Programs & Examples On #Saas

Meaning For dummies:

IAAS (Infrastructure As A Service) :

• The base layer

• Deals with Virtual Machines, Storage (Hard Disks), Servers, Network, Load Balancers etc

PAAS (Platform As A Service) :

• A layer on top of IAAS

• Runtimes (like java runtimes), Databases (like mySql, Oracle), Web Servers (tomcat etc)

SAAS (Software As A Service) :

• A layer on top on PAAS

• Applications like email (Gmail, Yahoo mail etc), Social Networking sites (Facebook etc)

To quickly relate consider the below Google's offerings:

IAAS : Google Compute Engine (One can develop programs to be run on high performing google's computing infrastructure)

PAAS : Google App Engine (One can develop applications and let them execute on top of Google app engine which take care of the execution)

SAAS : Gmail, Google+ etc (One can use email services and extend email/google+ based applications to form newer applications)

Popularity

Company Wise Popularity

Cloud computing is dominated by

1. Amazon Web Services (AWS),
2. Google Compute Engine, Google App Engine
3. Microsoft Azure
4. There are many small and medium scale cloud operators that include IBM, Oracle etc.

Most of the popularity around these services owe to the reputation of the company and the amount of investments being made by these companies around the cloud space.

Type of Service Wise Popularity

1. PAAS (Platform as a Service) is more popular among developers as they can put all their concentration on developing their apps and leave the rest of management and execution to the service provider. Many service providers also offer the flexibility to increase/decrease the CPU power depending upon the traffic loads giving developers cost effective and easy & effortless management.
2. SAAS (Software as a service) is more popular among with consumers, who bother about using the application such as email, social networking etc
3. IAAS (Infrastructure as a service) is more popular among users into research and high computing areas.

You might be interested in pyp. Citing my other answer:

"The Pyed Piper", or pyp, is a linux command line text manipulation tool similar to awk or sed, but which uses standard python string and list methods as well as custom functions evolved to generate fast results in an intense production environment.

The following can be called with any range as parameter:

Option Explicit

Sub SetRangeBorder(poRng As Range)
    If Not poRng Is Nothing Then
        poRng.Borders(xlDiagonalDown).LineStyle = xlNone
        poRng.Borders(xlDiagonalUp).LineStyle = xlNone
        poRng.Borders(xlEdgeLeft).LineStyle = xlContinuous
        poRng.Borders(xlEdgeTop).LineStyle = xlContinuous
        poRng.Borders(xlEdgeBottom).LineStyle = xlContinuous
        poRng.Borders(xlEdgeRight).LineStyle = xlContinuous
        poRng.Borders(xlInsideVertical).LineStyle = xlContinuous
        poRng.Borders(xlInsideHorizontal).LineStyle = xlContinuous
    End If
End Sub

Examples:

Call SetRangeBorder(Range("C11"))
Call SetRangeBorder(Range("A" & result))
Call SetRangeBorder(DT.Cells(I, 6))
Call SetRangeBorder(Range("A3:I" & endRow))

When you get a connection to PostgreSQL it is always to a particular database. To access a different database, you must get a new connection.

Using \c in psql closes the old connection and acquires a new one, using the specified database and/or credentials. You get a whole new back-end process and everything.

If you don't want the hassle of using mail, you can read the mail with

cat /var/mail/<username>

and delete the mail with

sudo rm /var/mail/<username>

For myself, I just encode it in the url and use $_GET on the destination page. Here's a line as an example.

$ch = curl_init();
$this->json->p->method = "whatever";
curl_setopt($ch, CURLOPT_URL, "http://" . $_SERVER['SERVER_NAME'] . $this->json->path . '?json=' . urlencode(json_encode($this->json->p)));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

EDIT: Adding the destination snippet... (EDIT 2 added more above at OPs request)

<?php
if(!isset($_GET['json']))
    die("FAILURE");
$json = json_decode($_GET['json']);
$method = $json->method;
...
?>

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

It depends on whether you have installed Git Bash in the current user only or all users:

If it is installed on all users then put "terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe" in your User Settings (Ctrl + Comma).

If it is installed on only the current user then put "terminal.integrated.shell.windows": "C:\\Users\\<name of your user>\\AppData\\Local\\Programs\\Git\\bin\\bash.exe" in your User Settings (Ctrl + Comma).

If the methods listed above do not work then you should try Christer's solution which says -

If you want the integrated environment you need to point to the sh.exe file inside the bin folder of your Git installation.

So the configuration should say C:\\<my-git-install>\\bin\\sh.exe.

Note: The sh.exe and bash.exe appear completely same to me. There should be no difference between them.

You can have many java versions in your system.

I think you should add the java 8 in yours JREs installed or edit.

Take a look my screen:

If you click in edit (check your java 8 path):

if you get an error as Parameter 'element' implicitly has an 'any' type.Vetur(7006) in vueJs

with the error:

 exportColumns.forEach(element=> {
      if (element.command !== undefined) {
        let d = element.command.findIndex(x => x.name === "destroy");

you can fixed it by defining thoes variables as any as follow.

corrected code:

exportColumns.forEach((element: any) => {
      if (element.command !== undefined) {
        let d = element.command.findIndex((x: any) => x.name === "destroy");

BLOB primarily intended to hold non-traditional data, such as images,videos,voice or mixed media. CLOB intended to retain character-based data.

import sys
f = open(sys.argv[1] , 'r')
for line in f.readlines()[::-1]:
    print line

Please add this option:

//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,

(Reference: Chart.js)

N.B: The original solution I posted was for Highcharts, if you are not using Highcharts then please remove the tag to avoid confusion

As it is already explained in other answers, const in C merely means that a variable is read-only. It is still a run-time value. However, you can use an enum as a real constant in C:

enum { NUM_TYPES = 4 };
static int types[NUM_TYPES] = { 
  1, 2, 3, 4
};

Well what you have to "import" (use) is the namespace of MyClass not the class name itself. If both classes are in the same namespace, you don't have to "import" it.

Definition MyClass.cs

namespace Ns1
{
    public class MyClass
    {
        ...
    }
}

Usage AnotherClass.cs

using Ns1;

namespace AnotherNs
{
    public class AnotherClass
    {
        public AnotherClass()
        {
            var myInst = new MyClass();
        }
    }
}

check your value which you want to store in integer column. I think this is greater then range of integer. if you want to store value greater then integer range. you should use bigint datatype

I don't think this has been mentioned. This is like your own answer but I think it's even simpler. You can always return strings from the expressions and you can nest jsx inside expressions, so this allows for an easy to read inline expression.

HTML alone does not support this. You need to use some JS.

And also consider nowadays people use popup blocker in browsers.

If you have OS(64bit) and SSMS(64bit) and already install the AccessDatabaseEngine(64bit) and you still received an error, try this following solutions:

1: direct opening the sql server import and export wizard.

if you able to connect using direct sql server import and export wizard, then importing from SSMS is the issue, it's like activating 32bit if you import data from SSMS.

Instead of installing AccessDatabaseEngine(64bit) , try to use the AccessDatabaseEngine(32bit) , upon installation, windows will stop you for continuing the installation if you already have another app installed , if so , then use the following steps. This is from the MICROSOFT. The Quiet Installation.

If Office 365 is already installed, side by side detection will prevent the installation from proceeding. Instead perform a /quiet install of these components from command line. To do so, download the desired AccessDatabaseEngine.exe or AccessDatabaeEngine_x64.exe to your PC, open an administrative command prompt, and provide the installation path and switch Ex: C:\Files\AccessDatabaseEngine.exe /quiet

Use onClick with one of the following:

window.location.reload(), i.e.:

<button onClick="window.location.reload();">Refresh Page</button>

Or history.go(0), i.e.:

<button onClick="history.go(0);">Refresh Page</button>

Or window.location.href=window.location.href for 'full' reload, i.e.:

<button onClick="window.location.href=window.location.href">Refresh Page</button>

MDN page on the <button> element.

Go to Run (WINDOWS + R) and Type shell:startup, paste your .bat file there !

I got it to work with:

SQLiteDatabase db= this.getWritableDatabase();
        db.delete(TABLE_NAME, null, null);

Edit: This is out of date, see @Merlin's answer.

[False], being a nonempty list, is not the same as False. You should write:

test = df.sort('one', ascending=False)

You just have to hit another Graph API:

https://graph.facebook.com/me?access_token={access-token}

It will give your e-mail Id and user Id (for Facebook) also.

Kotlin solution, based on what others wrote here:

    fun isTableExists(database: SQLiteDatabase, tableName: String): Boolean {
        database.rawQuery("select DISTINCT tbl_name from sqlite_master where tbl_name = '$tableName'", null)?.use {
            return it.count > 0
        } ?: return false
    }

lets say you have a model called Book and on it a field called 'cover_pic', in that case, you can do the following to compress the image:

from PIL import Image
b = Book.objects.get(title='Into the wild')
image = Image.open(b.cover_pic.path)
image.save(b.image.path,quality=20,optimize=True)

hope it helps to anyone stumbling upon it.

When I had this issue with tf.train.string_input_producer() and tf.train.batch() initializing the local variables before I started the Coordinator solved the problem. I had been getting the error when I initialized the local variables after starting the Coordinator.

If you are grouping by some other value, then instead of what you have,

write it as

Sum(CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END) as SumSomeProduct

If, otoh, you want to group By the internal expression, (col3*col4) then

write the group By to match the expression w/o the SUM...

Select Sum(Case When col1 > col2 Then col3*col4 Else 0 End) as SumSomeProduct
From ...

Group By Case When col1 > col2 Then col3*col4 Else 0 End 

Finally, if you want to group By the actual aggregate

Select SumSomeProduct, Count(*), <other aggregate functions>
From (Select <other columns you are grouping By>, 
      Sum(Case When col1 > col2 
          Then col3*col4 Else 0 End) as SumSomeProduct
      From Table
      Group By <Other Columns> ) As Z
Group by SumSomeProduct

Using http.createServer is very low-level and really not useful for creating web applications as-is.

A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express.

When you have, you can create a basic application to handle your form:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

You can make your form point to it using:

<form action="http://127.0.0.1:8080/myaction" method="post">

The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html). You could use Express to also serve static content, like index.html, using the express.static middleware.

Try this code:

preg_match('/[a-zA-Z]+<\/a>.$/', $lastgame, $match);
print_r($match);

Using / as a delimiter means you also need to escape it here, like so: <\/a>.

UPDATE

preg_match('/<a.*<a.*>(.*)</', $lastgame, $match);
echo'['.$match[1].']';

Might not be the best way...

TL;DR - Just run this and don't disable your security:

Replace existing certs

# Windows/MacOS/Linux 
npm config set cafile "<path to your certificate file>"

# Check the 'cafile'
npm config get cafile

or extend existing certs

Set this environment variable to extend pre-defined certs: NODE_EXTRA_CA_CERTS to "<path to certificate file>"

Full story

I've had to work with npm, pip, maven etc. behind a corporate firewall under Windows - it's not fun. I'll try and keep this platform agnostic/aware where possible.

