%~dp0 expands to current directory path of the running batch file.

To get clear understanding, let's create a batch file in a directory.

C:\script\test.bat

with contents:

@echo off
echo %~dp0

When you run it from command prompt, you will see this result:

C:\script\

I face with the same issue. I deleted the local repository and relaunched the ID. It worked fine .

Thanks to this post, I use this style to remove the red border that appears automatically with bootstrap when a required field is displayed, but user didn't have a chance to input anything already:

input.ng-pristine.ng-invalid {
    -webkit-box-shadow: none;
    -ms-box-shadow: none;
    box-shadow:none;
}

I tied this in the handler to make it work:

void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (e.Source is TabControl)
    {
      //do work when tab is changed
    }
}

The .length property only tracks properties with numeric indexes (keys). You're using strings for keys.

You can do this:

var arr_jq_TabContents = {}; // no need for an array

arr_jq_TabContents["Main"] = jq_TabContents_Main;
arr_jq_TabContents["Guide"] = jq_TabContents_Guide;
arr_jq_TabContents["Articles"] = jq_TabContents_Articles;
arr_jq_TabContents["Forum"] = jq_TabContents_Forum;

for (var key in arr_jq_TabContents) {
    console.log(arr_jq_TabContents[key]);
}

To be safe, it's a good idea in loops like that to make sure that none of the properties are unexpected results of inheritance:

for (var key in arr_jq_TabContents) {
  if (arr_jq_TabContents.hasOwnProperty(key))
    console.log(arr_jq_TabContents[key]);
}

edit — it's probably a good idea now to note that the Object.keys() function is available on modern browsers and in Node etc. That function returns the "own" keys of an object, as an array:

Object.keys(arr_jq_TabContents).forEach(function(key, index) {
  console.log(this[key]);
}, arr_jq_TabContents);

The callback function passed to .forEach() is called with each key and the key's index in the array returned by Object.keys(). It's also passed the array through which the function is iterating, but that array is not really useful to us; we need the original object. That can be accessed directly by name, but (in my opinion) it's a little nicer to pass it explicitly, which is done by passing a second argument to .forEach() — the original object — which will be bound as this inside the callback. (Just saw that this was noted in a comment below.)

Single leading underscores is a convention. there is no difference from the interpreter's point of view if whether names starts with a single underscore or not.

Double leading and trailing underscores are used for built-in methods, such as __init__, __bool__, etc.

Double leading underscores w/o trailing counterparts are a convention too, however, the class methods will be mangled by the interpreter. For variables or basic function names no difference exists.

{ name: 'book', tags: { words: ['abc','123'], lat: 33, long: 22 } }

Ans:

db.tablename.remove({'tags.words':['abc','123']})

As mentioned by tripleee in the question comments , use moreutils ifne (if input not empty).

In this case we want ifne -n which negates the test:

ls -A /tmp/empty | ifne -n command-to-run-if-empty-input

The advantage of this over many of the another answers when the output of the initial command is non-empty. ifne will start writing it to STDOUT straight away, rather than buffering the entire output then writing it later, which is important if the initial output is slowly generated or extremely long and would overflow the maximum length of a shell variable.

There are a few utils in moreutils that arguably should be in coreutils -- they're worth checking out if you spend a lot of time living in a shell.

In particular interest to the OP may be dirempty/exists tool which at the time of writing is still under consideration, and has been for some time (it could probably use a bump).

Reducing the image size before output results in something that looks sharper, in my case:

convert -density 300 a.pdf -resize 25% a.png

This answers did not help me, my php adminer showed me "No input file specified" error anyway. But I knew I changed php-version before. So, I found the reason: it is not nginx, it is php.ini doc_root parameter! I found

doc_root =

in php.ini and changed it to

;doc_root =

After this patch my adminer work good.

Tomcat can tell you in several ways. Here's the easiest:

 $ /path/to/catalina.sh version
Using CATALINA_BASE:   /usr/local/apache-tomcat-7.0.29
Using CATALINA_HOME:   /usr/local/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.29/temp
Using JRE_HOME:        /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
Using CLASSPATH:       /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.29
Server built:   Jul 3 2012 11:31:52
Server number:  7.0.29.0
OS Name:        Mac OS X
OS Version:     10.7.4
Architecture:   x86_64
JVM Version:    1.6.0_33-b03-424-11M3720
JVM Vendor:     Apple Inc.

If you don't know where catalina.sh is (or it never gets called), you can usually find it via ps:

$ ps aux | grep catalina
chris            930   0.0  3.1  2987336 258328 s000  S    Wed01PM   2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start

From the ps output, you can see both catalina.home and catalina.base. catalina.home is where the Tomcat base files are installed, and catalina.base is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.

You can also interrogate the JVM directly if you can't find it in a ps listing:

$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29

If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home and catalina.base.

I like to do it as an extension to Context so you can call it anywhere

fun Context.showKeyboard(editText: EditText) {
    val inputMethodManager: InputMethodManager =
        getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.toggleSoftInputFromWindow(
        editText.applicationWindowToken,
        InputMethodManager.SHOW_IMPLICIT, 0
    )
    editText.requestFocus()
    editText.setSelection(editText.text.length)
}

fun Context.hideKeyboard(editText: EditText) {
    val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(editText.windowToken, 0)
}

As suggested, you can use getchar() to read from the console until an end-of-line or an EOF is returned, building your own buffer. Growing buffer dynamically can occur if you are unable to set a reasonable maximum line size.

You can use also use fgets as a safe way to obtain a line as a C null-terminated string:

#include <stdio.h>

char line[1024];  /* Generously large value for most situations */

char *eof;

line[0] = '\0'; /* Ensure empty line if no input delivered */
line[sizeof(line)-1] = ~'\0';  /* Ensure no false-null at end of buffer */

eof = fgets(line, sizeof(line), stdin);

If you have exhausted the console input or if the operation failed for some reason, eof == NULL is returned and the line buffer might be unchanged (which is why setting the first char to '\0' is handy).

fgets will not overfill line[] and it will ensure that there is a null after the last-accepted character on a successful return.

If end-of-line was reached, the character preceding the terminating '\0' will be a '\n'.

If there is no terminating '\n' before the ending '\0' it may be that there is more data or that the next request will report end-of-file. You'll have to do another fgets to determine which is which. (In this regard, looping with getchar() is easier.)

In the (updated) example code above, if line[sizeof(line)-1] == '\0' after successful fgets, you know that the buffer was filled completely. If that position is proceeded by a '\n' you know you were lucky. Otherwise, there is either more data or an end-of-file up ahead in stdin. (When the buffer is not filled completely, you could still be at an end-of-file and there also might not be a '\n' at the end of the current line. Since you have to scan the string to find and/or eliminate any '\n' before the end of the string (the first '\0' in the buffer), I am inclined to prefer using getchar() in the first place.)

Do what you need to do to deal with there still being more line than the amount you read as the first chunk. The examples of dynamically-growing a buffer can be made to work with either getchar or fgets. There are some tricky edge cases to watch out for (like remembering to have the next input start storing at the position of the '\0' that ended the previous input before the buffer was extended).

Have a look at the java.lang.Character class. It has some test methods and you may find one that fits your needs.

Examples: Character.isSpaceChar(c) or !Character.isJavaLetter(c)

This is the result of ifconfig:

pi@raspberrypi:~ $ 

Cutting a bit the output, we have:

pi@raspberrypi:~ $ 
pi@raspberrypi:~ $ ifconfig eth0 | grep "inet 192" | cut -c 14-25
192.168.2.24
pi@raspberrypi:~ $ 
pi@raspberrypi:~ $ 

Now, we can go to python and do:

import os
mine = os.popen('ifconfig eth0 | grep "inet 192" | cut -c 14-25')
myip = mine.read()
print (myip)

It doesn't work because it doesn't make sense (so little sense that HTML 5 explicitly forbids it).

To fix it, decide if you want a link or a submit button and use whichever one you actually want (Hint: You don't have a form, so a submit button is nonsense).

Yes! Finally! I just tried it with Chrome, Version 66.0.3359.170 (Official Build) (64-bit) on Mac.

You can change the values in the scopes as in the first picture, or with the console as in the second picture.

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

See here for more information:

• Special Method Names - Basic Customization

I am agree with @Chad Grant

Also right if you convert to string then you can use that value as numeric as said in the question

int bar = Convert.ToInt32(new string(foo, 1)); // => gives bar=2

I tried to create a more simple and understandable example

char v = '1';
int vv = (int)char.GetNumericValue(v); 

char.GetNumericValue(v) returns as double and converts to (int)

More Advenced usage as an array

int[] values = "41234".ToArray().Select(c=> (int)char.GetNumericValue(c)).ToArray();

You can use Table::select ('name', 'surname')->where ('id', 1)->get ().

Keep in mind that when selecting for only certain fields, you will have to make another query if you end up accessing those other fields later in the request (that may be obvious, just wanted to include that caveat). Including the id field is usually a good idea so laravel knows how to write back any updates you do to the model instance.

I had the same problem and here is how it worked for me :

1) Open XAMPP control panel.

2)On the right top corner go to config > Service and Port setting and change the port (I did 81 from 80).

3)Open config in Apache just right(next) to Apache admin Option and click on that and select first one (httpd.conf) it will open in the notepad.

4) There you find port listen 80 and replace it with 81 in all place and save the file.

5) Now restart Apache and MYSql

6) Now type following in Browser : http://localhost:81/phpmyadmin/

I hope this works.

Considering that we have Set<String> stringSet we can use following:

Plain Java

List<String> strList = new ArrayList<>(stringSet);

Guava

List<String> strList = Lists.newArrayList(stringSet);

Apache Commons

List<String> strList = new ArrayList<>();
CollectionUtils.addAll(strList, stringSet);

Java 10 (Unmodifiable List)

List<String> strList = List.copyOf(stringSet);
List<String> strList = stringSet.stream().collect(Collectors.toUnmodifiableList());

Java 8 (Modifiable Lists)

import static java.util.stream.Collectors.*;
List<String> stringList1 = stringSet.stream().collect(toList());

As per the doc for the method toList()

There are no guarantees on the type, mutability, serializability, or thread-safety of the List returned; if more control over the returned List is required, use toCollection(Supplier).

