It don't create normally; you need to add it by yourself.

After adding Global.asax by

• Right clicking your website -> Add New Item -> Global Application Class -> Add

You need to add a class

• Right clicking App_Code -> Add New Item -> Class -> name it Global.cs -> Add

Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.

Your Global.asax will look like this: -

<%@ Application Language="C#" Inherits="Global" %>

Your Global.cs in App_Code will look like this: -

public class Global : System.Web.HttpApplication
{
    public Global()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
    /// Many other events like begin request...e.t.c, e.t.c
}

The Reason

You are not opening the page through a server, like Apache, so when the browser tries to obtain the resource it thinks it is from a separate domain, which is not allowed. Though some browsers do allow it.

The Solution

Run inetmgr and host your page locally and browse as http://localhost:portnumber/PageName.html or through a web server like Apache, nginx, node etc.

Alternatively use a different browser No error was shown when directly opening the page using Firefox and Safari. It comes only for Chrome and IE(xx).

If you are using code editors like Brackets, Sublime or Notepad++, those apps handle this error automatically.

Here very simple method

let data = string.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

Adding onto @demented hedgehog answer on using find()

In terms of efficiency

It may be worth first checking to see if s1 is in s2 before calling find().
This can be more efficient if you know that most of the times s1 won't be a substring of s2

Since the in operator is very efficient

 s1 in s2

It can be more efficient to convert:

index = s2.find(s1)

to

index = -1
if s1 in s2:
   index = s2.find(s1)

This is useful for when find() is going to be returning -1 a lot.

I found it substantially faster since find() was being called many times in my algorithm, so I thought it was worth mentioning

Pure Python2 w/o dep:

def relpath(cwd, path):
    """Create a relative path for path from cwd, if possible"""
    if sys.platform == "win32":
        cwd = cwd.lower()
        path = path.lower()
    _cwd = os.path.abspath(cwd).split(os.path.sep)
    _path = os.path.abspath(path).split(os.path.sep)
    eq_until_pos = None
    for i in xrange(min(len(_cwd), len(_path))):
        if _cwd[i] == _path[i]:
            eq_until_pos = i
        else:
            break
    if eq_until_pos is None:
        return path
    newpath = [".." for i in xrange(len(_cwd[eq_until_pos+1:]))]
    newpath.extend(_path[eq_until_pos+1:])
    return os.path.join(*newpath) if newpath else "."

It is actually very simple. You don't have to go through a lot of stuff. Just run the following command in terminal and follow on-screen instructions.

sudo mysql_secure_installation

I like the answer of Anacrust, though, by the fact "console.log" is executed twice, I would like to do a small update for src/mylib.js:

let test = {
  foo () { return 'foo' },
  bar () { return 'bar' },
  baz () { return 'baz' }
}

export default test

All other code remains the same...

Implement the iteration as a recursive function.

Function Iterate( i , N )
  If i == N Then
      Exit Function
  End If
  [Code]
  If Condition1 Then
     Call Iterate( i+1, N );
     Exit Function
  End If

  [Code]
  If Condition2 Then
     Call Iterate( i+1, N );
     Exit Function
  End If
  Call Iterate( i+1, N );
End Function

Start with a call to Iterate( 1, N )

To get the latest tag only on the current branch/tag name that prefixes with current branch, I had to execute the following

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags --abbrev=0 $BRANCH^ | grep $BRANCH

Branch master:

git checkout master

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags 
--abbrev=0 $BRANCH^ | grep $BRANCH

master-1448

Branch custom:

git checkout 9.4

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags 
--abbrev=0 $BRANCH^ | grep $BRANCH

9.4-6

And my final need to increment and get the tag +1 for next tagging.

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags  --abbrev=0 $BRANCH^ | grep $BRANCH | awk -F- '{print $NF}'

While pop and delete both take indices to remove an element as stated in above comments. A key difference is the time complexity for them. The time complexity for pop() with no index is O(1) but is not the same case for deletion of last element.

If your use case is always to delete the last element, it's always preferable to use pop() over delete(). For more explanation on time complexities, you can refer to https://www.ics.uci.edu/~pattis/ICS-33/lectures/complexitypython.txt

Let suppose we have a primary color in values=>colors.xml as:

<resources>
    <color name="primary">#FDD835</color>
</resources>

so if we want to use our custom color into setBackgroundColor(@ColorInt int Color) then we just need an annotation @SuppressLint("ResourceAsColor") with constructor/method which will be used as:

    @SuppressLint("ResourceAsColor")
    public _LinearLayout(Context context) {
        super(context);

        // Formatting our layout : )
        super.setBackgroundColor(R.color.primary);

        ....


    }

Unexpected T_STRING

T_STRING is a bit of a misnomer. It does not refer to a quoted "string". It means a raw identifier was encountered. This can range from bare words to leftover CONSTANT or function names, forgotten unquoted strings, or any plain text.

1. Misquoted strings

   This syntax error is most common for misquoted string values however. Any unescaped and stray " or ' quote will form an invalid expression:

                  ?                  ?
    echo "<a href="http://example.com">click here</a>";
   

   Syntax highlighting will make such mistakes super obvious. It's important to remember to use backslashes for escaping \" double quotes, or \' single quotes - depending on which was used as string enclosure.

   • For convenience you should prefer outer single quotes when outputting plain HTML with double quotes within.
   • Use double quoted strings if you want to interpolate variables, but then watch out for escaping literal " double quotes.
   • For lengthier output, prefer multiple echo/print lines instead of escaping in and out. Better yet consider a HEREDOC section.

   
   Another example is using PHP entry inside HTML code generated with PHP:

   $text = '<div>some text with <?php echo 'some php entry' ?></div>'
   

   This happens if $text is large with many lines and developer does not see the whole PHP variable value and focus on the piece of code forgetting about its source. Example is here

   See also What is the difference between single-quoted and double-quoted strings in PHP?.

2. Unclosed strings

   If you miss a closing " then a syntax error typically materializes later. An unterminated string will often consume a bit of code until the next intended string value:

                                                          ?
   echo "Some text", $a_variable, "and some runaway string ;
   success("finished");
            ?
   

   It's not just literal T_STRINGs which the parser may protest then. Another frequent variation is an Unexpected '>' for unquoted literal HTML.

3. Non-programming string quotes

   If you copy and paste code from a blog or website, you sometimes end up with invalid code. Typographic quotes aren't what PHP expects:

   $text = ’Something something..’ + ”these ain't quotes”;
   

   Typographic/smart quotes are Unicode symbols. PHP treats them as part of adjoining alphanumeric text. For example ”these is interpreted as a constant identifier. But any following text literal is then seen as a bareword/T_STRING by the parser.

4. The missing semicolon; again

   If you have an unterminated expression in previous lines, then any following statement or language construct gets seen as raw identifier:

          ?
   func1()
   function2();
   

   PHP just can't know if you meant to run two functions after another, or if you meant to multiply their results, add them, compare them, or only run one || or the other.

5. Short open tags and <?xml headers in PHP scripts

   This is rather uncommon. But if short_open_tags are enabled, then you can't begin your PHP scripts with an XML declaration:

         ?
   <?xml version="1.0"?>
   

   PHP will see the <? and reclaim it for itself. It won't understand what the stray xml was meant for. It'll get interpreted as constant. But the version will be seen as another literal/constant. And since the parser can't make sense of two subsequent literals/values without an expression operator in between, that'll be a parser failure.

6. Invisible Unicode characters

   A most hideous cause for syntax errors are Unicode symbols, such as the non-breaking space. PHP allows Unicode characters as identifier names. If you get a T_STRING parser complaint for wholly unsuspicious code like:

   <?php
       print 123;
   

   You need to break out another text editor. Or an hexeditor even. What looks like plain spaces and newlines here, may contain invisible constants. Java-based IDEs are sometimes oblivious to an UTF-8 BOM mangled within, zero-width spaces, paragraph separators, etc. Try to reedit everything, remove whitespace and add normal spaces back in.

   You can narrow it down with with adding redundant ; statement separators at each line start:

   <?php
       ;print 123;
   

   The extra ; semicolon here will convert the preceding invisible character into an undefined constant reference (expression as statement). Which in return makes PHP produce a helpful notice.

7. The `$` sign missing in front of variable names

   Variables in PHP are represented by a dollar sign followed by the name of the variable.

   The dollar sign ($) is a sigil that marks the identifier as a name of a variable. Without this sigil, the identifier could be a language keyword or a constant.

   This is a common error when the PHP code was "translated" from code written in another language (C, Java, JavaScript, etc.). In such cases, a declaration of the variable type (when the original code was written in a language that uses typed variables) could also sneak out and produce this error.

8. Escaped Quotation marks

   If you use \ in a string, it has a special meaning. This is called an "Escape Character" and normally tells the parser to take the next character literally.

   Example: echo 'Jim said \'Hello\''; will print Jim said 'hello'

   If you escape the closing quote of a string, the closing quote will be taken literally and not as intended, i.e. as a printable quote as part of the string and not close the string. This will show as a parse error commonly after you open the next string or at the end of the script.

   Very common error when specifiying paths in Windows: "C:\xampp\htdocs\" is wrong. You need "C:\\xampp\\htdocs\\".

9. Typed properties

   You need PHP =7.4 to use property typing such as:

   public stdClass $obj;
   

You need to surround $file = readdir($handle) with parentheses.

Here you go:

$log_directory = 'your_dir_name_here';

$results_array = array();

if (is_dir($log_directory))
{
        if ($handle = opendir($log_directory))
        {
                //Notice the parentheses I added:
                while(($file = readdir($handle)) !== FALSE)
                {
                        $results_array[] = $file;
                }
                closedir($handle);
        }
}

//Output findings
foreach($results_array as $value)
{
    echo $value . '<br />';
}

Why to annoy the user with three different Dialog Boxes to enter things, why not do all this in one go in a single Dialog and save time, instead of testing the patience of the USER ?

You can add everything in a single Dialog, by putting all the fields on your JPanel and then adding this JPanel to your JOptionPane. Below code can clarify a bit more :

import java.awt.*;
import java.util.*;
import javax.swing.*;

public class AverageExample
{
    private double[] marks;
    private JTextField[] marksField;
    private JLabel resultLabel;

    public AverageExample()
    {
        marks = new double[3];
        marksField = new JTextField[3];
        marksField[0] = new JTextField(10);
        marksField[1] = new JTextField(10);
        marksField[2] = new JTextField(10);
    }

    private void displayGUI()
    {
        int selection = JOptionPane.showConfirmDialog(
                null, getPanel(), "Input Form : "
                                , JOptionPane.OK_CANCEL_OPTION
                                , JOptionPane.PLAIN_MESSAGE);

        if (selection == JOptionPane.OK_OPTION) 
        {
            for ( int i = 0; i < 3; i++)
            {
                marks[i] = Double.valueOf(marksField[i].getText());             
            }
            Arrays.sort(marks);
            double average = (marks[1] + marks[2]) / 2.0;
            JOptionPane.showMessageDialog(null
                    , "Average is : " + Double.toString(average)
                    , "Average : "
                    , JOptionPane.PLAIN_MESSAGE);
        }
        else if (selection == JOptionPane.CANCEL_OPTION)
        {
            // Do something here.
        }
    }

    private JPanel getPanel()
    {
        JPanel basePanel = new JPanel();
        //basePanel.setLayout(new BorderLayout(5, 5));
        basePanel.setOpaque(true);
        basePanel.setBackground(Color.BLUE.darker());

        JPanel centerPanel = new JPanel();
        centerPanel.setLayout(new GridLayout(3, 2, 5, 5));
        centerPanel.setBorder(
            BorderFactory.createEmptyBorder(5, 5, 5, 5));
        centerPanel.setOpaque(true);
        centerPanel.setBackground(Color.WHITE);

        JLabel mLabel1 = new JLabel("Enter Marks 1 : ");
        JLabel mLabel2 = new JLabel("Enter Marks 2 : ");
        JLabel mLabel3 = new JLabel("Enter Marks 3 : ");

        centerPanel.add(mLabel1);
        centerPanel.add(marksField[0]);
        centerPanel.add(mLabel2);
        centerPanel.add(marksField[1]);
        centerPanel.add(mLabel3);
        centerPanel.add(marksField[2]);

        basePanel.add(centerPanel);

        return basePanel;
    }

I just had this problem setting up my new laptop. The issue for me was that my toolchain (CodeSourcery) is 32bit and I had not installed the 32bit libs.

sudo apt-get install ia32-libs

2017 Update: Stackdriver Logging is now available for Google Apps Script. From the menu bar in the script editor, goto: View > Stackdriver Logging to view or stream the logs.

console.log() will write DEBUG level messages

Example onEdit() logging:

function onEdit (e) {
  var debug_e = {
    authMode:  e.authMode,  
    range:  e.range.getA1Notation(),    
    source:  e.source.getId(),
    user:  e.user,   
    value:  e.value,
    oldValue: e. oldValue
  }

  console.log({message: 'onEdit() Event Object', eventObject: debug_e});
}

Then check the logs in the Stackdriver UI labeled onEdit() Event Object to see the output

Following was working for me. hope this helps you

<add name="getconn" connectionString="Data Source=servername;Initial Catalog=DBName;Persist Security Info=True;User ID=sa;Password=***" />

You can use functional operation for a more neat code

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

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

The JSON string will just be the body of the response you get back from the URL you have called. So add this code

...
BufferedReader in = new BufferedReader(new InputStreamReader(
                            conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) 
    System.out.println(inputLine);
in.close();

That will allow you to see the JSON being returned to the console. The only missing piece you then have is using a JSON library to read that data and provide you with a Java representation.