HTTP_PROXY & HTTPS_PROXY

HTTP_PROXY & HTTPS_PROXY are environment variables used by lots of software to know where your proxy is. Under Windows, lots of software also uses your OS specified proxy which is a totally different thing. That means you can have Chrome (which uses the proxy specified in your Internet Options) connecting to the URL just fine, but npm, pip, maven etc. not working because they use HTTPS_PROXY (except when they use HTTP_PROXY - see later). Normally the environment variable would look something like:

http://proxy.example.com:3128

But you're getting a 403 which suggests you're not being authenticated against your proxy. If it is basic authentication on the proxy, you'll want to set the environment variable to something of the form:

http://user:[email protected]:3128

The dreaded NTLM

There is an HTTP status code 407 (proxy authentication required), which is the more correct way of saying it's the proxy rather than the destination server that's rejecting your request. That code plagued me for the longest time until after a lot of time on Google, I learned my proxy used NTLM authentication. HTTP basic authentication wasn't enough to satisfy whatever proxy my corporate overlords had installed. I resorted to using Cntlm on my local machine (unauthenticated), then had it handle the NTLM authentication with the upstream proxy. Then I had to tell all the programs that couldn't do NTLM to use my local machine as the proxy - which is generally as simple as setting HTTP_PROXY and HTTPS_PROXY. Otherwise, for npm use (as @Agus suggests):

npm config set proxy http://proxy.example.com:3128
npm config set https-proxy http://proxy.example.com:3128

"We need to decrypt all HTTPS traffic because viruses"

After this set-up had been humming along (clunkily) for about a year, the corporate overlords decided to change the proxy. Not only that, but it would no longer use NTLM! A brave new world to be sure. But because those writers of malicious software were now delivering malware via HTTPS, the only way they could protect we poor innocent users was to man-in-the-middle every connection to scan for threats before they even reached us. As you can imagine, I was overcome with the feeling of safety.

To cut a long story short, the self-signed certificate needs to be installed into npm to avoid SELF_SIGNED_CERT_IN_CHAIN:

npm config set cafile "<path to certificate file>"

Alternatively, the NODE_EXTRA_CA_CERTS environment variable can be set to the certificate file.

I think that's everything I know about getting npm to work behind a proxy/firewall. May someone find it useful.

Edit: It's a really common suggestion to turn off HTTPS for this problem either by using an HTTP registry or setting NODE_TLS_REJECT_UNAUTHORIZED. These are not good ideas because you're opening yourself up to further man-in-the-middle or redirection attacks. A quick spoof of your DNS records on the machine doing the package installation and you'll find yourself trusting packages from anywhere. It may seem like a lot of work to make HTTPS work, but it is highly recommended. When you're the one responsible for allowing untrusted code into the company, you'll understand why.

Edit 2: Keep in mind that setting npm config set cafile <path> causes npm to only use the certs provided in that file, instead of extending the existing ones with it.

If you want to extend the existing certs (e.g. with a company cert) using the environment variable NODE_EXTRA_CA_CERTS to link to the file is the way to go and can save you a lot of hassle. See how-to-add-custom-certificate-authority-ca-to-nodejs

One can reproduce the error with the code below:

public ActionResult ClosingTheConnectionAction(){
   try
   {
      //we need to set buffer to false to
      //make sure data is written in chunks
      Response.Buffer = false;  
      var someText = "Some text here to make things happen ;-)";
      var content = GetBytes( someText );

      for(var i=0; i < 100; i++)
      {
         Response.OutputStream.Write(content, 0, content.Length);
      }

      return View();
   }
   catch(HttpException hex)
   {
      if (hex.Message.StartsWith("The remote host closed the connection. The error code is 0x800704CD."))
            {
                //react on remote host closed the connection exception.
                var msg = hex.Message;
            }  
   }
   catch(Exception somethingElseHappened)
   {
      //handle it with some other code
   }

   return View();
} 

Now run the website in debug mode. Put a breakpoint in the loop that writes to the output stream. Go to that action method and after the first iteration passed close the tab of the browser. Hit F10 to continue the loop. After it hit the next iteration you will see the exception. Enjoy your exception :-)

I'm a little late, and I'm not sure if this is what you're looking for, but I thought I'd add it just in case someone else finds it useful.

Suppose this is your file structure:

/BulutDepoProject
    /bin
        Main.exe
    /FolderIcon
        Folder.ico
        Main.cs

You need to write your path relative to the Main.exe file. So, you want to access Folder.ico, in your Main.cs you can use:

String path = "..\\FolderIcon\\Folder.ico"

That seemed to work for me!

You can also use the Elvis operator:

arr = ['Bob', 'charley', 'fudge', 'Fudge', 'biscuit'];
arr.sort(function(s1, s2){
    var l=s1.toLowerCase(), m=s2.toLowerCase();
    return l===m?0:l>m?1:-1;
});
console.log(arr);

Gives:

biscuit,Bob,charley,fudge,Fudge

The localeCompare method is probably fine though...

Note: The Elvis operator is a short form 'ternary operator' for if then else, usually with assignment.
If you look at the ?: sideways, it looks like Elvis...
i.e. instead of:

if (y) {
  x = 1;
} else {
  x = 2;
}

you can use:

x = y?1:2;

i.e. when y is true, then return 1 (for assignment to x), otherwise return 2 (for assignment to x).

Or no float conversion at all by just specifying floats in the list.

l = [-1.2, 0.0, 1]
x = min(l)

or

l = min([-1.2, 0.0, 1])

As this is quite popular question that deals with live-editing of JS, I want to point out another useful option. As described by svjacob in his answer:

I realized I could attach a break-point in the debugger to some line of code before what I wanted to dynamically edit. And since break-points stay even after a reload of the page, I was able to edit the changes I wanted while paused at break-point and then continued to let the page load.

The above solution didn't work for me for quite large JS (webpack bundle - 3.21MB minified version, 130k lines of code in prettified version) - chrome crashed and asked for page reloading which reverted any saved changes. The way to go in this case was Fiddler where you can set AutoRespond option to replace any remote resource with any local file from your computer - see this SO question for details.

In my case I also had to add CORS headers to fiddler to successfully mock response.

I suggest to use Java 8 Lambda approach:

List<Report> reportList = new ArrayList<Report>();
reportList.sort(Comparator.comparing(Report::getRecord1).thenComparing(Report::getRecord2));

VAR=$(scan)

Exactly the same way as for programs.

If your website also on the oxfordlearnersdictionaries.com domain, USE the following into the oxfordlearnersdictionaries.com .htaccess file:

Header set Access-Control-Allow-Origin "*"

Here's a simple small function that can be applied anywhere as long as you're using jQuery.

var redirect = 'http://www.website.com/page?id=23231';
$.redirectPost(redirect, {x: 'example', y: 'abc'});

// jquery extend function
$.extend(
{
    redirectPost: function(location, args)
    {
        var form = '';
        $.each( args, function( key, value ) {
            form += '<input type="hidden" name="'+key+'" value="'+value+'">';
        });
        $('<form action="'+location+'" method="POST">'+form+'</form>').appendTo('body').submit();
    }
});

Per the comments, I have expanded upon my answer:

// jquery extend function
$.extend(
{
    redirectPost: function(location, args)
    {
        var form = $('<form></form>');
        form.attr("method", "post");
        form.attr("action", location);

        $.each( args, function( key, value ) {
            var field = $('<input></input>');

            field.attr("type", "hidden");
            field.attr("name", key);
            field.attr("value", value);

        });
        $(form).appendTo('body').submit();
    }

I use both PuTTY and Bitvise SSH Client. PuTTY handles screen sessions better, but Bitvise automatically opens up a SFTP window so you can transfer files just like you would with an FTP client.

You can replace the items at specific position using set method of ArrayList as below:

list.set( your_index, your_item );

But the element should be present at the index you are passing inside set() method else it will throw exception.

1. Open Google Chrome.
2. Click Menu on the upper right side. Beside the STAR symbol (Bookmark).
3. Click Show Advanced Settings.
4. Scroll down and find Network.
5. Click Change proxy settings.
6. On the Connections tab, click LAN settings.
7. Uncheck "Use a proxy server for your LAN."
8. Then click OK.

Hope it helps .

Hope this helps you.

Thanks, I could not used the page directive because I have to set a different content type according to some URL parameter. I will paste my code here since it's something quite common with JSON:

    <%
        String callback = request.getParameter("callback");
        response.setCharacterEncoding("UTF-8");
        if (callback != null) {
            // Equivalent to: <@page contentType="text/javascript" pageEncoding="UTF-8">
            response.setContentType("text/javascript");
        } else {
            // Equivalent to: <@page contentType="application/json" pageEncoding="UTF-8">
            response.setContentType("application/json");
        }

        [...]

        String output = "";

        if (callback != null) {
            output += callback + "(";
        }

        output += jsonObj.toString();

        if (callback != null) {
            output += ");";
        }
    %>
    <%=output %>

When callback is supplied, returns:

    callback({...JSON stuff...});

with content-type "text/javascript"

When callback is NOT supplied, returns:

    {...JSON stuff...}

with content-type "application/json"

use mode1.name() or String.valueOf(Modes.mode1)

please try following to generate

 function addRow()
    {
        var e1 = document.createElement("input");
        e1.type = "text";
        e1.name = "name1";

        var cont = document.getElementById("content")
        cont.appendChild(e1);

    }

Yes. add a linked server entry, and use select into using the four part db object naming convention.

Example:

SELECT * INTO targetTable 
FROM [sourceserver].[sourcedatabase].[dbo].[sourceTable]

Your server process has received a SIGPIPE writing to a socket. This usually happens when you write to a socket fully closed on the other (client) side. This might be happening when a client program doesn't wait till all the data from the server is received and simply closes a socket (using close function).

In a C program you would normally try setting to ignore SIGPIPE signal or setting a dummy signal handler for it. In this case a simple error will be returned when writing to a closed socket. In your case a python seems to throw an exception that can be handled as a premature disconnect of the client.

You can install the version you need easily:

First get source:

$ wget https://ftp.gnu.org/gnu/automake/automake-1.15.tar.gz

Unpack it:

$ tar -xzvf automake-1.15.tar.gz

Build and install:

$ cd automake-1.15
$ ./configure  --prefix=/opt/aclocal-1.15
$ make
$ sudo mkdir -p /opt
$ sudo make install

Use it:

$ export PATH=/opt/aclocal-1.15/bin:$PATH
$ aclocal --version

aclocal (GNU automake) 1.15

Now when aclocal is called, you get the right version.

I just found the same issue with Aliases on a Windows install of Xampp.

