You can parse the JSON, then output it again with indents like this:

import json
mydata = json.loads(output)
print json.dumps(mydata, indent=4)

See http://docs.python.org/library/json.html for more info.

Open the project you want to add it.

Right click on the name. Then select, add in the active project. Then the cpp file will get its link to cbp.

If you have other testing applications like SQL web batch etc, uninstall them because they are running in port 3306.

Use the first:

std::sort(numbers.begin(), numbers.end(), std::greater<int>());

It's explicit of what's going on - less chance of misreading rbegin as begin, even with a comment. It's clear and readable which is exactly what you want.

Also, the second one may be less efficient than the first given the nature of reverse iterators, although you would have to profile it to be sure.

If you want to do it the way you showed in your question, this is a way to do it inline

class YourClass: UIViewController{

  @IBOutlet weak var tableView: UITableView!
  //other IBOutlets

  //THIS is how you declare a UIImageView inline
  let placeholderImage : UIImageView = {
        let placeholderImage = UIImageView(image: UIImage(named: "nophoto"))
        placeholderImage.contentMode = .scaleAspectFill
        return placeholderImage
    }()

   var someVariable: String!
   var someOtherVariable: Int!

   func someMethod(){
      //method code
   }

   //and so on
}

Basically both ArrayList and Vector both uses internal Object Array.

ArrayList: The ArrayList class extends AbstractList and implements the List interface and RandomAccess (marker interface). ArrayList supports dynamic arrays that can grow as needed. It gives us first iteration over elements. ArrayList uses internal Object Array; they are created with an default initial size of 10. When this size is exceeded, the collection is automatically increases to half of the default size that is 15.

Vector: Vector is similar to ArrayList but the differences are, it is synchronized and its default initial size is 10 and when the size exceeds its size increases to double of the original size that means the new size will be 20. Vector is the only class other than ArrayList to implement RandomAccess. Vector is having four constructors out of that one takes two parameters Vector(int initialCapacity, int capacityIncrement) capacityIncrement is the amount by which the capacity is increased when the vector overflows, so it have more control over the load factor.

Some other differences are:

For those of you using Visual Studio 2017 Professional, the registry key is:

HKCR\Licenses\5C505A59-E312-4B89-9508-E162F8150517

I also recommend you first export the registry key, before you delete it, so you'll have a backup if you accidentally delete the wrong key.

A good idea could be to encapsulate everything inside groups, no matter if need to identify them or not. That way you can use them in your replacement string. For example:

var pattern = @"(-)(\d+)(-)";
var replaced = Regex.Replace(text, pattern, "$1AA$3"); 

or using a MatchEvaluator:

var replaced = Regex.Replace(text, pattern, m => m.Groups[1].Value + "AA" + m.Groups[3].Value);

Another way, slightly messy, could be using a lookbehind/lookahead:

(?<=-)(\d+)(?=-)

You are indeed passing the first data item to the each function.

Pass data.programs to the each function instead. Change the code to as below:

<script>     
    $(document).ready(function() {         
        var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };         
        $.each(data.programs, function(key,val) {             
            alert(key+val);         
        });     
    }); 
</script> 

You can restart an existing container after it exited and your changes are still there.

docker start  `docker ps -q -l` # restart it in the background
docker attach `docker ps -q -l` # reattach the terminal & stdin

This was just happening to me, but none of the suggestions above worked. I changed directories ("cd ~/tmp") and suddenly the command

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

worked for me. Prior to changing directories I had been in a directory that is a Git repository. Perhaps that was interfering with the ruby and Git commands in the Brew install script.

Using requests with BeautifulSoup and Python 3:

import requests 
from bs4 import BeautifulSoup


page = requests.get('http://www.website.com')
bs = BeautifulSoup(page.content, features='lxml')
for link in bs.findAll('a'):
    print(link.get('href'))

I found a method using fseek and ftell and a thread with this question with answers that it can't be done in just C in another way.

You could use a portability library like NSPR (the library that powers Firefox).

Wrapping your components in a TouchableWithoutFeedback can cause some weird scroll behavior and other issues. I prefer to wrap my topmost app in a View with the onStartShouldSetResponder property filled in. This will allow me to handle all unhandled touches and then dismiss the keyboard. Importantly, since the handler function returns false the touch event is propagated up like normal.

 handleUnhandledTouches(){
   Keyboard.dismiss
   return false;
 }

 render(){
    <View style={{ flex: 1 }} onStartShouldSetResponder={this.handleUnhandledTouches}>
       <MyApp>
    </View>
  }

The file default.properties is by default read only, changing that worked for me.

You can actually modify your user settings and edit each colour individually by adding the following to the user settings.

1. Open user settings (ctrl + ,)
2. Search for workbench and select Edit in settings.json under Color Customizations

"workbench.colorCustomizations" : {
    "terminal.foreground" : "#00FD61",
    "terminal.background" : "#383737"
}

For more on what colors you can edit you can find out here.

Use serialize() on the variable, then save the string to a file. later you will be able to read the serialed var from the file and rebuilt the original var (wether it was a string or an array or an object)

@Chris You can use following lines of code to enable/disable dialog buttons until your check box check/unchecked

<div id="dialog-confirm" title="test">
    <label>Enable Confirm?<input type="checkbox" checked /></label>
</div>

    $("#dialog-confirm").dialog({
    resizable: false,
    height:240,
    modal: true,
    buttons: {
        Cancel: function() {
            $(this).dialog('close');
        },
        'Confirm': function() {
            $(this).dialog('close');
        }
    }
});

    $("#dialog-confirm :checkbox").change(function() {
        $(".ui-dialog-buttonpane button:contains('Confirm')")
           .button(this.checked ? "enable" : "disable");
    });

Old question, but just for posterity.

I've found the easiest way to do it is to have the image as the background image of the navbar-brand. Just makes sure to put in a custom width.

.navbar-brand
{
    margin-left: auto;
    margin-right: auto;
    width: 150px;
    background-image: url('logo.png');
}

I'll look at my docs; there's a way of specifying a configuration to change the path of the root web application away from ROOT (or ROOT.war), but it seems to have changed between Tomcat 5 and 6.

Found this:

http://www.nabble.com/Re:-Tomcat-6-and-ROOT-application...-td20017401.html

So, it seems that changing the root path (in ROOT.xml) is possible, but a bit broken -- you need to move your WAR outside of the auto-deployment directory. Mind if I ask why just renaming your file to ROOT.war isn't a workable solution?

adding a class touchscreen to the body using JS or jQuery

  //allowing mobile only css
    var isMobile = ('ontouchstart' in document.documentElement && navigator.userAgent.match(/Mobi/));
    if(isMobile){
        jQuery("body").attr("class",'touchscreen');
    }

If you use the relative version on http://www.foo.com/abc your browser will look at http://www.foo.com/abc/kitten.png for the image and would get 404 - Not found.

If using Anaconda, install with:

conda install PhantomJS

in your script:

from selenium import webdriver
driver=webdriver.PhantomJS()

works perfectly.

Something as this could be used

//Say given this array
$array_in_use2 = ['hay' => 'come', 'message' => 'no', 'story' => 'yes'];
//This gives either true or false if story and message is there
count(array_intersect(['story', 'message'], array_keys($array_in_use2))) === 2;

Note the check against 2, if the values you want to search is different you can change.

This solution may not be efficient, but it works!

Updates

In one fat function:

 /**
 * Like php array_key_exists, this instead search if (one or more) keys exists in the array
 * @param array $needles - keys to look for in the array
 * @param array $haystack - the <b>Associative</b> array to search
 * @param bool $all - [Optional] if false then checks if some keys are found
 * @return bool true if the needles are found else false. <br>
 * Note: if hastack is multidimentional only the first layer is checked<br>,
 * the needles should <b>not be<b> an associative array else it returns false<br>
 * The array to search must be associative array too else false may be returned
 */
function array_keys_exists($needles, $haystack, $all = true)
{
    $size = count($needles);
    if($all) return count(array_intersect($needles, array_keys($haystack))) === $size;
    return !empty(array_intersect($needles, array_keys($haystack)));

}

So for example with this:

$array_in_use2 = ['hay' => 'come', 'message' => 'no', 'story' => 'yes'];
//One of them exists --> true
$one_or_more_exists = array_keys_exists(['story', 'message'], $array_in_use2, false);
//all of them exists --> true
$all_exists = array_keys_exists(['story', 'message'], $array_in_use2);

Hope this helps :)

Use a Queue

Queue<String> qe=new LinkedList<String>();

qe.add("a");
qe.add("b");
qe.add("c");
qe.add("d");

System.out.println(qe.poll()); //returns a
System.out.println(qe.poll()); //returns b
System.out.println(qe.poll()); //returns c
System.out.println(qe.poll()); //returns d

There's five simple methods of a Queue

• element() -- Retrieves, but does not remove, the head of this queue.

• offer(E o) -- Inserts the specified element into this queue, if
  possible.

• peek() -- Retrieves, but does not remove, the head of this queue, returning null if this queue is empty.

• poll() -- Retrieves and removes the head of this queue, or null if this queue is empty.

• remove() -- Retrieves and removes the head of this queue.

ClientResponse response = webResource
                               .queryParams(queryParams) //
                               .header("Content-Type", "application/json") //
                               .header("id", "123") //
                               .get(ClientResponse.class) //
;

Just create a page-mytitle.php file to the folder of the current theme, and from the Dashboard a page "mytitle".

Then when you invoke the page by the URL you are going to see the page-mytitle.php. You must add HTML, CSS, JavaScript, wp-loop, etc. to this PHP file (page-mytitle.php).

To compare two lists with the order preserved use,

assertThat(actualList, contains("item1","item2"));

A stateless system can be seen as a box [black? ;)] where at any point in time the value of the output(s) depends only on the value of the input(s) [after a certain processing time]

A stateful system instead can be seen as a box where at any point in time the value of the output(s) depends on the value of the input(s) and of an internal state, so basicaly a stateful system is like a state machine with "memory" as the same set of input(s) value can generate different output(s) depending on the previous input(s) received by the system.

