Thanks Nicholas Carey. I was going to use regex first but what you wrote changed my mind. It is so much easier to maintain this way.

//You can set these from your custom service methods
int minLen = 8;
int minDigit 2;
int minSpChar 2;

Boolean ErrorFlag = false;
//Check for password length
if (model.NewPassword.Length < minLen)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must be at least " + minLen + " characters long.");
}

//Check for Digits and Special Characters
int digitCount = 0;
int splCharCount = 0;
foreach (char c in model.NewPassword)
{
    if (char.IsDigit(c)) digitCount++;
    if (Regex.IsMatch(c.ToString(), @"[!#$%&'()*+,-.:;<=>?@[\\\]{}^_`|~]")) splCharCount++;
}

if (digitCount < minDigit)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minDigit + " digit(s).");
}
if (splCharCount < minSpChar)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minSpChar + " special character(s).");
}

if (ErrorFlag)
    return View(model);

You can use strstream. It's formally deprecated, but it's still a great tool if you need to work with C strings, i think.

char result[100]; // max size 100
std::ostrstream s(result, sizeof result - 1);

s << one << two << std::ends;
result[99] = '\0';

This will write one and then two into the stream, and append a terminating \0 using std::ends. In case both strings could end up writing exactly 99 characters - so no space would be left writing \0 - we write one manually at the last position.

You can use a turn-around and just deploy the application into tomcat server: just copy/paste under the webapps folder. Once tomcat is started, it will create a folder with the app name and you can access the contents directly

only start listner then u can connect with database. command run on editor:

lsnrctl start

its work fine.

To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file

"compilerOptions": {
    "noUnusedLocals": true,
    "noUnusedParameters": true
}

have the typescript compiler installed, ifnot install it with:

npm install -g typescript

and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.

I would also recomend using typescript hero extension for organizing your imports.

• SYSDATE provides date and time of a server.
• CURRENT_DATE provides date and time of client.(i.e., your system)
• CURRENT_TIMESTAMP provides data and timestamp of a clinet.

Try this one from Codeproject (credit to Nitron):

I think it's the same dialog you're talking about - maybe it would help if you add a screenshot?

bool GetFolder(std::string& folderpath, const char* szCaption=NULL, HWND hOwner=NULL)
{
    bool retVal = false;

    // The BROWSEINFO struct tells the shell how it should display the dialog.
    BROWSEINFO bi;
    memset(&bi, 0, sizeof(bi));

    bi.ulFlags   = BIF_USENEWUI;
    bi.hwndOwner = hOwner;
    bi.lpszTitle = szCaption;

    // must call this if using BIF_USENEWUI
    ::OleInitialize(NULL);

    // Show the dialog and get the itemIDList for the selected folder.
    LPITEMIDLIST pIDL = ::SHBrowseForFolder(&bi);

    if(pIDL != NULL)
    {
        // Create a buffer to store the path, then get the path.
        char buffer[_MAX_PATH] = {'\0'};
        if(::SHGetPathFromIDList(pIDL, buffer) != 0)
        {
            // Set the string value.
            folderpath = buffer;
            retVal = true;
        }       

        // free the item id list
        CoTaskMemFree(pIDL);
    }

    ::OleUninitialize();

    return retVal;
}

Method that returns locale from string exists in commons-lang library: LocaleUtils.toLocale(localeAsString)

There are so many good answers here already, but i just want to show with an example that you can add additional functionality to the class being extended;

function applyMixins(derivedCtor: any, baseCtors: any[]) {
    baseCtors.forEach(baseCtor => {
        Object.getOwnPropertyNames(baseCtor.prototype).forEach(name => {
            if (name !== 'constructor') {
                derivedCtor.prototype[name] = baseCtor.prototype[name];
            }
        });
    });
}

class Class1 {
    doWork() {
        console.log('Working');
    }
}

class Class2 {
    sleep() {
        console.log('Sleeping');
    }
}

class FatClass implements Class1, Class2 {
    doWork: () => void = () => { };
    sleep: () => void = () => { };


    x: number = 23;
    private _z: number = 80;

    get z(): number {
        return this._z;
    }

    set z(newZ) {
        this._z = newZ;
    }

    saySomething(y: string) {
        console.log(`Just saying ${y}...`);
    }
}
applyMixins(FatClass, [Class1, Class2]);


let fatClass = new FatClass();

fatClass.doWork();
fatClass.saySomething("nothing");
console.log(fatClass.x);

I answered this question in another post:

How to get list of changed files since last build in Jenkins/Hudson

#!/bin/bash

set -e

job_name="whatever"
JOB_URL="http://myserver:8080/job/${job_name}/"
FILTER_PATH="path/to/folder/to/monitor"

python_func="import json, sys
obj = json.loads(sys.stdin.read())
ch_list = obj['changeSet']['items']
_list = [ j['affectedPaths'] for j in ch_list ]
for outer in _list:
  for inner in outer:
    print inner
"

_affected_files=`curl --silent ${JOB_URL}${BUILD_NUMBER}'/api/json' | python -c "$python_func"`

if [ -z "`echo \"$_affected_files\" | grep \"${FILTER_PATH}\"`" ]; then
  echo "[INFO] no changes detected in ${FILTER_PATH}"
  exit 0
else
  echo "[INFO] changed files detected: "
  for a_file in `echo "$_affected_files" | grep "${FILTER_PATH}"`; do
    echo "    $a_file"
  done;
fi;

You can add the check directly to the top of the job's exec shell, and it will exit 0 if no changes are detected... Hence, you can always poll the top level for check-in's to trigger a build.

Use conditional formatting.

You can enter a condition using any cell you like and a format to apply if the formula is true.

You could use a nested query:

Select
  ColumnA,
  ColumnB,
  calccolumn1,
  calccolumn1 / ColumnC as calccolumn2
From (
  Select
    ColumnA,
    ColumnB,
    ColumnC,
    ColumnA + ColumnB As calccolumn1
  from t42
);

With a row with values 3, 4, 5 that gives:

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4

You can also just repeat the first calculation, unless it's really doing something expensive (via a function call, say):

Select
  ColumnA,
  ColumnB,
  ColumnA + ColumnB As calccolumn1,
  (ColumnA + ColumnB) / ColumnC As calccolumn2
from t42; 

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4 

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

Use a FULL OUTER JOIN:

select 
   a.col_a,
   a.col_b,
   b.col_c
from
   (select col_a,col_bfrom tab1) a
join 
   (select col_a,col_cfrom tab2) b 
on a.col_a= b.col_a

An alternative to cat() is writeLines():

> writeLines("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename
>

An advantage is that you don't have to remember to append a "\n" to the string passed to cat() to get a newline after your message. E.g. compare the above to the same cat() output:

> cat("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename>

and

> cat("File not supplied.\nUsage: ./program F=filename","\n")
File not supplied.
Usage: ./program F=filename
>

The reason print() doesn't do what you want is that print() shows you a version of the object from the R level - in this case it is a character string. You need to use other functions like cat() and writeLines() to display the string. I say "a version" because precision may be reduced in printed numerics, and the printed object may be augmented with extra information, for example.

This is a state-of-the-union answer as of Windows PowerShell v5.1 / PowerShell Core v6.2.0:

• Andrew Savinykh's ill-fated answer, despite being the accepted one, is, as of this writing, fundamentally flawed (I do hope it gets fixed - there's enough information in the comments - and in the edit history - to do so).

• Ansgar Wiecher's helpful answer works well, but requires direct use of the .NET Framework (and reads the entire file into memory, though that could be changed). Direct use of the .NET Framework is not a problem per se, but is harder to master for novices and hard to remember in general.

• A future version of PowerShell Core will have a
  Convert-TextFile cmdlet with a -LineEnding parameter to allow in-place updating of text files with a specific newline style, as being discussed on GitHub.

In PSv5+, PowerShell-native solutions are now possible, because Set-Content now supports the -NoNewline switch, which prevents undesired appending of a platform-native newline^[1] :

# Convert CRLFs to LFs only.
# Note:
#  * (...) around Get-Content ensures that $file is read *in full*
#    up front, so that it is possible to write back the transformed content
#    to the same file.
#  * + "`n" ensures that the file has a *trailing LF*, which Unix platforms
#     expect.
((Get-Content $file) -join "`n") + "`n" | Set-Content -NoNewline $file

The above relies on Get-Content's ability to read a text file that uses any combination of CR-only, CRLF, and LF-only newlines line by line.

Caveats:

• You need to specify the output encoding to match the input file's in order to recreate it with the same encoding. The command above does NOT specify an output encoding; to do so, use -Encoding; without -Encoding:

  • In Windows PowerShell, you'll get "ANSI" encoding, your system's single-byte, 8-bit legacy encoding, such as Windows-1252 on US-English systems.
  • In PowerShell Core, you'll get UTF-8 encoding without a BOM.

• The input file's content as well as its transformed copy must fit into memory as a whole, which can be problematic with large input files.

• There's a risk of file corruption, if the process of writing back to the input file gets interrupted.

^{[1] In fact, if there are multiple strings to write, -NoNewline also doesn't place a newline between them; in the case at hand, however, this is irrelevant, because only one string is written.}

Hi,

Well, I have tried the methods mentioned above! it's working yes, but not exactly the way I wanted. I wanted to redirect the default page extension to the main domain with our further action.

Here how I do that...

# Accesible Index Page
<IfModule dir_module>
 DirectoryIndex index.php index.html
 RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.(html|htm|php|php3|php5|shtml|phtml) [NC]
 RewriteRule ^index\.html|htm|php|php3|php5|shtml|phtml$ / [R=301,L]
</IfModule>

The above code simply captures any index.* and redirect it to the main domain.

Thank you

I ran into this problem with templated classes. Here's a more general solution I had to use:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // Friend means operator<< can use private variables
    // It needs to be declared as a template, but T is taken
    template <class U>
    friend std::ostream& operator<<(std::ostream&, const myClass<U> &);
}

// Operator is a non-member and global, so it's not myClass<U>::operator<<()
// Because of how C++ implements templates the function must be
// fully declared in the header for the linker to resolve it :(
template <class U>
std::ostream& operator<<(std::ostream& os, const myClass<U> & obj)
{
  obj.toString(os);
  return os;
}

Now: * My toString() function can't be inline if it is going to be tucked away in cpp. * You're stuck with some code in the header, I couldn't get rid of it. * The operator will call the toString() method, it's not inlined.

