Programs & Examples On #Remoting

Running the command prompt or Powershell ISE as an administrator fixed this for me.

The error message is giving you most of what you need. This isn't just about the TrustedHosts list; it's saying that in order to use an IP address with the default authentication scheme, you have to ALSO be using HTTPS (which isn't configured by default) and provide explicit credentials. I can tell you're at least not using SSL, because you didn't use the -UseSSL switch.

Note that SSL/HTTPS is not configured by default - that's an extra step you'll have to take. You can't just add -UseSSL.

The default authentication mechanism is Kerberos, and it wants to see real host names as they appear in AD. Not IP addresses, not DNS CNAME nicknames. Some folks will enable Basic authentication, which is less picky - but you should also set up HTTPS since you'd otherwise pass credentials in cleartext. Enable-PSRemoting only sets up HTTP.

Adding names to your hosts file won't work. This isn't an issue of name resolution; it's about how the mutual authentication between computers is carried out.

Additionally, if the two computers involved in this connection aren't in the same AD domain, the default authentication mechanism won't work. Read "help about_remote_troubleshooting" for information on configuring non-domain and cross-domain authentication.

From the docs at http://technet.microsoft.com/en-us/library/dd347642.aspx

HOW TO USE AN IP ADDRESS IN A REMOTE COMMAND
-----------------------------------------------------
    ERROR:  The WinRM client cannot process the request. If the
    authentication scheme is different from Kerberos, or if the client
    computer is not joined to a domain, then HTTPS transport must be used
    or the destination machine must be added to the TrustedHosts
    configuration setting.

The ComputerName parameters of the New-PSSession, Enter-PSSession and
Invoke-Command cmdlets accept an IP address as a valid value. However,
because Kerberos authentication does not support IP addresses, NTLM
authentication is used by default whenever you specify an IP address. 

When using NTLM authentication, the following procedure is required
for remoting.

1. Configure the computer for HTTPS transport or add the IP addresses
   of the remote computers to the TrustedHosts list on the local
   computer.

   For instructions, see "How to Add a Computer to the TrustedHosts
   List" below.


2. Use the Credential parameter in all remote commands.

   This is required even when you are submitting the credentials
   of the current user.

Add few points on top of apesa's excellent post:

1) You can use command below to check the ip address mysql server is listening

netstat -nlt | grep 3306

sample result:

tcp 0  0  xxx.xxx.xxx.xxx:3306  0.0.0.0:*   LISTEN

2) Use FLUSH PRIVILEGES to force grant tables to be loaded if for some reason the changes not take effective immediately

GRANT ALL ON *.* TO 'user'@'localhost' IDENTIFIED BY 'passwd' WITH GRANT OPTION;
GRANT ALL ON *.* TO 'user'@'%' IDENTIFIED BY 'passwd' WITH GRANT OPTION;
FLUSH PRIVILEGES; 
EXIT;

user == the user u use to connect to mysql ex.root
passwd == the password u use to connect to mysql with

3) If netfilter firewall is enabled (sudo ufw enable) on mysql server machine, do the following to open port 3306 for remote access:

sudo ufw allow 3306

check status using

sudo ufw status

4) Once a remote connection is established, it can be verified in either client or server machine using commands

netstat -an | grep 3306
netstat -an | grep -i established

Per the Android docs SystemClock.elapsedRealtime() is the recommend basis for general purpose interval timing. This is because, per the documentation, elapsedRealtime() is guaranteed to be monotonic, [...], so is the recommend basis for general purpose interval timing.

The SystemClock documentation has a nice overview of the various time methods and the applicable use cases for them.

• SystemClock.elapsedRealtime() and SystemClock.elapsedRealtimeNanos() are the best bet for calculating general purpose elapsed time.
• SystemClock.uptimeMillis() and System.nanoTime() are another possibility, but unlike the recommended methods, they don't include time in deep sleep. If this is your desired behavior then they are fine to use. Otherwise stick with elapsedRealtime().
• Stay away from System.currentTimeMillis() as this will return "wall" clock time. Which is unsuitable for calculating elapsed time as the wall clock time may jump forward or backwards. Many things like NTP clients can cause wall clock time to jump and skew. This will cause elapsed time calculations based on currentTimeMillis() to not always be accurate.

When the game starts:

long startTime = SystemClock.elapsedRealtime();

When the game ends:

long endTime = SystemClock.elapsedRealtime();
long elapsedMilliSeconds = endTime - startTime;
double elapsedSeconds = elapsedMilliSeconds / 1000.0;

Also, Timer() is a best effort timer and will not always be accurate. So there will be an accumulation of timing errors over the duration of the game. To more accurately display interim time, use periodic checks to System.currentTimeMillis() as the basis of the time sent to setText(...).

Also, instead of using Timer, you might want to look into using TimerTask, this class is designed for what you want to do. The only problem is that it counts down instead of up, but that can be solved with simple subtraction.

What is a Servlet?

• A servlet is simply a class which responds to a particular type of network request - most commonly an HTTP request.
• Basically servlets are usually used to implement web applications - but there are also various frameworks which operate on top of servlets (e.g. Struts) to give a higher-level abstraction than the "here's an HTTP request, write to this HTTP response" level which servlets provide.

• Servlets run in a servlet container which handles the networking side (e.g. parsing an HTTP request, connection handling etc). One of the best-known open source servlet containers is Tomcat.

• In a request/response paradigm, a web server can serve only static pages to the client

• To serve dynamic pages, a we require Servlets.
• Servlet is nothing but a Java program
• This Java program doesn’t have a main method. It only has some callback methods.
• How does the web server communicate to the servlet? Via container or Servlet engine.
• Servlet lives and dies within a web container.
• Web container is responsible for invoking methods in a servlets. It knows what callback methods the Servlet has.

Flow of Request

• Client sends HTTP request to Web server
• Web server forwards that HTTP request to web container.
• Since Servlet can not understand HTTP, its a Java program, it only understands objects, so web container converts that request into valid request object
• Web container spins a thread for each request
• All the business logic goes inside doGet() or doPost() callback methods inside the servlets
• Servlet builds a Java response object and sends it to the container. It converts that to HTTP response again to send it to the client

How does the Container know which Servlet client has requested for?

• There’s a file called web.xml
• This is the master file for a web container

• You have information about servlet in this file-

  • servlets
    • Servlet-name
    • Servlet-class
  • servlet-mappings- the path like /Login or /Notifications is mapped here in
    • Servlet-name
    • url-pattern
  • and so on

• Every servlet in the web app should have an entry into this file

• So this lookup happens like- url-pattern -> servlet-name -> servlet-class

How to "install" Servlets? * Well, the servlet objects are inherited from the library- javax.servlet.* . Tomcat and Spring can be used to utilize these objects to fit the use case.

Ref- Watch this on 1.5x- https://www.youtube.com/watch?v=tkFRGdUgCsE . This has an awesome explanation.

A variable cannot be both null and undefined at the same time. However, the direct answer to your question is:

if (variable != null)

One =, not two.

There are two special clauses in the "abstract equality comparison algorithm" in the JavaScript spec devoted to the case of one operand being null and the other being undefined, and the result is true for == and false for !=. Thus if the value of the variable is undefined, it's not != null, and if it's not null, it's obviously not != null.

Now, the case of an identifier not being defined at all, either as a var or let, as a function parameter, or as a property of the global context is different. A reference to such an identifier is treated as an error at runtime. You could attempt a reference and catch the error:

var isDefined = false;
try {
  (variable);
  isDefined = true;
}
catch (x) {}

I would personally consider that a questionable practice however. For global symbols that may or may be there based on the presence or absence of some other library, or some similar situation, you can test for a window property (in browser JavaScript):

var isJqueryAvailable = window.jQuery != null;

or

var isJqueryAvailable = "jQuery" in window;

It sounds like you are almost definitely behind a proxy server.

Where this does not work for me behind my proxy:

svn checkout http://v8.googlecode.com/svn/trunk/ v8-read-only

this does:

svn --config-option servers:global:http-proxy-host=MY_PROXY_HOST --config-option servers:global:http-proxy-port=MY_PROXY_PORT checkout http://v8.googlecode.com/svn/trunk/ v8-read-only

UPDATE I forgot to quote my source :-)

http://svnbook.red-bean.com/en/1.1/ch07.html#svn-ch-7-sect-1.3.1

I think this can be useful. this was simple CSS selector.

hr { background-color: red; height: 1px; border: 0; }

<hr>

I had a similar issue, when I upgraded to the latest version of Android Studio 1.3.2. What seemed to work for me was removing the .gradle folder from my project directory:

rm -rf ~/project/.gradle

If you don't want to SELECT SLEEP(1);, you can also DO SLEEP(1); It's useful for those situations in procedures where you don't want to see output.

e.g.

SELECT ...
DO SLEEP(5);
SELECT ...

You can access your methods in the Ruby on Rails console like the following:

controller.method_name
helper.method_name

It seems like one closing brace is missing at ,right(a2.chdlm,2)))) from sysibm.sysdummy1 a1,

So your Query will be

select days(current date) - days(date(select concat(concat(concat(concat(left(a2.chdlm,4),'-'),substr(a2.chdlm,4,2)),'-'),right(a2.chdlm,2)))) from sysibm.sysdummy1 a1, chcart00 a2 where chstat = '05';

How large is length? You may do better to re-use a fixed sized (moderately large, but not obscene) buffer, and forget BinaryReader... just use Stream.Read and Stream.Write.

(edit) something like:

private static void copy(string srcFile, string dstFile, int offset,
     int length, byte[] buffer)
{
    using(Stream inStream = File.OpenRead(srcFile))
    using (Stream outStream = File.OpenWrite(dstFile))
    {
        inStream.Seek(offset, SeekOrigin.Begin);
        int bufferLength = buffer.Length, bytesRead;
        while (length > bufferLength &&
            (bytesRead = inStream.Read(buffer, 0, bufferLength)) > 0)
        {
            outStream.Write(buffer, 0, bytesRead);
            length -= bytesRead;
        }
        while (length > 0 &&
            (bytesRead = inStream.Read(buffer, 0, length)) > 0)
        {
            outStream.Write(buffer, 0, bytesRead);
            length -= bytesRead;
        }
    }        
}

In Android Studio IDE, you have to click the Filter icon to show expert properties. Then you will see the textAllCaps property. Check it, then uncheck it.

I would typically do something like this (onblur), but it could be attached to any of the events:

    if(!isNaN(sender.value)){
        if(sender.value > 100 )
            sender.value = 100;
        if(sender.value < 0 )
            sender.value = 0;
    }else{
          sender.value = 0;
    }
}

</script>
</head>

onNewIntent() is meant as entry point for singleTop activities which already run somewhere else in the stack and therefore can't call onCreate(). From activities lifecycle point of view it's therefore needed to call onPause() before onNewIntent(). I suggest you to rewrite your activity to not use these listeners inside of onNewIntent(). For example most of the time my onNewIntent() methods simply looks like this:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // getIntent() should always return the most recent
    setIntent(intent);
}

With all setup logic happening in onResume() by utilizing getIntent().

Limit the length of characters in a regular expression? ^[a-z]{6,15}$'

Limit length of characters or Numbers in a regular expression? ^[a-z | 0-9]{6,15}$'

++[[]][+[]] => 1 // [+[]] = [0], ++0 = 1
[+[]] => [0]

Then we have a string concatenation

1+[0].toString() = 10

I think your questions will all be answered if you understand how Sets, and in particular HashSets work. A set is a collection of unique objects, with Java defining uniqueness in that it doesn't equal anything else (equals returns false).

