As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

If Sheets("Sheet1").OLEObjects("CheckBox1").Object.Value = True Then

I believe Tim is right. You have a Form Control. For that you have to use this

If ActiveSheet.Shapes("Check Box 1").ControlFormat.Value = 1 Then

Thing I like to do is to wrap addition columns in aggregate function, like max(). It works very good when you don't expect duplicate values.

Select MAX(cpe.createdon) As MaxDate, cpe.fmgcms_cpeclaimid, MAX(cpe.fmgcms_claimid) As fmgcms_claimid 
from Filteredfmgcms_claimpaymentestimate cpe
where cpe.createdon < 'reportstartdate'
group by cpe.fmgcms_cpeclaimid

This maybe helpful for MySql with AppArmor

stop mysql :

sudo /etc/init.d/mysql stop

Create directory called /somewhere/tmp

Edit Config:

sudo vim /etc/mysql/my.cnf # or perhaps sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

change

tmpdir = /somewhere/tmp/

Then

sudo vim /etc/apparmor.d/usr.sbin.mysqld

Add

# Allow data dir access
  /somewhere/ r,
  /somewhere/** rwk,

sudo chown -R root:root /somewhere

sudo chmod -R 1777 /somewhere

Restart

 sudo /etc/init.d/apparmor reload

 sudo /etc/init.d/mysql restart

locate the my.cnf file with the mysql config mine was under /etc/mysql/my.cnf (change the location where it says socket accordingly)

port            = 3306
socket          = /tmp/mysql.sock

Here is entries for some specific programs The following values assume you have at least 32M ram

This was formally known as [safe_mysqld]. Both versions are currently parsed.

[mysqld_safe]
socket          = /tmp/mysql.sock
nice            = 0

You might be looking for a List? Either LinkedList or ArrayList are good classes to take a look at. You can then call toArray() to get the list as an array.

Try this

Sub Sample()
    Dim test As Worksheet
    Sheets(1).Copy After:=Sheets(Sheets.Count)
    Set test = ActiveSheet
    test.Name = "copied sheet!"
End Sub

The steps I needed to perform were:

1. Add reference to System.Web.Http.WebHost.
2. Add App_Start\WebApiConfig.cs (see code snippet below).
3. Import namespace System.Web.Http in Global.asax.cs.
4. Call WebApiConfig.Register(GlobalConfiguration.Configuration) in MvcApplication.Application_Start() (in file Global.asax.cs), before registering the default Web Application route as that would otherwise take precedence.
5. Add a controller deriving from System.Web.Http.ApiController.

I could then learn enough from the tutorial (Your First ASP.NET Web API) to define my API controller.

App_Start\WebApiConfig.cs:

using System.Web.Http;

class WebApiConfig
{
    public static void Register(HttpConfiguration configuration)
    {
        configuration.Routes.MapHttpRoute("API Default", "api/{controller}/{id}",
            new { id = RouteParameter.Optional });
    }
}

Global.asax.cs:

using System.Web.Http;

...

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    RegisterGlobalFilters(GlobalFilters.Filters);
    WebApiConfig.Register(GlobalConfiguration.Configuration);
    RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

Update 10.16.2015:

Word has it, the NuGet package Microsoft.AspNet.WebApi must be installed for the above to work.

I interpreted the question as using cast on a subquery. Yes, you can do that:

select cast((<subquery>) as <newtype>)

If you do so, then you need to be sure that the returns one row and one value. And, since it returns one value, you could put the cast in the subquery instead:

select (select cast(<val> as <newtype>) . . .)

Without having to change your button group at all, you can do the following. Below, I assume your dropdown button has an id of fldCategory.

<script type="text/javascript">

$(document).ready(function(){

  $('#fldCategory').parent().find('UL LI A').click(function (e) {
    var sVal = e.currentTarget.text;
    $('#fldCategory').html(sVal + ' <span class="caret"></span>');
    console.log(sVal);
  });

});

</script>

Now, if you set the .btn-group of this item itself to have the id of fldCategory, that's actually more efficient jQuery and runs a little faster:

<script type="text/javascript">

$(document).ready(function(){

  $('#fldCategory UL LI A').click(function (e) {
    var sVal = e.currentTarget.text;
    $('#fldCategory BUTTON').html(sVal + ' <span class="caret"></span>');
    console.log(sVal);
  });

});

</script>

The only thing about using telnet to test postfix, or other SMTP, is that you have to know the commands and syntax. Instead, just use swaks :)

It's just one easy command.

If it's 7 days from now that you're looking for, just put:

$date = strtotime("+7 day", time());
echo date('M d, Y', $date);

-Ldir
Add directory dir to the list of directories to be searched for -l.

