See adeneo's answer, but don't forget encodeURIComponent!

a.href     = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csvString);

Also, I needed to do "\r\n" not just "\n" for the row delimiter.

var csvString = csvRows.join("\r\n");

Revised fiddle: http://jsfiddle.net/7Q3c6/

The issue is this, you want to know if the error is not empty.

public function getError() {
    return $this->error;
}

Adding a method isErrorSet() will solve the problem.

public function isErrorSet() {
    if (isset($this->error) && !empty($this->error)) {
        return true;
    } else {
        return false;
    }
}

Now this will work fine with this code with no notice.

if (!($x->isErrorSet())) {
    echo $x->getError();
}

Instructions:

1. Click on the Terminal icon in the desktop panel to open a terminal window and access the command prompt.
2. Type the command which java to find the path to the Java executable file.
3. Type the command su - to become the root user.
4. Type the command vi /root/.bash_profile to open the system bash_profile file in the Vi text editor. You can replace vi with your preferred text editor.
5. Type export JAVA_HOME=/usr/local/java/ at the bottom of the file. Replace /usr/local/java with the location found in step two.
6. Save and close the bash_profile file.
7. Type the command exit to close the root session.
8. Log out of the system and log back in.
9. Type the command echo $JAVA_HOME to ensure that the path was set correctly.

Here is my solution. Just get a reference to your view and call this method:

public static void animateViewFromBottomToTop(final View view){

    view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

        @Override
        public void onGlobalLayout() {

            view.getViewTreeObserver().removeOnGlobalLayoutListener(this);

            final int TRANSLATION_Y = view.getHeight();
            view.setTranslationY(TRANSLATION_Y);
            view.setVisibility(View.GONE);
            view.animate()
                .translationYBy(-TRANSLATION_Y)
                .setDuration(500)
                .setStartDelay(200)
                .setListener(new AnimatorListenerAdapter() {

                    @Override
                    public void onAnimationStart(final Animator animation) {

                        view.setVisibility(View.VISIBLE);
                    }
                })
                .start();
        }
    });
}

No need to do anything else =)

in template

<md-button class="md-fab md-mini md-warn md-ink-ripple" ng-click="export()" aria-label="Export">
<md-icon class="material-icons" alt="Export" title="Export" aria-label="Export">
    system_update_alt
</md-icon></md-button>

in controller

     $scope.export = function(){ $window.location.href = $scope.export; };

You should put it into a function like this:

public static int toInt(byte[] bytes, int offset) {
  int ret = 0;
  for (int i=0; i<4 && i+offset<bytes.length; i++) {
    ret <<= 8;
    ret |= (int)bytes[i] & 0xFF;
  }
  return ret;
}

Example:

byte[] bytes = new byte[]{-2, -4, -8, -16};
System.out.println(Integer.toBinaryString(toInt(bytes, 0)));

Output:

11111110111111001111100011110000

This takes care of running out of bytes and correctly handling negative byte values.

I'm unaware of a standard function for doing this.

Issues to consider:

1. Endianness: different CPU architectures put the bytes that make up an int in different orders. Depending on how you come up with the byte array to begin with you may have to worry about this; and

2. Buffering: if you grab 1024 bytes at a time and start a sequence at element 1022 you will hit the end of the buffer before you get 4 bytes. It's probably better to use some form of buffered input stream that does the buffered automatically so you can just use readByte() repeatedly and not worry about it otherwise;

3. Trailing Buffer: the end of the input may be an uneven number of bytes (not a multiple of 4 specifically) depending on the source. But if you create the input to begin with and being a multiple of 4 is "guaranteed" (or at least a precondition) you may not need to concern yourself with it.

to further elaborate on the point of buffering, consider the BufferedInputStream:

InputStream in = new BufferedInputStream(new FileInputStream(file), 1024);

Now you have an InputStream that automatically buffers 1024 bytes at a time, which is a lot less awkward to deal with. This way you can happily read 4 bytes at a time and not worry about too much I/O.

Secondly you can also use DataInputStream:

InputStream in = new DataInputStream(new BufferedInputStream(
                     new FileInputStream(file), 1024));
byte b = in.readByte();

or even:

int i = in.readInt();

and not worry about constructing ints at all.

The problem with your CSS lies with the syntax of your pseudo-classes.

The even and odd pseudo-classes should be:

li:nth-child(even) {
    color:green;
}

and

li:nth-child(odd) {
    color:red;
}

Here is a Java 8 based solution, using the new java.time package (Tutorial).

If you can use Java 8 objects in your code, use LocalDateTime:

LocalDateTime now = LocalDateTime.now(); // current date and time
LocalDateTime midnight = now.toLocalDate().atStartOfDay();

If you require legacy dates, i.e. java.util.Date:

Convert the LocalDateTime you created above to Date using these conversions:

LocalDateTime -> ZonedDateTime -> Instant -> Date

1. Call atZone(zone) with a specified time-zone (or ZoneId.systemDefault() for the system default time-zone) to create a ZonedDateTime object, adjusted for DST as needed.

   ZonedDateTime zdt = midnight.atZone(ZoneId.of("America/Montreal"));
   

2. Call toInstant() to convert the ZonedDateTime to an Instant:

   Instant i = zdt.toInstant()
   

3. Finally, call Date.from(instant) to convert the Instant to a Date:

   Date d1 = Date.from(i)
   

In summary it will look similar to this for you:

LocalDateTime now = LocalDateTime.now(); // current date and time
LocalDateTime midnight = now.toLocalDate().atStartOfDay();
Date d1 = Date.from(midnight.atZone(ZoneId.systemDefault()).toInstant());
Date d2 = Date.from(now.atZone(ZoneId.systemDefault()).toInstant());

See also section Legacy Date-Time Code (The Java™ Tutorials) for interoperability of the new java.time functionality with legacy java.util classes.

Explanations:
Let's say there is windows A1 and B1 and websites A2 and B2.
Instead of opening B2 in B1 and then return to A1, I open B2 in A1 and re-open A2 in B1.
(Another thing that makes it work is that I don't make the user re-download A2, see line 4)

^{The only thing you may doesn't like is that the new tab opens before the main page.}

This solution only for chrome browser. I am not sure about other browser.

1. Add "Modify Content-Type Options" extension in chrome browser.
2. Open "chrome-extension://jnfofbopfpaoeojgieggflbpcblhfhka/options.html" url in browser.
3. Add the rule for raw file url. For example:
   • URL Filter: https:///raw/master//fileName.html
   • Original Type: text/plain
   • Replacement Type: text/html
4. Open the file browser which you added url in rule (in step 3).

gradle supports ndk compilation by generating another Android.mk file with absolute paths to your sources. NDK supports absolute paths since r9 on OSX, r9c on Windows, so you need to upgrade your NDK to r9+.

You may run into other troubles as NDK support by gradle is preliminary. If so you can deactivate the ndk compilation from gradle by setting:

sourceSets.main {
    jni.srcDirs = []
    jniLibs.srcDir 'src/main/libs'
}

to be able to call ndk-build yourself and integrate libs from libs/.

btw, you have any issue compiling for x86 ? I see you haven't included it in your APP_ABI.

To help people who might search for answer to this same question, it is important to know what type of projects you are using in Studio.

Gradle

The default project type when creating new project, and the recommended one in general is Gradle.

For a new project called "Foo", the structure under the main folder will be

Foo/
    settings.gradle
    Foo/
        build.gradle
        build/

Where the internal "Foo" folder is the main module (this structure allows you to create more modules later on in the same structure without changes).

In this setup, the location of the generated APK will be under

Foo/Foo/build/apk/...

Note that each module can generate its own output, so the true output is more

Foo/*/build/apk/...

EDIT On the newest version of the Android Studio location path for generated output is

Foo/*/build/outputs/apk/...

IntelliJ

If you are a user of IntelliJ before switching to Studio, and are importing your IntelliJ project directly, then nothing changed. The location of the output will be the same under:

out/production/...

Note: this is will become deprecated sometimes around 1.0

Eclipse

If you are importing Android Eclipse project directly, do not do this! As soon as you have dependencies in your project (jars or Library Projects), this will not work and your project will not be properly setup. If you have no dependencies, then the apk would be under the same location as you'd find it in Eclipse:

bin/...

However I cannot stress enough the importance of not doing this.

SQL Server 2016 Answer

With SQL Server 2016 you can now do (MSDN Source):

DROP VIEW IF EXISTS dbo.MyView

If you want to center the spinner using AutoLayout, do:

UIActivityIndicatorView *activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[activityView startAnimating];
[self.view addSubview:activityView];
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:activityView
                                                      attribute:NSLayoutAttributeCenterX
                                                      relatedBy:NSLayoutRelationEqual
                                                         toItem:self.view
                                                      attribute:NSLayoutAttributeCenterX
                                                     multiplier:1.0
                                                       constant:0.0]];
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:activityView
                                                      attribute:NSLayoutAttributeCenterY
                                                      relatedBy:NSLayoutRelationEqual
                                                         toItem:self.view
                                                      attribute:NSLayoutAttributeCenterY
                                                     multiplier:1.0
                                                       constant:0.0]];

If you have additional types, edit the selector:

var formElements = new Array();
$("form :input").each(function(){
    formElements.push($(this));
});

All form elements are now in the array formElements.

All of the answers above are correct; attr_reader and attr_writer are more convenient to write than manually typing the methods they are shorthands for. Apart from that they offer much better performance than writing the method definition yourself. For more info see slide 152 onwards from this talk (PDF) by Aaron Patterson.

If you are using redus you can create an action to store data and check the value in parent Component or you can use AsyncStorage.

But I think it's better to passing only JSON-serializable params, because if someday you want to save state of navigation, its not very easy.

