Depending on the version, do:

version <2.3.0

Kill a hadoop job:

hadoop job -kill $jobId

You can get a list of all jobId's doing:

hadoop job -list

version >=2.3.0

Kill a hadoop job:

yarn application -kill $ApplicationId

You can get a list of all ApplicationId's doing:

yarn application -list

int rgb = new Color(r, g, b).getRGB();

For install with zsh and Homebrew:

brew install nvm

Then Add the following to ~/.zshrc or your desired shell configuration file:

export NVM_DIR="$HOME/.nvm"
. "/usr/local/opt/nvm/nvm.sh"

Then install a node version and use it.

nvm install 7.10.1
nvm use 7.10.1

Java doesn't know what T is until you instantiate a type.

Maybe you can execute static methods by calling Clazz<T>.doit(something) but it sounds like you can't.

The other way to handle things is to put the type parameter in the method itself:

static <U> void doIt(U object)

which doesn't get you the right restriction on U, but it's better than nothing....

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

If your intention was to find a way to represent null in an enumeration of singleton objects, then it's a bad idea to (de)reference null (it C++11, nullptr).

Why not declare static singleton object that represents NULL within the class as follows and add a cast-to-pointer operator that returns nullptr ?

Edit: Corrected several mistypes and added if-statement in main() to test for the cast-to-pointer operator actually working (which I forgot to.. my bad) - March 10 2015 -

// Error.h
class Error {
public:
  static Error& NOT_FOUND;
  static Error& UNKNOWN;
  static Error& NONE; // singleton object that represents null

public:
  static vector<shared_ptr<Error>> _instances;
  static Error& NewInstance(const string& name, bool isNull = false);

private:
  bool _isNull;
  Error(const string& name, bool isNull = false) : _name(name), _isNull(isNull) {};
  Error() {};
  Error(const Error& src) {};
  Error& operator=(const Error& src) {};

public:
  operator Error*() { return _isNull ? nullptr : this; }
};

// Error.cpp
vector<shared_ptr<Error>> Error::_instances;
Error& Error::NewInstance(const string& name, bool isNull = false)
{
  shared_ptr<Error> pNewInst(new Error(name, isNull)).
  Error::_instances.push_back(pNewInst);
  return *pNewInst.get();
}

Error& Error::NOT_FOUND = Error::NewInstance("NOT_FOUND");
//Error& Error::NOT_FOUND = Error::NewInstance("UNKNOWN"); Edit: fixed
//Error& Error::NOT_FOUND = Error::NewInstance("NONE", true); Edit: fixed
Error& Error::UNKNOWN = Error::NewInstance("UNKNOWN");
Error& Error::NONE = Error::NewInstance("NONE");

// Main.cpp
#include "Error.h"

Error& getError() {
  return Error::UNKNOWN;
}

// Edit: To see the overload of "Error*()" in Error.h actually working
Error& getErrorNone() {
  return Error::NONE;
}

int main(void) {
  if(getError() != Error::NONE) {
    return EXIT_FAILURE;
  }

  // Edit: To see the overload of "Error*()" in Error.h actually working
  if(getErrorNone() != nullptr) {
    return EXIT_FAILURE;
  }
}

This simple 32 lines gist lets you identify a given stylesheet and change its styles very easily:

var styleSheet = StyleChanger("my_custom_identifier");
styleSheet.change("darkolivegreen", "blue");

See this tutorial: Loading images with native JavaScript and handling of events for showing loading spinners

It tells you how to load images with native JavaScript and how to handle events for showing loading spinners. Basically, you create a new Image(); and handle the event correctly then. That should work in all browsers, even in IE7 (maybe even below IE7, but I did not test that...)

I have tried all solution. The -lopencv_core -lopencv_imgproc -lopencv_highgui in comments solved my problem. And know my command line looks like this in geany:

g++ -lopencv_core -lopencv_imgproc -lopencv_highgui  -o "%e" "%f"

When I build:

g++ -lopencv_core -lopencv_imgproc -lopencv_highgui  -o "opencv" "opencv.cpp" (in directory: /home/fedora/Desktop/Implementations)

The headers are:

#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"

from the debug info, it seems that the VideoIntent from the MainActivity cannot send the path of the video to VideoActivity. It gives a NullPointerException error from the uriString. I think some of that code from VideoActivity:

Intent myIntent = getIntent();
String uri = myIntent.getStringExtra("uri");
Bundle b = myIntent.getExtras();

startVideo(b.getString(uri));

Cannot receive the uri from here:

public void playsquirrelmp4(View v) {
    Intent VideoIntent = (new Intent(this, VideoActivity.class));
    VideoIntent.putExtra("android.resource://" + getPackageName()
        + "/"+   R.raw.squirrel, uri);
    startActivity(VideoIntent);
}

Have you tried actually adding the Access-Control-Allow-Origin header to the response sent from your server? Like, Access-Control-Allow-Origin: *?

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

You need to use an explicit color value (e.g. #000 or blue) for the color-property. none is invalid here. The initial value is browser-specific and cannot be restored using CSS. Keep in mind that there are some other pseudo-classes than :active, too.

Using Google Collections, assuming K is your key type:

Maps.filterKeys(treeMap, new Predicate<K>() {
  @Override
  public boolean apply(K key) {
    return false; //return true here if you need the entry to be in your new map
  }});

You can use filterEntries instead if you need the value as well.

I'm using this alias for checking out a branch in a temporary directory:

[alias]
    cot = "!TEMP=$(mktemp -d); f() { git worktree prune && git worktree add $TEMP $1 && zsh -c \"cd $TEMP; zsh\";}; f" # checkout branch in temporary directory

Usage:

git cot mybranch

You are then dropped in a new shell in the temporary directory where you can work on the branch. You can even use git commands in this directory.

When you're done, delete the directory and run:

git worktree prune

This is also done automatically in the alias, before adding a new worktree.

In the interest of completeness, it should be pointed out that there are representations of strings on various platforms in which the number of bytes per character varies depending on the character. Old-school programmers would refer to this as DBCS (Double Byte Character Set). Modern programmers more commonly encounter this in UTF-8 (as well as UTF-16 and others). There are other such encodings as well.

In any of these variable-width encoding schemes, the simple algorithms posted here (evil, non-evil or otherwise) would not work correctly at all! In fact, they could even cause the string to become illegible or even an illegal string in that encoding scheme. See Juan Pablo Califano's answer for some good examples.

std::reverse() potentially would still work in this case, as long as your platform's implementation of the Standard C++ Library (in particular, string iterators) properly took this into account.

There are several options, including using the method you demonstrate, With, and using a variable.

My preference is option 4 below: Dim a variable of type Worksheet and store the worksheet and call the methods on the variable or pass it to functions, however any of the options work.

Sub Test()
  Dim SheetName As String
  Dim SearchText As String
  Dim FoundRange As Range

  SheetName = "test"      
  SearchText = "abc"

  ' 0. If you know the sheet is the ActiveSheet, you can use if directly.
  Set FoundRange = ActiveSheet.UsedRange.Find(What:=SearchText)
  ' Since I usually have a lot of Subs/Functions, I don't use this method often.
  ' If I do, I store it in a variable to make it easy to change in the future or
  ' to pass to functions, e.g.: Set MySheet = ActiveSheet
  ' If your methods need to work with multiple worksheets at the same time, using
  ' ActiveSheet probably isn't a good idea and you should just specify the sheets.

  ' 1. Using Sheets or Worksheets (Least efficient if repeating or calling multiple times)
  Set FoundRange = Sheets(SheetName).UsedRange.Find(What:=SearchText)
  Set FoundRange = Worksheets(SheetName).UsedRange.Find(What:=SearchText)

  ' 2. Using Named Sheet, i.e. Sheet1 (if Worksheet is named "Sheet1"). The
  ' sheet names use the title/name of the worksheet, however the name must
  ' be a valid VBA identifier (no spaces or special characters. Use the Object
  ' Browser to find the sheet names if it isn't obvious. (More efficient than #1)
  Set FoundRange = Sheet1.UsedRange.Find(What:=SearchText)

  ' 3. Using "With" (more efficient than #1)
  With Sheets(SheetName)
    Set FoundRange = .UsedRange.Find(What:=SearchText)
  End With
  ' or possibly...
  With Sheets(SheetName).UsedRange
    Set FoundRange = .Find(What:=SearchText)
  End With

  ' 4. Using Worksheet variable (more efficient than 1)
  Dim MySheet As Worksheet
  Set MySheet = Worksheets(SheetName)
  Set FoundRange = MySheet.UsedRange.Find(What:=SearchText)

  ' Calling a Function/Sub
  Test2 Sheets(SheetName) ' Option 1
  Test2 Sheet1 ' Option 2
  Test2 MySheet ' Option 4

End Sub

Sub Test2(TestSheet As Worksheet)
    Dim RowIndex As Long
    For RowIndex = 1 To TestSheet.UsedRange.Rows.Count
        If TestSheet.Cells(RowIndex, 1).Value = "SomeValue" Then
            ' Do something
        End If
    Next RowIndex
End Sub

Now days I believe it's preferred to use a function form of typeof() so...

if(filename === undefined || typeof(filename) !== "string" || filename === "") {
   console.log("no filename aborted.");
   return;
}

Each argument passed via command line can be accessed with: Wscript.Arguments.Item(0) Where the zero is the argument number: ie, 0, 1, 2, 3 etc.

So in your code you could have:

strFolder = Wscript.Arguments.Item(0) 

Set FSO = CreateObject("Scripting.FileSystemObject")
Set File = FSO.OpenTextFile(strFolder, 2, True)
File.Write "testing"
File.Close
Set File = Nothing
Set FSO = Nothing
Set workFolder = Nothing

Using wscript.arguments.count, you can error trap in case someone doesn't enter the proper value, etc.

MS Technet examples

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

Here is how I would do that:

$sum = 5;
$product = 6;

$found = FALSE;
for ($a = 1; $a < $sum; $a++) {
  $b = $sum - $a;
  if ($a * $b == $product) {
    $found = TRUE;
    break;
  }
}

if ($found) {
  echo "The answer is a = $a, b = $b.";
} else {
  echo "There is no answer where a and b are both integers.";
}

Basically, start at $a = 1 and $b = $sum - $a, step through it one at a time since we know then that $a + $b == $sum is always true, and multiply $a and $b to see if they equal $product. If they do, that's the answer.

See it working

Whether that is the most efficient method is very much debatable.

With code clarity in mind, my opinion is that using XOR in boolean checks is not typical usage for the XOR bitwise operator. From my experience, bitwise XOR in Java is typically used to implement a mask flag toggle behavior:

flags = flags ^ MASK;

This article by Vipan Singla explains the usage case more in detail.

If you need to use bitwise XOR as in your example, comment why you use it, since it's likely to require even a bitwise literate audience to stop in their tracks to understand why you are using it.

You can use the following SQL to compare both date and time -

Select * From temp where mydate > STR_TO_DATE('2009-06-29 04:00:44', '%Y-%m-%d %H:%i:%s');

Attached mysql output when I used same SQL on same kind of table and field that you mentioned in the problem-

It should work perfect.

