For the server-side solution (which your question was originally ambiguous about), this page at sun lists one way to specify a JRE. Specifically,

<OBJECT 
  classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
  width="200" height="200">
  <PARAM name="code" value="Applet1.class">
</OBJECT>

The classid attribute identifies which version of Java Plug-in to use.

Following is an alternative form of the classid attribute:

classid="clsid:CAFEEFAC-xxxx-yyyy-zzzz-ABCDEFFEDCBA"

In this form, "xxxx", "yyyy", and "zzzz" are four-digit numbers that identify the specific version of Java Plug-in to be used.

For example, to use Java Plug-in version 1.5.0, you specify:

classid="clsid:CAFEEFAC-0015-0000-0000-ABCDEFFEDCBA"

I spend a hour finding out what was wrong.. But Clean Project did the trick.

Build -> Clean All

The accepted solution is probably also working.. but this was enough for me.

// include jquery.js
//javascript function

            function(result)
            {

            }
);
function CallServerFunction(StrPriUrl,ObjPriData,CallBackFunction)

    $.ajax({

            alert(result.responseText);

        },
        async: true
    });

Could you have multiple local databases? Check your database.yml and make sure you are hitting the pg db that you want. Use rails console to confirm.

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

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

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

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

I think that mergetool.meld.path should point directly to the meld executable. Thus, the command you want is:

git config --global mergetool.meld.path c:/Progra~2/meld/bin/meld

Swift 3:

let alert = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.default, handler: nil))
alert.addTextField(configurationHandler: {(textField: UITextField!) in
     textField.placeholder = "Enter text:"
})

self.present(alert, animated: true, completion: nil)

Assume you were:

1. Reading a network file and got disconnected.
2. Reading a local file that was no longer available.
3. Using some stream to read data and some other process closed the stream.
4. Trying to read/write a file, but don't have permission.
5. Trying to write to a file, but disk space was no longer available.

There are many more examples, but these are the most common, in my experience.

You can access the first element adding the following code to the highlight function

$(this).find(".selected td:first").html()

Working Code:JSFIDDLE

This requires a series of subqueries to rank the values, limit them, then perform the sum while grouping

@Rnk:=0;
@N:=2;
select
  c.id,
  sum(c.val)
from (
select
  b.id,
  b.bal
from (
select   
  if(@last_id=id,@Rnk+1,1) as Rnk,
  a.id,
  a.val,
  @last_id=id,
from (   
select 
  id,
  val 
from list
order by id,val desc) as a) as b
where b.rnk < @N) as c
group by c.id;

Just install the updated versions of all of them.

apt-get install -y gnupg2 gnupg gnupg1

How are you converting the submitted names to "a simple .txt list"? During that step, can you instead convert them into a simple HTML list or table? Then you could wrap that in a standard header which includes any styling you want.

I had problems using pdftk with the cat parameter had a better success with output.

The following command worked for me:

pdftk file_1.pdf file_1.pdf file_1.pdf file_1.pdf cat output.pdf

Using cat produced the following error:

Error: Unexpected text in page range end, here: 
    output.pdf
    Exiting.
    Acceptable keywords, for example: "even" or "odd".
    To rotate pages, use: "north" "south" "east"
        "west" "left" "right" or "down"
Errors encountered.  No output created.
Done.  Input errors, so no output created.

I created a 172mb PDF is no time at all.

You can't cast an object to a Double if the object is not a Double.

Check out the API.

particularly note

valueOf(double d);

and

valueOf(String s);

Those methods give you a way of getting a Double instance from a String or double primitive. (Also not the constructors; read the documentation to see how they work) The object you are trying to convert naturally has to give you something that can be transformed into a double.

Finally, keep in mind that Double instances are immutable -- once created you can't change them.

The only thing missing hidden from Rob W's excellent answer is how to communicate between the injected page script and the content script.

On the receiving side (either your content script or the injected page script) add an event listener:

document.addEventListener('yourCustomEvent', function (e) {
  var data = e.detail;
  console.log('received', data);
});

On the initiator side (content script or injected page script) send the event:

var data = {
  allowedTypes: 'those supported by structured cloning, see the list below',
  inShort: 'no DOM elements or classes/functions',
};

document.dispatchEvent(new CustomEvent('yourCustomEvent', { detail: data }));

Notes:

• DOM messaging uses structured cloning algorithm, which can transfer only some types of data in addition to primitive values. It can't send class instances or functions or DOM elements.

