Its better to build ObservableCollection and take advantage of it

public ObservableCollection<string> list = new ObservableCollection<string>();
list.Add("a");
list.Add("b");
list.Add("c");
this.cbx.ItemsSource = list;

cbx is comobobox name

Try using:

if(NewType* v = dynamic_cast<NewType*>(old)) {
   // old was safely casted to NewType
   v->doSomething();
}

This requires your compiler to have rtti support enabled.

EDIT: I've had some good comments on this answer!

Every time you need to use a dynamic_cast (or instanceof) you'd better ask yourself whether it's a necessary thing. It's generally a sign of poor design.

Typical workarounds is putting the special behaviour for the class you are checking for into a virtual function on the base class or perhaps introducing something like a visitor where you can introduce specific behaviour for subclasses without changing the interface (except for adding the visitor acceptance interface of course).

As pointed out dynamic_cast doesn't come for free. A simple and consistently performing hack that handles most (but not all cases) is basically adding an enum representing all the possible types your class can have and check whether you got the right one.

if(old->getType() == BOX) {
   Box* box = static_cast<Box*>(old);
   // Do something box specific
}

This is not good oo design, but it can be a workaround and its cost is more or less only a virtual function call. It also works regardless of RTTI is enabled or not.

Note that this approach doesn't support multiple levels of inheritance so if you're not careful you might end with code looking like this:

// Here we have a SpecialBox class that inherits Box, since it has its own type
// we must check for both BOX or SPECIAL_BOX
if(old->getType() == BOX || old->getType() == SPECIAL_BOX) {
   Box* box = static_cast<Box*>(old);
   // Do something box specific
}

In the PHP file first you need to register the session

 <? session_start();
     $_SESSION['id'] = $userData['user_id'];?>

And in each page of your php application you can retrive the session id

 <? session_start()
    id =  $_SESSION['id'];
   ?>

You're not actually going out after the values. You would need to gather them like this:

var title   = document.getElementById("title").value;
var name    = document.getElementById("name").value;
var tickets = document.getElementById("tickets").value;

You could put all of these in one array:

var myArray = [ title, name, tickets ];

Or many arrays:

var titleArr   = [ title ];
var nameArr    = [ name ];
var ticketsArr = [ tickets ];

Or, if the arrays already exist, you can use their .push() method to push new values onto it:

var titleArr = [];

function addTitle ( title ) {
  titleArr.push( title );
  console.log( "Titles: " + titleArr.join(", ") );
}

Your save button doesn't work because you refer to this.form, however you don't have a form on the page. In order for this to work you would need to have <form> tags wrapping your fields:

I've made several corrections, and placed the changes on jsbin: http://jsbin.com/ufanep/2/edit

The new form follows:

<form>
  <h1>Please enter data</h1>
  <input id="title" type="text" />
  <input id="name" type="text" />
  <input id="tickets" type="text" />
  <input type="button" value="Save" onclick="insert()" />
  <input type="button" value="Show data" onclick="show()" />
</form>
<div id="display"></div>

There is still some room for improvement, such as removing the onclick attributes (those bindings should be done via JavaScript, but that's beyond the scope of this question).

I've also made some changes to your JavaScript. I start by creating three empty arrays:

var titles  = [];
var names   = [];
var tickets = [];

Now that we have these, we'll need references to our input fields.

var titleInput  = document.getElementById("title");
var nameInput   = document.getElementById("name");
var ticketInput = document.getElementById("tickets");

I'm also getting a reference to our message display box.

var messageBox  = document.getElementById("display");

The insert() function uses the references to each input field to get their value. It then uses the push() method on the respective arrays to put the current value into the array.

Once it's done, it cals the clearAndShow() function which is responsible for clearing these fields (making them ready for the next round of input), and showing the combined results of the three arrays.

function insert ( ) {
 titles.push( titleInput.value );
 names.push( nameInput.value );
 tickets.push( ticketInput.value );

 clearAndShow();
}

This function, as previously stated, starts by setting the .value property of each input to an empty string. It then clears out the .innerHTML of our message box. Lastly, it calls the join() method on all of our arrays to convert their values into a comma-separated list of values. This resulting string is then passed into the message box.

function clearAndShow () {
  titleInput.value = "";
  nameInput.value = "";
  ticketInput.value = "";

  messageBox.innerHTML = "";

  messageBox.innerHTML += "Titles: " + titles.join(", ") + "<br/>";
  messageBox.innerHTML += "Names: " + names.join(", ") + "<br/>";
  messageBox.innerHTML += "Tickets: " + tickets.join(", ");
}

The final result can be used online at http://jsbin.com/ufanep/2/edit

<?php
  $min=1;
  $max=20;
  echo rand($min,$max);
?>

I believe that this would be the easiest and most intuitive way:

final = (df1.alias('df1').join(df2.alias('df2'),
                               on = df1['id'] == df2['id'],
                               how = 'inner')
                         .select('df1.*',
                                 'df2.other')
)

You need to add an event, before call your handleFunction like this:

function SingInContainer() {
..
..
handleClose = () => {
}

return (
    <SnackBar
        open={open}
        handleClose={() => handleClose}
        variant={variant}
        message={message}
        />
    <SignInForm/>
)

}

One advantage is that, we can non-sequentially process XML documents and unmarshal XML data from different sources like InputStream object, a URL, a DOM node...

You could try keeping track of your error due to rounding, and then rounding against the grain if the accumulated error is greater than the fractional portion of the current number.

13.62 -> 14 (+.38)
47.98 -> 48 (+.02 (+.40 total))
 9.59 -> 10 (+.41 (+.81 total))
28.78 -> 28 (round down because .81 > .78)
------------
        100

Not sure if this would work in general, but it seems to work similar if the order is reversed:

28.78 -> 29 (+.22)
 9.59 ->  9 (-.37; rounded down because .59 > .22)
47.98 -> 48 (-.35)
13.62 -> 14 (+.03)
------------
        100

I'm sure there are edge cases where this might break down, but any approach is going to be at least somewhat arbitrary since you're basically modifying your input data.

Well, your script throws an error and you just need to catch it (and/or prevent it from happening). I had the same error, for me it was an already used port (EADDRINUSE).

Remember: Javascript functions are CASE SENSITIVE.

I had a case where I'm pretty sure that my code would run smoothly. But still, got an error and I checked the Javascript console of Google Chrome to check what it is.

My error line is

opt.SetAttribute("value",values[a]);

And got the same error message:

Uncaught TypeError: undefined is not a function

Nothing seems wrong with the code above but it was not running. I troubleshoot for almost an hour and then compared it with my other running code. My error is that it was set to SetAttribute, which should be setAttribute.

pause command is what you looking for. If you looking ONLY the case when enter is hit you can abuse the runas command:

runas /user:# "" >nul 2>&1

the screen will be frozen until enter is hit.What I like more than set/p= is that if you press other buttons than enter they will be not displayed.

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

If the current directory is empty, you can do that with:

git clone git@github:me/name.git .

(Note the . at the end to specify the current directory.) Of course, this also creates the .git directory in your current folder, not just the source code from your project.

This optional [directory] parameter is documented in the git clone manual page, which points out that cloning into an existing directory is only allowed if that directory is empty.

Standard CSS3 rotate should work in IE9, but I believe you need to give it a vendor prefix, like so:

  -ms-transform: rotate(10deg);

It is possible that it may not work in the beta version; if not, try downloading the current preview version (preview 7), which is a later revision that the beta. I don't have the beta version to test against, so I can't confirm whether it was in that version or not. The final release version is definitely slated to support it.

I can also confirm that the IE-specific filter property has been dropped in IE9.

[Edit]
People have asked for some further documentation. As they say, this is quite limited, but I did find this page: http://css3please.com/ which is useful for testing various CSS3 features in all browsers.

But testing the rotate feature on this page in IE9 preview caused it to crash fairly spectacularly.

However I have done some independant tests using -ms-transform:rotate() in IE9 in my own test pages, and it is working fine. So my conclusion is that the feature is implemented, but has got some bugs, possibly related to setting it dynamically.

Another useful reference point for which features are implemented in which browsers is www.canIuse.com -- see http://caniuse.com/#search=rotation

[EDIT]
Reviving this old answer because I recently found out about a hack called CSS Sandpaper which is relevant to the question and may make things easier.

The hack implements support for the standard CSS transform for for old versions of IE. So now you can add the following to your CSS:

-sand-transform: rotate(10deg);

...and have it work in IE 6/7/8, without having to use the filter syntax. (of course it still uses the filter syntax behind the scenes, but this makes it a lot easier to manage because it's using similar syntax to other browsers)

The following doesn't work for JDK 1.7.0.07:

frame.setLocationRelativeTo(null);

It puts the top left corner at the center - not the same as centering the window. The other one doesn't work either, involving frame.getSize() and dimension.getSize():

Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
int x = (int) ((dimension.getWidth() - frame.getWidth()) / 2);
int y = (int) ((dimension.getHeight() - frame.getHeight()) / 2);
frame.setLocation(x, y);

The getSize() method is inherited from the Component class, and therefore frame.getSize returns the size of the window as well. Thus subtracting half the vertical and horizontal dimensions from the vertical and horizontal dimensions, to find the x,y coordinates of where to place the top-left corner, gives you the location of the center point, which ends up centering the window as well. However, the first line of the above code is useful, "Dimension...". Just do this to center it:

Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
JLabel emptyLabel = new JLabel("");
emptyLabel.setPreferredSize(new Dimension( (int)dimension.getWidth() / 2, (int)dimension.getHeight()/2 ));
frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
frame.setLocation((int)dimension.getWidth()/4, (int)dimension.getHeight()/4);

The JLabel sets the screen-size. It's in FrameDemo.java available on the java tutorials at the Oracle/Sun site. I set it to half the screen size's height/width. Then, I centered it by placing the top left at 1/4 of the screen size's dimension from the left, and 1/4 of the screen size's dimension from the top. You can use a similar concept.

Don't write if statements without a corresponding else. Once you add the else to your fragment you'll see that your true and false are in fact the last expressions of the function.

def balanceMain(elem: List[Char]): Boolean =
  {
    if (elem.isEmpty)
      if (count == 0)
        true
      else
        false
    else
      if (elem.head == '(')
        balanceMain(elem.tail, open, count + 1)
      else....

