I'm also facing the same issue, for your android studio, you just change the android Gradle plugin version 3.3.2 and Gradle version is 5.1.1

Use .map without return in simple way. Also start using let and const instead of var because let and const is more recommended

const rockets = [_x000D_
    { country:'Russia', launches:32 },_x000D_
    { country:'US', launches:23 },_x000D_
    { country:'China', launches:16 },_x000D_
    { country:'Europe(ESA)', launches:7 },_x000D_
    { country:'India', launches:4 },_x000D_
    { country:'Japan', launches:3 }_x000D_
];_x000D_
_x000D_
const launchOptimistic = rockets.map(elem => (_x000D_
  {_x000D_
    country: elem.country,_x000D_
    launches: elem.launches+10_x000D_
  } _x000D_
));_x000D_
_x000D_
console.log(launchOptimistic);

Try the below steps:

npm uninstall webpack --save-dev

followed by

npm install [email protected] --save-dev

Then you should be able to gulp again. Fixed the issue for me.

For those receiving this warning for the first time, it is due to a bleeding edge feature called Passive Event Listeners that has been implemented in browsers fairly recently (summer 2016). From https://github.com/WICG/EventListenerOptions/blob/gh-pages/explainer.md:

Passive event listeners are a new feature in the DOM spec that enable developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners. Developers can annotate touch and wheel listeners with {passive: true} to indicate that they will never invoke preventDefault. This feature shipped in Chrome 51, Firefox 49 and landed in WebKit. For full official explanation read more here.

See also: What are passive event listeners?

You may have to wait for your .js library to implement support.

If you are handling events indirectly via a JavaScript library, you may be at the mercy of that particular library's support for the feature. As of December 2019, it does not look like any of the major libraries have implemented support. Some examples:

• jQuery.js - ongoing issue: https://github.com/jquery/jquery/issues/2871
• React.js - ongoing issue: https://github.com/facebook/react/issues/6436
• Hammer.js - closed due to no follow up: https://github.com/hammerjs/hammer.js/pull/987
• perfect-scrollbar - closed: https://github.com/noraesae/perfect-scrollbar/issues/560
• AngularJS - closed due to won't fix: https://github.com/angular/angular.js/issues/15901

If you are able to read the excel file correctly and only the integer values are not showing up. you can specify like this.

df = pd.read_excel('my.xlsx',sheetname='Sheet1', engine="openpyxl", dtype=str)

this should change your integer values into a string and show in dataframe

The trick is to use useradd instead of its interactive wrapper adduser. I usually create users with:

RUN useradd -ms /bin/bash newuser

which creates a home directory for the user and ensures that bash is the default shell.

You can then add:

USER newuser
WORKDIR /home/newuser

to your dockerfile. Every command afterwards as well as interactive sessions will be executed as user newuser:

docker run -t -i image
newuser@131b7ad86360:~$

You might have to give newuser the permissions to execute the programs you intend to run before invoking the user command.

Using non-privileged users inside containers is a good idea for security reasons. It also has a few drawbacks. Most importantly, people deriving images from your image will have to switch back to root before they can execute commands with superuser privileges.

You can get the results with a simple:

@app.route('your route', methods=['GET'])
def yourMethod(params):
    response = flask.jsonify({'some': 'data'})
    response.headers.add('Access-Control-Allow-Origin', '*')
    return response

The error is self explanatory. The path you are trying to access is not present.

string source_dir = "E:\\Debug\\VipBat\\{0}";

I'm sure that this is not the correct path. Debug folder directly in E: drive looks wrong to me. I guess there must be the project name folder directory present.

Second thing; what is {0} in your string. I am sure that it is an argument placeholder because folder name cannot contains {0} such name. So you need to use String.Format() to replace the actual value.

string source_dir = String.Format("E:\\Debug\\VipBat\\{0}",variableName);

But first check the path existence that you are trying to access.

for me this error came up when installing pygrib with conda and importing it.

conda install -c conda-forge numpy

solved the problem.

These are all good ideas in theory, until you go deep. The problem is you can't throttle an RAF without de-synchronizing it, defeating it's very purpose for existing. So you let it run at full-speed, and update your data in a separate loop, or even a separate thread!

Yes, I said it. You can do multi-threaded JavaScript in the browser!

There are two methods I know that work extremely well without jank, using far less juice and creating less heat. Accurate human-scale timing and machine efficiency are the net result.

Apologies if this is a little wordy, but here goes...

Method 1: Update data via setInterval, and graphics via RAF.

Use a separate setInterval for updating translation and rotation values, physics, collisions, etc. Keep those values in an object for each animated element. Assign the transform string to a variable in the object each setInterval 'frame'. Keep these objects in an array. Set your interval to your desired fps in ms: ms=(1000/fps). This keeps a steady clock that allows the same fps on any device, regardless of RAF speed. Do not assign the transforms to the elements here!

In a requestAnimationFrame loop, iterate through your array with an old-school for loop-- do not use the newer forms here, they are slow!

for(var i=0; i<sprite.length-1; i++){  rafUpdate(sprite[i]);  }

In your rafUpdate function, get the transform string from your js object in the array, and its elements id. You should already have your 'sprite' elements attached to a variable or easily accessible through other means so you don't lose time 'get'-ing them in the RAF. Keeping them in an object named after their html id's works pretty good. Set that part up before it even goes into your SI or RAF.

Use the RAF to update your transforms only, use only 3D transforms (even for 2d), and set css "will-change: transform;" on elements that will change. This keeps your transforms synced to the native refresh rate as much as possible, kicks in the GPU, and tells the browser where to concentrate most.

So you should have something like this pseudocode...

// refs to elements to be transformed, kept in an array
var element = [
   mario: document.getElementById('mario'),
   luigi: document.getElementById('luigi')
   //...etc.
]

var sprite = [  // read/write this with SI.  read-only from RAF
   mario: { id: mario  ....physics data, id, and updated transform string (from SI) here  },
   luigi: {  id: luigi  .....same  }
   //...and so forth
] // also kept in an array (for efficient iteration)

//update one sprite js object
//data manipulation, CPU tasks for each sprite object
//(physics, collisions, and transform-string updates here.)
//pass the object (by reference).
var SIupdate = function(object){
  // get pos/rot and update with movement
  object.pos.x += object.mov.pos.x;  // example, motion along x axis
  // and so on for y and z movement
  // and xyz rotational motion, scripted scaling etc

  // build transform string ie
  object.transform =
   'translate3d('+
     object.pos.x+','+
     object.pos.y+','+
     object.pos.z+
   ') '+

   // assign rotations, order depends on purpose and set-up. 
   'rotationZ('+object.rot.z+') '+
   'rotationY('+object.rot.y+') '+
   'rotationX('+object.rot.x+') '+

   'scale3d('.... if desired
  ;  //...etc.  include 
}


var fps = 30; //desired controlled frame-rate


// CPU TASKS - SI psuedo-frame data manipulation
setInterval(function(){
  // update each objects data
  for(var i=0; i<sprite.length-1; i++){  SIupdate(sprite[i]);  }
},1000/fps); //  note ms = 1000/fps


// GPU TASKS - RAF callback, real frame graphics updates only
var rAf = function(){
  // update each objects graphics
  for(var i=0; i<sprite.length-1; i++){  rAF.update(sprite[i])  }
  window.requestAnimationFrame(rAF); // loop
}

// assign new transform to sprite's element, only if it's transform has changed.
rAF.update = function(object){     
  if(object.old_transform !== object.transform){
    element[object.id].style.transform = transform;
    object.old_transform = object.transform;
  }
} 

window.requestAnimationFrame(rAF); // begin RAF

This keeps your updates to the data objects and transform strings synced to desired 'frame' rate in the SI, and the actual transform assignments in the RAF synced to GPU refresh rate. So the actual graphics updates are only in the RAF, but the changes to the data, and building the transform string are in the SI, thus no jankies but 'time' flows at desired frame-rate.

Flow:

[setup js sprite objects and html element object references]

[setup RAF and SI single-object update functions]

[start SI at percieved/ideal frame-rate]
  [iterate through js objects, update data transform string for each]
  [loop back to SI]

[start RAF loop]
  [iterate through js objects, read object's transform string and assign it to it's html element]
  [loop back to RAF]

Method 2. Put the SI in a web-worker. This one is FAAAST and smooth!

Same as method 1, but put the SI in web-worker. It'll run on a totally separate thread then, leaving the page to deal only with the RAF and UI. Pass the sprite array back and forth as a 'transferable object'. This is buko fast. It does not take time to clone or serialize, but it's not like passing by reference in that the reference from the other side is destroyed, so you will need to have both sides pass to the other side, and only update them when present, sort of like passing a note back and forth with your girlfriend in high-school.

Only one can read and write at a time. This is fine so long as they check if it's not undefined to avoid an error. The RAF is FAST and will kick it back immediately, then go through a bunch of GPU frames just checking if it's been sent back yet. The SI in the web-worker will have the sprite array most of the time, and will update positional, movement and physics data, as well as creating the new transform string, then pass it back to the RAF in the page.

This is the fastest way I know to animate elements via script. The two functions will be running as two separate programs, on two separate threads, taking advantage of multi-core CPU's in a way that a single js script does not. Multi-threaded javascript animation.

And it will do so smoothly without jank, but at the actual specified frame-rate, with very little divergence.

Result:

Either of these two methods will ensure your script will run at the same speed on any PC, phone, tablet, etc (within the capabilities of the device and the browser, of course).

     // shanegao's code in Swift 2.0
     func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject])
    {
            if ( application.applicationState == UIApplicationState.Inactive || application.applicationState == UIApplicationState.Background ){
                    print("opened from a push notification when the app was on background")
            }else{
                    print("opened from a push notification when the app was on foreground")
            }
    }

you can do that

var filteredFileList = fileList.Where(fl => filterList.Contains(fl.ToString()));

Be sure that Initial View Controller is set

I had the same issue that occurred when I was working with the VS GUI tool. What I did to fix it was I deleted the local repository and pulled it down from my git source - thank you git!! :)

This may not be the solution in all instances,. but by deleting all of the local files and recompiling, I was able to get it working again!

Doesn't the Directory.GetFiles(String, String) overload already do that? You would just do Directory.GetFiles(dir, "*.jpg", SearchOption.AllDirectories)

If you want to put them in a list, then just replace the "*.jpg" with a variable that iterates over a list and aggregate the results into an overall result set. Much clearer than individually specifying them. =)

Something like...

foreach(String fileExtension in extensionList){
    foreach(String file in Directory.GetFiles(dir, fileExtension, SearchOption.AllDirectories)){
        allFiles.Add(file);
    }
}

(If your directories are large, using EnumerateFiles instead of GetFiles can potentially be more efficient)

Simply try removing the ".xib" from the nib name in "initWithNibName:". According to the documentation, the ".xib" is assumed and shouldn't be used.

The easiest way to right pad a string with spaces (without them being trimmed) is to simply cast the string as CHAR(length). MSSQL will sometimes trim whitespace from VARCHAR (because it is a VARiable-length data type). Since CHAR is a fixed length datatype, SQL Server will never trim the trailing spaces, and will automatically pad strings that are shorter than its length with spaces. Try the following code snippet for example.

SELECT CAST('Test' AS CHAR(20))

This returns the value 'Test '.

Update 2019

In Bootstrap 4, flexbox can be used to get a full height layout that fills the remaining space.

First of all, the container (parent) needs to be full height:

Option 1_ Add a class for min-height: 100%;. Remember that min-height will only work if the parent has a defined height:

html, body {
  height: 100%;
}

.min-100 {
    min-height: 100%;
}

https://codeply.com/go/dTaVyMah1U

Option 2_ Use vh units:

.vh-100 {
    min-height: 100vh;
}

https://codeply.com/go/kMahVdZyGj

Also of Bootstrap 4.1, the vh-100 and min-vh-100 classes are included in Bootstrap so there is no need to for the extra CSS

Then, use flexbox direction column d-flex flex-column on the container, and flex-grow-1 on any child divs (ie: row) that you want to fill the remaining height.

Also see:
Bootstrap 4 Navbar and content fill height flexbox
Bootstrap - Fill fluid container between header and footer
How to make the row stretch remaining height

I'm pretty darn sure I just solved this with:

overflow-y: auto;

(Presumably just overflow: auto; would work too depending on your needs.)

SIGABRT is, as stated in other answers, a general uncaught exception. You should definitely learn a little bit more about Objective-C. The problem is probably in your UITableViewDelegate method didSelectRowAtIndexPath.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

I can't tell you much more until you show us something of the code where you handle the table data source and delegate methods.

In my case i had some problem with opacity transition so this one fix it:

#dropdown {
    transition:.6s opacity;
}
#dropdown.ns {
    opacity:0;
    transition:.6s all;
}
#dropdown.fade {
    opacity:1;
}

Mouse Enter

$('#dropdown').removeClass('ns').addClass('fade');

Mouse Leave

$('#dropdown').addClass('ns').removeClass('fade');

If you are still not getting device token, try putting following code so to register your device for push notification.

It will also work on ios8 or more.

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000

    if ([UIApplication respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound
                                                                                 categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    } else {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         UIRemoteNotificationTypeBadge |
         UIRemoteNotificationTypeAlert |
         UIRemoteNotificationTypeSound];

    }
#else
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeAlert |
     UIRemoteNotificationTypeSound];

#endif

If you're coming here wondering the opposite (as I was), this post may be for you.

I couldn't figure out why my notifications were clearing when I cleared the badge...I manually increment the badge and then want to clear it when the user enters the app. That's no reason to clear out the notification center, though; they may still want to see or act on those notifications.

Negative 1 does the trick, luckily:

[UIApplication sharedApplication].applicationIconBadgeNumber = -1;

Ideally you should try not to modify the internal data representation for the purpose of creating the table. Whats the problem with String.format()? It will return you new string with required width.

This happened to me. Solved by editing .plist file. Specify the Main nib file base name.(Should be MainWindow.xib). Hope this will help.

Maybe something like this (just add your style):

<input type="text" 
       size="35" 
       value="Job Title e.g. Assistant Manager" 
       style="background-color:white; 
              border: solid 1px #6E6E6E;
              height: 30px; 
              font-size:18px; 
              vertical-align:9px;color:#bbb" 
        onfocus="if(this.value == 'Job Title e.g. Assistant Manager') {
                    this.value = '';
                    this.style.color='#000';
                 }" />

<input type="text" 
       name="searchterm" size="35" 
       style="background-color:white; 
              border: solid 1px #6E6E6E;
              height: 30px; 
              font-size:18px; 
              vertical-align:9px" />

UPDATE: Since placeholder attribute is very well supported on all major browsers, there is no need to do anything manually. Its possible to achieve the same thing with this:

<input type="text" 
       size="35" 
       placeholder="Job Title e.g. Assistant Manager" />

If you give a Scanner object a String, it will read it in as data. That is, "a.txt" does not open up a file called "a.txt". It literally reads in the characters 'a', '.', 't' and so forth.

This is according to Core Java Volume I, section 3.7.3.

