There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

If all you want to do is calculate the sum of 1,2,3... n then you could use :

 int sum = (n * (n + 1)) / 2;

The following will give you an array of the type you want while preserving type safety.

PCB[] getAll(Class<PCB[]> arrayType) {  
    PCB[] res = arrayType.cast(java.lang.reflect.Array.newInstance(arrayType.getComponentType(), list.size()));  
    for (int i = 0; i < res.length; i++)  {  
        res[i] = list.get(i);  
    }  
    list.clear();  
    return res;  
}

How this works is explained in depth in my answer to the question that Kirk Woll linked as a duplicate.

Using IIF(RowNumber...) can lead to some issues when rows are being grouped and another alternative is to use a simple VBScript function to determine the color.

It's a little more effort but when the basic solution does not suffice, it's a nice alternative.

Basically, you add code to the Report as follows...

Private bOddRow As Boolean
'*************************************************************************
' -- Display green-bar type color banding in detail rows
' -- Call from BackGroundColor property of all detail row textboxes
' -- Set Toggle True for first item, False for others.
'*************************************************************************
Function AlternateColor(ByVal OddColor As String, _
         ByVal EvenColor As String, ByVal Toggle As Boolean) As String
    If Toggle Then bOddRow = Not bOddRow
    If bOddRow Then
        Return OddColor
    Else
        Return EvenColor
    End If
End Function

Then on each cell, set the BackgroundColor as follows:

=Code.AlternateColor("AliceBlue", "White", True)

I had this problem and just decided to rename one of the programs from python.exe to python2.7.exe. Now I can specify on command prompt which program to run easily without introducing any scripts or changing environmental paths. So i have two programs: python2.7 and python (the latter which is v.3.8 aka default).

Send your file as a base64 string.

 var element = angular.element('<a/>');
                         element.attr({
                             href: 'data:attachment/csv;charset=utf-8,' + encodeURI(atob(response.payload)),
                             target: '_blank',
                             download: fname
                         })[0].click();

If attr method not working in Firefox You can also use javaScript setAttribute method

If you want vertical sizing proportional to a width set in pixels on an enclosing div, I believe you need an extra element, like so:

#html

<div class="ptest">
    <div class="ptest-wrap">
        <div class="ptest-inner">
            Put content here
        </div>
    </div>
</div>

#css
.ptest {
  width: 200px;
  position: relative;
}

.ptest-wrap {
    padding-top: 60%;
}
.ptest-inner {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background: #333;
}

Here's the 2 div solution that doesn't work. Note the 60% vertical padding is proportional to the window width, not the div.ptest width:

Here's the example with the code above, which does work:

I have a longer test to try. This takes an average of 160 ns to read each line as add it to a List (Which is likely to be what you intended as dropping the newlines is not very useful.

public static void main(String... args) throws IOException {
    final int runs = 5 * 1000 * 1000;

    final ServerSocket ss = new ServerSocket(0);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Socket serverConn = ss.accept();
                String line = "Hello World!\n";
                BufferedWriter br = new BufferedWriter(new OutputStreamWriter(serverConn.getOutputStream()));
                for (int count = 0; count < runs; count++)
                    br.write(line);
                serverConn.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();

    Socket conn = new Socket("localhost", ss.getLocalPort());

    long start = System.nanoTime();
    BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;

    List<String> responseData = new ArrayList<String>();
    while ((line = in.readLine()) != null) {
        responseData.add(line);
    }
    long time = System.nanoTime() - start;
    System.out.println("Average time to read a line was " + time / runs + " ns.");
    conn.close();
    ss.close();
}

prints

Average time to read a line was 158 ns.

If you want to build a StringBuilder, keeping newlines I would suggets the following approach.

Reader r = new InputStreamReader(conn.getInputStream());
String line;

StringBuilder sb = new StringBuilder();
char[] chars = new char[4*1024];
int len;
while((len = r.read(chars))>=0) {
    sb.append(chars, 0, len);
}

Still prints

Average time to read a line was 159 ns.

In both cases, the speed is limited by the sender not the receiver. By optimising the sender, I got this timing down to 105 ns per line.

I use this script in my extension "Grab Any Media" and work fine ( like youtube case )

var oldHref = document.location.href;

window.onload = function() {

    var
         bodyList = document.querySelector("body")

        ,observer = new MutationObserver(function(mutations) {

            mutations.forEach(function(mutation) {

                if (oldHref != document.location.href) {

                    oldHref = document.location.href;

                    /* Changed ! your code here */

                }

            });

        });

    var config = {
        childList: true,
        subtree: true
    };

    observer.observe(bodyList, config);

};

What are the target browsers? Different browsers set different default CSS rules. Try including a CSS reset, such as the meyerweb CSS reset or normalize.css, to remove those defaults. Google "CSS reset vs normalize" to see the differences.

In modern versions of jQuery, you would use the $._data method to find any events attached by jQuery to the element in question. Note, this is an internal-use only method:

// Bind up a couple of event handlers
$("#foo").on({
    click: function(){ alert("Hello") },
    mouseout: function(){ alert("World") }
});

// Lookup events for this particular Element
$._data( $("#foo")[0], "events" );

The result from $._data will be an object that contains both of the events we set (pictured below with the mouseout property expanded):

Then in Chrome, you may right click the handler function and click "view function definition" to show you the exact spot where it is defined in your code.

Here's a function that is also based on cloneNode, but with an option to clone only the parent node and move all the children (to preserve their event listeners):

function recreateNode(el, withChildren) {
  if (withChildren) {
    el.parentNode.replaceChild(el.cloneNode(true), el);
  }
  else {
    var newEl = el.cloneNode(false);
    while (el.hasChildNodes()) newEl.appendChild(el.firstChild);
    el.parentNode.replaceChild(newEl, el);
  }
}

Remove event listeners on one element:

recreateNode(document.getElementById("btn"));

Remove event listeners on an element and all of its children:

recreateNode(document.getElementById("list"), true);

If you need to keep the object itself and therefore can't use cloneNode, then you have to wrap the addEventListener function and track the listener list by yourself, like in this answer.

Here is a quick easy way to just get the name of the url.

            var urlHost = HttpContext.Current.Request.Url.Host;

            var xUrlHost = urlHost.Split('.');
            foreach(var thing in xUrlHost)
            {
                if(thing != "www" && thing != "com")
                {
                    urlHost = thing;
                }
            }

You are trying to assign to literal integer values. 1, 2, etc. are not valid names; they are only valid integers:

>>> 1
1
>>> 1 = 'something'
  File "<stdin>", line 1
SyntaxError: can't assign to literal

You probably want to use a list or dictionary instead:

names = []
for i in range(1, 6):
    name = input("Please enter name {}:".format(i))
    names.append(name)

Using a list makes it much easier to pick a random value too:

winner = random.choice(names)
print('Well done {}. You are the winner!'.format(winner))

Update 2020: how they made it work while avoiding XSS attacks

GitHub appears to use two security approaches, this is a good article: https://digi.ninja/blog/svg_xss.php see also: https://security.stackexchange.com/questions/148507/how-to-prevent-xss-in-svg-file-upload

• show SVG inside <img tag, which prevents scripts from running, e.g. on READMEs: https://github.com/cirosantilli/test-git-web-interface/tree/8e394cdb012cba4bcf55ebdb89f36872b4c6c12a

• use Content-Security-Policy: default-src 'none'; style-src 'unsafe-inline'; sandbox. This prevents the script from running even in raw which contains the raw SVG file: https://raw.githubusercontent.com/cirosantilli/test-git-web-interface/8e394cdb012cba4bcf55ebdb89f36872b4c6c12a/svg-foreignObject.svg

  You can see the header with curl -vvv. The regular github.com pages also have a content-security-policy, but it is much larger.

Update 2017

A GitHub dev is currently looking into this: https://github.com/github/markup/issues/556#issuecomment-306103203

Update 2014-12: GitHub now renders SVG on blob show, so I don't see any reason why not to render on README renderings:

• https://github.com/blog/1902-svg-viewing-diffing
• https://github.com/cirosantilli/test/blob/2144a93333be144152e8b0d4144b77b211afce63/svg.svg

Also note that that SVG does have an XSS attempt but it does not run: https://raw.githubusercontent.com/cirosantilli/test/2144a93333be144152e8b0d4144b77b211afce63/svg.svg

The billion laugh SVG does make Firefox 44 Freeze, but Chromium 48 is OK: https://github.com/cirosantilli/web-cheat/blob/master/svg-billion-laughs.svg

Petah mentioned that blobs are fine because the SVG is inside an iframe.

Possible rationale for GitHub not serving SVG images

• general XML vulnerabilities. E.g. opening a billion laughs exploit just made Firefox crash my system. Firefox bug with exploit attached: https://bugzilla.mozilla.org/page.cgi?id=voting/user.html. Same on Chromium: https://code.google.com/p/chromium/issues/detail?id=231562

• SVG XSS scripting: while most browsers don't run scripts when the SVG is embedded with img, it seems that this is not required by the standards, so maybe GitHub is playing it safe.

  Browsers do run it if you open the SVG directly (but it appears that GitHub never shows images directly on the github.com domain) or if it is inline (which are currently completely removed by GitHub), so those cases shouldn't be a security concern. Relevant links:

  • spec: http://www.w3.org/TR/SVG/script.html
  • interactive SVG demo: http://www.w3.org/TR/SVG/images/script/script01.svg

The following questions asks about the risks of SVG in general: https://security.stackexchange.com/questions/11384/exploits-or-other-security-risks-with-svg-upload

i leaned that from a video on udemy and edited to be stronger random password

}

private String pass() {
        String passswet="1234567890zxcvbbnmasdfghjklop[iuytrtewq@#$%^&*" ;

        char icon1;
        char[] t=new char[20];

         int rand1=(int)(Math.random()*6)+38;//to make a random within the range of special characters

            icon1=passswet.charAt(rand1);//will produce char with a special character

        int i=0;
        while( i <11) {

             int rand=(int)(Math.random()*passswet.length());
             //notice (int) as the original value of Math>random() is double

             t[i] =passswet.charAt(rand);

             i++;
                t[10]=icon1;
//to replace the specified item with icon1
         }
        return new String(t);
}






}

The OnChange event is a good choice. But if a user select the same image, the event will not be triggered because the current value is the same as the previous.

The image is the same with a width changed, for example, and it should be uploaded to the server.

To prevent this problem you could to use the following code:

$(document).ready(function(){
    $("input[type=file]").click(function(){
        $(this).val("");
    });

    $("input[type=file]").change(function(){
        alert($(this).val());
    });
});

The variable objectSummary holds the current object of type S3ObjectSummary returned from the objectListing.getObjectSummaries() and iterate over the collection.

Here is an example of this enhanced for loop from Java Tutorials

class EnhancedForDemo {
 public static void main(String[] args){
      int[] numbers = {1,2,3,4,5,6,7,8,9,10};
      for (int item : numbers) {
        System.out.println("Count is: " + item);
      }
 }
}

In this example, the variable item holds the current value from the numbers array.

Output is as follows:

Count is: 1
Count is: 2
Count is: 3
Count is: 4
Count is: 5
Count is: 6
Count is: 7
Count is: 8
Count is: 9
Count is: 10

Hope this helps !

C# has a few more features than Java. Take delegates for example: Many very simple C# applications use delegates, while the Java folks figures that the observer pattern was sufficient. So, in order for a tool to convert a C# application which uses delegates it would have to translate the structure from using delegates to an implementation of the observer pattern. Another problem is the fact that C# methods are not virtual by default while Java methods are. Additionally, Java doesn't have a way to make methods non virtual. This creates another problem: an application in C# could leverage non virtual method behavior through polymorphism in a way the does not translate directly to Java. If you look around you will probably find that there are lots of tools to convert Java to C# since it is a simpler language (please don't flame me I didn't say worse I said simpler); however, you will find very few if any decent tools that convert C# to Java.

