Description

There are many ways to validate your TextBox. You can do this on every keystroke, at a later time, or on the Validating event.

The Validating event gets fired if your TextBox looses focus. When the user clicks on a other Control, for example. If your set e.Cancel = true the TextBox doesn't lose the focus.

MSDN - Control.Validating Event When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), by calling the Select or SelectNextControl methods, or by setting the ContainerControl.ActiveControl property to the current form, focus events occur in the following order

Enter

GotFocus

Leave

Validating

Validated

LostFocus

When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:

Enter

GotFocus

LostFocus

Leave

Validating

Validated

Sample Validating Event

private void textBox1_Validating(object sender, CancelEventArgs e)
{
    if (textBox1.Text != "something")
        e.Cancel = true;
}

Update

You can use the ErrorProvider to visualize that your TextBox is not valid. Check out Using Error Provider Control in Windows Forms and C#

More Information

• MSDN - Control.Validating Event
• MSDN - ErrorProvider Component (Windows Forms)
• Using Error Provider Control in Windows Forms and C#

You should use append("svg:svg"), not append("svg") so that D3 makes the element with the correct 'namespace' if you're using xhtml.

Swift 4.2

Result:

testButton.on(.touchUpInside) { (sender, event) in
    // You can use any reference initialized before the code block here
    // You can access self by adding [weak self] before (sender, event)
    // You can then either make self strong by using a guard statement or use a optional operator (?)
    print("user did press test button")
}

In the file UIButton+Events.swift I've created an extension method for UIButton that binds a UIControl.Event to a completion handler called EventHandler:

import UIKit

fileprivate var bindedEvents: [UIButton:EventBinder] = [:]

fileprivate class EventBinder {

    let event: UIControl.Event
    let button: UIButton
    let handler: UIButton.EventHandler
    let selector: Selector

    required init(
        _ event: UIControl.Event,
        on button: UIButton,
        withHandler handler: @escaping UIButton.EventHandler
    ) {
        self.event = event
        self.button = button
        self.handler = handler
        self.selector = #selector(performEvent(on:ofType:))
        button.addTarget(self, action: self.selector, for: event)
    }

    deinit {
        button.removeTarget(self, action: selector, for: event)
        if let index = bindedEvents.index(forKey: button) {
            bindedEvents.remove(at: index)
        }
    }
}

private extension EventBinder {

    @objc func performEvent(on sender: UIButton, ofType event: UIControl.Event) {
        handler(sender, event)
    }
}

extension UIButton {

    typealias EventHandler = (UIButton, UIControl.Event) -> Void

    func on(_ event: UIControl.Event, handler: @escaping EventHandler) {
        bindedEvents[self] = EventBinder(event, on: self, withHandler: handler)
    }
}

The reason why I used a custom class for binding the event is to be able to dispose the reference later when the button is deintialised. This will prevent a possible memory leak from occurring. This wasn't possible within the UIButton its extension, because I'm not allowed to implement a property nor the deinit method.

Note a similar error such as:

standard_init_linux.go:211: exec user process caused "no such file or directory"

can happen if the architecture an image was built for does not match the one of your system. For instance, trying to run an image built for arm64 on a x86_64 machine can generate this error.

String.Format("{0:#,###.##}", value)

A more complex example from String Formatting in C#:

String.Format("{0:$#,##0.00;($#,##0.00);Zero}", value);

This will output “$1,240.00" if passed 1243.50. It will output the same format but in parentheses if the number is negative, and will output the string “Zero” if the number is zero.

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE(signup_date) = CURDATE()

A very similar construction is available in the language

**if <statement>; <evaluation> {
   [statements ...]
} else {
   [statements ...]
}*

*

i.e.

if path,err := os.Executable(); err != nil {
   log.Println(err)
} else {
   log.Println(path)
}

Easiest way:

Check in your logcat window - TOP RIGHT corner PAUSE button || (Pause receiving new logcat messages)

Few clicks + eventually restart eclipse (usually works in my case)

javascript provides a classList attribute for a node element in dom. Simply using

  element.classList

will return a object of form

  DOMTokenList {0: "class1", 1: "class2", 2: "class3", length: 3, item: function, contains: function, add: function, remove: function…}

The object has functions like contains, add, remove which you can use

Make use of these Structs to know useful info about the current device in Swift 3.0

struct ScreenSize { // Answer to OP's question

    static let SCREEN_WIDTH         = UIScreen.main.bounds.size.width
    static let SCREEN_HEIGHT        = UIScreen.main.bounds.size.height
    static let SCREEN_MAX_LENGTH    = max(ScreenSize.SCREEN_WIDTH, ScreenSize.SCREEN_HEIGHT)
    static let SCREEN_MIN_LENGTH    = min(ScreenSize.SCREEN_WIDTH, ScreenSize.SCREEN_HEIGHT)

}

struct DeviceType { //Use this to check what is the device kind you're working with

    static let IS_IPHONE_4_OR_LESS  = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH < 568.0
    static let IS_IPHONE_SE         = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 568.0
    static let IS_IPHONE_7          = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 667.0
    static let IS_IPHONE_7PLUS      = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 736.0
    static let IS_IPHONE_X          = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 812.0
    static let IS_IPAD              = UIDevice.current.userInterfaceIdiom == .pad && ScreenSize.SCREEN_MAX_LENGTH == 1024.0

}


struct iOSVersion { //Get current device's iOS version

    static let SYS_VERSION_FLOAT  = (UIDevice.current.systemVersion as NSString).floatValue
    static let iOS7               = (iOSVersion.SYS_VERSION_FLOAT >= 7.0 && iOSVersion.SYS_VERSION_FLOAT < 8.0)
    static let iOS8               = (iOSVersion.SYS_VERSION_FLOAT >= 8.0 && iOSVersion.SYS_VERSION_FLOAT < 9.0)
    static let iOS9               = (iOSVersion.SYS_VERSION_FLOAT >= 9.0 && iOSVersion.SYS_VERSION_FLOAT < 10.0)
    static let iOS10              = (iOSVersion.SYS_VERSION_FLOAT >= 10.0 && iOSVersion.SYS_VERSION_FLOAT < 11.0)
    static let iOS11              = (iOSVersion.SYS_VERSION_FLOAT >= 11.0 && iOSVersion.SYS_VERSION_FLOAT < 12.0)
    static let iOS12              = (iOSVersion.SYS_VERSION_FLOAT >= 12.0 && iOSVersion.SYS_VERSION_FLOAT < 13.0)

}

For all the good answers above, I'm just going to give a concrete example in Java servlet HttpSession class. Hope this example helps to clarify some question you may still have.

If you need to store and retrieve values for a session, you use setAttribute(String, Object), and getAttribute(String, Object) method. So for a boolean value, you are forced to use the Boolean class if you want to store it in an http session.

HttpSession sess = request.getSession(false);
Boolean isAdmin = (Boolean) sess.getAttribute("admin");
if (! isAdmin) ...

The last line will cause a NullPointerException if the attribute values is not set. (which is the reason led me to this post). So the 3 logic state is here to stay, whether you prefer to use it or not.

If you trust the data source, you can use eval to convert your string into a dictionary:

eval(your_json_format_string)

Example:

>>> x = "{'a' : 1, 'b' : True, 'c' : 'C'}"
>>> y = eval(x)

>>> print x
{'a' : 1, 'b' : True, 'c' : 'C'}
>>> print y
{'a': 1, 'c': 'C', 'b': True}

>>> print type(x), type(y)
<type 'str'> <type 'dict'>

>>> print y['a'], type(y['a'])
1 <type 'int'>

>>> print y['a'], type(y['b'])
1 <type 'bool'>

>>> print y['a'], type(y['c'])
1 <type 'str'>

AJAX is also a possibility. Effectively you would want data from the php page. Once you have the data you can format in anyway in javascript and display.

var xmlhttp = new XMLHttpRequest();
var url = "risingStars.php";

xmlhttp.onreadystatechange = function () {
    if (this.readyState == 4 && this.status == 200) {
        getDbData(this.responseText);
    }
}
xmlhttp.open("GET", url, true);
xmlhttp.send();


function getDbData(response) {

//do whatever you want with respone
}

Use Array.prototype.map() with an arrow function:

const arrayColumn = (arr, n) => arr.map(x => x[n]);_x000D_
_x000D_
const twoDimensionalArray = [_x000D_
  [1, 2, 3],_x000D_
  [4, 5, 6],_x000D_
  [7, 8, 9],_x000D_
];_x000D_
_x000D_
console.log(arrayColumn(twoDimensionalArray, 0));

Note: Array.prototype.map() and arrow functions are part of ECMAScript 6 and not supported everywhere, see ECMAScript 6 compatibility table.

You probably want unix2dos:

$ man unix2dos

NAME
       dos2unix - DOS/MAC to UNIX and vice versa text file format converter

SYNOPSIS
           dos2unix [options] [-c CONVMODE] [-o FILE ...] [-n INFILE OUTFILE ...]
           unix2dos [options] [-c CONVMODE] [-o FILE ...] [-n INFILE OUTFILE ...]

DESCRIPTION
       The Dos2unix package includes utilities "dos2unix" and "unix2dos" to convert plain text files in DOS or MAC format to UNIX format and vice versa.  Binary files and non-
       regular files, such as soft links, are automatically skipped, unless conversion is forced.

       Dos2unix has a few conversion modes similar to dos2unix under SunOS/Solaris.

       In DOS/Windows text files line endings exist out of a combination of two characters: a Carriage Return (CR) followed by a Line Feed (LF).  In Unix text files line
       endings exists out of a single Newline character which is equal to a DOS Line Feed (LF) character.  In Mac text files, prior to Mac OS X, line endings exist out of a
       single Carriage Return character. Mac OS X is Unix based and has the same line endings as Unix.

You can either run unix2dos on your DOS/Windows machine using cygwin or on your Mac using MacPorts.

This should help if you need a publicly exposed website but you're on a dev pc. Also to answer (I can't comment yet): "How do I post to an internal only running development server with this? – stryba "

NGROK creates a secure public URL to a local webserver on your development machine (Permanent URLs available for a fee, temporary for free).
1) Run ngrok.exe to open command line (on desktop)
2) Type ngrok.exe http 80 to start a tunnel,
3) test by browsing to the displayed web address which will forward and display the local default 80 page on your dev pc

Then use some of the tools recommended above to POST to your ngrok site ('https://xxxxxx.ngrok.io') to test your local code.

The const qualifier means that the methods can be called on any value of foobar. The difference comes when you consider calling a non-const method on a const object. Consider if your foobar type had the following extra method declaration:

class foobar {
  ...
  const char* bar();
}

The method bar() is non-const and can only be accessed from non-const values.

void func1(const foobar& fb1, foobar& fb2) {
  const char* v1 = fb1.bar();  // won't compile
  const char* v2 = fb2.bar();  // works
}

The idea behind const though is to mark methods which will not alter the internal state of the class. This is a powerful concept but is not actually enforceable in C++. It's more of a promise than a guarantee. And one that is often broken and easily broken.

foobar& fbNonConst = const_cast<foobar&>(fb1);

The ECMAscript standard does not specify which sort algorithm is to be used. Indeed, different browsers feature different sort algorithms. For example, Mozilla/Firefox's sort() is not stable (in the sorting sense of the word) when sorting a map. IE's sort() is stable.

I think this is exactly what you were looking for

http://today.java.net/pub/a/today/2007/06/26/generating-pdfs-with-flying-saucer-and-itext.html

http://code.google.com/p/flying-saucer

Flying Saucer's primary purpose is to render spec-compliant XHTML and CSS 2.1 to the screen as a Swing component. Though it was originally intended for embedding markup into desktop applications (things like the iTunes Music Store), Flying Saucer has been extended work with iText as well. This makes it very easy to render XHTML to PDFs, as well as to images and to the screen. Flying Saucer requires Java 1.4 or higher.

