From axios docs you have baseURL and url

baseURL will be prepended to url when making requests. So you can define baseURL as http://127.0.0.1:8000 and make your requests to /url

 // `url` is the server URL that will be used for the request
 url: '/user',

 // `baseURL` will be prepended to `url` unless `url` is absolute.
 // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
 // to methods of that instance.
 baseURL: 'https://some-domain.com/api/',

I had similar situation. I found that one of my config maps was duplicated. I had two configmaps for the same namespace. One had the correct namespace reference, the other was pointing to the wrong namespace.

I deleted and recreated the configmap with the correct file (or fixed file). I am only using one, and that seemed to make the particular cluster happier.

So I would check the files for any typos or duplicate items that could be causing conflict.

Change your subplot settings to:

plt.subplot(1, 2, 1)

...

plt.subplot(1, 2, 2)

The parameters for subplot are: number of rows, number of columns, and which subplot you're currently on. So 1, 2, 1 means "a 1-row, 2-column figure: go to the first subplot." Then 1, 2, 2 means "a 1-row, 2-column figure: go to the second subplot."

You currently are asking for a 2-row, 1-column (that is, one atop the other) layout. You need to ask for a 1-row, 2-column layout instead. When you do, the result will be:

In order to minimize the overlap of subplots, you might want to kick in a:

plt.tight_layout()

before the show. Yielding:

ValueErrors :In Python, a value is the information that is stored within a certain object. To encounter a ValueError in Python means that is a problem with the content of the object you tried to assign the value to.

in your case name,lastname and email 3 parameters are there but unpaidmembers only contain 2 of them.

name, lastname, email in unpaidMembers.items() so you should refer data or your code might be
lastname, email in unpaidMembers.items() or name, email in unpaidMembers.items()

Claiming that the C++ compiler can produce more optimal code than a competent assembly language programmer is a very bad mistake. And especially in this case. The human always can make the code better than the compiler can, and this particular situation is a good illustration of this claim.

The timing difference you're seeing is because the assembly code in the question is very far from optimal in the inner loops.

(The below code is 32-bit, but can be easily converted to 64-bit)

For example, the sequence function can be optimized to only 5 instructions:

    .seq:
        inc     esi                 ; counter
        lea     edx, [3*eax+1]      ; edx = 3*n+1
        shr     eax, 1              ; eax = n/2
        cmovc   eax, edx            ; if CF eax = edx
        jnz     .seq                ; jmp if n<>1

The whole code looks like:

include "%lib%/freshlib.inc"
@BinaryType console, compact
options.DebugMode = 1
include "%lib%/freshlib.asm"

start:
        InitializeAll
        mov ecx, 999999
        xor edi, edi        ; max
        xor ebx, ebx        ; max i

    .main_loop:

        xor     esi, esi
        mov     eax, ecx

    .seq:
        inc     esi                 ; counter
        lea     edx, [3*eax+1]      ; edx = 3*n+1
        shr     eax, 1              ; eax = n/2
        cmovc   eax, edx            ; if CF eax = edx
        jnz     .seq                ; jmp if n<>1

        cmp     edi, esi
        cmovb   edi, esi
        cmovb   ebx, ecx

        dec     ecx
        jnz     .main_loop

        OutputValue "Max sequence: ", edi, 10, -1
        OutputValue "Max index: ", ebx, 10, -1

        FinalizeAll
        stdcall TerminateAll, 0

In order to compile this code, FreshLib is needed.

In my tests, (1 GHz AMD A4-1200 processor), the above code is approximately four times faster than the C++ code from the question (when compiled with -O0: 430 ms vs. 1900 ms), and more than two times faster (430 ms vs. 830 ms) when the C++ code is compiled with -O3.

The output of both programs is the same: max sequence = 525 on i = 837799.

I found some issue about that kind of error

Issue no 2.

Your local server has two database server and those database server conflict. this conflict like this mysql server & xampp or lampp or wamp server. Please one of the database like mysql server because xampp or lampp server automatically install mysql server on this machine

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

There are a lot of great articles on how to manipulate objects in Javascript (whether using Node JS or a browser). I suggest here is a good place to start: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects

If anyone wondering how to proceed with models and stuff, see below

        var itemArr: [Dictionary<String, String>] = []
        for model in models {
              let object = ["param1": model.param1,
                            "param2": model.param2]
              itemArr.append(object as! [String : String])
        }

        let param = ["field1": someValue,
                     "field2": someValue,
                     "field3": itemArr] as [String : Any]

        let url: URLConvertible = "http://------"

        Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default)
            .responseJSON { response in
                self.isLoading = false
                switch response.result {
                case .success:
                    break
                case .failure:
                    break
                }
        }

Swift4 - Apple Solution "POST" and "Codable"

Uploading Data to a Website using request.httpmethod = "Post" and Codable Stucts:

@see: Listing 2 Configuring a URL request

let userlogin = User(username: username, password: password, deviceid:UIDevice.current.identifierForVendor!.uuidString)

    guard let uploadData = try? JSONEncoder().encode(userlogin) else {
        print("Error UploadData: ")
        return
    }

    let urlUser = URL(string: APPURL.apiURL)!

    var request = URLRequest(url: urlUser)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")

    var responseStatus = 0

    let task = URLSession.shared.uploadTask(with: request, from: uploadData) { data, response, error in
        if let error = error {
            let code = (error as NSError).code
            print("Error:\(code) : \(error.localizedDescription)")
            completion(code)
            return
        }  
      guard let response = response as? HTTPURLResponse else {
            print("Invalid response")
            return
        }
// do your response handling here ...

You have to fetch the whole data in the list and then do the iteration as it is a file and will become inefficient otherwise.

private static final Type REVIEW_TYPE = new TypeToken<List<Review>>() {
}.getType();
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
List<Review> data = gson.fromJson(reader, REVIEW_TYPE); // contains the whole reviews list
data.toScreen(); // prints to screen some values

The MySQL dependency should be like the following syntax in the pom.xml file.

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.21</version>
    </dependency>

Make sure the syntax, groupId, artifactId, Version has included in the dependancy.

It worked for me you can try your: Add this to VM options in Tomcat

-DdevBaseDir="C:\Your_Project_Dir_Path"

This should work.

$.ajax({
    type: 'get',
    url: '/public/index',
    dataType: 'script',
    data: data_send,
    success: function() {
        $('.skills_section').slick('reinit');
      }
});

Here too I can reproduce this problem with scrapy and psycopg2 (both require C++ compiling), even though I have Microsoft Visual C++ Compiler for Python 2.7 installed.

It has to be noted that I use virtualenv. From your post I'm not sure whether you do the same.

Anyway I tried to skip the activation of the virtual environment. Then both scrapy and psycopg2 installed fine.

My hypothesis: there is a conflict between this 2014 C++ compiler for Python and virtualenv. I do not know why nor how to solve it (and I'd be glad if someone can suggest a workaround).

All you need to do for that is a simple loop.
This doesn't handle testing for lower case, upper-case mismatch. If this isn't exactly what you are looking for, comment, and I can revise.

If you are planning to learn VBA. This is a great start.

TESTED:

Sub MatchAndColor()

Dim lastRow As Long
Dim sheetName As String

    sheetName = "Sheet1"            'Insert your sheet name here
    lastRow = Sheets(sheetName).Range("A" & Rows.Count).End(xlUp).Row

    For lRow = 2 To lastRow         'Loop through all rows

        If Sheets(sheetName).Cells(lRow, "A") = Sheets(sheetName).Cells(lRow, "B") Then
            Sheets(sheetName).Cells(lRow, "A").Interior.ColorIndex = 3  'Set Color to RED
        End If

    Next lRow

End Sub

You should make x and y numpy arrays, not lists:

x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,
              0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78])
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,
              0.478,0.335,0.365,0.424,0.390,0.585,0.511])

With this change, it produces the expect plot. If they are lists, m * x will not produce the result you expect, but an empty list. Note that m is anumpy.float64 scalar, not a standard Python float.

I actually consider this a bit dubious behavior of Numpy. In normal Python, multiplying a list with an integer just repeats the list:

In [42]: 2 * [1, 2, 3]
Out[42]: [1, 2, 3, 1, 2, 3]

while multiplying a list with a float gives an error (as I think it should):

In [43]: 1.5 * [1, 2, 3]
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-43-d710bb467cdd> in <module>()
----> 1 1.5 * [1, 2, 3]
TypeError: can't multiply sequence by non-int of type 'float'

The weird thing is that multiplying a Python list with a Numpy scalar apparently works:

In [45]: np.float64(0.5) * [1, 2, 3]
Out[45]: []

In [46]: np.float64(1.5) * [1, 2, 3]
Out[46]: [1, 2, 3]

In [47]: np.float64(2.5) * [1, 2, 3]
Out[47]: [1, 2, 3, 1, 2, 3]

So it seems that the float gets truncated to an int, after which you get the standard Python behavior of repeating the list, which is quite unexpected behavior. The best thing would have been to raise an error (so that you would have spotted the problem yourself instead of having to ask your question on Stackoverflow) or to just show the expected element-wise multiplication (in which your code would have just worked). Interestingly, addition between a list and a Numpy scalar does work:

In [69]: np.float64(0.123) + [1, 2, 3]
Out[69]: array([ 1.123,  2.123,  3.123])

Remove the redundant Hibernate Configuration

If you're using Spring Boot, you don't need to provide the JPA and Hibernate configuration explicitly, as Spring Boot can do that for you.

Add database configuration properties

In the application.properties Spring Boot configuration file, you have the add your database configuration properties:

spring.datasource.driverClassName = "org.postgresql.Driver
spring.datasource.url = jdbc:postgresql://localhost:5432/teste?charSet=LATIN1
spring.datasource.username = klebermo
spring.datasource.password = 123

Add Hibernate specific properties

And, in the same application.properties configuration file, you can also set custom Hibernate properties:

# Log SQL statements
spring.jpa.show-sql = false

# Hibernate ddl auto for generating the database schema
spring.jpa.hibernate.ddl-auto = create

# Hibernate database Dialect
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect

That's it!

I have written a complete article at Spring Boot JPA Multiple Data Sources Example. In this article, we will learn how to configure multiple data sources and connect to multiple databases in a typical Spring Boot web application. We will use Spring Boot 2.0.5, JPA, Hibernate 5, Thymeleaf and H2 database to build a simple Spring Boot multiple data sources web application.

When you use @DataJpaTest you need to load classes using @Import explicitly. It wouldn't load you for auto.

It looks like you're having a permissions error, based on this message in your output: error: could not create '/lib/python2.7/site-packages/lxml': Permission denied.

One thing you can try is doing a user install of the package with pip install lxml --user. For more information on how that works, check out this StackOverflow answer. (Thanks to Ishaan Taylor for the suggestion)

You can also run pip install as a superuser with sudo pip install lxml but it is not generally a good idea because it can cause issues with your system-level packages.

matrix multiplication, see the following example:

> A <- matrix (c(1,3,4, 5,8,9, 1,3,3), 3,3)
> A
     [,1] [,2] [,3]
[1,]    1    5    1
[2,]    3    8    3
[3,]    4    9    3
> 
> B <- matrix (c(2,4,5, 8,9,2, 3,4,5), 3,3)
> 
> B
     [,1] [,2] [,3]
[1,]    2    8    3
[2,]    4    9    4
[3,]    5    2    5
> 
> 
> A %*% B
     [,1] [,2] [,3]
[1,]   27   55   28
[2,]   53  102   56
[3,]   59  119   63

> B %*% A
     [,1] [,2] [,3]
[1,]   38  101   35
[2,]   47  128   43
[3,]   31   86   26

Also see:

http://en.wikipedia.org/wiki/Matrix_multiplication

If this does not follow the size of matrix rule you will get the error:

> A <- matrix(c(1,2,3,4,5,6), 3,2)
    > A
     [,1] [,2]
[1,]    1    4

    Error in A %*% B : non-conformable arguments

I had the same problem and got it resolved by deleting .m2 maven repo (C:\Users\user\ .m2)

Make sure, following jar file included in your class path and lib folder.

spring-core-3.0.5.RELEASE.jar

if you are using maven, make sure you have included dependency for spring-core-3xxxxx.jar file

<dependency>
 <groupId>org.springframework</groupId>
 <artifactId>spring-core</artifactId>
 <version>${org.springframework.version}</version>
</dependency>

Note : Replace ${org.springframework.version} with version number.

If you are doing form validation such as

type="submit" onsubmit="return validateForm(this)"

validateForm = function(form) {
if ($('input#company').val() === "" || $('input#company').val() === "Company")  {
        $('input#company').val("Company").css('color','red'); finalReturn = false; 
        $('input#company').on('mouseover',(function() { 
            $('input#company').val("").css('color','black'); 
            $('input#company').off('mouseover');
            finalReturn = true; 
        }));
    } 

    return finalReturn; 
}

Double check you are returning true. This seems simple but I had

var finalReturn = false;

When the form was correct it was not being corrected by validateForm and so not being submitted as finalReturn was still initialized to false instead of true. By the way, above code works nicely with address, city, state and so on.

Previous answers are correct but here is one more way of doing this and some tips:

Option #1 Go to you Jenkins job and search for "add build step" and then just copy and paste your script there

Option #2 Go to Jenkins and do the same again "add build step" but this time put the fully qualified path for your script in there example : ./usr/somewhere/helloWorld.sh

things to watch for /tips:

• Environment variables, if your job is running at the same time then you need to worry about concurrency issues. One job may be setting the value of environment variables and the next may use the value or take some action based on that incorrectly.
• Make sure all paths are fully qualified
• Think about logging /var/log or somewhere so you would also have something to go to on the server (optional)
• thing about space issue and permissions, running out of space and permission issues are very common in linux environment
• Alerting and make sure your script/job fails the jenkin jobs when your script fails

Alternatively if you want to persist in using the DocumentType class. Then you could just add the following annotation on top of your DocumentType class.

    @XmlRootElement(name="document")

Note: the String value "document" refers to the name of the root tag of the xml message.

Correct way shall be to autowire AbstractManager, as Max suggested, but this should work fine as well.

@Autowired
@Qualifier(value="mailService")
public MailManager mailManager;

and

@Component("mailService")
@Transactional
public class MailManager extends AbstractManager {
}

Using pip with git+ to clone a repository can be extremely slow (test with https://github.com/django/django@stable/1.6.x for example, it will take a few minutes). The fastest thing I've found, which works with GitHub and BitBucket, is:

pip install https://github.com/user/repository/archive/branch.zip

which becomes for Django master:

pip install https://github.com/django/django/archive/master.zip

for Django stable/1.7.x:

pip install https://github.com/django/django/archive/stable/1.7.x.zip

With BitBucket it's about the same predictable pattern:

pip install https://bitbucket.org/izi/django-admin-tools/get/default.zip

Here, the master branch is generally named default. This will make your requirements.txt installing much faster.

Some other answers mention variations required when placing the package to be installed into your requirements.txt. Note that with this archive syntax, the leading -e and trailing #egg=blah-blah are not required, and you can just simply paste the URL, so your requirements.txt looks like:

https://github.com/user/repository/archive/branch.zip

background-size: contain; 

suits me

For MySql take in mind that it's not a good idea to write camelcase. For example if the schema is like that:

CREATE TABLE IF NOT EXISTS `task`(
    `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
    `teaching_hours` DECIMAL(5,2) DEFAULT NULL,
    `isActive` BOOLEAN DEFAULT FALSE,
    `is_validated` BOOLEAN DEFAULT FALSE,
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

You must be very careful cause isActive column will translate to isactive. So in your Entity class is should be like this:

 @Basic
 @Column(name = "isactive", nullable = true)
 public boolean isActive() {
     return isActive;
 }
 public void setActive(boolean active) {
     isActive = active;
 }

That was my problem at least that got me your error

This has nothing to do with MySql which is case insensitive, but rather is a naming strategy that spring will use to translate your tables. For more refer to this post

From the manual:

Possible values for the parameter timeout: … x set timeout to x seconds

and

readlines(sizehint=None, eol='\n') Read a list of lines, until timeout. sizehint is ignored and only present for API compatibility with built-in File objects.

Note that this function only returns on a timeout.

So your readlines will return at most every 2 seconds. Use read() as Tim suggested.

Yup, this is possible of course. Here are several examples.

-- one way to do this
DECLARE @Cnt int

SELECT @Cnt = COUNT(SomeColumn)
FROM TableName
GROUP BY SomeColumn

-- another way to do the same thing
DECLARE @StreetName nvarchar(100)
SET @StreetName = (SELECT Street_Name from Streets where Street_ID = 123)

-- Assign values to several variables at once
DECLARE @val1 nvarchar(20)
DECLARE @val2 int
DECLARE @val3 datetime
DECLARE @val4 uniqueidentifier
DECLARE @val5 double

SELECT @val1 = TextColumn,
@val2 = IntColumn,
@val3 = DateColumn,
@val4 = GuidColumn,
@val5 = DoubleColumn
FROM SomeTable

You need upper case property names in your structs in order to be used by the json packages.

Upper case property names are exported properties. Lower case property names are not exported.

You also need to pass the your data object by reference (&data).

package main

import "fmt"

You should analyze your style.css file, possibly using Developer Tools in your favorite browser, to see which rule sets font size on the element in a manner that overrides the one in a style attribute. Apparently, it has to be one using the !important specifier, which generally indicates poor logic and structure in styling.