A worked, completed and simple example:

package io.github.baijifeilong.excel;

import lombok.SneakyThrows;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import java.io.FileOutputStream;

            row.setRowStyle(createCellStyle());
            row.getRowStyle().getFont().setBold(true);
            row.createCell(0).setCellValue("Alpha");
            row.createCell(1).setCellValue("Beta");
            row.createCell(2).setCellValue("Gamma");
        }}.write(new FileOutputStream("demo.xlsx"));
    }
}

I think you mean the active state

 button:active{
  //some styling
 }

These are all the possible pseudo states a link can have in CSS:

a:link {color:#FF0000;}    /* unvisited link, same as regular 'a' */
a:hover {color:#FF00FF;}   /* mouse over link */
a:focus {color:#0000FF;}   /* link has focus */
a:active {color:#0000FF;}  /* selected link */
a:visited {color:#00FF00;} /* visited link */

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

For anyone else looking for answer to the question when dealing with different linebreaks:

string.replaceAll("(\n|\r|\r\n)$", ""); // Java 7
string.replaceAll("\\R$", "");          // Java 8

This should remove exactly the last line break and preserve all other whitespace from string and work with Unix (\n), Windows (\r\n) and old Mac (\r) line breaks: https://stackoverflow.com/a/20056634, https://stackoverflow.com/a/49791415. "\\R" is matcher introduced in Java 8 in Pattern class: https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html

This passes these tests:

// Windows:
value = "\r\n test \r\n value \r\n";
assertEquals("\r\n test \r\n value ", value.replaceAll("\\R$", ""));

// Unix:
value = "\n test \n value \n";
assertEquals("\n test \n value ", value.replaceAll("\\R$", ""));

// Old Mac:
value = "\r test \r value \r";
assertEquals("\r test \r value ", value.replaceAll("\\R$", ""));

There are many ways to get jQuery AJAX response. I am sharing with you two common approaches:

First:

use async=false and within function return ajax-object and later get response ajax-object.responseText

/**
 * jQuery ajax method with async = false, to return response
 * @param  {mix}  selector - your selector
 * @return {mix}           - your ajax response/error
 */
function isSession(selector) {
    return $.ajax({
        type: "POST",
        url: '/order.html',
        data: {
            issession: 1,
            selector: selector
        },
        dataType: "html",
        async: !1,
        error: function() {
            alert("Error occured")
        }
    });
}
// global param
var selector = !0;
// get return ajax object
var ajaxObj = isSession(selector);
// store ajax response in var
var ajaxResponse = ajaxObj.responseText;
// check ajax response
console.log(ajaxResponse);
// your ajax callback function for success
ajaxObj.success(function(response) {
    alert(response);
});

Second:

use $.extend method and make a new function like ajax

/**
 * xResponse function
 *
 * xResponse method is made to return jQuery ajax response
 * 
 * @param  {string} url   [your url or file]
 * @param  {object} your ajax param
 * @return {mix}       [ajax response]
 */
$.extend({
    xResponse: function(url, data) {
        // local var
        var theResponse = null;
        // jQuery ajax
        $.ajax({
            url: url,
            type: 'POST',
            data: data,
            dataType: "html",
            async: false,
            success: function(respText) {
                theResponse = respText;
            }
        });
        // Return the response text
        return theResponse;
    }
});

// set ajax response in var
var xData = $.xResponse('temp.html', {issession: 1,selector: true});

// see response in console
console.log(xData);

you can make it as large as you want...

it' s not so complicated: in your dirctive, use an alias: scope:{alias:'=ngModel'}

.directive('dateselect', function () {
return {
    restrict: 'E',
    transclude: true,
    scope:{
        bindModel:'=ngModel'
    },
    template:'<input ng-model="bindModel"/>'
}

in your html, use as normal

<dateselect ng-model="birthday"></dateselect>

:goto 21490 will take you to the 21490th byte in the buffer.

We managed to get this working exactly as described in the OP, and hopefully someone else can make use of the solution. Here's what we did:

Set up the security context like so:

<security:http realm="Protected API" use-expressions="true" auto-config="false" create-session="stateless" entry-point-ref="CustomAuthenticationEntryPoint">
    <security:custom-filter ref="authenticationTokenProcessingFilter" position="FORM_LOGIN_FILTER" />
    <security:intercept-url pattern="/authenticate" access="permitAll"/>
    <security:intercept-url pattern="/**" access="isAuthenticated()" />
</security:http>

<bean id="CustomAuthenticationEntryPoint"
    class="com.demo.api.support.spring.CustomAuthenticationEntryPoint" />

<bean id="authenticationTokenProcessingFilter"
    class="com.demo.api.support.spring.AuthenticationTokenProcessingFilter" >
    <constructor-arg ref="authenticationManager" />
</bean>

As you can see, we've created a custom AuthenticationEntryPoint, which basically just returns a 401 Unauthorized if the request wasn't authenticated in the filter chain by our AuthenticationTokenProcessingFilter.

CustomAuthenticationEntryPoint:

public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException authException) throws IOException, ServletException {
        response.sendError( HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized: Authentication token was either missing or invalid." );
    }
}

AuthenticationTokenProcessingFilter:

public class AuthenticationTokenProcessingFilter extends GenericFilterBean {

    @Autowired UserService userService;
    @Autowired TokenUtils tokenUtils;
    AuthenticationManager authManager;

    public AuthenticationTokenProcessingFilter(AuthenticationManager authManager) {
        this.authManager = authManager;
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        @SuppressWarnings("unchecked")
        Map<String, String[]> parms = request.getParameterMap();

        if(parms.containsKey("token")) {
            String token = parms.get("token")[0]; // grab the first "token" parameter

            // validate the token
            if (tokenUtils.validate(token)) {
                // determine the user based on the (already validated) token
                UserDetails userDetails = tokenUtils.getUserFromToken(token);
                // build an Authentication object with the user's info
                UsernamePasswordAuthenticationToken authentication = 
                        new UsernamePasswordAuthenticationToken(userDetails.getUsername(), userDetails.getPassword());
                authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails((HttpServletRequest) request));
                // set the authentication into the SecurityContext
                SecurityContextHolder.getContext().setAuthentication(authManager.authenticate(authentication));         
            }
        }
        // continue thru the filter chain
        chain.doFilter(request, response);
    }
}

Obviously, TokenUtils contains some privy (and very case-specific) code and can't be readily shared. Here's its interface:

public interface TokenUtils {
    String getToken(UserDetails userDetails);
    String getToken(UserDetails userDetails, Long expiration);
    boolean validate(String token);
    UserDetails getUserFromToken(String token);
}

That ought to get you off to a good start. Happy coding. :)

If you only want to capitalize the first letter of a string named input and leave the rest alone:

String output = input.substring(0, 1).toUpperCase() + input.substring(1);

Now output will have what you want. Check that your input is at least one character long before using this, otherwise you'll get an exception.

Note: in C# the term "function" is often replaced by the term "method". For the sake of this question there is no difference, so I'll just use the term "function".

Thats not true. you may read about (func type+ Lambda expressions),( anonymous function"using delegates type"),(action type +Lambda expressions ),(Predicate type+Lambda expressions). etc...etc... this will work.

           b = Convert.ToInt32(Console.ReadLine());

           c=funcAdd.Invoke(a, b);
           Console.WriteLine(Convert.ToString(c));

        }

     }
}

Spring Boot, v2.3.0.RELEASE

Recommended (In application.properties):

logging.level.org.hibernate.SQL=DEBUG //logs all SQL DML statements
logging.level.org.hibernate.type=TRACE //logs all JDBC parameters 

parameters

Note:
The above will not give you a pretty-print though.
You can add it as a configuration:

properties.put("hibernate.format_sql", "true");

or as per below.

Works but NOT recommended

spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

Reason: It's better to let the logging framework manage/optimize the output for you + it doesn't give you the prepared statement parameters.

Jedi Code Library provides an enhanced StringList with built-in Split function, that is capable of both adding and replacing the existing text. It also provides reference-counted interface. So this can be used even with older Delphi versions that have no SplitStrings and without careful and a bit tedious customizations of stock TStringList to only use specified delimiters.

For example given text file of lines like Dog 5 4 7 one can parse them using:

var slF, slR: IJclStringList; ai: TList<integer>; s: string; i: integer;
    action: procedure(const Name: string; Const Data: array of integer);

slF := TJclStringList.Create; slF.LoadFromFile('some.txt');
slR := TJclStringList.Create;
for s in slF do begin
    slR.Split(s, ' ', true);
    ai := TList<Integer>.Create;
    try
       for i := 1 to slR.Count - 1 do
           ai.Add(StrToInt(slR[i]));
       action(slR[0], ai.ToArray);
    finally ai.Free; end;
end;

You can set the spring profile by supplying -Dspring.profiles.active=<env>

For java files in source(src) directory, you can use by System.getProperty("spring.profiles.active")

For java files in test directory you can supply

• SPRING_PROFILES_ACTIVE to <env>

OR

Since, "environment", "jvmArgs" and "systemProperties" are ignored for the "test" task. In root build.gradle add a task to set jvm property and environment variable.

test {
    def profile = System.properties["spring.profiles.active"]
    systemProperty "spring.profiles.active",profile
    environment "SPRING.PROFILES_ACTIVE", profile
    println "Running ${project} tests with profile: ${profile}"
}

Typically you need to do 5 things to include a library in your project:

1) Add #include statements necessary files with declarations/interfaces, e.g.:

#include "library.h"

2) Add an include directory for the compiler to look into

-> Configuration Properties/VC++ Directories/Include Directories (click and edit, add a new entry)

3) Add a library directory for *.lib files:

-> project(on top bar)/properties/Configuration Properties/VC++ Directories/Library Directories (click and edit, add a new entry)

4) Link the lib's *.lib files

-> Configuration Properties/Linker/Input/Additional Dependencies (e.g.: library.lib;

5) Place *.dll files either:

-> in the directory you'll be opening your final executable from or into Windows/system32

Thing is an inner class with an automatic connection to an instance of Hello. You get a compile error because there is no instance of Hello for it to attach to. You can fix it most easily by changing it to a static nested class which has no connection:

static class Thing

You could declare a table variable (Declaring a variable of type table):

declare @MonthsSale table(monthnr int)
insert into @MonthsSale (monthnr) values (1)
insert into @MonthsSale (monthnr) values (2)
....

You can add extra columns as you like:

declare @MonthsSale table(monthnr int, totalsales tinyint)

You can update the table variable like any other table:

update m
set m.TotalSales = sum(s.SalesValue)
from @MonthsSale m
left join Sales s on month(s.SalesDt) = m.MonthNr

For the allowed characters you can use

^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$

to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.

For the invalid characters you can use

[<>'"/;`%]

to check for them.

To combine both into a single regex you can use

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

but you'd need a regex engine that allows lookahead.

The following snippet will start an operation in a separate thread, then wait for up to 10 seconds for the operation to complete. If the operation does not complete in time, the code will attempt to cancel the operation, then continue on its merry way. Even if the operation cannot be cancelled easily, the parent thread will not wait for the child thread to terminate.

ExecutorService executorService = getExecutorService();
Future<SomeClass> future = executorService.submit(new Callable<SomeClass>() {
    public SomeClass call() {
        // Perform long-running task, return result. The code should check
        // interrupt status regularly, to facilitate cancellation.
    }
});
try {
    // Real life code should define the timeout as a constant or
    // retrieve it from configuration
    SomeClass result = future.get(10, TimeUnit.SECONDS);
    // Do something with the result
} catch (TimeoutException e) {
    future.cancel(true);
    // Perform other error handling, e.g. logging, throwing an exception
}

The getExecutorService() method can be implemented in a number of ways. If you do not have any particular requirements, you can simply call Executors.newCachedThreadPool() for thread pooling with no upper limit on the number of threads.

Option 1:

You can set CMake variables at command line like this:

cmake -D CMAKE_C_COMPILER="/path/to/your/c/compiler/executable" -D CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable" /path/to/directory/containing/CMakeLists.txt

See this to learn how to create a CMake cache entry.

Option 2:

In your shell script build_ios.sh you can set environment variables CC and CXX to point to your C and C++ compiler executable respectively, example:

export CC=/path/to/your/c/compiler/executable
export CXX=/path/to/your/cpp/compiler/executable
cmake /path/to/directory/containing/CMakeLists.txt

Option 3:

Edit the CMakeLists.txt file of "Assimp": Add these lines at the top (must be added before you use project() or enable_language() command)

set(CMAKE_C_COMPILER "/path/to/your/c/compiler/executable")
set(CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable")

See this to learn how to use set command in CMake. Also this is a useful resource for understanding use of some of the common CMake variables.

Here is the relevant entry from the official FAQ: https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-do-i-use-a-different-compiler

You need to go for a loop:

for (int i = 0; i < sizeof(foo) / sizeof(float); ++i)
   printf("%f", foo[i]);
printf("\n");

Maybe just "border-width" instead of "border-weight"? There is no "border-weight" and this property is just ignored and default width is used instead.

I hope I am not adding something obvious, but I have been struggling with Django, Ajax, and JSON on this.

Assuming that in your HTML code you do use double quotes, as normally should be, I highly suggest to use single quotes for the rest in JavaScript.

So I agree with ady, but with some care.

My bottom line is:

In JavaScript it probably doesn't matter, but as soon as you embed it inside HTML or the like you start to get troubles. You should know what is actually escaping, reading, passing your string.

My simple case was:

tbox.innerHTML = tbox.innerHTML + '<div class="thisbox_des" style="width:210px;" onmouseout="clear()"><a href="/this/thislist/'
                   + myThis[i].pk +'"><img src="/site_media/'
                   + myThis[i].fields.thumbnail +'" height="80" width="80" style="float:left;" onmouseover="showThis('
                   + myThis[i].fields.left +','
                   + myThis[i].fields.right +',\''
                   + myThis[i].fields.title +'\')"></a><p style="float:left;width:130px;height:80px;"><b>'
                   + myThis[i].fields.title +'</b> '
                   + myThis[i].fields.description +'</p></div>'

You can spot the ' in the third field of showThis.

