That's no problem.

@Html.Partial("../Controller/View", model)

or

@Html.Partial("~/Views/Controller/View.cshtml", model)

Should do the trick.

If you want to pass through the (other) controller, you can use:

@Html.Action("action", "controller", parameters)

or any of the other overloads

You can use:

QString str = "10";
int n = str.toInt();

Output:

n = 10

Below method uploads file in a particular folder in a bucket and return the generated url of the file uploaded.

private String uploadFileToS3Bucket(final String bucketName, final File file) {
    final String uniqueFileName = uploadFolder + "/" + file.getName();
    LOGGER.info("Uploading file with name= " + uniqueFileName);
    final PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, uniqueFileName, file);
    amazonS3.putObject(putObjectRequest);
    return ((AmazonS3Client) amazonS3).getResourceUrl(bucketName, uniqueFileName);
}

1. To be clear: The option "Value for Edit Top Rows command" has nothing to do with the fact if a result set is editable or not. It is just a way to limit the result set.

2. Editing the result set of a query based on one and only one table is obviously always possible.

3. The result set of a query based on more than one table is under following condition possible: You can edit the fields in the result set at once if they belong to one and only one based table in the query! If the fields are Primary Key, then you have to fulfill refresh/"Execute SQL" (Ctrl+R) after each row update, in order to be able to edit a row next time. If the fields are not Primary Key, then you do not need to fulfill refresh/"Execute SQL" (Ctrl+R).

I have tested it on SQL Server 2008 - 2016!

You can do that: Postman -> Import -> Link -> {root_url}/v2/api-docs

If you want to clear the build history of MultiBranchProject (e.g. pipeline), go to your Jenkins home page ? Manage Jenkins ? Script Console and run the following script:

def projectName = "ProjectName"
def project = Jenkins.instance.getItem(projectName)
def jobs = project.getItems().each {
  def job = it
  job.getBuilds().each { it.delete() }
  job.nextBuildNumber = 1
  job.save()
}

Do you need to do it from mgmt studio? Here's how we do it from cmd line:

"C:\Program Files\Microsoft SQL Server\MSSQL\Binn\TEXTCOPY.exe" /S < Server> /D < DataBase> /T mytable /C mypictureblob /F "C:\picture.png" /W"where RecId=" /I

You can use NumberFormat Class object to accomplish the task.

// Creating number format object to set 2 places after decimal point
NumberFormat nf = NumberFormat.getInstance();
nf.setMaximumFractionDigits(2);            
nf.setGroupingUsed(false);

System.out.println(nf.format(precision));// Assuming precision is a double type variable

I think the problem is with the way you designed your data. To me in terms of semantics, it just doesn't make sense. What exactly is steps for?

Does it store the information of one company?

If that's the case steps should be an object (see KayakDave's answer) and each "step" should be an object property.

Does it store the information of multiple companies?

If that's the case, steps should be an array of objects.

$scope.steps=[{companyName: true, businessType: true},{companyName: false}]

In either case you can easily iterate through the data with one (two for 2nd case) ng-repeats.

If you know the folder you want to navigate to, find the index of it then substring.

            var ind = Directory.GetCurrentDirectory().ToString().IndexOf("Folderame");

            string productFolder = Directory.GetCurrentDirectory().ToString().Substring(0, ind);

are you picky with using Unicode because with java its more simple if you write your program to use "dec" value or (HTML-Code) then you can simply cast data types between char and int

char a = 98;
char b = 'b';
char c = (char) (b+0002);

System.out.println(a);
System.out.println((int)b);
System.out.println((int)c);
System.out.println(c);

Gives this output

b
98
100
d

You have to give elevation prop to View

<View elevation={5} style={styles.container}>
   <Text>Hello World !</Text>
 </View>

styles can be added like this:

 const styles = StyleSheet.create({

     container:{
        padding:20,
        backgroundColor:'#d9d9d9',
        shadowColor: "#000000",
        shadowOpacity: 0.8,
        shadowRadius: 2,
        shadowOffset: {
          height: 1,
          width: 1
        }
       },
   })

You could try the classic MySQL world database.

The world.sql file is available for download here:

Just scroll down to Example Databases and you will find it.

I have implemented @satchmorun's suggestion here: https://github.com/andresesfm/angular-underscore-module

To use it:

1. Make sure you have included underscore.js in your project

   <script src="bower_components/underscore/underscore.js">
   

2. Get it:

   bower install angular-underscore-module
   

3. Add angular-underscore-module.js to your main file (index.html)

   <script src="bower_components/angular-underscore-module/angular-underscore-module.js"></script>
   

4. Add the module as a dependency in your App definition

   var myapp = angular.module('MyApp', ['underscore'])
   

5. To use, add as an injected dependency to your Controller/Service and it is ready to use

   angular.module('MyApp').controller('MyCtrl', function ($scope, _) {
   ...
   //Use underscore
   _.each(...);
   ...
   

I was not able to get rsync to connect via ssh on a different port, but I was able to redirect the ssh connection to the computer I wanted via iptables. This is not the solution I was looking for, but it solved my problem.

Believing this performance evaluation, the switch case is faster.

This is the conclusion:

The results show that the switch statement is faster to execute than the if-else-if ladder. This is due to the compiler's ability to optimise the switch statement. In the case of the if-else-if ladder, the code must process each if statement in the order determined by the programmer. However, because each case within a switch statement does not rely on earlier cases, the compiler is able to re-order the testing in such a way as to provide the fastest execution.

For a realistic approach that emulates the most human behavior, you may want to add a referer in your curl options. You may also want to add a follow_location to your curl options. Trust me, whoever said that cURLING Google results is impossible, is a complete dolt and should throw his/her computer against the wall in hopes of never returning to the internetz again. Everything that you can do "IRL" with your own browser can all be emulated using PHP cURL or libCURL in Python. You just need to do more cURLS to get buff. Then you will see what I mean. :)

  $url = "http://www.google.com/search?q=".$strSearch."&hl=en&start=0&sa=N";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_REFERER, 'http://www.example.com/1');
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_VERBOSE, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
  curl_setopt($ch, CURLOPT_URL, urlencode($url));
  $response = curl_exec($ch);
  curl_close($ch);

I posted a somewhat similar question a while back, but regarding a model on CI.

Returning two separate query results within a model function

Although your question is not exactly the same, I believe the solution follows the same principle: if you're proposing to do what you mention in your question, there may be something wrong in the way you're coding and some refactoring could be in order.

The take home message is that what you're asking is not the way to go when working with MVC.

The best practice is to either use a Model to place reusable functions and call them in a controller that outputs the data through a view -- or even better use helpers or libraries (for functions that may be needed repeatedly).

If the indexes are continuous:

foreach ($arr as $key => $val) {
   if (isset($arr[$key+1])) {
      echo $arr[$key+1]; // next element
   } else {
     // end of array reached
   }
}

In urls.py I added this line:

from django.views.static import serve 

add those two urls in urlpatterns:

url(r'^media/(?P<path>.*)$', serve,{'document_root': settings.MEDIA_ROOT}), 
url(r'^static/(?P<path>.*)$', serve,{'document_root': settings.STATIC_ROOT}), 

and both static and media files were accesible when DEBUG=FALSE.
Hope it helps :)

function leapYear(year)
{
  return ((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0);

If your code must run under Python2 and Python3, use the 2to3 six library like this:

import six

six.next(g)  # on PY2K: 'g.next()' and onPY3K: 'next(g)'

As long as you are okay with writing a separate .h/.cpp pair for each queryable enum, this solution works with nearly the same syntax and capabilities as a regular c++ enum:

// MyEnum.h
#include <EnumTraits.h>
#ifndef ENUM_INCLUDE_MULTI
#pragma once
#end if

enum MyEnum : int ETRAITS
{
    EDECL(AAA) = -8,
    EDECL(BBB) = '8',
    EDECL(CCC) = AAA + BBB
};

The .cpp file is 3 lines of boilerplate:

// MyEnum.cpp
#define ENUM_DEFINE MyEnum
#define ENUM_INCLUDE <MyEnum.h>
#include <EnumTraits.inl>

Example usage:

for (MyEnum value : EnumTraits<MyEnum>::GetValues())
    std::cout << EnumTraits<MyEnum>::GetName(value) << std::endl;

Code

This solution requires 2 source files:

// EnumTraits.h
#pragma once
#include <string>
#include <unordered_map>
#include <vector>

#define ETRAITS
#define EDECL(x) x

template <class ENUM>
class EnumTraits
{
public:
    static const std::vector<ENUM>& GetValues()
    {
        return values;
    }

    static ENUM GetValue(const char* name)
    {
        auto match = valueMap.find(name);
        return (match == valueMap.end() ? ENUM() : match->second);
    }

    static const char* GetName(ENUM value)
    {
        auto match = nameMap.find(value);
        return (match == nameMap.end() ? nullptr : match->second);
    }

public:
    EnumTraits() = delete;

    using vector_type = std::vector<ENUM>;
    using name_map_type = std::unordered_map<ENUM, const char*>;
    using value_map_type = std::unordered_map<std::string, ENUM>;

private:
    static const vector_type values;
    static const name_map_type nameMap;
    static const value_map_type valueMap;
};

struct EnumInitGuard{ constexpr const EnumInitGuard& operator=(int) const { return *this; } };
template <class T> constexpr T& operator<<=(T&& x, const EnumInitGuard&) { return x; }

...and

// EnumTraits.inl
#define ENUM_INCLUDE_MULTI

#include ENUM_INCLUDE
#undef ETRAITS
#undef EDECL

using EnumType = ENUM_DEFINE;
using TraitsType = EnumTraits<EnumType>;
using VectorType = typename TraitsType::vector_type;
using NameMapType = typename TraitsType::name_map_type;
using ValueMapType = typename TraitsType::value_map_type;
using NamePairType = typename NameMapType::value_type;
using ValuePairType = typename ValueMapType::value_type;

#define ETRAITS ; const VectorType TraitsType::values
#define EDECL(x) EnumType::x <<= EnumInitGuard()
#include ENUM_INCLUDE
#undef ETRAITS
#undef EDECL

#define ETRAITS ; const NameMapType TraitsType::nameMap
#define EDECL(x) NamePairType(EnumType::x, #x) <<= EnumInitGuard()
#include ENUM_INCLUDE
#undef ETRAITS
#undef EDECL

#define ETRAITS ; const ValueMapType TraitsType::valueMap
#define EDECL(x) ValuePairType(#x, EnumType::x) <<= EnumInitGuard()
#include ENUM_INCLUDE
#undef ETRAITS
#undef EDECL

Explanation

This implementation exploits the fact that the braced list of elements of an enum definition can also be used as a braced initializer list for class member initialization.

When ETRAITS is evaluated in the context of EnumTraits.inl, it expands out to a static member definition for the EnumTraits<> class.

The EDECL macro transforms each enum member into initializer list values which subsequently get passed into the member constructor in order to populate the enum info.

The EnumInitGuard class is designed to consume the enum initializer values and then collapse - leaving a pure list of enum data.

Benefits

• c++-like syntax
• Works identically for both enum and enum class (*almost)
• Works for enum types with any numeric underlying type
• Works for enum types with automatic, explicit, and fragmented initializer values
• Works for mass renaming (intellisense linking preserved)
• Only 5 preprocessor symbols (3 global)

* In contrast to enums, initializers in enum class types that reference other values from the same enum must have those values fully qualified

Disbenefits

• Requires a separate .h/.cpp pair for each queryable enum
• Depends on convoluted macro and include magic
• Minor syntax errors explode into much larger errors
• Defining class or namespace scoped enums is nontrivial
• No compile time initialization

Comments

Intellisense will complain a bit about private member access when opening up EnumTraits.inl, but since the expanded macros are actually defining class members, that isn't actually a problem.