• In Firefox, to send an object (i.e. not a primitive value) from the content script to the page context you have to explicitly clone it into the target using cloneInto (a built-in function), otherwise it'll fail with a security violation error.

  document.dispatchEvent(new CustomEvent('yourCustomEvent', {
    detail: cloneInto(data, document.defaultView),
  }));
  

For me upgrading gradle version and plugin to the latest version did the trick.

Well you can use below command to export,

mysqldump --databases --user=root --password your_db_name > export_into_db.sql

and the generated file will be available in the same directory where you had ran this command.

Now login to mysql using command,

mysql -u[username] -p

then use "source" command with the file path.

Try it -

package com;

import android.content.Context;
import android.content.res.TypedArray;
import android.util.AttributeSet;
import android.view.View;
import android.widget.ImageView;



public class CheckBoxImageView extends ImageView implements View.OnClickListener {
    boolean checked;
    int defImageRes;
    int checkedImageRes;
    OnCheckedChangeListener onCheckedChangeListener;

    public CheckBoxImageView(Context context, AttributeSet attr, int defStyle) {
        super(context, attr, defStyle);
        init(attr, defStyle);
    }

    public CheckBoxImageView(Context context, AttributeSet attr) {
        super(context, attr);
        init(attr, -1);
    }

    public CheckBoxImageView(Context context) {
        super(context);
    }

    public boolean isChecked() {
        return checked;
    }

    public void setChecked(boolean checked) {
        this.checked = checked;
        setImageResource(checked ? checkedImageRes : defImageRes);
    }

    private void init(AttributeSet attributeSet, int defStyle) {
        TypedArray a = null;
        if (defStyle != -1)
            a = getContext().obtainStyledAttributes(attributeSet, R.styleable.CheckBoxImageView, defStyle, 0);
        else
            a = getContext().obtainStyledAttributes(attributeSet, R.styleable.CheckBoxImageView);
        defImageRes = a.getResourceId(0, 0);
        checkedImageRes = a.getResourceId(1, 0);
        checked = a.getBoolean(2, false);
        a.recycle();
        setImageResource(checked ? checkedImageRes : defImageRes);
        setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        checked = !checked;
        setImageResource(checked ? checkedImageRes : defImageRes);
        onCheckedChangeListener.onCheckedChanged(this, checked);
    }

    public void setOnCheckedChangeListener(OnCheckedChangeListener onCheckedChangeListener) {
        this.onCheckedChangeListener = onCheckedChangeListener;
    }

    public static interface OnCheckedChangeListener {
        void onCheckedChanged(View buttonView, boolean isChecked);
    }
}

Add this attrib -

<declare-styleable name="CheckBoxImageView">
        <attr name="default_img" format="integer"/>
        <attr name="checked_img" format="integer"/>
        <attr name="checked" format="boolean"/>
</declare-styleable>

Use like -

 <com.adonta.ziva.consumer.wrapper.CheckBoxImageView
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/checkBox"
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:clickable="true"
        android:padding="5dp"
        app:checked_img="@drawable/check_box_checked"
        app:default_img="@drawable/check_box" />

It will fix all your porblems.

Note if you have so many tabs open that Google Chrome is only showing the favicons then Google Chrome won't show the favicon for the selected tab, so if you keep reloading the tab with your page loaded in order to see your new favicon you will only see the text of your page's title.

You will need to reload your page, and then select a different tab in order to see your favicon.