Here's an example using JSON-LIB

The below code helps, if you use Gradle. Allows you to easily remove unneeded Google services (presuming you're using them) to get back below the 65k threshold. All credit to this post: https://gist.github.com/dmarcato/d7c91b94214acd936e42

Edit 2014-10-22: There's been a lot of interesting discussion on the gist referenced above. TLDR? look at this one: https://gist.github.com/Takhion/10a37046b9e6d259bb31

Paste this code at the bottom of your build.gradle file and adjust the list of google services you do not need:

def toCamelCase(String string) {
    String result = ""
    string.findAll("[^\\W]+") { String word ->
        result += word.capitalize()
    }
    return result
}

afterEvaluate { project ->
    Configuration runtimeConfiguration = project.configurations.getByName('compile')
    ResolutionResult resolution = runtimeConfiguration.incoming.resolutionResult
    // Forces resolve of configuration
    ModuleVersionIdentifier module = resolution.getAllComponents().find { it.moduleVersion.name.equals("play-services") }.moduleVersion

    String prepareTaskName = "prepare${toCamelCase("${module.group} ${module.name} ${module.version}")}Library"
    File playServiceRootFolder = project.tasks.find { it.name.equals(prepareTaskName) }.explodedDir

    Task stripPlayServices = project.tasks.create(name: 'stripPlayServices', group: "Strip") {
        inputs.files new File(playServiceRootFolder, "classes.jar")
        outputs.dir playServiceRootFolder
        description 'Strip useless packages from Google Play Services library to avoid reaching dex limit'

        doLast {
            copy {
                from(file(new File(playServiceRootFolder, "classes.jar")))
                into(file(playServiceRootFolder))
                rename { fileName ->
                    fileName = "classes_orig.jar"
                }
            }
            tasks.create(name: "stripPlayServices" + module.version, type: Jar) {
                destinationDir = playServiceRootFolder
                archiveName = "classes.jar"
                from(zipTree(new File(playServiceRootFolder, "classes_orig.jar"))) {
                    exclude "com/google/ads/**"

            }.execute()
            delete file(new File(playServiceRootFolder, "classes_orig.jar"))
        }

    project.tasks.findAll { it.name.startsWith('prepare') && it.name.endsWith('Dependencies') }.each { Task task ->
        task.dependsOn stripPlayServices

Strongly simplified version of max:

def max(items, key=lambda x: x):
    current = item[0]
    for item in items:
        if key(item) > key(current):
            current = item
    return current

Regarding lambda:

>>> ident = lambda x: x
>>> ident(3)
3
>>> ident(5)
5

>>> times_two = lambda x: 2*x
>>> times_two(2)
4

In general, if you are starting at 0 and going upward, always use an unsigned type to avoid an overflow taking you into a negative value situation. This is critically important, because if your array bounds happens to be less than the max of your loop, but your loop max happens to be greater than the max of your type, you will wrap around negative and you may experience a segmentation fault (SIGSEGV). So, in general, never use int for a loop starting at 0 and going upwards. Use an unsigned.

Check your topic list on firebase console.

1. Go to firebase console

2. Click Grow from side menu

3. Click Cloud Messaging

4. Click Send your first message

5. In the notification section, type something for Notification title and Notification text

6. Click Next

7. In target section click Topic

8. Click on Message topic textbox, then you can see your topics (I didn't created topic called android or ios, but I can see those two topics.

9. When you send push notification add this as your condition.

   "condition"=> "'all' in topics || 'android' in topics || 'ios' in topics",

Full body

array(
    "notification"=>array(
        "title"=>"Test",
        "body"=>"Test Body",
    ),
    "condition"=> "'all' in topics || 'android' in topics || 'ios' in topics",
);

If you have more topics you can add those with || (or) condition, Then all users will get your notification. Tested and worked for me.

Using <summary> and <details>

Using <summary> and <details> elements is the simplest but see browser support as current IE is not supporting it. You can polyfill though (most are jQuery-based). Do note that unsupported browser will simply show the expanded version of course, so that may be acceptable in some cases.

/* Optional styling */_x000D_
summary::-webkit-details-marker {_x000D_
  color: blue;_x000D_
}_x000D_
summary:focus {_x000D_
  outline-style: none;_x000D_
}

<details>_x000D_
  <summary>Summary, caption, or legend for the content</summary>_x000D_
  Content goes here._x000D_
</details>

See also how to style the <details> element (HTML5 Doctor) (little bit tricky).

Pure CSS3

The :target selector has a pretty good browser support, and it can be used to make a single collapsible element within the frame.

.details,_x000D_
.show,_x000D_
.hide:target {_x000D_
  display: none;_x000D_
}_x000D_
.hide:target + .show,_x000D_
.hide:target ~ .details {_x000D_
  display: block;_x000D_
}

<div>_x000D_
  <a id="hide1" href="#hide1" class="hide">+ Summary goes here</a>_x000D_
  <a id="show1" href="#show1" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>_x000D_
<div>_x000D_
  <a id="hide2" href="#hide2" class="hide">+ Summary goes here</a>_x000D_

Here is sample of raw pointer iterator.

You shouldn't use iterator class to work with raw pointers!

#include <iostream>
#include <vector>
#include <list>
#include <iterator>
#include <assert.h>

template<typename T>
class ptr_iterator
    : public std::iterator<std::forward_iterator_tag, T>
{
    typedef ptr_iterator<T>  iterator;
    pointer pos_;
public:
    ptr_iterator() : pos_(nullptr) {}
    ptr_iterator(T* v) : pos_(v) {}
    ~ptr_iterator() {}

    iterator  operator++(int) /* postfix */         { return pos_++; }
    iterator& operator++()    /* prefix */          { ++pos_; return *this; }
    reference operator* () const                    { return *pos_; }
    pointer   operator->() const                    { return pos_; }
    iterator  operator+ (difference_type v)   const { return pos_ + v; }
    bool      operator==(const iterator& rhs) const { return pos_ == rhs.pos_; }
    bool      operator!=(const iterator& rhs) const { return pos_ != rhs.pos_; }
};

template<typename T>
ptr_iterator<T> begin(T *val) { return ptr_iterator<T>(val); }


template<typename T, typename Tsize>
ptr_iterator<T> end(T *val, Tsize size) { return ptr_iterator<T>(val) + size; }

Raw pointer range based loop workaround. Please, correct me, if there is better way to make range based loop from raw pointer.

template<typename T>
class ptr_range
{
    T* begin_;
    T* end_;
public:
    ptr_range(T* ptr, size_t length) : begin_(ptr), end_(ptr + length) { assert(begin_ <= end_); }
    T* begin() const { return begin_; }
    T* end() const { return end_; }
};

template<typename T>
ptr_range<T> range(T* ptr, size_t length) { return ptr_range<T>(ptr, length); }

And simple test

void DoIteratorTest()
{
    const static size_t size = 10;
    uint8_t *data = new uint8_t[size];
    {
        // Only for iterator test
        uint8_t n = '0';
        auto first = begin(data);
        auto last = end(data, size);
        for (auto it = first; it != last; ++it)
        {
            *it = n++;
        }

        // It's prefer to use the following way:
        for (const auto& n : range(data, size))
        {
            std::cout << " char: " << static_cast<char>(n) << std::endl;
        }
    }
    {
        // Only for iterator test
        ptr_iterator<uint8_t> first(data);
        ptr_iterator<uint8_t> last(first + size);
        std::vector<uint8_t> v1(first, last);

        // It's prefer to use the following way:
        std::vector<uint8_t> v2(data, data + size);
    }
    {
        std::list<std::vector<uint8_t>> queue_;
        queue_.emplace_back(begin(data), end(data, size));
        queue_.emplace_back(data, data + size);
    }
}

Here's a solution using a negative lookahead (not supported in all regex engines):

^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$

Test that it works as expected:

import re
tests = [
   ('a', True),
   ('_', False),
   ('zz', True),
   ('a0', True),
   ('A_', False),
   ('a0_b', True),
   ('a__b', False),
   ('a_1_c', True),
]

regex = '^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$'
for test in tests:
   is_match = re.match(regex, test[0]) is not None
   if is_match != test[1]:
       print "fail: "  + test[0]

Use <br /> for new line in html:

display_txt = display_txt.replace(/\n/g, "<br />");

To communicate between an Activity and Fragments, there are several options, but after lots of reading and many experiences, I found out that it could be resumed this way:

• Activity wants to communicate with child Fragment => Simply write public methods in your Fragment class, and let the Activity call them
• Fragment wants to communicate with the parent Activity => This requires a bit more of work, as the official Android link https://developer.android.com/training/basics/fragments/communicating suggests, it would be a great idea to define an interface that will be implemented by the Activity, and which will establish a contract for any Activity that wants to communicate with that Fragment. For example, if you have FragmentA, which wants to communicate with any activity that includes it, then define the FragmentAInterface which will define what method can the FragmentA call for the activities that decide to use it.
• A Fragment wants to communicate with other Fragment => This is the case where you get the most 'complicated' situation. Since you could potentially need to pass data from FragmentA to FragmentB and viceversa, that could lead us to defining 2 interfaces, FragmentAInterface which will be implemented by FragmentB and FragmentAInterface which will be implemented by FragmentA. That will start making things messy. And imagine if you have a few more Fragments on place, and even the parent activity wants to communicate with them. Well, this case is a perfect moment to establish a shared ViewModel for the activity and it's fragments. More info here https://developer.android.com/topic/libraries/architecture/viewmodel . Basically, you need to define a SharedViewModel class, that has all the data you want to share between the activity and the fragments that will be in need of communicating data among them.

The ViewModel case, makes things pretty simpler at the end, since you don't have to add extra logic that makes things dirty in the code and messy. Plus it will allow you to separate the gathering (through calls to an SQLite Database or an API) of data from the Controller (activities and fragments).

Add this to your css.

.highcharts-credits {
display: none !important;
}

If you want to add a product into the array you can use:

$item['product'] = $product;

You might find your code is more maintainable if you keep all your styles, etc. in CSS and just set / unset class names in JavaScript.

Your CSS would obviously be something like:

.highlight {
    background:#ff00aa;
}

Then in JavaScript:

element.className = element.className === 'highlight' ? '' : 'highlight';

If you don't want to use Windows Forms nor edit manifest files, I came up with a very simple hack using WPF's SaveAs dialog for actually selecting a directory.

No using directive needed, you may simply copy-paste the code below !

It should still be very user-friendly and most people will never notice.

The idea comes from the fact that we can change the title of that dialog, hide files, and work around the resulting filename quite easily.

It is a big hack for sure, but maybe it will do the job just fine for your usage...