Try resetting your network settings

Settings -> General -> Reset -> Reset Network Settings

And try deleting the contents of your mac/pc lockdown folder. Here's the link, follow the steps on "Reset the Lockdown folder".

http://support.apple.com/kb/ts2529

This one worked for me.

Go to the folder in which eclipse is installed then open readme folder followed by the readme txt file. Here you will find all the info you need.

Try running below command (Works on both windows and linux)

isql -v

If you are using SQL Server 2008 or later

select convert(date, getdate())

Otherwise

select convert(varchar(10), getdate(),120)

You can use CSS hover in combination with an image background.

CSS

   .image
{
    background:url(images/back.png);
    height:100px;
    width:100px;
    display: block;
    float:left;
}

.image  a {
    display: none;
}

.image  a:hover {
    display: block;
}

HTML

<div class="image"><a href="#">Text you want on mouseover</a></div>

As Wingman said, Google App Engine is a great solution for your scenario.

You can get some information about GAE+Android here: https://developers.google.com/eclipse/docs/appengine_connected_android

And from this Google IO 2012 session: http://www.youtube.com/watch?v=NU_wNR_UUn4

"No suitable driver" usually means that the JDBC URL you've supplied to connect has incorrect syntax or when the driver isn't loaded at all.

When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from amongst those loaded at initialization and those loaded explicitly using the same classloader as the current applet or application.(using Class.forName())

For Example

import oracle.jdbc.driver.OracleDriver;

Class.forName("oracle.jdbc.driver.­OracleDriver");

Also check that you have ojdbc6.jar in your classpath. I would suggest to place .jar at physical location to JBoss "$JBOSS_HOME/server/default/lib/" directory of your project.

EDIT:

You have mentioned hibernate lately.

Check that your hibernate.cfg.xml file has connection properties something like this:

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property> 
<property name="hibernate.connection.username">scott</property>
<property name="hibernate.connection.password">tiger</property>

I had the same problem, and using this solved it.

var w = window.innerWidth;
var h = window.innerHeight;

What worked for me was to create DialogFragment an set it to not be cancelable:

dialog.setCancelable(false);

The question asks: "How can it be done in Python 3?"

Use this construct with Python 3.x:

for item in [1,2,3,4]:
    print(item, " ", end="")

This will generate:

1  2  3  4

See this Python doc for more information:

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

--

Aside:

in addition, the print() function also offers the sep parameter that lets one specify how individual items to be printed should be separated. E.g.,

In [21]: print('this','is', 'a', 'test')  # default single space between items
this is a test

In [22]: print('this','is', 'a', 'test', sep="") # no spaces between items
thisisatest

In [22]: print('this','is', 'a', 'test', sep="--*--") # user specified separation
this--*--is--*--a--*--test

If you're using Ubuntu and have "Upstart" (http://upstart.ubuntu.com/) you can try this:

Create /var/init/yourservice.conf

with the following content

description "Your Java Service"  
author "You"  

start on runlevel [3]  
stop on shutdown  

expect fork  

script     
    cd /web 
    java -jar server.jar >/var/log/yourservice.log 2>&1  
    emit yourservice_running  
end script  

Now you can issue the service yourservice start and service yourservice stop commands. You can tail /var/log/yourservice.log to verify that it's working.

If you just want to run your jar from the console without it hogging the console window, you can just do:

java -jar /web/server.jar > /var/log/yourservice.log 2>&1

If ID(and all coulmns) is needed from mytable

Using nginx/1.14.0

i have a websocket-server running on port 8097 and users connect from to wss on port 8098, nginx just decrypts the content and forwards it to the websocket server

So i have this config file (in my case /etc/nginx/conf.d/default.conf)

server {
    listen   8098;
        ssl on;
        ssl_certificate      /etc/ssl/certs/domain.crt;
        ssl_certificate_key  /root/domain.key;
    location / {

        proxy_pass http://hostname:8097;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_read_timeout 86400;

I think this will be better one.

Using subList(30, 38); will fail because max index 38 is not available in list, so its not possible.

Only way may be before asking for the sublist, you explicitly determine the max index using list size() method.

for example, check size, which returns 35, so call sublist(30, size());

OR

COPIED FROM pb2q comment

dataList = dataList.subList(30, 38 > dataList.size() ? dataList.size() : 38);

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

If your question was this -- Select ename, dname FROM emp, dept without using joins..

Then, I would do this...

SELECT ename, (SELECT dname 
FROM dept
WHERE dept.deptno=emp.deptno)dname
FROM EMP

Here is the code that will not download courpt files

$filename = "myfile.jpg";
$file = "/uploads/images/".$filename;

header('Content-type: application/octet-stream');
header("Content-Type: ".mime_content_type($file));
header("Content-Disposition: attachment; filename=".$filename);
while (ob_get_level()) {
    ob_end_clean();
}
readfile($file);

I have included mime_content_type which will return content type of file .