The body of operator<< can be declared in the friend clause or outside the class. Both options are ugly. :(

Maybe I'm misunderstanding or missing something, but just forward-declaring the operator template doesn't link in gcc.

This works too:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // For some reason this requires using T, and not U as above
    friend std::ostream& operator<<(std::ostream&, const myClass<T> &)
    {
        obj.toString(os);
        return os;
    }
}

I think you can also avoid the templating issues forcing declarations in headers, if you use a parent class that is not templated to implement operator<<, and use a virtual toString() method.

Inside Edittext just arrange like this


<EditText
    android:id="@+id/editStWt1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:imeOptions="actionNext" //now its going to rightside/next field automatically
    ..........
    .......

</EditText>

js> s = "http://www.example.com/string with + and ? and & and spaces";
http://www.example.com/string with + and ? and & and spaces
js> encodeURI(s)
http://www.example.com/string%20with%20+%20and%20?%20and%20&%20and%20spaces
js> encodeURIComponent(s)
http%3A%2F%2Fwww.example.com%2Fstring%20with%20%2B%20and%20%3F%20and%20%26%20and%20spaces

Looks like encodeURI produces a "safe" URI by encoding spaces and some other (e.g. nonprintable) characters, whereas encodeURIComponent additionally encodes the colon and slash and plus characters, and is meant to be used in query strings. The encoding of + and ? and & is of particular importance here, as these are special chars in query strings.

You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).

Your code could be like:

const myArray = [  
   {  
      "id":25,
      "name":"Anakin Skywalker",
      "createdAt":"2017-04-12T12:48:55.000Z",
      "updatedAt":"2017-04-12T12:48:55.000Z"
   },
   {  
      "id":1,
      "name":"Luke Skywalker",
      "createdAt":"2017-04-12T11:25:03.000Z",
      "updatedAt":"2017-04-12T11:25:03.000Z"
   }
]

const myOrderedArray = _.sortBy(myArray, o => o.name)

Try to use the function DECODE

Ex: Decode(MYDATE, NULL, ' ', MYDATE)

If date is NULL then display ' ' (BLANK) else display the date.

Only providing .ttf file for webfont won't be good enough for cross-browser support. The best possible combination at present is using the combination as :

@font-face {
  font-family: 'MyWebFont';
  src: url('webfont.eot'); /* IE9 Compat Modes */
  src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('webfont.woff') format('woff'), /* Modern Browsers */
       url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}

This code assumes you have .eot , .woff , .ttf and svg format for you webfont. To automate all this process , you can use : Transfonter.org.

Also , modern browsers are shifting towards .woff font , so you can probably do this too : :

@font-face {
  font-family: 'MyWebFont';
  src: url('myfont.woff') format('woff'), /* Chrome 6+, Firefox 3.6+, IE 9+, Safari 5.1+ */
   url('myfont.ttf') format('truetype'); /* Chrome 4+, Firefox 3.5, Opera 10+, Safari 3—5 */
}

If the user does not pass the full path to the file (on Unix type systems this means a path that starts with a slash), the path is interpreted relatively to the current working directory. The current working directory usually is the directory in which you started the program. In your case, the file test.rtf must be in the same directory in which you execute the program.

You are obviously performing programming tasks in Python under Mac OS. There, I recommend to work in the terminal (on the command line), i.e. start the terminal, cd to the directory where your input file is located and start the Python script there using the command

$ python script.py

In order to make this work, the directory containing the python executable must be in the PATH, a so-called environment variable that contains directories that are automatically used for searching executables when you enter a command. You should make use of this, because it simplifies daily work greatly. That way, you can simply cd to the directory containing your Python script file and run it.

In any case, if your Python script file and your data input file are not in the same directory, you always have to specify either a relative path between them or you have to use an absolute path for one of them.

My SQL teacher said that if you specify both a DEFAULT value and NOT NULLor NULL, DEFAULT should always be expressed before NOT NULL or NULL.

Like this:

ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT "MyDefault" NOT NULL

ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT "MyDefault" NULL

With CentOS, you can do it using a combination of fastcgi for one version of PHP, and php-fpm for the other, as described here:

https://web.archive.org/web/20130707085630/http://linuxplayer.org/2011/05/intall-multiple-version-of-php-on-one-server

Based on CentOS 5.6, for Apache only

1. Enable rpmforge and epel yum repository

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
wget http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
sudo rpm -ivh rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
sudo rpm -ivh epel-release-5-4.noarch.rpm

2. Install php-5.1

CentOS/RHEL 5.x series have php-5.1 in box, simply install it with yum, eg:

sudo yum install php php-mysql php-mbstring php-mcrypt

3. Compile and install php 5.2 and 5.3 from source

For php 5.2 and 5.3, we can find many rpm packages on the Internet. However, they all conflict with the php which comes with CentOS, so, we’d better build and install them from soure, this is not difficult, the point is to install php at different location.

However, when install php as an apache module, we can only use one version of php at the same time. If we need to run different version of php on the same server, at the same time, for example, different virtual host may need different version of php. Fortunately, the cool FastCGI and PHP-FPM can help.

Build and install php-5.2 with fastcgi enabled

1) Install required dev packages

yum install gcc libxml2-devel bzip2-devel zlib-devel \
    curl-devel libmcrypt-devel libjpeg-devel \
    libpng-devel gd-devel mysql-devel

2) Compile and install

wget http://cn.php.net/get/php-5.2.17.tar.bz2/from/this/mirror
tar -xjf php-5.2.17.tar.bz2
cd php-5.2.17
./configure --prefix=/usr/local/php52 \
    --with-config-file-path=/etc/php52 \
    --with-config-file-scan-dir=/etc/php52/php.d \
    --with-libdir=lib64 \
    --with-mysql \
    --with-mysqli \
    --enable-fastcgi \
    --enable-force-cgi-redirect \
    --enable-mbstring \
    --disable-debug \
    --disable-rpath \
    --with-bz2 \
    --with-curl \
    --with-gettext \
    --with-iconv \
    --with-openssl \
    --with-gd \
    --with-mcrypt \
    --with-pcre-regex \
    --with-zlib
make -j4 > /dev/null
sudo make install
sudo mkdir /etc/php52
sudo cp php.ini-recommended /etc/php52/php.ini

3) create a fastcgi wrapper script

create file /usr/local/php52/bin/fcgiwrapper.sh

#!/bin/bash
PHP_FCGI_MAX_REQUESTS=10000
export PHP_FCGI_MAX_REQUESTS
exec /usr/local/php52/bin/php-cgi
chmod a+x /usr/local/php52/bin/fcgiwrapper.sh
Build and install php-5.3 with fpm enabled

wget http://cn.php.net/get/php-5.3.6.tar.bz2/from/this/mirror
tar -xjf php-5.3.6.tar.bz2 
cd php-5.3.6

Configue php-fpm

Edit /etc/php53/php-fpm.conf, change some settings. This step is mainly to uncomment some settings, you can adjust the value if you like.

pid = run/php-fpm.pid
listen = 127.0.0.1:9000
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 20

Then, start fpm

sudo /etc/init.d/php-fpm start

Install and setup mod_fastcgi, mod_fcgid

sudo yum install libtool httpd-devel apr-devel
wget http://www.fastcgi.com/dist/mod_fastcgi-current.tar.gz
tar -xzf mod_fastcgi-current.tar.gz
cd mod_fastcgi-2.4.6
cp Makefile.AP2 Makefile
sudo make top_dir=/usr/lib64/httpd/ install
sudo sh -c "echo 'LoadModule fastcgi_module modules/mod_fastcgi.so' > /etc/httpd/conf.d/mod_fastcgi.conf"
yum install mod_fcgid

Setup and test virtual hosts

1) Add the following line to /etc/hosts

127.0.0.1 web1.example.com web2.example.com web3.example.com

2) Create web document root and drop an index.php under it to show phpinfo switch to user root, run

mkdir /var/www/fcgi-bin
for i in {1..3}; do
    web_root=/var/www/web$i
    mkdir $web_root
    echo "<?php phpinfo(); ?>" > $web_root/index.php
done

Note: The empty /var/www/fcgi-bin directory is required, DO NOT REMOVE IT LATER

3) Create Apache config file(append to httpd.conf)

NameVirtualHost *:80

4) restart apache. visit the 3 sites respectly to view phpinfo and validate the result. ie:

http://web1.example.com
http://web2.example.com
http://web3.example.com

If all OK, you can use one of the 3 virtual host as template to create new virtual host, with the desired php version.

Here is my solution.

Tested with IE, Opera, Chrome, FireFox, Safari, as Phonegap WebApp on IOS 8 and as Phonegap WebApp on Android 4.4.2

This solution isn't working with FireFox on localhost.

You can do shortcut via inline function if you want to simply change the state variable without declaring a new function at top:

I had the same problem today. My persistence.xml was in the wrong location. I had to put it in the following path:

project/src/main/resources/META-INF/persistence.xml

Hive supports bigint literal since 0.8 version. So, additional "L" is enough:

COALESCE(column, 0L)

with this globals variables idea, I saved MainActivity instance in onCreate(); Android global variable

public class ApplicationController extends Application {

    public static MainActivity this_MainActivity;
}

and Open dialog like this. it worked.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Global Var
    globals = (ApplicationController) this.getApplication();
    globals.this_MainActivity = this;
}

and in a thread, I open dialog like this.

AlertDialog.Builder alert = new AlertDialog.Builder(globals.this_MainActivity);

1. Open MainActivity
2. Start a thread.
3. Open dialog from thread -> work.
4. Click "Back button" ( onCreate will be called and remove first MainActivity)
5. New MainActivity will start. ( and save it's instance to globals )
6. Open dialog from first thread --> it will open and work.

From XML

In case if you have the web-address/URL displayed on your view and you want it to make it clikable and direct user to particular website You can use:

android:autoLink="web"

In same way you can use different attributes of autoLink(email, phone, map, all) to accomplish your task...

