Programs & Examples On #Xsd validation

I have noticed that XMLSpy(at least 2011 version)needs a targetNameSpace defined if elementFormDefault="qualified" is used. Otherwise won't validate. And also won't generate xmls with namespace prefixes

For me this was caused by a VS extension for measuring code coverage. It could not reference a particular assembly, and therefore would not run any of the tests. Tests would run fine from the command line using:

dotnet test

To solve this issue, you can opt to have ALL dependencies copied to your Test project debug folder. This ensures that any assemblies can be resolved, as "unused" assemblies are not removed. You can add the following to your Test projects .csprog file:

<PropertyGroup>
    <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
</PropertyGroup>

The accepted answer of how to create an Index inline a Table creation script did not work for me. This did:

CREATE TABLE [dbo].[TableToBeCreated]
(
    [Id] BIGINT IDENTITY(1, 1) NOT NULL PRIMARY KEY
    ,[ForeignKeyId] BIGINT NOT NULL
    ,CONSTRAINT [FK_TableToBeCreated_ForeignKeyId_OtherTable_Id] FOREIGN KEY ([ForeignKeyId]) REFERENCES [dbo].[OtherTable]([Id])
    ,INDEX [IX_TableToBeCreated_ForeignKeyId] NONCLUSTERED ([ForeignKeyId])
)

Remember, Foreign Keys do not create Indexes, so it is good practice to index them as you will more than likely be joining on them.

use the following way to convert the array to an object easily.

var obj = {};
array.forEach(function(e){
   obj[e[0]] = e[1]
})

This will use the first element as the key and the second element as the value for each element.

Here is how I got it going specifically for the admob sdk jar file:

1. Drag your jar file into the libs folder.
2. Right click on the jar file and select Add Library now the jar file is a library lets add it to the compile path
3. Open the build.gradle file (note there are two build.gradle files at least, don't use the root one use the one in your project scope).

4. Find the dependencies section (for me i was trying to the admob -GoogleAdMobAdsSdk jar file) e.g.

   dependencies {
      compile files('libs/android-support-v4.jar','libs/GoogleAdMobAdsSdk-6.3.1.jar')
   }
   

5. Last go into settings.gradle and ensure it looks something like this:

   include ':yourproject', ':yourproject:libs:GoogleAdMobAdsSdk-6.3.1'
   

6. Finally, Go to Build -> Rebuild Project

max-age=0

This is equivalent to clicking Refresh, which means, give me the latest copy unless I already have the latest copy.

no-cache

This is holding Shift while clicking Refresh, which means, just redo everything no matter what.

If you want to use fetch instead:

var myImage = document.querySelector('img');

fetch('flowers.jpg').then(function(response) {
  return response.blob();
}).then(function(myBlob) {
  var objectURL = URL.createObjectURL(myBlob);
  myImage.src = objectURL;
});

I needed to rotate a 3D model around one of the three axes {x, y, z} in which that model was embedded and this was the top result for a search of how to do this in numpy. I used the following simple function:

def rotate(X, theta, axis='x'):
  '''Rotate multidimensional array `X` `theta` degrees around axis `axis`'''
  c, s = np.cos(theta), np.sin(theta)
  if axis == 'x': return np.dot(X, np.array([
    [1.,  0,  0],
    [0 ,  c, -s],
    [0 ,  s,  c]
  ]))
  elif axis == 'y': return np.dot(X, np.array([
    [c,  0,  -s],
    [0,  1,   0],
    [s,  0,   c]
  ]))
  elif axis == 'z': return np.dot(X, np.array([
    [c, -s,  0 ],
    [s,  c,  0 ],
    [0,  0,  1.],
  ]))

If the label immediately follows a specified input element:

input#example + label { ... }
input:checked + label { ... }

use a negative character class:

[^,;]+

function hexToStr($hex){
    // Remove spaces if the hex string has spaces
    $hex = str_replace(' ', '', $hex);
    return hex2bin($hex);
}
// Test it 
$hex    = "53 44 43 30 30 32 30 30 30 31 37 33";
echo hexToStr($hex); // SDC002000173

/**
 * Test Hex To string with PHP UNIT
 * @param  string $value
 * @return 
 */
public function testHexToString()
{
    $string = 'SDC002000173';
    $hex    = "53 44 43 30 30 32 30 30 30 31 37 33";
    $result = hexToStr($hex);

    $this->assertEquals($result,$string);
}

Look how I format my date $jour in the parameters. It depends if you use a expr()->like or a expr()->lte

$qb
        ->select('e')
        ->from('LdbPlanningBundle:EventEntity', 'e')
        ->where(
            $qb->expr()->andX(
                $qb->expr()->orX(
                    $qb->expr()->like('e.start', ':jour1'),
                    $qb->expr()->like('e.end', ':jour1'),
                    $qb->expr()->andX(
                        $qb->expr()->lte('e.start', ':jour2'),
                        $qb->expr()->gte('e.end', ':jour2')
                    )
                ),
                $qb->expr()->eq('e.user', ':user')
            )
        )
        ->andWhere('e.user = :user ')
        ->setParameter('user', $user)
        ->setParameter('jour1', '%'.$jour->format('Y-m-d').'%')
        ->setParameter('jour2', $jour->format('Y-m-d'))
        ->getQuery()
        ->getArrayResult()
    ;

If you still have the "open perspective" button in the top right, you can switch to a different perspective, go to Windows -> Preferences -> General -> Keys, and apply a key binding for "Reset Perspective". Then, switch back to the afflicted perspective and hit that key binding.

    DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
    System.out.println(LocalDate.parse("08/16/2011", dateFormatter));

Output:

2011-08-16

I am contributing the modern answer. The answer by Bohemian is correct and was a good answer when it was written 6 years ago. Now the notoriously troublesome SimpleDateFormat class is long outdated and we have so much better in java.time, the modern Java date and time API. I warmly recommend you use this instead of the old date-time classes.

What went wrong in your code?

When I parse 08/16/2011 using your snippet, I get Sun Jan 16 00:08:00 CET 2011. Since lowercase mm is for minutes, I get 00:08:00 (8 minutes past midnight), and since uppercase DD is for day of year, I get 16 January.

In java.time too format pattern strings are case sensitive, and we needed to use uppercase MM for month and lowercase dd for day of month.

Question: Can I use java.time with my Java version?

Yes, java.time works nicely on Java 6 and later and on both older and newer Android devices.

• In Java 8 and later and on new Android devices (from API level 26, I’m told) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the new classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

Simple program

import java.io.*;
class Aclass
{
    public int a;
}
public class test
{
    public static void foo_obj(Aclass obj)
    {
        obj.a=5;
    }
    public static void foo_int(int a)
    {
        a=3;
    }
    public static void main(String args[])
    {
        //test passing an object
        Aclass ob = new Aclass();
        ob.a=0;
        foo_obj(ob);
        System.out.println(ob.a);//prints 5

        //test passing an integer
        int i=0;
        foo_int(i);
        System.out.println(i);//prints 0
    }
}

From a C/C++ programmer's point of view, java uses pass by value, so for primitive data types (int, char etc) changes in the function does not reflect in the calling function. But when you pass an object and in the function you change its data members or call member functions which can change the state of the object, the calling function will get the changes.

All browsers since IE9+ have trim() method for strings:

" \n test \n ".trim(); // returns "test" here

For those browsers who does not support trim(), you can use this polyfill from MDN:

if (!String.prototype.trim) {
    (function() {
        // Make sure we trim BOM and NBSP
        var rtrim = /^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g;
        String.prototype.trim = function() {
            return this.replace(rtrim, '');
        };
    })();
}

That said, if using jQuery, $.trim(str) is also available and handles undefined/null.

See this:

String.prototype.trim=function(){return this.replace(/^\s+|\s+$/g, '');};

String.prototype.ltrim=function(){return this.replace(/^\s+/,'');};

String.prototype.rtrim=function(){return this.replace(/\s+$/,'');};

String.prototype.fulltrim=function(){return this.replace(/(?:(?:^|\n)\s+|\s+(?:$|\n))/g,'').replace(/\s+/g,' ');};

Setting tcp-keepalive to 60 (it was set to 0) in server's redis configuration helped me resolve this issue.

Solution 1:

The most reliable and unobtrusive method appears to be this:

Demo: http://jsfiddle.net/SO_AMK/wXaEH/

HTML:

<div class="clearfix">
    <div style="float: left;">Div 1</div>
    <div style="float: left;">Div 2</div>
</div>?

CSS:

.clearfix::after { 
   content: " ";
   display: block; 
   height: 0; 
   clear: both;
}

?With a little CSS targeting, you don't even need to add a class to the parent DIV.

This solution is backward compatible with IE8 so you don't need to worry about older browsers failing.

Solution 2:

An adaptation of solution 1 has been suggested and is as follows:

Demo: http://jsfiddle.net/wXaEH/162/

HTML:

<div class="clearfix">
    <div style="float: left;">Div 1</div>
    <div style="float: left;">Div 2</div>
</div>?

CSS:

.clearfix::after { 
   content: " ";
   display: block; 
   height: 0; 
   clear: both;
   *zoom: expression( this.runtimeStyle['zoom'] = '1', this.innerHTML += '<div class="ie7-clear"></div>' );
}

.ie7-clear {
    display: block;
    clear: both;
}

This solution appears to be backward compatible to IE5.5 but is untested.

Solution 3:

It's also possible to set display: inline-block; and width: 100%; to emulate a normal block element while not collapsing.

Demo: http://jsfiddle.net/SO_AMK/ae5ey/

CSS:

.clearfix {
    display: inline-block;
    width: 100%;
}

This solution should be backward compatible with IE5.5 but has only been tested in IE6.

You can do this way:

if($(selector).filter('.class1, .class2').length){
    // Or logic
}

if($(selector).filter('.class1, .class2').length){
    // And logic
}

I find it easier to implement it in the XML file as it can be harder to trace the line of code in a class with hundreds of lines. For the XML you can use "null":

android:divider="@null"

If you want to get client key from request header, u can try following:

from rest_framework.authentication import BaseAuthentication
from rest_framework import exceptions
from apps.authentication.models import CerebroAuth

class CerebroAuthentication(BaseAuthentication):
def authenticate(self, request):
    client_id = request.META.get('HTTP_AUTHORIZATION')
    if not client_id:
        raise exceptions.AuthenticationFailed('Client key not provided')
    client_id = client_id.split()
    if len(client_id) == 1 or len(client_id) > 2:
        msg = ('Invalid secrer key header. No credentials provided.')
        raise exceptions.AuthenticationFailed(msg)
    try:
        client = CerebroAuth.objects.get(client_id=client_id[1])
    except CerebroAuth.DoesNotExist:
        raise exceptions.AuthenticationFailed('No such client')
    return (client, None)

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

Its little tricky in android studio there is no default folder for all screen size you need to create but with little trick.

• when you paste your image into drawable folder a popup will appear to ask about directory
• Add subfolder name after drawable like drawable-xxhdpi
• I will suggest you to paste image with highest resolution it will auto detect for other size.. thats it next time when you will paste it will ask to you about directory

i cant post image here so if still having any problem. here is tutorial..

Drawable folder in android studio

XmlDocument.Attributes perhaps? (Which has a method GetNamedItem that will presumably do what you want, although I've always just iterated the attribute collection)

MVC Controller:

    [HttpGet]
    public ActionResult DetailList(ImportDetailSearchModel model)
    {
        Data.ImportDataAccess ida = new Data.ImportDataAccess();
        List<Data.ImportDetailData> data = ida.GetImportDetails(model.FileId, model.FailuresOnly);

        return PartialView("ImportSummaryDetailPartial", data);
    }

MVC View:

<table class="sortable">
<thead>
    <tr><th>Unique Id</th><th class="left">Error Type</th><th class="left">Field</th><th class="left">Message</th><th class="left">State</th></tr>
</thead>
<tbody>
    @foreach (Data.ImportDetailData detail in Model)
    {
    <tr><th>@detail.UniqueID</th><th class="left">@detail.ErrorType</th><th class="left">@detail.FieldName</th><th class="left">@detail.Message</th><th class="left">@detail.ItemState</th></tr>
    }
</tbody></table>

How hard is that? No ViewState, No BS Page life-cycle...Just pure efficient code.

a couple ways:

1. Absolute positioning-- you need to have a declared height to make this work:

<div>
   <div class='center'>Hey</div>
</div>

div {height: 100%; width: 100%; position: relative}
div.center {
     width: 100px;
     height: 100px;
     top: 50%;
     margin-top: -50px;
}

*2. Use display: table http://jsfiddle.net/B7CpL/2/ *

<div>
     <img src="/img.png" />
     <div class="text">text centered with image</div>
</div>


div {
     display: table;
     vertical-align: middle
}

div img,
div.text {
     display: table-cell;
     vertical-align: middle
}

The answer here(scrolling in $(document).ready) doesn't work if there is a video in the page. In that case the page is scrolled after this event is fired, overriding our work.