To solve the 403 error:

<Directory "C:/Your/Directory/With/No/Trailing/Slash">
   Require all granted
</Directory>

Alias /dev "C:/Your/Directory/With/No/Trailing/Slash"

The default Xampp set up should be fine with just this. Some people have experienced issues with a deny placed on the root directory so flipping out the directory tag to:

<Directory "C:/Your/Directory/With/No/Trailing/Slash">
   Allow from all
   Require all granted
</Directory>

Would help with this but the current version of Xampp (v1.8.1 at the time of writing) doesn't require it.

As for op's issue with port 80 Xampp includes a handy Netstat button to discover what's using your ports. Fire that off and fix the conflict, I imagine it could have been IIS but can't be sure.

The primary consumers of these properties are user agents such as screen readers for blind people. So in the case with a Bootstrap modal, the modal's div has role="dialog". When the screen reader notices that a div becomes visible which has this role, it'll speak the label for that div.

There are lots of ways to label things (and a few new ones with ARIA), but in some cases it is appropriate to use an existing element as a label (semantic) without using the <label> HTML tag. With HTML modals the label is usually a <h> header. So in the Bootstrap modal case, you add aria-labelledby=[IDofModalHeader], and the screen reader will speak that header when the modal appears.

Generally speaking a screen reader is going to notice whenever DOM elements become visible or invisible, so the aria-hidden property is frequently redundant and can probably be skipped in most cases.

If you are using Docker Compose then this will take you inside a Docker container.

docker-compose run container_name /bin/bash

Inside the container it will take you to WORKDIR defined in the Dockerfile. You can change your work directory by

WORKDIR directory_path # E.g  /usr/src -> container's path

Plugins -> Plugin Manager -> Show Plugin Manager -> Setting -> Check mark On Force HTTP instead of HTTPS for downloading Plugin List & Use development plugin list (may contain untested, unvalidated or un-installable plugins). -> OK.

If you want to echo all days between the start and end date, I came up with this :

$startdatum = $_POST['start']; // starting date
$einddatum = $_POST['eind']; // end date

$now = strtotime($startdatum);
$your_date = strtotime($einddatum);
$datediff = $your_date - $now;
$number = floor($datediff/(60*60*24));

for($i=0;$i <= $number; $i++)
{
    echo date('d-m-Y' ,strtotime("+".$i." day"))."<br>";
}

If you are helpless like me, try this:

List all Sub-Modules of "Serial" (or whatever package you are having trouble with) with the method described here: List all the modules that are part of a python package

In my case, the problems solved one after the other.

...looks like a bug to me...

char name[10][10]
int i,j,n;//here "n" is number of enteries
printf("\nEnter size of array = ");
scanf("%d",&n);
for(i=0;i<n;i++)
{
    for(j=0;j<1;j++)
    {
        printf("\nEnter name = ");
        scanf("%s",&name[i]);
    }
}
//printing the data
for(i=0;i<n;i++)
{
    for(j=0;j<1;j++)
    {
        printf("%d\t|\t%s\t|\t%s",rollno[i][j],name[i],sex[i]);
    }
    printf("\n");
}

Here try this!!!

I've tried both design strategies - nested and non-nested endpoints. I've found that:

1. if the nested resource has a primary key and you don't have its parent primary key, the nested structure requires you to get it, even though the system doesn't actually require it.

2. nested endpoints typically require redundant endpoints. In other words, you will more often than not, need the additional /employees endpoint so you can get a list of employees across departments. If you have /employees, what exactly does /companies/departments/employees buy you?

3. nesting endpoints don't evolve as nicely. E.g. you might not need to search for employees now but you might later and if you have a nested structure, you have no choice but to add another endpoint. With a non-nested design, you just add more parameters, which is simpler.

4. sometimes a resource could have multiple types of parents. Resulting in multiple endpoints all returning the same resource.

5. redundant endpoints makes the docs harder to write and also makes the api harder to learn.

In short, the non-nested design seems to allow a more flexible and simpler endpoint schema.

I followed the db.dropDatabase() route for a long time, however if you're trying to use this for wiping the database in between test cases you may eventually find problems with index constraints not being honored after the database drop. As a result, you'll either need to mess about with ensureIndexes, or a simpler route would be avoiding the dropDatabase alltogether and just removing from each collection in a loop such as:

db.getCollectionNames().forEach(
  function(collection_name) {
    db[collection_name].remove()
  }
);

In my case I was running this from the command-line using:

mongo [database] --eval "db.getCollectionNames().forEach(function(n){db[n].remove()});"

Linux / Ubuntu: If installed phpmyadmin via apt: sudo apt-get install phpmyadmin php-mbstring

Can check /etc/phpmyadmin/config-db.php for changing the user credentials.

$dbuser='pma';
$dbpass='my_pass';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='3306';
$dbtype='mysql';

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

I found this very useful: create as many threads as cores and let them execute a (large) number of tasks (in this case, calling a shell program):

import Queue
import threading
import multiprocessing
import subprocess

q = Queue.Queue()
for i in range(30): # Put 30 tasks in the queue
    q.put(i)

def worker():
    while True:
        item = q.get()
        # Execute a task: call a shell program and wait until it completes
        subprocess.call("echo " + str(item), shell=True)
        q.task_done()

cpus = multiprocessing.cpu_count() # Detect number of cores
print("Creating %d threads" % cpus)
for i in range(cpus):
     t = threading.Thread(target=worker)
     t.daemon = True
     t.start()

q.join() # Block until all tasks are done

What about doing like this.

JSON.stringify({}) === "{}"

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

What is this warning about?

Modern CPUs provide a lot of low-level instructions, besides the usual arithmetic and logic, known as extensions, e.g. SSE2, SSE4, AVX, etc. From the Wikipedia:

Advanced Vector Extensions (AVX) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008 and first supported by Intel with the Sandy Bridge processor shipping in Q1 2011 and later on by AMD with the Bulldozer processor shipping in Q3 2011. AVX provides new features, new instructions and a new coding scheme.

In particular, AVX introduces fused multiply-accumulate (FMA) operations, which speed up linear algebra computation, namely dot-product, matrix multiply, convolution, etc. Almost every machine-learning training involves a great deal of these operations, hence will be faster on a CPU that supports AVX and FMA (up to 300%). The warning states that your CPU does support AVX (hooray!).

I'd like to stress here: it's all about CPU only.

Why isn't it used then?

Because tensorflow default distribution is built without CPU extensions, such as SSE4.1, SSE4.2, AVX, AVX2, FMA, etc. The default builds (ones from pip install tensorflow) are intended to be compatible with as many CPUs as possible. Another argument is that even with these extensions CPU is a lot slower than a GPU, and it's expected for medium- and large-scale machine-learning training to be performed on a GPU.

What should you do?

If you have a GPU, you shouldn't care about AVX support, because most expensive ops will be dispatched on a GPU device (unless explicitly set not to). In this case, you can simply ignore this warning by

# Just disables the warning, doesn't take advantage of AVX/FMA to run faster
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'

... or by setting export TF_CPP_MIN_LOG_LEVEL=2 if you're on Unix. Tensorflow is working fine anyway, but you won't see these annoying warnings.

If you don't have a GPU and want to utilize CPU as much as possible, you should build tensorflow from the source optimized for your CPU with AVX, AVX2, and FMA enabled if your CPU supports them. It's been discussed in this question and also this GitHub issue. Tensorflow uses an ad-hoc build system called bazel and building it is not that trivial, but is certainly doable. After this, not only will the warning disappear, tensorflow performance should also improve.

Use memcpy in C, std::copy in C++.

The standard approach is to use the select module.

However, this doesn't work on Windows. For that, you can use the msvcrt module's keyboard polling.

Often, this is done with multiple threads -- one per device being "watched" plus the background processes that might need to be interrupted by the device.

The problem with other answers here is that they use position: absolute;

This makes it difficult to layout the element itself in relation to the ::before pseudo-element. For example, if you wish to show an image before a link like this:

Here's how I was able to achieve the layout in the picture:

a::before {_x000D_
  content: "";_x000D_
  float: left;_x000D_
  width: 16px;_x000D_
  height: 16px;_x000D_
  margin-right: 5px;_x000D_
  background: url(../../lhsMenu/images/internal_link.png) no-repeat 0 0;_x000D_
  background-size: 80%;_x000D_
}

Note that this method allows you to scale the background image, as well as keep the ability to use margins and padding for layout.

For people who find this via search engines, you do not need VBA. You can just:

1.) select the query or table with your mouse
2.) click export data from the ribbon
3.) click excel from the export subgroup
4.) follow the wizard to select the output file and location.

You can add a comment to an MSAccess query as follows: Create a dummy field in the query. Not elegant but is self-documentating and contained in the query, which makes cheking it into source code control alot more feasible! Jere's an example. Go into SQL view and add the dummy field (you can do from design view too):

SELECT  "2011-01-21;JTR;Added FIELD02;;2011-01-20;JTR;Added qryHISTORY;;" as qryHISTORY,  ...rest of query here...

Run the query:

qryHISTORY                           FIELD01 FIELD02 ...
2011-01-21;JTR;Added FIELD02;;2011-01-20;JTR;Added qryHISTORY;;"  0000001  ABCDEF ...

Note the use of ";" as field delimiter in qryHISTORY field, and ";;" as an end of comment, and use of ISO date format and intials, as well as comment. Have tested this with up to 646 characters in the qryHISTORY field.

ThreeTenABP and java.time

Here’s the modern answer. When this question was asked in 2011, Calendar and GregorianCalendar were commonly used for dates and times even though they were always poorly designed. That’s 8 years ago now, and those classes are long outdated. Assuming you are not yet on API level 26, my suggestion is to use the ThreeTenABP library, which contains an Android adapted backport of java.time, the modern Java date and time API. java.time is so much nicer to work with.

Depending on your exact needs and situation there are two options:

1. Use Month and its getDisplayName method.
2. Use a DateTimeFormatter.

Use Month

    Locale desiredLanguage = Locale.ENGLISH;
    Month m = Month.MAY;
    String monthName = m.getDisplayName(TextStyle.FULL, desiredLanguage);
    System.out.println(monthName);

Output from this snippet is:

May

In a few languages it will make a difference whether you use TextStyle.FULL or TextStyle.FULL_STANDALONE. You will have to see, maybe check with your users, which of the two fits into your context.

Use a DateTimeFormatter

If you’ve got a date with or without time of day, I find a DateTimeFormatter more practical. For example:

    DateTimeFormatter monthFormatter = DateTimeFormatter.ofPattern("MMMM", desiredLanguage);

    ZonedDateTime dateTime = ZonedDateTime.of(2019, 5, 31, 23, 49, 51, 0, ZoneId.of("America/Araguaina"));
    String monthName = dateTime.format(monthFormatter);

I am showing the use of a ZonedDateTime, the closest replacement for the old Calendar class. The above code will work for a LocalDate, a LocalDateTime, MonthDay, OffsetDateTime and a YearMonth too.

