I have found this way of reading strings from files to work best for me

String st, full;
full="";
BufferedReader br = new BufferedReader(new FileReader(URL));
while ((st=br.readLine())!=null) {
    full+=st;
}

"full" will be the completed combination of all of the lines. If you want to add a line break between the lines of text you would do full+=st+"\n";

With JQuery you can try this $(window).innerHeight() (Works for me on Chrome, FF and IE). With bootstrap modal I used something like the following;

$('#YourModal').on('show.bs.modal', function () {
    $('.modal-body').css('height', $(window).innerHeight() * 0.7);
});

If you set the margin to be margin:0 auto the image will be centered.

This will give top + bottom a margin of 0, and left and right a margin of 'auto'. Since the div has a width (200px), the image will be 200px wide and the browser will auto set the left and right margin to half of what is left on the page, which will result in the image being centered.

This is technically a language-dependent, but almost all languages treat this subject the same. When there is a type mismatch between two data types in an expression, most languages will try to cast the data on one side of the = to match the data on the other side according to a set of predefined rules.

When dividing two numbers of the same type (integers, doubles, etc.) the result will always be of the same type (so 'int/int' will always result in int).

In this case you have double var = integer result which casts the integer result to a double after the calculation in which case the fractional data is already lost. (most languages will do this casting to prevent type inaccuracies without raising an exception or error).

If you'd like to keep the result as a double you're going to want to create a situation where you have double var = double result

The easiest way to do that is to force the expression on the right side of an equation to cast to double:

c = a/(double)b

Division between an integer and a double will result in casting the integer to the double (note that when doing maths, the compiler will often "upcast" to the most specific data type this is to prevent data loss).

After the upcast, a will wind up as a double and now you have division between two doubles. This will create the desired division and assignment.

AGAIN, please note that this is language specific (and can even be compiler specific), however almost all languages (certainly all the ones I can think of off the top of my head) treat this example identically.

UPDATE `table` SET table_column='test';

Best use of application class. Example: Suppose you need to restart your alarm manager on boot completed.

public class BaseJuiceApplication extends Application implements BootListener {

    public static BaseJuiceApplication instance = null;

    public static Context getInstance() {
        if (null == instance) {
            instance = new BaseJuiceApplication();
        }
        return instance;
    }

    @Override
    public void onCreate() {
        super.onCreate();


    }

    @Override
    public void onBootCompleted(Context context, Intent intent) {
        new PushService().scheduleService(getInstance());
        //startToNotify(context);
    }

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder

Sample Code

File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
        if(!imageFile.exists()){//file doesnot exist in SDCard

        imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
        }

Edit: Harhar is now open source. I have updated the URL below.

If you use an Avalanche load generator, you can use Harhar to replay a HAR file at very high load: https://acastaner.github.io/harhar/

This tool handles the "content" you use when you "Save as HAR with content."

Gosh, NO!!! You're asking for a world of hurt if you store formatted dates in SQL Server. Always store your dates and times and one of the SQL Server "date/time" datatypes (DATETIME, DATE, TIME, DATETIME2, whatever). Let the front end code resolve the method of display and only store formatted dates when you're building a staging table to build a file from. If you absolutely must display ISO date/time formats from SQL Server, only do it at display time. I can't emphasize enough... do NOT store formatted dates/times in SQL Server.

{Edit}. The reasons for this are many but the most obvious are that, even with a nice ISO format (which is sortable), all future date calculations and searches (search for all rows in a given month, for example) will require at least an implicit conversion (which takes extra time) and if the stored formatted date isn't the format that you currently need, you'll need to first convert it to a date and then to the format you want.

The same holds true for front end code. If you store a formatted date (which is text), it requires the same gyrations to display the local date format defined either by windows or the app.

My recommendation is to always store the date/time as a DATETIME or other temporal datatype and only format the date at display time.

In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.

This is helpful when your equals method call throws some exception e.g. NullPointerException;

     boolean isMatch = false;

     try{
         isMatch = email1.equals (email2);
      }catch(NullPointerException npe){
         .....
      }
      System.out.print("Match=="+isMatch);
      if(isMatch){
        ......
      }

For enum type, I think this is a suitable way, and the difference between class is how to calculate hash value.

template <typename T>
struct EnumTypeHash {
  std::size_t operator()(const T& type) const {
    return static_cast<std::size_t>(type);
  }
};

enum MyEnum {};
class MyValue {};

std::unordered_map<MyEnum, MyValue, EnumTypeHash<MyEnum>> map_;

Its very simple though conditions in this answer are in mysql the column datatype is datetime and you want to send data from java code to mysql:

java.util.Date dt = new java.util.Date();
whatever your code object may be.setDateTime(dt);

important thing is just pick the date and its format is already as per mysql format and send it, no further modifications required.

We have a weekly sql dump into a subversion repo. It's fully automated but it's a REALLY beefy task.

You'll want to limit the number of revisions because it really chows disk space after a while!

My method. One gesture recognizer to rule them all:

class DisabledGestureViewController: UIViewController: UIGestureRecognizerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        navigationController!.interactivePopGestureRecognizer!.delegate = self
    }

    func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool {
        // Prevent going back to the previous view
        return !(navigationController!.topViewController is DisabledGestureViewController)
    }
}

Important: don't reset the delegate anywhere in the navigation stack: navigationController!.interactivePopGestureRecognizer!.delegate = nil

If your Web Host is through C Panel Enable G ZIP Compression on Apache C Panel

Go to CPanel and check for software tab.

Previously Optimize website used to work but now a new option is available i.e "MultiPHP INI Editor".

Select the domain name you want to compress.

Scroll down to bottom until you find zip output compression and enable it.

Now check again for the G ZIP Compression.

You can follow the video tutorial also. https://www.youtube.com/watch?v=o0UDmcpGlZI

Just a thought, but Have you tried using application.undo

This will set the values back again. You can then simply read the original value. It should not be too difficult to store the new values first, so you change them back again if you like.

I often do binary rpm per packaging proprietary apps - also moster as websphere - on linux. So my experience could be useful also a you, besides that it would better to do a TRUE RPM if you can. But i digress.

So the a basic step for packaging your (binary) program is as follow - in which i suppose the program is toybinprog with version 1.0, have a conf to be installed in /etc/toybinprog/toybinprog.conf and have a bin to be installed in /usr/bin called tobinprog :

1. create your rpm build env for RPM < 4.6,4.7

mkdir -p ~/rpmbuild/{RPMS,SRPMS,BUILD,SOURCES,SPECS,tmp}

cat <<EOF >~/.rpmmacros
%_topdir   %(echo $HOME)/rpmbuild
%_tmppath  %{_topdir}/tmp
EOF

cd ~/rpmbuild

2. create the tarball of your project

mkdir toybinprog-1.0
mkdir -p toybinprog-1.0/usr/bin
mkdir -p toybinprog-1.0/etc/toybinprog
install -m 755 toybinprog toybinprog-1.0/usr/bin
install -m 644 toybinprog.conf toybinprog-1.0/etc/toybinprog/

tar -zcvf toybinprog-1.0.tar.gz toybinprog-1.0/

3. Copy to the sources dir

cp toybinprog-1.0.tar.gz SOURCES/

cat <<EOF > SPECS/toybinprog.spec
# Don't try fancy stuff like debuginfo, which is useless on binary-only
# packages. Don't strip binary too
# Be sure buildpolicy set to do nothing

UPDATED

For python 3, you should use items() instead of iteritems()

PYTHON 2

for attr, value in k.__dict__.iteritems():
        print attr, value

PYTHON 3

for attr, value in k.__dict__.items():
        print(attr, value)

This will print

'names', [a list with names]
'tweet', [a list with tweet]

My case is that when I tap enable remote JS debugging, it will launch chrome, but can not connect to it.

I have tried to run:

adb reverse tcp:8081 tcp:8081 

, did but not work.

I uninstalled my chrome totally and install a new one. And it works.

How about something like this:

for (int row = 0; row < 3; row ++)
    for (int col = 0; col < 3; col++)
        table[row][col] = (char) ('1' + row * 3 + col);

The following complete Java program:

class Test {
    public static void main(String[] args) {
        char[][] table = new char[3][3];
        for (int row = 0; row < 3; row ++)
            for (int col = 0; col < 3; col++)
                table[row][col] = (char) ('1' + row * 3 + col);

        for (int row = 0; row < 3; row ++)
            for (int col = 0; col < 3; col++)
                System.out.println (table[row][col]);
    }
}

outputs:

1
2
3
4
5
6
7
8
9

This works because the digits in Unicode are consecutive starting at \u0030 (which is what you get from '0').

The expression '1' + row * 3 + col (where you vary row and col between 0 and 2 inclusive) simply gives you a character from 1 to 9.

Obviously, this won't give you the character 10 (since that's two characters) if you go further but it works just fine for the 3x3 case. You would have to change the method of generating the array contents at that point such as with something like:

String[][] table = new String[5][5];
for (int row = 0; row < 5; row ++)
    for (int col = 0; col < 5; col++)
        table[row][col] = String.format("%d", row * 5 + col + 1);

As there might be a number of operations to do on an ObservableCollection for example Clear first then AddRange and then insert "All" item for a ComboBox I ended up with folowing solution:

public static class LinqExtensions
{
    public static ICollection<T> AddRange<T>(this ICollection<T> source, IEnumerable<T> addSource)
    {
        foreach(T item in addSource)
        {
            source.Add(item);
        }

        return source;
    }
}

public class ExtendedObservableCollection<T>: ObservableCollection<T>
{
    public void Execute(Action<IList<T>> itemsAction)
    {
        itemsAction(Items);
        OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset));
    }
}

And example how to use it:

MyDogs.Execute(items =>
{
    items.Clear();
    items.AddRange(Context.Dogs);
    items.Insert(0, new Dog { Id = 0, Name = "All Dogs" });
});

The Reset notification will be called only once after Execute is finished processing the underlying list.

I had a hard time finding a non-JQUERY answer. Thanks to Stas for putting me on the track.

Chrome: If you don't need cross browser support, you can just use a blacklist, rather than whitelisting. This pure JS version works in Chrome, but not in IE. Not sure about FF.

In Chrome (ver. 36, mid 2014), keypresses not on an input or contenteditable element seem to be targeted to <BODY>. This makes it possible use a blacklist, which I prefer to whitelisting. IE uses the last click target - so it might be a div or anything else. That makes this useless in IE.

window.onkeydown = function(event) {
    if (event.keyCode == 8) {
    //alert(event.target.tagName); //if you want to see how chrome handles keypresses not on an editable element
        if (event.target.tagName == 'BODY') {
            //alert("Prevented Navigation");
            event.preventDefault();
        }
    }
}  

Cross Browser: For pure javascript, I found Stas' answer to be the best. Adding one more condition check for contenteditable made it work for me*:

document.onkeydown = function(e) {stopDefaultBackspaceBehaviour(e);}
document.onkeypress = function(e) {stopDefaultBackspaceBehaviour(e);}

function stopDefaultBackspaceBehaviour(event) {
    var event = event || window.event;
    if (event.keyCode == 8) {
        var elements = "HTML, BODY, TABLE, TBODY, TR, TD, DIV";
        var d = event.srcElement || event.target;
        var regex = new RegExp(d.tagName.toUpperCase());
        if (d.contentEditable != 'true') { //it's not REALLY true, checking the boolean value (!== true) always passes, so we can use != 'true' rather than !== true/
            if (regex.test(elements)) {
                event.preventDefault ? event.preventDefault() : event.returnValue = false;
            }
        }
    }
}

*Note that IEs [edit: and Spartan/TechPreview] have a "feature" that makes table-related elements uneditable. If you click one of those and THEN press backspace, it WILL navigate back. If you don't have editable <td>s, this is not an issue.

The terms resource and endpoint are often used synonymously. But in fact they do not mean the same thing.

The term endpoint is focused on the URL that is used to make a request.
The term resource is focused on the data set that is returned by a request.

Now, the same resource can often be accessed by multiple different endpoints.
Also the same endpoint can return different resources, depending on a query string.

Let us see some examples:

Different endpoints accessing the same resource

Have a look at the following examples of different endpoints:

/api/companies/5/employees/3
/api/v2/companies/5/employees/3
/api/employees/3

They obviously could all access the very same resource in a given API.