To prevent from corrupt file download i have added ob_get_level() and ob_end_clean();

You could skip the use of buttord, and instead just pick an order for the filter and see if it meets your filtering criterion. To generate the filter coefficients for a bandpass filter, give butter() the filter order, the cutoff frequencies Wn=[low, high] (expressed as the fraction of the Nyquist frequency, which is half the sampling frequency) and the band type btype="band".

Here's a script that defines a couple convenience functions for working with a Butterworth bandpass filter. When run as a script, it makes two plots. One shows the frequency response at several filter orders for the same sampling rate and cutoff frequencies. The other plot demonstrates the effect of the filter (with order=6) on a sample time series.

from scipy.signal import butter, lfilter


def butter_bandpass(lowcut, highcut, fs, order=5):
    nyq = 0.5 * fs
    low = lowcut / nyq
    high = highcut / nyq
    b, a = butter(order, [low, high], btype='band')
    return b, a


def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
    b, a = butter_bandpass(lowcut, highcut, fs, order=order)
    y = lfilter(b, a, data)
    return y


if __name__ == "__main__":
    import numpy as np
    import matplotlib.pyplot as plt
    from scipy.signal import freqz

    # Sample rate and desired cutoff frequencies (in Hz).
    fs = 5000.0
    lowcut = 500.0
    highcut = 1250.0

    # Plot the frequency response for a few different orders.
    plt.figure(1)
    plt.clf()
    for order in [3, 6, 9]:
        b, a = butter_bandpass(lowcut, highcut, fs, order=order)
        w, h = freqz(b, a, worN=2000)
        plt.plot((fs * 0.5 / np.pi) * w, abs(h), label="order = %d" % order)

    plt.plot([0, 0.5 * fs], [np.sqrt(0.5), np.sqrt(0.5)],
             '--', label='sqrt(0.5)')
    plt.xlabel('Frequency (Hz)')
    plt.ylabel('Gain')
    plt.grid(True)
    plt.legend(loc='best')

    # Filter a noisy signal.
    T = 0.05
    nsamples = T * fs
    t = np.linspace(0, T, nsamples, endpoint=False)
    a = 0.02
    f0 = 600.0
    x = 0.1 * np.sin(2 * np.pi * 1.2 * np.sqrt(t))
    x += 0.01 * np.cos(2 * np.pi * 312 * t + 0.1)
    x += a * np.cos(2 * np.pi * f0 * t + .11)
    x += 0.03 * np.cos(2 * np.pi * 2000 * t)
    plt.figure(2)
    plt.clf()
    plt.plot(t, x, label='Noisy signal')

    y = butter_bandpass_filter(x, lowcut, highcut, fs, order=6)
    plt.plot(t, y, label='Filtered signal (%g Hz)' % f0)
    plt.xlabel('time (seconds)')
    plt.hlines([-a, a], 0, T, linestyles='--')
    plt.grid(True)
    plt.axis('tight')
    plt.legend(loc='upper left')

    plt.show()

Here are the plots that are generated by this script:

$(function () {
    //declare function 
    $.fn.myfunction = function () {
        return true;
    };
});

$(document).ready(function () {
    //call function
    $("#my_div").myfunction();
});

from the sourcecode at http://mozilla.github.com/pdf.js/build/pdf.js

/**
 * This is the main entry point for loading a PDF and interacting with it.
 * NOTE: If a URL is used to fetch the PDF data a standard XMLHttpRequest(XHR)
 * is used, which means it must follow the same origin rules that any XHR does
 * e.g. No cross domain requests without CORS.
 *
 * @param {string|TypedAray|object} source Can be an url to where a PDF is
 * located, a typed array (Uint8Array) already populated with data or
 * and parameter object with the following possible fields:
 *  - url   - The URL of the PDF.
 *  - data  - A typed array with PDF data.
 *  - httpHeaders - Basic authentication headers.
 *  - password - For decrypting password-protected PDFs.
 *
 * @return {Promise} A promise that is resolved with {PDFDocumentProxy} object.
 */

So a standard XMLHttpRequest(XHR) is used for retrieving the document. The Problem with this is that XMLHttpRequests do not support data: uris (eg. data:application/pdf;base64,JVBERi0xLjUK...).

But there is the possibility of passing a typed Javascript Array to the function. The only thing you need to do is to convert the base64 string to a Uint8Array. You can use this function found at https://gist.github.com/1032746

var BASE64_MARKER = ';base64,';

function convertDataURIToBinary(dataURI) {
  var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
  var base64 = dataURI.substring(base64Index);
  var raw = window.atob(base64);
  var rawLength = raw.length;
  var array = new Uint8Array(new ArrayBuffer(rawLength));

  for(var i = 0; i < rawLength; i++) {

Imagine you are designing a programming language. You decide that Strings are enclosed in quotes ("Apple"). Then you hit your first snag: how to represent quotation marks since you've already used them ? Just out of convention you decide to use \" to represent quotation marks. Then you have a second problem: how to represent \ ? Again, out of convention you decide to use \\ instead. Thankfully, the process ends there and this is sufficient. You can also use what is called an escape sequence to represent other characters such as the carriage return (\n).

and(re.search("bla_bla_pattern", str_item, re.IGNORECASE) == None)

is working.