Converting your lists to sets will tell you that they contain the same elements. But this method cannot confirm that they contain the same number of all elements. For example, your method will fail in this case:

L1 = [1,2,2,3]
L2 = [1,2,3,3]

You are likely better off sorting the two lists and comparing them:

def checkEqual(L1, L2):
    if sorted(L1) == sorted(L2):
        print "the two lists are the same"
        return True
    else:
        print "the two lists are not the same"
        return False

Note that this does not alter the structure/contents of the two lists. Rather, the sorting creates two new lists

function Index($index) {
    $Count = count($YOUR_ARRAY);
    if ($index <= $Count) {
        $Keys = array_keys($YOUR_ARRAY);
        $Value = array_values($YOUR_ARRAY);
        return $Keys[$index] . ' = ' . $Value[$index];
    } else {
        return "Out of the ring";
    }
}

echo 'Index : ' . Index(0);

Replace the ( $YOUR_ARRAY )

Start by turning the text into a list of lists. That will take care of the parsing part:

lol = list(csv.reader(open('text.txt', 'rb'), delimiter='\t'))

The rest can be done with indexed lookups:

d = dict()
key = lol[6][0]      # cell A7
value = lol[6][3]    # cell D7
d[key] = value       # add the entry to the dictionary
 ...

This can be done with something like this:

# foo.py
class Foo:
    def method_1():
        results = uses_some_other_method()


# testing.py
from mock import patch

@patch('Foo.uses_some_other_method', return_value="specific_value"):
def test_some_other_method(mock_some_other_method):
    foo = Foo()
    the_value = foo.method_1()
    assert the_value == "specific_value"

Here's a source that you can read: Patching in the wrong place

In npm v6+ npm uninstall <package_name> removes it both in folder node_modules and file package.json.

If you want to use the same library folder for several projects, you can reference it in gradle to an external location like this:

settings.gradle:

include 'app', ':volley'
project(':volley').projectDir = new File('../libraries/volley')

in your app build.gradle

dependencies {
    ...
    compile project(':volley')
...}

For what it is worth, depending on the browser, jQuery-based AJAX calls will call your success callback with a HTTP status code of 0. We've found a status code of "0" usually means the user navigated to a different page before the AJAX call completed.

Not the same technology stack as you are using, but hopefully useful to somebody.

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

My answer was inspired by vijay's answer, but is a shorter, more general solution that I thought I'd share for anyone it might help.

(function () { 
    var minutes = true; // change to false if you'd rather use seconds
    var interval = minutes ? 60000 : 1000; 
    var IDLE_TIMEOUT = 3; // 3 minutes in this example
    var idleCounter = 0;

    document.onmousemove = document.onkeypress = function () {
        idleCounter = 0;
    };

    window.setInterval(function () {
        if (++idleCounter >= IDLE_TIMEOUT) {
            window.location.reload(); // or whatever you want to do
        }
    }, interval);
}());

As it currently stands, this code will execute immediately and reload your current page after 3 minutes of no mouse movement or key presses.

This utilizes plain vanilla JavaScript and an immediately-invoked function expression to handle idle timeouts in a clean and self-contained manner.

In my case I had to do this:

for index, user in enumerate(users):
    table_body.append([])
    table_body[index].append(user.user.id)
    table_body[index].append(user.user.username)

Output:

[[1, 'john'], [2, 'bill']]

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)
    for (var name in result[i]) {
        console.log("Item name: "+name);
        console.log("Source: "+result[i][name].sourceUuid);
        console.log("Target: "+result[i][name].targetUuid);
    }

If you want to set null value using update query set column value to NULL (without quotes) update tablename set columnname = NULL

However, if you are directly editing field value inside mysql workbench then use (Esc + del) keystroke to insert null value into selected column

I using Xcode 6+ and I just do:

• Copy all files in project folders to new Folders (with new name).
• Open *.xcodeproj or *.xcworkspace
• Change name of Project.
• Click on schema and delete current chema and add new one.

Here is done, but name of window Xcode and *.xcodeproj or *.xcworkspace still <old-name>. Then I do:

• pop install
• Open <new name>.xcworkspace

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

I found applying the network and rebooting both the nodes did the trick for me.

kubectl apply -f [podnetwork].yaml

Unless you have sudo permissions to change it or its in your own usergroup/account you will not be able to get into it.

Check out man chmod in the terminal for more information about changing permissions of a directory.

Some Linux based MySQL installations require case sensitive. Work around is to apply nativeQuery.