The #ifndef ENUM_INCLUDE_MULTI block at the top of the header file is a minor annoyance that could probably be shrunken down into a macro or something, but it's small enough to live with at its current size.

Declaring a namespace scoped enum requires that the enum first be forward declared inside its namespace scope, then defined in the global namespace. Additionally, any enum initializers using values of the same enum must have those values fully qualified.

namespace ns { enum MyEnum : int; }
enum ns::MyEnum : int ETRAITS
{
    EDECL(AAA) = -8,
    EDECL(BBB) = '8',
    EDECL(CCC) = ns::MyEnum::AAA + ns::MyEnum::BBB
}

In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.

But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:

{ Id: 1, 
name:'john', 
phones:[{title:'home',number:111111,...},
        {title:'office',number:22222,...}]
}

sends

{ Id: 1, 
name:'john', 
phones:[object object]
phones:[object object]
}

This query i have generated for inserting the Excel file data into database In this id and price are numeric values and date field as well. This query summarized all the type which I require It may useful to you as well

Eorekan had the answer but only got myself and one other to up vote his answer.

I had a similar issue except the "Server Name" field was disabled.

Found this was due to the Apache Tomcat v7.0 runtime environment pointing to the wrong folder. This was fixed by going to Window - Preferences - Server - Runtime Environments, clicking on the runtime environment entry and clicking "Edit..." and then modifying the Tomcat installation directory.

I uninstalled gradle and reinstalled it and then created a new wrapper.

$ sudo apt remove gradle
$ sudo apt-get install gradle
$ gradle wrapper

Did you check the gsl package in your system. Try with this:

ldconfig-p | grep gsl

If gsl is installed, it will display the configuration path. If it is not in the standard path /usr/lib/ then you need to do the following in bash:

export PATH=$PATH:/your/path/to/gsl-config 

If gsl is not installed, simply do

sudo apt-get install libgsl0ldbl
sudo apt-get install gsl-bin libgsl0-dev

I had a problem with the mvabund package and this fixed the error

Cheers!

Waking up an old thread here I see, but I felt the urge to add the "new" .xlsx format.

According to http://filext.com/file-extension/XLSX the extension for .xlsx is application/vnd.openxmlformats-officedocument.spreadsheetml.sheet. It might be a good idea to include it when checking for mime types!

ini_set('memory_limit', '-1');

The terminal-only (and simplest) solution, in case all those fancy UI's fail to install or to run:
ignore cProfile completely and replace it with pyinstrument, that will collect and display the tree of calls right after execution.

Install:

$ pip install pyinstrument

Profile and display result:

$ python -m pyinstrument ./prog.py

Works with python2 and 3.

[EDIT] The documentation of the API, for profiling only a part of the code, can be found here.

using position:fixed alone is just fine when you don't have a header or logo at the top of your page. This solution will take into account the how far the window has scrolled, and moves the div when you scrolled past your header. It will then lock it back into place when you get to the top again.

if($(window).scrollTop() > Height_of_Header){
    //begin to scroll
    $("#div").css("position","fixed");
    $("#div").css("top",0);
}
else{
    //lock it back into place
    $("#div").css("position","relative");
}

DATEDIFF but note it returns an integer so if you need fractions of hours use something like this:-

CAST(DATEDIFF(ss, startDate, endDate) AS decimal(precision, scale)) / 3600

The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.

The question asked is just a type conversion question and here its conversion from int data type to float data type and for that you can do it by the function :

float()

And for more details you can visit this page.

The following is a concise (and updated) summation of the earlier solutions. Here's what to do:

Add these strings and their respective parent keys:

pwrshell\(Default) < Open PowerShell Here
pwrshell\command\(Default) < powershell -NoExit -Command Set-Location -LiteralPath '%V'
pwrshelladmin\(Default) < Open PowerShell (Admin)
pwrshelladmin\command\(Default) < powershell -Command Start-Process -verb runAs -ArgumentList '-NoExit','cd','%V' powershell

at these locations

HKCR\Directory\shell (for folders)
HKCR\Directory\Background\shell (Explorer window)
HKCR\Drive\shell (for root drives)

That's it. Add the "Extended" strings for the commands only to be visible if you hold the "Shift" key, everything else is superfluous.

The above answers will work, but just in case you want a different approach, try classname: https://github.com/JedWatson/classnames

suppose you're posting a html form with this:

<input type="text" name="username">

If using raw cgi:

import cgi
form = cgi.FieldStorage()
print form["username"]

If using Django, Pylons, Flask or Pyramid:

print request.GET['username'] # for GET form method
print request.POST['username'] # for POST form method

Using Turbogears, Cherrypy:

from cherrypy import request
print request.params['username']

Web.py:

form = web.input()
print form.username

Werkzeug:

print request.form['username']

If using Cherrypy or Turbogears, you can also define your handler function taking a parameter directly:

def index(self, username):
    print username

Google App Engine:

class SomeHandler(webapp2.RequestHandler):
    def post(self):
        name = self.request.get('username') # this will get the value from the field named username
        self.response.write(name) # this will write on the document

So you really will have to choose one of those frameworks.

I have a little trick for your problem. But for that you must use javascript. If you detected that the browser is Chrome insert "dummy" options between every options. Give a new class for those "dummy" options and make them disabled. The height of "dummy" options you can define with font-size property.

CSS:

option.dummy-option-for-chrome {
  font-size:2px;
  color:transparent;
}

Script:

function prepareHtml5Selects() {

  var is_chrome = /chrome/.test( navigator.userAgent.toLowerCase() );
  if(!is_chrome) return;

  $('select > option').each(function() {
    $('<option class="dummy-option-for-chrome" disabled></option>')
     .insertBefore($(this));
  });
  $('<option class="dummy-option-for-chrome" disabled></option>')
    .insertAfter($('select > option:last-child'));
}

#!/usr/bin/env bash

echo name of script is $0
echo first argument is $1
echo second argument is $2
echo seventeenth argument is $17
echo number of arguments is $#

Edit: please see my comment on question

You can use this syntax:

if myItem in list:
    # do something

Also, inverse operator:

if myItem not in list:
    # do something

It's work fine for lists, tuples, sets and dicts (check keys).

Note that this is an O(n) operation in lists and tuples, but an O(1) operation in sets and dicts.

I realize that this is an old post, but sometimes I find it useful to #define constants like these so I do not have to worry about it:

#define DEVICE_SIZE [[[[UIApplication sharedApplication] keyWindow] rootViewController].view convertRect:[[UIScreen mainScreen] bounds] fromView:nil].size

The above constant should return the correct size no matter the device orientation. Then getting the dimensions is as simple as:

lCurrentWidth = DEVICE_SIZE.width;
lCurrentHeight = DEVICE_SIZE.height;

Using cwolves' answer, but not using a closure nor a pre-computed hash :

// Golfed it a bit, too...
function readCookie(n){
  var c = document.cookie.split('; '),
      i = c.length,
      C;

  for(; i>0; i--){
     C = c[i].split('=');
     if(C[0] == n) return C[1];
  }
}

...and minifying...

function readCookie(n){var c=document.cookie.split('; '),i=c.length,C;for(;i>0;i--){C=c[i].split('=');if(C[0]==n)return C[1];}}

...equals 127 bytes.

The usual error is one tries to put Content-Type: {multipart/form-data} into the header of the post request. That will fail, it is best to let Postman do it for you. For example:

Suggestion To Load Via Postman

Fails If In Header

Works

If you must, this is how you can do it in a for loop:

mylist = ['first', 'second', 'other']
endstring = ''
for s in mylist:
  endstring += s

but you should consider using join():

''.join(mylist)

I don't know if this is really any different, but rather than iterate over the query cursor, you could do something like this:

query.exec(function (err, results){
  if (err) res.writeHead(500, err.message)
  else if (!results.length) res.writeHead(404);
  else {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.write(JSON.stringify(results.map(function (msg){ return {msgId: msg.fileName}; })));
  }
  res.end();
});

In cpp, you need to pay special attention to string types when using execvp:

#include <iostream>
#include <string>
#include <cstring>
#include <stdio.h>
#include <unistd.h>
using namespace std;

const size_t MAX_ARGC = 15; // 1 command + # of arguments
char* argv[MAX_ARGC + 1]; // Needs +1 because of the null terminator at the end
// c_str() converts string to const char*, strdup converts const char* to char*
argv[0] = strdup(command.c_str());

// start filling up the arguments after the first command
size_t arg_i = 1;
while (cin && arg_i < MAX_ARGC) {
    string arg;
    cin >> arg;
    if (arg.empty()) {
        argv[arg_i] = nullptr;
        break;
    } else {
        argv[arg_i] = strdup(arg.c_str());
    }
    ++arg_i;
}

// Run the command with arguments
if (execvp(command.c_str(), argv) == -1) {
    // Print error if command not found
    cerr << "command '" << command << "' not found\n";
}

Reference: execlp?execvp?????

I had the same problem.

Here is a workaround

android:inputType="textNoSuggestions|textVisiblePassword"
android:maxLength="6"

Thx to How can I turnoff suggestions in EditText?

You have already executed your query here

$sql = mysql_query("UPDATE anstalld SET mandag = '$mandag', tisdag = '$tisdag', onsdag = '$onsdag', torsdag = '$torsdag', fredag = '$fredag' WHERE namn = '$namn'");

So this line has the problem

$retval = mysql_query( $sql, $conn ); //$sql is not a query its a result set here

Try something like this:

$sql = "UPDATE anstalld SET mandag = '$mandag', tisdag = '$tisdag', onsdag = '$onsdag', torsdag = '$torsdag', fredag = '$fredag' WHERE namn = '$namn'";    
$retval = mysql_query( $sql, $conn ); //execute your query

As a sidenote: MySQL_* extension is deprecated use MySQLi_* or PDO instead.

How about this one.

fields = Model._meta.fields

window.open('https://support.wwf.org.uk', '_blank');

The second parameter is what makes it open in a new window. Don't forget to read Jakob Nielsen's informative article :)

In Oracle 12c onward you could do something like,

CREATE TABLE MAPS
(
  MAP_ID INTEGER GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1) NOT NULL,
  MAP_NAME VARCHAR(24) NOT NULL,
  UNIQUE (MAP_ID, MAP_NAME)
);

And in Oracle (Pre 12c).

-- create table
CREATE TABLE MAPS
(
  MAP_ID INTEGER NOT NULL ,
  MAP_NAME VARCHAR(24) NOT NULL,
  UNIQUE (MAP_ID, MAP_NAME)
);

-- create sequence
CREATE SEQUENCE MAPS_SEQ;

Between the opening and closing tag in our case textarea tag shouldn't be space or newline character or any text(value).

If there's space, newline character or any text, it's considered as value which overrides placeholder.

    **PlaceHolder Appears**
    <textarea placeholder="Am Default Message"></textarea>

    **PlaceHolder Doesn't Appear**

    <textarea placeholder="Am Default Message">  </textarea>
   <textarea placeholder="Am Default Message"> 
   </textarea>
   <textarea placeholder="Am Default Message">Something</textarea>

You can use something like this:

RewriteEngine on
RewriteRule ^.+$ /index.php [L]

This will redirect every query to the root directory's index.php. Note that it will also redirect queries for files that exist, such as images, javascript files or style sheets.

