C strings are not anything like Java strings. They're essentially arrays of characters.

You are getting the error because strToLower returns a char. A char is a form of integer in C. You are assigning it into a char[] which is a pointer. Hence "converting integer to pointer".

Your strToLower makes all its changes in place, there is no reason for it to return anything, especially not a char. You should "return" void, or a char*.

On the call to strToLower, there is also no need for assignment, you are essentially just passing the memory address for cString1.

In my experience, Strings in C are the hardest part to learn for anyone coming from Java/C# background back to C. People can get along with memory allocation (since even in Java you often allocate arrays). If your eventual goal is C++ and not C, you may prefer to focus less on C strings, make sure you understand the basics, and just use the C++ string from STL.

It is also very important to distinguish a SENDING multicast socket from a RECEIVING multicast socket.

I agree with all the answers above regarding RECEIVING multicast sockets. The OP noted that binding a RECEIVING socket to an interface did not help. However, it is necessary to bind a multicast SENDING socket to an interface.

For a SENDING multicast socket on a multi-homed server, it is very important to create a separate socket for each interface you want to send to. A bound SENDING socket should be created for each interface.

  // This is a fix for that bug that causes Servers to pop offline/online.
  // Servers will intermittently pop offline/online for 10 seconds or so.
  // The bug only happens if the machine had a DHCP gateway, and the gateway is no longer accessible.
  // After several minutes, the route to the DHCP gateway may timeout, at which
  // point the pingponging stops.
  // You need 3 machines, Client machine, server A, and server B
  // Client has both ethernets connected, and both ethernets receiving CITP pings (machine A pinging to en0, machine B pinging to en1)
  // Now turn off the ping from machine B (en1), but leave the network connected.
  // You will notice that the machine transmitting on the interface with
  // the DHCP gateway will fail sendto() with errno 'No route to host'
  if ( theErr == 0 )
  {
     // inspired by 'ping -b' option in man page:      
     //      -b boundif
     //             Bind the socket to interface boundif for sending.
     struct sockaddr_in bindInterfaceAddr;
     bzero(&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     bindInterfaceAddr.sin_len = sizeof(bindInterfaceAddr);
     bindInterfaceAddr.sin_family = AF_INET;
     bindInterfaceAddr.sin_addr.s_addr = htonl(interfaceipaddr);
     bindInterfaceAddr.sin_port = 0; // Allow the kernel to choose a random port number by passing in 0 for the port.
     theErr = bind(mSendSocketID, (struct sockaddr *)&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     struct sockaddr_in serverAddress;
     int namelen = sizeof(serverAddress);  
     if (getsockname(mSendSocketID, (struct sockaddr *)&serverAddress, (socklen_t *)&namelen) < 0) {
        DLogErr(@"ERROR Publishing service... getsockname err");
     }
     else
     {
        DLog( @"socket %d bind, %@ port %d", mSendSocketID, [NSString stringFromIPAddress:htonl(serverAddress.sin_addr.s_addr)], htons(serverAddress.sin_port) );
     }

Without this fix, multicast sending will intermittently get sendto() errno 'No route to host'. If anyone can shed light on why unplugging a DHCP gateway causes Mac OS X multicast SENDING sockets to get confused, I would love to hear it.

You don't need to ALTER any table. Just use the following queries, prior to the actual SELECT query that you want to use the wildcard:

    set names `utf8`;
    SET COLLATION_CONNECTION=utf8_general_ci;
    SET CHARACTER_SET_CLIENT=utf8;
    SET CHARACTER_SET_RESULTS=utf8;

I'd try something like:

#!/usr/bin/python
from __future__ import print_function

import shlex
from subprocess import Popen, PIPE

def shlep(cmd):
    '''shlex split and popen
    '''
    parsed_cmd = shlex.split(cmd)
    ## if parsed_cmd[0] not in approved_commands:
    ##    raise ValueError, "Bad User!  No output for you!"
    proc = Popen(parsed_command, stdout=PIPE, stderr=PIPE)
    out, err = proc.communicate()
    return (proc.returncode, out, err)

... In other words let shlex.split() do most of the work. I would NOT attempt to parse the shell's command line, find pipe operators and set up your own pipeline. If you're going to do that then you'll basically have to write a complete shell syntax parser and you'll end up doing an awful lot of plumbing.

Of course this raises the question, why not just use Popen with the shell=True (keyword) option? This will let you pass a string (no splitting nor parsing) to the shell and still gather up the results to handle as you wish. My example here won't process any pipelines, backticks, file descriptor redirection, etc that might be in the command, they'll all appear as literal arguments to the command. Thus it is still safer then running with shell=True ... I've given a silly example of checking the command against some sort of "approved command" dictionary or set --- through it would make more sense to normalize that into an absolute path unless you intend to require that the arguments be normalized prior to passing the command string to this function.

   <p id="text" onclick="func()">
    Click on text to change
</p>
<script>
function func()
{
    document.getElementById("text").style.color="red";
    document.getElementById("text").style.font="calibri";
}
</script>

To find the keycode for any key, use this simple function:

document.onkeydown = function(evt) {
    console.log(evt.keyCode);
}

There is a way without flexbox, although you'd need to meet the following conditions. 1) The container has padding. 2) Items are the same size and you know exactly how many you want per line.

ul {
  padding: 0 3% 0 5%;
}
li {
  display: inline-block; 
  padding: 0 2% 2% 0;
  width: 28.66%;
}

The smaller padding on the right side of the container allows for the extra padding to the right of each list item. Assuming other items in the same parent as the list object are padded with 0 5%, it will be flush with them. You can also adjust the percentages to however much margin you'd like or use calculate px values.

Of course, you can do the same without the padding on the container by using nth-child (IE 9+) to remove margin on every third box.

Try wrapping the spans in an anchor tag and apply the background image to that.

HTML:

<div class="header">
    <a href="/">
        <span class="header-title">My gray sea design</span><br />
        <span class="header-title-two">A beautiful design</span>
    </a>
</div>

CSS:

.header {
    border-bottom:1px solid #eaeaea;
}

.header a {
    display: block;
    background-image: url("./images/embouchure.jpg");
    background-repeat: no-repeat;
    height:160px;
    padding-left:280px;
    padding-top:50px;
    width:470px;
    color: #eaeaea;
}

Similar to the answer before there there is

location.host

The location global has more fun facts about the current url as well. ( protocol, host, port, pathname, search, hash )

eval() is very powerful and can be used to execute a JS statement or evaluate an expression. But the question isn't about the uses of eval() but lets just say some how the string you running with eval() is affected by a malicious party. At the end you will be running malicious code. With power comes great responsibility. So use it wisely is you are using it. This isn't related much to eval() function but this article has pretty good information: http://blogs.popart.com/2009/07/javascript-injection-attacks/ If you are looking for the basics of eval() look here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval

Working code in jsfiddle due to some security issue of stackoverflow: http://jsfiddle.net/k2vwqoyp/

Most solutions here tell you how to use a placeholder integer to represent nulls. That approach isn't helpful if you're uncertain that integer won't show up in your source data though. My method with will format floats without their decimal values and convert nulls to None's. The result is an object datatype that will look like an integer field with null values when loaded into a CSV.

keep_df[col] = keep_df[col].apply(lambda x: None if pandas.isnull(x) else '{0:.0f}'.format(pandas.to_numeric(x)))

It normally represents a parameter to be supplied by client.

file = open('parsed_data.txt', 'w')
for link in soup.findAll('a', attrs={'href': re.compile("^http")}): print (link)
soup_link = str(link)
print (soup_link)
file.write(soup_link)
file.flush()
file.close()

In my case, I used BeautifulSoup to write a .txt with Python 3.x. It had the same issue. Just as @tsduteba said, change the 'wb' in the first line to 'w'.

If you have to do a curl in php, you should use urlencode() from PHP but individually!

strPOST = "Item1=" . $Value1 . "&Item2=" . urlencode("+")

If you do urlencode(strPOST), you will bring you another problem, you will have one Item1 and & will be change %xx value and be as one value, see down here the return!

Example 1

$strPOST = "Item1=" . $Value1 . "&Item2=" . urlencode("+") will give Item1=Value1&Item2=%2B

Example 2

$strPOST = urlencode("Item1=" . $Value1 . "&Item2=+") will give Item1%3DValue1%26Item2%3D%2B

Example 1 is the good way to prepare string for POST in curl

Example 2 show that the receptor will not see the equal and the ampersand to distinguish both value!

There are two ways to do it.

1. In the method that opens the dialog, pass in the following configuration option disableClose as the second parameter in MatDialog#open() and set it to true:

   export class AppComponent {
     constructor(private dialog: MatDialog){}
     openDialog() {
       this.dialog.open(DialogComponent, { disableClose: true });
     }
   }
   

2. Alternatively, do it in the dialog component itself.

   export class DialogComponent {
     constructor(private dialogRef: MatDialogRef<DialogComponent>){
       dialogRef.disableClose = true;
     }
   }
   

Here's what you're looking for:

And here's a Stackblitz demo

Other use cases

Here's some other use cases and code snippets of how to implement them.

Allow esc to close the dialog but disallow clicking on the backdrop to close the dialog

As what @MarcBrazeau said in the comment below my answer, you can allow the esc key to close the modal but still disallow clicking outside the modal. Use this code on your dialog component:

import { Component, OnInit, HostListener } from '@angular/core';
import { MatDialogRef } from '@angular/material';
@Component({
  selector: 'app-third-dialog',
  templateUrl: './third-dialog.component.html'
})
export class ThirdDialogComponent {
  constructor(private dialogRef: MatDialogRef<ThirdDialogComponent>) {      
}
  @HostListener('window:keyup.esc') onKeyUp() {
    this.dialogRef.close();
  }

}

Prevent esc from closing the dialog but allow clicking on the backdrop to close

P.S. This is an answer which originated from this answer, where the demo was based on this answer.

To prevent the esc key from closing the dialog but allow clicking on the backdrop to close, I've adapted Marc's answer, as well as using MatDialogRef#backdropClick to listen for click events to the backdrop.

Initially, the dialog will have the configuration option disableClose set as true. This ensures that the esc keypress, as well as clicking on the backdrop will not cause the dialog to close.

Afterwards, subscribe to the MatDialogRef#backdropClick method (which emits when the backdrop gets clicked and returns as a MouseEvent).