Primarily, modify the style.css file so that it does not use !important. Failing this, add !important to the rule in style attribute. But you should aim at reducing the use of !important, not increasing it.

I will submit the basis for an alternate solution. It is not specific to a Tk progress bar per se, but it can certainly be implemented very easily for that.

Here are some classes that allow you to run other tasks in the background of Tk, update the Tk controls when desired, and not lock up the gui!

Here's class TkRepeatingTask and BackgroundTask:

import threading

class TkRepeatingTask():

    def __init__( self, tkRoot, taskFuncPointer, freqencyMillis ):
        self.__tk_   = tkRoot
        self.__func_ = taskFuncPointer        
        self.__freq_ = freqencyMillis
        self.__isRunning_ = False

    def isRunning( self ) : return self.__isRunning_ 

    def start( self ) : 
        self.__isRunning_ = True
        self.__onTimer()

    def stop( self ) : self.__isRunning_ = False

    def __onTimer( self ): 
        if self.__isRunning_ :
            self.__func_() 
            self.__tk_.after( self.__freq_, self.__onTimer )

class BackgroundTask():

    def __init__( self, taskFuncPointer ):
        self.__taskFuncPointer_ = taskFuncPointer
        self.__workerThread_ = None
        self.__isRunning_ = False

    def taskFuncPointer( self ) : return self.__taskFuncPointer_

    def isRunning( self ) : 
        return self.__isRunning_ and self.__workerThread_.isAlive()

    def start( self ): 
        if not self.__isRunning_ :
            self.__isRunning_ = True
            self.__workerThread_ = self.WorkerThread( self )
            self.__workerThread_.start()

    def stop( self ) : self.__isRunning_ = False

    class WorkerThread( threading.Thread ):
        def __init__( self, bgTask ):      
            threading.Thread.__init__( self )
            self.__bgTask_ = bgTask

        def run( self ):
            try :
                self.__bgTask_.taskFuncPointer()( self.__bgTask_.isRunning )
            except Exception as e: print repr(e)
            self.__bgTask_.stop()

Here's a Tk test which demos the use of these. Just append this to the bottom of the module with those classes in it if you want to see the demo in action:

Two import points I'll stress about BackgroundTask:

1) The function you run in the background task needs to take a function pointer it will both invoke and respect, which allows the task to be cancelled mid way through - if possible.

2) You need to make sure the background task is stopped when you exit your application. That thread will still run even if your gui is closed if you don't address that!

There's no way to write a safe application where you need to know whether a channel is open without interacting with it.

The best way to do what you're wanting to do is with two channels -- one for the work and one to indicate a desire to change state (as well as the completion of that state change if that's important).

Channels are cheap. Complex design overloading semantics isn't.

[also]

<-time.After(1e9)

is a really confusing and non-obvious way to write

time.Sleep(time.Second)

Keep things simple and everyone (including you) can understand them.

Convert the text view to an image, and the scale the image within the boundaries.

Here's an example on how to convert a view to an Image: Converting a view to Bitmap without displaying it in Android?

The problem is, your text will not be selectable, but it should do the trick. I haven't tried it, so I'm not sure how it would look (because of the scaling).

Error message suggests that the client has closed the connection while the server is still trying to write out a response.

Refer to this link for more details:

https://markhneedham.com/blog/2014/01/27/neo4j-org-eclipse-jetty-io-eofexception-caused-by-java-io-ioexception-broken-pipe/

I made this work in this way:

<button class="btn" ng-click='toggleClass($event)'>button one</button>
<button class="btn" ng-click='toggleClass($event)'>button two</button>

in your controller:

$scope.toggleClass = function (event) {
    $(event.target).toggleClass('active');
}

You cannot animate two things (like zoom in and go to my location) in one google map?

From a coding standpoint, you would do them sequentially:

    CameraUpdate center=
        CameraUpdateFactory.newLatLng(new LatLng(40.76793169992044,
                                                 -73.98180484771729));
    CameraUpdate zoom=CameraUpdateFactory.zoomTo(15);

    map.moveCamera(center);
    map.animateCamera(zoom);

Here, I move the camera first, then animate the camera, though both could be animateCamera() calls. Whether GoogleMap consolidates these into a single event, I can't say, as it goes by too fast. :-)

Here is the sample project from which I pulled the above code.

Sorry, this answer is flawed. See Rob's answer for a way to truly do this in one shot, by creating a CameraPosition and then creating a CameraUpdate from that CameraPosition.

As a beginner who stumbled across this thread, I'd like to add a python-for-dummies adaptation of abevieiramota's very neat answer (because I'm at the level that I had to look up 'ravel' to work out what their code was doing):

import numpy as np
import matplotlib.pyplot as plt

fig, ((ax1,ax2,ax3),(ax4,ax5,ax6)) = plt.subplots(2,3)

axlist = [ax1,ax2,ax3,ax4,ax5,ax6]

first = ax1.imshow(np.random.random((10,10)), vmin=0, vmax=1)
third = ax3.imshow(np.random.random((12,12)), vmin=0, vmax=1)

fig.colorbar(first, ax=axlist)

plt.show()

Much less pythonic, much easier for noobs like me to see what's actually happening here.

Thought I'd share this code. It's fairly simple, but effective. It parses comma-separated files with parenthesis. You can easily modify it to suit your needs.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>


int main(int argc, char *argv[])
{
  //argv[1] path to csv file
  //argv[2] number of lines to skip
  //argv[3] length of longest value (in characters)

  FILE *pfinput;
  unsigned int nSkipLines, currentLine, lenLongestValue;
  char *pTempValHolder;
  int c;
  unsigned int vcpm; //value character marker
  int QuotationOnOff; //0 - off, 1 - on

  nSkipLines = atoi(argv[2]);
  lenLongestValue = atoi(argv[3]);

  pTempValHolder = (char*)malloc(lenLongestValue);  

  if( pfinput = fopen(argv[1],"r") ) {

    rewind(pfinput);

    currentLine = 1;
    vcpm = 0;
    QuotationOnOff = 0;

    //currentLine > nSkipLines condition skips ignores first argv[2] lines
    while( (c = fgetc(pfinput)) != EOF)
    {
       switch(c)
       {
          case ',':
            if(!QuotationOnOff && currentLine > nSkipLines) 
            {
              pTempValHolder[vcpm] = '\0';
              printf("%s,",pTempValHolder);
              vcpm = 0;
            }
            break;

            {
              pTempValHolder[vcpm] = '\0';
              printf("%s\n",pTempValHolder);
              vcpm = 0;
            }
            currentLine++;
            break;
          case '\"':
            if(currentLine > nSkipLines)

                pTempValHolder[vcpm] = c;
                vcpm++;
              } else {
                QuotationOnOff = 0;
                pTempValHolder[vcpm] = c;
                vcpm++;
              }
            }
            break;
          default:
            if(currentLine > nSkipLines)
            {
              pTempValHolder[vcpm] = c;
              vcpm++;
            }
            break;
       }
    }

    fclose(pfinput); 
    free(pTempValHolder);

Recently I used an AS3 engine: PushButton (now is dead, but it's still functional and you could use something else) to do this job. To make it works with Android and iOS, the project was compiled in AIR for both platforms and everything worked with no performance damage. Since Flash Builder is kinda expensive ($249), you could use FlashDevelop (there is some tutorials to compile in AIR with it).

Flash could be an option since is very easy to learn.

@vimal answer did not provide solution for me. It seems the orientation is not the current orientation, but from previous orientation. To fix it, I use [[UIDevice currentDevice] orientation]

- (void)orientationChanged:(NSNotification *)notification{
    [self adjustViewsForOrientation:[[UIDevice currentDevice] orientation]];
}

Then

- (void) adjustViewsForOrientation:(UIDeviceOrientation) orientation { ... }

With this code I get the current orientation position.

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

You have to load the url helper to access that function. Either you add

$this->load->helper('url');

somewhere in your controller.

Alternately, to have it be loaded automatically everywhere, make sure the line in application/config/autoload.php that looks like

$autoload['helper'] = array('url');

has 'url' in that array (as shown above).

You may find that gnuplot's for loops are useful in this case, if you adjust your filenames or graph titles appropriately.

e.g.

filenames = "first second third fourth fifth"
plot for [file in filenames] file."dat" using 1:2 with lines

and

filename(n) = sprintf("file_%d", n)
plot for [i=1:10] filename(i) using 1:2 with lines

Please make sure that your applicationContext.xml file is loaded by specifying it in your web.xml file:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

It looks like your Spring component scan Base is missing UserServiceImpl

<context:component-scan base-package="org.assessme.com.controller." />

Multiple things can cause this, I didn't bother to check your entire repository, so I'm going out on a limb here.

First off, you could be missing an annotation (@Service or @Component) from the implementation of com.example.my.services.user.UserService, if you're using annotations for configuration. If you're using (only) xml, you're probably missing the <bean> -definition for the UserService-implementation.

If you're using annotations and the implementation is annotated correctly, check that the package where the implementation is located in is scanned (check your <context:component-scan base-package= -value).

set this jquery min js

script src="http://code.jquery.com/jquery-1.10.1.min.js"

in wp-admin/admin-header.php

I struggled like mad, but this is actually the right answer. For what it is worth, what I missed was is this:

1. As others say, one can't create the CustomUI ribbon with VBA, however, you don't need to!
2. The idea is you create your xml Ribbon code using Excel's File > Options > Customize Ribbon, and then export the Ribbon to a .customUI file (it's just a txt file, with xml in it)
3. Now comes the trick: you can include the .customUI code in your .xlsm file using the MS tool they refer to here, by copying the code from the .customUI file
4. Once it is included in the .xlsm file, every time you open it, the ribbon you defined is added to the user's ribbon - but do use < ribbon startFromScratch="false" > or you lose the rest of the ribbon. On exit-ing the workbook, the ribbon is removed.
5. From here on it is simple, create your ribbon, copy the xml code that is specific to your ribbon from the .customUI file, and place it in a wrapper as shown above (...< tabs> your xml < /tabs...)

By the way the page that explains it on Ron's site is now at http://www.rondebruin.nl/win/s2/win002.htm

And here is his example on how you enable /disable buttons on the Ribbon http://www.rondebruin.nl/win/s2/win013.htm

For other xml examples of ribbons please also see http://msdn.microsoft.com/en-us/library/office/aa338202%28v=office.12%29.aspx

I tried to change target sdk to 13 but does not works!! then when I changed compileSdkVersion 13 to compileSdkVersion 14 is compiled successfully :)

NOTE: I Work with Android Studio not Eclipse

There is another library with much cleaner API and type-safe data. https://github.com/kodart/Httpzoid

Here is a simple usage example

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .execute();

Or more complex with callbacks

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .handler(new ResponseHandler<Void>() {
        @Override
        public void success(Void ignore, HttpResponse response) {
        }

        @Override
        public void error(String message, HttpResponse response) {
        }

        @Override
        public void failure(NetworkError error) {
        }

        @Override
        public void complete() {
        }
    }).execute();

It is fresh new, but looks very promising.

Instead of using a UIView, as @ImreKelényi suggests, you can use a CALayer:

// Add a bottomBorder.
CALayer *bottomBorder = [CALayer layer];

bottomBorder.frame = CGRectMake(0.0f, 43.0f, toScrollView.frame.size.width, 1.0f);

bottomBorder.backgroundColor = [UIColor colorWithWhite:0.8f 
                                                 alpha:1.0f].CGColor;

[toScrollView.layer addSublayer:bottomBorder];

If a class defines virtual methods outside that class, then g++ generates the vtable only in the object file that contains the outside-of-class definition of the virtual method that was declared first:

//test.h
struct str
{
   virtual void f();
   virtual void g();
};

//test1.cpp
#include "test.h"
void str::f(){}

//test2.cpp
#include "test.h"
void str::g(){}

The vtable will be in test1.o, but not in test2.o

This is an optimisation g++ implements to avoid having to compile in-class-defined virtual methods that would get pulled in by the vtable.

The link error you describe suggests that the definition of a virtual method (str::f in the example above) is missing in your project.

JavaScript

You could create a cookie using JavaScript and check if it exists:

//Set a Cookie`
document.cookie="testcookie"`

//Check if cookie exists`
cookiesEnabled=(document.cookie.indexOf("testcookie")!=-1)? true : false`

Or you could use a jQuery Cookie plugin

//Set a Cookie`
$.cookie("testcookie", "testvalue")

//Check if cookie exists`
cookiesEnabled=( $.cookie("testcookie") ) ? true : false`

Php

setcookie("testcookie", "testvalue");

if( isset( $_COOKIE['testcookie'] ) ) {

}

Not sure if the Php will work as I'm unable to test it.

It gets serialized so that the URI can read the name value pairs in the POST request by default. You could try setting processData:false to your list of params. Not sure if that would help.

Have you tried using Linux Installer to get a full Debian build on the phone? It's billed as being able to run a full LAMP environment in about 300M and has gotten some good reviews.

Updated July 2016

As of July 2016, the Download ZIP button has moved under Clone or download to extreme-right of header under the Code tab:

If you don't see the button:

• Make sure you've selected <> Code tab from right side navigation menu, or

• Repo may not have a zip prepared. Add /archive/master.zip to the end of the repository URL and to generate a zipfile of the master branch.

  http://github.com/user/repository/

-to-

http://github.com/user/repository/archive/master.zip

to get the master branch source code in a zip file. You can do the same with tags and branch names, by replacing master in the URL above with the name of the branch or tag.

Below is the code that implements custom vertical scrollbar. The important detail here is to know when scrollbar is needed by calculating how much space is consumed by the controls that you add to the panel.

panelUserInput.SuspendLayout();
panelUserInput.Controls.Clear();
panelUserInput.AutoScroll = false;
panelUserInput.VerticalScroll.Visible = false;

// here you'd be adding controls

int x = 20, y = 20, height = 0;
for (int inx = 0; inx < numControls; inx++ )
{
    // this example uses textbox control
    TextBox txt = new TextBox();
    txt.Location = new System.Drawing.Point(x, y);
    // add whatever details you need for this control
    // before adding it to the panel
    panelUserInput.Controls.Add(txt);
    height = y + txt.Height;
    y += 25;
}
if (height > panelUserInput.Height)
{

If you'd like to simply open a fancybox when a javascript function is called. Perhaps in your code flow and not as a result of a click. Here's how you do it:

function openFancybox() {
  $.fancybox({
     'autoScale': true,
     'transitionIn': 'elastic',
     'transitionOut': 'elastic',
     'speedIn': 500,
     'speedOut': 300,
     'autoDimensions': true,
     'centerOnScroll': true,
     'href' : '#contentdiv'
  });
}

This creates the box using "contentdiv" and opens it.

Not exactly a setting but you can override the default TrustManager and HostnameVerifier to accept anything. Not a safe approach but in your situation, it can be acceptable.

There are currently three distinct events which may or may not be triggered when the client devices moves. Two of them are focused around orientation and the last on motion:

• ondeviceorientation is known to work on the desktop version of Chrome, and most Apple laptops seems to have the hardware required for this to work. It also works on Mobile Safari on the iPhone 4 with iOS 4.2. In the event handler function, you can access alpha, beta, gamma values on the event data supplied as the only argument to the function.

• onmozorientation is supported on Firefox 3.6 and newer. Again, this is known to work on most Apple laptops, but might work on Windows or Linux machines with accelerometer as well. In the event handler function, look for x, y, z fields on the event data supplied as first argument.

• ondevicemotion is known to work on iPhone 3GS + 4 and iPad (both with iOS 4.2), and provides data related to the current acceleration of the client device. The event data passed to the handler function has acceleration and accelerationIncludingGravity, which both have three fields for each axis: x, y, z

The "earthquake detecting" sample website uses a series of if statements to figure out which event to attach to (in a somewhat prioritized order) and passes the data received to a common tilt function:

if (window.DeviceOrientationEvent) {
    window.addEventListener("deviceorientation", function () {
        tilt([event.beta, event.gamma]);
    }, true);
} else if (window.DeviceMotionEvent) {
    window.addEventListener('devicemotion', function () {
        tilt([event.acceleration.x * 2, event.acceleration.y * 2]);
    }, true);
} else {
    window.addEventListener("MozOrientation", function () {
        tilt([orientation.x * 50, orientation.y * 50]);
    }, true);
}

The constant factors 2 and 50 are used to "align" the readings from the two latter events with those from the first, but these are by no means precise representations. For this simple "toy" project it works just fine, but if you need to use the data for something slightly more serious, you will have to get familiar with the units of the values provided in the different events and treat them with respect :)

Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.

Yes, this is an old post. Regardless, someone may find it useful. Here is another way to send parameters to event handlers.

//click handler
function add_event(event, paramA, paramB)
{
    //do something with your parameters
    alert(paramA ? 'paramA:' + paramA : '' + paramB ? '  paramB:' + paramB : '');
}

//bind handler to click event
$('.leadtoscore').click(add_event);
...
//once you've processed some data and know your parameters, trigger a click event.
//In this case, we will send 'myfirst' and 'mysecond' as parameters
$('.leadtoscore').trigger('click', {'myfirst', 'mysecond'});

//or use variables
var a = 'first',
    b = 'second';

$('.leadtoscore').trigger('click', {a, b});
$('.leadtoscore').trigger('click', {a});

Is there a way ( I mean how do I ) set a system property in a maven project? I want to access a property from my test [...]

