In the latter case, if obj is null you won't get a NullPointerException but a false.

The following works for me:

function decodeHtml(html) {
    let areaElement = document.createElement("textarea");
    areaElement.innerHTML = html;

    return areaElement.value;
}

You can't single out individual columns in a cell in that manner. In my opinion, your best option is to add a style='padding-left:10px' on the second column and apply the styles on an internal div or element. This way you can achieve the illusion of a greater space.

See http://poi.apache.org/spreadsheet/quick-guide.html#CustomColors.

Custom colors

HSSF:

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet();
HSSFRow row = sheet.createRow((short) 0);
HSSFCell cell = row.createCell((short) 0);
cell.setCellValue("Default Palette");

//apply some colors from the standard palette,
// as in the previous examples.
//we'll use red text on a lime background

HSSFCellStyle style = wb.createCellStyle();
style.setFillForegroundColor(HSSFColor.LIME.index);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

HSSFFont font = wb.createFont();
font.setColor(HSSFColor.RED.index);
style.setFont(font);

cell.setCellStyle(style);

//save with the default palette
FileOutputStream out = new FileOutputStream("default_palette.xls");
wb.write(out);
out.close();

//now, let's replace RED and LIME in the palette
// with a more attractive combination
// (lovingly borrowed from freebsd.org)

cell.setCellValue("Modified Palette");

//creating a custom palette for the workbook
HSSFPalette palette = wb.getCustomPalette();

//replacing the standard red with freebsd.org red
palette.setColorAtIndex(HSSFColor.RED.index,
        (byte) 153,  //RGB red (0-255)
        (byte) 0,    //RGB green
        (byte) 0     //RGB blue
);
//replacing lime with freebsd.org gold
palette.setColorAtIndex(HSSFColor.LIME.index, (byte) 255, (byte) 204, (byte) 102);

//save with the modified palette
// note that wherever we have previously used RED or LIME, the
// new colors magically appear
out = new FileOutputStream("modified_palette.xls");
wb.write(out);
out.close();

XSSF:

XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet();
XSSFRow row = sheet.createRow(0);
XSSFCell cell = row.createCell( 0);
cell.setCellValue("custom XSSF colors");

XSSFCellStyle style1 = wb.createCellStyle();
style1.setFillForegroundColor(new XSSFColor(new java.awt.Color(128, 0, 128)));
style1.setFillPattern(CellStyle.SOLID_FOREGROUND);

In general you can use Object class for any type, but you have do type casting later!

eg:-

Object object = 12;
    Object object1 = "Aditya";
    Object object2 = 12.12;

    System.out.println(Integer.parseInt(object.toString()) + 2);

    System.out.println(object1.toString() + " Kumar");
    System.out.println(Double.parseDouble(object2.toString()) + 2.12);

XMLHttpRequest is a built-in object in web browsers.

It is not distributed with Node; you have to install it separately,

1. Install it with npm,

   npm install xmlhttprequest
   

2. Now you can require it in your code.

   var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
   var xhr = new XMLHttpRequest();
   

That said, the http module is the built-in tool for making HTTP requests from Node.

Axios is a library for making HTTP requests which is available for Node and browsers that is very popular these days.

There are multiple methods to do that:

Method 1:

alert($('.checkbox_class_here:checked').size());

Method 2:

alert($('input[name=checkbox_name]').attr('checked'));

Method 3:

alert($(":checkbox:checked").length);

Okay you got the syntax wrong here, correct way to do this is:

var arr: Criminal[] = [];

I'm assuming you are using var so that means declaring it somewhere inside the func(),my suggestion would be use let instead of var.

If declaring it as c class property usse acces modifiers like private, public, protected.

Like it has been written before:

• Right Click on Bash on Ubuntu on Windows Icon if you have it on a Task Bar Shortcut Icon
• Click on Properties
• Select Options Tab on the Properties Window
• Check the QuickEditMode option
• Click Apply

Now you are able to open a new Bash Terminal and just use Right-Click to paste

In order to be able to copy from Terminal, Just use CTRL+M and this will enable you to select and copy selected Text.

A one liner shell script to remove a file if it already exist (based on Jindra Helcl's answer):

[ -f file ] && rm file

or with a variable:

#!/bin/bash

file="/path/to/file.ext"
[ -f $file ] && rm $file

You can loop throw the rows and columns, checking for nulls, keeping track of whether there's a null with a bool, then check it after looping through the table and handle it.

//your DataTable, replace with table get code
DataTable table = new DataTable();
bool tableHasNull = false;

foreach (DataRow row in table.Rows)
{
    foreach (DataColumn col in table.Columns)
    {
        //test for null here
        if (row[col] == DBNull.Value)
        {
            tableHasNull = true;
        }
    }
}

if (tableHasNull)
{
    //handle null in table
}

You can also come out of the foreach loop with a break statement e.g.

//test for null here
if (row[col] == DBNull.Value)
{
    tableHasNull = true;
    break;
}

To save looping through the rest of the table.

Try this..

select starttime,endtime, case
  when DATEDIFF(minute,starttime,endtime) < 60  then DATEDIFF(minute,starttime,endtime) 
  when DATEDIFF(minute,starttime,endtime) >= 60
  then '60,'+ cast( (cast(DATEDIFF(minute,starttime,endtime) as int )-60) as nvarchar(50) )
end from TestTable123416

All You need is DateDiff..

Here you can use my method for generating Random String

protected String getSaltString() {
        String SALTCHARS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
        StringBuilder salt = new StringBuilder();
        Random rnd = new Random();
        while (salt.length() < 18) { // length of the random string.
            int index = (int) (rnd.nextFloat() * SALTCHARS.length());
            salt.append(SALTCHARS.charAt(index));
        }
        String saltStr = salt.toString();
        return saltStr;

    }

The above method from my bag using to generate a salt string for login purpose.

You simply can find a matrix dimension by using Numpy:

import numpy as np

x = np.arange(24).reshape((6, 4))
x.ndim

output will be:

2

It means this matrix is a 2 dimensional matrix.

x.shape

Will show you the size of each dimension. The shape for x is equal to:

(6, 4)

Chapter 4.8 Block Structure in K&R's The C Programming Language 2.Ed.:

An automatic variable declared and initialized in a block is initialized each time the block is entered.

I might have missed seeing the relevant description in the book like:

An automatic variable declared and initialized in a block is allocated only one time before the block is entered.

But a simple test can prove the assumption held:

 #include <stdio.h>                                                                                                    

 int main(int argc, char *argv[]) {                                                                                    
     for (int i = 0; i < 2; i++) {                                                                                     
         for (int j = 0; j < 2; j++) {                                                                                 
             int k;                                                                                                    
             printf("%p\n", &k);                                                                                       
         }                                                                                                             
     }                                                                                                                 
     return 0;                                                                                                         
 }                                                                                                                     

Since you can not check with strok for upper or lowercase this works perfectly for checking the first word.

if (strtolower(strtok($text, " ")) == strtolower($firstword)){ .. }

This prints the number of processes whose basename is "chromium-browser":

ps -e -o args= | awk 'BEGIN{c=0}{
 if(!match($1,/^\[.*\]$/)){sub(".*/","",$1)} # Do not strip process names enclosed by square brackets.
 if($1==cmd){c++}
}END{print c}' cmd="chromium-browser"

If this prints "0", the process is not running. The command assumes process path does not contain breaking space. I have not tested this with suspended processes or zombie processes.

Tested using gwak as the awk alternative in Linux.

Here is a more versatile solution with some example usage:

#!/bin/sh
isProcessRunning() {
if [ "${1-}" = "-q" ]; then
 local quiet=1;
 shift
else
 local quiet=0;
fi
ps -e -o pid,args= | awk 'BEGIN{status=1}{
 name=$2
 if(name !~ /^\[.*\]$/){sub(".*/","",name)} # strip dirname, if process name is not enclosed by square brackets.
 if(name==cmd){status=0; if(q){exit}else{print $0}}
}END{exit status}' cmd="$1" q=$quiet
}

process='chromium-browser'

printf "Process \"${process}\" is "
if isProcessRunning -q "$process" 
 then printf "running.\n"
 else printf "not running.\n"; fi

printf "Listing of matching processes (PID and process name with command line arguments):\n"
isProcessRunning "$process"

Check if there is whitespace before = sign of excel formula

I realize this is a little old, but, yes it can be done. Some javascript to get you started:

viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0');

Just change the parts you need and Mobile Safari will respect the new settings.

Update:

If you don't already have the meta viewport tag in the source, you can append it directly with something like this:

var metaTag=document.createElement('meta');
metaTag.name = "viewport"
metaTag.content = "width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"
document.getElementsByTagName('head')[0].appendChild(metaTag);

Or if you're using jQuery:

$('head').append('<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">');

I had a similar problem with a log4j.xml file for a unit test, did all of the above. But figured out it was because I was only re-running a failed test....if I re-run the entire test class the correct file is picked up. This is under Intelli-j 9.0.4

To Convert file path in String to NSURL, observe the following code

var filePathUrl = NSURL.fileURLWithPath(path)

• Ctrl + A and then Ctrl+D. Doing this will detach you from the screen session which you can later resume by doing screen -r.

• You can also do: Ctrl+A then type :. This will put you in screen command mode. Type the command detach to be detached from the running screen session.

You have to create a ssh connection using port forwarding:

ssh -L 16006:127.0.0.1:6006 user@host

Then you run the tensorboard command:

tensorboard --logdir=/path/to/logs

Then you can easily access the tensorboard in your browser under:

localhost:16006/

Just close the Project you want to add , then drag and drop the file .

Node.js 8.0.0

Native async / await

Promisify

From this version, you can use native Node.js function from util library.

const fs = require('fs')
const { promisify } = require('util')

const readFileAsync = promisify(fs.readFile)
const writeFileAsync = promisify(fs.writeFile)

const run = async () => {
  const res = await readFileAsync('./data.json')
  console.log(res)
}

run()

Promise Wrapping

const fs = require('fs')

const readFile = (path, opts = 'utf8') =>
  new Promise((resolve, reject) => {
    fs.readFile(path, opts, (err, data) => {
      if (err) reject(err)
      else resolve(data)
    })
  })

const writeFile = (path, data, opts = 'utf8') =>
  new Promise((resolve, reject) => {
    fs.writeFile(path, data, opts, (err) => {
      if (err) reject(err)
      else resolve()
    })
  })

module.exports = {
  readFile,
  writeFile
}

...


// in some file, with imported functions above
// in async block
const run = async () => {
  const res = await readFile('./data.json')
  console.log(res)
}

run()

Advice

Always use try..catch for await blocks, if you don't want to rethrow exception upper.

As many others have answered: Java doesn't support user-defined operator overloading.

Maybe this is off-topic, but I want to comment on some things I read in some answers.

About readability.
Compare:

1. c = a + b
2. c = a.add(b)

Look again!
Which one is more readable?

A programming language that allows the creation of user-defined types, should allow them to act in the same way as the built-in types (or primitive types).

So Java breaks a fundamental principle of Generic Programming:
We should be able to interchange objects of built-in types with objects of user-defined types.
(You may be wondering: "Did he say 'objects of built-in'?". Yes, see here.)

About String concatenation:

Mathematicians use the symbol + for commutative operations on sets.
So we can be sure that a + b = b + a.
String concatenation (in most programming languages) doesn't respect this common mathematical notation.

a := "hello";
b := "world";
c := (a + b = b + a);

or in Java:

String a = "hello";
String b = "world";
boolean c = (a + b).equals(b + a);

Extra:
Notice how in Java equality and identity are confused. The == (equality) symbol means:
a. Equality for primitive types.
b. Identity-check for user-defined types, therefore, we are forced to use the function equals() for equality.
But... What has this to do with operator overloading?
If the language allows the operator overloading the user could give the proper meaning to the equality operator.