Plugin that scrolls (with animation) only when required

I've written a jQuery plugin that does exactly what it says on the tin (and also exactly what you require). The good thing is that it will only scroll container when element is actually off. Otherwise no scrolling will be performed.

It works as easy as this:

$("table tr:last").scrollintoview();

It automatically finds closest scrollable ancestor that has excess content and is showing scrollbars. So if there's another ancestor with overflow:auto but is not scrollable will be skipped. This way you don't need to provide scrollable element because sometimes you don't even know which one is scrollable (I'm using this plugin in my Sharepoint site where content/master is developer independent so it's beyond my control - HTML may change when site is operational so can scrollable containers).

You could try using Texter and create something unlikely like:

./p , triggered by space and replacing the text with %c

I just tested it and it works fine. The only gotcha is to use a rare sequence, as Texter cannot restrict this to just cmd.

There are probably other utilities of this kind which could work, and even AutoHotKey, upon which Texter is built could do it better, but Texter is easy :-)

There is an easier way to avoid the Strong Parameters at all, you just need to convert the parameters to a regular hash, as:

unlocked_params = ActiveSupport::HashWithIndifferentAccess.new(params)

model.create!(unlocked_params)

This defeats the purpose of strong parameters of course, but if you are in a situation like mine (I'm doing my own management of allowed params in another part of my system) this will get the job done.

In my case, i experienced this when i created an Empty C++ project on VS 2017 community edition. You will need to set the Subsystem to "Console (/SUBSYSTEM:CONSOLE)" under Configuration Properties.

1. Go to "View" then select "Property Manager"
2. Right click on the project/solution and select "Property". This opens a Test property page
3. Navigate to the linker then select "System"
4. Click on "SubSystem" and a drop down appears
5. Choose "Console (/SUBSYSTEM:CONSOLE)"
6. Apply and save
7. The next time you run your code with "CTRL +F5", you should see the output.

Using Query parameter

<a href="edit.jsp?userId=${user.id}" />  

Using Hidden variable .

<form method="post" action="update.jsp">  
...  
   <input type="hidden" name="userId" value="${user.id}">  

you can send Using Session object.

   session.setAttribute("userId", userid);

These values will now be available from any jsp as long as your session is still active.

   int userid = session.getAttribute("userId"); 

It just means it expects that as a key in your header data

import requests
endpoint = ".../api/ip"
data = {"ip": "1.1.2.3"}
headers = {"Authorization": "Bearer MYREALLYLONGTOKENIGOT"}

print(requests.post(endpoint, data=data, headers=headers).json())

Check where is the root folder of mysql with:

mysql_config

Simply choose your background color of your item and specify the opacity separatly:

div { background-color:#000; opacity:0.8; }

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

Events are pretty easy in C#, but the MSDN docs in my opinion make them pretty confusing. Normally, most documentation you see discusses making a class inherit from the EventArgs base class and there's a reason for that. However, it's not the simplest way to make events, and for someone wanting something quick and easy, and in a time crunch, using the Action type is your ticket.

Creating Events & Subscribing To Them

1. Create your event on your class right after your class declaration.

public event Action<string,string,string,string>MyEvent;

2. Create your event handler class method in your class.

private void MyEventHandler(string s1,string s2,string s3,string s4)
{
  Console.WriteLine("{0} {1} {2} {3}",s1,s2,s3,s4);
}

3. Now when your class is invoked, tell it to connect the event to your new event handler. The reason the += operator is used is because you are appending your particular event handler to the event. You can actually do this with multiple separate event handlers, and when an event is raised, each event handler will operate in the sequence in which you added them.

class Example
{
  public Example() // I'm a C# style class constructor
  {
    MyEvent += new Action<string,string,string,string>(MyEventHandler);
  }
}

4. Now, when you're ready, trigger (aka raise) the event somewhere in your class code like so:

MyEvent("wow","this","is","cool");

The end result when you run this is that the console will emit "wow this is cool". And if you changed "cool" with a date or a sequence, and ran this event trigger multiple times, you'd see the result come out in a FIFO sequence like events should normally operate.

In this example, I passed 4 strings. But you could change those to any kind of acceptable type, or used more or less types, or even remove the <...> out and pass nothing to your event handler.

And, again, if you had multiple custom event handlers, and subscribed them all to your event with the += operator, then your event trigger would have called them all in sequence.

Identifying Event Callers

But what if you want to identify the caller to this event in your event handler? This is useful if you want an event handler that reacts with conditions based on who's raised/triggered the event. There are a few ways to do this. Below are examples that are shown in order by how fast they operate:

Option 1. (Fastest) If you already know it, then pass the name as a literal string to the event handler when you trigger it.

Option 2. (Somewhat Fast) Add this into your class and call it from the calling method, and then pass that string to the event handler when you trigger it:

private static string GetCaller([System.Runtime.CompilerServices.CallerMemberName] string s = null) => s;

Option 3. (Least Fast But Still Fast) In your event handler when you trigger it, get the calling method name string with this:

string callingMethod = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod().ReflectedType.Name.Split('<', '>')[1];

Unsubscribing From Events

You may have a scenario where your custom event has multiple event handlers, but you want to remove one special one out of the list of event handlers. To do so, use the -= operator like so:

MyEvent -= MyEventHandler;

A word of minor caution with this, however. If you do this and that event no longer has any event handlers, and you trigger that event again, it will throw an exception. (Exceptions, of course, you can trap with try/catch blocks.)

Clearing All Events

Okay, let's say you're through with events and you don't want to process any more. Just set it to null like so:

MyEvent = null;

The same caution for Unsubscribing events is here, as well. If your custom event handler no longer has any events, and you trigger it again, your program will throw an exception.

Piece of cake:

arr := []byte("That's all folks!!")

I set iframe src attribute later in my app. To get rid of the cached content inside iframe at the start of the application I simply do:

myIframe.src = "";

... somewhere in the beginning of js code (for instance in jquery $() handler)

Use jquery cookie plugin, the link as working today: https://github.com/js-cookie/js-cookie

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

The same way you declare any other variable, just use the bit type:

DECLARE @MyVar bit
Set @MyVar = 1  /* True */
Set @MyVar = 0  /* False */

SELECT * FROM [MyTable] WHERE MyBitColumn = @MyVar

Be careful when accessing DateTime.Now twice, as it's possible for the calls to straddle midnight and you'll get wacky results on rare occasions and be left scratching your head.

To be safe, you should assign DateTime.Now to a local variable first if you're going to use it more than once:

var now = DateTime.Now;
var time = now.ToString("hh:mm:ss tt");
var date = now.ToString("MM/dd/yy");

Note the use of lower case "hh" do display hours from 00-11 even in the afternoon, and "tt" to show AM/PM, as the question requested. If you want 24 hour clock 00-23, use "HH".

I think the best way to do this is to use event.preventDefault() because if some exception is raised in the handler, then the return false statement will be skipped and the behavior will be opposite to what you want.

But if you are sure that the code won't trigger any exceptions, then you can go with any of the method you wish.

If you still want to go with the return false, then you can put your entire handler code in a try catch block like below:

$('a').click(function (e) {
  try{
      your code here.........
  }
   catch(e){}
  return false;
});

USE master;
GO
ALTER DATABASE Database_Name
    SET ENABLE_BROKER WITH ROLLBACK IMMEDIATE;
GO
USE Database_Name;
GO

This was the best way for me. You can retrieve all existing files (be it symbolic links or normal):

os.path.lexists(path)

Return True if path refers to an existing path. Returns True for broken symbolic links. Equivalent to exists() on platforms lacking os.lstat().

New in version 2.4.

This will also work:

<Hyperlink Command="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl},
                             Path=DataContext.AllowItemCommand}" />

ListView will inherit its DataContext from Window, so it's available at this point, too.
And since ListView, just like similar controls (e. g. Gridview, ListBox, etc.), is a subclass of ItemsControl, the Binding for such controls will work perfectly.

I came across the same error after updating to the latest version of JQuery. Therefore I updated the jquery file I was working on, as stated in a previous answer, so it said .on("load") instead of .load().

This fix isn't very stable and sometimes it didn't work for me. Therefore to fix this issue you should update your code from:

    .load();

to

    .trigger("load");

I got this fix from the following source: https://github.com/stevenwanderski/bxslider-4/pull/1024

You can find a sample code about sharpening image using "unsharp mask" algorithm at OpenCV Documentation.

Changing values of sigma,threshold,amount will give different results.

// sharpen image using "unsharp mask" algorithm
Mat blurred; double sigma = 1, threshold = 5, amount = 1;
GaussianBlur(img, blurred, Size(), sigma, sigma);
Mat lowContrastMask = abs(img - blurred) < threshold;
Mat sharpened = img*(1+amount) + blurred*(-amount);
img.copyTo(sharpened, lowContrastMask);

You could give it a try. The problem is that Windows inserts a carriage return as well as a line feed when given a new line. Unix-systems just insert a line feed. So the extra carriage return character could be the reason why your eclipse messes up with the newlines.

Grab one or two files from your project and convert them. You could use Notepad++ to do so. Just open the file, go to Format->Convert to Unix (when you are using windows).

In Linux just try this on a command line:

sed 's/$'"/`echo \\\r`/" yourfile.java > output.java

The main problem in your case would be failure of accessing \\localhost\c$

If you get an error while trying to access the Windows hidden C share (C$):

C:\> net use \\localhost\c$
System error 53 has occurred.

The network path was not found.

You may find the following articles useful: KB254210 and KB951016.

A simple thing is just to make sure your TCP/IP NetBIOS Helper and Server services are running (Start-Run, services.msc) and try again:

C:\> net use \localhost\c$
The command completed successfully.

Of course, your user must be either an administrator or be part of the administrator group.

If it still fails, manually edit the registry (Start-Run, regedit). Browse to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

and create a new DWORD value LocalAccountTokenFilterPolicy set to 1

After solving this issue and installing Oracle Database Server, you can disable back your TCP/IP NetBIOS Helper service if you don't need it anymore.

For others:
If you don't have the problem with \\localhost\c$, then you might have the other problem with your username as the others stated (e.g. username with '_' in it):
This will get solved by changing TEMP and TMP environment variables from a command line and then running setup.exe from there.

If this still doesn't work:
Try running setup.exe with "-debug" option and see what happens in there.
You may also want to check what's in the .log files created in your %TEMP% folder (e.g. ssproiut_%number%.log)

You can run the dropdb command from the command line:

dropdb 'database name'

Note that you have to be a superuser or the database owner to be able to drop it.

