http://www.php-guru.in/2013/html-to-pdf-conversion-in-codeigniter/

Or you can see below

There are number of PHP libraries on the web to convert HTML page to PDF file. They are easy to implement and deploy when you are working on any web application in core PHP. But when we try to integrate this libraries with any framework or template, then it becomes very tedious work if the framework which we are using does not have its own library to integrate it with any PDF library. The same situation came in front of me when there was one requirement to convert HTML page to PDF file and the framework I was using was codeigniter.

I searched on web and got number of PHP libraries to convert HTML page to PDF file. After lot of research and googling I decided to go with TCPDF PHP library to convert HTML page to PDF file for my requirement. I found TCPDf PHP library quite easy to integrate with codeigniter and stated working on it. After successfully completing my integration of codeigniter and TCPDF, I thought of sharing this script on web.

Now, let’s start with implimentation of the code.

Download the TCPDF library code, you can download it from TCPDF website http://www.tcpdf.org/.

Now create “tcpdf” folder in “application/helpers/” directory of your web application which is developed in codeigniter. Copy all TCPDF library files and paste it in “application/helpers/tcpdf/” directory. Update the configuration file “tcpdf_config.php” of TCPDF, which is located in “application/helpers/tcpdf/config” directory, do changes according to your applicatoin requirements. We can set logo, font, font size, with, height, header etc in the cofing file. Give read, write permissions to “cache” folder which is there in tcpdf folder. After defining your directory structure, updating configuration file and assigning permissions, here starts your actual coding part.

Create one PHP helper file in “application/helpers/” directory of codeigniter, say “pdf_helper.php”, then copy below given code and paste it in helper file

Helper: application/helpers/pdf_helper.php

function tcpdf()
{
    require_once('tcpdf/config/lang/eng.php');
    require_once('tcpdf/tcpdf.php');
}

Then in controller file call the above helper, suppose our controller file is “createpdf.php” and it has method as pdf(), so the method pdf() will load the “pdf_helper” helper and will also have any other code.

Controller: application/controllers/createpdf.php

function pdf()
{
    $this->load->helper('pdf_helper');
    /*
        ---- ---- ---- ----
        your code here
        ---- ---- ---- ----
    */
    $this->load->view('pdfreport', $data);
}

Now create one view file, say “pdfreport.php” in “application/views/” directory, which is also loaded in pdf() method in controller. So in view file we can directly call the tcpdf() function which we have defined in “pdf_helper” helper, which will load all required TCPDF classes, functions, variable etc. Then we can directly use the TCPDF example codes as it is in our current controller or view. Now in out current view “pdfreport” copy the given code below:

View: application/views/pdfreport.php

tcpdf();
$obj_pdf = new TCPDF('P', PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$obj_pdf->SetCreator(PDF_CREATOR);
$title = "PDF Report";
$obj_pdf->SetTitle($title);
$obj_pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, $title, PDF_HEADER_STRING);
$obj_pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$obj_pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$obj_pdf->SetDefaultMonospacedFont('helvetica');
$obj_pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$obj_pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$obj_pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$obj_pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$obj_pdf->SetFont('helvetica', '', 9);
$obj_pdf->setFontSubsetting(false);
$obj_pdf->AddPage();
ob_start();
    // we can have any view part here like HTML, PHP etc
    $content = ob_get_contents();
ob_end_clean();
$obj_pdf->writeHTML($content, true, false, true, false, '');
$obj_pdf->Output('output.pdf', 'I');

Thus our HTML page will be converted to PDF using TCPDF in CodeIgniter. We can also embed images,css,modifications in PDF file by using TCPDF library.

As opposed to passing the text as a variable, you can use the DOM to retrieve the data in your function:

var text = document.getElementsByName("textbox1").value;

Angular CLI 1.x.x (Works with Angular 4.x.x, 5.x.x)

This supports:

• Angular 2.x and 4.x
• Latest Webpack 2.x
• Angular AoT compiler
• Routing (normal and lazy)
• SCSS
• Custom file bundling (assets)
• Additional development tools (linter, unit & end-to-end test setups)

Initial Setup

ng new project-name --routing

You can add --style=scss for SASS .scss support.

You can add --ng4 for using Angular 4 instead of Angular 2.

After creating the project, the CLI will automatically run npm install for you. If you want to use Yarn instead, or just want to look at the project skeleton without install, check how to do it here.

Bundle Steps

Inside the project folder:

ng build -prod

At the current version you need to to specify --aot manually, because it can be used in development mode (although that's not practical due to slowness).

This also performs AoT compilation for even smaller bundles (no Angular compiler, instead, generated compiler output). The bundles are much smaller with AoT if you use Angular 4 as the generated code is smaller.
You can test your app with AoT in development mode (sourcemaps, no minification) and AoT by running ng build --aot.

Output

The default output dir is ./dist, although it can be changed in ./angular-cli.json.

Deployable Files

The result of build step is the following:

(Note: <content-hash> refers to hash / fingerprint of the contents of the file that's meant to be a cache busting way, this is possible since Webpack writes the script tags by itself)

• ./dist/assets
  Files copied as-is from ./src/assets/**
• ./dist/index.html
  From ./src/index.html, after adding webpack scripts to it
  Source template file is configurable in ./angular-cli.json
• ./dist/inline.js
  Small webpack loader / polyfill
• ./dist/main.<content-hash>.bundle.js
  The main .js file containing all the .js scripts generated / imported
• ./dist/styles.<content-hash>.bundle.js
  When you use Webpack loaders for CSS, which is the CLI way, they are loaded via JS here

In older versions it also created gzipped versions for checking their size, and .map sourcemaps files, but this is no longer happening as people kept asking to remove these.

Other Files

In certain other occasions, you might find other unwanted files/folders:

• ./out-tsc/
  From ./src/tsconfig.json's outDir
• ./out-tsc-e2e/
  From ./e2e/tsconfig.json's outDir
• ./dist/ngfactory/
  From AoT compiler (not configurable without forking the CLI as of beta 16)

You can't update two tables at once, but you can link an update into an insert using OUTPUT INTO, and you can use this output as a join for the second update:

DECLARE @ids TABLE (id int);
BEGIN TRANSACTION

UPDATE Table1 
SET Table1.LastName = 'DR. XXXXXX'  
OUTPUT INSERTED.id INTO @ids
WHERE Table1.field = '010008';

UPDATE Table2 
SET Table2.WAprrs = 'start,stop' 
FROM Table2 
JOIN @ids i on i.id = Table2.id;

COMMIT;

I changed your example WHERE condition to be some other field than id. If it's id the you don't need this fancy OUTPUT, you can just UPDATE the second table for the same id='010008'.

You can use :

window.history.pushState('obj', 'newtitle', newUrlWithQueryString)

#Pure css method

Place this at the top of your code (before header tag)

<style> .loader {_x000D_

</style>

<div class="loader">_x000D_
  Your Content For Load Screen_x000D_

And This At The Bottom after all other code (except /html tag)

    }_x000D_
_x000D_
    to {_x000D_

        opacity: 0;_x000D_
    }_x000D_

This always works for me 100% of the time

Just for the sake of completeness, we can use the operators [ and [[:

set.seed(1)
df <- data.frame(v1 = runif(10), v2 = letters[1:10])

Several options

df[df[1] < 0.5 | df[2] == "g", ] 
df[df[[1]] < 0.5 | df[[2]] == "g", ] 
df[df["v1"] < 0.5 | df["v2"] == "g", ]

df$name is equivalent to df[["name", exact = FALSE]]

Using dplyr:

library(dplyr)
filter(df, v1 < 0.5 | v2 == "g")

Using sqldf:

library(sqldf)
sqldf('SELECT *
      FROM df 
      WHERE v1 < 0.5 OR v2 = "g"')

Output for the above options:

          v1 v2
1 0.26550866  a
2 0.37212390  b
3 0.20168193  e
4 0.94467527  g
5 0.06178627  j

You need the ip of the other pc and do:

scp user@ip_of_remote_pc:/home/user/stuff.php /Users/djorge/Desktop

it will ask you for 'user's password on the other pc.

The startup project that references the project where Entity Framework is being used needs the following two assemblies in it's bin folder:

• EntityFramework.dll
• EntityFramework.SqlServer.dll

Adding a <section> to the <configSections> of the .config file on the startup project makes the first assembly available in that bin directory. You can copy this from the .config file of your Entity Framework project:

<configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>

To make the second .dll available in the bin folder, although not practical, a manual copy from the bin folder of the Entity Framework project can be made. A better alternative is to add to the Post-Build Events of the Entity Framework project the following lines, which will automate the process:

cd $(ProjectDir)
xcopy /y bin\Debug\EntityFramework.SqlServer.dll ..\{PATH_TO_THE_PROJECT_THAT_NEEDS_THE_DLL}\bin\Debug\

A bit more elaborate version (to use from another window):

#!/bin/bash

DELAY=3

TERM_PID=$(echo `ps -C gnome-terminal -o pid= | head -1`) # get first gnome-terminal's PID
WID=$(wmctrl -lp | awk -v pid=$TERM_PID '$3==pid{print $1;exit;}') # get window id

xdotool windowfocus $WID
xdotool key alt+t # my key map
xdotool sleep $DELAY # it may take a while to start new shell :(
xdotool type --delay 1 --clearmodifiers "$@"
xdotool key Return

wmctrl -i -a $WID # go to that window (WID is numeric)

# vim:ai
# EOF #

Like so

DECLARE @t INT=1

SELECT CASE
            WHEN @t>0 THEN
                CASE
                    WHEN @t=1 THEN 'one'
                    ELSE 'not one'
                END
            ELSE 'less than one'
        END

EDIT: After looking more at the question, I think the best option is to create a function that calculates the value. That way, if you end up having multiple places where the calculation needs done, you only have one point to maintain the logic.

Try this, it worked for me.

div{_x000D_
  border-radius: 20px;_x000D_
  height: 70vh;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
div::before{_x000D_
  content: '';_x000D_
  display: block;_x000D_

In my situation, in order to include color.sh from the same directory in init.sh, I had to do something as follows.

. ./color.sh

Not sure why the ./ and not color.sh directly. The content of color.sh is as follows.