I would recommend changing your approach to converting from Java to C# as it will create fewer headaches in the long run. Db4Objects recently released their internal tool which they use to convert Db4o into C# to the public. It is called Sharpen. If you register with their site you can view this link with instructions on how to use Sharpen: http://developer.db4o.com/Resources/view.aspx/Reference/Sharpen/How_To_Setup_Sharpen

(I've been registered with them for a while and they're good about not spamming)

Git keeps all of its files in the .git directory. Just remove that one and init again.

This post well show you how to find the hide .git file on Windows, Mac OSX, Ubuntu

for (var key in data) {
    alert("User " + data[key] + " is #" + key); // "User john is #234"
}

Just for reference, if you are using:

 $(el).offset().top 

To get the position, it can be affected by the position of the parent element. Thus you may want to be consistent and use the following to set it:

$(el).offset({top: pos});

As opposed to the CSS methods above.

The official list of current iOS Wi-Fi Management APIs

There is no Wi-Fi Direct type of connection available. The primary issue being that Apple does not allow programmatic setting of the Wi-Fi network SSID and password. However, this improves substantially in iOS 11 where you can at least prompt the user to switch to another WiFi network.

QA1942 - iOS Wi-Fi Management APIs

Entitlement option

This technology is useful if you want to provide a list of Wi-Fi networks that a user might want to connect to in a manager type app. It requires that you apply for this entitlement with Apple and the email address is in the documentation.

• NEHotspotHelper

MFi Program options

These technologies allow the accessory connect to the same network as the iPhone and are not for setting up a peer-to-peer connection.

• Wireless Accessory Configuration (WAC)
• HomeKit

Peer-to-peer between Apple devices

These APIs come close to what you want, but they're Apple-to-Apple only.

• NSNetService
• Multipeer Connectivity

Brought up at WWDC 2017 Advances in Networking, Part 1 is NEHotspotConfiguration which allows the app to specify and prompt to connect to a specific network.

In my opinion, the main difference between both mechanisms is that sleep/interrupt is the most basic way of handling threads, whereas wait/notify is an abstraction aimed to do thread inter-communication easier. This means that sleep/interrupt can do anything, but that this specific task is harder to do.

Why is wait/notify more suitable? Here are some personal considerations:

1. It enforces centralization. It allows to coordinate the communication between a group of threads with a single shared object. This simplifies the work a lot.

2. It enforces synchronization. Because it makes the programmer wrap the call to wait/notify in a synchronized block.

3. It's independent of the thread origin and number. With this approach you can add more threads arbitrarily without editing the other threads or keeping a track of the existing ones. If you used sleep/interrupt, first you would need to keep the references to the sleeping threads, and then interrupt them one by one, by hand.

An example from the real life that is good to explain this is a classic restaurant and the method that the personnel use to communicate among them: The waiters leave the customer requests in a central place (a cork board, a table, etc.), ring a bell, and the workers from the kitchen come to take such requests. Once that there is any course ready, the kitchen personnel ring the bell again so that the waiters are aware and take them to the customers.

std::copy cannot be used to insert into an empty container. To do that, you need to use an insert_iterator like so:

std::set<double> input;
input.insert(5);
input.insert(6);

std::vector<double> output;
std::copy(input.begin(), input.end(), inserter(output, output.begin())); 

Yes, you should configure $locationProvider and set html5Mode to true:

angular.module('phonecat', []).
  config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {

    $routeProvider.
      when('/phones', {templateUrl: 'partials/phone-list.html',   controller: PhoneListCtrl}).
      when('/phones/:phoneId', {templateUrl: 'partials/phone-detail.html', controller: PhoneDetailCtrl}).
      otherwise({redirectTo: '/phones'});

    $locationProvider.html5Mode(true);

  }]);

Linting is a process by a linter program that analyzes source code in a particular programming language and flag potential problems like syntax errors, deviations from a prescribed coding style or using constructs known to be unsafe.

For example, a JavaScript linter would flag the first use of parseInt below as unsafe:

// without a radix argument - Unsafe
var count = parseInt(countString);

// with a radix paremeter specified - Safe
var count = parseInt(countString, 10);

HashMap basically contains Entry which subsequently contains Key(Object) and Value(Object).Internally HashSet are HashMap and HashMap do replace values as some of you already pointed..but does it really replaces the keys???No ..and that is the trick here. HashMap keeps its value as key in the underlying HashMap and value is just a dummy object.So if u try to reinsert same Value in HashMap(Key in underlying Map).It just replaces the dummy value and not the Key(Value for HashSet).

Look at the below code for HashSet Class:

public boolean  [More ...] add(E e) {

   return map.put(e, PRESENT)==null;
}

Here e is the value for HashSet but key for underlying map.and key is never replaced. Hope i am able to clear the confusion.

define changed props in mapStateToProps of connect method in child component.

function mapStateToProps(state) {
  return {
    chanelList: state.messaging.chanelList,
  };
}

export default connect(mapStateToProps)(ChannelItem);

In my case, channelList's channel is updated so I added chanelList in mapStateToProps

You cannot get a generic parameter from a variable. But you can from a method or field declaration:

Method method = getClass().getDeclaredMethod("chill", List.class);
Type[] params = method.getGenericParameterTypes();
ParameterizedType firstParam = (ParameterizedType) params[0];
Type[] paramsOfFirstGeneric = firstParam.getActualTypeArguments();

If you don't mind importing the json module, then the best way to handle it is through json.JSONDecodeError (or json.decoder.JSONDecodeError as they are the same) as using default errors like ValueError could catch also other exceptions not necessarily connected to the json decode one.

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want

//EDIT (Oct 2020):

As @Jacob Lee noted in the comment, there could be the basic common TypeError raised when the JSON object is not a str, bytes, or bytearray. Your question is about JSONDecodeError, but still it is worth mentioning here as a note; to handle also this situation, but differentiate between different issues, the following could be used:

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want
except TypeError as e:
    # do whatever you want in this case

In a nutshell, the syntax for Bower version numbers (and NPM's) is called SemVer, which is short for 'Semantic Versioning'. You can find documentation for the detailed syntax of SemVer as used in Bower and NPM on the API for the semver parser within Node/npm. You can learn more about the underlying spec (which does not mention ~ or other syntax details) at semver.org.

There's a super-handy visual semver calculator you can play with, making all of this much easier to grok and test.

SemVer isn't just a syntax! It has some pretty interesting things to say about the right ways to publish API's, which will help to understand what the syntax means. Crucially:

Once you identify your public API, you communicate changes to it with specific increments to your version number. Consider a version format of X.Y.Z (Major.Minor.Patch). Bug fixes not affecting the API increment the patch version, backwards compatible API additions/changes increment the minor version, and backwards incompatible API changes increment the major version.

So, your specific question about ~ relates to that Major.Minor.Patch schema. (As does the related caret operator ^.) You can use ~ to narrow the range of versions you're willing to accept to either:

• subsequent patch-level changes to the same minor version ("bug fixes not affecting the API"), or:
• subsequent minor-level changes to the same major version ("backwards compatible API additions/changes")

For example: to indicate you'll take any subsequent patch-level changes on the 1.2.x tree, starting with 1.2.0, but less than 1.3.0, you could use:

"angular": "~1.2"
  or:
"angular": "~1.2.0"

This also gets you the same results as using the .x syntax:

"angular": "1.2.x"

But, you can use the tilde/~ syntax to be even more specific: if you're only willing to accept patch-level changes starting with 1.2.4, but still less than 1.3.0, you'd use:

"angular": "~1.2.4"

Moving left, towards the major version, if you use...

"angular": "~1"

... it's the same as...

"angular": "1.x"
  or:
"angular": "^1.0.0"

...and matches any minor- or patch-level changes above 1.0.0, and less than 2.0:

Note that last variation above: it's called a 'caret range'. The caret looks an awful lot like a >, so you'd be excused for thinking it means "any version greater than 1.0.0". (I've certainly slipped on that.) Nope!

Caret ranges are basically used to say that you care only about the left-most significant digit - usually the major version - and that you'll permit any minor- or patch-level changes that don't affect that left-most digit. Yet, unlike a tilde range that specifies a major version, caret ranges let you specify a precise minor/patch starting point. So, while ^1.0.0 === ~1, a caret range such as ^1.2.3 lets you say you'll take any changes >=1.2.3 && <2.0.0. You couldn't do that with a tilde range.

That all seems confusing at first, when you look at it up-close. But zoom out for a sec, and think about it this way: the caret simply lets you say that you're most concerned about whatever significant digit is left-most. The tilde lets you say you're most concerned about whichever digit is right-most. The rest is detail.

It's the expressive power of the tilde and the caret that explains why people use them much more than the simpler .x syntax: they simply let you do more. That's why you'll see the tilde used often even where .x would serve. As an example, see npm itself: its own package.json file includes lots of dependencies in ~2.4.0 format, rather than the 2.4.x format it could use. By sticking to ~, the syntax is consistent all the way down a list of 70+ versioned dependencies, regardless of which beginning patch number is acceptable.

Anyway, there's still more to SemVer, but I won't try to detail it all here. Check it out on the node semver package's readme. And be sure to use the semantic versioning calculator while you're practicing and trying to get your head around how SemVer works.

RE: Non-Consecutive Version Numbers: OP's final question seems to be about specifying non-consecutive version numbers/ranges (if I have edited it fairly). Yes, you can do that, using the common double-pipe "or" operator: ||. Like so:

"angular": "1.2 <= 1.2.9 || >2.0.0"

I had this problem today. I fixed it being being explict about my require

gem 'uglifier', '>= 1.0.3', require: 'uglifier'

I had mine still in the assets group.

No, that's pretty much it. In theory you could use visibility: collapse on some <col>?s to do it, but browser support isn't all there.

To improve what you've got slightly, you could use table-layout: fixed on the <table> to allow the browser to use the simpler, faster and more predictable fixed-table-layout algorithm. You could also drop the .show rules as when a cell isn't made display: none by a .hide rule it will automatically be display: table-cell. Allowing table display to revert to default rather than setting it explicitly avoids problems in IE<8, where the table display values are not supported.

Templates. I think that is Smarty syntax.

My favourite way, in one line!

debug_backtrace()[1]['function'];

You can use it like this:

echo 'The calling function: ' . debug_backtrace()[1]['function'];

Note that this is only compatible with versions of PHP released within the last year. But it's a good idea to keep your PHP up to date anyway for security reasons.

You want to know if the column is null

select * from foo where bar is null

If you want to check for some value not equal to something and the column also contains null values you will not get the columns with null in it

does not work:

select * from foo where bar <> 'value'

does work:

select * from foo where bar <> 'value' or bar is null

in Oracle (don't know on other DBMS) some people use this

select * from foo where NVL(bar,'n/a') <> 'value'

if I read the answer from tdammers correctly then in MS SQL Server this is like that

select * from foo where ISNULL(bar,'n/a') <> 'value'

in my opinion it is a bit of a hack and the moment 'value' becomes a variable the statement tends to become buggy if the variable contains 'n/a'.

$_ is the active object in the current pipeline. You've started a new pipeline with $FOLDLIST | ... so $_ represents the objects in that array that are passed down the pipeline. You should stash the FileInfo object from the first pipeline in a variable and then reference that variable later e.g.:

write-host $NEWN.Length
$file = $_
...
Move-Item $file.Name $DPATH

You can also install the required packages with Help -> Install new software...

For deleting a dynamic array in VBA use the instruction Erase.

Example:

Dim ArrayDin() As Integer    
ReDim ArrayDin(10)    'Dynamic allocation 
Erase ArrayDin        'Erasing the Array   

Hope this help!

I just read up on this question and its answers, and I feel an answer is missing.

A common way to eliminate branch prediction that I've found to work particularly good in managed languages is a table lookup instead of using a branch (although I haven't tested it in this case).

This approach works in general if:

1. it's a small table and is likely to be cached in the processor, and
2. you are running things in a quite tight loop and/or the processor can preload the data.

