I have been working on an open source project that allows you to hot replace classes over and above what hot swap allows: https://github.com/fakereplace/fakereplace

It may or may not work for you, but any feedback is appreciated

Brief syntax lesson

Cells(Row, Column) identifies a cell. Row must be an integer between 1 and the maximum for version of Excel you are using. Column must be a identifier (for example: "A", "IV", "XFD") or a number (for example: 1, 256, 16384)

.Cells(Row, Column) identifies a cell within a sheet identified in a earlier With statement:

With ActiveSheet
  :
  .Cells(Row,Column)
  :
End With

If you omit the dot, Cells(Row,Column) is within the active worksheet. So wsh = ActiveWorkbook wsh.Range is not strictly necessary. However, I always use a With statement so I do not wonder which sheet I meant when I return to my code in six months time. So, I would write:

With ActiveSheet
  :
  .Range.  
  :
End With

Actually, I would not write the above unless I really did want the code to work on the active sheet. What if the user has the wrong sheet active when they started the macro. I would write:

With Sheets("xxxx")
  :
  .Range.  
  :
End With

because my code only works on sheet xxxx.

Cells(Row,Column) identifies a cell. Cells(Row,Column).xxxx identifies a property of the cell. Value is a property. Value is the default property so you can usually omit it and the compiler will know what you mean. But in certain situations the compiler can be confused so the advice to include the .Value is good.

Cells(Row,Column) like "*Miami*" will give True if the cell is "Miami", "South Miami", "Miami, North" or anything similar.

Cells(Row,Column).Value = "Miami" will give True if the cell is exactly equal to "Miami". "MIAMI" for example will give False. If you want to accept MIAMI, use the lower case function:

Lcase(Cells(Row,Column).Value) = "miami"  

My suggestions

Your sample code keeps changing as you try different suggestions which I find confusing. You were using Cells(Row,Column) <> "Miami" when I started typing this.

Use

If Cells(i, "A").Value like "*Miami*" And Cells(i, "D").Value like "*Florida*" Then
  Cells(i, "C").Value = "BA"

if you want to accept, for example, "South Miami" and "Miami, North".

Use

If Cells(i, "A").Value = "Miami" And Cells(i, "D").Value like "Florida" Then
  Cells(i, "C").Value = "BA"

if you want to accept, exactly, "Miami" and "Florida".

Use

If Lcase(Cells(i, "A").Value) = "miami" And _
   Lcase(Cells(i, "D").Value) = "florida" Then
  Cells(i, "C").Value = "BA"

if you don't care about case.

You can call the stat() function and use the S_ISREG() macro on the st_mode field of the stat structure in order to determine if your path points to a regular file:

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

int is_regular_file(const char *path)
{
    struct stat path_stat;
    stat(path, &path_stat);
    return S_ISREG(path_stat.st_mode);
}

Note that there are other file types besides regular and directory, like devices, pipes, symbolic links, sockets, etc. You might want to take those into account.

For anyone wondering where the settings for apps from the Microsoft Store are, they are either in WindowsApps, which is very locked down, but you can get there by opening your app and then opening the file path with Task-Manager.

But it's more likely that they are saved in C:\Users\[USERNAME]\AppData\Local\Packages\[NUMBERS][COMPANY].[APPLICATION]_[RANDOMDATA]\LocalCache\Local\[COMPANY]\[APPLICATION].exe_Url_[RANDOMDATA]\[VERSION]\user.config.

To get the names:

for name in vars().keys():
  print(name)

To get the values:

for value in vars().values():
  print(value)

vars() also takes an optional argument to find out which vars are defined within an object itself.

In my case the issue was due to duplicate binding redirects in my web.config. More info here.

I assume it was because of NuGet modifying the binding redirects, but for example it was looking like this:

  <dependentAssembly>
    <assemblyIdentity name="Lucene.Net" publicKeyToken="85089178b9ac3181"/>
    <bindingRedirect oldVersion="0.0.0.0-2.9.4.0" newVersion="3.0.3.0"/>
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed"/>
    <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0"/>
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
    <bindingRedirect oldVersion="0.0.0.0-4.2.0.0" newVersion="4.0.0.0"/>
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="Lucene.Net" publicKeyToken="85089178b9ac3181"/>
    <bindingRedirect oldVersion="0.0.0.0-2.9.4.0" newVersion="3.0.3.0"/>
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed"/>
    <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0"/>
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
    <bindingRedirect oldVersion="0.0.0.0-4.2.0.0" newVersion="4.0.0.0"/>
  </dependentAssembly>

Removing all the duplicates solved the problem.

This error also comes if 2 versions of hamcrest-library or hamcrest-core is present in the classpath.

In the pom file, you can exclude the extra version and it works.

You could also add the external jar file to the project. Go to your project-->properties-->java build path-->libraries, add external JARS. Then add your downloaded jar file.

First of all, there are still browsers out there that don't support those pseudo-elements (ie. :first-child, :last-child), so you have to 'deal' with this issue.

There is a good example how to make that work without using pseudo-elements:

http://www.darowski.com/tracesofinspiration/2010/01/11/this-newbies-first-impressions-of-haml-and-sass/

       -- see the divider pipe example.

I hope that was useful.

Another Ionic way. Using this ion-buttons tag, and the right keyword puts all the buttons in this group to the right. I made some custom toggle buttons that i wanted on one line, but the group to be right justified.

<ion-buttons right>_x000D_
<button ....>1</button>_x000D_
<button ....>2</button>_x000D_
<button ....>3</button>_x000D_
</ion-buttons>

I was getting this error : javax.faces.application.ViewExpiredException.When I using different requests, I found those having same JsessionId, even after restarting the server. So this is due to the browser cache. Just close the browser and try, it will work.

The IHttpContextAccessor method does work if you wish to go this route.

TLDR;

• Inject the IHttpContextAccessor

• Rewind -- HttpContextAccessor.HttpContext.Request.Body.Seek(0, System.IO.SeekOrigin.Begin);

• Read -- System.IO.StreamReader sr = new System.IO.StreamReader(HttpContextAccessor.HttpContext.Request.Body); JObject asObj = JObject.Parse(sr.ReadToEnd());

More -- An attempt at a concise, non-compiling, example of the items you'll need to ensure are in place in order to get at a useable IHttpContextAccessor. Answers have pointed out correctly that you'll need to seek back to the start when you try to read the request body. The CanSeek, Position properties on the request body stream helpful for verifying this.

.NET Core DI Docs

// First -- Make the accessor DI available
//
// Add an IHttpContextAccessor to your ConfigureServices method, found by default
// in your Startup.cs file:
// Extraneous junk removed for some brevity:
public void ConfigureServices(IServiceCollection services)
{
    // Typical items found in ConfigureServices:
    services.AddMvc(config => { config.Filters.Add(typeof(ExceptionFilterAttribute)); });
    // ...

    // Add or ensure that an IHttpContextAccessor is available within your Dependency Injection container
    services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}

// Second -- Inject the accessor
//
// Elsewhere in the constructor of a class in which you want
// to access the incoming Http request, typically 
// in a controller class of yours:
public class MyResourceController : Controller
{
    public ILogger<PricesController> Logger { get; }
    public IHttpContextAccessor HttpContextAccessor { get; }

    public CommandController(
        ILogger<CommandController> logger,
        IHttpContextAccessor httpContextAccessor)
    {
        Logger = logger;
        HttpContextAccessor = httpContextAccessor;
    }

    // ...

    // Lastly -- a typical use 
    [Route("command/resource-a/{id}")]
    [HttpPut]
    public ObjectResult PutUpdate([FromRoute] string id, [FromBody] ModelObject requestModel)
    {
        if (HttpContextAccessor.HttpContext.Request.Body.CanSeek)
        {
            HttpContextAccessor.HttpContext.Request.Body.Seek(0, System.IO.SeekOrigin.Begin);
            System.IO.StreamReader sr = new System.IO.StreamReader(HttpContextAccessor.HttpContext.Request.Body);
            JObject asObj = JObject.Parse(sr.ReadToEnd());

            var keyVal = asObj.ContainsKey("key-a");
        }
    }
}

static_cast checks at compile time that conversion is not between obviously incompatible types. Contrary to dynamic_cast, no check for types compatibility is done at run time. Also, static_cast conversion is not necessarily safe.

static_cast is used to convert from pointer to base class to pointer to derived class, or between native types, such as enum to int or float to int.

The user of static_cast must make sure that the conversion is safe.

The C-style cast does not perform any check, either at compile or at run time.

I can offer you some general algorithms...

• O(1): Accessing an element in an array (i.e. int i = a[9])
• O(n log n): quick or mergesort (On average)
• O(log n): Binary search

These would be the gut responses as this sounds like homework/interview kind of question. If you are looking for something more concrete it's a little harder as the public in general would have no idea of the underlying implementation (Sparing open source of course) of a popular application, nor does the concept in general apply to an "application"

There are several options. You can use the WebMethod attribute, for your purpose.

Below is my code for fetch. Took me while researching because jQuery.active doesn't work with fetch. Here is the answer helped me proxy fetch, but its only for ajax not fetch mock for selenium

easy and neat(assuming contents in the file are less than 10000):

void read_whole_file(char fileName[1000], char buffer[10000])
{
    FILE * file = fopen(fileName, "r");
    if(file == NULL)
    {
        puts("File not found");
        exit(1);
    }
    char  c;
    int idx=0;
    while (fscanf(file , "%c" ,&c) == 1)
    {
        buffer[idx] = c;
        idx++;
    }
    buffer[idx] = 0;
}

This is an implementation of aforementioned StanLe's anwer, also fixing the case where his answer would produce no curve when using densities.

This replaces the existing but hidden hist.default() function, to only add the normalcurve parameter (which defaults to TRUE).

The first three lines are to support roxygen2 for package building.

#' @noRd
#' @exportMethod hist.default
#' @export
hist.default <- function(x,
                         breaks = "Sturges",
                         freq = NULL,
                         include.lowest = TRUE,
                         normalcurve = TRUE,
                         right = TRUE,

Quick example:

hist(g)

For dates it's bit different. For reference:

#' @noRd
#' @exportMethod hist.Date
#' @export
hist.Date <- function(x,
                      breaks = "months",
                      format = "%b",
                      normalcurve = TRUE,
                      xlab = xname,
                      plot = TRUE,
                      freq = NULL,
                      density = NULL,
                      start.on.monday = TRUE,
                      right = TRUE,
                      ...)  {

  # https://stackoverflow.com/a/20078645/4575331

    )
  )

  if (normalcurve == TRUE & plot == TRUE) {
    x <- x[!is.na(x)]
    xfit <- seq(min(x), max(x), length = 40)
    yfit <- dnorm(xfit, mean = mean(x), sd = sd(x))
    if (isTRUE(freq) | (is.null(freq) & is.null(density))) {
      yfit <- as.double(yfit) * diff(h$mids[1:2]) * length(x)
    }
    lines(xfit, yfit, col = "black", lwd = 2)
  }

  if (plot == TRUE) {
    invisible(h)
  } else {
    h
  }
}

The dataset:

dat <- read.table(text = "A   B   C   D   E   F    G
1 480 780 431 295 670 360  190
2 720 350 377 255 340 615  345
3 460 480 179 560  60 735 1260
4 220 240 876 789 820 100   75", header = TRUE)

Now you can convert the data frame into a matrix and use the barplot function.

barplot(as.matrix(dat))

I had the following property working for me in IntelliJ 2017

  <properties>
        <java.version>1.8</java.version>       
  </properties>

I have fixed this error by running the following commands:

sudo apt remove python-pip
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

It will remove the previously installed pip and reinstall it. Thanks :)

An alternative to substr is the following, as a function:

substr_replace($string, "", -1)

Is it the fastest? I don't know, but I'm willing to bet these alternatives are all so fast that it just doesn't matter.