If I find a solution to reading the actual paths, I will return and update this answer. The solution this text offers is to use

Scanner in = new Scanner(Paths.get("myfile.txt"));

But I can't get this to work because Path isn't recognized as a variable by the compiler. Perhaps I'm missing an import statement.

You can use this to get all directories and sub-directories. Then simply loop through to process the files.

string[] folders = System.IO.Directory.GetDirectories(@"C:\My Sample Path\","*", System.IO.SearchOption.AllDirectories);

foreach(string f in folders)
{
   //call some function to get all files in folder
}

To fix this bug, I did:

1. In php.ini file, uncomment this line: extension=php_curl.dll
2. In php.ini file, uncomment this line: extension_dir = "ext"
3. I restarted NETBEANS, as I was using Built-in server

If for matching identical images - code for L2 distance

// Compare two images by getting the L2 error (square-root of sum of squared error).
double getSimilarity( const Mat A, const Mat B ) {
if ( A.rows > 0 && A.rows == B.rows && A.cols > 0 && A.cols == B.cols ) {
    // Calculate the L2 relative error between images.
    double errorL2 = norm( A, B, CV_L2 );
    // Convert to a reasonable scale, since L2 error is summed across all pixels of the image.
    double similarity = errorL2 / (double)( A.rows * A.cols );
    return similarity;
}
else {
    //Images have a different size
    return 100000000.0;  // Return a bad value
}

Fast. But not robust to changes in lighting/viewpoint etc. Source

In my application,above javascript function didnt work,because i had many procrosses inside one page.so following code worked for me hope it helps you guys.

  function redirection()
        {
           <?php $send=$_SERVER['HTTP_REFERER'];?> 
            var redirect_to="<?php echo $send;?>";             
            window.location = redirect_to;

        }

I prefer this:

str = "[12,23,987,43"
puts str[1..-1]
>> 12,23,987,43

you can set output format,eg to see only the command and the process id.

ps -eo pid,args

see the man page of ps for more output format. alternatively, you can use the -w or --width n options.

If all else fails, here's another workaround, (just to see your long cmds)

awk '{ split(FILENAME,f,"/") ; printf "%s: %s\n", f[3],$0 }' /proc/[0-9]*/cmdline

You need to escape quotes with double backslashes.

This fails (produced by PHP's json_encode):

<script>
  var jsonString = '[{"key":"my \"value\" "}]';
  var parsedJson = JSON.parse(jsonString);
</script>

This works:

<script>
  var jsonString = '[{"key":"my \\"value\\" "}]';
  var parsedJson = JSON.parse(jsonString);
</script>

The trick with relying upon IIS is that IIS bindings can be different from your public URLs (WCF I'm looking at you), especially with multi-homed production machines. I tend to vector toward using configuration to explicitly define the "base" url for external purposes as that tends to be a bit more successful than extracting it from the Request object.

The current way to do this is by using the "Add Service Reference" command. If you specify "TestUploaderWebService" as the service reference name, that will generate the type TestUploaderWebService.Service1. That class will have a method named GetFileListOnWebServer, which will return an array of strings (you can change that to be a list of strings if you like). You would use it like this:

string[] files = null;
TestUploaderWebService.Service1 proxy = null;
bool success = false;
try
{
    proxy = new TestUploaderWebService.Service1();
    files = proxy.GetFileListOnWebServer();
    proxy.Close();
    success = true;
}
finally
{
    if (!success)
    {
        proxy.Abort();
    }
}

P.S. Tell your instructor to look at "Microsoft: ASMX Web Services are a “Legacy Technology”", and ask why he's teaching out of date technology.

Via slice(indexStart, indexEnd) method - note, this does NOT CHANGE the existing string, it creates a copy and changes the copy.

console.clear();
let str = "12345.00";
let a = str.slice(0, str.length -1)
console.log(a, "<= a");
console.log(str, "<= str is NOT changed");

Via Regular Expression method - note, this does NOT CHANGE the existing string, it creates a copy and changes the copy.

console.clear();
let regExp = /.$/g
let b = str.replace(regExp,"")
console.log(b, "<= b");
console.log(str, "<= str is NOT changed");

Via array.splice() method -> this only works on arrays, and it CHANGES, the existing array (so careful with this one), you'll need to convert a string to an array first, then back.

console.clear();
let str = "12345.00";
let strToArray = str.split("")
console.log(strToArray, "<= strToArray");
let spliceMethod = strToArray.splice(str.length-1, 1)
str = strToArray.join("")
console.log(str, "<= str is changed now");

In my case I managed to fix the page break difficulties in webkit by setting my selected divs to page-break-inside:avoid, and also setting all elements to display:inline. So like this:

@media print{
* {
    display:inline;
}
script, style { 
    display:none; 
}
div {
    page-break-inside:avoid;
}

}

It seems like page-break-properties can only be applied to inline elements (in webkit). I tried to only apply display:inline to the particular elements I needed, but this didn't work. The only thing that worked was applying inline to all elements. I guess it's one of the large container div' that's messing things up.

Maybe someone could expand on this.

Project Euler is mentioned in the tags and many of the problems in it require checking numbers >> 2^64. Most of the optimizations mentioned above don't work easily when you are working with an 80 byte buffer.

I used java BigInteger and a slightly modified version of Newton's method, one that works better with integers. The problem was that exact squares n^2 converged to (n-1) instead of n because n^2-1 = (n-1)(n+1) and the final error was just one step below the final divisor and the algorithm terminated. It was easy to fix by adding one to the original argument before computing the error. (Add two for cube roots, etc.)

One nice attribute of this algorithm is that you can immediately tell if the number is a perfect square - the final error (not correction) in Newton's method will be zero. A simple modification also lets you quickly calculate floor(sqrt(x)) instead of the closest integer. This is handy with several Euler problems.

/// <summary>

/// <param name="srcDirs">The directories to seach</param>

public static string[] GetFilesUsingLINQ(string[] srcDirs,
     string[] searchPatterns,
     SearchOption searchOption = SearchOption.AllDirectories)
{
    var r = from dir in srcDirs
            from searchPattern in searchPatterns
            from f in Directory.GetFiles(dir, searchPattern, searchOption)
            select f;

    return r.ToArray();
}

I believe this is the easiest way to do it:

$lines = explode('???',wordwrap($string, $length, '???'));
$newstring = $lines[0] . ' • • •';

I'm using the special characters to split the text and cut it.

I usually use this little collection of extension methods:

public static class EnumerableExtension
{
    public static T PickRandom<T>(this IEnumerable<T> source)
    {
        return source.PickRandom(1).Single();
    }

    public static IEnumerable<T> PickRandom<T>(this IEnumerable<T> source, int count)
    {
        return source.Shuffle().Take(count);
    }

    public static IEnumerable<T> Shuffle<T>(this IEnumerable<T> source)
    {
        return source.OrderBy(x => Guid.NewGuid());
    }
}

For a strongly typed list, this would allow you to write:

var strings = new List<string>();
var randomString = strings.PickRandom();

If all you have is an ArrayList, you can cast it:

var strings = myArrayList.Cast<string>();

http://example.com/ may resolve to a different VirtualHost than https://example.com/ (which, as the Host header is not sent, responds to the default for that IP), so the two are treated as separate domains and thus subject to crossdomain JS restrictions.

JSON callbacks may let you avoid this.

tl;dr

Instant stop = 
    myUtilDateStart.toInstant()
                   .plus( Duration.ofMinutes( x ) ) 
;

java.time

Other Answers are correct, especially the Answer by Borgwardt. But those Answers use outmoded legacy classes.

The original date-time classes bundled with Java have been supplanted with java.time classes. Perform your business logic in java.time types. Convert to the old types only where needed to work with old code not yet updated to handle java.time types.

If your Calendar is actually a GregorianCalendar you can convert to a ZonedDateTime. Find new methods added to the old classes to facilitate conversion to/from java.time types.

if( myUtilCalendar instanceof GregorianCalendar ) {
    GregorianCalendar gregCal = (GregorianCalendar) myUtilCalendar; // Downcasting from the interface to the concrete class.
    ZonedDateTime zdt = gregCal.toZonedDateTime();  // Create `ZonedDateTime` with same time zone info found in the `GregorianCalendar`
end if 

If your Calendar is not a Gregorian, call toInstant to get an Instant object. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = myCal.toInstant();

Similarly, if starting with a java.util.Date object, convert to an Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = myUtilDate.toInstant();

Apply a time zone to get a ZonedDateTime.

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

To get a java.util.Date object, go through the Instant.

java.util.Date utilDate = java.util.Date.from( zdt.toInstant() );

For more discussion of converting between the legacy date-time types and java.time, and a nifty diagram, see my Answer to another Question.

Duration

Represent the span of time as a Duration object. Your input for the duration is a number of minutes as mentioned in the Question.

Duration d = Duration.ofMinutes( yourMinutesGoHere );

You can add that to the start to determine the stop.

Instant stop = startInstant.plus( d ); 

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

In SQL Server 2012 you have IIF, e.g you can use it like

SELECT IIF(field IS NULL, 1, 0) AS IsNull

The same way you can check if field is empty.

in continuation to @ Cuong Le's answer , my approach to prevent replay attack would be

// Encrypt the Unix Time at Client side using the shared private key(or user's password)

// Send it as part of request header to server(WEB API)

// Decrypt the Unix Time at Server(WEB API) using the shared private key(or user's password)

// Check the time difference between the Client's Unix Time and Server's Unix Time, should not be greater than x sec

// if User ID/Hash Password are correct and the decrypted UnixTime is within x sec of server time then it is a valid request

As per official documentation link shared by Andre Kirpitch, Oracle 10g gives a maximum size of 4000 bytes or characters for varchar2. If you are using a higher version of oracle (for example Oracle 12c), you can get a maximum size upto 32767 bytes or characters for varchar2. To utilize the extended datatype feature of oracle 12, you need to start oracle in upgrade mode. Follow the below steps in command prompt:

1) Login as sysdba (sqlplus / as sysdba)

2) SHUTDOWN IMMEDIATE;

3) STARTUP UPGRADE;

4) ALTER SYSTEM SET max_string_size=extended;

5) Oracle\product\12.1.0.2\rdbms\admin\utl32k.sql

6) SHUTDOWN IMMEDIATE;

7) STARTUP;

if you want to add the data in the increment order inside your associative array you can do this:

$newdata =  array (
      'wpseo_title' => 'test',
      'wpseo_desc' => 'test',
      'wpseo_metakey' => 'test'
    );

// for recipe

$md_array["recipe_type"][] = $newdata;

//for cuisine

 $md_array["cuisine"][] = $newdata;

this will get added to the recipe or cuisine depending on what was the last index.

Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this

array_push($md_array["cuisine"],$newdata);

The following is adapted from here MySQL What is DDL, DML and DCL?:

DDL

DDL is short name of Data Definition Language, which deals with database schemas and descriptions, of how the data should reside in the database.

• CREATE – to create database and its objects like (table, index, views, store procedure, function and triggers).
• ALTER – alters the structure of the existing database.
• DROP – delete objects from the database.
• TRUNCATE – remove all records from a table; also, all spaces allocated for the records are removed.
• COMMENT – add comments to the data dictionary.
• RENAME – rename an object.

DML

DML is short name of Data Manipulation Language which deals with data manipulation, and includes most common SQL statements such SELECT, INSERT, UPDATE, DELETE etc, and it is used to store, modify, retrieve, delete and update data in database.

• SELECT – retrieve data from one or more tables.
• INSERT – insert data into a table.
• UPDATE – updates existing data within a table.
• DELETE – delete all records from a table.
• MERGE – UPSERT operation (insert or update)
• CALL – call a PL/SQL or Java subprogram.
• EXPLAIN PLAN – interpretation of the data access path.
• LOCK TABLE – concurrency control.

DCL

DCL is short name of Data Control Language which includes commands such as GRANT, and mostly concerned with rights, permissions and other controls of the database system.

• GRANT – allow users access privileges to database.
• REVOKE – withdraw users access privileges given by using the GRANT command.

TCL

TCL is short name of Transaction Control Language which deals with transaction within a database.

• COMMIT – commits a transaction.
• ROLLBACK – rollback a transaction in case of any error occurs.
• SAVEPOINT – a point inside a transaction that allows rollback state to what it was at the time of the savepoint.
• SET TRANSACTION – specify characteristics for the transaction.

There are lots of good answers here, but there is also something i'd like to add:

• If you are running on AWS ElasticSearch service, you can´t drop/delete indexes. Instead of delete indexes, you must reindex them.

Using IIS manager, I found that .aspx files were mapped (under "Handler Mappings") to ISAPI 2.0 - even though ASP.NET 4.5 had been previously installed. Editing them to point (also) to an executable for ISAPI 4.0 64bit fixed the issue.

The executable was found in %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll

Go to https://university.xamarin.com/resources/working-with-android-emulators . Scroll down to the "Installing Google Play Services" section. Step by step walk through there.

Directly plagarized from xamarin here so I don't get dinged for linking and not including solution. Posting this as I found the hit in stack before I found the solution that worked across the board on the xamarin page.

1. Start the Xamarin Android Player and run one of the supplied images, the following assumes you have started the KitKat Nexus 4 image. Download the proper Google Play Services .zip file from www.teamandroid.com/gapps/ . Make sure to download the image appropriate for your version of Android.
2. Drag the .zip file onto the running emulator and drop it to install the component, here we show it on Mac OS X, but the same mechanism is used in Windows. You will get a prompt to install the package onto the emulator which indicates the image will be restarted
3. Once it restarts, you will get a notification that installation is completed, and the image will now have Google Maps, Google+ and support for the Google Play store. Note that some things do not work correctly and you may get a few errors from some of the services, but you can safely dismiss these and continue the instructions.
4. Next, you will need to associate a Google account so that you can update the services using the Google Play store. It should prompt you for this, but if it does not, you can go into the Google Settings and add a new account. Once you've added the account, you can then update the Google apps by opening the Google Play store application and going into settings from the side bar menu.
5. Select Settings and then scroll down to the Build Version number information and double-tap on it until it tells you it is either up-to-date, or that it will download and install a new version.
6. Power off the device (press and hold the power button in the toolbar on the right) and restart it. Once it restarts, it should indicate that it needs to update the Google Play services, tapping the notification will open the Google Play Store and install the latest version

Now you can run applications that depend on Google Maps in the Xamarin Android Player.

SELECT * FROM my_table;

where my_table is the name of your table.

EDIT:

psql -c "SELECT * FROM my_table"

or just psql and then type your queries.

You may change the pg_hba.conf and then reload the postgresql. something in the pg_hba.conf may be like below:

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

then you change your user to postgresql, you may login successfully.

su postgresql

If constraint on column STATUS was created without a name during creating a table, Oracle will assign a random name for it. Unfortunately, we cannot modify the constraint directly.

