You could use QueryToDoc (http://www.querytodoc.com). It lets you write a query against a SQL database and export the results - after you pick the delimiter - to Excel, Word, HTML, or CSV

I think you are trying to run an emulator based on x86. I got the same error when I just download the HAXM under Extras category of Android SDK Manager. Actually, you need install it. Go to the directory of extras and run the installation of HAXM. Hope this will solve your problem.

So I'm not entirely sure why this works, but it saves an image with my plot:

dtf = pd.DataFrame.from_records(d,columns=h)
dtf2.plot()
fig = plt.gcf()
fig.savefig('output.png')

I'm guessing that the last snippet from my original post saved blank because the figure was never getting the axes generated by pandas. With the above code, the figure object is returned from some magic global state by the gcf() call (get current figure), which automagically bakes in axes plotted in the line above.

To update TechDo's answer for SQL server 2012. You need to change: 'FROM ' + @TableName + ' (NOLOCK) ' to FROM ' + @TableName + 'WITH (NOLOCK) ' +

Other wise you will get the following error: Deprecated feature 'Table hint without WITH' is not supported in this version of SQL Server.

Below is the complete updated stored procedure:

CREATE PROC SearchAllTables

@SearchStr nvarchar(100)
)

BEGIN

    CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

    WHILE @TableName IS NOT NULL

    BEGIN

I don't know how good of a solution this is it, but after following some of the other answer to this question without success, i resolved setting the connection user of the service MSSQLSERVER to "Local Service".

N.B: i'm using SQL Server 2017.

I work for a market research company and we have to filter these types of input alllll the time. You're complicating it too much. Just strip the non-alphanumeric chars, and see if there's an extension.

For further analysis you can subscribe to one of many providers that will give you access to a database of valid numbers as well as tell you if they're landlines or mobiles, disconnected, etc. It costs money.

Turns out for me that SET NOCOUNT ON was set in the stored procedure script (by default on SQL Server Management Studio) and SqlCommand.ExecuteNonQuery(); always returned -1.

I just set it off: SET NOCOUNT OFF without needing to use @@ROWCOUNT.

More details found here : SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

First, check if you have internet permission in Manifest file.

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

You can then add following code in onCreate() or initialize() method-

final WebView webview = (WebView) rootView.findViewById(R.id.webview);
        webview.setWebViewClient(new MyWebViewClient());
        webview.getSettings().setBuiltInZoomControls(false);
        webview.getSettings().setSupportZoom(false);
        webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        webview.getSettings().setAllowFileAccess(true);
        webview.getSettings().setDomStorageEnabled(true);
        webview.loadUrl(URL);

And write a class to handle callbacks of webview -

public class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                           //your handling...
                return super.shouldOverrideUrlLoading(view, url);
        }
    }

in same class, you can also use other important callbacks such as -

- onPageStarted()
- onPageFinished()
- onReceivedSslError()

Also, you can add "SwipeRefreshLayout" to enable swipe refresh and refresh the webview.

<android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipeRefreshLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <WebView
            android:id="@+id/webview"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </android.support.v4.widget.SwipeRefreshLayout>

And refresh the webview when user swipes screen:

SwipeRefreshLayout mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
            mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
                @Override
                public void onRefresh() {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mSwipeRefreshLayout.setRefreshing(false);
                            webview.reload();
                        }
                    }, 3000);
                }
            });

Add this before calling curl_exec($curl_handle)

curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'GET');

A nice trick to use in place of the various print formats:

(1) Pad with spaces to the right:

('hi' + '        ')[:8]

(2) Pad with leading zeros on the left:

('0000' + str(2))[-4:]

You can install the mail package in Ubuntu with below command.

For Ubuntu -:

$ sudo apt-get install -y mailutils

For CentOs-:

$ sudo yum install -y mailx

Test Mail command-:

$ echo "Mail test" | mail -s "Subject" [email protected]

• First you need to create HubNode(Server) and start the HubNode(Server) from command Line/prompt using Java: -jar selenium-server-standalone-2.44.0.jar -role hub
• Then bind the node/Client to this Hub using Hub machines IPAddress or Name with any port number >1024. For Node Machine for example: Java -jar selenium-server-standalone-2.44.0.jar -role webdriver -hub http://HubmachineIPAddress:4444/grid/register -port 5566

One more thing is that whenever we use Internet Explore or Google Chrome we need to set: System.setProperty("webdriver.ie.driver",path);

You can try to disable the only_full_group_by setting by executing the following:

mysql> set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

MySQL 8 does not accept NO_AUTO_CREATE_USER so that needs to be removed.

You can create your getValue function with the following code:

bool getValue(const std::map<int, Bar>& input, int key, Bar& out)
{
   std::map<int, Bar>::iterator foundIter = input.find(key);
   if (foundIter != input.end())
   {
      out = foundIter->second;
      return true;
   }
   return false;
}

Micro jQuery Plugin

If you want your own chainable clickToggle jQuery Method you can do it like:

jQuery.fn.clickToggle = function(a, b) {_x000D_
  return this.on("click", function(ev) { [b, a][this.$_io ^= 1].call(this, ev) })_x000D_
};_x000D_
_x000D_
// TEST:_x000D_
$('button').clickToggle(function(ev) {_x000D_
  $(this).text("B"); _x000D_
}, function(ev) {_x000D_
  $(this).text("A");_x000D_
});

<button>A</button>_x000D_
<button>A</button>_x000D_
<button>A</button>_x000D_

Simple Functions Toggler

LIVE DEMO

function a(){ console.log('a'); }
function b(){ console.log('b'); }

$("selector").click(function() { 
  return (this.tog = !this.tog) ? a() : b();
});

If you want it even shorter (why would one, right?!) you can use the Bitwise XOR ^*Docs operator like:
DEMO

  return (this.tog^=1) ? a() : b();

That's all.
_{The trick is to set to the this Object a boolean property tog, and toggle it using negation (tog = !tog)
and put the needed function calls in a Conditional Operator ?:}

In OP's example (even with multiple elements) could look like:

function a(el){ $(el).animate({width: 260}, 1500); }
function b(el){ $(el).animate({width: 30}, 1500);  }

$("selector").click(function() {
  var el = this;
  return (el.t = !el.t) ? a(el) : b(el);
}); 

ALSO: You can also store-toggle like:
DEMO:

$("selector").click(function() {
  $(this).animate({width: (this.tog ^= 1) ? 260 : 30 });
}); 

_{but it was not the OP's exact request for he's looking for a way to have two separate operations / functions}

Using Array.prototype.reverse:

_{Note: this will not store the current Toggle state but just inverse our functions positions in Array (It has it's uses...)}

You simply store your a,b functions inside an array, onclick you simply reverse the array order and execute the array[1] function:

LIVE DEMO

function a(){ console.log("a"); }
function b(){ console.log("b"); }
var ab = [a,b];

$("selector").click(function(){
  ab.reverse()[1](); // Reverse and Execute! // >> "a","b","a","b"...
});

SOME MASHUP!

jQuery DEMO
JavaScript DEMO

Create a nice function toggleAB() that will contain your two functions, put them in Array, and at the end of the array you simply execute the function [0 // 1] respectively depending on the tog property that's passed to the function from the this reference:

function toggleAB(){
  var el = this; // `this` is the "button" Element Obj reference`
  return [
    function() { console.log("b"); },
    function() { console.log("a"); }
  ][el.tog^=1]();
}

$("selector").click( toggleAB );

Just replace "UTC" with "GMT" -- simple and doesn't break correctly formatted dates:

DateTime.Parse("Tue, 1 Jan 2008 00:00:00 UTC".Replace("UTC", "GMT"))

I found there is a library for this. See example here:

https://editor.datatables.net/examples/extensions/exportButtons.html

In addition to the above code, the following Javascript library files are loaded for use in this example:

In HTML, include following scripts:

jquery.dataTables.min.js   
dataTables.editor.min.js   
dataTables.select.min.js
dataTables.buttons.min.js  
jszip.min.js    
pdfmake.min.js
vfs_fonts.js  
buttons.html5.min.js    
buttons.print.min.js

Enable buttons by adding scripts like:

<script>
$(document).ready( function () {
    $('#table-arrays').DataTable({
        dom: '<"top"Blf>rt<"bottom"ip>',
        buttons: ['copy', 'excel', 'csv', 'pdf', 'print'],
        select: true,
    });
} );
</script>

For some reason, the excel export results in corrupted file, but can be repaired. Alternatively, disable excel and use csv export.

A better pyramid can be printed this way:

The Pattern is
     $     
    $$$    
   $$$$$   
  $$$$$$$  
 $$$$$$$$$ 
$$$$$$$$$$$

public static void main(String agrs[]) {
    System.out.println("The Pattern is");
    int size = 11; //use only odd numbers here
    for (int i = 1; i <= size; i=i+2) {
        int spaceCount = (size - i)/2;
        for(int j = 0; j< size; j++) {
            if(j < spaceCount || j >= (size - spaceCount)) {
                System.out.print(" ");
            } else {
                System.out.print("$");
            }
        }
        System.out.println();
    }
}

 select sum(A),sum(B),sum(C) from mytable where id in (1,2,3);

To update the listen ports for a server: 1.Click Lock & Edit in the Change Center of the webLogic Administration Console 2.expand Environment and select Server 3.click the name of the server and select Configuration > General 4.Find Listen Port to change it 5.click Save and start server.

In Python 2.x, it is not guaranteed at all:

>>> False = 5
>>> 0 == False
False

So it could change. In Python 3.x, True, False, and None are reserved words, so the above code would not work.

In general, with booleans you should assume that while False will always have an integer value of 0 (so long as you don't change it, as above), True could have any other value. I wouldn't necessarily rely on any guarantee that True==1, but on Python 3.x, this will always be the case, no matter what.

There is: Path.ChangeExtension method. E.g.:

var result = Path.ChangeExtension(myffile, ".jpg");

In the case if you also want to physically change the extension, you could use File.Move method:

File.Move(myffile, Path.ChangeExtension(myffile, ".jpg"));

I had the error after trying to select a subset of rows:

df = df.reindex(index=my_index)

Turns out that my_index contained values that were not contained in df.index, so the reindex function inserted some new rows and filled them with nan.

have you tried eager loading?

@attachments = Job.includes(:attachments).find(1).attachments

jquery:

$(document).ready(function(){ 
  window.print();
  setTimeout(function(){ 
             window.close();
  }, 3000);
});

Typically, a cache should keep objects around some time and shall expose of them some time later. What is a good time to hold an object depends on the use case. I wanted this thing to be simple, no threads or schedulers. This approach works for me. Unlike SoftReferences, objects are guaranteed to be available some minimum amount of time. However, the do not stay around in memory until the sun turns into a red giant.

As useage example think of a slowly responding system that shall be able to check if a request has been done quite recently, and in that case not to perform the requested action twice, even if a hectic user hits the button several times. But, if the same action is requested some time later, it shall be performed again.

class Cache<T> {
    long avg, count, created, max, min;
    Map<T, Long> map = new HashMap<T, Long>();

    /**
     * @param min   minimal time [ns] to hold an object
     * @param max   maximal time [ns] to hold an object
     */
    Cache(long min, long max) {
        created = System.nanoTime();
        this.min = min;
        this.max = max;
        avg = (min + max) / 2;
    }

    boolean add(T e) {
        boolean result = map.put(e, Long.valueOf(System.nanoTime())) != null;
        onAccess();
        return result;
    }

    boolean contains(Object o) {
        boolean result = map.containsKey(o);
        onAccess();
        return result;
    }

    private void onAccess() {
        count++;
        long now = System.nanoTime();
        for (Iterator<Entry<T, Long>> it = map.entrySet().iterator(); it.hasNext();) {
            long t = it.next().getValue();
            if (now > t + min && (now > t + max || now + (now - created) / count > t + avg)) {
                it.remove();
            }
        }
    }
}

If you're talking about a web application, you should use the getRealPath from a ServletContext object.

Example:

public class MyServlet extends Servlet {
    public void doGet(HttpServletRequest req, HttpServletResponse resp) 
              throws ServletException, IOException{
         String webAppPath = getServletContext().getRealPath("/");
    }
}

Hope this helps.

This isn't as elegant as sub-classing UIButton, however if you just want something quick - what I did was create custom button, then a 1px by 1px image with the colour I'd want the button to be, and set the background of the button to that image for the highlighted state - works for my needs.