From the parallel programming point of view, a stateless system, if properly implemented, can be executed by multiple threads/tasks at the same time without any concurrency issue [as an example think of a reentrant function] A stateful system will requires that multiple threads of execution access and update the internal state of the system in an exclusive way, hence there will be a need for a serialization [synchronization] point.

another easy way and more flexible , after loading data into Datagrid

Private Sub Button_Export_Click(sender As Object, e As EventArgs) Handles Button_Export.Click
    Dim file As System.IO.StreamWriter
    file = My.Computer.FileSystem.OpenTextFileWriter("c:\1\Myfile.csv", True)
    If DataGridView1.Rows.Count = 0 Then GoTo loopend

    ' collect the header's names 
    Dim Headerline As String
    For k = 0 To DataGridView1.Columns.Count - 1
        If k = DataGridView1.Columns.Count - 1 Then ' last column dont put , separate 
            Headerline = Headerline & DataGridView1.Columns(k).HeaderText
        Else
            Headerline = Headerline & DataGridView1.Columns(k).HeaderText & ","
        End If
    Next
    file.WriteLine(Headerline)  ' this will write header names at the first line 
    ' collect the data 

    For i = 0 To DataGridView1.Rows.Count - 1
        Dim DataRow As String
        For k = 0 To DataGridView1.Columns.Count - 1
            If k = DataGridView1.Columns.Count - 1 Then
                DataRow = DataRow & DataGridView1.Rows(i).Cells(k).Value ' last column dont put , separate 
            End If
            DataRow = DataRow & DataGridView1.Rows(i).Cells(k).Value & ","
        Next

        file.WriteLine(DataRow)
        DataRow = ""
    Next



loopend:
        file.Close()
End Sub

A query's projection can only have one instance of a given name. As your WHERE clause shows, you have several tables with a column called ID. Because you are selecting * your projection will have several columns called ID. Or it would have were it not for the compiler hurling ORA-00918.

The solution is quite simple: you will have to expand the projection to explicitly select named columns. Then you can either leave out the duplicate columns, retaining just (say) COACHES.ID or use column aliases: coaches.id as COACHES_ID.

Perhaps that strikes you as a lot of typing, but it is the only way. If it is any comfort, SELECT * is regarded as bad practice in production code: explicitly named columns are much safer.

Another possible way is to delete the project from Eclipse (but don't delete the project contents from disk!) and then use the New Java Project wizard to create a project in-place. That wizard will detect the Java code and set up build paths automatically.

Here's the final code I [OP] used. Probably not best practice, but it worked.

function wrapText(context, text, x, y, maxWidth, lineHeight) {

    var breaks = text.split('\n');
    var newLines = "";
    for(var i = 0; i < breaks.length; i ++){
      newLines = newLines + breaks[i] + ' breakLine ';
    }

    var words = newLines.split(' ');
    var line = '';
    console.log(words);
    for(var n = 0; n < words.length; n++) {
      if(words[n] != 'breakLine'){
        var testLine = line + words[n] + ' ';
        var metrics = context.measureText(testLine);
        var testWidth = metrics.width;
        if (testWidth > maxWidth && n > 0) {
          context.fillText(line, x, y);
          line = words[n] + ' ';
          y += lineHeight;
        }
        else {
          line = testLine;
        }
      }else{
          context.fillText(line, x, y);
          line = '';
          y += lineHeight;
      }
    }
    context.fillText(line, x, y);
  }

public event EventHandler ImageFullPath1Changed;

public string ImageFullPath1
{
    get
    {
        // insert getter logic
    }
    set
    {
        // insert setter logic       

        // EDIT -- this example is not thread safe -- do not use in production code
        if (ImageFullPath1Changed != null && value != _backingField)
            ImageFullPath1Changed(this, new EventArgs(/*whatever*/);
    }
}                        

That said, I completely agree with Ryan. This scenario is precisely why INotifyPropertyChanged exists.

This is the best solution you'll found

var list3 = list1.Where(l => list2.ToList().Contains(l));

Bit counter-intuitive, but you must first setup a SDK for Java projects. On the bottom right of the IntelliJ welcome screen, select 'Configure > Project Defaults > Project Structure'.

The Project tab on the left will show that you have no SDK selected:

Therefore, you must click the 'New...' button on the right hand side of the dropdown and point it to your JDK. After that, you can go back to the import screen and it should be populated with your JAVA_HOME variable, providing you have this set.

Real, User and Sys process time statistics

One of these things is not like the other. Real refers to actual elapsed time; User and Sys refer to CPU time used only by the process.

• Real is wall clock time - time from start to finish of the call. This is all elapsed time including time slices used by other processes and time the process spends blocked (for example if it is waiting for I/O to complete).

• User is the amount of CPU time spent in user-mode code (outside the kernel) within the process. This is only actual CPU time used in executing the process. Other processes and time the process spends blocked do not count towards this figure.

• Sys is the amount of CPU time spent in the kernel within the process. This means executing CPU time spent in system calls within the kernel, as opposed to library code, which is still running in user-space. Like 'user', this is only CPU time used by the process. See below for a brief description of kernel mode (also known as 'supervisor' mode) and the system call mechanism.

User+Sys will tell you how much actual CPU time your process used. Note that this is across all CPUs, so if the process has multiple threads (and this process is running on a computer with more than one processor) it could potentially exceed the wall clock time reported by Real (which usually occurs). Note that in the output these figures include the User and Sys time of all child processes (and their descendants) as well when they could have been collected, e.g. by wait(2) or waitpid(2), although the underlying system calls return the statistics for the process and its children separately.

Origins of the statistics reported by time (1)

The statistics reported by time are gathered from various system calls. 'User' and 'Sys' come from wait (2) (POSIX) or times (2) (POSIX), depending on the particular system. 'Real' is calculated from a start and end time gathered from the gettimeofday (2) call. Depending on the version of the system, various other statistics such as the number of context switches may also be gathered by time.

On a multi-processor machine, a multi-threaded process or a process forking children could have an elapsed time smaller than the total CPU time - as different threads or processes may run in parallel. Also, the time statistics reported come from different origins, so times recorded for very short running tasks may be subject to rounding errors, as the example given by the original poster shows.

A brief primer on Kernel vs. User mode

On Unix, or any protected-memory operating system, 'Kernel' or 'Supervisor' mode refers to a privileged mode that the CPU can operate in. Certain privileged actions that could affect security or stability can only be done when the CPU is operating in this mode; these actions are not available to application code. An example of such an action might be manipulation of the MMU to gain access to the address space of another process. Normally, user-mode code cannot do this (with good reason), although it can request shared memory from the kernel, which could be read or written by more than one process. In this case, the shared memory is explicitly requested from the kernel through a secure mechanism and both processes have to explicitly attach to it in order to use it.

The privileged mode is usually referred to as 'kernel' mode because the kernel is executed by the CPU running in this mode. In order to switch to kernel mode you have to issue a specific instruction (often called a trap) that switches the CPU to running in kernel mode and runs code from a specific location held in a jump table. For security reasons, you cannot switch to kernel mode and execute arbitrary code - the traps are managed through a table of addresses that cannot be written to unless the CPU is running in supervisor mode. You trap with an explicit trap number and the address is looked up in the jump table; the kernel has a finite number of controlled entry points.

The 'system' calls in the C library (particularly those described in Section 2 of the man pages) have a user-mode component, which is what you actually call from your C program. Behind the scenes, they may issue one or more system calls to the kernel to do specific services such as I/O, but they still also have code running in user-mode. It is also quite possible to directly issue a trap to kernel mode from any user space code if desired, although you may need to write a snippet of assembly language to set up the registers correctly for the call.

More about 'sys'

There are things that your code cannot do from user mode - things like allocating memory or accessing hardware (HDD, network, etc.). These are under the supervision of the kernel, and it alone can do them. Some operations like malloc orfread/fwrite will invoke these kernel functions and that then will count as 'sys' time. Unfortunately it's not as simple as "every call to malloc will be counted in 'sys' time". The call to malloc will do some processing of its own (still counted in 'user' time) and then somewhere along the way it may call the function in kernel (counted in 'sys' time). After returning from the kernel call, there will be some more time in 'user' and then malloc will return to your code. As for when the switch happens, and how much of it is spent in kernel mode... you cannot say. It depends on the implementation of the library. Also, other seemingly innocent functions might also use malloc and the like in the background, which will again have some time in 'sys' then.

Wikipedia has the following information about USING:

The USING construct is more than mere syntactic sugar, however, since the result set differs from the result set of the version with the explicit predicate. Specifically, any columns mentioned in the USING list will appear only once, with an unqualified name, rather than once for each table in the join. In the case above, there will be a single DepartmentID column and no employee.DepartmentID or department.DepartmentID.

Tables that it was talking about:

The Postgres documentation also defines them pretty well:

The ON clause is the most general kind of join condition: it takes a Boolean value expression of the same kind as is used in a WHERE clause. A pair of rows from T1 and T2 match if the ON expression evaluates to true.

The USING clause is a shorthand that allows you to take advantage of the specific situation where both sides of the join use the same name for the joining column(s). It takes a comma-separated list of the shared column names and forms a join condition that includes an equality comparison for each one. For example, joining T1 and T2 with USING (a, b) produces the join condition ON T1.a = T2.a AND T1.b = T2.b.

Furthermore, the output of JOIN USING suppresses redundant columns: there is no need to print both of the matched columns, since they must have equal values. While JOIN ON produces all columns from T1 followed by all columns from T2, JOIN USING produces one output column for each of the listed column pairs (in the listed order), followed by any remaining columns from T1, followed by any remaining columns from T2.

Use the StringUtils class, it also includes null check

StringUtils.leftPad(String str, int size)
StringUtils.rightPad(String str, int size)

Two things are happening here, and it's important to understand both.

As described in other answers, the Symbol#to_proc method is being called.

But the reason to_proc is being called on the symbol is because it's being passed to map as a block argument. Placing & in front of an argument in a method call causes it to be passed this way. This is true for any Ruby method, not just map with symbols.

def some_method(*args, &block)
  puts "args: #{args.inspect}"
  puts "block: #{block.inspect}"
end

some_method(:whatever)
# args: [:whatever]
# block: nil

some_method(&:whatever)
# args: []
# block: #<Proc:0x007fd23d010da8>

some_method(&"whatever")
# TypeError: wrong argument type String (expected Proc)
# (String doesn't respond to #to_proc)

The Symbol gets converted to a Proc because it's passed in as a block. We can show this by trying to pass a proc to .map without the ampersand:

arr = %w(apple banana)
reverse_upcase = proc { |i| i.reverse.upcase }
reverse_upcase.is_a?(Proc)
=> true

arr.map(reverse_upcase)
# ArgumentError: wrong number of arguments (1 for 0)
# (map expects 0 positional arguments and one block argument)

arr.map(&reverse_upcase)
=> ["ELPPA", "ANANAB"]

Even though it doesn't need to be converted, the method won't know how to use it because it expects a block argument. Passing it with & gives .map the block it expects.