So if we need a specific implementation e.g. ArrayList we can get it this way:

List<String> stringList2 = stringSet.stream().
                              collect(toCollection(ArrayList::new));

Java 8 (Unmodifiable Lists)

We can make use of Collections::unmodifiableList method and wrap the list returned in previous examples. We can also write our own custom method as:

class ImmutableCollector {
    public static <T> Collector<T, List<T>, List<T>> toImmutableList(Supplier<List<T>> supplier) {
            return Collector.of( supplier, List::add, (left, right) -> {
                        left.addAll(right);
                        return left;
                    }, Collections::unmodifiableList);
        }
}

And then use it as:

List<String> stringList3 = stringSet.stream()
             .collect(ImmutableCollector.toImmutableList(ArrayList::new)); 

Another possibility is to make use of collectingAndThen method which allows some final transformation to be done before returning result:

    List<String> stringList4 = stringSet.stream().collect(collectingAndThen(
      toCollection(ArrayList::new),Collections::unmodifiableList));

One point to note is that the method Collections::unmodifiableList returns an unmodifiable view of the specified list, as per doc. An unmodifiable view collection is a collection that is unmodifiable and is also a view onto a backing collection. Note that changes to the backing collection might still be possible, and if they occur, they are visible through the unmodifiable view. But the collector method Collectors.unmodifiableList returns truly immutable list in Java 10.

In my case, I tried most of the answers above. I solve this problem by:

• Cleaning all items in the .m2/repository folder
• Uninstall Intellij Ultimate Version
• Install Community Version

It so amazingly worked!

const request = require('request');

const headers = {
    'Accept': '*/*',
    'User-Agent': 'request',
};

const options = {
    url: "https://example.com/users/6",
    headers:  headers
};

request.get(options, (error, response, body) => {
    console.log(response.body);
});

Well with some tweaks and use of timedelta here we go:

from datetime import datetime, timedelta


def inc_date(origin_date):
    day = origin_date.day
    month = origin_date.month
    year = origin_date.year
    if origin_date.month == 12:
        delta = datetime(year + 1, 1, day) - origin_date
    else:
        delta = datetime(year, month + 1, day) - origin_date
    return origin_date + delta

final_date = inc_date(datetime.today())
print final_date.date()

One option seems to be using CSS to style the textarea

.multi-line { height:5em; width:5em; }

See this entry on SO or this one.

Amurra's accepted answer seems to imply this class is added automatically when using EditorFor but you'd have to verify this.

EDIT: Confirmed, it does. So yes, if you want to use EditorFor, using this CSS style does what you're looking for.

<textarea class="text-box multi-line" id="StoreSearchCriteria_Location" name="StoreSearchCriteria.Location">

I find that the --tree-filter option used in other answers can be very slow, especially on larger repositories with lots of commits.

Here is the method I use to completely remove a directory from the git history using the --index-filter option, which runs much quicker:

# Make a fresh clone of YOUR_REPO
git clone YOUR_REPO
cd YOUR_REPO

# Create tracking branches of all branches
for remote in `git branch -r | grep -v /HEAD`; do git checkout --track $remote ; done

# Remove DIRECTORY_NAME from all commits, then remove the refs to the old commits
# (repeat these two commands for as many directories that you want to remove)
git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch DIRECTORY_NAME/' --prune-empty --tag-name-filter cat -- --all
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

# Ensure all old refs are fully removed
rm -Rf .git/logs .git/refs/original

# Perform a garbage collection to remove commits with no refs
git gc --prune=all --aggressive

# Force push all branches to overwrite their history
# (use with caution!)
git push origin --all --force
git push origin --tags --force

You can check the size of the repository before and after the gc with:

git count-objects -vH

Code

import java.util.Scanner;

public class LoginMain {

public static void main(String[] args) {

    String Username;
    String Password;

    Password = "123";
    Username = "wisdom";

    Scanner input1 = new Scanner(System.in);
    System.out.println("Enter Username : ");
    String username = input1.next();

    Scanner input2 = new Scanner(System.in);
    System.out.println("Enter Password : ");
    String password = input2.next();

    if (username.equals(Username) && password.equals(Password)) {

        System.out.println("Access Granted! Welcome!");
    }

    else if (username.equals(Username)) {
        System.out.println("Invalid Password!");
    } else if (password.equals(Password)) {
        System.out.println("Invalid Username!");
    } else {
        System.out.println("Invalid Username & Password!");
    }

}

}

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

Something like this (I'm not a VB programmer)

Public Class MyParameters
    public Name As String
    public Number As Integer
End Class



newThread as thread = new Thread( AddressOf DoWork)
Dim parameters As New MyParameters
parameters.Name = "Arne"
newThread.Start(parameters);

public shared sub DoWork(byval data as object)
{
    dim parameters = CType(data, Parameters)

}

Comparator is a functional interface, and Integer::max complies with that interface (after autoboxing/unboxing is taken into consideration). It takes two int values and returns an int - just as you'd expect a Comparator<Integer> to (again, squinting to ignore the Integer/int difference).

However, I wouldn't expect it to do the right thing, given that Integer.max doesn't comply with the semantics of Comparator.compare. And indeed it doesn't really work in general. For example, make one small change:

for (int i = 1; i <= 20; i++)
    list.add(-i);

... and now the max value is -20 and the min value is -1.

Instead, both calls should use Integer::compare:

System.out.println(list.stream().max(Integer::compare).get());
System.out.println(list.stream().min(Integer::compare).get());

var firstName = "Ada";
var lastLetterOfFirstName = firstName[firstName.length - 1];

I have tried setting the heap size upto 2200M on 32bit Linux machine and JVM worked fine. The JVM didnt start when I set it to 2300M.

Welcome to every C/C++ programmer's bestest friend: Undefined Behavior.

There is a lot that is not specified by the language standard, for a variety of reasons. This is one of them.

In general, whenever you encounter undefined behavior, anything might happen. The application may crash, it may freeze, it may eject your CD-ROM drive or make demons come out of your nose. It may format your harddrive or email all your porn to your grandmother.

It may even, if you are really unlucky, appear to work correctly.

The language simply says what should happen if you access the elements within the bounds of an array. It is left undefined what happens if you go out of bounds. It might seem to work today, on your compiler, but it is not legal C or C++, and there is no guarantee that it'll still work the next time you run the program. Or that it hasn't overwritten essential data even now, and you just haven't encountered the problems, that it is going to cause — yet.

As for why there is no bounds checking, there are a couple aspects to the answer:

• An array is a leftover from C. C arrays are about as primitive as you can get. Just a sequence of elements with contiguous addresses. There is no bounds checking because it is simply exposing raw memory. Implementing a robust bounds-checking mechanism would have been almost impossible in C.
• In C++, bounds-checking is possible on class types. But an array is still the plain old C-compatible one. It is not a class. Further, C++ is also built on another rule which makes bounds-checking non-ideal. The C++ guiding principle is "you don't pay for what you don't use". If your code is correct, you don't need bounds-checking, and you shouldn't be forced to pay for the overhead of runtime bounds-checking.
• So C++ offers the std::vector class template, which allows both. operator[] is designed to be efficient. The language standard does not require that it performs bounds checking (although it does not forbid it either). A vector also has the at() member function which is guaranteed to perform bounds-checking. So in C++, you get the best of both worlds if you use a vector. You get array-like performance without bounds-checking, and you get the ability to use bounds-checked access when you want it.

use the HorizontalContentAlignment property.

Sample

<Label HorizontalContentAlignment="Center"/>

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

This should do the trick

'g' in df.index

JavaScript works with the number of milliseconds since the epoch whereas most other languages work with the seconds. You could work with milliseconds but as soon as you pass a value to say PHP, the PHP native functions will probably fail. So to be sure I always use the seconds, not milliseconds.

This will give you a Unix timestamp (in seconds):

var unix = Math.round(+new Date()/1000);

This will give you the milliseconds since the epoch (not Unix timestamp):

var milliseconds = new Date().getTime();

imports are used to import supporting modules like FormsModule, RouterModule, CommonModule, or any other custom-made feature module.

declarations are used to declare components, directives, pipes that belong to the current module. Everyone inside declarations knows each other. For example, if we have a component, say UsernameComponent, which displays a list of the usernames and we also have a pipe, say toupperPipe, which transforms a string to an uppercase letter string. Now If we want to show usernames in uppercase letters in our UsernameComponent then we can use the toupperPipe which we had created before but the question is how UsernameComponent knows that the toupperPipe exists and how it can access and use that. Here come the declarations, we can declare UsernameComponent and toupperPipe.

Providers are used for injecting the services required by components, directives, pipes in the module.

why @Marco Berrocl get a negative feedback and his answer is totally right what about using a library to make some animation so i need to call the class in hover to element not copy the code from the library and this will make me slow.

so i think hover not the answer and he should use jquery or javascript in many cases

Java solution

• The "-" is used to left indent

• The "15" makes the String's minimum length it takes up be 15

• The "s" (which is a few characters after %) will be substituted by our String
• The 0 pads our integer with 0s on the left
• The 3 makes our integer be a minimum length of 3

How about iconv:

http://php.net/manual/en/function.iconv.php

Haven't used it inside PHP itself but its always performed well for me on the command line. You can get it to substitute invalid characters.

A Stacked bar chart should suffice:

Setup data as follows

Fred    1/01/1981   1/06/1985    1612

Jim     1/03/1999   1/01/2000    306  

1. Plot Start and Duration as a stacked bar chart
2. Set the X-Axis minimum to the desired start date
3. Set the Fill Colour of thestart range to no fill
4. Set the Fill of individual bars to suit

A function using the symmetric difference set operator, as mentioned in other answers, which preserves the origins of the values:

def diff_dicts(a, b, missing=KeyError):
    """
    Find keys and values which differ from `a` to `b` as a dict.

    If a value differs from `a` to `b` then the value in the returned dict will
    be: `(a_value, b_value)`. If either is missing then the token from 
    `missing` will be used instead.

    :param a: The from dict
    :param b: The to dict
    :param missing: A token used to indicate the dict did not include this key
    :return: A dict of keys to tuples with the matching value from a and b
    """
    return {
        key: (a.get(key, missing), b.get(key, missing))
        for key in dict(
            set(a.items()) ^ set(b.items())
        ).keys()
    }

Example

print(diff_dicts({'a': 1, 'b': 1}, {'b': 2, 'c': 2}))

# {'c': (<class 'KeyError'>, 2), 'a': (1, <class 'KeyError'>), 'b': (1, 2)}

How this works

We use the symmetric difference set operator on the tuples generated from taking items. This generates a set of distinct (key, value) tuples from the two dicts.