That CSS property is all you need it works for me...When previewing in Chrome you have the option to see it BW and Color(Color: Options- Color or Black and white) so if you don't have that option, then I suggest to grab this Chrome extension and make your life easier:

https://chrome.google.com/webstore/detail/print-background-colors/gjecpgdgnlanljjdacjdeadjkocnnamk?hl=en

The site you added on fiddle needs this in your media print css (you have it just need to add it...

media print CSS in the body:

@media print {

UPDATE OK so your issue is bootstrap.css...it has a media print css as well as you do....you remove that and that should give you color....you need to either do your own or stick with bootstraps print css.

When I click print on this I see color.... http://jsfiddle.net/rajkumart08/TbrtD/1/embedded/result/

If the link has javascript:, then it will run javascript, otherwise, I agree with everyone else here, there's no way to do it.

SO is smart enough to filter this out!

You can use the this customization to change the default mapping to java.util.Date

<xsd:annotation>
<xsd:appinfo>
    <jaxb:globalBindings>
        <jaxb:javaType name="java.util.Date" xmlType="xsd:dateTime"
                 parseMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.parseDateTime"
                 printMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.printDateTime"/>
    </jaxb:globalBindings>
</xsd:appinfo>

This esc behavior is IE only by the way. Instead of using jQuery use good old javascript for creating the element and it works.

var element = document.createElement('input');
element.type = 'text';
element.value = 100;
document.getElementsByTagName('body')[0].appendChild(element);

http://jsfiddle.net/gGrf9/

If you want to extend this functionality to other browsers then I would use jQuery's data object to store the default. Then set it when user presses escape.

//store default value for all elements on page. set new default on blur
$('input').each( function() {
    $(this).data('default', $(this).val());
    $(this).blur( function() { $(this).data('default', $(this).val()); });
});

$('input').keyup( function(e) {
    if (e.keyCode == 27) { $(this).val($(this).data('default')); }
});

There is a really nice answer to this problem at MySQL - How To Get Top N Rows per Each Group

Based on the solution in the referenced link, your query would be like:

SELECT Person, Group, Age
   FROM
     (SELECT Person, Group, Age, 
                  @group_rank := IF(@group = Group, @group_rank + 1, 1) AS group_rank,
                  @current_group := Group 
       FROM `your_table`
       ORDER BY Group, Age DESC
     ) ranked
   WHERE group_rank <= `n`
   ORDER BY Group, Age DESC;

where n is the top n and your_table is the name of your table.

I think the explanation in the reference is really clear. For quick reference I will copy and paste it here:

Currently MySQL does not support ROW_NUMBER() function that can assign a sequence number within a group, but as a workaround we can use MySQL session variables.

These variables do not require declaration, and can be used in a query to do calculations and to store intermediate results.

@current_country := country This code is executed for each row and stores the value of country column to @current_country variable.

@country_rank := IF(@current_country = country, @country_rank + 1, 1) In this code, if @current_country is the same we increment rank, otherwise set it to 1. For the first row @current_country is NULL, so rank is also set to 1.

For correct ranking, we need to have ORDER BY country, population DESC

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

null is an object. Its type is null. undefined is not an object; its type is undefined.

Easiest way is to use +strVal or Number(strVal)

Examples:

let strVal1 = "123.5"
let strVal2 = "One"
let val1a = +strVal1
let val1b = Number(strVal1)
let val1c = parseFloat(strVal1)
let val1d = parseInt(strVal1)
let val1e = +strVal1 - parseInt(strVal1)
let val2a = +strVal2

console.log("val1a->", val1a) // 123.5
console.log("val1b->", val1b) // 123.5
console.log("val1c->", val1c) // 123.5
console.log("val1d->", val1d) // 123
console.log("val1e->", val1e) // 0.5
console.log("val2a->", val2a) // NaN

For those who are having this issue through a VS client side once successfully added a service reference and trying to execute the first call got this exception: “The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel” If you are using (like my case) an endpoint URL with the IP address and got this exception, then you should probably need to re-add the service reference doing this steps:

• Open the endpoint URL on Internet Explorer.
• Click on the certificate error (red icon in address bar)
• Click on View certificates.
• Grab the issued to: "name" and replace the IP address or whatever name we were using and getting the error for this "name".

Try again :). Thanks

What I'm missing in the other answers is a reference to how this relates to co- and contravariance and sub- and supertypes (that is, polymorphism) in general and to Java in particular. This may be well understood by the OP, but just in case, here it goes:

Covariance

If you have a class Automobile, then Car and Truck are their subtypes. Any Car can be assigned to a variable of type Automobile, this is well-known in OO and is called polymorphism. Covariance refers to using this same principle in scenarios with generics or delegates. Java doesn't have delegates (yet), so the term applies only to generics.

I tend to think of covariance as standard polymorphism what you would expect to work without thinking, because:

List<Car> cars;
List<Automobile> automobiles = cars;
// You'd expect this to work because Car is-a Automobile, but
// throws inconvertible types compile error.

The reason of the error is, however, correct: List<Car> does not inherit from List<Automobile> and thus cannot be assigned to each other. Only the generic type parameters have an inherit relationship. One might think that the Java compiler simply isn't smart enough to properly understand your scenario there. However, you can help the compiler by giving him a hint:

List<Car> cars;
List<? extends Automobile> automobiles = cars;   // no error

Contravariance

The reverse of co-variance is contravariance. Where in covariance the parameter types must have a subtype relationship, in contravariance they must have a supertype relationship. This can be considered as an inheritance upper-bound: any supertype is allowed up and including the specified type:

class AutoColorComparer implements Comparator<Automobile>
    public int compare(Automobile a, Automobile b) {
        // Return comparison of colors
    }

This can be used with Collections.sort:

public static <T> void sort(List<T> list, Comparator<? super T> c)

// Which you can call like this, without errors:
List<Car> cars = getListFromSomewhere();
Collections.sort(cars, new AutoColorComparer());

You could even call it with a comparer that compares objects and use it with any type.

When to use contra or co-variance?

A bit OT perhaps, you didn't ask, but it helps understanding answering your question. In general, when you get something, use covariance and when you put something, use contravariance. This is best explained in an answer to Stack Overflow question How would contravariance be used in Java generics?.

So what is it then with List<? extends Map<String, String>>

You use extends, so the rules for covariance applies. Here you have a list of maps and each item you store in the list must be a Map<string, string> or derive from it. The statement List<Map<String, String>> cannot derive from Map, but must be a Map.

Hence, the following will work, because TreeMap inherits from Map:

List<Map<String, String>> mapList = new ArrayList<Map<String, String>>();
mapList.add(new TreeMap<String, String>());

but this will not:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new TreeMap<String, String>());

and this will not work either, because it does not satisfy the covariance constraint:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new ArrayList<String>());   // This is NOT allowed, List does not implement Map

What else?

This is probably obvious, but you may have already noted that using the extends keyword only applies to that parameter and not to the rest. I.e., the following will not compile:

List<? extends Map<String, String>> mapList = new List<? extends Map<String, String>>();
mapList.add(new TreeMap<String, Element>())  // This is NOT allowed

Suppose you want to allow any type in the map, with a key as string, you can use extend on each type parameter. I.e., suppose you process XML and you want to store AttrNode, Element etc in a map, you can do something like:

List<? extends Map<String, ? extends Node>> listOfMapsOfNodes = new...;

// Now you can do:
listOfMapsOfNodes.add(new TreeMap<Sting, Element>());
listOfMapsOfNodes.add(new TreeMap<Sting, CDATASection>());

if you just want the number of occurences then you can do this, $ grep -c "string_to_count" file_name

You can't.

You can only return object, or container of objects, e.g. IEnumerable<object>, IList<object>, etc.

import os

os.system("pip install beautifulsoup4")

or

import subprocess

exe = subprocess.Popen("pip install beautifulsoup4")

exe_out = exe.communicate()

print(exe_out)

I believe you should add 1 after passing it to parseInt

$('.load_more').live("click",function() { //When user clicks
          var newcurrentpageTemp = parseInt($(this).attr("id")) + 1;   
          alert(newcurrentpageTemp);
          dosomething();
      });

jQuery has very limited array functions since JavaScript has most of them itself. But here are the ones they have: Utilities - jQuery API.

As others have observed, you must either create a nullable column or provide a DEFAULT value. If that isn't flexible enough (e.g. if you need the new value to be computed for each row individually somehow), you can use the fact that in PostgreSQL, all DDL commands can be executed inside a transaction:

BEGIN;
ALTER TABLE mytable ADD COLUMN mycolumn character varying(50);
UPDATE mytable SET mycolumn = timeofday();    -- Just a silly example
ALTER TABLE mytable ALTER COLUMN mycolumn SET NOT NULL;
COMMIT;

try like this

if (!(a | b)) {
    //blahblah
}

It's same with

if (a | b) {}
else {
    // blahblah
}

To actually cover your pattern, i.e, valid file names according to your rules, I think that you need a little more. Note this doesn't match legal file names from a system perspective. That would be system dependent and more liberal in what it accepts. This is intended to match your acceptable patterns.

^([a-zA-Z0-9]+[_-])*[a-zA-Z0-9]+\.[a-zA-Z0-9]+$

Explanation:

• ^ Match the start of a string. This (plus the end match) forces the string to conform to the exact expression, not merely contain a substring matching the expression.
• ([a-zA-Z0-9]+[_-])* Zero or more occurrences of one or more letters or numbers followed by an underscore or dash. This causes all names that contain a dash or underscore to have letters or numbers between them.
• [a-zA-Z0-9]+ One or more letters or numbers. This covers all names that do not contain an underscore or a dash.
• \. A literal period (dot). Forces the file name to have an extension and, by exclusion from the rest of the pattern, only allow the period to be used between the name and the extension. If you want more than one extension that could be handled as well using the same technique as for the dash/underscore, just at the end.
• [a-zA-Z0-9]+ One or more letters or numbers. The extension must be at least one character long and must contain only letters and numbers. This is typical, but if you wanted allow underscores, that could be addressed as well. You could also supply a length range {2,3} instead of the one or more + matcher, if that were more appropriate.
• $ Match the end of the string. See the starting character.

After reading all these post It created more confuse for me.. But still all is worthfull information.. finally I found following table which will give information with simple comparision

• The injector uses recipes to create two types of objects: services and special purpose objects
• There are five recipe types that define how to create objects: Value, Factory, Service, Provider and Constant.
• Factory and Service are the most commonly used recipes. The only difference between them is that the Service recipe works better for objects of a custom type, while the Factory can produce JavaScript primitives and functions.
• The Provider recipe is the core recipe type and all the other ones are just syntactic sugar on it.
• Provider is the most complex recipe type. You don't need it unless you are building a reusable piece of code that needs global configuration.
• All special purpose objects except for the Controller are defined via Factory recipes.

And for beginner understand:- This may not correct use case but in high level this is what usecase for these three.

1. If you want to use in angular module config function should created as provider

angular.module('myApp').config(function($testProvider){_x000D_
$testProvider.someFunction();_x000D_
})

2. Ajax call or third party integrations needs to be service.
3. For Data manipulations create it as factory

For basic scenarios factory&Service behaves same.

To handle undefined variables as well as nulls, you can use substitute with deparse:

nullSafe <- function(x) {
  if (!exists(deparse(substitute(x))) || is.null(x)) {
    return(NA)
  } else {
    return(x)
  }
}

nullSafe(my.nonexistent.var)

if you use this way :

dir, err := filepath.Abs(filepath.Dir(os.Args[0]))
if err != nil {
    log.Fatal(err)
}
fmt.Println(dir)

you will get the /tmp path when you are running program using some IDE like GoLang because the executable will save and run from /tmp

i think the best way for getting the currentWorking Directory or '.' is :

import(
  "os" 
  "fmt"
  "log"
)

func main() {
  dir, err := os.Getwd()
    if err != nil {
        log.Fatal(err)
    }
  fmt.Println(dir)
}

the os.Getwd() function will return the current working directory. and its all without using of any external library :D

Unless things have changed, you're better off with

public static ByteBuffer str_to_bb(String msg, Charset charset){
    return ByteBuffer.wrap(msg.getBytes(charset));
}

public static String bb_to_str(ByteBuffer buffer, Charset charset){
    byte[] bytes;
    if(buffer.hasArray()) {
        bytes = buffer.array();
    } else {
        bytes = new byte[buffer.remaining()];
        buffer.get(bytes);
    }
    return new String(bytes, charset);
}

Usually buffer.hasArray() will be either always true or always false depending on your use case. In practice, unless you really want it to work under any circumstances, it's safe to optimize away the branch you don't need.

verse = "If you can keep your head when all about you\n Are losing theirs and blaming it on you,\nIf you can trust yourself when all men doubt you,\n But make allowance for their doubting too;\nIf you can wait and not be tired by waiting,\n Or being lied about, don’t deal in lies,\nOr being hated, don’t give way to hating,\n And yet don’t look too good, nor talk too wise:"

#2. What is the index of the first occurrence of the word 'and' in verse?
index = verse.find("and")
print("The index of the word 'and' in verse is {}".format(index))

You could try out the following code snippet:

private Point CenterOfMenuPanel<T>(T control, int height=0) where T:Control {
    Point center = new Point( 
        MenuPanel.Size.Width / 2 - control.Width * 2,
        height != 0 ? height : MenuPanel.Size.Height / 2 - control.Height / 2);

If you only want to change the route for picture.php then adding rewrite rule in .htaccess will serve your needs, but, if you want the URL rewriting as in Wordpress then PHP is the way. Here is simple example to begin with.

