How about:

String.prototype.strcmp = function(s) {
    if (this < s) return -1;
    if (this > s) return 1;
    return 0;
}

Then, to compare s1 with 2:

s1.strcmp(s2)

using the Reflections library, it's easy as:

Reflections reflections = new Reflections("my.pkg", new SubTypesScanner(false));

That would scan all classes in the url/s that contains my.pkg package.

• the false parameter means - don't exclude the Object class, which is excluded by default.
• in some scenarios (different containers) you might pass the classLoader as well as a parameter.

So, getting all classes is effectively getting all subtypes of Object, transitively:

Set<String> allClasses = 
    reflections.getStore().getSubTypesOf(Object.class.getName());

(The ordinary way reflections.getSubTypesOf(Object.class) would cause loading all classes into PermGen and would probably throw OutOfMemoryError. you don't want to do it...)

If you want to get all direct subtypes of Object (or any other type), without getting its transitive subtypes all in once, use this:

Collection<String> directSubtypes = 
    reflections.getStore().get(SubTypesScanner.class).get(Object.class.getName());

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

If you want to use echo "a\tb" in a script, you run the script as:

# sh -e myscript.sh

Alternatively, you can give to myscript.sh the execution permission, and then run the script.

# chmod +x myscript.sh
# ./myscript.sh

You can use functools.partial for this (as you suspected):

from functools import partial

def target(lock, iterable_item):
    for item in iterable_item:
        # Do cool stuff
        if (... some condition here ...):
            lock.acquire()
            # Write to stdout or logfile, etc.
            lock.release()

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    l = multiprocessing.Lock()
    func = partial(target, l)
    pool.map(func, iterable)
    pool.close()
    pool.join()

Example:

def f(a, b, c):
    print("{} {} {}".format(a, b, c))

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    a = "hi"
    b = "there"
    func = partial(f, a, b)
    pool.map(func, iterable)
    pool.close()
    pool.join()

if __name__ == "__main__":
    main()

Output:

hi there 1
hi there 2
hi there 3
hi there 4
hi there 5

What is the type of c.PhysicalAddresses? If it's Dictionary<TKey,TValue>, then you can use the ContainsKey method.

Here's my take on this in case anyone comes across this thread:

This helps protect against non-numerical data destroying either of your final variables that determine lat and lng.

It works by taking in all of your coordinates, parsing them into separate lat and lng elements of an array, then determining the average of each. That average should be the center (and has proven true in my test cases.)

var coords = "50.0160001,3.2840073|50.014458,3.2778274|50.0169713,3.2750587|50.0180745,3.276742|50.0204038,3.2733474|50.0217796,3.2781737|50.0293064,3.2712542|50.0319918,3.2580816|50.0243287,3.2582281|50.0281447,3.2451177|50.0307925,3.2443178|50.0278165,3.2343882|50.0326574,3.2289809|50.0288569,3.2237612|50.0260081,3.2230589|50.0269495,3.2210104|50.0212645,3.2133541|50.0165868,3.1977592|50.0150515,3.1977341|50.0147901,3.1965286|50.0171915,3.1961636|50.0130074,3.1845098|50.0113267,3.1729483|50.0177206,3.1705726|50.0210692,3.1670394|50.0182166,3.158297|50.0207314,3.150927|50.0179787,3.1485753|50.0184944,3.1470782|50.0273077,3.149845|50.024227,3.1340514|50.0244172,3.1236235|50.0270676,3.1244474|50.0260853,3.1184879|50.0344525,3.113806";

      var centerCoords = filteredtextCoordinatesArray[i]; 
      var centerCoordsArray = centerCoords.split(',');

      if (isNaN(Number(centerCoordsArray[0]))) {

Use sprintf (or snprintf if like me you can't count) with format string "pre_%d_suff".

For what it's worth, with itoa/strcat you could do:

char dst[12] = "pre_";
itoa(i, dst+4, 10);
strcat(dst, "_suff");

I saw that someone was wondering how to do it for another controller.

In my case I had all of my email templates in the Views/Email folder, but you could modify this to pass in the controller in which you have views associated for.

public static string RenderViewToString(Controller controller, string viewName, object model)
    {
        var oldController = controller.RouteData.Values["controller"].ToString();

        if (controller.GetType() != typeof(EmailController))
            controller.RouteData.Values["controller"] = "Email";

        var oldModel = controller.ViewData.Model;
        controller.ViewData.Model = model;
        try
        {
            using (var sw = new StringWriter())
            {
                var viewResult = ViewEngines.Engines.FindView(controller.ControllerContext, viewName,
                                                                           null);

                var viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
                viewResult.View.Render(viewContext, sw);

                //Cleanup
                controller.ViewData.Model = oldModel;
                controller.RouteData.Values["controller"] = oldController;

                return sw.GetStringBuilder().ToString();
            }
        }
        catch (Exception ex)
        {
            Elmah.ErrorSignal.FromCurrentContext().Raise(ex);

            throw ex;
        }
    }

Essentially what this does is take a controller, such as AccountController and modify it to think it's an EmailController so that the code will look in the Views/Email folder. It's necessary to do this because the FindView method doesn't take a straight up path as a parameter, it wants a ControllerContext.

Once done rendering the string, it returns the AccountController back to its initial state to be used by the Response object.

For not-too-complicated objects you could use JSON:

var obj1 = { food: 'pizza', car: 'ford' }
var obj2 = { animal: 'dog', car: 'chevy'}
var objMerge;

objMerge = JSON.stringify(obj1) + JSON.stringify(obj2);

// {"food": "pizza","car":"ford"}{"animal":"dog","car":"chevy"}

objMerge = objMerge.replace(/\}\{/, ","); //  \_ replace with comma for valid JSON

objMerge = JSON.parse(objMerge); // { food: 'pizza', animal: 'dog', car: 'chevy'}
// Of same keys in both objects, the last object's value is retained_/

Mind you that in this example "}{" must not occur within a string!

I found that this question was still relevant but not clearly answered in my case.

Using SQL Server 2012 with an orphaned SQL_USER this was the fix;

USE databasename                      -- The database I had recently attached
EXEC sp_change_users_login 'Report'   -- Display orphaned users
EXEC sp_change_users_login 'Auto_Fix', 'UserName', NULL, 'Password'

You can select a child like

TextView tv = (TextView)lv.getChildAt(0);
tv.setTextColor(Color.RED);
tv.setTextSize(12);    

Unfortunately, the MinGW-w64 installer you used sometimes has this issue. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).

Anyways, if you're already planning on using MSYS2, there's no need for that installer.

1. Download MSYS2 from this page (choose 32 or 64-bit according to what version of Windows you are going to use it on, not what kind of executables you want to build, both versions can build both 32 and 64-bit binaries).

2. After the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit or MSYS2 32-bit in the Start menu. Update MSYS2 according to the wiki (although I just do a pacman -Syu, ignore all errors and close the window and open a new one, this is not recommended and you should do what the wiki page says).

3. Install a toolchain

   a) for 32-bit:

   pacman -S mingw-w64-i686-gcc
   

   b) for 64-bit:

   pacman -S mingw-w64-x86_64-gcc
   

4. install any libraries/tools you may need. You can search the repositories by doing

   pacman -Ss name_of_something_i_want_to_install
   

   e.g.

   pacman -Ss gsl
   

   and install using

   pacman -S package_name_of_something_i_want_to_install
   

   e.g.

   pacman -S mingw-w64-x86_64-gsl
   

   and from then on the GSL library is automatically found by your MinGW-w64 64-bit compiler!

5. Open a MinGW-w64 shell:

   a) To build 32-bit things, open the "MinGW-w64 32-bit Shell"

   b) To build 64-bit things, open the "MinGW-w64 64-bit Shell"

6. Verify that the compiler is working by doing

   gcc -v
   

If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add <MSYS2 root>/mingw32/bin or <MSYS2 root>/mingw64/bin to your PATH.

After cleaning the string, you can match non-whitespace characters or word-boundaries.

Here are two simple regular expressions to capture words in a string:

• Sequence of non-white-space characters: /\S+/g
• Valid characters between word boundaries: /\b[a-z\d]+\b/g

The example below shows how to retrieve the word count from a string, by using these capturing patterns.

The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.</textarea><br />_x000D_

Given:

public enum PersonType {
    COOL_GUY(1),
    JERK(2);

    private final int typeId;
    private PersonType(int typeId) {
        this.typeId = typeId;
    }

    public final int getTypeId() {
        return typeId;
    }

    public static PersonType findByTypeId(int typeId) {
        for (PersonType type : values()) {
            if (type.typeId == typeId) {
                return type;
            }
        }
        return null;
    }
}

For me, this typically aligns with a look-up table in a database (for rarely-updated tables only).

However, when I try to use findByTypeId in a switch statement (from, most likely, user input)...

int userInput = 3;
PersonType personType = PersonType.findByTypeId(userInput);
switch(personType) {
case COOL_GUY:
    // Do things only a cool guy would do.
    break;
case JERK:
    // Push back. Don't enable him.
    break;
default:
    // I don't know or care what to do with this mess.
}

...as others have stated, this results in an NPE @ switch(personType) {. One work-around (i.e., "solution") I started implementing was to add an UNKNOWN(-1) type.

public enum PersonType {
    UNKNOWN(-1),
    COOL_GUY(1),
    JERK(2);
    ...
    public static PersonType findByTypeId(int id) {
        ...
        return UNKNOWN;
    }
}

Now, you don't have to do null-checking where it counts and you can choose to, or not to, handle UNKNOWN types. (NOTE: -1 is an unlikely identifier in a business scenario, but obviously choose something that makes sense for your use-case).

Login as sys user in sql*plus. Then do this query:

select * from v$version; 

or

select * from product_component_version;

go to iis -> application pools -> find your application pool used in application -> click it and then click 'Advance Settings' in Actions panel. Find 'Identity' property and change it to localsystem.

please check the following code, it can help

 public class CountSpace {

    public static void main(String[] args) {

        String word = "S N PRASAD RAO";
        String data[];int k=0;
        data=word.split("");
        for(int i=0;i<data.length;i++){
            if(data[i].equals(" ")){
                k++;
            }

        }
        System.out.println(k);

    }
}

Try using now.date() to get a Date object rather than a DateTime.

If that doesn't work, then converting that to a string should work:

now = datetime.datetime(2009,5,5)
str_now = now.date().isoformat()
cursor.execute('INSERT INTO table (name, id, datecolumn) VALUES (%s,%s,%s)', ('name',4,str_now))

Update 2020:

You can now use Modern ECMAScript syntax thanks to V8 Runtime.

You can use includes():

var grade = itemResponse.getResponse();
if(grade.includes("9th")){do something}

git remote add => ADDS a new remote.

git remote set-url => UPDATES existing remote.