You can set system properties in the Maven Surefire Plugin configuration (this makes sense since tests are forked by default). From Using System Properties:

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.5</version>
        <configuration>
          <systemPropertyVariables>
            <propertyName>propertyValue</propertyName>
            <buildDirectory>${project.build.directory}</buildDirectory>
            [...]
          </systemPropertyVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

and my webapp ( running locally )

Not sure what you mean here but I'll assume the webapp container is started by Maven. You can pass system properties on the command line using:

mvn -DargLine="-DpropertyName=propertyValue"

Update: Ok, got it now. For Jetty, you should also be able to set system properties in the Maven Jetty Plugin configuration. From Setting System Properties:

<project>
  ...
  <plugins>
    ...
      <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>maven-jetty-plugin</artifactId>
        <configuration>
         ...
         <systemProperties>
            <systemProperty>
              <name>propertyName</name>
              <value>propertyValue</value>
            </systemProperty>
            ...
         </systemProperties>
        </configuration>
      </plugin>
  </plugins>
</project>

So you want to take latitude/longitude coordinates and find out the pixel coordinates on your image of that location?

The main GMap2 class provides transformation to/from a pixel on the displayed map and a lat/long coordinate:

Gmap2.fromLatLngToContainerPixel(latlng)

For example:

var gmap2 = new GMap2(document.getElementById("map_canvas"));
var geocoder = new GClientGeocoder();

geocoder.getLatLng( "1600 Pennsylvania Avenue NW Washington, D.C. 20500",
    function( latlng ) {
        var pixel_coords = gmap2.fromLatLngToContainerPixel(latlng);

        window.alert( "The White House is at pixel coordinates (" + 
            pixel_coodrs.x + ", " + pixel_coords.y + ") on the " +
            "map image shown on this page." );
    }
);

So assuming that your map image is a screen grab of the Google Map display, then this will give you the correct pixel coordinate on that image of a lat/long coordinate.

Things are trickier if you're grabbing tile images and stitching them together yourself since the area of the complete tile set will lie outside the area of the displayed map.

In this case, you'll need to use the left and top values of the top-left image tile as an offset from the coordinates that fromLatLngToContainerPixel(latlng:GLatLng) gives you, subtracting the left coordinate from the x coordinate and top from the y coordinate. So if the top-left image is positioned at (-50, -122) (left, top), and fromLatLngToContainerPixel() tells you a lat/long is at pixel coordinate (150, 320), then on the image stitched together from tiles, the true position of the coordinate is at (150 - (-50), 320 - (-122)) which is (200, 442).

It's also possible that a similar GMap2 coordinate translation function:

GMap2.fromLatLngToDivPixel(latlng:GLatLng)

will give you the correct lat/long to pixel translation for the stitched-tiles case - I've not tested this, nor is it 100% clear from the API docs.

See here for more: http://code.google.com/apis/maps/documentation/reference.html#GMap2.Methods.Coordinate-Transformations

This is the only thing that worked for me for both IE and Google Chrome, I think it's mostly because of the .body.scrollHeight stuff, which works in IE best. I put +30 for Firefox ...

jQuery.fancybox({
  href: href,
  type: "iframe",
  centerOnScroll: 'true',
  scrolling: 'no',
  width: 650,
  'onComplete': function() {
    jQuery('#fancybox-frame').load(function() {
      jQuery('#fancybox-content').height(this.contentWindow.document.body.scrollHeight + 30);
    });
  }
});

Starting with MVC 5, you can also use Attribute Routing to move the URL parameter configuration to your controllers.

A detailed discussion is available here: http://blogs.msdn.com/b/webdev/archive/2013/10/17/attribute-routing-in-asp-net-mvc-5.aspx

Summary:

First you enable attribute routing

 public class RouteConfig 
 {
     public static void RegisterRoutes(RouteCollection routes)
     {
         routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

         routes.MapMvcAttributeRoutes();
     } 
 }

Then you can use attributes to define parameters and optionally data types

public class BooksController : Controller
{
    // eg: /books
    // eg: /books/1430210079
    [Route("books/{isbn?}")]
    public ActionResult View(string isbn)

This following works better if you need to scroll to an arbitrary item in the list (rather than always to the bottom):

function scrollIntoView(element, container) {
  var containerTop = $(container).scrollTop(); 
  var containerBottom = containerTop + $(container).height(); 
  var elemTop = element.offsetTop;
  var elemBottom = elemTop + $(element).height(); 
  if (elemTop < containerTop) {
    $(container).scrollTop(elemTop);
  } else if (elemBottom > containerBottom) {
    $(container).scrollTop(elemBottom - $(container).height());
  }
}

Using listAbbreviations() makes no sense as for every area it returns all the different offsets that were historically used there, not just current ones. The right base source of the list is definitely listIdentifiers().

I would generate the list just once and save it to avoid generating it for every request. I could refresh it once a month.

Also, I could put all the timezones info into a separate js-script and generate the select list itself on the client side. The js-script could be cached as well, timezones don't change often.

Also, using javascript on the client side, you can know the current local time, and hence you can find the zones that have the same time now (minutes may differ, so comparison should be approximate), and display them on the top of the list, so the user does not have to scroll through all the 400 items. You can also display adjacent zones (+/-1 hour) following.

Linalg code that relies heavily on Pentiums and later processors' vector computing capabilities (starting with the MMX extensions, like LAPACK and now Atlas BLAS) is not "fantastically optimized", but simply industry-standard. To replicate that perfomance in Java you are going to need native libraries. I have had the same performance problem as you describe (mainly, to be able to compute Choleski decompositions) and have found nothing really efficient: Jama is pure Java, since it is supposed to be just a template and reference kit for implementers to follow... which never happened. You know Apache math commons... As for COLT, I have still to test it but it seems to rely heavily on Ninja improvements, most of which were reached by building an ad-hoc Java compiler, so I doubt it's going to help. At that point, I think we "just" need a collective effort to build a native Jama implementation...

You have a compareTo function already ... I would implement the Comparable interface.

May not really matter for whatever you're going to do with it though.

The original code (I added the line numbers so can refer to them):

1  var text = ' name = oscar '
2  var dict = new Array();
3  var keyValuePair = text.split(' = ');
4  dict[ keyValuePair[0] ] = 'whatever';
5  alert( dict ); // Prints nothing.

Almost there...

• line 1: you should do a trim on text so it is name = oscar.

• line 3: okay as long as you always have spaces around your equal. It might be better to not trim in line 1. Use = and trim each keyValuePair

• add a line after 3 and before 4:

    key = keyValuePair[0];`
  

• line 4: Now becomes:

    dict[key] = keyValuePair[1];
  

• line 5: Change to:

    alert( dict['name'] );  // It will print out 'oscar'
  

I'm trying to say that the dict[keyValuePair[0]] does not work. You need to set a string to keyValuePair[0] and use that as the associative key. That is the only way I got mine to work. After you have set it up, you can either refer to it with numeric index or key in quotes.

Best way to achieve is to use a LinkedHashMap that maintains insertion order of elements. Following is an sample code:

public class Solution {

Map<Integer,Integer> cache;
int capacity;
public Solution(int capacity) {
    this.cache = new LinkedHashMap<Integer,Integer>(capacity); 
    this.capacity = capacity;

}

// This function returns false if key is not 
// present in cache. Else it moves the key to 
// front by first removing it and then adding 
// it, and returns true. 

public int get(int key) {
if (!cache.containsKey(key)) 
        return -1; 
    int value = cache.get(key);
    cache.remove(key); 
    cache.put(key,value); 
    return cache.get(key); 

}

public void set(int key, int value) {

    // If already present, then  
    // remove it first we are going to add later 
       if(cache.containsKey(key)){
        cache.remove(key);
    }
     // If cache size is full, remove the least 
    // recently used. 
    else if (cache.size() == capacity) { 
        Iterator<Integer> iterator = cache.keySet().iterator();
        cache.remove(iterator.next()); 
    }
        cache.put(key,value);
}

}

I had the same problem and solved it using a boolean flag that gets set when the form is closing (the System.Timers.Timer does not have an IsDisposed property). Everywhere on the form I was starting the timer, I had it check this flag. If it was set, then don't start the timer. Here's the reason:

The Reason:

I was stopping and disposing of the timer in the form closing event. I was starting the timer in the Timer_Elapsed() event. If I were to close the form in the middle of the Timer_Elapsed() event, the timer would immediately get disposed by the Form_Closing() event. This would happen before the Timer_Elapsed() event would finish and more importantly, before it got to this line of code:

_timer.Start()

As soon as that line was executed an ObjectDisposedException() would get thrown with the error you mentioned.

The Solution:

Private Sub myForm_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
    ' set the form closing flag so the timer doesn't fire even after the form is closed.
    _formIsClosing = True
    _timer.Stop()
    _timer.Dispose()
End Sub

Here's the timer elapsed event:

Private Sub Timer_Elapsed(ByVal sender As System.Object, ByVal e As System.Timers.ElapsedEventArgs) Handles _timer.Elapsed
    ' Don't want the timer stepping on itself (ie. the time interval elapses before the first call is done processing)
    _timer.Stop()

    ' do work here

    ' Only start the timer if the form is open. Without this check, the timer will run even if the form is closed.
    If Not _formIsClosing Then
        _timer.Interval = _refreshInterval
        _timer.Start() ' ObjectDisposedException() is thrown here unless you check the _formIsClosing flag.
    End If
End Sub

The interesting thing to know, even though it would throw the ObjectDisposedException when attempting to start the timer, the timer would still get started causing it to run even when the form was closed (the thread would only stop when the application was closed).

I've had to work with several beginner (never wrote a line of code) programmers, and I'll be doing an after school workshop with high school students this fall. This is the closest thing I've got to documentation. It's still a work in progress, but I hope it helps.

1) FizzBuzz. Start with command line programs. You can write some fun games, or tools, very quickly, and you learn all of the language features very quickly without having to learn the GUI tools first. These early apps should be simple enough that you won't need to use any real debugging tools to make them work.

If nothing else things like FizzBuzz are good projects. Your first few apps should not have to deal with DBs, file system, configuration, ect. These are concepts which just confuse most people, and when you're just learning the syntax and basic framework features you really don't need more complexity.

Some projects:

• Hello World!
• Take the year of my birth, and calculate my age (just (now - then) no month corrections). (simple math, input, output)
• Ask for a direction(Up, down, left, right), then tell the user their fate (fall in a hole, find a cake, ect). (Boolean logic)
• FizzBuzz, but count once every second. (Loops, timers, and more logic)
• Depending on their age some really like an app which calls the users a random insult at some interval. (Loops, arrays, timers, and random if you make the interval random)

2) Simple Project Once they have a good grasp of language features, you can start a project(simple, fun games work good.). You should try to have the first project be able to be completed within 6-12 hours. Don't spend time to architect it early. Let them design it even if it sucks. If it falls apart, talk about what happened and why it failed, then pick another topic and start again.

This is where you start introducing the debugging capabilities of your tools. Even if you can see the problem by reading the code you should teach them how to use the tools, and then show them how you could see it. That serves the dual purpose of teaching the debugging tools and teaching how to ID errors without tools.

Once, or if, the project gets functional you can use it to introduce refactoring tools. Its good if you can then expand the project with some simple features which you never planned for. This usually means refactoring and significant debugging, since very few people write even half decent code their first time.

Some projects:

• Hangman game
• Experimenting with robotics(Vex and Mindstorms are options)

3) Real Project Start a real project which may take some time. Use proper source control, and make a point to have a schedule. Run this project like a real project, if nothing else its good experience having to deal with the tools.

Obviously you need to adjust this for each person. The most important thing I've found is to make even the first simple apps apply to what the person is interested in.

Some projects:

• Tetris
• Text file based blog engine
• More advanced robotics work

First, the signature of your data() function:

bool data(struct *sampleData)

cannot possibly work, because the argument lacks a name. When you declare a function argument that you intend to actually access, it needs a name. So change it to something like:

bool data(struct sampleData *samples)

But in C++, you don't need to use struct at all actually. So this can simply become:

bool data(sampleData *samples)

Second, the sampleData struct is not known to data() at that point. So you should declare it before that:

struct sampleData {
    int N;
    int M;
    string sample_name;
    string speaker;
};

bool data(sampleData *samples)
{
    samples->N = 10;
    samples->M = 20;
    // etc.
}

And finally, you need to create a variable of type sampleData. For example, in your main() function:

int main(int argc, char *argv[]) {
    sampleData samples;
    data(&samples);
}

Note that you need to pass the address of the variable to the data() function, since it accepts a pointer.

However, note that in C++ you can directly pass arguments by reference and don't need to "emulate" it with pointers. You can do this instead:

// Note that the argument is taken by reference (the "&" in front
// of the argument name.)
bool data(sampleData &samples)
{
    samples.N = 10;
    samples.M = 20;
    // etc.
}

int main(int argc, char *argv[]) {
    sampleData samples;

    // No need to pass a pointer here, since data() takes the
    // passed argument by reference.
    data(samples);
}

char ch = 't';
char chArray[2];
sprintf(chArray, "%c", ch);
char chOutput[10]="tes";
strcat(chOutput, chArray);
cout<<chOutput;

OUTPUT:

test

Use DateTime::diff (aka date_diff):

$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);

Or:

$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);

You can then get the interval as a integer by calling $interval->days.

If you look at Twitter's own container-app.html demo on GitHub, you'll get some ideas on using borders with their grid.

For example, here's the extracted part of the building blocks to their 940-pixel wide 16-column grid system:

.row {
    zoom: 1;
    margin-left: -20px;
}

.row > [class*="span"] {
    display: inline;
    float: left;
    margin-left: 20px;
}

.span4 {
    width: 220px;
}

To allow for borders on specific elements, they added embedded CSS to the page that reduces matching classes by enough amount to account for the border(s).

For example, to allow for the left border on the sidebar, they added this CSS in the <head> after the the main <link href="../bootstrap.css" rel="stylesheet">.

.content .span4 {
    margin-left: 0;
    padding-left: 19px;
    border-left: 1px solid #eee;
}

You'll see they've reduced padding-left by 1px to allow for the addition of the new left border. Since this rule appears later in the source order, it overrides any previous or external declarations.

I'd argue this isn't exactly the most robust or elegant approach, but it illustrates the most basic example.

For our app we had to use both these parameters access_type=offline&prompt=consent. approval_prompt=force did not work for us

What if you hooked the window resize event:

$(window).resize(function() 
{    
    chart.setSize(
       $(document).width(), 
       $(document).height()/2,
       false
    );   
});

See example fiddle here.

Highcharts API Reference : setSize().

I am adding my comment for completeness, as the solutions listed here did not help me. On PHP 5.6, SoapClient makes the first call to the specified WSDL URL in SoapClient::SoapClient and after connecting to it and receiving the result, it tries to connect to the WSDL specified in the result in:

<soap:address location="http://"/>

And the call fails with error Could not connect to host if the WSDL is different than the one you specified in SoapClient::SoapClient and is unreachable (my case was SoapUI using http://host.local/).

The behaviour in PHP 5.4 is different and it always uses the WSDL in SoapClient::SoapClient.

Have you checked in console if data from form is properly serialized? Is ajax request successful? Also you didn't close placeholder quote in, which can cause some problems:

 <textarea name="comentarii" cols="36" rows="5" placeholder="Message>  

You can use monitorEvents function.

Just inspect your element (right mouse click ? Inspect on visible element or go to Elements tab in Chrome Developer Tools and select wanted element) then go to Console tab and write:

monitorEvents($0)

Now when you move mouse over this element, focus or click it, the name of the fired event will be displayed with its data.

To stop getting this data just write this to console:

unmonitorEvents($0)

$0 is just the last DOM element selected by Chrome Developer Tools. You can pass any other DOM object there (for example result of getElementById or querySelector).

You can also specify event "type" as second parameter to narrow monitored events to some predefined set. For example:

monitorEvents(document.body, 'mouse')

List of this available types is here.

I made a small gif that illustrates how this feature works:

I'm learning AngularJS and was struggling with selection as well. I know this question is already answered, but I wanted to share some more code nevertheless.

In my test I have two listboxes: car makes and car models. The models list is disabled until some make is selected. If selection in makes listbox is later reset (set to 'Select Make') then the models listbox becomes disabled again AND its selection is reset as well (to 'Select Model'). Makes are retrieved as a resource while models are just hard-coded.

Makes JSON:

[
{"code": "0", "name": "Select Make"},
{"code": "1", "name": "Acura"},
{"code": "2", "name": "Audi"}
]

services.js:

angular.module('makeServices', ['ngResource']).
factory('Make', function($resource){
    return $resource('makes.json', {}, {
        query: {method:'GET', isArray:true}
    });
});

HTML file:

<div ng:controller="MakeModelCtrl">
  <div>Make</div>
  <select id="makeListBox"
      ng-model="make.selected"
      ng-options="make.code as make.name for make in makes"
      ng-change="makeChanged(make.selected)">
  </select>

  <div>Model</div>
  <select id="modelListBox"
     ng-disabled="makeNotSelected"
     ng-model="model.selected"
     ng-options="model.code as model.name for model in models">
  </select>
</div>

controllers.js:

function MakeModelCtrl($scope)
{
    $scope.makeNotSelected = true;
    $scope.make = {selected: "0"};
    $scope.makes = Make.query({}, function (makes) {
         $scope.make = {selected: makes[0].code};
    });

    $scope.makeChanged = function(selectedMakeCode) {
        $scope.makeNotSelected = !selectedMakeCode;
        if ($scope.makeNotSelected)
        {
            $scope.model = {selected: "0"};
        }
    };

    $scope.models = [
      {code:"0", name:"Select Model"},
      {code:"1", name:"Model1"},
      {code:"2", name:"Model2"}
    ];
    $scope.model = {selected: "0"};
}

Arguably, it is an example of syntactic sugar, since it is implemented as an array anyways (which doesn't mean it's useless) - I prefer passing an array to keep it clear, and also declare methods with arrays of given type. Rather an opinion than an answer, though.