My Point , IN this arent way asking developer to create all environment related in single go, resulting in risk of exposing Production Configuration to end developer

as per 12-Factor, shouldnt be enviornment specific reside in Enviornment only .

How do we do for CI CD

• Build Spring one time and promote to aother environment, in that case, if we have spring jar has all environment, it iwll security risk, having all environment variable in GIT

In a second level cache, domain hbm files can be of key mutable and value false. For example, In this domain class some of the duration in a day remains constant as the universal truth. So, it can be marked as immutable across application.

If you imagine the class hierarchy as a tree (as it is in Java), abstract classes can only be branches and final classes are those that can only be leafs. Classes that fall into neither of those categories can be both branches and leafs.

There's no violation of OO principles here, final is simply providing a nice symmetry.

In practice you want to use final if you want your objects to be immutable or if you're writing an API, to signal to the users of the API that the class is just not intended for extension.

I'll assume you want to check a string value. One nice way is the REGEXP operator, matching the string to a regular expression. Simply do

select field from table where field REGEXP '^-?[0-9]+$';

this is reasonably fast. If your field is numeric, just test for

ceil(field) = field

instead.

setTimeout('$("#someDivId").hide()',1500);

Basically like this,

<?php
$link = ""; // Link goes here!
print "<a href="'.$link.'">Link</a>";
?>

It's OK, I got it! Thanks for your help!

Here is the code to do it:

private void button1_Click(object sender, EventArgs e)
{
    selectedServer = "JS000943";
    listBox1.Items.Add(GetProcessorIdleTime(selectedServer).ToString());
}

private static int GetProcessorIdleTime(string selectedServer)
{
    try
    {
        var searcher = new
           ManagementObjectSearcher
             (@"\\"+ selectedServer +@"\root\CIMV2",
              "SELECT * FROM Win32_PerfFormattedData_PerfOS_Processor WHERE Name=\"_Total\"");

        ManagementObjectCollection collection = searcher.Get();
        ManagementObject queryObj = collection.Cast<ManagementObject>().First();

        return Convert.ToInt32(queryObj["PercentIdleTime"]);
    }
    catch (ManagementException e)
    {
        MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
    }
    return -1;
}

also this works too

SELECT replace(replace(replace(convert(varchar, getdate(), 120),':',''),'-',''),' ','')

I have a slightly different approach that might be useful/more beneficial to some.

Under your main project folder, create a resource folder. Your folder structure should look something like this.

• Project Folder
  • build
  • dist
  • lib
  • nbproject
  • resources
  • src

Go to the properties of your project. You can do this by right clicking on your project in the Projects tab window and selecting Properties in the drop down menu.

Under categories on the left side, select Sources.

In Source Package Folders on the right side, add your resource folder using the Add Folder button. Once you click OK, you should see a Resources folder under your project.

You should now be able to pull resources using this line or similar approach:

MyClass.class.getResource("/main.jpg");

If you were to create a package called Images under the resources folder, you can retrieve the resource like this:

MyClass.class.getResource("/Images/main.jpg");

For Jackson 1.9, We can use the following code for pretty print.

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.enable(SerializationConfig.Feature.INDENT_OUTPUT);

(a) wwww.somewebsite.com/a.txt isn't a 'file URL'. It isn't a URL at all. If you put http:// on the front of it it would be an HTTP URL, which is clearly what you intend here.

(b) FileInputStream is for files, not URLs.

(c) The way to get an input stream from any URL is via URL.openStream(), or URL.getConnection().getInputStream(), which is equivalent but you might have other reasons to get the URLConnection and play with it first.

Running rails g migration AddUserRefToSponsors user:references will generate the following migration:

def change
  add_reference :sponsors, :user, index: true
end

Unfortunately there is no way to insert into the middle of a file without re-writing it. As previous posters have indicated, you can append to a file or overwrite part of it using seek but if you want to add stuff at the beginning or the middle, you'll have to rewrite it.

This is an operating system thing, not a Python thing. It is the same in all languages.

What I usually do is read from the file, make the modifications and write it out to a new file called myfile.txt.tmp or something like that. This is better than reading the whole file into memory because the file may be too large for that. Once the temporary file is completed, I rename it the same as the original file.

This is a good, safe way to do it because if the file write crashes or aborts for any reason, you still have your untouched original file.

I think LayeredPane is your best bet here. You would need a third panel though to contain A and B. This third panel would be the layeredPane and then panel A and B could still have a nice LayoutManagers. All you would have to do is center B over A and there is quite a lot of examples in the Swing trail on how to do this. Tutorial for positioning without a LayoutManager.

public class Main {
    private JFrame frame = new JFrame();
    private JLayeredPane lpane = new JLayeredPane();
    private JPanel panelBlue = new JPanel();
    private JPanel panelGreen = new JPanel();
    public Main()
    {
        frame.setPreferredSize(new Dimension(600, 400));
        frame.setLayout(new BorderLayout());
        frame.add(lpane, BorderLayout.CENTER);
        lpane.setBounds(0, 0, 600, 400);
        panelBlue.setBackground(Color.BLUE);
        panelBlue.setBounds(0, 0, 600, 400);
        panelBlue.setOpaque(true);
        panelGreen.setBackground(Color.GREEN);
        panelGreen.setBounds(200, 100, 100, 100);
        panelGreen.setOpaque(true);
        lpane.add(panelBlue, new Integer(0), 0);
        lpane.add(panelGreen, new Integer(1), 0);
        frame.pack();
        frame.setVisible(true);
    }


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main();
    }

}

You use setBounds to position the panels inside the layered pane and also to set their sizes.

Edit to reflect changes to original post You will need to add component listeners that detect when the parent container is being resized and then dynamically change the bounds of panel A and B.

Petruza,

Instead of using keystroke use key code.
The following example should work for you.

tell application "System Events"
    tell application process "Terminal"
        set frontmost to true
        key code {2, 0, 17, 14}
        keystroke return
    end tell
end tell

The above example will send the characters {d a t e} to Terminal and then
keystroke return will enter and run the command. Use the above example
with whatever key codes you need and you'll be able to do what you're trying to do.

I did so

Field in model:

[Required]
[Display(Name = "User name")]
public string UserName { get; set; }

Razor:

<li>
  @Html.TextBoxFor(m => m.UserName, new { placeholder = Html.DisplayNameFor(n => n.UserName)})
</li>

As Seth stated thread safe means that a method or class instance can be used by multiple threads at the same time without any problems occuring.

Consider the following method:

private int myInt = 0;
public int AddOne()
{
    int tmp = myInt;
    tmp = tmp + 1;
    myInt = tmp;
    return tmp;
}

Now thread A and thread B both would like to execute AddOne(). but A starts first and reads the value of myInt (0) into tmp. Now for some reason the scheduler decides to halt thread A and defer execution to thread B. Thread B now also reads the value of myInt (still 0) into it's own variable tmp. Thread B finishes the entire method, so in the end myInt = 1. And 1 is returned. Now it's Thread A's turn again. Thread A continues. And adds 1 to tmp (tmp was 0 for thread A). And then saves this value in myInt. myInt is again 1.

So in this case the method AddOne() was called two times, but because the method was not implemented in a thread safe way the value of myInt is not 2, as expected, but 1 because the second thread read the variable myInt before the first thread finished updating it.

Creating thread safe methods is very hard in non trivial cases. And there are quite a few techniques. In Java you can mark a method as synchronized, this means that only one thread can execute that method at a given time. The other threads wait in line. This makes a method thread safe, but if there is a lot of work to be done in a method, then this wastes a lot of time. Another technique is to 'mark only a small part of a method as synchronized' by creating a lock or semaphore, and locking this small part (usually called the critical section). There are even some methods that are implemented as lockless thread safe, which means that they are built in such a way that multiple threads can race through them at the same time without ever causing problems, this can be the case when a method only executes one atomic call. Atomic calls are calls that can't be interrupted and can only be done by one thread at a time.

Java doesn't have a general purpose define preprocessor directive.

In the case of constants, it is recommended to declare them as static finals, like in

private static final int PROTEINS = 100;

Such declarations would be inlined by the compilers (if the value is a compile-time constant).

Please note also that public static final constant fields are part of the public interface and their values shouldn't change (as the compiler inlines them). If you do change the value, you would need to recompile all the sources that referenced that constant field.

In my recent project my task was to clean an entire database by using sql statement and each table having many constraints like Primary Key and Foreign Key. There are more than 1000 tables in database so its not possible to write a delete query on each and ever table.

By using a stored procedure named sp_MSForEachTable which allows us to easily process some code against each and every table in a single database. It means that it is used to process a single T-SQL command or a different T-SQL commands against every table in the database.

So follow the below steps to truncate all tables in a SQL Server Database:

Step 1- Disable all constraints on the database by using below sql query :

EXEC sys.sp_msforeachtable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'

Step 2- Execute a Delete or truncate operation on each table of the database by using below sql command :

EXEC sys.sp_msforeachtable 'DELETE FROM ?'

Step 3- Enable all constraints on the database by using below sql statement:

EXEC sys.sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'

<html>
    <head>
        <title>Login page</title>
    </head>

        <h1>Simple Login Page</h1>
        <form name="login">
            Username<input type="text" name="userid"/>
            Password<input type="password" name="pswrd"/>
            <input type="button" onclick="check(this.form)" value="Login"/>
            <input type="reset" value="Cancel"/>
        </form>
        <script language="javascript">
            function check(form) { /*function to check userid & password*/
                /*the following code checkes whether the entered userid and password are matching*/
                if(form.userid.value == "myuserid" && form.pswrd.value == "mypswrd") {
                    window.open('target.html')/*opens the target page while Id & password matches*/
                }
                else {
                    alert("Error Password or Username")/*displays error message*/
                }
            }
        </script>
    </body>
</html>

In your config.xml file add this line:

<preference name="loadUrlTimeoutValue" value="700000" />

Windows 10, 8.1, 8

Open start menu,

1. Type Edit environment variables
2. Open the option Edit the system environment variables
3. Click Environment variables... button
4. There you see two boxes, in System Variables box find path variable
5. Click Edit
6. a window pops up, click New
7. Type the Directory path of your .exe or batch file ( Directory means exclude the file name from path)
8. Click Ok on all open windows and restart your system restart the command prompt.

Passwords in the database should be stored encrypted. One way encryption (hashing) is recommended, such as SHA2, SHA2, WHIRLPOOL, bcrypt DELETED: MD5 or SHA1. (those are older, vulnerable

In addition to that you can use additional per-user generated random string - 'salt':

$salt = MD5($this->createSalt());

$Password = SHA2($postData['Password'] . $salt);

createSalt() in this case is a function that generates a string from random characters.

EDIT: or if you want more security, you can even add 2 salts: $salt1 . $pass . $salt2

Another security measure you can take is user inactivation: after 5 (or any other number) incorrect login attempts user is blocked for x minutes (15 mins lets say). It should minimize success of brute force attacks.