What if you got a Calendar from a legacy API not yet upgraded to java.time? Convert to a ZonedDateTime and proceed as above:

    Calendar c = getCalendarFromLegacyApi();
    ZonedDateTime dateTime = DateTimeUtils.toZonedDateTime(c);

The rest is the same as before.

Question: Doesn’t java.time require Android API level 26?

java.time works nicely on both older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In non-Android Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

The answer is that you have to use TableRow.LayoutParams, not LinearLayout.LayoutParams or any other LayoutParams.

TextView tv = new TextView(v.getContext());
LayoutParams params = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
tv.setLayoutParams(params);

The different LayoutParams are not interchangeable and if you use the wrong one then nothing seems to happen. The text view's parent is a table row, hence:

            var currentLink = $("nav ul li a[href='" + pathName + "']");
            currentLink.addClass("active");
        }
    }
    setSelectedPageNav();

Maybe the file is corrupt - this has happened to me several times before and the only solution is to copy everything out into a new file.

Please can you try the following:

• Save a new xlsm file and call it "MyFullyQualified.xlsm"
• Add a sheet with no protection and call it "mySheet"
• Add a module to the workbook and add the following procedure

Does this run?

 Sub varchanger()

 With Excel.Application
    .ScreenUpdating = True
    .Calculation = Excel.xlCalculationAutomatic
    .EnableEvents = True
 End With

 On Error GoTo Whoa:

    Dim myBook As Excel.Workbook
    Dim mySheet As Excel.Worksheet
    Dim Rng  As Excel.Range

    Set myBook = Excel.Workbooks("MyFullyQualified.xlsm")
    Set mySheet = myBook.Worksheets("mySheet")
    Set Rng = mySheet.Range("A1")

    'ActiveSheet.Unprotect


    Rng.Value = "SubTotal"

    Excel.Workbooks("MyFullyQualified.xlsm").Worksheets("mySheet").Range("A1").Value = "Asdf"

Based off Simon McKenzie's answer to this question, I'd suggest using a pair of methods like this:

    public static void ZipFolder(string sourceFolder, string zipFile)
    {
        if (!System.IO.Directory.Exists(sourceFolder))
            throw new ArgumentException("sourceDirectory");

        byte[] zipHeader = new byte[] { 80, 75, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

        using (System.IO.FileStream fs = System.IO.File.Create(zipFile))
        {
            fs.Write(zipHeader, 0, zipHeader.Length);
        }

        dynamic shellApplication = Activator.CreateInstance(Type.GetTypeFromProgID("Shell.Application"));
        dynamic source = shellApplication.NameSpace(sourceFolder);
        dynamic destination = shellApplication.NameSpace(zipFile);

        destination.CopyHere(source.Items(), 20);
    }

    public static void UnzipFile(string zipFile, string targetFolder)
    {
        if (!System.IO.Directory.Exists(targetFolder))
            System.IO.Directory.CreateDirectory(targetFolder);

        dynamic shellApplication = Activator.CreateInstance(Type.GetTypeFromProgID("Shell.Application"));
        dynamic compressedFolderContents = shellApplication.NameSpace(zipFile).Items;
        dynamic destinationFolder = shellApplication.NameSpace(targetFolder);

        destinationFolder.CopyHere(compressedFolderContents);
    }
}

Here is a well tested function which i used for my projects with detailed self explanatory comments

There are many times when the ports other than 80 are blocked by server firewall so the code appears to be working fine on localhost but not on the server

function get_page($url){

global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding

$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}

you can simply cast a string array to int array by:

var converted = arr.Select(int.Parse)

I've used encodeURIComponent() and decodeURIComponent() too.

Your question implies that you don't need Unicode. Try the following code snippet; if it works for you, you're done:

Python 2.5.2 (r252:60911, Aug 22 2008, 02:34:17)
[GCC 4.3.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale
>>> locale.setlocale(locale.LC_COLLATE, "en_US")
'en_US'
>>> sorted("ABCabc", key=locale.strxfrm)
['a', 'A', 'b', 'B', 'c', 'C']
>>> sorted("ABCabc", cmp=locale.strcoll)
['a', 'A', 'b', 'B', 'c', 'C']

Clarification: in case it is not obvious at first sight, locale.strcoll seems to be the function you need, avoiding the str.lower or locale.strxfrm "duplicate" strings.

I modified Vadim's solution with the following:

####################################################################
# Bash v3 does not support associative arrays
# and we cannot use ksh since all generic scripts are on bash
# Usage: map_put map_name key value
#
function map_put
{
    alias "${1}$2"="$3"
}

# map_get map_name key
# @return value
#
function map_get {
    if type -p "${1}$2"
        then
            alias "${1}$2" | awk -F "'" '{ print $2; }';
    fi
}

# map_keys map_name 
# @return map keys
#
function map_keys
{
    alias -p | grep $1 | cut -d'=' -f1 | awk -F"$1" '{print $2; }'
}

The change is to map_get in order to prevent it from returning errors if you request a key that doesn't exist, though the side-effect is that it will also silently ignore missing maps, but it suited my use-case better since I just wanted to check for a key in order to skip items in a loop.

The core of the answer lies on finding the next element:

  function findNextTabStop(el) {
    var universe = document.querySelectorAll('input, button, select, textarea, a[href]');
    var list = Array.prototype.filter.call(universe, function(item) {return item.tabIndex >= "0"});
    var index = list.indexOf(el);
    return list[index + 1] || list[0];
  }

Usage:

var nextEl = findNextTabStop(element);
nextEl.focus();

Notice I don't care about prioritizing tabIndex.

If you've ever been saved by an Emacs backup file, you probably want more of them, not less of them. It is annoying that they go in the same directory as the file you're editing, but that is easy to change. You can make all backup files go into a directory by putting something like the following in your .emacs.

(setq backup-directory-alist `(("." . "~/.saves")))

There are a number of arcane details associated with how Emacs might create your backup files. Should it rename the original and write out the edited buffer? What if the original is linked? In general, the safest but slowest bet is to always make backups by copying.

(setq backup-by-copying t)

If that's too slow for some reason you might also have a look at backup-by-copying-when-linked.

Since your backups are all in their own place now, you might want more of them, rather than less of them. Have a look at the Emacs documentation for these variables (with C-h v).

(setq delete-old-versions t
  kept-new-versions 6
  kept-old-versions 2
  version-control t)

Finally, if you absolutely must have no backup files:

(setq make-backup-files nil)

It makes me sick to think of it though.

It looks like psexec -h is the way to do this:

 -h         If the target system is Windows Vista or higher, has the process
            run with the account's elevated token, if available.

Which... doesn't seem to be listed in the online documentation in Sysinternals - PsExec.

But it works on my machine.

//Save
NSUserDefaults.standardUserDefaults().setObject("yourString", forKey: "YourStringKey")

//retrive
let yourStr : AnyObject? = NSUserDefaults.standardUserDefaults().objectForKey("YourStringKey")

If the original size is 100 x 100 and you want to scale it to 50 x 50, use scaledSize instead of Size.

var icon = {
    url: "../res/sit_marron.png", // url
    scaledSize: new google.maps.Size(50, 50), // scaled size
    origin: new google.maps.Point(0,0), // origin
    anchor: new google.maps.Point(0, 0) // anchor
};

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(lat, lng),
    map: map,
    icon: icon
});

Set texts with different sizes and styles, and size and style for texts from cells ( with Range)

Sub EmailManuellAbsenden()

Dim ghApp As Object
Dim ghOldBody As String

Set ghApp = CreateObject("Outlook.Application")
With ghApp.CreateItem(0)
.To = Range("B2")
.CC = Range("B3")
.Subject = Range("B4")
.GetInspector.Display
 ghOldBody = .htmlBody

 ghNewBody = "<font style=""font-family: Calibri; font-size: 11pt;""/font>" & _
 "<font style=""font-family: Arial; font-size: 14pt;"">Arial Text 14</font>" & _
 Range("B5") & "<br>" & _
 Range("B6") & "<br>" & _
 "<font style=""font-family: Chiller; font-size: 21pt;"">Ciller 21</font>" &
 Range("B5")
 .htmlBody = ghNewBody & ghOldBody

 End With

End Sub
'Fill B2 to B6 with some letters for testing
'"<font style=""font-family: Calibri; font-size: 15pt;""/font>" = works for all Range Objekts

For several cases, or even just a few cases involving a lot of criteria, consider using a switch.

switch( true ){

    case ( !empty($youtube) && !empty($link) ):{
        // Nothing is empty...
        break;
    }

    case ( !empty($youtube) && empty($link) ):{
        // One is empty...
        break;
    }

    case ( empty($youtube) && !empty($link) ):{
        // The other is empty...
        break;
    }

    case ( empty($youtube) && empty($link) ):{
        // Everything is empty
        break;
    }

    default:{
        // Even if you don't expect ever to use it, it's a good idea to ALWAYS have a default.
        // That way if you change it, or miss a case, you have some default handler.
        break;
    }

}

If you have multiple cases that require the same action, you can stack them and omit the break; to flowthrough. Just maybe put a comment like /*Flowing through*/ so you're explicit about doing it on purpose.

Note that the { } around the cases aren't required, but they are nice for readability and code folding.

More about switch: http://php.net/manual/en/control-structures.switch.php

install -d -m 0777 /your/dir

should give you what you want. Be aware that every user has the right to write add and delete files in that directory.

Create a new immutable map:

scala> val m1 = Map("k0" -> "v0")   
m1: scala.collection.immutable.Map[String,String] = Map(k0 -> v0)

Add a new key/value pair to the above map (and create a new map, since they're both immutable):

scala> val m2 = m1 + ("k1" -> "v1")             
m2: scala.collection.immutable.Map[String,String] = Map(k0 -> v0, k1 -> v1)

Make the area with your data and formulas a Table:

Then adding new information in the next line will copy all formulas in that table for the new line. Data validation will also be applied for the new row as it was for the whole column. This is indeed Excel being smarter with your data.

NO VBA required...

You're looking for the File, StreamWriter, and StreamReader classes.

I will refer you to my blog post - A lesson in address storage, I go into some of the techniques and algorithms used in the process of address validation. My key thought is "Don't be lazy with address storage, it will cause you nothing but headaches in the future!"

Also, there is another StackOverflow question that asks this question. Entitled How should international geographic addresses be stored in a relational database.

In PHP you can use:

$page = $_SERVER['PHP_SELF'];
$sec = "10";
header("Refresh: $sec; url=$page");

Or just use JavaScript's window.location.reload().

Going to add my answer to the list, since NONE of these fixed my problem. I ended up wrapping my content in a div, giving that div a class, and specifying the min-width on the div, AND specifying the maxWidth on the infoWindow, AND they both needed to be the same size, otherwise either the width or the height would be overflowing on boxes with just the wrong amount of content.