Folder structure

There are two files that are needed in the root folder, .htaccess and index.php, and it would be good to place the rest of the .php files in separate folder, like inc/.

root/
  inc/
  .htaccess
  index.php

.htaccess

RewriteEngine On
RewriteRule ^inc/.*$ index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]

This file has four directives:

1. RewriteEngine - enable the rewriting engine
2. RewriteRule - deny access to all files in inc/ folder, redirect any call to that folder to index.php
3. RewriteCond - allow direct access to all other files ( like images, css or scripts )
4. RewriteRule - redirect anything else to index.php

index.php

Because everything is now redirected to index.php, there will be determined if the url is correct, all parameters are present, and if the type of parameters are correct.

To test the url we need to have a set of rules, and the best tool for that is a regular expression. By using regular expressions we will kill two flies with one blow. Url, to pass this test must have all the required parameters that are tested on allowed characters. Here are some examples of rules.

$rules = array( 
    'picture'   => "/picture/(?'text'[^/]+)/(?'id'\d+)",    // '/picture/some-text/51'
    'album'     => "/album/(?'album'[\w\-]+)",              // '/album/album-slug'
    'category'  => "/category/(?'category'[\w\-]+)",        // '/category/category-slug'
    'page'      => "/page/(?'page'about|contact)",          // '/page/about', '/page/contact'
    'post'      => "/(?'post'[\w\-]+)",                     // '/post-slug'
    'home'      => "/"                                      // '/'
);

Next is to prepare the request uri.

$uri = rtrim( dirname($_SERVER["SCRIPT_NAME"]), '/' );
$uri = '/' . trim( str_replace( $uri, '', $_SERVER['REQUEST_URI'] ), '/' );
$uri = urldecode( $uri );

Now that we have the request uri, the final step is to test uri on regular expression rules.

foreach ( $rules as $action => $rule ) {
    if ( preg_match( '~^'.$rule.'$~i', $uri, $params ) ) {
        /* now you know the action and parameters so you can 
         * include appropriate template file ( or proceed in some other way )
         */
    }
}

Successful match will, since we use named subpatterns in regex, fill the $params array almost the same as PHP fills the $_GET array. However, when using a dynamic url, $_GET array is populated without any checks of the parameters.

    /picture/some+text/51

    Array
    (
        [0] => /picture/some text/51
        [text] => some text
        [1] => some text
        [id] => 51
        [2] => 51
    )

    picture.php?text=some+text&id=51

    Array
    (
        [text] => some text
        [id] => 51
    )

These few lines of code and a basic knowing of regular expressions is enough to start building a solid routing system.

    'picture'   => "/picture/(?'text'[^/]+)/(?'id'\d+)",    // '/picture/some-text/51'
    'album'     => "/album/(?'album'[\w\-]+)",              // '/album/album-slug'
    'category'  => "/category/(?'category'[\w\-]+)",        // '/category/category-slug'
    'page'      => "/page/(?'page'about|contact)",          // '/page/about', '/page/contact'
    'post'      => "/(?'post'[\w\-]+)",                     // '/post-slug'
    'home'      => "/"                                      // '/'
);

$uri = rtrim( dirname($_SERVER["SCRIPT_NAME"]), '/' );
$uri = '/' . trim( str_replace( $uri, '', $_SERVER['REQUEST_URI'] ), '/' );
$uri = urldecode( $uri );

foreach ( $rules as $action => $rule ) {
    if ( preg_match( '~^'.$rule.'$~i', $uri, $params ) ) {
        /* now you know the action and parameters so you can 
         * include appropriate template file ( or proceed in some other way )
         */
        include( INCLUDE_DIR . $action . '.php' );

        // exit to avoid the 404 message 
        exit();
    }
}

// nothing is found so handle the 404 error
include( INCLUDE_DIR . '404.php' );

How about this. using the modulo operator

if(a%b==0) 
{
    System.out.println("b is a factor of a. i.e. the result of a/b is going to be an integer");
}
else
{
    System.out.println("b is NOT a factor of a");
}

Everything in MySQL seems to be done closer to the metal than in MSSQL, And the documentation treats it that way. Especially for optimization, you'll need to understand how indexes, system configuration, and the optimizer interact under various circumstances.

The "optimizer" is more a parser. In MSSQL your query plan is often a surprise (usually good, sometimes not). In MySQL, it pretty much does what you asked it to do, the way you expected it to. Which means you yourself need to have a deep understanding of the various ways it might be done.

Not built around a good TRANSACTION model (default MyISAM engine).

File-system setup is your problem.

All the database configuration is your problem - especially various cache sizes.

Sometimes it seems best to think of it as an ad-hoc, glorified isam. Codd and Date don't carry much weight here. They would say it with no embarrassment.

Currently there's Contains function in slice package. You can read the docs here.

Sample usage :

if !slice.Contains(sliceVar, valueToFind) {
    //code here
}

Having two primary keys at the same time, is not possible. But (assuming that you have not messed the case up with composite key), may be what you might need is to make one attribute unique.

CREATE t1(
c1 int NOT NULL,
c2 int NOT NULL UNIQUE,
...,
PRIMARY KEY (c1)
);

However note that in relational database a 'super key' is a subset of attributes which uniquely identify a tuple or row in a table. A 'key' is a 'super key' that has an additional property that removing any attribute from the key, makes that key no more a 'super key'(or simply a 'key' is a minimal super key). If there are more keys, all of them are candidate keys. We select one of the candidate keys as a primary key. That's why talking about multiple primary keys for a one relation or table is being a conflict.

text='Python' searches for elements that have the exact text you provided:

import re
from BeautifulSoup import BeautifulSoup

html = """<p>exact text</p>
   <p>almost exact text</p>"""
soup = BeautifulSoup(html)
print soup(text='exact text')
print soup(text=re.compile('exact text'))

Output

[u'exact text']
[u'exact text', u'almost exact text']

"To see if the string 'Python' is located on the page http://python.org":

import urllib2
html = urllib2.urlopen('http://python.org').read()
print 'Python' in html # -> True

If you need to find a position of substring within a string you could do html.find('Python').

I just sharing my review about this. I am not surely(100% telling) that above code is not working for me and other guys also but some times I got this issue. Suppose I run the app 10 time then might be got this issue 2 to 3 three time.

I have tried above all the answers but still not solve the issue. I have implemented above all the codes and tested in different api levels (API level 26, 28, 29) and difference mobile (Samsung, Xiaomi, MIUI, Vivo, Moto, One Plus, Huawei, etc ) and getting same below issue.

Context.startForegroundService() did not then call Service.startForeground();

I have read service on google developer web site, some other blog and some stack overflow question and got the idea that this issue will happen when we call startForgroundSerivce() method but at that time service was not started.

In my case I have stop the service and after immediately start service. Below is the hint.

....//some other code
...// API level and other device auto star service condition is already set
stopService();
startService();
.....//some other code

In this case service is not started due to processing speed and low memory in RAM but startForegroundService() method is called and fire the exception.

Work for me:

new Handler().postDelayed(()->ContextCompat.startForegroundService(activity, new Intent(activity, ChatService.class)), 500);

I have change code and set 500 milliseconds delay to call startService() method and issue is solved. This is not perfect solution because this way app's performance goes downgrade.

Note: This is only for Foreground and Background service only. Don't tested when using Bind service. I am sharing this because only this is the way I have solved this issue.

You may use jQuery:

<input type="text" name="IP" id="IP" value=""/>
@Html.ActionLink(@Resource.ButtonTitleAdd, "Add", "Configure", new { ipValue ="xxx", TypeId = "1" }, new {@class = "link"})

<script>
  $(function () {
    $('.link').click(function () {
      var ipvalue = $("#IP").val();
      this.href = this.href.replace("xxx", ipvalue);
    });
  });
</script>

You have two options:

Either use:

sb.setLength(0);  // It will just discard the previous data, which will be garbage collected later.  

Or use:

sb.delete(0, sb.length());  // A bit slower as it is used to delete sub sequence.  

NOTE

Avoid declaring StringBuffer or StringBuilder objects within the loop else it will create new objects with each iteration. Creating of objects requires system resources, space and also takes time. So for long run, avoid declaring them within a loop if possible.

Nathan Lee's answer is perfect. I just wanted to add something about position:absolute;. If you wanted to use position:absolute; like you had in your code, you have to think of it as pushing it away from one side of the page.

For example, if you wanted your div to be somewhere in the bottom, you would have to use position:absolute; top:500px;. That would push your div 500px from the top of the page. Same rule applies for all other directions.

DEMO

The answer from @ben almost works for me except that my dependencies are too big and I got the following error

Execution failed for task ':jar'.
> archive contains more than 65535 entries.

  To build this archive, please enable the zip64 extension.

To fix this problem, I have to use the following code

mainClassName = "com.company.application.Main"

jar {
  manifest { 
    attributes "Main-Class": "$mainClassName"
  }  
  zip64 = true
  from {
    configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
  }
}

You should do like this:

@Html.DropDownListFor(m => m.ContribType, 
                new SelectList(Model.ContribTypeOptions, 
                               "ContribId", "Value"))

Where:

m => m.ContribType

is a property where the result value will be.

Check your environment variables.

In my case I had JAVA_HOME set in the System variables as well as in my User Account variables and the latter was set to a wrong version of Java. I also had the same problem with the Path variable.

After deleting JAVA_HOME from my User Account variables and removing the wrong path from the Path variable it worked correctly.

You should not execute resource intensive tasks in the main thread. It will make the UI unresponsive and you will get an ANR. It seems like you will be doing resource intensive stuff and want the user to see the ProgressDialog. You can take a look at http://developer.android.com/reference/android/os/AsyncTask.html to do resource intensive tasks. It also shows you how to use a ProgressDialog.

GET:

// GET JSON Response
public WeatherResponseModel GET(string url) {
    WeatherResponseModel model = new WeatherResponseModel();
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    try {
        WebResponse response = request.GetResponse();
        using(Stream responseStream = response.GetResponseStream()) {
            StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
            model = JsonConvert.DeserializeObject < WeatherResponseModel > (reader.ReadToEnd());
        }
    } catch (WebException ex) {
        WebResponse errorResponse = ex.Response;
        using(Stream responseStream = errorResponse.GetResponseStream()) {
            StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
            String errorText = reader.ReadToEnd();
            // Log errorText
        }
        throw;
    }
    return model;
}

POST:

// POST a JSON string
void POST(string url, string jsonContent) {
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";

    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
    Byte[]byteArray = encoding.GetBytes(jsonContent);

    request.ContentLength = byteArray.Length;
    request.ContentType =  @ "application/json";

    using(Stream dataStream = request.GetRequestStream()) {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }

    long length = 0;
    try {
        using(HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {
            // Got response
            length = response.ContentLength;
        }

            // Log errorText
        }
        throw;

}

Note: To serialize and desirialze JSON, I used the Newtonsoft.Json NuGet package.

This code worked for me

public static void main(String[] args) {
    try {
        java.net.URL myUr = new java.net.URL("http://path");
        System.out.println("Instantiated new URL: " + connection_url);
    }
    catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

Instantiated new URL: http://path

I'm not familiar with tortoise, but with subversion to linux i would type

svn status

Some googling tells me that tortoise also supports commandline commandos, try svn status in the folder that contains the svn repository.

It looks like that this limitation can be avoided if you use the following URL pattern:

https://googledrive.com/host/file-id

For your case the download URL will look like this - https://googledrive.com/host/0ByvXJAlpPqQPYWNqY0V3MGs0Ujg

Please keep in mind that this method works only if file is shared with "Public on the web" option.

Add new column to DataTable and use column Expression property to set your Status expression.