As far as I can see, you just added heredoc by mistake
No need to use ugly heredoc syntax here.
Just remove it and everything will work:

<p>Hello</p>
<p><?= _("World"); ?></p>

brew install ffmpeg will install what you need and all the dependencies if you are on a Mac.

nib is fine. If in doubt, refer to the Python style guide.

From PEP 8:

Package and Module Names Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

Since module names are mapped to file names, and some file systems are case insensitive and truncate long names, it is important that module names be chosen to be fairly short -- this won't be a problem on Unix, but it may be a problem when the code is transported to older Mac or Windows versions, or DOS.

When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket).

When installing a tool globally it's to be used by a user as a command line utility anywhere, including outside of node projects. Global installs for a node project are bad because they make deployment more difficult.

npm 5.2+

The npx utility bundled with npm 5.2 solves this problem. With it you can invoke locally installed utilities like globally installed utilities (but you must begin the command with npx). For example, if you want to invoke a locally installed eslint, you can do:

npx eslint .

npm < 5.2

When used in a script field of your package.json, npm searches node_modules for the tool as well as globally installed modules, so the local install is sufficient.

So, if you are happy with (in your package.json):

"devDependencies": {
    "gulp": "3.5.2"
}
"scripts": {
    "test": "gulp test"
}

etc. and running with npm run test then you shouldn't need the global install at all.

Both methods are useful for getting people set up with your project since sudo isn't needed. It also means that gulp will be updated when the version is bumped in the package.json, so everyone will be using the same version of gulp when developing with your project.

Addendum:

It appears that gulp has some unusual behaviour when used globally. When used as a global install, gulp looks for a locally installed gulp to pass control to. Therefore a gulp global install requires a gulp local install to work. The answer above still stands though. Local installs are always preferable to global installs.

It looks like there's something else called Afisho_rankimin in your DB so the function is not being created. Try calling your function something else. E.g.

CREATE FUNCTION dbo.Afisho_rankimin1(@emri_rest int)
RETURNS int
AS
   BEGIN
       Declare @rankimi int
       Select @rankimi=dbo.RESTORANTET.Rankimi
       From RESTORANTET
       Where  dbo.RESTORANTET.ID_Rest=@emri_rest
       RETURN @rankimi
  END
  GO

Note that you need to call this only once, not every time you call the function. After that try calling

SELECT dbo.Afisho_rankimin1(5) AS Rankimi 

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

Use String split method to remove :00.000

var formatedTime = currentTime.toString().split(':')
Text(formatedTime[0])

======= OR USE BELOW code for YYYY-MM-DD HH:MM:SS format without using library ====

var stringList =  DateTime.now().toIso8601String().split(new RegExp(r"[T\.]"));
var formatedDate = "${stringList[0]} ${stringList[1]}";

Since my work is used by people with non-BSD Linux as well as macOS, I've opted for using these aliases in our build scripts (sed included since it has similar issues):

##
# If you're running macOS, use homebrew to install greadlink/gsed first:
#   brew install coreutils
#
# Example use:
#   # Gets the directory of the currently running script
#   dotfilesDir=$(dirname "$(globalReadlink -fm "$0")")
#   alias al='pico ${dotfilesDir}/aliases.local'
##

function globalReadlink () {
  # Use greadlink if on macOS; otherwise use normal readlink
  if [[ $OSTYPE == darwin* ]]; then
    greadlink "$@"
  else
    readlink "$@"
  fi
}

function globalSed () {
  # Use gsed if on macOS; otherwise use normal sed
  if [[ $OSTYPE == darwin* ]]; then
    gsed "$@"
  else
    sed "$@"
  fi
}

Optional check you could add to automatically install homebrew + coreutils dependencies:

if [[ "$OSTYPE" == "darwin"* ]]; then
  # Install brew if needed
  if [ -z "$(which brew)" ]; then 
    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"; 
  fi
  # Check for coreutils
  if [ -z "$(brew ls coreutils)" ]; then
    brew install coreutils
  fi
fi

I suppose to be truly "global" it needs to check others...but that probably comes close to the 80/20 mark.

Let me present to you a glorious but terrifying hack:

import types

def _obj():
  return lambda: None

def LET(bindings, body, env=None):
  '''Introduce local bindings.
  ex: LET(('a', 1,
           'b', 2),
          lambda o: [o.a, o.b])
  gives: [1, 2]

  Bindings down the chain can depend on
  the ones above them through a lambda.
  ex: LET(('a', 1,
           'b', lambda o: o.a + 1),
          lambda o: o.b)
  gives: 2
  '''
  if len(bindings) == 0:
    return body(env)

  env = env or _obj()
  k, v = bindings[:2]
  if isinstance(v, types.FunctionType):
    v = v(env)

  setattr(env, k, v)
  return LET(bindings[2:], body, env)

You can now use this LET form as such:

map(lambda x: LET(('_', x.sort()),
                  lambda _: x[1]),
    lst)

which gives: [345, 465, 333]

This is a more complicated issue than many may think. Several browsers support built-in JavaScript location objects and associated parameters/methods accessible through window.location or document.location. However, different flavors of Internet Explorer (6,7) don't support these methods in the same way, (window.location.href? window.location.replace() not supported) so you have to access them differently by writing conditional code all the time to hand-hold Internet Explorer.

So, if you have jQuery available and loaded, you might as well use jQuery (location), as the others mentioned because it resolves these issues. If however, you are doing-for an example-some client-side geolocation redirection via JavaScript (that is, using Google Maps API and location object methods), then you may not want to load the entire jQuery library and write your conditional code that checks every version of Internet Explorer/Firefox/etc.

Internet Explorer makes the front-end coding cat unhappy, but jQuery is a plate of milk.

You can use the Description attribute to get that friendly name. You can use the code below:

public static string ToStringEnums(Enum en)
{
    Type type = en.GetType();

    MemberInfo[] memInfo = type.GetMember(en.ToString());
    if (memInfo != null && memInfo.Length > 0)
    {
        object[] attrs = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
        if (attrs != null && attrs.Length > 0)
            return ((DescriptionAttribute)attrs[0]).Description;
    }
    return en.ToString();
}

An example of when you would want to use this method: When your enum value is EncryptionProviderType and you want enumVar.Tostring() to return "Encryption Provider Type".

Prerequisite: All enum members should be applied with the attribute [Description("String to be returned by Tostring()")].

Example enum:

enum ExampleEnum
{
    [Description("One is one")]
    ValueOne = 1,
    [Description("Two is two")]
    ValueTow = 2
}

And in your class, you would use it like this:

ExampleEnum enumVar = ExampleEnum.ValueOne;
Console.WriteLine(ToStringEnums(enumVar));

Iterate through the string and make sure all the characters have a value less than 128.

Java Strings are conceptually encoded as UTF-16. In UTF-16, the ASCII character set is encoded as the values 0 - 127 and the encoding for any non ASCII character (which may consist of more than one Java char) is guaranteed not to include the numbers 0 - 127

I think you want to cast your dt to a date and fix the format of your date literal:

SELECT *
FROM table
WHERE dt::date = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

Or the standard version:

SELECT *
FROM table
WHERE CAST(dt AS DATE) = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

The extract function doesn't understand "date" and it returns a number.

Nothing I tried above worked for me (not that I tried every suggestion). What finally did the trick was to rename the class -- I just added a 2 to the class name and filename. Then I resolved all the references manually. (Since they weren't recognized, the refactoring did not change the references automatically.)

Once the "2-version" was happily resolved everywhere, I was then able to refactor and remove the 2 from the class and file, and everything was then as it should be.

You can set a default style for the entire workbook (all worksheets):

$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getTop()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getBottom()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getLeft()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getRight()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

or

  $styleArray = array(
      'borders' => array(
          'allborders' => array(
              'style' => PHPExcel_Style_Border::BORDER_THIN
          )
      )
  );
$objPHPExcel->getDefaultStyle()->applyFromArray($styleArray);

And this can be used for all style properties, not just borders.

But column autosizing is structural rather than stylistic, and has to be set for each column on each worksheet individually.

EDIT

Note that default workbook style only applies to Excel5 Writer

Your PHP script (external file 'email.php') should look like this:

<?php
if($_POST){
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['text'];

//send email
    mail("[email protected]", "51 Deep comment from" .$email, $message);
}
?>

Your question shows you have succumbed to some of the common misconceptions surrounding table variables and temporary tables.

I have written quite an extensive answer on the DBA site looking at the differences between the two object types. This also addresses your question about disk vs memory (I didn't see any significant difference in behaviour between the two).

Regarding the question in the title though as to when to use a table variable vs a local temporary table you don't always have a choice. In functions, for example, it is only possible to use a table variable and if you need to write to the table in a child scope then only a #temp table will do (table-valued parameters allow readonly access).

Where you do have a choice some suggestions are below (though the most reliable method is to simply test both with your specific workload).

1. If you need an index that cannot be created on a table variable then you will of course need a #temporary table. The details of this are version dependant however. For SQL Server 2012 and below the only indexes that could be created on table variables were those implicitly created through a UNIQUE or PRIMARY KEY constraint. SQL Server 2014 introduced inline index syntax for a subset of the options available in CREATE INDEX. This has been extended since to allow filtered index conditions. Indexes with INCLUDE-d columns or columnstore indexes are still not possible to create on table variables however.

2. If you will be repeatedly adding and deleting large numbers of rows from the table then use a #temporary table. That supports TRUNCATE (which is more efficient than DELETE for large tables) and additionally subsequent inserts following a TRUNCATE can have better performance than those following a DELETE as illustrated here.

