As far as I can tell this will only work on newer versions of Android, so you will probably have to figure out a different way to do it. This solution works for me on 4.4, but not on 4.0 or 2.3.3, so this will not be a useful way to go about sharing content for an app that's meant to run on any Android device.

In manifest.xml:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mydomain.myapp.SharingActivity"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Take careful note of how you specify the authorities. You must specify the activity from which you will create the URI and launch the share intent, in this case the activity is called SharingActivity. This requirement is not obvious from Google's docs!

file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="just_a_name" path=""/>
</paths>

Be careful how you specify the path. The above defaults to the root of your private internal storage.

In SharingActivity.java:

Uri contentUri = FileProvider.getUriForFile(getActivity(),
"com.mydomain.myapp.SharingActivity", myFile);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("image/jpeg");
shareIntent.putExtra(Intent.EXTRA_STREAM, contentUri);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, "Share with"));

In this example we are sharing a JPEG image.

Finally it is probably a good idea to assure yourself that you have saved the file properly and that you can access it with something like this:

File myFile = getActivity().getFileStreamPath("mySavedImage.jpeg");
if(myFile != null){
    Log.d(TAG, "File found, file description: "+myFile.toString());
}else{
    Log.w(TAG, "File not found!");
}

select convert(varchar(5),dateadd(mi,DATEDIFF(minute, FirstDate,LastDate),'00:00'),114)    

0 is, by definition, a magic number. EXIT_SUCCESS is almost universally equal to 0, happily enough. So why not just return/exit 0?

exit(EXIT_SUCCESS); is abundantly clear in meaning.

exit(0); on the other hand, is counterintuitive in some ways. Someone not familiar with shell behavior might assume that 0 == false == bad, just like every other usage of 0 in C. But no - in this one special case, 0 == success == good. For most experienced devs, not going to be a problem. But why trip up the new guy for absolutely no reason?

tl;dr - if there's a defined constant for your magic number, there's almost never a reason not to used the constant in the first place. It's more searchable, often clearer, etc. and it doesn't cost you anything.

If you are using skaffold, use 'context:' to specify context location for each image dockerfile - context: ../../../

            apiVersion: skaffold/v2beta4
            kind: Config
            metadata:
                name: frontend
            build:
                artifacts:
                    - image: nginx-angular-ui
                      context: ../../../
                      sync:
                          # A local build will update dist and sync it to the container
                          manual:
                              - src: './dist/apps'
                                dest: '/usr/share/nginx/html'
                      docker:
                          dockerfile: ./tools/pipelines/dockerfile/nginx.dev.dockerfile
                    - image: webapi/image
                      context: ../../../../api/
                      docker:
                          dockerfile: ./dockerfile
            deploy:
                kubectl:
                    manifests:
                        - ./.k8s/*.yml

skaffold run -f ./skaffold.yaml

I followed this simple steps to do this stuff.

1. Create interface like DialogFragmentCallbackInterface with some method like callBackMethod(Object data). Which you would calling to pass data.
2. Now you can implement DialogFragmentCallbackInterface interface in your fragment like MyFragment implements DialogFragmentCallbackInterface

3. At time of DialogFragment creation set your invoking fragment MyFragment as target fragment who created DialogFragment use myDialogFragment.setTargetFragment(this, 0) check setTargetFragment (Fragment fragment, int requestCode)

   MyDialogFragment dialogFrag = new MyDialogFragment();
   dialogFrag.setTargetFragment(this, 1); 
   

4. Get your target fragment object into your DialogFragment by calling getTargetFragment() and cast it to DialogFragmentCallbackInterface.Now you can use this interface to send data to your fragment.

   DialogFragmentCallbackInterface callback = 
              (DialogFragmentCallbackInterface) getTargetFragment();
   callback.callBackMethod(Object data);
   

   That's it all done! just make sure you have implemented this interface in your fragment.

You can check it with irb:

$ irb
>> 2 / 3
=> 0
>> 2.to_f / 3
=> 0.666666666666667
>> 2 / 3.to_f
=> 0.666666666666667

Its blank because you are writing to file. you should write to output using php://output instead and also send header information to indicate that it's csv.

Example

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');
$data = array(
        'aaa,bbb,ccc,dddd',
        '123,456,789',
        '"aaa","bbb"'
);

$fp = fopen('php://output', 'wb');
foreach ( $data as $line ) {
    $val = explode(",", $line);
    fputcsv($fp, $val);
}
fclose($fp);

Well, using the HTML validator at w3.org, specific to HTML5, IDs must be unique

Consider the following...

<!DOCTYPE html> 
<html>
    <head>
        <meta charset="UTF-8">
        <title>MyTitle</title> 
    </head>
    <body>
        <div id="x">Barry</div>
        <div id="x">was</div>
        <div id="x">here</div>
    </body>
</html>

the validator responds with ...

Line 9, Column 14: Duplicate ID x.      <div id="x">was</div>
Warning Line 8, Column 14: The first occurrence of ID x was here.       <div id="x">Barry</div>
Error Line 10, Column 14: Duplicate ID x.       <div id="x">here</div>
Warning Line 8, Column 14: The first occurrence of ID x was here.       <div id="x">Barry</div>

... but the OP specifically stated - what about different element types. So consider the following HTML...

<!DOCTYPE html> 
<html>
    <head>
        <meta charset="UTF-8">
        <title>MyTitle</title> 
    </head>
    <body>
        <div id="x">barry
            <span id="x">was here</span>
        </div>
    </body>
</html>

... the result from the validator is...

Line 9, Column 16: Duplicate ID x.          <span id="x">was here</span>
Warning Line 8, Column 14: The first occurrence of ID x was here.       <div id="x">barry

Conclusion:

In either case (same element type, or different element type), if the id is used more than once it is not considered valid HTML5.

For those looking for a general strategy for reading and writing a string to file:

First, get a file object

You'll need the storage path. For the internal storage, use:

File path = context.getFilesDir();

For the external storage (SD card), use:

File path = context.getExternalFilesDir(null);

Then create your file object:

File file = new File(path, "my-file-name.txt");

Write a string to the file

FileOutputStream stream = new FileOutputStream(file);
try {
    stream.write("text-to-write".getBytes());
} finally {
    stream.close();
}

Or with Google Guava

String contents = Files.toString(file, StandardCharsets.UTF_8);

Read the file to a string

int length = (int) file.length();

byte[] bytes = new byte[length];

FileInputStream in = new FileInputStream(file);
try {
    in.read(bytes);
} finally {
    in.close();
}

String contents = new String(bytes);   

Or if you are using Google Guava

String contents = Files.toString(file,"UTF-8");

For completeness I'll mention

String contents = new Scanner(file).useDelimiter("\\A").next();

which requires no libraries, but benchmarks 50% - 400% slower than the other options (in various tests on my Nexus 5).

Notes

For each of these strategies, you'll be asked to catch an IOException.

The default character encoding on Android is UTF-8.

If you are using external storage, you'll need to add to your manifest either:

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

or

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

Write permission implies read permission, so you don't need both.

I think what you want to do is

<link rel="stylesheet" type="text/css" href="font/font-face/my-font-face.css">

There is no difference, under the hood it's all varlena (variable length array).

Check this article from Depesz: http://www.depesz.com/index.php/2010/03/02/charx-vs-varcharx-vs-varchar-vs-text/

A couple of highlights:

To sum it all up:

• char(n) – takes too much space when dealing with values shorter than n (pads them to n), and can lead to subtle errors because of adding trailing spaces, plus it is problematic to change the limit
• varchar(n) – it's problematic to change the limit in live environment (requires exclusive lock while altering table)
• varchar – just like text
• text – for me a winner – over (n) data types because it lacks their problems, and over varchar – because it has distinct name

The article does detailed testing to show that the performance of inserts and selects for all 4 data types are similar. It also takes a detailed look at alternate ways on constraining the length when needed. Function based constraints or domains provide the advantage of instant increase of the length constraint, and on the basis that decreasing a string length constraint is rare, depesz concludes that one of them is usually the best choice for a length limit.

The guarantees the standard gives you go like this:

1 == sizeof(char) <= sizeof(short) <= sizeof (int) <= sizeof(long) <= sizeof(long long)

So it's perfectly valid for sizeof (int) and sizeof (long) to be equal, and many platforms choose to go with this approach. You will find some platforms where int is 32 bits, long is 64 bits, and long long is 128 bits, but it seems very common for sizeof (long) to be 4.

(Note that long long is recognized in C from C99 onwards, but was normally implemented as an extension in C++ prior to C++11.)

I had the same issue. I am currently using Asp.net Core 2.2. I solved this problem with the following piece of code.

using Microsoft.AspNetCore.Identity;
var user = await _userManager.FindByEmailAsync(User.Identity.Name);

I hope this will be useful to someone.

The erase method on std::vector is overloaded, so it's probably clearer to call

vec.erase(vec.begin() + index);

when you only want to erase a single element.

If you wish dialog box to be re-activated for the page you set as prevent dialog box to show.

Chrome: select settings, a google page for chrome will open with all your settings for chrome.

At the very bottom, go to advance settings and at the bottom of the advance settings you may click on Resset Browser Settings... this will make dialog box appear as they should.

You're talking about histograms, but this doesn't quite make sense. Histograms and bar charts are different things. An histogram would be a bar chart representing the sum of values per year, for example. Here, you just seem to be after bars.

Here is a complete example from your data that shows a bar of for each required value at each date:

import pylab as pl
import datetime

data = """0 14-11-2003
1 15-03-1999
12 04-12-2012
33 09-05-2007
44 16-08-1998
55 25-07-2001
76 31-12-2011
87 25-06-1993
118 16-02-1995
119 10-02-1981
145 03-05-2014"""

values = []
dates = []

for line in data.split("\n"):
    x, y = line.split()
    values.append(int(x))
    dates.append(datetime.datetime.strptime(y, "%d-%m-%Y").date())

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(dates, values, width=100)
ax.xaxis_date()

You need to parse the date with strptime and set the x-axis to use dates (as described in this answer).

If you're not interested in having the x-axis show a linear time scale, but just want bars with labels, you can do this instead:

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(range(len(dates)), values)

EDIT: Following comments, for all the ticks, and for them to be centred, pass the range to set_ticks (and move them by half the bar width):

fig = pl.figure()
ax = pl.subplot(111)
width=0.8
ax.bar(range(len(dates)), values, width=width)
ax.set_xticks(np.arange(len(dates)) + width/2)
ax.set_xticklabels(dates, rotation=90)

I do not have an @github.com address

You don't have to: the @ is the separator between the username:password and the domain.
It is not an email address.

A full GitHub https url would be:

https://username:[email protected]/username/reponame.git

Without the password (which would then be asked on the command line), that would gave:

https://[email protected]/username/reponame.git

But again, [email protected] isn't an email address, just the first part of the credentials.

Make sure the case of your username and reponame is correct: it is case sensitive.

Note that you can store and encrypt your credentials in a .netrc.gpg (or _netrc.gpg on Windows) if you don't want to put said credentials in clear in the url.
See "Is there a way to skip password typing when using https://github".

A JIT compiler runs after the program has started and compiles the code (usually bytecode or some kind of VM instructions) on the fly (or just-in-time, as it's called) into a form that's usually faster, typically the host CPU's native instruction set. A JIT has access to dynamic runtime information whereas a standard compiler doesn't and can make better optimizations like inlining functions that are used frequently.

This is in contrast to a traditional compiler that compiles all the code to machine language before the program is first run.

To paraphrase, conventional compilers build the whole program as an EXE file BEFORE the first time you run it. For newer style programs, an assembly is generated with pseudocode (p-code). Only AFTER you execute the program on the OS (e.g., by double-clicking on its icon) will the (JIT) compiler kick in and generate machine code (m-code) that the Intel-based processor or whatever will understand.

