You can only delete with your time field, which is a number.

Delete from <measurement> where time=123456

will work. Remember not to give single quotes or double quotes. Its a number.

I made this plugin. There is some css interference taking place.

It's your border on the slider itself. Either use

box-sizing: border-box 

to absorb the border width, or put the border on the content inside the slide.

According to your requirement

just show me a basic example of using setTimeout to loop something

we have following example which can help you

var itr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];_x000D_
var  interval = 1000; //one second_x000D_
itr.forEach((itr, index) => {_x000D_
_x000D_
  setTimeout(() => {_x000D_
    console.log(itr)_x000D_
  }, index * interval)_x000D_
})

You didn't include the base jQuery Validation library:

<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.js"></script>

Put that before the additional methods library. (BTW this is a hosted version, download your own if you want)

Saw this thread but I wanted to search for IDs that did not match my search. Code to do that:

found = $filter('filter')($scope.fish, {id: '!fish_id'}, false);

        function yourfunctionName() {
            var yourFileName = $("#yourinputfieldis").val();

            var yourFileExtension = yourFileName .replace(/^.*\./, '');
            switch (yourFileExtension ) {
                case 'pdf':
                case 'jpg':
                case 'doc':
                    $("#formId").submit();// your condition what you want to do
                    break;
                default:
                    alert('your File extension is wrong.');
                    this.value = '';
            }    
        }

The validation was working for me on form submission, but it wasn't doing the reactive event driven validation on input to the chosen select lists.

To fix this I added the following to manually trigger the jquery validation event that gets added by the library:

$(".chosen-select").each(function() {
  $(this).chosen().on("change", function() {
    $(this).parents(".form-group").find("select.form-control").trigger("focusout.validate");
  });
});

jquery.validate will now add the .valid class to the underlying select list.

Caveat: This does require a consistent html pattern for your form inputs. In my case, each input filed is wrapped in a div.form-group, and each input has .form-control.

I was using Java 1.8, and this error suddenly occurred when I pressed "Build and clean" in NetBeans. I switched for a brief moment to 1.7 again, clicked OK, re-opened properties and switched back to 1.8, and everything worked perfectly.

I hope I can help someone out with this, as these errors can be quite time-consuming.

@mikemaccana answer is useful.

And I also used https://github.com/ryanseddon/H5F. Found on http://microjs.com. It's some kind of polyfill and you can use it as follows (jQuery is used in example):

if ( $('form')[0].checkValidity() ) {
    // the form is valid
}

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

            google.maps.event.addListener(marker, 'click', function () {
                infoWindow.open(map, marker);
            });
        }

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

Wait -- did you actually mean that "the same number of rows ... are being processed" or that "the same number of rows are being returned"? In general, the outer join would process many more rows, including those for which there is no match, even if it returns the same number of records.

This question is old, but I found another way around it is to use $('#formId')[0].submit(), which gets the dom element instead of the jQuery object, thus bypassing any validation hooks. This button submits the parent form that contains the input.

<input type='button' value='SubmitWithoutValidation' onclick='$(this).closest('form')[0].submit()'/>

Also, make sure you don't have any input's named "submit", or it overrides the function named submit.

If you are using MacBook Pro (OS X) follow the following steps:

python > Preference > Syntax coloring

Update July 1st 2019

docker-compose logs <name-of-service>

From the documentation:

Usage: logs [options] [SERVICE...]

Options:

--no-color Produce monochrome output.

-f, --follow Follow log output.

-t, --timestamps Show timestamps.

--tail="all" Number of lines to show from the end of the logs for each container.

See docker logs

You can start Docker compose in detached mode and attach yourself to the logs of all container later. If you're done watching logs you can detach yourself from the logs output without shutting down your services.

1. Use docker-compose up -d to start all services in detached mode (-d) (you won't see any logs in detached mode)
2. Use docker-compose logs -f -t to attach yourself to the logs of all running services, whereas -f means you follow the log output and the -t option gives you timestamps (See Docker reference)
3. Use Ctrl + z or Ctrl + c to detach yourself from the log output without shutting down your running containers

If you're interested in logs of a single container you can use the docker keyword instead:

1. Use docker logs -t -f <name-of-service>

Save the output

To save the output to a file you add the following to your logs command:

1. docker-compose logs -f -t >> myDockerCompose.log

I was using some buttons with some events, converted image file coming from server. Loading normal data wasn't working for me, converting into Base64 working just fine.

String unencodedHtml ="<html><body>'%28' is the code for '('</body></html>";
tring encodedHtml = Base64.encodeToString(unencodedHtml.getBytes(), Base64.NO_PADDING);
webView.loadData(encodedHtml, "text/html", "base64");

Find details on WebView

You made the error, for the second call, to set the size of source to the size of the target.
Anyway i bet that you want the same aspect ratio for the scaled image, so you need to compute it :

var hRatio = canvas.width / img.width    ;
var vRatio = canvas.height / img.height  ;
var ratio  = Math.min ( hRatio, vRatio );
ctx.drawImage(img, 0,0, img.width, img.height, 0,0,img.width*ratio, img.height*ratio);

i also suppose you want to center the image, so the code would be :

function drawImageScaled(img, ctx) {
   var canvas = ctx.canvas ;
   var hRatio = canvas.width  / img.width    ;
   var vRatio =  canvas.height / img.height  ;
   var ratio  = Math.min ( hRatio, vRatio );
   var centerShift_x = ( canvas.width - img.width*ratio ) / 2;
   var centerShift_y = ( canvas.height - img.height*ratio ) / 2;  
   ctx.clearRect(0,0,canvas.width, canvas.height);
   ctx.drawImage(img, 0,0, img.width, img.height,
                      centerShift_x,centerShift_y,img.width*ratio, img.height*ratio);  
}

you can see it in a jsbin here : http://jsbin.com/funewofu/1/edit?js,output

you can implement following regex regex = '^[6-9][0-9]{9}$'

The -L merely gives the path where to find the .a or .so file. What you're looking for is to add -lmine to the LIBS variable.

Make that -static -lmine to force it to pick the static library (in case both static and dynamic library exist).

Addition: Suppose the path to the file has been conveyed to the linker (or compiler driver) via -L you can also specifically tell it to link libfoo.a by giving -l:libfoo.a. Note that in this case the name includes the conventional lib-prefix. You can also give a full path this way. Sometimes this is the better method to "guide" the linker to the right location.

I presume that you're talking about bash strings. There are different types of strings which have a different set of requirements for escaping. eg. Single quotes strings are different from double quoted strings.

The best reference is the Quoting section of the bash manual.

It explains which characters needs escaping. Note that some characters may need escaping depending on which options are enabled such as history expansion.

You can convert it into string by using JSON and store it as string.

For example,

In [3]: json.dumps([[1, 3, 4], [4, 2, 6], [8, 12, 3], [3, 3, 9]])

Out[3]: '[[1, 3, 4], [4, 2, 6], [8, 12, 3], [3, 3, 9]]'

You can add a method into your class to convert it automatically for you.

import json


class Foobar(models.Model):
    foo = models.CharField(max_length=200)

    def set_foo(self, x):
        self.foo = json.dumps(x)

    def get_foo(self):
        return json.loads(self.foo)

If you're using Django 1.9 and postgresql, there is a new class called JSONField, you should use it instead. Here is a link to it

There is a good talk about PostgreSQL JSONs and Arrays on youtube. Watch it, it has very good information.

The onunload event is not called in all browsers. Worse, you cannot check the return value of onbeforeunload event. That prevents us from actually preforming a logout function.

However, you can hack around this.

Call logout first thing in the onbeforeunload event. then prompt the user. If the user cancels their logout, automatically login them back in, by using the onfocus event. Kinda backwards, but I think it should work.

'use strict';

var reconnect = false;

window.onfocus = function () {
  if (reconnect) {
    reconnect = false;
    alert("Perform an auto-login here!");
  }
};

window.onbeforeunload = function () {
  //logout();
  var msg = "Are you sure you want to leave?";
  reconnect = true;
  return msg;
};

Why $apply should be called?

TL;DR: $apply should be called whenever you want to apply changes made outside of Angular world.

Just to update @Dustin's answer, here is an explanation of what $apply exactly does and why it works.

$apply() is used to execute an expression in AngularJS from outside of the AngularJS framework. (For example from browser DOM events, setTimeout, XHR or third party libraries). Because we are calling into the AngularJS framework we need to perform proper scope life cycle of exception handling, executing watches.

Angular allows any value to be used as a binding target. Then at the end of any JavaScript code turn, it checks to see if the value has changed. That step that checks to see if any binding values have changed actually has a method, $scope.$digest()¹. We almost never call it directly, as we use $scope.$apply() instead (which will call $scope.$digest).

Angular only monitors variables used in expressions and anything inside of a $watch living inside the scope. So if you are changing the model outside of the Angular context, you will need to call $scope.$apply() for those changes to be propagated, otherwise Angular will not know that they have been changed thus the binding will not be updated².

I went searching around for a similar question - the way I've managed to initialize a Git repository for an existing project file is this (disclaimer: this is done in Visual Studio 2013 Express, without a Team Foundation Server setup):

1. Open the project in Visual Studio.
2. Go to menu File ? Add to Source Control.

That did it for me - assuming Git is set up for you, you can go to menu View ? Team Explorer, then double click the repository for your project file, and make your initial commit (making sure to add whatever files you'd like).

If performance is a priority, use data.table and na.omit() with optional param cols=.

na.omit.data.table is the fastest on my benchmark (see below), whether for all columns or for select columns (OP question part 2).

If you don't want to use data.table, use complete.cases().

On a vanilla data.frame, complete.cases is faster than na.omit() or dplyr::drop_na(). Notice that na.omit.data.frame does not support cols=.

Benchmark result

Here is a comparison of base (blue), dplyr (pink), and data.table (yellow) methods for dropping either all or select missing observations, on notional dataset of 1 million observations of 20 numeric variables with independent 5% likelihood of being missing, and a subset of 4 variables for part 2.

Your results may vary based on length, width, and sparsity of your particular dataset.

Note log scale on y axis.

1. Go to C:\Program Files\MongoDB\Server\3.4\bin using cmd and write mongod.
2. Open another cmd by right click and run as admin point to your monogodb installed directory as mentioned above and then just like write this mongo.exe
3. After that, write db.test.save({Field:'Hello mongodb'}) this command will insert a field having name Field and value is Hello mongodb.
4. After, check the record db.test.find() and press enter you will find the record that you have recently entered.

Yeah, you'd need to have a javascript function triggered by an onclick that does an AJAX load of a page and then returns false, that way they won't be redirected in the browser. You could use the following in jQuery, if that's acceptable for your project:

<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript">
function doSomething() {
    $.get("somepage.php");
    return false;
}
</script>

<a href="#" onclick="doSomething();">Click Me!</a>

You could also do a post-back if you need to use form values (use the $.post() method).

string tail = test.Substring(test.LastIndexOf('-') + 1);

If IIS app pool is running under classic mode, make sure you have the following in your web.config

<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />

    <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" modules="IsapiModule" scriptProcessor="c:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" />

I installed node for windows. There is a node.js command prompt when I search for node.js in windows 7 start menu If you run this special command prompt, you can node anything in any location without setting up the path or copy node.exe everywhere.

The tutorial @Henrik mentioned is an excellent resource for learning how to create plots with the ggplot2 package.