If you need to be checking external pages, you won't be able to get away with a pure javascript solution, since any requests to external URLs are blocked. You can get away with it by using JSONP, but that won't work unless the page you're requesting only serves up JSON.

You need to have a proxy on your own server to get the external links for you. This is actually rather simple with any server-side language.

<?php
$contents = file_get_contents($_GET['url']); // please do some sanitation here...
                                             // i'm just showing an example.
echo $contents;
?>

If you needed to check server response codes (eg: 404, 301, etc), then using a library such as cURL in your server-side script could retrieve that information and then pass it onto your javascript app.

Thinking about it now, there probably could be JSONP-enabled proxies out there for you to use, should the "setting up my own proxy" option not be viable.

To run your application in PowerShell (since && is disallowed):

($env:NODE_ENV="production") -and (node myapp/app.js)

Note that the text output of what the server's doing is suppressed, and I am not sure if that's fixable. (Expanding on @jsalonen's answer.)

Simpler way would be

$mystring = json_encode($my_json,JSON_UNESCAPED_SLASHES);

My numeric control:

function CheckNumeric(event) {
    var _key = (window.Event) ? event.which : event.keyCode;
    if (_key > 95 && _key < 106) {
        return true;
    }
    else if (_key > 47 && _key < 58) {
        return true;
    }
    else {
        return false;
    }
}

<input type="text" onkeydown="return CheckNumerick(event);" />

try it

BackSpace key code is 8

1. Use Concat or Union extension methods. You have to make sure that you have this direction using System.Linq; in order to use LINQ extensions methods.

2. Use the AddRange method.

The right way to do it in SDK V2, without the overload of actually getting the object, is to use S3Client.headObject. Officially backed by AWS Change Log.

Example code:

public boolean exists(String bucket, String key) {
    try {
        HeadObjectResponse headResponse = client
                .headObject(HeadObjectRequest.builder().bucket(bucket).key(key).build());
        return true;
    } catch (NoSuchKeyException e) {
        return false;
    }
}

The easiest way is through css3 $("select option:selected") and then use the .text() or .html() function. depending on what you want to have.

I needed this same solution, but if you use the native ListObject.Add() method then you avoid the risk of clashing with any data immediately below the table. The below routine checks the last row of the table, and adds the data in there if it's blank; otherwise it adds a new row to the end of the table:

Sub AddDataRow(tableName As String, values() As Variant)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = ActiveWorkbook.Worksheets("Sheet1")
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        For col = 1 To lastRow.Columns.Count
            If Trim(CStr(lastRow.Cells(1, col).Value)) <> "" Then
                table.ListRows.Add
                Exit For
            End If
        Next col
    Else
        table.ListRows.Add
    End If

    'Iterate through the last row and populate it with the entries from values()
    Set lastRow = table.ListRows(table.ListRows.Count).Range
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(values) + 1 Then lastRow.Cells(1, col) = values(col - 1)
    Next col
End Sub

To call the function, pass the name of the table and an array of values, one value per column. You can get / set the name of the table from the Design tab of the ribbon, in Excel 2013 at least:

Example code for a table with three columns:

Dim x(2)
x(0) = 1
x(1) = "apple"
x(2) = 2
AddDataRow "Table1", x

MSalters solution is a good one but basically re-implements boost::assign::map_list_of. If you have boost, you can use it directly:

#include <boost/assign/list_of.hpp>
#include <boost/unordered_map.hpp>
#include <iostream>

using boost::assign::map_list_of;

enum eee { AA,BB,CC };

const boost::unordered_map<eee,const char*> eeeToString = map_list_of
    (AA, "AA")
    (BB, "BB")
    (CC, "CC");

int main()
{
    std::cout << " enum AA = " << eeeToString.at(AA) << std::endl;
    return 0;
}

Swift 3.0

Create a ViewController with the UITableViewDelegate and UITableViewDataSource protocols. Then create a tableView inside it, declaring its style to be UITableViewStyle.grouped. This will fix the headers.

lazy var tableView: UITableView = {
    let view = UITableView(frame: UIScreen.main.bounds, style: UITableViewStyle.grouped)
    view.delegate = self
    view.dataSource = self
    view.separatorStyle = .none
    return view
}()

Found this elsewhere on the web, it deletes basically everything (except the workspace.xml file, which you can delete manually from the project folder).

1. Right Click on the project name under the save icon.
2. Click delete
3. Go to your project folder and check all the files were deleted.

Easy!

Just split the incoming address list on the ";" character, and add them to the mail message:

foreach (var address in addresses.Split(new [] {";"}, StringSplitOptions.RemoveEmptyEntries))
{
    mailMessage.To.Add(address);    
}

In this example, addresses contains "[email protected];[email protected]".

Your code sample didn't expand on part of your topic, namely symbols, and so that part of the question went unanswered.

If you have two strings, foo and bar, and both can be either a string or a symbol, you can test equality with

foo.to_s == bar.to_s

It's a little more efficient to skip the string conversions on operands with known type. So if foo is always a string

foo == bar.to_s

But the efficiency gain is almost certainly not worth demanding any extra work on behalf of the caller.

Prior to Ruby 2.2, avoid interning uncontrolled input strings for the purpose of comparison (with strings or symbols), because symbols are not garbage collected, and so you can open yourself to denial of service through resource exhaustion. Limit your use of symbols to values you control, i.e. literals in your code, and trusted configuration properties.

Ruby 2.2 introduced garbage collection of symbols.

The second way is a tad more efficient, but a much better way is to execute them in batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
        }

        statement.executeBatch();
    }
}

You're however dependent on the JDBC driver implementation how many batches you could execute at once. You may for example want to execute them every 1000 batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

As to the multithreaded environments, you don't need to worry about this if you acquire and close the connection and the statement in the shortest possible scope inside the same method block according the normal JDBC idiom using try-with-resources statement as shown in above snippets.

If those batches are transactional, then you'd like to turn off autocommit of the connection and only commit the transaction when all batches are finished. Otherwise it may result in a dirty database when the first bunch of batches succeeded and the later not.

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (Connection connection = dataSource.getConnection()) {
        connection.setAutoCommit(false);

        try (PreparedStatement statement = connection.prepareStatement(SQL)) {
            // ...

            try {
                connection.commit();
            } catch (SQLException e) {
                connection.rollback();
                throw e;
            }
        }
    }
}

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

At first check the file address, it must be beside your .java file or in any address that you define in classpath environment variable. When you check this then try below.

1. you must use a file name by it's extension in File object constructor, as an example:

   File myFile = new File("test.txt");

2. but there is a better way to use it inside Scanner object by pass the filename absolute address, as an example:

   Scanner sc = new Scanner(Paths.get("test.txt"));

in this way you must import java.nio.file.Paths as well.

For Swift 4

tableView.reloadSections([0], with: UITableView.RowAnimation.fade)

If your apache tomcat asking for password,then just follow these steps: go to the home directory of apache then go to webapps folder open the META-INF inside that you will find an xml file named context.xml--open it in edit mode

and REMOVE THE COMMENT FROM the VALVE tag.

After that you dont need any user name and password.

I have a sample

import * as types from '../../helpers/ActionTypes';

var initialState = {
  changedValues: {}
};
const quickEdit = (state = initialState, action) => {

  switch (action.type) {

    case types.PRODUCT_QUICKEDIT:
      {
        const item = action.item;
        const changedValues = {
          ...state.changedValues,
          [item.id]: item,
        };

        return {
          ...state,
          loading: true,
          changedValues: changedValues,
        };
      }
    default:
      {
        return state;
      }
  }
};

export default quickEdit;

This is impossible as you cannot return from an asynchronous call inside a synchronous method.

In this case you need to pass a callback to foo that will receive the return value

function foo(address, fn){
  geocoder.geocode( { 'address': address}, function(results, status) {
     fn(results[0].geometry.location); 
  });
}

foo("address", function(location){
  alert(location); // this is where you get the return value
});

The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.

If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.

I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.

set codedirectory=C:\Users\code
for /r  %codedirectory% %%i in (*.c) do

Cakephp 3.5:

echo $this->Url->build($this->getRequest()->getRequestTarget());

Calling $this->request->here() is deprecated since 3.4, and will be removed in 4.0.0. You should use getRequestTarget() instead. $this->request is also deprecated, $this->getRequest() should be used.

Consider the following ComplexType AuthorType used by author element

<xsd:complexType name="AuthorType">
  <!-- compositor goes here -->
  <xsd:sequence>
     <xsd:element name="name" type="xsd:string"/>
     <xsd:element name="phone" type="tns:Phone"/>
  </xsd:sequence>
  <xsd:attribute name="id" type="tns:AuthorId"/>
</xsd:complexType>
<xsd:element name="author" type="tns:AuthorType"/>

If elementFormDefault="unqualified"

then following XML Instance is valid

<x:author xmlns:x="http://example.org/publishing">
   <name>Aaron Skonnard</name>
   <phone>(801)390-4552</phone>
</x:author>

the authors's name attribute is allowed without specifying the namespace(unqualified). Any elements which are a part of <xsd:complexType> are considered as local to complexType.

if elementFormDefault="qualified"

then the instance should have the local elements qualified

<x:author xmlns:x="http://example.org/publishing">
   <x:name>Aaron Skonnard</name>
   <x:phone>(801)390-4552</phone>
</x:author>

In the hopes of providing additional information for those who don't pick this up as quickly as others, I'd like to provide my scenario as it has a slightly different setup. My project was setup with the following directory structure (using Eclipse):

Project/
  src/                // application source code
    org/
      myproject/
        MyClass.java
  test/               // unit tests
  res/                // resources
    images/           // PNG images for icons
      my-image.png
    xml/              // XSD files for validating XML files with JAXB
      my-schema.xsd
    conf/             // default .conf file for Log4j
      log4j.conf
  lib/                // libraries added to build-path via project settings

I was having issues loading my resources from the res directory. I wanted all my resources separate from my source code (simply for managment/organization purposes). So, what I had to do was add the res directory to the build-path and then access the resource via:

static final ClassLoader loader = MyClass.class.getClassLoader();

// in some function
loader.getResource("images/my-image.png");
loader.getResource("xml/my-schema.xsd");
loader.getResource("conf/log4j.conf");

NOTE: The / is omitted from the beginning of the resource string because I am using ClassLoader.getResource(String) instead of Class.getResource(String).