The double quote didn't work!

It is clear why, but it is also clear why we should stick to single quotes... I guess...

This case is a very simple HTML embedding, and the error was generated by a simple copy/paste from a 'double quoted' JavaScript code.

So to answer the question:

Try to use single quotes while within HTML. It might save a couple of debug issues...

Maybe the span element is hidden. If that's the case then use the innerHtml property:

By.css:

String kk = wd.findElement(By.cssSelector("#customSelect_3 span.selectLabel"))
              .getAttribute("innerHTML");

By.xpath:

String kk = wd.findElement(By.xpath(
                   "//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel')]"))
              .getAttribute("innerHTML");

"/.//" means "look under the selected element".

Be careful when you take the exception object or the traceback object out of the exception handler, since this causes circular references and gc.collect() will fail to collect. This appears to be of a particular problem in the ipython/jupyter notebook environment where the traceback object doesn't get cleared at the right time and even an explicit call to gc.collect() in finally section does nothing. And that's a huge problem if you have some huge objects that don't get their memory reclaimed because of that (e.g. CUDA out of memory exceptions that w/o this solution require a complete kernel restart to recover).

In general if you want to save the traceback object, you need to clear it from references to locals(), like so:

import sys, traceback, gc
type, val, tb = None, None, None
try:
    myfunc()
except:
    type, val, tb = sys.exc_info()
    traceback.clear_frames(tb)
# some cleanup code
gc.collect()
# and then use the tb:
if tb:
    raise type(val).with_traceback(tb)

In the case of jupyter notebook, you have to do that at the very least inside the exception handler:

try:
    myfunc()
except:
    type, val, tb = sys.exc_info()
    traceback.clear_frames(tb)
    raise type(val).with_traceback(tb)
finally:
    # cleanup code in here
    gc.collect()

Tested with python 3.7.

p.s. the problem with ipython or jupyter notebook env is that it has %tb magic which saves the traceback and makes it available at any point later. And as a result any locals() in all frames participating in the traceback will not be freed until the notebook exits or another exception will overwrite the previously stored backtrace. This is very problematic. It should not store the traceback w/o cleaning its frames. Fix submitted here.

I'm also having the exact same problem with both /usr/local/bin and /etc/sudoers on OSX Snow lepard.Even when i logged in as admin and tried to change the permissions via the terminal, it still says "Operation not permitted". And i did the following to get the permission of these folders.

From the terminal, I accessed /etc/sudoers file and using pico editor i added the following code: username ALL=(ALL) ALL Replace "username" with your MAC OS account name

Check this: How to maximize a plt.show() window using Python

The command is different depending on which backend you use. I find that this is the best way to make sure the saved pictures have the same scaling as what I view on my screen.

Since I use Canopy with the QT backend:

pylab.get_current_fig_manager().window.showMaximized()

I then call savefig() as required with an increased DPI per silvado's answer.

You have two ways:

Lets start by looking for a specific application in my laptop:

[root@pinky:~]# ps fax | grep mozilla
 3358 ?        S      0:00  \_ /bin/sh /usr/lib/firefox-3.5/run-mozilla.sh /usr/lib/firefox-3.5/firefox
16198 pts/2    S+     0:00              \_ grep mozilla

All examples now will look for PID 3358.

First way: Run "ps aux" and grep for the PID in the second column. In this example I look for firefox, and then for it's PID:

[root@pinky:~]# ps aux | awk '{print $2 }' | grep 3358
3358

So your code will be:

if [ ps aux | awk '{print $2 }' | grep -q $PID 2> /dev/null ]; then
    kill $PID 
fi

Second way: Just look for something in the /proc/$PID directory. I am using "exe" in this example, but you can use anything else.

[root@pinky:~]# ls -l /proc/3358/exe 
lrwxrwxrwx. 1 elcuco elcuco 0 2010-06-15 12:33 /proc/3358/exe -> /bin/bash

So your code will be:

if [ -f /proc/$PID/exe ]; then
    kill $PID 
fi

BTW: whats wrong with kill -9 $PID || true ?

EDIT:

After thinking about it for a few months.. (about 24...) the original idea I gave here is a nice hack, but highly unportable. While it teaches a few implementation details of Linux, it will fail to work on Mac, Solaris or *BSD. It may even fail on future Linux kernels. Please - use "ps" as described in other responses.

This uses twitter bootstrap 3.x with one css class to get labels to sit on top of the inputs. Here's a fiddle link, make sure to expand results panel wide enough to see effect.

HTML:

  <div class="row myform">
     <div class="col-md-12">
        <form name="myform" role="form" novalidate>
           <div class="form-group">
              <label class="control-label" for="fullName">Address Line</label>
              <input required type="text" name="addr" id="addr" class="form-control" placeholder="Address"/>
           </div>

           <div class="form-inline">
              <div class="form-group">
                 <label>State</label>
                 <input required type="text" name="state" id="state" class="form-control" placeholder="State"/>
              </div>

              <div class="form-group">
                 <label>ZIP</label>
                 <input required type="text" name="zip" id="zip" class="form-control" placeholder="Zip"/>
              </div>
           </div>

           <div class="form-group">
              <label class="control-label" for="country">Country</label>
              <input required type="text" name="country" id="country" class="form-control" placeholder="country"/>
           </div>
        </form>
     </div>
  </div>

CSS:

.myform input.form-control {
   display: block;  /* allows labels to sit on input when inline */
   margin-bottom: 15px; /* gives padding to bottom of inline inputs */
}

Use dict.setdefault():

>>> d = {1: 'one'}
>>> d.setdefault(1, '1')
'one'
>>> d    # d has not changed because the key already existed
{1: 'one'}
>>> d.setdefault(2, 'two')
'two'
>>> d
{1: 'one', 2: 'two'}

You need to add a dataType - http://api.jquery.com/jQuery.ajax/

$(document).ready(function() {
    $("#lesen").click(function() {
        $.ajax({
            url : "helloworld.txt",
            dataType: "text",
            success : function (data) {
                $(".text").html(data);
            }
        });
    });
}); 

You can use the code below:

a {
display: block;
width: 113px;
margin: auto; 
}

By setting, in my case, the link to display:block, it is easier to position the link.
This works the same when you use a <div> tag/class.
You can pick any width you want.

The best approach that I know is Eric's answer at: Get notified when UITableView has finished asking for data?

Update: To make it work I have to put these calls in -tableView:cellForRowAtIndexPath:

[tableView beginUpdates];
[tableView endUpdates];

You can use this:

myDropDown.Items.Remove(myDropDown.Items.FindByValue("TextToFind"));

As a workaround, go to sdk installation directory and perform the following steps:

• Navigate to system-images/android-19/default
• Move everything in there to system-images/android-19/

The directory structure should look like this:

And it should work!

My answer is based on this answer: How can I get the current contents of an element in webdriver just more like copy-paste.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get('http://www.w3c.org')
element = driver.find_element_by_name('q')
element.send_keys('hi mom')

element_text = element.text
element_attribute_value = element.get_attribute('value')

print (element)
print ('element.text: {0}'.format(element_text))
print ('element.get_attribute(\'value\'): {0}'.format(element_attribute_value))


element = driver.find_element_by_css_selector('.description.expand_description > p')
element_text = element.text
element_attribute_value = element.get_attribute('value')

print (element)
print ('element.text: {0}'.format(element_text))
print ('element.get_attribute(\'value\'): {0}'.format(element_attribute_value))
driver.quit()

Also a good example.....

struct point{int x,y;};
typedef struct point point_t;
typedef struct
{
    struct point ne,se,sw,nw;
}rect_t;
rect_t temp;


int main()
{
//rotate
    RotateRect(&temp);
    return 0;
}

void RotateRect(rect_t *givenRect)
{
    point_t temp_point;
    /*Copy struct data from struct to struct within a struct*/
    temp_point = givenRect->sw;
    givenRect->sw = givenRect->se;
    givenRect->se = givenRect->ne;
    givenRect->ne = givenRect->nw;
    givenRect->nw = temp_point;
}

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

You may also use math.log1p.

According to the official documentation :

math.log1p(x)

Return the natural logarithm of 1+x (base e). The result is calculated in a way which is accurate for x near zero.

You may convert back to the original value using math.expm1 which returns e raised to the power x, minus 1.

This is most efficient way i can think of as doesn't include Array.indexOf() or Array.lastIndexOf() which have complexity of O(n) and using inside any loop of complexity O(n) will make complete complexity O(n^2).

My first loop have complexity of O(n/2) or O((n/2) + 1), as complexity of search in hash is O(1). The second loop worst complexity when there's no duplicate in array is O(n) and best complexity when every element have a duplicate is O(n/2).

function duplicates(arr) {
  let duplicates = [],
      d = {},
      i = 0,
      j = arr.length - 1;

  // Complexity O(n/2)
  while (i <= j) {
    if (i === j)
      d[arr[i]] ? d[arr[i]] += 1 : d[arr[i]] = 1;  // Complexity O(1)
    else {
      d[arr[i]] ? d[arr[i]] += 1 : d[arr[i]] = 1;  // Complexity O(1)
      d[arr[j]] ? d[arr[j]] += 1 : d[arr[j]] = 1;  // Complexity O(1)
    }

    ++i;
    --j;
  }

  // Worst complexity O(n), best complexity O(n/2)
  for (let k in d) {
    if (d[k] > 1)
      duplicates.push(k);
  }

  return duplicates;

}

console.log(duplicates([5,6,4,9,2,3,5,3,4,1,5,4,9]));
console.log(duplicates([2,3,4,5,4,3,4]));
console.log(duplicates([4,5,2,9]));
console.log(duplicates([4,5,2,9,2,5,9,4]));

Swift 3

@IBOutlet weak var webview: UIWebView!
webview.loadRequest(URLRequest(url: URL(string: "https://www.yourvideo.com")!))

   mkdir($save_folder, 0777);
}

If this is a simple Java project, You essentially create a new project and give the location of the existing code. The project wizard will tell you that it will use existing sources.

Also, Eclipse 3.3.2 is ancient history, you guys should really upgrade. This is like using Visual Studio 5.

Since you can also input numbers as well as fixed type strings, the answer should actually be:

function isBlank(value) {
  return $.trim(value);
}

Did it!

Aside of the fix Alexandre kindly provide me, I had to create an Interface:

public interface ScrollViewListener {
    void onScrollChanged(ScrollViewExt scrollView, 
                         int x, int y, int oldx, int oldy);
}

Then, i had to override the OnScrollChanged method from ScrollView in my ScrollViewExt:

public class ScrollViewExt extends ScrollView {
    private ScrollViewListener scrollViewListener = null;
    public ScrollViewExt(Context context) {
        super(context);
    }

    public ScrollViewExt(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public ScrollViewExt(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public void setScrollViewListener(ScrollViewListener scrollViewListener) {
        this.scrollViewListener = scrollViewListener;
    }

    @Override
    protected void onScrollChanged(int l, int t, int oldl, int oldt) {
        super.onScrollChanged(l, t, oldl, oldt);
        if (scrollViewListener != null) {
            scrollViewListener.onScrollChanged(this, l, t, oldl, oldt);
        }
    }
}

Now, as Alexandre said, put the package name in the XML tag (my fault), make my Activity class implement the interface created before, and then, put it all together:

scroll = (ScrollViewExt) findViewById(R.id.scrollView1);
scroll.setScrollViewListener(this);

And in the method OnScrollChanged, from the interface...

@Override
public void onScrollChanged(ScrollViewExt scrollView, int x, int y, int oldx, int oldy) {
    // We take the last son in the scrollview
    View view = (View) scrollView.getChildAt(scrollView.getChildCount() - 1);
    int diff = (view.getBottom() - (scrollView.getHeight() + scrollView.getScrollY()));

    // if diff is zero, then the bottom has been reached
    if (diff == 0) {
        // do stuff
    }
}

And it worked!

Thank you very much for your help, Alexandre!