Please, try this code:

import serial
ports = serial.tools.list_ports.comports(include_links=False)
for port in ports :
    print(port.device)

first of all, you need to import package for serial port communication, so:

import serial

then you create the list of all the serial ports currently available:

ports = serial.tools.list_ports.comports(include_links=False)

and then, walking along whole list, you can for example print port names:

for port in ports :
    print(port.device)

This is just an example how to get the list of ports and print their names, but there some other options you can do with this data. Just try print different variants after

port.

I use the following script for min 8 letter password, with at least a symbol, upper and lower case letters and a number

function checkPassword(str)
{
    var re = /^(?=.*\d)(?=.*[!@#$%^&*])(?=.*[a-z])(?=.*[A-Z]).{8,}$/;
    return re.test(str);
}

If you don't want to force a declaration of a variable that is set and checked on each subtest, then adding this to a SuperTest could do:

public abstract class SuperTest {

    private static final ConcurrentHashMap<Class, Boolean> INITIALIZED = new ConcurrentHashMap<>();
    protected final boolean initialized() {
        final boolean[] absent = {false};
        INITIALIZED.computeIfAbsent(this.getClass(), (klass)-> {
            return absent[0] = true;
        });
        return !absent[0];
    }
}



public class SubTest extends SuperTest {
    @Before
    public void before() {
        if ( super.initialized() ) return;

         ... magic ... 
    }

}

With the Java 8 Date and Time API you can use the LocalDate class.

That delay you're talking about is actually a filter to prevent false (unwanted) orientation change notifications.

For instant recognition of device orientation change you're just gonna have to monitor the accelerometer yourself.

Accelerometer measures acceleration (gravity included) in all 3 axes so you shouldn't have any problems in figuring out the actual orientation.

Some code to start working with accelerometer can be found here:

How to make an iPhone App – Part 5: The Accelerometer

And this nice blog covers the math part:

Using the Accelerometer

#each

#each runs a function for each element in an array. The following two code excerpts are equivalent:

x = 10
["zero", "one", "two"].each{|element|
    x++
    puts element
}

x = 10
array = ["zero", "one", "two"]

for i in 0..2
    x++
    puts array[i]
end

#map

#map applies a function to each element of an array, returning the resulting array. The following are equivalent:

array = ["zero", "one", "two"]
newArray = array.map{|element| element.capitalize()}

array = ["zero", "one", "two"]

newArray = []
array.each{|element|
    newArray << element.capitalize()
}

#map!

#map! is like #map, but modifies the array in place. The following are equivalent:

array = ["zero", "one", "two"]
array.map!{|element| element.capitalize()}

array = ["zero", "one", "two"]
array = array.map{|element| element.capitalize()}

Nested functions and closures are now supported by many languages, including MATLAB. JavaScript promotes closures as a first class design principle.

Sadly, Octave does not support closures (nested functions with lexical scoping).

According http://osdir.com/ml/octave-bug-tracker/2013-06/msg00210.html one might even get the impression that the developers do not want or are unable to get it right.

This will break a lot of code, both ways. No workaround.

Bootstrap is just a big, useful, yet simple CSS file - not a framework or anything you can't override. I say this because I've noticed many developers got stick with BS classes and became lazy "I-can't-write-CSS-code-anymore" coders [this not being your case of course!].

If it features something you need, go with Bootstrap classes - if not, go write your additional code in good ol' style.css.

To have best of both worlds, you may write your own declarations in LESS and recompile the whole thing upon your needs, minimizing server request as a bonus.

Background images, ideally, are always done with CSS. All other images are done with html. This will span the whole background of your site.

If, like me, you had dynamically created buttons on your page, the

$("#your-bs-button's-id").on("click", function(event) {
                       or
$(".your-bs-button's-class").on("click", function(event) {

methods won't work because they only work on current elements (not future elements). Instead you need to reference a parent item that existed at the initial loading of the web page.

$(document).on("click", "#your-bs-button's-id", function(event) {
                       or more generally
$("#pre-existing-element-id").on("click", ".your-bs-button's-class", function(event) {

There are many other references to this issue on stack overflow here and here.

It's not exactly an operator, rather a keyword. And no, it doesn't do any runtime-magic.

A .jar file is akin to a .exe file. In essence, they are both executable zip files (different zip algorithms).

