Using the trick

Attribute VB_PredeclaredId = True

I found another more compact way:

Option Explicit
Option Base 0
Option Compare Binary

Private v_cBox As ComboBox

'
' Class creaor
Public Function New_(ByRef cBox As ComboBox) As ComboBoxExt_c
  If Me Is ComboBoxExt_c Then
    Set New_ = New ComboBoxExt_c
    Call New_.New_(cBox)
  Else
    Set v_cBox = cBox
  End If
End Function

As you can see the New_ constructor is called to both create and set the private members of the class (like init) only problem is, if called on the non-static instance it will re-initialize the private member. but that can be avoided by setting a flag.

It's really a matter of taste. Factory classes can be abstracted/interfaced away as necessary, whereas factory methods are lighter weight (and also tend to be testable, since they don't have a defined type, but they will require a well-known registration point, akin to a service locator but for locating factory methods).

this answer helped me out a lot and pointed me in the right direction but what worked for me, and hopefully others, is:

menuApp.controller("dynamicMenuController", function($scope, $http) {
$scope.appetizers= [];
$http.get('config/menu.json').success(function(data) { 
    console.log("success!");
    $scope.appetizers = data.appetizers;
        console.log(data.appetizers);
    });    
});

Many people will feel surprised maybe, but this question is incorrect. If you hear this question during an interview, you need to help the interviewer understand where the confusion is.

Let's start from the fact that there is no concrete pattern that is called just "Factory". There is pattern that is called "Abstract Factory", and there is pattern that is called "Factory Method".

So, what does "Factory" mean then? one of the following (all can be considered correct, depending on the scope of the reference):

• Some people use it as an alias (shortcut) for "Abstract Factory".
• Some people use it as an alias (shortcut) for "Factory Method".
• Some people use it as a more general name for all factory/creational patterns. E.g. both "Abstract Factory" and "Factory Method" are Factories.

And, unfortunately, many people use "Factory" to denote another kind of factory, that creates factory or factories (or their interfaces). Based on their theory:

Product implements IProduct, which is created by Factory, which implements IFactory, which is created by AbstractFactory.

To understand how silly this is, let's continue our equation:

AbstractFactory implements IAbstractFactory, which is created by... AbstractAbstractFactory???

I hope you see the point. Don't get confused, and please don't invent things that don't exist for reason.

-

P.S.: Factory for Products is AbstractFactory, and Factory for Abstract Factories would be just another example of AbstractFactory as well.

There is also a property resourceRef of JndiObjectFactoryBean that is, when set to true, used to automatically prepend the string java:comp/env/ if it is not already present.

<bean id="someId" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="jdbc/loc"/>
  <property name="resourceRef" value="true"/>
</bean>

zlib handles the deflate compression/decompression algorithm, but there is more than that in a ZIP file.

You can try libzip. It is free, portable and easy to use.

UPDATE: Here I attach quick'n'dirty example of libzip, with all the error controls ommited:

#include <zip.h>

int main()
{
    //Open the ZIP archive
    int err = 0;
    zip *z = zip_open("foo.zip", 0, &err);

    //Search for the file of given name
    const char *name = "file.txt";
    struct zip_stat st;
    zip_stat_init(&st);
    zip_stat(z, name, 0, &st);

    //Alloc memory for its uncompressed contents
    char *contents = new char[st.size];

    //Read the compressed file
    zip_file *f = zip_fopen(z, name, 0);
    zip_fread(f, contents, st.size);
    zip_fclose(f);

    //And close the archive
    zip_close(z);

    //Do something with the contents
    //delete allocated memory
    delete[] contents;
}

Use which:

 set.seed(1)
 x <- sample(10, 50, replace = TRUE)
 length(which(x > 3 & x < 5))
 # [1]  6

I had this weird error and the culprit is a white space on the beginning of the PHP open tag

even without the ob_flush and ob_end_clean

Just make sure there are no extra white spaces on or after any <?php ?> block

Assuming you already have a JFrame to call this from:

@jasonk - if you want to have "or" then negate all conditions since (A and B) <=> ~(~A or ~B)

but if you have values other than boolean try using type converters:

<MultiDataTrigger.Conditions>
    <Condition Value="True">
        <Condition.Binding>
            <MultiBinding Converter="{StaticResource conditionConverter}">
                <Binding Path="Name" />
                <Binding Path="State" />
            </MultiBinding>
        </Condition.Binding>
        <Setter Property="Background" Value="Cyan" />
    </Condition>
</MultiDataTrigger.Conditions>

you can use the values in Convert method any way you like to produce a condition which suits you.

Below works fine.

//a[@id='oldcontent']

If you've tried certain ones and they haven't worked, then let us know, otherwise something simple like this should work.

Short answer: Yes. Use Python's urllib to pull the historical data pages for the stocks you want. Go with Yahoo! Finance; Google is both less reliable, has less data coverage, and is more restrictive in how you can use it once you have it. Also, I believe Google specifically prohibits you from scraping the data in their ToS.

Longer answer: This is the script I use to pull all the historical data on a particular company. It pulls the historical data page for a particular ticker symbol, then saves it to a csv file named by that symbol. You'll have to provide your own list of ticker symbols that you want to pull.

import urllib

base_url = "http://ichart.finance.yahoo.com/table.csv?s="
def make_url(ticker_symbol):
    return base_url + ticker_symbol

output_path = "C:/path/to/output/directory"
def make_filename(ticker_symbol, directory="S&P"):
    return output_path + "/" + directory + "/" + ticker_symbol + ".csv"

def pull_historical_data(ticker_symbol, directory="S&P"):
    try:
        urllib.urlretrieve(make_url(ticker_symbol), make_filename(ticker_symbol, directory))
    except urllib.ContentTooShortError as e:
        outfile = open(make_filename(ticker_symbol, directory), "w")
        outfile.write(e.content)
        outfile.close()

Since this answer is tagged with r-faq, I felt it would be useful to share another alternative from base R: stack.

Note, however, that stack does not work with factors--it only works if is.vector is TRUE, and from the documentation for is.vector, we find that:

is.vector returns TRUE if x is a vector of the specified mode having no attributes other than names. It returns FALSE otherwise.

I'm using the sample data from @Jaap's answer, where the values in the year columns are factors.

Here's the stack approach:

cbind(wide[1:2], stack(lapply(wide[-c(1, 2)], as.character)))
##    Code     Country values  ind
## 1   AFG Afghanistan 20,249 1950
## 2   ALB     Albania  8,097 1950
## 3   AFG Afghanistan 21,352 1951
## 4   ALB     Albania  8,986 1951
## 5   AFG Afghanistan 22,532 1952
## 6   ALB     Albania 10,058 1952
## 7   AFG Afghanistan 23,557 1953
## 8   ALB     Albania 11,123 1953
## 9   AFG Afghanistan 24,555 1954
## 10  ALB     Albania 12,246 1954

I know this is an old thread but it was the first I found when searching. The += solution did not work for me. The code that I did get to work is as below.

#this bit creates the CSV if it does not already exist
$headers = "Name", "Primary Type"
$psObject = New-Object psobject
foreach($header in $headers)
{
 Add-Member -InputObject $psobject -MemberType noteproperty -Name $header -Value ""
}
$psObject | Export-Csv $csvfile -NoTypeInformation

#this bit appends a new row to the CSV file
$bName = "My Name"
$bPrimaryType = "My Primary Type"
    $hash = @{
             "Name" =  $bName
             "Primary Type" = $bPrimaryType
              }

$newRow = New-Object PsObject -Property $hash
Export-Csv $csvfile -inputobject $newrow -append -Force

I was able to use this as a function to loop through a series of arrays and enter the contents into the CSV file.

It works in powershell 3 and above.

Another way to turn off CSRF that won't render a null session is to add:

skip_before_action :verify_authenticity_token

in your Rails Controller. This will ensure you still have access to session info.

Again, make sure you only do this in API controllers or in other places where CSRF protection doesn't quite apply.

In Python, indexing starts at 0. Therefore, if you have a list with 53 items, list[52] will be the last item in the list.

short answer, specific to OAuth2,

• HS256 user client secret to generate the token signature and same secret is required to validate the token in back-end. So you should have a copy of that secret in your back-end server to verify the signature.
• RS256 use public key encryption to sign the token.Signature(hash) will create using private key and it can verify using public key. So, no need of private key or client secret to store in back-end server, but back-end server will fetch the public key from openid configuration url in your tenant (https://[tenant]/.well-known/openid-configuration) to verify the token. KID parameter inside the access_toekn will use to detect the correct key(public) from openid-configuration.

Following @jxstanford and @tvt173, I wrote a quick function which should do the trick, regardless of string/int column names:

def flatten_cols(df):
    df.columns = [
        '_'.join(tuple(map(str, t))).rstrip('_') 
        for t in df.columns.values
        ]
    return df

I used https://iconifier.net I uploaded my image, downloaded images zip file, added images to my server, followed the directions on the site including adding the links to my index.html and it worked. My favicon now shows on my iPhone in Safari when 'Add to home screen'

points or lines comes handy if

• y2 is generated later, or
• the new data does not have the same x but still should go into the same coordinate system.

As your ys share the same x, you can also use matplot:

matplot (x, cbind (y1, y2), pch = 19)

(without the pch matplopt will plot the column numbers of the y matrix instead of dots).

According to Javascript Date Documentation, you can easily do this way:

var twoHoursBefore = new Date();
twoHoursBefore.setHours(twoHoursBefore.getHours() - 2);

And don't worry about if hours you set will be out of 0..23 range. Date() object will update the date accordingly.