Best answer should be:

$(window).on('beforeunload', function(){
    $(window).scrollTop(0);
});

You can try this to simple date format valdation

 public Date validateDateFormat(String dateToValdate) {

    SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HHmmss");
    //To make strict date format validation
    formatter.setLenient(false);
    Date parsedDate = null;
    try {
        parsedDate = formatter.parse(dateToValdate);
        System.out.println("++validated DATE TIME ++"+formatter.format(parsedDate));

    } catch (ParseException e) {
        //Handle exception
    }
    return parsedDate;
}

x=3#rows
y=3#columns
a=[]#create an empty list first
for i in range(x):
    a.append([0]*y)#And again append empty lists to original list
    for j in range(y):
         a[i][j]=input("Enter the value")

1. Create a file in drawable play_pause.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true"
          android:drawable="@drawable/pause" />

    <item android:state_selected="false"
          android:drawable="@drawable/play" />
    <!-- default -->
</selector>

2. In xml file add this below code

 <ImageView
                android:id="@+id/iv_play"
                android:layout_width="@dimen/_50sdp"
                android:layout_height="@dimen/_50sdp"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:background="@drawable/pause_button"
                android:gravity="center"
                android:scaleType="fitXY" />

3. In java file add this below code

iv_play = (ImageView) findViewById(R.id.iv_play);
iv_play.setSelected(false);

and also add this

iv_play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                iv_play.setSelected(!iv_play.isSelected());
                if (iv_play.isSelected()) {
                    ((GifDrawable) gif_1.getDrawable()).start();
                    ((GifDrawable) gif_2.getDrawable()).start();
                } else {
                    iv_play.setSelected(false);
                    ((GifDrawable) gif_1.getDrawable()).stop();
                    ((GifDrawable) gif_2.getDrawable()).stop();
                }
            }
        });

As another guy described here, all you need to do is add

height: 100vh;

to the style of whatever you need to fill the screen

As was indicated by others, you don't need to use malloc just to do:

const char *foo = "bar";

The reason for that is exactly that *foo is a pointer — when you initialize foo you're not creating a copy of the string, just a pointer to where "bar" lives in the data section of your executable. You can copy that pointer as often as you'd like, but remember, they're always pointing back to the same single instance of that string.

So when should you use malloc? Normally you use strdup() to copy a string, which handles the malloc in the background. e.g.

const char *foo = "bar";
char *bar = strdup(foo); /* now contains a new copy of "bar" */
printf("%s\n", bar);     /* prints "bar" */
free(bar);               /* frees memory created by strdup */

Now, we finally get around to a case where you may want to malloc if you're using sprintf() or, more safely snprintf() which creates / formats a new string.

char *foo = malloc(sizeof(char) * 1024);        /* buffer for 1024 chars */
snprintf(foo, 1024, "%s - %s\n", "foo", "bar"); /* puts "foo - bar\n" in foo */
printf(foo);                                    /* prints "foo - bar" */
free(foo);                                      /* frees mem from malloc */

This is add new string in the file

using (var file = new StreamWriter(filePath + "log.txt", true))
        {
            file.WriteLine(log);
            file.Close();
        }

As it allows to install more than one version of java, I had install many 3 versions unknowingly but it was point to latest version "11.0.2"

I could able to solve this issue with below steps to move to "1.8"

JpaRepository also extends QueryByExampleExecutor. So you don't even need to define custom methods on your interface:

public interface UserRepository extends JpaRepository<User, Long> {
    // no need of custom method
}

And then query like:

User probe = new User();
u.setName = "John";
long count = repo.count(Example.of(probe));

I had a similar problem as you. What I did is that I use something called jQuery. What you then do in the javascript code is this:

$(function(){ //this is regular jQuery code. It waits for the dom to load fully the first time you open the page.

    $("#myIframeId").load(function(){
       callback($("#myIframeId").html());
       $("#myIframeId").remove();

    });

});

It seems as you delete you iFrame before you grab the html from it. Now, I do see a problem with that :p

Hope this helps :).

The return statement only makes sense inside functions:

def foo():
    while True:
        return False

Updating to 2012, when we see that image sizes, and number of images, are growing and growing, in all applications...

We need some distinction between "original image" and "processed image", like thumbnail.

As Jcoby's answer says, there are two options, then, I recommend:

• use blob (Binary Large OBject): for original image store, at your table. See Ivan's answer (no problem with backing up blobs!), PostgreSQL additional supplied modules, How-tos etc.

• use a separate database with DBlink: for original image store, at another (unified/specialized) database. In this case, I prefer bytea, but blob is near the same. Separating database is the best way for a "unified image webservice".

• use bytea (BYTE Array): for caching thumbnail images. Cache the little images to send it fast to the web-browser (to avoiding rendering problems) and reduce server processing. Cache also essential metadata, like width and height. Database caching is the easiest way, but check your needs and server configs (ex. Apache modules): store thumbnails at file system may be better, compare performances. Remember that it is a (unified) web-service, then can be stored at a separate database (with no backups), serving many tables. See also PostgreSQL binary data types manual, tests with bytea column, etc.

NOTE1: today the use of "dual solutions" (database+filesystem) is deprecated (!). There are many advantages to using "only database" instead dual. PostgreSQL have comparable performance and good tools for export/import/input/output.

NOTE2: remember that PostgreSQL have only bytea, not have a default Oracle's BLOB: "The SQL standard defines (...) BLOB. The input format is different from bytea, but the provided functions and operators are mostly the same",Manual.

EDIT 2014: I have not changed the original text above today (my answer was Apr 22 '12, now with 14 votes), I am opening the answer for your changes (see "Wiki mode", you can edit!), for proofreading and for updates.

Although the ffile:////.exe used to work (for example - some versions of early html 4) it appears html 5 disallows this. Tested using the following:

<a href="ffile:///<path name>/<filename>.exe" TestLink /a> 
<a href="ffile://<path name>/<filename>.exe" TestLink /a> 
<a href="ffile:/<path name>/<filename>.exe" TestLink /a> 
<a href="ffile:<path name>/<filename>.exe" TestLink /a> 
<a href="ffile://///<path name>/<filename>.exe" TestLink /a> 
<a href="file://<path name>/<filename>.exe" TestLink /a> 
<a href="file:/<path name>/<filename>.exe" TestLink /a> 
<a href="file:<path name>/<filename>.exe" TestLink /a> 
<a href="ffile://///<path name>/<filename>.exe" TestLink /a>

as well as ... 1/ substituted the "ffile" with just "file" 2/ all the above variations with the http:// prefixed before the ffile or file.

The best I could see was there is a possibility that if one wanted to open (edit) or save the file, it could be accomplished. However, the exec file would not execute otherwise.

You can't do what you're asking natively with an array, but javascript objects are hashes, so you can say...

var hash = {};
hash['k1'] = 'abc';
...

Then you can retrieve using bracket or dot notation:

alert(hash['k1']); // alerts 'abc'
alert(hash.k1); // also alerts 'abc'

For arrays, check the underscore.js library in general and the detect method in particular. Using detect you could do something like...

_.detect(arr, function(x) { return x.name == 'k1' });

Or more generally

MyCollection = function() {
  this.arr = [];
}

MyCollection.prototype.getByName = function(name) {
  return _.detect(this.arr, function(x) { return x.name == name });
}

MyCollection.prototype.push = function(item) {
  this.arr.push(item);
}

etc...

In Python 3.4+:

import html

html.unescape(your_string)

While maintaining the proper .gitignore file is helpful, I found this alternate approach is way cleaner and easier to use.

• Create dummy folder my_project and inside that git clone my_real_project the actual project repo.
• Now while opening the project in IDE (Intellij/Pycharm) open the folder my_project and mark my_project/my_real_project as the VCS root.
• You can see my_project/.idea wouldn't pollute your git repo because it happily lives outside the git repo which is what you want. This way your .gitignore files stays clean as well.

This approach works better due to the below reasons.

1 - .gitignore file stays clean and we don't have to insert lines related to JetBrains products, that file is better used for binaries and libraries and autogen contents.

2 - Intellij keeps updating their projects and the files inside .idea keep changing every significant release from JB. What this means is we have to keep updating our .gitignore accordingly which is not an ideal use of time.

3 - Intellij has the flawed pattern here, most editors Atom, VS Code, Eclipse... nobody stores their IDE contents right inside project root. JB shouldn't be an exception either. It's the onus of Jetbrains to keep those files tracked outside project root. They have to refrain from polluting VCS root. This approach does just that. The .idea folder is kept outside the PROJECT_ROOT

Hope this helps.

Your values object is obviously an Object[] containing a String[] containing the values.

String[] stringValues = (String[])values[0];

You will not able to convert it into data frame until you use implicit conversion.

val sqlContext = new SqlContext(new SparkContext())

import sqlContext.implicits._

After this only you can convert this to data frame

case class Test(id:String,filed2:String)

val myFile = sc.textFile("file.txt")

val df= myFile.map( x => x.split(";") ).map( x=> Test(x(0),x(1)) ).toDF()

I could advise you to use Exp4j. It is easy to understand as you can see from the following example code:

Expression e = new ExpressionBuilder("3 * sin(y) - 2 / (x - 2)")
    .variables("x", "y")
    .build()
    .setVariable("x", 2.3)
    .setVariable("y", 3.14);
double result = e.evaluate();

NB This answer is factually incorrect; as pointed out by a comment below, success() does return the original promise. I'll not change; and leave it to OP to edit.

The major difference between the 2 is that .then() call returns a promise (resolved with a value returned from a callback) while .success() is more traditional way of registering callbacks and doesn't return a promise.

Promise-based callbacks (.then()) make it easy to chain promises (do a call, interpret results and then do another call, interpret results, do yet another call etc.).

The .success() method is a streamlined, convenience method when you don't need to chain call nor work with the promise API (for example, in routing).

In short:

• .then() - full power of the promise API but slightly more verbose
• .success() - doesn't return a promise but offeres slightly more convienient syntax

For mocking static functions i was able to do it that way:

• create a wrapper function in some helper class/object. (using a name variant might be beneficial for keeping things separated and maintainable.)
• use this wrapper in your codes. (Yes, codes need to be realized with testing in mind.)
• mock the wrapper function.

wrapper code snippet (not really functional, just for illustration)

class myWrapperClass ...
    def myWrapperFunction (...) {
        return theOriginalFunction (...)
    }

of course having multiple such functions accumulated in a single wrapper class might be beneficial in terms of code reuse.

Here comes Linq:

var listItem = list.Single(i => i.Title == title);

It throws an exception if there's no item matching the predicate. Alternatively, there's SingleOrDefault.

If you want a collection of items matching the title, there's:

var listItems = list.Where(i => i.Title ==  title);

You can do the same on document ready event like below

<script>
$(document).ready(function(){
 var number = 112;
    $("yourClass/Element/id...").html(number);
// $("yourClass/Element/id...").text(number);
});
</script>

or you can simply do it using document.write(number);.

With the directory on the classpath, from a class loaded by the same classloader, you should be able to use either of:

// From ClassLoader, all paths are "absolute" already - there's no context
// from which they could be relative. Therefore you don't need a leading slash.
InputStream in = this.getClass().getClassLoader()
                                .getResourceAsStream("SomeTextFile.txt");
// From Class, the path is relative to the package of the class unless
// you include a leading slash, so if you don't want to use the current
// package, include a slash like this:
InputStream in = this.getClass().getResourceAsStream("/SomeTextFile.txt");

If those aren't working, that suggests something else is wrong.

