Note: I've only tested this in Chrome.

it adds a prototype function to the XMLHttpRequest .. XHR2,

in XHR 1 you probably just need to replace this.response with this.responseText

Object.defineProperty(XMLHttpRequest.prototype,'responseJSON',{value:function(){
 return JSON.parse(this.response);
},writable:false,enumerable:false});

to return the json in xhr2

xhr.onload=function(){
 console.log(this.responseJSON());
}

EDIT

If you plan to use XHR with arraybuffer or other response types then you have to check if the response is a string.

in any case you have to add more checks e.g. if it's not able to parse the json.

Object.defineProperty(XMLHttpRequest.prototype,'responseJSON',{value:function(){
 return (typeof this.response==='string'?JSON.parse(this.response):this.response);
},writable:false,enumerable:false});

You probably want this (to make it like a normal CSS background-image declaration):

$('myObject').css('background-image', 'url(' + imageUrl + ')');

Properties can return anything they want to, but it's going to need to return the correct type.

private decimal _amount;

public string FormattedAmount
{
    get { return string.Format("{0:C}", _amount); }
}

Question was asked... what if it was a nullable decimal.

private decimal? _amount;

public string FormattedAmount
{
    get
    {
         return _amount == null ? "null" : string.Format("{0:C}", _amount.Value);
    }
}  

private void readFile() throws Exception {
      AsynchronousFileChannel input=AsynchronousFileChannel.open(Paths.get("E:/dicom_server_storage/abc.txt"),StandardOpenOption.READ);
      ByteBuffer buffer=ByteBuffer.allocate(1024);
      input.read(buffer,0,null,new CompletionHandler<Integer,Void>(){
        @Override public void completed(    Integer result,    Void attachment){
          System.out.println("Done reading the file.");
        }
        @Override public void failed(    Throwable exc,    Void attachment){
          System.err.println("An error occured:" + exc.getMessage());
        }
      }
    );
      System.out.println("This thread keeps on running");
      Thread.sleep(100);
    }

My solution looks much like Tims but also works in case of non-worksheet sheets - charts

Public Function SheetExists(strSheetName As String, Optional wbWorkbook As Workbook) As Boolean
    If wbWorkbook Is Nothing Then Set wbWorkbook = ActiveWorkbook 'or ThisWorkbook - whichever appropriate
    Dim obj As Object
    On Error GoTo HandleError
    Set obj = wbWorkbook.Sheets(strSheetName)
    SheetExists = True
    Exit Function
HandleError:
    SheetExists = False
End Function

.

public long millis() {
  return (long.MaxValue + DateTime.Now.ToBinary()) / 10000;
}

If you want microseconds, just change 10000 to 10, and if you want the 10th of micro, delete / 10000.

If you don't mind using jQuery you can use the code bellow:

    <script>
     $(document).ready(function(){
           $("#department").val("${requestScope.selectedDepartment}").attr('selected', 'selected');
     });
     </script>


    <select id="department" name="department">
      <c:forEach var="item" items="${dept}">
        <option value="${item.key}">${item.value}</option>
      </c:forEach>
    </select>

In the your Servlet add the following:

        request.setAttribute("selectedDepartment", YOUR_SELECTED_DEPARTMENT );

Your controller method should be like this:

@RequestMapping(value = " /<your mapping>/{id}", method=RequestMethod.GET)
public String listNotes(@PathVariable("id")int id,Model model) {
    Person person = personService.getCurrentlyAuthenticatedUser();
    int id = 2323;  // Currently passing static values for testing
    model.addAttribute("person", new Person());
    model.addAttribute("listPersons", this.personService.listPersons());
    model.addAttribute("listNotes",this.notesService.listNotesBySectionId(id,person));
    return "note";
}

Use the id in your code, call the controller method from your JSP as:

/{your mapping}/{your id}

UPDATE:

Change your jsp code to:

<c:forEach items="${listNotes}" var="notices" varStatus="status">
    <tr>
        <td>${notices.noticesid}</td>
        <td>${notices.notetext}</td>
        <td>${notices.notetag}</td>
        <td>${notices.notecolor}</td>
        <td>${notices.sectionid}</td>
        <td>${notices.canvasid}</td>
        <td>${notices.canvasnName}</td>
        <td>${notices.personid}</td>
        <td><a href="<c:url value='/editnote/${listNotes[status.index].noticesid}' />" >Edit</a></td>
        <td><a href="<c:url value='/removenote/${listNotes[status.index].noticesid}' />" >Delete</a></td>
    </tr>
</c:forEach>

If you don’t like changing files in such a way then alternative way would be to use this package.

https://pub.dev/packages/rename

rename --bundleId com.newpackage.appname
pub global run rename --appname "Your New App Name"

Using this, you simply run these 2 commands in your terminal and your app name and identifiers will be changed.pub global run

PHP is a normal sripting language similar to bash or python or perl. So a script with shebang works, at least on linux.

Example PHP file:

#!/usr/bin/env php

<?php

echo("Hello World!\n")

?>

How to run it:

$ chmod 755 hello.php  # do this only once
$ ./hello.php

I found this question after coming across something similar in my work, yesterday. My solution in the end was a hybrid of some of the approaches above:

function is_JSON($string) {

  return (is_null(json_decode($string, TRUE))) ? FALSE : TRUE;

}

I had to change /etc/profile.d/java_env.sh to point to the new path and then logout/login.

Use mongod --shutdown

According to the official doc : manage-mongodb-processes/

:D

Another variation on the already proposed answers without jQuery.

Object.values(document.getElementById('mySelect').options).forEach(option => alert(option))

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

As far as I read manual pages, scanf says that 'l' length modifier indicates (in case of floating points) that the argument is of type double rather than of type float, so you can have 'lf, le, lg'.

As for printing, officially, the manual says that 'l' applies only to integer types. So it might be not supported on some systems or by some standards. For instance, I get the following error message when compiling with gcc -Wall -Wextra -pedantic

a.c:6:1: warning: ISO C90 does not support the ‘%lf’ gnu_printf format [-Wformat=]

So you may want to doublecheck if your standard supports the syntax.

To conclude, I would say that you read with '%lf' and you print with '%f'.

Adding the link as an Answer to draw more attention to Aaron Lavers' comment below the first answer.

This works like a charm - http://clipboardjs.com. Just add the clipboard.js or min file. While initiating, use the class which has the html component to be clicked and just pass the id of the component with the content to be copied, to the click element.

This one is violent use with caution :

pkill -9 -e -f processname 

If your process name is "sh" it will also kill "bash"

When dealing with a hash {}, use both the key and value to the block inside the ||.

details.map {|key,item|"" == item}

=>[false, false, true, false, false]

HTML

<a href="demoLink" id="myLink"> myLink </a>
<button onclick="fireLink(event)"> Call My Link </button>

JS

// click event listener of the link element --------------  
document.getElementById('myLink').addEventListener("click", callLink);
function callLink(e) {
    // code to fire
}

// function invoked by the button element ----------------
function fireLink(event) {                   
    document.getElementById('myLink').click();      // script calls the "click" event of the link element 
}

This is an excerpt from method of mine, which converts a DataTable (the dt variable) into an array and then writes the array into a Range on a worksheet (wsh var). You can also change the topRow variable to whatever row you want the array of strings to be placed at.

object[,] arr = new object[dt.Rows.Count, dt.Columns.Count];
for (int r = 0; r < dt.Rows.Count; r++)
{
    DataRow dr = dt.Rows[r];
    for (int c = 0; c < dt.Columns.Count; c++)
    {
        arr[r, c] = dr[c];
    }
}
Excel.Range c1 = (Excel.Range)wsh.Cells[topRow, 1];
Excel.Range c2 = (Excel.Range)wsh.Cells[topRow + dt.Rows.Count - 1, dt.Columns.Count];
Excel.Range range = wsh.get_Range(c1, c2);
range.Value = arr;

Of course you do not need to use an intermediate DataTable like I did, the code excerpt is just to demonstrate how an array can be written to worksheet in single call.

Using CTEs you can do it this way

DECLARE @Table TABLE(
        PersonID INT,
        Initials VARCHAR(20),
        ParentID INT
)

INSERT INTO @Table SELECT     1,'CJ',NULL
INSERT INTO @Table SELECT     2,'EB',1
INSERT INTO @Table SELECT     3,'MB',1
INSERT INTO @Table SELECT     4,'SW',2
INSERT INTO @Table SELECT     5,'YT',NULL
INSERT INTO @Table SELECT     6,'IS',5

DECLARE @PersonID INT

SELECT @PersonID = 1

;WITH Selects AS (
        SELECT *
        FROM    @Table
        WHERE   PersonID = @PersonID
        UNION ALL
        SELECT  t.*
        FROM    @Table t INNER JOIN
                Selects s ON t.ParentID = s.PersonID
)
SELECT  *
FROm    Selects

Works only in Google Chrome with self.close();. Tested in v48.

window.close() won't do what you want as the documentation for it clearly states that scripts may close only the windows that were opened by it.

As the above people stated, select PostGIS_full_version(); will answer your question. On my machine, where I'm running PostGIS 2.0 from trunk, I get the following output:

postgres=# select PostGIS_full_version();
postgis_full_version                                                                  
-------------------------------------------------------------------------------------------------------------------------------------------------------
POSTGIS="2.0.0alpha4SVN" GEOS="3.3.2-CAPI-1.7.2" PROJ="Rel. 4.7.1, 23 September 2009" GDAL="GDAL 1.8.1, released 2011/07/09" LIBXML="2.7.3" USE_STATS
(1 row)

You do need to care about the versions of PROJ and GEOS that are included if you didn't install an all-inclusive package - in particular, there's some brokenness in GEOS prior to 3.3.2 (as noted in the postgis 2.0 manual) in dealing with geometry validity.

I'm assuming you are having at least OSX 10.7, so go ahead into the applications folder (Click on Finder icon > On the Sidebar, you'll find "Applications", click on it ), delete the "Xcode" icon. That will remove Xcode from your system completely. Restart your mac.

Now go to https://developer.apple.com/download/more/ and download an older version of Xcode, as needed and install. You need an Apple ID to login to that portal.

