Programs & Examples On #Prettyfaces

6 years late to the party but I've been searching for how to extract an html element's tag attribute value, so for:

<span property="addressLocality">Ayr</span>

I want "addressLocality". I kept being directed back here, but the answers didn't really solve my problem.

How I managed to do it eventually:

>>> from bs4 import BeautifulSoup as bs

>>> soup = bs('<span property="addressLocality">Ayr</span>', 'html.parser')
>>> my_attributes = soup.find().attrs
>>> my_attributes
{u'property': u'addressLocality'}

As it's a dict, you can then also use keys and 'values'

>>> my_attributes.keys()
[u'property']
>>> my_attributes.values()
[u'addressLocality']

Hopefully it helps someone else!

Add '.ToString' to improve comparing on ASP.NET MVC

If it's not important to use a RelativeLayout, you could use a LinearLayout, and do this:

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

Doing this allows you to avoid the addRule method you've tried. You can simply use addView() to add new TextViews.

Complete code:

String[] textArray = {"One", "Two", "Three", "Four"};
LinearLayout linearLayout = new LinearLayout(this);
setContentView(linearLayout);
linearLayout.setOrientation(LinearLayout.VERTICAL);        
for( int i = 0; i < textArray.length; i++ )
{
    TextView textView = new TextView(this);
    textView.setText(textArray[i]);
    linearLayout.addView(textView);
}

I use to have that problem, but the simples way to fix it is this (this works for me):

on the CSS file type:

body{overflow-y:scroll;}

as that simple! :)

If you are looking for a functional approach:

var obj = {1: 11, 2: 22};
var arr = Object.keys(obj).map(function (key) { return obj[key]; });

Results in:

[11, 22]

The same with an ES6 arrow function:

Object.keys(obj).map(key => obj[key])

With ES7 you will be able to use Object.values instead (more information):

var arr = Object.values(obj);

Or if you are already using Underscore/Lo-Dash:

var arr = _.values(obj)

For the beginners:

Null coalescing operator (??)

Everything is true except null values and undefined (variable/array index/object attributes)

ex:

$array = [];
$object = new stdClass();

var_export (false ?? 'second');                           # false
var_export (true  ?? 'second');                           # true
var_export (null  ?? 'second');                           # 'second'
var_export (''    ?? 'second');                           # ""
var_export ('some text'    ?? 'second');                  # "some text"
var_export (0     ?? 'second');                           # 0
var_export ($undefinedVarible ?? 'second');               # "second"
var_export ($array['undefined_index'] ?? 'second');       # "second"
var_export ($object->undefinedAttribute ?? 'second');     # "second"

this is basically check the variable(array index, object attribute.. etc) is exist and not null. similar to isset function

Ternary operator shorthand (?:)

every false things (false,null,0,empty string) are come as false, but if it's a undefined it also come as false but Notice will throw

ex

$array = [];
$object = new stdClass();

var_export (false ?: 'second');                           # "second"
var_export (true  ?: 'second');                           # true
var_export (null  ?: 'second');                           # "second"
var_export (''    ?: 'second');                           # "second"
var_export ('some text'    ?? 'second');                  # "some text"
var_export (0     ?: 'second');                           # "second"
var_export ($undefinedVarible ?: 'second');               # "second" Notice: Undefined variable: ..
var_export ($array['undefined_index'] ?: 'second');       # "second" Notice: Undefined index: ..
var_export ($object->undefinedAttribute ?: 'second');     # "Notice: Undefined index: ..

Hope this helps

Ok, for me that work with this...

var e2key = function(e) {
    if (!e) return '';
    var event2key = {
        '96':'0', '97':'1', '98':'2', '99':'3', '100':'4', '101':'5', '102':'6', '103':'7', '104':'8', '105':'9', // Chiffres clavier num
        '48':'m0', '49':'m1', '50':'m2', '51':'m3', '52':'m4', '53':'m5', '54':'m6', '55':'m7', '56':'m8', '57':'m9', // Chiffres caracteres speciaux
        '65':'a', '66':'b', '67':'c', '68':'d', '69':'e', '70':'f', '71':'g', '72':'h', '73':'i', '74':'j', '75':'k', '76':'l', '77':'m', '78':'n', '79':'o', '80':'p', '81':'q', '82':'r', '83':'s', '84':'t', '85':'u', '86':'v', '87':'w', '88':'x', '89':'y', '90':'z', // Alphabet
        '37':'left', '39':'right', '38':'up', '40':'down', '13':'enter', '27':'esc', '32':'space', '107':'+', '109':'-', '33':'pageUp', '34':'pageDown' // KEYCODES
    };
    return event2key[(e.which || e.keyCode)];
};

var page5Key = function(e, customKey) {
    if (e) e.preventDefault();
    switch(e2key(customKey || e)) {
        case 'left': /*...*/ break;
        case 'right': /*...*/ break;
    }
};

$(document).bind('keyup', page5Key);

$(document).trigger('keyup', [{preventDefault:function(){},keyCode:37}]); 

Quoted from this post:

The question is about how to make CTRL+SHIFT+U work in Visual Studio Code. Here is how to do it. (Version 1.8.1 or above). You can also choose a different key combination.

File-> Preferences -> Keyboard Shortcuts.

An editor will appear with keybindings.json file. Place the following JSON in there and save.

[
 {
    "key": "ctrl+shift+u",
    "command": "editor.action.transformToUppercase",
    "when": "editorTextFocus"
 },
 {
    "key": "ctrl+shift+l",
    "command": "editor.action.transformToLowercase",
    "when": "editorTextFocus"
 }
]

Now CTRL+SHIFT+U will capitalise selected text, even if multi line. In the same way, CTRL+SHIFT+L will make selected text lowercase.

These commands are built into VS Code, and no extensions are required to make them work.

I formerly voted to close this question as off-topic but actually I changed my mind as this is quite nice visual effect which, unfortunately, is not yet part of support library. It will most likely show up in future update, but there's no time frame announced.

Luckily there are few custom implementations already available:

• https://github.com/traex/RippleEffect
• https://github.com/balysv/material-ripple
• https://github.com/siriscac/RippleView
• https://github.com/ozodrukh/RippleDrawable

including Materlial themed widget sets compatible with older versions of Android:

• https://github.com/keithellis/MaterialWidget

so you can try one of these or google for other "material widgets" or so...

Referring to the answers above, I am only adding this to help clarify things. It is possible to use HttpClient from .Net 4.0, and you have to install the package from here

However, the text is very confusion and contradicts itself.

This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, or Windows Phone 8.1 when consuming a library that uses this package.

But underneath it states that these are the supported platforms.

Supported Platforms:

• .NET Framework 4

• Windows 8

• Windows Phone 8.1

• Windows Phone Silverlight 7.5

• Silverlight 4

• Portable Class Libraries

Ignore what it ways about targeting .Net 4.5. This is wrong. The package is all about using HttpClient in .Net 4.0. However, you may need to use VS2012 or higher. Not sure if it works in VS2010, but that may be worth testing.

You should use static String.Compare function like following

x => String.Compare (x.Username, (string)drUser["Username"],
                     StringComparison.OrdinalIgnoreCase) == 0

Html a tag

Link in html

 <a href="index1.php">page1</a>
 <a href="page2.php">page2</a>

Html in php

echo ' <a href="index1.php">page1</a>';
echo '<a href="page2.php">page2</a>';

Use it to achieve what you want. Then decide which properties you want to return.

yourList.OrderBy(l => l.Id).GroupBy(l => new { GroupName = l.F1}).Select(r => r.Key.GroupName)

The second loop involves a lot less cache activity, so it's easier for the processor to keep up with the memory demands.

You can do it pretty easy in Interface Builder. Just create a view with a table and drop another view onto the table. This will become the table header view. Add your labels and image to that view. See the pic below for the view hierarchy.

Thats work for me:

var jsScripts = [];

jsScripts.push("/js/script1.js" );
jsScripts.push("/js/script2.js" );
jsScripts.push("/js/script3.js" );

$(jsScripts).each(function( index, value ) {
    $.holdReady( true );
    $.getScript( value ).done(function(script, status) {
        console.log('Loaded ' + index + ' : ' + value + ' (' + status + ')');                
        $.holdReady( false );
    });
});

The terms "shallow copy" and "deep copy" are a bit vague; I would suggest using the terms "memberwise clone" and what I would call a "semantic clone". A "memberwise clone" of an object is a new object, of the same run-time type as the original, for every field, the system effectively performs "newObject.field = oldObject.field". The base Object.Clone() performs a memberwise clone; memberwise cloning is generally the right starting point for cloning an object, but in most cases some "fixup work" will be required following a memberwise clone. In many cases attempting to use an object produced via memberwise clone without first performing the necessary fixup will cause bad things to happen, including the corruption of the object that was cloned and possibly other objects as well. Some people use the term "shallow cloning" to refer to memberwise cloning, but that's not the only use of the term.

A "semantic clone" is an object which is contains the same data as the original, from the point of view of the type. For examine, consider a BigList which contains an Array> and a count. A semantic-level clone of such an object would perform a memberwise clone, then replace the Array> with a new array, create new nested arrays, and copy all of the T's from the original arrays to the new ones. It would not attempt any sort of deep-cloning of the T's themselves. Ironically, some people refer to the of cloning "shallow cloning", while others call it "deep cloning". Not exactly useful terminology.

While there are cases where truly deep cloning (recursively copying all mutable types) is useful, it should only be performed by types whose constituents are designed for such an architecture. In many cases, truly deep cloning is excessive, and it may interfere with situations where what's needed is in fact an object whose visible contents refer to the same objects as another (i.e. a semantic-level copy). In cases where the visible contents of an object are recursively derived from other objects, a semantic-level clone would imply a recursive deep clone, but in cases where the visible contents are just some generic type, code shouldn't blindly deep-clone everything that looks like it might possibly be deep-clone-able.

You may want to create a subRepeater.

<asp:Repeater ID="SubRepeater" runat="server" DataSource='<%# Eval("Fields") %>'>
  <ItemTemplate>
    <span><%# Eval("Name") %></span>
  </ItemTemplate>
</asp:Repeater>

You can also cast your fields

<%# ((ArrayFields)Container.DataItem).Fields[0].Name %>

Finally you could do a little CSV Function and write out your fields with a function

<%# GetAsCsv(((ArrayFields)Container.DataItem).Fields) %>

public string GetAsCsv(IEnumerable<Fields> fields)
{
  var builder = new StringBuilder();
  foreach(var f in fields)
  {
    builder.Append(f);
    builder.Append(",");
  }
  builder.Remove(builder.Length - 1);
  return builder.ToString();
}

UNMET PEER DEPENDENCY error is thrown when the dependencies of one or more modules specified in the package.json file is not met. Check the warnings carefully and update the package.json file with correct versions of dependencies.

