The filter option filters only the first level subkey below ansible_facts

That's where constructors come into play. If you have a default constructor (eg. with no parameters) that always creates a new Map, then you're sure that every instance of this class will always have an already instantiated Map.

If you are sure you haven't messed the jar, then please clean the project and perform mvn clean install. This should solve the problem.

If you want it to "stick" to the bottom, regardless of the height of container, then absolute positioning is the way to go. Of course, if the copyright element is the last in the container it'll always be at the bottom anyway.

Can you expand on your question? Explain exactly what you're trying to do (and why you don't want to use absolute positioning)?

In Visual Studio 2015 (Soulution is under source control, MVC-Project), csano's Update-Package -Reinstall -ProjectName Your.Project.Name worked, but it messed up with some write locks.

I had to delete the "packages"-Folder manually before. (It seemed to be locked because of the source control).

Also, I had to re-install the MVC-Package from the NuGet Package Manager.

How can I accomplish that?

Your example declares a TypeScript < 1.5 internal module, which is now called a namespace. The old module App {} syntax is now equivalent to namespace App {}. As a result, the following works:

// test.ts
export namespace App {
    export class SomeClass {
        getName(): string {
            return 'name';
        }
    }
}

// main.ts
import { App } from './test';
var a = new App.SomeClass();

That being said...

Try to avoid exporting namespaces and instead export modules (which were previously called external modules). If needs be you can use a namespace on import with the namespace import pattern like this:

// test.ts
export class SomeClass {
    getName(): string {
        return 'name';
    }
}

// main.ts
import * as App from './test'; // namespace import pattern
var a = new App.SomeClass();

I had the same problem with pip==1.5.6. I had to correct my system time.

go to kafka/libs folder we can see multiple jars search for something similar kafka_2.11-0.10.1.1.jar.asc in this case the kafka version is 0.10.1.1

<script type="text/javascript">
    document.write(document.referrer);
</script>

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

Daniel, awesome explanation! A couple of words on this and good list of this execution context pointer in case of event handlers.

In two words, this in JavaScript points the object from whom (or from whose execution context) the current function was run and it's always read-only, you can't set it anyway (such an attempt will end up with 'Invalid left-hand side in assignment' message.

For event handlers: inline event handlers, such as <element onclick="foo">, override any other handlers attached earlier and before, so be careful and it's better to stay off of inline event delegation at all. And thanks to Zara Alaverdyan who inspired me to this list of examples through a dissenting debate :)

• el.onclick = foo; // in the foo - obj
• el.onclick = function () {this.style.color = '#fff';} // obj
• el.onclick = function() {doSomething();} // In the doSomething - Window
• el.addEventListener('click',foo,false) // in the foo - obj
• el.attachEvent('onclick, function () { // this }') // window, all the compliance to IE :)
• <button onclick="this.style.color = '#fff';"> // obj
• <button onclick="foo"> // In the foo - window, but you can <button onclick="foo(this)">

Based on Fenton's answer, here's my implementation of a function to verify if a given object has the keys an interface has, both fully or partially.

Depending on your use case, you may also need to check the types of each of the interface's properties. The code below doesn't do that.

function implementsTKeys<T>(obj: any, keys: (keyof T)[]): obj is T {
    if (!obj || !Array.isArray(keys)) {
        return false;
    }

    const implementKeys = keys.reduce((impl, key) => impl && key in obj, true);

    return implementKeys;
}

Example of usage:

interface A {
    propOfA: string;
    methodOfA: Function;
}

let objectA: any = { propOfA: '' };

// Check if objectA partially implements A
let implementsA = implementsTKeys<A>(objectA, ['propOfA']);

console.log(implementsA); // true

objectA.methodOfA = () => true;

// Check if objectA fully implements A
implementsA = implementsTKeys<A>(objectA, ['propOfA', 'methodOfA']);

console.log(implementsA); // true

objectA = {};

// Check again if objectA fully implements A
implementsA = implementsTKeys<A>(objectA, ['propOfA', 'methodOfA']);

console.log(implementsA); // false, as objectA now is an empty object

With a few CSS overrides, I find the accordion / collapse plugin works well as a sidebar vertical menu. Here's a small sample of some overrides I use for a menu on a white background. The accordion is placed within a section container:

.accordion-group
{
    margin-bottom: 1px;
    -webkit-border-radius: 0px;
    -moz-border-radius: 0px;
    border-radius: 0px;
    border-bottom: 1px solid #E5E5E5;
    border-top: none;
    border-left: none;
    border-right: none;
}

.accordion-heading:hover
{
    background-color: #FFFAD9;
}

CREATE TABLE `admnih` (
  `id` int(255) NOT NULL auto_increment,
  `asim` varchar(255) NOT NULL default '',
  `brid` varchar(255) NOT NULL default '',
  `rwtbah` int(1) NOT NULL default '0',
  `esmmwkeh` varchar(255) NOT NULL default '',
  `mrwr` varchar(255) NOT NULL default '',
  `tid` int(255) NOT NULL default '0',
  `alksmfialdlil` int(255) NOT NULL default '0',
  `tariktsjil` varchar(255) NOT NULL default '',
  `aimwke` varchar(255) NOT NULL default '',
  `twkie` text NOT NULL,
  `rwtbahkasah` int(255) NOT NULL default '0',
  PRIMARY KEY  (`id`)
) TYPE=MyISAM AUTO_INCREMENT=2 ;

bash regular expression vs bash parameter expansion

As Charles Duffy's answer work, but only use bash regular expression, and I know this to be slow, I would like to show another way, using only bash parameter expansion:

For positive integers only:

is_num() { [ "$1" ] && [ -z "${1//[0-9]}" ] ;}

For integers:

is_num() { 
    local chk=${1#[+-]};
    [ "$chk" ] && [ -z "${chk//[0-9]}" ]
}

Then for floating:

is_num() { 
    local chk=${1#[+-]};
    chk=${chk/.}
    [ "$chk" ] && [ -z "${chk//[0-9]}" ]
}

To match initial request:

set -- "foo bar"
is_num "$1" && VAR=$1 || echo "need a number"
need a number

set -- "+3.141592"
is_num "$1" && VAR=$1 || echo "need a number"

echo $VAR
+3.141592

Now a little comparission:

There is a same check based on Charles Duffy's answer:

cdIs_num() { 
    local re='^[+-]?[0-9]+([.][0-9]+)?$';
    [[ $1 =~ $re ]]
}

Some tests:

if is_num foo;then echo It\'s a number ;else echo Not a number;fi
Not a number
if cdIs_num foo;then echo It\'s a number ;else echo Not a number;fi
Not a number
if is_num 25;then echo It\'s a number ;else echo Not a number;fi
It's a number
if cdIs_num 25;then echo It\'s a number ;else echo Not a number;fi
It's a number
if is_num 3+4;then echo It\'s a number ;else echo Not a number;fi
Not a number
if cdIs_num 3+4;then echo It\'s a number ;else echo Not a number;fi
Not a number
if is_num 3.1415;then echo It\'s a number ;else echo Not a number;fi
It's a number
if cdIs_num 3.1415;then echo It\'s a number ;else echo Not a number;fi
It's a number

Ok, that's fine. Now how many time will take all this (On my raspberry pi):

time for i in {1..1000};do is_num +3.14159265;done
real    0m2.476s
user    0m1.235s
sys     0m0.000s

Then with regular expressions:

time for i in {1..1000};do cdIs_num +3.14159265;done
real    0m4.363s
user    0m2.168s
sys     0m0.000s

They really should add a wrapper. Like this:

namespace std
{
    template<class _container,
        class _Ty> inline
        bool contains(_container _C, const _Ty& _Val)
        {return std::find(_C.begin(), _C.end(), _Val) != _C.end(); }
};
...
    if( std::contains(my_container, what_to_find) )
    {

    }

If you want to lookup/associate an object with a unique identifier without modifying the underlying object, you can use a WeakMap:

// Note that object must be an object or array,
// NOT a primitive value like string, number, etc.
var objIdMap=new WeakMap, objectCount = 0;
function objectId(object){
  if (!objIdMap.has(object)) objIdMap.set(object,++objectCount);
  return objIdMap.get(object);
}

var o1={}, o2={}, o3={a:1}, o4={a:1};
console.log( objectId(o1) ) // 1
console.log( objectId(o2) ) // 2
console.log( objectId(o1) ) // 1
console.log( objectId(o3) ) // 3
console.log( objectId(o4) ) // 4
console.log( objectId(o3) ) // 3

Using a WeakMap instead of Map ensures that the objects can still be garbage-collected.

You can just put:

header("HTTP/1.0 500 Internal Server Error");

inside your conditions like:

if (that happened) {
    header("HTTP/1.0 500 Internal Server Error");
}

As for the database query, you can just do that like this:

$result = mysql_query("..query string..") or header("HTTP/1.0 500 Internal Server Error");

You should remember that you have to put this code before any html tag (or output).

Class path entries can contain the basename wildcard character *, which is considered equivalent to specifying a list of all the files in the directory with the extension .jar or .JAR. For example, the class path entry foo/* specifies all JAR files in the directory named foo. A classpath entry consisting simply of * expands to a list of all the jar files in the current directory.

This should work in Java6, not sure about Java5

(If it seems it does not work as expected, try putting quotes. eg: "foo/*")

EDIT: Starting from IPython 3 (now Jupyter project), the notebook has a text editor that can be used as a more convenient alternative to load/edit/save text files.

A text file can be loaded in a notebook cell with the magic command %load.

If you execute a cell containing:

%load filename.py

the content of filename.py will be loaded in the next cell. You can edit and execute it as usual.

To save the cell content back into a file add the cell-magic %%writefile filename.py at the beginning of the cell and run it. Beware that if a file with the same name already exists it will be silently overwritten.

To see the help for any magic command add a ?: like %load? or %%writefile?.

For general help on magic functions type "%magic" For a list of the available magic functions, use %lsmagic. For a description of any of them, type %magic_name?, e.g. '%cd?'.

See also: Magic functions from the official IPython docs.

For shared libraries libNAME.so the -D switch was necessary to see symbols in my Linux

nm -D libNAME.so

and for static library as reported by others

nm -g libNAME.a

Android Studio is based on IntelliJ, and it comes with support for SVN (along with git and mercurial) bundled in. Check http://www.jetbrains.com/idea/features/version_control.html for more info.

You can use printf:

System.out.printf("string %c\n", 0x63);

You can as well create a String with such formatting, using String#format:

String s = String.format("string %c", 0x63);

Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.

It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.

If you're trying to take advantage of polymorphic behavior, you need to ensure that the methods visible to outside classes (that need polymorphism) have the same signature. That means they need to have the same name, number and order of parameters, as well as the parameter types.

In your case, you might do better to have a generic draw() method, and rely on the subclasses (Rectangle, Ellipse) to implement the draw() method as what you had been thinking of as "drawEllipse" and "drawRectangle".

I was trying to use aws-vault which uses pass and gnugp2 (gpg2). I'm on Ubuntu 20.04 running in WSL2.

