I create a student table with three column id, student,age. show you this example

declare @id int 
select @id = 1
while @id >=1 and @id <= 1000
begin
    insert into student values(@id, 'jack' + convert(varchar(5), @id), 12)
    select @id = @id + 1
end

this is the result about the example

You don't need wildcards in the REPLACE - it just finds the string you enter for the second argument, so the following should work:

UPDATE dbo.xxx
SET Value = REPLACE(Value, '123', '')
WHERE ID <=4

If the column to replace is type text or ntext you need to cast it to nvarchar

UPDATE dbo.xxx
SET Value = REPLACE(CAST(Value as nVarchar(4000)), '123', '')
WHERE ID <=4

The article Everything you need to know about the ExpressionChangedAfterItHasBeenCheckedError error explains the behavior in great details.

The problem with you setup is that ngAfterViewInit lifecycle hook is executed after change detection processed DOM updates. And you're effectively changing the property that is used in the template in this hook which means that DOM needs to be re-rendered:

  ngAfterViewInit() {
    this.message = 'all done loading :)'; // needs to be rendered the DOM
  }

and this will require another change detection cycle and Angular by design only runs one digest cycle.

You basically have two alternatives how to fix it:

• update the property asynchronously either using setTimeout, Promise.then or asynchronous observable referenced in the template

• perform the property update in a hook before the DOM update - ngOnInit, ngDoCheck, ngAfterContentInit, ngAfterContentChecked.

This is a very informal answer to the question asked.

Can 3233 be written as the product of two other numbers bigger than 1? Is there any way to walk a path around all of the Seven Bridges of Königsberg without taking any bridge twice? These are examples of questions that share a common trait. It may not be obvious how to efficiently determine the answer, but if the answer is 'yes', then there's a short and quick to check proof. In the first case a non-trivial factorization of 51; in the second, a route for walking the bridges (fitting the constraints).

A decision problem is a collection of questions with yes or no answers that vary only in one parameter. Say the problem COMPOSITE={"Is n composite": n is an integer} or EULERPATH={"Does the graph G have an Euler path?": G is a finite graph}.

Now, some decision problems lend themselves to efficient, if not obvious algorithms. Euler discovered an efficient algorithm for problems like the "Seven Bridges of Königsberg" over 250 years ago.

On the other hand, for many decision problems, it's not obvious how to get the answer -- but if you know some additional piece of information, it's obvious how to go about proving you've got the answer right. COMPOSITE is like this: Trial division is the obvious algorithm, and it's slow: to factor a 10 digit number, you have to try something like 100,000 possible divisors. But if, for example, somebody told you that 61 is a divisor of 3233, simple long division is a efficient way to see that they're correct.

The complexity class NP is the class of decision problems where the 'yes' answers have short to state, quick to check proofs. Like COMPOSITE. One important point is that this definition doesn't say anything about how hard the problem is. If you have a correct, efficient way to solve a decision problem, just writing down the steps in the solution is proof enough.

Algorithms research continues, and new clever algorithms are created all the time. A problem you might not know how to solve efficiently today may turn out to have an efficient (if not obvious) solution tomorrow. In fact, it took researchers until 2002 to find an efficient solution to COMPOSITE! With all these advances, one really has to wonder: Is this bit about having short proofs just an illusion? Maybe every decision problem that lends itself to efficient proofs has an efficient solution? Nobody knows.

Perhaps the biggest contribution to this field came with the discovery a peculiar class of NP problems. By playing around with circuit models for computation, Stephen Cook found a decision problem of the NP variety that was provably as hard or harder than every other NP problem. An efficient solution for the boolean satisfiability problem could be used to create an efficient solution to any other problem in NP. Soon after, Richard Karp showed that a number of other decision problems could serve the same purpose. These problems, in a sense the "hardest" problems in NP, became known as NP-complete problems.

Of course, NP is only a class of decision problems. Many problems aren't naturally stated in this manner: "find the factors of N", "find the shortest path in the graph G that visits every vertex", "give a set of variable assignments that makes the following boolean expression true". Though one may informally talk about some such problems being "in NP", technically that doesn't make much sense -- they're not decision problems. Some of these problems might even have the same sort of power as an NP-complete problem: an efficient solution to these (non-decision) problems would lead directly to an efficient solution to any NP problem. A problem like this is called NP-hard.

If you only want the position, vp.getCurrentItem() will give it to you, no need to apply the onPageChangeListener() for that purpose alone.

In at least Postgres, you can use the alias name in the group by clause:

SELECT itemName as ItemName1, substring(itemName, 1,1) as FirstLetter, Count(itemName) FROM table1 GROUP BY ItemName1, FirstLetter;

I wouldn't recommend renaming an alias as a change in capitalization, that causes confusion.

You can use not filter on top of missing.

"query": {
  "filtered": {
     "query": {
        "match_all": {}
     },
     "filter": {
        "not": {
           "filter": {
              "missing": {
                 "field": "searchField"
              }
           }
        }
     }
  }
}

Assuming you're talking about a static library, DUMPBIN /SYMBOLS shows the functions and data objects in the library. If you're talking about an import library (a .lib used to refer to symbols exported from a DLL), then you want DUMPBIN /EXPORTS.

Note that for functions linked with the "C" binary interface, this still won't get you return values, parameters, or calling convention. That information isn't encoded in the .lib at all; you have to know that ahead of time (via prototypes in header files, for example) in order to call them correctly.

For functions linked with the C++ binary interface, the calling convention and arguments are encoded in the exported name of the function (also called "name mangling"). DUMPBIN /SYMBOLS will show you both the "mangled" function name as well as the decoded set of parameters.

Use String.substring(beginIndex, endIndex)

str.substring(0, str.length() - 2);

The substring begins at the specified beginIndex and extends to the character at index (endIndex - 1)

Assuming you know how big the item in the vector are:

std::vector<int> myArray;
myArray.resize (item_count, 0);
memcpy (&myArray.front(), source, item_count * sizeof(int));

Basically what you do is correct. Looking at redmine docs you linked to, it seems that suffix after the dot in the url denotes type of posted data (.json for JSON, .xml for XML), which agrees with the response you get - Processing by AttachmentsController#upload as XML. I guess maybe there's a bug in docs and to post binary data you should try using http://redmine/uploads url instead of http://redmine/uploads.xml.

Btw, I highly recommend very good and very popular Requests library for http in Python. It's much better than what's in the standard lib (urllib2). It supports authentication as well but I skipped it for brevity here.

import requests
with open('./x.png', 'rb') as f:
    data = f.read()
res = requests.post(url='http://httpbin.org/post',
                    data=data,
                    headers={'Content-Type': 'application/octet-stream'})

# let's check if what we sent is what we intended to send...
import json
import base64

assert base64.b64decode(res.json()['data'][len('data:application/octet-stream;base64,'):]) == data

UPDATE

To find out why this works with Requests but not with urllib2 we have to examine the difference in what's being sent. To see this I'm sending traffic to http proxy (Fiddler) running on port 8888:

Using Requests

import requests

data = 'test data'
res = requests.post(url='http://localhost:8888',
                    data=data,
                    headers={'Content-Type': 'application/octet-stream'})

we see

POST http://localhost:8888/ HTTP/1.1
Host: localhost:8888
Content-Length: 9
Content-Type: application/octet-stream
Accept-Encoding: gzip, deflate, compress
Accept: */*
User-Agent: python-requests/1.0.4 CPython/2.7.3 Windows/Vista

test data

and using urllib2

import urllib2

data = 'test data'    
req = urllib2.Request('http://localhost:8888', data)
req.add_header('Content-Length', '%d' % len(data))
req.add_header('Content-Type', 'application/octet-stream')
res = urllib2.urlopen(req)

we get

POST http://localhost:8888/ HTTP/1.1
Accept-Encoding: identity
Content-Length: 9
Host: localhost:8888
Content-Type: application/octet-stream
Connection: close
User-Agent: Python-urllib/2.7

test data

I don't see any differences which would warrant different behavior you observe. Having said that it's not uncommon for http servers to inspect User-Agent header and vary behavior based on its value. Try to change headers sent by Requests one by one making them the same as those being sent by urllib2 and see when it stops working.

  // First Initiate your map. Tie it to some ID in the HTML eg. 'MyMapID'
  var map = new google.maps.Map(
    document.getElementById('MyMapID'),
    {
      center: {
        lat: Some.latitude,
        lng: Some.longitude
      }
    }
  );
  // Create a new directionsService object.
  var directionsService = new google.maps.DirectionsService;
    directionsService.route({
      origin: origin.latitude +','+ origin.longitude,
      destination: destination.latitude +','+ destination.longitude,
      travelMode: 'DRIVING',
    }, function(response, status) {
      if (status === google.maps.DirectionsStatus.OK) {
        var directionsDisplay = new google.maps.DirectionsRenderer({
          suppressMarkers: true,
          map: map,
          directions: response,
          draggable: false,
          suppressPolylines: true, 
          // IF YOU SET `suppressPolylines` TO FALSE, THE LINE WILL BE
          // AUTOMATICALLY DRAWN FOR YOU.
        });

        // IF YOU WISH TO APPLY USER ACTIONS TO YOUR LINE YOU NEED TO CREATE A 
        // `polyLine` OBJECT BY LOOPING THROUGH THE RESPONSE ROUTES AND CREATING A 
        // LIST
        pathPoints = response.routes[0].overview_path.map(function (location) {
          return {lat: location.lat(), lng: location.lng()};
        });

        var assumedPath = new google.maps.Polyline({
         path: pathPoints, //APPLY LIST TO PATH
         geodesic: true,
         strokeColor: '#708090',
         strokeOpacity: 0.7,
         strokeWeight: 2.5
       });

       assumedPath.setMap(map); // Set the path object to the map

this method works well for me

$('#td_id').attr('class','new class');

Of course! jQuery is just a library that utilizes javascript after all.

You can use document.getElementById to get the element in question, then change its height accordingly, through element.style.height.

elementToChange = document.getElementById('collapseableEl');
elementToChange.style.height = '100%';

Wrap that up in a neat little function that caters for toggling back and forth and you have yourself a solution.

If speed is critical, you might want to look for the Aho-Corasick algorithm for sets of patterns.

It's a trie with failure links, that is, complexity is O(n+m+k), where n is the length of the input text, m the cumulative length of the patterns and k the number of matches. You just have to modify the algorithm to terminate after the first match is found.

As mentioned in a comment (and another answer as I typed) you need to register an event handler to catch the keydown or keypress event on a text box. This is because TextChanged is only fired when the TextBox loses focus

The below regex lets you match those characters you want to allow

Regex regex = new Regex(@"[0-9+\-\/\*\(\)]");
MatchCollection matches = regex.Matches(textValue);

and this does the opposite and catches characters that aren't allowed

Regex regex = new Regex(@"[^0-9^+^\-^\/^\*^\(^\)]");
MatchCollection matches = regex.Matches(textValue);

I'm not assuming there'll be a single match as someone could paste text into the textbox. in which case catch textchanged

textBox1.TextChanged += new TextChangedEventHandler(textBox1_TextChanged);
private void textBox1_TextChanged(object sender, EventArgs e)
{
    Regex regex = new Regex(@"[^0-9^+^\-^\/^\*^\(^\)]");
    MatchCollection matches = regex.Matches(textBox1.Text);
    if (matches.Count > 0) {
       //tell the user
    }
}

and to validate single key presses

textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
    // Check for a naughty character in the KeyDown event.
    if (System.Text.RegularExpressions.Regex.IsMatch(e.KeyChar.ToString(), @"[^0-9^+^\-^\/^\*^\(^\)]"))
    {
        // Stop the character from being entered into the control since it is illegal.
        e.Handled = true;
    }
}

If you have a multi-config (matrix) job, you do not have a JDK dropdown but need to configure the jdk as build axis.

According to the bash man page, $RANDOM is distributed between 0 and 32767; that is, it is an unsigned 15-bit value. Assuming $RANDOM is uniformly distributed, you can create a uniformly-distributed unsigned 30-bit integer as follows:

$(((RANDOM<<15)|RANDOM))

Since your range is not a power of 2, a simple modulo operation will only almost give you a uniform distribution, but with a 30-bit input range and a less-than-16-bit output range, as you have in your case, this should really be close enough:

PORT=$(( ((RANDOM<<15)|RANDOM) % 63001 + 2000 ))

Consider the following situation:

You are in the middle of a large, empty room, when a zombie suddenly attacks you.

You have no weapon.

Luckily, a fellow living human is standing in the doorway of the room.

"Quick!" you shout at him. "Throw me something I can hit the zombie with!"

Now consider:
You didn't specify (nor do you care) exactly what your friend will choose to toss;
...But it doesn't matter, as long as:

• It's something that can be tossed (He can't toss you the sofa)

• It's something that you can grab hold of (Let's hope he didn't toss a shuriken)

• It's something you can use to bash the zombie's brains out (That rules out pillows and such)

It doesn't matter whether you get a baseball bat or a hammer -
as long as it implements your three conditions, you're good.

To sum it up:

When you write an interface, you're basically saying: "I need something that..."