3. If you will be deleting or updating a large number of rows then the temp table may well perform much better than a table variable - if it is able to use rowset sharing (see "Effects of rowset sharing" below for an example).
4. If the optimal plan using the table will vary dependent on data then use a #temporary table. That supports creation of statistics which allows the plan to be dynamically recompiled according to the data (though for cached temporary tables in stored procedures the recompilation behaviour needs to be understood separately).
5. If the optimal plan for the query using the table is unlikely to ever change then you may consider a table variable to skip the overhead of statistics creation and recompiles (would possibly require hints to fix the plan you want).
6. If the source for the data inserted to the table is from a potentially expensive SELECT statement then consider that using a table variable will block the possibility of this using a parallel plan.
7. If you need the data in the table to survive a rollback of an outer user transaction then use a table variable. A possible use case for this might be logging the progress of different steps in a long SQL batch.
8. When using a #temp table within a user transaction locks can be held longer than for table variables (potentially until the end of transaction vs end of statement dependent on the type of lock and isolation level) and also it can prevent truncation of the tempdb transaction log until the user transaction ends. So this might favour the use of table variables.
9. Within stored routines, both table variables and temporary tables can be cached. The metadata maintenance for cached table variables is less than that for #temporary tables. Bob Ward points out in his tempdb presentation that this can cause additional contention on system tables under conditions of high concurrency. Additionally, when dealing with small quantities of data this can make a measurable difference to performance.

os.stat https://docs.python.org/2/library/stat.html#module-stat

edit: In newer code you should probably use os.path.getmtime() (thanks Christian Oudard)
but note that it returns a floating point value of time_t with fraction seconds (if your OS supports it)

This should work for you

You can use any delimiter as field separator and can find numbers of ROWS and columns

If you want to use timeit in an interactive Python session, there are two convenient options:

1. Use the IPython shell. It features the convenient %timeit special function:

   In [1]: def f(x):
      ...:     return x*x
      ...: 
   
   In [2]: %timeit for x in range(100): f(x)
   100000 loops, best of 3: 20.3 us per loop
   

2. In a standard Python interpreter, you can access functions and other names you defined earlier during the interactive session by importing them from __main__ in the setup statement:

   >>> def f(x):
   ...     return x * x 
   ... 
   >>> import timeit
   >>> timeit.repeat("for x in range(100): f(x)", "from __main__ import f",
                     number=100000)
   [2.0640320777893066, 2.0876040458679199, 2.0520210266113281]
   

Give something like this a try:

$(document).ready(function(){
    $("#thisTable tr").click(function(){
        $(this).find("td").each(function(){
            alert($(this).html());
        });
    });
});?

Here is a fiddle of the code in action: http://jsfiddle.net/YhZsW/

Unfortunately, there doesn't seem to be a period class that spans time as well, so you might have to do the calculations on your own.

Fortunately, the date and time classes have a lot of utility methods that simplify that to some degree. Here's a way to calculate the difference although not necessarily the fastest:

LocalDateTime fromDateTime = LocalDateTime.of(1984, 12, 16, 7, 45, 55);
LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 10, 6, 40, 45);

LocalDateTime tempDateTime = LocalDateTime.from( fromDateTime );

long years = tempDateTime.until( toDateTime, ChronoUnit.YEARS );
tempDateTime = tempDateTime.plusYears( years );

long months = tempDateTime.until( toDateTime, ChronoUnit.MONTHS );
tempDateTime = tempDateTime.plusMonths( months );

long days = tempDateTime.until( toDateTime, ChronoUnit.DAYS );
tempDateTime = tempDateTime.plusDays( days );


long hours = tempDateTime.until( toDateTime, ChronoUnit.HOURS );
tempDateTime = tempDateTime.plusHours( hours );

long minutes = tempDateTime.until( toDateTime, ChronoUnit.MINUTES );
tempDateTime = tempDateTime.plusMinutes( minutes );

long seconds = tempDateTime.until( toDateTime, ChronoUnit.SECONDS );

System.out.println( years + " years " + 
        months + " months " + 
        days + " days " +
        hours + " hours " +
        minutes + " minutes " +
        seconds + " seconds.");

//prints: 29 years 8 months 24 days 22 hours 54 minutes 50 seconds.

The basic idea is this: create a temporary start date and get the full years to the end. Then adjust that date by the number of years so that the start date is less then a year from the end. Repeat that for each time unit in descending order.

Finally a disclaimer: I didn't take different timezones into account (both dates should be in the same timezone) and I also didn't test/check how daylight saving time or other changes in a calendar (like the timezone changes in Samoa) affect this calculation. So use with care.

Null OR an empty string?

if (!empty($user)) {}

Use empty().

After realizing that $user ~= $_POST['user'] (thanks matt):

var uservariable='<?php 
    echo ((array_key_exists('user',$_POST)) || (!empty($_POST['user']))) ? $_POST['user'] : 'Empty Username Input';
?>';

It's too late but hope it helps. Most of the answers are not pointing into the right direction. There are two simple flags for such thing.

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

From Android docs:

public static final int FLAG_ACTIVITY_CLEAR_TASK Added in API level 11

If set in an Intent passed to Context.startActivity(), this flag will cause any existing task that would be associated with the

activity to be cleared before the activity is started. That is, the activity becomes the new root of an otherwise empty task, and any old activities are finished. This can only be used in conjunction with FLAG_ACTIVITY_NEW_TASK.

I got a bit annoyed with reading that multiline syntax is indeed been planned for jdk7 (after about how many decades of java existence?). Funnily, there is not even yet a readAll() function for reading the complete contents of a file (from jdk7 only, huhh), so the code below reads single lines.

/*

  Useful for working around missing multiline string syntax in java

import java.io.*;

class MakeMultiline {
  public static void main(String[] args) {
    try {
      // args[0]: indent
      // args[1]: filename to read (optional; stdin if not given)
      // Beware the nmb of newlines at the end when using stdin!

      String indent = (args.length > 0 ? args[0] : "");
      FileReader fr = null; BufferedReader br;
      if (args.length > 1)
        { fr =  new FileReader(args[1]); br = new BufferedReader(fr); }
      else
        { br = new BufferedReader(new InputStreamReader(System.in)); }
      String s; String res = "";
      while((s = br.readLine()) != null) {
        if (res.length() > 0) res += " +\n";
        res += indent + "\"" + s.replace("\"", "\\\"") + "\\n\"";
      }
      br.close(); if (fr != null) fr.close();
      System.out.println(res + ";");
    }
    catch(Exception e) {
      System.out.println("Exception: " + e);
    }
  }
}

This was the quickest solution for me. (2010-01-27)

Make sure you are loading those modules (myApp.services and myApp.directives) as dependencies of your main app module, like this:

angular.module('myApp', ['myApp.directives', 'myApp.services']);

This example selects a new Range of Cells defined by the current cell to a cell 5 to the right.

Note that .Offset takes arguments of Offset(row, columns) and can be quite useful.

End Sub

The javax.naming package comprises the JNDI API. Since it's just an API, rather than an implementation, you need to tell it which implementation of JNDI to use. The implementations are typically specific to the server you're trying to talk to.

To specify an implementation, you pass in a Properties object when you construct the InitialContext. These properties specify the implementation to use, as well as the location of the server. The default InitialContext constructor is only useful when there are system properties present, but the properties are the same as if you passed them in manually.

As to which properties you need to set, that depends on your server. You need to hunt those settings down and plug them in.

Do you mean like this

int index = 2;
string s = "hello";
Console.WriteLine(s[index]);

string also implements IEnumberable<char> so you can also enumerate it like this

foreach (char c in s)
    Console.WriteLine(c);

Note that since git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1 and release note, June 2012) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

recurse-submodules=<check|on-demand>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

So you could push everything in one go with (from the parent repo) a:

git push --recurse-submodules=on-demand

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

With git 2.7 (January 2016), a simple git push will be enough to push the parent repo... and all its submodules.

See commit d34141c, commit f5c7cd9 (03 Dec 2015), commit f5c7cd9 (03 Dec 2015), and commit b33a15b (17 Nov 2015) by Mike Crowe (mikecrowe).
^{(Merged by Junio C Hamano -- gitster -- in commit 5d35d72, 21 Dec 2015)}

push: add recurseSubmodules config option

The --recurse-submodules command line parameter has existed for some time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's invent push.recurseSubmodules to provide a default for this parameter.
This also requires the addition of --recurse-submodules=no to allow the configuration to be overridden on the command line when required.

The most straightforward way to implement this appears to be to make push use code in submodule-config in a similar way to fetch.

The git config doc now include:

push.recurseSubmodules:

Make sure all submodule commits used by the revisions to be pushed are available on a remote-tracking branch.

• If the value is 'check', then Git will verify that all submodule commits that changed in the revisions to be pushed are available on at least one remote of the submodule. If any commits are missing, the push will be aborted and exit with non-zero status.
• If the value is 'on-demand' then all submodules that changed in the revisions to be pushed will be pushed. If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status. -
• If the value is 'no' then default behavior of ignoring submodules when pushing is retained.

You may override this configuration at time of push by specifying '--recurse-submodules=check|on-demand|no'.

So:

git config push.recurseSubmodules on-demand
git push

Git 2.12 (Q1 2017)

git push --dry-run --recurse-submodules=on-demand will actually work.

See commit 0301c82, commit 1aa7365 (17 Nov 2016) by Brandon Williams (mbrandonw).
^{(Merged by Junio C Hamano -- gitster -- in commit 12cf113, 16 Dec 2016)}

push run with --dry-run doesn't actually (Git 2.11 Dec. 2016 and lower/before) perform a dry-run when push is configured to push submodules on-demand.
Instead all submodules which need to be pushed are actually pushed to their remotes while any updates for the superproject are performed as a dry-run.
This is a bug and not the intended behaviour of a dry-run.

Teach push to respect the --dry-run option when configured to recursively push submodules 'on-demand'.
This is done by passing the --dry-run flag to the child process which performs a push for a submodules when performing a dry-run.

And still in Git 2.12, you now havea "--recurse-submodules=only" option to push submodules out without pushing the top-level superproject.

See commit 225e8bf, commit 6c656c3, commit 14c01bd (19 Dec 2016) by Brandon Williams (mbrandonw).
^{(Merged by Junio C Hamano -- gitster -- in commit 792e22e, 31 Jan 2017)}

A new library called ts-optchain provides this functionality, and unlike lodash' solution, it also keeps your types safe, here is a sample of how it is used (taken from the readme):

import { oc } from 'ts-optchain';

interface I {
  a?: string;
  b?: {
    d?: string;
  };
  c?: Array<{
    u?: {
      v?: number;
    };
  }>;
  e?: {
    f?: string;
    g?: () => string;
  };
}

const x: I = {
  a: 'hello',
  b: {
    d: 'world',
  },
  c: [{ u: { v: -100 } }, { u: { v: 200 } }, {}, { u: { v: -300 } }],
};

// Here are a few examples of deep object traversal using (a) optional chaining vs
// (b) logic expressions. Each of the following pairs are equivalent in
// result. Note how the benefits of optional chaining accrue with
// the depth and complexity of the traversal.

oc(x).a(); // 'hello'
x.a;

oc(x).b.d(); // 'world'
x.b && x.b.d;

oc(x).c[0].u.v(); // -100
x.c && x.c[0] && x.c[0].u && x.c[0].u.v;

oc(x).c[100].u.v(); // undefined
x.c && x.c[100] && x.c[100].u && x.c[100].u.v;

oc(x).c[100].u.v(1234); // 1234
(x.c && x.c[100] && x.c[100].u && x.c[100].u.v) || 1234;

oc(x).e.f(); // undefined
x.e && x.e.f;

oc(x).e.f('optional default value'); // 'optional default value'
(x.e && x.e.f) || 'optional default value';

// NOTE: working with function value types can be risky. Additional run-time
// checks to verify that object types are functions before invocation are advised!
oc(x).e.g(() => 'Yo Yo')(); // 'Yo Yo'
((x.e && x.e.g) || (() => 'Yo Yo'))();

Really strange: This question is active for five years now and there is still no vanilla JavaScript answer to animate the scrolling… So here you go:

var scrollToTop = window.setInterval(function() {
    var pos = window.pageYOffset;
    if ( pos > 0 ) {
        window.scrollTo( 0, pos - 20 ); // how far to scroll on each step
    } else {
        window.clearInterval( scrollToTop );
    }
}, 16); // how fast to scroll (this equals roughly 60 fps)

If you like, you can wrap this in a function and call that via the onclick attribute. Check this jsfiddle

Note: This is a very basic solution and maybe not the most performant one. A very elaborated example can be found here: https://github.com/cferdinandi/smooth-scroll

Just use Double.compare() method to compare double values.
Double.compare((d1,d2) == 0)

double d1 = 0.0;
double d2 = 0.0;

System.out.println(Double.compare((d1,d2) == 0))  // true

Try using a return statement. It works best. It stops the function when the condition is met.

function anything() {
    var get = document.getElementsByClassName("text ").value;
    if (get == null) {
        alert("Please put in your name");
    }

    return;

    var random = Math.floor(Math.random() * 100) + 1;
    console.log(random);
}

There was auto generated Copyright message in XML and a blank line before <resources> tag, once I removed it my build was successful.

Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.

$products = DB::table('products AS pr')
        ->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
        ->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
        ->orderBy('pr.id', 'desc')
        ->get();

Hope this helps.

You can use the event ProgressChanged ; the last time it is raised will indicate that the document is fully rendered:

this.webBrowser.ProgressChanged += new
WebBrowserProgressChangedEventHandler(webBrowser_ProgressChanged);

I had this issue and found that the problem was that I had not registered the JacksonFeature class:

// Create JAX-RS application.
final Application application = new ResourceConfig()
    ...
    .register(JacksonFeature.class);

Without doing this your application does not know how to convert the JSON to a java object.

https://jersey.java.net/documentation/latest/media.html#json.jackson

You can use set with the /p argument:

SET /P variable=[promptString]

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

So, simply use something like

set /p Input=Enter some text: 

Later you can use that variable as argument to a command:

myCommand %Input%

Be careful though, that if your input might contain spaces it's probably a good idea to quote it:

myCommand "%Input%"

Just create a new array in your dictionary

Dictionary<string, List<string>> myDic = new Dictionary<string, List<string>>();
myDic.Add(newKey, new List<string>(existingList));

If the compiler can do automatic type inferencing, then there wont be any issue with performance. Both of these will generate same code

var    x = new ClassA();
ClassA x = new ClassA();

however, if you are constructing the type dynamically (LINQ ...) then var is your only question and there is other mechanism to compare to in order to say what is the penalty.

On iOS 5 UIEdgeInsetsMake(-8,-8,-8,-8); seems to work great.

Expanding upon Melu's answer you can do this to functionalize the code and handle negative amounts.

Sample Output:
$5.23
-$5.23

function formatCurrency(total) {
    var neg = false;
    if(total < 0) {
        neg = true;
        total = Math.abs(total);
    }
    return (neg ? "-$" : '$') + parseFloat(total, 10).toFixed(2).replace(/(\d)(?=(\d{3})+\.)/g, "$1,").toString();
}

The result is probably not in JSON format, so when jQuery tries to parse it as such, it fails. You can catch the error with error: callback function.

You don't seem to need JSON in that function anyways, so you can also take out the dataType: 'json' row.

May be you want this (oop in javascript)

function box(color)
{
    this.color=color;
}

var box1=new box('red');    
var box2=new box('white');

Opening a file in "write" mode clears it, you don't specifically have to write to it:

open("filename", "w").close()

(you should close it as the timing of when the file gets closed automatically may be implementation specific)

WebBrowser1.Document.GetElementById(*element id string*).InvokeMember("submit")

There's a special function n() in dplyr to count rows (potentially within groups):

library(dplyr)
mtcars %>% 
  group_by(cyl, gear) %>% 
  summarise(n = n())
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

But dplyr also offers a handy count function which does exactly the same with less typing:

count(mtcars, cyl, gear)          # or mtcars %>% count(cyl, gear)
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

As an aside, it is always a good practice (and possibly a solution for this type of issue) to delete a large number of rows by using batches:

WHILE EXISTS (SELECT 1 
              FROM   YourTable 
              WHERE  <yourCondition>) 
  DELETE TOP(10000) FROM YourTable 
  WHERE  <yourCondition>

For cross-platform support, make the command separator (for executing multiple commands on the same line) configurable.

If you're using MinGW on a Windows platform for example, the command separator is &:

NUMBERS = 1 2 3 4
CMDSEP = &
doit:
    $(foreach number,$(NUMBERS),./a.out $(number) $(CMDSEP))

This executes the concatenated commands in one line:

./a.out 1 & ./a.out 2 & ./a.out 3 & ./a.out 4 &

As mentioned elsewhere, on a *nix platform use CMDSEP = ;.

Answers provided here as which camera api to use are wrong. Or better to say they are insufficient.

Some phones (for example Samsung Galaxy S6) could be above api level 21 but still may not support Camera2 api.

CameraCharacteristics mCameraCharacteristics = mCameraManager.getCameraCharacteristics(mCameraId);
Integer level = mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);
if (level == null || level == CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY) {
    return false;
}

CameraManager class in Camera2Api has a method to read camera characteristics. You should check if hardware wise device is supporting Camera2 Api or not.

But there are more issues to handle if you really want to make it work for a serious application: Like, auto-flash option may not work for some devices or battery level of the phone might create a RuntimeException on Camera or phone could return an invalid camera id and etc.

So best approach is to have a fallback mechanism as for some reason Camera2 fails to start you can try Camera1 and if this fails as well you can make a call to Android to open default Camera for you.

try to change the value sharply and then assign the $scope

document.getElementById ("textWidget") value = "<NewVal>";
$scope.widget.title = "<NewVal>";

Dear You have used two Intent launcher in your Manifest. Make only one Activity as launcher: Your manifest activity is :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.th.mybook"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="8" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".MainTabPanel"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />

and Second error may be if you copy paste old code then please update com.example.packagename.FILE_NAME

hope this will work !

On windows you can use a graphic interface of scp using winSCP. A nice free software that implements SFTP protocol.

This is an option:

dbContext.Entry(entity).State = EntityState.Detached;

Nowadays at least with android it's relatively easy. Just use normal file input tag and when user clicks it the phone will ask if user wants to use camera (or file managers etc..) to upload a file. Just take a photo with the camera and it will automatically be added and uploaded.

No idea about iphone. Maybe someone can enlighten on that. EDIT: Iphone works similarly.

Sample of the input tag:

<input type="file" accept="image/*" capture="camera">

It sounds like the answer is no :). I don't really want to create an alias or func just to do this, often because it's one-off and I'm already in the middle of typing the mv command, but I found something that works well for that:

mv *.sh  shell_files/also_with_subdir/ || mkdir -p $_

If mv fails (dir does not exist), it will make the directory (which is the last argument to the previous command, so $_ has it). So just run this command, then up to re-run it, and this time mv should succeed.

I got the same issue and this solved it for me. Perhaps this might be a fix for your problem too.

Here is the fix. Follow this link http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Go to "Fixed curl extensions" and download the extension that matches your PHP version.

Extract and copy "php_curl.dll" to the extension directory of your wamp installation. (i.e. C:\wamp\bin\php\php5.3.13\ext)

Restart Apache

Done!

Refer to: http://blog.nterms.com/2012/07/php-curl-issues-with-wamp-server-on.html

Cheers!

try this:

struct Pos{
    int x;
    int y;

    inline Pos& operator=(const Pos& other){
        x=other.x;
        y=other.y;
        return *this;
    }

    inline Pos operator+(const Pos& other) const {
        Pos res {x+other.x,y+other.y};
        return res;
    }

    const inline bool operator==(const Pos& other) const {
        return (x==other.x and y == other.y);
    }
 };  

strtok doesn't change the parameter itself (str). It stores that pointer (in a local static variable). It can then change what that parameter points to in subsequent calls without having the parameter passed back. (And it can advance that pointer it has kept however it needs to perform its operations.)

From the POSIX strtok page:

This function uses static storage to keep track of the current string position between calls.

There is a thread-safe variant (strtok_r) that doesn't do this type of magic.

Firstly, it probably depends which version of Solaris you're running, but also what hardware you have.

On SPARC at least, you have psrinfo to show you processor information, which run on its own will show you the number of CPUs the machine sees. psrinfo -p shows you the number of physical processors installed. From that you can deduce the number of threads/cores per physical processors.

prtdiag will display a fair bit of info about the hardware in your machine. It looks like on a V240 you do get memory channel info from prtdiag, but you don't on a T2000. I guess that's an architecture issue between UltraSPARC IIIi and UltraSPARC T1.

another solution is the function you can embed into your own utils.py

import time as time_ #make sure we don't override time
def millis():
    return int(round(time_.time() * 1000))

If your email address is '[email protected]', try changing the createDirectoryEntry() as below.

XYZ is an optional parameter if it exists in mydomain directory

static DirectoryEntry createDirectoryEntry()
{
    // create and return new LDAP connection with desired settings
    DirectoryEntry ldapConnection = new DirectoryEntry("myname.mydomain.com");
    ldapConnection.Path = "LDAP://OU=Users, OU=XYZ,DC=mydomain,DC=com";
    ldapConnection.AuthenticationType = AuthenticationTypes.Secure;
    return ldapConnection;
}

This will basically check for com -> mydomain -> XYZ -> Users -> abcd

The main function looks as below:

try
{
    username = "Firstname LastName"
    DirectoryEntry myLdapConnection = createDirectoryEntry();
    DirectorySearcher search = new DirectorySearcher(myLdapConnection);
    search.Filter = "(cn=" + username + ")";
    ....    

Simple read loop use this code

var resx = ResourcesName.ResourceManager.GetResourceSet(CultureInfo.CurrentUICulture, false, false);

foreach (DictionaryEntry dictionaryEntry in resx)
{
    Console.WriteLine("Key: " + dictionaryEntry.Key);
    Console.WriteLine("Val: " + dictionaryEntry.Value);
}

If you want make a border in a shape xml. You need to use:

For the external border,you need to use:

<stroke/>

For the internal background,you need to use:

<solid/>

If you want to set corners,you need to use:

<corners/>

If you want a padding betwen border and the internal elements,you need to use:

<padding/>

Here is a shape xml example using the above items. It works for me

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="2dp" android:color="#D0CFCC" /> 
  <solid android:color="#F8F7F5" /> 
  <corners android:radius="10dp" />
  <padding android:left="2dp" android:top="2dp" android:right="2dp" android:bottom="2dp" />
</shape>

you cannot call a controller method from another controller directly

my solution is to use inheritances and extend your controller from the library controller

class Controller1 extends CI_Controller {

    public function index() {
        // some codes here
    }

    public function methodA(){
        // code here
    }
}

in your controller we call it Mycontoller it will extends Controller1

include_once (dirname(__FILE__) . "/controller1.php");

class Mycontroller extends Controller1 {

    public function __construct() {
        parent::__construct();
    }

    public function methodB(){
        // codes....
    }
}

and you can call methodA from mycontroller

http://example.com/mycontroller/methodA

http://example.com/mycontroller/methodB

this solution worked for me

That is the mode with which you are opening the file. "wb" means that you are writing to the file (w), and that you are writing in binary mode (b).