In this example I have a textbox object to contain the resulting path, but you may remove the related lines and use a return value if you wish...

// Create a "Save As" dialog for selecting a directory (HACK)
var dialog = new Microsoft.Win32.SaveFileDialog();
dialog.InitialDirectory = textbox.Text; // Use current value for initial dir
dialog.Title = "Select a Directory"; // instead of default "Save As"
dialog.Filter = "Directory|*.this.directory"; // Prevents displaying files
dialog.FileName = "select"; // Filename will then be "select.this.directory"
if (dialog.ShowDialog() == true) {
    string path = dialog.FileName;
    // Remove fake filename from resulting path
    path = path.Replace("\\select.this.directory", "");
    path = path.Replace(".this.directory", "");
    // If user has changed the filename, create the new directory
    if (!System.IO.Directory.Exists(path)) {
        System.IO.Directory.CreateDirectory(path);
    }
    // Our final value is in path
    textbox.Text = path;
}

The only issues with this hack are :

• Acknowledge button still says "Save" instead of something like "Select directory", but in a case like mines I "Save" the directory selection so it still works...
• Input field still says "File name" instead of "Directory name", but we can say that a directory is a type of file...
• There is still a "Save as type" dropdown, but its value says "Directory (*.this.directory)", and the user cannot change it for something else, works for me...

Most people won't notice these, although I would definitely prefer using an official WPF way if microsoft would get their heads out of their asses, but until they do, that's my temporary fix.

Just use DOMDocument->loadHTML() and be done with it. libxml's HTML parsing algorithm is quite good and fast, and contrary to popular belief, does not choke on malformed HTML.

If you are trying to determine the width of a mix of text nodes and elements inside a given element, you need to wrap all the contents with wrapInner(), calculate the width, and then unwrap the contents.

*Note: You will also need to extend jQuery to add an unwrapInner() function since it is not provided by default.

$.fn.extend({
  unwrapInner: function(selector) {
      return this.each(function() {
          var t = this,
              c = $(t).children(selector);
          if (c.length === 1) {
              c.contents().appendTo(t);
              c.remove();
          }
      });
  },
  textWidth: function() {
    var self = $(this);
    $(this).wrapInner('<span id="text-width-calc"></span>');
    var width = $(this).find('#text-width-calc').width();
    $(this).unwrapInner();
    return width;
  }
});

Another solution.

const frame = document.getElementById("my-iframe");

frame.parentNode.replaceChild(frame.cloneNode(), frame);

This issue is caused by the pipeline mode in your Application Pool setting that your web site is set to.

Short

• Simple way Change the Application Pool mode to one that has Classic pipeline enabled.
• Correct way Your web.config / web app will need to be altered to support Integrated pipelines. Normally this is as simple as removing parts of your web.config.

• Simple way (bad practice) Add the following to your web.config. See http://www.iis.net/ConfigReference/system.webServer/validation

   <system.webServer>
       <validation validateIntegratedModeConfiguration="false" />
   </system.webServer>
  

Long If possible, your best bet is to change your application to support the integrated pipelines. There are a number of changes between IIS6 and IIS7.x that will cause this error. You can find details about these changes here http://learn.iis.net/page.aspx/381/aspnet-20-breaking-changes-on-iis-70/.

If you're unable to do that, you'll need to change the App pool which may be more difficult to do depending on your availability to the web server.

• Go to the web server
• Open the IIS Manager
• Navigate to your site
• Click Advanced Settings on the right Action pane
• Under Application Pool, change it to an app pool that has classic enabled.

Check http://technet.microsoft.com/en-us/library/cc731755(WS.10).aspx for details on changing the App Pool

If you need to create an App Pool with Classic pipelines, take a look at http://technet.microsoft.com/en-us/library/cc731784(WS.10).aspx

If you don't have access to the server to make this change, you'll need to do this through your hosting server and contact them for help.

Feel free to ask questions.

This works for me:

URL url = new URL("http://upload.wikimedia.org/wikipedia/commons/9/9c/Image-Porkeri_001.jpg");
InputStream in = new BufferedInputStream(url.openStream());
OutputStream out = new BufferedOutputStream(new FileOutputStream("Image-Porkeri_001.jpg"));

for ( int i; (i = in.read()) != -1; ) {
    out.write(i);
}
in.close();
out.close();

You can use the open event handler to apply additional styling:

 open: function(event) {
     $('.ui-dialog-buttonpane').find('button:contains("Cancel")').addClass('cancelButton');
 }

Combined with the answer from Andrew Sohn (https://stackoverflow.com/a/14265207/1929406)

branchcreated=$(git reflog show --date=format:'%Y-%m-%d %H:%M:%S' --all | sed 's!^.*refs/!refs/!' | grep '/master' | tail -1| cut -d'{' -f 2| cut -d'}' -f 1 | xargs)
echo $branchcreated

The immediate problem is you have is with quoting: by using double quotes ("..."), your variable references are instantly expanded, which is probably not what you want.

Use single quotes instead - strings inside single quotes are not expanded or interpreted in any way by the shell.

(If you want selective expansion inside a string - i.e., expand some variable references, but not others - do use double quotes, but prefix the $ of references you do not want expanded with \; e.g., \$var).

However, you're better off using a single here-doc[ument], which allows you to create multi-line stdin input on the spot, bracketed by two instances of a self-chosen delimiter, the opening one prefixed by <<, and the closing one on a line by itself - starting at the very first column; search for Here Documents in man bash or at http://www.gnu.org/software/bash/manual/html_node/Redirections.html.

If you quote the here-doc delimiter (EOF in the code below), variable references are also not expanded. As @chepner points out, you're free to choose the method of quoting in this case: enclose the delimiter in single quotes or double quotes, or even simply arbitrarily escape one character in the delimiter with \:

echo "creating new script file."

cat <<'EOF'  > "$servfile"
#!/bin/bash
read -p "Please enter a service: " ser
servicetest=`getsebool -a | grep ${ser}` 
if [ $servicetest > /dev/null ]; then 
  echo "we are now going to work with ${ser}"
else
  exit 1
fi
EOF

As @BruceK notes, you can prefix your here-doc delimiter with - (applied to this example: <<-"EOF") in order to have leading tabs stripped, allowing for indentation that makes the actual content of the here-doc easier to discern. Note, however, that this only works with actual tab characters, not leading spaces.

Employing this technique combined with the afterthoughts regarding the script's content below, we get (again, note that actual tab chars. must be used to lead each here-doc content line for them to get stripped):

cat <<-'EOF' > "$servfile"
    #!/bin/bash
    read -p "Please enter a service name: " ser
    if [[ -n $(getsebool -a | grep "${ser}") ]]; then 
      echo "We are now going to work with ${ser}."
    else
      exit 1
    fi
EOF

Finally, note that in bash even normal single- or double-quoted strings can span multiple lines, but you won't get the benefits of tab-stripping or line-block scoping, as everything inside the quotes becomes part of the string.

Thus, note how in the following #!/bin/bash has to follow the opening ' immediately in order to become the first line of output:

echo '#!/bin/bash
read -p "Please enter a service: " ser
servicetest=$(getsebool -a | grep "${ser}")
if [[ -n $servicetest ]]; then 
  echo "we are now going to work with ${ser}"
else
  exit 1
fi' > "$servfile"

Afterthoughts regarding the contents of your script:

• The syntax $(...) is preferred over `...` for command substitution nowadays.
• You should double-quote ${ser} in the grep command, as the command will likely break if the value contains embedded spaces (alternatively, make sure that the valued read contains no spaces or other shell metacharacters).
• Use [[ -n $servicetest ]] to test whether $servicetest is empty (or perform the command substitution directly inside the conditional) - [[ ... ]] - the preferred form in bash - protects you from breaking the conditional if the $servicetest happens to have embedded spaces; there's NEVER a need to suppress stdout output inside a conditional (whether [ ... ] or [[ ... ]], as no stdout output is passed through; thus, the > /dev/null is redundant (that said, with a command substitution inside a conditional, stderr output IS passed through).

I had similar problems as people here with Nexus 5 on Windows 7. No .inf file edits were needed, my computer was stuck on an old version of the Google USB drivers (7.0.0.1). Windows 7 refused to install the newer version even if I tried to manually select the directory or .inf file. Had to manually delete specific cached .inf files in WINDOWS\inf folder, follow directions here: http://code.google.com/p/android/issues/detail?id=62365#c7

Also be sure USB debugging is turned on in developer options. There's a trick to expose the developer options, click 7 times on the build number at the bottom of the "About Phone" information!

I didn't know the existing sa password so this is what I did:

1. Open Services in Control Panel

2. Find the "SQL Server (SQLEXPRESS)" entry and select properties

3. Stop the service

4. Enter "-m" at the beginning of the "Start parameters" fields. If there are other parameters there already add a semi-colon after -m;

5. Start the service

6. Open a Command Prompt

Enter the command:

osql -S YourPcName\SQLEXPRESS -E

(change YourPcName to whatever your PC is called).

7. At the prompt type the following commands:

alter login sa enable
go
sp_password NULL,'new_password','sa'
go
quit

8. Stop the "SQL Server (SQLEXPRESS)" service

9. Remove the "-m" from the Start parameters field

10. Start the service

To replace only factors:

i <- sapply(bob, is.factor)
bob[i] <- lapply(bob[i], as.character)

In package dplyr in version 0.5.0 new function mutate_if was introduced:

library(dplyr)
bob %>% mutate_if(is.factor, as.character) -> bob

...and in version 1.0.0 was replaced by across:

library(dplyr)
bob %>% mutate(across(where(is.factor), as.character)) -> bob

Package purrr from RStudio gives another alternative:

library(purrr)
bob %>% modify_if(is.factor, as.character) -> bob

Passing an array of items as a collapsed parameter to the WHERE..IN clause will fail since query will take form of WHERE Age IN ("11, 13, 14, 16").

But you can pass your parameter as an array serialized to XML or JSON:

Using nodes() method:

StringBuilder sb = new StringBuilder();

foreach (ListItem item in ddlAge.Items)
  if (item.Selected)
    sb.Append("<age>" + item.Text + "</age>"); // actually it's xml-ish

sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
    SELECT Tab.col.value('.', 'int') as Age from @Ages.nodes('/age') as Tab(col))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = sb.ToString();

Using OPENXML method:

using System.Xml.Linq;
...
XElement xml = new XElement("Ages");

foreach (ListItem item in ddlAge.Items)
  if (item.Selected)
    xml.Add(new XElement("age", item.Text);

sqlComm.CommandText = @"DECLARE @idoc int;
    EXEC sp_xml_preparedocument @idoc OUTPUT, @Ages;
    SELECT * from TableA WHERE Age IN (
    SELECT Age from OPENXML(@idoc, '/Ages/age') with (Age int 'text()')
    EXEC sp_xml_removedocument @idoc";
sqlComm.Parameters.Add("@Ages", SqlDbType.Xml);
sqlComm.Parameters["@Ages"].Value = xml.ToString();

That's a bit more on the SQL side and you need a proper XML (with root).

Using OPENJSON method (SQL Server 2016+):

using Newtonsoft.Json;
...
List<string> ages = new List<string>();

foreach (ListItem item in ddlAge.Items)
  if (item.Selected)
    ages.Add(item.Text);

sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
    select value from OPENJSON(@Ages))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = JsonConvert.SerializeObject(ages);

Note that for the last method you also need to have Compatibility Level at 130+.

That's a lot of questions.

1. Why EOF is -1: usually -1 in POSIX system calls is returned on error, so i guess the idea is "EOF is kind of error"

2. any boolean operation (including !=) returns 1 in case it's TRUE, and 0 in case it's FALSE, so getchar() != EOF is 0 when it's FALSE, meaning getchar() returned EOF.

3. in order to emulate EOF when reading from stdin press Ctrl+D

Ok uninstall the app, but we admit that the data not must be lost? This can be resolve, upgrading versionCode and versionName and try the application in "Release" mode.

For example, this is important when we want to try the migration of our Database. We can compare the our application on play store with actual application not release yet.

You have two ways to do it.