My advice would be this:

/garages
  Returns list of garages (think JSON array here)
/garages/yyy
  Returns specific garage
/garage/yyy/cars
  Returns list of cars in garage
/garages/cars
  Returns list of all cars in all garages (may not be practical of course)
/cars
  Returns list of all cars
/cars/xxx
  Returns specific car
/cars/colors
  Returns lists of all posible colors for cars
/cars/colors/red,blue,green
  Returns list of cars of the specific colors (yes commas are allowed :) )

Edit:

/cars/colors/red,blue,green/doors/2
  Returns list of all red,blue, and green cars with 2 doors.
/cars/type/hatchback,coupe/colors/red,blue,green/
  Same idea as the above but a lil more intuitive.
/cars/colors/red,blue,green/doors/two-door,four-door
  All cars that are red, blue, green and have either two or four doors.

Hopefully that gives you the idea. Essentially your Rest API should be easily discoverable and should enable you to browse through your data. Another advantage with using URLs and not query strings is that you are able to take advantage of the native caching mechanisms that exist on the web server for HTTP traffic.

Here's a link to a page describing the evils of query strings in REST: http://web.archive.org/web/20070815111413/http://rest.blueoxen.net/cgi-bin/wiki.pl?QueryStringsConsideredHarmful

I used Google's cache because the normal page wasn't working for me here's that link as well: http://rest.blueoxen.net/cgi-bin/wiki.pl?QueryStringsConsideredHarmful

Missing config header

Just add [mysqld] as first line in the /etc/mysql/my.cnf file.

Example

[mysqld]
default-time-zone = "+08:00"

Afterwards, remember to restart your MySQL Service.

sudo mysqld stop
sudo mysqld start

Rather than using if statements might I suggest using a switch instead, I try to avoid using if statements when possible.

var result = MessageBox.Show(@"Do you want to save the changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
switch (result)
{
    case DialogResult.Yes:
        SaveChanges();
        break;
    case DialogResult.No:
        Rollback();
        break;
    default:
        break;
}

You should not. If your private methods have enough complexity that must be tested, you should put them on another class. Keep high cohesion, a class should have only one purpose. The class public interface should be enough.

There is the Importing a repository with GitHub Importer

If you have a project hosted on another version control system as Mercurial, you can automatically import it to GitHub using the GitHub Importer tool.

1. In the upper-right corner of any page, click , and then click Import repository.
2. Under "Your old repository's clone URL", type the URL of the project you want to import.
3. Choose your user account or an organization to own the repository, then type a name for the repository on GitHub.
4. Specify whether the new repository should be public or private.
   • Public repositories are visible to any user on GitHub, so you can benefit from GitHub's collaborative community.
   • Public or private repository radio buttonsPrivate repositories are only available to the repository owner, as well as any collaborators you choose to share with.
5. Review the information you entered, then click Begin import.

You'll receive an email when the repository has been completely imported.

1. https://help.github.com/categories/importing-your-projects-to-github
2. https://help.github.com/articles/importing-a-repository-with-github-importer/

You can use Create USer to create a user

CREATE LOGIN sam
    WITH PASSWORD = '340$Uuxwp7Mcxo7Khy';
USE AdventureWorks;
CREATE USER sam FOR LOGIN sam;
GO 

and to Grant (Read-only access) you can use the following

GRANT SELECT TO sam

Hope that helps.

My fourpenneth: my SSH keys were set up in Cygwin, at C:\cygwin\home\<user>.ssh, so I pointed SSH to this folder instead of the default (Win7) C:\Users\<user>\ssh, as per these instructions: http://wiki.eclipse.org/EGit/User_Guide/Remote#Eclipse_SSH_Configuration

and used the ssh protocol, and it works fine. Trying to use the git protocol still gives "User not supported on the git protocol", though.

I was recently facing the same problem. This Error was showing on my screen after running my project main file. Error:java: invalid source release: 11 Follow the steps to resolve this error

1. File->Project Structure -> Project
2. Click New button under Project SDK: Add the latest SDK and Click OK.

After running You will see error is resolved..

As a reason of this problem, some code is broken or undefined.You may see an error in a java class such as "The type javax.servlet.http.HttpSession cannot be resolved. It is indirectly referenced from required .class files". you shuold download " javax.servlet.jar" as mentioned before. Then configure your project build path, add the javax.servlet.jar as an external jar.I hope it fixes the problem.At least it worked for me.

1) Is the synthesize within @implementation block?

2) Should you refer to self.classA = [[ClassA alloc] init]; and self.classA.downloadUrl = @"..." instead of plain classA?

3) In your myApp.m file you need to import ClassA.h, when it's missing it will default to a number, or pointer? (in C variables default to int if not found by compiler):

#import "ClassA.h".

This can be done simpler by adding two links, one with text and href and one with the dropdown and caret:

<a href="{{route('posts.index')}}">Posts</a>
<a href="{{route('posts.index')}}" class="dropdown-toggle" data-toggle="dropdown" role="link" aria-haspopup="true" aria- expanded="false"></a>
<ul class="dropdown-menu navbar-inverse bg-inverse">
    <li><a href="{{route('posts.create')}}">Create</a></li>
</ul>

Now you click the caret for dropdown and the link as a link. No css or js needed. I use Bootstrap 4 4.0.0-alpha.6, defining the caret is not necessary, it appears without the html.

in C++ expression a % b returns remainder of division of a by b (if they are positive. For negative numbers sign of result is implementation defined). For example:

5 % 2 = 1
13 % 5 = 3

With this knowledge we can try to understand your code. Condition count % 6 == 5 means that newline will be written when remainder of division count by 6 is five. How often does that happen? Exactly 6 lines apart (excercise : write numbers 1..30 and underline the ones that satisfy this condition), starting at 6-th line (count = 5).

To get desired behaviour from your code, you should change condition to count % 5 == 4, what will give you newline every 5 lines, starting at 5-th line (count = 4).

Swift 3:

let label = UILabel(frame: CGRect(x:0,y: 0,width: 250,height: 50))
label.textAlignment = .center
label.textColor = .white
label.font = UIFont(name: "Avenir-Light", size: 15.0)
label.text = "This is a Label"
self.view.addSubview(label)

to modify more css property values, you may use css object. such as:

hilight_css = {"border-bottom-color":"red", 
               "background-color":"#000"};
$(".msg").css(hilight_css);

but if the modification code is bloated. you should consider the approach March suggested. do it this way:

first, in your css file:

.hilight { border-bottom-color:red; background-color:#000; }
.msg { /* something to make it notifiable */ }

second, in your js code:

$(".msg").addClass("hilight");
// to bring message block to normal
$(".hilight").removeClass("hilight");

if ie 6 is not an issue, you can chain these classes to have more specific selectors.

The great answers have already been given, I just need to give my piece in the form of code blocks in javascript (I will also include more modern and better solution for cross-origin requests: CORS with HTTP Headers):

Yes you can.

You just need to understand what they are for, the class is more general and can be used several times, the id (is like your id's) you can use it only once.

This excellent tutorial helped me with that:

Though it's not an exact answer to your question I'm sure it will help you a lot!

Good luck!

EDIT: Reading your question, I just want to clarify that:

And that if you want to "use them" in CSS for styling purposes you should do as David Says: #x.y { }

Get all the values from MySQL:

    $post = array();
    while($row = mysql_fetch_assoc($result))
    {
        $posts[] = $row;
    }

Then, to get each value:

<?php 
     foreach ($posts as $row) 
        { 
            foreach ($row as $element)
            {
                echo $element."<br>";
            }
        }
?>

To echo the values. Or get each element from the $post variable

Adding a FileUpload control from the code behind should work just fine, where the HasFile property should be available (for instance in your Click event).

If the properties don't appear to be available (either as a compiler error or via intellisense), you probably are referencing a different variable than you think you are.

There is an odd case I got in VS2017, about the space between ‘Any’ and 'CPU'. this is not about using command prompt.

If you have a build project file, which could call other solution files. You can try to add the space between Any and CPU, like this (the Platform property value):

<MSBuild Projects="@(SolutionToBuild2)" Properties ="Configuration=$(ProjectConfiguration);Platform=Any CPU;Rerun=$(MsBuildReRun);" />

Before I fix this build issue, it is like this (ProjectPlatform is a global variable, was set to 'AnyCPU'):

<MSBuild Projects="@(SolutionToBuild1)" Properties ="Configuration=$(ProjectConfiguration);Platform=$(ProjectPlatform);Rerun=$(MsBuildReRun);" />

Also, we have a lot projects being called using $ (ProjectPlatform), which is 'AnyCPU' and work fine. If we open proj file, we can see lines liket this and it make sense.

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'">

So my conclusion is, 'AnyCPU' works for calling project files, but not for calling solution files, for calling solution files, using 'Any CPU' (add the space.)

For now, I am not sure if it is a bug of VS project file or MSBuild. I am using VS2017 with VS2017 build tools installed.

The -std=c++14 flag is not supported on GCC 4.8. If you want to use C++14 features you need to compile with -std=c++1y. Using godbolt.org it appears that the earilest version to support -std=c++14 is GCC 4.9.0 or Clang 3.5.0

Briefly bitmask helps to manipulate position of multiple values. There is a good example here ;

Bitflags are a method of storing multiple values, which are not mutually exclusive, in one variable. You've probably seen them before. Each flag is a bit position which can be set on or off. You then have a bunch of bitmasks #defined for each bit position so you can easily manipulate it:

    #define LOG_ERRORS            1  // 2^0, bit 0
    #define LOG_WARNINGS          2  // 2^1, bit 1
    #define LOG_NOTICES           4  // 2^2, bit 2
    #define LOG_INCOMING          8  // 2^3, bit 3
    #define LOG_OUTGOING         16  // 2^4, bit 4
    #define LOG_LOOPBACK         32  // and so on...

// Only 6 flags/bits used, so a char is fine
unsigned char flags;

// initialising the flags
// note that assigning a value will clobber any other flags, so you
// should generally only use the = operator when initialising vars.
flags = LOG_ERRORS;
// sets to 1 i.e. bit 0

//initialising to multiple values with OR (|)
flags = LOG_ERRORS | LOG_WARNINGS | LOG_INCOMING;
// sets to 1 + 2 + 8 i.e. bits 0, 1 and 3

// setting one flag on, leaving the rest untouched
// OR bitmask with the current value
flags |= LOG_INCOMING;

// testing for a flag
// AND with the bitmask before testing with ==
if ((flags & LOG_WARNINGS) == LOG_WARNINGS)
   ...