Steps involved of dropping unnamed constraint linked to column STATUS

1. Duplicate STATUS field into a new field STATUS2
2. Define CHECK constraints on STATUS2
3. Migrate data from STATUS into STATUS2
4. Drop STATUS column

5. Rename STATUS2 to STATUS

   ALTER TABLE MY_TABLE ADD STATUS2 NVARCHAR2(10) DEFAULT 'OPEN'; ALTER TABLE MY_TABLE ADD CONSTRAINT MY_TABLE_CHECK_STATUS CHECK (STATUS2 IN ('OPEN', 'CLOSED')); UPDATE MY_TABLE SET STATUS2 = STATUS; ALTER TABLE MY_TABLE DROP COLUMN STATUS; ALTER TABLE MY_TABLE RENAME COLUMN STATUS2 TO STATUS;

Try double-clicking on the bottom right hand corner of the cell (ie on the box that you would otherwise drag).

I'm adding this answer because I didn’t see it here in full. I was able to do this using elementFromPoint. So basically:

• attach a click to the div you want to be clicked through
• hide it
• determine what element the pointer is on
• fire the click on the element there.

var range-selector= $("")
    .css("position", "absolute").addClass("range-selector")
    .appendTo("")
    .click(function(e) {
        _range-selector.hide();

        $(document.elementFromPoint(e.clientX,e.clientY)).trigger("click");
    });

In my case the overlaying div is absolutely positioned—I am not sure if this makes a difference. This works on IE8/9, Safari Chrome and Firefox at least.

Your method must read byte by byte and fully understand and appreciate the byte wise construction of characters. The simplest method is to use an editor which will read anything but only output UTF-8 characters. Textpad is one choice.

I use something like this (you should add code to deal with the various fails):

    var response = RunTaskWithTimeout<ReturnType>(
        (Func<ReturnType>)delegate { return SomeMethod(someInput); }, 30);


    /// <summary>
    /// Generic method to run a task on a background thread with a specific timeout, if the task fails,
    /// notifies a user
    /// </summary>
    /// <typeparam name="T">Return type of function</typeparam>
    /// <param name="TaskAction">Function delegate for task to perform</param>
    /// <param name="TimeoutSeconds">Time to allow before task times out</param>
    /// <returns></returns>
    private T RunTaskWithTimeout<T>(Func<T> TaskAction, int TimeoutSeconds)
    {
        Task<T> backgroundTask;

        try
        {
            backgroundTask = Task.Factory.StartNew(TaskAction);
            backgroundTask.Wait(new TimeSpan(0, 0, TimeoutSeconds));
        }
        catch (AggregateException ex)
        {
            // task failed
            var failMessage = ex.Flatten().InnerException.Message);
            return default(T);
        }
        catch (Exception ex)
        {
            // task failed
            var failMessage = ex.Message;
            return default(T);
        }

        if (!backgroundTask.IsCompleted)
        {
            // task timed out
            return default(T);
        }

        // task succeeded
        return backgroundTask.Result;
    }

Verifying ele is visible.

public static boolean isElementVisible(final By by)
    throws InterruptedException {
        boolean value = false;

        if (driver.findElements(by).size() > 0) {
            value = true;

For me it worked

if needle in haystack: is the normal use, as @Michael says -- it relies on the in operator, more readable and faster than a method call.

If you truly need a method instead of an operator (e.g. to do some weird key= for a very peculiar sort...?), that would be 'haystack'.__contains__. But since your example is for use in an if, I guess you don't really mean what you say;-). It's not good form (nor readable, nor efficient) to use special methods directly -- they're meant to be used, instead, through the operators and builtins that delegate to them.

for my specific problem I had to replace

if let count = 1
    {
        // do something ...
    }

With

let count = 1
if(count > 0)
    {
        // do something ...
    }

This is a quick example

plot(rnorm(30), xlab = expression(paste("4"^"th")))

I wrote a full replacement for sys.stderr and just duplicated the code renaming stderr to stdout to make it also available to replace sys.stdout.

To use this you can just call StdErrReplament::lock(logger) and StdOutReplament::lock(logger) passing the logger you want to use to send the output text. For example:

import os
import sys
import logging

current_folder = os.path.dirname( os.path.realpath( __file__ ) )
log_file_path = os.path.join( current_folder, "my_log_file.txt" )

file_handler = logging.FileHandler( log_file_path, 'a' )
file_handler.formatter = logging.Formatter( "%(asctime)s %(name)s %(levelname)s - %(message)s", "%Y-%m-%d %H:%M:%S" )

log = logging.getLogger( __name__ )
log.setLevel( "DEBUG" )
log.addHandler( file_handler )

log.file_handler = file_handler
log.clean_formatter = logging.Formatter( "", "" )

StdOutReplament.lock( log )
StdErrReplament.lock( log )

log.debug( "I am doing usual logging debug..." )
sys.stderr.write( "Tests 1...\n" )
sys.stdout.write( "Tests 2...\n" )

Running this code, you will see on the screen:

And on the file contents:

If you would like to also see the contents of the log.debug calls on the screen, you will need to add a stream handler to your logger. On this case it would be like this:

import os
import sys
import logging

class ContextFilter(logging.Filter):
    """ This filter avoids duplicated information to be displayed to the StreamHandler log. """
    def filter(self, record):
        return not "_duplicated_from_file" in record.__dict__

current_folder = os.path.dirname( os.path.realpath( __file__ ) )
log_file_path = os.path.join( current_folder, "my_log_file.txt" )

stream_handler = logging.StreamHandler()
file_handler = logging.FileHandler( log_file_path, 'a' )

formatter = logging.Formatter( "%(asctime)s %(name)s %(levelname)s - %(message)s", "%Y-%m-%d %H:%M:%S" )
file_handler.formatter = formatter
stream_handler.formatter = formatter
stream_handler.addFilter( ContextFilter() )

log = logging.getLogger( __name__ )
log.setLevel( "DEBUG" )
log.addHandler( file_handler )
log.addHandler( stream_handler )

log.file_handler = file_handler
log.stream_handler = stream_handler
log.clean_formatter = logging.Formatter( "", "" )

StdOutReplament.lock( log )
StdErrReplament.lock( log )

log.debug( "I am doing usual logging debug..." )
sys.stderr.write( "Tests 1...\n" )
sys.stdout.write( "Tests 2...\n" )

Which would output like this when running:

While it would still saving this to the file my_log_file.txt:

When disabling this with StdErrReplament:unlock(), it will only restore the standard behavior of the stderr stream, as the attached logger cannot be never detached because someone else can have a reference to its older version. This is why it is a global singleton which can never dies. Therefore, in case of reloading this module with imp or something else, it will never recapture the current sys.stderr as it was already injected on it and have it saved internally.

I did it with these values within a LinearLayout:

The problem is that [...] in python has two distinct meanings

1. expr [ index ] means accessing an element of a list
2. [ expr1, expr2, expr3 ] means building a list of three elements from three expressions

In your code you forgot the comma between the expressions for the items in the outer list:

[ [a, b, c] [d, e, f] [g, h, i] ]

therefore Python interpreted the start of second element as an index to be applied to the first and this is what the error message is saying.

The correct syntax for what you're looking for is

[ [a, b, c], [d, e, f], [g, h, i] ]

SUPER-SHIFT-p > File: Revert File is the only way

(where SUPER is Command on Mac and Ctrl on PC)

Despite the danger of stating the obvious: With a unit test you want to test the correct behaviour of the object - and this is defined in terms of its public interface. You are not interested in how the object accomplishes this task - this is an implementation detail and not visible to the outside. This is one of the things why OO was invented: That implementation details are hidden. So there is no point in testing private members. You said you need 100% coverage. If there is a piece of code that cannot be tested by using the public interface of the object, then this piece of code is actually never called and hence not testable. Remove it.

Let me state it clearly that you can use the string overload to include nested levels regardless of the multiplicities of the corresponding relationships, if you don't mind using string literals:

query.Include("Collection.Property")

You can use either of the two statements below:

numpy.mean(df['col_name'])
# or
df['col_name'].mean()

@PrePersist
void preInsert() {
    if (this.dateOfConsent == null)
        this.dateOfConsent = LocalDateTime.now();
    if(this.consentExpiry==null)
        this.consentExpiry = this.dateOfConsent.plusMonths(3);
}

In my case due to the field being LocalDateTime i used this, it is recommended due to vendor independence

You can use the is_cart() conditional tag:

if (! is_cart() ) {
  // Do something.
}

Left Ctrl + F11 works on Windows.

After trying several methods, to summarize it, this is how I did it. Following are two ways of avoiding/removing \xa0 characters from parsed HTML string.

Assume we have our raw html as following:

raw_html = '<p>Dear Parent, </p><p><span style="font-size: 1rem;">This is a test message, </span><span style="font-size: 1rem;">kindly ignore it. </span></p><p><span style="font-size: 1rem;">Thanks</span></p>'

So lets try to clean this HTML string:

from bs4 import BeautifulSoup
raw_html = '<p>Dear Parent, </p><p><span style="font-size: 1rem;">This is a test message, </span><span style="font-size: 1rem;">kindly ignore it. </span></p><p><span style="font-size: 1rem;">Thanks</span></p>'
text_string = BeautifulSoup(raw_html, "lxml").text
print text_string
#u'Dear Parent,\xa0This is a test message,\xa0kindly ignore it.\xa0Thanks'

The above code produces these characters \xa0 in the string. To remove them properly, we can use two ways.

Method # 1 (Recommended): The first one is BeautifulSoup's get_text method with strip argument as True So our code becomes:

clean_text = BeautifulSoup(raw_html, "lxml").get_text(strip=True)
print clean_text
# Dear Parent,This is a test message,kindly ignore it.Thanks

Method # 2: The other option is to use python's library unicodedata

import unicodedata
text_string = BeautifulSoup(raw_html, "lxml").text
clean_text = unicodedata.normalize("NFKD",text_string)
print clean_text
# u'Dear Parent,This is a test message,kindly ignore it.Thanks'

I have also detailed these methods on this blog which you may want to refer.

First of all: Don't put secrets in clear text unless you know why it is a safe thing to do (i.e. you have assessed what damage can be done by an attacker knowing the secret).

If you are ok with putting secrets in your script, you could ship an ssh key with it and execute in an ssh-agent shell:

#!/usr/bin/env ssh-agent /usr/bin/env bash
KEYFILE=`mktemp`
cat << EOF > ${KEYFILE}
-----BEGIN RSA PRIVATE KEY-----
[.......]
EOF
ssh-add ${KEYFILE}

# do your ssh things here...

# Remove the key file.
rm -f ${KEYFILE}

A benefit of using ssh keys is that you can easily use forced commands to limit what the keyholder can do on the server.

A more secure approach would be to let the script run ssh-keygen -f ~/.ssh/my-script-key to create a private key specific for this purpose, but then you would also need a routine for adding the public key to the server.

I thought I would add to this question as it is the top google search result.

As has been noted in the comments, in EF Core there is no support for using annotations (Key attribute) and it must be done with fluent.

As I was working on a large migration from EF6 to EF Core this was unsavoury and so I tried to hack it by using Reflection to look for the Key attribute and then apply it during OnModelCreating

// get all composite keys (entity decorated by more than 1 [Key] attribute
foreach (var entity in modelBuilder.Model.GetEntityTypes()
    .Where(t => 
        t.ClrType.GetProperties()
            .Count(p => p.CustomAttributes.Any(a => a.AttributeType == typeof(KeyAttribute))) > 1))
{
    // get the keys in the appropriate order
    var orderedKeys = entity.ClrType
        .GetProperties()
        .Where(p => p.CustomAttributes.Any(a => a.AttributeType == typeof(KeyAttribute)))
        .OrderBy(p => 
            p.CustomAttributes.Single(x => x.AttributeType == typeof(ColumnAttribute))?
                .NamedArguments?.Single(y => y.MemberName == nameof(ColumnAttribute.Order))
                .TypedValue.Value ?? 0)
        .Select(x => x.Name)
        .ToArray();

    // apply the keys to the model builder
    modelBuilder.Entity(entity.ClrType).HasKey(orderedKeys);
}

I haven't fully tested this in all situations, but it works in my basic tests. Hope this helps someone

Here's how to get the filepath of the file in Excel 2010.

1) Right click on the Ribbon.
2) Click on "Customize the Ribbon"
3) On the right hand side, click "New Group." This will add a new tab to the Ribbon. If you want to, click on the "Rename" button the right side and name your tab. For example, I named the tab "Doc Path." This step is optional
4) Under "Choose Commands From" on the left hand side, choose "Commands Not in the Ribbon."
5) Select "Document Location" and "Add" it to your newly created group.
6) The filepath should now appear under the newly created tab on the ribbon.

Just an additional note about reflection: I have observed in some special cases, when several classes with the same name exist in different packages, that reflection as used in the top answer may fail to pick the correct class from the object. So if you know what is the package.class of the object, then it's better to access its private field values as follows:

org.deeplearning4j.nn.layers.BaseOutputLayer ll = (org.deeplearning4j.nn.layers.BaseOutputLayer) model.getLayer(0);
Field f = Class.forName("org.deeplearning4j.nn.layers.BaseOutputLayer").getDeclaredField("solver");
f.setAccessible(true);
Solver s = (Solver) f.get(ll);

(This is the example class that was not working for me)

Use the constructor: new List<object>(myArray)

I also wanted to know why 2 GAC and found the following explanation by Mark Miller in the comments section of .NET 4.0 has 2 Global Assembly Cache (GAC):

Mark Miller said... June 28, 2010 12:13 PM

Thanks for the post. "Interference issues" was intentionally vague. At the time of writing, the issues were still being investigated, but it was clear there were several broken scenarios.

For instance, some applications use Assemby.LoadWithPartialName to load the highest version of an assembly. If the highest version was compiled with v4, then a v2 (3.0 or 3.5) app could not load it, and the app would crash, even if there were a version that would have worked. Originally, we partitioned the GAC under it's original location, but that caused some problems with windows upgrade scenarios. Both of these involved code that had already shipped, so we moved our (version-partitioned GAC to another place.

This shouldn't have any impact to most applications, and doesn't add any maintenance burden. Both locations should only be accessed or modified using the native GAC APIs, which deal with the partitioning as expected. The places where this does surface are through APIs that expose the paths of the GAC such as GetCachePath, or examining the path of mscorlib loaded into managed code.

It's worth noting that we modified GAC locations when we released v2 as well when we introduced architecture as part of the assembly identity. Those added GAC_MSIL, GAC_32, and GAC_64, although all still under %windir%\assembly. Unfortunately, that wasn't an option for this release.

Hope it helps future readers.

From the YouTube help:

You will automatically be opted into showing ads on embedded videos if you've associated your YouTube and AdSense accounts and have enabled your videos for embedding.

If you don't want to show overlay ads on your embedded videos, you can opt your videos out of showing overlay ads, though this will also disable overlay ads on your videos on YouTube.com. You may also disable your videos for embedding.

https://support.google.com/youtube/answer/132596?hl=en

Another technical solution could be to use a custom video player, and streamline the youtube video with that one. Have not tried but guess that the ads cannot be displayed in a custom player. However, could be forbidden.

If you are using Spring Have a look at PathMatchingResourcePatternResolver

You should use the * operator, like foo(*values) Read the Python doc unpackaging argument lists.

Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/

def foo(x,y,z):
   return "%d, %d, %d" % (x,y,z)

values = [1,2,3]

# the solution.
foo(*values)

$(this).unbind('mouseenter').unbind('mouseleave')

or more succinctly (thanks @Chad Grant):

$(this).unbind('mouseenter mouseleave')

Since you're using Spring, stick with Spring, don't hack it yourself like the other post posits.

The Spring manual says:

You shouldn't interact directly with the HttpSession for security purposes. There is simply no justification for doing so - always use the SecurityContextHolder instead.

The suggested best practice for accessing the session is:

Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

if (principal instanceof UserDetails) {
  String username = ((UserDetails)principal).getUsername();
} else {
  String username = principal.toString();
}

The key here is that Spring and Spring Security do all sorts of great stuff for you like Session Fixation Prevention. These things assume that you're using the Spring framework as it was designed to be used. So, in your servlet, make it context aware and access the session like the above example.

If you just need to stash some data in the session scope, try creating some session scoped bean like this example and let autowire do its magic. :)

The Clear method is defined as

    public void Clear() { 
        Text = null;
    } 

The Text property's setter starts with

        set { 
            if (value == null) { 
                value = "";
            } 

I assume this answers your question.

yes stale element error is thrown when (taking your scenario) you have defined locator strategy to click on 'Add Item' first and then when you close the pop up the page gets refreshed hence the reference defined for 'Add Item' is lost in the memory so to overcome this you have to redefine the locator strategy for 'Add Item' again

understand it with a dummy code

// clicking on view details 
driver.findElement(By.id("")).click();
// closing the pop up 
driver.findElement(By.id("")).click();


// and when you try to click on Add Item
driver.findElement(By.id("")).click();
// you get stale element exception as reference to add item is lost 
// so to overcome this you have to re identify the locator strategy for add item 
// Please note : this is one of the way to overcome stale element exception 

// Step 1 please add a universal wait in your script like below 
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS); // just after you have initiated browser

I ran into the same issue a while ago and did solve it by using reflection with some help from Jackson.

First populate a map with all the fields on an Object. Then add those map entries as parameters to the MockHttpServletRequestBuilder.

In this way you can use any Object and you are passing it as request parameters. I'm sure there are other solutions out there but this one worked for us:

    @Test
    public void testFormEdit() throws Exception {
        getMockMvc()
                .perform(
                        addFormParameters(post(servletPath + tableRootUrl + "/" + POST_FORM_EDIT_URL).servletPath(servletPath)
                                .param("entityID", entityId), validEntity)).andDo(print()).andExpect(status().isOk())
                .andExpect(content().contentType(MediaType.APPLICATION_JSON)).andExpect(content().string(equalTo(entityId)));
    }

    private MockHttpServletRequestBuilder addFormParameters(MockHttpServletRequestBuilder builder, Object object)
            throws IllegalAccessException, InvocationTargetException, NoSuchMethodException {

        SimpleDateFormat dateFormat = new SimpleDateFormat(applicationSettings.getApplicationDateFormat());

        Map<String, ?> propertyValues = getPropertyValues(object, dateFormat);

        for (Entry<String, ?> entry : propertyValues.entrySet()) {
            builder.param(entry.getKey(),
                    Util.prepareDisplayValue(entry.getValue(), applicationSettings.getApplicationDateFormat()));
        }

        return builder;
    }

    private Map<String, ?> getPropertyValues(Object object, DateFormat dateFormat) {
        ObjectMapper mapper = new ObjectMapper();
        mapper.setDateFormat(dateFormat);
        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        mapper.registerModule(new JodaModule());

        TypeReference<HashMap<String, ?>> typeRef = new TypeReference<HashMap<String, ?>>() {};

        Map<String, ?> returnValues = mapper.convertValue(object, typeRef);

        return returnValues;

    }

The practical solution is to use CSS to actually hide the input.

To take this to its natural conclusion, you can write two html inputs for each actual input (one enabled, and one disabled) and then use javascript to control the CSS to show and hide them.

Based in @TMS answer, I like it because there's no need for subqueries but I think ommiting the 'OR' part will be sufficient and much simpler to understand and read.

SELECT t1.*
FROM lms_attendance AS t1
LEFT JOIN lms_attendance AS t2
  ON t1.user = t2.user 
        AND t1.time < t2.time
WHERE t2.user IS NULL

if you are not interested in rows with null times you can filter them in the WHERE clause:

SELECT t1.*
FROM lms_attendance AS t1
LEFT JOIN lms_attendance AS t2
  ON t1.user = t2.user 
        AND t1.time < t2.time
WHERE t2.user IS NULL and t1.time IS NOT NULL

Uninstall node-sass

npm uninstall node-sass

use sass by:

npm install -g sass
npm install --save-dev sass

Follow the below example --

songs = [
{"title": "happy birthday", "playcount": 4},
{"title": "AC/DC", "playcount": 2},
{"title": "Billie Jean", "playcount": 6},
{"title": "Human Touch", "playcount": 3}
]

print("====================")
print(f'Songs --> {songs} \n')
title = list(map(lambda x : x['title'], songs))
print(f'Print Title --> {title}')

playcount = list(map(lambda x : x['playcount'], songs))
print(f'Print Playcount --> {playcount}')
print (f'Print Sorted playcount --> {sorted(playcount)}')

# Aliter -
print(sorted(list(map(lambda x: x['playcount'],songs))))

int[] n=new int[5];

for (int i = 0; i < 5; i++)
{
    n[i] = i + 100;
}

foreach (int j in n)
{
    int i = j - 100;

    Console.WriteLine("Element [{0}]={1}", i, j);
    i++;
}

If you are only saving a single object (your data frame), you could also use saveRDS.
To save:

saveRDS(foo, file="data.Rda")

Then read it with:

bar <- readRDS(file="data.Rda")

The difference between saveRDS and save is that in the former only one object can be saved and the name of the object is not forced to be the same after you load it.

Try this batch :

@echo off
Title List of connected external devices by Hackoo
Mode con cols=100 lines=20 & Color 9E
wmic LOGICALDISK where driveType=2 get deviceID > wmic.txt
for /f "skip=1" %%b IN ('type wmic.txt') DO (echo %%b & pause & Dir %%b)
Del wmic.txt
pause

I wanted to keep my changes so, I just fix this doing...

git add .
git commit -m "Title" -m "Description"
(so i have a commit now example: 123abc)
git checkout YOURCURRENTBRANCH
git merge 123abc
git push TOYOURCURRENTBRANCH

that work for me

First set a custom attribute into your option for example nameid (you can set non-standardized attribute of an HTML element, it's allowed):

'<option nameid= "' + n.id + "' value="' + i + '">' + n.names + '</option>'

then you can easily get attribute value using jquery .attr() :

$('option:selected').attr("nameid")

For Example:

<select id="jobSel" class="longcombo" onchange="GetNameId">
    <option nameid="32" value="1">test1</option>
    <option nameid="67" value="1">test2</option>
    <option nameid="45" value="1">test3</option>    
    </select>    

Jquery:

function GetNameId(){
   alert($('#jobSel option:selected').attr("nameid"));
}

jsonIssues = [...jsonIssues,{ID:'3',Name:'name 3',Notes:'NOTES 3'}]

I assume that your style-sheet "style.css" is already located in the assets-folder

1. load the web-page with jsoup:

   doc = Jsoup.connect("http://....").get();
   

2. remove links to external style-sheets:

   // remove links to external style-sheets
   doc.head().getElementsByTag("link").remove();
   

3. set link to local style-sheet:

   // set link to local stylesheet
   // <link rel="stylesheet" type="text/css" href="style.css" />
   doc.head().appendElement("link").attr("rel", "stylesheet").attr("type", "text/css").attr("href", "style.css");
   

4. make string from jsoup-doc/web-page:

   String htmldata = doc.outerHtml();
   

5. display web-page in webview:

   WebView webview = new WebView(this);
   setContentView(webview);
   webview.loadDataWithBaseURL("file:///android_asset/.", htmlData, "text/html", "UTF-8", null);
   

If your are on windows you can do it this way :

1. In your project root directory, Create file run.bat
2. Add your command with your choice of configurations in this file. For Example

ng serve --host 192.168.1.2 --open

3. Now you can click and open this file whenever you want to serve.

This not standard way but comfortable to use (which I feel).

Try this :

sp_help 'TableName'

This code calculate difference between two dates in yyyy MM dd format.

declare @StartDate datetime 
declare @EndDate datetime

declare @years int
declare @months int 
declare @days int

--NOTE: date of birth must be smaller than As on date, 
--else it could produce wrong results
set @StartDate = '2013-12-30' --birthdate
set @EndDate  = Getdate()            --current datetime

--calculate years
select @years = datediff(year,@StartDate,@EndDate)

--calculate months if it's value is negative then it 
--indicates after __ months; __ years will be complete
--To resolve this, we have taken a flag @MonthOverflow...
declare @monthOverflow int
select @monthOverflow = case when datediff(month,@StartDate,@EndDate) - 
  ( datediff(year,@StartDate,@EndDate) * 12) <0 then -1 else 1 end
--decrease year by 1 if months are Overflowed
select @Years = case when @monthOverflow < 0 then @years-1 else @years end
select @months =  datediff(month,@StartDate,@EndDate) - (@years * 12) 

--as we do for month overflow criteria for days and hours 
--& minutes logic will followed same way
declare @LastdayOfMonth int
select @LastdayOfMonth =  datepart(d,DATEADD
    (s,-1,DATEADD(mm, DATEDIFF(m,0,@EndDate)+1,0)))

select @days = case when @monthOverflow<0 and 
    DAY(@StartDate)> DAY(@EndDate) 
then @LastdayOfMonth + 
  (datepart(d,@EndDate) - datepart(d,@StartDate) ) - 1  
      else datepart(d,@EndDate) - datepart(d,@StartDate) end 


select
 @Months=case when @days < 0 or DAY(@StartDate)> DAY(@EndDate) then @Months-1 else @Months end

Declare @lastdayAsOnDate int;
set @lastdayAsOnDate = datepart(d,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@EndDate),0)));
Declare @lastdayBirthdate int;
set @lastdayBirthdate =  datepart(d,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@StartDate)+1,0)));

if (@Days < 0) 
(
    select @Days = case when( @lastdayBirthdate > @lastdayAsOnDate) then
        @lastdayBirthdate + @Days
    else
        @lastdayAsOnDate + @Days
    end
)
print  convert(varchar,@years)   + ' year(s),   '  +
       convert(varchar,@months)  + ' month(s),   ' +
       convert(varchar,@days)    + ' day(s)   '   

It happen if there are two more ContextLoaderListener exist in your project.

For ex: in my case 2 ContextLoaderListener was exist using

1. java configuration
2. web.xml

So, remove any one ContextLoaderListener from your project and run your application.

<init-param> will be used if you want to initialize some parameter for a particular servlet. When request come to servlet first its init method will be called then doGet/doPost whereas if you want to initialize some variable for whole application you will need to use <context-param> . Every servlet will have access to the context variable.

Here is another method to iterate through an object.

   var p = {_x000D_
"p1": "value1",_x000D_
"p2": "value2",_x000D_
"p3": "value3"_x000D_
};_x000D_
_x000D_
_x000D_
Object.keys(p).forEach(key => { console.log(key, p[key]) })

Google has introduced new AndroidX dependencies. You need to migrate to AndroidX, it's simple.

I replaced all dependencies to AndroidX dependencies

Old design dependency

implementation 'com.android.support:design:28.0.0'

New AndroidX design dependency

implementation 'com.google.android.material:material:1.0.0-rc01'

you can find AndroidX dependencies here https://developer.android.com/jetpack/androidx/migrate

Automatic AndroidX migration option (supported on android studio 3.3+)

Migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

I believe python arrays just admit values. So convert it to list:

kOUT = np.zeros(N+1)
kOUT = kOUT.tolist()

I like to use flutter_mobx for this and work on the state.

Next I use an observer:

Container(child: Observer(builder: (_) {
  var method;
  if (!controller.isDisabledButton) method = controller.methodController;
  return RaiseButton(child: Text('Test') onPressed: method);
}));

On the Controller:

@observable
bool isDisabledButton = true;

Then inside the control you can manipulate this variable as you want.

To keep the accordion nature intact when wanting to also use 'hide' and 'show' functions like .collapse( 'hide' ), you must initialize the collapsible panels with the parent property set in the object with toggle: false before making any calls to 'hide' or 'show'

// initialize collapsible panels
$('#accordion .collapse').collapse({
  toggle: false,
  parent: '#accordion'
});

// show panel one (will collapse others in accordion)
$( '#collapseOne' ).collapse( 'show' );

// show panel two (will collapse others in accordion)
$( '#collapseTwo' ).collapse( 'show' );

// hide panel two (will not collapse/expand others in accordion)
$( '#collapseTwo' ).collapse( 'hide' );

These are the sizes. Try to take a look in Supporting Mutiple Screens

320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
480dp: a tweener tablet like the Streak (480x800 mdpi).
600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

I use this to make more than one layout:

res/layout/main_activity.xml           # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml   # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml   # For 10” tablets (720dp wide and bigger)

For anchors, you should use title instead. alt is not valid atribute of a. See http://w3schools.com/tags/tag_a.asp

Build from the output directory

Instead of building from the top-level directory, build from the output directory. You can access the source directories by setting the vpath. This option has the advantage that the built-in rules can be used.

build.sh

#!/bin/bash
mkdir -p obj
cp Makefile.template obj/Makefile
cd obj
make "$*"

Makefile

.SUFFIXES:
.SUFFIXES: .c .o

CC=gcc 
CPPFLAGS=-Wall
LDLIBS=-lhpdf
VPATH=%.c ../src
VPATH=%.h ../src

objects=kumain.o kudlx.o kusolvesk.o kugetpuz.o kuutils.o \
  kurand.o kuASCboard.o kuPDFs.o kupuzstrings.o kugensud.o \
  kushapes.o

ku : $(objects)

$(objects) : ku.h kudefines.h kuglobals.h kufns.h

.PHONY: clean
clean :
  rm $(objects)

The disadvantage is that error messages do not match the CWD. This can be solved by skipping build.sh and directly building from the obj directory.

Another advantage of this approach is that it's somewhat popular. cmake works in a similar fashion.

Create Rule based on output option

The following solution isn't nice in my opinion, as I really love the built-in rules. However, GNU make doesn't support something like vpath for output directories. And the built-in rules cannot match, as the % in %.o would match obj/foo of obj/foo.o, leaving make with a search in vpath %.c src/ for stuff like src/obj/foo.c, but not src/foo.c.

But this is as close to the built-in rules as you can get, and therefore to my best knowledge the nicest solution that's available.

