I frequently stumble upon this issue while bulk moving files to new subdirectories. Ideally, I want to do this:

mv * newdir/  

Most of the answers in this thread propose to mkdir and then mv, but this results in:

mkdir newdir && mv * newdir 
mv: cannot move 'newdir/' to a subdirectory of itself

The problem I face is slightly different in that I want to blanket move everything, and, if I create the new directory before moving then it also tries to move the new directory to itself. So, I work around this by using the parent directory:

mkdir ../newdir && mv * ../newdir && mv ../newdir .

Caveats: Does not work in the root folder (/).

To create multiple sub-folders

mkdir -p parentfolder/{subfolder1,subfolder2,subfolder3}

mkdir foo works even if the directory exists. To make it work only if the directory named "foo" does not exist, try using the -p flag.

Example:

mkdir -p foo

This will create the directory named "foo" only if it does not exist. :)

Take a look at the bash source code here, and specifically look in examples/loadables/mkdir.c especially lines 136-210. If you don't want to do that, here's some of the source that deals with this (taken straight from the tar.gz that I've linked):

/* Make all the directories leading up to PATH, then create PATH.  Note that
   this changes the process's umask; make sure that all paths leading to a
   return reset it to ORIGINAL_UMASK */

static int
make_path (path, nmode, parent_mode)
     char *path;
     int nmode, parent_mode;
{
  int oumask;
  struct stat sb;
  char *p, *npath;

  if (stat (path, &sb) == 0)
  {
      if (S_ISDIR (sb.st_mode) == 0)
      {
          builtin_error ("`%s': file exists but is not a directory", path);
          return 1;
      }

      if (chmod (path, nmode))
      {
          builtin_error ("%s: %s", path, strerror (errno));
          return 1;
      }

      return 0;
  }

  oumask = umask (0);
  npath = savestring (path);    /* So we can write to it. */

  /* Check whether or not we need to do anything with intermediate dirs. */

  /* Skip leading slashes. */
  p = npath;
  while (*p == '/')
    p++;

  while (p = strchr (p, '/'))
  {
      *p = '\0';
      if (stat (npath, &sb) != 0)
      {
          if (mkdir (npath, parent_mode))
          {
              builtin_error ("cannot create directory `%s': %s", npath, strerror (errno));
              umask (original_umask);
              free (npath);
              return 1;
          }
      }
      else if (S_ISDIR (sb.st_mode) == 0)
      {
          builtin_error ("`%s': file exists but is not a directory", npath);
          umask (original_umask);
          free (npath);
          return 1;
      }

      *p++ = '/';   /* restore slash */
      while (*p == '/')
          p++;
  }

  /* Create the final directory component. */
  if (stat (npath, &sb) && mkdir (npath, nmode))
  {
      builtin_error ("cannot create directory `%s': %s", npath, strerror (errno));
      umask (original_umask);
      free (npath);
      return 1;
  }

  umask (original_umask);
  free (npath);
  return 0;
}

You can probably get away with a less general implementation.

If the issue is to create all the necessary parent directories, you could consider using os.MkDirAll()

MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error.

The path_test.go is a good illustration on how to use it:

func TestMkdirAll(t *testing.T) {
    tmpDir := TempDir()
    path := tmpDir + "/_TestMkdirAll_/dir/./dir2"
    err := MkdirAll(path, 0777)
    if err != nil {
    t.Fatalf("MkdirAll %q: %s", path, err)
    }
    defer RemoveAll(tmpDir + "/_TestMkdirAll_")
...
}

(Make sure to specify a sensible permission value, as mentioned in this answer)

According to mkdir's man page...

mkdir -m 777 dirname

I've had success with the following personally, but my function should probably be called something like 'ensure this directory exists':

def mkdirRecursive(dirpath):
    import os
    if os.path.isdir(dirpath): return

    h,t = os.path.split(dirpath) # head/tail
    if not os.path.isdir(h):
        mkdirRecursive(h)

    os.mkdir(join(h,t))
# end mkdirRecursive

You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:

newpath = r'C:\Program Files\arbitrary' 
if not os.path.exists(newpath):
    os.makedirs(newpath)

If you're trying to make an installer: Windows Installer does a lot of work for you.

Chrome DevTools, Safari Inspector and Firebug support getEventListeners(node).

Ways of inline styling:

<View style={[styles.red, {fontSize: 25}]}>
  <Text>Hello World</Text>
</View>

<View style={[styles.red, styles.blue]}>
  <Text>Hello World</Text>
</View>

  <View style={{fontSize:10,marginTop:10}}>
  <Text>Hello World</Text>
</View>

To get the value of a pointer, just de-reference the pointer.

int *ptr;
int value;
*ptr = 9;

value = *ptr;

value is now 9.

I suggest you read more about pointers, this is their base functionality.

Without rooting: If you can't root your phone, use the run-as <package> command to be able to access data of your application.

Example:

$ adb exec-out run-as com.yourcompany.app ls -R /data/data/com.yourcompany.app/

exec-out executes the command without starting a shell and mangling the output.

Because of historical reasons going back to the very first version of C, functions are assumed to have an implicit definition of int function(int arg1, int arg2, int arg3, etc).

Edit: no, I was wrong about int for the arguments. Instead it passes whatever type the argument is. So it could be an int or a double or a char*. Without a prototype the compiler will pass whatever size the argument is and the function being called had better use the correct argument type to receive it.

For more details look up K&R C.

function printCrossword(printContainer) {
    var DocumentContainer = getElement(printContainer);
    var WindowObject = window.open('', "PrintWindow", "width=5,height=5,top=200,left=200,toolbars=no,scrollbars=no,status=no,resizable=no");
    WindowObject.document.writeln(DocumentContainer.innerHTML);
    WindowObject.document.close();
    WindowObject.focus();
    WindowObject.print();
    WindowObject.close();
}

It allows you to queue up animations... for example, instead of this

$('#my-element').animate( { opacity: 0.2, width: '100px' }, 2000);

Which fades the element and makes the width 100 px at the same time. Using the queue allows you to stage the animations. So one finishes after the other.

$("#show").click(function () {
    var n = $("div").queue("fx");
    $("span").text("Queue length is: " + n.length);
});

function runIt() {
    $("div").show("slow");
    $("div").animate({left:'+=200'},2000);
    $("div").slideToggle(1000);
    $("div").slideToggle("fast");
    $("div").animate({left:'-=200'},1500);
    $("div").hide("slow");
    $("div").show(1200);
    $("div").slideUp("normal", runIt);
}
runIt();

Example from http://docs.jquery.com/Effects/queue

As everybody already have said, you use this(…), which is called an explicit constructor invocation.

However, keep in mind that within such an explicit constructor invocation statement you may not refer to

• any instance variables or
• any instance methods or
• any inner classes declared in this class or any superclass, or
• this or
• super.

As stated in JLS (§8.8.7.1).

With the help of Tim C's answer, I was able to create an extension on UIButton using Swift that allows you to specify the image frame by using the .setImage() function with an extra frame parameter

extension UIButton{

    func setImage(image: UIImage?, inFrame frame: CGRect?, forState state: UIControlState){
        self.setImage(image, forState: state)

        if let frame = frame{
            self.imageEdgeInsets = UIEdgeInsets(
                top: frame.minY - self.frame.minY,
                left: frame.minX - self.frame.minX,
                bottom: self.frame.maxY - frame.maxY,
                right: self.frame.maxX - frame.maxX
            )
        }
    }

}

Using this, if you wanted to set the frame of a UIButton to CGRectMake(0, 0, 64, 64), and set the image of it to myImage with a frame of CGRectMake(8, 8, 48, 48), you could use

let button: UIButton = UIButton(frame: CGRectMake(0, 0, 64, 64))
button.setImage(
    myImage,
    inFrame: CGRectMake(8, 8, 48, 48),
    forState: UIControlState.Normal
)

A DateTime in C# is a value type, not a reference type, and therefore cannot be null. It can however be the constant DateTime.MinValue which is outside the range of Sql Servers DATETIME data type.

Value types are guaranteed to always have a (default) value (of zero) without always needing to be explicitly set (in this case DateTime.MinValue).

Conclusion is you probably have an unset DateTime value that you are trying to pass to the database.

DateTime.MinValue = 1/1/0001 12:00:00 AM
DateTime.MaxValue = 23:59:59.9999999, December 31, 9999, 
                    exactly one 100-nanosecond tick 
                    before 00:00:00, January 1, 10000

MSDN: DateTime.MinValue

Regarding Sql Server

datetime
Date and time data from January 1, 1753 through December 31, 9999, to an accuracy of one three-hundredth of a second (equivalent to 3.33 milliseconds or 0.00333 seconds). Values are rounded to increments of .000, .003, or .007 seconds

smalldatetime
Date and time data from January 1, 1900, through June 6, 2079, with accuracy to the minute. smalldatetime values with 29.998 seconds or lower are rounded down to the nearest minute; values with 29.999 seconds or higher are rounded up to the nearest minute.

MSDN: Sql Server DateTime and SmallDateTime

Lastly, if you find yourself passing a C# DateTime as a string to sql, you need to format it as follows to retain maximum precision and to prevent sql server from throwing a similar error.

string sqlTimeAsString = myDateTime.ToString("yyyy-MM-ddTHH:mm:ss.fff");

Update (8 years later)

Consider using the sql DateTime2 datatype which aligns better with the .net DateTime with date range 0001-01-01 through 9999-12-31 and time range 00:00:00 through 23:59:59.9999999

string dateTime2String = myDateTime.ToString("yyyy-MM-ddTHH:mm:ss.fffffff");

It means you should use logging framework like logback or log4j and instead of printing exceptions directly:

e.printStackTrace();

you should log them using this frameworks' API:

log.error("Ops!", e);

Logging frameworks give you a lot of flexibility, e.g. you can choose whether you want to log to console or file - or maybe skip some messages if you find them no longer relevant in some environment.

This is an old question but you can also use express-validator package to check request params

express-validator version 4 (latest):

validator = require('express-validator/check');

app.get('/show/:id', [

    validator.param('id').isMongoId().trim()

], function(req, res) {

    // validation result
    var errors = validator.validationResult(req);

    // check if there are errors
    if ( !errors.isEmpty() ) {
        return res.send('404');
    }

    // else 
    model.findById(req.params.id, function(err, doc) { 
        return res.send(doc);
    });

});

express-validator version 3:

var expressValidator = require('express-validator');
app.use(expressValidator(middlewareOptions));

app.get('/show/:id', function(req, res, next) {

    req.checkParams('id').isMongoId();

    // validation result
    req.getValidationResult().then(function(result) {

        // check if there are errors
        if ( !result.isEmpty() ) {
            return res.send('404');
        }

        // else
        model.findById(req.params.id, function(err, doc) {
            return res.send(doc);
        });

    });

});

@Entity
@NamedQuery(name = "Customer.listUniqueNames", 
            query = "SELECT DISTINCT c.name FROM Customer c")
public class Customer {
        ...

        private String name;

        public static List<String> listUniqueNames() {
             return = getEntityManager().createNamedQuery(
                   "Customer.listUniqueNames", String.class)
                   .getResultList();
        }
}

Understanding how computer time works is very important. With that said I agree that if an API is created to help you process computer time like real time then it should work in such a way that allows you to treat it like real time. For the most part this is the case but there are some major oversights which do need attention.