Example: button.titleLabel?.font = UIFont(name: "HelveticaNeue-Bold", size: 12)

• If you want to use defaul font from it's own family, use for example: "HelveticaNeue"
• If you want to specify family font, use for example: "HelveticaNeue-Bold"

This is one way to do it:

string = "this is a string"
ssplit = string.split()
for word in ssplit:
    print (word)

Output:

this
is
a
string

My status bar and navigation bar overlap after return from landscape view of YTPlayer. Here is my solution after trying @comonitos' version but not work on my iOS 8

- (void)fixNavigationBarPosition {
    if (self.navigationController) {
        CGRect frame = self.navigationController.navigationBar.frame;
        if (frame.origin.y != 20.f) {
            frame.origin.y = 20.f;
            self.navigationController.navigationBar.frame = frame;
        }
    }
}

Just call this function whenever you want to fix the position of navigation bar. I called on YTPlayerViewDelegate's playerView:didChangeToState:

- (void)playerView:(YTPlayerView *)playerView didChangeToState:(YTPlayerState)state {
    switch (state) {
        case kYTPlayerStatePaused:
        case kYTPlayerStateEnded:
            [self fixNavigationBarPosition];
            break;
        default:
    }
}

SELECT * FROM TABLE_NAME
where COLUMN_NAME <> '';

You can do

dt[, !c("V1","V2","V3","V5")]

to get

Rails scaffolds use 422 Unprocessable Entity for these kinds of errors. See RFC 4918 for more information.

The "Pull" app is an automatic set-up-and-forget solution. It will sync the default branch of your fork with the upstream repository.

Visit the URL, click the green "Install" button and select the repositories where you want to enable automatic synchronization.

The branch is updated once per hour directly on GitHub, on your local machine you need to pull the master branch to ensure that your local copy is in sync.

This problem is because of your https that means SSL certification. Try on Localhost.

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

http://jsfiddle.net/5b2eb/

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

Couldn't add this as a comment, but in case anyone is interested in using the accepted answer with subplots, the divider should be formed on specific axes object (rather than on the numpy.ndarray returned from plt.subplots)

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
data = np.arange(100, 0, -1).reshape(10, 10)
fig, ax = plt.subplots(ncols=2, nrows=2)
for row in ax:
    for col in row:
        im = col.imshow(data, cmap='bone')
        divider = make_axes_locatable(col)
        cax = divider.append_axes('right', size='5%', pad=0.05)
        fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

x=[1,2,3,4,5]
sum=0
for s in range(0,len(x)):
   sum=sum+x[s]
print sum   

You can also simply use

WORKDIR /var/www/app

It will automatically create the folders if they don't exist.

Then switch back to the directory you need to be in.

OK, there are two ways of doing that:

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

Your current code works, you can try it here: http://jsfiddle.net/s4UyH/

You have something outside the example triggering another .click(), check for other handlers that are also triggering a click event on that element.

$dayOfYear = today()->dayOfYear; $dayOfWeek = today('Europe/London')->dayOfWeek;

For most use cases, it's not correct to register MultipartFilter in web.xml because Spring MVC already does the work of processing your multipart request. It's even written in the filter's javadoc.

On the server side, define a multipartResolver bean in your app context:

@Bean
public CommonsMultipartResolver multipartResolver(){
    CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    commonsMultipartResolver.setMaxUploadSize(50000000);
    return commonsMultipartResolver;
}

On the client side, here's how to prepare the request for use with Spring RestTemplate API:

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    LinkedMultiValueMap<String, String> pdfHeaderMap = new LinkedMultiValueMap<>();
    pdfHeaderMap.add("Content-disposition", "form-data; name=filex; filename=" + file.getOriginalFilename());
    pdfHeaderMap.add("Content-type", "application/pdf");
    HttpEntity<byte[]> doc = new HttpEntity<byte[]>(file.getBytes(), pdfHeaderMap);

    LinkedMultiValueMap<String, Object> multipartReqMap = new LinkedMultiValueMap<>();
    multipartReqMap.add("filex", doc);

    HttpEntity<LinkedMultiValueMap<String, Object>> reqEntity = new HttpEntity<>(multipartReqMap, headers);
    ResponseEntity<MyResponse> resE = restTemplate.exchange(uri, HttpMethod.POST, reqEntity, MyResponse.class);

The important thing is really to provide a Content-disposition header using the exact case, and adding name and filename specifiers, otherwise your part will be discarded by the multipart resolver.

Then, your controller method can handle the uploaded file with the following argument:

@RequestParam("filex") MultipartFile file

Hope this helps.

I used JSONObject as shown below in Servlet.

    JSONObject jsonReturn = new JSONObject();

    NhAdminTree = AdminTasks.GetNeighborhoodTreeForNhAdministrator( connection, bwcon, userName);

    map = new HashMap<String, String>();
    map.put("Status", "Success");
    map.put("FailureReason", "None");
    map.put("DataElements", "2");

    jsonReturn = new JSONObject();
    jsonReturn.accumulate("Header", map);

    List<String> list = new ArrayList<String>();
    list.add(NhAdminTree);
    list.add(userName);

    jsonReturn.accumulate("Elements", list);

The Servlet returns this JSON object as shown below:

    response.setContentType("application/json");
    response.getWriter().write(jsonReturn.toString());

This Servlet is called from Browser using AngularJs as below

$scope.GetNeighborhoodTreeUsingPost = function(){
    alert("Clicked GetNeighborhoodTreeUsingPost : " + $scope.userName );

    $http({

        method: 'POST',
        url : 'http://localhost:8080/EPortal/xlEPortalService',
        headers: {
           'Content-Type': 'application/json'
         },
        data : {
            'action': 64,
            'userName' : $scope.userName
        }
    }).success(function(data, status, headers, config){
        alert("DATA.header.status : " + data.Header.Status);
        alert("DATA.header.FailureReason : " + data.Header.FailureReason);
        alert("DATA.header.DataElements : " + data.Header.DataElements);
        alert("DATA.elements : " + data.Elements);

    }).error(function(data, status, headers, config) {
        alert(data + " : " + status + " : " + headers + " : " + config);
    });

};

This code worked and it is showing correct data in alert dialog box:

Data.header.status : Success

Data.header.FailureReason : None

Data.header.DetailElements : 2

Data.Elements : Coma seperated string values i.e. NhAdminTree, userName

Nick Vogt at H3XED posted this syntax: https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Take this link and replace the expression "VIDEOID" with the (shortened/shared) ID of the video.

Exapmple for ID: i3jNECZ3ybk looks like this: ... /v/i3jNECZ3ybk?version=3&vq=hd1080

What you get as a result is the standalone 1080p video but not in the Tube environment.

I had the same problem, also in my XCTestCase files, but not in the regular project files.

To get rid of the:

Use of unresolved identifier 'PrimeNumberModel'

I needed to import the base module in the test file. In my case, my target is called 'myproject' and I added import myproject and the class was recognised.

I would do something like this:

function getCookie(cookie){
  return cookie
    .trim()
    .split(';')
    .map(function(line){return line.split(',');})
    .reduce(function(props,line) {
      var name = line[0].slice(0,line[0].search('='));
      var value = line[0].slice(line[0].search('='));
      props[name] = value;
      return props;
    },{})
}

This will return your cookie as an object.

And then you can call it like this:

getCookie(document.cookie)['shares']

SELECT SUBSTR('299123456789',DECODE(least(LENGTH('299123456789'),9),9,-9,LENGTH('299123456789')*-1)) value from dual  

Gives 123456789

The same statement works even when the number is less than 9 digits:

SELECT SUBSTR('6789',DECODE(least(LENGTH('6789'),9),9,-9,LENGTH('6789')*-1)) value from dual  

Gives 6789

I know this is a very old thread but I had the same problem which was due spaces in the images names.

e.g.

Image name: "hello o.jpg"

weirdly, by removing the spaces the function worked just fine.

Image name: "hello_o.jpg"

The following requires you to list the keys on your own, but at least TypeScript will enforce IUserProfile and IUserProfileKeys have the exact same keys (Required<T> was added in TypeScript 2.8):

export interface IUserProfile  {
  id: string;
  name: string;
};
type KeysEnum<T> = { [P in keyof Required<T>]: true };
const IUserProfileKeys: KeysEnum<IUserProfile> = {
  id: true,
  name: true,
};

Above posts answers questions related to URL Encoding and How it works, but the original questions was "Should I URL-encode POST data?" which isn't answered.

From my recent experience with URL Encoding, I would like to extend the question further. "Should I URL-encode POST data, same as GET HTTP method. Generally, HTML Forms over the Browser if are filled, submitted and/or GET some information, Browsers will do URL Encoding but If an application exposes a web-service and expects Consumers to do URL-Encoding on data, is it Architecturally and Technically correct to do URL Encode with POST HTTP method ?"

Pawel Sawicz .NET blog has a real good explanation and example code, explaining how to call the library;

GET:

var client = new RestClient("192.168.0.1");
var request = new RestRequest("api/item/", Method.GET);
var queryResult = client.Execute<List<Items>>(request).Data;

POST:

var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/", Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddBody(new Item
{
   ItemName = someName,
   Price = 19.99
});
client.Execute(request);

DELETE:

var item = new Item(){//body};
var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/{id}", Method.DELETE);
request.AddParameter("id", idItem);
 
client.Execute(request)

The RestSharp GitHub page has quite an exhaustive sample halfway down the page. To get started install the RestSharp NuGet package in your project, then include the necessary namespace references in your code, then above code should work (possibly negating your need for a full example application).

I typically bind this data using the RowDatabound event with the GridView:

protected void FormatGridView(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow) 
   {
      ((Button)e.Row.Cells(0).FindControl("btnSpecial")).CommandArgument = e.Row.RowIndex.ToString();
   }
}

The easiest way would be

Section = 'Sec_' + Section

But for efficiency, see: https://waymoot.org/home/python_string/

D = {} is a dictionary not set.

>>> d = {}
>>> type(d)
<type 'dict'>

Use D = set():

>>> d = set()
>>> type(d)
<type 'set'>
>>> d.update({1})
>>> d.add(2)
>>> d.update([3,3,3])
>>> d
set([1, 2, 3])

In the jar file you could just add this to your manifest.mft

Main-Class : A

The jar file would then be executable and would call the correct main.

On how to do this in Netbeans you can look at this: Producing executable jar in NetBeans

Handling polymorphism is either model-bound or requires lots of code with various custom deserializers. I'm a co-author of a JSON Dynamic Deserialization Library that allows for model-independent json deserialization library. The solution to OP's problem can be found below. Note that the rules are declared in a very brief manner.

public class SOAnswer {
    @ToString @Getter @Setter

        // create a deserializer instance
        DynamicObjectDeserializer deserializer = new DynamicObjectDeserializer();
        
        // runtime-configure deserialization rules; 
        // condition is bound to the existence of a field, but it could be any Predicate
        deserializer.addRule(DeserializationRuleFactory.newRule(1, 
                (e) -> e.getJsonNode().has("breed"),
                DeserializationActionFactory.objectToType(Dog.class)));
        
        deserializer.addRule(DeserializationRuleFactory.newRule(1,

the best way to uninstall VS 2010 is to use Microsoft Visual Studio 2010 Uninstall Utility on this link http://archive.msdn.microsoft.com/Project/Download/FileDownload.aspx?ProjectName=vs2010uninstall&DownloadId=11182

The best way around this is (and many other situations) in my experience, is to use cntlm which is a local no-authentication proxy which points to a remote authentication proxy. You can then just set WinHTTP to point to your local CNTLM (usually localhost:3128), and you can set CNTLM itself to point to the remote authentication proxy. CNTLM has a "magic NTLM dialect detection" option which generates password hashes to be put into the CNTLM configuration files.

To add exact fontsize you can use following. Worked for me since in my case predefined ranges (Large, tiny) are not match with the font size required to me.

\fontsize{10}{12}\selectfont This is the text you need to be in 10px

More info: https://tug.org/TUGboat/tb33-3/tb105thurnherr.pdf

You can simply do:

base=$(basename "$fspec")

Another approach instead of saving the file on the server and retrieving it, is to use .NET 4.0+ ObjectCache with a short expiration until the second Action (at which time it can be definitively dumped). The reason that I want to use JQuery Ajax to do the call, is that it is asynchronous. Building my dynamic PDF file takes quite a bit of time, and I display a busy spinner dialog during that time (it also allows other work to be done). The approach of using the data returned in the "success:" to create a Blob does not work reliably. It depends on the content of the PDF file. It is easily corrupted by data in the response, if it is not completely textual which is all that Ajax can handle.

if you need it in rails you can use first (source code)

'1234567890'.first(5) # => "12345"

there is also last (source code)

'1234567890'.last(2) # => "90"

alternatively check from/to (source code):

"hello".from(1).to(-2) # => "ell"

Disable the firewall and try to connect.