You can also check the pg_stat_activity view to see what type of activity is currently taking place against your database, including all idle processes.

SELECT * FROM pg_stat_activity WHERE datname='database name';

Note that from PostgreSQL v13 on, you can disconnect the users automatically with

DROP DATABASE dbname FORCE;

or

dropdb -f dbname

Using bash:

readarray -t LINES < file.txt
COUNT=${#LINES[@]}
for I in "${!LINES[@]}"; do
    INDEX=$(( (I * 12 - 1) / COUNT + 1 ))
    echo "${LINES[I]}" >> "file${INDEX}.txt"
done

Using awk:

awk '{
    a[NR] = $0
}
END {
    for (i = 1; i in a; ++i) {
        x = (i * 12 - 1) / NR + 1
        sub(/\..*$/, "", x)
        print a[i] > "file" x ".txt"
    }
}' file.txt

Unlike split this one makes sure that number of lines are most even.

Extract the table and pipe it directly to the target database:

pg_dump -t table_to_copy source_db | psql target_db

Note: If the other database already has the table set up, you should use the -a flag to import data only, else you may see weird errors like "Out of memory":

pg_dump -a -t my_table my_db | psql target_db

I've made an alternative to the other good answers on here that uses PowerShell, but mine also saves the list to a file. Will share it here in case anyone else needs wants something like that.

Warning: Code overwrites "longfilepath.txt" in the current working directory. I know it's unlikely you'd have one already, but just in case!

Purposely wanted it in a single line:

Out-File longfilepath.txt ; cmd /c "dir /b /s /a" | ForEach-Object { if ($_.length -gt 250) {$_ | Out-File -append longfilepath.txt}}

Detailed instructions:

1. Run PowerShell
2. Traverse to the directory you want to check for filepath lengths (C: works)
3. Copy and paste the code [Right click to paste in PowerShell, or Alt + Space > E > P]
4. Wait until it's done and then view the file: cat longfilepath.txt | sort

Explanation:

Out-File longfilepath.txt ; – Create (or overwrite) a blank file titled 'longfilepath.txt'. Semi-colon to separate commands.

cmd /c "dir /b /s /a" | – Run dir command on PowerShell, /a to show all files including hidden files. | to pipe.

ForEach-Object { if ($_.length -gt 250) {$_ | Out-File -append longfilepath.txt}} – For each line (denoted as $_), if the length is greater than 250, append that line to the file.

Just use the formula

120 = (HOUR(A8)*3600+MINUTE(A8)*60+SECOND(A8))/60

All of these answers miss a very important aspect!

By using .html or innerHtml or outerHtml you are not actually using the referenced element. You are using a copy of the element's html. This has some serious draw backs.

1. You can't use any ids because the ids will be duplicated.
2. If you load the contents every time that the popover is shown you will lose all of the user's input.

What you want to do is load the object itself into the popover.

https://jsfiddle.net/shrewmouse/ex6tuzm2/4/

HTML:

<h1> Test </h1>

<div><button id="target">click me</button></div>

<!-- This will be the contents of our popover -->
<div class='_content' id='blah'>
<h1>Extra Stuff</h1>
<input type='number' placeholder='number'/>
</div>

JQuery:

$(document).ready(function() {

    // We don't want to see the popover contents until the user clicks the target.
    // If you don't hide 'blah' first it will be visible outside of the popover.
    //
    $('#blah').hide();

    // Initialize our popover
    //
    $('#target').popover({
        content: $('#blah'), // set the content to be the 'blah' div
        placement: 'bottom',
        html: true
    });
    // The popover contents will not be set until the popover is shown.  Since we don't 
    // want to see the popover when the page loads, we will show it then hide it.
    //
    $('#target').popover('show');
    $('#target').popover('hide');

    // Now that the popover's content is the 'blah' dive we can make it visisble again.
    //
    $('#blah').show();


});

I had similar issue with below error:

Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.

It started when I added below dependency in Gradle:

    implementation 'com.google.android.gms:play-services-tagmanager:11.0.4'

I fixed it by upgrading the dependency version as below:

implementation 'com.google.android.gms:play-services-tagmanager:17.0.0'

Whenever you're confused, I would suggest consulting the Javadoc as the first place for your clarification.

From the javadoc about System, here's what the doc says:

public final class System
extends Object

The System class contains several useful class fields and methods. It cannot be instantiated.
Among the facilities provided by the System class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.

Since:
JDK1.0

Regarding System.out

public static final PrintStream out
The "standard" output stream. This stream is already open and ready to accept output data. Typically this stream corresponds to display output or another output destination specified by the host environment or user.
For simple stand-alone Java applications, a typical way to write a line of output data is:

     System.out.println(data)

Just my 2 cents, had:

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

at the end of body, wasn't working, had to add crossorigin="anonymous" and now it's working, Bootstrap version 3.3.6. ...

Most used way is, anonymous declaration

    Button send = (Button) findViewById(R.id.buttonSend);
    send.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // handle click
        }
    });

Also you can create View.OnClickListener object and set it to button later, but you still need to override onClick method for example

View.OnClickListener listener = new View.OnClickListener(){
     @Override
        public void onClick(View v) {
            // handle click
        }
}   
Button send = (Button) findViewById(R.id.buttonSend);
send.setOnClickListener(listener);

When your activity implements OnClickListener interface you must override onClick(View v) method on activity level. Then you can assing this activity as listener to button, because it already implements interface and overrides the onClick() method

public class MyActivity extends Activity implements View.OnClickListener{


    @Override
    public void onClick(View v) {
        // handle click
    }


    @Override
    public void onCreate(Bundle b) {
        Button send = (Button) findViewById(R.id.buttonSend);
        send.setOnClickListener(this);
    }

}

(imho) 4-th approach used when multiple buttons have same handler, and you can declare one method in activity class and assign this method to multiple buttons in xml layout, also you can create one method for one button, but in this case I prefer to declare handlers inside activity class.

In my case, I took a dependency on a service that had no dependencies and therefore I did not add a constructor() function to the service class. I added a parameterless constructor to the dependent service class and everything started working.

You need to use HttpContext.Current.Request.Cookies, not Response.Cookies.

Side note: cookies are copied to Request on Response.Cookies.Add, which makes check on either of them to behave the same for newly added cookies. But incoming cookies are never reflected in Response.

This behavior is documented in HttpResponse.Cookies property:

After you add a cookie by using the HttpResponse.Cookies collection, the cookie is immediately available in the HttpRequest.Cookies collection, even if the response has not been sent to the client.

Once a thread is started, it is not necessary to retain a reference to the Thread object. The thread continues to execute until the thread procedure ends.

new Thread(new ThreadStart(SecondFoo)).Start();

I had a similar issue and blogged about it here. I started with the regular expression for alpha numerics, then added in the few basic punctuation characters I liked:

select dump(a,1016), a, b
from
 (select regexp_replace(COLUMN,'[[:alnum:]/''%()> -.:=;[]','') a,
         COLUMN b
  from TABLE)
where a is not null
order by a;

I used dump with the 1016 variant to give out the hex characters I wanted to replace which I could then user in a utl_raw.cast_to_varchar2.

   <p id="text" onclick="func()">
    Click on text to change
</p>
<script>
function func()
{
    document.getElementById("text").style.color="red";
    document.getElementById("text").style.font="calibri";
}
</script>

NULL == NULL -> false (at least in DBMSs)

So you wouldn't be able to retrieve any relationships using a NULL value even with additional columns with real values.

For me, adding the following block of code under <dependency management><dependencies> solved the problem.

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.1-b06</version>
</dependency>

as your service is already setup, simply add a broadcast receiver in your service:

private final BroadcastReceiver receiver = new BroadcastReceiver() {
   @Override
   public void onReceive(Context context, Intent intent) {
      String action = intent.getAction();
      if(action.equals("android.provider.Telephony.SMS_RECEIVED")){
        //action for sms received
      }
      else if(action.equals(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED)){
           //action for phone state changed
      }     
   }
};

in your service's onCreate do this:

IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
filter.addAction("your_action_strings"); //further more
filter.addAction("your_action_strings"); //further more

registerReceiver(receiver, filter);

and in your service's onDestroy:

unregisterReceiver(receiver);

and you are good to go to receive broadcast for what ever filters you mention in onCreate. Make sure to add any permission if required. for e.g.

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

It's the array that's causing trouble in:

void print_graph(g_node graph_node[], double weight[][], int nodes);

The second and subsequent dimensions must be given:

void print_graph(g_node graph_node[], double weight[][32], int nodes);

Or you can just give a pointer to pointer:

void print_graph(g_node graph_node[], double **weight, int nodes);

However, although they look similar, those are very different internally.

If you're using C99, you can use variably-qualified arrays. Quoting an example from the C99 standard (section §6.7.5.2 Array Declarators):

void fvla(int m, int C[m][m]); // valid: VLA with prototype scope

void fvla(int m, int C[m][m])  // valid: adjusted to auto pointer to VLA
{
    typedef int VLA[m][m];     // valid: block scope typedef VLA
    struct tag {
        int (*y)[n];           // invalid: y not ordinary identifier
        int z[n];              // invalid: z not ordinary identifier
    };
    int D[m];                  // valid: auto VLA
    static int E[m];           // invalid: static block scope VLA
    extern int F[m];           // invalid: F has linkage and is VLA
    int (*s)[m];               // valid: auto pointer to VLA
    extern int (*r)[m];        // invalid: r has linkage and points to VLA
    static int (*q)[m] = &B;   // valid: q is a static block pointer to VLA
}

Question in comments

[...] In my main(), the variable I am trying to pass into the function is a double array[][], so how would I pass that into the function? Passing array[0][0] into it gives me incompatible argument type, as does &array and &array[0][0].