Also note react-navigation has this feature in experimental https://reactnavigation.org/docs/en/state-persistence.html

Each param, route, and navigation state must be fully JSON-serializable for this feature to work. This means that your routes and params must contain no functions, class instances, or recursive data structures.

I like this feature in Development Mode and when I pass params as function I simply can't use it

This simplifies it a bit and it behaves as you want it.

Nice solution from Codeaddict. I took the liberty of implementing a version of it in Ruby:

def find_sum(arr,sum)
 result ={}
 h = Hash[arr.map {|i| [i,i]}]
 arr.each { |l| result[l] = sum-l  if h[sum-l] && !result[sum-l]  }
 result
end

To allow duplicate pairs (1,5), (5,1) we just have to remove the && !result[sum-l] instruction

I search so often that I've found it useful to map the underscore key to remove the search highlight:

nnoremap <silent> _ :nohl<CR>

You can use the "New Class" dialog, but that leaves other steps you need to do by hand (e.g. adding an entry to the manifest file). If you want those steps to be automated, you can create the activity via the manifest editor like this:

1. Double click on AndroidManifest.xml in the package explorer.
2. Click on the "Application" tab of the manifest editor
3. Click on "Add.." under the "Application Nodes" heading (bottom left of the screen)
4. Choose Activity from the list in the dialog that pops up (if you have the option, you want to create a new top-level element)
5. Click on the "Name*" link under the "Attributes for" header (bottom right of the window) to create a class for the new activity.

When you click Finish from the new class dialog, it'll take you to your new activity class so you can start coding.

Five steps might seem a lot, but I'm just trying to be extra detailed here so that it's clear. It's pretty quick when you actually do it.

PHP will let you build the pages of your site that make up your video conferencing and chat applications, but it won't deliver or stream video for you - PHP runs on the server only and renders out HTML to a client browser.

For the video, the first thing you'll need is a live streaming account with someone like akamai or the numerous others in the field. Using this account gives you an ingress point for your video - ie: the server that you will stream your live video up to.

Next, you want to get your video out to the browsers - windows media player, flash or silverlight will let you achieve this - embedding the appropriate control for your chosen technology into your page (using PHP or whatever) and given the address of your live video feed.

PHP (or other scripting language) would be used to build the chat part of the application and bring the whole thing together (the chat and the embedded video player).

Hope this helps.

PEAR::Mail_Mime? Sure, PEAR dependency of (min) 2 files (just mail_mime itself if you edit it to remove the pear dependencies), but it works well. Additionally, most servers have PEAR installed to some extent, and in the best cases they have Pear/Mail and Pear/Mail_Mime. Something that cannot be said for most other libraries offering the same functionality.

You may also consider looking in to PHP's IMAP extension. It's a little more complicated, and requires more setup (not enabled or installed by default), but is must more efficient at compilng and sending messages to an IMAP capable server.

I got this error after creating a new sysadmin user under my SQL instance. My admin user was created under a specific domain MyOrganization/useradmin

Using useradmin on a disconnected environment allows you to create other users using SQL Server authentication, but as soon as you try to login you get

Microsoft SQL Server Error: 18456

To fix the problem, try to connect again to your Organization network and create the user while you are connected and then you can get disconnected and will work.

If you are using Reactive form you can set it to default like this:

In the form model, set the value to false. So if it's checked its value will be true else false

let form = this.formBuilder.group({
    is_known: [false]
})

//In HTML

 <mat-checkbox matInput formControlName="is_known">Known</mat-checkbox>

You are trying to access an XLS file. However, you are using XSSFWorkbook and XSSFSheet class objects. These classes are mainly used for XLSX files.

For XLS file: HSSFWorkbook & HSSFSheet
For XLSX file: XSSFSheet & XSSFSheet

So in place of XSSFWorkbook use HSSFWorkbook and in place of XSSFSheet use HSSFSheet.

So your code should look like this after the changes are made:

HSSFWorkbook workbook = new HSSFWorkbook(file);

HSSFSheet sheet = workbook.getSheetAt(0);

Try:

-webkit-transition: all .2s linear, background-position 0;

This worked for me on something similar..

scrollHeight is a regular javascript property so you don't need jQuery.

var test = document.getElementById("foo").scrollHeight;

$startinfo = new-object System.Diagnostics.ProcessStartInfo 
$startinfo.FileName = "explorer.exe"
$startinfo.WorkingDirectory = 'D:\foldername'

[System.Diagnostics.Process]::Start($startinfo)

Hope this helps

In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.

Solution

• I assume you have installed the pip matplotlib, there is a directory in your root called ~/.matplotlib.
• Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg

From this link you can try different diagrams.

Delete the node_modules folder

Then you should run the commands:

npm install --no-bin-links

npm run dev

It's worked on my Laravel 5.5 and Windows.

This could be done simpler:

<base href="${pageContext.request.contextPath}/"/>

All URL will be formed without unnecessary domain:port but with application context.

you will need to reference the "btime" in /proc/stat, which is the Unix epoch time when the system was latest booted. Then you could base on that system boot time and then add on the elapsed seconds given in dmesg to calculate timestamp for each events.

Anyway @Nate Cook's answer is accepted but I would like to improve it with better date format.

with Swift 2.2, I can get desired formatted date

//TimeStamp
let timeInterval  = 1415639000.67457
print("time interval is \(timeInterval)")

//Convert to Date
let date = NSDate(timeIntervalSince1970: timeInterval)

//Date formatting
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd, MMMM yyyy HH:mm:a"
dateFormatter.timeZone = NSTimeZone(name: "UTC")
let dateString = dateFormatter.stringFromDate(date)
print("formatted date is =  \(dateString)")

the result is

time interval is 1415639000.67457

formatted date is = 10, November 2014 17:03:PM

Certainly not as I expected...

In the context of Drupal, the difference will depend whether clean URLs are on or not.

With them off, $_SERVER['REQUEST_URI'] will have the full path of the page as called w/ /index.php, while $_GET["q"] will just have what is assigned to q.

With them on, they will be nearly identical w/o other arguments, but $_GET["q"] will be missing the leading /. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.

I think you would want to add an 'onSelect' event handler to the initialization of your datepicker so your code gets triggered when the user selects a date. Try it out on jsFiddle

$(document).ready(function(){
    // Datepicker
    $('#datepicker').datepicker({
        dateFormat: 'yy-mm-dd',
        inline: true,
        minDate: new Date(2010, 1 - 1, 1),
        maxDate:new Date(2010, 12 - 1, 31),
        altField: '#datepicker_value',
        onSelect: function(){
            var day1 = $("#datepicker").datepicker('getDate').getDate();                 
            var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1;             
            var year1 = $("#datepicker").datepicker('getDate').getFullYear();
            var fullDate = year1 + "-" + month1 + "-" + day1;
            var str_output = "<h1><center><img src=\"/images/a" + fullDate +".png\"></center></h1><br/><br>";
            $('#page_output').html(str_output);
        }
    });
});

Try this

String[] array = values.split("\\|",-1); 

I was getting a cross domain permissions issue when trying to run the answer to this question so I went with:

function UrlExists(url) {
$('<img src="'+ url +'">').load(function() {
    return true;
}).bind('error', function() {
    return false;
});
}

It seems to work great, hope this helps someone!

There's no need for "else" in this case:

IF EXISTS(SELECT *  FROM  table1  WHERE Name='John' ) return 1
return 0

Although it's not listed on the API doc page anymore, I found a thread that mentions that you can use self in place of user-id for the users/{user-id} endpoint and it'll return the currently authenticated user's info.

So, users/self is the same as an explicit call to users/{some-user-id} and contains the user's id as part of the payload. Once you're authenticated, just make a call to users/self and the result will include the currently authenticated user's id, like so:

{
    "data": {
        "id": "1574083",
        "username": "snoopdogg",
        "full_name": "Snoop Dogg",
        "profile_picture": "http://distillery.s3.amazonaws.com/profiles/profile_1574083_75sq_1295469061.jpg",
        "bio": "This is my bio",
        "website": "http://snoopdogg.com",
        "counts": {
            "media": 1320,
            "follows": 420,
            "followed_by": 3410
        }
}

For the first one: your program will go through the loop once for every row in the result set returned by the query. You can know in advance how many results there are by using mysql_num_rows().

For the second one: this time you are only using one row of the result set and you are doing something for each of the columns. That's what the foreach language construct does: it goes through the body of the loop for each entry in the array $row. The number of times the program will go through the loop is knowable in advance: it will go through once for every column in the result set (which presumably you know, but if you need to determine it you can use count($row)).

Here you wanna make a pointer to the first element of the array

uint8_t (*matrix_ptr)[20] = l_matrix;

With typedef, this looks cleaner

typedef uint8_t array_of_20_uint8_t[20];
array_of_20_uint8_t *matrix_ptr = l_matrix;

Then you can enjoy life again :)

matrix_ptr[0][1] = ...;

Beware of the pointer/array world in C, much confusion is around this.

Edit

Reviewing some of the other answers here, because the comment fields are too short to do there. Multiple alternatives were proposed, but it wasn't shown how they behave. Here is how they do

uint8_t (*matrix_ptr)[][20] = l_matrix;

If you fix the error and add the address-of operator & like in the following snippet

uint8_t (*matrix_ptr)[][20] = &l_matrix;

Then that one creates a pointer to an incomplete array type of elements of type array of 20 uint8_t. Because the pointer is to an array of arrays, you have to access it with

(*matrix_ptr)[0][1] = ...;

And because it's a pointer to an incomplete array, you cannot do as a shortcut

matrix_ptr[0][0][1] = ...;

Because indexing requires the element type's size to be known (indexing implies an addition of an integer to the pointer, so it won't work with incomplete types). Note that this only works in C, because T[] and T[N] are compatible types. C++ does not have a concept of compatible types, and so it will reject that code, because T[] and T[10] are different types.