So for example, take this code:

package dummy;

import java.io.*;

public class Test
{
    public static void main(String[] args)
    {
        InputStream stream = Test.class.getResourceAsStream("/SomeTextFile.txt");
        System.out.println(stream != null);
        stream = Test.class.getClassLoader().getResourceAsStream("SomeTextFile.txt");
        System.out.println(stream != null);
    }
}

And this directory structure:

code
    dummy
          Test.class
txt
    SomeTextFile.txt

And then (using the Unix path separator as I'm on a Linux box):

java -classpath code:txt dummy.Test

Results:

true
true

Apparently, gcc doesn't behave like the one described in The C Programming language

It does in general. For your program to run on Windows it needs to end in .exe, "the C Programming language" was not written with Windows programmers in mind. As you've seen, cygwin emulates many, but not all, features of a POSIX environment.

If you don't want to repeat the list twice (as per @J W's answer), then put the updates in a table variable and use a JOIN in the UPDATE:

declare @ToDo table (FromName varchar(10), ToName varchar(10))
insert into @ToDo(FromName,ToName) values
 ('AAA','BBB'),
 ('CCC','DDD'),
 ('EEE','FFF')

update ts set LastName = ToName
from dbo.TestStudents ts
       inner join
     @ToDo t
       on
         ts.LastName = t.FromName

var scrollBottom =
    $(document).height() - $(window).height() - $(window).scrollTop();

I think it is better to get bottom scroll.

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

If you only need to exclude out enter, escape and spacebar keys, you can do the following:

$("#text1").keyup(function(event) {
if (event.keyCode != '13' && event.keyCode != '27' && event.keyCode != '32') {
     alert('test');
   }
});

See it actions here.

Newer versions of Python for Windows come with the pip package manager. (source)

pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4

Use that to install packages:

cd C:\Python\Scripts\
pip.exe install <package-name>

So in your case it'd be:

pip.exe install mechanize

I see some people prefer to generate sources into the target via jaxws-maven-plugin AND make this classes visible in source via build-helper-maven-plugin. As an argument for this structure

the version management system (svn/etc.) would always notice changed sources

With git it is not true. So you can just configure jaxws-maven-plugin to put them into your sources, but not under the target folder. Next time you build your project, git will not mark these generated files as changed. Here is the simple solution with only one plugin:

      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>jaxws-maven-plugin</artifactId>
        <version>2.6</version>

    <dependencies>
      <dependency>
        <groupId>org.jvnet.jaxb2_commons</groupId>
        <artifactId>jaxb2-fluent-api</artifactId>
        <version>3.0</version>
      </dependency>
      <dependency>
        <groupId>com.sun.xml.ws</groupId>
        <artifactId>jaxws-tools</artifactId>
        <version>2.3.0</version>
      </dependency>
    </dependencies>

    <executions>
      <execution>
        <goals>
          <goal>wsimport</goal>
        </goals>
        <configuration>
          <packageName>som.path.generated</packageName>
          <xjcArgs>
            <xjcArg>-Xfluent-api</xjcArg>
          </xjcArgs>
          <verbose>true</verbose>
          <keep>true</keep> <!--used by default-->
          <sourceDestDir>${project.build.sourceDirectory}</sourceDestDir>
          <wsdlDirectory>src/main/resources/META-INF/wsdl</wsdlDirectory>
          <wsdlLocation>META-INF/wsdl/soap.wsdl</wsdlLocation>
        </configuration>
      </execution>
    </executions>
  </plugin>

Additionally (just to note) in this example SOAP classes are generated with Fluent API, so you can create them like:

A a = new A()
  .withField1(value1)
  .withField2(value2);

Does it open correctly when you run "explorer.exe c:\teste" from your start menu? How long have you been trying this? I see a similar behavior when my machine has a lot of processes and when I open a new process(sets say IE)..it starts in the task manager but does not show up in the front end. Have you tried a restart?

The following code should open a new explorer instance

class sample{

static void Main()
{
  System.Diagnostics.Process.Start("explorer.exe",@"c:\teste");
}
}

The answers in this topic are all great. However i'd like to propose another one. Most likely you have been given an api and want that into your c# project. Using Postman, you can setup and test the api call there and once it runs properly, you can simply click 'Code' and the request that you have been working on, is written to a c# snippet. like this:

var client = new RestClient("https://api.XXXXX.nl/oauth/token");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Authorization", "Basic   N2I1YTM4************************************jI0YzJhNDg=");
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddParameter("grant_type", "password");
request.AddParameter("username", "[email protected]");
request.AddParameter("password", "XXXXXXXXXXXXX");
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

The code above depends on the nuget package RestSharp, which you can easily install.

I encountered that error when I forgot to uncheck the Precompiled header from the additional options in the wizard after naming a new Win32 console application.

Because I don't need stdafx.h library, I removed it by going to Project menu, then click Properties or [name of our project] Properties or simply press Alt + F7. On the dropdownlist beside configuration, select All Configurations. Below that, is a tree node, click Configuration Properties, then C/C++. On the right pane, select Create/Use Precompiled Header, and choose Not using Precompiled Header.

That won't work in IE<9 though, however, you can make IEs support that using:

CSS3Pie

PIE makes Internet Explorer 6-8 capable of rendering several of the most useful CSS3 decoration features.

aView.frame = CGRectMake(100, 200, aView.frame.size.width, aView.frame.size.height);

There's also the function tags, a bit more flexible:

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<c:if test="${fn:length(list) > 0}">

And here's the tag documentation.

find /abs/path/ -name '*.js'

Edit: As Brian points out, add -type f if you want only plain files, and not directories, links, etc.

You need to add android:exported="true" to start service from ADB command line. Then your manifest looks something like this:

<!-- Service declared in manifest -->
<service
    android:name=".YourServiceName"
    android:exported="true"
    android:launchMode="singleTop">
    <intent-filter>
        <action android:name="com.your.package.name.YourServiceName"/>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</service> <!-- Note: Service is exported to start it using ADB command -->

And then from ADB

To start service:

adb shell am startservice com.your.package.name/.YourServiceName

To stop service (on Marshmallow):

adb shell am stopservice com.your.package.name/.YourServiceName

To stop service (on Jelly Bean):

adb shell am force-stop com.your.package.name

Java 7 support was added at build tools 19. You can now use features like the diamond operator, multi-catch, try-with-resources, strings in switches, etc. Add the following to your build.gradle.

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

Gradle 1.7+, Android gradle plugin 0.6.+ are required.

Note, that only try with resources require minSdkVersion 19. Other features works on previous platforms.

Try Collections.shuffle(list).If usage of this method is barred for solving the problem, then one can look at the actual implementation.

Graphical log viewers, while they might be very good for viewing log files, don't meet the need for a command line utility that can be incorporated into scripts (or batch files). Often such a simple and general-purpose command can be used as part of a specialized solution for a particular environment. Graphical methods don't lend themselves readily to such use.

int belongs to System.ValueType and cannot have null as a value. When dealing with databases or other types where the elements can have a null value, it might be useful to check if the element is null. That is when int? comes into play. int? is a nullable type which can have values ranging from -2147483648 to 2147483648 and null.

I hate PYTHONPATH. I find it brittle and annoying to set on a per-user basis (especially for daemon users) and keep track of as project folders move around. I would much rather set sys.path in the invoke scripts for standalone projects.

However sys.path.append isn't the way to do it. You can easily get duplicates, and it doesn't sort out .pth files. Better (and more readable): site.addsitedir.

And script.py wouldn't normally be the more appropriate place to do it, as it's inside the package you want to make available on the path. Library modules should certainly not be touching sys.path themselves. Instead, you'd normally have a hashbanged-script outside the package that you use to instantiate and run the app, and it's in this trivial wrapper script you'd put deployment details like sys.path-frobbing.

   ID="AutoCompleteExtender1" runat="server" FirstRowSelected="false">  
      </asp:AutoCompleteExtender>  

Now To auto populate from database :

public static List<string> GetCompletionList(string prefixText, int count)  
    {  
        return AutoFillProducts(prefixText);  

    }  

    private static List<string> AutoFillProducts(string prefixText)  
    {  
        using (SqlConnection con = new SqlConnection())  
        {  
            con.ConnectionString = ConfigurationManager.ConnectionStrings["Conn"].ConnectionString;  
            using (SqlCommand com = new SqlCommand())  
            {  
                com.CommandText = "select ProductName from ProdcutMaster where " + "ProductName like @Search + '%'";  
                com.Parameters.AddWithValue("@Search", prefixText);  
                com.Connection = con;  
                con.Open();  
                List<string> countryNames = new List<string>();  
                using (SqlDataReader sdr = com.ExecuteReader())  
                {  
                    while (sdr.Read())  
                    {  
                        countryNames.Add(sdr["ProductName"].ToString());  
                    }  
                }  
                con.Close();  
                return countryNames;  
            }  
        }  
    }  

Now:create a stored Procedure that fetches the Product details depending on the selected product from the Auto Complete Text Box.

Create Procedure GetProductDet  
(  
@ProductName varchar(50)    
)  
as  
begin  
Select BrandName,warranty,Price from ProdcutMaster where ProductName=@ProductName  
End   

Create a function name to get product details ::

private void GetProductMasterDet(string ProductName)  
    {  
        connection();  
        com = new SqlCommand("GetProductDet", con);  
        com.CommandType = CommandType.StoredProcedure;  
        com.Parameters.AddWithValue("@ProductName", ProductName);  
        SqlDataAdapter da = new SqlDataAdapter(com);  
        DataSet ds=new DataSet();  
        da.Fill(ds);  
        DataTable dt = ds.Tables[0];  
        con.Close();  
        //Binding TextBox From dataTable  
        txtbrandName.Text =dt.Rows[0]["BrandName"].ToString();  
        txtwarranty.Text = dt.Rows[0]["warranty"].ToString();  
        txtPrice.Text = dt.Rows[0]["Price"].ToString();   
    }

Auto post back should be true

<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>

Now, Just call this function

protected void TextBox1_TextChanged(object sender, EventArgs e)  
  {  
      //calling method and Passing Values  
      GetProductMasterDet(TextBox1.Text);  
  } 

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

You should really post:

1. The complete source code of your example
2. The actual result of it, not a summary

Here is my code, which works:

import socket, sys

def alert(msg):
    print >>sys.stderr, msg
    sys.exit(1)

(family, socktype, proto, garbage, address) = \
         socket.getaddrinfo("::1", "http")[0] # Use only the first tuple
s = socket.socket(family, socktype, proto)

try:
    s.connect(address) 
except Exception, e:
    alert("Something's wrong with %s. Exception type is %s" % (address, e))

When the server listens, I get nothing (this is normal), when it doesn't, I get the expected message:

Something's wrong with ('::1', 80, 0, 0). Exception type is (111, 'Connection refused')

if you're using NSNotificationCenter for updating your view, don't forget to send it from the main thread by calling dispatch_async:

dispatch_async(dispatch_get_main_queue(),^{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"my_notification" object:nil];
});

NEW ELEMENTS

As an addendum to the comprehensive answers above to highlight critical points if you want the click to attach to new elements:

1. elements selected by the first selector eg $("body") must exist at the time the declaration is made otherwise there is nothing to attach to.
2. you must use the three arguments in the .on() function including the valid selector for your target elements as the second argument.

tldr;

$ awk '{print $NF}' file.txt | paste -sd, | sed 's/,/, /g'

For a file like this

$ cat file.txt
The quick brown fox
jumps over
the lazy dog.

the given command will print

fox, over, dog.

How it works:

• awk '{print $NF}' : prints the last field of every line
• paste -sd, : reads stdin serially (-s, one file at a time) and writes fields comma-delimited (-d,)
• sed 's/,/, /g' : substitutes "," with ", " globally (for all instances)

Here's a short code that might help.

    <yourJFrameName> main = new <yourJFrameName>();    

    main.setVisible(true);
    this.dispose();

where...

main.setVisible(true);

will run the JFrame again.

this.dispose();

will terminate the running window.

import React from 'react';

class Counter extends React.Component{
    state = {
        count: 0,

    formatCount() {
        const {count} = this.state;
        // use a return statement here, it is a importent,
        return count === 0 ? 'Zero' : count;
    }
    render() {
        return(
          <React.Fragment>
              <span>{this.formatCount()}</span>
              <button type="button" className="btn btn-primary">Increment</button>

        );
    }
}

export default Counter;

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

The working example.