Metrics and Svens answer deals with the usual situation but for us who work in non-english enviroments if you have exotic characters (å,ä,ö) in your character variable you will get the same result, even if you have multiple factor levels.

Levels <- c("Pri", "För") gives the contrast error, while Levels <- c("Pri", "For") doesn't

This is probably a bug.

You shouldn't be using an item defined in the Layout XML in order to create more instances of it. You should either create it in a separate XML and inflate it or create the TableRow programmaticaly. If creating them programmaticaly, should be something like this:

    public void init(){
    TableLayout ll = (TableLayout) findViewById(R.id.displayLinear);


    for (int i = 0; i <2; i++) {

        TableRow row= new TableRow(this);
        TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
        row.setLayoutParams(lp);
        checkBox = new CheckBox(this);
        tv = new TextView(this);
        addBtn = new ImageButton(this);
        addBtn.setImageResource(R.drawable.add);
        minusBtn = new ImageButton(this);
        minusBtn.setImageResource(R.drawable.minus);
        qty = new TextView(this);
        checkBox.setText("hello");
        qty.setText("10");
        row.addView(checkBox);
        row.addView(minusBtn);
        row.addView(qty);
        row.addView(addBtn);
        ll.addView(row,i);
    }
}

According to this, you need to assign a height to the element in which the div is contained in order for 100% height to work. Does that work for you?

I was facing the same problem while importing the project-related(non standard) modules. Detailed explanation of the problem

Directory structure:

Project_dir:
    .vscode/settings.json
    dir_1
        > a
        > b
        > c
    dir_2
        > x
        > y
        > z

What we want:

Project_dir
    dir_3
        import a
        import y

Here "import a" and "import y" fails with following error:

Import "dir_1.a" could not be resolvedPylancereportMissingImports
Import "dir_2.y" could not be resolvedPylancereportMissingImports

What worked for me:

Appending the top directory which contains the modules to be imported.

In above example add the follwoing "Code to append" in ".vscode/settings.json"

Filename:

.vscode/settings.json

Code to append:

"python.analysis.extraPaths": [dir_1, dir_2]

What other answers missed, is that the path given to the function could actually be a directory. Following function makes sure, that the path is really a file.

func fileExists(filename string) bool {
    info, err := os.Stat(filename)
    if os.IsNotExist(err) {
        return false
    }
    return !info.IsDir()
}

Another thing to point out: This code could still lead to a race condition, where another thread or process deletes or creates the specified file, while the fileExists function is running.

If you're worried about this, use a lock in your threads, serialize the access to this function or use an inter-process semaphore if multiple applications are involved. If other applications are involved, outside of your control, you're out of luck, I guess.

You can do it the OO way, just an alternative and flexible:

class Logger {

    private
        $file,
        $timestamp;

    public function __construct($filename) {
        $this->file = $filename;
    }

    public function setTimestamp($format) {
        $this->timestamp = date($format)." » ";
    }

    public function putLog($insert) {
        if (isset($this->timestamp)) {
            file_put_contents($this->file, $this->timestamp.$insert."<br>", FILE_APPEND);
        } else {
            trigger_error("Timestamp not set", E_USER_ERROR);
        }
    }

    public function getLog() {
        $content = @file_get_contents($this->file);
        return $content;
    }

}

Then use it like this .. let's say you have user_name stored in a session (semi pseudo code):

$log = new Logger("log.txt");
$log->setTimestamp("D M d 'y h.i A");

if (user logs in) {
    $log->putLog("Successful Login: ".$_SESSION["user_name"]);
}
if (user logs out) {
    $log->putLog("Logout: ".$_SESSION["user_name"]);
}

Check your log with this:

$log->getLog();

Result is like:

Sun Jul 02 '17 05.45 PM » Successful Login: JohnDoe
Sun Jul 02 '17 05.46 PM » Logout: JohnDoe

pgAdmin has GUI for data import since 1.16. You have to create your table first and then you can import data easily - just right-click on the table name and click on Import.

Getting the Text of ComboBox when the item is changed

     self.ui.comboBox.activated.connect(self.pass_Net_Adap)

  def pass_Net_Adap(self):
      print str(self.ui.comboBox.currentText())

Best way to do this is setting the below property:

set hive.cli.print.header=true;
set hive.resultset.use.unique.column.names=false;

"SELECT Applicant.applicantId, Applicant.lastName, Applicant.firstName, Applicant.middleName, Applicant.status,Applicant.companyId, Company.name, Applicant.createDate FROM (Applicant INNER JOIN Company ON Applicant.companyId = Company.companyId) WHERE Applicant.createDate between  '" +dateTimePicker1.Text.ToString() + "'and '"+dateTimePicker2.Text.ToString() +"'";

How can I validate if a String is null or empty using the c tags of JSTL?

You can use the empty keyword in a <c:if> for this:

<c:if test="${empty var1}">
    var1 is empty or null.
</c:if>
<c:if test="${not empty var1}">
    var1 is NOT empty or null.
</c:if>

Or the <c:choose>:

<c:choose>
    <c:when test="${empty var1}">
        var1 is empty or null.
    </c:when>
    <c:otherwise>
        var1 is NOT empty or null.
    </c:otherwise>
</c:choose>

Or if you don't need to conditionally render a bunch of tags and thus you could only check it inside a tag attribute, then you can use the EL conditional operator ${condition? valueIfTrue : valueIfFalse}:

<c:out value="${empty var1 ? 'var1 is empty or null' : 'var1 is NOT empty or null'}" />

To learn more about those ${} things (the Expression Language, which is a separate subject from JSTL), check here.

You can do as mservidio suggested, or even better, keep track of your culture using this overload:

DateTime.Now.ToString("MMMM", CultureInfo.InvariantCulture);

Ahhh, the stupid linesize ... Here is what I do in my profile.sql - works only on unixes:

echo SET LINES $(tput cols) > $HOME/.login_tmp.sql
@$HOME/.login_tmp.sql

if you find an equivalent for tput on Windows, it might work there as well

The C++ String Toolkit Library (Strtk) has the following solution to your problem:

#include <string>
#include <deque>
#include <vector>
#include "strtk.hpp"
int main()
{ 
   std::string int_string = "1,2,3,4,5,6,7,8,9,10,11,12,13,14,15";
   std::vector<int> int_list;
   strtk::parse(int_string,",",int_list);

   std::string double_string = "123.456|789.012|345.678|901.234|567.890";
   std::deque<double> double_list;
   strtk::parse(double_string,"|",double_list);

   return 0;
}

I mostly prefer Criteria Queries for dynamic queries. For example it is much easier to add some ordering dynamically or leave some parts (e.g. restrictions) out depending on some parameter.

On the other hand I'm using HQL for static and complex queries, because it's much easier to understand/read HQL. Also, HQL is a bit more powerful, I think, e.g. for different join types.

function submitForm()
{
    if (testSubmit())
    {
        document.forms["myForm"].submit(); //first submit
        document.forms["myForm"].reset(); //and then reset the form values
    }
} </script> <body>
<form method="get" name="myForm">

    First Name: <input type="text" name="input1"/>
    <br/>
    Last Name: <input type="text" name="input2"/>
    <br/>
    <input type="button" value="Submit" onclick="submitForm()"/>
</form>

Use this following very simple JAVA 8 Runnable Class feature

public class MultiThreadExample {

static AtomicInteger atomicNumber = new AtomicInteger(1);

public static void main(String[] args) {
    Runnable print = () -> {
        while (atomicNumber.get() < 10) {
            synchronized (atomicNumber) {
                if ((atomicNumber.get() % 2 == 0) && "Even".equals(Thread.currentThread().getName())) {
                    System.out.println("Even" + ":" + atomicNumber.getAndIncrement());
                } else if ((atomicNumber.get() % 2 != 0) && "Odd".equals(Thread.currentThread().getName())) {
                    System.out.println("Odd" + ":" + atomicNumber.getAndIncrement());
                }
            }
        }
    };

    Thread t1 = new Thread(print);
    t1.setName("Even");
    t1.start();
    Thread t2 = new Thread(print);
    t2.setName("Odd");
    t2.start();

}
}

Permission denied

In order to run a script the file must have an executable permission bit set.

In order to fully understand Linux file permissions you can study the documentation for the chmod command. chmod, an abbreviation of change mode, is the command that is used to change the permission settings of a file.

To read the chmod documentation for your local system , run man chmod or info chmod from the command line. Once read and understood you should be able to understand the output of running ...

ls -l foo.sh

... which will list the READ, WRITE and EXECUTE permissions for the file owner, the group owner and everyone else who is not the file owner or a member of the group to which the file belongs (that last permission group is sometimes referred to as "world" or "other")

Here's a summary of how to troubleshoot the Permission Denied error in your case.

$ ls -l foo.sh                    # Check file permissions of foo
-rw-r--r-- 1 rkielty users 0 2012-10-21 14:47 foo.sh 
    ^^^ 
 ^^^ | ^^^   ^^^^^^^ ^^^^^
  |  |  |       |       | 
Owner| World    |       |
     |          |    Name of
   Group        |     Group
             Name of 
              Owner 

Owner has read and write access rw but the - indicates that the executable permission is missing

The chmod command fixes that. (Group and other only have read permission set on the file, they cannot write to it or execute it)

$ chmod +x foo.sh               # The owner can set the executable permission on foo.sh
$ ls -l foo.sh                  # Now we see an x after the rw 
-rwxr-xr-x 1 rkielty users 0 2012-10-21 14:47 foo.sh
   ^  ^  ^

foo.sh is now executable as far as Linux is concerned.

Using sudo results in Command not found

When you run a command using sudo you are effectively running it as the superuser or root.

The reason that the root user is not finding your command is likely that the PATH environment variable for root does not include the directory where foo.sh is located. Hence the command is not found.

The PATH environment variable contains a list of directories which are searched for commands. Each user sets their own PATH variable according to their needs. To see what it is set to run

env | grep ^PATH

Here's some sample output of running the above env command first as an ordinary user and then as the root user using sudo

rkielty@rkielty-laptop:~$ env | grep ^PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

rkielty@rkielty-laptop:~$ sudo env | grep ^PATH
[sudo] password for rkielty: 
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

Note that, although similar, in this case the directories contained in the PATH the non-privileged user (rkielty) and the super user are not the same.

The directory where foo.sh resides is not present in the PATH variable of the root user, hence the command not found error.

To use a ternary operator without else inside of an array or object declaration, you can use the ES6 spread operator, ...():

const cond = false;
const arr = [
  ...(cond ? ['a'] : []),
  'b',
];
    // ['b']

And for objects:

const cond = false;
const obj = {
  ...(cond ? {a: 1} : {}),
  b: 2,
};
    // {b: 2}

Use toString() when you want to present information to a user (including a developer looking at a log). Never rely in your code on toString() giving a specific value. Never test it against a specific string. If your code breaks when someone correctly changes the toString() return, then it was already broken.

If you need to get the exact name used to declare the enum constant, you should use name() as toString may have been overridden.

I assume you're using some version of Visual Studio? In windows, std::cout << "something"; should write something to a console window IF your program is setup in the project settings as a console program.

There is no notion of method overloading in Python. But you can achieve a similar effect by specifying optional and keyword arguments

I got it working like this:

TestClass.Java

package classes;

public class TestClass {

    public static void main(String[] args) {
        System.out.println("Test");
    }

}

Use javac on the command line to produce TestClass.class. Put TestClass.class in a folder classes/.

MANIFEST.MF

Manifest-Version: 1.0
Main-Class: classes.TestClass

Then run

jar cfm test.jar MANIFEST.MF classes/

Then run it as

java -jar test.jar

In JUnit 4, another option for you may be to create an annotation to denote that the test needs to meet your custom criteria, then extend the default runner with your own and using reflection, base your decision on the custom criteria. It may look something like this:

public class CustomRunner extends BlockJUnit4ClassRunner {
    public CTRunner(Class<?> klass) throws initializationError {
        super(klass);
    }

    @Override
    protected boolean isIgnored(FrameworkMethod child) {
        if(shouldIgnore()) {
            return true;
        }
        return super.isIgnored(child);
    }

    private boolean shouldIgnore(class) {
        /* some custom criteria */
    }
}

<input type="button" value="Click me" id="myButton" />

<script type="text/javascript">
    var myButton = document.getElementById("myButton");

    myButton.myMessage = "it's working";

    myButton.onclick = function() { alert(this.myMessage); };


</script>

This works in my test suite which includes everything from IE6+. The anonymous function is aware of the object which it belongs to therefore you can pass data with the object that's calling it ( in this case myButton ).

When installing npm packages (both globally or locally) you can define a specific version by using the @version syntax to define a version to be installed.

In other words, doing: npm install -g [email protected] will ensure that only 0.9.2 is installed and won't reinstall if it already exists.

As a word of a advice, I would suggest avoiding global npm installs wherever you can. Many people don't realize that if a dependency defines a bin file, it gets installed to ./node_modules/.bin/. Often, its very easy to use that local version of an installed module that is defined in your package.json. In fact, npm scripts will add the ./node_modules/.bin onto your path.

As an example, here is a package.json that, when I run npm install && npm test will install the version of karma defined in my package.json, and use that version of karma (installed at node_modules/.bin/karma) when running the test script:

{
 "name": "myApp",
 "main": "app.js",
 "scripts": {
   "test": "karma test/*",
 },
 "dependencies": {...},
 "devDependencies": {
   "karma": "0.9.2"
 }
}

This gives you the benefit of your package.json defining the version of karma to use and not having to keep that config globally on your CI box.

}

Hope this helps. Good luck!

If you've changed the search_path, specify the public schema in the function call:

public.uuid_generate_v4()

Yes, you are using it incorrectly, Series.replace() is not inplace operation by default, it returns the replaced dataframe/series, you need to assign it back to your dataFrame/Series for its effect to occur. Or if you need to do it inplace, you need to specify the inplace keyword argument as True Example -

data['sex'].replace(0, 'Female',inplace=True)
data['sex'].replace(1, 'Male',inplace=True)

Also, you can combine the above into a single replace function call by using list for both to_replace argument as well as value argument , Example -

data['sex'].replace([0,1],['Female','Male'],inplace=True)

Example/Demo -

In [10]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])

In [11]: data['sex'].replace([0,1],['Female','Male'],inplace=True)

In [12]: data
Out[12]:
      sex  split
0    Male      0
1  Female      1
2    Male      0
3  Female      1

You can also use a dictionary, Example -

In [15]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])

In [16]: data['sex'].replace({0:'Female',1:'Male'},inplace=True)

In [17]: data
Out[17]:
      sex  split
0    Male      0
1  Female      1
2    Male      0
3  Female      1

insert the result of the SP into a temp table, then join:

CREATE TABLE #Temp (
    TenantID int, 
    TenantBalance int
)

INSERT INTO #Temp

SELECT t.TenantName, t.CarPlateNumber, t.CarColor, t.Sex, t.SSNO, t.Phone, t.Memo,
    u.UnitNumber, p.PropertyName
FROM tblTenant t
INNER JOIN #Temp ON t.TenantID = #Temp.TenantID
...

there are multiple ways to do this without using any third-party code or libraries (the recommended way).

1st STATIC WAY: create a .json file then import it in your react component example

my file name is "example.json"

{"example" : "my text"}

the example key inside the example.json can be anything just keep in mind to use double quotes to prevent future issues.

How to import in react component

import myJson from "jsonlocation";

and you can use it anywhere like this

myJson.example

now there are a few things to consider. With this method, you are forced to declare your import at the top of the page and cannot dynamically import anything.

Now, what about if we want to dynamically import the JSON data? example a multi-language support website?

2 DYNAMIC WAY

1st declare your JSON file exactly like my example above

but this time we are importing the data differently.

let language = require('./en.json');

this can access the same way.

but wait where is the dynamic load?

here is how to load the JSON dynamically

let language = require(`./${variable}.json`);

now make sure all your JSON files are within the same directory

here you can use the JSON the same way as the first example

myJson.example

what changed? the way we import because it is the only thing we really need.

I hope this helps.

It seems, that the simple way

-Dmaven.javadoc.skip=true

does not work with the release-plugin. in this case you have to pass the parameter as an "argument"

mvn release:perform -Darguments="-Dmaven.javadoc.skip=true"

The shortest way to do that would be:

do {
    // Something
} while (*url);

Basically, *url will return the char at the first position in the array; since C strings are null-terminated, if the string is empty, its first position will be the character '\0', whose ASCII value is 0; since C logical statements treat every zero value as false, this loop will keep going while the first position of the string is non-null, that is, while the string is not empty.

Recommended readings if you want to understand this better:

• C strings: https://www.tutorialspoint.com/cprogramming/c_strings.htm
• C arrays: https://www.tutorialspoint.com/cprogramming/c_arrays.htm
• Relation between arrays and pointers: https://www.programiz.com/c-programming/c-pointers-arrays
• Logical operators: https://www.tutorialspoint.com/cprogramming/c_logical_operators.htm

In my case I need to do

sudo npm install  

my project is inside /var/www so I also need to set proper permissions.