Use this

@Table (name = "Test", schema = "\"schema\"")

insteade of @Table (name = "Test", schema = "schema")

If you are on postgresql the request is :

SELECT * FROM "schema".test 

not :

SELECT * FROM schema.test

PS: Test is a table

I suggest you use a HiddenField inside template field use FindControl to find this field.

ie:

ASPX

                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:HiddenField ID="hfFname" runat="server" Value='<%# Eval("FileName") %>' />
                    </ItemTemplate>
                </asp:TemplateField>

Code behind

protected void gvAttachments_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        GridView gv1 = (GridView)sender;
        GridViewRow gvr1 = (GridViewRow)gv1.Rows[e.RowIndex];

        //get hidden field value and not directly from the GridviewRow, as that will be null or empty!
        HiddenField hf1 = (HiddenField)gvr1.FindControl("hfFname");
        if (hf1 != null)
        {
           ..
        }
    }

Potential answer for SQL Server

Interesting I just ran a test using LinqPad with SQL Server which should be just running Linq to SQL underneath and it generates the following SQL statement.

Records .Where(r => r.Name.Contains("lkjwer--_~[]"))

-- Region Parameters
DECLARE @p0 VarChar(1000) = '%lkjwer--~_~~~[]%'
-- EndRegion
SELECT [t0].[ID], [t0].[Name]
FROM [RECORDS] AS [t0]
WHERE [t0].[Name] LIKE @p0 ESCAPE '~'

So I haven't tested it yet but it looks like potentially the ESCAPE '~' keyword may allow for automatic escaping of a string for use within a like expression.

Try

os.path.getsize(filename)

It should return the size of a file, reported by os.stat().

How about str.gsub("subString", "") Check out the Ruby Doc

This looks like what you actually want. It applies the same approach of this answer to your specific case:

import matplotlib.pyplot as plt

fig, ax = plt.subplots(nrows=3, ncols=3, sharex=True, sharey=True, figsize=(6, 6))

fig.text(0.5, 0.04, 'common X', ha='center')
fig.text(0.04, 0.5, 'common Y', va='center', rotation='vertical')

Compiler could align members in structures to achieve maximum performance on the certain platform. #pragma pack directive allows you to control that alignment. Usually you should leave it by default for optimum performance. If you need to pass a structure to the remote machine you generally will use #pragma pack 1 to exclude any unwanted alignment.

webpack solution

If you got this error while working in React with webpack and HMR.

You need to create template index.html and save it in src folder:

<html>
    <body>
       <div id="root"></root>
    </body>
</html>

Now when we have template with id="root" we need to tell webpack to generate index.html which will mirror our index.html file.

To do that:

plugins: [
    new HtmlWebpackPlugin({
        title: "Application name",
        template: './src/index.html'
    })
],

template property will tell webpack how to build index.html file.

The obj directory is for intermediate object files and other transient data files that are generated by the compiler or build system during a build. The bin directory is the directory that final output binaries (and any dependencies or other deployable files) will be written to.

You can change the actual directories used for both purposes within the project settings, if you like.

what may be happening is your company decrypts certain traffic and re-encrypts it with their certificate (which you probably already have in your keychain or trusted root certificates)

if you're using node 7 or later I've found this fix to be compatible with node and node-gyp (for Windows you'll need to do this differently, but you basically just need to add this environment variable):

export NODE_EXTRA_CA_CERTS="absolute_path_to_your_certificates.pem" (in Windows you may need to remove the quotes - see comments)

the pem file can have multiple certificates: https://nodejs.org/api/cli.html#cli_node_extra_ca_certs_file

make sure your certificates are in proper pem format (you need real line breaks not literal \n)

I couldn't seem to get it to work with relative paths (. or ~)

This fix basically tells npm and node-gyp to use the check against the regular CAs, but also allow this certificate when it comes across it

Ideally you would be able to use your system's trusted certificates, but unfortunately this is not the case.

In JavaScript 1.8.5, Object.getOwnPropertyNames returns an array of all properties found directly upon a given object.

Object.getOwnPropertyNames ( obj )

and another method Object.keys, which returns an array containing the names of all of the given object's own enumerable properties.

Object.keys( obj )

I used forEach to list values and keys in obj, same as for (var key in obj) ..

Object.keys(obj).forEach(function (key) {
      console.log( key , obj[key] );
});

This all are new features in ECMAScript , the mothods getOwnPropertyNames, keys won't supports old browser's.

Go to the starting line and type ma (mark "a"). Then go to the last line and enter d'a (delete to mark "a").

That will delete all lines from the current to the marked one (inclusive). It's also compatible with vi as well as vim, on the off chance that your environment is not blessed with the latter.

The error in the Google DevTools are caused Google extensions.

1. I clicked on my Google icon in the browser
2. created a guest profile at the bottom of the popup window.
3. I then pasted my localhost address and voila!!

An NDF file is a user defined secondary database file of Microsoft SQL Server with an extension .ndf, which store user data. Moreover, when the size of the database file growing automatically from its specified size, you can use .ndf file for extra storage and the .ndf file could be stored on a separate disk drive. Every NDF file uses the same filename as its corresponding MDF file. We cannot open an .ndf file in SQL Server Without attaching its associated .mdf file.

It depends on whether you are submitting the form normally or via an AJAX call. You can find lots of information at jquery.com, including documentation with examples. For submitting a form normally, check out the submit() method to at that site. For AJAX, there are many different possibilities, though you probably want to use either the ajax() or post() methods. Note that post() is really just a convenient way to call the ajax() method with a simplified, and limited, interface.

A critical resource, one I use every day, that you should bookmark is How jQuery Works. It has tutorials on using jQuery and the left-hand navigation gives access to all of the documentation.

Examples:

Normal

$('form#myForm').submit();

AJAX

$('input#submitButton').click( function() {
    $.post( 'some-url', $('form#myForm').serialize(), function(data) {
         // ... do something with response from server
       },
       'json' // I expect a JSON response
    );
});

$('input#submitButton').click( function() {
    $.ajax({
        url: 'some-url',
        type: 'post',
        dataType: 'json',
        data: $('form#myForm').serialize(),
        success: function(data) {
                   // ... do something with the data...
                 }
    });
});

Note that the ajax() and post() methods above are equivalent. There are additional parameters you can add to the ajax() request to handle errors, etc.

 for(int i = 0; i < strlen(Name); i++ )
{
    if(Name[i] == '\n') Name[i] = '\0';
}

You should give it a try. This code basically loop through the string until it finds the '\n'. When it's found the '\n' will be replaced by the null character terminator '\0'

Note that you are comparing characters and not strings in this line, then there's no need to use strcmp():

if(Name[i] == '\n') Name[i] = '\0';

since you will be using single quotes and not double quotes. Here's a link about single vs double quotes if you want to know more

I had this issue too. The way I solved it was the following:

1. Delete the google-play-services_lib library-project.
2. Remove the (now invalid) google-play-services_lib reference in [your project] > Properties > Android.
3. Imported the google-play-services_lib library-project from android-sdk-x/extras/google_play_services/libproject. When you import a project, you get the option "Copy project into workspace". UNCHECK IT.
4. Add the (now valid) google-play-services_lib reference to your project with [your project] > Properties > Android.

This did the trick for me. I hope it helps you too!

With this code, you only change rows backcolor where columname value is null other rows color still the default one.

       foreach (DataGridViewRow row in dataGridView1.Rows)
                {
                    if (row.Cells["columnname"].Value != null)
                    {
                        dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.MistyRose;
                    }
                 }

Our aim is basically to check whether 2 arrays are equal sets. set is the mathematically defined set. Fastest sorting asymptotically takes O(nlog(n)) time. So If you sort an array, it would take at least O(nlog(n)) time. But you can do this task faster, which asymptotically takes O(n) time (average case not worst case) with a dictionary data structure. In JS, a dictionary is simply an object with keys and values.

/** assumes array elements are primitive types
* check whether 2 arrays are equal sets.
* @param  {} a1 is an array
* @param  {} a2 is an array
*/
function areArraysEqualSets(a1, a2) {
  const superSet = {};
  for (const i of a1) {
    const e = i + typeof i;
    superSet[e] = 1;
  }

  for (const i of a2) {
    const e = i + typeof i;
    if (!superSet[e]) {
      return false;
    }
    superSet[e] = 2;
  }

  for (let e in superSet) {
    if (superSet[e] === 1) {
      return false;
    }
  }

  return true;
}

Note that this function works with arrays of primitive types and assumes a1 and a2 are arrays.

Calling the isHTML() method after the instance Body property (I mean $mail->Body) has been set solved the problem for me:

$mail->Subject = $Subject;
$mail->Body    = $Body;
$mail->IsHTML(true);       // <=== call IsHTML() after $mail->Body has been set.

If You want to have a reference to this variable across the whole project, create somewhere d.ts file, e.g. globals.d.ts. Fill it with your global variables declarations, e.g.:

declare const BootBox: 'boot' | 'box';

Now you can reference it anywhere across the project, just like that:

const bootbox = BootBox;

Here's an example.

You could:

SELECT COALESCE(SUM(columnA), 0) FROM my_table WHERE columnB = 1
INTO res;

This happens to work, because your query has an aggregate function and consequently always returns a row, even if nothing is found in the underlying table.

Plain queries without aggregate would return no row in such a case. COALESCE would never be called and couldn't save you. While dealing with a single column we can wrap the whole query instead:

SELECT COALESCE( (SELECT columnA FROM my_table WHERE ID = 1), 0)
INTO res;

Works for your original query as well:

SELECT COALESCE( (SELECT SUM(columnA) FROM my_table WHERE columnB = 1), 0)
INTO res;

For Data access you can use OData. Here is a demo where Scott Hanselman creates an OData front end to StackOverflow database in 30 minutes, with XML and JSON access: Creating an OData API for StackOverflow including XML and JSON in 30 minutes.

For administrative access, like phpMyAdmin package, there is no well established one. You may give a try to IIS Database Manager.

Perhaps a little off topic, just be informed that these kind of messages can also be seen when you are debugging your code with a breakpoint inside an async function like setTimeout like below:

[Violation] 'setTimeout' handler took 43129ms

That number (43129ms) depends on how long you stop in your async function

list object in python does not have 'shape' attribute because 'shape' implies that all the columns (or rows) have equal length along certain dimension.

Let's say list variable a has following properties: a = [[2, 3, 4] [0, 1] [87, 8, 1]]

it is impossible to define 'shape' for variable 'a'. That is why 'shape' might be determined only with 'arrays' e.g.

b = numpy.array([[2, 3, 4]
                [0, 1, 22]
                [87, 8, 1]])

I hope this explanation clarifies well this question.

Spring considers that anything behind the last dot is a file extension such as .jsonor .xml and trucate it to retrieve your parameter.

So if you have /somepath/{variable} :

• /somepath/param, /somepath/param.json, /somepath/param.xml or /somepath/param.anything will result in a param with value param
• /somepath/param.value.json, /somepath/param.value.xml or /somepath/param.value.anything will result in a param with value param.value

if you change your mapping to /somepath/{variable:.+} as suggested, any dot, including the last one will be consider as part of your parameter :

• /somepath/param will result in a param with value param
• /somepath/param.json will result in a param with value param.json
• /somepath/param.xml will result in a param with value param.xml
• /somepath/param.anything will result in a param with value param.anything
• /somepath/param.value.json will result in a param with value param.value.json
• ...

If you don't care of extension recognition, you can disable it by overriding mvc:annotation-driven automagic :

<bean id="handlerMapping"
      class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="contentNegotiationManager" ref="contentNegotiationManager"/>
    <property name="useSuffixPatternMatch" value="false"/>
</bean>

So, again, if you have /somepath/{variable} :

• /somepath/param, /somepath/param.json, /somepath/param.xml or /somepath/param.anything will result in a param with value param
• /somepath/param.value.json, /somepath/param.value.xml or /somepath/param.value.anything will result in a param with value param.value

note : the difference from the default config is visible only if you have a mapping like somepath/something.{variable}. see Resthub project issue

if you want to keep extension management, since Spring 3.2 you can also set the useRegisteredSuffixPatternMatch property of RequestMappingHandlerMapping bean in order to keep suffixPattern recognition activated but limited to registered extension.