Then run

rm -rf node_modules/
npm cache clean
npm install

This will install all the required dependencies correctly.

You're likely not in the node directory. Try switching to the directory that you unpacked node to and try running the command there.

The distinction between TO, CC and BCC occurs only in the text headers. At the SMTP level, everybody is a recipient.

TO - There is a TO: header with this recipient's address

CC - There is a CC: header with this recipient's address

BCC - This recipient isn't mentioned in the headers at all, but is still a recipient.

If you have

TO: [email protected]
CC: [email protected]
BCC: [email protected]

You have three recipients. The headers in the email body will include only the TO: and CC:

(eg: div,footer,table) Right click -> Edit as HTML

Then you can copy and paster wherever you need...

that's all enjoy your coding.....

jQuery API specifically says not to bind to beforeunload, and instead should bind directly to the window.onbeforeunload, I just ran across a pretty bad memory in part due binding to beforeunload with jQuery.

try this, MYJSON will be your json data.

var mytky=[];
mytky=DistinctRecords(MYJSON,"mykeyname");

function DistinctRecords(MYJSON,prop) {
  return MYJSON.filter((obj, pos, arr) => {
    return arr.map(mapObj => mapObj[prop]).indexOf(obj[prop]) === pos;
 })
}

This Python snippet will git mv --force all files in a directory to be lowercase. For example, foo/Bar.js will become foo/bar.js via git mv foo/Bar.js foo/bar.js --force.

Modify it to your liking. I just figured I'd share :)

import os
import re

searchDir = 'c:/someRepo'
exclude = ['.git', 'node_modules','bin']
os.chdir(searchDir)

for root, dirs, files in os.walk(searchDir):
    dirs[:] = [d for d in dirs if d not in exclude]
    for f in files:
        if re.match(r'[A-Z]', f):
            fullPath = os.path.join(root, f)
            fullPathLower = os.path.join(root, f[0].lower() + f[1:])
            command = 'git mv --force ' + fullPath + ' ' + fullPathLower
            print(command)
            os.system(command)

I'm guessing your code failed BEFORE import sys, so it can't find it when you handle the exception.

Also, you should indent the your code whithin the try block.

try:

import sys
# .. other safe imports
try:
    import numpy as np
    # other unsafe imports
except ImportError:
    print "Error: missing one of the libraries (numpy, pyfits, scipy, matplotlib)"
    sys.exit()

Try SilentCMD. This is a small freeware program that executes a batch file without displaying the command prompt window.

Faced same kind of problem and now clearly understood how both will works.Hope this reference link will be helpful...

Async

When you add the async attribute to your script tag, the fol­low­ing will happen.

<script src="myfile1.js" async></script>
<script src="myfile2.js" async></script>

1. Make par­al­lel requests to fetch the files.
2. Con­tinue pars­ing the doc­u­ment as if it was never interrupted.
3. Exe­cute the indi­vid­ual scripts the moment the files are downloaded.

Defer

Defer is very sim­i­lar to async with one major dif­fer­er­ence. Here’s what hap­pens when a browser encoun­ters a script with the defer attribute.

<script src="myfile1.js" defer></script>
<script src="myfile2.js" defer></script>

1. Make par­al­lel requests to fetch the indi­vid­ual files.
2. Con­tinue pars­ing the doc­u­ment as if it was never interrupted.
3. Fin­ish pars­ing the doc­u­ment even if the script files have downloaded.
4. Exe­cute each script in the order they were encoun­tered in the document.

how can I fill a multidimensional array in Java without using a loop?

Multidimensional arrays are just arrays of arrays and fill(...) doesn't check the type of the array and the value you pass in (this responsibility is upon the developer).

Thus you can't fill a multidimensional array reasonably well without using a loop.

Be aware of the fact that, unlike languages like C or C++, Java arrays are objects and in multidimensional arrays all but the last level contain references to other Array objects. I'm not 100% sure about this, but most likely they are distributed in memory, thus you can't just fill a contiguous block without a loop, like C/C++ would allow you to do.

Python opens files almost in the same way as in C:

• r+ Open for reading and writing. The stream is positioned at the beginning of the file.

• a+ Open for reading and appending (writing at end of file). The file is created if it does not exist. The initial file position for reading is at the beginning of the file, but output is appended to the end of the file (but in some Unix systems regardless of the current seek position).

One of The Shortest method i found for single value while i was searching for myself, is just passing single string and setting string as model in view like this.

In your Partial calling side

@Html.Partial("ParitalAction", "String data to pass to partial")

And then binding the model with Partial View like this

@model string

and the using its value in Partial View like this

@Model

You can also play with other datatypes like array, int or more complex data types like IDictionary or something else.

Hope it helps,

In CSS3 you have:

:nth-last-child(2)

See: https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-last-child

nth-last-child Browser Support:

• Chrome 2
• Firefox 3.5
• Opera 9.5, 10
• Safari 3.1, 4
• Internet Explorer 9

Because it's not supported and why would you want a goto keyword that did nothing or a variable named goto?

Although you can use break label; and continue label; statements to effectively do what goto does. But I wouldn't recommend it.

public static void main(String [] args) {

     boolean t = true;

     first: {
        second: {
           third: {
               System.out.println("Before the break");

               if (t) {
                  break second;
               }

               System.out.println("Not executed");
           }

           System.out.println("Not executed - end of second block");
        }

        System.out.println("End of third block");
     }
}

If you are using a List<Object> to hold objects of a subtype that has a name field (lets call the subtype NamedObject), you'll need to downcast the list elements in order to access the name. You have 3 options, the best of which is the first:

1. Don't use a List<Object> in the first place if you can help it - keep your named objects in a List<NamedObject>
2. Copy your List<Object> elements into a List<NamedObject>, downcasting in the process, do the sort, then copy them back
3. Do the downcasting in the Comparator

Option 3 would look like this:

Collections.sort(p, new Comparator<Object> () {
        int compare (final Object a, final Object b) {
                return ((NamedObject) a).getName().compareTo((NamedObject b).getName());
        }
}

Beware the leading 00 that can appear in the modulus when using:

openssl rsa -pubin -inform PEM -text -noout < public.key

The example modulus contains 257 bytes rather than 256 bytes because of that 00, which is included because the 9 in 98 looks like a negative signed number.

The 3 easiest ways IMHO are

1: you create an image of a button and put a href around it. (Not a good way, you lose flexibility and will provide a lot of difficulties and problems.)

2 (The easiest one) -> JQuery

<input type="submit" someattribute="http://yoururl/index.php">

  $('button[type=submit] .default').click(function(){
     window.location = $(this).attr("someattribute");
     return false; //otherwise it will send a button submit to the server

   });  

3 (also easy but I prefer previous one):

<INPUT TYPE=BUTTON OnClick="somefunction("http://yoururl");return false" VALUE="somevalue">

$fn.somefunction= function(url) {
    window.location = url;
};

You probably need to some plugin like Jquery multiselect dropdown. Here is a demo.

Also you need to close your option tags like this:

<select name="test" multiple>
    <option>123</option>
    <option>456</option>
    <option>789</option>
</select>

JSFIDDLE DEMO

I'd recommend looking at consistent gets/logical reads as a better proxy for 'work' than run time. The run time can be skewed by what else is happening on the database server, how much stuff is in the cache etc.

But if you REALLY want SQL executing time, the V$SQL view has both CPU_TIME and ELAPSED_TIME.

I think the quick and dirty answer is that

• LINQ to SQL is the quick-and-easy way to do it. This means you will get going quicker, and deliver quicker if you are working on something smaller.
• Entity Framework is the all-out, no-holds-barred way to do it. This means you will take more time up-front, develop slower, and have more flexibility if you are working on something larger.

Use onkeyup on the text box and check the keycode of the key pressed, if its between 65 and 90, allow else empty the text box.

@Tama, you may want to check this answer: Using Font Awesome icons as bullets

Basically you can accomplish this by using only CSS without the need for the extra markup as suggested by FontAwesome and the other answers here.

In other words, you can accomplish what you need using the same basic markup you mentioned in your initial post:

<ul>
  <li>...</li>
  <li>...</li>
  <li>...</li>
</ul>

Thanks.

For swift

var label = UILabel(frame: CGRect(x: 0, y: 0, width: 250, height: 50))
label.textAlignment = .left
label.text = "This is a Label"
self.view.addSubview(label)

It seems if your key is saved in a variable. data.key = value won't work.

You should use data[key] = value

Example:

data = {key1:'v1', key2:'v2'};

var mykey = 'key1'; 
data.mykey = 'newv1';
data[mykey] = 'newV2';

console.log(data);

Result:

{
  "key1": "newV2",
  "key2": "v2",
  "mykey": "newv1"
}

I know it doesn't explain the meaning but I've made myself a little image, as reference to remind which one to use:

Hope it helps!

PS - Give a check also to the link in Nitay's answer

You can create any kind of your own assertions based on assertions from junit:

static void assertDoesNotThrow(Executable executable) {
    assertDoesNotThrow(executable, "must not throw");
}
static void assertDoesNotThrow(Executable executable, String message) {
    try {
        executable.execute();
    } catch (Throwable err) {
        fail(message);
    }
}

And test:

//the following will succeed
assertDoesNotThrow(()->methodMustNotThrow(1));
assertDoesNotThrow(()->methodMustNotThrow(1), "fail with specific message: facepalm");
//the following will fail
assertDoesNotThrow(()->methodMustNotThrow(2));
assertDoesNotThrow(()-> {throw new Exception("Hello world");}, "Fail: must not trow");

Generally speaking there is possibility to instantly fail("bla bla bla") the test in any scenarios, in any place where it makes sense. For instance use it in a try/catch block to fail if anything is thrown in the test case:

try{methodMustNotThrow(1);}catch(Throwable e){fail("must not throw");}
//or
try{methodMustNotThrow(1);}catch(Throwable e){Assertions.fail("must not throw");}

This is the sample of the method we test, supposing we have such a method that must not fail under specific circumstances, but it can fail:

void methodMustNotThrow(int x) throws Exception{
    if (x == 1) return;
    throw new Exception();
}

The above method is a simple sample. But this works for complex situations, where the failure is not so obvious. There are the imports:

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.function.Executable;
import static org.junit.jupiter.api.Assertions.*;

If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).

Eclipse Classic is basically the full featured Eclipse without the Java EE part.

I found out why this happening.

After looking at my settings on my wamp, i did not check http headers, since activated this, it now works.

Thank you everyone for trying to solve this. :)

I had this issue - across iOS & Android, developing on Mac - after I had been fiddling with a dependency's code in the node_modules dir.

I solved it with:

rm -rf node_modules
npm i
npx pod-install ios

Which basically just re-installs your dependencies fresh.