Here you can find good example: DataColumn.Expression Property

DataTable and DataColumn Expressions in ADO.NET - Calculated Columns

UPDATE

Code sample:

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("colBestBefore", typeof(DateTime)));
dt.Columns.Add(new DataColumn("colStatus", typeof(string)));

dt.Columns["colStatus"].Expression = String.Format("IIF(colBestBefore < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

dt.Rows.Add(DateTime.Now.AddDays(-1));
dt.Rows.Add(DateTime.Now.AddDays(1));
dt.Rows.Add(DateTime.Now.AddDays(2));
dt.Rows.Add(DateTime.Now.AddDays(-2));

demoGridView.DataSource = dt;

UPDATE #2

dt.Columns["colStatus"].Expression = String.Format("IIF(CONVERT(colBestBefore, 'System.DateTime') < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

Just found this, and its even shorter.

    return int(time.time()+300)

If you have any NamedQueries in your entity classes, then check the stack trace for compilation errors. A malformed query which cannot be compiled can cause failure to load the persistence context.

This is working nicely.

UPDATE state SET name = CONCAT(UCASE(LEFT(name, 1)), LCASE(SUBSTRING(name, 2)));

If you're going to be using this often (and on multiple arrays), extend the Array object to create an unset function.

Array.prototype.unset = function(value) {
    if(this.indexOf(value) != -1) { // Make sure the value exists
        this.splice(this.indexOf(value), 1);
    }   
}

tag_story.unset(56)

Try this one, I think this will works for you

update ud

set ud.assid = sale.assid

from ud 

Inner join sale on ud.id = sale.udid

where sale.udid is not null

You can draw the image on the canvas and let the user draw on top of that.

The drawImage() function will help you with that, see https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Canvas_tutorial/Using_images

Here is the algorithm I use to crypt with MD5.It returns your crypted output.

   public class CryptWithMD5 {
   private static MessageDigest md;

   public static String cryptWithMD5(String pass){
    try {
        md = MessageDigest.getInstance("MD5");
        byte[] passBytes = pass.getBytes();
        md.reset();
        byte[] digested = md.digest(passBytes);
        StringBuffer sb = new StringBuffer();
        for(int i=0;i<digested.length;i++){
            sb.append(Integer.toHexString(0xff & digested[i]));
        }
        return sb.toString();
    } catch (NoSuchAlgorithmException ex) {
        Logger.getLogger(CryptWithMD5.class.getName()).log(Level.SEVERE, null, ex);
    }
        return null;


   }
}

You cannot decrypt MD5, but you can compare outputs since if you put the same string in this method it will have the same crypted output.If you want to decrypt you need to use the SHA.You will never use decription for a users password.For that always use MD5.That exception is pretty redundant.It will never throw it.

I've created an extension method for this which makes use of SemaphoreSlim and also allows to set maximum degree of parallelism

    /// <summary>
    /// Concurrently Executes async actions for each item of <see cref="IEnumerable<typeparamref name="T"/>
    /// </summary>
    /// <typeparam name="T">Type of IEnumerable</typeparam>
    /// <param name="enumerable">instance of <see cref="IEnumerable<typeparamref name="T"/>"/></param>
    /// <param name="action">an async <see cref="Action" /> to execute</param>
    /// <param name="maxDegreeOfParallelism">Optional, An integer that represents the maximum degree of parallelism,
    /// Must be grater than 0</param>
    /// <returns>A Task representing an async operation</returns>
    /// <exception cref="ArgumentOutOfRangeException">If the maxActionsToRunInParallel is less than 1</exception>
    public static async Task ForEachAsyncConcurrent<T>(
        this IEnumerable<T> enumerable,
        Func<T, Task> action,
        int? maxDegreeOfParallelism = null)
    {
        if (maxDegreeOfParallelism.HasValue)
        {
            using (var semaphoreSlim = new SemaphoreSlim(
                maxDegreeOfParallelism.Value, maxDegreeOfParallelism.Value))
            {
                var tasksWithThrottler = new List<Task>();

                foreach (var item in enumerable)
                {
                    // Increment the number of currently running tasks and wait if they are more than limit.
                    await semaphoreSlim.WaitAsync();

                    tasksWithThrottler.Add(Task.Run(async () =>
                    {
                        await action(item).ContinueWith(res =>
                        {
                            // action is completed, so decrement the number of currently running tasks
                            semaphoreSlim.Release();
                        });
                    }));
                }

                // Wait for all tasks to complete.
                await Task.WhenAll(tasksWithThrottler.ToArray());
            }
        }
        else
        {
            await Task.WhenAll(enumerable.Select(item => action(item)));
        }
    }

Sample Usage:

await enumerable.ForEachAsyncConcurrent(
    async item =>
    {
        await SomeAsyncMethod(item);
    },
    5);

You just need to use the Gradle Application plugin:

apply plugin:'application'
mainClassName = "org.gradle.sample.Main"

And then simply gradle run.

As Teresa points out, you can also configure mainClassName as a system property and run with a command line argument.

The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.

The way you get your original array back is by using Convert.FromBase64String:

 byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);

If you are facing this issue in a .ts file which is only there to provide you some constant values, then you can just

rename your .ts file to .js file

and the error will not come again.

I think following can give broader coverage in fewer lines

import org.apache.commons.exec.OS;

if (OS.isFamilyWindows()){
                //load some property
            }
else if (OS.isFamilyUnix()){
                //load some other property
            }

More details here: https://commons.apache.org/proper/commons-exec/apidocs/org/apache/commons/exec/OS.html

It's possible by accessing the key as index

for example:

Dictionary<string, int> dictionary = new Dictionary<string, int>();
dictionary["test"] = 1;
dictionary["test"] += 1;
Console.WriteLine (dictionary["test"]); // will print 2

I got this issue when compile react-native-fbsdk

I resolved this issue by change build.gradle of react-native-fbsdk

from

compile('com.facebook.android:facebook-android-sdk:4.+')

to

compile('com.facebook.android:facebook-android-sdk:4.28.0')

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

If the column is a timestamp you can do the following:

        if(fromDate!=null){
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) >= TO_DATE('" + dataFrom + "','dd/mm/yyyy')"));
        }
        if(toDate!=null){               
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) <= TO_DATE('" + dataTo + "','dd/mm/yyyy')"));
        }

        resultDB = criteria.list();

This resolved my issue if you do not want to make the app available to the public (keeping Status & Review on NO)

I had to sign out of the previous account on the Facebook App and also remove the Facebook account in Settings. Removing just from the Settings will not remove the error because the App itself still has the previous account logged in.

If you have set your Roles as Administrator/Developer/Tester, you can put in that account login info in and it should work then.

If the delete is recent enough (Like an Oh-NO! moment) you should still have a message:

Deleted branch <branch name> (was abcdefghi).

you can still run:

git checkout abcdefghi

git checkout -b <some new branch name or the old one>

Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:

"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage

which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh "thought" that it is run in the regular terminal and since it may be accomplished by simple posix functions, it is beyond what simple bash offers.

Use the ViewContext and look at the RouteData collection to extract both the controller and action elements. But I think setting some data variable that indicates the application context (e.g., "editmode" or "error") rather than controller/action reduces the coupling between your views and controllers.

much easier use it

<input type="button" id="loadFileXml" value="Custom Button Name"onclick="document.getElementById('file').click();" />
<input type="file" style="display:none;" id="file" name="file"/>

There's a good discussion of this issue here.

I ran into the same architectural problem: wanting a way of giving my application more organization and internal namespaces, without:

• mixing application modules with external dependencies or bothering with private npm repos for application-specific code
• using relative requires, which make refactoring and comprehension harder
• using symlinks or changing the node path, which can obscure source locations and don't play nicely with source control

In the end, I decided to organize my code using file naming conventions rather than directories. A structure would look something like:

• npm-shrinkwrap.json
• package.json
• node_modules
  • ...
• src
  • app.js
  • app.config.js
  • app.models.bar.js
  • app.models.foo.js
  • app.web.js
  • app.web.routes.js
  • ...

Then in code:

var app_config = require('./app.config');
var app_models_foo = require('./app.models.foo');

or just

var config = require('./app.config');
var foo = require('./app.models.foo');

and external dependencies are available from node_modules as usual:

var express = require('express');

In this way, all application code is hierarchically organized into modules and available to all other code relative to the application root.

The main disadvantage is of course that in a file browser, you can't expand/collapse the tree as though it was actually organized into directories. But I like that it's very explicit about where all code is coming from, and it doesn't use any 'magic'.

You don't necessarily need to have an HTML page. Open Chrome, press Ctrl+Shift+j and it opens the JavaScript console where you can write and test your code.

You can do this by adding a div i.e. centerBlock. And give this property in CSS to center the image or any content. Here is the code:

<div class="container">
    <div class="row">
        <div class="col-sm-4 col-md-4 col-lg-4">
            <div class="centerBlock">
                <img class="img-responsive" src="img/some-image.png" title="This image needs to be centered">
            </div>
        </div>
        <div class="col-sm-8 col-md-8 col-lg-8">
            Some content not important at this moment
        </div>
    </div>
</div>


// CSS

.centerBlock {
  display: table;
  margin: auto;
}

EDIT

Here are two versions. One using ArrayList and other using HashSet

Compare them and create your own version from this, until you get what you need.

This should be enough to cover the:

P.S: It is not a school assignment :) So if you just guide me it will be enough

part of your question.

continuing with the original answer:

You may use a java.util.Collection and/or java.util.ArrayList for that.

The retainAll method does the following:

Retains only the elements in this collection that are contained in the specified collection

see this sample:

import java.util.Collection;
import java.util.ArrayList;
import java.util.Arrays;

public class Repeated {
    public static void main( String  [] args ) {
        Collection listOne = new ArrayList(Arrays.asList("milan","dingo", "elpha", "hafil", "meat", "iga", "neeta.peeta"));
        Collection listTwo = new ArrayList(Arrays.asList("hafil", "iga", "binga", "mike", "dingo"));

        listOne.retainAll( listTwo );
        System.out.println( listOne );
    }
}

EDIT

For the second part ( similar values ) you may use the removeAll method:

Removes all of this collection's elements that are also contained in the specified collection.

This second version gives you also the similar values and handles repeated ( by discarding them).

This time the Collection could be a Set instead of a List ( the difference is, the Set doesn't allow repeated values )

import java.util.Collection;
import java.util.HashSet;
import java.util.Arrays;

class Repeated {
      public static void main( String  [] args ) {

          Collection<String> listOne = Arrays.asList("milan","iga",
                                                    "dingo","iga",
                                                    "elpha","iga",
                                                    "hafil","iga",
                                                    "meat","iga", 
                                                    "neeta.peeta","iga");

          Collection<String> listTwo = Arrays.asList("hafil",
                                                     "iga",
                                                     "binga", 
                                                     "mike", 
                                                     "dingo","dingo","dingo");

          Collection<String> similar = new HashSet<String>( listOne );
          Collection<String> different = new HashSet<String>();
          different.addAll( listOne );
          different.addAll( listTwo );

          similar.retainAll( listTwo );
          different.removeAll( similar );

          System.out.printf("One:%s%nTwo:%s%nSimilar:%s%nDifferent:%s%n", listOne, listTwo, similar, different);
      }
}

Output:

$ java Repeated
One:[milan, iga, dingo, iga, elpha, iga, hafil, iga, meat, iga, neeta.peeta, iga]

Two:[hafil, iga, binga, mike, dingo, dingo, dingo]

Similar:[dingo, iga, hafil]

Different:[mike, binga, milan, meat, elpha, neeta.peeta]

If it doesn't do exactly what you need, it gives you a good start so you can handle from here.

Question for the reader: How would you include all the repeated values?

Just to point out that cordova brings in it's own npm with the graceful-fs dependency, so if you use Cordova make sure that it is the latest so you get the latest graceful-fs from that as well.

To complement ruslik's answer, in C++14 you can use this construction:

delete std::exchange(heapObject, nullptr);

You can use :

-XX:MaxPermSize=128m

to increase the space. But this usually only postpones the inevitable.

You can also enable the PermGen to be garbage collected

-XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled

Usually this occurs when doing lots of redeploys. I am surprised you have it using something like indexing. Use virtualvm or jconsole to monitor the Perm gen space and check it levels off after warming up the indexing.

Maybe you should consider changing to another JVM like the IBM JVM. It does not have a Permanent Generation and is immune to this issue.

You can create an empty project by selecting the "Empty Project" from the "General" group of Visual C++ projects (maybe that project template isn't included in Express?).