@Query(value = 'select ID, CLUMN2, CLUMN3 FROM VENDOR c where c.ID = :ID', nativeQuery = true)

Use cbind e.g.

df <- data.frame(b = runif(6), c = rnorm(6))
cbind(a = 0, df)

giving:

> cbind(a = 0, df)
  a         b          c
1 0 0.5437436 -0.1374967
2 0 0.5634469 -1.0777253
3 0 0.9018029 -0.8749269
4 0 0.1649184 -0.4720979
5 0 0.6992595  0.6219001
6 0 0.6907937 -1.7416569

Do .libPaths(), close every R runing, check in the first directory, remove the zoo package restart R and install zoo again. Of course you need to have sufficient rights.

The best way is you should destroy the slick slider after reinitializing it.

function slickCarousel() {
  $('.skills_section').slick({
    infinite: true,
    slidesToShow: 3,
    slidesToScroll: 1
  });
}
function destroyCarousel() {
  if ($('.skills_section').hasClass('slick-initialized')) {
    $('.skills_section').slick('destroy');
  }      
}

$.ajax({
  type: 'get',
  url: '/public/index',
  dataType: 'script',
  data: data_send,
  success: function() {
    destroyCarousel()
    slickCarousel();
  }
});

I have seen many version of good answers here but it seems some folks are having cross browser issues so this is my fix.

I have used this successfully to detect direction in FF, IE and Chrome ... I haven't tested it in safari as I use windows typically.

$("html, body").bind({'mousewheel DOMMouseScroll onmousewheel touchmove scroll': 
    function(e) {
        if (e.target.id == 'el') return;
        e.preventDefault();
        e.stopPropagation();

        //Determine Direction
        if (e.originalEvent.wheelDelta && e.originalEvent.wheelDelta >= 0) {
            //Up
            alert("up");

        } else if (e.originalEvent.detail && e.originalEvent.detail <= 0) {
            //Up
            alert("up");

        } else {
            //Down
            alert("down");
        }
    }
});

Keep in mind I also use this to stop any scrolling so if you want scrolling to still occur you must remove the e.preventDefault(); e.stopPropagation();

This is a common question. In base, the option you're looking for is aggregate. Assuming your data.frame is called "mydf", you can use the following.

> aggregate(B ~ A, mydf, sum)
  A  B
1 1  5
2 2  3
3 3 11

I would also recommend looking into the "data.table" package.

> library(data.table)
> DT <- data.table(mydf)
> DT[, sum(B), by = A]
   A V1
1: 1  5
2: 2  3
3: 3 11

Try adding multiDexEnabled true to your app build.gradle file.

 defaultConfig {
    multiDexEnabled true
}

EDIT:

Try Steve's answer first. In case it happens frequently or first step didn't help multiDexEnabled might help. For those who love to dig deeper here is couple similar issues (with more answers):

How to create multiple plots from a dictionary of dataframes with long (tidy) data

• Assumptions

  • There is a dictionary of multiple dataframes of tidy data
    • Created by reading in from files
    • Created by separating a single dataframe into multiple dataframes
  • The categories, cat, may be overlapping, but all dataframes may not contain all values of cat
  • hue='cat'

• Because dataframes are being iterated through, there's not guarantee that colors will be mapped the same for each plot

  • A custom color map needs to be created from the unique 'cat' values for all the dataframes
  • Since the colors will be the same, place one legend to the side of the plots, instead of a legend in every plot

Imports and synthetic data

import pandas as pd
import numpy as np  # used for random data
import random  # used for random data
import matplotlib.pyplot as plt
from matplotlib.patches import Patch  # for custom legend
import seaborn as sns
import math import ceil  # determine correct number of subplot


# synthetic data
df_dict = dict()
for i in range(1, 7):
    np.random.seed(i)
    random.seed(i)
    data_length = 100
    data = {'cat': [random.choice(['A', 'B', 'C']) for _ in range(data_length)],
            'x': np.random.rand(data_length),
            'y': np.random.rand(data_length)}
    df_dict[i] = pd.DataFrame(data)


# display(df_dict[1].head())

  cat         x         y
0   A  0.417022  0.326645
1   C  0.720324  0.527058
2   A  0.000114  0.885942
3   B  0.302333  0.357270
4   A  0.146756  0.908535

Create color mappings and plot

# create color mapping based on all unique values of cat
unique_cat = {cat for v in df_dict.values() for cat in v.cat.unique()}  # get unique cats
colors = sns.color_palette('husl', n_colors=len(unique_cat))  # get a number of colors
cmap = dict(zip(unique_cat, colors))  # zip values to colors