Anyways, enough technical talk. Here's the code:

openDialog() {
  let dialogRef = this.dialog.open(DialogComponent, { disableClose: true });
  /*
     Subscribe to events emitted when the backdrop is clicked
     NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
     See https://stackoverflow.com/a/41086381 for more info
  */
  dialogRef.backdropClick().subscribe(() => {
    // Close the dialog
    dialogRef.close();
  })

  // ...
}

Alternatively, this can be done in the dialog component:

export class DialogComponent {
  constructor(private dialogRef: MatDialogRef<DialogComponent>) {
    dialogRef.disableClose = true;
    /*
      Subscribe to events emitted when the backdrop is clicked
      NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
      See https://stackoverflow.com/a/41086381 for more info
    */
    dialogRef.backdropClick().subscribe(() => {
      // Close the dialog
      dialogRef.close();
    })
  }
}

Another example, more simple than some others with simple return of incremented value:

function testIncrement1(x) {
    return x++;
}

function testIncrement2(x) {
    return ++x;
}

function testIncrement3(x) {
    return x += 1;
}

console.log(testIncrement1(0)); // 0
console.log(testIncrement2(0)); // 1
console.log(testIncrement3(0)); // 1

As you can see, no post-increment/decrement should be used at return statement, if you want this operator to influence the result. But return doesn't "catch" post-increment/decrement operators:

function closureIncrementTest() {
    var x = 0;

    function postIncrementX() {
        return x++;
    }

    var y = postIncrementX();

    console.log(x); // 1
}

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonInclude(JsonInclude.Include.NON_EMPTY)

should work.

Include.NON_EMPTY indicates that property is serialized if its value is not null and not empty. Include.NON_NULL indicates that property is serialized if its value is not null.

While this is based on the sterling answers elsewhere on this page, I had a use case which wasn't completely solved by them; for a vector of pointers to functions do the following:

#include <iostream>
#include <vector>
#include <stdio.h>
#include <stdlib.h>

class A{
public:
  typedef vector<int> (A::*AFunc)(int I1,int I2);
  vector<AFunc> FuncList;
  inline int Subtract(int I1,int I2){return I1-I2;};
  inline int Add(int I1,int I2){return I1+I2;};
  ...
  void Populate();
  void ExecuteAll();
};

void A::Populate(){
    FuncList.push_back(&A::Subtract);
    FuncList.push_back(&A::Add);
    ...
}

void A::ExecuteAll(){
  int In1=1,In2=2,Out=0;
  for(size_t FuncId=0;FuncId<FuncList.size();FuncId++){
    Out=(this->*FuncList[FuncId])(In1,In2);
    printf("Function %ld output %d\n",FuncId,Out);
  }
}

int main(){
  A Demo;
  Demo.Populate();
  Demo.ExecuteAll();
  return 0;
}

Something like this is useful if you are writing a command interpreter with indexed functions that need to be married up with parameter syntax and help tips etc. Possibly also useful in menus.

No need to use select just use [ instead

data[,grepl("search_string", colnames(data))]

Let's try with iris dataset

>iris[,grepl("Sepal", colnames(iris))]
  Sepal.Length Sepal.Width
1          5.1         3.5
2          4.9         3.0
3          4.7         3.2
4          4.6         3.1
5          5.0         3.6
6          5.4         3.9

Try

echo getenv('COMPUTERNAME');

This will return your computername.

Although I've used the accepted answer in the past, it seems with the current Build Tools it is possible to do:

   <dimen name="listAvatarWidthPercent">0.19</dimen>

I'm using Build Tools major version 29.

On CentOS this worked for me:

echo "email body" | mail -s "Subject here" -r from_email_address email_address_to

Alexander Pavlov's answer gets the closest to what you want.

Due to the extensiveness of jQuery's abstraction and functionality, a lot of hoops have to be jumped in order to get to the meat of the event. I have set up this jsFiddle to demonstrate the work.

1. Setting up the Event Listener Breakpoint

You were close on this one.

1. Open the Chrome Dev Tools (F12), and go to the Sources tab.
2. Drill down to Mouse -> Click
   
   (click to zoom)

2. Click the button!

Chrome Dev Tools will pause script execution, and present you with this beautiful entanglement of minified code:

(click to zoom)

3. Find the glorious code!

Now, the trick here is to not get carried away pressing the key, and keep an eye out on the screen.

1. Press the F11 key (Step In) until desired source code appears
2. Source code finally reached
   • In the jsFiddle sample provided above, I had to press F11 108 times before reaching the desired event handler/function
   • Your mileage may vary, depending on the version of jQuery (or framework library) used to bind the events
   • With enough dedication and time, you can find any event handler/function

4. Explanation

I don't have the exact answer, or explanation as to why jQuery goes through the many layers of abstractions it does - all I can suggest is that it is because of the job it does to abstract away its usage from the browser executing the code.

Here is a jsFiddle with a debug version of jQuery (i.e., not minified). When you look at the code on the first (non-minified) breakpoint, you can see that the code is handling many things:

    // ...snip...

    if ( !(eventHandle = elemData.handle) ) {
        eventHandle = elemData.handle = function( e ) {
            // Discard the second event of a jQuery.event.trigger() and
            // when an event is called after a page has unloaded
            return typeof jQuery !== strundefined && jQuery.event.triggered !== e.type ?
                jQuery.event.dispatch.apply( elem, arguments ) : undefined;
        };
    }

    // ...snip...

The reason I think you missed it on your attempt when the "execution pauses and I jump line by line", is because you may have used the "Step Over" function, instead of Step In. Here is a StackOverflow answer explaining the differences.

Finally, the reason why your function is not directly bound to the click event handler is because jQuery returns a function that gets bound. jQuery's function in turn goes through some abstraction layers and checks, and somewhere in there, it executes your function.

There are a variety of ways to get the URL .m3u8 either by viewing the source of a page, looking at the Network tab in the Developer Tools in Chrome, or using a plugin such as HDL/HLS Video Downloader.

With the .m3u8 URL in hand you can then use ffmpeg to download the video to a file like so:

$ ffmpeg -i 'https://url/to/some/file.m3u8' -bsf:a aac_adtstoasc \
    -vcodec copy -c copy -crf 50 file.mp4

I had exactly the same issue, after moving from old go version (installed from old PPA) to newer (1.2.1) default packages in ubuntu 14.04.

The first step was to purge existing go:

sudo apt-get purge golang*

Which outputs following warnings:

dpkg: warning: while removing golang-go, directory '/usr/lib/go/src' not empty so not removed
dpkg: warning: while removing golang-go.tools, directory '/usr/lib/go' not empty so not removed

It looks like removing go leaves some files behind, which in turn can confuse newer install. More precisely, installation itself will complete fine, but afterwards any go command, like "go get something" gives those "unrecognized import path" errors.

All I had to do was to remove those dirs first, reinstall golang, and all works like a charm (assuming you also set GOPATH)

# careful!
sudo rm -rf /usr/lib/go /usr/lib/go/src
sudo apt-get install golang-go golang-go.tools

The config file is just an XML file, you can open it by:

private static XmlDocument loadConfigDocument()
{
    XmlDocument doc = null;
    try
    {
        doc = new XmlDocument();
        doc.Load(getConfigFilePath());
        return doc;
    }
    catch (System.IO.FileNotFoundException e)
    {
        throw new Exception("No configuration file found.", e);
    }
    catch (Exception ex)
    {
        return null;
    }
}

and later retrieving values by:

    // retrieve appSettings node

    XmlNode node =  doc.SelectSingleNode("//appSettings");

I'll suggest that you use this as it will check for both single and multiple occurrence of white space (as suggested by Lucas Green).

$journalName = preg_replace('/\s+/', '_', $journalName);

instead of:

$journalName = str_replace(' ', '_', $journalName);

seems the Ctrl+Break doesn't work on me, neither the Preference - User...

use keys, Alt ? t ? c

My big issue here was to build the Object structure required to match RestTemplate to a compatible Class. Luckily I found http://www.jsonschema2pojo.org/ (get the JSON response in a browser and use it as input) and I can't recommend this enough!

If you already have all the required modules installed you probably need to import the setuptools module in your setup.py file. So just add the following line at the leading of setup.py file.

import setuptools
from distutils.core import setup
# other imports and setups

This is also mentioned in wheel's documentation. https://wheel.readthedocs.io/en/stable/#usage

Here is my solution need get Status Http for checking status of server regularly

$url = 'http://www.example.com'; // Your server link

while(true) {

    $strHeader = get_headers($url)[0];

    $statusCode = substr($strHeader, 9, 3 );

    if($statusCode != 200 ) {
        echo 'Server down.';
        // Send email 
    }
    else {
        echo 'oK';
    }

    sleep(30);
}

The SetCursorPosition method works in multi-threading scenario, where the other two methods don't

Just thinking about it from a speed issue I believe the case sensitive example provided in the link above would be by far the fastest solution.

var token = "\r\n";
var newToken = " ";
var oldStr = "This is a test\r\nof the emergency broadcasting\r\nsystem.";
newStr = oldStr.split(token).join(newToken);

newStr would be "This is a test of the emergency broadcast system."

You can use the standard HTML title attribute of image for this:

<img src="source of image" alt="alternative text" title="this will be displayed as a tooltip"/>

Have you activated your environment? Also you could try this: vscode select venv

As Tim Potter pointed out, setting proxy in dockerfile is horrible. When building the image, you add proxy for your corporate network but you may be deploying in cloud or a DMZ where there is no need for proxy or the proxy server is different.

Also, you cannot share your image with others outside your corporate n/w.

It exits the function and returns nothing.

Something like return 1; would be incorrect since it returns integer 1.

If you want to keep it simple go ahead and try this out.

$page_number = mysqli_escape_string($con, $_GET['page']);
$count_per_page = 20;
$next_offset = $page_number * $count_per_page;
$cat =mysqli_query($con, "SELECT * FROM categories LIMIT $count_per_page OFFSET $next_offset");
while ($row = mysqli_fetch_array($cat))
        $count = $row[0];

The rest is up to you. If you have result comming from two tables i suggest you try a different approach.

You can open an image using the Image class from the package PIL and display it with plt.imshow directly.

# First import libraries.
from PIL import Image
import matplotlib.pyplot as plt

# The folliwing line is useful in Jupyter notebook
%matplotlib inline

# Open your file image using the path
img = Image.open(<path_to_image>)

# Since plt knows how to handle instance of the Image class, just input your loaded image to imshow method
plt.imshow(img)

You do not even need lists if your "number" values are all of the same mode. If I take Dirk Eddelbuettel's example:

> foo <- c(12, 22, 33)
> names(foo) <- c("tic", "tac", "toe")
> foo
tic tac toe
 12  22  33
> names(foo)
[1] "tic" "tac" "toe"

Lists are only required if your values are either of mixed mode (for example characters and numbers) or vectors.

For both lists and vectors, an individual element can be subsetted by name:

> foo["tac"]
tac 
 22 

Or for a list:

> foo[["tac"]]
[1] 22

Include the HTML

Including HTML is done by using a w3-include-html attribute:

Example

    <div w3-include-html="content.html"></div>

Add the JavaScript

HTML includes are done by JavaScript.