$(OBJDIR)/%.o: %.c
        $(COMPILE.c) $(OUTPUT_OPTION) $<

Explanation: $(COMPILE.c) $(OUTPUT_OPTION) $< actually is how .c.o is implemented, see http://git.savannah.gnu.org/cgit/make.git/tree/default.c (and it's even mentioned in the manual)

Besides, if $(OBJDIR) would only ever contain auto-gererated files, you could create it on-the-fly with an order-only prerequisite, making the clean rule slightly simpler:

$(OBJDIR):
        mkdir -p $(OBJDIR)

$(OBJDIR)/%.o: %.c | $(OBJDIR)
        $(COMPILE.c) $(OUTPUT_OPTION) $<

.PHONY: clean
clean:
        $(RM) -r $(OBJDIR)

This requires that the feature order-only is available, which you can check using $(filter order-only, $(.FETAURES)). I've checked on Kubuntu 14.04 GNU make 3.81 and OpenSUSE 13.1 GNU make 3.82. Both were built with order-only enabled, and am now left puzzled why Kubuntu 14.04 comes with an older version of GNU make than OpenSUSE 13.1. Anyways, gonna download make 4.1 now :)

I posted a fix for this here

You can use this function to modify JSON.stringify to encode arrays, just post it near the beginning of your script (check the link above for more detail):

// Upgrade for JSON.stringify, updated to allow arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

It looks like CLR / C# might be getting better support for Vector<> soon.

Yes you can solve this error by changing the port number of glassfish because the WAMP SERVER or ORACLE database software uses a port number 8080, so there is a conflict of port number.

1)open a path like C:\GlassFish_Server\glassfish\domains\domain1\config\domain.xml.

2)find out the 8080 port number with the help of ctrl+F. You will get the following code...

<network-listener protocol="http-listener-1" port="8080" name="http-listener-1" thread-pool="http-thread-pool" transport="tcp">

3) Change that port number from 8080 to 9090 or 1234 or whatever you like..

4) Save it. Open a Netbeans IDE goto the glassfish server .

5) Right click on the server -> select refresh option.

6) to check the port no. which is given by u just right click on the server-> property.

7) Start the Glassfish server . Yehhh the error is gone...

I was facing same issue while building some of project.

I used Visual Studio 2015 IDE, there it was working fine but while giving build from PowerShell script, it was giving toolset related "The builds tools for v140 (Platform Toolset = 'v140') cannot be found." error

So eventually it was issue of pointing to incorrect MSBUILD exe for the respective project.

Earlier I was pointing to $MSBUILD="C:\windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe

And build was successful when I updated script to point to $MSBUILD="C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe"

Hence to resolve the issue, please make sure to use correct MSBUILD.

Just use the below code. It will shadow surround the entire DIV

-webkit-box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);
-moz-box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);
box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);

Hope this will work

"val means immutable and var means mutable."

To paraphrase, "val means value and var means variable".

A distinction that happens to be extremely important in computing (because those two concepts define the very essence of what programming is all about), and that OO has managed to blur almost completely, because in OO, the only axiom is that "everything is an object". And that as a consequence, lots of programmers these days tend not to understand/appreciate/recognize, because they have been brainwashed into "thinking the OO way" exclusively. Often leading to variable/mutable objects being used like everywhere, when value/immutable objects might/would often have been better.

You can use SQL Compact Query Analyzer

http://sqlcequery.codeplex.com/

SQL Compact Query Analyzer is really snappy. 3 MB download, requires an install but really snappy and works.

The authority, as listed in android:authorities must be unique. Quoting the documentation for this attribute:

To avoid conflicts, authority names should use a Java-style naming convention (such as com.example.provider.cartoonprovider). Typically, it's the name of the ContentProvider subclass that implements the provider

For a valid JSON string at least a "{}" is required. See more at the http://json.org/

None of the intent flags worked for me, but this is how I fixed it:

When a user signs out from one activity I had to broadcast a message from that activity, then receive it in the activities that I wanted to close after which I call finish(); and it works pretty well.

To add a text to your ImageView you can do this:

<RelativeLayout> // Only works inside a RelativeLayout
    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/myImageSouce" />

    <TextView
        android:id="@+id/myImageViewText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/myImageView"
        android:layout_alignTop="@+id/myImageView"
        android:layout_alignRight="@+id/myImageView"
        android:layout_alignBottom="@+id/myImageView"
        android:layout_margin="1dp"
        android:gravity="center"
        android:text="Hello"
        android:textColor="#000000" />
 </RelativeLayout>

Here's a simple example of how to load JSON data into an Angular model.

I have a JSON 'GET' web service which returns a list of Customer details, from an online copy of Microsoft's Northwind SQL Server database.

http://www.iNorthwind.com/Service1.svc/getAllCustomers

It returns some JSON data which looks like this:

{ 
    "GetAllCustomersResult" : 
        [
            {
              "CompanyName": "Alfreds Futterkiste",
              "CustomerID": "ALFKI"
            },
            {
              "CompanyName": "Ana Trujillo Emparedados y helados",
              "CustomerID": "ANATR"
            },
            {
              "CompanyName": "Antonio Moreno Taquería",
              "CustomerID": "ANTON"
            }
        ]
    }

..and I want to populate a drop down list with this data, to look like this...

I want the text of each item to come from the "CompanyName" field, and the ID to come from the "CustomerID" fields.

How would I do it ?

My Angular controller would look like this:

function MikesAngularController($scope, $http) {

    $scope.listOfCustomers = null;

    $http.get('http://www.iNorthwind.com/Service1.svc/getAllCustomers')
         .success(function (data) {
             $scope.listOfCustomers = data.GetAllCustomersResult;
         })
         .error(function (data, status, headers, config) {
             //  Do some error handling here
         });
}

... which fills a "listOfCustomers" variable with this set of JSON data.

Then, in my HTML page, I'd use this:

<div ng-controller='MikesAngularController'>
    <span>Please select a customer:</span>
    <select ng-model="selectedCustomer" ng-options="customer.CustomerID as customer.CompanyName for customer in listOfCustomers" style="width:350px;"></select>
</div>

And that's it. We can now see a list of our JSON data on a web page, ready to be used.

The key to this is in the "ng-options" tag:

customer.CustomerID as customer.CompanyName for customer in listOfCustomers

It's a strange syntax to get your head around !

When the user selects an item in this list, the "$scope.selectedCustomer" variable will be set to the ID (the CustomerID field) of that Customer record.

The full script for this example can be found here:

JSON data with Angular

EDIT (02 Jan 2012):

I created a small open source Android Library Project that streamlines this process, while also providing a built-in file explorer (in case the user does not have one present). It's extremely simple to use, requiring only a few lines of code.

You can find it at GitHub: aFileChooser.

ORIGINAL

If you want the user to be able to choose any file in the system, you will need to include your own file manager, or advise the user to download one. I believe the best you can do is look for "openable" content in an Intent.createChooser() like this:

private static final int FILE_SELECT_CODE = 0;

private void showFileChooser() {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
    intent.setType("*/*"); 
    intent.addCategory(Intent.CATEGORY_OPENABLE);

    try {
        startActivityForResult(
                Intent.createChooser(intent, "Select a File to Upload"),
                FILE_SELECT_CODE);
    } catch (android.content.ActivityNotFoundException ex) {
        // Potentially direct the user to the Market with a Dialog
        Toast.makeText(this, "Please install a File Manager.", 
                Toast.LENGTH_SHORT).show();
    }
}

You would then listen for the selected file's Uri in onActivityResult() like so:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        case FILE_SELECT_CODE:
        if (resultCode == RESULT_OK) {
            // Get the Uri of the selected file 
            Uri uri = data.getData();
            Log.d(TAG, "File Uri: " + uri.toString());
            // Get the path
            String path = FileUtils.getPath(this, uri);
            Log.d(TAG, "File Path: " + path);
            // Get the file instance
            // File file = new File(path);
            // Initiate the upload
        }
        break;
    }
    super.onActivityResult(requestCode, resultCode, data);
}

The getPath() method in my FileUtils.java is:

public static String getPath(Context context, Uri uri) throws URISyntaxException {
    if ("content".equalsIgnoreCase(uri.getScheme())) {
        String[] projection = { "_data" };
        Cursor cursor = null;

        try {
            cursor = context.getContentResolver().query(uri, projection, null, null, null);
            int column_index = cursor.getColumnIndexOrThrow("_data");
            if (cursor.moveToFirst()) {
                return cursor.getString(column_index);
            }
        } catch (Exception e) {
            // Eat it
        }
    }
    else if ("file".equalsIgnoreCase(uri.getScheme())) {
        return uri.getPath();
    }

    return null;
} 

An easy, loop-free alternative is to use the horizontalalignment Text property as a keyword argument to xticks[1]. In the below, at the commented line, I've forced the xticks alignment to be "right".

n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]
fig, ax = plt.subplots()
ax.plot(x,y, 'o-')

plt.xticks(
        [0,1,2,3,4],
        ["this label extends way past the figure's left boundary",
        "bad motorfinger", "green", "in the age of octopus diplomacy", "x"], 
        rotation=45,
        horizontalalignment="right")    # here
plt.show()

(yticks already aligns the right edge with the tick by default, but for xticks the default appears to be "center".)

[1] You find that described in the xticks documentation if you search for the phrase "Text properties".

I have been looking at this. On populating the drop down anchors, I have given them a class and data attributes, so when needing to do an action you can do:

<li><a class="dropDownListItem" data-name="Fred Smith" href="#">Fred</a></li>

and then in the jQuery doing something like:

$('.dropDownListItem').click(function(e) {
    var name = e.currentTarget;
    console.log(name.getAttribute("data-name"));
});

So if you have dynamically generated list items in your dropdown and need to use the data that isn't just the text value of the item, you can use the data attributes when creating the dropdown listitem and then just give each item with the class the event, rather than referring to the id's of each item and generating a click event.

Use the ToString() method - standard and custom numeric format strings. Have a look at the MSDN article How to: Pad a Number with Leading Zeros.

string text = no.ToString("0000");

the shortest way

re.sub(r'http\S+', '', stringliteral)

I think the main benefit would be when you define your own Display Templates, or use Data annotations.

So for example if your title was a date, you could define

[DisplayFormat(DataFormatString = "{0:d}")]

and then on every page it would display the value in a consistent manner. Otherwise you may have to customise the display on multiple pages. So it does not help much for plain strings, but it does help for currencies, dates, emails, urls, etc.

For example instead of an email address being a plain string it could show up as a link:

<a href="mailto:@ViewData.Model">@ViewData.TemplateInfo.FormattedModelValue</a>

You can use ping -a <ip> or nbtstat -A <ip>

Use os.chdir. Here's a full example: https://colab.research.google.com/notebook#fileId=1CSPBdmY0TxU038aKscL8YJ3ELgCiGGju

Compactly:

!mkdir abc
!echo "file" > abc/123.txt

import os
os.chdir('abc')

# Now the directory 'abc' is the current working directory.
# and will show 123.txt.
!ls

I noticed that debug logs mention old version of firebase-analytics (16.0.0). Adding explicitly the latest version fixed the problem:

implementation "com.google.firebase:firebase-analytics:16.0.3"

I did the same thing with SQL Server 2012 and it worked

Insert into #table1 With (ROWLOCK) (Id, studentId, name)
SELECT '18769', '2', 'Alex'
WHERE not exists (select * from #table1 where Id = '18769' and studentId = '2')

Get to the registry to configuration of the client and change the LANG. For Oracle, go to HLM\SOFTWARE\ORACLE\KEY_ORACLIENT...HOME\NLS_LANG and change to appropriate language.

The parameter to the COUNT function is an expression that is to be evaluated for each row. The COUNT function returns the number of rows for which the expression evaluates to a non-null value. ( * is a special expression that is not evaluated, it simply returns the number of rows.)

There are two additional modifiers for the expression: ALL and DISTINCT. These determine whether duplicates are discarded. Since ALL is the default, your example is the same as count(ALL 1), which means that duplicates are retained.

Since the expression "1" evaluates to non-null for every row, and since you are not removing duplicates, COUNT(1) should always return the same number as COUNT(*).

It only comes when your list or dictionary not available in the local function.

Use sed's substitution: sed 's/"//g'

s/X/Y/ replaces X with Y.

g means all occurrences should be replaced, not just the first one.

For security reasons, your script cannot close a window/tab that it did not open.

The solution is to present the age prompt at an earlier point in the navigation history. Then, you can choose to allow them to enter your site or not based on their input.

Instead of closing the page that presents the prompt, you can simply say, "Sorry", or perhaps redirect the user to their homepage.

Also remember that it must be:

#include "stdafx.h"
#include <iostream>

and not the other way around

#include <iostream>
#include "stdafx.h"

Well, you can't check if it's down after the event, but you can check if it's Up... If it's up.. it means that no longer is down :P lol

So the user presses the button down (onMouseDown event) ... and after that, you check if is up (onMouseUp). While it's not up, you can do what you need.

As it is, both dimensions of your vector are 0.

Instead, initialize the vector as this:

vector<vector<int> > matrix(RR);
for ( int i = 0 ; i < RR ; i++ )
   matrix[i].resize(CC);

This will give you a matrix of dimensions RR * CC with all elements set to 0.

So here is the solution for this:

I check port 80 used by Skype, after that I changes port to 81 and also along with that somewhere i read this error may be because of SSL Port then I changed SSL port to 444. However this got resolved easily.

One most important thing to notice here, all the port changes should be done inside config files, for http port change: httpd.conf for SSL httpd-ssl.conf. Otherwise changes will not replicate to Apache, Sometime PC reboot is also required.

Edit: Make Apache use port 80 and make Skype communicate on other Port

For those who are struggling with Skype, want to change its port and to make Apache to use port 80.

No need to Re-Install, Here is simply how to change Skype Port

Goto: Tools > Options > Advanced > Connection

There you need to uncheck Use port 80 and 443 as alternative for incoming connections.

That's it, here is screen shot of it.

you can do it short like this:

matrix = [["A, B, C, D, E"]*5]
print(matrix)


[['A, B, C, D, E', 'A, B, C, D, E', 'A, B, C, D, E', 'A, B, C, D, E', 'A, B, C, D, E']]

Well, I'm a bit late but still would like to share my way of schema creation.

I have schemas for everything that can be described by a word, like you would do it in the classical OOP.

E.G.

• Comment
• Account
• User
• Blogpost
• ...

Every schema can be saved as a Document or Subdocument, so I declare this for each schema.

Document:

• Can be used as a reference. (E.g. the user made a comment -> comment has a "made by" reference to user)
• Is a "Root" in you application. (E.g. the blogpost -> there is a page about the blogpost)

Subdocument:

• Can only be used once / is never a reference. (E.g. Comment is saved in the blogpost)
• Is never a "Root" in you application. (The comment just shows up in the blogpost page but the page is still about the blogpost)

How I check in SSH.Run:

systemctl

If response: Failed to get D-Bus connection: Operation not permitted

Its a docker or WSL container.

My test string for the following:

testing='12345,abc,123,54321,ab15234,123456,52341';

If I understand your question, you'd want ["12345", "54321", "15234", "52341"].