You want the (standard) POSIXt type from base R that can be had in 'compact form' as a POSIXct (which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt (which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)

Quick example:

R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10  # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
 POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))
$sec
[1] 11.79

$min
[1] 39

$hour
[1] 18

$mday
[1] 25

$mon
[1] 11

$year
[1] 109

$wday
[1] 5

$yday
[1] 358

$isdst
[1] 0

attr(,"tzone")
[1] "America/Chicago" "CST"             "CDT"            
R> 

As for reading them in, see help(strptime)

As for difference, easy too:

R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")
Time difference of 51.25 weeks

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

by now the mounting works on some machines (ubuntu) and some doesn't (centos 7) but installing the plugin solves it

vagrant plugin install vagrant-vbguest

without having to do anything else on top of that, just

vagrant reload

Tips to make android studio fast:

Enable Offline Work:

1. Click File -> Settings. Search for "gradle" and click in Offline work box.
2. Go to Compiler (in same settings dialog just below Gradle) and add --offline to Command-line Options text box.

Improve Gradle Performance

gradle can be optimized too. The easy way is to modify the settings in global gradle.properties (create it if not exists in the following folders: Windows - C:\users\your_name\.gradle\; Linux- /home/<username>/.gradle/; Mac- /Users/<username>/.gradle/; ) and in that file, add these two lines:

org.gradle.daemon=true
org.gradle.parallel=true

If you have an image imported as a resource in your project there is also this:

picPreview.Image = Properties.Resources.ImageName;

Where picPreview is the name of the picture box and ImageName is the name of the file you want to display.

*Resources are located by going to: Project --> Properties --> Resources

A bit late answer, but I suggest you have a look at a not well known project on codeplex called ConferenceXP

ConferenceXP is an open source research platform that provides simple, flexible, and extensible conferencing and collaboration using high-bandwidth networks and the advanced multimedia capabilities of Microsoft Windows. ConferenceXP helps researchers and educators develop innovative applications and solutions that feature broadcast-quality audio and video in support of real-time distributed collaboration and distance learning environments.

Full source (it's huge!) is provided. It implements the RTP protocol.

Follow these steps to resolve:

Build > Publish > Profile > New

Create a new profile and configure it with the same settings as your existing profile.

The project will now publish correctly. This often occurs as a result of a source-controlled publish profile from another machine that was created in a newer version of Visual Studio.

The Function adds gaussian , salt-pepper , poisson and speckle noise in an image

Parameters
----------
image : ndarray
    Input image data. Will be converted to float.
mode : str
    One of the following strings, selecting the type of noise to add:

    'gauss'     Gaussian-distributed additive noise.
    'poisson'   Poisson-distributed noise generated from the data.
    's&p'       Replaces random pixels with 0 or 1.
    'speckle'   Multiplicative noise using out = image + n*image,where
                n is uniform noise with specified mean & variance.


import numpy as np
import os
import cv2
def noisy(noise_typ,image):
   if noise_typ == "gauss":
      row,col,ch= image.shape
      mean = 0
      var = 0.1
      sigma = var**0.5
      gauss = np.random.normal(mean,sigma,(row,col,ch))
      gauss = gauss.reshape(row,col,ch)
      noisy = image + gauss
      return noisy
   elif noise_typ == "s&p":
      row,col,ch = image.shape
      s_vs_p = 0.5
      amount = 0.004
      out = np.copy(image)
      # Salt mode
      num_salt = np.ceil(amount * image.size * s_vs_p)
      coords = [np.random.randint(0, i - 1, int(num_salt))
              for i in image.shape]
      out[coords] = 1

      # Pepper mode
      num_pepper = np.ceil(amount* image.size * (1. - s_vs_p))
      coords = [np.random.randint(0, i - 1, int(num_pepper))
              for i in image.shape]
      out[coords] = 0
      return out
  elif noise_typ == "poisson":
      vals = len(np.unique(image))
      vals = 2 ** np.ceil(np.log2(vals))
      noisy = np.random.poisson(image * vals) / float(vals)
      return noisy
  elif noise_typ =="speckle":
      row,col,ch = image.shape
      gauss = np.random.randn(row,col,ch)
      gauss = gauss.reshape(row,col,ch)        
      noisy = image + image * gauss
      return noisy

There is no generic type which will tell the compiler that a method returns nothing.

I believe the convention is to use Object when inheriting as a type parameter

OR

Propagate the type parameter up and then let users of your class instantiate using Object and assigning the object to a variable typed using a type-wildcard ?:

interface B<E>{ E method(); }

class A<T> implements B<T>{

    public T method(){
        // do something
        return null;
    }
}

A<?> a = new A<Object>();

Calculating Distance between Latitude and Longitude points...

        double Lat1 = Convert.ToDouble(latitude);
        double Long1 = Convert.ToDouble(longitude);

        double Lat2 = 30.678;
        double Long2 = 45.786;
        double circumference = 40000.0; // Earth's circumference at the equator in km
        double distance = 0.0;
        double latitude1Rad = DegreesToRadians(Lat1);
        double latititude2Rad = DegreesToRadians(Lat2);
        double longitude1Rad = DegreesToRadians(Long1);
        double longitude2Rad = DegreesToRadians(Long2);
        double logitudeDiff = Math.Abs(longitude1Rad - longitude2Rad);
        if (logitudeDiff > Math.PI)
        {
            logitudeDiff = 2.0 * Math.PI - logitudeDiff;
        }
        double angleCalculation =
            Math.Acos(
              Math.Sin(latititude2Rad) * Math.Sin(latitude1Rad) +
              Math.Cos(latititude2Rad) * Math.Cos(latitude1Rad) * Math.Cos(logitudeDiff));
        distance = circumference * angleCalculation / (2.0 * Math.PI);
        return distance;

$midnight = strtotime('midnight'); is valid
You can also try out strtotime('12am') or strtotime('[input any time you wish to here. e.g noon, 6pm, 3pm, 8pm, etc]'). I skipped adding today before midnight because the default is today.

You're comparing strings. JavaScript compares the ASCII code for each character of the string.

To see why you get false, look at the charCodes:

"1300".charCodeAt(0);
49
"999".charCodeAt(0);
57

The comparison is false because, when comparing the strings, the character codes for 1 is not greater than that of 9.

The fix is to treat the strings as numbers. You can use a number of methods:

parseInt(string, radix)
parseInt("1300", 10);
> 1300 - notice the lack of quotes


+"1300"
> 1300


Number("1300")
> 1300

Functional component approach (Minimal Demo, Full Demo):

import React, { useState } from "react";
import { useAsyncEffect } from "use-async-effect2";
import cpFetch from "cp-fetch"; //cancellable c-promise fetch wrapper

export default function TestComponent(props) {
  const [text, setText] = useState("");

  useAsyncEffect(
    function* () {
      setText("fetching...");
      const response = yield cpFetch(props.url);
      const json = yield response.json();
      setText(`Success: ${JSON.stringify(json)}`);
    },
    [props.url]
  );

  return <div>{text}</div>;
}

Class component (Live demo)

import { async, listen, cancel, timeout } from "c-promise2";
import cpFetch from "cp-fetch";

export class TestComponent extends React.Component {
  state = {
    text: ""
  };

  @timeout(5000)
  @listen
  @async
  *componentDidMount() {
    console.log("mounted");
    const response = yield cpFetch(this.props.url);
    this.setState({ text: `json: ${yield response.text()}` });
  }

  render() {
    return <div>{this.state.text}</div>;
  }

  @cancel()
  componentWillUnmount() {
    console.log("unmounted");
  }
}

If it's inside a closure, i'm pretty sure you can't.

Otherwise you just do functionName(); and hit return.

In Linux use below command to upload code in git
1 ) git clone repository
ask for user name and password.
2) got to respositiory directory.
3) git add project name.
4) git commit -m ' messgage '.
5) git push origin master.
- user name ,password

Update new Change code into Github

->Goto Directory That your github up code
->git commit ProjectName -m 'Message'
->git push origin master.

Sometimes, this error occurs when you're trying to target an element that is wrapped in a condition, for example: <div *ngIf="canShow"> <p #target>Targeted Element</p></div>

In this code, if canShow is false on render, Angular won't be able to get that element as it won't be rendered, hence the error that comes up.

One of the solutions is to use a display: hidden on the element instead of the *ngIf so the element gets rendered but is hidden until your condition is fulfilled.

If you're using SQL Server, you can set the value of bit fields with 0 and 1

or

'true' and 'false' (yes, using strings)

...your_bit_field='false'... => equivalent to 0

So if your object is called, myObject...

var c = 0;
for(c in myObject) {
    console.log(Object.keys(myObject[c]));
}

Walla! This will definitely work in the latest firefox and ie11 and chrome...

Here is some documentation at MDN https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys

It depends on the application and the purpose. When high availability and performance is not critical, it's not bad to not to separate the DB and web server. Especially considering the performance gains - if the appliation makes a large amount of database queries, a considerable amount of network load can be removed by keeping it all on the same system, keeping the response times low.

If it is just "access in other controller" then you can use angular constants for that, the benefit is; you can add some global settings or other things that you want to access throughout application

app.constant(‘appGlobals’, {
    defaultTemplatePath: '/assets/html/template/',
    appName: 'My Awesome App'
});

and then access it like:

app.controller(‘SomeController’, [‘appGlobals’, function SomeController(config) {
    console.log(appGlobals);
    console.log(‘default path’, appGlobals.defaultTemplatePath);
}]);

(didn't test)

On most of UNIX based sys, its at /usr/bin/git (if installed with default options)
all git related scripts are at /usr/libexec/git-core

Looks like most of the answers on this thread have not kept up. iOS Safari on iPads have fullscreen support now and it's very easy to implement using javascript.

Here's my full article on how to implement fullscreen capability on your web app.

Two suggestions:

• Use a HashSet instead of an ArrayList. This will speed up the contains() checks considerably if you have a long list

• Make sure Customer.equals() and Customer.hashCode() are implemented properly, i.e. they should be based on the combined values of the underlying fields in the customer object.

There is no preferred method - everything depends on your needs. Often you need to have different Python interpreters on the system for whatever reason. In this case you need to install the stuff individually for each interpreter. Apart from that: I prefer installing stuff myself instead of depending of pre-packaged stuff sometimes causing issues - but that's only one possible opionion.

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

DIV does not fire a resize event, so you won't be able to do exactly what you've coded, but you could look into monitoring DOM properties.

If you are actually working with something like resizables, and that is the only way for a div to change in size, then your resize plugin will probably be implementing a callback of its own.

perhaps this comes too late, but still it could be nice to "document it" for others out there.