Check out the documentation for more: clicky

Easiest solution is to use BuildConfig.

I use BuildConfig.VERSION_NAME in my application.

You can also use BuildConfig.VERSION_CODE to get version code.

Remove the FormsModule from Declaration:[] and Add the FormsModule in imports:[]

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})

Suppose for some reason Ctrl+Z is also not working, go to another terminal, find the process id (using ps) and run:

kill -SIGSTOP PID 
kill -SIGCONT PID

SIGSTOP will suspend the process and SIGCONT will resume the process, in background. So now, closing both your terminals won't stop your process.

Here's pure javascript example of handling classes during scrolling.

You'd probably want to throttle handling scroll events, more so as handler logic gets more complex, in that case throttle from lodash lib comes in handy.

And if you're doing spa, keep in mind that you need to clear event listeners with removeEventListener once they're not needed (eg during onDestroy lifecycle hook of your component, like destroyed() for Vue, or maybe return function of useEffect hook for React).

const navbar = document.getElementById('navbar')_x000D_
_x000D_
// OnScroll event handler_x000D_
const onScroll = () => {_x000D_
_x000D_
  // Get scroll value_x000D_
  const scroll = document.documentElement.scrollTop_x000D_
_x000D_
  // If scroll value is more than 0 - add class_x000D_
  if (scroll > 0) {_x000D_
    navbar.classList.add("scrolled");_x000D_
  } else {_x000D_
    navbar.classList.remove("scrolled")_x000D_
  }_x000D_
}_x000D_
_x000D_
// Optional - throttling onScroll handler at 100ms with lodash_x000D_
const throttledOnScroll = _.throttle(onScroll, 100, {})_x000D_
_x000D_
// Use either onScroll or throttledOnScroll_x000D_
window.addEventListener('scroll', onScroll)

#navbar {_x000D_
  position: fixed;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  right: 0;_x000D_
  width: 100%;_x000D_
  height: 60px;_x000D_
  background-color: #89d0f7;_x000D_
  box-shadow: 0px 5px 0px rgba(0, 0, 0, 0);_x000D_
  transition: box-shadow 500ms;_x000D_
}_x000D_
_x000D_
#navbar.scrolled {_x000D_
  box-shadow: 0px 5px 10px rgba(0, 0, 0, 0.25);_x000D_
}_x000D_
_x000D_
#content {_x000D_
  height: 3000px;_x000D_
  margin-top: 60px;_x000D_
}

<!-- Optional - lodash library, used for throttlin onScroll handler-->_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.15/lodash.js"></script>_x000D_
<header id="navbar"></header>_x000D_
<div id="content"></div>

You can use this simple ES6 method

const lastChar = (str) => str.split('').reverse().join(',').replace(',', '')[str.length === str.length + 1 ? 1 : 0];_x000D_
_x000D_
_x000D_
// example_x000D_
console.log(lastChar("linto.yahoo.com."));

This will work in every browsers.

I tried replacing value with Value and it worked out. It has set the value in input tag now.

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

Hey all this is ridiculously easy...

1. Create a new branch from your first commit
2. When you want to find out your stats, create a new PR from main
3. The PR will show you the number of changed lines - as you're doing a PR from the first commit all your code will be counted as new lines

And the added benefit is that if you don't approve the PR and just leave it in place, the stats (No of commits, files changed and total lines of code) will simply keep up-to-date as you merge changes into main. :) Enjoy.

Files related for deployment (and others temporary items) are created in standalone/tmp/vfs (Virtual File System). You may add a policy at startup for evicting temporary files :

-Djboss.vfs.cache=org.jboss.virtual.plugins.cache.IterableTimedVFSCache 
-Djboss.vfs.cache.TimedPolicyCaching.lifetime=1440

try this :

SET @StartDate = DATE_SUB(DATE(NOW()),INTERVAL (DAY(NOW())-1) DAY);
SET @EndDate = ADDDATE(CURDATE(),1);
select * from table where (date >= @StartDate and date < @EndDate);

npm install installs all modules that are listed on package.json file and their dependencies.

npm update updates all packages in the node_modules directory and their dependencies.

npm install express installs only the express module and its dependencies.

npm update express updates express module (starting with [email protected], it doesn't update its dependencies).

So updates are for when you already have the module and wish to get the new version.

A parser from int variables to the long type is included in the Integer class. Here is an example:

int n=10;
long n_long=Integer.toUnsignedLong(n);

You can easily use this in-built function to create a method that parses from int to long:

    public static long toLong(int i){
    long l;
    if (i<0){
        l=-Integer.toUnsignedLong(Math.abs(i));
    }
    else{
        l=Integer.toUnsignedLong(i);
    }
    return l;
}

To keep jQuery and the DOM in sync, a simple option may be

$('#mydiv').data('myval',20).attr('data-myval',20);        

In my case, I needed to set QUOTED_IDENTIFIER on. This led to a slight modification of Mark Rendle's answer above:

EXEC sp_MSForEachTable 'DISABLE TRIGGER ALL ON ?'
GO
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO
EXEC sp_MSForEachTable 'SET QUOTED_IDENTIFIER ON; DELETE FROM ?'
GO
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
GO

Even though the <head> and <body> tags aren't required, the elements are still there - it's just that the browser can work out where the tags would have been from the rest of the document.

The other elements you're using still have to be inside the <body>

Reinstalling python based on instructions from here solved this problem for me: How can I install a previous version of Python 3 in macOS using homebrew?

FOR MAC USERS if you are working with open cv

import cv2

cv2.imwrite('path_to_folder/image.jpg',image)

If you are using MySQL you can do it like this:

SELECT '2008-12-31 23:59:59' + INTERVAL 30 MINUTE;

For a pure PHP solution use strtotime

strtotime('+ 30 minute',$yourdate);

Here is another version if you have to reference a specific docker file:

version: "3"
services:
  nginx:
    container_name: nginx
    build:
      context: ../..
      dockerfile: ./docker/nginx/Dockerfile
    image: my_nginx:latest

Then you just run

docker-compose build

.aspx uses a full lifecycle (Init, Load, PreRender) and can respond to button clicks etc.
An .ashx has just a single ProcessRequest method.

Pretty late on the answer, but if you have a TextView that you're showing the phone number in, then you don't need to deal with intents at all, you can just use the XML attribute android:autoLink="phone" and the OS will automatically initiate an ACTION_DIAL Intent.

I think that it should be:

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

Dont know, but you could perhaps check the source of one of the Firefox download addons.

Here is the source for one that I use Download Statusbar.

DECLARE @count_ser_temp int;
DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'TableTemporal'

EXECUTE ('CREATE VIEW vTemp AS
    SELECT *
    FROM ' + @TableTemporal)
SELECT TOP 1 * INTO #servicios_temp  FROM vTemp

DROP VIEW vTemp

-- Contar la cantidad de registros de la tabla temporal
SELECT @count_ser_temp = COUNT(*) FROM #servicios_temp;

-- Recorro los registros de la tabla temporal 
WHILE @count_ser_temp > 0
 BEGIN
 END
END

1- Select LinearLayout findViewById

LinearLayout llayout =(LinearLayout) findViewById(R.id.llayoutId); 

2- Set color from R.color.colorId

llayout.setBackgroundColor(getResources().getColor(R.color.colorId));

root@hostname:~# time [command]

It also distinguishes between real time used and system time used.

Swift 4 extension using explicit constraints:

import UIKit.UIView

extension UIView {
    public func addSubview(_ subview: UIView, stretchToFit: Bool = false) {
        addSubview(subview)
        if stretchToFit {
            subview.translatesAutoresizingMaskIntoConstraints = false
            leftAnchor.constraint(equalTo: subview.leftAnchor).isActive = true
            rightAnchor.constraint(equalTo: subview.rightAnchor).isActive = true
            topAnchor.constraint(equalTo: subview.topAnchor).isActive = true
            bottomAnchor.constraint(equalTo: subview.bottomAnchor).isActive = true
        }
    }
}

Usage:

parentView.addSubview(childView) // won't resize (default behavior unchanged)
parentView.addSubview(childView, stretchToFit: false) // won't resize
parentView.addSubview(childView, stretchToFit: true) // will resize

If one or both of the files you wish to compare isn't in an Eclipse project:

1. Open the Quick Access search box

   • Linux/Windows: Ctrl+3
   • Mac: ?+3

2. Type compare and select Compare With Other Resource

3. Select the files to compare ? OK

You can also create a keyboard shortcut for Compare With Other Resource by going to Window ? Preferences ? General ? Keys

A fixed point number has a specific number of bits (or digits) reserved for the integer part (the part to the left of the decimal point) and a specific number of bits reserved for the fractional part (the part to the right of the decimal point). No matter how large or small your number is, it will always use the same number of bits for each portion. For example, if your fixed point format was in decimal IIIII.FFFFF then the largest number you could represent would be 99999.99999 and the smallest non-zero number would be 00000.00001. Every bit of code that processes such numbers has to have built-in knowledge of where the decimal point is.

A floating point number does not reserve a specific number of bits for the integer part or the fractional part. Instead it reserves a certain number of bits for the number (called the mantissa or significand) and a certain number of bits to say where within that number the decimal place sits (called the exponent). So a floating point number that took up 10 digits with 2 digits reserved for the exponent might represent a largest value of 9.9999999e+50 and a smallest non-zero value of 0.0000001e-49.

If you are looking for a rapid, normalized cross correlation in either one or two dimensions I would recommend the openCV library (see http://opencv.willowgarage.com/wiki/ http://opencv.org/). The cross-correlation code maintained by this group is the fastest you will find, and it will be normalized (results between -1 and 1).

While this is a C++ library the code is maintained with CMake and has python bindings so that access to the cross correlation functions is convenient. OpenCV also plays nicely with numpy. If I wanted to compute a 2-D cross-correlation starting from numpy arrays I could do it as follows.

import numpy
import cv

#Create a random template and place it in a larger image
templateNp = numpy.random.random( (100,100) )
image = numpy.random.random( (400,400) )
image[:100, :100] = templateNp

#create a numpy array for storing result
resultNp = numpy.zeros( (301, 301) )

#convert from numpy format to openCV format
templateCv = cv.fromarray(numpy.float32(template))
imageCv = cv.fromarray(numpy.float32(image))
resultCv =  cv.fromarray(numpy.float32(resultNp))

#perform cross correlation
cv.MatchTemplate(templateCv, imageCv, resultCv, cv.CV_TM_CCORR_NORMED)

#convert result back to numpy array
resultNp = np.asarray(resultCv)

For just a 1-D cross-correlation create a 2-D array with shape equal to (N, 1 ). Though there is some extra code involved to convert to an openCV format the speed-up over scipy is quite impressive.

http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.remoteendpoint.aspx

You can then call the IPEndPoint..::.Address method to retrieve the remote IPAddress, and the IPEndPoint..::.Port method to retrieve the remote port number.