// testing for multiple flags
// as above, OR the bitmasks
if ((flags & (LOG_INCOMING | LOG_OUTGOING))
         == (LOG_INCOMING | LOG_OUTGOING))
   ...

// removing a flag, leaving the rest untouched
// AND with the inverse (NOT) of the bitmask
flags &= ~LOG_OUTGOING;

// toggling a flag, leaving the rest untouched
flags ^= LOG_LOOPBACK;



**

WARNING: DO NOT use the equality operator (i.e. bitflags == bitmask) for testing if a flag is set - that expression will only be true if that flag is set and all others are unset. To test for a single flag you need to use & and == :

**

if (flags == LOG_WARNINGS) //DON'T DO THIS
   ...
if ((flags & LOG_WARNINGS) == LOG_WARNINGS) // The right way
   ...
if ((flags & (LOG_INCOMING | LOG_OUTGOING)) // Test for multiple flags set
         == (LOG_INCOMING | LOG_OUTGOING))
   ...

perl -ne 'last if $. > 10; print if /pattern/' file

I believe that the dates have to be specified in the current culture of the application. You might want to experiment with setting CultureInvariantValues to true and see if that solves your problem. Otherwise you may need to change the DateTimeFormat for the current culture (or the culture itself) to get what you want.

This is add new string in the file

using (var file = new StreamWriter(filePath + "log.txt", true))
        {
            file.WriteLine(log);
            file.Close();
        }

To update the "root" Mysql user password you must have in mind that you will need of super user permissions for that. If you have super user privilegies, try the following commands:

MySQL 5.7.6 and later

sudo su
service mysql stop
mysql -u root
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
\q;
exit
mysql -u root -p MyNewPass

MySQL 5.7.5 and earlier

sudo su
service mysql stop
mysql -u root
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');
\q;
exit
mysql -u root -p MyNewPass

Wizard

Have you tried setting the height and width of the extra div, I know that on a project I am working on JS won't put anything in the div unless I have the height and width already set.

I used your code and hard coded the height and width and it shows up for me and without it doesn't show.

<body>
    <div style="height:500px; width:500px;"> <!-- ommiting the height and width will not show the map -->
         <div id="map-canvas"></div>
    </div>
</body> 

I would recommend either hard coding it in or assigning the div an ID and then add it to your CSS file.

It will already work, as David pointed out!

CSS Keyframes support is pretty good these days:

Try this:

$(document).ready(function(){
    $("#showSimpleModal").click(function() {
        $("div#simpleModal").addClass("show");
        $("#videoContainer")[0].play();
        return false;   
    });

    $("#closeSimple").click(function() {
        $("div#simpleModal").removeClass("show");
        $("#videoContainer")[0].pause();
        return false;                   
    });
});

Use a new image object each time you want to load a picture :

var image = new Image();
image.onload = function () {
    document.getElementById('id1').setAttribute('src', this.src);
};
image.src = 'http://path/to/image';

For simple iteration of key/values, sometimes libraries like underscorejs can be your friend.

const _ = require('underscore');

_.each(a, function (value, key) {
    // handle
});

See http://wiki.apache.org/httpd/DistrosDefaultLayout for discussion of where you might find Apache httpd configuration files on various platforms, since this can vary from release to release and platform to platform. The most common answer, however, is either /etc/apache/conf or /etc/httpd/conf

Generically, you can determine the answer by running the command:

httpd -V

(That's a capital V). Or, on systems where httpd is renamed, perhaps apache2ctl -V

This will return various details about how httpd is built and configured, including the default location of the main configuration file.

One of the lines of output should look like:

-D SERVER_CONFIG_FILE="conf/httpd.conf"

which, combined with the line:

-D HTTPD_ROOT="/etc/httpd"

will give you a full path to the default location of the configuration file

One way to get this error is trying to add a usercontrol to a form while the project is set to compile as x64. Visual Studio throws the unhelpful: "Failed to load toolbox item . It will be removed from the toolbox."

Workaround is to design with "Any CPU" and compile to x64 as necessary.

Using .NET 4.5 trying to perform form POST file upload. Tried most of the methods above but to no avail. Found the solution here https://www.c-sharpcorner.com/article/upload-any-file-using-http-post-multipart-form-data

But I am not not keen as I do not understand why we still need to deal with such low level programming in these common usages (should be handled nicely by framework)

In some cases (like poorly designed iterators), the class needs to keep a count or some other incidental value, that doesn't really affect the major "state" of the class. This is most often where I see mutable used. Without mutable, you'd be forced to sacrifice the entire const-ness of your design.

It feels like a hack most of the time to me as well. Useful in a very very few situations.

The below steps should be the simple fix to your problem

1. Project->Properties->ProjectFacet-->Uncheck jsf apply and OK.
2. Project->Maven->UpdateProject-->This will solve the issue.

Here while on Updating Project Maven will automatically chooses the Dynamic web module

Just send the sizeToFit message to the UITextView. It will adjust its own height to just fit its text. It will not change its own width or origin.

[textViewA1 sizeToFit];

For creating an illusion of spacing between rows, apply background color to row and then create a thick border with white color so that a "space" is created :)

tr 
{
   background-color: #FFD700;
   border: 10px solid white;
}

You may also used sed print and quit:

sed -n '10{p;q;}' file   # print line 10

I have Far.exe as the first item in the start menu.

Richtext in the clipboard ->

ctrl-escape,arrdown,enter,shift-f4,$,enter
shift-insert,ctrl-insert,alt-backspace,

-> plaintext in the clipboard

Pros: no mouse, just blind typing, ends exactly where i was before

Cons: ANSI encoding - international symbols are lost

Luckily, I do not have to do that too often :)

Like @Bergi's response, but with one difference.

Promise.all rejects all promises if one gets rejected.

So, use a recursion.

const readFilesQueue = async (files, index = 0) {
    const contents = await fs.readFile(files[index], 'utf8')
    console.log(contents)

    return files.length <= index
        ? readFilesQueue(files, ++index)
        : files

}

const printFiles async = () => {
    const files = await getFilePaths();
    const printContents = await readFilesQueue(files)

    return printContents
}

printFiles()

PS

readFilesQueue is outside of printFiles cause the side effect* introduced by console.log, it's better to mock, test, and or spy so, it's not cool to have a function that returns the content(sidenote).

Therefore, the code can simply be designed by that: three separated functions that are "pure"** and introduce no side effects, process the entire list and can easily be modified to handle failed cases.

const files = await getFilesPath()

const printFile = async (file) => {
    const content = await fs.readFile(file, 'utf8')
    console.log(content)
}

const readFiles = async = (files, index = 0) => {
    await printFile(files[index])

    return files.lengh <= index
        ? readFiles(files, ++index)
        : files
}

readFiles(files)

Future edit/current state

Node supports top-level await (this doesn't have a plugin yet, won't have and can be enabled via harmony flags), it's cool but doesn't solve one problem (strategically I work only on LTS versions). How to get the files?

Using composition. Given the code, causes to me a sensation that this is inside a module, so, should have a function to do it. If not, you should use an IIFE to wrap the role code into an async function creating simple module that's do all for you, or you can go with the right way, there is, composition.

// more complex version with IIFE to a single module
(async (files) => readFiles(await files())(getFilesPath)

Note that the name of variable changes due to semantics. You pass a functor (a function that can be invoked by another function) and recieves a pointer on memory that contains the initial block of logic of the application.

But, if's not a module and you need to export the logic?

Wrap the functions in a async function.

export const readFilesQueue = async () => {
    // ... to code goes here
}

Or change the names of variables, whatever...

* by side effect menans any colacteral effect of application that can change the statate/behaviour or introuce bugs in the application, like IO.

** by "pure", it's in apostrophe since the functions it's not pure and the code can be converged to a pure version, when there's no console output, only data manipulations.

Aside this, to be pure, you'll need to work with monads that handles the side effect, that are error prone, and treats that error separately of the application.

Use ElasticDump

1) yum install epel-release

2) yum install nodejs

3) yum install npm

4) npm install elasticdump

5) cd node_modules/elasticdump/bin

6)

./elasticdump \

  --input=http://192.168.1.1:9200/original \

  --output=http://192.168.1.2:9200/newCopy \

  --type=data

This could be a possible code for your problem :

# Note you  need to install PyAutoGUI for it to work


import pyautogui
w = pyautogui.position()
x_mouse = w.x
y_mouse = w.y
print(x_mouse, y_mouse)

A combination of the regex and SimpleDateFormat is the right answer i believe. SimpleDateFormat does not catch exception if the individual components are invalid meaning, Format Defined: yyyy-mm-dd input: 201-0-12 No exception will be thrown.This case should have been handled. But with the regex as suggested by Sok Pomaranczowy and Baby will take care of this particular case.

Change <button type="button" to <button type="submit". Remove the onClick. Instead do <form className="commentForm" onSubmit={this.onFormSubmit}>. This should catch clicking the button and pressing the return key.

onFormSubmit = e => {
  e.preventDefault();
  const { name, email } = this.state;
  // send to server with e.g. `window.fetch`
}

...

<form onSubmit={this.onFormSubmit}>
  ...
  <button type="submit">Submit</button>
</form>

For projects default:

1. Close current Project (File->Close project)

You'll get a Welcome to Android Studio Dialog. In that:

2. Click on Configure -> Project Defaults -> Project Structure

3. Click on SDK Location in the left column

4. Put the path to the Android SDK in "Android SDK location" field.

(Example SDK location: C:\android-sdk; I have sub-folders like add-ons, platforms etc under C:\android-sdk)

5. Click OK to save changes

6. Have fun!

Following steps were for older versions(<1.0) of Android Studio

4. In the middle column Click on Android SDK (with Android icon) OR click + on the top if you don't see an entry with Android icon.