An example with your data:

# transforming the data from wide to long
library(reshape2)
dfm <- melt(df, id = "TY")

# creating a scatterplot
ggplot(data = dfm, aes(x = TY, y = value, color = variable)) + 
  geom_point(size=5) +
  labs(title = "Temperatures\n", x = "TY [°C]", y = "Txxx", color = "Legend Title\n") +
  scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
  theme_bw() +
  theme(axis.text.x = element_text(size = 14), axis.title.x = element_text(size = 16),
        axis.text.y = element_text(size = 14), axis.title.y = element_text(size = 16),
        plot.title = element_text(size = 20, face = "bold", color = "darkgreen"))

this results in:

As mentioned by @user2739472 in the comments: If you only want to change the legend text labels and not the colours from ggplot's default palette, you can use scale_color_hue(labels = c("T999", "T888")) instead of scale_color_manual().

Even though this is an old question, I've just come across the problem and solved it differently from the given answers. Maybe it could be helpful to others.

I noticed that even though my XML files looked like:

<tag>
 <subTag>content with newline.\r\nto display</subTag>
</tag>

When it was read into my C# code the string had double backslashes.

\\r\\n

To fix this I wrote a ValueConverter to strip the extra backslash.

public class XmlStringConverter : IValueConverter
{
    public object Convert(
        object value,
        Type targetType,
        object parameter,
        CultureInfo culture)
    {
        string valueAsString = value as string;
        if (string.IsNullOrEmpty(valueAsString))
        {
            return value;
        }

        valueAsString = valueAsString.Replace("\\r\\n", "\r\n");
        return valueAsString;
    }

    public object ConvertBack(
        object value,
        Type targetType,
        object parameter,
        CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

First initialize Property values

MutablePropertyValues mutablePropertyValues = new MutablePropertyValues();
mutablePropertyValues.add("hostName", details.getHostName());
mutablePropertyValues.add("port", details.getPort());

DefaultListableBeanFactory context = new DefaultListableBeanFactory();
GenericBeanDefinition connectionFactory = new GenericBeanDefinition();
connectionFactory.setBeanClass(Class);
connectionFactory.setPropertyValues(mutablePropertyValues);

context.registerBeanDefinition("beanName", connectionFactory);

Add to the list of beans

ConfigurableListableBeanFactory beanFactory = ((ConfigurableApplicationContext) applicationContext).getBeanFactory();
beanFactory.registerSingleton("beanName", context.getBean("beanName"));

QFile file("test.txt");
/*
 *If file does not exist, it will be created
 */
if (!file.open(QIODevice::ReadOnly | QIODevice::Text | QIODevice::ReadWrite))
{
    qDebug() << "FAILED TO CREATE FILE / FILE DOES NOT EXIST";
}

/*for Reading line by line from text file*/
while (!file.atEnd()) {
    QByteArray line = file.readLine();
    qDebug() << "read output - " << line;
}

/*for writing line by line to text file */
if (file.open(QIODevice::ReadWrite))
{
    QTextStream stream(&file);
    stream << "1_XYZ"<<endl;
    stream << "2_XYZ"<<endl;
}

It bothered me too much while updating node version from 8.1.0 to 10.14.0

Here is what worked for me:

1. Open terminal (Ctrl+Alt+T).

2. Type which node, which will give a path something like /usr/local/bin/node

3. Run the command sudo rm /usr/local/bin/node to remove the binary (adjust the path according to what you found in step 2). Now node -v shows you have no node version

4. Download a script and run it to set up the environment:

   curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
   

5. Install using sudo apt-get install nodejs

   Note: If you are getting error like

   node /usr/bin/env: node: No such file or directory
   

   just run

   ln -s /usr/bin/nodejs /usr/bin/node
   

   Source

6. Now node -v will give v10.14.0

Worked for me.

Your code is drawing the center of the baseline of the text, at the center of the view. In order to center the text at some point, x, y, you need to calculate the center of the text, and put that at the point.

This method will draw text centered at the point x, y. If you pass it the center of your view, it will draw the text centered.

private void drawTextCentered(String text, int x, int y, Paint paint, Canvas canvas) {
    int xPos = x - (int)(paint.measureText(text)/2);
    int yPos = (int) (y - ((textPaint.descent() + textPaint.ascent()) / 2)) ;

    canvas.drawText(text, xPos, yPos, textPaint);
}

Try updating your Ruby on Rails version to v3.0.5:

gem install rails --version 3.0.5

or v2.3.11:

gem install rails --version 2.3.11

If this isn't a new project you'll have to upgrade your application accordingly. If it was a new project, just delete the directory you created it in and create a new project again.

Install phantomjs

$ npm install phantomjs

Create a file github.js with following code

var page = require('webpage').create();
//viewportSize being the actual size of the headless browser
page.viewportSize = { width: 1024, height: 768 };
page.open('http://github.com/', function() {
    page.render('github.png');
    phantom.exit();
});

Pass the file as argument to phantomjs

$ phantomjs github.js

aca definis los anchos

 float[] anchoDeColumnas= new float[] {10f, 20f, 30f, 10f};

aca se los insertas a la tabla que tiene las columnas

table.setWidths(anchoDeColumnas);

CASE by definition only returns a single value. Ever.

It also (almost always) short circuits, which means if your first condition is met no other checks are run.

# -i (inplace)

sed -i 's/[\d128-\d255]//g' FILENAME

We tried pretty much what the other answers are describing with moderate level of success. What really worked for us (Apache Kafka 0.8.1) is the class command

sh kafka-run-class.sh kafka.admin.DeleteTopicCommand --topic yourtopic --zookeeper localhost:2181

First Add a Class called Win32.cs

public class Win32
{ 
    [DllImport("User32.Dll")]
    public static extern long SetCursorPos(int x, int y);

    [DllImport("User32.Dll")]
    public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);

    [StructLayout(LayoutKind.Sequential)]
    public struct POINT
    {
        public int x;
        public int y;

        public POINT(int X, int Y)
        {
            x = X;
            y = Y;
        }
    }
}

You can use it then like this:

Win32.POINT p = new Win32.POINT(xPos, yPos);

Win32.ClientToScreen(this.Handle, ref p);
Win32.SetCursorPos(p.x, p.y);

With any server-side language, you will have to emit the POST variables into javascript.

.NET

var my_post_variable = '<%= Request("post_variable") %>';

Just be careful of empty values. If the variable you attempt to emit is actually empty, you will get a javascript syntax error. If you know it's a string, you should wrap it in quotes. If it's an integer, you may want to test to see if it actually exists before writing the line to javascript.

We can use dplyr to select only numeric columns and purr to get sum for all columns. (can be used to get what ever value for all columns, such as mean, min, max, etc. )

library("dplyr")
library("purrr")

people %>%
    select_if(is.numeric) %>%
    map_dbl(sum)

Or another easy way by only using dplyr

library("dplyr")
people %>%
    summarize_if(is.numeric, sum, na.rm=TRUE)

Almost correctly.. Look at the joins, you are referring the wrong fields

SELECT student.firstname,
       student.lastname,
       exam.name,
       exam.date,
       grade.grade
  FROM grade
 INNER JOIN student ON student.studentId = grade.fk_studentId
 INNER JOIN exam ON exam.examId = grade.fk_examId
 ORDER BY exam.date

in 2020 if you want to set active class on element which has no [routerLink] - you can do simply:

<a
  (click)="bookmarks()"
  [class.active]="router.isActive('/string/path/'+you+'/need', false)" // <== you need this one. second argument 'false' - exact: true/false
  routerLinkActive="active"
  [routerLinkActiveOptions]="{ exact: true }"
>
  bookmarks
</a>

You need to do it like this,

void Yourfunction(List<DateTime> dates )
{

}

This should take care of space, tab and newline:

data = data.replaceAll("[ \t\n\r]*", " ");

Wouldn't it just be:

SELECT CURRENT_DATE - CHDLM FROM CHCART00 WHERE CHSTAT = '05';

That should return the number of days between the two dates, if I understand how date arithmetic works in DB2 correctly.

If CHDLM isn't a date you'll have to convert it to one. According to IBM the DATE() function would not be sufficient for the yyyymmdd format, but it would work if you can format like this: yyyy-mm-dd.

I think that your problem is that you are expecting np.append to add the column in-place, but what it does, because of how numpy data is stored, is create a copy of the joined arrays

Returns
-------
append : ndarray
    A copy of `arr` with `values` appended to `axis`.  Note that `append`
    does not occur in-place: a new array is allocated and filled.  If
    `axis` is None, `out` is a flattened array.

so you need to save the output all_data = np.append(...):

my_data = np.random.random((210,8)) #recfromcsv('LIAB.ST.csv', delimiter='\t')
new_col = my_data.sum(1)[...,None] # None keeps (n, 1) shape
new_col.shape
#(210,1)
all_data = np.append(my_data, new_col, 1)
all_data.shape
#(210,9)

Alternative ways:

all_data = np.hstack((my_data, new_col))
#or
all_data = np.concatenate((my_data, new_col), 1)

I believe that the only difference between these three functions (as well as np.vstack) are their default behaviors for when axis is unspecified:

• concatenate assumes axis = 0
• hstack assumes axis = 1 unless inputs are 1d, then axis = 0
• vstack assumes axis = 0 after adding an axis if inputs are 1d
• append flattens array

Based on your comment, and looking more closely at your example code, I now believe that what you are probably looking to do is add a field to a record array. You imported both genfromtxt which returns a structured array and recfromcsv which returns the subtly different record array (recarray). You used the recfromcsv so right now my_data is actually a recarray, which means that most likely my_data.shape = (210,) since recarrays are 1d arrays of records, where each record is a tuple with the given dtype.

So you could try this:

import numpy as np
from numpy.lib.recfunctions import append_fields
x = np.random.random(10)
y = np.random.random(10)
z = np.random.random(10)
data = np.array( list(zip(x,y,z)), dtype=[('x',float),('y',float),('z',float)])
data = np.recarray(data.shape, data.dtype, buf=data)
data.shape
#(10,)
tot = data['x'] + data['y'] + data['z'] # sum(axis=1) won't work on recarray
tot.shape
#(10,)
all_data = append_fields(data, 'total', tot, usemask=False)
all_data

SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE')

The column STATUS tells you whether the object is VALID or INVALID. If it is invalid, you have to try a recompile, ORACLE can't tell you if it will work before.

Try this:

 window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat="+elemA+"&lon="+elemB+"&setLatLon=Set";

To put a variable in a string enclose the variable in quotes and addition signs like this:

var myname = "BOB";
var mystring = "Hi there "+myname+"!"; 

Just remember that one rule!

In case the given answers still don't help you remove that, try this:

• Manually delete the line in require from composer.json

• Run composer update

Following Haskell code calculate the combination number and combinations at the same time, and thanks to Haskell's laziness, you can get one part of them without calculating the other.

import Data.Semigroup
import Data.Monoid

data Comb = MkComb {count :: Int, combinations :: [[Int]]} deriving (Show, Eq, Ord)

instance Semigroup Comb where
    (MkComb c1 cs1) <> (MkComb c2 cs2) = MkComb (c1 + c2) (cs1 ++ cs2)

instance Monoid Comb where
    mempty = MkComb 0 []

addElem :: Comb -> Int -> Comb
addElem (MkComb c cs) x = MkComb c (map (x :) cs)

comb :: Int -> Int -> Comb
comb n k | n < 0 || k < 0 = error "error in `comb n k`, n and k should be natural number"
comb n k | k == 0 || k == n = MkComb 1 [(take k [k-1,k-2..0])]
comb n k | n < k = mempty
comb n k = comb (n-1) k <> (comb (n-1) (k-1) `addElem` (n-1))

It works like:

*Main> comb 0 1
MkComb {count = 0, combinations = []}

*Main> comb 0 0
MkComb {count = 1, combinations = [[]]}

*Main> comb 1 1
MkComb {count = 1, combinations = [[0]]}

*Main> comb 4 2
MkComb {count = 6, combinations = [[1,0],[2,0],[2,1],[3,0],[3,1],[3,2]]}

*Main> count (comb 10 5)
252

There's a simple way to get rid of this restriction by using the datePicker component provided by jQuery.