If JS engines supported regexp lookbehinds, you could do:

testing.match(/(?<!\d)\d{5}(?!\d)/g)

Since it doesn't currently, you could:

testing.match(/(?:^|\D)(\d{5})(?!\d)/g)

and remove the leading non-digit from appropriate results, or:

pentadigit=/(?:^|\D)(\d{5})(?!\d)/g;
result = [];
while (( match = pentadigit.exec(testing) )) {
    result.push(match[1]);
}

Note that for IE, it seems you need to use a RegExp stored in a variable rather than a literal regexp in the while loop, otherwise you'll get an infinite loop.

You should use both title and alt attributes to make it work in all browsers.

<button title="Hello World!" alt="Hello World!">Sample Button</button>

If you just want to set the source of the image you can use this.

$("img").attr('src','http://somedomain.com/image.jpg');

To upload image with form fields

SaveFileWithData(article: ArticleModel,picture:File): Observable<ArticleModel> 
{

    let headers = new Headers();
    // headers.append('Content-Type', 'multipart/form-data');
    // headers.append('Accept', 'application/json');

let requestoptions = new RequestOptions({
  method: RequestMethod.Post,
  headers:headers
    });



let formData: FormData = new FormData();
if (picture != null || picture != undefined) {
  formData.append('files', picture, picture.name);
}
 formData.append("article",JSON.stringify(article));

return this.http.post("url",formData,requestoptions)
  .map((response: Response) => response.json() as ArticleModel);
} 

In my case I needed .NET Web Api in C#

// POST: api/Articles
[ResponseType(typeof(Article))]
public async Task<IHttpActionResult> PostArticle()
{
    Article article = null;
    try
    {

        HttpPostedFile postedFile = null;
        var httpRequest = HttpContext.Current.Request;

        if (httpRequest.Files.Count == 1)
        {
            postedFile = httpRequest.Files[0];
            var filePath = HttpContext.Current.Server.MapPath("~/" + postedFile.FileName);
            postedFile.SaveAs(filePath);
        }
        var json = httpRequest.Form["article"];
         article = JsonConvert.DeserializeObject <Article>(json);

        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        article.CreatedDate = DateTime.Now;
        article.CreatedBy = "Abbas";

        db.articles.Add(article);
        await db.SaveChangesAsync();
    }
    catch (Exception ex)
    {
        int a = 0;
    }
    return CreatedAtRoute("DefaultApi", new { id = article.Id }, article);
}

First of all, are they float or Float? If one of them is a Float, you should use the equals() method. Also, probably best to use the static Float.compare method.

Can work with infinite generators:

a.Zip(a.Skip(1), (x, y) => Enumerable.Repeat(x, 1).Concat(Enumerable.Repeat(y, 1)))
 .Zip(a.Skip(2), (xy, z) => xy.Concat(Enumerable.Repeat(z, 1)))
 .Where((x, i) => i % 3 == 0)

Demo code: https://ideone.com/GKmL7M

using System;
using System.Collections.Generic;
using System.Linq;

public class Test
{
  private static void DoIt(IEnumerable<int> a)
  {
    Console.WriteLine(String.Join(" ", a));

    foreach (var x in a.Zip(a.Skip(1), (x, y) => Enumerable.Repeat(x, 1).Concat(Enumerable.Repeat(y, 1))).Zip(a.Skip(2), (xy, z) => xy.Concat(Enumerable.Repeat(z, 1))).Where((x, i) => i % 3 == 0))
      Console.WriteLine(String.Join(" ", x));

    Console.WriteLine();
  }

  public static void Main()
  {
    DoIt(new int[] {1});
    DoIt(new int[] {1, 2});
    DoIt(new int[] {1, 2, 3});
    DoIt(new int[] {1, 2, 3, 4});
    DoIt(new int[] {1, 2, 3, 4, 5});
    DoIt(new int[] {1, 2, 3, 4, 5, 6});
  }
}

But actually I would prefer to write corresponding method without linq.

On a current netcat (v0.7.1) you have a -c switch:

-c, --close                close connection on EOF from stdin

Hence,

echo "hi" | nc -cu localhost 8000

should do the trick.

Apple provides detailed, illustrated instructions covering every step of the process. Log in to the iPhone developer site and click the "program portal" link. In the program portal you'll find a link to the program portal user's guide, which is a really good reference and guide on this topic.

Yes you can negate the test as SiegeX has already pointed out.

However you shouldn't use regular expressions for this - it can fail if your path contains special characters. Try this instead:

[[ ":$PATH:" != *":$1:"* ]]

(Source)

If none of these work, try getBaseContext(), instead of context or this.

I know the thread is old, but just in case...

User object:

public class User{

    private int _id;
    private String _name;

    public User(){
        this._id = 0;
        this._name = "";
    }

    public void setId(int id){
        this._id = id;
    }

    public int getId(){
        return this._id;
    }

    public void setName(String name){
        this._name = name;
    }

    public String getName(){
        return this._name;
    }
}

Custom Spinner Adapter (ArrayAdapter)

public class SpinAdapter extends ArrayAdapter<User>{

    // Your sent context
    private Context context;
    // Your custom values for the spinner (User)
    private User[] values;

    public SpinAdapter(Context context, int textViewResourceId,
            User[] values) {
        super(context, textViewResourceId, values);
        this.context = context;
        this.values = values;
    }

    @Override
    public int getCount(){
       return values.length;
    }

    @Override
    public User getItem(int position){
       return values[position];
    }

    @Override
    public long getItemId(int position){
       return position;
    }


    // And the "magic" goes here
    // This is for the "passive" state of the spinner
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // I created a dynamic TextView here, but you can reference your own  custom layout for each spinner item
        TextView label = (TextView) super.getView(position, convertView, parent);
        label.setTextColor(Color.BLACK);
        // Then you can get the current item using the values array (Users array) and the current position
        // You can NOW reference each method you has created in your bean object (User class)
        label.setText(values[position].getName());

        // And finally return your dynamic (or custom) view for each spinner item
        return label;
    }

    // And here is when the "chooser" is popped up
    // Normally is the same view, but you can customize it if you want
    @Override
    public View getDropDownView(int position, View convertView,
            ViewGroup parent) {
        TextView label = (TextView) super.getDropDownView(position, convertView, parent);
        label.setTextColor(Color.BLACK);
        label.setText(values[position].getName());

        return label;
    }
}

And the implementarion:

public class Main extends Activity {
    // You spinner view
    private Spinner mySpinner;
    // Custom Spinner adapter (ArrayAdapter<User>)
    // You can define as a private to use it in the all class
    // This is the object that is going to do the "magic"
    private SpinAdapter adapter;

        @Override
        public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Create the Users array
        // You can get this retrieving from an external source
        User[] users = new User[2];

        users[0] = new User();
        users[0].setId(1);
        users[0].setName("Joaquin");

        users[1] = new User();
        users[1].setId(2);
        users[1].setName("Alberto");

        // Initialize the adapter sending the current context
        // Send the simple_spinner_item layout
        // And finally send the Users array (Your data)
        adapter = new SpinAdapter(Main.this,
            android.R.layout.simple_spinner_item,
            users);
        mySpinner = (Spinner) findViewById(R.id.miSpinner);
        mySpinner.setAdapter(adapter); // Set the custom adapter to the spinner
        // You can create an anonymous listener to handle the event when is selected an spinner item
        mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view,
                    int position, long id) {
                // Here you get the current item (a User object) that is selected by its position
                User user = adapter.getItem(position);
                // Here you can do the action you want to...
                Toast.makeText(Main.this, "ID: " + user.getId() + "\nName: " + user.getName(),
                    Toast.LENGTH_SHORT).show();
            }
            @Override
            public void onNothingSelected(AdapterView<?> adapter) {  }
        });
    }
}

For Swift 3 it's pretty fast forward:

private func setMapRegion(for location: CLLocationCoordinate2D, animated: Bool)
{
    let viewRegion = MKCoordinateRegionMakeWithDistance(location, <#T##latitudinalMeters: CLLocationDistance##CLLocationDistance#>, <#T##longitudinalMeters: CLLocationDistance##CLLocationDistance#>)
    MapView.setRegion(viewRegion, animated: animated)
}

Just define the lat-, long-Meters <CLLocationDistance> and the mapView will fit the zoom level to your values.

Yes, it's safe to delete these, although it may force a dynamic recompilation of any .NET applications you run on the server.

int64_t is guaranteed by the C99 standard to be exactly 64 bits wide on platforms that implement it, there's no such guarantee for a long which is at least 32 bits so it could be more.

§7.18.1.3 Exact-width integer types 1 The typedef name intN_t designates a signed integer type with width N , no padding bits, and a two’s complement representation. Thus, int8_t denotes a signed integer type with a width of exactly 8 bits.

You are getting Floating point exception because Number % i, when i is 0:

int Is_Prime( int Number ){

  int i ;

  for( i = 0 ; i < Number / 2 ; i++ ){

    if( Number % i != 0 ) return -1 ;

  }

  return Number ;

}

Just start the loop at i = 2. Since i = 1 in Number % i it always be equal to zero, since Number is a int.

Here is a slight variation on Shimmy's one for collection of classes that already implement the well-known IComparable<T> interface. In this case, the "order by" selector is implicit.

The amount of hacks you would need to go through to completely hide the fact your site is built by Meteor.js is absolutely ridiculous. You would have to strip essentially all core functionality and just serve straight up html, completely defeating the purpose of using the framework anyway.

That being said, I suggest looking at buildwith.com

You enter a url, and it reveals a ton of information about a site. If you only need to "fool" engines like this, there may be simple solutions.

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

You could use Vi/Vim's Visual Block mode which is designed for stuff like this:

Ctrl-V  
Highlight first element in rows you want commented  
Shift-i  
#  
esc  

Uncomment would be:

Ctrl-V  
Highlight #'s  
d  
l  

This is vi's interactive way of doing this sort of thing rather than counting or reading line numbers.

Lastly, in Gvim you use ctrl-q to get into Visual Block mode rather than ctrl-v (because that's the shortcut for paste).

There are a few ways of passing data around to different routes. The most correct answer is, of course, query strings. You'll need to ensure that the values are properly encodeURIComponent and decodeURIComponent.

app.get('/category', function(req, res) {
  var string = encodeURIComponent('something that would break');
  res.redirect('/?valid=' + string);
});

You can snag that in your other route by getting the parameters sent by using req.query.

app.get('/', function(req, res) {
  var passedVariable = req.query.valid;
  // Do something with variable
});

For more dynamic way you can use the url core module to generate the query string for you:

const url = require('url');    
app.get('/category', function(req, res) {
    res.redirect(url.format({
       pathname:"/",
       query: {
          "a": 1,
          "b": 2,
          "valid":"your string here"
        }
     }));
 });

So if you want to redirect all req query string variables you can simply do

res.redirect(url.format({
       pathname:"/",
       query:req.query,
     });
 });

And if you are using Node >= 7.x you can also use the querystring core module

const querystring = require('querystring');    
app.get('/category', function(req, res) {
      const query = querystring.stringify({
          "a": 1,
          "b": 2,
          "valid":"your string here"
      });
      res.redirect('/?' + query);
 });

Another way of doing it is by setting something up in the session. You can read how to set it up here, but to set and access variables is something like this:

app.get('/category', function(req, res) {
  req.session.valid = true;
  res.redirect('/');
});

And later on after the redirect...

app.get('/', function(req, res) {
  var passedVariable = req.session.valid;
  req.session.valid = null; // resets session variable
  // Do something
});

There is also the option of using an old feature of Express, req.flash. Doing so in newer versions of Express will require you to use another library. Essentially it allows you to set up variables that will show up and reset the next time you go to a page. It's handy for showing errors to users, but again it's been removed by default. EDIT: Found a library that adds this functionality.

Hopefully that will give you a general idea how to pass information around in an Express application.

This solution has been working for me:

1. Run the app in the simulator
2. Open the system log (? + /)

This will dump out all of the debug data and also your NSLogs.

To filter just your NSLog statements:

1. Prefix each with a symbol, for example: NSLog(@"^ Test Log")
2. Filter the results using the search box on the top right, "^" in the case above

This is what you should get:

To get a list of the words that appear more than once together with how often they occur, use a combination of GROUP BY and HAVING:

SELECT word, COUNT(*) AS cnt
FROM words
GROUP BY word
HAVING cnt > 1

To find the number of words in the above result set, use that as a subquery and count the rows in an outer query:

SELECT COUNT(*)
FROM
(
    SELECT NULL
    FROM words
    GROUP BY word
    HAVING COUNT(*) > 1
) T1

If you want something that works well on windows there is a package called WinFoldersJava which wraps the native call to get the 'special' directories on Windows. We use it frequently and it works well.

The appearance and disappearance of a window for displaying text is a feature of how you are running the program, not of C++.

Run in a persistent command line environment, or include windowing support in your program, or use sleep or wait on input as shown in other answers.

1. Ctrl-D would delete a line
2. Ctrl-Z would undo deletion, with highlithing entire line
3. Ctrl-X/C cut or copy entire line

The advantage over Ctrl-Alt-Down followed by Ctrl-X suggested by other users is that it doesn't make eclipse think that the file was changed in any way. It's also faster and causes no problems even if the user has rotating screen issue with Ctrl-Alt-Down/Up keyboard shorcut. So there's no need to remap shorcuts for this.

Another way to go would be hitting Alt-Shift-Up until the entire line gets selected. If you've gone too far, of course you can select less with Alt-Shift-Down.

If you want the labels to be retained for the tooltip, but not displayed below the bars the following hack might be useful. I made this change for use on an private intranet application and have not tested it for efficiency or side-effects, but it did what I needed.

At about line 71 in chart.js add a property to hide the bar labels:

// Boolean - Whether to show x-axis labels
barShowLabels: true,

At about line 1500 use that property to suppress changing this.endPoint (it seems that other portions of the calculation code are needed as chunks of the chart disappeared or were rendered incorrectly if I disabled anything more than this line).

if (this.xLabelRotation > 0) {
    if (this.ctx.barShowLabels) {
        this.endPoint -= Math.sin(toRadians(this.xLabelRotation)) * originalLabelWidth + 3;
    } else {
        // don't change this.endPoint
    }
}

At about line 1644 use the property to suppress the label rendering:

if (ctx.barShowLabels) {    
    ctx.fillText(label, 0, 0);
}

I'd like to make this change to the Chart.js source but aren't that familiar with git and don't have the time to test rigorously so would rather avoid breaking anything.

It's worth pointing out that if you have multiple Gmail accounts, you may want to use the URL approach because you can customize which account to compose from.

e.g.

https://mail.google.com/mail/u/0/#inbox?compose=new   
https://mail.google.com/mail/u/1/#inbox?compose=new

Or if you know the email address you are sending from, replace the numeric index with the email address:

https://mail.google.com/mail/u/[email protected]/#inbox?compose=new

Different tools may interpret the meaning of @Nullable differently. For example, the Checker Framework and FindBugs handle @Nullable differently.

Wonderful answer! I needed to fill in the empty cells in a column where there were titles in cells that applied to the empty cells below until the next title cell.

I used your code above to develop the code that is below my example sheet here. I applied this code as a macro ctl/shft/D to rapidly run down the column copying the titles.