I tried all the solutions above, and eventually, I had to do one more thing -

$ rm ~/.gnupg/S.*                    # remove cache
$ gpg-connect-agent reloadagent /bye # restart gpg agent
$ export GPG_TTY=$(tty)              # prompt for password
# ^ This last line should be added to your ~/.bashrc file

The source of this solution is from some blog-post in Japanese, luckily there's Google Translate :)

Here is an example. Imagine that you are going to put the files and directory names (under the current folder) to an array and count its items. The script would be like;

my_array=( `ls` )
my_array_length=${#my_array[@]}
echo $my_array_length

Or, you can iterate over this array by adding the following script:

for element in "${my_array[@]}"
do
   echo "${element}"
done

Please note that this is the core concept and the input is considered to be sanitized before, i.e. removing extra characters, handling empty Strings, and etc. (which is out of the topic of this thread).

Below code worked for me.

css

.parent{
    overflow: auto;
} 

html

<div class="parent">
    <div class="child1">
    </div>
    <div class="child2">
    </div>
    <div id="clear" style="clear:both;"></div>
</div>

You can use pd.to_datetime() to convert to a datetime object. It takes a format parameter, but in your case I don't think you need it.

>>> import pandas as pd
>>> df = pd.DataFrame( {'Symbol':['A','A','A'] ,
    'Date':['02/20/2015','01/15/2016','08/21/2015']})
>>> df
         Date Symbol
0  02/20/2015      A
1  01/15/2016      A
2  08/21/2015      A
>>> df['Date'] =pd.to_datetime(df.Date)
>>> df.sort('Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

For future search, you can change the sort statement:

>>> df.sort_values(by='Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

Simply change the text property

    TextField(
      controller: txt,
    ),
    RaisedButton(onPressed: () {
        txt.text = "My Stringt";
    }),

while txt is just a TextEditingController

  var txt = TextEditingController();

If you want to find versions prior to .NET 4.5, use code for a console application. Like this:

using System;
using System.Security.Permissions;
using Microsoft.Win32;

namespace findNetVersion
{
    class Program
    {
        static void Main(string[] args)
        {
            using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine,
                     RegistryView.Registry32).OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP\"))
            {
                foreach (string versionKeyName in ndpKey.GetSubKeyNames())
                {
                    if (versionKeyName.StartsWith("v"))
                    {

                        RegistryKey versionKey = ndpKey.OpenSubKey(versionKeyName);
                        string name = (string)versionKey.GetValue("Version", "");
                        string sp = versionKey.GetValue("SP", "").ToString();
                        string install = versionKey.GetValue("Install", "").ToString();
                        if (install == "") //no install info, must be later version
                            Console.WriteLine(versionKeyName + "  " + name);
                        else
                        {
                            if (sp != "" && install == "1")
                            {
                                Console.WriteLine(versionKeyName + "  " + name + "  SP" + sp);
                            }
                        }
                        if (name != "")
                        {
                            continue;
                        }
                        foreach (string subKeyName in versionKey.GetSubKeyNames())
                        {
                            RegistryKey subKey = versionKey.OpenSubKey(subKeyName);
                            name = (string)subKey.GetValue("Version", "");
                            if (name != "")
                                sp = subKey.GetValue("SP", "").ToString();
                                install = subKey.GetValue("Install", "").ToString();
                            if (install == "") //no install info, ust be later
                                Console.WriteLine(versionKeyName + "  " + name);
                            else
                            {
                                if (sp != "" && install == "1")
                                {
                                    Console.WriteLine("  " + subKeyName + "  " + name + "  SP" + sp);
                                }
                                else if (install == "1")
                                {
                                    Console.WriteLine("  " + subKeyName + "  " + name);
                                }
                            }
                        }
                    }
                }
            }
        }
    }
}

Otherwise you can find .NET 4.5 or later by querying like this:

private static void Get45or451FromRegistry()
{
    using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine,
       RegistryView.Registry32).OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\"))
    {
        int releaseKey = (int)ndpKey.GetValue("Release");
        {
            if (releaseKey == 378389)

                Console.WriteLine("The .NET Framework version 4.5 is installed");

            if (releaseKey == 378758)

                Console.WriteLine("The .NET Framework version 4.5.1  is installed");

        }
    }
}

Then the console result will tell you which versions are installed and available for use with your deployments. This code come in handy, too because you have them as saved solutions for anytime you want to check it in the future.

Wow so many answers yet none mentioned this Microsoft.EntityFrameworkCore.InMemory package!

Add the reference to this package: <PackageReference Include="Microsoft.EntityFrameworkCore.InMemory" Version="2.2.2" /> and you should be good to go.

I was struggling since a couple of hours for this issue because i was putting that file under resources folder but it didn't help me, finally i realized my mistake. Put it directly under src/main/java.

Tried the money trick above, and this works great for numerical values with two or less significant digits. I created my own function to format numbers with decimals:

CREATE FUNCTION [dbo].[fn_FormatWithCommas] 
(
    -- Add the parameters for the function here
    @value varchar(50)
)
RETURNS varchar(50)
AS
BEGIN
    -- Declare the return variable here
    DECLARE @WholeNumber varchar(50) = NULL, @Decimal varchar(10) = '', @CharIndex int = charindex('.', @value)

    IF (@CharIndex > 0)
        SELECT @WholeNumber = SUBSTRING(@value, 1, @CharIndex-1), @Decimal = SUBSTRING(@value, @CharIndex, LEN(@value))
    ELSE
        SET @WholeNumber = @value

    IF(LEN(@WholeNumber) > 3)
        SET @WholeNumber = dbo.fn_FormatWithCommas(SUBSTRING(@WholeNumber, 1, LEN(@WholeNumber)-3)) + ',' + RIGHT(@WholeNumber, 3)



    -- Return the result of the function
    RETURN @WholeNumber + @Decimal

END

To get the checked state of your checkbox the path would be:

this.refs.complete.state.checked

The alternative is to get it from the event passed into the handleChange method:

event.target.checked

            names = db.getSites();
            la = new ArrayAdapter<String>(EditSiteList.this,
                    android.R.layout.simple_list_item_1, names);
            EditSiteList.this.setListAdapter(la);
            listview.invalidateViews();

this code works fine for me.

Try this way it will hide the calendar and show year only

$(function() {
    $( "#datepicker" ).datepicker({dateFormat: 'yy'});
    });?

CSS

.ui-datepicker-calendar {
   display: none;
}

DEMO ?

You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

Here are the difference between POST, PUT and PATCH methods of a HTTP protocol.

POST

A HTTP.POST method always creates a new resource on the server. Its a non-idempotent request i.e. if user hits same requests 2 times it would create another new resource if there is no constraint.

http post method is like a INSERT query in SQL which always creates a new record in database.

Example: Use POST method to save new user, order etc where backend server decides the resource id for new resource.

PUT

In HTTP.PUT method the resource is first identified from the URL and if it exists then it is updated otherwise a new resource is created. When the target resource exists it overwrites that resource with a complete new body. That is HTTP.PUT method is used to CREATE or UPDATE a resource.

http put method is like a MERGE query in SQL which inserts or updates a record depending upon whether the given record exists.

PUT request is idempotent i.e. hitting the same requests twice would update the existing recording (No new record created). In PUT method the resource id is decided by the client and provided in the request url.

Example: Use PUT method to update existing user or order.

PATCH

A HTTP.PATCH method is used for partial modifications to a resource i.e. delta updates.

http patch method is like a UPDATE query in SQL which sets or updates selected columns only and not the whole row.

Example: You could use PATCH method to update order status.

PATCH /api/users/40450236/order/10234557

Request Body: {status: 'Delivered'}

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

You can use UIGraphicsBeginImageContext method to set the size of image same that of view.

Syntax : void UIGraphicsBeginImageContext(CGSize size);

 #define IMAGE(imageName) (UIImage *)[UIImage imageWithContentsOfFile:
  [[NSBundle mainBundle] pathForResource:imageName ofType:IMAGE_TYPE_PNG]]

        UIGraphicsBeginImageContext(self.view.frame.size);
        [[UIImage imageNamed:@“MyImage.png"] drawInRect:self.view.bounds];
        UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

    self.view.backgroundColor = [UIColor colorWithPatternImage:IMAGE(@"mainBg")];

Oracle does not have a simple database model like MySQL or MS SQL Server. I find the closest thing is to query the tablespaces and the corresponding users within them.

For example, I have a DEV_DB tablespace with all my actual 'databases' within them:

SQL> SELECT TABLESPACE_NAME FROM USER_TABLESPACES;

Resulting in:

SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
EXAMPLE
DEV_DB

It is also possible to query the users in all tablespaces:

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS;

Or within a specific tablespace (using my DEV_DB tablespace as an example):

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS where DEFAULT_TABLESPACE = 'DEV_DB';

ROLES DEV_DB
DATAWARE DEV_DB
DATAMART DEV_DB
STAGING DEV_DB

Create screen from Terminal:

screen -S <screen_name>

To see list of screens:

<screen -ls> or <screen -list>

To go to particular screen:

<screen -x screen_name>

<screen -r screen_name>

Inside screen

To Terminate screen:

give ctrl+d screen will get terminated

To Detach screen:

 give <ctrl+ad>or <screen -d >screen will get detached

To reattach screen:

screen -x <screen_name> or screen -r <screen_name>

To kill a screen from Terminal:

<screen -X -S screen_name quit> 

or

<screen -X -S screen_name kill>

You can use screen_name or process_id to execute commands.

You can define the variable inside the document ready function without var to make it a global variable. In javascript any variable declared without var automatically becomes a global variable

$(document).ready(function() {
    intro =  "something";
});

although you cant use the variable immediately, but it would be accessible to other functions

The answers are very good but there is another way in the latest release of MVC and .NET that I really like to use, instead of the "old school" FormCollection and Request keys.

Consider a HTML snippet contained within a form tag that either does an AJAX or FORM POST.

<input type="hidden"   name="TrackingID" 
<input type="text"     name="FirstName"  id="firstnametext" />
<input type="checkbox" name="IsLegal"  value="Do you accept terms and conditions?" />

Your controller will actually parse the form data and try to deliver it to you as parameters of the defined type. I included checkbox because it is a tricky one. It returns text "on" if checked and null if not checked. The requirement though is that these defined variables MUST exists (unless nullable(remember though that string is nullable)) otherwise the AJAX or POST back will fail.

[HttpPost]
public ActionResult PostBack(int TrackingID, string FirstName, string IsLegal){
    MyData.SaveRequest(TrackingID,FirstName, IsLegal == null ? false : true);
}

You can also post back a model without using any razor helpers. I have come across that this is needed some times.

public Class HomeModel
{
  public int HouseNumber { get; set; }
  public string StreetAddress { get; set; }
}

The HTML markup will simply be ...

<input type="text" name="variableName.HouseNumber" id="whateverid" >

and your controller(Razor Engine) will intercept the Form Variable "variableName" (name is as you like but keep it consistent) and try to build it up and cast it to MyModel.