I received the same error after experimenting and testing with Remote Desktop Services on a MS Server 2012 with MS SQL Server 2012.

During the Remote Desktop Services install one is asked to create a (local) certificate, and so I did. After finishing the test/experiments I removed the Remote Desktop Services. That's when this error appeared (I cannot say whether the error occured during the test with RDS, I don't remember if I used/tried the SQL Connection during the RDS test).

I am not sure how to solve this since the default certificate does not work for me, but the "RDS" certificate does.

BTW, the certificates are found in App: "SQL Server Configuration Manager" -> "SQL Server Network Configuration" -> Right click: "Protocols for " -> Select "Properties" -> Tab "Certificate"

My default SQL Certificate is named: ConfigMgr SQL Server Identification Certificate, has expiration date: 2114-06-09.

Hope this can give a hint to others.

The fastest way, to get a hash string for password store purposes, is a following code:

    internal static string GetStringSha256Hash(string text)
    {
        if (String.IsNullOrEmpty(text))
            return String.Empty;

        using (var sha = new System.Security.Cryptography.SHA256Managed())
        {
            byte[] textData = System.Text.Encoding.UTF8.GetBytes(text);
            byte[] hash = sha.ComputeHash(textData);
            return BitConverter.ToString(hash).Replace("-", String.Empty);
        }
    }

Remarks:

• if the method is invoked often, the creation of sha variable should be refactored into a class field;
• output is presented as encoded hex string;

Yes you can do that.

Here is an example:

a{
    background:IMAGE-URL;
    display:block;
    height:IMAGE-HEIGHT;
    width:IMAGE-WIDTH;
}

Of course you can modify the above example to your need. The important thing is to make it appear as a block (display:block) or an inline block (display:inline-block).

To get the output of ls, use stdout=subprocess.PIPE.

>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo

The command cdrecord --help outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.

>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.

subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

As mentioned by Chris Morgan, you should be using proc.communicate() instead of proc.read().

>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout: 
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

In my case I was trying to 'get' from express app. Instead I had to do SET.

app.set('view engine','pug');

We can use paste0:

df$combField <- paste0(df$x, df$y)

If you do not want any padding space introduced in the concatenated field. This is more useful if you are planning to use the combined field as a unique id that represents combinations of two fields.

1. Check the trees.config file which located in config folder... sometimes (I don't know why) this file became to be empty like someone delete the content inside... keep backup up of this file in your local pc then when this error appear - replace the server file with your local file. This is what i do when this error happened.

2. check the available space on the server. sometimes this is the problem.

Good luck.

This answer attempts a pragmatic summary of the many great answers on this page:

^{jeb's great answer deserves special mention, because it really goes in-depth and covers many edge cases.
Notably, he points out that a misconstructed variable/parameter reference such as %~ can break any of the solutions below - including REM lines.}

Whole-line comments - the only directly supported style:

• REM (or case variations thereof) is the only official comment construct, and is the safest choice - see Joey's helpful answer.

• :: is a (widely used) hack, which has pros and cons:

  • Pros:

    • Visual distinctiveness and, possibly, ease of typing.
    • Speed, although that will probably rarely matter - see jeb's great answer and Rob van der Woude's excellent blog post.

  • Cons:

    • Inside (...) blocks, :: can break the command, and the rules for safe use are restrictive and not easy to remember - see below.

If you do want to use ::, you have these choices:

• Either: To be safe, make an exception inside (...) blocks and use REM there, or do not place comments inside (...) altogether.
• Or: Memorize the painfully restrictive rules for safe use of :: inside (...), which are summarized in the following snippet:

@echo off

for %%i in ("dummy loop") do (

  :: This works: ONE comment line only, followed by a DIFFERENT, NONBLANK line.
  date /t

  REM If you followed a :: line directly with another one, the *2nd* one
  REM would generate a spurious "The system cannot find the drive specified."
  REM error message and potentially execute commands inside the comment.
  REM In the following - commented-out - example, file "out.txt" would be
  REM created (as an empty file), and the ECHO command would execute.
  REM   :: 1st line
  REM   :: 2nd line > out.txt & echo HERE

  REM NOTE: If :: were used in the 2 cases explained below, the FOR statement
  REM would *break altogether*, reporting:
  REM  1st case: "The syntax of the command is incorrect."
  REM  2nd case: ") was unexpected at this time."

  REM Because the next line is *blank*, :: would NOT work here.

  REM Because this is the *last line* in the block, :: would NOT work here.
)

Emulation of other comment styles - inline and multi-line:

Note that none of these styles are directly supported by the batch language, but can be emulated.

Inline comments:

<sup>* The code snippets below use ver as a stand-in for an arbitrary command, so as to facilitate experimentation.
* To make SET commands work correctly with inline comments, double-quote the name=value part; e.g., SET "foo=bar".[1]</sup>

In this context we can distinguish two subtypes:

• EOL comments ([to-the-]end-of-line), which can be placed after a command, and invariably extend to the end of the line (again, courtesy of jeb's answer):

  • ver & REM <comment> takes advantage of the fact that REM is a valid command and & can be used to place an additional command after an existing one.
  • ver & :: <comment> works too, but is really only usable outside of (...) blocks, because its safe use there is even more limited than using :: standalone.

• Intra-line comments, which be placed between multiple commands on a line or ideally even inside of a given command.
  Intra-line comments are the most flexible (single-line) form and can by definition also be used as EOL comments.

  • ver & REM^. ^<comment^> & ver allows inserting a comment between commands (again, courtesy of jeb's answer), but note how < and > needed to be ^-escaped, because the following chars. cannot be used as-is: < > | (whereas unescaped & or && or || start the next command).

  • %= <comment> =%, as detailed in dbenham's great answer, is the most flexible form, because it can be placed inside a command (among the arguments).
    It takes advantage of variable-expansion syntax in a way that ensures that the expression always expands to the empty string - as long as the comment text contains neither % nor :
    Like REM, %= <comment> =% works well both outside and inside (...) blocks, but it is more visually distinctive; the only down-sides are that it is harder to type, easier to get wrong syntactically, and not widely known, which can hinder understanding of source code that uses the technique.

Multi-line (whole-line block) comments:

• James K's answer shows how to use a goto statement and a label to delimit a multi-line comment of arbitrary length and content (which in his case he uses to store usage information).

• Zee's answer shows how to use a "null label" to create a multi-line comment, although care must be taken to terminate all interior lines with ^.

• Rob van der Woude's blog post mentions another somewhat obscure option that allows you to end a file with an arbitrary number of comment lines: An opening ( only causes everything that comes after to be ignored, as long as it doesn't contain a ( non-^-escaped) ), i.e., as long as the block is not closed.

^{[1] Using SET "foo=bar" to define variables - i.e., putting double quotes around the name and = and the value combined - is necessary in commands such as SET "foo=bar" & REM Set foo to bar., so as to ensure that what follows the intended variable value (up to the next command, in this case a single space) doesn't accidentally become part of it.
(As an aside: SET foo="bar" would not only not avoid the problem, it would make the double quotes part of the value).
Note that this problem is inherent to SET and even applies to accidental trailing whitespace following the value, so it is advisable to always use the SET "foo=bar" approach.}

Using the Gnumeric spreadsheet application which comes which a commandline utility called ssconvert is indeed super simple:

find . -name '*.xlsx' -exec ssconvert -T Gnumeric_stf:stf_csv {} \;

and you're done!

Each RUN instruction in a Dockerfile is executed in a different layer (as explained in the documentation of RUN).

In your Dockerfile, you have three RUN instructions. The problem is that MySQL server is only started in the first. In the others, no MySQL are running, that is why you get your connection error with mysql client.

To solve this problem you have 2 solutions.

Solution 1: use a one-line RUN

RUN /bin/bash -c "/usr/bin/mysqld_safe --skip-grant-tables &" && \
  sleep 5 && \
  mysql -u root -e "CREATE DATABASE mydb" && \
  mysql -u root mydb < /tmp/dump.sql

Solution 2: use a script

Create an executable script init_db.sh:

#!/bin/bash
/usr/bin/mysqld_safe --skip-grant-tables &
sleep 5
mysql -u root -e "CREATE DATABASE mydb"
mysql -u root mydb < /tmp/dump.sql

Add these lines to your Dockerfile:

ADD init_db.sh /tmp/init_db.sh
RUN /tmp/init_db.sh

The problem here was a typo error in the password used, which was not easily identified due to the characters / letters used in the password.

For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str to int) so you must do this yourself. You'll like that in the long-run, trust me!

Maybe faster than @ellockie ( Maybe )

Test results in screenshot below:

If you use Maven, you can use xvfb-maven-plugin to start xvfb before tests, run them using related DISPLAY environment variable, and stop xvfb after all.

output = new ByteArrayOutputStream();
...
input = new ByteArrayInputStream( output.toByteArray() )

Multiple clients can connect to the same port (say 80) on the server because on the server side, after creating a socket and binding (setting local IP and port) listen is called on the socket which tells the OS to accept incoming connections.

When a client tries to connect to server on port 80, the accept call is invoked on the server socket. This creates a new socket for the client trying to connect and similarly new sockets will be created for subsequent clients using same port 80.

Words in italics are system calls.

Here is an example of what Wilco suggested:

$cmd = 'nohup nice -n 10 /usr/bin/php -c /path/to/php.ini -f /path/to/php/file.php action=generate var1_id=23 var2_id=35 gen_id=535 > /path/to/log/file.log & echo $!';
$pid = shell_exec($cmd);

Basically this executes the PHP script at the command line, but immediately returns the PID and then runs in the background. (The echo $! ensures nothing else is returned other than the PID.) This allows your PHP script to continue or quit if you want. When I have used this, I have redirected the user to another page, where every 5 to 60 seconds an AJAX call is made to check if the report is still running. (I have a table to store the gen_id and the user it's related to.) The check script runs the following:

exec('ps ' . $pid , $processState);
if (count($processState) < 2) {
     // less than 2 rows in the ps, therefore report is complete
}

There is a short post on this technique here: http://nsaunders.wordpress.com/2007/01/12/running-a-background-process-in-php/

Here is the step by step process to include php code in html file ( Tested )

If PHP is working there is only one step left to use PHP scripts in files with *.html or *.htm extensions as well. The magic word is ".htaccess". Please see the Wikipedia definition of .htaccess to learn more about it. According to Wikipedia it is "a directory-level configuration file that allows for decentralized management of web server configuration."