1. Include jQuery and jQuery UI libraries (I'm still using an old one)

   • src="js/jquery-1.7.2.js"
   • src="js/jquery-ui-1.7.2.js"

2. Use the following snip

   $(function() {
        $( "#id_of_the_component" ).datepicker({ dateFormat: 'yy-mm-dd'}); 
   });
   

See jQuery UI DatePicker - Change Date Format if needed.

Probably is APC related.

For the people having this problem, please specify you .ini settings. Specifically your apc.mmap_file_mask setting.

For file-backed mmap, it should be set to something like:

apc.mmap_file_mask=/tmp/apc.XXXXXX

To mmap directly from /dev/zero, use:

apc.mmap_file_mask=/dev/zero

For POSIX-compliant shared-memory-backed mmap, use:

apc.mmap_file_mask=/apc.shm.XXXXXX

Have you tried the GNU make documentation? It has a whole section about conditionals with examples.

I prefer using Math.Round, Math.Floor, Math.Ceiling or Math.Truncate to explicitly set the rounding mode as appropriate.

Note that they all return Decimal as well - since Decimal has a larger range of values than an Int32, so you'll still need to cast (and check for overflow/underflow).

 checked {
   int i = (int)Math.Floor(d);
 }

You probably want ANSI color codes. Most *nix terminals support them.

The object of the exercise is to find the row that contains the information. When we get there, we can easily extract the required information.

Answer

$(".use-address").click(function() {
    var $item = $(this).closest("tr")   // Finds the closest row <tr> 
                       .find(".nr")     // Gets a descendent with class="nr"
                       .text();         // Retrieves the text within <td>

    $("#resultas").append($item);       // Outputs the answer
});

Now let's focus on some frequently asked questions in such situations.

How to find the closest row?

Using .closest():

var $row = $(this).closest("tr");

Using .parent():

You can also move up the DOM tree using .parent() method. This is just an alternative that is sometimes used together with .prev() and .next().

var $row = $(this).parent()             // Moves up from <button> to <td>
                  .parent();            // Moves up from <td> to <tr>

Getting all table cell <td> values

So we have our $row and we would like to output table cell text:

var $row = $(this).closest("tr"),       // Finds the closest row <tr> 
    $tds = $row.find("td");             // Finds all children <td> elements

$.each($tds, function() {               // Visits every single <td> element
    console.log($(this).text());        // Prints out the text within the <td>
});

VIEW DEMO

Getting a specific <td> value

Similar to the previous one, however we can specify the index of the child <td> element.

var $row = $(this).closest("tr"),        // Finds the closest row <tr> 
    $tds = $row.find("td:nth-child(2)"); // Finds the 2nd <td> element

$.each($tds, function() {                // Visits every single <td> element
    console.log($(this).text());         // Prints out the text within the <td>
});

VIEW DEMO

Useful methods

• .closest() - get the first element that matches the selector
• .parent() - get the parent of each element in the current set of matched elements
• .parents() - get the ancestors of each element in the current set of matched elements
• .children() - get the children of each element in the set of matched elements
• .siblings() - get the siblings of each element in the set of matched elements
• .find() - get the descendants of each element in the current set of matched elements
• .next() - get the immediately following sibling of each element in the set of matched elements
• .prev() - get the immediately preceding sibling of each element in the set of matched elements

I was looking for solution to this problem, until i found a very simple solution for accessing the session variables, assuming you use a .php file on server side. Hope it answers part of the question :

access session value

<script type="text/javascript">        
    var value = <?php echo $_SESSION['key']; ?>;
    console.log(value);
</script>

Edit : better example below, which you can try on phpfiddle.org, at the "codespace" tab

<!DOCTYPE html>
<html>
 <head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <?php
    $_SESSION['key'] = 10;
    $i = $_SESSION['key'];
  ?>
 </head>
 <body>
  <p id="affichage">hello</p>

  <script type="text/javascript">
    var value =  <?php echo $i; ?>;
    $("#affichage").html(value);   
  </script>

 </body>
</html>

set session value

pass it a variable of whatever, you may want to. eg,

$you = 13;
$_SESSION['user_id'] = $you;

This should work, tho' not tested it.

Since Bootstrap 3 doesn't have a style for checkboxes I found a custom made that goes really well with Bootstrap style.

Custom icons

You can choose your own icon between the ones from Bootstrap or Font Awesome by changing [icon name] with your icon.

<span class="cr"><i class="cr-icon [icon name]"></i>

For example:

• glyphicon glyphicon-remove for Bootstrap, or
• fa fa-bullseye for Font Awesome

NPM in 2019

npm build no longer exists. You must call npm run build now. More info below.

TLDR;

npm install: installs dependencies, then calls the install from the package.json scripts field.

npm run build: runs the build field from the package.json scripts field.

NPM Scripts Field

https://docs.npmjs.com/misc/scripts

There are many things you can put into the npm package.json scripts field. Check out the documentation link above more above the lifecycle of the scripts - most have pre and post hooks that you can run scripts before/after install, publish, uninstall, test, start, stop, shrinkwrap, version.

To Complicate Things

• npm install is not the same as npm run install
• npm install installs package.json dependencies, then runs the package.json scripts.install
  • (Essentially calls npm run install after dependencies are installed.
• npm run install only runs the package.json scripts.install, it will not install dependencies.
• npm build used to be a valid command (used to be the same as npm run build) but it no longer is; it is now an internal command. If you run it you'll get: npm WARN build npm build called with no arguments. Did you mean to npm run-script build? You can read more on the documentation: https://docs.npmjs.com/cli/build

Extra Notes

There are still two top level commands that will run scripts, they are:

• npm start which is the same as npm run start
• npm test ==> npm run test

You can use templated interfaces like this:

interface Map<T> {

Many of us know that the Popular Method of Escaping Single Quotes is by Doubling them up easily like below.

PRINT 'It''s me, Arul.';

we are going to look on some other alternate ways of escaping the single quotes.

1.UNICODE Characters

39 is the UNICODE character of Single Quote. So we can use it like below.

PRINT 'Hi,it'+CHAR(39)+'s Arul.';
PRINT 'Helo,it'+NCHAR(39)+'s Arul.';

2.QUOTED_IDENTIFIER

Another simple and best alternate solution is to use QUOTED_IDENTIFIER. When QUOTED_IDENTIFIER is set to OFF, the strings can be enclosed in double quotes. In this scenario, we don’t need to escape single quotes. So,this way would be very helpful while using lot of string values with single quotes. It will be very much helpful while using so many lines of INSERT/UPDATE scripts where column values having single quotes.

SET QUOTED_IDENTIFIER OFF;
PRINT "It's Arul."
SET QUOTED_IDENTIFIER ON;

CONCLUSION

The above mentioned methods are applicable to both AZURE and On Premises .

Emil's answer is correct, but it's my understanding that inet_ntoa is deprecated and that instead you should use inet_ntop. If you are using IPv4, cast your struct sockaddr to sockaddr_in. Your code will look something like this:

struct addrinfo *res;   // populated elsewhere in your code
struct sockaddr_in *ipv4 = (struct sockaddr_in *)res->ai_addr;
char ipAddress[INET_ADDRSTRLEN];
inet_ntop(AF_INET, &(ipv4->sin_addr), ipAddress, INET_ADDRSTRLEN);

printf("The IP address is: %s\n", ipAddress);

Take a look at this great resource for more explanation, including how to do this for IPv6 addresses.

in my case this error occured if i use table without header

              <thead>
                   <tr>
                       <th>example</th>
                  </tr>
              </thead>

I think what you want is something like:

=INDEX(B:B,MATCH(C2,A:A,0))  

I should mention that MATCH checks the position at which the value can be found within A:A (given the 0, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B.

Os

You can list all files in the current directory using os.listdir:

import os
for filename in os.listdir(os.getcwd()):
   with open(os.path.join(os.getcwd(), filename), 'r') as f: # open in readonly mode
      # do your stuff

Glob

Or you can list only some files, depending on the file pattern using the glob module:

import glob
for filename in glob.glob('*.txt'):
   with open(os.path.join(os.cwd(), filename), 'r') as f: # open in readonly mode
      # do your stuff

It doesn't have to be the current directory you can list them in any path you want:

path = '/some/path/to/file'
for filename in glob.glob(os.path.join(path, '*.txt')):
   with open(os.path.join(os.getcwd(), filename), 'r') as f: # open in readonly mode
      # do your stuff

Pipe Or you can even use the pipe as you specified using fileinput

import fileinput
for line in fileinput.input():
    # do your stuff

And then use it with piping:

ls -1 | python parse.py

All hidden-*-up, hidden-* classes doesn't work for me, so I'm adding self-made hidden class before visible-*(which works for current bootstrap version). It is very useful if you need to show div only for one screen, and hide for all others.

CSS:

.hidden {display:none;}

HTML:

<div class="col-xs-12 hidden visible-xs visible-sm">
   <img src="photo.png" style="width:100%">
</div>

I have tried like this

git rm --cached -r * -f

And it is working for me.

Check for @ and . and then send an email for them to verify.

I still can't use my .name email address on 20% of the sites on the internet because someone screwed up their email validation, or because it predates the new addresses being valid.

I've created my own formatting utility. Which is extremely fast at processing the formatting along with giving you many features :)

It supports:

• Comma Formatting E.g. 1234567 becomes 1,234,567.
• Prefixing with "Thousand(K),Million(M),Billion(B),Trillion(T)".
• Precision of 0 through 15.
• Precision re-sizing (Means if you want 6 digit precision, but only have 3 available digits it forces it to 3).
• Prefix lowering (Means if the prefix you choose is too large it lowers it to a more suitable prefix).

The code can be found here. You call it like this:

public static void main(String[])
{
   int settings = ValueFormat.COMMAS | ValueFormat.PRECISION(2) | ValueFormat.MILLIONS;
   String formatted = ValueFormat.format(1234567, settings);
}

I should also point out this doesn't handle decimal support, but is very useful for integer values. The above example would show "1.23M" as the output. I could probably add decimal support maybe, but didn't see too much use for it since then I might as well merge this into a BigInteger type of class that handles compressed char[] arrays for math computations.

Long ago it was impossible to reliably get the list of processes locking a file because Windows simply did not track that information. To support the Restart Manager API, that information is now tracked.

I put together code that takes the path of a file and returns a List<Process> of all processes that are locking that file.

Using from Limited Permission (e.g. IIS)

This call accesses the registry. If the process does not have permission to do so, you will get ERROR_WRITE_FAULT, meaning An operation was unable to read or write to the registry. You could selectively grant permission to your restricted account to the necessary part of the registry. It is more secure though to have your limited access process set a flag (e.g. in the database or the file system, or by using an interprocess communication mechanism such as queue or named pipe) and have a second process call the Restart Manager API.

Granting other-than-minimal permissions to the IIS user is a security risk.

This is an online database but you can try with the stackoverflow database: https://data.stackexchange.com/stackoverflow/query/new

You also can download its dumps here:

https://archive.org/download/stackexchange

You could use the xpath :

//div[@class="measure-tab" and .//span[contains(., "someText")]]

Input :

<root>
<div class="measure-tab">
  <td> someText</td>
</div>
<div class="measure-tab">
  <div>
    <div2>
       <span>someText2</span>
   </div2>
  </div>
</div>
</root>

Output :

    Element='<div class="measure-tab">
  <div>
    <div2>
      <span>someText2</span>
    </div2>
  </div>
</div>'

Nobody seems to implemented an extension method. With the help of @CMS's answer:

Working and improved full source example is here: Gist Link

namespace ExtensionMethods {
    using System;
    using System.Globalization;

    public static class DateTimeExtensions {
        public static DateTime ToDateTime(this string s, 
                  string format = "ddMMyyyy", string cultureString = "tr-TR") {

                throw;
            } catch (CultureNotFoundException) {

            }

                format: "dd/MMMM/yyyy"); 
         // Weird :) I supposed dd/yyyy/MMMM but that did not work !?$^&*

            System.Diagnostics.Debug.Assert(

        }

}

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

EXEC sp_serveroption 'YOURSERVERNAME', 'DATA ACCESS', TRUE

SELECT  *
INTO    #tmpTable
FROM    OPENQUERY(YOURSERVERNAME, 'EXEC db.schema.sproc 1')

In case you have composite primary key, do like this- ALTER TABLE table_name DROP PRIMARY KEY,ADD PRIMARY KEY (col_name1, col_name2);

You can define ASCII as all characters that have a decimal value of 0 - 127 (0x00 - 0x7F) and find columns with non-ASCII characters using the following query

SELECT * FROM TABLE WHERE NOT HEX(COLUMN) REGEXP '^([0-7][0-9A-F])*$';

This was the most comprehensive query I could come up with.