5. Change SDK Home Path and select valid Target.

string dateInString = "01.10.2009";

DateTime startDate = DateTime.Parse(dateInString);
DateTime expiryDate = startDate.AddDays(30);
if (DateTime.Now > expiryDate) {
  //... trial expired
}

Creating a property with only a getter makes your property read-only for any code that is outside the class.

You can however change the value using methods provided by your class :

public class FuelConsumption {
    private double fuel;
    public double Fuel
    {
        get { return this.fuel; }
    }
    public void FillFuelTank(double amount)
    {
        this.fuel += amount;
    }
}

public static void Main()
{
    FuelConsumption f = new FuelConsumption();

    double a;
    a = f.Fuel; // Will work
    f.Fuel = a; // Does not compile

    f.FillFuelTank(10); // Value is changed from the method's code
}

Setting the private field of your class as readonly allows you to set the field value only once (using an inline assignment or in the class constructor). You will not be able to change it later.

public class ReadOnlyFields {
    private readonly double a = 2.0;
    private readonly double b;

    public ReadOnlyFields()
    {
        this.b = 4.0;
    }
}

readonly class fields are often used for variables that are initialized during class construction, and will never be changed later on.

In short, if you need to ensure your property value will never be changed from the outside, but you need to be able to change it from inside your class code, use a "Get-only" property.

If you need to store a value which will never change once its initial value has been set, use a readonly field.

Try:

float x = (float)rand()/(float)(RAND_MAX/a);

To understand how this works consider the following.

N = a random value in [0..RAND_MAX] inclusively.

The above equation (removing the casts for clarity) becomes:

N/(RAND_MAX/a)

But division by a fraction is the equivalent to multiplying by said fraction's reciprocal, so this is equivalent to:

N * (a/RAND_MAX)

which can be rewritten as:

a * (N/RAND_MAX)

Considering N/RAND_MAX is always a floating point value between 0.0 and 1.0, this will generate a value between 0.0 and a.

Alternatively, you can use the following, which effectively does the breakdown I showed above. I actually prefer this simply because it is clearer what is actually going on (to me, anyway):

float x = ((float)rand()/(float)(RAND_MAX)) * a;

Note: the floating point representation of a must be exact or this will never hit your absolute edge case of a (it will get close). See this article for the gritty details about why.

Sample

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main(int argc, char *argv[])
{
    srand((unsigned int)time(NULL));

    float a = 5.0;
    for (int i=0;i<20;i++)
        printf("%f\n", ((float)rand()/(float)(RAND_MAX)) * a);
    return 0;
}

If the properties files are externalized as environment variables following run configuration can be added into IDE:

--spring.config.additional-location={PATH_OF_EXTERNAL_PROP}

If you want to treat a null as false, then I would say that the most succinct way to do that is to use the null coalesce operator (??), as you describe:

if (nullableBool ?? false) { ... }

I have used the answer of @Dan Eastwell and it works very well. The code is similar to his code but with some additions.

.granddata {
    position: relative;
    margin-left :0.5%;
    margin-right :0.5%;
}
.granddata:after {
    content : "";
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    background-image: url("/Images/blabla.jpg");
    width: 100%;
    height: 100%;
    opacity: 0.2;
    z-index: -1;
    background-repeat: no-repeat;
    background-position: center;
    background-attachment:fixed;
}

I rename in code

++ A mistake that’s often made when approaching REST is to think of it as “web services with URLs”—to think of REST as another remote procedure call (RPC) mechanism, like SOAP, but invoked through plain HTTP URLs and without SOAP’s hefty XML namespaces.

++ On the contrary, REST has little to do with RPC. Whereas RPC is service oriented and focused on actions and verbs, REST is resource oriented, emphasizing the things and nouns that comprise an application.

BE AWARE that while changing from varchar(xxx) to varchar(yyy) is a meta-data change indeed, but changing to varchar(max) is not. Because varchar(max) values (aka BLOB values - image/text etc) are stored differently on the disk, not within a table row, but "out of row". So the server will go nuts on a big table and become unresponsive for minutes (hours).

--no downtime
ALTER TABLE MyTable ALTER COLUMN [MyColumn] VARCHAR(1200)

--huge downtime
ALTER TABLE MyTable ALTER COLUMN [MyColumn] VARCHAR(max)

PS. same applies to nvarchar or course.

Set your css in the table cell to

    <li data-pageNumber="3"> 3 </li>  
</ul

This should be enough to force an IE user to drop compatibility mode in any IE version:

<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />

However, there are a couple of caveats one should be aware of:

• The meta tag above should be included as the very first tag under <head>. Only the <title> tag may be placed above it.

If you don't do that, you'll get an error on IE9 Dev Tools: X-UA-Compatible META tag ignored because document mode is already finalized.

• If you want this markup to validate, make sure you remember to close the meta tag with a /> instead of just >.

• Starting with IE11, edge mode is the preferred document mode. To support/enable that, use the HTML5 document type declaration <!doctype html>.

• If you need to support webfonts on IE7, make sure you use <!DOCTYPE html>. I've tested it and found that rendering webfonts on IE7 got pretty unreliable when using <!doctype html>.

The use of Google Chrome Frame is popular, but unfortunately it's going to be dropped sometime this month, Jan. 2014.

<meta http-equiv="X-UA-Compatible" content="IE=EDGE,chrome=1">

You can't push into other people's repositories. This is because push permanently gets code into their repository, which is not cool.

What you should do, is to ask them to pull from your repository. This is done in GitHub by going to the other repository and sending a "pull request".

There is a very informative article on the GitHub's help itself: https://help.github.com/articles/using-pull-requests

To interact with your own repository, you have the following commands. I suggest you start reading on Git a bit more for these instructions (lots of materials online).

To add new files to the repository or add changed files to staged area:

$ git add <files>

To commit them:

$ git commit

To commit unstaged but changed files:

$ git commit -a

To push to a repository (say origin):

$ git push origin

To push only one of your branches (say master):

$ git push origin master

To fetch the contents of another repository (say origin):

$ git fetch origin

To fetch only one of the branches (say master):

$ git fetch origin master

To merge a branch with the current branch (say other_branch):

$ git merge other_branch

Note that origin/master is the name of the branch you fetched in the previous step from origin. Therefore, updating your master branch from origin is done by:

$ git fetch origin master
$ git merge origin/master

You can read about all of these commands in their manual pages (either on your linux or online), or follow the GitHub helps:

• https://help.github.com/articles/create-a-repo for commit and push
• https://help.github.com/articles/fork-a-repo for fetch and merge

If you want to call the "inner" function with the "outer" function, you can do this:

function outer() { 
     function inner() {
          alert("hi");
     }
     return { inner };
}

And on "onclick" event you call the function like this:

<input type="button" onclick="outer().inner();" value="ACTION">?

It worked for me to add a class name to the input and then apply CSS rules to that:

<input type="text" name="product" class="product" />

<style>
input[value=""].product {
    display: none;
}
</style>

Use JSON serialization and deserialization:

using Newtonsoft.Json;

Class1 obj1 = new Class1();
Class2 obj2 = JsonConvert.DeserializeObject<Class2>(JsonConvert.SerializeObject(obj1));

Or:

public class Class1
{
    public static explicit operator Class2(Class1 obj)
    {
        return JsonConvert.DeserializeObject<Class2>(JsonConvert.SerializeObject(obj));
    }
}

Which then allows you to do something like

Class1 obj1 = new Class1();
Class2 obj2 = (Class2)obj1;

seems the answer is in the comments and as an edit but to clarify this should work for you:

export BUILDDIR='your path to  build directory here'
export SRCDIR='your path to source dir here'
export BOOST_ROOT="/opt/boost/boost_1_57_0"
export BOOST_INCLUDE="/opt/boost/boost-1.57.0/include"
export BOOST_LIBDIR="/opt/boost/boost-1.57.0/lib"
export BOOST_OPTS="-DBOOST_ROOT=${BOOST_ROOT} -DBOOST_INCLUDEDIR=${BOOST_INCLUDE} -DBOOST_LIBRARYDIR=${BOOST_LIBDIR}"
(cd ${BUILDDIR} && cmake ${BOOST_OPTS} ${SRCDIR})

you need to specify the arguments as command line arguments or you can use a toolchain file for that, but cmake will not touch your environment variables.

int firstDigit = Integer.parseInt(Character.toString(firstLetterChar));

I came across the situation where I met a condition that broke the loop, however the code after the .each() function still executed. I then set a flag to "true" with an immediate check for the flag after the .each() function to ensure the code that followed was not executed.

$('.groupName').each(function() {
    if($(this).text() == groupname){
        alert('This group already exists');
        breakOut = true;
        return false;
    }
});
if(breakOut) {
    breakOut = false;
    return false;
} 

You could do this with a list comprehension

l = [x for i in range(10)];

A lot of the answers are the shortest way, not the necessarily the best way if the column has lots of nulls. Breaking the checks up allows the optimizer to evaluate the check faster as it doesn't have to do work on the other condition.

(stringexpression IS NOT NULL AND trim(stringexpression) != '')

The string comparison doesn't need to be evaluated since the first condition is false.

I feel like there should be a no javascript solution, but how is this?

http://jsfiddle.net/NfmX3/2/

$(window).resize(function() {
    $('#content').height($(window).height() - 46);
});

$(window).trigger('resize');

I think this will work (based on NonlinearFruit previous answer):

Files.walk(Paths.get("C:/test/ABC/"))
                .sorted(Comparator.reverseOrder())
                .map(Path::toFile)
                .filter(item -> !item.getPath().equals("C:/test/ABC/"))
                .forEach(File::delete);

Cheers!