Here you define only json and xml extensions :

<bean id="handlerMapping"
      class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="contentNegotiationManager" ref="contentNegotiationManager"/>
    <property name="useRegisteredSuffixPatternMatch" value="true"/>
</bean>

<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false"/>
    <property name="favorParameter" value="true"/>
    <property name="mediaTypes">
        <value>
            json=application/json
            xml=application/xml
        </value>
    </property>
</bean>

Note that mvc:annotation-driven accepts now a contentNegotiation option to provide a custom bean but the property of RequestMappingHandlerMapping has to be changed to true (default false) (cf. https://jira.springsource.org/browse/SPR-7632).

For that reason, you still have to override the all mvc:annotation-driven configuration. I opened a ticket to Spring to ask for a custom RequestMappingHandlerMapping : https://jira.springsource.org/browse/SPR-11253. Please vote if you are intereted in.

While overriding, be carreful to consider also custom Execution management overriding. Otherwise, all your custom Exception mappings will fail. You will have to reuse messageCoverters with a list bean :

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean" />

<util:list id="messageConverters">

Summary (@Freek Wiekmeijer, @gtalarico) other's answer:

Logic of Login

• Many resource(pages, api) need authentication, then can access, otherwise 405 Not Allowed
• Common authentication=grant access method are:
  • cookie
  • auth header
    • Basic xxx
    • Authorization xxx

How use cookie in requests to auth

1. first get/generate cookie
2. send cookie for following request

• manual set cookie in headers
• auto process cookie by requests's
  • session to auto manage cookies
  • response.cookies to manually set cookies

use requests's session auto manage cookies

curSession = requests.Session() 
# all cookies received will be stored in the session object

payload={'username': "yourName",'password': "yourPassword"}
curSession.post(firstUrl, data=payload)
# internally return your expected cookies, can use for following auth

# internally use previously generated cookies, can access the resources
curSession.get(secondUrl)

curSession.get(thirdUrl)

manually control requests's response.cookies

payload={'username': "yourName",'password': "yourPassword"}
resp1 = requests.post(firstUrl, data=payload)

# manually pass previously returned cookies into following request
resp2 = requests.get(secondUrl, cookies= resp1.cookies)

resp3 = requests.get(thirdUrl, cookies= resp2.cookies)

Edit : for an in-depth understanding of the mental model of decorators, take a look at this awesome Pycon Talk. well worth the 30 minutes.

One way of thinking about decorators with arguments is

@decorator
def foo(*args, **kwargs):
    pass

translates to

foo = decorator(foo)

So if the decorator had arguments,

@decorator_with_args(arg)
def foo(*args, **kwargs):
    pass

translates to

foo = decorator_with_args(arg)(foo)

decorator_with_args is a function which accepts a custom argument and which returns the actual decorator (that will be applied to the decorated function).

I use a simple trick with partials to make my decorators easy

from functools import partial

def _pseudo_decor(fun, argument):
    def ret_fun(*args, **kwargs):
        #do stuff here, for eg.
        print ("decorator arg is %s" % str(argument))
        return fun(*args, **kwargs)
    return ret_fun

real_decorator = partial(_pseudo_decor, argument=arg)

@real_decorator
def foo(*args, **kwargs):
    pass

Update:

Above, foo becomes real_decorator(foo)

One effect of decorating a function is that the name foo is overridden upon decorator declaration. foo is "overridden" by whatever is returned by real_decorator. In this case, a new function object.

All of foo's metadata is overridden, notably docstring and function name.

>>> print(foo)
<function _pseudo_decor.<locals>.ret_fun at 0x10666a2f0>

functools.wraps gives us a convenient method to "lift" the docstring and name to the returned function.

from functools import partial, wraps

def _pseudo_decor(fun, argument):
    # magic sauce to lift the name and doc of the function
    @wraps(fun)
    def ret_fun(*args, **kwargs):
        # pre function execution stuff here, for eg.
        print("decorator argument is %s" % str(argument))
        returned_value =  fun(*args, **kwargs)
        # post execution stuff here, for eg.
        print("returned value is %s" % returned_value)
        return returned_value

    return ret_fun

real_decorator1 = partial(_pseudo_decor, argument="some_arg")
real_decorator2 = partial(_pseudo_decor, argument="some_other_arg")

@real_decorator1
def bar(*args, **kwargs):
    pass

>>> print(bar)
<function __main__.bar(*args, **kwargs)>

>>> bar(1,2,3, k="v", x="z")
decorator argument is some_arg
returned value is None

This is a faster/simpler (and prototypical) variation of the function that Josh posted:

String.prototype.format = String.prototype.f = function() {
    var s = this,
        i = arguments.length;

    while (i--) {
        s = s.replace(new RegExp('\\{' + i + '\\}', 'gm'), arguments[i]);
    }
    return s;
};

Usage:

'Added {0} by {1} to your collection'.f(title, artist)
'Your balance is {0} USD'.f(77.7) 

I use this so much that I aliased it to just f, but you can also use the more verbose format. e.g. 'Hello {0}!'.format(name)

How about storing the new options in a variable, and then using .html(variable) to replace the data in the container?

Using java 8:

public static <T> List<T> removeDuplicates(List<T> list) {
    return list.stream().collect(Collectors.toSet()).stream().collect(Collectors.toList());
}

yo can extend your JS with a select method like this

Array.prototype.select = function(closure){
    for(var n = 0; n < this.length; n++) {
        if(closure(this[n])){
            return this[n];
        }
    }

    return null;
};

now you can use this:

var x = [1,2,3,4];

var a = x.select(function(v) {
    return v == 2;
});

console.log(a);

or for objects in a array

var x = [{id: 1, a: true},
    {id: 2, a: true},
    {id: 3, a: true},
    {id: 4, a: true}];

var a = x.select(function(obj) {
    return obj.id = 2;
});

console.log(a);

To set a default value to a column, try this:

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status SET DEFAULT 'default value'

If you change .bash_profile, it only applies to new Terminal sessions.

To apply it to an existing session, run source ~/.bash_profile. You can run any Bash script this way - think of executing source as the same as typing commands in the Terminal window (from the specified script).

More info: How to reload .bash_profile from the command line?

Bonus: You can make environment variables available to OSX applications - not just the current Bash session but apps like Visual Studio Code or IntelliJ - using launchctl setenv GOPATH "${GOPATH:-}"

Here is a simple method to plot two histograms, with their bars side-by-side, on the same plot when the data has different sizes:

def plotHistogram(p, o):
    """
    p and o are iterables with the values you want to 
    plot the histogram of
    """
    plt.hist([p, o], color=['g','r'], alpha=0.8, bins=50)
    plt.show()

This question is very old, but I found myself studying for a Microsoft Certification, and in the study book it was suggested to use:

oldElement.replaceNode(newElement)

I looked it up and it seems to only be supported in IE. Doh..

I thought I'd just add it here as a funny side note ;)

For whoever is still looking for a totally transparent panel, I found a nice solution in this blog by William Smash who in turn has taken it from Tobias Hertkorn on his T# blog. I thought its worth posting it as an answer here.

C# code:

public class TransparentPanel : Panel
{
    protected override CreateParams CreateParams 
    {            
        get {
            CreateParams cp =  base.CreateParams;
            cp.ExStyle |= 0x00000020; // WS_EX_TRANSPARENT
            return cp;
            }
    }
    protected override void OnPaintBackground(PaintEventArgs e) 
    {
        //base.OnPaintBackground(e);
    }
}

VB.Net code:

Public Class TransparentPanel
Inherits Panel
    Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
        Get
            Dim cp As CreateParams = MyBase.CreateParams
            cp.ExStyle = cp.ExStyle Or &H20 ''#WS_EX_TRANSPARENT
            Return cp
        End Get
    End Property
    Protected Overrides Sub OnPaintBackground(ByVal e As System.Windows.Forms.PaintEventArgs)
    ''#MyBase.OnPaintBackground(e)
    End Sub
End Class

When the following is invoked within a shell script, the terminal prompt will appear just like many other unix commands do when they are run with sudo:

# get superuser password
user=$(whoami)
stty -echo
read -p "[sudo] password for $user: " password
stty echo
echo ""

Then you can use $password as needed.

Data transfer between two platform requires a common data format. JSON is a common global format to send cross platform data.

drawChart(600/50, JSON.parse('<?php echo json_encode($day); ?>'), JSON.parse('<?php echo json_encode($week); ?>'), JSON.parse('<?php echo json_encode($month); ?>'), JSON.parse('<?php echo json_encode(createDatesArray(cal_days_in_month(CAL_GREGORIAN, date('m',strtotime('-1 day')), date('Y',strtotime('-1 day'))))); ?>'))

This is the answer to your question. The answer may look very complex. You can see a simple example describing the communication between server side and client side here

$employee = array(
 "employee_id" => 10011,
   "Name" => "Nathan",
   "Skills" =>
    array(
           "analyzing",
           "documentation" =>
            array(
              "desktop",
                "mobile"
             )
        )
);

Conversion to JSON format is required to send the data back to client application ie, JavaScript. PHP has a built in function json_encode(), which can convert any data to JSON format. The output of the json_encode function will be a string like this.

{
    "employee_id": 10011,
    "Name": "Nathan",
    "Skills": {
        "0": "analyzing",
        "documentation": [
            "desktop",
            "mobile"
        ]
    }
}

On the client side, success function will get the JSON string. Javascript also have JSON parsing function JSON.parse() which can convert the string back to JSON object.

$.ajax({
        type: 'POST',
        headers: {
            "cache-control": "no-cache"
        },
        url: "employee.php",
        async: false,
        cache: false,
        data: {
            employee_id: 10011
        },
        success: function (jsonString) {
            var employeeData = JSON.parse(jsonString); // employeeData variable contains employee array.
    });

This is a pretty old question...but if your use case here is to simply send a particular HTML page to the browser on an ad hoc basis, I would use something simple like this:

var http = require('http')
,       fs = require('fs');

var server = http.createServer(function(req, res){
  var stream = fs.createReadStream('test.html');
  stream.pipe(res);
});
server.listen(7000);

Similar to other answers, this error can be experienced when there are no sites configured to use SSL.

I had the error when I upgraded from Debian Wheezy to Debian Jessie. The new version of Apache requires a site configuration file ending in .conf. Because my configuration file didn't, it was being ignored, and there were no others configured to serve SSL connections.

With JUnit5 and @DataJpaTest test will look like (kotlin code):

@DataJpaTest
@ExtendWith(value = [SpringExtension::class])
class ActivityJpaTest {

    @Autowired
    lateinit var entityManager: TestEntityManager

    @Autowired
    lateinit var myEntityRepository: MyEntityRepository

    @Test
    fun shouldSaveEntity() {
        // when
        val savedEntity = myEntityRepository.save(MyEntity(1, "test")

        // then 
        Assertions.assertNotNull(entityManager.find(MyEntity::class.java, savedEntity.id))
    }
}

You could use TestEntityManager from org.springframework.boot.test.autoconfigure.orm.jpa.TestEntityManager package in order to validate entity state.

Add this to your code :

instance.setDatapath("C:\\somepath\\tessdata");

instance.setLanguage("eng");

You need to make sure that you add forward slash before your link to socket.io:

<script src="/socket.io/socket.io.js"></script>

Then in the view/controller just do:

var socket = io.connect()

That should solve your problem.

While zolley's answer is perfectly right for the question, here's a more general solution for any range, plus explanation:

    =COUNTIF($A$1:$C$50, INDIRECT(ADDRESS(ROW(), COLUMN(), 4))) > 1

Please note that in this example I will be using the range A1:C50. The first parameter ($A$1:$C$50) should be replaced with the range on which you would like to highlight duplicates!

to highlight duplicates:

1. Select the whole range on which the duplicate marking is wanted.
2. On the menu: Format > Conditional formatting...
3. Under Apply to range, select the range to which the rule should be applied.
4. In Format cells if, select Custom formula is on the dropdown.
5. In the textbox insert the given formula, adjusting the range to match step (3).

Why does it work?

COUNTIF(range, criterion), will compare every cell in range to the criterion, which is processed similarly to formulas. If no special operators are provided, it will compare every cell in the range with the given cell, and return the number of cells found to be matching the rule (in this case, the comparison). We are using a fixed range (with $ signs) so that we always view the full range.