We then make a new dict from that to collapse the keys together and iterate over these. These are the only keys that have changed from one dict to the next.

We then compose a new dict using these keys with a tuple of the values from each dict substituting in our missing token when the key isn't present.

my_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456']

for item in my_list:
    if (item.find('abc')) != -1:
        print ('Found at ', item)

My guess is that you're trying to squeeze a number greater than 99999.99 into your decimal fields. Changing it to (8,3) isn't going to do anything if it's greater than 99999.999 - you need to increase the number of digits before the decimal. You can do this by increasing the precision (which is the total number of digits before and after the decimal). You can leave the scale the same unless you need to alter how many decimal places to store. Try decimal(9,2) or decimal(10,2) or whatever.

You can test this by commenting out the insert #temp and see what numbers the select statement is giving you and see if they are bigger than your column can handle.

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

Can't you just separate them by a semicolon?

Delete from messages where messageid = '1';
Delete from usersmessages where messageid = '1'

OR

Just use INNER JOIN as below

DELETE messages , usersmessages  FROM messages  INNER JOIN usersmessages  
WHERE messages.messageid= usersmessages.messageid and messages.messageid = '1'

The setting was disabled in Jupyter 5.X and higher by adding below code

pylab = Unicode('disabled', config=True,
    help=_("""
    DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
    """)
)

@observe('pylab')
def _update_pylab(self, change):
    """when --pylab is specified, display a warning and exit"""
    if change['new'] != 'warn':
        backend = ' %s' % change['new']
    else:
        backend = ''
    self.log.error(_("Support for specifying --pylab on the command line has been removed."))
    self.log.error(
        _("Please use `%pylab{0}` or `%matplotlib{0}` in the notebook itself.").format(backend)
    )
    self.exit(1)

And in previous versions it has majorly been a warning. But this not a big issue because Jupyter uses concepts of kernels and you can find kernel for your project by running below command

$ jupyter kernelspec list
Available kernels:
  python3    /Users/tarunlalwani/Documents/Projects/SO/notebookinline/bin/../share/jupyter/kernels/python3

This gives me the path to the kernel folder. Now if I open the /Users/tarunlalwani/Documents/Projects/SO/notebookinline/bin/../share/jupyter/kernels/python3/kernel.json file, I see something like below

{
 "argv": [
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}",
 ],
 "display_name": "Python 3",
 "language": "python"
}

So you can see what command is executed to launch the kernel. So if you run the below command

$ python -m ipykernel_launcher --help
IPython: an enhanced interactive Python shell.

Subcommands
-----------

Subcommands are launched as `ipython-kernel cmd [args]`. For information on
using subcommand 'cmd', do: `ipython-kernel cmd -h`.

install
    Install the IPython kernel

Options
-------

Arguments that take values are actually convenience aliases to full
Configurables, whose aliases are listed on the help line. For more information
on full configurables, see '--help-all'.

....
--pylab=<CaselessStrEnum> (InteractiveShellApp.pylab)
    Default: None
    Choices: ['auto', 'agg', 'gtk', 'gtk3', 'inline', 'ipympl', 'nbagg', 'notebook', 'osx', 'pdf', 'ps', 'qt', 'qt4', 'qt5', 'svg', 'tk', 'widget', 'wx']
    Pre-load matplotlib and numpy for interactive use, selecting a particular
    matplotlib backend and loop integration.
--matplotlib=<CaselessStrEnum> (InteractiveShellApp.matplotlib)
    Default: None
    Choices: ['auto', 'agg', 'gtk', 'gtk3', 'inline', 'ipympl', 'nbagg', 'notebook', 'osx', 'pdf', 'ps', 'qt', 'qt4', 'qt5', 'svg', 'tk', 'widget', 'wx']
    Configure matplotlib for interactive use with the default matplotlib
    backend.
...    
To see all available configurables, use `--help-all`

So now if we update our kernel.json file to

{
 "argv": [
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}",
  "--pylab",
  "inline"
 ],
 "display_name": "Python 3",
 "language": "python"
}

And if I run jupyter notebook the graphs are automatically inline

Note the below approach also still works, where you create a file on below path

~/.ipython/profile_default/ipython_kernel_config.py

c = get_config()
c.IPKernelApp.matplotlib = 'inline'

But the disadvantage of this approach is that this is a global impact on every environment using python. You can consider that as an advantage also if you want to have a common behaviour across environments with a single change.

So choose which approach you would like to use based on your requirement

In CodeIgniter 3.16 in using htaccess to

remove index.php file

& also

redirect HTTP to HTTPS

Follow are the codes:

• go to application\config\config.php file

Make changes

$config['index_page'] = 'index.php';

To

$config['index_page'] = '';

• Now, Open the .htaccess file, and update the codes below

RewriteEngine on
RewriteBase /

## Redirect SSL
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R,L]

## Remove fron url index.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond $1 !^/(index\.php|assets/|humans\.txt)
RewriteRule ^(.*)$ index.php/$1 [L] 

@JonnyBuchanan's answer works perfectly, but for only array state variable. In case the state variable is just a single dictionary, follow this:

inputChange = input => e => {
    this.setState({
        item: update(this.state.item, {[input]: {$set: e.target.value}})
    })
}

You can replace [input] by the field name of your dictionary and e.target.value by its value. This code performs the update job on input change event of my form.

Old Question, but for angular 6, this needs to be done when you are using HttpClient I am exposing token data publicly here but it would be good if accessed via read-only properties.

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable, of } from 'rxjs';
import { delay, tap } from 'rxjs/operators';
import { Router } from '@angular/router';


@Injectable()
export class AuthService {
    isLoggedIn: boolean = false;
    url = "token";

    tokenData = {};
    username = "";
    AccessToken = "";

    constructor(private http: HttpClient, private router: Router) { }

    login(username: string, password: string): Observable<object> {
        let model = "username=" + username + "&password=" + password + "&grant_type=" + "password";

        return this.http.post(this.url, model).pipe(
            tap(
                data => {
                    console.log('Log In succesful')
                    //console.log(response);
                    this.isLoggedIn = true;
                    this.tokenData = data;
                    this.username = data["username"];
                    this.AccessToken = data["access_token"];
                    console.log(this.tokenData);
                    return true;

                },
                error => {
                    console.log(error);
                    return false;

                }
            )
        );
    }
}

Just for reference, a for loop can be used after getting the first row to get the rest of the file:

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    row1 = next(reader)  # gets the first line
    for row in reader:
        print(row)       # prints rows 2 and onward

sudo apt-get install php5-cli php5-dev make

sudo apt-get install libsqlite3-0 libsqlite3-dev

sudo apt-get install php5-sqlite3

sudo apt-get remove php5-sqlite3

cd ~

wget http://pecl.php.net/get/sqlite3-0.6.tgz

tar -zxf sqlite3-0.6.tgz

cd sqlite3-0.6/

sudo phpize

sudo ./configure

That worked for me.

if(!activity.isFinishing() && !activity.isDestroyed())

From the official docs:

Activity#isFinishing()

Check to see whether this activity is in the process of finishing, either because you called finish() on it or someone else has requested that it finished. This is often used in onPause() to determine whether the activity is simply pausing or completely finishing.

Activity#isDestroyed()

Returns true if the final onDestroy() call has been made on the Activity, so this instance is now dead.

or perhaps:

...
for files in glob('path/*.mp3'):

for files in glob('path/*.flac'):

For Django 1.6.6:

BASE_DIR = os.path.dirname(os.path.dirname(__file__))
TEMPLATE_DIRS = os.path.join(BASE_DIR, 'templates')

Also static and media for debug and production mode:

STATIC_URL = '/static/'
MEDIA_URL = '/media/'
if DEBUG:
    STATIC_ROOT = os.path.join(BASE_DIR, 'static')
    MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
else:
    STATIC_ROOT = %REAL_PATH_TO_PRODUCTION_STATIC_FOLDER%
    MEDIA_ROOT = %REAL_PATH_TO_PRODUCTION_MEDIA_FOLDER%

Into urls.py you must add:

from django.conf.urls import patterns, include, url
from django.contrib import admin
from django.conf.urls.static import static
from django.conf import settings

from news.views import Index

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    ...
    )

urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

In Django 1.8 you can set template paths, backend and other parameters for templates in one dictionary (settings.py):

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            path.join(BASE_DIR, 'templates')
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

Official docs.

Besides the wildcards, the difference between = AND LIKE will depend on both the kind of SQL server and on the column type.

Take this example:

CREATE TABLE testtable (
  varchar_name VARCHAR(10),
  char_name CHAR(10),
  val INTEGER
);

INSERT INTO testtable(varchar_name, char_name, val)
    VALUES ('A', 'A', 10), ('B', 'B', 20);

SELECT 'VarChar Eq Without Space', val FROM testtable WHERE varchar_name='A'
UNION ALL
SELECT 'VarChar Eq With Space', val FROM testtable WHERE varchar_name='A '
UNION ALL
SELECT 'VarChar Like Without Space', val FROM testtable WHERE varchar_name LIKE 'A'
UNION ALL
SELECT 'VarChar Like Space', val FROM testtable WHERE varchar_name LIKE 'A '
UNION ALL
SELECT 'Char Eq Without Space', val FROM testtable WHERE char_name='A'
UNION ALL
SELECT 'Char Eq With Space', val FROM testtable WHERE char_name='A '
UNION ALL
SELECT 'Char Like Without Space', val FROM testtable WHERE char_name LIKE 'A'
UNION ALL
SELECT 'Char Like With Space', val FROM testtable WHERE char_name LIKE 'A '

• Using MS SQL Server 2012, the trailing spaces will be ignored in the comparison, except with LIKE when the column type is VARCHAR.

• Using MySQL 5.5, the trailing spaces will be ignored for =, but not for LIKE, both with CHAR and VARCHAR.

• Using PostgreSQL 9.1, spaces are significant with both = and LIKE using VARCHAR, but not with CHAR (see documentation).

  The behaviour with LIKE also differs with CHAR.