First

Import the image on top of the class and then reference it in your <img/> element like this

import React, { Component } from 'react';
import myImg from '../path/myImg.svg';

export default class HelloImage extends Component {
  render() {
    return <img src={myImg} width="100" height="50" /> 
  }
} 

Second

You can directly specify the image path using require('../pathToImh/img') in <img/> element like this

import React, { Component } from 'react'; 

export default class HelloImage extends Component {
  render() {
    return <img src={require(../path/myImg.svg)} width="100" height="50" /> 
  }
}

Java doesn't parse ISO dates correctly.

Similar to McKenzie's answer.

Just fix the Z before parsing.

Code

String string = "2013-03-05T18:05:05.000Z";
String defaultTimezone = TimeZone.getDefault().getID();
Date date = (new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ")).parse(string.replaceAll("Z$", "+0000"));

System.out.println("string: " + string);
System.out.println("defaultTimezone: " + defaultTimezone);
System.out.println("date: " + (new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ")).format(date));

Result

string: 2013-03-05T18:05:05.000Z
defaultTimezone: America/New_York
date: 2013-03-05T13:05:05.000-0500

for select2 v4.0.0 slightly different

$(".itemSearch").select2({
    tags: true,
    multiple: true,
    tokenSeparators: [',', ' '],
    minimumInputLength: 2,
    minimumResultsForSearch: 10,
    ajax: {
        url: URL,
        dataType: "json",
        type: "GET",
        data: function (params) {

            var queryParameters = {
                term: params.term
            }
            return queryParameters;
        },
        processResults: function (data) {
            return {
                results: $.map(data, function (item) {
                    return {
                        text: item.tag_value,
                        id: item.tag_id
                    }
                })
            };
        }
    }
});

@jason-mccreary is totally right. Besides I recommend you this code to get more info in case of malfunction:

$rest = curl_exec($crl);

if ($rest === false)
{
    // throw new Exception('Curl error: ' . curl_error($crl));
    print_r('Curl error: ' . curl_error($crl));
}

curl_close($crl);
print_r($rest);

EDIT 1

To debug you can set CURLOPT_HEADER to true to check HTTP response with firebug::net or similar.

curl_setopt($crl, CURLOPT_HEADER, true);

EDIT 2

About Curl error: SSL certificate problem, verify that the CA cert is OK try adding this headers (just to debug, in a production enviroment you should keep these options in true):

curl_setopt($crl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($crl, CURLOPT_SSL_VERIFYPEER, false);

shlex has a .split() function. It differs from str.split() in that it does not preserve quotes and treats a quoted phrase as a single word:

>>> import shlex
>>> shlex.split("sudo echo 'foo && bar'")
['sudo', 'echo', 'foo && bar']

NB: it works well for Unix-like command line strings. It doesn't work for natural-language processing.

ChangeDetectorRef.detectChanges() is usually the most focused way of doing this. ApplicationRef.tick() is usually too much of a sledgehammer approach.

To use ChangeDetectorRef.detectChanges(), you'll need this at the top of your component:

import {  ChangeDetectorRef } from '@angular/core';

... then, usually you alias that when you inject it in your constructor like this:

constructor( private cdr: ChangeDetectorRef ) { ... }

Then, in the appropriate place, you call it like this:

this.cdr.detectChanges();

Where you call ChangeDetectorRef.detectChanges() can be highly significant. You need to completely understand the life cycle and exactly how your application is functioning and rendering its components. There's no substitute here for completely doing your homework and making sure you understand the Angular lifecycle inside out. Then, once you understand that, you can use ChangeDetectorRef.detectChanges() appropriately (sometimes it's very easy to understand where you should use it, other times it can be very complex).

And multiple concatenation:

from django import template
register = template.Library()


@register.simple_tag
def concat_all(*args):
    """concatenate all args"""
    return ''.join(map(str, args))

And in Template:

{% concat_all 'x' 'y' another_var as string_result %}
concatenated string: {{ string_result }}

Thanks to @LyphTEC that gave a very interesting way to open an Office file in edit mode!

It gave me the idea to change the function _DispEx that is called when the user clicks on a file into a document library. By hacking the original function we can them be able to open a dialog (for Firefox/Chrome) and ask the user if he/she wants to readonly or edit the file:

See below the JavaScript code I used. My code is for Excel files, but it could be modified to work with Word documents too:

    /**
 * fix problem with Excel documents on Firefox/Chrome (see https://blog.kodono.info/wordpress/2017/02/09/how-to-open-an-excel-document-from-sharepoint-files-into-chromefirefox-in-readonlyedit-mode/)
 * @param  {HTMLElement} p the <A> element
 * @param  {HTMLEvent} a the click event
 * @param  {Boolean} h TRUE
 * @param  {Boolean} e FALSE
 * @param  {Boolean} g FALSE
 * @param  {Strin} k the ActiveX command (e.g. "SharePoint.OpenDocuments.3")
 * @param  {Number} c 0
 * @param  {String} o the activeX command, here we look at "SharePoint.OpenDocuments"
 * @param  {String} m
 * @param  {String} b the replacement URL to the xslviewer

I use SP.SOD.executeOrDelayUntilEventNotified to make sure the function will be executed when core.js is loaded.

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

You need to specify the domain:

 $('.button1').click(function() {
   window.location = 'www.example.com/index.php?id=' + this.id;
 });

Alt simplification of https://stackoverflow.com/users/1969435/gx1sptdtda above:

cond <-c(1,2,3)
rating <-c(100,200,300)
df <- data.frame(cond, rating)
df
  cond rating
1    1    100
2    2    200
3    3    300

A byte with a value of 0x00 is, on the ASCII table, the special character called NUL or NULL. In C, since you shouldn't embed control characters in your source code, this is represented in C strings with an escaped 0, i.e., \0.

But a true NULL is not a value. It is the absence of a value. For a pointer, it means the pointer has nothing to point to. In a database, it means there is no value in a field (which is not the same thing as saying the field is blank, 0, or filled with spaces).

The actual value a given system or database file format uses to represent a NULL isn't necessarily 0x00.

You can just change the data-original-title using the following code:

$(element).attr('data-original-title', newValue);

My way

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.beans.BeanInfo;
import java.beans.Introspector;
import java.beans.PropertyDescriptor;

public class ReadAnnotation {
    private static final Logger LOGGER = LoggerFactory.getLogger(ReadAnnotation.class);

    public static boolean hasIgnoreAnnotation(String fieldName, Class entity) throws NoSuchFieldException {
        return entity.getDeclaredField(fieldName).isAnnotationPresent(IgnoreAnnotation.class);
    }

    public static boolean isSkip(PropertyDescriptor propertyDescriptor, Class entity) {
        boolean isIgnoreField;
        try {
            isIgnoreField = hasIgnoreAnnotation(propertyDescriptor.getName(), entity);
        } catch (NoSuchFieldException e) {
            LOGGER.error("Can not check IgnoreAnnotation", e);
            isIgnoreField = true;
        }
        return isIgnoreField;
    }

    public void testIsSkip() throws Exception {
        Class<TestClass> entity = TestClass.class;
        BeanInfo beanInfo = Introspector.getBeanInfo(entity);

        for (PropertyDescriptor propertyDescriptor : beanInfo.getPropertyDescriptors()) {
            System.out.printf("Field %s, has annotation %b", propertyDescriptor.getName(),  isSkip(propertyDescriptor, entity));
        }
    }

}

Even though you didn't provide enough information to answer this question properly, your best shots are SSH tunnels (or reverse SSH tunnels).

You only need one SSH server on your internal or remote network to provide access to your local machine.

You can use PUTTY (it has a GUI) on Windows to create your tunnel.

Updating firebase initialization works for me..

<script src="https://www.gstatic.com/firebasejs/4.6.2/firebase.js"></script>
 <script>
  // Initialize Firebase
  // TODO: Replace with your project's customized code snippet
  var config = {
    apiKey: "<API_KEY>",
    authDomain: "<PROJECT_ID>.firebaseapp.com",
    databaseURL: "https://<DATABASE_NAME>.firebaseio.com",
    storageBucket: "<BUCKET>.appspot.com",
    messagingSenderId: "<SENDER_ID>",
  };
  firebase.initializeApp(config);
</script>

Add an href attribute to make it a valid link & return false; in the event handler to prevent it from causing a navigation;

<a href="#" class="menu_links" onclick="displayData(11,1,0,'A'); return false;" onmouseover=""> A </a>

(Or make displayData() return false and ..="return displayData(..)

This should work. But I have same problems on an Android phone.

<input type="number" /> <input type="tel" />

I found out, that if I didn't include the jquerymobile-framework, the keypad showed correctly on the two types of fields.

But I havn't found a solution to solve that problem, if you really need to use jquerymobile.

UPDATE: I found out, that if the form-tag is stored out of the

<div data-role="page"> 

The number keypad isn't shown. This must be a bug...

It only seems to because that is what it is printing out. But actually, you shouldn't write the logic this way. This is equivalent:

insert into errortable (dateupdated, table1id)
    values (sysdate, 1083);

It seems silly to convert the system date to a string just to convert it back to a date.

If you want to see the full date, then you can do:

select TO_CHAR(dateupdated, 'YYYY-MM-DD HH24:MI:SS'), table1id
from errortable;

Double quotes option helped me

SET QUOTED_IDENTIFIER OFF;
insert into my_table values("hi, my name's tim.");
SET QUOTED_IDENTIFIER ON;

Several other answer give the solution using MAX. In some scenarios using an agregate function is either not possilbe, or not performant.

The alternative that I use a lot is to use a correlated sub-query in the join...

SELECT
   `userName`,
   `carPrice`
FROM `users`
LEFT JOIN `cars`
ON cars.id = (
  SELECT id FROM `cars` WHERE BelongsToUser = users.id ORDER BY carPrice DESC LIMIT 1
)
WHERE `id`='4'

You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task or Task<T>, if you return nothing and you want your method will be run asyncronously you should define your method like this:

private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } 

And in Main method you can't await for DoDownloadAsync, because you can't use await keyword in non-async function, and you can't make Main async. So consider this:

var result = DoDownloadAsync();  Debug.WriteLine("DoDownload done"); result.Wait(); 

The big difference between Bootstrap 2 and Bootstrap 3 is that Bootstrap 3 is "mobile first".

That means the default styles are designed for mobile devices and in the case of Navbars, that means it's "collapsed" by default and "expands" when it reaches a certain minimum size.

Bootstrap 3's site actually has a "hint" as to what to do: http://getbootstrap.com/components/#navbar

Customize the collapsing point

Depending on the content in your navbar, you might need to change the point at which your navbar switches between collapsed and horizontal mode. Customize the @grid-float-breakpoint variable or add your own media query.

If you're going to re-compile your LESS, you'll find the noted LESS variable in the variables.less file. It's currently set to "expand" @media (min-width: 768px) which is a "small screen" (ie. a tablet) by Bootstrap 3 terms.

@grid-float-breakpoint: @screen-tablet;

If you want to keep the collapsed a little longer you can adjust it like such:

@grid-float-breakpoint: @screen-desktop; (992px break-point)

or expand sooner

@grid-float-breakpoint: @screen-phone (480px break-point)

If you want to have it expand later, and not deal with re-compiling the LESS, you'll have to overwrite the styles that get applied at the 768px media query and have them return to the previous value. Then re-add them at the appropriate time.

I'm not sure if there's a better way to do it. Recompiling the Bootstrap LESS to your needs is the best (easiest) way. Otherwise, you'll have to find all the CSS media queries that affect your Navbar, overwrite them to default styles @ the 768px width and then revert them back at a higher min-width.

Recompiling the LESS will do all that magic for you just by changing the variable. Which is pretty much the point of LESS/SASS pre-compilers. =)

(note, I did look them all up, it's about 100 lines of code, which is annoy enough for me to drop the idea and just re-compile Bootstrap for a given project and avoid messing something up by accident)

I hope that helps!

Cheers!

Well, you should also try adding the Javascript code into a function, then calling the function after document body has loaded..it worked for me :)

In case you want to match multiple words to your magic word, you can pass the words to match as a tuple:

>>> magicWord = 'zzzTest'
>>> magicWord.startswith(('zzz', 'yyy', 'rrr'))
True

startswith takes a string or a tuple of strings.