You could use Kernel#test:

test ?d, 'some directory'

it gets it's origins from https://ss64.com/bash/test.html you will notice bash test has this flag -d to test if a directory exists -d file True if file is a Directory. [[ -d demofile ]]

on first button add the following.

onclick="window.location.href='Students.html';"

similarly do the rest 2 buttons.

<input type="button" value="Add Students" onclick="window.location.href='Students.html';"> 
<input type="button" value="Add Courses" onclick="window.location.href='Courses.html';"> 
<input type="button" value="Student Payments" onclick="window.location.href='Payments.html';">

I tried with every answer avobe, but couldn't make it.

Did this and worked

sudo apt-get purge python-virtualenv
sudo pip install pip -U

After that I just installed virtualenv with pip

sudo pip install virtualenv

I built the virtualenv that I was working on and the package was installed easily. Get into the virtualenv by using source /bin/activate and try to install your package, for example:

pip install terminado

It worked for me, although I was using python2.7 not python3

If you have a newer version of the Anaconda Navigator, open the Anaconda Prompt program that came in the install. Type all the usual conda update/conda install commands there.

I think the answers above explain this, but I could have used a very simple instruction like this. Perhaps it will help others.

According to Extensible Messaging and Presence Protocol (Wikipedia), the standard TCP port for the server is 5222.

The client would presumably use the same ports as the messaging protocol, but can also use http (port 80) and https (port 443) for message delivery. These have the advantage of working for users behind firewalls, so your network admin should not need to get involved.

When your are trying to apply prod on string type of value like:

['-214' '-153' '-58' ..., '36' '191' '-37']

you will get the error.

Solution: Append only integer value like [1,2,3], and you will get your expected output.

If the value is in string format before appending then, in the array you can convert the type into int type and store it in a list.

Maybe this trick gives u an idea

Boolean var= new anonymousClass(){
    private String myVar; //String for example
    @Overriden public Boolean method(int i){
          //use myVar and i
    }
    public String setVar(String var){myVar=var; return this;} //Returns self instane
}.setVar("Hello").method(3);

In addition to qqplots and the Shapiro-Wilk test, the following methods may be useful.

Qualitative:

• histogram compared to the normal
• cdf compared to the normal
• ggdensity plot
• ggqqplot

Quantitative:

• nortest package normality tests
• normtest package normality tests

The qualitive methods can be produced using the following in R:

library("ggpubr")
library("car")

h <- hist(data, breaks = 10, density = 10, col = "darkgray") 
xfit <- seq(min(data), max(data), length = 40) 
yfit <- dnorm(xfit, mean = mean(data), sd = sd(data)) 
yfit <- yfit * diff(h$mids[1:2]) * length(data) 
lines(xfit, yfit, col = "black", lwd = 2)

plot(ecdf(data), main="CDF")
lines(ecdf(rnorm(10000)),col="red")

ggdensity(data)

ggqqplot(data)

A word of caution - don't blindly apply tests. Having a solid understanding of stats will help you understand when to use which tests and the importance of assumptions in hypothesis testing.

Short, portable and declared in stdio.h

stdin = freopen(NULL,"r",stdin);

Doesn't get hung in an infinite loop when there is nothing on stdin to flush like the following well know line:

while ((c = getchar()) != '\n' && c != EOF) { }

A little expensive so don't use it in a program that needs to repeatedly clear the buffer.

Stole from a coworker :)

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }
};

yymmdd Function

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

You can use this code: You shouldn't use this code:

byte[] bytes = streamReader.CurrentEncoding.GetBytes(streamReader.ReadToEnd());

Please see the comment to this answer as to why. I will leave the answer, so people know about the problems with this approach, because I didn't up till now.

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):

select myintfield + 0.0 as myfloatfield from mytable

While @Heximal's answer works, I don't personally recommend it.

This is because it uses implicit casting. Although you didn't type CAST, either the SUM() or the 0.0 need to be cast to be the same data-types, before the + can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +. But SUM(aFloatField) + 0 does not yield an INT, because the 0 is being implicitly cast to a FLOAT.

I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.

If you want to be explicit, I would use the following.

CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT  requires 8.0

You can try the following to see what happens...

CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))

Update for 2020 - BinaryPrimitives should now be preferred over BitConverter. It provides endian-specific APIs, and is less allocatey.

byte[] bytes = BitConverter.GetBytes(i);

although note also that you might want to check BitConverter.IsLittleEndian to see which way around that is going to appear!

Note that if you are doing this repeatedly you might want to avoid all those short-lived array allocations by writing it yourself via either shift operations (>> / <<), or by using unsafe code. Shift operations also have the advantage that they aren't affected by your platform's endianness; you always get the bytes in the order you expect them.

This question is 12 years old but it still needs to be given a better answer. As few noted in the comments and contrarily to what all answers pretend it would certainly make sense to have static abstract methods in C#. As philosopher Daniel Dennett put it, a failure of imagination is not an insight into necessity. There is a common mistake in not realizing that C# is not only an OOP language. A pure OOP perspective on a given concept leads to a restricted and in the current case misguided examination. Polymorphism is not only about subtying polymorphism: it also includes parametric polymorphism (aka generic programming) and C# has been supporting this for a long time now. Within this additional paradigm, abstract classes (and most types) are not only used to type instances. They can also be used as bounds for generic parameters; something that has been understood by users of certain languages (like for example Haskell, but also more recently Scala, Rust or Swift) for years.

In this context you may want to do something like this:

void Catch<TAnimal>() where TAnimal : Animal
{
    string scientificName = TAnimal.ScientificName; // abstract static property
    Console.WriteLine($"Let's catch some {scientificName}");
    …
}

And here the capacity to express static members that can be specialized by subclasses totally makes sense!

Unfortunately C# does not allow abstract static members but I'd like to propose a pattern that can emulate them reasonably well. This pattern is not perfect (it imposes some restrictions on inheritance) but as far as I can tell it is typesafe.

The main idea is to associate an abstract companion class (here SpeciesFor<TAnimal>) to the one that should contain abstract members (here Animal):

public abstract class SpeciesFor<TAnimal> where TAnimal : Animal
{
    public static SpeciesFor<TAnimal> Instance { get { … } }

    // abstract "static" members

    public abstract string ScientificName { get; }
    
    …
}

public abstract class Animal { … }

Now we would like to make this work:

void Catch<TAnimal>() where TAnimal : Animal
{
    string scientificName = SpeciesFor<TAnimal>.Instance.ScientificName;
    Console.WriteLine($"Let's catch some {scientificName}");
    …
}

Of course we have two problems to solve:

1. How do we allow and force an implementer of a subclass of Animal to associate a specific instance of SpeciesFor<TAnimal> to this subclass?
2. How does the property SpeciesFor<TAnimal>.Instance retrieve this information?

Here is how we can solve 1:

public abstract class Animal<TSelf> where TSelf : Animal<TSelf>
{
    private Animal(…) {}
    
    public abstract class OfSpecies<TSpecies> : Animal<TSelf>
        where TSpecies : SpeciesFor<TSelf>, new()
    {
        protected OfSpecies(…) : base(…) { }
    }
    
    …
}

By making the constructor of Animal<TSelf> private we make sure that all its subclasses are also subclasses of inner class Animal<TSelf>.OfSpecies<TSpecies>. So these subclasses must specify a TSpecies type that has a new() bound.

For 2 we can provide the following implementation:

public abstract class SpeciesFor<TAnimal> where TAnimal : Animal<TAnimal>
{
    private static SpeciesFor<TAnimal> _instance;

    public static SpeciesFor<TAnimal> Instance => _instance ??= MakeInstance();

    private static SpeciesFor<TAnimal> MakeInstance()
    {
        Type t = typeof(TAnimal);
        while (true)
        {
            if (t.IsConstructedGenericType
                    && t.GetGenericTypeDefinition() == typeof(Animal<>.OfSpecies<>))
                return (SpeciesFor<TAnimal>)Activator.CreateInstance(t.GenericTypeArguments[1]);
            t = t.BaseType;
            if (t == null)
                throw new InvalidProgramException();
        }
    }

    // abstract "static" members

    public abstract string ScientificName { get; }
    
    …
}

How can we be sure that the reflection code inside MakeInstance() never throws? As we've already said, almost all classes within the hierarchy of Animal<TSelf> are also subclasses of Animal<TSelf>.OfSpecies<TSpecies>. So we know that for these classes a specific TSpecies must be provided. This type is also necessarily constructible thanks to constraint : new(). But this still leaves abstract types like Animal<Something> that have no associated species. Now we can convince ourself that the curiously recurring template pattern where TAnimal : Animal<TAnimal> makes it impossible to write SpeciesFor<Animal<Something>>.Instance as type Animal<Something> is never a subtype of Animal<Animal<Something>>.

Et voilà:

public class CatSpecies : SpeciesFor<Cat>
{
    // overriden "static" members

    public override string ScientificName => "Felis catus";
    public override Cat CreateInVivoFromDnaTrappedInAmber() { … }
    public override Cat Clone(Cat a) { … }
    public override Cat Breed(Cat a1, Cat a2) { … }
}

public class Cat : Animal<Cat>.OfSpecies<CatSpecies>
{
    // overriden members

    public override string CuteName { get { … } }
}

public class DogSpecies : SpeciesFor<Dog>
{
    // overriden "static" members

    public override string ScientificName => "Canis lupus familiaris";
    public override Dog CreateInVivoFromDnaTrappedInAmber() { … }
    public override Dog Clone(Dog a) { … }
    public override Dog Breed(Dog a1, Dog a2) { … }
}

public class Dog : Animal<Dog>.OfSpecies<DogSpecies>
{
    // overriden members

    public override string CuteName { get { … } }
}

public class Program
{
    public static void Main()
    {
        ConductCrazyScientificExperimentsWith<Cat>();
        ConductCrazyScientificExperimentsWith<Dog>();
        ConductCrazyScientificExperimentsWith<Tyranosaurus>();
        ConductCrazyScientificExperimentsWith<Wyvern>();
    }
    
    public static void ConductCrazyScientificExperimentsWith<TAnimal>()
        where TAnimal : Animal<TAnimal>
    {
        // Look Ma! No animal instance polymorphism!
        
        TAnimal a2039 = SpeciesFor<TAnimal>.Instance.CreateInVivoFromDnaTrappedInAmber();
        TAnimal a2988 = SpeciesFor<TAnimal>.Instance.CreateInVivoFromDnaTrappedInAmber();
        TAnimal a0400 = SpeciesFor<TAnimal>.Instance.Clone(a2988);
        TAnimal a9477 = SpeciesFor<TAnimal>.Instance.Breed(a0400, a2039);
        TAnimal a9404 = SpeciesFor<TAnimal>.Instance.Breed(a2988, a9477);
        
        Console.WriteLine(
            "The confederation of mad scientists is happy to announce the birth " +
            $"of {a9404.CuteName}, our new {SpeciesFor<TAnimal>.Instance.ScientificName}.");
    }
}

A limitation of this pattern is that it is not possible (as far as I can tell) to extend the class hierarchy in a satifying manner. For example we cannot introduce an intermediary Mammal class associated to a MammalClass companion. Another is that it does not work for static members in interfaces which would be more flexible than abstract classes.

In the <system.web> element, add the following element:

<httpCookies requireSSL="true" />

However, if you have a <forms> element in your system.web\authentication block, then this will override the setting in httpCookies, setting it back to the default false.

In that case, you need to add the requireSSL="true" attribute to the forms element as well.

So you will end up with:

<system.web>
    <authentication mode="Forms">
        <forms requireSSL="true">
            <!-- forms content -->
        </forms>
    </authentication>
</system.web>

See here and here for MSDN documentation of these elements.

Press Command+Shift+4 and then keep the mouse pointer on Simulator and then press "Space Bar" key one camera icon will appear, now left click the mouse. Your simulator screen shot is saved on desktop. You can take the screen shot any small screen in the same way.