  Using the same data as above, using an explicit CAST on the column name also makes a difference:

  SELECT 'CAST none', val FROM testtable WHERE char_name LIKE 'A'
  UNION ALL
  SELECT 'CAST both', val FROM testtable WHERE
      CAST(char_name AS CHAR) LIKE CAST('A' AS CHAR)
  UNION ALL
  SELECT 'CAST col', val FROM testtable WHERE CAST(char_name AS CHAR) LIKE 'A'
  UNION ALL
  SELECT 'CAST value', val FROM testtable WHERE char_name LIKE CAST('A' AS CHAR)
  

  This only returns rows for "CAST both" and "CAST col".

I experienced this error and did all the suggestions from you guys here but none had any effect for my error.

I caught the culprit: if you are using *.ini file for your system, you might want to check what server name was input there and make sure it is the same as the one in your web.config connection string.

Use look behinds in preg_replace to remove anything before //.

preg_replace('(^[a-z]+:\/\/)', '', $url); 

This will only replace if found in the beginning of the string, and will ignore if found later

In jquery set focus

$(function() {
  $("#txtBox1").focus();
});

or in Javascript you can do

window.onload = function() {
  document.getElementById("txtBox1").focus();
};

Have you tried binding the list to the datagridview directly? If not, try that first because it will save you lots of pain. If you have tried it already, please tell us what went wrong so we can better advise you. Data binding gives you different behaviour depending on what interfaces your data object implements. For example, if your data object only implements IEnumerable (e.g. List), you will get very basic one-way binding, but if it implements IBindingList as well (e.g. BindingList, DataView), then you get two-way binding.

For completeness, write_csv() from the readr package is faster and never writes row names

# install.packages('readr', dependencies = TRUE)
library(readr)
write_csv(t, "t.csv")

If you need to write big data out, use fwrite() from the data.table package. It's much faster than both write.csv and write_csv

# install.packages('data.table')
library(data.table)
fwrite(t, "t.csv")

Below is a benchmark that Edouard published on his site

Flayway don't recognize the direct environment variables into the application.properties (Spring-Boot V2.1). e.g

spring.datasource.url=jdbc:mysql://${DB_HOSTNAME}:${DB_PORT}/${DB_DATABASE}
spring.datasource.username=${DB_USER}
spring.datasource.password=${DB_PASS}

To solve this issue I did this environment variables, usually I create the file .env:

SPRING_DATASOURCE_URL=jdbc:mysql://127.0.0.1:3306/place
SPRING_DATASOURCE_USERNAME=root
SPRING_DATASOURCE_PASSWORD=root

And export the variables to my environment:

export $(cat .env | xargs)

And finally just run the command

mvn spring-boot:run

Or run your jar file

java -jar target/your-file.jar

There another approach here: https://docs.spring.io/spring-boot/docs/2.1.0.BUILD-SNAPSHOT/maven-plugin/examples/run-env-variables.html

All of these answers are simple and good. However, I always like to add an interactive mode to these scripts so that I can find false positives.

if [[ -n $inInteractiveMode ]]
then
  echo -e -n "$oldFileName => $newFileName\nDo you want to do this change? [Y/n]: "
  read run

  [[ -z $run || "$run" == "y" || "$run" == "Y" ]] && mv "$oldFileName" "$newFileName"
fi

Or make interactive mode the default and add a force flag (-f | --force) for automated scripts or if you're feeling daring. And this doesn't slow you down too much: the default response is "yes, I do want to rename" so you can just hit the enter key at each prompt (because of the ``-z $run\ test.

 var cors = new EnableCorsAttribute("*","*","*");

In my case, IIS was fine but.. uh.. all the files in the folder except web.config had been deleted (a manual deployment half-done on a test site).

C++ is a general-purpose programming language. It is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell Labs as an enhancement to the C programming language and originally named "C with Classes". It was renamed to C++ in 1983.

C++ is widely used in the software industry. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. Several groups provide both free and proprietary C++ compiler software, including the GNU Project, Microsoft, Intel, Borland and others.

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. MSVC is proprietary software; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms. It features tools for developing and debugging C++ code, especially code written for Windows API, DirectX and .NET Framework.

So the main difference between them is that they are different things. The former is a programming language, while the latter is a commercial integrated development environment (IDE).

Use newDirName = os.path.abspath(dir) to create a full directory path name for the subdirectory and then list its contents as you have done with the parent (i.e. newDirList = os.listDir(newDirName))

You can create a separate method of your code snippet and call it recursively through the subdirectory structure. The first parameter is the directory pathname. This will change for each subdirectory.

This answer is based on the 3.1.1 version documentation of the Python Library. There is a good model example of this in action on page 228 of the Python 3.1.1 Library Reference (Chapter 10 - File and Directory Access). Good Luck!

Use the menu selection Navigate -> Test, or Ctrl+Shift+T (Shift+?+T on Mac). This will go to the existing test class, or offer to generate it for you through a little wizard.

Assuming all of these columns are int, then the first thing to sort out is converting one or more of them to a better data type - int division performs truncation, so anything less than 100% would give you a result of 0:

select (100.0 * (SPGI09_EARLY_OVER_T – SPGI09_OVER_WK_EARLY_ADJUST_T)) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)
from 
CSPGI09_OVERSHIPMENT 

Here, I've mutiplied one of the numbers by 100.0 which will force the result of the calculation to be done with floats rather than ints. By choosing 100, I'm also getting it ready to be treated as a %.

I was also a little confused by your bracketing - I think I've got it correct - but you had brackets around single values, and then in other places you had a mix of operators (- and /) at the same level, and so were relying on the precedence rules to define which operator applied first.

To schedule the update to be automatic you should:

• Go to Control Panel » Administrative Tools » Scheduled Tasks
• Create the (basic) task
• Go to Schedule » Advanced
• Check the box for "Repeat Task" every 10 minutes with a duration of, e.g. 24 hours or Indefinitely
• Leave End Date unchecked

If you cannot find the Schedule settings, look under: Properties, Edit, Triggers.

i think you are not pausing the program before it ended so the output you are putting after getting the inpus is not seeing on the screen right?

do:

getchar();

before the end of the program

The following query will help to find out free space of tablespaces in MB:

Even if you have unchecked the "Display intranet sites in Compatibility View" option, and have the X-UA-Compatible in your response headers, there is another reason why your browser might default to "Compatibility View" anyways - your Group Policy. Look at your console for the following message:

HTML1203: xxx.xxx has been configured to run in Compatibility View through Group Policy.

Where xxx.xxx is the domain for your site (i.e. test.com). If you see this then the group policy for your domain is set so that any site ending in test.com will automatically render in Compatibility mode regardless of doctype, headers, etc.

Selector name{
font-weight:bold;
}

Suppose you want to make bold for p element

p{
font-weight:bold;
}

You can use other alternative value instead of bold like

p{
 font-weight:bolder;
 font-weight:600;
}

Unlike other languages you may be used to, everything in C++ has to be declared before it can be used. The compiler will read your source file from top to bottom, so when it gets to the call to swapCase, it doesn't know what it is so you get an error. You can declare your function ahead of main with a line like this:

void swapCase(char *name);

or you can simply move the entirety of that function ahead of main in the file. Don't worry about having the seemingly most important function (main) at the bottom of the file. It is very common in C or C++ to do that.

What is the difference between creating cookies on the server and on the client?

What you are referring to are the 2 ways in which cookies can be directed to be set on the client, which are:

• By server
• By client ( browser in most cases )

By server: The Set-cookie response header from the server directs the client to set a cookie on that particular domain. The implementation to actually create and store the cookie lies in the browser. For subsequent requests to the same domain, the browser automatically sets the Cookie request header for each request, thereby letting the server have some state to an otherwise stateless HTTP protocol. The Domain and Path cookie attributes are used by the browser to determine which cookies are to be sent to a server. The server only receives name=value pairs, and nothing more.

By Client: One can create a cookie on the browser using document.cookie = cookiename=cookievalue. However, if the server does not intend to respond to any random cookie a user creates, then such a cookie serves no purpose.

Are these called server side cookies and client side cookies?

Cookies always belong to the client. There is no such thing as server side cookie.

Is there a way to create cookies that can only be read on the server or on the client?

Since reading cookie values are upto the server and client, it depends if either one needs to read the cookie at all. On the client side, by setting the HttpOnly attribute of the cookie, it is possible to prevent scripts ( mostly Javscript ) from reading your cookies , thereby acting as a defence mechanism against Cookie theft through XSS, but sends the cookie to the intended server only.

Therefore, in most of the cases since cookies are used to bring 'state' ( memory of past user events ), creating cookies on client side does not add much value, unless one is aware of the cookies the server uses / responds to.

$("label[for='"+$(this).attr("id")+"']");

This should allow you to select labels for all the fields in a loop as well. All you need to ensure is your labels should say for='FIELD' where FIELD is the id of the field for which this label is being defined.

I have some experience at recovering from eclipse when it becomes unstartable for whatever reason, could these blog entries help you?

link (archived)

also search for "cannot start eclipse" (I am a new user, I can only post a single hyperlink, so I have to just ask that you search for the second :( sorry)

perhaps those allow you to recover your workspace as well, I hope it helps.

This gives me the same error as trying to split the list up and zip it. ValueError: dictionary update sequence element #0 has length 1916; 2 is required

THAT is your actual question.

The answer is that the elements of your list are not what you think they are. If you type myList[0] you will find that the first element of your list is not a two-tuple, e.g. ('A', 1), but rather a 1916-length iterable.

Once you actually have a list in the form you stated in your original question (myList = [('A',1),('B',2),...]), all you need to do is dict(myList).

If you want to get the inputs of that type with that class use:

$("input.myClass[type=checkbox]")

the [] selector syntax allows you to check against any of the elements attributes. Check out the spec for more details

The solutions here didn't work for me as I'm styling react components.

What worked though for the sidebar was

Hope this helps someone.

Adding my answer, because it elaborates the idea that you can SELECT multiple columns from the table from which you subquery.

Here I needed the the most recently cast cote and it's associated information.

I first tried simply to SELECT the max(votedate) along with vote, itemid, userid etc., but while the query would return the max votedate, it would also return the a random row for the other information. Hard to see among a bunch of 1s and 0s.

This worked well:

$query = "  
    SELECT t1.itemid, t1.itemtext, t2.vote, t2.votedate, t2.userid 
    FROM
        (
        SELECT itemid, itemtext FROM oc_item ) t1
    LEFT JOIN 
        (
        SELECT vote, votedate, itemid,userid FROM oc_votes
        WHERE votedate IN 
        (select max(votedate) FROM oc_votes group by itemid)
        AND userid=:userid) t2
    ON (t1.itemid = t2.itemid)
    order by itemid ASC
";

The subquery in the WHERE clause WHERE votedate IN (select max(votedate) FROM oc_votes group by itemid) returns one record - the record with the max vote date.