1. The remote name that comes after add is a new remote name that did not exist prior to that command.
2. The remote name that comes after set-url should already exist as a remote name to your repository.

git remote add myupstream someurl => myupstream remote name did not exist now creating it with this command.

git remote set-url upstream someurl => upstream remote name already exist i'm just changing it's url.

git remote add myupstream https://github.com/nodejs/node => **ADD** If you don't already have upstream
git remote set-url upstream https://github.com/nodejs/node # => **UPDATE** url for upstream

You just need the jQuery UI effects-core (13KB), to enable the duration of the adding (just like Omar Tariq it pointed out)

Here a code that works with windows office 2010. This script will ask you for input filtered range of cells and then the paste range.

Please, both ranges should have the same number of cells.

Sub Copy_Filtered_Cells()

Dim from As Variant
Dim too As Variant
Dim thing As Variant
Dim cell As Range

'Selection.SpecialCells(xlCellTypeVisible).Select

    'Set from = Selection.SpecialCells(xlCellTypeVisible)
    Set temp = Application.InputBox("Copy Range :", Type:=8)
    Set from = temp.SpecialCells(xlCellTypeVisible)
    Set too = Application.InputBox("Select Paste range selected cells ( Visible cells only)", Type:=8)



    For Each cell In from
        cell.Copy
        For Each thing In too
            If thing.EntireRow.RowHeight > 0 Then
                thing.PasteSpecial
                Set too = thing.Offset(1).Resize(too.Rows.Count)
                Exit For
            End If
        Next
    Next


End Sub

See jQuery.scroll(). You can bind this to the window element to get your desired event hook.

On scroll, then simply check your scroll position:

$(window).scroll(function() {
  var scrollTop = $(window).scrollTop();
  if ( scrollTop > $(headerElem).offset().top ) { 
    // display add
  }
});

See if the plugin has a 'skip' configuration parameter. Nearly all do. if it does, just add it to a declaration in the child:

<plugin>
   <groupId>group</groupId>
   <artifactId>artifact</artifactId>
   <configuration>
     <skip>true</skip>
   </configuration>
</plugin>

If not, then use:

<plugin>    
<groupId>group</groupId>   
 <artifactId>artifact</artifactId>    
<executions>
     <execution>
       <id>TheNameOfTheRelevantExecution</id>
       <phase>none</phase>
     </execution>    
</executions>  
</plugin>

Replace the desired hyphen with an underscore; it will automatically be rendered as a hyphen:

@Html.ActionLink("Edit", "edit", "markets",
    new { id = 1 },
    new {@class="ui-btn-right", data_icon="gear"})

becomes:

<form action="markets/Edit/1" class="ui-btn-right" data-icon="gear" .../>

Just a note: if you use arrow functions you don't need the const that = this part. It might look like this:

fetch('http://jsonplaceholder.typicode.com/posts') 
  .then((response) => { return response.json(); }) 
  .then((myJson) => { 
     this.setState({data: myJson}); // for example
});

/var/www/html is just the default root folder of the web server. You can change that to be whatever folder you want by editing your apache.conf file (usually located in /etc/apache/conf) and changing the DocumentRoot attribute (see http://httpd.apache.org/docs/current/mod/core.html#documentroot for info on that)

Many hosts don't let you change these things yourself, so your mileage may vary. Some let you change them, but only with the built in admin tools (cPanel, for example) instead of via a command line or editing the raw config files.

Not sure if it's related, but seeing that you're running some three20 libraries, you may want to check this post on their website: http://three20.info/article/2011-03-10-Xcode4-Support

The easiest way i found was to create a tiny javascript function tied to your form :

function enablePath() {
    document.getElementById('select_name').disabled= "";
}

and you call it in your form here :

<form action="act.php" method="POST" name="form_name" onSubmit="enablePath();">

Or you can call it in the function you use to check your form :)

It worked for me after adding the following dependency in pom,

<dependency>
 <groupId>org.hibernate</groupId>
 <artifactId>hibernate-validator</artifactId>
 <version>4.3.0.Final</version>
</dependency>

Below is the example of searching for a keyword in the whole list and remove that item:

public class Book
{
  public int BookId { get; set; }
  public DateTime CreatedDate { get; set; }
  public string Text { get; set; }
  public string Autor { get; set; }
  public string Source { get; set; }
}

If you want to remove a book that contains some keyword in the Text property, you can create a list of keywords and remove it from list of books:

List<Book> listToSearch = new List<Book>()
   {
        new Book(){
            BookId = 1,
            CreatedDate = new DateTime(2014, 5, 27),
            Text = " test voprivreda...",
            Autor = "abc",
            Source = "SSSS"

        },
        new Book(){
            BookId = 2,
            CreatedDate = new DateTime(2014, 5, 27),
            Text = "here you go...",
            Autor = "bcd",
            Source = "SSSS"


        }
    };

var blackList = new List<string>()
            {
                "test", "b"
            }; 

foreach (var itemtoremove in blackList)
    {
        listToSearch.RemoveAll(p => p.Source.ToLower().Contains(itemtoremove.ToLower()) || p.Source.ToLower().Contains(itemtoremove.ToLower()));
    }


return listToSearch.ToList();

It seems that in lollipop and up (or maybe just a different WebView Version) that calling cprcrack's onHideCustomView() method does not work. It works if it is called from the exit fullscreen button but when you specifically call the method it will only exit fullscreen but the webView stays blank. A way around it is to simply add these lines of code to onHideCustomView():

String js = "javascript:";
js += "var _ytrp_html5_video = document.getElementsByTagName('video')[0];";
js += "_ytrp_html5_video.webkitExitFullscreen();";
webView.loadUrl(js);

This will notify the webView that fullscreen has exited.

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.

ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.

The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).

A better option

Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses (and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.

I prefer this

WHERE CASE WHEN my_col LIKE '%val1%' THEN 1    
           WHEN my_col LIKE '%val2%' THEN 1
           WHEN my_col LIKE '%val3%' THEN 1
           ELSE 0
           END = 1

I'm not saying it's optimal but it works and it's easily understood. Most of my queries are adhoc used once so performance is generally not an issue for me.

You can (should) use CROSS JOIN. Following query will be equivalent to yours:

SELECT 
   table1.columnA
 , table2.columnA
FROM table1 
CROSS JOIN table2
WHERE table1.columnA = 'Some value'

or you can even use INNER JOIN with some always true conditon:

FROM table1 
INNER JOIN table2 ON 1=1

Here is my solution:

dependencies: Gmaps.js, jQuery

var Maps = function($) {
   var lost_addresses = [],
       geocode_count  = 0;

   var addMarker = function() { console.log('Marker Added!') };

   return {
     getGecodeFor: function(addresses) {
        var latlng;
        lost_addresses = [];
        for(i=0;i<addresses.length;i++) {
          GMaps.geocode({
            address: addresses[i],
            callback: function(response, status) {
              if(status == google.maps.GeocoderStatus.OK) {
                addMarker();
              } else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
                lost_addresses.push(addresses[i]);
              }

               geocode_count++;
               // notify listeners when the geocode is done
               if(geocode_count == addresses.length) {
                 $.event.trigger({ type: 'done:geocoder' });
               }
            }
          });
        }
     },
     processLostAddresses: function() {
       if(lost_addresses.length > 0) {
         this.getGeocodeFor(lost_addresses);
       }
     }
   };
}(jQuery);

Maps.getGeocodeFor(address);

// listen to done:geocode event and process the lost addresses after 1.5s
$(document).on('done:geocode', function() {
  setTimeout(function() {
    Maps.processLostAddresses();
  }, 1500);
});

This is not only applicable in Modernizer. I see some site implement like below to check whether it has javascript support or not.

<body class="no-js">
    <script>document.body.classList.remove('no-js');</script>
    ...
</body>

If javascript support is there, then it will remove no-js class. Otherwise no-js will remain in the body tag. Then they control the styles in the css when no javascript support.

.no-js .some-class-name {

}

The SSL is not properly configured. Those trustAnchor errors usually mean that the trust store cannot be found. Check your configuration and make sure you are actually pointing to the trust store and that it is in place.

Make sure you have a -Djavax.net.ssl.trustStore system property set and then check that the path actually leads to the trust store.

You can also enable SSL debugging by setting this system property -Djavax.net.debug=all. Within the debug output you will notice it states that it cannot find the trust store.

You have to import the font in your stylesheet like this:

@font-face{
    font-family: "Thonburi-Bold";
    src: url('Thonburi-Bold.ttf'),
    url('Thonburi-Bold.eot'); /* IE */
}

I was able to make parent window disable. However making the pop-up always keep raised didn't work. Below code works even for frame tags. Just add id and class property to frame tag and it works well there too.

In parent window use:

<head>    
<style>
.disableWin{
     pointer-events: none;
}
</style>
<script type="text/javascript">
    function openPopUp(url) {
      disableParentWin(); 
      var win = window.open(url);
      win.focus();
      checkPopUpClosed(win);
    }
    /*Function to detect pop up is closed and take action to enable parent window*/
   function checkPopUpClosed(win) {
         var timer = setInterval(function() {
              if(win.closed) {
                  clearInterval(timer);                  
                  enableParentWin();
              }
          }, 1000);
     }
     /*Function to enable parent window*/ 
     function enableParentWin() {
          window.document.getElementById('mainDiv').class="";
     }
     /*Function to enable parent window*/ 
     function disableParentWin() {
          window.document.getElementById('mainDiv').class="disableWin";
     }

</script>
</head>

<body>
<div id="mainDiv class="">
</div>
</body>    

I had a need for an extended version of this: instead of embedding a single number in a string, I needed to generate a series of file names of the form 'file1.pdf', 'file2.pdf' etc. This is how it worked:

['file' + str(i) + '.pdf' for i in range(1,4)]

I was having a similar issue as my breakpoints in project(B) were not being hit. My solution was to rebuild project(B) then debug project(A) as the dlls needed to be updated.

Visual studio should allow you to debug into an external library.

While this may be an old question, the problem is still occurring these days, and the exact question is still not answered properly.

It is important to note that some projects have multiple classes with a main method.

In my case, I could run the project via the main class, but I could not run a particular other class that had a main method. The only thing that helped me was refactoring the class and renaming it. I've tried:

• restart NetBeans
• re-open the project
• clear NetBeans cache
• delete the file and create a new one with same name and contents
• delete the file and create a new one with same name but very simple contents with only main method and print out message
• rename the class (refactor) so a temp name and back
• delete the project and create a new one with the same sources

The only thing that let me run this class is renaming it permanently. I think this must be some kind of a NetBeans bug.

Edit: Another thing that did help was completely uninstall Netbeans, wipe cache and any configuration files. It so happened that a newer Netbeans version was available so I installed it. But the old one would have probably worked too.

Yes, the result is always truncated towards zero. It will round towards the smallest absolute value.

-5 / 2 = -2
 5 / 2 =  2

For unsigned and non-negative signed values, this is the same as floor (rounding towards -Infinity).