Once you set your Global Jenkins credentials, you can apply this step:

stage('Update GIT') {
  steps {
    script {
      catchError(buildResult: 'SUCCESS', stageResult: 'FAILURE') {
        withCredentials([usernamePassword(credentialsId: 'example-secure', passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
            def encodedPassword = URLEncoder.encode("$GIT_PASSWORD",'UTF-8')
            sh "git config user.email [email protected]"
            sh "git config user.name example"
            sh "git add ."
            sh "git commit -m 'Triggered Build: ${env.BUILD_NUMBER}'"
            sh "git push https://${GIT_USERNAME}:${encodedPassword}@github.com/${GIT_USERNAME}/example.git"
        }
      }
    }
  }
}

install Homebrew, open Terminal or your favorite OSX terminal emulator and run

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

insert the Homebrew directory at the top of your PATH environment variable. You can do this by adding the following line at the bottom of your ~/.profile file

export PATH=/usr/local/bin:/usr/local/sbin:$PATH

Now, we can install Python 2.7:

$ brew install python

Get pip repository:

$ git clone https://github.com/pypa/pip

install pip:

$sudo easy_install pip

Just a side note to the discussion about JVM and JIT Compilation. This is the same principle as with C# and the CLR and to some extent in Python, and when somebody says that the code runs "directly on hardware" that is actually true in that instructions that is already compiled will be able to take advantage of optimization on the machine/cpu it's being run on. So even if the initial compilation of a module is rather slow, the next time this module is run, the code being executed runs at native speed and thus runs directly on hardware so to say.

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

I came here with a similar question/problem, but I only needed a single value to be stored from the query, not an array/table of results as in the orig post. I was able to use the table method above for a single value, however I have stumbled upon an easier way to store a single value.

declare @myVal int; set @myVal = isnull((select a from table1), 0);

Make sure to default the value in the isnull statement to a valid type for your variable, in my example the value in table1 that we're storing is an int.

Use this. Beware of i's larger than 9, as these will require a char array with more than 2 elements to avoid a buffer overrun.

char c[2];
int i=1;
sprintf(c, "%d", i);

Escape with a double backslash

R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat.

y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab:    , newline: 
## , unicode point: €

Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1

To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.

grepl("\\[", "a[b")
## [1] TRUE

To match backslashes, you need to double escape, resulting in four backslashes.

grepl("\\\\", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

The rebus package contains constants for each of the special characters to save you mistyping slashes.

library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"

For more examples see:

?SpecialCharacters

Your problem can be solved this way:

library(rebus)
grepl(OPEN_BRACKET, "a[b")

Form a character class

You can also wrap the special characters in square brackets to form a character class.

grepl("[?]", "a?b")
## [1] TRUE

Two of the special characters have special meaning inside character classes: \ and ^.

Backslash still needs to be escaped even if it is inside a character class.

grepl("[\\\\]", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

Caret only needs to be escaped if it is directly after the opening square bracket.

grepl("[ ^]", "a^b")  # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b") 
## [1] TRUE

rebus also lets you form a character class.

char_class("?")
## <regex> [?]

Use a pre-existing character class

If you want to match all punctuation, you can use the [:punct:] character class.

grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE

stringi maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

You can also use the cross-platform syntax for accessing a UGC.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

Use \Q \E escapes

Placing characters between \\Q and \\E makes the regular expression engine treat them literally rather than as regular expressions.

grepl("\\Q.\\E", "a.b")
## [1] TRUE

rebus lets you write literal blocks of regular expressions.

literal(".")
## <regex> \Q.\E

Don't use regular expressions

Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:

grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")

$query = "INSERT INTO myTable VALUES (NULL,'Fname', 'Lname', 'Website')";

Just leaving the value of the AI primary key NULL will assign an auto incremented value.

For those who like to work close to the metal, here is a command that will clear out the unwanted soot, without needing any special tools or scripts:

adb logcat "eglCodecCommon:S"

The results container div has position: relative meaning it is still in the document flow and will change the layout of elements around it. You need to use position: absolute to achieve a 'floating' effect.

You should also check the markup you're using, you have phantom <li>s with no container <ul>, you could probably replace both the div#suggestions and div#autoSuggestionsList with a single <ul> and get the desired result.

This can now be done as of docker-compose v2+ as part of the build object;

docker-compose.yml

version: '2'
services:
    my_image_name:
        build:
            context: . #current dir as build context
            args:
                var1: 1
                var2: c

See the docker compose docs.

In the above example "var1" and "var2" will be sent to the build environment.

Note: any env variables (specified by using the environment block) which have the same name as args variable(s) will override that variable.

If you are using Eclipse , you can try the below 7 steps to get a .exe file for Windows.

Now you have a JAR file. Use java -jar path/jarname.jar to execute.

If you want to convert this to .exe, you can try http://sourceforge.net/projects/launch4j/files/launch4j-3/

STEP7: Give the .xml file an appropriate name and click "Save". The .xml file is standard, don't worry about it. Your executable file will now be created!

var node = document.getElementsByClassName("second")[0].firstElementChild

Disclaimer: Browser compliance on getElementsByClassName and firstElementChild are shaky. DOM-shims fix those problems though.

I wrote this so I could edit all tables and columns to null at once:

then
'alter table  [' + so.name + '] alter column [' + sc.name + '] ' + st.name + '(MAX) NULL'

then
'alter table  [' + so.name + '] alter column [' + sc.name + '] ' + st.name + '(' + cast(sc.max_length as varchar(4)) + ') NULL'
else
'alter table  [' + so.name + '] alter column [' + sc.name + '] ' + st.name + ' NULL'
end as query

inner join sys.types st on st.system_type_id = sc.system_type_id
inner join sys.objects so on so.object_id = sc.object_id
where so.type = 'U'
and st.name <> 'timestamp'
order by st.name

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

import { HttpClient } from '@angular/common/http';

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

This is an old question, but because the existing answers could be very dangerous, I wanted to leave this answer for future folks who might stumble in here...

The answers based on using an Object as a HashMap are broken and can cause extremely nasty consequences if you use anything other than a String as the key. The problem is that Object properties are coerced to Strings using the .toString method. This can lead to the following nastiness:

function MyObject(name) {
  this.name = name;
};
var key1 = new MyObject("one");
var key2 = new MyObject("two");

var map = {};
map[key1] = 1;
map[key2] = 2;

If you were expecting that Object would behave in the same way as a Java Map here, you would be rather miffed to discover that map only contains one entry with the String key [object Object]:

> JSON.stringify(map);
{"[object Object]": 2}

This is clearly not a replacement for Java's HashMap. Bizarrely, given it's age, Javascript does not currently have a general purpose map object. There is hope on the horizon, though: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map although a glance at the Browser Compatability table there will show that this isn't ready to used in general purpose web apps yet.

In the meantime, the best you can do is:

• Deliberately use Strings as keys. I.e. use explicit strings as keys rather than relying on the implicit .toString-ing of the keys you use.
• Ensure that the objects you are using as keys have a well-defined .toString() method that suits your understanding of uniqueness for these objects.
• If you cannot/don't want to change the .toString of the key Objects, when storing and retrieving the entries, convert the objects to a string which represents your understanding of uniqueness. E.g. map[toUniqueString(key1)] = 1

Sometimes, though, that is not possible. If you want to map data based on, for example File objects, there is no reliable way to do this because the attributes that the File object exposes are not enough to ensure its uniqueness. (You may have two File objects that represent different files on disk, but there is no way to distinguish between them in JS in the browser). In these cases, unfortunately, all that you can do is refactor your code to eliminate the need for storing these in a may; perhaps, by using an array instead and referencing them exclusively by index.

If you're using CakePHP 1.3, you can put this in your views to output the SQL:

<?php echo $this->element('sql_dump'); ?>

So you could create a view called 'sql', containing only the line above, and then call this in your controller whenever you want to see it:

$this->render('sql');

(Also remember to set your debug level to at least 2 in app/config/core.php)

Check out the PHP cURL functions. They should do what you want.

Or if you just want a simple URL GET then:

$lines = file('http://www.example.com/');

This will probably have some performance costs when creating the connection but as connections are pooled, they are created only once and then reused, so it won't make any difference to your application. But as always: measure it.

UPDATE:

There are two authentication modes:

1. Windows Authentication mode (corresponding to a trusted connection). Clients need to be members of a domain.
2. SQL Server Authentication mode. Clients are sending username/password at each connection

If you dont want to hard-code the cell addresses you can use the ROW() function.

eg: =AVERAGE(INDIRECT("A" & ROW()), INDIRECT("C" & ROW()))

Its probably not the best way to do it though! Using Auto-Fill and static columns like @JaiGovindani suggests would be much better.

Replace @RunWith(MockitoJUnitRunner.class) with @RunWith(MockitoJUnitRunner.Silent.class).

Not gonna happen with CSS only

Inline javascript

<a href='index.html' 
    onmouseover='this.style.textDecoration="none"' 
    onmouseout='this.style.textDecoration="underline"'>
    Click Me
</a>

In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:

<a href="http://www.w3.org/Style/CSS"
   style="{color: blue; background: white}  /* a+=0 b+=0 c+=0 */
      :visited {color: green}           /* a+=0 b+=1 c+=0 */
      :hover {background: yellow}       /* a+=0 b+=1 c+=0 */
      :visited:hover {color: purple}    /* a+=0 b+=2 c+=0 */
     ">
</a>

but it was never implemented in the release of the spec as far as I know.

http://www.w3.org/TR/2002/WD-css-style-attr-20020515#pseudo-rules

I'm using the following method based on @Watki02's answer:

1. Shift r-click the application to debug
2. Run as different user
3. Attach the debugger to the application

That way you can keep your visual studio instance as your own user whilst debugging from the other.

Spring has an util class for that:

import org.springframework.util.FileCopyUtils;

InputStream is = connection.getInputStream();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
FileCopyUtils.copy(is, bos);
String data = new String(bos.toByteArray());

In very laymen terms the class is a mold and the object is the copy made with that mold. Static belong to the mold and can be accessed directly without making any copies, hence the example above

I can think of one unfortunate side-effect. In java embedded databases, the number of ids you can have with a 32bit id field is 2^31, not 2^32 (~2billion, not ~4billion).

For some of my technical experiments, I was trying to figure out how beneficial and feasible it is to implement bots for different chat platforms in terms of market share and so possibilities of adaptation. Especially when you have bankruptly failed twice, it's important to validate ideas and fail more faster.

Popular chat platforms like Messenger, Slack, Skype etc. have happily (in the sense officially) provided APIs for bots to interact with, but WhatsApp has not yet provided any API.

However, since many years, a lot of activities has happened around this - struggle towards automated interaction with WhatsApp platform:

1. Bots App Bots App is interesting because it shows that something is really tried and tested.

2. Yowsup A project still actively developed to interact with WhatsApp platform.

3. Yallagenie Yallagenie claim that there is a demo bot which can be interacted with at +971 56 112 6652

4. Hubtype Hubtype is working towards having a bot platform for WhatsApp for business.

5. Fred Fred's task was to automate WhatsApp conversations, however since it was not officially supported by WhatsApp - it was shut down.

6. Oye Gennie A bot blocked by WhatsApp.

7. App/Website to WhatsApp We can use custom URL schemes and Android intent system to interact with WhatsApp but still NOT WhatsApp API.

8. Chat API daemon Probably created by inspecting the API calls in WhatsApp web version. NOT affiliated with WhatsApp.

9. WhatsBot Deactivated WhatsApp bot. Created during a hackathon.

10. No API claim WhatsApp co-founder clearly stated this in a conference that they did not had any plans for APIs for WhatsApp.

11. Bot Ware They probably are expecting WhatsApp to release their APIs for chat bot platforms.

12. Vixi They seems to be talking about how some platform which probably would work for WhatsApp. There is no clarity as such.

13. Unofficial API This API can shut off any time.

    And the number goes on...

In one line:

String date=new SimpleDateFormat("MM-dd-yyyy").format(new SimpleDateFormat("yyyy-MM-dd").parse("2011-01-01"));

Where:

String date=new SimpleDateFormat("FinalFormat").format(new SimpleDateFormat("InitialFormat").parse("StringDate"));

Another option is to bind 'View.TrackActivityInSolutionExplorer' to a keyboard short-cut, which is the same as 'Tools-->Options-->Projects and Solutions-->Track Active Item in Solution Explorer'

If you activate the short-cut twice the file is selected in the solution explorer, and the tracking is disabled again.