In your main(), the variable should be:

double array[10][20];

or something faintly similar; maybe

double array[][20] = { { 1.0, 0.0, ... }, ... };

You should be able to pass that with code like this:

typedef struct graph_node
{
    int X;
    int Y;
    int active;
} g_node;

void print_graph(g_node graph_node[], double weight[][20], int nodes);

int main(void)
{
    g_node g[10];
    double array[10][20];
    int n = 10;

    print_graph(g, array, n);
    return 0;
}

That compiles (to object code) cleanly with GCC 4.2 (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)) and also with GCC 4.7.0 on Mac OS X 10.7.3 using the command line:

/usr/bin/gcc -O3 -g -std=c99 -Wall -Wextra -c zzz.c

This should handle addition/subtraction, just put a negative value in to subtract and a positive value to add. This also solves the month crossover problem.

function monthAdd(date, month) {
    var temp = date;
    temp = new Date(date.getFullYear(), date.getMonth(), 1);
    temp.setMonth(temp.getMonth() + (month + 1));
    temp.setDate(temp.getDate() - 1); 

    if (date.getDate() < temp.getDate()) { 
        temp.setDate(date.getDate()); 
    }

    return temp;    
}

Use runlike from git repository https://github.com/lavie/runlike

To install runlike

pip install runlike

As it accept container id as an argument so to extract container id use following command

docker ps -a -q

You are good to use runlike to extract complete docker run command with following command

runlike <docker container ID>

&& is new in C++11, and it signifies that the function accepts an RValue-Reference -- that is, a reference to an argument that is about to be destroyed.

You may also use pyplot.text (see here).

def plot_embeddings(M_reduced, word2Ind, words):
    """

        plt.scatter(x, y, marker='x', color='red')
        plt.text(x+.03, y+.03, word, fontsize=9)
    plt.show()

plot_embeddings(M_reduced_plot_test, word2Ind_plot_test, words)

It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)  

$langs = Language::all()->toArray();
return View::make('NAATIMockTest.Admin.Language.index', [
    'langs' => $langs
]);

then in view

<script type="text/javascript">
    var langs = {{json_encode($langs)}};
    console.log(langs);
</script>

Its not pretty tho

You don't need pip for installing Beautiful Soup - you can just download it and run python setup.py install from the directory that you have unzipped BeautifulSoup in (assuming that you have added Python to your system PATH - if you haven't and you don't want to you can run C:\Path\To\Python27\python "C:\Path\To\BeautifulSoup\setup.py" install)

However, you really should install pip - see How to install pip on Windows for how to do that best (via @MartijnPieters comment)

$total_ratings is an array, which you can't use for a division.

From above:

$total_ratings = mysqli_fetch_array($result);

Curly braces. Passing keyword arguments into dict(), though it works beautifully in a lot of scenarios, can only initialize a map if the keys are valid Python identifiers.

This works:

a = {'import': 'trade', 1: 7.8}

a = dict({'import': 'trade', 1: 7.8})

This won't work:

a = dict(import='trade', 1=7.8)

It will result in the following error:

    a = dict(import='trade', 1=7.8)
             ^

Apache Virtual Host documentation Setting up a virtual host (vhost) provides several benefits:

• Virtual Hosts make URLs cleaner – localhost/mysite vs mysite.local.
• Virtual Hosts make permissions easier – restrict access for a single vhost on a local network vs permitting access to all sites on your local network.
• Some applications require a “.” in the URL (ahem Magento). While you can setup localhost.com/mysite by editing the Windows hosts file, creating a vhost is a better solution.

VirtualHost Directive Contains directives that apply only to a specific hostname or IP address

Location Directive Applies the enclosed directives only to matching URLs

Take a look at this Github issue:

https://github.com/facebook/react-native/issues/231

They are trying to require non-JSON files, in particular JSON. There is no method of doing this right now, so you either have to use AsyncStorage as @CocoOS mentioned, or you could write a small native module to do what you need to do.

I have found it best to avoid forceUpdate(). One way to force re-render is to add dependency of render() on a temporary external variable and change the value of that variable as and when needed.

Here's a code example:

class Example extends Component{
   constructor(props){
      this.state = {temp:0};

      this.forceChange = this.forceChange.bind(this);
   }

   forceChange(){
      this.setState(prevState => ({
          temp: prevState.temp++
      })); 
   }

   render(){
      return(
         <div>{this.state.temp &&
             <div>
                  ... add code here ...
             </div>}
         </div>
      )
   }
}

Call this.forceChange() when you need to force re-render.

In some browsers you will face problems if you are not giving an href attribute. I suggest you to write your code something like this:

<a href="#" onclick="yourcode();return false;">Link</a>

you can replace yourcode() with your own function or logic,but do remember to add return false; statement at the end.

You might output your DataFrame as a csv file and then use mysqlimport to import your csv into your mysql.

EDIT

Seems pandas's build-in sql util provide a write_frame function but only works in sqlite.

I found something useful, you might try this

<input type='submit' value='Submit' onclick='this.form.action="somethingelse";' />

Or you can modify it from outside the form, with javascript the normal way:

 document.getElementById('form_id').action = 'somethingelse';

Use the setAttribute method:

document.getElementById('item1').setAttribute('data', "icon: 'base2.gif', url: 'output.htm', target: 'AccessPage', output: '1'");

But you really should be using data followed with a dash and with its property, like:

<li ... data-icon="base.gif" ...>

And to do it in JS use the dataset property:

document.getElementById('item1').dataset.icon = "base.gif";

shutil.copy and shutil.copy2 are copying files.

shutil.copytree copies a folder with all the files and all subfolders. shutil.copytree is using shutil.copy2 to copy the files.

So the analog to cp -r you are saying is the shutil.copytree because cp -r targets and copies a folder and its files/subfolders like shutil.copytree. Without the -r cp copies files like shutil.copy and shutil.copy2 do.

Here you have an example of two ways of doing a vertical alignment. I use them and they work pretty well. One is using absolute positioning and the other using flexbox.

Vertical Align Example

Using flexbox, you can align an element by itself inside another element with display: flex; using align-self. If you need to align it also horizontally, you can use align-items and justify-content in the container.

If you don't want to use flexbox, you can use the position property. If you make the container relative and the content absolute, the content will be able to move freely inside the container. So if you use top: 0; and left: 0; in the content, it will be positioned at the top left corner of the container.

Then, to align it, you just need to change the top and left references to 50%. This will position the content at the container center from the top left corner of the content.

So you need to correct this translating the content half its size to the left and top.

Some online API's work pretty well: ocr.space and Google Cloud Vision. Both of these are free, as long as you do less than 1000 OCR's per month. You can drag & drop an image to do a quick manual test to see how they perform for your images.

I find OCR.space easier to use (no messing around with nuget libraries), but, for my purpose, Google Cloud Vision provided slightly better results than OCR.space.

Google Cloud Vision example:

GoogleCredential cred = GoogleCredential.FromJson(json);
Channel channel = new Channel(ImageAnnotatorClient.DefaultEndpoint.Host, ImageAnnotatorClient.DefaultEndpoint.Port, cred.ToChannelCredentials());
ImageAnnotatorClient client = ImageAnnotatorClient.Create(channel);
Image image = Image.FromStream(stream);

EntityAnnotation googleOcrText = client.DetectText(image).First();
Console.Write(googleOcrText.Description);

OCR.space example:

string uri = $"https://api.ocr.space/parse/imageurl?apikey=helloworld&url={imageUri}";
string responseString = WebUtilities.DoGetRequest(uri);
OcrSpaceResult result = JsonConvert.DeserializeObject<OcrSpaceResult>(responseString);
if ((!result.IsErroredOnProcessing) && !String.IsNullOrEmpty(result.ParsedResults[0].ParsedText))
  return result.ParsedResults[0].ParsedText;

If you using compare To method of the Comparable interface in any class. This can be used to arrange the string in Lexicographically.

public class Student() implements Comparable<Student>{

public int compareTo(Object obj){
if(this==obj){
    return 0;
}
if(obj!=null){
    String objName = ((Student)obj).getName();
    return this.name.comapreTo.(objName);
}
}

You can use T-Regx library, that doesn't need delimiters

pattern('^([0-9]+)$')->match($input);

Polish-> English (VS on MAC) answer: When I started a project and was forced to download Visual Studio, went to their page and saw that Microsoft logo I knew there would be problems... And here it is. It occurred difficult to change the language of VS on Mac. My OS is purely English and only because of the fact I downloaded it using a browser with Polish set as a default language I got the wrong version. I had to reinstall the version to the newest and then Visual Studio Community -> Preferences(in the environment section) -> Visual Style-> User Interface Language.

It translates to polish: Visual Studio Community -> Preferencje -> Styl Wizualny w sekcji Srodowisko -> Jezyk interfejsu uzytkownika -> English.

If you don't see such an option then, as I was, you are forced to upgrade this crappy VS to the newest version.

You can do this with PowerShell:

Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\' -Name InstallDate |
    Select-Object -Property @{n='InstallDate';e={[DateTime]::new(1970,1,1,0,0,0,0,'UTC').AddSeconds($_.InstallDate).ToLocalTime()}}

No, but you can install an isolated Python build (such as ActivePython) under your $HOME directory.

This approach is the fastest, and doesn't require you to compile Python yourself.

(as a bonus, you also get to use ActiveState's binary package manager)

out.write(c.toString());
out.newLine();

here is a simple solution, I hope it works

EDIT: I was using "\n" which was obviously not recommended approach, modified answer.

There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.

When you define your list as:

List myList = new ArrayList();

you can only call methods and reference members that are defined in the List interface. If you define it as:

ArrayList myList = new ArrayList();

you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.

Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).

That's called polymorphism. You can read up on it.

It is a duplicate of this question, with an answer that contains a time measurement of the different methods.

Conclusion: Use [void] or > $null.

OCTOBER 2016 UPDATE

With support library v25.0.0 there finally is a default implementation of basic horizontal and vertical dividers available!

https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration.html

Okay, how about a CSS answer! We use display: table. Then each of the divs are rows, and finally we apply height of 100% to middle 'row' and voilà.

http://jsfiddle.net/NfmX3/3/

body { display: table; }
div { display: table-row; }
#content {
    width:450px; 
    margin:0 auto;
    text-align: center;
    background-color: blue;
    color: white;
    height: 100%;
}

In case you want to use bootstrap radio to check one of them depends on the result of your checked var in the .ts file.

component.html

<h1>Radio Group #1</h1>
<div class="btn-group btn-group-toggle" data-toggle="buttons" >
   <label [ngClass]="checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio1" value="option1" type="radio"> TRUE
   </label>
   <label [ngClass]="!checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio2" value="option2" type="radio"> FALSE
   </label>
</div>

component.ts file

@Component({
  selector: '',
  templateUrl: './.component.html',
  styleUrls: ['./.component.css']
})
export class radioComponent implements OnInit {
  checked = true;
}

Consider using System.Windows.Forms.Timer instead of System.Threading.Timer for a GUI application, for timers that are based on the Windows message queue instead of on dedicated threads or the thread pool.