In a jar file, you will see folders and class files. Each class file is similar to your .o file, and is a compiled java archive.

If you wanted to see the code in a jar file, download a java decompiler (located here: http://java.decompiler.free.fr/?q=jdgui) and a .jar extractor (7zip works fine).

This is commonly caused by running out of file descriptors.

There is the systems total file descriptor limit, what do you get from the command:

sysctl fs.file-nr

This returns counts of file descriptors:

<in_use> <unused_but_allocated> <maximum>

To find out what a users file descriptor limit is run the commands:

sudo su - <username>
ulimit -Hn

To find out how many file descriptors are in use by a user run the command:

sudo lsof -u <username> 2>/dev/null | wc -l

So now if you are having a system file descriptor limit issue you will need to edit your /etc/sysctl.conf file and add, or modify it it already exists, a line with fs.file-max and set it to a value large enough to deal with the number of file descriptors you need and reboot.

fs.file-max = 204708

Within an event handler function or object method, one way to access the properties of "the containing element" is to use the special this keyword. The this keyword represents the owner of the function or method currently being processed. So:

• For a global function, this represents the window.

• For an object method, this represents the object instance.

• And in an event handler, this represents the element that received the event.

For example:

<!DOCTYPE html>
<html>
    <head>
        <script>
        function mouseDown() {
            alert(this);
        }
        </script>
    </head>
    <body>
        <p onmouseup="mouseDown();alert(this);">Hi</p>
    </body>
</html>

The content of alert windows after rendering this html respectively are:

object Window
object HTMLParagraphElement

An Event object is associated with all events. It has properties that provide information "about the event", such as the location of a mouse click in the web page.

For example:

<!DOCTYPE html>
<html>
    <head>
        <script>
        function mouseDown(event) {
            var theEvent = event ? event : window.event;
            var locString = "X = " + theEvent.screenX + " Y = " + theEvent.screenY;
            alert(event);
                    alert(locString);
        }
        </script>
    </head>
    <body>
        <p onmouseup="mouseDown(event);">Hi</p>
    </body>
</html>

The content of alert windows after rendering this html respectively are:

object MouseEvent
X = 982 Y = 329

The easisest way to get a posted json string, for example, is to read the contents of 'php://input' and then decode it. For example i had a simple Zend route:

'save-json' => array(
'type' => 'Zend\Mvc\Router\Http\Segment',
            'options' => array(
                'route'    => '/save-json/',
                'defaults' => array(
                    'controller' => 'CDB\Controller\Index',
                    'action'     => 'save-json',
                ),
            ),
        ),

and i wanted to post data to it using Angular's $http.post. The post was fine but the retrive method in Zend

$this->params()->fromPost('paramname'); 

didn't get anything in this case. So my solution was, after trying all kinds of methods like $_POST and the other methods stated above, to read from 'php://':

$content = file_get_contents('php://input');
print_r(json_decode($content));

I got my json array in the end. Hope this helps.

Sometimes you may get "Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/classworlds/Launcher" even after setting M2_HOME and PATH parameters correctly.

This exception is because your JDK/Java version need to be updated/installed.

You could use advanced options to run Google tests.

To run only some unit tests you could use --gtest_filter=Test_Cases1* command line option with value that accepts the * and ? wildcards for matching with multiple tests. I think it will solve your problem.

UPD:

Well, the question was how to run specific test cases. Integration of gtest with your GUI is another thing, which I can't really comment, because you didn't provide details of your approach. However I believe the following approach might be a good start:

1. Get all testcases by running tests with --gtest_list_tests
2. Parse this data into your GUI
3. Select test cases you want ro run
4. Run test executable with option --gtest_filter

In Excel 2007, goto Insert/Shape and pick a shape. Colour it and enter whatever text you want. Then right click on the shape and insert a hyperlink

A few tips with shapes..

If you want to easily position the shape with cells, hold down Alt when you move the shape and it will lock to the cell. If you don't want the shape to move or resize with rows/columns, right click the shape, select size and properties and choose the setting which works best.

Most of the answers fail here, when process list exceeds 20 processes. That is top -p option limit. For those with older top that does not support filtering with o options, here is a scriptable example to get full screen/console outuput (summary information is missing from this output).

__keyword="YOUR_FILTER" ; ( FILL=""; for i in  $( seq 1 $(stty size|cut -f1 -d" ")); do FILL=$'\n'$FILL; done ;  while :; do HSIZE=$(( $(stty size|cut -f1 -d" ")  - 1 ));  (top -bcn1 | grep "$__keyword"; echo "$FILL" )|head -n$HSIZE; sleep 1;done )

Some explanations

__keyword = your grep filter keyword
HSIZE=console height
FILL=new lines to fill the screen if list is shorter than console height
top -bcn1 = batch, full commandline, repeat once

The simplest solution may be to add HINTS to each find_* request.