    <script>
    function includeHTML() {
      var z, i, elmnt, file, xhttp;
      /*loop through a collection of all HTML elements:*/
      z = document.getElementsByTagName("*");
      for (i = 0; i < z.length; i++) {
        elmnt = z[i];
        /*search for elements with a certain atrribute:*/
        file = elmnt.getAttribute("w3-include-html");
        if (file) {
          /*make an HTTP request using the attribute value as the file name:*/
          xhttp = new XMLHttpRequest();
          xhttp.onreadystatechange = function() {
            if (this.readyState == 4) {
              if (this.status == 200) {elmnt.innerHTML = this.responseText;}
              if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
              /*remove the attribute, and call this function once more:*/
              elmnt.removeAttribute("w3-include-html");
              includeHTML();
            }
          } 
          xhttp.open("GET", file, true);
          xhttp.send();
          /*exit the function:*/
          return;
        }
      }
    }
    </script>

Call includeHTML() at the bottom of the page:

Example

<!DOCTYPE html>
<html>
<script>
function includeHTML() {
  var z, i, elmnt, file, xhttp;
  /*loop through a collection of all HTML elements:*/
  z = document.getElementsByTagName("*");
  for (i = 0; i < z.length; i++) {
    elmnt = z[i];
    /*search for elements with a certain atrribute:*/
    file = elmnt.getAttribute("w3-include-html");
    if (file) {
      /*make an HTTP request using the attribute value as the file name:*/
      xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
        if (this.readyState == 4) {
          if (this.status == 200) {elmnt.innerHTML = this.responseText;}
          if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
          /*remove the attribute, and call this function once more:*/
          elmnt.removeAttribute("w3-include-html");
          includeHTML();
        }
      }      
      xhttp.open("GET", file, true);
      xhttp.send();
      /*exit the function:*/
      return;
    }
  }
};
</script>
<body>

<div w3-include-html="h1.html"></div> 
<div w3-include-html="content.html"></div> 

<script>
includeHTML();
</script>

I had the same issue with a site which previously was running fine. I resolved the issue by deleting the temporary files from C:\WINDOWS\Microsoft.NET\Framework\v#.#.#####\Temporary ASP.NET Files\@projectName\###CC##C\###C#CC

Simply do :

int index = List.FindIndex(your condition);

E.g.

int index = cars.FindIndex(c => c.ID == 150);

Just download "node.exe" from http://nodejs.org/dist/, select your favorite "node.js" version or take the latest. You can also take 64-bits version from "x64" sub-directory.

Then, go to http://nodejs.org/dist/npm/ to retrieve Zip-archive of your favorite "npm" version (recommanded : 1.4.10). Extract the archive along "node.exe".

Finally, it is recommanded to add "node.js" directory to the PATH for convenience.

EDIT: I recommande to update npm using npm install npm -g because versions provided by nodejs.org are very old.

If you want to keep original npm version, don't put npm alongside "node.exe". Just create a directory and use the same command with "global" flag, then copy .\node_modules\.bin\npm.cmd to the new directory :

mkdir c:\app\npm\_latest
cd c:\app\npm\_latest
<NPM_ORIGINAL_PATH>\npm install npm
cp node_modules\.bin\npm.cmd npm.cmd

Finally change your PATH to use c:\app\npm\_latest

I haven't seen this anywhere, either, but my instinct would be that this means that the IF prevented the whole statement from executing.

Try to run the statement with a database where the IF passes.

Also check if there are any triggers involved which might change the result.

[EDIT] When the standard says that this function should never return -1, that doesn't enforce this. Java doesn't have pre and post conditions. A JDBC driver could return a random number and there was no way to stop it.

If it's important to know why this happens, run the statement against different database until you have tried all execution paths (i.e. one where the IF returns false and one where it returns true).

If it's not that important, mark it off as a "clever trick" by a Microsoft engineer and remember how much you liked it when you feel like being clever yourself next time.

find . -type f -name "*.xls" -printf "xls2csv %p %p.csv\n" | bash

If you don't have a page which is accessing the websocket, you can open up the Chrome console and type your JavaScript in:

var webSocket = new WebSocket('ws://address:port');
webSocket.onmessage = function(data) { console.log(data); }

This will open up the web socket so you can see it in the network tab and in the console.

TL;DR

In the first case with set encoding=utf-8, you'll change the output encoding that is shown in the terminal.

In the second case with set fileencoding=utf-8, you'll change the output encoding of the file that is written.

As stated by @Dennis, you can set them both in your ~/.vimrc if you always want to work in utf-8.

More details

From the wiki of VIM about working with unicode

"encoding sets how vim shall represent characters internally. Utf-8 is necessary for most flavors of Unicode."

"fileencoding sets the encoding for a particular file (local to buffer); :setglobal sets the default value. An empty value can also be used: it defaults to same as 'encoding'. Or you may want to set one of the ucs encodings, It might make the same disk file bigger or smaller depending on your particular mix of characters. Also, IIUC, utf-8 is always big-endian (high bit first) while ucs can be big-endian or little-endian, so if you use it, you will probably need to set 'bomb" (see below)."

As per the documentation you can add comments only at the time of creating table. So it is must to have table definition. One way to automate it using the script to read the definition and update your comments.

Reference:

http://bugs.mysql.com/bug.php?id=64439

You can write following codes to achieve this task:

SELECT ... FROM ... WHERE ... 
INTO OUTFILE 'textfile.csv'
FIELDS TERMINATED BY '|'

It export the result to CSV and then export it to excel sheet.

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans

POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.

That doesn't work because, judging by the rest of the code, the initial value of the text input is "Default text" - which is more than one character, and so your if condition is always true.

The simplest way to make it work, it seems to me, is to account for this case:

    var value = $(this).val();
    if ( value.length > 0 && value != "Default text" ) ...

var $div = $('#desiredDiv');
$div.contents().remove();
$div.html('<p>This is new HTML.</p>');

That should work just fine.

Just re-posting answer by oleynikd because it's simple and neat

Bundle bundle = ActivityOptionsCompat.makeCustomAnimation(getContext(),
    android.R.anim.fade_in, android.R.anim.fade_out).toBundle(); 
startActivity(intent, bundle);

Follow the below steps to avoid (cannot convert between unicode and non-unicode string data types) this error

i) Add the Data conversion Transformation tool to your DataFlow.
ii) To open the DataFlow Conversion and select [string DT_STR] datatype.
iii) Then go to Destination flow, select Mapping.
iv) change your i/p name to copy of the name.

You can always do this:

jQuery.fn.extend({
   myfunction: function(param){
       // code here
   },
});
OR
jQuery.extend({
   myfunction: function(param){
       // code here
   },
});
$(element).myfunction(param);

Necromancing:

It's relativiely simple to emulate a COUNT DISTINCT over PARTITION BY with MAX via DENSE_RANK:

;WITH baseTable AS
(
    SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR3' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR2' AS ADR
)
,CTE AS
(
    SELECT RM, ADR, DENSE_RANK() OVER(PARTITION BY RM ORDER BY ADR) AS dr 
    FROM baseTable
)
SELECT
     RM
    ,ADR

    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY ADR) AS cnt1 
    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM) AS cnt2 
    -- Not supported
    --,COUNT(DISTINCT CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY CTE.ADR) AS cntDist
    ,MAX(CTE.dr) OVER (PARTITION BY CTE.RM ORDER BY CTE.RM) AS cntDistEmu 
FROM CTE

Note:
This assumes the fields in question are NON-nullable fields.
If there is one or more NULL-entries in the fields, you need to subtract 1.

My guess would be that while you run eclipse itself with JDK 1.6, it's actually configured with a different default jre.

See Window->preferences->java->Installed JREs and make sure that the checked JRE is 1.6.

If the default JRE is indeed 1.6, chances are that it's a project specific setting. See that the project is configured to use the right JRE.

For single-page sites where the menu items simply jump down to other sections of the page, this simple solution works for me:

$('.nav li').on('click', function(){
    $('.nav li').removeClass('active');
    $(this).addClass('active');
  });

Set these styles to image component: { textAlignVertical: "center", textAlign: "center" }

After having the same problem as you and doing some reading, I discovered the solution - Pack URIs.

I did the following in code:

Image finalImage = new Image();
finalImage.Width = 80;
...
BitmapImage logo = new BitmapImage();
logo.BeginInit();
logo.UriSource = new Uri("pack://application:,,,/AssemblyName;component/Resources/logo.png");
logo.EndInit();
...
finalImage.Source = logo;

Or shorter, by using another BitmapImage constructor:

finalImage.Source = new BitmapImage(
    new Uri("pack://application:,,,/AssemblyName;component/Resources/logo.png"));

The URI is broken out into parts:

• Authority: application:///

• Path: The name of a resource file that is compiled into a referenced assembly. The path must conform to the following format: AssemblyShortName[;Version][;PublicKey];component/Path

  • AssemblyShortName: the short name for the referenced assembly.
  • ;Version [optional]: the version of the referenced assembly that contains the resource file. This is used when two or more referenced assemblies with the same short name are loaded.
  • ;PublicKey [optional]: the public key that was used to sign the referenced assembly. This is used when two or more referenced assemblies with the same short name are loaded.
  • ;component: specifies that the assembly being referred to is referenced from the local assembly.
  • /Path: the name of the resource file, including its path, relative to the root of the referenced assembly's project folder.

The three slashes after application: have to be replaced with commas:

Note: The authority component of a pack URI is an embedded URI that points to a package and must conform to RFC 2396. Additionally, the "/" character must be replaced with the "," character, and reserved characters such as "%" and "?" must be escaped. See the OPC for details.

And of course, make sure you set the build action on your image to Resource.

You can easily do with first you can make the div flex and apply justify content right or left and your problem is solved.

<div style="display: flex;padding-bottom: 8px;justify-content: flex-end;">_x000D_
     <button style="font-weight: bold;outline: none;background-color: #2764ff;border-radius: 3px;margin-left: 12px;border: none;padding: 3px 6px;color: white;text-align: center;font-family: 'Open Sans', sans-serif;text-decoration: none;margin-right: 14px;">Sense</button>_x000D_
    </div>

There is currently a problem with R12 where the SDK location cannot contain any spaces.

The default installation location is: C:\Programme Files(x86)\Android\android-sdk. They are currently fixing the problem but you can currently work around it by changing the SDK location path in eclipse to C:\PROGRA~2\Android\android-sdk.

If you are running 32-bit Windows, change the path to C:\PROGRA~1\Android\android-sdk.

user Jochen Ritzel said this in a comment to an answer to this question from user dappawit. It should work:

('1' in var) and ('2' in var) and ('3' in var) ...

'1', '2', etc. should be replaced with the characters you are looking for.

See this page in the Python 2.7 documentation for some information on strings, including about using the in operator for substring tests.

Update: This does the same job as my above suggestion with less repetition:

# When looking for single characters, this checks for any of the characters...
# ...since strings are collections of characters
any(i in '<string>' for i in '123')
# any(i in 'a' for i in '123') -> False
# any(i in 'b3' for i in '123') -> True

# And when looking for subsrings
any(i in '<string>' for i in ('11','22','33'))
# any(i in 'hello' for i in ('18','36','613')) -> False
# any(i in '613 mitzvahs' for i in ('18','36','613')) ->True

Alternatively, I think it is worth mentioning that the behavior of equals and compareTo methods in the class BigDecimal are not consistent with each other.