I have the same problem but in reverse, and the following solution. I want to put html from a div in a textarea (so I can edit some reactions on my website; I want to have the textarea in the same location.)

To put the content of this div in a textarea I use:

var content = $('#msg500').text();_x000D_
$('#msg500').wrapInner('<textarea>' + content + '</textarea>');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="msg500">here some <strong>html</strong> <i>tags</i>.</div>

You'll find that instances of list do not provide a __hash__ --rather, that attribute of each list is actually None (try print [].__hash__). Thus, list is unhashable.

The reason your code works with list and not set is because set constructs a single set of items without duplicates, whereas a list can contain arbitrary data.

Use ls() function to see what R objects are occupying space. use rm("objectName") to clear the objects from R memory that is no longer required. See this too.

Use this:

SELECT * 
FROM tablename 
ORDER BY priority desc, FIELD(name, "core")

The first is the most concise, I would go with that. The first two are the same, but the first is just that little bit shorter, so you'll save on bytes. The third is plain wrong, because that condition will always evaluate true because the object will never be null or falsy for that matter.

This finally became a part of support v4 library, NestedScrollView. So, no longer local hacks is needed for most of cases I'd guess.

Adding context to hopefully help provide a bit of additional clarity on this subject. To a BaSH newbie, it's sense of true/false statements is rather odd. Take the following simple examples and their results.

This statement will return "true":

foo=" "; if [ "$foo" ]; then echo "true"; else echo "false"; fi

But this will return "false":

foo=" "; if [ $foo ]; then echo "true"; else echo "false"; fi

Do you see why? The first example has a quoted "" string. This causes BaSH to treat it literally. So, in a literal sense, a space is not null. While in a non-literal sense (the 2nd example above), a space is viewed by BaSH (as a value in $foo) as 'nothing' and therefore it equates to null (interpreted here as 'false').

These statements will all return a text string of "false":

foo=; if [ $foo ]; then echo "true"; else echo "false"; fi
foo=; if [ "$foo" ]; then echo "true"; else echo "false"; fi
foo=""; if [ $foo ]; then echo "true"; else echo "false"; fi
foo=""; if [ "$foo" ]; then echo "true"; else echo "false"; fi

Interestingly, this type of conditional will always return true:

These statements will all return a result of "true":

foo=""; if [ foo ]; then echo "true"; else echo "false"; fi

Notice the difference; the $ symbol has been omitted from preceding the variable name in the conditional. It doesn't matter what word you insert between the brackets. BaSH will always see this statement as true, even if you use a word that has never been associated with a variable in the same shell before.

if [ sooperduper ]; then echo "true"; else echo "false"; fi

Likewise, defining it as an undeclared variable ensures it will always return false:

if [ $sooperduper ]; then echo "true"; else echo "false"; fi

As to BaSH it's the same as writing:

sooperduper="";if [ $sooperduper ]; then echo "true"; else echo "false"; fi

One more tip....

Brackets vs No Brackets

Making matters more confusing, these variations on the IF/THEN conditional both work, but return opposite results.

These return false:

if [ $foo ]; then echo "true"; else echo "false"; fi
if [ ! foo ]; then echo "true"; else echo "false"; fi

However, these will return a result of true:

if $foo; then echo "true"; else echo "false"; fi
if [ foo ]; then echo "true"; else echo "false"; fi
if [ ! $foo ]; then echo "true"; else echo "false"; fi

And, of course this returns a syntax error (along with a result of 'false'):

if foo; then echo "true"; else echo "false"; fi

Confused yet? It can be quite challenging to keep it straight in your head in the beginning, especially if you're used to other, higher level programming languages.

you can use this as well

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

var queryValue = getParameterByName('test_user_bLzgB');

The tibble package now has a dedicated function that converts row names to an explicit variable.

Try this:

var date = new Date();
console.log(date instanceof Date && !isNaN(date.valueOf()));

This should return true.

UPDATED: Added isNaN check to handle the case commented by Julian H. Lam

Another alternative is to use a markdown editor like StackEdit. It converts html (or text) into markdown in a WYSIWYG editor. You can create indents, titles, lists in the editor, and it will show you the corresponding text in markdown format. You can then save, publish, share, or download the file. You can access it on their website - no downloads required!

You can simply use __qualname__ which stands for qualified name of a function or class

Example:

>>> class C:
...     class D:
...         def meth(self):
...             pass
...
>>> C.__qualname__
'C'
>>> C.D.__qualname__
'C.D'
>>> C.D.meth.__qualname__
'C.D.meth'

Steps: 1. Open a command prompt with administrator's rights.

Steps: 2. Run the command: setx /M PATH "path\to;%PATH%"

[Note: Be sure to alter the command so that path\to reflects the folder path from your root.]

Example : setx /M PATH "C:\Program Files;%PATH%"

public static void main(String[] args) {

I Solved it. I just had to add the path of android studio's platform-tools after removing my earlier eclipse's path. I don't know, maybe some conflict in the command.

After finding this StackOverflow question/answer

Complex type is getting null in a ApiController parameter

the [FromBody] attribute on the controller method needs to be [FromUri] since a GET does not have a body. After this change the "filter" complex object is passed correctly.

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

Faced the same error. In my case , what i did wrong was that i injected the service(named DataService in my case) inside the constructor within the Component but I simply forgot to import it within the component.

 constructor(private dataService:DataService ) {
    console.log("constructor called");
  }

I missed the below import code.

import { DataService } from '../../services/data.service';

I don't know about JSON.NET, but it works fine with JavaScriptSerializer from System.Web.Extensions.dll (.NET 3.5 SP1):

I performed tests on Eclipse vs Netbeans 8.0.2, both with Java version 1.8; I used System.nanoTime() for measurements.

Eclipse:

I got the same time on both cases - around 1.564 seconds.

Netbeans:

• Using "#": 1.536 seconds
• Using "B": 44.164 seconds

So, it looks like Netbeans has bad performance on print to console.

After more research I realized that the problem is line-wrapping of the max buffer of Netbeans (it's not restricted to System.out.println command), demonstrated by this code:

for (int i = 0; i < 1000; i++) {
    long t1 = System.nanoTime();
    System.out.print("BBB......BBB"); \\<-contain 1000 "B"
    long t2 = System.nanoTime();
    System.out.println(t2-t1);
    System.out.println("");
}

The time results are less then 1 millisecond every iteration except every fifth iteration, when the time result is around 225 millisecond. Something like (in nanoseconds):

BBB...31744
BBB...31744
BBB...31744
BBB...31744
BBB...226365807

Summary:

1. Eclipse works perfectly with "B"
2. Netbeans has a line-wrapping problem that can be solved (because the problem does not occur in eclipse)(without adding space after B ("B ")).

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

Actually ngAfterViewInit() will initiate only once when the component initiate.

If you really want a event triggers after the HTML element renter on the screen then you can use ngAfterViewChecked()

Anonymous ftp logins are usually the username 'anonymous' with the user's email address as the password. Some servers parse the password to ensure it looks like an email address.

For temporary internal files their are 2 options

1.

File file; 
file = File.createTempFile(filename, null, this.getCacheDir());

2.

File file
file = new File(this.getCacheDir(), filename);

Both options adds files in the applications cache directory and thus can be cleared to make space as required but option 1 will add a random number on the end of the filename to keep files unique. It will also add a file extension which is .tmp by default, but it can be set to anything via the use of the 2nd parameter. The use of the random number means despite specifying a filename it doesn't stay the same as the number is added along with the suffix/file extension (.tmp by default) e.g you specify your filename as internal_file and comes out as internal_file1456345.tmp. Whereas you can specify the extension you can't specify the number that is added. You can however find the filename it generates via file.getName();, but you would need to store it somewhere so you can use it whenever you wanted for example to delete or read the file. Therefore for this reason I prefer the 2nd option as the filename you specify is the filename that is created.

SELECT p.*
FROM primary_table p LEFT JOIN second s ON p.ID = s.ID

If you want to get values in Javascript on frontend, you can use the native way to do it by using :

document.getElementsByName("movie")[0].value;

Where "movie" is the name of your input <input type="text" name="movie">

If you want to get it on angular.js controller, you can use;

$scope.movie

You just need to return standard ContentResult and set ContentType to "application/json". You can create custom ActionResult for it:

public class JsonStringResult : ContentResult
{
    public JsonStringResult(string json)
    {
        Content = json;
        ContentType = "application/json";
    }
}

And then return it's instance:

[HttpPost]
public JsonResult UpdateBatchSearchMembers()
{
    string returntext;
    if (!System.IO.File.Exists(path))
        returntext = Properties.Settings.Default.EmptyBatchSearchUpdate;
    else
        returntext = Properties.Settings.Default.ResponsePath;

    return new JsonStringResult(returntext);
}

You can use new Date().getTimezoneOffset()/60 for the timezone. There is also a toLocaleString() method for displaying a date using the user's locale.

I am new with HTML and CSS and I was also looking for solution for this, here what I find.

table,th,td {
   border: 1px solid black;
   border-spacing: 0
}
/* add border-radius to table only*/
table {
   border-radius: 25px    
}
/* then add border-radius to top left border of left heading cell */
th:first-child {
   border-radius: 25px 0 0 0
}
/* then add border-radius to top right border of right heading cell */
th:last-child {
   border-radius: 0 25px 0 0
}
/* then add border-radius to bottom left border of left cell of last row */
tr:last-child td:first-child {
   border-radius: 0 0 0 25px
}
/* then add border-radius to bottom right border of right cell of last row */
tr:last-child td:last-child {
   border-radius: 0 0 25px 0
}

I try it, guess what it works :)

For using the new progress bar

style="?android:attr/progressBarStyleHorizontal"

for the old grey color progress bar use

style="@android:style/Widget.ProgressBar.Horizontal"

in this one you have the option of changing the height by setting minHeight

The complete XML code is:

    <ProgressBar
    android:id="@+id/pbProcessing"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/tvProcessing"
    android:indeterminateOnly="true"/>

indeterminateOnly is set to true for getting indeterminate horizontal progress bar

In most of the cases, StringUtils.isBlank(str) from apache commons library would solve it. But if there is case, where input string being checked has null value within quotes, it fails to check such cases.