For example:

find_library(CURL_LIBRARY
    NAMES curl curllib libcurl_imp curllib_static
    HINTS "${CMAKE_PREFIX_PATH}/curl/lib"
)

For Boost I would strongly recommend using the FindBoost standard module and setting the BOOST_DIR variable to point to your Boost libraries.

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

I done it, below code is working for me....

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.hello_world, container, false);

        Button newPage = (Button)v.findViewById(R.id.click);
        newPage.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getActivity(), HomeActivity.class);
                startActivity(intent);
            }
        });
        return v;
    }

and Please make sure that your destination activity should be register in Manifest.xml file,

but in my case all tabs are not shown in HomeActivity, is any solution for that ?

You have to be specific about the columns you are selecting. If your user table had four columns id, name, username, opted_in you must select exactly those four columns from the query. The syntax looks like:

INSERT INTO user (id, name, username, opted_in)
  SELECT id, name, username, opted_in 
  FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id

However, there does not appear to be any reason to join against user_permission here, since none of the columns from that table would be inserted into user. In fact, this INSERT seems bound to fail with primary key uniqueness violations.

MySQL does not support inserts into multiple tables at the same time. You either need to perform two INSERT statements in your code, using the last insert id from the first query, or create an AFTER INSERT trigger on the primary table.

INSERT INTO user (name, username, email, opted_in) VALUES ('a','b','c',0);
/* Gets the id of the new row and inserts into the other table */
INSERT INTO user_permission (user_id, permission_id) VALUES (LAST_INSERT_ID(), 4)

Or using a trigger:

CREATE TRIGGER creat_perms AFTER INSERT ON `user`
FOR EACH ROW
BEGIN
  INSERT INTO user_permission (user_id, permission_id) VALUES (NEW.id, 4)
END

<select id="mSelect" >
    <option value="val1" > DEF </option>
    <option value="val4" > GRT </option>
    <option value="val2" > ABC </option>
    <option value="val3" > OPL </option>
    <option value="val5" > AWS </option>
    <option value="val9" > BTY </option>
</select>

.

$("#mSelect").append($("#mSelect option").remove().sort(function(a, b) {
    var at = $(a).text(), bt = $(b).text();
    return (at > bt)?1:((at < bt)?-1:0);
}));

Let me give my 2 cents of a real-world example-analogy close to IT.

Lets say you have a subscription site, e.g a wordpress site

Each user has a role, eg admin, subscriber and so on. Many users can be admins, subscribers etc..

So abstraction here is reflected in the fact that any user with admin role can do a set of things, it does not matter which specific user this is (this is an example of abstraction).

On the other hand, subscriber users do not have access to certain settings of the site, thus some internals of the application are encapsulated for plain subscribers (this is an example of encapsulation)

As one can see abstraction and encapsulation are relative concepts, they apply with respect to something specific.

One can follow this line of reasoning and explain polymoprhism and inheritance.

For example super-admin users could do all the things admin users could do, plus some more. Moreover, if admin roles get an update in functionality, super-admins would get the same update. Thus one can see here an example of inheritance, in that super-admin roles inherit all the properties of admin roles and extend them. Note that for most part of the site, admins are interchangeable with super-admins (meaning a super-admin user can easily be used in place of an admin user, but not vice-versa in general).

Feeela is right but you can get a parent div contracting or expanding to a child element if you reverse your div positioning like this:

.parent {
    position: absolute;
    /* position it in the browser using the `left`, `top` and `margin` 
       attributes */
}

.child {
    position: relative;
    height: 100%;
    width: 100%;

    overflow: hidden;
    /* to pad or move it around using `left` and `top` inside the parent */
}

This should work for you.

Simpler and better: For API >= 16

Simply add "parentActivityName" for each activity in Manifest. The back button will automatically take u to the parent activity.

        android:name="com.example.myfirstapp.DisplayMessageActivity"

.NET 4.5 is an in place replacement for 4.0 - you will find the assemblies in the 4.0 directory.

See the blogs by Rick Strahl and Scott Hanselman on this topic.

You can also find the specific versions in:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework

You can also do the following,to import datetime

from datetime import datetime as dt

dt.strptime(date, '%Y-%m-%d')

Assuming you have referenced and correctly integrated your font to your site (presumably using an @font-face kit) it should be alright to just reference yours the way you do. Presumably it is like this so they have fall backs incase some browsers do not render the fonts correctly

First clear the temporary files in Windows system, then restart your system.