Here is the solution for c# MVC:

1. First : Create a custom attribute and override method like this:

   public class CultureAttribute : ActionFilterAttribute
   {
       public override void OnActionExecuting(ActionExecutingContext filterContext)
       {
           // Retreive culture from GET
           string currentCulture = filterContext.HttpContext.Request.QueryString["culture"];
   
           // Also, you can retreive culture from Cookie like this :
           //string currentCulture = filterContext.HttpContext.Request.Cookies["cookie"].Value;
   
           // Set culture
           Thread.CurrentThread.CurrentCulture = new CultureInfo(currentCulture);
           Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(currentCulture);
       }
   }
   

2. Second : In App_Start, find FilterConfig.cs, add this attribute. (this works for WHOLE application)

   public class FilterConfig
   {
       public static void RegisterGlobalFilters(GlobalFilterCollection filters)
       {
           // Add custom attribute here
           filters.Add(new CultureAttribute());
       }
   }    
   

That's it !

If you want to define culture for each controller/action in stead of whole application, you can use this attribute like this:

[Culture]
public class StudentsController : Controller
{
}

Or:

[Culture]
public ActionResult Index()
{
    return View();
}

In case anyone else is interested: I needed a class that could be used interchangeably wherever either a string or wstring was expected. The following class convertible_string, based on dk123's solution, can be initialized with either a string, char const*, wstring or wchar_t const* and can be assigned to by or implicitly converted to either a string or wstring (so can be passed into a functions that take either).

class convertible_string
{
public:
    // default ctor
    convertible_string()
    {}

    /* conversion ctors */
    convertible_string(std::string const& value) : value_(value)
    {}
    convertible_string(char const* val_array) : value_(val_array)
    {}
    convertible_string(std::wstring const& wvalue) : value_(ws2s(wvalue))
    {}
    convertible_string(wchar_t const* wval_array) : value_(ws2s(std::wstring(wval_array)))
    {}

    /* assignment operators */
    convertible_string& operator=(std::string const& value)
    {
        value_ = value;
        return *this;
    }
    convertible_string& operator=(std::wstring const& wvalue)
    {
        value_ = ws2s(wvalue);
        return *this;
    }

    /* implicit conversion operators */
    operator std::string() const { return value_; }
    operator std::wstring() const { return s2ws(value_); }
private:
    std::string value_;
};

If you simply need to get the basic snapshot of the files + folders. Follow these baby steps:

• Press Windows + R
• Press Enter
• Type cmd
• Press Enter
• Type dir -s
• Press Enter

I thought I'd add my approach, in the context of a practical example. I use a similar check when dealing with values going in and coming out of Memjs, so even though the value saved may be string, array or object, Memjs expects a string. The function first checks if a key/value pair already exists, if it does then a precheck is done to determine if value needs to be parsed before being returned:

  function checkMem(memStr) {
    let first = memStr.slice(0, 1)
    if (first === '[' || first === '{') return JSON.parse(memStr)
    else return memStr
  }

Otherwise, the callback function is invoked to create the value, then a check is done on the result to see if the value needs to be stringified before going into Memjs, then the result from the callback is returned.

  async function getVal() {
    let result = await o.cb(o.params)
    setMem(result)
    return result

    function setMem(result) {
      if (typeof result !== 'string') {
        let value = JSON.stringify(result)
        setValue(key, value)
      }
      else setValue(key, result)
    }
  }

The complete code is below. Of course this approach assumes that the arrays/objects going in and coming out are properly formatted (i.e. something like "{ key: 'testkey']" would never happen, because all the proper validations are done before the key/value pairs ever reach this function). And also that you are only inputting strings into memjs and not integers or other non object/arrays-types.

async function getMem(o) {
  let resp
  let key = JSON.stringify(o.key)
  let memStr = await getValue(key)
  if (!memStr) resp = await getVal()
  else resp = checkMem(memStr)
  return resp

  function checkMem(memStr) {
    let first = memStr.slice(0, 1)
    if (first === '[' || first === '{') return JSON.parse(memStr)
    else return memStr
  }

  async function getVal() {
    let result = await o.cb(o.params)
    setMem(result)
    return result

    function setMem(result) {
      if (typeof result !== 'string') {
        let value = JSON.stringify(result)
        setValue(key, value)
      }
      else setValue(key, result)
    }
  }
}

It's either through system property

-Dorg.slf4j.simpleLogger.defaultLogLevel=debug

or simplelogger.properties file on the classpath

see http://www.slf4j.org/api/org/slf4j/impl/SimpleLogger.html for details

Set the step attribute to 1:

<input type="number" step="1" />

This seems a bit buggy in Chrome right now so it might not be the best solution at the moment.

A better solution is to use the pattern attribute, that uses a regular expression to match the input:

<input type="text" pattern="\d*" />

\d is the regular expression for a number, * means that it accepts more than one of them. Here is the demo: http://jsfiddle.net/b8NrE/1/

The use of @Qualifier will solve the issue.
Explained as below example : 
public interface PersonType {} // MasterInterface

@Component(value="1.2") 
public class Person implements  PersonType { //Bean implementing the interface
@Qualifier("1.2")
    public void setPerson(PersonType person) {
        this.person = person;
    }
}

@Component(value="1.5")
public class NewPerson implements  PersonType { 
@Qualifier("1.5")
    public void setNewPerson(PersonType newPerson) {
        this.newPerson = newPerson;
    }
}

Now get the application context object in any component class :

Object obj= BeanFactoryAnnotationUtils.qualifiedBeanOfType((ctx).getAutowireCapableBeanFactory(), PersonType.class, type);//type is the qualifier id

you can the object of class of which qualifier id is passed.

The attribute selector syntax is [name=value] where name is the attribute name and value is the attribute value.

So if you want to select all input elements with the attribute name having the value inputName[]:

$('input[name="inputName[]"]')

And if you want to check for two attributes (here: name and value):

$('input[name="inputName[]"][value=someValue]')

Lets Think this is your HTML Form in step2.php

step2.php

<form name="new user" method="post" action="step2_check.php"> 
    <input type="text" name="mail"/> <br />
    <input type="password" name="password"/><br />
    <input type="submit"  value="continue"/>
</form>

I think you need it for your database, so you can assign your HTML Form Value to php Variable, now you can use Real Escape String and below must be your

step2_check.php

if(isset($_POST['mail']) && !empty($_POST['mail']))
{
$mail = mysqli_real_escape_string($db, $_POST['mail']);
}

Where $db is your Database Connection.

If you use GUID as primary key and create clustered index then I suggest use the default of NEWSEQUENTIALID() value for it.

Another way is to check the results of

sp_help 'TableName'

(or just highlight the quoted TableName and pres ALT+F1)

With time passing, I just decided to refine my answer. Below is a screenshot of the results that sp_help provides. A have used the AdventureWorksDW2012 DB for this example. There is numerous good information there, and what we are looking for is at the very end - highlighted in green:

<asp:GridView ID="GridView1" AutoGenerateEditButton="True" 
ondatabound="gv_DataBound" runat="server" DataSourceID="SqlDataSource1"
AutoGenerateColumns="False" width="600px">

<Columns>
                <asp:BoundField HeaderText="UserId" 
                DataField="UserId" 
                SortExpression="UserId" ItemStyle-Width="400px"></asp:BoundField>
   </Columns>
</asp:GridView>

By default, cin reads from the input discarding any spaces. So, all you have to do is to use a do while loop to read the input more than one time:

do {
   cout<<"Enter a number, or numbers separated by a space, between 1 and 1000."<<endl;
   cin >> num;

   // reset your variables

   // your function stuff (calculations)
}
while (true); // or some condition

For those who don't want to create any models, use the following code:

var result = JsonConvert.DeserializeObject<
  List<Dictionary<string, 
    Dictionary<string, string>>>>(content);

Note: This doesn't work for your JSON string. This is not a general solution for any JSON structure.

The approach I've found workable is git's submodule system. Using that you can submodule in a given version of the code and upgrading/downgrading is explicit and recorded - never haphazard.

The folder structure I've taken with this is:

+ myproject
++ src
+++ myproject
+++ github.com
++++ submoduled_project of some kind.

Is this role attribute necessary?

Answer: Yes.

• The role attribute is necessary to support Accessible Rich Internet Applications (WAI-ARIA) to define roles in XML-based languages, when the languages do not define their own role attribute.
• Although this is the reason the role attribute is published by the Protocols and Formats Working Group, the attribute has more general use cases as well.

It provides you:

• Accessibility
• Device adaptation
• Server-side processing
• Complex data description,...etc.

Simply use a class literal, i.e. NameOfClass.class

Merely for the purposes of making your program work, take the contents of your main() method and put them in a constructor:

public BookStoreApp2()
{
   // Put contents of main method here
}

Then, in your main() method. Do this:

public void main( String[] args )
{
  new BookStoreApp2();
}

Depending on what you mean by "use them as Strings", you might not want to use an enum here. In most cases, the solution proposed by The Elite Gentleman will allow you to use them through their toString-methods, e.g. in System.out.println(STRING_ONE) or String s = "Hello "+STRING_TWO, but when you really need Strings (e.g. STRING_ONE.toLowerCase()), you might prefer defining them as constants:

public interface Strings{
  public static final String STRING_ONE = "ONE";
  public static final String STRING_TWO = "TWO";      
}

You can use Environment.GetCommandLineArgs() to obtain the arguments and Environment.CommandLine to obtain the actual command line as entered.

Also, you can use Assembly.GetEntryAssembly() or Process.GetCurrentProcess().

However, when debugging, you should be careful as this final example may give your debugger's executable name (depending on how you attach the debugger) rather than your executable, as may the other examples.

You can do like this:

SELECT convert(datetime, convert(date, '27-09-2013', 103), 103) 

My regular question is rather "anything new or changed in repo" so whatchanged comes handy. Found it here.

git whatchanged origin/master -n 1

I experienced this weird error too, after changing letter case in the name of a class. The file was not copied to a tomcat server as expected, I had to delete it manually and redeploy. Maybe because I use case insensitive operating system?

Following worked for me:
<context:property-placeholder location="file:src/resources/spring/AppController.properties"/>

Somehow "classpath:xxx" is not picking the file.

If you're running cPanel/WHM, make sure that IP is whitelisted in the firewall. You will als need to add that IP to the remote SQL IP list in the cPanel account you're trying to connect to.

You may do this with a for loop instead of a while:

max_loop=20
for ((count = 0; count < max_loop; count++)); do
  if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
       echo "Files Present" | mailx -s "File Present"  -r [email protected] [email protected]
       break
  else
       echo "Sleeping for half an hour" | mailx -s "Time to Sleep Now"  -r [email protected] [email protected]
       sleep 1800
  fi
done

if [ "$count" -eq "$max_loop" ]; then
  echo "Maximum number of trials reached" >&2

You can try this cool app available in play store called Html Page Source https://play.google.com/store/apps/details?id=com.scintillar.hps

You can try this code if you are using bootstrap 3:

HTML

<a href="#" id="pop">
    <img id="imageresource" src="http://patyshibuya.com.br/wp-content/uploads/2014/04/04.jpg" style="width: 400px; height: 264px;">
    Click to Enlarge
</a>

<!-- Creates the bootstrap modal where the image will appear -->
<div class="modal fade" id="imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
        <h4 class="modal-title" id="myModalLabel">Image preview</h4>
      </div>
      <div class="modal-body">
        <img src="" id="imagepreview" style="width: 400px; height: 264px;" >
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

JavaScript:

$("#pop").on("click", function() {
   $('#imagepreview').attr('src', $('#imageresource').attr('src')); // here asign the image to the modal when the user click the enlarge link
   $('#imagemodal').modal('show'); // imagemodal is the id attribute assigned to the bootstrap modal, then i use the show function
});

This is the working fiddle. Hope this helps :)

I had same problem and this accepted solution didn't helped me, if someone has same problem you can use my code snippet:

// example of filtering and sharing multiple images with texts
// remove facebook from sharing intents
private void shareFilter(){

    String share = getShareTexts();
    ArrayList<Uri> uris = getImageUris();

    List<Intent> targets = new ArrayList<>();
    Intent template = new Intent(Intent.ACTION_SEND_MULTIPLE);
    template.setType("image/*");
    List<ResolveInfo> candidates = getActivity().getPackageManager().
            queryIntentActivities(template, 0);

    // remove facebook which has a broken share intent
    for (ResolveInfo candidate : candidates) {
        String packageName = candidate.activityInfo.packageName;
        if (!packageName.equals("com.facebook.katana")) {
            Intent target = new Intent(Intent.ACTION_SEND_MULTIPLE);
            target.setType("image/*");
            target.putParcelableArrayListExtra(Intent.EXTRA_STREAM,uris);
            target.putExtra(Intent.EXTRA_TEXT, share);
            target.setPackage(packageName);
            targets.add(target);
        }
    }
    Intent chooser = Intent.createChooser(targets.remove(0), "Share Via");
    chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, targets.toArray(new Parcelable[targets.size()]));
    startActivity(chooser);

}

compactitem does the job.