The class you're looking for already exists. Map.Entry:

public static Entry<Integer,String> myMethod(){
    return new SimpleEntry<>(12, "value");
}

And later:

Entry<Integer,String> valueAndIndex = myMethod();
int index = valueAndIndex.getKey();
String value = valueAndIndex.getValue();

It's just a simple two-field data structure that stores a key and value. If you need to do any special processing, store more than two fields, or have any other fringe case, you should make your own class, but otherwise, Map.Entry is one of the more underutilized Java classes and is perfect for situations like these.

As shown below, range only supports integers:

>>> range(15.0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: range() integer end argument expected, got float.
>>> range(15)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]
>>>

However, c/10 is a float because / always returns a float.

Before you put it in range, you need to make c/10 an integer. This can be done by putting it in int:

range(int(c/10))

or by using //, which returns an integer:

range(c//10)

Instead of - fd.append( 'userfile', $('#userfile')[0].files[0]);

Use - fd.append( 'file', $('#userfile')[0].files[0]);

According to the docs, you can just do:

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from USER_INDEXES

or

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from ALL_INDEXES

if you want all indexes...

If you need the difference in days accounting up to the second:

SELECT TIMESTAMPDIFF(SECOND,'2010-09-21 21:40:36','2010-10-08 18:23:13')/86400 AS diff

It will return
diff
16.8629

You should run the installer as administrator.

1. Run the command prompt as administrator
2. cd directory where msi file is present
3. launch msi file by typing the name in the command prompt
4. You should be happy to see all node commands work from new command prompt shell

This is an expansion of one of the solutions provided in Jakub's answer

I was faced with a situation where the commits I needed to roll back were somewhat complex, with several of the commits being merge commits, and I needed to avoid rewriting history. I was not able to use a series of git revert commands because I eventually ran into conflicts between the reversion changes being added. I ended up using the following steps.

First, check out the contents of the target commit while leaving HEAD at the tip of the branch:

$ git checkout -f <target-commit> -- .

(The -- makes sure <target-commit> is interpreted as a commit rather than a file; the . refers to the current directory.)

Then, determine what files were added in the commits being rolled back, and thus need to be deleted:

$ git diff --name-status --cached <target-commit>

Files that were added should show up with an "A" at the beginning of the line, and there should be no other differences. Now, if any files need to be removed, stage these files for removal:

$ git rm <filespec>[ <filespec> ...]

Finally, commit the reversion:

$ git commit -m 'revert to <target-commit>'

If desired, make sure that we're back to the desired state:

$git diff <target-commit> <current-commit>

There should be no differences.

The error "only length-1 arrays can be converted to Python scalars" is raised when the function expects a single value but you pass an array instead.

If you look at the call signature of np.int, you'll see that it accepts a single value, not an array. In general, if you want to apply a function that accepts a single element to every element in an array, you can use np.vectorize:

import numpy as np
import matplotlib.pyplot as plt

def f(x):
    return np.int(x)
f2 = np.vectorize(f)
x = np.arange(1, 15.1, 0.1)
plt.plot(x, f2(x))
plt.show()

You can skip the definition of f(x) and just pass np.int to the vectorize function: f2 = np.vectorize(np.int).

Note that np.vectorize is just a convenience function and basically a for loop. That will be inefficient over large arrays. Whenever you have the possibility, use truly vectorized functions or methods (like astype(int) as @FFT suggests).

The correct approach is to use preprocessing

For example

th:field="*{__${myVar}__}"

Python is upset because you are attempting to assign a value to something that can't be assigned a value.

((t[1])/length) * t[1] += string

When you use an assignment operator, you assign the value of what is on the right to the variable or element on the left. In your case, there is no variable or element on the left, but instead an interpreted value: you are trying to assign a value to something that isn't a "container".

Based on what you've written, you're just misunderstanding how this operator works. Just switch your operands, like so.

string += str(((t[1])/length) * t[1])

Note that I've wrapped the assigned value in str in order to convert it into a str so that it is compatible with the string variable it is being assigned to. (Numbers and strings can't be added together.)

select ROUND(CASE 

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))!='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))!='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

else CONVERT( float, REPLACE(isnull( value1,''),',','')) end,0)  from Tablename where    ID="123" 

The last answer worked for me for a few months, then stopped recognizing the filename, as adeneo commented ...

@Scott's answer here is working for me:

Download file from an ASP.NET Web API method using AngularJS

unicode is meant to handle text. Text is a sequence of code points which may be bigger than a single byte. Text can be encoded in a specific encoding to represent the text as raw bytes(e.g. utf-8, latin-1...).

Note that unicode is not encoded! The internal representation used by python is an implementation detail, and you shouldn't care about it as long as it is able to represent the code points you want.

On the contrary str in Python 2 is a plain sequence of bytes. It does not represent text!

You can think of unicode as a general representation of some text, which can be encoded in many different ways into a sequence of binary data represented via str.

Note: In Python 3, unicode was renamed to str and there is a new bytes type for a plain sequence of bytes.

Some differences that you can see:

>>> len(u'à')  # a single code point
1
>>> len('à')   # by default utf-8 -> takes two bytes
2
>>> len(u'à'.encode('utf-8'))
2
>>> len(u'à'.encode('latin1'))  # in latin1 it takes one byte
1
>>> print u'à'.encode('utf-8')  # terminal encoding is utf-8
à
>>> print u'à'.encode('latin1') # it cannot understand the latin1 byte
?

Note that using str you have a lower-level control on the single bytes of a specific encoding representation, while using unicode you can only control at the code-point level. For example you can do:

>>> 'àèìòù'
'\xc3\xa0\xc3\xa8\xc3\xac\xc3\xb2\xc3\xb9'
>>> print 'àèìòù'.replace('\xa8', '')
à?ìòù

What before was valid UTF-8, isn't anymore. Using a unicode string you cannot operate in such a way that the resulting string isn't valid unicode text. You can remove a code point, replace a code point with a different code point etc. but you cannot mess with the internal representation.

Ok I have used the last week to massively rewrite my code to precisely fit your test. You can now copy this 1:1 and it will immediately work - including setSingleLine(). Please remember to adjust MIN_TEXT_SIZE and MAX_TEXT_SIZE if you're going for extreme values.

Converging algorithm looks like this:

for (float testSize; (upperTextSize - lowerTextSize) > mThreshold;) {

    // Go to the mean value...
    testSize = (upperTextSize + lowerTextSize) / 2;

    // ... inflate the dummy TextView by setting a scaled textSize and the text...
    mTestView.setTextSize(TypedValue.COMPLEX_UNIT_SP, testSize / mScaledDensityFactor);
    mTestView.setText(text);

    // ... call measure to find the current values that the text WANTS to occupy
    mTestView.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
    int tempHeight = mTestView.getMeasuredHeight();

    // ... decide whether those values are appropriate.
    if (tempHeight >= targetFieldHeight) {
        upperTextSize = testSize; // Font is too big, decrease upperSize
    }
    else {
        lowerTextSize = testSize; // Font is too small, increase lowerSize
    }
}

And the whole class can be found here.

The result is very flexible now. This works the same declared in xml like so:

<com.example.myProject.AutoFitText
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="4"
    android:text="@string/LoremIpsum" />

... as well as built programmatically like in your test.

I really hope you can use this now. You can call setText(CharSequence text) now to use it by the way. The class takes care of stupendously rare exceptions and should be rock-solid. The only thing that the algorithm does not support yet is:

• Calls to setMaxLines(x) where x >= 2

But I have added extensive comments to help you build this if you wish to!

Please note:

If you just use this normally without limiting it to a single line then there might be word-breaking as you mentioned before. This is an Android feature, not the fault of the AutoFitText. Android will always break words that are too long for a TextView and it's actually quite a convenience. If you want to intervene here than please see my comments and code starting at line 203. I have already written an adequate split and the recognition for you, all you'd need to do henceforth is to devide the words and then modify as you wish.

In conclusion: You should highly consider rewriting your test to also support space chars, like so:

final Random _random = new Random();
final String ALLOWED_CHARACTERS = "qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM1234567890";
final int textLength = _random.nextInt(80) + 20;
final StringBuilder builder = new StringBuilder();
for (int i = 0; i < textLength; ++i) {
    if (i % 7 == 0 && i != 0) {
        builder.append(" ");
    }
    builder.append(ALLOWED_CHARACTERS.charAt(_random.nextInt(ALLOWED_CHARACTERS.length())));
}
((AutoFitText) findViewById(R.id.textViewMessage)).setText(builder.toString());

This will produce very beutiful (and more realistic) results.
You will find commenting to get you started in this matter as well.

Good luck and best regards

The only thing that worked for me:

g.drawOval((getWidth()-200)/2,(getHeight()-200)/2, 200, 200);    

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

You get the warning because you did not assign a value to one, which is a pointer. This is undefined behavior.

You should declare it like this:

Vector* one = malloc(sizeof(Vector));

or like this:

Vector one;

in which case you need to replace -> operator with . like this:

one.a = 12;
one.b = 13;
one.c = -11;

Finally, in C99 and later you can use designated initializers:

Vector one = {
   .a = 12
,  .b = 13
,  .c = -11
};

Your code could look more like:

<?php
session_start(); $username = $password = $userError = $passError = '';
if(isset($_POST['sub'])){
  $username = $_POST['username']; $password = $_POST['password'];
  if($username === 'admin' && $password === 'password'){
    $_SESSION['login'] = true; header('LOCATION:wherever.php'); die();
  }
  if($username !== 'admin')$userError = 'Invalid Username';
  if($password !== 'password')$passError = 'Invalid Password';
}
?>

You could use the following, which reports the timezone offset from GMT in minutes:

new Date().getTimezoneOffset();

Note : - this function return a negative number.

The best solution for your browser load time would be to use a server side script to join them all together into one big .js file. Make sure to gzip/minify the final version. Single request - nice and compact.

Alternatively, you can use DOM to create a <script> tag and set the src property on it then append it to the <head>. If you need to wait for that functionality to load, you can make the rest of your javascript file be called from the load event on that script tag.

This function is based on the functionality of jQuery $.getScript()

function loadScript(src, f) {
  var head = document.getElementsByTagName("head")[0];
  var script = document.createElement("script");
  script.src = src;
  var done = false;
  script.onload = script.onreadystatechange = function() { 
    // attach to both events for cross browser finish detection:
    if ( !done && (!this.readyState ||
      this.readyState == "loaded" || this.readyState == "complete") ) {
      done = true;
      if (typeof f == 'function') f();
      // cleans up a little memory:
      script.onload = script.onreadystatechange = null;
      head.removeChild(script);
    }
  };
  head.appendChild(script);
}

// example:
loadScript('/some-other-script.js', function() { 
   alert('finished loading');
   finishSetup();
 });

It can be done in a single command. You need to set the IDENTITY property for "auto number":

ALTER TABLE MyTable ADD mytableID int NOT NULL IDENTITY (1,1) PRIMARY KEY

More precisely, to set a named table level constraint:

ALTER TABLE MyTable
   ADD MytableID int NOT NULL IDENTITY (1,1),
   CONSTRAINT PK_MyTable PRIMARY KEY CLUSTERED (MyTableID)

See ALTER TABLE and IDENTITY on MSDN

You can also create shapes directly inside the item tag, in case you want to add some more details to your view, like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid android:color="#81ba73" />
            <corners android:radius="6dp" />
        </shape>
        <ripple android:color="#c62828"/>
    </item>
    <item android:state_enabled="false">
        <shape>
            <solid android:color="#788e73" />
            <corners android:radius="6dp" />
        </shape>
    </item>
    <item>
        <shape>
            <solid android:color="#add8a3" />
            <corners android:radius="6dp" />
        </shape>
    </item>
</selector>

Beware that Android will cycle through the items from top to bottom, therefore, you must place the item without condition on the bottom of the list (so it acts like a default/fallback).

Basically, this is what worked for me:

-apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif 

P.S. This works on all systems.

You cannot simply add a link using CSS. CSS is used for styling.

You can style your using CSS.

If you want to give a link dynamically to then I will advice you to use jQuery or Javascript.

You can accomplish that very easily using jQuery.

I have done a sample for you. You can refer that.

URL : http://jsfiddle.net/zyk9w/

$('#link').attr('href','http://www.google.com');

This single line will do the trick.

The following implementation of a PriorityQueue uses SortedSet from the System library.

using System;
using System.Collections.Generic;

namespace CDiggins
{
    interface IPriorityQueue<T, K> where K : IComparable<K>
    {
        bool Empty { get; }
        void Enqueue(T x, K key);
        void Dequeue();
        T Top { get; }
    }

    class PriorityQueue<T, K> : IPriorityQueue<T, K> where K : IComparable<K>
    {
        SortedSet<Tuple<T, K>> set;

        class Comparer : IComparer<Tuple<T, K>> {
            public int Compare(Tuple<T, K> x, Tuple<T, K> y) {
                return x.Item2.CompareTo(y.Item2);
            }
        }

        PriorityQueue() { set = new SortedSet<Tuple<T, K>>(new Comparer()); }
        public bool Empty { get { return set.Count == 0;  } }
        public void Enqueue(T x, K key) { set.Add(Tuple.Create(x, key)); }
        public void Dequeue() { set.Remove(set.Max); }
        public T Top { get { return set.Max.Item1; } }
    }
}

You can try RandomStringUtils class from apache.commons:

import org.apache.commons.lang3.RandomStringUtils;

final int SHORT_ID_LENGTH = 8;

// all possible unicode characters
String shortId = RandomStringUtils.random(SHORT_ID_LENGTH);

Please keep in mind, that it will contain all possible characters which is neither URL nor human friendly.