If that works, then enable the firewall and

Windows Defender Firewall -> Advanced Settings -> Inbound Rules(Right Click) -> New Rules -> Port -> Allow Port 1433 (Public and Private) -> Add

Do the same for Outbound Rules.

Then Try again.

Sometimes you need to reset ADB. To do that, in Eclipse, go:

Window>> Show View >> Android (Might be found in the "Other" option)>>Devices

in the device Tab, click the down arrow, and choose reset adb.

For Windows 7 and above go to C:\Users\USERNAME\.android folder and follow below steps:

1. Right click > create a new txt file with name repositories.txt
2. Open the file and go to File > Save As.. > select Save as type: All Files
3. Rename repositories.txt to repositories.cfg

To remove all doted outline, including those in bootstrap themes.

a, a:active, a:focus, 
button, button:focus, button:active, 
.btn, .btn:focus, .btn:active:focus, .btn.active:focus, .btn.focus, .btn.focus:active, .btn.active.focus {
    outline: none;
    outline: 0;
}

input::-moz-focus-inner {
    border: 0;
}

Note: You should add link href for bootstrap css before the main css, so bootstrap doesn't override your style.

It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.

Look at the definition of sys.all_parameters:

default_value sql_variant If has_default_value is 1, the value of this column is the value of the default for the parameter; otherwise, NULL.

That is, whatever the default for a parameter is, it has to fit in that column.

As Alex K pointed out in the comments, you can just do:

CREATE PROCEDURE [dbo].[problemParam] 
    @StartDate INT = NULL,
    @EndDate INT = NULL
AS  
BEGIN
   SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))

provided that NULL isn't intended to be a valid value for @StartDate.

As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE() within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.

Another approach would be to have an array of objects, with each individual object holding the properties of a column. This slightly changes the structure of "myMappings", but makes it easy to work with:

var myMappings = [
    { title: "Name", width: "10%" },
    { title: "Phone", width: "10%" },
    { title: "Address", width: "50%" },
    { title: "Zip", width: "10%" },
    { title: "Comments", width: "20%" }
];

Then you could easily iterate through all your "columns" with a for loop:

for (var i = 0; i < myMappings.length; i += 1) {
    // myMappings[i].title ...
    // myMappings[i].width ...
}

for python2 use:

py -2 -m pip install beautifulsoup4

Update to the answer

    // Get stack trace for the exception with source file information
    var st = new StackTrace(ex, true);
    // Get the top stack frame
    var frame = st.GetFrame(st.FrameCount-1);
    // Get the line number from the stack frame
    var line = frame.GetFileLineNumber();

Obviously that os.chdir('..') is the right answer here. But just FYI, if in the future you come across situation when you have to extensively manipulate directories and paths, here is a great package (Unipath) which lets you treat them as Python objects: https://pypi.python.org/pypi/Unipath

so that you could do something like this:

>>> from unipath import Path
>>> p = Path("/usr/lib/python2.5/gopherlib.py")
>>> p.parent
Path("/usr/lib/python2.5")
>>> p.name
Path("gopherlib.py")
>>> p.ext
'.py'

The answer

$scope.$watch('$viewContentLoaded', 
    function() { 
        $timeout(function() {
            //do something
        },0);    
});

is the only one that works in most scenarios I tested. In a sample page with 4 components all of which build HTML from a template, the order of events was

$document ready
$onInit
$postLink
(and these 3 were repeated 3 more times in the same order for the other 3 components)
$viewContentLoaded (repeated 3 more times)
$timeout execution (repeated 3 more times)

So a $document.ready() is useless in most cases since the DOM being constructed in angular may be nowhere near ready.

But more interesting, even after $viewContentLoaded fired, the element of interest still could not be found.

Only after the $timeout executed was it found. Note that even though the $timeout was a value of 0, nearly 200 milliseconds elapsed before it executed, indicating that this thread was held off for quite a while, presumably while the DOM had angular templates added on a main thread. The total time from the first $document.ready() to the last $timeout execution was nearly 500 milliseconds.

In one extraordinary case where the value of a component was set and then the text() value was changed later in the $timeout, the $timeout value had to be increased until it worked (even though the element could be found during the $timeout). Something async within the 3rd party component caused a value to take precedence over the text until sufficient time passed. Another possibility is $scope.$evalAsync, but was not tried.

I am still looking for that one event that tells me the DOM has completely settled down and can be manipulated so that all cases work. So far an arbitrary timeout value is necessary, meaning at best this is a kludge that may not work on a slow browser. I have not tried JQuery options like liveQuery and publish/subscribe which may work, but certainly aren't pure angular.

With query syntax:

var values =
from inner in outer
from value in inner
select value;

It can be:

echo "Welcome".$_POST['firstname'].$_POST['lastname'];

It should be mentioned that the Socket instance in both client and the server end needs to explicitly invoke close(). If only one of the ends invokes close() then too, the socket will remain in CLOSE_WAIT state.

Here is my utility class, you may use:

package <removed>;
import com.google.protobuf.Message;
import com.google.protobuf.MessageOrBuilder;
import com.google.protobuf.util.JsonFormat;
/**

        Model.Person res = personSvc.update(reqObj);
        final String resJson = ProtoUtil.toJson(res);
 **/
public class ProtoUtil {
    public static <T extends Message> String toJson(T obj){
        try{
            return JsonFormat.printer().print(obj);
        }catch(Exception e){
            throw new RuntimeException("Error converting Proto to json", e);
        }
    }
   public static <T extends MessageOrBuilder> T toProto(String protoJsonStr, T message){
        try{
            Message.Builder builder = message.getDefaultInstanceForType().toBuilder();
            JsonFormat.parser().ignoringUnknownFields().merge(protoJsonStr,builder);
            T out = (T) builder.build();
            return out;
        }catch(Exception e){

        }
    }
}

Following redsquare: You should not use in href attribute javascript code like "javascript:void();" - it is wrong. Better use for example href="#" and then in Your event handler as a last command: "return false;". And even better - use in href correct link - if user have javascript disabled, web browser follows the link - in this case Your webpage should reload with input filled with value of that link.

    //create TreeMap instance
    TreeMap treeMap = new TreeMap();

    //add key value pairs to TreeMap
    treeMap.put("1","One");
    treeMap.put("2","Two");
    treeMap.put("3","Three");

    /*
      get Collection of values contained in TreeMap using
      Collection values()        
    */
    Collection c = treeMap.values();

    //obtain an Iterator for Collection
    Iterator itr = c.iterator();

    //iterate through TreeMap values iterator
    while(itr.hasNext())
      System.out.println(itr.next());

or:

   for (Map.Entry<K,V> entry : treeMap.entrySet()) {
        V value = entry.getValue();
        K key = entry.getKey();
   }

or:

   // Use iterator to display the keys and associated values
   System.out.println("Map Values Before: ");
   Set keys = map.keySet();
   for (Iterator i = keys.iterator(); i.hasNext();) {
     Integer key = (Integer) i.next();
     String value = (String) map.get(key);
     System.out.println(key + " = " + value);
   }

Try to check for existence:

IF NOT EXISTS (SELECT * FROM dbo.Employee WHERE ID = @SomeID)

    INSERT INTO dbo.Employee(Col1, ..., ColN)
    VALUES(Val1, .., ValN)

ELSE

    UPDATE dbo.Employee
    SET Col1 = Val1, Col2 = Val2, ...., ColN = ValN
    WHERE ID = @SomeID

You could easily wrap this into a stored procedure and just call that stored procedure from the outside (e.g. from a programming language like C# or whatever you're using).

Update: either you can just write this entire statement in one long string (doable - but not really very useful) - or you can wrap it into a stored procedure:

CREATE PROCEDURE dbo.InsertOrUpdateEmployee
       @ID INT,
       @Name VARCHAR(50),
       @ItemName VARCHAR(50),  
       @ItemCatName VARCHAR(50),
       @ItemQty DECIMAL(15,2)
AS BEGIN
    IF NOT EXISTS (SELECT * FROM dbo.Table1 WHERE ID = @ID)
       INSERT INTO dbo.Table1(ID, Name, ItemName, ItemCatName, ItemQty)
       VALUES(@ID, @Name, @ItemName, @ItemCatName, @ItemQty)
    ELSE
       UPDATE dbo.Table1
       SET Name = @Name,
           ItemName = @ItemName,
           ItemCatName = @ItemCatName,
           ItemQty = @ItemQty
       WHERE ID = @ID
END

and then just call that stored procedure from your ADO.NET code

Try to implement FirebaseInstanceIdService to get refresh token.

Access the registration token:

You can access the token's value by extending FirebaseInstanceIdService. Make sure you have added the service to your manifest, then call getToken in the context of onTokenRefresh, and log the value as shown:

     @Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

Full Code:

   import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;


public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private static final String TAG = "MyFirebaseIIDService";

    /**
     * Called if InstanceID token is updated. This may occur if the security of
     * the previous token had been compromised. Note that this is called when the InstanceID token
     * is initially generated so this is where you would retrieve the token.
     */
    // [START refresh_token]
    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);

        // TODO: Implement this method to send any registration to your app's servers.
        sendRegistrationToServer(refreshedToken);
    }
    // [END refresh_token]

    /**
     * Persist token to third-party servers.
     *
     * Modify this method to associate the user's FCM InstanceID token with any server-side account
     * maintained by your application.
     *
     * @param token The new token.
     */
    private void sendRegistrationToServer(String token) {
        // Add custom implementation, as needed.
    }
}

See my answer here.

EDITS:

You shouldn't be starting a FirebaseInstanceIdService yourself.

It will Called when the system determines that the tokens need to be refreshed. The application should call getToken() and send the tokens to all application servers.

This will not be called very frequently, it is needed for key rotation and to handle Instance ID changes due to:

• App deletes Instance ID
• App is restored on a new device User
• uninstalls/reinstall the app
• User clears app data

The system will throttle the refresh event across all devices to avoid overloading application servers with token updates.

Try below way:

you'd call FirebaseInstanceID.getToken() anywhere off your main thread (whether it is a service, AsyncTask, etc), store the returned token locally and send it to your server. Then whenever onTokenRefresh() is called, you'd call FirebaseInstanceID.getToken() again, get a new token, and send that up to the server (probably including the old token as well so your server can remove it, replacing it with the new one).

There are a few issues in your code

• <div [formGroup]="form"> outside of a <form> tag
• <form [formGroup]="form"> but the name of the property containing the FormGroup is loginForm therefore it should be <form [formGroup]="loginForm">
• [formControlName]="dob" which passes the value of the property dob which doesn't exist. What you need is to pass the string dob like [formControlName]="'dob'" or simpler formControlName="dob"

Plunker example

Non-javascript way . . aspx page:

 <form id="form1" runat="server">
<div>
    <asp:CheckBox ID="CheckBox1" runat="server" />
    <asp:CustomValidator ID="CustomValidator1"
        runat="server" ErrorMessage="CustomValidator" ControlToValidate="CheckBox1"></asp:CustomValidator>
</div>
</form>

Code Behind:

Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
    If Not CheckBox1.Checked Then
        args.IsValid = False
    End If
End Sub

For any actions you might need (business Rules):

If Page.IsValid Then
   'do logic
End If 

Sorry for the VB code . . . you can convert it to C# if that is your pleasure. The company I am working for right now requires VB :(

You have to execute your query and add single quote to $email in the query beacuse it's a string, and remove the is_resource($query) $query is a string, the $result will be the resource

$query = "SELECT `email` FROM `tblUser` WHERE `email` = '$email'";
$result = mysqli_query($link,$query); //$link is the connection

if(mysqli_num_rows($result) > 0 ){....}

UPDATE

Base in your edit just change:

if(is_resource($query) && mysqli_num_rows($query) > 0 ){
        $query = mysqli_fetch_assoc($query);
        echo $email . " email exists " .  $query["email"] . "\n";

By

if(is_resource($result) && mysqli_num_rows($result) == 1 ){
        $row = mysqli_fetch_assoc($result);
         echo $email . " email exists " .  $row["email"] . "\n";

and you will be fine

UPDATE 2

A better way should be have a Store Procedure that execute the following SQL passing the Email as Parameter

SELECT IF( EXISTS (
                  SELECT *
                  FROM `Table`
                  WHERE `email` = @Email)
          , 1, 0) as `Exist`

and retrieve the value in php

Pseudocodigo:

 $query = Call MYSQL_SP($EMAIL);
 $result = mysqli_query($conn,$query);
 $row = mysqli_fetch_array($result)
 $exist = ($row['Exist']==1)? 'the email exist' : 'the email doesnt exist';

Adding to Alex's answer and simplifying it:

Objects are more strict with their use and hence gives the programmer more compile time "evaluation" power and hence in a lot of cases provide more "checking capability" and coould prevent any leaks, whereas any is a more generic term and a lot of compile time checks might hence be ignored.