You can probably use such a .htaccess configuration file for your purpose. In our case you want the webserver to parse HTML files like PHP files.

First, create a blank text file and name it ".htaccess". You might ask yourself why the file name starts with a dot. On Unix-like systems this means it is a dot-file is a hidden file. (Note: If your operating system does not allow file names starting with a dot just name the file "xyz.htaccess" temporarily. As soon as you have uploaded it to your webserver in a later step you can rename the file online to ".htaccess") Next, open the file with a simple text editor like the "Editor" in MS Windows. Paste the following line into the file: AddType application/x-httpd-php .html .htm If this does not work, please remove the line above from your file and paste this alternative line into it, for PHP5: AddType application/x-httpd-php5 .html .htm Now upload the .htaccess file to the root directory of your webserver. Make sure that the name of the file is ".htaccess". Your webserver should now parse *.htm and *.html files like PHP files.

You can try if it works by creating a HTML-File like the following. Name it "php-in-html-test.htm", paste the following code into it and upload it to the root directory of your webserver:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
     <HTML>
 <HEAD>
 <TITLE>Use PHP in HTML files</TITLE>
 </HEAD>

   <BODY>
    <h1>
    <?php echo "It works!"; ?>
    </h1>
  </BODY>
 </HTML>

Try to open the file in your browser by typing in: http://www.your-domain.com/php-in-html-test.htm (once again, please replace your-domain.com by your own domain...) If your browser shows the phrase "It works!" everything works fine and you can use PHP in .*html and *.htm files from now on. However, if not, please try to use the alternative line in the .htaccess file as we showed above. If is still does not work please contact your hosting provider.

Just click on the certificate in the keychain access and change the access permission if you want to avoid entering password at all, else select Always allow and it will prompt probably 4-5 times and it will be done.

Use this

os.chdir('C:/Users\expoperialed\Desktop\Python')

It depends on what you are developing.

A content-oriented website will have its content changing frequently and a Website is better for that.

An application tends to have its data stored in a database and its pages and code change rarely. In this case it's better to have a Web application where deployment of assemblies is much more controlled and has better support for unit testing.

You need to add annotations to the Junit class, telling it to use the SpringJunitRunner. The ones you want are:

@ContextConfiguration("/test-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)

This tells Junit to use the test-context.xml file in same directory as your test. This file should be similar to the real context.xml you're using for spring, but pointing to test resources, naturally.

I think I got it. I have to use org.w3c.dom.Element explicitly. I had a different Element field too.

The .load("file.txt") is much easier. Which works but even if testing, you won't get results from a localdrive, you'll need an actual http server. The invisible error is an XMLHttpRequest error.

To center a block object (e.g. the ul) you need to set a width on it and then you can set that objects left and right margins to auto.

To center the inline content of block object (e.g. the inline content of li) you can set the css property text-align: center;.

YES YOU CAN do it!! It's a little tricky way ; ) (it almost works on ios)

var iframe = document.createElement("IFRAME");
iframe.setAttribute("src", 'data:text/plain,');
document.documentElement.appendChild(iframe);
if(window.frames[0].window.confirm("Are you sure?")){
    // what to do if answer "YES"
}else{
    // what to do if answer "NO"
}

Enjoy it!

It works for me.

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

Generic methods to compare a char at a position between 2 strings with ignore case.

public static boolean isEqualIngoreCase(char one, char two){
    return Character.toLowerCase(one)==Character .toLowerCase(two);
}

public static boolean isEqualStringCharIgnoreCase(String one, String two, int position){
    char oneChar = one.charAt(position);
    char twoChar = two.charAt(position);
    return isEqualIngoreCase(oneChar, twoChar);
}

Function call

boolean isFirstCharEqual = isEqualStringCharIgnoreCase("abc", "ABC", 0)

One difference - apart from the possibility to use wildcards with LIKE - is in trailing spaces: The = operator ignores trailing space, but LIKE does not.

I was using above command but it was not working. This command worked for me:

python -m pip uninstall pip setuptools

with open(filename) as f:
  while True:
    c = f.read(1)
    if not c:
      print "End of file"
      break
    print "Read a character:", c

I would use a StringBuilder class for doing string manipulation as it will more efficient (being mutable)

string flights = "Flight A, B,C,D";
StringBuilder message = new StringBuilder();
message.Append("Hi We have these flights for you: ");
message.Append(flights);
message.Append(" . Which one do you want?");

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

I realize this is a bit late, but I've had success with annotating a timestamp column with

@Column(name="timestamp", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")

This should also work with CURRENT_DATE and CURRENT_TIME. I'm using JPA/Hibernate with Oracle, so YMMV.

I hope this will help you

Create table :

create table users (id int,first_name varchar(10),last_name varchar(10));

Insert values into the table :

insert into users (id,first_name,last_name) values(1,'Abhishek','Anand');

you have to split the datetime and then store it with your desired format like dd/MM/yyyy. then you can use this query with between but i have objection using this becasue it will search every single data on your database,so i suggest you can use datediff.

        Dim start = txtstartdate.Text.Trim()
        Dim endday = txtenddate.Text.Trim()
        Dim arr()
        arr = Split(start, "/")
        Dim dt As New DateTime
        dt = New Date(Val(arr(2).ToString), Val(arr(1).ToString), Val(arr(0).ToString))
        Dim arry()
        arry = Split(endday, "/")
        Dim dt2 As New DateTime
        dt2 = New Date(Val(arry(2).ToString), Val(arry(1).ToString), Val(arry(0).ToString))

        qry = "SELECT * FROM [calender] WHERE datediff(day,'" & dt & "',[date])>=0 and datediff(day,'" & dt2 & "',[date])<=0 "

here i have used dd/MM/yyyy format.

vector_avg <- function(x){
  sum_x = 0
  for(i in 1:length(x)){
    if(!is.na(x[i]))
      sum_x = sum_x + x[i]
  }
  return(sum_x/length(x))
}

I had the same problem and I had solved it with:

1.Right click to solution and click 'Clean Solution'

2.Click 'References' folder in solution explorer and select the problem reference (in your case it seems System.Web.Mvc) and then right click and click 'Properties'.

3.In the properties window, make sure that the 'Copy Local' property is set to 'True'

This worked for me. Hope it works for someone else

Helpful Note: As it has mentioned in comments by @Vlad:

If it is already set to True:

1. Set it False
2. Set it True again
3. Rebuild

You need to pass your data in the request body as a raw string rather than FormUrlEncodedContent. One way to do so is to serialize it into a JSON string:

var json = JsonConvert.SerializeObject(data); // or JsonSerializer.Serialize if using System.Text.Json

Now all you need to do is pass the string to the post method.

var stringContent = new StringContent(json, UnicodeEncoding.UTF8, "application/json"); // use MediaTypeNames.Application.Json in Core 3.0+ and Standard 2.1+

var client = new HttpClient();
var response = await client.PostAsync(uri, stringContent);

I had this problem in Microsoft Visual Studio 2008 and the solution is easy. when you run your project please set in "Debug" mode not "Release". The another people solution can be useful.

See this TechNet article: Runas command documentation

I had some data I had to get from mssql into mysql, had difficulty finding a solution. So what I did in the end (a bit of a long winded way to do it, but as a last resort it works) was:

• Open the mssql database in sql server management studio express (I used 2005)
• Open each table in turn and

• Click the top left corner box to select whole table:

• Copy data to clipboard (ctrl + v)

• Open ms excel
• Paste data from clipboard
• Save excel file as .csv
• Repeat the above for each table
• You should now be able to import the data into mysql

Hope this helps

I had a similar issue. Using chrome://net-internals/#events I was able to see that my issue was due to some silent redirect. My get request was being fired in an onload script. The url was of the form, "http://example.com/inner-path" and the 301 was permanently redirecting to "/inner-path". To fix the issue I just changed the url to "/inner-path" and that fixed the issue. I still don't know why a script that worked a week ago was suddenly giving me issue... Hope this helps someone

If I had to guess, I'd say you installed the PPA 7.1.8 as CLI only (php7-cli). You're getting your version info from that, but your libapache2-mod-php package is still 14.04 main which is 5.6. Check your phpinfo in your browser to confirm the version. You might also consider migrating to Ubuntu 16.04 to get PHP 7.0 in main.

It looks like your syntax is slightly out. This has some good examples

DECLARE @TempCustomer TABLE
(
   CustomerId uniqueidentifier,
   FirstName nvarchar(100),
   LastName nvarchar(100),
   Email nvarchar(100)
);
INSERT @TempCustomer 
SELECT 
    CustomerId, 
    FirstName, 
    LastName, 
    Email 
FROM 
    Customer
WHERE 
    CustomerId = @CustomerId

Then later

SELECT CustomerId FROM @TempCustomer

hey I understand this is an old thread but I have a query in regards to apachebenchmarking. how do you collect the metrics from apache benchmarking. P.S: I have to do it via telegraf and put it to influxdb . any suggestions/advice/help would be appreciated. Thanks a ton.

There is an easy way to get Jobs' Owners info from multiple instances by PowerShell:

Run the script in your PowerShell ISE:

Loads SQL Powerhell SMO and commands:

Import-Module SQLPS -disablenamechecking

BUild list of Servers manually (this builds an array list):

$SQLServers = "SERVERNAME\INSTANCE01","SERVERNAME\INSTANCE02","SERVERNAME\INSTANCE03";
$SysAdmins = $null;
foreach($SQLSvr in $SQLServers)
{
    ## - Add Code block:
    $MySQL = new-object Microsoft.SqlServer.Management.Smo.Server $SQLSvr;
    DIR SQLSERVER:\SQL\$SQLSvr\JobServer\Jobs| FT $SQLSvr, NAME, OWNERLOGINNAME -Auto 
    ## - End of Code block
}

Try this:

 driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

I had a similar problem after first pulling and starting a new solution. It was fixed in visual studio by first cleaning the project. Then restoring the packages. When I built again, there were no more type or namespace errors.

GPS is generally more accurate than network but sometimes GPS is not available, therefore you might need to switch between the two.

A good start might be to look at the android dev site. They had a section dedicated to determining user location and it has all the code samples you need.