Also an existing API could be changed completely. This could lead to new endpoints that would access the same old resources using totally new and different URLs:

/api/employees/3
/new_api/staff/3

One endpoint accessing different resources

If your endpoint returns a collection, you could implement searching/filtering/sorting using query strings. As a result the following URLs all use the same endpoint (/api/companies), but they can return different resources (or resource collections, which by definition are resources in themselves):

/api/companies
/api/companies?sort=name_asc
/api/companies?location=germany
/api/companies?search=siemens

Based on Adam Markowitz's answer above, following worked for me:

process = new Process();
process.StartInfo = new ProcessStartInfo("cmd.exe", "/k \"" + CmdFilePath + "\"");
process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
//process.StartInfo.UseShellExecute = false;
//process.StartInfo.CreateNoWindow = true;
process.Start();

use RowDataBound function to bind data with a perticular cell, and to get control use (ASP Control Name like DropDownList) GridView.FindControl("Name of Control")

You should highly consider using an ORDER BY if you intend to LIMIT your UPDATE, because otherwise it will update in the ordering of the table, which might not be correct.

But as Will A said, it only allows limit on row_count, not offset.

You can also use MyGeneration (free tool) to write your own sql generated scripts. There is a "insert into" script for SQL Server included in MyGeneration, which can be easily changed to run under Oracle.

Thanks for the great answers! Fastest way to get a few one-off files to Colab from Google drive: Load the Drive helper and mount

from google.colab import drive

This will prompt for authorization.

drive.mount('/content/drive')

Open the link in a new tab-> you will get a code - copy that back into the prompt you now have access to google drive check:

!ls "/content/drive/My Drive"

then copy file(s) as needed:

!cp "/content/drive/My Drive/xy.py" "xy.py"

confirm that files were copied:

!ls

I use the following to create a temp exact as the table but without the identity:

SELECT TOP 0 CONVERT(INT,0)myid,* INTO #temp FROM originaltable

ALTER TABLE #temp DROP COLUMN id

EXEC tempdb.sys.sp_rename N'#temp.myid', N'id', N'COLUMN'

Gets a warning about renames but no big deal. I use this on production class systems. Helps make sure the copy will follow any future table modifications and the temp produced is capable of getting rows additional times within a task. Please note that the PK constraint is also removed - if you need it you can add it at the end.

httpcomponents-client-4.0.1 worked for me. However, I had to add the external jar apache-mime4j-0.6.jar (org.apache.james.mime4j) otherwise reqEntity.addPart("bin", bin); would not compile. Now it's working like charm.

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

Recently I import my project into Android studio, a part of R are marked in red with the error meesage "cannot resolve symbol R",but the compilation succeeds and the application runs.

Develop evirment:

• IDE: Android studio 3.1.2
• System: Mac Os

Solution:

step1:

Find the configuration file for Android studio
My path:

/Applications/Android Studio.app/Contents/bin/idea.properties

step2:

Change 2500:

idea.max.intellisense.filesize=2500  

to 5000 or more:

idea.max.intellisense.filesize=5000  

With xidel:

xidel -s input.xml -e 'serialize(.,{"indent":true()})'
<root>
  <foo a="b">lorem</foo>
  <bar value="ipsum"/>
</root>

Or file:write("output.xml",.,{"indent":true()}) to save to a file.

It could be because of couple of Browser settings. Try with these options checked..

Tools > Internet Options > Advanced > Enable Integrated Windows Authentication (works with Integrated Windows Authentication set on IIS)

Tools > Internet Options> Security > Local Intranet > Custom Level > Automatic Logon

Worst case, try adding localhost to the Trusted sites.

If you are in a network, you can also try debugging by getting a network trace. Could be because of some proxy trying to authenticate.

If you like the method in the link you've posted, have a look at Git Flow.

It's a set of scripts he created for that workflow.

But to answer your question:

$ git checkout -b myFeature dev

Creates MyFeature branch off dev. Do your work and then

$ git commit -am "Your message"

Now merge your changes to dev without a fast-forward

$ git checkout dev
$ git merge --no-ff myFeature

Now push changes to the server

$ git push origin dev
$ git push origin myFeature

And you'll see it how you want it.

For trimming, use boost string algorithms:

#include <boost/algorithm/string.hpp>

using namespace std;
using namespace boost;

// ...

string str1(" hello world! ");
trim(str1);      // str1 == "hello world!"

You're better off looking at argparse for argument parsing.

http://docs.python.org/dev/library/argparse.html

Just makes it easy, no need to do the heavy lifting yourself.

Here is a snippet from me in testing... obviously passing via get to the script may not be the best... should post or just send an id and grab guid from db... anyhow.. this worked. I take the URL and convert it to a path.

// Initialize a file URL to the variable
$file = $_GET['url'];
$file = str_replace(Polepluginforrvms_Plugin::$install_url, $DOC_ROOT.'/pole-permitter/', $file );

$quoted = sprintf('"%s"', addcslashes(basename($file), '"\\'));
$size   = filesize($file);

header( "Content-type: application/octet-stream" );
header( "Content-Disposition: attachment; filename={$quoted}" );
header( "Content-length: " . $size );
header( "Pragma: no-cache" );
header( "Expires: 0" );
readfile( "{$file}" );

For getting the done Button

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

and

android:inputType="text" in the xml

For handling on done clicked from keyboard

    editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event){
            if(actionId == EditorInfo.IME_ACTION_DONE){
                // Your action on done
                return true;
            }
            return false;
        }
    });

Generally it means that you are providing an index for which a list element does not exist.

E.g, if your list was [1, 3, 5, 7], and you asked for the element at index 10, you would be well out of bounds and receive an error, as only elements 0 through 3 exist.

To create a new object you can either use placement new, as mentioned above, or have your class implement a clone() method that creates a copy of the object. You can then call this clone method using a member function pointer as explained above to create new instances of the object. The advantage of clone is that sometimes you may be working with a pointer to a base class where you don't know the type of the object. In this case a clone() method can be easier to use. Also, clone() will let you copy the state of the object if that is what you want.

Just a small correction to the first answer in this thread.

Even for Stack, you need to create new object with generics if you are using Stack from java util packages.

Right usage:
    Stack<Integer> s = new Stack<Integer>();
    Stack<String> s1 = new Stack<String>();

    s.push(7);
    s.push(50);

    s1.push("string");
    s1.push("stack");

if used otherwise, as mentioned in above post, which is:

    /*
    Stack myStack = new Stack();
    // add any type of elements (String, int, etc..)
    myStack.push("Hello");
    myStack.push(1);
    */

Although this code works fine, has unsafe or unchecked operations which results in error.

ResizeStart and ResizeEnd events for window

http://jsfiddle.net/04fLy8t4/

I implemented function which trig two events on user DOM element:

1. resizestart
2. resizeend

Code:

var resizeEventsTrigger = (function () {
    function triggerResizeStart($el) {
        $el.trigger('resizestart');
        isStart = !isStart;
    }

    function triggerResizeEnd($el) {
        clearTimeout(timeoutId);
        timeoutId = setTimeout(function () {
            $el.trigger('resizeend');
            isStart = !isStart;
        }, delay);
    }

    var isStart = true;
    var delay = 200;
    var timeoutId;

    return function ($el) {
        isStart ? triggerResizeStart($el) : triggerResizeEnd($el);
    };

})();

$("#my").on('resizestart', function () {
    console.log('resize start');
});
$("#my").on('resizeend', function () {
    console.log('resize end');
});

window.onresize = function () {
    resizeEventsTrigger( $("#my") );
};

TL;DR:

sudo apt-get install nodejs-legacy

First of all let me clarify the situation a bit. In summer 2012 Debian maintainers decided to rename Node.js executable to prevent some kind of namespace collision with another package. It was very hard decision for Debian Technical Committee, because it breaks backward compatibility.

The following is a quote from Committee resolution draft, published in Debian mailing list:

1. The nodejs package shall be changed to provide /usr/bin/nodejs, not /usr/bin/node. The package should declare a Breaks: relationship with any packages in Debian that reference /usr/bin/node.

2. The nodejs source package shall also provide a nodejs-legacy binary package at Priority: extra that contains /usr/bin/node as a symlink to /usr/bin/nodejs. No package in the archive may depend on or recommend the nodejs-legacy package, which is provided solely for upstream
   compatibility. This package declares shall also declare a Conflicts: relationship with the node package.

<...>

Paragraph 2 is the actual solution for OP's issue. OP should try to install this package instead of doing symlink by hand. Here is a link to this package in Debian package index website.

It can be installed using sudo apt-get install nodejs-legacy.

I have not found any information about adopting the whole thing by NPM developers, but I think npm package will be fixed on some point and nodejs-legacy become really legacy.

the correct answer is good , but

OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());

not work for me , instead of it , use :

byte[] outputBytes = rootJsonObject.getBytes("UTF-8");
OutputStream os = con.getOutputStream();
os.write(outputBytes);

Update: as per the comment on this question, the problem has been solved:

That is easy: the first file has CRLF line-ends (windows), the second LF (Unix). The file util (available in git\usr\bin) will show you that (file a b will reply something like a: ASCII text, with CRLF line terminators b: ASCII text)

Original answer below:

The diff you show does not show a single different line. Can you post .git/config (or better git config -l).

You might have some whitespace ignores activated

You should try to disable core.whitespace=fix,-indent-with-non-tab,trailing-space,cr-at-eol;

also

git show HEAD:myfile|md5sum
md5sum myfile

could be used to verify that the files are in fact different. Using external diff could work as well

git show HEAD:myfile > /tmp/myfile.HEAD

diff -u myfile /tmp/myfile.HEAD

# or if you prefer an interactive tool like e.g.:
vim -d myfile /tmp/myfile.HEAD

Be careful if your model type is String because the second parameter of View(string, string) is masterName, not model. You may need to call the overload with object(model) as the second paramater:

Not correct :

protected ActionResult ShowMessageResult(string msg)
{
    return View("Message",msg);
}

Correct :

protected ActionResult ShowMessageResult(string msg)
{
    return View("Message",(object)msg);
}

OR (provided by bradlis7):

protected ActionResult ShowMessageResult(string msg)
{
    return View("Message",model:msg);
}

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.

For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

Using this code you can copy any class object to another class object for same name and same type of properties.

JavaScriptSerializer JsonConvert = new JavaScriptSerializer(); 
string serializeString = JsonConvert.Serialize(objectEntity);
objectViewModel objVM = JsonConvert.Deserialize<objectViewModel>(serializeString);

Interesting. I got the same problem as you when I wrote a test version.

The solution is to use jquery's ability to chain and do:

$(this).width(500).css("text-align", "center");

Interesting find though.

To expand a bit, the following does not work

$(this).width(500);
$(this).css("text-align", "center");

and results only in the width being set on the style. Chaining the two, as I suggested above, does seem to work.

I was searching for a solution to get the last foldername where the file is located, I just used split two times, to get the right part. It's not the question but google transfered me here.

pathname = "/folderA/folderB/folderC/folderD/filename.py"
head, tail = os.path.split(os.path.split(pathname)[0])
print(head + "   "  + tail)

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">

I have seen most of the people saying explicit parent to child casting is not possible, that actually is not true. Let's take a revised start and try proving it by examples.

As we know in .net all castings have two broad categories.

1. For Value type
2. For Reference type (in your case its reference type)

Reference type has further three main situational cases in which any scenario can lie.

Child to Parent (Implicit casting - Always successful)

Case 1. Child to any direct or indirect parent

Employee e = new Employee();
Person p = (Person)e; //Allowed

Parent to Child (Explicit casting - Can be successful)

Case 2. Parent variable holding parent object (Not allowed)

Person p = new Person();  // p is true Person object
Employee e = (Employee)p; //Runtime err : InvalidCastException <-------- Yours issue

Case 3. Parent variable holding child object (Always Successful)

Note: Because objects has polymorphic nature, it is possible for a variable of a parent class type to hold a child type.

Person p = new Employee(); // p actually is Employee
Employee e = (Employee)p; // Casting allowed

Conclusion : After reading above all, hope it will make sense now like how parent to child conversion is possible(Case 3).

Answer To The Question :

Your answer is in case 2.Where you can see such casting is not allowed by OOP and you are trying to violate one of OOP's basic rule.So always choose safe path.

Further more, to avoid such exceptional situations .net has recommended using is/as operators those will help you to take informed decisions and provide safe casting.

Use pngcrush to remove the incorrect sRGB profile from the png file:

pngcrush -ow -rem allb -reduce file.png

• -ow will overwrite the input file
• -rem allb will remove all ancillary chunks except tRNS and gAMA
• -reduce does lossless color-type or bit-depth reduction

In the console output you should see Removed the sRGB chunk, and possibly more messages about chunk removals. You will end up with a smaller, optimized PNG file. As the command will overwrite the original file, make sure to create a backup or use version control.