The best way I found is to use another class. You can create an object and then use it on other objects.

class staticFlag:
    def __init__(self):
        self.__success = False
    def isSuccess(self):
        return self.__success
    def succeed(self):
        self.__success = True

class tryIt:
    def __init__(self, staticFlag):
        self.isSuccess = staticFlag.isSuccess
        self.succeed = staticFlag.succeed

tryArr = []
flag = staticFlag()
for i in range(10):
    tryArr.append(tryIt(flag))
    if i == 5:
        tryArr[i].succeed()
    print tryArr[i].isSuccess()

With the example above, I made a class named staticFlag.

This class should present the static var __success (Private Static Var).

tryIt class represented the regular class we need to use.

Now I made an object for one flag (staticFlag). This flag will be sent as reference to all the regular objects.

All these objects are being added to the list tryArr.

This Script Results:

False
False
False

If anyone like me is searching to read only a specific line, example only line 18 here is the code:

filename = "C:\log.log"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

For i = 1 to 17
    f.ReadLine
Next

strLine = f.ReadLine
Wscript.Echo strLine

f.Close

For your specific example, if you want to do a one-to-one relationship, you should change the next code in ReleaseDateType model:

@Column(nullable = true) 
private Integer media_Id;

for:

@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name="CACHE_MEDIA_ID", nullable=true)
private CacheMedia cacheMedia ;

and in CacheMedia model you need to add:

@OneToOne(cascade=ALL, mappedBy="ReleaseDateType")
private ReleaseDateType releaseDateType;

then in your repository you should replace:

@Query("Select * from A a  left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();

by:

//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedia_Id(Integer id); 

or by:

@Query("FROM ReleaseDateType AS rdt WHERE cm.rdt.cacheMedia.id = ?1")    //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);

Or if you prefer to do a @OneToMany and @ManyToOne relation, you should change the next code in ReleaseDateType model:

@Column(nullable = true) 
private Integer media_Id;

for:

@OneToMany(cascade=ALL, mappedBy="ReleaseDateType")
private List<CacheMedia> cacheMedias ;

and in CacheMedia model you need to add:

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="RELEASE_DATE_TYPE_ID", nullable=true)
private ReleaseDateType releaseDateType;

then in your repository you should replace:

@Query("Select * from A a  left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();

by:

//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedias_Id(Integer id); 

or by:

@Query("FROM ReleaseDateType AS rdt LEFT JOIN rdt.cacheMedias AS cm WHERE cm.id = ?1")    //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);

Python is only a language, to get GET and POST data, you need a web framework or toolkit written in Python. Django is one, as Charlie points out, the cgi and urllib standard modules are others. Also available are Turbogears, Pylons, CherryPy, web.py, mod_python, fastcgi, etc, etc.

In Django, your view functions receive a request argument which has request.GET and request.POST. Other frameworks will do it differently.

• you can also indent a whole section by selecting it and clicking TAB
• and also indent backward using Shift+TAB

And of course for auto indentation and formatting, following the language you're using, you can see which good extensions do the good job, and which formatters to install or which parameters settings to enable or set for each language and its available tools. Just make sure to read well the documentation of the extension, to install and set all what it need.

Up to now the indentation problem bothers me with Python when copy pasting a block of code. If that's the case, here is how you solve that: Visual Studio Code indentation for Python

For some reason, none of the above worked for me. This DID however:

1. Selected the range of cells I needed to replace.
2. Go to Home > Find & Select > Replace or Ctrl + H
3. Find what: ,
4. Replace with: CTRL + SHIFT + J
5. Click Replace All

Somehow CTRL + SHIFT + J is registered as a linebreak.

from the pandas doc http://pandas.pydata.org/pandas-docs/stable/dsintro.html Series is a one-dimensional labeled array capable of holding any data type. To read data in form of panda Series:

import pandas as pd
ds = pd.Series(data, index=index)

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types.

import pandas as pd
df = pd.DataFrame(data, index=index)

In both of the above index is list

for example: I have a csv file with following data:

,country,popuplation,area,capital
BR,Brazil,10210,12015,Brasile
RU,Russia,1025,457,Moscow
IN,India,10458,457787,New Delhi

To read above data as series and data frame:

import pandas as pd
file_data = pd.read_csv("file_path", index_col=0)
d = pd.Series(file_data.country, index=['BR','RU','IN'] or index =  file_data.index)

output:

>>> d
BR           Brazil
RU           Russia
IN            India

df = pd.DataFrame(file_data.area, index=['BR','RU','IN'] or index = file_data.index )

output:

>>> df
      area
BR   12015
RU     457
IN  457787

If you are using c# on the desktop, you can use SimpleMapi. That way it will be sent using the default mail client, and the user has the option of reviewing the message before sending, just like mailto:.

To use it you add the Simple-MAPI.NET package (it's 13Kb), and run:

var mapi = new SimpleMapi();
mapi.AddRecipient(null, address, false);
mapi.Attach(path);
//mapi.Logon(ParentForm.Handle);    //not really necessary
mapi.Send(subject, body, true);

use android:layout_gravity instead of android:gravity

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

Easy:

print my_queryset.query

For example:

from django.contrib.auth.models import User
print User.objects.filter(last_name__icontains = 'ax').query

It should also be mentioned that if you have DEBUG = True, then all of your queries are logged, and you can get them by accessing connection.queries:

from django.db import connections
connections['default'].queries

The django debug toolbar project uses this to present the queries on a page in a neat manner.

In many cases, particularly with text classification it is not enough just to store the classifier but you'll need to store the vectorizer as well so that you can vectorize your input in future.

import pickle
with open('model.pkl', 'wb') as fout:
  pickle.dump((vectorizer, clf), fout)

future use case:

with open('model.pkl', 'rb') as fin:
  vectorizer, clf = pickle.load(fin)

X_new = vectorizer.transform(new_samples)
X_new_preds = clf.predict(X_new)

Before dumping the vectorizer, one can delete the stop_words_ property of vectorizer by:

vectorizer.stop_words_ = None

to make dumping more efficient. Also if your classifier parameters is sparse (as in most text classification examples) you can convert the parameters from dense to sparse which will make a huge difference in terms of memory consumption, loading and dumping. Sparsify the model by:

clf.sparsify()

Which will automatically work for SGDClassifier but in case you know your model is sparse (lots of zeros in clf.coef_) then you can manually convert clf.coef_ into a csr scipy sparse matrix by:

clf.coef_ = scipy.sparse.csr_matrix(clf.coef_)

and then you can store it more efficiently.

In xml edittext:

android:id="@+id/text"

In program:

EditText text=(EditText) findViewById(R.id.text);
text.setRawInputType(Configuration.KEYBOARDHIDDEN_YES);

I am surprised why there is not a CrytpoGraphic solution in place. GUID is unique but not cryptographically safe. See this Dotnet Fiddle.

var bytes = new byte[40]; // byte size
using (var crypto = new RNGCryptoServiceProvider())
  crypto.GetBytes(bytes);

var base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

In case you want to Prepend with a Guid:

var result = Guid.NewGuid().ToString("N") + base64;
Console.WriteLine(result);

A cleaner alphanumeric string:

result = Regex.Replace(result,"[^A-Za-z0-9]","");
Console.WriteLine(result);

Watch out for possible unintended literals in your argument

for example you can have a space within your argument, rendering it to a string / literal:

float(' 0.33')

After making sure the unintended space did not make it into the argument, I was left with:

float(0.33) 

Like this it works like a charm.

Take away is: Pay Attention for unintended literals (e.g. spaces that you didn't see) within your input.

By adding using System.Timers; to your program you can use this function:

private static void delay(int Time_delay)
{
   int i=0;
  //  ameTir = new System.Timers.Timer();
    _delayTimer = new System.Timers.Timer();
    _delayTimer.Interval = Time_delay;
    _delayTimer.AutoReset = false; //so that it only calls the method once
    _delayTimer.Elapsed += (s, args) => i = 1;
    _delayTimer.Start();
    while (i == 0) { };
}

Delay is a function and can be used like:

delay(5000);

Some times eclipse may confuse with other projects in the same directory.

Just change package name (don't forget to change in Android manifest file also), ensure the package name is not used already in the directory. It may work.

Some devices don't provide the orientationchange event, but do fire the window's resize event:

// Listen for resize changes
window.addEventListener("resize", function() {
    // Get screen size (inner/outerWidth, inner/outerHeight)

}, false);

A bit less obvious than the orientationchange event, but works very well. Please check here

This is my nginx config file and iosocket code. Server(express) is listening on port 9191. It works well: nginx config file:

server {
    listen       443 ssl;
    server_name  localhost;
    root   /usr/share/nginx/html/rdist;

    location /user/ {
        proxy_pass   http://localhost:9191;
    }
    location /api/ {
        proxy_pass   http://localhost:9191;
    }
    location /auth/ {
        proxy_pass   http://localhost:9191;
    }

    location / {
        index  index.html index.htm;
        if (!-e $request_filename){
          rewrite ^(.*)$ /index.html break;
        }
    }
    location /socket.io/ {
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_pass   http://localhost:9191/socket.io/;
    }


    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    ssl_certificate /etc/nginx/conf.d/sslcert/xxx.pem;
    ssl_certificate_key /etc/nginx/conf.d/sslcert/xxx.key;

}

Server:

const server = require('http').Server(app)
const io = require('socket.io')(server)
io.on('connection', (socket) => {
    handleUserConnect(socket)

  socket.on("disconnect", () => {
   handleUserDisConnect(socket)
  });
})

server.listen(9191, function () {
  console.log('Server listening on port 9191')
})

Client(react):

    const socket = io.connect('', { secure: true, query: `userId=${this.props.user._id}` })

        socket.on('notifications', data => {
            console.log('Get messages from back end:', data)
            this.props.mergeNotifications(data)
        })

As another example of its use:

If you have an RSS Feed (xml document) and want to include some basic HTML encoding in the display of the description, you can use CData to encode it:

<item>
  <title>Title of Feed Item</title>
  <link>/mylink/article1</link>
  <description>
    <![CDATA[
      <p>
      <a href="/mylink/article1"><img style="float: left; margin-right: 5px;" height="80" src="/mylink/image" alt=""/></a>
      Author Names
      <br/><em>Date</em>
      <br/>Paragraph of text describing the article to be displayed</p>
    ]]>
  </description>
</item>

The RSS Reader pulls in the description and renders the HTML within the CDATA.

Note - not all HTML tags work - I think it depends on the RSS reader you are using.

And as a explanation for why this example uses CData (and not the appropriate pubData and dc:creator tags): this is for website display using a RSS widget for which we have no real formatting control.

This enables us to specify the height and position of the included image, format the author names and date correctly, and so forth, without the need for a new widget. It also means I can script this and not have to add them by hand.

The accepted answer works only if you want exactly 31 days later. That means if you are using the date "2013-05-31" that you expect to not be in June which is not what I wanted.

If you want to have the next month, I suggest you to use the current year and month but keep using the 1st.

$date = date("Y-m-01");
$newdate = strtotime ( '+1 month' , strtotime ( $date ) ) ;

This way, you will be able to get the month and year of the next month without having a month skipped.

The to_dict() method sets the column names as dictionary keys so you'll need to reshape your DataFrame slightly. Setting the 'ID' column as the index and then transposing the DataFrame is one way to achieve this.

to_dict() also accepts an 'orient' argument which you'll need in order to output a list of values for each column. Otherwise, a dictionary of the form {index: value} will be returned for each column.