Django 2.1.1 The primary answer got me halfway to answering my question. It did not help me save the result to a field in my actual model. In my case I wanted a textfield that a user could enter data into, then when a save occurred the data would be processed and the result put into a field in the model and saved. While the original answer showed how to get the value from the extra field, it did not show how to save it back to the model at least in Django 2.1.1

This takes the value from an unbound custom field, processes, and saves it into my real description field:

class WidgetForm(forms.ModelForm):
    extra_field = forms.CharField(required=False)

    def processData(self, input):
        # example of error handling
        if False:
            raise forms.ValidationError('Processing failed!')

        return input + " has been processed"

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)

        # self.description = "my result" note that this does not work

        # Get the form instance so I can write to its fields
        instance = super(WidgetForm, self).save(commit=commit)

        # this writes the processed data to the description field
        instance.description = self.processData(extra_field)

        if commit:
            instance.save()

        return instance

    class Meta:
        model = Widget
        fields = "__all__"

public class JSONConvector {

    public static String toJSON(Object object) throws JSONException, IllegalAccessException {
        String str = "";
        Class c = object.getClass();
        JSONObject jsonObject = new JSONObject();
        for (Field field : c.getDeclaredFields()) {
            field.setAccessible(true);
            String name = field.getName();
            String value = String.valueOf(field.get(object));
            jsonObject.put(name, value);
        }
        System.out.println(jsonObject.toString());
        return jsonObject.toString();
    }


    public static String toJSON(List list ) throws JSONException, IllegalAccessException {
        JSONArray jsonArray = new JSONArray();
        for (Object i : list) {
            String jstr = toJSON(i);
            JSONObject jsonObject = new JSONObject(jstr);
            jsonArray.put(jsonArray);
        }
        return jsonArray.toString();
    }
}

Install LXML parser in python environment.

pip install lxml

Your problem will be resolve. You can also use built-in python package for the same as:

soup = BeautifulSoup(s,  "html.parser")

Note: The "HTMLParser" module has been renamed to "html.parser" in Python3

You can use

String [] strArr = Str.split("");

This is by far the best post for exporting to excel from SQL:

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926

To quote from user madhivanan,

Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel

Create an Excel file named testing having the headers same as that of table columns and use these queries

1 Export data to existing EXCEL file from SQL Server table

insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;', 
    'SELECT * FROM [SheetName$]') select * from SQLServerTable

2 Export data from Excel to new SQL Server table

select * 
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [Sheet1$]')

3 Export data from Excel to existing SQL Server table (edited)

Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [SheetName$]')

4 If you dont want to create an EXCEL file in advance and want to export data to it, use

EXEC sp_makewebtask 
    @outputfile = 'd:\testing.xls', 
    @query = 'Select * from Database_name..SQLServerTable', 
    @colheaders =1, 
    @FixedFont=0,@lastupdated=0,@resultstitle='Testing details'

(Now you can find the file with data in tabular format)

5 To export data to new EXCEL file with heading(column names), create the following procedure

create procedure proc_generate_excel_with_columns
(
    @db_name    varchar(100),
    @table_name varchar(100),   
    @file_name  varchar(100)
)
as

--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select 
    @columns=coalesce(@columns+',','')+column_name+' as '+column_name 
from 
    information_schema.columns
where 
    table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')

--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'

--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)

--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)

--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)

--Delete dummy file 
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)

After creating the procedure, execute it by supplying database name, table name and file path:

EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'

Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.

Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.

To update single cells

A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?

This is the principle of how you do manage that

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = -99

You can also add formulas to Excel using this:

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = '=a7+c7'

Exporting with column names using T-SQL

Member Mladen Prajdic also has a blog entry on how to do this here

References: www.sqlteam.com (btw this is an excellent blog / forum for anyone looking to get more out of SQL Server). For error referencing I used this

Errors that may occur

If you get the following error:

OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries

Then run this:

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

Would suggest NOT using INSERT IGNORE as it ignores ALL errors (ie its a sloppy global ignore). Instead, since in your example tag is the unique key, use:

INSERT INTO table_tags (tag) VALUES ('tag_a'),('tab_b'),('tag_c') ON DUPLICATE KEY UPDATE tag=tag;

on duplicate key produces:

Query OK, 0 rows affected (0.07 sec)

SWIFT 5

If you don't have a ViewController set as the initial ViewController in storyboard, you need to do 2 things:

1. Go to your project TARGETS, select your project -> General -> Clear the Main Interface field.
2. Always inside project TARGETS, now go to Info -> Application Scene Manifest -> Scene Configuration -> Application Session Role -> Item0 (Default Configuration) -> delete the storyboard name field.

Finally, you can now add your code in SceneDelegate:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
    // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
    // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
    guard let windowScene = (scene as? UIWindowScene) else { return }

    window = UIWindow(windowScene: windowScene)


    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    // Make sure you set an Storyboard ID for the view controller you want to instantiate
    window?.rootViewController = storyboard.instantiateViewController(withIdentifier: identifier)
    window?.makeKeyAndVisible()

}

Just iterate over DataFrame.columns, now this is an example in which you will end up with a list of column names that match:

import pandas as pd

data = {'spike-2': [1,2,3], 'hey spke': [4,5,6], 'spiked-in': [7,8,9], 'no': [10,11,12]}
df = pd.DataFrame(data)

spike_cols = [col for col in df.columns if 'spike' in col]
print(list(df.columns))
print(spike_cols)

Output:

['hey spke', 'no', 'spike-2', 'spiked-in']
['spike-2', 'spiked-in']

Explanation:

1. df.columns returns a list of column names
2. [col for col in df.columns if 'spike' in col] iterates over the list df.columns with the variable col and adds it to the resulting list if col contains 'spike'. This syntax is list comprehension.

If you only want the resulting data set with the columns that match you can do this:

df2 = df.filter(regex='spike')
print(df2)

Output:

   spike-2  spiked-in
0        1          7
1        2          8
2        3          9

declare @d1 datetime, @d2 datetime
select @d1 = '4/19/2017',  @d2 = '5/7/2017'

DECLARE @Counter int = datediff(DAY,@d1 ,@d2 )

DECLARE @C int = 0
DECLARE @SUM int = 0





 WHILE  @Counter > 0
  begin
 SET @SUM = @SUM + IIF(DATENAME(dw, 

 DATEADD(day,@c,@d1))IN('Sunday','Monday','Tuesday','Wednesday','Thursday')
 ,1,0)



SET @Counter = @Counter - 1
set @c = @c +1

SFINAE only works if substitution in argument deduction of a template argument makes the construct ill-formed. There is no such substitution.

I thought of that too and tried to use std::is_same< T, int >::value and ! std::is_same< T, int >::value which gives the same result.

That's because when the class template is instantiated (which happens when you create an object of type Y<int> among other cases), it instantiates all its member declarations (not necessarily their definitions/bodies!). Among them are also its member templates. Note that T is known then, and !std::is_same< T, int >::value yields false. So it will create a class Y<int> which contains

class Y<int> {
    public:
        /* instantiated from
        template < typename = typename std::enable_if< 
          std::is_same< T, int >::value >::type >
        T foo() {
            return 10;
        }
        */

        template < typename = typename std::enable_if< true >::type >
        int foo();

        /* instantiated from

        template < typename = typename std::enable_if< 
          ! std::is_same< T, int >::value >::type >
        T foo() {
            return 10;
        }
        */

        template < typename = typename std::enable_if< false >::type >
        int foo();
};

The std::enable_if<false>::type accesses a non-existing type, so that declaration is ill-formed. And thus your program is invalid.

You need to make the member templates' enable_if depend on a parameter of the member template itself. Then the declarations are valid, because the whole type is still dependent. When you try to call one of them, argument deduction for their template arguments happen and SFINAE happens as expected. See this question and the corresponding answer on how to do that.

The string is a .NET string so you can use .NET methods. In your case:

$index = "The string".IndexOf(" ")

will return 3, which is the first occurrence of space in the string. For more information see: http://msdn.microsoft.com/en-us/library/system.string.aspx

For your need try something like:

$s.SubString($s.IndexOf("_") + 1, $s.LastIndexOf(".") - $s.IndexOf("_") - 1)

Or you could use regexps:

if ($s -Match '(_)(.*)(\.)[^.]*$') {  $matches[2] }

(has to be adjusted depending on exactly what you need).

I feel like adding more details to the existing answer:

NEVER EVER use a selector like DATE(datecolumns) = '2012-12-24' - it is a performance killer:

• it will calculate DATE() for all rows, including those, that don't match
• it will make it impossible to use an index for the query

It is much faster to use

SELECT * FROM tablename 
WHERE columname BETWEEN '2012-12-25 00:00:00' AND '2012-12-25 23:59:59'

as this will allow index use without calculation.

EDIT

As pointed out by Used_By_Already, in the time since the inital answer in 2012, there have emerged versions of MySQL, where using '23:59:59' as a day end is no longer safe. An updated version should read

SELECT * FROM tablename 
WHERE columname >='2012-12-25 00:00:00'
AND columname <'2012-12-26 00:00:00'

The gist of the answer, i.e. the avoidance of a selector on a calculated expression, of course still stands.

First of all, your code works and that's a valid way of creating a function in JavaScript (jQuery aside), but because you are declaring a function inside another function (an anonymous one in this case) "MyBlah" will not be accessible from the global scope.

Here's an example:

$(document).ready( function () {

    var MyBlah = function($blah) { alert($blah);  };

    MyBlah("Hello this works") // Inside the anonymous function we are cool.

 });

MyBlah("Oops") //This throws a JavaScript error (MyBlah is not a function)

This is (sometimes) a desirable behavior since we do not pollute the global namespace, so if your function does not need to be called from other part of your code, this is the way to go.

Declaring it outside the anonymous function places it in the global namespace, and it's accessible from everywhere.

Lastly, the $ at the beginning of the variable name is not needed, and sometimes used as a jQuery convention when the variable is an instance of the jQuery object itself (not necessarily in this case).

Maybe what you need is creating a jQuery plugin, this is very very easy and useful as well since it will allow you to do something like this:

$('div#message').myBlah("hello")

Either KeyDown or KeyUp.

TextBox tb = new TextBox();
tb.KeyDown += new KeyEventHandler(tb_KeyDown);

static void tb_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        //enter key is down
    }
}

i solved this problem by changing jre required for server (in my case is tomcat). From Server tab in eclipse, double click on the server (in order to open page for server configuration), click on Runtime environment, then change JRE required

Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:

• Prepare your proxy server - install IIS, Apache
• Get valid SSL certificate to avoid security errors (free from startssl.com for example)
• Write a wrapper, which will download insecure content (how to below)
• From your site/app get https://yourproxy.com/?page=http://insecurepage.com

If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

There is no native IF/ELSE for CSS available. CSS preprocessors like SASS (and Compass) can help, but if you’re looking for more feature-specific if/else conditions you should give Modernizr a try. It does feature-detection and then adds classes to the HTML element to indicate which CSS3 & HTML5 features the browser supports and doesn’t support. You can then write very if/else-like CSS right in your CSS without any preprocessing, like this:

.geolocation #someElem {
   /* only apply this if the browser supports Geolocation */
}
.no-geolocation #someElem {
   /* only apply this if the browser DOES NOT support Geolocation */
}

Keep in mind that you should always progressively enhance, so rather than the above example (which illustrates the point better), you should write something more like this:

#someElem {
   /* default styles, suitable for both Geolocation support and lack thereof */
}
.geolocation #someElem {
   /* only properties as needed to overwrite the default styling  */
}

Note that Modernizr does rely on JavaScript, so if JS is disabled you wouldn’t get anything. Hence the progressive enhancement approach of #someElem first, as a no-js foundation.

If you don't mind using NumPy, then:

In [319]: real = np.array([1234.5678])

In [327]: integ, deci = int(np.floor(real)), np.asscalar(real % 1)

In [328]: integ, deci
Out[328]: (1234, 0.5678000000000338)

The answer of delfuego is the simplest way to solve the certificate problem. But, in my case, one of our third party url (using https), updated their certificate every 2 months automatically. It means that I have to import the cert to our Java trust store manually every 2 months as well. Sometimes it caused production problems.