JAXB is simple to use and is included in Java 6 SE. With JAXB, or other XML data binding such as Simple, you don't have to handle the XML yourself, most of the work is done by the library. The basic usage is to add annotation to your existing POJO. These annotation are then used to generate an XML Schema for you data and also when reading/writing your data from/to a file.

If you need input from termial, try this

lc=`echo -n "xxx_${yyy}_iOS" |  base64`

-n option will not input "\n" character to base64 command.

I think we can do this with one line simple command

for i in `grep -rl eth0 . 2> /dev/null`; do sed -i ‘s/eth0/eth1/’ $i; done

Refer to this page.

You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.

The ISO-8601 format for a DATETIME when using only the date is: YYYYMMDD (no dashes or antyhing!)

For a DATETIME with the time portion, it's YYYY-MM-DDTHH:MM:SS (with dashes, and a T in the middle to separate date and time portions).

If you want to convert a string to a DATE for SQL Server 2008 or newer, you can use YYYY-MM-DD (with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.

So in your case, you should try:

declare @a datetime
declare @b datetime 

set @a = '2012-04-06T12:23:45'   -- 6th of April, 2012
set @b = '2012-08-06T21:10:12'   -- 6th of August, 2012

exec LogProcedure 'AccountLog', N'test', @a, @b

Furthermore - your stored proc has problem, since you're concatenating together datetime and string into a string, but you're not converting the datetime to string first, and also, you're forgetting the close quotes in your statement after both dates.

So change this line here to this:

IF @DateFirst <> '' and @DateLast <> ''
   SET @FinalSQL  = @FinalSQL + '  OR CONVERT(Date, DateLog) >= ''' + 
                    CONVERT(VARCHAR(50), @DateFirst, 126) +   -- convert @DateFirst to string for concatenation!
                    ''' AND CONVERT(Date, DateLog) <=''' +  -- you need closing quotes after @DateFirst!
                    CONVERT(VARCHAR(50), @DateLast, 126) + ''''      -- convert @DateLast to string and also: closing tags after that missing!

With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.

     data-ng-click="featureClass=!featureClass"

Analogous to jQuery's toggleClass method, this is a way to toggle the active class on/off when the element is clicked.

Just start emulator by command line as follow:

Just in case it helps someone, here's what caused this error for me: I needed a procedure to return json but I left out the for json path:

set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite 
            from CS_GEO G (nolock) 
                join @allids a on g.ID = a.[value] 
            where g.Worksite = @worksite)

When I tried to save the stored procedure, it threw the error. I fixed it by adding for json path to the code at the end of the procedure:

set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite 
            from CS_GEO G (nolock) 
                join @allids a on g.ID = a.[value] 
            where g.Worksite = @worksite for json path)

It looks like you have a typo on your array, it should read:

int my_array[3][3] = {...

You don't have the _ or the {.

Also my_array[3][3] is an invalid location. Since computers begin counting at 0, you are accessing position 4. (Arrays are weird like that).

If you want just the last element:

printf("%d\n", my_array[2][2]);

If you want the entire array:

for(int i = 0; i < my_array.length; i++) {
  for(int j = 0; j < my_array[i].length; j++)
    printf("%d ", my_array[i][j]);
  printf("\n");
}

HTML : Pass the whole body inside on click

div class="calculate" id="calculate">
            <div class="button" id="button" onclick="myCode(this.body)"> CALCULATE ! </div>
        </div>

Then write the JavaScript code inside the function "myCode()"

function myCode()
{
    var bill = document.getElementById("currency").value ;

    var people_count = document.getElementById("number1").value;
    var select_value = document.getElementById("select").value;

    var calculate = document.getElementById("calculate");

    calculate.addEventListener("click" ,function()
    {
        console.log(bill);
        console.log(people_count);
        console.log(select_value);
    });
}

you will get your values I am using visual studio code editor

<?php
$first = reset($arr_nav); // Get the first element
$last  = end($arr_nav);   // Get the last element
// Ensure that we have a first element and that it's an array
if(is_array($first)) { 
   $first['class'] = 'first';
}
// Ensure we have a last element and that it differs from the first
if(is_array($last) && $last !== $first) {
   $last['class'] = 'last';
}

Now you could just echo the class inside you html-generator. Would probably need some kind of check to ensure that the class is set, or provide a default empty class to the array.

As per Google recent announcement, usage of the Google Maps APIs now requires a key. If you are using the Google Maps API on localhost or your domain was not active prior to June 22nd, 2016, it will require a key going forward. Please see the Google Maps APIs documentation to get a key and add it to your application.

From the other answers, the problem is that you're templating a typedef. The only "way" to do this is to use a templated class; ie, basic template metaprogramming.

template<class T> class vector_Typedefs {
    /*typedef*/ struct array { //The typedef isn't necessary
        size_t x; 
        T *ary; 
    }; 

    //Any other templated typedefs you need. Think of the templated class like something
    // between a function and namespace.
}

//An advantage is:
template<> class vector_Typedefs<bool>
{
    struct array {
        //Special behavior for the binary array
    }
}

A more general approach:

if ( ($("body").hasClass("homepage") || $("body").hasClass("contact")) && (theLanguage == 'en-gb') )   {

       // Do something

}

did you try 'localhost/phpmyadmin' ? (notice the lowercase)

PHPMyAdmin tends to have inconsistent directory names across its versions/distributions.

Edit: Confirm the URL by checking the name of the root folder!

If the config was the primary issue (and it may still be nthary) you would get a php error, not a http "Object not found" error,

As for the config error, here are some steps to correct it:

1. Once you have confirmed which case your PHPMyAdmin is in, confirm that your config.inc.php is located in its root directory.

2. If it is, rename it to something else as a backup. Then copy the config.sample.inc.php (in the same directory) and rename it to config.inc.php

3. Check if it works.

4. If its does, then open up both the new config.inc.php (that works) and the backup you took earlier of your old one. Compare them and copy/replace the important parts that you want to carry over, the file (in its default state) isn't that long and it should be relatively easy to do so.

N.B. If the reason that you want your old config is because of security setup that you once had, I would definitely suggest still using the security wizard built into XAMPP so that you can be assured that you have the right configuration for the right version. There is no guarantee that different XAMPP/PHPMyAdmin versions implement security/anything in the same way.

Similar to another answer here, but change the http in the rewrite to to $scheme like so:

server {
        listen 80;
        server_name test.com;
        rewrite     ^ $scheme://www.test.com$request_uri? permanent;
}

And edit your main server block server_name variable as following:

server_name  www.test.com;

I had to do this to redirect www.test.com to test.com.

I actually prefer to use the html button form element and make it runat=server. The button element can hold other elements inside it. You can even add formatting inside it with span's or strong's. Here is an example:

<button id="BtnSave" runat="server"><img src="Images/save.png" />Save</button>

Easy: for_each is useful when you already have a function to handle every array item, so you don't have to write a lambda. Certainly, this

for_each(a.begin(), a.end(), a_item_handler);

is better than

for(auto& item: a) {
    a_item_handler(a);
}

Also, ranged for loop only iterates over whole containers from start to end, whilst for_each is more flexible.

You can try like:

   $("#myformid").submit(function(){
        //perform anythng
   });

Or even you can try like

$(".nextbutton").click(function() { 
    $('#form1').submit();
});

I was able to apply a background below the Scaffold (and even it's AppBar) by putting the Scaffold under a Stack and setting a Container in the first "layer" with the background image set and fit: BoxFit.cover property.

Both the Scaffold and AppBar has to have the backgroundColor set as Color.transparent and the elevation of AppBar has to be 0 (zero).

Voilà! Now you have a nice background below the whole Scaffold and AppBar! :)

Java is a verbose language.

If you are only 3 days in, and this is already bothering you, maybe you'd be better off learning a different language like Scala:

scala> println("Hello World")
Hello World

In a loose sense, this would qualify as using a "library" to enable shorter expressions ;)

If you use the Angular CLI to create your components, let's say CarComponent, it attaches app to the selector name (i.e app-car) and this throws the above error when you reference the component in the parent view. Therefore you either have to change the selector name in the parent view to let's say <app-car></app-car> or change the selector in the CarComponent to selector: 'car'

You can try:

select(data, matches("search_string"))

It is more general than contains - you can use regex (e.g. "one_string|or_the_other").

For more examples, see: http://rpackages.ianhowson.com/cran/dplyr/man/select.html.

Procedural generation is used heavily in the demoscene to create complex graphics in a small executable. Will Wright even said that he was inspired by the demoscene while making Spore. That may be your best place to start.

You need then a wrapping element with the bg image and in it the content element with the bg color:

<div id="Wrapper">

Excerpt from http://www.mingw.org/wiki/FAQ:

What's the difference between make and mingw32-make?

The "native" (i.e.: MSVCRT dependent) port of make is lacking in some functionality and has modified functionality due to the lack of POSIX on Win32. There also exists a version of make in the MSYS distribution that is dependent on the MSYS runtime. This port operates more as make was intended to operate and gives less headaches during execution. Based on this, the MinGW developers/maintainers/packagers decided it would be best to rename the native version so that both the "native" version and the MSYS version could be present at the same time without file name collision.

So,look into C:\MinGW\bin directory and first make sure what make executable, have you installed.(make.exe or mingw32-make.exe)

Before using MinGW, you should add C:\MinGW\bin; to the PATH environment variable using the instructions mentioned at http://www.mingw.org/wiki/Getting_Started/

Then cd to your directory, where you have the makefile and Try using mingw32-make.exe makefile.in or simply make.exe makefile.in(depending on executables in C:\MinGW\bin).

If you want a GUI based solution, install DevCPP IDE and then re-make.

• install stylebot extension from webstore https://chrome.google.com/webstore/detail/stylebot/oiaejidbmkiecgbjeifoejpgmdaleoha
• go to G-document, set appropriate minimal view mode
• click stylebot icon (css) in toolbar of Chrome
• click "Open Stylebot"
• on very first line of new window, which is reading "select an element", insert text .kix-page-compact::before
• set border-style to none

Other than that open the "View" menu at the top of the screen and un-check "Print Layout." Page breaks will now only be shown as a dashed line.