In some shells like fish you can use the ** globbing to do that:

svn add **

I have no idea why Enums are not support natively by Python. The best way I've found to emulate them is by overridding _ str _ and _ eq _ so you can compare them and when you use print() you get the string instead of the numerical value.

class enumSeason():
    Spring = 0
    Summer = 1
    Fall = 2
    Winter = 3
    def __init__(self, Type):
        self.value = Type
    def __str__(self):
        if self.value == enumSeason.Spring:
            return 'Spring'
        if self.value == enumSeason.Summer:
            return 'Summer'
        if self.value == enumSeason.Fall:
            return 'Fall'
        if self.value == enumSeason.Winter:
            return 'Winter'
    def __eq__(self,y):
       return self.value==y.value

Usage:

>>> s = enumSeason(enumSeason.Spring)

>>> print(s)

Spring

Just use it like it was an object you defined. i.e.

$trends = $json_output->trends;

Count number of list elements

alert($("#mylist > li").length);

 private FirebaseDatabase firebaseDatabase=  FirebaseDatabase.getInstance();
    private DatabaseReference databaseReference=  firebaseDatabase.getReference();
    private DatabaseReference mChildReference= databaseReference.child("data");

  mChildReference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                for(DataSnapshot ds : dataSnapshot.getChildren()) {
                    User commandObject = ds.getValue(User.class);
                    Log.d("TAG", commandObject.getMsg());
                }
                Toast.makeText(MainActivity.this,dataSnapshot.toString(),Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });

This will help you, you just have to create a model class containing String msg.

I couldn't gain yet the survey of an inherited extensive code. And exact this problem bugged me for months. Many approches with DoEnvents were not helpful. Above answer helped. Placeing this Sub in meaningful positions in the code worked even in combination with progress bar

Sub ForceScreenUpdate()
    Application.ScreenUpdating = True
    Application.EnableEvents = True
    Application.Wait Now + #12:00:01 AM#
    Application.ScreenUpdating = False
    Application.EnableEvents = False
End Sub

Yes, use mktemp.

It will create a temporary file inside a folder that is designed for storing temporary files, and it will guarantee you a unique name. It outputs the name of that file:

> mktemp
/tmp/tmp.xx4mM3ePQY
>

You can use date to get time and date of a day:

[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013

Also hwclock would do:

[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST  -0.516080 seconds

For customized output, you can either redirect the output of date to something like awk, or write your own program to do that.

Remember to put your own executable scripts/binary into your PATH (e.g. /usr/bin) to make it invokable anywhere.

Instead of copy/pasting the code from the tutorial, use the code suggestion in the IDE. Start typing "extends ActionBar..." it will propose "ActionBarActivity" click enter. It worked for me!

Alternative

Using the example from Sarfraz above.

<div class="res">
    <a class="info_link" href="~/Resumes/Resumes1271354404687.docx">
        ~/Resumes/Resumes1271354404687.docx
    </a>
</div>

For href:

$(function(){
  $('.res').on('click', '.info_link', function(){
    alert($(this)[0].href);
  });
});

When you start Android studio Look for Profile or Debug apk.

After clicking you get the option to browse for the saved apk and you will be bale to later run it using emulator

You could fill the C Column with variations on the following formula:

=IF(ISERROR(MATCH(A1,$B:$B,0)),"",A1)

Then C would only contain values that were in A and C.

Mine is animated:

$(this).animate({
    opacity: 0
}, 100, function() {
    // Callback
    $(this).css("background-image", "url(" + new_img + ")").promise().done(function(){
        // Callback of the callback :)
        $(this).animate({
            opacity: 1
        }, 600)
    });    
});

Use !empty() instead of isset(). Because isset() will always return true in your case.

if (!empty($_POST["mail"])) {
    echo "Yes, mail is entered";    
} else {  
    echo "No, mail is not entered";
}

You can now accomplish this in Chrome by right clicking on the object and selecting "Store as Global Variable": http://www.youtube.com/watch?v=qALFiTlVWdg

cat file.txt | grep "company_name" | cut -d '=' -f 2 | cut -d ';' -f 1

If you have Task constructor, then we may extract Thread from the Task, and invoke thread.abort.

Thread th = null;

Task.Factory.StartNew(() =>
{
    th = Thread.CurrentThread;

    while (true)
    {
        Console.WriteLine(DateTime.UtcNow);
    }
});

Thread.Sleep(2000);
th.Abort();
Console.ReadKey();

This worked out for me. I made a custom php code to force redirect it to https. Just include this code on the header.php

<?php
if (isset($_SERVER['HTTPS']) &&
    ($_SERVER['HTTPS'] == 'on' || $_SERVER['HTTPS'] == 1) ||
    isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &&
    $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') {
  $protocol = 'https://';
}
else {
  $protocol = 'http://';
}
$notssl = 'http://';
if($protocol==$notssl){
    $url = "https://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";?>
    <script> 
    window.location.href ='<?php echo $url?>';
    </script> 
 <?php } ?>

Unless you're trying to upload the file using ajax, just submit the form to /upload/image.

<form enctype="multipart/form-data" action="/upload/image" method="post">
    <input id="image-file" type="file" />
</form>

If you do want to upload the image in the background (e.g. without submitting the whole form), you can use ajax:

• Asynchronous file upload (AJAX file upload) using jsp and javascript
• jQuery Ajax File Upload
• Ajax using file upload

The reason why this happened to me was that a remote server was allowing only certain IP addressed but not its own, and I was trying to render the images from the server's URLs... so everything would simply halt, displaying the timeout error that you had...

Make sure that either the server is allowing its own IP, or that you are rendering things from some remote URL that actually exists.

another way

$('input:radio[name=theme]').filter(":checked").val()

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

Here is a more complete answer with regard to InnoDB. It is a bit of a lengthy process, but can be worth the effort.

Keep in mind that /var/lib/mysql/ibdata1 is the busiest file in the InnoDB infrastructure. It normally houses six types of information:

• Table Data
• Table Indexes
• MVCC (Multiversioning Concurrency Control) Data
  • Rollback Segments
  • Undo Space
• Table Metadata (Data Dictionary)
• Double Write Buffer (background writing to prevent reliance on OS caching)
• Insert Buffer (managing changes to non-unique secondary indexes)
• See the Pictorial Representation of ibdata1

InnoDB Architecture

Many people create multiple ibdata files hoping for better disk-space management and performance, however that belief is mistaken.

Can I run OPTIMIZE TABLE ?

Unfortunately, running OPTIMIZE TABLE against an InnoDB table stored in the shared table-space file ibdata1 does two things:

• Makes the table’s data and indexes contiguous inside ibdata1
• Makes ibdata1 grow because the contiguous data and index pages are appended to ibdata1

You can however, segregate Table Data and Table Indexes from ibdata1 and manage them independently.

Can I run OPTIMIZE TABLE with innodb_file_per_table ?

Suppose you were to add innodb_file_per_table to /etc/my.cnf (my.ini). Can you then just run OPTIMIZE TABLE on all the InnoDB Tables?

Good News : When you run OPTIMIZE TABLE with innodb_file_per_table enabled, this will produce a .ibd file for that table. For example, if you have table mydb.mytable witha datadir of /var/lib/mysql, it will produce the following:

• /var/lib/mysql/mydb/mytable.frm
• /var/lib/mysql/mydb/mytable.ibd

The .ibd will contain the Data Pages and Index Pages for that table. Great.

Bad News : All you have done is extract the Data Pages and Index Pages of mydb.mytable from living in ibdata. The data dictionary entry for every table, including mydb.mytable, still remains in the data dictionary (See the Pictorial Representation of ibdata1). YOU CANNOT JUST SIMPLY DELETE ibdata1 AT THIS POINT !!! Please note that ibdata1 has not shrunk at all.

InnoDB Infrastructure Cleanup

To shrink ibdata1 once and for all you must do the following:

1. Dump (e.g., with mysqldump) all databases into a .sql text file (SQLData.sql is used below)

2. Drop all databases (except for mysql and information_schema) CAVEAT : As a precaution, please run this script to make absolutely sure you have all user grants in place:

   mkdir /var/lib/mysql_grants
   cp /var/lib/mysql/mysql/* /var/lib/mysql_grants/.
   chown -R mysql:mysql /var/lib/mysql_grants
   

3. Login to mysql and run SET GLOBAL innodb_fast_shutdown = 0; (This will completely flush all remaining transactional changes from ib_logfile0 and ib_logfile1)

4. Shutdown MySQL

5. Add the following lines to /etc/my.cnf (or my.ini on Windows)

   [mysqld]
   innodb_file_per_table
   innodb_flush_method=O_DIRECT
   innodb_log_file_size=1G
   innodb_buffer_pool_size=4G
   

   (Sidenote: Whatever your set for innodb_buffer_pool_size, make sure innodb_log_file_size is 25% of innodb_buffer_pool_size.

   Also: innodb_flush_method=O_DIRECT is not available on Windows)

6. Delete ibdata* and ib_logfile*, Optionally, you can remove all folders in /var/lib/mysql, except /var/lib/mysql/mysql.

7. Start MySQL (This will recreate ibdata1 [10MB by default] and ib_logfile0 and ib_logfile1 at 1G each).

8. Import SQLData.sql

Now, ibdata1 will still grow but only contain table metadata because each InnoDB table will exist outside of ibdata1. ibdata1 will no longer contain InnoDB data and indexes for other tables.

For example, suppose you have an InnoDB table named mydb.mytable. If you look in /var/lib/mysql/mydb, you will see two files representing the table:

• mytable.frm (Storage Engine Header)
• mytable.ibd (Table Data and Indexes)

With the innodb_file_per_table option in /etc/my.cnf, you can run OPTIMIZE TABLE mydb.mytable and the file /var/lib/mysql/mydb/mytable.ibd will actually shrink.

I have done this many times in my career as a MySQL DBA. In fact, the first time I did this, I shrank a 50GB ibdata1 file down to only 500MB!

Give it a try. If you have further questions on this, just ask. Trust me; this will work in the short term as well as over the long haul.

CAVEAT

At Step 6, if mysql cannot restart because of the mysql schema begin dropped, look back at Step 2. You made the physical copy of the mysql schema. You can restore it as follows:

mkdir /var/lib/mysql/mysql
cp /var/lib/mysql_grants/* /var/lib/mysql/mysql
chown -R mysql:mysql /var/lib/mysql/mysql

Go back to Step 6 and continue

UPDATE 2013-06-04 11:13 EDT

With regard to setting innodb_log_file_size to 25% of innodb_buffer_pool_size in Step 5, that's blanket rule is rather old school.

Back on July 03, 2006, Percona had a nice article why to choose a proper innodb_log_file_size. Later, on Nov 21, 2008, Percona followed up with another article on how to calculate the proper size based on peak workload keeping one hour's worth of changes.

I have since written posts in the DBA StackExchange about calculating the log size and where I referenced those two Percona articles.

• Aug 27, 2012 : Proper tuning for 30GB InnoDB table on server with 48GB RAM
• Jan 17, 2013 : MySQL 5.5 - Innodb - innodb_log_file_size higher than 4GB combined?

Personally, I would still go with the 25% rule for an initial setup. Then, as the workload can more accurate be determined over time in production, you could resize the logs during a maintenance cycle in just minutes.

Got same error when doing a 'git pull' and this is how I fixed it.

1. Change repo to HTTPS
2. Run command git config --system --unset credential.helper
3. Run command git config --system --add credential.helper manager
4. Test command git pull
5. Enter credentials in the login window that pops up.
6. Git pull completed successfully.

In Java-8 you can use IntStream to produce a stream of numbers that you want to repeat, and then convert it to array. This approach produces an expression suitable for use in an initializer:

int[] data = IntStream.generate(() -> value).limit(size).toArray();

Above, size and value are expressions that produce the number of items that you want tot repeat and the value being repeated.

Demo.

An effective iterative solution over a Map is a for loop from Java 5 through Java 7. Here it is:

for (String key : phnMap.keySet()) {
    System.out.println("Key: " + key + " Value: " + phnMap.get(key));
}

From Java 8 you can use a lambda expression to iterate over a Map. It is an enhanced forEach

phnMap.forEach((k,v) -> System.out.println("Key: " + k + " Value: " + v));

If you want to write a conditional for lambda you can write it like this:

phnMap.forEach((k,v)->{
    System.out.println("Key: " + k + " Value: " + v);
    if("abc".equals(k)){
        System.out.println("Hello abc");
    }
});

I have two demos, one with jQuery and one without. Neither use date functions and are about as simple as it gets.