[HttpPost]
public ActionResult PostBack(HomeModel variableName){
    postBack.HouseNumber; //The value user entered
    postBack.StreetAddress; //the default value of NULL.
}

When a controller is expecting a Model (in this case HomeModel) you do not have to define ALL the fields as the parser will just leave them at default, usually NULL. The nice thing is you can mix and match various models on the Mark-up and the post back parse will populate as much as possible. You do not need to define a model on the page or use any helpers.

TIP: The name of the parameter in the controller is the name defined in the HTML mark-up "name=" not the name of the Model but the name of the expected variable in the !

Using List<> is bit more complex in its mark-up.

<input type="text" name="variableNameHere[0].HouseNumber" id="id"           value="0">
<input type="text" name="variableNameHere[1].HouseNumber" id="whateverid-x" value="1">
<input type="text" name="variableNameHere[2].HouseNumber"                   value="2">
<input type="text" name="variableNameHere[3].HouseNumber" id="whateverid22" value="3">

Index on List<> MUST always be zero based and sequential. 0,1,2,3.

[HttpPost]
public ActionResult PostBack(List<HomeModel> variableNameHere){
     int counter = MyHomes.Count()
     foreach(var home in MyHomes)
     { ... }
}

Using IEnumerable<> for non zero based and non sequential indices post back. We need to add an extra hidden input to help the binder.

<input type="hidden" name="variableNameHere.Index" value="278">
<input type="text" name="variableNameHere[278].HouseNumber" id="id"      value="3">

<input type="hidden" name="variableNameHere.Index" value="99976">
<input type="text" name="variableNameHere[99976].HouseNumber" id="id3"   value="4">

<input type="hidden" name="variableNameHere.Index" value="777">
<input type="text" name="variableNameHere[777].HouseNumber" id="id23"    value="5">

And the code just needs to use IEnumerable and call ToList()

[HttpPost]
public ActionResult PostBack(IEnumerable<MyModel> variableNameHere){
     int counter = variableNameHere.ToList().Count()
     foreach(var home in variableNameHere)
     { ... }
}

It is recommended to use a single Model or a ViewModel (Model contianing other models to create a complex 'View' Model) per page. Mixing and matching as proposed could be considered bad practice, but as long as it works and is readable its not BAD. It does however, demonstrate the power and flexiblity of the Razor engine.

So if you need to drop in something arbitrary or override another value from a Razor helper, or just do not feel like making your own helpers, for a single form that uses some unusual combination of data, you can quickly use these methods to accept extra data.

make sure ,use this 404 route wrote on the bottom of the code.

syntax will be like

{
    path: 'page-not-found', 
    component: PagenotfoundComponent
},
{
    path: '**', 
    redirectTo: '/page-not-found'
},

Thank you

try

amtf =  amtf.Insert(amtf.Length - 2, ".");

No one seems to have picked that if (yes=no)>na or (no=na)>yes or (na=yes)>no, you get NULL as the result. Don't believe this is what you are after.

Here's also a more condensed form of the function, which works even if any of yes, no or na_ans is NULL.

USE [***]
GO
/****** Object:  UserDefinedFunction [dbo].[fnActionSq]    Script Date: 02/17/2011 10:21:47 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[fnTally] (@SchoolId nvarchar(50))
RETURNS nvarchar(3)
AS 
BEGIN
return (select (
       select top 1 Result from
       (select 'Yes' Result, yes_ans union all
        select 'No', no_ans union all
        select 'N/A', na_ans) [ ]
        order by yes_ans desc, Result desc)
       from dbo.qrc_maintally
       where school_id = @SchoolId)
End

Question 1: Unfortunately the one in which you you say is most intuitive is the least used in Android. As I understand, you should separate your UI (XML) and computational functionality (Java Class Files). It also makes for easier debugging. It is actually a lot easier to read this way and think about Android imo.

Question 2: I believe the two mainly used are #2 and #3. I will use a Button clickButton as an example.

2

is in the form of an anonymous class.

Button clickButton = (Button) findViewById(R.id.clickButton);
clickButton.setOnClickListener( new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                ***Do what you want with the click here***
            }
        });

This is my favorite as it has the onClick method right next to where the button variable was set with the findViewById. It seems very neat and tidy that everything that deals with this clickButton Button View is located here.

A con that my coworker comments, is that imagine you have many views that need onclick listener. You can see that your onCreate will get very long in length. So that why he likes to use:

3

Say you have, 5 clickButtons:

Make sure your Activity/Fragment implement OnClickListener

// in OnCreate

Button mClickButton1 = (Button)findViewById(R.id.clickButton1);
mClickButton1.setOnClickListener(this);
Button mClickButton2 = (Button)findViewById(R.id.clickButton2);
mClickButton2.setOnClickListener(this);
Button mClickButton3 = (Button)findViewById(R.id.clickButton3);
mClickButton3.setOnClickListener(this);
Button mClickButton4 = (Button)findViewById(R.id.clickButton4);
mClickButton4.setOnClickListener(this);
Button mClickButton5 = (Button)findViewById(R.id.clickButton5);
mClickButton5.setOnClickListener(this);


// somewhere else in your code

public void onClick(View v) {
    switch (v.getId()) {
        case  R.id.clickButton1: {
            // do something for button 1 click
            break;
        }

        case R.id.clickButton2: {
            // do something for button 2 click
            break;
        }

        //.... etc
    }
}

This way as my coworker explains is neater in his eyes, as all the onClick computation is handled in one place and not crowding the onCreate method. But the downside I see is, that the:

1. views themselves,
2. and any other object that might be located in onCreate used by the onClick method will have to be made into a field.

Let me know if you would like more information. I didn't answer your question fully because it is a pretty long question. And if I find some sites I will expand my answer, right now I'm just giving some experience.

I incurred this error once.

You need to use callbacks. That's how asynchronous IO works. Btw sys.puts is deprecated

.net core

using System.Text.Json;

To serialize

var jsonStr = JsonSerializer.Serialize(MyObject)

Deserialize

var weatherForecast = JsonSerializer.Deserialize<MyObject>(jsonStr);

In Android, application-level meta data is accessed through the Context reference, which an activity is a descendant of.

For example, you can get the source directory via the getApplicationInfo().sourceDir property. There are methods for other folders as well (assets directory, data dir, database dir, etc.).

I get it resolved appending datetime as an random number:

$http.get("/your_url?rnd="+new Date().getTime()).success(function(data, status, headers, config) {
    console.log('your get response is new!!!');
});

TimeSpan.FromTicks(28000000000).TotalMinutes;

The Spring documentation describes the following standard scopes:

singleton: (Default) Scopes a single bean definition to a single object instance per Spring IoC container.

prototype: Scopes a single bean definition to any number of object instances.

request: Scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext.

session: Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext.

global session: Scopes a single bean definition to the lifecycle of a global HTTP Session. Typically only valid when used in a portlet context. Only valid in the context of a web-aware Spring ApplicationContext.

Additional custom scopes can also be created and configured using a CustomScopeConfigurer. An example would be the flow scope added by Spring Webflow.

By the way, you argues that you always used prototype what I find strange. The standard scope is singleton and in the application I develop, I rarely need the prototype scope. You should maybe take a look at this.

Just add the following code:

setIconImage(new ImageIcon(PathOfFile).getImage());

I have executed the code in my machine its working for IE and FF also.

function closeSelf(){
    // do something

    if(condition satisfied){
       alert("conditions satisfied, submiting the form.");
       document.forms['certform'].submit();
       window.close();
    }else{
       alert("conditions not satisfied, returning to form");    
    }
}


<form action="/system/wpacert" method="post" enctype="multipart/form-data" name="certform">
       <div>Certificate 1: <input type="file" name="cert1"/></div>
       <div>Certificate 2: <input type="file" name="cert2"/></div>
       <div>Certificate 3: <input type="file" name="cert3"/></div>

       // change the submit button to normal button
       <div><input type="button" value="Upload"  onclick="closeSelf();"/></div>
</form>

Use double quote to enclose the quote or escape it.

newTemp = mystring.replace(/"/g, "'");

or

newTemp = mystring.replace(/"/g, '\'');

I needed to install various JetBrains tools on a number of machines from CLI, so I wrote a tiny tool to help with that. It also uses cleaner APIs from JB making it hopefully more stable, and works for various JB tools.

Just solved this problem! I know the question is quite old, but I just had this same problem and none of the answers above helped to solve it.

Assuming the actual domain name you want to use is specified in your c:\windows\System32\drivers\etc\hosts and your configurations in apache\conf\httpd.conf and apache\conf\extra\httpd-vhots.conf are right, your problem might be the same as mine:

In Apache's htdocs directory I had a shortcut linking to the actual project I wanted to see in the browser. It turns out, Apache doesn't understand shortcuts. My solution was to create a proper symlink:

In windows, and within the httdocs directory, I ran this command in the terminal:

mklink /d ple <your project directory with index.html> 

This created a proper symlink in the httpdocs directory. After restarting the Apache service and then reloading the page, I was able to see my website up :)

If you are using linux and faced such problem during creating link, try to change jar file path of original jmeter file.

+ java -server -XX:+HeapDumpOnOutOfMemoryError -Xms512m -Xmx512m -XX:NewSize=128m -XX:MaxNewSize=128m -XX:MaxTenuringThreshold=2 -XX:PermSize=64m -XX:MaxPermSize=128m -XX:+CMSClassUnloadingEnabled -jar ./ApacheJMeter.jar -help

Change to:

java $ARGS $JVM_ARGS -jar "/opt/apache-jmeter-2.11/bin/ApacheJMeter.jar" "$@"

You need some JS to do scroll events. The best way to do this is to set a new CSS class for the fixed position that will get assigned to the relevant div when scrolling goes past a certain point.

HTML

<div class="sticky"></div>

CSS

.fixed {
    position: fixed;
    top:0; left:0;
    width: 100%; }

jQuery

$(window).scroll(function(){
  var sticky = $('.sticky'),
      scroll = $(window).scrollTop();

  if (scroll >= 100) sticky.addClass('fixed');
  else sticky.removeClass('fixed');
});

Example fiddle: http://jsfiddle.net/gxRC9/501/

EDIT: Extended example

If the trigger point is unknown but should be whenever the sticky element reaches the top of the screen, offset().top can be used.

var stickyOffset = $('.sticky').offset().top;

$(window).scroll(function(){
  var sticky = $('.sticky'),
      scroll = $(window).scrollTop();

  if (scroll >= stickyOffset) sticky.addClass('fixed');
  else sticky.removeClass('fixed');
});

Extended example fiddle: http://jsfiddle.net/gxRC9/502/

I don't think you need to change the MaxPermSize to 1024m. This works for me:

-startup

$userinput = "http://www.example.vn/";
//$url = urlencode($userinput);
$input = @file_get_contents($userinput) or die("Could not access file: $userinput");
$regexp = "<tagname\s[^>]*>(.*)<\/tagname>";
//==Example:
//$regexp = "<div\s[^>]*>(.*)<\/div>";

if(preg_match_all("/$regexp/siU", $input, $matches, PREG_SET_ORDER)) {
    foreach($matches as $match) {
        // $match[2] = link address 
        // $match[3] = link text
    }
}

Try this

function readRows() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var rows = sheet.getDataRange();
  var numRows = rows.getNumRows();
  //var values = rows.getValues();

  var Names = sheet.getRange("A2:A7");
  var Name = [
    Names.getCell(1, 1).getValue(),
    Names.getCell(2, 1).getValue(),
    .....
    Names.getCell(5, 1).getValue()]

You can define arrays simply as follows, instead of allocating and then assigning.

var arr = [1,2,3,5]

Your initial error was because of the following line, and ones like it

var Name[0] = Name_cell.getValue(); 

Since Name is already defined and you are assigning the values to its elements, you should skip the var, so just

Name[0] = Name_cell.getValue();

Pro tip: For most issues that, like this one, don't directly involve Google services, you are better off Googling for the way to do it in javascript in general.