I would like to suggest an improvement to yanchenko's answer.

Instead of taking the first ip in the X_FORWARDED_FOR list, I take the first one which in not a known internal ip, as some routers don't respect the protocol, and you can see internal ips as the first value of the list.

PRIVATE_IPS_PREFIX = ('10.', '172.', '192.', )

def get_client_ip(request):
    """get the client ip from the request
    """
    remote_address = request.META.get('REMOTE_ADDR')
    # set the default value of the ip to be the REMOTE_ADDR if available
    # else None
    ip = remote_address
    # try to get the first non-proxy ip (not a private ip) from the
    # HTTP_X_FORWARDED_FOR
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
    if x_forwarded_for:
        proxies = x_forwarded_for.split(',')
        # remove the private ips from the beginning
        while (len(proxies) > 0 and
                proxies[0].startswith(PRIVATE_IPS_PREFIX)):
            proxies.pop(0)
        # take the first ip which is not a private one (of a proxy)
        if len(proxies) > 0:
            ip = proxies[0]

    return ip

I hope this helps fellow Googlers who have the same problem.

Webrtc is a part of peer to peer connection. We all know that before creating peer to peer connection, it requires handshaking process to establish peer to peer connection. And websockets play the role of handshaking process.

When you run WScript.Shell it runs under the local system account, this account has full rights on the machine, but no rights in Active Directory.

target.Value will give you a Variant type

target.Value2 will give you a Variant type as well but a Date is coerced to a Double

target.Text attempts to coerce to a String and will fail if the underlying Variant is not coercable to a String type

The safest thing to do is something like

Dim v As Variant
v = target.Value 'but if you don't want to handle date types use Value2

And check the type of the variant using VBA.VarType(v) before you attempt an explicit coercion.

Using SQL Server, here is another way to find last day of month :

SELECT DATEADD(MONTH,1,GETDATE())- day(DATEADD(MONTH,1,GETDATE()))

There's no such thing as a "complete" list. Different people have different ways of measuring -- for example, they might include slang, neologisms, multi-word phrases, offensive terms, foreign words, verb conjugations, and so on. Some people have even counted a million words! So you'll have to decide what you want in a word list.

jQuery Sparkle includes a custom event for this. The source can be seen here: http://github.com/balupton/jquery-sparkle/blob/master/scripts/resources/jquery.events.js

Here are few steps that must be followed carefully

1. First of all make sure that the WAMP server is running if it is not running, start the server.
2. Enter the URL http://localhost/phpmyadmin/setup in address bar of your browser.

3. Create a folder named config inside C:\wamp\apps\phpmyadmin, the folder inside apps may have different name like phpmyadmin3.2.0.1

4. Return to your browser in phpmyadmin setup tab, and click New server.

5. Change the authentication type to ‘cookie’ and leave the username and password field empty but if you change the authentication type to ‘config’ enter the password for username root.

6. Click save

7. Again click save in configuration file option.
8. Now navigate to the config folder. Inside the folder there will be a file named config.inc.php. Copy the file and paste it out of the folder (if the file with same name is already there then override it) and finally delete the folder.
9. Now you are done. Try to connect the mysql server again and this time you won’t get any error. --credits Bibek Subedi

Hadley has a very elegant solution to do this inside data frames in his reshape package, using the function colsplit.

require(reshape)
> df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
> df
  ID FOO
1 11 a|b
2 12 b|c
3 13 x|y
> df = transform(df, FOO = colsplit(FOO, split = "\\|", names = c('a', 'b')))
> df
  ID FOO.a FOO.b
1 11     a     b
2 12     b     c
3 13     x     y

As he stated, used the ImageButton widget. Copy your image file within the Res/drawable/ directory of your project. While in XML simply go into the graphic representation (for simplicity) of your XML file and click on your ImageButton widget that you added, go to its properties sheet and click on the [...] in the src: field. Simply navigate to your image file. Also, make sure you're using a proper format; I tend to stick with .png files for my own reasons, but they work.

When you want a flex item to occupy an entire row, set it to width: 100% or flex-basis: 100%, and enable wrap on the container.

The item now consumes all available space. Siblings are forced on to other rows.

.parent {
  display: flex;
  flex-wrap: wrap;
}

#range, #text {
  flex: 1;
}

.error {
  flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
  border: 1px dashed black;
}

<div class="parent">
  <input type="range" id="range">
  <input type="text" id="text">
  <label class="error">Error message (takes full width)</label>
</div>

More info: The initial value of the flex-wrap property is nowrap, which means that all items will line up in a row. MDN

>>> L = [0, 23, 234, 89, None, 0, 35, 9]
>>> [x for x in L if x is not None]
[0, 23, 234, 89, 0, 35, 9]

Just for fun, here's how you can adapt filter to do this without using a lambda, (I wouldn't recommend this code - it's just for scientific purposes)

>>> from operator import is_not
>>> from functools import partial
>>> L = [0, 23, 234, 89, None, 0, 35, 9]
>>> filter(partial(is_not, None), L)
[0, 23, 234, 89, 0, 35, 9]

An SMS Push is a message to tell the terminal to initiate the session. This happens because you can't initiate an IP session simply because you don't know the IP Adress of the mobile terminal. Mostly used to send a few lines of data to end recipient, to the effect of sending information, or reminding of events.

WAP Push is an SMS within the header of which is included a link to a WAP address. On receiving a WAP Push, the compatible mobile handset automatically gives the user the option to access the WAP content on his handset. The WAP Push directs the end-user to a WAP address where content is stored ready for viewing or downloading onto the handset. This wap address may be a page or a WAP site.

The user may “take action” by using a developer-defined soft-key to immediately activate an application to accomplish a specific task, such as downloading a picture, making a purchase, or responding to a marketing offer.

Insert a "line break" or a "paragraph break" in a RichTextBox "rtb" like this:

var range = new TextRange(rtb.SelectionStart, rtb.Selection.End); 
range.Start.Paragraph.ContentStart.InsertLineBreak();
range.Start.Paragraph.ContentStart.InsertParagraphBreak();

The only way to get the NewLine items is by inserting text with "\r\n" items first, and then applying more code which works on Selection and/or TextRange objects. This makes sure that the \par items are converted to \line items, are saved as desired, and are still correct when reopening the *.Rtf file. That is what I found so far after hard tries. My three code lines need to be surrounded by more code (with loops) to set the TextPointer items (.Start .End .ContentStart .ContentEnd) where the Lines and Breaks should go, which I have done with success for my purposes.

try this,

$('#id1').html($('#id1').html().replace('dogsss','dollsss'));

working sample

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

I have used the following:

public static double Index2Freq(int i, double samples, int nFFT) {
  return (double) i * (samples / nFFT / 2.);
}

public static int Freq2Index(double freq, double samples, int nFFT) {
  return (int) (freq / (samples / nFFT / 2.0));
}

The inputs are:

• i: Bin to access
• samples: Sampling rate in Hertz (i.e. 8000 Hz, 44100Hz, etc.)
• nFFT: Size of the FFT vector

I would suggest

sapply(foo, typeof)

if you need the actual types of the vectors in the data frame. class() is somewhat of a different beast.

If you don't need to get this information as a vector (i.e. you don't need it to do something else programmatically later), just use str(foo).

In both cases foo would be replaced with the name of your data frame.

I had the same issue and thought it can be simply solved by a cron job calling unattended-upgrade daily.

My intention is to have this as an automatic and quick solution to ensure that production container is secure and updated because it can take me sometime to update my images and deploy a new docker image with the latest security updates.

It is also possible to automate the image build and deployment with Github hooks

I've created a basic docker image with that automatically checks and installs security updates daily (can run directly by docker run itech/docker-unattended-upgrade ).

I also came across another different approach to check if the container needs an update.

My complete implementation:

Dockerfile

FROM ubuntu:14.04   

RUN apt-get update \
&& apt-get install -y supervisor unattended-upgrades \
&& rm -rf /var/lib/apt/lists/*

COPY install /install
RUN chmod 755 install
RUN /install

COPY start /start
RUN chmod 755 /start

Helper scripts

install

#!/bin/bash
set -e

cat > /etc/supervisor/conf.d/cron.conf <<EOF
[program:cron]
priority=20
directory=/tmp
command=/usr/sbin/cron -f
user=root
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/%(program_name)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s.log
EOF

rm -rf /var/lib/apt/lists/*

ENTRYPOINT ["/start"]

start

#!/bin/bash

set -e

echo "Adding crontab for unattended-upgrade ..."
echo "0 0 * * * root /usr/bin/unattended-upgrade" >> /etc/crontab

# can also use @daily syntax or use /etc/cron.daily

echo "Starting supervisord ..."
exec /usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf

Edit

I developed a small tool docker-run that runs as docker container and can be used to update packages inside all or selected running containers, it can also be used to run any arbitrary commands.

Can be easily tested with the following command:

docker run --rm -v /var/run/docker.sock:/tmp/docker.sock itech/docker-run exec

which by default will execute date command in all running containers and display the results. If you pass update instead of exec it will execute apt-get update followed by apt-get upgrade -y in all running containers

While @tymeJV gave a correct answer, the way to do this to be inline with angular would be:

ng-click="hidePrefs()"

and then in your controller:

$scope.hidePrefs = function() {  
  $scope.prefs = false;
}

Not all of the answers worked for my various python configurations so this solution only uses the subprocess module. However, copy_keyword has to be pbcopy for Mac or clip for Windows:

import subprocess
subprocess.run('copy_keyword', universal_newlines=True, input='New Clipboard Value ')

Here's some more extensive code that automatically checks what the current operating system is:

import platform
import subprocess

copy_string = 'New Clipboard Value '

# Check which operating system is running to get the correct copying keyword.
if platform.system() == 'Darwin':
    copy_keyword = 'pbcopy'
elif platform.system() == 'Windows':
    copy_keyword = 'clip'

subprocess.run(copy_keyword, universal_newlines=True, input=copy_string)

You can do the following while read loop, that will be fed by the result of the grep command using the so called process substitution:

while IFS= read -r result
do
    #whatever with value $result
done < <(grep "xyz" abc.txt)

This way, you don't have to store the result in a variable, but directly "inject" its output to the loop.