The second way is as to respond to the HTTP OPTIONS verb in your BeginRequest method.

  protected void Application_BeginRequest(object sender, EventArgs e)
{
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
    if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
    {
        HttpContext.Current.Response.AddHeader("Access-Control-Request-Method", "GET ,POST, PUT, DELETE");

        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Origin,Content-Type, Accept");
        HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "86400"); // 24 hours
        HttpContext.Current.Response.End();
    }
}

On windows those guys using xampp should use this path xampp/mysql/bin/my.ini and change max_allowed_packet(under section[mysqld])to your choice size. e.g

max_allowed_packet=8M

Again on php.ini(xampp/php/php.ini) change upload_max_filesize the choice size. e.g

upload_max_filesize=8M

Gave me a headache for sometime till i discovered this. Hope it helps.

its just simple

  select * from myTable where year(columnX) = 2010

This command might come in handy. This will not record the command that is executed

history -d $((HISTCMD-1)) && <Your Command Here>

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them

Just for sake of completeness, you can also use the same technique above with excel tables.

In the example below, I'm looking of a text in any cell of a Excel Table named "tblConfig", place in the sheet named Config that normally is set to be hidden. I'm accepting the defaults of the Find method.

Dim list As ListObject
Dim config As Worksheet
Dim cell as Range


Set config = Sheets("Config")
Set list = config.ListObjects("tblConfig")

'search in any cell of the data range of excel table
Set cell = list.DataBodyRange.Find(searchTerm)

If cell Is Nothing Then
    'when information is not found
Else
    'when information is found
End If

After removing the innodb_additional_mem_pool_size=4M from my.ini and killing that process that used the port that Mysql wanted I managed it to go.

Suggested fix: 1) The quick solution: Comment the line innodb_additional_mem_pool_size=4M in the service's 'my.ini' file, 2) exclude the option from the 5.7.4 default config file or 3) un-unknow the variable to mysql ;)

link: http://bugs.mysql.com/bug.php?id=72533

Use number 1, remove the whole line. Save to my.ini. Kill the process if you have one running (look at them with resmon.exe and kill them with command taskkill /pid pid-of-process /f), then start wampmysql and your icon should turn green.

sudo apt-get update
sudo apt-get  install openjdk-8-jdk

this should work

Make sure that the dependent dll used by you does not have target .net framework higher than the target .net framework of your project's Application.

You can check this by selecting your project, then press ALT+ENTER, then select Application from left side and then select Target Framework of your project.

Suppose, dependent dll Target Framework = 4.0 and Application dll Target Framework = 3.5 then change this to 4.0

Thank you!

user Jochen Ritzel said this in a comment to an answer to this question from user dappawit. It should work:

('1' in var) and ('2' in var) and ('3' in var) ...

'1', '2', etc. should be replaced with the characters you are looking for.

See this page in the Python 2.7 documentation for some information on strings, including about using the in operator for substring tests.

Update: This does the same job as my above suggestion with less repetition:

# When looking for single characters, this checks for any of the characters...
# ...since strings are collections of characters
any(i in '<string>' for i in '123')
# any(i in 'a' for i in '123') -> False
# any(i in 'b3' for i in '123') -> True

# And when looking for subsrings
any(i in '<string>' for i in ('11','22','33'))
# any(i in 'hello' for i in ('18','36','613')) -> False
# any(i in '613 mitzvahs' for i in ('18','36','613')) ->True

This works without needing jQuery:

var textArea = document.getElementById("my-text-area");
var arrayOfLines = textArea.value.split("\n"); // arrayOfLines is array where every element is string of one line

Use this line of code when scanning the second value: scanf(" %lf", &b); also replace all %ld with %lf.

It's a problem related with input stream buffer. You can also use fflush(stdin); after the first scanning to clear the input buffer and then the second scanf will work as expected. An alternate way is place a getch(); or getchar(); function after the first scanf line.

Have you tried :

hadoop dfs -rmr hdfs://host:port/Navi/MyDir\,\ Name?

Since you are using an INNER JOIN you can just put the conditions in the WHERE clause, like this:

SELECT 
    p1.kArtikel, 
    p1.cName, 
    p1.cKurzBeschreibung, 
    p1.dLetzteAktualisierung, 
    p1.dErstellt, 
    p1.cSeo,
    p2.kartikelpict,
    p2.nNr,
    p2.cPfad  
FROM 
    tartikel AS p1 INNER JOIN tartikelpict AS p2 
    ON p1.kArtikel = p2.kArtikel
WHERE
  DATE(dErstellt) > (NOW() - INTERVAL 7 DAY)
  AND p2.nNr = 1
ORDER BY 
  p1.kArtikel DESC
LIMIT
    100;

I ran into this because I made a copy-and-paste of ngBoilerplate into my project on a Mac without Finder showing hidden files. So .bower was not copied with the rest of ngBoilerplate. Thus bower moved resources to bower_components (defult) instead of vendor (as configured) and my app didn't get angular. Probably a corner case, but it might help someone here.

The accepted answer didn't perform that well for me (I'd hold a key, nothing would happen, then I'd press another key and it would work).

After learning about the curses module, it really seems like the right way to go. And it's now available for Windows through windows-cursors (available through pip), so you can program in a platform agnostic manner. Here's an example inspired by this nice tutorial on YouTube:

import curses                                                                                                                                       
def getkey(stdscr):
    curses.curs_set(0)
    while True:
        key = stdscr.getch()
        if key != -1:
            break
    return key

if __name__ == "__main__":
    print(curses.wrapper(getkey))

Save it with a .py extension, or run curses.wrapper(getkey) in interactive mode.

The use of the argument, conventionally called self isn't as hard to understand, as is why is it necessary? Or as to why explicitly mention it? That, I suppose, is a bigger question for most users who look up this question, or if it is not, they will certainly have the same question as they move forward learning python. I recommend them to read these couple of blogs:

1: Use of self explained

Note that it is not a keyword.

The first argument of every class method, including init, is always a reference to the current instance of the class. By convention, this argument is always named self. In the init method, self refers to the newly created object; in other class methods, it refers to the instance whose method was called. For example the below code is the same as the above code.

2: Why do we have it this way and why can we not eliminate it as an argument, like Java, and have a keyword instead

Another thing I would like to add is, an optional self argument allows me to declare static methods inside a class, by not writing self.

Code examples:

class MyClass():
    def staticMethod():
        print "This is a static method"

    def objectMethod(self):
        print "This is an object method which needs an instance of a class, and that is what self refers to"

PS:This works only in Python 3.x.

In previous versions, you have to explicitly add @staticmethod decorator, otherwise self argument is obligatory.

I add my Regex - i solved for me more little issues like characters from other languages or capital letters

^[a-zA-Z0-9][a-zA-Z0-9-_\.]+@([a-zA-Z]|[a-zA-Z0-9]?[a-zA-Z0-9-]+[a-zA-Z0-9])\.[a-zA-Z0-9]{2,10}(?:\.[a-zA-Z]{2,10})?$

The print() function returns None. You are trying to index None. You can not, because 'NoneType' object is not subscriptable.

Put the [0] inside the brackets. Now you're printing everything, and not just the first term.

You can simply use Substring method of C#. For ex.

string str = "1110000";
string lastFourDigits = str.Substring((str.Length - 4), 4);

It will return result 0000.

You're right that the SD Card directory is /sdcard but you shouldn't be hard coding it. Instead, make a call to Environment.getExternalStorageDirectory() to get the directory:

File sdDir = Environment.getExternalStorageDirectory();

If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:

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

In Maven project, You can build jar automatically using Maven War plugin by setting archiveClasses to true. Example below.

<plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-war-plugin</artifactId>
       <configuration>
        <archiveClasses>true</archiveClasses>
       </configuration>
</plugin>

Right: it has nothing to do with your code. I've found two valid solutions to this warning (not just disabling it). To better understand what a SourceMap is, I suggest you check out this answer, where it explains how it's something that helps you debug:

The .map files are for js and css (and now ts too) files that have been minified. They are called SourceMaps. When you minify a file, like the angular.js file, it takes thousands of lines of pretty code and turns it into only a few lines of ugly code. Hopefully, when you are shipping your code to production, you are using the minified code instead of the full, unminified version. When your app is in production, and has an error, the sourcemap will help take your ugly file, and will allow you to see the original version of the code. If you didn't have the sourcemap, then any error would seem cryptic at best.

1. First solution: apparently, Mr Heelis was the closest one: you should add the .map file and there are some tools that help you with this problem (Grunt, Gulp and Google closure for example, quoting the answer). Otherwise you can download the .map file from official sites like Bootstrap, jquery, font-awesome, preload and so on.. (maybe installing things like popper or swiper by the npm command in a random folder and copying just the .map file in your js/css destination folder)

2. Second solution (the one I used): add the source files using a CDN (here all the advantages of using a CDN). Using the Content delivery network (CDN) you can simply add the cdn link, instead of the path to your folder. You can find cdn on official websites (Bootstrap, jquery, popper, etc..) or you can easily search on some websites like cloudflare, cdnjs, etc..

This is exactly what I was looking for after finding that RedirectToAction() would not pass complex class objects.

As an example, I want to call the IndexComparison method in the LifeCycleEffectsResults controller and pass it a complex class object named model.

Here is the code that failed:

return RedirectToAction("IndexComparison", "LifeCycleEffectsResults", model);

Worth noting is that Strings, integers, etc were surviving the trip to this controller method, but generic list objects were suffering from what was reminiscent of C memory leaks.

As recommended above, here's the code I replaced it with:

var controller = DependencyResolver.Current.GetService<LifeCycleEffectsResultsController>();

var result = controller.IndexComparison(model);
return result;

All is working as intended now. Thank you for leading the way.

Update 2018-11-28:

Here is a summary of experiments with Python 2 and 3. With

main.py - runs foo.py
foo.py - runs lib/bar.py
lib/bar.py - prints filepath expressions

| Python | Run statement       | Filepath expression                    |
|--------+---------------------+----------------------------------------|
|      2 | execfile            | os.path.abspath(inspect.stack()[0][1]) |
|      2 | from lib import bar | __file__                               |
|      3 | exec                | (wasn't able to obtain it)             |
|      3 | import lib.bar      | __file__                               |

For Python 2, it might be clearer to switch to packages so can use from lib import bar - just add empty __init__.py files to the two folders.

For Python 3, execfile doesn't exist - the nearest alternative is exec(open(<filename>).read()), though this affects the stack frames. It's simplest to just use import foo and import lib.bar - no __init__.py files needed.

Original Answer:

Here is an experiment based on the answers in this thread - with Python 2.7.10 on Windows.

The stack-based ones are the only ones that seem to give reliable results. The last two have the shortest syntax, i.e. -

print os.path.abspath(inspect.stack()[0][1])                   # C:\filepaths\lib\bar.py
print os.path.dirname(os.path.abspath(inspect.stack()[0][1]))  # C:\filepaths\lib

Here's to these being added to sys as functions! Credit to @Usagi and @pablog

Based on the following three files, and running main.py from its folder with python main.py (also tried execfiles with absolute paths and calling from a separate folder).

C:\filepaths\main.py: execfile('foo.py')
C:\filepaths\foo.py: execfile('lib/bar.py')
C:\filepaths\lib\bar.py:

import sys
import os
import inspect

print "Python " + sys.version
print

print __file__                                        # main.py
print sys.argv[0]                                     # main.py
print inspect.stack()[0][1]                           # lib/bar.py
print sys.path[0]                                     # C:\filepaths
print

print os.path.realpath(__file__)                      # C:\filepaths\main.py
print os.path.abspath(__file__)                       # C:\filepaths\main.py
print os.path.basename(__file__)                      # main.py
print os.path.basename(os.path.realpath(sys.argv[0])) # main.py
print

print sys.path[0]                                     # C:\filepaths
print os.path.abspath(os.path.split(sys.argv[0])[0])  # C:\filepaths
print os.path.dirname(os.path.abspath(__file__))      # C:\filepaths
print os.path.dirname(os.path.realpath(sys.argv[0]))  # C:\filepaths
print os.path.dirname(__file__)                       # (empty string)
print

print inspect.getfile(inspect.currentframe())         # lib/bar.py

print os.path.abspath(inspect.getfile(inspect.currentframe())) # C:\filepaths\lib\bar.py
print os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe()))) # C:\filepaths\lib
print

print os.path.abspath(inspect.stack()[0][1])          # C:\filepaths\lib\bar.py
print os.path.dirname(os.path.abspath(inspect.stack()[0][1]))  # C:\filepaths\lib
print

I know this is an old question, but I stumbled upon the same problem and tried to use the function given in Alex's answer.