Take an example where I have an input object which was converted into string using String.valueOf(obj) API. In case obj reference is null, String.valueOf returns "null" instead of null.

When you attempt to use, StringUtils.isBlank("null"), API fails miserably, you may have to check for such use cases as well to make sure your validation is proper.

You can make the pagebreak conditional on knitting to PDF. This worked for me.

```{r, results='asis', eval=(opts_knit$get('rmarkdown.pandoc.to') == 'latex')}
cat('\\pagebreak')

    Column3 type3
)

INSERT INTO #TEMPTABLE

For same error code i had quite different reason, I'm sharing here to help

I had web api action like below

public IHttpActionResult GetBooks (int id)

I changed the method to accept two parameters category and author so i changed the parameters as below, i also put the attribute [Httppost]

public IHttpActionResult GetBooks (int category, int author)

I also changed ajax options like below and at this point i start getting error 405 method not allowed

var options = {
    url: '/api/books/GetBooks',
    type: 'POST',
    dataType: 'json',
    cache: false,
    traditional: true, 
    data: {
        category: 1,
        author: 15
    }
}

When i created class for web api action parameters like below error was gone

public class BookParam
{
    public int Category { get; set; }
    public int Author { get; set; }
}
public IHttpActionResult GetBooks (BookParam param)

If you want to keep the height of the DIV absolute, regardless of the amount of text inside use the following:

overflow: hidden;

   Dim ca As Integer = ListBox1.Items.Count().ToString
    While Not ca = 0
        ca = ca - 1
        ListBox1.Items.RemoveAt(ca)
    End While

       title: 'My Site',
       myCss: myCss
      });
     });

put this on template

   <%- myCss.style %>

just build style.css

  <style>
    body { 
     background-color: #D8D8D8;
     color: #444;

I try this for some custom css. It works for me

I done in this way

from keras.models import Sequential
from keras_contrib.losses import import crf_loss
from keras_contrib.metrics import crf_viterbi_accuracy

# To save model
model.save('my_model_01.hdf5')

# To load the model
custom_objects={'CRF': CRF,'crf_loss': crf_loss,'crf_viterbi_accuracy':crf_viterbi_accuracy}

# To load a persisted model that uses the CRF layer 
model1 = load_model("/home/abc/my_model_01.hdf5", custom_objects = custom_objects)

You can just go for String replace method.-

line1 = line1.replace("\"", "");

In Bootstrap 4 one should use the text-center class to align inline-blocks.

NOTE: text-align:center; defined in a custom class you apply to your parent element will work regardless of the Bootstrap version you are using. And that's exactly what .text-center applies.

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">_x000D_
_x000D_
<div class="container">_x000D_
  <div class="row">_x000D_
    <div class="col text-center">_x000D_
      <button class="btn btn-default">Centered button</button>_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

If the content to be centered is block or flex (not inline-), one could use flexbox to center it:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">_x000D_
_x000D_
<div class="d-flex justify-content-center">_x000D_
  <button class="btn btn-default">Centered button</button>_x000D_
</div>

... which applies display: flex; justify-content: center to parent.

Note: don't use .row.justify-content-center instead of .d-flex.justify-content-center, as .row applies negative margins on certain responsiveness intervals, which results into unexpected horizontal scrollbars (unless .row is a direct child of .container, which applies lateral padding to counteract the negative margin, on the correct responsiveness intervals). If you must use .row, for whatever reason, override its margin and padding with .m-0.p-0, in which case you end up with pretty much the same styles as .d-flex.

Important note: The second solution is problematic when the centered content (the button) exceeds the width of the parent (.d-flex) especially when the parent has viewport width, specifically because it makes it impossible to horizontally scroll to the start of the content (left-most).
So don't use it when the content to be centered could become wider than the available parent width and all content should be accessible.

printing a list can also cause this problem (im new in python, so it confused me a bit too):

>>>myList = ['\\']
>>>print myList
['\\']
>>>print ''.join(myList)
\ 

similarly:

>>>myList = ['\&']
>>>print myList
['\\&']
>>>print ''.join(myList)

There is no canonical answer, since XML fundamentally has no null concept. But I assume you want Xml/Object mapping (since object graphs have nulls); so the answer for you is "whatever your tool uses". If you write handling, that means whatever you prefer. For tools that use XML Schema, xsi:nil is the way to go. For most mappers, omitting matching element/attribute is the way to do it.

You can use AsyncFunc from Cactoos:

boolean matches = new AsyncFunc(
  x -> x.matches("something")
).apply("The text").get();

It will be executed at the background and the result will be available in get() as a Future.

Many people mentioned it, but I had to write it down. Isn't this most clear/most readable?

IEnumerable<Item> items = GetItems();
foreach (var item in items) item.DoStuff();

Short and simple(st).

Swift

// corner radius
blueView.layer.cornerRadius = 10

// border
blueView.layer.borderWidth = 1.0
blueView.layer.borderColor = UIColor.black.cgColor

// shadow
blueView.layer.shadowColor = UIColor.black.cgColor
blueView.layer.shadowOffset = CGSize(width: 3, height: 3)
blueView.layer.shadowOpacity = 0.7
blueView.layer.shadowRadius = 4.0

Exploring the options

Problem 1: Shadow gets clipped off

What if there are sublayers or subviews (like an image) whose content we want to clip to the bounds of our view?

We can accomplish this with

blueView.layer.masksToBounds = true

(Alternatively, blueView.clipsToBounds = true gives the same result.)

But, oh no! The shadow was also clipped off because it's outside of the bounds! What to do? What to do?

Solution

Use separate views for the shadow and the border. The base view is transparent and has the shadow. The border view clips any other subcontent that it has to its borders.

// add the shadow to the base view
baseView.backgroundColor = UIColor.clear
baseView.layer.shadowColor = UIColor.black.cgColor
baseView.layer.shadowOffset = CGSize(width: 3, height: 3)
baseView.layer.shadowOpacity = 0.7
baseView.layer.shadowRadius = 4.0

// add the border to subview
let borderView = UIView()
borderView.frame = baseView.bounds
borderView.layer.cornerRadius = 10
borderView.layer.borderColor = UIColor.black.cgColor
borderView.layer.borderWidth = 1.0
borderView.layer.masksToBounds = true
baseView.addSubview(borderView)

// add any other subcontent that you want clipped
let otherSubContent = UIImageView()
otherSubContent.image = UIImage(named: "lion")
otherSubContent.frame = borderView.bounds
borderView.addSubview(otherSubContent)

This gives the following result:

Problem 2: Poor performance

Adding rounded corners and shadows can be a performance hit. You can improve performance by using a predefined path for the shadow and also specifying that it be rasterized. The following code can be added to the example above.

baseView.layer.shadowPath = UIBezierPath(roundedRect: baseView.bounds, cornerRadius: 10).cgPath
baseView.layer.shouldRasterize = true
baseView.layer.rasterizationScale = UIScreen.main.scale

See this post for more details. See here and here also.

This answer was tested with Swift 4 and Xcode 9.

In case, if you need a no jquery solution

<label class="custom-file">
      <input type="file" id="myfile" class="custom-file-input" onchange="this.nextElementSibling.innerText = this.files[0].name">

</label>

From the official GitFaq:

Git has a rename command git mv, but that is just a convenience. The effect is indistinguishable from removing the file and adding another with different name and the same content

I had this error too, it was caused by an Any CPU exe referencing Any CPU assemblies that in turn referenced an x86 assembly.

The exception complained about a method on a class in MyApp.Implementations (Any CPU), which derived MyApp.Interfaces (Any CPU), but in fuslogvw.exe I found a hidden 'attempt to load program with an incorrect format' exception from MyApp.CommonTypes (x86) which is used by both.

How about this?

function getQueryVar(varName){
    // Grab and unescape the query string - appending an '&' keeps the RegExp simple
    // for the sake of this example.
    var queryStr = unescape(window.location.search) + '&';

    // Dynamic replacement RegExp
    var regex = new RegExp('.*?[&\\?]' + varName + '=(.*?)&.*');

    // Apply RegExp to the query string
    var val = queryStr.replace(regex, "$1");

    // If the string is the same, we didn't find a match - return false
    return val == queryStr ? false : val;
}

..then just call it with:

alert('Var "dest" = ' + getQueryVar('dest'));

I know this is a pretty old question, but I dealt with this recently. Let me know what you think of this solution.

I created a utility that lets me strongly type arguments and let them be optional. You basically wrap your function in a proxy. If you skip an argument, it's undefined. It may get quirky if you have multiple optional arguments with the same type right next to each other. (There are options to pass functions instead of types to do custom argument checks, as well as specifying default values for each parameter.)

This is what the implementation looks like:

function displayOverlay(/*message, timeout, callback*/) {
  return arrangeArgs(arguments, String, Number, Function, 
    function(message, timeout, callback) {
      /* ... your code ... */
    });
};

For clarity, here is what is going on:

function displayOverlay(/*message, timeout, callback*/) {
  //arrangeArgs is the proxy
  return arrangeArgs(
           //first pass in the original arguments
           arguments, 
           //then pass in the type for each argument
           String,  Number,  Function, 
           //lastly, pass in your function and the proxy will do the rest!
           function(message, timeout, callback) {

             //debug output of each argument to verify it's working
             console.log("message", message, "timeout", timeout, "callback", callback);

             /* ... your code ... */

           }
         );
};

You can view the arrangeArgs proxy code in my GitHub repository here:

Here is the utility function with some comments copied from the repository:

The two methods of adding do generate slightly different byte code:

  17: iconst_2
  18: iload         4
  20: iload         4
  22: imul
  23: imul
  24: iadd

For 2 * (i * i) vs:

  17: iconst_2
  18: iload         4
  20: imul
  21: iload         4
  23: imul
  24: iadd

For 2 * i * i.

And when using a JMH benchmark like this:

@Warmup(iterations = 5, batchSize = 1)
@Measurement(iterations = 5, batchSize = 1)
@Fork(1)
@BenchmarkMode(Mode.AverageTime)
@OutputTimeUnit(TimeUnit.MILLISECONDS)
@State(Scope.Benchmark)
public class MyBenchmark {

    @Benchmark
    public int noBrackets() {
        int n = 0;
        for (int i = 0; i < 1000000000; i++) {
            n += 2 * i * i;
        }
        return n;
    }

    @Benchmark
    public int brackets() {
        int n = 0;
        for (int i = 0; i < 1000000000; i++) {
            n += 2 * (i * i);
        }
        return n;
    }

}

The difference is clear:

# JMH version: 1.21
# VM version: JDK 11, Java HotSpot(TM) 64-Bit Server VM, 11+28
# VM options: <none>

Benchmark                      (n)  Mode  Cnt    Score    Error  Units