My vote would be to name it IsLast and change the functionality. If that isn't really an option, I'd leave the name as IsNotLast.

I agree with Code Complete (Use positive boolean variable names), I also believe that rules are made to be broken. The key is to break them only when you absoluately have to. In this case, none of the alternative names are as clear as the name that "breaks" the rule. So this is one of those times where breaking the rule can be okay.

C array:

NSInteger array[6] = {1, 2, 3, 4, 5, 6};

Objective-C Array:

NSArray *array = @[@1, @2, @3, @4, @5, @6];
// numeric values must in that case be wrapped into NSNumbers

Swift Array:

var array = [1, 2, 3, 4, 5, 6]

This is correct too:

var array = Array(1...10)

NB: arrays are strongly typed in Swift; in that case, the compiler infers from the content that the array is an array of integers. You could use this explicit-type syntax, too:

var array: [Int] = [1, 2, 3, 4, 5, 6]

If you wanted an array of Doubles, you would use :

var array = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0] // implicit type-inference

or:

var array: [Double] = [1, 2, 3, 4, 5, 6] // explicit type

If you want buffers to work like tabs, check out the tabline plugin.

That uses a single window, and adds a line on the top to simulate the tabs (just showing the list of buffers). This came out a long time ago when tabs were only supported in GVim but not in the command line vim. Since it is only operating with buffers, everything integrates well with the rest of vim.

In my case the problem occured when i forgot to add the =0 on one function in my pure virtual class. It was fixed when the =0 was added. The same as for Frank above.

class ISettings
{
public: 
    virtual ~ISettings() {};
    virtual void OKFunction() =0;
    virtual void ProblemFunction(); // missing =0   
};

class Settings : ISettings
{
    virtual ~Settings() {};
    void OKFunction();
    void ProblemFunction(); 
};

void Settings::OKFunction()
{
    //stuff
}

void Settings::ProblemFunction()
{
    //stuff
}

You've another instance of Tomcat already running. You can confirm this by going to http://localhost:8080 in your webbrowser and check if you get the Tomcat default home page or a Tomcat-specific 404 error page. Both are equally valid evidence that Tomcat runs fine; if it didn't, then you would have gotten a browser specific HTTP connection timeout error message.

You need to shutdown it. Go to /bin subfolder of the Tomcat installation folder and execute the shutdown.bat (Windows) or shutdown.sh (Unix) script.

for more help please chech this answer.

Josh David Miller is correct.

PCoelho, In case you're wondering what $compile does behind the scenes and how HTML output is generated from the directive, please take a look below

The $compile service compiles the fragment of HTML("< test text='n' >< / test >") that includes the directive("test" as an element) and produces a function. This function can then be executed with a scope to get the "HTML output from a directive".

var compileFunction = $compile("< test text='n' > < / test >");
var HtmlOutputFromDirective = compileFunction($scope);

One of the best examples of Hadoop-like MapReduce implementation.

Keep in mind though that they are limited to key-value based implementations of the MapReduce idea (so they are limiting in applicability).

You mean two classes? "Chain" the selectors (no spaces between them):

.class1.class2 {
    /* style here */
}

This selects all elements with class1 that also have class2.

In your case:

li.left.ui-class-selector {

}

I run into this a bit working with legacy stuff where they only work on east coast US and don't store dates in UTC, it's all EST. I have to filter on the dates based on user input in the browser so must pass the date in local time in JSON format.

Just to elaborate on this solution already posted - this is what I use:

// Could be picked by user in date picker - local JS date
date = new Date();

// Create new Date from milliseconds of user input date (date.getTime() returns milliseconds)
// Subtract milliseconds that will be offset by toJSON before calling it
new Date(date.getTime() - (date.getTimezoneOffset() * 60000)).toJSON();

So my understanding is this will go ahead and subtract time (in milliseconds (hence 60000) from the starting date based on the timezone offset (returns minutes) - in anticipation for the addition of time toJSON() is going to add.

If you are Windows guy and using "Tortoise SVN' user.

I nice one-liner, used JsonConvert as others have but added substring to remove the added quotes and backslash.

 var escapedJsonString = JsonConvert.ToString(JsonString).Substring(1, JsonString.Length - 2);

to work this with unicode or fontawesome, you should add a span with class like below, because input tag not support pseudo classes like :after. this is not a direct solution

in html:

   <span class="button1 search"></span>
<input name="username">

in css:

.button1 {
    background-color: #B9D5AD;
    border-radius: 0.2em 0 0 0.2em;
    box-shadow: 1px 0 0 rgba(0, 0, 0, 0.5), 2px 0 0 rgba(255, 255, 255, 0.5); 
    pointer-events: none;
    margin:1px 12px;    
    border-radius: 0.2em;    
    color: #333333;
    cursor: pointer;
    position: absolute;
    padding: 3px;
    text-decoration: none;   

}

You seem to be specifying the form to use a HTTP 'GET' request using FormMethod.Get. This will not work unless you tell it to do a post as that is what you seem to want the ActionResult to do. This will probably work by changing FormMethod.Get to FormMethod.Post.

As well as this you may also want to think about how Get and Post requests work and how these interact with the Model.

Pynput is the best solution I have found, both for Windows and for Mac. Super easy to program, and works very well.

For example,

from pynput.mouse import Button, Controller

mouse = Controller()

# Read pointer position
print('The current pointer position is {0}'.format(
    mouse.position))

# Set pointer position
mouse.position = (10, 20)
print('Now we have moved it to {0}'.format(
    mouse.position))

# Move pointer relative to current position
mouse.move(5, -5)

# Press and release
mouse.press(Button.left)
mouse.release(Button.left)

# Double click; this is different from pressing and releasing
# twice on Mac OSX
mouse.click(Button.left, 2)

# Scroll two steps down
mouse.scroll(0, 2)

You had a mistake on the statement below. Use . not ,

echo '<img src="', $dir, '/', $file, '" alt="', $file, $

to

echo '<img src="'. $dir. '/'. $file. '" alt="'. $file. $

and

echo 'Directory \'', $dir, '\' not found!';

to

echo 'Directory \''. $dir. '\' not found!';

I wrote a simple script that test the speed and this is what I found out. Actually for loop was fastest in my case. That really suprised me, check out bellow (was calculating sum of squares).

def square_sum1(numbers):
    return reduce(lambda sum, next: sum+next**2, numbers, 0)


def square_sum2(numbers):
    a = 0
    for i in numbers:
        i = i**2
        a += i
    return a

def square_sum3(numbers):
    sqrt = lambda x: x**2
    return sum(map(sqrt, numbers))

def square_sum4(numbers):

PCDATA - Parsed Character Data

XML parsers normally parse all the text in an XML document.

CDATA - (Unparsed) Character Data

The term CDATA is used about text data that should not be parsed by the XML parser.

Characters like "<" and "&" are illegal in XML elements.

You should try the HttpWebRequest class.

I have a huge database with no (separate) index.

Any time I query by the primary key the results are, for all intensive purposes, instant.

Got this error in Entity Framework 6 with this code at runtime:

var fileEventsSum = db.ImportInformations.Sum(x => x.FileEvents)

Update from LeandroSoares:

Use this for single execution:

var fileEventsSum = db.ImportInformations.Sum(x => (int?)x.FileEvents) ?? 0

Original:

Changed to this and then it worked:

var fileEventsSum = db.ImportInformations.Any() ? db.ImportInformations.Sum(x => x.FileEvents) : 0;

Try this:

<select>
    <option value="">&nbsp;
    <option>Option 1
    <option>Option 2
    <option>Option 3
</select>

Validates in HTML5. Works with required attribute in select element. Can be re-selected. Works in Google Chrome 45, Internet Explorer 11, Edge, Firefox 41.

Use time

Let's say you have the initial dates as strings like these:
date1 = "31/12/2015"
date2 = "01/01/2016"

You can do the following:
newdate1 = time.strptime(date1, "%d/%m/%Y") and newdate2 = time.strptime(date2, "%d/%m/%Y") to convert them to python's date format. Then, the comparison is obvious:

newdate1 > newdate2 will return False
newdate1 < newdate2 will return True

Even though they are separate windows but the request you send from Postman, it's details should be available in network tab of developer tools. Just make sure you are not sending any other http traffic during that time, just for clarity.

The right is php_memcache.dll. In my case i was using lib compiled with vc9 instead of vc6 compiler. In apatche error logs i got something like:

PHP Startup: sqlanywhere: Unable to initialize module Module compiled with build ID=API20090626, TS,VC9 PHP compiled with build ID=API20090626, TS,VC6 These options need to match

Check if you have same log and try downloading different dll that are compiled with different compiler.

The ODP.Net provider from oracle uses bind by position as default. To change the behavior to bind by name. Set property BindByName to true. Than you can dismiss the double definition of parameters.

    ...
}

I see that the autoload functions only receive the "full" classname - with all the namespaces preceeding it - in the following two cases:

[a] $a = new The\Full\Namespace\CoolClass();

[b] use The\Full\Namespace as SomeNamespace; (at the top of your source file) followed by $a = new SomeNamespace\CoolClass();

I see that the autoload functions DO NOT receive the full classname in the following case:

[c] use The\Full\Namespace; (at the top of your source file) followed by $a = new CoolClass();

UPDATE: [c] is a mistake and isn't how namespaces work anyway. I can report that, instead of [c], the following two cases also work well:

[d] use The\Full\Namespace; (at the top of your source file) followed by $a = new Namespace\CoolClass();

[e] use The\Full\Namespace\CoolClass; (at the top of your source file) followed by $a = new CoolClass();

Hope this helps.

Here's some info from my blog on how I like to use formular1c1 outside of vba:

You’ve just finished writing a formula, copied it to the whole spreadsheet, formatted everything and you realize that you forgot to make a reference absolute: every formula needed to reference Cell B2 but now, they all reference different cells.