To fix the problem in the project you already have, open the project properties and navigate to:

Configuration Properties | C/C++ | Precompiled Headers

And choose "Not using Precompiled Headers" for the "Precompiled Header" option.

Where is x found?

x is not found as you haven't defined it. :-) It could be found in code1 (global) or code3 (local) if you put it there.

code2 (class members) aren't visible to code inside methods of the same class — you would usually access them using self. code4/code5 (loops) live in the same scope as code3, so if you wrote to x in there you would be changing the x instance defined in code3, not making a new x.

Python is statically scoped, so if you pass ‘spam’ to another function spam will still have access to globals in the module it came from (defined in code1), and any other containing scopes (see below). code2 members would again be accessed through self.

lambda is no different to def. If you have a lambda used inside a function, it's the same as defining a nested function. In Python 2.2 onwards, nested scopes are available. In this case you can bind x at any level of function nesting and Python will pick up the innermost instance:

x= 0
def fun1():
    x= 1
    def fun2():
        x= 2
        def fun3():
            return x
        return fun3()
    return fun2()
print fun1(), x

2 0

fun3 sees the instance x from the nearest containing scope, which is the function scope associated with fun2. But the other x instances, defined in fun1 and globally, are not affected.

Before nested_scopes — in Python pre-2.1, and in 2.1 unless you specifically ask for the feature using a from-future-import — fun1 and fun2's scopes are not visible to fun3, so S.Lott's answer holds and you would get the global x:

0 0

You can use the Dictionary data type in python. It's very very similar to the hash—and it also supports nesting, similar to the to nested hash.

Example:

dict = {'Name': 'Zara', 'Age': 7, 'Class': 'First'}
dict['Age'] = 8; # update existing entry
dict['School'] = "DPS School" # Add new entry

print ("dict['Age']: ", dict['Age'])
print ("dict['School']: ", dict['School'])

For more information, please reference this tutorial on the dictionary data type.

var paramsdate=01+'%s'+12+'%s'+2012+'%s';

request.get("https://www.exampleurl.com?fromDate="+paramsDate;

Your best bet would be using the RFC defined mime-type audio/mpeg.

If you're using org.codehaus.jackson, this has been possible since 1.6. You can convert a JsonNode to a POJO with ObjectMapper#readValue: http://jackson.codehaus.org/1.9.4/javadoc/org/codehaus/jackson/map/ObjectMapper.html#readValue(org.codehaus.jackson.JsonNode, java.lang.Class)

    ObjectMapper mapper = new ObjectMapper();
    JsonParser jsonParser = mapper.getJsonFactory().createJsonParser("{\"foo\":\"bar\"}");
    JsonNode tree = jsonParser.readValueAsTree();
    // Do stuff to the tree

As of jQuery version 1.7, the off() method is the new replacement for the unbind(), die() and undelegate() methods. This method brings a lot of consistency to the API, and we recommend that you use this method, as it simplifies the jQuery code base.

This gives:

$("#someid").off("click").live("click",function(){...

or

$("#someid").off("click").bind("click",function(){...

Try

location+''

let url = location+'';_x000D_
_x000D_
console.log(url);

In a single line you could do:

private static File[] bar(){
    return new File[]{};
}

1. Use Arrays.toString( arl.get(0) ).

2. arl.get(0)[1]

Use:

//REVENUE_YEAR[starts-with(.,'2552')]/../REGION/text() 

It is not exactly for Xcode5 but this question links people who want to check where are provisioning profiles:
Following documentation https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistributionGuide/MaintainingCertificates/MaintainingCertificates.html

1. Choose Xcode > Preferences.
2. Click Accounts at the top of the window.
3. Select the team you want to view, and click View Details. In the dialog that appears, view your signing identities and provisioning profiles. If a Create button appears next to a certificate, it hasn’t been created yet. If a Download button appears next to a provisioning profile, it’s not on your Mac.

Ten you can start context menu on each profile and click "Show in Finder" or "Move to Trash".

I could not understand those 3 rules in the specs too well -- hope to have something that is more plain English -- but here is what I gathered from JavaScript: The Definitive Guide, 6th Edition, David Flanagan, O'Reilly, 2011:

Quote:

JavaScript does not treat every line break as a semicolon: it usually treats line breaks as semicolons only if it can’t parse the code without the semicolons.

Another quote: for the code

var a
a
=
3 console.log(a)

JavaScript does not treat the second line break as a semicolon because it can continue parsing the longer statement a = 3;

and:

two exceptions to the general rule that JavaScript interprets line breaks as semicolons when it cannot parse the second line as a continuation of the statement on the first line. The first exception involves the return, break, and continue statements

... If a line break appears after any of these words ... JavaScript will always interpret that line break as a semicolon.

... The second exception involves the ++ and -- operators ... If you want to use either of these operators as postfix operators, they must appear on the same line as the expression they apply to. Otherwise, the line break will be treated as a semicolon, and the ++ or -- will be parsed as a prefix operator applied to the code that follows. Consider this code, for example:

x 
++ 
y

It is parsed as x; ++y;, not as x++; y

So I think to simplify it, that means:

In general, JavaScript will treat it as continuation of code as long as it makes sense -- except 2 cases: (1) after some keywords like return, break, continue, and (2) if it sees ++ or -- on a new line, then it will add the ; at the end of the previous line.

The part about "treat it as continuation of code as long as it makes sense" makes it feel like regular expression's greedy matching.

With the above said, that means for return with a line break, the JavaScript interpreter will insert a ;

(quoted again: If a line break appears after any of these words [such as return] ... JavaScript will always interpret that line break as a semicolon)

and due to this reason, the classic example of

return
{ 
  foo: 1
}

will not work as expected, because the JavaScript interpreter will treat it as:

return;   // returning nothing
{
  foo: 1
}

There has to be no line-break immediately after the return:

return { 
  foo: 1
}

for it to work properly. And you may insert a ; yourself if you were to follow the rule of using a ; after any statement:

return { 
  foo: 1
};

Moreover, mousemove events are not triggered if you perform drag'n'drop over a browser window. To track mouse coordinates during drag'n'drop you should attach handler for document.ondragover event and use it's originalEvent property.

Example:

var globalDragOver = function (e)
{
    var original = e.originalEvent;
    if (original)
    {
        window.x = original.pageX;
        window.y = original.pageY;
    }
}

Those who still have the problem with onAttach(Activity activity), Its just changed to Context -

    @Override
public void onAttach(Context context) {
    super.onAttach(context);
    this.context = context;
}

In most cases saving the context will be enough for you - for example if you want to do getResources() you can do it straight from the context. If you still need to make the context into your Activity do so -

 @Override
public void onAttach(Context context) {
    super.onAttach(context);
    mActivity a; //Your activity class - will probably be a global var.
    if (context instanceof mActivity){
        a=(mActivity) context;
    }
}

As suggested by user1868713.

You could descendingly order the tabele by id and limit the number of results to one:

SELECT id FROM tablename ORDER BY id DESC LIMIT 1

BUT: ORDER BY rearranges the entire table for this request. So if you have a lot of data and you need to repeat this operation several times, I would not recommend this solution.

I prefer to use a configuration file. It allows me to switch logging levels, locations, etc without changing code when I go from development to release. I simply package a different config file with the same name, and with the same defined loggers.

import logging.config
if __name__ == '__main__':
    # Configure the logger
    # loggerConfigFileName: The name and path of your configuration file
    logging.config.fileConfig(path.normpath(loggerConfigFileName))

    # Create the logger
    # Admin_Client: The name of a logger defined in the config file
    mylogger = logging.getLogger('Admin_Client')

    msg='Bite Me'
    myLogger.debug(msg)
    myLogger.info(msg)
    myLogger.warn(msg)
    myLogger.error(msg)
    myLogger.critical(msg)

    # Shut down the logger
    logging.shutdown()

Here is my code for the log config file

#These are the loggers that are available from the code
#Each logger requires a handler, but can have more than one
[loggers]
keys=root,Admin_Client


#Each handler requires a single formatter
[handlers]
keys=fileHandler, consoleHandler

# because it hangs!

args=(sys.stdout,)# The comma is correct, because the parser is looking for args

# This causes a new file to be created for each script

Quoting the iPhone OS Technology Overview:

iPhone OS provides support for full-screen video playback through the Media Player framework (MediaPlayer.framework). This framework supports the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename extensions and using the following compression standards:

• H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• Numerous audio formats, including the ones listed in “Audio Technologies”

For information about the classes of the Media Player framework, see Media Player Framework Reference.

I would like to expand open jfs's answer, which worked great for my problem: sorting two lists by a third, decorated list:

We can create our decorated list in any way, but in this case we will create it from the elements of one of the two original lists, that we want to sort:

# say we have the following list and we want to sort both by the algorithms name 
# (if we were to sort by the string_list, it would sort by the numerical 
# value in the strings)
string_list = ["0.123 Algo. XYZ", "0.345 Algo. BCD", "0.987 Algo. ABC"]
dict_list = [{"dict_xyz": "XYZ"}, {"dict_bcd": "BCD"}, {"dict_abc": "ABC"}]

# thus we need to create the decorator list, which we can now use to sort
decorated = [text[6:] for text in string_list]  
# decorated list to sort
>>> decorated
['Algo. XYZ', 'Algo. BCD', 'Algo. ABC']

Now we can apply jfs's solution to sort our two lists by the third

# create and sort the list of indices
sorted_indices = list(range(len(string_list)))
sorted_indices.sort(key=decorated.__getitem__)

# map sorted indices to the two, original lists
sorted_stringList = list(map(string_list.__getitem__, sorted_indices))
sorted_dictList = list(map(dict_list.__getitem__, sorted_indices))

# output
>>> sorted_stringList
['0.987 Algo. ABC', '0.345 Algo. BCD', '0.123 Algo. XYZ']
>>> sorted_dictList
[{'dict_abc': 'ABC'}, {'dict_bcd': 'BCD'}, {'dict_xyz': 'XYZ'}]

Change your select box options value:

<select id="cmbMake" name="Make" >
     <option value="">Select Manufacturer</option>
     <option value="Any">--Any--</option>
     <option value="Toyota">Toyota</option>
     <option value="Nissan">Nissan</option>
  </select>

You cann't get the text of selected option in php. it will give only the value of selected option.

EDITED:

<select id="cmbMake" name="Make" >
     <option value="0">Select Manufacturer</option>
     <option value="1_Any">--Any--</option>
     <option value="2_Toyota">Toyota</option>
     <option value="3_Nissan">Nissan</option>
  </select>

ON php file:

$maker = mysql_real_escape_string($_POST['Make']);
$maker = explode("_",$maker);
echo $maker[1]; //give the Toyota
echo $maker[0]; //give the key 2

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

With my experiance the best open source option will be UIKIT with its uikit slider component. and it is very easy to implement for example in your case you could do something like this.

<div data-uk-slider>
<div class="uk-slider-container">
    <ul class="uk-slider uk-grid-width-medium-1-4"> // width of the elements
        <li>...</li> //slide elements
        ...
    </ul>
</div>

You do not use "cd" to change the directory from which to run your commands. You need the full path of the executable you want to run.

Also, listing the contents of a directory is easier to do with the File/Directory classes

Swift 3.0 implementation

extension UIView {
    func getSnapshotImage() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, 0)
        drawHierarchy(in: bounds, afterScreenUpdates: false)
        let snapshotImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return snapshotImage
    }
}

For php, when you use checkboxes for multiple values, the name always ends with []. We can use this to make the solution a bit more generic. And, since I put my error message in a data-message-value-missing attribute, I use:

$form.on('change', 'input[type=checkbox][name$="[]"]', e => {
    const $inputs = $('input[type=checkbox][name="' + e.target.name + '"]');
    const $targetInp = $inputs.filter('[data-message-value-missing]');
    if($inputs.filter(':checked').length) {
        $targetInp.removeAttr('required');
        $form.find('label.error').html('');
    } else {
        $targetInp.attr('required', 'required');
    }
});

To make this work, set the data-message-value-missing and the required on only one (the last) input:

<ul>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 1"><label>Box 1</label></li>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 2"><label>Box 2</label></li>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 3"><label>Box 3</label></li>
   <li><input name="BoxSelect[]" type="checkbox" value="Box 4" required data-message-value-missing="Select at least one"><label>Box 4</label></li>
</ul>

I excluded the code to handle the checkValidity(), etc. Seems beyond the scope of this question...