Note the usage of IFS= and read -r according to the recommendations in BashFAQ/001: How can I read a file (data stream, variable) line-by-line (and/or field-by-field)?:

The -r option to read prevents backslash interpretation (usually used as a backslash newline pair, to continue over multiple lines or to escape the delimiters). Without this option, any unescaped backslashes in the input will be discarded. You should almost always use the -r option with read.

In the scenario above IFS= prevents trimming of leading and trailing whitespace. Remove it if you want this effect.

Regarding the process substitution, it is explained in the bash hackers page:

Process substitution is a form of redirection where the input or output of a process (some sequence of commands) appear as a temporary file.

Most browsers will pick up favicon.ico from the root directory of the site without needing to be told; but they don't always update it with a new one right away.

However, I usually go for the second of your examples:

<link rel='shortcut icon' type='image/x-icon' href='/favicon.ico' />

I was able to set up github actions to automatically commit the results of a node build command (yarn build in my case but it should work with npm too) to the gh-pages branch whenever a new commit is pushed to master.

While not completely ideal as i'd like to avoid committing the built files, it seems like this is currently the only way to publish to github pages.

I based my workflow off of this guide for a different react library, and had to make the following changes to get it to work for me:

• updated the "setup node" step to use the version found here since the one from the sample i was basing it off of was throwing errors because it could not find the correct action.
• remove the line containing yarn export because that command does not exist and it doesn't seem to add anything helpful (you may also want to change the build line above it to suit your needs)
• I also added an env directive to the yarn build step so that I can include the SHA hash of the commit that generated the build inside my app, but this is optional

Here is my full github action:

name: github pages

on:
    push:
        branches:
        - master

    deploy:

Alternative solution

The docs for next.js also provides instructions for setting up with Vercel which appears to be a hosting service for node.js apps similar to github pages. I have not tried this though and so cannot speak to how well it works.

The removeAttr() function only removes HTML attributes. The display is not a HTML attribute, it's a CSS property. You'd like to use css() function instead to manage CSS properties.

But jQuery offers a show() function which does exactly what you want in a concise call:

$("span").show();

ConfigurationManager.AppSettings is actually a property, so you need to use square brackets.

Overall, here's what you need to do:

SqlConnection con= new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);

The problem is that you tried to set con to a string, which is not correct. You have to either pass it to the constructor or set con.ConnectionString property.

On platforms where they both have the same size the answer is nothing. They both represent signed 4 byte values.

However you cannot depend on this being true. The size of long and int are not definitively defined by the standard. It's possible for compilers to give the types different sizes and hence break this assumption.

^https?:\/\/(.*) where (.*) is match everything else after https://

You might also consider Microsoft Enterprise Library Logging Block. It comes with nice designer.

This is just a warning and it doesn't make problem for your project to run, you can just ignore it and continue coding. But if you're obsessed about clean coding, same as me, you have two options:

1. Hover the mouse on warning in VS Code or any IDE and use quick fix to remove white spaces.
2. Press f1 then type trim trailing whitespace.

Fixed positioning is supposed to define everything in relation to the viewport, so position:fixed is always going to do that. Try using position:relative on the child div instead. (I realize you might need the fixed positioning for other reasons, but if so - you can't really make the width match it's parent with out JS without inherit)

strncpy(otherString, someString, 5);

Don't forget to allocate memory for otherString.

We built a very simple free/opensource component that adds SAML support for ASP.NET apps https://github.com/jitbit/AspNetSaml

Basically it's just one short C# file you can throw into your project (or install via Nuget) and use it with your app

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

One idea:

try {
    int i = Integer.parseInt(myString);
    if (i < 0) {
        // Error, negative input
    }
} catch (NumberFormatException e) {
    // Error, not a number.
}

There is also, in commons-lang library the CharUtils class that provides the methods isAsciiNumeric() to check that a character is a number, and isAsciiAlpha() to check that the character is a letter...

Its based on from which file you are trying to access those files.

If it is in the same folder where your working project file is, then you can use just the file name. no need of path.

If it is in the another folder which is under the same parent folder of your working project file then you can use location like in the following /javascript/sample.js

In your example if you are trying to access your js file from your html file you can use the following location

../javascript/sample.js

the prefix../ will go to the parent folder of the file(Folder upward journey)

Another way starting from c# 7.0 would be using local functions. You could name the local function with a meaningful name, and call it directly before declaring it (for clarity). Here is your example rewritten:

public void Method()
{
    // Some code here
    bool something = true, something2 = true;

    DoSomething();
    void DoSomething()
    {
        if (something)
        {
            //some code
            if (something2)
            {
                // now I should break from ifs and go to te code outside ifs
                return;
            }
            return;
        }
    }

    // The code i want to go if the second if is true
    // More code here
}

Good answers above- if you're looking for something reusable here is the code. Note that you might want to check the decimal places value, and this may overflow.

public static decimal TruncateToDecimalPlace(this decimal numberToTruncate, int decimalPlaces)
{
    decimal power = (decimal)(Math.Pow(10.0, (double)decimalPlaces));

    return Math.Truncate((power * numberToTruncate)) / power;
}

You have to add your jquery script to your chrome-extension project and to the background section of your manifest.json like this :

  "background":
    {
        "scripts": ["thirdParty/jquery-2.0.3.js", "background.js"]
    }

If you need jquery in a content_scripts, you have to add it in the manifest too:

"content_scripts": 
    [
        {
            "matches":["http://website*"],
            "js":["thirdParty/jquery.1.10.2.min.js", "script.js"],
            "css": ["css/style.css"],
            "run_at": "document_end"
        }
    ]

This is what I did.

Also, if I recall correctly, the background scripts are executed in a background window that you can open via chrome://extensions.

Conclusion,

to_char works in its own way

So,

Always use this format YYYY-MM-DD for comparison instead of MM-DD-YY or DD-MM-YYYY or any other format

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

@echo off

set countfiles=10

:loop

set /a countfiles -= 1

echo hi

if %countfiles% GTR 0 goto loop

pause

on the first "set countfiles" the 10 you see is the amount it will loop the echo hi is the thing you want to loop

Follow these steps, respectively for rename column migration file.

1- Is there Doctrine/dbal library in your project. If you don't have run the command first

composer require doctrine/dbal

2- create update migration file for update old migration file. Warning (need to have the same name)

php artisan make:migration update_oldFileName_table

for example my old migration file name: create_users_table update file name should : update_users_table

3- update_oldNameFile_table.php

Schema::table('users', function (Blueprint $table) {
$table->renameColumn('from', 'to');
});

'from' my old column name and 'to' my new column name

4- Finally run the migrate command

php artisan migrate

TLDR; Here's why:

The reason this works is because gulp tries to run your gulpfile.js using your locally installed version of gulp, see here. Hence the reason for a global and local install of gulp.

Essentially, when you install gulp locally the script isn't in your PATH and so you can't just type gulp and expect the shell to find the command. By installing it globally the gulp script gets into your PATH because the global node/bin/ directory is most likely on your path.

To respect your local dependencies though, gulp will use your locally installed version of itself to run the gulpfile.js.

If you are running python version 3.9 pandas wont work as of now. So install python version 3.7 or below to mitigate this issue. Or else if you want to stick with python 3.9 try install pandas by compiling the library

For me, I forgot that I had changed the password on Github.com, and my keychain for shell authentication never updated to that new password. Deleting everything git from my keychain and then re-running the git request helped solve the issue, prompting me again for the new password.

You need to install the APK on the emulator. You can do this with the adb command line tool that is included in the Android SDK.

adb -e install -r yourapp.apk

Once you've done that you should be able to run the app.

The -e and -r flags might not be necessary. They just specify that you are using an emulator (if you also have a device connected) and that you want to replace the app if it already exists.

The following answer only applies to Git version 1.x, but to Git version 2.x.

You want git add -A:

git add -A stages All;

git add . stages new and modified, without deleted;

git add -u stages modified and deleted, without new.

The WPF DataGrid has an IsReadOnly property that you can set to True to ensure that users cannot edit your DataGrid's cells.

You can also set this value for individual columns in your DataGrid as needed.

I animated fading in of Recyclerview items when they first appear as shown in the code below. Perhaps this will be of use to someone.

private final static int FADE_DURATION = 1000; //FADE_DURATION in milliseconds

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    holder.getTextView().setText("some text");

    // Set the view to fade in
    setFadeAnimation(holder.itemView);            
}

private void setFadeAnimation(View view) {
    AlphaAnimation anim = new AlphaAnimation(0.0f, 1.0f);
    anim.setDuration(FADE_DURATION);
    view.startAnimation(anim);
}

You can also replace setFadeAnimation() with the following setScaleAnimation() to animate appearance of items by scaling them from a point:

private void setScaleAnimation(View view) {
    ScaleAnimation anim = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
    anim.setDuration(FADE_DURATION);
    view.startAnimation(anim);
}

The code above has some warts in so far as when you scroll the RecyclerView items always fade or scale. If you wish you can add code to just allow the animation to happen when the fragment or activity containing the RecyclerView is first created (e.g. get the system time on creation and only allow animation for the first FADE_DURATION milliseconds).

I know this is an old post, in SQL Server:

select  isnull(town,'TOTAL') Town, count(*) cnt
from    user
group by town WITH ROLLUP

Town         cnt
Copenhagen   58
NewYork      58
Athens       58
TOTAL        174

You need to modify the name of the DB in the file .env (and if need in .env.example) I solved my problem with this little correction.

Otherwise, you have function alpha in package scales in which you can directly input your vector of colors (even if they are factors as in your example):

library(scales)
cols <- cut(z, 6, labels = c("pink", "red", "yellow", "blue", "green", "purple"))
plot(x, y, main= "Fragment recruitment plot - FR-HIT", 
     ylab = "Percent identity", xlab = "Base pair position", 
     col = alpha(cols, 0.4), pch=16) 
# For an alpha of 0.4, i. e. an opacity of 40%.