I too had the same problem.

The solution for me was to add following in the pom.xml as suggested here.

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.0.2</version>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
</build>

If you are using a modern browser there's a simple solution.

First, attach a template variable to the input.

<input type="date" #date />

Then pass the variable into your receiving method.

<button (click)="submit(date)"></button>

In your controller just accept the parameter as type HTMLInputElement and use the method valueAsDate on the HTMLInputElement.

submit(date: HTMLInputElement){
    console.log(date.valueAsDate);
}

You can then manipulate the date anyway you would a normal date.

You can also set the value of your <input [value]= "..."> as you would normally.

Personally, as someone trying to stay true to the unidirectional data flow, i try to stay away from two way data binding in my components.

You need to add a reference inside the window tag. Something like:

xmlns:controls="clr-namespace:YourCustomNamespace.Controls;assembly=YourAssemblyName"

(When you add xmlns:controls=" intellisense should kick in to make this bit easier)

Then you can add the control with:

<controls:CustomControlClassName ..... />

with this method, using SYSTEM_UI_FLAG_IMMERSIVE_STICKY the full screen come back with one tap without any implementation. Just copy past this method below and call it where you want in your activity. More details here

private void hideSystemUI() {
    getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE
                    // Set the content to appear under the system bars so that the
                    // content doesn't resize when the system bars hide and show.
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    // Hide the nav bar and status bar
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN);
}

This is right from the manual:

http://docs.python.org/2/library/bisect.html

8.5.1. Searching Sorted Lists

The above bisect() functions are useful for finding insertion points but can be tricky or awkward to use for common searching tasks. The following five functions show how to transform them into the standard lookups for sorted lists:

def index(a, x):
    'Locate the leftmost value exactly equal to x'
    i = bisect_left(a, x)
    if i != len(a) and a[i] == x:
        return i
    raise ValueError

So with the slight modification your code should be:

def index(a, x):
    'Locate the leftmost value exactly equal to x'
    i = bisect_left(a, x)
    if i != len(a) and a[i] == x:
        return i
    return -1

Maybe you can use a file, write to file inside function, read from file after it. I have changed e to an array. In this example blanks are used as separator when reading back the array.

#!/bin/bash

declare -a e
e[0]="first"
e[1]="secondddd"

function test1 () {
 e[2]="third"
 e[1]="second"
 echo "${e[@]}" > /tmp/tempout
 echo hi
}

ret=$(test1)

echo "$ret"

read -r -a e < /tmp/tempout
echo "${e[@]}"
echo "${e[0]}"
echo "${e[1]}"
echo "${e[2]}"

Output:

hi
first second third
first
second
third

O (n log n) is famously the upper bound on how fast you can sort an arbitrary set (assuming a standard and not highly parallel computing model).

Create the database, with Script Database as... CREATE To

Within SSMS on the source server, use the export wizard with the destination server database as the destination.

• Source instance > YourDatabase > Tasks > Export data
• Data Soure = SQL Server Native Client
  • Validate/enter Server & Database
• Destination = SQL Server Native Client
  • Validate/enter Server & Database
• Follow through wizard

This should work:

The default behaviour of Newtonsoft.Json is going to find the public constructors. If your default constructor is only used in containing class or the same assembly, you can reduce the access level to protected or internal so that Newtonsoft.Json will pick your desired public constructor.

Admittedly, this solution is rather very limited to specific cases.

internal Result() { }

public Result(int? code, string format, Dictionary<string, string> details = null)
{
    Code = code ?? ERROR_CODE;

Fix the typos in your code ("document" is spelled wrong on lines 3 & 4 of your function, and change the onclick event handler to read: onclick="show_update_profile()" and then you'll be fine. You should really follow jmort's advice and simply set up 2 css classes that you switch between in javascript -- it would make your life a lot easier and save yourself from all the extra typing. The typos you've committed are a perfect example of why this is the better approach.

For brownie points, you should also check out element.addEventListener for assigning event handlers to your elements.

Here is my attempt. It has some common 'stupidity' checks built in, making sure you don't try to set or get a member which isn't available.

You could move those 'property_exists' checks to __set and __get respectively and call them directly within magic().

<?php

class Foo {
    public $Name;

    public function magic($member, $value = NULL) {
        if ($value != NULL) {
            if (!property_exists($this, $member)) {
                trigger_error('Undefined property via magic(): ' .
                    $member, E_USER_ERROR);
                return NULL;
            }
            $this->$member = $value;
        } else {
            if (!property_exists($this, $member)) {
                trigger_error('Undefined property via magic(): ' .
                    $member, E_USER_ERROR);
                return NULL;
            }
            return $this->$member;
        }
    }
};

$f = new Foo();

$f->magic("Name", "Something");
echo $f->magic("Name") , "\n";

// error
$f->magic("Fame", "Something");
echo $f->magic("Fame") , "\n";

?>

You can use the opt(int) method and use a classical for loop.

You could create another object that dispatches calls to magic methods to the underlying objects. Here's how you'd handle __get, but to get it working fully you'd have to override all the relevant magic methods. You'll probably find syntax errors since I just entered it off the top of my head.

class Compositor {
  private $obj_a;
  private $obj_b;

  public function __construct($obj_a, $obj_b) {
    $this->obj_a = $obj_a;
    $this->obj_b = $obj_b;
  }

  public function __get($attrib_name) {
    if ($this->obj_a->$attrib_name) {
       return $this->obj_a->$attrib_name;
    } else {
       return $this->obj_b->$attrib_name;
    }
  }
}

Good luck.

If you are looking for a intuition based answer I would like to put up two interpretations for you.

1. Imagine a very high hill with a very broad base as well. To reach the top of the hill there are two ways: one is a dedicated pathway going spirally around the hill reaching at the top, the other: small terrace like carvings cut out to provide a staircase. Now if the first way is reaching in linear time O(n), the second one is O(log n).

2. Imagine an algorithm, which accepts an integer, n as input and completes in time proportional to n then it is O(n) or theta(n) but if it runs in time proportion to the number of digits or the number of bits in the binary representation on number then the algorithm runs in O(log n) or theta(log n) time.

Using slice

You can use slice(0,index) + str + slice(index). Or you can create a method for it.

String.prototype.insertAt = function(index,str){_x000D_
  return this.slice(0,index) + str + this.slice(index)_x000D_
}_x000D_
console.log("foo bar".insertAt(4,'baz ')) //foo baz bar

Splice method for Strings

You can split() the main string and add then use normal splice()

String.prototype.splice = function(index,del,...newStrs){_x000D_
  let str = this.split('');_x000D_
  str.splice(index,del,newStrs.join('') || '');_x000D_
  return str.join('');_x000D_
}_x000D_
_x000D_
_x000D_
 var txt1 = "foo baz"_x000D_
_x000D_
//inserting single string._x000D_
console.log(txt1.splice(4,0,"bar ")); //foo bar baz_x000D_
_x000D_
_x000D_
//inserting multiple strings_x000D_
console.log(txt1.splice(4,0,"bar ","bar2 ")); //foo bar bar2 baz_x000D_
_x000D_
_x000D_
//removing letters_x000D_
console.log(txt1.splice(1,2)) //f baz_x000D_
_x000D_
_x000D_
//remving and inseting atm_x000D_
console.log(txt1.splice(1,2," bar")) //f bar baz

Applying splice() at multiple indexes

The method takes an array of arrays each element of array representing a single splice().

String.prototype.splice = function(index,del,...newStrs){_x000D_
  let str = this.split('');_x000D_
  str.splice(index,del,newStrs.join('') || '');_x000D_
  return str.join('');_x000D_
}_x000D_
_x000D_
_x000D_
String.prototype.mulSplice = function(arr){_x000D_
  str = this_x000D_
  let dif = 0;_x000D_
  _x000D_
  arr.forEach(x => {_x000D_
    x[2] === x[2] || [];_x000D_
    x[1] === x[1] || 0;_x000D_
    str = str.splice(x[0] + dif,x[1],...x[2]);_x000D_
    dif += x[2].join('').length - x[1];_x000D_
  })_x000D_
  return str;_x000D_
}_x000D_
_x000D_
let txt = "foo bar baz"_x000D_
_x000D_
//Replacing the 'foo' and 'bar' with 'something1' ,'another'_x000D_
console.log(txt.splice(0,3,'something'))_x000D_
console.log(txt.mulSplice(_x000D_
[_x000D_
[0,3,["something1"]],_x000D_
[4,3,["another"]]_x000D_
]_x000D_
_x000D_
))

Using dplyr:

require(dplyr)    
df <- data.frame(A = c(1, 1, 2, 3, 3), B = c(2, 3, 3, 5, 6))
df %>% group_by(A) %>% summarise(B = sum(B))

## Source: local data frame [3 x 2]
## 
##   A  B
## 1 1  5
## 2 2  3
## 3 3 11

With sqldf:

library(sqldf)
sqldf('SELECT A, SUM(B) AS B FROM df GROUP BY A')

I ran into this issue as well, but in order to use a safe pipe in my angular module, I installed the safe-pipe npm package, which you can find here. FYI, this worked in Angular 9.1.3, I haven't tried this in any other versions of Angular. Here's how you add it step by step:

1. Install the package via npm install safe-pipe or yarn add safe-pipe. This will store a reference to it in your dependencies in the package.json file, which you should already have from starting a new Angular project.

2. Add SafePipeModule module to NgModule.imports in your Angular module file like so:

   import { SafePipeModule } from 'safe-pipe';
   
   @NgModule({
       imports: [ SafePipeModule ]
   })
   export class AppModule { }
   
   

3. Add the safe pipe to an element in the template for the Angular component you are importing into your NgModule this way:

<element [property]="value | safe: sanitizationType"></element>

4. Here are some specific examples of the safePipe in an html element:

<div [style.background-image]="'url(' + pictureUrl + ')' | safe: 'style'" class="pic bg-pic"></div>
<img [src]="pictureUrl | safe: 'url'" class="pic" alt="Logo">
<iframe [src]="catVideoEmbed | safe: 'resourceUrl'" width="640" height="390"></iframe>
<pre [innerHTML]="htmlContent | safe: 'html'"></pre>

How about adding a space in the pattern attribute like pattern="[a-zA-Z0-9 ]+". If you want to support any kind of space try pattern="[a-zA-Z0-9\s]+"

One way to get this error in Eclipse :

1. Define a class A in src/test/java.
2. Define another class B in src/main/java that uses class A.

Result : Eclipse will compile the code, but maven will give "Cannot find symbol".

Underlying cause : Eclipse is using a combined build path for the main and test trees. Unfortunately, it does not support using different build paths for different parts of an Eclipse project, which is what Maven requires.

Solution :

1. Don't define your dependencies that way; i.e. don't make this mistake.
2. Regularly build your codebase using Maven so that you pick up this mistake early. One way to do that is to use a CI server.