So, I made a method to solve it with SecureRestClientTrustManager to be able to consume https url without importing the cert file. Here is the method:

     public static String doPostSecureWithHeader(String url, String body, Map headers)
            throws Exception {
        log.info("start doPostSecureWithHeader " + url + " with param " + body);
        long startTime;
        long endTime;
        startTime = System.currentTimeMillis();
        Client client;
        client = Client.create();
        WebResource webResource;
        webResource = null;
        String output = null;
        try{
            SSLContext sslContext = null;
            SecureRestClientTrustManager secureRestClientTrustManager = new SecureRestClientTrustManager();
            sslContext = SSLContext.getInstance("SSL");
            sslContext
            .init(null,
                    new javax.net.ssl.TrustManager[] { secureRestClientTrustManager },
                    null);
            DefaultClientConfig defaultClientConfig = new DefaultClientConfig();
            defaultClientConfig
            .getProperties()
            .put(com.sun.jersey.client.urlconnection.HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
                    new com.sun.jersey.client.urlconnection.HTTPSProperties(
                            getHostnameVerifier(), sslContext));

            client = Client.create(defaultClientConfig);
            webResource = client.resource(url);

            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    webResource.setProperty(entry.getKey(), entry.getValue());
                }
            }
            WebResource.Builder builder =

                    builder.header(entry.getKey(), entry.getValue());
                }
            }

            ClientResponse response = builder
                    .post(ClientResponse.class, body);
            output = response.getEntity(String.class);
        }
        catch(Exception e){
            log.error(e.getMessage(),e);
            if(e.toString().contains("One or more of query value parameters are null")){
                output="-1";
            }
            if(e.toString().contains("401 Unauthorized")){
                throw e;

        }
        finally {
            if (client!= null) {
                client.destroy();

I faced this same issue on CentOS 7 years later

Posting hoping that it may help others...

Steps:

FIRST, configure the php-fpm settings:

-> systemctl stop php-fpm.service

-> cd /etc/php-fpm.d

-> ls -hal (should see a www.conf file)

-> cp www.conf www.conf.backup (back file up just in case)

-> vi www.conf

-> :/listen = (to get to the line we need to change)

-> i (to enter VI's text insertion mode)

-> change from listen = 127.0.0.1:9000 TO listen = /var/run/php-fpm/php-fpm.sock

-> Esc then :/listen.owner (to find it) then i (to change)

-> UNCOMMENT the listen.owner = nobody AND listen.group = nobody lines

-> Hit Esc then type :/user = then i

-> change user = apache TO user = nginx

-> AND change group = apache TO group = nginx

-> Hit Esc then :wq (to save and quit)

-> systemctl start php-fpm.service (now you will have a php-fpm.sock file)

SECOND, you configure your server {} block in your /etc/nginx/nginx.conf file. Then run:systemctl restart nginx.service

FINALLY, create a new .php file in your /usr/share/nginx/html directory for your Nginx server to serve up via the internet browser as a test.

-> vi /usr/share/nginx/html/mytest.php

-> type o

-> <?php echo date("Y/m/d-l"); ?> (PHP page will print date and day in browser)

-> Hit Esc

-> type :wq (to save and quite VI editor)

-> open up a browser and go to: http://yourDomainOrIPAddress/mytest.php (you should see the date and day printed)

I found the jQuery plugin jQuery Watermark to be better than the one listed in the top answer. Why better? Because it supports password input fields. Also, setting the color of the watermark (or other attributes) is as easy as creating a .watermark reference in your CSS file.

Following Query works for me. Database Tabel t_sonde_results has domain d_date (datatype DATE) and d_time (datatype TIME) The intention is to query for last entry in t_sonde_results sorted by Date and Time

select * from (select * from (SELECT * FROM t_sonde_results WHERE d_user_name = 'kenis' and d_smartbox_id = 6 order by d_time asc) AS tmp order by d_date and d_time limit 1) as tmp1

You can use an array and unpack it inside the select:

cols = ['_2','_4','_5']
df.select(*cols).show()

In common case you have private access for fields, so you CAN'T use getFields in reflection. Instead of this you should use getDeclaredFields

So, firstly, you should be aware if your Column annotation has the runtime retention:

@Retention(RetentionPolicy.RUNTIME)
@interface Column {
}

After that you can do something like this:

for (Field f: MyClass.class.getDeclaredFields()) {
   Column column = f.getAnnotation(Column.class);
       // ...
}

Obviously, you would like to do something with field - set new value using annotation value:

Column annotation = f.getAnnotation(Column.class);
if (annotation != null) {
    new PropertyDescriptor(f.getName(), Column.class).getWriteMethod().invoke(
        object,
        myCoolProcessing(
            annotation.value()
        )
    );
}

So, full code can be looked like this:

for (Field f : MyClass.class.getDeclaredFields()) {
    Column annotation = f.getAnnotation(Column.class);
    if (annotation != null)
        new PropertyDescriptor(f.getName(), Column.class).getWriteMethod().invoke(
                object,
                myCoolProcessing(
                        annotation.value()
                )
        );
}

I propose an alternative method using seaborn

Working code:

import pandas as pd
import seaborn as sns
data=np.random.rand(10,2)*100
df = pd.DataFrame(data, columns=['A', 'B'])
ax= sns.lineplot(data=df, markers= True)
ax.set(xlabel='xlabel', ylabel='ylabel', title='title')
#changing ylables ticks
y_value=['{:,.2f}'.format(x) + '%' for x in ax.get_yticks()]
ax.set_yticklabels(y_value)

What's new in .NET Framework 4 Client Profile RTM explains many of the differences:

When to use NET4 Client Profile and when to use NET4 Full Framework?
NET4 Client Profile:
Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).

NET4 Full framework:
Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes:

• If you are building Server apps. Such as:
  o ASP.Net apps
  o Server-side ASMX based web services
• If you use legacy client scenarios. Such as:
  o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.
  o Use legacy Windows Workflow Foundation 3.0 or 3.5 (WF3.0 , WF3.5)
• If you targeting developer scenarios and need tool such as MSBuild or need access to design assemblies such as System.Design.dll

However, as stated on MSDN, this is not relevant for >=4.5:

Starting with the .NET Framework 4.5, the Client Profile has been discontinued and only the full redistributable package is available. Optimizations provided by the .NET Framework 4.5, such as smaller download size and faster deployment, have eliminated the need for a separate deployment package. The single redistributable streamlines the installation process and simplifies your app's deployment options.

You can try this:

<div ng-app="app">
    <div ng-controller="AppCtrl">
        <a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
    </div>
</div>

<script>
var app = angular.module('app', []);

function AppCtrl($scope) {
        $scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
        $scope.fxn = function () {
            alert('It works');
        };
    }

app.directive("myDir", function ($compile) {
    return {
        scope: {ngClick: '='}
    };
});
</script>

The default element value of any array of primitives is already zero: false for booleans.

You start tomcat from some directory - which is the $cwd for tomcat. You can specify any path relative to this $cwd.

suppose you have

home
- tomcat
 |_bin
- cssStore
 |_file.css

And suppose you start tomcat from ~/tomcat, using the command "bin/startup.sh".

~/tomcat becomes the home directory ($cwd) for tomcat

You can access "../cssStore/file.css" from class files in your servlet now

Hope that helps, - M.S.

This is because the content of

<p myHighlight>Highlight me!</p>

has not been rendered when the constructor of the HighlightDirective is called so there is no content yet.

If you implement the AfterContentInit hook you will get the element and its content.

import { Directive, ElementRef, AfterContentInit } from '@angular/core';

@Directive({ selector: '[myHighlight]' })

export class HighlightDirective {

    constructor(private el: ElementRef) {
        //el.nativeElement.style.backgroundColor = 'yellow';
    }

    ngAfterContentInit(){
        //you can get to the element content here 
        //this.el.nativeElement
    }
}

@Michael Durrant's answer ably covers the shell itself, but the shell environment also includes the various commands you use in the shell and these are going to be similar -- but not identical -- between OS X and linux. In general, both will have the same core commands and features (especially those defined in the Posix standard), but a lot of extensions will be different.

For example, linux systems generally have a useradd command to create new users, but OS X doesn't. On OS X, you generally use the GUI to create users; if you need to create them from the command line, you use dscl (which linux doesn't have) to edit the user database (see here). (Update: starting in macOS High Sierra v10.13, you can use sysadminctl -addUser instead.)

Also, some commands they have in common will have different features and options. For example, linuxes generally include GNU sed, which uses the -r option to invoke extended regular expressions; on OS X, you'd use the -E option to get the same effect. Similarly, in linux you might use ls --color=auto to get colorized output; on macOS, the closest equivalent is ls -G.

EDIT: Another difference is that many linux commands allow options to be specified after their arguments (e.g. ls file1 file2 -l), while most OS X commands require options to come strictly first (ls -l file1 file2).

Finally, since the OS itself is different, some commands wind up behaving differently between the OSes. For example, on linux you'd probably use ifconfig to change your network configuration. On OS X, ifconfig will work (probably with slightly different syntax), but your changes are likely to be overwritten randomly by the system configuration daemon; instead you should edit the network preferences with networksetup, and then let the config daemon apply them to the live network state.

Uninstall whatever node version you have

sudo apt-get --purge remove node
sudo apt-get --purge remove nodejs-legacy
sudo apt-get --purge remove nodejs

install nvm (Node Version Manager) https://github.com/creationix/nvm

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh | bash

Now you can install whatever version of node you want and switch between the versions.

This is exactly what I needed for my MVC site configuration!

I added a little modification to the OnException method to handle multiple HandleErrorAttribute instances, as suggested by Atif Aziz:

bear in mind that you may have to take care that if multiple HandleErrorAttribute instances are in effect then duplicate logging does not occur.

I simply check context.ExceptionHandled before invoking the base class, just to know if someone else handled the exception before current handler.
It works for me and I post the code in case someone else needs it and to ask if anyone knows if I overlooked anything.

Hope it is useful:

public override void OnException(ExceptionContext context)
{
    bool exceptionHandledByPreviousHandler = context.ExceptionHandled;

    base.OnException(context);

    Exception e = context.Exception;
    if (exceptionHandledByPreviousHandler
        || !context.ExceptionHandled  // if unhandled, will be logged anyhow
        || RaiseErrorSignal(e)        // prefer signaling, if possible
        || IsFiltered(context))       // filtered?
        return;

    LogException(e);
}

To my knowledge these are the rules for calling subroutines and functions in VBScript:

• When calling a subroutine or a function where you discard the return value don't use parenthesis
• When calling a function where you assign or use the return value enclose the arguments in parenthesis
• When calling a subroutine using the Call keyword enclose the arguments in parenthesis

Since you probably wont be using the Call keyword you only need to learn the rule that if you call a function and want to assign or use the return value you need to enclose the arguments in parenthesis. Otherwise, don't use parenthesis.

Here are some examples:

• WScript.Echo 1, "two", 3.3 - calling a subroutine

• WScript.Echo(1, "two", 3.3) - syntax error

• Call WScript.Echo(1, "two", 3.3) - keyword Call requires parenthesis

• MsgBox "Error" - calling a function "like" a subroutine

• result = MsgBox("Continue?", 4) - calling a function where the return value is used

• WScript.Echo (1 + 2)*3, ("two"), (((3.3))) - calling a subroutine where the arguments are computed by expressions involving parenthesis (note that if you surround a variable by parenthesis in an argument list it changes the behavior from call by reference to call by value)

• WScript.Echo(1) - apparently this is a subroutine call using parenthesis but in reality the argument is simply the expression (1) and that is what tends to confuse people that are used to other programming languages where you have to specify parenthesis when calling subroutines

• I'm not sure how to interpret your example, Randomize(). Randomize is a subroutine that accepts a single optional argument but even if the subroutine didn't have any arguments it is acceptable to call it with an empty pair of parenthesis. It seems that the VBScript parser has a special rule for an empty argument list. However, my advice is to avoid this special construct and simply call any subroutine without using parenthesis.

I'm quite sure that these syntactic rules applies across different versions of operating systems.