Background and why

From a processor perspective, your memory is slow. To compensate for the difference in speed, a couple of caches are built into your processor (L1/L2 cache). So imagine that you're doing your nice calculations and figure out that you need a piece of memory. The processor will get its 'load' operation and loads the piece of memory into cache -- and then uses the cache to do the rest of the calculations. Because memory is relatively slow, this 'load' will slow down your program.

Like branch prediction, this was optimized in the Pentium processors: the processor predicts that it needs to load a piece of data and attempts to load that into the cache before the operation actually hits the cache. As we've already seen, branch prediction sometimes goes horribly wrong -- in the worst case scenario you need to go back and actually wait for a memory load, which will take forever (in other words: failing branch prediction is bad, a memory load after a branch prediction fail is just horrible!).

Fortunately for us, if the memory access pattern is predictable, the processor will load it in its fast cache and all is well.

The first thing we need to know is what is small? While smaller is generally better, a rule of thumb is to stick to lookup tables that are <= 4096 bytes in size. As an upper limit: if your lookup table is larger than 64K it's probably worth reconsidering.

Constructing a table

So we've figured out that we can create a small table. Next thing to do is get a lookup function in place. Lookup functions are usually small functions that use a couple of basic integer operations (and, or, xor, shift, add, remove and perhaps multiply). You want to have your input translated by the lookup function to some kind of 'unique key' in your table, which then simply gives you the answer of all the work you wanted it to do.

In this case: >= 128 means we can keep the value, < 128 means we get rid of it. The easiest way to do that is by using an 'AND': if we keep it, we AND it with 7FFFFFFF; if we want to get rid of it, we AND it with 0. Notice also that 128 is a power of 2 -- so we can go ahead and make a table of 32768/128 integers and fill it with one zero and a lot of 7FFFFFFFF's.

Managed languages

You might wonder why this works well in managed languages. After all, managed languages check the boundaries of the arrays with a branch to ensure you don't mess up...

Well, not exactly... :-)

There has been quite some work on eliminating this branch for managed languages. For example:

for (int i = 0; i < array.Length; ++i)
{
   // Use array[i]
}

In this case, it's obvious to the compiler that the boundary condition will never be hit. At least the Microsoft JIT compiler (but I expect Java does similar things) will notice this and remove the check altogether. WOW, that means no branch. Similarly, it will deal with other obvious cases.

If you run into trouble with lookups in managed languages -- the key is to add a & 0x[something]FFF to your lookup function to make the boundary check predictable -- and watch it going faster.

The result of this case

// Generate data
int arraySize = 32768;
int[] data = new int[arraySize];

Random random = new Random(0);
for (int c = 0; c < arraySize; ++c)
{
    data[c] = random.Next(256);
}

/*To keep the spirit of the code intact, I'll make a separate lookup table
(I assume we cannot modify 'data' or the number of loops)*/

int[] lookup = new int[256];

for (int c = 0; c < 256; ++c)
{
    lookup[c] = (c >= 128) ? c : 0;
}

// Test
DateTime startTime = System.DateTime.Now;
long sum = 0;

for (int i = 0; i < 100000; ++i)
{
    // Primary loop
    for (int j = 0; j < arraySize; ++j)
    {
        /* Here you basically want to use simple operations - so no
        random branches, but things like &, |, *, -, +, etc. are fine. */
        sum += lookup[data[j]];
    }
}

DateTime endTime = System.DateTime.Now;
Console.WriteLine(endTime - startTime);
Console.WriteLine("sum = " + sum);
Console.ReadLine();

The classpath is the path that the system will follow when trying to find the classes that you're trying to run. In the batch file you're trying to execute it probably has a variable like CLASSPATH=blah;blah;etc or a java command that looks similar to

java -classpath "c:\directory\lib\squirrel-sql.jar" com.some.squirrel.package.file

If you can find or add that classpath setting, make sure that it includes a path to the squirrel-sql.jar and any other jar files that it may depend on separated by semicolons (or the root /lib directory that may be included with the installation).

Basically you just need to tell java where to find the class files that you're trying to execute. Wikipedia has a more indepth discussion about classpath and can offer you more insight. http://en.wikipedia.org/wiki/Classpath_(Java)

My blog has a complete series of tutorial starting from scratch for WPF MVVM and WPF Prism. Have a look here: http://blog.raffaeu.com/archive/2009/06/03/wpf-and-vmmv-tutorial-01-introduction.aspx

The following code works on both Linux and Windows, and not depending on external modules

import os
import subprocess
import platform
import re

def pid_alive(pid:int):
    """ Check For whether a pid is alive """


    system = platform.uname().system
    if re.search('Linux', system, re.IGNORECASE):
        try:
            os.kill(pid, 0)
        except OSError:
            return False
        else:
            return True
    elif re.search('Windows', system, re.IGNORECASE):
        out = subprocess.check_output(["tasklist","/fi",f"PID eq {pid}"]).strip()
        # b'INFO: No tasks are running which match the specified criteria.'

        if re.search(b'No tasks', out, re.IGNORECASE):
            return False
        else:
            return True
    else:
        raise RuntimeError(f"unsupported system={system}")

It can be easily enhanced in case you need

1. other platforms
2. other language

Here's some sample code. This worked for me.

<LinearLayout
    android:gravity="center"
    >
    <TextView
        android:layout_gravity="center"
        />
    <Button
        android:layout_gravity="center"
        />
</LinearLayout>

So you're designing the Linear Layout to place all its contents (TextView and Button) in its center, and then the TextView and Button are placed relative to the center of the Linear Layout.

The other answers do an excellent job describing what's going on, but one important "gotcha" is to make sure that whatever you pass through is indeed a reference to a function.

For instance, if you pass through a string instead of a function you'll get an error:

function function1(my_function_parameter){
    my_function_parameter();   
}

function function2(){
 alert('Hello world');   
}

function1(function2); //This will work

function1("function2"); //This breaks!

Please use if condition with while loop and try.

eg.

if ($result = $conn->query($query)) {

    /* fetch associative array */
    while ($row = $result->fetch_assoc()) {

    }
    /* free result set */
    $result->free();
}

While reading this thread, I often get the impression that people are using "UTF-8" as a synonym to "Unicode". Please make a distinction between Unicode's "Code-Points" which are an enlarged relative of the ASCII code and Unicode's various "encodings". And there are a few of them, of which UTF-8, UTF-16 and UTF-32 are the current ones and a few more are obsolete.

Please, UTF-8 (as well as all other encodings) exists and have meaning in input or in output only. Internally, since Perl 5.8.1, all strings are kept as Unicode "Code-points". True, you have to enable some features as admiringly covered previously.

(question) Don't you get that info in

select * from pg_user;

or using the view pg_stat_activity:

select * from pg_stat_activity;

Added:

the view says:

One row per server process, showing database OID, database name, process ID, user OID, user name, current query, query's waiting status, time at which the current query began execution, time at which the process was started, and client's address and port number. The columns that report data on the current query are available unless the parameter stats_command_string has been turned off. Furthermore, these columns are only visible if the user examining the view is a superuser or the same as the user owning the process being reported on.

can't you filter and get that information? that will be the current users on the Database, you can use began execution time to get all queries from last 5 minutes for example...

something like that.

for my script of python, I use...

To START python script :

start-stop-daemon --start --background --pidfile $PIDFILE --make-pidfile --exec $DAEMON

To STOP python script :

PID=$(cat $PIDFILE)
kill -9 $PID
rm -f $PIDFILE

Chrome 11 spits out the following in its debugger:

[Error] GET http://www.mypicx.com/images/logo.jpg undefined (undefined)

It looks like that hosting service is using some funky dynamic system that is preventing these browsers from fetching it correctly. (Instead it tries to fetch the default base image, which is problematically a jpeg.) Could you just upload another copy of the image elsewhere? I would expect it to be the easiest solution by a long mile.

Edit: See what happens in Chrome when you place the image using normal <img> tags ;)

I solved this by changing transports from 'websocket' to 'polling'

   var socket = io.connect('xxx.xxx.xxx.xxx:8000', {
      transports: ['polling']
   });

It's possible to change the UUID on the VDI file using the command:

 VBoxManage internalcommands sethduuid <file.vdi>

It seems this command assigns a new "random" UUID to the file. No much documentation on it, though.

You can test it by using this snipped code:

private static void Main(string[] args)
{
   int threadCount = 0;
   try
   {
      for (int i = 0; i < int.MaxValue; i ++)
      {
         new Thread(() => Thread.Sleep(Timeout.Infinite)).Start();
         threadCount ++;
      }
   }
   catch
   {
      Console.WriteLine(threadCount);
      Console.ReadKey(true);
   }
}

Beware of 32-bit and 64-bit mode of application.

@AnsgarWiechers - it's not my experience that querying everything and then pruning the result is more efficient when you're doing a targeted search of known accounts. Although, yes, it is also more efficient to select just the properties you need to return.

The below examples are based on a domain in the range of 20,000 account objects.

measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st }
...
Seconds           : 16
Milliseconds      : 208

measure-command {$userlist | get-aduser -Properties DisplayName,st}
...
Seconds           : 3
Milliseconds      : 496

In the second example, $userlist contains 368 account names (just strings, not pre-fetched account objects).

Note that if I include the where clause per your suggestion to prune to the actually desired results, it's even more expensive.

measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st |where {$userlist -Contains $_.samaccountname } }
...
Seconds           : 17
Milliseconds      : 876

Indexed attributes seem to have similar performance (I tried just returning displayName).

Even if I return all user account properties in my set, it's more efficient. (Adding a select statement to the below brings it down by a half-second).

measure-command {$userlist | get-aduser -Properties *}
...
Seconds           : 12
Milliseconds      : 75

I can't find a good document that was written in ye olde days about AD queries to link to, but you're hitting every account in your search scope to return the properties. This discusses the basics of doing effective AD queries - scoping and filtering: https://msdn.microsoft.com/en-us/library/ms808539.aspx#efficientadapps_topic01

When your search scope is "*", you're still building a (big) list of the objects and iterating through each one. An LDAP search filter is always more efficient to build the list first (or a narrow search base, which is again building a smaller list to query).

append appends a single element. extend appends a list of elements.

Note that if you pass a list to append, it still adds one element:

>>> a = [1, 2, 3]
>>> a.append([4, 5, 6])
>>> a
[1, 2, 3, [4, 5, 6]]

var result;_x000D_
result = "1,2,3".split(","); _x000D_
console.log(result);

More info on W3Schools describing the String Split function.

I thought that I might post a simpler .gitignore for anyone that is interested:

# Ignore Everything
/*

# Except for these:
!/.gitignore
!/Assets
!/Packages
!/ProjectSettings

In my case I had loaded the same *.js file on the page twice in a <script> tag, so both files were attaching event handlers to the element. I removed the duplicate declaration and that fixed the problem.

Here is an alternative solution:

class extendedWebBrowser : WebBrowser
{
    /// <summary>
    /// Default constructor which will make the browser to ignore all errors
    /// </summary>
    public extendedWebBrowser()
    {
        this.ScriptErrorsSuppressed = true;

        FieldInfo field = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
        {
             object axIWebBrowser2 = field.GetValue(this);
             axIWebBrowser2.GetType().InvokeMember("Silent", BindingFlags.SetProperty, null, axIWebBrowser2, new object[] { true });
        }
    }
}

Of all the gems I tried, show_data gem worked the best for me, I now use it extensively to log params hash in Rails pretty much all the time

One reason that the designers c# might have chosen to NOT have enums auto convert was to prevent accidentally mixing different enum types...

e.g. this is bad code followed by a good version
enum ParkingLevel { GroundLevel, FirstFloor};
enum ParkingFacing { North, East, South, West }
void Test()
{
    var parking = ParkingFacing.North; // NOT A LEVEL
    // WHOOPS at least warning in editor/compile on calls
    WhichLevel(parking); 

    // BAD  wrong type of index, no warning
    var info = ParkinglevelArray[ (int)parking ];
}


// however you can write this, looks complicated 
// but avoids using casts every time AND stops miss-use
void Test()
{
  ParkingLevelManager levels = new ParkingLevelManager();
  // assign info to each level
  var parking = ParkingFacing.North;

  // Next line wrong mixing type 
  // but great you get warning in editor or at compile time      
  var info=levels[parking];

  // and.... no cast needed for correct use
  var pl = ParkingLevel.GroundLevel;
  var infoCorrect=levels[pl];

}
class ParkingLevelInfo { /*...*/ }
class ParkingLevelManager
{
    List<ParkingLevelInfo> m_list;
    public ParkingLevelInfo this[ParkingLevel x] 
 { get{ return m_list[(int)x]; } }}

You need to either use ng-bind-html-unsafe ... or you need to include the ngSanitize module and use ng-bind-html:

with ng-bind-html-unsafe

Use this if you trust the source of the HTML you're rendering it will render the raw output of whatever you put into it.