The key is to keep the declarations of the variable in the header file and source file the same.

I use this trick

------sample.c------
#define sample_c
#include sample.h

(rest of sample .c)

------sample.h------
#ifdef sample_c
#define EXTERN
#else
#define EXTERN extern
#endif

EXTERN int x;

Sample.c is only compiled once and it defines the variables. Any file that includes sample.h is only given the "extern" of the variable; it does allocate space for that variable.

When you change the type of x, it will change for everybody. You won't need to remember to change it in the source file and the header file.

My preferred option is very fast, I sampled a tab-delimited data file with 13 columns, 23.1M rows, 2.0GB uncompressed.

# randomly sample select 5% of lines in file
# including header row, exclude blank lines, new seed

time \
awk 'BEGIN  {srand()} 
     !/^$/  { if (rand() <= .05 || FNR==1) print > "data-sample.txt"}' data.txt

# awk  tsv004  3.76s user 1.46s system 91% cpu 5.716 total

You need to copy Views/Web.config to /Shared. This will tell Razor to use the MVC base type & parser. You can read more here: http://blog.slaks.net/2011/02/dissecting-razor-part-3-razor-and-mvc.html

All answers are great, but if you have multiple checkboxes in a form with the same name and you want to post the status of each checkbox. Then i have solved this problem by placing a hidden field with the checkbox (name related to what i want).

<input type="hidden" class="checkbox_handler" name="is_admin[]" value="0" />
<input type="checkbox" name="is_admin_ck[]" value="1" />

then control the change status of checkbox by below jquery code:

$(documen).on("change", "input[type='checkbox']", function() {
    var checkbox_val = ( this.checked ) ? 1 : 0;
    $(this).siblings('input.checkbox_handler').val(checkbox_val);
});

now on change of any checkbox, it will change the value of related hidden field. And on server you can look only to hidden fields instead of checkboxes.

Hope this will help someone have this type of problem. cheer :)

All other answers are useful but they may not help you in case nginx is not on PATH so you're getting command not found when trying to run nginx:

I have nginx 1.2.1 on Debian 7 Wheezy, the nginx executable is not on PATH, so I needed to locate it first. It was already running, so using ps aux | grep nginx I have found out that it's located on /usr/sbin/nginx, therefore I needed to run /usr/sbin/nginx -t.

If you want to use a non-default configuration file (i.e. not /etc/nginx/nginx.conf), run it with the -c parameter: /usr/sbin/nginx -c <path-to-configuration> -t.

You may also need to run it as root, otherwise nginx may not have permissions to open for example logs, so the command would fail.

I couldn't get any of these to work inside my placeholder attribute, so I used xml special character.

<input type="text" placeholder="fex: firstname&#64;lastname.com"/>

It is very simple in kotlin. Use ColorStateList to change card view colour

   var color = R.color.green;
   cardView.setCardBackgroundColor(context.colorList(color));

A kotlin extension of ColorStateList:

fun Context.colorList(id: Int): ColorStateList {
    return ColorStateList.valueOf(ContextCompat.getColor(this, color))
}

I found this. Using:

galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

for one of the intents shows the user the option of selecting 'documents' in Android 4, which I found very confusing. Using this instead shows the 'gallery' option:

Intent pickIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

Virtual memory is, among other things, an abstraction to give the programmer the illusion of having infinite memory available on their system.

Virtual memory mappings are made to correspond to actual physical addresses. The operating system creates and deals with these mappings - utilizing the page table, among other data structures to maintain the mappings. Virtual memory mappings are always found in the page table or some similar data structure (in case of other implementations of virtual memory, we maybe shouldn't call it the "page table"). The page table is in physical memory as well - often in kernel-reserved spaces that user programs cannot write over.

Virtual memory is typically larger than physical memory - there wouldn't be much reason for virtual memory mappings if virtual memory and physical memory were the same size.

Only the needed part of a program is resident in memory, typically - this is a topic called "paging". Virtual memory and paging are tightly related, but not the same topic. There are other implementations of virtual memory, such as segmentation.

I could be assuming wrong here, but I'd bet the things you are finding hard to wrap your head around have to do with specific implementations of virtual memory, most likely paging. There is no one way to do paging - there are many implementations and the one your textbook describes is likely not the same as the one that appears in real OSes like Linux/Windows - there are probably subtle differences.

I could blab a thousand paragraphs about paging... but I think that is better left to a different question targeting specifically that topic.

One can access the "Find in Files" window via the drop-down menu selection and search all files in the Entire Solution: Edit > Find and Replace > Find in Files

Other, alternative is to open the "Find in Files" window via the "Standard Toolbars" button as highlighted in the below screen-short:

The Expires entity-header field gives the date/time after which the response is considered stale.The Cache-control:maxage field gives the age value (in seconds) bigger than which response is consider stale.

Althought above header field give a mechanism to client to decide whether to send request to the server. In some condition, the client send a request to sever and the age value of response is bigger then the maxage value ,dose it means server needs to send the resource to client? Maybe the resource never changed.

In order to resolve this problem, HTTP1.1 gives last-modifided head. The server gives the last modified date of the response to client. When the client need this resource, it will send If-Modified-Since head field to server. If this date is before the modified date of the resouce, the server will sends the resource to client and gives 200 code.Otherwise,it will returns 304 code to client and this means client can use the resource it cached.

You can also do this:

var x = new object[] {
    new { firstName = "john", lastName = "walter" },
    new { brand = "BMW" }
};

And if they are the same anonymous type (firstName and lastName), you won't need to cast as object.

var y = new [] {
    new { firstName = "john", lastName = "walter" },
    new { firstName = "jill", lastName = "white" }
};

Solution 1)

delete from emp
where rowid not in
(select max(rowid) from emp group by empno);

Solution 2)

delete from emp where rowid in
               (
                 select rid from
                  (
                    select rowid rid,
                      row_number() over(partition by empno order by empno) rn
                      from emp
                  )
                where rn > 1
               );

Solution 3)

delete from emp e1
         where rowid not in
          (select max(rowid) from emp e2
           where e1.empno = e2.empno ); 

Sure, this can be done using profiles. You can do something like the following in your parent pom.xml.

  ...
   <modules>
      <module>module1</module>
      <module>module2</module>  
      ...
  </modules>
  ...
  <profiles>
     <profile>
       <id>ci</id>
          <modules>
            <module>module1</module>
            <module>module2</module>
            ...
            <module>module-integration-test</module>
          </modules> 
      </profile>
  </profiles>
 ...

In your CI, you would run maven with the ci profile, i.e. mvn -P ci clean install

In my case error is because i have put ">>" twice

mongodump --db=$DB_NAME --collection=$col --out=$BACKUP_LOCATION/$DB_NAME-$BACKUP_DATE >> >> $LOG_PATH

i just correct it as

mongodump --db=$DB_NAME --collection=$col --out=$BACKUP_LOCATION/$DB_NAME-$BACKUP_DATE >> $LOG_PATH

• Pass a string to RegExp or create a regex using the // syntax
• Call regex.test(string), not string.test(regex)

So

jQuery(function () {
    $(".mail").keyup(function () {
        var VAL = this.value;

        var email = new RegExp('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$');

        if (email.test(VAL)) {
            alert('Great, you entered an E-Mail-address');
        }
    });
});

Firstly, understand that DateTime objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime objects without formatting them.

To compare an input date with DateTime.Now, you need to first parse the input into a date and then compare just the Year/Month/Day portions:

DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
    throw new ArgumentException("Input string not in the correct format.");

if(inputDate.Date == DateTime.Now.Date) {
    // Same date!
}

Browsers with HTML5 support has files property for input type. This will of course not work in older IE versions.

var inpFiles = document.getElementById('#fileID');
for (var i = 0; i < inpFiles.files.length; ++i) {
    var size = inpFiles.files.item(i).size;
    alert("File Size : " + size);
}

if ([statusString isEqualToString:@"Wrong"]) {
    // do something
}

I had a similar issue and solved with the following steps after connecting the device via USB:

1. turn on developer options on the android device.
2. enable check box for stay awake.
3. enable check box for USB debugging.
4. open cmd
5. got to platform tools adt tools here https://developer.android.com/studio.
6. adb kill-server
7. adb start-server
8. adb devices

Now we can see attached devices.

This code shows how to use a java.text.SimpleDateFormat to parse a java.util.Date from a String:

String str = "Jun 13 2003 23:11:52.454 UTC";
SimpleDateFormat df = new SimpleDateFormat("MMM dd yyyy HH:mm:ss.SSS zzz");
Date date = df.parse(str);
long epoch = date.getTime();
System.out.println(epoch); // 1055545912454

Date.getTime() returns the epoch time in milliseconds.

Thread.interrupt() sets the interrupted status/flag of the target thread. Then code running in that target thread MAY poll the interrupted status and handle it appropriately. Some methods that block such as Object.wait() may consume the interrupted status immediately and throw an appropriate exception (usually InterruptedException)

Interruption in Java is not pre-emptive. Put another way both threads have to cooperate in order to process the interrupt properly. If the target thread does not poll the interrupted status the interrupt is effectively ignored.

Polling occurs via the Thread.interrupted() method which returns the current thread's interrupted status AND clears that interrupt flag. Usually the thread might then do something such as throw InterruptedException.

EDIT (from Thilo comments): Some API methods have built in interrupt handling. Of the top of my head this includes.

• Object.wait(), Thread.sleep(), and Thread.join()
• Most java.util.concurrent structures
• Java NIO (but not java.io) and it does NOT use InterruptedException, instead using ClosedByInterruptException.

EDIT (from @thomas-pornin's answer to exactly same question for completeness)

Thread interruption is a gentle way to nudge a thread. It is used to give threads a chance to exit cleanly, as opposed to Thread.stop() that is more like shooting the thread with an assault rifle.

Or use directly the InputStream of the resource using the absolute CLASSPATH path (starting with the / slash character):

getClass().getResourceAsStream("/com/path/to/file.txt");

Or relative CLASSPATH path (when the class you are writing is in the same Java package as the resource file itself, i.e. com.path.to):

getClass().getResourceAsStream("file.txt");

Might want to include the old A: and B: drives as you never know who might be using them! I got tired of USB drives bumping my two SDHC drives that are just for Readyboost. I had been assigning them to High letters Z: Y: with a utility that will assign drive letters to devices as you wish. I wondered.... Can I make a Readyboost drive letter A: ? YES! Can I put my second SDHC drive letter as B: ? YES!

I've used Floppy Drives back in the day, never thought that A: or B: would come in handy for Readyboost.

My point is, don't assume A: & B: will not be used by anyone for anything You might even find the old SUBST command being used!

<span id="span">HOI</span>
<script>
   var span = document.getElementById("span");
   console.log(span);

   span.style.fontSize = "25px";
   span.innerHTML = "String";
</script>

You have two errors in your code:

1. document.getElementById - This retrieves the element with an Id that is "span", you did not specify an id on the span-element.

2. Capitals in Javascript - Also you forgot the capital of Size.

Joseph's answer pointed out ISNUMERIC also handles scientific notation like '1.3e+3' but his answer doesn't handle this format of number.

Casting to a money or float first handles both the currency and scientific issues:

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[TryConvertInt]') AND type in (N'FN', N'IF', N'TF', N'FS', N'FT'))
DROP FUNCTION [dbo].[TryConvertInt]
GO

CREATE FUNCTION dbo.TryConvertInt(@Value varchar(18))
RETURNS bigint
AS
BEGIN
    DECLARE @IntValue bigint;

    IF (ISNUMERIC(@Value) = 1)
        IF (@Value like '%e%')
            SET @IntValue = CAST(Cast(@Value as float) as bigint);
        ELSE
            SET @IntValue = CAST(CAST(@Value as money) as bigint);
    ELSE
        SET @IntValue = NULL;

    RETURN @IntValue;
END

The function will fail if the number is bigger than a bigint.