The HashSet takes advantage of hashcodes to speed things up. It assumes that two objects that equal eachother will have the same hash code. However it does not assume that two objects with the same hash code mean they are equal. This is why when it detects a colliding hash code, it only compares with other objects (in your case one) in the set with the same hash code.

For using DISTINCT keyword, you can use it like this:

SELECT DISTINCT 
    (SELECT min(ti.Country_id) 
     FROM tbl_countries ti 
     WHERE t.country_title = ti.country_title) As Country_id
    , country_title
FROM 
    tbl_countries t

For using ROW_NUMBER(), you can use it like this:

SELECT 
    Country_id, country_title 
FROM (
    SELECT *, ROW_NUMBER() OVER (PARTITION BY country_title ORDER BY Country_id) As rn
    FROM tbl_countries) t
WHERE rn = 1

Also with using LEFT JOIN, you can use this:

SELECT t1.Country_id, t1.country_title
FROM tbl_countries t1
    LEFT OUTER JOIN
    tbl_countries t2 ON t1.country_title = t2.country_title AND t1.Country_id > t2.Country_id
WHERE
    t2.country_title IS NULL

And with using of EXISTS, you can try:

SELECT t1.Country_id, t1.country_title
FROM tbl_countries t1   
WHERE
    NOT EXISTS (SELECT 1 
                FROM tbl_countries t2 
                WHERE t1.country_title = t2.country_title AND t1.Country_id > t2.Country_id)

values = new float[] { 0.1f, 0.2f, 0.3f };

This is a ternary operator, it's basically an inline if statement

x ? y : z

works like

if(x) y else z

except, instead of statements you have expressions; so you can use it in the middle of a more complex statement.

It's useful for writing succinct code, but can be overused to create hard to maintain code.

If you don't want to modify the Makefile itself, you can use --eval to add a new target, and then execute the new target, e.g.

make --eval='print-tests: @echo TESTS $(TESTS) ' print-tests

You can insert the required TAB character in the command line using CTRL-V, TAB

example Makefile from above:

all: do-something

TESTS=
TESTS+='a'
TESTS+='b'
TESTS+='c'

do-something:
        @echo "doing something"
        @echo "running tests $(TESTS)"
        @exit 1

SARose's answer worked for me until I updated from Ubuntu 20.04 LTS. The slight change I made to his code makes it work on the latest Ubuntu release.

import subprocess

def find_files(file_name):
    command = ['locate'+ ' ' + file_name]
    output = subprocess.Popen(command, stdout=subprocess.PIPE, shell=True).communicate()[0]
    output = output.decode()
    search_results = output.split('\n')
    return search_results

if ( $('#myfav').children().length > 0 ) {
     // do something
}

This should work. The children() function returns a JQuery object that contains the children. So you just need to check the size and see if it has at least one child.

The Array.prototype property represents the prototype for the Array constructor and allows you to add new properties and methods to all Array objects. we can create a prototype for this purpose

Array.prototype.has_element = function(element) {
    return $.inArray( element, this) !== -1;
};

And then use it like this

var numbers= [1, 2, 3, 4];
numbers.has_element(3) => true
numbers.has_element(10) => false

See the Demo below

Array.prototype.has_element = function(element) {_x000D_
  return $.inArray(element, this) !== -1;_x000D_
};_x000D_
_x000D_
_x000D_
_x000D_
var numbers = [1, 2, 3, 4];_x000D_
console.log(numbers.has_element(3));_x000D_
console.log(numbers.has_element(10));

1. Select cell B3 and click the Conditional Formatting button in the ribbon and choose "New Rule".
2. Select "Use a formula to determine which cells to format"
3. Enter the formula: =IF(B2="X",IF(B3="Y", TRUE, FALSE),FALSE), and choose to fill green when this is true
4. Create another rule and enter the formula =IF(B2="X",IF(B3="W", TRUE, FALSE),FALSE) and choose to fill red when this is true.

More details - conditional formatting with a formula applies the format when the formula evaluates to TRUE. You can use a compound IF formula to return true or false based on the values of any cells.

I saw your answers and I used include path with syntax

require_once '../file.php'; // server internal error 500

and http server (Apache 2.4.3) returned internal error 500.

When I changed the path to

require_once '/../file.php'; // OK

everything is fine.

Btw, the reason that you're having trouble is that the java compiler recognizes two version flags. There is -source 1.5, which assumes java 1.5 level source code, and -target 1.5, which will emit java 1.5 compatible class files. You'll probably want to use both of these switches, but you definitely need -target 1.5; try double checking that eclipse is doing the right thing.

Send a POST request from A. Post requests are on the serverside only and can't be accessed by the client.

You can send a POST request from a.com to b.com using CURL (recommended, serverside) or a hidden method="POST" form (clientside). If you go for the latter, you might want to obfuscate your JavaScript so that the user won't be able to understand the algorithm and interfere with it.

Make a gateway on b.com to set cookies:

<?php
    if (isset($_POST['data']) {
        setcookie('a', $_POST['data']);
        header("Location: b.com/landingpage");
    }
?>

If you want to bring security a step further, implement a function on both sides (a.com and b.com) to encrypt (on a.com) and decrypt (on b.com) data using a cryptographic cypher.

If you're trying to do something that must be absolutely secure (e.g. transfer a login session) try oAuth or take some inspiration from https://api.cloudianos.com/docs#v2/auth

Facebook uses a very clever technique I described in context of my scrollbar plugin jsFancyScroll:

The scrolled content is actually scrolled natively by the browser scrolling mechanisms while the native scrollbar is hidden by using overflow definitions and the custom scrollbar is kept in sync by bi-directional event listening.

Feel free to use my plugin for your project: :)

https://github.com/leoselig/jsFancyScroll/

I highly recommend it over plugins such as TinyScrollbar that come with terrible performance issues!

In a similar use case, this worked for me...

<button onclick="window.open('https://www.w3.org/', '_blank');">  My Button </button>

Take the width of the table and divide it by the number of cell ().

PerformanceTable {width:500px;}    
PerformanceTable.td {width:100px;}

If the table dynamically widens or shrinks you could dynamically increase the cell size with a little javascript.

If only you want the first letter:

>>> 'hello world'.capitalize()
'Hello world'

But to capitalize each word:

>>> 'hello world'.title()
'Hello World'

mybytestring.encode(somecodec) is meaningful for these values of somecodec:

• base64
• bz2
• zlib
• hex
• quopri
• rot13
• string_escape
• uu

I am not sure what decoding an already decoded unicode text is good for. Trying that with any encoding seems to always try to encode with the system's default encoding first.

This is possible if you have an existing Newline character in the row or another row.

Select the square-box that represents the existing Newline character, copy it (control-C), and then paste it (control-V) where you want it to be.

This is slightly cheesy, but I actually did get it to work in SSMS 2008 and I was not able to get any of the other suggestions (control-enter, alt-13, or any alt-##) to work.

The JSON format worked for me quite well. The standard library offers methods to write the data structure indented, so it is quite readable.

See also this golang-nuts thread.

The benefits of JSON are that it is fairly simple to parse and human readable/editable while offering semantics for lists and mappings (which can become quite handy), which is not the case with many ini-type config parsers.

Example usage:

conf.json:

{
    "Users": ["UserA","UserB"],
    "Groups": ["GroupA"]
}

Program to read the configuration

import (
    "encoding/json"
    "os"
    "fmt"
)

type Configuration struct {
    Users    []string
    Groups   []string
}

file, _ := os.Open("conf.json")
defer file.Close()
decoder := json.NewDecoder(file)
configuration := Configuration{}
err := decoder.Decode(&configuration)
if err != nil {
  fmt.Println("error:", err)
}
fmt.Println(configuration.Users) // output: [UserA, UserB]

You'll need to download SLF4J's jars from the official site as either a zip (v1.7.4) or tar.gz (v1.7.4)

The download contains multiple jars based on how you want to use SLF4J. If you're simply trying to resolve the requirement of some other library (GWT, I assume) and don't really care about using SLF4J correctly, then I would probably pick the slf4j-api-1.7.4.jar since the Simple jar suggested by another answer does not contain, to my knowledge, the specific class you're looking for.

You have to include sort function which is in algorithm header file which is a standard template library in c++.

Usage: std::sort(str.begin(), str.end());

#include <iostream>
#include <algorithm>  // this header is required for std::sort to work
int main()
{
    std::string s = "dacb";
    std::sort(s.begin(), s.end());
    std::cout << s << std::endl;

    return 0;
}

OUTPUT:

abcd

1. Open the created task scheduler

2. switch to the “Action” tab and select your created “Action”

3. In the Edit section, using the browser you could select powershell.exe in your system32\WindowsPowerShell\v1.0 folder.

      Example -C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
   

4. Next, in the ‘Add arguments’ -File parameter, paste your script file path in your system.

       Example – c:\GetMFAStatus.ps1
   

This blog might help you to automate your Powershell scripts with windows task scheduler

Late to the party, but this may help anyone looking for a quick solution:

you can use bin(ord('b')).replace('b', '')bin() it gives you the binary representation with a 'b' after the last bit, you have to remove it. Also ord() gives you the ASCII number to the char or 8-bit/1 Byte coded character.

Cheers

I found the reason. If you remove update panels it woks fine!

case_when(), which was added to dplyr in May 2016, solves this problem in a manner similar to memisc::cases().

For example:

library(dplyr)
mtcars %>% 
  mutate(category = case_when(
    .$cyl == 4 & .$disp < median(.$disp) ~ "4 cylinders, small displacement",
    .$cyl == 8 & .$disp > median(.$disp) ~ "8 cylinders, large displacement",
    TRUE ~ "other"
  )
)

As of dplyr 0.7.0,

mtcars %>% 
  mutate(category = case_when(
    cyl == 4 & disp < median(disp) ~ "4 cylinders, small displacement",
    cyl == 8 & disp > median(disp) ~ "8 cylinders, large displacement",
    TRUE ~ "other"
  )
)

Performance

Today 2020.03.06 I perform tests of chosen solutions on Chrome v80.0, Safari v13.0.5 and Firefox 73.0.1 on MacOs High Sierra v10.13.6

Conclusions

• solutions based on for-in (A,B) are fast (or fastest) for all browsers for big and small objects
• surprisingly for-of (H) solution is fast on chrome for small and big objects
• solutions based on explicit index i (J,K) are quite fast on all browsers for small objects (for firefox also fast for big ojbects but medium fast on other browsers)
• solutions based on iterators (D,E) are slowest and not recommended
• solution C is slow for big objects and medium-slow for small objects

Details

Performance tests was performed for

• small object - with 3 fields - you can perform test on your machine HERE
• 'big' object - with 1000 fields - you can perform test on your machine HERE

You can send email without Outlook in VBScript using the CDO.Message object. You will need to know the address of your SMTP server to use this:

Set MyEmail=CreateObject("CDO.Message")

MyEmail.Subject="Subject"
MyEmail.From="[email protected]"
MyEmail.To="[email protected]"
MyEmail.TextBody="Testing one two three."

MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing")=2

'SMTP Server
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver")="smtp.server.com"

'SMTP Port
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25 

MyEmail.Configuration.Fields.Update
MyEmail.Send

set MyEmail=nothing

If your SMTP server requires a username and password then paste these lines in above the MyEmail.Configuration.Fields.Update line:

'SMTP Auth (For Windows Auth set this to 2)
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate")=1
'Username
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusername")="username" 
'Password
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendpassword")="password"

More information on using CDO to send email with VBScript can be found on the link below: http://www.paulsadowski.com/wsh/cdo.htm

Others have already said that date literals in SQL Server require being surrounded with single quotes, but I wanted to add that you can solve your month/day mixup problem two ways (that is, the problem where 25 is seen as the month and 5 the day) :

1. Use an explicit Convert(datetime, 'datevalue', style) where style is one of the numeric style codes, see Cast and Convert. The style parameter isn't just for converting dates to strings but also for determining how strings are parsed to dates.

2. Use a region-independent format for dates stored as strings. The one I use is 'yyyymmdd hh:mm:ss', or consider ISO format, yyyy-mm-ddThh:mi:ss.mmm. Based on experimentation, there are NO other language-invariant format string. (Though I think you can include time zone at the end, see the above link).

I read a piece with a comment that states the following commands can be run now. I have not tested myself so be careful.

$ yum install -y epel-release
$ yum install -y python36

I have tried all the above steps mentioned but nothing worked for me. Finally, restarting the computer worked for this issue :D

I'd suggest:

document.querySelector('.rateRecipe.btns-one-small').click();

The above code assumes that the given element has both of those classes; otherwise, if the space is meant to imply an ancestor-descendant relationship:

document.querySelector('.rateRecipe .btns-one-small').click();

The method getElementsByClassName() takes a single class-name (rather than document.querySelector()/document.querySelectorAll(), which take a CSS selector), and you passed two (presumably class-names) to the method.

References:

• document.getElementsByClassName().
• document.querySelector().

You can try following way

<input type= "file" name="Upload" accept = "application/pdf,.csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel">

OR (in asp.net mvc)

@Html.TextBoxFor(x => x.FileName, new { @id = "doc", @type = "file", @accept = "application/pdf,.csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" })

Sometime in the future Comment out the following code in web.config

 <!--<system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />

    </compilers>
  </system.codedom>-->

update the to the following code.

<system.web>
    <authentication mode="None" />
    <compilation debug="true" targetFramework="4.6.1" />
    <httpRuntime targetFramework="4.6.1" />
    <customErrors mode="Off"/>
    <trust level="Full"/>
  </system.web>

Also worth noting that WinFlexBison has been packaged for the Chocolatey package manager. Install that and then go:

choco install winflexbison

...which at the time of writing contains Bison 2.7 & Flex 2.6.3.

There is also winflexbison3 which (at the time of writing) has Bison 3.0.4 & Flex 2.6.3.

When you write the statement

*src = "anotherstring";

the compiler sees the constant string "abcdefghijklmnop" like an array. Imagine you had written the following code instead:

char otherstring[14] = "anotherstring";
...
*src = otherstring;

Now, it's a bit clearer what is going on. The left-hand side, *src, refers to a char (since src is of type pointer-to-char) whereas the right-hand side, otherstring, refers to a pointer.

This isn't strictly forbidden because you may want to store the address that a pointer points to. However, an explicit cast is normally used in that case (which isn't too common of a case). The compiler is throwing up a red flag because your code is likely not doing what you think it is.

It appears to me that you are trying to assign a string. Strings in C aren't data types like they are in C++ and are instead implemented with char arrays. You can't directly assign values to a string like you are trying to do. Instead, you need to use functions like strncpy and friends from <string.h> and use char arrays instead of char pointers. If you merely want the pointer to point to a different static string, then drop the *.

I don't like the other solution and I created my own. With this solution you can't enter more than MAX_BEFORE_POINT digit before the point and the decimals can't be more than MAX_DECIMAL.

You just can't type the digit in excess, no other effects! In additional if you write "." it types "0."

1. Set the EditText in the layout to:

   android:inputType="numberDecimal"

2. Add the Listener in your onCreate. If you want modify the number of digits before and after the point edit the call to PerfectDecimal(str, NUMBER_BEFORE_POINT, NUMBER_DECIMALS), here is set to 3 and 2

   EditText targetEditText = (EditText)findViewById(R.id.targetEditTextLayoutId);
   
   targetEditText.addTextChangedListener(new TextWatcher() {
     public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {}
   
     public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {}
   
     public void afterTextChanged(Editable arg0) {
       String str = targetEditText.getText().toString();
       if (str.isEmpty()) return;
       String str2 = PerfectDecimal(str, 3, 2);
   
       if (!str2.equals(str)) {
           targetEditText.setText(str2);
           targetEditText.setSelection(str2.length());
       }
     }
   });
   

3. Include this Funcion:

   public String PerfectDecimal(String str, int MAX_BEFORE_POINT, int MAX_DECIMAL){
     if(str.charAt(0) == '.') str = "0"+str;
     int max = str.length();
   
     String rFinal = "";
     boolean after = false;
     int i = 0, up = 0, decimal = 0; char t;
     while(i < max){
       t = str.charAt(i);
       if(t != '.' && after == false){
           up++;
           if(up > MAX_BEFORE_POINT) return rFinal;
       }else if(t == '.'){
           after = true;
       }else{
           decimal++;
           if(decimal > MAX_DECIMAL)
               return rFinal;
       }
       rFinal = rFinal + t;
       i++;
     }return rFinal;
   }
   

And it's done!

Using   instead of spaces will prevent a break.

<span>I&nbsp;DONT&nbsp;WANT&nbsp;TO&nbsp;BREAK&nbsp;THIS&nbsp;LINE&nbsp;UP, but this text can be on any line.</span>

store all your data initially

function PhoneListCtrl($scope, $http) {
  $http.get('phones/phones.json').success(function(data) {
    $scope.phones = data.splice(0, 5);
    $scope.allPhones = data;
  });

  $scope.orderProp = 'age';
  $scope.howMany = 5;
  //then here watch the howMany variable on the scope and update the phones array accordingly
  $scope.$watch("howMany", function(newValue, oldValue){
    $scope.phones = $scope.allPhones.splice(0,newValue)
  });
}

EDIT had accidentally put the watch outside the controller it should have been inside.

It is apparently possible to manually install offline voice recognition by downloading the files directly and installing them in the right locations manually. I guess this is just a way to bypass Google hardware requirements. However, personally I didn't have to reboot or anything, simply changing to UK and back again did it.

Only works in IE:

window.open ("mapage.html","","fullscreen=yes");  
window.open('','_parent','');  
window.close();

From the Java API of CharSequence:

A CharSequence is a readable sequence of characters. This interface provides uniform, read-only access to many different kinds of character sequences.

This interface is then used by String, CharBuffer and StringBuffer to keep consistency for all method names.

I believe it means 'anything but a whitespace character'.

Make sure you've set your target API (different from the target SDK) in the Project Properties (not the manifest) to be at least 4.0/API 14.

_{This answer is meant to be a rather short and sweet one to answer (part of) the titled question. If you want an answer with more detail that explains why you have to put them there, please go here.}

The general rule for putting the typename keyword is mostly when you're using a template parameter and you want to access a nested typedef or using-alias, for example:

template<typename T>
struct test {
    using type = T; // no typename required
    using underlying_type = typename T::type // typename required
};

Note that this also applies for meta functions or things that take generic template parameters too. However, if the template parameter provided is an explicit type then you don't have to specify typename, for example:

template<typename T>
struct test {
    // typename required
    using type = typename std::conditional<true, const T&, T&&>::type;
    // no typename required
    using integer = std::conditional<true, int, float>::type;
};

The general rules for adding the template qualifier are mostly similar except they typically involve templated member functions (static or otherwise) of a struct/class that is itself templated, for example:

Given this struct and function:

template<typename T>
struct test {
    template<typename U>
    void get() const {
        std::cout << "get\n";
    }
};

template<typename T>
void func(const test<T>& t) {
    t.get<int>(); // error
}

Attempting to access t.get<int>() from inside the function will result in an error:

main.cpp:13:11: error: expected primary-expression before 'int'
     t.get<int>();
           ^
main.cpp:13:11: error: expected ';' before 'int'

Thus in this context you would need the template keyword beforehand and call it like so:

t.template get<int>()

That way the compiler will parse this properly rather than t.get < int.

from msdn Do not use a variable in a SELECT statement to concatenate values (that is, to compute aggregate values). Unexpected query results may occur. This is because all expressions in the SELECT list (including assignments) are not guaranteed to be executed exactly once for each output row

The above seems to say that concatenation as done above is not valid as the assignment might be done more times than there are rows returned by the select

You can also use tables to accomplish this, like:

.pdf {
  display: table;
}
.pdf:before {
  display: table-cell;
  vertical-align: middle;
}

Here is an example: https://jsfiddle.net/ar9fadd0/2/

EDIT: You can also use flex to accomplish this:

.pdf {
  display: flex;
}
.pdf:before {
  display: flex;
  align-items: center;
}

Here is an example: https://jsfiddle.net/ctqk0xq1/1/

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm service.

The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.

To restart the service:

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart        # typical
/etc/init.d/php5-fpm restart       # debian-style
/etc/init.d/php7.0-fpm restart     # debian-style PHP 7

Using service wrapper script

service php-fpm restart        # typical
service php5-fpm restart       # debian-style
service php7.0-fpm restart.    # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service        # typical
systemctl restart php5-fpm.service       # uncommon
systemctl restart php7.0-fpm.service     # uncommon PHP 7

Or whatever the equivalent is on your system.

The above commands taken directly from this server fault answer

The autoload config does start below the vendor dir. So you might want change the vendor dir, e.g.

{
    "config": {
        "vendor-dir": "../vendor/"
    },
    "autoload": {
        "psr-0": {"AppName": "src/"}
    }
}

Or isn't this possible in your project?

To load data from text file or csv file the command is

load data local infile 'file-name.csv'
into table table-name
fields terminated by '' enclosed by '' lines terminated by '\n' (column-name);

In above command, in my case there is only one column to be loaded so there is no "terminated by" and "enclosed by" so I kept it empty else programmer can enter the separating character . for e.g . ,(comma) or " or ; or any thing.

**for people who are using mysql version 5 and above **

Before loading the file into mysql must ensure that below tow line are added in side etc/mysql/my.cnf

to edit my.cnf command is

sudo vi /etc/mysql/my.cnf

[mysqld]  
local-infile

[mysql]  
local-infile  

Good question... I find that coders typically use the declaration to declare defaults. I've been held to one way (or warned) or the other too based on the compiler

void testFunct(int nVal1, int nVal2=500);
void testFunct(int nVal1, int nVal2)
{
    using namespace std;
    cout << nVal1 << << nVal2 << endl;
}

On a related note, if you have copied a project or in anycase, have the same context path for 2 'active' projects, you have to change the context path of one of them, then clean the tomcat server settings, then republish the servers

see this in-more detailed answer

Just to add a bit of extra info over the right solution. Be aware that you'll need this class org.apache.catalina.filters.CorsFilter. So in order to have it, if your tomcat is not 7.0.41 or higher, download 'tomcat-catalina.7.0.41.jar' or higher ( you can do it from http://mvnrepository.com/artifact/org.apache.tomcat/tomcat-catalina ) and put it in the 'lib' folder inside Tomcat installation folders. I actually used 7.0.42 Hope it helps!

I faced this issue because my $(elem).click(function(){}); script was placed inline in a div that was set to style="display:none;".