As complement to Mark's answer, the compile function does not have access to scope, but the link function does.

I really recommend this video; Writing Directives by Misko Hevery (the father of AngularJS), where he describes differences and some techniques. (Difference between compile function and link function at 14:41 mark in the video).

Before The execution of following code, I assume you have created a database and a table (with columns Name (varchar), Age(INT) and Address(varchar)) inside that database. Also please update your SQL Server name , UserID, password, DBname and table name in the code below.

DTO classes are used to serialize/deserialize data from different sources. When you want to deserialize a object from a source, does not matter what external source it is: service, file, database etc. you may be only want to use some part of that but you want an easy way to deserialize that data to an object. after that you copy that data to the XModel you want to use. A serializer is a beautiful technology to load DTO objects. Why? you only need one function to load (deserialize) the object.

Not the best solution, but here is what I got:

1) Annotate getter you want to initialize with this annotation:

@Retention(RetentionPolicy.RUNTIME)
public @interface Lazy {

}

2) Use this method (can be put in a generic class, or you can change T with Object class) on a object after you read it from database:

    public <T> void forceLoadLazyCollections(T entity) {

    Session session = getSession().openSession();
    Transaction tx = null;
    try {

        tx = session.beginTransaction();
        session.refresh(entity);
        if (entity == null) {
            throw new RuntimeException("Entity is null!");
        }
        for (Method m : entityClass.getMethods()) {

            Lazy annotation = m.getAnnotation(Lazy.class);
            if (annotation != null) {
                m.setAccessible(true);
                logger.debug(" method.invoke(obj, arg1, arg2,...); {} field", m.getName());
                try {
                    Hibernate.initialize(m.invoke(entity));
                }
                catch (Exception e) {
                    logger.warn("initialization exception", e);
                }
            }
        }

    }
    finally {
        session.close();
    }
}

No. Unlike other virtual methods, where you would explicitly call the Base method from the Derived to 'chain' the call, the compiler generates code to call the destructors in the reverse order in which their constructors were called.

"netstat -natp" is what I always use.

Well I got this Issue too in my few websites and all i need to do is customize the content fetler for HTML entites. before that more i delete them more i got, so just change you html fiter or parsing function for the page and it worked. Its mainly due to HTML editors in most of CMSs. the way they store parse the data caused this issue (In My case). May this would Help in your case too

//Runs function after x seconds

public static func runThisAfterDelay(seconds: Double, after: @escaping () -> Void) {
    runThisAfterDelay(seconds: seconds, queue: DispatchQueue.main, after: after)
}

public static func runThisAfterDelay(seconds: Double, queue: DispatchQueue, after: @escaping () -> Void) {
    let time = DispatchTime.now() + Double(Int64(seconds * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)
    queue.asyncAfter(deadline: time, execute: after)
}

//Use:-

runThisAfterDelay(seconds: x){
  //write your code here
}

Try adding this:

$.ajax({
    url: "ajax.aspx",
    type:'get',
    data: {ajaxid:4, UserID: UserID , EmailAddress: encodeURIComponent(EmailAddress)},
    dataType: 'json',
    success: function(response) {
      //Do Something
    },
    error: function(xhr) {
    //Do Something to handle error
    }
});

Depends on what datatype is expected, you can assign html, json, script, xml

Also:

(value % 1) == 0

would work!

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. text

Generally issues like this are related to any of the following need to be looked at:

• firewall settings from the web server to the database server
• connection string errors
• enable the appropriate protocol pipes/ tcp-ip

Try connecting to sql server with sql management server on the system that sql server is installed on and work from there. Pay attention to information in the errorlogs.

to set text in kotlin

textview.text = "write here"

Try something like this:

df.select([c for c in df.columns if c in ['_2','_4','_5']]).show()

I had the same issue when I was using GIT bash to merge master branch in to my feature branch. I followed the following steps to overcome this.

1. press 'i' (To insert a merge message)
2. write your merge message
3. press esc button (To go back)
4. write ':wq' (write & quit)
5. then press enter

I solved my problem by running below command

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

If you wish to have "Save as" dialog, just pass image into php script, which adds appropriate headers

Example "all-in-one" script script.php

<?php if(isset($_GET['image'])):
    $image = $_GET['image'];

    if(preg_match('#^data:image/(.*);base64,(.*)$#s', $image, $match)){
        $base64 = $match[2];
        $imageBody = base64_decode($base64);
        $imageFormat = $match[1];

        header('Content-type: application/octet-stream');
        header("Pragma: public");
        header("Expires: 0");
        header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
        header("Cache-Control: private", false); // required for certain browsers
        header("Content-Disposition: attachment; filename=\"file.".$imageFormat."\";" ); //png is default for toDataURL
        header("Content-Transfer-Encoding: binary");
        header("Content-Length: ".strlen($imageBody));
        echo $imageBody;
    }
    exit();
endif;?>

After doing more research, and reviewing this link: https://git.wiki.kernel.org/articles/g/i/t/GitSvnComparison_cb82.html

(Some extracts below):

• It's incredibly fast. No other SCM that I have used has been able to keep up with it, and I've used a lot, including Subversion, Perforce, darcs, BitKeeper, ClearCase and CVS.
• It's fully distributed. The repository owner can't dictate how I work. I can create branches and commit changes while disconnected on my laptop, then later synchronize that with any number of other repositories.
• Synchronization can occur over many media. An SSH channel, over HTTP via WebDAV, by FTP, or by sending emails holding patches to be applied by the recipient of the message. A central repository isn't necessary, but can be used.
• Branches are even cheaper than they are in Subversion. Creating a branch is as simple as writing a 41 byte file to disk. Deleting a branch is as simple as deleting that file.
• Unlike Subversion branches carry along their complete history. without having to perform a strange copy and walk through the copy. When using Subversion I always found it awkward to look at the history of a file on branch that occurred before the branch was created. from #git: spearce: I don't understand one thing about SVN in the page. I made a branch i SVN and browsing the history showed the whole history a file in the branch
• Branch merging is simpler and more automatic in Git. In Subversion you need to remember what was the last revision you merged from so you can generate the correct merge command. Git does this automatically, and always does it right. Which means there's less chance of making a mistake when merging two branches together.
• Branch merges are recorded as part of the proper history of the repository. If I merge two branches together, or if I merge a branch back into the trunk it came from, that merge operation is recorded as part of the repostory history as having been performed by me, and when. It's hard to dispute who performed the merge when it's right there in the log.
• Creating a repository is a trivial operation: mkdir foo; cd foo; git init That's it. Which means I create a Git repository for everything these days. I tend to use one repository per class. Most of those repositories are under 1 MB in disk as they only store lecture notes, homework assignments, and my LaTeX answers.
• The repository's internal file formats are incredible simple. This means repair is very easy to do, but even better because it's so simple its very hard to get corrupted. I don't think anyone has ever had a Git repository get corrupted. I've seen Subversion with fsfs corrupt itself. And I've seen Berkley DB corrupt itself too many times to trust my code to the bdb backend of Subversion.
• Git's file format is very good at compressing data, despite it's a very simple format. The Mozilla project's CVS repository is about 3 GB; it's about 12 GB in Subversion's fsfs format. In Git it's around 300 MB.

After reading all this, I'm convinced that Git is the way to go (although a little bit of learning curve exists). I have used Git and SVN on Windows platforms as well.

I'd love to hear what others have to say after reading the above?

I connected to a VPN and it worked. I was using school's WiFi.

iPhoney is designed specifically for Mac users

you can read about it and download it here

For me it was server responding with something other than 200 and the response was not json formatted. I ended up doing this before the json parse:

# this is the https request for data in json format
response_json = requests.get() 

# only proceed if I have a 200 response which is saved in status_code
if (response_json.status_code == 200):  
     response = response_json.json() #converting from json to dictionary using json library

Just replace it:

<li><a href="" data-toggle="modal" data-target="#modalRegister">Register</a></li>

Instead of:

<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>

Note that COLUMNS is:

1. NOT an environment variable. It is an ordinary bash parameter that is set by bash itself.
2. Set automatically upon receipt of a SIGWINCH signal.

That second point usually means that your COLUMNS variable will only be set in your interactive shell, not in a bash script.

If your script's stdin is connected to your terminal you can manually look up the width of your terminal by asking your terminal:

tput cols

And to use this in your SVN command:

svn diff "$@" --diff-cmd /usr/bin/diff -x "-y -w -p -W $(tput cols)"

(Note: you should quote "$@" and stay away from eval ;-))

Loops may achieve a performance gain for your program. Recursion may achieve a performance gain for your programmer. Choose which is more important in your situation!

Something like this could be it?

HTML

 <div class="random">
        SOMETHING
 </div>

CSS

body{

    text-align: center;
}

.random{

    width: 60%;
    margin: auto;
    background-color: yellow;
    display:block;

}

DEMO: http://jsfiddle.net/t5Pp2/2/

Edit: adding display:block doesn't ruin the thing, so...

You can also set the margin to: margin: 0 auto 0 auto; just to be sure it centers only this way not from the top too.

If you are going to call relative.py directly and i.e. if you really want to import from a top level module you have to explicitly add it to the sys.path list.
Here is how it should work:

# Add this line to the beginning of relative.py file
import sys
sys.path.append('..')

# Now you can do imports from one directory top cause it is in the sys.path
import parent

# And even like this:
from parent import Parent

If you think the above can cause some kind of inconsistency you can use this instead:

sys.path.append(sys.path[0] + "/..")

sys.path[0] refers to the path that the entry point was ran from.

To access services in two different namespaces you can use url like this:

HTTP://<your-service-name>.<namespace-with-that-service>.svc.cluster.local

To list out all your namespaces you can use:

kubectl get namespace

And for service in that namespace you can simply use:

kubectl get services -n <namespace-name>

this will help you.

The bug with ignored BOM seems to be fixed for Excel 2013. I had same problem with Cyrillic letters, but adding BOM character \uFEFF did help.

if (strcmp("hello", "hello") = 0)

Is trying to assign 0 to function return value which isn't lvalue.