If you want to return a different default value, leave this function so it is generic and replace the null afterwards:

SELECT IsNull(dbo.TryConvertInt('nan') , 1000);

Sharing data between controllers is what Factories/Services are very good for. In short, it works something like this.

var app = angular.module('myApp', []);

app.factory('items', function() {
    var items = [];
    var itemsService = {};

    itemsService.add = function(item) {
        items.push(item);
    };
    itemsService.list = function() {
        return items;
    };

    return itemsService;
});

function Ctrl1($scope,items) {
    $scope.list = items.list; 
}

function Ctrl2($scope, items) {
    $scope.add = items.add;
}

You can see a working example in this fiddle: http://jsfiddle.net/mbielski/m8saa/

You can also use create_function to create a function as a variable and pass it around. Though, I like the feeling of anonymous functions better. Go zombat.

This is just an add-on to the solution in case you want to compute not only unique values but other aggregate functions:

df.groupby(['group']).agg(['min','max','count','nunique'])

Hope you find it useful

Here's how you can mock your FileConnection

Mock<IFileConnection> fileConnection = new Mock<IFileConnection>(
                                                           MockBehavior.Strict);
fileConnection.Setup(item => item.Get(It.IsAny<string>,It.IsAny<string>))
              .Throws(new IOException());

Then instantiate your Transfer class and use the mock in your method call

Transfer transfer = new Transfer();
transfer.GetFile(fileConnection.Object, someRemoteFilename, someLocalFileName);

Update:

First of all you have to mock your dependencies only, not the class you are testing(Transfer class in this case). Stating those dependencies in your constructor make it easy to see what services your class needs to work. It also makes it possible to replace them with fakes when you are writing your unit tests. At the moment it's impossible to replace those properties with fakes.

Since you are setting those properties using another dependency, I would write it like this:

public class Transfer
{
    public Transfer(IInternalConfig internalConfig)
    {
        source = internalConfig.GetFileConnection("source");
        destination = internalConfig.GetFileConnection("destination");
    }

    //you should consider making these private or protected fields
    public virtual IFileConnection source { get; set; }
    public virtual IFileConnection destination { get; set; }

    public virtual void GetFile(IFileConnection connection, 
        string remoteFilename, string localFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void PutFile(IFileConnection connection, 
        string localFilename, string remoteFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void TransferFiles(string sourceName, string destName)
    {
        var tempName = Path.GetTempFileName();
        GetFile(source, sourceName, tempName);
        PutFile(destination, tempName, destName);
    }
}

This way you can mock internalConfig and make it return IFileConnection mocks that does what you want.

I wrote next method as my solution (I hadn't any load indicator):

public static void waitForAjax(WebDriver driver, String action) {
       driver.manage().timeouts().setScriptTimeout(5, TimeUnit.SECONDS);
       ((JavascriptExecutor) driver).executeAsyncScript(
               "var callback = arguments[arguments.length - 1];" +
                       "var xhr = new XMLHttpRequest();" +
                       "xhr.open('POST', '/" + action + "', true);" +
                       "xhr.onreadystatechange = function() {" +
                       "  if (xhr.readyState == 4) {" +
                       "    callback(xhr.responseText);" +
                       "  }" +
                       "};" +
                       "xhr.send();");
}

Then I jsut called this method with actual driver. More description in this post.

If anyone finds their way here with the same problem I was having, my problem was that I was missing the <dependencyManagement> tags around dependencies I had copied from the child pom.

A really cool usage is:

x = foo ? 1 :
    bar ? 2 :
    baz ? 3 :
          4;

it should be sending a POST if you provide a data parameter (like you are doing):

from the docs: "the HTTP request will be a POST instead of a GET when the data parameter is provided"

so.. add some debug output to see what's up from the client side.

you can modify your code to this and try again:

import urllib
import urllib2

url = 'http://myserver/post_service'
opener = urllib2.build_opener(urllib2.HTTPHandler(debuglevel=1))
data = urllib.urlencode({'name' : 'joe',
                         'age'  : '10'})
content = opener.open(url, data=data).read()

For PostgreSQL:

UPDATE Sales_Import SI
SET AccountNumber = RAN.AccountNumber
FROM RetrieveAccountNumber RAN
WHERE RAN.LeadID = SI.LeadID; 

One way would be with sed. For example:

echo $name | sed -e 's?http://www\.??'

Normally the sed regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:

echo ${name#http://www.}

(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)

I just want to expand on queen3's suggestion, applying the following does the trick:

editoptions: { 
              dataInit: function(element) { 
                          $(element).attr("readonly", "readonly"); 
                        } 
             }

Scenario #1:

• Field must be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
        {  name:'providerUserId',
               index:'providerUserId', 
               width:100,editable:true, 
               editrules:{required:true}, 
               editoptions:{ 
                            dataInit: function(element) { 
                                  jq(element).attr("readonly", "readonly"); 
                             } 
                           }
            },
],

The providerUserId is visible in the grid and visible when editing the form. But you cannot edit the contents.

Scenario #2:

• Field must not be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
           {name:'providerUserId',
            index:'providerUserId', 
            width:100,editable:true, 
            editrules:{
                         required:true, 
                         edithidden:true
                      },
            hidden:true, 
            editoptions:{ 
                  dataInit: function(element) {                     
                             jq(element).attr("readonly", "readonly"); 
                          } 
                     }
         },
        ]

Notice in both instances I'm using jq to reference jquery, instead of the usual $. In my HTML I have the following script to modify the variable used by jQuery:

<script type="text/javascript">
    var jq = jQuery.noConflict();
</script>

This is a late answer, but I had the same problem, but the answer was different.

In my case, there was a sourceURL reference in my code:

//@ sourceURL=/Scripts/test.js

When this Javascript file is minified and loaded by the browser, it normally tells Chrome Dev Tools where the unminified version is.

However, if you are debugging the unminified version and this line exists, Chrome Dev Tools maps to that sourceURL path instead of the "normal" path.

For example, if you work locally on a web server, then in the Sources tab in Chrome Dev Tools, the path to a given JS file will be http://localhost/Scripts/test.js

If test.js has this at the bottom

//@ sourceURL=/Scripts/test.js

then breakpoints will only work if the file path is /Scripts/test.js, not the fully-qualified URL of http://localhost/Scripts/test.js

In Chrome 38, staying with my example above, if you look at the Sources tab, every file runs off http://localhost/, so when you click on test.js, Chrome loads up http://localhost/Scripts/test.js

You can put all the breakpoints you want in this file, and Chrome never hits any of them. If you put a breakpoint in your JS before it calls any function in test.js and then step into that function, you will see that Chrome opens a new tab whose path is /Scripts/test.js. Putting breakpoints in this file will stop the program flow.

When I got rid of the @ sourceURL line from the JS file, everything works normally again (i.e. the way you would expect).

You can use the following script:

var findclasses = _doc.DocumentNode.Descendants("div").Where(d => 
    d.Attributes.Contains("class") && d.Attributes["class"].Value.Contains("float")
);

With Respect to .NET Framework 4.6 and Visual Studio 2017 you can take the below steps:

1. On the option bar at the top of visual studio, select the 4th option "Project" and under that click on the last option which says [ProjectName]Properties.Click on it & you shall see a new tab has been opened.Under that select the Application option on the left and you will see the .NET Framework version by the name "Target Framework".
2. Under Solution Explorer's tab select your project and press Alt + Enter.
3. OR simply Right-click on your project and click on the last option which says Properties.

See if the XDT (web.config) transform engine can help you. Currently it's only natively supported for web projects, but technically there is nothing stopping you from using it in other application types. There are many guides on how to use XDT by manually editing the project files, but I found a plugin that works great: https://visualstudiogallery.msdn.microsoft.com/579d3a78-3bdd-497c-bc21-aa6e6abbc859

The plugin is only helping to setup the configuration, it's not needed to build and the solution can be built on other machines or on a build server without the plugin or any other tools being required.

No, you can't use underscore in subdomain but hypen (dash). i.e my-subdomain.agahost.com is acceptable and my_subdomain.agahost.com would not be acceptable.

After some tests, here is a general object to array function convertor:

You have the object:

var obj = {
    some_key_1: "some_value_1"
    some_key_2: "some_value_2"
};

The function:

function ObjectToArray(o)
{
    var k = Object.getOwnPropertyNames(o);
    var v = Object.values(o);

    var c = function(l)
    {
        this.k = [];
        this.v = [];
        this.length = l;
    };

    var r = new c(k.length);

    for (var i = 0; i < k.length; i++)
    {
        r.k[i] = k[i];
        r.v[i] = v[i];
    }

    return r;
}

Function Use:

var arr = ObjectToArray(obj);

You Get:

arr {
    key: [
        "some_key_1",
        "some_key_2"
    ],
    value: [
        "some_value_1",
        "some_value_2"
    ],
    length: 2
}

So then you can reach all keys & values like:

for (var i = 0; i < arr.length; i++)
{
    console.log(arr.key[i] + " = " + arr.value[i]);
}

Result in console:

some_key_1 = some_value_1
some_key_2 = some_value_2

Edit:

Or in prototype form:

Object.prototype.objectToArray = function()
{
    if (
        typeof this != 'object' ||
        typeof this.length != "undefined"
    ) {
        return false;
    }

    var k = Object.getOwnPropertyNames(this);
    var v = Object.values(this);

    var c = function(l)
    {
        this.k = [];
        this.v = [];
        this.length = l;
    };

    var r = new c(k.length);

    for (var i = 0; i < k.length; i++)
    {
        r.k[i] = k[i];
        r.v[i] = v[i];
    }

    return r;
};

And then use like:

console.log(obj.objectToArray);

That ~~ is a double NOT bitwise operator.

It is used as a faster substitute for Math.floor() for positive numbers. It does not return the same result as Math.floor() for negative numbers, as it just chops off the part after the decimal (see other answers for examples of this).

you can use following helper function:

function content(divSelector, value) {
    document.querySelector(divSelector).innerHTML = value;
}

content('#content',"whatever");

Where #content must be valid CSS selector

Here is working example.

Additionaly - today (2018.07.01) I made speed comparison for jquery and pure js solutions ( MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit) ):

document.getElementById("content").innerHTML = "whatever"; // pure JS
$('#content').html('whatever');                            // jQuery

The jquery solution was slower than pure js solution: 69% on firefox, 61% on safari, 56% on chrome. The fastest browser for pure js was firefox with 560M operations per second, the second was safari 426M, and slowest was chrome 122M.

So the winners are pure js and firefox (3x faster than chrome!)

You can test it in your machine: https://jsperf.com/js-jquery-html-content-change

place a setenv.sh in the the bin directory with

JAVA_HOME=/usr/java/jdk1.6.0_43/
JRE_HOME=/usr/java/jdk1.6.0_43/jre

or an other version your running.

Question has a good pagerank on google, so for anyone who's looking for answer to this question this might be helpful.

There is an extension in google chrome marketspace to do exactly that: https://chrome.google.com/webstore/detail/hccmhjmmfdfncbfpogafcbpaebclgjcp

you can do something like this:

func HTTPPostJSON(url: String,  data: NSData,
    callback: (String, String?) -> Void) {

        var request = NSMutableURLRequest(URL: NSURL(string: url)!)
        request.HTTPMethod = "POST"
        request.addValue("application/json",forHTTPHeaderField: "Content-Type")
        request.addValue("application/json",forHTTPHeaderField: "Accept")
        request.HTTPBody = data
        HTTPsendRequest(request, callback: callback)
}

func HTTPsendRequest(request: NSMutableURLRequest,
    callback: (String, String?) -> Void) {
        let task = NSURLSession.sharedSession()
            .dataTaskWithRequest(request) {
                (data, response, error) -> Void in
                if (error != nil) {
                    callback("", error.localizedDescription)
                } else {
                    callback(NSString(data: data,
                        encoding: NSUTF8StringEncoding)! as String, nil)
                }
        }

        task.resume()
}
//use
var data :Dictionary<String, AnyObject> = yourDictionaryData<--
var requestNSData:NSData = NSJSONSerialization.dataWithJSONObject(request, options:NSJSONWritingOptions(0), error: &err)!
HTTPPostJSON("http://yourPosturl..", data: requestNSData) { (response, error) -> Void in
    if error != nil{
        //error
        return;
    }

    println(response);
}

If you mean cast a String to int, use Integer.valueOf("123").