More from the link (fixed up alot heh):

Socket s;

IPEndPoint remoteIpEndPoint = s.RemoteEndPoint as IPEndPoint;
IPEndPoint localIpEndPoint = s.LocalEndPoint as IPEndPoint;

if (remoteIpEndPoint != null)
{
    // Using the RemoteEndPoint property.
    Console.WriteLine("I am connected to " + remoteIpEndPoint.Address + "on port number " + remoteIpEndPoint.Port);
}

if (localIpEndPoint != null)
{
    // Using the LocalEndPoint property.
    Console.WriteLine("My local IpAddress is :" + localIpEndPoint.Address + "I am connected on port number " + localIpEndPoint.Port);
}

You can add the command in the /etc/rc.local script that is executed at the end of startup.

Write the command before exit 0. Anything written after exit 0 will never be executed.

Weak Reference http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/ref/WeakReference.html

Principle: weak reference is related to garbage collection. Normally, object having one or more reference will not be eligible for garbage collection.
The above principle is not applicable when it is weak reference. If an object has only weak reference with other objects, then its ready for garbage collection.

Let's look at the below example: We have an Map with Objects where Key is reference a object.

import java.util.HashMap;   
public class Test {

    public static void main(String args[]) {
        HashMap<Employee, EmployeeVal> aMap = new 
                       HashMap<Employee, EmployeeVal>();

        Employee emp = new Employee("Vinoth");
        EmployeeVal val = new EmployeeVal("Programmer");

        aMap.put(emp, val);

        emp = null;

        System.gc();
        System.out.println("Size of Map" + aMap.size());

    }
}

Now, during the execution of the program we have made emp = null. The Map holding the key makes no sense here as it is null. In the above situation, the object is not garbage collected.

WeakHashMap

WeakHashMap is one where the entries (key-to-value mappings) will be removed when it is no longer possible to retrieve them from the Map.

Let me show the above example same with WeakHashMap

import java.util.WeakHashMap;

public class Test {

    public static void main(String args[]) {
        WeakHashMap<Employee, EmployeeVal> aMap = 
                    new WeakHashMap<Employee, EmployeeVal>();

        Employee emp = new Employee("Vinoth");
        EmployeeVal val = new EmployeeVal("Programmer");

        aMap.put(emp, val);

        emp = null;

        System.gc();
        int count = 0;
        while (0 != aMap.size()) {
            ++count;
            System.gc();
        }
        System.out.println("Took " + count
                + " calls to System.gc() to result in weakHashMap size of : "
                + aMap.size());
    }
}

Output: Took 20 calls to System.gc() to result in aMap size of : 0.

WeakHashMap has only weak references to the keys, not strong references like other Map classes. There are situations which you have to take care when the value or key is strongly referenced though you have used WeakHashMap. This can avoided by wrapping the object in a WeakReference.

import java.lang.ref.WeakReference;
import java.util.HashMap;

public class Test {

    public static void main(String args[]) {
        HashMap<Employee, EmployeeVal> map = 
                      new HashMap<Employee, EmployeeVal>();
        WeakReference<HashMap<Employee, EmployeeVal>> aMap = 
                       new WeakReference<HashMap<Employee, EmployeeVal>>(
                map);

        map = null;

        while (null != aMap.get()) {
            aMap.get().put(new Employee("Vinoth"),
                    new EmployeeVal("Programmer"));
            System.out.println("Size of aMap " + aMap.get().size());
            System.gc();
        }
        System.out.println("Its garbage collected");
    }
}

Soft References.

Soft Reference is slightly stronger that weak reference. Soft reference allows for garbage collection, but begs the garbage collector to clear it only if there is no other option.

The garbage collector does not aggressively collect softly reachable objects the way it does with weakly reachable ones -- instead it only collects softly reachable objects if it really "needs" the memory. Soft references are a way of saying to the garbage collector, "As long as memory isn't too tight, I'd like to keep this object around. But if memory gets really tight, go ahead and collect it and I'll deal with that." The garbage collector is required to clear all soft references before it can throw OutOfMemoryError.

You can also do this...

my_string = "Hello world"

if my_string["Hello"]
  puts 'It has "Hello"'
else
  puts 'No "Hello" found'
end

# => 'It has "Hello"'

This example uses Ruby's String #[] method.

What about injecting the class attribute after the class definition?

class Klass(object):

    @staticmethod  # use as decorator
    def stat_func():
        return 42

    def method(self):
        ret = Klass.stat_func()
        return ret

Klass._ANS = Klass.stat_func()  # inject the class attribute with static method value

You have two ways to enable it.

First, you can set the absolute path of the php module file in your httpd.conf file like this:

LoadModule php5_module /path/to/mods-available/libphp5.so

Second, you can link the module file to the mods-enabled directory:

ln -s /path/to/mods-available/libphp5.so /path/to/mods-enabled/libphp5.so

I had the same problem, tnsnames.ora worked fine for all other tools but SQL Developer would not use it. I tried all the suggestions on the web I could find, including the solutions on the link provided here.
Nothing worked.

It turns out that the database was caching backup copies of tnsnames.ora like tnsnames.ora.bk2, tnsnames09042811AM4501.bak, tnsnames.ora.bk etc. These files were not readable by the average user.

I suspect sqldeveloper is pattern matching for the name and it was trying to read one of these backup copies and couldn't. So it just fails gracefully and shows nothing in drop down list.

The solution is to make all the files readable or delete or move the backup copies out of the Admin directory.

I faced the same 415 http error when sending objects, serialized into JSON, via PUT/PUSH requests to my JAX-rs services, in other words my server was not able to de-serialize the objects from JSON. In my case, the server was able to serialize successfully the same objects in JSON when sending them into its responses.

As mentioned in the other responses I have correctly set the Accept and Content-Type headers to application/json, but it doesn't suffice.

Solution

I simply forgot a default constructor with no parameters for my DTO objects. Yes this is the same reasoning behind @Entity objects, you need a constructor with no parameters for the ORM to instantiate objects and populate the fields later.

Adding the constructor with no parameters to my DTO objects solved my issue. Here follows an example that resembles my code:

Wrong

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {
    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

Right

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {

    public NumberDTO() {
    }

    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

I lost hours, I hope this'll save yours ;-)

You don't show us the declaration of carBootSaleList. However from the exception message I can see that it is of type CarBootSaleList. This type doesn't implement the IEnumerable interface and therefore cannot be used in a foreach.

Your CarBootSaleList class should implement IEnumerable<CarBootSale>:

public class CarBootSaleList : IEnumerable<CarBootSale>
{
    private List<CarBootSale> carbootsales;

    ...

    public IEnumerator<CarBootSale> GetEnumerator()
    {
        return carbootsales.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return carbootsales.GetEnumerator();
    }
}

Web servers respond with a HTTP status code indicating the outcome of the request e.g. 200 (sometimes 202) means success, 404 - not found etc (see here). Assuming the server address part of the URL is correct and you are not getting a socket timeout, the exception is most likely telling you the HTTP status code was other than 200. I would suggest checking the class of the exception and seeing if the exception carries the HTTP status code.

IIRC - The call in question throws a WebException or a descendant. Check the class name to see which one and wrap the call in a try block to trap the condition.

var Test = (from row in Dataset1.Tables[0].AsEnumerable()
            select row.Field<string>("attribute1_name") + row.Field<int>("attribute2_name")).Distinct();

Use the following simple example

function scrollToElement(ele) {
    $(window).scrollTop(ele.offset().top).scrollLeft(ele.offset().left);
}

where ele is your element (jQuery) .. for example : scrollToElement($('#myid'));

 $fp = fopen("$address",'w+');
 if(!$fp)
    echo 'not Open';
        //-----------------------------------
 while(!feof($fp))
     {
        fputs($fp,' ',999);                    
     } 

 fclose($fp);

On my side, i got this problem when i added a new project (Library)

How i solved it

Right click the new added Library go to Properties then Application, under Application change the Target Framework to the framework of all projects.

The problem is that you have project using different target frameworks.

For the string data

 output = []

     def uniq(input):
         if input not in output:
            output.append(input)
 print output     

>>> df.groupby('id').first()
     value
id        
1    first
2    first
3    first
4   second
5    first
6    first
7   fourth

If you need id as column:

>>> df.groupby('id').first().reset_index()
   id   value
0   1   first
1   2   first
2   3   first
3   4  second
4   5   first
5   6   first
6   7  fourth

To get n first records, you can use head():

>>> df.groupby('id').head(2).reset_index(drop=True)
    id   value
0    1   first
1    1  second
2    2   first
3    2  second
4    3   first
5    3   third
6    4  second
7    4   fifth
8    5   first
9    6   first
10   6  second
11   7  fourth
12   7   fifth

tf.all_variables() can get you the information you want.

Also, this commit made today in TensorFlow Learn that provides a function get_variable_names in estimator that you can use to retrieve all variable names easily.

On platforms with the select function (POSIX, Linux, and Windows) you could do:

void sleep(unsigned long msec) {
    timeval delay = {msec / 1000, msec % 1000 * 1000};
    int rc = ::select(0, NULL, NULL, NULL, &delay);
    if(-1 == rc) {
        // Handle signals by continuing to sleep or return immediately.
    }
}

However, there are better alternatives available nowadays.

For Swift 2.1 use this...

    UIGraphicsBeginImageContext(self.view.frame.size)
    UIImage(named: "Cyan.jpg")?.drawInRect(self.view.bounds)

    let image: UIImage! = UIGraphicsGetImageFromCurrentImageContext()

    UIGraphicsEndImageContext()

    self.view.backgroundColor = UIColor(patternImage: image)

df[df.columns.difference(['b'])]

Out: 
          a         c         d
0  0.427809  0.459807  0.333869
1  0.678031  0.668346  0.645951
2  0.996573  0.673730  0.314911
3  0.786942  0.719665  0.330833

For responsive images. You can add the picture and source tags within the figure tag.

<figure>
  <picture>
    <source media="(min-width: 750px)" srcset="images/image_2x.jpg"/>
    <source media="(min-width: 500px)" srcset="images/image.jpg" />
    <img src="images.jpg" alt="An image">
  </picture>
  <figcaption>Caption goes here</figcaption>
</figure>

When using a wildcard, it had to be present on both sides of the refspec, so +refs/heads/*:refs/heads/master will not work. But you can use +HEAD:refs/heads/master:

git config remote.heroku.push +HEAD:refs/heads/master

Also, you can do this directly with git push:

git push heroku +HEAD:master
git push -f heroku HEAD:master

Following Alex's answer I was able to resolve this issue; seems this to be an issue non specific to the packages being installed but of the permissions of homebrew folders.

sudo chown -R `whoami`:admin /usr/local/bin

For some packages, you may also need to do this to /usr/local/share or /usr/local/opt:

sudo chown -R `whoami`:admin /usr/local/share
sudo chown -R `whoami`:admin /usr/local/opt

To modify an image proportionally, simply only alter one of the width/height css properties, leave the other set to auto.

image.style.width = '50%'
image.style.height = 'auto'

This will ensure that its aspect ratio remains the same.