Visual Studio 2013+

There is now a feature built in to the VS2013 solution explorer called Sync with Active Document. The icon is two arrows in the solution explorer, and has the hotkey Ctrl + [, S to show the current document in the solution explorer. Does not enable the automatic setting mentioned above, and only happens once.

Not with that syntax. But you can do it like this:

git branch -D 3.2 3.2.1 3.2.2

Basically, git branch will delete multiple branch for you with a single invocation. Unfortunately it doesn't do branch name completion. Although, in bash, you can do:

git branch -D `git branch | grep -E '^3\.2\..*'`

Since the encoding that turns "the Family" into "t?? T???ly" is effectively random and not following any algorithm that can be explained by the information of the Unicode codepoints involved, there's no general way to solve this algorithmically.

You will need to build the mapping of Unicode characters into latin characters which they resemble. You could probably do this with some smart machine learning on the actual glyphs representing the Unicode codepoints. But I think the effort for this would be greater than manually building that mapping. Especially if you have a good amount of examples from which you can build your mapping.

To clarify: a few of the substitutions can actually be solved via the Unicode data (as the other answers demonstrate), but some letters simply have no reasonable association with the latin characters which they resemble.

Examples:

• "?" (U+0452 CYRILLIC SMALL LETTER DJE) is more related to "d" than to "h", but is used to represent "h".
• "T" (U+0166 LATIN CAPITAL LETTER T WITH STROKE) is somewhat related to "T" (as the name suggests) but is used to represent "F".
• "?" (U+0E04 THAI CHARACTER KHO KHWAI) is not related to any latin character at all and in your example is used to represent "a"

Try using following command. I haven't tried it but I think it should work.

openssl pkcs8 -topk8 -inform PEM -outform DER -in filename -out filename -nocrypt

Maybe this is what you're looking for?

string = "line #1"\
         "line #2"\
         "line #3"

As mysql official documentation:

Starting with version 6.7, Connector/Net will no longer include the MySQL for Visual Studio integration. That functionality is now available in a separate product called MySQL for Visual Studio available using the MySQL Installer for Windows (see http://dev.mysql.com/tech-resources/articles/mysql-installer-for-windows.html).

log in as root user:

sudo su

password:

then go and do what you want to do in var/www

While you can do

value = d.values()[index]

It should be faster to do

value = next( v for i, v in enumerate(d.itervalues()) if i == index )

edit: I just timed it using a dict of len 100,000,000 checking for the index at the very end, and the 1st/values() version took 169 seconds whereas the 2nd/next() version took 32 seconds.

Also, note that this assumes that your index is not negative

for me DATENAME was not accessable due to company restrictions.... but this worked very easy too.

FORMAT(date, 'MMMM') AS month

If you are doing this just for a parameter coming into a Stored Procedure, you can use the following:

declare @badIndex int
set @badIndex = PatIndex('%[^0-9]%', @Param)
while @badIndex > 0
    set @Param = Replace(@Param, Substring(@Param, @badIndex, 1), '')
    set @badIndex = PatIndex('%[^0-9]%', @Param)

JsonObjectRequest actually accepts JSONObject as body.

From this blog article,

final String url = "some/url";
final JSONObject jsonBody = new JSONObject("{\"type\":\"example\"}");

new JsonObjectRequest(url, jsonBody, new Response.Listener<JSONObject>() { ... });

Here is the source code and JavaDoc (@param jsonRequest):

/**
 * Creates a new request.
 * @param method the HTTP method to use
 * @param url URL to fetch the JSON from
 * @param jsonRequest A {@link JSONObject} to post with the request. Null is allowed and
 *   indicates no parameters will be posted along with request.
 * @param listener Listener to receive the JSON response
 * @param errorListener Error listener, or null to ignore errors.
 */
public JsonObjectRequest(int method, String url, JSONObject jsonRequest,
        Listener<JSONObject> listener, ErrorListener errorListener) {
    super(method, url, (jsonRequest == null) ? null : jsonRequest.toString(), listener,
                errorListener);
}

vim's DirDiff plugin is another very useful tool for comparing directories.

vim -c "DirDiff dir1 dir2"

It not only lists which files are different between the directories, but also allows you to inspect/modify with vimdiff the files that are different.

A fast way to convert strings to an integer is to use a bitwise or, like so:

x | 0

While it depends on how it is implemented, in theory it should be relatively fast (at least as fast as +x) since it will first cast x to a number and then perform a very efficient or.

This might help. No JQuery needed

<a href="../some-relative-link/file" 
onclick="this.href = 'https://docs.google.com/viewer?url='+this.href; this.onclick = '';" 
target="_blank">

This code does the following: Pass the relative link to Google Docs Viewer

1. Get the full link version of the anchor by this.href
2. open the link the the new window.

So in your case this might work:

<a href="../some-relative-link/file" 
onclick="this.href = 'javascript:'+console.log('something has stopped the link'); " 
target="_blank">

In file php.ini you should try this for all errors:

display_errors = On

Location file is:

• Ubuntu 16.04:/etc/php/7.0/apache2
• CentOS 7:/etc/php.ini

Open a terminal and type:

mongo 

The below command should show the listed databases:

show dbs 

/* the <dbname> is the database you'd like to drop */
use <dbname> 

/* the below command will delete the database */
db.dropDatabase()  

The below should be the output in the terminal:

{
  "dropped": "<dbname>",
  "ok": 1
}

Simple:

byte[] data = Convert.FromBase64String(encodedString);
string decodedString = Encoding.UTF8.GetString(data);

Xcode 11

This is the error I got

Provisioning profile "XXX" doesn't include signing certificate "Apple Development: XXX (XXX)".```

Now Xcode 11 automatically created a certificate "Apple Development: XXX" which is valid for all platforms

You just need to

1. Go to https://developer.apple.com
2. Go to your provisioning profile
3. Check if this certificate is selected

if you have long processing server side code, I don't think it does fall into 404 as you said ("it goes to a webpage is not found error page")

Browser should report request timeout error.

You may do 2 things:

Based on CGI/Server side engine increase timeout there

PHP : http://www.php.net/manual/en/info.configuration.php#ini.max-execution-time - default is 30 seconds

In php.ini:

max_execution_time 60

Increase apache timeout - default is 300 (in version 2.4 it is 60).

In your httpd.conf (in server config or vhost config)

TimeOut 600

Note that first setting allows your PHP script to run longer, it will not interferre with network timeout.

Second setting modify maximum amount of time the server will wait for certain events before failing a request

Sorry, I'm not sure if you are using PHP as server side processing, but if you provide more info I will be more accurate.

Jon's disassemblies show, that the difference between the two versions is that the fast version uses a pair of registers (esi,edi) to store one of the local variables where the slow version doesn't.

The JIT compiler makes different assumptions regarding register use for code that contains a try-catch block vs. code which doesn't. This causes it to make different register allocation choices. In this case, this favors the code with the try-catch block. Different code may lead to the opposite effect, so I would not count this as a general-purpose speed-up technique.

In the end, it's very hard to tell which code will end up running the fastest. Something like register allocation and the factors that influence it are such low-level implementation details that I don't see how any specific technique could reliably produce faster code.

For example, consider the following two methods. They were adapted from a real-life example:

interface IIndexed { int this[int index] { get; set; } }
struct StructArray : IIndexed { 
    public int[] Array;
    public int this[int index] {
        get { return Array[index]; }
        set { Array[index] = value; }
    }
}

static int Generic<T>(int length, T a, T b) where T : IIndexed {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}
static int Specialized(int length, StructArray a, StructArray b) {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}

One is a generic version of the other. Replacing the generic type with StructArray would make the methods identical. Because StructArray is a value type, it gets its own compiled version of the generic method. Yet the actual running time is significantly longer than the specialized method's, but only for x86. For x64, the timings are pretty much identical. In other cases, I've observed differences for x64 as well.

CSS Styles are key-value pairs, not just "tags". By default, each element has a full set of CSS styles assigned to it, most of them is implicitly using the browser defaults and some of them is explicitly redefined in CSS stylesheets.

To get the value assigned to a particular CSS entry of an element and compare it:

if ($('#yourElement').css('position') == 'absolute')
{
   // true
}

If you didn't redefine the style, you will get the browser default for that particular element.

If you are allowed to go further then javascript/html facilities - I would use the apache web server to represent your directory listing via http.

If this solution is appropriate. these are the steps:

1. download apache hhtp server from one of the mirrors http://httpd.apache.org/download.cgi

2. unzip/install (if msi) it to the directory e.g C:\opt\Apache (the instruction is for windows)

3. map the network forlder as a local drive on windows (\server\folder to let's say drive H:)

4. open conf/httpd.conf file

5. make sure the next line is present and not commented

   LoadModule autoindex_module modules/mod_autoindex.so

6. Add directory configuration

<Directory "H:/path">

Options +Indexes

AllowOverride None

Order allow,deny

Allow from all

</Directory> 7. Start the web server and make sure the directory listingof the remote folder is available by http. hit localhost/path 8. use a frame inside your web page to access the listing

What is missed: 1. you mignt need more fancy configuration for the host name, refer to Apache Web Server docs. Register the host name in DNS server

1. the mapping to the network drive might not work, i did not check. As a posible resolution - host your web server on the same machine as smb server.

Maintain aspect Ration and eliminate letterbox and Pillarbox.

        nPercentW = ((float)Width / (float)sourceWidth);
        nPercentH = ((float)Height / (float)sourceHeight);
        if (nPercentH < nPercentW)

        }
        else
        {
            nPercent = nPercentW;
        }

        int destWidth = (int)(sourceWidth * nPercent);
        int destHeight = (int)(sourceHeight * nPercent);

        Bitmap bmPhoto = new Bitmap(destWidth, destHeight, PixelFormat.Format24bppRgb);

        bmPhoto.SetResolution(imgPhoto.HorizontalResolution,
                                         imgPhoto.VerticalResolution);

        Graphics grPhoto = Graphics.FromImage(bmPhoto);

        grPhoto.DrawImage(imgPhoto,
                new Rectangle(X, Y, destWidth, destHeight),
                new Rectangle(X, Y, sourceWidth, sourceHeight),
                GraphicsUnit.Pixel);

        grPhoto.Dispose();
        return bmPhoto;
    }

An example with a little less stringified html:

var container = $('#my-container'),
  table = $('<table>');

users.forEach(function(user) {
  var tr = $('<tr>');
  ['ID', 'Name', 'Address'].forEach(function(attr) {
    tr.append('<td>' + user[attr] + '</td>');
  });
  table.append(tr);
});

container.append(table);

I have PHP 5.3.1 and Apache

When I add the extension=php_intl.dll to php.ini and restart apache, it comes an alert that says "the requested operation has failed"

And this error on Event Monitor:

Faulting application name: httpd.exe, version: 2.2.14.0, time stamp: 0x4ac181d6
Faulting module name: php5ts.dll, version: 5.3.1.0, time stamp: 0x4b051b35
Exception code: 0xc0000005

The problem was some DLLs like icudt36.dll were missing (noticed with sysinternals ProcMon), I've downloaded php 5.3.1 zip version and extract all DLL's to PHP folder. That solved the problem.

var x = 0;
var y = 0;

function getMouseY() {

}

There is no such thing like a DateTime without a year!

From what I gather your design is a bit strange:

I would recommend storing a "start" (DateTime including year for the FIRST occurence) and a value which designates how to calculate the next event... this could be for example a TimeSpan or some custom structure esp. since "every year" can mean that the event occurs on a specific date and would not automatically be the same as saysing that it occurs in +365 days.

After the event occurs you calculate the next and store that etc.

All other answers posted here are only working with public attributes. Here is one solution that works with JavaBeans-like objects using reflection and getters:

function entity2array($entity, $recursionDepth = 2) {
    $result = array();
    $class = new ReflectionClass(get_class($entity));
    foreach ($class->getMethods(ReflectionMethod::IS_PUBLIC) as $method) {
        $methodName = $method->name;
        if (strpos($methodName, "get") === 0 && strlen($methodName) > 3) {
            $propertyName = lcfirst(substr($methodName, 3));
            $value = $method->invoke($entity);

            if (is_object($value)) {
                if ($recursionDepth > 0) {
                    $result[$propertyName] = $this->entity2array($value, $recursionDepth - 1);
                }
                else {
                    $result[$propertyName] = "***";  // Stop recursion
                }
            }
            else {
                $result[$propertyName] = $value;
            }
        }
    }
    return $result;
}

There is no inherent limit. The maximum number of threads is determined by the amount of physical resources available. See this article by Raymond Chen for specifics.