Anyway I digress!! If you have your UTC offset (better to work in UTC than GMT offsets) you can calculate the time in milliseconds and add that to your timestamp. Note that an SQL Timestamp may vary from a Java timestamp as the way the elapse from the epoch is calculated is not always the same - dependant on database technologies and also operating systems.

I would advise you to use System.currentTimeMillis() as your time stamps as these can be processed more consistently in java without worrying about converting SQL Timestamps to java Date objects etc.

To calculate your offset you can try something like this:

Long gmtTime =1317951113613L; // 2.32pm NZDT
Long timezoneAlteredTime = 0L;

if (offset != 0L) {
    int multiplier = (offset*60)*(60*1000);
    timezoneAlteredTime = gmtTime + multiplier;
} else {
    timezoneAlteredTime = gmtTime;
}

Calendar calendar = new GregorianCalendar();
calendar.setTimeInMillis(timezoneAlteredTime);

DateFormat formatter = new SimpleDateFormat("dd MMM yyyy HH:mm:ss z");

formatter.setCalendar(calendar);
formatter.setTimeZone(TimeZone.getTimeZone(timeZone));

String newZealandTime = formatter.format(calendar.getTime());

I hope this is helpful!

You should use partial views. I use the following approach:

Use a view model so you're not passing your domain models to your views:

public class EditPersonViewModel
{
    public int Id { get; set; }   // this is only used to retrieve record from Db
    public string Name { get; set; }
    public string Age { get; set; }
}

In your PersonController:

[HttpGet] // this action result returns the partial containing the modal
public ActionResult EditPerson(int id)
{  
    var viewModel = new EditPersonViewModel();
    viewModel.Id = id;
    return PartialView("_EditPersonPartial", viewModel);
}

[HttpPost] // this action takes the viewModel from the modal
public ActionResult EditPerson(EditPersonViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var toUpdate = personRepo.Find(viewModel.Id);
        toUpdate.Name = viewModel.Name;
        toUpdate.Age = viewModel.Age;
        personRepo.InsertOrUpdate(toUpdate);
        personRepo.Save();
        return View("Index");
    }
}

Next create a partial view called _EditPersonPartial. This contains the modal header, body and footer. It also contains the Ajax form. It's strongly typed and takes in our view model.

@model Namespace.ViewModels.EditPersonViewModel
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Edit group member</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
                    new AjaxOptions
                    {
                        InsertionMode = InsertionMode.Replace,
                        HttpMethod = "POST",
                        UpdateTargetId = "list-of-people"
                    }))
{
    @Html.ValidationSummary()
    @Html.AntiForgeryToken()
    <div class="modal-body">
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Name)
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Age)
    </div>
    <div class="modal-footer">
        <button class="btn btn-inverse" type="submit">Save</button>
    </div>
}

Now somewhere in your application, say another partial _peoplePartial.cshtml etc:

<div>
   @foreach(var person in Model.People)
    {
        <button class="btn btn-primary edit-person" data-id="@person.PersonId">Edit</button>
    }
</div>
// this is the modal definition
<div class="modal hide fade in" id="edit-person">
    <div id="edit-person-container"></div>
</div>

    <script type="text/javascript">
    $(document).ready(function () {
        $('.edit-person').click(function () {
            var url = "/Person/EditPerson"; // the url to the controller
            var id = $(this).attr('data-id'); // the id that's given to each button in the list
            $.get(url + '/' + id, function (data) {
                $('#edit-person-container').html(data);
                $('#edit-person').modal('show');
            });
        });
     });
   </script>

I'm running JMeter 2.8 (Windows 7) and received a message similar to that in the original post:

C:\>jmeter
Error: Unable to access jarfile C:\local\software\jMeter\apache-jmeter-2.8\binApacheJMeter.jar
errorlevel=1
Press any key to continue . . .

I'd created a Windows environment variable JMETER_BIN and set it to the JMeter path which I could see contained ApacheJMeter.jar (so it wasn't a question that the jar was missing).

I should have noticed at the time this portion of the error: "binApacheJMeter.jar"

When I went to the jmeter.bat file to troubleshoot, I noticed this line:

%JM_START% %JM_LAUNCH% %ARGS% %JVM_ARGS% -jar "%JMETER_BIN%ApacheJMeter.jar" %JMETER_CMD_LINE_ARGS%

and that caused me to revisit the "binApacheJMeter.jar" portion of the error.

What was happening was that the batch file was requiring a trailing slash on the end of the path in the JMETER_BIN environment variable to correctly specify the location of the .jar.

Once I corrected my environment variable, adding the trailing slash, all was wonderful.

YMMV, but this worked for me.

I have an example I would like to share

$File = "C:\Foo.txt"
#retrieves the Systems current Date and Time in a DateTime Format
$today = Get-Date
#subtracts 12 hours from the date to ensure the file has been written to recently
$today = $today.AddHours(-12)
#gets the last time the $file was written in a DateTime Format
$lastWriteTime = (Get-Item $File).LastWriteTime

#If $File doesn't exist we will loop indefinetely until it does exist.
# also loops until the $File that exists was written to in the last twelve hours
while((!(Test-Path $File)) -or ($lastWriteTime -lt $today))
{
    #if a file exists then the write time is wrong so update it
    if (Test-Path $File)
    {
        $lastWriteTime = (Get-Item $File).LastWriteTime
    }
    #Sleep for 5 minutes
    $time = Get-Date
    Write-Host "Sleep" $time
    Start-Sleep -s 300;
}

While sizeof works for this specific type of string:

char str[] = "content";
int charcount = sizeof str - 1; // -1 to exclude terminating '\0'

It does not work if str is pointer (sizeof returns size of pointer, usually 4 or 8) or array with specified length (sizeof will return the byte count matching specified length, which for char type are same).

Just use strlen().

    private func createButton {
        let sayButtonT = UIButton(type: .custom)

    }

Please check: http://man7.org/linux/man-pages/man5/proc.5.html

address           perms offset  dev   inode       pathname
00400000-00452000 r-xp 00000000 08:02 173521      /usr/bin/dbus-daemon

The address field is the address space in the process that the mapping occupies.

The perms field is a set of permissions:

 r = read
 w = write
 x = execute
 s = shared
 p = private (copy on write)

The offset field is the offset into the file/whatever;

dev is the device (major:minor);

inode is the inode on that device.0 indicates that no inode is associated with the memoryregion, as would be the case with BSS (uninitialized data).

The pathname field will usually be the file that is backing the mapping. For ELF files, you can easily coordinate with the offset field by looking at the Offset field in the ELF program headers (readelf -l).

Under Linux 2.0, there is no field giving pathname.

Goto the Src folder of your Android project, and open the Java file.

Change the package OldName.android.widget to newName.android.widget.

It gives you an error like this

The declared package "newName.android.widget" does not match the expected package "OLDName.android.widget.

To fix this problem, select Move filename.Java to Newname.android.widget and delete the old package folder.

Next step: Go to AndroidManifest.xml and change package="OldName.android.widget" to package="newName.android.widget".

Like others have mentioned, a functor is an object that acts like a function, i.e. it overloads the function call operator.

Functors are commonly used in STL algorithms. They are useful because they can hold state before and between function calls, like a closure in functional languages. For example, you could define a MultiplyBy functor that multiplies its argument by a specified amount:

class MultiplyBy {
private:
    int factor;

public:
    MultiplyBy(int x) : factor(x) {
    }

    int operator () (int other) const {
        return factor * other;
    }
};

Then you could pass a MultiplyBy object to an algorithm like std::transform:

int array[5] = {1, 2, 3, 4, 5};
std::transform(array, array + 5, array, MultiplyBy(3));
// Now, array is {3, 6, 9, 12, 15}

Another advantage of a functor over a pointer to a function is that the call can be inlined in more cases. If you passed a function pointer to transform, unless that call got inlined and the compiler knows that you always pass the same function to it, it can't inline the call through the pointer.

You update core-js with the following command:

npm install --save core-js@^3

If you read the React Docs you will find that the command is derived from when you need to upgrade React itself.

If you're in a situation like @Keith you could try:

print(a.__dict__)

It goes against what I would consider good style but if you're just trying to debug then it should do what you want.

Css workaround for forcing columns to display correctly with a 'block' tbody

This solution still requires the th widths to be calculated and set by jQuery

table.scroll tbody,
table.scroll thead { display: block; }

table.scroll tbody {
    overflow-y: auto;
    overflow-x: hidden;
    max-height: 300px;
}

table.scroll tr {
    display: flex;
}

table.scroll tr > td {
    flex-grow: 1;
    flex-basis: 0;
}

And the Jquery / Javascript

var $table = $('#the_table_element'),
    $bodyCells = $table.find('tbody tr:first').children(),
    colWidth;

$table.addClass('scroll');

// Adjust the width of thead cells when window resizes
$(window).resize(function () {

    // Get the tbody columns width array
    colWidth = $bodyCells.map(function () {
        return $(this).width();
    }).get();

    // Set the width of thead columns
    $table.find('thead tr').children().each(function (i, v) {
        $(v).width(colWidth[i]);
    });

}).resize(); // Trigger resize handler

The easy way to change version is first to check your available version using nvm ls then select version from the list nvm use version

I'd personally make use of the table.insert function:

table.insert(a,"b");

This saves you from having to iterate over the whole table therefore saving valuable resources such as memory and time.

Try this:

HTML:

<input type="submit" value="submit" name="submit" onclick="myfunction()">

jQuery:

<script type="text/javascript">
 function myfunction() 
 {
    var url = $(location).attr('href');
    $('#spn_url').html('<strong>' + url + '</strong>');
 }
</script>

function String2Stars($string='',$first=0,$last=0,$rep='*'){
  $begin  = substr($string,0,$first);
  $middle = str_repeat($rep,strlen(substr($string,$first,$last)));
  $end    = substr($string,$last);
  $stars  = $begin.$middle.$end;
  return $stars;
}

example

$string = 'abcdefghijklmnopqrstuvwxyz';
echo String2Stars($string,5,-5);   // abcde****************vwxyz

The above answer seems good. But another way of doing this is adding the auto commit option along with the db connect. This automatically commits every other operations performed in the db, avoiding the use of mentioning sql.commit() every time.

 mydb = MySQLdb.connect(host='localhost',
        user='root',
        passwd='',
        db='mydb',autocommit=true)

Kotlin

For those using Kotlin who are following the docs package conventions:

In pure Kotlin projects, the recommended directory structure is to follow the package structure with the common root package omitted (e.g. if all the code in the project is in the "org.example.kotlin" package and its subpackages, files with the "org.example.kotlin" package should be placed directly under the source root, and files in "org.example.kotlin.foo.bar" should be in the "foo/bar" subdirectory of the source root).

IntelliJ doesn't support this yet. The only thing you can do is to disable this warning, and accept that the IDE will not help you with refactorings when it comes to changing folders/files structures.

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark` 
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          FIRST";

Use pandas:

import pandas as pd
my_csv = pd.read_csv(filename)
column = my_csv.column_name
# you can also use my_csv['column_name']

Discard unneeded columns at parse time:

my_filtered_csv = pd.read_csv(filename, usecols=['col1', 'col3', 'col7'])

P.S. I'm just aggregating what other's have said in a simple manner. Actual answers are taken from here and here.