Maybe a better solution would be to add an extra column that is automatically set to 1 on each row. As soon as there is an element that is not null change it to a 0.

then

If(drEntitity.rows[i].coulmn[8] = 1)
{
   dtEntity.Rows.Add(drEntity);
}
 else
 {
   //don't add, will create a new one (drEntity = dtEntity.NewRow();)
 }

Following is simple example that may help you:

json_string = """
{
    "pk": 1, 
    "fa": "cc.ee", 
    "fb": {
        "fc": "", 
        "fd_id": "12345"
    }
}"""

import json
data = json.loads(json_string)
if data["fa"] == "cc.ee":
    data["fb"]["new_key"] = "cc.ee was present!"

print json.dumps(data)

The output for the above code will be:

{"pk": 1, "fb": {"new_key": "cc.ee was present!", "fd_id": "12345", 
 "fc": ""}, "fa": "cc.ee"}

Note that you can set the ident argument of dump to print it like so (for example,when using print json.dumps(data , indent=4)):

{
    "pk": 1, 
    "fb": {
        "new_key": "cc.ee was present!", 
        "fd_id": "12345", 
        "fc": ""
    }, 
    "fa": "cc.ee"
}

Some online API's work pretty well: ocr.space and Google Cloud Vision. Both of these are free, as long as you do less than 1000 OCR's per month. You can drag & drop an image to do a quick manual test to see how they perform for your images.

I find OCR.space easier to use (no messing around with nuget libraries), but, for my purpose, Google Cloud Vision provided slightly better results than OCR.space.

Google Cloud Vision example:

GoogleCredential cred = GoogleCredential.FromJson(json);
Channel channel = new Channel(ImageAnnotatorClient.DefaultEndpoint.Host, ImageAnnotatorClient.DefaultEndpoint.Port, cred.ToChannelCredentials());
ImageAnnotatorClient client = ImageAnnotatorClient.Create(channel);
Image image = Image.FromStream(stream);

EntityAnnotation googleOcrText = client.DetectText(image).First();
Console.Write(googleOcrText.Description);

OCR.space example:

string uri = $"https://api.ocr.space/parse/imageurl?apikey=helloworld&url={imageUri}";
string responseString = WebUtilities.DoGetRequest(uri);
OcrSpaceResult result = JsonConvert.DeserializeObject<OcrSpaceResult>(responseString);
if ((!result.IsErroredOnProcessing) && !String.IsNullOrEmpty(result.ParsedResults[0].ParsedText))
  return result.ParsedResults[0].ParsedText;

If you would like to use a formula, the TRIM function will do exactly what you're looking for:

+----+------------+---------------------+
|    |     A      |           B         |
+----+------------+---------------------+
| 1  | =TRIM(B1)  |  value to trim here |
+----+------------+---------------------+

So to do the whole column...
1) Insert a column
2) Insert TRIM function pointed at cell you are trying to correct.
3) Copy formula down the page
4) Copy inserted column
5) Paste as "Values"

Should be good to go from there...

git checkout <old-branch>                <-- switch back

! If the repo has more than one stash, see which one to apply to the new-branch:

git stash list  
  stash@{0}: WIP on ...  
  stash@{1}: WIP on ...

and inspect the individual stash by,

git stash show stash@{1}

Or inspect all stashes at once:

git stash list -p

Try it.

$data = array("a"=>1,"b"=>2,"c"=>4,"d"=>5); $maxKey = current(array_keys($data, max($data))); var_dump($maxKey);

Use ISNULL to overcome it.

Example:

SELECT (ISNULL(field1, '') + '' + ISNULL(field2, '')+ '' + ISNULL(field3, '')) FROM table1

This will then replace your NULL content with an empty string which will preserve the concatentation operation from evaluating as an overall NULL result.

You can analyze the core dump file using the "gdb" command.

 gdb - The GNU Debugger

 syntax:

 # gdb executable-file core-file

 example: # gdb out.txt core.xxx 

if
  ...
  # several checks
  ...
elif ((var1 > 65535) or ((var1 < 1024)) and (var1 != 80) and (var1 != 443)):
  # fail
else
  ...

You missed a parenthesis.

If you want to keep the changes and change the branch in a single line command

git stash && git checkout <branch_name> && git stash pop

It's declaring the string as nvarchar data type, rather than varchar

You may have seen Transact-SQL code that passes strings around using an N prefix. This denotes that the subsequent string is in Unicode (the N actually stands for National language character set). Which means that you are passing an NCHAR, NVARCHAR or NTEXT value, as opposed to CHAR, VARCHAR or TEXT.

To quote from Microsoft:

Prefix Unicode character string constants with the letter N. Without the N prefix, the string is converted to the default code page of the database. This default code page may not recognize certain characters.

If you want to know the difference between these two data types, see this SO post:

What is the difference between varchar and nvarchar?

If you have constant URL I recommend use simplified http-request built on apache http.

You can build your client as following:

private filan static HttpRequest<YourResponseType> httpRequest = 
                   HttpRequestBuilder.createGet(yourUri,YourResponseType)
                   .build();

public void send(){
    ResponseHendler<YourResponseType> rh = 
         httpRequest.execute(param1, value1, param2, value2);

    handler.ifSuccess(this::whenSuccess).otherwise(this::whenNotSuccess);
}

public void whenSuccess(ResponseHendler<YourResponseType> rh){
     rh.ifHasContent(content -> // your code);
}

public void whenSuccess(ResponseHendler<YourResponseType> rh){
   LOGGER.error("Status code: " + rh.getStatusCode() + ", Error msg: " + rh.getErrorText());
}

Note: There are many useful methods to manipulate your response.

ZEROFILL

This essentially means that if the integer value 23 is inserted into an INT column with the width of 8 then the rest of the available position will be automatically padded with zeros.

Hence

23

becomes:

00000023

This is a very belated answer to my own question, but it keep getting attention, so I feel I must address it. Most of these answers are correct and handle the job perfectly. However, it depends on the needs of the application. This answer will be used to describe two solutions to this problem.

Application

Service

A Service is an application component that can perform long-running operations in
the background and does not provide a user interface.

This wasn't a full description of either, but I left links to the docs for those who want to investigate more. Overall the Service is the better for the instance I needed - running a ServerSocket to my SPP device.

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

static void Main(string[] args)
{
    long blah = 20948230498204;
    Console.WriteLine(blah.ToString().Length);
}

On Visual Studio 2017, the shortcut is: Ctrl+´,S.

I'm looking into using SSTJ for FFTs in Java. It can redirect via JNI to FFTW if the library is available or will use a pure Java implementation if not.

This might be a little late, but did you try calling loadView()?

I combined everything here and for me it works:

public static void showKeyboardWithFocus(View v, Activity a) {
    try {
        v.requestFocus();
        InputMethodManager imm = (InputMethodManager) a.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
        a.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Method1: ADD_MONTHS

ADD_MONTHS(SYSDATE, -6)

Method 2: Interval

SYSDATE - interval '6' month

Note: if you want to do the operations from start of the current month always, TRUNC(SYSDATE,'MONTH') would give that. And it expects a Date datatype as input.

Sure, no problem:

foreach(object item in sequence)
{
    if (item == null) continue;
    foreach(PropertyInfo property in item.GetType().GetProperties())
    {
        // do something with the property
    }
}

Just adding a bit of extra information here in case someone has the same issue as me.

I use namespaces in my code and I had a class with a function that throws an Exception.

However my try/catch code in another class file was completely ignored and the normal PHP error for an uncatched exception was thrown.

Turned out I forgot to add "use \Exception;" at the top, adding that solved the error.

i using FF 16.0.2 and jquery 1.8.3, all the code in the answer didn't work.
I use code like this and work.

$("input[type=text]").focus().select();

Careful not to use the input function, unless you know what you're doing. Unlike raw_input, input will accept any python expression, so it's kinda like eval

For Apache HttpClient 4.5 or newer version:

    CloseableHttpClient httpclient = HttpClients.createDefault();
    HttpPost httpPost = new HttpPost("http://targethost/login");
    String JSON_STRING="";
    HttpEntity stringEntity = new StringEntity(JSON_STRING,ContentType.APPLICATION_JSON);
    httpPost.setEntity(stringEntity);
    CloseableHttpResponse response2 = httpclient.execute(httpPost);

Note:

1 in order to make the code compile, both httpclient package and httpcore package should be imported.

2 try-catch block has been ommitted.

Reference: appache official guide

the Commons HttpClient project is now end of life, and is no longer being developed. It has been replaced by the Apache HttpComponents project in its HttpClient and HttpCore modules

You need to use javascript to show the name of the choosed file, as written in the documentation: https://getbootstrap.com/docs/4.5/components/forms/#file-browser

Here you can find the solution: Bootstrap 4 File Input

Take a look to navbar documentation in:

Twitter Bootstrap

Simple example: Form with textbox and Search button.

If you write "name" into the textbox and submit form, it will brings you patients with "name" in table.

View:

@using (Ajax.BeginForm("GetPatients", "Patient", new AjaxOptions {//GetPatients is name of method in PatientController
    InsertionMode = InsertionMode.Replace, //target element(#patientList) will be replaced
    UpdateTargetId = "patientList",
    LoadingElementId = "loader" // div with .gif loader - that is shown when data are loading   
}))
{
    string patient_Name = "";
    @Html.EditorFor(x=>patient_Name) //text box with name and id, that it will pass to controller
    <input  type="submit" value="Search" />
}

@* ... *@
<div id="loader" class=" aletr" style="display:none">
    Loading...<img src="~/Images/ajax-loader.gif" />
</div>
@Html.Partial("_patientList") @* this is view with patient table. Same view you will return from controller *@

_patientList.cshtml:

@model IEnumerable<YourApp.Models.Patient>

<table id="patientList" >
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Number)
    </th>       
</tr>
@foreach (var patient in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => patient.Name)
    </td>
    <td>
        @Html.DisplayFor(modelItem => patient.Number)
    </td>
</tr>
}
</table>

Patient.cs

public class Patient
{
   public string Name { get; set; }
   public int Number{ get; set; }
}

PatientController.cs

public PartialViewResult GetPatients(string patient_Name="")
{
   var patients = yourDBcontext.Patients.Where(x=>x.Name.Contains(patient_Name))
   return PartialView("_patientList", patients);
}

And also as TSmith said in comments, don´t forget to install jQuery Unobtrusive Ajax library through NuGet.

One doesn't need to give id for the controller. It can simply called as following

angular.element(document.querySelector('[ng-controller="HeaderCtrl"]')).scope().myFunc()

Here HeaderCtrl is the controller name defined in your JS

From the Twitter FAQ:

Most integrations with the API will require you to identify your application to Twitter by way of an API key. On the Twitter platform, the term "API key" usually refers to what's called an OAuth consumer key. This string identifies your application when making requests to the API. In OAuth 1.0a, your "API keys" probably refer to the combination of this consumer key and the "consumer secret," a string that is used to securely "sign" your requests to Twitter.

A better solution is to set the doc width/height using the aspect ratio of your image.

I have experienced the same issue before. In my case, I needed to install php-mbstring extension on GoDaddy VPS server. None of above solutions did work for me.

What I've found is to install PHP extensions using WHM (Web Hosting Manager) of GoDaddy. Anyone who use GoDaddy VPS server can access this page with the following address.

http://{Your_Server_IP_Address}:2087

On this page, you can easily find Easy Apache software that can help you to install/upgrade php components and extensions. You can select currently installed profile and customize and then provision the profile. Everything with Easy Apache is explanatory.

I remember that I did very similar things for HostGator server, but I don't remember how actually I did for profile update.

Edit: When you have got the server which supports Web Hosting Manager, then you can add/update/remove php extensions on WHM. On godaddy servers, it's even recommended to update PHP ini settings on WHM.

You can use this working script:

/**
* @param {range} countRange Range to be evaluated
* @param {range} colorRef Cell with background color to be searched for in countRange
* @return {number}
* @customfunction
*/

function countColoredCells(countRange,colorRef) {
  var activeRange = SpreadsheetApp.getActiveRange();
  var activeSheet = activeRange.getSheet();
  var formula = activeRange.getFormula();

  var rangeA1Notation = formula.match(/\((.*)\,/).pop();
  var range = activeSheet.getRange(rangeA1Notation);
  var bg = range.getBackgrounds();
  var values = range.getValues();

  var colorCellA1Notation = formula.match(/\,(.*)\)/).pop();
  var colorCell = activeSheet.getRange(colorCellA1Notation);
  var color = colorCell.getBackground();

  var count = 0;

  for(var i=0;i<bg.length;i++)
    for(var j=0;j<bg[0].length;j++)
      if( bg[i][j] == color )
        count=count+1;
  return count;
};

Then call this function in your google sheets:

=countColoredCells(D5:D123,Z11)

A short summary from my humble knowledge:

There are some easy computational problems (like finding the shortest path between two points in a graph), which can be calculated pretty fast ( O(n^k), where n is the size of the input and k is a constant (in the case of graphs, it's the number of vertexes or edges)).