The following alternative doesn't work at all, because the element type of the array, when you view it as a one-dimensional array, is not uint8_t, but uint8_t[20]

uint8_t *matrix_ptr = l_matrix; // fail

The following is a good alternative

uint8_t (*matrix_ptr)[10][20] = &l_matrix;

You access it with

(*matrix_ptr)[0][1] = ...;
matrix_ptr[0][0][1] = ...; // also possible now

It has the benefit that it preserves the outer dimension's size. So you can apply sizeof on it

sizeof (*matrix_ptr) == sizeof(uint8_t) * 10 * 20

There is one other answer that makes use of the fact that items in an array are contiguously stored

uint8_t *matrix_ptr = l_matrix[0];

Now, that formally only allows you to access the elements of the first element of the two dimensional array. That is, the following condition hold

matrix_ptr[0] = ...; // valid
matrix_ptr[19] = ...; // valid

matrix_ptr[20] = ...; // undefined behavior
matrix_ptr[10*20-1] = ...; // undefined behavior

You will notice it probably works up to 10*20-1, but if you throw on alias analysis and other aggressive optimizations, some compiler could make an assumption that may break that code. Having said that, i've never encountered a compiler that fails on it (but then again, i've not used that technique in real code), and even the C FAQ has that technique contained (with a warning about its UB'ness), and if you cannot change the array type, this is a last option to save you :)

final long startTime = System.currentTimeMillis();
for (int i = 0; i < length; i++) {
  // Do something
}
final long endTime = System.currentTimeMillis();

System.out.println("Total execution time: " + (endTime - startTime));

This is how I achieved it in my code:

if($('.citiescheckbox:checked').length == $('.citiescheckbox').length){
    $('.citycontainer').hide();
}else{
    $('.citycontainer').show();
}

Turns out you can't use the root user in 5.7 anymore without becoming a sudoer. That means you can't just run mysql -u root anymore and have to do sudo mysql -u root instead.

That also means that it will no longer work if you're using the root user in a GUI (or supposedly any non-command line application). To make it work you'll have to create a new user with the required privileges and use that instead.

See this answer for more details.

You can do:

flask.jsonify(**data)

or

flask.jsonify(id=str(album.id), title=album.title)

Kotlin Solution

Kotlin has a built-in function for this, removeSuffix (Documentation)

var text = "filename.xml"
text = text.removeSuffix(".xml") // "filename"

If the suffix does not exist in the string, it just returns the original

var text = "not_a_filename"
text = text.removeSuffix(".xml") // "not_a_filename"

You can also check out removePrefix and removeSurrounding which are similar

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

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

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

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

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

<?php
$stop_date = '2009-09-30 20:24:00';
echo 'date before day adding: ' . $stop_date; 
$stop_date = date('Y-m-d H:i:s', strtotime($stop_date . ' +1 day'));
echo 'date after adding 1 day: ' . $stop_date;
?>

For PHP 5.2.0+, you may also do as follows:

$stop_date = new DateTime('2009-09-30 20:24:00');
echo 'date before day adding: ' . $stop_date->format('Y-m-d H:i:s'); 
$stop_date->modify('+1 day');
echo 'date after adding 1 day: ' . $stop_date->format('Y-m-d H:i:s');

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

You have basically two options:

• go the EF way all the way, in that case, you would
  • load the object based on the userId provided - the entire object gets loaded
  • update the password field
  • save the object back using the context's .SaveChanges() method

In this case, it's up to EF how to handle this in detail. I just tested this, and in the case I only change a single field of an object, what EF creates is pretty much what you'd create manually, too - something like:

`UPDATE dbo.Users SET Password = @Password WHERE UserId = @UserId`

So EF is smart enough to figure out what columns have indeed changed, and it will create a T-SQL statement to handle just those updates that are in fact necessary.

• you define a stored procedure that does exactly what you need, in T-SQL code (just update the Password column for the given UserId and nothing else - basically executes UPDATE dbo.Users SET Password = @Password WHERE UserId = @UserId) and you create a function import for that stored procedure in your EF model and you call this function instead of doing the steps outlined above

The magic here is maven.multiModuleProjectDirectory. This folder is always the folder where you started your maven build.

Here is simple Android Code for detecting gesture direction

In MainActivity.java and activity_main.xml, write the following code:

MainActivity.java

import java.util.ArrayList;

import android.app.Activity;
import android.gesture.Gesture;
import android.gesture.GestureLibraries;
import android.gesture.GestureLibrary;
import android.gesture.GestureOverlayView;
import android.gesture.GestureOverlayView.OnGesturePerformedListener;
import android.gesture.GestureStroke;
import android.gesture.Prediction;
import android.os.Bundle;
import android.widget.Toast;

public class MainActivity extends Activity implements
        OnGesturePerformedListener {

    GestureOverlayView gesture;
    GestureLibrary lib;
    ArrayList<Prediction> prediction;

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

        lib = GestureLibraries.fromRawResource(MainActivity.this,
                R.id.gestureOverlayView1);
        gesture = (GestureOverlayView) findViewById(R.id.gestureOverlayView1);
        gesture.addOnGesturePerformedListener(this);
    }

    @Override
    public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
        ArrayList<GestureStroke> strokeList = gesture.getStrokes();
        // prediction = lib.recognize(gesture);
        float f[] = strokeList.get(0).points;
        String str = "";

        if (f[0] < f[f.length - 2]) {
            str = "Right gesture";
        } else if (f[0] > f[f.length - 2]) {
            str = "Left gesture";
        } else {
            str = "no direction";
        }
        Toast.makeText(getApplicationContext(), str, Toast.LENGTH_LONG).show();

    }

}

activity_main.xml

<android.gesture.GestureOverlayView xmlns:android="http://schemas.android.com/apk/res/android"

After the play() command add a delay of say 10 secs or so, it'll work

import pygame

import time

pygame.init()

pygame.mixer.music.load("test.wav")

pygame.mixer.music.play()

time.sleep(10)

This also plays .mp3 files.

The answers here are all quite old.

In the HTML5 world, you should the use onpopstate event.

window.onpopstate = function(event)
{
    alert("location: " + document.location + ", state: " + JSON.stringify(event.state));
};

Or:

window.addEventListener('popstate', function(event)
{
    alert("location: " + document.location + ", state: " + JSON.stringify(event.state));
});

The latter snippet allows multiple event handlers to exist, whereas the former will replace any existing handler which may cause hard-to-find bugs.

try:
  #treat object as iterable
except TypeError, e:
  #object is not actually iterable

Don't run checks to see if your duck really is a duck to see if it is iterable or not, treat it as if it was and complain if it wasn't.

on unix you should have GNU dates installed. you do not need to deviate from bash. here is the strung out solution considering days, just to show the steps. it can be simplified and extended to full dates.

DATE=$(echo `date`)
DATENOW=$(echo `date -d "$DATE" +%j`)
DATECOMING=$(echo `date -d "20131220" +%j`)
THEDAY=$(echo `expr $DATECOMING - $DATENOW`)

echo $THEDAY 

I have read all the answers here and none of them was complete answer for my situation (which is exactly the same in this question) so here is how I gathered some parts of the suggested answers and come up with the exact solution:

1. Land on your server's real 403 page. (Go to a forbidden URL on your server, or go to any 403 page you like)
2. Right-click and select 'view source'. Select all the source and save it to file on your domain like: http://domain.com/403.html
3. now go to your real forbidden page (or a forbidden situation in some part of your php) example: http://domain.com/members/this_is_forbidden.php

4. echo this code below before any HTML output or header! (even a whitespace will cause PHP to send HTML/TEXT HTTP Header and it won't work) The code below should be your first line!

       <?php header('HTTP/1.0 403 Forbidden');
       $contents = file_get_contents('/home/your_account/public_html/domain.com/403.html', TRUE);
       exit($contents);
   

Now you have the exact solution. I checked and verified with CPANEL Latest Visitors and it is registered as exact 403 event.

Since Facebook's Android SDK v4.0 (see changelog) you need to execute the following:

LoginManager.getInstance().logOut();

For Left indent Shift + Tab

For Right indent simple Tab

There is a good and regularly updated guide on how to set a new password for the latest MySQL.

https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-20-04

It would be best to read whole topic from the link above but in short, this maybe could help,

Run the security script:

sudo mysql_secure_installation

Detailed Info for "mysql_secure_installation"

After that, you can change password by following the next steps

sudo mysql

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'password';

Detailed Info for changin root user password

If you have a problem maybe you will need to reinstall MySql.

First find the condition that occurs in all situations, then filter the special conditions:

Fact 1: Projects and Repositories were always synonyms on GitHub.

Fact 2: This is no longer the case.

There is a lot of confusion about Repositories and Projects. In the past both terms were used pretty much interchangeably by the users and the GitHub's very own documentation. This is reflected by some of the answers and comments here that explain the subtle differences between those terms and when the one was preferred over the other. The difference were always subtle, e.g. like the issue tracker being part of the project but not part of the repository which might be thought of as a strictly git thing etc.

Not any more.

Currently repos and projects refer to a different kinds of entities that have separate APIs:

• https://developer.github.com/v3/repos/
• https://developer.github.com/v3/projects/

Since then it is no longer correct to call the repo a project or vice versa. Note that it is often confused in the official documentation and it is unfortunate that a term that was already widely used has been chosen as the name of the new entity but this is the case and we have to live with that.

The consequence is that repos and projects are usually confused and every time you read about GitHub projects you have to wonder if it's really about the projects or about repos. Had they chosen some other name or an abbreviation like "proj" then we could know that what is discussed is the new type of entity, a precise object with concrete properties, or a general speaking repo-like projectish kind of thingy.

The term that is usually unambiguous is "project board".