Position the cursor under the variables -> right-click -> Generate -> Getter and Setter -> Choose the variables to make the get and set

or

Alt + Insert -> Getter and Setter -> Choose the variables

In a completely different and simpler perspective:

• if you are relying on Google for showing your maps, markers, polygons, whatever, then let the calculations be done by Google!
• you save resources on your server and you simply store the latitude and longitude together as a single string (VARCHAR), E.g.: "-0000.0000001,-0000.000000000000001" (35 length and if a number has more than 7 decimal digits then it gets rounded);
• if Google returns more than 7 decimal digits per number, you can get that data stored in your string anyway, just in case you want to detect some flees or microbes in the future;
• you can use their distance matrix or their geometry library for calculating distances or detecting points in certain areas with calls as simple as this: google.maps.geometry.poly.containsLocation(latLng, bermudaTrianglePolygon))
• there are plenty of "server-side" APIs you can use (in Python, Ruby on Rails, PHP, CodeIgniter, Laravel, Yii, Zend Framework, etc.) that use Google Maps API.

This way you don't need to worry about indexing numbers and all the other problems associated with data types that may screw up your coordinates.

If you want a string, then the other answers are fine, but if what you're looking for is the first few letters as characters you can access them as a list:

your_text.chars.take(30)

It's not that different in bash.

workdone=0
while : ; do
  ...
  if [ "$workdone" -ne 0 ]; then
      break
  fi
done

: is the no-op command; its exit status is always 0, so the loop runs until workdone is given a non-zero value.

There are many ways you could set and test the value of workdone in order to exit the loop; the one I show above should work in any POSIX-compatible shell.

It will help you in linked list.

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

No, that's about as efficient as you're going to get. You could write a C program which could do the job a little faster (less startup time and processing arguments) but it will probably tend towards the same speed as sed as files get large (and I assume they're large if it's taking a minute).

But your question suffers from the same problem as so many others in that it pre-supposes the solution. If you were to tell us in detail what you're trying to do rather then how, we may be able to suggest a better option.

For example, if this is a file A that some other program B processes, one solution would be to not strip off the first line, but modify program B to process it differently.

Let's say all your programs append to this file A and program B currently reads and processes the first line before deleting it.

You could re-engineer program B so that it didn't try to delete the first line but maintains a persistent (probably file-based) offset into the file A so that, next time it runs, it could seek to that offset, process the line there, and update the offset.

Then, at a quiet time (midnight?), it could do special processing of file A to delete all lines currently processed and set the offset back to 0.

It will certainly be faster for a program to open and seek a file rather than open and rewrite. This discussion assumes you have control over program B, of course. I don't know if that's the case but there may be other possible solutions if you provide further information.

According to the standard (§6.4.4.4/10)

The value of an integer character constant containing more than one character (e.g., 'ab'), [...] is implementation-defined.

long x = '\xde\xad\xbe\xef'; // yes, single quotes

This is valid ISO 9899:2011 C. It compiles without warning under gcc with -Wall, and a “multi-character character constant” warning with -pedantic.

From Wikipedia:

Multi-character constants (e.g. 'xy') are valid, although rarely useful — they let one store several characters in an integer (e.g. 4 ASCII characters can fit in a 32-bit integer, 8 in a 64-bit one). Since the order in which the characters are packed into one int is not specified, portable use of multi-character constants is difficult.

For portability sake, don't use multi-character constants with integral types.

If you just want to change the size font dynamically then you can:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, resources.getDimension(R.dimen.tutorial_cross_marginTop))

As @achie's answer, you can get the dp from dimens.xml like this:

val dpValue = (resources.getDimension(R.dimen.tutorial_cross_marginTop)/ resources.displayMetrics.density).toInt()

or get sp like this

val spValue = (resources.getDimension(R.dimen.font_size)/ resources.displayMetrics.scaledDensity).toInt()

About Resources.java #{getDimension}

    /**

It can also be solved using the following query along with other answers.

WITH purchase_data AS (
        SELECT address_id, purchased_at, product_id,
                row_number() OVER (PARTITION BY address_id ORDER BY purchased_at DESC) AS row_number
        FROM purchases
        WHERE product_id = 1)
SELECT address_id, purchased_at, product_id
FROM purchase_data where row_number = 1

As an addendum, if you want to reapply your changes on top of the remote, you can also try:

git pull --rebase origin master

If you then want to undo some of your changes (but perhaps not all of them) you can use:

git reset SHA_HASH

Then do some adjustment and recommit.

For those new to database .... and need to ALTER an existing table. A lot things seem to be pretty straightforward, but there is always something ... between A and B.

Before anything else, take a look at this.

1. Make sure you have P_ID (parent ID on both parent and child table).
2. Of course it will be already filled in the parent. Not necessarily in the child in a true and final way. So for instance P_ID #3 (maybe many times in the child table will be pointing to original P_ID at parent table).

3. Go to SQL tab (I am using phpMyAdmin, should be similar in other ones) and do this command:

   ALTER TABLE child_table_name    
   ADD FOREIGN KEY (P_ID)   
   REFERENCES parent_table_name (P_ID)
   

4. Click on child table, than structure, finally on relational view. Finish your DB planning there. There was a nice answer before this one about cascade, restrict, etc. Of course it could be done by commands...

I had the same problem. I ran an index defrag process but the transaction log became full and the defrag process errored out. The transaction log remained large.

I backed up the transaction log then proceeded to shrink the transaction log .ldf file. However the transaction log did not shrink at all.

I then issued a "CHECKPOINT" followed by "DBCC DROPCLEANBUFFER" and was able to shrink the transaction log .ldf file thereafter

More universal can be: for each v Selection : v.value = "'" & v.value : next and selecting range of cells before execution

Add this in your js file:

$http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";

and add this to your server file:

$params = json_decode(file_get_contents('php://input'), true);

That should work.

For such case, you can do like this

@foreach (json_decode($leads->member) as $member)
     {{ $genre }}
@endforeach

Try this:

<uses-permission android:name="android.permission.INTERNET"/>

And your activity namesmust be like this with capital letters:

<activity android:name=".Addfriend"/>
    <activity android:name=".UpdateDetails"/>
    <activity android:name=".Details"/>
    <activity android:name=".Updateimage"/>

yes - take a look at setInterval and setTimeout for executing code at certain times. setInterval would be the one to use to execute code periodically.

See a demo and answer here for usage

for (String name : new ArrayList<String>(names)) {
    // Do something
    names.remove(nameToRemove);
}

You clone the list names and iterate through the clone while you remove from the original list. A bit cleaner than the top answer.

I want to note that the XIB editor offers you the following standard options:

Section: blue/gray/none

(the right-hand column with options, 4th tab, first group "Table View Cell", 4th subgroup, the 1st of 3 items reads "Selection")

Probably what you want to do may be achieved by selecting the right standard option.

A class that will play a WAV file, blocking until the sound has finished playing:

class Sound implements Playable {

    private final Path wavPath;
    private final CyclicBarrier barrier = new CyclicBarrier(2);

    Sound(final Path wavPath) {

        this.wavPath = wavPath;

        try (final AudioInputStream audioIn = AudioSystem.getAudioInputStream(wavPath.toFile());
             final Clip clip = AudioSystem.getClip()) {

            listenForEndOf(clip);
            clip.open(audioIn);
            clip.start();
            waitForSoundEnd();
        }
    }

    private void listenForEndOf(final Clip clip) {

        clip.addLineListener(event -> {
            if (event.getType() == LineEvent.Type.STOP) waitOnBarrier();
        });
    }

    private void waitOnBarrier() {

        try {

            barrier.await();
        } catch (final InterruptedException ignored) {
        } catch (final BrokenBarrierException e) {

            throw new RuntimeException(e);
        }
    }

    private void waitForSoundEnd() {

        waitOnBarrier();
    }
}

This happens because the current account you have used to log in probably has very limited priviledges.

To fix this problem, you can change your the AllowNoPassword config setting to false in config.inc.php. You may also force the authentication to use the config file and specify the default username and password .

$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = ''; // leave blank if no password

After this, the PhPMyAdmin login page should show up when you refresh the page. You can then log in with the default root password.

More details can be found on this post ..

Well using find is the best option here

just simply use like this

$(".class").click(function(){
        $("this").find('.subclass').css("visibility","visible");
})

and if there are many classes with the same name class its always better to give the class name of parent class like this

$(".parent .class").click(function(){
            $("this").find('.subclass').css("visibility","visible");
    })

All of the information you are looking for can be found here and here (thanks Reed Copsey):

From the first link:

Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.

...

The access level for class members and struct members, including nested classes and structs, is private by default.

...

interfaces default to internal access.

...

Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.

From the second link:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

And for nested types:

Members of    Default member accessibility
----------    ----------------------------
enum          public
class         private
interface     public
struct        private

sb.Append(Environment.Newline);
sb.Append("\t");

C does not have its own String data type like Java.

Only we can declare String datatype in C using character array or character pointer For example :

 char message[10]; 
 or 
 char *message;

But you need to declare at least:

    char message[14]; 

to copy "Hello, world!" into message variable.

• 13 : length of the "Hello, world!"
• 1 : for '\0' null character that identifies end of the string

It really depends on what kind of type safety you need. The non-generic way of doing it is best done as:

 Map x = new HashMap();

Note that x is typed as a Map. this makes it much easier to change implementations (to a TreeMap or a LinkedHashMap) in the future.

You can use generics to ensure a certain level of type safety:

Map<String, Object> x = new HashMap<String, Object>();

In Java 7 and later you can do

Map<String, Object> x = new HashMap<>();

The above, while more verbose, avoids compiler warnings. In this case the content of the HashMap can be any Object, so that can be Integer, int[], etc. which is what you are doing.

If you are still using Java 6, Guava Libraries (although it is easy enough to do yourself) has a method called newHashMap() which avoids the need to duplicate the generic typing information when you do a new. It infers the type from the variable declaration (this is a Java feature not available on constructors prior to Java 7).

By the way, when you add an int or other primitive, Java is autoboxing it. That means that the code is equivalent to:

 x.put("one", Integer.valueOf(1));

You can certainly put a HashMap as a value in another HashMap, but I think there are issues if you do it recursively (that is put the HashMap as a value in itself).