\usepackage{paralist}

...

\begin{compactitem}[$\bullet$]
    \item Element 1
    \item Element 2
\end{compactitem}
\vspace{\baselineskip} % new line after list

I was able to do it with justify-content: space-between on the container

This can be expressed in pseudocode as:

while(n > 0):
    remainder = n%2;
    n = n/2;
    Insert remainder to front of a list or push onto a stack

Print list or stack

As others have pointed out queries will be slower. I'd suggest to add at least an '_ID' column to query by that instead.

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

The Print statement in TSQL is a misunderstood creature, probably because of its name. It actually sends a message to the error/message-handling mechanism that then transfers it to the calling application. PRINT is pretty dumb. You can only send 8000 characters (4000 unicode chars). You can send a literal string, a string variable (varchar or char) or a string expression. If you use RAISERROR, then you are limited to a string of just 2,044 characters. However, it is much easier to use it to send information to the calling application since it calls a formatting function similar to the old printf in the standard C library. RAISERROR can also specify an error number, a severity, and a state code in addition to the text message, and it can also be used to return user-defined messages created using the sp_addmessage system stored procedure. You can also force the messages to be logged.

Your error-handling routines won’t be any good for receiving messages, despite messages and errors being so similar. The technique varies, of course, according to the actual way you connect to the database (OLBC, OLEDB etc). In order to receive and deal with messages from the SQL Server Database Engine, when you’re using System.Data.SQLClient, you’ll need to create a SqlInfoMessageEventHandler delegate, identifying the method that handles the event, to listen for the InfoMessage event on the SqlConnection class. You’ll find that message-context information such as severity and state are passed as arguments to the callback, because from the system perspective, these messages are just like errors.

It is always a good idea to have a way of getting these messages in your application, even if you are just spooling to a file, because there is always going to be a use for them when you are trying to chase a really obscure problem. However, I can’t think I’d want the end users to ever see them unless you can reserve an informational level that displays stuff in the application.

You are comparing doc_val_check with an empty string. You want to assign the empty string to doc_val_check

so it should be this:

doc_val_check = "";

The most popular answer is incomplete:

Since this search will generally be performed only for files from installed packages, yum whatprovides is made blisteringly fast by disabling all external repos (the implicit "installed" repo can't be disabled).

yum --disablerepo=* whatprovides <file>

Cause of the issue:

Arguments property in Execute Process Task available on the Control Flow tab is expecting a value of data type DT_WSTR and not DT_STR.

SSIS 2008 R2 package illustrating the issue and fix:

Create an SSIS package in Business Intelligence Development Studio (BIDS) 2008 R2 and name it as SO_13177007.dtsx. Create a package variable with the following information.

Name   Scope        Data Type  Value
------ ------------ ---------- -----
IdVar  SO_13177007  Int32      123

Drag and drop an Execute Process Task onto the Control Flow tab and name it as Pass arguments

Double-click the Execute Process Task to open the Execute Process Task Editor. Click Expressions page and then click the Ellipsis button against the Expressions property to view the Property Expression Editor.

On the Property Expression Editor, select the property Arguments and click the Ellipsis button against the property to open the Expression Builder.

On the Expression Builder, enter the following expression and click Evaluate Expression. This expression tries to convert the integer value in the variable IdVar to string data type.

(DT_STR, 10, 1252) @[User::IdVar]

Clicking Evaluate Expression will display the following error message because the Arguments property on Execute Process Task expects a value of data type DT_WSTR.

To fix the issue, update the expression as shown below to convert the integer value to data type DT_WSTR. Clicking Evaluate Expression will display the value in the Evaluated value text area.

(DT_WSTR, 10) @[User::IdVar]

References:

To understand the differences between the data types DT_STR and DT_WSTR in SSIS, read the documentation Integration Services Data Types on MSDN. Here are the quotes from the documentation about these two string data types.

DT_STR

A null-terminated ANSI/MBCS character string with a maximum length of 8000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)

DT_WSTR

A null-terminated Unicode character string with a maximum length of 4000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)

In the head section of your html document:

<link rel="stylesheet" type="text/css" href="/path/to/ABCD.css">

Your css file should be css only and not contain any markup.

Put the table in the second image on Sheet2, columns D to F.

In Sheet1, cell D2 use the formula

=iferror(vlookup($A2,Sheet2!$D$1:$F$100,column(A1),false),"")

copy across and down.

Edit: here is a picture. The data is in two sheets. On Sheet1, enter the formula into cell D2. Then copy the formula across to F2 and then down as many rows as you need.

I picked node-sass implementer for libsass because it is based on node.js.

Installing node-sass

• (Prerequisite) If you don't have npm, install Node.js first.
• $ npm install -g node-sass installs node-sass globally -g.

This will hopefully install all you need, if not read libsass at the bottom.

How to use node-sass from Command line and npm scripts

General format:

$ node-sass [options] <input.scss> [output.css]
$ cat <input.scss> | node-sass > output.css

Examples:

1. $ node-sass my-styles.scss my-styles.css compiles a single file manually.
2. $ node-sass my-sass-folder/ -o my-css-folder/ compiles all the files in a folder manually.
3. $ node-sass -w sass/ -o css/ compiles all the files in a folder automatically whenever the source file(s) are modified. -w adds a watch for changes to the file(s).

More usefull options like 'compression' @ here. Command line is good for a quick solution, however, you can use task runners like Grunt.js or Gulp.js to automate the build process.

You can also add the above examples to npm scripts. To properly use npm scripts as an alternative to gulp read this comprehensive article @ css-tricks.com especially read about grouping tasks.

• If there is no package.json file in your project directory running $ npm init will create one. Use it with -y to skip the questions.
• Add "sass": "node-sass -w sass/ -o css/" to scripts in package.json file. It should look something like this:

"scripts": {
    "test" : "bla bla bla",
    "sass": "node-sass -w sass/ -o css/"
 }

• $ npm run sass will compile your files.

How to use with gulp

• $ npm install -g gulp installs Gulp globally.
• If there is no package.json file in your project directory running $ npm init will create one. Use it with -y to skip the questions.
• $ npm install --save-dev gulp installs Gulp locally. --save-dev adds gulp to devDependencies in package.json.
• $ npm install gulp-sass --save-dev installs gulp-sass locally.
• Setup gulp for your project by creating a gulpfile.js file in your project root folder with this content:

'use strict';
var gulp = require('gulp');

A basic example to transpile

Add this code to your gulpfile.js:

var gulp = require('gulp');
var sass = require('gulp-sass');
gulp.task('sass', function () {
  gulp.src('./sass/**/*.scss')
    .pipe(sass().on('error', sass.logError))
    .pipe(gulp.dest('./css'));
});

$ gulp sass runs the above task which compiles .scss file(s) in the sass folder and generates .css file(s) in the css folder.

To make life easier, let's add a watch so we don't have to compile it manually. Add this code to your gulpfile.js:

gulp.task('sass:watch', function () {
  gulp.watch('./sass/**/*.scss', ['sass']);
});

All is set now! Just run the watch task:

$ gulp sass:watch

How to use with Node.js

As the name of node-sass implies, you can write your own node.js scripts for transpiling. If you are curious, check out node-sass project page.

What about libsass?

Libsass is a library that needs to be built by an implementer such as sassC or in our case node-sass. Node-sass contains a built version of libsass which it uses by default. If the build file doesn't work on your machine, it tries to build libsass for your machine. This process requires Python 2.7.x (3.x doesn't work as of today). In addition:

LibSass requires GCC 4.6+ or Clang/LLVM. If your OS is older, this version may not compile. On Windows, you need MinGW with GCC 4.6+ or VS 2013 Update 4+. It is also possible to build LibSass with Clang/LLVM on Windows.

I am not sure if this will work for your situation, but often map is a good answer.

If this was your code with the for loop:

<tbody>
    for (var i=0; i < objects.length; i++) {
        <ObjectRow obj={objects[i]} key={i}>
    }
</tbody>

You could write it like this with map:

<tbody>
    {objects.map(function(object, i){
        return <ObjectRow obj={object} key={i} />;
    })}
</tbody>

ES6 syntax:

<tbody>
    {objects.map((object, i) => <ObjectRow obj={object} key={i} />)}
</tbody>

You can see that your locks are pretty much working as you are using them, if you slow down the process and make them block a bit more. You had the right idea, where you surround critical pieces of code with the lock. Here is a small adjustment to your example to show you how each waits on the other to release the lock.

import threading
import time
import inspect

class Thread(threading.Thread):
    def __init__(self, t, *args):
        threading.Thread.__init__(self, target=t, args=args)
        self.start()

count = 0
lock = threading.Lock()

def incre():
    global count
    caller = inspect.getouterframes(inspect.currentframe())[1][3]
    print "Inside %s()" % caller
    print "Acquiring lock"
    with lock:
        print "Lock Acquired"
        count += 1  
        time.sleep(2)  

def bye():
    while count < 5:
        incre()

def hello_there():
    while count < 5:
        incre()

def main():    
    hello = Thread(hello_there)
    goodbye = Thread(bye)


if __name__ == '__main__':
    main()

Sample output:

...
Inside hello_there()
Acquiring lock
Lock Acquired
Inside bye()
Acquiring lock
Lock Acquired
...