If you tried sudo apt-get remove docker-compose and get E: Unable to locate package docker-compose, try this method :

This command must return a result, in order to check it is installed here :

ls -l /usr/local/bin/docker-compose

Remove the old version :

sudo rm -rf docker-compose

Download the last version (check official repo : docker/compose/releases) :

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

(replace 1.24.0 if needed)

Finally, apply executable permissions to the binary:

sudo chmod +x /usr/local/bin/docker-compose

Check version :

docker-compose -v

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.

Another possibility:

1. Create a UIButton in Interface builder.
2. Give it a type 'Custom'
3. Now, in IB it is possible to change the background color

However, the button is square, and that is not what we want. Create an IBOutlet with a reference to this button and add the following to the viewDidLoad method:

[buttonOutlet.layer setCornerRadius:7.0f];
[buttonOutlet.layer setClipToBounds:YES];

Don't forget to import QuartzCore.h

"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() +"'";

this is what i did!!

I had a similar problem with HTML input fields in MVC. The web paged only showed the first keyword of the field. Example: input field: "The quick brown fox" Displayed value: "The"

The resolution was to put the variable in quotes in the value statement as follows:

<input class="ParmInput" type="text" id="respondingRangerUnit" name="respondingRangerUnit"
       onchange="validateInteger(this.value)" value="@ViewBag.respondingRangerUnit">

Take a look at the System log in Windows EventViewer (eventvwr from the command line).
You should see entries with source as 'Service Control Manager'. e.g. on my WinXP machine,

Event Type: Information
Event Source:   Service Control Manager
Event Category: None
Event ID:   7036
Date:       7/1/2009
Time:       12:09:43 PM
User:       N/A
Computer:   MyMachine
Description:
The Background Intelligent Transfer Service service entered the running state.

According to @Shovalt's answer, but in short:

Alternatively you could use the following lines of code

    from sklearn.metrics import f1_score
    metrics.f1_score(y_test, y_pred, labels=np.unique(y_pred))

This should remove your warning and give you the result you wanted, because it no longer considers the difference between the sets, by using the unique mode.

This really depends on your requirements. First, see if you really need a workflow engine (this or other sources). Unless you really need it, probably you should avoid it.

If you really need what provides a workflow engine, I would pick one that is already built. People who works with jbpm or activiti have much more experience than you in building workflow engines, so it is probably already tunned to improve performance.

FormsAuthentication.Decrypt takes the actual value of the cookie, not the name of it. You can get the cookie value like

HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName].Value;

and decrypt that.

According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:

• Informing each search engine of the location through their provided interface
• Adding url to the robots.txt file
• Submiting url to search engines through http

So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.

using jQuery it's easy...

 $('YOUR CLASS SELECTOR').click(function(){

            $(this).toggle();
});

TreeViewItem tempItem = new TreeViewItem();
TreeViewItem tempItem1 = new TreeViewItem(); 
tempItem =  (TreeViewItem) treeView1.Items.GetItemAt(0);    // Selecting the first of the top level nodes
tempItem1 = (TreeViewItem)tempItem.Items.GetItemAt(0);      // Selecting the first child of the first first level node
SelectedCategoryHeaderString = tempItem.Header.ToString();  // gets the header for the first top level node
SelectedCategoryHeaderString = tempItem1.Header.ToString(); // gets the header for the first child node of the first top level node
tempItem.IsExpanded = true;         //  will expand the first node

You can also do git log | grep commit | wc -l

and get the result back

Yes, a struct is identical to a class except for the default access level (member-wise and inheritance-wise). (and the extra meaning class carries when used with a template)

Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.

struct foo {
  int bar;
  foo() : bar(3) {}   //look, a constructor
  int getBar() 
  { 
    return bar; 
  }
};

foo f;
int y = f.getBar(); // y is 3

Remember that after installing Imagick (or indeed any PHP module) you need to restart your web server and/or php-fpm if you're using it, for the module to appear in phpinfo().

Change the definition of multiply to take additional unknown arguments:

multiply <- function(a, b, ...) {
  # Original code
}

This is the simplest solution

    static void title(String a,String b){
    String ra = Character.toString(Character.toUpperCase(a.charAt(0)));
    String rb = Character.toString(Character.toUpperCase(b.charAt(0)));
    for(int i=1;i<a.length();i++){
        ra+=a.charAt(i);
    }
    for(int i=1;i<b.length();i++){
        rb+=b.charAt(i);
    }
    System.out.println(ra+" "+rb);

Yeah first method will work on any element called from elsewhere since it will always take the target element irrespective of id.

Views can be a godsend when when doing reporting on legacy databases. In particular, you can use sensical table names instead of cryptic 5 letter names (where 2 of those are a common prefix!), or column names full of abbreviations that I'm sure made sense at the time.

Just have a line added to your crontab..

Make sure the file is executable:

chmod +x /path_to_you_file/your_file

To edit crontab file:

crontab -e

Line you have to add:

@reboot  /path_to_you_file/your_file

That simple!

Your format string is wrong. Change it to

insert = DateTime.ParseExact(line[i], "M/d/yyyy hh:mm", CultureInfo.InvariantCulture);

Basically, the module cannot be instantiated. When a class includes a module, a proxy superclass is generated that provides access to all the module methods as well as the class methods.

A module can be included by multiple classes. Modules cannot be inherited, but this "mixin" model provides a useful type of "multiple inheritrance". OO purists will disagree with that statement, but don't let purity get in the way of getting the job done.

You need to make your regular expression non-greedy, because by default, "(.*)" will match all of "file path/level1/level2" xxx some="xxx".

Instead you can make your dot-star non-greedy, which will make it match as few characters as possible:

/location="(.*?)"/

Adding a ? on a quantifier (?, * or +) makes it non-greedy.

You can simple put the default value using default(). See the example

 $table->enum('is_approved', array('0','1'))->default('0');

I have used enum here and the default value is 0.

Of course you can use the StringTokenizer class to split the String with '.' or '/', and check if the last word is "work".

Intrinsic Content Size of Multi-Line Text

The intrinsic content size of UILabel and NSTextField is ambiguous for multi-line text. The height of the text depends on the width of the lines, which is yet to be determined when solving the constraints. In order to solve this problem, both classes have a new property called preferredMaxLayoutWidth, which specifies the maximum line width for calculating the intrinsic content size.

Since we usually don’t know this value in advance, we need to take a two-step approach to get this right. First we let Auto Layout do its work, and then we use the resulting frame in the layout pass to update the preferred maximum width and trigger layout again.

- (void)layoutSubviews
{
    [super layoutSubviews];
    myLabel.preferredMaxLayoutWidth = myLabel.frame.size.width;
    [super layoutSubviews];
}

The first call to [super layoutSubviews] is necessary for the label to get its frame set, while the second call is necessary to update the layout after the change. If we omit the second call we get a NSInternalInconsistencyException error, because we’ve made changes in the layout pass which require updating the constraints, but we didn’t trigger layout again.

We can also do this in a label subclass itself:

@implementation MyLabel
- (void)layoutSubviews
{
    self.preferredMaxLayoutWidth = self.frame.size.width;
    [super layoutSubviews];
}
@end

In this case, we don’t need to call [super layoutSubviews] first, because when layoutSubviews gets called, we already have a frame on the label itself.

To make this adjustment from the view controller level, we hook into viewDidLayoutSubviews. At this point the frames of the first Auto Layout pass are already set and we can use them to set the preferred maximum width.

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    myLabel.preferredMaxLayoutWidth = myLabel.frame.size.width;
    [self.view layoutIfNeeded];
}

Lastly, make sure that you don’t have an explicit height constraint on the label that has a higher priority than the label’s content compression resistance priority. Otherwise it will trump the calculated height of the content. Make sure to check all the constraints that can affect label's height.

Change the .find to .filter...

I came across this post as I had the same issue then I thought why mess about with css, adjusting values and hitting refresh when you can easily adjust the opacity in Photoshop? Copy the image, paste it as a new layer then move the opacity slider.

If your code is supposed to run in different environments, I would consider using the Environment.NewLine constant, since it is specifically the newline used in the specific environment.

line = line.Replace(Environment.NewLine, "newLineReplacement");

However, if you get the text from a file originating on another system, this might not be the correct answer, and you should replace with whatever newline constant is used on the other system. It will typically be \n or \r\n.

For example summer :

lblSummer.foreColor = color.Yellow;

Actually you can fix it with following steps -

1. Do cls.__dict__
2. This will give you dictionary format output which will contain {'isFilled':True} or {'isFilled':False} depending upon what you have set.
3. Delete this entry - del cls.__dict__['isFilled']
4. You will be able to call the method now.

In this case, we delete the entry which overrides the method as mentioned by BrenBarn.

None of the answers include the overhead size and the metadata sizes of tables.

Here is a more accurate estimation of the "disk space" allocated by a database.

SELECT ROUND((SUM(data_length+index_length+data_free) + (COUNT(*) * 300 * 1024))/1048576+150, 2) AS MegaBytes FROM information_schema.TABLES WHERE table_schema = 'DATABASE-NAME'

Yet Another Snippet

Referred main as the main function and exit_gracefully as the CTRL + c handler

if __name__ == '__main__':
    try:
        main()
    except KeyboardInterrupt:
        pass
    finally:
        exit_gracefully()

Examples

Get encoding of all files in current directory:

encoding-checker

Return encoding of all md files in current directory:

encoding-checker -p "*.md"

Get encoding of all files in current directory and its subfolders (will take quite some time for huge folders; seemingly unresponsive):

encoding-checker -p "**"

For more examples refer to the npm docu or the official repository.

Static variables are not good nor evil. They represent attributes that describe the whole class and not a particular instance. If you need to have a counter for all the instances of a certain class, a static variable would be the right place to hold the value.

Problems appear when you try to use static variables for holding instance related values.

Well you can simply use Math.pow(a,b) as you have used earlier and just convert its value by using (int) before it. Below could be used as an example to it.

int x = (int) Math.pow(a,b);

where a and b could be double or int values as you want. This will simply convert its output to an integer value as you required.