--- Example Spreadsheet ------------ Title1 is copied to rows 2 and 3; Title2 is copied to cells below it in rows 5 and 6. After the second run of the Macro the active cell is the Title3 cell.

 ' **row** **Column1**        **Column2**
 '    1     Title1         Data 1 for title 1
 '    2                    Data 2 for title 1
 '    3                    Data 3 for title 1
 '    4     Title2         Data 1 for title 2
 '    5                    Data 2 for title 2
 '    6                    Data 3 for title 2
 '    7   Title 3          Data 1 for title 3

----- CopyDown code ----------

Sub CopyDown()
Dim Lastrow As String, FirstRow As String, strtCell As Range
'
' CopyDown Macro
' Copies the current cell to any empty cells below it.   
'
' Keyboard Shortcut: Ctrl+Shift+D
'
    Set strtCell = ActiveCell
    FirstRow = strtCell.Address
' Lastrow is address of the *list* of empty cells
    Lastrow = Range(Selection, Selection.End(xlDown).Offset(-1, 0)).Address
'   MsgBox Lastrow
    Range(Lastrow).Formula = strtCell.Formula

    Range(Lastrow).End(xlDown).Select
 End Sub

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

I found simple solution which worked for me.

Make your fragment adapter extends FragmentStatePagerAdapter instead of FragmentPagerAdapter and override method onSave to return null

@Override
public Parcelable saveState()
{
    return null;
}

This prevent android from recreating fragment

One day later I found another and better solution.

Call setRetainInstance(true) for all your fragments and save references to them somewhere. I did that in static variable in my activity, because it's declared as singleTask and fragments can stay the same all the time.

This way android not recreate fragments but use same instances.

Thanks to Lincoln's comment below, I've changed this answer.

The following answer properly handles 8-bit ints at compile time. It doees, however, require C++17. If you don't have C++17, you'll have to do something else (e.g. provide overloads of this function, one for uint8_t and one for int8_t, or use something besides "if constexpr", maybe enable_if).

template< typename T >
std::string int_to_hex( T i )
{
    // Ensure this function is called with a template parameter that makes sense. Note: static_assert is only available in C++11 and higher.
    static_assert(std::is_integral<T>::value, "Template argument 'T' must be a fundamental integer type (e.g. int, short, etc..).");

    std::stringstream stream;
    stream << "0x" << std::setfill ('0') << std::setw(sizeof(T)*2) << std::hex;

    // If T is an 8-bit integer type (e.g. uint8_t or int8_t) it will be 
    // treated as an ASCII code, giving the wrong result. So we use C++17's
    // "if constexpr" to have the compiler decides at compile-time if it's 
    // converting an 8-bit int or not.
    if constexpr (std::is_same_v<std::uint8_t, T>)
    {        
        // Unsigned 8-bit unsigned int type. Cast to int (thanks Lincoln) to 
        // avoid ASCII code interpretation of the int. The number of hex digits 
        // in the  returned string will still be two, which is correct for 8 bits, 
        // because of the 'sizeof(T)' above.
        stream << static_cast<int>(i);
    }        
    else if (std::is_same_v<std::int8_t, T>)
    {
        // For 8-bit signed int, same as above, except we must first cast to unsigned 
        // int, because values above 127d (0x7f) in the int will cause further issues.
        // if we cast directly to int.
        stream << static_cast<int>(static_cast<uint8_t>(i));
    }
    else
    {
        // No cast needed for ints wider than 8 bits.
        stream << i;
    }

    return stream.str();
}

Original answer that doesn't handle 8-bit ints correctly as I thought it did:

Kornel Kisielewicz's answer is great. But a slight addition helps catch cases where you're calling this function with template arguments that don't make sense (e.g. float) or that would result in messy compiler errors (e.g. user-defined type).

template< typename T >
std::string int_to_hex( T i )
{
  // Ensure this function is called with a template parameter that makes sense. Note: static_assert is only available in C++11 and higher.
  static_assert(std::is_integral<T>::value, "Template argument 'T' must be a fundamental integer type (e.g. int, short, etc..).");

  std::stringstream stream;
  stream << "0x" 
         << std::setfill ('0') << std::setw(sizeof(T)*2) 
         << std::hex << i;

         // Optional: replace above line with this to handle 8-bit integers.
         // << std::hex << std::to_string(i);

  return stream.str();
}

I've edited this to add a call to std::to_string because 8-bit integer types (e.g. std::uint8_t values passed) to std::stringstream are treated as char, which doesn't give you the result you want. Passing such integers to std::to_string handles them correctly and doesn't hurt things when using other, larger integer types. Of course you may possibly suffer a slight performance hit in these cases since the std::to_string call is unnecessary.

Note: I would have just added this in a comment to the original answer, but I don't have the rep to comment.

def bubble_sort(li):
    l = len(li)
    tmp = None
    sorted_l = sorted(li)
    while (li != sorted_l):
        for ele in range(0,l-1):
            if li[ele] > li[ele+1]:
                tmp = li[ele+1]
                li[ele+1] = li [ele]
                li[ele] = tmp
    return li

Another possible cause: make sure you haven't accidentally given both of the projects the same assembly name in project properties.

A useful extension is to collect the results in a Dictionary for fast lookup (e.g. in a loop):

var resultDict = _dbContext.Projects
    .Where(p => p.Status == ProjectStatus.Active)
    .GroupBy(f => f.Country)
    .Select(g => new { country = g.Key, count = g.Count() })
    .ToDictionary(k => k.country, i => i.count);

Originally found here: http://www.snippetsource.net/Snippet/140/groupby-and-count-with-ef-in-c

Maybe it will help someone, but sometimes Name tag might be missing for a reference and it leads that assembly cannot be found when building with MSBuild. Make sure that Name tag is available for particular reference csproj file, for example,

    <ProjectReference Include="..\MyDependency1.csproj">
      <Project>{9A2D95B3-63B0-4D53-91F1-5EFB99B22FE8}</Project>
      <Name>MyDependency1</Name>
    </ProjectReference>

See sys.exit. That function will quit your program with the given exit status.

The error happens because of you are trying to map a numeric vector to data in geom_errorbar: GVW[1:64,3]. ggplot only works with data.frame.

In general, you shouldn't subset inside ggplot calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame and you will be able to plot everything in one call.

Here with a dplyr solution to summarise the data and compute the standard error beforehand.

library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
    summarise(mean = mean(value),se = sd(value) / sqrt(n()))

ggplot(d, aes(x = variable, y = mean, fill = Genotype)) + 
  geom_bar(position = position_dodge(), stat = "identity", 
      colour="black", size=.3) +
  geom_errorbar(aes(ymin = mean - se, ymax = mean + se), 
      size=.3, width=.2, position=position_dodge(.9)) +
  xlab("Time") +
  ylab("Weight [g]") +
  scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"), 
      labels = c("Knock-out", "Wild type")) +
  ggtitle("Effect of genotype on weight-gain") +
  scale_y_continuous(breaks = 0:20*4) +

He is trying find and display the duplicate rows in a table.

SELECT *, COUNT(*) AS NoOfOccurrences
FROM TableName GROUP BY *
HAVING COUNT(*) > 1

Do we have a simple way to accomplish this?

To check whether a process/command returned 0 or not, use the operators && == 0 or not == 0 ||:

Just add operator to your script:

execute_command && (

       echo\Return 0, with no execution error
) || (
        echo\Return non 0, something went wrong
     )

command && echo\Return 0 || echo\Return non 0

• For details on Operators' behavior see: Conditional Execution || && ...

You can do:

super.alphaMethod1();

Note, that super is a reference to the parent, but super() is it's constructor.

Open xampp application, then do the following:

1. go to: volumes,

2. click the [mount] button, and

3. finally click explore.

After Spending quite a bit of time looking into this, i came up with the solution for this; In this solution i am not using the Basic authentication but instead went with the oAuth authentication protocol. But to use Basic authentication you should be able to specify this in the "setHeaderRequest" with minimal changes to the rest of the code example. I hope this will be able to help someone else in the future:

var token_ // variable will store the token
var userName = "clientID"; // app clientID
var passWord = "secretKey"; // app clientSecret
var caspioTokenUrl = "https://xxx123.caspio.com/oauth/token"; // Your application token endpoint  
var request = new XMLHttpRequest(); 

function getToken(url, clientID, clientSecret) {
    var key;           
    request.open("POST", url, true); 
    request.setRequestHeader("Content-type", "application/json");
    request.send("grant_type=client_credentials&client_id="+clientID+"&"+"client_secret="+clientSecret); // specify the credentials to receive the token on request
    request.onreadystatechange = function () {
        if (request.readyState == request.DONE) {
            var response = request.responseText;
            var obj = JSON.parse(response); 
            key = obj.access_token; //store the value of the accesstoken
            token_ = key; // store token in your global variable "token_" or you could simply return the value of the access token from the function
        }
    }
}
// Get the token
getToken(caspioTokenUrl, userName, passWord);

If you are using the Caspio REST API on some request it may be imperative that you to encode the paramaters for certain request to your endpoint; see the Caspio documentation on this issue;

NOTE: encodedParams is NOT used in this example but was used in my solution.

Now that you have the token stored from the token endpoint you should be able to successfully authenticate for subsequent request from the caspio resource endpoint for your application

function CallWebAPI() {
    var request_ = new XMLHttpRequest();        
    var encodedParams = encodeURIComponent(params);
    request_.open("GET", "https://xxx123.caspio.com/rest/v1/tables/", true);
    request_.setRequestHeader("Authorization", "Bearer "+ token_);
    request_.send();
    request_.onreadystatechange = function () {
        if (request_.readyState == 4 && request_.status == 200) {
            var response = request_.responseText;
            var obj = JSON.parse(response); 
            // handle data as needed... 

        }
    }
} 

This solution does only considers how to successfully make the authenticated request using the Caspio API in pure javascript. There are still many flaws i am sure...

According to: https://docs.npmjs.com/files/folders

• Local install (default): puts stuff in ./node_modules of the current package root.
• Global install (with -g): puts stuff in /usr/local or wherever node is installed.
• Install it locally if you're going to require() it.
• Install it globally if you're going to run it on the command line. -> If you need both, then install it in both places, or use npm link.

prefix Configuration

The prefix config defaults to the location where node is installed. On most systems, this is /usr/local. On windows, this is the exact location of the node.exe binary.

The docs might be a little outdated, but they explain why global installs can end up in different directories:

(dev) go|c:\srv> npm config ls -l | grep prefix
; prefix = "C:\\Program Files\\nodejs" (overridden)
prefix = "C:\\Users\\bjorn\\AppData\\Roaming\\npm"

Based on the other answers, it may seem like the override is now the default location on Windows, and that I may have installed my office version prior to this override being implemented.

This also suggests a solution for getting all team members to have globals stored in the same absolute path relative to their PC, i.e. (run as Administrator):

mkdir %PROGRAMDATA%\npm
setx PATH "%PROGRAMDATA%\npm;%PATH%" /M
npm config set prefix %PROGRAMDATA%\npm

open a new cmd.exe window and reinstall all global packages.

Explanation (by lineno.):

1. Create a folder in a sensible location to hold the globals (Microsoft is adamant that you shouldn't write to ProgramFiles, so %PROGRAMDATA% seems like the next logical place.
2. The directory needs to be on the path, so use setx .. /M to set the system path (under HKEY_LOCAL_MACHINE). This is what requires you to run this in a shell with administrator permissions.
3. Tell npm to use this new path. (Note: folder isn't visible in %PATH% in this shell, so you must open a new window).

I don't think that you really want an iframe, do you?

Unless you're doing something weird, you should be getting your results back as JSON or (in the worst case) XML, right?

For your white box / extra space issue, try

style="display: none;"

instead of

style="visibility: hidden;"

Here's an example DataFrame which show this, it has duplicate values with the same index. The question is, do you want to aggregate these or keep them as multiple rows?

In [11]: df
Out[11]:
   0  1  2      3
0  1  2  a  16.86
1  1  2  a  17.18
2  1  4  a  17.03
3  2  5  b  17.28

In [12]: df.pivot_table(values=3, index=[0, 1], columns=2, aggfunc='mean')  # desired?
Out[12]:
2        a      b
0 1
1 2  17.02    NaN
  4  17.03    NaN
2 5    NaN  17.28

In [13]: df1 = df.set_index([0, 1, 2])

In [14]: df1
Out[14]:
           3
0 1 2
1 2 a  16.86
    a  17.18
  4 a  17.03
2 5 b  17.28

In [15]: df1.unstack(2)
ValueError: Index contains duplicate entries, cannot reshape

One solution is to reset_index (and get back to df) and use pivot_table.

In [16]: df1.reset_index().pivot_table(values=3, index=[0, 1], columns=2, aggfunc='mean')
Out[16]:
2        a      b
0 1
1 2  17.02    NaN
  4  17.03    NaN
2 5    NaN  17.28

Another option (if you don't want to aggregate) is to append a dummy level, unstack it, then drop the dummy level...

Use logging.exception from within the except: handler/block to log the current exception along with the trace information, prepended with a message.

import logging
LOG_FILENAME = '/tmp/logging_example.out'
logging.basicConfig(filename=LOG_FILENAME, level=logging.DEBUG)

logging.debug('This message should go to the log file')

try:
    run_my_stuff()
except:
    logging.exception('Got exception on main handler')
    raise

Now looking at the log file, /tmp/logging_example.out:

DEBUG:root:This message should go to the log file
ERROR:root:Got exception on main handler
Traceback (most recent call last):
  File "/tmp/teste.py", line 9, in <module>
    run_my_stuff()
NameError: name 'run_my_stuff' is not defined

The Date() object in javascript is not that smart really.

If you just focus on adding seconds it seems to handle things smoothly but if you try to add X number of seconds then add X number of minute and hours, etc, to the same Date object you end up in trouble. So I simply fell back to only using the setSeconds() method and converting my data into seconds (which worked fine).

If anyone can demonstrate adding time to a global Date() object using all the set methods and have the final time come out correctly I would like to see it but I get the sense that one set method is to be used at a time on a given Date() object and mixing them leads to a mess.

var vTime = new Date();

var iSecondsToAdd = ( iSeconds + (iMinutes * 60) + (iHours * 3600) + (iDays * 86400) );

vTime.setSeconds(iSecondsToAdd);

Here is some more documentation that may help:

You can use ::after to create a 0px-height block after the <h4>, which effectively moves anything after the <h4> to the next line:

h4 {_x000D_
  display: inline;_x000D_
}_x000D_
h4::after {_x000D_
  content: "";_x000D_
  display: block;_x000D_
}

<ul>_x000D_
  <li>_x000D_
    Text, text, text, text, text. <h4>Sub header</h4>_x000D_
    Text, text, text, text, text._x000D_
  </li>_x000D_
</ul>

When you called notify on the notification manager you gave it an id - that is the unique id you can use to access it later (this is from the notification manager:

notify(int id, Notification notification)

To cancel, you would call:

cancel(int id)

with the same id. So, basically, you need to keep track of the id or possibly put the id into a Bundle you add to the Intent inside the PendingIntent?