When the css display was switched to block, the script would add the event listener a second time. I moved the script to a separate .js file and the duplicate event listener was no longer initiated.

You need to declare disconnectFunc as a function pointer, not a void pointer. You also need to call it as a function (with parentheses), and no "*" is needed.

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

You could filter the file through cat -n before piping to less:

cat -n file.txt | less

Or, if your version of less supports it, the -N option:

less -N file.txt

Here is a slightly modified version of t.dubrownik's answer. Why?

1. As a general template, you should return the return value from the original function.
2. This changes the name of the function, which could affect other decorators / code.

So use @functools.wraps():

from functools import wraps

def decorator(argument):
    def real_decorator(function):
        @wraps(function)
        def wrapper(*args, **kwargs):
            funny_stuff()
            something_with_argument(argument)
            retval = function(*args, **kwargs)
            more_funny_stuff()
            return retval
        return wrapper
    return real_decorator

The java.io.File and consorts acts on the local disk file system. The root cause of your problem is that relative paths in java.io are dependent on the current working directory. I.e. the directory from which the JVM (in your case: the webserver's one) is started. This may for example be C:\Tomcat\bin or something entirely different, but thus not C:\Tomcat\webapps\contextname or whatever you'd expect it to be. In a normal Eclipse project, that would be C:\Eclipse\workspace\projectname. You can learn about the current working directory the following way:

System.out.println(new File(".").getAbsolutePath());

However, the working directory is in no way programmatically controllable. You should really prefer using absolute paths in the File API instead of relative paths. E.g. C:\full\path\to\file.ext.

You don't want to hardcode or guess the absolute path in Java (web)applications. That's only portability trouble (i.e. it runs in system X, but not in system Y). The normal practice is to place those kind of resources in the classpath, or to add its full path to the classpath (in an IDE like Eclipse that's the src folder and the "build path" respectively). This way you can grab them with help of the ClassLoader by ClassLoader#getResource() or ClassLoader#getResourceAsStream(). It is able to locate files relative to the "root" of the classpath, as you by coincidence figured out. In webapplications (or any other application which uses multiple classloaders) it's recommend to use the ClassLoader as returned by Thread.currentThread().getContextClassLoader() for this so you can look "outside" the webapp context as well.

Another alternative in webapps is the ServletContext#getResource() and its counterpart ServletContext#getResourceAsStream(). It is able to access files located in the public web folder of the webapp project, including the /WEB-INF folder. The ServletContext is available in servlets by the inherited getServletContext() method, you can call it as-is.

Here is another solution that's pretty simple to implement (and pretty fast, too). It will catch all intersections, including when the sphere has fully entered the rectangle.

// clamp(value, min, max) - limits value to the range min..max

// Find the closest point to the circle within the rectangle
float closestX = clamp(circle.X, rectangle.Left, rectangle.Right);
float closestY = clamp(circle.Y, rectangle.Top, rectangle.Bottom);

// Calculate the distance between the circle's center and this closest point
float distanceX = circle.X - closestX;
float distanceY = circle.Y - closestY;

// If the distance is less than the circle's radius, an intersection occurs
float distanceSquared = (distanceX * distanceX) + (distanceY * distanceY);
return distanceSquared < (circle.Radius * circle.Radius);

With any decent math library, that can be shortened to 3 or 4 lines.

CREATE VIEW MyView AS
   SELECT Column, Value FROM Table;


SELECT Column FROM MyView WHERE Value = 1;

Is the proper solution in MySQL, some other SQLs let you define Views more exactly.

Note: Unless the View is very complicated, MySQL will optimize this just fine.

Travis R is correct. (I wish I could upvote ya.) I just got this working myself. With these routes:

resources :articles do
  resources :comments
end

You get paths like:

/articles/42
/articles/42/comments/99

routed to controllers at

app/controllers/articles_controller.rb
app/controllers/comments_controller.rb

just as it says at http://guides.rubyonrails.org/routing.html#nested-resources, with no special namespaces.

But partials and forms become tricky. Note the square brackets:

<%= form_for [@article, @comment] do |f| %>

Most important, if you want a URI, you may need something like this:

article_comment_path(@article, @comment)

Alternatively:

[@article, @comment]

as described at http://edgeguides.rubyonrails.org/routing.html#creating-paths-and-urls-from-objects

For example, inside a collections partial with comment_item supplied for iteration,

<%= link_to "delete", article_comment_path(@article, comment_item),
      :method => :delete, :confirm => "Really?" %>

What jamuraa says may work in the context of Article, but it did not work for me in various other ways.

There is a lot of discussion related to nested resources, e.g. http://weblog.jamisbuck.org/2007/2/5/nesting-resources

Interestingly, I just learned that most people's unit-tests are not actually testing all paths. When people follow jamisbuck's suggestion, they end up with two ways to get at nested resources. Their unit-tests will generally get/post to the simplest:

# POST /comments
post :create, :comment => {:article_id=>42, ...}

In order to test the route that they may prefer, they need to do it this way:

# POST /articles/42/comments
post :create, :article_id => 42, :comment => {...}

I learned this because my unit-tests started failing when I switched from this:

resources :comments
resources :articles do
  resources :comments
end

to this:

resources :comments, :only => [:destroy, :show, :edit, :update]
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

I guess it's ok to have duplicate routes, and to miss a few unit-tests. (Why test? Because even if the user never sees the duplicates, your forms may refer to them, either implicitly or via named routes.) Still, to minimize needless duplication, I recommend this:

resources :comments
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

Sorry for the long answer. Not many people are aware of the subtleties, I think.

A TortoiseSVN equivalent solution of the accepted answer (I had written this in an internal document for my company as we are newly adopting SVN) follows. I thought it would be helpful to share here as well:

Checking out a single file: Subversion does not support checkout of a single file, it only supports checkout of directory structures. (Reference: http://subversion.tigris.org/faq.html#single-file-checkout). This is because with every directory that is checked out as a working copy, the metadata regarding modifications/file revisions is stored as an internal hidden folder (.svn/_svn). This is not supported currently (v1.6) for single files.

Alternate recommended strategy: You will have to do the checkout directory part only once, following that you can directly go and checkout your single files. Do a sparse checkout of the parent folder and directory structure. A sparse checkout is basically checking out only the folder structure without populating the content files. So you checkout only the directory structures and need not checkout ALL the files as was the concern. Reference: http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-checkout.html

Step 1: Proceed to repository browser

Step 2: Right click the parent folder within the repository containing all the files that you wish to work on and Select Checkout.

Step 3: Within new popup window, ensure that the checkout directory points to the correct location on your local PC. There will also be a dropdown menu labeled “checkout depth”. Choose “Only this item” or “Immediate children, including folders” depending on your requirement. Second option is recommended as, if you want to work on nested folder, you can directly proceed the next time otherwise you will have to follow this whole procedure again for the nested folder.

Step 4: The parent folder(s) should now be available within your locally chosen folder and is now being monitored with SVN (a hidden folder “.svn” or “_svn” should now be present). Within the repository now, right click the single file that you wish to have checked out alone and select the “Update Item to revision” option. The single file can now be worked on and checked back into the repository.

I hope this helps.

Since I'm a dunce, I thought it would be good to have some working code.

Also, Angular2 typings version of angular-protractor has issues with the jQuery $, so the top accepted answer doesn't give me a clean compile.

Here are the steps that I got to be working:

You can not get hive version from command line.

You can checkout hadoop version as mentioned by Dave.

Also if you are using cloudera distribution, then look directly at the libs:

ls /usr/lib/hive/lib/ and check for hive library

hive-hwi-0.7.1-cdh3u3.jar

You can also check the compatible versions here:

http://www.cloudera.com/content/cloudera/en/documentation/cdh5/v5-1-x/CDH-Version-and-Packaging-Information/CDH-Version-and-Packaging-Information.html

StringBuffer sb = new SringBuffer();
// do something wiht it

i think this code is faster.

public class DatePickerActivity extends AppCompatActivity {
    Button button;
    static TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button= (Button) findViewById(R.id.btn_click);

            }
        });

    }

For Django in django.test.TestCase unit testing, I changed my Python2 syntax:

def test_view(self):
    response = self.client.get(reverse('myview'))
    self.assertIn(str(self.obj.id), response.content)
    ...

To use the Python3 .decode('utf8') syntax:

def test_view(self):
    response = self.client.get(reverse('myview'))
    self.assertIn(str(self.obj.id), response.content.decode('utf8'))
    ...

I think you're looking for: SELECT a, b, COUNT(a) FROM tbl GROUP BY a, b

Do NOT use timestamp to make an unique URL as for every page you visit is cached in DOM by jquery mobile and you soon run into trouble of running out of memory on mobiles.

$jqm(document).bind('pagebeforeload', function(event, data) {
    var url = data.url;
    var savePageInDOM = true;

    if (url.toLowerCase().indexOf("vacancies") >= 0) {
        savePageInDOM = false;
    }

    $jqm.mobile.cache =  savePageInDOM;
})

This code activates before page is loaded, you can use url.indexOf() to determine if the URL is the one you want to cache or not and set the cache parameter accordingly.

Do not use window.location = ""; to change URL otherwise you will navigate to the address and pagebeforeload will not fire. In order to get around this problem simply use window.location.hash = "";

Okay, I found spencerlyon2's answer working. However, in case anybody would find himself/herself not knowing what to do with that one line, I had to do it this way:

beingsaved = plt.figure()

# Some scatter plots
plt.scatter(X_1_x, X_1_y)
plt.scatter(X_2_x, X_2_y)

beingsaved.savefig('destination_path.eps', format='eps', dpi=1000)

Despite all the explanations, LEA is an arithmetic operation:

LEA Rt, [Rs1+a*Rs2+b] =>  Rt = Rs1 + a*Rs2 + b

It's just that its name is extremelly stupid for a shift+add operation. The reason for that was already explained in the top rated answers (i.e. it was designed to directly map high level memory references).

UPDATE table1 SET (col1, col2) = (col2, col3) FROM othertable WHERE othertable.col1 = 123;

You can test it by using this snipped code:

private static void Main(string[] args)
{
   int threadCount = 0;
   try
   {
      for (int i = 0; i < int.MaxValue; i ++)
      {
         new Thread(() => Thread.Sleep(Timeout.Infinite)).Start();
         threadCount ++;
      }
   }
   catch
   {
      Console.WriteLine(threadCount);
      Console.ReadKey(true);
   }
}

Beware of 32-bit and 64-bit mode of application.

It is a bad idea to select * from anything, period. This is why SSMS adds every field name, even if there are hundreds, instead of select *. It is extremely inefficient regardless of how large the table is. If you don't know what the fields are, its still more efficient to pull them out of the INFORMATION_SCHEMA database than it is to select *.