You can simply implement your own compare function

[compareWith]="compareItems"

See as well the docu. So the complete code would look like:

  <div>
    <mat-select
        [(value)]="selected2" [compareWith]="compareItems">
      <mat-option
          *ngFor="let option of options2"
          value="{{ option.id }}">
        {{ option.name }}
      </mat-option>
    </mat-select>
  </div>

and in the Typescript file:

  compareItems(i1, i2) {
    return i1 && i2 && i1.id===i2.id;
  }

#include <stdio.h>
#include "opencv.hpp"


int main(){

    CvCapture *camera=cvCaptureFromFile("http://username:pass@cam_address/axis-cgi/mjpg/video.cgi?resolution=640x480&req_fps=30&.mjpg");
    if (camera==NULL)
        printf("camera is null\n");
    else
        printf("camera is not null");

    cvNamedWindow("img");
    while (cvWaitKey(10)!=atoi("q")){
        double t1=(double)cvGetTickCount();
        IplImage *img=cvQueryFrame(camera);
        double t2=(double)cvGetTickCount();
        printf("time: %gms  fps: %.2g\n",(t2-t1)/(cvGetTickFrequency()*1000.), 1000./((t2-t1)/(cvGetTickFrequency()*1000.)));
        cvShowImage("img",img);
    }
    cvReleaseCapture(&camera);
}

I haven't ever seen such a thing, but there is this dev tool that includes a syntax checker for oracle, mysql, db2, and sql server... http://www.sqlparser.com/index.php

However this seems to be just the library. You'd need to build an app to leverage the parser to do what you want. And the Enterprise edition that includes all of the databases would cost you $450... ouch!

EDIT: And, after saying that - it looks like someone might already have done what you want using that library: http://www.wangz.net/cgi-bin/pp/gsqlparser/sqlpp/sqlformat.tpl

The online tool doesn't automatically check against each DB though, you need to run each manually. Nor can I say how good it is at checking the syntax. That you'd need to investigate yourself.

If a node is so unhealthy that the master can't get status from it -- Kubernetes may not be able to restart the node. And if health checks aren't working, what hope do you have of accessing the node by SSH?

In this case, you may have to hard-reboot -- or, if your hardware is in the cloud, let your provider do it.

For example, the AWS EC2 Dashboard allows you to right-click an instance to pull up an "Instance State" menu -- from which you can reboot/terminate an unresponsive node.

Before doing this, you might choose to kubectl cordon node for good measure. And you may find kubectl delete node to be an important part of the process for getting things back to normal -- if the node doesn't automatically rejoin the cluster after a reboot.

Why would a node become unresponsive? Probably some resource has been exhausted in a way that prevents the host operating system from handling new requests in a timely manner. This could be disk, or network -- but the more insidious case is out-of-memory (OOM), which Linux handles poorly.

To help Kubernetes manage node memory safely, it's a good idea to do both of the following:

• Reserve some memory for the system.
• Be very careful with (avoid) opportunistic memory specifications for your pods. In other words, don't allow different values of requests and limits for memory.

The idea here is to avoid the complications associated with memory overcommit, because memory is incompressible, and both Linux and Kubernetes' OOM killers may not trigger before the node has already become unhealthy and unreachable.

There's been a method for this for ages:

ruby -e 'puts Gem::Specification.all_names'

You can also use ViewPager.SimpleOnPageChangeListener instead of ViewPager.OnPageChangeListener and override only those methods you want to use.

viewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

    // optional 
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { }

    // optional 
    @Override
    public void onPageSelected(int position) { }

    // optional 
    @Override
    public void onPageScrollStateChanged(int state) { }
});

Hope this help :)

Edit: As per android APIs, setOnPageChangeListener (ViewPager.OnPageChangeListener listener) is deprecated. Please check this url:- Android ViewPager API

From the man page, npm start:

runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.

Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.

Anyhow, what really happens is that npm looks in your package.json file, and if you have something like

"scripts": { "start": "coffee server.coffee" }

then it will do that. If npm can't find your start script, it defaults to:

node server.js

I frequently stumble upon this issue while bulk moving files to new subdirectories. Ideally, I want to do this:

mv * newdir/  

Most of the answers in this thread propose to mkdir and then mv, but this results in:

mkdir newdir && mv * newdir 
mv: cannot move 'newdir/' to a subdirectory of itself

The problem I face is slightly different in that I want to blanket move everything, and, if I create the new directory before moving then it also tries to move the new directory to itself. So, I work around this by using the parent directory:

mkdir ../newdir && mv * ../newdir && mv ../newdir .

Caveats: Does not work in the root folder (/).

Had the same issue , I finally got it working after some trying. Here are the 8 html tags that I used on my web page to get the preview working :

In <head> tag:

<meta property="og:title" content="ABC Blabla 2020 Friday" />
<meta property="og:url" content="https://bla123.neocities.org/mp/friday.html" />
<meta property="og:description" content="Photo Album">
<meta property="og:image" itemprop="image" content="https://bla123.neocities.org/mp/images/thumbs/IMG_327.JPG"/>
<meta property="og:type" content="article" />
<meta property="og:locale" content="en_GB" />

In <body> tag:

<link itemprop="thumbnailUrl" href="https://bla123.neocities.org/mp/images/thumbs/IMG_327.JPG">

<span itemprop="thumbnail" itemscope itemtype="http://schema.org/ImageObject">
<link itemprop="url" href="https://bla123.neocities.org/mp/images/thumbs/IMG_327.JPG">
</span>

These 8 tags ( 6 in head , 2 in body) worked perfectly.

Tips:

1.Use the exact image location URL instead of directory format i.e. don't use images/OG_thumb.jpg

2.Case sensitive file extension: If the image extension name on your hosting provider is ".JPG" then do not use ".jpg" or ".jpeg' . I observed that based on hosting provider and browser combination error may or may not occur, so to be safe its easier to just match the case of file extension.

3.After doing above steps if the thumbnail preview is still not showing up in WhatsApp message then:

a. Force stop the mobile app ( I tried in Android) and try again

b.Use online tool to preview the OG tag eg I used : https://searchenginereports.net/open-graph-checker

c. In mobile browser paste direct link to the OG thumb and refresh the browser 4-5 times . eg https://bla123neocities.org/nmp/images/thumbs/IMG_327.JPG

Its very very easy with Carbon. $date = "2016-02-16"; // Or Your date $newDate = Carbon::createFromFormat('Y-m-d', $date)->addYear(1);

As you can see in the documentation of JSHint you can change options per function or per file. In your case just place a comment in your file or even more local just in the function that uses eval:

/*jshint evil:true */

function helloEval(str) {
    /*jshint evil:true */
    eval(str);
}

Couldn't your query just be written as:

SELECT u1.name as UserName from Message m1, User u1 
  WHERE u1.uid = m1.UserFromID GROUP BY u1.name HAVING count(m1.UserFromId)>3

That should also help with the known speed issues with subqueries in MySQL

Try using:

console.log($("#"+d));

This will remove the extra quotes you were using.

You may also get :

Could not load file or assembly 'WebMatrix.Data, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

This has moved to this package

 Install-Package Microsoft.AspNet.WebPages.Data

You should probably do a clean build before attempting any of the answers to this question and after updating packages

You can also do the following;

string json = myJObject.ToString(Newtonsoft.Json.Formatting.None);

The solution from CSS-Tricks no longer works in jQuery 2.2.0. It will throw a selector error:

JavaScript runtime error: Syntax error, unrecognized expression: a[href*=#]:not([href=#])

I fixed it by changing the selector. The full snippet is this:

$(function() {
  $("a[href*='#']:not([href='#'])").click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
    var target = $(this.hash);
    target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
    if (target.length) {
      $('html,body').animate({
        scrollTop: target.offset().top
      }, 1000);
      return false;
    }
  }
 });
});

The jsonify() function in flask returns a flask.Response() object that already has the appropriate content-type header 'application/json' for use with json responses. Whereas, the json.dumps() method will just return an encoded string, which would require manually adding the MIME type header.

See more about the jsonify() function here for full reference.

Edit: Also, I've noticed that jsonify() handles kwargs or dictionaries, while json.dumps() additionally supports lists and others.

First try:

net stop MySQL   
net start MySQL

If that does not work, try using the windows interface:

Start > Control Panel > System and Security > Administrative Tools > Services

Look for your version of MySQL (In my case - MySQL55), highlight and click the green start arrow. The status should change to "Started"

Border doesn't support percentage... but it's still possible...

As others have pointed to CSS specification, percentages aren't supported on borders:

'border-top-width',
'border-right-width',
'border-bottom-width',
'border-left-width'
  Value:          <border-width> | inherit
  Initial:        medium
  Applies to:     all elements
  Inherited:      no
  Percentages:    N/A
  Media:          visual
  Computed value: absolute length; '0' if the border style is 'none' or 'hidden'

As you can see it says Percentages: N/A.

Non-scripted solution

You can simulate your percentage borders with a wrapper element where you would:

1. set wrapper element's background-color to your desired border colour
2. set wrapper element's padding in percentages (because they're supported)
3. set your elements background-color to white (or whatever it needs to be)

This would somehow simulate your percentage borders. Here's an example of an element with 25% width side borders that uses this technique.

HTML used in the example

.faux-borders {_x000D_
    background-color: #f00;_x000D_
    padding: 1px 25%; /* set padding to simulate border */_x000D_
}_x000D_
.content {_x000D_
    background-color: #fff;_x000D_
}

<div class="faux-borders">_x000D_
    <div class="content">_x000D_
        This is the element to have percentage borders._x000D_
    </div>_x000D_
</div>

Issue: You have to be aware that this will be much more complicated when your element has some complex background applied to it... Especially if that background is inherited from ancestor DOM hierarchy. But if your UI is simple enough, you can do it this way.

Scripted solution

@BoltClock mentioned scripted solution where you can programmaticaly calculate border width according to element size.

This is such an example with extremely simple script using jQuery.

var el = $(".content");_x000D_
var w = el.width() / 4 | 0; // calculate & trim decimals_x000D_
el.css("border-width", "1px " + w + "px");

.content { border: 1px solid #f00; }

<div class="content">_x000D_
    This is the element to have percentage borders._x000D_
</div>

But you have to be aware that you will have to adjust border width every time your container size changes (i.e. browser window resize). My first workaround with wrapper element seems much simpler because it will automatically adjust width in these situations.

The positive side of scripted solution is that it doesn't suffer from background problems mentioned in my previous non-scripted solution.

You can use tidy application/utility to indent HTML & XML files and it works pretty well in indenting those files.

Prettify an XML file

:!tidy -mi -xml %

Prettify an HTML file

:!tidy -mi -html %

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

Add this to your project: https://requirejs.org/docs/release/2.3.5/minified/require.js

and take a look at this http://requirejs.org/docs/api.html

elif and else must immediately follow the end of the if block, or Python will assume that the block has closed without them.

if 1:
    pass
             <--- this line must be indented at the same level as the `pass`
else:
    pass

In your code, the interpreter finishes the if block when the indentation, so the elif and the else aren't associated with it. They are thus being understood as standalone statements, which doesn't make sense.

In general, try to follow the style guidelines, which include removing excessive whitespace.

string var = "12345678";

if (var.Length >= 4)
{
    var = var.substring(var.Length - 4, 4)
}

// result = "5678"

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.

The easiest way is to have a "wrapper" div element with a width set, and a left and right margin of auto.