Function return values are not lvalue (no storage for it), so any attempt to assign value to something that is not lvalue result in error.

Best practice to avoid such mistakes in if conditions is to use constant value on left side of comparison, so even if you use "=" instead "==", constant being not lvalue will immediately give error and avoid accidental value assignment and causing false positive if condition.

From WikiAnswers:

• A schema is collection of database objects, including logical structures such as tables, views, sequences, stored procedures, synonyms, indexes, clusters, and database links.
• A user owns a schema.
• A user and a schema have the same name.
• The CREATE USER command creates a user. It also automatically creates a schema for that user.
• The CREATE SCHEMA command does not create a "schema" as it implies, it just allows you to create multiple tables and views and perform multiple grants in your own schema in a single transaction.
• For all intents and purposes you can consider a user to be a schema and a schema to be a user.

Furthermore, a user can access objects in schemas other than their own, if they have permission to do so.

Although, as mentioned, you could add a second parameter here to indicate you want an array returned:

$array = json_decode($json, true);

Many people might prefer to cast the results instead:

$array = (array)json_decode($json);

It might be more clear to read.

I've devised the below demo using a mix of tricks which allows simulating if/else scenarios for some properties. Any property which is numerical in its essence is easy target for this method, but properties with text values are.

This code has 3 if/else scenarios, for opacity, background color & width. All 3 are governed by two Boolean variables bool and its opposite notBool.

Those two Booleans are the key to this method, and to achieve a Boolean out of a none-boolean dynamic value, requires some math which luckily CSS allows using min & max functions.

Obviously those functions (min/max) are supported in recent browsers' versions which also supports CSS custom properties (variables).

var elm = document.querySelector('div')

setInterval(()=>{
  elm.style.setProperty('--width', Math.round(Math.random()*80 + 20))
}, 1000)

:root{
   --color1: lightgreen;
   --color2: salmon;
   --width: 70;  /* starting value, randomly changed by javascript every 1 second */
}

div{
 --widthThreshold: 50;
 --is-width-above-limit: Min(1, Max(var(--width) - var(--widthThreshold), 0));
 --is-width-below-limit: calc(1 - var(--is-width-above-limit));
 
 --opacity-wide: .4;     /* if width is ABOVE 50 */
 --radius-narrow: 10px;  /* if width is BELOW 50 */
 --radius-wide: 60px;    /* if width is ABOVE 50 */
 --height-narrow: 80px;  /* if width is ABOVE 50 */
 --height-wide: 160px;   /* if width is ABOVE 50 */
 
 --radiusToggle: Max(var(--radius-narrow), var(--radius-wide) * var(--is-width-above-limit));
 --opacityToggle: calc(calc(1 + var(--opacity-wide)) - var(--is-width-above-limit));
 --colorsToggle: var(--color1) calc(100% * var(--is-width-above-limit)), 
                 var(--color2) calc(100% * var(--is-width-above-limit)), 
                 var(--color2) calc(100% * (1 - var(--is-width-above-limit)));
  
 --height: Max(var(--height-wide) * var(--is-width-above-limit), var(--height-narrow));
 
 height: var(--height);
 text-align: center;
 line-height: var(--height);

 width: calc(var(--width) * 1%);
 opacity: var(--opacityToggle);
 border-radius: var(--radiusToggle);
 background: linear-gradient(var(--colorsToggle));

 transition: .3s;
}

/* prints some variables */
div::before{
  counter-reset: aa var(--width);
  content: counter(aa)"%";
}

div::after{
  counter-reset: bb var(--is-width-above-limit);
  content: " is over 50% ? "counter(bb);
}

<div></div>

Another simply way using clamp:

label{ --width: 150 }
input:checked + div{ --width: 400 }

div{
  --isWide: Clamp(0,   (var(--width) - 150) * 99999  , 1);
  width: calc(var(--width) * 1px);
  height: 150px;
  border-radius: calc(var(--isWide) * 20px); /* if wide - add radius */
  background: lightgreen;
}

<label>
<input type='checkbox' hidden> 
<div>Click to toggle width</div>
</label>

Best so far:

I have come up with a totally unique method, which is even simpler!

This method is so cool because it is so easy to implement and also to understand. it is based on animation step() function.

Since bool can be easily calculated as either 0 or 1, this value can be used in the step! if only a single step is defined, then the if/else problem is solved.

Using the keyword forwards persist the changes.

In PM:

Install-Package NuGet.CommandLine

Close Visual Studio and open it again.

You can use android:theme="@android:style/Theme.Dialog" to do that. Create an activity and in your AndroidManifest.xml define the activity as:

    <activity android:name=".activities.YourActivity"

It doesn't seem you can serialize an instance, you'd have to serialize a QuerySet of one object.

from django.core import serializers
from models import *

def getUser(request):
    return HttpResponse(json(Users.objects.filter(id=88)))

I run out of the svn release of django, so this may not be in earlier versions.

Using this function you can get Image Bitmap. Just pass image url

 public Bitmap getBitmapFromURL(String strURL) {
      try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
      } catch (IOException e) {
        e.printStackTrace();
        return null;
      }
 }

Use this echo statement

 echo -e "Hai\nHello\nTesting\n"

The output is

Hai
Hello
Testing

If you have a ADO.Net DataTable you could do

int sum = 0;
foreach(DataRow dr in dataTable.Rows)
{
   sum += Convert.ToInt32(dr["Amount"]);
}

If you want to query the database table, you could use

Select Sum(Amount) From DataTable

In C, the order that you define things often matters. Either move the definition of outchar to the top, or provide a prototype at the top, like this:

#include <stdio.h> #include <stdlib.h>  void outchar(char ch);  int main() {     outchar('A');     outchar('B');     outchar('C');     return 0; }  void outchar(char ch) {     printf("%c", ch); } 

Also, you should be specifying the return type of every function. I added that for you.

You can use Culture to get month name for your country like:

System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("ar-EG");
string FormatDate = DateTime.Now.ToString("dddd., MMM dd yyyy, hh:MM tt", culture);

You need not specify receiver. You can use adb instead.

adb shell am broadcast -a com.whereismywifeserver.intent.TEST 
--es sms_body "test from adb"

For more arguments such as integer extras, see the documentation.

Yes , You can use conditional statement with EJS like if else , ternary operator or even switch case also

For Example

Ternary operator : <%- role == 'Admin' ? 'Super Admin' : role == 'subAdmin' ? 'Sub Admin' : role %>

Switch Case

<% switch (role) {
case 'Admin' : %>
        Super Admin
        <% break;

case 'eventAdmin' : %>
        Event Admin
        <% break;

case 'subAdmin' : %>
        Sub Admin
        <% break;

} %>

Probably your new domain contain / ? If so, try using separator other than / in sed, e.g. #, , etc.

find ./ -type f -exec sed -i 's#192.168.20.1#new.domain.com#' {} \;

It would also be good to enclose s/// in single quote rather than double quote to avoid variable substitution or any other unexpected behaviour

I'm using PHP and solved this by using version 1.1.4 of google-api-php-client

Assuming the following code is used to redirect a user to the Google authentication page:

 $client = new Google_Client();
 $client->setAuthConfigFile('/path/to/config/file/here');
 $client->setRedirectUri('https://redirect/url/here');
 $client->setAccessType('offline'); //optional
 $client->setScopes(['profile']); //or email
 $auth_url = $client->createAuthUrl();
 header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
 exit();

Assuming a valid authentication code is returned to the redirect_url, the following will generate a token from the authentication code as well as provide basic profile information:

 //assuming a successful authentication code is return
 $authentication_code = 'code-returned-by-google';
 $client = new Google_Client();
 //.... configure $client object code goes here
 $client->authenticate($authentication_code);
 $token_data = $client->getAccessToken();

 //get user email address
 $google_oauth =new Google_Service_Oauth2($client);
 $google_account_email = $google_oauth->userinfo->get()->email;
 //$google_oauth->userinfo->get()->familyName;
 //$google_oauth->userinfo->get()->givenName;
 //$google_oauth->userinfo->get()->name;
 //$google_oauth->userinfo->get()->gender;
 //$google_oauth->userinfo->get()->picture; //profile picture

However, location is not returned. New YouTube accounts don't have YouTube specific usernames

The result '\\&' is only displayed - actually the string is \&:

>>> str = '&'
>>> new_str = str.replace('&', '\&')
>>> new_str
'\\&'
>>> print new_str
\&

Try it in a shell.

This code will help you.

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] 
initWithTarget:self action:@selector(showHideNavbar:)];
[self.view addGestureRecognizer:tapGesture];

-(void) showHideNavbar:(id) sender 
{ 
// write code to show/hide nav bar here 
// check if the Navigation Bar is shown
if (self.navigationController.navigationBar.hidden == NO)
{
// hide the Navigation Bar
[self.navigationController setNavigationBarHidden:YES animated:YES];
}
// if Navigation Bar is already hidden
else if (self.navigationController.navigationBar.hidden == YES)
{
// Show the Navigation Bar
[self.navigationController setNavigationBarHidden:NO animated:YES];
}
}

The simplest way to do this is by using object-fit:

<div class="container">
  <img src="path/to/image.jpg">
</div>

.container{
   height: 300px;
}

.container img{
  height: 100%;
  width: 100%;
  object-fit: cover;
}

If you're using Bootstrap, just add the img-responsive class and change to

.container img{
    object-fit: cover;
}

According to HTTP terms, The PUT request is just-like a database update statement. PUT - is used for modifying existing resource (Previously POSTED). On the other hand the PATCH request is used to update some portion of existing resource.

For Example:

Customer Details:

// This is just a example.

firstName = "James";
lastName = "Anderson";
email = "[email protected]";
phoneNumber = "+92 1234567890";
//..

When we want to update to entire record ? we have to use Http PUT verb for that.

such as:

// Customer Details Updated.

firstName = "James++++";
lastName = "Anderson++++";
email = "[email protected]";
phoneNumber = "+92 0987654321";
//..