If you need to ask what the maximum number of threads is, you are probably doing something wrong.

[Update: Just out of interest: .NET Thread Pool default numbers of threads:

• 1023 in Framework 4.0 (32-bit environment)
• 32767 in Framework 4.0 (64-bit environment)
• 250 per core in Framework 3.5
• 25 per core in Framework 2.0

The original accepted answer mentions jquery.cookie plugin. A few months ago though, it was renamed to js-cookie and the jQuery dependency removed. One of the reasons was just to make it easy to integrate with other frameworks, like Angular.

Now, if you want to integrate js-cookie with angular, it is as easy as something like:

module.factory( "cookies", function() {
  return Cookies.noConflict();
});

And that's it. No jQuery. No ngCookies.

You can also create custom instances to handle specific server-side cookies that are written differently. Take for example PHP, that convert the spaces in the server-side to a plus sign + instead of also percent-encode it:

module.factory( "phpCookies", function() {
  return Cookies
    .noConflict()
    .withConverter(function( value, name ) {
      return value
            // Decode all characters according to the "encodeURIComponent" spec
            .replace(/(%[0-9A-Z]{2})+/g, decodeURIComponent)
            // Decode the plus sign to spaces
            .replace(/\+/g, ' ')
    });
});

The usage for a custom Provider would be something like this:

module.service( "customDataStore", [ "phpCookies", function( phpCookies ) {
  this.storeData = function( data ) {
    phpCookies.set( "data", data );
  };
  this.containsStoredData = function() {
    return phpCookies.get( "data" );
  }
}]);

I hope this helps anyone.

See detailed info in this issue: https://github.com/js-cookie/js-cookie/issues/103

For detailed docs on how to integrate with server-side, see here: https://github.com/js-cookie/js-cookie/blob/master/SERVER_SIDE.md

The proposed solutions are perfect to download the images and if it is enough for you to save all the files in the directory you are using. But if you want to save all the images in a specified directory without reproducing the entire hierarchical tree of the site, try to add "cut-dirs" to the line proposed by Jon.

wget -r -P /save/location -A jpeg,jpg,bmp,gif,png http://www.boia.de --cut-dirs=1 --cut-dirs=2 --cut-dirs=3

in this case cut-dirs will prevent wget from creating sub-directories until the 3th level of depth in the website hierarchical tree, saving all the files in the directory you specified.You can add more 'cut-dirs' with higher numbers if you are dealing with sites with a deep structure.

Add Docker’s official GPG key:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Then install

$ sudo apt-get update && sudo apt-get -y install docker-ce

I solved a problem to comparing a integer Column x a varchar column with

where CAST(Column_name AS CHAR CHARACTER SET latin1 ) collate latin1_general_ci = varchar_column_name

I faced the same problem.
I was running It as CLI. So PHP was always running and it had to make soap call again and again after some interval.
The mistake I did was using singleton pattern for this. I thought use of singleton will cause performance boost but inturn I got

Error Fetching http headers in ...

I fixed it by creating new saop object for each call.

There is many ways to use it and i recomend you to see this documentation about String Format.

http://developer.android.com/intl/pt-br/reference/java/util/Formatter.html

But, if you need only one variable, you'll need to use %[type] where [type] could be any Flag (see Flag types inside site above). (i.e. "My name is %s" or to set my name UPPERCASE, use this "My name is %S")

<string name="welcome_messages">Hello, %1$S! You have %2$d new message(s) and your quote is %3$.2f%%.</string>

Hello, ANDROID! You have 1 new message(s) and your quote is 80,50%.

While I realize this is an older thread, I noticed the if block above is out of place with using:

Following is corrected:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim filePath As String =
      String.Format("C:\ErrorLog_{0}.txt", DateTime.Today.ToString("dd-MMM-yyyy"))
    Using writer As New StreamWriter(filePath, True)
        If File.Exists(filePath) Then
            writer.WriteLine("Error Message in  Occured at-- " & DateTime.Now)
        Else
            writer.WriteLine("Start Error Log for today")
        End If
    End Using
End Sub

Try this. It is working and tested.

for k in "${array[@]}"
do
    echo $k
done

# For accessing with the echo command: echo ${array[0]}, ${array[1]}

You may use the padding and margin shorthand Bootstrap 4 classes as follows:

For extra small devices i.e. xs

{property}{sides}-{size}

For other devices/viewports (small, medium, large and extra large)

{property}{sides}-{breakpoint}-{size}

Where:

property = m for margin and p for padding

Following are sides shorthand meanings:

l = defines the left-margin or left-padding
r = defines the right-margin or right-padding
t = defines the top-margin or top-padding
b = defines the bottom-margin or right-padding
x = For setting left and right padding and margins by the single call
y = For setting top and bottom margins
blank = margin and padding for all sides

The breakpoint = sm, md, lg, and xl.

Combining all the above, the left padding complete code can be (for example):

For left padding in extra small devices

pl-2

or for medium to extra large

pl-md-2

I had this error. Nothing worked for me until I opened the SQLServer log file in the "MSSQL10_50" Log folder. That clearly stated which file could not be overwritten. It turned out that the .mdf file was being written into the "MSSQL10" data folder. I made sure that folder had the same SQLServer user permissions as the "MSSQL10_50" equivalent folder. Then it all worked.

The issue here is that the error detail is logged but not reported, so check the logs.

It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!

The only times you should need to escape are when trying to put " inside a string, or ' in a character:

String quotes = "He said \"Hello, World!\"";
char quote = '\'';

<div class="container">_x000D_
    <div class="row">_x000D_
        <div class="col d-flex justify-content-center">_x000D_
             CenterContent_x000D_
        </div>_x000D_
    </div>_x000D_
</div>

Enable 'flex' for the column as we want & use justify-content-center

Use

fmt.Println(t.Format("20060102150405"))

as Go uses following constants to format date,refer here

const (
    stdLongMonth      = "January"
    stdMonth          = "Jan"
    stdNumMonth       = "1"
    stdZeroMonth      = "01"
    stdLongWeekDay    = "Monday"
    stdWeekDay        = "Mon"
    stdDay            = "2"
    stdUnderDay       = "_2"
    stdZeroDay        = "02"
    stdHour           = "15"
    stdHour12         = "3"

I known this isn't markdown, but <p align="center"> worked for me, so if anyone figures out the markdown syntax instead I'll be happy to use that. Until then I'll use the HTML tag.

I like to accept a form post for my POST actions, even if I don't need it. For me it just feels like the right thing to do as you're supposedly posting something.

public class HomeController : Controller
{
    public ActionResult Index()
    {
        //Code...
        return View();
    }

    [HttpPost]
    public ActionResult Index(FormCollection form)
    {
        //Code...
        return View();
    }
}

You can use the annotate command to place text annotations at any x and y values you want. To place them exactly at the data points you could do this

import numpy
from matplotlib import pyplot

x = numpy.arange(10)
y = numpy.array([5,3,4,2,7,5,4,6,3,2])

fig = pyplot.figure()
ax = fig.add_subplot(111)
ax.set_ylim(0,10)
pyplot.plot(x,y)
for i,j in zip(x,y):
    ax.annotate(str(j),xy=(i,j))

pyplot.show()

If you want the annotations offset a little, you could change the annotate line to something like

ax.annotate(str(j),xy=(i,j+0.5))

Use svcutil.exe with the /sc switch to generate the WCF contracts. This will create a code file that you can add to your project. It will contain all interfaces and data types you need to create your service. Change the output location using the /o switch, or you can find the file in the folder where you ran svcutil.exe. The default language is C# but I think (I've never tried it) you should be able to change this using /l:vb.

svcutil /sc "WSDL file path"

If your WSDL has any supporting XSD files pass those in as arguments after the WSDL.

svcutil /sc "WSDL file path" "XSD 1 file path" "XSD 2 file path" ... "XSD n file path"

Then create a new class that is your service and implement the contract interface you just created.

You have three options:

• Use another way to get the file on the server, and use a mysql client on the server
• Use another client to connect to the server and load the data
• Change your PHP settings to allow such huge files. Don't forget to increment the execution time as well.

Had a problem in Angular2, I was using the local storage to save something and it would not let me.

Solutions:

I had localStorage.city -> error -> Property 'city' does not exist on type 'Storage'.

How to fix it:

localStorage['city']

(localStorage).city

(localStorage as any).city

Ryan Bates uses a nice little bit of code in his Railscast on beta invitations. This produces a 40 character alphanumeric string.

Digest::SHA1.hexdigest([Time.now, rand].join)

I agree with Cade Roux.

This article should get you on the right track:

• Indexes in SQL Server 2005/2008 – Best Practices, Part 1
• Indexes in SQL Server 2005/2008 – Part 2 – Internals

One thing to note, clustered indexes should have a unique key (an identity column I would recommend) as the first column. Basically it helps your data insert at the end of the index and not cause lots of disk IO and Page splits.

Secondly, if you are creating other indexes on your data and they are constructed cleverly they will be reused.

e.g. imagine you search a table on three columns

state, county, zip.

• you sometimes search by state only.
• you sometimes search by state and county.
• you frequently search by state, county, zip.

Then an index with state, county, zip. will be used in all three of these searches.

If you search by zip alone quite a lot then the above index will not be used (by SQL Server anyway) as zip is the third part of that index and the query optimiser will not see that index as helpful.

You could then create an index on Zip alone that would be used in this instance.

By the way We can take advantage of the fact that with Multi-Column indexing the first index column is always usable for searching and when you search only by 'state' it is efficient but yet not as efficient as Single-Column index on 'state'

I guess the answer you are looking for is that it depends on your where clauses of your frequently used queries and also your group by's.

The article will help a lot. :-)

If you want to import the promise based version of fs as an ES module you can do:

import { promises as fs } from 'fs'

await fs.writeFile(...)

As soon as node v14 is released (see this PR), you can also use

import { writeFile } from 'fs/promises'

My Solution is given below here searchDetail is an object..

<p-calendar  [ngModel]="searchDetail.queryDate | date:'MM/dd/yyyy'"  (ngModelChange)="searchDetail.queryDate=$event" [showIcon]="true" required name="queryDate" placeholder="Enter the Query Date"></p-calendar>

<input id="float-input" type="text" size="30" pInputText [ngModel]="searchDetail.systems | json"  (ngModelChange)="searchDetail.systems=$event" required='true' name="systems"
            placeholder="Enter the Systems">

The algorithm you are using, "AES", is a shorthand for "AES/ECB/NoPadding". What this means is that you are using the AES algorithm with 128-bit key size and block size, with the ECB mode of operation and no padding.

In other words: you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception.

If you want to encrypt data in sizes that are not multiple of 16 bytes, you are either going to have to use some kind of padding, or a cipher-stream. For instance, you could use CBC mode (a mode of operation that effectively transforms a block cipher into a stream cipher) by specifying "AES/CBC/NoPadding" as the algorithm, or PKCS5 padding by specifying "AES/ECB/PKCS5", which will automatically add some bytes at the end of your data in a very specific format to make the size of the ciphertext multiple of 16 bytes, and in a way that the decryption algorithm will understand that it has to ignore some data.

In any case, I strongly suggest that you stop right now what you are doing and go study some very introductory material on cryptography. For instance, check Crypto I on Coursera. You should understand very well the implications of choosing one mode or another, what are their strengths and, most importantly, their weaknesses. Without this knowledge, it is very easy to build systems which are very easy to break.

Update: based on your comments on the question, don't ever encrypt passwords when storing them at a database!!!!! You should never, ever do this. You must HASH the passwords, properly salted, which is completely different from encrypting. Really, please, don't do what you are trying to do... By encrypting the passwords, they can be decrypted. What this means is that you, as the database manager and who knows the secret key, you will be able to read every password stored in your database. Either you knew this and are doing something very, very bad, or you didn't know this, and should get shocked and stop it.