RED=`tput setaf 1`
GREEN=`tput setaf 2`
BLUE=`tput setaf 4`
BOLD=`tput bold`
RESET=`tput sgr0`

Making use of File color.sh does not error but, the color do not display. I have tested this in Ubuntu 18.04 and the Bash version is:

GNU bash, version 4.4.19(1)-release (x86_64-pc-linux-gnu)

1. Implement javax.servlet.Filter.
2. In doFilter() method, cast the incoming ServletRequest to HttpServletRequest.
3. Use HttpServletRequest#getRequestURI() to grab the path.
4. Use straightforward java.lang.String methods like substring(), split(), concat() and so on to extract the part of interest and compose the new path.
5. Use either ServletRequest#getRequestDispatcher() and then RequestDispatcher#forward() to forward the request/response to the new URL (server-side redirect, not reflected in browser address bar), or cast the incoming ServletResponse to HttpServletResponse and then HttpServletResponse#sendRedirect() to redirect the response to the new URL (client side redirect, reflected in browser address bar).
6. Register the filter in web.xml on an url-pattern of /* or /Check_License/*, depending on the context path, or if you're on Servlet 3.0 already, use the @WebFilter annotation for that instead.

Don't forget to add a check in the code if the URL needs to be changed and if not, then just call FilterChain#doFilter(), else it will call itself in an infinite loop.

Alternatively you can also just use an existing 3rd party API to do all the work for you, such as Tuckey's UrlRewriteFilter which can be configured the way as you would do with Apache's mod_rewrite.

Have you tried the classic, waiting for the load to complete using jQuery's builtin ready function?

$(document).ready(function() {
    $('some selector', frames['nameOfMyIframe'].document).doStuff()

For those still getting this error, adding encode("utf-8") to soup will also fix this.

soup = BeautifulSoup(html_doc, 'html.parser').encode("utf-8")
print(soup)

Maybe too many years late, but nevertheless a theory to try.

The ratio of bounding rectangle of red logo region to the overall dimension of the bottle/can is different. In the case of Can, should be 1:1, whereas will be different in that of bottle (with or without cap). This should make it easy to distinguish between the two.

Update: The horizontal curvature of the logo region will be different between the Can and Bottle due their respective size difference. This could be specifically useful if your robot needs to pick up can/bottle, and you decide the grip accordingly.

A shorter alternative to the first solution given by Russ Cam would be:

$('#mySelect').val('');

This assumes you want to retain the list, but make it so that no option is selected.

If you wish to select a particular default value, just pass that value instead of an empty string.

$('#mySelect').val('someDefaultValue');

or to do it by the index of the option, you could do:

$('#mySelect option:eq(0)').attr('selected','selected'); // Select first option

I have used

System.AppDomain.CurrentDomain.BaseDirectory

when I want to find a path relative to an applications folder. This works for both ASP.Net and winform applications. It also does not require any reference to System.Web assemblies.

Using file:///// just doesn't work if security settings are set to even a moderate level.

If you just want users to be able to download/view files* located on a network or share you can set up a Virtual Directory in IIS. On the Properties tab make sure the "A share located on another computer" is selected and the "Connect as..." is an account that can see the network location.

Link to the virtual directory from your webpage (e.g. http://yoursite/yourvirtualdir/) and this will open up a view of the directory in the web browser.

*You can allow write permissions on the virtual directory to allow users to add files but not tried it and assume network permissions would override this setting.

THIRD VERSION OF MY ANSWER:

Here's a multiple line example of inline Jade Javascript. I don't think you can write it without using a -. This is a flash message example that I use in a partial. Hope this helps!

-if(typeof(info) !== 'undefined')
  -if (info)
    - if(info.length){
      ul
        -info.forEach(function(info){
          li= info
      -})
  -}

Is the code you're trying to get to compile the code in your question?

If so, you don't need two things: first, you don't need to declare that it's Javascript/a script, you can just started coding after typing -; second, after you type -if you don't need to type the { or } either. That's what makes Jade pretty sweet.

--------------ORIGINAL ANSWER BELOW ---------------

Try prepending if with -:

-if(10 == 10)
  //do whatever you want here as long as it's indented two spaces from
   the `-` above

There are also tons of Jade examples at:

https://github.com/visionmedia/jade/blob/master/examples/

Depending on what exactly you are doing you could make an image and set it as the background programatically.

For me It happened after Mac OS update to Mojave and git was not functioning in Intellij

Solution:- Go to Settings, then File | Settings | Version Control | Git and edit Path to Git executable field which is /usr/local/bin/git

The other answers are very complete, and you should definitely use them if you're trying to find the last character of a string. But if you're just trying to use a conditional (e.g. is the last character 'g'), you could also do the following:

if (str.endsWith("g")) {

or, strings

if (str.endsWith("bar")) {

Here is a much faster version, which doesn't use regular expressions, nor encodeURIComponent():

function byteLength(str) {
  // returns the byte length of an utf8 string
  var s = str.length;
  for (var i=str.length-1; i>=0; i--) {
    var code = str.charCodeAt(i);
    if (code > 0x7f && code <= 0x7ff) s++;
    else if (code > 0x7ff && code <= 0xffff) s+=2;
    if (code >= 0xDC00 && code <= 0xDFFF) i--; //trail surrogate
  }
  return s;
}

Here is a performance comparison.

It just computes the length in UTF8 of each unicode codepoints returned by charCodeAt() (based on wikipedia's descriptions of UTF8, and UTF16 surrogate characters).

It follows RFC3629 (where UTF-8 characters are at most 4-bytes long).

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

run command creates a container from the image and then starts the root process on this container. Running it with run --rm flag would save you the trouble of removing the useless dead container afterward and would allow you to ignore the existence of docker start and docker remove altogether.

run command does a few different things:

docker run --name dname image_name bash -c "whoami"

1. Creates a Container from the image. At this point container would have an id, might have a name if one is given, will show up in docker ps
2. Starts/executes the root process of the container. In the code above that would execute bash -c "whoami". If one runs docker run --name dname image_name without a command to execute container would go into stopped state immediately.
3. Once the root process is finished, the container is stopped. At this point, it is pretty much useless. One can not execute anything anymore or resurrect the container. There are basically 2 ways out of stopped state: remove the container or create a checkpoint (i.e. an image) out of stopped container to run something else. One has to run docker remove before launching container under the same name.

How to remove container once it is stopped automatically? Add an --rm flag to run command:

docker run --rm --name dname image_name bash -c "whoami"

How to execute multiple commands in a single container? By preventing that root process from dying. This can be done by running some useless command at start with --detached flag and then using "execute" to run actual commands:

docker run --rm -d --name dname image_name tail -f /dev/null
docker exec dname bash -c "whoami"
docker exec dname bash -c "echo 'Nnice'"

Why do we need docker stop then? To stop this lingering container that we launched in the previous snippet with the endless command tail -f /dev/null.

Also if you want to do something like ClassB.Run("thing");, make sure the Method Run(); is static or you could call it like this: thing.Run("thing");.

As of swift 3.0 .normal state has been removed.you can use following to apply normal state.

myButton.setTitle("myTitle", for: [])

We cannot prevent the status appearing in full screen mode in (4.4+) kitkat or above devices, so try a hack to block the status bar from expanding.

Solution is pretty big, so here's the link of SO:

StackOverflow : Hide status bar in android 4.4+ or kitkat with Fullscreen

df[cols] = pd.to_numeric(df[cols].stack(), errors='coerce').unstack()

You can just add an input type = reset with an id = resetform like this

<html>
<form>
<input type = 'reset' id = 'resetform' value = 'reset'/>
<!--Other items in the form can be placed here-->
</form>
</html>

then with jquery you simply use the .click() function on the element with the id = resetform as follows

<script> 
$('#resetform').click();
</script>

and the form resets Note: You can also hide the reset button with id = resetform using your css

<style>
#resetform
{
display:none;
}
</style>

Make sure your resource directory (e.g. "src") is in your classpath (make sure it's a source directory in your build path in eclipse).

Make sure clazz is loaded from the main classloader.

Then, to load src/initialization/Lifepaths.txt, use

clazz.getResourceAsStream("/initialization/Lifepaths.txt");

Why: clazz.getResourcesAsStream(foo) looks up foo from within the classpath of clazz, relative to the directory clazz lives in. The leading "/" makes it load from the root of any directory in the classpath of clazz.

Unless you're in a container of some kind, like Tomcat, or are doing something with ClassLoaders directly, you can just treat your eclipse/command line classpath as the only classloader classpath.

This worked for me ::-

mysql --host=hostNameorIp --user=username --password=password  

or

mysql --host=hostNameorIp --user=username --password=password database_name

Probably the simplest way to do it is to create a delegate and then BeginInvoke, followed by a wait at some time in the future, and an EndInvoke.

public bool Foo(){
    Thread.Sleep(100000); // Do work
    return true;
}

public SomeMethod()
{
    var fooCaller = new Func<bool>(Foo);
    // Call the method asynchronously
    var asyncResult = fooCaller.BeginInvoke(null, null);

    // Potentially do other work while the asynchronous method is executing.

    // Finally, wait for result
    asyncResult.AsyncWaitHandle.WaitOne();
    bool fooResult = fooCaller.EndInvoke(asyncResult);

    Console.WriteLine("Foo returned {0}", fooResult);
}

Alternatively, you can also parse a standard markdown document (without code blocks per se) on the fly by the markdownreports package.

For a class Book like this:

package books;

public class Book {

    private Integer id;
    private Integer number;
    private String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public Integer getNumber() {
        return number;
    }

    public void setNumber(Integer number) {
        this.number = number;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "book{" +
                "id=" + id +
                ", number=" + number +
                ", name='" + name + '\'' + '\n' +
                '}';
    }
}

Keypress event is deprecated, You should use Keydown event instead.

https://developer.mozilla.org/en-US/docs/Web/API/Document/keypress_event

handleKeyDown(event) {
    if(event.keyCode === 13) { 
        console.log('Enter key pressed')
  }
}

render() { 
    return <input type="text" onKeyDown={this.handleKeyDown} /> 
}

There are two ways to go about this. You can either use the IDE to generate a WSDL, or you can do it via the command line.

1. To create it via the IDE:

In the solution explorer pane, right click on the project that you would like to add the Service to:

Then, you can enter the path to your service WSDL and hit go:

2. To create it via the command line:

Open a VS 2010 Command Prompt (Programs -> Visual Studio 2010 -> Visual Studio Tools)
Then execute:

WSDL /verbose C:\path\to\wsdl

WSDL.exe will then output a .cs file for your consumption.