The second block, INDIRECT(ADDRESS(ROW(), COLUMN(), 4)), will return current cell's content. If this was placed inside the cell, docs will have cried about circular dependency, but in this case, the formula is evaluated as if it was in the cell, without changing it.

ROW() and COLUMN() will return the row number and column number of the given cell respectively. If no parameter is provided, the current cell will be returned (this is 1-based, for example, B3 will return 3 for ROW(), and 2 for COLUMN()).

Then we use: ADDRESS(row, column, [absolute_relative_mode]) to translate the numeric row and column to a cell reference (like B3. Remember, while we are inside the cell's context, we don't know it's address OR content, and we need the content in order to compare with). The third parameter takes care for the formatting, and 4 returns the formatting INDIRECT() likes.

INDIRECT(), will take a cell reference and return its content. In this case, the current cell's content. Then back to the start, COUNTIF() will test every cell in the range against ours, and return the count.

The last step is making our formula return a boolean, by making it a logical expression: COUNTIF(...) > 1. The > 1 is used because we know there's at least one cell identical to ours. That's our cell, which is in the range, and thus will be compared to itself. So to indicate a duplicate, we need to find 2 or more cells matching ours.

                <asp:Button ID="btnPost" CssClass="submitButton" Text="Comment" runat="server" CommandName="Comment" CommandArgument='<%#Eval("ScrapId")+","+ Eval("UserId")%>' />

                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

first bind the GridView.

public void GetData()
{
   //bind ur GridView
   GridViewUserScraps.DataSource = dt;
   GridViewUserScraps.DataBind();
}

protected void GridViews_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Comment")
    {
        string[] commandArgs = e.CommandArgument.ToString().Split(new char[] { ',' });
        string scrapid = commandArgs[0];
        string uid = commandArgs[1];
    }
}

This is my solution is use display: inline

Some text <div class="dropdown" style="display:inline">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
    Dropdown
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
    <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
  </ul>
</div> is here

There's no constants in JavaScript, but to declare a literal all you have to do is:

var myString = "Hello World";

I'm not sure what you mean by store them in a resource file; that's not a JavaScript concept.

So, I had this code:

<div class="dropdown-select-wrapper" *ngIf="contentData">
    <button mat-stroked-button [disableRipple]="true" class="mat-button" (click)="openSelect()" [ngClass]="{'only-icon': !contentData?.buttonText?.length}">
      <i *ngIf="contentData.iconClassInfo" class="dropdown-icon {{contentData.iconClassInfo.name}}"></i>
      <span class="button-text" *ngIf="contentData.buttonText">{{contentData.buttonText}}</span>
    </button>
    <mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();">
      <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
        {{option[contentData.optionsStructure.keyName]}}
      </mat-option>
    </mat-select>
  </div>

Here I was using standalone formControl, and I was getting the error we are talking about, which made no sense for me, since I wasn't working with formgroups or formarrays... it only disappeared when I added the *ngIf to the select it self, so is not being used before it actually exists. That's what solved the issue in my case.

<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();" *ngIf="theFormControl">
          <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
            {{option[contentData.optionsStructure.keyName]}}
          </mat-option>
        </mat-select>

From SQL Server 2012, we can use OFFSET and FETCH NEXT Clause to achieve the pagination.

Try this, for SQL Server:

In the SQL Server 2012 a new feature was added in the ORDER BY clause, to query optimization of a set data, making work easier with data paging for anyone who writes in T-SQL as well for the entire Execution Plan in SQL Server.

Below the T-SQL script with the same logic used in the previous example.

--CREATING A PAGING WITH OFFSET and FETCH clauses IN "SQL SERVER 2012"
DECLARE @PageNumber AS INT, @RowspPage AS INT
SET @PageNumber = 2
SET @RowspPage = 10 
SELECT ID_EXAMPLE, NM_EXAMPLE, DT_CREATE
FROM TB_EXAMPLE
ORDER BY ID_EXAMPLE
OFFSET ((@PageNumber - 1) * @RowspPage) ROWS
FETCH NEXT @RowspPage ROWS ONLY;

TechNet: Paging a Query with SQL Server

It couldn't be simpler than this:

    public SomeClass Clone () {

        var clonedJson = JsonConvert.SerializeObject (this);

        return JsonConvert.DeserializeObject<SomeClass> (clonedJson);
    }

Just serialize any object to a JSON string and then deserialize it. This will do a deep copy...

If you are using the windows CMD you can use this command to create a database using sqlite3

C:\sqlite3.exe DBNAME.db ".read DBSCRIPT.sql"

If you haven't a database with that name sqlite3 will create one, and if you already have one, it will run it anyways but with the "TABLENAME already exists" error, I think you can also use this command to change an already existing database (but im not sure)

With WAMP it's all pretty easy

WAMP Icon > PHP > PHP Settings > upload_max_filesize = nM > n = (2M, 4M, 8M, 16M, 32M, 64M, 128M, 256M, 512M, or Choose (custom)).

Service(s) reload automatically.

But, if you truly have no access to the server, you might want to explore writing a chunking API.

The simplest way to this is:

<input type="checkbox" class="special" onclick="event.preventDefault();" checked />

This will prevent the user from being able to deselect this checkbox and it will still submit its value when the form is submitted. Remove checked if you want the user to not be able to select this checkbox.

Also, you can then use javascript to clear the onclick once a certain condition has been met (if that's what you're after). Here's a down-and-dirty fiddle showing what I mean. It's not perfect, but you get the gist.

http://jsfiddle.net/vwUUc/

What about this?
Destructor is not called if an exception is thrown from the constructor, so I have to call it manually to destroy handles that have been created in the constructor before the exception.

class MyClass {
  HANDLE h1,h2;
  public:
  MyClass() {
    // handles have to be created first
    h1=SomeAPIToCreateA();
    h2=SomeAPIToCreateB();        
    try {
      ...
      if(error) {
        throw MyException();
      }
    }
    catch(...) {
      this->~MyClass();
      throw;
    }
  }
  ~MyClass() {
    SomeAPIToDestroyA(h1);
    SomeAPIToDestroyB(h2);
  }
};

You can also try using multiprocessing.Process with daemon=True; the process.start() method does not block and you can return a response/status immediately to the caller while your expensive function executes in the background.

I experienced similar problem while working with falcon framework and using daemon process helped.

You'd need to do the following:

from multiprocessing import Process

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    heavy_process = Process(  # Create a daemonic process with heavy "my_func"
        target=my_func,
        daemon=True
    )
    heavy_process.start()
    return Response(
        mimetype='application/json',
        status=200
    )

# Define some heavy function
def my_func():
    time.sleep(10)
    print("Process finished")

You should get a response immediately and, after 10s you should see a printed message in the console.

NOTE: Keep in mind that daemonic processes are not allowed to spawn any child processes.

As I needed to use this feature for my latest project (at one point we updated from 1.10.19), just to keep the users (that are already using the mockito-core version 2.1.0 or greater) up to date, the static methods from the above answers should be taken from ArgumentMatchers class:

import static org.mockito.ArgumentMatchers.isA;
import static org.mockito.ArgumentMatchers.any;

Please keep this in mind if you are planning to keep your Mockito artefacts up to date as possibly starting from version 3, this class may no longer exist:

As per 2.1.0 and above, Javadoc of org.mockito.Matchers states:

Use org.mockito.ArgumentMatchers. This class is now deprecated in order to avoid a name clash with Hamcrest * org.hamcrest.Matchers class. This class will likely be removed in version 3.0.

I have written a little article on mockito wildcards if you're up for further reading.

I don't think it's 64/32 bit error. My Dev machine and DB server are 32bit. But I could make it work. I had to set Delay Validation property of Data Flow tasks to TRUE.

var functionX = function() {
  var self = this;
  var functionY = function(y) {
    // If we call "this" in here, we get a reference to functionY,
    // but if we call "self" (defined earlier), we get a reference to function X.
  }
}

edit: in spite of, nested functions within an object takes on the global window object rather than the surrounding object.

Oracle recommends to add the @Path annotation to all types to be injected when combining JAX-RS with CDI: http://docs.oracle.com/javaee/7/tutorial/jaxrs-advanced004.htm Though this is far from perfect (e.g. you will get warning from Jersey on startup), I decided to take this route, which saves me from maintaining all supported types within a binder.

Example:

@Singleton
@Path("singleton-configuration-service")
public class ConfigurationService {
  .. 
}

@Path("my-path")
class MyProvider {
  @Inject ConfigurationService _configuration;

  @GET
  public Object get() {..}
}

In your application context, change the bean with id from emf to entityManagerFactory:

    </property>

    <property name="persistenceProvider">
        <bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean>

Okay, I'm writing this answer by extending wmky's answer above & also, assuming that you've configured mysql for your metastore instead of derby.

select PART_NAME FROM PARTITIONS WHERE TBL_ID=(SELECT TBL_ID FROM TBLS WHERE TBL_NAME='<table_name>');

The above query gives you all possible values of the partition columns.

Example:

hive> desc clicks_fact;
OK
time                    timestamp

file_date               varchar(8)                                  

# Partition Information      
# col_name              data_type               comment             

day                     date                                        
file_date               varchar(8)                                  
Time taken: 1.075 seconds, Fetched: 28 row(s)

I'm going to fetch the values of partition columns.

Note: JOIN table DBS ON DB_ID when there is a DB involved (i.e, when, multiple DB's have same table_name)

IDLE TO VISUAL STUDIO USERS: I ran into this problem as well when moving code directly from IDLE to Visual Studio. When you press tab IDLE adds 4 spaces instead of a tab. In IDLE, hit Ctl+A to select all of the code and go to Format>Tabify Region. Now move the code to visual studio and most errors should be fixed. Every so often there will be code that is off-tab, just fix it manually.

if you have installed NDK succesfully then start with it sample application

if you are interested another ways of this then may this will help

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?

here you can see NestedVM

NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.

Example: Cross compile Hello world C program and run it on android

I believe java gleans this from the environment variables in which it was launched, so you'll need to make sure your LANG and LC_* environment variables are set appropriately.

The locale manpage has full info on said environment variables.

Going on the assumption you're using TNSNAMES naming, here's a couple of things to do:

• Create/modify the tnsnames.ora file in the network/admin subdirectory associated with OraHome90 to include an entry for your oracle database:

> SERVICENAME_alias =
>    (DESCRIPTION =
>     (ADDRESS = (PROTOCOL = TCP)(HOST = HOST.XYZi.com)(PORT = 1521))
>     (CONNECT_DATA = (SERVICE_NAME = SERVICENAME))

This is assuming you're using the standard Oracle port of 1521. Note that servicename_alias can be any name you want to use on the local system. You may also find that you need to specify (SID = SERVICENAME) instead of (SERVICENAME=SERVICENAME).

• Execute tnsping servicename_alias to verify connectivity. Get this working before going any further. This will tell you if you're past the 12154 error.
• Assuming a good connection, create an ODBC DSN using the control panel, specifying the ODBC driver for Oracle of your choice (generally there's a Microsoft ODBC driver at least, and it should work adequately as a proof of concept). I'll assume the name you gave of DATASOURCE. Use the servicename_alias as the Server name in the ODBC configuration.
• At this point you should be able to connect to your database via Access. I am not a VB programmer, but I know you should be able to go to File->Get External Data->Link Tables and connect to your ODBC source. I would assume your code would work as well.

The concept of interval notation comes up in both Mathematics and Computer Science. The Mathematical notation [, ], (, ) denotes the domain (or range) of an interval.

• The brackets [ and ] means:

  1. The number is included,
  2. This side of the interval is closed,

• The parenthesis ( and ) means:

  1. The number is excluded,
  2. This side of the interval is open.

An interval with mixed states is called "half-open".

For example, the range of consecutive integers from 1 .. 10 (inclusive) would be notated as such:

• [1,10]

Notice how the word inclusive was used. If we want to exclude the end point but "cover" the same range we need to move the end-point:

• [1,11)

For both left and right edges of the interval there are actually 4 permutations:

(1,10) =   2,3,4,5,6,7,8,9       Set has  8 elements
(1,10] =   2,3,4,5,6,7,8,9,10    Set has  9 elements
[1,10) = 1,2,3,4,5,6,7,8,9       Set has  9 elements
[1,10] = 1,2,3,4,5,6,7,8,9,10    Set has 10 elements

How does this relate to Mathematics and Computer Science?

