As Ben said, you'll need to work with the UIView's layer, using a CATransform3D to perform the layer's rotation. The trick to get perspective working, as described here, is to directly access one of the matrix cells of the CATransform3D (m34). Matrix math has never been my thing, so I can't explain exactly why this works, but it does. You'll need to set this value to a negative fraction for your initial transform, then apply your layer rotation transforms to that. You should also be able to do the following:

Objective-C

UIView *myView = [[self subviews] objectAtIndex:0];
CALayer *layer = myView.layer;
CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity;
rotationAndPerspectiveTransform.m34 = 1.0 / -500;
rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, 45.0f * M_PI / 180.0f, 0.0f, 1.0f, 0.0f);
layer.transform = rotationAndPerspectiveTransform;

Swift 5.0

if let myView = self.subviews.first {
    let layer = myView.layer
    var rotationAndPerspectiveTransform = CATransform3DIdentity
    rotationAndPerspectiveTransform.m34 = 1.0 / -500
    rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, 45.0 * .pi / 180.0, 0.0, 1.0, 0.0)
    layer.transform = rotationAndPerspectiveTransform
}

which rebuilds the layer transform from scratch for each rotation.

A full example of this (with code) can be found here, where I've implemented touch-based rotation and scaling on a couple of CALayers, based on an example by Bill Dudney. The newest version of the program, at the very bottom of the page, implements this kind of perspective operation. The code should be reasonably simple to read.

The sublayerTransform you refer to in your response is a transform that is applied to the sublayers of your UIView's CALayer. If you don't have any sublayers, don't worry about it. I use the sublayerTransform in my example simply because there are two CALayers contained within the one layer that I'm rotating.

Check out the example project on GitHub to make sure you use the component correctly.

Simple Swift 5 solution without any additional subviews or subclassing:

extension UIView {

    func addShadow(offset: CGSize, color: UIColor, radius: CGFloat, opacity: Float) {
        layer.masksToBounds = false
        layer.shadowOffset = offset
        layer.shadowColor = color.cgColor
        layer.shadowRadius = radius
        layer.shadowOpacity = opacity

        let backgroundCGColor = backgroundColor?.cgColor
        backgroundColor = nil
        layer.backgroundColor =  backgroundCGColor
    }
}

Note that you should set up your view with corner radius and other properties before calling addShadow.

After that, just call this from viewDidLoad like this:

button.addShadow(offset: CGSize.init(width: 0, height: 3), color: UIColor.black, radius: 2.0, opacity: 0.35)

Final result:

Super easy and simple!

For a simple and effective PDF viewer, when you require only limited functionality, you can now (iOS 4.0+) use the QuickLook framework:

First, you need to link against QuickLook.framework and #import <QuickLook/QuickLook.h>;

Afterwards, in either viewDidLoad or any of the lazy initialization methods:

QLPreviewController *previewController = [[QLPreviewController alloc] init];
previewController.dataSource = self;
previewController.delegate = self;
previewController.currentPreviewItemIndex = indexPath.row;
[self presentModalViewController:previewController animated:YES];
[previewController release];

Use this query to create the new table with the values from existing table

CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name; 

Now you can get all the values from existing table into newly created table.

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

Try

byte[] incomingByteArray = receive...; // This is your Base64-encoded bute[]

byte[] decodedByteArray =Convert.FromBase64String (Encoding.ASCII.GetString (incomingByteArray)); 
// This work because all Base64-encoding is done with pure ASCII characters

CREATE TABLE `voting` (
  `QuestionID` int(10) unsigned NOT NULL,
  `MemberId` int(10) unsigned NOT NULL,
  `vote` int(10) unsigned NOT NULL,
  PRIMARY KEY  (`QuestionID`,`MemberId`)
);

delete operator is used to remove an object property.

delete operator does not returns the new object, only returns a boolean: true or false.

In the other hand, after interpreter executes var updatedjsonobj = delete myjsonobj['otherIndustry']; , updatedjsonobj variable will store a boolean value.

How to remove Json object specific key and its value ?

You just need to know the property name in order to delete it from the object's properties.

delete myjsonobj['otherIndustry'];

let myjsonobj = {
  "employeeid": "160915848",
  "firstName": "tet",
  "lastName": "test",
  "email": "[email protected]",
  "country": "Brasil",
  "currentIndustry": "aaaaaaaaaaaaa",
  "otherIndustry": "aaaaaaaaaaaaa",
  "currentOrganization": "test",
  "salary": "1234567"
}
delete myjsonobj['otherIndustry'];
console.log(myjsonobj);

If you want to remove a key when you know the value you can use Object.keys function which returns an array of a given object's own enumerable properties.

let value="test";
let myjsonobj = {
      "employeeid": "160915848",
      "firstName": "tet",
      "lastName": "test",
      "email": "[email protected]",
      "country": "Brasil",
      "currentIndustry": "aaaaaaaaaaaaa",
      "otherIndustry": "aaaaaaaaaaaaa",
      "currentOrganization": "test",
      "salary": "1234567"
}
Object.keys(myjsonobj).forEach(function(key){
  if (myjsonobj[key] === value) {
    delete myjsonobj[key];
  }
});
console.log(myjsonobj);

>>> a = np.random.randint(0, 5, size=(5, 4))
>>> a
array([[0, 3, 3, 2],
       [4, 1, 1, 2],
       [3, 4, 2, 4],
       [2, 4, 3, 0],
       [1, 2, 3, 4]])
>>> 
>>> a[a > 3] = -101
>>> a
array([[   0,    3,    3,    2],
       [-101,    1,    1,    2],
       [   3, -101,    2, -101],
       [   2, -101,    3,    0],
       [   1,    2,    3, -101]])
>>>

See, eg, Indexing with boolean arrays.

That looks like it might belong in the select statement:

SELECT id, col1, col2, col3, (CASE WHEN table3.col3 IS NULL THEN table2.col3 AS col4 ELSE table3.col3 as col4 END)
FROM table1
LEFT OUTER JOIN table2
ON table1.id = table2.id
LEFT OUTER JOIN table3
ON table1.id = table3.id

Your cells object is not fully qualified. You need to add a DOT before the cells object. For example

With Worksheets("Cable Cards")
    .Range(.Cells(RangeStartRow, RangeStartColumn), _
           .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

Similarly, fully qualify all your Cells object.

You can also use redirect() method like this:-

return redirect('https://stackoverflow.com/');

While this seems to work

Code::query()
    ->where('to_be_used_by_user_id', '!=' , 2)
    ->orWhereNull('to_be_used_by_user_id')
    ->get();

you should not use it for big tables, because as a general rule "or" in your where clause is stopping query to use index. You are going from "Key lookup" to "full table scan"

Instead, try Union

$first = Code::whereNull('to_be_used_by_user_id');

$code = Code::where('to_be_used_by_user_id', '!=' , 2)
        ->union($first)
        ->get();

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(20, 30, 300, 50)];
label.backgroundColor = [UIColor clearColor];
label.textAlignment = NSTextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.numberOfLines = 0;
label.lineBreakMode = UILineBreakModeWordWrap;
label.text = @"Your Text";
[self.view addSubview:label];

Go to Run (WINDOWS + R) and Type shell:startup, paste your .bat file there !

Yeah, I had the same question for a long time and I found the perfect one. Here are some parameters from it.

https://maps.google.com/?parameter=value

q=

Used to specify the search query in Google maps search.
eg :

https://maps.google.com/?q=newyork or
https://maps.google.com/?q=51.03841,-114.01679

near=

Used to specify the location instead of putting it into q. Also has the added effect of allowing you to increase the AddressDetails Accuracy value by being more precise. Mostly only useful if q is a business or suchlike.

z=

Zoom level. Can be set 19 normally, but in certain cases can go up to 23.

ll=

Latitude and longitude of the map centre point. Must be in that order. Requires decimal format. Interestingly, you can use this without q, in which case it doesn’t show a marker.

sll=

Similar to ll, only this sets the lat/long of the centre point for a business search. Requires the same input criteria as ll.

t=

Sets the kind of map shown. Can be set to:

m – normal  map
k – satellite
h – hybrid
p – terrain

saddr=

Sets the starting point for directions searches. You can also add text into this in brackets to bold it in the directions sidebar.

daddr=

Sets the end point for directions searches, and again will bold any text added in brackets.You can also add "+to:" which will set via points. These can be added multiple times.

via=

Allows you to insert via points in directions. Must be in CSV format. For example, via=1,5 addresses 1 and 5 will be via points without entries in the sidebar. The start point (which is set as 0), and 2, 3 and 4 will all show full addresses.

doflg=

Changes the units used to measure distance (will default to the standard unit in country of origin). Change to ptk for metric or ptm for imperial.

msa=

Does stuff with My Maps. Set to 0 show defined My Maps, b to turn the My Maps sidebar on, 1 to show the My Maps tab on its own, or 2 to go to the new My Map creator form.

This worked for me...

<asp:RadioButtonList runat="server" ID="Intent">
  <asp:ListItem Value="Confirm">Yes!</asp:ListItem>
  <asp:ListItem Value="Postpone">Not now</asp:ListItem>
  <asp:ListItem Value="Decline">Never!</asp:ListItem>
</asp:RadioButtonList>

The handler:

$(document).ready(function () {
  $("#<%=Intent.ClientID%>").change(function(){
   var rbvalue = $("input[name='<%=Intent.UniqueID%>']:radio:checked").val();

   if(rbvalue == "Confirm"){
    alert("Woohoo, Thanks!");
   } else if (rbvalue == "Postpone"){
    alert("Well, I really hope it's soon");
   } else if (rbvalue == "Decline"){
    alert("Shucks!");
   } else {
    alert("How'd you get here? Who sent you?");
   }
  });
});

The important part: $("input[name='<%=Intent.UniqueID%>']:radio:checked").val();

You can just do:

git rev-parse HEAD

To explain a bit further: git rev-parse is git's basic command for interpreting any of the exotic ways that you can specify the name of a commit and HEAD is a reference to your current commit or branch. (In a git bisect session, it points directly to a commit ("detached HEAD") rather than a branch.)

Alternatively (and easier to remember) would be to just do:

git show

... which defaults to showing the commit that HEAD points to. For a more concise version, you can do:

$ git show --oneline -s
c0235b7 Autorotate uploaded images based on EXIF orientation

To Configure exception handling behavior per exception type you can use Middleware from NuGet packages:

• Community.AspNetCore.ExceptionHandling.NewtonsoftJson for ASP.NET Core 2.0
• Community.AspNetCore.ExceptionHandling.Mvc for ASP.NET Core 2.1+.

Code sample:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    services.AddExceptionHandlingPolicies(options =>
    {
        options.For<InitializationException>().Rethrow();

        options.For<SomeTransientException>().Retry(ro => ro.MaxRetryCount = 2).NextPolicy();

        options.For<SomeBadRequestException>()
        .Response(e => 400)
            .Headers((h, e) => h["X-MyCustomHeader"] = e.Message)
            .WithBody((req,sw, exception) =>
                {
                    byte[] array = Encoding.UTF8.GetBytes(exception.ToString());
                    return sw.WriteAsync(array, 0, array.Length);
                })
        .NextPolicy();

        // Ensure that all exception types are handled by adding handler for generic exception at the end.
        options.For<Exception>()
        .Log(lo =>
            {
                lo.EventIdFactory = (c, e) => new EventId(123, "UnhandlerException");
                lo.Category = (context, exception) => "MyCategory";
            })
        .Response(null, ResponseAlreadyStartedBehaviour.GoToNextHandler)
            .ClearCacheHeaders()
            .WithObjectResult((r, e) => new { msg = e.Message, path = r.Path })
        .Handled();
    });
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseExceptionHandlingPolicies();
    app.UseMvc();
}

C++ compilers process their input once. Each class you use must have been defined first. You use MyMessageBox before you define it. In this case, you can simply swap the two class definitions.

you can also used findOrFail() method here it's good to used

if the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these method not give a 500 error..

ModelName::findOrFail($id, ['firstName', 'lastName']);

A dynamic_cast performs a type checking using RTTI. If it fails it'll throw you an exception (if you gave it a reference) or NULL if you gave it a pointer.

Depending on which browser you need to support, there's the option of MutationObserver.

EDIT: All major browsers support MutationObserver now.