Like has been mentioned already the progress field needs the keyword event

public event EventHandler<Progress> progress;

But I don't think that's where you actually want your event. I think you actually want the event in TestClass. How does the following look? (I've never actually tried setting up static events so I'm not sure if the following will compile or not, but I think this gives you an idea of the pattern you should be aiming for.)

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        TestClass.progress += SetStatus;
    }

    private void SetStatus(object sender, Progress e)
    {
        label1.Text = e.Status;
    }

    private void button1_Click_1(object sender, EventArgs e)
    {
         TestClass.Func();
    }

 }

public class TestClass
{
    public static event EventHandler<Progress> progress; 

    public static void Func()
    {
        //time consuming code
        OnProgress(new Progress("current status"));
        // time consuming code
        OnProgress(new Progress("some new status"));            
    }

    private static void OnProgress(EventArgs e) 
    {
       if (progress != null)
          progress(this, e);
    }
}


public class Progress : EventArgs
{
    public string Status { get; private set; }

    private Progress() {}

    public Progress(string status)
    {
        Status = status;
    }
}

If you have access to your apache install and trust third-party code, you can use the apache upload progress module (if you use apache; there's also a nginx upload progress module).

Otherwise, you'd have to write a script that you can hit out of band to request the status of the file (checking the filesize of the tmp file for instance).

There's some work going on in firefox 3 I believe to add upload progress support to the browser, but that's not going to get into all the browsers and be widely adopted for a while (more's the pity).

cmbEmployeeStatus.Text = "text"

If you are trying to reference a commit in another repo than the issue is in, you can prefix the commit short hash with reponame@.

Suppose your commit is in the repo named dev, and the GitLab issue is in the repo named test. You can leave a comment on the issue and reference the commit by dev@e9c11f0a (where e9c11f0a is the first 8 letters of the sha hash of the commit you want to link to) if that makes sense.

@Szkíta Had a great solution by creating a function that gets the address parts in a named array. Here is a compiled solution for those who want to use plain JavaScript.

Function to convert results to the named array:

function getAddressParts(obj) {

    var address = [];

    obj.address_components.forEach( function(el) {
        address[el.types[0]] = el.short_name;
    });

    return address;

} //getAddressParts()

Geocode the LAT/LNG values:

geocoder.geocode( { 'location' : latlng }, function(results, status) {

    if (status == google.maps.GeocoderStatus.OK) {
        var addressParts =  getAddressParts(results[0]);

        // the city
        var city = addressParts.locality;

        // the state
        var state = addressParts.administrative_area_level_1;
    }

});

The first column has a scrollbar on the cell right below the headers

<table>
    <thead>
        <th> Header 1</th>
        <th> Header 2</th>
        <th> Header 3</th>
    </thead>
    <tbody>
        <tr>
            <td>

            </td>
            <td>

            <td> Hello world2
        </tr>

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

A Pair class :

public class Pair<K, V> {

    private final K element0;
    private final V element1;

    public static <K, V> Pair<K, V> createPair(K element0, V element1) {
        return new Pair<K, V>(element0, element1);
    }

    public Pair(K element0, V element1) {
        this.element0 = element0;
        this.element1 = element1;
    }

    public K getElement0() {
        return element0;
    }

    public V getElement1() {
        return element1;
    }

}

usage :

Pair<Integer, String> pair = Pair.createPair(1, "test");
pair.getElement0();
pair.getElement1();

Immutable, only a pair !

showSoftInput was not working for me at all.

I figured I needed to set the input mode : android:windowSoftInputMode="stateVisible" (here in the Activity component in the manifest)

Hope this help!

You have to append it. Create the element with:

var $div = $("<div>my div</div>");
$div.click(function(){alert("clicked")})
return $div;

Then if you append it will work.

Take a look at your example here and a simple version here.

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

This solution worked for me

1) Click the "Export" tab for the database

2) Click the "Custom" radio button

3) Go the section titled "Format-specific options" and change the dropdown for "Database system or older MySQL server to maximize output compatibility with:" from NONE to MYSQL40.

4) Scroll to the bottom and click "GO".

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

For someone who want to use onchange event directly on file input, set onchange="somefunction(), example code from the link:

<html>
<body>
    <script language="JavaScript">
    function inform(){
        document.form1.msg.value = "Filename has been changed";
    }
    </script>
    <form name="form1">
    Please choose a file.
    <input type="file" name="uploadbox" size="35" onChange='inform()'>
    <br><br>
    Message:
    <input type="text" name="msg" size="40">
    </form>
</body>
</html>

I have an additional <category>-tag, don't know if that makes any difference.

<receiver android:name="BootIntentReceiver">  
        <intent-filter>  
            <action android:name="android.intent.action.BOOT_COMPLETED" />  
            <category android:name="android.intent.category.HOME" />  
        </intent-filter>  
</receiver>

Have you tried ommiting the if-clause "android.intent.action.BOOT_COMPLETED".equals(intent.getAction(), as the receiver probably only receives that intent anyway?

For those wanting the box-shadow on the col-* container itself and not on the .container, you can add another div just inside the col-* element, and add the shadow to that. This element will not have the padding, and therefor not interfere.

The first image has the box-shadow on the col-* element. Because of the 15px padding on the col element, the shadow is pushed to the outside of the div element rather than on the visual edges of it.

<div class="col-md-4" style="box-shadow: 0px 2px 25px rgba(0, 0, 0, .25);">
    <div class="thumbnail">
        {!! HTML::image('images/sampleImage.png') !!}
    </div>
</div>

The second image has a wrapper div with the box-shadow on it. This will place the box-shadow on the visual edges of the element.

<div class="col-md-4">
    <div id="wrapper-div" style="box-shadow: 0px 2px 25px rgba(0, 0, 0, .25);">
        <div class="thumbnail">
            {!! HTML::image('images/sampleImage.png') !!}
        </div>
    </div>
</div>

The theoretical limit (on Windows) for the maximum size of a UDP packet is 65507 bytes. This is documented here:

The correct maximum UDP message size is 65507, as determined by the following formula: 0xffff - (sizeof(IP Header) + sizeof(UDP Header)) = 65535-(20+8) = 65507

That being said, most protocols limit to a much smaller size - usually either 512 or occasionally 8192. You can often go higher than 548 safely if you are on a reliable network - but if you're broadcasting across the internet at large, the larger you go, the more likely you'll be to run into packet transmission problems and loss.

You go File->Settings->Gradle Look at the "Offline work" inbox, if it's checked u uncheck and try to sync again I have the same problem and i try this , the problem resolved. Good luck !

This is very simple to do:

import matplotlib.pyplot as plt

plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.legend(loc='best')
plt.show()

You can keep adding plt.plot as many times as you like. As for line type, you need to first specify the color. So for blue, it's b. And for a normal line it's -. An example would be:

plt.plot(total_lengths, sort_times_heap, 'b-', label="Heap")

i used replace feature in Notepad++ and replaced " (without quotes) with " and result was valid json

I know two methods:

List<int> myList1 = new List<int>(myArray);

Or,

List<int> myList2 = myArray.ToList();

I'm assuming you know about data types and will change the types as you please.

For some reason BluetoothAdapter.ACTION_ACL_CONNECTED could not be resolved by Android Studio. Perhaps it was deprecated in Android 4.2.2? Here is a modification of his code. The registration code is the same; the receiver code differs slightly. I use this in a service which updates a Bluetooth-connected flag that other parts of the app reference.

    public void onCreate() {
        //...
        IntentFilter filter = new IntentFilter();
        filter.addAction(BluetoothDevice.ACTION_ACL_CONNECTED);
        filter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED);
        filter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECTED);
        this.registerReceiver(BTReceiver, filter);
    }

    //The BroadcastReceiver that listens for bluetooth broadcasts
    private final BroadcastReceiver BTReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
            //Do something if connected
            Toast.makeText(getApplicationContext(), "BT Connected", Toast.LENGTH_SHORT).show();
        }
        else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
            //Do something if disconnected
            Toast.makeText(getApplicationContext(), "BT Disconnected", Toast.LENGTH_SHORT).show();
        }
        //else if...
    }
};

You are confusing 'sets' and 'lists'. A set does not guarantee order, but lists do.

Sets are declared using curly brackets: {}. In contrast, lists are declared using square brackets: [].

mySet = {a, b, c, c}

Does not guarantee order, but list does:

myList = [a, b, c]

For the former, convention over configuration. Rails default when you reference another table with

 belongs_to :something

is to look for something_id.

references, or belongs_to is actually newer way of writing the former with few quirks.

Important is to remember that it will not create foreign keys for you. In order to do that, you need to set it up explicitly using either:

t.references :something, foreign_key: true
t.belongs_to :something_else, foreign_key: true

or (note the plural):

add_foreign_key :table_name, :somethings
add_foreign_key :table_name, :something_elses`

One obvious advantage of artificial neural networks over support vector machines is that artificial neural networks may have any number of outputs, while support vector machines have only one. The most direct way to create an n-ary classifier with support vector machines is to create n support vector machines and train each of them one by one. On the other hand, an n-ary classifier with neural networks can be trained in one go. Additionally, the neural network will make more sense because it is one whole, whereas the support vector machines are isolated systems. This is especially useful if the outputs are inter-related.

For example, if the goal was to classify hand-written digits, ten support vector machines would do. Each support vector machine would recognize exactly one digit, and fail to recognize all others. Since each handwritten digit cannot be meant to hold more information than just its class, it makes no sense to try to solve this with an artificial neural network.

However, suppose the goal was to model a person's hormone balance (for several hormones) as a function of easily measured physiological factors such as time since last meal, heart rate, etc ... Since these factors are all inter-related, artificial neural network regression makes more sense than support vector machine regression.

If the language isn't a problem (any sandboxed scripted one) then there's LUA for .NET. The Silverlight version of the .NET framework is also sandboxed afaik.

They are both the same functionally but the .min one has all unnecessary characters removed in order to make the file size smaller.

Just to point out as well, you are better using the minified version (.min) for your live environment as Google are now checking on page loading times. Having all your JS file minified means they will load faster and will score you more brownie points.