In your scenario, for the purpose of periodic updates of UI, it seems particularly appropriate since you don't really have a background work or long calculation to perform. You just want to do periodic small tasks that have to happen on the UI thread anyway.

You can increase body size in nginx configuration file as

sudo nano /etc/nginx/nginx.conf

client_max_body_size 100M;

Restart nginx to apply the changes.

sudo service nginx restart

I don't see this mentioned in any of the other answers. If you're passing around an Exception object for whatever reason...

In Python 3.5+ you can get a trace from an Exception object using traceback.TracebackException.from_exception(). For example:

import traceback


def stack_lvl_3():
    raise Exception('a1', 'b2', 'c3')


def stack_lvl_2():
    try:
        stack_lvl_3()
    except Exception as e:
        # raise
        return e


def stack_lvl_1():
    e = stack_lvl_2()
    return e

e = stack_lvl_1()

tb1 = traceback.TracebackException.from_exception(e)
print(''.join(tb1.format()))

However, the above code results in:

Traceback (most recent call last):
  File "exc.py", line 10, in stack_lvl_2
    stack_lvl_3()
  File "exc.py", line 5, in stack_lvl_3
    raise Exception('a1', 'b2', 'c3')
Exception: ('a1', 'b2', 'c3')

This is just two levels of the stack, as opposed to what would have been printed on screen had the exception been raised in stack_lvl_2() and not intercepted (uncomment the # raise line).

As I understand it, that's because an exception records only the current level of the stack when it is raised, stack_lvl_3() in this case. As it's passed back up through the stack, more levels are being added to its __traceback__. But we intercepted it in stack_lvl_2(), meaning all it got to record was levels 3 and 2. To get the full trace as printed on stdout we'd have to catch it at the highest (lowest?) level:

import traceback


def stack_lvl_3():
    raise Exception('a1', 'b2', 'c3')


def stack_lvl_2():
    stack_lvl_3()


def stack_lvl_1():
    stack_lvl_2()


try:
    stack_lvl_1()
except Exception as exc:
    tb = traceback.TracebackException.from_exception(exc)

print('Handled at stack lvl 0')
print(''.join(tb.stack.format()))

Which results in:

Handled at stack lvl 0
  File "exc.py", line 17, in <module>
    stack_lvl_1()
  File "exc.py", line 13, in stack_lvl_1
    stack_lvl_2()
  File "exc.py", line 9, in stack_lvl_2
    stack_lvl_3()
  File "exc.py", line 5, in stack_lvl_3
    raise Exception('a1', 'b2', 'c3')

Notice that the stack print is different, the first and last lines are missing. Because it's a different format().

Intercepting the exception as far away from the point where it was raised as possible makes for simpler code while also giving more information.

div tags are used to style the webpage so that it look visually appealing for the users or audience of the website. using container-div in html will make the website look more professional and attractive and therefore more people will want to explore your page.

For Windows 7 using the Git found here (it uses MinGW, not Cygwin):

1. In the windows explorer, right-click your id_rsa file and select Properties
2. Select the Security tab and click Edit...
3. Check the Deny box next to Full Control for all groups EXCEPT Administrators
4. Retry your Git command

I think writing PHP into an .html file is confusing and anti-natural. Why would you do that??

Anyway, if what you want is to execute PHP files and show them as .html in the address bar, an easiest solution would be using .php as normal, and write a rule in your .htaccess like this:

RewriteRule ^([^.]+)\.html$ $1.php [L]

Your csv is malformed. The output is not three loopings but just one output. To ensure that this is a single loop, add a counter and increment it with every loop. It should only count to one.

This is what your code sees

0,Filipe,19,M\n1,Maria,20,F\n2,Walter,60,M

Try this

0,Filipe,19,M
1,Maria,20,F
2,Walter,60,M


while(file.good())
{

    getline(file, ID, ',');
    cout << "ID: " << ID << " " ; 

    getline(file, nome, ',') ;
    cout << "User: " << nome << " " ;

    getline(file, idade, ',') ;
    cout << "Idade: " << idade << " "  ; 

    getline(file, genero) ; \\ diff
    cout << "Sexo: " <<  genero;\\diff


}

IIS version 8.5 +

To enable Event Tracing for Windows for your website/application

1. Go to Logging and ensure either ETW event only or Both log file and ETW event ...is selected.

2. Enable the desired Recycle logs in the Advanced Settings for the Application Pool:

3. Go to the default Custom View: WebServer filters IIS logs:

Custom Views > ServerRoles > Web Server

4. ... or System logs:

Windows Logs > System

For anyone who may be interested, another approach is using @media queries to scale the buttons on different viewport widths..

A good bet is to utilize Rails' Arel SQL manager, which explicitly supports case-insensitive ActiveRecord queries:

t = Guide.arel_table Guide.where(t[:title].matches('%attack')) 

Here's an interesting blog post regarding the portability of case-insensitive queries using Arel. It's worth a read to understand the implications of utilizing Arel across databases.

As of SLF4J 1.6.0, in the presence of multiple parameters and if the last argument in a logging statement is an exception, then SLF4J will presume that the user wants the last argument to be treated as an exception and not a simple parameter. See also the relevant FAQ entry.

So, writing (in SLF4J version 1.7.x and later)

 logger.error("one two three: {} {} {}", "a", "b", 
              "c", new Exception("something went wrong"));

or writing (in SLF4J version 1.6.x)

 logger.error("one two three: {} {} {}", new Object[] {"a", "b", 
              "c", new Exception("something went wrong")});

will yield

one two three: a b c
java.lang.Exception: something went wrong
    at Example.main(Example.java:13)
    at java.lang.reflect.Method.invoke(Method.java:597)
    at ...

The exact output will depend on the underlying framework (e.g. logback, log4j, etc) as well on how the underlying framework is configured. However, if the last parameter is an exception it will be interpreted as such regardless of the underlying framework.

In case of SQL Server, this should work

SELECT CONVERT(VARCHAR(8),GETDATE(),108) AS HourMinuteSecond

as per docs:

• "json": Evaluates the response as JSON and returns a JavaScript object. In jQuery 1.4 the JSON data is parsed in a strict manner; any malformed JSON is rejected and a parse error is thrown. (See json.org for more information on proper JSON formatting.)
• "text": A plain text string.

For the Javadoc tag @see, you don't need to use @link; Javadoc will create a link for you. Try

@see com.my.package.Class#method()

Here's more info about @see.

Add this if you want the number of citations to appear in order in the document they will only be unsorted in the reference page:

\bibliographystyle{unsrt}

OP didn't specify if the object is a nodeList, if it is then you can just use length method on it directly. Example:

buttons = document.querySelectorAll('[id=button)) {
console.log('Found ' + buttons.length + ' on the screen'); 

Peer authentication means that postgres asks the operating system for your login name and uses this for authentication. To login as user "dev" using peer authentication on postgres, you must also be the user "dev" on the operating system.

You can find details to the authentication methods in the Postgresql documentation.

Hint: If no authentication method works anymore, disconnect the server from the network and use method "trust" for "localhost" (and double check that your server is not reachable through the network while method "trust" is enabled).

You just need to rename ib_logfile0 and ib_logfile1 as ib_logfile_0 and ib_logfile_1. Then your problem would be solved.

You don't have to force yourself to remember differences between them. Think of how you actually made a commit.

1. Make some changes.

2. git add .

3. git commit -m "I did Something"

Soft, Mixed and Hard is the way enabling you to give up the operations you did from 3 to 1.

• Soft "pretended" to never see you have did git commit.
• Mixed "pretended" to never see you have did git add .
• Hard "pretended" to never see you have made file changes.

How about for example https://github.com/joyent/node/wiki/modules#wiki-tcp. A very quick summary =>

• https://github.com/visionmedia/superagent
• https://github.com/mikeal/request

for (Iterator<String> i = someIterable.iterator(); i.hasNext();) {
    String item = i.next();
    System.out.println(item);
}

Note that if you need to use i.remove(); in your loop, or access the actual iterator in some way, you cannot use the for ( : ) idiom, since the actual iterator is merely inferred.

As was noted by Denis Bueno, this code works for any object that implements the Iterable interface.

Also, if the right-hand side of the for (:) idiom is an array rather than an Iterable object, the internal code uses an int index counter and checks against array.length instead. See the Java Language Specification.

You can use fiddler web debugger to import the HAR and then it is very easy from their on... Ctrl+A (select all) then Ctrl+c (copy summary) then paste in excel and have fun

SQLAlchemy introduced that in version 1.0.0:

Bulk operations - SQLAlchemy docs

With these operations, you can now do bulk inserts or updates!

For instance, you can do:

s = Session()
objects = [
    User(name="u1"),
    User(name="u2"),
    User(name="u3")
]
s.bulk_save_objects(objects)
s.commit()

Here, a bulk insert will be made.

If you are using ipython in linux, then follow the steps:
!cd /directory_name/
You can try all the commands which work in you linux terminal.
!vi file_name.py

Just specify the exclamation(!) symbol before your linux commands.

It's because val is not null, but contains 'null' as a string.

Try to check with 'null'

if ('null' != val)

For an explanation of when and why this works, see the details below.

Individual TLD's can place their own rules & restrictions on domains names as they see fit, such as to accomodate local languages.

For example, according to the CIRA, Canada's .ca domain names are allowed:

• Letters a through z, and the following accented characters: é ë ê è â à æ ô œ ù û ü ç î ï ÿ. Note that Domain Names are not case sensitive. This means there will be no distinction made between upper case letters and lower case letters (A = a);

• The numbers 0123456789, and

• The hyphen character ("-) (although it cannot be used to start or end a Domain Name).

The maximum length is 63 characters, except each accented character reduces that limit by 4 characters.

(Source)

_{Incidentally, this allows for around 4 Quadragintillion domain name possibilities (not counting sub-domains) for dot-ca domains.}

1. del /s /q c:\where ever the file is\*
2. rmdir /s /q c:\where ever the file is\
3. mkdir c:\where ever the file is\

You can try the following query:

SELECT service_level, fixpack_num FROM TABLE
  (sysproc.env_get_inst_info())
  as INSTANCEINFO

It works on LUW, so I can't guarantee that it'll work on z/OS, but it's worth a shot.