The most obvious, language independent, answer is to use a series of 'if'.

If the language you are using has function pointers (C) or has functions that are 1st class values (Lua) you may achieve results similar to a "switch" using an array (or a list) of (pointers to) functions.

You should be more specific on the language if you want better answers.

I agree with Matti. Would be easy to do with some simple javascript. A quick jquery example would be something like this:

<tr>
  <td><a href="http://www.example.com/">example</a></td>
  <td>another cell</td>
  <td>one more</td>
</tr>

and

$('tr').click( function() {
    window.location = $(this).find('a').attr('href');
}).hover( function() {
    $(this).toggleClass('hover');
});

then in your CSS

tr.hover {
   cursor: pointer;
   /* whatever other hover styles you want */
}

This is my solution to fibonacci problem with recursion.

#include <iostream>
using namespace std;

int fibonacci(int n){
    if(n<=0)
        return 0;
    else if(n==1 || n==2)
        return 1;
    else
        return (fibonacci(n-1)+fibonacci(n-2));
}

int main() {
    cout << fibonacci(8);
    return 0;
}

What do you mean by nothing?

<a href='about:blank'>blank page</a>

or

<a href='whatever' onclick='return false;'>won't navigate</a>

This worked for me on Mac

sudo chown -R $(whoami) $(brew --prefix)/*

Search in your code maybe you have initialized dataTable twice in your code. You shold have like this code:

$('#example').dataTable( {paging: false} );

Only one time in your code.

Ruby Array objects have a great method, select.

select {|item| block } ? new_ary
select ? an_enumerator

The first form is what interests you here. It allows you to select objects which pass a test.

Ruby Array objects have another method, count.

count ? int
count(obj) ? int
count { |item| block } ? int

In this case, you are interested in duplicates (objects which appear more than once in the array). The appropriate test is a.count(obj) > 1.

If a = ["A", "B", "C", "B", "A"], then

a.select{|item| a.count(item) > 1}.uniq
=> ["A", "B"]

You state that you only want one object. So pick one.

An object is only once in memory. Your first addition to list just adds the object references.

anotherList.addAll will also just add the references. So still only 100 objects in memory.

If you change list by adding/removing elements, anotherList won't be changed. But if you change any object in list, then it's content will be also changed, when accessing it from anotherList, because the same reference is being pointed to from both lists.

If you just want to install PHP no matter what version it is, try PHP7

    $.fn.css = function() {

        $(this).trigger(ev);
    }
})();

$('#element').bind('display', function(e) {
    alert("display has changed to :" + $(this).attr('style') );
});

$('#element').css("display", "none")// i change the style in this line !!
$('#element').css("display", "block")// i change the style in this line !!

You should set body and html to position:fixed;, and then set right:, left:, top:, and bottom: to 0;. That way, even if content overflows it will not extend past the limits of the viewport.

For example:

<html>
<body>
    <div id="wrapper"></div>
</body>
</html>

CSS:

html, body, {
    position:fixed;
    top:0;
    bottom:0;
    left:0;
    right:0;
}

JS Fiddle Example

Caveat: Using this method, if the user makes their window smaller, content will be cut off.

First one needs to create cookie (I have wrapped token inside cookie as an example) and then set it in response.To use the cookie in following way install cookieParser

app.use(cookieParser());

The browser will have it saved in its 'Resource' tab and will be used for every request thereafter taking the initial URL as base

var token = student.generateToken('authentication');
        res.cookie('token', token, {
            expires: new Date(Date.now() + 9999999),
            httpOnly: false
        }).status(200).send();

To get cookie from a request on the server side is easy too.You have to extract the cookie from request by calling 'cookie' property of the request object.

var token = req.cookies.token; // Retrieving Token stored in cookies

On my JDK (Windows 10 64 bit, 1.8.0_65-b17) I can reproduce and explain:

public static void main(String[] args) {
    int repeat = 10;
    long A = 0;
    long B = 0;
    for (int i = 0; i < repeat; i++) {
        A += test();
        B += testB();
    }

    System.out.println(A / repeat + " ms");
    System.out.println(B / repeat + " ms");
}


private static long test() {
    int n = 0;
    for (int i = 0; i < 1000; i++) {
        n += multi(i);
    }
    long startTime = System.currentTimeMillis();
    for (int i = 0; i < 1000000000; i++) {
        n += multi(i);
    }
    long ms = (System.currentTimeMillis() - startTime);
    System.out.println(ms + " ms A " + n);
    return ms;
}


private static long testB() {
    int n = 0;
    for (int i = 0; i < 1000; i++) {
        n += multiB(i);
    }
    long startTime = System.currentTimeMillis();
    for (int i = 0; i < 1000000000; i++) {
        n += multiB(i);
    }
    long ms = (System.currentTimeMillis() - startTime);
    System.out.println(ms + " ms B " + n);
    return ms;
}

private static int multiB(int i) {
    return 2 * (i * i);
}

private static int multi(int i) {
    return 2 * i * i;
}

Output:

...
405 ms A 785527736
327 ms B 785527736
404 ms A 785527736
329 ms B 785527736
404 ms A 785527736
328 ms B 785527736
404 ms A 785527736
328 ms B 785527736
410 ms
333 ms

So why? The byte code is this:

 private static multiB(int arg0) { // 2 * (i * i)
     <localVar:index=0, name=i , desc=I, sig=null, start=L1, end=L2>

     L1 {
         iconst_2
         iload0
         iload0
         imul
         imul
         ireturn
     }
     L2 {
     }
 }

 private static multi(int arg0) { // 2 * i * i
     <localVar:index=0, name=i , desc=I, sig=null, start=L1, end=L2>

     L1 {
         iconst_2
         iload0
         imul
         iload0
         imul
         ireturn
     }
     L2 {
     }
 }

The difference being: With brackets (2 * (i * i)):

• push const stack
• push local on stack
• push local on stack
• multiply top of stack
• multiply top of stack

Without brackets (2 * i * i):

• push const stack
• push local on stack
• multiply top of stack
• push local on stack
• multiply top of stack

Loading all on the stack and then working back down is faster than switching between putting on the stack and operating on it.

The above problem can also be solved using ConstraintLayout through Guidelines.

Below is the snippet.

<?xml version="1.0" encoding="utf-8"?>

See Bit Twiddling Hacks for a much shorter version of the answer you accepted. It also has the benefit of finding the answer sooner if your input is normally distributed, by checking the big constants first. (v >= 1000000000) catches 76% of the values, so checking that first will on average be faster.

When using JetBrains IDE's with Git, "stashing and unstashing actions are supported in addition to shelving and unshelving. These features have much in common; the major difference is in the way patches are generated and applied. Shelve can operate with either individual files or bunch of files, while Stash can only operate with a whole bunch of changed files at once. Here are some more details on the differences between them."

use android:layout_gravity instead of android:gravity

android:gravity sets the gravity of the content of the View its used on. android:layout_gravity sets the gravity of the View or Layout in its parent.

$haystack = array (
   'say hello',
   'hello stackoverflow',
   'hello world',
   'foo bar bas'
);

$matches  = preg_grep('/hello/i', $haystack);

print_r($matches);

Output

    [1] => say hello
    [2] => hello stackoverflow
    [3] => hello world
)

Although I agree this should be done server-side.

The solution to this problem is very simple...

If you don't have Ant build file then generate it. In Eclipse you can easily create a Ant file.

Refer to the link to create Ant build file [http://www.codejava.net/ides/eclipse/how-to-create-ant-build-file-for-existing-java-project-in-eclipse].

Now follow the given steps:

1) Add your Ant build file in Ant view that is in view window.

2) right click on your Ant build file and select Run As and the second option in that "Ant Build".

3) Now a dialog box will open with various options and tabs.

4) Select the JRE tab.

5) You will see three radio buttons and they will be having JRE or JDK selected as an option.

6) Look carefully if the radio button options are having JRE as selected then change it to JDK.

7) Click apply.

That's it...!!!

Marked answer does not work if triggered via button in worksheet. It opens Go To excel dialog box as CTRL+G is shortcut for. You have to SetFocus on Immediate Window before. You may need also DoEvent if you want to Debug.Print right after clearing.

Application.VBE.Windows("Immediate").SetFocus
Application.SendKeys "^g ^a {DEL}"
DoEvents

For completeness, as @Austin D noticed:

For those wondering, the shortcut keys are Ctrl+G (to activate the Immediate window), then Ctrl+A (to select everything), then Del (to clear it).

You can also install gems in your local environment (without sudo) with

gem install --user-install <gemname>

I recommend that so you don't mess with your system-level configuration even if it's a single-user computer.

You can check where the gems go by looking at gempaths with gem environment. In my case it's "~/.gem/ruby/1.8".

If you need some binaries from local installs added to your path, you can add something to your bashrc like:

if which ruby >/dev/null && which gem >/dev/null; then
    PATH="$(ruby -r rubygems -e 'puts Gem.user_dir')/bin:$PATH"
fi

(from http://guides.rubygems.org/faqs/#user-install)

No, AFAIK, it's not possible to do it portably.

There's no defined "first" record anyway - on different SQL engines it's perfectly possible that "SELECT * FROM table" might return the results in a different order each time.

I did debugging and finally returned my 'stuffed' query to it it's normal way.

Simply

select * from myTable for xml path('myTable')

gives me contents of the table to write to a log table from a trigger I debug.

According to ECMAScript6 ES6, the clean way is destructuring arrays:

const input = 'john smith~123 Street~Apt 4~New York~NY~12345';_x000D_
_x000D_
const [name, street, unit, city, state, zip] = input.split('~');_x000D_
_x000D_
console.log(name); // john smith_x000D_
console.log(street); // 123 Street_x000D_
console.log(unit); // Apt 4_x000D_
console.log(city); // New York_x000D_
console.log(state); // NY_x000D_
console.log(zip); // 12345

You may have extra items in the input string. In this case, you can use rest operator to get an array for the rest or just ignore them:

const input = 'john smith~123 Street~Apt 4~New York~NY~12345';_x000D_
_x000D_
const [name, street, ...others] = input.split('~');_x000D_
_x000D_
console.log(name); // john smith_x000D_
console.log(street); // 123 Street_x000D_
console.log(others); // ["Apt 4", "New York", "NY", "12345"]

I supposed a read-only reference for values and used the const declaration.

Enjoy ES6!

I prefer using the following method:

system.webServer>

  </defaultDocument>

Mongo DB requires space to store it files. So you should create folder structure for Mongo DB before starting the Mongodb server/client.

for e.g. MongoDb/Dbfiles where Mongo DB is installed.

Then in cmd promt exe mongod.exe and mongo.exe for client and done.

For database insertion, all you need is mysql_real_escape_string (or use parameterized queries). You generally don't want to alter data before saving it, which is what would happen if you used htmlentities. That would lead to a garbled mess later on when you ran it through htmlentities again to display it somewhere on a webpage.

Use htmlentities when you are displaying the data on a webpage somewhere.

Somewhat related, if you are sending submitted data somewhere in an email, like with a contact form for instance, be sure to strip newlines from any data that will be used in the header (like the From: name and email address, subect, etc)

$input = preg_replace('/\s+/', ' ', $input);

If you don't do this it's just a matter of time before the spam bots find your form and abuse it, I've learned the hard way.

I see there is a VBA solution and a non-VBA solution, which both are really good. I wanted to propose my Javascript solution.

There is an Excel add-in called Funfun that allows you to use javascript, HTML and css in Excel. It has an online editor with an embedded spreadsheet where you can build your chart.

I have written this code for you with Chart.js:

https://www.funfun.io/1/#/edit/5a61ed15404f66229bda3f44

To create this chart, I entered my data on the spreadsheet and read it with a json file, it is the short file.

I make sure to put it in the right format, in script.js, so I can add it to my chart:

var data = [];
var color = [];
var label = [];

for (var i = 1; i < $internal.data.length; i++)
{
    label.push($internal.data[i][0]);
    data.push([$internal.data[i][1], $internal.data[i][2]]);
    color.push($internal.data[i][3]);
}

I then create the scatter chart with each dot having his designated color and position:

 var dataset = [];
  for (var i = 0; i < data.length; i++) {   
    dataset.push({
      data: [{
        x: data[i][0],
        y: data[i][1] 
      }],
      pointBackgroundColor: color[i],
      pointStyle: "cercle",
      radius: 6  
    });
  }

After I've created my scatter chart I can upload it in Excel by pasting the URL in the funfun Excel add-in. Here is how it looks like with my example:

Once this is done You can change the color or the position of a dot instantly, in Excel, by changing the values in the spreadsheet.

If you want to add extra dots in the charts you just need to modify the radius of data in the short json file.

Hope this Javascript solution helps !

Disclosure : I’m a developer of funfun

First, you need to allocate array of pointers like char **c = malloc( N * sizeof( char* )), then allocate each row with a separate call to malloc, probably in the loop:

/* N is the number of rows  */
/* note: c is char** */
if (( c = malloc( N*sizeof( char* ))) == NULL )
{ /* error */ }

for ( i = 0; i < N; i++ )
{
  /* x_i here is the size of given row, no need to
   * multiply by sizeof( char ), it's always 1
   */
  if (( c[i] = malloc( x_i )) == NULL )
  { /* error */ }

  /* probably init the row here */
}

/* access matrix elements: c[i] give you a pointer
 * to the row array, c[i][j] indexes an element
 */
c[i][j] = 'a';

If you know the total number of elements (e.g. N*M) you can do this in a single allocation.

In Kotlin,

val drawable = ContextCompat.getDrawable(context, R.drawable.rating_filled)
val drawableHeight = drawable.intrinsicHeight

rating_bar.layoutParams.height = drawableHeight

DUMPBIN /EXPORTS Will get most of that information and hitting MSDN will get the rest.

The SimpleDateFormat class allows you to parse a String into a java.util.Date object. Once you have the Date object, you can get the milliseconds since the epoch by calling Date.getTime().

The full example:

String myDate = "2014/10/29 18:10:45";
//creates a formatter that parses the date in the given format
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = sdf.parse(myDate);
long timeInMillis = date.getTime();

Note that this gives you a long and not a double, but I think that's probably what you intended. The documentation for the SimpleDateFormat class has tons on information on how to set it up to parse different formats.

this is what you have to do.

decimal d = 1200.00;    
string value = d.ToString(CultureInfo.InvariantCulture);

// value = "1200.00" 

This worked for me. Thanks.

Com = commercial application (just like .com, most people register their app as a com app)
First level = always the publishing entity's' name
Second level (optional) = sub-devison, group, or project name
Final level = product name

For example he android launcher (home screen) is Com.Google.android.launcher

This question has been discussed quite thoroughly and I didn't get a chance to read all the responses. But here's few things to take into consideration while looking at the upper limit on number of simultaneous threads that can co-exist peacefully in a given system.

1. Thread Stack Size : In Linux the default thread stack size is 8MB (you can use ulimit -a to find it out).
2. Max Virtual memory that a given OS variant supports. Linux Kernel 2.4 supports a memory address space of 2 GB. with Kernel 2.6 , I a bit bigger (3GB )
3. [1] shows the calculations for the max number of threads per given Max VM Supported. For 2.4 it turns out to be about 255 threads. for 2.6 the number is a bit larger.
4. What kindda kernel scheduler you have . Comparing Linux 2.4 kernel scheduler with 2.6 , the later gives you a O(1) scheduling with no dependence upon number of tasks existing in a system while first one is more of a O(n). So also the SMP Capabilities of the kernel schedule also play a good role in max number of sustainable threads in a system.

Now you can tune your stack size to incorporate more threads but then you have to take into account the overheads of thread management(creation/destruction and scheduling). You can enforce CPU Affinity to a given process as well as to a given thread to tie them down to specific CPUs to avoid thread migration overheads between the CPUs and avoid cold cash issues.

Note that one can create thousands of threads at his/her wish , but when Linux runs out of VM it just randomly starts killing processes (thus threads). This is to keep the utility profile from being maxed out. (The utility function tells about system wide utility for a given amount of resources. With a constant resources in this case CPU Cycles and Memory, the utility curve flattens out with more and more number of tasks ).

I am sure windows kernel scheduler also does something of this sort to deal with over utilization of the resources

There are lots of good answers already for this question. However nowadays Route configuration is sort of "deprecated". The newer version of MVC (.NET Core) does not support it. So better to get use to it :)

So I agree with all the answers which uses Attribute style routing. But I keep noticing that everyone repeated the base part of the route (api/...). It is better to apply a [RoutePrefix] attribute on top of the Controller class and don't repeat the same string over and over again.

[RoutePrefix("api/customers")]
public class MyController : Controller
{
 [HttpGet]
 public List<Customer> Get()
 {
   //gets all customer logic
 }

 [HttpGet]
 [Route("currentMonth")]
 public List<Customer> GetCustomerByCurrentMonth()
 {
     //gets some customer 
 }

 [HttpGet]
 [Route("{id}")]
 public Customer GetCustomerById(string id)
 {
  //gets a single customer by specified id
 }
 [HttpGet]
 [Route("customerByUsername/{username}")]
 public Customer GetCustomerByUsername(string username)
 {
    //gets customer by its username
 }
}

Just 2 simple steps to solve your issue

First of all check AppendDataBoundItems property and make it assign false

Secondly clear all the items using property .clear()

{
ddl1.Items.Clear();
ddl1.datasource = sql1;
ddl1.DataBind();
}

//Simple function that will tell if the function is defined or not
function is_function(func) {
    return typeof window[func] !== 'undefined' && $.isFunction(window[func]);
}

//usage

if (is_function("myFunction") {
        alert("myFunction defined");
    } else {
        alert("myFunction not defined");
    }

Unobtrusive Javascript has many many advantages, here are the steps it takes and why it's good to use.