If you have other dependencies that you received with the file, such as xsd's, add those to the argument list:

WSDL /verbose C:\path\to\wsdl C:\path\to\some\xsd C:\path\to\some\xsd

If you need VB output, use /language:VB in addition to the /verbose.

Try this formula (it will return value from A1 as is if it's not a date):

=TEXT(A1,"mm-yyyy")

Or this formula (it's more strict, it will return #VALUE error if A1 is not date):

=TEXT(MONTH(A1),"00")&"-"&YEAR(A1)

Just use CASCADE

TRUNCATE "products" RESTART IDENTITY CASCADE;

But be ready for cascade deletes )

If you find the notation awkward, maybe the -R-option does help. It outpouts the date in RFC 2822 format. So you won't need all those identifiers: date -d @1278999698 -R. Another possibility is to output the date in seconds in your locale: date -d @1278999698 +%c. Should be easy to remember. :-)

I have a Windows service, and I added the following line to the constructor for my service:

using System.Diagnostics;
try {
    Process p = Process.Start(@"C:\Windows\system32\calc.exe");
} catch {
    Debugger.Break();
}

When I tried to run this, the Process.Start() call was made, and no exception occurred. However, the calc.exe application did not show up. In order to make it work, I had edit the properties for my service in the Service Control Manager to enable interaction with the desktop. After doing that, the Process.Start() opened calc.exe as expected.

But as others have said, interaction with the desktop is frowned upon by Microsoft and has essentially been disabled in Vista. So even if you can get it to work in XP, I don't know that you'll be able to make it work in Vista.

For me, the user was mongod instead of mongodb

sudo chown mongod:mongod /newlocation

You can see the logs for errors if the service fails:

/var/log/mongodb/mongod.log

Try this code it works:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    MsgBox(CustomeDate.ToString)

    dadap = New System.Data.OleDb.OleDbDataAdapter("SELECT * FROM QRY_Tran where FORMAT(qry_tran.doe,'d/mm/yyyy') = " & CustomeDate & "", con)

    ds = New System.Data.DataSet
    dadap.Fill(ds)
    Dgview.DataSource = ds.Tables(0)
    con.Close()

Note : if u use dd for date representation it will return nothing while selecting 1 to 9 so use d for selection

'Date time format
'MMM     Three-letter month.
'ddd     Three-letter day of the week.
'd       Day of the month.
'HH      Two-digit hours on 24-hour scale.
'mm      Two-digit minutes.
'yyyy    Four-digit year.

The documentation contains a full list of the date formats.

After you tried Clean and Rebuild without success, check your res folder for corrupted files.

In my case a corrupted .png file caused all the trouble.

I don't believe this is possible, easily. The only way I believe to get around this is to make your own back button arrow image to place up there. It was frustrating for me at first but I see why, for consistency's sake, it was left out.

You can get close (without the arrow) by creating a regular button and hiding the default back button:

self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Servers" style:UIBarButtonItemStyleDone target:nil action:nil] autorelease];
self.navigationItem.hidesBackButton = YES;

It really all comes down to how you want to handle output that the command might return and whether you want your PHP script to wait for the callee program to finish or not.

• exec executes a command and passes output to the caller (or returns it in an optional variable).

• passthru is similar to the exec() function in that it executes a command . This function should be used in place of exec() or system() when the output from the Unix command is binary data which needs to be passed directly back to the browser.

• system executes an external program and displays the output, but only the last line.

If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function.

The Rule of Three is a rule of thumb for C++, basically saying

If your class needs any of

• a copy constructor,
• an assignment operator,
• or a destructor,

defined explictly, then it is likely to need all three of them.

The reasons for this is that all three of them are usually used to manage a resource, and if your class manages a resource, it usually needs to manage copying as well as freeing.

If there is no good semantic for copying the resource your class manages, then consider to forbid copying by declaring (not defining) the copy constructor and assignment operator as private.

(Note that the forthcoming new version of the C++ standard (which is C++11) adds move semantics to C++, which will likely change the Rule of Three. However, I know too little about this to write a C++11 section about the Rule of Three.)

I had the same problem. I had another program open that was using my laptop's camera. So I closed that program, and then everything worked. I found this answer by checking https://howto.streamlabs.com/streamlabs-obs-9/black-screen-when-using-video-capture-device-elgato-hd-60s-9508.

You can alternatively download winutils.exe from GITHub:

https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin

replace hadoop-2.7.1 with the version you want and place the file in D:\hadoop\bin

If you do not have access rights to the environment variable settings on your machine, simply add the below line to your code:

System.setProperty("hadoop.home.dir", "D:\\hadoop");

(DateTime.Parse((Eval("date").ToString()))).DayOfWeek.ToString()

at the place of Eval("date"),you can use any date...get name of day

Another interesting solution to luch an exeternal application with a WinForm container is the follow:

[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);


private void Form1_Load(object sender, EventArgs e)
{
    ProcessStartInfo psi = new ProcessStartInfo("notepad.exe");
    psi.WindowStyle = ProcessWindowStyle.Minimized;
    Process p = Process.Start(psi);
    Thread.Sleep(500);
    SetParent(p.MainWindowHandle, panel1.Handle);
    CenterToScreen();
    psi.WindowStyle = ProcessWindowStyle.Normal;
}

The step to ProcessWindowStyle.Minimized from ProcessWindowStyle.Normal remove the annoying delay.

General

Single elements of a tuple a can be accessed -in an indexed array-like fashion-

via a[0], a[1], ... depending on the number of elements in the tuple.

Example

If your tuple is a=(3,"a")

• a[0] yields 3,
• a[1] yields "a"

Concrete answer to question

def tup():
  return (3, "hello")

tup() returns a 2-tuple.

In order to "solve"

i = 5 + tup()  # I want to add just the three

you select the 3 by

tup()[0|    #first element

so in total

i = 5 + tup()[0]

Alternatives

Go with namedtuple that allows you to access tuple elements by name (and by index). Details at https://docs.python.org/3/library/collections.html#collections.namedtuple

>>> import collections
>>> MyTuple=collections.namedtuple("MyTuple", "mynumber, mystring")
>>> m = MyTuple(3, "hello")
>>> m[0]
3
>>> m.mynumber
3
>>> m[1]
'hello'
>>> m.mystring
'hello'

INDEX=0
for i in $list; do 
    echo ${INDEX}_$i
    let INDEX=${INDEX}+1
done

.success() only gets called if your webserver responds with a 200 OK HTTP header - basically when everything is fine.

The callbacks attached to done() will be fired when the deferred is resolved. The callbacks attached to fail() will be fired when the deferred is rejected.

promise.done(doneCallback).fail(failCallback)

.done() has only one callback and it is the success callback

you can also use a hashmap for this

@GetMapping
public HashMap<String, Object> get() {
    HashMap<String, Object> map = new HashMap<>();
    map.put("key1", "value1");
    map.put("results", somePOJO);
    return map;
}

Edit: The answer below may be satisfactory, but it has some drawbacks:

1. There is a noticeable pause for the running of the script. I'm on a 160 ms latency, and it's enough to be annoying.

2. It works by building a new range each time you edit a given row. This gives an 'invalid contents' to previous entries some of the time

I hope others can clean this up somewhat.

Here's another way to do it, that saves you a ton of range naming:

Three sheets in the worksheet: call them Main, List, and DRange (for dynamic range.) On the Main sheet, column 1 contains a timestamp. This time stamp is modified onEdit.

On List your categories and subcategories are arranged as a simple list. I'm using this for plant inventory at my tree farm, so my list looks like this:

Group   | Genus | Bot_Name
Conifer | Abies | Abies balsamea
Conifer | Abies | Abies concolor
Conifer | Abies | Abies lasiocarpa var bifolia
Conifer | Pinus | Pinus ponderosa
Conifer | Pinus | Pinus sylvestris
Conifer | Pinus | Pinus banksiana
Conifer | Pinus | Pinus cembra
Conifer | Picea | Picea pungens
Conifer | Picea | Picea glauca
Deciduous | Acer | Acer ginnala
Deciduous | Acer | Acer negundo
Deciduous | Salix | Salix discolor
Deciduous | Salix | Salix fragilis
...

Where | indicates separation into columns.
For convenience I also used the headers as names for named ranges.

DRrange A1 has the formula

=Max(Main!A2:A1000)

This returns the most recent timestamp.

A2 to A4 have variations on:

=vlookup($A$1,Inventory!$A$1:$E$1000,2,False) 

with the 2 being incremented for each cell to the right.

On running A2 to A4 will have the currently selected Group, Genus and Species.

Below each of these, is a filter command something like this:

=unique(filter(Bot_Name,REGEXMATCH(Bot_Name,C1)))

These filters will populate a block below with matching entries to the contents of the top cell.

The filters can be modified to suit your needs, and to the format of your list.

Back to Main: Data validation in Main is done using ranges from DRange.

The script I use:

function onEdit(event) {

  //SETTINGS
  var dynamicSheet='DRange'; //sheet where the dynamic range lives
  var tsheet = 'Main'; //the sheet you are monitoring for edits
  var lcol = 2; //left-most column number you are monitoring; A=1, B=2 etc
  var rcol = 5; //right-most column number you are monitoring
  var tcol = 1; //column number in which you wish to populate the timestamp
  //

  var s = event.source.getActiveSheet();
  var sname = s.getName();
  if (sname == tsheet) {
    var r = event.source.getActiveRange();
    var scol = r.getColumn();  //scol is the column number of the edited cell
    if (scol >= lcol && scol <= rcol) {
      s.getRange(r.getRow(), tcol).setValue(new Date());
      for(var looper=scol+1; looper<=rcol; looper++) {
         s.getRange(r.getRow(),looper).setValue(""); //After edit clear the entries to the right
      }
    }
  }
}

Original Youtube presentation that gave me most of the onEdit timestamp component: https://www.youtube.com/watch?v=RDK8rjdE85Y

For a user control named myPartial.ascx located at Views/Account folder write like this:

<%Html.RenderPartial("~/Views/Account/myPartial.ascx");%>

In your example, the second return will never happen - the first return is the last thing PHP will run. If you need to return multiple values, return an array:

function test($testvar) {

    return array($var1, $var2);
}

$result = test($testvar);
echo $result[0]; // $var1
echo $result[1]; // $var2

just another way to do this based on the content of input variable:

(it returns the name of the first variable that matches to the input variable, otherwise None. One can modify it to get all variable names which are having the same content as input variable)

def retrieve_name(x, Vars=vars()):
    for k in Vars:
        if type(x) == type(Vars[k]):
            if x is Vars[k]:
                return k
    return None

Ahah! Checkout the previous commit, then checkout the master.