Alternative solution (you can replace createElement with a your own element)

var mvar = $('.mbox').wrapAll(document.createElement('div')).closest('div').text();
console.log(mvar);

To save yourself time and hassle in the future you can make an Int extension. Typically I create a shared code file where I put extensions, enums, and other fun stuff. Here is what the extension code looks like:

extension Int
{
    func toString() -> String
    {
        var myString = String(self)
        return myString
    }
}

Then later when you want to convert an int to a string you can just do something like:

var myNumber = 0
var myNumberAsString = myNumber.toString()

To export data to csv/excel from Kibana follow the following steps:-

1. Click on Visualize Tab & select a visualization (if created). If not created create a visualziation.

2. Click on caret symbol (^) which is present at the bottom of the visualization.

3. Then you will get an option of Export:Raw Formatted as the bottom of the page.

Please find below attached image showing Export option after clicking on caret symbol.

We had the same issue when we had a typo in the mybatis mapping file like

        ....
        #{column1Name,          jdbcType=INTEGER},
        #{column2Name,          jdbcType=VARCHAR},
        #{column3Name,      jdbcTyep=VARCHAR}  -- do you see the typo ?
        .....

So check this kind of typos as well. Unfortunately, it can not understand the typo in compile/build time, it causes an unchecked exception and booms in runtime.

You could manually set the cookie, but depending on your use case (and if you might want to add more types of persistent/session data in future) it might make more sense to use Django's sessions feature. This will let you get and set variables tied internally to the user's session cookie. Cool thing about this is that if you want to store a lot of data tied to a user's session, storing it all in cookies will add a lot of weight to HTTP requests and responses. With sessions the session cookie is all that is sent back and forth (though there is the overhead on Django's end of storing the session data to keep in mind).

Why javascript when you can use just css?

SIMPLE XML EXAMPLE:

<school>
  <firstname>John</firstname>
  <lastname>Smith</lastname>
</school>

XSD OF ABOVE XML(Explained):

<xs:element name="school">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="firstname" type="xs:string"/>
      <xs:element name="lastname" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

Here:

xs:element : Defines an element.

xs:sequence : Denotes child elements only appear in the order mentioned.

xs:complexType : Denotes it contains other elements.

xs:simpleType : Denotes they do not contain other elements.

type: string, decimal, integer, boolean, date, time,

• In simple words, xsd is another way to represent and validate XML data with the specific type.

• With the help of extra attributes, we can perform multiple operations.

• Performing any task on xsd is simpler than xml.

If all the other answers do not work for you check the config.inc.php for the following:

$cfg['Servers'][$i]['host'] = '127.0.0.1';

…and add the port of MySQL set in your XAMPP as shown below:

$cfg['Servers'][$i]['host'] = '127.0.0.1:3307';

Stop MySQL from XAMPP and restart MySQL.

Open a fresh page for http://localhost:8012/phpmyadmin/ and check.

Try this

 $.cookie('_cookieName', null, { path: '/' });

The { path: '/' } do the job for you

By Timestamp, I presume you mean java.sql.Timestamp. You will notice that this class has a constructor that accepts a long argument. You can parse this using the DateFormat class:

DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date date = dateFormat.parse("23/09/2007");
long time = date.getTime();
new Timestamp(time);

input fields can be styled as you wish. So instead of zoom, you could have

input[type="checkbox"]{
  width: 30px; /*Desired width*/
  height: 30px; /*Desired height*/
}

EDIT:

You would have to add extra rules like this:

input[type="checkbox"]{
  width: 30px; /*Desired width*/
  height: 30px; /*Desired height*/
  cursor: pointer;
  -webkit-appearance: none;
  appearance: none;
}

default value is chosen at runtime based on system configuration

Have a look at the documentation page

Default Heap Size

Unless the initial and maximum heap sizes are specified on the command line, they are calculated based on the amount of memory on the machine.

1. Client JVM Default Initial and Maximum Heap Sizes:

   The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes (MB) and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte (GB).

2. Server JVM Default Initial and Maximum Heap Sizes:

   On 32-bit JVMs, the default maximum heap size can be up to 1 GB if there is 4 GB or more of physical memory. On 64-bit JVMs, the default maximum heap size can be up to 32 GB if there is 128 GB or more of physical memory

What system configuration settings influence the default value?

You can specify the initial and maximum heap sizes using the flags -Xms (initial heap size) and -Xmx (maximum heap size). If you know how much heap your application needs to work well, you can set -Xms and -Xmx to the same value

You don't need that sort of solution for string literals, since they are concatenated at the language level, and it wouldn't work anyway because "s""1" isn't a valid preprocessor token.

[Edit: In response to the incorrect "Just for the record" comment below that unfortunately received several upvotes, I will reiterate the statement above and observe that the program fragment

#define PPCAT_NX(A, B) A ## B
PPCAT_NX("s", "1")

produces this error message from the preprocessing phase of gcc: error: pasting ""s"" and ""1"" does not give a valid preprocessing token

]

However, for general token pasting, try this:

/*
 * Concatenate preprocessor tokens A and B without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define PPCAT_NX(A, B) A ## B

/*
 * Concatenate preprocessor tokens A and B after macro-expanding them.
 */
#define PPCAT(A, B) PPCAT_NX(A, B)

Then, e.g., both PPCAT_NX(s, 1) and PPCAT(s, 1) produce the identifier s1, unless s is defined as a macro, in which case PPCAT(s, 1) produces <macro value of s>1.

Continuing on the theme are these macros:

/*
 * Turn A into a string literal without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define STRINGIZE_NX(A) #A

/*
 * Turn A into a string literal after macro-expanding it.
 */
#define STRINGIZE(A) STRINGIZE_NX(A)

Then,

#define T1 s
#define T2 1
STRINGIZE(PPCAT(T1, T2)) // produces "s1"

By contrast,

STRINGIZE(PPCAT_NX(T1, T2)) // produces "T1T2"
STRINGIZE_NX(PPCAT_NX(T1, T2)) // produces "PPCAT_NX(T1, T2)"

#define T1T2 visit the zoo
STRINGIZE(PPCAT_NX(T1, T2)) // produces "visit the zoo"
STRINGIZE_NX(PPCAT(T1, T2)) // produces "PPCAT(T1, T2)"

geonames is nice. an export tool based on geonames:

If you using Mac OS, you should install PostgreSQL from source. After installation is finished, you need to add this path using:

export PATH=/local/pgsql/bin:$PATH

or you can append the path like this:

export PATH=.../:usr/local/pgsql/bin

in your .profile file or .zshrc file.

This maybe vary by operating system.

You can follow the installation process from http://www.thegeekstuff.com/2009/04/linux-postgresql-install-and-configure-from-source/

Sure it's inefficient and many despise it, but it's one of the closest to the mentioned:

var myStringArray = ["Hello","World"];
myStringArray.forEach(function(f){
    // Do something
})

As there is no built in function for string length, you can write your own function like this one:

@echo off
setlocal
REM *** Some tests, to check the functionality ***
REM *** An emptyStr has the length 0
set "emptyString="
call :strlen result emptyString
echo %result%

REM *** This string has the length 14
set "myString=abcdef!%%^^()^!"
call :strlen result myString
echo %result%

REM *** This string has the maximum length of 8191
setlocal EnableDelayedExpansion
set "long=."
FOR /L %%n in (1 1 13) DO set "long=!long:~-4000!!long:~-4000!"
(set^ longString=!long!!long:~-191!)

call :strlen result longString
echo %result%

goto :eof

REM ********* function *****************************
:strlen <resultVar> <stringVar>
(   
    setlocal EnableDelayedExpansion
    (set^ tmp=!%~2!)
    if defined tmp (
        set "len=1"
        for %%P in (4096 2048 1024 512 256 128 64 32 16 8 4 2 1) do (
            if "!tmp:~%%P,1!" NEQ "" ( 
                set /a "len+=%%P"
                set "tmp=!tmp:~%%P!"
            )
        )
    ) ELSE (
        set len=0
    )
)
( 
    endlocal
    set "%~1=%len%"
    exit /b
)

This function needs always 13 loops, instead of a simple strlen function which needs strlen-loops.
It handles all characters.

The strange expression (set^ tmp=!%~2!) is necessary to handle ultra long strings, else it's not possible to copy them.

A simple solution:

original = [1,2,3]
cloned = original.map(x=>x)

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

OK, I landed here because I recently came across the same issue when checking the classic stack implementation. Just a reminder that this is used in the array based implementation of Stack, which is a bit faster than the linked-list one.

Code below, check the push and pop func.

public class FixedCapacityStackOfStrings
{
  private String[] s;
  private int N=0;

  public FixedCapacityStackOfStrings(int capacity)
  { s = new String[capacity];}

  public boolean isEmpty()
  { return N == 0;}

  public void push(String item)
  { s[N++] = item; }

  public String pop()
  { 
    String item = s[--N];
    s[N] = null;
    return item;
  }
}

google.com is not responding to HTTP HEAD requests, which is why you are seeing a hang for the first command.

It does respond to GET requests, which is why the third command works.

As for the second, curl just prints the headers from a standard request.

If you're looking to generate a single error message string that contains the ModelState error messages you can use SelectMany to flatten the errors into a single list:

if (!ModelState.IsValid)
{
    var message = string.Join(" | ", ModelState.Values
        .SelectMany(v => v.Errors)
        .Select(e => e.ErrorMessage));
    return new HttpStatusCodeResult(HttpStatusCode.BadRequest, message);
}

If you're on Linux and are using a VIm version 7.3.74 or higher (the version that gets installed in Ubuntu 11.10 onwards satisfies this), you can do

set clipboard=unnamedplus

which will place yanked text into the global clipboard, and allow you to paste from the global clipboard, without having to use any special registers. Unlike ldigas's solution, this will also work on non-gui versions of VIm.

I had a couple of issues with the answers here, such as when you added in the padding, the width of the content was overflowing the box and that I wanted some corner radius. I solved this using the following subclass of UILabel:

#import "MyLabel.h"

#define PADDING 8.0
#define CORNER_RADIUS 4.0

@implementation MyLabel

- (void)drawRect:(CGRect)rect {
 self.layer.masksToBounds = YES;
 self.layer.cornerRadius = CORNER_RADIUS;
 UIEdgeInsets insets = {0, PADDING, 0, PADDING};
 return [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}
- (CGSize) intrinsicContentSize {
 CGSize intrinsicSuperViewContentSize = [super intrinsicContentSize] ;
 intrinsicSuperViewContentSize.width += PADDING * 2 ;
 return intrinsicSuperViewContentSize ;
}

@end

Hope that's helpful to someone! Note that if you wanted padding on the top and bottom, you would need to change this lines:

UIEdgeInsets insets = {0, PADDING, 0, PADDING};

To this:

UIEdgeInsets insets = {PADDING, PADDING, PADDING, PADDING};

And add this line underneath the similar one for width:

intrinsicSuperViewContentSize.height += PADDING * 2 ;

<div class="row" style="padding-left:21px;">
    <ul class="nav nav-tabs" style="padding-left:40px;">
        <li class="active filter"><a href="#month" onclick="Data(this)">This Month</a></li>
        <li class="filter"><a href="#year" onclick="Data(this)">Year</a></li>
        <li class="filter"><a href="#last60" onclick="Data(this)">60 Days</a></li>
        <li class="filter"><a href="#last90" onclick="Data(this)">90 Days</a></li>
    </ul>

</div>

<script>
    function Data(element)
    {     
       element.removeClass('active');
       element.addClass('active') ;
    }
</script>

org.apache.commons.io.FileUtils.touch(yourFile) doesn't check if your file is open or not. Instead, it changes the timestamp of the file to the current time.