You can get an addon for Mozilla called Page Speed that will look through your site and show you all the .JS files and provide minified versions (amongst other things).

A Trap can be identified as a transfer of control, which is initiated by the programmer. The term Trap is used interchangeably with the term Exception (which is an automatically occurring software interrupt). But some may argue that a trap is simply a special subroutine call. So they fall in to the category of software-invoked interrupts. For example, in 80×86 machines, a programmer can use the int instruction to initiate a trap. Because a trap is always unconditional the control will always be transferred to the subroutine associated with the trap. The exact instruction, which invokes the routine for handling the trap is easily identified because an explicit instruction is used to specify a trap.

It's hard to tell what you're going for in that example. exports = is about exporting from external modules, but the code sample you linked is an internal module.

Rule of thumb: If you write module foo { ... }, you're writing an internal module; if you write export something something at top-level in a file, you're writing an external module. It's somewhat rare that you'd actually write export module foo at top-level (since then you'd be double-nesting the name), and it's even rarer that you'd write module foo in a file that had a top-level export (since foo would not be externally visible).

The following things make sense (each scenario delineated by a horizontal rule):

// An internal module named SayHi with an exported function 'foo'
module SayHi {
    export function foo() {
       console.log("Hi");
    }

    export class bar { }
}

// N.B. this line could be in another file that has a
// <reference> tag to the file that has 'module SayHi' in it
SayHi.foo();
var b = new SayHi.bar();

file1.ts

// This *file* is an external module because it has a top-level 'export'
export function foo() {
    console.log('hi');
}

export class bar { }

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = module('file1');
f1.foo();
var b = new f1.bar();

file1.ts

// This will only work in 0.9.0+. This file is an external
// module because it has a top-level 'export'
function f() { }
function g() { }
export = { alpha: f, beta: g };

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = require('file1');

The value 1382086394000 is probably a time value, which is the number of milliseconds since 1970-01-01T00:00:00Z. You can use it to create an ECMAScript Date object using the Date constructor:

var d = new Date(1382086394000);

How you convert that into something readable is up to you. Simply sending it to output should call the internal (and entirely implementation dependent) toString method* that usually prints the equivalent system time in a human readable form, e.g.

Fri Oct 18 2013 18:53:14 GMT+1000 (EST) 

In ES5 there are some other built-in formatting options:

• toDateString
• toTimeString
• toLocaleString

and so on. Note that most are implementation dependent and will be different in different browsers. If you want the same format across all browsers, you'll need to format the date yourself, e.g.:

alert(d.getDate() + '/' + (d.getMonth()+1) + '/' + d.getFullYear());

* The format of Date.prototype.toString has been standardised in ECMAScript 2018. It might be a while before it's ubiquitous across all implementations, but at least the more common browsers support it now.

I found a solution on another thread that works - use the pull-left class:

 <a href="#" class="pull-left"><img src="/path/to/image.png"></a>

You can use the ZipArchive class to create a ZIP file and stream it to the client. Something like:

$files = array('readme.txt', 'test.html', 'image.gif');
$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
  $zip->addFile($file);
}
$zip->close();

and to stream it:

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);

The second line forces the browser to present a download box to the user and prompts the name filename.zip. The third line is optional but certain (mainly older) browsers have issues in certain cases without the content size being specified.

If you are working with robot framework RIDE. Then you can download Chromedriver.exe from its official website and keep this .exe file in C:\Python27\Scripts directory. Now mention this path as your environment variable eg. C:\Python27\Scripts\chromedriver.exe.

Restart your computer and run same test case again. You will not get this problem again.

If your query has any JOINs, Mysql Workbench will not allow you to alter the table, even if your results are all from a single table.

For example, the following query

SELECT u.* FROM users u JOIN passwords p ON u.id=p.user_id WHERE p.password IS NULL;

will not allow you to edit the results or add rows, even though the results are limited to one table. You must specifically do something like:

SELECT * FROM users WHERE id=1012;

and then you can edit the row and add rows to the table.

Schema in SQL Server is an object that conceptually holds definitions for other database objects such as tables,views,stored procedures etc.

The reason why Pycharm make it as a warning because Python will pass self as the first argument when calling a none static method (not add @staticmethod). Pycharm knows it.

Example:

class T:
    def test():
        print "i am a normal method!"

t = T()
t.test()
output:
Traceback (most recent call last):
  File "F:/Workspace/test_script/test.py", line 28, in <module>
    T().test()
TypeError: test() takes no arguments (1 given)

I'm from Java, in Java "self" is called "this", you don't need write self(or this) as argument in class method. You can just call self as you need inside the method. But Python "has to" pass self as a method argument.

By understanding this you don't need any Workaround as @BobStein answer.

You can only transpose a 2D array. You can use numpy.matrix to create a 2D array. This is three years late, but I am just adding to the possible set of solutions:

import numpy as np
m = np.matrix([2, 3])
m.T

You can use the RTrim function to trim all whitespace from the right. Use LTrim to trim all whitespace from the left. For example

UPDATE Table SET Name = RTrim(Name)

Or for both left and right trim

UPDATE Table SET Name = LTrim(RTrim(Name))

The second approach is right to execute JavaScript code after the page has finished loading - but you don't actually execute JavaScript code there, you inserted plain HTML.
The first thing works, but loads the JavaScript immediately and clears the page (so your tag will be there - but nothing else).
(Plus: language="javascript" has been deprecated for years, use type="text/javascript" instead!)

To get that working, you have to use the DOM manipulating methods included in JavaScript. Basically you'll need something like this:

var scriptElement=document.createElement('script');
scriptElement.type = 'text/javascript';
scriptElement.src = filename;
document.head.appendChild(scriptElement);

This article covers various ways of concatenating strings in SQL, including an improved version of your code which doesn't XML-encode the concatenated values.

SELECT ID, abc = STUFF
(
    (
        SELECT ',' + name
        FROM temp1 As T2
        -- You only want to combine rows for a single ID here:
        WHERE T2.ID = T1.ID
        ORDER BY name
        FOR XML PATH (''), TYPE
    ).value('.', 'varchar(max)')
, 1, 1, '')
FROM temp1 As T1
GROUP BY id

To understand what's happening, start with the inner query:

SELECT ',' + name
FROM temp1 As T2
WHERE T2.ID = 42 -- Pick a random ID from the table
ORDER BY name
FOR XML PATH (''), TYPE

Because you're specifying FOR XML, you'll get a single row containing an XML fragment representing all of the rows.

Because you haven't specified a column alias for the first column, each row would be wrapped in an XML element with the name specified in brackets after the FOR XML PATH. For example, if you had FOR XML PATH ('X'), you'd get an XML document that looked like:

<X>,aaa</X>
<X>,bbb</X>
...

But, since you haven't specified an element name, you just get a list of values:

,aaa,bbb,...

The .value('.', 'varchar(max)') simply retrieves the value from the resulting XML fragment, without XML-encoding any "special" characters. You now have a string that looks like:

',aaa,bbb,...'

The STUFF function then removes the leading comma, giving you a final result that looks like:

'aaa,bbb,...'

It looks quite confusing at first glance, but it does tend to perform quite well compared to some of the other options.

Building on the answer of JMax, use this formula for the dynamic named range to make the solution work for multiple rows:

=OFFSET(Sheet2!$A$1,MATCH(INDIRECT("Sheet1!"&ADDRESS(ROW(),COLUMN(),4))&"*",Sheet2!$A$1:$A$300,0)-1,0,COUNTA(Sheet2!$A:$A))

You're after the zip function.

Taken directly from the question: How to merge lists into a list of tuples in Python?

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

The at command exists specifically for this purpose (unlike cron which is intended for scheduling recurring tasks).

at $(cat file) </path/to/script

This d = t.getElementsByTagName("tr") and this r = d.getElementsByTagName("td") are both arrays. The getElementsByTagName returns an collection of elements even if there's just one found on your match.

So you have to use like this:

var t = document.getElementById("table"), // This have to be the ID of your table, not the tag
    d = t.getElementsByTagName("tr")[0],
    r = d.getElementsByTagName("td")[0];

Place the index of the array as you want to access the objects.

Note that getElementById as the name says just get the element with matched id, so your table have to be like <table id='table'> and getElementsByTagName gets by the tag.

EDIT:

Well, continuing this post, I think you can do this:

var t = document.getElementById("table");
var trs = t.getElementsByTagName("tr");
var tds = null;

for (var i=0; i<trs.length; i++)
{
    tds = trs[i].getElementsByTagName("td");
    for (var n=0; n<tds.length;n++)
    {
        tds[n].onclick=function() { alert(this.innerHTML); }
    }
}

Try it!

Sorry this answer sucks, but you can't launch an just any external application via a click, as this would be a serious security issue, this functionality isn't available in HTML or javascript. Think of just launching cmd.exe with args...you want to launch WinMerge with arguments, but you can see the security problems introduced by allowing this for anything.

The only possibly viable exception I can think of would be a protocol handler (since these are explicitly defined handlers), like winmerge://, though the best way to pass 2 file parameters I'm not sure of, if it's an option it's worth looking into, but I'm not sure what you are or are not allowed to do to the client, so this may be a non-starter solution.

Double check that you're referencing the correct type from the ServiceHost directive in the .svc file. Here's how...

1. In the VS project containing your web service, open the .svc file in the XML editor (right-click the file, Open With..., choose XML (Text) Editor, OK).
2. Note the "Service" attribute value.
3. Make sure it matches the fully qualified type name of your service. This includes the namespace + type name. For example, if the namespace is "MyCompany.Department.Services" and the class is called "MyService", then the Service attribute value should be "MyCompany.Department.Services.MyService".

Why don't you examine System.getProperty("os.arch") value in your code?

It's Unicode.

Just put the variable between str(), and it will work fine.