On the other hand if we want to update only the portion of the record not the entire record then go for Http PATCH verb. such as:

   // Only Customer firstName and lastName is Updated.

    firstName = "Updated FirstName";
    lastName = "Updated LastName";
   //..

PUT VS POST:

When using PUT request we have to send all parameter such as firstName, lastName, email, phoneNumber Where as In patch request only send the parameters which one we want to update and it won't effecting or changing other data.

List myList = new ArrayList();
Collections.addAll(myList, filesOrig); 

In past projects I worked on, the endpoint was a relative property. That is to say it may or may not have been appended to, but it always contained the protocol://host:port/partOfThePath.

If the service being called had a dynamic part to it, for example a ?param=dynamicValue, then that part would get added to the endpoint. But many times the endpoint could be used as is without having to be amended.

Whats important to understand is what an endpoint is not and how it helps. For example an alternative way to pass the information stored in an endpoint would be to store the different parts of the endpoint in separate properties. For example:

hostForServiceA=someIp
portForServiceA=8080
pathForServiceA=/some/service/path
hostForServiceB=someIp
portForServiceB=8080
pathForServiceB=/some/service/path

Or if the same host and port across multiple services:

host=someIp
port=8080
pathForServiceA=/some/service/path
pathForServiceB=/some/service/path

In those cases the full URL would need to be constructed in your code as such:

String url = "http://" + host + ":" + port + pathForServiceA  + "?" + dynamicParam + "=" + dynamicValue;

In contract this can be stored as an endpoint as such

serviceAEndpoint=http://host:port/some/service/path?dynamicParam=

And yes many times we stored the endpoint up to and including the '='. This lead to code like this:

String url = serviceAEndpoint + dynamicValue;

Hope that sheds some light.

Use update instead of stop

http://api.jqueryui.com/sortable/

update( event, ui )

Type: sortupdate

This event is triggered when the user stopped sorting and the DOM position has changed.

.

stop( event, ui )

Type: sortstop

This event is triggered when sorting has stopped. event Type: Event

I see std::weak_ptr<T> as a handle to a std::shared_ptr<T>: It allows me to get the std::shared_ptr<T> if it still exists, but it will not extend its lifetime. There are several scenarios when such point of view is useful:

// Some sort of image; very expensive to create.
std::shared_ptr< Texture > texture;

// A Widget should be able to quickly get a handle to a Texture. On the
// other hand, I don't want to keep Textures around just because a widget
// may need it.

struct Widget {
    std::weak_ptr< Texture > texture_handle;
    void render() {
        if (auto texture = texture_handle.get(); texture) {
            // do stuff with texture. Warning: `texture`
            // is now extending the lifetime because it
            // is a std::shared_ptr< Texture >.
        } else {
            // gracefully degrade; there's no texture.
        }
    }
};

Another important scenario is to break cycles in data structures.

// Asking for trouble because a node owns the next node, and the next node owns
// the previous node: memory leak; no destructors automatically called.
struct Node {
    std::shared_ptr< Node > next;
    std::shared_ptr< Node > prev;
};

// Asking for trouble because a parent owns its children and children own their
// parents: memory leak; no destructors automatically called.
struct Node {
    std::shared_ptr< Node > parent;
    std::shared_ptr< Node > left_child;
    std::shared_ptr< Node > right_child;
};

// Better: break dependencies using a std::weak_ptr (but not best way to do it;
// see Herb Sutter's talk).
struct Node {
    std::shared_ptr< Node > next;
    std::weak_ptr< Node > prev;
};

// Better: break dependencies using a std::weak_ptr (but not best way to do it;
// see Herb Sutter's talk).
struct Node {
    std::weak_ptr< Node > parent;
    std::shared_ptr< Node > left_child;
    std::shared_ptr< Node > right_child;
};

Herb Sutter has an excellent talk that explains the best use of language features (in this case smart pointers) to ensure Leak Freedom by Default (meaning: everything clicks in place by construction; you can hardly screw it up). It is a must watch.

So it turns out that almost all the default settings for HikariCP work for me except the number of DB connections. I set that property in my application.properties:

spring.datasource.maximumPoolSize=20

And Andy Wilkinson is correct as far as I can tell in that you can't use the dataSourceClassName configuration approach for HikariCP with Spring Boot.

More recent versions of IntelliJ (certainly WebStorm and PhpStorm) have made this change even easier by adding a Help >> Change Memory Settings menu item that opens a dialog where the memory limit can be set.

I just found in my case Kaspersky Internet Security 2019 Firewall was blocking net access for python. Disabling firewall working smoothly. Or adding a exception rules for python app and all file extension with *.py will also work.

I made some changes to dina's answer to avoid attempting to download/combine 1200 parts if there aren't that many.

I also found it helpful to sort by waterfall in the network tab of chrome. This will sort by the time the files are downloaded, so when you are streaming a video the most recently downloaded parts will be at the top, making it easy to find the .ts links.

#!/bin/bash

# Name of the containing folder
GROUP="My Videos"

# Example link: https://vids.net/ABCAED/AADDCDE/m3u8/AADDCDE/AADDCDE_0.ts
# Insert below as: https://vids.net/ABCAED/AADDCDE/m3u8/AADDCDE/AADDCDE

# INSERT LINKS TO VIDEOS HERE
LINK=(
'Title for the video link'
'https://vids.net/ABCAED/AADDCDE/m3u8/AADDCDE/AADDCDE'
'Title for the next video'
'https://vids.net/EECEADFE/EECEADFE/m3u8/EECEADFE/EECEADFE'
)

# ------------------------------------------------------------------------------
mkdir "$GROUP"
cd "$GROUP"

I=0
while [ $I -lt ${#LINK[@]} ]
do
  # create folder for streaming media
  TITLE=${LINK[$I]}
  mkdir "$TITLE"
  cd "$TITLE"
  mkdir 'parts'
  cd 'parts'

  J=$((I + 1))
  URL=${LINK[$J]}

  I=$((I + 2))

  DIR="${URL##*/}"

  # download all streaming media parts
  VID=-1
  while [ $? -eq 0 ];
  do
    VID=$((VID + 1))
    wget $URL'_'$VID.ts
  done

  # combine parts
  COUNTER=0
  while [  $COUNTER -lt $VID ]; do
    echo $DIR'_'$COUNTER.ts | tr " " "\n" >> tslist
    let COUNTER=COUNTER+1
  done
  while read line; do cat $line >> $TITLE.ts; done < tslist

  rm -rf tslist
  mv "$TITLE.ts" "../$TITLE.ts"

  cd ..
  rm -rf 'parts'
  cd ..

done

You cannot load images directly with @2x or @3x, system selects appropriate image automatically, just specify the name using UIImage:

UIImage(named: "green-square-Retina")

In C++, your source files are usually parsed from top to bottom in a single pass, so any variable or function must be declared before they can be used. There are some exceptions to this, like when defining functions inline in a class definition, but that's not the case for your code.

Either move the definition of integrate above the one for getSkewNormal, or add a forward declaration above getSkewNormal:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

The same applies for sum.

Try this:

grep -rl 'SearchString' ./ | xargs sed -i 's/REPLACESTRING/WITHTHIS/g'

grep -rl will recursively search for the SEARCHSTRING in the directories ./ and will replace the strings using sed.

Ex:

Replacing a name TOM with JERRY using search string as SWATKATS in directory CARTOONNETWORK

grep -rl 'SWATKATS' CARTOONNETWORK/ | xargs sed -i 's/TOM/JERRY/g'

This will replace TOM with JERRY in all the files and subdirectories under CARTOONNETWORK wherever it finds the string SWATKATS.

The modern approach is to move away from VBA for important code, and write a .NET managed Add-In using c# or vb.net, there are a lot of resources for this on the www, and you could use the Express version of MS Visual Studio

Matplotlib uses a dictionary from its colors.py module.

To print the names use:

# python2:

import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
    print(name, hex)

# python3:

import matplotlib
for name, hex in matplotlib.colors.cnames.items():
    print(name, hex)

This is the complete dictionary:

You could plot them like this:

import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.colors as colors
import math


fig = plt.figure()
ax = fig.add_subplot(111)

ratio = 1.0 / 3.0
count = math.ceil(math.sqrt(len(colors.cnames)))
x_count = count * ratio
y_count = count / ratio
x = 0
y = 0
w = 1 / x_count
h = 1 / y_count

for c in colors.cnames:
    pos = (x / x_count, y / y_count)
    ax.add_patch(patches.Rectangle(pos, w, h, color=c))
    ax.annotate(c, xy=pos)
    if y >= y_count-1:
        x += 1
        y = 0
    else:
        y += 1

plt.show()

Try

if( this["person_data[document_type]"].value != '') { _x000D_
  console.log('not empty');_x000D_
}

<input id="person_data[document_type]" value="test" />

For closing cmd window, especially after ending weblogic or JBOSS app servers console with Ctrl+C, I'm using 'call' command instead of 'start' in my batch files. My startWLS.cmd file then looks like:

call [BEA_HOME]\user_projects\domains\test_domain\startWebLogic.cmd

After Ctrl+C(and 'Y' answer) cmd window is automatically closed.

You just need to make sure you have the rights to push to the remote repository and do

git push origin master

or simply

git push

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

In Boost.Test there is the --auto_start_dbg parameter for breaking into the debugger when a test fails (on an exception or on an assertion failure). For some reason it doesn't work for me.

See http://www.boost.org/doc/libs/1_40_0/libs/test/doc/html/utf/usage-recommendations/dot-net-specific.html

For this reason I have created my custom test_observer that will break into the debugger when there is an assertion failure or an exception. This is enabled on debug builds when we are running under a debugger.