I had a similar problem.

I wanted to set the state of where the 2nd level key was stored in a variable.

e.g. this.setState({permissions[perm.code]: e.target.checked})

However this isn't valid syntax.

I used the following code to achieve this:

this.setState({
  permissions: {
    ...this.state.permissions,
    [perm.code]: e.target.checked
  }
});

One easy way is to drag and drop. It will copy files to /sdcard/Download. You can copy whole folders or multiple files. Make sure that "Enable Clipboard Sharing" is enabled. (under ...->Settings)

You can check the total number of arguments which are passed in command line with "$#" Say for Example my shell script name is hello.sh

sh hello.sh hello-world
# I am passing hello-world as argument in command line which will b considered as 1 argument 
if [ $# -eq 1 ] 
then
    echo $1
else
    echo "invalid argument please pass only one argument "
fi

Output will be hello-world

To use base_url() (shorthand), you have to load the URL Helper first

$this->load->helper('url');

Or you can autoload it by changing application/config/autoload.php

Or just use

$this->config->base_url();

Same applies to site_url().

Also I can see you are missing echo (though its not your current problem), use the code below to solve the problem

<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />

Below command used to export collection to CSV format.

Note: naag is database, employee1_json is a collection.

mongoexport --db naag--collection employee1_json --type csv --out /home/orienit/work/mongodb/employee1_csv_op1

You have it backwards. Display the calendar first, and then call gotoDate.

$('#calendar').fullCalendar({
  // Options
});

$('#calendar').fullCalendar('gotoDate', currentDate);

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

Hello this is a snippet from an old project of mine that uses curl to get ip information from some free ip databases services which reply in json format. I think it might help you.

$ip_srv = array("http://freegeoip.net/json/$this->ip","http://smart-ip.net/geoip-json/$this->ip");

getUserLocation($ip_srv);

Function:

function getUserLocation($services) {

        $ctx = stream_context_create(array('http' => array('timeout' => 15))); // 15 seconds timeout

        for ($i = 0; $i < count($services); $i++) {

            // Configuring curl options
            $options = array (
                CURLOPT_RETURNTRANSFER => true, // return web page
                //CURLOPT_HEADER => false, // don't return headers
                CURLOPT_HTTPHEADER => array('Content-type: application/json'),
                CURLOPT_FOLLOWLOCATION => true, // follow redirects
                CURLOPT_ENCODING => "", // handle compressed
                CURLOPT_USERAGENT => "test", // who am i
                CURLOPT_AUTOREFERER => true, // set referer on redirect
                CURLOPT_CONNECTTIMEOUT => 5, // timeout on connect
                CURLOPT_TIMEOUT => 5, // timeout on response
                CURLOPT_MAXREDIRS => 10 // stop after 10 redirects
            ); 

            // Initializing curl
            $ch = curl_init($services[$i]);
            curl_setopt_array ( $ch, $options );

            $content = curl_exec ( $ch );
            $err = curl_errno ( $ch );
            $errmsg = curl_error ( $ch );
            $header = curl_getinfo ( $ch );
            $httpCode = curl_getinfo ( $ch, CURLINFO_HTTP_CODE );

            curl_close ( $ch );

            //echo 'service: ' . $services[$i] . '</br>';
            //echo 'err: '.$err.'</br>';
            //echo 'errmsg: '.$errmsg.'</br>';
            //echo 'httpCode: '.$httpCode.'</br>';
            //print_r($header);
            //print_r(json_decode($content, true));

            if ($err == 0 && $httpCode == 200 && $header['download_content_length'] > 0) {

                return json_decode($content, true);

            } 

        }
    }

I'd like to propose

np.min(np.append(np.where(aa>5)[0],np.inf))

This will return the smallest index where the condition is met, while returning infinity if the condition is never met (and where returns an empty array).

This is for dynamic # of weeks.

Full example here:SQL Dynamic Pivot

DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)

--Get distinct values of the PIVOT Column 
SELECT @ColumnName= ISNULL(@ColumnName + ',','') + QUOTENAME(Week)
FROM (SELECT DISTINCT Week FROM #StoreSales) AS Weeks

--Prepare the PIVOT query using the dynamic 
SET @DynamicPivotQuery = 
  N'SELECT Store, ' + @ColumnName + ' 
    FROM #StoreSales
    PIVOT(SUM(xCount) 
          FOR Week IN (' + @ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query
EXEC sp_executesql @DynamicPivotQuery

Another variation

.blink {_x000D_
    -webkit-animation: blink 1s step-end infinite;_x000D_
            animation: blink 1s step-end infinite;_x000D_
}_x000D_
@-webkit-keyframes blink { 50% { visibility: hidden; }}_x000D_
        @keyframes blink { 50% { visibility: hidden; }}

This is <span class="blink">blink</span>

Refer to example 2 for 'Type' class understanding of Gson.

Example 1: In this deserilizeResturant we used Employee[] array and get the details

public static void deserializeResturant(){

       String empList ="[{\"name\":\"Ram\",\"empId\":1},{\"name\":\"Surya\",\"empId\":2},{\"name\":\"Prasants\",\"empId\":3}]";
       Gson gson = new Gson();
       Employee[] emp = gson.fromJson(empList, Employee[].class);
       int numberOfElementInJson = emp.length();
       System.out.println("Total JSON Elements" + numberOfElementInJson);
       for(Employee e: emp){
           System.out.println(e.getName());
           System.out.println(e.getEmpId());
       }
   }

Example 2:

//Above deserilizeResturant used Employee[] array but what if we need to use List<Employee>
public static void deserializeResturantUsingList(){

    String empList ="[{\"name\":\"Ram\",\"empId\":1},{\"name\":\"Surya\",\"empId\":2},{\"name\":\"Prasants\",\"empId\":3}]";
    Gson gson = new Gson();

    // Additionally we need to se the Type then only it accepts List<Employee> which we sent here empTypeList
    Type empTypeList = new TypeToken<ArrayList<Employee>>(){}.getType();


    List<Employee> emp = gson.fromJson(empList, empTypeList);
    int numberOfElementInJson = emp.size();
    System.out.println("Total JSON Elements" + numberOfElementInJson);
    for(Employee e: emp){
        System.out.println(e.getName());
        System.out.println(e.getEmpId());
    }
}

Note the official docs on connection configuration variables or "behavioral" variables - which aren't listed in host vars, appears to be List of Behavioral Inventory Parameters in the Inventory documentation.

P.S. The sudo option is undocumented there (yes its sudo not ansible_sudo as you'd expect ...) and probably a couple more aren't, but thats best doc I've found on em.

Given that you wish to wait for the print dialog to go away I would use focus binding on the window.

print();

var handler = function(){
    //unbind task();
    $(window).unbind("focus",handler);
}

$(window).bind("focus",handler);

By putting in the unbind in the handler function we prevent the focus event staying bond to the window.

However, interface is 100% abstract class and abstract class can implements interface(100% abstract class) without implement its methods. What is the problem when it is defining as "interface" ?

This is simply a matter of convention. The writers of the java language decided that "extends" is the best way to describe this relationship, so that's what we all use.

In general, even though an interface is "a 100% abstract class," we don't think about them that way. We usually think about interfaces as a promise to implement certain key methods rather than a class to derive from. And so we tend to use different language for interfaces than for classes.

As others state, there are good reasons for choosing "extends" over "implements."

Using kramdown, it seems like this works well:

[I want this to link to foo](#foo)
....
....
{: id="foo"}
### Foo are you?

I see it's been mentioned that

[foo][#foo]
....
#Foo

works efficiently, but the former might be a good alternative for elements besides headers or else headers with multiple words.

Use This Code

@echo off
:: Get the current directory

for /f "tokens=* delims=/" %%A in ('cd') do set CURRENT_DIR=%%A

echo CURRENT_DIR%%A 

(echo this To confirm this code works fine)

Add /usr/local/bin to your PATH environment variable, earlier in the list than /usr/bin.

Generally this is done in your shell's rc file, e.g. for bash, you'd put this in .bashrc:

export PATH="/usr/local/bin:$PATH"

This will cause your shell to look first for a python in /usr/local/bin, before it goes with the one in /usr/bin.

(Of course, this means you also need to have /usr/local/bin/python point to python2.7 - if it doesn't already, you'll need to symlink it.)

Does not work for multidimensional arrays, because references are used here.

import numpy as np

# swaps
data = np.random.random(2)
print(data)
data[0], data[1] = data[1], data[0]
print(data)

# does not swap
data = np.random.random((2, 2))
print(data)
data[0], data[1] = data[1], data[0]
print(data)

See also Swap slices of Numpy arrays

After a lot of trial and error i actually find the best, clearest and easiest multidimensional array on bash is to use a regular var. Yep.

Advantages: You don't have to loop through a big array, you can just echo "$var" and use grep/awk/sed. It's easy and clear and you can have as many columns as you like.

Example:

$ var=$(echo -e 'kris hansen oslo\nthomas jonson peru\nbibi abu johnsonville\njohnny lipp peru')

$ echo "$var"
kris hansen oslo
thomas johnson peru
bibi abu johnsonville
johnny lipp peru

If you want to find everyone in peru

$ echo "$var" | grep peru
thomas johnson peru
johnny lipp peru

Only grep(sed) in the third field

$ echo "$var" | sed -n -E '/(.+) (.+) peru/p'
thomas johnson peru
johnny lipp peru

If you only want x field

$ echo "$var" | awk '{print $2}'
hansen
johnson
abu
johnny

Everyone in peru that's called thomas and just return his lastname

$ echo "$var" |grep peru|grep thomas|awk '{print $2}'
johnson

Any query you can think of... supereasy.

To change an item:

$ var=$(echo "$var"|sed "s/thomas/pete/")

To delete a row that contains "x"

$ var=$(echo "$var"|sed "/thomas/d")

To change another field in the same row based on a value from another item

Of course looping works too if you want to do that

$ for i in "$var"; do echo "$i"; done

The only gotcha iv'e found with this is that you must always quote the var(in the example; both var and i) or things will look like this

$ for i in "$var"; do echo $i; done

and someone will undoubtedly say it won't work if you have spaces in your input, however that can be fixed by using another delimeter in your input, eg(using an utf8 char now to emphasize that you can choose something your input won't contain, but you can choose whatever ofc):

$ var=$(echo -e 'field one?field two hello?field three yes moin\nfield 1?field 2?field 3 dsdds aq')

$ for i in "$var"; do echo "$i"; done
field one?field two hello?field three yes moin
field 1?field 2?field 3 dsdds aq

$ echo "$var" | awk -F '?' '{print $3}'
field three yes moin
field 3 dsdds aq

$ var=$(echo "$var"|sed -E "s/(field one)?(.+)?(.+)/\1?test?\3/")
$ echo "$var"
field one?test?field three yes moin
field 1?field 2?field 3 dsdds aq

If you want to store newlines in your input, you could convert the newline to something else before input and convert it back again on output(or don't use bash...). Enjoy!