A better query would be:

SELECT 
 COLUMN_NAME, 
 Case 
  When DATA_TYPE In ('varchar', 'char', 'nchar', 'nvarchar', 'binary') 
  Then convert(varchar(MAX), CHARACTER_MAXIMUM_LENGTH)  
  When DATA_TYPE In ('numeric', 'int', 'smallint', 'bigint', 'tinyint') 
  Then convert(varchar(MAX), NUMERIC_PRECISION) 
  When DATA_TYPE = 'bit' 
  Then convert(varchar(MAX), 1)
  When DATA_TYPE IN ('decimal', 'float') 
  Then convert(varchar(MAX), Concat(Concat(NUMERIC_PRECISION, ', '), NUMERIC_SCALE)) 
  When DATA_TYPE IN ('date', 'datetime', 'smalldatetime', 'time', 'timestamp') 
  Then '' 
 End As DATALEN, 
 DATA_TYPE 
FROM INFORMATION_SCHEMA.COLUMNS 
Where 
 TABLE_NAME = ''

You can simply write :

class A(object):

    def __init__(self):
        print "Initialiser A was called"

class B(A):

    def __init__(self):
        A.__init__(self)
        # A.__init__(self,<parameters>) if you want to call with parameters
        print "Initialiser B was called"

class C(B):

    def __init__(self):
        # A.__init__(self) # if you want to call most super class...
        B.__init__(self)
        print "Initialiser C was called"

In my case, I accidentally typed an unnecessary dot at the end of the config file which caused this strange problem. Please make sure your config file does not contain any errors!

Try this code,

$('#1').on('mousedown',function(e) {
   if (e.button==0 && e.ctrlKey) {
       alert('is Left Click');
   } else if (e.button==2 && e.ctrlKey){
       alert('is Right Click');
   }
});

Sorry I added e.ctrlKey.

You can with flexbox:

ul.list {
    padding: 0;
    list-style: none;
    display: flex;
    align-items: stretch;
    justify-items: center;
    flex-wrap: wrap;
    justify-content: center;
}
li {
    width: 100px;
    padding: .5rem;
    border-radius: 1rem;
    background: yellow;
    margin: 0 5px;
}

<ul class="list">
  <li>title 1</li>
  <li>title 2<br>new line</li>
  <li>title 3<br>new<br>line</li>
</ul>

Just in case you would also like check if a string (or a set of strings) contain(s) multiple sub-strings, you can also use the '|' between two substrings.

>substring="as|at"
>string_vector=c("ass","ear","eye","heat") 
>grepl(substring,string_vector)

You will get

[1]  TRUE FALSE FALSE  TRUE

since the 1st word has substring "as", and the last word contains substring "at"

I had a scenario, and this one helped me

JObject objParserd = JObject.Parse(jsonString);

JObject arrayObject1 = (JObject)objParserd["d"];

D myOutput= JsonConvert.DeserializeObject<D>(arrayObject1.ToString());

More simplified:

resultList.Remove(resultList.Single(x => x.Id == 2));

there is no needing to create a new var object.

you can use toggleClass() to toggle class it is really handy.

case:1

<div id='mydiv' class="class1"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class2"></div>

case:2

<div id='mydiv' class="class2"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class1"></div>

case:3

<div id='mydiv' class="class1 class2 class3"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class3"></div>

@Ian Nelson: I'm wondering if others see the problem there.

Let's say you have split fields. That's 70 characters total, 35 for first name and 35 for last name. However, if you have one field, you neglect the space that separates first and last names, short changing you by 1 character. Sure, it's "only" one character, but that could make the difference between someone entering their full name and someone not. Therefore, I would change that suggestion to "35 characters for each of Given Name and Family Name, or 71 characters for a single field to hold the Full Name".

I've had similar problems. If you work with Eclipse, you need to go to the folder where you have your src/ folder... If you used a package - then you use

javac -cp . packageName/className

which means if you've had a package named def and main class with name TextFrame.java you'd write

javac -cp . def/TextFrame

omitting the trailing .java extension, and then you run it with the

java def/TextFrame 

and if you have have arguments, then you need to supply it with arguments corresponding to your program. I hope this helps a bit.

Had the same problem when Load external without cache using Javascript

Load external <script> without cache using Javascript

Had a good solution for cache problem here:

https://www.c-sharpcorner.com/article/how-to-force-the-browser-to-reload-cached-js-css-files-to-reflect-latest-chan/

But this happend: Uncaught TypeError: Cannot read property 'appendChild' of null.

Here is good explanation: https://stackoverflow.com/a/58824439/14491024

As it said your script tag is in the head, the JavaScript is loaded before your HTML.

In Visual Studio by C# this problem is solved like this by adding Guid:

Here is how it looks in the View page source:

Use get(0) instead of html(). In other words, replace

doc.fromHTML($('#htmlTableId').html(), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

with

doc.fromHTML($('#htmlTableId').get(0), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

You Can use simply git checkout <commit hash>

in this sequence

bash git clone [URLTORepository] git checkout [commithash]

commit hash looks like this "45ef55ac20ce2389c9180658fdba35f4a663d204"

stat -c %s file.txt

This command will give you the size of the file in bytes. You can learn more about why you should avoid parsing output of ls command over here: http://mywiki.wooledge.org/ParsingLs

Use the built-in function round():

Out[23]: 66.6667

In [24]: round(1.29578293,6)
Out[24]: 1.295783

help on round():

round(number[, ndigits]) -> floating point number

Round a number to a given precision in decimal digits (default 0 digits). This always returns a floating point number. Precision may be negative.

I ran into the problem that some subdependencies couldn't be resolved in IntelliJ 2016.3.X. This could be fixed by changing the Maven home directory in Settings > Build, Execution, Deployment > Build Tools > Maven from Bundled (Maven 3) to /usr/share/maven.

After that all subdependencies got resolved as in previous IntelliJ versions.

Dang -- lbrandy beat me to the punch, but that doesn't mean I can't provide you with the system results for Vista!

The problem is that you are using getSystemResourceAsStream. Use simply getResourceAsStream. System resources load from the system classloader, which is almost certainly not the class loader that your jar is loaded into when run as a webapp.

It works in Eclipse because when launching an application, the system classloader is configured with your jar as part of its classpath. (E.g. java -jar my.jar will load my.jar in the system class loader.) This is not the case with web applications - application servers use complex class loading to isolate webapplications from each other and from the internals of the application server. For example, see the tomcat classloader how-to, and the diagram of the classloader hierarchy used.

EDIT: Normally, you would call getClass().getResourceAsStream() to retrieve a resource in the classpath, but as you are fetching the resource in a static initializer, you will need to explicitly name a class that is in the classloader you want to load from. The simplest approach is to use the class containing the static initializer, e.g.

[public] class MyClass {
  static
  {
    ...
    props.load(MyClass.class.getResourceAsStream("/someProps.properties"));
  }
}

Since lua 5.3 there is a new math.tointeger function for string to integer. Just for integer, no float.

For example:

print(math.tointeger("10.1")) -- nil
print(math.tointeger("10")) -- 10

If you want to convert integer and float, the tonumber function is more appropriate.

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

You can run npm commands directly in terminal (ctrl + `). Make sure that terminal has cmd.exe as the shell selected.

You can default cmd.exe as your shell by following these steps.

1. ctrl+Shift+p
2. Type > Select Default Shell + Enter
3. Select > Command Prompt ...cmd.exe
4. Restart VS Code.

Try this way of formation, it is rather fancy ...

Have a look at this jsfiddle

Button-Radio

The idea is to choose a the radio as a button instead of the normal circle image.

The first example doesn't work because you can't assign values to arrays - arrays work (sort of) like const pointers in this respect. What you can do though is copy a new value into the array:

strcpy(p.name, "Jane");

Char arrays are fine to use if you know the maximum size of the string in advance, e.g. in the first example you are 100% sure that the name will fit into 19 characters (not 20 because one character is always needed to store the terminating zero value).

Conversely, pointers are better if you don't know the possible maximum size of your string, and/or you want to optimize your memory usage, e.g. avoid reserving 512 characters for the name "John". However, with pointers you need to dynamically allocate the buffer they point to, and free it when not needed anymore, to avoid memory leaks.

Update: example of dynamically allocated buffers (using the struct definition in your 2nd example):

char* firstName = "Johnnie";
char* surname = "B. Goode";
person p;

p.name = malloc(strlen(firstName) + 1);
p.surname = malloc(strlen(surname) + 1);

p.age = 25;
strcpy(p.name, firstName);
strcpy(p.surname, surname);

printf("Name: %s; Age: %d\n",p.name,p.age);

free(p.surname);
free(p.name);

In your top level build.gradle you seem to have the code

android {
   compileSdkVersion 19
   buildToolsVersion "19.1" 
}

You can't have this code at the top level build.gradle because the android build plugin isn't loaded just yet. You can define the compile version and build tools version in the app level build.gradle.

Simplest way for create SSL certificate

Open Firefox (I suppose it's also possible with Chrome, but it's easier for me with FF)

Visit your development site with a self-signed SSL certificate.

Click on the certificate (next to the site name)

Click on "More information"

Click on "View certificate"

Click on "Details"

Click on "Export..."

Choose "X.509 Certificate whith chain (PEM)", select the folder and name to save it and click "Save"

Go to command line, to the directory where you downloaded the pem file and execute "openssl x509 -inform PEM -outform DM -in .pem -out .crt"

Copy the .crt file to the root of the /sdcard folder inside your Android device Inside your Android device, Settings > Security > Install from storage.

It should detect the certificate and let you add it to the device Browse to your development site.

The first time it should ask you to confirm the security exception. That's all.

The certificate should work with any browser installed on your Android (Browser, Chrome, Opera, Dolphin...)

Remember that if you're serving your static files from a different domain (we all are page speed bitches) you also need to add the certificate for that domain.

In TortoiseSVN, you can also Shift + right-click to get a menu that includes "Delete (keep local)".

If you're pulling dynamic records it's better to have 1 php file that creates a json representation and not create a file each time.

my_json.php

$array = array(
    'title' => $title,
    'url' => $url
);

echo stripslashes(json_encode($array)); 

Then in your script set the path to the file my_json.php

Create a toolbar in your xml...toolbar.xml:

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"

    </android.support.v7.widget.Toolbar>

Then add the following in your toolbar.xml:

app:titleTextColor="@color/colorText"
app:title="@string/app_name">

Remeber @color/colorText is simply your color.xml file with the color attribute named colorText and your color.This is the best way to calll your strings rather than hardcoding your color inside your toolbar.xml. You also have other options to modify your text,such as:textAppearance...etc...just type app:text...and intelisense will give you options in android studio.

your final toolbar should look like this:

 <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:layout_weight="1"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/Theme.AppCompat"
       app:subtitleTextAppearance="@drawable/icon"
        app:title="@string/app_name">
    </android.support.v7.widget.Toolbar>

NB:This toolbar should be inside your activity_main.xml.Easy Peasie

Another option is to do it all in your class:

Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setTitleTextColor(Color.WHITE);

Good Luck

In my case, it was giving me the error: Port 8005 required by Tomcat v8.0 Server at localhost is already in use

I changed 8005 port in apache-tomcat-8.0.39\conf\server.xml but changes were not getting reflected. Then I did these changes from eclipse. by double clicking server and modifying the port from 8005 to 8006 and it works.

Before putting 8006 I checked in windows shell if this port is available or not. By executing following command:

netstat -a -o -n | findstr 8006

However, avpicture_get_size is defined.

No, as the header (<libavcodec/avcodec.h>) just declares it.

The definition is in the library itself.

So you might like to add the linker option to link libavcodec when invoking gcc:

-lavcodec

Please also note that libraries need to be specified on the command line after the files needing them:

gcc -I$HOME/ffmpeg/include program.c -lavcodec

Not like this:

gcc -lavcodec -I$HOME/ffmpeg/include program.c

Referring to Wyzard's comment, the complete command might look like this:

gcc -I$HOME/ffmpeg/include program.c -L$HOME/ffmpeg/lib -lavcodec

For libraries not stored in the linkers standard location the option -L specifies an additional search path to lookup libraries specified using the -l option, that is libavcodec.x.y.z in this case.