How are you going to do a Find/Replace on the cells, considering that one has B5, the other C12, the third D25, etc., etc.?

The easy way is to update your Reference Style to R1C1. The R1C1 reference works with relative positioning: R marks the Row, C the Column and the numbers that follow R and C are either relative positions (between [ ]) or absolute positions (no [ ]).

Examples:

• R[2]C refers to the cell two rows below the cell in which the formula’s in
• RC[-1] refers to the cell one column to the left
• R1C1 refers the cell in the first row and first cell ($A$1)

What does it matter? Well, When you wrote your first formula back in the beginning of this post, B2 was the cell 4 rows above the cell you wrote it in, i.e. R[-4]C. When you copy it across and down, while the A1 reference changes, the R1C1 reference doesn’t. Throughout the whole spreadsheet, it’s R[-4]C. If you switch to R1C1 Reference Style, you can replace R[-4]C by R2C2 ($B$2) with a simple Find / Replace and be done in one fell swoop.

Running npm init -y makes your package.json with all the defaults.
You can then change package.json accordingly
This saves time many a times by preventing pressing enter on every command in npm init

Yes, should try reinstall mysql, but use the --reinstall flag to force a package reconfiguration. So the operating system service configuration is not skipped:

sudo apt --reinstall install mysql-server

To quickly find a meaningful error message by inspecting the error during debugging:

• Add a quick watch for:

  ((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors
  

• Drill down into EntityValidationErrors like this:

  (collection item e.g. [0]) > ValidationErrors > (collection item e.g. [0]) > ErrorMessage

Use the static Double.isNaN(double) method, or your Double's .isNaN() method.

// 1. static method
if (Double.isNaN(doubleValue)) {
    ...
}
// 2. object's method
if (doubleObject.isNaN()) {
    ...
}

Simply doing:

if (var == Double.NaN) {
    ...
}

is not sufficient due to how the IEEE standard for NaN and floating point numbers is defined.

As pointed out by in the comments, this answers is outdated. youcompleteme now supports python3 and jedi-vim no longer breaks the undo history.

Original answer below.

AFAIK there are three options, each with its disadvantages:

1. youcompleteme: unfriendly to install, but works nice if you manage to get it working. However python3 is not supported.
2. jedi-vim: coolest name, but breaks your undo history.
3. python-mode does a lot more the autocomplete: folding, syntax checking, highlighting. Personally I prefer scripts that do 1 thing well, as they are easier to manage (and replace). Differently from the two other options, it uses rope instead of jedi for autocompletion.

Python 3 and undo history (gundo!) are a must for me, so options 1 and 2 are out.

A CustomValidator would also work here:

<asp:CustomValidator runat="server"
    ID="valDateRange" 
    ControlToValidate="txtDatecompleted"
    onservervalidate="valDateRange_ServerValidate" 
    ErrorMessage="enter valid date" />

Code-behind:

protected void valDateRange_ServerValidate(object source, ServerValidateEventArgs args)
{
    DateTime minDate = DateTime.Parse("1000/12/28");
    DateTime maxDate = DateTime.Parse("9999/12/28");
    DateTime dt;

    args.IsValid = (DateTime.TryParse(args.Value, out dt) 
                    && dt <= maxDate 
                    && dt >= minDate);
}

If you are using Java, you could just replace the x00 characters before the insert like following:

myValue.replaceAll("\u0000", "")

The solution was provided and explained by Csaba in following post:

https://www.postgresql.org/message-id/1171970019.3101.328.camel%40coppola.muc.ecircle.de

Respectively:

in Java you can actually have a "0x0" character in your string, and that's valid unicode. So that's translated to the character 0x0 in UTF8, which in turn is not accepted because the server uses null terminated strings... so the only way is to make sure your strings don't contain the character '\u0000'.

The NEW values (or NEW_BUFFER as you have renamed them) are only available when INSERTING and UPDATING. For DELETING you would need to use OLD (OLD_BUFFER). So your trigger would become:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR DELETE OR UPDATE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

You may need to add logic inside the trigger to cater for code that updates field1 from 'HBP000' to something else.

I would just do:

 $('#submiteButtonID').click(function(e){
     e.preventDefault();
     //do your stuff.
     $('#formId').submit();
 });

Call preventDefault at first and use submit() function later, if you just need to submit the form

Try this:

$(document).ready( function () {
  $('#example').dataTable({
    "order": []
  });
});

this will solve your problem.

You have to use initiailzers:

class DerivedClass : public BaseClass
{
public:
  DerivedClass()
    : BaseClass(<insert arguments here>)
  {
  }
};

This is also how you construct members of your class that don't have constructors (or that you want to initialize). Any members not mentioned will be default initialized. For example:

class DerivedClass : public BaseClass
{
public:
  DerivedClass()
    : BaseClass(<insert arguments here>)
    , nc(<insert arguments here>)
    //di will be default initialized.
  {
  }

private:
  NeedsConstructor nc;
  CanBeDefaultInit di;
};

The order the members are specified in is irrelevant (though the constructors must come first), but the order that they will be constructed in is in declaration order. So nc will always be constructed before di.

I was very frustrated trying to achieve a fitty-like tight text wrapping so I ended up using a canvas-based method which I arrived at by unsuccessfully trying other methods. What I was aiming for looks like the attached which turns out to be surprisingly difficult (for me). Hopefully one day we will have a simple CSS-only way of doing this. Downsides of this approach is the text is treated more like an image, but for some use cases this is fine.

assylias and Head of Catering have already given your the reason why the error is occurring.

Now regarding what you are doing, from what I understand, you don't need to use Select at all

I guess you are doing this from VBA PowerPoint? If yes, then your code be rewritten as

Dim sourceXL As Object, sourceBook As Object
Dim sourceSheet As Object, sourceSheetSum As Object
Dim lRow As Long
Dim measName As Variant, partName As Variant
Dim filepath As String

filepath = CStr(FileDialog)

'~~> Establish an EXCEL application object
On Error Resume Next
Set sourceXL = GetObject(, "Excel.Application")

'~~> If not found then create new instance
If Err.Number <> 0 Then
    Set sourceXL = CreateObject("Excel.Application")
End If
Err.Clear
On Error GoTo 0

Set sourceBook = sourceXL.Workbooks.Open(filepath)
Set sourceSheet = sourceBook.Sheets("Measurements")
Set sourceSheetSum = sourceBook.Sheets("Analysis Summary")

lRow = sourceSheetSum.Range("C" & sourceSheetSum.Rows.Count).End(xlUp).Row
measName = sourceSheetSum.Range("C3:C" & lRow)

lRow = sourceSheetSum.Range("D" & sourceSheetSum.Rows.Count).End(xlUp).Row
partName = sourceSheetSum.Range("D3:D" & lRow)

Check out FPDF (with FPDI):

These will let you open an pdf and add content to it in PHP. I'm guessing you can also use their functionality to search through the existing content for the values you need.

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

I would first create a DataTable with the columns that you require, then populate it via Linq-to-XML.

You could use a Select query to create an object that represents each row, then use the standard approach for creating DataRows for each item ...

class Quest
{
    public string Answer1;
    public string Answer2;
    public string Answer3;
    public string Answer4;
}

public static void Main()
{
    var doc = XDocument.Load("filename.xml");

    var rows = doc.Descendants("QuestId").Select(el => new Quest
    {
        Answer1 = el.Element("Answer1").Value,
        Answer2 = el.Element("Answer2").Value,
        Answer3 = el.Element("Answer3").Value,
        Answer4 = el.Element("Answer4").Value,
    });

    // iterate over the rows and add to DataTable ...

}

You're only getting the first line from the diamond operator <FILE> because you're evaluating it in scalar context:

$document = <FILE>; 

In list/array context, the diamond operator will return all the lines of the file.

@lines = <FILE>;
print @lines;

You have to invoke this class on the top of your page or class :

using System.Configuration;

Then you can use this Method that returns the connection string to be ready to passed to the sqlconnection object to continue your work as follows:

    private string ReturnConnectionString()
    {
       // Put the name the Sqlconnection from WebConfig..
        return ConfigurationManager.ConnectionStrings["DBWebConfigString"].ConnectionString;
    }

Just to make a clear clarification this is the value in the web Config:

  <add name="DBWebConfigString" connectionString="....." />   </connectionStrings>

In my case, the reason the buttons got pushed up was because the view above them was a ScrollView, and it got collapsed with the buttons pushed up above the keyboard no matter what value of android:windowSoftInputMode I was setting.

I was able to avoid my bottom row of buttons getting pushed up by the soft keyboard by setting

android:isScrollContainer="false" 

on the ScrollView that sits above the buttons.

Even better with jQuery:

jQuery('ul.nav li.dropdown').hover(function() {
  jQuery(this).find('.dropdown-menu').stop(true, true).show();
  jQuery(this).addClass('open');
}, function() {
  jQuery(this).find('.dropdown-menu').stop(true, true).hide();
  jQuery(this).removeClass('open');
});

It needs both jni.h and jni_md.h files, Try this

gcc -I/usr/lib/jvm/jdk1.7.0_07/include \
  -I/usr/lib/jvm/jdk1.7.0_07/include/linux filename.c

This will include both the broad JNI files and the ones necessary for linux

I have solve this issue by using default password "changeit".

One more way is to extend the application (as my application was to inherit and customize the parent). It invokes the parent and its commandlinerunner automatically.

@SpringBootApplication
public class ChildApplication extends ParentApplication{
    public static void main(String[] args) {
        SpringApplication.run(ChildApplication.class, args);
    }
}

If you're using transitioningDelegate (not the case in this question's example), also set modalPresentationStyle to .Custom.

Swift

let vc = storyboard.instantiateViewControllerWithIdentifier("...")
vc.transitioningDelegate = self
vc.modalPresentationStyle = .Custom

The problem you were facing might be because: you were having Office 32 bit and Command Prompt 64 bit. To solve the problem you need to follow 2 steps:

1. Open ODBC Manager for DSN using: C:\Windows\SysWOW64\odbcad32.exe This will open the ODBC Data Administrator for 32 bit version and you will see all the database drivers.

2. After this you need to open the 32 bit command prompt using: C:\Windows\SysWOW64\cmd.exe This will open the 32 bit version of command prompt. In this new CMD please recompile your Java program and run your program.

Hope this will help.