I used IOException and it works just fine:

try 
{
  String filePath = "C:\sheet.xlsx";
  FileWriter fw = new FileWriter(filePath );                
}
catch (IOException e)
{
    System.out.println("File is open");
}

For ASP.NET Core you'll need to spell it out:

@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.Path}{Context.Request.QueryString}")

Or you can add a using statement to your view:

@using Microsoft.AspNetCore.Http.Extensions

then

@Context.Request.GetDisplayUrl()

The _ViewImports.cshtml might be a better place for that @using

In my case it was trying to call JSON.parse() on an AJAX variable before the XHRResponse came back. EG:

var response = $.get(URL that returns a valid JSON string);
var data = JSON.parse(response.responseText);

I replaced that with an example out of the jQuery site for $.get:

<script type="text/javascript"> 
    var jqxhr = $.get( "https://jira.atlassian.com/rest/api/2/project", function() {
          alert( "success" );
        })
          .done(function() {
//insert code to assign the projects from Jira to a div.
                jqxhr = jqxhr.responseJSON;
                console.log(jqxhr);
                var div = document.getElementById("products");
                for (i = 0; i < jqxhr.length; i++) {
                    console.log(jqxhr[i].name);
                    div.innerHTML += "<b>Product: " + jqxhr[i].name + "</b><BR/>Key: " + jqxhr[i].key + "<BR/>";
                }
                console.log(div);
            alert( "second success" );
          })
          .fail(function() {
            alert( "error" );
          })
          .always(function() {
            alert( "finished" );
          });

        // Perform other work here ...

        // Set another completion function for the request above
        jqxhr.always(function() {
          alert( "second finished" );
        });
</script>

You might want to modify your jQuery code a bit to '#demolist li a' so it specifically selects the text that is in the link rather than the text that is in the li element. That would allow you to have a sub-menu without causing issues. Also since your are specifically selecting the a tag you can access it with $(this).text();.

$('#datebox li a').on('click', function(){
    //$('#datebox').val($(this).text());
    alert($(this).text());
});

I can't replicate that (php 5.3.6):

php > $error = array();
php > $error['something'] = false;
php > $error['somethingelse'] = false;
php > var_dump(empty($error));
bool(false)

php > $error = array();
php > var_dump(empty($error));
bool(true)
php >

exactly where are you doing the empty() call that returns true?

   -Xmx3072m -XX:MaxPermSize=524m as shown in below figure. 
   

For SQL Server 2017 it is : C:\Windows\SysWOW64\SQLServerManager14.msc

For SQL Server 2016 it is : C:\Windows\SysWOW64\SQLServerManager13.msc

For SQL Server 2016 it is :C:\Windows\SysWOW64\SQLServerManager12.msc

and to add it back to the start menu, copy it from the original location provided above and paste it to

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft SQL Server 2017\Configuration Tools\

This would put back the configuration manager under start menu.

Here's your code fixed up. Next forget bindingsource

 var select = "SELECT * FROM tblEmployee";
 var c = new SqlConnection(yourConnectionString); // Your Connection String here
 var dataAdapter = new SqlDataAdapter(select, c); 

 var commandBuilder = new SqlCommandBuilder(dataAdapter);
 var ds = new DataSet();
 dataAdapter.Fill(ds);
 dataGridView1.ReadOnly = true; 
 dataGridView1.DataSource = ds.Tables[0];

Unfortunately, there doesn't appear to be a magic bullet. Bottom line up front: "context".

Google indeed ignores most punctuation, with the following exceptions:

1. Punctuation in popular terms that have particular meanings, like [ C++ ] or [ C# ] (both are names of programming languages), are not ignored.
2. The dollar sign ($) is used to indicate prices. [ nikon 400 ] and [ nikon $400 ] will give different results.
3. The hyphen - is sometimes used as a signal that the two words around it are very strongly connected. (Unless there is no space after the - and a space before it, in which case it is a negative sign.)
4. The underscore symbol _ is not ignored when it connects two words, e.g. [ quick_sort ].

As such, it is not well suited for these types of searchs. Google Code however does have syntax for searching through their code projects, that includes a robust language/syntax for dealing with "special characters". If looking at someone else's code could help solve a problem, this may be an option.

Unfortunately, this is not a limitation unique to google. You may find that your best successes hinge on providing as much 'context' to the problem as possible. If you are searching to find what $- means, providing information about the problem's domain may yield good results.

For example, searching "special perl variables" quickly yields your answer in the first entry on the results page.

If you want to print/write double value at console then use System.out.printf() or System.out.format() methods.

System.out.printf("\n$%10.2f",shippingCost);
System.out.printf("%n$%.2f",shippingCost);

Short answer: Use the change event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.

Single checkbox

Using querySelector.

var checkbox = document.querySelector("input[name=checkbox]");

checkbox.addEventListener('change', function() {
  if (this.checked) {
    console.log("Checkbox is checked..");
  } else {
    console.log("Checkbox is not checked..");
  }
});

<input type="checkbox" name="checkbox" />

Single checkbox with jQuery

$('input[name=checkbox]').change(function() {
  if ($(this).is(':checked')) {
    console.log("Checkbox is checked..")
  } else {
    console.log("Checkbox is not checked..")
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="checkbox" />

Multiple checkboxes

Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll instead of querySelector. Then use Array.filter and Array.map to extract checked values.

// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []

/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/

// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
  checkbox.addEventListener('change', function() {
    enabledSettings = 
      Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
      .filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
      .map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
      
    console.log(enabledSettings)
  })
});

<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Multiple checkboxes with jQuery

let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];

// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
  enabledSettings = checkboxes
    .filter(":checked") // Filter out unchecked boxes.
    .map(function() { // Extract values using jQuery map.
      return this.value;
    }) 
    .get() // Get array.
    
  console.log(enabledSettings);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Since typeof is a compiler extension, there is not really a definition for it, but in the tradition of C it would be an operator, e.g sizeof and _Alignof are also seen as an operators.

And you are mistaken, C has dynamic types that are only determined at run time: variable modified (VM) types.

size_t n = strtoull(argv[1], 0, 0);
double A[n][n];
typeof(A) B;

can only be determined at run time.

You could try using UpdateVersion by Matt Griffith. It's quite old now, but works well. To use it, you simply need to setup a pre-build event which points at your AssemblyInfo.cs file, and the application will update the version numbers accordingly, as per the command line arguments.

As the application is open-source, I've also created a version to increment the version number using the format (Major version).(Minor version).([year][dayofyear]).(increment). I've put the code for my modified version of the UpdateVersion application on GitHub: https://github.com/munr/UpdateVersion

select * from left table where key field not in (select key field from right table)

I tried entering a new line character using an excel Sheet. I entered my data by writing "abc" below a blank cell in Excel and then updated my db using the empty cell above the cell containing "abc" and the cell with data. I copy pasted both the cells in my SSMS. It worked for me

val and var both are used to declare a variable.

var is like general variable and it's known as a mutable variable in kotlin and can be assigned multiple times.

val is like Final variable and it's known as immutable in kotlin and can be initialized only single time.

For more information what is val and var please see below link

http://blog.danlew.net/2017/05/30/mutable-vals-in-kotlin/

I believe you could also do something like this.

from xx in table
where (from yy in string[] 
       select yy).Contains(xx.uid.ToString())
select xx

I do not work with google android but I think you'll find it's not that hard to get this working. If you read the relevant bit of the java tutorial you'll see that a registered cookiehandler gets callbacks from the HTTP code.

So if there is no default (have you checked if CookieHandler.getDefault() really is null?) then you can simply extend CookieHandler, implement put/get and make it work pretty much automatically. Be sure to consider concurrent access and the like if you go that route.

edit: Obviously you'd have to set an instance of your custom implementation as the default handler through CookieHandler.setDefault() to receive the callbacks. Forgot to mention that.

You may use also

select * from pg_tables where schemaname = 'information_schema'

In generall pg* tables allow you to see everything in the db, not constrained to your permissions (if you have access to the tables of course).

After some time researching I've gathered some pieces that made me get to this solution. Once that CookieSyncManager is deprecated, this may be the best way to set a specific cookie for a webview in Kotlin nowadays, you shouldn't need anything else.

private fun setCookie(){
    val webView = WebView(this) // this = context
    val cookieManager = CookieManager.getInstance()
    cookieManager.acceptCookie()

    val domain = "https://www.yourdomain.com/"

    webView.webViewClient = WebViewClient()
    webView.settings.javaScriptEnabled = true

    cookieManager.setCookie(domain,"$cookieKey=$cookieValue")
    cookieManager.setAcceptThirdPartyCookies(webView, true)

    webView.loadUrl(domain)
}

There is an interesting discussion here: http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/307d658a-f677-40f2-bdef-e6352b0bfe9e/ My understanding of this thread is that freeing small allocations are not reflected in Private Bytes or Working Set.

Long story short:

if I call

p=malloc(1000);
free(p);

then the Private Bytes reflect only the allocation, not the deallocation.

if I call

p=malloc(>512k);
free(p);

then the Private Bytes correctly reflect the allocation and the deallocation.

screen.orientation.lock('landscape');

Will force it to change to and stay in landscape mode. Tested on Nexus 5.

We just need to use below query to dump one table data into other table.

Select * into SampleProductTracking_tableDump
from SampleProductTracking;

SampleProductTracking_tableDump is a new table which will be created automatically when using with above query. It will copy the records from SampleProductTracking to SampleProductTracking_tableDump

Assuming Bootstrap and Popper libraries were installed using Nuget package manager, for a web application using Visual Studio, in the Master page file (Site.Master), right below where body tag begins, include the reference to popper.min.js by typing:

<script src="Scripts/umd/popper.min.js"></script>

Here is an image to better display the location:

Notice the reference of the popper library to be added should be the one inside umd folder and not the one outside on Scripts folder.

This should fix the problem.

You can use the Apache Commons StringUtils.substring(String str, int start, int end) static method, which is also null safe.

See: http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringUtils.html#substring%28java.lang.String,%20int,%20int%29

and http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/src-html/org/apache/commons/lang/StringUtils.html#line.1961

The accepted answer to this question is a guide for getting IIS Express to work with webmatrix. I found this guide more useful when trying to get it to work with VS 2010.

I just followed steps 3 & 4 (running IIS Express as administrator) and had to temporarily disable my firewall to get it working.

replace() method will work for this. Here is the code that will help to remove character from string. lets say

j_word = 'Stringtoremove'
word = 'String'    

for letter in word:
    if j_word.find(letter) == -1:
        continue
    else:
       # remove matched character
       j_word = j_word.replace(letter, '', 1)

#Output
j_word = "toremove"

If you are using pandas you can access the index by calling .index of whatever array you wish to mimic. The train_test_split carries over the pandas indices to the new dataframes.

In your code you simply use x1.index and the returned array is the indexes relating to the original positions in x.

What version of Ruby are you using? ruby -v will tell you.

If it's 1.9.2, JSON is included in the standard library.