It works like a charm someone can try this. Here I have used soft delete checker. You could omit the last: id,deleted_at, NULL if your model doesn't have soft delete implementation.

public function rules()
{
    switch ($this->method()) {
        case 'PUT':
            $emailRules = "required|unique:users,email,{$this->id},id,deleted_at,NULL";
            break;
        default:
            $emailRules = "required|unique:users,email,NULL,id,deleted_at,NULL";
            break;
    }

    return [
        'email' => $emailRules,
        'display_name' => 'nullable',
        'description' => 'nullable',
    ];
}

Thank you.

.wrapper{

    width: 100%;
    overflow: hidden;
}
.side{
    float:left;
    width:20%;
}
.main{
    float:right;

Add the 'interact' Expect command just before your EOD:

#!/bin/bash

read -s PWD

/usr/bin/expect <<EOD
spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no usr@$myhost.example.com
expect "password"
send "$PWD\n"
interact
EOD
echo "you're out"

This should let you interact with the remote machine until you log out. Then you'll be back in Bash.

The code provided by this answer is right, but incomplete, I've tested it. There are missing properties in "UserEmail" class:

It looks as if you were on the right track. You just need to add the else statement after the ";" following the "then" statement. Also I would split the first line from the second line with a semicolon instead of joining it with "&&".

maxline='cat journald.conf | grep "#SystemMaxUse="'; if [ $maxline == "#SystemMaxUse=" ]; then sed 's/\#SystemMaxUse=/SystemMaxUse=50M/g' journald.conf > journald.conf2 && mv journald.conf2 journald.conf; else echo "This file has been edited. You'll need to do it manually."; fi

Also in your original script, when declaring maxline you used back-ticks "`" instead of single quotes "'" which might cause problems.

If you want to use an array, you have to keep a counter which contains the number of cars in the garage. Better use an ArrayList instead of array:

List<Car> garage = new ArrayList<Car>();
garage.add(redCar);

Take care not to include

#include <string.h> 

but only

#include <string>

It took me 1 hour to find this in my code.

Hope this can help

Using environment variable is sometimes more convenient when you do not control the build scripts / process.

For C includes use C_INCLUDE_PATH.

For C++ includes use CPLUS_INCLUDE_PATH.

See this link for other gcc environment variables.

Example usage in MacOS / Linux

# `pip install` will automatically run `gcc` using parameters
# specified in the `asyncpg` package (that I do not control)

C_INCLUDE_PATH=/home/scott/.pyenv/versions/3.7.9/include/python3.7m pip install asyncpg

Example usage in Windows

set C_INCLUDE_PATH="C:\Users\Scott\.pyenv\versions\3.7.9\include\python3.7m"

pip install asyncpg

# clear the environment variable so it doesn't affect other builds
set C_INCLUDE_PATH=

The ones I can think of are

Existential types

def foo(l: List[Option[_]]) = ...

Higher kinded type parameters

case class A[K[_],T](a: K[T])

Ignored variables

val _ = 5

Ignored parameters

List(1, 2, 3) foreach { _ => println("Hi") }

Ignored names of self types

trait MySeq { _: Seq[_] => }

Wildcard patterns

Some(5) match { case Some(_) => println("Yes") }

Wildcard patterns in interpolations

"abc" match { case s"a$_c" => }

Sequence wildcard in patterns

C(1, 2, 3) match { case C(vs @ _*) => vs.foreach(f(_)) }

Wildcard imports

import java.util._

Hiding imports

import java.util.{ArrayList => _, _}

Joining letters to operators

def bang_!(x: Int) = 5

Assignment operators

def foo_=(x: Int) { ... }

Placeholder syntax

List(1, 2, 3) map (_ + 2)

Method values

List(1, 2, 3) foreach println _

Converting call-by-name parameters to functions

def toFunction(callByName: => Int): () => Int = callByName _

Default initializer

var x: String = _   // unloved syntax may be eliminated

There may be others I have forgotten!

Example showing why foo(_) and foo _ are different:

This example comes from 0__:

trait PlaceholderExample {
  def process[A](f: A => Unit)

  val set: Set[_ => Unit]

  set.foreach(process _) // Error 
  set.foreach(process(_)) // No Error
}

In the first case, process _ represents a method; Scala takes the polymorphic method and attempts to make it monomorphic by filling in the type parameter, but realizes that there is no type that can be filled in for A that will give the type (_ => Unit) => ? (Existential _ is not a type).

In the second case, process(_) is a lambda; when writing a lambda with no explicit argument type, Scala infers the type from the argument that foreach expects, and _ => Unit is a type (whereas just plain _ isn't), so it can be substituted and inferred.

This may well be the trickiest gotcha in Scala I have ever encountered.

Note that this example compiles in 2.13. Ignore it like it was assigned to underscore.

I needed a non-interactive method for cloning a private repo.

Inspired by this issue: https://github.com/github/hub/issues/1644

Step 2.

I had the same problem. My customer ordered me Python 3.4 script that updates XLS (not XLSX) Excel files.

The 1st package xlrd was installed by "pip install" without problems in my Python home.

The 2nd one xlwt needed to say "pip install xlwt-future" to be compatible.

The 3rd one xlutils has no support for Python 3, but I adapted it a little bit and now it works at least for dummy script:

#!C:\Python343\python
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
from xlwt import easyxf # http://pypi.python.org/pypi/xlwt

file_path = 'C:\Dev\Test_upd.xls'
rb = open_workbook('C:\Dev\Test.xls',formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
w_sheet.write(1, 1, 'Value')
wb.save(file_path)

I attached the file here: http://ifolder.su/43507580

Write to [email protected] if it got expired.

P.S.: Some functions are not called in the dummy example, so maybe they will need for an adaptation also. Who wants to do it, fix exceptions one-by-one with a google help. It's not a very difficult task, because the package code is small...

With async functions and promises, it now can work as simply as this:

async function foobar() {
  await $("#example").fadeOut().promise();
  doSomethingElse();
  await $("#example").fadeIn().promise();
}

This worked for me with 5 images in diferent sizes.

1. Create a container div
2. An Unordered list for the images
3. On css the unordened must be displayed vertically and without bullets
4. Justify content of container div

This works because of justify-content:space-between, and it's on a list, displayed horizontally.

On CSS

 #container {
            display: flex;
            justify-content: space-between;
 }
    #container ul li{ display:inline; list-style-type:none;
}

On html

<div id="container"> 
  <ul>  
        <li><img src="box1.png"><li>
        <li><img src="box2.png"><li>
        <li><img src="box3.png"><li>
        <li><img src="box4.png"><li>
        <li><img src="box5.png"><li>
    </ul>

You can copy those two functions (listed below), and use them to escape/unescape all quotes and special characters. You don't have to use jQuery or any other library for this.

function escape(s) {
    return ('' + s)
        .replace(/\\/g, '\\\\')
        .replace(/\t/g, '\\t')
        .replace(/\n/g, '\\n')
        .replace(/\u00A0/g, '\\u00A0')
        .replace(/&/g, '\\x26')
        .replace(/'/g, '\\x27')
        .replace(/"/g, '\\x22')
        .replace(/</g, '\\x3C')
        .replace(/>/g, '\\x3E');
}

function unescape(s) {
    s = ('' + s)
       .replace(/\\x3E/g, '>')
       .replace(/\\x3C/g, '<')
       .replace(/\\x22/g, '"')
       .replace(/\\x27/g, "'")
       .replace(/\\x26/g, '&')
       .replace(/\\u00A0/g, '\u00A0')
       .replace(/\\n/g, '\n')
       .replace(/\\t/g, '\t');

    return s.replace(/\\\\/g, '\\');
}

To answer this question from my understanding...

An authentication system that uses REST so that you do not need to actually track or manage the users in your system. This is done by using the HTTP methods POST, GET, PUT, DELETE. We take these 4 methods and think of them in terms of database interaction as CREATE, READ, UPDATE, DELETE (but on the web we use POST and GET because that is what anchor tags support currently). So treating POST and GET as our CREATE/READ/UPDATE/DELETE (CRUD) then we can design routes in our web application that will be able to deduce what action of CRUD we are achieving.

For example, in a Ruby on Rails application we can build our web app such that if a user who is logged in visits http://store.com/account/logout then the GET of that page can viewed as the user attempting to logout. In our rails controller we would build an action in that logs the user out and sends them back to the home page.

A GET on the login page would yield a form. a POST on the login page would be viewed as a login attempt and take the POST data and use it to login.

To me, it is a practice of using HTTP methods mapped to their database meaning and then building an authentication system with that in mind you do not need to pass around any session id's or track sessions.

I'm still learning -- if you find anything I have said to be wrong please correct me, and if you learn more post it back here. Thanks.

Using Twitter Bootstrap classes may be the best choice :

• pull-left makes an element floating left
• clearfix allows the element to contain floating elements (if not already set via another class)

<div class="paragraphs">
  <div class="row">
    <div class="span4">
      <div class="clearfix content-heading">
          <img class="pull-left" src="../site/img/success32.png"/>
          <h3>Experience &nbsp </h3>
      </div>
      <p>Donec id elit non mi porta gravida at eget metus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui.</p>
    </div>
  </div>
</div>

You can use strpos() or stripos() to check if the string contain the given needle. It will return the position where it was found, otherwise will return FALSE.

Use the operators === or `!== to differ FALSE from 0 in PHP.

The JSON string will just be the body of the response you get back from the URL you have called. So add this code

...
BufferedReader in = new BufferedReader(new InputStreamReader(
                            conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) 
    System.out.println(inputLine);
in.close();

That will allow you to see the JSON being returned to the console. The only missing piece you then have is using a JSON library to read that data and provide you with a Java representation.

Here's an example using JSON-LIB

Two ways I can think of are

var TestApp = React.createClass({
    getComponent: function(index) {
        $(this.getDOMNode()).find('li:nth-child(' + index + ')').css({
            'background-color': '#ccc'
        });
    },
    render: function() {
        return (
            <div>
              <ul>
                <li onClick={this.getComponent.bind(this, 1)}>Component 1</li>
                <li onClick={this.getComponent.bind(this, 2)}>Component 2</li>
                <li onClick={this.getComponent.bind(this, 3)}>Component 3</li>
              </ul>
            </div>
        );
    }
});
React.renderComponent(<TestApp /> , document.getElementById('soln1'));

This is my personal favorite.

var ListItem = React.createClass({
    getInitialState: function() {
        return {
            isSelected: false
        };
    },
    handleClick: function() {
        this.setState({
            isSelected: true
        })
    },
    render: function() {
        var isSelected = this.state.isSelected;
        var style = {
            'background-color': ''
        };
        if (isSelected) {
            style = {
                'background-color': '#ccc'
            };
        }
        return (
            <li onClick={this.handleClick} style={style}>{this.props.content}</li>
        );
    }
});

var TestApp2 = React.createClass({
    getComponent: function(index) {
        $(this.getDOMNode()).find('li:nth-child(' + index + ')').css({
            'background-color': '#ccc'
        });
    },
    render: function() {
        return (
            <div>
             <ul>
              <ListItem content="Component 1" />
              <ListItem content="Component 2" />
              <ListItem content="Component 3" />
             </ul>
            </div>
        );
    }
});
React.renderComponent(<TestApp2 /> , document.getElementById('soln2'));

Here is a DEMO

I hope this helps.