What can we learn from the API

The first endpoint in the documentation of the Projects API:

• https://developer.github.com/v3/projects/#list-repository-projects

is described as: List repository projects. It means that a repository can have many projects. So those two cannot mean the same thing. It includes Response if projects are disabled:

{
  "message": "Projects are disabled for this repo",
  "documentation_url": "https://developer.github.com/v3"
}

which means that some repos can have projects disabled. Again, those cannot be the same thing when a repo can have projects disabled.

There are some other interesting endpoints:

• Create a repository project - POST /repos/:owner/:repo/projects
• Create an organization project - POST /orgs/:org/projects

but there is no:

• Create a user's project - POST /users/:user/projects

Which leads us to another difference:

1. Repositories can belong to users or organizations
2. Projects can belong to repositories or organizations

or, more importantly:

1. Projects can belong to repositories but not the other way around
2. Projects can belong to organizations but not to users
3. Repositories can belong to organizations and to users

See also:

• https://help.github.com/articles/about-project-boards/

I know it's confusing. I tried to explain it as precisely as I could.

you have error in your code unexpected token.use:

  $('#purpose').on('change', function () {
   if (this.value == '1') {
    $("#business").show();
    } else {
    $("#business").hide();
   }

   });

Demo

Update: You can narrow down the code using .toggle()

 $('#purpose').on('change', function () {
   $("#business").toggle(this.value == '1');
 });

For example,

package verbose

import (
    "fmt"
    "testing"
)

func TestPrintSomething(t *testing.T) {
    fmt.Println("Say hi")
    t.Log("Say bye")
}

go test -v
=== RUN TestPrintSomething
Say hi
--- PASS: TestPrintSomething (0.00 seconds)
    v_test.go:10: Say bye
PASS
ok      so/v    0.002s

Command go

Description of testing flags

-v
Verbose output: log all tests as they are run. Also print all
text from Log and Logf calls even if the test succeeds.

Package testing

func (*T) Log

func (c *T) Log(args ...interface{})

Log formats its arguments using default formatting, analogous to Println, and records the text in the error log. For tests, the text will be printed only if the test fails or the -test.v flag is set. For benchmarks, the text is always printed to avoid having performance depend on the value of the -test.v flag.

You can do this inside your $.post calls success callback like this

$.post('mail.php',{name:$('#name').val(),
                              email:$('#e-mail').val(),
                              phone:$('#phone').val(),
                              message:$('#message').val()},

            //return the data
            function(data){

              //hide the graphic
              $('.bar').css({display:'none'});
              $('.loader').append(data);

              //clear fields
              $('input[type="text"],textarea').val('');

            });

Normally, IIS would use the process identity (the user account it is running the worker process as) to access protected resources like file system or network.

With passthrough authentication, IIS will attempt to use the actual identity of the user when accessing protected resources.

If the user is not authenticated, IIS will use the application pool identity instead. If pool identity is set to NetworkService or LocalSystem, the actual Windows account used is the computer account.

The IIS warning you see is not an error, it's just a warning. The actual check will be performed at execution time, and if it fails, it'll show up in the log.

Also, take a look at FrameLayout, that's how the Camera's Gallery application implements the Zoom buttons overlay.

You are not using a .NET control for your text area. Either add runat="server" to the HTML TextArea control or use a .NET control:

Try this:

<asp:TextBox id="TextArea1" TextMode="multiline" Columns="50" Rows="5" runat="server" />

Then reference it in your codebehind:

message.Body = TextArea1.Text;

From the command line:

psql -f 1.sql
psql -f 2.sql

From the psql prompt:

\i 1.sql
\i 2.sql

Note that you may need to import the files in a specific order (for example: data definition before data manipulation). If you've got bash shell (GNU/Linux, Mac OS X, Cygwin) and the files may be imported in the alphabetical order, you may use this command:

for f in *.sql ; do psql -f $f ; done

Here's the documentation of the psql application (thanks, Frank): http://www.postgresql.org/docs/current/static/app-psql.html

You would simply need to do this in your onClick:

AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Alert");
alertDialog.setMessage("Alert message to be shown");
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
alertDialog.show();

I don't know from where you saw that you need DialogFragment for simply showing an alert.

Hope this helps.

1. Go to Toolbar -> Settings -> Compiler
2. In the Selected compiler drop-down menu, make sure GNU GCC Compiler is selected
3. Below that, select the compiler settings tab and then the compiler flags tab underneath
4. In the list below, make sure the box for "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]" is checked
5. Click OK to save

For those who can't use a .dockerignore file (e.g. if you need the file in one COPY but not another):

Yes, but you need multiple COPY instructions. Specifically, you need a COPY for each letter in the filename you wish to exclude.

COPY [^n]*    # All files that don't start with 'n'
COPY n[^o]*   # All files that start with 'n', but not 'no'
COPY no[^d]*  # All files that start with 'no', but not 'nod'

Continuing until you have the full file name, or just the prefix you're reasonably sure won't have any other files.

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

We actually just upgraded a .NET web service to 4.6 to allow TLS 1.2.

What Artem is saying were the first steps we've done. We recompiled the framework of the web service to 4.6 and we tried change the registry key to enable TLS 1.2, although this didn't work: the connection was still in TLS 1.0. Also, we didn't want to disallow SLL 3.0, TLS 1.0 or TLS 1.1 on the machine: other web services could be using this; we rolled-back our changes on the registry.

We actually changed the Web.Config files to tell IIS: "hey, run me in 4.6 please".

Here's the changes we added in the web.config + recompilation in .NET 4.6:

<system.web>
    <compilation targetFramework="4.6"/> <!-- Changed framework 4.0 to 4.6 -->

    <!--Added this httpRuntime -->
    <httpRuntime targetFramework="4.6" />

    <authentication mode="Windows"/>
    <pages controlRenderingCompatibilityVersion="4.0"/>
</system.web>

And the connection changed to TLS 1.2, because IIS is now running the web service in 4.6 (told explicitly) and 4.6 is using TLS 1.2 by default.

you have to rename the column to an other name because TABLE is reserved by Oracle.

You can see all reserved words of Oracle in the oracle view V$RESERVED_WORDS.

you can have an interface hierarchy and then extend your classes from selected interfaces :

public interface IAnimal {
}

public interface IBird implements IAnimal {
}

public  interface IHorse implements IAnimal {
}

public interface IPegasus implements IBird,IHorse{
}

and then define your classes as needed, by extending a specific interface :

public class Bird implements IBird {
}

public class Horse implements IHorse{
}

public class Pegasus implements IPegasus {
}

In terms of bytecode, in saves a LOAD_ATTR and replaces a CALL_FUNCTION with a COMPARE_OP.

>>> dis.dis(indict)
  2           0 LOAD_GLOBAL              0 (name)
              3 LOAD_GLOBAL              1 (d)
              6 COMPARE_OP               6 (in)
              9 POP_TOP             


>>> dis.dis(haskey)
  2           0 LOAD_GLOBAL              0 (d)
              3 LOAD_ATTR                1 (haskey)
              6 LOAD_GLOBAL              2 (name)
              9 CALL_FUNCTION            1
             12 POP_TOP             

My feelings are that in is much more readable and is to be preferred in every case that I can think of.

In terms of performance, the timing reflects the opcode

$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "'foo' in d"
 10000000 loops, best of 3: 0.11 usec per loop

$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "d.has_key('foo')"
  1000000 loops, best of 3: 0.205 usec per loop

in is almost twice as fast.

from collections import OrderedDict
OrderedDict((word, True) for word in words)

contains

OrderedDict([('He', True), ('will', True), ('be', True), ('the', True), ('winner', True)])

If the values are True (or any other immutable object), you can also use:

OrderedDict.fromkeys(words, True)

Just a fyi for people enabling mod_rewrite on Debian with Apache2:

To check whether mod_rewrite is enabled:

Look in mods_enabled for a link to the module by running

ls /etc/apache2/mods-enabled | grep rewrite

If this outputs rewrite.load then the module is enabled. (Note: your path to apache2 may not be /etc/, though it's likely to be.)

To enable mod_rewrite if it's not already:

Enable the module (essentially creates the link we were looking for above):

a2enmod rewrite

Reload all apache config files:

service apache2 restart

Edit: After updating to appcompat-v7:22.1.1 and using AppCompatActivity instead of ActionBarActivity my styles.xml looks like:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Note: This means I am using a Toolbar provided by the framework (NOT included in an XML file).

This worked for me:
styles.xml file:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Update: A quote from Gabriele Mariotti's blog.

With the new Toolbar you can apply a style and a theme. They are different! The style is local to the Toolbar view, for example the background color. The app:theme is instead global to all ui elements inflated in the Toolbar, for example the color of the title and icons.

A note about 'throw()' mentioned above. It seems that it stops execution of the page completely (I checked in IE8) , so it's not very useful for logging "on going processes" (like to track a certain variable...)

My suggestion is perhaps to add a textarea element somewhere in your document and to change (or append to) its value (which would change its text) for logging information whenever needed...

We are currently using protobuf-java-format to convert our Protobuf messages (anything subclass of Message) into a JSON format to send over our web API.

Simply do:

  JsonFormat.printToString(protoMessage)

This's a jQuery free solution that can work with SPA inside the iframe

document.getElementById('iframe-id').addEventListener('load', function () {
  let that = this;
  setTimeout(function () {
    that.style.height = that.contentWindow.document.body.offsetHeight + 'px';
  }, 2000) // if you're having SPA framework (angularjs for example) inside the iframe, some delay is needed for the content to populate
});

process.stdin.pipe(process.stdout);

Using this approach with Response.js is better. Response.resize triggers on every window resize where crossover will only be triggered if breakpoint is changed

Response.create({
    prop : "width",
    breakpoints : [1200, 992, 768, 480, 320, 0]
});

Response.crossover('width', function() {
    if (Response.band(1200)) {
        // 1200+

    } else if (Response.band(992)) {
        // 992+

    } else if (Response.band(768)) {
        // 768+

    } else if (Response.band(480)) {
        //480+

    } else {
        // 0->320

    }
});

Response.ready(function() {
    $(window).trigger('resize');
});

var getKeyByDinner = function(obj, dinner) {
    var returnKey = -1;

    $.each(obj, function(key, info) {
        if (info.dinner == dinner) {
           returnKey = key;
           return false; 
        };   
    });

    return returnKey;       

}

jsFiddle.