Javascript:

// Set up the content for the info box
var content = "<div class='infowindow-content'>" + content + "</div>";

// create a map info box
var infoWindow = new google.maps.InfoWindow({
    maxWidth: 350,
    content: content
});

CSS:

div.infowindow-content {
    min-width: 350px;
}

In <body> you should have two <script> tags:

<script src="https://code.jquery.com/jquery-2.1.3.js"></script>
<script src="js/bootstrap.js"></script>

The first one will load jQuery from the CDN, and second one will load Bootstrap's Javascript from a local directory (in this case it's a directory called js).

The question does not make clear what exactly you want to achieve.

List has the append method, which appends its argument to the list:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.append(list_two)
>>> list_one
[1, 2, 3, [4, 5, 6]]

There's also the extend method, which appends items from the list you pass as an argument:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.extend(list_two)
>>> list_one
[1, 2, 3, 4, 5, 6]

And of course, there's the insert method which acts similarly to append but allows you to specify the insertion point:

>>> list_one.insert(2, list_two)
>>> list_one
[1, 2, [4, 5, 6], 3, 4, 5, 6]

To extend a list at a specific insertion point you can use list slicing (thanks, @florisla):

>>> l = [1, 2, 3, 4, 5]
>>> l[2:2] = ['a', 'b', 'c']
>>> l
[1, 2, 'a', 'b', 'c', 3, 4, 5]

List slicing is quite flexible as it allows to replace a range of entries in a list with a range of entries from another list:

>>> l = [1, 2, 3, 4, 5]
>>> l[2:4] = ['a', 'b', 'c'][1:3]
>>> l
[1, 2, 'b', 'c', 5]

Here you go

var yourString = "/installers/";_x000D_
var result = yourString.substring(1, yourString.length-1);_x000D_
_x000D_
console.log(result);

Or you can use .slice as suggested by Ankit Gupta

var yourString = "/installers/services/";_x000D_
_x000D_
var result = yourString.slice(1,-1);_x000D_
_x000D_
console.log(result);

Documentation for the slice and substring.

As Chris suggests, you can do it like this:

public string GetXMLAsString(XmlDocument myxml)
{
    return myxml.OuterXml;
}

Or like this:

public string GetXMLAsString(XmlDocument myxml)
    {

        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        myxml.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

and if you really want to create a new XmlDocument then do this

XmlDocument newxmlDoc= myxml

@($output).Count does not always produce correct results. I used the ($output | Measure).Count method.

I found this with VMware Get-VmQuestion cmdlet:

$output = Get-VmQuestion -VM vm1
@($output).Count

The answer it gave is one, whereas

$output

produced no output (the correct answer was 0 as produced with the Measure method).

This only seemed to be the case with 0 and 1. Anything above 1 was correct with limited testing.

For any Windows users still having this issue, this is what fixed it for me:

1. Run where create-react-app to get the path (mine was in C:\Users\username\AppData\Local\Yarn\bin).
2. Navigate to that directory and delete both "create-react-app" and "create-react-app.cmd".
3. Navigate to the directory you want to start a project in.
4. Run npm install create-react-app, npx create-react-app name-of-app, cd name-of-app, yarn start.

Step #4 will vary based on your configuration, but that's just what got me up and running.

wrapped in a function:

function remove_rows(tablename) { 
    $(tablename).find("tr:gt(0)").remove();        
}

then call it:

remove_rows('#table1');
remove_rows('#table2');

Use:

docker inspect -f "{{.Path}} {{.Args}} ({{.Id}})" $(docker ps -a -q)

That will display the command path and arguments, similar to docker ps.

Ben is right. I also can't think of any way to do this. I'd suggest either the method Ben recommends, or the following to strip the Workbook name off.

Dim cell As Range
Dim address As String
Set cell = Worksheets(1).Cells.Range("A1")
address = cell.address(External:=True)
address = Right(address, Len(address) - InStr(1, address, "]"))

Add overflow: auto to the container div. http://www.quirksmode.org/css/clearing.html This website shows a few options when having this issue.

With booleans, there is no output difference between the two. You can swap && and & or || and | and it will never change the result of your expression.

The difference lies behind the scene where the information is being processed. When you right an expression "(a != 0) & ( b != 0)" for a= 0 and b = 1, The following happens:

left side: a != 0 --> false
right side: b 1= 0 --> true
left side and right side are both true? --> false
expression returns false

When you write an expression (a != 0) && ( b != 0) when a= 0 and b = 1, the following happens:

a != 0 -->false
expression returns false

Less steps, less processing, better coding, especially when doing many boolean expression or complicated arguments.

Here is the sequence that worked for me after struggling for several hours:

Assume the bot name is my_bot.

1- Add the bot to the group.
Go to the group, click on group name, click on Add members, in the searchbox search for your bot like this: @my_bot, select your bot and click add.

2- Send a dummy message to the bot.
You can use this example: /my_id @my_bot
(I tried a few messages, not all the messages work. The example above works fine. Maybe the message should start with /)

3- Go to following url: https://api.telegram.org/botXXX:YYYY/getUpdates
replace XXX:YYYY with your bot token

4- Look for "chat":{"id":-zzzzzzzzzz,
-zzzzzzzzzz is your chat id (with the negative sign).

5- Testing: You can test sending a message to the group with a curl:

curl -X POST "https://api.telegram.org/botXXX:YYYY/sendMessage" -d "chat_id=-zzzzzzzzzz&text=my sample text"

If you miss step 2, there would be no update for the group you are looking for. Also if there are multiple groups, you can look for the group name in the response ("title":"group_name").

Hope this helps.

I've seen this anti-pattern from people who don't quite get the & address-of operator. If they need to call a function with a pointer, they'll always allocate on the heap so they get a pointer.

void FeedTheDog(Dog* hungryDog);

Dog* badDog = new Dog;
FeedTheDog(badDog);
delete badDog;

Dog goodDog;
FeedTheDog(&goodDog);

To display HTML tags within a browser, surround the output with < xmp> and < / xmp> tags

For Swift 5, it also can load css.

extension String {
    public var convertHtmlToNSAttributedString: NSAttributedString? {
        guard let data = data(using: .utf8) else {
            return nil
        }
        do {
            return try NSAttributedString(data: data,options: [.documentType: NSAttributedString.DocumentType.html,.characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil)
        }
        catch {
            print(error.localizedDescription)
            return nil
        }
    }

    public func convertHtmlToAttributedStringWithCSS(font: UIFont? , csscolor: String , lineheight: Int, csstextalign: String) -> NSAttributedString? {
        guard let font = font else {
            return convertHtmlToNSAttributedString
        }
        let modifiedString = "<style>body{font-family: '\(font.fontName)'; font-size:\(font.pointSize)px; color: \(csscolor); line-height: \(lineheight)px; text-align: \(csstextalign); }</style>\(self)";
        guard let data = modifiedString.data(using: .utf8) else {
            return nil
        }
        do {
            return try NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil)
        }
        catch {
            print(error)
            return nil
        }
    }
}

After that, go to your string you want to convert to NSAttributedString and place it like the example below:

myUILabel.attributedText = "Swift is awesome!!!".convertHtmlToAttributedStringWithCSS(font: UIFont(name: "Arial", size: 16), csscolor: "black", lineheight: 5, csstextalign: "center")

Here’s what every parameter takes:

• font: Add your font as usually do in a UILabel/UITextView, using UIFont with the name of your custom font and the size.
• csscolor: Either add color in HEX format, like "#000000" or use the name of the color, like "black".
• lineheight: It’s the space between the lines when you have multiple lines in a UILabel/UITextView.
• csstextalign: It’s the alignment of the text, the value that you need to add is "left" or "right" or "center" or "justify"

A proper benchmark or how the number may lie

Following the argument about Math.ceil(value/10d) and (value+9)/10 I ended up coding a proper non-dead code, non-interpret mode benchmark. I've been telling that writing micro benchmark is not an easy task. The code below illustrates this:

00:21:40.109 starting up....
00:21:40.140 doubleCeil: 19444599
00:21:40.140 integerCeil: 19444599
00:21:40.140 warming up...
00:21:44.375 warmup doubleCeil: 194445990000
00:21:44.625 warmup integerCeil: 194445990000
00:22:27.437 exec doubleCeil: 1944459900000, elapsed: 42.806s
00:22:29.796 exec integerCeil: 1944459900000, elapsed: 2.363s

The benchmark is in Java since I know well how Hotspot optimizes and ensures it's a fair result. With such results, no statistics, noise or anything can taint it.

Integer ceil is insanely much faster.

The code

package t1;

import java.math.BigDecimal;

import java.util.Random;

public class Div {
    static int[] vals;

    static long doubleCeil(){
        int[] v= vals;
        long sum = 0;
        for (int i=0;i<v.length;i++){
            int value = v[i];
            sum+=Math.ceil(value/10d);
        }
        return sum;
    }

    static long integerCeil(){      
        int[] v= vals;
        long sum = 0;
        for (int i=0;i<v.length;i++){
            int value = v[i];
            sum+=(value+9)/10;
        }
        return sum;     
    }

    public static void main(String[] args) {
        vals = new  int[7000];
        Random r= new Random(77);
        for (int i = 0; i < vals.length; i++) {
            vals[i] = r.nextInt(55555);
        }
        log("starting up....");

        log("doubleCeil: %d", doubleCeil());
        log("integerCeil: %d", integerCeil());
        log("warming up...");       

        final int warmupCount = (int) 1e4;
        log("warmup doubleCeil: %d", execDoubleCeil(warmupCount));
        log("warmup integerCeil: %d", execIntegerCeil(warmupCount));

        final int execCount = (int) 1e5;

        {       
        long time = System.nanoTime();
        long s = execDoubleCeil(execCount);
        long elapsed = System.nanoTime() - time;
        log("exec doubleCeil: %d, elapsed: %.3fs",  s, BigDecimal.valueOf(elapsed, 9));
        }

        {
        long time = System.nanoTime();
        long s = execIntegerCeil(execCount);
        long elapsed = System.nanoTime() - time;
        log("exec integerCeil: %d, elapsed: %.3fs",  s, BigDecimal.valueOf(elapsed, 9));            
        }
    }

    static long execDoubleCeil(int count){
        long sum = 0;
        for(int i=0;i<count;i++){
            sum+=doubleCeil();
        }
        return sum;
    }


    static long execIntegerCeil(int count){
        long sum = 0;
        for(int i=0;i<count;i++){
            sum+=integerCeil();
        }
        return sum;
    }

    static void log(String msg, Object... params){
        String s = params.length>0?String.format(msg, params):msg;
        System.out.printf("%tH:%<tM:%<tS.%<tL %s%n", new Long(System.currentTimeMillis()), s);
    }   
}

This is also a working solution:

function array_insert(&$array,$element,$position=null) {
  if (count($array) == 0) {
    $array[] = $element;
  }
  elseif (is_numeric($position) && $position < 0) {
    if((count($array)+position) < 0) {
      $array = array_insert($array,$element,0);
    }
    else {
      $array[count($array)+$position] = $element;
    }
  }
  elseif (is_numeric($position) && isset($array[$position])) {
    $part1 = array_slice($array,0,$position,true);
    $part2 = array_slice($array,$position,null,true);
    $array = array_merge($part1,array($position=>$element),$part2);
    foreach($array as $key=>$item) {
      if (is_null($item)) {
        unset($array[$key]);
      }
    }
  }
  elseif (is_null($position)) {
    $array[] = $element;
  }  
  elseif (!isset($array[$position])) {
    $array[$position] = $element;
  }
  $array = array_merge($array);

Standard resource files are easier. However, if you have any language dependent data such as lookup tables then you will have to manage two resource sets.