This is a pretty simple approach and doesn't experience a lot of the edge cases in the existing answers.

// Invalid Date.getTime() will produce NaN
if (date instanceof Date && date.getTime()) {
    console.log("is date!");
}

It won't fire with other objects like numbers, makes sure the value is actually a Date (rather than an object that looks like one), and it avoids Invalid Dates.

The HTTP Content-Type for .ogg should be application/ogg (video/ogg for .ogv) and for .mp4 it should be video/mp4. You can check using the Web Sniffer.

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

require_once dirname(__FILE__). '/../script/pdocrud.php';

This one worked for me, try this

[RegularExpression("^[a-zA-Z &\-@.]*$", ErrorMessage = "--Your Message--")]

With Laravel 5.6, if you want pass multiple emails with names, you need to pass array of associative arrays. Example pushing multiple recipients into the $to array:

$to[] = array('email' => $email, 'name' => $name);

Fixed two recipients:

$to = [['email' => '[email protected]', 'name' => 'User One'], 
       ['email' => '[email protected]', 'name' => 'User Two']];

The 'name' key is not mandatory. You can set it to 'name' => NULL or do not add to the associative array, then only 'email' will be used.

Having 2 scripts called test.bat and ping.bat in same folder:

Script test.bat contains one line:

ping google.com

Script ping.bat contains below lines:

@echo off
echo Hello!
pause

Executing "test.bat" the result on CMD will be:

Hello!
Press any key to continue . . .

Why? Because "test.bat" is calling the "ping.bat" ("ping google.com" is interpreted as calling the "ping.bat" script). Same is happening if script "ping.bat" contains "ping google.com". The script will execute himself in a loop.

Easy ways to avoid this:

1. Do not name your script "ping.bat".
2. You can name the script as "ping.bat" but inside the script use "ping.exe google.com" instead of "ping google.com".

Instanceof works if you don't depend on specific classes, but also keep in mind that you can have nulls in the list, so obj.getClass() will fail, but instanceof always returns false on null.

You can think of an iframe as an embedded browser window that you can put on an HTML page to show another URL inside it. This URL can be totally distinct from your web site/app.

You can put an iframe in any HTML page, so you could put one inside a contentplaceholder in a webform that has a Masterpage and it will appear with whatever URL you load into it (via Javascript, or C# if you turn your iframe into a server-side control (runat='server') on the final HTML page that your webform produces when requested.

And you can load a URL into your iframe that is a .aspx page.

But - iframes have nothing to do with the ASP.net mechanism. They are HTML elements that can be made to run server-side, but they are essentially 'dumb' and unmanaged/unconnected to the ASP.Net mechanisms - don't confuse a Contentplaceholder with an iframe.

Incidentally, the use of iframes is still contentious - do you really need to use one? Can you afford the negative trade-offs associated with them e.g. lack of navigation history ...?

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

Ahh. Because I missed the point of you initial post, here is an example which also ITERATES. The first example did not. In this case, I retreive an ADODB recordset, then load the data into a collection, which is returned by the function to client code:

EDIT: Not sure what I screwed up in pasting the code, but the formatting is a little screwball. Sorry!

Dim cn As ADODB.Connection
Dim cmd As ADODB.Command
Dim rs As ADODB.Recordset
Dim colReturn As New Collection

Set colReturn = New Collection

Dim SQL As String
SQL = _
    "SELECT tblState.State, tblState.StateName " & _
    "FROM tblState"

Set cn = New ADODB.Connection
Set cmd = New ADODB.Command

    .Provider = DataConnection.MyADOProvider

DOM is a logical model that can be implemented in any convenient manner.It is based on an object structure that closely resembles the structure of the documents it models.

Here's an approach using generators:

function* square(n) {
    for (var i = 0; i < n; i++ ) yield i*i;
}

Then you can write

console.log(...square(7));

Another idea is:

[...Array(5)].map((_, i) => i*i)

Array(5) creates an unfilled five-element array. That's how Array works when given a single argument. We use the spread operator to create an array with five undefined elements. That we can then map. See http://ariya.ofilabs.com/2013/07/sequences-using-javascript-array.html.

Alternatively, we could write

Array.from(Array(5)).map((_, i) => i*i)

or, we could take advantage of the second argument to Array#from to skip the map and write

Array.from(Array(5), (_, i) => i*i)

A horrible hack which I saw recently, which I do not recommend you use, is

[...1e4+''].map((_, i) => i*i)

=SUMPRODUCT( (MONTH($A$2:$A$6)=1) * ($B$2:$B$6) )

Explanation:

• (MONTH($A$2:$A$6)=1) creates an array of 1 and 0, it's 1 when the month is january, thus in your example the returned array would be [1, 1, 1, 0, 0]

• SUMPRODUCT first multiplies each value of the array created in the above step with values of the array ($B$2:$B$6), then it sums them. Hence in your example it does this: (1 * 430) + (1 * 96) + (1 * 440) + (0 * 72.10) + (0 * 72.30)

This works also in OpenOffice and Google Spreadsheets

DECLARE @FDate DATETIME='05-05-2019' /*This is first date*/
 GETDATE()/*This is Current date*/
SELECT (DATEDIFF(DAY,(@LastDate),GETDATE())) As DifferenceDays/*this query will return no of days between firstdate & Current date*/

I got the same problem. This code works well on my case.

// Replace broken images by a default img
$('img').each(function(){
    if($(this).attr('src') === ''){
      this.src = '/default_feature_image.png';
    }
});

Something I wrote up incase anyone comes across an issue with people hitting backspace while thinking they are in a form field

window.addEventListener("keydown", function(e){
    /*
     * keyCode: 8
     * keyIdentifier: "U+0008"
    */
    if(e.keyCode === 8 && document.activeElement !== 'text') {
        e.preventDefault();
        alert('Prevent page from going back');
    }
});

No need for cut or magic, in bash you can cut a string like so:

  ORGSTRING="123456"
  CUTSTRING=${ORGSTRING:0:-3}
  echo "The original string: $ORGSTRING"
  echo "The new, shorter and faster string: $CUTSTRING"

In C++11 it is possible:

auto array = new double[M][N]; 

This way, the memory is not initialized. To initialize it do this instead:

auto array = new double[M][N]();

Sample program (compile with "g++ -std=c++11"):

#include <iostream>
#include <utility>
#include <type_traits>
#include <typeinfo>
#include <cxxabi.h>
using namespace std;

int main()
{
    const auto M = 2;
    const auto N = 2;

    // allocate (no initializatoin)
    auto array = new double[M][N];

    // pollute the memory
    array[0][0] = 2;
    array[1][0] = 3;
    array[0][1] = 4;
    array[1][1] = 5;

    // re-allocate, probably will fetch the same memory block (not portable)
    delete[] array;
    array = new double[M][N];

    // show that memory is not initialized
    for(int r = 0; r < M; r++)
    {
        for(int c = 0; c < N; c++)
            cout << array[r][c] << " ";
        cout << endl;
    }
    cout << endl;

    delete[] array;

    // the proper way to zero-initialize the array
    array = new double[M][N]();

    // show the memory is initialized
    for(int r = 0; r < M; r++)
    {
        for(int c = 0; c < N; c++)
            cout << array[r][c] << " ";
        cout << endl;
    }

    int info;
    cout << abi::__cxa_demangle(typeid(array).name(),0,0,&info) << endl;

    return 0;
}

Output:

2 4 
3 5 

0 0 
0 0 
double (*) [2]

You could define a name for the VLOOKUP part of the formula.

1. Highlight the cell that contains this formula
2. On the Insert menu, go Name, and click Define
3. Enter a name for your variable (e.g. 'Value')
4. In the Refers To box, enter your VLOOKUP formula: =VLOOKUP(A1,B:B, 1, 0)
5. Click Add, and close the dialog
6. In your original formula, replace the VLOOKUP parts with the name you just defined: =IF( Value > 10, Value - 10, Value )

Step (1) is important here: I guess on the second row, you want Excel to use VLOOKUP(A2,B:B, 1, 0), the third row VLOOKUP(A3,B:B, 1, 0), etc. Step (4) achieves this by using relative references (A1 and B:B), not absolute references ($A$1 and $B:$B).

Note:

1. For newer Excel versions with the ribbon, go to Formulas ribbon -> Define Name. It's the same after that. Also, to use your name, you can do "Use in Formula", right under Define Name, while editing the formula, or else start typing it, and Excel will suggest the name (credits: Michael Rusch)

2. Shortened steps: 1. Right click a cell and click Define name... 2. Enter a name and the formula which you want to associate with that name/local variable 3. Use variable (credits: Jens Bodal)

Why is this blocked by Java?

You'd have to ask the Java designers. There might be some subtle grammatical reason for the restriction. Note that some of the array creation / initialization constructs were not in Java 1.0, and (IIRC) were added in Java 1.1.

But "why" is immaterial ... the restriction is there, and you have to live with it.

I know how to work around it, but from time to time it would be simpler.

You can write this:

AClass[] array;
...
array = new AClass[]{object1, object2};

Look no more for IP addresses not being set in the expected header. Just do the following to inspect the whole server variables and figure out which one is suitable for your case:

print_r($_SERVER);

This link explains how to apply a cell style to a range of cells: http://msdn.microsoft.com/en-us/library/f1hh9fza.aspx

See this snippet:

Microsoft.Office.Tools.Excel.NamedRange rangeStyles =
this.Controls.AddNamedRange(this.Range["A1"], "rangeStyles");

rangeStyles.Value2 = "'Style Test";
rangeStyles.Style = "NewStyle";
rangeStyles.Columns.AutoFit();

I had same problem with 'parallax' plugin. I changed jQuery librery version to *jquery-1.6.4* from *jquery-1.10.2*. And error cleared.

Validating that it is a real email address is much harder.

The regex to confirm the syntax is correct can be very long (see http://www.regular-expressions.info/email.html for example). The best way to confirm an email address is to email the user, and get the user to reply by clicking on a link to validate that they have recieved the email (the way most sign-up systems work).

If push request is shows Rejected, then try first pull from your github account and then try push.

Ex:

In my case it was giving an error-

 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/ashif8984/git-github.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

****So what I did was-****

$ git pull
$ git push

And the code was pushed successfully into my Github Account.

It's just a syntax error, you need parenthesis: (DATETIME('now'))

If you look at the documentation, you'll note the parenthesis that is added around the 'expr' option in the syntax.

The cleanest way I found to do this is create a child of 'ThemeOverlay.AppCompat.Dark.ActionBar'. In the example, I set the Toolbar's background color to RED and text's color to BLUE.