But in case you have two lists like the following:

a = ['co32','co36']
b = [u'co32',u'co36']

If you check set(a)==set(b), it will come as False, but if you do as follows:

b = str(b)
set(a)==set(b)

Now, the result will be True.

var index;
yourArray.some(function (elem, i) {
    return elem.prop2 === 'yutu' ? (index = i, true) : false;
});

Iterate over all elements of array. It returns either the index and true or false if the condition does not match.

Important is the explicit return value of true (or a value which boolean result is true). The single assignment is not sufficient, because of a possible index with 0 (Boolean(0) === false), which would not result an error but disables the break of the iteration.

Edit

An even shorter version of the above:

yourArray.some(function (elem, i) {
    return elem.prop2 === 'yutu' && ~(index = i);
});

Check out this one:

It's a high level library for dealing with REST. It's OOP, works with JSON, but also works with any other format.

The accepted answer builds two LocalDate objects, which are quite expensive if you are reading lot of data. I use this:

  public static int getDaysBetween(DateTime earlier, DateTime later)
  {
    return (int) TimeUnit.MILLISECONDS.toDays(later.getMillis()- earlier.getMillis());
  }

By calling getMillis() you use already existing variables.
MILLISECONDS.toDays() then, uses a simple arithmetic calculation, does not create any object.

hmm - something like this?

set host=%COMPUTERNAME%
echo %host%

EDIT: expanding on jitter's answer and using a technique in an answer to this question to set an environment variable with the result of running a command line app:

@echo off
hostname.exe > __t.tmp
set /p host=<__t.tmp
del __t.tmp
echo %host%

In either case, 'host' is created as an environment variable.

I am working with ios 7, Xcode 5. I was able to adjust the height of date picker indirectly by enclosing it in a view. The container views height can be adjusted.

You can use a UITextView and select Detection for Links, Phone Numbers and other things in the inspector.

In httpd.conf add (or change if it's already there):

AddDefaultCharset utf-8

You can use the append function to add another element to it. Only, make a series of the new element, before you append it:

test = test.append(pd.Series(200, index=[101]))

This works in python 2 and 3 and is a bit cleaner than before, but requires SA>=1.0.

Gives this output: (tested in python 2.7 and 3.4)

      '2015-06-24 18:09:29.042517', 3.14159, 100000000000000000000)
 LIMIT 1

faster to read than non cluster as data is physically storted in index order we can create only one per table.(cluster index)

quicker for insert and update operation than a cluster index. we can create n number of non cluster index.

You would use the WITH ADMIN OPTION option in the GRANT statement

For Python 3, scipy has the function scipy.special.comb, which may produce floating point as well as exact integer results

import scipy.special

res = scipy.special.comb(x, y, exact=True)

See the documentation for scipy.special.comb.

For Python 2, the function is located in scipy.misc, and it works the same way:

import scipy.misc

res = scipy.misc.comb(x, y, exact=True)

If you are more comfortable with Async task:

  new AsyncTask<Void, Void, Integer>() {
                @Override
                protected Integer doInBackground(Void... voids) {
                    return Room.databaseBuilder(getApplicationContext(),
                            AppDatabase.class, DATABASE_NAME)
                            .fallbackToDestructiveMigration()
                            .build()
                            .getRecordingDAO()
                            .getAll()
                            .size();
                }

                @Override
                protected void onPostExecute(Integer integer) {
                    super.onPostExecute(integer);
                    Toast.makeText(HomeActivity.this, "Found " + integer, Toast.LENGTH_LONG).show();
                }
            }.execute();

Its really working if we use Doctype on our web page jquery(window) will return the viewport height else it will return the complete document height.

Define the following tag on the top of your web page: <!DOCTYPE html>

All Perl's "special variables" are listed in the perlvar documentation page.

You can also use the subset function:

data <- subset(data, select=c(3,2,1))

You should better use the [] operator as in the other answers, but it may be useful to know that you can do a subset and a column reorder operation in a single command.

Update:

You can also use the select function from the dplyr package:

data = data %>% select(Time, out, In, Files)

I am not sure about the efficiency, but thanks to dplyr's syntax this solution should be more flexible, specially if you have a lot of columns. For example, the following will reorder the columns of the mtcars dataset in the opposite order:

mtcars %>% select(carb:mpg)

And the following will reorder only some columns, and discard others:

mtcars %>% select(mpg:disp, hp, wt, gear:qsec, starts_with('carb'))

Read more about dplyr's select syntax.

You can find the installed version of ur library from the properties inside references. For my case i had 8.0.0.0 installed. Error says Could not load file or assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies.

So i had to add the following manually inside web.config

  <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" />
        <bindingRedirect oldVersion="6.0.0.0-8.0.0.0" newVersion="8.0.0.0" />
      </dependentAssembly>

use this

rails d scaffold MODEL_NAME

rake db:rollback

I had a different variation on this question where I only had a single DATETIME field and needed a limit after a group by or distinct after sorting descending based on the datetime field, but this is what helped me:

select distinct (column) from
(select column from database.table
order by date_column DESC) as hist limit 10

In this instance with the split fields, if you can sort on a concat, then you might be able to get away with something like:

select name,date,time from
(select name from table order by concat(date,' ',time) ASC)
as sorted

Then if you wanted to limit you would simply add your limit statement to the end:

select name,date,time from
(select name from table order by concat(date,' ',time) ASC)
as sorted limit 10

In .NET when you pass any parameter to a method, a copy is created. In value types means that any modification you make to the value is at the method scope, and is lost when you exit the method.

When passing a Reference Type, a copy is also made, but it is a copy of a reference, i.e. now you have TWO references in memory to the same object. So, if you use the reference to modify the object, it gets modified. But if you modify the reference itself - we must remember it is a copy - then any changes are also lost upon exiting the method.

As people have said before, an assignment is a modification of the reference, thus is lost:

public void Method1(object obj) {   
 obj = new Object(); 
}

public void Method2(object obj) {  
 obj = _privateObject; 
}

The methods above does not modifies the original object.

A little modification of your example

 using System;

    class Program
        {
            static void Main(string[] args)
            {
                TestRef t = new TestRef();
                t.Something = "Foo";

                DoSomething(t);
                Console.WriteLine(t.Something);

            }

            static public void DoSomething(TestRef t)
            {
                t = new TestRef();
                t.Something = "Bar";
            }
        }



    public class TestRef
    {
    private string s;
        public string Something 
        { 
            get {return s;} 
            set { s = value; }
        }
    }

Try this configuration. It worked for me:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <warSourceDirectory>mywebRoot</warSourceDirectory>

you must have record in table or array record in database.

example:

SELECT * FROM tabel_record
WHERE table_record.fieldName IN (SELECT fieldName FROM table_reference);

I had a similar problem; after running the AdMob example, I tried to insert Ads in my app, causing this error:

01-02 16:48:51.269    8199-8199/it.dndc.BreathPlot E/AndroidRuntime? FATAL EXCEPTION: main
java.lang.IllegalStateException: Could not execute method of the activity
 Caused by: android.view.InflateException: Binary XML file line #57: Error inflating class fragment

The solution is: you cannot insert the fragment for an Ad into a ListActivity. Instead, I could add it to a FragmentActivity and to an ActionBarActivity without any problem.

My suggestion is: start from the AdMob example and add into it your existing app: I would have saved a lot of time !!!

For IIS 8 There is a extra step to do other than changing the customErrors=Off to show the error content.

<system.web>
   <customErrors mode="Off" />

<system.webServer>
   <httpErrors existingResponse="PassThrough" errorMode="Detailed"/>
</system.webServer>

I wrote this piece of code for object comparison, and it seems to work. check the assertions:

function countProps(obj) {
    var count = 0;
    for (k in obj) {
        if (obj.hasOwnProperty(k)) {
            count++;
        }
    }
    return count;
};

function objectEquals(v1, v2) {

    if (typeof(v1) !== typeof(v2)) {
        return false;
    }

    if (typeof(v1) === "function") {
        return v1.toString() === v2.toString();
    }

    if (v1 instanceof Object && v2 instanceof Object) {
        if (countProps(v1) !== countProps(v2)) {
            return false;
        }
        var r = true;

I wrote a class to normalize the data in my dictionary. The 'element' in the NormalizeData class below, needs to be of dict type. And you need to replace in the __iterate() with either your custom class object or any other object type that you would like to normalize.

class NormalizeData:

    def __init__(self, element):
        self.element = element

    def execute(self):
        if isinstance(self.element, dict):
            self.__iterate()

I had the same problem - my scenario was that I was referencing the new System.Web.Mvc.dll from a lib folder and I did not have "Copy Local" set to true. The application was then reverting back to the version in the GAC which didn't have the correct namespaces (Html, Ajax etc) in it and was giving me the run time error.

Definition:

JOINS are way to query the data that combined together from multiple tables simultaneously.

Types of JOINS:

Concern to RDBMS there are 5-types of joins:

• Equi-Join: Combines common records from two tables based on equality condition. Technically, Join made by using equality-operator (=) to compare values of Primary Key of one table and Foreign Key values of another table, hence result set includes common(matched) records from both tables. For implementation see INNER-JOIN.

• Natural-Join: It is enhanced version of Equi-Join, in which SELECT operation omits duplicate column. For implementation see INNER-JOIN

• Non-Equi-Join: It is reverse of Equi-join where joining condition is uses other than equal operator(=) e.g, !=, <=, >=, >, < or BETWEEN etc. For implementation see INNER-JOIN.

• Self-Join:: A customized behavior of join where a table combined with itself; This is typically needed for querying self-referencing tables (or Unary relationship entity). For implementation see INNER-JOINs.

• Cartesian Product: It cross combines all records of both tables without any condition. Technically, it returns the result set of a query without WHERE-Clause.

As per SQL concern and advancement, there are 3-types of joins and all RDBMS joins can be achieved using these types of joins.

1. INNER-JOIN: It merges(or combines) matched rows from two tables. The matching is done based on common columns of tables and their comparing operation. If equality based condition then: EQUI-JOIN performed, otherwise Non-EQUI-Join.