1. the link loads as normal:

   <a id="DaLink" href="http://host/toAnewPage.html">click here</a>

this is important becuase it will work for browsers with javascript not enabled, or if there is an error in the javascript code that doesn't work.

2. javascript runs on page load:

    window.onload = function(){
           document.getElementById("DaLink").onclick = function(){
                  if(funcitonToCall()){
                      // most important step in this whole process
                      return false;
                  }
           }
    }
   

3. if the javascript runs successfully, maybe loading the content in the current page with javascript, the return false cancels the link firing. in other words putting return false has the effect of disabling the link if the javascript ran successfully. While allowing it to run if the javascript does not, making a nice backup so your content gets displayed either way, for search engines and if your code breaks, or is viewed on an non-javascript system.

best book on the subject is "Dom Scription" by Jeremy Keith

The answer with

<div 
    className="player"
    onKeyDown={this.onKeyPressed}
    tabIndex={0}
>

works for me, please note that the tabIndex requires a number, not a string, so tabIndex="0" doesn't work.

Just wanted to share my experience as well. My Build had crossed Processing Step(it was a mere 984kB app) but did not show up in "Versions" tab for more than 30 minutes. I also double checked my email but had not received anything from Apple. However, under versions tab I had 3 builds listed excluding the latest one. What worked for me was that I just clicked on the least recent one(click on the Build Number) and then clicked on Expire Build and voila buy recent Build was immediately available under the current Version.

I have not found any Apple Document which explains this anomaly.

Hope it Helps! Cheers

Instead of installing a library inside Jupyter, I would recommend you use the 'Dark Reader' extension in Chrome (you can find 'Dark Reader' extension in other browsers, e.g. Firefox). You can play with it; filter the URL(s) you want to have dark theme, or even how define the Dark theme for yourself. Below are couple of examples:

I hope it helps.

Solved my issue in Ubuntu 14.04 OS with python 2.7.6, by adding below two lines into ~/.bash_profile (or ~/.bashrc in unix) files.

source "/usr/local/bin/virtualenvwrapper.sh"

export WORKON_HOME="/opt/virtual_env/"

And then executing both these lines onto the terminal.

if you have this problem and are on api level 21+ do this:

   map = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map))
                    .getMap();

this will get the map when used inside of a fragment.

This works for all edge cases. The weird calculation for newMonth handles negative months input. If the new month does not match the expected month (like 31 Feb), it will set the day of month to 0, which translates to "end of previous month":

function dateAddCalendarMonths(date, months) {
    monthSum = date.getMonth() + months;
    newMonth = (12 + (monthSum % 12)) % 12;
    newYear = date.getFullYear() + Math.floor(monthSum / 12);
    newDate = new Date(newYear, newMonth, date.getDate());
    return (newDate.getMonth() != newMonth)
        ? new Date(newDate.setDate(0))
        : newDate;
}

In order to write into a file in Python, we need to open it in write w, append a or exclusive creation x mode.

We need to be careful with the w mode, as it will overwrite into the file if it already exists. Due to this, all the previous data are erased.

Writing a string or sequence of bytes (for binary files) is done using the write() method. This method returns the number of characters written to the file.

with open('Failed.py','w',encoding = 'utf-8') as f:
   f.write("Write what you want to write in\n")
   f.write("this file\n\n")

This program will create a new file named Failed.py in the current directory if it does not exist. If it does exist, it is overwritten.

We must include the newline characters ourselves to distinguish the different lines.

Try disclose: https://github.com/pmq20/disclose

disclose essentially makes a self-extracting exe out of your Node.js project and Node.js interpreter with the following characteristics,

1. No GUI. Pure CLI.
2. No run-time dependencies
3. Supports both Windows and Unix
4. Runs slowly for the first time (extracting to a cache dir), then fast forever

Try node-compiler: https://github.com/pmq20/node-compiler

I have made a new project called node-compiler to compile your Node.js project into one single executable.

It is better than disclose in that it never runs slowly for the first time, since your source code is compiled together with Node.js interpreter, just like the standard Node.js libraries.

Additionally, it redirect file and directory requests transparently to the memory instead of to the file system at runtime. So that no source code is required to run the compiled product.

How it works: https://speakerdeck.com/pmq20/node-dot-js-compiler-compiling-your-node-dot-js-application-into-a-single-executable

Comparing with Similar Projects,

• pkg(https://github.com/zeit/pkg): Pkg hacked fs.* API's dynamically in order to access in-package files, whereas Node.js Compiler leaves them alone and instead works on a deeper level via libsquash. Pkg uses JSON to store in-package files while Node.js Compiler uses the more sophisticated and widely used SquashFS as its data structure.

• EncloseJS(http://enclosejs.com/): EncloseJS restricts access to in-package files to only five fs.* API's, whereas Node.js Compiler supports all fs.* API's. EncloseJS is proprietary licensed and charges money when used while Node.js Compiler is MIT-licensed and users are both free to use it and free to modify it.

• Nexe(https://github.com/nexe/nexe): Nexe does not support dynamic require because of its use of browserify, whereas Node.js Compiler supports all kinds of require including require.resolve.

• asar(https://github.com/electron/asar): Asar uses JSON to store files' information while Node.js Compiler uses SquashFS. Asar keeps the code archive and the executable separate while Node.js Compiler links all JavaScript source code together with the Node.js virtual machine and generates a single executable as the final product.

• AppImage(http://appimage.org/): AppImage supports only Linux with a kernel that supports SquashFS, while Node.js Compiler supports all three platforms of Linux, macOS and Windows, meanwhile without any special feature requirements from the kernel.

This error means that file was not found. Either path is wrong or file is not present where you want it to be. Try to access it by entering source address in your browser to check if it really is there. Browse the directories on server to ensure the path is correct. You may even copy and paste the relative path to be certain it is alright.

You can initialize a list of string and add those items that are selected.

Please check code, works fine for me.

List<string> modules = new List<string>();

foreach(ListItem s in chk_modules.Items)
{
    if (s.Selected)
    {
         modules.Add(s.Value);
    }
}

my problem was with the accents (á É ñ ) and the plus sign (+) when i to try to save javascript "code examples" to mysql:

my solution (not the better way, but it works):

javascript:

function replaceAll( text, busca, reemplaza ){
  while (text.toString().indexOf(busca) != -1)
  text = text.toString().replace(busca,reemplaza);return text;
}


function cleanCode(cod){
code = replaceAll(cod , "|", "{1}" ); // error | palos de explode en java
code = replaceAll(code, "+", "{0}" ); // error con los signos mas   
return code;
}

function to save:

function save(pid,code){
code = cleanCode(code); // fix sign + and |
code = escape(code); // fix accents
var url = 'editor.php';
var variables = 'op=save';
var myData = variables +'&code='+ code +'&pid='+ pid +'&newdate=' +(new Date()).getTime();    
var result = null;
$.ajax({
datatype : "html",
data: myData,  
url: url,
success : function(result) {
    alert(result); // result ok                     
},
}); 
} // end function

function in php:

<?php
function save($pid,$code){
    $code= preg_replace("[\{1\}]","|",$code);
    $code= preg_replace("[\{0\}]","+",$code);
    mysql_query("update table set code= '" . mysql_real_escape_string($code) . "' where pid='$pid'");
}
?>

You can use XmlDocument and for manipulating or retrieve data from attributes you can Linq to XML classes.

If you want to catch the event from the starting of the swipe you can use MotionEvent.ACTION_MOVE and store the first value to compare

I consider state to be for view only information and data that should persist beyond the view state is better stored as props. URL params are useful when you want to be able to link to a page or share the URL deep in to the app but otherwise clutter the address bar.

Take a look at Redux-Persist (if you're using redux) https://github.com/rt2zz/redux-persist

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

Another answer with later print/format style is:

res[0]=12
res[1]=23
print("my num is 0x{0:02x}{1:02x}".format(res[0],res[1]))

Yes. Have a look at Wikipedia and Cloanto Implementation of INI File Format (see bottom of page).

If you have cloned using HTTPS (recommended) then:-

git config --global credential.helper cache

and then

git config --global credential.helper 'cache --timeout=2592000'

• timeout=2592000 (30 Days in seconds) to enable caching for 30 days (or whatever suites you).

• Now run a simple git command that requires your username and password.

• Enter your credentials once and now caching is enabled for 30 Days.

• Try again with any git command and now you don't need any credentials.

• For more info :- Caching your GitHub password in Git

Note : You need Git 1.7.10 or newer to use the credential helper. On system restart, we might have to enter the password again.

Update #1:

If you are receiving this error git: 'credential-cache' is not a git command. See 'get --help'

then replace git config --global credential.helper 'cache --timeout=2592000'

with git config --global credential.helper 'store --file ~/.my-credentials'

Update #2:

If you keep getting the prompt of username and password and getting this issue:

Logon failed, use ctrl+c to cancel basic credential prompt.

Reinstalling the latest version of git worked for me.

Adding to the solution of array.slice(); be aware that if you have multidimensional array sub-arrays will be copied by references. What you can do is to loop and slice() each sub-array individually

var arr = [[1,1,1],[2,2,2],[3,3,3]];
var arr2 = arr.slice();

arr2[0][1] = 55;
console.log(arr2[0][1]);
console.log(arr[0][1]);

function arrCpy(arrSrc, arrDis){
 for(elm in arrSrc){
  arrDis.push(arrSrc[elm].slice());
}
}

var arr3=[];
arrCpy(arr,arr3);

arr3[1][1] = 77;

console.log(arr3[1][1]);
console.log(arr[1][1]);

same things goes to array of objects, they will be copied by reference, you have to copy them manually

.toDate did not really work for me, So, Here is what i did :

futureStartAtDate = new Date(moment().locale("en").add(1, 'd').format("MMM DD, YYYY HH:MM"))

hope this helps

This work on all browser to get pasted value. And also to creating common method for all text box.

$("#textareaid").bind("paste", function(e){

} )

With jsonlint (like xmllint):

aptitude install python-demjson
jsonlint -f foo.json

Use function + 9 for HP laptops. Others keys specified in previous answers didn't work for me.

Another simple routine.

def flatten_columns(df, sep='.'):
    def _remove_empty(column_name):
        return tuple(element for element in column_name if element)
    def _join(column_name):
        return sep.join(column_name)

    new_columns = [_join(_remove_empty(column)) for column in df.columns.values]
    df.columns = new_columns

There's one difference — which shouldn't matter — that the other answers haven't touched on, so:

There's no difference that's likely to matter, no. Yes, there is a very small difference.

If the fulfillment handler passed to then throws, the promise returned by that call to then is rejected with what was thrown.

If it returns a rejected promise, the promise returned by the call to then is resolved to that promise (and will ultimately be rejected, since the promise it's resolved to is rejected), which may introduce one extra async "tick" (one more loop in the microtask queue, to put it in browser terms).

Any code that relies on that difference is fundamentally broken, though. :-) It shouldn't be that sensitive to the timing of the promise settlement.

Here's an example:

function usingThrow(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                throw new Error(`${v} is not 42!`);
            }
            return v;
        });
}
function usingReject(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                return Promise.reject(new Error(`${v} is not 42!`));
            }
            return v;
        });
}

// The rejection handler on this chain may be called **after** the
// rejection handler on the following chain
usingReject(1)
.then(v => console.log(v))
.catch(e => console.error("Error from usingReject:", e.message));

// The rejection handler on this chain may be called **before** the
// rejection handler on the preceding chain
usingThrow(2)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

If you run that, as of this writing you get:

Error from usingThrow: 2 is not 42!
Error from usingReject: 1 is not 42!

Note the order.

Compare that to the same chains but both using usingThrow:

function usingThrow(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                throw new Error(`${v} is not 42!`);
            }
            return v;
        });
}

usingThrow(1)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

usingThrow(2)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

which shows that the rejection handlers ran in the other order:

Error from usingThrow: 1 is not 42!
Error from usingThrow: 2 is not 42!

I said "may" above because there's been some work in other areas that removed this unnecessary extra tick in other similar situations if all of the promises involved are native promises (not just thenables). (Specifically: In an async function, return await x originally introduced an extra async tick vs. return x while being otherwise identical; ES2020 changed it so that if x is a native promise, the extra tick is removed.)

Again, any code that's that sensitive to the timing of the settlement of a promise is already broken. So really it doesn't/shouldn't matter.

In practical terms, as other answers have mentioned:

• As Kevin B pointed out, throw won't work if you're in a callback to some other function you've used within your fulfillment handler — this is the biggie
• As lukyer pointed out, throw abruptly terminates the function, which can be useful (but you're using return in your example, which does the same thing)
• As Vencator pointed out, you can't use throw in a conditional expression (? :), at least not for now

Other than that, it's mostly a matter of style/preference, so as with most of those, agree with your team what you'll do (or that you don't care either way), and be consistent.

In my case: I forgot to activate virtualenv

I installed "pip install example" in the wrong virtualenv

Just browse up to your installation's directory and execute this file "pg_env.bat", so after go at bin folder and execute pgAdmin.exe. This must work no doubt!

There may simply not be such a guide. If so, you may not have much luck convincing anybody to write one, because it would be a lot of work.

I would recommend either of two things. The easier one is to follow the guide you have slavishly, which means forgetting about msysgit.

The harder one is to put up a Linux server - perhaps as a guest under Windows using VirtualBox (free) or VMWare or Parallels (pay), and then follow one of the many sets of instructions Google will lead you to. But you will probably find those instructions are insufficient - they usually assume you've already set up an ssh server, for example, so you have to get that info elsewhere. I've done that twice, and can say that unless you're already something of a Linux guru, it will be a struggle.

You have a lot of pointless jQuery in there, but the $compile service is actually super simple in this case:

.directive( 'test', function ( $compile ) {
  return {
    restrict: 'E',
    scope: { text: '@' },
    template: '<p ng-click="add()">{{text}}</p>',
    controller: function ( $scope, $element ) {
      $scope.add = function () {
        var el = $compile( "<test text='n'></test>" )( $scope );
        $element.parent().append( el );
      };
    }
  };
});

You'll notice I refactored your directive too in order to follow some best practices. Let me know if you have questions about any of those.

This worked for me:

For the HTML, add the required attribute to the input element

<input class="my-input-element" type="text" placeholder="" required />

For the CSS, use the :invalid selector to target the empty input

input.my-input-element:invalid {

}

Notes:

• About required from w3Schools.com: "When present, it specifies that an input field must be filled out before submitting the form."

   $base_url="http://".$_SERVER['SERVER_NAME'].dirname($_SERVER["REQUEST_URI"].'?').'/';

Usage:

print "<script src='{$base_url}js/jquery.min.js'/>";

I did not get it. I had a similar problem but in my nav bar.

What I was doing is I kept my navBar code in this way: nav>div.navlinks>ul>li*3>a

In order to put hover effects on a I positioned a to relative and designed a::before and a::after then i put a gray background on before and after elements and kept hover effects in such way that as one hovers on <a> they will pop from outside a to fill <a>.

The problem is that the overflow hidden is not working on <a>.

What i discovered is if i removed <li> and simply put <a> without <ul> and <li> then it worked.

What may be the problem?

Apache Commons

    for (Date dateIter = fromDate; !dateIter.after(toDate); dateIter = DateUtils.addDays(dateIter, 1)) {
        // ...
    }

The following should work:

ABC: *\([a-zA-Z]+\) *(.+)

Explanation:

ABC:            # match literal characters 'ABC:'
 *              # zero or more spaces
\([a-zA-Z]+\)   # one or more letters inside of parentheses
 *              # zero or more spaces
(.+)            # capture one or more of any character (except newlines)

To get your desired grouping based on the comments below, you can use the following:

(ABC:) *(\([a-zA-Z]+\).+)

these methods can help setTitle("your new title"); or super("your new title");

TL;DR

Summary; if you have binary (non-alphanumeric) data (or a significantly sized payload) to transmit, use multipart/form-data. Otherwise, use application/x-www-form-urlencoded.

The MIME types you mention are the two Content-Type headers for HTTP POST requests that user-agents (browsers) must support. The purpose of both of those types of requests is to send a list of name/value pairs to the server. Depending on the type and amount of data being transmitted, one of the methods will be more efficient than the other. To understand why, you have to look at what each is doing under the covers.

For application/x-www-form-urlencoded, the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be: 

MyVariableOne=ValueOne&MyVariableTwo=ValueTwo

According to the specification:

[Reserved and] non-alphanumeric characters are replaced by `%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character

That means that for each non-alphanumeric byte that exists in one of our values, it's going to take three bytes to represent it. For large binary files, tripling the payload is going to be highly inefficient.

That's where multipart/form-data comes in. With this method of transmitting name/value pairs, each pair is represented as a "part" in a MIME message (as described by other answers). Parts are separated by a particular string boundary (chosen specifically so that this boundary string does not occur in any of the "value" payloads). Each part has its own set of MIME headers like Content-Type, and particularly Content-Disposition, which can give each part its "name." The value piece of each name/value pair is the payload of each part of the MIME message. The MIME spec gives us more options when representing the value payload -- we can choose a more efficient encoding of binary data to save bandwidth (e.g. base 64 or even raw binary).