Bear in mind that browsers tend to suck at resizing images nicely - you'll probably find that your resized image looks horrible.

use toUpperCase() or toLowerCase() method of String class.

From the StringBuilder Class documentation:

The String object is immutable. Every time you use one of the methods in the System.String class, you create a new string object in memory, which requires a new allocation of space for that new object. In situations where you need to perform repeated modifications to a string, the overhead associated with creating a new String object can be costly. The System.Text.StringBuilder class can be used when you want to modify a string without creating a new object. For example, using the StringBuilder class can boost performance when concatenating many strings together in a loop.

Before

SELECT SUBSTRING(ParentBGBU,0,CHARINDEX('/',ParentBGBU,0)) FROM dbo.tblHCMMaster;

After

SELECT SUBSTRING(ParentBGBU,CHARINDEX('-',ParentBGBU)+1,LEN(ParentBGBU)) FROM dbo.tblHCMMaster

We’ll create a function called identity that just returns whatever parameter we give it.

identity = (arg) => arg

And a simple array.

arr = [1, 2, 3]

If you call identity with arr, we know what’ll happen

I always compare an MD5 hash of the modulus using these commands:

Certificate: openssl x509 -noout -modulus -in server.crt | openssl md5
Private Key: openssl rsa -noout -modulus -in server.key | openssl md5
CSR: openssl req -noout -modulus -in server.csr | openssl md5

If the hashes match, then those two files go together.

>>> s1 ='arbit'
>>> s2 = 'hello world '.join( [s]*3 )
>>> print s2
arbit hello world arbit hello world arbit

in case u wanna do the validation for "some elements" (not all element) on your form.You can use this method:

$('input[name="element-one"], input[name="element-two"], input[name="element-three"]').valid();

Hope it help everybody :)

EDITED

Same problem here and no answers listed here worked, nor any solutions I could find online. The issue started shortly after Windows 10 anniversary update got applied on my dev PC and only affected my old SQL Server 2005 instance. I was not able to connect to the instance via my Web Applications or even using Sql Management Studio.

For what it's worth, this is what resolved it for me:

1. Open SQL Server Configuration Manager (depending on what version of SQL Server you're running):

   • C:\Windows\SysWOW64\SQLServerManager.msc
   • C:\Windows\SysWOW64\SQLServerManager10.msc OR
   • C:\Windows\SysWOW64\SQLServerManager12.msc OR
   • etc

2. Select SQL Server Services

3. Locate the troubled service and view Properties

   • eg SQL Server (SQL2005) in my case

4. In the Log On tab, change the "Built-in account" to "Network Service"

Which is almost what this random solution said: http://www.kutayzorlu.com/operating-systems/linux-unix-redhat-debian-ubuntu-opensuse-centos/general-server-administrating/error-fixed-a-connection-was-successfully-established-with-the-server-but-then-an-error-occurred-during-the-pre-login-handshake-12405.html

I chose Network Service for no reason at all. Mine was already configured to use Local System. This security doesn't matter to me as it was only problematic on my Local development machine, only accessed locally. I can't advise why this works, but it did.

The long rest in between is due to your keyframe settings. Your current keyframe rules mean that the actual bounce happens only between 40% - 60% of the animation duration (that is, between 1s - 1.5s mark of the animation). Remove those rules and maybe even reduce the animation-duration to suit your needs.

Here is how your original keyframe settings would be interpreted by the browser:

• At 0% (that is, at 0s or start of animation) - translate by 0px in Y axis.
• At 20% (that is, at 0.5s of animation) - translate by 0px in Y axis.
• At 40% (that is, at 1s of animation) - translate by 0px in Y axis.
• At 50% (that is, at 1.25s of animation) - translate by 5px in Y axis. This results in a gradual upward movement.
• At 60% (that is, at 1.5s of animation) - translate by 0px in Y axis. This results in a gradual downward movement.
• At 80% (that is, at 2s of animation) - translate by 0px in Y axis.
• At 100% (that is, at 2.5s or end of animation) - translate by 0px in Y axis.

Use the keyword size instead of fontsize.

I try using the top answer, but it occur Uncaught DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.

I found this is because of cross domain problems, the solution is

function convert(oldImag, callback) {
    var img = new Image();
    img.onload = function(){
        callback(img)
    }
    img.setAttribute('crossorigin', 'anonymous');
    img.src = oldImag.src;
}
function getBase64Image(img,callback) {
    convert(img, function(newImg){
        var canvas = document.createElement("canvas");
        canvas.width = newImg.width;
        canvas.height = newImg.height;
        var ctx = canvas.getContext("2d");
        ctx.drawImage(newImg, 0, 0);
        var base64=canvas.toDataURL("image/png");
        callback(base64)
    })
}
getBase64Image(document.getElementById("imageid"),function(base64){
// base64 in here.
    console.log(base64)
});

here's how:

import pygame
screen=pygame.display.set_mode([640, 480])
screen.fill([255, 255, 255])
red=255
blue=0
green=0
left=50
top=50
width=90
height=90
filled=0
pygame.draw.rect(screen, [red, blue, green], [left, top, width, height], filled)
pygame.display.flip()
running=True
while running:
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            running=False
pygame.quit()

tl;dr

LocalDate.of( 1985 , 1 , 1 )

…or…

LocalDate.of( 1985 , Month.JANUARY , 1 )

Details

The java.util.Date, java.util.Calendar, and java.text.SimpleDateFormat classes were rushed too quickly when Java first launched and evolved. The classes were not well designed or implemented. Improvements were attempted, thus the deprecations you’ve found. Unfortunately the attempts at improvement largely failed. You should avoid these classes altogether. They are supplanted in Java 8 by new classes.

Problems In Your Code

A java.util.Date has both a date and a time portion. You ignored the time portion in your code. So the Date class will take the beginning of the day as defined by your JVM’s default time zone and apply that time to the Date object. So the results of your code will vary depending on which machine it runs or which time zone is set. Probably not what you want.

If you want just the date, without the time portion, such as for a birth date, you may not want to use a Date object. You may want to store just a string of the date, in ISO 8601 format of YYYY-MM-DD. Or use a LocalDate object from Joda-Time (see below).

Joda-Time

First thing to learn in Java: Avoid the notoriously troublesome java.util.Date & java.util.Calendar classes bundled with Java.

As correctly noted in the answer by user3277382, use either Joda-Time or the new java.time.* package in Java 8.

Example Code in Joda-Time 2.3

DateTimeZone timeZoneNorway = DateTimeZone.forID( "Europe/Oslo" );
DateTime birthDateTime_InNorway = new DateTime( 1985, 1, 1, 3, 2, 1, timeZoneNorway );

DateTimeZone timeZoneNewYork = DateTimeZone.forID( "America/New_York" );
DateTime birthDateTime_InNewYork = birthDateTime_InNorway.toDateTime( timeZoneNewYork ); 

DateTime birthDateTime_UtcGmt = birthDateTime_InNorway.toDateTime( DateTimeZone.UTC );

LocalDate birthDate = new LocalDate( 1985, 1, 1 );

Dump to console…

System.out.println( "birthDateTime_InNorway: " + birthDateTime_InNorway );
System.out.println( "birthDateTime_InNewYork: " + birthDateTime_InNewYork );
System.out.println( "birthDateTime_UtcGmt: " + birthDateTime_UtcGmt );
System.out.println( "birthDate: " + birthDate );

When run…

birthDateTime_InNorway: 1985-01-01T03:02:01.000+01:00
birthDateTime_InNewYork: 1984-12-31T21:02:01.000-05:00
birthDateTime_UtcGmt: 1985-01-01T02:02:01.000Z
birthDate: 1985-01-01

java.time

In this case the code for java.time is nearly identical to that of Joda-Time.

We get a time zone (ZoneId), and construct a date-time object assigned to that time zone (ZonedDateTime). Then using the Immutable Objects pattern, we create new date-times based on the old object’s same instant (count of nanoseconds since epoch) but assigned other time zone. Lastly we get a LocalDate which has no time-of-day nor time zone though notice the time zone applies when determining that date (a new day dawns earlier in Oslo than in New York for example).

ZoneId zoneId_Norway = ZoneId.of( "Europe/Oslo" );
ZonedDateTime zdt_Norway = ZonedDateTime.of( 1985 , 1 , 1 , 3 , 2 , 1 , 0 , zoneId_Norway );

ZoneId zoneId_NewYork = ZonedId.of( "America/New_York" );
ZonedDateTime zdt_NewYork = zdt_Norway.withZoneSameInstant( zoneId_NewYork );

ZonedDateTime zdt_Utc = zdt_Norway.withZoneSameInstant( ZoneOffset.UTC );  // Or, next line is similar.
Instant instant = zdt_Norway.toInstant();  // Instant is always in UTC.

LocalDate localDate_Norway = zdt_Norway.toLocalDate();

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Thanks to @cwhisperer. I had the same issue with Doctrine in a Symfony app. I just added the option to my config.yml:

doctrine:
    dbal:
        driver:   pdo_mysql
        options:
            # PDO::MYSQL_ATTR_INIT_COMMAND
            1002: "SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))"

This worked fine for me.

LINQ way:

var lines = File.ReadAllLines("test.txt").Select(a => a.Split(';'));
var csv = from line in lines
          select (from piece in line
                  select piece);

^^Wrong - Edit by Nick

It appears the original answerer was attempting to populate csv with a 2 dimensional array - an array containing arrays. Each item in the first array contains an array representing that line number with each item in the nested array containing the data for that specific column.

var csv = from line in lines
          select (line.Split(',')).ToArray();

                alert($(this).val());
            });
        }

            }
        });
    }

The use of boost::preprocessor makes possible an elegant solution like the following:

Step 1: include the header file:

#include "EnumUtilities.h"

Step 2: declare the enumeration object with the following syntax:

MakeEnum( TestData,
         (x)
         (y)
         (z)
         );

Step 3: use your data:

Getting the number of elements:

td::cout << "Number of Elements: " << TestDataCount << std::endl;

Getting the associated string:

std::cout << "Value of " << TestData2String(x) << " is " << x << std::endl;
std::cout << "Value of " << TestData2String(y) << " is " << y << std::endl;
std::cout << "Value of " << TestData2String(z) << " is " << z << std::endl;

Getting the enum value from the associated string:

std::cout << "Value of x is " << TestData2Enum("x") << std::endl;
std::cout << "Value of y is " << TestData2Enum("y") << std::endl;
std::cout << "Value of z is " << TestData2Enum("z") << std::endl;

This looks clean and compact, with no extra files to include. The code I wrote within EnumUtilities.h is the following:

#include <boost/preprocessor/seq/for_each.hpp>
#include <string>

#define REALLY_MAKE_STRING(x) #x
#define MAKE_STRING(x) REALLY_MAKE_STRING(x)
#define MACRO1(r, data, elem) elem,
#define MACRO1_STRING(r, data, elem)    case elem: return REALLY_MAKE_STRING(elem);
#define MACRO1_ENUM(r, data, elem)      if (REALLY_MAKE_STRING(elem) == eStrEl) return elem;


#define MakeEnum(eName, SEQ) \
    enum eName { BOOST_PP_SEQ_FOR_EACH(MACRO1, , SEQ) \
    last_##eName##_enum}; \
    const int eName##Count = BOOST_PP_SEQ_SIZE(SEQ); \
    static std::string eName##2String(const enum eName eel) \
    { \
        switch (eel) \
        { \
        BOOST_PP_SEQ_FOR_EACH(MACRO1_STRING, , SEQ) \
        default: return "Unknown enumerator value."; \
        }; \
    }; \
    static enum eName eName##2Enum(const std::string eStrEl) \
    { \
        BOOST_PP_SEQ_FOR_EACH(MACRO1_ENUM, , SEQ) \
        return (enum eName)0; \
    };

There are some limitation, i.e. the ones of boost::preprocessor. In this case, the list of constants cannot be larger than 64 elements.