So long as -1 isn't ever a valid key.

You should be able to do this via the command line arguments, assuming these are Sun VMs installed using the usual Windows InstallShield mechanisms with the JVM finder EXE in system32.

Type java -help for the options. In particular, see:

-version:<value>
              require the specified version to run
-jre-restrict-search | -jre-no-restrict-search
              include/exclude user private JREs in the version search

Crude, but does what you want, breaks the execution scope:

$(function(){
setTimeout(function(){
//Code to call
},1);
});

Wildcards aren't expanded inside quoted strings. And when wildcard is expanded, it's returned unchanged if there are no matches, it doesn't expand into an empty string. Try:

output="$(ls home/edward/bank1/fiche/Test* 2>/dev/null)"
if [ -n "$output" ]
then echo "Found one"
else echo "Found none"
fi

If the wildcard expanded to filenames, ls will list them on stdout; otherwise it will print an error on stderr, and nothing on stdout. The contents of stdout are assigned to output.

if [ -n "$output" ] tests whether $output contains anything.

Another way to write this would be:

if [ $(ls home/edward/bank1/fiche/Test* 2>/dev/null | wc -l) -gt 0 ]

The simplest approach would be to use any of these class utilities that Bootstrap provides:

<div class="position-fixed">...</div>
<div class="position-sticky">...</div>
<div class="fixed-top">...</div>
<div class="fixed-bottom">...</div>
<div class="sticky-top">...</div>

https://getbootstrap.com/docs/4.0/utilities/position

Or, to get a pseudo-random int in the range 0 to 19, for example, you could use the higher bits like this:

j = ((rand() >> 15) % 20;

If you have VS 2013, you have to go to: %LOCALAPPDATA%\Microsoft\VisualStudio\12.0 then rename the ComponentModelCache folder.

if you are outputting the code as html - change /n -->
and do echo $message;

In spark 2.2 there are two ways to add constant value in a column in DataFrame:

1) Using lit

2) Using typedLit.

The difference between the two is that typedLit can also handle parameterized scala types e.g. List, Seq, and Map

Sample DataFrame:

val df = spark.createDataFrame(Seq((0,"a"),(1,"b"),(2,"c"))).toDF("id", "col1")

+---+----+
| id|col1|
+---+----+
|  0|   a|
|  1|   b|
+---+----+

1) Using lit: Adding constant string value in new column named newcol:

import org.apache.spark.sql.functions.lit
val newdf = df.withColumn("newcol",lit("myval"))

Result:

+---+----+------+
| id|col1|newcol|
+---+----+------+
|  0|   a| myval|
|  1|   b| myval|
+---+----+------+

2) Using typedLit:

import org.apache.spark.sql.functions.typedLit
df.withColumn("newcol", typedLit(("sample", 10, .044)))

Result:

+---+----+-----------------+
| id|col1|           newcol|
+---+----+-----------------+
|  0|   a|[sample,10,0.044]|
|  1|   b|[sample,10,0.044]|
|  2|   c|[sample,10,0.044]|
+---+----+-----------------+

That code transforms any bootstrap table row that has data-href attribute set into a clickable element

Note: data-href attribute is a valid tr attribute (HTML5), href attributes on tr element are not.

$(function(){
    $('.table tr[data-href]').each(function(){
        $(this).css('cursor','pointer').hover(
            function(){ 
                $(this).addClass('active'); 
            },  
            function(){ 
                $(this).removeClass('active'); 
            }).click( function(){ 
                document.location = $(this).attr('data-href'); 
            }
        );
    });
});

Just to add to answers by Mr. Dimitrov and Jason, if you are using a specific profile and you have put your region setting there,then for all the requests you need to add

"--profile" option.

For example:

Lets say you have AWS Playground profile, and the ~/.aws/config has [profile playground] which further has something like,

[profile playground] region=us-east-1

then, use something like below

aws ecs list-container-instances --cluster default --profile playground

Java and Javascript are similar like Car and Carpet are similar.

Stack memory is specifically the range of memory that is accessible via the Stack register of the CPU. The Stack was used as a way to implement the "Jump-Subroutine"-"Return" code pattern in assembly language, and also as a means to implement hardware-level interrupt handling. For instance, during an interrupt, the Stack was used to store various CPU registers, including Status (which indicates the results of an operation) and Program Counter (where was the CPU in the program when the interrupt occurred).

Stack memory is very much the consequence of usual CPU design. The speed of its allocation/deallocation is fast because it is strictly a last-in/first-out design. It is a simple matter of a move operation and a decrement/increment operation on the Stack register.

Heap memory was simply the memory that was left over after the program was loaded and the Stack memory was allocated. It may (or may not) include global variable space (it's a matter of convention).

Modern pre-emptive multitasking OS's with virtual memory and memory-mapped devices make the actual situation more complicated, but that's Stack vs Heap in a nutshell.

go to Services, find SQL Server Browser, right click --> Properties --> General tab --> Startup Type --> select automatic . Then go back to configuration management, start it.

Simply:

data$rownumber = 1:nrow(Data)

If you are talking about sed, this works:

sed -e "s/ /,/g" < a.txt

In vim, use same regex to replace:

s/ /,/g

There are plenty of descriptive answers here so I'm not going to repeat what has already been said. What I would like to add is the following code demonstrating all the permutations I can think of. The code is quite long due to the number of combinations. Feel free to drop it into MSTest and see the output for yourself (the output is included at the bottom).

This evidence supports Jon Skeet's answer.

Code:

[TestMethod]
public void StringEqualsMethodVsOperator()
{
    string s1 = new StringBuilder("string").ToString();
    string s2 = new StringBuilder("string").ToString();

    Debug.WriteLine("string a = \"string\";");
    Debug.WriteLine("string b = \"string\";");

    TryAllStringComparisons(s1, s2);

    s1 = null;
    s2 = null;

    Debug.WriteLine(string.Join(string.Empty, Enumerable.Repeat("-", 20)));
    Debug.WriteLine(string.Empty);
    Debug.WriteLine("string a = null;");
    Debug.WriteLine("string b = null;");

    TryAllStringComparisons(s1, s2);
}
private void TryAllStringComparisons(string s1, string s2)
{
    Debug.WriteLine(string.Empty);
    Debug.WriteLine("-- string.Equals --");
    Debug.WriteLine(string.Empty);
    Try((a, b) => string.Equals(a, b), s1, s2);
    Try((a, b) => string.Equals((object)a, b), s1, s2);

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

you can define attribute selected="selected" in Ex a

You can achieve your desired through easily by CSS :-

HTML

<input type="submit" name="submit" value="Submit Application" id="submit" />

CSS

#submit {

    -webkit-border-radius: 5px;
    border-radius:6px;
    color: #fff;
    font-family: 'Oswald';
    font-size: 20px;

This has support for both title and image.

For iOS 11 and afterwards:

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let action = UIContextualAction(
        style: .normal,
        title: "My Title",
        handler: { (action, view, completion) in
            //do what you want here
            completion(true)
    })

    action.image = UIImage(named: "My Image")
    action.backgroundColor = .red
    let configuration = UISwipeActionsConfiguration(actions: [action])
    configuration.performsFirstActionWithFullSwipe = false
    return configuration
}

Also, similar method is available for leadingSwipeActions

I have two methods to detect WIFI connection receiving the application context:

1)my old method

public boolean isConnectedWifi1(Context context) {
    try {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();           
        if (networkInfo != null) {
            NetworkInfo[] netInfo = connectivityManager.getAllNetworkInfo();
            for (NetworkInfo ni : netInfo) {
                if ((ni.getTypeName().equalsIgnoreCase("WIFI"))
                        && ni.isConnected()) {
                    return true;
                }                   
            }
        }
        return false;
    } catch (Exception e) {
        Log.e(TAG, e.getMessage());
    }
    return false;
}

2)my New method (I´m currently using this method):

public boolean isConnectedWifi(Context context) {
         ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
         NetworkInfo networkInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);     
         return networkInfo.isConnected();
}

New-style classes have an mro method you can call which returns a list of parent classes in method resolution order.

A jar file is simply a file containing a collection of java files. To make a jar file executable, you need to specify where the main Class is in the jar file. Example code would be as follows.

public class JarExample {

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                // your logic here
            }
        });
    }
}

Compile your classes. To make a jar, you also need to create a Manifest File (MANIFEST.MF). For example,

Manifest-Version: 1.0
Main-Class: JarExample

Place the compiled output class files (JarExample.class,JarExample$1.class) and the manifest file in the same folder. In the command prompt, go to the folder where your files placed, and create the jar using jar command. For example (if you name your manifest file as jexample.mf)

jar cfm jarexample.jar jexample.mf *.class

It will create executable jarexample.jar.

You can just use

explorer "https://google.com"

Which will launch your default browser and navigate to that site.

And on Mac I've using

open "https://google.com"

This link will help you in understanding pass by reference in C#. Basically,when an object of reference type is passed by value to an method, only methods which are available on that object can modify the contents of object.

For example List.sort() method changes List contents but if you assign some other object to same variable, that assignment is local to that method. That is why myList remains unchanged.