For me, the perfect example for threading is monitoring asynchronous events. Look at this code.

# thread_test.py
import threading
import time

class Monitor(threading.Thread):
    def __init__(self, mon):
        threading.Thread.__init__(self)
        self.mon = mon

    def run(self):
        while True:
            if self.mon[0] == 2:
                print "Mon = 2"
                self.mon[0] = 3;

You can play with this code by opening an IPython session and doing something like:

>>> from thread_test import Monitor
>>> a = [0]
>>> mon = Monitor(a)
>>> mon.start()
>>> a[0] = 2
Mon = 2
>>>a[0] = 2
Mon = 2

Wait a few minutes

>>> a[0] = 2
Mon = 2

What I ended up doing is create a new KeyContainer name based off of the current DateTime (DateTime.Now.Ticks.ToString()) whenever I need to create a new key and save the container name and public key to the database. Also, whenever I create a new key I would do the following:

public static string ConvertToNewKey(string oldPrivateKey)
{

    // get the current container name from the database...

    rsa.PersistKeyInCsp = false;
    rsa.Clear();
    rsa = null;

    string privateKey = AssignNewKey(true); // create the new public key and container name and write them to the database...

       // re-encrypt existing data to use the new keys and write to database...

    return privateKey;
}
public static string AssignNewKey(bool ReturnPrivateKey){
     string containerName = DateTime.Now.Ticks.ToString();
     // create the new key...
     // saves container name and public key to database...
     // and returns Private Key XML.
}

before creating the new key.

The provided examples, using csv modules, are great! Besides, you can always simply write to a text file using formatted strings, like the following tentative example:

l = [[1, 2], [2, 3], [4, 5]]

out = open('out.csv', 'w')
for row in l:
    for column in row:
        out.write('%d;' % column)
    out.write('\n')
out.close()

I used ; as separator, because it works best with Excell (one of your requirements).

Hope it helps!

This solution works for both python and jython.

module os_identify.py:

import platform
import os

# This module contains functions to determine the basic type of
# OS we are running on.
# Contrary to the functions in the `os` and `platform` modules,
# these allow to identify the actual basic OS,
# no matter whether running on the `python` or `jython` interpreter.

def is_linux():
    try:
        platform.linux_distribution()
        return True
    except:
        return False

def is_windows():
    try:
        platform.win32_ver()
        return True
    except:
        return False

def is_mac():
    try:
        platform.mac_ver()
        return True
    except:
        return False

def name():
    if is_linux():
        return "Linux"

        return "Windows"
    elif is_mac():

Use like this:

import os_identify

print "My OS: " + os_identify.name()

You may have spaces or tabs in your "empty" line. Use POSIX classes with sed to remove all lines containing only whitespace:

sed '/^[[:space:]]*$/d'

A shorter version that uses ERE, for example with gnu sed:

sed -r '/^\s*$/d'

(Note that sed does NOT support PCRE.)

I was facing the same issue for a couple of days then I figure out that the Oracle.DataAccess is available in the references list of the project, but in the bin folder is missing. So I removed it from the references list and readded again.

set -x enables a mode of the shell where all executed commands are printed to the terminal. In your case it's clearly used for debugging, which is a typical use case for set -x: printing every command as it is executed may help you to visualize the control flow of the script if it is not functioning as expected.

set +x disables it.

Just drag APK file to android emulator it will install automatically.

To differentiate the routes, try adding a constraint that id must be numeric:

RouteTable.Routes.MapHttpRoute(
         name: "DefaultApi",
         routeTemplate: "api/{controller}/{id}",
         constraints: new { id = @"\d+" }, // Only matches if "id" is one or more digits.
         defaults: new { id = System.Web.Http.RouteParameter.Optional }
         );  

You cat use setVisible () method of JFrame (and set visibility to false) or dispose () method which is more similar to close operation.

Try this:

video {
display:block;
margin:0 auto;
}

Difference between STATIC MEMORY ALLOCATION & DYNAMIC MEMORY ALLOCATION

Memory is allocated before the execution of the program begins (During Compilation).
Memory is allocated during the execution of the program.

No memory allocation or deallocation actions are performed during Execution.
Memory Bindings are established and destroyed during the Execution.

Variables remain permanently allocated.
Allocated only when program unit is active.

Implemented using stacks and heaps.
Implemented using data segments.

Pointer is needed to accessing variables.
No need of Dynamically allocated pointers.

Faster execution than Dynamic.
Slower execution than static.

More memory Space required.
Less Memory space required.

Using jQuery 1.9.1 I just found out that, although technically identical)*, this did not work in IE10 (but in Firefox):

// did not work in IE10
$(function() {
    $(window).resize(CmsContent.adjustSize);
});

while this worked in both browsers:

// did work in IE10
$(function() {
    $(window).bind('resize', function() {
        CmsContent.adjustSize();
    };
});

Edit:
)* Actually not technically identical, as noted and explained in the comments by WraithKenny and Henry Blyth.

You should also use <label for="checkbox1">Checkbox 1</label> because then people can click on the label text as well as the checkbox itself. Its also easier to style and at least in IE it will be highlighted when you tab through the page's controls.

<%= Html.CheckBox("cbNewColors", true) %><label for="cbNewColors">New colors</label>

This is not just a 'oh I could do it' thing. Its a significant user experience enhancement. Even if not all users know they can click on the label many will.

bool exists in the current C - C99, but not in C89/90.

In C99 the native type is actually called _Bool, while bool is a standard library macro defined in stdbool.h (which expectedly resolves to _Bool). Objects of type _Bool hold either 0 or 1, while true and false are also macros from stdbool.h.

Note, BTW, that this implies that C preprocessor will interpret #if true as #if 0 unless stdbool.h is included. Meanwhile, C++ preprocessor is required to natively recognize true as a language literal.

If you need to both get the raw content from the request, but also need to use a bound model version of it in the controller, you will likely get this exception.

NotSupportedException: Specified method is not supported. 

For example, your controller might look like this, leaving you wondering why the solution above doesn't work for you:

public async Task<IActionResult> Index(WebhookRequest request)
{
    using var reader = new StreamReader(HttpContext.Request.Body);

    // this won't fix your string empty problems
    // because exception will be thrown
    reader.BaseStream.Seek(0, SeekOrigin.Begin); 
    var body = await reader.ReadToEndAsync();

    // Do stuff
}

You'll need to take your model binding out of the method parameters, and manually bind yourself:

public async Task<IActionResult> Index()
{
    using var reader = new StreamReader(HttpContext.Request.Body);

    // You shouldn't need this line anymore.
    // reader.BaseStream.Seek(0, SeekOrigin.Begin);

    // You now have the body string raw
    var body = await reader.ReadToEndAsync();

    // As well as a bound model
    var request = JsonConvert.DeserializeObject<WebhookRequest>(body);
}

It's easy to forget this, and I've solved this issue before in the past, but just now had to relearn the solution. Hopefully my answer here will be a good reminder for myself...

This is what I use to upload the image through upload window:

    //open upload window
    upload.click();

    //put path to your image in a clipboard
    StringSelection ss = new StringSelection("C:\\IMG_3827.JPG");
    Toolkit.getDefaultToolkit().getSystemClipboard().setContents(ss, null);

    //imitate mouse events like ENTER, CTRL+C, CTRL+V
    Robot robot = new Robot();
    robot.keyPress(KeyEvent.VK_ENTER);
    robot.keyRelease(KeyEvent.VK_ENTER);

    robot.keyRelease(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_ENTER);
    robot.keyRelease(KeyEvent.VK_ENTER);

By having the .5s delay on transitioning the opacity property, the element will be completely transparent (and thus invisible) the whole time its height is transitioning. So the only thing you will actually see is the opacity changing. So you will get the same effect as leaving the height property out of the transition :

"transition: opacity .5s .5s;"

Is that what you're wanting? If not, and you're wanting to see the height transition, you can't have an opacity of zero during the whole time that it's transitioning.

printing a list can also cause this problem (im new in python, so it confused me a bit too):

>>>myList = ['\\']
>>>print myList
['\\']
>>>print ''.join(myList)
\ 

similarly:

>>>myList = ['\&']
>>>print myList
['\\&']
>>>print ''.join(myList)

The problem is that IE won't reset the proxy settings until it either

1. closes, or
2. has its configuration refreshed.

Below is the code that I've used to get this working:

function Refresh-System

  $signature = @'
[DllImport("wininet.dll", SetLastError = true, CharSet=CharSet.Auto)]
public static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength);

$INTERNET_OPTION_REFRESH            = 37
$type = Add-Type -MemberDefinition $signature -Name wininet -Namespace pinvoke -PassThru
$a = $type::InternetSetOption(0, $INTERNET_OPTION_SETTINGS_CHANGED, 0, 0)
$b = $type::InternetSetOption(0, $INTERNET_OPTION_REFRESH, 0, 0)
return $a -and $b
}

Check the collation type of each table, and make sure that they have the same collation.

After that check also the collation type of each table field that you have use in operation.

I had encountered the same error, and that tricks works on me.

The accepted answer answers the question about getting a thread id, but it doesn't let you do "Thread X of Y" messages. Thread ids are unique across threads but don't necessarily start from 0 or 1.