You can use this (the French locale has , for decimal separator)

NumberFormat nf = NumberFormat.getInstance(Locale.FRANCE);
nf.parse(p);

Or you can use java.text.DecimalFormat and set the appropriate symbols:

DecimalFormat df = new DecimalFormat();
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setDecimalSeparator(',');
symbols.setGroupingSeparator(' ');
df.setDecimalFormatSymbols(symbols);
df.parse(p);

ReactJS is a JavaScript library, supporting both front-end web and being run on a server, for building user interfaces and web applications. It follows the concept of reusable components.

React Native is a mobile framework that makes use of the JavaScript engine available on the host, allowing you to build mobile applications for different platforms (iOS, Android, and Windows Mobile) in JavaScript that allows you to use ReactJS to build reusable components and communicate with native components further explanation

Both follow the JSX syntax extension of JavaScript. Which compiles to React.createElement calls under the hood. JSX in-depth

Both are open-sourced by Facebook.

Phonegap is pretty slow: clicking a button can take up to 3 sec to display the next screen. iscroll is slow and jumpy.

There other funny bugs and issues that i was able to overcome, but in total - not fully matured.

EDIT: Per Grumpy comment, it is not Phonegap who is actually slow, it is the JS/Browser native engine

In the latest version of Node.js (12.10.0 or later), the rmdir style functions fs.rmdir(), fs.rmdirSync(), and fs.promises.rmdir() have a new experimental option recursive that allows deleting non-empty directories, e.g.

fs.rmdir(path, { recursive: true });

You can then use that to change the size (or what ever else you want to do) at run time. Though as Arrow points out you can't set the Width and Height directly but have to set the Size property.

How to also send headers

Python 3:

import urllib.request
contents = urllib.request.urlopen(urllib.request.Request(
    "https://api.github.com/repos/cirosantilli/linux-kernel-module-cheat/releases/latest",
    headers={"Accept" : 'application/vnd.github.full+json"text/html'}
)).read()
print(contents)

Python 2:

import urllib2
contents = urllib2.urlopen(urllib2.Request(
    "https://api.github.com",
    headers={"Accept" : 'application/vnd.github.full+json"text/html'}
)).read()
print(contents)

For selected text use:

value: $('#dropDownId :selected').text();

For selected value use:

value: $('#dropDownId').val();

This worked for me:

Check the length property and use ? to avoid undefined errors.

So your example would be:

<div class="comeBack_up" *ngIf="previous_info?.length">

UPDATE

The length property only exists on arrays. Since the question was about objects, use Object.getOwnPropertyNames(obj) to get an array of properties from the object. The example becomes:

<div class="comeBack_up" *ngIf="previous_info  && Object.getOwnPropertyNames(previous_info).length > 0">

The previous_info && is added to check if the object exists. If it evaluates to true the next statement checks if the object has at least on proporty. It does not check whether the property has a value.

Building on what is mentioned in the comments, the simplest solution would be:

@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {

    //whatever

}

class SomeDto {

   private List<WhateverBudgerPerDateDTO> budgetPerDate;


  //getters setters
}

The solution assumes that the HTTP request you are creating actually has

Content-Type:application/json instead of text/plain

you can use download attribute to force download a file:

<a href="https://test.com/aaa.exe" download>click here to download</a>

Though you can do this through PHP's time functions, let me introduce you to PHP's DateTime class, which along with it's related classes, really should be in any PHP developer's toolkit.

// note this will set to today's current date since you are not specifying it in your passed parameter. This probably doesn't matter if you are just going to add time to it.
$datetime = DateTime::createFromFormat('g:i:s', $selectedTime);
$datetime->modify('+15 minutes');
echo $datetime->format('g:i:s');

Note that if what you are looking to do is basically provide a 12 or 24 hours clock functionality to which you can add/subtract time and don't actually care about the date, so you want to eliminate possible problems around daylights saving times changes an such I would recommend one of the following formats:

!g:i:s 12-hour format without leading zeroes on hour

!G:i:s 12-hour format with leading zeroes

Note the ! item in format. This would set date component to first day in Linux epoch (1-1-1970)

A tad more generic copy/paste function for your project.

sumjq = function(selector) {
    var sum = 0;
    $(selector).each(function() {
        sum += Number($(this).text());
    });
    return sum;
}

console.log(sumjq('.price'));

For Eclipse Kepler, there is no Help > About Eclipse but I found this works:

Eclipse > About Eclipse

There are two ways to achieve that:

• Use -rpath linker option:

gcc XXX.c -o xxx.out -L$HOME/.usr/lib -lXX -Wl,-rpath=/home/user/.usr/lib

• Use LD_LIBRARY_PATH environment variable - put this line in your ~/.bashrc file:

  export LD_LIBRARY_PATH=/home/user/.usr/lib

This will work even for a pre-generated binaries, so you can for example download some packages from the debian.org, unpack the binaries and shared libraries into your home directory, and launch them without recompiling.

For a quick test, you can also do (in bash at least):

LD_LIBRARY_PATH=/home/user/.usr/lib ./xxx.out

which has the advantage of not changing your library path for everything else.

In case one wants to create FK constraints from UAT environment table to Live, fire below dynamic query.....

    SELECT 'ALTER TABLE '||OBJ.NAME||' ADD CONSTRAINT '||CONST.NAME||'     FOREIGN KEY ('||COALESCE(ACOL.NAME, COL.NAME)||') REFERENCES '

Check your windows-firewall feature in control panel. Outbound and inbound port should allow port 8089. (or write a new rule for this- Right hand side, actions - new rules.) it worked for me!

You can't store "no character" in a character - it doesn't make sense.

As an alternative you could store a character that has a special meaning to you - e.g. null char '\0' - and treat this specially.

$.getJSON is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.

Alternatively you could use jQuery's $.when/.then(), similar to this:

var input = "netuetamundis";  var sID;  $(document).ready(function () {     $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () {         obj = name;         sID = obj.id;         console.log(sID);     })).then(function () {         $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) {             console.log(stats);         });     }); }); 

This would be more open for future modification and separates out the responsibility for the first call to know about the second call.

The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.

Here is another similar option. In my case, I'm checking values in another box as I build a select list. I kept running into undefined values when I would compare, so I set my check this way:

if ( $("#select-box option[value='" + thevalue + "']").val() === undefined) { //do stuff }

I've no idea if this approach is more expensive.

Try this code:

AlertDialog.Builder builder1 = new AlertDialog.Builder(context);
builder1.setMessage("Write your message here.");
builder1.setCancelable(true);

builder1.setPositiveButton(
    "Yes",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
        }
    });

builder1.setNegativeButton(
    "No",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
        }
    });

AlertDialog alert11 = builder1.create();
alert11.show();

Accepted answer didn't work for PostgreSQL (syntax error at or near "a").

The way you do this in PostgreSQL is by using generate_series function, i.e.:

SELECT day::date
FROM generate_series('2010-01-20', '2010-01-24', INTERVAL '1 day') day;

    day
------------
 2010-01-20
 2010-01-21
 2010-01-22
 2010-01-23
 2010-01-24
(5 rows)

Another approach is by using FormBody.Builder().
Here's an example of callback:

Callback loginCallback = new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        try {
            Log.i(TAG, "login failed: " + call.execute().code());
        } catch (IOException e1) {
            e1.printStackTrace();
        }
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        // String loginResponseString = response.body().string();
        try {
            JSONObject responseObj = new JSONObject(response.body().string());
            Log.i(TAG, "responseObj: " + responseObj);
        } catch (JSONException e) {
            e.printStackTrace();
        }
        // Log.i(TAG, "loginResponseString: " + loginResponseString);
    }
};

Then, we create our own body:

RequestBody formBody = new FormBody.Builder()
        .add("username", userName)
        .add("password", password)
        .add("customCredential", "")
        .add("isPersistent", "true")
        .add("setCookie", "true")
        .build();

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(this)
        .build();
Request request = new Request.Builder()
        .url(loginUrl)
        .post(formBody)
        .build();

Finally, we call the server:

client.newCall(request).enqueue(loginCallback);

Honestly, this is the sort of situation where I just open up Python on the command line and start messing around:

 >>> x = "Dana Larose is playing with find()"
 >>> x.find("Dana")
 0
 >>> x.find("ana")
 1
 >>> x.find("La")
 5
 >>> x.find("La", 6)
 -1

Python's interpreter makes this sort of experimentation easy. (Same goes for other languages with a similar interpreter)

    ...
    gradle.taskGraph.beforeTask { Task task ->
        if (task.name ==~ /process.*GoogleServices/) {
            android.applicationVariants.all { variant ->
                if (task.name ==~ /(?i)process${variant.flavorName}(Debug|Release)GoogleServices/) {
                    copy {
                        from "src/tenants/${variant.flavorName}"
                        include 'google-services.json'
                        into '.'
                    }
                }
            }
        }
    }

    gradle.taskGraph.afterTask { Task task ->
        if (task.name ==~ /process.*GoogleServices/) {
            android.applicationVariants.all { variant ->
                if (task.name ==~ /(?i)process${variant.flavorName}(Debug|Release)GoogleServices/) {
                    delete fileTree(".").matching {
                        include 'google-services.json'
                    }
                }
            }
        }
    }

From this paper: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2049.pdf

for( type-speci?er-seq simple-declarator : expression ) statement

is syntactically equivalent to

{
    typedef decltype(expression) C;
    auto&& rng(expression);
    for (auto begin(std::For<C>::begin(rng)), end(std::For<C>::end(rng)); begin != end; ++ begin) {
        type-speci?er-seq simple-declarator(*begin);
        statement
    }
}

So you can clearly see that what is abc in your case will be std::pair<key_type, value_type >. So for printing you can do access each element by abc.first and abc.second

Using svcutil, you can create interfaces and classes (data contracts) from the WSDL.

svcutil your.wsdl (or svcutil your.wsdl /l:vb if you want Visual Basic)

This will create a file called "your.cs" in C# (or "your.vb" in VB.NET) which contains all the necessary items.

Now, you need to create a class "MyService" which will implement the service interface (IServiceInterface) - or the several service interfaces - and this is your server instance.

Now a class by itself doesn't really help yet - you'll need to host the service somewhere. You need to either create your own ServiceHost instance which hosts the service, configure endpoints and so forth - or you can host your service inside IIS.

CSS way:

#foo {
   position: absolute;
   top: 0;
   right: 0;
   bottom: 0;
   left: 0;
}

JS way:

$(function() {
    function abso() {
        $('#foo').css({
            position: 'absolute',
            width: $(window).width(),
            height: $(window).height()
        });
    }

    $(window).resize(function() {
        abso();         
    });

    abso();
});

Enumeration(?):

Enumeration e = new Vector(set).elements();
while (e.hasMoreElements())
    {
        System.out.println(e.nextElement());
    }

Another way (java.util.Collections.enumeration()):

for (Enumeration e1 = Collections.enumeration(set); e1.hasMoreElements();)
    {
        System.out.println(e1.nextElement());
    }

Java 8:

set.forEach(element -> System.out.println(element));

or

set.stream().forEach((elem) -> {
    System.out.println(elem);
});

#include<stdio.h>
int main()
{
    int a,b,i,c,j;
    printf("\n Enter the two no. in between you want to check:");
    scanf("%d%d",&a,&c);
    printf("%d-%d\n",a,c);
    for(j=a;j<=c;j++)
    {
        b=0;
        for(i=1;i<=c;i++)
        {
            if(j%i==0)
            {
                 b++;
            }
        }
        if(b==2)
        {
            printf("\nPrime number:%d\n",j);
        }
        else
        {
            printf("\n\tNot prime:%d\n",j);
        }
    }
}

I'm using Angular 6. I followed Mav55's answer and it worked. However I wanted to make sure if fixture.detectChanges(); was really necessary so I removed it and it still worked. Then I removed tick(); to see if it worked and it did. Finally I removed the test from the fakeAsync() wrap, and surprise, it worked.

So I ended up with this:

it('should call onClick method', () => {
  const onClickMock = spyOn(component, 'onClick');
  fixture.debugElement.query(By.css('button')).triggerEventHandler('click', null);
  expect(onClickMock).toHaveBeenCalled();
});

And it worked just fine.

Apparently (as you point in the error log), after updating to Angular 6.0.0 rxjs-compat is missing.

Run npm install rxjs-compat --save to install. Should fix it.

Unless you are really concerned with performance, and by that I mean, "Why are you using .Net instead of C++?" you should stick with List<>. It's easier to maintain and does all the dirty work of resizing an array behind the scenes for you. (If necessary, List<> is pretty smart about choosing array sizes so it doesn't need to usually.)