So check out other methods too:

// HEX: 0-9, a-f. For example: 6587fddb, c0f182c1
shortId = RandomStringUtils.random(8, "0123456789abcdef"); 

// a-z, A-Z. For example: eRkgbzeF, MFcWSksx
shortId = RandomStringUtils.randomAlphabetic(8); 

// 0-9. For example: 76091014, 03771122
shortId = RandomStringUtils.randomNumeric(8); 

// a-z, A-Z, 0-9. For example: WRMcpIk7, s57JwCVA
shortId = RandomStringUtils.randomAlphanumeric(8); 

As others said probability of id collision with smaller id can be significant. Check out how birthday problem applies to your case. You can find nice explanation how to calculate approximation in this answer.

I wrote a very tiny plugin called "once" which do that. Execute off and on in element.

$.fn.once = function(a, b) {
    return this.each(function() {
        $(this).off(a).on(a,b);
    });
};

And simply:

$(element).once('click', function(){
});

In the jQuery source code we have jQuery.fn = jQuery.prototype = {...} since jQuery.prototype is an object the value of jQuery.fn will simply be a reference to the same object that jQuery.prototype already references.

To confirm this you can check jQuery.fn === jQuery.prototype if that evaluates true (which it does) then they reference the same object

The total of 7 numbers in an array can be created as:

import java.util.*;
class Sum
{
   public static void main(String arg[])
   {
     int a[]=new int[7];
     int total=0;
     Scanner n=new Scanner(System.in);
     System.out.println("Enter the no. for total");

     for(int i=0;i<=6;i++) 
     {
       a[i]=n.nextInt();
       total=total+a[i];
      }
       System.out.println("The total is :"+total);
    }
}

Here's an alternative following the last answer

declare @t tinyint,@v tinyint
set @t=23
set @v=232
Select replace(str(@t,4),' ','0'),replace(str(@t,5),' ','0')

This will work on any number and by varying the length of the str() function you can stipulate how many leading zeros you require. Provided of course that your string length is always >= maximum number of digits your number type can hold.

Thanks to "msoliman" for his hint, however his answer doesn't give clear solution for those who doesn't have VS2010
For example I have VS2012 and VS2013 and there are no such KEYs in system registry.

Solution:
Edit file: "[Python_install_loc]/Lib/distutils/msvc9compiler.py"
Change on line 224:

productdir = Reg.get_value(r"%s\Setup\VC" % vsbase,
                               "productdir")

to:

productdir = "C:\Program Files (x86)\Microsoft Visual Studio [your_vs_version(11/12...)]\VC"

and that should work

DECLARE @MAX INT
@MAX = (SELECT MAX(VALUE) 
               FROM (SELECT 1 AS VALUE UNION 
                     SELECT 2 AS VALUE) AS T1)

Without knowing the exact regex implementation you're making use of, I can only give general advice. (The syntax I will be perl as that's what I know, some languages will require tweaking)

Looking at ABC: (z) jan 02 1999 \n

• The first thing to match is ABC: So using our regex is /ABC:/

• You say ABC is always at the start of the string so /^ABC/ will ensure that ABC is at the start of the string.

• You can match spaces with the \s (note the case) directive. With all directives you can match one or more with + (or 0 or more with *)

• You need to escape the usage of ( and ) as it's a reserved character. so \(\)

• You can match any non space or newline character with .

• You can match anything at all with .* but you need to be careful you're not too greedy and capture everything.

So in order to capture what you've asked. I would use /^ABC:\s*\(.+?\)\s*(.+)$/

Which I read as:

Begins with ABC:

May have some spaces

has (

has some characters

has )

may have some spaces

then capture everything until the end of the line (which is $).

I highly recommend keeping a copy of the following laying about http://www.cheatography.com/davechild/cheat-sheets/regular-expressions/

For the moment it is still not supported out of the box by Roslyn compiler ...

Until now, the extension properties were not seen as valuable enough to be included in the previous versions of C# standard. C# 7 and C# 8.0 have seen this as proposal champion but it wasn't released yet, most of all because even if there is already an implementation, they want to make it right from the start.

But it will ...

There is an extension members item in the C# 7 work list so it may be supported in the near future. The current status of extension property can be found on Github under the related item.

However, there is an even more promising topic which is the "extend everything" with a focus on especially properties and static classes or even fields.

Moreover you can use a workaround

As specified in this article, you can use the TypeDescriptor capability to attach an attribute to an object instance at runtime. However, it is not using the syntax of the standard properties.
It's a little bit different from just syntactic sugar adding a possibility to define an extended property like
string Data(this MyClass instance) as an alias for extension method
string GetData(this MyClass instance) as it stores data into the class.

I hope that C#7 will provide a full featured extension everything (properties and fields), however on that point, only time will tell.

And feel free to contribute as the software of tomorrow will come from the community.

Update: August 2016

As dotnet team published what's new in C# 7.0 and from a comment of Mads Torgensen:

Extension properties: we had a (brilliant!) intern implement them over the summer as an experiment, along with other kinds of extension members. We remain interested in this, but it’s a big change and we need to feel confident that it’s worth it.

It seems that extension properties and other members, are still good candidates to be included in a future release of Roslyn, but maybe not the 7.0 one.

Update: May 2017

The extension members has been closed as duplicate of extension everything issue which is closed too. The main discussion was in fact about Type extensibility in a broad sense. The feature is now tracked here as a proposal and has been removed from 7.0 milestone.

Update: August, 2017 - C# 8.0 proposed feature

While it still remains only a proposed feature, we have now a clearer view of what would be its syntax. Keep in mind that this will be the new syntax for extension methods as well:

public interface IEmployee 
{
    public decimal Salary { get; set; }
}

public class Employee
{
    public decimal Salary { get; set; }
}

public extension MyPersonExtension extends Person : IEmployee
{
    private static readonly ConditionalWeakTable<Person, Employee> _employees = 
        new ConditionalWeakTable<Person, Employee>();


    public decimal Salary
    {
        get 
        {
            // `this` is the instance of Person
            return _employees.GetOrCreate(this).Salary; 
        }
        set 
        {
            Employee employee = null;
            if (!_employees.TryGetValue(this, out employee)
            {
                employee = _employees.GetOrCreate(this);
            }
            employee.Salary = value;
        }
    }
}

IEmployee person = new Person();
var salary = person.Salary;

Similar to partial classes, but compiled as a separate class/type in a different assembly. Note you will also be able to add static members and operators this way. As mentioned in Mads Torgensen podcast, the extension won't have any state (so it cannot add private instance members to the class) which means you won't be able to add private instance data linked to the instance. The reason invoked for that is it would imply to manage internally dictionaries and it could be difficult (memory management, etc...). For this, you can still use the TypeDescriptor/ConditionalWeakTable technique described earlier and with the property extension, hides it under a nice property.

Syntax is still subject to change as implies this issue. For example, extends could be replaced by for which some may feel more natural and less java related.

Update December 2018 - Roles, Extensions and static interface members

Extension everything didn't make it to C# 8.0, because of some of drawbacks explained as the end of this GitHub ticket. So, there was an exploration to improve the design. Here, Mads Torgensen explains what are roles and extensions and how they differs:

Roles allow interfaces to be implemented on specific values of a given type. Extensions allow interfaces to be implemented on all values of a given type, within a specific region of code.

It can be seen at a split of previous proposal in two use cases. The new syntax for extension would be like this:

public extension ULongEnumerable of ulong
{
    public IEnumerator<byte> GetEnumerator()
    {
        for (int i = sizeof(ulong); i > 0; i--)
        {
            yield return unchecked((byte)(this >> (i-1)*8));
        }
    }
}

then you would be able to do this:

foreach (byte b in 0x_3A_9E_F1_C5_DA_F7_30_16ul)
{
    WriteLine($"{e.Current:X}");
}

And for a static interface:

public interface IMonoid<T> where T : IMonoid<T>
{
    static T operator +(T t1, T t2);
    static T Zero { get; }
}

Add an extension property on int and treat the int as IMonoid<int>:

public extension IntMonoid of int : IMonoid<int>
{
    public static int Zero => 0;
}

You are giving multiple Content-Type headers. application/vnd.ms-excel is enough.

And there are couple of syntax error too. To statement termination with ; on the echo statement and wrong filename extension.

header("Content-Type:   application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=abc.xls");  //File name extension was wrong
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
echo "Some Text"; //no ending ; here

this worked for me, no root,Android 6.0, Android Studio, Acatel U3:

    Runtime runtime = Runtime.getRuntime();
    try
    {
        Process  mIpAddrProcess = runtime.exec("/system/bin/ping -c 1 " + IP);
        int mExitValue = mIpAddrProcess.waitFor();
        System.out.println(" mExitValue "+mExitValue);
        if(mExitValue==0){

I'm working on a similar project and I guess my code may help in the above situation

Here is the overview of what i'm doing

My project Has two fragments Called "FragmentA" and "FragmentB"

-FragmentA Contains one list View,when you click an item in FragmentA It's INDEX is passed to FragmentB using Communicator interface

• The design pattern is totally based on the concept of java interfaces that says "interface reference variables can refer to a subclass object"
• Let MainActivity implement the interface provided by fragmentA(otherwise we can't make interface reference variable to point to MainActivity)
• In the below code communicator object is made to refer to MainActivity's object by using "setCommunicator(Communicatot c)" method present in fragmentA.

• I'm triggering respond() method of interface from FrgamentA using the MainActivity's reference.

  Interface communcator is defined inside fragmentA, this is to provide least access previlage to communicator interface.

below is my complete working code

FragmentA.java

public class FragmentA extends Fragment implements OnItemClickListener {

ListView list;
Communicator communicater;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    return inflater.inflate(R.layout.fragmenta, container,false);
}

public void setCommunicator(Communicator c){
    communicater=c;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);
    communicater=(Communicator) getActivity();
    list = (ListView) getActivity().findViewById(R.id.lvModularListView);
    ArrayAdapter<?> adapter = ArrayAdapter.createFromResource(getActivity(),
            R.array.items, android.R.layout.simple_list_item_1);
    list.setAdapter(adapter);
    list.setOnItemClickListener(this);

}

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int index, long arg3) {
communicater.respond(index);

}

public interface Communicator{
    public void respond(int index);
}

}

fragmentB.java

public class FragmentA extends Fragment implements OnItemClickListener {

ListView list;
Communicator communicater;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    return inflater.inflate(R.layout.fragmenta, container,false);
}

public void setCommunicator(Communicator c){
    communicater=c;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);
    communicater=(Communicator) getActivity();
    list = (ListView) getActivity().findViewById(R.id.lvModularListView);
    ArrayAdapter<?> adapter = ArrayAdapter.createFromResource(getActivity(),
            R.array.items, android.R.layout.simple_list_item_1);
    list.setAdapter(adapter);
    list.setOnItemClickListener(this);

}

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int index, long arg3) {
communicater.respond(index);

}

public interface Communicator{
    public void respond(int index);
}

}

MainActivity.java

public class MainActivity extends Activity implements FragmentA.Communicator {
FragmentManager manager=getFragmentManager();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    FragmentA fragA=(FragmentA) manager.findFragmentById(R.id.fragmenta);
    fragA.setCommunicator(this);


}

@Override
public void respond(int i) {
    // TODO Auto-generated method stub

FragmentB FragB=(FragmentB) manager.findFragmentById(R.id.fragmentb);
FragB.changetext(i);
}

Create repository on dockerhub :

$docker tag IMAGE_ID UsernameOnDockerhub/repoNameOnDockerhub:latest

$docker push UsernameOnDockerhub/repoNameOnDockerhub:latest

Note : here "repoNameOnDockerhub" : repository with the name you are mentioning has to be present on dockerhub

"latest" : is just tag

Windows 7 requires that you intentionally ask for certain privileges so that a malicious program can't do bad things to you. If the free calculator you downloaded needed to be run as an administrator, you would know something is up. There are OS commands to elevate the privilege of your application (which will request confirmation from the user).

A good description can be found at:

Use the .readline() method (Python 2 docs, Python 3 docs):

with open('myfile.txt') as f:
    first_line = f.readline()

Some notes:

1. As noted in the docs, unless it is the only line in the file, the string returned from f.readline() will contain a trailing newline. You may wish to use f.readline().strip() instead to remove the newline.
2. The with statement automatically closes the file again when the block ends.
3. The with statement only works in Python 2.5 and up, and in Python 2.5 you need to use from __future__ import with_statement
4. In Python 3 you should specify the file encoding for the file you open. Read more...

By default, IE displays webpages in the Intranet zone in compatibility view. To change this:

• Press Alt to display the IE menu.
• Choose Tools | Compatibility View settings
• Remove the checkmark next to Display intranet sites in Compatibility View.
• Choose Close.

At this point, IE should rely on the webpage itself (or any relevant group policies) to determine the compatibility settings for your Intranet webpages.

Note that certain sites may no longer function correctly after making this change. You can use the same dialog box to add specific sites to enable compatibility view when needed.