This basically means that:

BigDecimal someValue = new BigDecimal("0.00");
System.out.println(someValue.compareTo(BigDecimal.ZERO) == 0); // true
System.out.println(someValue.equals(BigDecimal.ZERO)); // false

Therefore, you have to be very careful with the scale in your someValue variable, otherwise you would get unexpected result.

If you don't need the exact size of the object but roughly to know how big it is, one quick (and dirty) way is to let the program run, sleep for an extended period of time, and check the memory usage (ex: Mac's activity monitor) by this particular python process. This would be effective when you are trying to find the size of one single large object in a python process. For example, I recently wanted to check the memory usage of a new data structure and compare it with that of Python's set data structure. First I wrote the elements (words from a large public domain book) to a set, then checked the size of the process, and then did the same thing with the other data structure. I found out the Python process with a set is taking twice as much memory as the new data structure. Again, you wouldn't be able to exactly say the memory used by the process is equal to the size of the object. As the size of the object gets large, this becomes close as the memory consumed by the rest of the process becomes negligible compared to the size of the object you are trying to monitor.

another example:

Reading file one row at the time. Removing unwanted chars with from end of the string str.rstrip(chars)

with open(filename, 'r') as fileobj:
    for row in fileobj:
        print( row.rstrip('\n') )

There is now a "native" solution on Windows 10, after enabling Bash on Windows, you can enter Bash shell by typing bash:

You can run Bash script like bash ./script.sh, but keep in mind that C drive is located at /mnt/c, and external hard drives are not mountable. So you might need to change your script a bit so it is compatible to Windows.

Also, even as root, you can still get permission denied when moving files around in /mnt, but you have your full root power in the / file system.

Also make sure your shell script is formatted with Unix style, or there can be errors.

@Value("${your.elements}")    
private String[] elements;

yml file:

your:
 elements: element1, element2, element3

You could put your items into a set. Set lookups are very efficient.

Try:

s = set(a)
if 7 in s:
  # do stuff

edit In a comment you say that you'd like to get the index of the element. Unfortunately, sets have no notion of element position. An alternative is to pre-sort your list and then use binary search every time you need to find an element.

Not sure what isn't working in your case, but the following code will put a formula into cell A1 that will retrieve the value in the cell G2.

strProjectName = "Sheet1"
Cells(1, 1).Formula = "=" & strProjectName & "!" & Cells(2, 7).Address

The workbook and worksheet that strProjectName references must exist at the time that this formula is placed. Excel will immediately try to evaluate the formula. You might be able to stop that from happening by turning off automatic recalculation until the workbook does exist.

You can use inline styles to add custome styling to <option> tags.

For eg : <option style="font-weight:bold;color:#09C;">Option 1</option> This will apply the styles to this particular <option> element only.

Then you can use a bit of javascript magic to apply the inline styles to all of the <option> elements within a <select> tag like so :

var select = $(document).getElementById('#select-element-id')

var option = select.children('#option-element-id')

option.css('font-weight', 'bold')

option.css('font-size', '24px')

You can also use <option value="" disabled> <br> </option> to add a line-break between the options.

I guess you can use:

$con = new mysqli("localhost", "my_user", "my_password", "world");
$sql = "UPDATE `some_table` SET `txid`= '$txid', `data` = '$data' WHERE `wallet` = '$wallet'";
if ($mysqli->query($sql, $con)) {
    print "wallet $wallet updated";
}else{
    printf("Errormessage: %s\n", $con->error);
}
$con->close();

Add to your activity theme, item colorControlActivated, for example:

    <style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
            ...
            <item name="colorControlActivated">@color/rocket_black</item>
            ...
    </style>

Apply this style to your Activity in the manifest:

<activity
    android:name=".packege.YourActivity"
    android:theme="@style/AppTheme.NoActionBar"/>

WARNING: Don't use crypto or pycrypto anymore!

As you can read on this page, the usage of pycrypto is not safe anymore:

Pycrypto is vulnerable to a heap-based buffer overflow in the ALGnew function in block_templace.c. It allows remote attackers to execute arbitrary code in the python application. It was assigned the CVE-2013-7459 number.

Pycrypto didn’t release any fix to that vulnerability and no commit was made to the project since Jun 20, 2014.

Update 2021-01-18: The CVE is fixed now (thanks @SumitBadsara for pointing it out!). You can find the current status of the open security tickets for each package at the Debian security tracker:

• python-crypto
• pycryptodome

Use Python3's pycryptodome instead!

Make sure to uninstall all versions of crypto and pycrypto first, then install pycryptodome:

pip3 uninstall crypto 
pip3 uninstall pycrypto 
pip3 install pycryptodome

All of these three packages get installed to the same folder, named Crypto. Installing different packages under the same folder name can be a common source for errors!

Best practice: virtual environments

In order to avoid problems with pip packages in different versions or packages that install under the same folder (i.e. pycrypto and pycryptodome) you can make use of a so called virtual environment. There, the installed pip packages can be managed for every single project individually.

To install a virtual environment and setup everything, use the following commands:

# install python3 and pip3
sudo apt update
sudo apt upgrade
sudo apt install python3
sudo apt install python3-pip

# install virtualenv
pip3 install virtualenv

# install and create a virtual environment in your target folder
mkdir target_folder
cd target_folder
python3 -m virtualenv .

# now activate your venv and install pycryptodome
source bin/activate
pip3 install pycryptodome

# check if everything worked: 
# start the interactive python console and import the Crypto module
# when there is no import error then it worked
python
>>> from Crypto.Cipher import AES
>>> exit()

# don't forget to deactivate your venv again
deactivate

A lot has been said previously, but back to the roots, in a more technical way:

1. IEnumerable is a collection of objects in memory that you can enumerate - an in-memory sequence that makes it possible to iterate through (makes it way easy for within foreach loop, though you can go with IEnumerator only). They reside in the memory as is.
2. IQueryable is an expression tree that will get translated into something else at some point with ability to enumerate over the final outcome. I guess this is what confuses most people.

They obviously have different connotations.

IQueryable represents an expression tree (a query, simply) that will be translated to something else by the underlying query provider as soon as release APIs are called, like LINQ aggregate functions (Sum, Count, etc.) or ToList[Array, Dictionary,...]. And IQueryable objects also implement IEnumerable, IEnumerable<T> so that if they represent a query the result of that query could be iterated. It means IQueryable don't have to be queries only. The right term is they are expression trees.

Now how those expressions are executed and what they turn to is all up to so called query providers (expression executors we can think them of).

In the Entity Framework world (which is that mystical underlying data source provider, or the query provider) IQueryable expressions are translated into native T-SQL queries. Nhibernate does similar things with them. You can write your own one following the concepts pretty well described in LINQ: Building an IQueryable Provider link, for example, and you might want to have a custom querying API for your product store provider service.

So basically, IQueryable objects are getting constructed all the way long until we explicitly release them and tell the system to rewrite them into SQL or whatever and send down the execution chain for onward processing.

As if to deferred execution it's a LINQ feature to hold up the expression tree scheme in the memory and send it into the execution only on demand, whenever certain APIs are called against the sequence (the same Count, ToList, etc.).

The proper usage of both heavily depends on the tasks you're facing for the specific case. For the well-known repository pattern I personally opt for returning IList, that is IEnumerable over Lists (indexers and the like). So it is my advice to use IQueryable only within repositories and IEnumerable anywhere else in the code. Not saying about the testability concerns that IQueryable breaks down and ruins the separation of concerns principle. If you return an expression from within repositories consumers may play with the persistence layer as they would wish.

A little addition to the mess :) (from a discussion in the comments)) None of them are objects in memory since they're not real types per se, they're markers of a type - if you want to go that deep. But it makes sense (and that's why even MSDN put it this way) to think of IEnumerables as in-memory collections whereas IQueryables as expression trees. The point is that the IQueryable interface inherits the IEnumerable interface so that if it represents a query, the results of that query can be enumerated. Enumeration causes the expression tree associated with an IQueryable object to be executed. So, in fact, you can't really call any IEnumerable member without having the object in the memory. It will get in there if you do, anyways, if it's not empty. IQueryables are just queries, not the data.

In my opinion [] and {} are the most pythonic and readable ways to create empty lists/dicts.

Be wary of set()'s though, for example:

this_set = {5}
some_other_set = {}

Can be confusing. The first creates a set with one element, the second creates an empty dict and not a set.

simple way:

let's say you have db.js file in a helpers directory in project structure.

now go inside helpers directory and go to node console

 helpers $ node

2) require db.js file

> var db = require("./db")

3) call your function (in your case its init())

> db.init()

hope this helps

You can simulate pointers to instantiated objects to some degree:

class pointer {
   var $child;

   function pointer(&$child) {
       $this->child = $child;
   }

   public function __call($name, $arguments) {
       return call_user_func_array(
           array($this->child, $name), $arguments);
   }
}

Use like this:

$a = new ClassA();

$p = new pointer($a);

If you pass $p around, it will behave like a C++ pointer regarding method calls (you can't touch object variables directly, but that's evil anyways :) ).

I also had this problem, but I made a workaround using a ImageView.

Try using a RelativeLayout and add a ImageView inside it (width and height: fill_parent, scaleType: center).

Also make sure the imageview is the first element inside the RelativeLayout, so it will act as background.

Neither one is better in that they may be used for different purposes. onClick (should actually be onclick) performs very slightly better, but I highly doubt you will notice a difference there.

It is worth noting that they do different things: .click can be bound to any jQuery collection whereas onclick has to be used inline on the elements you want it to be bound to. You can also bind only one event to using onclick, whereas .click lets you continue to bind events.

In my opinion, I would be consistent about it and just use .click everywhere and keep all of my JavaScript code together and separated from the HTML.

Don't use onclick. There isn't any reason to use it unless you know what you're doing, and you probably don't.

If you want a command-line solution, I suggest to just go with MBO's answer.