Something along the lines of this should do the trick:

// callback executed when canvas was found
function handleCanvas(canvas) { ... }

// set up the mutation observer
var observer = new MutationObserver(function (mutations, me) {
  // `mutations` is an array of mutations that occurred
  // `me` is the MutationObserver instance
  var canvas = document.getElementById('my-canvas');
  if (canvas) {
    handleCanvas(canvas);
    me.disconnect(); // stop observing
    return;
  }
});

// start observing
observer.observe(document, {
  childList: true,
  subtree: true
});

N.B. I haven't tested this code myself, but that's the general idea.

You can easily extend this to only search the part of the DOM that changed. For that, use the mutations argument, it's an array of MutationRecord objects.

So let's say you have a local branch foo, a remote called origin and a remote branch origin/master.

To push the contents of foo to origin/master, you first need to set its upstream:

git checkout foo
git branch -u origin/master

Then you can push to this branch using:

git push origin HEAD:master

In the last command you can add --force to replace the entire history of origin/master with that of foo.

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

I resized images as above and updated ios platform and cordova-plugin-splashscreen to latest and the flash to white screen after a second issue was fixed. However the initial spash image has a white border at bottom now.

In addition to the nested scrolling NestedScrollView added one major functionality, which could even make it interesting outside of nested contexts: It has build in support for OnScrollChangeListener. Adding a OnScrollChangeListener to the original ScrollView below API 23 required subclassing ScrollView or messing around with the ViewTreeObserver of the ScrollView which often means even more work than subclassing. With NestedScrollView it can be done using the build-in setter.

... is syntax for variadic arguments.

I think it is implemented by the complier using slice ([]Type), just like the function append :

func append(slice []Type, elems ...Type) []Type

when you use "elems" in "append", actually it is a slice([]type). So "a = append(a[:0], a[1:]...)" means "a = append(a[0:0], a[1:])"

a[0:0] is a slice which has nothing

a[1:] is "Hello2 Hello3"

This is how it works

Just an update to the Java 8 version

public Map<String, List<String>> splitQuery(URL url) {
    if (Strings.isNullOrEmpty(url.getQuery())) {
        return Collections.emptyMap();
    }
    return Arrays.stream(url.getQuery().split("&"))
            .map(this::splitQueryParameter)
            .collect(Collectors.groupingBy(SimpleImmutableEntry::getKey, LinkedHashMap::new, **Collectors**.mapping(Map.Entry::getValue, **Collectors**.toList())));
}

mapping and toList() methods have to be used with Collectors which was not mentioned in the top answer. Otherwise it would throw compilation error in IDE

There wasn't any luck here with the other answers, but I managed to work it out with this nice one-liner:

You can add jar doing:

For gradle just put following code in build.gradle:

dependencies {
...
compile fileTree(dir: 'lib', includes: ['suitetalk-*0.jar'])
...
}

and for maven just follow steps:

For Intellij: File->project structure->modules->dependency tab-> click on + sign-> jar and dependency->select jars you want to import-> ok-> apply(if visible)->ok

Remember that if you got any java.lang.NoClassDefFoundError: Could not initialize class exception at runtime this means that dependencies in jar not installed for that you have to add all dependecies in parent project.

If you are getting the query in your output you need to show us the code that actually echos the result. Can you post the code that calls requeteSQL?

For example, if you have used single quotes in php, it will print the variable name, not the value

echo 'foo is $foo'; // foo is $foo

This sounds exactly like your problem and I am positive this is the cause.

Also, try removing the @ symbol to see if that helps by giving you more infromation.

so that

$SQL_result = @mysql_query($SQL_requete); // run the query

becomes

  $SQL_result = mysql_query($SQL_requete); // run the query

This will stop any error suppression if the query is throwing an error.

You could create a new List and addAll() of your other Lists to it. Then return an unmodifiable list with Collections.unmodifiableList().

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

ThiefMaster's answer is 100% correct, although I came across a similar problem where I needed to fetch a property from a nested object (object within an object), so as an alternative to his answer, you can create a recursive solution that will allow you to define a nomenclature to grab any property, regardless of depth:

function fetchFromObject(obj, prop) {

    if(typeof obj === 'undefined') {
        return false;
    }

    var _index = prop.indexOf('.')
    if(_index > -1) {
        return fetchFromObject(obj[prop.substring(0, _index)], prop.substr(_index + 1));
    }

    return obj[prop];
}

Where your string reference to a given property ressembles property1.property2

You can't wait() on an object unless the current thread owns that object's monitor. To do that, you must synchronize on it:

class Runner implements Runnable
{
  public void run()
  {
    try
    {
      synchronized(Main.main) {
        Main.main.wait();
      }
    } catch (InterruptedException e) {}
    System.out.println("Runner away!");
  }
}

The same rule applies to notify()/notifyAll() as well.

The Javadocs for wait() mention this:

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Throws:

IllegalMonitorStateException – if the current thread is not the owner of this object's monitor.

And from notify():

A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

You can use pandas.Dataframe.isin.

pandas.Dateframe.isin will return boolean values depending on whether each element is inside the list a or not. You then invert this with the ~ to convert True to False and vice versa.

You can use extensions for this.

extension NSDate {
    //NSString to NSDate
    convenience
    init(dateString:String) {
        let nsDateFormatter = NSDateFormatter()
        nsDateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
        // Add the locale if required here
        let dateObj = nsDateFormatter.dateFromString(dateString)
        self.init(timeInterval:0, sinceDate:dateObj!)
    }

    //NSDate to time string
    func getTime() -> String {
        let timeFormatter = NSDateFormatter()
        timeFormatter.dateFormat = "hh:mm"
        //Can also set the default styles for date or time using .timeStyle or .dateStyle
        return timeFormatter.stringFromDate(self)
    }

    //NSDate to date string
    func getDate() -> String {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "dd, MMM"
        return dateFormatter.stringFromDate(self)
    }

    //NSDate to String
    func getString() -> String {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
        return dateFormatter.stringFromDate(self)
    }
}

So while execution actual code will look like follows

    var dateObjFromString = NSDate(dateString: cutDateTime)
    var dateString = dateObjFromString.getDate()
    var timeString = dateObjFromString.getTime()
    var stringFromDate = dateObjFromString.getString()

There are some defaults methods as well but I guess it might not work for the format you have given from documentation

    -dateFromString(_:)
    -stringFromDate(_:)
    -localizedStringFromDate(_ date: NSDate,
                     dateStyle dateStyle: NSDateFormatterStyle,
                     timeStyle timeStyle: NSDateFormatterStyle) -> String

From the man read:

#include <unistd.h>
ssize_t read(int fd, void *buf, size_t count);

Input parameters:

• int fd file descriptor is an integer and not a file pointer. The file descriptor for stdin is 0

• void *buf pointer to buffer to store characters read by the read function

• size_t count maximum number of characters to read

So you can read character by character with the following code:

char buf[1];

while(read(0, buf, sizeof(buf))>0) {
   // read() here read from stdin charachter by character
   // the buf[0] contains the character got by read()
   ....
}

My first post... UDF I managed quickly to compile. Usage: Select 3D range as normal and enclose is into quotation marks like below...

=CountIf3D("'StartSheet:EndSheet'!G16:G878";"Criteria")

Advisably sheets to be adjacent to avoid unanticipated results.

Public Function CountIf3D(SheetstoCount As String, CriteriaToUse As Variant)

     Dim sStarSheet As String, sEndSheet As String, sAddress As String
     Dim lColonPos As Long, lExclaPos As Long, cnt As Long

    lColonPos = InStr(SheetstoCount, ":") 'Finding ':' separating sheets
    lExclaPos = InStr(SheetstoCount, "!") 'Finding '!' separating address from the sheets

    sStarSheet = Mid(SheetstoCount, 2, lColonPos - 2) 'Getting first sheet's name
    sEndSheet = Mid(SheetstoCount, lColonPos + 1, lExclaPos - lColonPos - 2) 'Getting last sheet's name

    sAddress = Mid(SheetstoCount, lExclaPos + 1, Len(SheetstoCount) - lExclaPos) 'Getting address

        cnt = 0
   For i = Sheets(sStarSheet).Index To Sheets(sEndSheet).Index
        cnt = cnt + Application.CountIf(Sheets(i).Range(sAddress), CriteriaToUse)
   Next

   CountIf3D = cnt

End Function

In python3, there is a bytes() method that is in the same format as encode().

str1 = b'hello world'
str2 = bytes("hello world", encoding="UTF-8")
print(str1 == str2) # Returns True

I didn't read anything about this in the docs, but perhaps I wasn't looking in the right place. This way you can explicitly turn strings into byte streams and have it more readable than using encode and decode, and without having to prefex b in front of quotes.

Like this:

var root = document.getElementsByTagName( 'html' )[0]; // '0' to assign the first (and only `HTML` tag)

root.setAttribute( 'class', 'myCssClass' );

Or use this as your 'setter' line to preserve any previously applied classes: (thanks @ama2)

root.className += ' myCssClass';

Or, depending on the required browser support, you can use the classList.add() method:

root.classList.add('myCssClass');

https://developer.mozilla.org/en-US/docs/Web/API/Element/classList http://caniuse.com/#feat=classlist

UPDATE:

A more elegant solution for referencing the HTML element might be this:

var root = document.documentElement;
root.className += ' myCssClass';
// ... or:
//  root.classList.add('myCssClass');
//

I strongly recommend using Java generics to specify what type of object is in that List, ie. List<Car>. If you have Cars and Trucks you can use a common superclass/interface like this List<Vehicle>.

However, you can use Spring's ReflectionUtils to make fields accessible, even if they are private like the below runnable example:

List<Object> list = new ArrayList<Object>();

list.add("some value");
list.add(3);

for(Object obj : list)
{
    Class<?> clazz = obj.getClass();

    Field field = org.springframework.util.ReflectionUtils.findField(clazz, "value");
    org.springframework.util.ReflectionUtils.makeAccessible(field);

    System.out.println("value=" + field.get(obj));
}

Running this has an output of:

value=[C@1b67f74
value=3

Starting from C# 8, you simply can use Range Operator. It's the more efficient and better way to handle such cases.

string AnString = "Hello World!";
AnString = AnString[10..];

It will likely have been solved by now, but I ran accross this and figured to give my input

=COUNTIF(a2:a51;"*iPad*")

The important thing is that separating parameters in google docs is using a ; and not a ,

From the docs

Reduction operations A reduction operation (also called a fold) takes a sequence of input elements and combines them into a single summary result by repeated application of a combining operation, such as finding the sum or maximum of a set of numbers, or accumulating elements into a list. The streams classes have multiple forms of general reduction operations, called reduce() and collect(), as well as multiple specialized reduction forms such as sum(), max(), or count().

Of course, such operations can be readily implemented as simple sequential loops, as in:

int sum = 0;
for (int x : numbers) {
   sum += x;
}

However, there are good reasons to prefer a reduce operation over a mutative accumulation such as the above. Not only is a reduction "more abstract" -- it operates on the stream as a whole rather than individual elements -- but a properly constructed reduce operation is inherently parallelizable, so long as the function(s) used to process the elements are associative and stateless. For example, given a stream of numbers for which we want to find the sum, we can write:

int sum = numbers.stream().reduce(0, (x,y) -> x+y);

or:

int sum = numbers.stream().reduce(0, Integer::sum);

These reduction operations can run safely in parallel with almost no modification:

int sum = numbers.parallelStream().reduce(0, Integer::sum);

So, for a map you would use:

integers.values().stream().mapToInt(i -> i).reduce(0, (x,y) -> x+y);

Or:

integers.values().stream().reduce(0, Integer::sum);

For casting varchar fields/values to number format can be little hack used:

SELECT (`PROD_CODE` * 1) AS `PROD_CODE` FROM PRODUCT`

Had the same problem...im also new at javascript but i solved this with req.connection.remoteAddress; that gave me th IP address (but in ipv6 format ::ffff.192.168.0.101 ) and then .slice to remove the 7 first digits.

var ip = req.connection.remoteAddress;

if (ip.length < 15) 
{   
   ip = ip;
}
else
{
   var nyIP = ip.slice(7);
   ip = nyIP;
}

The problem is that if you try to write a <table> or a <tr> or <td> tag using JS every time you insert a new tag the browser will try to close it as it will think that there is an error on the code.