In my case my request object inherited from base object. Without knowingly I added a property with int? in my request object and my base object also has same property ( same name ) with int datatype. I noticed this and deleted the property which I added in request object and after that it worked fine.

@NoCanDo: You cannot create an array with different data types because java only supports variables with a specific data type or object. When you are creating an array, you are pulling together an assortment of similar variables -- almost like an extended variable. All of the variables must be of the same type therefore. Java cannot differentiate the data type of your variable unless you tell it what it is. Ex: int tells all your variables declared to it are of data type int. What you could do is create 3 arrays with corresponding information.

Now, a single index number gives you all the info for that book. Ex: All of your arrays with index number 0 ([0]) have information for book 1.

And it works, thanks @trichetriche. The problem was in my RequestOptions, apparently, you can not pass params or body to the RequestOptions while using the post. Removing one of them gives me an error, removing both and it works. Still no final solution to my problem, but I now have something to work with. Final working code.

public post(cmd: string, data: string): Observable<any> {

    const options = new RequestOptions({
      headers: this.getAuthorizedHeaders(),
      responseType: ResponseContentType.Json,
      withCredentials: false
    });

    console.log('Options: ' + JSON.stringify(options));

    return this.http.post(this.BASE_URL, JSON.stringify({
      cmd: cmd,
      data: data}), options)
      .map(this.handleData)
      .catch(this.handleError);
  }

Quoting directly from the help page for factor:

To transform a factor f to its original numeric values, as.numeric(levels(f))[f] is recommended and slightly more efficient than as.numeric(as.character(f)).

I would suggest creating a regex to do the job. You'll have to check for something like this: [a-zA-Z0-9+/=] You'll also have to check the length of the string. I'm not sure on this one, but i'm pretty sure if something gets trimmed (other than the padding "=") it would blow up.

Or better yet check out this stackoverflow question

There is only one correct answer to this and most systems get it wrong. Number of milliseconds since epoch, aka a 64 bit integer. Time Zone is a UI concern and has no business in the app layer or db layer. Why does your db care what time zone something is, when you know it's going to store it as a 64 bit integer then do the transformation calculations.

Strip out the extraneous bits and just treat dates as numbers up to the UI. You can use simple arithmetic operators to do queries and logic.

Here's the shortest way to merge two arrays.

 var array1 = [1,2,3]
 let array2 = [4,5,6]

Concatenate/merge them

array1 += array2
New value of array1 is [1,2,3,4,5,6]

This is solution for AWS JavaScript SDK users, it is almost same for other languages.

Result.data.Count will give you what you are looking for

 apigClient.getitemPost({}, body, {})

    .then(function(result){

        var dataoutput = result.data.Items[0];

        console.log(result.data.Count);
  }).catch( function(result){

});

I experienced a similar compound error, which required two solutions. In my case the technology stack was MVC/ ASP.NET / IIS/ JQuery. The server side was failing with a 500 error, and this was occurring before the request was handled by the controller making the debug on the server side difficult.

The following client side debug enabled me to determine the server error

In the $.ajax error call back, display the error detail to the console

  error: (error) => {
                     console.log(JSON.stringify(error));
   }

This at least, enabled me to view the initial server error

“The JSON request was too large to be serialized”

This was resolved in the client web.config

<appSettings>
    <add key="aspnet:MaxJsonDeserializerMembers" value="150000" />

However, the request still failed. But this time with a different error that I was now able to debug on the server side

“Request Entity too large”

This was resolved by adding the following to the service web.config

<configuration>
…
 <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferPoolSize="524288">
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"  />
        </binding>
      </basicHttpBinding>
    </bindings>

The configuration values may require further tuning, but at least it resolved the server errors caused by the ajax post.

Here's one way:

cout << '\a';

From C++ Character Constants:

Alert: \a

Also consider using Array(). From the Ruby Community Style Guide:

Use Array() instead of explicit Array check or [*var], when dealing with a variable you want to treat as an Array, but you're not certain it's an array.

# bad
paths = [paths] unless paths.is_a? Array
paths.each { |path| do_something(path) }

# bad (always creates a new Array instance)
[*paths].each { |path| do_something(path) }

# good (and a bit more readable)
Array(paths).each { |path| do_something(path) }

According to the Documentation :

MailMessage.To property - Returns MailAddressCollection that contains the list of recipients of this email message

Here MailAddressCollection has a in built method called

   public void Add(string addresses)

   1. Summary:
          Add a list of email addresses to the collection.

   2. Parameters:
          addresses: 
                *The email addresses to add to the System.Net.Mail.MailAddressCollection. Multiple
                *email addresses must be separated with a comma character (",").     

Therefore requirement in case of multiple recipients : Pass a string that contains email addresses separated by comma

In your case :

simply replace all the ; with ,

Msg.To.Add(toEmail.replace(";", ","));

For reference :

Since rc.5 you have to do something like

@NgModule({
    imports: [ BrowserModule],
    providers: [ HTTP_PROVIDERS ],  
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})
export default class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

if your exe happens to be a console app, you might be interested in reading the stdout and stderr -- for that, I'll humbly refer you to this example:

http://support.microsoft.com/default.aspx?scid=kb;EN-US;q190351

It's a bit of a mouthful of code, but I've used variations of this code to spawn and read.

My problem is possibly due to the hash got wrongly generated by the openssl itself, if anyone is facing similar problem using the method provided by the facebook android guide itself.

One way to deal with this is :

1. Get your sha1 using this tool :

keytool -exportcert -keystore path-to-debug-or-production-keystore -list -v

2. convert it to base64 using this tool

These are much much better references than w3schools (the most awful web reference ever made):

• How cookies work (quirksmode.org)
• MDN document.cookie

Examples derived from these references:

// sets the cookie cookie1
document.cookie = 'cookie1=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// sets the cookie cookie2 (cookie1 is *not* overwritten)
document.cookie = 'cookie2=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// remove cookie2
document.cookie = 'cookie2=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/'

The Mozilla reference even has a nice cookie library you can use.

The answer provided here works very well with respect to time as well as memory but a bit more complicated as it uses advanced python constructs such as yield. The simpler answer works well in practice but, the issue with that answer is that it may generate many spurious integers before actually constructing the required set. Try it out with populationSize = 1000, sampleSize = 999. In theory, there is a chance that it doesn't terminate.

The answer below addresses both issues, as it is deterministic and somewhat efficient though currently not as efficient as the other two.

def randomSample(populationSize, sampleSize):
  populationStr = str(populationSize)
  dTree, samples = {}, []
  for i in range(sampleSize):
    val, dTree = getElem(populationStr, dTree, '')
    samples.append(int(val))
  return samples, dTree

where the functions getElem, percolateUp are as defined below

import random

def getElem(populationStr, dTree, key):
  msd  = int(populationStr[0])
  if not key in dTree.keys():
    dTree[key] = range(msd + 1)
  idx = random.randint(0, len(dTree[key]) - 1)
  key = key +  str(dTree[key][idx])
  if len(populationStr) == 1:
    dTree[key[:-1]].pop(idx)
    return key, (percolateUp(dTree, key[:-1]))
  newPopulation = populationStr[1:]
  if int(key[-1]) != msd:
    newPopulation = str(10**(len(newPopulation)) - 1)
  return getElem(newPopulation, dTree, key)

def percolateUp(dTree, key):
  while (dTree[key] == []):
    dTree[key[:-1]].remove( int(key[-1]) )
    key = key[:-1]
  return dTree

Finally, the timing on average was about 15ms for a large value of n as shown below,

In [3]: n = 10000000000000000000000000000000

In [4]: %time l,t = randomSample(n, 5)
Wall time: 15 ms

In [5]: l
Out[5]:
[10000000000000000000000000000000L,

You should be able to cite at least one from the JDK itself. Look in the java.util.collections package. There are several abstract classes. You should fully understand interface, abstract, and concrete for Map and why Joshua Bloch wrote it that way.

Also, when you uninstall the package, the first item listed is the directory to the executable.

A hard reset will also resolve the problem

git reset --hard origin/master

Try this one it will work

public class Third extends ListActivity {
private ArrayAdapter<String> adapter;
private List<String> liste;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third);
     String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2" };
     liste = new ArrayList<String>();
     Collections.addAll(liste, values);
     adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, liste);
     setListAdapter(adapter);
}
 @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
     liste.add("Nokia");
     adapter.notifyDataSetChanged();
  }
}

XMLReader is well documented on PHP site. This is a XML Pull Parser, which means it's used to iterate through nodes (or DOM Nodes) of given XML document. For example, you could go through the entire document you gave like this:

<?php
$reader = new XMLReader();
if (!$reader->open("data.xml"))
{
    die("Failed to open 'data.xml'");
}
while($reader->read())
{
    $node = $reader->expand();
    // process $node...
}
$reader->close();
?>

It is then up to you to decide how to deal with the node returned by XMLReader::expand().

There are pretty limited scenarios that I can think of where this would be useful, but let's assume you can't get funds to purchase VS2012 or something to that effect. If that's the case and you have Windows 7+ and VS 2010 you may be able to use the following hack I put together which seems to work (but I haven't fully deployed an application using this method yet).

1. Backup your project file!!!

2. Download and install the Windows 8 SDK which includes the .NET 4.5 SDK.

3. Open your project in VS2010.

4. Create a text file in your project named Compile_4_5_CSharp.targets with the following contents. (Or just download it here - Make sure to remove the ".txt" extension from the file name):

   <Project DefaultTargets="Build"
    xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
   
       <!-- Change the target framework to 4.5 if using the ".NET 4.5" configuration -->
       <PropertyGroup Condition=" '$(Platform)' == '.NET 4.5' ">
           <DefineConstants Condition="'$(DefineConstants)'==''">
               TARGETTING_FX_4_5
           </DefineConstants>
           <DefineConstants Condition="'$(DefineConstants)'!='' and '$(DefineConstants)'!='TARGETTING_FX_4_5'">
               $(DefineConstants);TARGETTING_FX_4_5
           </DefineConstants>
           <PlatformTarget Condition="'$(PlatformTarget)'!=''"/>
           <TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
       </PropertyGroup>
   
       <!-- Import the standard C# targets -->
       <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
   
       <!-- Add .NET 4.5 as an available platform -->
       <PropertyGroup>
          <AvailablePlatforms>$(AvailablePlatforms),.NET 4.5</AvailablePlatforms>
       </PropertyGroup>
   </Project>
   

5. Unload your project (right click -> unload).

6. Edit the project file (right click -> Edit *.csproj).

7. Make the following changes in the project file:

   a. Replace the default Microsoft.CSharp.targets with the target file created in step 4

   <!-- Old Import Entry -->
   <!-- <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" /> -->
   
   <!-- New Import Entry -->
   <Import Project="Compile_4_5_CSharp.targets" />
   

   b. Change the default platform to .NET 4.5

   <!-- Old default platform entry -->
   <!-- <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform> -->
   
   <!-- New default platform entry -->
   <Platform Condition=" '$(Platform)' == '' ">.NET 4.5</Platform>
   

   c. Add AnyCPU platform to allow targeting other frameworks as specified in the project properties. This should be added just before the first <ItemGroup> tag in the file

   <PropertyGroup Condition="'$(Platform)' == 'AnyCPU'">
       <PlatformTarget>AnyCPU</PlatformTarget>
   </PropertyGroup>
   
   .
   .
   .
   <ItemGroup>
   .
   .
   .
   

8. Save your changes and close the *.csproj file.

9. Reload your project (right click -> Reload Project).

10. In the configuration manager (Build -> Configuration Manager) make sure the ".NET 4.5" platform is selected for your project.

11. Still in the configuration manager, create a new solution platform for ".NET 4.5" (you can base it off "Any CPU") and make sure ".NET 4.5" is selected for the solution.

12. Build your project and check for errors.

13. Assuming the build completed you can verify that you are indeed targeting 4.5 by adding a reference to a 4.5 specific class to your source code:

    using System;
    using System.Text;
    
    namespace testing
    {
        using net45check = System.Reflection.ReflectionContext;
    }
    

14. When you compile using the ".NET 4.5" platform the build should succeed. When you compile under the "Any CPU" platform you should get a compiler error:

    Error 6: The type or namespace name 'ReflectionContext' does not exist in
    the namespace 'System.Reflection' (are you missing an assembly reference?)
    

JD-GUI is really good. You could just open a JAR file and browse through the code as if you are working on an IDE. Good stuff.

Here is @Scott Langham's answer with simple NULL handling:

SELECT
      o.OrderId,
      CASE WHEN (o.NegotiatedPrice > o.SuggestedPrice OR o.SuggestedPrice IS NULL) 
         THEN o.NegotiatedPrice 
         ELSE o.SuggestedPrice
      END As MaxPrice
FROM Order o

I guess something like this would work:

Add System.ServiceProcess to your project references (It's on the .NET tab).

using System.ServiceProcess;

ServiceController sc = new ServiceController(SERVICENAME);

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        return "Running";
    case ServiceControllerStatus.Stopped:
        return "Stopped";
    case ServiceControllerStatus.Paused:
        return "Paused";
    case ServiceControllerStatus.StopPending:
        return "Stopping";
    case ServiceControllerStatus.StartPending:
        return "Starting";
    default:
        return "Status Changing";
}

Edit: There is also a method sc.WaitforStatus() that takes a desired status and a timeout, never used it but it may suit your needs.

Edit: Once you get the status, to get the status again you will need to call sc.Refresh() first.

Reference: ServiceController object in .NET.

It failed because there is no server install on your computer. You need to Download 'MySQL Community Server 8.0.17' & restart your server.

If you are using MAC BOOK, this option is available inside Applications -> Right click Android Studio then choose Show Package contents -> bin.

or

open -e /Applications/Android\ Studio.app/Contents/bin/studio.vmoptions

Then increase Xmx value

-Xms128m
-Xmx2048m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=64m
-XX:+UseCodeCacheFlushing
-XX:+UseCompressedOops

Now your Android Studio will be super-fast.

I faced this issue because of lower version of Jdk. Previously I installed Jdk 1.7 and Android Studio 1.5.1, I got this issue. If you install Android Studio 1.5.1 or above JDK 1.8 required

So Installing JDK 1.8 solved this issue.

You can use the following format to generate a tooltip for an image.

<div class="tooltip"><img src="joe.jpg" />
  <span class="tooltiptext">Tooltip text</span>
</div>

This will depend on the logging configuration. The default value will depend on the framework being used. The idea is that later on by changing a configuration setting from INFO to DEBUG you will see a ton of more (or less if the other way around) lines printed without recompiling the whole application.

If you think which one to use then it boils down to thinking what you want to see on which level. For other levels for example in Log4J look at the API, http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html

Swift version :

var rootViewController = self.navigationController?.viewControllers.first

ObjectiveC version :

UIViewController *rootViewController = [self.navigationController.viewControllers firstObject];

Where self is an instance of a UIViewController embedded in a UINavigationController.

SOLVED

1. Just run CMD as an administrator.
2. Make sure your using the correct truststore password

It's simple. Do this, in your Manifest file.