Array indexes tend to use a different offset depending on which field are you in:

• Mathematics tends to be one-based.
• Certain programming languages tends to be zero-based, such as C, C++, Javascript, Python, while other languages such as Mathematica, Fortran, Pascal are one-based.

These differences can lead to subtle fence post errors, aka, off-by-one bugs when implementing Mathematical algorithms such as for-loops.

Integers

If we have a set or array, say of the first few primes [ 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 ], Mathematicians would refer to the first element as the 1st absolute element. i.e. Using subscript notation to denote the index:

• a₁ = 2
• a₂ = 3
• :
• a₁₀ = 29

Some programming languages, in contradistinction, would refer to the first element as the zero'th relative element.

• a[0] = 2
• a[1] = 3
• :
• a[9] = 29

Since the array indexes are in the range [0,N-1] then for clarity purposes it would be "nice" to keep the same numerical value for the range 0 .. N instead of adding textual noise such as a -1 bias.

For example, in C or JavaScript, to iterate over an array of N elements a programmer would write the common idiom of i = 0, i < N with the interval [0,N) instead of the slightly more verbose [0,N-1]:

function main() {_x000D_
    var output = "";_x000D_
    var a = [ 2, 3, 5, 7,  11, 13, 17, 19, 23, 29 ];_x000D_
    for( var i = 0; i < 10; i++ ) // [0,10)_x000D_
       output += "[" + i + "]: " + a[i] + "\n";_x000D_
_x000D_
    if (typeof window === 'undefined') // Node command line_x000D_
        console.log( output )_x000D_
    else_x000D_
        document.getElementById('output1').innerHTML = output;_x000D_
}

 <html>_x000D_
     <body onload="main();">_x000D_
         <pre id="output1"></pre>_x000D_
     </body>_x000D_
 </html>

Mathematicians, since they start counting at 1, would instead use the i = 1, i <= N nomenclature but now we need to correct the array offset in a zero-based language.

e.g.

function main() {_x000D_
    var output = "";_x000D_
    var a = [ 2, 3, 5, 7,  11, 13, 17, 19, 23, 29 ];_x000D_
    for( var i = 1; i <= 10; i++ ) // [1,10]_x000D_
       output += "[" + i + "]: " + a[i-1] + "\n";_x000D_
_x000D_
    if (typeof window === 'undefined') // Node command line_x000D_
        console.log( output )_x000D_
    else_x000D_
        document.getElementById( "output2" ).innerHTML = output;_x000D_
}

<html>_x000D_
    <body onload="main()";>_x000D_
        <pre id="output2"></pre>_x000D_
    </body>_x000D_
</html>

Aside:

In programming languages that are 0-based you might need a kludge of a dummy zero'th element to use a Mathematical 1-based algorithm. e.g. Python Index Start

Floating-Point

Interval notation is also important for floating-point numbers to avoid subtle bugs.

When dealing with floating-point numbers especially in Computer Graphics (color conversion, computational geometry, animation easing/blending, etc.) often times normalized numbers are used. That is, numbers between 0.0 and 1.0.

It is important to know the edge cases if the endpoints are inclusive or exclusive:

• (0,1) = 1e-M .. 0.999...
• (0,1] = 1e-M .. 1.0
• [0,1) = 0.0 .. 0.999...
• [0,1] = 0.0 .. 1.0

Where M is some machine epsilon. This is why you might sometimes see const float EPSILON = 1e-# idiom in C code (such as 1e-6) for a 32-bit floating point number. This SO question Does EPSILON guarantee anything? has some preliminary details. For a more comprehensive answer see FLT_EPSILON and David Goldberg's What Every Computer Scientist Should Know About Floating-Point Arithmetic

Some implementations of a random number generator, random() may produce values in the range 0.0 .. 0.999... instead of the more convenient 0.0 .. 1.0. Proper comments in the code will document this as [0.0,1.0) or [0.0,1.0] so there is no ambiguity as to the usage.

Example:

• You want to generate random() colors. You convert three floating-point values to unsigned 8-bit values to generate a 24-bit pixel with red, green, and blue channels respectively. Depending on the interval output by random() you may end up with near-white (254,254,254) or white (255,255,255).

     +--------+-----+
     |random()|Byte |
     |--------|-----|
     |0.999...| 254 | <-- error introduced
     |1.0     | 255 |
     +--------+-----+

For more details about floating-point precision and robustness with intervals see Christer Ericson's Real-Time Collision Detection, Chapter 11 Numerical Robustness, Section 11.3 Robust Floating-Point Usage.

For concatenating selectors together when nesting, you need to use the parent selector (&):

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

var a = 0;
var d;
var increment;

for(n in array){
    d = a++;        

    if(n % 6 === 0 && n != 0){
        doc.addPage();
        a = 1;
        d = 0;
    }

    increment = d == 0 ? 10 : 50;
    size = (d * increment) <= 0 ? 10 : d * increment;

    doc.text(array[n], 10, size);
}

If you use Kotlin, you can use extension functions as such, for example:

fun <T> LongSparseArray<T>.valuesIterator(): Iterator<T> {
    val nSize = this.size()
    return object : Iterator<T> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next(): T = valueAt(i++)
    }
}

fun <T> LongSparseArray<T>.keysIterator(): Iterator<Long> {
    val nSize = this.size()
    return object : Iterator<Long> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next(): Long = keyAt(i++)
    }
}

fun <T> LongSparseArray<T>.entriesIterator(): Iterator<Pair<Long, T>> {
    val nSize = this.size()
    return object : Iterator<Pair<Long, T>> {
        var i = 0
        override fun hasNext(): Boolean = i < nSize
        override fun next() = Pair(keyAt(i), valueAt(i++))
    }
}

You can also convert to a list, if you wish. Example:

sparseArray.keysIterator().asSequence().toList()

I think it might even be safe to delete items using remove on the LongSparseArray itself (not on the iterator), as it is in ascending order.

EDIT: Seems there is even an easier way, by using collection-ktx (example here) . It's implemented in a very similar way to what I wrote, actally.

Gradle requires this:

implementation 'androidx.core:core-ktx:#'
implementation 'androidx.collection:collection-ktx:#'

Here's the usage for LongSparseArray :

    val sparse= LongSparseArray<String>()
    for (key in sparse.keyIterator()) {
    }
    for (value in sparse.valueIterator()) {
    }
    sparse.forEach { key, value -> 
    }

And for those that use Java, you can use LongSparseArrayKt.keyIterator , LongSparseArrayKt.valueIterator and LongSparseArrayKt.forEach , for example. Same for the other cases.

unfortunately this is not supported in the builtin tools in visual studio. however, you can create your own data provider using mysql connector but still have to integrate it from code

The most effective one liner that

• returns a boolean (as opposed to Orbling's answer)
• Does not return a false positive when searching for thisClass on an element that has class="thisClass-suffix".
• is compatible with every browser down to at least IE6

function hasClass( target, className ) {
    return new RegExp('(\\s|^)' + className + '(\\s|$)').test(target.className);
}

IF NOT EXISTS( SELECT NULL
            FROM INFORMATION_SCHEMA.COLUMNS
           WHERE table_name = 'TableName'
             AND table_schema = 'SchemaName'
             AND column_name = 'ColumnName')  BEGIN

  ALTER TABLE [SchemaName].[TableName] ADD [ColumnName] int(1) NOT NULL default '0';

END;

function showstuff(boxid){
   document.getElementById(boxid).style.visibility="visible";
}

<button onclick="showstuff('id_to_show');" />

This will help you, I think.

I expect xxcopy has an option for that.

Bingo:

2.3   By comparison with the file in destination

    The switches in this group select files based on the
    comparison between the files in the source and those in
    the destination.  They are often used for periodic backup
    and directory synchronization purposes. These switches
    were originally created as variations of directory backup.
    They are also convenient for selecting files for deletion.

2.3.1  by Presence/Absence

    The /BB and /U switches are the two switches which select
    files by the pure presence or absence as the criteria.
    Other switches in the this group (Group 2.3) are also
    affected by the file in the destination, but for a
    particular characteristics for comparison's sake.

    /BB  Selects files that are present in source but not in destination.
    /U   Selects files that are present in both source and destination.

You can use max_element() function to find the position of the max element.

int main()
{
    int num, arr[10];
    int x, y, a, b;

    cin >> num;

    for (int i = 0; i < num; i++)
    {
        cin >> arr[i];
    }

    cout << "Max element Index: " << max_element(arr, arr + num) - arr;

    return 0;
}

For me it was changing.

this.name = response.data;

To what computed returns so;

this.$store.state.name = response.data;

Take a look at iScroll v4 here: http://cubiq.org/iscroll-4

It may not be jQuery, but it works on Desktop Mobile, and iPad quite well; I've used it on many projects and combined it with jQuery.

Good Luck!

I had the same issue working on a project with Maven. Here how I fixed it: I just put the sources (images, musics and other stuffs) in the resources directory:

src/main/resources

I created the same structure for the packages in the resources directory too. For example:

If my class is on

com.package1.main

In the resources directory I put one package with the same name

com.package1.main

So I use

getClass().getResource("resource.png");

Man, I never have done that in HTML 5 but I'll try. Take a look on this fiddle.

I have used some jQuery, HTML5 native events and properties and a custom attribute on input tag(this may cause problem if you try to validade your code). I didn't tested in all browsers but I think it may work.

This is the field validation JavaScript code with jQuery:

$(document).ready(function()
{
    $('input[required], input[required="required"]').each(function(i, e)
    {
        e.oninput = function(el)
        {
            el.target.setCustomValidity("");

            if (el.target.type == "email")
            {
                if (el.target.validity.patternMismatch)
                {
                    el.target.setCustomValidity("E-mail format invalid.");

                    if (el.target.validity.typeMismatch)
                    {
                         el.target.setCustomValidity("An e-mail address must be given.");
                    }
                }
            }
        };

        e.oninvalid = function(el)
        {
            el.target.setCustomValidity(!el.target.validity.valid ? e.attributes.requiredmessage.value : "");
        };
    });
});

Nice. Here is the simple form html:

<form method="post" action="" id="validation">
    <input type="text" id="name" name="name" required="required" requiredmessage="Name is required." />
    <input type="email" id="email" name="email" required="required" requiredmessage="A valid E-mail address is required." pattern="^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9]+$" />

    <input type="submit" value="Send it!" />
</form>

The attribute requiredmessage is the custom attribute I talked about. You can set your message for each required field there cause jQuery will get from it when it will display the error message. You don't have to set each field right on JavaScript, jQuery does it for you. That regex seems to be fine(at least it block your [email protected]! haha)

As you can see on fiddle, I make an extra validation of submit form event(this goes on document.ready too):

$("#validation").on("submit", function(e)
{
    for (var i = 0; i < e.target.length; i++)
    {
        if (!e.target[i].validity.valid)
        {
            window.alert(e.target.attributes.requiredmessage.value);
            e.target.focus();
            return false;
        }
    }
});

I hope this works or helps you in anyway.

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

You need the correct argument for the nth-child pseudo class.

• The argument should be in the form of an + b to match every a^th child starting from b.

• Both a and b are optional integers and both can be zero or negative.

  • If a is zero then there is no "every a^th child" clause.
  • If a is negative then matching is done backwards starting from b.
  • If b is zero or negative then it is possible to write equivalent expression using positive b e.g. 4n+0 is same as 4n+4. Likewise 4n-1 is same as 4n+3.

Examples:

Select every 4th child (4, 8, 12, ...)

li:nth-child(4n) {_x000D_
  background: yellow;_x000D_
}

<ol>_x000D_

Select every 4th child starting from 1 (1, 5, 9, ...)

  <li>Item</li>_x000D_
  <li>Item</li>_x000D_
</ol>

Select every 3rd and 4th child from groups of 4 (3 and 4, 7 and 8, 11 and 12, ...)