Instead of writing your table line by line, concatenate your table into a variable and insert it once created:

<script language="javascript" type="text/javascript">
<!--

var myArray    = new Array();
    myArray[0] = 1;
    myArray[1] = 2.218;
    myArray[2] = 33;
    myArray[3] = 114.94;
    myArray[4] = 5;
    myArray[5] = 33;
    myArray[6] = 114.980;
    myArray[7] = 5;

    var myTable= "<table><tr><td style='width: 100px; color: red;'>Col Head 1</td>";
    myTable+= "<td style='width: 100px; color: red; text-align: right;'>Col Head 2</td>";
    myTable+="<td style='width: 100px; color: red; text-align: right;'>Col Head 3</td></tr>";

    myTable+="<tr><td style='width: 100px;                   '>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td></tr>";

  for (var i=0; i<8; i++) {
    myTable+="<tr><td style='width: 100px;'>Number " + i + " is:</td>";
    myArray[i] = myArray[i].toFixed(3);
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td>";
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td></tr>";
  }  
   myTable+="</table>";

 document.write( myTable);

//-->
</script> 

If your code is in an external JS file, in HTML create an element with an ID where you want your table to appear:

<div id="tablePrint"> </div>

And in JS instead of document.write(myTable) use the following code:

document.getElementById('tablePrint').innerHTML = myTable;

The easiest way is to get the year from Calendar.

// year is stored as a static member
int year = Calendar.getInstance().get(Calendar.YEAR);

IE8/9 render the non-breaking hyphen mentioned in CanSpice's answer longer than a typical hyphen. It is the length of an en-dash instead of a typical hyphen. This display difference was a deal breaker for me.

As I could not use the CSS answer specified by Deb I instead opted to use no break tags.

<nobr>e-mail</nobr>

In addition I found a specific scenario that caused IE8/9 to break on a hyphen.

• A string contains words separated by non-breaking spaces -  
• Width is limited
• Contains a dash

IE renders it like this.

The following code reproduces the problem pictured above. I had to use a meta tag to force rendering to IE9 as IE10 has fixed the issue. No fiddle because it does not support meta tags.

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta http-equiv="X-UA-Compatible" content="IE=9" />
        <meta charset="utf-8"/>
        <style>
            body { padding: 20px; }
            div { width: 300px; border: 1px solid gray; }
        </style>
    </head>
    <body>
        <div>      
            <p>If&nbsp;there&nbsp;is&nbsp;a&nbsp;-&nbsp;and&nbsp;words&nbsp;are&nbsp;separated&nbsp;by&nbsp;the&nbsp;whitespace&nbsp;code&nbsp;&amp;nbsp;&nbsp;then&nbsp;IE&nbsp;will&nbsp;wrap&nbsp;on&nbsp;the&nbsp;dash.</p>
        </div>
    </body>
</html>

Using a ScaleGestureDetector

When learning a new concept I don't like using libraries or code dumps. I found a good description here and in the documentation of how to resize an image by pinching. This answer is a slightly modified summary. You will probably want to add more functionality later, but it will help you get started.

Layout

The ImageView just uses the app logo since it is already available. You can replace it with any image you like, though.

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

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher"
        android:layout_centerInParent="true"/>

</RelativeLayout>

Activity

We use a ScaleGestureDetector on the activity to listen to touch events. When a scale (ie, pinch) gesture is detected, then the scale factor is used to resize the ImageView.

public class MainActivity extends AppCompatActivity {

    private ScaleGestureDetector mScaleGestureDetector;
    private float mScaleFactor = 1.0f;
    private ImageView mImageView;

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

        // initialize the view and the gesture detector
        mImageView = findViewById(R.id.imageView);
        mScaleGestureDetector = new ScaleGestureDetector(this, new ScaleListener());
    }

    // this redirects all touch events in the activity to the gesture detector
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mScaleGestureDetector.onTouchEvent(event);
    }

    private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {

        // when a scale gesture is detected, use it to resize the image
        @Override
        public boolean onScale(ScaleGestureDetector scaleGestureDetector){
            mScaleFactor *= scaleGestureDetector.getScaleFactor();
            mImageView.setScaleX(mScaleFactor);
            mImageView.setScaleY(mScaleFactor);
            return true;
        }
    }
}

Notes

• Although the activity had the gesture detector in the example above, it could have also been set on the image view itself.

• You can limit the size of the scaling with something like

  mScaleFactor = Math.max(0.1f, Math.min(mScaleFactor, 5.0f));
  

• Thanks again to Pinch-to-zoom with multi-touch gestures In Android

• Documentation
• Use Ctrl + mouse drag to simulate a pinch gesture in the emulator.

Going on

You will probably want to do other things like panning and scaling to some focus point. You can develop these things yourself, but if you would like to use a pre-made custom view, copy TouchImageView.java into your project and use it like a normal ImageView. It worked well for me and I only ran into one bug. I plan to further edit the code to remove the warning and the parts that I don't need. You can do the same.

The following should work,Please Try this:

$effectiveDate = strtotime("+1 months", strtotime(date("y-m-d")));
echo $time = date("y/m/d", $effectiveDate);

in jquery we have to use selector($) to declare variables

var test=$("<%=ddl.ClientId%>");

here we can get the id of drop down to j query variable

Your path includes " at the beginning and at the end. Drop the quotes, and it'll be ok.

The \" at the beginning and end of what you see in VS Debugger is what tells us that the quotes are literally in the string.

function groupBy(array, groupBy){
        return array.reduce((acc,curr,index,array) => {
           var  idx = curr[groupBy]; 
              if(!acc[idx]){
                    acc[idx] = array.filter(item => item[groupBy] === idx)
              } 
            return  acc; 

        },{})
    }

// call
groupBy(items,'Step')

From the oracle documentation, the below query explains it better

INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;

You can read this link

Your query would be as follows

//just the concept    
    INSERT INTO quotedb
    (COLUMN_NAMES) //seperated by comma
    SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker

Note: Make sure the columns in insert and select are in right position as per your requirement

Hope this helps!

Profilers are definitely a good way to get numbers, but in my experience, perceived performance is all that matters to the user/client. For example, we had a project with an Ext accordion that expanded to show some data and then a few nested Ext grids. Everything was actually rendering pretty fast, no single operation took a long time, there was just a lot of information being rendered all at once, so it felt slow to the user.

We 'fixed' this, not by switching to a faster component, or optimizing some method, but by rendering the data first, then rendering the grids with a setTimeout. So, the information appeared first, then the grids would pop into place a second later. Overall, it took slightly more processing time to do it that way, but to the user, the perceived performance was improved.

These days, the Chrome profiler and other tools are universally available and easy to use, as are console.time(), console.profile(), and performance.now(). Chrome also gives you a timeline view which can show you what is killing your frame rate, where the user might be waiting, etc.

Finding documentation for all these tools is really easy, you don't need an SO answer for that. 7 years later, I'll still repeat the advice of my original answer and point out that you can have slow code run forever where a user won't notice it, and pretty fast code running where they do, and they will complain about the pretty fast code not being fast enough. Or that your request to your server API took 220ms. Or something else like that. The point remains that if you take a profiler out and go looking for work to do, you will find it, but it may not be the work your users need.

For spring boot version 2.X.X below configuration worked for me.

spring.datasource.url=jdbc:mysql://localhost:3306/rest
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto = update 

Old jdbc driver is deprecated. The new one is mentioned on above configuration. Please use the same and restart the project.

I think you are trying to configure your service in a similar way to the following config. There is more information here: Specify a Service with Two Endpoints Using Different Binding Values. Also, other than for development, it's probably not a good idea to have both HTTP & HTTPS endpoints to the same service. It kinda defeats the purpose of HTTPS. Hope this helps!

We can consider a telephone call In that Number is wsdl and exchange of information is soap.

WSDL is description how to connect with communication server.SOAP is have communication messages.

Of course:

curl http://example.com:11740
curl https://example.com:11740

Port 80 and 443 are just default port numbers.

Update: Now supported in most major browsers

document.querySelector("p").closest(".near.ancestor")

Note that this can match selectors, not just classes

https://developer.mozilla.org/en-US/docs/Web/API/Element.closest

For legacy browsers that do not support closest() but have matches() one can build selector-matching similar to @rvighne's class matching:

function findAncestor (el, sel) {
    while ((el = el.parentElement) && !((el.matches || el.matchesSelector).call(el,sel)));
    return el;
}

I was able to do this for the JDK14 binding by first requesting the SLF4J Logger instance and then setting the level on the binding -- you may try this for the Log4J binding.

private void setLevel(Class loggerClass, java.util.logging.Level level) {
  org.slf4j.LoggerFactory.getLogger(loggerClass);
  java.util.logging.Logger.getLogger(loggerClass.getName()).setLevel(level);
}

Noneof the answers worked for me, I was getting "'HttpRequestBase' does not contain a definition for 'Query'", but this did work:

HttpContext.Current.Request.QueryString["index"]

Use mouse_event or keybd_event. They say not to use them anymore but you don't have to find the window at all.

using System;
using System.Runtime.InteropServices;

public class SimulatePCControl

public static extern void keybd_event(uint bVk, uint bScan, uint dwFlags, uint dwExtraInfo);

private const int VK_LEFT = 0x25;

public static void LeftArrow()
{
    keybd_event(VK_LEFT, 0, 0, 0);
}

}

Virtual Key Codes are here for this one: http://www.kbdedit.com/manual/low_level_vk_list.html

Also for mouse:

using System.Runtime.InteropServices;
using UnityEngine;

public class SimulateMouseClick

public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);
//Mouse actions

private const int MOUSEEVENTF_LEFTUP = 0x04;
private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
private const int MOUSEEVENTF_RIGHTUP = 0x10;

public static void Click()

    //Call the imported function with the cursor's current position
    uint X = (uint)0;
    uint Y = (uint)0;
    mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
    Debug.LogError("SIMULATED A MOUSE CLICK JUST NOW...");

there is a command called dialog which uses the ncurses library. "Dialog is a program that will let you to present a variety of questions or display messages using dialog boxes from a shell script. These types of dialog boxes are implemented (though not all are necessarily compiled into dialog)"

see http://pwet.fr/man/linux/commandes/dialog

If using ES6, you could use a for loop to achieve this:

for (let i = 1; i < 10; i++) {
  setTimeout(function timer() {
    console.log("hello world");
  }, i * 3000);
}

It declares i for each iteration, meaning the timeout is what it was before + 1000. This way, what is passed to setTimeout is exactly what we want.

ECMAScript 6 sets can permit faster computing of the elements of one array that aren't in the other:

const myArray = ['a', 'b', 'c', 'd', 'e', 'f', 'g'];
const toRemove = new Set(['b', 'c', 'g']);

const difference = myArray.filter( x => !toRemove.has(x) );

console.log(difference); // ["a", "d", "e", "f"]

Since the lookup complexity for the V8 engine browsers use these days is O(1), the time complexity of the whole algorithm is O(n).

This is non-sql method. Instructions are given on the image itself. Select the server that you want to find the info about and then follow the steps.

I was getting the same issue with a different application,

I was using the The Enhanced Mitigation Experience Toolkit (EMET) from Microsoft and I found by disabling the EMET features on javaw.exe in my case as this was the faulting application, it enabled my application to run successfully. Make sure you don't have any similar software with security protections on memory.

If you look at the PHP constant PATH_SEPARATOR, you will see it being ":" for you.

If you break apart your string ".:/usr/share/pear:/usr/share/php" using that character, you will get 3 parts.

• . (this means the current directory your code is in)
• /usr/share/pear
• /usr/share/php

Any attempts to include()/require() things, will look in these directories, in this order.

It is showing you that in the error message to let you know where it could NOT find the file you were trying to require()

For your first require, if that is being included from your index.php, then you dont need the dir stuff, just do...

require_once ( 'db/config.php');

[id^=product]

^= indicates "starts with". Conversely, $= indicates "ends with".

The symbols are actually borrowed from Regex syntax, where ^ and $ mean "start of string" and "end of string" respectively.

See the specs for full information.

This is a MySQL-specific answer, not sure where else it works --

You can create an empty table having the same column definitions with:

CREATE TEMPORARY TABLE temp_foo LIKE foo;

And you can create a populated copy of an existing table with:

CREATE TEMPORARY TABLE temp_foo SELECT * FROM foo;

And the following works in postgres; unfortunately the different RDBMS's don't seem very consistent here:

CREATE TEMPORARY TABLE temp_foo AS SELECT * FROM foo;

I simplified your code to isolate the test for "%" being in the cell. Once you get that to work, you can add in the rest of your code.