If you're a newbie, you might like the graphical approach:

1. Kick off gitk (from the command line, or right click in file browser if you have that)
2. You can easily spot the merge commit there - the first node from the top with two parents
3. Follow the link to the first/left parent (the one on your current branch before the merge, usually red for me)
4. On the selected commit, right-click "Reset branch to here", pick the hard reset there

Following icza's wonderfully explained solution, here is a modification of it that uses crypto/rand instead of math/rand.

const (
    letterBytes = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ" // 52 possibilities
    letterIdxBits = 6                    // 6 bits to represent 64 possibilities / indexes
    letterIdxMask = 1<<letterIdxBits - 1 // All 1-bits, as many as letterIdxBits
)

func SecureRandomAlphaString(length int) string {

    result := make([]byte, length)
    bufferSize := int(float64(length)*1.3)
    for i, j, randomBytes := 0, 0, []byte{}; i < length; j++ {
        if j%bufferSize == 0 {
            randomBytes = SecureRandomBytes(bufferSize)
        }
        if idx := int(randomBytes[j%length] & letterIdxMask); idx < len(letterBytes) {
            result[i] = letterBytes[idx]
            i++
        }
    }

    return string(result)
}

// SecureRandomBytes returns the requested number of bytes using crypto/rand
func SecureRandomBytes(length int) []byte {
    var randomBytes = make([]byte, length)
    _, err := rand.Read(randomBytes)
    if err != nil {
        log.Fatal("Unable to generate random bytes")
    }
    return randomBytes
}

If you want a more generic solution, that allows you to pass in the slice of character bytes to create the string out of, you can try using this:

// SecureRandomString returns a string of the requested length,
// made from the byte characters provided (only ASCII allowed).
// Uses crypto/rand for security. Will panic if len(availableCharBytes) > 256.
func SecureRandomString(availableCharBytes string, length int) string {

    // Compute bitMask
    availableCharLength := len(availableCharBytes)
    if availableCharLength == 0 || availableCharLength > 256 {
        panic("availableCharBytes length must be greater than 0 and less than or equal to 256")
    }
    var bitLength byte
    var bitMask byte
    for bits := availableCharLength - 1; bits != 0; {
        bits = bits >> 1
        bitLength++
    }
    bitMask = 1<<bitLength - 1

    // Compute bufferSize
    bufferSize := length + length / 3

    // Create random string
    result := make([]byte, length)
    for i, j, randomBytes := 0, 0, []byte{}; i < length; j++ {
        if j%bufferSize == 0 {
            // Random byte buffer is empty, get a new one
            randomBytes = SecureRandomBytes(bufferSize)
        }
        // Mask bytes to get an index into the character slice
        if idx := int(randomBytes[j%length] & bitMask); idx < availableCharLength {
            result[i] = availableCharBytes[idx]
            i++
        }
    }

    return string(result)
}

If you want to pass in your own source of randomness, it would be trivial to modify the above to accept an io.Reader instead of using crypto/rand.

Seems to be a common Windows problem. This fixed it for me:

Nodejs cannot find installed module on Windows?

"Add an environment variable called NODE_PATH and set it to %USERPROFILE%\Application Data\npm\node_modules (Windows XP), %AppData%\npm\node_modules (Windows 7), or wherever npm ends up installing the modules on your Windows flavor. To be done with it once and for all, add this as a System variable in the Advanced tab of the System Properties dialog (run control.exe sysdm.cpl,System,3)."

Note that you can't actually use another environment variable within the value of NODE_PATH. That is, don't just copy and paste that string above, but set it to an actual resolved path like C:\Users\MYNAME\AppData\Roaming\npm\node_modules

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using
End Sub

You use ttk.Frame, bg option does not work for it. You should create style and apply it to the frame.

from tkinter import *
from tkinter.ttk import * 

root = Tk()

s = Style()
s.configure('My.TFrame', background='red')

mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()

I have tried to run same program using eclipse and it shows clear difference between memcpy and memmove. memcpy() doesn't care about overlapping of memory location which results in corruption of data, while memmove() will copy data to temporary variable first and then copy into actual memory location.

While trying to copy data from location str1 to str1+2, output of memcpy is "aaaaaa". The question would be how? memcpy() will copy one byte at a time from left to right. As shown in your program "aabbcc" then all copying will take place as below,

1. aabbcc -> aaabcc

2. aaabcc -> aaaacc

3. aaaacc -> aaaaac

4. aaaaac -> aaaaaa

memmove() will copy data to temporary variable first and then copy to actual memory location.

1. aabbcc(actual) -> aabbcc(temp)

2. aabbcc(temp) -> aaabcc(act)

3. aabbcc(temp) -> aaaacc(act)

4. aabbcc(temp) -> aaaabc(act)

5. aabbcc(temp) -> aaaabb(act)

Output is

memcpy : aaaaaa

memmove : aaaabb

To apply to an entire list, use

ul.space_list li { margin-bottom: 1em; }

Then, in the html:

<ul class=space_list>
<li>A</li>
<li>B</li>
</ul>

firstarray and secondarray are converted to a pointer to int, when passed to printarray().

printarray(int arg[], ...) is equivalent to printarray(int *arg, ...)

However, this is not specific to C++. C has the same rules for passing array names to a function.

I was looking to do the same thing, and I have a work around that seems to be less complicated using the Frequency and Index functions. I use this part of the function from averaging over multiple sheets while excluding the all the 0's.

=(FREQUENCY(Start:End!B1,-0.000001)+INDEX(FREQUENCY(Start:End!B1,0),2))

Code generation would be the only other way I can think of. Personally, I'd got with a generally reusable reflection solution (unless that part of the code is absolutely performance-critical). Using JMS sounds like overkill (additional dependency, and that's not even what it's meant for). Besides, it probably uses reflection as well under the hood.

This is a function for calculating max valid length for varchar(Nn):

CREATE FUNCTION [dbo].[GetMaxVarcharColumnLength] (@TableSchema NVARCHAR(MAX), @TableName NVARCHAR(MAX), @ColumnName VARCHAR(MAX))
RETURNS INT
AS
BEGIN
    RETURN (SELECT character_maximum_length FROM information_schema.columns  
            WHERE table_schema = @TableSchema AND table_name = @TableName AND column_name = @ColumnName);
END

Usage:

IF LEN(@Name) > [dbo].[GetMaxVarcharColumnLength]('person', 'FamilyStateName', 'Name') 
            RETURN [dbo].[err_Internal_StringForVarcharTooLong]();

The solution is very simple, but took me about 2 hours and half the hair on my head to find it.

Simply wrap your content with a (redundant) div that has display: none and Bob is your uncle.

As per machineAddict's comment, as of version 2 and later, year, month and day have been replaced by defaultDate, which is a Moment, supporting constructors such as an ISO 8601 date string or a Unix Epoch.

So e.g. to initialize the calendar with a given date:

$('#calendar').fullCalendar({
    defaultDate: moment('2014-09-01'),
    ...
});

The reason is that the Scanner class is designed for reading in whitespace-separated tokens. It's a convenience class that wraps an underlying input stream. Before scanner all you could do was read in single bytes, and that's a big pain if you want to read words or lines. With Scanner you pass in System.in, and it does a number of read() operations to tokenize the input for you. Reading a single character is a more basic operation. Source

You can use (char) System.in.read();.

This was perfect for me. You will get the return code, stdout and stderr in a tuple.

from subprocess import Popen, PIPE

def console(cmd):
    p = Popen(cmd, shell=True, stdout=PIPE)
    out, err = p.communicate()
    return (p.returncode, out, err)

For Example:

result = console('ls -l')
print 'returncode: %s' % result[0]
print 'output: %s' % result[1]
print 'error: %s' % result[2]

This function will be used get the data from url in form of HttpResponse object.

public HttpResponse getRespose(String url, String your_auth_code){
HttpClient client = new DefaultHttpClient();
HttpPost postForGetMethod = new HttpPost(url);
postForGetMethod.addHeader("Content-type", "Application/JSON");
postForGetMethod.addHeader("Authorization", your_auth_code);
return client.execute(postForGetMethod);
}

Above function is called here and we receive a String form of the json using the Apache library Class.And in following statements we try to make simple pojo out of the json we received.

String jsonString     =     
EntityUtils.toString(getResponse("http://echo.jsontest.com/title/ipsum/content/    blah","Your_auth_if_you_need_one").getEntity(), "UTF-8");
final GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.registerTypeAdapter(JsonJavaModel .class, new    CustomJsonDeserialiser());
final Gson gson = gsonBuilder.create();
JsonElement json = new JsonParser().parse(jsonString);
JsonJavaModel pojoModel = gson.fromJson(
                    jsonElementForJavaObject, JsonJavaModel.class);

This is a simple java model class for incomming json. public class JsonJavaModel{ String content; String title; } This is a custom deserialiser:

public class CustomJsonDeserialiserimplements JsonDeserializer<JsonJavaModel>         {

@Override
public JsonJavaModel deserialize(JsonElement json, Type type,
                                 JsonDeserializationContext arg2) throws    JsonParseException {
    final JsonJavaModel jsonJavaModel= new JsonJavaModel();
    JsonObject object = json.getAsJsonObject();

    try {
     jsonJavaModel.content = object.get("Content").getAsString()
     jsonJavaModel.title = object.get("Title").getAsString()

    } catch (Exception e) {

        e.printStackTrace();
    }
    return jsonJavaModel;
}

Include Gson library and org.apache.http.util.EntityUtils;

I made a tool using Python with some bash to trigger a Jenkins build. Basically you have to collect these two values from post-commit when a commit hits the SVN server:

REPOS="$1"
REV="$2"

Then you use "svnlook dirs-changed $1 -r $2" to get the path which is has just committed. Then from that you can check which repository you want to build. Imagine you have hundred of thousand of projects. You can't check the whole repository, right?

You can check out my script from GitHub.

If you only want to verify that issuer of UserCert.pem is actually Intermediate.pem do the following (example uses: OpenSSL 1.1.1):

openssl verify -no-CAfile -no-CApath -partial_chain -trusted Intermediate.pem UserCert.pem

and you will get:

UserCert.pem: OK

or

UserCert.pem: verification failed

Up through C++03, your first example was valid, but used a deprecated implicit conversion--a string literal should be treated as being of type char const *, since you can't modify its contents (without causing undefined behavior).

As of C++11, the implicit conversion that had been deprecated was officially removed, so code that depends on it (like your first example) should no longer compile.

You've noted one way to allow the code to compile: although the implicit conversion has been removed, an explicit conversion still works, so you can add a cast. I would not, however, consider this "fixing" the code.

Truly fixing the code requires changing the type of the pointer to the correct type:

char const *p = "abc"; // valid and safe in either C or C++.

As to why it was allowed in C++ (and still is in C): simply because there's a lot of existing code that depends on that implicit conversion, and breaking that code (at least without some official warning) apparently seemed to the standard committees like a bad idea.

While reading the TCP UDP debate I noticed a logical flaw. A TCP packet loss causing a one minute delay that's converted into a one minute buffer cant be correlated to UDP dropping a full minute while experiencing the same loss. A more fair comparison is as follows.

TCP experiences a packet loss. The video is stopped while TCP resend's packets in an attempt to stream mathematically perfect packets. Video is delayed for one minute and picks up where it left off after missing packet makes its destination. We all wait but we know we wont miss a single pixel.

UDP experiences a packet loss. For a second during the video stream a corner of the screen gets a little blurry. No one notices and the show goes on without looking for the lost packets.

Anything that streams gains the most benefits from UDP. The packet loss causing a one minute delay to TCP would not cause a one minute delay to UDP. Considering that most systems use multiple resolution streams making things go blocky when starving for packets, makes even more sense to use UDP.