Following the same logic, you could also think to create sparse enum:

#define EnumName(Tuple)                 BOOST_PP_TUPLE_ELEM(2, 0, Tuple)
#define EnumValue(Tuple)                BOOST_PP_TUPLE_ELEM(2, 1, Tuple)
#define MACRO2(r, data, elem)           EnumName(elem) EnumValue(elem),
#define MACRO2_STRING(r, data, elem)    case EnumName(elem): return BOOST_PP_STRINGIZE(EnumName(elem));

#define MakeEnumEx(eName, SEQ) \
    enum eName { \
    BOOST_PP_SEQ_FOR_EACH(MACRO2, _, SEQ) \
    last_##eName##_enum }; \
    const int eName##Count = BOOST_PP_SEQ_SIZE(SEQ); \
    static std::string eName##2String(const enum eName eel) \
    { \
        switch (eel) \
        { \
        BOOST_PP_SEQ_FOR_EACH(MACRO2_STRING, _, SEQ) \
        default: return "Unknown enumerator value."; \
        }; \
    };  

In this case, the syntax is:

MakeEnumEx(TestEnum,
           ((x,))
           ((y,=1000))
           ((z,))
           );

Usage is similar as above (minus the eName##2Enum function, that you could try to extrapolate from the previous syntax).

I tested it on mac and linux, but be aware that boost::preprocessor may not be fully portable.

Exporting each variable from your variables file. Then importing them with * as in your other file and exporting the as a constant from that file will give you a dynamic object with the named exports from the first file being attributes on the object exported from the second.

Variables.js

export const var1 = 'first';
export const var2 = 'second':
...
export const varN = 'nth';

Other.js

import * as vars from './Variables';

export const Variables = vars;

Third.js

import { Variables } from './Other';

Variables.var2 === 'second'

Just be sure you have used double apostrophe ('')

String text = java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
System.out.println(text);

Edit:

Within a String, a pair of single quotes can be used to quote any arbitrary characters except single quotes. For example, pattern string "'{0}'" represents string "{0}", not a FormatElement. ...

Any unmatched quote is treated as closed at the end of the given pattern. For example, pattern string "'{0}" is treated as pattern "'{0}'".

I'm using this function based on @Murph answer. It searches inside the current directory and lists the full path:

function findit
{
$filename = $args[0];
gci -recurse -filter "*${filename}*" -file -ErrorAction SilentlyContinue | foreach-object {
    $place_path = $_.directory
    echo "${place_path}\${_}"
    }
}

Example usage: findit myfile

<input type="text" value="Your value">

Use the value attribute for the pre filled in values.

I had the same problem and it was due to several installations of cygwin.

Check the link (the icon) that you click on to start the terminal. In case it does not point to the directory of your updated cygwin installation, you have the wrong installation of cygwin. When updating, double check the location of cygwin, and start exactly this instance of cygwin.

Take a look at the excellent Schematics lib

https://github.com/schematics/schematics

It allows you to created typed data structures that can serialize/deserialize from python to Javascript flavour, eg:

class MapPrice(Model):
    price_before_vat = DecimalType(serialized_name='priceBeforeVat')
    vat_rate = DecimalType(serialized_name='vatRate')
    vat = DecimalType()
    total_price = DecimalType(serialized_name='totalPrice')

There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.

First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!

It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.

Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.

I doubt there is one... It depends on browser, on printer (physical max dpi) and its driver, on paper size as you point out (and I might want to print on B5 paper too...), on settings (landscape or portrait?), plus you often can change the scale (percentage), etc.
Let the users tweak their settings...

To add to Mosh Feu answer, if the tabs where created on the fly like in my case, you would use the following code

$(document).on('shown.bs.tab', 'a[data-toggle="tab"]', function (e) {
    var tab = $(e.target);
    var contentId = tab.attr("href");

    //This check if the tab is active
    if (tab.parent().hasClass('active')) {
         console.log('the tab with the content id ' + contentId + ' is visible');
    } else {
         console.log('the tab with the content id ' + contentId + ' is NOT visible');
    }

});

I hope this helps someone

I solved this problem with

if( !mysql_ping($link) ) $link = mysql_connect("$MYSQL_Host","$MYSQL_User","$MYSQL_Pass", true);

Here is a bulky but fast version :

def nbdigit ( x ):
    if x >= 10000000000000000 : # 17 -
        return len( str( x ))
    if x < 100000000 : # 1 - 8
        if x < 10000 : # 1 - 4
            if x < 100             : return (x >= 10)+1 
            else                   : return (x >= 1000)+3
        else: # 5 - 8                                                 
            if x < 1000000         : return (x >= 100000)+5 
            else                   : return (x >= 10000000)+7
    else: # 9 - 16 
        if x < 1000000000000 : # 9 - 12
            if x < 10000000000     : return (x >= 1000000000)+9 
            else                   : return (x >= 100000000000)+11
        else: # 13 - 16
            if x < 100000000000000 : return (x >= 10000000000000)+13 
            else                   : return (x >= 1000000000000000)+15

Only 5 comparisons for not too big numbers. On my computer it is about 30% faster than the math.log10 version and 5% faster than the len( str()) one. Ok... no so attractive if you don't use it furiously.

And here is the set of numbers I used to test/measure my function:

n = [ int( (i+1)**( 17/7. )) for i in xrange( 1000000 )] + [0,10**16-1,10**16,10**16+1]

NB: it does not manage negative numbers, but the adaptation is easy...

For Mac OS X:

pip install --ignore-installed six

Execute chmod 777 -R scripts/, it worked fine for me ;)

Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:

https://<region>.amazonaws.com/<bucket-name>/<key>

Where <region> is something like s3-ap-southeast-2.

Click on the item in the S3 GUI to get the link for your bucket.

Try this:

   var myDouble = myString.bridgeToObjectiveC().doubleValue
   println(myDouble)

NOTE

Removed in Beta 5. This no longer works ?

Create an XML layout first in your project's res/layout/main.xml folder:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
    <Button
        android:id="@+id/addBtn"
        android:text="Add New Item"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="addItems"/>
    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="false"
    />
</LinearLayout>

This is a simple layout with a button on the top and a list view on the bottom. Note that the ListView has the id @android:id/list which defines the default ListView a ListActivity can use.

public class ListViewDemo extends ListActivity {
    //LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
    ArrayList<String> listItems=new ArrayList<String>();

    //DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
    ArrayAdapter<String> adapter;

    //RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
    int clickCounter=0;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
        adapter=new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1,
            listItems);
        setListAdapter(adapter);
    }

    //METHOD WHICH WILL HANDLE DYNAMIC INSERTION
    public void addItems(View v) {
        listItems.add("Clicked : "+clickCounter++);
        adapter.notifyDataSetChanged();
    }
}

android.R.layout.simple_list_item_1 is the default list item layout supplied by Android, and you can use this stock layout for non-complex things.

listItems is a List which holds the data shown in the ListView. All the insertion and removal should be done on listItems; the changes in listItems should be reflected in the view. That's handled by ArrayAdapter<String> adapter, which should be notified using:

adapter.notifyDataSetChanged();

An Adapter is instantiated with 3 parameters: the context, which could be your activity/listactivity; the layout of your individual list item; and lastly, the list, which is the actual data to be displayed in the list.

... WHERE date_column >='2012-12-25' AND date_column <'2012-12-26' may potentially work better(if you have an index on date_column) than DATE.

try this:

select salesid,count (salesid) from AXDelNotesNoTracking group by salesid having count (salesid) >1

SET A uses short-circuiting boolean operators.

What 'short-circuiting' means in the context of boolean operators is that for a set of booleans b1, b2, ..., bn, the short circuit versions will cease evaluation as soon as the first of these booleans is true (||) or false (&&).

For example:

// 2 == 2 will never get evaluated because it is already clear from evaluating
// 1 != 1 that the result will be false.
(1 != 1) && (2 == 2)

// 2 != 2 will never get evaluated because it is already clear from evaluating
// 1 == 1 that the result will be true.
(1 == 1) || (2 != 2)

Please write following code in menu.xml file:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:my_menu_tutorial_app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      tools:context="com.example.mymenus.menu_app.MainActivity">
<item android:id="@+id/item_one"
      android:icon="@drawable/menu_icon"
      android:orderInCategory="l01"
      android:title="Item One"
      my_menu_tutorial_app:showAsAction="always">
      <!--sub-menu-->
      <menu>
          <item android:id="@+id/sub_one"
                android:title="Sub-menu item one" />
          <item android:id="@+id/sub_two"
                android:title="Sub-menu item two" />
      </menu>

Also write this java code in activity class file:

public boolean onOptionsItemSelected(MenuItem item)
{
    super.onOptionsItemSelected(item);
    Toast.makeText(this, "Menus item selected: " +
        item.getTitle(), Toast.LENGTH_SHORT).show();
    switch (item.getItemId())
    {
        case R.id.sub_one:
            isItemOneSelected = true;
            supportInvalidateOptionsMenu();
            return true;
        case MENU_ITEM + 1:
            isRemoveItem = true;
            supportInvalidateOptionsMenu();
            return true;
        default:
            return false;
    }
}

This is the easiest way to display menus in action bar.

I use

"0x%X" % n

where n is the decimal number to convert.

People looking for SSH public key...

If you're looking to extract the public key for use with OpenSSH, you will need to get the public key a bit differently

$ ssh-keygen -y -f mykey.pem > mykey.pub

This public key format is compatible with OpenSSH. Append the public key to remote:~/.ssh/authorized_keys and you'll be good to go

docs from SSH-KEYGEN(1)

ssh-keygen -y [-f input_keyfile]  

-y This option will read a private OpenSSH format file and print an OpenSSH public key to stdout.

Open cmd with "Run as administrator" and execute the command pip install mitmproxy. It will install it.