MyBenchmark.brackets    1000000000  avgt    5  380.889 ± 58.011  ms/op
MyBenchmark.noBrackets  1000000000  avgt    5  512.464 ± 11.098  ms/op

What you observe is correct, and not just an anomaly of your benchmarking style (i.e. no warmup, see How do I write a correct micro-benchmark in Java?)

Running again with Graal:

# JMH version: 1.21
# VM version: JDK 11, Java HotSpot(TM) 64-Bit Server VM, 11+28
# VM options: -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseJVMCICompiler

Benchmark                      (n)  Mode  Cnt    Score    Error  Units
MyBenchmark.brackets    1000000000  avgt    5  335.100 ± 23.085  ms/op
MyBenchmark.noBrackets  1000000000  avgt    5  331.163 ± 50.670  ms/op

You see that the results are much closer, which makes sense, since Graal is an overall better performing, more modern, compiler.

So this is really just up to how well the JIT compiler is able to optimize a particular piece of code, and doesn't necessarily have a logical reason to it.

You need to move type parameter to the method level to indicate that you have a generic method rather than generic class:

public class ArrayUtils {
    public static <T> E[] appendToArray(E[] array, E item) {
        E[] result = (E[])new Object[array.length+1];
        result[array.length] = item;
        return result;
    }
}

If you have php installed - you can use built-in server. Just open target dir with files and run

php -S localhost:8001

I used this code so I still could support older Android versions and use recreate() on newer Android versions.

Code:

public static void restartActivity(Activity activity){
    if (Build.VERSION.SDK_INT >= 11) {
        activity.recreate();
    } else {
        activity.finish();
        activity.startActivity(activity.getIntent());
    }
}

Sample:

import android.app.Activity;
import android.os.Build;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {
    private Activity mActivity;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mActivity = MainActivity.this;

        Button button = (Button) findViewById(R.id.restart_button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                restartActivity(mActivity);
            }
        });
    }

    public static void restartActivity(Activity activity) {
        if (Build.VERSION.SDK_INT >= 11) {
            activity.recreate();
        } else {
            activity.finish();
            activity.startActivity(activity.getIntent());
        }
    }
}

WORKING ALWAYS ON TOP IMAGE BUTTON

first of all sorry for my english

i edit your codes and make working image button that listens his touch event do not give touch control to his background elements.

also it gives touch listeners to out of other elements

button alingments are bottom and left

you can chage alingments but you need to chages cordinats in touch event in the if element

just use a subquery right there like:

this query will auto-update the nulls

ALTER TABLE mytable ADD COLUMN mycolumn character varying(50) DEFAULT 'whatever' NOT NULL;

This question was posted in 2015. In 2018, node recognizes both .js and .ts. So, running node file.ts will also run.

This is due to IFS (Internal Field Separator) variable which contains newline.

$ cat xx1
1
2

$ A=`cat xx1`
$ echo $A
1 2

$ echo "|$IFS|"
|       
|

A workaround is to reset IFS to not contain the newline, temporarily:

$ IFSBAK=$IFS
$ IFS=" "
$ A=`cat xx1` # Can use $() as well
$ echo $A
1
2
$ IFS=$IFSBAK

To REVERT this horrible change for IFS:

IFS=$IFSBAK

Does it absolutely have to be 100% functional and fluent? If not, how about this, which is about as short as it gets:

Map<String, Integer> output = new HashMap<>();
input.forEach((k, v) -> output.put(k, Integer.valueOf(v));

(if you can live with the shame and guilt of combining streams with side-effects)

You can use QPalette, however you must set setAutoFillBackground(true); to enable background color

QPalette sample_palette;
sample_palette.setColor(QPalette::Window, Qt::white);
sample_palette.setColor(QPalette::WindowText, Qt::blue);

sample_label->setAutoFillBackground(true);
sample_label->setPalette(sample_palette);
sample_label->setText("What ever text");

It works fine on Windows and Ubuntu, I haven't played with any other OS.

Note: Please see QPalette, color role section for more details

Use the json module to produce JSON output:

import json

with open(outputfilename, 'wb') as outfile:
    json.dump(row, outfile)

This writes the JSON result directly to the file (replacing any previous content if the file already existed).

If you need the JSON result string in Python itself, use json.dumps() (added s, for 'string'):

json_string = json.dumps(row)

The L is just Python syntax for a long integer value; the json library knows how to handle those values, no L will be written.

Demo string output:

>>> import json
>>> row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]
>>> json.dumps(row)
'[1, [0.1, 0.2], [[1234, 1], [134, 2]]]'

To prevent unexpected margins and other browser-specific behavior in the future, I'd recommend to include reset.css in your stylesheets.

Be aware that you'll have to set the h[1..6] font size and weight to make headings look like headings again after that, and many other things.

Grep is useful if you want to quickly search for lines that match in a file. It can also return some other simple information like matching line numbers, match count, and file name lists.

Awk is an entire programming language built around reading CSV-style files, processing the records, and optionally printing out a result data set. It can do many things but it is not the easiest tool to use for simple tasks.

Sed is useful when you want to make changes to a file based on regular expressions. It allows you to easily match parts of lines, make modifications, and print out results. It's less expressive than awk but that lends it to somewhat easier use for simple tasks. It has many more complicated operators you can use (I think it's even turing complete), but in general you won't use those features.

Another (async) approach, using Identity's UserManager and SigninManager to reflect the change in the Identity cookie (and to optionally remove claims from db table AspNetUserClaims):

// Get User and a claims-based identity
ApplicationUser user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
var Identity = new ClaimsIdentity(User.Identity);

// Remove existing claim and replace with a new value
await UserManager.RemoveClaimAsync(user.Id, Identity.FindFirst("AccountNo"));
await UserManager.AddClaimAsync(user.Id, new Claim("AccountNo", value));

// Re-Signin User to reflect the change in the Identity cookie
await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);

// [optional] remove claims from claims table dbo.AspNetUserClaims, if not needed
var userClaims = UserManager.GetClaims(user.Id);
if (userClaims.Any())
{
  foreach (var item in userClaims)
  {
    UserManager.RemoveClaim(user.Id, item);
  }
}

var startDate = "06/27/2007";
startDate = new Date(startDate);

console.log(startDate);

We can hide close button on form by setting this.ControlBox=false;

Note that this hides all of those sizing buttons. Not just the X. In some cases that may be fine.

A good way to test if a string is a correct date is to use the command date:

if date -d "${DATE}" >/dev/null 2>&1
then
  # do what you need to do with your date
else
  echo "${DATE} incorrect date" >&2
  exit 1
fi

from comment: one can use formatting

if [ "2017-01-14" == $(date -d "2017-01-14" '+%Y-%m-%d') ] 

This thing worked for me. No any external liabraries used

         $ext = substr($str,$i+1,$l);
         return $ext;

I faced the same problem. From some research that I did, I realized that my computer does not support virtualization. So I had to install BLUESTACKS. Believe me it worked...you can also try it.

1. Just go to your directory C:\Android\sdk\platform-tools and double click adb
2. Ensure that your bluestack is running.
3. When you try to run the project, it automatically shows up to run with the bluestacks....just choose the bluestack and you are done.

If you want the setup of bluestack, just google it you can have a number of sites to download from for free.

I have answered this question here: https://stackoverflow.com/a/38238785/1773972

Basically use

StringUtils.substringBetween(str, "<%=", "%>");

This requirs using "Apache commons lang" library: https://mvnrepository.com/artifact/org.apache.commons/commons-lang3/3.4

This library has a lot of useful methods for working with string, you will really benefit from exploring this library in other areas of your java code !!!

That's no struts related problem but rather plain HMTL/CSS.

I'm not HTML or CSS expert, but I guess you could use a div with a border on the left or right side only.

I tried the binding according to the answer by @Szymon but It did not work for me. I tried basicHttpsBinding which is new in .net 4.5 and It solved the issue. Here is the complete configuration that works for me.

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <basicHttpsBinding>
        <binding name="basicHttpsBindingForYourService">
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"/>
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>
    <services>
      <service name="YourServiceName">
        <endpoint address="" binding="basicHttpsBinding" bindingName="basicHttpsBindingForYourService" contract="YourContract" />
      </service>
    </services>   
</system.serviceModel>

FYI: My application's target framework is 4.5.1. IIS web site that I created to deploy this wcf service only has https binding enabled.

Steps (in VS Code 1.29.x):

I've done this kind of thing with a form that contains a TextBox.

So if you wanted to put this in say cell H1, then use:

ActiveSheet.Range("H1").Value = txtBoxName.Text

man ssh gives me this options would could be useful.

-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).

So you could create an alias in your bash config with something like

alias ssh="ssh -i /path/to/private_key"

I haven't looked into a ssh configuration file, but like the -i option this too could be aliased

-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

Simply, you use ADB, as follows:

adb install <path to apk>

Also see the section Installing an Application in Android Debug Bridge.

Another way :

decimal.Round(decimalvalue, 2, MidpointRounding.AwayFromZero);

Another solution would be the usage of std::make_move_iterator to build a new vector (C++11 )

    int main(){

      std::map<std::string, int> map;
       //Populate map

      std::vector<std::pair<std::string, int>> v {std::make_move_iterator(begin(map)),
                                      std::make_move_iterator(end(map))};
       // Create a vector with the map parameters

       sort(begin(v), end(v),
             [](auto p1, auto p2){return p1.second > p2.second;});
       // Using sort + lambda function to return an ordered vector 
       // in respect to the int value that is now the 2nd parameter 
       // of our newly created vector v
  }

libcurl also provides CURLOPT_COOKIELIST which extracts all known cookies. All you need is to make sure the PHP/CURL binding can use it.

You could json encode a generic object.

$post_data = new stdClass();
$post_data->item = new stdClass();
$post_data->item->item_type_id = $item_type;
$post_data->item->string_key = $string_key;
$post_data->item->string_value = $string_value;
$post_data->item->string_extra = $string_extra;
$post_data->item->is_public = $public;
$post_data->item->is_public_for_contacts = $public_contacts;
echo json_encode($post_data);