Try to use GMT instead of UTC. They refer to the same time zone, yet the name GMT is more common and might work.

I think, recursion isn't the best way to solve this problem, but one recursive way I see here is shown below:

String str = prepareString(originalString); //make upper case, remove some characters 
isPalindrome(str);

public boolean isPalindrome(String str) {
   return str.length() == 1 || isPalindrome(str, 0);
}

private boolean isPalindrome(String str, int i) {
       if (i > str.length / 2) {
      return true;
   }
   if (!str.charAt(i).equals(str.charAt(str.length() - 1 - i))) {
      return false;
   }
   return isPalindrome(str, i+1);
}

For varchars, you may need to do something like this:

select convert(varchar(25), NULL) as abc_column into xyz_table

If you try

select '' as abc_column into xyz_table

you may get errors related to truncation, or an issue with null values, once you populate.

I use the following:

UIView *view = [[UIView alloc] init];
myTableView.tableFooterView = view;
[view release];

Doing it in viewDidLoad. But you can set it anywhere.

A complete beginner like myself to the topic may find it harder to implement one of these answers than, if within your control, to resize the image yourself with an online editor or a photo editor like Photoshop.

Regex object is thread-safe for Matching functions. Knowing that and there are some performance options or cultural / language issues, I propose this simple solution.

public static Regex _regex = new Regex(
    @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
    RegexOptions.CultureInvariant | RegexOptions.Singleline);

public static bool IsValidEmailFormat(string emailInput)
{
    return _regex.IsMatch(emailInput);
}

Alternative Configuration for Regex:

public static Regex _regex = new Regex(
    @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
    RegexOptions.CultureInvariant | RegexOptions.Compiled);

I find that compiled is only faster on big string matches, like book parsing for example. Simple email matching is faster just letting Regex interpret.

IE has a setting, located in Tools / Internet options / Advanced / Browsing, called Reuse windows for launching shortcuts, which is checked by default. For IE versions that support tabbed browsing, this option is relevant only when tab browsing is turned off (in fact, IE9 Beta explicitly mentions this). However, since IE6 does not have tabbed browsing, this option does affect opening URLs through the shell (as in your example).

One more example with pytz, but includes localize(), which saved my day.

import pytz, datetime
utc = pytz.utc
fmt = '%Y-%m-%d %H:%M:%S'
amsterdam = pytz.timezone('Europe/Amsterdam')

dt = datetime.datetime.strptime("2012-04-06 10:00:00", fmt)
am_dt = amsterdam.localize(dt)
print am_dt.astimezone(utc).strftime(fmt)
'2012-04-06 08:00:00'

Sorting an observable and returning the same object sorted can be done using an extension method. For larger collections watch out for the number of collection changed notifications.

I have updated my code to improve performance (thanks to nawfal) and to handle duplicates which no other answers here do at time of writing. The observable is partitioned into a left sorted half and a right unsorted half, where each time the minimum item (as found in the sorted list) is shifted to the end of the sorted partition from the unsorted. Worst case O(n). Essentially a selection sort (See below for output).

public static void Sort<T>(this ObservableCollection<T> collection)
        where T : IComparable<T>, IEquatable<T>
    {
        List<T> sorted = collection.OrderBy(x => x).ToList();

        int ptr = 0;
        while (ptr < sorted.Count - 1)
        {
            if (!collection[ptr].Equals(sorted[ptr]))
            {
                int idx = search(collection, ptr+1, sorted[ptr]);
                collection.Move(idx, ptr);
            }
            
            ptr++;
        }
    }

    public static int search<T>(ObservableCollection<T> collection, int startIndex, T other)
            {
                for (int i = startIndex; i < collection.Count; i++)
                {
                    if (other.Equals(collection[i]))
                        return i;
                }
    
                return -1; // decide how to handle error case
            }

usage: Sample with an observer (used a Person class to keep it simple)

    public class Person:IComparable<Person>,IEquatable<Person>
            { 
                public string Name { get; set; }
                public int Age { get; set; }
    
                public int CompareTo(Person other)
                {
                    if (this.Age == other.Age) return 0;
                    return this.Age.CompareTo(other.Age);
                }
    
                public override string ToString()
                {
                    return Name + " aged " + Age;
                }
    
                public bool Equals(Person other)
                {
                    if (this.Name.Equals(other.Name) && this.Age.Equals(other.Age)) return true;
                    return false;
                }
            }
    
          static void Main(string[] args)
            {
                Console.WriteLine("adding items...");
                var observable = new ObservableCollection<Person>()
                {
                    new Person {Name = "Katy", Age = 51},
                    new Person {Name = "Jack", Age = 12},

Jack aged 12 move from 2 to 1
5,(12),51,13,39,14,41,20,39,19,
Bob aged 13 move from 3 to 2

The Person class implements both IComparable and IEquatable the latter is used to minimise the changes to the collection so as to reduce the number of change notifications raised

• EDIT Sorts same collection without creating a new copy *

To return an ObservableCollection, call .ToObservableCollection on *sortedOC* using e.g. [this implementation][1].

**** orig answer - this creates a new collection **** You can use linq as the doSort method below illustrates. A quick code snippet: produces

3:xey 6:fty 7:aaa

Alternatively you could use an extension method on the collection itself

var sortedOC = _collection.OrderBy(i => i.Key);

private void doSort()
{
    ObservableCollection<Pair<ushort, string>> _collection = 
        new ObservableCollection<Pair<ushort, string>>();

    _collection.Add(new Pair<ushort,string>(7,"aaa"));
    _collection.Add(new Pair<ushort, string>(3, "xey"));
    _collection.Add(new Pair<ushort, string>(6, "fty"));

    var sortedOC = from item in _collection
                   orderby item.Key
                   select item;

    foreach (var i in sortedOC)
    {
        Debug.WriteLine(i);
    }

}

public class Pair<TKey, TValue>
{
    private TKey _key;

    public TKey Key
    {
        get { return _key; }
        set { _key = value; }
    }
    private TValue _value;

    public TValue Value
    {
        get { return _value; }
        set { _value = value; }
    }
    
    public Pair(TKey key, TValue value)
    {
        _key = key;
        _value = value;

    }

    public override string ToString()
    {
        return this.Key + ":" + this.Value;
    }
}

In a shameless attempt to steal some votes, SecurityProtocol is an Enum with the [Flags] attribute. So you can do this:

[Net.ServicePointManager]::SecurityProtocol = 
  [Net.SecurityProtocolType]::Tls12 -bor `
  [Net.SecurityProtocolType]::Tls11 -bor `
  [Net.SecurityProtocolType]::Tls

Or since this is PowerShell, you can let it parse a string for you:

[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"

Then you don't technically need to know the TLS version.

I copied and pasted this from a script I created after reading this answer because I didn't want to cycle through all the available protocols to find one that worked. Of course, you could do that if you wanted to.

Final note - I have the original (minus SO edits) statement in my PowerShell profile so it's in every session I start now. It's not totally foolproof since there are still some sites that just fail but I surely see the message in question much less frequently.

What worked for me is to add include tag in order to specify exactly what I want to filter.

It seems the resource plugin has problems going through the whole src/main/resource folder, probably due to some specific files inside.

    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>application.yml</include>
            </includes>
        </resource>
    </resources>

With the class below you can make the suggestion of Donut "exception safe".

using (new CursorHandler())
{
    // Execute your time-intensive hashing code here...
}

the class CursorHandler

public class CursorHandler
    : IDisposable
{
    public CursorHandler(Cursor cursor = null)
    {
        _saved = Cursor.Current;
        Cursor.Current = cursor ?? Cursors.WaitCursor;
    }

    public void Dispose()
    {
        if (_saved != null)
        {
            Cursor.Current = _saved;
            _saved = null;
        }
    }

    private Cursor _saved;
}

1. Put your cursor at the begining of line 1.
2. click Edit>ColumnEditor. Put " in the text and hit enter.
3. Repeat 2 but put the cursor at the end of line1 and put ", and hit enter.

Bombe's answer is correct, however note that unless you absolutely must use MD5 (e.g. forced on you for interoperability), a better choice is SHA1 as MD5 has weaknesses for long term use.

I should add that SHA1 also has theoretical vulnerabilities, but not as severe. The current state of the art in hashing is that there are a number of candidate replacement hash functions but none have yet emerged as the standard best practice to replace SHA1. So, depending on your needs you would be well advised to make your hash algorithm configurable so it can be replaced in future.

From AWS S3 Docs (How do I use folders in an S3 bucket?):

In Amazon S3, buckets and objects are the primary resources, and objects are stored in buckets. Amazon S3 has a flat structure instead of a hierarchy like you would see in a file system. However, for the sake of organizational simplicity, the Amazon S3 console supports the folder concept as a means of grouping objects. Amazon S3 does this by using a shared name prefix for objects (that is, objects have names that begin with a common string). Object names are also referred to as key names.

For example, you can create a folder on the console named photos and store an object named myphoto.jpg in it. The object is then stored with the key name photos/myphoto.jpg, where photos/ is the prefix.

To download all files from "mybucket" into the current directory respecting the bucket's emulated directory structure (creating the folders from the bucket if they don't already exist locally):

import boto3
import os

bucket_name = "mybucket"
s3 = boto3.client("s3")
objects = s3.list_objects(Bucket = bucket_name)["Contents"]
for s3_object in objects:
    s3_key = s3_object["Key"]
    path, filename = os.path.split(s3_key)
    if len(path) != 0 and not os.path.exists(path):
        os.makedirs(path)
    if not s3_key.endswith("/"):
        download_to = path + '/' + filename if path else filename
        s3.download_file(bucket_name, s3_key, download_to)

Use PerfMon to collect data and DebugDiag to analyse.

Not as bulletproof as the above answer, however still effective:

#!/bin/bash
if [ "$1" = "" ]
then
  echo "Usage: $0 <id number to be cleaned up>"
  exit
fi

# rm commands go here

The selector would be #demolist.dropdown-menu li a note no space between id and class. However i would suggest a more generic approach:

<div class="input-group">                                            
    <input type="TextBox" Class="form-control datebox"></input>
    <div class="input-group-btn">
    <button type="button" class="btn dropdown-toggle" data-toggle="dropdown">
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
        <li><a href="#">A</a></li>
        <li><a href="#">B</a></li>
        <li><a href="#">C</a></li>
    </ul>
</div>


$(document).on('click', '.dropdown-menu li a', function() {
    $(this).parent().parent().parent().find('.datebox').val($(this).html());
}); 

by using a class rather than id, and using parent().find(), you can have as many of these on a page as you like, with no duplicated js

This will work. Link to your SVG using the following pattern:

https://cdn.rawgit.com/<repo-owner>/<repo>/<branch>/path/to.svg

The downside is hardcoding the owner and repo in the path, meaning the svg will break if either of those are renamed.

    function validateform()
    {
     if (trimAll(document.getElementById("<%=txtFromDate.ClientID %>").value) != "") {
   if (!isDate(trimAll(document.getElementById("<%=txtFromDate.ClientID %>").value)))
         msg = msg + "<li>Please enter valid From Date in mm/dd/yyyy format\n";
   else {
       var toDate = new Date();
       var txtdate = document.getElementById("<%=txtFromDate.ClientID %>").value;
       var d1 = new Date(txtdate)
   if (Date.parse(txtdate) > Date.parse(toDate)) {                   
         msg = msg + "<li>From date must be less than or equal to today's date\n";
   }
  }
}

     if (trimAll(document.getElementById("<%=txtToDate.ClientID %>").value) != "") {
            if (!isDate(trimAll(document.getElementById("<%=txtToDate.ClientID %>").value)))
                msg = msg + "<li>Please enter valid To Date in mm/dd/yyyy format\n";
            else {
                var toDate = new Date();
                var txtdate = document.getElementById("<%=txtToDate.ClientID %>").value;
                var d1 = new Date(txtdate)

                if (Date.parse(txtdate) > Date.parse(toDate)) {
                    msg = msg + "<li>To date must be less than or equal to today's date\n"; 
                  }
                 }
                }

Considering what Damith posted, I like to think you can just qualify active by the Viewbag.Title (best practice is to populate this in your content pages allowing your _Layout.cshtml page to hold your link bars). Also note that if you are using sub-menu items it also works fine:

<li class="has-sub @(ViewBag.Title == "Dashboard 1" || ViewBag.Title == "Dashboard 2" ? "active" : "" )">
    <a href="javascript:;">
        <b class="caret"></b>
        <i class="fa fa-th-large"></i>
        <span>Dashboard</span>
    </a>
    <ul class="sub-menu">
        <li class="@(ViewBag.Title == "Dashboard 1" ? "active" : "")"><a href="index.html">Dashboard v1</a></li>
        <li class="@(ViewBag.Title == "Dashboard 2" ? "active" : "")"><a href="index_v2.html">Dashboard v2</a></li>
    </ul>
</li>

Your code doesn't do what you might think it does. Async methods return immediately after the method begins waiting for the async result. It's insightful to use tracing in order to investigate how the code is actually behaving.