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

With React Functional way

import React, { useEffect } from "react";
import ReactDOM from "react-dom";
import Button from "@material-ui/core/Button";

const App = () => {
  const saySomething = (something) => {
    console.log(something);
  };
  useEffect(() => {
    saySomething("from useEffect");
  });
  const handleClick = (e) => {
    saySomething("element clicked");
  };
  return (
    <Button variant="contained" color="primary" onClick={handleClick}>
      Hello World
    </Button>
  );
};

ReactDOM.render(<App />, document.querySelector("#app"));

Perhaps it is indirect to gdb (because it's an IDE), but my recommendations would be KDevelop. Being quite spoiled with Visual Studio's debugger (professionally at work for many years), I've so far felt the most comfortable debugging in KDevelop (as hobby at home, because I could not afford Visual Studio for personal use - until Express Edition came out). It does "look something similar to" Visual Studio compared to other IDE's I've experimented with (including Eclipse CDT) when it comes to debugging step-through, step-in, etc (placing break points is a bit awkward because I don't like to use mouse too much when coding, but it's not difficult).

TLDR:

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org -r requirements.txt -vvv

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org <packageName> -vvv

So, Having 30+ answers to the question already, but nothing was working for me in June 2020 (while in lockdown ).
all were given in different moments of past. I will try to make this answer work for all times in future. The problem is while pip installs package it tries to connect with host URL where package is stored and doesn't trust the URL while downloading it.

There are two ways we can solve this: Easy and non-secure: 1. check which URL is hit by pip to download the package.

pip install <packageName> -vvv

if you will carefully check the output, you will see it might be going to some URL like pypi.org or may be pypi.python.org.

if it is, just add trusted host option to the command like below:

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org <packageName> -vvv

or if you are using requirements file:

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org -r requirements.txt -vvv

Secure way:

Go to each of these URL and download their public cert (just google how to download), create a chain, store it as .pem file and run below command:

pip --cert YourPemFile.pem install <packageName>

just use

file:///

works in IE, Firefox and Chrome as far as I can tell.

In my case when i run select query it works and gives desired data. But when i run query like

select * from users where email = "[email protected]"

It shows this error

ERROR:  column "[email protected]" does not exist
LINE 2: select * from users where email = "[email protected]...
                                          ^
SQL state: 42703
Character: 106

Then i use single quotes instead of double quotes for match condition, it works. for ex.

select * from users where email = '[email protected]'

Well, like (almost) every console program for unix-like systems, git does not tell you anything if a command succeeds. It prints out something only if there's something wrong.

However if you want to be sure of what just happened, just type

git status

and see which changes are going to be committed and which not. I suggest you to use this before every commit, just to be sure that you are not forgetting anything.

Since you seem new to git, here is a link to a free online book that introduces you to git. It's very useful, it writes about basics as well as well known different workflows: http://git-scm.com/book

Changing a variable doesn't magically execute code within the if-block. Place the common code in a function, then bind the event, and call the function:

$(document).ready(function() {
    // Optimalisation: Store the references outside the event handler:
    var $window = $(window);
    var $pane = $('#pane1');

    function checkWidth() {
        var windowsize = $window.width();
        if (windowsize > 440) {
            //if the window is greater than 440px wide then turn on jScrollPane..
            $pane.jScrollPane({
               scrollbarWidth:15, 
               scrollbarMargin:52
            });
        }
    }
    // Execute on load
    checkWidth();
    // Bind event listener
    $(window).resize(checkWidth);
});

If you want to take the formatted value of input do this :

$("input").datepicker({ dateFormat: 'dd, mm, yy' });

later in your code when the date is set you could get it by

dateVariable = $("input").val();

If you want just to take a formatted value with datepicker you might want to use the utility

dateString = $.datepicker.formatDate('dd, MM, yy', new Date("20 April 2012"));

I've updated the jsfiddle for experimenting with this

I'm using this, and works fine for me (with org.json.*):

package com.project1.helpers;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import java.util.HashMap;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class JSONUtils {

    public static boolean areEqual(Object ob1, Object ob2) throws JSONException {
        Object obj1Converted = convertJsonElement(ob1);
        Object obj2Converted = convertJsonElement(ob2);
        return obj1Converted.equals(obj2Converted);
    }

    private static Object convertJsonElement(Object elem) throws JSONException {
        if (elem instanceof JSONObject) {
            JSONObject obj = (JSONObject) elem;
            Iterator<String> keys = obj.keys();
            Map<String, Object> jsonMap = new HashMap<>();
            while (keys.hasNext()) {
                String key = keys.next();
                jsonMap.put(key, convertJsonElement(obj.get(key)));
            }
            return jsonMap;
        } else if (elem instanceof JSONArray) {
            JSONArray arr = (JSONArray) elem;
            Set<Object> jsonSet = new HashSet<>();
            for (int i = 0; i < arr.length(); i++) {
                jsonSet.add(convertJsonElement(arr.get(i)));
            }
            return jsonSet;
        } else {
            return elem;
        }
    }
}

After adding JTextArea into JScrollPane here:

scroll = new JScrollPane(display);

You don't need to add it again into other container like you do:

middlePanel.add(display);

Just remove that last line of code and it will work fine. Like this:

    middlePanel=new JPanel();
    middlePanel.setBorder(new TitledBorder(new EtchedBorder(), "Display Area"));

    // create the middle panel components

    display = new JTextArea(16, 58);
    display.setEditable(false); // set textArea non-editable
    scroll = new JScrollPane(display);
    scroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);

    //Add Textarea in to middle panel
    middlePanel.add(scroll);

JScrollPane is just another container that places scrollbars around your component when its needed and also has its own layout. All you need to do when you want to wrap anything into a scroll just pass it into JScrollPane constructor:

new JScrollPane( myComponent ) 

or set view like this:

JScrollPane pane = new JScrollPane ();
pane.getViewport ().setView ( myComponent );

Additional:

Here is fully working example since you still did not get it working:

public static void main ( String[] args )
{
    JPanel middlePanel = new JPanel ();
    middlePanel.setBorder ( new TitledBorder ( new EtchedBorder (), "Display Area" ) );

    // create the middle panel components

    JTextArea display = new JTextArea ( 16, 58 );
    display.setEditable ( false ); // set textArea non-editable
    JScrollPane scroll = new JScrollPane ( display );
    scroll.setVerticalScrollBarPolicy ( ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS );

    //Add Textarea in to middle panel
    middlePanel.add ( scroll );

    // My code
    JFrame frame = new JFrame ();
    frame.add ( middlePanel );
    frame.pack ();
    frame.setLocationRelativeTo ( null );
    frame.setVisible ( true );
}

And here is what you get:

This is a case that could have possibly occurred and what solved my error:

In the https://developers.facebook.com/quickstarts after you run

OSX/Linux:

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

Windows:

keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | openssl sha1 -binary | openssl base64

When Enter keystore password: is asked you may have accidentally typed a wrong password, the default password is "android". Typing any other password will give you a different/wrong hash key. Paste the correct hash key in the Key Hashes field on your app page

This solved my problem, hope this helps whoever made this particular error that I made

It really depends on how you write your bash scripts. If your /bin/sh is symlinked to bash, when bash is invoked as sh, some features are unavailable.

If you want bash-specific, non-POSIX features, use #!/bin/bash

I have been tearing my hair out with trying to parse and use data returned form a JSON query/ api call. Im not sure exactly where i was going wrong, i feel like i have been circling the answer for days, chasing various error codes like:

"Cannot find 'iterableDiff' pipe supporting object"

"Generic TYpe Array requires one argument(s)"

JSON parsing Errors, and im sure others

Im assuming i just had the wrong combination of fixes.

So here's a bit of a summary of gotchas and things to look for.

Firstly check the result of your api calls, your results may be in the form of an object, an array, or an array of objects.

i wont go into it too much, suffice to say the OP's original Error of not being iterable is generally caused by you trying to iterate an object, not an Array.

Heres some of my debugging results showing variables of both arrays and objects

So as we generally would like to iterate over our JSON result we need to ensure it is in the form of an Array. I tried numerous examples, and perhaps knowing what i know now some of those would in fact work, but the approach i went with was indeed to implement a pipe and the code i used was that the posted by t.888

   transform(obj: {[key: string]: any}, arg: string) {
if (!obj)
        return undefined;

return arg === 'keyval' ?
    Object.keys(obj).map((key) => ({ 'key': key, 'value': obj[key] })) :
  arg === 'key' ?
    Object.keys(obj) :
  arg === 'value' ?
    Object.keys(obj).map(key => obj[key]) :
  null;

Honestly i think one of the things that was getting me was the lack of error handling, by adding the 'return undefined' call i believe we are now allowing for non expected data to be sent to the pipe, which obviously was occurring in my case.

if you don't want to deal with argument to the pipe (and look i don't think it's necessary in most cases) you can just return the following

       if (!obj)
          return undefined;
       return Object.keys(obj);

Some Notes on creating your pipe and page or component that uses that pipe

is i was receiving errors about ‘name_of_my_pipe’ not being found

Use the ‘ionic generate pipe’ command from the CLI to ensure the pipe modules.ts are created and referenced correctly. ensure you add the following to the mypage.module.ts page.

import { PipesModule } from ‘…/…/pipes/pipes.module’;

(not sure if this changes if you also have your own custom_module, you may also need to add it to the custommodule.module.ts)

if you used the 'ionic generate page' command to make your page, but decide to use that page as your main page, remember to remove the page reference from app.module.ts (here's another answer i posted dealing with that https://forum.ionicframework.com/t/solved-pipe-not-found-in-custom-component/95179/13?u=dreaser

In my searching for answers there where a number of ways to display the data in the html file, and i don't understand enough to explain the differences. You may find it better to use one over another in certain scenarios.

            <ion-item *ngFor="let myPost of posts">
                  <img src="https://somwhereOnTheInternet/{{myPost.ImageUrl}}"/>
                  <img src="https://somwhereOnTheInternet/{{posts[myPost].ImageUrl}}"/>
                  <img [src]="'https://somwhereOnTheInternet/' + myPost.ImageUrl" />
            </ion-item>

However what worked that allowed me to display both the value and the key was the following:

    <ion-list>  
      <ion-item *ngFor="let myPost of posts  | name_of_pip:'optional_Str_Varible'">

        <h2>Key Value = {{posts[myPost]}} 

        <h2>Key Name = {{myPost}} </h2>

      </ion-item>
   </ion-list>  

to make the API call it looks like you need to import HttpModule into app.module.ts

import { HttpModule } from '@angular/http';
 .
 .  
 imports: [
BrowserModule,
HttpModule,

and you need Http in the page you make the call from

import {Http} from '@angular/http';

When making the API call you seem to be able to get to the children data (the objects or arrays within the array) 2 different ways, either seem to work

either during the call

this.http.get('https://SomeWebsiteWithAPI').map(res => res.json().anyChildren.OrSubChildren).subscribe(
        myData => {

or when you assign the data to your local variable

posts: Array<String>;    
this.posts = myData['anyChildren'];

(not sure if that variable needs to be an Array String, but thats what i have it at now. It may work as a more generic variable)

And final note, it was not necessary to use the inbuilt JSON library however you may find these 2 calls handy for converting from an object to a string and vica versa

        var stringifiedData = JSON.stringify(this.movies);                  
        console.log("**mResults in Stringify");
        console.log(stringifiedData);

        var mResults = JSON.parse(<string>stringifiedData);
        console.log("**mResults in a JSON");
        console.log(mResults);

I hope this compilation of info helps someone out.

It's an implicit conversion to bool. I.e. wherever implicit conversions are allowed, your class can be converted to bool by calling that method.

You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.

When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.

Reference:
C++03 standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:

• To move the definition to the .h file
• Add explicit instantiations in the .cpp file.
• #include the .cpp file defining the template at the .cpp file using the template.

Each of them have their pros and cons,

Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.

Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.

While including cpp files is confusing at the same time shares the problems of both above approaches.

I find first method the easiest to follow and implement and hence advocte using it.

There is a nice open source Git stack called Git Blit. It is available for different platform and in different packages. You can also easily deploy it to your existing Tomcat or any other servlet container. Take a look at Setup git server on windows in few clicks tutorial for more details, it will take you around 10 minutes to get basic setup.

You'd use a self-join on a table that "refers" to itself - e.g. a table of employees where managerid is a foreign-key to employeeid on that same table.

Example:

SELECT E.name, ME.name AS manager
FROM dbo.Employees E
LEFT JOIN dbo.Employees ME
ON ME.employeeid = E.managerid

Using Sourcetree | The easiest way.

• First, checkout the branch that you want to take the specific commit to make a new branch.
• Then look at the toolbar, select Repository > Branch ... the shortcut is Command + Shift + B.
• And select the specific commit you want to take. And give a new branch name then create a branch!

If you want to open inside the app itself instead of leaving the app you can import SafariServices and work it out.

import UIKit
import SafariServices

let url = URL(string: "https://www.google.com")
let vc = SFSafariViewController(url: url!)
present(vc, animated: true, completion: nil)

Flushing the output buffers:

printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is

or

fprintf(fd, "Buffered, will be flushed");
fflush(fd);  //Prints to a file

Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf() it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.

Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf(), so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.