Demo with vanilla JavaScript

function startTimer(duration, display) {_x000D_
    var timer = duration, minutes, seconds;_x000D_
    setInterval(function () {_x000D_
        minutes = parseInt(timer / 60, 10);_x000D_
        seconds = parseInt(timer % 60, 10);_x000D_
_x000D_
        minutes = minutes < 10 ? "0" + minutes : minutes;_x000D_
        seconds = seconds < 10 ? "0" + seconds : seconds;_x000D_
_x000D_
        display.textContent = minutes + ":" + seconds;_x000D_
_x000D_
        if (--timer < 0) {_x000D_
            timer = duration;_x000D_
        }_x000D_
    }, 1000);_x000D_
}_x000D_
_x000D_
window.onload = function () {_x000D_
    var fiveMinutes = 60 * 5,_x000D_
        display = document.querySelector('#time');_x000D_
    startTimer(fiveMinutes, display);_x000D_
};

<body>_x000D_
    <div>Registration closes in <span id="time">05:00</span> minutes!</div>_x000D_
</body>

Demo with jQuery

function startTimer(duration, display) {
    var timer = duration, minutes, seconds;
    setInterval(function () {
        minutes = parseInt(timer / 60, 10);
        seconds = parseInt(timer % 60, 10);

        minutes = minutes < 10 ? "0" + minutes : minutes;
        seconds = seconds < 10 ? "0" + seconds : seconds;

        display.text(minutes + ":" + seconds);

        if (--timer < 0) {
            timer = duration;
        }
    }, 1000);
}

jQuery(function ($) {
    var fiveMinutes = 60 * 5,
        display = $('#time');
    startTimer(fiveMinutes, display);
});

However if you want a more accurate timer that is only slightly more complicated:

function startTimer(duration, display) {_x000D_
    var start = Date.now(),_x000D_
        diff,_x000D_
        minutes,_x000D_
        seconds;_x000D_
    function timer() {_x000D_
        // get the number of seconds that have elapsed since _x000D_
        // startTimer() was called_x000D_
        diff = duration - (((Date.now() - start) / 1000) | 0);_x000D_
_x000D_
        // does the same job as parseInt truncates the float_x000D_
        minutes = (diff / 60) | 0;_x000D_
        seconds = (diff % 60) | 0;_x000D_
_x000D_
        minutes = minutes < 10 ? "0" + minutes : minutes;_x000D_
        seconds = seconds < 10 ? "0" + seconds : seconds;_x000D_
_x000D_
        display.textContent = minutes + ":" + seconds; _x000D_
_x000D_
        if (diff <= 0) {_x000D_
            // add one second so that the count down starts at the full duration_x000D_
            // example 05:00 not 04:59_x000D_
            start = Date.now() + 1000;_x000D_
        }_x000D_
    };_x000D_
    // we don't want to wait a full second before the timer starts_x000D_
    timer();_x000D_
    setInterval(timer, 1000);_x000D_
}_x000D_
_x000D_
window.onload = function () {_x000D_
    var fiveMinutes = 60 * 5,_x000D_
        display = document.querySelector('#time');_x000D_
    startTimer(fiveMinutes, display);_x000D_
};

<body>_x000D_
    <div>Registration closes in <span id="time"></span> minutes!</div>_x000D_
</body>

Now that we have made a few pretty simple timers we can start to think about re-usability and separating concerns. We can do this by asking "what should a count down timer do?"

• Should a count down timer count down? Yes
• Should a count down timer know how to display itself on the DOM? No
• Should a count down timer know to restart itself when it reaches 0? No
• Should a count down timer provide a way for a client to access how much time is left? Yes

So with these things in mind lets write a better (but still very simple) CountDownTimer

function CountDownTimer(duration, granularity) {
  this.duration = duration;
  this.granularity = granularity || 1000;
  this.tickFtns = [];
  this.running = false;
}

CountDownTimer.prototype.start = function() {
  if (this.running) {
    return;
  }
  this.running = true;
  var start = Date.now(),
      that = this,
      diff, obj;

  (function timer() {
    diff = that.duration - (((Date.now() - start) / 1000) | 0);

    if (diff > 0) {
      setTimeout(timer, that.granularity);
    } else {
      diff = 0;
      that.running = false;
    }

    obj = CountDownTimer.parse(diff);
    that.tickFtns.forEach(function(ftn) {
      ftn.call(this, obj.minutes, obj.seconds);
    }, that);
  }());
};

CountDownTimer.prototype.onTick = function(ftn) {
  if (typeof ftn === 'function') {
    this.tickFtns.push(ftn);
  }
  return this;
};

CountDownTimer.prototype.expired = function() {
  return !this.running;
};

CountDownTimer.parse = function(seconds) {
  return {
    'minutes': (seconds / 60) | 0,
    'seconds': (seconds % 60) | 0
  };
};

So why is this implementation better than the others? Here are some examples of what you can do with it. Note that all but the first example can't be achieved by the startTimer functions.

An example that displays the time in XX:XX format and restarts after reaching 00:00

An example that displays the time in two different formats

An example that has two different timers and only one restarts

An example that starts the count down timer when a button is pressed

If you are developing for Windows, the com0com project might be, what you are looking for.

It provides pairs of virtual COM ports that are linked via a nullmodem connetion. You can then use your favorite terminal application or whatever you like to send data to one COM port and recieve from the other one.

EDIT:

As Thomas pointed out the project lacks of a signed driver, which is especially problematic on certain Windows version (e.g. Windows 7 x64).

There are a couple of unofficial com0com versions around that do contain a signed driver. One recent verion (3.0.0.0) can be downloaded e.g. from here.

In the case of no repeats and no order, the following EqualityComparer can be used to allow collections as dictionary keys:

public class SetComparer<T> : IEqualityComparer<IEnumerable<T>> 
where T:IComparable<T>
{
    public bool Equals(IEnumerable<T> first, IEnumerable<T> second)
    {
        if (first == second)
            return true;
        if ((first == null) || (second == null))
            return false;
        return first.ToHashSet().SetEquals(second);
    }

    public int GetHashCode(IEnumerable<T> enumerable)
    {
        int hash = 17;

        foreach (T val in enumerable.OrderBy(x => x))
            hash = hash * 23 + val.GetHashCode();

        return hash;
    }
}

Here is the ToHashSet() implementation I used. The hash code algorithm comes from Effective Java (by way of Jon Skeet).

I have created an simple library for that:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class exceptions {

    public function checkForError() {
        get_instance()->load->database();
        $error = get_instance()->db->error();
        if ($error['code'])
            throw new MySQLException($error);
    }
}

abstract class UserException extends Exception {
    public abstract function getUserMessage();
}

class MySQLException extends UserException {
    private $errorNumber;
    private $errorMessage;

    public function __construct(array $error) {
        $this->errorNumber = "Error Code(" . $error['code'] . ")";
        $this->errorMessage = $error['message'];
    }

    public function getUserMessage() {
        return array(
            "error" => array (
                "code" => $this->errorNumber,
                "message" => $this->errorMessage
            )
        );
    }

}

The example query:

function insertId($id){
    $data = array(
        'id' => $id,
    );

    $this->db->insert('test', $data);
    $this->exceptions->checkForError();
    return $this->db->insert_id();
}

And I can catch it this way in my controller:

 try {
     $this->insertThings->insertId("1");
 } catch (UserException $error){
     //do whatever you want when there is an mysql error

 }

You can use a LEFT JOIN with a "VALUES ('f',1),('p',2),('a',3),('i',4)" and use the second column in your order-by expression. Postgres will use a Hash Join which will be much faster than a huge CASE if you have a lot of values. And it is easier to autogenerate.

If this ordering information is fixed, then it should have its own table.

You may want to comment out the DL is deprecated, please use Fiddle warning at

C:\Ruby200\lib\ruby\2.0.0\dl.rb

since it’s annoying and you are not the irb/pry or some other gems code owner

You can also use vector::insert.

std::vector<int> v;
int a[5] = {2, 5, 8, 11, 14};

v.insert(v.end(), a, a+5);

Edit:

Of course, in real-world programming you should use:

v.insert(v.end(), a, a+(sizeof(a)/sizeof(a[0])));  // C++03
v.insert(v.end(), std::begin(a), std::end(a));     // C++11

I've found that the command was wrong, correct command contains "broadcast" instead of "start":

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test from adb" -n com.whereismywifeserver/.IntentReceiver

If you can, I strongly suggest you tar and bzip (or gzip, whatever floats your boat) the directory on the remote machine—for a directory of any significant size, the bandwidth savings will probably be worth the time to zip/unzip.

This is an adapted version of the answer given by Vivien Barousse with the update from Vulcan applied. In this example I use sliders to dynamically retreive the RGB values from three sliders and display that color in a rectangle. Then in method toHex() I use the values to create a color and display the respective Hex color code.

This example does not include the proper constraints for the GridBagLayout. Though the code will work, the display will look strange.

public class HexColor
{

  public static void main (String[] args)
  {
   JSlider sRed = new JSlider(0,255,1);
   JSlider sGreen = new JSlider(0,255,1);
   JSlider sBlue = new JSlider(0,255,1);
   JLabel hexCode = new JLabel();
   JPanel myPanel = new JPanel();
   GridBagLayout layout = new GridBagLayout();
   JFrame frame = new JFrame();

   //set frame to organize components using GridBagLayout 
   frame.setLayout(layout);

   //create gray filled rectangle 
   myPanel.paintComponent();
   myPanel.setBackground(Color.GRAY);

   //In practice this code is replicated and applied to sGreen and sBlue. 
   //For the sake of brevity I only show sRed in this post.
   sRed.addChangeListener(
         new ChangeListener()
         {
             @Override
             public void stateChanged(ChangeEvent e){
                 myPanel.setBackground(changeColor());
                 myPanel.repaint();
                 hexCode.setText(toHex());
         }
         }
     );
   //add each component to JFrame
   frame.add(myPanel);
   frame.add(sRed);
   frame.add(sGreen);
   frame.add(sBlue);
   frame.add(hexCode);
} //end of main

  //creates JPanel filled rectangle
  protected void paintComponent(Graphics g)
  {
      super.paintComponent(g);
      g.drawRect(360, 300, 10, 10);
      g.fillRect(360, 300, 10, 10);
  }

  //changes the display color in JPanel
  private Color changeColor()
  {
    int r = sRed.getValue();
    int b = sBlue.getValue();
    int g = sGreen.getValue();
    Color c;
    return  c = new Color(r,g,b);
  }

  //Displays hex representation of displayed color
  private String toHex()
  {
      Integer r = sRed.getValue();
      Integer g = sGreen.getValue();
      Integer b = sBlue.getValue();
      Color hC;
      hC = new Color(r,g,b);
      String hex = Integer.toHexString(hC.getRGB() & 0xffffff);
      while(hex.length() < 6){
          hex = "0" + hex;
      }
      hex = "Hex Code: #" + hex;
      return hex;
  }
}

A huge thank you to both Vivien and Vulcan. This solution works perfectly and was super simple to implement.

In rails you can try #blank?.

Warning: it will give you positives when string consists of spaces:

nil.blank? # ==> true
''.blank? # ==> true
'  '.blank? # ==> true
'false'.blank? # ==> false

Just wanted to point it out. Maybe it suits your needs

UPD. why am i getting old questions in my feed? Sorry for necroposting.

There's no "simple command" to do that. You can write a function, or take your choice of several that are available online in various code repositories. I use this:

function get-loggedonuser ($computername){

#mjolinor 3/17/10

$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'

$logontype = @{
"0"="Local System"
"2"="Interactive" #(Local logon)
"3"="Network" # (Remote logon)
"4"="Batch" # (Scheduled task)
"5"="Service" # (Service account logon)
"7"="Unlock" #(Screen saver)
"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}

$logon_sessions = @(gwmi win32_logonsession -ComputerName $computername)
$logon_users = @(gwmi win32_loggedonuser -ComputerName $computername)

$session_user = @{}

$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}


$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)

$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime

$loggedonuser
}

}

it is very easy:

add \documentclass[oneside]{book} and youre fine ;)

In case anyone arrives looking for how to generate a relative path from the rails console

ActionView::Helpers::AssetTagHelper
image_path('my_image.png')
=> "/images/my_image.png"

Or the controller

include ActionView::Helpers::AssetTagHelper
image_path('my_image.png')
=> "/images/my_image.png"

After adding JTextArea into JScrollPane here:

scroll = new JScrollPane(display);

You don't need to add it again into other container like you do:

middlePanel.add(display);

Just remove that last line of code and it will work fine. Like this:

    middlePanel=new JPanel();
    middlePanel.setBorder(new TitledBorder(new EtchedBorder(), "Display Area"));

    // create the middle panel components

    display = new JTextArea(16, 58);
    display.setEditable(false); // set textArea non-editable
    scroll = new JScrollPane(display);
    scroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);

    //Add Textarea in to middle panel
    middlePanel.add(scroll);

JScrollPane is just another container that places scrollbars around your component when its needed and also has its own layout. All you need to do when you want to wrap anything into a scroll just pass it into JScrollPane constructor:

new JScrollPane( myComponent ) 

or set view like this:

JScrollPane pane = new JScrollPane ();
pane.getViewport ().setView ( myComponent );

Additional:

Here is fully working example since you still did not get it working:

public static void main ( String[] args )
{
    JPanel middlePanel = new JPanel ();
    middlePanel.setBorder ( new TitledBorder ( new EtchedBorder (), "Display Area" ) );

    // create the middle panel components

    JTextArea display = new JTextArea ( 16, 58 );
    display.setEditable ( false ); // set textArea non-editable
    JScrollPane scroll = new JScrollPane ( display );
    scroll.setVerticalScrollBarPolicy ( ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS );

    //Add Textarea in to middle panel
    middlePanel.add ( scroll );

    // My code
    JFrame frame = new JFrame ();
    frame.add ( middlePanel );
    frame.pack ();
    frame.setLocationRelativeTo ( null );
    frame.setVisible ( true );
}

And here is what you get:

This can be achieved by creating a drawable xml file containing a list of states for the button. So for example if you create a new xml file called "button.xml" with the following code:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/YOURIMAGE" />
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/gradient" />
    <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/gradient" />
    <item android:drawable="@drawable/YOURIMAGE" />
</selector>

To keep the background image with a darkened appearance on press, create a second xml file and call it gradient.xml with the following code:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <bitmap android:src="@drawable/YOURIMAGE"/>
    </item>
    <item>
        <shape xmlns:android="http://schemas.android.com/apk/res/android">
            <gradient android:angle="90" android:startColor="#880f0f10" android:centerColor="#880d0d0f" android:endColor="#885d5d5e"/>
        </shape>
    </item>
</layer-list>

In the xml of your button set the background to be the button xml e.g.

android:background="@drawable/button"

Hope this helps!