If you're on 1.8.something then do gem install json and it'll install. Then, in your code do:

require 'rubygems'
require 'json'

Then append to_json to an object and you're good to go:

asdf = {'a' => 'b'} #=> {"a"=>"b"}
asdf.to_json #=> "{"a":"b"}"

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

Can you provide an example, because put should work fine as well?

Documentation -

The type of request to make ("POST" or "GET"); the default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers.

Have the example in fiddle and the form parameters are passed fine (as it is put it will not be appended to url) -

$.ajax({
  url: '/echo/html/',
  type: 'PUT',
  data: "name=John&location=Boston",
  success: function(data) {
    alert('Load was performed.');
  }
});

Demo tested from jQuery 1.3.2 onwards on Chrome.

You have an error in your OrderQuantity column. It is named "OrderQuantity" in the INSERT statement and "OrderQantity" in the table definition.

Also, I don't think you can use NOW() as default value in OrderDate. Try to use the following:

 OrderDate TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

First initialize permission request code

public  static final int PERMISSIONS_MULTIPLE_REQUEST = 123;

Check android version

 private void checkAndroidVersion() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        checkPermission();

    } else {
        // write your logic here
    }

}

check multiple permission code

 private void checkPermission() {
    if (ContextCompat.checkSelfPermission(getActivity(),
            Manifest.permission.READ_EXTERNAL_STORAGE) + ContextCompat
            .checkSelfPermission(getActivity(),
                    Manifest.permission.CAMERA)
            != PackageManager.PERMISSION_GRANTED) {

        if (ActivityCompat.shouldShowRequestPermissionRationale
                (getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE) ||
                ActivityCompat.shouldShowRequestPermissionRationale
                        (getActivity(), Manifest.permission.CAMERA)) {

      Snackbar.make(getActivity().findViewById(android.R.id.content),
                    "Please Grant Permissions to upload profile photo",
                    Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
                    new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            requestPermissions(
                                    new String[]{Manifest.permission
                                            .READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
                                    PERMISSIONS_MULTIPLE_REQUEST);
                        }
                    }).show();
        } else {
            requestPermissions(
                    new String[]{Manifest.permission
                            .READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
                    PERMISSIONS_MULTIPLE_REQUEST);
        }
    } else {
        // write your logic code if permission already granted
    }
}

call back method after grant permission by user

@Override
public void onRequestPermissionsResult(int requestCode,
                                       @NonNull String[] permissions, @NonNull int[] grantResults) {

    switch (requestCode) {
        case PERMISSIONS_MULTIPLE_REQUEST:
            if (grantResults.length > 0) {
               boolean cameraPermission = grantResults[1] == PackageManager.PERMISSION_GRANTED;
               boolean readExternalFile = grantResults[0] == PackageManager.PERMISSION_GRANTED;

                if(cameraPermission && readExternalFile)
                {
                    // write your logic here 
                } else {
                    Snackbar.make(getActivity().findViewById(android.R.id.content),
                        "Please Grant Permissions to upload profile photo",
                        Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
                        new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                requestPermissions(
                                        new String[]{Manifest.permission
                                                .READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
                                        PERMISSIONS_MULTIPLE_REQUEST);
                            }
                        }).show();
                }
           }
           break;
    }
}

you can do synchronous shell operations in nodejs like so:

var execSync = function(cmd) {

    var exec  = require('child_process').exec;
    var fs = require('fs');

    //for linux use ; instead of &&
    //execute your command followed by a simple echo 
    //to file to indicate process is finished
    exec(cmd + " > c:\\stdout.txt && echo done > c:\\sync.txt");

    while (true) {
        //consider a timeout option to prevent infinite loop
        //NOTE: this will max out your cpu too!
        try {
            var status = fs.readFileSync('c:\\sync.txt', 'utf8');

            if (status.trim() == "done") {
                var res = fs.readFileSync("c:\\stdout.txt", 'utf8');
                fs.unlinkSync("c:\\stdout.txt"); //cleanup temp files
                fs.unlinkSync("c:\\sync.txt");
                return res;
            }
        } catch(e) { } //readFileSync will fail until file exists
    }

};

//won't return anything, but will take 10 seconds to run
console.log(execSync("sleep 10")); 

//assuming there are a lot of files and subdirectories, 
//this too may take a while, use your own applicable file path
console.log(execSync("dir /s c:\\usr\\docs\\"));

EDIT - this example is meant for windows environments, adjust for your own linux needs if necessary

For cross-browser support you can try as well imitate a gradient border with :before or :after pseudo elements, depends on what you want to do.

request.data will be empty if request.headers["Content-Type"] is recognized as form data, which will be parsed into request.form. To get the raw data regardless of content type, use request.get_data().

request.data calls request.get_data(parse_form_data=True), which results in the different behavior for form data.

If your host is using suPHP, you can try creating a php.ini file in the same folder as the script and adding:

allow_url_fopen = On

(you can determine this by creating a file and checking which user it was created under: if you, it's suPHP, if "apache/nobody" or not you, then it's a normal PHP mode. You can also make a script

<?php
echo `id`;
?>

To give the same information, assuming shell_exec is not a disabled function)

alt and title are for different things, as already mentioned. While the title attribute will provide a tooltip, alt is also an important attribute, since it specifies text to be displayed if the image can't be displayed. (And in some browsers, such as firefox, you'll also see this text while the image loads)

Another point that I feel should be made is that the alt attribute is required to validate as an XHTML document, whereas the title attribute is just an "extra option," as it were.

Technical Answer

Abstract classes cannot be instantiated - this is by definition and design.

From the JLS, Chapter 8. Classes:

A named class may be declared abstract (§8.1.1.1) and must be declared abstract if it is incompletely implemented; such a class cannot be instantiated, but can be extended by subclasses.

From JSE 6 java doc for Classes.newInstance():

InstantiationException - if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no nullary constructor; or if the instantiation fails for some other reason.

You can, of course, instantiate a concrete subclass of an abstract class (including an anonymous subclass) and also carry out a typecast of an object reference to an abstract type.

A Different Angle On This - Teamplay & Social Intelligence:

This sort of technical misunderstanding happens frequently in the real world when we deal with complex technologies and legalistic specifications.

"People Skills" can be more important here than "Technical Skills". If competitively and aggressively trying to prove your side of the argument, then you could be theoretically right, but you could also do more damage in having a fight / damaging "face" / creating an enemy than it is worth. Be reconciliatory and understanding in resolving your differences. Who knows - maybe you're "both right" but working off slightly different meanings for terms??

Who knows - though not likely, it is possible the interviewer deliberately introduced a small conflict/misunderstanding to put you into a challenging situation and see how you behave emotionally and socially. Be gracious and constructive with colleagues, follow advice from seniors, and follow through after the interview to resolve any challenge/misunderstanding - via email or phone call. Shows you're motivated and detail-oriented.

VB.net, Desktop application. If you need lapsed time in milliseconds:

Dim starts As Integer = My.Computer.Clock.TickCount
Dim ends As Integer = My.Computer.Clock.TickCount
Dim lapsed As Integer = ends - starts

Or you can just include the SELECT statement in the SQL that's invoking the trigger, so its passed in as one of the columns in the trigger row(s). As long as you're certain it will infallibly return only one row (hence one value). (And, of course, it must not return a value that interacts with the logic in the trigger, but that's true in any case.)

If you provide proper date format it should work please recheck once if you have given correct date format in insert values

If you have WinWord, you can copy what you need into that, touch up the results, and then paste that into Confluence. I've found that easier than the other solutions here.

I also tried deleting the database again, called update-database and then add-migration. I ended up with an additional migration that seems not to change anything (see below)

Based on above details, I think you have done last thing first. If you run Update database before Add-migration, it won't update the database with your migration schemas. First you need to add the migration and then run update command.

Try them in this order using package manager console.

PM> Enable-migrations //You don't need this as you have already done it
PM> Add-migration Give_it_a_name
PM> Update-database

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.

If your XML is in a string variable called txt and looks like this:

<address>
  <street>Roble Ave</street>
  <mtfcc>S1400</mtfcc>
  <streetNumber>649</streetNumber>
  <lat>37.45127</lat>
  <lng>-122.18032</lng>
  <distance>0.04</distance>
  <postalcode>94025</postalcode>
  <placename>Menlo Park</placename>
  <adminCode2>081</adminCode2>
  <adminName2>San Mateo</adminName2>
  <adminCode1>CA</adminCode1>
  <adminName1>California</adminName1>
  <countryCode>US</countryCode>
</address>

Then you can parse the XML with Javascript DOM like this:

if (window.DOMParser)
{
    parser = new DOMParser();
    xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.loadXML(txt);
}

And get specific values from the nodes like this:

//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;

//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;

//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;

JSFiddle

Feb. 2019 edit:

In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:

NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_
txt = `_x000D_
<address xmlns:p='example.com/postal' xmlns:s='example.com/street' xmlns:sn='example.com/streetNum'>_x000D_
  <s:street>Roble Ave</s:street>_x000D_
  <sn:streetNumber>649</sn:streetNumber>_x000D_
  <p:postalcode>94025</p:postalcode>_x000D_
</address>`;_x000D_
_x000D_
//Everything else the same_x000D_
if (window.DOMParser)_x000D_
{_x000D_
    parser = new DOMParser();_x000D_
    xmlDoc = parser.parseFromString(txt, "text/xml");_x000D_

You can change the tabs by ctrl-pgup and ctrl-pgdown. On that tab you came from the NERDTree is still selected and you can open another tab.

The HTML5 form validation process is limited to situations where the form is being submitted via a submit button. The Form submission algorithm explicitly says that validation is not performed when the form is submitted via the submit() method. Apparently, the idea is that if you submit a form via JavaScript, you are supposed to do validation.

However, you can request (static) form validation against the constraints defined by HTML5 attributes, using the checkValidity() method. If you would like to display the same error messages as the browser would do in HTML5 form validation, I’m afraid you would need to check all the constrained fields, since the validityMessage property is a property of fields (controls), not the form. In the case of a single constrained field, as in the case presented, this is trivial of course:

function submitform() {
  var f = document.getElementsByTagName('form')[0];
  if(f.checkValidity()) {
    f.submit();
  } else {
    alert(document.getElementById('example').validationMessage);
  }
}

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

Unless you are doing a DB to track historical times more than a century ago, using

Modified datetime DEFAULT ((0)) 

is perfectly safe and sound and allows more elegant queries than '1753-01-01' and more efficient queries than NULL.

However, since first Modified datetime is the time at which the record was inserted, you can use:

Modified datetime NOT NULL DEFAULT (GETUTCDATE())

which avoids the whole issue and makes your inserts easier and safer - as in you don't insert it at all and SQL does the housework :-)

With that in place you can still have elegant and fast queries by using 0 as a practical minimum since it's guranteed to always be lower than any insert-generated GETUTCDATE().