First of all you use here two strings: "" marks a string it may be ""-empty "s"- string of lenght 1 or "aaa" string of lenght 3, while '' marks chars . In order to be able to do String str = "a" + "aaa" + 'a' you must use method Character.toString(char c) as @Thomas Keene said so an example would be String str = "a" + "aaa" + Character.toString('a')

df.select_dtypes(exclude = ['object'])

Update:

df.select_dtypes(include= np.number)

or with new version of panda

 df.select_dtypes('number')

Python has a built in any() function for exactly this purpose.

My answer provides a ways to run a subset of test in different scenarios.

Run all tests in a project

pytest

Run tests in a Single Directory

To run all the tests from one directory, use the directory as a parameter to pytest:

pytest tests/my-directory

Run tests in a Single Test File/Module

To run a file full of tests, list the file with the relative path as a parameter to pytest:

pytest tests/my-directory/test_demo.py

Run a Single Test Function

To run a single test function, add :: and the test function name:

pytest -v tests/my-directory/test_demo.py::test_specific_function

-v is used so you can see which function was run.

Run a Single Test Class

To run just a class, do like we did with functions and add ::, then the class name to the file parameter:

pytest -v tests/my-directory/test_demo.py::TestClassName

Run a Single Test Method of a Test Class

If you don't want to run all of a test class, just one method, just add another :: and the method name:

pytest -v tests/my-directory/test_demo.py::TestClassName::test_specific_method

Run a Set of Tests Based on Test Name

The -k option enables you to pass in an expression to run tests that have certain names specified by the expression as a substring of the test name. It is possible to use and, or, and not to create complex expressions.

For example, to run all of the functions that have _raises in their name:

pytest -v -k _raises

I suggest pyPdf. It works really nice. I also wrote a blog post some while ago, you can find it here.

In order to send data from child component create property decorated with output() in child component and in the parent listen to the created event. Emit this event with new values in the payload when ever it needed.

@Output() public eventName:EventEmitter = new EventEmitter();

to emit this event:

this.eventName.emit(payloadDataObject);

You can use request.build_absolute_uri()

By default, it will return a full path.

But if you pass in a parameter like this:

request.build_absolute_uri('/')

This would return the domain name.

Similarities between XSD and DTD

both specify elements, attributes, nesting, ordering, #occurences

Differences between XSD and DTD

XSD also has data types, (typed) pointers, namespaces, keys and more.... unlike DTD 

Moreover though XSD is little verbose its syntax is extension of XML, making it convenient to learn fast.

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

See Heroku “psql: FATAL: remaining connection slots are reserved for non-replication superuser connections”:

Heroku sometimes has a problem with database load balancing.

André Laszlo, markshiz and me all reported dealing with that in comments on the question.

To save you the support call, here's the response I got from Heroku Support for a similar issue:

Hello,

One of the limitations of the hobby tier databases is unannounced maintenance. Many hobby databases run on a single shared server, and we will occasionally need to restart that server for hardware maintenance purposes, or migrate databases to another server for load balancing. When that happens, you'll see an error in your logs or have problems connecting. If the server is restarting, it might take 15 minutes or more for the database to come back online.

Most apps that maintain a connection pool (like ActiveRecord in Rails) can just open a new connection to the database. However, in some cases an app won't be able to reconnect. If that happens, you can heroku restart your app to bring it back online.

This is one of the reasons we recommend against running hobby databases for critical production applications. Standard and Premium databases include notifications for downtime events, and are much more performant and stable in general. You can use pg:copy to migrate to a standard or premium plan.

If this continues, you can try provisioning a new database (on a different server) with heroku addons:add, then use pg:copy to move the data. Keep in mind that hobby tier rules apply to the $9 basic plan as well as the free database.

Thanks, Bradley

Altova XmlSpy does this well - you can find an overview here

If you specifically don't want to compare contents of files and only check which one are not present in both of the directories, you can compare lists of files, generated by another command.

diff <(find DIR1 -printf '%P\n' | sort) <(find DIR2 -printf '%P\n' | sort) | grep '^[<>]'

-printf '%P\n' tells find to not prefix output paths with the root directory.

I've also added sort to make sure the order of files will be the same in both calls of find.

The grep at the end removes information about identical input lines.

It's worth mentioning that you may have been able to read this in directly e.g. if you were using read_csv using parse_dates=[['Date', 'Time']].

Assuming these are just strings you could simply add them together (with a space), allowing you to apply to_datetime:

In [11]: df['Date'] + ' ' + df['Time']
Out[11]:
0    01-06-2013 23:00:00
1    02-06-2013 01:00:00
2    02-06-2013 21:00:00
3    02-06-2013 22:00:00
4    02-06-2013 23:00:00
5    03-06-2013 01:00:00
6    03-06-2013 21:00:00
7    03-06-2013 22:00:00
8    03-06-2013 23:00:00
9    04-06-2013 01:00:00
dtype: object

In [12]: pd.to_datetime(df['Date'] + ' ' + df['Time'])
Out[12]:
0   2013-01-06 23:00:00
1   2013-02-06 01:00:00
2   2013-02-06 21:00:00
3   2013-02-06 22:00:00
4   2013-02-06 23:00:00
5   2013-03-06 01:00:00
6   2013-03-06 21:00:00
7   2013-03-06 22:00:00
8   2013-03-06 23:00:00
9   2013-04-06 01:00:00
dtype: datetime64[ns]

Note: surprisingly (for me), this works fine with NaNs being converted to NaT, but it is worth worrying that the conversion (perhaps using the raise argument).

I have a Web Application with several other referenced Projects in the Solution. I've deployed successfully with a single Publish configuration many times in the past. I changed the Project Configuration from Debug to Release for a Project that had been missed in the past. The next time I attempted to deploy I got these symptoms, where the Publish just quietly fails - it does nothing and says it succeeded:

1>------ Build started: Project: Project, Configuration: DeployProduction Any CPU ------
1>  
2>Publishing folder /...
========== Build: 1 succeeded, 0 failed, 9 up-to-date, 0 skipped ==========
========== Publish: 1 succeeded, 0 failed, 0 skipped ==========

The only way to recover it was to wipe out the Publish profile, close Visual Studio to force it to save the deletion, reopen it, and recreate the Publish profile from scratch. Once I did that I could Publish fine again.

Just tell request that you are using json:true and forget about header and parse

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'GET',
    json:true
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

and the same for post

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'POST',
    json: {"name":"John", "lastname":"Doe"}
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

If anyone else stumbles onto this page from google like I did:

use putty (putty.exe) to sign into your server and install curl using this command :

    sudo apt-get install php5-curl

Make sure curl is enabled in the php.ini file. For me it's in /etc/php5/apache2/php.ini, if you can't find it, this line might be in /etc/php5/conf.d/curl.ini. Make sure the line :

    extension=curl.so

is not commented out then restart apache, so type this into putty:

    sudo /etc/init.d/apache2 restart

Info for install from https://askubuntu.com/questions/9293/how-do-i-install-curl-in-php5, to check if it works this stack overflow might help you: Detect if cURL works?

You need use JSON.parse() for convert String into a Object:

var obj = JSON.parse('{ "firstName":"name1", "lastName": "last1" }');

I think several of the answers hit around the possible solution to your problem.

I agree the easiest (and best solution for SEO purposes) is the 301 redirect. In IIS this is fairly trivial, you'd create a site for subdomain.hostone.com, after creating the site, right-click on the site and go into properties. Click on the "Home Directory" tab of the site properties window that opens. Select the radio button "A redirection to a URL", enter the url for the new site (http://subdomain.hosttwo.com), and check the checkboxes for "The exact URL entered above", "A permanent redirection for this resource" (this second checkbox causes a 301 redirect, instead of a 302 redirect). Click OK, and you're done.

Or you could create a page on the site of http://subdomain.hostone.com, using one of the following methods (depending on what the hosting platform supports)

PHP Redirect:

<?
Header( "HTTP/1.1 301 Moved Permanently" ); 
Header( "Location: http://subdomain.hosttwo.com" ); 
?>

ASP Redirect:

<%@ Language=VBScript %>
<%
Response.Status="301 Moved Permanently"
Response.AddHeader "Location","http://subdomain.hosttwo.com"
%>

ASP .NET Redirect:

<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location","http://subdomain.hosttwo.com");
}
</script>

Now assuming your CNAME record is correctly created, then the only problem you are experiencing is that the site created for http://subdomain.hosttwo.com is using a shared IP, and host headers to determine which site should be displayed. To resolve this issue under IIS, in IIS Manager on the web server, you'd right-click on the site for subdomain.hosttwo.com, and click "Properties". On the displayed "Web Site" tab, you should see an "Advanced" button next to the IP address that you'll need to click. On the "Advanced Web Site Identification" window that appears, click "Add". Select the same IP address that is already being used by subdomain.hosttwo.com, enter 80 as the TCP port, and then enter subdomain.hosttwo.com as the Host Header value. Click OK until you are back to the main IIS Manager window, and you should be good to go. Open a browser, and browse to http://subdomain.hostone.com, and you'll see the site at http://subdomain.hosttwo.com appear, even though your URL shows http://subdomain.hostone.com

Hope that helps...

I find solution that instead of using ListBox I used ListView.It allows to change list items BackColor.

private void listView1_Refresh()
{
    for (int i = 0; i < listView1.Items.Count; i++)
    {
        listView1.Items[i].BackColor = Color.Red;
        for (int j = 0; j < existingStudents.Count; j++)
        {
            if (listView1.Items[i].ToString().Contains(existingStudents[j]))
            {
                listView1.Items[i].BackColor = Color.Green;
            }
        }
    }
}

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

Simply do the following in the script tags:

<!Doctype html>_x000D_
<html>_x000D_
<head>_x000D_
 <title>Circle Canvas</title>_x000D_
</head>_x000D_
<body>_x000D_
 <canvas id="myCanvas" width="300" height="150" style="border:1px solid _x000D_
#d3d3d3;">_x000D_
 <body>_x000D_
  <script>_x000D_
   var c = document.getElementById("myCanvas");_x000D_
   var ctx = c.getContext("2d");_x000D_
   ctx.beginPath();_x000D_
   ctx.arc(100, 75, 50, 0, 2 * Math.PI);_x000D_
   ctx.stroke();_x000D_
  </script>_x000D_
    </body>_x000D_
</body>_x000D_
</html>

And there you go you got your circle.

The best colors I've found --which aside from being so beautiful, are very easy to look at too and do not boil my eyes-- are the ones I've found listed in this GitHub repository: VSCode Snazzy

Very Easy Installation:

Copy the contents of snazzy.json into your VS Code "settings.json" file.

(In case you don't know how to open the "settings.json" file, first hit Ctrl+Shift+P and then write Preferences: open settings(JSON) and hit enter).

Notice: For those who have tried ColorTool and it works outside VSCode but not inside VSCode, you've made no mistakes in implementing it, that's just a decision of VSCode developers for the VSCode's terminal to be colored independently.