/* two selectors are required */_x000D_
li:nth-child(4n+3),_x000D_
li:nth-child(4n+4) {_x000D_

Excerpted from the documentation for Percent Strings at http://ruby-doc.org/core/doc/syntax/literals_rdoc.html#label-Percent+Strings:

Besides %(...) which creates a String, the % may create other types of object. As with strings, an uppercase letter allows interpolation and escaped characters while a lowercase letter disables them.

These are the types of percent strings in ruby:
...
%w: Array of Strings

This is a PDO-only visualization, as the mysql_* library is deprecated.

<?php
    // Begin Vault (this is in a vault, not actually hard-coded)
    $host="hostname";
    $username="GuySmiley";
    $password="thePassword";
    $dbname="dbname";
    $port="3306";
    // End Vault

    try {
        $dbh = new PDO("mysql:host=$host;port=$port;dbname=$dbname;charset=utf8", $username, $password);
        $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        echo "I am connected.<br/>";

        // ... continue with your code

        // PDO closes connection at end of script
    } catch (PDOException $e) {
        echo 'PDO Exception: ' . $e->getMessage();
        exit();
    }
?>

Note that this OP Question appeared not to be about port numbers afterall. If you are using the default port of 3306 always, then consider removing it from the uri, that is, remove the port=$port; part.

If you often change ports, consider the above port usage for more maintainability having changes made to the $port variable.

Some likely errors returned from above:

PDO Exception: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
PDO Exception: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known.

In the below error, we are at least getting closer, after changing our connect information:

PDO Exception: SQLSTATE[HY000] [1045] Access denied for user 'GuySmiley'@'localhost' (using password: YES)

After further changes, we are really close now, but not quite:

PDO Exception: SQLSTATE[HY000] [1049] Unknown database 'mustard'

From the Manual on PDO Connections:

Does not work for multidimensional arrays, because references are used here.

import numpy as np

# swaps
data = np.random.random(2)
print(data)
data[0], data[1] = data[1], data[0]
print(data)

# does not swap
data = np.random.random((2, 2))
print(data)
data[0], data[1] = data[1], data[0]
print(data)

I've recently started using http://schemaspy.sourceforge.net/ . It uses GraphViz, and it strikes me as having a good balance between usability and simplicity.

Try this :

<style type="text/css">
        .myTableStyle
        {
           position:absolute;
           top:50%;
           left:50%; 

            /*Alternatively you could use: */
           /*
              position: fixed;
               bottom: 50%;
               right: 50%;
           */


        }
    </style>

false == 0 and true = !false

i.e. anything that is not zero and can be converted to a boolean is not false, thus it must be true.

Some examples to clarify:

if(0)          // false
if(1)          // true
if(2)          // true
if(0 == false) // true
if(0 == true)  // false
if(1 == false) // false
if(1 == true)  // true
if(2 == false) // false
if(2 == true)  // false
cout << false  // 0
cout << true   // 1

true evaluates to 1, but any int that is not false (i.e. 0) evaluates to true but is not equal to true since it isn't equal to 1.

What I like to do is the following (but make sure to read to the end to use the proper type of constants):

internal static class ColumnKeys
{
    internal const string Date = "Date";
    internal const string Value = "Value";
    ...
}

Read this to know why const might not be what you want. Possible type of constants are:

• const fields. Do not use across assemblies (public or protected) if value might change in future because the value will be hardcoded at compile-time in those other assemblies. If you change the value, the old value will be used by the other assemblies until they are re-compiled.
• static readonly fields
• static property without set

The length function will do it. See http://www.techonthenet.com/oracle/functions/length.php

        PagedDataSource objPage = new PagedDataSource();

        DataView dataView = listData.DefaultView;
        objPage.AllowPaging = true;
        objPage.DataSource = dataView;
        objPage.PageSize = PageSize;

        TotalPages = objPage.PageCount;

        objPage.CurrentPageIndex = CurrentPage - 1;

        //Convert PagedDataSource to DataTable
        System.Collections.IEnumerator pagedData = objPage.GetEnumerator();

        DataTable filteredData = new DataTable();
        bool flagToCopyDTStruct = false;
        while (pagedData.MoveNext())
        {
            DataRowView rowView = (DataRowView)pagedData.Current;
            if (!flagToCopyDTStruct)
            {
                filteredData = rowView.Row.Table.Clone();
                flagToCopyDTStruct = true;
            }
            filteredData.LoadDataRow(rowView.Row.ItemArray, true);
        }

        //Here is your filtered DataTable
        return filterData; 

I'm late to the party, but for Mac users who don't want to go down the XQuartz path, here is a working example that builds a Fedora Image, with a Desktop Environment (xfce) using Xvfb and VNC. It's simple, and works:

• https://github.com/ddual/docker_recipes#fedora-with-an-x-window-system
• https://github.com/ddual/docker_recipes/tree/master/fedora_gui

On a Mac, you can just access it using the Screen Sharing (default) application, connecting to localhost:5901.

If you wish to get JSON object without any extra fields - please add this annotation to your class, it worked perfect for me.

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})

You can also add in your application.properties file this row, but it will add an extra field to your JSON.

spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false

Consider:

int[] myArray = new int[10];
String myString = "hello world!";
List<int> myList = new ArrayList<int>();

myArray.length    // Gives the length of the array
myString.length() // Gives the length of the string
myList.size()     // Gives the length of the list

It's very likely that strings and arrays were designed at different times and hence ended up using different conventions. One justification is that since Strings use arrays internally, a method, length(), was used to avoid duplication of the same information. Another is that using a method length() helps emphasize the immutability of strings, even though the size of an array is also unchangeable.

Ultimately this is just an inconsistency that evolved that would definitely be fixed if the language were ever redesigned from the ground up. As far as I know no other languages (C#, Python, Scala, etc.) do the same thing, so this is likely just a slight flaw that ended up as part of the language.

You'll get an error if you use the wrong one anyway.

Adding to the accepted answer, you can used DATABASE_DEFAULT as encoding.

This allows database to make choice for you and your code becomes more portable.

SELECT MyColumn
FROM 
    FirstTable a
        INNER JOIN SecondTable b
            ON a.MyID COLLATE DATABASE_DEFAULT = b.YourID COLLATE DATABASE_DEFAULT

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

The simpler way:

h = ''
i = None
j = 0
k = 1
print h or i or j or k

Will print 1

print k or j or i or h

Will print 1

Here's a handy helper to prevent making the annoying GCD call over and over again:

public func delay(bySeconds seconds: Double, dispatchLevel: DispatchLevel = .main, closure: @escaping () -> Void) {
    let dispatchTime = DispatchTime.now() + seconds
    dispatchLevel.dispatchQueue.asyncAfter(deadline: dispatchTime, execute: closure)
}

public enum DispatchLevel {
    case main, userInteractive, userInitiated, utility, background
    var dispatchQueue: DispatchQueue {
        switch self {
        case .main:                 return DispatchQueue.main
        case .userInteractive:      return DispatchQueue.global(qos: .userInteractive)
        case .userInitiated:        return DispatchQueue.global(qos: .userInitiated)
        case .utility:              return DispatchQueue.global(qos: .utility)
        case .background:           return DispatchQueue.global(qos: .background)
        }
    }
}

Now you simply delay your code on the Main thread like this:

delay(bySeconds: 1.5) { 
    // delayed code
}

If you want to delay your code to different thread:

delay(bySeconds: 1.5, dispatchLevel: .background) { 
    // delayed code that will run on background thread
}

If you prefer a Framework that also has some more handy features then checkout HandySwift. You can add it to your project via Carthage then use it exactly like in the examples above:

import HandySwift    

delay(bySeconds: 1.5) { 
    // delayed code
}

You should use:

dbcc shrinkdatabase (MyDB)

It will shrink the log file (keep a windows explorer open and see it happening).

There are several to pick from in the gallery but the one I'm using, which offers considerable level of configurability still remaining unobtrusive to the rest of the settings is Beautify by Michele Melluso. It works on both CSS and SCSS and lets you indent 3 spaces keeping the rest of the code at 2 spaces, which is nice.

You can snatch it from GitHub and adapt it yourself, should you feel like it too.

Below snippet is sufficient to understand how I encountered the same issue but in a different scenario and how I solved it using the guidance in the accepted answer. In my case I was trying to log the keys of object present in the 0th index of the 'defaultViewData' array using Object.keys() method.

defaultViewData = [{"name": "DEFAULT_VIEW_PLP","value": {"MSH25": "LIST"}}] 

console.log('DEFAULT_VIEW', Object.keys(this.props.defaultViewData[0]));

The console.log was not getting printed and I was getting the same error as posted in this question. To prevent that error I added below condition

    if(this.props.defaultViewData[0]) {
  console.log('DEFAULT_VIEW', Object.keys(this.props.defaultViewData[0]));
}

Adding this check ensured that I didn't get this error. I hope this helps for someone.

Note: This is React.js code. (although to understand the problem it doesn't matter).

Thanks to Mike's comment, I've re-read the doc and I've realised that my current user (i.e. userA that already has the create privilege) wasn't a direct/indirect member of the new owning role...

So the solution was quite simple - I've just done this grant:

grant userB to userA;

That's all folks ;-)

Another requirement is that the object has to be owned by user userA before altering it...

According to Extensible Messaging and Presence Protocol (Wikipedia), the standard TCP port for the server is 5222.

The client would presumably use the same ports as the messaging protocol, but can also use http (port 80) and https (port 443) for message delivery. These have the advantage of working for users behind firewalls, so your network admin should not need to get involved.

If you have to choose between __repr__ or __str__ go for the first one, as by default implementation __str__ calls __repr__ when it wasn't defined.

Custom Vector3 example:

class Vector3(object):
    def __init__(self, args):
        self.x = args[0]
        self.y = args[1]
        self.z = args[2]

    def __repr__(self):
        return "Vector3([{0},{1},{2}])".format(self.x, self.y, self.z)

    def __str__(self):
        return "x: {0}, y: {1}, z: {2}".format(self.x, self.y, self.z)

In this example, repr returns again a string that can be directly consumed/executed, whereas str is more useful as a debug output.

v = Vector3([1,2,3])
print repr(v)    #Vector3([1,2,3])
print str(v)     #x:1, y:2, z:3

yes there is!

$(function () {
    $("#first").animate({
       width: '200px'
    }, { duration: 200, queue: false });

    $("#second").animate({
       width: '600px'
    }, { duration: 200, queue: false });
});

O.K. I neither have rep to comment on previous answer (of Philippe De Muyter) nor raise it's score, hence a new example using his define for SIGNED_MAX trivially extended for unsigned types:

// We can use it to define limits based on actual compiler built-in types also: 
#define INT_MAX   SIGNED_MAX(int)
// based on the above, we can extend it for unsigned types also:
#define UNSIGNED_MAX(x) (  (SIGNED_MAX(x)<<1) | 1 ) // We reuse SIGNED_MAX
#define UINT_MAX  UNSIGNED_MAX(unsigned int) // on ARM: 4294967295
// then we can have:
unsigned int width = UINT_MAX;

Unlike using this or that header, here we use the real type from the compiler.

This solution work for me... just type export PATH=$JAVA_HOME/jre/bin:$PATH in the terminal then run mvn -version it will show the same error but with a log like this

which: no javac in (/jre/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/puppetlabs/bin)
Warning: JAVA_HOME environment variable is not set.
Apache Maven 3.2.5 (12a6b3acb947671f09b81f49094c53f426d8cea1; 2014-12-14T22:59:23+05:30)

now copy the Java home path i.e. /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64/jre in my case.

now type,

and the error gets resolve. NOTE: paste your own path which is shown by your machine in mvn log at export JAVA_HOME.

Another issue is that you're reading with scanf("%f", &input); only. If the user types something that can't be interpreted as a C floating-point number, like "pi", the scanf() call will not assign anything to input, and won't progress from there. This means it would attempt to keep reading "pi", and failing.

Given the change to while(!feof(stdin)) which other posters are correctly recommending, if you typed "pi" in there would be an endless loop of printing out the former value of input and printing the prompt, but the program would never process any new input.

scanf() returns the number of assignments to input variables it made. If it made no assignment, that means it didn't find a floating-point number, and you should read through more input with something like char string[100];scanf("%99s", string);. This will remove the next string from the input stream (up to 99 characters, anyway - the extra char is for the null terminator on the string).