These steps can be done with the following line:

>>> df.set_index('ID').T.to_dict('list')
{'p': [1, 3, 2], 'q': [4, 3, 2], 'r': [4, 0, 9]}

In case a different dictionary format is needed, here are examples of the possible orient arguments. Consider the following simple DataFrame:

>>> df = pd.DataFrame({'a': ['red', 'yellow', 'blue'], 'b': [0.5, 0.25, 0.125]})
>>> df
        a      b
0     red  0.500
1  yellow  0.250
2    blue  0.125

Then the options are as follows.

dict - the default: column names are keys, values are dictionaries of index:data pairs

>>> df.to_dict('dict')
{'a': {0: 'red', 1: 'yellow', 2: 'blue'}, 
 'b': {0: 0.5, 1: 0.25, 2: 0.125}}

list - keys are column names, values are lists of column data

>>> df.to_dict('list')
{'a': ['red', 'yellow', 'blue'], 
 'b': [0.5, 0.25, 0.125]}

series - like 'list', but values are Series

>>> df.to_dict('series')
{'a': 0       red
      1    yellow
      2      blue
      Name: a, dtype: object, 

 'b': 0    0.500
      1    0.250
      2    0.125
      Name: b, dtype: float64}

split - splits columns/data/index as keys with values being column names, data values by row and index labels respectively

>>> df.to_dict('split')
{'columns': ['a', 'b'],
 'data': [['red', 0.5], ['yellow', 0.25], ['blue', 0.125]],
 'index': [0, 1, 2]}

records - each row becomes a dictionary where key is column name and value is the data in the cell

>>> df.to_dict('records')
[{'a': 'red', 'b': 0.5}, 
 {'a': 'yellow', 'b': 0.25}, 
 {'a': 'blue', 'b': 0.125}]

index - like 'records', but a dictionary of dictionaries with keys as index labels (rather than a list)

>>> df.to_dict('index')
{0: {'a': 'red', 'b': 0.5},
 1: {'a': 'yellow', 'b': 0.25},
 2: {'a': 'blue', 'b': 0.125}}

Because one moderator deleted my detailed image-supported answer on this question, just because I copied and pasted from another question, I am forced to put a less detailed answer and I will link the original answer if you want a more visual way to see the solution.

For Visual Studio 2019 and Visual Studio 2017 Users
For People who are missing this old feature in VS2019 (or maybe VS2017) from the old versions of Visual Studio

This feature still available, but it is NOT available by default, you have to install it separately.

1. Open VS 2019 go to Tools -> Get Tools and Features
2. Select the Individual components tab and search for Class Designer
3. Select this Component and Install it, After finish installing this component (you may need to restart visual studio)
4. Right-click on the project and select Add -> Add New Item
5. Search for 'class' word and NOW you can see Class Diagram component

see this answer also to see an image associated

Update to create a class-diagram for the whole project
I received a downvote because I did not mention how to generate a diagram for the whole project, here is how to do it (after applying the previous steps)

1. Add class diagram to the project
2. if the option Preview Selected Items is enabled in the solution explorer, disabled it temporarily, you can re-enable it later

3. open the class diagram that you created in step 2 (by double-clicking on it)
4. drag-and-drop the project from the solution explorer to the class diagram

you could be shocked by the results to the point that you can change your mind and remove your downvote (please do NOT upvote, it is enough to remove your downvote)

Or, if you want to use minimal "powers" (e.g. if you don't want a cascade delete) to achieve what you want, use

import org.hibernate.annotations.Cascade;
import org.hibernate.annotations.CascadeType;

...

@Cascade({CascadeType.SAVE_UPDATE})
private Set<Child> children;

I don't mention basics like syntax highlighting as I expect these by default.

This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.

PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

You shouldn't design your application based on specific lifetimes of access tokens. Just assume they are (very) short lived.

However, after a successful completion of the OAuth2 installed application flow, you will get back a refresh token. This refresh token never expires, and you can use it to exchange it for an access token as needed. Save the refresh tokens, and use them to get access tokens on-demand (which should then immediately be used to get access to user data).

EDIT: My comments above notwithstanding, there are two easy ways to get the access token expiration time:

1. It is a parameter in the response (expires_in)when you exchange your refresh token (using /o/oauth2/token endpoint). More details.

2. There is also an API that returns the remaining lifetime of the access_token:

   https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={accessToken}

   This will return a json array that will contain an expires_in parameter, which is the number of seconds left in the lifetime of the token.

RewriteEngine On

RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule ^.*$ https://%1/$1 [R=301,L]

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

This worked for me after much trial and error. Part one is from the user above and will capture www.xxx.yyy and send to https://xxx.yyy

Part 2 looks at entered URL and checks if HTTPS, if not, it sends to HTTPS

Done in this order, it follows logic and no error occurs.

@Primary annotation when used against a method like below works good if the two data sources are on the same db location/server.

@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
  return DataSourceBuilder.create().build();
}

@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
  return DataSourceBuilder.create().build();
}

If the data sources are on different servers its better to use @Component along with @Primary annotation. The following code snippet works well on two different data sources at different locations

database1.datasource.url = jdbc:mysql://127.0.0.1:3306/db1
database1.datasource.username = root
database1.datasource.password = mysql
database1.datasource.driver-class-name=com.mysql.jdbc.Driver

database2.datasource1.url = jdbc:mysql://192.168.113.51:3306/db2
database2.datasource1.username = root
database2.datasource1.password = mysql
database2.datasource1.driver-class-name=com.mysql.jdbc.Driver

@Configuration
@Primary
@Component
@ComponentScan("com.db1.bean")
class DBConfiguration1{
    @Bean("db1Ds")
    @ConfigurationProperties(prefix="database1.datasource")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

}

@Configuration
@Component
@ComponentScan("com.db2.bean")
class DBConfiguration2{
    @Bean("db2Ds")
    @ConfigurationProperties(prefix="database2.datasource1")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

}

Here's a hack that just got me out of trouble with this one.

So a similar scenario to the OP - I've got a nested Angular component that needs data passed down to it, but the input points to an array, and as mentioned above, Angular doesn't see a change as it does not examine the contents of the array.

So to fix it I convert the array to a string for Angular to detect a change, and then in the nested component I split(',') the string back to an array and its happy days again.

I had the same problem. I restarted Visual Studio and that fixed the problem

<form method="POST">
    <button name="data" onclick="getData()">Click</button>
</form>

instead of using button tag, use input tag. Like this,

<form method="POST">
    <input type = "button" name="data" onclick="getData()" value="Click">
</form>

For everyone struggling with this issue, you simply need to upgrade your openssl installation. I'm running windows 10, installed the latest anaconda 64-bit and am getting this error when I try to install/upgrade anything with 'conda' or 'pip'. If I uninstall the 64-bit anaconda and install the 32-bit, it works fine. I had a 64-bit version of openssl for windows installed, version 1.1.0 something. I uninstalled that and installed the latest I could find from here: https://slproweb.com/products/Win32OpenSSL.html -- there is a 64-bit version of 1.1.1 on there that worked. Now I can install packages via pip and conda successfully. Hope this helps.

The marked answer is the correct one. However, Pricey, you should follow up on this with your AD and desktop admin groups. They are misusing the IE11 Enterprise Mode site list. Microsoft does NOT intend it to be used for all intranet sites within an organization at all. That would be propagating the existing "render all intranet sites in compatibility mode" setting that is the bane of corporate website advancement the world over.

It's meant to implemented as a "Black list", with the handful of sites that actually require a legacy browser mode listed in the Enterprise Mode list with their rendering requirements specified. All other sites in your organization are then freed up to use Edge. The people in your organization who implemented it with all intranet sites included to start with have completely misunderstood how Enterprise Mode is meant to be implemented.

Someone may find it useful. You could put those locale settings in .bashrc file, which usually located in the home directory.
Just add this command in .bashrc:
export LC_ALL=C
then type source .bashrc
Now you don't need to call this command manually every time, when you connecting via ssh for example.

This is because require() does not exist in the browser/client-side JavaScript.

Now you're going to have to make some choices about your client-side JavaScript script management.

You have three options:

1. Use the <script> tag.
2. Use a CommonJS implementation. It has synchronous dependencies like Node.js
3. Use an asynchronous module definition (AMD) implementation.

CommonJS client side-implementations include (most of them require a build step before you deploy):

1. Browserify - You can use most Node.js modules in the browser. This is my personal favorite.
2. Webpack - Does everything (bundles JavaScript code, CSS, etc.). It was made popular by the surge of React, but it is notorious for its difficult learning curve.
3. Rollup - a new contender. It leverages ES6 modules and includes tree-shaking abilities (removes unused code).

You can read more about my comparison of Browserify vs (deprecated) Component.

AMD implementations include:

1. RequireJS - Very popular amongst client-side JavaScript developers. It is not my taste because of its asynchronous nature.

Note, in your search for choosing which one to go with, you'll read about Bower. Bower is only for package dependencies and is unopinionated on module definitions like CommonJS and AMD.

Thanks bhavya's solution.There have been two answers about swift, but those are not very intact. I have do that in the swift3.Below is the main code.

In AppDelegate.swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    // seclect the mainStoryBoard entry by whthere user is login.
    let userDefaults = UserDefaults.standard

    if let isLogin: Bool = userDefaults.value(forKey:Common.isLoginKey) as! Bool? {
        if (!isLogin) {
            self.window?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "LogIn")
        }
   }else {
        self.window?.rootViewController = mainStoryboard.instantiateViewController(withIdentifier: "LogIn")
   }

    return true
}

In SignUpViewController.swift

@IBAction func userLogin(_ sender: UIButton) {
    //handle your login work
    UserDefaults.standard.setValue(true, forKey: Common.isLoginKey)
    let delegateTemp = UIApplication.shared.delegate
    delegateTemp?.window!?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "Main")
}

In logOutAction function

@IBAction func logOutAction(_ sender: UIButton) {
    UserDefaults.standard.setValue(false, forKey: Common.isLoginKey)
    UIApplication.shared.delegate?.window!?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateInitialViewController()
}

It would depend on the browser's default stylesheet. You can view an (unofficial) table of CSS2.1 User Agent stylesheet defaults here.

Based on the page listed above, the default sizes look something like this:

    IE7     IE8     FF2         FF3         Opera   Safari 3.1
H1  24pt    2em     32px        32px        32px    32px       
H2  18pt    1.5em   24px        24px        24px    24px
H3  13.55pt 1.17em  18.7333px   18.7167px   18px    19px
H4  n/a     n/a     n/a         n/a         n/a     n/a
H5  10pt    0.83em  13.2667px   13.2833px   13px    13px
H6  7.55pt  0.67em  10.7333px   10.7167px   10px    11px

Also worth taking a look at is the default stylesheet for HTML 4. The W3C recommends using these styles as the default. An abridged excerpt:

h1 { font-size: 2em; }
h2 { font-size: 1.5em; }
h3 { font-size: 1.17em; }
h4 { font-size: 1.12em; }
h5 { font-size: .83em; }
h6 { font-size: .75em; }

Hope this information is helpful.

System: Ubuntu 16.04 LTS, yet you can try these steps in accordance to your respective systems.

If there is an SDK file present, it should be most likely found at /home/USERNAME/Android/sdk

USERNAME is to be replaced by your username

If there is none, check the specified sdk path for the project in android studio. File > Project Structure > sdk path

The sdk directory should be present in the specified path. In case, it is not there, open the file: PROJECT_DIRECTORY/android/local.properties

PROJECT_DIRECTORY needs to be replaced by your project name.

If the file is not there, create it. Then add the following line depending on where you find the sdk directory.

If sdk is there at /home/USERNAME/Android/: add the line: sdk.dir = /home/tanya/Android/sdk

If sdk is not there at /home/USERNAME/Android/: add the line: sdk.dir = /home/tanya/Android/

If the path specified for sdk directory in 'Project Structure' is entirely different and the sdk directory is present at the specified location, add the line: sdk.dir = SPECIFIED_SDK_PATH

Add the specified sdk path in place of SPECIFIED_SDK_PATH

try this

   SELECT group_name, employees, surveys, COUNT( surveys ) AS test1,

For Windows 8 users:

After trying every solution given here, with no success, I found this:

Go to Device Manager

Browse my computer for drivers -> Let me pick from a list of device drivers on my computer

Choose Android Device and then Android ADB Interface.

Now I have my devices listed at adb devices.

You can't add i tag in option tag because tags are stripped.

But you can add it after the select like this

If the goal is to seperate two elements, you can use CSS like below:

A<span style={{paddingLeft: '20px'}}>B</span>

Are you certain that the software (and not yourself, since your test actually only shows the shell used as default for your user) uses /bin/bash ?

This is the optimal way, I found, to do this:

private void GetSubArrayThroughArraySegment() {
  int[] array = { 10, 20, 30 };
  ArraySegment<int> segment = new ArraySegment<int>(array,  1, 2);
  Console.WriteLine("-- Array --");
  int[] original = segment.Array;
  foreach (int value in original)
  {
    Console.WriteLine(value);
  }
  Console.WriteLine("-- Offset --");
  Console.WriteLine(segment.Offset);
  Console.WriteLine("-- Count --");
  Console.WriteLine(segment.Count);

  Console.WriteLine("-- Range --");
  for (int i = segment.Offset; i <= segment.Count; i++)
  {
    Console.WriteLine(segment.Array[i]);
  }
}

Hope It Helps!