I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf() is an expensive operation (which is why it doesn't by default flush the buffer).

As far as flushing the input buffer (stdin), you should not do that. Flushing stdin is undefined behavior according to the C11 standard §7.21.5.2 part 2:

If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.

On some systems, Linux being one as you can see in the man page for fflush(), there's a defined behavior but it's system dependent so your code will not be portable.

Now if you're worried about garbage "stuck" in the input buffer you can use fpurge() on that. See here for more on fflush() and fpurge()

To fix the issue

Pressing ctrl+M causes the ? Tab key to move focus instead of inserting a ? Tab character.
Turn it off by pressing the shortcut again.

To disable the shortcut

1. Open "Keyboard Shortcuts" with ctrl+K, then ctrl+S.
   Or go to File > Preferences > Keyboard Shortcuts.
2. Search for toggle tab key moves focus.
3. Right Click, Remove Keybinding.

apparently on sql server 2008 r2 64bit, with long running query from IIS the kill spid doesn't seem to work, the query just gets restarted again and again. and it seems to be reusing the spid's. the query is causing sql server to take like 35% cpu constantly and hang the website. I'm guessing bc/ it can't respond to other queries for logging in

The solution that work for me is the following:

1. Delete .metadata folder
2. Restart eclipse

you can use -f option to force delete the containers .

sudo docker rmi -f training/webapp

You may stop the containers using sudo docker stop training/webapp before deleting

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

                 + response.getStatus());

        String output = response.getEntity(String.class);

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

This thread can help you: Passing request parameters as UTF-8 encoded strings

Basically:

request.setCharacterEncoding("UTF-8");
String login = request.getParameter("login");
String password = request.getParameter("password");

Or you use javascript on jsp file:

var userInput = $("#myInput").val();            
var encodedUserInput = encodeURIComponent(userInput);
$("#hiddenImput").val(encodedUserInput);

and after recover on class:

String parameter = URLDecoder.decode(request.getParameter("hiddenImput"), "UTF-8");

To upgrade Ruby with rbenv: Per the rbenv README

• Update first: brew upgrade rbenv ruby-build
• See list of Ruby versions: versions available: rbenv install -l
• Install: rbenv install <selected version>

There's a far more simpler solution to tackle this.

The reason why you get ValueError: Index contains duplicate entries, cannot reshape is because, once you unstack "Location", then the remaining index columns "id" and "date" combinations are no longer unique.

You can avoid this by retaining the default index column (row #) and while setting the index using "id", "date" and "location", add it in "append" mode instead of the default overwrite mode.

So use,

e.set_index(['id', 'date', 'location'], append=True)

Once this is done, your index columns will still have the default index along with the set indexes. And unstack will work.

Let me know how it works out.

Please use this command

git rm -rf --cached .
git add .

Sometimes .gitignore files don't work even though they're correct. The reason Git ignores files is that they are not added to the repository. If you added a file that you want to ignore before, it will be tracked by Git, and any skipping matching rules will be skipped. Git does this because the file is already part of the repository.

Java Library Description

Although, the question is fairly old, I'm adding info not present in other answers.

The OP is using stop() to stop the current animation as soon as the event completes. However, using the right mix of parameters with the function should help. eg. stop(true,true) or stop(true,false) as this affects the queued animations well.

The following link illustrates a demo that shows the different parameters available with stop() and how they differ from finish().

http://api.jquery.com/finish/

Although the OP had no issues using JqueryUI, this is for other users who may come across similar scenarios but cannot use JqueryUI/need to support IE7 and 8 too.

You could use replace to fix your string. The following will return everything before a "(" and also strip all leading and trailing whitespace. If the string starts with a "(" it will just leave it as is.

str = "manchester united (with nice players)"
matched = str.match(/.*(?=\()/)
str.replace(matched[0].strip) if matched

I got the same problem, but i find the answer in this page! it works for me, you can try it.

iconv -f cp936 -t utf-8 

Think your should look around: datetime.astimezone()

http://docs.python.org/library/datetime.html#datetime.datetime.astimezone

Also see pytz module - it's quite easy to use -- as example:

eastern = timezone('US/Eastern')

http://pytz.sourceforge.net/

Example:

from datetime import datetime
import pytz
from tzlocal import get_localzone # $ pip install tzlocal

utc_dt = datetime(2009, 7, 10, 18, 44, 59, 193982, tzinfo=pytz.utc)
print(utc_dt.astimezone(get_localzone())) # print local time
# -> 2009-07-10 14:44:59.193982-04:00

var data=(from t in db.your tableName(t1) 
          join s in db.yourothertablename(t2) on t1.fieldname equals t2.feldname
          (where condtion)).tolist();

You need to specify the location of the other scripts, there is no other way around it. I'd recommend a configurable variable at the top of your script:

#!/bin/bash
installpath=/where/your/scripts/are

. $installpath/incl.sh

echo "The main script"

Alternatively, you can insist that the user maintain an environment variable indicating where your program home is at, like PROG_HOME or somesuch. This can be supplied for the user automatically by creating a script with that information in /etc/profile.d/, which will be sourced every time a user logs in.

As others have said, # coding: specifies the encoding the source file is saved in. Here are some examples to illustrate this:

A file saved on disk as cp437 (my console encoding), but no encoding declared

b = 'über'
u = u'über'
print b,repr(b)
print u,repr(u)

Output:

  File "C:\ex.py", line 1
SyntaxError: Non-ASCII character '\x81' in file C:\ex.py on line 1, but no
encoding declared; see http://www.python.org/peps/pep-0263.html for details

Output of file with # coding: cp437 added:

über '\x81ber'
über u'\xfcber'

At first, Python didn't know the encoding and complained about the non-ASCII character. Once it knew the encoding, the byte string got the bytes that were actually on disk. For the Unicode string, Python read \x81, knew that in cp437 that was a ü, and decoded it into the Unicode codepoint for ü which is U+00FC. When the byte string was printed, Python sent the hex value 81 to the console directly. When the Unicode string was printed, Python correctly detected my console encoding as cp437 and translated Unicode ü to the cp437 value for ü.

Here's what happens with a file declared and saved in UTF-8:

++ber '\xc3\xbcber'
über u'\xfcber'

In UTF-8, ü is encoded as the hex bytes C3 BC, so the byte string contains those bytes, but the Unicode string is identical to the first example. Python read the two bytes and decoded it correctly. Python printed the byte string incorrectly, because it sent the two UTF-8 bytes representing ü directly to my cp437 console.

Here the file is declared cp437, but saved in UTF-8:

++ber '\xc3\xbcber'
++ber u'\u251c\u255dber'

The byte string still got the bytes on disk (UTF-8 hex bytes C3 BC), but interpreted them as two cp437 characters instead of a single UTF-8-encoded character. Those two characters where translated to Unicode code points, and everything prints incorrectly.

Put the table in a container element that has

overflow:scroll; max-width:95vw;

or make the table fit to the screen and overflow:scroll all table cells.

I haven't used PowerShell V2's Send-MailMessage, but I have used System.Net.Mail.SMTPClient class in V1 to send messages to a Gmail account for demo purposes. This might be overkill, but I run an SMTP server on my Windows Vista laptop (see this link). If you're in an enterprise you will already have a mail relay server, and this step isn't necessary. Having an SMTP server I'm able to send email to my Gmail account with the following code:

$smtpmail = [System.Net.Mail.SMTPClient]("127.0.0.1")
$smtpmail.Send("[email protected]", "[email protected]", "Test Message", "Message via local SMTP")

The screen widths Bootstrap v3.x uses are as follows:

• Extra small devices Phones (<768px) / .col-xs-
• Small devices Tablets (=768px) / .col-sm-
• Medium devices Desktops (=992px) / .col-md-
• Large devices Desktops (=1200px) / .col-lg-

So, these are good to use and work well in practice.

There is an interesting Video on YouTube about this. Its from Linus Torwalds himself: Goolge Tech Talk: Linus Torvalds on git

You don't need css or html tricks for it. Font Awesome has built in class for it - fa-circle To stack multiple icons together you can use fa-stack class on the parent div

<span class="fa-stack fa-lg">
  <i class="fa fa-circle fa-stack-2x"></i>
  <i class="fa fa-flag fa-stack-1x fa-inverse"></i>
</span> 

//And we have now facebook icon inside circle:)

If the table has already been created:

First do:

ALTER TABLE `table1_name` ADD UNIQUE( `column_name`);

Then:

ALTER TABLE `table1_name` ADD FOREIGN KEY (`column_name`) REFERENCES `table2_name`(`column_name`);

Your code was compiled with Java Version 1.8 while it is being executed with Java Version 1.7 or below.

In your case it seems that two different Java installations are used, the newer to compile and the older to execute your code.

Try recompiling your code with Java 1.7 or upgrade your Java Plugin.

You can find Module Pattern JavaScript here http://www.sga.su/module-pattern-javascript/

In the latest GitHub client for Windows, if you have uncommitted changes, and choose to create a new branch.
It prompts you how to handle this exact scenario:

The same applies if you simply switch the branch too.

This simple method solved the problem for me: Copy the content of your dataset, open an empty Excel sheet, choose "Paste Special" -> "Values", and save. Import the new file instead.

(I tried all the existing solutions, and none worked for me. My old dataset appeared to have no missing values, space, special characters, or embedded formulas.)

If you add:

jquery.form.min.js

You can simply do this:

<script>
$('#myform').ajaxForm(function(response) {
  alert(response);
});

// this will register the AJAX for <form id="myform" action="some_url">
// and when you submit the form using <button type="submit"> or $('myform').submit(), then it will send your request and alert response
</script>

NOTE:

You could use simple $('FORM').serialize() as suggested in post above, but that will not work for FILE INPUTS... ajaxForm() will.

You do need to loop through it. C++ does not implement any simpler way to do this when you are dealing with primitive type arrays.

also see this answer: C++ check if element exists in array

By chance, is this occurring on a directory using OverlayFS (or some other special file system type)?

I just had this issue where my cross-compiled version of bash would use an internal implementation of getcwd which has issues with OverlayFS. I found information about this here:

It seems that this can be traced to an internal implementation of getcwd() in bash. When cross-compiled, it can't check for getcwd() use of malloc, so it is cautious and sets GETCWD_BROKEN and uses an internal implementation of getcwd(). This internal implementation doesn't seem to work well with OverlayFS.

http://permalink.gmane.org/gmane.linux.embedded.yocto.general/25204

You can configure and rebuild bash with bash_cv_getcwd_malloc=yes (if you're actually building bash and your C library does malloc a getcwd call).

Try this

html code

 <div id="refresh">
    <input type="text" />
    <input type="button" id="click" />
 </div>

jQuery code

 <script>
    $('#click').click(function(){
    var div=$('#refresh').html();
    $.ajax({
        url: '/path/to/file.php',
        type: 'POST',
        dataType: 'json',
        data: {param1: 'value1'},
    })
    .done(function(data) {
if(data.success=='ok'){
        $('#refresh').html(div);
}else{
// show errors.
}
    })
    .fail(function() {
        console.log("error");
    })
    .always(function() {
        console.log("complete");
    });
    });

</script>

php page code path=/path/to/file.php

<?php
   header('Content-Type: application/json');
   $done=true;
   if($done){
       echo json_encode(['success'=>'ok']);
   }
?>

There is no "unset" state for std::string, it is always set to something.

This works:

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

It will produce:

'abcdgxre'

You can also use a delimiter like a comma to produce:

'a,b,c,d,g,x,r,e'

By using:

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

What if onclick event is not directly on element, but from parent element? This should work:

$(".noclick").attr('onclick','').unbind('click');
$(".noclick").click(function(e){
    e.preventDefault();
    e.stopPropagation();
    return false;
});

One thing that might not always be obvious to some is that a cross join with an empty table (or result set) results in empty table (M x N; hence M x 0 = 0)

A full outer join will always have rows unless both M and N are 0.

You can tell the Java binary version by inspecting the first 8 bytes (or using an app that can).

The compiler itself doesn't, to the best of my knowledge, insert any identifying signature. I can't spot such a thing in the file VM spec class format anyway.

I did not modify your code for this solution, I wrote my own instead. My solution isn't quite what you asked for, but maybe you could build on it with existing knowledge. I commented the code as well so you know what exactly I'm doing with the changes.

As a solution to "avoid setting the height in JavaScript", I just made 'maxHeight' a parameter in the JS function called toggleHeight. Now it can be set in the HTML for each div of class expandable.

I'll say this up front, I'm not super experienced with front-end languages, and there's an issue where I need to click the 'Show/hide' button twice initially before the animation starts. I suspect it's an issue with focus.

The other issue with my solution is that you can actually figure out what the hidden text is without pressing the show/hide button just by clicking in the div and dragging down, you can highlight the text that's not visible and paste it to a visible space.

My suggestion for a next step on top of what I've done is to make it so that the show/hide button changes dynamically. I think you can figure out how to do that with what you already seem to know about showing and hiding text with JS.

Reading the comments, it seems that these solutions are not consistent across browsers. Decided then to think how I would have done this 10 years ago before the advent of jQuery and event function binding.