UDP FTW when streaming.

From http://www.sqlite.org/lang_createtable.html:

CREATE TABLE IF NOT EXISTS some_table (id INTEGER PRIMARY KEY AUTOINCREMENT, ...);

$.getJSON(url,function(json){
if ( json.length == 0 ) 
{
console.log("NO !")
}
});

another solution, cut the string in 2 and put a string in between.

var str = jQuery('#selector').text();

var strlength = str.length;

strf = str.substr(0 , strlength - 5);
strb = str.substr(strlength - 5 , 5);

jQuery('#selector').html(strf + 'inserted' + strb);

Create a zip or tar file and upload in phpmyadmin thats it..!

The problem is described (among other) in this article.

#box is relatively positioned, which makes it part of the "flow" of the page. Your other divs are absolutely positioned, so they are removed from the page's "flow".

Page flow means that the positioning of an element effects other elements in the flow.

In other words, as #box now sees the dom, .a and .b are no longer "inside" #box.

To fix this, you would want to make everything relative, or everything absolute.

One way would be:

.a {
   position:relative;
   margin-top:10px;
   margin-left:10px;
   background-color:red;
   width:210px;
   padding: 5px;
}

Follow these steps:

1. Generate an APNs Auth Key
Open the APNs Auth Key page in your Developer Center and click the + button to create a new APNs Auth Key.

In the next page, select Apple Push Notification Authentication Key (Sandbox & Production) and click Continue at the bottom of the page.

Apple will then generate a .p8 key file containing your APNs Auth Key.

Download the .p8 key file to your computer and save it for later. Also, be sure to write down the Key ID somewhere, as you'll need it later when connecting to APNs.

2. Send Push Notifications

Ref: APNS (Configure push notifications)

Important: Save a back up of your key in a secure place. It will not be presented again and cannot be retrieved later.

I had a case very similar where I was posting in an each loop and then setting the html markup in some fields from numbers received from the ajax. I then needed to do a sum of the (now-updated) values of these fields and place in a total field.

Thus the problem was that I was trying to do a sum on all of the numbers but no data had arrived back yet from the async ajax calls. I needed to complete this functionality in a few functions to be able to reuse the code. My outer function awaits the data before I then go and do some stuff with the fully updated DOM.

    // 1st
    function Outer() {
        var deferreds = GetAllData();

        $.when.apply($, deferreds).done(function () {
            // now you can do whatever you want with the updated page
        });
    }

    // 2nd
    function GetAllData() {
        var deferreds = [];
        $('.calculatedField').each(function (data) {
            deferreds.push(GetIndividualData($(this)));
        });
        return deferreds;
    }

    // 3rd
    function GetIndividualData(item) {
        var def = new $.Deferred();
        $.post('@Url.Action("GetData")', function (data) {
            item.html(data.valueFromAjax);
            def.resolve(data);
        });
        return def;
    }

If you found “HAX is not working and emulator runs in emulation mode” problem while running android SDK. This mean your computer CPU must be intel core and must support “Hardware Accelerated Execution Manager”. It means that you have configured the emulator in a way which is not supported by your operating system.

See this link solving the problem http://www.javaexperience.com/hax-is-not-working-and-emulator-runs-in-emulation-mode/#ixzz2p3inMj34

Update : -

If your CPU isn't intel, then you have to edit your AVD and choose "CPU/ABI" as "ARM". For more details, please visit the link above.

Parallelism: Having multiple threads do similar task which are independent of each other in terms of data and resource that they require to do so. Eg: Google crawler can spawn thousands of threads and each thread can do it's task independently.

Concurrency: Concurrency comes into picture when you have shared data, shared resource among the threads. In a transactional system this means you have to synchronize the critical section of the code using some techniques like Locks, semaphores, etc.

I was asking myself the same question but the problem with the current answers is that they don't safe check the processes to be killed so... it could lead to terrible mistakes :)... especially if several processes matches the pattern.

As a disclaimer, I'm not a sh pro and there is certainly room for improvement.

So I wrote a little sh script :

#!/bin/sh

killables=$(ps aux | grep $1 | grep -v mykill | grep -v grep)
if [ ! "${killables}" = "" ]
then
  echo "You are going to kill some process:"
  echo "${killables}"
else
  echo "No process with the pattern $1 found."
  return
fi
echo -n "Is it ok?(Y/N)"
read input
if [ "$input" = "Y" ]
then
  for pid in $(echo "${killables}" | awk '{print $2}')
  do
    echo killing $pid "..."
    kill $pid 
    echo $pid killed
  done
fi

For me doesnt put jars to lib directory and set to Build path enought.

The right thing was add it to Deployment Assembly.

Original asnwer

I found that when my fragment was defined in the navigation graph with a <fragment> tag (for a full screen dialogfragment), the dialogfragment would not dismiss with the dismiss() command. Instead, I had to pop the back stack:

findNavController(getActivity(), R.id.nav_host_fragment).popBackStack();

However, if the same dialogfragment was defined in the navigation graph with a <dialog> tag, dismiss() works fine.

Correct on all fronts. Outside of a character class (that's what the "square brackets" are called) the hyphen has no special meaning, and within a character class, you can place a hyphen as the first or last character in the range (e.g. [-a-z] or [0-9-]), OR escape it (e.g. [a-z\-0-9]) in order to add "hyphen" to your class.

It's more common to find a hyphen placed first or last within a character class, but by no means will you be lynched by hordes of furious neckbeards for choosing to escape it instead.

(Actually... my experience has been that a lot of regex is employed by folks who don't fully grok the syntax. In these cases, you'll typically see everything escaped (e.g. [a-z\%\$\#\@\!\-\_]) simply because the engineer doesn't know what's "special" and what's not... so they "play it safe" and obfuscate the expression with loads of excessive backslashes. You'll be doing yourself, your contemporaries, and your posterity a huge favor by taking the time to really understand regex syntax before using it.)

Great question!

Query syntax:

var count = (from o in context.MyContainer
             where o.ID == '1'
             from t in o.MyTable
             select t).Count();

Method syntax:

var count = context.MyContainer
            .Where(o => o.ID == '1')
            .SelectMany(o => o.MyTable)
            .Count()

Both generate the same SQL query.

The cool thing about the new Google Recaptcha is that the validation is now completely encapsulated in the widget. That means, that the widget will take care of asking questions, validating responses all the way till it determines that a user is actually a human, only then you get a g-recaptcha-response value.

But that does not keep your site safe from HTTP client request forgery.

Anyone with HTTP POST knowledge could put random data inside of the g-recaptcha-response form field, and foll your site to make it think that this field was provided by the google widget. So you have to validate this token.

In human speech it would be like,

• Your Server: Hey Google, there's a dude that tells me that he's not a robot. He says that you already verified that he's a human, and he told me to give you this token as a proof of that.
• Google: Hmm... let me check this token... yes I remember this dude I gave him this token... yeah he's made of flesh and bone let him through.
• Your Server: Hey Google, there's another dude that tells me that he's a human. He also gave me a token.
• Google: Hmm... it's the same token you gave me last time... I'm pretty sure this guy is trying to fool you. Tell him to get off your site.

Validating the response is really easy. Just make a GET Request to

https://www.google.com/recaptcha/api/siteverify?secret=your_secret&response=response_string&remoteip=user_ip_address

And replace the response_string with the value that you earlier got by the g-recaptcha-response field.

You will get a JSON Response with a success field.

More information here: https://developers.google.com/recaptcha/docs/verify

Edit: It's actually a POST, as per documentation here.

One possiblity is to use a NULL pointer as a flag value:

const char *list[] = {"dog", "cat", NULL};
for (char **iList = list; *iList != NULL; ++iList)
{
    cout << *iList;
}

def my_func(mandatory_arg, optional_arg=100):
    print(mandatory_arg, optional_arg)

http://docs.python.org/2/tutorial/controlflow.html#default-argument-values

I find this more readable than using **kwargs.

To determine if an argument was passed at all, I use a custom utility object as the default value:

MISSING = object()

def func(arg=MISSING):
    if arg is MISSING:
        ...

I combined a few answers given by others in this question to come up with another alternative solution.

Goal: To always bundle the files, to disable the JS and CSS minification in the event that <compilation debug="true" ... /> and to always apply a custom transformation to the CSS bundle.

My solution:

1) In web.config: <compilation debug="true" ... />

2) In the Global.asax Application_Start() method:

 protected void Application_Start() {
     ...
     BundleTable.EnableOptimizations = true; // Force bundling to occur

     // If the compilation node in web.config indicates debugging mode is enabled
     // then clear all transforms. I.e. disable Js and CSS minification.
     if (HttpContext.Current.IsDebuggingEnabled) {
         BundleTable.Bundles.ToList().ForEach(b => b.Transforms.Clear());
     }

      // Add a custom CSS bundle transformer. In my case the transformer replaces a
      // token in the CSS file with an AppConfig value representing the website URL
      // in the current environment. E.g. www.mydevwebsite in Dev and
      // www.myprodwebsite.com in Production.
      BundleTable.Bundles.ToList()
          .FindAll(x => x.GetType() == typeof(StyleBundle))
          .ForEach(b => b.Transforms.Add(new MyStyleBundleTransformer()));
     ...
}

If you already have python3 installed as well virtualenvwrapper the only thing you would need to do to use python3 with the virtual environment is creating an environment using:

which python3 #Output: /usr/bin/python3
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment

Or, (at least on OSX using brew):

mkvirtualenv --python=`which python3` nameOfEnvironment

Start using the environment and you'll see that as soon as you type python you'll start using python3

I needed the default “Please Select” to be unselectable. I also needed to be able to conditionally set a default selected option.

I achieved this the following simplistic way: JS code: // Flip these 2 to test selected default or no default with default “Please Select” text //$scope.defaultOption = 0; $scope.defaultOption = { key: '3', value: 'Option 3' };

$scope.options = [
   { key: '1', value: 'Option 1' },
   { key: '2', value: 'Option 2' },
   { key: '3', value: 'Option 3' },
   { key: '4', value: 'Option 4' }
];

getOptions();

function getOptions(){
    if ($scope.defaultOption != 0)
    { $scope.options.selectedOption = $scope.defaultOption; }
}

HTML:

<select name="OptionSelect" id="OptionSelect" ng-model="options.selectedOption" ng-options="item.value for item in options track by item.key">
<option value="" disabled selected style="display: none;"> -- Please Select -- </option>
</select>
<h1>You selected: {{options.selectedOption.key}}</h1>         

I hope this helps someone else that has similar requirements.

The "Please Select" was accomplished through Joffrey Outtier's answer here.

In most cases, it really doesn't matter that much. Just pick a good size such as 4K or 16K and stick with it. If you're positive that this is the bottleneck in your application, then you should start profiling to find the optimal buffer size. If you pick a size that's too small, you'll waste time doing extra I/O operations and extra function calls. If you pick a size that's too big, you'll start seeing a lot of cache misses which will really slow you down. Don't use a buffer bigger than your L2 cache size.