Run > %temp% > delete all files

One solution that I've found is that you should have to change the .Net Framework back to v2.0 by Right Clicking on the site that you have manager under the Application Pools from the Advance Settings.

        i                   = 0,

        changeList = function () {

            listItems.eq(i).fadeOut(transition_speed, function () {
                i += 1;
                if (i === listLen) {
                    i = 0;

If you need only an integer representing elapsed days since Jan. 1, 1970, you can try these:

// magic number=
// millisec * sec * min * hours
// 1000 * 60 * 60 * 24 = 86400000
public static final long MAGIC=86400000L;

public int DateToDays (Date date){
    //  convert a date to an integer and back again
    long currentTime=date.getTime();
    currentTime=currentTime/MAGIC;
    return (int) currentTime; 
}

public Date DaysToDate(int days) {
    //  convert integer back again to a date
    long currentTime=(long) days*MAGIC;
    return new Date(currentTime);
}

Shorter but less readable (slightly faster?):

public static final long MAGIC=86400000L;

public int DateToDays (Date date){
    return (int) (date.getTime()/MAGIC);
}

public Date DaysToDate(int days) {
    return new Date((long) days*MAGIC);
}

Hope this helps.

Keyboard accelerators are configurable. You can find out which keyboard accelerators are bound to a command in Tools -> Options on the Environment -> Keyboard page.

These commands are named Edit.CommentSelection and Edit.UncommentSelection.

(With my settings, these are bound to Ctrl+K, Ctrl+C and Ctrl+K, Ctrl+U. I would guess that these are the defaults, at least in the C++ defaults, but I don't know for sure. The best way to find out is to check your settings.)

I did a workaround by creating a new css class in my custom stylesheet as follows:

.selectwidthauto
{
     width:auto !important;
}

And then applied this class to all my select elements either manually like:

<select id="State" class="selectwidthauto">
...
</select>

Or using jQuery:

$('select').addClass('selectwidthauto');

There is a way:

<input type="number" min="0" max="100" step="5"/>

This was very helpful. Angular doesn't work exactly like JQuery. It has its own jsonp() method, which indeed requires "&callback=JSON_CALLBACK" at the end of the query string. Here's an example:

var librivoxSearch = angular.module('librivoxSearch', []);
librivoxSearch.controller('librivoxSearchController', function ($scope, $http) {
    $http.jsonp('http://librivox.org/api/feed/audiobooks/author/Melville?format=jsonp&callback=JSON_CALLBACK').success(function (data) {
        $scope.data = data;
    });
});

Then display or manipulate {{ data }} in your Angular template.

You can also directly query your DataFrame for this information.

rpt.query('STK_ID in (600809,600141,600329)')

Or similarly search for ranges:

rpt.query('60000 < STK_ID < 70000')

Using .on() you can define your function once, and it will execute for any dynamically added elements.

for example

$('#staticDiv').on('click', 'yourSelector', function() {
  //do something
});

I like to used this method the most, it will auto select the first column to the last column being used. However, if the last cell in the first row or the last cell in the first column are empty, this code will not calculate properly. Check the link for other methods to dynamically select cell range.

Sub DynamicRange()
'Best used when first column has value on last row and first row has a value in the last column

Dim sht As Worksheet
Dim LastRow As Long
Dim LastColumn As Long
Dim StartCell As Range

Set sht = Worksheets("Sheet1")
Set StartCell = Range("A1")

'Find Last Row and Column
  LastRow = sht.Cells(sht.Rows.Count, StartCell.Column).End(xlUp).Row
  LastColumn = sht.Cells(StartCell.Row, sht.Columns.Count).End(xlToLeft).Column

'Select Range
  sht.Range(StartCell, sht.Cells(LastRow, LastColumn)).Select

End Sub

<div class="col-md-9">
    <button class="btn btn-block btn-primary" type="button">Block level button</button>
</div>

In Bootstrap 3, this should be all you need. I believe btn-large was overriding the width of btn-block.

Your BlockID function uses the undefined variable images, which will lead to an error. Also, you should not use an Array here - JavaScripts key-value-maps are plain objects:

function BlockID() {
    return {
        "s": "Images/Block_01.png",
        "g": "Images/Block_02.png",
        "C": "Images/Block_03.png",
        "d": "Images/Block_04.png"
    };
}

Sure. Just put composer.phar somewhere like C:\php\composer.phar, then make a batch file somewhere within the PATH called composer.bat which does the following:

@ECHO OFF
php "%~dp0composer.phar" %*

The "%*" repeats all of the arguments passed to the shell script.

Then you can run around doing composer update all ya want!

Apache HttpClient doesn't know anything about JSON, so you'll need to construct your JSON separately. To do so, I recommend checking out the simple JSON-java library from json.org. (If "JSON-java" doesn't suit you, json.org has a big list of libraries available in different languages.)