But the quality in the jpeg result was too low. So I changed the function a little bit to become more usable in my project and changed the "imagecopyresized" to "imagecopyresampled" (according to this recomendation).

If you are having questions about how to use this function, then try taking a look at the well documented version here.

function createThumbnail($filepath, $thumbpath, $thumbnail_width, $thumbnail_height, $background=false) {
    list($original_width, $original_height, $original_type) = getimagesize($filepath);
    if ($original_width > $original_height) {
        $new_width = $thumbnail_width;
        $new_height = intval($original_height * $new_width / $original_width);
    } else {
        $new_height = $thumbnail_height;
        $new_width = intval($original_width * $new_height / $original_height);
    }
    $dest_x = intval(($thumbnail_width - $new_width) / 2);
    $dest_y = intval(($thumbnail_height - $new_height) / 2);

    if ($original_type === 1) {
        $imgt = "ImageGIF";
        $imgcreatefrom = "ImageCreateFromGIF";
    } else if ($original_type === 2) {
        $imgt = "ImageJPEG";
        $imgcreatefrom = "ImageCreateFromJPEG";
    } else if ($original_type === 3) {
        $imgt = "ImagePNG";
        $imgcreatefrom = "ImageCreateFromPNG";
    } else {
        return false;
    }

    $old_image = $imgcreatefrom($filepath);
    $new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height); // creates new image, but with a black background

    // figuring out the color for the background
    if(is_array($background) && count($background) === 3) {
      list($red, $green, $blue) = $background;
      $color = imagecolorallocate($new_image, $red, $green, $blue);
      imagefill($new_image, 0, 0, $color);
    // apply transparent background only if is a png image
    } else if($background === 'transparent' && $original_type === 3) {
      imagesavealpha($new_image, TRUE);
      $color = imagecolorallocatealpha($new_image, 0, 0, 0, 127);
      imagefill($new_image, 0, 0, $color);
    }

    imagecopyresampled($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
    $imgt($new_image, $thumbpath);
    return file_exists($thumbpath);
}

<?php
// Initialize the session.
session_start();
// Unset all of the session variables.
unset($_SESSION['username']);
// Finally, destroy the session.    
session_destroy();

// Include URL for Login page to login again.
header("Location: login.php");
exit;
?>

The error pretty much explains what the problem is: you are trying to include a file that is not there.

Try to use the full path to the file, using realpath(), and use dirname(__FILE__) to get your current directory:

require_once(realpath(dirname(__FILE__) . '/../includes/dbconn.inc'));

There is a simple solution if you want to use px to specify font size, but still want the usability that em's provide by placing this in your CSS file:

body {
  font-size: 62.5%;
}

Now specify you p (and other) tags like this:

p {
  font-size: 0.8em; /* This is equal to 8px */
  font-size: 1.0em; /* This is equal to 10px */
  font-size: 1.2em; /* This is equal to 12px */
  font-size: 2.0em; /* This is equal to 20px */
}

And so on.

You can also pipe in the file names which might be useful:

find /path/to/files -name \*.txt | tar -cvf allfiles.tar -T -

This error is usually encountered when inserting a record in a table where one of the columns is a VARCHAR or CHAR data type and the length of the value being inserted is longer than the length of the column.

I am not satisfied how Microsoft decided to inform with this "dry" response message, without any point of where to look for the answer.

I am writing this not as a solution meant for many, but for some people who may commit a simple mistake like specifying the wrong url for importing projects from SVN. It is intended for those guys :)

This happened to me when I imported the project from SVN -> automatic prompt by Studio to open the project -> It asked for Gradle location -> D:\Software\Android\gradle-2.5 -> Then the error.

The same project in a different SVN branch works fine with the Gradle plugin and Gradle which I have configured in Studio. I tried changing Android Gradle plugin and Gradle to get it working on the erring branch without any success.

Finally, I figured out that it was my following mistake: I tried importing a specific Application alone instead of importing the application along with dependent library projects. The url which I used for import initially had the Application porject's name at the end. Once I removed it, and specified the parent directory which contained both application project and its dependent project, everything went smooth :)

Quoted from PEP 343 -- The "with" Statement (added import statement):

Redirect stdout temporarily:

import sys
from contextlib import contextmanager
@contextmanager
def stdout_redirected(new_stdout):
    save_stdout = sys.stdout
    sys.stdout = new_stdout
    try:
        yield None
    finally:
        sys.stdout = save_stdout

Used as follows:

with open(filename, "w") as f:
    with stdout_redirected(f):
        print "Hello world"

This isn't thread-safe, of course, but neither is doing this same dance manually. In single-threaded programs (for example in scripts) it is a popular way of doing things.

Not really, no.

Java doesn't have pointers. If you really wanted you could try to emulate them by building around something like reflection, but it would have all of the complexity of pointers with none of the benefits.

Java doesn't have pointers because it doesn't need them. What kind of answers were you hoping for from this question, i.e. deep down did you hope you could use them for something or was this just curiousity?

alternatively you can try this:

<?php echo (new DateTime("now", new DateTimeZone('Asia/Singapore')))->format("Y-m-d H:i:s e"); ?>

this will output :

2017-10-25 17:13:20 Asia/Singapore

you can use this inside the value attribute of a text input box if you only want to display a read-only date.

remove the 'e' if you do not wish to show your region/country.

For start Activity 2 from Activity 1 and get result, you could use startActivityForResult and implement onActivityResult in Activity 1 and use setResult in Activity2.

Intent intent = new Intent(this, Activity2.class);
intent.putExtra(NUMERO1, numero1);
intent.putExtra(NUMERO2, numero2);
//startActivity(intent);
startActivityForResult(intent, MI_REQUEST_CODE);

do you want to try the below code I found on the internet somewhere many moons ago and used.

It uses the Export function of the Chart object along with the CopyPicture method of the Range object.

References:

• MSDN - Export method as it applies to the Chart object. to save the clipboard as an Image

• MSDN - CopyPicture method as it applies to the Range object to copy the range as a picture

  dim sSheetName as string
  dim oRangeToCopy as range
  Dim oCht As Chart
  
  sSheetName ="Sheet1" ' worksheet to work on
  set  oRangeToCopy =Range("B2:H8") ' range to be copied
  
  Worksheets(sSheetName).Range(oRangeToCopy).CopyPicture xlScreen, xlBitmap
  set oCht =charts.add
  
  with oCht
      .paste
      .Export FileName:="C:\SavedRange.jpg", Filtername:="JPG"
  end with
  

I faced exactly the same issue. Calling '(!isFinishing())' prevented the crash, but it could not display the 'alert' message.

Then I tried making calling function 'static', where alert is displayed. After that, no crash happened and message is also getting displayed.

For ex:

public static void connect_failure() {      
        Log.i(FW_UPD_APP, "Connect failed");

        new AlertDialog.Builder(MyActivity)
        .setTitle("Title")
        .setMessage("Message")
        .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) { 
                  //do nothing
            }
         })
        .setIcon(R.drawable.the_image).show();      
    }

git rev-parse Also works for getting the current branch name using the --abbrev-ref flag like:

git rev-parse --abbrev-ref HEAD

The usual way would be:

if (a instanceof A)

However, there are cases when you can't do this, such as when A in a generic argument.

Due to Java's type erasure, the following won't compile:

<A> boolean someMethod(Object a) {
    if (a instanceof A)
    ...
}

and the following won't work (and will produce an unchecked cast warning):

<A> void someMethod(Object a) {
    try {
        A casted = (A)a;    
    } catch (ClassCastException e) {
         ...
    }
}

You can't cast to A at runtime, because at runtime, A is essentially Object.

The solutions to such cases is to use a Class instead of the generic argument:

void someMethod(Object a, Class<A> aClass) {
    if (aClass.isInstance(a)) {
       A casted = aClass.cast(a);
       ...
    }
}

You can then call the method as:

someMethod(myInstance, MyClass.class);
someMethod(myInstance, OtherClass.class);

It is a pretty old post, but I just had to do it today. I just right-clicked database from SQL2014 and selected Export Data option and that helped me to move data to SQL2012.

var array = $('#searchKeywords').val().split(",");

then

$.each(array,function(i){
   alert(array[i]);
});

OR

for (i=0;i<array.length;i++){
     alert(array[i]);
}

What about something like this, without a button:

<input type="text" placeholder="Search..." [value]="searchValue" onblur="this.value=''">

Using select2 jquery library:

$('#selector').val(arrayOfValues).trigger('change')

Remove the get_figure and just use sns_plot.savefig('output.png')

df = sns.load_dataset('iris')
sns_plot = sns.pairplot(df, hue='species', height=2.5)
sns_plot.savefig("output.png")

Works ok for me:

$('a.popup-ajax').popover({
    "html": true,
    "content": function(){
        var div_id =  "tmp-id-" + $.now();
        return details_in_popup($(this).attr('href'), div_id);
    }
});

function details_in_popup(link, div_id){
    $.ajax({
        url: link,
        success: function(response){
            $('#'+div_id).html(response);
        }
    });
    return '<div id="'+ div_id +'">Loading...</div>';
}

Use the IP instead:

DROP USER 'root'@'127.0.0.1'; GRANT ALL PRIVILEGES ON . TO 'root'@'%';

For more possibilities, see this link.

To create the root user, seeing as MySQL is local & all, execute the following from the command line (Start > Run > "cmd" without quotes):

mysqladmin -u root password 'mynewpassword'

Watch for filenames in italic

Note that, the file name on the tab is formatted in italic if it has been opened in Preview Mode.

Quickly take a file out of Preview Mode

To keep the file always available in VSCode editor (that is, to take it out of Preview Mode into normal mode), you can double-click on the tab. Then, you will notice the name becomes non-italic.

Feature or bug?

I believe Preview Mode is helpful especially when you have limited screen space and need to check many files.

I have never used jekyll, but it's main page says that it uses Liquid, and according to their docs, I think the following should work:

<ul> {% for page in site.pages %}     {% if page.title != 'index' %}     <li><div class="drvce"><a href="{{ page.url }}">{{ page.title }}</a></div></li>     {% endif %} {% endfor %} </ul> 

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

Expanding on @Avenir Çokaj's answer

Being a novice even I did not understand the error message clearly at first.

What the error message indicates is that in your formGroup you have an element that doesn't get accounted for in your formControl. (Intentionally/Accidentally)

If you intend on not validating this field but still want to use the ngModel on this input element please add the flag to indicate it's a standalone component without a need for validation as mentioned by @Avenir above.

You can create the ordered dict from old dict in one line:

from collections import OrderedDict
ordered_dict = OrderedDict(sorted(ship.items())

The default sorting key is by dictionary key, so the new ordered_dict is sorted by old dict's keys.

From w3school's page on JavaScript output,

JavaScript can "display" data in different ways:

Writing into an alert box, using window.alert().

Writing into the HTML output using document.write().

Writing into an HTML element, using innerHTML.

Writing into the browser console, using console.log().

I've just created a little example showing how to implement commands in convention over configuration style. However it requires Reflection.Emit() to be available. The supporting code may seem a little weird but once written it can be used many times.

Teaser:

public class SampleViewModel: BaseViewModelStub
{
    public string Name { get; set; }

    [UiCommand]
    public void HelloWorld()
    {
        MessageBox.Show("Hello World!");
    }

    [UiCommand]
    public void Print()
    {
        MessageBox.Show(String.Concat("Hello, ", Name, "!"), "SampleViewModel");
    }

    public bool CanPrint()
    {
        return !String.IsNullOrEmpty(Name);
    }
}

}

UPDATE: now there seem to exist some libraries like http://www.codeproject.com/Articles/101881/Executing-Command-Logic-in-a-View-Model that solve the problem of ICommand boilerplate code.