More simple: SELECT max(id) FROM client

And for all SQL Server versions

SELECT CAST(0.973684210526315789 * 100 AS DECIMAL(18, 2))

To find all of the lengths of the values in a dictionary you can do this:

lengths = [len(v) for v in d.values()]

This work at least in the Debian Jessie image hosted by Google:

The way to enable to switch from you regular to the root user (AKA “super user”) after authentificating with your Google Computer Engine (GCE) User in the local environment (your Linux server in GCE) is pretty straight forward, in fact it just involves just one command to enable it and another every time to use it:

$ sudo passwd
Enter the new UNIX password: <your new root password>
Retype the new UNIX password: <your new root password>
passwd: password updated successfully

After executing the previous command and once logged with your GCE User you will be able to switch to root anytime by just entering the following command:

$ su
Password: <your newly created root password>
root@intance:/#

As we say in economics “caveat emptor” or buyer be aware: Using the root user is far from a best practice in system’s administration. Using it can be the cause a lot of trouble, from wiping everything in your drives and boot disks without a hiccup to many other nasty stuff that would be laborious to backtrack, troubleshoot and rebuilt. On the other hand, I have never met a SysAdmin that doesn’t think he knows better and root more than he should.

REMEMBER: We humans are programmed in such a way that given enough time at one at some point or another are going to press enter without taking into account that we have escalated to root and I can assure you that it will great source of pain, regret and extra work. PLEASE USE ROOT PRIVILEGES SPARSELY AND WITH EXTREME CARE.

Having said all the boring stuff, Have fun, live on the edge, life is short, you only get to live it once, the more you break the more you learn.

What about Regex.Escape(String) ?

Regex.Escape escapes a minimal set of characters (\, *, +, ?, |, {, [, (,), ^, $,., #, and white space) by replacing them with their escape codes.

So I have been struggling with this issue for two hours and I have come up with a working solution for all API versions, where half stars ratings are also shown.

private void setRatingStarColor(Drawable drawable, @ColorInt int color)
{
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
    {
        DrawableCompat.setTint(drawable, color);
    }
    else
    {
        drawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);
    }
}

You call the method with this order of drawables:

    LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
    // Filled stars
    setRatingStarColor(stars.getDrawable(2), ContextCompat.getColor(getContext(), R.color.foreground));
    // Half filled stars
    setRatingStarColor(stars.getDrawable(1), ContextCompat.getColor(getContext(), R.color.background));
    // Empty stars
    setRatingStarColor(stars.getDrawable(0), ContextCompat.getColor(getContext(), R.color.background));

NOTE: Also you must specify attributes "max" and "numStars" in XML, otherwise half stars aren't shown.

I was having this same issue for both Windows 8 and Windows Server 2012 configurations. I had installed the latest version of JDK Java 7 and had set my **JAVA_HOME**system env variable to the jre folder: *C:\Program Files (x86)\Java\jre7* I also added the bin folder to my **Path** system env variable: *%JAVA_HOME%\bin*

But I was still having problems with double clicking the executable jar files. I found another system env variable OPENDS_JAVA_ARGS that can be used to set the optional properties for javaw.exe. So I added this variable and set it to: -jar

Now I am able to run the executable jar files when double clicking them.

If you are having a code structure of something like:

SELECT 151
RETURN -151

Then use:

SELECT 151
ROLLBACK
RETURN -151

Try replaceAll() method of the String class.

BTW here is the method, return type and parameters.

public String replaceAll(String regex,
                         String replacement)

Example:

String str = "Hello +-^ my + - friends ^ ^^-- ^^^ +!";
str = str.replaceAll("[-+^]*", "");

It should remove all the {'^', '+', '-'} chars that you wanted to remove!

To add MP3 reading support to Java Sound, add the mp3plugin.jar of the JMF to the run-time class path of the application.

Note that the Clip class has memory limitations that make it unsuitable for more than a few seconds of high quality sound.

I had this problem while trying to brew upgrade on MacOS X 10.7.5.

Unfortunately mysql was also upgraded to 5.6.10 from 5.5.14. Tried the new, did not work.

I decided to go back to my old setup and did a

brew switch mysql 5.5.14

This did not solve the problem. Elsewhere I read and did this, voila! All was back :)

cd /usr/local/var/mysql
mv ib_logfile0 ib_logfile0.bak
mv ib_logfile1 ib_logfile1.bak

The environment variables of a process exist at runtime, and are not stored in some file or so. They are stored in the process's own memory (that's where they are found to pass on to children). But there is a virtual file in

/proc/pid/environ

This file shows all the environment variables that were passed when calling the process (unless the process overwrote that part of its memory — most programs don't). The kernel makes them visible through that virtual file. One can list them. For example to view the variables of process 3940, one can do

cat /proc/3940/environ | tr '\0' '\n'

Each variable is delimited by a binary zero from the next one. tr replaces the zero into a newline.

Another way of doing is: In Controller, create a variable to hold the current date as shown below:

var eventsApp = angular.module("eventsApp", []);
eventsApp.controller("EventController", function EventController($scope) 
{

 $scope.myDate = Date.now();

});

In HTML view,

<!DOCTYPE html>
<html ng-app="eventsApp">
<head>
    <meta charset="utf-8" />
   <title></title>
   <script src="lib/angular/angular.js"></script>
</head>
<body>
<div ng-controller="EventController">
<span>{{myDate | date : 'yyyy-MM-dd'}}</span>
</div>
</body>
</html>

I think you can load it in a Word document object by using .NET office programmability support and Visual Studio tools for office.

And then use the document instance to re-save as an HTML document.

I am not sure how but I believe it is possible entirely in .NET without any 3rd party library.

If anyone wants to add an URL on a single marker which not require for loops, here is how it goes:

if ($('#googleMap').length) {
    var initialize = function() {
        var mapOptions = {
            zoom: 15,
            scrollwheel: false,
            center: new google.maps.LatLng(45.725788, -73.5120818),
            styles: [{
                stylers: [{
                    saturation: -100
                }]
            }]
        };
        var map = new google.maps.Map(document.getElementById("googleMap"), mapOptions);
        var marker = new google.maps.Marker({
            position: map.getCenter(),
            animation: google.maps.Animation.BOUNCE,
            icon: 'example-marker.png',
            map: map,
            url: 'https://example.com'
        });

        //Add an url to the marker
    google.maps.event.addListener(marker, 'click', function() {
        window.location.href = this.url;
    });
    }
    // Add the map initialize function to the window load function
    google.maps.event.addDomListener(window, "load", initialize);
}

Just an update of James' answer.

Isn't this the normal way to free the memory associated with an object?

Yes. It is the normal way to free memory. But new/delete operator always leads to memory leak problem.

Since c++17 already removed auto_ptr auto_ptr. I suggest shared_ptr or unique_ptr to handle the memory problems.

void test()
{
    std::shared_ptr<Object1> obj1(new Object1);

} // The object is automatically deleted when the scope ends or reference counting reduces to 0.

• The reason for removing auto_ptr is that auto_ptr is not stable in case of coping semantics
• If you are sure about no coping happening during the scope, a unique_ptr is suggested.
• If there is a circular reference between the pointers, I suggest having a look at weak_ptr.

I fixed this by removing one of the unneeded NuGet packaged referenced in the dll files causing this conflict.

So in this case I had both ZXing.Net and ZXing.Net.Mobile installed. Since I was creating a mobile app in Xamarin Forms, removing the ZXing.Net NuGet package resolved this.

Be sure to check and make sure you don't have redundant NuGet packages for different frameworks, i.e. ASP.Net versus Xamarin.

I have to agree with Vladimir. I too looked into using UNION in HQL and couldn't find a way around it. The odd thing was that I could find (in the Hibernate FAQ) that UNION is unsupported, bug reports pertaining to UNION marked 'fixed', newsgroups of people saying that the statements would be truncated at UNION, and other newsgroups of people reporting it works fine... After a day of mucking with it, I ended up porting my HQL back to plain SQL, but doing it in a View in the database would be a good option. In my case, parts of the query were dynamically generated, so I had to build the SQL in the code instead.

Set WorkingDirectory or specify the full path of the python script in the Argument

ProcessStartInfo start = new ProcessStartInfo();
start.FileName = "C:\\Python27\\python.exe";
//start.WorkingDirectory = @"D:\script";
start.Arguments = string.Format("D:\\script\\test.py -a {0} -b {1} ", "some param", "some other param");
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
using (Process process = Process.Start(start))
{
    using (StreamReader reader = process.StandardOutput)
    {
        string result = reader.ReadToEnd();
        Console.Write(result);
    }
}

In my experience, rules engines work best when the following are true:

1. Well-defined doctrine for your problem domain
2. High quality (preferably automated) data to help drive most of your inputs
3. Access to subject matter experts
4. Software developers with experience creating expert systems

If any of these four traits are missing, you still might find a rules engine works for you, but every time I've tried it with even 1 missing, I've run into trouble.

When we are going to migrate JQuery from 1.x to 2x or 3.x in our old existing application , then we will use .done,.fail instead of success,error as JQuery up gradation is going to be deprecated these methods.For example when we make a call to server web methods then server returns promise objects to the calling methods(Ajax methods) and this promise objects contains .done,.fail..etc methods.Hence we will the same for success and failure response. Below is the example(it is for POST request same way we can construct for request type like GET...)

 $.ajax({
            type: "POST",
            url: url,
            data: '{"name" :"sheo"}',
            contentType: "application/json; charset=utf-8",
            async: false,
            cache: false
            }).done(function (Response) {
                  //do something when get response            })
           .fail(function (Response) {
                    //do something when any error occurs.
                });

This is an implementation of aforementioned StanLe's anwer, also fixing the case where his answer would produce no curve when using densities.

This replaces the existing but hidden hist.default() function, to only add the normalcurve parameter (which defaults to TRUE).

The first three lines are to support roxygen2 for package building.

#' @noRd
#' @exportMethod hist.default

                         include.lowest = TRUE,
                         normalcurve = TRUE,
                         right = TRUE,
                         density = NULL,
                         angle = 45,

For dates it's bit different. For reference:

#' @export
hist.Date <- function(x,
                      breaks = "months",

    )
  )

  if (normalcurve == TRUE & plot == TRUE) {

    xfit <- seq(min(x), max(x), length = 40)
    yfit <- dnorm(xfit, mean = mean(x), sd = sd(x))
    if (isTRUE(freq) | (is.null(freq) & is.null(density))) {
      yfit <- as.double(yfit) * diff(h$mids[1:2]) * length(x)
    }
    lines(xfit, yfit, col = "black", lwd = 2)
  }

  if (plot == TRUE) {

  }
}

Below is a good solution in Java though!