Setting the table's separatorStyle to UITableViewCellSeparatorStyleNone (in code or in IB) should do the trick.

    jQuery(function ($) {
        $('li#linkss').find('a').on('click', function (e) {
            var
                link_href = $(this).attr('href')
                , $linkElem = $(link_href)
                , $linkElem_scroll = $linkElem.get(0) && $linkElem.position().top - 115;
            $('html, body')
                .animate({
                    scrollTop: $linkElem_scroll
                }, 'slow');
            e.preventDefault();
        });
    });

A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.

For instance, place your property file in a new folder src/main/config, and add the following to your pom:

 <build>
    <resources>
        <resource>
            <directory>src/main/config</directory>
        </resource>
    </resources>
 </build>

From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <excludes>
                    <exclude>my-config.properties</exclude>
                </excludes>
            </configuration>
        </plugin>
    </plugins>

so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).

Try this one:-

              <MyTextField
                id="originalFileName"
                type="file"
                inputProps={{ accept: '.xlsx, .xls, .pdf' }}
                required
                label="Document"
                name="originalFileName"
                onChange={e => this.handleFileRead(e)}
                size="small"
                variant="standard"
              />

FOR SWIFT 3.0

let str = "iOS Developer Tips encoded in Base64"
print("Original: \(str)")

let utf8str = str.data(using: String.Encoding.utf8)

if let base64Encoded = utf8str?.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
{

  print("Encoded:  \(base64Encoded)")

  if let base64Decoded = NSData(base64Encoded: base64Encoded, options:   NSData.Base64DecodingOptions(rawValue: 0))
    .map({ NSString(data: $0 as Data, encoding: String.Encoding.utf8.rawValue) })
  {
    // Convert back to a string
    print("Decoded:  \(base64Decoded)!")
  }
}

If it doesn't have to be an array, you can create a "multidimensional" JS object...

<script type="text/javascript">
var myObj = { 
    fred: { apples: 2, oranges: 4, bananas: 7, melons: 0 }, 
    mary: { apples: 0, oranges: 10, bananas: 0, melons: 0 }, 
    sarah: { apples: 0, oranges: 0, bananas: 0, melons: 5 } 
}

document.write(myObj['fred']['apples']);
</script>

Assuming $WORKING_DIR is set to the directory... this one-liner should do it:

if [ -d "$WORKING_DIR" ]; then rm -Rf $WORKING_DIR; fi

(otherwise just replace with your directory)

If you want to force-run a single specific directory or daemon's log files, you can usually find the configuration in /etc/logrotate.d, and they will work standalone.

Keep in mind that global configuration specified in /etc/logrotate.conf will not apply, so if you do this you should ensure you specify all the options you want in the /etc/logrotate.d/[servicename] config file specifically.

You can try it out with -d to see what would happen:

logrotate -df /etc/logrotate.d/nginx

Then you can run (using nginx as an example):

logrotate -f /etc/logrotate.d/nginx

And the nginx logs alone will be rotated.

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

The image is taken from this page, which also talks some more about this subject.

document.onreadystatechange = function(){
     if(document.readyState === 'complete'){
         /*code here*/
     }
}

As we know the height of a heap is log(n), where n is the total number of elements.Lets represent it as h
   When we perform heapify operation, then the elements at last level(h) won't move even a single step.
   The number of elements at second last level(h-1) is 2^h-1 and they can move at max 1 level(during heapify).
   Similarly, for the i^th, level we have 2ⁱ elements which can move h-i positions.

Therefore total number of moves=S= 2^h*0+2^h-1*1+2^h-2*2+...2⁰*h

                                               S=2^h {1/2 + 2/2² + 3/2³+ ... h/2^h} -------------------------------------------------1
this is AGP series, to solve this divide both sides by 2
                                               S/2=2^h {1/2² + 2/2³+ ... h/2^h+1} -------------------------------------------------2
subtracting equation 2 from 1 gives
                                               S/2=2^h {1/2+1/2² + 1/2³+ ...+1/2^h+ h/2^h+1}
                                               S=2^h+1 {1/2+1/2² + 1/2³+ ...+1/2^h+ h/2^h+1}
now 1/2+1/2² + 1/2³+ ...+1/2^h is decreasing GP whose sum is less than 1 (when h tends to infinity, the sum tends to 1). In further analysis, let's take an upper bound on the sum which is 1.
This gives S=2^h+1{1+h/2^h+1}
                    =2^h+1+h
                    ~2^h+h
as h=log(n), 2^h=n

Therefore S=n+log(n)
T(C)=O(n)

What if you do this (as was suggested earlier):

new_time = dfs['XYF']['TimeUS'].astype(float)
new_time_F = new_time / 1000000

Finally it worked for me.

<select ng-init="mybasketModel = basket[0]" ng-model="mybasketModel">
        <option ng-repeat="item in basket" ng-selected="$first">{{item}}</option>
</select>

I am using texmaker as the editor. you have to compile it in terminal as following:

1. pdflatex filename (with or without extensions)
2. bibtex filename (without extensions)
3. pdflatex filename (with or without extensions)
4. pdflatex filename (with or without extensions)

but sometimes, when you use \citep{}, the names of the references don't show up. In this case, I had to open the references.bib file , so that texmaker could capture the references from the references.bib file. After every edition of the bib file, I had to close and reopen it!! So that texmaker could capture the content of new .bbl file each time. But remember, you have to also run your code in texmaker too.

I would assume at the end of the day you want to consume the data in the ArrayNode by iterating it. For that:

Iterator<JsonNode> iterator = datasets.withArray("datasets").elements();
while (iterator.hasNext()) 
        System.out.print(iterator.next().toString() + " "); 

or if you're into streams and lambda functions:

import com.google.common.collect.Streams;
Streams.stream(datasets.withArray("datasets").elements())
    .forEach( item -> System.out.print(item.toString()) )

What I have just found is that you need to update your ADT plugin in your Eclipse (whether stand alone or ADT Bundle) before updating your build tool.

If your Eclipse installation points to the most recent Build Tool and your Eclipse is having ADT 22.x, it will show those errors.

What worked for me: (on Ubuntu 14.04 64-bit)

• Installed an older version of Eclipse and ADT (from the Bundle)
• This copy of Eclipse was pointing to an older SDK verion with old build tools (before 20)
• Updated the ADT to v23 (via archive, in my case)
• Pointed Eclipse to the latest version of build tools.

You may not have an older copy of Eclipse and Build tools, in that case you can uninstall latest build tool from SDK Manager and install the older copy.
Once everything starts working fine, do the above steps.

I am trying to upload older copies of such bundles somewhere on the Internet, will update the links here, once I am done uploading.

You could use :focus which will remain the style as long as the user doesn't click elsewhere.

button:active {
    border: 2px solid green;
}

button:focus {
    border: 2px solid red;
}

The following will produce, in the output directory,

• all the package references
• the output assembly
• the bootstrapping exe

But it does not contain all .NET Core runtime assemblies.

<PropertyGroup>
  <Temp>$(SolutionDir)\packaging\</Temp>
</PropertyGroup>

<ItemGroup>
  <BootStrapFiles Include="$(Temp)hostpolicy.dll;$(Temp)$(ProjectName).exe;$(Temp)hostfxr.dll;"/>
</ItemGroup>

<Target Name="GenerateNetcoreExe"
        AfterTargets="Build"
        Condition="'$(IsNestedBuild)' != 'true'">
  <RemoveDir Directories="$(Temp)" />
  <Exec
    ConsoleToMSBuild="true"
    Command="dotnet build $(ProjectPath) -r win-x64 /p:CopyLocalLockFileAssemblies=false;IsNestedBuild=true --output $(Temp)" >

  </Exec>

</Target>

I wrapped it up in a sample here: https://github.com/SimonCropp/NetCoreConsole

The Python 2 syntax works in Python 3 as well:

>>> class MyClass:
...     def __init__(self):
...         self.title = 'Title'
... 
>>> a = MyClass()
>>> print('The title is %(title)s' % a.__dict__)
The title is Title
>>> 
>>> path = '/path/to/a/file'
>>> print('You put your file here: %(path)s' % locals())
You put your file here: /path/to/a/file

Assuming your ints are 0, 375, 668,5 and 6:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [
                       0,
                       375,
                       668,
                       5,
                       6
                   ]
}

I suggest that you change "Id": "610" to "Id": 610 since it is a integer/long and not a string. You can read more about the JSON format and examples here http://json.org/

Coming from someone who has tried a number of "C# IDEs" on the Mac, your best bet is to install a virtual desktop with Windows and Visual Studio. It really is the best development IDE out there for .NET, nothing even comes close.

On a related note: I hate XCode.

Update: Use Xamarin Studio. It's solid.

Yes there is a way to do it.

First declare a class.

//anyfile.ts
export class Custom
{
  name: string, 
  empoloyeeID: number
}

Then in your component import the class

import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
 name: string;
 empoloyeeID : number;
 empList: Array<Custom> = [];
 constructor() {

 }

 ngOnInit() {
 }
 onEmpCreate(){
   //console.log(this.name,this.empoloyeeID);
   let customObj = new Custom();
   customObj.name = "something";
   customObj.employeeId = 12; 
   this.empList.push(customObj);
   this.name ="";
   this.empoloyeeID = 0; 
 }
}

Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html

Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2

i did find something like this, helps get rid of hardcoded tempdata tags

public class AccountController : Controller
{
    [HttpGet]
    public ActionResult Index(IndexPresentationModel model)
    {
        return View(model);
    }

    [HttpPost]
    public ActionResult Save(SaveUpdateModel model)
    {
        // save the information

        var presentationModel = new IndexPresentationModel();

        presentationModel.Message = model.Message;

        return this.RedirectToAction(c => c.Index(presentationModel));
    }
}

You could use jquery to get hold of the html element that you want to load the value with.

Say for instance if your page looks something like this,

<div id="FirstDiv">
  <div id="SecondDiv">
     ...
  </div>
 </div>

And if your javascript (I hope) looks something as simple as this,

function somefunction(){
  var somevalue = "Data to be inserted";
  $("#SecondDiv").text(somevalue);
}

I hope this is what you were looking for.

You can use:

objects_all=Class.objects.filter(filter_condition="")

This will return a query set even if it gets one object. If you need exactly one object use:

obj=Class.objects.get(conditon="")

You need to iterate the 2d array in order to get the min value of each row, then you have to push any gotten min value to another array and finally you need to get the min value of the array where each min row value was pushed

def get_min_value(self, table):
    min_values = []
    for i in range(0, len(table)):
        min_value = min(table[i])
        min_values.append(min_value)

    return min(min_values)

Use --net="host" in your docker run command, then localhost in your docker container will point to your docker host.