You know, this is reminding me of all the reasons I hate scanf(), and why I use fgets() instead and then maybe parse it using sscanf().

No recursion or nested loops. A few lines. Well formatted and easy to read:

def flatten_deep(arr: list):
""" Flattens arbitrarily-nested list `arr` into single-dimensional. """

while arr:
    if isinstance(arr[0], list):  # Checks whether first element is a list
        arr = arr[0] + arr[1:]  # If so, flattens that first element one level
    else:
        yield arr.pop(0)  # Otherwise yield as part of the flat array

flatten_deep(L)

From my own code at https://github.com/jorgeorpinel/flatten_nested_lists/blob/master/flatten.py

open command prompt and run the following commands (assuming python 2.7):

cd c:\Python27\scripts\
pip install opencv-python

the above works for me for python 2.7 on windows 10 64 bit

You shouldn't use flag e (or eval in general).

You can also use T-Regx library

pattern('(^|_)([a-z])')->replace($word)->by()->group(2)->callback('strtoupper');

Hi This is my solution

Javascript code

var base64before = document.querySelector('img').src;
var base64 = base64before.replace(/^data:image\/(png|jpg);base64,/, "");
var httpPost = new XMLHttpRequest();
var path = "your url";
var data = JSON.stringify(base64);

httpPost.open("POST", path, false);
// Set the content type of the request to json since that's what's being sent
httpPost.setRequestHeader('Content-Type', 'application/json');
httpPost.send(data);

This is my Java code.

public void saveImage(InputStream imageStream){
InputStream inStream = imageStream;

try {
    String dataString = convertStreamToString(inStream);

    byte[] imageBytes = javax.xml.bind.DatatypeConverter.parseBase64Binary(dataString);
    BufferedImage image = ImageIO.read(new ByteArrayInputStream(imageBytes));
    // write the image to a file
    File outputfile = new File("/Users/paul/Desktop/testkey/myImage.png");
    ImageIO.write(image, "png", outputfile);

    }catch(Exception e) {
        System.out.println(e.getStackTrace());
    }
}


static String convertStreamToString(java.io.InputStream is) {
    java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A");
    return s.hasNext() ? s.next() : "";
}

Another thing to consider is that, since there is no multiple inheritance, if you want a class to be able to implement/inherit from your interface/abstract class, but inherit from another base class, use an interface.

For fullscreen of browser rendering area there is a simple solution supported by all modern browsers.

div#placeholder {
    height: 100vh;
}

The only notable exception is the Android below 4.3 - but ofc only in the system browser/webview element (Chrome works ok).

Browser support chart: http://caniuse.com/viewport-units

For fullscreen of monitor please use HTML5 Fullscreen API

The following works:

sudo apt-get --purge remove mysql-client mysql-server mysql-common
sudo apt-get autoremove

The full list is:

DB, DW, DD, DQ, DT, DDQ, and DO (used to declare initialized data in the output file.)

See: http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html

They can be invoked in a wide range of ways: (Note: for Visual-Studio - use "h" instead of "0x" syntax - eg: not 0x55 but 55h instead):

    db      0x55                ; just the byte 0x55
    db      0x55,0x56,0x57      ; three bytes in succession
    db      'a',0x55            ; character constants are OK
    db      'hello',13,10,'$'   ; so are string constants
    dw      0x1234              ; 0x34 0x12
    dw      'A'                 ; 0x41 0x00 (it's just a number)
    dw      'AB'                ; 0x41 0x42 (character constant)
    dw      'ABC'               ; 0x41 0x42 0x43 0x00 (string)
    dd      0x12345678          ; 0x78 0x56 0x34 0x12
    dq      0x1122334455667788  ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    ddq     0x112233445566778899aabbccddeeff00
    ; 0x00 0xff 0xee 0xdd 0xcc 0xbb 0xaa 0x99
    ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    do      0x112233445566778899aabbccddeeff00 ; same as previous
    dd      1.234567e20         ; floating-point constant
    dq      1.234567e20         ; double-precision float
    dt      1.234567e20         ; extended-precision float

DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.

Here is code that I used to prevent CSRF token problem when sending POST request with ajax

$(document).ready(function(){
    function getCookie(c_name) {
        if(document.cookie.length > 0) {
            c_start = document.cookie.indexOf(c_name + "=");
            if(c_start != -1) {
                c_start = c_start + c_name.length + 1;
                c_end = document.cookie.indexOf(";", c_start);
                if(c_end == -1) c_end = document.cookie.length;
                return unescape(document.cookie.substring(c_start,c_end));
            }
        }
        return "";
    }

    $(function () {
        $.ajaxSetup({
            headers: {
                "X-CSRFToken": getCookie("csrftoken")
            }
        });
    });

});

Try replacing <%# Eval("item") %> with <%# If(Eval("item"), "0 value") %> (or <%# Eval("item") ?? "0 value" %>, when using C#).

To answer the question of going from an existing python datetime to a pandas Timestamp do the following:

    import time, calendar, pandas as pd
    from datetime import datetime
    
    def to_posix_ts(d: datetime, utc:bool=True) -> float:
        tt=d.timetuple()
        return (calendar.timegm(tt) if utc else time.mktime(tt)) + round(d.microsecond/1000000, 0)
    
    def pd_timestamp_from_datetime(d: datetime) -> pd.Timestamp:
        return pd.to_datetime(to_posix_ts(d), unit='s')
    
    dt = pd_timestamp_from_datetime(datetime.now())
    print('({}) {}'.format(type(dt), dt))

Output:

(<class 'pandas._libs.tslibs.timestamps.Timestamp'>) 2020-09-05 23:38:55

I was hoping for a more elegant way to do this but the to_posix_ts is already in my standard tool chain so I'm moving on.

I think this is the simplest way:

Foo[] array = list.toArray(new Foo[0]);

The fact that std::map insert() function doesn't overwrite value associated with the key allows us to write object enumeration code like this:

string word;
map<string, size_t> dict;
while(getline(cin, word)) {
    dict.insert(make_pair(word, dict.size()));
}

It's a pretty common problem when we need to map different non-unique objects to some id's in range 0..N. Those id's can be later used, for example, in graph algorithms. Alternative with operator[] would look less readable in my opinion:

string word;
map<string, size_t> dict;
while(getline(cin, word)) {
    size_t sz = dict.size();
    if (!dict.count(word))
        dict[word] = sz; 
} 

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

You should look at the logs. I just ran into the same error and realized from the logs it was because I had a yarn.lock and package-lock.json

s/\([^)]*\)//

So in Python, you'd do:

re.sub(r'\([^)]*\)', '', filename)

Use QString::arg() for the same effect.

You can use sort() function. sort() exists in algorithm header file

        #include<bits/stdc++.h>
        using namespace std;


        int main()
        {
            ios::sync_with_stdio(false);
            string str = "sharlock";

            sort(str.begin(), str.end());
            cout<<str<<endl;

            return 0;
        }

Output:

achklors

You need a regular expression like "\\s+", which means: split whenever at least one whitespace is encountered. The full Java code is:

try {
    String[] splitArray = input.split("\\s+");
} catch (PatternSyntaxException ex) {
    // 
}

The normal usage of static is to access the function directly with out any object creation. Same as in java main we could not create any object for that class to invoke the main method. It will execute automatically. If we want to execute manually we can call by using main() inside the class and ClassName.main from outside the class.

To go one step further, I assume you want to do something with these dtypes. df.dtypes.to_dict() comes in handy.

my_type = 'float64' #<---

dtypes = dataframe.dtypes.to_dict()

for col_nam, typ in dtypes.items():
    if (typ != my_type): #<---
        raise ValueError(f"Yikes - `dataframe['{col_name}'].dtype == {typ}` not {my_type}")

You'll find that Pandas did a really good job comparing NumPy classes and user-provided strings. For example: even things like 'double' == dataframe['col_name'].dtype will succeed when .dtype==np.float64.

Also, you can use the "sql" parameter as a format specifier:

context.Database.SqlQuery<MyEntityType>("mySpName @param1 = {0}", param1)

No you can't use bind variables that way. In your second example :into_bind in v_query_str is just a placeholder for value of variable v_num_of_employees. Your select into statement will turn into something like:

SELECT COUNT(*) INTO  FROM emp_...

because the value of v_num_of_employees is null at EXECUTE IMMEDIATE.

Your first example presents the correct way to bind the return value to a variable.

Edit

The original poster has edited the second code block that I'm referring in my answer to use OUT parameter mode for v_num_of_employees instead of the default IN mode. This modification makes the both examples functionally equivalent.

That should be considered a very bad programming practice to call PHP code from a database trigger. If you will explain the task you are trying to solve using such "mad" tricks, we might provide a satisfying solution.

ADDED 19.03.2014:

I should have added some reasoning earlier, but only found time to do this now. Thanks to @cmc for an important remark. So, PHP triggers add the following complexities to your application:

• Adds a certain degree of security problems to the application (external PHP script calls, permission setup, probably SELinux setup etc) as @Johan says.

• Adds additional level of complexity to your application (to understand how database works you now need to know both SQL and PHP, not only SQL) and you will have to debug PHP also, not only SQL.

• Adds additional point of failure to your application (PHP misconfiguration for example), which needs to be diagnosied also ( I think trigger needs to hold some debug code which will log somwewhere all insuccessful PHP interpreter calls and their reasons).

• Adds additional point of performance analysis. Each PHP call is expensive, since you need to start interpreter, compile script to bytecode, execute it etc. So each query involving this trigger will execute slower. And sometimes it will be difficult to isolate query performance problems since EXPLAIN doesn't tell you anything about query being slower because of trigger routine performance. And I'm not sure how trigger time is dumped into slow query log.

• Adds some problems to application testing. SQL can be tested pretty easily. But to test SQL + PHP triggers, you will have to apply some skill.

I have found the solution in spring boot by using @CrossOrigin annotation.

@RestController
@CrossOrigin
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

you can use

find .

to search all files/dirs in the current directory recurive

Than you can pipe the output the xargs command like so

find . | xargs 'command here'

Since not all of my clients use authenticated SMTP accounts, I resorted to using the SMTP account only if app key values are supplied in web.config file.

Here is the VB code:

sSMTPUser = ConfigurationManager.AppSettings("SMTPUser")
sSMTPPassword = ConfigurationManager.AppSettings("SMTPPassword")

If sSMTPUser.Trim.Length > 0 AndAlso sSMTPPassword.Trim.Length > 0 Then
    NetClient.Credentials = New System.Net.NetworkCredential(sSMTPUser, sSMTPPassword)

    sUsingCredentialMesg = "(Using Authenticated Account) " 'used for logging purposes
End If

NetClient.Send(Message)

Another solution without you having to manually mess around with the Unicode characters can be found in Making Font Awesome awesome - Using icons without i-tags (disclaimer: I wrote this article).

In a nutshell, you can create a new class like this:

.icon::before {
    display: inline-block;
    margin-right: .5em;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    transform: translate(0, 0);
}

And then use it with any icon, for example:

<a class="icon fa-car" href="#">This is a link</a>

Keep in mind that you have to exactly specify your path to your language.JSON like this:

language: {
    url: '/mywebsite/js/localisation/German.json'
}

I was wondering the same thing so i googled and ended up here. I did a small test in python (extremely simple) just to see and this is what I got:

For:

def for_func(n = 0):
    for n in range(500):
        n = n + 1

python -m timeit "import for_func; for_func.for_func()" > for_func.txt

10000 loops, best of 3: 40.5 usec per loop

While:

def while_func(n = 0):
    while n < 500:
        n = n + 1

python -m timeit "import while_func; while_func.while_func()" > while_func.txt

10000 loops, best of 3: 45 usec per loop

NPP+ v7.9.1 with the latest version of XMLTools can't format exported VBA code from Office 2016/2019 Word. It puts all the code on the same line since it strips the CRLF out. Moreover, when you enable "auto validation" it errors out on the first VBA line that is, Attribute VB_Name = "The VBA module name". So any of the xml tool validations apparently can't be used for VBA validation.