Something like this should suffice, to do what your batch file was doing (dumping the result set as semi-colon delimited text to the console):

// sqlcmd.exe
// -S .\PDATA_SQLEXPRESS
// -U sa
// -P 2BeChanged!
// -d PDATA_SQLEXPRESS
// -s ; -W -w 100
// -Q "SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName, tPatDBirthday  FROM  [dbo].[TPatientRaw] WHERE tPatSName = '%name%' "

DataTable dt            = new DataTable() ;
int       rows_returned ;

const string credentials = @"Server=(localdb)\.\PDATA_SQLEXPRESS;Database=PDATA_SQLEXPRESS;User ID=sa;Password=2BeChanged!;" ;
const string sqlQuery = @"
  select tPatCulIntPatIDPk ,
         tPatSFirstname    ,
         tPatSName         ,
         tPatDBirthday
  from dbo.TPatientRaw
  where tPatSName = @patientSurname
  " ;

using ( SqlConnection connection = new SqlConnection(credentials) )
using ( SqlCommand    cmd        = connection.CreateCommand() )
using ( SqlDataAdapter sda       = new SqlDataAdapter( cmd ) )
{
  cmd.CommandText = sqlQuery ;
  cmd.CommandType = CommandType.Text ;
  connection.Open() ;
  rows_returned = sda.Fill(dt) ;
  connection.Close() ;
}

if ( dt.Rows.Count == 0 )
{
  // query returned no rows
}
else
{

  //write semicolon-delimited header
  string[] columnNames = dt.Columns
                           .Cast<DataColumn>()
                           .Select( c => c.ColumnName )
                           .ToArray()
                           ;
  string   header      = string.Join("," , columnNames) ;
  Console.WriteLine(header) ;

  // write each row
  foreach ( DataRow dr in dt.Rows )
  {

    // get each rows columns as a string (casting null into the nil (empty) string
    string[] values = new string[dt.Columns.Count];
    for ( int i = 0 ; i < dt.Columns.Count ; ++i )
    {
      values[i] = ((string) dr[i]) ?? "" ; // we'll treat nulls as the nil string for the nonce
    }

    // construct the string to be dumped, quoting each value and doubling any embedded quotes.
    string data = string.Join( ";" , values.Select( s => "\""+s.Replace("\"","\"\"")+"\"") ) ;
    Console.WriteLine(values);

  }

}

Hope this helps :)

begins the session, you need to say this at the top of a page or before you call session code

 session_start(); 

put a user id in the session to track who is logged in

 $_SESSION['user'] = $user_id;

Check if someone is logged in

 if (isset($_SESSION['user'])) {
   // logged in
 } else {
   // not logged in
 }

Find the logged in user ID

$_SESSION['user']

So on your page

 <?php
 session_start();


 if (isset($_SESSION['user'])) {
 ?>
   logged in HTML and code here
 <?php

 } else {
   ?>
   Not logged in HTML and code here
   <?php
 }

I had much issues with this one too. I finally found out what's the final deal.

Referring to @Gokhan Oner answer, once you've got your Service class and the POJO representing your object, your YAML config file nice and lean, if you use the annotation @ConfigurationProperties, you have to explicitly get the object for being able to use it. Like :

@ConfigurationProperties(prefix = "available-payment-channels-list")
//@Configuration  <-  you don't specificly need this, instead you're doing something else
public class AvailableChannelsConfiguration {

    private String xyz;
    //initialize arraylist
    private List<ChannelConfiguration> channelConfigurations = new ArrayList<>();

    public AvailableChannelsConfiguration() {
        for(ChannelConfiguration current : this.getChannelConfigurations()) {
            System.out.println(current.getName()); //TADAAA
        }
    }

    public List<ChannelConfiguration> getChannelConfigurations() {
        return this.channelConfigurations;
    }

    public static class ChannelConfiguration {
        private String name;
        private String companyBankAccount;
    }

}

And then here you go. It's simple as hell, but we have to know that we must call the object getter. I was waiting at initialization, wishing the object was being built with the value but no. Hope it helps :)

Try this

 <input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden">

This has been possible since the queryset-refactor branch landed pre-1.0. Ticket 4088 exposed the problem. This should work:

Asset.objects.filter(
    desc__contains=filter,
    project__name__contains="Foo").order_by("desc")

The Django Many-to-one documentation has this and other examples of following Foreign Keys using the Model API.

Just some additions to previous answers. There are aliases defined for Get-Content, for example if you are used to UNIX you might like cat, and there are also type and gc. So instead of

Get-Content -Path <Path> -Wait -Tail 10

you can write

# Print whole file and wait for appended lines and print them
cat <Path> -Wait
# Print last 10 lines and wait for appended lines and print them
cat <Path> -Tail 10 -Wait

Use ROUND but with num_digits = -1

=ROUND(A1,-1)

Also applies to ROUNDUP and ROUNDDOWN

From Excel help:

• If num_digits is greater than 0 (zero), then number is rounded to the specified number of decimal places.
• If num_digits is 0, then number is rounded to the nearest integer.
• If num_digits is less than 0, then number is rounded to the left of the decimal point.

EDIT: To get the numbers to always round up use =ROUNDUP(A1,-1)

I had a dir full of files including some that were named invoice no-product no.pdf and wanted to sort these by product no, so...

get-childitem *.pdf | sort-object -property @{expression={$\_.name.substring($\_.name.indexof("-")+1)}}

Note that in the absence of a - this sorts by $_.name

Kotlin version of using LocalBroadcastManager:

Please check the below code for registering, sending and receiving the broadcast message.

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // register broadcast manager
        val localBroadcastManager = LocalBroadcastManager.getInstance(this)
        localBroadcastManager.registerReceiver(receiver, IntentFilter("your_action"))
    }

    // broadcast receiver
    var receiver: BroadcastReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent?) {
            if (intent != null) {
                val str = intent.getStringExtra("key")
                
            }
        }
    }

    /**
     * Send broadcast method
     */
    fun sendBroadcast() {
        val intent = Intent("your_action")
        intent.putExtra("key", "Your data")
        LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
    }

    override fun onDestroy() {
        // Unregister broadcast
        LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver)
        super.onDestroy()
    }

}

Or you can encapsulate the looping logic itself in a try catch e.g.

for(int i = function2(); i < 100 /*where 100 is the end or another function call to get the end*/; i = function2()){

    try{
     //ToDo
    }
    catch { continue; }    

}

Or...

try{ 
    for(int i = function2(); ; ;) {
        try { i = function2(); return; } 
        finally { /*decide to break or not :P*/continue; } }
} catch { /*failed on first try*/ } finally{ /*afterwardz*/ }

Unless you have sudo permissions to change it or its in your own usergroup/account you will not be able to get into it.

Check out man chmod in the terminal for more information about changing permissions of a directory.

You can just convert everything to lowercase for the purposes of sorting:

SELECT * FROM NOTES ORDER BY LOWER(title);

If you want to make sure that the uppercase ones still end up ahead of the lowercase ones, just add that as a secondary sort:

SELECT * FROM NOTES ORDER BY LOWER(title), title;

Turns out that it happened because of the firewall on my computer. Turning it off worked for me.

Found a nice solution by Laurent Bugnion, it can look something like this:

<UserControl xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:comment="Tag to add comments"
             mc:Ignorable="d comment" d:DesignHeight="300" d:DesignWidth="300">
    <Grid>
        <Button Width="100"
                comment:Width="example comment on Width, will be ignored......">
        </Button>
    </Grid>
</UserControl>

Here's the link: http://blog.galasoft.ch/posts/2010/02/quick-tip-commenting-out-properties-in-xaml/

A commenter on the link provided extra characters for the ignore prefix in lieu of highlighting:

mc:Ignorable=”ØignoreØ”

As RedBlueThing and analog said:

• dir() gives a list of in scope variables
• globals() gives a dictionary of global variables
• locals() gives a dictionary of local variables

Using the interactive shell (version 2.6.9), after creating variables a = 1 and b = 2, running dir() gives

['__builtins__', '__doc__', '__name__', '__package__', 'a', 'b']

running locals() gives

{'a': 1, 'b': 2, '__builtins__': <module '__builtin__' (built-in)>, '__package__': None, '__name__': '__main__', '__doc__': None}

Running globals() gives exactly the same answer as locals() in this case.

I haven't gotten into any modules, so all the variables are available as both local and global variables. locals() and globals() list the values of the variables as well as the names; dir() only lists the names.

If I import a module and run locals() or globals() inside the module, dir() still gives only a small number of variables; it adds __file__ to the variables listed above. locals() and globals() also list the same variables, but in the process of printing out the dictionary value for __builtin__, it lists a far larger number of variables: built-in functions, exceptions, and types such as "'type': <type 'type'>", rather than just the brief <module '__builtin__' (built-in)> as shown above.

For more about dir() see Python 2.7 quick reference at New Mexico Tech or the dir() function at ibiblio.org.

For more about locals() and globals() see locals and globals at Dive Into Python and a page about globals at New Mexico Tech.

[Comment: @Kurt: You gave a link to enumerate-or-list-all-variables-in-a-program-of-your-favorite-language-here but that answer has a mistake in it. The problem there is: type(name) in that example will always return <type 'str'>. You do get a list of the variables, which answers the question, but with incorrect types listed beside them. This was not obvious in your example because all the variables happened to be strings anyway; however, what it's returning is the type of the name of the variable instead of the type of the variable. To fix this: instead of print type(name) use print eval('type(' + name + ')'). I apologize for posting a comment in the answer section but I don't have comment posting privileges, and the other question is closed.]

The -k option is what you want.

-k 1.4,1.5n -k 1.14,1.15n

Would use character positions 4-5 in the first field (it's all one field for fixed width) and sort numerically as the first key.

The second key would be characters 14-15 in the first field also.

(edit)

Example (all I have is DOS/cygwin handy):

dir | \cygwin\bin\sort.exe -k 1.4,1.5n -k 1.40,1.60r

for the data:

Sorts the directory listing by month number (pos 4-5) numerically, and then by filename (pos 40-60) in reverse. Since there are no tabs, it's all field 1 to sort.

$fname = "database.php";
$fhandle = fopen($fname,"r");
$content = fread($fhandle,filesize($fname));
$content = str_replace("192.168.1.198", "localhost", $content);

$fhandle = fopen($fname,"w");
fwrite($fhandle,$content);
fclose($fhandle);

For the primitive types, the 'final static' will be a proper declaration to declare a constant. A non-static final variable makes sense when it is a constant reference to an object. In this case each instance can contain its own reference, as shown in JLS 4.5.4.

See Pavel's response for the correct answer.

This doesn't sound intuitive but select the column you're having the issue with and use "text to column" and just press finish. This is the suggested answer from Excel help as well. For some reason in converts text to numbers.

Just leaving the way using Microsoft.AspNet.WebApi.Client here.

Example:

var client = HttpClientFactory.Create();
var result = await client.PostAsync<ExampleClass>("http://www.sample.com/write", new ExampleClass(), new JsonMediaTypeFormatter());

Here's what finally worked for me. You'll have to convert the code to suit your own needs, but this will do it.

$fname = filter_input(INPUT_POST, "name");
$img = filter_input(INPUT_POST, "image");
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$img = base64_decode($img);

file_put_contents($fname, $img);

print "Image has been saved!";

Some additional advice for Windows(10) users:

1. If you are using Anaconda Prompt/PowerShell for the first time, type "Anaconda" in the search field of your Windows task bar and you will see the suggested software.
2. Make sure to open the Anaconda prompt as administrator.
3. Always navigate to your user directory or the directory with your Jupyter Notebook files first before running the command. Otherwise you might end up somewhere in your system files and be confused by an unfamiliar file tree.

The correct way to open Jupyter notebook with new data limit from the Anaconda Prompt on my own Windows 10 PC is:

(base) C:\Users\mobarget\Google Drive\Jupyter Notebook>jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

add a repository,

sudo apt-add-repository ppa:maarten-fonville/android-studio
sudo apt-get update

Then install using the command below:

sudo apt-get install android-studio

You could also try to run the following command:

devenv /ResetSkipPkgs

I second NLog too because it works with unmanaged code too. I suppose it could be possibe to use log4net and log4cxx together, but NLog handles both managed and unmanaged code out of the box.