I also had the same problem. And I find the solution:

CTRL+ALT+G

Update:

Thanks to @Joost, install Atom package python-tools to make it work

Here's one way to do it—there are many others:

bool b[4];
int v = 7;  // number to dissect

for (int j = 0;  j < 4;  ++j)
   b [j] =  0 != (v & (1 << j));

It is hard to understand why use of a loop is not desired, but it is easy enough to unroll the loop:

bool b[4];
int v = 7;  // number to dissect

b [0] =  0 != (v & (1 << 0));
b [1] =  0 != (v & (1 << 1));
b [2] =  0 != (v & (1 << 2));
b [3] =  0 != (v & (1 << 3));

Or evaluating constant expressions in the last four statements:

b [0] =  0 != (v & 1);
b [1] =  0 != (v & 2);
b [2] =  0 != (v & 4);
b [3] =  0 != (v & 8);

To build on Louis's helpful answer...

Setting the User Agent in PhantomJS

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
...
caps = DesiredCapabilities.PHANTOMJS
caps["phantomjs.page.settings.userAgent"] = "whatever you want"
driver = webdriver.PhantomJS(desired_capabilities=caps)

The only minor issue is that, unlike for Firefox and Chrome, this does not return your custom setting:

driver.execute_script("return navigator.userAgent")

So, if anyone figures out how to do that in PhantomJS, please edit my answer or add a comment below! Cheers.

Try this:

 private void cleanlistbox(object sender, EventArgs e)
  {
     listBox1.DataSource = null;
     listBox1.Items.Clear();
  }

I also met this problem before. My situation was I didn't put all the 62 spring framework jars into the lib file (spring-framework-4.1.2.RELEASE edition), it did work. And then I also changed the 3.0.xsd into 2.5 or 3.1 for test, it all worked out. Of course, there are also other factors to affect your result.

The other answers don't mention that you can also set this in the XML of your Toolbar widget:

app:navigationIcon="?attr/homeAsUpIndicator"

For example:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:navigationIcon="?attr/homeAsUpIndicator"
    app:popupTheme="@style/AppTheme.PopupOverlay"
    app:title="@string/title_activity_acoustic_progress" />

If you want to consider null values equality too, try the following

select column1, column2, 
   case
      when column1 is NULL and column2 is NULL then 'true'  
      when column1=column2 then 'true' 
      else 'false' 
   end 
from table;

Here is what I use:

public static boolean onTablet()
    {
    int intScreenSize = getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK;

    return (intScreenSize == Configuration.SCREENLAYOUT_SIZE_LARGE) // LARGE
    || (intScreenSize == Configuration.SCREENLAYOUT_SIZE_LARGE + 1); // Configuration.SCREENLAYOUT_SIZE_XLARGE
    }

I just had the same issue and this helped me:

html {
    height: auto;
    min-height: 100%;
    background-size:cover;
}

When I was to get yesterday with just the date in the format Year/Month/Day I use:

$Variable = Get-Date((get-date ).AddDays(-1))  -Format "yyyy-MM-dd"

Yes, you can set the screen orientation programatically anytime you want using:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

for landscape and portrait mode respectively. The setRequestedOrientation() method is available for the Activity class, so it can be used inside your Activity.

And this is how you can get the current screen orientation and set it adequatly depending on its current state:

Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
final int orientation = display.getOrientation(); 
 // OR: orientation = getRequestedOrientation(); // inside an Activity

// set the screen orientation on button click
Button btn = (Button) findViewById(R.id.yourbutton);
btn.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {

              switch(orientation) {
                   case Configuration.ORIENTATION_PORTRAIT:
                       setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                       break;
                   case Configuration.ORIENTATION_LANDSCAPE:
                       setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                       break;                   
               }
          }
   });

Taken from here: http://techblogon.com/android-screen-orientation-change-rotation-example/

EDIT

Also, you can get the screen orientation using the Configuration:

Activity.getResources().getConfiguration().orientation

The difference between absolute and relative imports come into play only when you import a module from a package and that module imports an other submodule from that package. See the difference:

$ mkdir pkg
$ touch pkg/__init__.py
$ touch pkg/string.py
$ echo 'import string;print(string.ascii_uppercase)' > pkg/main1.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pkg/main1.py", line 1, in <module>
    import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
>>> 
$ echo 'from __future__ import absolute_import;import string;print(string.ascii_uppercase)' > pkg/main2.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 

In particular:

$ python2 pkg/main2.py
Traceback (most recent call last):
  File "pkg/main2.py", line 1, in <module>
    from __future__ import absolute_import;import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 
$ python2 -m pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ

Note that python2 pkg/main2.py has a different behaviour then launching python2 and then importing pkg.main2 (which is equivalent to using the -m switch).

If you ever want to run a submodule of a package always use the -m switch which prevents the interpreter for chaining the sys.path list and correctly handles the semantics of the submodule.

Also, I much prefer using explicit relative imports for package submodules since they provide more semantics and better error messages in case of failure.

I think a nice solution is with the function filter of pandas and regex (match everything except "b"):

df.filter(regex="^(?!b$)")

Try to do something like this:

db.getCollection('collectionName').find({'ArrayName.1': {$exists: true}})

1 is number, if you want to fetch record greater than 50 then do ArrayName.50 Thanks.

I use json_decode($response->getBody()) now instead of $response->json().

I suspect this might be a casualty of PSR-7 compliance.

I've got the same problem here. I have an UTF-8 Page an need to post to an ISO-8859-1 server.

Looks like IE can't handle ISO-8859-1. But it can handle ISO-8859-15.

<form accept-charset="ISO-8859-15">
  ...
</form>

So this worked for me, since ISO-8859-1 and ISO-8859-15 are almost the same.

Here is an example where pointer to data members could be useful:

#include <iostream>
#include <list>
#include <string>

template <typename Container, typename T, typename DataPtr>
typename Container::value_type searchByDataMember (const Container& container, const T& t, DataPtr ptr) {
    for (const typename Container::value_type& x : container) {
        if (x->*ptr == t)
            return x;
    }
    return typename Container::value_type{};
}

struct Object {
    int ID, value;
    std::string name;
    Object (int i, int v, const std::string& n) : ID(i), value(v), name(n) {}
};

std::list<Object*> objects { new Object(5,6,"Sam"), new Object(11,7,"Mark"), new Object(9,12,"Rob"),
    new Object(2,11,"Tom"), new Object(15,16,"John") };

int main() {
    const Object* object = searchByDataMember (objects, 11, &Object::value);
    std::cout << object->name << '\n';  // Tom
}

Your user settings are in ~/Library/Application\ Support/Code/User.

If you're not concerned about syncing and it's a one time thing, you can just copy the files keybindings.json and settings.json to the corresponding folder on your new machine.

Your extensions are in the ~/.vscode folder. Most extensions aren't using any native bindings and they should be working properly when copied over. You can manually re-install those who do not.

Assume we have a function sort(int *arraytobesorted,void (*algorithmchosen)(void)) where it can accept a function pointer as its argument which can be used at some point in sort()'s implementation . Then , here the code that is being addressed by the function pointer algorithmchosen is called as callback function .

And see the advantage is that we can choose any algorithm like:

  1.    algorithmchosen = bubblesort
  2.    algorithmchosen = heapsort
  3.    algorithmchosen = mergesort   ...

Which were, say,have been implemented with the prototype:

  1.   `void bubblesort(void)`
  2.   `void heapsort(void)`
  3.   `void mergesort(void)`   ...

This is a concept used in achieving Polymorphism in Object Oriented Programming

Surely you just need:

double seconds = milliseconds / 1000.0;

There's no need to manually do the two parts separately - you just need floating point arithmetic, which the use of 1000.0 (as a double literal) forces. (I'm assuming your milliseconds value is an integer of some form.)

Note that as usual with double, you may not be able to represent the result exactly. Consider using BigDecimal if you want to represent 100ms as 0.1 seconds exactly. (Given that it's a physical quantity, and the 100ms wouldn't be exact in the first place, a double is probably appropriate, but...)

var lat = homeMarker.getPosition().lat();
var lng = homeMarker.getPosition().lng();

See the google.maps.LatLng docs and google.maps.Marker getPosition().

This expands the ternary option into if/else which minified is equivalent to the ternary option but doesn't sacrifice readability.

const clamp = (value, min, max) => {
  if (value < min) return min;
  if (value > max) return max;
  return value;
}

Minifies to 35b (or 43b if using function):

const clamp=(c,a,l)=>c<a?a:c>l?l:c;

Also, depending on what perf tooling or browser you use you get various outcomes of whether the Math based implementation or ternary based implementation is faster. In the case of roughly the same performance, I would opt for readability.

In your regex you need to escape the dot "\." or use it inside a character class "[.]", as it is a meta-character in regex, which matches any character.

Also, you need \w+ instead of \w to match one or more word characters.

Now, if you want the test.this content, then split is not what you need. split will split your string around the test.this. For example:

>>> re.split(r"\b\w+\.\w+@", s)
['blah blah blah ', 'gmail.com blah blah']

You can use re.findall:

>>> re.findall(r'\w+[.]\w+(?=@)', s)   # look ahead
['test.this']
>>> re.findall(r'(\w+[.]\w+)@', s)     # capture group
['test.this']

Use:

 tabControl1.TabPages[1].Enabled = false;

By writing this code, the tab page won't be completely disabled (not being able to select), but its internal content will be disabled which I think satisfy your needs.

You can do this with a mix of Java and Scala libraries. You will have full control over the character encoding. But unfortunately, the file handles will not be closed properly.

scala> import java.io.ByteArrayInputStream
import java.io.ByteArrayInputStream

scala> import java.io.FileOutputStream

Adding value to all these answers,

many have asked the command for running App in AVD after build sucessful.

adb install -r {path-to-your-bild-folder}/{yourAppName}.apk

The select box arrow is a native ui element, it depends on the desktop theme or the web browser. Use a jQuery plugin (e.g. Select2, Chosen) or CSS.

Where clause and args work together to form the WHERE statement of the SQL query. So say you looking to express

WHERE Column1 = 'value1' AND Column2 = 'value2'

Then your whereClause and whereArgs will be as follows

String whereClause = "Column1 =? AND Column2 =?";
String[] whereArgs = new String[]{"value1", "value2"};

If you want to select all table columns, i believe a null string passed to tableColumns will suffice.