In addition to what has already been said about multiple and virtual inheritance(s), there is a very interesting article on Dr Dobb's Journal: Multiple Inheritance Considered Useful

+ this happens because sql sometimes doesn't recognize dd/mm/yyyy format
+ so we should always check if the input string is a valid date or not and the accordingly convert it to mm/dd/yyyy and so , i have shown below how it can be done, i have created a function to rearrange in mm/dd/yyyy from dd/mm/yyyy

select case when isdate('yourdate')=1 then CAST('yourdate' AS datetime) 
  else (select * from dbo.fn_convertdate(yourdate))

Create function dbo.fn_convertdate( @Stringdate nvarchar(29))
RETURNS @output TABLE(splitdata NVARCHAR(MAX) 
)
Begin
Declare @table table(id int identity(1,1), data varchar(255))
Declare @firstpart nvarchar(255)
Declare @tableout table(id int identity(1,1), data varchar(255))

Declare @Secondpart nvarchar(255)
Declare @Thirdpart nvarchar(255)

declare @date datetime

insert into @table
select * from dbo.fnSplitString(@Stringdate,'/')
select @firstpart=data from @table where id=2
select @Secondpart=data from @table where id=1
select @Thirdpart=data from @table where id=3
set @date=@firstpart+'/'+@Secondpart+'/'+@Thirdpart
insert into @output(splitdata) values(
@date)


return
End

For php7.0-fpm I call:

service php7.0-fpm status

php7.0-fpm start/running, process 25993

Now watch for the good part. The process name is actually php-fpm7.0

echo `/bin/pidof php-fpm7.0`

26334 26297 26286 26285 26282

Here is a good article on the matter - "Use references when you can, and pointers when you have to."

String are immutable in Java. You can't change them.

You need to create a new string with the character replaced.

String myName = "domanokz";
String newName = myName.substring(0,4)+'x'+myName.substring(5);

Or you can use a StringBuilder:

StringBuilder myName = new StringBuilder("domanokz");
myName.setCharAt(4, 'x');

System.out.println(myName);

Try this:

import pandas as pd
DataFrame = pd.read_csv("dataset.tsv", sep="\t")

Do not forget to exclude carriage returns from your data !!!

as in:

SELECT 
  Myotherval
  , CASE WHEN TRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '%[^0-9]%' and RTRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '.' and isnumeric(REPLACE([MyVal], char(13) + char(10), '')) = 1 THEN 'my number: ' +  [MyVal]
             ELSE ISNULL(Cast([MyVal] AS VARCHAR(8000)), '')
        END AS 'MyVal'
FROM MyTable

If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):

#!/bin/bash

TABLES=$(mdb-tables -1 $1)

MUSER="root"
MPASS="yourpassword"
MDB="$2"

MYSQL=$(which mysql)

for t in $TABLES
do
    $MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done

mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB

for t in $TABLES
do
    mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done

To invoke it simply call it like this:

./mdbconvert.sh accessfile.mdb mysqldatabasename

It will import all tables and all data.

I am using following:

    using System.Web.Script.Serialization;       

    ...

    public static T ParseResponse<T>(string data)
    {
        return new JavaScriptSerializer().Deserialize<T>(data);
    }

These numbers come from the IEEE-754 standard, which defines the standard representation of floating point numbers. Wikipedia article at the link explains how to arrive at these ranges knowing the number of bits used for the signs, mantissa, and the exponent.

For Spark 2.0.2 with grouping by multiple columns:

import org.apache.spark.sql.functions.row_number
import org.apache.spark.sql.expressions.Window

val w = Window.partitionBy($"col1", $"col2", $"col3").orderBy($"timestamp".desc)

val refined_df = df.withColumn("rn", row_number.over(w)).where($"rn" === 1).drop("rn")

I know this is old, but i think i have good solution. Comparing to other answers and also comparing to accepted, mine accepts multiple values. Basically filter object with key:value search parameters (also object within object). Also it works with numbers etc, cause when comparing, it converts them to string.

import { Pipe, PipeTransform } from '@angular/core';

If you are facing problem with pip3 install pyqt5 then try pip3 install pyqt5==5.12.0
This solved the problem for me

Code coverage basically tells you how much of your code is covered under tests. For example, if you have 90% code coverage, it means 10% of the code is not covered under tests.

I know you might be thinking that if 90% of the code is covered, it's good enough, but you have to look from a different angle. What is stopping you from getting 100% code coverage?

A good example will be this:

if(customer.IsOldCustomer()) 
{
}
else 
{
}

Now, in the code above, there are two paths/branches. If you are always hitting the "YES" branch, you are not covering the "else" part and it will be shown in the Code Coverage results. This is good because now you know that what is not covered and you can write a test to cover the "else" part. If there was no code coverage, you are just sitting on a time bomb, waiting to explode.

NCover is a good tool to measure code coverage.

I'm unable to reproduce your problem but have you tried converting it to an integer first?

image_name_data['id'] = image_name_data['id'].astype(int).astype('str')

Then, regarding your more general question you could use map (as in this answer). In your case:

image_name_data['id'] = image_name_data['id'].map('{:.0f}'.format)

When you want to display information encoded in UTF-8 you may not face problems. Declare for example an HTML document as UTF-8 and you will have everything displayed in your browser that is contained in the body of the document.

But this is not the case when we have text, CSV and XML files, either on Windows or Linux.

For example, a text file in Windows or Linux, one of the easiest things imaginable, it is not (usually) UTF-8.

Save it as XML and declare it as UTF-8:

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

It will not display (it will not be be read) correctly, even if it's declared as UTF-8.

I had a string of data containing French letters, that needed to be saved as XML for syndication. Without creating a UTF-8 file from the very beginning (changing options in IDE and "Create New File") or adding the BOM at the beginning of the file

$file="\xEF\xBB\xBF".$string;

I was not able to save the French letters in an XML file.

T-SQL doesn't have a FOR loop, it has a WHILE loop

I have a slightly different approach than most. Rather than iterate through the collection of views looking for the one that has isFirstResponder set, I too send a message to nil, but I store the receiver of the message so I can return it and do whatever I wish with it.

import UIKit

private var _foundFirstResponder: UIResponder? = nil

extension UIResponder {

    static var first:UIResponder? {

        // Sending an action to 'nil' implicitly sends it to the first responder
        // where we simply capture it and place it in the _foundFirstResponder variable.
        // As such, the variable will contain the current first responder (if any) immediately after this line executes
        UIApplication.shared.sendAction(#selector(UIResponder.storeFirstResponder(_:)), to: nil, from: nil, for: nil)

        // The following 'defer' statement runs *after* this getter returns,
        // thus releasing any strong reference held by the variable immediately thereafter
        defer {
            _foundFirstResponder = nil
        }

        // Return the found first-responder (if any) back to the caller
        return _foundFirstResponder
    }

    @objc func storeFirstResponder(_ sender: AnyObject) {

        // Capture the recipient of this message (self), which is the first responder
        _foundFirstResponder = self
    }
}

With the above, I can resign the first responder by simply doing this...

UIResponder.first?.resignFirstResponder()

But since my API actually hands back whatever the first responder is, I can do whatever I want with it.

Here's an example that checks if the current first responder is a UITextField with a helpMessage property set, and if so, shows it in a help bubble right next to the control. We call this from a 'Quick Help' button on our screen.

func showQuickHelp(){

    if let textField   = UIResponder?.first as? UITextField,
       let helpMessage = textField.helpMessage {
    
        textField.showHelpBubble(with:helpMessage)
    }
}

The support for the above is defined in an extension on UITextField like so...

extension UITextField {
    var helpMessage:String? { ... }
    func showHelpBubble(with message:String) { ... }
}

Now to support this feature, all we have to do is decide which text fields have help messages and the UI takes care of the rest for us.

i just place one image in " d drive-->Data-->IMG". The image name is x.jpg:

And on c# code type

ImageBrush myBrush = new ImageBrush();

myBrush.ImageSource = new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), "D:\\Data\\IMG\\x.jpg"));

(please put double slash in between path)

this.Background = myBrush;

finally i got the background..

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'url_here');
$result = curl_exec($ch);
curl_close($ch);

$obj = json_decode($result);
echo $obj->access_token;

$("**:**input[type=text], :input[type='textarea']").css({width: '90%'});

I needed to process the entire line as a whole. Here is what I found to work.

for /F "tokens=*" %%A in (myfile.txt) do [process] %%A

The tokens keyword with an asterisk (*) will pull all text for the entire line. If you don't put in the asterisk it will only pull the first word on the line. I assume it has to do with spaces.

For Command on TechNet

If there are spaces in your file path, you need to use usebackq. For example.

for /F "usebackq tokens=*" %%A in ("my file.txt") do [process] %%A

Edit .git/config file under your repo directory

Find url= entry under section [remote "origin"]

Change it from url=https://github.com/rootux/ms-Dropdown.git to https://[email protected]/rootux/ms-Dropdown.git

where USERNAME is your github user name

Try the following

Dictionary<int, DateTime> existingItems = 
    (from ObjType ot in TableObj).ToDictionary(x => x.Key);

Or the fully fledged type inferenced version

var existingItems = TableObj.ToDictionary(x => x.Key);

You can add this method to your Status enum:

 public static String getStringValueFromInt(int i) {
     for (Status status : Status.values()) {
         if (status.getValue() == i) {
             return status.toString();
         }
     }
     // throw an IllegalArgumentException or return null
     throw new IllegalArgumentException("the given number doesn't match any Status.");
 }

public static void main(String[] args) {
    System.out.println(Status.getStringValueFromInt(1)); // OUTPUT: START
}

Environment variables are 'evaluated' (ie. they are attributed) in the following order:

1. System variables
2. Variables defined in autoexec.bat
3. User variables

Every process has an environment block that contains a set of environment variables and their values. There are two types of environment variables: user environment variables (set for each user) and system environment variables (set for everyone). A child process inherits the environment variables of its parent process by default.

Programs started by the command processor inherit the command processor's environment variables.

Environment variables specify search paths for files, directories for temporary files, application-specific options, and other similar information. The system maintains an environment block for each user and one for the computer. The system environment block represents environment variables for all users of the particular computer. A user's environment block represents the environment variables the system maintains for that particular user, including the set of system environment variables.

If u want to Selected text clear then using to this code i will make by my self ;)

If e.KeyCode = Keys.Delete Then
    TextBox1.SelectedText = ""
End If

thats it

If you want to only update on rows that are not currently uppercase (instead of all rows), you'd need to identify the difference using COLLATE like this:

UPDATE MyTable
SET    MyColumn = UPPER(MyColumn)
WHERE  MyColumn != UPPER(MyColumn) COLLATE Latin1_General_CS_AS 

A Bit About Collation

Cases sensitivity is based on your collation settings, and is typically case insensitive by default.