For a detailed reference on GCC's linker option, please read here.

If the class that is implementing the interface is an abstract class, @Override is useful to ensure that the implementation is for an interface method; without the @Override an abstract class would just compile fine even if the implementation method signature does not match the method declared in the interface; the mismatched interface method would remain as unimplemented. The Java doc cited by @Zhao

The method does override or implement a method declared in a supertype

is clearly referring to an abstract super class; an interface can not be called the supertype. So, @Override is redundant and not sensible for interface method implementations in concrete classes.

There is a very nice and cool way to make a background image work like an img element so it adjust its height automatically. You need to know the image width and height ratio. Set the height of the container to 0 and set the padding-top as percentage based upon the image ratio.

It will look like the following:

div {
    background-image: url('http://www.pets4homes.co.uk/images/articles/1111/large/feline-influenza-all-about-cat-flu-5239fffd61ddf.jpg');
    background-size: contain;
    background-repeat: no-repeat;
    width: 100%;
    height: 0;
    padding-top: 66.64%; /* (img-height / img-width * container-width) */
                /* (853 / 1280 * 100) */
}

You just got a background image with auto height which will work just like an img element. Here is a working prototype (you can resize and check the div height): http://jsfiddle.net/TPEFn/2/

Or place the image in a location relative to a class and you don't need all that package/path info in the string itself.

com.xyz.SomeClassInThisPackage.class.getResource( "resources/camera.png" );

That way if you move the class to a different package, you dont have to find all the strings, you just move the class and its resources directory.

I noticed something perhaps relevant.

I had two scripts running, both doing rather slow queries. One of them locked a table and the other had to wait. The one that was waiting had default_socket_timeout = 300. Eventually it quit with "MySQL server has gone away". However, the mysql process list continued to show both query, the slow one still running and the other locked and waiting.

So I don't think mysqld is the culprit. Something has changed in the php mysql client. Quite possibly the default_socket_timeout which I will now set to -1 to see if that changes anything.

You have to create either another page or generic handler with the code to generate your pdf. Then that event gets triggered and the person is redirected to that page.

In my case i was using jQuery validation rules with

submitHandler function and submitting the data as new FormData(form);

Select Option

<select class="selectpicker" id="branch" name="branch" multiple="multiple" title="Of Branch" data-size="6" required>
  <option disabled>Multiple Branch Select</option>
  <option value="Computer">Computer</option>
  <option value="Civil">Civil</option>
  <option value="EXTC">EXTC</option>
  <option value="ETRX">ETRX</option>
  <option value="Mechinical">Mechinical</option>
</select>

<input type="hidden" name="new_branch" id="new_branch">

Get the multiple selected value and set to new_branch input value & while submitting the form get value from new_branch

Just replace hidden with text to view on the output

<input type="text" name="new_branch" id="new_branch">

Script (jQuery / Ajax)

<script>
    $(document).ready(function() {

      $('#branch').on('change', function(){
          var selected = $(this).find("option:selected"); //get current selected value
          var arrSelected = []; //Array to store your multiple value in stack
          selected.each(function(){
            arrSelected.push($(this).val()); //Stack the value
          });
          $('#new_branch').val(arrSelected); //It will set the multiple selected value to input new_branch
      });

    });
</script>

Among all the standard hash schemes, LDAP ssha is the most secure one to use,

You need to store the salt in your database as you suggested.

Yes you can.

You don't have to download both Anaconda.

Only you need to download one of the version of Anaconda and need activate other version of Anaconda python.

If you have Python 3, you can set up a Python 2 kernel like this;

python2 -m pip install ipykernel

python2 -m ipykernel install --user

If you have Python 2,

python3 -m pip install ipykernel

python3 -m ipykernel install --user

Then you will be able to see both version of Python!

If you are using Anaconda Spyder then you should swap version here:

If you are using Jupiter then check here:

Note: If your Jupiter or Anaconda already open after installation you need to restart again. Then you will be able to see.

Just look up the files you deleted, inside Recycle Bin. Right click on it and do restore as you do normally with other deleted files. It is similar as you do normally because VS code also uses normal trash of your system.

I think the biggest confusion is that xml namespace is pointing to some kind of URL that doesn't have any information. But the truth is that the person who invented below namespace:

xmlns:android="http://schemas.android.com/apk/res/android"

could also call it like that:

xmlns:android="asjkl;fhgaslifujhaslkfjhliuqwhrqwjlrknqwljk.rho;il"

This is just a unique identifier. However it is established that you should put there URL that is unique and can potentially point to the specification of used tags/attributes in that namespace. It's not required tho.

Why it should be unique? Because namespaces purpose is to have them unique so the attribute for example called background from your namespace can be distinguished from the background from another namespace.

Because of that uniqueness you do not need to worry that if you create your custom attribute you gonna have name collision.

install the dependencies:

npm install jquery --save
npm install tether --save
npm install bootstrap@version --save;

next, add scripts in your angular-cli.json

"scripts": [
        "../node_modules/jquery/dist/jquery.min.js",
        "../node_modules/tether/dist/js/tether.js",
        "../node_modules/bootstrap/dist/js/bootstrap.min.js",
        "script.js"
    ]

then, create a script.js

$("[data-toggle=tooltip]").tooltip();

now restart your server.

The line

when(someObject.doSomething(argumentCaptor.capture())).thenReturn(true);

would do the same as

when(someObject.doSomething(Matchers.any())).thenReturn(true);

So, using argumentCaptor.capture() when stubbing has no added value. Using Matchers.any() shows better what really happens and therefor is better for readability. With argumentCaptor.capture(), you can't read what arguments are really matched. And instead of using any(), you can use more specific matchers when you have more information (class of the expected argument), to improve your test.

And another problem: If using argumentCaptor.capture() when stubbing it becomes unclear how many values you should expect to be captured after verification. We want to capture a value during verification, not during stubbing because at that point there is no value to capture yet. So what does the argument captors capture method capture during stubbing? It capture anything because there is nothing to be captured yet. I consider it to be undefined behavior and I don't want to use undefined behavior.

How about some simple testing? Used the code below:

long start = System.currentTimeMillis();

String a = "a";

String b = "b";

for (int i = 0; i < 10000000; i++) { //ten million times
     String c = a.concat(b);
}

long end = System.currentTimeMillis();

System.out.println(end - start);

• The "a + b" version executed in 2500ms.
• The a.concat(b) executed in 1200ms.

Tested several times. The concat() version execution took half of the time on average.

This result surprised me because the concat() method always creates a new string (it returns a "new String(result)". It's well known that:

String a = new String("a") // more than 20 times slower than String a = "a"

Why wasn't the compiler capable of optimize the string creation in "a + b" code, knowing the it always resulted in the same string? It could avoid a new string creation. If you don't believe the statement above, test for your self.

Note from 2017: File::Slurp is not recommended due to design mistakes and unmaintained errors. Use File::Slurper or Path::Tiny instead.

extending on your answer

use File::Slurp ();
my $value = File::Slurp::slurp($filename);
$value =~ s/\R*//g;

File::Slurp abstracts away the File IO stuff and just returns a string for you.

NOTE

1. Important to note the addition of /g , without it, given a multi-line string, it will only replace the first offending character.

2. Also, the removal of $, which is redundant for this purpose, as we want to strip all line breaks, not just line-breaks before whatever is meant by $ on this OS.

3. In a multi-line string, $ matches the end of the string and that would be problematic ).

4. Point 3 means that point 2 is made with the assumption that you'd also want to use /m otherwise '$' would be basically meaningless for anything practical in a string with >1 lines, or, doing single line processing, an OS which actually understands $ and manages to find the \R* that proceed the $

Examples

while( my $line = <$foo> ){
      $line =~ $regex;
}

Given the above notation, an OS which does not understand whatever your files '\n' or '\r' delimiters, in the default scenario with the OS's default delimiter set for $/ will result in reading your whole file as one contiguous string ( unless your string has the $OS's delimiters in it, where it will delimit by that )

So in this case all of these regex are useless:

• /\R*$// : Will only erase the last sequence of \R in the file
• /\R*// : Will only erase the first sequence of \R in the file

• /\012?\015?// : When will only erase the first 012\015 , \012 , or \015 sequence, \015\012 will result in either \012 or \015 being emitted.

• /\R*$// : If there happens to be no byte sequences of '\015$OSDELIMITER' in the file, then then NO linebreaks will be removed except for the OS's own ones.

It would appear nobody gets what I'm talking about, so here is example code, that is tested to NOT remove line feeds. Run it, you'll see that it leaves the linefeeds in.

#!/usr/bin/perl

        print $fh join "", map { chr( int( rand(26) + 60 ) ) } 0 .. 20;
        print $fh "{1}";
        print $fh $lineDelimiter->();
        print $fh "{2}";
    }
    close $fh;
}

sub parse { 
    my $filename = shift;
    my $osDelimiter = shift;
    my $message = shift;
    print "Parsing $message File $filename : \n";

    local $/ = $osDelimiter;

    open my $fh, '<', $filename;
    while ( my $line = <$fh> )
    {

        $line =~ s/\R*$//;
        print ">|" . $line . "|<";

    }
    print "Done.\n\n";
}


my @all = ( $DOSNL,$MacNL,$UnixNL);
generate 'Windows.txt' , sub { $DOSNL }; 
generate 'Mac.txt' , sub { $MacNL };
generate 'Unix.txt', sub { $UnixNL };
generate 'Mixed.txt', sub {
    return @all[ int(rand(2)) ];
};


for my $os ( ["$MacNL", "On Mac"], ["$DOSNL", "On Windows"], ["$UnixNL", "On Unix"]){
    for ( qw( Windows Mac Unix Mixed ) ){
        parse $_ . ".txt", @{ $os };
    }
}

Note there are certain combinations that of course work, but they are likely the ones you yourself naívely tested.

Note that in this output, all results must be of the form >|$string|<>|$string|< with NO LINE FEEDS to be considered valid output.

You will need to get the textbox via javascript when moving the mouse over it and change its type to text. And when moving it out, you will want to change it back to password. No chance of doing this in pure CSS.

HTML:

<input type="password" name="password" id="myPassword" size="30" />
<img src="theicon" onmouseover="mouseoverPass();" onmouseout="mouseoutPass();" />

JS:

function mouseoverPass(obj) {
  var obj = document.getElementById('myPassword');
  obj.type = "text";
}
function mouseoutPass(obj) {
  var obj = document.getElementById('myPassword');
  obj.type = "password";
}

Try the display max_columns setting as follows:

import pandas as pd
from IPython.display import display

df = pd.read_csv("some_data.csv")
pd.options.display.max_columns = None
display(df)

Or

pd.set_option('display.max_columns', None)

Edit: Pandas 0.11.0 backwards

This is deprecated but in versions of Pandas older than 0.11.0 the max_columns setting is specified as follows:

pd.set_printoptions(max_columns=500)

The provided solution here is correct. However, the same error can also occur from a user error, where your endpoint request method is NOT matching the method your using when making the request.

If you have a readonly text box, could you not not make it a label and set AutoEllipsis=true?

alternatively there are posts with code for generating the autoellipsis yourself: (this does it for a grid, you would need to pass i the width for the text box instead. It isn't quite right as it hacks off a bit more than is necessary, and I haven;t got around to finding where the calculation is incorrect. it would be easy enough to modify to remove the first part of the directory rather than the last if you desire.