Use Render Script as mentioned here http://blog.neteril.org/blog/2013/08/12/blurring-images-on-android/

You can try this method that is developed by Chucai Yi and Yingli Tian.

They also share a software (which is based on Opencv-1.0 and it should run under Windows platform.) that you can use (though no source code available). It will generate all the text bounding boxes (shown in color shadows) in the image. By applying to your sample images, you will get the following results:

Note: to make the result more robust, you can further merge adjacent boxes together.

Update: If your ultimate goal is to recognize the texts in the image, you can further check out gttext, which is an OCR free software and Ground Truthing tool for Color Images with Text. Source code is also available.

With this, you can get recognized texts like:

overflow:hidden 

does not always mean that the element is hidden or non existent in the DOM, it means that the overflowing chars that do not fit in the element are being trimmed. Basically it means that do not show scrollbar even if it should be showed, so in your case the link with text

Plastic Spiral Bind

could possibly be shown as "Plastic Spir..." or similar. So it is possible, that this linkText indeed is non existent.

So you can probably try:

driver.findElement(By.partialLinkText("Plastic ")).click();

or xpath:

When I had to rasterize svgs on the server, I ended up using P/Invoke to call librsvg functions (you can get the dlls from a windows version of the GIMP image editing program).

[DllImport("kernel32.dll", SetLastError = true)]
static extern bool SetDllDirectory(string pathname);

[DllImport("libgobject-2.0-0.dll", SetLastError = true)]
static extern void g_type_init(); 

[DllImport("librsvg-2-2.dll", SetLastError = true)]
static extern IntPtr rsvg_pixbuf_from_file_at_size(string file_name, int width, int height, out IntPtr error);

[DllImport("libgdk_pixbuf-2.0-0.dll", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi)]
static extern bool gdk_pixbuf_save(IntPtr pixbuf, string filename, string type, out IntPtr error, __arglist);

public static void RasterizeSvg(string inputFileName, string outputFileName)
{
    bool callSuccessful = SetDllDirectory("C:\\Program Files\\GIMP-2.0\\bin");
    if (!callSuccessful)
    {
        throw new Exception("Could not set DLL directory");
    }
    g_type_init();
    IntPtr error;
    IntPtr result = rsvg_pixbuf_from_file_at_size(inputFileName, -1, -1, out error);
    if (error != IntPtr.Zero)
    {
        throw new Exception(Marshal.ReadInt32(error).ToString());
    }
    callSuccessful = gdk_pixbuf_save(result, outputFileName, "png", out error, __arglist(null));
    if (!callSuccessful)
    {
        throw new Exception(error.ToInt32().ToString());
    }
}

From a sqlite prompt:

sqlite> .read db.sql

Or:

cat db.sql | sqlite3 database.db

Also, your SQL is invalid - you need ; on the end of your statements:

create table server(name varchar(50),ipaddress varchar(15),id init);
create table client(name varchar(50),ipaddress varchar(15),id init);

If you want to split you dataframe into two different ones, do two selects on it with the different columns you want.

 val sourceDf = spark.read.csv(...)
 val df1 = sourceDF.select("first column", "second column", "third column")
 val df2 = sourceDF.select("first column", "second column", "third column")

Note that this of course means that the sourceDf would be evaluated twice, so if it can fit into distributed memory and you use most of the columns across both dataframes it might be a good idea to cache it. It it has many extra columns that you don't need, then you can do a select on it first to select on the columns you will need so it would store all that extra data in memory.

What worked for me is that i hadn't set the local_listener, to see if the local listener is set login to sqlplus / as sysdba, make sure the database is open and run the following command show parameter local_listener, if the value is empty, then you will have to set the local_listener with the following SQL command ALTER SYSTEM SET LOCAL_LISTENER='<LISTENER_NAME_GOES_HERE>'

this works, and can be adapted for weeks or anyother frequency i.e. weekly, quarterly etc...

=SUMIFS(B12:B11652,A12:A11652,">="&DATE(YEAR(C12),MONTH(C12),1),A12:A11652,"<"&DATE(YEAR(C12),MONTH(C12)+1,1))

SJF are two type - i) non preemptive SJF ii)pre-emptive SJF

I have re-arranged the processes according to Arrival time. here is the non preemptive SJF

A.T= Arrival Time

B.T= Burst Time

C.T= Completion Time

T.T = Turn around Time = C.T - A.T

W.T = Waiting Time = T.T - B.T

Here is the preemptive SJF Note: each process will preempt at time a new process arrives.Then it will compare the burst times and will allocate the process which have shortest burst time. But if two process have same burst time then the process which came first that will be allocated first just like FCFS.

getResourceAsStream is the right way to do it for web apps (as you already learned).

The reason is that reading from the file system cannot work if you package your web app in a WAR. This is the proper way to package a web app. It's portable that way, because you aren't dependent on an absolute file path or the location where your app server is installed.

You can specify a custom class to the top element of the dialog via the option dialogClass

$("#success").dialog({
    ...
    dialogClass:"myClass",
    ...
});

Then you can target this class in CSS via .myClass.ui-dialog.

For those of you landing here but searching how to break out of a loop that contains an include statement use return instead of break or continue.

<?php

for ($i=0; $i < 100; $i++) { 
    if (i%2 == 0) {
        include(do_this_for_even.php);
    }
    else {
        include(do_this_for_odd.php);
    }
}

?>

If you want to break when being inside do_this_for_even.php you need to use return. Using break or continue will return this error: Cannot break/continue 1 level. I found more details here

Another alternative with data.table.

EXAMPLE DATA

dt1 <- data.table(df1)
dt2 <- data.table(df2)
setkey(dt1,x)
setkey(dt2,x)

CODE

dt2[dt1,list(y=ifelse(is.na(y),0,y))]

There are many ways to print that.

Let's have a look with another example.

a = 10
b = 20
c = a + b

#Normal string concatenation
print("sum of", a , "and" , b , "is" , c) 

#convert variable into str
print("sum of " + str(a) + " and " + str(b) + " is " + str(c)) 

# if you want to print in tuple way
print("Sum of %s and %s is %s: " %(a,b,c))  

#New style string formatting
print("sum of {} and {} is {}".format(a,b,c)) 

#in case you want to use repr()
print("sum of " + repr(a) + " and " + repr(b) + " is " + repr(c))

EDIT :

#New f-string formatting from Python 3.6:
print(f'Sum of {a} and {b} is {c}')

Not 100% what you were looking for, but kind of an inside-out way of doing it:

I was looking for a way to play VMDK files without the vmx file in VMware Player 5 and didn't find any explicit tutorial to do it. So after some time messing around with VMware PLayer 5, it turned out to be pretty simple, but not so intuitive. Here it is:

Create a new virtual machine from VMware Player 5; There's no need to install an OS, since you already have the VMDK (Virtual Machine Disk); Set the Virtual Machine to the OS you'll be playing (the one from the VMDK); After creating the VM with the remaining creation wizard options, go to your VM settings; There you can remove the existing hard drive and add a new one; Upon addition of the new hard drive, point it to your existing VMDK file.

And that's it.

If you have problems starting the VM because VMware Player can't lock the VMDK file, rename/delete the dir/files with extension *.lck from the directory where the *.vmdk file is located.

Hope this is helpful.

This should do what you want:

preg_replace("/[^0-9]/", "",$c);

If expression returns a boolean, you can just return the result of it.

Example

 return (a > b)

This can be caused by a full disk (Ubuntu/Nginx).

My situation:

• this error occured in Chrome with Nginx serving a static file: ".../static/js/vendor.c4ed7962fb4a63ad3c3b.js net::ERR_CONTENT_LENGTH_MISMATCH 200 (OK)"
• root disk was full; after cleaning tmp files the error disappeared.
• to prevent: make sure your disk remains clean ( a script such as this could help:https://crunchify.com/how-to-automatically-delete-tmp-folders-in-linux-automatic-disk-log-cleanup-bash-script/ )

First check if the user has granted the permission:

if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
    == PackageManager.PERMISSION_DENIED)

Then, you could use this to request to the user:

ActivityCompat.requestPermissions(activity, new String[] {Manifest.permission.CAMERA}, requestCode);

And in Marshmallow, it will appear in a dialog

Add play-services-safetynet library in android build.gradle:

implementation 'com.google.android.gms:play-services-safetynet:+'

and add this code to your MainApplication.java:

@Override
  public void onCreate() {
    super.onCreate();
    upgradeSecurityProvider();
    SoLoader.init(this, /* native exopackage */ false);
  }

  private void upgradeSecurityProvider() {
    ProviderInstaller.installIfNeededAsync(this, new ProviderInstallListener() {
      @Override
      public void onProviderInstalled() {

      }

      @Override
      public void onProviderInstallFailed(int errorCode, Intent recoveryIntent) {
//        GooglePlayServicesUtil.showErrorNotification(errorCode, MainApplication.this);
        GoogleApiAvailability.getInstance().showErrorNotification(MainApplication.this, errorCode);
      }
    });
  }

A very general command prompt how to for java is

javac mainjava.java
java mainjava

You'll very often see people doing

javac *.java
java mainjava

As for the subclass problem that's probably occurring because a path is missing from your class path, the -c flag I believe is used to set that.

What's the column "BIO" datatype? What database server (sql/oracle/mysql)? You should be able to span over multiple lines all you want as long as you adhere to the character limit in the column's datatype (ie: varchar(200) ). Try using single quotes, that might make a difference. This works for me:

update table set mycolumn = 'hello world,
my name is carlos.
goodbye.'
where id = 1;

Also, you might want to put in checks for single quotes if you are concatinating the sql string together in C#. If the variable contains single quotes that could escape the code out of the sql statement, therefore, not doing all the lines you were expecting to see.

BTW, you can delimit your SQL statements with a semi colon like you do in C#, just as FYI.

To get the cheapest product in each category, you use the MIN() function in a correlated subquery as follows:

    SELECT categoryid,
       productid,
       productName,
       unitprice 
    FROM products a WHERE unitprice = (
                SELECT MIN(unitprice)
                FROM products b
                WHERE b.categoryid = a.categoryid)

The outer query scans all rows in the products table and returns the products that have unit prices match with the lowest price in each category returned by the correlated subquery.