One interesting approach is to cast CString to CStringA inside a string constructor. Unlike std::string s((LPCTSTR)cs); this will work even if _UNICODE is defined. However, if that is the case, this will perform conversion from Unicode to ANSI, so it is unsafe for higher Unicode values beyond the ASCII character set. Such conversion is subject to the _CSTRING_DISABLE_NARROW_WIDE_CONVERSION preprocessor definition. https://msdn.microsoft.com/en-us/library/5bzxfsea.aspx

        CString s1("SomeString");
        string s2((CStringA)s1);

from selenium import webdriver

PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=%s' % PROXY)

chrome = webdriver.Chrome(options=chrome_options)
chrome.get("http://whatismyipaddress.com")

You can use the following code for your requirement

map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

Thank you for this example, SPRBRN. It helped me. And I can suggest the mixin, which I've used based on the code given above:

//multi-column-list( fixed columns width)
  @mixin multi-column-list($column-width, $column-rule-style) {
  -webkit-column-width: $column-width;
  -moz-column-width: $column-width;
  -o-column-width: $column-width;
  -ms-column-width: $column-width;
  column-width: $column-width;

  -webkit-column-rule-style: $column-rule-style;
  -moz-column-rule-style: $column-rule-style;
  -o-column-rule-style: $column-rule-style;
  -ms-column-rule-style: $column-rule-style;
  column-rule-style: $column-rule-style;
 }

Using:

   @include multi-column-list(250px, solid);

TL;DR: When using functional idioms it's better to write functional code

As many people have pointed out, in Python lambdas assignment is not allowed. In general when using functional idioms your better off thinking in a functional manner which means wherever possible no side effects and no assignments.

Here is functional solution which uses a lambda. I've assigned the lambda to fn for clarity (and because it got a little long-ish).

from operator import add
from itertools import ifilter, ifilterfalse
fn = lambda l, pred: add(list(ifilter(pred, iter(l))), [ifilterfalse(pred, iter(l)).next()])
objs = [Object(name=""), Object(name="fake_name"), Object(name="")]
fn(objs, lambda o: o.name != '')

You can also make this deal with iterators rather than lists by changing things around a little. You also have some different imports.

from itertools import chain, islice, ifilter, ifilterfalse
fn = lambda l, pred: chain(ifilter(pred, iter(l)), islice(ifilterfalse(pred, iter(l)), 1))

You can always reoganize the code to reduce the length of the statements.

I got a similar error (Incorrect string value: '\xD0\xBE\xDO\xB2. ...' for 'content' at row 1). I have tried to change character set of column to utf8mb4 and after that the error has changed to 'Data too long for column 'content' at row 1'.
It turned out that mysql shows me wrong error. I turned back character set of column to utf8 and changed type of the column to MEDIUMTEXT. After that the error disappeared.
I hope it helps someone.
By the way MariaDB in same case (I have tested the same INSERT there) just cut a text without error.

Because the break statement is intended to break out of loops. You don't need to break out of an if statement - it just ends at the end.

Public Function TestError() As String()
     Return {"foo", "bar"}
End Function

Works fine for me and should work for you, but you may need allow using implicit declarations in your project. I believe this is turning off Options strict in the Compile section of the program settings.

Since you are using VS 2008 (VB.NET 9.0) you have to declare create the new instance

New String() {"foo", "Bar"}

Client side Upload Canceling

On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE, can be tampered with so always use server side validation.

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input type="file" name="file" id="file" />
    <input type="submit" name="submit" value="Submit" />
</form>

<script>
document.forms[0].addEventListener('submit', function( evt ) {
    var file = document.getElementById('file').files[0];

    if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
        //Submit form        
    } else {
        //Prevent default and display error
        evt.preventDefault();
    }
}, false);
</script>

Server Side Upload Canceling

On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.

PHP Validation

On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES array to find out the upload size. (Docs on the contents of $_FILES can be found below the MAX_FILE_SIZE docs)

upload.php

<?php
if(isset($_FILES['file'])) {
    if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
        // File too big
    } else {
        // File within size restrictions
    }
}

I had the same issue. After changing a semicolon in the php.ini file I solved my problem. Let's see how can you solve it?

First, open php.ini file. xampp/php/php.ini

Search extension=imap

remove semicolon before extension and save this file.

Code before remove semicolon ;extension=imap

Code after remove semicolon extension=imap

Finally, open the XAMPP Control panel and restart Apache.

Tell PDO your charset initially.... something like

PDO("mysql:host=$host;dbname=$DB_name;charset=utf8;", $username, $password);

Notice the: charset=utf8; part.

hope it helps!

What I do is I try to reset hard to HEAD. This will wipe out all the local commits:

git reset --hard HEAD^

To easily manipulate URLs / path / params / etc., you can use Spring's UriComponentsBuilder class. It's cleaner than manually concatenating strings and it takes care of the URL encoding for you:

HttpHeaders headers = new HttpHeaders();
headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);

UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(url)
        .queryParam("msisdn", msisdn)
        .queryParam("email", email)
        .queryParam("clientVersion", clientVersion)
        .queryParam("clientType", clientType)
        .queryParam("issuerName", issuerName)
        .queryParam("applicationName", applicationName);

HttpEntity<?> entity = new HttpEntity<>(headers);

HttpEntity<String> response = restTemplate.exchange(
        builder.toUriString(), 
        HttpMethod.GET, 
        entity, 
        String.class);

LPAD works with VARCHAR2 as it does not put spaces for left over bytes. LPAD changes leftover/null bytes to zeros on LHS SO datatype should be VARCHAR2

In Html you can add your input field with a date picker like this

<input class="form-control date-picker fromDates" id="myDate" type="text">

and then in java script, initialize your datepicker and set your value to the date like this,

$('.fromDates').datepicker({
                maxDate: '0',
                dateFormat: "dd/mm/yy",
                changeYear: true,
                changeMonth: true,
                yearRange: "-100:+0"
            });

var myDateVal = moment('${value}').format('DD/MM/YYYY');
$('#myDate').datepicker().datepicker('setDate', myDateVal );

(In here fromdate attribute shows the previous dates of the current date)

could you please try below code

<c:forEach var="hash" items="${map['key']}">
        <option><c:out value="${hash}"/></option>
  </c:forEach>

This works for me. use MAX(CONVERT(date, ReportDate)) to make sure you have date value

select max( CONVERT(date, ReportDate)) FROM [TraxHistory]

This is working for me:

this.listCopy = Object.assign([], this.list);

It often ends up being easier to load your data into the database, even if it is only to run a quick query. Hard-coded data seems quick to enter, but it quickly becomes a pain if you start having to make changes.

However, if you want to code the names directly into your query, here is a cleaner way to do it:

with names (fname,lname) as (
    values
        ('John','Smith'),
        ('Mary','Jones')
)
select city from user
    inner join names on
        fname=firstName and
        lname=lastName;

The advantage of this is that it separates your data out of the query somewhat.

(This is DB2 syntax; it may need a bit of tweaking on your system).

How about you store it like this? Maybe in username:password format, so

sebastion:password123
anotheruser:password321

Then you can use list($username,$password) = explode(':',file_get_contents('users.txt')); to parse the data on your end.

I have been confronted with the same problem, so I went to :

/xampp/phpmyadmin/config.inc.php

I pasted the password which I had enter earlier then I was able to access phpmyadmin again, there in the privileges tab/ edit/ I chose no password and go then it all came back to life :)

Also you can change the user to admin but your phpmyadmin would be in admin side and your other localhost website will not work either.

Set 'center_horizontal' and 'center_vertical' or just 'center' of the layout_gravity attribute of the widget

    <?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MovieActivity"
    android:id="@+id/mainContainerMovie"
    >


    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#3a3f51b5"
       />

    <ProgressBar
        android:id="@+id/movieprogressbar"
        style="?android:attr/progressBarStyle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical|center_horizontal" />
</FrameLayout>

This query stands good for fetching the values between current date and its next 3 dates

SELECT * FROM tableName  WHERE columName 
BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)

This will eventually add extra 3 days of buffer to the current date.

6 years later... I found this post and I liked more the numpy aproach:

import numpy as np
dates_array = np.array(['2013-01-01', '2013-01-15', '2013-01-30']).astype('datetime64[ns]')
truncated_dates = dates_array.astype('datetime64[D]')

cheers

An easy solution which avoids looping over the ticklabes is to just use

fig.autofmt_xdate()

This command automatically rotates the xaxis labels and adjusts their position. The default values are a rotation angle 30° and horizontal alignment "right". But they can be changed in the function call

fig.autofmt_xdate(bottom=0.2, rotation=30, ha='right')

The additional bottom argument is equivalent to setting plt.subplots_adjust(bottom=bottom), which allows to set the bottom axes padding to a larger value to host the rotated ticklabels.

So basically here you have all the settings you need to have a nice date axis in a single command.

A good example can be found on the matplotlib page.

1.THE USE OF {}:

It initialize the array with the values { }

2.The difference between String array=new String[]; and String array=new String[]{};

String array=new String[]; and String array=new String[]{}; both are invalid statement in java.

It will gives you an error that you are trying to assign String array to String datatype. More specifically error is like this Type mismatch: cannot convert from String[] to String

3.String array=new String[10]{}; got error why?

Wrong because you are defining an array of length 10 ([10]), then defining an array of length String[10]{} 0

Today I was trying same in db2 and used below, in my case I had spaces at the end of varchar column data

SELECT EmployeeName FROM EmployeeTable WHERE LENGTH(TRIM(EmployeeName))> 4;

list.clear() is going to keep the same ArrayList but the same memory allocation. list = new ArrayList<int>(); is going to allocate new memory for your ArrayList.

The big difference is that ArrayLists will expand dynamically as you need more space. Therefore, if you call list.clear() you will still, potentially, have a large amount of memory allocated for an ArrayList that might not be needed.

That said list.clear() will be faster but if memory maters you might want to allocate a new ArrayList.

In my case, I read the registry that npm using:

 npm config get registry

and I got

http://registry.npmjs.org/

then I had just changed http to https like this:

npm config set registry https://registry.npmjs.org/

Should you want to clear the array with something other than a value, std::file wont cut it; instead I found std::generate useful. e.g. I had a vector of lists I wanted to initialize

std::generate(v.begin(), v.end(), [] () { return std::list<X>(); });

You can do ints too e.g.

std::generate(v.begin(), v.end(), [n = 0] () mutable { return n++; });

or just

std::generate(v.begin(), v.end(), [] (){ return 0; });

but I imagine std::fill is faster for the simplest case

Perhaps you can check it here for the LATEST version always

If your application is 32 bit, and you want to deploy in a 64 bit machine, You need to set 'Enable 32 Bit Applications' property to 'True' in the application pool - advanced settings.

I think you need to use the Run/Debug Configuration item on the toolbar. Click it and 'Edit Configurations' (or alternatively use the menu item Run->Edit Configurations). In the 'Defaults' section in the left pane there is a 'py.test' item which I think is what you want.

I also found that the manual didn't match up to the UI for this. Hope I've understood the problem correctly and that helps.

Sharing my solution, because I was not completely satisfied with the rest. My problem with AfterViewChecked is that sometimes I'm scrolling up, and for some reason, this life hook gets called and it scrolls me down even if there were no new messages. I tried using OnChanges but this was an issue, which lead me to this solution. Unfortunately, using only DoCheck, it was scrolling down before the messages were rendered, which was not useful either, so I combined them so that DoCheck is basically indicating AfterViewChecked if it should call scrollToBottom.