The problem is that PHP mail() function has a very limited functionality. There are several ways to send mail from PHP.

1. mail() uses SMTP server on your system. There are at least two servers you can use on Windows: hMailServer and xmail. I spent several hours configuring and getting them up. First one is simpler in my opinion. Right now, hMailServer is working on Windows 7 x64.
2. mail() uses SMTP server on remote or virtual machine with Linux. Of course, real mail service like Gmail doesn't allow direct connection without any credentials or keys. You can set up virtual machine or use one located in your LAN. Most linux distros have mail server out of the box. Configure it and have fun. I use default exim4 on Debian 7 that listens its LAN interface.
3. Mailing libraries use direct connections. Libs are easier to set up. I used SwiftMailer and it perfectly sends mail from Gmail account. I think that PHPMailer is pretty good too.

No matter what choice is your, I recommend you use some abstraction layer. You can use PHP library on your development machine running Windows and simply mail() function on production machine with Linux. Abstraction layer allows you to interchange mail drivers depending on system which your application is running on. Create abstract MyMailer class or interface with abstract send() method. Inherit two classes MyPhpMailer and MySwiftMailer. Implement send() method in appropriate ways.

You should find all HTTP headers in the $_SERVER global variable prefixed with HTTP_ uppercased and with dashes (-) replaced by underscores (_).

For instance your X-Requested-With can be found in:

$_SERVER['HTTP_X_REQUESTED_WITH']

It might be convenient to create an associative array from the $_SERVER variable. This can be done in several styles, but here's a function that outputs camelcased keys:

$headers = array();
foreach ($_SERVER as $key => $value) {
    if (strpos($key, 'HTTP_') === 0) {
        $headers[str_replace(' ', '', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))))] = $value;
    }
}

Now just use $headers['XRequestedWith'] to retrieve the desired header.

As the question and user3490026's answer are a top search hit, I have made a reproducible example and a brief illustration of the suggestions made so far, together with a solution that explicitly addresses the OP's question.

One of the things that ggplot2 does and which can be confusing is that it automatically blends certain legends when they are associated with the same variable. For instance, factor(gear) appears twice, once for linetype and once for fill, resulting in a combined legend. By contrast, gear has its own legend entry as it is not treated as the same as factor(gear). The solutions offered so far usually work well. But occasionally, you may need to override the guides. See my last example at the bottom.

# reproducible example:
library(ggplot2)
p <- ggplot(data = mtcars, aes(x = mpg, y = disp, group = gear)) +
geom_point(aes(color = vs)) +
geom_point(aes(shape = factor(cyl))) +
geom_line(aes(linetype = factor(gear))) +
geom_smooth(aes(fill = factor(gear), color = gear)) + 
theme_bw() 

Remove all legends: @user3490026

p + theme(legend.position = "none")

Remove all legends: @duhaime

p + guides(fill = FALSE, color = FALSE, linetype = FALSE, shape = FALSE)

Turn off legends: @Tjebo

ggplot(data = mtcars, aes(x = mpg, y = disp, group = gear)) +
geom_point(aes(color = vs), show.legend = FALSE) +
geom_point(aes(shape = factor(cyl)), show.legend = FALSE) +
geom_line(aes(linetype = factor(gear)), show.legend = FALSE) +
geom_smooth(aes(fill = factor(gear), color = gear), show.legend = FALSE) + 
theme_bw() 

Remove fill so that linetype becomes visible

p + guides(fill = FALSE)

Same as above via the scale_fill_ function:

p + scale_fill_discrete(guide = FALSE)

And now one possible answer to the OP's request

"to keep the legend of one layer (smooth) and remove the legend of the other (point)"

Turn some on some off ad-hoc post-hoc

p + guides(fill = guide_legend(override.aes = list(color = NA)), 
           color = FALSE, 
           shape = FALSE)  

Create a C# class that maps to your Json and use Newsoft JsonConvert to Deserialise it.

For example:

public Class MyResponse
{
    public Meta Meta { get; set; }
    public Response Response { get; set; }
}

The easiest way is to add the:

$('#ID').css("height", $(document).height());

after the correct page height is determined by the browser. If the document height is changed once more re-run the above code.

AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.

As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.

So AArch64 and ARM64 refer to the same thing.

When you are filling the ArrayList, use a condition for each element. For example:

    ArrayList< Integer > al = new ArrayList< Integer >(); 

    // fill 1 
    for ( int i = 0; i <= 5; i++ ) 
        if ( !al.contains( i ) ) 
            al.add( i ); 

    // fill 2 
    for (int i = 0; i <= 10; i++ ) 
        if ( !al.contains( i ) ) 
            al.add( i ); 

    for( Integer i: al )
    {
        System.out.print( i + " ");     
    }

We will get an array {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

To complete oscarbranson's answer: it's possible to automatically pick console or notebook versions of progress bar depending on where it's being run from:

from tqdm.autonotebook import tqdm

Surprisingly, square brackets in DocumentRoot (and related, like <Directory>) paths can also cause error 403:

• DocumentRoot "P:/TRY/web/fatfree/from_github/fatfree-master[bang]" failed with 403, while
• DocumentRoot "P:/TRY/web/fatfree/from_github/fatfree-master" worked fine.

(I didn't bother figuring out the Apache path escaping, if any, just renamed the path instead. If anyone knows, comments are welcome.)

You can use Watchtower to watch for updates to the image a container is instantiated from and automatically pull the update and restart the container using the updated image. However, that doesn't solve the problem of rebuilding your own custom images when there's a change to the upstream image it's based on. You could view this as a two-part problem: (1) knowing when an upstream image has been updated, and (2) doing the actual image rebuild. (1) can be solved fairly easily, but (2) depends a lot on your local build environment/practices, so it's probably much harder to create a generalized solution for that.

If you're able to use Docker Hub's automated builds, the whole problem can be solved relatively cleanly using the repository links feature, which lets you trigger a rebuild automatically when a linked repository (probably an upstream one) is updated. You can also configure a webhook to notify you when an automated build occurs. If you want an email or SMS notification, you could connect the webhook to IFTTT Maker. I found the IFTTT user interface to be kind of confusing, but you would configure the Docker webhook to post to https://maker.ifttt.com/trigger/`docker_xyz_image_built`/with/key/`your_key`.

If you need to build locally, you can at least solve the problem of getting notifications when an upstream image is updated by creating a dummy repo in Docker Hub linked to your repo(s) of interest. The sole purpose of the dummy repo would be to trigger a webhook when it gets rebuilt (which implies one of its linked repos was updated). If you're able to receive this webhook, you could even use that to trigger a rebuild on your side.

A stack is a LIFO (last in, first out - the last entry you push on to the stack is the first one you get back when you pop) data structure that is typically used to hold stack frames (bits of the stack that belong to the current function).

This includes, but is not limited to:

• the return address.
• a place for a return value.
• passed parameters.
• local variables.

You push items onto the stack and pop them off. In a microprocessor, the stack can be used for both user data (such as local variables and passed parameters) and CPU data (such as return addresses when calling subroutines).

The actual implementation of a stack depends on the microprocessor architecture. It can grow up or down in memory and can move either before or after the push/pop operations.

Operation which typically affect the stack are:

• subroutine calls and returns.
• interrupt calls and returns.
• code explicitly pushing and popping entries.
• direct manipulation of the SP register.

Consider the following program in my (fictional) assembly language:

Addr  Opcodes   Instructions    ; Comments
----  --------  --------------  ----------
                                ; 1: pc<-0000, sp<-8000
0000  01 00 07  load r0,7       ; 2: pc<-0003, r0<-7
0003  02 00     push r0         ; 3: pc<-0005, sp<-7ffe, (sp:7ffe)<-0007
0005  03 00 00  call 000b       ; 4: pc<-000b, sp<-7ffc, (sp:7ffc)<-0008
0008  04 00     pop r0          ; 7: pc<-000a, r0<-(sp:7ffe[0007]), sp<-8000
000a  05        halt            ; 8: pc<-000a
000b  06 01 02  load r1,[sp+2]  ; 5: pc<-000e, r1<-(sp+2:7ffe[0007])
000e  07        ret             ; 6: pc<-(sp:7ffc[0008]), sp<-7ffe

Now let's follow the execution, describing the steps shown in the comments above:

1. This is the starting condition where the program counter is zero and the stack pointer is 8000 (all these numbers are hexadecimal).
2. This simply loads register r0 with the immediate value 7 and moves to the next step (I'll assume that you understand the default behavior will be to move to the next step unless otherwise specified).
3. This pushes r0 onto the stack by reducing the stack pointer by two then storing the value of the register to that location.
4. This calls a subroutine. What would have been the program counter is pushed on to the stack in a similar fashion to r0 in the previous step and then the program counter is set to its new value. This is no different to a user-level push other than the fact it's done more as a system-level thing.
5. This loads r1 from a memory location calculated from the stack pointer - it shows a way to pass parameters to functions.
6. The return statement extracts the value from where the stack pointer points and loads it into the program counter, adjusting the stack pointer up at the same time. This is like a system-level pop (see next step).
7. Popping r0 off the stack involves extracting the value from where the stack pointer points then adjusting that stack pointer up.
8. Halt instruction simply leaves program counter where it is, an infinite loop of sorts.

Hopefully from that description, it will become clear. Bottom line is: a stack is useful for storing state in a LIFO way and this is generally ideal for the way most microprocessors do subroutine calls.

Unless you're a SPARC of course, in which case you use a circular buffer for your stack :-)

Update: Just to clarify the steps taken when pushing and popping values in the above example (whether explicitly or by call/return), see the following examples:

LOAD R0,7
PUSH R0
                     Adjust sp       Store val
sp-> +--------+      +--------+      +--------+
     |  xxxx  |  sp->|  xxxx  |  sp->|  0007  |
     |        |      |        |      |        |
     |        |      |        |      |        |
     |        |      |        |      |        |
     +--------+      +--------+      +--------+

POP R0
                     Get value       Adjust sp
     +--------+      +--------+  sp->+--------+
sp-> |  0007  |  sp->|  0007  |      |  0007  |
     |        |      |        |      |        |
     |        |      |        |      |        |
     |        |      |        |      |        |
     +--------+      +--------+      +--------+

matrix.size according to the numpy docs returns the Number of elements in the array. Hope that helps.