# iterate through dictionary and plot
col_nums = 3  # how many plots per row
row_nums = math.ceil(len(df_dict) / col_nums)  # how many rows of plots
plt.figure(figsize=(10, 5))  # change the figure size as needed
for i, (k, v) in enumerate(df_dict.items(), 1):
    plt.subplot(row_nums, col_nums, i)  # create subplots
    p = sns.scatterplot(data=v, x='x', y='y', hue='cat', palette=cmap)
    p.legend_.remove()  # remove the individual plot legends
    plt.title(f'DataFrame: {k}')

plt.tight_layout()
# create legend from cmap
patches = [Patch(color=v, label=k) for k, v in cmap.items()]
# place legend outside of plot; change the right bbox value to move the legend up or down
plt.legend(handles=patches, bbox_to_anchor=(1.06, 1.2), loc='center left', borderaxespad=0)
plt.show()

or hide any br that follows the p tag, which are obviously not wanted

p + br {
    display: none;
}

In the VSCode file tasks.json, the "command": "tsc" will try to find the tsc windows command script in some folder that it deems to be your modules folder.

If you know where the command npm install -g typescript or npm install typescript is saving to, I would recommend replacing:

"command": "tsc"

with

"command": "D:\\Projects\\TS\\Tutorial\\node_modules\\.bin\\tsc"

where D:\\...\\bin is the folder that contains my tsc windows executable

Will determine where my vscode is natively pointing to right now to find the tsc and fix it I guess.

Find the below-mentioned code, it might be helpful for you.

   val stringDate = spark.sparkContext.parallelize(Seq("12/16/2019")).toDF("StringDate")
                    val dateCoversion = stringDate.withColumn("dateColumn", to_date(unix_timestamp($"StringDate", "dd/mm/yyyy").cast("Timestamp")))
                    dateCoversion.show(false)
+----------+----------+
|StringDate|dateColumn|
+----------+----------+
|12/16/2019|2019-01-12|
+----------+----------+

I had the same problem and I solved by using the postcast server. You can install it locally and use it.

to remove all '\' from a string, simply do the following:

myString = myString.Replace("\\", "");

This is untested, but something like this should work.

var myElement = $('#myElement');
myElement.css({
    position: 'absolute',
    left: '50%',
    'margin-left': 0 - (myElement.width() / 2)
});

I've always thought that DLLs and shared objects are just different terms for the same thing - Windows calls them DLLs, while on UNIX systems they're shared objects, with the general term - dynamically linked library - covering both (even the function to open a .so on UNIX is called dlopen() after 'dynamic library').

They are indeed only linked at application startup, however your notion of verification against the header file is incorrect. The header file defines prototypes which are required in order to compile the code which uses the library, but at link time the linker looks inside the library itself to make sure the functions it needs are actually there. The linker has to find the function bodies somewhere at link time or it'll raise an error. It ALSO does that at runtime, because as you rightly point out the library itself might have changed since the program was compiled. This is why ABI stability is so important in platform libraries, as the ABI changing is what breaks existing programs compiled against older versions.

Static libraries are just bundles of object files straight out of the compiler, just like the ones that you are building yourself as part of your project's compilation, so they get pulled in and fed to the linker in exactly the same way, and unused bits are dropped in exactly the same way.

I had troubles compiling all the most commonly mentioned cryptography libraries on my Windows 7 system and for Python 3.5.

This is the solution that finally worked for me.

from cryptography.fernet import Fernet
key = Fernet.generate_key() #this is your "password"
cipher_suite = Fernet(key)
encoded_text = cipher_suite.encrypt(b"Hello stackoverflow!")
decoded_text = cipher_suite.decrypt(encoded_text)

UPDATE  t1
LEFT JOIN
        t2
ON      t2.id = t1.id
SET     t1.col1 = newvalue
WHERE   t2.id IS NULL

Note that for a SELECT it would be more efficient to use NOT IN / NOT EXISTS syntax:

SELECT  t1.*
FROM    t1
WHERE   t1.id NOT IN
        (
        SELECT  id
        FROM    t2
        )

See the article in my blog for performance details:

• Finding incomplete orders: performance of LEFT JOIN compared to NOT IN

Unfortunately, MySQL does not allow using the target table in a subquery in an UPDATE statement, that's why you'll need to stick to less efficient LEFT JOIN syntax.