If we pass object of reference type by using ref keyword then we can assign some other object to same variable and that changes entire object itself.

(Edit: this is the updated version of the documentation linked above.)

When setting with JQM, don't forget to update the UI:

$('#selectId').val('newValue').selectmenu('refresh', true);

It looks like the Django REST framework uses the HTTP accept header in a Request in order to automatically determine which renderer to use:

http://www.django-rest-framework.org/api-guide/renderers/

Using the HTTP accept header may provide an alternative source for your "if something".

Subtract 2 to it recursively until you reach either -1 or 0 (only works for positive integers obviously) :)

There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..

At the very simplest, you would catch urllib2.URLError:

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    raise MyException("There was an error: %r" % e)

The following should capture the specific error raised when the connection times out:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    # For Python 2.6
    if isinstance(e.reason, socket.timeout):
        raise MyException("There was an error: %r" % e)
    else:
        # reraise the original error
        raise
except socket.timeout, e:
    # For Python 2.7
    raise MyException("There was an error: %r" % e)

The way you use the csv module changed in Python 3 in several respects (docs), at least with respect to how you need to open the file. Anyway, something like

import csv
with open('test.csv', 'w', newline='') as fp:
    a = csv.writer(fp, delimiter=',')
    data = [['Me', 'You'],
            ['293', '219'],
            ['54', '13']]
    a.writerows(data)

should work.

Just replace following line

exec -a "$0" "$HERE/chrome" "$@"

with

exec -a "$0" "$HERE/chrome" "$@" --user-data-dir 

all things will be right.

new Guid(string)

You could also look at using a TypeConverter.

Create your partial view something like:

@model YourModelType
<div>
  <!-- HTML to render your object -->
</div>

Then in your view use:

@Html.Partial("YourPartialViewName", Model)

If you do not want a strongly typed partial view remove the @model YourModelType from the top of the partial view and it will default to a dynamic type.

Update

The default view engine will search for partial views in the same folder as the view calling the partial and then in the ~/Views/Shared folder. If your partial is located in a different folder then you need to use the full path. Note the use of ~/ in the path below.

@Html.Partial("~/Views/Partials/SeachResult.cshtml", Model)

I know this is an old thread, but none of the other answers fully solved my use case (I guess Guava Multiset might do the same, but there is no example here). Please excuse my formatting. I am still new to posting on stack exchange. Additionally let me know if there are any errors

Lets say you have List<T> a and List<T> b and you want to check if they are equal with the following conditions:

1) O(n) expected running time
2) Equality is defined as: For all elements in a or b, the number of times the element occurs in a is equal to the number of times the element occurs in b. Element equality is defined as T.equals()

private boolean listsAreEquivelent(List<? extends Object> a, List<? extends Object> b) {
    if(a==null) {
        if(b==null) {
            //Here 2 null lists are equivelent. You may want to change this.
            return true;
        } else {
            return false;
        }
    }
    if(b==null) {
        return false;
    }
    Map<Object, Integer> tempMap = new HashMap<>();
    for(Object element : a) {
        Integer currentCount = tempMap.get(element);
        if(currentCount == null) {
            tempMap.put(element, 1);
        } else {
            tempMap.put(element, currentCount+1);
        }
    }
    for(Object element : b) {
        Integer currentCount = tempMap.get(element);
        if(currentCount == null) {
            return false;
        } else {
            tempMap.put(element, currentCount-1);
        }
    }
    for(Integer count : tempMap.values()) {
        if(count != 0) {
            return false;
        }
    }
    return true;
}

Running time is O(n) because we are doing O(2*n) insertions into a hashmap and O(3*n) hashmap selects. I have not fully tested this code, so beware :)

//Returns true:
listsAreEquivelent(Arrays.asList("A","A","B"),Arrays.asList("B","A","A"));
listsAreEquivelent(null,null);
//Returns false:
listsAreEquivelent(Arrays.asList("A","A","B"),Arrays.asList("B","A","B"));
listsAreEquivelent(Arrays.asList("A","A","B"),Arrays.asList("A","B"));
listsAreEquivelent(Arrays.asList("A","A","B"),null);

Remember to look if your column can be null. You can do that using

mysql> desc my_table;

If your column cannot be null, when you set the value to null it will be the cast value to it.

Here a example

mysql> create table example ( age int not null, name varchar(100) not null );
mysql> insert into example values ( null, "without num" ), ( 2 , null );
mysql> select * from example;
+-----+-------------+
| age | name        |
+-----+-------------+
|   0 | without num |
|   2 |             |
+-----+-------------+
2 rows in set (0.00 sec)

mysql> select * from example where age is null or name is null;
Empty set (0.00 sec)

When looking for a large amount of key words in a document, use flashtext

from flashtext import KeywordProcessor
words = ['test', 'exam', 'quiz']
txt = 'this is a test'
kwp = KeywordProcessor()
kwp.add_keywords_from_list(words)
result = kwp.extract_keywords(txt, span_info=True)

Flashtext runs faster than regex on large list of search words.

obj is an array in your example.

fs.writeFileSync(filename, data, [options]) requires either String or Buffer in the data parameter. see docs.

Try to write the array in a string format:

// writes 'https://twitter.com/#!/101Cookbooks', 'http://www.facebook.com/101cookbooks'
fs.writeFileSync('./data.json', obj.join(',') , 'utf-8'); 

Or:

// writes ['https://twitter.com/#!/101Cookbooks', 'http://www.facebook.com/101cookbooks']
var util = require('util');
fs.writeFileSync('./data.json', util.inspect(obj) , 'utf-8');

edit: The reason you see the array in your example is because node's implementation of console.log doesn't just call toString, it calls util.format see console.js source

String.split implementations will have serious limitations if the data in a tab-delimited field itself contains newline, tab and possibly " characters.

TAB-delimited formats have been around for donkey's years, but format is not standardised and varies. Many implementations don't escape characters (newlines and tabs) appearing within a field. Rather, they follow CSV conventions and wrap any non-trivial fields in "double quotes". Then they escape only double-quotes. So a "line" could extend over multiple lines.

Reading around I heard "just reuse apache tools", which sounds like good advice.

In the end I personally chose opencsv. I found it light-weight, and since it provides options for escape and quote characters it should cover most popular comma- and tab- delimited data formats.

Example:

CSVReader tabFormatReader = new CSVReader(new FileReader("yourfile.tsv"), '\t');

It's just the wrong order

var e = $('<div style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');

e.attr('id', 'myid');

Append first and then access/set attr.

This issue arises when the host key is expired or changed. you can remove the keys that host is using and try to ssh again, so that you are adding new key that is known to both client and server.

You can check the keys associated with your hosts with cat /.ssh/known_hosts . Now, You can remove the hosts keys manually or using the ssh-keygen option. You can do either of the following option.

1. Manual removal of keys

   vim /.ssh/known_hosts

delete the key that is associated with your host.

2. Remove key using ssh-keygen

   ssh-keygen -R your_host_or_host_ip

This will remove your key associated with the host.

Now, you can ssh to your host as usual and you will be asked if you want to continue to this host. Once your enter yes, this host will be added to your/.ssh/known_hosts with updated key. By now, you should be your host.

The accepted answer makes you believe that you must use a class or a std::function as comparator. This is not true! As cute_ptr's answer shows, you can pass a function pointer to the constructor. However, the syntax to do so is much simpler than shown there:

class Node;
bool Compare(Node a, Node b);

std::priority_queue<Node, std::vector<Node>, decltype(&Compare)> openSet(Compare);

That is, there is no need to explicitly encode the function's type, you can let the compiler do that for you using decltype.

This is very useful if the comparator is a lambda. You cannot specify the type of a lambda in any other way than using decltype. For example:

auto compare = [](Node a, Node b) { return a.foo < b.foo; }
std::priority_queue<Node, std::vector<Node>, decltype(compare)> openSet(compare);

You can use display:inline-block to force this behavior

Yes you can (this is how I understand the original question). Here is how I did it. Just tie it into outside context. For example:

//javascript

my_function = null;

//jquery 
 $(function() { 

        function my_fun(){ 
               /.. some operations ../ 
        }  
        my_function = my_fun;
 }) 

 //just js 
 function js_fun () {  
       my_function(); //== call jquery function - just Reference is globally defined not function itself
}

I encountered this same problem when trying to access methods of the object, that was instantiated on DOM object ready only. Works. My example:

MyControl.prototype = {
   init:   function { 
        // init something
   }
   update: function () {
           // something useful, like updating the list items of control or etc.         
   }
}

MyCtrl = null;

// create jquery plug-in
$.fn.aControl = function () {
    var control = new MyControl(this);
    control.init();
    MyCtrl = control; // here is the trick
    return control;
}

now you can use something simple like:

function() = {
   MyCtrl.update(); // yes!
}

$('#thisElement').find('.classToSelect') will find any descendents of #thisElement with class classToSelect.

Check with your host to see if they have any hourly limits to emails being sent.

Although there is no need to close the file manually but it is good idea to do so if the scope of the file variable is bigger:

    ifstream infile(szFilePath);

    for (string line = ""; getline(infile, line); )
    {
        //do something with the line
    }

    if(infile.is_open())
        infile.close();

Because they have different meanings. The @Transient annotation tells the JPA provider to not persist any (non-transient) attribute. The other tells the serialization framework to not serialize an attribute. You might want to have a @Transient property and still serialize it.

In the Nuget package of SQLLite Core there is a the file System.Data.SQLite.Core.targets . Just include this in all projects that use the this library and all libraries that used your library.

In yours .csproj or .vbproj files add: Every time you compile in your bin will added x86 and x64 directory with the SQLite.Interop.dll file.

I faced the same problem. Renaming the file worked for me.