I haven't done it, but in my next project I would implement a database resource provider. I found how to do it on MSDN:

http://msdn.microsoft.com/en-us/library/aa905797.aspx

I also found this implementation:

I have uninstalled Microsoft ASP.NET MVC nuget.org from manage NuGet Packagaes and again re-installed it. While re-installing it resolved all the conflicts related to razor version. Try it .

I call it my billion-dollar mistake…At that time, I was designing the first comprehensive type system for references in an object-oriented language. My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. But I couldn’t resist the temptation to put in a null reference, simply because it was so easy to implement. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years. – Tony Hoare, inventor of ALGOL W.

See here for an elaborate shit storm about null in general. I do not agree with the statement that undefined is another null, but it is still worth reading. And it explains, why you should avoid null at all and not just in the case you have asked. The essence is, that null is in any language a special case. You have to think about null as an exception. undefined is different in that way, that code dealing with undefined behavior is in most cases just a bug. C and most other languages have also undefined behavior but most of them have no identifier for that in the language.

Not much documentation on PowerShell loops.

Documentation on loops in PowerShell is plentiful, and you might want to check out the following help topics: about_For, about_ForEach, about_Do, about_While.

foreach($line in Get-Content .\file.txt) {
    if($line -match $regex){
        # Work here
    }
}

Another idiomatic PowerShell solution to your problem is to pipe the lines of the text file to the ForEach-Object cmdlet:

Get-Content .\file.txt | ForEach-Object {
    if($_ -match $regex){
        # Work here
    }
}

Instead of regex matching inside the loop, you could pipe the lines through Where-Object to filter just those you're interested in:

Get-Content .\file.txt | Where-Object {$_ -match $regex} | ForEach-Object {
    # Work here
}

Try XSSFilter.

if you are using jquery-validate.js in your application then use below expression.

if($("#spa").is(":blank"))
{

}

console.log works.

By default on iOS, it logs to the debug pane inside Xcode.

From the IOS simulator press (?+D) and press Remote JS Debugging. This will open a resource, http://localhost:8081/debugger-ui on localhost. From there use Chrome Developer tools javascript console to view console.log

This error could be an indication that variable with the same name has been used in your code earlier, but for other purposes. Possibly, a variable has been given a name that coincides with the existing function used later in the code.

The first approach is building separate Django and React apps. Django will be responsible for serving the API built using Django REST framework and React will consume these APIs using the Axios client or the browser's fetch API. You'll need to have two servers, both in development and production, one for Django(REST API) and the other for React (to serve static files).

The second approach is different the frontend and backend apps will be coupled. Basically you'll use Django to both serve the React frontend and to expose the REST API. So you'll need to integrate React and Webpack with Django, these are the steps that you can follow to do that

First generate your Django project then inside this project directory generate your React application using the React CLI

For Django project install django-webpack-loader with pip:

pip install django-webpack-loader

Next add the app to installed apps and configure it in settings.py by adding the following object

WEBPACK_LOADER = {
    'DEFAULT': {
            'BUNDLE_DIR_NAME': '',
            'STATS_FILE': os.path.join(BASE_DIR, 'webpack-stats.json'),
        }
}

Then add a Django template that will be used to mount the React application and will be served by Django

{ % load render_bundle from webpack_loader % }

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width" />
    <title>Django + React </title>
  </head>
  <body>
    <div id="root">
     This is where React will be mounted
    </div>
    { % render_bundle 'main' % }
  </body>
</html>

Then add an URL in urls.py to serve this template

from django.conf.urls import url
from django.contrib import admin
from django.views.generic import TemplateView

urlpatterns = [

    url(r'^', TemplateView.as_view(template_name="main.html")),

]

If you start both the Django and React servers at this point you'll get a Django error saying the webpack-stats.json doesn't exist. So next you need to make your React application able to generate the stats file.

Go ahead and navigate inside your React app then install webpack-bundle-tracker

npm install webpack-bundle-tracker --save

Then eject your Webpack configuration and go to config/webpack.config.dev.js then add

var BundleTracker  = require('webpack-bundle-tracker');
//...

module.exports = {

    plugins: [
          new BundleTracker({path: "../", filename: 'webpack-stats.json'}),
    ]
}

This add BundleTracker plugin to Webpack and instruct it to generate webpack-stats.json in the parent folder.

Make sure also to do the same in config/webpack.config.prod.js for production.

Now if you re-run your React server the webpack-stats.json will be generated and Django will be able to consume it to find information about the Webpack bundles generated by React dev server.

There are some other things to. You can find more information from this tutorial.

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

JVM uses the proxy to make HTTP calls

System.getProperties().put("http.proxyHost", "someProxyURL");
System.getProperties().put("http.proxyPort", "someProxyPort");

This may use user setting proxy

System.setProperty("java.net.useSystemProxies", "true");

With rails >= 3.0, you can simply use the placeholder option.

f.text_field :attr, placeholder: "placeholder text"

    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:template match="/">
        <newBooks>
                <xsl:for-each select="books/book">
                        <newBook>
                                <countNo><xsl:value-of select="position()"/></countNo>
                                <title>
                                        <xsl:value-of select="title"/>
                                </title>
                        </newBook>
                </xsl:for-each>
        </newBooks>
    </xsl:template>
</xsl:stylesheet>

None of the above filters fixed my issue so I had to copy the filter from official github doc. And then use it as explained in the above answers

angular.module('yourAppNameHere').filter('unique', function () {

return function (items, filterOn) {

if (filterOn === false) {
  return items;
}

if ((filterOn || angular.isUndefined(filterOn)) && angular.isArray(items)) {
  var hashCheck = {}, newItems = [];

  var extractValueToCompare = function (item) {
    if (angular.isObject(item) && angular.isString(filterOn)) {
      return item[filterOn];
    } else {
      return item;
    }
  };

  angular.forEach(items, function (item) {
    var valueToCheck, isDuplicate = false;

    for (var i = 0; i < newItems.length; i++) {
      if (angular.equals(extractValueToCompare(newItems[i]), extractValueToCompare(item))) {
        isDuplicate = true;
        break;
      }
    }
    if (!isDuplicate) {
      newItems.push(item);
    }

  });
  items = newItems;
}
return items;
  };

});

Depending on what you're trying to do you could also use curl_multi to achieve it.

This is one possible solution although not very clean:

1. Make the property you need to expose to BAL & DAL internal
2. Mark BAL.dll & DAL.dll Internal Visible in assemblyinfo.cs

public class Person
{
    public Person(int id)
    {
         this.Id=id;
    }

    public string Name { get;  set; }
    public int Id { get; internal set; }
    public int Age { get; set; }
}

AssemblyInfo.cs for Entities.dll

[assembly: InternalsVisibleTo("DAL"), InternalsVisibleTo("BAL")]

That way all your internals will be visible to DAL & BAL. This may not be desirable but I'm just suggesting one possible solution.

Without your actual data or source, it will be hard for us to diagnose what is going wrong. However, I can make a few suggestions:

• Unicode NUL (0x00) is illegal in all versions of XML and validating parsers must reject input that contains it.
• Despite the above; real-world non-validated XML can contain any kind of garbage ill-formed bytes imaginable.
• XML 1.1 allows zero-width and nonprinting control characters (except NUL), so you cannot look at an XML 1.1 file in a text editor and tell what characters it contains.

Given what you wrote, I suspect whatever converts the database data to XML is broken; it's propagating non-XML characters.

Create some database entries with non-XML characters (NULs, DELs, control characters, et al.) and run your XML converter on it. Output the XML to a file and look at it in a hex editor. If this contains non-XML characters, your converter is broken. Fix it or, if you cannot, create a preprocessor that rejects output with such characters.

If the converter output looks good, the problem is in your XML consumer; it's inserting non-XML characters somewhere. You will have to break your consumption process into separate steps, examine the output at each step, and narrow down what is introducing the bad characters.

Check file encoding (for UTF-16)

Update: I just ran into an example of this myself! What was happening is that the producer was encoding the XML as UTF16 and the consumer was expecting UTF8. Since UTF16 uses 0x00 as the high byte for all ASCII characters and UTF8 doesn't, the consumer was seeing every second byte as a NUL. In my case I could change encoding, but suggested all XML payloads start with a BOM.

You can do something like this

import React from 'react';

class Header extends React.Component {

constructor() {
    super();
}

checkClick(e, notyId) {
    alert(notyId);
}

render() {
    return (
        <PopupOver func ={this.checkClick } />
    )
}
};

class PopupOver extends React.Component {

constructor(props) {
    super(props);
    this.props.func(this, 1234);
}

render() {
    return (
        <div className="displayinline col-md-12 ">
            Hello
        </div>
    );
}
}

export default Header;

Using statics

var MyComponent = React.createClass({
 statics: {
 customMethod: function(foo) {
  return foo === 'bar';
  }
 },
   render: function() {
 }
});

MyComponent.customMethod('bar');  // true

private int user_movie_matrix[][];Th. should be `private int user_movie_matrix[][];.

private int user_movie_matrix[][]; should be private static int user_movie_matrix[][];

cfiltering(numberOfUsers, numberOfMovies); should be new cfiltering(numberOfUsers, numberOfMovies);

Whether or not the code works as intended after these changes is beyond the scope of this answer; there were several syntax/scoping errors.

The correct answer:

<form role="search" method="get" action="" target="_blank"></form>

Supported in all major browsers :)

def (value1, value2) = '1128-2'.split('-') should work.

Can anyone please try this in Groovy Console?

def (v, z) =  '1128-2'.split('-')

assert v == '1128'
assert z == '2'

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

You can have a static field to store this kind of state. Or put it to the resource Bundle and restore from there on onCreate(Bundle savedInstanceState). Just make sure you entirely understand Android app managed lifecycle (e.g. why login() gets called on keyboard orientation change).

Perfect for date of birth fields (and what I use) is similar to what Shog9 said, although I'm going to give a more specific DOB example:

$(".datePickerDOB").datepicker({ 
    yearRange: "-122:-18", //18 years or older up to 122yo (oldest person ever, can be sensibly set to something much smaller in most cases)
    maxDate: "-18Y", //Will only allow the selection of dates more than 18 years ago, useful if you need to restrict this
    minDate: "-122Y"
});

Hope future googlers find this useful :).