You can't cast most other Objects to int though, because they wont have an int value. E.g. an XmlDocument has no int value.

If you want to ignore the insertion of existing value, there must be a Key field in your Table. Just create a table With Primary Key Field Like:

CREATE TABLE IF NOT EXISTS TblUsers (UserId INTEGER PRIMARY KEY, UserName varchar(100), ContactName varchar(100),Password varchar(100));

And Then Insert Or Replace / Insert Or Ignore Query on the Table Like:

INSERT OR REPLACE INTO TblUsers (UserId, UserName, ContactName ,Password) VALUES('1','UserName','ContactName','Password');

It Will Not Let it Re-Enter The Existing Primary key Value... This Is how you can Check Whether a Value exists in the table or not.

Yes, you can use bellow few functions like: First you have to convert CGPoint struct into string, see example

1) NSStringFromCGPoint,  
2) NSStringFromCGSize,  
3) NSStringFromCGRect,  
4) NSStringFromCGAffineTransform,  
5) NSStringFromUIEdgeInsets,

For example:

1) NSLog(@"NSStringFromCGPoint = %@", NSStringFromCGRect(cgPointValue));

Like this...

This is how I usually do it. A simple number of days perspective of B minus A.

DATE_PART('day', MAX(joindate) - MIN(joindate)) as date_diff

To quickly add a Javadoc use following shortcut:

Windows: alt + shift + J

Mac: ? + Alt + J

Depending on selected context, a Javadoc will be printed. To create Javadoc written by OP, select corresponding method and hit the shotcut keys.

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

Also see:

• Why declare unicode by string in python?

You could just set the width to auto. Then the width of the div will equal 0 if it has no content.

width:auto;

If you do not want to rely on the 3.5 kB plugin for jQuery or do not want to construct the HTML string while escapping reserved HTML characters, here is a simple way that works:

function addOptionToSelectBox(selectBox, optionId, optionText, selectIt)
{
    var option = document.createElement("option");
    option.value = optionId;
    option.text = optionText;
    selectBox.options[selectBox.options.length] = option;
    if (selectIt) {
        option.selected = true;
    }
}

var selectBox = $('#veryImportantSelectBox')[0];
addOptionToSelectBox(selectBox, "ID1", "Option 1", true);

    1) This problem occure due to apk file .if your apk file
        (output/apk/debug.apk) not generated in this format . 

    2) you should use always in gradle file .

    buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }

You can generate NPM dependency trees without the need of installing a dependency by using the command

npm list

This will generate a dependency tree for the project at the current directory and print it to the console.

You can get the dependency tree of a specific dependency like so:

npm list [dependency]

You can also set the maximum depth level by doing

npm list --depth=[depth]

Note that you can only view the dependency tree of a dependency that you have installed either globally, or locally to the NPM project.

If you wish to use postman the right way is to use the headers as such

key: Authorization

value: jwt {token}

as simple as that.

As others pointed out, the most straightforward way to deploy a WAR is to copy it to the webapps of the Tomcat install. Another option would be to use the manager application if it is installed (this is not always the case), if it's properly configured (i.e. if you have the credentials of a user assigned to the appropriate group) and if it you can access it over an insecure network like Internet (but this is very unlikely and you didn't mention any VPN access). So this leaves you with the webappdirectory.

Now, if Tomcat is installed and running on bilgin.ath.cx (as this is the machine where you uploaded the files), I noticed that Apache is listening to port 80 on that machien so I would bet that Tomcat is not directly exposed and that requests have to go through Apache. In that case, I think that deploying a new webapp and making it visible to the Internet will involve the edit of Apache configuration files (mod_jk?, mod_proxy?). You should either give us more details or discuss this with your hosting provider.

Update: As expected, the bilgin.ath.cx is using Apache Tomcat + Apache HTTPD + mod_jk. The configuration usually involves two files: the worker.properties file to configure the workers and the httpd.conf for Apache. Now, without seeing the current configuration, it's not easy to give a definitive answer but, basically, you may have to add a JkMount directive in Apache httpd.conf for your new webapp¹. Refer to the mod_jk documentation, it has a simple configuration example. Note that modifying httpd.conf will require access to (obviously) and proper rights and that you'll have to restart Apache after the modifications.

_{¹ I don't think you'll need to define a new worker if you are deploying to an already used Tomcat instance, especially if this sounds like Chinese for you :)}

use a polyfill like:

if(!Object.values){Object.values=obj=>Object.keys(obj).map(key=>obj[key])}

then use

Object.values(my_object)

3) profit!

I strongly suspect that's because of the network connection or the web server you're talking to - it's not BufferedReader's fault. Try measuring this:

InputStream stream = conn.getInputStream();
byte[] buffer = new byte[1000];
// Start timing
while (stream.read(buffer) > 0)
{
}
// End timing

I think you'll find it's almost exactly the same time as when you're parsing the text.

Note that you should also give InputStreamReader an appropriate encoding - the platform default encoding is almost certainly not what you should be using.

Use this package, it just works: https://github.com/jdunck/python-unicodecsv.

Well if you are using Netbeans in Linux, then you should look for the tomcat-user.xml in

/home/Username/.netbeans/8.0/apache-tomcat-8.0.3.0_base/conf

(its called Catalina Base and is often hidden) instead of the Apache installation directory.

open tomcat-user.xml inside that folder, uncomment the user and roles and add/replace the following line.

    <user username="tomcat" password="tomcat" roles="tomcat,admin,admin-gui,manager,manager-gui"/>

restart the server . That's all

You need to use array_merge_recursive instead of array_merge. Of course there can only be one key equal to 'c' in the array, but the associated value will be an array containing both 3 and 4.

Unfortunately inline elements (or elements having display:inline) ignore the width property. You should use floating divs instead:

<style type="text/css">
div.f1 { float: left; width: 20px; }
div.f2 { float: left; }
div.f3 { clear: both; }
</style>

<div class="f1"></div><div class="f2">The Lazy dog</div><div class="f3"></div>
<div class="f1">AND</div><div class="f2">The Lazy cat</div><div class="f3"></div>
<div class="f1">OR</div><div class="f2">The active goldfish</div><div class="f3"></div>

Now I see you need to use spans and lists, so we need to rewrite this a little bit:

<html><head>
<style type="text/css">
        span.f1 { display: block; float: left; clear: left; width: 60px; }
    li { list-style-type: none; }
    </style>

</head><body>
<ul>
<li><span class="f1">&nbsp;</span>The lazy dog.</li>
<li><span class="f1">AND</span> The lazy cat.</li>
<li><span class="f1">OR</span> The active goldfish.</li>
</ul>
</body>
</html>

you can accomplish your task simply by implementing as below:

private Menu menu;

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.drive_menu, menu);
    return true;
}

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    this.menu = menu;
    return super.onPrepareOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.action_toggle_grid) {
        handleMenuOption(id);
        return true;

    } else if(id == R.id.action_toggle_list){
        handleMenuOption(id);
        return true;
    }

    return super.onOptionsItemSelected(item);
}

private void handleMenuOption(int id) {
    MenuItem item = menu.findItem(id);
    if (id == R.id.action_toggle_grid){
        item.setVisible(false);
        menu.findItem(R.id.action_toggle_list).setVisible(true);
    }else if (id == R.id.action_toggle_list){
        item.setVisible(false);
        menu.findItem(R.id.action_toggle_grid).setVisible(true);
    }
}

The answer given is

def set_4(x):
   y = []
   for i in x:
       y.append(i)
   y[0] = 4
   return y

and

l = [0]

def set_3(x):
     x[0] = 3

set_3(l)
print(l[0])

which is the best answer so far as it does what it says in the question. However,it does seem a very clumsy way compared to VB or Pascal.Is it the best method we have?

Not only is it clumsy, it involves mutating the original parameter in some way manually eg by changing the original parameter to a list: or copying it to another list rather than just saying: "use this parameter as a value " or "use this one as a reference". Could the simple answer be there is no reserved word for this but these are great work arounds?

I think your document must be having enough space in the window to display its contents. That means there is no need to scroll down to see any more part of the document. In that case, document height would be equal to the window height.

I think this is a bit better :

/**
 * draws the view's content to a bitmap. code initially based on :
 * http://nadavfima.com/android-snippet-inflate-a-layout-draw-to-a-bitmap/
 */
@Nullable
public static Bitmap drawToBitmap(final View viewToDrawFrom, int width, int height) {
    boolean wasDrawingCacheEnabled = viewToDrawFrom.isDrawingCacheEnabled();
    if (!wasDrawingCacheEnabled)
        viewToDrawFrom.setDrawingCacheEnabled(true);
    if (width <= 0 || height <= 0) {
        if (viewToDrawFrom.getWidth() <= 0 || viewToDrawFrom.getHeight() <= 0) {
            viewToDrawFrom.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            width = viewToDrawFrom.getMeasuredWidth();
            height = viewToDrawFrom.getMeasuredHeight();
        }
        if (width <= 0 || height <= 0) {
            final Bitmap bmp = viewToDrawFrom.getDrawingCache();
            final Bitmap result = bmp == null ? null : Bitmap.createBitmap(bmp);
            if (!wasDrawingCacheEnabled)
                viewToDrawFrom.setDrawingCacheEnabled(false);
            return result;
        }
        viewToDrawFrom.layout(0, 0, width, height);
    } else {
        viewToDrawFrom.measure(MeasureSpec.makeMeasureSpec(width, MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY));
        viewToDrawFrom.layout(0, 0, viewToDrawFrom.getMeasuredWidth(), viewToDrawFrom.getMeasuredHeight());
    }
    final Bitmap drawingCache = viewToDrawFrom.getDrawingCache();
    final Bitmap bmp = ThumbnailUtils.extractThumbnail(drawingCache, width, height);
    final Bitmap result = bmp == null || bmp != drawingCache ? bmp : Bitmap.createBitmap(bmp);
    if (!wasDrawingCacheEnabled)
        viewToDrawFrom.setDrawingCacheEnabled(false);
    return result;
}

Using the above code, you don't have to specify the size of the bitmap (use 0 for width&height) if you want to use the one of the view itself.

Also, if you wish to convert special views (SurfaceView, Surface or Window, for example) to a bitmap, you should consider using PixelCopy class instead. It requires API 24 and above though. I don't know how to do it before.

Ways to do it:

1) KeyValuePair (Best Performance - 0.32 ns):

    KeyValuePair<int, int> Location(int p_1, int p_2, int p_3, int p_4)
    {                 
         return new KeyValuePair<int,int>(p_2 - p_1, p_4-p_3);
    }

2) Tuple - 5.40 ns:

    Tuple<int, int> Location(int p_1, int p_2, int p_3, int p_4)
    {
          return new Tuple<int, int>(p_2 - p_1, p_4-p_3);
    }

3) out (1.64 ns) or ref 4) Create your own custom class/struct

ns -> nanoseconds

Reference: multiple-return-values.

Through the this steps you can .

1. In Eclipse , Right Click on Project from Package Explorer.
2. Select Properties,.
3. Select Android from Properties pop up window,
4. See "Is Library" check box,
5. If it is checked then Unchecked "Is Library" check box.
6. Click Apply and than OK.