Here is an example matching the question:

import java.util.concurrent.*;
class ThreadIdTest {

  public static void main(String[] args) {

    final int numThreads = 5;
    ExecutorService exec = Executors.newFixedThreadPool(numThreads);

    for (int i=0; i<10; i++) {
      exec.execute(new Runnable() {
        public void run() {
          long threadId = Thread.currentThread().getId();
          System.out.println("I am thread " + threadId + " of " + numThreads);
        }
      });
    }

    exec.shutdown();
  }
}

and the output:

burhan@orion:/dev/shm$ javac ThreadIdTest.java && java ThreadIdTest
I am thread 8 of 5
I am thread 9 of 5
I am thread 10 of 5
I am thread 8 of 5
I am thread 9 of 5
I am thread 11 of 5
I am thread 8 of 5
I am thread 9 of 5
I am thread 10 of 5
I am thread 12 of 5

A slight tweak using modulo arithmetic will allow you to do "thread X of Y" correctly:

// modulo gives zero-based results hence the +1
long threadId = Thread.currentThread().getId()%numThreads +1;

New results:

burhan@orion:/dev/shm$ javac ThreadIdTest.java && java ThreadIdTest  
I am thread 2 of 5 
I am thread 3 of 5 
I am thread 3 of 5 
I am thread 3 of 5

count of the contained lists in the outmost list

int count = data.size();

lambda to get the count of the contained inner lists

int count = data.stream().collect( summingInt(l -> l.size()) );

None of the above answers helped me. I was struggling to understand why code works in Java but not in Kotlin.

Then I figured it out from this thread.

You have to make class and member functions open, otherwise NPE was being thrown.

After making function open tests started to pass.

You might as well consider using compiler's "all-open" plugin:

Kotlin has classes and their members final by default, which makes it inconvenient to use frameworks and libraries such as Spring AOP that require classes to be open. The all-open compiler plugin adapts Kotlin to the requirements of those frameworks and makes classes annotated with a specific annotation and their members open without the explicit open keyword.

If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';

Using this you can export your child class as -

class MyApp extends Component{
    // your code
}

export default withRouter(MyApp);

And your class with Router -

// your code
<Router>
      ...
      <Route path="/myapp" component={MyApp} />
      // or if you are sending additional fields
      <Route path="/myapp" component={() =><MyApp process={...} />} />
<Router>

var path = document.getElementById('upload').value;//take path
var tokens= path.split('\\');//split path
var filename = tokens[tokens.length-1];//take file name

Google Play services has two APIs you can use to streamline the SMS-based verification process

SMS Retriever API

Provides a fully automated user experience, without requiring the user to manually type verification codes and without requiring any extra app permissions and should be used when possible. It does, however, require you to place a custom hash code in the message body, so you must have control over server side as well.

• Message requirements - 11-digit hash code that uniquely identifies your app
• Sender requirements - None
• User interaction - None

Request SMS Verification in an Android App

Perform SMS Verification on a Server

SMS User Consent API

Does not require the custom hash code, however require the user to approve your app's request to access the message containing the verification code. In order to minimize the chances of surfacing the wrong message to the user, SMS User Consent will filter out messages from senders in the user's Contacts list.

• Message requirements - 4-10 digit alphanumeric code containing at least one number
• Sender requirements - Sender cannot be in the user's Contacts list
• User interaction - One tap to approve

The SMS User Consent API is part of Google Play Services. To use it you’ll need at least version 17.0.0 of these libraries:

implementation "com.google.android.gms:play-services-auth:17.0.0"
implementation "com.google.android.gms:play-services-auth-api-phone:17.1.0"

Step 1: Start listening for SMS messages

SMS User Consent will listen for incoming SMS messages that contain a one-time-code for up to five minutes. It won’t look at any messages that are sent before it’s started. If you know the phone number that will send the one-time-code, you can specify the senderPhoneNumber, or if you don’t null will match any number.

 smsRetriever.startSmsUserConsent(senderPhoneNumber /* or null */)

Step 2: Request consent to read a message

Once your app receives a message containing a one-time-code, it’ll be notified by a broadcast. At this point, you don’t have consent to read the message — instead you’re given an Intent that you can start to prompt the user for consent. Inside your BroadcastReceiver, you show the prompt using the Intent in the extras. When you start that intent, it will prompt the user for permission to read a single message. They’ll be shown the entire text that they will share with your app.

val consentIntent = extras.getParcelable<Intent>(SmsRetriever.EXTRA_CONSENT_INTENT)
startActivityForResult(consentIntent, SMS_CONSENT_REQUEST)

Step 3: Parse the one-time-code and complete SMS Verification

When the user clicks “Allow” — it’s time to actually read the message! Inside of onActivityResult you can get the full text of the SMS Message from the data:

val message = data.getStringExtra(SmsRetriever.EXTRA_SMS_MESSAGE)

You then parse the SMS message and pass the one-time-code to your backend!

I had your issue and got it working again (on windows 7).

My setup had actually worked at first. I installed postgres and then set up the system PATH variables with C:\Program Files\PostgreSQL\9.6\bin; C:\Program Files\PostgreSQL\9.6\lib. The psql keyword in the command line gave no errors.

I deleted the PATH variables above one at a time to test if they were both really needed. Psql continued to work after I deleted the lib path, but stopped working after I deleted the bin path. When I returned bin, it still didn't work, and the same with lib. I closed and reopened the command line between tries, and checked the path. The problem lingered even though the path was identical to how it had been when working. I re-pasted it.

I uninstalled and reinstalled postgres. The problem lingered. It finally worked after I deleted the spaces between the "; C:..." in the paths and re-saved.

Not sure if it was really the spaces that were the culprit. Maybe the environment variables just needed to be altered and refreshed after the install.

I'm also still not sure if both lib and bin paths are needed since there seems to be some kind of lingering memory for old path configurations. I don't want to test it again though.

HTML5 Time Input

This one is the simplest of the date/time related types, allowing the user to select a time on a 24/12 hour clock, usually depending on the user's OS locale configuration. The value returned is in 24h hours:minutes format, which will look something like 14:30.

More details, including the appearance for each browser, can be found on MDN.

Posting it here as it might help others. In string it might be necessary to pass the quotes to jq. To do the following with jq:

.items[] | select(.name=="string")

in bash you could do

EMAILID=$1
projectID=$(cat file.json | jq -r '.resource[] | select(.username=='\"$EMAILID\"') | .id')

essentially escaping the quotes and passing it on to jq

Out-File defaults to unicode encoding which is why you are seeing the behavior you are. Use -Encoding Ascii to change this behavior. In your case

Out-File -Encoding Ascii -append textfile.txt. 

Add-Content uses Ascii and also appends by default.

"This is a test" | Add-Content textfile.txt.

As for the lack of newline: You did not send a newline so it will not write one to file.

We need to put some kind of control that can wrap text like textblock/textbox

 <Label Width="120" Height="100" >
        <TextBlock TextWrapping="Wrap">
            this is a very long text inside a textblock and this needs to be on multiline.
        </TextBlock>
    </Label>

svn add --force .

This will add any unversioned file in the current directory and all versioned child directories.

In hadoop1.0:

hadoop fs -rmr /PATH/ON/HDFS

In hadoop2.0:

hdfs dfs -rm -R /PATH/ON/HDFS

Use \ to escape , in path

In some cases you might end up having chain of observables, wherein your observable would return another observable. 'flatmap' kind of unwraps the second observable which is buried in the first one and let you directly access the data second observable is spitting out while subscribing.

public void printsOccurences(List<String> words)
{
    var selectQuery =
        from word in words
        group word by word into g
        select new {Word = g.Key, Count = g.Count()};
    foreach(var word in selectQuery)
        Console.WriteLine($"{word.Word}: {word.Count}");*emphasized text*
}

The simple pre-Java8 solution:

ArrayList<Item> filtered = new ArrayList<Item>(); 
for (Item item : items) if (condition(item)) filtered.add(item);

Unfortunately this solution isn't fully generic, outputting a list rather than the type of the given collection. Also, bringing in libraries or writing functions that wrap this code seems like overkill to me unless the condition is complex, but then you can write a function for the condition.

In newer versions of Excel (2013 and up) flash fill might be a simple and quick solution see: Using Flash Fill in Excel .

check window.history.length or simply, history.length

EDIT: some browsers start their history with 0, others with 1. adjust accordingly.

if it has a value of 1, it means it's the first page in that window/tab - then you can have JS redirect you.

<script>
    function backAway(){
        //if it was the first page
        if(history.length === 1){

How about this: 

select * from fab_scheduler where custid = 1334666058 and eventdate = eventdate + INTERVAL 1 DAY

Why do you want to avoid calling entrySet() it does not generally create an entirely new object with its own context, but instead just provide a facade object. Simply speaking entrySet() is a pretty cheap operation.

Although it is quite an old question, another approach is to change AppendDataBoundItems property. So the code will be:

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
                  OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"
                  AppendDataBoundItems="True">
     <asp:ListItem Selected="True" Value="0" Text="Select"></asp:ListItem>
</asp:DropDownList>

Some handy quick functions (if you're not using Boost):

template<typename T>
std::string ToString(const T& v)
{
    std::ostringstream ss;
    ss << v;
    return ss.str();
}

template<typename T>
T FromString(const std::string& str)
{
    std::istringstream ss(str);
    T ret;
    ss >> ret;
    return ret;
}

Example:

int i = FromString<int>(s);
std::string str = ToString(i);

Works for any streamable types (floats etc). You'll need to #include <sstream> and possibly also #include <string>.

Follow below steps to do this or simply use apkToJava gem for this process, it even takes care of installing the required tools for it to work.

• convert apk file to zip
• unzip the file
• extract classes.dex from it
• use dex to jar to convert classes.dex into jar file
• use jadx gui to open the jar file as java source code

If your path contains comma's, putting quotes around the path will work when using Process.Start(ProcessStartInfo).

It will NOT work when using Process.Start(string, string) however. It seems like Process.Start(string, string) actually removes the quotes inside of your args.

Here is a simple example that works for me.

string p = @"C:\tmp\this path contains spaces, and,commas\target.txt";
string args = string.Format("/e, /select, \"{0}\"", p);

ProcessStartInfo info = new ProcessStartInfo();
info.FileName = "explorer";
info.Arguments = args;
Process.Start(info);

Just to add to the other answers, the documentation gives this explanation:

• KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

• A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. For all engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL.

• A PRIMARY KEY is a unique index where all key columns must be defined as NOT NULL. If they are not explicitly declared as NOT NULL, MySQL declares them so implicitly (and silently). A table can have only one PRIMARY KEY. The name of a PRIMARY KEY is always PRIMARY, which thus cannot be used as the name for any other kind of index.