It is called an interface. Many OO languages have this feature. You might want to read through the php explanation here: http://de2.php.net/interface

From Oracle 12c R2 you could use COLLATE operator:

The COLLATE operator determines the collation for an expression. This operator enables you to override the collation that the database would have derived for the expression using standard collation derivation rules.

The COLLATE operator takes one argument, collation_name, for which you can specify a named collation or pseudo-collation. If the collation name contains a space, then you must enclose the name in double quotation marks.

Demo:

CREATE TABLE tab1(i INT PRIMARY KEY, name VARCHAR2(100));

INSERT INTO tab1(i, name) VALUES (2, 'Joe');
INSERT INTO tab1(i, name) VALUES (3, 'Billy');

Here's what I did:

• Extracted the files using WinRAR
• Made my changes to the extracted files
• Opened the original JAR file with WinRAR
• Used the ADD button to replace the files that I modified

That's it. I have tested it with my Nokia and it's working for me.

You can also run the follow command to reset the query cache.

RESET QUERY CACHE

So I install MinGW and tack that on the install line as the compiler of choice. But then I get the error "RuntimeError: chmod error".

You need to install msys package under MinGW

and add following entries in your PATH env variable.

• C:\MinGW\bin
• C:\MinGW\msys\1.0\bin [This is where you will find chmod executable]

Then run your command from normal windows command prompt.

Made some changes, but I think I got the effect you want using visibility. http://jsfiddle.net/9dsGP/49/

I also made these changes:

position: absolute; /* so it doesn't expand the button background */
top: calc(1em + 8px); /* so it's under the "button" */
left:8px; /* so it's shifted by padding-left */
width: 182px; /* so it fits nicely under the button, width - padding-left - padding-right - border-left-width - border-right-width, 200 - 8 - 8 - 1 - 1 = 182 */

Alternatively, you could put .content as a sibling of .button, but I didn't make an example for this.

This is only a warning: your code still works, but probably won't work in the future as the method is deprecated. See the relevant source of Chromium and corresponding patch.

This has already been recognised and fixed in jQuery 1.11 (see here and here).

echo off
setlocal
SET AREYOUSURE = N
:PROMPT
set /P AREYOUSURE=Update Release Files (Y/N)?
if /I %AREYOUSURE% NEQ Y GOTO END
set /P AREYOUSURE=Are You Sure you want to Update Release Files (Y/N)?
if /I %AREYOUSURE% NEQ Y GOTO END

echo Copying New Files

:END

This is code I use regularly. I have noticed in the examples in this blog that quotes are used. If the test line is changed to use quotes the test is invalid.

if /I %AREYOUSURE% NEQ "Y" GOTO END

I have tested on XP, Vista, Win7 and Win8. All fail when quotes are used.

You can iterate over a dictionary and grab an index with for-in and enumerate (like others have said, there is no guarantee it will come out ordered like below)

let dict = ["c": 123, "d": 045, "a": 456]

for (index, entry) in enumerate(dict) {
    println(index)   // 0       1        2
    println(entry)   // (d, 45) (c, 123) (a, 456)
}

If you want to sort first..

var sortedKeysArray = sorted(dict) { $0.0 < $1.0 }
println(sortedKeysArray)   // [(a, 456), (c, 123), (d, 45)]

var sortedValuesArray = sorted(dict) { $0.1 < $1.1 }
println(sortedValuesArray) // [(d, 45), (c, 123), (a, 456)]

then iterate.

for (index, entry) in enumerate(sortedKeysArray) {
    println(index)    // 0   1   2
    println(entry.0)  // a   c   d
    println(entry.1)  // 456 123 45
}

If you want to create an ordered dictionary, you should look into Generics.

It seem that w3c switched it to font/woff2

I see there is some discussion about the proper mime type. In the link we read:

This document defines a top-level MIME type "font" ...

... the officially defined IANA subtypes such as "application/font-woff" ...

The members of the W3C WebFonts WG believe the use of "application" top-level type is not ideal.

and later

6.5. WOFF 2.0

    Type name:

        font
    Subtype name:

        woff2

So proposition from W3C differs from IANA.

We can see that it also differs from woff type: http://dev.w3.org/webfonts/WOFF/spec/#IMT where we read:

Type name:

    application
Subtype name:

    font-woff

which is

application/font-woff

http://www.w3.org/TR/WOFF/#appendix-b

The first is a constant pointer to a char and the second is a pointer to a constant char. You didn't touch all the cases in your code:

char * const pc1 = &a; /* You can't make pc1 point to anything else */
const char * pc2 = &a; /* You can't dereference pc2 to write. */

*pc1 = 'c' /* Legal. */
*pc2 = 'c' /* Illegal. */

pc1 = &b; /* Illegal, pc1 is a constant pointer. */
pc2 = &b; /* Legal, pc2 itself is not constant. */

It is just such simple as writing:

$('input[type=file]').val()

Anyway, I suggest using name or ID attribute to select your input. And with event, it should look like this:

$('input[type=file]').change(function(e){
  $in=$(this);
  $in.next().html($in.val());
});

Swift 3

webView.scrollView.bounces = false

Your concatenation syntax is correct.

Most likely the callback function isn't even being called. You can test that by putting an alert(), console.log() or debugger line in that function.

If it isn't being called, most likely there's an AJAX error. Look at chaining a .fail() handler after $.post() to find out what the error is, e.g.:

$.post('ajaxskeleton.php', {
    red: text       
}, function(){
    $('#part' + number).html(text);
}).fail(function(jqXHR, textStatus, errorThrown) {
    console.log(arguments);
});

WAMP server generally provide addond for different php/mysql versions. However you mentioned you have downloaded latest wamp server. As of now, latest Wamp server v2.5 provide PHP version 5.5.12

So you need to upgrade it manually as follow:

1. Download binaries on php.net
2. Extract all files in a new folder : C:/wamp/bin/php/php5.5.27/
3. Copy the wampserver.conf from another php folder (like php/php5.5.12/) to the new folder
4. Rename php.ini-development file to phpForApache.ini
5. Done ! Restart WampServer (>Right Mouseclick on trayicon >Exit)

Although not asked, I'd recommend to vagrant/puppet or docker for local development. Check puphpet.com for details. It has slight learning curve but it will give you much better control of different versions of every tool.

Try run mysqladmin reload, which is located in /usr/loca/mysql/bin/ on mac.

1. In the loop you are assigning value rather than comparing value so

i=((Main.size())-1) -> i=(-1) since Main.size()

Main[i] will yield "Vector Subscript out of Range" coz i = -1.

2. You get Main.size() as 0 maybe becuase its not it can't find the file. Give the file path and check the output. Also it would be good to initialize the variables.

For a VB or C# app, one way to do this is by using Office Interop. This depends on which version of Excel you're working with.

For Excel 2003, this MSDN article is a good place to start. Understanding the Excel Object Model from a Visual Studio 2005 Developer's Perspective

You'll basically need to do the following:

• Start the Excel application.
• Open the Excel workbook.
• Retrieve the worksheet from the workbook by name or index.
• Iterate through all the Cells in the worksheet which were retrieved as a range.
• Sample (untested) code excerpt below for the last step.

    Excel.Range allCellsRng;
    string lowerRightCell = "IV65536";
    allCellsRng = ws.get_Range("A1", lowerRightCell).Cells;
    foreach (Range cell in allCellsRng)
    {
        if (null == cell.Value2 || isBlank(cell.Value2))
        {
          // Do something.
        }
        else if (isText(cell.Value2))
        {
          // Do something.
        }
        else if (isNumeric(cell.Value2))
        {
          // Do something.
        }
    }

For Excel 2007, try this MSDN reference.

No, the only thing that needs to be modified for an Anaconda environment is the PATH (so that it gets the right Python from the environment bin/ directory, or Scripts\ on Windows).

The way Anaconda environments work is that they hard link everything that is installed into the environment. For all intents and purposes, this means that each environment is a completely separate installation of Python and all the packages. By using hard links, this is done efficiently. Thus, there's no need to mess with PYTHONPATH because the Python binary in the environment already searches the site-packages in the environment, and the lib of the environment, and so on.

I had a similar requirement in the app I am working on. And, I found a third-party library which does a slide-up, slide-down and slide-right in Android.

Refer to the link for more details: https://github.com/mancj/SlideUp-Android

To set up the library(copied from the ReadMe portion of its Github page on request):

Get SlideUp library

Add the JitPack repository to your build file. Add it in your root build.gradle at the end of repositories:

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
    maven { url "https://maven.google.com" } // or google() in AS 3.0
  }
}

Add the dependency (in the Module gradle)

dependencies {
    compile 'com.github.mancj:SlideUp-Android:2.2.1'
    compile 'ru.ztrap:RxSlideUp2:2.x.x' //optional, for reactive listeners based on RxJava-2
    compile 'ru.ztrap:RxSlideUp:1.x.x' //optional, for reactive listeners based on RxJava
}

To add the SlideUp into your project, follow these three simple steps:

Step 1:

create any type of layout

<LinearLayout
  android:id="@+id/slideView"
  android:layout_width="match_parent"
  android:layout_height="match_parent"/>

Step 2:

Find that view in your activity/fragment

View slideView = findViewById(R.id.slideView);

Step 3:

Create a SlideUp object and pass in your view

slideUp = new SlideUpBuilder(slideView)
                .withStartState(SlideUp.State.HIDDEN)
                .withStartGravity(Gravity.BOTTOM)

                //.withSlideFromOtherView(anotherView)
                //.withGesturesEnabled()
                //.withHideSoftInputWhenDisplayed()
                //.withInterpolator()
                //.withAutoSlideDuration()
                //.withLoggingEnabled()
                //.withTouchableAreaPx()
                //.withTouchableAreaDp()
                //.withListeners()
                //.withSavedState()
                .build();

You may also refer to the sample project on the link. I found it quite useful.

add a repository,

sudo apt-add-repository ppa:maarten-fonville/android-studio
sudo apt-get update

Then install using the command below:

sudo apt-get install android-studio

Tested!