The server_name^docs directive is used to identify virtual hosts, they're not used to set the binding.

netstat tells you that nginx listens on 0.0.0.0:80 which means that it will accept connections from any IP.

If you want to change the IP nginx binds on, you have to change the listen^docs rule.
So, if you want to set nginx to bind to localhost, you'd change that to:

listen 127.0.0.1:80;

In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).

Well, you can use a regular expression to find the cases where "Milan" isn't followed by "Vasic":

Milan(?! Vasic)

and replace that by the full name:

String.replaceAll("Milan(?! Vasic)", "Milan Vasic")

The (?!...) part is a negative lookahead which ensures that whatever matches isn't followed by the part in parentheses. It doesn't consume any characters in the match itself.

Alternatively, you can simply insert (well, technically replacing a zero-width match) the last name after the first name, unless it's followed by the last name already. This looks similar, but uses a positive lookbehind as well:

(?<=Milan)(?! Vasic)

You can replace this by just " Vasic" (note the space at the start of the string):

String.replaceAll("(?<=Milan)(?! Vasic)", " Vasic")

You can try those things out here for example.

From http://ora-01438.ora-code.com/ (the definitive resource outside of Oracle Support):

ORA-01438: value larger than specified precision allowed for this column
Cause: When inserting or updating records, a numeric value was entered that exceeded the precision defined for the column.
Action: Enter a value that complies with the numeric column's precision, or use the MODIFY option with the ALTER TABLE command to expand the precision.

http://ora-06512.ora-code.com/:

ORA-06512: at stringline string
Cause: Backtrace message as the stack is unwound by unhandled exceptions.
Action: Fix the problem causing the exception or write an exception handler for this condition. Or you may need to contact your application administrator or DBA.

If you're looking to reduce clutter, consider

var lst = new List<string> { "foo", "bar" };

This uses two features of C# 3.0: type inference (the var keyword) and the collection initializer for lists.

Alternatively, if you can make do with an array, this is even shorter (by a small amount):

var arr = new [] { "foo", "bar" };

How about alias gcc99= gcc -std=c99?

Well, the straightforward method is to create an appropriate class/structure which holds all your parameter values and pass that to the thread.

Another solution in VB10 is to use the fact that lambdas create a closure, which basically means the compiler doing the above automatically for you:

Dim evaluator As New Thread(Sub()
                                testthread(goodList, 1)
                            End Sub)

There's also a C standard built-in library to get command line arguments: getopt

You can check it on Wikipedia or in Argument-parsing helpers for C/Unix.

Update: Turns out that this method, while following STL idioms well, is actually surprisingly inefficient! Don't do this with large files. (See: http://insanecoding.blogspot.com/2011/11/how-to-read-in-file-in-c.html)

You can make a streambuf iterator out of the file and initialize the string with it:

#include <string>
#include <fstream>
#include <streambuf>

std::ifstream t("file.txt");
std::string str((std::istreambuf_iterator<char>(t)),
                 std::istreambuf_iterator<char>());

Not sure where you're getting the t.open("file.txt", "r") syntax from. As far as I know that's not a method that std::ifstream has. It looks like you've confused it with C's fopen.

Edit: Also note the extra parentheses around the first argument to the string constructor. These are essential. They prevent the problem known as the "most vexing parse", which in this case won't actually give you a compile error like it usually does, but will give you interesting (read: wrong) results.

Following KeithB's point in the comments, here's a way to do it that allocates all the memory up front (rather than relying on the string class's automatic reallocation):

#include <string>
#include <fstream>
#include <streambuf>

std::ifstream t("file.txt");
std::string str;

t.seekg(0, std::ios::end);   
str.reserve(t.tellg());
t.seekg(0, std::ios::beg);

str.assign((std::istreambuf_iterator<char>(t)),
            std::istreambuf_iterator<char>());

I had accidentally enabled a different mode for the tab key. Fixed it by pressing Ctrl+Shift(for Mac only)+M.

From the Visual Studio Code Keybinding docs:

| Key      | Command                                 | Command id                       |
| Ctrl + M | Toggle Use of Tab Key for Setting Focus | editor.action.toggleTabFocusMode |

The current tab control mode should also show up in the status bar:

ESC and CTRL-BREAK did not work for me just now. But CTRL-ESC worked!? No idea why, but I thought I would throw it out there in case it helps someone else. (I had forgotten i = i + 1 in my loop...)

try to run the code below

- (void)viewDidLoad {
    [super viewDidLoad];
    UIWindow *w = [[UIApplication sharedApplication] keyWindow];
    UIView *v = [w.subviews objectAtIndex:0];

    NSLog(@"%@", NSStringFromCGRect(v.frame));
    NSLog(@"%@", NSStringFromCGRect(v.bounds));
}

the output of this code is:

case device orientation is Portrait

{{0, 0}, {768, 1024}}
{{0, 0}, {768, 1024}}

case device orientation is Landscape

{{0, 0}, {768, 1024}}
{{0, 0}, {1024, 768}}

obviously, you can see the difference between frame and bounds

Instruction how to create a bootstrap navbar with a logo which is larger than the default height (50px):

Example with a logo 100px x 100px, standard CSS:

1. Compute the height and (padding top + padding bottom) of the logo. Here 120px (100px height + padding top (10px) + padding bottom (10px))

2. Goto bootstrap / customize. Set instead of navbar height 50px > 120px (50 + 70) and navbar-collapse-max-height from 340px to 410px (340 + 70). Download css.

3. In this example I use this navbar. In navbar-brand:

     <div class="navbar-header">
       ...
       </button>
       <a class="navbar-brand myLogo" href="#">
         <img src="yourLogo.jpg" />
       </a>
     </div>...
   

   add a class, for example myLogo, and an img (your logo)

   <a class="navbar-brand myLogo" href="#"><img src="yourLogo.jpg" /></a>.

4. Add CSS

   .myLogo { padding: 10px; }

5. Adequate to other sizes.

Example

Or, you can ignore the error:

declare
    column_exists exception;
    pragma exception_init (column_exists , -01430);
begin
    execute immediate 'ALTER TABLE db.tablename ADD columnname NVARCHAR2(30)';
    exception when column_exists then null;
end;

Poster is asking for an integer value of MS since Epoch, not a time or S since Epoch.

For that, you need to use NOW(3) which gives you time in fractional seconds to 3 decimal places (ie MS precision): 2020-02-13 16:30:18.236

Then UNIX_TIMESTAMP(NOW(3)) to get the time to fractional seconds since epoc: 1581611418.236

Finally, FLOOR(UNIX_TIMESTAMP(NOW(3))*1000) to get it to a nice round integer, for ms since epoc: 1581611418236

Make it a MySQL Function:

CREATE FUNCTION UNIX_MS() RETURN BIGINT DETERMINISTIC
BEGIN
    RETURN FLOOR(UNIX_TIMESTAMP(NOW(3))*1000);
END

Now run SELECT UNIX_MS();

Note: this was all copied by hand so if there are mistakes feel free to fix ;)

Found this thread while I was looking for a solution to the exact problem described in the original post. None of the answers met my situation entirely, however. Brody's answer was pretty close. Here is my situation and solution I found to it.

I have two ILists of the same type returned by NHibernate and have emerged the two IList into one, hence the need for sorting.

Like Brody said I implemented an ICompare on the object (ReportFormat) which is the type of my IList:

 public class FormatCcdeSorter:IComparer<ReportFormat>
    {
       public int Compare(ReportFormat x, ReportFormat y)
        {
           return x.FormatCode.CompareTo(y.FormatCode);
        }
    }

I then convert the merged IList to an array of the same type:

ReportFormat[] myReports = new ReportFormat[reports.Count]; //reports is the merged IList

Then sort the array:

Array.Sort(myReports, new FormatCodeSorter());//sorting using custom comparer

Since one-dimensional array implements the interface System.Collections.Generic.IList<T>, the array can be used just like the original IList.

If you want to select the last child and need to be specific on the element type you can use the selector last-of-type

Here is an example:

$("div p:last-of-type").css("border", "3px solid red");
$("div span:last-of-type").css("border", "3px solid red");

<div id="example">
            <p>This is paragraph 1</p>
            <p>This is paragraph 2</p>
            <span>This is paragraph 3</span>
            <span>This is paragraph 4</span>
            <p>This is paragraph 5</p>
        </div>

In the example above both Paragraph 4 and Paragraph 5 will have a red border since Paragraph 5 is the last element of "p" type in the div and Paragraph 4 is the last "span" in the div.

You see the same symptoms if you are working in Xamarin Studio and you are referencing a portable library for which you need to do the PCL bait and switch trick for. This occurs if the referencing project is out of date with respect to the referenced library. I found that I had updated my common library to a newer framework, updated my packages but hadn't updated my iOS packages to match. Updating the packages solved this error for me.

The answer is:

gcc --version

Rather than searching on forums, for any possible option you can always type:

gcc --help

haha! :)

Same as the updating existing collection field, $set will add a new fields if the specified field does not exist.

Check out this example:

> db.foo.find()
> db.foo.insert({"test":"a"})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> item = db.foo.findOne()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> db.foo.update({"_id" :ObjectId("4e93037bbf6f1dd3a0a9541a") },{$set : {"new_field":1}})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "new_field" : 1, "test" : "a" }

EDIT:

In case you want to add a new_field to all your collection, you have to use empty selector, and set multi flag to true (last param) to update all the documents

db.your_collection.update(
  {},
  { $set: {"new_field": 1} },
  false,
  true
)

EDIT:

In the above example last 2 fields false, true specifies the upsert and multi flags.

Upsert: If set to true, creates a new document when no document matches the query criteria.

Multi: If set to true, updates multiple documents that meet the query criteria. If set to false, updates one document.

This is for Mongo versions prior to 2.2. For latest versions the query is changed a bit

db.your_collection.update({},
                          {$set : {"new_field":1}},
                          {upsert:false,
                          multi:true}) 

OCV goes out of its way to make sure you can't do this without knowing the element type, but if you want an easily codable but not-very-efficient way to read it type-agnostically, you can use something like

double val=mean(someMat(Rect(x,y,1,1)))[channel];

To do it well, you do have to know the type though. The at<> method is the safe way, but direct access to the data pointer is generally faster if you do it correctly.

Try this one:

    <textarea cols='60' rows='8'>This is my statement one.&#13;&#10;This is my statement2</textarea>


 Line Feed and 
 Carriage Return are HTML entities^wikipedia. This way you are actually parsing the new line ("\n") rather than displaying it as text.

Many developers include files by pointing to a remote URL, even if the file is within the local system. For example:

<php include("http://example.com/includes/example_include.php"); ?>

With allow_url_include disabled, this method does not work. Instead, the file must be included with a local path, and there are three methods of doing this:

By using a relative path, such as ../includes/example_include.php. By using an absolute path (also known as relative-from-root), such as /home/username/example.com/includes/example_include.php.