Collation can be set at the Server, Database, Column, or Query Level:

-- Server
SELECT SERVERPROPERTY('COLLATION')
-- Database
SELECT name, collation_name FROM sys.databases
-- Column 
SELECT COLUMN_NAME, COLLATION_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE CHARACTER_SET_NAME IS NOT NULL

Collation Names specify how a string should be encoded and read, for example:

• Latin1_General_CI_AS ? Case Insensitive
• Latin1_General_CS_AS ? Case Sensitive

Use the styles

left: 0px;

or/and

right: 0px;

or/and

top: 0px;

or/and

bottom: 0px;

I think for most cases that will do the job

I was facing the same problem.

[remote rejected] master -> master (pre-receive hook declined) error: failed to push some refs to ""

Cause of Error :
I was in develop branch and trying to push to remote master branch

Solution:
Checkout to develop branch(another branch) and execute :

git push heroku develop 

Tried all of the above (short of reboot/ restart docker).

So here is the error om docker rm:

$ docker rm 08d51aad0e74
Error response from daemon: driver "devicemapper" failed to remove root filesystem for 08d51aad0e74060f54bba36268386fe991eff74570e7ee29b7c4d74047d809aa: remove /var/lib/docker/devicemapper/mnt/670cdbd30a3627ae4801044d32a423284b540c5057002dd010186c69b6cc7eea: device or resource busy

Then I did a the following:

$  grep docker /proc/*/mountinfo | grep 958722d105f8586978361409c9d70aff17c0af3a1970cb3c2fb7908fe5a310ac

This got be the PID of the offending process keeping it busy - 20416 (the item after /proc/

So I did a ps -p and to my surprise find:

[devops@dp01app5030 SeGrid]$ ps -p 20416
  PID TTY          TIME CMD
20416 ?        00:00:19 ntpd

A true WTF moment. So I pair problem solved with Google and found this: Then found this https://github.com/docker/for-linux/issues/124

Turns out I had to restart ntp daemon and that fixed the issue!!!

You can't use UIImagePickerController, but you can use a custom image picker. I think ELCImagePickerController is the best option, but here are some other libraries you could use:

12. Alerts-and-pickers/Telegram Picker

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

In addition to the answer of BalusC, use the following Java RegExp to replace && with and:

Search:  (#\{[^\}]*)(&&)([^\}]*\})
Replace: $1and$3

You have run this regular expression replacement multiple times to find all occurences in case you are using >2 literals in your EL expressions. Mind to replace the leading # by $ if your EL expression syntax differs.

You can also use PHP get_headers() function.

Example:

function check_file_exists_here($url){
   $result=get_headers($url);
   return stripos($result[0],"200 OK")?true:false; //check if $result[0] has 200 OK
}

if(check_file_exists_here("http://www.mywebsite.com/file.pdf"))
   echo "This file exists";
else
   echo "This file does not exist";

In actionPerformed(ActionEvent e) you call encrypt(), which is declared to throw Exception. However, actionPerformed neither catches this Exception (with try/catch around the call to encrypt()) nor declares that it throws Exception itself.

Your encrypt method, however, does not truly throw Exception. It swallows all Exceptions without even as much as logging a complaint. (Bad practice and bad style!)

Also, your encrypt method does the following:

public static byte[] encrypt(String toEncrypt) throws Exception {
  try{
    ....
    return encrypted; // HERE YOU CORRECTLY RETURN A VALUE
  } catch(Exception e) {
  }
  // YOU DO NOT RETURN ANYTHING HERE
}

That is, if you do catch any Exception, you discard it silently and then fall off the bottom of your encrypt method without actually returning anything. This won't compile (as you see), because a method that is declared to return a value must either return a value or throw an Exception for every single possible code path.

Please refer this link :

• Go to https://www.anaconda.com/products/individual and click the “Download” -button
• Download the Python 3.7 64-Bit (x86) Installer
• Run the downloaded bash script (.sh) file to begin the installation. See here for more details.
• -When prompted with the question “Do you wish the installer to prepend the Anaconda<2 or 3> install location to PATH in your /home//.bashrc ?”, answer “Yes”. If you enter “No”, you must manually add the path to Anaconda or conda will not work.

Select Windows or linked base command, In my case I have used Linux :

Create a new Anaconda virtual environment Open a new Terminal window

Type the following command: The above will create a new virtual environment with name tensorflow

conda create -n tensorflow pip python=3.8

 conda activate tensorflow

with this function you can print with any n digits you want

function frmtDigit(num, n) {
    isMinus = num < 0;
    if (isMinus)
        num *= -1;
    digit = '';
    if (typeof n == 'undefined')
        n = 2;//two digits
    for (i = 1; i < n; i++) {
        if (num < (1 + Array(i + 1).join("0")))
            digit += '0';
    }
    digit = (isMinus ? '-' : '') + digit + num;
    return digit;
};

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

I have tried wit the below regex it is working fine.

Email validation : \w+([-+.']\w+)@\w+([-.]\w+).\w+([-.]\w+)*

You can do it just like with a property:

FieldInfo fi = typeof(Foo).GetField("_bar", BindingFlags.NonPublic | BindingFlags.Instance);
if (fi.GetCustomAttributes(typeof(SomeAttribute)) != null)
    ...

One way to get the list of distinct column names from the database is to use distinct() in conjunction with values().

In your case you can do the following to get the names of distinct categories:

q = ProductOrder.objects.values('Category').distinct()
print q.query # See for yourself.

# The query would look something like
# SELECT DISTINCT "app_productorder"."category" FROM "app_productorder"

There are a couple of things to remember here. First, this will return a ValuesQuerySet which behaves differently from a QuerySet. When you access say, the first element of q (above) you'll get a dictionary, NOT an instance of ProductOrder.

Second, it would be a good idea to read the warning note in the docs about using distinct(). The above example will work but all combinations of distinct() and values() may not.

PS: it is a good idea to use lower case names for fields in a model. In your case this would mean rewriting your model as shown below:

class ProductOrder(models.Model):
    product  = models.CharField(max_length=20, primary_key=True)
    category = models.CharField(max_length=30)
    rank = models.IntegerField()

I am always used DateDiff(day,date1,date2) to compare two date.

Checkout following example. Just copy that and run in Ms sql server. Also, try with change date by 31 dec to 30 dec and check result

BEGIN

declare @firstDate datetime
declare @secondDate datetime


declare @chkDay int

set @firstDate ='2010-12-31 15:13:48.593'
set @secondDate ='2010-12-31 00:00:00.000'

set @chkDay=Datediff(day,@firstDate ,@secondDate )

if @chkDay=0
    Begin
        Print 'Date is Same'
    end
else
    Begin
        Print 'Date is not Same'
    end
End

If I understand your question correctly, you can always just wrap the get function like so:

var $someJqueryEl = $($('.myJqueryEls').get(3));

In my case I reached the solution in two steps:

1. Keep your project name, package name, folder names short, because if the directory name exceeds 255 characters it gives the mergeResource error.
2. Keep your drawables in the drawable folders. Any drawable file such as .jpg and .png outside the drawable folders throws the mergeResource folder error.

First, you need to check where and why your app has been crashed (Unfortunately, MyApp has stopped.). With the help of LOG, you can figure it out what went wrong.

After that, you find which point your app has stopped fix that from your point.

Experienced this on ubuntu 16.04 running PHP 7.1.14. To resolve,first put this in a script and execute. It will return true if curl is installed and enabled,otherwise, it will return false.

<?php
    var_dump(extension_loaded('curl'));
?>

If it returns false, run

sudo apt-get install php7.1-curl

And finally,

sudo service apache2 restart

After the restart, the script will return true and hopefully, your error should be resolved.

No it is not possible, hence your runtime error.

But you can assign an instance of a derived class to a variable of base class type.

HashMap operation is dependent factor of hashCode implementation. For the ideal scenario lets say the good hash implementation which provide unique hash code for every object (No hash collision) then the best, worst and average case scenario would be O(1). Let's consider a scenario where a bad implementation of hashCode always returns 1 or such hash which has hash collision. In this case the time complexity would be O(n).

Now coming to the second part of the question about memory, then yes memory constraint would be taken care by JVM.

I found very good explanation about .la files here http://openbooks.sourceforge.net/books/wga/dealing-with-libraries.html

Summary (The way I understood): Because libtool deals with static and dynamic libraries internally (through --diable-shared or --disable-static) it creates a wrapper on the library files it builds. They are treated as binary library files with in libtool supported environment.

Select the lines on windows jupyter notebook and then hit Ctrl+#.

I tried some of the supplied answers but none of them seemed to work. Then I tried this:

new webpack.ProvidePlugin({
    'window.jQuery'    : 'jquery',
    'window.$'         : 'jquery',
    'jQuery'           : 'jquery',
    '$'                : 'jquery'
});

Seems to work no matter which version I'm using

As of PHP 5.3 there are two ways to define constants: Either using the const keyword or using the define() function:

const FOO = 'BAR';
define('FOO', 'BAR');

The fundamental difference between those two ways is that const defines constants at compile time, whereas define defines them at run time. This causes most of const's disadvantages. Some disadvantages of const are:

• const cannot be used to conditionally define constants. To define a global constant, it has to be used in the outermost scope:

  if (...) {
      const FOO = 'BAR';    // Invalid
  }
  // but
  if (...) {
      define('FOO', 'BAR'); // Valid
  }
  

  Why would you want to do that anyway? One common application is to check whether the constant is already defined:

  if (!defined('FOO')) {
      define('FOO', 'BAR');
  }
  

• const accepts a static scalar (number, string or other constant like true, false, null, __FILE__), whereas define() takes any expression. Since PHP 5.6 constant expressions are allowed in const as well:

  const BIT_5 = 1 << 5;    // Valid since PHP 5.6 and invalid previously
  define('BIT_5', 1 << 5); // Always valid
  

• const takes a plain constant name, whereas define() accepts any expression as name. This allows to do things like this:

  for ($i = 0; $i < 32; ++$i) {
      define('BIT_' . $i, 1 << $i);
  }
  

• consts are always case sensitive, whereas define() allows you to define case insensitive constants by passing true as the third argument (Note: defining case-insensitive constants is deprecated as of PHP 7.3.0.):

  define('FOO', 'BAR', true);
  echo FOO; // BAR
  echo foo; // BAR
  

So, that was the bad side of things. Now let's look at the reason why I personally always use const unless one of the above situations occurs:

• const simply reads nicer. It's a language construct instead of a function and also is consistent with how you define constants in classes.
• const, being a language construct, can be statically analysed by automated tooling.