I also tried to benchmark the different kinds of loop in C#. I used the same code as Shane, but I also tried with a do-while and found it to be the fastest. This is the code:

using System;
using System.Diagnostics;


public class Program
{
    public static void Main()
    {
        int max = 9999999;
        Stopwatch stopWatch = new Stopwatch();

        Console.WriteLine("Do While Loop: ");
        stopWatch.Start();
        DoWhileLoop(max);
        stopWatch.Stop();
        DisplayElapsedTime(stopWatch.Elapsed);
        Console.WriteLine("");
        Console.WriteLine("");

        Console.WriteLine("While Loop: ");
        stopWatch.Start();
        WhileLoop(max);
        stopWatch.Stop();
        DisplayElapsedTime(stopWatch.Elapsed);
        Console.WriteLine("");
        Console.WriteLine("");

        Console.WriteLine("For Loop: ");
        stopWatch.Start();
        ForLoop(max);
        stopWatch.Stop();
        DisplayElapsedTime(stopWatch.Elapsed);
    }

    private static void DoWhileLoop(int max)
    {
        int i = 0;
        do
        {
            //Performe Some Operation. By removing Speed increases
            var j = 10 + 10;
            j += 25;
            i++;
        } while (i <= max);
    }

    private static void WhileLoop(int max)
    {
        int i = 0;
        while (i <= max)
        {
            //Performe Some Operation. By removing Speed increases
            var j = 10 + 10;
            j += 25;
            i++;
        };
    }

    private static void ForLoop(int max)
    {
        for (int i = 0; i <= max; i++)
        {
            //Performe Some Operation. By removing Speed increases
            var j = 10 + 10;
            j += 25;
        }
    }

    private static void DisplayElapsedTime(TimeSpan ts)
    {
        string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds / 10);
        Console.WriteLine(elapsedTime, "RunTime");
    }
}

and these are the results of a live demo on DotNetFiddle:

Do While Loop:
00:00:00.06

While Loop:
00:00:00.13

For Loop:
00:00:00.27

I think this is the simplest alias, add to your ~/.gitconfig

[alias]
  publish-branch = !git push -u origin $(git rev-parse --abbrev-ref HEAD)

You just run

git publish-branch

and... it publishes the branch

I think this would serve as a simpler example of what you want to achieve. There is no need to use external tools. Bash built in tools can do the job for you.

function DOSOMETHING {

   while test $# -gt 0; do
           case "$1" in
                -first)
                    shift
                    first_argument=$1
                    shift
                    ;;
                -last)
                    shift
                    last_argument=$1
                    shift
                    ;;
                *)
                   echo "$1 is not a recognized flag!"
                   return 1;
                   ;;
          esac
  done  

  echo "First argument : $first_argument";
  echo "Last argument : $last_argument";
 }

This will allow you to use flags so no matter which order you are passing the parameters you will get the proper behavior.

Example :

 DOSOMETHING -last "Adios" -first "Hola"

Output :

 First argument : Hola
 Last argument : Adios

You can add this function to your profile or put it inside of a script.

Thanks!

Edit : Save this as a a file and then execute it as yourfile.sh -last "Adios" -first "Hola"

#!/bin/bash
while test $# -gt 0; do
           case "$1" in
                -first)
                    shift
                    first_argument=$1
                    shift
                    ;;
                -last)
                    shift
                    last_argument=$1
                    shift
                    ;;
                *)
                   echo "$1 is not a recognized flag!"
                   return 1;
                   ;;
          esac
  done  

  echo "First argument : $first_argument";
  echo "Last argument : $last_argument";

In a Groovy script the scoping can be different than expected. That is because a Groovy script in itself is a class with a method that will run the code, but that is all done runtime. We can define a variable to be scoped to the script by either omitting the type definition or in Groovy 1.8 we can add the @Field annotation.

import groovy.transform.Field

var1 = 'var1'
@Field String var2 = 'var2'
def var3 = 'var3'

void printVars() {
    println var1
    println var2
    println var3 // This won't work, because not in script scope.
}

First of all this code snippet

char *addr=NULL;
strcpy(addr,retstring().c_str());

is invalid because you did not allocate memory where you are going to copy retstring().c_str().

As for the error message then it is clear enough. The type of expression data.str().c_str() is const char * but the third parameter of the function is declared as char *. You may not assign an object of type const char * to an object of type char *. Either the function should define the third parameter as const char * if it does not change the object pointed by the third parameter or you may not pass argument of type const char *.

Much Easier approach.

Just include dependency in your app level gradle file

compile 'com.journeyapps:zxing-android-embedded:3.0.1@aar'
compile 'com.google.zxing:core:3.2.0'  

Define one button in your xml file and and write below code in Java file in OnCreate()and inside the OnClick listener of button

new IntentIntegrator(this).initiateScan();

And write below code after OnCreate() of the Java file

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
    if(result != null) {
        if(result.getContents() == null) {
            Log.d("MainActivity", "Cancelled scan");
            Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
        } else {
            Log.d("MainActivity", "Scanned");
            String st_scanned_result = result.getContents();
            Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();

        }
    }

}

For example 8/12/1976. Copy your date column. Highlight the copied column and click Data> Text to Columns> Delimited> Next. In the delimiters column check "Other" and input / and then click Next and Finish. You'll have 3 columns and the first column will be 1/8. Highlight it and click the comma in the Number section and it will give you the month as 8.00, so then reduce it by clicking the comma in Home/Numbers and you'll now have 8 in the first column, 18 in the second column and 1976 in the third column. In the first empty cell to the right use the concatenate function and leave out the year column. If your month is column A, day is column B and year is column C, it will look like this: =concatenate(A2,"/",B2) and hit enter. It will look like 8/18, however, when you click on the cell you'll see the concatenate formula. Highlight the cell(s), then copy and paste special values. Now you can sort by date. It's really quick when you get the hang of it.

According to this post, it's much better now:

// pick out one album
JObject jalbum = albums[0] as JObject;

// Copy to a static Album instance
Album album = jalbum.ToObject<Album>();

Documentation: Convert JSON to a Type

let us have two number B and C , encoding them into single number A

A = B + C * N

where

B=A % N = B

C=A / N = C

Use .height() like this:

var result = $("#myDiv").height();

There's also .innerHeight() and .outerHeight() depending on exactly what you want.

You can test it here, play with the padding/margins/content to see how it changes around.

You can use a drawable. Create a drawable layout file in your drawable folder. Paste this code. You can as well modify it - border.xml.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
    android:width="1dp"
    android:color="@color/divider" />
<solid
    android:color="#00FFFFFF"
    android:paddingLeft="10dp"
    android:paddingTop="10dp"/>
<padding
    android:left="10dp"
    android:top="10dp"
    android:right="10dp"
    android:bottom="10dp" />
</shape>

in your EditText view, add

android:background="@drawable/border"

It can even be made dependent to another attribute changes. like this:

$('.classA').toggleClass('classB', $('input').prop('disabled'));

In this case, classB are added each time the input is disabled

Dot notation will break the type checking, switch to bracket notation. You might also try using the get() method. It also keeps AOT compilation in tact I've read.

this.form.get('controlName').value // safer
this.form.controlName.value // triggers type checking and breaks AOT

Your code is reading a sequence of UTF8-encoded bytes, and decoding them using an 8-bit encoding.

You need to fix that code to decode the bytes as UTF8.

Alternatively (not ideal), you could convert the bad string back to the original byte array—by encoding it using the incorrect encoding—then re-decode the bytes as UTF8.

Updated with swift 4

override func viewDidLoad() {
    super.viewDidLoad()
        self.navigationController?.navigationBar.tintColor = UIColor.blue
        self.navigationController?.navigationBar.barStyle = UIBarStyle.black
}

    function ArrayToObject( arr ) {
    var obj = {};
    for (var i = 0; i < arr.length; ++i){
        var name = arr[i].name;
        var value = arr[i].value;
        obj[name] = arr[i].value;
    }
    return obj;
    }

      var form_data = $('#my_form').serializeArray();
            form_data = ArrayToObject( form_data );
            form_data.action = event.target.id;
            form_data.target = event.target.dataset.event;
            console.log( form_data );
            $.post("/api/v1/control/", form_data, function( response ){
                console.log(response);
            }).done(function( response ) {
                $('#message_box').html('SUCCESS');
            })
            .fail(function(  ) { $('#message_box').html('FAIL'); })
            .always(function(  ) { /*$('#message_box').html('SUCCESS');*/ });

Using "fill" attribute helps in cases like this. You can remove the text from axis using element_blank()and show multi color bar chart with a legend. I am plotting a part removal frequency in a repair shop as below

ggplot(data=df_subset,aes(x=Part,y=Removal_Frequency,fill=Part))+geom_bar(stat="identity")+theme(axis.text.x  = element_blank())

I went for this solution in my case as I had many bars in bar chart and I was not able to find a suitable font size which is both readable and also small enough not to overlap each other.

In general, if you are using white-space: nowrap; it is probably because you know which columns are going to contain content which wraps (or stretches the cell). For those columns, I generally wrap the cell's contents in a span with a specific class attribute and apply a specific width.

Example:

HTML:

<td><span class="description">My really long description</span></td>

CSS:

span.description {
    display: inline-block;
    overflow: hidden;
    white-space: nowrap;
    width: 150px;
}

You can use console.dir(object) to write that objects properties to the console.

I needed this too, and the links above stopped working so this is what I found to work with the New Google Drive:

Google has a service that creates the link for PDF's Not in GDrive: https://docs.google.com/viewer Just add your URL and it creates a link, and IFrame code (Look closely and you will see the pattern and create links without this web service)

Also, there is a way to do it for PDF's stored in Google Drive: https://docs.google.com/viewer?srcid=YOUR_GDRIVE_PDF_DOC_ID_HERE&pid=explorer&efh=false&a=v&chrome=false&embedded=true (this can be a link or the src URL of an iframe)

I've tested on Android and it brings up the PDF viewer nicely.

"What is a “static” function in C?"

Let's start at the beginning.

It´s all based upon a thing called "linkage":

"An identifier declared in different scopes or in the same scope more than once can be made to refer to the same object or function by a process called linkage. 29)There are three kinds of linkage: external, internal, and none."

Source: C18, 6.2.2/1

"In the set of translation units and libraries that constitutes an entire program, each declaration of a particular identifier with external linkage denotes the same object or function. Within one translation unit, each declaration of an identifier with internal linkage denotes the same object or function. Each declaration of an identifier with no linkage denotes a unique entity."

Source: C18, 6.2.2/2

If a function is defined without a storage-class specifier, the function has external linkage by default:

"If the declaration of an identifier for a function has no storage-class specifier, its linkage is determined exactly as if it were declared with the storage-class specifier extern."

Source: C18, 6.2.2/5

That means that - if your program is contained of several translation units/source files (.c or .cpp) - the function is visible in all translation units/source files your program has.

This can be a problem in some cases. What if you want to use f.e. two different function (definitions), but with the same function name in two different contexts (actually the file-context).

In C and C++, the static storage-class qualifier applied to a function at file scope (not a static member function of a class in C++ or a function within another block) now comes to help and signifies that the respective function is only visible inside of the translation unit/source file it was defined in and not in the other TLUs/files.

"If the declaration of a file scope identifier for an object or a function contains the storage-class specifier static, the identifier has internal linkage. 30)"

30. A function declaration can contain the storage-class specifier static only if it is at file scope; see 6.7.1.

Source: C18, 6.2.2/3

Thus, A static function only makes sense, iff:

1. Your program is contained of several translation units/source files (.c or .cpp).

and

2. You want to limit the scope of a function to the file, in which the specific function is defined.

If not both of these requirements match, you don't need to wrap your head around about qualifying a function as static.

Side Notes:

• As already mentioned, A static function has absolutely no difference at all between C and C++, as this is a feature C++ inherited from C.

It does not matter that in the C++ community, there is a heartbreaking debate about the depreciation of qualifying functions as static in comparison to the use of unnamed namespaces instead, first initialized by a misplaced paragraph in the C++03 standard, declaring the use of static functions as deprecated which soon was revised by the committee itself and removed in C++11.

This was subject to various SO questions:

Unnamed/anonymous namespaces vs. static functions

Superiority of unnamed namespace over static?

Why an unnamed namespace is a "superior" alternative to static?

Deprecation of the static keyword... no more?

In fact, it is not deprecated per C++ standard yet. Thus, the use of static functions is still legit. Even if unnamed namespaces have advantages, the discussion about using or not using static functions in C++ is subject to one´s one mind (opinion-based) and with that not suitable for this website.

1- Add a view to the content view of your cell.
2- Right click your cell.
3- Make the added view as "selectedBackgroundView"

It is possible using ogr2ogr:

(Not sure if ogr2ogr is included in postgres installation or if I got it with postgis extension.)

REST stands for REpresentational State Transfer and goes a little something like this:

We have a bunch of uniquely addressable 'entities' that we want made available via a web application. Those entities each have some identifier and can be accessed in various formats. REST defines a bunch of stuff about what GET, POST, etc mean for these purposes.

the basic idea with REST is that you can attach a bunch of 'renderers' to different entities so that they can be available in different formats easily using the same HTTP verbs and url formats.