Try

\d \w |\d

or add a positive lookahead if you don't want to include the trailing space in the match

\d \w(?= )|\d

When you have two alternatives where one is an extension of the other, put the longer one first, otherwise it will have no opportunity to be matched.

It sounds like what you want is a User who has many Questions.
The Question has many Answers, one of which is the User's Choice.

Is this what you are after?

I would model something like that along these lines:

class User
  has_many :questions
end

class Question
  belongs_to :user
  has_many   :answers
  has_one    :choice, :class_name => "Answer"

  validates_inclusion_of :choice, :in => lambda { answers }
end

class Answer
  belongs_to :question
end

First off, that's not JSON. It's a JavaScript object literal. JSON is a string representation of data, that just so happens to very closely resemble JavaScript syntax.

Second, you have an object. They are unsorted. The order of the elements cannot be guaranteed. If you want guaranteed order, you need to use an array. This will require you to change your data structure.

One option might be to make your data look like this:

var json = [{
    "name": "user1",
    "id": 3
}, {
    "name": "user2",
    "id": 6
}, {
    "name": "user3",
    "id": 1
}];

Now you have an array of objects, and we can sort it.

json.sort(function(a, b){
    return a.id - b.id;
});

The resulting array will look like:

[{
    "name": "user3",
    "id" : 1
}, {
    "name": "user1",
    "id" : 3
}, {
    "name": "user2",
    "id" : 6
}];

Only use:

sudo apt-get install php5-sqlite

and later

sudo service apache2 restart

While it may immediately seem useful to utilize class instance variables, since class instance variable are shared among subclasses and they can be referred to within both singleton and instance methods, there is a singificant drawback. They are shared and so subclasses can change the value of the class instance variable, and the base class will also be affected by the change, which is usually undesirable behavior:

class C
  @@c = 'c'
  def self.c_val
    @@c
  end
end

C.c_val
 => "c" 

class D < C
end

D.instance_eval do 
  def change_c_val
    @@c = 'd'
  end
end
 => :change_c_val 

D.change_c_val
(irb):12: warning: class variable access from toplevel
 => "d" 

C.c_val
 => "d" 

Rails introduces a handy method called class_attribute. As the name implies, it declares a class-level attribute whose value is inheritable by subclasses. The class_attribute value can be accessed in both singleton and instance methods, as is the case with the class instance variable. However, the huge benefit with class_attribute in Rails is subclasses can change their own value and it will not impact parent class.

class C
  class_attribute :c
  self.c = 'c'
end

 C.c
 => "c" 

class D < C
end

D.c = 'd'
 => "d" 

 C.c
 => "c" 

There can be another way which saves the day. Just init a new Dialog with desired layout and just show it. I need it for showing a loadingView over a DialogFragment and this was the only way I succeed.

Dialog topDialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);
topDialog.setContentView(R.layout.dialog_top);
topDialog.show();

bringToFront() might not work in some cases like mine. But content of dialog_top layout must override anything on the ui layer. But anyway, this is an ugly workaround.

I use moment to solve the problem. For example

var startDate = moment('2015-07-06 08:00', 'YYYY-MM-DD HH:mm').toDate();

i ran the local mysql database, but not in administrator mode, which threw this error

Those answers aren't bad, but they are limited in that they don't actually allow you to enter data. We had a similar problem where we were using barcode readers to enter data into a field, but we wanted to suppress the keyboard.

This is what I put together, it works pretty well:

https://codepen.io/bobjase/pen/QrQQvd/

<!-- must be a select box with no children to suppress the keyboard -->
input: <select id="hiddenField" /> 
<span id="fakecursor" />

<input type="text" readonly="readonly" id="visibleField" />
<div id="cursorMeasuringDiv" />

#hiddenField {
  height:17px; 
  width:1px;
  position:absolute;
  margin-left:3px;
  margin-top:2px;
  border:none;
  border-width:0px 0px 0px 1px;
}

#cursorMeasuringDiv {
  position:absolute;
  visibility:hidden;
  margin:0px;
  padding:0px;
}

#hiddenField:focus {
  border:1px solid gray;  
  border-width:0px 0px 0px 1px;
  outline:none;
  animation-name: cursor;
  animation-duration: 1s;
  animation-iteration-count: infinite;
}

@keyframes cursor {
    from {opacity:0;}
    to {opacity:1;}
}

// whenever the visible field gets focused
$("#visibleField").bind("focus", function(e) {
  // silently shift the focus to the hidden select box
  $("#hiddenField").focus();
  $("#cursorMeasuringDiv").css("font", $("#visibleField").css("font"));
});

// whenever the user types on his keyboard in the select box
// which is natively supported for jumping to an <option>
$("#hiddenField").bind("keypress",function(e) {
  // get the current value of the readonly field
  var currentValue = $("#visibleField").val();

  // and append the key the user pressed into that field
  $("#visibleField").val(currentValue + e.key);
  $("#cursorMeasuringDiv").text(currentValue + e.key);

  // measure the width of the cursor offset
  var offset = 3;
  var textWidth = $("#cursorMeasuringDiv").width();
  $("#hiddenField").css("marginLeft",Math.min(offset+textWidth,$("#visibleField").width()));

});

When you click in the <input> box, it simulates a cursor in that box but really puts the focus on an empty <select> box. Select boxes naturally allow for keypresses to support jumping to an element in the list so it was only a matter of rerouting the keypress to the original input and offsetting the simulated cursor.

This won't work for backspace, delete, etc... but we didn't need those. You could probably use jQuery's trigger to send the keyboard event directly to another input box somewhere but we didn't need to bother with that so I didn't do it.

Keep it simple.

I know maybe it is unnecessary, but I made a function which converts float to string:

CODE:

#include <stdio.h>

/** Number on countu **/

int n_tu(int number, int count)
{
    int result = 1;
    while(count-- > 0)
        result *= number;

    return result;
}

/*** Convert float to string ***/
void float_to_string(float f, char r[])
{
    long long int length, length2, i, number, position, sign;
    float number2;

    sign = -1;   // -1 == positive number
    if (f < 0)
    {
        sign = '-';
        f *= -1;
    }

    number2 = f;
    number = f;
    length = 0;  // Size of decimal part
    length2 = 0; // Size of tenth

    /* Calculate length2 tenth part */
    while( (number2 - (float)number) != 0.0 && !((number2 - (float)number) < 0.0) )
    {
         number2 = f * (n_tu(10.0, length2 + 1));
         number = number2;

         length2++;
    }

    /* Calculate length decimal part */
    for (length = (f > 1) ? 0 : 1; f > 1; length++)
        f /= 10;

    position = length;
    length = length + 1 + length2;
    number = number2;
    if (sign == '-')
    {
        length++;
        position++;
    }

    for (i = length; i >= 0 ; i--)
    {
        if (i == (length))
            r[i] = '\0';
        else if(i == (position))
            r[i] = '.';
        else if(sign == '-' && i == 0)
            r[i] = '-';
        else
        {
            r[i] = (number % 10) + '0';
            number /=10;
        }
    }
}

I recommend you just use the requests module.

It is much easier than the built in http clients: http://docs.python-requests.org/en/latest/index.html

Sample usage:

r = requests.get('http://www.thepage.com', proxies={"http":"http://myproxy:3129"})
thedata = r.content

IPython notebook uses MathJax to render LaTeX inside html/markdown. Just put your LaTeX math inside $$.

$$c = \sqrt{a^2 + b^2}$$

Or you can display LaTeX / Math output from Python, as seen towards the end of the notebook tour:

from IPython.display import display, Math, Latex
display(Math(r'F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx'))

This is for my comment on Andrey's answer but I cant include code in the comments.

Is you preference activity being called from you main activity? you could place this in the on resume...

@Override
protected void onResume() {
    if (!(PreferenceManager.getDefaultSharedPreferences(
            getApplicationContext()).getString("listLanguage", "en")
            .equals(langPreference))) {
        refresh();
    }
    super.onResume();
}

private void refresh() {
    finish();
    Intent myIntent = new Intent(Main.this, Main.class);
    startActivity(myIntent);
}

For full path names of changed files:

The server directive has to be in the http directive. It should not be outside of it.

Incase if you need detailed information, refer this.

actually, your answer is not complete as the values also depend on the wrapping container. In case of relative or linear layouts, the values behave like this:

• EXACTLY match_parent is EXACTLY + size of the parent
• AT_MOST wrap_content results in an AT_MOST MeasureSpec
• UNSPECIFIED never triggered

In case of an horizontal scroll view, your code will work.

Try git fetch --dry-run The manual (git help fetch) says:

You can use the sequence method list.extend to extend the list by multiple values from any kind of iterable, being it another list or any other thing that provides a sequence of values.

>>> lst = [1, 2]
>>> lst.append(3)
>>> lst.append(4)
>>> lst
[1, 2, 3, 4]

>>> lst.extend([5, 6, 7])
>>> lst.extend((8, 9, 10))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

So you can use list.append() to append a single value, and list.extend() to append multiple values.

My solution based on Mahdi Hijazi answer, but without any custom views:

Layout:

<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/scrollHorizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ScrollView 
        android:id="@+id/scrollVertical"
        android:layout_width="wrap_content"
        android:layout_height="match_parent" >

        <WateverViewYouWant/>

    </ScrollView>
</HorizontalScrollView>

Code (onCreate/onCreateView):

    final HorizontalScrollView hScroll = (HorizontalScrollView) value.findViewById(R.id.scrollHorizontal);
    final ScrollView vScroll = (ScrollView) value.findViewById(R.id.scrollVertical);
    vScroll.setOnTouchListener(new View.OnTouchListener() { //inner scroll listener         
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return false;
        }
    });
    hScroll.setOnTouchListener(new View.OnTouchListener() { //outer scroll listener         
        private float mx, my, curX, curY;
        private boolean started = false;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            curX = event.getX();
            curY = event.getY();
            int dx = (int) (mx - curX);
            int dy = (int) (my - curY);
            switch (event.getAction()) {
                case MotionEvent.ACTION_MOVE:
                    if (started) {
                        vScroll.scrollBy(0, dy);
                        hScroll.scrollBy(dx, 0);
                    } else {
                        started = true;
                    }
                    mx = curX;
                    my = curY;
                    break;
                case MotionEvent.ACTION_UP: 
                    vScroll.scrollBy(0, dy);
                    hScroll.scrollBy(dx, 0);
                    started = false;
                    break;
            }
            return true;