<div><h4>Categories</h4><span ng-bind-html-unsafe="q.CATEGORY"></span></div>

OR with ng-bind-html

Use this if you DON'T trust the source of the HTML (i.e. it's user input). It will sanitize the html to make sure it doesn't include things like script tags or other sources of potential security risks.

Make sure you include this:

<script src="http://code.angularjs.org/1.0.4/angular-sanitize.min.js"></script>

Then reference it in your application module:

var app = angular.module('myApp', ['ngSanitize']);

THEN use it:

<div><h4>Categories</h4><span ng-bind-html="q.CATEGORY"></span></div>

when iserting into t-sql

this fails:

select CONVERT(datetime,'2019-09-13 09:04:35.823312',21)

this works:

select CONVERT(datetime,'2019-09-13 09:04:35.823',21)

easy way:

regexp = re.compile(r'\.(\d{6})')
def to_splunk_iso(dt):
    """Converts the datetime object to Splunk isoformat string."""
    # 6-digits string.
    microseconds = regexp.search(dt).group(1)
    return regexp.sub('.%d' % round(float(microseconds) / 1000), dt)

I found this link to be useful: css-tricks fade-in fade-out css.

Here's a summary of the csstricks post:

CSS classes:

.m-fadeOut {
  visibility: hidden;
  opacity: 0;
  transition: visibility 0s linear 300ms, opacity 300ms;
}
.m-fadeIn {
  visibility: visible;
  opacity: 1;
  transition: visibility 0s linear 0s, opacity 300ms;
}

In React:

toggle(){
    if(true condition){
        this.setState({toggleClass: "m-fadeIn"});
    }else{
        this.setState({toggleClass: "m-fadeOut"});
    }
}

render(){
    return (<div className={this.state.toggleClass}>Element to be toggled</div>)
}

for (int i = 0; i < list.length; i++) {
   if (list.get(i) .getName().equalsIgnoreCase("myName")) {
    System.out.println(i);
    break;
  }
}

You can do it like:

tvHide.setText(Html.fromHtml("<p><span style='text-decoration: underline'>Hide post</span></p>").toString());

Hope this helps

I believe you are all wrong. you need to do:

array = array[] in order to define it, and then:

array.append ["hello"] to add to it.

This is my 2nd iteration of the code. Because MemoryCache is thread safe you don't need to lock on the initial read, you can just read and if the cache returns null then do the lock check to see if you need to create the string. It greatly simplifies the code.

const string CacheKey = "CacheKey";
static readonly object cacheLock = new object();
private static string GetCachedData()
{

    //Returns null if the string does not exist, prevents a race condition where the cache invalidates between the contains check and the retreival.
    var cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

    if (cachedString != null)
    {
        return cachedString;
    }

    lock (cacheLock)
    {
        //Check to see if anyone wrote to the cache while we where waiting our turn to write the new value.
        cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

        if (cachedString != null)
        {
            return cachedString;
        }

        //The value still did not exist so we now write it in to the cache.
        var expensiveString = SomeHeavyAndExpensiveCalculation();
        CacheItemPolicy cip = new CacheItemPolicy()
                              {
                                  AbsoluteExpiration = new DateTimeOffset(DateTime.Now.AddMinutes(20))
                              };
        MemoryCache.Default.Set(CacheKey, expensiveString, cip);
        return expensiveString;
    }
}

EDIT: The below code is unnecessary but I wanted to leave it to show the original method. It may be useful to future visitors who are using a different collection that has thread safe reads but non-thread safe writes (almost all of classes under the System.Collections namespace is like that).

Here is how I would do it using ReaderWriterLockSlim to protect access. You need to do a kind of "Double Checked Locking" to see if anyone else created the cached item while we where waiting to to take the lock.

const string CacheKey = "CacheKey";
static readonly ReaderWriterLockSlim cacheLock = new ReaderWriterLockSlim();
static string GetCachedData()
{
    //First we do a read lock to see if it already exists, this allows multiple readers at the same time.
    cacheLock.EnterReadLock();
    try
    {
        //Returns null if the string does not exist, prevents a race condition where the cache invalidates between the contains check and the retreival.
        var cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

        if (cachedString != null)
        {
            return cachedString;
        }
    }
    finally
    {

        if (cachedString != null)
        {
            return cachedString;
        }

        //The entry still does not exist so we need to create it and enter the write lock
        var expensiveString = SomeHeavyAndExpensiveCalculation();

            return expensiveString;

You can use CAST() to convert from string to int. e.g. SELECT CAST('123' AS INTEGER);

Below command can be used for finding both package and current Activity name. Found this very useful command to quickly fetch these two information about an app especially when developing tests with Appium.

adb shell dumpsys window windows | grep -E 'mCurrentFocus'

Response of this command contains both package name and current Activity. For example: in following "com.android.contacts" is the package and "com.android.contacts.activities.TwelveKeyDialer" is current Activity launched on the phone which is connected via adb.

mCurrentFocus=Window{2089af8 u0 com.android.contacts/com.android.contacts.activities.TwelveKeyDialer}

Check if you have enabled "Enable just my code". If yes, disable it.

request.getParameter()

We use request.getParameter() to extract request parameters (i.e. data sent by posting a html form ). The request.getParameter() always returns String value and the data come from client.

request.getAttribute()

We use request.getAttribute() to get an object added to the request scope on the server side i.e. using request.setAttribute(). You can add any type of object you like here, Strings, Custom objects, in fact any object. You add the attribute to the request and forward the request to another resource, the client does not know about this. So all the code handling this would typically be in JSP/servlets. You can use request.setAttribute() to add extra-information and forward/redirect the current request to another resource.

For example,consider about first.jsp,

//First Page : first.jsp
<%@ page import="java.util.*" import="java.io.*"%>
<% request.setAttribute("PAGE", "first.jsp");%>
<jsp:forward page="/second.jsp"/>

and second.jsp:

<%@ page import="java.util.*" import="java.io.*"%>
From Which Page : <%=request.getAttribute("PAGE")%><br>
Data From Client : <%=request.getParameter("CLIENT")%>

From your browser, run first.jsp?CLIENT=you and the output on your browser is

From Which Page : *first.jsp*
Data From Client : you

The basic difference between getAttribute() and getParameter() is that the first method extracts a (serialized) Java object and the other provides a String value. For both cases a name is given so that its value (be it string or a java bean) can be looked up and extracted.

Lazy exceptions occur when you fetch an object typically containing a collection which is lazily loaded, and try to access that collection.

You can avoid this problem by

• accessing the lazy collection within a transaction.
• Initalizing the collection using Hibernate.initialize(obj);
• Fetch the collection in another transaction
• Use Fetch profiles to select lazy/non-lazy fetching runtime
• Set fetch to non-lazy (which is generally not recommended)

Further I would recommend looking at the related links to your right where this question has been answered many times before. Also see Hibernate lazy-load application design.

You can use the following method to keep alphanumeric characters.

replaceAll("[^a-zA-Z0-9]", "");

And if you want to keep only alphabetical characters use this

replaceAll("[^a-zA-Z]", "");

 $('#btn').click(function() {
     $('#wizard').toggle(); 
 });

if you want to begin with the div hidden, you should add style="display:none;", like this:

<div style="display:none;"> </div>

You can also try this :

JFileChooser c= new JFileChooser();
c.showOpenDialog(c);
File write_file = c.getSelectedFile();
String Content = "Writing into file"; //what u would like to append to the file



try 
{
    RandomAccessFile raf = new RandomAccessFile(write_file, "rw");
    long length = raf.length();
    //System.out.println(length);
    raf.setLength(length + 1); //+ (integer value) for spacing
    raf.seek(raf.length());
    raf.writeBytes(Content);
    raf.close();
} 
catch (Exception e) {
    //any exception handling method of ur choice
}

I was almost using the same technology as you did, however I was using my app to connect an Exchange Server via Office 365 platform on WinForms. I too had the same issue as you did, but was able to accomplish by using code which has slight modification of what others have given above.

SmtpClient client = new SmtpClient(exchangeServer, 587);
client.Credentials = new System.Net.NetworkCredential(username, password);
client.EnableSsl = true;
client.Send(msg);

I had to use the Port 587, which is of course the default port over TSL and the did the authentication.

if you are using Eclipse. You should switch to DDMS perspective from top-right corner there after selecting your device you can see folder tree. to install apk manually you can use adb command

adb install apklocation.apk

I think a better way is using the static method fromString to avoid those regular expressions.

    id = UUID.randomUUID();
    UUID uuid = UUID.fromString(id.toString());
    Assert.assertEquals(id.toString(), uuid.toString());

On the other hand

   UUID uuidFalse = UUID.fromString("x");

throws java.lang.IllegalArgumentException: Invalid UUID string: x

You can use ng-change instead of ng-click:

<!doctype html>
<html>
<head>
  <script src="http://code.angularjs.org/1.2.3/angular.min.js"></script>
  <script>
        var app = angular.module('myapp', []);
        app.controller('mainController', function($scope) {
          $scope.vm = {};
          $scope.vm.myClick = function($event) {
                alert($event);
          }
        });     
  </script>  
</head>
<body ng-app="myapp">
  <div ng-controller="mainController">
    <input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">
  </div>
</body>
</html>

For a solution without jQuery check out Visibility.js which provides information about three page states

visible    ... page is visible
hidden     ... page is not visible
prerender  ... page is being prerendered by the browser

and also convenience-wrappers for setInterval

/* Perform action every second if visible */
Visibility.every(1000, function () {
    action();
});

/* Perform action every second if visible, every 60 sec if not visible */
Visibility.every(1000, 60*1000, function () {
    action();
});

A fallback for older browsers (IE < 10; iOS < 7) is also available

oracle driver. `

<dependency>
    <groupId>com.hynnet</groupId>
    <artifactId>jdbc-fo</artifactId>
    <version>12.1.0.2</version>

`

Try this

XElement root = XDocument.Load(fStream).Root;

For an alternative cryptography library, have a look at Bouncy Castle. It has AES and a lot of added functionality. It's a liberal open source library. You will have to use the lightweight, proprietary Bouncy Castle API for this to work though.

Try to update @angular/core using ng update @angular/cli @angular/core

You can hit the key q (for quit) and it should take you to the prompt.

Please see this link.

You could use HorizontalContentAlignment="Stretch" as follows:

<ListBox HorizontalContentAlignment="Stretch"/>

This is yet another reason to use Joda Time

new DateMidnight(2010, 3, 5)

DateMidnight is now deprecated but the same effect can be achieved with Joda Time DateTime

DateTime dt = new DateTime(2010, 3, 5, 0, 0);

My issue was that the encrypt's passPhrase didn't match the decrypt's passPhrase... so it threw this error .. a little misleading.

select group_id, 
       listagg(name, ',') within group (order by name) as names
       over (partition by group_id)   
from demotable
group by group_id 

There are only two ways:

• If the memory pointer to by your char * represents a C string (that is, it contains characters that have a 0-byte to mark its end), you can use strlen(a).