Private Function AddEllipsisPath(ByVal text As String, ByVal colIndex As Integer, ByVal grid As DataGridView) As String
    'Get the size with the column's width 
    Dim colWidth As Integer = grid.Columns(colIndex).Width

    'Calculate the dimensions of the text with the current font
    Dim textSize As SizeF = MeasureString(text, grid.Font)

    Dim rawText As String = text
    Dim FileNameLen As Integer = text.Length - text.LastIndexOf("\")
    Dim ReplaceWith As String = "\..."

    Do While textSize.Width > colWidth
        ' Trim to make room for the ellipsis
        Dim LastFolder As Integer = rawText.LastIndexOf("\", rawText.Length - FileNameLen - 1)

        If LastFolder < 0 Then
            Exit Do
        End If

        rawText = rawText.Substring(0, LastFolder) + ReplaceWith + rawText.Substring(rawText.Length - FileNameLen)

        If ReplaceWith.Length > 0 Then
            FileNameLen += 4
            ReplaceWith = ""
        End If
        textSize = MeasureString(rawText, grid.Font)
    Loop

    Return rawText
End Function

Private Function MeasureString(ByVal text As String, ByVal fontInfo As Font) As SizeF
    Dim size As SizeF
    Dim emSize As Single = fontInfo.Size
    If emSize = 0 Then emSize = 12

    Dim stringFont As New Font(fontInfo.Name, emSize)

    Dim bmp As New Bitmap(1000, 100)
    Dim g As Graphics = Graphics.FromImage(bmp)

    size = g.MeasureString(text, stringFont)
    g.Dispose()
    Return size
End Function

when slicing an array;

ls[y:x]  

takes the slice from element y upto and but not including x. when you use the negative indexing it is equivalent to using

ls[y:-1] == ls[y:len(ls)-1]

so it so the slice would be upto the last element, but it wouldn't include it (as per the slice)

For me, I usually use DataContext together in order to bind two-depth property such as this question.

<TextBlock DataContext="{Binding SelectedRule}" Text="{Binding Name}" />

Or, I prefer to use ElementName because it achieves bindings only with view controls.

<TextBlock DataContext="{Binding ElementName=lbRules, Path=SelectedItem}" Text="{Binding Name}" />

multiprocessing is not like threading. Each child process will get a copy of the main process's memory. Generally state is shared via communication (pipes/sockets), signals, or shared memory.

Multiprocessing makes some abstractions available for your use case - shared state that's treated as local by use of proxies or shared memory: http://docs.python.org/library/multiprocessing.html#sharing-state-between-processes

Relevant sections:

• http://docs.python.org/library/multiprocessing.html#shared-ctypes-objects

pygame.key.get_pressed() returns a list with the state of each key. If a key is held down, the state for the key is True, otherwise False. Use pygame.key.get_pressed() to evaluate the current state of a button and get continuous movement:

while True:

    pressed_key= pygame.key.get_pressed()
    x += (keys[pygame.K_RIGHT] - keys[pygame.K_LEFT]) * speed
    y += (keys[pygame.K_DOWN] - keys[pygame.K_UP]) * speed

The keyboard events (see pygame.event module) occur only once when the state of a key changes. The KEYDOWN event occurs once every time a key is pressed. KEYUP occurs once every time a key is released. Use the keyboard events for a single action or movement:

while True:

    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                x -= speed
            if event.key == pygame.K_RIGHT:
                x += speed
            if event.key == pygame.K_UP:
                y -= speed
            if event.key == pygame.K_DOWN:
                y += speed

        window.blit(bullet_surf, bullet_surf.get_rect(center = bullet_pos))
    pygame.display.flip()

pygame.quit()
exit()

This will definitely work............
You have to just replace your <ScrollView ></ScrollView> in layout XML file with this Custom ScrollView like <com.tmd.utils.VerticalScrollview > </com.tmd.utils.VerticalScrollview >

package com.tmd.utils;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.ScrollView;

public class VerticalScrollview extends ScrollView{

    public VerticalScrollview(Context context) {
        super(context);
    }

     public VerticalScrollview(Context context, AttributeSet attrs) {
            super(context, attrs);
        }

        public VerticalScrollview(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);
        }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        final int action = ev.getAction();
        switch (action)
        {
            case MotionEvent.ACTION_DOWN:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: DOWN super false" );
                    super.onTouchEvent(ev);
                    break;

            case MotionEvent.ACTION_MOVE:
                    return false; // redirect MotionEvents to ourself

            case MotionEvent.ACTION_CANCEL:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: CANCEL super false" );
                    super.onTouchEvent(ev);
                    break;

            case MotionEvent.ACTION_UP:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: UP super false" );
                    return false;

            default: Log.i("VerticalScrollview", "onInterceptTouchEvent: " + action ); break;
        }

        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        super.onTouchEvent(ev);
        Log.i("VerticalScrollview", "onTouchEvent. action: " + ev.getAction() );
         return true;
    }
}

No, it doesn't uninstall the dependencies packages. It only removes the specified package:

$ pip install specloud
$ pip freeze # all the packages here are dependencies of specloud package

figleaf==0.6.1
nose==1.1.2
pinocchio==0.3
specloud==0.4.5

$ pip uninstall specloud
$ pip freeze

figleaf==0.6.1
nose==1.1.2
pinocchio==0.3

As you can see those packages are dependencies from specloud and they're still there, but not the specloud package itself.

As mentioned below, You can install and use the pip-autoremove utility to remove a package plus unused dependencies.

use:

String[] mStrings = new String[title.length];

Microsoft do not support C99 and haven't announced any plans to. I believe they intend to track C++ standards but consider C as effectively obsolete except as a subset of C++.

New projects in Visual Studio 2003 and later have the "Compile as C++ Code (/TP)" option set by default, so any .c files will be compiled as C++.

1. PSYoungGen refers to the garbage collector in use for the minor collection. PS stands for Parallel Scavenge.
2. The first set of numbers are the before/after sizes of the young generation and the second set are for the entire heap. (Diagnosing a Garbage Collection problem details the format)
3. The name indicates the generation and collector in question, the second set are for the entire heap.

An example of an associated full GC also shows the collectors used for the old and permanent generations:

3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)] 
            [ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K) 
            [PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]

Finally, breaking down one line of your example log output:

8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]

• 107Mb used before GC, 14Mb used after GC, max young generation size 137Mb
• 675Mb heap used before GC, 581Mb heap used after GC, 1Gb max heap size
• minor GC occurred 8109.128 seconds since the start of the JVM and took 0.04 seconds

If you have enabled Developer Options and USB Debugging for a Nexus, the win-usb supposedly works.

One tell-tale sign whether your driver is right is if it's got ADB in the name in Device Manager.

For my Galaxy line, I had a driver installed, but it wasn't the ADB driver.

For many non-Nexus Androids, the win-usb driver will not work. Instead, you will need to install one of the OEM drivers: https://developer.android.com/studio/run/oem-usb.html

This finally got me an ADB compatible driver, and after switching to PTP adb finally was able to find my device.

There is a built-in method to get the bounding rectangle: Element.getBoundingClientRect.

The result is the smallest rectangle which contains the entire element, with the read-only left, top, right, bottom, x, y, width, and height properties.

See the example below:

let innerBox = document.getElementById("myDiv").getBoundingClientRect().height;_x000D_
document.getElementById("data_box").innerHTML = "height: " + innerBox;

body {_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.relative {_x000D_
  width: 220px;_x000D_
  height: 180px;_x000D_
  position: relative;_x000D_
  background-color: purple;_x000D_
}_x000D_
_x000D_
.absolute {_x000D_
  position: absolute;_x000D_
  top: 30px;_x000D_
  left: 20px;_x000D_
  background-color: orange;_x000D_
  padding: 30px;_x000D_
  overflow: hidden;_x000D_
}_x000D_

you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:

#!/bin/sh

OPTIONS=$(getopt -o hf:gb -l help,file:,foo,bar -- "$@")

if [ $? -ne 0 ]; then
  echo "getopt error"
  exit 1
fi

eval set -- $OPTIONS

while true; do
  case "$1" in
    -h|--help) HELP=1 ;;
    -f|--file) FILE="$2" ; shift ;;
    -g|--foo)  FOO=1 ;;
    -b|--bar)  BAR=1 ;;
    --)        shift ; break ;;
    *)         echo "unknown option: $1" ; exit 1 ;;
  esac
  shift
done

if [ $# -ne 0 ]; then
  echo "unknown option(s): $@"
  exit 1
fi

echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"

see also:

• the "canonical" example: http://software.frodo.looijaard.name/getopt/docs/getopt-parse.bash
• a blog post: http://www.missiondata.com/blog/system-administration/17/17/
• man getopt

It's missing an 'int'. It should be:

const static int foo = 42;

In C and C++, it declares an integer constant with local file scope of value 42.

Why 42? If you don't already know (and it's hard to believe you don't), it's a refernce to the Answer to Life, the Universe, and Everything.

You need to import @angular/forms dependency to your module.

if you are using npm, install the dependency :

npm install @angular/forms --save

Import it to your module :

import {FormsModule} from '@angular/forms';
@NgModule({
    imports: [.., FormsModule,..],
    declarations: [......],
    bootstrap: [......]
})

And if you are using SystemJs for loading modules

'@angular/forms': 'node_modules/@angular/forms/bundles/forms.umd.js',

Now you can use [(ngModel)] for two ways databinding.

In addition to @Jon Skeet's answer:

Traditionally Windows has used \r\n, Unix \n and Mac \r, however newer Macs use \n as they're unix based.

I had the same problem (changing a parameter from the HTTP request in the Filter). I ended up by using a ThreadLocal<String>. In the Filter I have:

class MyFilter extends Filter {
    public static final ThreadLocal<String> THREAD_VARIABLE = new ThreadLocal<>();
    public void doFilter(HttpServletRequest request, HttpServletResponse response, FilterChain chain) {
        THREAD_VARIABLE.set("myVariableValue");
        chain.doFilter(request, response);
    }
}

In my request processor (HttpServlet, JSF controller or any other HTTP request processor), I get the current thread value back:

...
String myVariable = MyFilter.THREAD_VARIABLE.get();
...

Advantages:

• more versatile than passing HTTP parameters (you can pass POJO objects)
• slightly faster (no need to parse the URL to extract the variable value)
• more elegant thant the HttpServletRequestWrapper boilerplate
• the variable scope is wider than just the HTTP request (the scope you have when doing request.setAttribute(String,Object), i.e. you can access the variable in other filtrers.

Disadvantages:

• You can use this method only when the thread which process the filter is the same as the one which process the HTTP request (this is the case in all Java-based servers I know). Consequently, this will not work when
  • doing a HTTP redirect (because the browser does a new HTTP request and there is no way to guarantee that it will be processed by the same thread)
  • processing data in separate threads, e.g. when using java.util.stream.Stream.parallel, java.util.concurrent.Future, java.lang.Thread.
• You must be able to modify the request processor/application

Some side notes:

• The server has a Thread pool to process the HTTP requests. Since this is pool:

  1. a Thread from this thread pool will process many HTTP requests, but only one at a time (so you need either to cleanup you variable after usage or to define it for each HTTP request = pay attention to code such as if (value!=null) { THREAD_VARIABLE.set(value);} because you will reuse the value from the previous HTTP request when value is null : side effects are guaranteed).
  2. There is no guarantee that two requests will be processed by the same thread (it may be the case but you have no guarantee). If you need to keep user data from one request to another request, it would be better to use HttpSession.setAttribute()
• The JEE @RequestScoped internally uses a ThreadLocal, but using the ThreadLocal is more versatile: you can use it in non JEE/CDI containers (e.g. in multithreaded JRE applications)

Just addition to above answers ..