Try this:

Option Explicit


Sub DoIHavePercentSymbol()
   Dim rng As Range

   Set rng = ActiveCell

   Do While rng.Value <> Empty
        If InStr(rng.Value, "%") = 0 Then
            MsgBox "I know nothing about percentages!"
            Set rng = rng.Offset(1)
            rng.Select
        Else
            MsgBox "I contain a % symbol!"
            Set rng = rng.Offset(1)
            rng.Select
        End If
   Loop

End Sub

InStr will return the number of times your search text appears in the string. I changed your if test to check for no matches first.

The message boxes and the .Selects are there simply for you to see what is happening while you are stepping through the code. Take them out once you get it working.

I had previously moved my mysql directory and forgot to change ALL references to the old location in \mysql\bin\my.ini.

change these three lines:

datadir = "/programs/xampp/mysql/data"
innodb_data_home_dir = "/programs/xampp/mysql/data"
innodb_log_group_home_dir = "/programs/xampp/mysql/data"

Change "/programs/xampp/mysql/data" to new location this one was commented but I changed it anyways

#innodb_log_arch_dir = "/programs/xampp/mysql/data"

Never forget that offset() function is giving your element's position to document. So when you need scroll your element relative to its parent you should use this;

    $('.a-parent-div').find('a').click(function(event){
        event.preventDefault();
        $('.scroll-div').animate({
     scrollTop: $( $.attr(this, 'href') ).position().top + $('.scroll-div').scrollTop()
     }, 500);       
  });

The key point is getting scrollTop of scroll-div and add it to scrollTop. If you won't do that position() function always gives you different position values.

Suppose you have a suite with 10 tests. 8 of the tests share the same setup/teardown code. The other 2 don't.

setup and teardown give you a nice way to refactor those 8 tests. Now what do you do with the other 2 tests? You'd move them to another testcase/suite. So using setup and teardown also helps give a natural way to break the tests into cases/suites

If you're running on Passenger, then the default is to run in production, in your apache conf:

<VirtualHost *:80>
  ServerName application_name.rails.local
  DocumentRoot "/Users/rails/application_name/public"
  RailsEnv production ## This is the default
</VirtualHost>

If you're just running a local server with mongrel or webrick, you can do:

./script/server -e production

or in bash:

RAILS_ENV=production ./script/server

actually overriding the RAILS_ENV constant in the enviornment.rb should probably be your last resort, as it's probably not going to stay set (see another answer I gave on that)

Variables (something) are not valid JSON, verify using http://jsonlint.com/

If you are using date-fns and if you dont want to install the Moment.js or the moment-precise-range-plugin. You can use the following date-fns function to get the same result as moment-precise-range-plugin

intervalToDuration({
  start: new Date(),
  end: new Date("24 Jun 2020")
})

This will give output in a JSON object like below

{
  "years": 0,
  "months": 0,
  "days": 0,
  "hours": 19,
  "minutes": 35,
  "seconds": 24
}

The best URL Regex that worked for me:

function valid_URL($url){
    return preg_match('%^(?:(?:https?|ftp)://)(?:\S+(?::\S*)?@|\d{1,3}(?:\.\d{1,3}){3}|(?:(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)(?:\.(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)*(?:\.[a-z\x{00a1}-\x{ffff}]{2,6}))(?::\d+)?(?:[^\s]*)?$%iu', $url);
}

Examples:

valid_URL('https://twitter.com'); // true
valid_URL('http://twitter.com');  // true
valid_URL('http://twitter.co');   // true
valid_URL('http://t.co');         // true
valid_URL('http://twitter.c');    // false
valid_URL('htt://twitter.com');   // false

valid_URL('http://example.com/?a=1&b=2&c=3'); // true
valid_URL('http://127.0.0.1');    // true
valid_URL('');                    // false
valid_URL(1);                     // false

Normal rounding will work with a small tweak:

Math.round(price * 10)/10

and if you want to keep a currency format, you can use the Number method .toFixed()

(Math.round(price * 10)/10).toFixed(2)

Though this will make it a String =)

I know this topic is old, but it ranks very well in Google. I found out that putting this in your header works well;

<meta Http-Equiv="Cache-Control" Content="no-cache">
<meta Http-Equiv="Pragma" Content="no-cache">
<meta Http-Equiv="Expires" Content="0">
<meta Http-Equiv="Pragma-directive: no-cache">
<meta Http-Equiv="Cache-directive: no-cache">

Finally I have found the solution by using the following code:

$('body').on('click', '#upload', function(e){
        e.preventDefault();
        var formData = new FormData($(this).parents('form')[0]);

        $.ajax({
            url: 'upload.php',
            type: 'POST',
            xhr: function() {
                var myXhr = $.ajaxSettings.xhr();
                return myXhr;
            },
            success: function (data) {
                alert("Data Uploaded: "+data);
            },
            data: formData,
            cache: false,
            contentType: false,
            processData: false
        });
        return false;
});

In case you closed multiple projects and trying to re-open all of them then in Windows->Show view-> Navigator

This solved the problem for me!

Without the need for an external div. Just apply it to your given text box.

box-sizing: border-box; 

With this property "The width and height properties (and min/max properties) includes content, padding and border, but not the margin"

See description of property at w3schools.

Hope this helps someone!

For CSS inline style, this worked best for me.

execute below

Python manage.py makemigrations

It will show missing package.

Install missing package and again run below command to make sure if nothing is missed.

Python manage.py makemigrations

It will resolve your issue.

The style property lets you specify values for CSS properties.

The CSS width property takes a length as its value.

Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.

e1.style.width = "400px";

I'm sorry to say that to the best of my knowledge a pure PHP upload progress bar, or even a PHP/Javascript upload progress bar is not possible because of how PHP works. Your best bet is to use some form of Flash uploader.

AFAIK This is because your script is not executed until all the superglobals are populated, which includes $_FILES. By the time your PHP script gets called, the file is fully uploaded.

EDIT: This is no longer true. It was in 2010.

Date userDob = new SimpleDateFormat("yyyy-MM-dd").parse(dob);
Date today = new Date();
long diff =  today.getTime() - userDob.getTime();
int numOfDays = (int) (diff / (1000 * 60 * 60 * 24));
int hours = (int) (diff / (1000 * 60 * 60));
int minutes = (int) (diff / (1000 * 60));
int seconds = (int) (diff / (1000));

Put the test in a function and you will be able to reuse it and you have better code readability.

Do NOT use the "On Error Resume Next" since it may conflict with other part of your code.

Sub DoesTheSheetExists()
    If SheetExist("SheetName") Then
        Debug.Print "The Sheet Exists"
    Else
        Debug.Print "The Sheet Does NOT Exists"
    End If
End Sub

Function SheetExist(strSheetName As String) As Boolean
    Dim i As Integer

    For i = 1 To Worksheets.Count
        If Worksheets(i).Name = strSheetName Then
            SheetExist = True
            Exit Function
        End If
    Next i
End Function

When you use jackson to map from string to your concrete class, especially if you work with generic type. then this issue may happen because of different class loader. i met it one time with below scenarior:

Project B depend on Library A

in Library A:

public class DocSearchResponse<T> {
 private T data;
}

it has service to query data from external source, and use jackson to convert to concrete class

public class ServiceA<T>{
  @Autowired
  private ObjectMapper mapper;
  @Autowired
  private ClientDocSearch searchClient;

  public DocSearchResponse<T> query(Criteria criteria){
      String resultInString = searchClient.search(criteria);
      return convertJson(resultInString)
  }
}

public DocSearchResponse<T> convertJson(String result){
     return mapper.readValue(result, new TypeReference<DocSearchResponse<T>>() {});
  }
}

in Project B:

public class Account{
 private String name;
 //come with other attributes
}

and i use ServiceA from library to make query and as well convert data

public class ServiceAImpl extends ServiceA<Account> {
    
}

and make use of that

public class MakingAccountService {
    @Autowired
    private ServiceA service;
    public void execute(Criteria criteria){
      
        DocSearchResponse<Account> result = service.query(criteria);
        Account acc = result.getData(); //  java.util.LinkedHashMap cannot be cast to com.testing.models.Account
    }
}

it happen because from classloader of LibraryA, jackson can not load Account class, then just override method convertJson in Project B to let jackson do its job

public class ServiceAImpl extends ServiceA<Account> {
        @Override
        public DocSearchResponse<T> convertJson(String result){
         return mapper.readValue(result, new TypeReference<DocSearchResponse<T>>() {});
      }
    }
 }

You provide credentials in a URLRequest instance, like this in Swift 3:

let username = "user"
let password = "pass"
let loginString = String(format: "%@:%@", username, password)
let loginData = loginString.data(using: String.Encoding.utf8)!
let base64LoginString = loginData.base64EncodedString()

// create the request
let url = URL(string: "http://www.example.com/")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

// fire off the request
// make sure your class conforms to NSURLConnectionDelegate
let urlConnection = NSURLConnection(request: request, delegate: self)

Or in an NSMutableURLRequest in Swift 2:

// set up the base64-encoded credentials
let username = "user"
let password = "pass"
let loginString = NSString(format: "%@:%@", username, password)
let loginData: NSData = loginString.dataUsingEncoding(NSUTF8StringEncoding)!
let base64LoginString = loginData.base64EncodedStringWithOptions([])

// create the request
let url = NSURL(string: "http://www.example.com/")
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

// fire off the request
// make sure your class conforms to NSURLConnectionDelegate
let urlConnection = NSURLConnection(request: request, delegate: self)

Try this:

Spinner popupSpinner = new Spinner(context, Spinner.MODE_DIALOG);

See this link for more details.

It's worth mentioning that the validation properties are different for forms and form elements (note that touched and untouched are for fields only):

Input fields have the following states:

$untouched The field has not been touched yet
$touched The field has been touched
$pristine The field has not been modified yet
$dirty The field has been modified
$invalid The field content is not valid
$valid The field content is valid

They are all properties of the input field, and are either true or false.

Forms have the following states:

$pristine No fields have been modified yet
$dirty One or more have been modified
$invalid The form content is not valid
$valid The form content is valid
$submitted The form is submitted

They are all properties of the form, and are either true or false.

I assume that since you're using an XML declaration, you're not worrying about IE or older browsers.

So you can use display:table-cell and display:table-row like so:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

    <title></title>
    <style type="text/css">
        .toolbar ul {
            display:table-row;
        }
        .toolbar ul li
        {
            display: table-cell;
            height: 100px;
            list-style-type: none;
            margin: 10px;
            vertical-align: middle;
        }
        .toolbar ul li a {
            display:table-cell;
            vertical-align: middle;
            height:100px;
            border: solid 1px black;
        }
        .toolbar ul li.button a {
            height:50px;
            border: solid 1px black;
        }
    </style>
</head>
<body>
    <div class="toolbar">
        <ul>
            <li><a href="#">first item<br />
                first item<br />
                first item</a></li>
            <li><a href="#">second item</a></li>
            <li><a href="#">last item</a></li>
            <li class="button"><a href="#">button<br />
                button</a></li>
        </ul>
    </div>

terrific answer from DuckPuncher, for Python3 make sure you install pdfminer2 and do:

import io

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage


def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = io.StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos = set()

    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages,
                                  password=password,
                                  caching=caching,
                                  check_extractable=True):
        interpreter.process_page(page)



    fp.close()
    device.close()
    text = retstr.getvalue()
    retstr.close()
    return text

If it says the API key is listed as a header, more than likely you need to set it in the headers option of your http request. Normally something like this :

headers: {'Authorization': '[your API key]'}

Here is an example from another Question

$http({method: 'GET', url: '[the-target-url]', headers: {
  'Authorization': '[your-api-key]'}
});

Edit : Just saw you wanted to store the response in a variable. In this case I would probably just use AJAX. Something like this :

$.ajax({ 
   type : "GET", 
   url : "[the-target-url]", 
   beforeSend: function(xhr){xhr.setRequestHeader('Authorization', '[your-api-key]');},
   success : function(result) { 
       //set your variable to the result 
   }, 
   error : function(result) { 
     //handle the error 
   } 
 }); 

I got this from this question and I'm at work so I can't test it at the moment but looks solid

Edit 2: Pretty sure you should be able to use this line :

headers: {'Authorization': '[your API key]'},

instead of the beforeSend line in the first edit. This may be simpler for you

(It would really have been nice if you'd mentioned which Color type you were interested in to start with...)

One simple way of doing this is to just build up a dictionary via reflection:

public static class Colors
{
    private static readonly Dictionary<string, Color> dictionary =
        typeof(Color).GetProperties(BindingFlags.Public | 
                                    BindingFlags.Static)
                     .Where(prop => prop.PropertyType == typeof(Color))
                     .ToDictionary(prop => prop.Name,
                                   prop => (Color) prop.GetValue(null, null)));

    public static Color FromName(string name)
    {
        // Adjust behaviour for lookup failure etc
        return dictionary[name];
    }
}

That will be relatively slow for the first lookup (while it uses reflection to find all the properties) but should be very quick after that.