Brackets Matching program without using stack

        Scanner scan=new Scanner(System.in);
        System.out.print("Input : " );
        String s = scan.nextLine();
        scan.close();
        System.out.println("\n...working...\n");
        String o="([{";
        String c=")]}";
        String x=" ";
        int check =0;
        for (int i = 0; i < s.length(); i++) {
            if(o.contains(String.valueOf(s.charAt(i)))){
                x+=s.charAt(i);     
                 //System.out.println("In : "+x); // stack in
            }else if(c.contains(String.valueOf(s.charAt(i)))) { 
                char temp = s.charAt(i);
                if(temp==')') temp = '(';
                if(temp=='}') temp = '{';
                if(temp==']') temp = '[';
                if(x.charAt(x.length()-1)==temp) {
                    x=" "+x.substring(1,x.length()-1);
                    //System.out.println("Out : "+x);   // stack out
            }else {

Also, when you uninstall the package, the first item listed is the directory to the executable.

You can use "break" to break the loop, which will not allow the loop to process more conditions

You can use retus to make cross-platform synchronous HTTP requests:

const retus = require("retus");

const { body } = retus("https://google.com");
//=> "<!doctype html>..."

That's it!

Most of the solutions are working but why take so efforts while we also can get mime type very easily. In System.Web assembly, there is method for getting the mime type from file name. eg:

string mimeType = MimeMapping.GetMimeMapping(filename);

You cannot create a primary key on a view. In SQL Server you can create an index on a view but that is different to creating a primary key.

If you give us more information as to why you want a key on your view, perhaps we can help with that.

I've been playing around a little bit and came up with a simplified, more generic solution:

private static string sendHttpRequest(string url, NameValueCollection values, NameValueCollection files = null)
{
    string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");
    // The first boundary
    byte[] boundaryBytes = System.Text.Encoding.UTF8.GetBytes("\r\n--" + boundary + "\r\n");
    // The last boundary
    byte[] trailer = System.Text.Encoding.UTF8.GetBytes("\r\n--" + boundary + "--\r\n");
    // The first time it itereates, we need to make sure it doesn't put too many new paragraphs down or it completely messes up poor webbrick
    byte[] boundaryBytesF = System.Text.Encoding.ASCII.GetBytes("--" + boundary + "\r\n");

    // Create the request and set parameters
    HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
    request.ContentType = "multipart/form-data; boundary=" + boundary;

You can use it like this:

string fileLocation = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + Path.DirectorySeparatorChar + "somefile.jpg";
NameValueCollection values = new NameValueCollection();
NameValueCollection files = new NameValueCollection();
values.Add("firstName", "Alan");
files.Add("profilePicture", fileLocation);
sendHttpRequest("http://example.com/handler.php", values, files);

And in the PHP script you could handle data like this:

echo $_POST['firstName'];
$name = $_POST['firstName'];
$image = $_FILES['profilePicture'];
$ds = DIRECTORY_SEPARATOR;
move_uploaded_file($image['tmp_name'], realpath(dirname(__FILE__)) . $ds . "uploads" . $ds . $image['name']);

Put all the divs in a individual table cells and set the table style to padding: 5px;.

E.g.

<table style="width: 100%; padding: 5px;">_x000D_
<tbody>_x000D_
<tr>_x000D_
<td>_x000D_
<div style="background-color: red;">A</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: orange;">B</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: green;">C</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: blue;">D</div>_x000D_
</td>_x000D_
</tr>_x000D_
</tbody>_x000D_
</table>

I've seen this many times over the last decade and just had it again. There are many problems that result in the same error.

One cause is a renaming of files. If you're working with .cshtml files, check all namespaces within those files and within the Views\web.config file. For web forms, rename Default.aspx (related .cs and designer files are automatically renamed). The codebehind changes but the Inherits line in the markup doesn't. Change it manually. Double check the designer page. Sometimes (VS2005-8?) the designer page doesn't reflect a change in the namespace. Haven't seen this in 2010+.

Another issue is when it all works in VS or on your local PC but not when you deploy. This could be because the deployment environment isn't structured the same. For example, the error occurs if you place your code in a virtual directory under an application folder, but it doesn't occur if you create a new application folder and place all of your files in there. I don't understand this one, as I've had the new child/virtual folder set with the same permissions (or so I think) and (I believe) the application pool should work the same for everything in a given application folder.

In my case I've also had a bin folder with assemblies that are updated from other assemblies on the IIS server. Again, ensuring that these are run in a separate application folder resulted in success.

HTH

I think this is the easiest way to loop in react js

<ul>
    {yourarray.map((item)=><li>{item}</li>)}
</ul>

You can try using parentheses around the OR expressions to make sure your query is interpreted correctly, or more concisely, use IN:

SELECT ads.*, location.county 
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1 
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)

Using a loop -

public static boolean containsDigit(final String aString)
{
    if (aString != null && !aString.isEmpty())
    {
        for (char c : aString.toCharArray())
        {
            if (Character.isDigit(c))
            {
                return true;
            }
        }
    }

    return false;
}

Using a stream -

public static boolean containsDigit(final String aString)
{
    return aString != null && !aString.isEmpty() &&
            aString.chars().anyMatch(Character::isDigit);
}

Try

console.log(_x000D_
  new Date().toLocaleString().slice(9, -3)_x000D_
  , new Date().toString().slice(16, -15)_x000D_
);

Extending Dale Ragan's answer, his example for reuse, create an ApplicationController class which derives from Controller, and in turn have all your other controllers derive from that ApplicationController class rather than Controller.

Example:

public class MyCustomApplicationController : Controller {}

public class HomeController : MyCustomApplicationController {}

On your new ApplicationController create a property named ExecutingAction with this signature:

protected ActionDescriptor ExecutingAction { get; set; }

And then in the OnActionExecuting method (from Dale Ragan's answer), simply assign the ActionDescriptor to this property and you can access it whenever you need it in any of your controllers.

string currentActionName = this.ExecutingAction.ActionName;

Another way, which I've been using for awhile in XCode3:

See steps 1-15 above.

1. Choose /bin/bash as your executable
2. For the "Debugger" field, select "None".
3. In the "Arguments" tab, click the "Base Expansions On" field and select the target you created earlier.
4. Click the "+" icon under "Arguments Passed On Launch". You may have to expand that section by clicking on the triangle pointing to the right.
5. Type in "-l". This will tell bash to use your login environment (PYTHONPATH, etc..)
6. Do step #19 again.
7. Type in "-c '$(SOURCE_ROOT)/.py'"
8. Click "OK".
9. Start coding.

The nice thing about this way is it will use the same environment to develop in that you would use to run in outside of XCode (as setup from your bash .profile).

It's also generic enough to let you develop/run any type of file, not just python.

Quite an old question, but might be helpful to somebody in need.

If you know the url, 1. open the chrome browser, 2. open developer tools in chrome , 3. Put the url in search bar and hit enter 4. look in network tab, you will see the ip and port both

ternary operator ? : is just short form of if/else

case "$b" in
 5) a=$c ;;
 *) a=$d ;;
esac

Or

 [[ $b = 5 ]] && a="$c" || a="$d"

To run your_command as a subprocess in a different directory, pass cwd parameter, as suggested in @wim's answer:

import subprocess

subprocess.check_call(['your_command', 'arg 1', 'arg 2'], cwd=working_dir)

A child process can't change its parent's working directory (normally). Running cd .. in a child shell process using subprocess won't change your parent Python script's working directory i.e., the code example in @glglgl's answer is wrong. cd is a shell builtin (not a separate executable), it can change the directory only in the same process.

Go to Build Settings, under Code Signing, set Code Signing Identity as iOS Developer & Provisioning Profile as Automatic.

Select your device (now visible) from drop down list and run your app.

I tried the ng-cloak solution above but it still has intermittent issues with Firefox. The only workaround that worked for me is to delay the loading of the form until Angular is fully loaded.

I simply added ng-init in the app and use ng-if at the form side to check if the variable I set is already loaded.

<div ng-app="myApp" ng-init="loaded='yes'"> 
   <form ng-if="loaded.length > 0">
      <!--all my elements here-->
   </form>
</div>

you can do it by two simple point and change in your code

1.In your xml in anim folder of your project, Set the fade in and fade out duration time not equal

2.In you java class before the start of fade out animation, set second imageView visibility Gone then after fade out animation started set second imageView visibility which you want to fade in visible

fadeout.xml

<alpha
    android:duration="4000"
    android:fromAlpha="1.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="0.0" />

fadein.xml

<alpha
    android:duration="6000"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="1.0" />

In you java class

Animation animFadeOut = AnimationUtils.loadAnimation(this, R.anim.fade_out);
    ImageView iv = (ImageView) findViewById(R.id.imageView1);
    ImageView iv2 = (ImageView) findViewById(R.id.imageView2);
    iv.setVisibility(View.VISIBLE);
    iv2.setVisibility(View.GONE);
    animFadeOut.reset();
    iv.clearAnimation();
    iv.startAnimation(animFadeOut);

    Animation animFadeIn = AnimationUtils.loadAnimation(this, R.anim.fade_in);
    iv2.setVisibility(View.VISIBLE);
    animFadeIn.reset();
    iv2.clearAnimation();
    iv2.startAnimation(animFadeIn);

var imgSrc, imgW, imgH;
function myFunction(image){
    var img = new Image();
    img.src = image;
    img.onload = function() {   
        return {
            src:image,
            width:this.width,
            height:this.height};
        }
    return img;
}
var x = myFunction('http://www.google.com/intl/en_ALL/images/logo.gif');
    //Waiting for the image loaded. Otherwise, system returned 0 as both width and height.
x.addEventListener('load',function(){
    imgSrc = x.src;
    imgW = x.width;
    imgH = x.height;
});
x.addEventListener('load',function(){
    console.log(imgW+'x'+imgH);//276x110
});
console.log(imgW);//undefined.
console.log(imgH);//undefined.
console.log(imgSrc);//undefined.

This is my method, hope this helpful. :)

I'm having the same problem to solve, because I need to install JDK8 to run Android SDK Manager (because it seems that don't work well with JDK9). However, I tell you how I solve all problems on a Mac (Sierra).

First, you need brew with cask and jenv.