Why not use multipart/form-data all the time? For short alphanumeric values (like most web forms), the overhead of adding all of the MIME headers is going to significantly outweigh any savings from more efficient binary encoding.

<div id="demo"></div>

<input type="submit" name="submit" id="submit" value="Submit" onClick="return empty()">


<script type="text/javascript">
        function empty()
        {
          var x;
          x = document.getElementById("feedbackpost").value;
          if (x == "")
           {
             var demo = document.getElementById("demo");
             demo.innerHTML =document.write='<h1>Hello member</h1>';
              return false;
           };
        }
    </script>

Probably the easiest way would be use this app Hosts Editor . You need to have root

This article thoroughly explains the difference between different implementations of Python. Like the article puts it:

The first thing to realize is that ‘Python’ is an interface. There’s a specification of what Python should do and how it should behave (as with any interface). And there are multiple implementations (as with any interface).

The second thing to realize is that ‘interpreted’ and ‘compiled’ are properties of an implementation, not an interface.

Yet another answer is Yet Another Java Service Wrapper, this seems like a good alternative to Java Service Wrapper as has better licensing. It is also intended to be easy to move from JSW to YAJSW. Certainly for me, brand new to windows servers and trying to get a Java app running as a service, it was very easy to use.

Some others I found, but didn't end up using:

• Java Service Launcher I didn't use this because it looked more complicated to get working than YAJSW. I don't think this is a wrapper.
• JSmooth Creating Window's services isn't its primary goal, but can be done. I didn't use this because there's been no activity since 2007.

Java has a special static method:

public static void main(String[] args) { ... }

which is executed in a class when the class is started with a java command line:

$ java Class

would execute said method in the class "Class" if it existed.

public void run() { ... }

is required by the Runnable interface, or inherited from the Thread class when creating new threads.

None of the others worked for me. I had to add the following dependency, as explained here

compile group: 'cz.msebera.android' , name: 'httpclient', version: '4.4.1.1'

because I was targeting API 23.

DateTime.Now.Tostring();

. You can supply parameters to To string function in a lot of ways like given in this link http://www.geekzilla.co.uk/View00FF7904-B510-468C-A2C8-F859AA20581F.htm

This will be a lot useful. If you reside somewhere else than the regular format (MM/dd/yyyy)

use always MM not mm, mm gives minutes and MM gives month.

You can skip the container or background image with pure css arrow:

select {

  /* make arrow and background */

  background:
    linear-gradient(45deg, transparent 50%, blue 50%),
    linear-gradient(135deg, blue 50%, transparent 50%),
    linear-gradient(to right, skyblue, skyblue);
  background-position:
    calc(100% - 21px) calc(1em + 2px),
    calc(100% - 16px) calc(1em + 2px),
    100% 0;
  background-size:
    5px 5px,
    5px 5px,
    2.5em 2.5em;
  background-repeat: no-repeat;

  /* styling and reset */

  border: thin solid blue;
  font: 300 1em/100% "Helvetica Neue", Arial, sans-serif;
  line-height: 1.5em;
  padding: 0.5em 3.5em 0.5em 1em;

  /* reset */

  border-radius: 0;
  margin: 0;      
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  -webkit-appearance:none;
  -moz-appearance:none;
}

Sample here

in my case this is the solution to fix it. When you create a project select MinGW GCC from the Toolchains panel.

Once the project is created, select project file, press ctrl + b to build the project. Then hit run and the the output should be printed on the console.

Most answers here are not correct as they would add bottom space to the last <li> as well, so they are not adding space ONLY in between <li> !

The most accurate and efficient solution is the following:

li.menu-item:not(:last-child) { 
   margin-bottom: 3px;  
}

Explanation: by using :not(:last-child) the style will be applie to all items (li.menu-item) but the last one.

DOMNodeInserted is being deprecated, along with the other DOM mutation events, because of performance issues - the recommended approach is to use a MutationObserver to watch the DOM. It's only supported in newer browsers though, so you should fall back onto DOMNodeInserted when MutationObserver isn't available.

let observer = new MutationObserver((mutations) => {
  mutations.forEach((mutation) => {
    if (!mutation.addedNodes) return

    for (let i = 0; i < mutation.addedNodes.length; i++) {
      // do things to your newly added nodes here
      let node = mutation.addedNodes[i]
    }
  })
})

observer.observe(document.body, {
    childList: true
  , subtree: true
  , attributes: false
  , characterData: false
})

// stop watching using:
observer.disconnect()

As mentioned before

iterator.remove()

is maybe the only safe way to remove list items during the loop.

For deeper understanding of items removal using the iterator, try to look at this thread

I was having the exact same problem. I found the issue within bootstrap.min.css. You need to change the label: label {display:inline-block;} to label {display:block;}

In views with {{}} and/or ng-model, Angular is setting up $watch()es for you behind the scenes.

By default $watch compares by reference. If you set the third parameter to $watch to true, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:

$scope.$watch('myModel', function() { ... }, true);

Update: Angular v1.2 added a new method for this, `$watchCollection():

$scope.$watchCollection('myModel', function() { ... });

Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.

The reference for the user-specific configuration for Maven is available on-line and it doesn't make much sense to share a settings.xml with you since these settings are user specific.

If you need to configure a proxy, have a look at the section about Proxies.

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0

  </proxies>
  ...
</settings>

• id: The unique identifier for this proxy. This is used to differentiate between proxy elements.
• active: true if this proxy is active. This is useful for declaring a set of proxies, but only one may be active at a time.
• protocol, host, port: The protocol://host:port of the proxy, seperated into discrete elements.
• username, password: These elements appear as a pair denoting the login and password required to authenticate to this proxy server.
• nonProxyHosts: This is a list of hosts which should not be proxied. The delimiter of the list is the expected type of the proxy server; the example above is pipe delimited - comma delimited is also common

Go to projects menu, click on clean menu item.

After that close the eclipse and reopen and try compiling..

It is software glitch you find some times.

It took me a while to find the answer to this question. Most people seem to be suggesting regex solutions. I strongly prefer to use code that is tried and tested as opposed to regex that I or someone else thought up on the fly.

I use the parseUri library available here: http://stevenlevithan.com/demo/parseuri/js/

It allows you to do exactly what you are asking for:

var uri = 'http://localhost/search.php?year=2008';
var year = uri.queryKey['year'];
// year = '2008'

public static void main(String[] args) {
          Scanner input =new Scanner(System.in);
          System.out.print("enter how many:");
         int num =input.nextInt();
    int[] arr= new int [num];
    for(int b=0;b<arr.length;b++){
   System.out.print("enter no." + (b+1) +"=");
   arr[b]=input.nextInt();
    }

    for (int i=0; i<arr.length;i++) {
        for (int k=i;k<arr.length;k++) {

        if(arr[i] > arr[k]) {

        int temp=arr[k];
        arr[k]=arr[i];
        arr[i]=temp;
        }
            }

    }
    System.out.println("******************\n output\t accending order");


    for (int i : arr){
        System.out.println(i);
    }
}
}

You can create a .htaccess file for the folder, wich should have denied access with

Deny from  all

or you can redirect to a custom 404 page

Redirect /includes/ 404.html

Just to clarify, and for anyone else that may be pulling their hair out...

If you are using git bash on Windows, set node_env=production&& node whatever.js does not seem to work. Instead, use the native cmd. Then, using set node_env=production&& node whatever.jsworks as expected.

My use case:

I develop on Windows because my workflow is a lot faster, but I needed to make sure that my application's development-specific middleware were not firing in the production environment.

If you want to find all records that are not NULL, and either empty or have any number of spaces, this will work:

LIKE '%\ '

Make sure that there's a space after the backslash. More info here: http://dev.mysql.com/doc/refman/5.0/en/string-comparison-functions.html

There seems to be quite a selection now. I was able to compile application in VS2015 using Visual Studio 2015 - Windows XP (v140_xp) setting. To make it actually run on Win XP I had to deploy (copy alongside application) msvcr100.dll for Release build and msvcr110.dll and msvcr100d.dll for Debug build (note there is a difference in numbers 100 and 110, also debug lib msvcr100d.dll may not be redistributable)

There are a couple of options there. The sample code is in Java, but a port to other languages should be straightforward.

Java:

WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = (WebElement) ((JavascriptExecutor) driver).executeScript(
                                   "return arguments[0].parentNode;", myElement);

XPath:

WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = myElement.findElement(By.xpath("./.."));

Obtaining the driver from the WebElement

Note: As you can see, for the JavaScript version you'll need the driver. If you don't have direct access to it, you can retrieve it from the WebElement using:

WebDriver driver = ((WrapsDriver) myElement).getWrappedDriver();

Percent encoding. Replace the hash with %23.

Use CSS's :disabled selector (for CSS3):

checkbox-style { }
checkbox-style:disabled { }

Or you need to use javascript to alter the style based on when you enable/disable it (Assuming it is being enabled/disabled based on your question).

I managed to solve the problem by placing the code in the .Rprofile file in the default working directory.

First, I found the location of the default working directory

> getwd()
[1] "C:/Users/me/Documents"

Then I used a text editor to write a simple .Rprofile file with the following line in it

.libPaths("C:/software/Rpackages")

Finally, when I start R and run .libPaths() I get the desired output:

> .libPaths()
[1] "C:/software/Rpackages"               "C:/Program Files/R/R-2.15.2/library"
[3] "C:/Program Files/RStudio/R/library"

The FOR loop worked well, I modified it a tiny bit:

#include<iostream>
using namespace std;
int main ()
{

    int sum = 0;
    int number;
    int numberitems;


    cout << "Enter number of items: \n";
    cin >> numberitems;

    for(int i=0;i<numberitems;i++)
    {
        cout << "Enter number: \n";
        cin >> number; 

        sum=sum+number;

    }
    cout<<"sum is: "<< sum<<endl;
}

HOWEVER, the WHILE loop has got some errors on line 11 (Count was not declared in this scope). What could be the issue? Also, if you would have a solution using DO,WHILE loop it would be wonderful. Thanks

To clear Application Data Please Try this way.

    public void clearApplicationData() {
    File cache = getCacheDir();
    File appDir = new File(cache.getParent());
    if (appDir.exists()) {
        String[] children = appDir.list();
        for (String s : children) {
            if (!s.equals("lib")) {
                deleteDir(new File(appDir, s));Log.i("TAG", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************");
            }
        }
    }
}

public static boolean deleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
    }

    return dir.delete();
}

The examples to os.walk in the documentation show how to do this:

for root, dirs, filenames in os.walk(indir):
    for f in filenames:
        log = open(os.path.join(root, f),'r')

How did you expect the "open" function to know that the string "1" is supposed to mean "/home/des/test/1" (unless "/home/des/test" happens to be your current working directory)?

Another way of setting the default to the HTML web forms editor is:

1. At the top menu in Visual Studio go to File > New > File
2. Select HTML Page
3. In the lower right corner of the New File dialog on the Open button there is a down arrow
4. Click it and you should see an option Open With
5. Select HTML (Web Forms) Editor
6. Click Set as Default
7. Press OK

If the set of possibilities is "compact" (i.e. largest-value - smallest-value is, say, less than 200) you might consider a lookup table. This would be especially useful if you had a structure like

if (x == 12 || x == 16 || x == 19 || ...)
else if (x==34 || x == 55 || ...)
else if (...)

Set up an array with values identifying the branch to be taken (1, 2, 3 in the example above) and then your tests become

switch(dispatchTable[x])
{
    case 1:
        ...
        break;
    case 2:
        ...
        break;
    case 3:
        ...
        break;
}

Whether or not this is appropriate depends on the semantics of the problem.

If an array isn't appropriate, you could use a Map<Integer,Integer>, or if you just want to test membership for a single statement, a Set<Integer> would do. That's a lot of firepower for a simple if statement, however, so without more context it's kind of hard to guide you in the right direction.

Use the Javascript string split() function.

var coolVar = '123-abc-itchy-knee';
var partsArray = coolVar.split('-');

// Will result in partsArray[0] == '123', partsArray[1] == 'abc', etc

Try this (see a working example of this code in jsfiddle: http://jsfiddle.net/periklis/7ATLS/1/)

<input type = "button" id = "clickme" value="Click me!"/>
<div id = "alert_placeholder"></div>
<script>
bootstrap_alert = function() {}
bootstrap_alert.warning = function(message) {
            $('#alert_placeholder').html('<div class="alert"><a class="close" data-dismiss="alert">×</a><span>'+message+'</span></div>')
        }

$('#clickme').on('click', function() {
            bootstrap_alert.warning('Your text goes here');
});
</script>?

EDIT: There are now libraries that simplify and streamline this process, such as bootbox.js

If s is your string than you could do it this way:

Mid(s, index, 1)

Edit based on comment below question.

It seems that you need a bit different approach which should be easier. Try in this way:

Dim character As String 'Integer if for numbers
's = ActiveDocument.Content.Text - we don't need it
character = Activedocument.Characters(index)

A TCP connection is specified by the tuple (source IP, source port, destination IP, destination port).

The reason why there is a TIME_WAIT state following session shutdown is because there may still be live packets out in the network on their way to you (or from you which may solicit a response of some sort). If you were to re-create that same tuple and one of those packets showed up, it would be treated as a valid packet for your connection (and probably cause an error due to sequencing).

So the TIME_WAIT time is generally set to double the packets maximum age. This value is the maximum age your packets will be allowed to get to before the network discards them.

That guarantees that, before you're allowed to create a connection with the same tuple, all the packets belonging to previous incarnations of that tuple will be dead.

That generally dictates the minimum value you should use. The maximum packet age is dictated by network properties, an example being that satellite lifetimes are higher than LAN lifetimes since the packets have much further to go.

For me what worked by combining all the posts I have read is:

1.Enable OLE automation - if not enabled

sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE;  
GO  
sp_configure 'Ole Automation Procedures', 1;  
GO  
RECONFIGURE;  
GO

2.Create a folder where the generated files will be stored:

C:\GREGTESTING

3.Create DocTable that will be used for file generation and store there the blobs in Doc_Content

CREATE TABLE [dbo].[Document](
    [Doc_Num] [numeric](18, 0) IDENTITY(1,1) NOT NULL,
    [Extension] [varchar](50) NULL,
    [FileName] [varchar](200) NULL,
    [Doc_Content] [varbinary](max) NULL   
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 

INSERT [dbo].[Document] ([Extension] ,[FileName] , [Doc_Content] )
    SELECT 'pdf', 'SHTP Notional hire - January 2019.pdf', 0x....(varbinary blob)

Important note!

Don't forget to add in Doc_Content column the varbinary of file you want to generate!

4.Run the below script

DECLARE @outPutPath varchar(50) = 'C:\GREGTESTING'
, @i bigint
, @init int
, @data varbinary(max) 
, @fPath varchar(max)  
, @folderPath  varchar(max)

--Get Data into temp Table variable so that we can iterate over it 
DECLARE @Doctable TABLE (id int identity(1,1), [Doc_Num]  varchar(100) , [FileName]  varchar(100), [Doc_Content] varBinary(max) )



INSERT INTO @Doctable([Doc_Num] , [FileName],[Doc_Content])
Select [Doc_Num] , [FileName],[Doc_Content] FROM  [dbo].[Document]



SELECT @i = COUNT(1) FROM @Doctable   

WHILE @i >= 1   

BEGIN    

SELECT 
    @data = [Doc_Content],
    @fPath = @outPutPath + '\' + [Doc_Num] +'_' +[FileName],
    @folderPath = @outPutPath + '\'+ [Doc_Num]
FROM @Doctable WHERE id = @i

EXEC sp_OACreate 'ADODB.Stream', @init OUTPUT; -- An instace created
EXEC sp_OASetProperty @init, 'Type', 1;  
EXEC sp_OAMethod @init, 'Open'; -- Calling a method
EXEC sp_OAMethod @init, 'Write', NULL, @data; -- Calling a method
EXEC sp_OAMethod @init, 'SaveToFile', NULL, @fPath, 2; -- Calling a method
EXEC sp_OAMethod @init, 'Close'; -- Calling a method
EXEC sp_OADestroy @init; -- Closed the resources
print 'Document Generated at - '+  @fPath   

--Reset the variables for next use
SELECT @data = NULL  
, @init = NULL
, @fPath = NULL  
, @folderPath = NULL
SET @i -= 1
END   

5.The results is shown below:

Please check this link. Which will allow animations like L2R, R2L, T2B, B2T animations.

This code shows animation from left to right

TranslateAnimation animate = new TranslateAnimation(0,view.getWidth(),0,0);
animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
view.setVisibility(View.GONE);

if you want to do it from R2L then use

TranslateAnimation animate = new TranslateAnimation(0,-view.getWidth(),0,0);

for top to bottom as

TranslateAnimation animate = new TranslateAnimation(0,0,0,view.getHeight());

and vice a versa..

In short, truncate doesn't log anything (so is much faster but can't be undone) whereas delete is logged (and can be part of a larger transaction, will rollback etc). If you have data that you don't want in a table in dev it is normally better to truncate as you don't run the risk of filling up the transaction log

I know the topic is old, but I just fell on it after a google search so... here is another solution:

$array_merged = array_merge($array_going_first, $array_going_second);

This one seems pretty clean to me, it works just fine!