<style name="MyToolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">#FF0000</item>
    <item name="android:textColorPrimary">#0000FF</item>
</style>

You can then apply your theme to the toolbar:

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    app:theme="@style/MyToolbar"
    android:minHeight="?attr/actionBarSize"/>

A regular expression does not account for UTF-8 characters by default. The \s meta-character only accounts for the original latin set. Therefore, the following command only removes tabs, spaces, carriage returns and new lines

// http://stackoverflow.com/a/1279798/54964
$str=preg_replace('/\s+/', '', $str);

With UTF-8 becoming mainstream this expression will more frequently fail/halt when it reaches the new utf-8 characters, leaving white spaces behind that the \s cannot account for.

To deal with the new types of white spaces introduced in unicode/utf-8, a more extensive string is required to match and removed modern white space.

Because regular expressions by default do not recognize multi-byte characters, only a delimited meta string can be used to identify them, to prevent the byte segments from being alters in other utf-8 characters (\x80 in the quad set could replace all \x80 sub-bytes in smart quotes)

$cleanedstr = preg_replace(
    "/(\t|\n|\v|\f|\r| |\xC2\x85|\xc2\xa0|\xe1\xa0\x8e|\xe2\x80[\x80-\x8D]|\xe2\x80\xa8|\xe2\x80\xa9|\xe2\x80\xaF|\xe2\x81\x9f|\xe2\x81\xa0|\xe3\x80\x80|\xef\xbb\xbf)+/",
    "_",
    $str
);

This accounts for and removes tabs, newlines, vertical tabs, formfeeds, carriage returns, spaces, and additionally from here:

nextline, non-breaking spaces, mongolian vowel separator, [en quad, em quad, en space, em space, three-per-em space, four-per-em space, six-per-em space, figure space, punctuation space, thin space, hair space, zero width space, zero width non-joiner, zero width joiner], line separator, paragraph separator, narrow no-break space, medium mathematical space, word joiner, ideographical space, and the zero width non-breaking space.

Many of these wreak havoc in xml files when exported from automated tools or sites which foul up text searches, recognition, and can be pasted invisibly into PHP source code which causes the parser to jump to next command (paragraph and line separators) which causes lines of code to be skipped resulting in intermittent, unexplained errors that we have begun referring to as "textually transmitted diseases"

[Its not safe to copy and paste from the web anymore. Use a character scanner to protect your code. lol]

This is the most native and scalable approach I could find:

>>> myindex = pd.Series(myseries.index, index=myseries)

>>> myindex[7]
3

>>> myindex[[7, 5, 7]]
7    3
5    4
7    3
dtype: int64

It depends on the database you are using. MySQL for example supports the (non-standard) group_concat function. So you could write:

SELECT GROUP_CONCAT(ModuleValue) FROM Table_X WHERE ModuleID=@ModuleID

Group-concat is not available at all database servers though.

For frequent uses of this command I found it easy to add the location of C:\xampp\apache\bin to the PATH. Use whatever directory you have this installed in.

Then you can run from any directory in command line:

httpd -k restart

The answer above that suggests httpd -k -restart is actually a typo. You can see the commands by running httpd /?

It's better to try to simulate a webbrowser by yourself.You don't have to stick with Chrome or IE or else thing.

If you're using Python,you can try package pyQt4 which helps you to simulate a webbrowser. By doing this,there will not be any security reasons and you can set the webbrowser to show in full screen mode automatically.

Recently ran into a problem with this and a Chrome extension that was corrupting a JSON stream when the response header labeled the content-type as 'text/html' apparently extensions can and will use the response header to alter the content prior to further processing by the browser. Changing the content-type fixed the issue.

in terminal do:

vi ~/.bash_profile 

And add this line:

export PATH=${PATH}:/usr/local/mysql/bin

and the type this in terminal:

mysql -u [username] -p [password]

If you don't care about vertex reuse, you could have two output files--one for vertices and one for triangles. Then append the triangle file to the vertex file when you are done.

Date and time as String to Long (millis):

String dateTimeString = "2020-12-12T14:34:18.000Z";

DateTimeFormatter formatter = DateTimeFormatter
                .ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);

LocalDateTime localDateTime = LocalDateTime
        .parse(dateTimeString, formatter);

Long dateTimeMillis = localDateTime
        .atZone(ZoneId.systemDefault())
        .toInstant()
        .toEpochMilli();

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

According to the official docs, browsers do not like it when you use the

Access-Control-Allow-Origin: "*"

header if you're also using the

Access-Control-Allow-Credentials: "true"

header. Instead, they want you to allow their origin specifically. If you still want to allow all origins, you can do some simple Apache magic to get it to work (make sure you have mod_headers enabled):

Header set Access-Control-Allow-Origin "%{HTTP_ORIGIN}e" env=HTTP_ORIGIN

Browsers are required to send the Origin header on all cross-domain requests. The docs specifically state that you need to echo this header back in the Access-Control-Allow-Origin header if you are accepting/planning on accepting the request. That's what this Header directive is doing.

I am working on JUnit in java 8 environment, using jUnit4.12

for me: compiler was not able to find the method assertNotEquals, even when I used
import org.junit.Assert;

So I changed
assertNotEquals("addb", string);
to
Assert.assertNotEquals("addb", string);

So if you are facing problem regarding assertNotEqual not recognized, then change it to Assert.assertNotEquals(,); it should solve your problem

I post the below solution here because after some searching this is where I landed, so other may too. I was trying to use EF 6 to call a stored procedure, but had a similar error because the stored procedure had a linked server being utilized.

The operation could not be performed because OLE DB provider _ for linked server _ was unable to begin a distributed transaction

The partner transaction manager has disabled its support for remote/network transactions*

Jumping over to SQL Client did fix my issue, which also confirmed for me that it was an EF thing.

EF model generated method based attempt:

db.SomeStoredProcedure();

ExecuteSqlCommand based attempt:

db.Database.ExecuteSqlCommand("exec [SomeDB].[dbo].[SomeStoredProcedure]");

With:

var connectionString = db.Database.Connection.ConnectionString;
var connection = new System.Data.SqlClient.SqlConnection(connectionString);    
var cmd = connection.CreateCommand();
cmd.CommandText = "exec [SomeDB].[dbo].[SomeStoredProcedure]";

connection.Open();
var result = cmd.ExecuteNonQuery();

That code can be shortened, but I think that version is slightly more convenient for debugging and stepping through.

I don't believe that Sql Client is necessarily a preferred choice, but I felt this was at least worth sharing if anyone else having similar problems gets landed here by google.

The above Code is C#, but the concept of trying to switch over to Sql Client still applies. At the very least it will be diagnostic to attempt to do so.

On Mac OS X, you can use Ctrl + Fn + F12 to rotate the Android emulator if you have have not configured your keyboard to "Use all F1, F2, etc. keys as standard function keys" (Check it on System Preferences - Keyboard).

If you have checked the option mentioned above, you will not need the Fn key and you should be able to rotate the emulator only with Ctrl + F12.

Change your directive definition from app.module to app.directive. Apart from that everything looks fine. Btw, very rarely do you have to inject a service into a directive. If you are injecting a service ( which usually is a data source or model ) into your directive ( which is kind of part of a view ), you are creating a direct coupling between your view and model. You need to separate them out by wiring them together using a controller.

It does work fine. I am not sure what you are doing which is wrong. Here is a plunk of it working.

Your quotes are in the wrong spot. Here's a simple example:

<div style={{backgroundColor: "#FF0000"}}>red</div>

I've made small modifications to @paul-H code, such that you can set the font size for the x/y axes and legend independently. Hope it helps:

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
x = np.random.normal(size=37)
y = np.random.lognormal(size=37)

# defaults                                                                                                         
sns.set()
fig, ax = plt.subplots()
ax.plot(x, y, marker='s', linestyle='none', label='small')
ax.legend(loc='upper left', fontsize=20,bbox_to_anchor=(0, 1.1))
ax.set_xlabel('X_axi',fontsize=20);
ax.set_ylabel('Y_axis',fontsize=20);

plt.show()

This is the output:

Try this too in addition to MahmoudS comments. Change the maven compiler source and target in your pom.xml to the java version which you are using. Say 1.7 for jdk7

<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>

At runtime, no, you can't.

However via reflection the type parameters are accessible. Try

for(Field field : this.getDeclaredFields()) {
    System.out.println(field.getGenericType())
}

The method getGenericType() returns a Type object. In this case, it will be an instance of ParametrizedType, which in turn has methods getRawType() (which will contain List.class, in this case) and getActualTypeArguments(), which will return an array (in this case, of length one, containing either String.class or Integer.class).

Try with these following examples in this article : http://phpswitch.com/

Possible Switch Cases :

(i). A simple switch statement

The switch statement is wondrous and magic. It's a piece of the language that allows you to select between different options for a value, and run different pieces of code depending on which value is set.

Each possible option is given by a case in the switch statement.

Example :

switch($bar)
{
    case 4:
        echo "This is not the number you're looking for.\n";
        $foo = 92;
}

(ii). Delimiting code blocks

The major caveat of switch is that each case will run on into the next one, unless you stop it with break. If the simple case above is extended to cover case 5:

Example :

case 4:
    echo "This is not the number you're looking for.\n";
    $foo = 92;
    break;

case 5:
    echo "A copy of Ringworld is on its way to you!\n";
    $foo = 34;
    break;

(iii). Using fallthrough for multiple cases

Because switch will keep running code until it finds a break, it's easy enough to take the concept of fallthrough and run the same code for more than one case:

Example :

case 2:

case 3:
case 4:
    echo "This is not the number you're looking for.\n";
    $foo = 92;
    break;

case 5:
    echo "A copy of Ringworld is on its way to you!\n";
    $foo = 34;
    break;

(iv). Advanced switching: Condition cases

PHP's switch doesn't just allow you to switch on the value of a particular variable: you can use any expression as one of the cases, as long as it gives a value for the case to use. As an example, here's a simple validator written using switch:

Example :

switch(true)
{
    case (strlen($foo) > 30):
        $error = "The value provided is too long.";
    $valid = false;
    break;

    case (!preg_match('/^[A-Z0-9]+$/i', $foo)):
        $error = "The value must be alphanumeric.";
    $valid = false;
    break;

    default:
    $valid = true;
    break;
}

i think this may help you to resolve your problem.

You can see the way to change the target on the button OnClick event.

function subm(f,newtarget)
{
document.myform.target = newtarget ;
f.submit();
}

<FORM name="myform" method="post" action="" target="" >

<INPUT type="button" name="Submit" value="Submit" onclick="subm(this.form,'_self');">
<INPUT type="button" name="Submit" value="Submit" onclick="subm(this.form,'_blank');">

Download Google apps (GoogleLoginService.apk , GoogleServicesFramework.apk , Phonesky.apk)
from here.

Start your emulator:

emulator -avd VM_NAME_HERE -partition-size 500 -no-audio -no-boot-anim

Then use the following commands:

# Remount in rw mode.
# NOTE: more recent system.img files are ext4, not yaffs2
adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock0 /system

# Allow writing to app directory on system partition
adb shell chmod 777 /system/app

# Install following apk
adb push GoogleLoginService.apk /system/app/.
adb push GoogleServicesFramework.apk /system/app/.
adb push Phonesky.apk /system/app/. # Vending.apk in older versions
adb shell rm /system/app/SdkSetup*

@Chris Noe

Note that the space in front of the & becomes part of the previous command. That has bitten me with SET, which happily puts trailing blanks into the value.