You can't call it asynchronously, since there is no asynchronous property support, only async methods. As such, there are two options, both taking advantage of the fact that asynchronous methods in the CTP are really just a method that returns Task<T> or Task:

// Make the property return a Task<T>
public Task<IEnumerable> MyList
{
    get
    {
         // Just call the method
         return MyAsyncMethod();
    }
}

Or:

// Make the property blocking
public IEnumerable MyList
{
    get
    {
         // Block via .Result
         return MyAsyncMethod().Result;
    }
}

Gallery is the best solution, i have tried it. I was working on one mail app, in which mails in the inbox where displayed as listview, i wanted an horizontal view, i just converted listview to gallery and everything worked fine as i needed without any errors. For the scroll effect i enabled gesture listener for the gallery. I hope this answer may help u.

Put this in the <head> section:

<link rel="icon" href="http://www.domain.com/favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="http://www.domain.com/favicon.ico" type="image/x-icon" />

Keep the picture file named "favicon.ico". You'll have to look online to get a .ico file generator.

If you have a variable

int k;

You can get its type using

cout << typeid(k).name() << endl;

See the following thread on SO: Similar question

You're using smart quotes. That is, instead of standard quotation marks ("), you are using curly quotes (”). This happens automatically with Microsoft Word and other word processors to make things look prettier, but it also mangles HTML. Make sure to code in a plain text editor, like Notepad or Notepad2.

Can you try this,

echo date("Y-m-d H:i:s", 1388516401);

As noted by theGame,

This means that you pass in a string value for the time, and optionally a value for the current time, which is a UNIX timestamp. The value that is returned is an integer which is a UNIX timestamp.

echo strtotime("2014-01-01 00:00:01");

This will return into the value 1388516401, which is the UNIX timestamp for the date 2014-01-01. This can be confirmed using the date() function as like below:

echo date('Y-m-d', 1198148400); // echos 2014-01-01

The specific value in your database isn't what you should be focusing on. This is likely the result of an attacker fuzzing your system to see if it is vulnerable to a set of standard attacks, instead of a targeted attack exploiting a known vulnerability.

You should instead focus on ensuring that your application is secure against these types of attacks; OWASP is a good resource for this.

If you're using parameterized queries to access the database, then you're secure against Sql injection, unless you're using dynamic Sql in the backend as well.

If you're not doing this, you're vulnerable and you should resolve this immediately.

Also, you should consider performing some sort of validation of e-mail addresses.

How about the yahoo's media player Just embed yahoo's library

<script type="text/javascript" src="http://mediaplayer.yahoo.com/js"></script> 

And use it like

<a id="beep" href="song.mp3">Play Song</a>

To autostart

$(function() { $("#beep").click(); });

You can't use String.isEmpty() if it is null. Best is to have your own method to check null or empty.

public static boolean isBlankOrNull(String str) {
    return (str == null || "".equals(str.trim()));
}

are you using jquery and prototype on the same page by any chance?

If so, use jquery noConflict mode, otherwise you are overwriting prototypes $ function.

noConflict mode is activated by doing the following:

<script src="jquery.js"></script>
<script>jQuery.noConflict();</script>

Note: by doing this, the dollar sign variable no longer represents the jQuery object. To keep from rewriting all your jQuery code, you can use this little trick to create a dollar sign scope for jQuery:

jQuery(function ($) {
    // The dollar sign will equal jQuery in this scope
});

// Out here, the dollar sign still equals Prototype

I was experiencing this problem even though my Theme was an AppCompat Theme and my Activity was an AppCompatActivity (or Activity, as suggested on other's answers). So I cleaned, rebuild and rerun the project.

It may seem dumb, but now it works great!

Just hope it helps!

emacs hello.c -nw

This is to open a hello.c file using Emacs inside the terminal.

This is based off of "default locale"'s answer but it will remove invalid column names prior to setting ordinal. This is because if you accidentally send an invalid column name then it would fail and if you put a check to prevent it from failing then the index would be wrong since it would skip indices wherever an invalid column name was passed in.

public static class DataTableExtensions
{
    /// <summary>
    /// SetOrdinal of DataTable columns based on the index of the columnNames array. Removes invalid column names first.
    /// </summary>
    /// <param name="table"></param>
    /// <param name="columnNames"></param>
    /// <remarks> http://stackoverflow.com/questions/3757997/how-to-change-datatable-colums-order</remarks>
    public static void SetColumnsOrder(this DataTable dtbl, params String[] columnNames)
    {
        List<string> listColNames = columnNames.ToList();

        //Remove invalid column names.
        foreach (string colName in columnNames)
        {
            if (!dtbl.Columns.Contains(colName))
            {
                listColNames.Remove(colName);
            }
        }

        foreach (string colName in listColNames)
        {
            dtbl.Columns[colName].SetOrdinal(listColNames.IndexOf(colName));
        }
}

You could run: mvn exec:exec -Dexec.args="arg1".

This will pass the argument arg1 to your program.

You should specify the main class fully qualified, for example, a Main.java that is in a package test would need

mvn exec:java  -Dexec.mainClass=test.Main

By using the -f parameter, as decribed here, you can also run it from other directories.

mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm

For multiple arguments, simply separate them with a space as you would at the command line.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"

For arguments separated with a space, you can group using 'argument separated with space' inside the quotation marks.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"

You can try

Subject[] subjects = new Subject[2];
subjects[0] = new Subject{....};
subjects[1] = new Subject{....};

alternatively you can use List

List<Subject> subjects = new List<Subject>();
subjects.add(new Subject{....});
subjects.add(new Subject{....});

Disclaimer: @theTinMan and other Ruby developers often point out not to use sudo when installing gems and point to things like RVM. That's absolutely true when doing Ruby development. Go ahead and use that.

However, many of us just want some binary that happens to be distributed as a gem (e.g. fakes3, cocoapods, xcpretty …). I definitely don't want to bother with managing a separate ruby. Here are your quicker options:

Option 1: Keep using sudo

Using sudo is probably fine if you want these tools to be installed globally.

The problem is that these binaries are installed into /usr/bin, which is off-limits since El Capitan. However, you can install them into /usr/local/bin instead. That's where Homebrew install its stuff, so it probably exists already.

sudo gem install fakes3 -n/usr/local/bin

Gems will be installed into /usr/local/bin and every user on your system can use them if it's in their PATH.

Option 2: Install in your home directory (without sudo)

The following will install gems in ~/.gem and put binaries in ~/bin (which you should then add to your PATH).

gem install fakes3 --user-install -n~/bin

Make it the default

Either way, you can add these parameters to your ~/.gemrc so you don't have to remember them:

gem: -n/usr/local/bin

i.e. echo "gem: -n/usr/local/bin" >> ~/.gemrc

or

gem: --user-install -n~/bin

i.e. echo "gem: --user-install -n~/bin" >> ~/.gemrc

(Tip: You can also throw in --no-document to skip generating Ruby developer documentation.)

I found that jquery 1.11.1 does not do this reliably.

I used $('#estimate').attr('required', true) and $('#estimate').removeAttr('required').

Removing required was not reliable. It would sometimes leave the required attribute without value. Since required is a boolean attibute, its mere presence, without value, is seen by the browser as true.

This bug was intermittent, and I got tired of messing with it. Switched to document.getElementById("estimate").required = true and document.getElementById("estimate").required = false.

this worked for me :)

select * from Common

where

common_id not in (select ISNULL(common_id,'dummy-data') from Table1)

and common_id not in (select ISNULL(common_id,'dummy-data') from Table2)

1) Open your terminal and type

npm install -g http-server

2) Go to the root folder that you want to serve you files and type:

http-server ./

3) Read the output of the terminal, something kinda http://localhost:8080 will appear.

Everything on there will be allowed to be got. Example:

background: url('http://localhost:8080/waw.png');

Add this to <system.webServer> in your web.config:

<handlers>
    <remove name="ExtensionlessUrlHandler-Integrated-4.0"/>
    <remove name="OPTIONSVerbHandler"/>
    <remove name="TRACEVerbHandler"/>
    <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler"
        preCondition="integratedMode,runtimeVersionv4.0"/>
</handlers>

Adding <modules runAllManagedModulesForAllRequests="true" /> also works but is not recommended due performance issues.

If we follow the activity template created by Android Studios, it's the AppBarLayout that needs to have an android theme of AppBarOverlay, which you should define in the your styles.xml. That should give you your white color toobar/actionbar color text.

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">  ...

In styles.xml, make sure the following exists:

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

This is an old question but a solution for those using Excel 2016 or newer is you can remove the need for nested if structures by using the new IFS( condition1, return1 [,condition2, return2] ...) conditional.

I have formatted it to make it visually clearer on how to use it for the case of this question:

=IFS(
ISERROR(SEARCH("String1",A1))=FALSE,"Something1",
ISERROR(SEARCH("String2",A1))=FALSE,"Something2",
ISERROR(SEARCH("String3",A1))=FALSE,"Something3"
)

Since SEARCH returns an error if a string is not found I wrapped it with an ISERROR(...)=FALSE to check for truth and then return the value wanted. It would be great if SEARCH returned 0 instead of an error for readability, but thats just how it works unfortunately.

Another note of importance is that IFS will return the match that it finds first and thus ordering is important. For example if my strings were Surf, Surfing, Surfs as String1,String2,String3 above and my cells string was Surfing it would match on the first term instead of the second because of the substring being Surf. Thus common denominators need to be last in the list. My IFS would need to be ordered Surfing, Surfs, Surf to work correctly (swapping Surfing and Surfs would also work in this simple example), but Surf would need to be last.

When the argument -Xss doesn't do the job try deleting the temporary files from:

c:\Users\{user}\AppData\Local\Temp\.

This did the trick for me.

function liReplace(replacement) {
    $(".dropit-submenu li").each(function() {
        var t = $(this);
        t.html(t.html().replace(replacement, "*" + replacement + "*"));
        t.children(":first").html(t.children(":first").html().replace(replacement, "*" +` `replacement + "*"));
        t.children(":first").html(t.children(":first").html().replace(replacement + " ", ""));
        alert(t.children(":first").text());
    });
}

• First code find a title replace t.html(t.html()
• Second code a text replace t.children(":first")

Sample <a title="alpc" href="#">alpc</a>

Ok. I found the solution here tessnet2 fails to load the Ans given by Adam

Apparently i was using wrong version of tessdata. I was following the the source page instruction intuitively and that caused the problem.

it says

Quick Tessnet2 usage

1. Download binary here, add a reference of the assembly Tessnet2.dll to your .NET project.

2. Download language data definition file here and put it in tessdata directory. Tessdata directory and your exe must be in the same directory.