• Otherwise, you need to store the length somewhere. Actually, the pointer only points to one char. But we can treat it as if it points to the first element of an array. Since the "length" of that array isn't known you need to store that information somewhere.

Try this:

StreamWriter file2 = new StreamWriter(@"c:\file.txt", true);
file2.WriteLine(someString);
file2.Close();

My solution:

jQuery('.foo').on('click',function(event){
    if ( !jQuery(event.target).is('.foo *') ) {
        // code goes here
    } 
});

Just for the newcomers: the recent versions of C# allows the use of ? operator to check nulls assignments

parentSplit = xNode.ParentNode.Attributes["split"]?.Value;

I think you are asking two things which are not necessarily the same

I want to extract every 6th element of the original

You can do this by indexing a sequence:

foo <- 1:120
foo[1:20*6]

I would like to create a vector in which each element is the i+6th element of another vector.

An easy way to do this is to supplement a logical factor with FALSEs until i+6:

foo <- 1:120
i <- 1
foo[1:(i+6)==(i+6)]
[1]   7  14  21  28  35  42  49  56  63  70  77  84  91  98 105 112 119

i <- 10
foo[1:(i+6)==(i+6)]
[1]  16  32  48  64  80  96 112

Option: isoformat()

Python's datetime does not support the military timezone suffixes like 'Z' suffix for UTC. The following simple string replacement does the trick:

In [1]: import datetime

In [2]: d = datetime.datetime(2014, 12, 10, 12, 0, 0)

In [3]: str(d).replace('+00:00', 'Z')
Out[3]: '2014-12-10 12:00:00Z'

str(d) is essentially the same as d.isoformat(sep=' ')

See: Datetime, Python Standard Library

Option: strftime()

Or you could use strftime to achieve the same effect:

In [4]: d.strftime('%Y-%m-%dT%H:%M:%SZ')
Out[4]: '2014-12-10 12:00:00Z'

Note: This option works only when you know the date specified is in UTC.

See: datetime.strftime()

Additional: Human Readable Timezone

Going further, you may be interested in displaying human readable timezone information, pytz with strftime %Z timezone flag:

In [5]: import pytz

In [6]: d = datetime.datetime(2014, 12, 10, 12, 0, 0, tzinfo=pytz.utc)

In [7]: d
Out[7]: datetime.datetime(2014, 12, 10, 12, 0, tzinfo=<UTC>)

In [8]: d.strftime('%Y-%m-%d %H:%M:%S %Z')
Out[8]: '2014-12-10 12:00:00 UTC'

Make sure you make it as a separate component I have used tabler-react

import * as React from "react";
import { Page,  Button } from "tabler-react";

            limit: 5, // optional
            page: 1
        };
    }

paginateValue = (page) => {
    this.setState({ page: page });
    console.log(page) // access this value from parent component 
}

paginatePrevValue = (page) => {
    this.setState({ page: page });
    console.log(page)  // access this value from parent component
}
paginateNxtValue = (page) => {
       this.setState({ page: page });
       console.log(page)  // access this value from parent component

                                            ? "primary"
                                            : "secondary"
                                    }
                                >

                            );
                        })}

                        <Button
                            onClick={() => this.paginateNxtValue(this.state.page + 1)}

Literally, just restarted IntelliJ after it kept showing this "install git" message after I have pressed and installed git, and it disappeared, and git works

Actually what made this so confusing is that the Beanstalk people stand behind their very non-standard use of Staging (it comes before development in their diagram, and it's not a mistake!

You can also use the ToLookup LINQ function, which you then can use almost interchangeably with a Dictionary.

_people = personList
    .ToLookup(e => e.FirstandLastName, StringComparer.OrdinalIgnoreCase);
_people.ToDictionary(kl => kl.Key, kl => kl.First()); // Potentially unnecessary

This will essentially do the GroupBy in LukeH's answer, but will give the hashing that a Dictionary provides. So, you probably don't need to convert it to a Dictionary, but just use the LINQ First function whenever you need to access the value for the key.

This function trims a string from left and right. Also it removes carriage returns from the string, an action which is not done by the LTRIM and RTRIM

IF OBJECT_ID(N'dbo.TRIM', N'FN') IS NOT NULL
    DROP FUNCTION dbo.TRIM;
GO
CREATE FUNCTION dbo.TRIM (@STR NVARCHAR(MAX)) RETURNS NVARCHAR(MAX)
BEGIN
    RETURN(LTRIM(RTRIM(REPLACE(REPLACE(@STR ,CHAR(10),''),CHAR(13),''))))
END;
GO

Use val() instead of text()

var hv = $('#h_v').val();
alert(hv);

You had these problems:

• Single quotes was not closed
• You were using text() for an input field
• You were echoing x rather than variable hv

I know question is already answered.

But let me add one point here. This is not only case of true or false. See below:

var val="Do";

Var c= (val == "Do" || val == "Done")
          ? 7
          : 0

Here if val is Do or Done then c will be 7 else it will be zero. In this case c will be 7.

This is actually another perspective of this operator.

There's an excellent plugin called ApplySyntax (previously DetectSyntax) that provides certain other niceties for file-syntax matching. allows regex expressions etc.

GO is not a SQL keyword.

It's a batch separator used by client tools (like SSMS) to break the entire script up into batches

Answered before several times... example 1

This is an interesting question, but I don't think this is actually possible. Whether or not two colors "fit" as background and foreground colors is dependent upon display technology and physiological characteristics of human vision, but most importantly on upon personal tastes shaped by experience. A quick run through MySpace shows pretty clearly that not all human beings perceive colors in the same way. I don't think this is a problem that can be solved algorithmically, although there may be a huge database somewhere of acceptable matching colors.

Try to check at Settings > Advanced. At Valid OAuth redirect URIs, make sure you have a correct domain.

Hope it works.

If you are using Netbeans older version, you have to make changes in maven to use https over http

Open C:\Program Files\NetBeans8.0.2\java\maven\conf\settings.xml and paste below code in between mirrors tag

<mirror>
<id>maven-mirror</id>
<name>Maven Mirror</name>
<url>https://repo.maven.apache.org/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>

It will force maven to use https://repo.maven.apache.org/maven2 url.

You can push a branch to a remote server, say github. You would first have to do the initial project setup, then clone your project and:

git push <remote repo> <your branch>

I've had issues with this. If using a language like php when your page first loads in the iframe grab $_SERVER['HTTP_REFFERER'] and set it to a session variable.

This way when the page loads in the iframe you know the full parent url and query string of the page that loaded it. With cross browser security it's a bit of a headache counting on window.parent anything if you you different domains.

I had been facing this problem for two days and I found that the directory you create in Oracle also needs to created first on your physical disk.

I didn't find this point mentioned anywhere i tried to look up the solution to this.

Example

If you created a directory, let's say, 'DB_DIR'.

CREATE OR REPLACE DIRECTORY DB_DIR AS 'E:\DB_WORKS';

Then you need to ensure that DB_WORKS exists in your E:\ drive and also file system level Read/Write permissions are available to the Oracle process.

My understanding of UTL_FILE from my experiences is given below for this kind of operation.

UTL_FILE is an object under SYS user. GRANT EXECUTE ON SYS.UTL_FILE TO PUBLIC; needs to given while logged in as SYS. Otherwise, it will give declaration error in procedure. Anyone can create a directory as shown:- CREATE OR REPLACE DIRECTORY DB_DIR AS 'E:\DBWORKS'; But CREATE DIRECTORY permission should be in place. This can be granted as shown:- GRANT CREATE ALL DIRECTORY TO user; while logged in as SYS user. However, if this needs to be used by another user, grants need to be given to that user otherwise it will throw error. GRANT READ, WRITE, EXECUTE ON DB_DIR TO user; while loggedin as the user who created the directory. Then, compile your package. Before executing the procedure, ensure that the Directory exists physically on your Disk. Otherwise it will throw 'Invalid File Operation' error. (V. IMPORTANT) Ensure that Filesystem level Read/Write permissions are in place for the Oracle process. This is separate from the DB level permissions granted.(V. IMPORTANT) Execute procedure. File should get populated with the result set of your query.

You can do it using the foreach loop

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

  foreach(DataRow row in dr_art_line_2.Rows)
  {
     QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
  }

Because you're using multiple. Despite it still technically being a dropdown, it doesn't look or act like a standard dropdown. Rather, it populates a list box and lets them select multiple options.

Size determines how many options appear before they have to click down or up to see the other options.

I have a feeling what you want to achieve is only going to be possible with a JavaScript plugin.

Some examples:

jQuery multiselect drop down menu

A simple, but not pure java solution, is to shell out to curl from java, which gives you complete control over how the request is done. If you're just doing this for something simple, this allows you to ignore certificate errors at times, by using this method. This example shows how to make a request against a secure server with a valid or invalid certificate, pass in a cookie, and get the output using curl from java.

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;

public class MyTestClass
{
  public static void main(String[] args) 
  {
    String url = "https://www.google.com";
    String sessionId = "faf419e0-45a5-47b3-96d1-8c62b2a3b558";

    // Curl options are:
    // -k: ignore certificate errors
    // -L: follow redirects
    // -s: non verbose
    // -H: add a http header

    String[] command = { "curl", "-k", "-L", "-s", "-H", "Cookie: MYSESSIONCOOKIENAME=" + sessionId + ";", "-H", "Accept:*/*", url };
    String output = executeShellCmd(command, "/tmp", true, true);
    System.out.println(output);
  }

  public String executeShellCmd(String[] command, String workingFolder, boolean wantsOutput, boolean wantsErrors)
  {
    try
    {
      ProcessBuilder pb = new ProcessBuilder(command);
      File wf = new File(workingFolder);
      pb.directory(wf);

      Process proc = pb.start();
      BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
      BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));

      StringBuffer sb = new StringBuffer();
      String newLine = System.getProperty("line.separator");
      String s;

      // read stdout from the command
      if (wantsOutput)
      {
        while ((s = stdInput.readLine()) != null)
        {
          sb.append(s);
          sb.append(newLine);
        }
      }

      // read any errors from the attempted command
      if (wantsErrors)
      {
        while ((s = stdError.readLine()) != null)
        {
          sb.append(s);
          sb.append(newLine);
        }
      }

      String result = sb.toString();

      return result;
    }
    catch (IOException e)
    {
      throw new RuntimeException("Problem occurred:", e);
    }
  }


}

I solved it this way:

$ brew uninstall --force node
$ brew uninstall --force npm

after it

$ brew install node

which suggested me to overwrite simlinks

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/doc/node/gdbinit
Target /usr/local/share/doc/node/gdbinit
already exists. You may want to remove it:
  rm '/usr/local/share/doc/node/gdbinit'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

after executing

$ brew link --overwrite node

everything worked again.

As of the writing of this, the location option for IOS simulator has been moved to Features -> Location -> Custom Location

Have a look at the documentation for -[UIStoryboard instantiateViewControllerWithIdentifier:]. This allows you to instantiate a view controller from your storyboard using the identifier that you set in the IB Attributes Inspector:

EDITED to add example code:

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard"
                                                         bundle: nil];

MyViewController *controller = (MyViewController*)[mainStoryboard 
                    instantiateViewControllerWithIdentifier: @"<Controller ID>"];

Surprisingly, all other answers only say half the truth or are actually wrong!

• e.stopImmediatePropagation() stops any further handler from being called for this event, no exceptions
• e.stopPropagation() is similar, but does still call all handlers for this phase on this element if not called already

What phase?

E.g. a click event will always first go all the way down the DOM (called “capture phase”), finally reach the origin of the event (“target phase”) and then bubble up again (“bubble phase”). And with addEventListener() you can register multiple handlers for both capture and bubble phase independently. (Target phase calls handlers of both types on the target without distinguishing.)