By using the PHP environment variable $_SERVER['DOCUMENT_ROOT'], which returns the absolute path to the web root directory. This is by far the best (and most portable) solution. The following example shows the environment variable in action.

Example Include

<?php include($_SERVER['DOCUMENT_ROOT']."/includes/example_include.php"); ?>

If you want a "capture/streamer in a box" component, there are several out there as others have mentioned.

If you want to get down to the low-level control over it all, you'll need to use DirectShow as thealliedhacker points out. The best way to use DirectShow in C# is through the DirectShow.Net library - it wraps all of the DirectShow COM APIs and includes many useful shortcut functions for you.

In addition to capturing and streaming, you can also do recording, audio and video format conversions, audio and video live filters, and a whole lot of stuff.

Microsoft claims DirectShow is going away, but they have yet to release a new library or API that does everything that DirectShow provides. I suspect many of the latest things they have released are still DirectShow under the hood. Because of its status at Microsoft, there aren't a whole lot of books or references on it other than MSDN and what you can find on forums. Last year when we started a project using it, the best book on the subject - Programming Microsoft DirectShow - was out of print and going for around $350 for a used copy!

You can use

$_FILES['filename']['error'];

If any type of error occurs then it returns 'error' else 1,2,3,4 or 1 if done

1 : if file size is over limit .... You can find other options by googling

Given that commonly 1 = true and 0 = false, all you need to do is count the number of rows, and cast to a boolean.

Hence, your posted code only needs a COUNT() function added:

SELECT CAST(COUNT(1) AS BIT) AS Expr1
FROM [User]
WHERE (UserID = 20070022)

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

I know this thread is old, but...

If you're using html encoding (like AntiXSS), the previous answers will not work. The break tags will be rendered as text, rather than applying a carriage return. You can wrap your asp label in a pre tag, and it will display with whatever line breaks are set from the code behind.

Example:

<pre style="width:600px;white-space:pre-wrap;"><asp:Label ID="lblMessage" Runat="server" visible ="true"/></pre>

The function on this page will return a rectangle with the top, left, height and width co ordinates of a passed element relative to the browser view port.

    localToGlobal: function( _el ) {
       var target = _el,
       target_width = target.offsetWidth,
       target_height = target.offsetHeight,
       target_left = target.offsetLeft,
       target_top = target.offsetTop,
       gleft = 0,
       gtop = 0,
       rect = {};

       var moonwalk = function( _parent ) {
        if (!!_parent) {
            gleft += _parent.offsetLeft;
            gtop += _parent.offsetTop;
            moonwalk( _parent.offsetParent );
        } else {
            return rect = {
            top: target.offsetTop + gtop,
            left: target.offsetLeft + gleft,
            bottom: (target.offsetTop + gtop) + target_height,
            right: (target.offsetLeft + gleft) + target_width
            };
        }
    };
        moonwalk( target.offsetParent );
        return rect;
}

Assuming you have Files a.txt and b.txt with

cat a.txt
a
b
c

cat b.txt

Keep in mind NR and FNR are awk built-in variables. NR - Gives the total number of records processed. (in this case both in a.txt and b.txt) FNR - Gives the total number of records for each input file (records in either a.txt or b.txt)

awk 'NR==FNR{a[$0];}{if($0 in a)print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
a.txt 1 1 a
a.txt 2 2 b
a.txt 3 3 c
a.txt 4 4 d
a.txt 5 5 1
a.txt 6 6 3
a.txt 7 7 5
b.txt 8 1 a
b.txt 9 2 1

lets Add "next" to skip the first matched with NR==FNR

in b.txt and in a.txt

awk 'NR==FNR{a[$0];next}{if($0 in a)print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
b.txt 8 1 a
b.txt 9 2 1

in b.txt but not in a.txt

 awk 'NR==FNR{a[$0];next}{if(!($0 in a))print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
b.txt 10 3 2
b.txt 11 4 6

Static blocks are used for initializaing the code and will be executed when JVM loads the class.Refer to the below link which gives the detailed explanation. http://www.jusfortechies.com/java/core-java/static-blocks.php

I had the same issue with the filtered index and my inserts and updates were failing. All I did was to change the stored procedure that had the insert and update statement to:

create procedure abc
()
AS
BEGIN
SET NOCOUNT ON
SET NUMERIC_ROUNDABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON 
SET ANSI_WARNINGS ON 
SET ANSI_PADDING ON 
end

I fixed mine by adding these lines on my IIS webconfig.

<httpErrors>
    <remove statusCode="405" subStatusCode="-1" />
    <error statusCode="405" prefixLanguageFilePath="" path="/my-page.htm" responseMode="ExecuteURL" />
</httpErrors>

Basically, what is happening is that your user is either closing the browser tab, or is navigating away to a different page, before communication was complete. Your webserver (Jetty) generates this exception because it is unable to send the remaining bytes.

org.eclipse.jetty.io.EofException: null
! at org.eclipse.jetty.http.HttpGenerator.flushBuffer(HttpGenerator.java:914)
! at org.eclipse.jetty.http.HttpGenerator.complete(HttpGenerator.java:798)
! at org.eclipse.jetty.server.AbstractHttpConnection.completeResponse(AbstractHttpConnection.java:642)
! 

This is not an error on your application logic side. This is simply due to user behavior. There is nothing wrong in your code per se.

There are two things you may be able to do:

1. Ignore this specific exception so that you don't log it.
2. Make your code more efficient/packed so that it transmits less data. (Not always an option!)

For me, password = admin, worked. I installed it using pacman, Arch (Manjaro KDE).

NB: MariaDB was already installed, as a dependency of Amarok.

I agree with sunetos that you'll have to use the $.ajax function in order to pass request headers. In order to do that, you'll have to write a function for the beforeSend event handler, which is one of the $.ajax() options. Here's a quick sample on how to do that:

<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
    <script type="text/javascript">
      $(document).ready(function() {
        $.ajax({
          url: 'service.svc/Request',
          type: 'GET',
          dataType: 'json',
          success: function() { alert('hello!'); },
          error: function() { alert('boo!'); },
          beforeSend: setHeader
        });
      });

      function setHeader(xhr) {
        xhr.setRequestHeader('securityCode', 'Foo');
        xhr.setRequestHeader('passkey', 'Bar');
      }
    </script>
  </head>
  <body>
    <h1>Some Text</h1>
  </body>
</html>

If you run the code above and watch the traffic in a tool like Fiddler, you'll see two requests headers passed in:

• securityCode with a value of Foo
• passkey with a value of Bar

The setHeader function could also be inline in the $.ajax options, but I wanted to call it out.

Hope this helps!

You can define a static constructor for the class that will check that the type T is an enum and throw an exception if it is not. This is the method mentioned by Jeffery Richter in his book CLR via C#.

internal sealed class GenericTypeThatRequiresAnEnum<T> {
    static GenericTypeThatRequiresAnEnum() {
        if (!typeof(T).IsEnum) {
        throw new ArgumentException("T must be an enumerated type");
        }
    }
}

Then in the parse method, you can just use Enum.Parse(typeof(T), input, true) to convert from string to the enum. The last true parameter is for ignoring case of the input.

Eclipse shows hidden files in the "Navigator" view. You can add that via Window->Show View->Navigator.

According to the API, the headers can all be passed in using requests.get:

import requests
r=requests.get("http://www.example.com/", headers={"content-type":"text"})

To check a commit out (nb you are looking at the past!).

• git checkout "commmitHash"

To brutally restart from a commit and delete those later branches that you probably messed up.

• git reset --hard "commmitHash"

you can use super while extending Exception

if (pass.length() < minPassLength)
    throw new InvalidPassException("The password provided is too short");
 } catch (NullPointerException e) {
    throw new InvalidPassException("No password provided", e);
 }


// A custom business exception
class InvalidPassException extends Exception {

InvalidPassException() {

}

InvalidPassException(String message) {
    super(message);
}
InvalidPassException(String message, Throwable cause) {
   super(message, cause);
}

}

}

I am no expert at this (and this page was very helpful along with http://mywiki.wooledge.org/UsingFind)

Just noticed -path is for a path that fully matches the string/path that comes just after find (. in theses examples) where as -name matches all basenames.

find . -path ./.git  -prune -o -name file  -print

blocks the .git directory in your current directory ( as your finding in . )

find . -name .git  -prune -o -name file  -print

blocks all .git subdirectories recursively.

Note the ./ is extremely important!! -path must match a path anchored to . or whatever comes just after find if you get matches with out it (from the other side of the or '-o') there probably not being pruned! I was naively unaware of this and it put me of using -path when it is great when you don't want to prune all subdirectory with the same basename :D

In my case EXC_I386_GPFLT was caused by missing return value in the property getter. Like this:

- (CppStructure)cppStructure
{
    CppStructure data;
    data.a = self.alpha;
    data.b = self.beta;

    return data; // this line was missing
}

From Django 1.8,

from django.db.models.functions import Length

Name.objects.annotate(alias_length=Length('alias')).filter(alias_length__gt=0)

just for the record you can always compare using JSON.stringify

const arr = [1,2,3]; expect(JSON.stringify(arr)).toBe(JSON.stringify([1,2,3])); expect(JSON.stringify(arr)).toEqual(JSON.stringify([1,2,3]));

It's all meter of taste, this will also work for complex literal objects

This could be a issue in mvn home path in IntellijIdea IDE. For me it worked out when I set the mvn home directory correctly.

You can use this method.

    public static File getRobotCacheFile(Context context) throws IOException {
        File cacheFile = new File(context.getCacheDir(), "robot.png");
        try {
            InputStream inputStream = context.getAssets().open("robot.png");
            try {
                FileOutputStream outputStream = new FileOutputStream(cacheFile);
                try {
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = inputStream.read(buf)) > 0) {
                        outputStream.write(buf, 0, len);
                    }
                } finally {
                    outputStream.close();
                }
            } finally {
                inputStream.close();
            }
        } catch (IOException e) {
            throw new IOException("Could not open robot png", e);
        }
        return cacheFile;
    }

You should never use InputStream.available() in such cases. It returns only bytes that are buffered. Method with .available() will never work with bigger files and will not work on some devices at all.

In Kotlin (;D):

@Throws(IOException::class)
fun getRobotCacheFile(context: Context): File = File(context.cacheDir, "robot.png")
    .also {
        it.outputStream().use { cache -> context.assets.open("robot.png").use { it.copyTo(cache) } }
    }

Elaborating Alex Volovoy's answer a little more -

in case u are getting this problem with fragments, getActivity() works fine to get the context

In Other Cases:

If you don't want to use-

myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//not recommend

then make a function like this in your OutsideClass -

public void gettingContext(Context context){
    real_context = context;//where real_context is a global variable of type Context
}

Now,in your main activity when ever you make a new OutsideClass call the above method immediately after you define the OutsideClass giving the activity's context as argument. Also in your main activity make a function-

public void startNewActivity(final String activity_to_start) {
    if(activity_to_start.equals("ACTIVITY_KEY"));
    //ACTIVITY_KEY-is a custom key,just to
    //differentiate different activities
    Intent i = new Intent(MainActivity.this, ActivityToStartName.class);
    activity_context.startActivity(i);      
}//you can make a if-else ladder or use switch-case

now come back to your OutsideClass,and to start new activity do something like this-

@Override
public void onClick(View v) {
........
case R.id.any_button:

            MainActivity mainAct = (MainActivity) real_context;             
            mainAct.startNewActivity("ACTIVITY_KEY");                   

        break;
    }
........
}

This way you will be able to start different activities called from different OutsideClass without messing up with flags.