• const defines a constant in the current namespace, while define() has to be passed the full namespace name:

  namespace A\B\C;
  // To define the constant A\B\C\FOO:
  const FOO = 'BAR';
  define('A\B\C\FOO', 'BAR');
  

• Since PHP 5.6 const constants can also be arrays, while define() does not support arrays yet. However, arrays will be supported for both cases in PHP 7.

  const FOO = [1, 2, 3];    // Valid in PHP 5.6
  define('FOO', [1, 2, 3]); // Invalid in PHP 5.6 and valid in PHP 7.0
  

Finally, note that const can also be used within a class or interface to define a class constant or interface constant. define cannot be used for this purpose:

class Foo {
    const BAR = 2; // Valid
}
// But
class Baz {
    define('QUX', 2); // Invalid
}

Summary

Unless you need any type of conditional or expressional definition, use consts instead of define()s - simply for the sake of readability!

A somewhat different approach using ggplot2:

dat <- read.table(text = "A   B   C   D   E   F    G
1 480 780 431 295 670 360  190
2 720 350 377 255 340 615  345
3 460 480 179 560  60 735 1260
4 220 240 876 789 820 100   75", header = TRUE)

library(reshape2)

dat$row <- seq_len(nrow(dat))
dat2 <- melt(dat, id.vars = "row")

library(ggplot2)

ggplot(dat2, aes(x = variable, y = value, fill = row)) + 
  geom_bar(stat = "identity") +
  xlab("\nType") +
  ylab("Time\n") +
  guides(fill = FALSE) +
  theme_bw()

this gives:

When you want to include a legend, delete the guides(fill = FALSE) line.

As an alternative to curl, you can use HTTPie, it'a CLI, cURL-like tool for humans.

1. Installation instructions: https://github.com/jakubroztocil/httpie#installation

2. Then, run:

   http -f POST http://localhost:4040/api/users username=johnsnow photo@images/avatar.jpg
   
   HTTP/1.1 200 OK
   Access-Control-Expose-Headers: X-Frontend
   Cache-control: no-store
   Connection: keep-alive

   Pragma: no-cache
   Server: Apache
   Vary: Accept-Encoding
   X-Frontend: front623311
   
   ...
   

Use the ternary operator

direction == 1 ? dosomething () : dosomethingelse ();

You might miss @author and inside of @param you need to explain what's that parameter for, how to use it, etc.

Using @Saikh's answer above, the 2nd option, you can add a space between the time itself and the AM or PM.

REVERSE(LEFT(REVERSE(CONVERT(VARCHAR(20),CONVERT(TIME,myDateTime),100)),2) + ' ' + SUBSTRING(REVERSE(CONVERT(VARCHAR(20),CONVERT(TIME,myDateTime),100)),3,20)) AS [Time],

Messy I know, but it's the solution I chose. Strange that the CONVERT() doesn't add that space automatically. SQL Server 2008 R2

You can use Regular Expressions

if(System.Text.RegularExpressions.IsMatch("a|b|c"))

   UPDATE t1 
    SET 
    t1.a = t2.a,
    t1.b = t2.b,
    .
    .
    .


    FROM 
    table1 t1 
    INNER JOIN table2 t2 ON  t1.id=t2.id

You can try this

When it comes to Google Analytics I found raik's answer at Secure Google tracking cookies very useful. It set secure and samesite to a value.

ga('create', 'UA-XXXXX-Y', {
    cookieFlags: 'max-age=7200;secure;samesite=none'
});

Based on the previous reply, mainly @fcalderan, this marquee scrolls when hovered, with the advantage that the animation scrolls completely even if the text is shorter than the space within it scrolls, also any text length takes the same amount of time (this may be a pros or a cons) when not hovered the text return in the initial position.

No hardcoded value other than the scroll time, best suited for small scroll spaces

While the answers above are valid, if you are iterating over a dict {key:value} it this is the approach I like to use:

for key, value in Dictionary.items():
    print(key, value)

Therefore, if I wanted to do something like stringify all keys and values in my dictionary, I would do this:

stringified_dictionary = {}
for key, value in Dictionary.items():
    stringified_dictionary.update({str(key): str(value)})
return stringified_dictionary

This avoids any mutation issues when applying this type of iteration, which can cause erratic behavior (sometimes) in my experience.

To show NumberPicker in AlertDialog use this code :

final AlertDialog.Builder d = new AlertDialog.Builder(context);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.number_picker_dialog, null);
d.setTitle("Title");
d.setMessage("Message");
d.setView(dialogView);
final NumberPicker numberPicker = (NumberPicker) dialogView.findViewById(R.id.dialog_number_picker);
numberPicker.setMaxValue(50);
numberPicker.setMinValue(1);
numberPicker.setWrapSelectorWheel(false);
numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
    @Override
    public void onValueChange(NumberPicker numberPicker, int i, int i1) {
        Log.d(TAG, "onValueChange: ");
    }
});
d.setPositiveButton("Done", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
        Log.d(TAG, "onClick: " + numberPicker.getValue());
    }
});
d.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
    }
});
AlertDialog alertDialog = d.create();
alertDialog.show();

In my case, i tried all solutions but nothing worked.

My SO is windows 7 x64, with all the Redistributable Packages (x86,x64 / 2010,2013,2015)

The problem was that i tried to install the x64 workbench, but for some reason did not work (even my SO is x64).

so, the solution was download the x86 installer from : https://downloads.mysql.com/archives/workbench/

This error would occur if any of the following variables were actually strings or null instead of arrays, in which case accessing them with an array syntax $var[$i] would be like trying to access a specific character in a string:

$catagory
$task
$fullText
$dueDate
$empId

In short, everything in your insert query.

Perhaps the $catagory variable is misspelled?

You cannot really change the whole URL in the location bar without redirecting (think of the security issues!).

However you can change the hash part (whats after the #) and read that: location.hash

ps. prevent the default onclick redirect of a link by something like:

$("#link").bind("click",function(e){
  doRedirectFunction();
  e.preventDefault();
})

I had a similar issue where visual studio keeps loading symbol and got stuck.

It turns out I added some "Command line arguments" in the Debug options, and one of the parameters is invalid(I am supposed to pass in some values).

After I remove the extra parameter, it starts working again.

If you have the Apache common utilities in your project rather use the first one. Because its shorter and does exactly the same as the latter one. There won't be any difference between both methods but how it looks inside the source code.

Also a empty check using

listName.size() != 0

Is discouraged because all collection implementations have the

listName.isEmpty()

function that does exactly the same.

So all in all, if you have the Apache common utils in your classpath anyway, use

if (CollectionUtils.isNotEmpty(listName)) 

in any other case use

if(listName != null && listName.isEmpty())

You will not notice any performance difference. Both lines do exactly the same.

I'm very late to this game, but my problem started when I upgraded php on my server. I was able to just remove the .socket file and restart my services. Then, everything worked. Not sure why it made a difference, since the file is size 0 and the ownership and permissions are the same, but it worked.

This might be what you're looking for:

// ... rest of code

// copy your state.data to a new array and sort it by itemM in ascending order
// and then map 
const myData = [].concat(this.state.data)
    .sort((a, b) => a.itemM > b.itemM ? 1 : -1)
    .map((item, i) => 
        <div key={i}> {item.matchID} {item.timeM}{item.description}</div>
    );

// render your data here...

The method sort will mutate the original array . Hence I create a new array using the concat method. The sorting on the field itemM should work on sortable entities like string and numbers.

Try this :

<style type="text/css">
        .myTableStyle
        {
           position:absolute;
           top:50%;
           left:50%; 

            /*Alternatively you could use: */
           /*
              position: fixed;
               bottom: 50%;
               right: 50%;
           */


        }
    </style>

I guess this is what you are looking for?

Added an example:

The html:

<div class="example-date">
  <span class="day">31</span> 
  <span class="month">July</span> 
  <span class="year">2009</span>
</div>

The css:

.year
{
    display:block;
    -webkit-transform: rotate(-90deg); 
    -moz-transform: rotate(-90deg); 
    filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3); //For IE support
}

Alle examples are from the mentioned site.

David's answer is correct, but if it's still a little abstract, here are two examples:

1. You might want to zero all freed pointers to catch memory problems earlier. C-style you'd do:

   void freeAndZero(void** ptr)
   {
       free(*ptr);
       *ptr = 0;
   }
   
   void* ptr = malloc(...);
   
   ...
   
   freeAndZero(&ptr);
   

   In C++ to do the same, you might do:

   template<class T> void freeAndZero(T* &ptr)
   {
       delete ptr;
       ptr = 0;
   }
   
   int* ptr = new int;
   
   ...
   
   freeAndZero(ptr);
   

2. When dealing with linked-lists - often simply represented as pointers to a next node:

   struct Node
   {
       value_t value;
       Node* next;
   };
   

   In this case, when you insert to the empty list you necessarily must change the incoming pointer because the result is not the NULL pointer anymore. This is a case where you modify an external pointer from a function, so it would have a reference to pointer in its signature:

   void insert(Node* &list)
   {
       ...
       if(!list) list = new Node(...);
       ...
   }
   

There's an example in this question.

     }

    public void MyAction()

        _action = action;
        _canExecute = canExecute;
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

based on Sam Holder's answer, you could make an extension method for that

namespace adonet.extensions
{
  public static class AdonetExt
  {
    public static int GetInt32(this SqlDataReader reader, string columnName)
    {
      return reader.GetInt32(reader.GetOrdinal(columnName));
    }
  }
}

and use it like this

using adonet.extensions;

//...

int farmsize = reader.GetInt32("farmsize");

assuming there is no GetInt32(string) already in SqlDataReader - if there is any, just use some other method name instead

Well, technically any such object will wind up being built over a C-style thread library because C++ only just specified a stock std::thread model in c++0x, which was just nailed down and hasn't yet been implemented. The problem is somewhat systemic, technically the existing c++ memory model isn't strict enough to allow for well defined semantics for all of the 'happens before' cases. Hans Boehm wrote an paper on the topic a while back and was instrumental in hammering out the c++0x standard on the topic.

http://www.hpl.hp.com/techreports/2004/HPL-2004-209.html

That said there are several cross-platform thread C++ libraries that work just fine in practice. Intel thread building blocks contains a tbb::thread object that closely approximates the c++0x standard and Boost has a boost::thread library that does the same.

http://www.threadingbuildingblocks.org/

http://www.boost.org/doc/libs/1_37_0/doc/html/thread.html

Using boost::thread you'd get something like:

#include <boost/thread.hpp>

void task1() { 
    // do stuff
}

void task2() { 
    // do stuff
}

int main (int argc, char ** argv) {
    using namespace boost; 
    thread thread_1 = thread(task1);
    thread thread_2 = thread(task2);

    // do other stuff
    thread_2.join();
    thread_1.join();
    return 0;
}

If the element you're analyzing does not have any margin, border or whatsoever defined you won't be able to return it. At tops you'll be able to get 'auto' which is normally the default.

From your example I can see that you have margT as variable. Not sure if're trying to get margin-top. If that's the case you should be using .css('margin-top').

You're also trying to get the stylization from 'img' which will result (if you have more than one) in an array.

What you should do is use the .each() jquery method.