Edit: Changed the above code to show an image (YOURIMAGE) in the button as opposed to a block colour.

Yep! Use the link:

https://m.google.com/app/plus/x/?v=compose&content=YOUR_TEXT

It's SHARE url (not used for plus one) button.

If this will not work (not for me) try this url:

https://plusone.google.com/_/+1/confirm?hl=ru&url=_URL_&title=_TITLE_

Or see this solution:

Adding a Google Plus (one or share) link to an email newsletter

If you think about it the concept behind a dropdown select it's pretty simple. For what you're trying to accomplish, a simple <ul> will do.

<ul id="menu">
    <li>
        <a href="#"><img src="" alt=""/></a> <!-- Selected -->
        <ul>
            <li><a href="#"><img src="" alt=""/></a></li>
            <li><a href="#"><img src="" alt=""/></a></li>
            <li><a href="#"><img src="" alt=""/></a></li>
            <li><a href="#"><img src="" alt=""/></a></li>
        </ul>
    </li>
</ul>

You style it with css and then some simple jQuery will do. I haven't tried this tho:

$('#menu ul li').click(function(){
    var $a = $(this).find('a');
    $(this).parents('#menu').children('li a').replaceWith($a).
});

From MySQL documentation:

The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used. For example, utf8 characters can require up to three bytes per character, so a VARCHAR column that uses the utf8 character set can be declared to be a maximum of 21,844 characters.

Limits for the VARCHAR varies depending on charset used. Using ASCII would use 1 byte per character. Meaning you could store 65,535 characters. Using utf8 will use 3 bytes per character resulting in character limit of 21,844. BUT if you are using the modern multibyte charset utf8mb4 which you should use! It supports emojis and other special characters. It will be using 4 bytes per character. This will limit the number of characters per table to 16,383. Note that other fields such as INT will also be counted to these limits.

Conclusion:

utf8 maximum of 21,844 characters

utf8mb4 maximum of 16,383 characters

As @PavelAnossov answered, the canonical answer, use the word_tokenize function in nltk:

from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)

If your sentence is truly simple enough:

Using the string.punctuation set, remove punctuation then split using the whitespace delimiter:

import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y

As you said, the issue here is not iframe content caching, but iframe url caching.

As of September 2018, it seems the issue still occurs in Chrome but not in Firefox.

I've tried many things (adding a changing GET parameter, clearing the iframe url in onbeforeunload, detecting a "reload from cache" using a cookie, setting up various response headers) and here are the only two solutions that worked from me:

1- Easy way: create your iframe dynamically from javascript

For example:

const iframe = document.createElement('iframe')
iframe.id = ...
...
iframe.src = myIFrameUrl 
document.body.appendChild(iframe)

2- Convoluted way

Server-side, as explained here, disable content caching for the content you serve for the iframe OR for the parent page (either will do).

AND

Set the iframe url from javascript with an additional changing search param, like this:

const url = myIFrameUrl + '?timestamp=' + new Date().getTime()
document.getElementById('my-iframe-id').src = url

(simplified version, beware of other search params)

Use this

import data from './customData.json';

You can use the varStatus attribute like this:-

<c:forEach var="categoryName" items="${categoriesList}" varStatus="myIndex">

myIndex.index will give you the index. Here myIndex is a LoopTagStatus object.

Hence, you can send that to your javascript method like this:-

<a onclick="getCategoryIndex(${myIndex.index})" href="#">${categoryName}</a>

If you want to denote an actual error in your code, you could raise a RuntimeError exception:

raise RuntimeError, 'Message goes here'

This will print a stacktrace, the type of the exception being raised and the message that you provided. Depending on your users, a stacktrace might be too scary, and the actual message might get lost in the noise. On the other hand, if you die because of an actual error, a stacktrace will give you additional information for debugging.

Another way, simpler.

Add your

build.gradle

file to the root of your project. Close the project. Manually remove *.iml file. Then choose "Import Project...", navigate to your project directory, select the build.gradle file and click OK.

Dynamic variables creation

Pros

• Works for >9 arguments
• Keeps %1, %2, ... %* in tact
• Works for both /arg and -arg style
• No prior knowledge about arguments
• Implementation is separate from main routine

Cons

• Old arguments may leak into consecutive runs, therefore use setlocal for local scoping or write an accompanying :CLEAR-ARGS routine!
• No alias support yet (like --force to -f)
• No empty "" argument support

Usage

Here is an example how the following arguments relate to .bat variables:

>> testargs.bat /b 3 -c /d /e /f /g /h /i /j /k /bar 5 /foo "c:\"

echo %*        | /b 3 -c /d /e /f /g /h /i /j /k /bar 5 /foo "c:\"
echo %ARG_FOO% | c:\
echo %ARG_A%   |
echo %ARG_B%   | 3
echo %ARG_C%   | 1
echo %ARG_D%   | 1

Implementation

@echo off
setlocal

CALL :ARG-PARSER %*

::Print examples
echo: ALL: %*
echo: FOO: %ARG_FOO%
echo: A:   %ARG_A%
echo: B:   %ARG_B%
echo: C:   %ARG_C%
echo: D:   %ARG_D%


::*********************************************************
:: Parse commandline arguments into sane variables

This is not an error, it is a warning from your Microsoft compiler.

Select your project and click "Properties" in the context menu.

In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor

In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.

Before Applying Property box-shadow : none

After Applying Property box-shadow : none

This is the easiest solution and it worked for me

input {
   box-shadow : none;  
}

Maybe your method for adding items into fragment should be public (placed in desired Fragment) and should have parameter the same type as selectedItems ..

That will make it visible from activity, which will have selectedItems array and voila..

p.s. better name it addItemsFromArray(typeOfSelectedItems[] pSelectedItems) cause name addItem() is quite undescriptive

Edit: stackoverflow just suggested similar topic :) Check here for detailed idea implementation.. :)

With Linq To SQL I debugged by logging the context, eg. Context.Log = Console.Out Then scanned the SQL to check for any obvious errors, there were two:

-- @p46: Input Char (Size = -1; Prec = 0; Scale = 0) [some long text value1]
-- @p8: Input Char (Size = -1; Prec = 0; Scale = 0) [some long text value2]

the last one I found by scanning the table schema against the values, the field was nvarchar(20) but the value was 22 chars

-- @p41: Input NVarChar (Size = 4000; Prec = 0; Scale = 0) [1234567890123456789012]

You need to iterate over your ResultSet calling next().

This is an example from java2s.com:

DatabaseMetaData md = conn.getMetaData();
ResultSet rs = md.getTables(null, null, "%", null);
while (rs.next()) {
  System.out.println(rs.getString(3));
}

Column 3 is the TABLE_NAME (see documentation of DatabaseMetaData::getTables).

The FragmentManger's function add and replace can be described as these 1. add means it will add the fragment in the fragment back stack and it will show at given frame you are providing like

getFragmentManager.beginTransaction.add(R.id.contentframe,Fragment1.newInstance(),null)

2.replace means that you are replacing the fragment with another fragment at the given frame

getFragmentManager.beginTransaction.replace(R.id.contentframe,Fragment1.newInstance(),null)

The Main utility between the two is that when you are back stacking the replace will refresh the fragment but add will not refresh previous fragment.

If you're on Android, you can do this:

Uri uri = Uri.parse(url);
String v = uri.getQueryParameter("v");

You need to get hold of the axes themselves. Probably the cleanest way is to change your last row:

lm = sns.lmplot('X','Y',df,col='Z',sharex=False,sharey=False)

Then you can get hold of the axes objects (an array of axes):

axes = lm.axes

After that you can tweak the axes properties

axes[0,0].set_ylim(0,)
axes[0,1].set_ylim(0,)

creates:

I needed something to print things out nicely and separate the bits every n-bit. In other words display the leading zeros and show something like this:

n = 5463
output = 0000 0000 0000 0000 0001 0101 0101 0111

So here's what I wrote:

/**
 * Converts an integer to a 32-bit binary string
 * @param number
 *      The number to convert
 * @param groupSize
 *      The number of bits in a group
 * @return
 *      The 32-bit long bit string
 */
public static String intToString(int number, int groupSize) {
    StringBuilder result = new StringBuilder();

    for(int i = 31; i >= 0 ; i--) {
        int mask = 1 << i;
        result.append((number & mask) != 0 ? "1" : "0");

        if (i % groupSize == 0)
            result.append(" ");
    }
    result.replace(result.length() - 1, result.length(), "");

    return result.toString();
}

Invoke it like this:

public static void main(String[] args) {
    System.out.println(intToString(5463, 4));
}

The problem comes from instinctively believing that DISTINCT is a local pre-modifier for a column.

Hence, you "should" be able to type

XXbadXX SELECT col1, DISTINCT col2 FROM mytable XXbadXX

and have it return unique values for col2. Sadly, no. DISTINCT is actually a global post-modifier for SELECT, that is, as opposed to SELECT ALL (returning all answers) it is SELECT DISTINCT (returning all unique answers). So a single DISTINCT acts on ALL the columns that you give it.

This makes it real hard to use DISTINCT on a single column, while getting the other columns, without doing major extremely ugly backflips.

The correct answer is to use a GROUP BY on the columns that you want to have unique answers: SELECT col1, col2 FROM mytable GROUP BY col2 will give you arbitrary unique col2 rows, with their col1 data as well.

Iteration can be done as below. Complexity = O(n)

public static LLNode mergeSortedListIteration(LLNode nodeA, LLNode nodeB) {
    LLNode mergedNode ;
    LLNode tempNode ;      

    if (nodeA == null) {
        return nodeB;
      } 
      if (nodeB == null) {
        return nodeA;
      }     


    if ( nodeA.getData() < nodeB.getData())
    {
        mergedNode = nodeA;
        nodeA = nodeA.getNext();
    }
    else
    {
        mergedNode = nodeB;
        nodeB = nodeB.getNext();
    }

    tempNode = mergedNode; 

    while (nodeA != null && nodeB != null)
    {           

        if ( nodeA.getData() < nodeB.getData())
        {               
            mergedNode.setNext(nodeA);
            nodeA = nodeA.getNext();
        }
        else
        {
            mergedNode.setNext(nodeB);
            nodeB = nodeB.getNext();                
        }       
        mergedNode = mergedNode.getNext();
    }

    if (nodeA != null)
    {
        mergedNode.setNext(nodeA);
    }

    if (nodeB != null)
    {
        mergedNode.setNext(nodeB);
    }       
    return tempNode;
}

make the checkbox non-focusable, and on list-item click do this, here codevalue is the position.

    Arraylist<Integer> selectedschools=new Arraylist<Integer>();

    lvPickSchool.setOnItemClickListener(new AdapterView.OnItemClickListener() 
  {

   @Override
        public void onItemClick(AdapterView<?> parent, View view, int codevalue, long id)
   {
                      CheckBox cb = (CheckBox) view.findViewById(R.id.cbVisitingStatus);

            cb.setChecked(!cb.isChecked());
            if(cb.isChecked())
            {

                if(!selectedschool.contains(codevaule))
                {
                    selectedschool.add(codevaule);
                }
            }
            else
            {
                if(selectedschool.contains(codevaule))
                {
                    selectedschool.remove(codevaule);
                }
            }
        }
    });

In latest Angular 7/8, you can use the simplest approach:-

import { HttpClient, HttpHeaders, HttpParams } from '@angular/common/http';

getDetails(searchParams) {
    const httpOptions = {
        headers: { 'Content-Type': 'application/json' },
        params: { ...searchParams}
    };
    return this.http.get(this.Url, httpOptions);
}

Maybe you can try pyshmht, sharing memory based hash table extension for Python.