Sample markup:

<!doctype html>
<html>
<head>
    <title></title>
    <style type="text/css">
        .wrapper { width: 960px; margin: 0 auto; background-color: #cccccc; }
        body { margin: 0; padding: 0 }
    </style>
</head>
<body>
    <div class="wrapper">
        your content...
    </div>
</body>
</html>

If you want more alternatives, You can try installing a Modern command line HTTP client like httpie which is available for most of the Operating Systems with package managers like brew, apt-get, pip, yum etc

eg:- For OSX

brew install httpie

Then you can use it on command line with various options

http GET https://www.google.com

Try this

df.drop(df.iloc[:, 1:69], inplace=True, axis=1)

This works for me

Get a list of files with Python 2 and 3

os.listdir() - list in the current directory

With listdir in os module you get the files and the folders in the current dir

 import os
 arr = os.listdir()
 print(arr)
 
 >>> ['$RECYCLE.BIN', 'work.txt', '3ebooks.txt', 'documents']

Python 2

You need the ''

 arr = os.listdir('')

Looking in a directory

arr = os.listdir('c:\\files')

glob from glob

with glob you can specify a type of file to list like this

import glob

txtfiles = []
for file in glob.glob("*.txt"):
    txtfiles.append(file)

glob im a list comprehension

mylist = [f for f in glob.glob("*.txt")]

Getting the full path name with os.path.abspath

You get the full path in return

 import os
 files_path = [os.path.abspath(x) for x in os.listdir()]
 print(files_path)
 
 >>> ['F:\\documenti\applications.txt', 'F:\\documenti\collections.txt']

Walk: going through sub directories

os.walk returns the root, the directories list and the files list, that is why I unpacked them in r, d, f in the for loop; it, then, looks for other files and directories in the subfolders of the root and so on until there are no subfolders.

import os

# Getting the current work directory (cwd)
thisdir = os.getcwd()

# r=root, d=directories, f = files
for r, d, f in os.walk(thisdir):
    for file in f:
        if file.endswith(".docx"):
            print(os.path.join(r, file))

os.listdir(): get files in the current directory (Python 2)

In Python 2, if you want the list of the files in the current directory, you have to give the argument as '.' or os.getcwd() in the os.listdir method.

 import os
 arr = os.listdir('.')
 print(arr)
 
 >>> ['$RECYCLE.BIN', 'work.txt', '3ebooks.txt', 'documents']

To go up in the directory tree

# Method 1
x = os.listdir('..')

# Method 2
x= os.listdir('/')

Get files: os.listdir() in a particular directory (Python 2 and 3)

 import os
 arr = os.listdir('F:\\python')
 print(arr)
 
 >>> ['$RECYCLE.BIN', 'work.txt', '3ebooks.txt', 'documents']

Get files of a particular subdirectory with os.listdir()

import os

x = os.listdir("./content")

os.walk('.') - current directory

 import os
 arr = next(os.walk('.'))[2]
 print(arr)
 
 >>> ['5bs_Turismo1.pdf', '5bs_Turismo1.pptx', 'esperienza.txt']

next(os.walk('.')) and os.path.join('dir', 'file')

 import os
 arr = []
 for d,r,f in next(os.walk("F:\\_python")):
     for file in f:
         arr.append(os.path.join(r,file))

 for f in arr:
     print(files)

>>> F:\\_python\\dict_class.py
>>> F:\\_python\\programmi.txt

next(os.walk('F:\\') - get the full path - list comprehension

 [os.path.join(r,file) for r,d,f in next(os.walk("F:\\_python")) for file in f]
 
 >>> ['F:\\_python\\dict_class.py', 'F:\\_python\\programmi.txt']

os.walk - get full path - all files in sub dirs**

x = [os.path.join(r,file) for r,d,f in os.walk("F:\\_python") for file in f]
print(x)

>>> ['F:\\_python\\dict.py', 'F:\\_python\\progr.txt', 'F:\\_python\\readl.py']

os.listdir() - get only txt files

 arr_txt = [x for x in os.listdir() if x.endswith(".txt")]
 print(arr_txt)
 
 >>> ['work.txt', '3ebooks.txt']

Using glob to get the full path of the files

If I should need the absolute path of the files:

from path import path
from glob import glob
x = [path(f).abspath() for f in glob("F:\\*.txt")]
for f in x:
    print(f)

>>> F:\acquistionline.txt
>>> F:\acquisti_2018.txt
>>> F:\bootstrap_jquery_ecc.txt

Using os.path.isfile to avoid directories in the list

import os.path
listOfFiles = [f for f in os.listdir() if os.path.isfile(f)]
print(listOfFiles)

>>> ['a simple game.py', 'data.txt', 'decorator.py']

Using pathlib from Python 3.4

import pathlib

flist = []
for p in pathlib.Path('.').iterdir():
    if p.is_file():
        print(p)
        flist.append(p)

 >>> error.PNG
 >>> exemaker.bat
 >>> guiprova.mp3
 >>> setup.py
 >>> speak_gui2.py
 >>> thumb.PNG

With list comprehension:

flist = [p for p in pathlib.Path('.').iterdir() if p.is_file()]

Alternatively, use pathlib.Path() instead of pathlib.Path(".")

Use glob method in pathlib.Path()

import pathlib

py = pathlib.Path().glob("*.py")
for file in py:
    print(file)

>>> stack_overflow_list.py
>>> stack_overflow_list_tkinter.py

Get all and only files with os.walk

import os
x = [i[2] for i in os.walk('.')]
y=[]
for t in x:
    for f in t:
        y.append(f)
print(y)

>>> ['append_to_list.py', 'data.txt', 'data1.txt', 'data2.txt', 'data_180617', 'os_walk.py', 'READ2.py', 'read_data.py', 'somma_defaltdic.py', 'substitute_words.py', 'sum_data.py', 'data.txt', 'data1.txt', 'data_180617']

Get only files with next and walk in a directory

 import os
 x = next(os.walk('F://python'))[2]
 print(x)
 
 >>> ['calculator.bat','calculator.py']

Get only directories with next and walk in a directory

 import os
 next(os.walk('F://python'))[1] # for the current dir use ('.')
 
 >>> ['python3','others']

Get all the subdir names with walk

for r,d,f in os.walk("F:\\_python"):
    for dirs in d:
        print(dirs)

>>> .vscode
>>> pyexcel
>>> pyschool.py
>>> subtitles
>>> _metaprogramming
>>> .ipynb_checkpoints

os.scandir() from Python 3.5 and greater

import os
x = [f.name for f in os.scandir() if f.is_file()]
print(x)

>>> ['calculator.bat','calculator.py']

# Another example with scandir (a little variation from docs.python.org)
# This one is more efficient than os.listdir.
# In this case, it shows the files only in the current directory
# where the script is executed.

import os
with os.scandir() as i:
    for entry in i:
        if entry.is_file():
            print(entry.name)

>>> ebookmaker.py
>>> error.PNG
>>> exemaker.bat
>>> guiprova.mp3
>>> setup.py
>>> speakgui4.py
>>> speak_gui2.py
>>> speak_gui3.py
>>> thumb.PNG

Examples:

Ex. 1: How many files are there in the subdirectories?

In this example, we look for the number of files that are included in all the directory and its subdirectories.

import os

def count(dir, counter=0):
    "returns number of files in dir and subdirs"
    for pack in os.walk(dir):
        for f in pack[2]:
            counter += 1
    return dir + " : " + str(counter) + "files"

print(count("F:\\python"))

>>> 'F:\\\python' : 12057 files'

Ex.2: How to copy all files from a directory to another?

A script to make order in your computer finding all files of a type (default: pptx) and copying them in a new folder.

import os
import shutil
from path import path

destination = "F:\\file_copied"
# os.makedirs(destination)

def copyfile(dir, filetype='pptx', counter=0):
    "Searches for pptx (or other - pptx is the default) files and copies them"
    for pack in os.walk(dir):
        for f in pack[2]:
            if f.endswith(filetype):
                fullpath = pack[0] + "\\" + f
                print(fullpath)
                shutil.copy(fullpath, destination)
                counter += 1
    if counter > 0:
        print('-' * 30)
        print("\t==> Found in: `" + dir + "` : " + str(counter) + " files\n")

for dir in os.listdir():
    "searches for folders that starts with `_`"
    if dir[0] == '_':
        # copyfile(dir, filetype='pdf')
        copyfile(dir, filetype='txt')


>>> _compiti18\Compito Contabilità 1\conti.txt
>>> _compiti18\Compito Contabilità 1\modula4.txt
>>> _compiti18\Compito Contabilità 1\moduloa4.txt
>>> ------------------------
>>> ==> Found in: `_compiti18` : 3 files

Ex. 3: How to get all the files in a txt file

In case you want to create a txt file with all the file names:

import os
mylist = ""
with open("filelist.txt", "w", encoding="utf-8") as file:
    for eachfile in os.listdir():
        mylist += eachfile + "\n"
    file.write(mylist)

Example: txt with all the files of an hard drive

"""
We are going to save a txt file with all the files in your directory.
We will use the function walk()
"""

import os

# see all the methods of os
# print(*dir(os), sep=", ")
listafile = []
percorso = []
with open("lista_file.txt", "w", encoding='utf-8') as testo:
    for root, dirs, files in os.walk("D:\\"):
        for file in files:
            listafile.append(file)
            percorso.append(root + "\\" + file)
            testo.write(file + "\n")
listafile.sort()
print("N. of files", len(listafile))
with open("lista_file_ordinata.txt", "w", encoding="utf-8") as testo_ordinato:
    for file in listafile:
        testo_ordinato.write(file + "\n")

with open("percorso.txt", "w", encoding="utf-8") as file_percorso:
    for file in percorso:
        file_percorso.write(file + "\n")

os.system("lista_file.txt")
os.system("lista_file_ordinata.txt")
os.system("percorso.txt")

All the file of C:\ in one text file

This is a shorter version of the previous code. Change the folder where to start finding the files if you need to start from another position. This code generate a 50 mb on text file on my computer with something less then 500.000 lines with files with the complete path.

import os

with open("file.txt", "w", encoding="utf-8") as filewrite:
    for r, d, f in os.walk("C:\\"):
        for file in f:
            filewrite.write(f"{r + file}\n")

How to write a file with all paths in a folder of a type

With this function you can create a txt file that will have the name of a type of file that you look for (ex. pngfile.txt) with all the full path of all the files of that type. It can be useful sometimes, I think.

import os

def searchfiles(extension='.ttf', folder='H:\\'):
    "Create a txt file with all the file of a type"
    with open(extension[1:] + "file.txt", "w", encoding="utf-8") as filewrite:
        for r, d, f in os.walk(folder):
            for file in f:
                if file.endswith(extension):
                    filewrite.write(f"{r + file}\n")

# looking for png file (fonts) in the hard disk H:\
searchfiles('.png', 'H:\\')

>>> H:\4bs_18\Dolphins5.png
>>> H:\4bs_18\Dolphins6.png
>>> H:\4bs_18\Dolphins7.png
>>> H:\5_18\marketing html\assets\imageslogo2.png
>>> H:\7z001.png
>>> H:\7z002.png

(New) Find all files and open them with tkinter GUI

I just wanted to add in this 2019 a little app to search for all files in a dir and be able to open them by doubleclicking on the name of the file in the list.

import tkinter as tk
import os

def searchfiles(extension='.txt', folder='H:\\'):
    "insert all files in the listbox"
    for r, d, f in os.walk(folder):
        for file in f:
            if file.endswith(extension):
                lb.insert(0, r + "\\" + file)

def open_file():
    os.startfile(lb.get(lb.curselection()[0]))

root = tk.Tk()
root.geometry("400x400")
bt = tk.Button(root, text="Search", command=lambda:searchfiles('.png', 'H:\\'))
bt.pack()
lb = tk.Listbox(root)
lb.pack(fill="both", expand=1)
lb.bind("<Double-Button>", lambda x: open_file())
root.mainloop()

It tells the compiler that you're in a Single Thread Apartment model. This is an evil COM thing, it's usually used for Windows Forms (GUI's) as that uses Win32 for its drawing, which is implemented as STA. If you are using something that's STA model from multiple threads then you get corrupted objects.

This is why you have to invoke onto the Gui from another thread (if you've done any forms coding).

Basically don't worry about it, just accept that Windows GUI threads must be marked as STA otherwise weird stuff happens.

You can use pd.to_datetime() to convert to a datetime object. It takes a format parameter, but in your case I don't think you need it.

>>> import pandas as pd
>>> df = pd.DataFrame( {'Symbol':['A','A','A'] ,
    'Date':['02/20/2015','01/15/2016','08/21/2015']})
>>> df
         Date Symbol
0  02/20/2015      A
1  01/15/2016      A
2  08/21/2015      A
>>> df['Date'] =pd.to_datetime(df.Date)
>>> df.sort('Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

For future search, you can change the sort statement:

>>> df.sort_values(by='Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

It made sense to me that clicking the X should count as a change event. I already had the onChange event all setup to do what I needed it to do. So for me, the fix was to simply do this jQuery line:

$('#search').click(function(){ $(this).change(); });

You could use viewport-percentage lenghts.

See: http://stanhub.com/how-to-make-div-element-100-height-of-browser-window-using-css-only/

It works like this:

.element{
    height: 100vh; /* For 100% screen height */
    width:  100vw; /* For 100% screen width */
}

More info also available through Mozilla Developer Network and W3C.

From Web Application I think you can't, but you can rename all the folders in Git Client, it will move your files in the new renamed folders, than commit and push to remote repository.

I had a very similar issue: I had to rename different folders from uppercase to lowercase (like Abc -> abc), I've renamed all the folders with a dummy name (like 'abc___') and than committed to remote repository, after that I renamed all the folders to the original name with the lowercase (like abc) and it took them!