To get around the trailing-space being added to an environment variable, wrap the set command in parens.

E.g. FOR /F %%I IN ('DIR "*.*" /B /O:D') DO (SET NewestFile=%%I)

Pay attention that in http.Request header "Host" can not be set via Set method

req.Header.Set("Host", "domain.tld")

but can be set directly:

req.Host = "domain.tld":

req, err := http.NewRequest("GET", "http://10.0.0.1/", nil)
if err != nil {
    ...
}

req.Host = "domain.tld"
client := &http.Client{}
resp, err := client.Do(req)

You could just set the width to auto. Then the width of the div will equal 0 if it has no content.

width:auto;

The lmplot function returns a FacetGrid instance. This object has a method called set, to which you can pass key=value pairs and they will be set on each Axes object in the grid.

Secondly, you can set only one side of an Axes limit in matplotlib by passing None for the value you want to remain as the default.

Putting these together, we have:

g = sns.lmplot('X', 'Y', df, col='Z', sharex=False, sharey=False)
g.set(ylim=(0, None))

Recently, I had the same problem within .NET 3.5 (no dynamic available). Here is how I solved:

// pass anonymous object as argument
var args = new { Title = "Find", Type = typeof(FindCondition) };

using (frmFind f = new frmFind(args)) 
{
...
...
}

Adapted from somewhere on stackoverflow:

// Use a custom cast extension
public static T CastTo<T>(this Object x, T targetType)
{
   return (T)x;
}

Now get back the object via cast:

public partial class frmFind: Form
{
    public frmFind(object arguments)
    {

        InitializeComponent();

        var args = arguments.CastTo(new { Title = "", Type = typeof(Nullable) });

        this.Text = args.Title;

        ...
    }
    ...
}

Here are the PHP mail settings I use:

//Mail sending function
$subject = $_POST['name'];
$to = $_POST['email'];
$from = "[email protected]";

//data
$msg = "Your MSG <br>\n";       

//Headers
$headers  = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=UTF-8\r\n";
$headers .= "From: <".$from. ">" ;

mail($to,$subject,$msg,$headers);
echo "Mail Sent.";

With this code you can easily draw a circle... C# is great and easy my friend

public partial class Form1 : Form
{


public Form1()
    {
        InitializeComponent();
    }

  private void button1_Click(object sender, EventArgs e)
    {
        Graphics myGraphics = base.CreateGraphics();
        Pen myPen = new Pen(Color.Red);
        SolidBrush mySolidBrush = new SolidBrush(Color.Red);
        myGraphics.DrawEllipse(myPen, 50, 50, 150, 150);
    }
 }

First, Eloquent automatically converts it's timestamps (created_at, updated_at) into carbon objects. You could just use updated_at to get that nice feature, or specify edited_at in your model in the $dates property:

protected $dates = ['edited_at'];

Now back to your actual question. Carbon has a bunch of comparison functions:

• eq() equals
• ne() not equals
• gt() greater than
• gte() greater than or equals
• lt() less than
• lte() less than or equals

Usage:

if($model->edited_at->gt($model->created_at)){
    // edited at is newer than created at
}

There is no need to add any extra div wrapper as others suggest.

The simplest way is to wrap your input element inside a related label tag and set input style to display:block.

Bonus point earned: now you don't need to set the labels for attribute. Because every label target the nested input.

<form name="message" method="post">
    <section>
        <label class="left">
            Name
            <input id="name" type="text" name="name">
        </label>
        <label class="right">
            Email
            <input id="email" type="text" name="email">
        </label>
    </section>
</form>

I have answered a similar question here.

I know you have already said position: absolute; is inconvenient, but it works. See below for further information on fixing the resize issue.

Also see this jsFiddle for a demo, although I have only added WebKit prefixes so open in Chrome.

You basically have two issues which I will deal with separately.

1. Getting the child of a flex-item to fill height 100%

• Set position: relative; on the parent of the child.
• Set position: absolute; on the child.
• You can then set width/height as required (100% in my sample).

2. Fixing the resize scrolling "quirk" in Chrome

• Put overflow-y: auto; on the scrollable div.
• The scrollable div must have an explicit height specified. My sample already has height 100%, but if none is already applied you can specify height: 0;

See this answer for more information on the scrolling issue.

Sure you can use Swift!

1. Adding the video file

Add the video (lets call it video.m4v) to your Xcode project

2. Checking your video is into the Bundle

Open the Project Navigator cmd + 1

Then select your project root > your Target > Build Phases > Copy Bundle Resources.

Your video MUST be here. If it's not, then you should add it using the plus button

3. Code

Open your View Controller and write this code.

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        playVideo()
    }

    private func playVideo() {
        guard let path = Bundle.main.path(forResource: "video", ofType:"m4v") else {
            debugPrint("video.m4v not found")
            return
        }
        let player = AVPlayer(url: URL(fileURLWithPath: path))
        let playerController = AVPlayerViewController()
        playerController.player = player
        present(playerController, animated: true) {
            player.play()
        }
    }
}

With Bootstrap 4 .hidden-* classes were completely removed (yes, they were replaced by hidden-*-* but those classes are also gone from v4 alphas).

Starting with v4-beta, you can combine .d-*-none and .d-*-block classes to achieve the same result.

visible-* was removed as well; instead of using explicit .visible-* classes, make the element visible by not hiding it (again, use combinations of .d-none .d-md-block). Here is the working example:

<div class="col d-none d-sm-block">
    <span class="vcard">
        …
    </span>
</div>
<div class="col d-none d-xl-block">
    <div class="d-none d-md-block">
                …
    </div>
    <div class="d-none d-sm-block">
                …
    </div>
</div>

class="hidden-xs" becomes class="d-none d-sm-block" (or d-none d-sm-inline-block) ...

<span class="d-none d-sm-inline">hidden-xs</span>

<span class="d-none d-sm-inline-block">hidden-xs</span>

An example of Bootstrap 4 responsive utilities:

<div class="d-none d-sm-block"> hidden-xs           
  <div class="d-none d-md-block"> visible-md and up (hidden-sm and down)
    <div class="d-none d-lg-block"> visible-lg and up  (hidden-md and down)
      <div class="d-none d-xl-block"> visible-xl </div>
    </div>
  </div>
</div>

<div class="d-sm-none"> eXtra Small <576px </div>
<div class="d-none d-sm-block d-md-none d-lg-none d-xl-none"> SMall =576px </div>
<div class="d-none d-md-block d-lg-none d-xl-none"> MeDium =768px </div>
<div class="d-none d-lg-block d-xl-none"> LarGe =992px </div>
<div class="d-none d-xl-block"> eXtra Large =1200px </div>

<div class="d-xl-none"> hidden-xl (visible-lg and down)         
  <div class="d-lg-none d-xl-none"> visible-md and down (hidden-lg and up)
    <div class="d-md-none d-lg-none d-xl-none"> visible-sm and down  (or hidden-md and up)
      <div class="d-sm-none"> visible-xs </div>
    </div>
  </div>
</div>

Application pools are used to separate sets of IIS worker processes that share the same configuration and application boundaries.

Application pools used to isolate our web application for better security, reliability, and availability and performance and keep running without impacting each other . The worker process serves as the process boundary that separates each application pool so that when one worker process or application is having an issue or recycles, other applications or worker processes are not affected. One Application Pool can have multiple worker process Also.

Or we can simply say that, An application pool is a group of one or more URLs that are served by a worker process or set of worker processes. Any Web directory or virtual directory can be assigned to an application pool. So that one website cannot be affected by other, if u used separated application pool.

You need to pass a function to setTimeout

$(window).load(function () {
    window.setTimeout(function () {
        window.location.href = "https://www.google.co.in";
    }, 5000)
});

To support delta

const range = (start, end, delta) => {
  return Array.from(
    {length: (end - start) / delta}, (v, k) => (k * delta) + start
  )
};

Most Secure Solution, JS only

As mentioned by alko989, there is a major security flaw with _blank (details here).

To avoid it from pure JS code:

const openInNewTab = (url) => {
  const newWindow = window.open(url, '_blank', 'noopener,noreferrer')
  if (newWindow) newWindow.opener = null
}

Then add to your onClick

onClick={() => openInNewTab('https://stackoverflow.com')}

The third param can also take these optional values, based on your needs.

If you want to go even further than @tetra with ES6 you can use the Object spread syntax and do something like this:

let john = {
    firstName: "John",
    lastName: "Doe",
};

let people = new Array(10).fill().map((e, i) => {(...john, id: i});

Synchronized Vs Atomic Vs Volatile:

• Volatile and Atomic is apply only on variable , While Synchronized apply on method.
• Volatile ensure about visibility not atomicity/consistency of object , While other both ensure about visibility and atomicity.
• Volatile variable store in RAM and it’s faster in access but we can’t achive Thread safety or synchronization whitout synchronized keyword.
• Synchronized implemented as synchronized block or synchronized method while both not. We can thread safe multiple line of code with help of synchronized keyword while with both we can’t achieve the same.
• Synchronized can lock the same class object or different class object while both can’t.

Please correct me if anything i missed.

If you want to keep it simple go ahead and try this out.

$page_number = mysqli_escape_string($con, $_GET['page']);
$count_per_page = 20;
$next_offset = $page_number * $count_per_page;
$cat =mysqli_query($con, "SELECT * FROM categories LIMIT $count_per_page OFFSET $next_offset");
while ($row = mysqli_fetch_array($cat))
        $count = $row[0];

The rest is up to you. If you have result comming from two tables i suggest you try a different approach.

Mr. Curious was curious about this as well. In addition to the #>> '{}' operator, in 9.6+ one can get the value of a jsonb string with the ->> operator:

select to_jsonb('Some "text"'::TEXT)->>0;
  ?column?
-------------
 Some "text"
(1 row)

If one has a json value, then the solution is to cast into jsonb first:

select to_json('Some "text"'::TEXT)::jsonb->>0;
  ?column?
-------------
 Some "text"
(1 row)

Turns out that I had this problem and it was because I used "tabs" to indent lines instead of spaces. Just posting, in case it helps anyone.

Hi I faced the same issue in VS2008, I tried based on the post 8 (Thanks to the "Tricky part" section in that)

The (Ctrl+Alt+D) combo did not work there in VS2008, but after opening the Report file(rdlc) I browsed on the View menu and found out that View->Toolbars->Data Design is the solution for that.

Upon opening that we get around 4 icons of which the "Show Data Sources" section brings the "Website Data Sources" section which fetches all Entities, Typed DataSets etc.

The keybord shortcut is (Shift+Alt+D).

The twisty part here is the "Data Sources" section available with the Server Explorer toolbar doesnt bring up any stuff but the "Website Data Sources" brings all the needed., can somebody explain that to me.