What you have to do is to append the values as parameters in the iframe src (URL).

E.g. <iframe src="some_page.php?somedata=5&more=bacon"></iframe>

And then in some_page.php file you use php $_GET['somedata'] to retrieve it from the iframe URL. NB: Iframes run as a separate browser window in your file.

the first way is better, the second way cost more time on creating a new array and converting to a list

I think this is more readable given the intent:

$('someTableSelector').children( 'tr:not(:first)' ).remove();

Using children also takes care of the case where the first row contains a table by limiting the depth of the search.

If you had an TBODY element, you can do this:

$("someTableSelector > tbody:last").children().remove();

If you have THEAD or TFOOT elements you'll need to do something different.

Improving Suman.hassan95's answer by adding a link to subcategory as well. Replace the following code:

$sub_cats = get_categories( $args2 );
    if($sub_cats) {
        foreach($sub_cats as $sub_category) {
            echo  $sub_category->name ;
        }

    }

with:

$sub_cats = get_categories( $args2 );
            if($sub_cats) {
                foreach($sub_cats as $sub_category) {
                    echo  '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
                }
            }

or if you also wish a counter for each subcategory, replace with this:

$sub_cats = get_categories( $args2 );
            if($sub_cats) {
                foreach($sub_cats as $sub_category) {
                    echo  '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
                    echo apply_filters( 'woocommerce_subcategory_count_html', ' <span class="cat-count">' . $sub_category->count . '</span>', $category );
                }
            }

I was finding same but lastly i found an answer. I hope this answer help you so much.

when your array is empty then you can send empty array just like

if(!empty($result))
        {
            echo json_encode($result);
        }
        else
        {
            echo json_encode(array('data'=>''));
        }

Thank you

Convert from String to byte[]:

String s = "some text here";
byte[] b = s.getBytes(StandardCharsets.UTF_8);

Convert from byte[] to String:

byte[] b = {(byte) 99, (byte)97, (byte)116};
String s = new String(b, StandardCharsets.US_ASCII);

You should, of course, use the correct encoding name. My examples used US-ASCII and UTF-8, the two most common encodings.

basically 32bit architecture can address 4GB as you expected. There are some techniques which allows processor to address more data like AWE or PAE.

It's not possible to access camera of your development machine to be used as simulator camera. Camera functionality is not available in any iOS version and any Simulator. You will have to use device for testing camera purpose.

For completeness:

>>> def divide(x, y):
...     try:
...         result = x / y
...     except ZeroDivisionError:
...         print("division by zero!")
...     else:
...         print("result is", result)
...     finally:
...         print("executing finally clause")

Also note that you can capture the exception like this:

>>> try:
...     this_fails()
... except ZeroDivisionError as err:
...     print("Handling run-time error:", err)

...and re-raise the exception like this:

>>> try:
...     raise NameError('HiThere')
... except NameError:
...     print('An exception flew by!')
...     raise

...examples from the python tutorial.

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

An example would be nice - here's a trivial one

for %I in (*.*) do @echo %~xI

it lists only the EXTENSIONS of each file in current folder

for more useful variable combinations (also listed in previous response) from the CMD prompt execute: HELP FOR which contains this snippet

The modifiers can be combined to get compound results:

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
               environment variable for %I and expands to the
               drive letter and path of the first one found.
%~ftzaI     - expands %I to a DIR like output line

In a Form, Create a text box, with in text box properties select data tab

Default value =CurrentUser()

Current source "select table field name"

It will display current user log on name in text box / label as well as saves the user name in the table field

Here is a complete jquery plugin that solves this problem:

https://github.com/bigspotteddog/ScrollToFixed

The description of this plugin is as follows:

This plugin is used to fix elements to the top of the page, if the element would have scrolled out of view, vertically; however, it does allow the element to continue to move left or right with the horizontal scroll.

Given an option marginTop, the element will stop moving vertically upward once the vertical scroll has reached the target position; but, the element will still move horizontally as the page is scrolled left or right. Once the page has been scrolled back down past the target position, the element will be restored to its original position on the page.

This plugin has been tested in Firefox 3/4, Google Chrome 10/11, Safari 5, and Internet Explorer 8/9.

Usage for your particular case:

<script src="scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="scripts/jquery-scrolltofixed-min.js" type="text/javascript"></script>

$(document).ready(function() {
    $('#mydiv').scrollToFixed({ marginTop: 250 });
});

Write a:hover::before instead of a::before:hover: example.

\d table_name shows this information from psql, but if you want to get such information from database using SQL then have a look at Extracting META information from PostgreSQL.

I use such info in my utility to report some info from db schema to compare PostgreSQL databases in test and production environments.

           }
   

4. Using keyset() and java Iterator

        Iterator<String> keysIterator = keySet.iterator();
       while (keysIterator.hasNext()) {
           String key = keysIterator.next();
           System.out.println("Key Of map = "+ key + " , value of map = " + hashMap.get(key) );
      }

I could get away with the following solution (works with Ubuntu 14 guest VM on Windows 7 host or Ubuntu 9.10 Casper guest VM on host Windows XP x86):

1. Go to network connections -> Virtual Box Host-Only Network -> Select "Properties"
2. Check VirtualBox Bridged Networking Driver
3. Come to VirtualBox Manager, choose the network adapter as Bridged Adapter and Name to the device in Step #1.
4. Restart the VM.

Here's one I wrote:

/**
 * Format bytes as human-readable text.
 * 
 * @param bytes Number of bytes.
 * @param si True to use metric (SI) units, aka powers of 1000. False to use 
 *           binary (IEC), aka powers of 1024.
 * @param dp Number of decimal places to display.
 * 
 * @return Formatted string.
 */
function humanFileSize(bytes, si=false, dp=1) {
  const thresh = si ? 1000 : 1024;

  if (Math.abs(bytes) < thresh) {
    return bytes + ' B';
  }

  const units = si 
    ? ['kB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'] 
    : ['KiB', 'MiB', 'GiB', 'TiB', 'PiB', 'EiB', 'ZiB', 'YiB'];
  let u = -1;
  const r = 10**dp;

  do {
    bytes /= thresh;
    ++u;
  } while (Math.round(Math.abs(bytes) * r) / r >= thresh && u < units.length - 1);


  return bytes.toFixed(dp) + ' ' + units[u];
}


console.log(humanFileSize(1551859712))  // 1.4 GiB
console.log(humanFileSize(5000, true))  // 5.0 kB
console.log(humanFileSize(5000, false))  // 4.9 KiB
console.log(humanFileSize(-10000000000000000000000000000))  // -8271.8 YiB
console.log(humanFileSize(999949, true))  // 999.9 kB
console.log(humanFileSize(999950, true))  // 1.0 MB
console.log(humanFileSize(999950, true, 2))  // 999.95 kB
console.log(humanFileSize(999500, true, 0))  // 1 MB

Just change the first line as follows :

include ActionView::Helpers

that will make it works.

UPDATE: For Rails 3 use:

ActionController::Base.helpers.sanitize(str)

It's in the python docs.

import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1), 
                          datetime.time(10, 23))

returns

datetime.datetime(2011, 1, 1, 10, 23)

You can try this. This will store last item. Here need to convert obj into array. Then use array pop() function that will return last item from converted array.

var obj = { 'a' : 'apple', 'b' : 'banana', 'c' : 'carrot' };_x000D_
var last = Object.keys(obj).pop();_x000D_
console.log(last);_x000D_
console.log(obj[last]);

For people landing here from google like me and just want to build containers using multiple docker-compose files with one shared service:

Sometimes you have different projects that would share e.g. a database docker container. Only the first run should start the DB-Docker, the second should be detect that the DB is already running and skip this. To achieve such a behaviour we need the Dockers to lay in the same network and in the same project. Also the docker container name needs to be the same.

1st: Set the same network and container name in docker-compose

docker-compose in project 1:

version: '3'

services:
    service1:
        depends_on:
            - postgres
        # ...
        networks:
            - dockernet

    postgres:
        container_name: project_postgres
        image: postgres:10-alpine
        restart: always
        # ...
        networks:
            - dockernet

networks:
    dockernet:

docker-compose in project 2:

version: '3'

services:
    service2:
        depends_on:
            - postgres
        # ...
        networks:
            - dockernet

    postgres:
        container_name: project_postgres
        image: postgres:10-alpine
        restart: always
        # ...
        networks:
            - dockernet

networks:
    dockernet:

2nd: Set the same project using -p param or put both files in the same directory.

docker-compose -p {projectname} up

I'd be cautious as dismissing something as a bad idea because it is slow. If it is a part of the code that does not take much time to execute then the slowness is irrelevant. I just used the following code:

for (ic in 1:(dim(centroid)[2]))
{
cluster[[ic]]=matrix(,nrow=2,ncol=0)
}
# code to identify cluster=pindex[ip] to which to add the point
if(pdist[ip]>-1)
{
cluster[[pindex[ip]]]=cbind(cluster[[pindex[ip]]],points[,ip])
}

for a problem that ran in less than 1 second.

//use css
.blue {
    background-color:blue !important;
}
.blue th {
    color:white !important;
}

//html
<table class="table blue">.....</table>

You need to use following construction

InputStream in = getClass().getResourceAsStream("/yourFile");

Please note that you have to add this slash before your file name.

For an advance view you should check jquery-treetable

Pretty much down to personal choice. It may make sense to use an extension based on the database scheme you are storing; treat your database schema as a file format, with SQLite simply being an encoding used for that file format. So, you might use .bookmarks if it's storing bookmarks, or .index if it's being used as an index.

If you want to use a generic extension, I'd use .sqlite3 since that is most descriptive of what version of SQLite is needed to work with the database.

I think it's important to note here that onBlur() fires regardless.

This is a helpful thread but the only thing it doesn't clarify is that onBlur() will fire every single time.

onChange() will only fire when the value is changed.

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

I can't imagine that anyone else reading this is a stupid as I was but just in case... I had accidentally removed "laravel/framework": "^5.6" from my composer.json when resolving merge conflicts.

You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...

For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.

There are various approaches that you can take to accomplish deserialization of a JSON object to an enum. My favorite style is to make an inner class:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonProperty;
import org.hibernate.validator.constraints.NotEmpty;

import java.util.Arrays;
import java.util.Map;
import java.util.function.Function;
import java.util.stream.Collectors;

import static com.fasterxml.jackson.annotation.JsonFormat.Shape.OBJECT;

@JsonFormat(shape = OBJECT)
public enum FinancialAccountSubAccountType {
  MAIN("Main"),
  MAIN_DISCOUNT("Main Discount");

  private final static Map<String, FinancialAccountSubAccountType> ENUM_NAME_MAP;
  static {
    ENUM_NAME_MAP = Arrays.stream(FinancialAccountSubAccountType.values())
      .collect(Collectors.toMap(
        Enum::name,
        Function.identity()));
  }

  private final String displayName;

  FinancialAccountSubAccountType(String displayName) {
    this.displayName = displayName;
  }

  @JsonCreator
  public static FinancialAccountSubAccountType fromJson(Request request) {
    return ENUM_NAME_MAP.get(request.getCode());
  }

  @JsonProperty("name")
  public String getDisplayName() {
    return displayName;
  }

  private static class Request {
    @NotEmpty(message = "Financial account sub-account type code is required")
    private final String code;
    private final String displayName;

    @JsonCreator
    private Request(@JsonProperty("code") String code,
                    @JsonProperty("name") String displayName) {
      this.code = code;
      this.displayName = displayName;
    }

    public String getCode() {
      return code;
    }

    @JsonProperty("name")
    public String getDisplayName() {
      return displayName;
    }
  }
}

DECLARE @dayNumber INT;
SET @dayNumber = DATEPART(DW, GETDATE());

--Sunday = 1, Saturday = 7.
IF(@dayNumber = 1 OR @dayNumber = 7) 
    PRINT 'Weekend';
ELSE
    PRINT 'NOT Weekend';

This may generate wrong results, because the number produced by the weekday datepart depends on the value set by SET DATEFIRST. This sets the first day of the week. So another way is:

DECLARE @dayName VARCHAR(9);
SET @dayName = DATEName(DW, GETDATE());

IF(@dayName = 'Saturday' OR @dayName = 'Sunday') 
    PRINT 'Weekend';
ELSE
    PRINT 'NOT Weekend';

There is two way to do this

1. Command line
2. Using python program

If you are using command line use python -m compileall <argument> to compile python code to python binary code. Ex: python -m compileall -x ./*

Or, You can use this code to compile your library into byte-code.

import compileall
import os

lib_path = "your_lib_path"
build_path = "your-dest_path"

compileall.compile_dir(lib_path, force=True, legacy=True)

def moveToNewLocation(cu_path):
    for file in os.listdir(cu_path):
        if os.path.isdir(os.path.join(cu_path, file)):
            compile(os.path.join(cu_path, file))
        elif file.endswith(".pyc"):
            dest = os.path.join(build_path, cu_path ,file)
            os.makedirs(os.path.dirname(dest), exist_ok=True)
            os.rename(os.path.join(cu_path, file), dest)

moveToNewLocation(lib_path)

To understand queue method, you have to understand how jQuery does animation. If you write multiple animate method calls one after the other, jQuery creates an 'internal' queue and adds these method calls to it. Then it runs those animate calls one by one.