I also found that it failed when I tried to load the XIB with a name like @"MyFile.xib". When I just used @"MyFile" it worked - apparently it always adds the extension. But the error message just said it couldn't find MyFIle.xib in the bundle - if it had said MyFile.xib.xib, that would have been a big clue.

Replace version code with appropriate code of library version will solve your issue, like this:

 <integer name="google_play_services_version"> <versioncode> </integer>

If you already have the content you want to write to the file (and not generated on the fly), the java.nio.file.Files addition in Java 7 as part of native I/O provides the simplest and most efficient way to achieve your goals.

Basically creating and writing to a file is one line only, moreover one simple method call!

The following example creates and writes to 6 different files to showcase how it can be used:

Charset utf8 = StandardCharsets.UTF_8;
List<String> lines = Arrays.asList("1st line", "2nd line");
byte[] data = {1, 2, 3, 4, 5};

try {
    Files.write(Paths.get("file1.bin"), data);
    Files.write(Paths.get("file2.bin"), data,
            StandardOpenOption.CREATE, StandardOpenOption.APPEND);
    Files.write(Paths.get("file3.txt"), "content".getBytes());
    Files.write(Paths.get("file4.txt"), "content".getBytes(utf8));
    Files.write(Paths.get("file5.txt"), lines, utf8);
    Files.write(Paths.get("file6.txt"), lines, utf8,
            StandardOpenOption.CREATE, StandardOpenOption.APPEND);
} catch (IOException e) {
    e.printStackTrace();
}

Reading a local word list

If you're doing this repeatedly, I would download it locally and pull from the local file. *nix users can use /usr/share/dict/words.

Example:

word_file = "/usr/share/dict/words"
WORDS = open(word_file).read().splitlines()

Pulling from a remote dictionary

If you want to pull from a remote dictionary, here are a couple of ways. The requests library makes this really easy (you'll have to pip install requests):

import requests

word_site = "https://www.mit.edu/~ecprice/wordlist.10000"

response = requests.get(word_site)
WORDS = response.content.splitlines()

Alternatively, you can use the built in urllib2.

import urllib2

word_site = "https://www.mit.edu/~ecprice/wordlist.10000"

response = urllib2.urlopen(word_site)
txt = response.read()
WORDS = txt.splitlines()

One more (idio(ma)tic) way:

URL.split("/")[-1]

To create a read-only user, you have to setup a different user than the one owning the tables you want to access.

If you just create the user and grant SELECT permission to the read-only user, you'll need to prepend the schema name to each table name. To avoid this, you have basically two options:

1. Set the current schema in your session:

ALTER SESSION SET CURRENT_SCHEMA=XYZ

2. Create synonyms for all tables:

CREATE SYNONYM READER_USER.TABLE1 FOR XYZ.TABLE1

So if you haven't been told the name of the owner schema, you basically have three options. The last one should always work:

1. Query the current schema setting:

SELECT SYS_CONTEXT('USERENV','CURRENT_SCHEMA') FROM DUAL

2. List your synonyms:

SELECT * FROM ALL_SYNONYMS WHERE OWNER = USER

3. Investigate all tables (with the exception of the some well-known standard schemas):

SELECT * FROM ALL_TABLES WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'CTXSYS', 'MDSYS');

In Python 3.6 you can use so called f-strings. In my opinion this method is much clearer to read.

>>> f'{a:02d}'
'05'

In general, you're better off validating URLs using built-in library or framework functions, rather than rolling your own regular expressions to do this - see What is the best regular expression to check if a string is a valid URL for details.

If you are keen on doing this, though, check out this question:

Getting parts of a URL (Regex)

Then, once you're satisfied with the URL (by whatever means you used to validate it), you could either use a simple "endswith" type string operator to check the extension, or a simple regex like

(?i)\.(jpg|png|gif)$

You may want to use:

SELECT Name, 'Unpaid' AS Status FROM table;

The SELECT clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:

SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ] 
<select_list> 

Where the expression can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.

Variable number of arguments

It is possible to pass a variable number of arguments to a method. However, there are some restrictions:

• The variable number of parameters must all be the same type
• They are treated as an array within the method
• They must be the last parameter of the method

To understand these restrictions, consider the method, in the following code snippet, used to return the largest integer in a list of integers:

private static int largest(int... numbers) {
     int currentLargest = numbers[0];
     for (int number : numbers) {
        if (number > currentLargest) {
            currentLargest = number;
        }
     }
     return currentLargest;
}

Instead of using a Dictionary, why not convert to an ILookup?

var myData = new[]{new {a=1,b="frog"}, new {a=1,b="cat"}, new {a=2,b="giraffe"}};
ILookup<int,string> lookup = myData.ToLookup(x => x.a, x => x.b);
IEnumerable<string> allOnes = lookup[1]; //enumerable of 2 items, frog and cat

An ILookup is an immutable data structure that allows multiple values per key. Probably not much use if you need to add items at different times, but if you have all your data up-front, this is definitely the way to go.

This kind of code perhaps should work for You

You can also dynamically create a class by using DynamicObject.

public class DynamicClass : DynamicObject
{
    private Dictionary<string, KeyValuePair<Type, object>> _fields;

    public DynamicClass(List<Field> fields)
    {
        _fields = new Dictionary<string, KeyValuePair<Type, object>>();
        fields.ForEach(x => _fields.Add(x.FieldName,
            new KeyValuePair<Type, object>(x.FieldType, null)));
    }

    public override bool TrySetMember(SetMemberBinder binder, object value)
    {
        if (_fields.ContainsKey(binder.Name))
        {
            var type = _fields[binder.Name].Key;
            if (value.GetType() == type)
            {
                _fields[binder.Name] = new KeyValuePair<Type, object>(type, value);
                return true;
            }
            else throw new Exception("Value " + value + " is not of type " + type.Name);
        }
        return false;
    }

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        result = _fields[binder.Name].Value;
        return true;
    }
}

I store all class fields in a dictionary _fields together with their types and values. The both methods are to can get or set value to some of the properties. You must use the dynamic keyword to create an instance of this class.

The usage with your example:

var fields = new List<Field>() { 
    new Field("EmployeeID", typeof(int)),
    new Field("EmployeeName", typeof(string)),
    new Field("Designation", typeof(string)) 
};

dynamic obj = new DynamicClass(fields);

//set
obj.EmployeeID = 123456;
obj.EmployeeName = "John";
obj.Designation = "Tech Lead";

obj.Age = 25;             //Exception: DynamicClass does not contain a definition for 'Age'
obj.EmployeeName = 666;   //Exception: Value 666 is not of type String

//get
Console.WriteLine(obj.EmployeeID);     //123456
Console.WriteLine(obj.EmployeeName);   //John
Console.WriteLine(obj.Designation);    //Tech Lead

Edit: And here is how looks my class Field:

public class Field
{
    public Field(string name, Type type)
    {
        this.FieldName = name;
        this.FieldType = type;
    }

    public string FieldName;

    public Type FieldType;
}

You are using .index() which will only find the first occurrence of your value in the list. So if you have a value 1.0 at index 2, and at index 9, then .index(1.0) will always return 2, no matter how many times 1.0 occurs in the list.

Use enumerate() to add indices to your loop instead:

def find(lst, a, b):
    result = []
    for i, x in enumerate(lst):
        if x<a or x>b:
            result.append(i)
    return result

You can collapse this into a list comprehension:

def find(lst, a, b):
    return [i for i, x in enumerate(lst) if x<a or x>b]

Option 1: Likely fastest (but not supported by some browsers if used on Document or SVGElement) :

var elements = document.getElementById('parentContainer').children;

Option 2: Likely slowest :

var elements = document.getElementById('parentContainer').getElementsByTagName('*');

Option 3: Requires change to code (wrap a form instead of a div around it) :

// Since what you're doing looks like it should be in a form...
var elements = document.forms['parentContainer'].elements;

var matches = [];

for (var i = 0; i < elements.length; i++)
    if (elements[i].value.indexOf('q17_') == 0)
        matches.push(elements[i]);

// Sorts an array of objects "in place". (Meaning that the original array will be modified and nothing gets returned.)
function sortOn (arr, prop) {
    arr.sort (
        function (a, b) {
            if (a[prop] < b[prop]){
                return -1;
            } else if (a[prop] > b[prop]){
                return 1;
            } else {
                return 0;   
            }
        }
    );
}

//Usage example:

var cars = [
        {make:"AMC",        model:"Pacer",  year:1978},
        {make:"Koenigsegg", model:"CCGT",   year:2011},
        {make:"Pagani",     model:"Zonda",  year:2006},
        ];

// ------- make -------
sortOn(cars, "make");
console.log(cars);

/* OUTPUT:
AMC         : Pacer : 1978
Koenigsegg  : CCGT  : 2011
Pagani      : Zonda : 2006
*/



// ------- model -------
sortOn(cars, "model");
console.log(cars);

/* OUTPUT:
Koenigsegg  : CCGT  : 2011
AMC         : Pacer : 1978
Pagani      : Zonda : 2006
*/



// ------- year -------
sortOn(cars, "year");
console.log(cars);

/* OUTPUT:
AMC         : Pacer : 1978
Pagani      : Zonda : 2006
Koenigsegg  : CCGT  : 2011
*/

The best solution is <input ... size={input.value.length} />

You can use TEXT type, which is not limited to 64KB.

FYI, I put together a JSFiddle of this using the $cookieStore, two controllers, a $rootScope, and AngularjS 1.0.6. It's on JSFifddle as http://jsfiddle.net/krimple/9dSb2/ as a base if you're messing around with this...

The gist of it is:

Javascript

var myApp = angular.module('myApp', ['ngCookies']);

myApp.controller('CookieCtrl', function ($scope, $rootScope, $cookieStore) {
    $scope.bump = function () {
        var lastVal = $cookieStore.get('lastValue');
        if (!lastVal) {
            $rootScope.lastVal = 1;
        } else {
            $rootScope.lastVal = lastVal + 1;
        }
        $cookieStore.put('lastValue', $rootScope.lastVal);
    }
});

myApp.controller('ShowerCtrl', function () {
});

HTML

<div ng-app="myApp">
    <div id="lastVal" ng-controller="ShowerCtrl">{{ lastVal }}</div>
    <div id="button-holder" ng-controller="CookieCtrl">
        <button ng-click="bump()">Bump!</button>
    </div>
</div>

Starting simple, with no HTML:

foreach($database as $file) {
    echo $file['filename'] . ' at ' . $file['filepath'];
}

And you can otherwise manipulate the fields in the foreach.

Just leaving this here for future visitors:

In my case the /WEB-INF/classes directory was missing. If you are using Eclipse, make sure the .settings/org.eclipse.wst.common.component is correct (Deployment Assembly in the project settings).

In my case it was missing

    <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>
    <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/test/resources"/>

This file is also a common source of errors as mentioned by Anuj (missing dependencies of other projects).

Otherwise, hopefully the other answers (or the "Problems" tab) will help you.

It is important to define an id in the model

.DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Model(model => model.Id(p => p.id))
    )

There are several options... assuming you found your TD by var td = document.getElementyById('myTD_ID'); you can do:

• td.innerHTML = "mytext";

• td.textContent= "mytext";

• td.innerText= "mytext"; - this one may not work outside IE? Not sure

• Use firstChild or children array as previous poster noted.

If it's just the text that needs to be changed, textContent is faster and less prone to XSS attacks (https://developer.mozilla.org/en-US/docs/Web/API/Node.textContent)

I use intellj idea and in windows in terminal type: gradlew.bat run it is working for me.

The use of IDE is your personal preference. But personally if I had to choose, Eclipse is a widely known, trusted and certainly offers more features then Android Studio. Android Studio is a little new right now. May be it's upcoming versions keep up to Eclipse level soon.

"editor.formatOnType": true

When you enter the semicolon, it's going to be formatted.

Alternatively, you can also use "editor.formatOnSave": true.

I think that you will have to go for your last solution, scraping the result page of the search, because you can only search by email with the API into those users that have authorized your APP (and you will need one because the token that FB provides in the examples has an expiry date and you need extended permissions to access the user's email).

The only approach that I have not tried, but I think it's limited in the same way, is FQL. Something like

SELECT * FROM user WHERE email '[email protected]'

You don't say if this is a desktop or web app. I would use the getResourceAsStream() method from an appropriate ClassLoader if it's a desktop or the Context if it's a web app.

For MacOS Mojave:

gem install mysql2 -v '0.5.2' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include

Try to change all the persmissions at the same time:

chmod -R +xr

You can do this in any program other than Explorer, e.g. Notepad, cmd.exe etc.

You just can't do it in Explorer, and Raymond Chen has offered an explanation as to why not.