Other problems, like finding a path that crosses every vertex in a graph or getting the RSA private key from the public key is harder (O(e^n)).

But CS speak tells that the problem is that we cannot 'convert' a non-deterministic Turing-machine to a deterministic one, we can, however, transform non-deterministic finite automatons (like the regex parser) into deterministic ones (well, you can, but the run-time of the machine will take long). That is, we have to try every possible path (usually smart CS professors can exclude a few ones).

It's interesting because nobody even has any idea of the solution. Some say it's true, some say it's false, but there is no consensus. Another interesting thing is that a solution would be harmful for public/private key encryptions (like RSA). You could break them as easily as generating an RSA key is now.

And it's a pretty inspiring problem.

nvarchar(max) is what you want to be using. The biggest advantage is that you can use all the T-SQL string functions on this data type. This is not possible with ntext. I'm not aware of any real disadvantages.

Since my related question was removed by a righteous hand after I had killed the whole day searching how to beat the "macro not found or disabled" error, posting here the only syntax that worked for me (application.run didn't, no matter what I tried)

Set objExcel = CreateObject("Excel.Application")

' Didn't run this way from the Modules
'objExcel.Application.Run "c:\app\Book1.xlsm!Sub1"
' Didn't run this way either from the Sheet
'objExcel.Application.Run "c:\app\Book1.xlsm!Sheet1.Sub1"
' Nor did it run from a named Sheet
'objExcel.Application.Run "c:\app\Book1.xlsm!Named_Sheet.Sub1"

' Only ran like this (from the Module1)

Set objWorkbook = objExcel.Workbooks.Open("c:\app\Book1.xlsm")
objExcel.Run "Sub1"

It usually happens when the certificate does not match with the host name.

The solution would be to contact the host and ask it to fix its certificate.
Otherwise you can turn off cURL's verification of the certificate, use the -k (or --insecure) option.
Please note that as the option said, it is insecure. You shouldn't use this option because it allows man-in-the-middle attacks and defeats the purpose of HTTPS.

Haskell

foldl (+) 0 [1,2,3,4,5]

Python

reduce(lambda a,b: a+b, [1,2,3,4,5], 0)

Obviously, that is a trivial example to illustrate a point. In Python you would just do sum([1,2,3,4,5]) and even Haskell purists would generally prefer sum [1,2,3,4,5].

For non-trivial scenarios when there is no obvious convenience function, the idiomatic pythonic approach is to explicitly write out the for loop and use mutable variable assignment instead of using reduce or a fold.

That is not at all the functional style, but that is the "pythonic" way. Python is not designed for functional purists. See how Python favors exceptions for flow control to see how non-functional idiomatic python is.

Use Java script to change action url dynamically Works for me well

function chgAction( action_name )
{

 {% for data in sidebar_menu_data %}

     if( action_name== "ABC"){ document.forms.action = "/ABC/";
     }
     else if( action_name== "XYZ"){ document.forms.action = "/XYZ/";
     }

}

<form name="forms" method="post" action="<put default url>" onSubmit="return checkForm(this);">{% csrf_token %} 

Spring MockMvc now has direct support for JSON. So you just say:

.andExpect(content().json("{'message':'ok'}"));

and unlike string comparison, it will say something like "missing field xyz" or "message Expected 'ok' got 'nok'.

This method was introduced in Spring 4.1.

well the only thing that will work is

python -m pip install pip==

you can and should run it under IDE terminal (mine was pycharm)

What changes for C++11?

Aggregates

The standard definition of an aggregate has changed slightly, but it's still pretty much the same:

An aggregate is an array or a class (Clause 9) with no user-provided constructors (12.1), no brace-or-equal-initializers for non-static data members (9.2), no private or protected non-static data members (Clause 11), no base classes (Clause 10), and no virtual functions (10.3).

Ok, what changed?

1. Previously, an aggregate could have no user-declared constructors, but now it can't have user-provided constructors. Is there a difference? Yes, there is, because now you can declare constructors and default them:

   struct Aggregate {
       Aggregate() = default; // asks the compiler to generate the default implementation
   };
   

   This is still an aggregate because a constructor (or any special member function) that is defaulted on the first declaration is not user-provided.

2. Now an aggregate cannot have any brace-or-equal-initializers for non-static data members. What does this mean? Well, this is just because with this new standard, we can initialize members directly in the class like this:

   struct NotAggregate {
       int x = 5; // valid in C++11
       std::vector<int> s{1,2,3}; // also valid
   };
   

   Using this feature makes the class no longer an aggregate because it's basically equivalent to providing your own default constructor.

So, what is an aggregate didn't change much at all. It's still the same basic idea, adapted to the new features.

What about PODs?

PODs went through a lot of changes. Lots of previous rules about PODs were relaxed in this new standard, and the way the definition is provided in the standard was radically changed.

The idea of a POD is to capture basically two distinct properties:

1. It supports static initialization, and
2. Compiling a POD in C++ gives you the same memory layout as a struct compiled in C.

Because of this, the definition has been split into two distinct concepts: trivial classes and standard-layout classes, because these are more useful than POD. The standard now rarely uses the term POD, preferring the more specific trivial and standard-layout concepts.

The new definition basically says that a POD is a class that is both trivial and has standard-layout, and this property must hold recursively for all non-static data members:

A POD struct is a non-union class that is both a trivial class and a standard-layout class, and has no non-static data members of type non-POD struct, non-POD union (or array of such types). Similarly, a POD union is a union that is both a trivial class and a standard layout class, and has no non-static data members of type non-POD struct, non-POD union (or array of such types). A POD class is a class that is either a POD struct or a POD union.

Let's go over each of these two properties in detail separately.

Trivial classes

Trivial is the first property mentioned above: trivial classes support static initialization. If a class is trivially copyable (a superset of trivial classes), it is ok to copy its representation over the place with things like memcpy and expect the result to be the same.

The standard defines a trivial class as follows:

A trivially copyable class is a class that:

— has no non-trivial copy constructors (12.8),

— has no non-trivial move constructors (12.8),

— has no non-trivial copy assignment operators (13.5.3, 12.8),

— has no non-trivial move assignment operators (13.5.3, 12.8), and

— has a trivial destructor (12.4).

A trivial class is a class that has a trivial default constructor (12.1) and is trivially copyable.

[ Note: In particular, a trivially copyable or trivial class does not have virtual functions or virtual base classes.—end note ]

So, what are all those trivial and non-trivial things?

A copy/move constructor for class X is trivial if it is not user-provided and if

— class X has no virtual functions (10.3) and no virtual base classes (10.1), and

— the constructor selected to copy/move each direct base class subobject is trivial, and

— for each non-static data member of X that is of class type (or array thereof), the constructor selected to copy/move that member is trivial;

otherwise the copy/move constructor is non-trivial.

Basically this means that a copy or move constructor is trivial if it is not user-provided, the class has nothing virtual in it, and this property holds recursively for all the members of the class and for the base class.

The definition of a trivial copy/move assignment operator is very similar, simply replacing the word "constructor" with "assignment operator".

A trivial destructor also has a similar definition, with the added constraint that it can't be virtual.

And yet another similar rule exists for trivial default constructors, with the addition that a default constructor is not-trivial if the class has non-static data members with brace-or-equal-initializers, which we've seen above.

Here are some examples to clear everything up:

// empty classes are trivial
struct Trivial1 {};

// all special members are implicit
struct Trivial2 {
    int x;
};

struct Trivial3 : Trivial2 { // base class is trivial
    Trivial3() = default; // not a user-provided ctor
    int y;
};

struct Trivial4 {
public:
    int a;
private: // no restrictions on access modifiers
    int b;
};

struct Trivial5 {
    Trivial1 a;
    Trivial2 b;
    Trivial3 c;
    Trivial4 d;
};

struct Trivial6 {
    Trivial2 a[23];
};

struct Trivial7 {
    Trivial6 c;
    void f(); // it's okay to have non-virtual functions
};

struct Trivial8 {
     int x;
     static NonTrivial1 y; // no restrictions on static members
};

struct Trivial9 {
     Trivial9() = default; // not user-provided
      // a regular constructor is okay because we still have default ctor
     Trivial9(int x) : x(x) {};
     int x;
};

struct NonTrivial1 : Trivial3 {
    virtual void f(); // virtual members make non-trivial ctors
};

struct NonTrivial2 {
    NonTrivial2() : z(42) {} // user-provided ctor
    int z;
};

struct NonTrivial3 {
    NonTrivial3(); // user-provided ctor
    int w;
};
NonTrivial3::NonTrivial3() = default; // defaulted but not on first declaration
                                      // still counts as user-provided
struct NonTrivial5 {
    virtual ~NonTrivial5(); // virtual destructors are not trivial
};

Standard-layout

Standard-layout is the second property. The standard mentions that these are useful for communicating with other languages, and that's because a standard-layout class has the same memory layout of the equivalent C struct or union.

This is another property that must hold recursively for members and all base classes. And as usual, no virtual functions or virtual base classes are allowed. That would make the layout incompatible with C.

A relaxed rule here is that standard-layout classes must have all non-static data members with the same access control. Previously these had to be all public, but now you can make them private or protected, as long as they are all private or all protected.

When using inheritance, only one class in the whole inheritance tree can have non-static data members, and the first non-static data member cannot be of a base class type (this could break aliasing rules), otherwise, it's not a standard-layout class.

This is how the definition goes in the standard text:

A standard-layout class is a class that:

— has no non-static data members of type non-standard-layout class (or array of such types) or reference,

— has no virtual functions (10.3) and no virtual base classes (10.1),

— has the same access control (Clause 11) for all non-static data members,

— has no non-standard-layout base classes,

— either has no non-static data members in the most derived class and at most one base class with non-static data members, or has no base classes with non-static data members, and

— has no base classes of the same type as the first non-static data member.

A standard-layout struct is a standard-layout class defined with the class-key struct or the class-key class.

A standard-layout union is a standard-layout class defined with the class-key union.

[ Note: Standard-layout classes are useful for communicating with code written in other programming languages. Their layout is specified in 9.2.—end note ]

And let's see a few examples.

// empty classes have standard-layout
struct StandardLayout1 {};

struct StandardLayout2 {
    int x;
};

struct StandardLayout3 {
private: // both are private, so it's ok
    int x;
    int y;
};

struct StandardLayout4 : StandardLayout1 {
    int x;
    int y;

    void f(); // perfectly fine to have non-virtual functions
};

struct StandardLayout5 : StandardLayout1 {
    int x;
    StandardLayout1 y; // can have members of base type if they're not the first
};

struct StandardLayout6 : StandardLayout1, StandardLayout5 {
    // can use multiple inheritance as long only
    // one class in the hierarchy has non-static data members
};

struct StandardLayout7 {
    int x;
    int y;
    StandardLayout7(int x, int y) : x(x), y(y) {} // user-provided ctors are ok
};

struct StandardLayout8 {
public:
    StandardLayout8(int x) : x(x) {} // user-provided ctors are ok
// ok to have non-static data members and other members with different access
private:
    int x;
};

struct StandardLayout9 {
    int x;
    static NonStandardLayout1 y; // no restrictions on static members
};

struct NonStandardLayout1 {
    virtual f(); // cannot have virtual functions
};

struct NonStandardLayout2 {
    NonStandardLayout1 X; // has non-standard-layout member
};

struct NonStandardLayout3 : StandardLayout1 {
    StandardLayout1 x; // first member cannot be of the same type as base
};

struct NonStandardLayout4 : StandardLayout3 {
    int z; // more than one class has non-static data members
};

struct NonStandardLayout5 : NonStandardLayout3 {}; // has a non-standard-layout base class

Conclusion

With these new rules a lot more types can be PODs now. And even if a type is not POD, we can take advantage of some of the POD properties separately (if it is only one of trivial or standard-layout).

The standard library has traits to test these properties in the header <type_traits>:

template <typename T>
struct std::is_pod;
template <typename T>
struct std::is_trivial;
template <typename T>
struct std::is_trivially_copyable;
template <typename T>
struct std::is_standard_layout;

You can use jQuery to achieve this using simple $.get method. .html work like innerHtml and replace the content of your div.

$.get("/YourUrl", {},
      function (returnedHtml) {
      $("#here").html(returnedHtml);
});

And call this using javascript setInterval method.

There are plenty of ways to align with CSS, each one has it's benefits and disadvantages, you could test them all to check which one fits your case better: http://www.w3schools.com/css/css_align.asp

TIP: Always search using W3 as extra word, that will give you in first places the resources of the W3school website or the w3.org if there's any relevant.