And this is what the other answers are incorrect about:

• quote: “event.stopPropagation() allows other handlers on the same element to be executed”
  • correction: if stopped in the capture phase, bubble phase handlers will never be reached, also skipping them on the same element
• quote: “event.stopPropagation() [...] is used to stop executions of its corresponding parent handler only”
  • correction: if propagation is stopped in the capture phase, handlers on any children, including the target aren’t called either, not only parents
  • ...and: if propagation is stopped in the bubble phase, all capture phase handlers have already been called, including those on parents

For those with shell access here is a little command to find all files with the BOM set in the public_html directory - be sure to change it to what your correct path on your server is

Code:

grep -rl $'\xEF\xBB\xBF' /home/username/public_html

and if you are comfortable with the vi editor, open the file in vi:

vi /path-to-file-name/file.php

And enter the command to remove the BOM:

set nobomb

Save the file:

wq

Read the data:

foo <- read.table(text="1 349
  1 393
  1 392
  4 459
  3 49
  3 32
  2 94")

And sort:

foo[order(foo$V1),]

This relies on the fact that order keeps ties in their original order. See ?order.

In short \r has ASCII value 13 (CR) and \n has ASCII value 10 (LF). Mac uses CR as line delimiter (at least, it did before, I am not sure for modern macs), *nix uses LF and Windows uses both (CRLF).

Try using urllib2:

This is a very old question, but I found a new solution, so I wrote about it.

First of all, is this way of solution possible while using AutoGenerateColumns?

Yes, that can be done with AttachedProperty as follows.

<DataGrid AutoGenerateColumns="True" 
   local:DataGridOperation.DateTimeFormatAutoGenerate="yy-MM-dd"
   ItemsSource="{Binding}" />

AttachedProperty

There are two AttachedProperty defined that allow you to specify two formats. DateTimeFormatAutoGenerate for DateTime and TimeSpanFormatAutoGenerate for TimeSpan.

class DataGridOperation
{
    public static string GetDateTimeFormatAutoGenerate(DependencyObject obj) => (string)obj.GetValue(DateTimeFormatAutoGenerateProperty);
    public static void SetDateTimeFormatAutoGenerate(DependencyObject obj, string value) => obj.SetValue(DateTimeFormatAutoGenerateProperty, value);
    public static readonly DependencyProperty DateTimeFormatAutoGenerateProperty =
        DependencyProperty.RegisterAttached("DateTimeFormatAutoGenerate", typeof(string), typeof(DataGridOperation),
            new PropertyMetadata(null, (d, e) => AddEventHandlerOnGenerating<DateTime>(d, e)));

    public static string GetTimeSpanFormatAutoGenerate(DependencyObject obj) => (string)obj.GetValue(TimeSpanFormatAutoGenerateProperty);
    public static void SetTimeSpanFormatAutoGenerate(DependencyObject obj, string value) => obj.SetValue(TimeSpanFormatAutoGenerateProperty, value);
    public static readonly DependencyProperty TimeSpanFormatAutoGenerateProperty =
        DependencyProperty.RegisterAttached("TimeSpanFormatAutoGenerate", typeof(string), typeof(DataGridOperation),
            new PropertyMetadata(null, (d, e) => AddEventHandlerOnGenerating<TimeSpan>(d, e)));

    private static void AddEventHandlerOnGenerating<T>(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (!(d is DataGrid dGrid))
            return;

        if ((e.NewValue is string format))
            dGrid.AutoGeneratingColumn += (o, e) => AddFormat_OnGenerating<T>(e, format);
    }

    private static void AddFormat_OnGenerating<T>(DataGridAutoGeneratingColumnEventArgs e, string format)
    {
        if (e.PropertyType == typeof(T))
            (e.Column as DataGridTextColumn).Binding.StringFormat = format;
    }
}

You are deleting the row from the gridview but you are then going and calling databind again which is just refreshing the gridview to the same state that the original datasource is in.

Either remove it from the datasource and then databind, or databind and remove it from the gridview without redatabinding.

If you were to use the C library then this could be done:

time_t t;
struct tm * timeinfo;

time (&t);
timeinfo = localtime (&t);

NSLog(@"Hour: %d Minutes: %d", timeinfo->tm_hour, timeinfo->tm_min);

And using Swift:

var t = time_t()
time(&t)
let x = localtime(&t)

println("Hour: \(x.memory.tm_hour) Minutes: \(x.memory.tm_min)")

For further guidance see: http://www.cplusplus.com/reference/ctime/localtime/

You want to do something like this instead:

<Button>
    <StackPanel>
        <Image Source="Pictures/apple.jpg" />
        <TextBlock>Disconnect from Server</TextBlock>
    </StackPanel>
</Button>

I would just raise ValueError, unless you need a more specific exception..

def import_to_orm(name, save=False, recurse=False):
    if recurse and not save:
        raise ValueError("save must be True if recurse is True")

There's really no point in doing class BadValueError(ValueError):pass - your custom class is identical in use to ValueError, so why not use that?

The pthread_exit() API

as has been already remarked, is used for the calling thread termination. After a call to that function a complicating clean up mechanism is started. When it completes the thread is terminated. The pthread_exit() API is also called implicitly when a call to the return() routine occurs in a thread created by pthread_create(). Actually, a call to return() and a call to pthread_exit() have the same impact, being called from a thread created by pthread_create().

It is very important to distinguish the initial thread, implicitly created when the main() function starts, and threads created by pthread_create(). A call to the return() routine from the main() function implicitly invokes the exit() system call and the entire process terminates. No thread clean up mechanism is started. A call to the pthread_exit() from the main() function causes the clean up mechanism to start and when it finishes its work the initial thread terminates.

What happens to the entire process (and to other threads) when pthread_exit() is called from the main() function depends on the PTHREAD implementation. For example, on IBM OS/400 implementation the entire process is terminated, including other threads, when pthread_exit() is called from the main() function. Other systems may behave differently. On most modern Linux machines a call to pthread_exit() from the initial thread does not terminate the entire process until all threads termination. Be careful using pthread_exit() from main(), if you want to write a portable application.

The pthread_join() API

is a convenient way to wait for a thread termination. You may write your own function that waits for a thread termination, perhaps more suitable to your application, instead of using pthread_join(). For example, it can be a function based on waiting on conditional variables.

I would recommend for reading a book of David R. Butenhof “Programming with POSIX Threads”. It explains the discussed topics (and more complicated things) very well (although some implementation details, such as pthread_exit usage in the main function, not always reflected in the book).

The basic difference, is that provider allows to set primitive (non-objects), array, or callback function values into the factory declared variable, and thus if returning an object it has to be explicitly declared and returned.

On the other hand a service can only be used to set the service declared variable to an object, thus we can avoid the explicit creation and returning of the objects, while on the other hand it allows usage of the this keyword.

Or in short words "provider is a more generic form while service is limited to objects only".

Use JContainer.Parse(str) method to check if the str is a valid Json. If this throws exception then it is not a valid Json.

JObject.Parse - Can be used to check if the string is a valid Json object
JArray.Parse - Can be used to check if the string is a valid Json Array
JContainer.Parse - Can be used to check for both Json object & Array

You can Try using :- git ls-files -s

You have to be careful with what you want to do, because it is not just about to get the time.

The batch has internal variables to represent the date and the tme: %DATE% %TIME%. But they dependent on the Windows Locale.

%Date%:

• dd.MM.yyyy
• dd.MM.yy
• d.M.yy
• dd/MM/yy
• yyyy-MM-dd

%TIME%:

• H:mm:ss,msec
• HH:mm:ss,msec

Now, how long your script will work and when? For example, if it will be longer than a day and does pass the midnight it will definitely goes wrong, because difference between 2 timestamps between a midnight is a negative value! You need the date to find out correct distance between days, but how you do that if the date format is not a constant? Things with %DATE% and %TIME% might goes worser and worser if you continue to use them for the math purposes.

The reason is the %DATE% and %TIME% are exist is only to show a date and a time to user in the output, not to use them for calculations. So if you want to make correct distance between some time values or generate some unique value dependent on date and time then you have to use something different and accurate than %DATE% and %TIME%.

I am using the wmic windows builtin utility to request such things (put it in a script file):

for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE`) do if "%%i" == "LocalDateTime" echo.%%j

or type it in the cmd.exe console:

for /F "usebackq tokens=1,2 delims==" %i in (`wmic os get LocalDateTime /VALUE`) do @if "%i" == "LocalDateTime" echo.%j

The disadvantage of this is a slow performance in case of frequent calls. On mine machine it is about 12 calls per second.

If you want to continue use this then you can write something like this (get_datetime.bat):

@echo off

rem Description:
rem   Independent to Windows locale date/time request.

rem Drop last error level
cd .

rem drop return value
set "RETURN_VALUE="

for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if "%%i" == "LocalDateTime" set "RETURN_VALUE=%%j"

if not "%RETURN_VALUE%" == "" (
  set "RETURN_VALUE=%RETURN_VALUE:~0,18%"
  exit /b 0
)

exit /b 1

Now, you can parse %RETURN_VALUE% somethere in your script:

call get_datetime.bat
set "FILE_SUFFIX=%RETURN_VALUE:.=_%"
set "FILE_SUFFIX=%FILE_SUFFIX:~8,2%_%FILE_SUFFIX:~10,2%_%FILE_SUFFIX:~12,6%"
echo.%FILE_SUFFIX%

Common reasons for the error:

• use of assignment (=) instead of equality (==/===)
• assigning to result of function foo() = 42 instead of passing arguments (foo(42))
• simply missing member names (i.e. assuming some default selection) : getFoo() = 42 instead of getFoo().theAnswer = 42 or array indexing getArray() = 42 instead of getArray()[0]= 42

In this particular case you want to use == (or better === - What exactly is Type Coercion in Javascript?) to check for equality (like if(one === "rock" && two === "rock"), but it the actual reason you are getting the error is trickier.

The reason for the error is Operator precedence. In particular we are looking for && (precedence 6) and = (precedence 3).

Let's put braces in the expression according to priority - && is higher than = so it is executed first similar how one would do 3+4*5+6 as 3+(4*5)+6:

 if(one= ("rock" && two) = "rock"){...

Now we have expression similar to multiple assignments like a = b = 42 which due to right-to-left associativity executed as a = (b = 42). So adding more braces:

 if(one= (  ("rock" && two) = "rock" )  ){...

Finally we arrived to actual problem: ("rock" && two) can't be evaluated to l-value that can be assigned to (in this particular case it will be value of two as truthy).

Note that if you'd use braces to match perceived priority surrounding each "equality" with braces you get no errors. Obviously that also producing different result than you'd expect - changes value of both variables and than do && on two strings "rock" && "rock" resulting in "rock" (which in turn is truthy) all the time due to behavior of logial &&:

if((one = "rock") && (two = "rock"))
{
   // always executed, both one and two are set to "rock"
   ...
}

For even more details on the error and other cases when it can happen - see specification:

Assignment

LeftHandSideExpression = AssignmentExpression
...
Throw a SyntaxError exception if the following conditions are all true:
...
IsStrictReference(lref) is true

Left-Hand-Side Expressions

and The Reference Specification Type explaining IsStrictReference:

... function calls are permitted to return references. This possibility is admitted purely for the sake of host objects. No built-in ECMAScript function defined by this specification returns a reference and there is no provision for a user-defined function to return a reference...

Why not so?:

set host=%COMPUTERNAME%
echo %host%

I am not allowed to comment to pkyeck's response which did not work for a few people including me, so I am adding a separate comment in continuation to his response:

Basically try to add the variable which he has mentioned in the .profile file if the .bash_profile did not work. It is located in your home directory and then restart the terminal. that got it working for me.