Note-Try not to cache context object via constructor for fragment(with adapter,its fine).A fragment should have a empty constructor otherwise application crashes in some scenarios.

remember to call

OutsideClass.gettingContext(Context context);

in the onResume() function as well.

If you are using visual studio 2005 then

public void sumAverageElements(int[] arr)
{
     int size =arr.Length;
     int sum = 0;
     int average = 0;

     for (int i = 0; i < size; i++)
     {
          sum += arr[i];
     }

     average = sum / size; // sum divided by total elements in array

     Console.WriteLine("The Sum Of Array Elements Is : " + sum);
     Console.WriteLine("The Average Of Array Elements Is : " + average);
}

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

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

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

Well when you are writing a c program and want the output log to stay instead of flickering away you only need to import the stdlib.h header file and type "system("PAUSE");" at the place you want the output screen to halt.Look at the example here.The following simple c program prints the product of 5 and 6 i.e 30 to the output window and halts the output window.

#include <stdio.h>
#include <stdlib.h>
int main()
 {
      int a,b,c;
      a=5;b=6;
      c=a*b;
      printf("%d",c);
      system("PAUSE");
      return 0;
 }

Hope this helped.

What you really need is EasyClip. It will do just that and so much more...

Use this method:

 public String getUserEmail() {
    AccountManager manager = AccountManager.get(App.getInstance());
    Account[] accounts = manager.getAccountsByType("com.google");
    List<String> possibleEmails = new LinkedList<>();
    for (Account account : accounts) {
        possibleEmails.add(account.name);
    }
    if (!possibleEmails.isEmpty() && possibleEmails.get(0) != null) {
        return possibleEmails.get(0);
    }
    return "";
}

Note that this requires the GET_ACCOUNTS permission:

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

Then:

editTextEmailAddress.setText(getUserEmail());

Following up to Isaac Turner's excellent answer, I'd like put an example based on K Closest Points to the Origin using max heap.

from math import sqrt
import heapq


class MaxHeapObj(object):
    def __init__(self, val):
        self.val = val.distance
        self.coordinates = val.coordinates

    def __lt__(self, other):
        return self.val > other.val

    def __eq__(self, other):
        return self.val == other.val

    def __str__(self):
        return str(self.val)


class MinHeap(object):
    def __init__(self):
        self.h = []

    def heappush(self, x):
        heapq.heappush(self.h, x)

    def heappop(self):
        return heapq.heappop(self.h)

    def __getitem__(self, i):
        return self.h[i]

    def __len__(self):
        return len(self.h)


class MaxHeap(MinHeap):
    def heappush(self, x):
        heapq.heappush(self.h, MaxHeapObj(x))

    def heappop(self):
        return heapq.heappop(self.h).val

    def peek(self):
        return heapq.nsmallest(1, self.h)[0].val

    def __getitem__(self, i):
        return self.h[i].val


class Point():
    def __init__(self, x, y):
        self.distance = round(sqrt(x**2 + y**2), 3)
        self.coordinates = (x, y)


def find_k_closest(points, k):
    res = [Point(x, y) for (x, y) in points]
    maxh = MaxHeap()

    for i in range(k):
        maxh.heappush(res[i])

    for p in res[k:]:
        if p.distance < maxh.peek():
            maxh.heappop()
            maxh.heappush(p)

    res = [str(x.coordinates) for x in maxh.h]
    print(f"{k} closest points from origin : {', '.join(res)}")


points = [(10, 8), (-2, 4), (0, -2), (-1, 0), (3, 5), (-2, 3), (3, 2), (0, 1)]
find_k_closest(points, 3)

I am new to retrofit and I am enjoying it. So here is a simple way to understand it for those that might want to query with more than one query: The ? and & are automatically added for you.

Interface:

 public interface IService {

      String BASE_URL = "https://api.test.com/";
      String API_KEY = "SFSDF24242353434";

      @GET("Search") //i.e https://api.test.com/Search?
      Call<Products> getProducts(@Query("one") String one, @Query("two") String two,    
                                @Query("key") String key)
}

It will be called this way. Considering you did the rest of the code already.

  Call<Results> call = service.productList("Whatever", "here", IService.API_KEY);

For example, when a query is returned, it will look like this.

//-> https://api.test.com/Search?one=Whatever&two=here&key=SFSDF24242353434

To add to Reed Copsey's answer about using Task.FromResult, you can improve performance even more if you cache the already completed task since all instances of completed tasks are the same:

public static class TaskExtensions
{
    public static readonly Task CompletedTask = Task.FromResult(false);
}

With TaskExtensions.CompletedTask you can use the same instance throughout the entire app domain.

The latest version of the .Net Framework (v4.6) adds just that with the Task.CompletedTask static property

Task completedTask = Task.CompletedTask;

allow-popups: Allow opening popup windows.
allow-pointer-lock: Allow access to pointer movement and pointer lock.
allow-same-origin: Allow access to DOM objects when the iframe loaded form same origin
allow-scripts: Allow executing scripts inside iframe
allow-top-navigation: Allow navigation to top level window

Please see: http://www.whatwg.org/specs/web-apps/current-work/multipage/the-iframe-element.html#attr-iframe-sandbox

Now, consider attacker used the following code to host your site in iframe:

<iframe src="URI" sandbox></iframe>

Then, all JavaScript frame busting code will fail.

After checking all frame busing code, only this defense works in all cases:

<style id="antiClickjack">body{display:none !important;}</style>
<script type="text/javascript">
   if (self === top) {
       var antiClickjack = document.getElementById("antiClickjack");
       antiClickjack.parentNode.removeChild(antiClickjack);
   } else {
       top.location = self.location;
   }
</script>

that originally proposed by Gustav Rydstedt, Elie Bursztein, Dan Boneh, and Collin Jackson (2010)

Just for fun, here's another way:

;with counts as (
    select CustomerName, EmailAddress,
      count(*) over (partition by EmailAddress) as num
    from Customers
)
select CustomerName, EmailAddress
from counts
where num > 1

Store it in a field of type long. See Date.getTime() and new Date(long)

You can use jquery animate function for that.

$({ countNum: $('.code').html() }).animate({ countNum: 4000 }, {
        duration: 8000,
        easing: 'linear',
        step: function () {
        $('.code').html(Math.floor(this.countNum) );
        },
        complete: function () {
        $('.code').html(this.countNum);
        //alert('finished');
        }
    });

I have the same issue and solved it by reading this post, while solving it, I hitted a problem: auth failed.

And I finally solved it by using a ssh key way to authorize myself. I found the EGit offical guide very useful and I configured the ssh way successfully by refer to the Eclipse SSH Configuration section in the link provided.

Hope it helps.

TheDay maps back to some integer type. So:

printf("%s", TheDay);

Attempts to parse TheDay as a string, and will either print out garbage or crash.

printf is not typesafe and trusts you to pass the right value to it. To print out the name of the value, you'd need to create some method for mapping the enum value to a string - either a lookup table, giant switch statement, etc.

Follow these steps when deploying the Windows Service, don't lose time:

1. Run command prompt by the Admin right

2. Insure about release mode when compilling in your IDE

3. Give a type to your project installer on design view

4. Select authentication type in accordance the case

5. Insure about software dependencies: If you are using a certificate install it correctly

6. Go your console write this:

   C:\Windows\Microsoft.NET\Framework\yourRecentVersion\installutil.exe c:\yourservice.exe

there is a hidden -i argument before the exe path -i c:\ you can use -u for uninstallling

7. Look your .exe path to seem log file. You can use event viewer to observing in the feature

Another fast and easy way to semi-automate these steps is to:

1. take the JSON you want to parse and paste it here: https://app.quicktype.io/ . Change language to C# in the drop down.
2. Update the name in the top left to your class name, it defaults to "Welcome".
3. In visual studio go to Website -> Manage Packages and use NuGet to add Json.Net from Newtonsoft.

4. app.quicktype.io generated serialize methods based on Newtonsoft. Alternatively, you can now use code like:

   WebClient client = new WebClient();

   string myJSON = client.DownloadString("https://URL_FOR_JSON.com/JSON_STUFF");

   var myClass = Newtonsoft.Json.JsonConvert.DeserializeObject(myJSON);

Try this instead to only select the visible elements under the tbody:

$('tbody :visible').highlight(myArray[i]);

var img = new Image();

img.onload = function(){
  var height = img.height;
  var width = img.width;

  // code here to use the dimensions
}

img.src = url;

Try this it works

<ul class="sub-menu" type="none">
           <li class="sub-menu-list" ng-repeat="menu in list.components">
               <a class="sub-menu-link">
                   {{ menu.component }}
               </a>
           </li>
        </ul>

What you have should work. It depends on the type of data you are setting i.e. if it's a string value you need to make sure it's in quotes e.g.

var val = '@ViewBag.ForSection';

If it's an integer you need to parse it as one i.e.

var val = parseInt(@ViewBag.ForSection);

System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = @"/c -sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer"

use /c as a cmd argument to close cmd.exe once its finish processing your commands

I'm not a sqlite user, so take this with a grain of salt; most RDBM's support the ANSI standard of the INFORMATION_SCHEMA views. If you run the following query:

SELECT *
FROM INFORMATION_SCHEMA.columns
WHERE table_name = 'your table'

You should get a table which lists all of the columns in your specified table. IT may take some tweaking to get the output you want, but hopefully its a start.

Android's callOnClick() (added in API 15) can sometimes be a better choice in my experience than performClick(). If a user has selection sounds enabled, then performClick() could cause the user to hear two continuous selection sounds that are somewhat layered on top of each other which can be jarring. (One selection sound for the user's first button click, and then another for the other button's OnClickListener that you're calling via code.)

For those who do not have 4.5, Here is my library function that reads json. It requires a project reference to System.Web.Extensions.

using System.Web.Script.Serialization;

public object DeserializeJson<T>(string Json)
{
    JavaScriptSerializer JavaScriptSerializer = new JavaScriptSerializer();
    return JavaScriptSerializer.Deserialize<T>(Json);
}

Usually, json is written out based on a contract. That contract can and usually will be codified in a class (T). Sometimes you can take a word from the json and search the object browser to find that type.