Try with below code sample.it is working for me

var date_input_field = $('input[name="date"]');
    date_input_field .datepicker({
        dateFormat: '/dd/mm/yyyy',
        container: container,
        todayHighlight: true,
        autoclose: true,
    }).on('change', function(selected){
        alert("startDate..."+selected.timeStamp);
    });

For multiple files input using lodash or underscore:

.directive("fileread", [function () {
    return {
        scope: {
            fileread: "="
        },
        link: function (scope, element, attributes) {
            element.bind("change", function (changeEvent) {
                return _.map(changeEvent.target.files, function(file){
                  scope.fileread = [];
                  var reader = new FileReader();
                  reader.onload = function (loadEvent) {
                      scope.$apply(function () {
                          scope.fileread.push(loadEvent.target.result);
                      });
                  }
                  reader.readAsDataURL(file);
                });
            });
        }
    }
}]);

I'm developing tiny JS library called mutabor (https://github.com/eskat0n/mutabor) which intended to simplify usage of DOM Mutation Events. See demo.html for examples.

Regret to say, but Both Otacku's and @clatonh's methods aren't working for me - neither have Outlook Bitness nor {90140000-0011-0000-1000-0000000FF1CE} in registry (for 64-bit Office without Outlook installed).

The only way I have found, though, not via the registry, is to check bitness for one of the Office executables with the use of the Windows API function GetBinaryType (since Windows 2000 Professional).

For example, you can check the bitness of Winword.exe, which path is stored under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Winword.exe.

Here is the MFC code fragment:

CRegKey rk;
if (ERROR_SUCCESS == rk.Open(HKEY_LOCAL_MACHINE, 
  "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\Winword.exe", 
  KEY_READ)) {
    CString strWinwordPath;
    DWORD dwSize = MAX_PATH;
    if (ERROR_SUCCESS == rk.QueryStringValue(strWinwordPath, 
        strWinwordPath.GetBuffer(MAX_PATH), &dwSize)) {
            strWinwordPath.ReleaseBuffer();
            DWORD dwBinaryType;
            if (::GetBinaryType(strWinwordPath, &dwBinaryType)) {
                if (SCS_64BIT_BINARY == dwBinaryType) {
                    // Detected 64-bit Office 
                } else {
                    // Detected 32-bit Office 
                }
            } else {
                // Failed
            }
        } else {
            // Failed
        }
    } else {
    // Failed
}

Try this:

                Grid grid = new Grid(); //Define the grid
                for (int i = 0; i < 36; i++) //Add 36 rows
                {
                    ColumnDefinition columna = new ColumnDefinition()
                    {
                        Name = "Col_" + i,
                        Width = new GridLength(32.5),
                    };
                    grid.ColumnDefinitions.Add(columna);
                }

                for (int i = 0; i < 36; i++) //Add 36 columns
                {
                    RowDefinition row = new RowDefinition();
                    row.Height = new GridLength(40, GridUnitType.Pixel);
                    grid.RowDefinitions.Add(row);
                }

                for (int i = 0; i < 36; i++)
                {
                    for (int j = 0; j < 36; j++)
                    {
                        Label t1 = new Label()
                        {
                            FontSize = 10,
                            FontFamily = new FontFamily("consolas"),
                            FontWeight = FontWeights.SemiBold,
                            BorderBrush = Brushes.LightGray,
                            BorderThickness = new Thickness(2),
                            HorizontalContentAlignment = HorizontalAlignment.Center,
                            VerticalContentAlignment = VerticalAlignment.Center,
                        };
                        Grid.SetRow(t1, i);
                        Grid.SetColumn(t1, j);
                        grid.Children.Add(t1); //Add the Label Control to the Grid created
                    }
                }

I had the same problem before and i fixed it by creating the same table in a new sheet and deleting all the name ranges associated to the table, i believe whene you're using listobjects you're not alowed to have name ranges contained within your table hope that helps thanks

I would recommend you look at getting the anaconda package, it will install and configure Sklearn and its dependencies.

https://www.continuum.io

The || operator is "concatenate" - it joins together the two strings of its operands.

From http://www.sqlite.org/lang_expr.html

For padding, the seemingly-cheater way I've used is to start with your target string, say '0000', concatenate '0000423', then substr(result, -4, 4) for '0423'.

Update: Looks like there is no native implementation of "lpad" or "rpad" in SQLite, but you can follow along (basically what I proposed) here: http://verysimple.com/2010/01/12/sqlite-lpad-rpad-function/

-- the statement below is almost the same as
-- select lpad(mycolumn,'0',10) from mytable

select substr('0000000000' || mycolumn, -10, 10) from mytable

-- the statement below is almost the same as
-- select rpad(mycolumn,'0',10) from mytable

select substr(mycolumn || '0000000000', 1, 10) from mytable

Here's how it looks:

SELECT col1 || '-' || substr('00'||col2, -2, 2) || '-' || substr('0000'||col3, -4, 4)

it yields

"A-01-0001"
"A-01-0002"
"A-12-0002"
"C-13-0002"
"B-11-0002"

You can do something like this to read 10 bytes:

char buffer[10];
read(STDIN_FILENO, buffer, 10);

remember read() doesn't add '\0' to terminate to make it string (just gives raw buffer).

To read 1 byte at a time:

char ch;
while(read(STDIN_FILENO, &ch, 1) > 0)
{
 //do stuff
}

and don't forget to #include <unistd.h>, STDIN_FILENO defined as macro in this file.

There are three standard POSIX file descriptors, corresponding to the three standard streams, which presumably every process should expect to have:

Integer value   Name
       0        Standard input (stdin)
       1        Standard output (stdout)
       2        Standard error (stderr)

So instead STDIN_FILENO you can use 0.

Edit:
In Linux System you can find this using following command:

$ sudo grep 'STDIN_FILENO' /usr/include/* -R | grep 'define'
/usr/include/unistd.h:#define   STDIN_FILENO    0   /* Standard input.  */

Notice the comment /* Standard input. */

very old question, i know. but with the new f-strings (starting from python 3.6) there are fresh options. so here for completeness:

from datetime import datetime

dt = datetime.now()

# str.format
strg = '{:%B %d, %Y}'.format(dt)
print(strg)  # July 22, 2017

# datetime.strftime
strg = dt.strftime('%B %d, %Y')
print(strg)  # July 22, 2017

# f-strings in python >= 3.6
strg = f'{dt:%B %d, %Y}'
print(strg)  # July 22, 2017

strftime() and strptime() Behavior explains what the format specifiers mean.

Basically the same answer as here, but easy to copy/paste, and it just works ;-)

  import java.io.FileWriter;

  public void saveToFile(String data, String filename) {
    try (
      FileWriter fw = new FileWriter(filename)) {
      fw.write(data);
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

In MySQL, @variable indicates a user-defined variable. You can define your own.

SET @a = 'test';
SELECT @a;

Outside of stored programs, a variable, without @, is a system variable, which you cannot define yourself.

The scope of this variable is the entire session. That means that while your connection with the database exists, the variable can still be used.

This is in contrast with MSSQL, where the variable will only be available in the current batch of queries (stored procedure, script, or otherwise). It will not be available in a different batch in the same session.

int negInt = -System.Math.Abs(myInt)

I would use the first one. It is clear to see right away what it does. I dont think the null check is necessary here.

And You Can Select the First One and Object Also Shown here true,false,flase

If you're wondering about what glob.glob has done on your system in the past and cannot add a sorted call, the ordering will be consistent on Mac HFS+ filesystems and will be traversal order on other Unix systems. So it will likely have been deterministic unless the underlying filesystem was reorganized which can happen if files were added, removed, renamed, deleted, moved, etc...

If you are lucky and need to care only for recent browsers, you can use:

document.querySelectorAll('input[type=text]')

"recent" means not IE6 and IE7

After Ctrl+End, you can do the Ctrl+A to select all in the buffer and then paste into Excel. Excel even put each Oracle column into its own column instead of squishing the whole row into one column. Nice..

Apple users can download your .apk file, however they cannot run it. It is a different file format than iPhone apps (.ipa)

128M == 134217728, the number you are seeing.

The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.

Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.

A CHAR(x) column can only have exactly x characters.
A VARCHAR(x) column can have up to x characters.

Since your MD5 hashes will always be the same size, you should probably use a CHAR.

However, you shouldn't be using MD5 in the first place; it has known weaknesses.
Use SHA2 instead.
If you're hashing passwords, you should use bcrypt.

import time 

startTime = time.time()
# Your code here !
print ('The script took {0} second !'.format(time.time() - startTime))

The previous code works for me with no problem !

Try this:

((Button)btn).getCompoundDrawables()[0].setAlpha(btn.isEnabled() ? 255 : 100);

I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer in this mailinglist post).

For example, numpy seems to use buffer for efficient data storage:

import numpy
a = numpy.ndarray(1000000)

the a.data is a:

<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

As of PHP7.3 you can directly access the last key in (the outer level of) an array with array_key_last()

The definitively puts much of the debate on this page to bed. It is hands-down the best performer, suffers no side effects, and is a direct, intuitive, single-call technique to deliver exactly what this question seeks.

A rough benchmark as proof: https://3v4l.org/hO1Yf

array_slice() + key():  1.4
end() + key():         13.7
array_key_last():       0.00015

*test array contains 500000 elements, microtime repeated 100x then averaged then multiplied by 1000 to avoid scientific notation. Credit to @MAChitgarha for the initial benchmark commented under @TadejMagajna's answer.

This means you can retrieve the value of the final key without:

1. moving the array pointer (which requires two lines of code) or
2. sorting, reversing, popping, counting, indexing an array of keys, or any other tomfoolery

This function was long overdue and a welcome addition to the array function tool belt that improves performance, avoids unwanted side-effects, and enables clean/direct/intuitive code.

Here is a demo:

$array = ["a" => "one", "b" => "two", "c" => "three"];
if (!function_exists('array_key_last')) {
    echo "please upgrade to php7.3";
} else {
    echo "First Key: " , key($array) , "\n";
    echo "Last Key: " , array_key_last($array) , "\n";
    next($array);                 // move array pointer to second element
    echo "Second Key: " , key($array) , "\n";
    echo "Still Last Key: " , array_key_last($array);
}

Output:

First Key: a
Last Key: c     // <-- unaffected by the pointer position, NICE!
Second Key: b
Last Key: c     // <-- unaffected by the pointer position, NICE!

Some notes:

• array_key_last() is the sibling function of array_key_first().
• Both of these functions are "pointer-ignorant".
• Both functions return null if the array is empty.
• Discarded sibling functions (array_value_first() & array_value_last()) also would have offered the pointer-ignorant access to bookend elements, but they evidently failed to garner sufficient votes to come to life.

Here are some relevant pages discussing the new features:

• https://laravel-news.com/outer-array-functions-php-7-3
• https://kinsta.com/blog/php-7-3/#array-key-first-last
• https://wiki.php.net/rfc/array_key_first_last

p.s. If anyone is weighing up some of the other techniques, you may refer to this small collection of comparisons: (Demo)

Duration of array_slice() + key():     0.35353660583496
Duration of end() + key():             6.7495584487915
Duration of array_key_last():          0.00025749206542969
Duration of array_keys() + end():      7.6123380661011
Duration of array_reverse() + key():   6.7875385284424
Duration of array_slice() + foreach(): 0.28870105743408

Another way is to compare the character with an empty object, i don't really know's why it works, but it works :

for (let i = 1; i <= 26; i++) {
   const letter = (i + 9).toString(36).toUpperCase();
   console.log('letter', letter, 'is upper', letter<{}); // returns true
}
for (let i = 1; i <= 26; i++) {
   const letter = (i + 9).toString(36);
   console.log('letter', letter, 'is upper', letter<{}); // returns false
}

so in a function :

function charIsUpper(character) {
   return character<{};
}

EDIT: it doesn't work with accents and diacritics, so it's possible to remove it

function charIsUpper(character) {
   return character
           .normalize('NFD')
           .replace(/[\u0300-\u036f]/g, '')<{};
}

It may be that your condas channels need a wakeup call... with

conda update --all

For me it worked. More information: https://www.anaconda.com/keeping-anaconda-date/

Use DBNull.Value.Equals on the object without converting it to a string.