If you want it to be case-insensitive, you can pass in something like StringComparer.OrdinalIgnoreCase as an extra argument in the ToDictionary call. You can easily add TryParse etc methods should you wish.

Of course, if you only need this in one place, don't bother with a separate class etc :)

The solution of creating a new HTML file with HTML (Web Forms) Designer worked for that file but not for other, individual HTML files that I wanted to edit.

I did find the Open With option in the Open File dialogue and was able to select the HTML (Web Forms) Editor there. Having clicked the "Set as Default" option in that window, VS then remembered to use that editor when I opened other HTML files.

Just as example from github, it works. https://github.com/eligrey/FileSaver.js

<script src="FileSaver.js"></script>
<script type="text/javascript">
    var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
    saveAs(blob, "hello world.txt");
</script>

create external table table_name( 
Year int, 
Month int,
column_name data_type ) 
row format delimited fields terminated by ',' 
location '/user/user_name/example_data' TBLPROPERTIES('serialization.null.format'='', 'skip.header.line.count'='1');

You are posting the data, so it should be $_POST. But 'name' is not the best name to use.

name = "name"

will only cause confusion IMO.

What you're wanting to do isn't possible. Take, for instance, whether or not the code below looks valid:

class Test(object):

    def _decorator(self, foo):
        foo()

    def bar(self):
        pass
    bar = self._decorator(bar)

It, of course, isn't valid since self isn't defined at that point. The same goes for Test as it won't be defined until the class itself is defined (which its in the process of). I'm showing you this code snippet because this is what your decorator snippet transforms into.

So, as you can see, accessing the instance in a decorator like that isn't really possible since decorators are applied during the definition of whatever function/method they are attached to and not during instantiation.

If you need class-level access, try this:

class Test(object):

    @classmethod
    def _decorator(cls, foo):
        foo()

    def bar(self):
        pass
Test.bar = Test._decorator(Test.bar)

C# is a little different in this respect with JavaScript. Because of the strict checks, you define the size of the array and you are supposed to know everything about the array such as its bounds, where the last item was put and what items are unused. You are supposed to copy all the elements of the array into a new, bigger one, if you want to resize it.

So, if you use a raw array, there's no other way other than to maintain the last empty, available index assign items to the array at this index, like you're already doing.

However, if you'd like to have the runtime maintain this information and completely abstract away the array, but still use an array underneath, then C# provides a class named ArrayList that provides this abstraction.

The ArrayList abstracts a loosely typed array of Objects. See the source here.

It takes care of all the issues like resizing the array, maintaining the last index that is available, etc. However, it abstracts / encapsulates this information from you. All you use is the ArrayList.

To push an item of any type into the underlying array at the end of the underlying array, call the Add method on the ArrayList like so:

/* you may or may not define a size using a constructor overload */
var arrayList = new ArrayList(); 

arrayList.Add("Foo");

EDIT: A note about type restriction

Like every programming language and runtime does, C# categorizes heap objects from those that will not go on the heap and will only stay on the function's argument stack. C# notes this distinction by the name Value types vs. Reference types. All things whose value goes on the stack are called Value types, and those that will go on the heap are called Reference types. This is loosely similar to JavaScript's distinction between objects and literals.

You can put anything into an ArrayList in C#, whether the thing is a value type or a reference type. This makes it closest to the JavaScript array in terms of typelessness, although neither of the three -- the JavaScript array, the JavaScript language and the C# ArrayList -- are actually type-less.

So, you could put a number literal, a string literal, an object of a class you made up, a boolean, a float, a double, a struct, just about anything you wanted into an ArrayList.

That is because the ArrayList internally maintains and stores all that you put into it, into an array of Objects, as you will have noted in my original answer and the linked source code.

And when you put something that isn't an object, C# creates a new object of type Object, stores the value of the thing you put into the ArrayList into this new Object type object. This process is called boxing and isn't very much unlike the JavaScript boxing mechanism.

For e.g. in JavaScript, while you could use a numeric literal to invoke a function on the Number object, you couldn't add something to the number literal's prototype.

// Valid javascript
var s = 4.toString();

// Invalid JavaScript code
4.prototype.square = () => 4 * 4;
var square = 4.square();

Just like JavaScript boxes the numeric literal 4 in the call to the toString method, C# boxes all things that are not objects into an Object type when putting them into an ArrayList.

var arrayList = new ArrayList();

arrayList.Add(4); // The value 4 is boxed into a `new Object()` first and then that new object is inserted as the last element in the `ArrayList`.

This involves a certain penalty, as it does in the case of JavaScript as well.

In C#, you can avoid this penalty as C# provides a strongly typed version of the ArrayList, known as the List<T>. So it follows that you cannot put anything into a List<T>; just T types.

However, I assume from your question's text that you already knew that C# had generic structures for strongly typed items. And your question was to have a JavaScript like data structure exhibiting the semantics of typelessness and elasticity, like the JavaScript Array object. In this case, the ArrayList comes closest.

It is also clear from your question that your interest was academic and not to use the structure in a production application.

So, I assume that for a production application, you would already know that a generic / strongly typed data structure (List<T> for example) is better performing than its non-typed one (ArrayList for example).

Git has a configuration setting that tells it whether to be case sensitive or insensitive: core.ignorecase. To tell Git to be case-senstive, simply set this setting to false. (Be careful if you have already pushed the files, then you should first move them given the other answers).

git config core.ignorecase false

From the git config documentation:

core.ignorecase

If true, this option enables various workarounds to enable git to work better on filesystems that are not case sensitive, like FAT. For example, if a directory listing finds makefile when git expects Makefile, git will assume it is really the same file, and continue to remember it as Makefile.

The default is false, except git-clone(1) or git-init(1) will probe and set core.ignorecase true if appropriate when the repository is created.

Case-insensitive file-systems

The two most popular operating systems that have case-insensitive file systems that I know of are

• Windows
• OS X

Notice how most of these can only be used WITHOUT a DOCTYPE. I'm looking for the same answer, but I have a DOCTYPE. There is one way to do it with a DOCTYPE however, although it doesn't apply to the style of my site, but it will work on the type of page you want to create:

div#full-size{
    position: absolute;
    top:0;
    bottom:0;
    right:0;
    left:0;
    overflow:hidden;

Now, this was mentioned earlier but I just wanted to clarify that this is normally used with a DOCTYPE, height:100%; only works without a DOCTYPE

Remove apache from Control Panel and delete the apache folder from Program Files and restart the machine, then install apache again. This will solve the problem; if not do the following: Install IIS if not installed, then start IIS and stop it ... Using services start apache service... enjoy apache.

The python manual provides the following:

import termios, fcntl, sys, os
fd = sys.stdin.fileno()

oldterm = termios.tcgetattr(fd)
newattr = termios.tcgetattr(fd)
newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
termios.tcsetattr(fd, termios.TCSANOW, newattr)

oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

try:
    while 1:
        try:
            c = sys.stdin.read(1)
            print "Got character", repr(c)
        except IOError: pass
finally:
    termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
    fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

which can be rolled into your use case.

The F5 Refresh has the semantic of "please reload the current HTML AND its direct dependancies". Hence you should expect to see any imgs, css and js resource directly referenced by the HTML also being refetched. Of course a 304 is an acceptable response to this but F5 refresh implies that the browser will make the request rather than rely on fresh cache content.

Instead try simply navigating somewhere else and then navigating back.

You can force the refresh, past a 304, by holding ctrl while pressing f5 in most browsers.

Whilst the most upvoted answer is correct but it lacks usage of multi-core processing. In my case, having 12 cores I use PLink:

Parallel.ForEach(
    File.ReadLines(filename), //returns IEumberable<string>: lazy-loading
    new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount },
    (line, state, index) =>
    {
        //process line value
    }
);

Worth mentioning, I got that as an interview question asking return Top 10 most occurrences:

var result = new ConcurrentDictionary<string, int>(StringComparer.InvariantCultureIgnoreCase);
Parallel.ForEach(
    File.ReadLines(filename),
    new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount },
    (line, state, index) =>
    {
        result.AddOrUpdate(line, 1, (key, val) => val + 1);        
    }
);

return result
    .OrderByDescending(x => x.Value)
    .Take(10)
    .Select(x => x.Value);

Your Fragment can subclass ListFragment.
And onCreateView() from ListFragment will return a ListView you can then populate.

First of all, check out my post on retained Fragments. It might help.

Now to answer your questions:

Does the fragment also retain its view state, or will this be recreated on configuration change - what exactly is "retained"?

Yes, the Fragment's state will be retained across the configuration change. Specifically, "retained" means that the fragment will not be destroyed on configuration changes. That is, the Fragment will be retained even if the configuration change causes the underlying Activity to be destroyed.

Will the fragment be destroyed when the user leaves the activity?

Just like Activitys, Fragments may be destroyed by the system when memory resources are low. Whether you have your fragments retain their instance state across configuration changes will have no effect on whether or not the system will destroy the Fragments once you leave the Activity. If you leave the Activity (i.e. by pressing the home button), the Fragments may or may not be destroyed. If you leave the Activity by pressing the back button (thus, calling finish() and effectively destroying the Activity), all of the Activitys attached Fragments will also be destroyed.

Why doesn't it work with fragments on the back stack?

There are probably multiple reasons why it's not supported, but the most obvious reason to me is that the Activity holds a reference to the FragmentManager, and the FragmentManager manages the backstack. That is, no matter if you choose to retain your Fragments or not, the Activity (and thus the FragmentManager's backstack) will be destroyed on a configuration change. Another reason why it might not work is because things might get tricky if both retained fragments and non-retained fragments were allowed to exist on the same backstack.

Which are the use cases where it makes sense to use this method?

Retained fragments can be quite useful for propagating state information — especially thread management — across activity instances. For example, a fragment can serve as a host for an instance of Thread or AsyncTask, managing its operation. See my blog post on this topic for more information.

In general, I would treat it similarly to using onConfigurationChanged with an Activity... don't use it as a bandaid just because you are too lazy to implement/handle an orientation change correctly. Only use it when you need to.

SOAP 1.1 uses namespace http://schemas.xmlsoap.org/wsdl/soap/

SOAP 1.2 uses namespace http://schemas.xmlsoap.org/wsdl/soap12/

The wsdl is able to define operations under soap 1.1 and soap 1.2 at the same time in the same wsdl. Thats useful if you need to evolve your wsdl to support new functionality that requires soap 1.2 (eg. MTOM), in this case you dont need to create a new service but just evolve the original one.

You can do a form.serializeArray(), then add name-value pairs before posting:

var form = $(this).closest('form');

form = form.serializeArray();

form = form.concat([
    {name: "customer_id", value: window.username},
    {name: "post_action", value: "Update Information"}
]);

$.post('/change-user-details', form, function(d) {
    if (d.error) {
        alert("There was a problem updating your user details")
    } 
});

To reliably filter IE8 and older, checking global objects can be used:

if (document.all && !document.addEventListener) {
    alert('IE8 or lower');
}

It's really interesting case. Actually in your setup the following statement is true:

binary_crossentropy = len(class_id_index) * categorical_crossentropy

This means that up to a constant multiplication factor your losses are equivalent. The weird behaviour that you are observing during a training phase might be an example of a following phenomenon:

1. At the beginning the most frequent class is dominating the loss - so network is learning to predict mostly this class for every example.
2. After it learnt the most frequent pattern it starts discriminating among less frequent classes. But when you are using adam - the learning rate has a much smaller value than it had at the beginning of training (it's because of the nature of this optimizer). It makes training slower and prevents your network from e.g. leaving a poor local minimum less possible.

That's why this constant factor might help in case of binary_crossentropy. After many epochs - the learning rate value is greater than in categorical_crossentropy case. I usually restart training (and learning phase) a few times when I notice such behaviour or/and adjusting a class weights using the following pattern:

class_weight = 1 / class_frequency

This makes loss from a less frequent classes balancing the influence of a dominant class loss at the beginning of a training and in a further part of an optimization process.

EDIT:

Actually - I checked that even though in case of maths:

binary_crossentropy = len(class_id_index) * categorical_crossentropy

should hold - in case of keras it's not true, because keras is automatically normalizing all outputs to sum up to 1. This is the actual reason behind this weird behaviour as in case of multiclassification such normalization harms a training.