Example usage:

Given the json

{"logEntries":[],"value":"My Code","text":"My Text","enabled":true,"checkedIndices":[],"checkedItemsTextOverflows":false}

You could parse it into a RadComboBoxClientState object like this:

string ClientStateJson = Page.Request.Form("ReportGrid1_cboReportType_ClientState");
RadComboBoxClientState RadComboBoxClientState = DeserializeJson<RadComboBoxClientState>(ClientStateJson);
return RadComboBoxClientState.Value;

There is a library which does exactly what you need:

import more_itertools
list(more_itertools.windowed([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15],n=3, step=3))

Out: [(1, 2, 3), (4, 5, 6), (7, 8, 9), (10, 11, 12), (13, 14, 15)]

What does res.render do and what does the html file look like?

res.render() function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.

Answering Edit 2 part.

// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');

// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');

// here you render `orders` template
response.render("orders", {orders: orders_json});

So, the template path is views/ (first part) + orders (second part) + .ejs (third part) === views/orders.ejs

Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.

For whatever reason, these answers didn't quite work for me. This is what worked for me instead:

In Vim, the :version command gives you the paths of system and user vimrc and gvimrc files (among other things), and the output looks something like this:

 system vimrc file: "$VIM/vimrc"
   user vimrc file: "$HOME/.vimrc"
    user exrc file: "$HOME/.exrc"
system gvimrc file: "$VIM/gvimrc"
  user gvimrc file: "$HOME/.gvimrc"

The one you want is user vimrc file: "$HOME/.vimrc"

So to edit the file: vim $HOME/.vimrc

Source: Open vimrc file

The Problem

I help maintain a big, complicated, messy old site in which everything (literally) is nested in multiple levels of iframes-- many of which are dynamically created and/or have a dynamic src. That creates the following challenges:

1. Any changes to the HTML structure risk breaking scripts and stylesheets that haven't been touched in years.
2. Finding and fixing all of the iframes and src documents manually would take way too much time and effort.

Of the solutions posted so far, this is the only one I've seen that overcomes challenge 1. Unfortunately, it doesn't seem to work on some iframes, and when it does, the scrolling is very glitchy (which seems to cause other bugs on the page, such as unresponsive links and form controls).

The Solution

If the above sounds anything like your situation, you may want to give the following script a try. It forgoes native scrolling and instead makes all iframes draggable within the bounds of their viewport. You only need to add it to the document that contains the top level iframes; it will apply the fix as needed to them and their descendants.

* The jsfiddle has mouse support enabled for testing purposes. On a production site, you'd want to set mouse=false.

The right answer (using Python 2.7 and later, since check_output() was introduced then) is:

py2output = subprocess.check_output(['python','py2.py','-i', 'test.txt'])

To demonstrate, here are my two programs:

py2.py:

import sys
print sys.argv

py3.py:

import subprocess
py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'])
print('py2 said:', py2output)

Running it:

$ python3 py3.py
py2 said: b"['py2.py', '-i', 'test.txt']\n"

Here's what's wrong with each of your versions:

py2output = subprocess.check_output([str('python py2.py '),'-i', 'test.txt'])

First, str('python py2.py') is exactly the same thing as 'python py2.py'—you're taking a str, and calling str to convert it to an str. This makes the code harder to read, longer, and even slower, without adding any benefit.

More seriously, python py2.py can't be a single argument, unless you're actually trying to run a program named, say, /usr/bin/python\ py2.py. Which you're not; you're trying to run, say, /usr/bin/python with first argument py2.py. So, you need to make them separate elements in the list.

Your second version fixes that, but you're missing the ' before test.txt'. This should give you a SyntaxError, probably saying EOL while scanning string literal.

Meanwhile, I'm not sure how you found documentation but couldn't find any examples with arguments. The very first example is:

>>> subprocess.check_output(["echo", "Hello World!"])
b'Hello World!\n'

That calls the "echo" command with an additional argument, "Hello World!".

Also:

-i is a positional argument for argparse, test.txt is what the -i is

I'm pretty sure -i is not a positional argument, but an optional argument. Otherwise, the second half of the sentence makes no sense.

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:

• Add a pause to the batch file so that you can see what is happening before it exits.
  1. Right click on one of the .bat files and select "edit". This will open the file in notepad.
  2. Go to the very end of the file and add a new line by pressing "enter".
  3. type pause.
  4. Save the file.
  5. Run the file again using the same method you did before.

- OR -

• Run the batch file from a static command prompt so the window does not close.
  1. In the folder where the .bat files are located, hold down the "shift" key and right click in the white space.
  2. Select "Open Command Window Here".
  3. You will now see a new command prompt. Type in the name of the batch file and press enter.

Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.

Depends on your use case but to summarise the difference:

1. ng-if will remove elements from DOM. This means that all your handlers or anything else attached to those elements will be lost. For example, if you bound a click handler to one of child elements, when ng-if evaluates to false, that element will be removed from DOM and your click handler will not work any more, even after ng-if later evaluates to true and displays the element. You will need to reattach the handler.
2. ng-show/ng-hide does not remove the elements from DOM. It uses CSS styles to hide/show elements (note: you might need to add your own classes). This way your handlers that were attached to children will not be lost.
3. ng-if creates a child scope while ng-show/ng-hide does not

Elements that are not in the DOM have less performance impact and your web app might appear to be faster when using ng-if compared to ng-show/ng-hide. In my experience, the difference is negligible. Animations are possible when using both ng-show/ng-hide and ng-if, with examples for both in the Angular documentation.

Ultimately, the question you need to answer is whether you can remove element from DOM or not?

The link posted by Jose has been updated and pylab now has a tight_layout() function that does this automatically (in matplotlib version 1.1.0).

        System.out.println(arg0.getExtendedKeyCode());
        if (arg0.getKeyCode()==10) {
            String name = textField_in.getText();
            textField_out.setText(name);
        }

    }

});
textField_in.setBounds(173, 40, 86, 20);
frame.getContentPane().add(textField_in);
textField_in.setColumns(10);

When using SQLFiddle, make sure that the separator is set to GO. Also the schema build script is executed in a different connection from the run script, so a temp table created in the one is not visible in the other. This fiddle shows that your code is valid and working in SQL 2012:

SQL Fiddle

MS SQL Server 2012 Schema Setup:

Query 1:

  ( 
    Name1 VARCHAR(100),
    Name2 VARCHAR(100)
  ) 

INSERT INTO #Names
  (Name1, Name2)
VALUES
  ('Matt', 'Matthew'),
  ('Matt', 'Marshal'),
  ('Matt', 'Mattison')

SELECT * FROM #NAMES

Results:

I have tried all methods, which are mentioned above.But no one method works for me.finally i got solution for above issue and it is working for me.

I tried this method:

In Html:

<li><a (click)= "aboutPageLoad()"  routerLinkActive="active">About</a></li>

In TS file:

aboutPageLoad() {
    this.router.navigate(['/about']);
}

TLDR: In one line the command you are looking for:

angular.element(document.body).injector().get('serviceName')

Deep dive

AngularJS uses Dependency Injection (DI) to inject services/factories into your components,directives and other services. So what you need to do to get a service is to get the injector of AngularJS first (the injector is responsible for wiring up all the dependencies and providing them to components).

To get the injector of your app you need to grab it from an element that angular is handling. For example if your app is registered on the body element you call injector = angular.element(document.body).injector()

From the retrieved injector you can then get whatever service you like with injector.get('ServiceName')

More information on that in this answer: Can't retrieve the injector from angular
And even more here: Call AngularJS from legacy code

Another useful trick to get the $scope of a particular element. Select the element with the DOM inspection tool of your developer tools and then run the following line ($0 is always the selected element):
angular.element($0).scope()

first, you need to find the toolbox that you need. There are many people developing 3rd party toolboxes for Matlab, so there isn't just one single place where you can find "the image processing toolbox". That said, a good place to start looking is the Matlab Central which is a Mathworks-run site for exchanging all kinds of Matlab-related material.

Once you find a toolbox you want, it will be in some compressed format, and its developers might have a "readme" file that details on how to install it. If it isn't the case, a generic way to attempt installation is to place the toolbox in any directory on your drive, and then add it to Matlab path, e.g., going to File -> Set Path... -> Add Folder or Add with Subfolders (I'm writing for memory but this is definitely close).

Otherwise, you can extract all .m files in your working directory, if you don't want to use downloaded toolbox in more than one project.

Try:

trunc(Months_Between(date2, date1))

I usually get it from the toString() return value. It works in differently accessed DOM elements:

var a = document.querySelector('a');

var img = document.createElement('img');

document.body.innerHTML += '<div id="newthing"></div>';
var div = document.getElementById('newthing');

Object.prototype.toString.call(a);    // "[object HTMLAnchorElement]"
Object.prototype.toString.call(img);  // "[object HTMLImageElement]"
Object.prototype.toString.call(div);  // "[object HTMLDivElement]"

Then the relevant piece:

Object.prototype.toString.call(...).split(' ')[1].slice(0, -1);

It works in Chrome, FF, Opera, Edge, IE9+ (in older IE it return "[object Object]").

The typical solution to this is to write your own function to clone an object. If you are able to provide copy constructors and copy assignement operators, this may be as far as you need to go.

class Foo
{ 
public:
  Foo();
  Foo(const Foo& rhs) { /* copy construction from rhs*/ }
  Foo& operator=(const Foo& rhs) {};
};

// ...

Foo orig;
Foo copy = orig;  // clones orig if implemented correctly

Sometimes it is beneficial to provide an explicit clone() method, especially for polymorphic classes.

class Interface
{
public:
  virtual Interface* clone() const = 0;
};

class Foo : public Interface
{
public:
  Interface* clone() const { return new Foo(*this); }
};

class Bar : public Interface
{
public:
  Interface* clone() const { return new Bar(*this); }
};


Interface* my_foo = /* somehow construct either a Foo or a Bar */;
Interface* copy = my_foo->clone();

EDIT: Since Stack has no member variables, there's nothing to do in the copy constructor or copy assignment operator to initialize Stack's members from the so-called "right hand side" (rhs). However, you still need to ensure that any base classes are given the opportunity to initialize their members.

You do this by calling the base class:

Stack(const Stack& rhs) 
: List(rhs)  // calls copy ctor of List class
{
}

Stack& operator=(const Stack& rhs) 
{
  List::operator=(rhs);
  return * this;
};

Update: In an effort to answer my own question, here is what I've been able to uncover so far. If anyone else out there has something, I'd still be interested to find out more.