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

I using MDaf just use this code :

DataContext db = new DataContext(ConfigurationManager.ConnectionStrings["con"].ConnectionString);
db.TruncateTable("TABLE_NAME_HERE");
//or
db.Execute("TRUNCATE TABLE TABLE_NAME_HERE ");

For first Date

$_firstDate = date("m-d-Y", strtotime($_yourDateString));

For New Date

$_newDate = date("Y-m-d",strtotime($_yourDateString));

Here is one that works for plain-text with some server side processing:

public string RotateHtmltext(string innerHtml)
{
   const string TRANSFORMTEXT = "transform: rotate(90deg);";
   const string EXTRASTYLECSS = "<style type='text/css'>.r90 {"
                                 + "-webkit-" + TRANSFORMTEXT
                                 + "-moz-" + TRANSFORMTEXT
                                 + "-o-" + TRANSFORMTEXT
                                 + "-ms-" + TRANSFORMTEXT
                                 + "" + TRANSFORMTEXT
                                 + "width:1em;line-height:1ex}</style>";
   const string WRAPPERDIV = "<div style='display: table-cell; vertical-align: middle;'>";

   var newinnerHtml = string.Join("</div>"+WRAPPERDIV, Regex.Split(innerHtml, @"<br */?>").Reverse());

   newinnerHtml = Regex.Replace(newinnerHtml, @"((?:<[^>]*>)|(?:[^<]+))",
                                 match => match.Groups[1].Value.StartsWith("<")
                                             ? match.Groups[1].Value
                                             : string.Join("", match.Groups[1].Value.ToCharArray().Select(x=>"<div class='r90'>"+x+"</div>")),
                                 RegexOptions.Singleline);
   return EXTRASTYLECSS + WRAPPERDIV + newinnerHtml + "</div>";
}

which gives something like:

<style type="text/css">.r90 {
-webkit-transform: rotate(90deg);
-moz-transform: rotate(90deg);
-o-transform: rotate(90deg);
-ms-transform: rotate(90deg);
transform: rotate(90deg);
width: 1em;
line-height: 1ex; 
}</style>
<div style="display: table-cell; vertical-align: middle;">
<div class="r90">p</div>
<div class="r90">o</div>
<div class="r90">s</div>
</div><div style="display: table-cell; vertical-align: middle;">
<div class="r90">(</div>
<div class="r90">A</div>
<div class="r90">b</div>
<div class="r90">s</div>
<div class="r90">)</div>
</div>

getClass() method is defined in Object class with the following signature:

public final Class getClass()

Since it is not defined as static, you can not call it within a static code block. See these answers for more information: Q1, Q2, Q3.

If you're in a static context, then you have to use the class literal expression to get the Class, so you basically have to do like:

Foo.class

This type of expression is called Class Literals and they are explained in Java Language Specification Book as follows:

A class literal is an expression consisting of the name of a class, interface, array, or primitive type followed by a `.' and the token class. The type of a class literal is Class. It evaluates to the Class object for the named type (or for void) as defined by the defining class loader of the class of the current instance.

You can also find information about this subject on API documentation for Class.

public ArrayAdapter (Context context, int resource, int textViewResourceId, T[] objects)

Here, resource means the 'id' of the Layout you are using while instantiating the view.

Now, this layout has many child views with their own ids. So, textViewResourceId tells which child view we need to populate with the data.

// GET DATE & TIME IN ANY FORMAT
import java.util.Calendar;
import java.text.SimpleDateFormat;
public static final String DATE_FORMAT_NOW = "yyyy-MM-dd HH:mm:ss";

public static String now() {
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT_NOW);
return sdf.format(cal.getTime());
}

Since the old accepted answer got deleted (It was a link to a Google code search results that no longer exist), I figured I could answer this question for future reference :

public static DateTime GetNetworkTime()
{
    //default Windows time server
    const string ntpServer = "time.windows.com";

    // NTP message size - 16 bytes of the digest (RFC 2030)
    var ntpData = new byte[48];

    //Setting the Leap Indicator, Version Number and Mode values
    ntpData[0] = 0x1B; //LI = 0 (no warning), VN = 3 (IPv4 only), Mode = 3 (Client Mode)

    var addresses = Dns.GetHostEntry(ntpServer).AddressList;

    //The UDP port number assigned to NTP is 123
    var ipEndPoint = new IPEndPoint(addresses[0], 123);
    //NTP uses UDP

    using(var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp))
    {
        socket.Connect(ipEndPoint);

        //Stops code hang if NTP is blocked
        socket.ReceiveTimeout = 3000;     

        socket.Send(ntpData);
        socket.Receive(ntpData);
        socket.Close();
    }

    //Offset to get to the "Transmit Timestamp" field (time at which the reply 
    //departed the server for the client, in 64-bit timestamp format."
    const byte serverReplyTime = 40;

    //Get the seconds part
    ulong intPart = BitConverter.ToUInt32(ntpData, serverReplyTime);

    //Get the seconds fraction
    ulong fractPart = BitConverter.ToUInt32(ntpData, serverReplyTime + 4);

    //Convert From big-endian to little-endian
    intPart = SwapEndianness(intPart);
    fractPart = SwapEndianness(fractPart);

    var milliseconds = (intPart * 1000) + ((fractPart * 1000) / 0x100000000L);

    //**UTC** time
    var networkDateTime = (new DateTime(1900, 1, 1, 0, 0, 0, DateTimeKind.Utc)).AddMilliseconds((long)milliseconds);

    return networkDateTime.ToLocalTime();
}

// stackoverflow.com/a/3294698/162671

{
    return (uint) (((x & 0x000000ff) << 24) +
                   ((x & 0x0000ff00) << 8) +
                   ((x & 0x00ff0000) >> 8) +
                   ((x & 0xff000000) >> 24));
}

Note: You will have to add the following namespaces

using System.Net;
using System.Net.Sockets;

The relative path works in in java using the . operator.

• . means same folder as the currently running context.
• .. means the parent folder of the currently running context.

So the question is how do you know the path where the java is currently looking?

do a small experiment

   File directory = new File("./");
   System.out.println(directory.getAbsolutePath());

Observe the output , you will come to know the current directory where java is looking . From there , simply use the ./ operator to locate your file.

for example if the output is

G:\JAVA8Ws\MyProject\content.

and your file is present in the folder MyProject simply use

File resourceFile = new File("../myFile.txt");

Hope this helps

An xmlns is a unique identifier within the document - it doesn't have to be a URI to the schema:

XML namespaces provide a simple method for qualifying element and attribute names used in Extensible Markup Language documents by associating them with namespaces identified by URI references.

xsi:schemaLocation is supposed to give a hint as to the actual schema location:

can be used in a document to provide hints as to the physical location of schema documents which may be used for assessment.

Just type "cmd" to location bar, that's it. It will start a new command prompt in current path.

This solution was confirmed to work in Windows XP, Vista, 7, 8 and 10 (including Creators Update).

Keystrokes to move the focus to the location bar:

• AltD in English (pointed out by Tim Stewart in the comments)
• AltE in German

• [ is the same as the test builtin, and works like the test binary (man test)
  • works about the same as [ in all the other sh-based shells in many UNIX-like environments
  • only supports a single condition. Multiple tests with the bash && and || operators must be in separate brackets.
  • doesn't natively support a 'not' operator. To invert a condition, use a ! outside the first bracket to use the shell's facility for inverting command return values.
  • == and != are literal string comparisons
• [[ is a bash
  • is bash-specific, though others shells may have implemented similar constructs. Don't expect it in an old-school UNIX sh.
  • == and != apply bash pattern matching rules, see "Pattern Matching" in man bash
  • has a =~ regex match operator
  • allows use of parentheses and the !, &&, and || logical operators within the brackets to combine subexpressions

Aside from that, they're pretty similar -- most individual tests work identically between them, things only get interesting when you need to combine different tests with logical AND/OR/NOT operations.

Statically typed languages type-check at compile time and the type can NOT change. (Don't get cute with type-casting comments, a new variable/reference is created).

Dynamically typed languages type-check at run-time and the type of an variable CAN be changed at run-time.

name() is a "built-in" method of enum. It is final and you cannot change its implementation. It returns the name of enum constant as it is written, e.g. in upper case, without spaces etc.

Compare MOBILE_PHONE_NUMBER and Mobile phone number. Which version is more readable? I believe the second one. This is the difference: name() always returns MOBILE_PHONE_NUMBER, toString() may be overriden to return Mobile phone number.

For me it worked. More information: https://www.anaconda.com/keeping-anaconda-date/

I had the same error when I create the SQL db in a VM. I had changed the default value of /etc/postgresql/9.3/main/postgresql.conf shared_buffers = 200MB to 75% of my total RAM. Well, I forgot to actually allocate that RAM in the VM. When I gave the command to make a new database, I received the same error.

Powered off, gave the baby its bottle (RAM) and presto, it worked.

One other thing to note, if you updated a legacy app that had structs to use classes you might run into the following issue:

Old code has structs, code was cleaned up and these changed to classes. A virtual function or two was then added to the new updated class.

When virtual functions are in classes then internally the compiler will add extra pointer to the class data to point to the functions.

How this would break old legacy code is if in the old code somewhere the struct was cleared using memfill to clear it all to zeros, this would stomp the extra pointer data as well.

I had the same scenario occuring..Very basic report, the SP (which only takes in 1 param) was taking 5 seconds to bring back 10K records, yet the report would take 6 minutes to run. According to profiler and the RS ExecutionLogStorage table, the report was spending all it's time on the query. Brian S.'s comment led me to the solution..I simply added WITH RECOMPILE before the AS statement in the SP, and now the report time pretty much matches the SP execution time.

I'd just like to add, and please correct me if I'm wrong, that when I embed the HTML5 version of the videos, it doesn't play ads on top.

Not sure if this will ever change. They're probably just trying to work out the best way to show ads on the HTML5 player.

From my experience I would advise great caution with using DoEvents in .NET. I experienced some very strange results when using DoEvents in a TabControl containing DataGridViews. On the other hand, if all you're dealing with is a small form with a progress bar then it might be OK.

The bottom line is: if you are going to use DoEvents, then you need to test it thoroughly before deploying your application.

For Django > 3 I do not change settings or anything. I add the below code in the template file.