So here is my retro hipster solution:

<script type="text/javascript">
var _formConfirm_submitted = false;
</script>
<form name="frmConfirm" onsubmit="if( _formConfirm_submitted == false ){ _formConfirm_submitted = true;return true }else{ alert('your request is being processed!'); return false;  }" action="" method="GET">

<input type="submit" value="submit - but only once!"/>
</form>

The main point of difference is that I am relying on the ability to stop a form submitting through returning false on the submit handler, and I am using a global flag variable - which will make me go straight to hell!

But on the plus side, I cannot imagine any browser compatibility issues - hey, it would probably even work in Netscape!

            ex2 = ex2.InnerException;
        }
        Page.RegisterStartupScript("UserMsg", "<script>alert('Sending Failed...');if(alert){ window.location='SendMail.aspx';}</script>");
    }
}

You can do something like this:

public class Example
{
    public String name;
    public String location;

    public String[] getExample()
    {
        String ar[] = new String[2];
        ar[0]= name;
        ar[1] =  location;
        return ar; //returning two values at once
    }
}

adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

This assumes your /system is yaffs2 and that it's at /dev/block/mtdblock3 the easier/better way to do this on most Android phones is:

adb shell
su
mount -o remount,rw /system

Done. This just says remount /system read-write, you don't have to specify filesystem or mount location.

This could be done using reshape. It is possible with dplyr though.

  colnames(df) <- gsub("\\.(.{2})$", "_\\1", colnames(df))
  colnames(df)[2] <- "Date"
  res <- reshape(df, idvar=c("id", "Date"), varying=3:8, direction="long", sep="_")
  row.names(res) <- 1:nrow(res)
  
   head(res)
  #  id       Date time       Q3.2       Q3.3
  #1  1 2009-01-01    1  1.3709584  0.4554501
  #2  2 2009-01-02    1 -0.5646982  0.7048373
  #3  3 2009-01-03    1  0.3631284  1.0351035
  #4  4 2009-01-04    1  0.6328626 -0.6089264
  #5  5 2009-01-05    1  0.4042683  0.5049551
  #6  6 2009-01-06    1 -0.1061245 -1.7170087

Or using dplyr

  library(tidyr)
  library(dplyr)
  colnames(df) <- gsub("\\.(.{2})$", "_\\1", colnames(df))

  df %>%
     gather(loop_number, "Q3", starts_with("Q3")) %>% 
     separate(loop_number,c("L1", "L2"), sep="_") %>% 
     spread(L1, Q3) %>%
     select(-L2) %>%
     head()
  #  id       time       Q3.2       Q3.3
  #1  1 2009-01-01  1.3709584  0.4554501
  #2  1 2009-01-01  1.3048697  0.2059986
  #3  1 2009-01-01 -0.3066386  0.3219253
  #4  2 2009-01-02 -0.5646982  0.7048373
  #5  2 2009-01-02  2.2866454 -0.3610573
  #6  2 2009-01-02 -1.7813084 -0.7838389

Update

With new version of tidyr, we can use pivot_longer to reshape multiple columns. (Using the changed column names from gsub above)

library(dplyr)
library(tidyr)
df %>% 
    pivot_longer(cols = starts_with("Q3"), 
          names_to = c(".value", "Q3"), names_sep = "_") %>% 
    select(-Q3)
# A tibble: 30 x 4

NOTE: Values are different because there was no set seed in creating the input dataset

ArrayList: The ArrayList class extends AbstractList and implements the List interface and RandomAccess (marker interface). ArrayList supports dynamic arrays that can grow as needed. It gives us first iteration over elements.

LinkedList: A LinkedList is ordered by index position, like ArrayList, except that the elements are doubly-linked to one another. This linkage gives you new methods (beyond what you get from the List interface) for adding and removing from the beginning or end, which makes it an easy choice for implementing a stack or queue. Keep in mind that a LinkedList may iterate more slowly than an ArrayList, but it's a good choice when you need fast insertion and deletion. As of Java 5, the LinkedList class has been enhanced to implement the java.util.Queue interface. As such, it now supports the common queue methods: peek (), poll (), and offer ().

def remove_prefix(str, prefix):
    if str.startswith(prefix):
        return str[len(prefix):]
    else:
        return str

As an aside note, str is a bad name for a variable because it shadows the str type.

Call GoogleMap.setMyLocationEnabled(true) in your Activity, and add this 2 lines code in the Manifest:

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

The iPhone SDK agreement is also rather vague about whether you're even allowed to run scripting languages (outside of a WebView's Javascript). My reading is that it is OK - as long as none of the scripts you execute are downloaded from the network (so pre-installed and user-edited scripts seem to be OK).

IANAL etc etc.

Alternative for @LadislavMrnka answer. This if for Entity Framework 6.2.0.

If you have a specific DbSet and an item that needs to be either updated or created:

var name = getNameFromService();

var current = _dbContext.Names.Find(name.BusinessSystemId, name.NameNo);
if (current == null)
{
    _dbContext.Names.Add(name);
}
else
{
    _dbContext.Entry(current).CurrentValues.SetValues(name);
}
_dbContext.SaveChanges();

However this can also be used for a generic DbSet with a single primary key or a composite primary key.

var allNames = NameApiService.GetAllNames();
GenericAddOrUpdate(allNames, "BusinessSystemId", "NameNo");

public virtual void GenericAddOrUpdate<T>(IEnumerable<T> values, params string[] keyValues) where T : class
{
    foreach (var value in values)
    {
        try
        {
            var keyList = new List<object>();

            //Get key values from T entity based on keyValues property
            foreach (var keyValue in keyValues)
            {
                var propertyInfo = value.GetType().GetProperty(keyValue);
                var propertyValue = propertyInfo.GetValue(value);
                keyList.Add(propertyValue);
            }

            GenericAddOrUpdateDbSet(keyList, value);
            //Only use this when debugging to catch save exceptions
            //_dbContext.SaveChanges();
        }
        catch
        {
            throw;
        }
    }
    _dbContext.SaveChanges();
}

public virtual void GenericAddOrUpdateDbSet<T>(List<object> keyList, T value) where T : class
{
    //Get a DbSet of T type
    var someDbSet = Set(typeof(T));

    //Check if any value exists with the key values
    var current = someDbSet.Find(keyList.ToArray());
    if (current == null)
    {
        someDbSet.Add(value);
    }
    else
    {
        Entry(current).CurrentValues.SetValues(value);
    }
}

Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.

Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).

Django 1.4.1

Python 2.7.3

#Model
class MonthEnd(models.Model):
    report = models.FileField(db_index=True, upload_to='not_used')

import csv
from os.path import join

#build and store the file
def write_csv():
    path = join(settings.MEDIA_ROOT, 'files', 'month_end', 'report.csv')
    f = open(path, "w+b")

    #wipe the existing content
    f.truncate()

    csv_writer = csv.writer(f)
    csv_writer.writerow(('col1'))

    for num in range(3):
        csv_writer.writerow((num, ))

    month_end_file = MonthEnd()
    month_end_file.report.name = path
    month_end_file.save()

from my_app.models import MonthEnd

#serve it up as a download
def get_report(request):
    month_end = MonthEnd.objects.get(file_criteria=criteria)

    response = HttpResponse(month_end.report, content_type='text/plain')
    response['Content-Disposition'] = 'attachment; filename=report.csv'

    return response

Setting timestamps to false means you are going to lose both created_at and updated_at whereas you could set both of the keys in your model.

Case 1:

You have created_at column but not update_at you could simply set updated_at to false in your model

class ABC extends Model {

const UPDATED_AT = null;

Case 2:

You have both created_at and updated_at columns but with different column names

You could simply do:

class ABC extends Model {

const CREATED_AT = 'name_of_created_at_column';
const UPDATED_AT = 'name_of_updated_at_column';

Finally ignoring timestamps completely:

class ABC extends Model {

public $timestamps = false;

Basically, you want to find a balance between two variables: the number of clusters (k) and the average variance of the clusters. You want to minimize the former while also minimizing the latter. Of course, as the number of clusters increases, the average variance decreases (up to the trivial case of k=n and variance=0).

As always in data analysis, there is no one true approach that works better than all others in all cases. In the end, you have to use your own best judgement. For that, it helps to plot the number of clusters against the average variance (which assumes that you have already run the algorithm for several values of k). Then you can use the number of clusters at the knee of the curve.

The answer by Agalin is already great and I just want to explain it in a step by step format for a novice like myself:

• find your Python version by python --version mine is 3.7.3 for example
• the easiest way to check either you have 64 or 32 Python just open it in the terminal:

• find the appropriate .whl file from here, for example mine is PyAudio-0.2.11-cp37-cp37m-win_amd64.whl, and download it.
• go to the folder where it is downloaded for example cd C:\Users\foobar\Downloads
• install the .whl file with pip for example in my case:

pip install PyAudio-0.2.11-cp37-cp37m-win_amd64.whl

Please try this:

DELETE FROM `table` WHERE id >=163 and id<= 265

You can either do

SELECT name
FROM table2
WHERE name NOT IN
    (SELECT name 
     FROM table1)

or

SELECT name 
FROM table2 
WHERE NOT EXISTS 
    (SELECT * 
     FROM table1 
     WHERE table1.name = table2.name)

See this question for 3 techniques to accomplish this

As I am not allowed to comment yet:

For CentOS 7 I needed to activate the EnvironmentFile within "docker.service" like it is described here: Control and configure Docker with systemd.

Edit: I am adding my solution as stated out by Nilesh. I needed to open "/etc/systemd/system/docker.service" and I had to add within the section

[Service]

EnvironmentFile=-/etc/sysconfig/docker

Only then was the file "etc/sysconfig/docker" loaded on my system.

an easy way with out much redundancy.

    Dim fso As Object
    Set fso = CreateObject("Scripting.FileSystemObject")

    Dim Fileout As Object
    Set Fileout = fso.CreateTextFile("C:\your_path\vba.txt", True, True)
    Fileout.Write "your string goes here"
    Fileout.Close

Just to add one case to unutbu's list.

One of the biggest practical differences for me of numpy ndarrays compared to numpy matrices or matrix languages like matlab, is that the dimension is not preserved in reduce operations. Matrices are always 2d, while the mean of an array, for example, has one dimension less.

For example demean rows of a matrix or array:

with matrix

>>> m = np.mat([[1,2],[2,3]])
>>> m
matrix([[1, 2],
        [2, 3]])
>>> mm = m.mean(1)
>>> mm
matrix([[ 1.5],
        [ 2.5]])
>>> mm.shape
(2, 1)
>>> m - mm
matrix([[-0.5,  0.5],
        [-0.5,  0.5]])

with array

>>> a = np.array([[1,2],[2,3]])
>>> a
array([[1, 2],
       [2, 3]])
>>> am = a.mean(1)
>>> am.shape
(2,)
>>> am
array([ 1.5,  2.5])
>>> a - am #wrong
array([[-0.5, -0.5],
       [ 0.5,  0.5]])
>>> a - am[:, np.newaxis]  #right
array([[-0.5,  0.5],
       [-0.5,  0.5]])

I also think that mixing arrays and matrices gives rise to many "happy" debugging hours. However, scipy.sparse matrices are always matrices in terms of operators like multiplication.

here is the example using Pure JavaScript

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

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

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

One liner:

System.IO.File.WriteAllText(@"D:\file.txt", content);

It creates the file if it doesn't exist and overwrites it if it exists. Make sure you have appropriate privileges to write to the location, otherwise you will get an exception.

https://msdn.microsoft.com/en-us/library/ms143375%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396

Write string to text file and ensure it always overwrites the existing content.

If you want to use @Html.EditorFor() you have to use jQuery ui and update your Asp.net Mvc to 5.2.6.0 with NuGet Package Manager.

@Html.EditorFor(m => m.EntryDate, new { htmlAttributes = new { @class = "datepicker" } })

@section Scripts {

@Scripts.Render("~/bundles/jqueryval")

<script>

    $(document).ready(function(){

      $('.datepicker').datepicker();

     });

Since you've already mentioned the Ordered Test functionality that the Visual Studio testing framework supplies, I'll ignore that. You also seem to be aware that what you're trying to accomplish in order to test this Static Class is a "bad idea", so I'll ignore that to.

Instead, lets focus on how you might actually be able to guarantee that your tests are executed in the order you want. One option (as supplied by @gaog) is "one test method, many test functions", calling your test functions in the order that you want from within a single function marked with the TestMethod attribute. This is the simplest way, and the only disadvantage is that the first test function to fail will prevent any of the remaining test functions from executing.

With your description of the situation, this is the solution I would suggest you use.

If the bolded part is a problem for you, you can accomplish an ordered execution of isolated tests by leveraging the in built data driven test functionality. Its more complicated and feels a bit dirty, but it gets the job done.

In short, you define a data source (like a CSV file, or a database table) that controls the order in which you need to run your tests, and names of the functions that actually contain the test functionality. You then hook that data source into a data driven test, use the sequential read option, and execute your functions, in the order you want, as individual tests.