Here's an example:

   if (! DBNull.Value.Equals(row[fieldName])) 
   {
      //not null
   }
   else
   {
      //null
   }

for large data set and multiple value drop down it is better to use ng-options rather than ng-repeat.

ng-repeat is slow because it loops over all coming values but ng-options simply display to the select option.

ng-options='state.StateCode as state.StateName for state in States'>

much much faster than

<option ng-repeat="state in States" value="{{state.StateCode}}">
    {{state.StateName }}
</option>

Here is the missing piece. You need to pass 'recursive' flag as third argument (boolean true) in mkdir call like this:

mkdir('path/to/directory', 0755, true);

Java ships in 2 versions: JRE & SDK (used to be called JDK)

The JRE in addition to not containing the compiler, also doesn't contain all of the libraries available in the JDK (tools.jar is one of them)

When you download Java at: http://java.sun.com/javase/downloads/index.jsp, make sure to select the JDK version and install it. If you have both a JDK & JRE, make sure that ANT is using the JDK, you can check JAVA_HOME (environment variable), and on the commandline if you do "javac -version" you should get a version description.

If you simply want to create an empty data frame and fill it with some incoming data frames later, try this:

newDF = pd.DataFrame() #creates a new dataframe that's empty
newDF = newDF.append(oldDF, ignore_index = True) # ignoring index is optional
# try printing some data from newDF
print newDF.head() #again optional 

In this example I am using this pandas doc to create a new data frame and then using append to write to the newDF with data from oldDF.

If I have to keep appending new data into this newDF from more than one oldDFs, I just use a for loop to iterate over pandas.DataFrame.append()

Check this snip out.

# reading the JSON data using json.load()
file = 'data.json'
with open(file) as train_file:
    dict_train = json.load(train_file)

# converting json dataset from dictionary to dataframe
train = pd.DataFrame.from_dict(dict_train, orient='index')
train.reset_index(level=0, inplace=True)

Hope it helps :)

the ultimate answer: change the owner of that directory to whoever you are

sudo chown -R `whoami` /usr/local/include

which is also recommended by brew if you run brew doctor

In your terminal run: docker exec -it container_name /bin/bash Then: mysql

You can't change the enumerable collection while it is being enumerated, so you will have to make your changes before or after enumerating.

The for loop is a nice alternative, but if your IEnumerable collection does not implement ICollection, it is not possible.

Either:

1) Copy collection first. Enumerate the copied collection and change the original collection during the enumeration. (@tvanfosson)

or

2) Keep a list of changes and commit them after the enumeration.

Requirement : Accessing the static Resources (images/videos., etc.,) from outside of WEBROOT directory or from local disk

Step 1 :
Create a folder under webapps of tomcat server., let us say the folder name is myproj

Step 2 :
Under myproj create a WEB-INF folder under this create a simple web.xml

code under web.xml

<web-app>
</web-app>

Directory Structure for the above two steps

c:\programfile\apachesoftwarefoundation\tomcat\...\webapps
                                                            |
                                                            |---myproj
                                                            |   |
                                                            |   |---WEB-INF
                                                                |   |
                                                                    |---web.xml

Step 3:
Now create a xml file with name myproj.xml under the following location

c:\programfile\apachesoftwarefoundation\tomcat\conf\catalina\localhost

CODE in myproj.xml:

<Context path="/myproj/images" docBase="e:/myproj/" crossContext="false" debug="0" reloadable="true" privileged="true" /> 

Step 4:
4 A) Now create a folder with name myproj in E drive of your hard disk and create a new

folder with name images and place some images in images folder (e:myproj\images\)

Let us suppose myfoto.jpg is placed under e:\myproj\images\myfoto.jpg

4 B) Now create a folder with name WEB-INF in e:\myproj\WEB-INF and create a web.xml in WEB-INF folder

Code in web.xml

<web-app>
</web-app>

Step 5:
Now create a .html document with name index.html and place under e:\myproj

CODE under index.html Welcome to Myproj

The Directory Structure for the above Step 4 and Step 5 is as follows

E:\myproj
    |--index.html
    |
    |--images
    |     |----myfoto.jpg
    |
    |--WEB-INF
    |     |--web.xml

Step 6:
Now start the apache tomcat server

Step 7:
open the browser and type the url as follows

http://localhost:8080/myproj    

then u display the content which is provided in index.html

Step 8:
To Access the Images under your local hard disk (outside of webroot)

http://localhost:8080/myproj/images/myfoto.jpg

If your passphrase is to unlock your SSH key and you don't have ssh-agent, but do have sshd (the SSH daemon) installed on your machine, do:

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys;
ssh localhost -i ~/.ssh/id_rsa

Where ~/.ssh/id_rsa.pub is the public key, and ~/.ssh/id_rsa is the private key.

select substring(your_field, CHARINDEX(';',your_field)+1 ,CHARINDEX('[',your_field)-CHARINDEX(';',your_field)-1) from your_table

Can't get the others to work. I believe you just want what is in between ';' and '[' in all cases regardless of how long the string in between is. After specifying the field in the substring function, the second argument is the starting location of what you will extract. That is, where the ';' is + 1 (fourth position - the c), because you don't want to include ';'. The next argument takes the location of the '[' (position 14) and subtracts the location of the spot after the ';' (fourth position - this is why I now subtract 1 in the query). This basically says substring(field,location I want substring to begin, how long I want substring to be). I've used this same function in other cases. If some of the fields don't have ';' and '[', you'll want to filter those out in the "where" clause, but that's a little different than the question. If your ';' was say... ';;;', you would use 3 instead of 1 in the example. Hope this helps!

If you using Anaconda3

Just put

conda install -c conda-forge matplotlib

Close, you can use

$('#select_2 option:selected').html()

if netclient.p is inside a JAR file, it won't have a path because that file is located inside other file. in that case, the best path you can have is really file:/path/to/jarfile/bot.jar!/config/netclient.p.

Can also be done this way..

regex=re.compile('^hello')

## THIS WAY YOU CAN CHECK FOR MULTIPLE STRINGS
## LIKE
## regex=re.compile('^hello|^john|^world')

if re.match(regex, somestring):
    print("Yes")

Just add min-height:100% and min-width:100% and it will work. I had the same problem. You don't need a 3th wrapper

Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express (%PROGRAMFILES(x86)%\IIS Express on x64 architectures) and its called iisexpress.exe.

To see all the possible command-line options, just run:

iisexpress /?

and the program detailed help will show up.

If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.

There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config): the /site and /siteId.

With the first one, you can launch a specific site by name:

iisexpress /site:SiteName

And with the latter, you can launch by specifying the ID:

iisexpress /siteId:SiteId

With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.

Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):

iisexpress /path:FullSitePath

This covers the basic IISExpress usage from the command line.

x=1 while x<=100: print(x) x=x+3

For linux users, and to sum up and add to what others have said here, you should know the following:

1. Global variables are not evil. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

For HttpEntity, the below answer works

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

For reference: How to POST form data with Spring RestTemplate?

This is equivalent to the path of the script:

%~dp0

This uses the batch parameter extension syntax. Parameter 0 is always the script itself.

If your script is stored at C:\example\script.bat, then %~dp0 evaluates to C:\example\.

ss64.com has more information about the parameter extension syntax. Here is the relevant excerpt:

You can get the value of any parameter using a % followed by it's numerical position on the command line.

[...]

When a parameter is used to supply a filename then the following extended syntax can be applied:

[...]

%~d1 Expand %1 to a Drive letter only - C:

[...]

%~p1 Expand %1 to a Path only e.g. \utils\ this includes a trailing \ which may be interpreted as an escape character by some commands.

[...]

The modifiers above can be combined:

%~dp1 Expand %1 to a drive letter and path only

[...]

You can get the pathname of the batch script itself with %0, parameter extensions can be applied to this so %~dp0 will return the Drive and Path to the batch script e.g. W:\scripts\

select Count(distinct columnName) as columnNameCount from tableName 

Also, look at your perfmon counters. They can tell you where a lot of that cpu time is being spent. Here's a link to the most common counters to use:

I know it's tempting to use drag and drop angular modules created by other devs - but actually, unless you are doing something non-standard like dynamically adding / removing rows from the ng-repeated data set by calling $http services chance are you really don't need a directive based solution, so if you do go this direction you probably just created extra watchers you don't actually need.

What this implementation provides:

• Pagination is always correct
• Filtering is always correct (even if you add custom filters but of course they just need to be in the same closure)

The implementation is easy. Just use angular's version of jQuery dom ready from your view's controller:

Inside your controller:

'use strict';

var yourApp = angular.module('yourApp.yourController.controller', []);

yourApp.controller('yourController', ['$scope', '$http', '$q', '$timeout', function ($scope, $http, $q, $timeout) {

    $scope.users = [
        {
            email: '[email protected]',
            name: {
                first: 'User',
                last: 'Last Name'
            },
            phone: '(416) 555-5555',
            permissions: 'Admin'
        },
        {
            email: '[email protected]',
            name: {
                first: 'First',
                last: 'Last'
            },
            phone: '(514) 222-1111',
            permissions: 'User'
        }
    ];

    angular.element(document).ready( function () {
         dTable = $('#user_table')
         dTable.DataTable();
     });

}]);

Now in your html view can do:

<div class="table table-data clear-both" data-ng-show="viewState === possibleStates[0]">
        <table id="user_table" class="users list dtable">
            <thead>
                <tr>
                    <th>E-mail</th>
                    <th>First Name</th>
                    <th>Last Name</th>
                    <th>Phone</th>
                    <th>Permissions</th>
                    <th class="blank-cell"></th>
                </tr>
            </thead>
            <tbody>
                <tr data-ng-repeat="user in users track by $index">
                    <td>{{ user.email }}</td>
                    <td>{{ user.name.first }}</td>
                    <td>{{ user.name.last }}</td>
                    <td>{{ user.phone }}</td>
                    <td>{{ user.permissions }}</td>
                    <td class="users controls blank-cell">
                        <a class="btn pointer" data-ng-click="showEditUser( $index )">Edit</a>
                    </td>
                </tr>
            </tbody>
        </table>
    </div>

You can use SQLAlchemy's or_ function to search in more than one column (the underscore is necessary to distinguish it from Python's own or).

Here's an example:

from sqlalchemy import or_
query = meta.Session.query(User).filter(or_(User.firstname.like(searchVar),
                                            User.lastname.like(searchVar)))

Replaced the reader declaration with this one and now it works!

Dim reader As New StreamReader(filetoimport.Text, Encoding.Default)

Encoding.Default represents the ANSI code page that is set under Windows Control Panel.

You also can do this very easily with awk, if you're willing to consider a different tool:

echo "UPPER" | awk '{print tolower($0)}'

In pthread_exit, ret is an input parameter. You are simply passing the address of a variable to the function.

In pthread_join, ret is an output parameter. You get back a value from the function. Such value can, for example, be set to NULL.