For more clarification on what RESTful means and how it is used google rails. Rails is a RESTful framework so there's loads of good information available in its docs and associated blog posts. Worth a read even if you arent keen to use the framework. For example: http://www.sitepoint.com/restful-rails-part-i/

RESTless means not restful. If you have a web app that does not adhere to RESTful principles then it is not RESTful

May be this post (Secure Metro JAX-WS UsernameToken Web Service with Signature, Encryption and TLS (SSL)) provides more insight. As they mentioned "Remember, unless password text or digested password is sent on a secured channel or the token is encrypted, neither password digest nor cleartext password offers no real additional security. "

This might give you some idea --

CREATE TABLE #Temp 
( 
  [Rank]  [int],
  [Player Name]  [varchar](128),
  [Ranking Points] [int],
  [Country]  [varchar](128)
)


INSERT INTO #Temp
SELECT 1,'Rafael Nadal',12390,'Spain'
UNION ALL
SELECT 2,'Roger Federer',7965,'Switzerland'
UNION ALL
SELECT 3,'Novak Djokovic',7880,'Serbia'


DECLARE @xml NVARCHAR(MAX)
DECLARE @body NVARCHAR(MAX)


SET @xml = CAST(( SELECT [Rank] AS 'td','',[Player Name] AS 'td','',
       [Ranking Points] AS 'td','', Country AS 'td'

_{Additional details to the previous answer:}

While React's setState is asynchronous (both classes and hooks), and it's tempting to use that fact to explain the observed behavior, it is not the reason why it happens.

TLDR: The reason is a closure scope around an immutable const value.

Solutions:

• read the value in render function (not inside nested functions):

    useEffect(() => { setMovies(result) }, [])
    console.log(movies)
  

• add the variable into dependencies (and use the react-hooks/exhaustive-deps eslint rule):

    useEffect(() => { setMovies(result) }, [])
    useEffect(() => { console.log(movies) }, [movies])
  

• use a mutable reference (when the above is not possible):

    const moviesRef = useRef(initialValue)
    useEffect(() => {
      moviesRef.current = result
      console.log(moviesRef.current)
    }, [])
  

Explanation why it happens:

If async was the only reason, it would be possible to await setState().

However, both props and state are assumed to be unchanging during 1 render.

Treat this.state as if it were immutable.

With hooks, this assumption is enhanced by using constant values with the const keyword:

const [state, setState] = useState('initial')

The value might be different between 2 renders, but remains a constant inside the render itself and inside any closures (functions that live longer even after render is finished, e.g. useEffect, event handlers, inside any Promise or setTimeout).

Consider following fake, but synchronous, React-like implementation:

// sync implementation:

let internalState
let renderAgain

const setState = (updateFn) => {
  internalState = updateFn(internalState)
  renderAgain()
}

const useState = (defaultState) => {
  if (!internalState) {
    internalState = defaultState
  }
  return [internalState, setState]
}

const render = (component, node) => {
  const {html, handleClick} = component()
  node.innerHTML = html
  renderAgain = () => render(component, node)
  return handleClick
}

// test:

const MyComponent = () => {
  const [x, setX] = useState(1)
  console.log('in render:', x) // ?
  
  const handleClick = () => {
    setX(current => current + 1)
    console.log('in handler/effect/Promise/setTimeout:', x) // ? NOT updated
  }
  
  return {
    html: `<button>${x}</button>`,
    handleClick
  }
}

const triggerClick = render(MyComponent, document.getElementById('root'))
triggerClick()
triggerClick()
triggerClick()

<div id="root"></div>

You got the first part right:

Yes mapStateToProps has the Store state as an argument/param (provided by react-redux::connect) and its used to link the component with certain part of the store state.

By linking I mean the object returned by mapStateToProps will be provided at construction time as props and any subsequent change will be available through componentWillReceiveProps.

If you know the Observer design pattern it's exactly that or small variation of it.

An example would help make things clearer:

import React, {
    Component,
} from 'react-native';

class ItemsContainer extends Component {
    constructor(props) {
        super(props);

        this.state = {
            items: props.items, //provided by connect@mapStateToProps
            filteredItems: this.filterItems(props.items, props.filters),
        };
    }

    componentWillReceiveProps(nextProps) {
        this.setState({
            filteredItems: this.filterItems(this.state.items, nextProps.filters),
        });
    }

    filterItems = (items, filters) => { /* return filtered list */ }

    render() {
        return (
            <View>
                // display the filtered items
            </View>
        );
    }
}

module.exports = connect(
    //mapStateToProps,
    (state) => ({
        items: state.App.Items.List,
        filters: state.App.Items.Filters,
        //the State.App & state.App.Items.List/Filters are reducers used as an example.
    })
    // mapDispatchToProps,  that's another subject
)(ItemsContainer);

There can be another react component called itemsFilters that handle the display and persisting the filter state into Redux Store state, the Demo component is "listening" or "subscribed" to Redux Store state filters so whenever filters store state changes (with the help of filtersComponent) react-redux detect that there was a change and notify or "publish" all the listening/subscribed components by sending the changes to their componentWillReceiveProps which in this example will trigger a refilter of the items and refresh the display due to the fact that react state has changed.

Let me know if the example is confusing or not clear enough to provide a better explanation.

As for: This means that the state as consumed by your target component can have a wildly different structure from the state as it is stored on your store.

I didn't get the question, but just know that the react state (this.setState) is totally different from the Redux Store state!

The react state is used to handle the redraw and behavior of the react component. The react state is contained to the component exclusively.

The Redux Store state is a combination of Redux reducers states, each is responsible of managing a small portion app logic. Those reducers attributes can be accessed with the help of react-redux::connect@mapStateToProps by any component! Which make the Redux store state accessible app wide while component state is exclusive to itself.

Here you go, Python documentation on old string formatting. tutorial -> 7.1.1. Old String Formatting -> "More information can be found in the [link] section".

Note that you should start using the new string formatting when possible.

What you're seeing is integer division. To get floating point division by default,

from __future__ import division

Or, you could convert 1 or 2 of 1/2 into a floating point value.

sqrt = x**(1.0/2)

I like python numpy for this kind of stuff! eg:

r=readData()
nsorted = np.lexsort((r.calls, r.slow_requests, r.very_slow_requests, r.stalled_requests))

I have an example of importing CSV data into a numpy and ordering by column priorities. https://github.com/unixunion/toolbox/blob/master/python/csv-numpy.py

You may want to use Apache Commons IO's FileUtils.openOutputStream(File) method. It has good Exception messages when something went wrong and also creates necessary parent dirs. If everything was right then you directly get your OutputStream - very neat.

If you just want to touch the file then use FileUtils.touch(File) instead.

You cant simply (directly) convert the datareader to list.

You have to loop through all the elements in datareader and insert into list

below the sample code

using (drOutput)   
{
            System.Collections.Generic.List<CustomerEntity > arrObjects = new System.Collections.Generic.List<CustomerEntity >();        
            int customerId = drOutput.GetOrdinal("customerId ");
            int CustomerName = drOutput.GetOrdinal("CustomerName ");

        while (drOutput.Read())        
        {
            CustomerEntity obj=new CustomerEntity ();
            obj.customerId = (drOutput[customerId ] != Convert.DBNull) ? drOutput[customerId ].ToString() : null;
            obj.CustomerName = (drOutput[CustomerName ] != Convert.DBNull) ? drOutput[CustomerName ].ToString() : null;
            arrObjects .Add(obj);
        }

}

Try this: Set your image crop dimensions and use this line in your CSS:

You could set your _JAVA_OPTIONS environmental variable. For example in bash this would do the trick:

export _JAVA_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir

I put that into my bash login script and it seems to do the trick.

Intrinsic Content Size - Pretty self-explanatory, but views with variable content are aware of how big their content is and describe their content's size through this property. Some obvious examples of views that have intrinsic content sizes are UIImageViews, UILabels, UIButtons.

Content Hugging Priority - The higher this priority is, the more a view resists growing larger than its intrinsic content size.

Content Compression Resistance Priority - The higher this priority is, the more a view resists shrinking smaller than its intrinsic content size.

Check here for more explanation: AUTO LAYOUT MAGIC: CONTENT SIZING PRIORITIES

You can go to /etc/init.d/ - you will see a daemon template called skeleton.

You can duplicate it and then enter your script under the start function.

Put your mongo script into a .js file.

Then execute mongo < yourFile.js

Ex:

demo.js //file has your script

use sample  //db name
show collections

keep this file in "c:\db-scripts"

Then in cmd prompt go to "c:\db-scripts"

C:\db-scripts>mongo < demo.js

This will execute the code in mongo and shows the output

C:\db-scripts>mongo < demo.js
Mongo shell version: 3.0.4
Connecting to: test
switched to db sample
users   //collection name
tasks   //collection name
bye
C:\db-scripts>

You can try and check for the referer, which should be the parent site if you're an iframe

you can do that like this:

var href = document.referrer;

#! /bin/bash
if ((2==$#)); then
  a=$1
  b=$2
  alog=$(echo $a | tr '/' '-').log
  blog=$(echo $b | tr '/' '-').log
  git log --oneline $a > $alog
  git log --oneline $b > $blog
  diff $alog $blog
fi

Contributing this because it allows a and b logs to be diff'ed visually, side by side, if you have a visual diff tool. Replace diff command at end with command to start visual diff tool.

I had a similar situation where a download needed to stay active overnight and required a key press that refreshed my connection. I also found that the mouse move does not work. However, using notepad and a send key function appears to have done the trick. I send a space instead of a "." because if there is a [yes/no] popup, it will automatically click the default response using the spacebar. Here is the code used.

param($minutes = 120)

$myShell = New-Object -com "Wscript.Shell"

for ($i = 0; $i -lt $minutes; $i++) {
  Start-Sleep -Seconds 30
  $myShell.sendkeys(" ")
}

This function will work for the designated 120 minutes (2 Hours), but can be modified for the timing desired by increasing or decreasing the seconds of the input, or increasing or decreasing the assigned value of the minutes parameter.

Just run the script in powershell ISE, or powershell, and open notepad. A space will be input at the specified interval for the desired length of time ($minutes).

Good Luck!

If you make

Sorting a tuple is quite simple:

You can use a negative match:

Here's probably a quick approach,

With two icons shown above, you shall have a RadioGroup something like this

• change the RadioGroup's orientation to horizontal
• for each RadioButton's Properties, try giving the icon for Button under CompoundButton,
• adjust the Padding and size,
• and set the Background attribute when checked.

Unfortunately there isn't. In fact the absolute path is a bit meaningless (and potentially confusing) in the context of how Ansible runs. In a nutshell, when you invoke a playbook then for each task Ansible physically copies the module associated with the task to a temporary directory on the target machine and then invokes the module with the necessary parameters. So the absolute path on the target machine is just a temporary directory that only contains a few temporary files within it, and it doesn't even include the full playbook. Also, knowing a full path of a file on the Ansible server is pretty much useless on a target machine unless you're replicating your entire Ansible directory tree on the targets.

To see all the variables that are defined by Ansible you can simply run the following command:

$ ansible -m setup hostname

What is the reason you think you need to know the absolute path to the playbook?

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

Have a look at sys.path:

>>> import sys
>>> print(sys.path)

You can use a simple approach...

$('YourDataTableID').dataTable()._fnAjaxUpdate();

It will refresh the data by making an ajax request with the same parameters. Very simple.

Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.

src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?

Blob URLs can only be generated internally by the browser. URL.createObjectURL() will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL(). These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).

What is blob url?
Why it is used?

Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.

For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.

It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.

Can i make my own blob url on a server?