Notice

1. It's not fully tested, just for your reference.

2. It currently lacks lock/sem mechanisms for multiprocessing.

This is a one line solution involving LINQ.

var elements = new String[] { "1", "2", "3" };
Foo(elements.Cast<object>().ToArray())

While the above answer is 100% helpful and correct, I'd like to add the following since only a combination of the above answer and reading through the pandas doc helped me:

2-digit / 4-digit year

It is noteworthy, that in order to parse through a 2-digit year, e.g. '90' rather than '1990', a %y is required instead of a %Y.

Infer the datetime automatically

If parsing with a pre-defined format still doesn't work for you, try using the flag infer_datetime_format=True, for example:

yields_df['Date'] = pd.to_datetime(yields_df['Date'], infer_datetime_format=True)

Be advised that this solution is slower than using a pre-defined format.

If you use the request body in a GET request, you're breaking the REST principle, because your GET request won't be able to be cached, because cache system uses only the URL.

What's worse, your URL can't be bookmarked, because the URL doesn't contain all the information needed to redirect the user to this page.

Use URL or Query parameters instead of request body parameters, e.g.:

/myapp?var1=xxxx&var2=xxxx
/myapp;var1=xxxx/resource;var2=xxxx 

In fact, the HTTP RFC 7231 says that:

A payload within a GET request message has no defined semantics; sending a payload body on a GET request might cause some existing implementations to reject the request.

For more information take a look here.

For all browsers

The following function will perform a lot faster than the option suggested in the accepted answer:

var repeat = function(str, count) {
    var array = [];
    for(var i = 0; i < count;)
        array[i++] = str;
    return array.join('');
}

You'd use it like this :

var repeatedString = repeat("a", 10);

To compare the performance of this function with that of the option proposed in the accepted answer, see this Fiddle and this Fiddle for benchmarks.

For moderns browsers only

In modern browsers, you can now do this using String.prototype.repeat method:

var repeatedString = "a".repeat(10);

Read more about this method on MDN.

This option is even faster. Unfortunately, it doesn't work in any version of Internet explorer. The numbers in the table specify the first browser version that fully supports the method:

Quote from the Python 3 Reference:

The nonlocal statement causes the listed identifiers to refer to previously bound variables in the nearest enclosing scope excluding globals.

As said in the reference, in case of several nested functions only variable in the nearest enclosing function is modified:

def outer():
    def inner():
        def innermost():
            nonlocal x
            x = 3

        x = 2
        innermost()
        if x == 3: print('Inner x has been modified')

    x = 1
    inner()
    if x == 3: print('Outer x has been modified')

x = 0
outer()
if x == 3: print('Global x has been modified')

# Inner x has been modified

The "nearest" variable can be several levels away:

def outer():
    def inner():
        def innermost():
            nonlocal x
            x = 3

        innermost()

    x = 1
    inner()
    if x == 3: print('Outer x has been modified')

x = 0
outer()
if x == 3: print('Global x has been modified')

# Outer x has been modified

But it cannot be a global variable:

def outer():
    def inner():
        def innermost():
            nonlocal x
            x = 3

        innermost()

    inner()

x = 0
outer()
if x == 3: print('Global x has been modified')

# SyntaxError: no binding for nonlocal 'x' found

I just want to add, if you get this error because you are using Cygwin make and auto-generated files, you can fix it with the following sed,

sed -e 's@\\\([^ ]\)@/\1@g' -e 's@[cC]:@/cygdrive/c@' -i filename.d

You may need to add more characters than just space to the escape list in the first substitution but you get the idea. The concept here is that /cygdrive/c is an alias for c: that cygwin's make will recognize.

And may as well throw in

-e 's@^ \+@\t@'

just in case you did start with spaces on accident (although I /think/ this will usually be a "missing separator" error).

Slash is a date delimiter, so that will use the current culture date delimiter.

If you want to hard-code it to always use slash, you can do something like this:

DateTime.ToString("dd'/'MM'/'yyyy")

If you don't want to modify the databound object from some reason (for example you want to show some view in your grid, but you don't want it as a part of the datasource object), you might want to do this:

1.Add column manually:

    DataGridViewColumn c = new DataGridViewColumn();
    DataGridViewCell cell = new DataGridViewTextBoxCell();

    c.CellTemplate = cell;
    c.HeaderText = "added";
    c.Name = "added";
    c.Visible = true;
dgv.Columns.Insert(0, c); 

2.In the DataBindingComplete event do something like this:

foreach (DataGridViewRow row in dgv.Rows)
{if (row.Cells[7].Value.ToString()=="1")
row.Cells[0].Value = "number one"; }

(just a stupid example)

but remember IT HAS to be in the DataBindingComplete, otherwise value will remain blank

maybe this is what u want?

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

for example:

- for (var i = 0; i < 10; ++i) {
  li= array[i]
- }

Solved it as follows,

in CSS

#my{
zoom: 100%;
}

Now, it loads in 100% zoom by default. Tested it by giving 290% zoom and it loaded by that zoom percentage on default, it's upto the user if he wants to change zoom.

Though this is not the best way to do it, there is another effective solution

Check the page code of stack over flow, even they have buttons and they use un ordered lists to solve this problem.

Sample DF:

In [79]: df = pd.DataFrame(np.random.randint(5, 15, (10, 3)), columns=list('abc'))

In [80]: df
Out[80]:
    a   b   c
0   6  11  11
1  14   7   8
2  13   5  11
3  13   7  11
4  13   5   9
5   5  11   9
6   9   8   6
7   5  11  10
8   8  10  14
9   7  14  13

present only those rows where b > 10

In [81]: df[df.b > 10]
Out[81]:
   a   b   c
0  6  11  11
5  5  11   9
7  5  11  10
9  7  14  13

Minimums (for all columns) for the rows satisfying b > 10 condition

In [82]: df[df.b > 10].min()
Out[82]:
a     5
b    11
c     9
dtype: int32

Minimum (for the b column) for the rows satisfying b > 10 condition

In [84]: df.loc[df.b > 10, 'b'].min()
Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

INSERT OR REPLACE is NOT equivalent to "UPSERT".

Say I have the table Employee with the fields id, name, and role:

INSERT OR REPLACE INTO Employee ("id", "name", "role") VALUES (1, "John Foo", "CEO")
INSERT OR REPLACE INTO Employee ("id", "role") VALUES (1, "code monkey")

Boom, you've lost the name of the employee number 1. SQLite has replaced it with a default value.

The expected output of an UPSERT would be to change the role and to keep the name.

If you want to run your scripts, then

mysql -u root -p < yourscript.sql

I would use a macro to record my actions and would then repeat it.

1. Put your cursor on the first letter in name.
2. Hit qq to start recording into the q buffer.
3. Hit i to go into insert mode, type vector_, and then hit Esc to leave insert mode.
4. Now hit 0 to go back to the beginning of the line.
5. Now hit j to go down.
6. Now hit q again to stop recording.

You now have a nice macro.

Type 3@q to execute your macro three times to do the rest of the lines.

sumr is implemented in terms of foldRight:

 final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append) 

foldRight is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

Suppose you wanted to cast a String to a File (yes it does not make any sense), you cannot cast it directly because the File class is not a child and not a parent of the String class (and the compiler complains).

But you could cast your String to Object, because a String is an Object (Object is parent). Then you could cast this object to a File, because a File is an Object.

So all you operations are 'legal' from a typing point of view at compile time, but it does not mean that it will work at runtime !

File f = (File)(Object) "Stupid cast";

The compiler will allow this even if it does not make sense, but it will crash at runtime with this exception:

Exception in thread "main" java.lang.ClassCastException:
    java.lang.String cannot be cast to java.io.File

<h2 id="changeText" class="mainText"> Main Text </h2>

(function() {
    var mainText = $('.mainText').text(),
        altText = 'Alt Text';

    $('#changeText').on('click', function(){
        $(this).toggleClass('altText');
        $('.mainText').text(mainText);
        $('.altText').text(altText);
    });

})();

Funny, I recently had to do this.

function padDigits(number, digits) {
    return Array(Math.max(digits - String(number).length + 1, 0)).join(0) + number;
}

Use like:

padDigits(9, 4);  // "0009"
padDigits(10, 4); // "0010"
padDigits(15000, 4); // "15000"

Not beautiful, but effective.

Use below style modification to remove border for Primefaces radio button

.ui-selectoneradio td, .ui-selectoneradio tr
{
    border-style: none !important
}

There are tons of sample code online as to how to do this.

Here is just one example of how to do this: http://geekswithblogs.net/dotNETvinz/archive/2009/04/30/creating-a-simple-registration-form-in-asp.net.aspx

you define the text boxes between the following tag:

<form id="form1" runat="server"> 

you create your textboxes and define them to runat="server" like so:

<asp:TextBox ID="TxtName" runat="server"></asp:TextBox>

define a button to process your logic like so (notice the onclick):

<asp:Button ID="Button1" runat="server" Text="Save" onclick="Button1_Click" />

in the code behind, you define what you want the server to do if the user clicks on the button by defining a method named

protected void Button1_Click(object sender, EventArgs e)

or you could just double click the button in the design view.

Here is a very quick sample of code to insert into a table in the button click event (codebehind)

protected void Button1_Click(object sender, EventArgs e)
{
   string name = TxtName.Text; // Scrub user data

   string connString = ConfigurationManager.ConnectionStrings["yourconnstringInWebConfig"].ConnectionString;
   SqlConnection conn = null;
   try
   {
          conn = new SqlConnection(connString);
          conn.Open();

          using(SqlCommand cmd = new SqlCommand())
          {
                 cmd.Conn = conn;
                 cmd.CommandType = CommandType.Text;
                 cmd.CommandText = "INSERT INTO dummyTable(name) Values (@var)";
                 cmd.Parameters.AddWithValue("@var", name);
                 int rowsAffected = cmd.ExecuteNonQuery();
                 if(rowsAffected ==1)
                 {
                        //Success notification
                 }
                 else
                 {
                        //Error notification
                 }
          }
   }
   catch(Exception ex)
   {
          //log error 
          //display friendly error to user
   }
   finally
   {
          if(conn!=null)
          {
                 //cleanup connection i.e close 
          }
   }
}

There is solution for you :)

You must run your script after window loaded

if you use jQuery, you can use simple way:

<div id="fb-root"></div>
<script>
    window.fbAsyncInit = function() {
        FB.init({
            appId      : 'your-app-id',
            xfbml      : true,
            status     : true,
            version    : 'v2.5'
        });
    };

    (function(d, s, id){
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) {return;}
        js = d.createElement(s); js.id = id;
        js.src = "//connect.facebook.net/en_US/sdk.js";
        fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
</script>

<script>
$(window).load(function() {
    var comment_callback = function(response) {
        console.log("comment_callback");
        console.log(response);
    }
    FB.Event.subscribe('comment.create', comment_callback);
    FB.Event.subscribe('comment.remove', comment_callback);
});
</script>

I guess there is an alternative way to achieve what you are looking for. I don't say its a complete solution but it served the purpose in my case.

What I did is instead of replacing the fragment I just added target fragment. So basically you will be going to use add() method instead replace().

What else I did. I hide my current fragment and also add it to backstack.

Hence it overlaps new fragment over the current fragment without destroying its view.(check that its onDestroyView() method is not being called. Plus adding it to backstate gives me the advantage of resuming the fragment.

Here is the code :

Fragment fragment=new DestinationFragment();
FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction ft=fragmentManager.beginTransaction();
ft.add(R.id.content_frame, fragment);
ft.hide(SourceFragment.this);
ft.addToBackStack(SourceFragment.class.getName());
ft.commit();

AFAIK System only calls onCreateView() if the view is destroyed or not created. But here we have saved the view by not removing it from memory. So it will not create a new view.

And when you get back from Destination Fragment it will pop the last FragmentTransaction removing top fragment which will make the topmost(SourceFragment's) view to appear over the screen.

COMMENT: As I said it is not a complete solution as it doesn't remove the view of Source fragment and hence occupying more memory than usual. But still, serve the purpose. Also, we are using a totally different mechanism of hiding view instead of replacing it which is non traditional.