If you want to add onClick() to the child view of items, for example, a button in item, I found that you can do it easily in onCreateViewHolder() of your own RecyclerView.Adapter just like this:

        @Override
        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View v = LayoutInflater
                    .from(parent.getContext())
                    .inflate(R.layout.cell, null);

            Button btn = (Button) v.findViewById(R.id.btn);
            btn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //do it
                }
            });

            return new MyViewHolder(v);
        }

i don't know whether it's a good way, but it works well. If anyone has a better idea, very glad to tell me and correct my answer! :)

This error occurs when the linker can't find WinMain function, so it is probably missing. In your case, you are probably missing main too.

Consider the following Windows API-level program:

#define NOMINMAX
#include <windows.h>

int main()
{
    MessageBox( 0, "Blah blah...", "My Windows app!", MB_SETFOREGROUND );
}

Now let's build it using GNU toolchain (i.e. g++), no special options. Here gnuc is just a batch file that I use for that. It only supplies options to make g++ more standard:

C:\test> gnuc x.cpp

C:\test> objdump -x a.exe | findstr /i "^subsystem"
Subsystem               00000003        (Windows CUI)

C:\test> _

This means that the linker by default produced a console subsystem executable. The subsystem value in the file header tells Windows what services the program requires. In this case, with console system, that the program requires a console window.

This also causes the command interpreter to wait for the program to complete.

Now let's build it with GUI subsystem, which just means that the program does not require a console window:

C:\test> gnuc x.cpp -mwindows

C:\test> objdump -x a.exe | findstr /i "^subsystem"
Subsystem               00000002        (Windows GUI)

C:\test> _

Hopefully that's OK so far, although the -mwindows flag is just semi-documented.

Building without that semi-documented flag one would have to more specifically tell the linker which subsystem value one desires, and some Windows API import libraries will then in general have to be specified explicitly:

C:\test> gnuc x.cpp -Wl,-subsystem,windows

C:\test> objdump -x a.exe | findstr /i "^subsystem"
Subsystem               00000002        (Windows GUI)

C:\test> _

That worked fine, with the GNU toolchain.

But what about the Microsoft toolchain, i.e. Visual C++?

Well, building as a console subsystem executable works fine:

C:\test> msvc x.cpp user32.lib
x.cpp

C:\test> dumpbin /headers x.exe | find /i "subsystem" | find /i "Windows"
               3 subsystem (Windows CUI)

C:\test> _

However, with Microsoft's toolchain building as GUI subsystem does not work by default:

C:\test> msvc x.cpp user32.lib /link /subsystem:windows
x.cpp
LIBCMT.lib(wincrt0.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartu
p
x.exe : fatal error LNK1120: 1 unresolved externals

C:\test> _

Technically this is because Microsoft’s linker is non-standard by default for GUI subsystem. By default, when the subsystem is GUI, then Microsoft's linker uses a runtime library entry point, the function where the machine code execution starts, called winMainCRTStartup, that calls Microsoft's non-standard WinMain instead of standard main.

No big deal to fix that, though.

All you have to do is to tell Microsoft's linker which entry point to use, namely mainCRTStartup, which calls standard main:

C:\test> msvc x.cpp user32.lib /link /subsystem:windows /entry:mainCRTStartup
x.cpp

C:\test> dumpbin /headers x.exe | find /i "subsystem" | find /i "Windows"
               2 subsystem (Windows GUI)

C:\test> _

No problem, but very tedious. And so arcane and hidden that most Windows programmers, who mostly only use Microsoft’s non-standard-by-default tools, do not even know about it, and mistakenly think that a Windows GUI subsystem program “must” have non-standard WinMain instead of standard main. In passing, with C++0x Microsoft will have a problem with this, since the compiler must then advertize whether it's free-standing or hosted (when hosted it must support standard main).

Anyway, that's the reason why g++ can complain about WinMain missing: it's a silly non-standard startup function that Microsoft's tools require by default for GUI subsystem programs.

But as you can see above, g++ has no problem with standard main even for a GUI subsystem program.

So what could be the problem?

Well, you are probably missing a main. And you probably have no (proper) WinMain either! And then g++, after having searched for main (no such), and for Microsoft's non-standard WinMain (no such), reports that the latter is missing.

Testing with an empty source:

The easiest way is to use the create Manager method, which creates and saves the object in a single step.

Often this question is asked in the context of Ron de Bruin's RangeToHTML function, which creates an HTML PublishObject from an Excel.Range, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody. In doing so, this removes the default signature (the RangeToHTML function has a helper function GetBoiler which attempts to insert the default signature).

Unfortunately, the poorly-documented Application.CommandBars method is not available via Outlook:

wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"

It will raise a runtime 6158:

But we can still leverage the Word.Document which is accessible via the MailItem.GetInspector method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).

Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed

With OutMail
    .To = "[email protected]"
    .BCC = ""
    .Subject = "Subject"
    .Display
    Dim wdDoc As Object     '## Word.Document
    Dim wdRange As Object   '## Word.Range
    Set wdDoc = OutMail.GetInspector.WordEditor
    Set wdRange = wdDoc.Range(0, 0)
    wdRange.InsertAfter vbCrLf & vbCrLf
    'Copy the range in-place
    rng.Copy
    wdRange.Paste
End With

Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:

If you leave it blank the framework will try to autodetect it since version 2.0.0.

You can increase security in authentication process by using JWT (JSON Web Tokens) and SSL/HTTPS.

The Basic Auth / Session ID can be stolen via:

• MITM attack (Man-In-The-Middle) - without SSL/HTTPS
• An intruder gaining access to a user's computer
• XSS

By using JWT you're encrypting the user's authentication details and storing in the client, and sending it along with every request to the API, where the server/API validates the token. It can't be decrypted/read without the private key (which the server/API stores secretly) Read update.

The new (more secure) flow would be:

Login

• User logs in and sends login credentials to API (over SSL/HTTPS)
• API receives login credentials
• If valid:
  • Register a new session in the database Read update
  • Encrypt User ID, Session ID, IP address, timestamp, etc. in a JWT with a private key.
• API sends the JWT token back to the client (over SSL/HTTPS)
• Client receives the JWT token and stores in localStorage/cookie

Every request to API

• User sends a HTTP request to API (over SSL/HTTPS) with the stored JWT token in the HTTP header
• API reads HTTP header and decrypts JWT token with its private key
• API validates the JWT token, matches the IP address from the HTTP request with the one in the JWT token and checks if session has expired
• If valid:
  • Return response with requested content
• If invalid:
  • Throw exception (403 / 401)
  • Flag intrusion in the system
  • Send a warning email to the user.

Updated 30.07.15:

JWT payload/claims can actually be read without the private key (secret) and it's not secure to store it in localStorage. I'm sorry about these false statements. However they seem to be working on a JWE standard (JSON Web Encryption).

I implemented this by storing claims (userID, exp) in a JWT, signed it with a private key (secret) the API/backend only knows about and stored it as a secure HttpOnly cookie on the client. That way it cannot be read via XSS and cannot be manipulated, otherwise the JWT fails signature verification. Also by using a secure HttpOnly cookie, you're making sure that the cookie is sent only via HTTP requests (not accessible to script) and only sent via secure connection (HTTPS).

Updated 17.07.16:

JWTs are by nature stateless. That means they invalidate/expire themselves. By adding the SessionID in the token's claims you're making it stateful, because its validity doesn't now only depend on signature verification and expiry date, it also depends on the session state on the server. However the upside is you can invalidate tokens/sessions easily, which you couldn't before with stateless JWTs.

I was able to get this to work thanks to this post utilizing VisualWGet. It worked great for me. The important part seems to be to check the -recursive flag (see image).

Also found that the -no-parent flag is important, othewise it will try to download everything.

As of PHP 7.x, you can use the following:

$aDate = new \DateTime('@'.(time()));
$bDate = new \DateTime('@'.(time() - 3600));

$aDate <=> $bDate; // => 1, `$aDate` is newer than `$bDate`

declare @d real
set @d=1.0;
select @d*40000*(192+2)*20000+150000

When you boil down to it, it's just a fancy overly-complicated proxy, but maybe Catch-All Proxies could do it?

var o = {
    a: 'a',
    b: 'b',
    func: function() { return 'func'; }
};

var proxy = Proxy.create(handlerMaker(o), o);

(function(x){
    var obj = x;
    console.log(x.a);
    console.log(x.b);
    obj.foo = 'foo';
    obj.bar = 'bar';
})(proxy);

console.log(o.foo);

function handlerMaker(obj) {
  return {
   getOwnPropertyDescriptor: function(name) {
     var desc = Object.getOwnPropertyDescriptor(obj, name);
     // a trapping proxy's properties must always be configurable
     if (desc !== undefined) { desc.configurable = true; }
     return desc;
   },
   getPropertyDescriptor:  function(name) {
     var desc = Object.getOwnPropertyDescriptor(obj, name); // not in ES5
     // a trapping proxy's properties must always be configurable
     if (desc !== undefined) { desc.configurable = true; }
     return desc;
   },
   getOwnPropertyNames: function() {
     return Object.getOwnPropertyNames(obj);
   },
   getPropertyNames: function() {
     return Object.getPropertyNames(obj);                // not in ES5
   },
   defineProperty: function(name, desc) {

   },
   delete:       function(name) { return delete obj[name]; },   
   fix:          function() {}
  };
}

I had the same problem and solved it by updating the Android SDK Build-Tools. Open the SDK manager in Android studio (double shift and type SDK manager). Then on the second tab (SDK Tools) update the Android SDK Build-Tools and the error message should go away.

Do not use list as variable name. You can take a look at the following code too:

clist = ['element1\t0238.94', 'element2\t2.3904', 'element3\t0139847', 'element5']
clist = [x[:x.index('\t')] if '\t' in x else x for x in clist]

Or in-place editing:

for i,x in enumerate(clist):
    if '\t' in x:
        clist[i] = x[:x.index('\t')]

The issue isn't actually a syntax error, the Hive ParseException is just caused by a reserved keyword in Hive (in this case, end).

The solution: use backticks around the offending column name:

CREATE EXTERNAL TABLE moveProjects (cid string, `end` string, category string)
STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler'
TBLPROPERTIES ("dynamodb.table.name" = "Projects",
    "dynamodb.column.mapping" = "cid:cid,end:end,category:category");

With the added backticks around end, the query works as expected.

Reserved words in Amazon Hive (as of February 2013):

IF, HAVING, WHERE, SELECT, UNIQUEJOIN, JOIN, ON, TRANSFORM, MAP, REDUCE, TABLESAMPLE, CAST, FUNCTION, EXTENDED, CASE, WHEN, THEN, ELSE, END, DATABASE, CROSS

I ran into this same issue trying to install the dbf package in Python 2.7. The problem is that the enum package wasn't added to Python until version 3.4.

It has been backported to versions 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4, you just need the package from here: https://pypi.python.org/pypi/enum34#downloads

edit: with an example of marking an arbitrary subset of points, as requested in the comments:

import numpy as np
import matplotlib.pyplot as plt

xs = np.linspace(-np.pi, np.pi, 30)
ys = np.sin(xs)
markers_on = [12, 17, 18, 19]
plt.plot(xs, ys, '-gD', markevery=markers_on)
plt.show()

This last example using the markevery kwarg is possible in since 1.4+, due to the merge of this feature branch. If you are stuck on an older version of matplotlib, you can still achieve the result by overlaying a scatterplot on the line plot. See the edit history for more details.

    return 1; // or some valid int
}

I've been using DevStudio for far too many years now and it always amazes me just how many programmers don't know about the memory analysis tools that are available in the debug run time libraries. Here's a few links to get started with:

Tracking Heap Allocation Requests - specifically the section on Unique Allocation Request Numbers

_CrtSetDbgFlag

_CrtSetBreakAlloc

Of course, if you're not using DevStudio then this won't be particularly helpful.

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

You can plot the means without resorting to external calculations and additional tables using stat_summary(...). In fact, stat_summary(...) was designed for exactly what you are doing.

library(ggplot2)
library(reshape2)            # for melt(...)
gg <- melt(df,id="gender")   # df is your original table
ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  scale_color_discrete("Gender")
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey80",position=position_dodge(1), width=.2)

To add "error bars" you cna also use stat_summary(...) (here, I'm using the min and max value rather than sd because you have so little data).

ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey40",position=position_dodge(1), width=.2) +
  scale_fill_discrete("Gender")

For example if I had an application source code structure that looked like this:

• C:\b2b\com\steve\util\
• C:\b2b\com\steve\app\
• C:\b2b\com\steve\gui\

Then I would do:

javadoc -d "C:\docs" -sourcepath "C:\b2b" -subpackages com

And that should create javadocs for source code of the com package, and all subpackages (recursively), found inside the "C:\b2b" directory.

I'm late, but:

BufferReader.java:

public BufferedReader(Reader in) {
  this(in, defaultCharBufferSize);
}

(...)

public void close() throws IOException {
    synchronized (lock) {
        if (in == null)
            return;
        try {
            in.close();
        } finally {
            in = null;
            cb = null;
        }
    }
}

You can use this working script:

/**
* @param {range} countRange Range to be evaluated
* @param {range} colorRef Cell with background color to be searched for in countRange
* @return {number}
* @customfunction
*/

function countColoredCells(countRange,colorRef) {
  var activeRange = SpreadsheetApp.getActiveRange();
  var activeSheet = activeRange.getSheet();
  var formula = activeRange.getFormula();

  var rangeA1Notation = formula.match(/\((.*)\,/).pop();
  var range = activeSheet.getRange(rangeA1Notation);
  var bg = range.getBackgrounds();
  var values = range.getValues();

  var colorCellA1Notation = formula.match(/\,(.*)\)/).pop();
  var colorCell = activeSheet.getRange(colorCellA1Notation);
  var color = colorCell.getBackground();

  var count = 0;

  for(var i=0;i<bg.length;i++)
    for(var j=0;j<bg[0].length;j++)
      if( bg[i][j] == color )
        count=count+1;
  return count;
};

Then call this function in your google sheets:

=countColoredCells(D5:D123,Z11)

Ordinarily, floats aren't counted in the layout of their parents.

To prevent that, add overflow: hidden to the parent.

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

It should be like that

public static void main(String[] args) {
        EchoServer0 e = new EchoServer0();
        // TODO Auto-generated method stub
        e.listen();
}

Your variable of type Object truly doesn't have such a method, but the type EchoServer0 you define above certainly has.

For EditText in image above, You have to create two xml files in res-->drawable folder. First will be "bg_edittext_focused.xml" paste the lines of code in it

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <solid android:color="#FFFFFF" />
        <stroke
            android:width="2dip"
            android:color="#F6F6F6" />
        <corners android:radius="2dip" />
        <padding
            android:bottom="7dip"
            android:left="7dip"
            android:right="7dip"
            android:top="7dip" />
    </shape>

Second file will be "bg_edittext_normal.xml" paste the lines of code in it

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <solid android:color="#F6F6F6" />
        <stroke
            android:width="2dip"
            android:color="#F6F6F6" />
        <corners android:radius="2dip" />
        <padding
            android:bottom="7dip"
            android:left="7dip"
            android:right="7dip"
            android:top="7dip" />
    </shape>

In res-->drawable folder create another xml file with name "bg_edittext.xml" that will call above mentioned code. paste the following lines of code below in bg_edittext.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/bg_edittext_focused" android:state_focused="true"/>
    <item android:drawable="@drawable/bg_edittext_normal"/>
</selector>

Finally in res-->layout-->example.xml file in your case wherever you created your editText you'll call bg_edittext.xml as background

   <EditText
    :::::
    :::::  
    android:background="@drawable/bg_edittext"
    :::::
    :::::
    />

Using Vue 1.x, use the special variable $index like so:

<li v-for="catalog in catalogs">this index : {{$index + 1}}</li>

alternatively, you can specify an alias as a first argument for v-for directive like so:

<li v-for="(itemObjKey, catalog) in catalogs">
    this index : {{itemObjKey + 1}}
</li>

See : Vue 1.x guide

Using Vue 2.x, v-for provides a second optional argument referencing the index of the current item, you can add 1 to it in your mustache template as seen before:

<li v-for="(catalog, itemObjKey) in catalogs">
    this index : {{itemObjKey + 1}}
</li>

See: Vue 2.x guide

Eliminating the parentheses in the v-for syntax also works fine hence:

<li v-for="catalog, itemObjKey in catalogs">
    this index : {{itemObjKey + 1}}
</li>

Hope that helps.

Greedy means your expression will match as large a group as possible, lazy means it will match the smallest group possible. For this string:

abcdefghijklmc

and this expression:

a.*c

A greedy match will match the whole string, and a lazy match will match just the first abc.

TL;DR

mysql_real_escape_string() will provide no protection whatsoever (and could furthermore munge your data) if:

• MySQL's NO_BACKSLASH_ESCAPES SQL mode is enabled (which it might be, unless you explicitly select another SQL mode every time you connect); and

• your SQL string literals are quoted using double-quote " characters.

This was filed as bug #72458 and has been fixed in MySQL v5.7.6 (see the section headed "The Saving Grace", below).

This is another, (perhaps less?) obscure EDGE CASE!!!

In homage to @ircmaxell's excellent answer (really, this is supposed to be flattery and not plagiarism!), I will adopt his format:

The Attack

Starting off with a demonstration...

mysql_query('SET SQL_MODE="NO_BACKSLASH_ESCAPES"'); // could already be set
$var = mysql_real_escape_string('" OR 1=1 -- ');
mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');

This will return all records from the test table. A dissection:

1. Selecting an SQL Mode

   mysql_query('SET SQL_MODE="NO_BACKSLASH_ESCAPES"');
   

   As documented under String Literals:

   There are several ways to include quote characters within a string:

   • A “'” inside a string quoted with “'” may be written as “''”.

   • A “"” inside a string quoted with “"” may be written as “""”.

   • Precede the quote character by an escape character (“\”).

   • A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a string quoted with “'” needs no special treatment.

   If the server's SQL mode includes NO_BACKSLASH_ESCAPES, then the third of these options—which is the usual approach adopted by mysql_real_escape_string()—is not available: one of the first two options must be used instead. Note that the effect of the fourth bullet is that one must necessarily know the character that will be used to quote the literal in order to avoid munging one's data.

2. The Payload

   " OR 1=1 -- 
   

   The payload initiates this injection quite literally with the " character. No particular encoding. No special characters. No weird bytes.

3. mysql_real_escape_string()

   $var = mysql_real_escape_string('" OR 1=1 -- ');
   

   Fortunately, mysql_real_escape_string() does check the SQL mode and adjust its behaviour accordingly. See libmysql.c:

   ulong STDCALL
   mysql_real_escape_string(MYSQL *mysql, char *to,const char *from,
                ulong length)
   {
     if (mysql->server_status & SERVER_STATUS_NO_BACKSLASH_ESCAPES)
       return escape_quotes_for_mysql(mysql->charset, to, 0, from, length);
     return escape_string_for_mysql(mysql->charset, to, 0, from, length);
   }
   

   Thus a different underlying function, escape_quotes_for_mysql(), is invoked if the NO_BACKSLASH_ESCAPES SQL mode is in use. As mentioned above, such a function needs to know which character will be used to quote the literal in order to repeat it without causing the other quotation character from being repeated literally.

   However, this function arbitrarily assumes that the string will be quoted using the single-quote ' character. See charset.c:

   /*
     Escape apostrophes by doubling them up
   
   // [ deletia 839-845 ]
   
     DESCRIPTION
       This escapes the contents of a string by doubling up any apostrophes that
       it contains. This is used when the NO_BACKSLASH_ESCAPES SQL_MODE is in
       effect on the server.
   
   // [ deletia 852-858 ]
   */
   
   size_t escape_quotes_for_mysql(CHARSET_INFO *charset_info,
                                  char *to, size_t to_length,
                                  const char *from, size_t length)
   {
   // [ deletia 865-892 ]
   
       if (*from == '\'')
       {
         if (to + 2 > to_end)
         {
           overflow= TRUE;
           break;
         }
         *to++= '\'';
         *to++= '\'';
       }
   

   So, it leaves double-quote " characters untouched (and doubles all single-quote ' characters) irrespective of the actual character that is used to quote the literal! In our case $var remains exactly the same as the argument that was provided to mysql_real_escape_string()—it's as though no escaping has taken place at all.

4. The Query

   mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');
   

   Something of a formality, the rendered query is:

   SELECT * FROM test WHERE name = "" OR 1=1 -- " LIMIT 1
   

As my learned friend put it: congratulations, you just successfully attacked a program using mysql_real_escape_string()...

The Bad

mysql_set_charset() cannot help, as this has nothing to do with character sets; nor can mysqli::real_escape_string(), since that's just a different wrapper around this same function.

The problem, if not already obvious, is that the call to mysql_real_escape_string() cannot know with which character the literal will be quoted, as that's left to the developer to decide at a later time. So, in NO_BACKSLASH_ESCAPES mode, there is literally no way that this function can safely escape every input for use with arbitrary quoting (at least, not without doubling characters that do not require doubling and thus munging your data).

The Ugly

It gets worse. NO_BACKSLASH_ESCAPES may not be all that uncommon in the wild owing to the necessity of its use for compatibility with standard SQL (e.g. see section 5.3 of the SQL-92 specification, namely the <quote symbol> ::= <quote><quote> grammar production and lack of any special meaning given to backslash). Furthermore, its use was explicitly recommended as a workaround to the (long since fixed) bug that ircmaxell's post describes. Who knows, some DBAs might even configure it to be on by default as means of discouraging use of incorrect escaping methods like addslashes().

Also, the SQL mode of a new connection is set by the server according to its configuration (which a SUPER user can change at any time); thus, to be certain of the server's behaviour, you must always explicitly specify your desired mode after connecting.

The Saving Grace

So long as you always explicitly set the SQL mode not to include NO_BACKSLASH_ESCAPES, or quote MySQL string literals using the single-quote character, this bug cannot rear its ugly head: respectively escape_quotes_for_mysql() will not be used, or its assumption about which quote characters require repeating will be correct.

For this reason, I recommend that anyone using NO_BACKSLASH_ESCAPES also enables ANSI_QUOTES mode, as it will force habitual use of single-quoted string literals. Note that this does not prevent SQL injection in the event that double-quoted literals happen to be used—it merely reduces the likelihood of that happening (because normal, non-malicious queries would fail).

In PDO, both its equivalent function PDO::quote() and its prepared statement emulator call upon mysql_handle_quoter()—which does exactly this: it ensures that the escaped literal is quoted in single-quotes, so you can be certain that PDO is always immune from this bug.

As of MySQL v5.7.6, this bug has been fixed. See change log:

Functionality Added or Changed

• Incompatible Change: A new C API function, mysql_real_escape_string_quote(), has been implemented as a replacement for mysql_real_escape_string() because the latter function can fail to properly encode characters when the NO_BACKSLASH_ESCAPES SQL mode is enabled. In this case, mysql_real_escape_string() cannot escape quote characters except by doubling them, and to do this properly, it must know more information about the quoting context than is available. mysql_real_escape_string_quote() takes an extra argument for specifying the quoting context. For usage details, see mysql_real_escape_string_quote().

   Note

  Applications should be modified to use mysql_real_escape_string_quote(), instead of mysql_real_escape_string(), which now fails and produces an CR_INSECURE_API_ERR error if NO_BACKSLASH_ESCAPES is enabled.

  References: See also Bug #19211994.

Safe Examples

Taken together with the bug explained by ircmaxell, the following examples are entirely safe (assuming that one is either using MySQL later than 4.1.20, 5.0.22, 5.1.11; or that one is not using a GBK/Big5 connection encoding):

mysql_set_charset($charset);
mysql_query("SET SQL_MODE=''");
$var = mysql_real_escape_string('" OR 1=1 /*');
mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');

...because we've explicitly selected an SQL mode that doesn't include NO_BACKSLASH_ESCAPES.

mysql_set_charset($charset);
$var = mysql_real_escape_string("' OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

...because we're quoting our string literal with single-quotes.

$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(["' OR 1=1 /*"]);

...because PDO prepared statements are immune from this vulnerability (and ircmaxell's too, provided either that you're using PHP=5.3.6 and the character set has been correctly set in the DSN; or that prepared statement emulation has been disabled).

$var  = $pdo->quote("' OR 1=1 /*");
$stmt = $pdo->query("SELECT * FROM test WHERE name = $var LIMIT 1");

...because PDO's quote() function not only escapes the literal, but also quotes it (in single-quote ' characters); note that to avoid ircmaxell's bug in this case, you must be using PHP=5.3.6 and have correctly set the character set in the DSN.

$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "' OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

...because MySQLi prepared statements are safe.