For example:

jQuery('img').each(function() {
    // get margin top
    var margT = jQuery(this).css('margin-top');

    // Do something with margT
});

Not exactly the answer to the question, but I needed to scroll down as soon as an EditText got the focus. However the accepted answer would make the ET also lose focus right away (to the ScrollView I assume).

My workaround was the following:

emailEt.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if(hasFocus){
            Toast.makeText(getActivity(), "got the focus", Toast.LENGTH_LONG).show();
            scrollView.postDelayed(new Runnable() {
                @Override
                public void run() {
                    scrollView.fullScroll(ScrollView.FOCUS_DOWN);
                }
            }, 200);
        }else {
            Toast.makeText(getActivity(), "lost the focus", Toast.LENGTH_LONG).show();
        }
    }
});

length and dbms_lob.getlength return the number of characters when applied to a CLOB (Character LOB). When applied to a BLOB (Binary LOB), dbms_lob.getlength will return the number of bytes, which may differ from the number of characters in a multi-byte character set.

As the documentation doesn't specify what happens when you apply length on a BLOB, I would advise against using it in that case. If you want the number of bytes in a BLOB, use dbms_lob.getlength.

#Implement a generic return stack for functions:

STACK=()
push() {
  STACK+=( "${1}" )
}
pop() {
  export $1="${STACK[${#STACK[@]}-1]}"
  unset 'STACK[${#STACK[@]}-1]';
}

#Usage:

my_func() {
  push "Hello world!"
  push "Hello world2!"
}
my_func ; pop MESSAGE2 ; pop MESSAGE1
echo ${MESSAGE1} ${MESSAGE2}

You want to have a look at FileField and FieldFile in the Django docs, and especially FieldFile.save().

Basically, a field declared as a FileField, when accessed, gives you an instance of class FieldFile, which gives you several methods to interact with the underlying file. So, what you need to do is:

self.license_file.save(new_name, new_contents)

where new_name is the filename you wish assigned and new_contents is the content of the file. Note that new_contents must be an instance of either django.core.files.File or django.core.files.base.ContentFile (see given links to manual for the details).

The two choices boil down to:

from django.core.files.base import ContentFile, File

# Using File
with open('/path/to/file') as f:
    self.license_file.save(new_name, File(f))

# Using ContentFile
self.license_file.save(new_name, ContentFile('A string with the file content'))

This might serve as a good starting point for moving/rotating/zooming a camera with mouse/trackpad (in typescript):

class CameraControl {
    zoomMode: boolean = false
    press: boolean = false
    sensitivity: number = 0.02

    constructor(renderer: Three.Renderer, public camera: Three.PerspectiveCamera, updateCallback:() => void){
        renderer.domElement.addEventListener('mousemove', event => {
            if(!this.press){ return }

            if(event.button == 0){
                camera.position.y -= event.movementY * this.sensitivity
                camera.position.x -= event.movementX * this.sensitivity        
            } else if(event.button == 2){
                camera.quaternion.y -= event.movementX * this.sensitivity/10
                camera.quaternion.x -= event.movementY * this.sensitivity/10
            }

            updateCallback()
        })    

        renderer.domElement.addEventListener('mousedown', () => { this.press = true })
        renderer.domElement.addEventListener('mouseup', () => { this.press = false })
        renderer.domElement.addEventListener('mouseleave', () => { this.press = false })

        document.addEventListener('keydown', event => {
            if(event.key == 'Shift'){
                this.zoomMode = true
            }
        })

        document.addEventListener('keyup', event => {
            if(event.key == 'Shift'){
                this.zoomMode = false
            }
        })

        renderer.domElement.addEventListener('mousewheel', event => {
            if(this.zoomMode){ 
                camera.fov += event.wheelDelta * this.sensitivity
                camera.updateProjectionMatrix()
            } else {
                camera.position.z += event.wheelDelta * this.sensitivity
            }

            updateCallback()
        })
    }
}

drop it in like:

this.cameraControl = new CameraControl(renderer, camera, () => {
    // you might want to rerender on camera update if you are not rerendering all the time
    window.requestAnimationFrame(() => renderer.render(scene, camera))
})

Controls:

• move while [holding mouse left / single finger on trackpad] to move camera in x/y plane
• move [mouse wheel / two fingers on trackpad] to move up/down in z-direction
• hold shift + [mouse wheel / two fingers on trackpad] to zoom in/out via increasing/decreasing field-of-view
• move while holding [mouse right / two fingers on trackpad] to rotate the camera (quaternion)

Additionally:

If you want to kinda zoom by changing the 'distance' (along yz) instead of changing field-of-view you can bump up/down camera's position y and z while keeping the ratio of position's y and z unchanged like:

// in mousewheel event listener in zoom mode
const ratio = camera.position.y / camera.position.z
camera.position.y += (event.wheelDelta * this.sensitivity * ratio)
camera.position.z += (event.wheelDelta * this.sensitivity)

This should be an answer

str2.equals( str )

If you want to ignore case

str2.equalsIgnoreCase( str )

scp is best for one file.
OR a combination of tar & compression for smaller data sets like source code trees with small resources (ie: images, sqlite etc).

• media folders (40 GB)
• database backups (28 GB)
• mp3 libraries (100 GB)

It becomes impractical to build a zip/tar.gz file to transfer with scp at this point do to the physical limits of the hosted server.

As an exercise, you can do some gymnastics like piping tar into ssh and redirecting the results into a remote file. (saving the need to build a swap or temporary clone aka zip or tar.gz)

However,

rsync simplify's this process and allows you to transfer data without consuming any additional disc space.

Also,

Continuous (cron?) updates use minimal changes vs full cloned copies speed up large data migrations over time.

tl;dr
scp == small scale (with room to build compressed files on the same drive)
rsync == large scale (with the necessity to backup large data and no room left)

There is another way to draw a circle - draw it in fragment shader. Create a quad:

float right = 0.5;
float bottom = -0.5;
float left = -0.5;
float top = 0.5;
float quad[20] = {
    //x, y, z, lx, ly
    right, bottom, 0, 1.0, -1.0,
    right, top, 0, 1.0, 1.0,
    left, top, 0, -1.0, 1.0,
    left, bottom, 0, -1.0, -1.0,
};

Bind VBO:

unsigned int glBuffer;
glGenBuffers(1, &glBuffer);
glBindBuffer(GL_ARRAY_BUFFER, glBuffer);
glBufferData(GL_ARRAY_BUFFER, sizeof(float)*20, quad, GL_STATIC_DRAW);

and draw:

#define BUFFER_OFFSET(i) ((char *)NULL + (i))
glEnableVertexAttribArray(ATTRIB_VERTEX);
glEnableVertexAttribArray(ATTRIB_VALUE);
glVertexAttribPointer(ATTRIB_VERTEX , 3, GL_FLOAT, GL_FALSE, 20, 0);
glVertexAttribPointer(ATTRIB_VALUE , 2, GL_FLOAT, GL_FALSE, 20, BUFFER_OFFSET(12));
glDrawArrays(GL_TRIANGLE_FAN, 0, 4);

Vertex shader

attribute vec2 value;
uniform mat4 viewMatrix;
uniform mat4 projectionMatrix;
varying vec2 val;
void main() {
    val = value;
    gl_Position = projectionMatrix*viewMatrix*vertex;
}

Fragment shader

varying vec2 val;
void main() {
    float R = 1.0;
    float R2 = 0.5;
    float dist = sqrt(dot(val,val));
    if (dist >= R || dist <= R2) {
        discard;
    }
    float sm = smoothstep(R,R-0.01,dist);
    float sm2 = smoothstep(R2,R2+0.01,dist);
    float alpha = sm*sm2;
    gl_FragColor = vec4(0.0, 0.0, 1.0, alpha);
}

Don't forget to enable alpha blending:

glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);

Create a Child Component that use ngOnChanges.

ChildComponent.ts::

import { Component, OnChanges, Input } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'child',
  templateUrl: 'child.component.html',
})

export class ChildComponent implements OnChanges {
  @Input() child_id;

  constructor(private route: ActivatedRoute) { }

  ngOnChanges() {
    // create header using child_id
    console.log(this.child_id);
  }
}

now use it in MasterComponent's template and pass data to ChildComponent like:

<child [child_id]="child_id"></child>

You can use:

getResources().getColor(R.color.idname);

Check here on how to define custom colors:

http://sree.cc/google/android/defining-custom-colors-using-xml-in-android

EDIT(1): Since getColor(int id) is deprecated now, this must be used :

ContextCompat.getColor(context, R.color.your_color);

(added in support library 23)

EDIT(2):

Below code can be used for both pre and post Marshmallow (API 23)

ResourcesCompat.getColor(getResources(), R.color.your_color, null); //without theme

ResourcesCompat.getColor(getResources(), R.color.your_color, your_theme); //with theme

I assume you want to link to a library called foo, its filename is usually something link foo.dll or libfoo.so.

1. Find the library
You have to find the library. This is a good idea, even if you know the path to your library. CMake will error out if the library vanished or got a new name. This helps to spot error early and to make it clear to the user (may yourself) what causes a problem.
To find a library foo and store the path in FOO_LIB use

    find_library(FOO_LIB foo)

CMake will figure out itself how the actual file name is. It checks the usual places like /usr/lib, /usr/lib64 and the paths in PATH.

You already know the location of your library. Add it to the CMAKE_PREFIX_PATH when you call CMake, then CMake will look for your library in the passed paths, too.

Sometimes you need to add hints or path suffixes, see the documentation for details: https://cmake.org/cmake/help/latest/command/find_library.html

2. Link the library From 1. you have the full library name in FOO_LIB. You use this to link the library to your target GLBall as in

  target_link_libraries(GLBall PRIVATE "${FOO_LIB}")

You should add PRIVATE, PUBLIC, or INTERFACE after the target, cf. the documentation: https://cmake.org/cmake/help/latest/command/target_link_libraries.html

If you don't add one of these visibility specifiers, it will either behave like PRIVATE or PUBLIC, depending on the CMake version and the policies set.

3. Add includes (This step might be not mandatory.)
If you also want to include header files, use find_path similar to find_library and search for a header file. Then add the include directory with target_include_directories similar to target_link_libraries.

Documentation: https://cmake.org/cmake/help/latest/command/find_path.html and https://cmake.org/cmake/help/latest/command/target_include_directories.html

If available for the external software, you can replace find_library and find_path by find_package.

Personally I dislike hanging open blocks, so I'd format it as:

logger.info(
    'Skipping {0} because its thumbnail was already in our system as {1}.'
    .format(line[indexes['url']], video.title)
)

In general I wouldn't bother struggle too hard to make code fit exactly within a 80-column line. It's worth keeping line length down to reasonable levels, but the hard 80 limit is a thing of the past.

preg_match('/'.preg_quote('^\'£$%^&*()}{@#~?><,@|-=-_+-¬', '/').'/', $string);