For returning multiple column indices, I recommend using the pandas.Index method get_indexer, if you have unique labels:

df = pd.DataFrame({"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]})
df.columns.get_indexer(['pear', 'apple'])
# Out: array([0, 1], dtype=int64)

If you have non-unique labels in the index (columns only support unique labels) get_indexer_for. It takes the same args as get_indeder:

df = pd.DataFrame(
    {"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]}, 
    index=[0, 1, 1])
df.index.get_indexer_for([0, 1])
# Out: array([0, 1, 2], dtype=int64)

Both methods also support non-exact indexing with, f.i. for float values taking the nearest value with a tolerance. If two indices have the same distance to the specified label or are duplicates, the index with the larger index value is selected:

df = pd.DataFrame(
    {"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]},
    index=[0, .9, 1.1])
df.index.get_indexer([0, 1])
# array([ 0, -1], dtype=int64)

   //-- Populate list from database

You can always do

git fetch && git merge --ff-only origin/master

and you will either get (a) no change if you have uncommitted changes that conflict with upstream changes or (b) the same effect as stash/pull/apply: a rebase to put you on the latest changes from HEAD and your uncommitted changes left as is.

There are 2 scenario's where Bash performance is at least equal I believe:

• Scripting of command line utilities
• Scripts which take only a short time to execute; where starting the Python interpreter takes more time than the operation itself

That said, I usually don't really concern myself with performance of the scripting language itself. If performance is a real issue you don't script but program (possibly in Python).

You mention that there are date duplicates, but it appears they're quite unique down to the precision of seconds.

Can you clarify what precision of date you start considering dates duplicate - day, hour, minute?

In any case, you'll probably want to floor your datetime field. You didn't indicate which field is preferred when removing duplicates, so this query will prefer the last name in alphabetical order.

WebpackDevServer localhost from iphone

If you are using an app which is running on node. you can use webpack as a build tool and use their built in devserver

You can use webpackdevserver to start your application from a localhost server and then pass in your localhost address and port of your choice.

webpack-dev-server --host 192.168.0.89 --port 3000

then from your iPhone you can access it using

http://192.168.2.89:3000

Note :: Your laptop and iPhone should be on the same network, and you should use your localhost ip address.

For Mac how to find ip address you can refer Get local IP address in node.js

Work bench 6.3
Follow High scoring answer then use UNCOMPRESS()

(In short:
1. Go to Edit > Preferences
2. Choose SQL Editor
3. Under SQL Execution, check Treat BINARY/VARBINARY as nonbinary character string
4. Restart MySQL Workbench (you will not be prompted or informed of this requirement).)

Then

SELECT SUBSTRING(UNCOMPRESS(<COLUMN_NAME>),1,2500) FROM <Table_name>;

or

SELECT CAST(UNCOMPRESS(<COLUMN_NAME>) AS CHAR) FROM <Table_name>;

If you just put UNCOMPRESS(<COLUMN_NAME>) you can right click blob and click "Open Value in Editor".

Use a List of custom class instances. The custom class is some sort of Pair or Coordinate or whatever. Then just

List<Coordinate> = new YourFavoriteListImplHere<Coordinate>()

This approach has the advantage that it makes satisfying this requirement "perform simple math (like multiplying the pair together to return a single float, etc)" clean, because your custom class can have methods for whatever maths you need to do...

For those wondering if jQuery id selectors are slower than document.getElementById, the answer is yes, but not because of the preconception that it searches through the entire DOM looking for an element. jQuery does actually use the native method. It's actually because jQuery uses a regular expression first to separate out strings in the selector to check by, and of course running the constructor:

rquickExpr = /^(?:(<[\w\W]+>)[^>]*|#([\w-]*))$/

Whereas using a DOM element as an argument returns immediately with 'this'.

So this:

$(document.getElementById('blah')).doSomething();

Will always be faster than this:

$('#blah').doSomething();

You can also use jQuery's delay() method instead of setTimeout(). It'll give you much more readable code. Here's an example from the docs:

$( "#foo" ).slideUp( 300 ).delay( 800 ).fadeIn( 400 );

The only limitation (that I'm aware of) is that it doesn't give you a way to clear the timeout. If you need to do that then you're better off sticking with all the nested callbacks that setTimeout thrusts upon you.

You can use Javascript to get the viewport width and height. Then pass the values back via a hidden form input or ajax.

At its simplest

var width = $(window).width();
var height = $(window).height();

Complete method using hidden form inputs

Assuming you have: JQuery framework.

First, add these hidden form inputs to store the width and height until postback.

<asp:HiddenField ID="width" runat="server" />
<asp:HiddenField ID="height" runat="server" />

Next we want to get the window (viewport) width and height. JQuery has two methods for this, aptly named width() and height().

Add the following code to your .aspx file within the head element.

<script type="text/javascript">
$(document).ready(function() {

    $("#width").val() = $(window).width();
    $("#height").val() = $(window).height();    

});
</script>

Result

This will result in the width and height of the browser window being available on postback. Just access the hidden form inputs like this:

var TheBrowserWidth = width.Value;
var TheBrowserHeight = height.Value;

This method provides the height and width upon postback, but not on the intial page load.

Note on UpdatePanels: If you are posting back via UpdatePanels, I believe the hidden inputs need to be within the UpdatePanel.

Alternatively you can post back the values via an ajax call. This is useful if you want to react to window resizing.

Update for jquery 3.1.1

I had to change the JavaScript to:

$("#width").val($(window).width());
$("#height").val($(window).height());

Go to [Tools, Options], section "Web Forms Designer" and enable the option "Enable Web Forms Designer". That should give you the Design and Split option again.

Arrays are not very dynamic in VBScript. You'll have to use the ReDim Preserve statement to grow the existing array so it can accommodate an extra item:

ReDim Preserve yourArray(UBound(yourArray) + 1)
yourArray(UBound(yourArray)) = "Watermelons"

Maybe your VMnet8 ip is not in the same network segment, e.g., my vm ip is 192.168.71.105, I can ping my windows in vm, but can't ping vm in windows, so this time you may check if vmnet8 is configured right. IP: 192.168.71.1

As per this link:

if (typeof jQuery == 'undefined') {
    // jQuery IS NOT loaded, do stuff here.
}

there are a few more in comments of the link as well like,

if (typeof jQuery == 'function') {...}

//or

if (typeof $== 'function') {...}

// or

if (jQuery) {
    alert("jquery is loaded");
} else {
    alert("Not loaded");
}

Hope this covers most of the good ways to get this thing done!!

Take an array containing months name.

String[] str = {"January",      
   "February",
   "March",        
   "April",        
   "May",          
   "June",         
   "July",         
   "August",       
   "September",    
   "October",      
   "November",     
   "December"};

Then where you wanna take month use like follow:

if(i<str.length)
    monthString = str[i-1];
else
    monthString = "Invalid month";

I tried many fixes, but what worked for me was to delete a missing target listed in the build tab of the build scheme. You can get to it by opening the edit window of the current scheme.

Edit: My UI testing target was not working as well, and the solution I found was to delete it and generate it again.

This may work

CREATE USER 'user'@'localhost' IDENTIFIED BY 'pwd';

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

@Alex Martelli's answer is great! But it work only for one element at time (WHERE name = 'Joan') If you take out the WHERE clause, the query will return all the root rows together...

I changed a little bit for my situation, so it can show the entire tree for a table.

table definition:

CREATE TABLE [dbo].[mar_categories] ( 
    [category]  int IDENTITY(1,1) NOT NULL,
    [name]      varchar(50) NOT NULL,
    [level]     int NOT NULL,
    [action]    int NOT NULL,
    [parent]    int NULL,
    CONSTRAINT [XPK_mar_categories] PRIMARY KEY([category])
)

(level is literally the level of a category 0: root, 1: first level after root, ...)

and the query:

WITH n(category, name, level, parent, concatenador) AS 
(
    SELECT category, name, level, parent, '('+CONVERT(VARCHAR (MAX), category)+' - '+CONVERT(VARCHAR (MAX), level)+')' as concatenador
    FROM mar_categories
    WHERE parent is null
        UNION ALL
    SELECT m.category, m.name, m.level, m.parent, n.concatenador+' * ('+CONVERT (VARCHAR (MAX), case when ISNULL(m.parent, 0) = 0 then 0 else m.category END)+' - '+CONVERT(VARCHAR (MAX), m.level)+')' as concatenador
    FROM mar_categories as m, n
    WHERE n.category = m.parent
)
SELECT distinct * FROM n ORDER BY concatenador asc

(You don't need to concatenate the level field, I did just to make more readable)

the answer for this query should be something like:

I hope it helps someone!

now, I'm wondering how to do this on MySQL... ^^

Late to the party, but the top voted answers all seemed like hacks to me.

All I did was remove the following from my app.config in the test project. Worked.

    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="mssqllocaldb" />

The answers to this question, while they are correct, are very unnecessarily complicated. It doesn't take that much code for text to show up in the header/footer. Here is a simple example of adding text to the header/footer.

The current version of iTextSharp works by implementing a callback class which is defined by the IPdfPageEvent interface. From what I understand, it's not a good idea to add things during the OnStartPage method, so instead I will be using the OnEndPage page method. The events are triggered depending on what is happening to the PdfWriter

First, create a class which implements IPdfPageEvent. In the:

public void OnEndPage(PdfWriter writer, Document document)

function, obtain the PdfContentByte object by calling

PdfContentByte cb = writer.DirectContent;

Now you can add text very easily:

ColumnText ct = new ColumnText(cb);

cb.BeginText();
cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
//Note, (0,0) in this case is at the bottom of the document
cb.SetTextMatrix(document.LeftMargin, document.BottomMargin); 
cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
cb.EndText();

So the full for the OnEndPage function will be:

public void OnEndPage(PdfWriter writer, Document document)
{
    PdfContentByte cb = writer.DirectContent;
    ColumnText ct = new ColumnText(cb);

    cb.BeginText();
    cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
    cb.SetTextMatrix(document.LeftMargin, document.BottomMargin);
    cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
    cb.EndText();

}

This will show up at the bottom of your document. One last thing. Don't forget to assign the IPdfPageEvent like this:

writter.PageEvent = new PDFEvents();

To the PdfWriter writter object

For the header it is very similar. Just flip the SetTextMatrix y coordinate:

cb.SetTextMatrix(document.LeftMargin, document.PageSize.Height - document.TopMargin);

One obvious and probably not efficient way is

verts = [0 for x in range(1000)]

Note that this can be extended to 2-dimension easily. For example, to get a 10x100 "array" you can do

verts = [[0 for x in range(100)] for y in range(10)]

var urlAction = 'whatever.php';
var data = {param1:'value1'};

var $form = $('<form target="_blank" method="POST" action="' + urlAction + '">');
$.each(data, function(k,v){
    $form.append('<input type="hidden" name="' + k + '" value="' + v + '">');
});
$form.submit();

The logic of encoding Unicode in UTF-8 is basically:

• Up to 4 bytes per character can be used. The fewest number of bytes possible is used.
• Characters up to U+007F are encoded with a single byte.
• For multibyte sequences, the number of leading 1 bits in the first byte gives the number of bytes for the character. The rest of the bits of the first byte can be used to encode bits of the character.
• The continuation bytes begin with 10, and the other 6 bits encode bits of the character.