Consider following code.

function nonStopAnimation()
{
    //These multiple animate calls are queued to run one after
    //the other by jQuery.
    //This is the reason that nonStopAnimation method will return immeidately
    //after queuing these calls. 
    $('#box').animate({ left: '+=500'}, 4000);
    $('#box').animate({ top: '+=500'}, 4000);
    $('#box').animate({ left: '-=500'}, 4000);

    //By calling the same function at the end of last animation, we can
    //create non stop animation. 
    $('#box').animate({ top: '-=500'}, 4000 , nonStopAnimation);
}

The 'queue'/'dequeue' method gives you control over this 'animation queue'.

By default the animation queue is named 'fx'. I have created a sample page here which has various examples which will illustrate how the queue method could be used.

http://jsbin.com/zoluge/1/edit?html,output

Code for above sample page:

$(document).ready(function() {
    $('#nonStopAnimation').click(nonStopAnimation);

    $('#stopAnimationQueue').click(function() {
        //By default all animation for particular 'selector'
        //are queued in queue named 'fx'.
        //By clearning that queue, you can stop the animation.
        $('#box').queue('fx', []);
    });

    $('#addAnimation').click(function() {
        $('#box').queue(function() {
            $(this).animate({ height : '-=25'}, 2000);
            //De-queue our newly queued function so that queues
            //can keep running.
            $(this).dequeue();
        });
    });

    $('#stopAnimation').click(function() {
        $('#box').stop();
    });

    setInterval(function() {
        $('#currentQueueLength').html(
         'Current Animation Queue Length for #box ' + 
          $('#box').queue('fx').length
        );
    }, 2000);
});

function nonStopAnimation()
{
    //These multiple animate calls are queued to run one after
    //the other by jQuery.
    $('#box').animate({ left: '+=500'}, 4000);
    $('#box').animate({ top: '+=500'}, 4000);
    $('#box').animate({ left: '-=500'}, 4000);
    $('#box').animate({ top: '-=500'}, 4000, nonStopAnimation);
}

Now you may ask, why should I bother with this queue? Normally, you wont. But if you have a complicated animation sequence which you want to control, then queue/dequeue methods are your friend.

Also see this interesting conversation on jQuery group about creating a complicated animation sequence.

http://groups.google.com/group/jquery-en/browse_thread/thread/b398ad505a9b0512/f4f3e841eab5f5a2?lnk=gst

Let me know if you still have questions.

Note: The information below the horizontal line is no longer accurate with the introduction of Android 'Lollipop' 5, as GridLayout does accommodate the principle of weights since API level 21.

Quoted from the Javadoc:

Excess Space Distribution

As of API 21, GridLayout's distribution of excess space accomodates the principle of weight. In the event that no weights are specified, the previous conventions are respected and columns and rows are taken as flexible if their views specify some form of alignment within their groups. The flexibility of a view is therefore influenced by its alignment which is, in turn, typically defined by setting the gravity property of the child's layout parameters. If either a weight or alignment were defined along a given axis then the component is taken as flexible in that direction. If no weight or alignment was set, the component is instead assumed to be inflexible.

Multiple components in the same row or column group are considered to act in parallel. Such a group is flexible only if all of the components within it are flexible. Row and column groups that sit either side of a common boundary are instead considered to act in series. The composite group made of these two elements is flexible if one of its elements is flexible.

To make a column stretch, make sure all of the components inside it define a weight or a gravity. To prevent a column from stretching, ensure that one of the components in the column does not define a weight or a gravity.

When the principle of flexibility does not provide complete disambiguation, GridLayout's algorithms favour rows and columns that are closer to its right and bottom edges. To be more precise, GridLayout treats each of its layout parameters as a constraint in the a set of variables that define the grid-lines along a given axis. During layout, GridLayout solves the constraints so as to return the unique solution to those constraints for which all variables are less-than-or-equal-to the corresponding value in any other valid solution.

It's also worth noting that android.support.v7.widget.GridLayout contains the same information. Unfortunately it doesn't mention which version of the support library it was introduced with, but the commit that adds the functionality can be tracked back to July 2014. In November 2014, improvements in weight calculation and a bug was fixed.

To be safe, make sure to import the latest version of the gridlayout-v7 library.

The principle of 'weights', as you're describing it, does not exist with GridLayout. This limitation is clearly mentioned in the documentation; excerpt below. That being said, there are some possibilities to use 'gravity' for excess space distribution. I suggest you have read through the linked documentation.

Limitations

GridLayout does not provide support for the principle of weight, as defined in weight. In general, it is not therefore possible to configure a GridLayout to distribute excess space in non-trivial proportions between multiple rows or columns. Some common use-cases may nevertheless be accommodated as follows. To place equal amounts of space around a component in a cell group; use CENTER alignment (or gravity). For complete control over excess space distribution in a row or column; use a LinearLayout subview to hold the components in the associated cell group. When using either of these techniques, bear in mind that cell groups may be defined to overlap.

For an example and some practical pointers, take a look at last year's blog post introducing the GridLayout widget.

Edit: I don't think there's an xml-based approach to scaling the tiles like in the Google Play app to 'squares' or 'rectangles' twice the length of those squares. However, it is certainly possible if you build your layout programmatically. All you really need to know in order two accomplish that is the device's screen dimensions.

Below a (very!) quick 'n dirty approximation of the tiled layout in the Google Play app.

Point size = new Point();
getWindowManager().getDefaultDisplay().getSize(size);
int screenWidth = size.x;
int screenHeight = size.y;
int halfScreenWidth = (int)(screenWidth *0.5);
int quarterScreenWidth = (int)(halfScreenWidth * 0.5);

Spec row1 = GridLayout.spec(0, 2);
Spec row2 = GridLayout.spec(2);
Spec row3 = GridLayout.spec(3);
Spec row4 = GridLayout.spec(4, 2);

Spec col0 = GridLayout.spec(0);
Spec col1 = GridLayout.spec(1); 
Spec colspan2 = GridLayout.spec(0, 2);

GridLayout gridLayout = new GridLayout(this);
gridLayout.setColumnCount(2);
gridLayout.setRowCount(15);

TextView twoByTwo1 = new TextView(this);
GridLayout.LayoutParams first = new GridLayout.LayoutParams(row1, colspan2);
first.width = screenWidth;
first.height = quarterScreenWidth * 2;
twoByTwo1.setLayoutParams(first);
twoByTwo1.setGravity(Gravity.CENTER);
twoByTwo1.setBackgroundColor(Color.RED);
twoByTwo1.setText("TOP");
twoByTwo1.setTextAppearance(this, android.R.style.TextAppearance_Large);
gridLayout.addView(twoByTwo1, first);

TextView twoByOne1 = new TextView(this);
GridLayout.LayoutParams second = new GridLayout.LayoutParams(row2, col0);
second.width = halfScreenWidth;
second.height = quarterScreenWidth;
twoByOne1.setLayoutParams(second);
twoByOne1.setBackgroundColor(Color.BLUE);
twoByOne1.setText("Staff Choices");
twoByOne1.setTextAppearance(this, android.R.style.TextAppearance_Large);
gridLayout.addView(twoByOne1, second);

TextView twoByOne2 = new TextView(this);
GridLayout.LayoutParams third = new GridLayout.LayoutParams(row2, col1);
third.width = halfScreenWidth;
third.height = quarterScreenWidth;
twoByOne2.setLayoutParams(third);
twoByOne2.setBackgroundColor(Color.GREEN);
twoByOne2.setText("Games");
twoByOne2.setTextAppearance(this, android.R.style.TextAppearance_Large);
gridLayout.addView(twoByOne2, third);

TextView twoByOne3 = new TextView(this);
GridLayout.LayoutParams fourth = new GridLayout.LayoutParams(row3, col0);
fourth.width = halfScreenWidth;
fourth.height = quarterScreenWidth;
twoByOne3.setLayoutParams(fourth);
twoByOne3.setBackgroundColor(Color.YELLOW);
twoByOne3.setText("Editor's Choices");
twoByOne3.setTextAppearance(this, android.R.style.TextAppearance_Large_Inverse);
gridLayout.addView(twoByOne3, fourth);

TextView twoByOne4 = new TextView(this);
GridLayout.LayoutParams fifth = new GridLayout.LayoutParams(row3, col1);
fifth.width = halfScreenWidth;
fifth.height = quarterScreenWidth;
twoByOne4.setLayoutParams(fifth);
twoByOne4.setBackgroundColor(Color.MAGENTA);
twoByOne4.setText("Something Else");
twoByOne4.setTextAppearance(this, android.R.style.TextAppearance_Large);
gridLayout.addView(twoByOne4, fifth);

TextView twoByTwo2 = new TextView(this);
GridLayout.LayoutParams sixth = new GridLayout.LayoutParams(row4, colspan2);
sixth.width = screenWidth;
sixth.height = quarterScreenWidth * 2;
twoByTwo2.setLayoutParams(sixth);
twoByTwo2.setGravity(Gravity.CENTER);
twoByTwo2.setBackgroundColor(Color.WHITE);
twoByTwo2.setText("BOTOM");
twoByTwo2.setTextAppearance(this, android.R.style.TextAppearance_Large_Inverse);
gridLayout.addView(twoByTwo2, sixth);

The result will look somewhat like this (on my Galaxy Nexus):

ANSWER?

I'm using it for an animation for adding items to a cart - a cart icon floats to the cart area from the product "add" button, when clicked:

function addCartItem(opts) {
    for (var i=0; i<opts.qty; i++) {
        setTimeout(function() {
            console.log('ADDED ONE!');
        }, 1000*i);
    }
};

NOTE the duration is in unit times n epocs.

So starting at the the click moment, the animations start epoc (of EACH animation) is the product of each one-second-unit multiplied by the number of items.

epoc: https://en.wikipedia.org/wiki/Epoch_(reference_date)

Hope this helps!

you need /q at the end

MsiExec.exe /x {2F808931-D235-4FC7-90CD-F8A890C97B2F} /q

If you have the DLL added to your project, you can open the csproj file and see the Reference tag.

Example:

<Reference Include="System.Web.Mvc, Version=3.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" />

You can create an extension method

static class MyExtensions
{
    internal static string Repeat(this char c, int n)
    {
        return new string(c, n);
    }
}

Then you can use it like this

Console.WriteLine('\t'.Repeat(10));

Here is a simple way to do it using plain JavaScript. This is the vanilla equivalent of the jQuery script posted by pimvdb. You can test it here.

<script type='text/javascript'>
  window.onload = function(){
    document.getElementById('id_here').selectedIndex = -1;
  }
</script>

.

<select id="id_here">
  <option>aaaa</option>
  <option>bbbb</option>
</select>

Make sure the "id_here" matches in the form and in the JavaScript.

public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
    var str = controllerContext.HttpContext.Request.QueryString[bindingContext.ModelName];
    if (string.IsNullOrEmpty(str)) return null;
    var date = DateTime.ParseExact(str, "dd.MM.yyyy", null);
    return date;
}

In my case i removed

Restart=always

added

tty: true

And executed the below command to open shell (daemon process, because docker reads the compose file and stops the container once it reaches the last line of the file).

docker-compose up -d