[TestClass]
public class OrderedTests
{
    public TestContext TestContext { get; set; }

    private const string _OrderedTestFilename = "TestList.csv";

    [TestMethod]
    [DeploymentItem(_OrderedTestFilename)]
    [DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", _OrderedTestFilename, _OrderedTestFilename, DataAccessMethod.Sequential)]
    public void OrderedTests()
    {
        var methodName = (string)TestContext.DataRow[0];
        var method = GetType().GetMethod(methodName);
        method.Invoke(this, new object[] { });
    }

    public void Method_01()
    {
        Assert.IsTrue(true);
    }

    public void Method_02()
    {
        Assert.IsTrue(false);
    }

    public void Method_03()
    {
        Assert.IsTrue(true);
    }
}

In my example, I have a supporting file called TestList.csv, which gets copied to output. It looks like this:

TestName
Method_01
Method_02
Method_03

Your tests will be executed in the order that you specified, and in normal test isolation (i.e. if one fails, the rest still get executed, but sharing static classes).

The above is really only the basic idea, if I were to use it in production I would generate the test function names and their order dynamically before the test is run. Perhaps by leveraging PriorityAttribute you found and some simple reflection code to extract the test methods in the class and order them appropriately, then write that order to the data source.

Add this code structure to your page code

<?php
echo '<label>Admission Year:</label><br><select name="admission_year" data-component="date">';
for($year=1900; $year<=date('Y'); $year++){
echo '<option value="'.$year.'">'.$year.'</option>';
}
?>

It works perfectly and can be reverse engineered

<?php
echo '<label>Admission Year:</label><br><select name="admission_year" data-component="date">';
for($year=date('Y'); $year>=1900; $year++){
echo '<option value="'.$year.'">'.$year.'</option>';
}
?>

With this you are good to go.

To do it the ASP.NET way:

<asp:TextBox ID="txtBox1" TextMode="Password" runat="server" />

If box-sizing is not an option, another way to do this is just to make it a child of the sized element.

Demo

CSS

.box {
  width: 100px;
  height: 100px;
  display: inline-block;
  margin-right: 5px;
}
.border {
  border: 1px solid;
  display: block;
}
.medium { border-width: 10px; }
.large  { border-width: 25px; }

HTML

<div class="box">
  <div class="border small">A</div>
</div>
<div class="box">
  <div class="border medium">B</div>
</div>
<div class="box">
  <div class="border large">C</div>
</div>

From the man read:

#include <unistd.h>
ssize_t read(int fd, void *buf, size_t count);

Input parameters:

• int fd file descriptor is an integer and not a file pointer. The file descriptor for stdin is 0

• void *buf pointer to buffer to store characters read by the read function

• size_t count maximum number of characters to read

So you can read character by character with the following code:

char buf[1];

while(read(0, buf, sizeof(buf))>0) {
   // read() here read from stdin charachter by character
   // the buf[0] contains the character got by read()
   ....
}

System.Threading.Thread.Sleep(
    (int)System.TimeSpan.FromSeconds(3).TotalMilliseconds);

Or with using statements:

Thread.Sleep((int)TimeSpan.FromSeconds(2).TotalMilliseconds);

I prefer this to 1000 * numSeconds (or simply 3000) because it makes it more obvious what is going on to someone who hasn't used Thread.Sleep before. It better documents your intent.

If you are going to be adding lots of items, consider deriving your own class from ObservableCollection and adding items to the protected Items member - this won't raise events in observers. When you are done you can raise the appropriate events:

public class BulkUpdateObservableCollection<T> : ObservableCollection<T>
{
    public void AddRange(IEnumerable<T> collection)
    {
        foreach (var i in collection) Items.Add(i);
        OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset));
        OnPropertyChanged(new PropertyChangedEventArgs("Count"));
    }
 }

When adding many items to an ObservableCollection that is already bound to a UI element (such as LongListSelector) this can make a massive performance difference.

Prior to adding the items, you could also ensure you have enough space, so that the list isn't continually being expanded by implementing this method in the BulkObservableCollection class and calling it prior to calling AddRange:

    public void IncreaseCapacity(int increment)
    {
        var itemsList = (List<T>)Items;
        var total = itemsList.Count + increment;
        if (itemsList.Capacity < total)
        {
            itemsList.Capacity = total;
        }
    }

Probably depending on the XML feed you may/may not need to use __toString(); I had to use the __toString() otherwise it is returning the string inside an SimpleXMLElement. Maybe I need to drill down the object further ...

I think it will be perfect solution:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <!-- Other views -->
    <Space
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <!-- Target view below -->
    <View
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

</LinearLayout>

Here's one way which will piss off everyone but work pretty well. In tests run:

ln -s ../components components

Then just import components like you normally would.

My original reply was factually incorrect and I'm glad it was removed. The code below will work under the following conditions a) you know that nobody else modified the sequence b) the sequence was modified by your session. In my case, I encountered a similar issue where I was calling a procedure which modified a value and I'm confident the assumption is true.

SELECT mysequence.CURRVAL INTO v_myvariable FROM DUAL;

Sadly, if you didn't modify the sequence in your session, I believe others are correct in stating that the NEXTVAL is the only way to go.

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

In Oracle query

select a.x
            ,(select b.y || ',' || b.z
                from   b
                where  b.v = a.v
                and    rownum = 1) as multple_columns
from   a

can be transformed to:

select a.x, b1.y, b1.z
from   a, b b1
where  b1.rowid = (
       select b.rowid
       from   b
       where  b.v = a.v
       and    rownum = 1
)

Is useful when we want to prevent duplication for table A. Similarly, we can increase the number of tables:

.... where (b1.rowid,c1.rowid) = (select b.rowid,c.rowid ....

Following the JSON-P 1.0 specs (JSR-353) a more current solution for a given JsonStructure (JsonObject or JsonArray) could look like this:

import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;

import javax.json.Json;
import javax.json.JsonStructure;
import javax.json.JsonWriter;
import javax.json.JsonWriterFactory;
import javax.json.stream.JsonGenerator;

public class PrettyJson {

    private static JsonWriterFactory FACTORY_INSTANCE;

    public static String toString(final JsonStructure status) {

        final StringWriter stringWriter = new StringWriter();

        final JsonWriter jsonWriter = getPrettyJsonWriterFactory()
                .createWriter(stringWriter);

        jsonWriter.write(status);
        jsonWriter.close();

        return stringWriter.toString();
    }

    private static JsonWriterFactory getPrettyJsonWriterFactory() {
        if (null == FACTORY_INSTANCE) {
            final Map<String, Object> properties = new HashMap<>(1);
            properties.put(JsonGenerator.PRETTY_PRINTING, true);
            FACTORY_INSTANCE = Json.createWriterFactory(properties);
        }
        return FACTORY_INSTANCE;
    }

}

You can use OR() to group expressions (as well as AND()):

=IF(OR(condition1, condition2), true, false)

=IF(AND(condition1, condition2), true, false)

So if you wanted to test for "cat" and "22":

=IF(AND(SEARCH("cat",a1),SEARCH("22",a1)),"cat and 22","none")

For me, the answer was to add two 'Content Roots' in 'File' -> 'Project Structure' -> 'Modules' (in IntelliJ):

1. YourPath\spark-2.2.1-bin-hadoop2.7\python
2. YourPath\spark-2.2.1-bin-hadoop2.7\python\lib\py4j-0.10.4-src.zip

select Id, StartDate,
Case IsNull (StartDate , '01/01/1800')
When '01/01/1800' then
  'Awaiting'
Else
  'Approved'
END AS StartDateStatus

In your case IF you want to go with foreach loop than

$sum = 0;
foreach($group as $key => $value) {
   $sum += $value; 
}
echo $sum;

But if you want to go with direct sum of array than look on below for your solution :

$total = array_sum($group);

for only sum of array looping is time wasting.

http://php.net/manual/en/function.array-sum.php

array_sum — Calculate the sum of values in an array

<?php
$a = array(2, 4, 6, 8);
echo "sum(a) = " . array_sum($a) . "\n";

$b = array("a" => 1.2, "b" => 2.3, "c" => 3.4);
echo "sum(b) = " . array_sum($b) . "\n";
?>

The above example will output:

sum(a) = 20
sum(b) = 6.9

Instructions

First, insert these lines wherever you want within your newsletter code. Then:

1. Change "INSERT URL" to whatever website holds the shared content.
2. Change "INSERT TITLE" to the title of the article.
3. Change "INSERT SUMMARY" to a short summary of the article.
4. Change "INSERT IMAGE URL" to an image that will be shared with the rest of the content.
5. Change "INSERT DOMAIN NAME" to your domain name.
6. Change "INSERT PUBLISHERID" to your publisher ID (if you have an account, if not, remove "[INSERT PUBLISHERID]" or sign up!)

If you are using this on an email newsletter, make sure you add our sharing buttons to the destination page. This will ensure that you get complete sharing analytics for your page. Make sure you replace "INSERT PUBLISHERID" with your own.

I had the same problem but from IIS in visual studio, I went to project properties -> Web -> and project url change http to https

A free app named SqlTableZip will get the job done. Basically, you write any query (which, of course can also be [select * from table]) and the app creates a compressed file with all the data, which can be restored later.

Link: http://www.doccolabs.com/products_sqltablezip.html

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

Put simply

• & means the address-of, you will see that in placeholders for functions to modify the parameter variable as in C, parameter variables are passed by value, using the ampersand means to pass by reference.
• * means the dereference of a pointer variable, meaning to get the value of that pointer variable.

int foo(int *x){
   *x++;
}

int main(int argc, char **argv){
   int y = 5;
   foo(&y);  // Now y is incremented and in scope here
   printf("value of y = %d\n", y); // output is 6
   /* ... */
}

The above example illustrates how to call a function foo by using pass-by-reference, compare with this

int foo(int x){
   x++;
}

int main(int argc, char **argv){
   int y = 5;
   foo(y);  // Now y is still 5
   printf("value of y = %d\n", y); // output is 5
   /* ... */
}

Here's an illustration of using a dereference

int main(int argc, char **argv){
   int y = 5;
   int *p = NULL;
   p = &y;
   printf("value of *p = %d\n", *p); // output is 5
}

The above illustrates how we got the address-of y and assigned it to the pointer variable p. Then we dereference p by attaching the * to the front of it to obtain the value of p, i.e. *p.

In Command line we can check our installed ng version.

ng -v OR ng --version OR ng version

This will give you like this :

 _                      _                 ____ _     ___

   / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
  / ? \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |
 / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |

For completeness, one other way is to clear the softspace value after performing the write.

import sys
print "hello",
sys.stdout.softspace=0
print "world",
print "!"

prints helloworld !

Using stdout.write() is probably more convenient for most cases though.

I think your question isn't quite clear. There are several answers here on how to catch the data coming into a Linux's serial port, but perhaps your problem is the other way around?

If you need to catch the data coming out of a Linux's serial port and send it to a server, there are several little hardware gizmos that can do this, starting with the simple serial print server such as this Lantronix gizmo.

No, I'm not affiliated with Lantronix in any way.

If you're looking to simply reduce or increase the width of Bootstrap's input elements to your liking, I would use max-width in the CSS.

Here is a very simple example I created:

    <form style="max-width:500px">

    <div class="form-group"> 
    <input type="text" class="form-control" id="name" placeholder="Name">
    </div>

    <div class="form-group">
    <input type="email" class="form-control" id="email" placeholder="Email Address">
    </div>

    <div class="form-group">
    <textarea class="form-control" rows="5" placeholder="Message"></textarea>
    </div>   

    <button type="submit" class="btn btn-primary">Submit</button>
    </form>

I've set the whole form's maximum width to 500px. This way you won't need to use any of Bootstrap's grid system and it will also keep the form responsive.

You can use WebClient to download the html for any url. Once you have the html, you can use a third-party library like HtmlAgilityPack to lookup values in the html as in below code -

public static string GetInnerHtmlFromDiv(string url)
    {
        string HTML;
        using (var wc = new WebClient())
        {
            HTML = wc.DownloadString(url);
        }
        var doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(HTML);
        
        HtmlNode element = doc.DocumentNode.SelectSingleNode("//div[@id='<div id here>']");
        if (element != null)
        {
            return element.InnerHtml.ToString();
        }   
        return null;            
    }

I was trying to map an IEnumerable to an object. This is way I got this error. Maybe it helps.

Or, alternatively, you could use Operator module. More detailed information is here Python docs

import operator
import numpy as np
import pandas as pd
np.random.seed(0)
df = pd.DataFrame(np.random.randn(5,3), columns=list('ABC'))
df.loc[operator.or_(df.C > 0.25, df.C < -0.25)]

          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.4438

Which of these three approaches is most suited for the task?

Depends on the task :-) To match exactly all Latin characters and their accented versions, the Unicode ranges probably provide the best solution. They might be extended to all non-whitespace characters, which could be done using the \S character class.

I'm forcing a field in a UI to match the format: last_name, first_name (last [comma space] first)

The most basic problem I'm seeing here are not diacritics, but whitespaces. There are a few names that consist of multiple words, e.g. for titles. So you should go with the most generic, that is allowing everything but the comma that distinguishes first from last name:

/[^,]+,\s[^,]+/

But your second solution with the . character class is just as fine, you only might need to care about multiple commata then.