I also looked at Common.Logging, a facade that makes abstraction of the logging api, it supports log4net, NLog and Entreprise Library. I don't think i'll use it, but i like how they use lambdas to improve performance when logging is disabled (a feature shared with NLog and probably others).

You are using RxJS 6. Just replace

import { Observable } from 'rxjs/Observable';
import { of } from 'rxjs/observable/of';

by

import { Observable, of } from 'rxjs';

In line 2, there's a std::string involved (name). There are operations defined for char[] + std::string, std::string + char[], etc. "Hello " + name gives a std::string, which is added to " you are ", giving another string, etc.

In line 3, you're saying

char[] + char[] + char[]

and you can't just add arrays to each other.

The below code helps, if you use Gradle. Allows you to easily remove unneeded Google services (presuming you're using them) to get back below the 65k threshold. All credit to this post: https://gist.github.com/dmarcato/d7c91b94214acd936e42

Edit 2014-10-22: There's been a lot of interesting discussion on the gist referenced above. TLDR? look at this one: https://gist.github.com/Takhion/10a37046b9e6d259bb31

Paste this code at the bottom of your build.gradle file and adjust the list of google services you do not need:

def toCamelCase(String string) {
    String result = ""
    string.findAll("[^\\W]+") { String word ->
        result += word.capitalize()
    }
    return result
}

afterEvaluate { project ->
    Configuration runtimeConfiguration = project.configurations.getByName('compile')
    ResolutionResult resolution = runtimeConfiguration.incoming.resolutionResult
    // Forces resolve of configuration
    ModuleVersionIdentifier module = resolution.getAllComponents().find { it.moduleVersion.name.equals("play-services") }.moduleVersion

    String prepareTaskName = "prepare${toCamelCase("${module.group} ${module.name} ${module.version}")}Library"
    File playServiceRootFolder = project.tasks.find { it.name.equals(prepareTaskName) }.explodedDir

    Task stripPlayServices = project.tasks.create(name: 'stripPlayServices', group: "Strip") {
        inputs.files new File(playServiceRootFolder, "classes.jar")
        outputs.dir playServiceRootFolder
        description 'Strip useless packages from Google Play Services library to avoid reaching dex limit'

        doLast {
            copy {
                from(file(new File(playServiceRootFolder, "classes.jar")))
                into(file(playServiceRootFolder))
                rename { fileName ->
                    fileName = "classes_orig.jar"
                }
            }
            tasks.create(name: "stripPlayServices" + module.version, type: Jar) {
                destinationDir = playServiceRootFolder
                archiveName = "classes.jar"
                from(zipTree(new File(playServiceRootFolder, "classes_orig.jar"))) {
                    exclude "com/google/ads/**"
                    exclude "com/google/android/gms/analytics/**"
                    exclude "com/google/android/gms/games/**"

                    exclude "com/google/android/gms/ads/**"
                }
            }.execute()
            delete file(new File(playServiceRootFolder, "classes_orig.jar"))
        }
    }

    project.tasks.findAll { it.name.startsWith('prepare') && it.name.endsWith('Dependencies') }.each { Task task ->
        task.dependsOn stripPlayServices
    }
}

Windows has a concept of current directory for each drive. Because of that, "c:sourcedir" means "sourcedir" inside the current C: directory, and you'll need to specify an absolute directory.

Any of these should work and give the same result, but I don't have a Windows VM fired up at the moment to double check:

"c:/sourcedir"
os.path.join("/", "c:", "sourcedir")
os.path.join("c:/", "sourcedir")

In my case, this error was due to special characters what I was considering double quotes as I copied the command from a web page.

In case you don't want (or have) a running container, you can call your script directly with the run command.

Remove the iterative tty -i -t arguments and use this:

    $ docker run ubuntu:bionic /bin/bash /path/to/script.sh

This will (didn't test) also work for other scripts:

    $ docker run ubuntu:bionic /usr/bin/python /path/to/script.py

I use SourceTree git client, and I see that their initial commit/push command is:

git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags --set-upstream origin master:master

if you have a checkbox and you would like to fetch it's value ie true / false in any java file--

Use--

Context mContext;
boolean checkFlag;

checkFlag=PreferenceManager.getDefaultSharedPreferences(mContext).getBoolean(KEY,DEFAULT_VALUE);`

Inside of a for-loop block, you can access some special variables including loop.index --but no loop.counter. From the official docs:

Variable    Description
loop.index  The current iteration of the loop. (1 indexed)
loop.index0 The current iteration of the loop. (0 indexed)
loop.revindex   The number of iterations from the end of the loop (1 indexed)
loop.revindex0  The number of iterations from the end of the loop (0 indexed)
loop.first  True if first iteration.
loop.last   True if last iteration.
loop.length The number of items in the sequence.
loop.cycle  A helper function to cycle between a list of sequences. See the explanation below.
loop.depth  Indicates how deep in a recursive loop the rendering currently is. Starts at level 1
loop.depth0 Indicates how deep in a recursive loop the rendering currently is. Starts at level 0
loop.previtem   The item from the previous iteration of the loop. Undefined during the first iteration.
loop.nextitem   The item from the following iteration of the loop. Undefined during the last iteration.
loop.changed(*val)  True if previously called with a different value (or not called at all).

This worked for me git describe --tags --abbrev=0

Edit 2020: As mentioned by some of the comments below, this might, or might not work for you, so be careful!

I was trying to download zip files linked from Omeka's themes page - pretty similar task. This worked for me:

wget -A zip -r -l 1 -nd http://omeka.org/add-ons/themes/

• -A: only accept zip files
• -r: recurse
• -l 1: one level deep (ie, only files directly linked from this page)
• -nd: don't create a directory structure, just download all the files into this directory.

All the answers with -k, -K, -E etc options probably haven't really understood the question, as those as for rewriting HTML pages to make a local structure, renaming .php files and so on. Not relevant.

To literally get all files except .html etc:

wget -R html,htm,php,asp,jsp,js,py,css -r -l 1 -nd http://yoursite.com

toInteger() method is available in groovy, you could use that.

In case anyone wishes to do this with bootstrap, version 4 offers the following:

The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

Where property is one of:

m - for classes that set margin
p - for classes that set padding

Where sides is one of:

t - for classes that set margin-top or padding-top
b - for classes that set margin-bottom or padding-bottom
l - for classes that set margin-left or padding-left
r - for classes that set margin-right or padding-right
x - for classes that set both *-left and *-right
y - for classes that set both *-top and *-bottom
blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

0 - for classes that eliminate the margin or padding by setting it to 0
1 - (by default) for classes that set the margin or padding to $spacer * .25
2 - (by default) for classes that set the margin or padding to $spacer * .5
3 - (by default) for classes that set the margin or padding to $spacer
4 - (by default) for classes that set the margin or padding to $spacer * 1.5
5 - (by default) for classes that set the margin or padding to $spacer * 3
auto - for classes that set the margin to auto

For example:

.mt-0 {
  margin-top: 0 !important;
}

.ml-1 {
  margin-left: ($spacer * .25) !important;
}

.px-2 {
  padding-left: ($spacer * .5) !important;
  padding-right: ($spacer * .5) !important;
}

.p-3 {
  padding: $spacer !important;
}

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

You can use rows and cols:

cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;

or size():

cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;

Aside from personal design preferences, there are cases where one wants to make use of composite primary keys. Tables may have two or more fields that provide a unique combination, and not necessarily by way of foreign keys.

As an example, each US state has a set of unique Congressional districts. While many states may individually have a CD-5, there will never be more than one CD-5 in any of the 50 states, and vice versa. Therefore, creating an autonumber field for Massachusetts CD-5 would be redundant.

If the database drives a dynamic web page, writing code to query on a two-field combination could be much simpler than extracting/resubmitting an autonumbered key.

So while I'm not answering the original question, I certainly appreciate Adam's direct answer.

I had the same problem which was mainly due to an update to PyQt5, the following code helped me.

Run cmd.exe as admin:

conda update conda
conda update anaconda-navigator

reinstall PyQt5:

pip uninstall PyQt5
pip install PyQt5
pip install pyqtwebengine 

In your Info.plist, Right click in the properties table, click Add Row, add key name App Uses Non-Exempt Encryption with Type Boolean and set value NO.

Actually you dont need to call document.getElementById() function to get access to your div.

You can use this object directly by id:

text = test.textContent || test.innerText;
alert(text);

It has already been explained that calling system.gc() may do nothing, and that any code that "needs" the garbage collector to run is broken.

However, the pragmatic reason that it is bad practice to call System.gc() is that it is inefficient. And in the worst case, it is horribly inefficient! Let me explain.

A typical GC algorithm identifies garbage by traversing all non-garbage objects in the heap, and inferring that any object not visited must be garbage. From this, we can model the total work of a garbage collection consists of one part that is proportional to the amount of live data, and another part that is proportional to the amount of garbage; i.e. work = (live * W1 + garbage * W2).

Now suppose that you do the following in a single-threaded application.

System.gc(); System.gc();

The first call will (we predict) do (live * W1 + garbage * W2) work, and get rid of the outstanding garbage.

The second call will do (live* W1 + 0 * W2) work and reclaim nothing. In other words we have done (live * W1) work and achieved absolutely nothing.

We can model the efficiency of the collector as the amount of work needed to collect a unit of garbage; i.e. efficiency = (live * W1 + garbage * W2) / garbage. So to make the GC as efficient as possible, we need to maximize the value of garbage when we run the GC; i.e. wait until the heap is full. (And also, make the heap as big as possible. But that is a separate topic.)

If the application does not interfere (by calling System.gc()), the GC will wait until the heap is full before running, resulting in efficient collection of garbage¹. But if the application forces the GC to run, the chances are that the heap won't be full, and the result will be that garbage is collected inefficiently. And the more often the application forces GC, the more inefficient the GC becomes.

Note: the above explanation glosses over the fact that a typical modern GC partitions the heap into "spaces", the GC may dynamically expand the heap, the application's working set of non-garbage objects may vary and so on. Even so, the same basic principal applies across the board to all true garbage collectors². It is inefficient to force the GC to run.

^{1 - This is how the "throughput" collector works. Concurrent collectors such as CMS and G1 use different criteria to decide when to start the garbage collector.}

^{2 - I'm also excluding memory managers that use reference counting exclusively, but no current Java implementation uses that approach ... for good reason.}

Using set and the /p parameter you can echo without newline:

C:\> echo Hello World
Hello World

C:\> echo|set /p="Hello World"

The WSDL is a kind of contract between API provider and the client it's describe the web service : the public function , optional/required field ...

But The soap message is a data transferred between client and provider (payload)

in linux/ubuntu you can do, run following commands

cd ~/.config/JetBrains/PyCharm2020.1
rm eval/PyCharm201.evaluation.key
sed -i '/evlsprt/d' options/other.xml
cd ~/.java/.userPrefs/jetbrains
rm -rf pycharm*

Consider:

if(rsData.Read()) {
  int index = rsData.GetOrdinal("columnName"); // I expect, just "ursrdaystime"
  if(rsData.IsDBNull(index)) {
     // is a null
  } else {
     // access the value via any of the rsData.Get*(index) methods
  }
} else {
  // no row returned
}

Also: you need more using ;p

'thirsty me making are pretzels These'

Yep, saw this (and many more), even implemented it in a test application. Really need to get the definitive word from Apple, but the community consensus opinion is Apple disallowed it in 5.1 after it was publicly "discovered/published", so applications containing it won't be accepted.