Long explanation:

In pthread_join, you get back the address passed to pthread_exit by the finished thread. If you pass just a plain pointer, it is passed by value so you can't change where it is pointing to. To be able to change the value of the pointer passed to pthread_join, it must be passed as a pointer itself, that is, a pointer to a pointer.

You can use UIGraphicsBeginImageContext method to set the size of image same that of view.

Syntax : void UIGraphicsBeginImageContext(CGSize size);

 #define IMAGE(imageName) (UIImage *)[UIImage imageWithContentsOfFile:
  [[NSBundle mainBundle] pathForResource:imageName ofType:IMAGE_TYPE_PNG]]

        UIGraphicsBeginImageContext(self.view.frame.size);
        [[UIImage imageNamed:@“MyImage.png"] drawInRect:self.view.bounds];
        UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

    self.view.backgroundColor = [UIColor colorWithPatternImage:IMAGE(@"mainBg")];

From Sort an array of associative arrays by value of given key in php:

by using usort (http://php.net/usort) , we can sort an array in ascending and descending order. just we need to create a function and pass it as parameter in usort. As per below example used greater than for ascending order if we passed less than condition then it's sort in descending order. Example :

$array = array(
  array('price'=>'1000.50','product'=>'test1'),
  array('price'=>'8800.50','product'=>'test2'),
  array('price'=>'200.0','product'=>'test3')
);

function cmp($a, $b) {
  return $a['price'] > $b['price'];
}

usort($array, "cmp");
print_r($array);

Output:

Array
 (
    [0] => Array
        (
            [price] => 200.0
            [product] => test3
        )

    [1] => Array
        (
            [price] => 1000.50
            [product] => test1
        )

    [2] => Array
        (
            [price] => 8800.50
            [product] => test2
        )
  )

Here is the xrange way:

list(0 for i in xrange(0,5)) 

I believe there are two answers. One using 'pure' Javascript with IIFE function to hide its auxiliary construction functions. And the other using a NodeJS module to also hide its auxiliary construction functions.

I will show only the example with a NodeJS module.

Class Vector2d.js:

/*

    Implement a class of type Vetor2d with three types of constructors.

*/

// If a constructor function is successfully executed,
// must have its value changed to 'true'.let global_wasExecuted = false;  
global_wasExecuted = false;   

//Tests whether number_value is a numeric type
function isNumber(number_value) {
    
    let hasError = !(typeof number_value === 'number') || !isFinite(number_value);

    if (hasError === false){
        hasError = isNaN(number_value);
    }

    return !hasError;
}

// Object with 'x' and 'y' properties associated with its values.
function vector(x,y){
    return {'x': x, 'y': y};
}

//constructor in case x and y are 'undefined'
function new_vector_zero(x, y){

    if (x === undefined && y === undefined){
        global_wasExecuted = true;
        return new vector(0,0);
    }
}

//constructor in case x and y are numbers
function new_vector_numbers(x, y){

    let x_isNumber = isNumber(x);
    let y_isNumber = isNumber(y);

    if (x_isNumber && y_isNumber){
        global_wasExecuted = true;
        return new vector(x,y);
    }
}

//constructor in case x is an object and y is any
//thing (he is ignored!)
function new_vector_object(x, y){

    let x_ehObject = typeof x === 'object';
    //ignore y type

    if (x_ehObject){

        //assigns the object only for clarity of code
        let x_object = x;

        //tests whether x_object has the properties 'x' and 'y'
        if ('x' in x_object && 'y' in x_object){

            global_wasExecuted = true;

            /*
            we only know that x_object has the properties 'x' and 'y',
            now we will test if the property values ??are valid,
            calling the class constructor again.            
            */
            return new Vector2d(x_object.x, x_object.y);
        }

    }
}


//Function that returns an array of constructor functions
function constructors(){
    let c = [];
    c.push(new_vector_zero);
    c.push(new_vector_numbers);
    c.push(new_vector_object);

    /*
        Your imagination is the limit!
        Create as many construction functions as you want.    
    */

    return c;
}

class Vector2d {

    constructor(x, y){

        //returns an array of constructor functions
        let my_constructors = constructors(); 

        global_wasExecuted = false;

        //variable for the return of the 'vector' function
        let new_vector;     

        //traverses the array executing its corresponding constructor function
        for (let index = 0; index < my_constructors.length; index++) {

            //execute a function added by the 'constructors' function
            new_vector = my_constructors[index](x,y);
            
            if (global_wasExecuted) {
            
                this.x = new_vector.x;
                this.y = new_vector.y;

                break; 
            };
        };
    }

    toString(){
        return `(x: ${this.x}, y: ${this.y})`;
    }

}

//Only the 'Vector2d' class will be visible externally
module.exports = Vector2d;  

The useVector2d.js file uses the Vector2d.js module:

const Vector = require('./Vector2d');

let v1 = new Vector({x: 2, y: 3});
console.log(`v1 = ${v1.toString()}`);

let v2 = new Vector(1, 5.2);
console.log(`v2 = ${v2.toString()}`);

let v3 = new Vector();
console.log(`v3 = ${v3.toString()}`);

Terminal output:

v1 = (x: 2, y: 3)
v2 = (x: 1, y: 5.2)
v3 = (x: 0, y: 0)

With this we avoid dirty code (many if's and switch's spread throughout the code), difficult to maintain and test. Each building function knows which conditions to test. Increasing and / or decreasing your building functions is now simple.

Rules:

1. Do what the code you are editing does
2. If #1 doesn't apply, use camelCase, no underscores

Here is a function to do it and seems reasonably fast.

endv<-function(vec,val) 
{
if(val>length(vec))
{
stop("Length of value greater than length of vector")
}else
{
vec[((length(vec)-val)+1):length(vec)]
}
}

USAGE:

test<-c(0,1,1,0,0,1,1,NA,1,1)
endv(test,5)
endv(LETTERS,5)

<div id='element_123_wrapper_text'>My sample DIV</div>

The Operator ^ - Match elements that starts with given value

div[id^="element_123"] {

}

The Operator $ - Match elements that ends with given value

div[id$="wrapper_text"] {

}

The Operator * - Match elements that have an attribute containing a given value

div[id*="wrapper_text"] {

}

The find command will take long time, the fastest way to search for file is using locate command, which looks for file names (and path) in a indexed database (updated by command updatedb).

The result will appear immediately with a simple command:

locate {file-name-or-path}

If the command is not found, you need to install mlocate package and run updatedb command first to prepare the search database for the first time.

This helped me at the end:

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

... You can then use copy() to duplicate a PHP file, although this sounds incredibly inefficient.

yum install python-devel will work.

If yum doesn't work then use

apt-get install python-dev

This is the solution, which is worked for me.

<p:commandButton id="b1" value="Save" process="userGroupSetupForm"
                    actionListener="#{userGroupSetupController.saveData()}" 
                    update="growl userGroupList userGroupSetupForm" />

Here, process="userGroupSetupForm" atrribute is mandatory for Ajax call. actionListener is calling a method from @ViewScope Bean. Also updating growl message, Datatable: userGroupList and Form: userGroupSetupForm.

There are many Date manipulation modules on CPAN. My particular favourite is DateTime and you can use the strptime modules to parse dates in arbitrary formats. There are also many DateTime::Format modules on CPAN for handling specialised date formats, but strptime is the most generic.

For easy fix follow these steps:

1. goto: https://docs.microsoft.com/en-us/sql/connect/jdbc/building-the-connection-url#Connectingintegrated
2. Download the JDBC file and extract to your preferred location
3. open the auth folder matching your OS x64 or x86
4. copy sqljdbc_auth.dll file
5. paste in: C:\Program Files\Java\jdk_version\bin
6. restart either eclipse or netbeans

You can use this PHP library available on packagist:

https://github.com/CoreProc/gcm-php

After installing it you can do this:

$gcmClient = new GcmClient('your-gcm-api-key-here');

$message = new Message($gcmClient);

$message->addRegistrationId('xxxxxxxxxx');
$message->setData([
    'title' => 'Sample Push Notification',
    'message' => 'This is a test push notification using Google Cloud Messaging'
]);

try {

    $response = $message->send();

    // The send() method returns a Response object
    print_r($response);

} catch (Exception $exception) {

    echo 'uh-oh: ' . $exception->getMessage();

}

function Redirect($url, $permanent = false)
{
    if (headers_sent() === false)
    {
        header('Location: ' . $url, true, ($permanent === true) ? 301 : 302);
    }

    exit();
}

Redirect('http://www.google.com/', false);

Don't forget to die()/exit()!

Install prerequisites VMware Tools for LinuxOS:

If you have RHEL/CentOS:

yum install perl gcc make kernel-headers kernel-devel -y

If you have Ubuntu/Debian:

sudo apt-get -y install linux-headers-server build-essential

• build-essential, also install: dpkg-dev, g++, gcc, lib6-dev, libc-dev, make

Extracted from: http://www.sysadmit.com/2016/01/vmware-tools-linux-instalar-requisitos.html

You can use Local storage.

local storage is same as session. the data will be removed when you close the browser.

<script> 
localStorage.setItem('lastname','Smith');

alert(localStorage.getItem('lastname'));
</script>

Edit: @Naveen comment below is correct. You can use session storage instead. (https://www.w3schools.com/jsref/prop_win_sessionstorage.asp) Thanks.

<script> 
sessionStorage.setItem('lastname','Smith');

alert(sessionStorage.getItem('lastname'));
</script>

This fixed issues for me:

<style>
.super-centered {
    position:absolute; 
    width:100%;
    height:100%;
    text-align:center; 
    vertical-align:middle;
    z-index: 9999;
}
</style>

<table class="super-centered"><tr><td style="width:100%;height:100%;" align="center"     valign="middle" > 
<img alt="Loading ..." src="/ALHTheme/themes/html/ALHTheme/images/loading.gif">
</td></tr></table>

If you want to edit that file (or any file in generally), you can't edit it simply writing its name in terminal. You must to use a command to a text editor to do this. For example:

nano ~/.bashrc

or

gedit ~/.bashrc

And in general, for any type of file:

xdg-open ~/.bashrc

Writing only ~/.bashrc in terminal, this will try to execute that file, but .bashrc file is not meant to be an executable file. If you want to execute the code inside of it, you can source it like follow:

source ~/.bashrc

or simple:

. ~/.bashrc 

I solved this error by including a get and post request in my controller: method={RequestMethod.POST, RequestMethod.GET}

I have a lib that uses trim. so solved it by using the following code.

String.prototype.trim = String.prototype.trim || function(){ return jQuery.trim(this); };

The easiest might be:

Array(1, 2, 3) :+ 4

Actually, Array can be implcitly transformed in a WrappedArray

If the user successful login into your Node app, I'm thinking that you are using Express, isn't ? Well you can redirect easy by using res.redirect. Like:

app.post('/auth', function(req, res) {
  // Your logic and then redirect
  res.redirect('/user_profile');
});

For me, Added the following to my server's web.config file:

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="Access-Control-Allow-Origin" value="https://other.domain.com" />
            <add name="Access-Control-Allow-Methods" value="GET,POST,OPTIONS,PUT,DELETE" />
            <add name="Access-Control-Allow-Headers" value="Content-Type,X-Requested-With" />
        </customHeaders>
    </httpProtocol>
<system.webServer>