Once you've generated your JSON, you can use something like the code below to POST it

StringRequestEntity requestEntity = new StringRequestEntity(
    JSON_STRING,
    "application/json",
    "UTF-8");

PostMethod postMethod = new PostMethod("http://example.com/action");
postMethod.setRequestEntity(requestEntity);

int statusCode = httpClient.executeMethod(postMethod);

Edit

Note - The above answer, as asked for in the question, applies to Apache HttpClient 3.1. However, to help anyone looking for an implementation against the latest Apache client:

StringEntity requestEntity = new StringEntity(
    JSON_STRING,
    ContentType.APPLICATION_JSON);

HttpPost postMethod = new HttpPost("http://example.com/action");
postMethod.setEntity(requestEntity);

HttpResponse rawResponse = httpclient.execute(postMethod);

I tweaked the previous answers by using the --sort flag and added some color/formatting:

git for-each-ref --format='%(color:cyan)%(authordate:format:%m/%d/%Y %I:%M %p)    %(align:25,left)%(color:yellow)%(authorname)%(end) %(color:reset)%(refname:strip=3)' --sort=authordate refs/remotes

A simple method will be like this:

Match match1 = Regex.Match(<input_string>, @"(?=.{7})");   

match1.Success ensures that there are at least 8 characters.

Match match2 = Regex.Match(<input_string>, [^a-zA-Z]);

match2.Success ensures that there is at least one special character or number within the string.

So, match1.Success && match2.Success guarantees will get what you want.

select column1 as xyz,
      column2 as pqr,
.....

from TableName;

Try this

var div = document.getElementById("test");
var spans = div.getElementsByTagName("span");

for(i=0;i<spans.length;i++)
{
  alert(spans[i].innerHTML);
}

WCF is a newer technology that is a viable alternative in many instances. ASP is great and works well, but I personally prefer WCF. And you can do it in .Net 4.5.

Create a new project. Right-Click on the project in solution explorer, select "Add Service Reference"

Create a textbox and button in the new application. Below is my click event for the button:

private void btnGo_Click(object sender, EventArgs e)
    {
        ServiceReference1.Service1Client testClient = new ServiceReference1.Service1Client();
        //Add error handling, null checks, etc...
        int iValue = int.Parse(txtInput.Text);
        string sResult = testClient.GetData(iValue).ToString();
        MessageBox.Show(sResult);
    }

And you're done.

This configuration worked for me in bitnami wordpress with SSL configured :

Added the below under "RewriteEngine On" in file /opt/bitnami/apps/wordpress/conf/httpd-app.conf

RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http%{ENV:protossl}://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteBase /
RewriteCond %{HTTPS} !on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

I updated Mr. ganaraj answer to show stop and resume functionality and added angular js filter to format countdown timer

it is here on jsFiddle

controller code

'use strict';
var myApp = angular.module('myApp', []);
myApp.controller('AlbumCtrl', function($scope,$timeout) {
    $scope.counter = 0;
    $scope.stopped = false;
    $scope.buttonText='Stop';
    $scope.onTimeout = function(){
        $scope.counter++;
        mytimeout = $timeout($scope.onTimeout,1000);
    }
    var mytimeout = $timeout($scope.onTimeout,1000);
    $scope.takeAction = function(){
        if(!$scope.stopped){
            $timeout.cancel(mytimeout);
            $scope.buttonText='Resume';
        }
        else
        {
            mytimeout = $timeout($scope.onTimeout,1000);
            $scope.buttonText='Stop';
        }
            $scope.stopped=!$scope.stopped;
    }   
});

filter-code adapted from RobG from stackoverflow

myApp.filter('formatTimer', function() {
  return function(input)
    {
        function z(n) {return (n<10? '0' : '') + n;}
        var seconds = input % 60;
        var minutes = Math.floor(input / 60);
        var hours = Math.floor(minutes / 60);
        return (z(hours) +':'+z(minutes)+':'+z(seconds));
    };
});

You can also try this, suppose if you want to make a back image button and you have "500x500 png" and want it to fit in small button size.

Use dp to fix ImageView's size.

add this line of code to your Imageview.

android:scaleType="fitXY"

EXAMPLE:

<ImageView
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:id="@+id/imageView2"
        android:src="@drawable/Backicon"
        android:scaleType="fitXY"
        />

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

SELECT COUNT(ID) FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For count


SELECT ID FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For results

If you have integers in your file fscanf returns 1 until integer occurs. For example:

FILE *in = fopen("./task.in", "r");
int length = 0;
int counter;
int sequence;

for ( int i = 0; i < 10; i++ ) {
    counter = fscanf(in, "%d", &sequence);
    if ( counter == 1 ) {
        length += 1;
    }
}

To find out the end of the file with symbols you can use EOF. For example:

char symbol;
FILE *in = fopen("./task.in", "r");

for ( ; fscanf(in, "%c", &symbol) != EOF; ) {
    printf("%c", symbol); 
}