Quoted from the javadoc;

This interface imposes a total ordering on the objects of each class that implements it. This ordering is referred to as the class's natural ordering, and the class's compareTo method is referred to as its natural comparison method.

Lists (and arrays) of objects that implement this interface can be sorted automatically by Collections.sort (and Arrays.sort). Objects that implement this interface can be used as keys in a sorted map or as elements in a sorted set, without the need to specify a comparator.

Edit: ..and made the important bit bold.

By definining the following alias (in ~/.gitconfig) you can easily temporarily disable the fileMode per git command:

[alias]
nfm = "!f(){ git -c core.fileMode=false $@; };f"

When this alias is prefixed to the git command, the file mode changes won't show up with commands that would otherwise show them. For example:

git nfm status

I had a similar issue with an integer that could be legitimately assigned 0 in Access VBA. None of the above solutions worked for me.

At first I just used a boolean var and IF statement:

Dim i as integer, bol as boolean
   If bol = false then
      i = ValueIWantToAssign
      bol = True
   End If

In my case, my integer variable assignment was within a for loop and another IF statement, so I ended up using "Exit For" instead as it was more concise.

Like so:

Dim i as integer
ForLoopStart
   If ConditionIsMet Then
      i = ValueIWantToAssign
   Exit For
   End If
ForLoopEnd

This is what worked for me:

• Close all Sql Server referencing apps.
• Open Services in Control Panel.
• Find the "SQL Server (SQLEXPRESS)" entry and select properties.
• Stop the service (all Sql Server services).
• Enter "-m" at the Start parameters" fields.
• Start the service (click on Start button on General Tab).
• Open a Command Prompt (right click, Run as administrator if needed).

• Enter the command:

  osql -S localhost\SQLEXPRESS -E

  (or change localhost to whatever your PC is called).

• At the prompt type the following commands:

  CREATE LOGIN my_Login_here WITH PASSWORD = 'my_Password_here'

  go

  sp_addsrvrolemember 'my_Login_here', 'sysadmin'

  go

  quit

• Stop the "SQL Server (SQLEXPRESS)" service.

• Remove the "-m" from the Start parameters field (if still there).

• Start the service.

• In Management Studio, use the login and password you just created. This should give it admin permission.

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

Jason,

This is how it works.

Localnamespace - java:comp/env is a local name space used by the application. The name that you use in it jdbc/db is just an alias. It does not refer to a physical resource.

During deployment this alias should be mapped to a physical resource (in your case a data source) that is defined on the WAS/WPS run time.

This is actually stored in ejb-bnd.xmi files. In the latest versions the XMIs are replaced with XML files. These files are referred to as the Binding files.

I don't see how you can compile a project with the C# compiler (or the VB compiler) and not have it balk at the wrong language for the compiler.

Keep your C# code in a separate project from your VB project. You can include these projects into the same solution.

Kotlin helper method to attach click to copy Texts on a TextView

Put this method somewhere in Util class. This method attach click listener on textview to Copy Content of textView to a clipText on click of that textView

/**
 * Param:  cliplabel, textview, context
 */
fun attachClickToCopyText(textView: TextView?, clipLabel: String, context: Context?) {
    if (textView != null && null != context) {
        textView.setOnClickListener {
            val clipboard = context.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
            val clip = ClipData.newPlainText(clipLabel, textView!!.text)
            clipboard.primaryClip = clip
            Snackbar.make(textView,
                    "Copied $clipLabel", Snackbar.LENGTH_LONG).show()
        }
    }

}

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

Use case:

 sesssionStorage.setObj(1,{date:Date.now(),action:'save firstObject'});
 sesssionStorage.setObj(2,{date:Date.now(),action:'save 2nd object'}); 
 //Query first object
  sesssionStorage.getObj(1)
  //Retrieve date created of 2nd object
  new Date(sesssionStorage.getObj(1).date)

API

Storage.prototype.setObj = function(key, obj) {

        return this.setItem(key, JSON.stringify(obj))
    };
    
    Storage.prototype.getObj = function(key) {
        return JSON.parse(this.getItem(key))
    };

The simplest solution would be a correlated sub select:

select
    A.*
from
    table_A A
where
    A.id in (
        select B.id from table_B B where B.tag = 'chair'
)

Alternatively you could join the tables and filter the rows you want:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

You should profile both and see which is faster on your dataset.

It's not really a question of what's more efficient.

The commands 'rsync', and 'cp' are not equivalent and achieve different goals.

1- rsync can preserve the time of creation of existing files. (using -a option)
2- rsync will run multiprocess and transfer using either local sockets or network sockets. (i.e. fork itself into multiple processes)
3- The multiprocessing, and threading will increase your throughput when copying large number of small files, and even with multiple larger files.

So bottom line is rsync is for large data, and cp is for smaller local copying. (MB to small GB range). When you start getting into multiple GB or in the TB range, go with rsync. And of course network copies, rsync all the way.

On the Git branch, run:

git branch -m old_name  new_name

This will modify the branch name on your local repository:

git push origin :old_name new_name

This will push the modified name to the remote and delete the old branch:

git push origin -u new_name

It sets the local branch to track the remote branch.

This solves the issue.

There is a hackish solution using OpenFileDialog where ValidateNames and CheckFileExists are both set to false and FileName is given a mock value to indicate that a directory is selected.

I say hack because it is confusing to users about how to select a folder. They need to be in the desired folder and then just press Open while file name says "Folder Selection."

This is based on Select file or folder from the same dialog by Denis Stankovski.

OpenFileDialog folderBrowser = new OpenFileDialog();
// Set validate names and check file exists to false otherwise windows will
// not let you select "Folder Selection."
folderBrowser.ValidateNames = false;
folderBrowser.CheckFileExists = false;
folderBrowser.CheckPathExists = true;
// Always default to Folder Selection.
folderBrowser.FileName = "Folder Selection.";
if (folderBrowser.ShowDialog() == DialogResult.OK)
{
    string folderPath = Path.GetDirectoryName(folderBrowser.FileName);
    // ...
}

^{Tip of the hat to @gniourf_gniourf for clearing up a fundamental misconception.}

This answer attempts to provide an overview of the existing answers and to discuss their subtleties and relative merits as well as to provide background information, especially with respect to portability.

Finding files that are executable can refer to two distinct use cases:

• user-centric: find files that are executable by the current user.
• file-centric: find files that have (one or more) executable permission bits set.

Note that in either scenario it may make sense to use find -L ... instead of just find ... in order to also find symlinks to executables.

Note that the simplest file-centric case - looking for executables with the executable permissions bit set for ALL three security principals (user, group, other) - will typically, but not necessarily yield the same results as the user-centric scenario - and it's important to understand the difference.

User-centric (-executable)

• The accepted answer commendably recommends -executable, IF GNU find is available.

  • GNU find comes with most Linux distros
    • By contrast, BSD-based platforms, including macOS, come with BSD find, which is less powerful.
  • As the scenario demands, -executable matches only files the current user can execute (there are edge cases.^[1]).

• The BSD find alternative offered by the accepted answer (-perm +111) answers a different, file-centric question (as the answer itself states).

  • Using just -perm to answer the user-centric question is impossible, because what is needed is to relate the file's user and group identity to the current user's, whereas -perm can only test the file's permissions.
    Using only POSIX find features, the question cannot be answered without involving external utilities.

  • Thus, the best -perm can do (by itself) is an approximation of -executable. Perhaps a closer approximation than -perm +111 is -perm -111, so as to find files that have the executable bit set for ALL security principals (user, group, other) - this strikes me as the typical real-world scenario. As a bonus, it also happens to be POSIX-compliant (use find -L to include symlinks, see farther below for an explanation):

    find . -type f -perm -111  # or: find . -type f -perm -a=x
    

• gniourf_gniourf's answer provides a true, portable equivalent of -executable, using -exec test -x {} \;, albeit at the expense of performance.

  • Combining -exec test -x {} \; with -perm +111 (i.e., files with at least one executable bit set) may help performance in that exec needn't be invoked for every file (the following uses the POSIX-compliant equivalent of BSD find -perm +111 / GNU find -perm /111; see farther below for an explanation):

    find . -type f \( -perm -u=x -o -perm -g=x -o -perm -o=x \) -exec test -x {} \; -print
    

File-centric (-perm)

• To answer file-centric questions, it is sufficient to use the POSIX-compliant -perm primary (known as a test in GNU find terminology).
  • -perm allows you to test for any file permissions, not just executability.
  • Permissions are specified as either octal or symbolic modes. Octal modes are octal numbers (e.g., 111), whereas symbolic modes are strings (e.g., a=x).
  • Symbolic modes identify the security principals as u (user), g (group) and o (other), or a to refer to all three. Permissions are expressed as x for executable, for instance, and assigned to principals using operators =, + and -; for a full discussion, including of octal modes, see the POSIX spec for the chmod utility.
  • In the context of find:
    • Prefixing a mode with - (e.g., -ug=x) means: match files that have all the permissions specified (but matching files may have additional permissions).
    • Having NO prefix (e.g. 755) means: match files that have this full, exact set of permissions.
    • Caveat: Both GNU find and BSD find implement an additional, nonstandard prefix with are-ANY-of-the-specified-permission-bits-set logic, but do so with incompatible syntax:
      • BSD find: +
      • GNU find: / ^[2]
    • Therefore, avoid these extensions, if your code must be portable.
• The examples below demonstrate portable answers to various file-centric questions.

File-centric command examples

Note:

• The following examples are POSIX-compliant, meaning they should work in any POSIX-compatible implementation, including GNU find and BSD find; specifically, this requires:
  • NOT using nonstandard mode prefixes + or /.
  • Using the POSIX forms of the logical-operator primaries:
    • ! for NOT (GNU find and BSD find also allow -not); note that \! is used in the examples so as to protect ! from shell history expansions
    • -a for AND (GNU find and BSD find also allow -and)
    • -o for OR (GNU find and BSD find also allow -or)
• The examples use symbolic modes, because they're easier to read and remember.
  • With mode prefix -, the = and + operators can be used interchangeably (e.g., -u=x is equivalent to -u+x - unless you apply -x later, but there's no point in doing that).
  • Use , to join partial modes; AND logic is implied; e.g., -u=x,g=x means that both the user and the group executable bit must be set.
  • Modes cannot themselves express negative matching in the sense of "match only if this bit is NOT set"; you must use a separate -perm expression with the NOT primary, !.
• Note that find's primaries (such as -print, or -perm; also known as actions and tests in GNU find) are implicitly joined with -a (logical AND), and that -o and possibly parentheses (escaped as \( and \) for the shell) are needed to implement OR logic.
• find -L ... instead of just find ... is used in order to also match symlinks to executables
  • -L instructs find to evaluate the targets of symlinks instead of the symlinks themselves; therefore, without -L, -type f would ignore symlinks altogether.

# Match files that have ALL executable bits set - for ALL 3 security
# principals (u (user), g (group), o (others)) and are therefore executable
# by *anyone*.
# This is the typical case, and applies to executables in _system_ locations
# (e.g., /bin) and user-installed executables in _shared_ locations
# (e.g., /usr/local/bin), for instance. 
find -L . -type f -perm -a=x  # -a=x is the same as -ugo=x

# The POSIX-compliant equivalent of `-perm +111` from the accepted answer:
# Match files that have ANY executable bit set.
# Note the need to group the permission tests using parentheses.
find -L . -type f \( -perm -u=x -o -perm -g=x -o -perm -o=x \)

# A somewhat contrived example to demonstrate the use of a multi-principial
# mode (comma-separated clauses) and negation:
# Match files that have _both_ the user and group executable bit set, while
# also _not_ having the other executable bit set.
find -L . -type f -perm -u=x,g=x  \! -perm -o=x

^{[1] Description of -executable from man find as of GNU find 4.4.2:}

Matches files which are executable and directories which are searchable (in a file name resolution sense). This takes into account access control lists and other permissions artefacts which the -perm test ignores. This test makes use of the access(2) system call, and so can be fooled by NFS servers which do UID mapping (or root-squashing), since many systems implement access(2) in the client's kernel and so cannot make use of the UID mapping information held on the server. Because this test is based only on the result of the access(2) system call, there is no guarantee that a file for which this test succeeds can actually be executed.