In one of the source files of my unit test EXE file I have added this code:

#ifdef _DEBUG

#include <boost/test/framework.hpp>
#include <boost/test/test_observer.hpp>

struct BoostUnitTestCrtBreakpointInDebug: boost::unit_test::test_observer
{
    BoostUnitTestCrtBreakpointInDebug()
    {
        boost::unit_test::framework::register_observer(*this);
    }

    virtual ~BoostUnitTestCrtBreakpointInDebug()
    {
        boost::unit_test::framework::deregister_observer(*this);
    }

    virtual void assertion_result( bool passed /* passed */ )
    {
        if (!passed)
            BreakIfInDebugger();
    }

    virtual void exception_caught( boost::execution_exception const& )
    {
        BreakIfInDebugger();
    }

    void BreakIfInDebugger()
    {
        if (IsDebuggerPresent())
        {
            /**
             * Hello, I know you are here staring at the debugger :)
             *
             * If you got here then there is an exception in your unit
             * test code. Walk the call stack to find the actual cause.
             */
            _CrtDbgBreak();
        }
    }
};

BOOST_GLOBAL_FIXTURE(BoostUnitTestCrtBreakpointInDebug);

If you decorate the User class with the XmlType to match the required capitalization:

[XmlType("user")]
public class User
{
   ...
}

Then the XmlRootAttribute on the XmlSerializer ctor can provide the desired root and allow direct reading into List<>:

    // e.g. my test to create a file
    using (var writer = new FileStream("users.xml", FileMode.Create))
    {
        XmlSerializer ser = new XmlSerializer(typeof(List<User>),  
            new XmlRootAttribute("user_list"));
        List<User> list = new List<User>();
        list.Add(new User { Id = 1, Name = "Joe" });
        list.Add(new User { Id = 2, Name = "John" });
        list.Add(new User { Id = 3, Name = "June" });
        ser.Serialize(writer, list);
    }

...

    // read file
    List<User> users;
    using (var reader = new StreamReader("users.xml"))
    {
        XmlSerializer deserializer = new XmlSerializer(typeof(List<User>),  
            new XmlRootAttribute("user_list"));
        users = (List<User>)deserializer.Deserialize(reader);
    }

Try to use datepicker/ timepicker instead of datetimepicker like:

replace:

$('#datetimepicker1').datetimepicker();

with:

$('#datetimepicker1').datepicker(); // or timepicker for time picker

The codes above wouldn't work in Excel 2010 My code bellow allows you to go through number of sheets you would like then select tables and delete rows

Sub DeleteTableRows()
Dim table As ListObject
Dim SelectedCell As Range
Dim TableName As String
Dim ActiveTable As ListObject

'select ammount of sheets want to this to run
For i = 1 To 3
    Sheets(i).Select
    Range("A1").Select
    Set SelectedCell = ActiveCell
    Selection.AutoFilter

    'Determine if ActiveCell is inside a Table
    On Error GoTo NoTableSelected
    TableName = SelectedCell.ListObject.Name
    Set ActiveTable = ActiveSheet.ListObjects(TableName)
    On Error GoTo 0

    'Clear first Row
    ActiveTable.DataBodyRange.Rows(1).ClearContents
    'Delete all the other rows `IF `they exist
    On Error Resume Next
    ActiveTable.DataBodyRange.Offset(1, 0).Resize(ActiveTable.DataBodyRange.Rows.Count - 1, _
    ActiveTable.DataBodyRange.Columns.Count).Rows.Delete
    Selection.AutoFilter
    On Error GoTo 0
Next i
Exit Sub
'Error Handling
NoTableSelected:
  MsgBox "There is no Table currently selected!", vbCritical

End Sub

In addition to running it with mvn exec:java, you can also run it with mvn exec:exec

mvn exec:exec -Dexec.executable="java" -Dexec.args="-classpath %classpath your.package.MainClass"

I have not used Bootstrap but I worked on Zurb Foundation. On that I used to add space like this.

<div id="main" class="container" role="main">
    <div class="row">

        <div class="span5 offset1">
            <h2>Welcome</h2>
            <p>Hello and welcome to my website.</p>
        </div>
        <div class="span6">
            Image Here (TODO)
        </div>
    </div>

Visit this link: http://getbootstrap.com/2.3.2/scaffolding.html and read the section: Offsetting columns.

I think I know what you are doing wrong. If you are applying padding to the span6 like this:

<div class="span6" style="padding-left:5px;">
    <h2>Welcome</h2>
    <p>Hello and welcome to my website.</p>
</div>

It is wrong. What you have to do is add padding to the elements inside:

<div class="span6">
    <h2 style="padding-left:5px;">Welcome</h2>
    <p  style="padding-left:5px;">Hello and welcome to my website.</p>
</div>

You can add to the system-path at runtime:

import sys
sys.path.insert(0, 'path/to/your/py_file')

import py_file

This is by far the easiest way to do it.

git add puts pending files to the so called git 'index' which is local.

After that you use git commit to commit (apply) things in the index.

Then use git push [remotename] [localbranch][:remotebranch] to actually push them to a remote repository.

This helped me: Print page without links

@media print {
    a[href]:after {
        content: none !important;
    }
}

Whenever changes are made in dockerfile or compose or requirements , re-Run it using docker-compose up --build . So that images get rebuild and refreshed

Well, I'm late.

In your image, the paper is white, while the background is colored. So, it's better to detect the paper is Saturation(???) channel in HSV color space. Take refer to wiki HSL_and_HSV first. Then I'll copy most idea from my answer in this Detect Colored Segment in an image.

Main steps:

1. Read into BGR
2. Convert the image from bgr to hsv space
3. Threshold the S channel
4. Then find the max external contour(or do Canny, or HoughLines as you like, I choose findContours), approx to get the corners.

This is my result:

The Python code(Python 3.5 + OpenCV 3.3):

#!/usr/bin/python3
# 2017.12.20 10:47:28 CST
# 2017.12.20 11:29:30 CST

import cv2
import numpy as np

##(1) read into  bgr-space
img = cv2.imread("test2.jpg")

##(2) convert to hsv-space, then split the channels
hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
h,s,v = cv2.split(hsv)

##(3) threshold the S channel using adaptive method(`THRESH_OTSU`) or fixed thresh
th, threshed = cv2.threshold(s, 50, 255, cv2.THRESH_BINARY_INV)

##(4) find all the external contours on the threshed S
#_, cnts, _ = cv2.findContours(threshed, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
cnts = cv2.findContours(threshed, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)[-2]

canvas  = img.copy()
#cv2.drawContours(canvas, cnts, -1, (0,255,0), 1)

## sort and choose the largest contour
cnts = sorted(cnts, key = cv2.contourArea)
cnt = cnts[-1]

## approx the contour, so the get the corner points
arclen = cv2.arcLength(cnt, True)
approx = cv2.approxPolyDP(cnt, 0.02* arclen, True)
cv2.drawContours(canvas, [cnt], -1, (255,0,0), 1, cv2.LINE_AA)
cv2.drawContours(canvas, [approx], -1, (0, 0, 255), 1, cv2.LINE_AA)

## Ok, you can see the result as tag(6)
cv2.imwrite("detected.png", canvas)

You are trying to pass pointers (which you do not delete, thus leaking memory) where references are needed. You do not really need pointers here:

Complex firstComplexNumber(81, 93);
Complex secondComplexNumber(31, 19);

cout << "Numarul complex este: " << firstComplexNumber << endl;
//                                  ^^^^^^^^^^^^^^^^^^ No need to dereference now

// ...

Complex::distanta(firstComplexNumber, secondComplexNumber);

If you are using a command to just call curl like that, you can do the same thing in Python with subprocess. Example:

subprocess.call(['curl', '-i', '-H', '"Accept: application/xml"', '-u', 'login:key', '"https://app.streamsend.com/emails"'])

Or you could try PycURL if you want to have it as a more structured api like what PHP has.

The required file can be accessed as below from resource folder in scala

val file = scala.io.Source.fromFile(s"src/main/resources/app.config").getLines().mkString

ErrorResponse is your custom response object

Kotlin

val gson = Gson()
val type = object : TypeToken<ErrorResponse>() {}.type
var errorResponse: ErrorResponse? = gson.fromJson(response.errorBody()!!.charStream(), type)

Java

Gson gson = new Gson();
Type type = new TypeToken<ErrorResponse>() {}.getType();
ErrorResponse errorResponse = gson.fromJson(response.errorBody.charStream(),type);

You have to close all tags like , etc for this to not show.

1. Create new project in Android studio;

2. Press Ctrl+Shift+Alt+S

3. Proceed to "Project" section

4. You can see actual gradle version and android pluging version. Copy that to your project.

Do not use '*' for Origin, until You really need a completely public behavior.
As Wikipedia says:

"The value of "*" is special in that it does not allow requests to supply credentials, meaning HTTP authentication, client-side SSL certificates, nor does it allow cookies to be sent."

That means, you'll get a lot of errors, especially in Chrome when you'll try to implement for example a simple authentication.

Here is a corrected wrapper:

// Code has not been tested.
func addDefaultHeaders(fn http.HandlerFunc) http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        if origin := r.Header.Get("Origin"); origin != "" {
            w.Header().Set("Access-Control-Allow-Origin", origin)
        }
        w.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
        w.Header().Set("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token")
        w.Header().Set("Access-Control-Allow-Credentials", "true")
        fn(w, r)
    }
}

And don't forget to reply all these headers to the preflight OPTIONS request.

del parentpath (or just place the .bat file inside parent folder) *.txt /s

That will delete all .txt files in the parent and all sub folders. If you want to delete multiple file extensions just add a space and do the same thing. Ex. *.txt *.dll *.xml

For example 1 and 2 you need to create static methods:

public static string InstanceMethod() {return "Hello World";}

Then for example 3 you need an instance of your object to invoke the method:

object o = new object();
string s = o.InstanceMethod();

You have to enable Type Name Handling and pass that to the (de)serializer as a settings parameter.

Base object1 = new Base() { Name = "Object1" };
Derived object2 = new Derived() { Something = "Some other thing" };
List<Base> inheritanceList = new List<Base>() { object1, object2 };

JsonSerializerSettings settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
string Serialized = JsonConvert.SerializeObject(inheritanceList, settings);
List<Base> deserializedList = JsonConvert.DeserializeObject<List<Base>>(Serialized, settings);

This will result in correct deserialization of derived classes. A drawback to it is that it will name all the objects you are using, as such it will name the list you are putting the objects in.

Yes, in AndroidManifest.xml, declare your Activity like so: <activity ... android:screenOrientation="landscape" .../>