From the Android Developers page,

onPause():

Called when the system is about to start resuming a previous activity. This is typically used to commit unsaved changes to persistent data, stop animations and other things that may be consuming CPU, etc. Implementations of this method must be very quick because the next activity will not be resumed until this method returns. Followed by either onResume() if the activity returns back to the front, or onStop() if it becomes invisible to the user.

onStop():

Called when the activity is no longer visible to the user, because another activity has been resumed and is covering this one. This may happen either because a new activity is being started, an existing one is being brought in front of this one, or this one is being destroyed. Followed by either onRestart() if this activity is coming back to interact with the user, or onDestroy() if this activity is going away.

Now suppose there are three Activities and you go from A to B, then onPause of A will be called now from B to C, then onPause of B and onStop of A will be called.

The paused Activity gets a Resume and Stopped gets Restarted.

When you call this.finish(), onPause-onStop-onDestroy will be called. The main thing to remember is: paused Activities get Stopped and a Stopped activity gets Destroyed whenever Android requires memory for other operations.

I hope it's clear enough.

I've also faced the problem of ordering of loaded scripts, which was solved through sequential loading of scripts. The loading is based on Rob W's answer.

function scriptFromFile(file) {
    var script = document.createElement("script");
    script.src = chrome.extension.getURL(file);
    return script;
}

function scriptFromSource(source) {
    var script = document.createElement("script");
    script.textContent = source;
    return script;
}

function inject(scripts) {
    if (scripts.length === 0)
        return;
    var otherScripts = scripts.slice(1);
    var script = scripts[0];
    var onload = function() {
        script.parentNode.removeChild(script);
        inject(otherScripts);
    };
    if (script.src != "") {
        script.onload = onload;
        document.head.appendChild(script);
    } else {
        document.head.appendChild(script);
        onload();
    }
}

The example of usage would be:

var formulaImageUrl = chrome.extension.getURL("formula.png");
var codeImageUrl = chrome.extension.getURL("code.png");

inject([
    scriptFromSource("var formulaImageUrl = '" + formulaImageUrl + "';"),
    scriptFromSource("var codeImageUrl = '" + codeImageUrl + "';"),
    scriptFromFile("EqEditor/eq_editor-lite-17.js"),
    scriptFromFile("EqEditor/eq_config.js"),
    scriptFromFile("highlight/highlight.pack.js"),
    scriptFromFile("injected.js")
]);

Actually, I'm kinda new to JS, so feel free to ping me to the better ways.

Resources from src/main/resources will be put onto the root of the classpath, so you'll need to get the resource as:

new BufferedReader(new InputStreamReader(getClass().getResourceAsStream("/config.txt")));

You can verify by looking at the JAR/WAR file produced by maven as you'll find config.txt in the root of your archive.

Make sure any XML file (or any file that would be interpreted as an XML file by visual studio) has a correct XML structure - that is, one root element (with any name, I have use rootElement in my example):

<?xml version="1.0"?> 
<rootElement>
 ...
</rootElement>

While @ajv-jsy's answer works most of the time, I had the same problem as @MarioVilas. If one of the strings to be compared contains a double quote ("), the variable expansion throws an error.

Example:

@echo off
SetLocal

set Lhs="
set Rhs="

if "%Lhs%" == "%Rhs%" echo Equal

Error:

echo was unexpected at this time.

Solution:

Enable delayed expansion and use ! instead of %.

@echo off
SetLocal EnableDelayedExpansion

set Lhs="
set Rhs="

if !Lhs! == !Rhs! echo Equal

:: Surrounding with double quotes also works but appears (is?) unnecessary.
if "!Lhs!" == "!Rhs!" echo Equal

I have not been able to break it so far using this technique. It works with empty strings and all the symbols I threw at it.

Test:

@echo off
SetLocal EnableDelayedExpansion

:: Test empty string
set Lhs=
set Rhs=
echo Lhs: !Lhs! & echo Rhs: !Rhs!
if !Lhs! == !Rhs! (echo Equal) else (echo Not Equal)
echo.

:: Test symbols
set Lhs= \ / : * ? " ' < > | %% ^^ ` ~ @ # $ [ ] & ( ) + - _ =
set Rhs= \ / : * ? " ' < > | %% ^^ ` ~ @ # $ [ ] & ( ) + - _ =
echo Lhs: !Lhs! & echo Rhs: !Rhs!
if !Lhs! == !Rhs! (echo Equal) else (echo Not Equal)
echo.

In XCode 7.3 I encountered the same question, I 've made the mistake because: Name in (info.plist -->Bundle identifier) is not the same as (target-->build settings -->packaging-->Product bundle identifier). Just make the same, that solved the problem.

All answers are great. Here is an example use case for multiple add address: The ability to add as many email you want on demand with a web form:

See it in action with jsfiddle here (except the php processor)

### Send unlimited email with a web form
# Form for continuously adding e-mails:
<button type="button" onclick="emailNext();">Click to Add Another Email.</button>
<div id="addEmail"></div>
<button type="submit">Send All Emails</button>
# Script function:
<script>
function emailNext() {
    var nextEmail, inside_where;
    nextEmail = document.createElement('input');
    nextEmail.type = 'text';
    nextEmail.name = 'emails[]';
    nextEmail.className = 'class_for_styling';
    nextEmail.style.display = 'block';
    nextEmail.placeholder  = 'Enter E-mail Here';
    inside_where = document.getElementById('addEmail');
    inside_where.appendChild(nextEmail);
    return false;
}
</script>
# PHP Data Processor:
<?php
// ...
// Add the rest of your $mailer here...
if ($_POST[emails]){
    foreach ($_POST[emails] AS $postEmail){
        if ($postEmail){$mailer->AddAddress($postEmail);}
    }
} 
?>

So what it does basically is to generate a new input text box on every click with the name "emails[]".

The [] added at the end makes it an array when posted.

Then we go through each element of the array with "foreach" on PHP side adding the:

    $mailer->AddAddress($postEmail);

JSL 1.7

The Oracle documentation mentions:

• unchecked: Unchecked warnings are identified by the string "unchecked".
• deprecation: A Java compiler must produce a deprecation warning when a type, method, field, or constructor whose declaration is annotated with the annotation @Deprecated is used (i.e. overridden, invoked, or referenced by name), unless: [...] The use is within an entity that is annotated to suppress the warning with the annotation @SuppressWarnings("deprecation"); or

It then explains that implementations can add and document their own:

Compiler vendors should document the warning names they support in conjunction with this annotation type. Vendors are encouraged to cooperate to ensure that the same names work across multiple compilers.

You can do it without setlocal, because of the setlocal command the variable won't survive an endlocal because it was created in setlocal. In this way the variable will be defined the right way.

To do that use this code:

set var1=A

set var2=B

set AB=hi

call set newvar=%%%var1%%var2%%%

echo %newvar% 

Note: You MUST use call before you set the variable or it won't work.

I hope that helps code. :) (I use)

function generateParameterForm(fieldName, promptText, valueType) {
    //<div class="form-group">
    //<label for="yyy" class="control-label">XXX</label>
    //<input type="text" class="form-control" id="yyy" name="yyy"/>
    //</div>

    // Add new div tag
    var form = $("<div/>").addClass("form-group");

    // Add label for prompt text
    var label = $("<label/>").attr("for", fieldName).addClass("control-label").text(promptText);

    // Add text field
    var input = $("<input/>").attr("type", "text").addClass("form-control").addClass(valueType).attr("id", fieldName).attr("name", fieldName);

    // lbl and inp => form
    $(form).append(label).append(input);

    return $(form);
}

Alternatively, create a figure() object using the figsize argument and then use add_subplot to add your subplots. E.g.

import matplotlib.pyplot as plt
import numpy as np

f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')

Benefits of this method are that the syntax is closer to calls of subplot() instead of subplots(). E.g. subplots doesn't seem to support using a GridSpec for controlling the spacing of the subplots, but both subplot() and add_subplot() do.

Use deepgrep and deepfind. On debian-based systems you can install them by:

sudo apt-get install strigi-utils

Both commands search for nested archives as well. In your case the command would look like:

find . -name "*.jar" | xargs -I {} deepfind {} | grep Hello.class

Short Answer:

Simple rule of thumb: Use POST to create, use PUT to update.

Long Answer:

POST:

• POST is used to send data to server.
• Useful when the resource's URL is unknown

PUT:

• PUT is used to transfer state to the server
• Useful when a resource's URL is known

Longer Answer:

To understand it we need to question why PUT was required, what were the problems PUT was trying to solve that POST couldn't.

From a REST architecture's point of view there is none that matters. We could have lived without PUT as well. But from a client developer's point of view it made his/her life a lot simpler.

Prior to PUT, clients couldn't directly know the URL that the server generated or if all it had generated any or whether the data to be sent to the server is already updated or not. PUT relieved the developer of all these headaches. PUT is idempotent, PUT handles race conditions, and PUT lets the client choose the URL.

If you want to call other api routes in the future and keep your token in the store then try using redux middleware.

The middleware could listen for the an api action and dispatch api requests through axios accordingly.

Here is a very basic example:

actions/api.js

export const CALL_API = 'CALL_API';

function onSuccess(payload) {
  return {
    type: 'SUCCESS',
    payload
  };
}

function onError(payload) {
  return {
    type: 'ERROR',
    payload,
    error: true
  };
}

export function apiLogin(credentials) {
  return {
    onSuccess,
    onError,
    type: CALL_API,
    params: { ...credentials },
    method: 'post',
    url: 'login'
  };
}

middleware/api.js

import axios from 'axios';
import { CALL_API } from '../actions/api';

export default ({ getState, dispatch }) => next => async action => {
  // Ignore anything that's not calling the api
  if (action.type !== CALL_API) {
    return next(action);
  }

  // Grab the token from state
  const { token } = getState().session;

  // Format the request and attach the token.
  const { method, onSuccess, onError, params, url } = action;

  const defaultOptions = {
    headers: {
      Authorization: token ? `Token ${token}` : '',
    }
  };

  const options = {
    ...defaultOptions,
    ...params
  };

  try {
    const response = await axios[method](url, options);
    dispatch(onSuccess(response.data));
  } catch (error) {
    dispatch(onError(error.data));
  }

  return next(action);
};

<script type="text/javascript">
      function idleTimer() {
    var t;
    //window.onload = resetTimer;
    window.onmousemove = resetTimer; // catches mouse movements
    window.onmousedown = resetTimer; // catches mouse movements
    window.onclick = resetTimer;     // catches mouse clicks
    window.onscroll = resetTimer;    // catches scrolling
    window.onkeypress = resetTimer;  //catches keyboard actions

    function logout() {
        window.location.href = 'logout.php';  //Adapt to actual logout script
    }

   function reload() {
          window.location = self.location.href;  //Reloads the current page
   }

   function resetTimer() {
        clearTimeout(t);
        t = setTimeout(logout, 1800000);  // time is in milliseconds (1000 is 1 second)
        t= setTimeout(reload, 300000);  // time is in milliseconds (1000 is 1 second)
    }
}
idleTimer();

On ubuntu

 sudo apt-get install librxtx-java then 

add RXTX jars to the project which are in

 usr/share/java

I have also tried that error , I got it right by just adding /hello/any name because it is path that there must be an hello/name

example : instead of just putting http://localhost/app_dev.php

put it like this way http://localhost/name_of_your_project/web/app_dev.php/hello/ai

it will display Hello Ai . I hope I answer your question.