^{[2] GNU find versions older than 4.5.12 also allowed prefix +, but this was first deprecated and eventually removed, because combining + with symbolic modes yields likely yields unexpected results due to being interpreted as an exact permissions mask. If you (a) run on a version before 4.5.12 and (b) restrict yourself to octal modes only, you could get away with using + with both GNU find and BSD find, but it's not a good idea.}

you can change the size of an icon using the font size rather than setting the height and width of an icon. Here is how you do it:

<i class="fa fa-minus-square-o" style="font-size: 0.73em;"></i>

There are 4 ways to specify the dimensions of the icon.

px : give fixed pixels to your icon

em : dimensions with respect to your current font. Say ur current font is 12px then 1.5em will be 18px (12px + 6px).

pt : stands for points. Mostly used in print media

% : percentage. Refers to the size of the icon based on its original size.

A problem with answer 0 is that the enum binary values do not necessarily start at 0 and are not necessarily contiguous.

When I need this, I usually:

• pull the enum definition into my source
• edit it to get just the names
• do a macro to change the name to the case clause in the question, though typically on one line: case foo: return "foo";
• add the switch, default and other syntax to make it legal

<DataGridTextColumn Header="Quantity" Binding="{Binding Quantity}" >
  <DataGridTextColumn.ElementStyle>
    <Style TargetType="{x:Type TextBlock}">
       <Setter Property="HorizontalAlignment" Value="Right" />
    </Style>
  </DataGridTextColumn.ElementStyle>
</DataGridTextColumn>

To add to the accepted answer, I had a similar issue and solved it using a similar approach with the contrived example below. In this case I needed to log some parameters on componentWillUnmount and as described in the original question I didn't want it to log every time the params changed.

const componentWillUnmount = useRef(false)

// This is componentWillUnmount
useEffect(() => {
    return () => {
        componentWillUnmount.current = true
    }
}, [])

useEffect(() => {
    return () => {
        // This line only evaluates to true after the componentWillUnmount happens 
        if (componentWillUnmount.current) {
            console.log(params)
        }
    }

}, [params]) // This dependency guarantees that when the componentWillUnmount fires it will log the latest params

        "Data Source=C:\Documents and Settings\XXXXXX\My Documents\my_access_table.accdb"
    strSql = "SELECT Count(*) FROM mytable;"
    cn.Open strConnection
    Set rs = cn.Execute(strSql)
    MsgBox rs.Fields(0) & " rows in MyTable"

    rs.Close
    Set rs = Nothing
    cn.Close
    Set cn = Nothing

End Sub

Like Robert Nishihara mentioned, Apache Arrow makes this easy, specifically with the Plasma in-memory object store, which is what Ray is built on.

I made brain-plasma specifically for this reason - fast loading and reloading of big objects in a Flask app. It's a shared-memory object namespace for Apache Arrow-serializable objects, including pickle'd bytestrings generated by pickle.dumps(...).

The key difference with Apache Ray and Plasma is that it keeps track of object IDs for you. Any processes or threads or programs that are running on locally can share the variables' values by calling the name from any Brain object.

$ pip install brain-plasma

$ plasma_store -m 10000000 -s /tmp/plasma

from brain_plasma import Brain
brain = Brain(path='/tmp/plasma/)

brain['a'] = [1]*10000

brain['a']
# >>> [1,1,1,1,...]

One option is to give the <a> a display of inline-block and then apply text-align: center; on the containing block (remove the float as well):

div { 
    background: red;
    overflow: hidden; 
    text-align: center;
}

span a {
    background: #222;
    color: #fff;
    display: inline-block;
    /* float:left;  remove */
    margin: 10px 10px 0 0;
    padding: 5px 10px
}

Iterators are first choice over operator[]. C++11 provides std::begin(), std::end() functions.

As your code uses just std::vector, I can't say there is much difference in both codes, however, operator [] may not operate as you intend to. For example if you use map, operator[] will insert an element if not found.

Also, by using iterator your code becomes more portable between containers. You can switch containers from std::vector to std::list or other container freely without changing much if you use iterator such rule doesn't apply to operator[].

$ su - postgres
$ psql
$ \du; for see the user on db
select the user that do you want be superuser and:
$ ALTER USER "user" with superuser;

Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.

To get the file path from the user use this function:

Private Function get_user_specified_filepath() As String
    'or use the other code example here.
    Dim fd As Office.FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Please select the file."
    get_user_specified_filepath = fd.SelectedItems(1)
End Function

Then just open the file read only and assign it to a variable:

dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)

I found that pathlib module also supports this.

from pathlib import Path
>>> Path.home()
WindowsPath('C:/Users/XXX')

SO So So simple solution , go to c:/Users/user_name/.ssh/ and delete all pub / private key pairs , this way heroku will generate keys for you.

As MySql accepts the date in y-m-d format in date type column, you need to STR_TO_DATE function to convert the date into yyyy-mm-dd format for insertion in following way:

INSERT INTO table_name(today) 
VALUES(STR_TO_DATE('07-25-2012','%m-%d-%y'));  

Similary, if you want to select the date in different format other than Mysql format, you should try DATE_FORMAT function

SELECT DATE_FORMAT(today, '%m-%d-%y') from table_name; 

Well, to answer the immediate question:

>>> s = "http://www.domain.com/?s=some&two=20"

The rfind method returns the index of right-most substring:

>>> s.rfind("&")
29

You can take all elements up to a given index with the slicing operator:

>>> "foobar"[:4]
'foob'

Putting the two together:

>>> s[:s.rfind("&")]
'http://www.domain.com/?s=some'

If you are dealing with URLs in particular, you might want to use built-in libraries that deal with URLs. If, for example, you wanted to remove two from the above query string:

First, parse the URL as a whole:

>>> import urlparse, urllib
>>> parse_result = urlparse.urlsplit("http://www.domain.com/?s=some&two=20")
>>> parse_result
SplitResult(scheme='http', netloc='www.domain.com', path='/', query='s=some&two=20', fragment='')

Take out just the query string:

>>> query_s = parse_result.query
>>> query_s
's=some&two=20'

Turn it into a dict:

>>> query_d = urlparse.parse_qs(parse_result.query)
>>> query_d
{'s': ['some'], 'two': ['20']}
>>> query_d['s']
['some']
>>> query_d['two']
['20']

Remove the 'two' key from the dict:

>>> del query_d['two']
>>> query_d
{'s': ['some']}

Put it back into a query string:

>>> new_query_s = urllib.urlencode(query_d, True)
>>> new_query_s
's=some'

And now stitch the URL back together:

>>> result = urlparse.urlunsplit((
    parse_result.scheme, parse_result.netloc,
    parse_result.path, new_query_s, parse_result.fragment))
>>> result
'http://www.domain.com/?s=some'

The benefit of this is that you have more control over the URL. Like, if you always wanted to remove the two argument, even if it was put earlier in the query string ("two=20&s=some"), this would still do the right thing. It might be overkill depending on what you want to do.

String has a constructor that takes byte[] and charsetname as parameters :)

The HTML Tidy library is able to fix some malformed XML files. Running your feeds through that before passing them on to the parser may help.

If you want the file upload control to Limit the types of files user can upload on a button click then this is the way..

<script type="text/JavaScript">
<!-- Begin
function TestFileType( fileName, fileTypes ) {
if (!fileName) return;

dots = fileName.split(".")
//get the part AFTER the LAST period.
fileType = "." + dots[dots.length-1];

return (fileTypes.join(".").indexOf(fileType) != -1) ?
alert('That file is OK!') : 
alert("Please only upload files that end in types: \n\n" + (fileTypes.join(" .")) + "\n\nPlease select a new file and try again.");
}
// -->
</script>

You can then call the function from an event like the onClick of the above button, which looks like:

onClick="TestFileType(this.form.uploadfile.value, ['gif', 'jpg', 'png', 'jpeg']);"

You can change this to: PDF and XLS

You can see it implemented over here: Demo

You don't have any example code but I assume you want to do something like this?

@View({
directives: [NgClass],
styles: [`
    .${TodoModel.COMPLETED}  {
        text-decoration: line-through;
    }
    .${TodoModel.STARTED} {
        color: green;
    }
`],
template: `<div>
                <span [ng-class]="todo.status" >{{todo.title}}</span>
                <button (click)="todo.toggle()" >Toggle status</button>
            </div>`
})

You assign ng-class to a variable which is dynamic (a property of a model called TodoModel as you can guess).

todo.toggle() is changing the value of todo.status and there for the class of the input is changing.

This is an example for class name but actually you could do the same think for css properties.

I hope this is what you meant.

This example is taken for the great egghead tutorial here.

Add to .icons div {width:160px; height:130px;} will work out very nicely

Experienced the same error, for me it was caused because on my Mac I have changed the DocumentRoot to my users Sites directory.

To fix it, I ran the recursive command to ensure that the Apache service has read permissions.

sudo chmod -R 755 ~/Sites

Are you trying to protect the variables against modification? If so, then you can use a module pattern:

var CONFIG = (function() {
     var private = {
         'MY_CONST': '1',
         'ANOTHER_CONST': '2'
     };

     return {
        get: function(name) { return private[name]; }
    };
})();

alert('MY_CONST: ' + CONFIG.get('MY_CONST'));  // 1

CONFIG.MY_CONST = '2';
alert('MY_CONST: ' + CONFIG.get('MY_CONST'));  // 1

CONFIG.private.MY_CONST = '2';                 // error
alert('MY_CONST: ' + CONFIG.get('MY_CONST'));  // 1

Using this approach, the values cannot be modified. But, you have to use the get() method on CONFIG :(.

If you don't need to strictly protect the variables value, then just do as suggested and use a convention of ALL CAPS.

Take a look at this.

Change your query to:

SET @rank=0;
SELECT @rank:=@rank+1 AS rank, itemID, COUNT(*) as ordercount
  FROM orders
  GROUP BY itemID
  ORDER BY ordercount DESC;
SELECT @rank;

The last select is your count.

This is the way I got it working for me:

  Tasks:
  - name: checking if the file 1 exists
     stat:      
      path: /path/to/foo abc.xts
     register: stat_result

  - name: moving file 1
    command: mv /path/to/foo abc.xts /tmp
    when: stat_result.stat.exists == True

the playbook above, will check if file abc.xts exists before move the file to tmp folder.

Concerning whether to raise an exception or return None: it depends on the use case. Either can be Pythonic.

Look at Python's dict class for example. x[y] hooks into dict.__getitem__, and it raises a KeyError if key is not present. But the dict.get method returns the second argument (which is defaulted to None) if key is not present. They are both useful.

The most important thing to consider is to document that behaviour in the docstring, and make sure that your get_attr() method does what it says it does.

To address your other questions, use these conventions:

if foo:
    # For testing truthiness

if not foo:
    # For testing falsiness

if foo is None:
    # Testing .. Noneliness ?

if foo is not None:
    # Check explicitly avoids common bugs caused by empty sequences being false

Functions that return True or False should probably have a name that makes this obvious to improve code readability:

def is_running_on_windows():
    return os.name == 'nt'

In Python 3 you can "type-hint" that:

>>> def is_running_on_windows() -> bool:
...     return os.name == 'nt'
... 
>>> is_running_on_windows.__annotations__
{'return': bool}

My approach

    function file_format_size($bytes, $decimals = 2) {
  $unit_list = array('B', 'KB', 'MB', 'GB', 'PB');

  if ($bytes == 0) {
    return $bytes . ' ' . $unit_list[0];
  }

  $unit_count = count($unit_list);
  for ($i = $unit_count - 1; $i >= 0; $i--) {
    $power = $i * 10;
    if (($bytes >> $power) >= 1)
      return round($bytes / (1 << $power), $decimals) . ' ' . $unit_list[$i];
  }
}

I had the same issue just add this function to the open dialog options and it worked sharm

open: function(){
            var closeBtn = $('.ui-dialog-titlebar-close');
            closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
        },

and on close event you need to remove that

close: function () {
            var closeBtn = $('.ui-dialog-titlebar-close');
            closeBtn.html('');}

Complete example

<div id="deleteDialog" title="Confirm Delete">
 Can you confirm you want to delete this event?
</div> 

$("#deleteDialog").dialog({
                width: 400, height: 200,
                modal: true,
                open: function () {
                    var closeBtn = $('.ui-dialog-titlebar-close');
                    closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
                },
                close: function () {
                    var closeBtn = $('.ui-dialog-titlebar-close');
                    closeBtn.html('');
                },
                buttons: {
                    "Confirm": function () {
                        calendar.fullCalendar('removeEvents', event._id);
                        $(this).dialog("close");
                    },
                    "Cancel": function () {
                        $(this).dialog("close");
                    }
                }
            });

            $("#dialog").dialog("open");

I know this is somewhat older, but since the keywords "border inside" landed me directly here, I would like to share some findings that may be worth mentioning here. When I was adding a border on the hover state, i got the effects that OP is talking about. The border ads pixels to the dimension of the box which made it jumpy. There is two more ways one can deal with this that also work for IE7.