The obvious blocker would be that you do not have an access to edit the .profile file, for which use the "touch" to check the access and the "sudo" command to get the access

1. touch .profile

2. vi .profile

Here are the variable pkyeck suggests that we added as a solution which worked with editing .profile for me:

1. export M2_HOME=/apache-maven-3.3.3

2. export PATH=$PATH:$M2_HOME/bin

With this, you can perform some code in the get or set scope.

private string _myProperty;
public string myProperty
{
    get { return _myProperty; }
    set { _myProperty = value; }
}

You also can use automatic properties:

public string myProperty
{
    get;
    set;
}

And .Net Framework will manage for you. It was create because it is a good pratice and make it easy to do.

You also can control the visibility of these scopes, for sample:

public string myProperty
{
    get;
    private set;
}

public string myProperty2
{
    get;
    protected set;
}

public string myProperty3
{
    get; 
}

Update

Now in C# you can initialize the value of a property. For sample:

public int Property { get; set; } = 1;

If also can define it and make it readonly, without a set.

public int Property { get; } = 1;

And finally, you can define an arrow function.

public int Property => GetValue();

You have installed the library in a non-standard location ($HOME/zlib/). That means the compiler will not know where your header files are and you need to tell the compiler that.

You can add a path to the list that the compiler uses to search for header files by using the -I (upper-case i) option.

Also note that the LD_LIBRARY_PATH is for the run-time linker and loader, and is searched for dynamic libraries when attempting to run an application. To add a path for the build-time linker use the -L option.

All-together the command line should look like

$ c++ -I$HOME/zlib/include some_file.cpp -L$HOME/zlib/lib -lz

I'd recommend NPOI. NPOI is FREE and works exclusively with .XLS files. It has helped me a lot.

Detail: you don't need to have Microsoft Office installed on your machine to work with .XLS files if you use NPOI.

import { Directive,Input,Outpu,ElementRef,Renderer} from '@angular/core';

@Directive({
  selector:"[move]",
  host:{
    '(click)':"show()"
  }
})

export class GetEleDirective{

  constructor(private el:ElementRef){

  }
  show(){
    console.log(this.el.nativeElement);

    console.log('height---' + this.el.nativeElement.offsetHeight);  //<<<===here
    console.log('width---' + this.el.nativeElement.offsetWidth);    //<<<===here
  }
}

Same way you can use it within component itself wherever you need it.

Try this code.

Update for RxJS 6 (April 2018)

It is now perfectly fine to import directly from rxjs. (As can be seen in Angular 6+). Importing from rxjs/operators is also fine and it is actually no longer possible to import operators globally (one of major reasons for refactoring rxjs 6 and the new approach using pipe). Thanks to this treeshaking can now be used as well.

Sample code from rxjs repo:

import { Observable, Subject, ReplaySubject, from, of, range } from 'rxjs';
import { map, filter, switchMap } from 'rxjs/operators';

range(1, 200)
  .pipe(filter(x => x % 2 === 1), map(x => x + x))
  .subscribe(x => console.log(x));

Backwards compatibility for rxjs < 6?

rxjs team released a compatibility package on npm that is pretty much install & play. With this all your rxjs 5.x code should run without any issues. This is especially useful now when most of the dependencies (i.e. modules for Angular) are not yet updated.

This is old but it is still useful, Fully tested with QT5.3.

Be carreful, example concerning the ressources path :

In my case I created a ressources directory named "Ressources" in the source directory project.

The folder "ressources" contain pictures and icons.Then I added a prefix "Images" in Qt So the pixmap path become:

QPixmap pixmap(":/images/Ressources/icone_pdf.png");

1. you need to create and id for the buttons you need to refference: btn1.setId(1);
2. you can use the params variable to add parameters to your layout, i think the method is addRule(), check out the android java docs for this LayoutParams object.

spring.jackson.serialization-inclusion=non_null used to work for us

But when we upgraded spring boot version to 1.4.2.RELEASE or higher, it stopped working.

Now, another property spring.jackson.default-property-inclusion=non_null is doing the magic.

in fact, serialization-inclusion is deprecated. This is what my intellij throws at me.

Deprecated: ObjectMapper.setSerializationInclusion was deprecated in Jackson 2.7

So, start using spring.jackson.default-property-inclusion=non_null instead

Let's say your table has two other columns: foo and bar

INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, "155"
  FROM Table
 WHERE Event_ID = "120"

Set AUTO_INCREMENT to PRIMARY KEY

SELECT pg_size_pretty(pg_database_size('name of database'));

Will give you the total size of a particular database however I don't think you can do all databases within a server.

However you could do this...

DO
$$
DECLARE
r   RECORD;
db_size TEXT;
BEGIN
FOR r in
SELECT datname FROM pg_database
WHERE datistemplate = false
LOOP
db_size:= (SELECT pg_size_pretty(pg_database_size(r.datname)));

RAISE NOTICE 'Database:% , Size:%', r.datname , db_size;

END LOOP;
END;
$$

I'm using OSX 10.11.6 and this article works for me.

The line in the theme style works fine, yet that replaces the animation with a white screen. Especially on a slower phone - it is really annoying. So, if you want an instant transition - you could use this in the theme style:

<item name="android:windowAnimationStyle">@null</item>
<item name="android:windowDisablePreview">true</item>

Do you want to disable error reporting, or just prevent the user from seeing it? It’s usually a good idea to log errors, even on a production site.

# in your PHP code:
ini_set('display_errors', '0');     # don't show any errors...
error_reporting(E_ALL | E_STRICT);  # ...but do log them

They will be logged to your standard system log, or use the error_log directive to specify exactly where you want errors to go.

The % operator is for integers. You're looking for the fmod() function.

#include <cmath>

int main()
{
    double x = 6.3;
    double y = 2.0;
    double z = std::fmod(x,y);

}

fastest way is by signing with the debug keystore:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/.android/debug.keystore app.apk androiddebugkey -storepass android

or on Windows:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore %USERPROFILE%/.android/debug.keystore test.apk androiddebugkey -storepass android

If you simply call interrupt(), the thread will not automatically be closed. Instead, the Thread might even continue living, if isInterrupted() is implemented accordingly. The only way to guaranteedly close a thread, as asked for by OP, is

Thread.currentThread().stop();

Method is deprecated, however.

Calling return only returns from the current method. This only terminates the thread if you're at its top level.

Nevertheless, you should work with interrupt() and build your code around it.

Your code looks good, in fact it works (apart from the calls themselves) when copied & pasted into a sample jsFiddle: http://jsfiddle.net/VGaWD/

Hard to say what is going on without seeing a more complete example but I hope that the above jsFiddle will be helpful. What I'm suspecting is that you are not initializing your app with the 'productServices' module. It would give the same error, we can see this in another jsFiddle: http://jsfiddle.net/a69nX/1/

If you are planning to work with AngularJS and MongoLab I would suggest using an existing adapter for the $resource and MongoLab: https://github.com/pkozlowski-opensource/angularjs-mongolab It eases much of the pain working with MongoLab, you can see it in action here: http://jsfiddle.net/pkozlowski_opensource/DP4Rh/ Disclaimer! I'm maintaining this adapter (written based on AngularJS examples) so I'm obviously biased here.

In case this helps someone, for me, none of the above was sufficient. I still couldn't build, VS still couldn't find the references. The key was simply to close and reopen the solution after restoring the packages.

Here's the scenario (using Visual Studio 2012):

You open a Solution that has missing packages. The references show that VS can't find them. There are many ways to restore the missing packages, including

• building a solution that is set to auto-restore
• opening the Package Manager Console and clicking the nice "Restore" button
• doing nuget restore if you have the command line nuget installed

But no matter what the approach, those references will still be shown as missing. And when you build it will fail. Sigh. However if you close the solution and re-open it, now VS checks those nice <HintPath>s again, finds that the packages are back where they belong, and all is well with the world.

Update

Is Visual Studio still not seeing that you have the package? Still showing a reference that it can't resolve? Make sure that the version of package you restored is exactly the same as the <HintPath> in your .csproj file. Even a minor bug fix number (e.g. 1.10.1 to 1.10.2) will cause the reference to fail. You can fix this either by directly editing your csproj xml, or else by removing the reference and making a new one pointing at the newly-restored version in the packages directory.

>>> x = 'foo'
>>> x
'foo'

So the name x is attached to 'foo' string. When you call for example repr(x) the interpreter puts 'foo' instead of x and then calls repr('foo').

>>> repr(x)
"'foo'"
>>> x.__repr__()
"'foo'"

repr actually calls a magic method __repr__ of x, which gives the string containing the representation of the value 'foo' assigned to x. So it returns 'foo' inside the string "" resulting in "'foo'". The idea of repr is to give a string which contains a series of symbols which we can type in the interpreter and get the same value which was sent as an argument to repr.

>>> eval("'foo'")
'foo'

When we call eval("'foo'"), it's the same as we type 'foo' in the interpreter. It's as we directly type the contents of the outer string "" in the interpreter.

>>> eval('foo')

Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    eval('foo')
  File "<string>", line 1, in <module>
NameError: name 'foo' is not defined

If we call eval('foo'), it's the same as we type foo in the interpreter. But there is no foo variable available and an exception is raised.

>>> str(x)
'foo'
>>> x.__str__()
'foo'
>>> 

str is just the string representation of the object (remember, x variable refers to 'foo'), so this function returns string.

>>> str(5)
'5'

String representation of integer 5 is '5'.

>>> str('foo')
'foo'

And string representation of string 'foo' is the same string 'foo'.

Your function worked for me after changing its declaration to this ...

Function processArr(Arr As Variant) As String

You could also consider a ParamArray like this ...

Function processArr(ParamArray Arr() As Variant) As String
    'Dim N As Variant
    Dim N As Long
    Dim finalStr As String
    For N = LBound(Arr) To UBound(Arr)
        finalStr = finalStr & Arr(N)
    Next N
    processArr = finalStr
End Function

And then call the function like this ...

processArr("foo", "bar")

I was having the same problem, and solved it by replacing Manifest.permission.READ_PHONE_STATE with android.Manifest.permission.READ_PHONE_STATE.

Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).

Instead, I used this method:

1. Close all but one instance of Visual Studio.
2. In the running instance, access the menu Tools->Extensions and Updates.
3. In that dialog, choose Online->Visual Studio Marketplace->Tools->Setup & Deployment.
4. From the list that appears, select Microsoft Visual Studio 2017 Installer Projects.

Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application..... with filename = GetFileName(Range("A1"))

Function GetFileName(rngNamedCell As Range) As String
    Dim strSaveDirectory As String: strSaveDirectory = ""
    Dim strFileName As String: strFileName = ""
    Dim strTestPath As String: strTestPath = ""
    Dim strFileBaseName As String: strFileBaseName = ""
    Dim strFilePath As String: strFilePath = ""
    Dim intFileCounterIndex As Integer: intFileCounterIndex = 1

    ' Get the users desktop directory.
    strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
    Debug.Print "Saving to: " & strSaveDirectory

    ' Base file name
    strFileBaseName = Trim(rngNamedCell.Value)
    Debug.Print "File Name will contain: " & strFileBaseName

    ' Loop until we find a free file number
    Do
        If intFileCounterIndex > 1 Then
            ' Build test path base on current counter exists.
            strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
        Else
            ' Build test path base just on base name to see if it exists.
            strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
        End If

        If (Dir(strTestPath) = "") Then
            ' This file path does not currently exist. Use that.
            strFileName = strTestPath
        Else
            ' Increase the counter as we have not found a free file yet.
            intFileCounterIndex = intFileCounterIndex + 1
        End If

    Loop Until strFileName <> ""

    ' Found useable filename
    Debug.Print "Free file name: " & strFileName
    GetFileName = strFileName

End Function

The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.

In Action

My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Sub Testing()
    Dim filename As String: filename = GetFileName(Range("o1"))

    ActiveWorkbook.Worksheets("Sheet1").Range("A1:N24").ExportAsFixedFormat Type:=xlTypePDF, _
                                              filename:=filename, _
                                              Quality:=xlQualityStandard, _
                                              IncludeDocProperties:=True, _
                                              IgnorePrintAreas:=False, _
                                              OpenAfterPublish:=False
End Sub

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.