Try this:

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;

public class Main {

    public static void main(String[] argv) throws Exception {

    JTextField textField = new JTextField();

    textField.addKeyListener(new Keychecker());

    JFrame jframe = new JFrame();

    jframe.add(textField);

    jframe.setSize(400, 350);

    jframe.setVisible(true);

}

class Keychecker extends KeyAdapter {

    @Override
    public void keyPressed(KeyEvent event) {

        char ch = event.getKeyChar();

        System.out.println(event.getKeyChar());

    }

}

For me it was on line 183, but it only works after you reboot your computer. I wish there was a way to quickly change it without having to reboot each time, but for now that's the only way I know how.

transient is the solution for me. thanks! it's native to Java and avoids you to add another framework-specific annotation.

Your formulation is almost correct. You want:

subset(dat, ID=="P1" | ID=="P3") 

Where the | ('pipe') means 'or'. Your solution, ID=="P1 & P3", is looking for a case where ID is literally "P1 & P3"

Edit: Updated css to match with what you have..

DEMO

HTML

<div>
    <span class="close-btn"><a href="#">X</a></span>
</div>

CSS

.close-btn {
    border: 2px solid #c2c2c2;
    position: relative;
    padding: 1px 5px;
    top: -20px;
    background-color: #605F61;
    left: 198px;
    border-radius: 20px;
}

.close-btn a {
    font-size: 15px;
    font-weight: bold;
    color: white;
    text-decoration: none;
}

As per the javadoc of NotEmpty, Integer is not a valid type for it to check. It's for Strings and collections. If you just want to make sure an Integer has some value, javax.validation.constraints.NotNull is all you need.

public @interface NotEmpty

Asserts that the annotated string, collection, map or array is not null or empty.

Some of the solutions described here did not work for me. Others did, however they produced warnings on runtime and javadoc was still not linked. After some experimenting, I managed to solve this. The steps are:

1. Install the Google Play Services as recommended on Android Developers.

2. Set up your project as recommended on Android Developers.

3. If you followed 1. and 2., you should see two projects in your workspace: your project and google-play-services_lib project. Copy the docs folder which contains the javadoc from <android-sdk>/extras/google/google_play_services/ to libs folder of your project.

4. Copy google-play-services.jar from <android-sdk>/extras/google/google_play_services/libproject/google-play-services_lib/libs to 'libs' folder of your project.

5. In google-play-services_lib project, edit libs/google-play-services.jar.properties . The <path> in doc=<path> should point to the subfolder reference of the folder docs, which you created in step 3.

6. In Eclipse, do Project > Clean. Done, javadoc is now linked.

Writing the properties file with multiple comments is not supported. Why ?

PropertyFile.java

public class PropertyFile extends Task {

    /* ========================================================================
     *
     * Instance variables.
     */

    // Use this to prepend a message to the properties file
    private String              comment;

    private Properties          properties;

The ant property file task is backed by a java.util.Properties class which stores comments using the store() method. Only one comment is taken from the task and that is passed on to the Properties class to save into the file.

The way to get around this is to write your own task that is backed by commons properties instead of java.util.Properties. The commons properties file is backed by a property layout which allows settings comments for individual keys in the properties file. Save the properties file with the save() method and modify the new task to accept multiple comments through <comment> elements.

Swift 5. To see IF A DATE HAS PASSED:

let expiryDate = "2020-01-10" // Jan 10 2020

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

if Date() < dateFormatter.date(from: expiryDate) ?? Date() {
    print("Not Yet expiryDate")
} else {
    print("expiryDate has passed")
}

I got over this issue by using git merge command with the --no-commit option and then explicitly removed the staged file and ignore the changes to the file. E.g.: say I want to ignore any changes to myfile.txt I proceed as follows:

git merge --no-ff --no-commit <merge-branch>
git reset HEAD myfile.txt
git checkout -- myfile.txt
git commit -m "merged <merge-branch>"

You can put statements 2 & 3 in a for loop, if you have a list of files to skip.

import re
s = "many   fancy word \nhello    \thi"
re.split('\s+', s)

I believe this is controlled by the css color property applied to the element.