2. OUTER-JOIN: It merges(or combines) matched rows from two tables and unmatched rows with NULL values. However, can customized selection of un-matched rows e.g, selecting unmatched row from first table or second table by sub-types: LEFT OUTER JOIN and RIGHT OUTER JOIN.

   2.1. LEFT Outer JOIN (a.k.a, LEFT-JOIN): Returns matched rows from two tables and unmatched from the LEFT table(i.e, first table) only.

   2.2. RIGHT Outer JOIN (a.k.a, RIGHT-JOIN): Returns matched rows from two tables and unmatched from the RIGHT table only.

   2.3. FULL OUTER JOIN (a.k.a OUTER JOIN): Returns matched and unmatched from both tables.

3. CROSS-JOIN: This join does not merges/combines instead it performs Cartesian product.

Note: Self-JOIN can be achieved by either INNER-JOIN, OUTER-JOIN and CROSS-JOIN based on requirement but the table must join with itself.

For more information:

Examples:

1.1: INNER-JOIN: Equi-join implementation

SELECT  *
FROM Table1 A 
 INNER JOIN Table2 B ON A.<Primary-Key> =B.<Foreign-Key>;

1.2: INNER-JOIN: Natural-JOIN implementation

Select A.*, B.Col1, B.Col2          --But no B.ForeignKeyColumn in Select
 FROM Table1 A
 INNER JOIN Table2 B On A.Pk = B.Fk;

1.3: INNER-JOIN with NON-Equi-join implementation

Select *
 FROM Table1 A INNER JOIN Table2 B On A.Pk <= B.Fk;

1.4: INNER-JOIN with SELF-JOIN

Select *
 FROM Table1 A1 INNER JOIN Table1 A2 On A1.Pk = A2.Fk;

2.1: OUTER JOIN (full outer join)

Select *
 FROM Table1 A FULL OUTER JOIN Table2 B On A.Pk = B.Fk;

2.2: LEFT JOIN

Select *
 FROM Table1 A LEFT OUTER JOIN Table2 B On A.Pk = B.Fk;

2.3: RIGHT JOIN

Select *
 FROM Table1 A RIGHT OUTER JOIN Table2 B On A.Pk = B.Fk;

3.1: CROSS JOIN

Select *
 FROM TableA CROSS JOIN TableB;

3.2: CROSS JOIN-Self JOIN

Select *
 FROM Table1 A1 CROSS JOIN Table1 A2;

//OR//

Select *
 FROM Table1 A1,Table1 A2;

I have found the answer and solution to this problem. Before, I did not know that php.ini resides where in wordpress files. Now I have found that file in wp-admin directory where I placed the code

post_max_size 33M
upload_max_filesize 32M

then it worked. It increases the upload file size for my worpdress website. But, it is the same 2M as was before on cPanel.

Just add the following code:

setIconImage(new ImageIcon(PathOfFile).getImage());

Yes, it is correct. Its just a helper function to have a simpler way to access your state properties

Imagine you have a posts key in your App state.posts

state.posts //
/*    
{
  currentPostId: "",
  isFetching: false,
  allPosts: {}
}
*/

And component Posts

By default connect()(Posts) will make all state props available for the connected Component

const Posts = ({posts}) => (
  <div>
    {/* access posts.isFetching, access posts.allPosts */}
  </div> 
)

Now when you map the state.posts to your component it gets a bit nicer

const Posts = ({isFetching, allPosts}) => (
  <div>
    {/* access isFetching, allPosts directly */}
  </div> 
)

connect(
  state => state.posts
)(Posts)

mapDispatchToProps

normally you have to write dispatch(anActionCreator())

with bindActionCreators you can do it also more easily like

connect(
  state => state.posts,
  dispatch => bindActionCreators({fetchPosts, deletePost}, dispatch)
)(Posts)

Now you can use it in your Component

const Posts = ({isFetching, allPosts, fetchPosts, deletePost }) => (
  <div>
    <button onClick={() => fetchPosts()} />Fetch posts</button>
    {/* access isFetching, allPosts directly */}
  </div> 
)

Update on actionCreators..

An example of an actionCreator: deletePost

const deletePostAction = (id) => ({
  action: 'DELETE_POST',
  payload: { id },
})

So, bindActionCreators will just take your actions, wrap them into dispatch call. (I didn't read the source code of redux, but the implementation might look something like this:

const bindActionCreators = (actions, dispatch) => {
  return Object.keys(actions).reduce(actionsMap, actionNameInProps => {
    actionsMap[actionNameInProps] = (...args) => dispatch(actions[actionNameInProps].call(null, ...args))
    return actionsMap;
  }, {})
}

In your config.ini file of eclipse eclipse\configuration\config.ini check this three things:

osgi.framework=file\:plugins\\org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar
osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.0.v20080604.jar@1\:start
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator\\bundles.info

And check whether these jars are in place or not, the jar files depend upon your version of eclipse .

As trivial as it may be, I had to restart Windows when faced with this problem.

I am running Windows 7 x64. I did a manual update to the system PATH variable. This worked okay if I ran cmd.exe from the stat menu. But if I type "cmd" in the Windows Explorer address bar, it seems to load the PATH from elsewhere, which doesn't have my manual changes.

(To avoid doubt - yes, I did close and rerun cmd a couple of times before I restarted and it didn't help.)

While Guy's answer is correct (and probably fits 9 out of 10 cases), it's worth noting that if you are attempting to do this from a control that already has its DataContext set further up the stack, you'll resetting this when you set DataContext back to itself:

DataContext="{Binding RelativeSource={RelativeSource Self}}"

This will of course then break your existing bindings.

If this is the case, you should set the RelativeSource on the control you are trying to bind, rather than its parent.

i.e. for binding to a UserControl's properties:

Binding Path=PropertyName, 
        RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}

Given how difficult it can be currently to see what's going on with data binding, it's worth bearing this in mind even if you find that setting RelativeSource={RelativeSource Self} currently works :)

The built in serializer chokes with utf-8 cannot decode invalid start byte for some inputs. Instead, I went with:

def row_to_dict(row):
    temp = row.__dict__
    temp.pop('_sa_instance_state', None)
    return temp


def rows_to_list(rows):
    ret_rows = []
    for row in rows:
        ret_rows.append(row_to_dict(row))
    return ret_rows


@website_blueprint.route('/api/v1/some/endpoint', methods=['GET'])
def some_api():
    '''
    /some_endpoint
    '''
    rows = rows_to_list(SomeModel.query.all())
    response = app.response_class(
        response=jsonplus.dumps(rows),
        status=200,
        mimetype='application/json'
    )
    return response

I ran into a very similar problem with my Xamarin Windows Phone 8.1 app. The reason JObject.Parse(json) would not work for me was because my Json had a beginning "[" and an ending "]". In order to make it work, I had to remove those two characters. From your example, it looks like you might have the same issue.

jsonResult = jsonResult.TrimStart(new char[] { '[' }).TrimEnd(new char[] { ']' });

I was then able to use the JObject.Parse(jsonResult) and everything worked.

Try something like this inside ThisOutlookSession:

Private Sub Application_NewMail()
    Call Your_main_macro
End Sub

My outlook vba just fired when I received an email and had that application event open.

Edit: I just tested a hello world msg box and it ran after being called in the application_newmail event when an email was received.

Minor changes required for Kafka 0.10 and the new consumer compared to laughing_man's answer:

• Broker: No changes, you still need to increase properties message.max.bytes and replica.fetch.max.bytes. message.max.bytes has to be equal or smaller(*) than replica.fetch.max.bytes.
• Producer: Increase max.request.size to send the larger message.
• Consumer: Increase max.partition.fetch.bytes to receive larger messages.

(*) Read the comments to learn more about message.max.bytes<=replica.fetch.max.bytes

(set-face-attribute 'default nil :height 100)

The value is in 1/10pt, so 100 will give you 10pt, etc.

I know this is late but it might be of some use:

echo "<pre>";
print_r($array);
echo "</pre>";

in template

<md-button class="md-fab md-mini md-warn md-ink-ripple" ng-click="export()" aria-label="Export">
<md-icon class="material-icons" alt="Export" title="Export" aria-label="Export">
    system_update_alt
</md-icon></md-button>

in controller

     $scope.export = function(){ $window.location.href = $scope.export; };

When you include the '.' you are essentially giving the "full path" to the executable bash script, so your shell does not need to check your PATH variable. Without the '.' your shell will look in your PATH variable (which you can see by running echo $PATH to see if the command you typed lives in any of the folders on your PATH. If it doesn't (as is the case with manage.py) it says it can't find the file. It is considered bad practice to include the current directory on your PATH, which is explained reasonably well here: http://www.faqs.org/faqs/unix-faq/faq/part2/section-13.html

I've written a small library myself to accomplish this task. It uses reflection only for the first time an object type is to be translated to a datatable. It emits a method that will do all the work translating an object type.

Its blazing fast. You can find it here: ModelShredder on GoogleCode

array_walk(
    $myArray,
    function (&$entry) {
        $entry = iconv('Windows-1250', 'UTF-8', $entry);
    }
);

MY PREFERRED METHOD is using fopen,fwrite and fclose [it will cost less CPU]

$f=fopen('myfile.txt','w');
fwrite($f,'new content');
fclose($f);

Warning for those using file_put_contents

It'll affect a lot in performance, for example [on the same class/situation] file_get_contents too: if you have a BIG FILE, it'll read the whole content in one shot and that operation could take a long waiting time

The simplest and clean way to do that (actually svn 1.9, released 2015) is using:

svn info --show-item revision [--no-newline] [SVNURL/SVNPATH] 

The output is the number of the last revision (joungest) for the SVNURL, or the number of the current revision of the working copy of SVNPATH. The --no-newline is optional, instructs svn not to emit a cosmetic newline (\n) after the value, if you need minimal output (only the revision number).