08/01/12 Update: Asked Apple through my developer account if there is a way to programmatically launch the WiFi Settings dialog. Here is the response:

"Our engineers have reviewed your request and have concluded that there is no supported way to achieve the desired functionality given the currently shipping system configurations."

For those on OSX, I used the following binary to get libpng and libjpeg installed systemwide:

libpng & libjpeg for OSX

Because I already had PIL installed (via pip on a virtualenv), I ran:

pip uninstall PIL
pip install PIL --upgrade

This resolved the decoder JPEG not available error for me.

UPDATE (4/24/14):

Newer versions of pip require additional flags to download libraries (including PIL) from external sources. Try the following:

pip install PIL --allow-external PIL --allow-unverified PIL

See the following answer for additional info: pip install PIL dont install into virtualenv

UPDATE 2:

If on OSX Mavericks, you'll want to set the ARCHFLAGS flag as @RicardoGonzales comments below:

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install PIL --allow-external PIL --allow-unverified PIL

I had similar problem (in bash terminal command was working correctly but zsh showed command not found error)

Solution:

just paste whatever you were earlier pasting in ~/.bashrc to:

~/.zshrc

say you define the static getFactorial function inside a CodeController

then this is the way you need to call a static function, because static properties and methods exists with in the class, not in the objects created using the class.

CodeController::getFactorial($index);

----------------UPDATE----------------

To best practice I think you can put this kind of functions inside a separate file so you can maintain with more easily.

to do that

create a folder inside app directory and name it as lib (you can put a name you like).

this folder to needs to be autoload to do that add app/lib to composer.json as below. and run the composer dumpautoload command.

"autoload": {
    "classmap": [
                "app/commands",
                "app/controllers",
                ............
                "app/lib"
    ]
},

then files inside lib will autoloaded.

then create a file inside lib, i name it helperFunctions.php

inside that define the function.

if ( ! function_exists('getFactorial'))
{

    /**
     * return the factorial of a number
     *
     * @param $number
     * @return string
     */
    function getFactorial($date)
    {
        $fact = 1;

        for($i = 1; $i <= $num ;$i++)
            $fact = $fact * $i;

        return $fact;

     }
}

and call it anywhere within the app as

$fatorial_value = getFactorial(225);

Description

There are many ways to validate your TextBox. You can do this on every keystroke, at a later time, or on the Validating event.

The Validating event gets fired if your TextBox looses focus. When the user clicks on a other Control, for example. If your set e.Cancel = true the TextBox doesn't lose the focus.

MSDN - Control.Validating Event When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), by calling the Select or SelectNextControl methods, or by setting the ContainerControl.ActiveControl property to the current form, focus events occur in the following order

Enter

GotFocus

Leave

Validating

Validated

LostFocus

When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:

Enter

GotFocus

LostFocus

Leave

Validating

Validated

Sample Validating Event

private void textBox1_Validating(object sender, CancelEventArgs e)
{
    if (textBox1.Text != "something")
        e.Cancel = true;
}

Update

You can use the ErrorProvider to visualize that your TextBox is not valid. Check out Using Error Provider Control in Windows Forms and C#

This answer outlines two ways to workaround APIs that don't support CORS:

• Use a CORS Proxy
• Use JSONP if the API Supports it

One workaround is to use a CORS PROXY:

angular.module("app",[])
.run(function($rootScope,$http) { 
     var proxy = "//cors-anywhere.herokuapp.com";
     var url = "http://api.ipify.org/?format=json";
     $http.get(proxy +'/'+ url)
       .then(function(response) {
         $rootScope.response = response.data;
     }).catch(function(response) {
         $rootScope.response = 'ERROR: ' + response.status;
     })     
})

<script src="//unpkg.com/angular/angular.js"></script>
<body ng-app="app">
   Response = {{response}}
</body>

For more information, see

• GitHub: CORS Anywhere

Use JSONP if the API supports it:

 var url = "//api.ipify.org/";
 var trust = $sce.trustAsResourceUrl(url);
 $http.jsonp(trust,{params: {format:'jsonp'}})
   .then(function(response) {
     console.log(response);
     $scope.response = response.data;
 }).catch(function(response) {
     console.log(response);
     $scope.response = 'ERROR: ' + response.status;
 })

Here is an input box with a search icon on the right.

  <div class="input-group">
      <input class="form-control py-2 border-right-0 border" type="search" placeholder="Search">
      <div class="input-group-append">
          <div class="input-group-text" id="btnGroupAddon2"><i class="fa fa-search"></i></div>
      </div>
  </div>

Here is an input box with a search icon on the left.

  <div class="input-group">
      <div class="input-group-prepend">
          <div class="input-group-text" id="btnGroupAddon2"><i class="fa fa-search"></i></div>
      </div>
      <input class="form-control py-2 border-right-0 border" type="search" placeholder="Search">
  </div>

Here is another way of solving this:

df1[~df1.index.isin(df1.merge(df2, how='inner', on=['col1', 'col2']).index)]

Or:

df1.loc[df1.index.difference(df1.merge(df2, how='inner', on=['col1', 'col2']).index)]

in my case: invalidateOptionsMenu just re-setted the text to the original one, but directly accessing the menu item and re-writing the desire text worked without problems:

if (mnuTopMenuActionBar_ != null) {
    MenuItem mnuPageIndex = mnuTopMenuActionBar_
        .findItem(R.id.menu_magazin_pageOfPage_text);

    if (mnuPageIndex != null) {
        if (getScreenOrientation() == 1) {
            mnuPageIndex.setTitle((i + 1) + " von " + pages);
        }
        else {
            mnuPageIndex.setTitle(
                (i + 1) + " + " + (i + 2) + " " + " von " + pages);
        }
        // invalidateOptionsMenu();
    }
}

due to the comment below, I was able to access the menu item via the following code:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.magazine_swipe_activity, menu);
    mnuTopMenuActionBar_ = menu;
    return true;
}

DateFormat.format only works on Date values.

You should use two SimpleDateFormat objects: one for parsing, and one for formatting. For example:

// Note, MM is months, not mm
DateFormat outputFormat = new SimpleDateFormat("MM/yyyy", Locale.US);
DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX", Locale.US);

String inputText = "2012-11-17T00:00:00.000-05:00";
Date date = inputFormat.parse(inputText);
String outputText = outputFormat.format(date);

EDIT: Note that you may well want to specify the time zone and/or locale in your formats, and you should also consider using Joda Time instead of all of this to start with - it's a much better date/time API.

I'll provide a simple Server Side Real World Example here, say if the records are looped and each record has a form with a delete button and you need to delete a specific record, so here comes the hidden field in action, else you won't get the reference of the record to be deleted in this case, it will be id

For example

<?php
    if(isset($_POST['delete_action'])) {
        mysqli_query($connection, "DELETE FROM table_name 
                                   WHERE record_id = ".$_POST['row_to_be_deleted']);
                                   //Here is where hidden field value is used
    }

    while(condition) {
?>
    <span><?php echo 'Looped Record Name'; ?>
    <form method="post">
        <input type="hidden" name="row_to_be_deleted" value="<?php echo $record_id; ?>" />
        <input type="submit" name="delete_action" />
    </form>
<?php
    }
?>

Use:

#include <windows.h>

Sleep(sometime_in_millisecs); // Note uppercase S

And here's a small example that compiles with MinGW and does what it says on the tin:

#include <windows.h>
#include <stdio.h>

int main() {
    printf( "starting to sleep...\n" );
    Sleep(3000); // Sleep three seconds
    printf("sleep ended\n");
}

in HQL you can use query parameter and set Collection with setParameterList method.

    Query q = session.createQuery("SELECT entity FROM Entity entity WHERE name IN (:names)");
    q.setParameterList("names", names);

An alternative approach is resample, which can handle duplicate dates in addition to missing dates. For example:

df.resample('D').mean()

resample is a deferred operation like groupby so you need to follow it with another operation. In this case mean works well, but you can also use many other pandas methods like max, sum, etc.

Here is the original data, but with an extra entry for '2013-09-03':

             val
date           
2013-09-02     2
2013-09-03    10
2013-09-03    20    <- duplicate date added to OP's data
2013-09-06     5
2013-09-07     1

And here are the results:

             val
date            
2013-09-02   2.0
2013-09-03  15.0    <- mean of original values for 2013-09-03
2013-09-04   NaN    <- NaN b/c date not present in orig
2013-09-05   NaN    <- NaN b/c date not present in orig
2013-09-06   5.0
2013-09-07   1.0

I left the missing dates as NaNs to make it clear how this works, but you can add fillna(0) to replace NaNs with zeroes as requested by the OP or alternatively use something like interpolate() to fill with non-zero values based on the neighboring rows.

I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application

Excerpt from the linked page:

Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:

Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.

Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the Include method.

Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace Collection(x => x.Courses) with Reference(x => x.Administrator).) Typically you'd use explicit loading only when you've turned lazy loading off.

Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.

This solution is from Beginning Hibernate book:

     Query<User> query = session.createQuery("from User u where u.scn=:scn", User.class);
     query.setParameter("scn", scn);
     User user = query.uniqueResult();    

os.Mkdir is used to create a single directory. To create a folder path, instead try using:

os.MkdirAll(folderPath, os.ModePerm)

Go documentation

func MkdirAll(path string, perm FileMode) error

MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error. The permission bits perm are used for all directories that MkdirAll creates. If path is already a directory, MkdirAll does nothing and returns nil.

Edit:

Updated to correctly use os.ModePerm instead.
For concatenation of file paths, use package path/filepath as described in @Chris' answer.

Try this code working fine check codeigniter version

Just go to 'system' > 'core' > 'CodeIgniter.php' and look for the lines,

/**
 * CodeIgniter Version
 *
 * @var    string
 *
 */
    define('CI_VERSION', '3.0.0');

Alternate method to check codeigniter version, you can echo the constant value 'CI_VERSION' somewhere in codeigniter controller/view file.

<?php
    echo CI_VERSION;
?>

Try shutil.rmtree:

import shutil
shutil.rmtree('/path/to/your/dir/')

it is depends on requirement , but many developers suggestions is to make your code as simple as possible . so, go with simple "hr" tag and CSS code for that.

The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.

To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.

Could I write "table" or any other html tag instead of "/" ?

Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.

Here a few links:

• XSL templates
• XPath
• A good book about XML - Beginning XML

I just wanted to illustrate that the built-in solutions (SQL-only) are not always the best ones. At first I thought that because Django's QuerySet.objects.order_by method accepts multiple arguments, you could easily chain them:

ordered_authors = Author.objects.order_by('-score', 'last_name')[:30]

But, it does not work as you would expect. Case in point, first is a list of presidents sorted by score (selecting top 5 for easier reading):

>>> auths = Author.objects.order_by('-score')[:5]
>>> for x in auths: print x
... 
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)

Using Alex Martelli's solution which accurately provides the top 5 people sorted by last_name:

>>> for x in sorted(auths, key=operator.attrgetter('last_name')): print x
... 
Benjamin Harrison (467)
James Monroe (487)
Gerald Rudolph (464)
Ulysses Simpson (474)
Harry Truman (471)

And now the combined order_by call:

>>> myauths = Author.objects.order_by('-score', 'last_name')[:5]
>>> for x in myauths: print x
... 
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)

As you can see it is the same result as the first one, meaning it doesn't work as you would expect.

An other solution:

interface bar {
    length: number;
}

bars = [{
  length: 1
} as bar];