Wrapping Up

Thus, if you:

• use native prepared statements

OR

• use MySQL v5.7.6 or later

OR

• in addition to employing one of the solutions in ircmaxell's summary, use at least one of:

  • PDO;
  • single-quoted string literals; or
  • an explicitly set SQL mode that does not include NO_BACKSLASH_ESCAPES

...then you should be completely safe (vulnerabilities outside the scope of string escaping aside).

Siddharth's answer is terrific.

However, this technique can hit trouble when working with a large set of data (my computer froze up on 50,000 rows). Some less processor-intensive methods:

Single uniqueness check

1. Sort by the two columns (A, B in this example)

2. Use a formula that looks at less data

   =IF(SUMPRODUCT(($A2:$A3=A2)*($B2:$B3=B2))>1,0,1) 
   

Multiple uniqueness checks

If you need to check uniqueness in different columns, you can't rely on two sorts.

Instead,

1. Sort single column (A)

2. Add formula covering the maximum number of records for each grouping. If ABC might have 50 rows, the formula will be

   =IF(SUMPRODUCT(($A2:$A49=A2)*($B2:$B49=B2))>1,0,1)
   

Here you go with modified data.json file:

{
    "maps": [
        {
            "id": "blabla",
            "iscategorical": "0"
        },
        {
            "id": "blabla",
            "iscategorical": "0"
        }
    ],
    "masks": [{
        "id": "valore"
    }],
    "om_points": "value",
    "parameters": [{
        "id": "valore"
    }]
}

You can call or print data on console by using below lines:

import json
from pprint import pprint
with open('data.json') as data_file:
    data_item = json.load(data_file)
pprint(data_item)

Expected output for print(data_item['parameters'][0]['id']):

{'maps': [{'id': 'blabla', 'iscategorical': '0'},
          {'id': 'blabla', 'iscategorical': '0'}],
 'masks': [{'id': 'valore'}],
 'om_points': 'value',
 'parameters': [{'id': 'valore'}]}

Expected output for print(data_item['parameters'][0]['id']):

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live(). Refer: http://api.jquery.com/on/

File format
This tool parses .CRX version 2 format documented by Google. In general, .CRX file format consist of few parts:

Magic header
Version of file format
Public Key information and a package signature Zipped contents of the extension source code Magic header is a signature of the file telling that this file is Chrome Extension. Using this header the operating system can determine the actual type of the file (MIME type is application/x-chrome-extension), and how should it be treaten (is it executable? is it a text file?). Then the window system can show beautiful icon to the user.

In .CRX files the magic header has a constant value Cr24 or 0x43723234.

The version is provided by vendor. The version bytes are 0x02000000.

The next part of the file contains the length of the public key information and the length of a digital signature.

All .CRX packages distributed via Chrome WebStore should have public key information and digital signature in order to make possible for browser to check that the package has been transmitted without modifications and that no additions or replacements were made.

After all of the header stuff, typically ending up on 307'th byte, comes the code of extension, stored as zip-archive. So the remainder of the .crx file is the well-known .zip archive.

.crx file opened in the hex editor called HexFiend (on Mac) The header part of a .crx file selected on the picture above. Obviously, you can extract the remaining .zip archive "by hand" using any simple hex editor. In this example, we use handy HexFiend editor on Mac.

The CRX Extractor loads a file provided, checks a magic header, version and trims the file, so only .zip archive remains. Then it returns obtained .zip archive to user.

Another way is to use the subplots function and pass the width ratio with gridspec_kw:

import numpy as np
import matplotlib.pyplot as plt 

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
f, (a0, a1) = plt.subplots(1, 2, gridspec_kw={'width_ratios': [3, 1]})
a0.plot(x, y)
a1.plot(y, x)

f.tight_layout()
f.savefig('grid_figure.pdf')

Its nothing more easy.

run command: ./gradlew clean -PjobId=9999

and

in gradle use: println(project.gradle.startParameter.projectProperties)

You will get clue.

If you use OmniFaces you can also use it's EL functions like of:formatDate() to format Date objects. You would use it like this:

<h:outputText value="#{of:formatDate(someBean.dateField, 'dd.MM.yyyy HH:mm')}" />

This way you can not only use it for output but also to pass it on to other JSF components.

If the file is native to your system (certainly no guarantees of that), then Node can help you out:

var os = require('os');

a.split(os.EOL);

This is usually more useful for constructing output strings from Node though, for platform portability.

The problem might be your split() call. Try just split(" ") without the square brackets.

http.get(options).on('response', function (response) {
    var body = '';
    var i = 0;
    response.on('data', function (chunk) {
        i++;
        body += chunk;
        console.log('BODY Part: ' + i);
    });
    response.on('end', function () {

        console.log(body);
        console.log('Finished');
    });
});

Changes to this, which works. Any comments?

So i tried all the suggested solutions to no avail. All i did was to set run the app from the server and it displayed the error in full, this should have worked when i set customErrors mode to false but it didn't. The moment i browsed the API form the server i was able to see the problem.

As explained above not just the db datatype it will also affect the view that will be generated if you are scaffolding. string will generate a text_field text will generate a text_area

If the column has a 0 value, you are fine, my guess is that you have a problem with a Null value, in that case you would need to use IsNull(Column, 0) to ensure it is always 0 at minimum.

Install a newer version of Eclipse, (Luna Release (4.4.0) or more recent), it include a great Dark theme by default.

Here is a screenshot :

Use the following JS:

$(document).ready(function () {
    $("#btnsubmit").click(function () {

             $.ajax({
                 type: "POST",
                 url: '/Plan/PlanManage',     //your action
                 data: $('#PlanForm').serialize(),   //your form name.it takes all the values of model               
                 dataType: 'json',
                 success: function (result) {
                     console.log(result);
                 }
             })
        return false;
    });
});

and the following code on your controller:

[HttpPost]
public string PlanManage(Plan objplan)  //model plan
{
}

This is what i've done works like a charm

            private static int _x=0, _y=0;
        private static Point _point;
        public static Point LocationInForm(Control c)
        {
            if (c.Parent == null) 
            {
                _x += c.Location.X;
                _y += c.Location.Y;
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;
            }
            else if ((c.Parent is System.Windows.Forms.Form))
            {
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;

There is an official implementation by Google: https://github.com/google/uuid

Generating a version 4 UUID works like this:

package main

import (
    "fmt"
    "github.com/google/uuid"
)

func main() {
    id := uuid.New()
    fmt.Println(id.String())
}

Try it here: https://play.golang.org/p/6YPi1djUMj9

Same problem, not sure why it occurred only after upgrading from Spring v3.2.x to v4.2.x.

Solved it by doing the following:

1. Clear all eclipse files [.classpath, .project, .settings/].
2. Perform >mvn eclipse:eclipse
3. Perform eclipse>project>properties>deployment assembly add [referenced projects, additional classpaths].

Publish and Start the module in Tomcat tab, it now starts properly.

One way assuming filtered data in A1 downwards;

dim Rng as Range
set Rng = Range("A2", Range("A2").End(xlDown)).Cells.SpecialCells(xlCellTypeVisible)
...
for each cell in Rng 
   ...     

library(tidyverse)

df_1 %>%
  group_by(Year, Month) %>%
  summarise(count= n()) 

The path must be via the URI (full).

Like: http://example.com/favicon.png

so in your case:

<!DOCTYPE html>
<html> 
    <head profile="http://www.w3.org/2005/10/profile">
        <title></title>
        <link rel="shortcut icon" 
              type="image/png" 
              href=" http://example.com/favicon.png" />
    </head>
    <body>
    </body>
</html>

Ref: http://www.w3.org/2005/10/howto-favicon

android:singleLine is now deprecated. From the documentation:

This constant was deprecated in API level 3.

This attribute is deprecated. Use maxLines instead to change the layout of a static text, and use the textMultiLine flag in the inputType attribute instead for editable text views (if both singleLine and inputType are supplied, the inputType flags will override the value of singleLine).

So you could just set android:inputType="textEmailSubject" or any other value that matches the content of the field.

Why so complicated? Your solution was almost right except it's a way easier to make the pattern transparent and the background color solid. PNG can contain transparencies. So use photoshop to make the pattern transparent by setting the layer to 70% and resaving your image. Then you only need one selector. Works cross browser.

CSS:

.background {
   background: url('../img/bg/diagonalnoise.png');/* transparent png image*/
   background-color: rgb(248, 247, 216);
}

HTML:

<div class="background">
   ...
</div> 

This are the basic. A usage example follows where I switched from background to background-image but both properties works the same.

body { margin: 0; }_x000D_
div {_x000D_
   height: 110px !important;_x000D_
   padding: 1em;_x000D_
   text-transform: uppercase;_x000D_
   font-family: Arial, Helvetica, sans-serif;_x000D_
   font-weight: 600;_x000D_
   color: white;_x000D_
   text-shadow: 0 0 2px #333;_x000D_
}_x000D_
.background {_x000D_
   background-image: url('https://www.transparenttextures.com/patterns/arabesque.png');/* transparent png image */_x000D_
   }_x000D_
.col-one {_x000D_
  background-color: rgb(255, 255, 0);_x000D_
}_x000D_
.col-two {_x000D_
  background-color: rgb(0, 255, 255);_x000D_
}_x000D_
.col-three {_x000D_
  background-color: rgb(0, 255, 0);_x000D_
}

<div class="background col-one">_x000D_
 1. Background_x000D_
</div> _x000D_
<div class="background col-two">_x000D_
 2. Background_x000D_
</div> _x000D_
<div class="background col-three">_x000D_
 3. Background_x000D_
</div> 

PLEASE WAIT A MINUTE! IT TAKES SOME TIME TO LOAD THE EXTERNAL PATTERNS.

This website seems to be rather slow...

sudo apt-get -y --reinstall install phpmyadmin;
sudo service apache2 restart;

Hope this helps.

Is there also a way to pass coords directly to google maps to display?

You can use the geo URI prefix:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("geo:" + latitude + "," + longitude));
startActivity(intent);

In css add this to the element:

margin-top: -15px; /*for exact positioning */
margin-top: -5%; /* for relative positioning */

you can use either one to position accordingly.

I'm writing an sp that could be useful for this purpose, basically this sp pivot any table and return a new table pivoted or return just the set of data, this is the way to execute it:

Exec dbo.rs_pivot_table @schema=dbo,@table=table_name,@column=column_to_pivot,@agg='sum([column_to_agg]),avg([another_column_to_agg]),',
        @sel_cols='column_to_select1,column_to_select2,column_to_select1',@new_table=returned_table_pivoted;

please note that in the parameter @agg the column names must be with '[' and the parameter must end with a comma ','

then Select * From ##TEMPORAL1PVT would return:

You can open the other file and type :r file_to_be_copied_from. Or you can buffer. Or go to the first file, go on the line you want to copy, type "qY, go to the file you want to paste and type "qP.

"buffer_name, copies to the buffer. Y is yank and P is put. Hope that helps!

here you go Sir :-)

I also encountered this problem, and I have to change the folder name from Chinese to English. Pity that current gradle build tool does not support Unicode names.

If you want to enable CORS without using filters or without config file just add

@CrossOrigin

to the top of your controller and it work.

This should help to get distinct values of a column:

df.select('column1').distinct().collect()

Note that .collect() doesn't have any built-in limit on how many values can return so this might be slow -- use .show() instead or add .limit(20) before .collect() to manage this.

I would recommend background-size: cover; if you don't want your background to lose its proportions: JS Fiddle

html { 
  background: url(image/path) no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

How to change orientation in some of the view

Instead of locking orientation of entire activity you can use this class to dynamically lock orientation from any of your view pragmatically:-

Make your view Landscape

OrientationUtils.lockOrientationLandscape(mActivity);

Make your view Portrait

OrientationUtils.lockOrientationPortrait(mActivity);

Unlock Orientation

OrientationUtils.unlockOrientation(mActivity);

Orientation Util Class

import android.app.Activity;
import android.content.Context;
import android.content.pm.ActivityInfo;

/*  * This class is used to lock orientation of android app in nay android devices 
 */

public class OrientationUtils {
    private OrientationUtils() {

    }

    /** Locks the device window in portrait mode. */
    public static void lockOrientationPortrait(Activity activity) {
        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

    /** Locks the device window in actual screen mode. */
    public static void lockOrientation(Activity activity) {

            }
        }
    }

    /** Unlocks the device window in user defined screen mode. */
    public static void unlockOrientation(Activity activity) {