Use this if you're in the fragment.

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

            getFragmentManager().beginTransaction().remove((Fragment) youfragmentname).commitAllowingStateLoss();

        }

You cannot safely do what you want since the default hashCode() may not return the address, and has been mentioned, multiple objects with the same hashCode are possible. The only way to accomplish what you want, is to actually override the hashCode() method for the objects in question and guarantee that they all provide unique values. Whether this is feasible in your situation is another question.

For the record, I have experienced multiple objects with the same default hashcode in an IBM VM running in a WAS server. We had a defect where objects being put into a remote cache would get overwritten because of this. That was an eye opener for me at that point since I assumed the default hashcode was the objects memory address as well.

The hex values are on the mainpage of http://glyphicons.com/ in the tooltips of the specific icon.

I believe you need to specify "Option Infer On" for this to work.

Option Infer allows the compiler to make a guess at what is being represented by your code, thus it will guess that {"stuff"} is an array of strings. With "Option Infer Off", {"stuff"} won't have any type assigned to it, ever, and so it will always fail, without a type specifier.

Option Infer is, I think On by default in new projects, but Off by default when you migrate from earlier frameworks up to 3.5.

Opinion incoming:

Also, you mention that you've got "Option Explicit Off". Please don't do this.

Setting "Option Explicit Off" means that you don't ever have to declare variables. This means that the following code will silently and invisibly create the variable "Y":

Dim X as Integer
Y = 3

This is horrible, mad, and wrong. It creates variables when you make typos. I keep hoping that they'll remove it from the language.

This link explains the requirement you have step by step. If You are not really concerned which certificate you can proceed with the process in below link.

Note You might want to double check what you are doing since, this is a unsafe operation.

Follow These step to Remove " bash export command not found." Terminal open error fix>>>>>>

open terminal and type : root@someone:~# nano ~/.bashrc

After Loading nano: remove the all 'export PATH = ...........................' lines and press ctrl+o to save file and press ctrl+e to exit.

Now the Terminal opening error will be fixed.........

And a PHP example, multiple matching lines will be displayed:

<?php
$file = 'somefile.txt';
$searchfor = 'name';

// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');

// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
// escape special characters in the query
$pattern = preg_quote($searchfor, '/');
// finalise the regular expression, matching the whole line
$pattern = "/^.*$pattern.*\$/m";
// search, and store all matching occurences in $matches
if(preg_match_all($pattern, $contents, $matches)){
   echo "Found matches:\n";
   echo implode("\n", $matches[0]);
}
else{
   echo "No matches found";
}

You need to escape < and &. Escaping > too doesn't hurt:

function magic(input) {
    input = input.replace(/&/g, '&');
    input = input.replace(/</g, '&lt;');
    input = input.replace(/>/g, '&gt;');
    return input;
}

Or you let the DOM engine do the dirty work for you (using jQuery because I'm lazy):

function magic(input) {
    return $('<span>').text(input).html();
}

What this does is creating a dummy element, assigning your string as its textContent (i.e. no HTML-specific characters have side effects since it's just text) and then you retrieve the HTML content of that element - which is the text but with special characters converted to HTML entities in cases where it's necessary.

Across all browsers and simple. this did it for me

$(function () {_x000D_
     $('input[type="file"]').change(function () {_x000D_
          if ($(this).val() != "") {_x000D_
                 $(this).css('color', '#333');_x000D_
          }else{_x000D_
                 $(this).css('color', 'transparent');_x000D_
          }_x000D_
     });_x000D_
})

input[type="file"]{_x000D_
    color: transparent;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="file" name="app_cvupload" class="fullwidth input rqd">

You need to use ajax.

http://api.jquery.com/jQuery.ajax/

<code>
$.ajax({
  url: 'ajax/test.html',
  success: function(data) {
    $('.result').html(data);
    alert('Load was performed.');
  }
});
</code>

The character 0x0C is be invalid in XML 1.0 but would be a valid character in XML 1.1. So unless the xml file specifies the version as 1.1 in the prolog it is simply invalid and you should complain to the producer of this file.

You need to assign different classes to each table.