1) Have a border already attached to the element and simply change the color. This way the mathematics are already included.

div {
   width:100px;
   height:100px;
   background-color: #aaa;
   border: 2px solid #aaa; /* notice the solid */
}

div:hover {
   border: 2px dashed #666;
}

2 ) Compensate your border with a negative margin. This will still add the extra pixels, but the positioning of the element will not be jumpy on

div {
   width:100px;
   height:100px;
   background-color: #aaa;
}

div:hover {
  margin: -2px;
  border: 2px dashed #333;
}

Just for people looking to do this in batch files, this code is working:

FOR /R "C:\Users\jonathan\Desktop\test" %%f IN (*.jpg) DO REN "%%f" *.png

In this example all files with .jpg extensions in the C:\Users\jonathan\Desktop\test directory are changed to *.png.

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

While the previous answers are correct, some compilers have options to break the standard and use the smallest type that will contain all values.

Example with GCC (documentation in the GCC Manual):

enum ord {
    FIRST = 1,
    SECOND,
    THIRD
} __attribute__ ((__packed__));
STATIC_ASSERT( sizeof(enum ord) == 1 )

'htop' is best command for see which process is using how much RAM.....

nobr is too unreliable, use tables

<table>
      <tr>
          <td> something </td>
          <td> something </td>
      </tr>
</table>

It all goes on the same line, everything is level with eachother, and you have much more freedom if you want to change something later.

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

Have a look at CSS and HTML in depth you will figure this out. It just floating the boxes left and right and those boxes need to be inside a same div. http://www.w3schools.com/html/html_layout.asp might be a good resource.

String String_firstNumber = JOptionPane.showInputDialog("Input  Semisecond");
int Int_firstNumber = Integer.parseInt(firstNumber);

Now your Int_firstnumber contains integer value of String_fristNumber.

hope it helped

Even simpler, use _.values from underscore.js https://underscorejs.org/#values

Surprisingly, no one mentioned this alternative that uses only built-in bash commands:

i="$IFS";IFS='/';set -f;p=($PWD);set +f;IFS="$i";echo "${p[-1]}"

As an added bonus you can easily obtain the name of the parent directory with:

[ "${#p[@]}" -gt 1 ] && echo "${p[-2]}"

These will work on Bash 4.3-alpha or newer.

protected static bool CheckDate(DateTime date)
{
    if(new DateTime() == date)      
        return false;       
    else        
        return true;        
} 

Just use the FORMAT function (works on SQL Server 2012 or newer):

SELECT FORMAT(EmployeeID, '000000')
FROM dbo.RequestItems
WHERE ID=0 

Reference: http://msdn.microsoft.com/en-us/library/hh213505.aspx

.modal-dialog {
   position: absolute;
   left: calc(50vw - 300px);
}

where 300 px is a half of my dialog window width.

This is actually the only thing that worked for me.

If you want to listen to a native event on the root element of a component, you have to use the .native modifier for v-on, like following:

<template>
  <div id="app">
    <test v-on:click.native="testFunction"></test>
  </div>
</template>

or in shorthand, as suggested in comment, you can as well do:

<template>
  <div id="app">
    <test @click.native="testFunction"></test>
  </div>
</template>

You can loop through the select_obj.options. There's a #text method in each of the option object, which you can use to compare to what you want and set the selectedIndex of the select_obj.

Since no one else said it, the short-cut to compile (build) a C# app in Visual Studio Code (VSCode) is SHIFT+CTRL+B.

If you want to see the build errors (because they don't pop-up by default), the shortcut is SHIFT+CTRL+M.

(I know this question was asking for more than just the build shortcut. But I wanted to answer the question in the title, which wasn't directly answered by other answers/comments.)

//Update 2018, works//

Method1:

Download phpseclib v1 and use this code:

<?php
set_include_path(__DIR__ . '/phpseclib1.0.11');
include("Net/SSH2.php");

$key ="MyPassword";
  /* ### if using PrivateKey ### 
  include("Crypt/RSA.php");
  $key = new Crypt_RSA();
  $key->loadKey(file_get_contents('private-key.ppk'));
  */

$ssh = new Net_SSH2('www.example.com', 22);   // Domain or IP
if (!$ssh->login('your_username', $key))  exit('Login Failed');

echo $ssh->exec('pwd');
?>

or Method2:

Download newest phpseclib v2 (requires composer install at first):

<?php

set_include_path($path=__DIR__ . '/phpseclib-master/phpseclib');
include ($path.'/../vendor/autoload.php');

$loader = new \Composer\Autoload\ClassLoader();

use phpseclib\Net\SSH2;

$key ="MyPassword";
  /* ### if using PrivateKey ### 
  use phpseclib\Crypt\RSA;
  $key = new RSA();
  $key->load(file_get_contents('private-key.ppk'));
  */

$ssh = new SSH2('www.example.com', 22);   // Domain or IP
if (!$ssh->login('your_username', $key))   exit('Login Failed'); 

echo $ssh->exec('pwd');
?>

p.s. if you get "Connection timed out" then it's probably the issue of HOST/FIREWALL (local or remote) or like that, not a fault of script.

The solution for me was very simple (after 10 hours of searching). Above where your folders are there is a combobox that says "android" click it and choose "Project".

yes there is on-mouseover in angular2 instead of ng-Mouseover like in angular 1.x so you have to write this :-

<div on-mouseover='over()' style="height:100px; width:100px; background:#e2e2e2">hello mouseover</div>

over(){
    console.log("Mouseover called");
  }

As @Gunter Suggested in comment there is alternate of on-mouseover we can use this too. Some people prefer the on- prefix alternative, known as the canonical form.

Update

HTML Code -

<div (mouseover)='over()' (mouseout)='out()' style="height:100px; width:100px; background:#e2e2e2">hello mouseover</div>

Controller/.TS Code -

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';

  over(){
    console.log("Mouseover called");
  }

  out(){
    console.log("Mouseout called");
  }
}

Working Example

Some other Mouse events can be used in Angular -

(mouseenter)="myMethod()"
(mousedown)="myMethod()"
(mouseup)="myMethod()"

I guess something like this would do the job.

var option = document.createElement("option");
option.text = "Text";
option.value = "myvalue";
var select = document.getElementById("daySelect");
select.appendChild(option);

Here's the NoCache attribute proposed by mattytommo, simplified by using the information from Chris Moschini's answer:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public sealed class NoCacheAttribute : OutputCacheAttribute
{
    public NoCacheAttribute()
    {
        this.Duration = 0;
    }
}

If you want to know if it's an empty string use === instead of ==.

if(variable === "") {
}

This is because === will only return true if the values on both sides are of the same type, in this case a string.

for example: (false == "") will return true, and (false === "") will return false.

You will figure out that setOnPageChangeListener is deprecated, use addOnPageChangeListener, as below:

ViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
       if(position == 1){  // if you want the second page, for example
           //Your code here
       }
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
});

Like this, using .limit():

var q = models.Post.find({published: true}).sort('date', -1).limit(20);
q.execFind(function(err, posts) {
  // `posts` will be of length 20
});

The exception is threw here (In FragmentActivity):

@Override
public void onBackPressed() {
    if (!mFragments.getSupportFragmentManager().popBackStackImmediate()) {
        super.onBackPressed();
    }
}

In FragmentManager.popBackStatckImmediate(),FragmentManager.checkStateLoss() is called firstly. That's the cause of IllegalStateException. See the implementation below:

private void checkStateLoss() {
    if (mStateSaved) { // Boom!
        throw new IllegalStateException(
                "Can not perform this action after onSaveInstanceState");
    }
    if (mNoTransactionsBecause != null) {
        throw new IllegalStateException(
                "Can not perform this action inside of " + mNoTransactionsBecause);
    }
}

I solve this problem simply by using a flag to mark Activity's current status. Here's my solution:

public class MainActivity extends AppCompatActivity {
    /**
     * A flag that marks whether current Activity has saved its instance state
     */
    private boolean mHasSaveInstanceState;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        mHasSaveInstanceState = true;
        super.onSaveInstanceState(outState);
    }

    @Override
    protected void onResume() {
        super.onResume();
        mHasSaveInstanceState = false;
    }

    @Override
    public void onBackPressed() {
        if (!mHasSaveInstanceState) {
            // avoid FragmentManager.checkStateLoss()'s throwing IllegalStateException
            super.onBackPressed();
        }

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

Using a js file you can capture the following, that can be used in the codebehind as well:

<script type="text/javascript">
    alert('Server: ' + window.location.hostname);
    alert('Full path: ' + window.location.href);
    alert('Virtual path: ' + window.location.pathname);
    alert('HTTP path: ' + 
        window.location.href.replace(window.location.pathname, ''));    
</script>

You have to use the TO_NUMBER function:

select * from exception where exception_value = to_number('105')

You should check the EOF after reading from file.

fscanf_s                   // read from file
while(condition)           // check EOF
{
   fscanf_s               // read from file
}

A fine example found here. Powerlord got it right, below, for POST you need HttpURLConnection, instead.

Below is the code to do that,

    URL url = new URL(urlString);
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);
    conn.setRequestProperty ("Authorization", encodedCredentials);

    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

    writer.write(data);
    writer.flush();
    String line;
    BufferedReader reader = new BufferedReader(new 
                                     InputStreamReader(conn.getInputStream()));
    while ((line = reader.readLine()) != null) {
      System.out.println(line);
    }
    writer.close();
    reader.close();

Change URLConnection to HttpURLConnection, to make it POST request.

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestMethod("POST");

Suggestion (...in comments):

You might need to set these properties too,

conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded");
conn.setRequestProperty( "Accept", "*/*" );

The answer to this is very needed today because not everyone wants to use cURL to consume web services. Also PHP does allow for this using the following code

function get_info()
{
    $post_data = array(
        'test' => 'foobar',
        'okay' => 'yes',
        'number' => 2
    );

    // Send a request to example.com
    $result = $this->post_request('http://www.example.com/', $post_data);

    if ($result['status'] == 'ok'){

        // Print headers
        echo $result['header'];

        echo '<hr />';

        // print the result of the whole request:
        echo $result['content'];

    }
    else {
        echo 'A error occured: ' . $result['error'];
    }

}

function post_request($url, $data, $referer='') {

    // Convert the data array into URL Parameters like a=b&foo=bar etc.
    $data = http_build_query($data);

    // parse the given URL
    $url = parse_url($url);

    if ($url['scheme'] != 'http') {
        die('Error: Only HTTP request are supported !');
    }

    // extract host and path:
    $host = $url['host'];
    $path = $url['path'];

    // open a socket connection on port 80 - timeout: 30 sec
    $fp = fsockopen($host, 80, $errno, $errstr, 30);

    if ($fp){

        // send the request headers:
        fputs($fp, "POST $path HTTP/1.1\r\n");
        fputs($fp, "Host: $host\r\n");

        if ($referer != '')
            fputs($fp, "Referer: $referer\r\n");

        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: ". strlen($data) ."\r\n");
        fputs($fp, "Connection: close\r\n\r\n");
        fputs($fp, $data);

        $result = '';
        while(!feof($fp)) {
            // receive the results of the request
            $result .= fgets($fp, 128);
        }
    }
    else {
        return array(
            'status' => 'err',
            'error' => "$errstr ($errno)"
        );
    }

    // close the socket connection:
    fclose($fp);

    // split the result header from the content
    $result = explode("\r\n\r\n", $result, 2);

    $header = isset($result[0]) ? $result[0] : '';
    $content = isset($result[1]) ? $result[1] : '';

    // return as structured array:
    return array(
        'status' => 'ok',
        'header' => $header,
        'content' => $content);

}

A convenient function for saving plots is ggsave(), which can automatically guess the device type based on the file extension, and smooths over differences between devices. You save with a certain size and units like this:

ggsave("mtcars.png", width = 20, height = 20, units = "cm")

In R markdown, figure size can be specified by chunk:

```{r, fig.width=6, fig.height=4}  
plot(1:5)
```

Your diameter variable won't work because you're trying to store a String into a variable that will only accept a double. In order for it to work you will need to parse it

Ex:

diameter = Double.parseDouble(JOptionPane.showInputDialog("enter the diameter of a sphere.");