After you download the binary, when you follow the link to download the language file, there are many language files. but none of them are right version. you need to select all version and go to next page for correct version (tesseract-2.00.eng)! They should either update download binary link to version 3 or put the the version 2 language file on the first page. Or at least bold mention the fact that this version issue is a big deal!

Anyway I found it. Thanks everyone.

Maven 3 is more restrictive with the POM-Structure. You have to set versions of Plugins for instance.

With maven 3.1 these warnings may break you build. There are more changes between maven2 and maven3: https://cwiki.apache.org/confluence/display/MAVEN/Maven+3.x+Compatibility+Notes

Both keywords are equivalent, but there are a few caveats. One is that declaring a function pointer with using T = int (*)(int, int); is clearer than with typedef int (*T)(int, int);. Second is that template alias form is not possible with typedef. Third is that exposing C API would require typedef in public headers.

Performance-Wise this probably might not be the best solution but it works.

var str = "filename:with&bad$separators.txt";
char[] charArray = new char[] { '#', '%', '&', '{', '}', '\\', '<', '>', '*', '?', '/', ' ', '$', '!', '\'', '"', ':', '@' };
foreach (var singleChar in charArray)
{
   str = str.Replace(singleChar, '_');
}

Not sure, if that's what you want, but you could make the inner div an inline-element. This way the border should be wrapped only around the text. Even better than that is to use an inline-element for your title.

Solution 1

<div id="page" style="width: 600px;">
    <div id="title" style="display: inline; border...">Title</div>
</div>

Solution 2

<div id="page" style="width: 600px;">
    <span id="title" style="border...">Title</span>
</div>

Edit: Strange, SO doesn't interpret my code-examples correctly as block, so I had to use inline-code-method.

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

if(displayit){
  login_div.Style["display"]="inline"; //the default display mode
}else{
  login_div.Style["display"]="none";
}

Adding this code into Page_Load should work. (if doing it at Page_Init you'll have to contend with viewstate changing what you put in it)

int integer = 60;
byte[] bytes = new byte[4];
for (int i = 0; i < 4; i++) {
    bytes[i] = (byte)(integer >>> (i * 8));
}

we just can show same label div on hovering like this

<style>
#b {
    display: none;
}

#content:hover~#b{
    display: block;
}

</style>

You can also include android:windowSoftInputMode="stateAlwaysHidden" in your manifest action section.

This is equivalent to:

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

The situation you describe is pretty fishy. Whenever you close your program's startup form, the entire application should quit automatically, including closing all other open forms. Make sure that you're closing the correct form, and you should not experience any problems.

The other possibility is that you've changed your project (using its Properties page) not to close until all open windows have been closed. In this mode, your application will not exit until the last remaining open form has been closed. If you've chosen this setting, you have to make sure that you call the Close method of all forms that you've shown during the course of application, not just the startup/main form.

The first setting is the default for a reason, and if you've changed it, you probably want to go fix it back.
It is by far the most intuitive model for normal applications, and it prevents exactly the situation you describe. For it to work properly, make sure that you have specified your main form as the "Startup form" (rather than a splash screen or log-in form).

The settings I'm talking about are highlighted here:

But primarily, note that you should never have to call Application.Exit in a properly-designed application. If you find yourself having to do this in order for your program to close completely, then you are doing something wrong. Doing it is not a bad practice in itself, as long as you have a good reason. The other two answers fail to explain that, and thus I feel are incomplete at best.

A lot of C projects end up implementing a vector-like API. Dynamic arrays are such a common need, that it's nice to abstract away the memory management as much as possible. A typical C implementation might look something like:

typedef struct dynamic_array_struct
{
  int* data;
  size_t capacity; /* total capacity */
  size_t size; /* number of elements in vector */
} vector;

Then they would have various API function calls which operate on the vector:

int vector_init(vector* v, size_t init_capacity)
{
  v->data = malloc(init_capacity * sizeof(int));
  if (!v->data) return -1;

  v->size = 0;
  v->capacity = init_capacity;

  return 0; /* success */
}

Then of course, you need functions for push_back, insert, resize, etc, which would call realloc if size exceeds capacity.

vector_resize(vector* v, size_t new_size);

vector_push_back(vector* v, int element);

Usually, when a reallocation is needed, capacity is doubled to avoid reallocating all the time. This is usually the same strategy employed internally by std::vector, except typically std::vector won't call realloc because of C++ object construction/destruction. Rather, std::vector might allocate a new buffer, and then copy construct/move construct the objects (using placement new) into the new buffer.

An actual vector implementation in C might use void* pointers as elements rather than int, so the code is more generic. Anyway, this sort of thing is implemented in a lot of C projects. See http://codingrecipes.com/implementation-of-a-vector-data-structure-in-c for an example vector implementation in C.

When speaking of "what is faster" - there are at least two very different aspects: throughput and latency.

If speaking about throughput - TCP's flow control (as mentioned in other answers), is extremely important and doing anything comparable over UDP, while certainly possible, would be a Big Headache(tm). As a result - using UDP when you need throughput, rarely qualifies as a good idea (unless you want to get an unfair advantage over TCP).

However, if speaking about latencies - the whole thing is completely different. While in the absence of packet loss TCP and UDP behave extremely similar (any differences, if any, being marginal) - after the packet is lost, the whole pattern changes drastically.

After any packet loss, TCP will wait for retransmit for at least 200ms (1sec per paragraph 2.4 of RFC6298, but practical modern implementations tend to reduce it to 200ms). Moreover, with TCP, even those packets which did reach destination host - will not be delivered to your app until the missing packet is received (i.e., the whole communication is delayed by ~200ms) - BTW, this effect, known as Head-of-Line Blocking, is inherent to all reliable ordered streams, whether TCP or reliable+ordered UDP. To make things even worse - if the retransmitted packet is also lost, then we'll be speaking about delay of ~600ms (due to so-called exponential backoff, 1st retransmit is 200ms, and second one is 200*2=400ms). If our channel has 1% packet loss (which is not bad by today's standards), and we have a game with 20 updates per second - such 600ms delays will occur on average every 8 minutes. And as 600ms is more than enough to get you killed in a fast-paced game - well, it is pretty bad for gameplay. These effects are exactly why gamedevs often prefer UDP over TCP.

However, when using UDP to reduce latencies - it is important to realize that merely "using UDP" is not sufficient to get substantial latency improvement, it is all about HOW you're using UDP. In particular, while RUDP libraries usually avoid that "exponential backoff" and use shorter retransmit times - if they are used as a "reliable ordered" stream, they still have to suffer from Head-of-Line Blocking (so in case of a double packet loss, instead of that 600ms we'll get about 1.5*2*RTT - or for a pretty good 80ms RTT, it is a ~250ms delay, which is an improvement, but it is still possible to do better). On the other hand, if using techniques discussed in http://gafferongames.com/networked-physics/snapshot-compression/ and/or http://ithare.com/udp-from-mog-perspective/#low-latency-compression , it IS possible to eliminate Head-of-Line blocking entirely (so for a double-packet loss for a game with 20 updates/second, the delay will be 100ms regardless of RTT).

And as a side note - if you happen to have access only to TCP but no UDP (such as in browser, or if your client is behind one of 6-9% of ugly firewalls blocking UDP) - there seems to be a way to implement UDP-over-TCP without incurring too much latencies, see here: http://ithare.com/almost-zero-additional-latency-udp-over-tcp/ (make sure to read comments too(!)).

I've found that the best (and easiest) way to delete leading, trailing (and excessive) spaces in Excel is to use a third-party plugin. I've been using ASAP Utilities for Excel and it accomplishes the task as well as adds many other much-needed features. This approach doesn't require writing formulas and can remove spaces on any selection spanning multiple columns and/or rows. I also use this to sanitize and remove the uninvited non-breaking space that often finds its way into Excel data when copying-and-pasting from other Microsoft products.

More information regarding ASAP Utilities and trimming can be found here:

I had an "Invalid Name"

I switched from "name": "Some Name",... to "name": "Some-Name",...

Guess name needs to be a sluggy string.

In your Ruby on Rails controller you can use:

private

before_filter :safari_cookie_fix

def safari_cookie_fix
  user_agent = UserAgent.parse(request.user_agent) # Uses useragent gem!
  if user_agent.browser == 'Safari' # we apply the fix..
    return if session[:safari_cookie_fixed] # it is already fixed.. continue
    if params[:safari_cookie_fix].present? # we should be top window and able to set cookies.. so fix the issue :)
      session[:safari_cookie_fixed] = true
      redirect_to params[:return_to]
    else
      # Redirect the top frame to your server..
      render :text => "<script>alert('start redirect');top.window.location='?safari_cookie_fix=true&return_to=#{set_your_return_url}';</script>"
    end
  end
end

Because you rebased feature on top of the new master, your local feature is not a fast-forward of origin/feature anymore. So, I think, it's perfectly fine in this case to override the fast-forward check by doing git push origin +feature. You can also specify this in your config

git config remote.origin.push +refs/heads/feature:refs/heads/feature

If other people work on top of origin/feature, they will be disturbed by this forced update. You can avoid that by merging in the new master into feature instead of rebasing. The result will indeed be a fast-forward.

My controller

public function delete_category()   //Created a controller class //
    {      
         $this->load->model('Managecat'); //Load model Managecat here 
         $id=$this->input->get('id');     //  get the requested in a variable
         $sql_del=$this->Managecat->deleteRecord($id); //send the parameter $id in Managecat  there I have created a function name deleteRecord

         if($sql_del){

               $data['success'] = "Category Have been deleted Successfully!!";  //success message goes here 

         }

    }

My Model

public function deleteRecord($id) {

    $this->db->where('cat_id', $id);
    $del=$this->db->delete('category');   
    return $del;

}

Try this:

 try
                    {
                        TransformerFactory transFactory = TransformerFactory.newInstance();
                        Transformer transformer = null;
                        transformer = transFactory.newTransformer();
                        StringWriter buffer = new StringWriter();
                        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
                        transformer.transform(new DOMSource(element),
                                  new StreamResult(buffer)); 
                        String str = buffer.toString();
                        System.out.println("XML INSIDE IS #########################################"+str);
                        return element;
                    }
                    catch (TransformerConfigurationException e)
                    {
                        e.printStackTrace();
                    }
                    catch (TransformerException e)
                    {
                        e.printStackTrace();
                    }

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

A keystore contains private keys, and the certificates with their corresponding public keys.

A truststore contains certificates from other parties that you expect to communicate with, or from Certificate Authorities that you trust to identify other parties.

Use wordwrap() to truncate the string without breaking words if the string is longer than 50 characters, and just add ... at the end:

$str = $input;
if( strlen( $input) > 50) {
    $str = explode( "\n", wordwrap( $input, 50));
    $str = $str[0] . '...';
}

echo $str;

Otherwise, using solutions that do substr( $input, 0, 50); will break words.