Happy to receive feedback.

export class ChatComponent implements DoCheck, AfterViewChecked {

    @Input() public messages: Message[] = [];
    @ViewChild('scrollable') private scrollable: ElementRef;

    private shouldScrollDown: boolean;
    private iterableDiffer;

    constructor(private iterableDiffers: IterableDiffers) {
        this.iterableDiffer = this.iterableDiffers.find([]).create(null);
    }

    ngDoCheck(): void {
        if (this.iterableDiffer.diff(this.messages)) {
            this.numberOfMessagesChanged = true;
        }
    }

    ngAfterViewChecked(): void {
        const isScrolledDown = Math.abs(this.scrollable.nativeElement.scrollHeight - this.scrollable.nativeElement.scrollTop - this.scrollable.nativeElement.clientHeight) <= 3.0;

        if (this.numberOfMessagesChanged && !isScrolledDown) {
            this.scrollToBottom();
            this.numberOfMessagesChanged = false;
        }
    }

    scrollToBottom() {
        try {
            this.scrollable.nativeElement.scrollTop = this.scrollable.nativeElement.scrollHeight;
        } catch (e) {
            console.error(e);
        }
    }

Please be aware that the examples for icon file path tend to assume that main.js is under the base directory. If the file is not in the base directory of the app, the path specification must account for that fact.

For example, if the main.js is under the src/ subdirectory, and the icon is under assets/icons/, this icon path specification will work:

icon: __dirname + "../assets/icons/icon.png"

A while ago I found a VB bas module that used DMO and VSS objects to get an entire db scripted off and into VSS. I turned it into a VB Script and posted it here. You can easily take out the VSS calls and use the DMO stuff to generate all the scripts, and then call SVN from the same batch file that calls the VBScript to check them in.

Easy way to fill the missing values:-

filling string columns: when string columns have missing values and NaN values.

df['string column name'].fillna(df['string column name'].mode().values[0], inplace = True)

filling numeric columns: when the numeric columns have missing values and NaN values.

df['numeric column name'].fillna(df['numeric column name'].mean(), inplace = True)

filling NaN with zero:

df['column name'].fillna(0, inplace = True)

JS:

function fun(obj) {
    var uid= $(obj).data('uid');
    var name= $(obj).data('name');
    var value= $(obj).data('value');
}

So, I created an interface

public interface OnBackPressedListener {
    void onBackPressed();
}

And implemented it by all fragments that need to handle back button. In main activity I overrided onBackPressed() method:

@Override
public void onBackPressed() {
    final Fragment currentFragment = mNavHostFragment.getChildFragmentManager().getFragments().get(0);
    final NavController controller = Navigation.findNavController(this, R.id.nav_host_fragment);
    if (currentFragment instanceof OnBackPressedListener)
        ((OnBackPressedListener) currentFragment).onBackPressed();
    else if (!controller.popBackStack())
        finish();

}

So, If the top fragment of my Navigation host implements OnBackPressedListener interface, I call its onBackPressed() method, elsewhere I simply pop back stack and close application if the back stack is empty.

Thought I'd add to this a potential other solution:

<tr style='visibility:collapse'><td>stuff</td></tr>

I've only tested it on Chrome but putting this on the <tr> hides the row PLUS all the cells inside the row still contribute to the widths of the columns. I will sometimes make an extra row at the bottom of a table with just some spacers that make it so certain columns can't be less than a certain width, then hide the row using this method. (I know you're supposed to be able to do this with other css but I've never gotten that to work)

Again, I'm in a purely chrome environment so I have no idea how this functions in other browsers.

I didn't find the suggestion to use UIButton in the answers above. So I will try to prove that this is a good choice.

button.contentEdgeInsets = UIEdgeInsets(top: 0, left: 8, bottom: 0, right: 8)

In my situation using UIButton was the best solution because:

• I had a simple single-line text
• I didn't want to use UIView as a container for UILabel (i.e. I wanted to simplify math calculations for Autolayout in my cell)
• I didn't want to use NSParagraphStyle (because tailIndent works incorrect with Autolayout – width of UILabel is smaller than expected)
• I didn't want to use UITextView (because of possible side effects)
• I didn't want to subclass UILabel (less code fewer bugs)

That's why using the contentEdgeInsets from UIButton in my situation became the easiest way to add text margins.

Hope this will help someone.

Just do a simple .keys()

>>> dct = {
...     "1": "a", 
...     "3": "b", 
...     "8": {
...         "12": "c", 
...         "25": "d"
...     }
... }
>>> 
>>> dct.keys()
['1', '8', '3']
>>> for key in dct.keys(): print key
...
1
8
3
>>>

If you need a sorted list:

keylist = dct.keys()
keylist.sort()

As detailed by other answers here, the best solution I found is using OpenSSL. It is built into PHP and you don't need any external library. Here are simple examples:

To encrypt:

function encrypt($key, $payload) {
  $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cbc'));
  $encrypted = openssl_encrypt($payload, 'aes-256-cbc', $key, 0, $iv);
  return base64_encode($encrypted . '::' . $iv);
}

To decrypt:

function decrypt($key, $garble) {
    list($encrypted_data, $iv) = explode('::', base64_decode($garble), 2);
    return openssl_decrypt($encrypted_data, 'aes-256-cbc', $key, 0, $iv);
}

To put the strings "l" and "vv" on separate lines in the code alone:

$xml = "l";
$xml .= "vv"
echo $xml;

In this instance you're saying to append .= the string to the end of the previous version of that string variable. Remember that = is only an assignment operator so in your original code you're assigning the variable a new string value.

To put the strings "l" and "vv" on separate lines in the echo alone:

$xml = "l\nvv"
echo $xml;

You don't need multiple strings in this instance, as the new line character \n will take care of that for you.

To put the strings "l" and "vv" on separate lines in code and when echoing:

$xml = "l";
$xml .= "\nvv"
echo $xml;

This is because PHP uses the period character . for string concatenation, not the plus character +. Therefore to append to a string you want to use the .= operator:

for ($i=1;$i<=100;$i++)
{
    $selectBox .= '<option value="' . $i . '">' . $i . '</option>';
}
$selectBox .= '</select>';

Use pgrep - available on many platforms:

kill -9 `pgrep -f cps_build`

pgrep -f will return all PIDs with coincidence "cps_build"

There is now a "native" solution on Windows 10, after enabling Bash on Windows, you can enter Bash shell by typing bash:

You can run Bash script like bash ./script.sh, but keep in mind that C drive is located at /mnt/c, and external hard drives are not mountable. So you might need to change your script a bit so it is compatible to Windows.

Also, even as root, you can still get permission denied when moving files around in /mnt, but you have your full root power in the / file system.

Also make sure your shell script is formatted with Unix style, or there can be errors.

$(this).dialog('destroy').remove()

This will destroy the dialog and then remove the div that was "hosting" the dialog completely from the DOM

You can set the line height on the text, for example within the active class:

.active {
    ...
    line-height: 2em;
    ....
}

To complete the other answers: If you are using C++11, use nullptr, which is a keyword that means a void pointer pointing to null. (instead of NULL, which is not a pointer type)

I can see that you have received many correct answers and very detailed one. I believe you are not testing it for very large prime numbers. And your only concern is to avoid printing intermediary prime number by your program.

A tiny change your program will do the trick.

Keep your logic same way and just pull out the print statement outside of loop. Break outer loop after n prime numbers.

import java.util.Scanner;
/**
 * Calculates the nth prime number
 * @author {Zyst}
 */
public class Prime {
    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);
        int n, 
            i = 2, 
            x = 2;

        System.out.printf("This program calculates the nth Prime number\n");
        System.out.printf("Please enter the nth prime number you want to find:");
        n = input.nextInt();

        for(i = 2, x = 2; n > 0; i++) {
            for(x = 2; x < i; x++) {
                if(i % x == 0) {
                    break;
                }
            }
            if(x == i) {
                n--;
            }
        }
        System.out.printf("\n%d is prime", x);

    }
}

Am going to try and add value to this very good question and to build on @BrittonKerin's question in one of the comments under @David Wolever's fantastic answer. Wanted to share here because I had the same challenge as @BrittonKerin and I got something working (i.e. just want to run a piece of code only IF the table doesn't exist).

        # for completeness lets do the routine thing of connections and cursors
        conn = sqlite3.connect(db_file, timeout=1000) 

        cursor = conn.cursor() 

        # get the count of tables with the name  
        tablename = 'KABOOM' 
        cursor.execute("SELECT count(name) FROM sqlite_master WHERE type='table' AND name=? ", (tablename, ))

        print(cursor.fetchone()) # this SHOULD BE in a tuple containing count(name) integer.

        # check if the db has existing table named KABOOM
        # if the count is 1, then table exists 
        if cursor.fetchone()[0] ==1 : 
            print('Table exists. I can do my custom stuff here now.... ')
            pass
        else: 
           # then table doesn't exist. 
           custRET = myCustFunc(foo,bar) # replace this with your custom logic

By default git revert refuses to revert a merge commit as what that actually means is ambiguous. I presume that your HEAD is in fact a merge commit.

If you want to revert the merge commit, you have to specify which parent of the merge you want to consider to be the main trunk, i.e. what you want to revert to.

Often this will be parent number one, for example if you were on master and did git merge unwanted and then decided to revert the merge of unwanted. The first parent would be your pre-merge master branch and the second parent would be the tip of unwanted.

In this case you could do:

git revert -m 1 HEAD

To get the row numbers where at least one item is larger than 15:

>>> np.where(np.any(e>15, axis=1))
(array([1, 2], dtype=int64),)

It's not only a Python bug with * actually, it can also happen when you pass a string as a part of your regular expression to be compiled, like ;

import re
input_line = "string from any input source"
processed_line= "text to be edited with {}".format(input_line)
target = "text to be searched"
re.search(processed_line, target)

this will cause an error if processed line contained some "(+)" for example, like you can find in chemical formulae, or such chains of characters. the solution is to escape but when you do it on the fly, it can happen that you fail to do it properly...

After further investigating on PSExec tool, I think I got the answer. I need to add -i option to tell PSExec to launch process on remote in interactive mode:

PSExec \\RPC001 -i -u myID -p myPWD PowerShell C:\script\StartPS.ps1 par1 par2

Without -i, powershell.exe is running on the remote in waiting mode. Interesting point is that if I run a simple bat (without PS in bat), it works fine. Maybe this is something special for PS case? Welcome comments and explanations.

In windows, if the above suggestion gives you an error (file not found or unknown db) you may want to double the forward slashes:

In the mysql console:

mysql> use DATABASE_NAME;

mysql> source C://path//to//file.sql;

util.pump is deprecated in node 0.10 and generates warning message

 util.pump() is deprecated. Use readableStream.pipe() instead

So the solution for copying files using streams is:

var source = fs.createReadStream('/path/to/source');
var dest = fs.createWriteStream('/path/to/dest');

source.pipe(dest);
source.on('end', function() { /* copied */ });
source.on('error', function(err) { /* error */ });

You can activate the proper header in PHP with this:

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, X-Requested-With");

One can also follow the below steps : Spyder -> Tools -> Open Command Prompt -> write the command "pip install html5lib"

Add this to your .pro file

QMAKE_CXXFLAGS += -std=c++11

or

CONFIG += c++11

Maybe.

Temporary tables prefixed with one # (#example) are kept on a per session basis. So if your code calls the stored procedure again while another call is running (for example background threads) then the create call will fail because it's already there.

If you're really worried use a table variable instead

DECLARE @MyTempTable TABLE 
(
   someField int,
   someFieldMore nvarchar(50)
)

This will be specific to the "instance" of that stored procedure call.

date = datetime.datetime(2003,8,1,12,4,5)
for i in range(5): 
    date += datetime.timedelta(days=1)
    print(date) 

There isn't really a formal manual, because there's no single style or standard.

So long as you understand the rules of identifier naming you can use whatever you like.

In practice, I find it easier to use lower_case_underscore_separated_identifiers because it isn't necessary to "Double Quote" them everywhere to preserve case, spaces, etc.

If you wanted to name your tables and functions "@MyA??! ""betty"" Shard$42" you'd be free to do that, though it'd be pain to type everywhere.

The main things to understand are:

• Unless double-quoted, identifiers are case-folded to lower-case, so MyTable, MYTABLE and mytable are all the same thing, but "MYTABLE" and "MyTable" are different;

• Unless double-quoted:

  SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

• You must double-quote keywords if you wish to use them as identifiers.

In practice I strongly recommend that you do not use keywords as identifiers. At least avoid reserved words. Just because you can name a table "with" doesn't mean you should.