No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.

if you have then Additional detail

You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL() to generate a local URL for it:

var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
    url = URL.createObjectURL(blob),
    img = new Image();

img.onload = function() {
    URL.revokeObjectURL(this.src);     // clean-up memory
    document.body.appendChild(this);   // add image to DOM
}

img.src = url;                         // can now "stream" the bytes

Note that URL may be prefixed in webkit-browsers, so use:

var url = (URL || webkitURL).createObjectURL(...);

       driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
       driver.get("http://www.google.com");
       WebElement ele = driver.findElement(By.id("gbqfba"));
       Actions action = new Actions(driver);
       action.moveToElement(ele).build().perform();

I agree with Aamir that the submission arrow.m from Erik Johnson on the MathWorks File Exchange is a very nice option. You can use it to illustrate the different methods of vector addition like so:

• Tip-to-tail method:

  o = [0 0 0];  %# Origin
  a = [2 3 5];  %# Vector 1
  b = [1 1 0];  %# Vector 2
  c = a+b;      %# Resultant
  arrowStarts = [o; a; o];        %# Starting points for arrows
  arrowEnds = [a; c; c];          %# Ending points for arrows
  arrow(arrowStarts,arrowEnds);   %# Plot arrows
  

• Parallelogram method:

  o = [0 0 0];  %# Origin
  a = [2 3 5];  %# Vector 1
  b = [1 1 0];  %# Vector 2
  c = a+b;      %# Resultant
  arrowStarts = [o; o; o];        %# Starting points for arrows
  arrowEnds = [a; b; c];          %# Ending points for arrows
  arrow(arrowStarts,arrowEnds);   %# Plot arrows
  hold on;
  lineX = [a(1) b(1); c(1) c(1)];  %# X data for lines
  lineY = [a(2) b(2); c(2) c(2)];  %# Y data for lines
  lineZ = [a(3) b(3); c(3) c(3)];  %# Z data for lines
  line(lineX,lineY,lineZ,'Color','k','LineStyle',':');  %# Plot lines

List_of_list =[([z for z in range(x-2,x+1) if z >= 0],y) for y in range(10) for x in range(10)]

This should do the trick. And the output is this:

[([0], 0), ([0, 1], 0), ([0, 1, 2], 0), ([1, 2, 3], 0), ([2, 3, 4], 0),  ([3, 4, 5], 0), ([4, 5, 6], 0), ([5, 6, 7], 0), ([6, 7, 8], 0), ([7, 8, 9], 0), ([0], 1), ([0, 1], 1), ([0, 1, 2], 1), ([1, 2, 3], 1), ([2, 3, 4], 1), ([3, 4, 5], 1), ([4, 5, 6], 1), ([5, 6, 7], 1), ([6, 7, 8], 1), ([7, 8, 9], 1), ([0], 2), ([0, 1], 2), ([0, 1, 2], 2), ([1, 2, 3], 2), ([2, 3, 4], 2), ([3, 4, 5], 2), ([4, 5, 6], 2), ([5, 6, 7], 2), ([6, 7, 8], 2), ([7, 8, 9], 2), ([0], 3), ([0, 1], 3), ([0, 1, 2], 3), ([1, 2, 3], 3), ([2, 3, 4], 3), ([3, 4, 5], 3), ([4, 5, 6], 3), ([5, 6, 7], 3), ([6, 7, 8], 3), ([7, 8, 9], 3), ([0], 4), ([0, 1], 4), ([0, 1, 2], 4), ([1, 2, 3], 4), ([2, 3, 4], 4), ([3, 4, 5], 4), ([4, 5, 6], 4), ([5, 6, 7], 4), ([6, 7, 8], 4), ([7, 8, 9], 4), ([0], 5), ([0, 1], 5), ([0, 1, 2], 5), ([1, 2, 3], 5), ([2, 3, 4], 5), ([3, 4, 5], 5), ([4, 5, 6], 5), ([5, 6, 7], 5), ([6, 7, 8], 5), ([7, 8, 9], 5), ([0], 6), ([0, 1], 6), ([0, 1, 2], 6), ([1, 2, 3], 6), ([2, 3, 4], 6), ([3, 4, 5], 6), ([4, 5, 6], 6), ([5, 6, 7], 6), ([6, 7, 8], 6), ([7, 8, 9], 6), ([0], 7), ([0, 1], 7), ([0, 1, 2], 7), ([1, 2, 3], 7), ([2, 3, 4], 7), ([3, 4, 5], 7), ([4, 5, 6], 7), ([5, 6, 7], 7), ([6, 7, 8], 7), ([7, 8, 9], 7), ([0], 8), ([0, 1], 8), ([0, 1, 2], 8), ([1, 2, 3], 8), ([2, 3, 4], 8), ([3, 4, 5], 8), ([4, 5, 6], 8), ([5, 6, 7], 8), ([6, 7, 8], 8), ([7, 8, 9], 8), ([0], 9), ([0, 1], 9), ([0, 1, 2], 9), ([1, 2, 3], 9), ([2, 3, 4], 9), ([3, 4, 5], 9), ([4, 5, 6], 9), ([5, 6, 7], 9), ([6, 7, 8], 9), ([7, 8, 9], 9)]    

This is done by list comprehension(which makes looping elements in a list via one line code possible). The logic behind this one-line code is the following:

(1) for x in range(10) and for y in range(10) are employed for two independent loops inside a list

(2) (a list, y) is the general term of the loop, which is why it is placed before two for's in (1)

(3) the length of the list in (2) cannot exceed 3, and the list depends on x, so

[z for z in range(x-2,x+1)] 

is used

(4) because z starts from zero but range(x-2,x+1) starts from -2 which isn't what we want, so a conditional statement if z >= 0 is placed at the end of the list in (2)

[z for z in range(x-2,x+1) if z >= 0] 

This can be done with tables:

<table cellpadding="0" cellspacing="0" width="100%" height="100%">
    <tr height="0%"><td>
        <div id="full">
            <!--contents of 1 -->
        </div>
    </td></tr>
    <tr><td>
        <div id="someid">
            <!--contents of 2 -->
        </div>
    </td></tr>
</table>

Then apply css to make someid fill the remaining space:

#someid {
    height: 100%;
}

Now, I can just hear the angry shouts from the crowd, "Oh noes, he's using tables! Feed him to the lions!" Please hear me out.

Unlike the accepted answer which accomplishes nothing aside from making the container div the full height of the page, this solution makes div #2 fill the remaining space as requested in the question. If you need that second div to fill the full height allotted to it, this is currently the only way to do it.

But feel free to prove me wrong, of course! CSS is always better.

I've had problems trying to do it in pure CSS - depending on the font it can look a bit rubbish. As an alternative you can use SVG/VML to do it. There are libraries that help make it cross browser with ease e.g. Raphael and ExtJS. In ExtJS4 the code looks like this:

    var drawComp = Ext.create('Ext.draw.Component', {
        renderTo: Ext.getBody(), //or whatever..
        height: 100, width: 100 //ditto..
    });
    var text = Ext.create('Ext.draw.Component', {
        type: "text",
        text: "The text to draw",
        rotate: {
            x: 0, y: 0, degrees: 270
        },
        x: -50, y: 10 //or whatever to fit (you could calculate these)..
    });
    text.show(true);

This will work in IE6+ and all modern browsers, however, unfortunately I think you need at least FF3.0.

I had a similar problem and I even tried running my CMD with administrator rights, but it did not solve the problem.

The basic thing is to make sure to change the Directory in cmd to the current directory where your jar file is.

Do the following steps:

1. Copy jar file to Desktop.

2. Run CMD

3. Type command cd desktop

4. Then type java -jar filename.jar

This should work.

Edit: From JDK-11 onwards ( JEP 330: Launch Single-File Source-Code Programs )

Since Java 11, java command line tool has been able to run a single-file source-code directly. e.g.

java filename.java

 BigDecimal decPrec = (BigDecimal)yo.get("Avg");
 decPrec = decPrec.setScale(5, RoundingMode.CEILING);
 String value= String.valueOf(decPrec);

This way you can set specific precision of a BigDecimal.

The value of decPrec was 1.5726903423607562595809913132345426 which is rounded off to 1.57267.

BufferedWriter login = new BufferedWriter(new FileWriter("login.txt"));

is an example if you want to create a file in one line.

Simple TypeScript example

NOTE: While I agree with @Stefan in many things, I only needed a simple match highlighting:

module myApp.Search {
    'use strict';

    export class Utils {
        private static regexFlags = 'gi';
        private static wrapper = 'mark';

        private static wrap(match: string): string {
            return '<' + Utils.wrapper + '>' + match + '</' + Utils.wrapper + '>';
        }

        static highlightSearchTerm(term: string, searchResult: string): string {
            let regex = new RegExp(term, Utils.regexFlags);

            return searchResult.replace(regex, match => Utils.wrap(match));
        }
    }
}

And then constructing the actual result:

module myApp.Search {
    'use strict';

    export class SearchResult {
        id: string;
        title: string;

        constructor(result, term?: string) {
            this.id = result.id;
            this.title = term ? Utils.highlightSearchTerm(term, result.title) : result.title;
        }
    }
}

Since it is your files in your app bundle, I think you can use pathForResource:ofType: to get the full pathname of your file.

Here is an example:

NSString* filePath = [[NSBundle mainBundle] pathForResource:@"your_file_name" 
                                            ofType:@"the_file_extension"];

That depends. If that definition is global (outside any function) then num will be initialized to zero. If it's local (inside a function) then its value is indeterminate. In theory, even attempting to read the value has undefined behavior -- C allows for the possibility of bits that don't contribute to the value, but have to be set in specific ways for you to even get defined results from reading the variable.

Edit / Update:

If you are using Typescript 3.7 or newer you can now also do:

    const data = change?.after?.data();

    if(!data) {
      console.error('No data here!');
       return null
    }

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }

Original Response

Typescript is saying that change or data is possibly undefined (depending on what onUpdate returns).

So you should wrap it in a null/undefined check:

if(change && change.after && change.after.data){
    const data = change.after.data();

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }
}

If you are 100% sure that your object is always defined then you can put this:

const data = change.after!.data();

The issue is that you are trying to have multiple statements in an if without using {}. What you currently have is interpreted like:

if( choice==5 )
{
    System.out.println( ... );
}
break;
else
{
    //...
}

You really want:

if( choice==5 )
{
    System.out.println( ... );
    break;
}
else
{
    //...
}

Also, as Farce has stated, it would be better to use else if for all the conditions instead of if because if choice==1, it will still go through and check if choice==5, which would fail, and it will still go into your else block.

if( choice==1 )
    //...
else if( choice==2 )
    //...
else if( choice==3 )
    //...
else if( choice==4 )
    //...
else if( choice==5 )
{
    //...
}
else
    //...

A more elegant solution would be using a switch statement. However, break only breaks from the most inner "block" unless you use labels. So you want to label your loop and break from that if the case is 5:

LOOP:
for(;;)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch( choice )
    {
        case 1:
            playGame();
            break;
        case 2:
            loadGame();
            break;
        case 2:
            options();
            break;
        case 4:
            credits();
            break;
        case 5:
            System.out.println("End of Game\n Thank you for playing with us!");
            break LOOP;
        default:
            System.out.println( ... );
    }
}

Instead of labeling the loop, you could also use a flag to tell the loop to stop.

bool finished = false;
while( !finished )
{
    switch( choice )
    {
        // ...
        case 5:
            System.out.println( ... )
            finished = true;
            break;
        // ...
    }
}

You should rather use the attribute placeholder to give the default value to the text input field.

e.g.

<input type="text" size="32" placeholder="1000" name="fee" />

Here is a tested and working generic solution:

I have a large number UpDownNumeric controls, some in the main form, some in groupboxes within the form. I want only the one last selected control to change back-color to green, for which I first set all others to white, using this method: (can also expand to grandchildren)

    public void setAllUpDnBackColorWhite()
    {
        //To set the numericUpDown background color of the selected control to white: 
        //and then the last selected control will change to green.

        foreach (Control cont in this.Controls)
        {
           if (cont.HasChildren)
            {
                foreach (Control contChild in cont.Controls)
                    if (contChild.GetType() == typeof(NumericUpDown))
                        contChild.BackColor = Color.White;
            }
            if (cont.GetType() == typeof(NumericUpDown))
                cont.BackColor = Color.White;
       }
    }   

You would use the os module system method.

You just put in the string form of the command, the return value is the windows enrivonment variable COMSPEC

For example:

os.system('python') opens up the windows command prompt and runs the python interpreter

If you simply open the file for writing with the truncate-option, you'll delete the content.

std::ofstream ofs;
ofs.open("test.txt", std::ofstream::out | std::ofstream::trunc);
ofs.close();