MyString.Remove(1, 2); also works

I consider the structure as for (if) A else B, and for(if)-else is a special if-else, roughly. It may help to understand else.

A and B is executed at most once, which is the same as if-else structure.

for(if) can be considered as a special if, which does a loop to try to meet the if condition. Once the if condition is met, A and break; Else, B.

I've just attempted this - I needed to test some development code on my localhost Apache on Windows. This was WAAAY more difficult than it should be. But here are the steps that managed to work after much hairpulling...

I found that my Apache install comes with openssl.exe which is helpful. If you don't have a copy, you'll need to download it. My copy was in Apache2\bin folder which is how I reference it below.

Steps:

1. Ensure you have write permissions to your Apache conf folder
2. Open a command prompt in Apache2\conf folder
3. Type
   ..\bin\openssl req -config openssl.cnf -new -out blarg.csr -keyout blarg.pem

4. You can leave all questions blank except:

   • PEM Passphrase: a temporary password such as "password"
   • Common Name: the hostname of your server

   

5. When that completes, type
   ..\bin\openssl rsa -in blarg.pem -out blarg.key

6. Generate your self-signed certificate by typing:
   ..\bin\openssl x509 -in blarg.csr -out blarg.cert -req -signkey blarg.key -days 365

   

7. Open Apache's conf\httpd.conf file and ensure SSL module is enabled - there should be no hash at the start of this line:
   LoadModule ssl_module modules/mod_ssl.so

   

8. Some Apache installations place the SSL config in a separate file. If so, ensure that the SSL conf file is being included. In my case I had to uncomment this line:
   Include conf/extra/httpd-ssl.conf

9. In the SSL config httpd-ssl.conf I had to update the following lines:

   • Update
     SSLSessionCache "shmcb:C:\Program Files (x86)\Zend\Apache2/logs/ssl_scache(512000)"
     to
     SSLSessionCache "shmcb:C:/Progra\~2/Zend/Apache2/logs/ssl_scache(512000)"
     (The brackets in the path confuse the module, so we need to escape them)
   • DocumentRoot - set this to the folder for your web files
   • ServerName - the server's hostname
   • SSLCertificateFile "conf/blarg.cert"
   • SSLCertificateKeyFile "conf/blarg.key"

   

10. Restart Apache.

11. Try loading https://localhost/ in your browser.

Hopefully you made it this far. Feel free to update this post with any other helpful info.

Javascript now has a specific built in object called Map, you can call as follows :

   var myMap = new Map()

You can update it with .set :

   myMap.set("key0","value")

This has the advantage of methods you can use to handle look ups, like the boolean .has

  myMap.has("key1"); // evaluates to false 

You can use this before calling .get on your Map object to handle looking up non-existent keys

I had a similar issue and this is what worked for me.

Add the NodeSource package signing key:

curl -sSL https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
# wget can also be used:
# wget --quiet -O - https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -

Add the desired NodeSource repository:

# Replace with the branch of Node.js or io.js you want to install: node_6.x, node_12.x, etc...
VERSION=node_12.x
# The below command will set this correctly, but if lsb_release isn't available, you can set it manually:
# - For Debian distributions: jessie, sid, etc...
# - For Ubuntu distributions: xenial, bionic, etc...
# - For Debian or Ubuntu derived distributions your best option is to use the codename corresponding to the upstream release your distribution is based off. This is an advanced scenario and unsupported if your distribution is not listed as supported per earlier in this README.

To show result till yesterday

WHERE DATE(date_time) < CURDATE()

To show results of 10 days

WHERE date_time < NOW() - INTERVAL 10 DAY

To show results before 10 days

WHERE DATE(date_time) < DATE(NOW() - INTERVAL 10 DAY)

These will work for you

You can find dates like this

SELECT DATE(NOW() - INTERVAL 11 DAY)

This is really old issue, but I just had similar problem. I was doing something like this :

// entity
$entityOne = $this->em->find(Parent::class, 1);

// do something on other entites (SomeEntityClass)
$this->em->persist($entity);
$this->em->flush();
$this->em->clear();

// and at end I was trying to save changes to first one by
$this->em->persist($entityOne);
$this->em->flush();
$this->em->clear();

Problem was that clear detach all entities including the first one and throw error The EntityManager is closed.

In my case solution was to just do clear on distinct type of Entity and leave $entityOne still under EM:

$this->em->clear(SomeEntityClass::class);

Case sensitive: document.getElementById (notice the capital B).

If you want to hide overflow on fixed-position elements, the simplest approach I've found is to place the element inside a container element, and apply position:fixed and overflow:hidden to that element instead of the contained element (you must remove position:fixed from the contained element for this to work). The content of the fixed container should then be clipped as expected.

In my case I was having trouble with using object-fit:cover on a fixed-position element (it was spilling outside the bounds of the page body, regardless of overflow:hidden). Placing it inside a fixed container with overflow:hidden on the container fixed the issue.

If you’re using the Spring Framework then you can use the Spring Expression Language (SpEL) for that. I’ve wrote a small library that provides JSR-303 validator based on SpEL – it makes cross-field validations a breeze! Take a look at https://github.com/jirutka/validator-spring.

This will validate length and equality of the password fields.

@SpELAssert(value = "pass.equals(passVerify)",
            message = "{validator.passwords_not_same}")
public class MyBean {

    @Size(min = 6, max = 50)
    private String pass;

    private String passVerify;
}

You can also easily modify this to validate the password fields only when not both empty.

@SpELAssert(value = "pass.equals(passVerify)",
            applyIf = "pass || passVerify",
            message = "{validator.passwords_not_same}")
public class MyBean {

    @Size(min = 6, max = 50)
    private String pass;

If you have directory listing disabled in your webserver, then the only way somebody will find it is by guessing or by finding a link to it.

That said, I've seen hacking scripts attempt to "guess" a whole bunch of these common names. "secret.html" would probably be in such a guess list.

The more reasonable solution is to restrict access using a username/password via a htaccess file (for apache) or the equivalent setting for whatever webserver you're using.

When the user exits the FE attempt to rename the backend MDB preferably with todays date in the name in yyyy-mm-dd format. Ensure you close all bound forms, including hidden forms, and reports before doing this. If you get an error message, oops, its busy so don't bother. If it is successful then compact it back.

See my Backup, do you trust the users or sysadmins? tips page for more info.

Warning about using TODAY (or any calcs in a column).

If you set up a filter and have JUST [Today] it it you should be fine.

But the moment you do something like [Today]-1 ... the view will no longer show up when trying to pick it for alerts.

Another microsoft wonder.

The link to a function in a dynamic library is resolved when the library is loaded or at run time. Therefore, both the executable file and dynamic library are loaded into memory when the program is run. The memory address at which a dynamic library is loaded cannot be determined in advance, because a fixed address might clash with another dynamic library requiring the same address.

There are two commonly used methods for dealing with this problem:

1.Relocation. All pointers and addresses in the code are modified, if necessary, to fit the actual load address. Relocation is done by the linker and the loader.

2.Position-independent code. All addresses in the code are relative to the current position. Shared objects in Unix-like systems use position-independent code by default. This is less efficient than relocation if program run for a long time, especially in 32-bit mode.

The name "position-independent code" actually implies following:

• The code section contains no absolute addresses that need relocation, but only self relative addresses. Therefore, the code section can be loaded at an arbitrary memory address and shared between multiple processes.

• The data section is not shared between multiple processes because it often contains writeable data. Therefore, the data section may contain pointers or addresses that need relocation.

• All public functions and public data can be overridden in Linux. If a function in the main executable has the same name as a function in a shared object, then the version in main will take precedence, not only when called from main, but also when called from the shared object. Likewise, when a global variable in main has the same name as a global variable in the shared object, then the instance in main will be used, even when accessed from the shared object.

This so-called symbol interposition is intended to mimic the behavior of static libraries.

A shared object has a table of pointers to its functions, called procedure linkage table (PLT) and a table of pointers to its variables called global offset table (GOT) in order to implement this "override" feature. All accesses to functions and public variables go through this tables.

p.s. Where dynamic linking cannot be avoided, there are various ways to avoid the timeconsuming features of the position-independent code.

The problem raised from using non-typed DBContext or DBSet if you using Interface and implement method of savechanges in a generic way

If this is your case I propose to strongly typed DBContex for example

MyDBContext.MyEntity.Add(mynewObject)

then .Savechanges will work

May 2020 Here's a simple solution i found and it will resolve for all of my projects ,on windows if your project is somewhere inside c: directory , create new file .jshintrc and save it in C directory open this .jshintrc file and write { "esversion": 6} and that's it. the warnings should go away , same will work in d directory

yes you can also enable this setting for the specific project only by same creating a .jshintrc file in your project's root and adding { "esversion": 6}

Getting SOAP working usually does not require compiling PHP from source. I would recommend trying that only as a last option.

For good measure, check to see what your phpinfo says, if anything, about SOAP extensions:

$ php -i | grep -i soap

to ensure that it is the PHP extension that is missing.

Assuming you do not see anything about SOAP in the phpinfo, see what PHP SOAP packages might be available to you.

In Ubuntu/Debian you can search with:

$ apt-cache search php | grep -i soap

or in RHEL/Fedora you can search with:

$ yum search php | grep -i soap

There are usually two PHP SOAP packages available to you, usually php-soap and php-nusoap. php-soap is typically what you get with configuring PHP with --enable-soap.

In Ubuntu/Debian you can install with:

$ sudo apt-get install php-soap

Or in RHEL/Fedora you can install with:

$ sudo yum install php-soap

After the installation, you might need to place an ini file and restart Apache.

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

You want the (standard) POSIXt type from base R that can be had in 'compact form' as a POSIXct (which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt (which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)

Quick example:

R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10  # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
 POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))
$sec
[1] 11.79

$min
[1] 39

$hour
[1] 18

$mday
[1] 25

$mon
[1] 11

$year
[1] 109

$wday
[1] 5

$yday
[1] 358

$isdst
[1] 0

attr(,"tzone")
[1] "America/Chicago" "CST"             "CDT"

As for reading them in, see help(strptime)

As for difference, easy too:

R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")
Time difference of 51.25 weeks
R> 

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.

if anyone has a problem on Mac, can try this

sudo pip install --upgrade matplotlib --ignore-installed six

you need nested foreach loops

foreach($samplearr as $key => $item){
   echo $key;
    foreach($item as $detail){
       echo $detail['value1'] . " " . $detail['value2']
     }
 }

For me, this code looks more explicit:

CAST(@SomeDate AS datetime) + CAST(@SomeTime AS datetime)

A BehaviorSubject holds one value. When it is subscribed it emits the value immediately. A Subject doesn't hold a value.

Subject example (with RxJS 5 API):

const subject = new Rx.Subject();
subject.next(1);
subject.subscribe(x => console.log(x));

Console output will be empty

BehaviorSubject example:

const subject = new Rx.BehaviorSubject(0);
subject.next(1);
subject.subscribe(x => console.log(x));

Console output: 1

In addition:

• BehaviorSubject should be created with an initial value: new Rx.BehaviorSubject(1)
• Consider ReplaySubject if you want the subject to hold more than one value

You can save your array as a json.
there is documentation for json data type: https://dev.mysql.com/doc/refman/5.7/en/json.html
I think this is the best solution, and will help you maintain your code more readable by avoiding crazy functions.
I expect this is helpful for you.

Following is working for me on dotnet 1.0.1:

./ourView.cshtml

@Html.Partial(
  "_ourPartial.cshtml",
  new ViewDataDictionary(this.Vi??ewData) {
    {
      "hi", "hello" 
    } 
  }
);

./_ourPartial.cshtml

<h1>@this.ViewData["hi"]</h1>

I know I am late to the party, but hopefully this will be useful for someone else. If you are using backbone v0.9.9+, you could use, listenTo and stopListening

initialize: function () {
    this.listenTo(this.model, 'change', this.render);
    this.listenTo(this.model, 'destroy', this.remove);
}

stopListening is called automatically by remove. You can read more here and here