{{ request.path }}  #  -without GET parameters 
{{ request.get_full_path }}  # - with GET parameters

and in view.py pass request variable to the template file.

view.py:

def view_node_taxon(request, cid):
    showone = get_object_or_404(models.taxon, id = cid)
    context = {'showone':showone,'request':request}
    mytemplate  = loader.get_template('taxon/node.html')
    html = mytemplate.render(context)
    return HttpResponse(html)

let arr1: boolean[] = [];

console.log(arr1[1]);

arr1.push(true);

You could use

List<DataRow> list = new List<DataRow>(dt.Select());

dt.Select() will return all rows in your table, as an array of datarows, and the List constructor accepts that array of objects as an argument to initially fill your list with.

You just need to provide an alias for your aggregate columns in the CTE

d as (SELECT 
   duration, 
   sum(totalitems) as sumtotalitems
FROM 
   [DrySoftBranch].[dbo].[mnthItemWiseTotalQty] ('1') AS BkdQty

<p>The CSS :active psuedo style is displayed between the time when a user touches down (when finger contacts screen) on a element to the time when the touch up (when finger leaves the screen) occures.   With a typical touch-screen tap interaction, the time of which the :active psuedo style is displayed can be very small resulting in the :active state not showing or being missed by the user entirely.  This can cause issues with users not undertanding if their button presses have actually reigstered or not.</p>

<p>Having the the :active styling stick around for a few hundred more milliseconds after touch up would would improve user understanding when they have interacted with a button.</p>

Integer is an wrapper class/Object and int is primitive type. This difference plays huge role when you want to store int values in a collection, because they accept only objects as values (until jdk1.4). JDK5 onwards because of autoboxing it is whole different story.

I found another reason PSEXEC (and other PS tools) fail - If something (...say, a virus or trojan) hides the Windows folder and/or its files, then PSEXEC will fail with an "Access is Denied" error, PSLIST will give the error "Processor performance object not found on " and you'll be left in the dark as to the reason.

You can RDP in; You can access the admin$ share; You can view the drive contents remotely, etc. etc., but there's no indication that file(s) or folder(s) being hidden is the reason.

I'll be posting this information on several pages that i was perusing yesterday while trying to determine the cause of this odd problem, so you might see this elsewhere verbatim - just thought I'd put the word out before anyone else pulled their hair out by the roots trying to understand why the performance counter has anything to do with PSEXEC running.

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

Here's an example:

$(document).ready( function () {

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

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

 });

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

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

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

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

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

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

In C++ copying the object means cloning. There is no any special cloning in the language.

As the standard suggests, after copying you should have 2 identical copies of the same object.

There are 2 types of copying: copy constructor when you create object on a non initialized space and copy operator where you need to release the old state of the object (that is expected to be valid) before setting the new state.

Try using this code:

var event = new Date();
var options = { weekday: 'long' };
console.log(event.toLocaleDateString('en-US', options));

this will give you the day name in string format.

I tried the solution from Bill using $(document).ready... but at first it did not work. I discovered that if the script is placed after the html section, it will not work. If it is the head section it will work but only in IE. The script does not work in Firefox.

    }
}

If you want to modify only the first commit, you may try git rebase and amend the commit, which is similar to this post: How to modify a specified commit in git?

And if you want to modify all the commits which contain the raw email, filter-branch is the best choice. There is an example of how to change email address globally on the book Pro Git, and you may find this link useful http://git-scm.com/book/en/Git-Tools-Rewriting-History

PYTHONPATH is an environment variable those content is added to the sys.path where Python looks for modules. You can set it to whatever you like.

However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…

I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

You could use extension methods to make it a little more readable:

public static class DateTimeExtensions
{
    public static bool InRange(this DateTime dateToCheck, DateTime startDate, DateTime endDate)
    {
        return dateToCheck >= startDate && dateToCheck < endDate;
    }
}

Now you can write:

dateToCheck.InRange(startDate, endDate)

Rather than abusing plot or annotate, which will be inefficient for many lines, you can use matplotlib.collections.LineCollection:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.collections import LineCollection

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")

# Takes list of lines, where each line is a sequence of coordinates
l1 = [(70, 100), (70, 250)]
l2 = [(70, 90), (90, 200)]
lc = LineCollection([l1, l2], color=["k","blue"], lw=2)

plt.gca().add_collection(lc)

plt.show()

It takes a list of lines [l1, l2, ...], where each line is a sequence of N coordinates (N can be more than two).

The standard formatting keywords are available, accepting either a single value, in which case the value applies to every line, or a sequence of M values, in which case the value for the ith line is values[i % M].

try this:

legend.green-color a:hover{
    text-decoration: none;
}

The sized box will not help in the case, the phone is in landscape mode.

body: Column(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      crossAxisAlignment: CrossAxisAlignment.stretch,
      children: <Widget>[
        Expanded(

            margin: EdgeInsets.all(15.0),
            decoration: BoxDecoration(
              color: Color(0xFF1D1E33),
              borderRadius: BorderRadius.circular(10.0),
            ),
          ),
        ),

              borderRadius: BorderRadius.circular(10.0),

            ),
          ),
        ),
      ],
     )

If you're using glib, then you can use g_file_get_contents;

gchar *contents;
GError *err = NULL;

g_file_get_contents ("foo.txt", &contents, NULL, &err);
g_assert ((contents == NULL && err != NULL) || (contents != NULL && err == NULL));
if (err != NULL)
  {
    // Report error to user, and free error
    g_assert (contents == NULL);
    fprintf (stderr, "Unable to read file: %s\n", err->message);
    g_error_free (err);
  }
else
  {
    // Use file contents
    g_assert (contents != NULL);
  }
}

I encountered this error working in Talend. I was able to store S3 CSV files created from Redshift without a problem. The error occurred when I was trying to load the same S3 CSV files into an Amazon RDS MySQL database. I tried the default timestamp Talend timestamp formats but they were throwing exception:unparseable date when loading into MySQL.

This from the accepted answer helped me solve this problem:

By the way, the "unparseable date" exception can here only be thrown by SimpleDateFormat#parse(). This means that the inputDate isn't in the expected pattern "yyyy-MM-dd HH:mm:ss z". You'll probably need to modify the pattern to match the inputDate's actual pattern

The key to my solution was changing the Talend schema. Talend set the timestamp field to "date" so I changed it to "timestamp" then I inserted "yyyy-MM-dd HH:mm:ss z" into the format string column view a screenshot here talend schema

I had other issues with 12 hour and 24 hour timestamp translations until I added the "z" at the end of the timestamp string.

Ctrl+Shift+D, but you have to put focus on the script output panel first...which you can do via the KB.

Run script.

Alt+PgDn     -  puts you in Script Output panel.
Ctrl+Shift+D -  clears panel.
Alt+PgUp     -  puts you back in editor panel. 

Update with quoted comment by author for better visibility:

Author's note "This project started before Jupyter's execute API, which is now the recommended way to run notebooks from the command-line. Consider runipy deprecated and unmaintained." – Sebastian Palma

Install runipy library that allows running your code on terminal

pip install runipy

After just compiler your code:

runipy <YourNotebookName>.ipynb

You can try cronjob as well. All information is here

Here's a one-liner solution in Ruby.

nums.map { |n| (num - [n]).inject(:*) }

As of Angular 8+ you can use clear() to remove all controls in the FormArray:

const arr = new FormArray([
   new FormControl(),
   new FormControl()
]);
console.log(arr.length);  // 2

arr.clear();
console.log(arr.length);  // 0

For previous versions the recommended way is:

while (arr.length) {
   arr.removeAt(0);
}

https://angular.io/api/forms/FormArray#clear

You can use withCredentials property to pass cookies in the request.

axios.get(`api_url`, { withCredentials: true })

By setting { withCredentials: true } you may encounter cross origin issue. To solve that you need to use

expressApp.use(cors({ credentials: true, origin: "http://localhost:8080" }));

Here you can read about withCredentials

As stated here: Package names are written in all lower case to avoid conflict with the names of classes or interfaces.

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.

Name collisions that occur within a single company need to be handled by convention within that company, perhaps by including the region or the project name after the company name (for example, com.example.region.mypackage).

Packages in the Java language itself begin with java. or javax.

In some cases, the internet domain name may not be a valid package name. This can occur if the domain name contains a hyphen or other special character, if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name, or if the package name contains a reserved Java keyword, such as "int". In this event, the suggested convention is to add an underscore. For example:

204 No Content

The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

According to the RFC part for the status code 204, it seems to me a valid choice for a GET request.

A 404 Not Found, 200 OK with empty body and 204 No Content have completely different meaning, sometimes we can't use proper status code but bend the rules and they will come back to bite you one day or later. So, if you can use proper status code, use it!

I think the choice of GET or POST is very personal as both of them will do the work but I would recommend you to keep a POST instead of a GET, for two reasons:

• You want the other part (the servlet if I understand correctly) to perform an action not retrieve some data from it.
• By default GET requests are cacheable if there are no parameters present in the URL, a POST is not.

IF you have a version greater than 1.8, you can use this to hit the page change events:

    $('#myTable').on('page', function () {...} );

Hope this helps!

UPDATE:

Some comments have pointed out that using .live() instead of .on() worked for them. Be aware of that you should try both and see which one works best in your particular circumstance! (I believe this may have to do with your version on jQuery, but please comment if you find another reason!)

Don't use the depricated mysql_* function (depricated in php 5.5 will be removed in php 7). and you can make this with mysqli or pdo

here is the complete select query

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT id, firstname, lastname FROM MyGuests";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        // code here 
    }
} else {
    echo "0 results";
}
$conn->close();
?>

The objects in the std::set are stored as const StudentT. So when you try to call getId() with the const object the compiler detects a problem, mainly you're calling a non-const member function on const object which is not allowed because non-const member functions make NO PROMISE not to modify the object; so the compiler is going to make a safe assumption that getId() might attempt to modify the object but at the same time, it also notices that the object is const; so any attempt to modify the const object should be an error. Hence compiler generates an error message.

The solution is simple: make the functions const as:

int getId() const {
    return id;
}
string getName() const {
    return name;
}

This is necessary because now you can call getId() and getName() on const objects as:

void f(const StudentT & s)
{
     cout << s.getId();   //now okay, but error with your versions
     cout << s.getName(); //now okay, but error with your versions
}

As a sidenote, you should implement operator< as :

inline bool operator< (const StudentT & s1, const StudentT & s2)
{
    return  s1.getId() < s2.getId();
}

Note parameters are now const reference.