You can use dangerouslySetInnerHTML, e.g.

render: function() {
    return (
        <div className="content" dangerouslySetInnerHTML={{__html: thisIsMyCopy}}></div>
    );
}

Although the following is not way to do it in GUI but you can get autoincrementing simply using the IDENTITY datatype(start, increment):

CREATE TABLE "dbo"."TableName"
(
   id int IDENTITY(1,1) PRIMARY KEY NOT NULL,
   name varchar(20),
);

the insert statement should list all columns except the id column (it will be filled with autoincremented value):

INSERT INTO "dbo"."TableName" (name) VALUES ('alpha');
INSERT INTO "dbo"."TableName" (name) VALUES ('beta');

and the result of

SELECT id, name FROM "dbo"."TableName";

will be

id    name
--------------------------
1     alpha
2     beta

Pure JavaScript ES6 solution

• Catch every option with a querySelectorAll function and split the values string.
• Use Array#forEach to iterate over every element from the values array.
• Use Array#find to find the option matching given value.
• Set it's selected attribute to true.

Note: Array#from transforms an array-like object into an array and then you are able to use Array.prototype functions on it, like find or map.

var values = "Test,Prof,Off",_x000D_
    options = Array.from(document.querySelectorAll('#strings option'));_x000D_
_x000D_
values.split(',').forEach(function(v) {_x000D_
  options.find(c => c.value == v).selected = true;_x000D_
});

<select name='strings' id="strings" multiple style="width:100px;">_x000D_
    <option value="Test">Test</option>_x000D_
    <option value="Prof">Prof</option>_x000D_
    <option value="Live">Live</option>_x000D_
    <option value="Off">Off</option>_x000D_
    <option value="On">On</option>_x000D_
</select>

SELECT * 
FROM emp_salaryrevise_view 
WHERE curr_year Between '2008' AND '2009' 
    AND MNTH Between '12' AND '1'

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

A similar problem happened to me, I simply mixed the order of the callback params. Make sure your are setting up the callback functions in the correct order. At least for anyone having the same problem.

router.post('/', function(req, res){});

I'm not sure what you are doing wrong here, when I build a form using form classes Symfony takes care of selecting the correct option in the list. Here's an example of one of my forms that works.

In the controller for the edit action:

$entity = $em->getRepository('FooBarBundle:CampaignEntity')->find($id);

if (!$entity) {
throw $this->createNotFoundException('Unable to find CampaignEntity entity.');
}


$editForm = $this->createForm(new CampaignEntityType(), $entity);
$deleteForm = $this->createDeleteForm($id);

return $this->render('FooBarBundle:CampaignEntity:edit.html.twig', array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));

The campaign entity type class (src: Foo\BarBundle\Form\CampaignEntityType.php):

namespace Foo\BarBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Doctrine\ORM\EntityRepository;

class CampaignEntityType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder
        ->add('store', 'entity', array('class'=>'FooBarBundle:Store', 'property'=>'name', 'em'=>'my_non_default_em','required'  => true, 'query_builder' => function(EntityRepository $er) {return $er->createQueryBuilder('s')->orderBy('s.name', 'ASC');}))
        ->add('reward');
    }
    public function getName()
    {
        return 'foo_barbundle_campaignentitytype';
    }
}

Bootstrap 4

Now that BS4 is flexbox, the fixed-fluid is simple. Just set the width of the fixed column, and use the .col class on the fluid column.

.sidebar {
    width: 180px;
    min-height: 100vh;
}

<div class="row">
    <div class="sidebar p-2">Fixed width</div>
    <div class="col bg-dark text-white pt-2">
        Content
    </div>
</div>

Bootstrap 3..

One approach to a fixed-fluid layout is using media queries that align with Bootstrap's breakpoints so that you only use the fixed width columns are larger screens and then let the layout stack responsively on smaller screens...

@media (min-width:768px) {
  #sidebar {
      min-width: 300px;
      max-width: 300px;
  }
  #main {
      width:calc(100% - 300px);
  }
}

UPDATE: this was solved by rebooting but there was another error when running app. This time tomcat woudnt start. To solve this (bugs with latest apache and netbeans versions) follow: Error starting Tomcat from NetBeans - '127.0.0.1*' is not recognized as an internal or external command

Say the other guy created bar on top of foo, but you created baz in the meantime and then merged, giving a history of

$ git lola
*   2582152 (HEAD, master) Merge branch 'otherguy'
|\  
| * c7256de (otherguy) bar
* | b7e7176 baz
|/  
* 9968f79 foo

Note: git lola is a non-standard but useful alias.

No dice with git revert:

$ git revert HEAD
fatal: Commit 2582152... is a merge but no -m option was given.

Charles Bailey gave an excellent answer as usual. Using git revert as in

$ git revert --no-edit -m 1 HEAD
[master e900aad] Revert "Merge branch 'otherguy'"
 0 files changed, 0 insertions(+), 0 deletions(-)
 delete mode 100644 bar

effectively deletes bar and produces a history of

$ git lola
* e900aad (HEAD, master) Revert "Merge branch 'otherguy'"
*   2582152 Merge branch 'otherguy'
|\  
| * c7256de (otherguy) bar
* | b7e7176 baz
|/  
* 9968f79 foo

But I suspect you want to throw away the merge commit:

$ git reset --hard HEAD^
HEAD is now at b7e7176 baz

$ git lola
* b7e7176 (HEAD, master) baz
| * c7256de (otherguy) bar
|/  
* 9968f79 foo

As documented in the git rev-parse manual

<rev>^, e.g. HEAD^, v1.5.1^0
A suffix ^ to a revision parameter means the first parent of that commit object. ^<n> means the n-th parent (i.e. <rev>^ is equivalent to <rev>^1). As a special rule, <rev>^0 means the commit itself and is used when <rev> is the object name of a tag object that refers to a commit object.

so before invoking git reset, HEAD^ (or HEAD^1) was b7e7176 and HEAD^2 was c7256de, i.e., respectively the first and second parents of the merge commit.

Be careful with git reset --hard because it can destroy work.

The below codepen identifies IE version in all cases (IE<=9, IE10, IE11 and IE/Edge)

function detectIE() {
    var ua = window.navigator.userAgent;
    var msie = ua.indexOf('MSIE ');
    if (msie > 0) {
        // IE 10 or older => return version number
        return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
    }
    var trident = ua.indexOf('Trident/');
    if (trident > 0) {
        // IE 11 => return version number
        var rv = ua.indexOf('rv:');
        return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
    }
    var edge = ua.indexOf('Edge/');
    if (edge > 0) {
        // Edge (IE 12+) => return version number
        return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
    }
    // other browser
    return false;
}

With this code i solved my problem.For back button paste these two line code.Hope this will help you.

Only paste this code on button click

super.onBackPressed();

Example:-

Button backButton = (Button)this.findViewById(R.id.back);
backButton.setOnClickListener(new OnClickListener() {
  @Override
  public void onClick(View v) {
    super.onBackPressed();
  }
});

Centering is one of the biggest issues in CSS. However, some tricks exist:

To center your table horizontally, you can set left and right margin to auto:

<style>
  #test {
    width:100%;
    height:100%;
  }
  table {
    margin: 0 auto; /* or margin: 0 auto 0 auto */
  }
</style>

To center it vertically, the only way is to use javascript:

var tableMarginTop = Math.round( (testHeight - tableHeight) / 2 );
$('table').css('margin-top', tableMarginTop) # with jQuery
$$('table')[0].setStyle('margin-top', tableMarginTop) # with Mootools

No vertical-align:middle is possible as a table is a block and not an inline element.

Edit

Here is a website that sums up CSS centering solutions: http://howtocenterincss.com/

Wrapping the existing formula in IFERROR will not achieve:

the average of cells that contain non-zero, non-blank values.

I suggest trying:

=if(ArrayFormula(isnumber(K23:M23)),AVERAGEIF(K23:M23,"<>0"),"")

This is specifically a special case because computers represent numbers in base 2. This is generalizable:

(number)_base % base^x

is equivilent to the last x digits of (number)_base.

First we grab the command output, then wrap it and select one of its properties. There is only one and its "Name" which is what we want. So we select the groups property with ".name" then output it.

to text file

 (Get-ADGroupMember 'Domain Admins' |Select name).name | out-file Admins1.txt

to csv

(Get-ADGroupMember 'Domain Admins' |Select name).name | export-csv -notypeinformation "Admins1.csv"

this is my solution:

    public Bitmap Blend(Bitmap topImage1, Bitmap bottomImage1, PorterDuff.Mode Type) {

        Bitmap workingBitmap = Bitmap.createBitmap(topImage1);
        Bitmap topImage = workingBitmap.copy(Bitmap.Config.ARGB_8888, true);

        Bitmap workingBitmap2 = Bitmap.createBitmap(bottomImage1);
        Bitmap bottomImage = workingBitmap2.copy(Bitmap.Config.ARGB_8888, true);

        Rect dest = new Rect(0, 0, bottomImage.getWidth(), bottomImage.getHeight());
        new BitmapFactory.Options().inPreferredConfig = Bitmap.Config.ARGB_8888;
        bottomImage.setHasAlpha(true);
        Canvas canvas = new Canvas(bottomImage);
        Paint paint = new Paint();

        paint.setXfermode(new PorterDuffXfermode(Type));

        paint.setFilterBitmap(true);
        canvas.drawBitmap(topImage, null, dest, paint);
        return bottomImage;
    }

usage :

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.SCREEN));

or

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.OVERLAY));

and the results :

Overlay mode :

Screen mode:

You can use .filter() method of the Array object:

var filtered = workItems.filter(function(element) {
   // Create an array using `.split()` method
   var cats = element.category.split(' ');

   // Filter the returned array based on specified filters
   // If the length of the returned filtered array is equal to
   // length of the filters array the element should be returned  
   return cats.filter(function(cat) {
       return filtersArray.indexOf(cat) > -1;
   }).length === filtersArray.length;
});

http://jsfiddle.net/6RBnB/

Some old browsers like IE8 doesn't support .filter() method of the Array object, if you are using jQuery you can use .filter() method of jQuery object.

jQuery version:

var filtered = $(workItems).filter(function(i, element) {
   var cats = element.category.split(' ');

    return $(cats).filter(function(_, cat) {
       return $.inArray(cat, filtersArray) > -1;
    }).length === filtersArray.length;
});

You get all tables containing the column product using this statment:

SELECT DISTINCT TABLE_NAME 
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE COLUMN_NAME IN ('Product')
        AND TABLE_SCHEMA='YourDatabase';

Then you have to run a cursor on these tables so you select eachtime:

Select * from OneTable where product like '%XYZ%'

The results should be entered into a 3rd table or view, take a look here.

Notice: This can work only if the structure of all table is similar, otherwise aou will have to see which columns are united for all these tables and create your result table / View to contain only these columns.

Often, for init default values of form i use fixtures. Of cause this way is not easiest, but very comfortable.

Example:

class LoadSurgeonPlanData implements FixtureInterface
{
    public function load(ObjectManager $manager)
    {
        $surgeonPlan = new SurgeonPlan();

        $surgeonPlan->setName('Free trial');
        $surgeonPlan->setPrice(0);
        $surgeonPlan->setDelayWorkHours(0);
        $surgeonPlan->setSlug('free');

        $manager->persist($surgeonPlan);
        $manager->flush();        
    }   
}

Yet, symfony type field have the option data.

Example

$builder->add('token', 'hidden', array(
    'data' => 'abcdef',
));

IT returns number of objects are updated in table.

update_counts = ModelClass.objects.filter(name='bar').update(name="foo")

The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.

To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.

Could I write "table" or any other html tag instead of "/" ?

Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.

Here a few links:

• XSL templates
• XPath
• A good book about XML - Beginning XML

Instead of using a loop to find the authority from UserDetails you can do:

Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();
boolean authorized = authorities.contains(new SimpleGrantedAuthority("ROLE_ADMIN"));