1. You can find an useful guide here,Homebrew Cask Installation Guide. Remember to tap 'caskroom/versions' running in the terminal: brew tap caskroom/versions
2. After that, install jenv with: brew install jenv
3. Install whatever version you want with cask brew cask install java8 (or java7 or java if you want to install the latest version, jdk9)
4. The last step is to configure which version to run (and let jenv to manage your JAVA_HOME) jenv versions to list all versions installed on your machine and then activate the one you want with jenv global [JDK_NAME_OF_LIST]

You could find other useful informations here on this Github Gist brew-java-and-jenv.md, on this blog Install multiple JDK on a Mac and on Jenv Website

Another option is using threads with function pointers:

#include <iostream>
#include <thread> // this_thread::sleep_for() and thread objects
#include <chrono> // chrono::milliseconds()

bool stopWaitingFlag = false;

void delayms(int millisecondsToSleep) 
{
  std::this_thread::sleep_for(std::chrono::milliseconds(millisecondsToSleep));
}

void WaitForKey() 
{
  while (stopWaitingFlag == false)
  {
    std::cout<<"Display from the thread function"<<std::endl;
    delayms(1000);
  }
}

 

int main()
{
  std::thread threadObj(&WaitForKey);

  char userInput = '\0';
  while (userInput != 'y')
  {
    std::cout << "\e[1;31mWaiting for a key, Enter 'y' for yes\e[0m" << std::endl;
    std::cin >> userInput;
    if (userInput == 'y') {
      stopWaitingFlag = true;
    }
  }
  if (threadObj.joinable())
    threadObj.join();

  std::cout<<"Exit of Main function"<<std::endl;
  return 0;
}

There are several ways to UPDATE using sqlalchemy

1) for c in session.query(Stuff).all():
       c.foo += 1
   session.commit()

2) session.query().\
       update({"foo": (Stuff.foo + 1)})
   session.commit()

3) conn = engine.connect()
   stmt = Stuff.update().\
       values(Stuff.foo = (Stuff.foo + 1))
   conn.execute(stmt)

Here's a short snippet using subprocess. The check_call method either returns 0 for success, or raises an exception. This way, I don't have to parse the output of ping. I'm using shlex to split the command line arguments.

  import subprocess
  import shlex

  command_line = "ping -c 1 www.google.comsldjkflksj"
  args = shlex.split(command_line)
  try:
      subprocess.check_call(args,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
      print "Website is there."
  except subprocess.CalledProcessError:
      print "Couldn't get a ping."

This is my benchmark results

test 4,267,740 ops/sec ±1.32% (60 runs sampled)

exec 3,649,719 ops/sec ±2.51% (60 runs sampled)

match 3,623,125 ops/sec ±1.85% (62 runs sampled)

indexOf 6,230,325 ops/sec ±0.95% (62 runs sampled)

test method is faster than the match method, but the fastest method is the indexOf

when you add context:component-scan for the first time in an xml, the following needs to be added.

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

AFAIK, you can't create a File from an assets file because these are stored in the apk, that means there is no path to an assets folder.

But, you can try to create that File using a buffer and the AssetManager (it provides access to an application's raw asset files).

Try to do something like:

AssetManager am = getAssets();
InputStream inputStream = am.open("myfoldername/myfilename");
File file = createFileFromInputStream(inputStream);

private File createFileFromInputStream(InputStream inputStream) {

   try{
      File f = new File(my_file_name);
      OutputStream outputStream = new FileOutputStream(f);
      byte buffer[] = new byte[1024];
      int length = 0;

      while((length=inputStream.read(buffer)) > 0) {
        outputStream.write(buffer,0,length);
      }

      outputStream.close();
      inputStream.close();

      return f;
   }catch (IOException e) {
         //Logging exception
   }

   return null;
}

Let me know about your progress.

You could tell wget to not download the contents in a couple of different ways:

wget --spider http://www.example.com/cronit.php

which will just perform a HEAD request but probably do what you want

wget -O /dev/null http://www.example.com/cronit.php

which will save the output to /dev/null (a black hole)

You might want to look at wget's -q switch too which prevents it from creating output

I think that the best option would probably be:

wget -q --spider http://www.example.com/cronit.php

that's unless you have some special logic checking the HTTP method used to request the page

From AngularJS documentation:

params – {Object.} – Map of strings or objects which will be turned to ?key1=value1&key2=value2 after the url. If the value is not a string, it will be JSONified.

So, provide string as parameters. If you don't want that, then use transformations. Again, from the documentation:

To override these transformation locally, specify transform functions as transformRequest and/or transformResponse properties of the config object. To globally override the default transforms, override the $httpProvider.defaults.transformRequest and $httpProvider.defaults.transformResponse properties of the $httpProvider.

Refer to documentation for more details.

I think people here got sidetracked by the UrlEncode message. URLEncoding is not what you want -- you want to encode stuff that won't work as a filename on the target system.

Assuming that you want some generality -- feel free to find the illegal characters on several systems (MacOS, Windows, Linux and Unix), union them to form a set of characters to escape.

As for the escape, a HexEscape should be fine (Replacing the characters with %XX). Convert each character to UTF-8 bytes and encode everything >128 if you want to support systems that don't do unicode. But there are other ways, such as using back slashes "\" or HTML encoding """. You can create your own. All any system has to do is 'encode' the uncompatible character away. The above systems allow you to recreate the original name -- but something like replacing the bad chars with spaces works also.

On the same tangent as above, the only one to use is

Uri.EscapeDataString

-- It encodes everything that is needed for OAuth, it doesn't encode the things that OAuth forbids encoding, and encodes the space as %20 and not + (Also in the OATH Spec) See: RFC 3986. AFAIK, this is the latest URI spec.

t(sapply(a, '[', 1:max(sapply(a, length))))

where 'a' is a list. Would work for unequal row size

You maybe wanted to do the following:

foreach($user->data as $mydata)

    {
         echo $mydata->name . "\n";
         foreach($mydata->values as $values)
         {
              echo $values->value . "\n";
         }
    }        

I am not sure it would read better but you could do the following:

while any((not condition1, not condition2, val == -1)):
    val,something1,something2 = getstuff()

    if something1==10:
        condition1 = True

    if something2==20:
        condition2 = True

Take care though:

If you want to sort the file primarily by field 3, and secondarily by field 2 you want this:

sort -k 3,3 -k 2,2 < inputfile

Not this: sort -k 3 -k 2 < inputfile which sorts the file by the string from the beginning of field 3 to the end of line (which is potentially unique).

-k, --key=POS1[,POS2]     start a key at POS1 (origin 1), end it at POS2
                          (default end of line)

The debate between cssSelector vs XPath would remain as one of the most subjective debate in the Selenium Community. What we already know so far can be summarized as:

• People in favor of cssSelector say that it is more readable and faster (especially when running against Internet Explorer).
• While those in favor of XPath tout it's ability to transverse the page (while cssSelector cannot).
• Traversing the DOM in older browsers like IE8 does not work with cssSelector but is fine with XPath.
• XPath can walk up the DOM (e.g. from child to parent), whereas cssSelector can only traverse down the DOM (e.g. from parent to child)
• However not being able to traverse the DOM with cssSelector in older browsers isn't necessarily a bad thing as it is more of an indicator that your page has poor design and could benefit from some helpful markup.
• Ben Burton mentions you should use cssSelector because that's how applications are built. This makes the tests easier to write, talk about, and have others help maintain.
• Adam Goucher says to adopt a more hybrid approach -- focusing first on IDs, then cssSelector, and leveraging XPath only when you need it (e.g. walking up the DOM) and that XPath will always be more powerful for advanced locators.

Dave Haeffner carried out a test on a page with two HTML data tables, one table is written without helpful attributes (ID and Class), and the other with them. I have analyzed the test procedure and the outcome of this experiment in details in the discussion Why should I ever use cssSelector selectors as opposed to XPath for automated testing?. While this experiment demonstrated that each Locator Strategy is reasonably equivalent across browsers, it didn't adequately paint the whole picture for us. Dave Haeffner in the other discussion Css Vs. X Path, Under a Microscope mentioned, in an an end-to-end test there were a lot of other variables at play Sauce startup, Browser start up, and latency to and from the application under test. The unfortunate takeaway from that experiment could be that one driver may be faster than the other (e.g. IE vs Firefox), when in fact, that's wasn't the case at all. To get a real taste of what the performance difference is between cssSelector and XPath, we needed to dig deeper. We did that by running everything from a local machine while using a performance benchmarking utility. We also focused on a specific Selenium action rather than the entire test run, and run things numerous times. I have analyzed the specific test procedure and the outcome of this experiment in details in the discussion cssSelector vs XPath for selenium. But the tests were still missing one aspect i.e. more browser coverage (e.g., Internet Explorer 9 and 10) and testing against a larger and deeper page.

Dave Haeffner in another discussion Css Vs. X Path, Under a Microscope (Part 2) mentions, in order to make sure the required benchmarks are covered in the best possible way we need to consider an example that demonstrates a large and deep page.

Test SetUp

To demonstrate this detailed example, a Windows XP virtual machine was setup and Ruby (1.9.3) was installed. All the available browsers and their equivalent browser drivers for Selenium was also installed. For benchmarking, Ruby's standard lib benchmark was used.

• Opera:

Analyzing the Results

• Chrome and Firefox are clearly tuned for faster cssSelector performance.
• Internet Explorer 8 is a grab bag of cssSelector that won't work, an out of control XPath traversal that takes ~65 seconds, and a 38 second table traversal with no cssSelector result to compare it against.
• In IE 9 and 10, XPath is faster overall. In Safari, it's a toss up, except for a couple of slower traversal runs with XPath. And across almost all browsers, the nested sibling traversal and table cell traversal done with XPath are an expensive operation.
• These shouldn't be that surprising since the locators are brittle and inefficient and we need to avoid them.

Summary

• Overall there are two circumstances where XPath is markedly slower than cssSelector. But they are easily avoidable.
• The performance difference is slightly in favor of css-selectors for non-IE browsers and slightly in favor of xpath for IE browsers.

Trivia

You can perform the bench-marking on your own, using this library where Dave Haeffner wrapped up all the code.

I have no doubt on @Grant answer. But I face few issues sometimes such as if the column name is similar to any reserved keyword of postgresql such as natural in this case similar SQL is difficult to run from the command line as "\natural\" will be needed in Query field. So my approach is to write the SQL in separate file and run the SQL file from command line. This has another advantage too. If you have to change the query for a large script you do not need to touch the script file or command. Only change the SQL file like this

psql -h localhost -d database -U postgres -p 5432 -a -q -f /path/to/the/file.sql