Scott Holden's blog entry on when to (and when not to) call GC.Collect is specific to the .NET Compact Framework, but the rules generally apply to all managed development.

In Ubuntu 20.04, I found following solution

First You need to export Android path variables. For that :

export ANDROID_SDK=~/Android/Sdk
export PATH=$ANDROID_SDK/emulator:$ANDROID_SDK/tools:$PATH

The paths may change according to your installation path. If Android Studio is installed using Ubuntu Software then path will be same as stated above.

If the export worked correctly, then following command should list your AVD names.

emulator -list-avds

In my case, I got the result

Nexus_5_API_30

Which is the name of my AVD.

If the above command have listed your AVD name, then you could run your AVD by :

emulator @YOUR_AVD_NAME

In my case

emulator @Nexus_5_API_30

You could add the export commands to .bashrc file to avoid typing export command every time you needed to run your AVD .

Use input.nextLine(); instead of input.next();

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

I think that the best choice is to organize utility things in form of groovy classes, add them to classpath and let main script refer to them via import keyword.

Example:

scripts/DbUtils.groovy

class DbUtils{
    def save(something){...}
}

scripts/script1.groovy:

import DbUtils
def dbUtils = new DbUtils()
def something = 'foobar'
dbUtils.save(something)

running script:

cd scripts
groovy -cp . script1.groovy

If you are using the default cursor, a MySQLdb.cursors.Cursor, the entire result set will be stored on the client side (i.e. in a Python list) by the time the cursor.execute() is completed.

Therefore, even if you use

for row in cursor:

you will not be getting any reduction in memory footprint. The entire result set has already been stored in a list (See self._rows in MySQLdb/cursors.py).

However, if you use an SSCursor or SSDictCursor:

import MySQLdb
import MySQLdb.cursors as cursors

conn = MySQLdb.connect(..., cursorclass=cursors.SSCursor)

then the result set is stored in the server, mysqld. Now you can write

cursor = conn.cursor()
cursor.execute('SELECT * FROM HUGETABLE')
for row in cursor:
    print(row)

and the rows will be fetched one-by-one from the server, thus not requiring Python to build a huge list of tuples first, and thus saving on memory.

Otherwise, as others have already stated, cursor.fetchall() and list(cursor) are essentially the same.

No.

localStorage is accessible by any webpage, and if you have the key, you can change whatever data you want.

That being said, if you can devise a way to safely encrypt the keys, it doesn't matter how you transfer the data, if you can contain the data within a closure, then the data is (somewhat) safe.

Xion's answer was close, but #3 (android:configChanes="orientation") won't work unless the application has an API level of 12 or lower.

In API level 13 or above, the screen size changes when the orientation changes, so this still causes the activity to be destroyed and started when orientation changes.

Simply add the "screenSize" attribute like I did below:

<activity
    android:name=".YourActivityName"
    android:configChanges="orientation|screenSize">
</activity>

Now, when you change orientation (and screen size changes), the activity keeps its state and onConfigurationChanged() is called. This will keep whatever is on the screen (ie: webpage in a Webview) when the orientation changes.

Learned this from this site: http://developer.android.com/guide/topics/manifest/activity-element.html

Also, this is apparently a bad practice so read the link below about Handling Runtime Changes:

http://developer.android.com/guide/topics/resources/runtime-changes.html

Go to Windows--> Preference--->Java--->content assist--->Enable auto activation---(insert ._@abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ in auto activation triggers for java)

Are you asking about the Server header value in the response? You can try changing that with an add_header directive, but I'm not sure if it'll work. http://wiki.codemongers.com/NginxHttpHeadersModule

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

It can be done.

From the designer: Select your DataGridView Open the Properties Navigate to ColumnHeaderDefaultCellStype Hit the button to edit the style.

You can also do it programmatically:

dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Purple;

Hope that helps!

I am not familiar with, react-table, so I do not know it has direct support for selecting and deselecting (it would be nice if it had).

If it does not, with the piece of code you already have you can install the onCLick handler. Now instead of trying to attach style directly to row, you can modify state, by for instance adding selected: true to row data. That would trigger rerender. Now you only have to override how are rows with selected === true rendered. Something along lines of:

// Any Tr element will be green if its (row.age > 20) 
<ReactTable
  getTrProps={(state, rowInfo, column) => {
    return {
      style: {
        background: rowInfo.row.selected ? 'green' : 'red'
      }
    }
  }}
/>

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

Although very late, hope it still helps someone:

Many of comments here and in other posts are concerned about setting initial size.

I used jqueryUi.Resizable. Initial widths shall be defined within each "< td >" tag at first line (< TR >). This is unlike what colResizable recommends; colResizable prohibits defining widths at first line, there I had to define widths in "< col>" tag which wasn't consikstent with jqueryresizable.

the following snippet is very neat and easier to read than usual samples:

$("#Content td").resizable({
    handles: "e, s",
    resize: function (event, ui) {
        var sizerID = "#" + $(event.target).attr("id");
        $(sizerID).width(ui.size.width);
    }
});

Content is id of my table. Handles (e, s) define in which directions the plugin can change the size. You must have a link to css of jquery-ui, otherwise it won't work.

You can retrieve the email address from the logged in user's profile. Here is the code snippet

<?php

    $facebook = new Facebook(array(
      'appId'  => $initMe["appId"],
      'secret' => $initMe["appSecret"],
    ));

    $facebook->setAccessToken($initMe["accessToken"]);
    $user = $facebook->getUser();

    if ($user) {
        $user_profile = $facebook->api('/me');
        print_r($user_profile["email"]);
    }
?>

My workaround had been using gnu sed. Worked fine for my purposes.

Here is an example that works on Chrome 5.0.375.125.

The page B (iframe content):

<html>
    <head></head>
    <body>
        <script>
            top.postMessage('hello', 'A');
        </script>
    </body>
</html>

Note the use of top.postMessage or parent.postMessage not window.postMessage here

The page A:

<html>
<head></head>
<body>
    <iframe src="B"></iframe>
    <script>
        window.addEventListener( "message",
          function (e) {
                if(e.origin !== 'B'){ return; } 
                alert(e.data);
          },
          false);
    </script>
</body>
</html>

A and B must be something like http://domain.com

EDIT:

From another question, it looks the domains(A and B here) must have a / for the postMessage to work properly.

Adding more information to Joshua Dyck's answer.

If you are using Firebase and want to use both the root route and a sub-directory route you need to add the following code in your firebase.json:

{
  "hosting": {
    "rewrites": [
      {
        "source": "*",
        "destination": "/index.html"
      },
      {
        "source": "/subdirectory/**",
        "destination": "/subdirectory/index.html"
      }
    ]
  }
}

Example:

You are building a website for a client. You want the owner of the website to add information in https://your.domain.com/management while the users of the website will navigate to https://your.domain.com.

In this case your firebase.json file will look like that:

{
  "hosting": {
    "rewrites": [
      {
        "source": "*",
        "destination": "/index.html"
      },
      {
        "source": "/management/**",
        "destination": "/management/index.html"
      }
    ]
  }
}

There are also the rows and cells members;

var t = document.getElementById("tbl");
for (var r = 0; r < t.rows.length; r++) {
    for (var c = 0; c < t.rows[r].cells.length; c++) {
        alert(t.rows[r].cells[c].innerHTML)
    }
}

It's to execute a second statement if the first statement ends succesfully. Like an if statement:

 if (1 == 1 && 2 == 2)
  echo "test;"

Its first tries if 1==1, if that is true it checks if 2==2

I do it like this:

function isString(value)
{
    return value.length !== undefined;
}
function isNumber(value)
{
    return value.NaN !== undefined;
}

Of course isString() will be tripped up here if you pass some other object that has 'length' defined.

Updating NuGet from Tools -> Extension and updates and reinstalling SQLite.Core with the command PM> Update-Package -reinstall System.Data.SQLite.Core fixed it for me.

Looking at the code below, I tried it and found: Instead of writing DBCon = DBConnection.Instance(); you should put DBConnection DBCon - new DBConnection(); (That worked for me)

and instead of MySqlComman cmd = new MySqlComman(query, DBCon.GetConnection()); you should put MySqlCommand cmd = new MySqlCommand(query, DBCon.GetConnection()); (it's missing the d)

If your intention was to find a way to represent null in an enumeration of singleton objects, then it's a bad idea to (de)reference null (it C++11, nullptr).

Why not declare static singleton object that represents NULL within the class as follows and add a cast-to-pointer operator that returns nullptr ?

Edit: Corrected several mistypes and added if-statement in main() to test for the cast-to-pointer operator actually working (which I forgot to.. my bad) - March 10 2015 -

// Error.h
class Error {
public:
  static Error& NOT_FOUND;
  static Error& UNKNOWN;
  static Error& NONE; // singleton object that represents null

public:
  static vector<shared_ptr<Error>> _instances;
  static Error& NewInstance(const string& name, bool isNull = false);

private:
  bool _isNull;
  Error(const string& name, bool isNull = false) : _name(name), _isNull(isNull) {};
  Error() {};
  Error(const Error& src) {};
  Error& operator=(const Error& src) {};

public:
  operator Error*() { return _isNull ? nullptr : this; }
};

// Error.cpp
vector<shared_ptr<Error>> Error::_instances;
Error& Error::NewInstance(const string& name, bool isNull = false)
{
  shared_ptr<Error> pNewInst(new Error(name, isNull)).
  Error::_instances.push_back(pNewInst);
  return *pNewInst.get();
}

Error& Error::NOT_FOUND = Error::NewInstance("NOT_FOUND");
//Error& Error::NOT_FOUND = Error::NewInstance("UNKNOWN"); Edit: fixed
//Error& Error::NOT_FOUND = Error::NewInstance("NONE", true); Edit: fixed
Error& Error::UNKNOWN = Error::NewInstance("UNKNOWN");
Error& Error::NONE = Error::NewInstance("NONE");

// Main.cpp
#include "Error.h"

Error& getError() {
  return Error::UNKNOWN;
}

// Edit: To see the overload of "Error*()" in Error.h actually working
Error& getErrorNone() {
  return Error::NONE;
}

int main(void) {
  if(getError() != Error::NONE) {
    return EXIT_FAILURE;
  }

  // Edit: To see the overload of "Error*()" in Error.h actually working
  if(getErrorNone() != nullptr) {
    return EXIT_FAILURE;
  }
}

Using LINQ is relatively much slower than using a predicate supplied to the Lists FindAll method. Also be careful with LINQ as the enumeration of the list is not actually executed until you access the result. This can mean that, when you think you have created a filtered list, the content may differ to what you expected when you actually read it.

You can use the IF statement in a new cell to replace text, such as:

=IF(A4="C", "Other", A4)

This will check and see if cell value A4 is "C", and if it is, it replaces it with the text "Other"; otherwise, it uses the contents of cell A4.

EDIT

Assuming that the Employee_Count values are in B1-B10, you can use this:

=IF(B1=LARGE($B$1:$B$10, 10), "Other", B1)

This function doesn't even require the data to be sorted; the LARGE function will find the 10th largest number in the series, and then the rest of the formula will compare against that.

Be careful of what you want to convert. JPG doesn't support alpha-transparency while PNG does. You will lose that information.

To convert, you may use the following function:

// Quality is a number between 0 (best compression) and 100 (best quality)
function png2jpg($originalFile, $outputFile, $quality) {
    $image = imagecreatefrompng($originalFile);
    imagejpeg($image, $outputFile, $quality);
    imagedestroy($image);
}

This function uses the imagecreatefrompng() and the imagejpeg() functions from the GD library.

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

You're already doing that, as a matter of fact. When the form is submitted, the data is passed through a post array ($_POST). Your process.php is receiving that array and redistributing its values as individual variables.