So it's not really for how you maintain the state, but for how you maintain the view.

img = cv2.imread("/x2.jpeg")

image = cv2.resize(img, (1800, 1800))

alpha=1.5
beta=20

new_image=cv2.addWeighted(image,alpha,np.zeros(image.shape, image.dtype),0,beta)

cv2.imshow("new",new_image)
cv2.waitKey(0)
cv2.destroyAllWindows()

Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like

INSERT INTO HISTORICAL_CAR_STATS (
    HISTORICAL_CAR_STATS_ID, 
    YEAR,
    MONTH, 
    MAKE,
    MODEL,
    REGION,
    AVG_MSRP,
    CNT) 
SELECT MY_SEQ.nextval,
       year,
       month,
       make,
       model,
       region,
       avg_msrp,
       cnt
  FROM (SELECT '2010' year,
               '12' month,
               'ALL' make,
               'ALL' model,
               REGION,
               sum(AVG_MSRP*COUNT)/sum(COUNT) avg_msrp,
               sum(cnt) cnt
          FROM HISTORICAL_CAR_STATS
         WHERE YEAR = '2010' 
           AND MONTH = '12'
           AND MAKE != 'ALL' 
         GROUP BY REGION)

This can be done in two ways.

JLabel Horizontal Alignment

You can use the JLabel constructor:

JLabel(String text, int horizontalAlignment) 

To align to the right:

JLabel label = new JLabel("Telephone", SwingConstants.RIGHT);

JLabel also has setHorizontalAlignment:

label.setHorizontalAlignment(SwingConstants.RIGHT);

This assumes the component takes up the whole width in the container.

Using Layout

A different approach is to use the layout to actually align the component to the right, whilst ensuring they do not take the whole width. Here is an example with BoxLayout:

    Box box = Box.createVerticalBox();
    JLabel label1 = new JLabel("test1, the beginning");
    label1.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label1);

    JLabel label2 = new JLabel("test2, some more");
    label2.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label2);

    JLabel label3 = new JLabel("test3");
    label3.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label3);


    add(box);

Here is a comparison with np.einsum to show how the indices are projected

np.allclose(np.einsum('ijk,ijk->ijk', a,b), a*b)        # True 
np.allclose(np.einsum('ijk,ikl->ijl', a,b), a@b)        # True
np.allclose(np.einsum('ijk,lkm->ijlm',a,b), a.dot(b))   # True

Install Inspect-it

pip3 install inspect-it --user

Code

import inspect;print(*['\n\x1b[0;36;1m| \x1b[0;32;1m{:25}\x1b[0;36;1m| \x1b[0;35;1m{}'.format(str(x.function), x.filename+'\x1b[0;31;1m:'+str(x.lineno)+'\x1b[0m') for x in inspect.stack()])

you can Make a snippet of this line

it will show you a list of the function call stack with a filename and line number

list from start to where you put this line

Assuming the thread code is out of your control:

From the Java documentation mentioned above:

What if a thread doesn't respond to Thread.interrupt?

In some cases, you can use application specific tricks. For example, if a thread is waiting on a known socket, you can close the socket to cause the thread to return immediately. Unfortunately, there really isn't any technique that works in general. It should be noted that in all situations where a waiting thread doesn't respond to Thread.interrupt, it wouldn't respond to Thread.stop either. Such cases include deliberate denial-of-service attacks, and I/O operations for which thread.stop and thread.interrupt do not work properly.

Bottom Line:

Make sure all threads can be interrupted, or else you need specific knowledge of the thread - like having a flag to set. Maybe you can require that the task be given to you along with the code needed to stop it - define an interface with a stop() method. You can also warn when you failed to stop a task.

There's a tutorial on Zend's devzone on generating pdf from php (part 1, part 2) without any external libraries. I never implemented this sort of solution, but since it's all php, you might find it more flexible to implement and debug.

Here is an alternative way to get an object's property value:

write-host $(get-something).SomeProp

Your confusion stems from the fact that declared properties are not (necessarily named the same as) (instance) variables.

The expresion

indexPath.row

is equivalent to

[indexPath row]

and the assignment

delegate.myData = [myData objectAtIndex:indexPath.row];

is equivalent to

[delegate setMyData:[myData objectAtIndex:[indexPath row]]];

assuming standard naming for synthesised properties.

Furthermore, delegate is probably declared as being of type id<SomeProtocol>, i.e., the compiler hasn’t been able to provide actual type information for delegate at that point, and the debugger is relying on information provided at compile-time. Since id is a generic type, there’s no compile-time information about the instance variables in delegate.

Those are the reasons why you don’t see myData or row as variables.

If you want to inspect the result of sending -row or -myData, you can use commands p or po:

p (NSInteger)[indexPath row]
po [delegate myData]

or use the expressions window (for instance, if you know your delegate is of actual type MyClass *, you can add an expression (MyClass *)delegate, or right-click delegate, choose View Value as… and type the actual type of delegate (e.g. MyClass *).

That being said, I agree that the debugger could be more helpful:

• There could be an option to tell the debugger window to use run-time type information instead of compile-time information. It'd slow down the debugger, granted, but would provide useful information;

• Declared properties could be shown up in a group called properties and allow for (optional) inspection directly in the debugger window. This would also slow down the debugger because of the need to send a message/execute a method in order to get information, but would provide useful information, too.

To get the job done, use

<table cellspacing=12>

If you’d rather “be right” than get things done, you can instead use the CSS property border-spacing, which is supported by some browsers.

Adding a small variation to estani's excellent answer

Local to ISO 8601 with TimeZone and no microsecond info (Python 3):

import datetime, time

utc_offset_sec = time.altzone if time.localtime().tm_isdst else time.timezone
utc_offset = datetime.timedelta(seconds=-utc_offset_sec)
datetime.datetime.now().replace(microsecond=0, tzinfo=datetime.timezone(offset=utc_offset)).isoformat()

Sample Output:

'2019-11-06T12:12:06-08:00'

Tested that this output can be parsed by both Javascript Date and C# DateTime/DateTimeOffset

If you want to generate your email bodies in razor, you can use Mailzory. Also, you can download the nuget package from here.

// template path
var viewPath = Path.Combine("Views/Emails", "hello.cshtml");
// read the content of template and pass it to the Email constructor
var template = File.ReadAllText(viewPath);

var email = new Email(template);

// set ViewBag properties
email.ViewBag.Name = "Johnny";
email.ViewBag.Content = "Mailzory Is Funny";

// send email
var task = email.SendAsync("[email protected]", "subject");
task.Wait()

After searching a bit about the method to open the existing sheet in xlxs, i discovered

existingWorksheet = wb.get_worksheet_by_name('Your Worksheet name goes here...')
existingWorksheet.write_row(0,0,'xyz')

You can now append/write any data to the open worksheet. I hope it helps. Thanks

If you click on the empty spot on the report away from any table and then look in properties, one of the Misc fields is called Language which allows you to pick which Language you would like to set, which after doing so can play around with this

To add to the great asnwer by @Krunal https://stackoverflow.com/a/49552326/4697535

In case you are using a UINavigationController, the preferredStatusBarStyle will have no effect on the UIViewController.

Xcode 10 and Swift 4.

Set a custom UINavigationController

Example:

class LightNavigationController: UINavigationController {

   open override var preferredStatusBarStyle: UIStatusBarStyle {
       return .lightContent
   }
}

Use an extension for an app level solution:

extension UINavigationController {

  open override var preferredStatusBarStyle: UIStatusBarStyle {
      guard let index = tabBarController?.selectedIndex else { return .default }
      switch index {
      case 0, 1, 2: return .lightContent // set lightContent for tabs 0-2
      default: return .default // set dark for tab 3
      }
  }
}

I created this solution from the above suggestions mixed with microsofts solution of for iterating through a collection.

Public Function InCollection(col As Collection, Optional vItem, Optional vKey) As Boolean
On Error Resume Next

Dim vColItem As Variant

InCollection = False

If Not IsMissing(vKey) Then
    col.item vKey

    '5 if not in collection, it is 91 if no collection exists
    If Err.Number <> 5 And Err.Number <> 91 Then
        InCollection = True
    End If
ElseIf Not IsMissing(vItem) Then
    For Each vColItem In col
        If vColItem = vItem Then
            InCollection = True
            GoTo Exit_Proc
        End If
    Next vColItem
End If

Exit_Proc:
Exit Function
Err_Handle:
Resume Exit_Proc
End Function

It is to do with file permissions and it happens on systems that have the suphp(usually cpanel/whost servers) installed.

Removing the write permission from anyone else but the owner(644|600) for the php files will fix the issue. That is how i got it fixed.

I hope this helps.

Consider using subtree instead of submodules, it will make your repo users life much easier. You may find more detailed guide in Pro Git book.

Shorter explanation:

In C++, struct and class were just two sides of the same coin. The only real difference is that one was public by default and the other was private.

In .NET, there is a much greater difference between a struct and a class. The main thing is that struct provides value-type semantics, while class provides reference-type semantics. When you start thinking about the implications of this change, other changes start to make more sense as well, including the constructor behavior you describe.

Here is an another solution. Using sys's default views are so slow (approx 10s in my situation). This is much faster than that (approx. 0.5s).

SELECT
    CONST.NAME AS CONSTRAINT_NAME,
    RCONST.NAME AS REF_CONSTRAINT_NAME,

    OBJ.NAME AS TABLE_NAME,
    COALESCE(ACOL.NAME, COL.NAME) AS COLUMN_NAME,
    CCOL.POS# AS POSITION,

    ROBJ.NAME AS REF_TABLE_NAME,
    COALESCE(RACOL.NAME, RCOL.NAME) AS REF_COLUMN_NAME,
    RCCOL.POS# AS REF_POSITION
FROM SYS.CON$ CONST
INNER JOIN SYS.CDEF$ CDEF ON CDEF.CON# = CONST.CON#
INNER JOIN SYS.CCOL$ CCOL ON CCOL.CON# = CONST.CON#
INNER JOIN SYS.COL$ COL  ON (CCOL.OBJ# = COL.OBJ#) AND (CCOL.INTCOL# = COL.INTCOL#)
INNER JOIN SYS.OBJ$ OBJ ON CCOL.OBJ# = OBJ.OBJ#
LEFT JOIN SYS.ATTRCOL$ ACOL ON (CCOL.OBJ# = ACOL.OBJ#) AND (CCOL.INTCOL# = ACOL.INTCOL#)

INNER JOIN SYS.CON$ RCONST ON RCONST.CON# = CDEF.RCON#
INNER JOIN SYS.CCOL$ RCCOL ON RCCOL.CON# = RCONST.CON#
INNER JOIN SYS.COL$ RCOL  ON (RCCOL.OBJ# = RCOL.OBJ#) AND (RCCOL.INTCOL# = RCOL.INTCOL#)
INNER JOIN SYS.OBJ$ ROBJ ON RCCOL.OBJ# = ROBJ.OBJ#
LEFT JOIN SYS.ATTRCOL$ RACOL  ON (RCCOL.OBJ# = RACOL.OBJ#) AND (RCCOL.INTCOL# = RACOL.INTCOL#)

  AND RCONST.OWNER# = userenv('SCHEMAID')
  AND CDEF.TYPE# = 4  /* 'R' Referential/Foreign Key */;

I got the error using TFS, my AssemblyInfo wasn't mapped in the branch I was working on.

Yep, that would be the enumerate function! Or more to the point, you need to do:

list(enumerate([3,7,19]))

[(0, 3), (1, 7), (2, 19)]

Your best bet is to review the Java Swing tutorials, specifically the tutorial on Buttons.

The short code snippet is:

jBtnDrawCircle.addActionListener( /*class that implements ActionListener*/ );

I know I'm late to answer this, but I read most of the answers and while many were great, only djn actually explained why you were getting this 500 Internal Server Error.

While his explanation was 100% correct, this is a perfect example of why you should always wrap those in an <IfModule>. While this won't fix the actual problem of not being able to set those flags in your .htaccess, it will at least prevent the 500 error.

<IfModule mod_php5.c>
    # put all of your php_flags here, for example:
    php_flag magic_quotes_gpc off
</IfModule>

Or for older versions it would be <IfModule mod_php.c> etc.

I try to make a habit out of always doing this so as to avoid any such 500 errors. After that, just apply what Peter Bailey said.

I have fumbled around sometime to reach these considerations:

1- If my application access the database, why the test should not? What if there is something wrong with data access? The tests must know it beforehand and alert myself about the problem.

2- The Repository Pattern is somewhat hard and time consuming.

So I came up with this approach, that I don't think is the best, but fulfilled my expectations:

Use TransactionScope in the tests methods to avoid changes in the database.

To do it it's necessary:

1- Install the EntityFramework into the Test Project. 2- Put the connection string into the app.config file of Test Project. 3- Reference the dll System.Transactions in Test Project.