I wouldn't use arrays. They're problematic for several reasons and you can't declare it in terms of a specific array size anyway. Try:

List<List<String>> addresses = new ArrayList<List<String>>();

But honestly for addresses, I'd create a class to model them.

If you were to use arrays it would be:

List<String[]> addresses = new ArrayList<String[]>();

ie you can't declare the size of the array.

Lastly, don't declare your types as concrete types in instances like this (ie for addresses). Use the interface as I've done above. This applies to member variables, return types and parameter types.

Leaving aside the technical issues with the code you posted, you asked this:

To use this Dictionary Items in a Table View i have to transfer it to a NSArray, am i right?

The answer to which is: not necessarily. There's nothing intrinsic to the machinery of UITableView, UITableViewDataSource, or UITableViewDelegate that means that your data has to be in an array. You will need to implement various methods to tell the system how many rows are in your table, and what data appears in each row. Many people find it much more natural and efficient to answer those questions with an ordered data structure like an array. But there's no requirement that you do so. If you can write the code to implement those methods with the dictionary you started with, feel free!

I'm using the same approach, I suggest to write the singleton a little better:

public static MyApp getInstance() {

    if (instance == null) {
        synchronized (MyApp.class) {
            if (instance == null) {
                instance = new MyApp ();
            }
        }
    }

    return instance;
}

but I'm not using everywhere, I use getContext() and getApplicationContext() where I can do it!

You have to workaround this via static application context accessor approach:

@Component
public class StaticContextAccessor {

    private static StaticContextAccessor instance;

    @Autowired
    private ApplicationContext applicationContext;

    @PostConstruct
    public void registerInstance() {
        instance = this;
    }

    public static <T> T getBean(Class<T> clazz) {
        return instance.applicationContext.getBean(clazz);
    }

}

Then you can access bean instances in a static manner.

public class Boo {

    public static void randomMethod() {
         StaticContextAccessor.getBean(Foo.class).doStuff();
    }

}

If you are compiling linux kernel. For example, if you want to disable the warning that is "unused-but-set-variable" been treated as error. You can add a statement:

KBUILD_CFLAGS += $(call cc-option,-Wno-error=unused-but-set-variable,)

in your Makefile

May I suggest a somewhat hacky but still genius solution! I got the idea from this article and adapted it for Android. Basically you use a WebView and insert the HTML you want to show and edit in an editable div tag. This way when the user taps the WebView the keyboard appears and allows editing. They you just add some JavaScript to get back the edited HTML and voila!

Here is the code:

public class HtmlTextEditor extends WebView {

    class JsObject {
        // This field always keeps the latest edited text
        public String text;
        @JavascriptInterface
        public void textDidChange(String newText) {
            text = newText.replace("\n", "");
        }
    }

    private JsObject mJsObject;

    public HtmlTextEditor(Context context, AttributeSet attrs) {
        super(context, attrs);

        getSettings().setJavaScriptEnabled(true);
        mJsObject = new JsObject();
        addJavascriptInterface(mJsObject, "injectedObject");
        setWebViewClient(new WebViewClient(){
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                loadUrl(
                        "javascript:(function() { " +
                            "    var editor = document.getElementById(\"editor\");" +
                            "    editor.addEventListener(\"input\", function() {" +
                            "        injectedObject.textDidChange(editor.innerHTML);" +
                            "    }, false)" +
                            "})()");
            }
        });
    }

    public void setText(String text) {
        if (text == null) { text = ""; }

        String editableHtmlTemplate = "<!DOCTYPE html>" + "<html>" + "<head>" + "<meta name=\"viewport\" content=\"initial-scale=1.0\" />" + "</head>" + "<body>" + "<div id=\"editor\" contenteditable=\"true\">___REPLACE___</div>" + "</body>" + "</html>";
        String editableHtml = editableHtmlTemplate.replace("___REPLACE___", text);
        loadData(editableHtml, "text/html; charset=utf-8", "UTF-8");
        // Init the text field in case it's read without editing the text before
        mJsObject.text = text;
    }

    public String getText() {
        return mJsObject.text;
    }
}

And here is the component as a Gist.

Note: I didn't need the height change callback from the original solution so that's missing here but you can easily add it if needed.

A unit test is done in (as far as possible) total isolation.

An integration test is done when the tested object or module is working like it should be, with other bits of code.

Just Override the boolean equals() method of custom object. Say you have an ArrayList with custom field f1, f2, ... override

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (!(o instanceof CustomObject)) return false;

    CustomObject object = (CustomObject) o;

    if (!f1.equals(object.dob)) return false;
    if (!f2.equals(object.fullName)) return false;
    ...
    return true;
}

and check using ArrayList instance's contains() method. That's it.

The MOST IMPORTANT THING I didn't understand for quite awhile is that the request MUST contain "callback=JSON_CALLBACK", because AngularJS modifies the request url, substituting a unique identifier for "JSON_CALLBACK". The server response must use the value of the 'callback' parameter instead of hard coding "JSON_CALLBACK":

JSON_CALLBACK(json_response);  // wrong!

Since I was writing my own PHP server script, I thought I knew what function name it wanted and didn't need to pass "callback=JSON_CALLBACK" in the request. Big mistake!

AngularJS replaces "JSON_CALLBACK" in the request with a unique function name (like "callback=angular.callbacks._0"), and the server response must return that value:

angular.callbacks._0(json_response);

A hackish perl solution can be like this. It's nice because it doesn't load all the file in memory, prints intermediate temp files, and then uses the all-wonderful paste

#!/usr/bin/perl
use warnings;
use strict;

my $counter;
open INPUT, "<$ARGV[0]" or die ("Unable to open input file!");
while (my $line = <INPUT>) {
    chomp $line;
    my @array = split ("\t",$line);
    open OUTPUT, ">temp$." or die ("unable to open output file!");
    print OUTPUT join ("\n",@array);
    close OUTPUT;
    $counter=$.;
}
close INPUT;

# paste files together
my $execute = "paste ";
foreach (1..$counter) {
    $execute.="temp$counter ";
}
$execute.="> $ARGV[1]";
system $execute;

If the worksheet you want to retrieve exists at compile-time in ThisWorkbook (i.e. the workbook that contains the VBA code you're looking at), then the simplest and most consistently reliable way to refer to that Worksheet object is to use its code name:

Debug.Print Sheet1.Range("A1").Value

You can set the code name to anything you need (as long as it's a valid VBA identifier), independently of its "tab name" (which the user can modify at any time), by changing the (Name) property in the Properties toolwindow (F4):

The Name property refers to the "tab name" that the user can change on a whim; the (Name) property refers to the code name of the worksheet, and the user can't change it without accessing the Visual Basic Editor.

VBA uses this code name to automatically declare a global-scope Worksheet object variable that your code gets to use anywhere to refer to that sheet, for free.

In other words, if the sheet exists in ThisWorkbook at compile-time, there's never a need to declare a variable for it - the variable is already there!

If the worksheet is created at run-time (inside ThisWorkbook or not), then you need to declare & assign a Worksheet variable for it.

Use the Worksheets property of a Workbook object to retrieve it:

Dim wb As Workbook
Set wb = Application.Workbooks.Open(path)

Dim ws As Worksheet
Set ws = wb.Worksheets(nameOrIndex)

Important notes...

• Both the name and index of a worksheet can easily be modified by the user (accidentally or not), unless workbook structure is protected. If workbook isn't protected, you simply cannot assume that the name or index alone will give you the specific worksheet you're after - it's always a good idea to validate the format of the sheet (e.g. verify that cell A1 contains some specific text, or that there's a table with a specific name, that contains some specific column headings).

• Using the Sheets collection contains Worksheet objects, but can also contain Chart instances, and a half-dozen more legacy sheet types that are not worksheets. Assigning a Worksheet reference from whatever Sheets(nameOrIndex) returns, risks throwing a type mismatch run-time error for that reason.

• Not qualifying the Worksheets collection is an implicit ActiveWorkbook reference - meaning the Worksheets collection is pulling from whatever workbook is active at the moment the instruction is executing. Such implicit references make the code frail and bug-prone, especially if the user can navigate and interact with the Excel UI while code is running.

• Unless you mean to activate a specific sheet, you never need to call ws.Activate in order to do 99% of what you want to do with a worksheet. Just use your ws variable instead.

After reviewing all the other answers, I ended up with this:

function oldSchoolMakeBuild(cb) {
    var makeProcess = exec('make -C ./oldSchoolMakeBuild',
         function (error, stdout, stderr) {
             stderr && console.error(stderr);
             cb(error);
        });
    makeProcess.stdout.on('data', function(data) {
        process.stdout.write('oldSchoolMakeBuild: '+ data);
    });
}

Sometimes data will be multiple lines, so the oldSchoolMakeBuild header will appear once for multiple lines. But this didn't bother me enough to change it.

A complex filter condition is better in performance perspective, but the best performance will show old fashion for loop with a standard if clause is the best option. The difference on a small array 10 elements difference might ~ 2 times, for a large array the difference is not that big.
You can take a look on my GitHub project, where I did performance tests for multiple array iteration options

For small array 10 element throughput ops/s: For medium 10,000 elements throughput ops/s: For large array 1,000,000 elements throughput ops/s:

UPDATE: Java 11 has some progress on the performance, but the dynamics stay the same

According to documentation of $viewContentLoaded, it supposed to work

Emitted every time the ngView content is reloaded.

$viewContentLoaded event is emitted that means to receive this event you need a parent controller like

<div ng-controller="MainCtrl">
  <div ng-view></div>
</div>

From MainCtrl you can listen the event

  $scope.$on('$viewContentLoaded', function(){
    //Here your view content is fully loaded !!
  });

The other answers are totally fine:

• One does not need a special syntax to support generics in Python
• Python uses duck typing as pointed out by André.

However, if you still want a typed variant, there is a built-in solution since Python 3.5.

Generic classes:

from typing import TypeVar, Generic

T = TypeVar('T')

class Stack(Generic[T]):
    def __init__(self) -> None:
        # Create an empty list with items of type T
        self.items: List[T] = []

    def push(self, item: T) -> None:
        self.items.append(item)

    def pop(self) -> T:
        return self.items.pop()

    def empty(self) -> bool:
        return not self.items

# Construct an empty Stack[int] instance
stack = Stack[int]()
stack.push(2)
stack.pop()
stack.push('x')        # Type error

Generic functions:

from typing import TypeVar, Sequence

T = TypeVar('T')      # Declare type variable

def first(seq: Sequence[T]) -> T:
    return seq[0]

def last(seq: Sequence[T]) -> T:
    return seq[-1]


n = first([1, 2, 3])  # n has type int.

Reference: mypy documentation about generics.

A much easier way is to go to Data and select Group or Subtotal. Instant collapsible rows without messing with pivot tables or VBA.

By design make parser executes lines in a separate shell invocations, that's why changing variable (e.g. PATH) in one line, the change may not be applied for the next lines (see this post).

One way to workaround this problem, is to convert multiple commands into a single line (separated by ;), or use One Shell special target (.ONESHELL, as of GNU Make 3.82).

Alternatively you can provide PATH variable at the time when shell is invoked. For example:

PATH  := $(PATH):$(PWD)/bin:/my/other/path
SHELL := env PATH=$(PATH) /bin/bash

Another way to change color of a button if you want to do multiple operations along with color change. Using the Tk().after method and binding a change method allows you to change color and do other operations.

Label.destroy is another example of the after method.

    def export_win():
        //Some Operation
        orig_color = export_finding_graph.cget("background")
        export_finding_graph.configure(background = "green")

        tt = "Exported"
        label = Label(tab1_closed_observations, text=tt, font=("Helvetica", 12))
        label.grid(row=0,column=0,padx=10,pady=5,columnspan=3)

        def change(orig_color):
            export_finding_graph.configure(background = orig_color)

        tab1_closed_observations.after(1000, lambda: change(orig_color))
        tab1_closed_observations.after(500, label.destroy)


    export_finding_graph = Button(tab1_closed_observations, text='Export', command=export_win)
    export_finding_graph.grid(row=6,column=4,padx=70,pady=20,sticky='we',columnspan=3)

You can also revert to the original color.

Based on docker documentation: https://docs.docker.com/compose/compose-file/#/command

I simply put hostname: <string> in my docker-compose file.

E.g.:

[...]

lb01:
  hostname: at-lb01
  image: at-client-base:v1

[...]

and container lb01 picks up at-lb01 as hostname.

In Short

A stack is used for static memory allocation and a heap for dynamic memory allocation, both stored in the computer's RAM.

In Detail

The Stack

The stack is a "LIFO" (last in, first out) data structure, that is managed and optimized by the CPU quite closely. Every time a function declares a new variable, it is "pushed" onto the stack. Then every time a function exits, all of the variables pushed onto the stack by that function, are freed (that is to say, they are deleted). Once a stack variable is freed, that region of memory becomes available for other stack variables.

The advantage of using the stack to store variables, is that memory is managed for you. You don't have to allocate memory by hand, or free it once you don't need it any more. What's more, because the CPU organizes stack memory so efficiently, reading from and writing to stack variables is very fast.

The Heap

The heap is a region of your computer's memory that is not managed automatically for you, and is not as tightly managed by the CPU. It is a more free-floating region of memory (and is larger). To allocate memory on the heap, you must use malloc() or calloc(), which are built-in C functions. Once you have allocated memory on the heap, you are responsible for using free() to deallocate that memory once you don't need it any more.

If you fail to do this, your program will have what is known as a memory leak. That is, memory on the heap will still be set aside (and won't be available to other processes). As we will see in the debugging section, there is a tool called Valgrind that can help you detect memory leaks.

Unlike the stack, the heap does not have size restrictions on variable size (apart from the obvious physical limitations of your computer). Heap memory is slightly slower to be read from and written to, because one has to use pointers to access memory on the heap. We will talk about pointers shortly.

Unlike the stack, variables created on the heap are accessible by any function, anywhere in your program. Heap variables are essentially global in scope.

Variables allocated on the stack are stored directly to the memory and access to this memory is very fast, and its allocation is dealt with when the program is compiled. When a function or a method calls another function which in turns calls another function, etc., the execution of all those functions remains suspended until the very last function returns its value. The stack is always reserved in a LIFO order, the most recently reserved block is always the next block to be freed. This makes it really simple to keep track of the stack, freeing a block from the stack is nothing more than adjusting one pointer.

Variables allocated on the heap have their memory allocated at run time and accessing this memory is a bit slower, but the heap size is only limited by the size of virtual memory. Elements of the heap have no dependencies with each other and can always be accessed randomly at any time. You can allocate a block at any time and free it at any time. This makes it much more complex to keep track of which parts of the heap are allocated or free at any given time.

You can use the stack if you know exactly how much data you need to allocate before compile time, and it is not too big. You can use the heap if you don't know exactly how much data you will need at runtime or if you need to allocate a lot of data.

In a multi-threaded situation each thread will have its own completely independent stack, but they will share the heap. The stack is thread specific and the heap is application specific. The stack is important to consider in exception handling and thread executions.

Each thread gets a stack, while there's typically only one heap for the application (although it isn't uncommon to have multiple heaps for different types of allocation).

At run-time, if the application needs more heap, it can allocate memory from free memory and if the stack needs memory, it can allocate memory from free memory allocated memory for the application.

Even, more detail is given here and here.

Now come to your question's answers.

To what extent are they controlled by the OS or language runtime?

The OS allocates the stack for each system-level thread when the thread is created. Typically the OS is called by the language runtime to allocate the heap for the application.

What is their scope?

Already given in top.

"You can use the stack if you know exactly how much data you need to allocate before compile time, and it is not too big. You can use the heap if you don't know exactly how much data you will need at runtime or if you need to allocate a lot of data."

More can be found in here.

What determines the size of each of them?

The size of the stack is set by OS when a thread is created. The size of the heap is set on application startup, but it can grow as space is needed (the allocator requests more memory from the operating system).

What makes one faster?

Stack allocation is much faster since all it really does is move the stack pointer. Using memory pools, you can get comparable performance out of heap allocation, but that comes with a slight added complexity and its own headaches.

Also, stack vs. heap is not only a performance consideration; it also tells you a lot about the expected lifetime of objects.

First check if you have configured JDK correctly:

• Go to File->Project Structure -> SDKs
• your JDK home path should be something like this: /Library/Java/JavaVirtualMachine/jdk.1.7.0_79.jdk/Contents/Home
• Hit Apply and then OK

Secondly check if you have provided in path in Library's section

• Go to File->Project Structure -> Libraries
• Hit the + button
• Add the path to your src folder
• Hit Apply and then OK

This should fix the problem

I ran into the same problem and after a couple of hours of logging and investigating, I fixed it.

It turned out that for the first time the value is set in a date picker, $viewValue is a string so the dateFilter displays it as is. All I did is parse it into a Date object.

Search for that block in ui-bootstrap-tpls file

  ngModel.$render = function() {
    var date = ngModel.$viewValue ? dateFilter(ngModel.$viewValue, dateFormat) : '';
    element.val(date);

    updateCalendar();
  };

and replace it by:

  ngModel.$render = function() {
    ngModel.$viewValue = new Date(ngModel.$viewValue);
    var date = ngModel.$viewValue ? dateFilter(ngModel.$viewValue, dateFormat) : '';
    element.val(date);

    updateCalendar();
  };

Hopefully this will help :)