I know its stupid but in my case i was outside of my project folder i didn't have spark file.

In internet explorer, if the new url is from the same domain as the current url, the window will be open without an address bar. Otherwise, it will cause an address bar to appear. One workaround is to open a page from the same domain and then redirect from that page.

Ensure you have an index on your firstname and lastname columns and go with 1. This really won't have much of a performance impact at all.

EDIT: After @Dems comment regarding spamming the plan cache ,a better solution might be to create a computed column on the existing table (or a separate view) which contained a concatenated Firstname + Lastname value, thus allowing you to execute a query such as

SELECT City 
FROM User 
WHERE Fullname in (@fullnames)

where @fullnames looks a bit like "'JonDoe', 'JaneDoe'" etc

Bundle:- A mapping from String values to various Parcelable types.

Bundle is generally used for passing data between various activities of android.

when we call onPause() then onStop() and then in reverse order onStop() to onPause().

The saved data that the system uses to restore the previous state is called the "instance state" and is a collection of key-value pairs stored in a Bundle object.

Here is a screenshot:

????????

You've got to override your Canvas's paint(Graphics g) method and perform your drawing there. See the paint() documentation.

As it states, the default operation is to clear the canvas, so your call to the canvas' graphics object doesn't perform as you would expect.

Solved, just use select method for the dataframe to select columns:

 val df=spark.read.csv("C:\\Users\\Ahmed\\Desktop\\cabs_trajectories\\cabs_trajectories\\green\\2014\\green_tripdata_2014-09.csv")

val df1=df.select("_c0")

this would subset the first column of the dataframe

A small static custom method in a Util class would help:

 public static int getIndex(Set<? extends Object> set, Object value) {
   int result = 0;
   for (Object entry:set) {
     if (entry.equals(value)) return result;
     result++;
   }
   return -1;
 }

If you need/want one class that is a Set and offers a getIndex() method, I strongly suggest to implement a new Set and use the decorator pattern:

 public class IndexAwareSet<T> implements Set {
   private Set<T> set;
   public IndexAwareSet(Set<T> set) {
     this.set = set;
   }

   // ... implement all methods from Set and delegate to the internal Set

   public int getIndex(T entry) {
     int result = 0;
     for (T entry:set) {
       if (entry.equals(value)) return result;
       result++;
     }
     return -1;
   }
 }

Just wanted to share with you:
I happened to get this error after changing Digital Ocean machine (IP address). Apparently Gmail recognized it as a hacking attack. After following their directions, and approving the new IP address the code is back and running.

Working from J.F. Sebastian's answer, and several other sources, I've put together a simple subprocess manager. It provides the request non-blocking reading, as well as running several processes in parallel. It doesn't use any OS-specific call (that I'm aware) and thus should work anywhere.

It's available from pypi, so just pip install shelljob. Refer to the project page for examples and full docs.

If you have a module with a class you want to import, you can do it like this.

module = __import__(filename)
instance = module.MyClass()

If you do not know what the class is named, you can iterate through the classes available from a module.

import inspect
module = __import__(filename)
for c in module.__dict__.values():
    if inspect.isclass(c):
        # You may need do some additional checking to ensure 
        # it's the class you want
        instance = c()

The following command will delete images older than 48 hours.

$ docker image prune --all --filter until=48h

In swift 3.0 If you want to go any particular Cell of tableview Change cell index Value like change "self.yourArr.count" value .

self.yourTable.reloadData()
self.scrollToBottom() 
func scrollToBottom(){
    DispatchQueue.global(qos: .background).async {
        let indexPath = IndexPath(row: self.yourArr.count-1, section: 0)
        self.tblComment.scrollToRow(at: indexPath, at: .bottom, animated: true)
    }
}

sometimes unchecked means other values, for instance checked could mean yes unchecked no or 0,1 etc it depends on the meaning you want to give.. so could be another state besides "unchecked means it's not in the querystring at all"

"It would make it a lot easier to store information in DB. Because then the number of fields from Serialize would equal the number of fields in table. Now I have to contrll which ones are missing", youre right this is my problem too... so it appears i have to check for this nonexisting value....

but maybe this could be a solution? http://tdanemar.wordpress.com/2010/08/24/jquery-serialize-method-and-checkboxes/

char* charP = createStr();

Would be correct if your function was correct. Unfortunately you are returning a pointer to a local variable in the function which means that it is a pointer to undefined data as soon as the function returns. You need to use heap allocation like malloc for the string in your function in order for the pointer you return to have any meaning. Then you need to remember to free it later.

From docs and example it is not clear that classpath manipulation is not allowed.

<configuration>
 <compilerArgs>
  <arg>classpath=${basedir}/lib/bad.jar</arg>
 </compilerArgs>
</configuration>

But see Java docs (also https://www.cis.upenn.edu/~bcpierce/courses/629/jdkdocs/tooldocs/solaris/javac.html)

-classpath path Specifies the path javac uses to look up classes needed to run javac or being referenced by other classes you are compiling. Overrides the default or the CLASSPATH environment variable if it is set.

Maybe it is possible to get current classpath and extend it,
see in maven, how output the classpath being used?

Try JetBrains dotPeek. It's free.

This is supposedly because you trying to make cross-domain request, or something that is clarified as it. You could try adding header('Access-Control-Allow-Origin: *'); to the requested file.

Also, such problem is sometimes occurs on server-sent events implementation in case of using event-source or XHR polling in IE 8-10 (which confused me first time).

Try WebClient.DownloadFileAsync(). You can call CancelAsync() by timer with your own timeout.

Doing sys.path.append('my-path-to-module-folder') will work, but to avoid having to do this in IPython every time you want to use the module, you can add export PYTHONPATH="my-path-to-module-folder:$PYTHONPATH" to your ~/.bash_profile file.

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');
    }

for MaterialButton, add below properties, it will work perfectly

<android.support.design.button.MaterialButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:insetTop="0dp"
    android:insetBottom="0dp"/>

Here's a simple function. It generates a data frame and automatically uses the names of the vectors as values for the first column.

myfunc <- function(a, b, names = NULL) {
  setNames(data.frame(c(rep(deparse(substitute(a)), length(a)), 
                        rep(deparse(substitute(b)), length(b))), c(a, b)), names)
}

An example:

x <-c(1,2,3)
y <-c(100,200,300)
x_name <- "cond"
y_name <- "rating"

myfunc(x, y, c(x_name, y_name))

  cond rating
1    x      1
2    x      2
3    x      3
4    y    100
5    y    200
6    y    300

Use:

str.getBytes("UTF-16LE");

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

Does this really make sense?
There is no "first" record in a relational database, you can only delete one random record.

I suggest making site.com redirect to www.site.com for both consistency and for avoiding issues like this.

Also, consider using a cross-browser solution like PersistJS that can use each browser native storage.

Cross-browser @media (width) and @media (height) values 

const vw = Math.max(document.documentElement.clientWidth || 0, window.innerWidth || 0)
const vh = Math.max(document.documentElement.clientHeight || 0, window.innerHeight || 0)

window.innerWidth and window.innerHeight

• gets CSS viewport @media (width) and @media (height) which include scrollbars
• initial-scale and zoom variations may cause mobile values to wrongly scale down to what PPK calls the visual viewport and be smaller than the @media values
• zoom may cause values to be 1px off due to native rounding
• undefined in IE8-

document.documentElement.clientWidth and .clientHeight

• equals CSS viewport width minus scrollbar width
• matches @media (width) and @media (height) when there is no scrollbar
• same as jQuery(window).width() which jQuery calls the browser viewport
• available cross-browser
• inaccurate if doctype is missing

Resources

• Live outputs for various dimensions
• verge uses cross-browser viewport techniques
• actual uses matchMedia to obtain precise dimensions in any unit

You need to run it with -d flag to leave it running as daemon in the background.

docker run -d -it ubuntu bash

In ES6/ES2015 you can use string literal syntax called template literals. Template strings use backtick character instead of single quote ' or double quote marks ". They also preserve new line and tab

const roleName = 'test1';_x000D_
const role_ID = 'test2';_x000D_
const modal_ID = 'test3';_x000D_
const related = 'test4';_x000D_
        _x000D_
console.log(`_x000D_
  roleName = ${roleName}_x000D_
  role_ID = ${role_ID}_x000D_
  modal_ID = ${modal_ID}_x000D_
  related = ${related}_x000D_
`);

If someone ends up here from google, looking to convert a single figure to a .pdf (that was what I was looking for):

import matplotlib.pyplot as plt

f = plt.figure()
plt.plot(range(10), range(10), "o")
plt.show()

f.savefig("foo.pdf", bbox_inches='tight')

You can rollback your migration by using rake db:rollback with different options. The syntax will be different according to your requirements.

If you want to rollback just the last migration, then you can use either

rake db:rollback

or

rake db:rollback STEP=1

If you want rollback number of migrations at once, then you simply pass an argument:

rake db:rollback STEP=n

where n is number of migrations to rollback, counting from latest migration.

If you want to rollback to a specific migration, then you should pass the version of the migration in the following:

rake db:migrate:down VERSION=xxxxx

where xxxxx is the version number of the migration.