[FromUri] can also be used to bind complex types from uri parameters instead of passing parameters from querystring

For Ex..

public class GeoPoint
{
    public double Latitude { get; set; } 
    public double Longitude { get; set; }
}

[RoutePrefix("api/Values")]
public ValuesController : ApiController
{
    [Route("{Latitude}/{Longitude}")]
    public HttpResponseMessage Get([FromUri] GeoPoint location) { ... }
}

Can be called like:

http://localhost/api/values/47.678558/-122.130989

first import os module in your app than with use from getpid function get pid's app and save in a file.for example :

import os
pid = os.getpid()
op = open("/var/us.pid","w")
op.write("%s" % pid)
op.close()

and create a bash file in /etc/init.d path: /etc/init.d/servername

PATHAPP="/etc/bin/userscript.py &"
PIDAPP="/var/us.pid"
case $1 in 
        start)
                echo "starting"
                $(python $PATHAPP)
        ;;
        stop)
                echo "stoping"
                PID=$(cat $PIDAPP)
                kill $PID
        ;;

esac

now , u can start and stop ur app with down command:

service servername stop service servername start

or

/etc/init.d/servername stop /etc/init.d/servername start

You can also chain commands if you use the '!' operator to spawn a shell:

aa = !git add -A && git status

This will both add all files and give you a status report with $ git aa.

For a handy way to check your aliases, add this alias:

alias = config --get-regexp ^alias\\.

Then a quick $ git alias gives you your current aliases and what they do.

You can also make use of FilesystemIterator. It requires even less code then DirectoryIterator, and automatically removes . and ...

// Let's traverse the images directory
$fileSystemIterator = new FilesystemIterator('images');

$entries = array();
foreach ($fileSystemIterator as $fileInfo){
    $entries[] = $fileInfo->getFilename();
}

var_dump($entries);

//OUTPUT
object(FilesystemIterator)[1]

array (size=14)
  0 => string 'aa[1].jpg' (length=9)
  1 => string 'Chrysanthemum.jpg' (length=17)
  2 => string 'Desert.jpg' (length=10)
  3 => string 'giphy_billclinton_sad.gif' (length=25)
  4 => string 'giphy_shut_your.gif' (length=19)
  5 => string 'Hydrangeas.jpg' (length=14)
  6 => string 'Jellyfish.jpg' (length=13)
  7 => string 'Koala.jpg' (length=9)
  8 => string 'Lighthouse.jpg' (length=14)
  9 => string 'Penguins.jpg' (length=12)
  10 => string 'pnggrad16rgb.png' (length=16)
  11 => string 'pnggrad16rgba.png' (length=17)
  12 => string 'pnggradHDrgba.png' (length=17)

I suffered from this issue a lot when using dynamic resource allocation. I had thought it would utilize my cluster resources to best fit the application.

But the truth is the dynamic resource allocation doesn't set the driver memory and keeps it to its default value, which is 1G.

I resolved this issue by setting spark.driver.memory to a number that suits my driver's memory (for 32GB ram I set it to 18G).

You can set it using spark submit command as follows:

spark-submit --conf spark.driver.memory=18g

Very important note, this property will not be taken into consideration if you set it from code, according to Spark Documentation - Dynamically Loading Spark Properties:

Spark properties mainly can be divided into two kinds: one is related to deploy, like “spark.driver.memory”, “spark.executor.instances”, this kind of properties may not be affected when setting programmatically through SparkConf in runtime, or the behavior is depending on which cluster manager and deploy mode you choose, so it would be suggested to set through configuration file or spark-submit command line options; another is mainly related to Spark runtime control, like “spark.task.maxFailures”, this kind of properties can be set in either way.

If you're unsure about something, try writing a test first.

I did this:

class ClassNameTest {
    public static void main(final String... arguments) {
        printNamesForClass(
            int.class,
            "int.class (primitive)");
        printNamesForClass(
            String.class,
            "String.class (ordinary class)");
        printNamesForClass(
            java.util.HashMap.SimpleEntry.class,
            "java.util.HashMap.SimpleEntry.class (nested class)");
        printNamesForClass(
            new java.io.Serializable(){}.getClass(),
            "new java.io.Serializable(){}.getClass() (anonymous inner class)");
    }

    private static void printNamesForClass(final Class<?> clazz, final String label) {
        System.out.println(label + ":");
        System.out.println("    getName():          " + clazz.getName());
        System.out.println("    getCanonicalName(): " + clazz.getCanonicalName());
        System.out.println("    getSimpleName():    " + clazz.getSimpleName());
        System.out.println("    getTypeName():      " + clazz.getTypeName()); // added in Java 8
        System.out.println();
    }
}

Prints:

int.class (primitive):
    getName():          int
    getCanonicalName(): int
    getSimpleName():    int
    getTypeName():      int

String.class (ordinary class):
    getName():          java.lang.String
    getCanonicalName(): java.lang.String
    getSimpleName():    String
    getTypeName():      java.lang.String

java.util.HashMap.SimpleEntry.class (nested class):
    getName():          java.util.AbstractMap$SimpleEntry
    getCanonicalName(): java.util.AbstractMap.SimpleEntry
    getSimpleName():    SimpleEntry
    getTypeName():      java.util.AbstractMap$SimpleEntry

new java.io.Serializable(){}.getClass() (anonymous inner class):
    getName():          ClassNameTest$1
    getCanonicalName(): null
    getSimpleName():    
    getTypeName():      ClassNameTest$1

There's an empty entry in the last block where getSimpleName returns an empty string.

The upshot looking at this is:

• the name is the name that you'd use to dynamically load the class with, for example, a call to Class.forName with the default ClassLoader. Within the scope of a certain ClassLoader, all classes have unique names.
• the canonical name is the name that would be used in an import statement. It might be useful during toString or logging operations. When the javac compiler has complete view of a classpath, it enforces uniqueness of canonical names within it by clashing fully qualified class and package names at compile time. However JVMs must accept such name clashes, and thus canonical names do not uniquely identify classes within a ClassLoader. (In hindsight, a better name for this getter would have been getJavaName; but this method dates from a time when the JVM was used solely to run Java programs.)
• the simple name loosely identifies the class, again might be useful during toString or logging operations but is not guaranteed to be unique.
• the type name returns "an informative string for the name of this type", "It's like toString: it's purely informative and has no contract value". (as written by sir4ur0n)

You can redirect by using the header() function to modify the Location header.

$.each() works for objects and arrays both:

var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };

$.each(data.programs, function (i) {
    $.each(data.programs[i], function (key, val) {
        alert(key + val);
    });
});

...and since you will get the current array element as second argument:

$.each(data.programs, function (i, currProgram) {
    $.each(currProgram, function (key, val) {
        alert(key + val);
    });
});

As stated above, many languages are available for developing in Android. Java, C, Scala, C++, several scripting languages etc. Thanks to Mono you are also able to develop using C# and the .Net framework. Here you have some speedcomparisions: http://www.youtube.com/watch?v=It8xPqkKxis

Do you have times associated with your dates? BETWEEN is inclusive, but when you convert 2013-10-18 to a date it becomes 2013-10-18 00:00:000.00. Anything that is logged after the first second of the 18th will not shown using BETWEEN, unless you include a time value.

Try:

SELECT * FROM LOGS WHERE CHECK_IN BETWEEN CONVERT(datetime,'2013-10-17') AND CONVERT(datetime,'2013-10-18 23:59:59:999')

if you want to search the entire day of the 18th.

SQL DATETIME fields have milliseconds. So I added 999 to the field.

Sometimes, you need to list the variables of an object and not for debugging purposes. The right way to do it is using get_object_vars($object). It returns an array that has all the class variables and their value. You can then loop through them in a foreach loop. If used within the object itself, simply do get_object_vars($this)

You can do it with a LIMIT, just not with a LIMIT and an OFFSET.

 How can I remove duplicate elements from a list or array?
   (contributed by brian d foy)

   Use a hash. When you think the words "unique" or "duplicated", think
   "hash keys".

   If you don't care about the order of the elements, you could just
   create the hash then extract the keys. It's not important how you
   create that hash: just that you use "keys" to get the unique elements.

       my %hash   = map { $_, 1 } @array;
       # or a hash slice: @hash{ @array } = ();
       # or a foreach: $hash{$_} = 1 foreach ( @array );

       my @unique = keys %hash;

   If you want to use a module, try the "uniq" function from
   "List::MoreUtils". In list context it returns the unique elements,
   preserving their order in the list. In scalar context, it returns the
   number of unique elements.

       use List::MoreUtils qw(uniq);

       my @unique = uniq( 1, 2, 3, 4, 4, 5, 6, 5, 7 ); # 1,2,3,4,5,6,7
       my $unique = uniq( 1, 2, 3, 4, 4, 5, 6, 5, 7 ); # 7

   You can also go through each element and skip the ones you've seen
   before. Use a hash to keep track. The first time the loop sees an
   element, that element has no key in %Seen. The "next" statement creates
   the key and immediately uses its value, which is "undef", so the loop
   continues to the "push" and increments the value for that key. The next
   time the loop sees that same element, its key exists in the hash and
   the value for that key is true (since it's not 0 or "undef"), so the
   next skips that iteration and the loop goes to the next element.

       my @unique = ();
       my %seen   = ();

       foreach my $elem ( @array )
       {
         next if $seen{ $elem }++;
         push @unique, $elem;
       }

   You can write this more briefly using a grep, which does the same
   thing.

       my %seen = ();
       my @unique = grep { ! $seen{ $_ }++ } @array;

You can do like here

var avatarImageView = UIImageView()
var imagePicker = UIImagePickerController()
        
func takePhotoFromGallery() {
    imagePicker.delegate = self
    imagePicker.sourceType = .savedPhotosAlbum
    imagePicker.allowsEditing = true
    
    present(imagePicker, animated: true)
}

func imagePickerController(_ picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let pickedImage = info[.originalImage] as? UIImage {
        avatarImageView.contentMode = .scaleAspectFill
        avatarImageView.image = pickedImage
    }
    self.dismiss(animated: true)
}

$department = mysql_real_escape_string($_POST['department']);
$name = mysql_real_escape_string($_POST['name']);
$email = mysql_real_escape_string($_POST['email']);
$message = mysql_real_escape_string($_POST['message']);

As is, it was looking for constants called department, name, email, message, etc. When it doesn't find such a constant, PHP (bizarrely) interprets it as a string ('department', etc). Obviously, this can easily break if you do defined such a constant later (though it's bad style to have lower-case constants).

This is a general error, which throws sometimes, when you have mismatch between the types of the data you use. E.g I tried to resize the image with opencv, it gave the same error. Here is a discussion about it.

I strongly advice NOT to use the code:

process.setMaxListeners(0);

The warning is not there without reason. Most of the time, it is because there is an error hidden in your code. Removing the limit removes the warning, but not its cause, and prevents you from being warned of a source of resource leakage.

If you hit the limit for a legitimate reason, put a reasonable value in the function (the default is 10).

Also, to change the default, it is not necessary to mess with the EventEmitter prototype. you can set the value of defaultMaxListeners attribute like so:

require('events').EventEmitter.defaultMaxListeners = 15;