This is an error caused by importing the wrong module react from 'react' how about you try this: 1st

import React , { Component}  from 'react';

2nd Or you can try this as well:

import React from 'react';
import { render   }  from 'react-dom';

class TechView extends React.Component {

    constructor(props){
       super(props);
       this.state = {
           name:'Gopinath',
       }
    }
    render(){
        return(
            <span>hello Tech View</span>
        );
    }
}

export default TechView;

You have to arrange for a distinct copy of "i" to be present for each of the timeout functions.

function doSetTimeout(i) {
  setTimeout(function() { alert(i); }, 100);
}

for (var i = 1; i <= 2; ++i)
  doSetTimeout(i);

If you don't do something like this (and there are other variations on this same idea), then each of the timer handler functions will share the same variable "i". When the loop is finished, what's the value of "i"? It's 3! By using an intermediating function, a copy of the value of the variable is made. Since the timeout handler is created in the context of that copy, it has its own private "i" to use.

edit — there have been a couple of comments over time in which some confusion was evident over the fact that setting up a few timeouts causes the handlers to all fire at the same time. It's important to understand that the process of setting up the timer — the calls to setTimeout() — take almost no time at all. That is, telling the system, "Please call this function after 1000 milliseconds" will return almost immediately, as the process of installing the timeout request in the timer queue is very fast.

Thus, if a succession of timeout requests is made, as is the case in the code in the OP and in my answer, and the time delay value is the same for each one, then once that amount of time has elapsed all the timer handlers will be called one after another in rapid succession.

If what you need is for the handlers to be called at intervals, you can either use setInterval(), which is called exactly like setTimeout() but which will fire more than once after repeated delays of the requested amount, or instead you can establish the timeouts and multiply the time value by your iteration counter. That is, to modify my example code:

function doScaledTimeout(i) {
  setTimeout(function() {
    alert(i);
  }, i * 5000);
}

(With a 100 millisecond timeout, the effect won't be very obvious, so I bumped the number up to 5000.) The value of i is multiplied by the base delay value, so calling that 5 times in a loop will result in delays of 5 seconds, 10 seconds, 15 seconds, 20 seconds, and 25 seconds.

Update

Here in 2018, there is a simpler alternative. With the new ability to declare variables in scopes more narrow than functions, the original code would work if so modified:

for (let i = 1; i <= 2; i++) {
    setTimeout(function() { alert(i) }, 100);
}

The let declaration, unlike var, will itself cause there to be a distinct i for each iteration of the loop.

In case you are working with a column with string values, you can use THE VERY USEFUL function series.str.isnumeric() like:

a = pd.Series(['hi','hola','2.31','288','312','1312', '0,21', '0.23'])

What i do is to copy that column to new column, and do a str.replace('.','') and str.replace(',','') then i select the numeric values. and:

a = a.str.replace('.','')
a = a.str.replace(',','') 
a.str.isnumeric()

Out[15]: 0 False 1 False 2 True 3 True 4 True 5 True 6 True 7 True dtype: bool

Good luck all!

I think my answer will help more. I faced this error also. Then I deleted specific migration file and tried to recreate by php artisan.

But before get this point 1 or 2 days ago while I was watching laracast videos about migation, I was thinking rollback and migrate specific table. For some reason I deleted specific migration file and tried recreate but doing so I got:

[ErrorException] include(C:\wamp64\www\laraveldeneme\vendor\composer/../../database/migrations/2017_01_09_082715_create_articles_table.php): failed to open stream: No such file or directory

When I check that file I saw the line below at top of array in the autoload_classmap.php file:

'CreateArticlesTable'=>$baseDir.'/database/migrations/2017_01_09_083946_create_articles_table.php',

Altough rollback or delete a migration file, the record related with the migration file remains in the composer autoload_classmap.php file.

To solve this problem, I have found composer command below from somewhere I can't remember.

composer dump-autoload

When I rand this code, the line related with the migration file that I deleted is gone. Then I ran:

php artisan make:migration create_articles_table --create=articles

Finally I recreated my migration file with same name

If PowerShell is available, the Send-MailMessage commandlet is a single one-line command that could easily be called from a batch file to handle email notifications. Below is a sample of the line you would include in your batch file to call the PowerShell script (the %xVariable% is a variable you might want to pass from your batch file to the PowerShell script):

--[BATCH FILE]--

:: ...your code here...
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe  -windowstyle hidden -command C:\MyScripts\EmailScript.ps1 %xVariable%

Below is an example of what you might include in your PowerShell script (you must include the PARAM line as the first non-remark line in your script if you included passing the %xVariable% from your batch file:

--[POWERSHELL SCRIPT]--

Param([String]$xVariable)
# ...your code here...
$smtp = "smtp.[emaildomain].com"
$to = "[Send to email address]"
$from = "[From email address]" 
$subject = "[Subject]" 
$body = "[Text you want to include----the <br> is a line feed: <br> <br>]"    
$body += "[This could be a second line of text]" + "<br> "

$attachment="[file name if you would like to include an attachment]"

I've been testing alternatives to C# Web browser component for few days now and here is my list:

1. Using newer IE versions 8,9:

Web Browser component is IE7 not IE8? How to change this?

Pros:

• Not much work required to get it running
• some HTML5/CSS3 support if IE9, full if IE10

Cons:

• Target machine must have target IE version installed, IE10 is still in preview on Win7

This doesn't require much work and you can get some HTML5 and CSS3 support although IE9 lacks some of best CSS3 and HTML5 features. But I'm sure you could get IE10 running same way. The problem would be that target system would have to have IE10 installed, and since is still in preview on Windows 7 I would suggest against it.

2. OpenWebKitSharp

OpenWebKitSharp is a .net wrapper for the webkit engine based on the WebKit.NET 0.5 project. WebKit is a layout engine used by Chrome/Safari

Pros:

• Actively developed
• HTML5/CSS3 support

Cons:

• Many features not implemented
• Doesn't support x64 (App must be built for x86)

OpenWebKit is quite nice although many features are not yet implemented, I experienced few issues using it with visual studio which throws null object reference here and then in design mode, there are some js problems. Everyone using it will almost immediately notice js alert does nothing. Events like mouseup,mousedown... etc. doesn't work, js drag and drop is buggy and so on..

I also had some difficulties installing it since it requires specific version of VC redistributable installed, so after exception I looked at event log, found version of VC and installed it.

3. GeckoFX

Pros:

• Works on mono
• Actively developed
• HTML5/CSS3 support

Cons:

• D?o?e?s?n?'?t? ?s?u?p?p?o?r?t? ?x?6?4? ?(?A?p?p? ?m?u?s?t? ?b?e? ?b?u?i?l?t? ?f?o?r? ?x?8?6?)? - see comments below

GeckoFX is a cross platform Webrowser control for embedding into WinForms Applications. This can be used with .NET on Windows and with mono on Linux. Gecko is a layout engine used by Firefox.

I bumped into few information that GeckoFX is not actively developed which is not true, of course it's always one or two versions behind of Firefox but that is normal, I was really impressed by activity and the control itself. It does everything I needed, but I needed some time to get it running, here's a little tutorial to get it running:

1. Download GeckoFx-Windows-16.0-0.2, here you can check if newer is available GeckoFX
2. Add references to two downloaded dll's
3. Since GeckoFX is wrapper you need XulRunner, go to Version List to see which one you need
4. Now that we know which version of XulRunner we need, we go to Mozilla XulRunner releases, go to version folder -> runtimes -> xulrunner-(your_version).en-US.win32.zip, in our case xulrunner-16.0.en-US.win32.zip
5. Unzip everything and copy all files to your bin\Debug (or release if your project is set to release)
6. Go to visual studio designer of your form, go to toolbox, right click inside -> Choose items -> Browse -> Find downloaded GeckoFX winforms dll file -> OK
7. Now you should have new control GeckoWebBrowser

If your really must use Chrome, take a look at this product called Awesomium, it's free for non-commercial projects, but license is few thousand dollars for commercial.

My problem was I'm using RVM and had the wrong Ruby version activated...

Hope this helps at least one person

Old versions of JavaScript (< ES5) require using a for..in loop:

for (var key in data) {
  if (data.hasOwnProperty(key)) {
    // do something with key
  }
}

ES5 introduces Object.keys and Array#forEach which makes this a little easier:

var data = { foo: 'bar', baz: 'quux' };

Object.keys(data); // ['foo', 'baz']
Object.keys(data).map(function(key){ return data[key] }) // ['bar', 'quux']
Object.keys(data).forEach(function (key) {
  // do something with data[key]
});

ES2017 introduces Object.values and Object.entries.

Object.values(data) // ['bar', 'quux']
Object.entries(data) // [['foo', 'bar'], ['baz', 'quux']]

Try https://checkstyle.sourceforge.io/config_filters.html#SuppressionXpathFilter

You can configure it as:

<module name="SuppressionXpathFilter">
  <property name="file" value="suppressions-xpath.xml"/>
  <property name="optional" value="false"/>
</module>
        

Generate Xpath suppressions using the CLI with the -g option and specify the output using the -o switch.

https://checkstyle.sourceforge.io/cmdline.html#Command_line_usage

Here's an ant snippet that will help you set up your Checkstyle suppressions auto generation; you can integrate it into Maven using the Antrun plugin.

<target name="checkstyleg">
    <move file="suppressions-xpath.xml"
      tofile="suppressions-xpath.xml.bak"
      preservelastmodified="true"
      force="true"
      failonerror="false"
      verbose="true"/>
    <fileset dir="${basedir}"
                    id="javasrcs">
    <include name="**/*.java" />
    </fileset>
    <pathconvert property="sources"
                            refid="javasrcs"
                            pathsep=" " />
    <loadfile property="cs.cp"
                        srcFile="../${cs.classpath.file}" />
    <java classname="${cs.main.class}"
                logError="true">
    <arg line="-c ../${cs.config} -p ${cs.properties} -o ${ant.project.name}-xpath.xml -g ${sources}" />
    <classpath>
        <pathelement path="${cs.cp}" />
        <pathelement path="${java.class.path}" />
    </classpath>
</java>
<condition property="file.is.empty" else="false">
     <length file="${ant.project.name}-xpath.xml" when="equal" length="0" />
   </condition>
   <if>
     <equals arg1="${file.is.empty}" arg2="false"/>
     <then>
     <move file="${ant.project.name}-xpath.xml"
      tofile="suppressions-xpath.xml"
      preservelastmodified="true"
      force="true"
      failonerror="true"
  verbose="true"/>
   </then>
</if>
    </target>

The suppressions-xpath.xml is specified as the Xpath suppressions source in the Checkstyle rules configuration. In the snippet above, I'm loading the Checkstyle classpath from a file cs.cp into a property. You can choose to specify the classpath directly.

Or you could use groovy within Maven (or Ant) to do the same:

import java.nio.file.Files
import java.nio.file.StandardCopyOption  
import java.nio.file.Paths

def backupSuppressions() {
  def supprFileName = 
      project.properties["checkstyle.suppressionsFile"]
  def suppr = Paths.get(supprFileName)
  def target = null
  if (Files.exists(suppr)) {
    def supprBak = Paths.get(supprFileName + ".bak")
    target = Files.move(suppr, supprBak,
        StandardCopyOption.REPLACE_EXISTING)
    println "Backed up " + supprFileName
  }
  return target
}

def renameSuppressions() {
  def supprFileName = 
      project.properties["checkstyle.suppressionsFile"]
  def suppr = Paths.get(project.name + "-xpath.xml")
  def target = null
  if (Files.exists(suppr)) {

The only drawback with using Xpath suppressions---besides the checks it doesn't support---is if you have code like the following:

package cstests;

public interface TestMagicNumber {
  static byte[] getAsciiRotator() {
    byte[] rotation = new byte[95 * 2];
    for (byte i = ' '; i <= '~'; i++) {
      rotation[i - ' '] = i;
      rotation[i + 95 - ' '] = i;
    }
    return rotation;
  }
}

The Xpath suppression generated in this case is not ingested by Checkstyle and the checker fails with an exception on the generated suppression:

<suppress-xpath
       files="TestMagicNumber.java"
       checks="MagicNumberCheck"
       query="/INTERFACE_DEF[./IDENT[@text='TestMagicNumber']]/OBJBLOCK/METHOD_DEF[./IDENT[@text='getAsciiRotator']]/SLIST/LITERAL_FOR/SLIST/EXPR/ASSIGN[./IDENT[@text='i']]/INDEX_OP[./IDENT[@text='rotation']]/EXPR/MINUS[./CHAR_LITERAL[@text='' '']]/PLUS[./IDENT[@text='i']]/NUM_INT[@text='95']"/>

Generating Xpath suppressions is recommended when you have fixed all other violations and wish to suppress the rest. It will not allow you to select specific instances in the code to suppress. You can , however, pick and choose suppressions from the generated file to do just that.

SuppressionXpathSingleFilter is better suited to identify and suppress a specific rule, file or error message. You can configure multiple filters identifying each one by the id attribute.

You can also do this

[Flags]
public enum MyEnum
{
    None   = 0,
    First  = 1 << 0,
    Second = 1 << 1,
    Third  = 1 << 2,
    Fourth = 1 << 3
}

I find the bit-shifting easier than typing 4,8,16,32 and so on. It has no impact on your code because it's all done at compile time

Like tomash said before: There's no easy way.

You might want to take a look at my answer here.
It explains how to realize a sliding (dimension changing) view.
In this case it was a left and right view: Left expanding, right disappearing.
It's might not do exactly what you need but with inventive spirit you can make it work ;)

Try this:

?q=-id:["" TO *]