The code below does the following:

• Create 4 tasks
• Each task will asynchronously increment a number and return the incremented number
• When the async result has arrived it is traced.

static TypeHashes _type = new TypeHashes(typeof(Program));        
private void Run()
{
    TracerConfig.Reset("debugoutput");

    using (Tracer t = new Tracer(_type, "Run"))
    {
        for (int i = 0; i < 4; i++)
        {
            DoSomeThingAsync(i);
        }
    }
    Application.Run();  // Start window message pump to prevent termination
}


private async void DoSomeThingAsync(int i)
{
    using (Tracer t = new Tracer(_type, "DoSomeThingAsync"))
    {
        t.Info("Hi in DoSomething {0}",i);
        try
        {
            int result = await Calculate(i);
            t.Info("Got async result: {0}", result);
        }
        catch (ArgumentException ex)
        {
            t.Error("Got argument exception: {0}", ex);
        }
    }
}

Task<int> Calculate(int i)
{
    var t = new Task<int>(() =>
    {
        using (Tracer t2 = new Tracer(_type, "Calculate"))
        {
            if( i % 2 == 0 )
                throw new ArgumentException(String.Format("Even argument {0}", i));
            return i++;
        }
    });
    t.Start();
    return t;
}

You will notice that the Run method completes on thread 2820 while only one child thread has finished (2756). If you put a try/catch around your await method you can "catch" the exception in the usual way although your code is executed on another thread when the calculation task has finished and your contiuation is executed.

The calculation method traces the thrown exception automatically because I did use the ApiChange.Api.dll from the ApiChange tool. Tracing and Reflector helps a lot to understand what is going on. To get rid of threading you can create your own versions of GetAwaiter BeginAwait and EndAwait and wrap not a task but e.g. a Lazy and trace inside your own extension methods. Then you will get much better understanding what the compiler and what the TPL does.

Now you see that there is no way to get in a try/catch your exception back since there is no stack frame left for any exception to propagate from. Your code might be doing something totally different after you did initiate the async operations. It might call Thread.Sleep or even terminate. As long as there is one foreground thread left your application will happily continue to execute asynchronous tasks.

You can handle the exception inside the async method after your asynchronous operation did finish and call back into the UI thread. The recommended way to do this is with TaskScheduler.FromSynchronizationContext. That does only work if you have an UI thread and it is not very busy with other things.

Setting the launcher icons like a native developer

I was having some trouble using and understanding the flutter_launcher_icons package. This answer is how you would do it if you were creating an app for Android or iOS natively. It is pretty fast and easy once you have done it a few times.

Android

Android launcher icons have both a foreground and a background layer.

(image adapted from Android documentation)

The easiest way to create launcher icons for Android is to use the Asset Studio that is available right in Android Studio. You don't even have to leave your Flutter project. (VS Code users, you might consider using Android Studio just for this step. It's really very convenient and it doesn't hurt to be familiar with another IDE.)

Right click on the android folder in the project outline. Go to New > Image Asset. (Try right clicking the android/app folder if you don't see Image Asset as an option. Also see the comments below for more suggestions.) Now you can select an image to create your launcher icon from.

Note: I usually use a 1024x1024 pixel image but you should certainly use nothing smaller that 512x512. If you are using Gimp or Inkscape, you should have two layers, one for the foreground and one for the background. The foreground image should have transparent areas for the background layer to show through.

(lion clipart from here)

This will replace the current launcher icons. You can find the generated icons in the mipmap folders:

If you would prefer to create the launcher icons manually, see this answer for help.

Finally, make sure that the launcher icon name in the AndroidManifest is the same as what you called it above (ic_launcher by default):

application android:icon="@mipmap/ic_launcher"

Run the app in the emulator to confirm that the launcher icon was created successfully.

iOS

I always used to individually resize my iOS icons by hand, but if you have a Mac, there is a free app in the Mac App Store called Icon Set Creator. You give it an image (of at least 1024x1024 pixels) and it will spit out all the sizes that you need (plus the Contents.json file). Thanks to this answer for the suggestion.

iOS icons should not have any transparency. See more guidelines here.

After you have created the icon set, start Xcode (assuming you have a Mac) and use it to open the ios folder in your Flutter project. Then go to Runner > Assets.xcassets and delete the AppIcon item.

After that right-click and choose Import.... Choose the icon set that you just created.

That's it. Confirm that the icon was created by running the app in the simulator.

If you don't have a Mac...

You can still create all of the images by hand. In your Flutter project go to ios/Runner/Assets.xcassets/AppIcon.appiconset.

The image sizes that you need are the multiplied sizes in the filename. For example, [email protected] would be 29 times 3, that is, 87 pixels square. You either need to keep the same icon names or edit the JSON file.

One simple way to do this is :
Go to Preferences -> Package Settings -> Your Theme Name -> Activation

In my case I installed Boxy Theme so the path will be
Preferences -> Package Settings -> Boxy Theme -> Activation

Then there will be a pop-up menu that will let you choose which type of the theme package you want to activate.
Use up and down arrow so choose then press enter or simply click the one you want to choose.

This is steps only applicable if the theme installed also customized the sublime text 3 sidebar.

Hope it help anyone!

You can use /start /max [your batch] it will fill the screen with the program it oppose to /min

You can use logger.exception("msg") for logging exception with traceback:

try:
    #your code
except Exception as e:
    logger.exception('Failed: ' + str(e))

CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(1);

See Here for more details.

Or

DateTime dt = DateTime.Now;
Console.WriteLine( dt.ToString( "MMMM" ) );

Or if you want to get the culture-specific abbreviated name.

GetAbbreviatedMonthName(1);

This solution works for matplotlib versions 3.0.1, 3.0.3 and 3.2.1.

def save_inp_as_output(_img, c_name, dpi=100):
    h, w, _ = _img.shape
    fig, axes = plt.subplots(figsize=(h/dpi, w/dpi))
    fig.subplots_adjust(top=1.0, bottom=0, right=1.0, left=0, hspace=0, wspace=0) 
    axes.imshow(_img)
    axes.axis('off')
    plt.savefig(c_name, dpi=dpi, format='jpeg') 

Because the subplots_adjust setting makes the axis fill the figure, you don't want to specify a bbox_inches='tight', as it actually creates whitespace padding in this case. This solution works when you have more than 1 subplot also.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

I spent some time on the two main approaches here and they didn't work-out for me. I am using Netbeans for the builds, may be there's more going on there. I had some errors and warnings from Maven 3 with some constructs, but I think those were easy to correct. No biggie.

I did find an answer that looks maintainable and simple to implement in this article on DZone:

• Stamping Version Number and Build Time in a Properties File with Maven

I already have a resources/config sub-folder, and I named my file: app.properties, to better reflect the kind of stuff we may keep there (like a support URL, etc.).

The only caveat is that Netbeans gives a warning that the IDE needs filtering off. Not sure where/how. It has no effect at this point. Perhaps there's a work around for that if I need to cross that bridge. Best of luck.

Another option:

UPDATE `table` SET the_col = current_timestamp

Looks odd, but works as expected. If I had to guess, I'd wager this is slightly faster than calling now().

AFAIK all you can do is omit the returns to make things more compact in C++:

switch(Answer)
{
    case 1: case 2: case 3: case 4:
        cout << "You need more cars.";
        break;
    ...
}

(You could remove the other returns as well, of course.)

Using unique():

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))    
dat[row.names(unique(dat[,c("id", "id2")])),]

I found we need to use noConflict sometimes:

jQuery.noConflict()(function ($) { // this was missing for me
    $(document).ready(function() { 

       other code here....

    });
});

From the docs:

Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. If you need to use another JavaScript library alongside jQuery, return control of $ back to the other library with a call to $.noConflict(). Old references of $ are saved during jQuery initialization; noConflict() simply restores them.

ob_start();  // turns on output buffering
$foo->bar();  // all output goes only to buffer
ob_clean();  // delete the contents of the buffer, but remains buffering active
$foo->render(); // output goes to buffer
ob_flush(); // send buffer output
$none = ob_get_contents();  // buffer content is now an empty string
ob_end_clean();  // turn off output buffering

Buffers can be nested, so while one buffer is active, another ob_start() activates a new buffer. So ob_end_flush() and ob_flush() are not really sending the buffer to the output, but to the parent buffer. And only when there is no parent buffer, contents is sent to browser or terminal.

Nicely explained here: https://phpfashion.com/everything-about-output-buffering-in-php

Shift-Alt-J is a useful keyboard shortcut in Eclipse for creating Javadoc comment templates.

Invoking the shortcut on a class, method or field declaration will create a Javadoc template:

public int doAction(int i) {
    return i;
}

Pressing Shift-Alt-J on the method declaration gives:

/**
 * @param i
 * @return
 */
public int doAction(int i) {
    return i;
}

Checking the header file solve's the problem. One can check for there system compiler.

For my system , AF_INET == PF_INET

AF == Address Family And PF == Protocol Family

Protocol families, same as address families.

Use the properties-maven-plugin to write specific pom properties to a file at compile time, and then read that file at run time.

In your pom.xml:

<properties>
     <name>${project.name}</name>
     <version>${project.version}</version>
     <foo>bar</foo>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>properties-maven-plugin</artifactId>
            <version>1.0.0</version>
            <executions>
                <execution>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>write-project-properties</goal>
                    </goals>
                    <configuration>
                        <outputFile>${project.build.outputDirectory}/my.properties</outputFile>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

And then in .java:

java.io.InputStream is = this.getClass().getResourceAsStream("my.properties");
java.util.Properties p = new Properties();
p.load(is);
String name = p.getProperty("name");
String version = p.getProperty("version");
String foo = p.getProperty("foo");

My problem wasn't that the connection string I was providing was wrong, or that the connection string in the app.config I thought I was using was wrong, but that I was using the wrong app.config.

To stop a service, you have to find service name using:

adb shell dumpsys activity services <your package>

for example: adb shell dumpsys activity services com.xyz.something

This will list services running for your package.
Output should be similar to:

ServiceRecord{xxxxx u0 com.xyz.something.beta/xyz.something.abc.XYZService}

Now select your service and run:

adb shell am stopservice <service_name> 

For example:

adb shell am stopservice com.xyz.something.beta/xyz.something.abc.XYZService

similarly, to start service:

adb shell am startservice <service_name>

To access service, your service(in AndroidManifest.xml) should set exported="true"

<!-- Service declared in manifest -->
<service
    android:name=".YourServiceName"
    android:exported="true"
    android:launchMode="singleTop">
    <intent-filter>
        <action android:name="com.your.package.name.YourServiceName"/>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</service>

same browsers may return string for border width, in this parseInt will return NaN so make sure you parse value to int properly.

        var getInt = function (string) {
            if (typeof string == "undefined" || string == "")
                return 0;
            var tempInt = parseInt(string);

            if (!(tempInt <= 0 || tempInt > 0))
                return 0;
            return tempInt;
        }

        var liWidth = $(this).width();
        liWidth += getInt($(this).css("padding-left"));
        liWidth += getInt($(this).css("padding-right"));
        liWidth += getInt($(this).css("border-left-width"));
        liWidth += getInt($(this).css("border-right-width"));

600851475143 cannot be represented as a 32-bit integer (type int). It can be represented as a 64-bit integer (type long). long literals in Java end with an "L": 600851475143L

The t indicates text mode, meaning that \n characters will be translated to the host OS line endings when writing to a file, and back again when reading. The flag is basically just noise, since text mode is the default.

Other than U, those mode flags come directly from the standard C library's fopen() function, a fact that is documented in the sixth paragraph of the python2 documentation for open().

As far as I know, t is not and has never been part of the C standard, so although many implementations of the C library accept it anyway, there's no guarantee that they all will, and therefore no guarantee that it will work on every build of python. That explains why the python2 docs didn't list it, and why it generally worked anyway. The python3 docs make it official.