In Windows -> control panel -> Region -> Additional Settings -> Time -> Short Time:

Format your time as HH:mm

in the format

hh = 12 hours

HH = 24 hours

mm = minutes

tt = AM or PM

so to get the required result the format should be HH:mm and not hh:mm tt

Latest stuff with getMapAsync instead of the deprecated one.

1. check manifest for

<meta-data android:name="com.google.android.geo.API_KEY" android:value="xxxxxxxxxxxxxxxxxxxxxxxxx"/>

You can get the API Key for your app by registering your app at Google Cloud Console. Register your app as Native Android App

2. in your fragment layout .xml add FrameLayout(not fragment):

                  <FrameLayout
                android:layout_width="match_parent"
                android:layout_height="250dp"
                android:layout_weight="2"
                android:name="com.google.android.gms.maps.SupportMapFragment"
                android:id="@+id/mapwhere" />

or whatever height you want

3. In onCreateView in your fragment

    private SupportMapFragment mSupportMapFragment; 

    mSupportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.mapwhere);
    if (mSupportMapFragment == null) {
        FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        mSupportMapFragment = SupportMapFragment.newInstance();
        fragmentTransaction.replace(R.id.mapwhere, mSupportMapFragment).commit();
    }

    if (mSupportMapFragment != null)
    {
        mSupportMapFragment.getMapAsync(new OnMapReadyCallback() {
            @Override public void onMapReady(GoogleMap googleMap) {
                if (googleMap != null) {

                    googleMap.getUiSettings().setAllGesturesEnabled(true);

                      -> marker_latlng // MAKE THIS WHATEVER YOU WANT

                        CameraPosition cameraPosition = new CameraPosition.Builder().target(marker_latlng).zoom(15.0f).build();
                        CameraUpdate cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition);
                        googleMap.moveCamera(cameraUpdate);

                }

            }
        });

Another simple version working on PC:

Sub CreateDir(strPath As String)
    Dim elm As Variant
    Dim strCheckPath As String

    strCheckPath = ""
    For Each elm In Split(strPath, "\")
        strCheckPath = strCheckPath & elm & "\"
        If Len(Dir(strCheckPath, vbDirectory)) = 0 Then MkDir strCheckPath
    Next
End Sub

Sure, Xcode->Preferences and turn on Show line numbers.

This will print out boolean value as it is, instead of 1/0.

    $bool = false;

    echo json_encode($bool);   //false

There is another option to scroll page to required element if element has "id" attribute

If you want to navigate to page and scroll down to element with @id, it can be done automatically by adding #element_id to URL...

Example

Let's say we need to navigate to Selenium Waits documentation and scroll page down to "Implicit Wait" section. We can do

driver.get('https://selenium-python.readthedocs.io/waits.html')

and add code for scrolling...OR use

driver.get('https://selenium-python.readthedocs.io/waits.html#implicit-waits')

to navigate to page AND scroll page automatically to element with id="implicit-waits" (<div class="section" id="implicit-waits">...</div>)

<div id="item">show taille height</div>
<script>
    alert(document.getElementById('item').offsetHeight);
</script>

Jsfiddle

$hasDuplicates = count($array) > count(array_unique($array)); 

Will be true if duplicates, or false if no duplicates.

In the connection properties window I changed my selection from "SID" to "Service Name", and copied my SID into the Service Name field. No idea why this change happened or why it worked, but it got me back on Oracle.

String path = "C:\\Documents and Settings\\Manoj\\Desktop";
path = path.replace("\\", "/");
// or
path = path.replaceAll("\\\\", "/");

Find more details in the Docs

I don't know why all the answers over here are so confusing. I found a quite simpler one. Use a css class for the asp:menu, say, mainMenu and all the menu items under this will be "a tags" when rendered into HTML. So you just have to provide :hover property to those "a tags" in your CSS. See below for the example:

<asp:Menu ID="mnuMain" Orientation="Horizontal" runat="server" Font-Bold="True" Width="100%" CssClass="mainMenu">
  <Items>
    <asp:MenuItem Text="Home"></asp:MenuItem>
    <asp:MenuItem Text="About Us"></asp:MenuItem>
  </Items>
</asp:Menu>

And in the CSS, write:

.mainMenu { background:#900; }
.mainMenu a { color:#fff; }
.mainMenu a:hover { background:#c00; color:#ff9; }

I hope this helps. :)

The DISTINCT keyword doesn't really work the way you're expecting it to. When you use SELECT DISTINCT col1, col2, col3 you are in fact selecting all unique {col1, col2, col3} tuples.

Addition and subtraction in two's complement is the same for signed and unsigned numbers

The key observation is that CMP is basically subtraction, and:

In two's complement (integer representation used by x86), signed and unsigned addition are exactly the same operation

This allows for example hardware developers to implement it more efficiently with just one circuit.

So when you give input bytes to the x86 ADD instruction for example, it does not care if they are signed or not.

However, ADD does set a few flags depending on what happened during the operation:

• carry: unsigned addition or subtraction result does not fit in bit size, e.g.: 0xFF + 0x01 or 0x00 - 0x01

  For addition, we would need to carry 1 to the next level.

• sign: result has top bit set. I.e.: is negative if interpreted as signed.

• overflow: input top bits are both 0 and 0 or 1 and 1 and output inverted is the opposite.

  I.e. signed operation changed sigedness in an impossible way (e.g. positive + positive or negative

We can then interpret those flags in a way that makes comparison match our expectations for signed or unsigned numbers.

This interpretation is exactly what JA vs JG and JB vs JL do for us!

Code example

Here is GNU GAS a code snippet to make this more concrete:

/* 0x0 ==
 *
 * * 0 in 2's complement signed
 * * 0 in 2's complement unsigned
 */
mov $0, %al

/* 0xFF ==
 *
 * *  -1 in 2's complement signed
 * * 255 in 2's complement unsigned
 */
mov $0xFF, %bl

/* Do the operation "Is al < bl?" */
cmp %bl, %al

Note that AT&T syntax is "backwards": mov src, dst. So you have to mentally reverse the operands for the condition codes to make sense with cmp. In Intel syntax, this would be cmp al, bl

After this point, the following jumps would be taken:

• JB, because 0 < 255
• JNA, because !(0 > 255)
• JNL, because !(0 < -1)
• JG, because 0 > -1

Note how in this particular example the signedness mattered, e.g. JB is taken but not JL.

Runnable example with assertions.

Equals / Negated versions like JLE / JNG are just aliases

By looking at the Intel 64 and IA-32 Architectures Software Developer's Manuals Volume 2 section "Jcc - Jump if Condition Is Met" we see that the encodings are identical, for example:

Opcode  Instruction  Description
7E cb   JLE rel8     Jump short if less or equal (ZF=1 or SF ? OF).
7E cb   JNG rel8     Jump short if not greater (ZF=1 or SF ? OF).

var defaultsettings = {
    ajaxsettings: {
        ...
    },
    uisettings: {
        ...
    }
};

See this function

def parse_int(s):
    try:
        res = int(eval(str(s)))
        if type(res) == int:
            return res
    except:
        return

Then

val = parse_int('10')  # Return 10
val = parse_int('0')  # Return 0
val = parse_int('10.5')  # Return 10
val = parse_int('0.0')  # Return 0
val = parse_int('Ten')  # Return None

You can also check

if val == None:  # True if input value can not be converted
    pass  # Note: Don't use 'if not val:'

iOS
For an iOS app, in Swift 3, 4 or 5:

theImageView.image = theImageView.image?.withRenderingMode(.alwaysTemplate)
theImageView.tintColor = UIColor.red

For Swift 2:

theImageView.image = theImageView.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
theImageView.tintColor = UIColor.redColor()

Meanwhile, the modern Objective-C solution is:

theImageView.image = [theImageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[theImageView setTintColor:[UIColor redColor]];

Watchkit
In WatchKit for Apple Watch apps, you can set the tint color for a template image.

1. You must add your image to an Asset Catalog in your WatchKit App, and set the image set to be rendered as a Template Image in the Attributes Inspector. Unlike for an iPhone app, you cannot set the template rendering in code in the WatchKit Extension at present.
2. Set that image to be used in your WKInterfaceImage in interface builder for your app
3. Create an IBOutlet in your WKInterfaceController for the WKInterfaceImage called 'theImage'...

To then set the tint color in Swift 3 or 4:

theImage.setTintColor(UIColor.red)

Swift 2:

theImage.setTintColor(UIColor.redColor())

To then set the tint color in Objective-C:

[self.theImage setTintColor:[UIColor redColor]];

If you use a template image and do not apply a tint colour, the Global Tint for your WatchKit app will be applied. If you have not set a Global Tint, theImage will be tinted light blue by default when used as a template image.

Yes ..it is possible using INSERT ON DUPLICATE KEY UPDATE sql statement.. syntax: INSERT INTO table_name (a,b,c) VALUES (1,2,3),(4,5,6) ON DUPLICATE KEY UPDATE a=VALUES(a),b=VALUES(b),c=VALUES(c)

The following worked for me:

1. run VBoxManage internalcommands sethduuid "VDI/VMDK file" twice (the first time is just to conveniently generate an UUID, you could use any other UUID generation method instead)

2. open the .vbox file in a text editor

3. replace the UUID found in Machine uuid="{...}" with the UUID you got when you ran sethduuid the first time

4. replace the UUID found in HardDisk uuid="{...}" and in Image uuid="{}" (towards the end) with the UUID you got when you ran sethduuid the second time

if you have no systemctl and started the docker daemon by:

sudo service docker start

you can stop it by:

sudo service docker stop