NumberFormat fmt = NumberFormat.getCurrencyInstance();
System.out.println(fmt.format(n));

or for a more robust way you may want to get the locale of a particular place, then use as below:

int n=9999999;
Locale locale = new Locale("en", "US");
NumberFormat fmt = NumberFormat.getCurrencyInstance(locale);
System.out.println(fmt.format(n));

US Locale OUTPUT: $9,999,999.00

German Locale output

Locale locale = new Locale("de", "DE");

OUTPUT: 9.999.999,00 €

Indian Locale output

Locale locale = new Locale("de", "DE");

OUTPUT: Rs.9,999,999.00

Estonian Locale output

Locale locale = new Locale("et", "EE");

OUTPUT: 9 999 999 €

As you can see in different outputs you don't have to worry about the separator being a comma or dot or even space you can get the number formatted according to the i18n standards

If you don't want to use anonymous types b/c let's say you're passing the object to another method, you can use the LoadWith load option to load associated data. It requires that your tables are associated either through foreign keys or in your Linq-to-SQL dbml model.

db.DeferredLoadingEnabled = false;
DataLoadOptions dlo = new DataLoadOptions();
dlo.LoadWith<ObjectPermissions>(op => op.Pages)
db.LoadOptions = dlo;

var pageObject = from op in db.ObjectPermissions
         select op;

// no join needed

Then you can call

pageObject.Pages.PageID

Depending on what your data looks like, you'd probably want to do this the other way around,

DataLoadOptions dlo = new DataLoadOptions();
dlo.LoadWith<Pages>(p => p.ObjectPermissions)
db.LoadOptions = dlo;

var pageObject = from p in db.Pages
                 select p;

// no join needed

var objectPermissionName = pageObject.ObjectPermissions.ObjectPermissionName;

Adding to Dmitri Chebotarev's answer, as for Laravel 5+.

After requiring the doctrine/dbal package:

composer require doctrine/dbal

You can then make a migration with nullable columns, like so:

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        // change() tells the Schema builder that we are altering a table
        $table->integer('user_id')->unsigned()->nullable()->change();
    });
}

To revert the operation, do:

public function down()
{
    /* turn off foreign key checks for a moment */
    DB::statement('SET FOREIGN_KEY_CHECKS = 0');
    /* set null values to 0 first */
    DB::statement('UPDATE `users` SET `user_id` = 0 WHERE `user_id` IS NULL;');
    /* alter table */
    DB::statement('ALTER TABLE `users` MODIFY `user_id` INTEGER UNSIGNED NOT NULL;');
    /* finally turn foreign key checks back on */
    DB::statement('SET FOREIGN_KEY_CHECKS = 1');
}

No solution mentioned above was solved my problem. My problem was different.

First check is your port is disabled in firewall. Go to Control Panel -> Windows Firewall -> Advance Settings -> Inbound Rules and see any port is blocked.

A sample image is below:

If so then you can unblock the port by following steps:

Step 1:

Here you can see that the port is blocked.

Step 2: Allow the connection -> Apply -> Ok.

That's solved my blocked problem. Happy coding :) :)

edit: shortid has been deprecated. The maintainers recommend to use nanoid instead.

Another approach is using the shortid package from npm.

It is very easy to use:

var shortid = require('shortid');
console.log(shortid.generate()); // e.g. S1cudXAF

and has some compelling features:

ShortId creates amazingly short non-sequential url-friendly unique ids. Perfect for url shorteners, MongoDB and Redis ids, and any other id users might see.

• By default 7-14 url-friendly characters: A-Z, a-z, 0-9, _-
• Non-sequential so they are not predictable.
• Can generate any number of ids without duplicates, even millions per day.
• Apps can be restarted any number of times without any chance of repeating an id.

I always go back to this article SQL Server 2005 XQuery and XML-DML - Part 1 to know how to use the XML features in SQL Server 2005.

For basic XPath know-how, I'd recommend the W3Schools tutorial.

-Xmx1024m -XX:MaxPermSize=512m -Xms512m

Add this parameter as argument in your server params

If you want to hide gridlines but want to show yAxes, you can set:

yAxes: [{...
         gridLines: {
                        drawBorder: true,
                        display: false
                    }
       }]

As of July 2018 and the release of RxJS 6, the new way to get an Observable from a value is to import the of operator like so:

import { of } from 'rxjs';

and then create the observable from the value, like so:

of(someValue);

Note, that you used to have to do Observable.of(someValue) like in the currently accepted answer. There is a good article on the other RxJS 6 changes here.

We recently encountered this error, root cause turned out to be an expired SSL cert on the IIS server. The Load Balancer (infront of our web tier) found the SSL expired, and instead of handling the HTTP traffic over to one of the IIS servers, started showing this error. So basically IIS unable to server requests, for a totally different reason :)

Use position: fixed instead of position: absolute.

See here.

You can use the datetime module for working with dates and times in Python. The strftime method allows you to produce string representation of dates and times with a format you specify.

>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'

Found another way:

import json
print json.dumps(d, sort_keys = True)

upd:
1. this also sorts nested objects (thanks @DanielF).
2. python dictionaries are unordered therefore this is sutable for print or assign to str only.

Here's a jquery plugin to do the same: http://s.technabled.com/jquery-foggle

This is the answer, hope it helps someone :)

First there are two variations on how the xml can be written:

1

<row>
    <IdInvernadero>8</IdInvernadero>
    <IdProducto>3</IdProducto>
    <IdCaracteristica1>8</IdCaracteristica1>
    <IdCaracteristica2>8</IdCaracteristica2>
    <Cantidad>25</Cantidad>
    <Folio>4568457</Folio>
</row>
<row>
    <IdInvernadero>3</IdInvernadero>
    <IdProducto>3</IdProducto>
    <IdCaracteristica1>1</IdCaracteristica1>
    <IdCaracteristica2>2</IdCaracteristica2>
    <Cantidad>72</Cantidad>
    <Folio>4568457</Folio>
</row>

Answer:

SELECT  
       Tbl.Col.value('IdInvernadero[1]', 'smallint'),  
       Tbl.Col.value('IdProducto[1]', 'smallint'),  
       Tbl.Col.value('IdCaracteristica1[1]', 'smallint'),
       Tbl.Col.value('IdCaracteristica2[1]', 'smallint'),
       Tbl.Col.value('Cantidad[1]', 'int'),
       Tbl.Col.value('Folio[1]', 'varchar(7)')
FROM   @xml.nodes('//row') Tbl(Col)  

2.

<row IdInvernadero="8" IdProducto="3" IdCaracteristica1="8" IdCaracteristica2="8" Cantidad ="25" Folio="4568457" />                         
<row IdInvernadero="3" IdProducto="3" IdCaracteristica1="1" IdCaracteristica2="2" Cantidad ="72" Folio="4568457" />

Answer:

SELECT  
       Tbl.Col.value('@IdInvernadero', 'smallint'),  
       Tbl.Col.value('@IdProducto', 'smallint'),  
       Tbl.Col.value('@IdCaracteristica1', 'smallint'),
       Tbl.Col.value('@IdCaracteristica2', 'smallint'),
       Tbl.Col.value('@Cantidad', 'int'),
       Tbl.Col.value('@Folio', 'varchar(7)')

FROM   @xml.nodes('//row') Tbl(Col)

The easiest way is to CAST the value as FLOAT and then to a string data type.

CAST(CAST(123.456000 AS FLOAT) AS VARCHAR(100))

One reason to use SELECT INTO is that it allows you to use IDENTITY:

SELECT IDENTITY(INT,1,1) AS Id, name
INTO #MyTable 
FROM (SELECT name FROM AnotherTable) AS t

This would not work with a table variable, which is too bad...

With recent browser support of "Clear-Site-Data" headers, you can clear different types of data: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Clear-Site-Data

header('Clear-Site-Data: "cache", "cookies", "storage", "executionContexts"');

PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(foo);

foreach (PropertyDescriptor property in properties)
{
    if (property.Name == "Name")
    {
        Console.WriteLine(property.DisplayName); // Something To Name
    }
}

where foo is an instance of Class1

Simply do it this way...

Double d = 13.5578;
int i = d.intValue();
System.out.println(i);

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

If you are working with API, then you can use it as:

import moment from 'moment'
...

        this.state = {
            List: []
        };
    }


    componentDidMount() {
        this.getData();
    }
    // Show List
    getData() {
        fetch('url')
            .then((response) => {
                response.json()
                    .then((result) => {
                        this.setState({ List: result })
                    })
            })
    }
this.state.List = 
this.state.List.map(row => ({...row, dob: moment(row.dob).format("YYYY/MM/DD")}))

...

On Windows you can also set the environment property OPENSSL_CONF. For example from the commandline you can type:

set OPENSSL_CONF=c:/libs/openssl-0.9.8k/openssl.cnf

to validate it you can type:

echo %OPENSSL_CONF%

You can also set it as part of the computer's environmental variables so all users and services have it available by default. See, for example, Environment variables in Windows NT and How To Manage Environment Variables in Windows XP.

Now you can run openssl commands without having to pass the config location parameter.

I get the same error in Cygwin. I had to install the openssh package in Cygwin Setup.

(The strange thing was that all ssh-* commands were valid, (bash could execute as program) but the openssh package wasn't installed.)

keytool is located in JDK bin directory ($JAVA_HOME/bin). JAVA_HOME is your JDK installation directory. To use that command line you should also include $JAVA_HOME/bin to your PATH environment variable.

Their is no agreement on the rest api response formats of big software giants - Google, Facebook, Twitter, Amazon and others, though many links have been provided in the answers above, where some people have tried to standardize the response format.

As needs of the API's can differ it is very difficult to get everyone on board and agree to some format. If you have millions of users using your API, why would you change your response format?

Following is my take on the response format inspired by Google, Twitter, Amazon and some posts on internet:

if you want infos from the actual running batchfile, try this :

@echo off
set myNameFull=%0
echo myNameFull     %myNameFull%
set myNameShort=%~n0
echo myNameShort    %myNameShort%
set myNameLong=%~nx0
echo myNameLong     %myNameLong%
set myPath=%~dp0
echo myPath         %myPath%
set myLogfileWpath=%myPath%%myNameShort%.log
echo myLogfileWpath %myLogfileWpath%

more samples? C:> HELP CALL

%0 = parameter 0 = batchfile %1 = parameter 1 - 1st par. passed to batchfile... so you can try that stuff (e.g. "~dp") between 1st (e.g. "%") and last (e.g. "1") also for parameters

I got it working with a call to something as simple as

function fb_login() {
  FB.login( function() {}, { scope: 'email,public_profile' } );
}

I don't know if facebook will ever be able to block this circumvention, but for now I can use whatever HTML or image I want to call fb_login and it works fine.

Try something like this when you are applying focus that way if the element is hidden, it won't throw an error:

$("#elementid").filter(':visible').focus();

It may make more sense to make the element visible, though that will require code specific to your layout.