The unique side effect is that identity seed will increment when trying to insert, even when the transaction is aborted. But since the tests are made against a development database, this should be no problem.

Sample code:

[TestClass]
public class NameValueTest
{
    [TestMethod]
    public void Edit()
    {
        NameValueController controller = new NameValueController();

        using(var ts = new TransactionScope()) {
            Assert.IsNotNull(controller.Edit(new Models.NameValue()
            {
                NameValueId = 1,
                name1 = "1",
                name2 = "2",
                name3 = "3",
                name4 = "4"
            }));

            //no complete, automatically abort
            //ts.Complete();
        }
    }

    [TestMethod]
    public void Create()
    {
        NameValueController controller = new NameValueController();

        using (var ts = new TransactionScope())
        {
            Assert.IsNotNull(controller.Create(new Models.NameValue()
            {
                name1 = "1",
                name2 = "2",
                name3 = "3",
                name4 = "4"
            }));

            //no complete, automatically abort
            //ts.Complete();
        }
    }
}

If the database in question is local, the following is probably the most robust way to export a query result to a CSV file (that is, giving you the most control).

1. Copy the query.
2. In Object Explorer right-click on the database in question.
3. Select "Tasks" >> "Export Data..."
4. Configure your datasource, and click "Next".
5. Choose "Flat File" or "Microsoft Excel" as destination.
6. Specify a file path.
7. If working with a flat file, configure as desired. If working with Microsoft Excel, select "Excel 2007" (previous versions have a row limit at 64k)
8. Select "Write a query to specify the data to transfer"
9. Paste query from Step 1.
10. Click next >> review mappings >> click next >> select "run immediately" >> click "finish" twice.

After going through this process exhaustively, I found the following to be the best option

PowerShell Script

$dbname = "**YOUR_DB_NAME_WITHOUT_STARS**"
$AttachmentPath = "c:\\export.csv"
$QueryFmt= @"
**YOUR_QUERY_WITHOUT_STARS**
"@

Invoke-Sqlcmd   -ServerInstance **SERVER_NAME_WITHOUT_STARS** -Database  $dbname -Query $QueryFmt | Export-CSV $AttachmentPath -NoTypeInformation

Run PowerShell as Admin

& "c:\path_to_your_ps1_file.ps1"

A Record lets you create a new type from a Union. The values in the Union are used as attributes of the new type.

For example, say I have a Union like this:

type CatNames = "miffy" | "boris" | "mordred";

Now I want to create an object that contains information about all the cats, I can create a new type using the values in the CatName Union as keys.

type CatList = Record<CatNames, {age: number}>

If I want to satisfy this CatList, I must create an object like this:

const cats:CatList = {
  miffy: { age:99 },
  boris: { age:16 },
  mordred: { age:600 }
}

You get very strong type safety:

• If I forget a cat, I get an error.
• If I add a cat that's not allowed, I get an error.
• If I later change CatNames, I get an error. This is especially useful because CatNames is likely imported from another file, and likely used in many places.

Real-world React example.

I used this recently to create a Status component. The component would receive a status prop, and then render an icon. I've simplified the code quite a lot here for illustrative purposes

I had a union like this:

type Statuses = "failed" | "complete";

I used this to create an object like this:

const icons: Record<
  Statuses,
  { iconType: IconTypes; iconColor: IconColors }
> = {
  failed: {
    iconType: "warning",
    iconColor: "red"
  },
  complete: {
    iconType: "check",
    iconColor: "green"
  };

I could then render by destructuring an element from the object into props, like so:

const Status = ({status}) => <Icon {...icons[status]} />

If the Statuses union is later extended or changed, I know my Status component will fail to compile and I'll get an error that I can fix immediately. This allows me to add additional error states to the app.

Note that the actual app had dozens of error states that were referenced in multiple places, so this type safety was extremely useful.

Try this maybe :

Bootply : http://www.bootply.com/106527

Js :

$('input').on('click', function(){
  var valeur = 0;
  $('input:checked').each(function(){
       if ( $(this).attr('value') > valeur )
       {
           valeur =  $(this).attr('value');

From command prompt as admin run:

netsh interface ip delete destinationcache

Works on Win7.

You can try this-

mysql> select @@datadir;

PS- It works on every platform.

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

Problem: The problem is to get the second largest array element.

Observation: Second largest number is defined as the number that has the minimum difference when subtracted from the maximum element in the array.

Solution: This is a two pass solution. First pass is to find the maximum number. Second pass is to find the element that has minimum difference with the maximum element as compared to other array elements. Example: In the array [2, 3, 6, 6, 5] maximum = 6 and second maximum = 5 , since it has the minimum difference to the maximum element 6 - 5 = 1 the solution for second largest = 5

function printSecondMax(myArray) {
  var x, max = myArray[0];
  // Find maximum element 
  for(x in myArray){
     if(max < myArray[x]){
        max = myArray[x];
     }
  }
  var secondMax = myArray[0], diff = max - secondMax;
  // Find second max, an element that has min diff with the max
  for(x in myArray){
    if(diff != 0 && (max - myArray[x]) != 0 && diff > (max - myArray[x])){
        secondMax = myArray[x];
        diff = max - secondMax;
    }
  }
  console.log(secondMax);
}

Complexity : O(n), This is the simplest way to do this.

For finding maximum element even more efficiently one can look into max heap, a call to max-heapify will take O(log n) time to find the max and then pop-ing the top element gives maximum. To get the second maximum, max-heapify after pop-ing the top and keep pop-ing till you get a number that is less than maximum. That will be the second maximum. This solution has O(n log n) complexity.

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

There's a better alternative to trusting all certificates: Create a TrustStore that specifically trusts a given certificate and use this to create a SSLContext from which to get the SSLSocketFactory to set on the HttpsURLConnection. Here's the complete code:

File crtFile = new File("server.crt");
Certificate certificate = CertificateFactory.getInstance("X.509").generateCertificate(new FileInputStream(crtFile));

KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(null, null);
keyStore.setCertificateEntry("server", certificate);

TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(keyStore);

SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustManagerFactory.getTrustManagers(), null);

HttpsURLConnection connection = (HttpsURLConnection) new URL(url).openConnection();
connection.setSSLSocketFactory(sslContext.getSocketFactory());

You can alternatively load the KeyStore directly from a file or retrieve the X.509 Certificate from any trusted source.

Note that with this code, the certificates in cacerts will not be used. This particular HttpsURLConnection will only trust this specific certificate.

The correct format for passing variables in a GET request is

?variable1=value1&variable2=value2&variable3=value3...
                 ^ ---notice &--- ^

But essentially, you have the right idea.

Run this command in your Mac Terminal app

git config --global core.editor "/Applications/Visual\ Studio\ Code.app/Contents/Resources/app/bin/code"

They don't get submitted, because that's what it says in the W3C specification.

17.13.2 Successful controls

A successful control is "valid" for submission. [snip]

• Controls that are disabled cannot be successful.

In other words, the specification says that controls that are disabled are considered invalid and should not be submitted.

static value may exists into a function and can be used in different forms and can have different value in the program. Also during program after increment of decrement their value may change but const in constant during the whole program.

I did it this way: Just add the event to any control, set the control's tag, and add a conditional to handle the tooltip for the appropriate control/tag.

private void Info_MouseHover(object sender, EventArgs e)
{
    Control senderObject = sender as Control;
    string hoveredControl = senderObject.Tag.ToString();

    // only instantiate a tooltip if the control's tag contains data
    if (hoveredControl != "")
    {
        ToolTip info = new ToolTip
        {
            AutomaticDelay = 500
        };

        string tooltipMessage = string.Empty;

        // add all conditionals here to modify message based on the tag 
        // of the hovered control
        if (hoveredControl == "save button")
        {
            tooltipMessage = "This button will save stuff.";
        }

        info.SetToolTip(senderObject, tooltipMessage);
    }
}

No, it isn't valid HTML5 according to the HTML5 Spec Document from W3C:

Content model: Transparent, but there must be no interactive content descendant.

The a element may be wrapped around entire paragraphs, lists, tables, and so forth, even entire sections, so long as there is no interactive content within (e.g. buttons or other links).

In other words, you can nest any elements inside an <a> except the following:

• <a>

• <audio> (if the controls attribute is present)

• <button>

• <details>

• <embed>

• <iframe>

• <img> (if the usemap attribute is present)

• <input> (if the type attribute is not in the hidden state)

• <keygen>

• <label>

• <menu> (if the type attribute is in the toolbar state)

• <object> (if the usemap attribute is present)

• <select>

• <textarea>

• <video> (if the controls attribute is present)

If you are trying to have a button that links to somewhere, wrap that button inside a <form> tag as such:

<form style="display: inline" action="http://example.com/" method="get">
  <button>Visit Website</button>
</form>

However, if your <button> tag is styled using CSS and doesn't look like the system's widget... Do yourself a favor, create a new class for your <a> tag and style it the same way.

When you have replace: true you get the following piece of DOM:

<div ng-controller="Ctrl" class="ng-scope">
    <div class="ng-binding">hello</div>
</div>

whereas, with replace: false you get this:

<div ng-controller="Ctrl" class="ng-scope">
    <my-dir>
        <div class="ng-binding">hello</div>
    </my-dir>
</div>

So the replace property in directives refer to whether the element to which the directive is being applied (<my-dir> in that case) should remain (replace: false) and the directive's template should be appended as its child,

OR

the element to which the directive is being applied should be replaced (replace: true) by the directive's template.

In both cases the element's (to which the directive is being applied) children will be lost. If you wanted to perserve the element's original content/children you would have to translude it. The following directive would do it:

.directive('myDir', function() {
    return {
        restrict: 'E',
        replace: false,
        transclude: true,
        template: '<div>{{title}}<div ng-transclude></div></div>'
    };
});

In that case if in the directive's template you have an element (or elements) with attribute ng-transclude, its content will be replaced by the element's (to which the directive is being applied) original content.

See example of translusion http://plnkr.co/edit/2DJQydBjgwj9vExLn3Ik?p=preview

See this to read more about translusion.

Now you can make use of reduce function and get the sum.

const object1 = { 'a': 1 , 'b': 2 , 'c':3 }_x000D_
_x000D_
console.log(Object.values(object1).reduce((a, b) => a + b, 0));

EntityFramework 6 has made this a bit easier with .RemoveRange().

Example:

db.People.RemoveRange(db.People.Where(x => x.State == "CA"));
db.SaveChanges();

You can pass you session variables from your php script to JQUERY using JSON such as

JS:

jQuery("#rowed2").jqGrid({
    url:'yourphp.php?q=3', 
    datatype: "json", 
    colNames:['Actions'], 
    colModel:[{
                name:'Actions',
                index:'Actions', 
                width:155,
                sortable:false
              }], 
    rowNum:30, 
    rowList:[50,100,150,200,300,400,500,600], 
    pager: '#prowed2', 
    sortname: 'id',
    height: 660,        
    viewrecords: true, 
    sortorder: 'desc',
    gridview:true,
    editurl: 'yourphp.php', 
    caption: 'Caption', 
    gridComplete: function() { 
        var ids = jQuery("#rowed2").jqGrid('getDataIDs'); 
        for (var i = 0; i < ids.length; i++) { 
            var cl = ids[i]; 
            be = "<input style='height:22px;width:50px;' `enter code here` type='button' value='Edit' onclick=\"jQuery('#rowed2').editRow('"+cl+"');\" />"; 
            se = "<input style='height:22px;width:50px;' type='button' value='Save' onclick=\"jQuery('#rowed2').saveRow('"+cl+"');\" />"; 
            ce = "<input style='height:22px;width:50px;' type='button' value='Cancel' onclick=\"jQuery('#rowed2').restoreRow('"+cl+"');\" />"; 
            jQuery("#rowed2").jqGrid('setRowData', ids[i], {Actions:be+se+ce}); 
        } 
    }
}); 

PHP

// start your session
session_start();

// get session from database or create you own
$session_username = $_SESSION['John'];
$session_email = $_SESSION['[email protected]'];

$response = new stdClass();
$response->session_username = $session_username;
$response->session_email = $session_email;

$i = 0;
while ($row = mysqli_fetch_array($result)) { 
    $response->rows[$i]['id'] = $row['ID']; 
    $response->rows[$i]['cell'] = array("", $row['rowvariable1'], $row['rowvariable2']); 
    $i++; 
} 

echo json_encode($response);
// this response (which contains your Session variables) is sent back to your JQUERY 

Very easy, just use the SQLCMD-syntax.

Remember to enable SQLCMD-mode in the SSMS, look under Query -> SQLCMD Mode

Try execute:

!!DIR
!!:GO

or maybe:
!!DIR "c:/temp"
!!:GO