I upgraded the memory of a machine from 2GB to 4GB, and started to get the error straight away:

$ java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

The problem was the ulimit, which I had set at 1GB for the addressable space. Increasing it to 2GB solved the issue.

-Xms and -Xmx had no effect.

Looks like java tries to get memory in proportion to the available memory, and fails if it can't.

First, always sudo nginx -t to verify your config files are good.

I ran into the same problem. The reason I had the issue was twofold. First, I had accidentally copied a log file into my site-enabled folder. I deleted the log file and made sure that all the files in sites-enabled were proper nginx site configs. I also noticed two of my virtual hosts were listening for the same domain. So I made sure that each of my virtual hosts had unique domain names.

sudo service nginx restart

Then it worked.

There are a few alternate ways to figure out the currently used python in Linux is:

1. which python command.
2. command -v python command
3. type python command

Similarly On Windows with Cygwin will also result the same.

kuvivek@HOSTNAME ~
$ which python
/usr/bin/python

kuvivek@HOSTNAME ~
$ whereis python
python: /usr/bin/python /usr/bin/python3.4 /usr/lib/python2.7 /usr/lib/python3.4        /usr/include/python2.7 /usr/include/python3.4m /usr/share/man/man1/python.1.gz

kuvivek@HOSTNAME ~
$ which python3
/usr/bin/python3

kuvivek@HOSTNAME ~
$ command -v python
/usr/bin/python

kuvivek@HOSTNAME ~
$ type python
python is hashed (/usr/bin/python)

If you are already in the python shell. Try anyone of these. Note: This is an alternate way. Not the best pythonic way.

>>> import os
>>> os.popen('which python').read()
'/usr/bin/python\n'
>>>
>>> os.popen('type python').read()
'python is /usr/bin/python\n'
>>>
>>> os.popen('command -v python').read()
'/usr/bin/python\n'
>>>
>>>

If you are not sure of the actual path of the python command and is available in your system, Use the following command.

pi@osboxes:~ $ which python
/usr/bin/python
pi@osboxes:~ $ readlink -f $(which python)
/usr/bin/python2.7
pi@osboxes:~ $ 
pi@osboxes:~ $ which python3
/usr/bin/python3
pi@osboxes:~ $ 
pi@osboxes:~ $ readlink -f $(which python3)
/usr/bin/python3.7
pi@osboxes:~ $ 

A few things I'd like to add here:

1. Using the mailto URL won't work in the simulator as mail.app isn't installed on the simulator. It does work on device though.

2. There is a limit to the length of the mailto URL. If the URL is larger than 4096 characters, mail.app won't launch.

3. There is a new class in OS 3.0 that lets you send an e-mail without leaving your app. See the class MFMailComposeViewController.

Use CONCAT_WS instead:

CONCAT_WS() does not skip empty strings. However, it does skip any NULL values after the separator argument.

SELECT CONCAT_WS('-',`affiliate_name`,`model`,`ip`,`os_type`,`os_version`) AS device_name FROM devices

As stated by others, the filename bootstrap-theme.css is very confusing. I would have chosen something like bootstrap-3d.css or bootstrap-fancy.css which would be more descriptive of what it actually does. What the world sees as a "Bootstrap Theme" is a thing you can get from BootSwatch which is a totally different beast.

With that said, the effects are quite nice - gradients and shadows and such. Unfortunately this file will wreak havoc on BootSwatch Themes, so I decided to dig into what it would take to make it play nice with them.

LESS

Bootstrap-theme.css is generated from the theme.less file in the Bootstrap source. The affected elements are (as of Bootstrap v3.2.0):

• List items
• Buttons
• Images
• Dropdowns
• Navbars
• Alerts
• Progress bars
• List Groups
• Panels
• Wells

The theme.less file depends on:

@import "variables.less";
@import "mixins.less";

The code uses colors defined in variables.less in several places, for example:

// Give the progress background some depth
.progress {
    #gradient > .vertical(@start-color: darken(@progress-bg, 4%); @end-color: @progress-bg)
}

This why bootstrap-theme.css totally messes up BootSwatch Themes. The good news is that BootSwatch Themes are also created from variables.less files, so you can simply build a bootstrap-theme.css for your BootSwatch Theme.

Building bootstrap-theme.css

The right way to do it is to update the Theme build process, but here here is the quick and dirty way. Replace the variables.less file in the Bootstrap source with the one from your Bootswatch Theme and build it and voila you have a bootstrap-theme.css file for your Bootswatch Theme.

Building Bootstrap itself

Building Bootstrap may sound daunting, but it is actually very simple:

1. Download the Bootstrap source code
2. Download and install NodeJS
3. Open a command prompt and navigate to the bootstrap source folder. Type "npm install". This will add the "node_modules" folder to the project and download all the Node stuff you need.
4. Install grunt globally (the -g option) by typing "npm install -g grunt-cli"
5. Rename the "dist" folder to "dist-orig" then rebuild it by typing "grunt dist". Now check that there is a new "dist" folder which contains all you need to use your custom Bootstrap build.

Done. See, that was easy, wasn't it?

To run Selenium WebDriver test cases in Chrome, follow these steps:

1. First of all, set the property and Chrome driver path:

   System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
   

2. Initialize the Chrome Driver's object:

   WebDriver driver = new ChromeDriver();
   

3. Pass the URL into the get method of WebDriver:

   driver.get("http://www.google.com");
   

I don't know why, but for some reason, the "/bin/bash" version didn't work for me. Instead, the simpler version worked, following the example given here at Oracle Docs.

String[] args = new String[] {"ping", "www.google.com"};
Process proc = new ProcessBuilder(args).start();

Laravel 419 post error is usually related with api.php and token authorization

Laravel automatically generates a CSRF "token" for each active user session managed by the application. This token is used to verify that the authenticated user is the one actually making the requests to the application.

Add this to your ajax call

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});

or you can exclude some URIs in VerifyCSRF token middleware

 protected $except = [
        '/route_you_want_to_ignore',
        '/route_group/*
    ];

The easiest would be to use a regular expression with g flag to replace all instances:

str.replace(/foo/g, "bar")

This will replace all occurrences of foo with bar in the string str. If you just have a string, you can convert it to a RegExp object like this:

var pattern = "foobar",
    re = new RegExp(pattern, "g");

Also you can try zenity !

user=$(zenity --entry --text 'Please enter the username:') || exit 1

It is a sort of format specifier for formatting numeric results. There are additional specifiers on the link.

What N does is that it separates numbers into thousand decimal places according to your CultureInfo and represents only 2 decimal digits in floating part as is N2 by rounding right-most digit if necessary.

N0 does not represent any decimal place but rounding is applied to it.

Let's exemplify.

using System;
using System.Globalization;


namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            double x = 567892.98789;
            CultureInfo someCulture = new CultureInfo("da-DK", false);

            // 10 means left-padded = right-alignment
            Console.WriteLine(String.Format(someCulture, "{0:N} denmark", x));
            Console.WriteLine("{0,10:N} us", x); 

            // watch out rounding 567,893
            Console.WriteLine(String.Format(someCulture, "{0,10:N0}", x)); 
            Console.WriteLine("{0,10:N0}", x);

            Console.WriteLine(String.Format(someCulture, "{0,10:N5}", x));
            Console.WriteLine("{0,10:N5}", x);


            Console.ReadKey();

        }
    }
}

It yields,

567.892,99 denmark
567,892.99 us
   567.893
   567,893
567.892,98789
567,892.98789

I can't explain why, but changing url parameter from having localhost to 127.0.0.1 on mongodb.MongoClient.connect() method on Windows 10 solved the issue.

If you know the actual enum labels correlated to their values, you can use containers and C++17's std::string_view to quickly access values and their string representations with the [ ] operator while tracking it yourself. std::string_view will only allocate memory when created. They can also be designated with static constexpr if you want them available at run-time for more performance savings. This little console app should be fairly fast.

#include <iostream>
#include <string_view>
#include <tuple>    
int main() {
    enum class Weekdays { //default behavior starts at 0 and iterates by 1 per entry
        Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday
    };

    static constexpr std::string_view Monday    = "Monday";
    static constexpr std::string_view Tuesday   = "Tuesday";
    static constexpr std::string_view Wednesday = "Wednesday";
    static constexpr std::string_view Thursday  = "Thursday";
    static constexpr std::string_view Friday    = "Friday";
    static constexpr std::string_view Saturday  = "Saturday";
    static constexpr std::string_view Sunday    = "Sunday";
    static constexpr std::string_view opener    = "enum[";
    static constexpr std::string_view closer    = "] is ";
    static constexpr std::string_view semi      = ":";

    std::pair<Weekdays, std::string_view> Weekdays_List[] = {
        std::make_pair(Weekdays::Monday,    Monday),
        std::make_pair(Weekdays::Tuesday,   Tuesday),
        std::make_pair(Weekdays::Wednesday, Wednesday),
        std::make_pair(Weekdays::Thursday,  Thursday),
        std::make_pair(Weekdays::Friday,    Friday),
        std::make_pair(Weekdays::Saturday,  Saturday),
        std::make_pair(Weekdays::Sunday,    Sunday)
    };

    for (int i=0;i<sizeof(Weekdays_List)/sizeof(Weekdays_List[0]);i++) {
        std::cout<<opener<<i<<closer<<Weekdays_List[(int)i].second<<semi\
        <<(int)Weekdays_List[(int)i].first<<std::endl;
    }    
    return 0;
}

Output:

enum[0] is Monday:0
enum[1] is Tuesday:1
enum[2] is Wednesday:2
enum[3] is Thursday:3
enum[4] is Friday:4
enum[5] is Saturday:5
enum[6] is Sunday:6

Try this: It works in any case, if the file doesn't exists, it will create it and then write to it. And if already exists, no problem it will open and write to it :

using (FileStream fs= new FileStream(@"File.txt",FileMode.Create,FileAccess.ReadWrite))
{ 
     fs.close();
}
using (StreamWriter sw = new StreamWriter(@"File.txt")) 
 { 
    sw.WriteLine("bla bla bla"); 
    sw.Close(); 
 } 

GitHub's support determined the root of the issue right away: Two-factor authorization.

To use GitHub over the shell with https, create an OAuth token. As the page notes, I did have to remove my username and password credentials from Keychain but with osx-keychain in place, the token is stored as the password and things work exactly as they would over https without two-factor authorization in place.

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

will give you what you need