Here's a function I wrote a while back for encoding a JavaScript UTF-16 string in UTF-8:

function toUTF8Array(str) {
    var utf8 = [];
    for (var i=0; i < str.length; i++) {
        var charcode = str.charCodeAt(i);
        if (charcode < 0x80) utf8.push(charcode);
        else if (charcode < 0x800) {
            utf8.push(0xc0 | (charcode >> 6), 
                      0x80 | (charcode & 0x3f));
        }
        else if (charcode < 0xd800 || charcode >= 0xe000) {
            utf8.push(0xe0 | (charcode >> 12), 
                      0x80 | ((charcode>>6) & 0x3f), 
                      0x80 | (charcode & 0x3f));
        }
        // surrogate pair
        else {
            i++;
            // UTF-16 encodes 0x10000-0x10FFFF by
            // subtracting 0x10000 and splitting the
            // 20 bits of 0x0-0xFFFFF into two halves
            charcode = 0x10000 + (((charcode & 0x3ff)<<10)
                      | (str.charCodeAt(i) & 0x3ff));
            utf8.push(0xf0 | (charcode >>18), 
                      0x80 | ((charcode>>12) & 0x3f), 
                      0x80 | ((charcode>>6) & 0x3f), 
                      0x80 | (charcode & 0x3f));
        }
    }
    return utf8;
}

Always keep in mind when you want to overcome this error, the default value of indexing and range starts from 0, so if total items is 100 then l[99] and range(99) will give you access up to the last element.

whenever you get this type of error please cross check with items that comes between/middle in range, and insure that their index is not last if you get output then you have made perfect error that mentioned above.

Try using the COLUMN command with the FORMAT option for that:

COLUMN COLUMN_NAME FORMAT 99.99
SELECT COLUMN_NAME FROM ....

It was almost correct just change your last line like:

String stopEnd = stop.substring(0, stop.length() - 1); //replace stopName with stop.

OR

you can replace your last two lines;

String stopEnd =   stopName.substring(0, stopName.length() - 2);

Dictionary.Add(key, value) and Dictionary[key] = value have different purposes:

• Use the Add method to add new key/value pair, existing keys will not be replaced (an ArgumentException is thrown).
• Use the indexer if you don't care whether the key already exists in the dictionary, in other words: add the key/value pair if the the key is not in the dictionary or replace the value for the specified key if the key is already in the dictionary.

Usually, when you create applications using C# and the .NET framework, you will not use INI files. It is more common to store settings in an XML-based configuration file or in the registry. However, if your software shares settings with a legacy application it may be easier to use its configuration file, rather than duplicating the information elsewhere.

The .NET framework does not support the use of INI files directly. However, you can use Windows API functions with Platform Invocation Services (P/Invoke) to write to and read from the files. In this link we create a class that represents INI files and uses Windows API functions to manipulate them. Please go through the following link.

The Scelbi-Byte Primer

I pored over the source code listings in this book many times until, one day, I suddenly grokked 8080 assembly language programming.

you would have to write down some method to create a temporary array and then copy it like

public String[] increaseArray(String[] theArray, int increaseBy)  
{  
    int i = theArray.length;  
    int n = ++i;  
    String[] newArray = new String[n];  
    for(int cnt=0;cnt<theArray.length;cnt++)
    {  
        newArray[cnt] = theArray[cnt];  
    }  
    return newArray;  
}  

or The ArrayList would be helpful to resolve your problem.

I have solved this if you are using array called for 2 tables. Example you have, $tableA['yellow'] and $tableA['blue'] . You are getting these 2 values and you want to add another element inside them to separate them by their type.

foreach ($tableA['yellow'] as $value) {
    $value->type = 'YELLOW';  //you are adding new element named 'type'
}

foreach ($tableA['blue'] as $value) {
    $value->type = 'BLUE';  //you are adding new element named 'type'
}

So, both of the tables value will have new element called type.

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

In my case, it was Blend SDK missed out on TeamCity machine. This caused the error due incorrect way of assembly resolving then.

For Windows Service, you need to run tomcat9w.exe (or 6w/7w/8w) depending on your version of tomcat. First, make sure tomcat is stopped. Then double click on tomcat9w.exe. Navigate to the Java tab. If you know you have 64 bit Windows with 64 bit Java and 64 bit Tomcat, then feel free to set the memory higher than 512. You'll need to do some task manager monitoring to determine how high to set it. For most apps developed in 2019... I'd recommend an initial memory pool of 1024, and the maximum memory pool of 2048. Of course if your computer has tons of RAM... feel free to go as high as you want. Also, see this answer: How to increase Maximum Memory Pool Size? Apache Tomcat 9

Late answer, but currently the accepted one is at least suboptimal.

Using quotes is ALWAYS better than using any other characters to enclose %1.
Because when %1 contains spaces or special characters like &, the IF [%1] == simply stops with a syntax error.

But for the case that %1 contains quotes, like in myBatch.bat "my file.txt", a simple IF "%1" == "" would fail.

But as you can't know if quotes are used or not, there is the syntax %~1, this removes enclosing quotes when necessary.

Therefore, the code should look like

set "file1=%~1"
IF "%~1"=="" set "file1=default file"

type "%file1%"   --- always enclose your variables in quotes

If you have to handle stranger and nastier arguments like myBatch.bat "This & will "^&crash
Then take a look at SO:How to receive even the strangest command line parameters?

If you use native sql, you can refer to my code, otherwise just ignore my answer.

SELECT * FROM table WHERE tags LIKE "%banana%";

from sqlalchemy import text

bar_tags = "banana"

# '%' attention to spaces
query_sql = """SELECT * FROM table WHERE tags LIKE '%' :bar_tags '%'"""

# db is sqlalchemy session object
tags_res_list = db.execute(text(query_sql), {"bar_tags": bar_tags}).fetchall()

You can also use the latest keyword to install the most recent version available:

  "dependencies": {
    "fontawesome": "latest"
  }

for API Level 11 or above:

case TelephonyManager.PHONE_TYPE_SIP: 
return "SIP";

TelephonyManager tm= (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
textDeviceID.setText(getDeviceID(tm));

Try the following

Dictionary<int, DateTime> existingItems = 
    (from ObjType ot in TableObj).ToDictionary(x => x.Key);

Or the fully fledged type inferenced version

var existingItems = TableObj.ToDictionary(x => x.Key);

The second one is fastest. Using strlen will be close if the string is indeed empty, but strlen will always iterate through every character of the string, so if it is not empty, it will do much more work than you need it to.

As James mentioned, the third option wipes the string out before checking, so the check will always succeed but it will be meaningless.

I haven't done this, so I'm just going to point at the right answer.

C has provisions for functions that take unspecified numbers of operands, using the <stdarg.h> header. You can define your function as void log_out(const char *fmt, ...);, and get the va_list inside the function. Then you can allocate memory and call vsprintf() with the allocated memory, format, and va_list.

Alternately, you could use this to write a function analogous to sprintf() that would allocate memory and return the formatted string, generating it more or less as above. It would be a memory leak, but if you're just logging out it may not matter.

The following code can be used:

DWORD FindProcessId(const std::wstring& processName)
{
    PROCESSENTRY32 processInfo;
    processInfo.dwSize = sizeof(processInfo);

    HANDLE processesSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
    if (processesSnapshot == INVALID_HANDLE_VALUE) {
        return 0;
    }

    Process32First(processesSnapshot, &processInfo);
    if (!processName.compare(processInfo.szExeFile))
    {
        CloseHandle(processesSnapshot);
        return processInfo.th32ProcessID;
    }

    while (Process32Next(processesSnapshot, &processInfo))
    {
        if (!processName.compare(processInfo.szExeFile))
        {
            CloseHandle(processesSnapshot);
            return processInfo.th32ProcessID;
        }
    }

    CloseHandle(processesSnapshot);
    return 0;
}

Usage:

auto processId = FindProcessId(L"blabla.exe");

Getting a handle should be obvious, just call OpenProcess() or similar on it.

I wanted to update or reset a value if it didn't quite validate, and ran into this problem.

The easy answer, ModelState.Remove, is.. problematic.. because if you are using helpers you don't really know the name (unless you stick by the naming convention). Unless perhaps you create a function that both your custom helper and your controller can use to get a name.

This feature should have been implemented as an option on the helper, where by default is does not do this, but if you wanted the unaccepted input to redisplay you could just say so.

But at least I understand the issue now ;).

Declare @MyInt int
Set @MyInt = ( Select Count(*) From MyTable )

If @MyInt > 0
Begin
    Print 'There''s something in the table'
End

I'm not sure if this is your issue, but you have to esacpe the single quote in the print statement with a second single quote. While you can use SELECT to populate the variable, using SET as you have done here is just fine and clearer IMO. In addition, you can be guaranteed that Count(*) will never return a negative value so you need only check whether it is greater than zero.

Another option is to use the cor.test function, instead of lm:

> x <- c(44.4, 45.9, 41.9, 53.3, 44.7, 44.1, 50.7, 45.2, 60.1)
> y <- c( 2.6,  3.1,  2.5,  5.0,  3.6,  4.0,  5.2,  2.8,  3.8)

> mycor = cor.test(x,y)
> mylm = lm(x~y)

# r and rsquared:
> cor.test(x,y)$estimate ** 2
      cor 
0.3262484 
> summary(lm(x~y))$r.squared
[1] 0.3262484

# P.value 

> lmp(lm(x~y))  # Using the lmp function defined in Chase's answer
[1] 0.1081731
> cor.test(x,y)$p.value
[1] 0.1081731

It's not an array, it's an object of type stdClass.

You can access it like this:

echo $oResult->context;

I was able to delete my Provisioning Profile from XCode 6 by using the Member Center online. I then just did a refresh/Sync in XCode 6 and it disappeared.

In the Apple Developer Member Center I had to do two things to make it happen:

• Under under Identifiers -> AP IDs I had to first delete the old AP ID still using the old Provisioning Profile that I wanted to delete.
  • This step was crucial for me. If I just deleted the Provisioning Profile alone without the APP ID still using it, the Profile re-appeared in XCode after a Sync.
• Under Provisioning Profiles I then deleted the unwanted provisioning profile.

In XCode:

• Under Preferences > Accounts, clicking on my apple ID and View Details... I Sync'd my online provisioning profiles.
• The Provisioning Profile removed itself from the list.

If you want to imitate click on the DOM element like this:

<a (click)="showLogin($event)">login</a>

and have something like this on the page:

<li ngbDropdown>
    <a ngbDropdownToggle id="login-menu">
        ...
    </a>
 </li>

your function in component.ts should be like this:

showLogin(event) {
   event.stopPropagation();
   document.getElementById('login-menu').click();
}

if you are working in the java world - intelliJ idea has also extensive xml support, including xsd generation and samle xml from xsd generation, and with plugins you can get xslt debuggers. - especially nice if you plan to use tools such as jaxb afterwards.

Here is a good example -

ul li{
    list-style-type: disc;
    list-style-position: inside;
    padding: 10px 0 10px 20px;
    text-indent: -1em;
}