You can try using this way :

sentence ["Robert"] = "Roger"

Then the sentence will become :

sentence = "My name is Roger" # Robert is replaced with Roger

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

I'm not sure I really understood what you want to do, but the suggested way to communicate between fragments is to use callbacks with the Activity, never directly between fragments. See here http://developer.android.com/training/basics/fragments/communicating.html

Im using Asp.Net Core 2.2 with MVC and Razor cshtml My JQuery is referenced in a layout page I needed to add the following to my view.cshtml:

@section Scripts {
$script-here
}

You can check if the row exists, and then INSERT or UPDATE, but this guarantees you will be performing two SQL operations instead of one:

1. check if row exists
2. insert or update row

A better solution is to always UPDATE first, and if no rows were updated, then do an INSERT, like so:

update table1 
set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
where id = 'val1'

if @@ROWCOUNT = 0
  insert into table1(id, name, itemname, itemcatName, itemQty)
  values('val1', 'val2', 'val3', 'val4', 'val5')

This will either take one SQL operations, or two SQL operations, depending on whether the row already exists.

But if performance is really an issue, then you need to figure out if the operations are more likely to be INSERT's or UPDATE's. If UPDATE's are more common, do the above. If INSERT's are more common, you can do that in reverse, but you have to add error handling.

BEGIN TRY
  insert into table1(id, name, itemname, itemcatName, itemQty)
  values('val1', 'val2', 'val3', 'val4', 'val5')
END TRY
BEGIN CATCH
  update table1 
  set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
  where id = 'val1'
END CATCH

To be really certain if you need to do an UPDATE or INSERT, you have to do two operations within a single TRANSACTION. Theoretically, right after the first UPDATE or INSERT (or even the EXISTS check), but before the next INSERT/UPDATE statement, the database could have changed, causing the second statement to fail anyway. This is exceedingly rare, and the overhead for transactions may not be worth it.

Alternately, you can use a single SQL operation called MERGE to perform either an INSERT or an UPDATE, but that's also probably overkill for this one-row operation.

Consider reading about SQL transaction statements, race conditions, SQL MERGE statement.

You can add your own css property for button size as follows:

.btn {
    min-width: 250px;
}

Be aware to use constant HTTPS or HTTP for all requests. I had the same error msg: "No 'Access-Control-Allow-Origin' header is present on the requested resource."

I recently hit the same error. Some digging brought up this: http://support.microsoft.com/kb/815645

Basically, if you have spaces in the path of the .lib, that's bad. Don't know if that's what's happening for you, but seems reasonably possible.

The fix is either 1) put the lib reference in "quotes", or 2) add the lib's path to your Library Directories (Configuration Properties >> VC++ Directories).

There are multiple ways to achieve this. I can explain you in brief about the 4 types which we use in our daily programming life cycle.

Please go through the below points.

1 Query String.

FirstForm.aspx.cs

Response.Redirect("SecondForm.aspx?Parameter=" + TextBox1.Text);

SecondForm.aspx.cs

TextBox1.Text = Request.QueryString["Parameter"].ToString();

This is the most reliable way when you are passing integer kind of value or other short parameters. More advance in this method if you are using any special characters in the value while passing it through query string, you must encode the value before passing it to next page. So our code snippet of will be something like this:

FirstForm.aspx.cs

Response.Redirect("SecondForm.aspx?Parameter=" + Server.UrlEncode(TextBox1.Text));

SecondForm.aspx.cs

TextBox1.Text = Server.UrlDecode(Request.QueryString["Parameter"].ToString());

URL Encoding

1. Server.URLEncode
   
2. HttpServerUtility.UrlDecode

2. Passing value through context object

Passing value through context object is another widely used method.

FirstForm.aspx.cs

TextBox1.Text = this.Context.Items["Parameter"].ToString();

SecondForm.aspx.cs

this.Context.Items["Parameter"] = TextBox1.Text;
Server.Transfer("SecondForm.aspx", true);

Note that we are navigating to another page using Server.Transfer instead of Response.Redirect.Some of us also use Session object to pass values. In that method, value is store in Session object and then later pulled out from Session object in Second page.

3. Posting form to another page instead of PostBack

Third method of passing value by posting page to another form. Here is the example of that:

FirstForm.aspx.cs

private void Page_Load(object sender, System.EventArgs e)
{
   buttonSubmit.Attributes.Add("onclick", "return PostPage();");
}

And we create a javascript function to post the form.

SecondForm.aspx.cs

function PostPage()
{
   document.Form1.action = "SecondForm.aspx";
   document.Form1.method = "POST";
   document.Form1.submit();
}
TextBox1.Text = Request.Form["TextBox1"].ToString();

Here we are posting the form to another page instead of itself. You might get viewstate invalid or error in second page using this method. To handle this error is to put EnableViewStateMac=false

4. Another method is by adding PostBackURL property of control for cross page post back

In ASP.NET 2.0, Microsoft has solved this problem by adding PostBackURL property of control for cross page post back. Implementation is a matter of setting one property of control and you are done.

FirstForm.aspx.cs

<asp:Button id=buttonPassValue style=”Z-INDEX: 102" runat=”server” Text=”Button”         PostBackUrl=”~/SecondForm.aspx”></asp:Button>

SecondForm.aspx.cs

TextBox1.Text = Request.Form["TextBox1"].ToString();

In above example, we are assigning PostBackUrl property of the button we can determine the page to which it will post instead of itself. In next page, we can access all controls of the previous page using Request object.

You can also use PreviousPage class to access controls of previous page instead of using classic Request object.

SecondForm.aspx

TextBox textBoxTemp = (TextBox) PreviousPage.FindControl(“TextBox1");
TextBox1.Text = textBoxTemp.Text;

As you have noticed, this is also a simple and clean implementation of passing value between pages.

HAPPY CODING!

something like:

    $('#doc').click(function(e){
       e.preventDefault()
       e.stopImmediatePropagation() //charles ma is right about that, but stopPropagation isn't also needed
});

should do the job you could also bind more mouse events with replacing for: edit: add this in the feezing part

    $('#doc').bind('click mousedown dblclick',function(e){
       e.preventDefault()
       e.stopImmediatePropagation()
});

and this in the unfreezing:

  $('#doc').unbind();

As mentioned in the other answers, previous versions of openssl used a weak key derivation function to derive an AES encryption key from the password. However, openssl v1.1.1 supports a stronger key derivation function, where the key is derived from the password using pbkdf2 with a randomly generated salt, and multiple iterations of sha256 hashing (10,000 by default).

To encrypt a file:

 openssl aes-256-cbc -e -salt -pbkdf2 -iter 10000 -in plaintextfilename -out encryptedfilename

To decrypt a file:

  openssl aes-256-cbc -d -salt -pbkdf2 -iter 10000 -in encryptedfilename -out plaintextfilename

Check file permissions.

I had exactly the same error on a Linux machine with the wrong permissions set.

chmod 755 myfile.pl

solved the problem.

Big thanks to the contributors to the answers here, it pointed me in the right direction.

For the Bootstrap4 users out there, this worked for me. Sets the a link (tap target) to correct size to pass the Lighthouse Site Audit on mobiles.

    <span class="small">
         <a class="d-inline position-relative p-3 m-n3" style="z-index: 1;" href="/AdvancedSearch" title="Advanced Site Search using extra optional filters">Advanced Site Search</a>
    </span>

A very easy kind of event you can wait for is the ManualResetEvent, and even better, the ManualResetEventSlim.

They have a WaitOne() method that does exactly that. You can wait forever, or set a timeout, or a "cancellation token" which is a way for you to decide to stop waiting for the event (if you want to cancel your work, or your app is asked to exit).

You fire them calling Set().

Here is the doc.

try to use an asterisk before list's name with print statement:

names = ["Sam", "Peter", "James", "Julian", "Ann"]  
print(*names)

output:

Sam Peter James Julian Ann

you want to use include_once() or require_once(). The other option would be to create an additional file with all your class includes in the correct order so they don't need to call includes themselves:

"classes.php"

include 'database.php';
include 'parent.php';
include 'child1.php';
include 'child2.php';

Then you just need:

require_once('classes.php');

Here the code where you can delete file/image from folder.

var fs = require('fs'); 
Gallery.findById({ _id: req.params.id},function(err,data){ 
    if (err) throw err;
    fs.unlink('public/gallery/'+data.image_name);
 });

If you want to pass the type, than the equivalent in Java would be

java.lang.Class

If you want to use a weakly typed method, then you would simply use

java.lang.Object

and the corresponding operator

instanceof

e.g.

private void foo(Object o) {

  if(o instanceof String) {

  }

}//foo

However, in Java there are primitive types, which are not classes (i.e. int from your example), so you need to be careful.

The real question is what you actually want to achieve here, otherwise it is difficult to answer:

Or is there a better way?

In two way ssl the client asks for servers digital certificate and server ask for the same from the client. It is more secured as it is both ways, although its bit slow. Generally we dont follow it as the server doesnt care about the identity of the client, but a client needs to make sure about the integrity of server it is connecting to.

You can do that I believe. It needs root permission. If you want to know where your apk files are stored, open a emulator and then go to

DDMS>File Explorer-> you can see a directory by name "data" -> Click on it and you will see a "app" folder.

Your apks are stored there. In fact just copying a apk directly to the folder works for me with emulators.

This could be a permissions issue.

I had the same issue recently. As a test, I created a simple hello.html page. When I tried loading it, I got an error message regarding permissions. Once I fixed the permissions issue in the root web folder, both the html page and the MVC rendering issues were resolved.

Here's another way of attaching the event based on W3C DOM Level 2 Events Specification:

  transport_select.addEventListener(
     'change',
     function() { toggleSelect(this.id); },
     false
  );

iif has always been available in VB, even in VB6.

Dim foo as String = iif(bar = buz, cat, dog)

It is not a true operator, as such, but a function in the Microsoft.VisualBasic namespace.

You maybe wanted to do the following:

foreach($user->data as $mydata)

    {
         echo $mydata->name . "\n";
         foreach($mydata->values as $values)
         {
              echo $values->value . "\n";
         }
    }        

In case, for whatever reason, you are doing a rebase from a folder that's being sync'd by a cloud service (dropbox, drive, onedrive, etc), you should pause or turn off syncing as it will interfere with permissions during the rebase.

Just for completion: All the answers above are going for a shallow copy - keeping the reference of the original objects. I you want a deep copy, your (reference-) class in the list have to implement a clone / copy method, which provides a deep copy of a single object. Then you can use:

newList.addAll(oldList.stream().map(s->s.clone()).collect(Collectors.toList()));

The original DateTime field : [_Date_Time]

The converted to Shortdate : 'Short_Date'

CONVERT(date, [_Date_Time]) AS 'Short_Date'