Create a class in CSS with the dot '.' operator and write your properties inside each class. For example,

.table1 {
//some properties
}

.table2 {
//Some other properties
}

and use them in your html code.

First you need to start karma server with

karma start

Then, you can use grep to filter a specific test or describe block:

karma run -- --grep=testDescriptionFilter

Depends a lot on your definition of what a "character" is. If "rune equals a character " is OK for your task (generally it isn't) then the answer by VonC is perfect for you. Otherwise, it should be probably noted, that there are few situations where the number of runes in a Unicode string is an interesting value. And even in those situations it's better, if possible, to infer the count while "traversing" the string as the runes are processed to avoid doubling the UTF-8 decode effort.

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

Regarding the answer from Michael Wyraz, where you use alt*DeploymentRepository in your settings.xml or command on the line, be careful if you are using version 3.0.0-M1 of the maven-deploy-plugin (which is the latest version at the time of writing), there is a bug in this version that could cause a server authentication issue.

A workaround is as follows. In the value:

releases::default::https://YOUR_NEXUS_URL/releases

you need to remove the default section, making it:

releases::https://YOUR_NEXUS_URL/releases

The prior version 2.8.2 does not have this bug.

Swift 4

button.titleLabel?.font = UIFont(name: "Font_Name_Here", size: Font_Size_Here)

Objective-c

[button.titleLabel setFont:[UIFont fontWithName:@“Font_Name_Here” size: Font_Size_Here]];

Example:

Font_Name = "Helvetica"

Font_Size = 16.0

Hope it helps.

I don't know why but for me the solution proposed by Marius Stanescu is breaking the specificity of col (a col-md-3 followed by a col-md-4 will take all of the twelve row)

I found another working solution :

.bottom-column 
{
   display: inline-block;
   vertical-align: middle;
   float: none;
}

This answer doesn't necessarily scale but only requires minor adjustments as the list grows. Semantically it might seem a little counter-intuitive since it is two lists, but aside from that it'll look the way you want in any browser ever made.

ul {_x000D_
  float: left;_x000D_
}_x000D_
_x000D_
ul > li {_x000D_
  width: 6em;_x000D_
}

<!-- Column 1 -->_x000D_
<ul>_x000D_
  <li>Item 1</li>_x000D_
  <li>Item 2</li>_x000D_
  <li>Item 3</li>_x000D_
</ul>_x000D_
<!-- Column 2 -->_x000D_
<ul>_x000D_
  <li>Item 4</li>_x000D_
  <li>Item 5</li>_x000D_
  <li>Item 6</li>_x000D_
</ul>

As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub. The simplest way is to change location to str(location) when using re.sub. It wouldn't hurt to do it anyways even if it's already a str.

letters_only = re.sub("[^a-zA-Z]",  # Search for all non-letters
                          " ",          # Replace all non-letters with spaces
                          str(location))

I don't know whether a direct way of doing this is available or not, but you surely there is a workaround via code: listen for onFocus event of EditText, and as soon it gains focus, set the hint to be nothing with something like editText.setHint(""):

This may not be exactly what you have to do, but it may be something like this-

myEditText.setOnFocusListener(new OnFocusListener(){
  public void onFocus(){
    myEditText.setHint("");
  }
});

The function sizeof returns the number of bytes which is used by your array in the memory. If you want to calculate the number of elements in your array, you should divide that number with the sizeof variable type of the array. Let's say int array[10];, if variable type integer in your computer is 32 bit (or 4 bytes), in order to get the size of your array, you should do the following:

int array[10];
int sizeOfArray = sizeof(array)/sizeof(int);

You are building a DataGridView on the fly and set the DataSource for it. That's good, but then do you add the DataGridView to the Controls collection of the hosting form?

this.Controls.Add(dataGridView1);

By the way the code is a bit confused

String connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\\Tables.accdb;Persist Security Info=True";
string sql  = "SELECT Clients  FROM Tables";
using(OleDbConnection conn = new OleDbConnection(connection))
{
     conn.Open();
     DataSet ds = new DataSet();
     DataGridView dataGridView1 = new DataGridView();
     using(OleDbDataAdapter adapter = new OleDbDataAdapter(sql,conn))
     {
         adapter.Fill(ds);
         dataGridView1.DataSource = ds;
         // Of course, before addint the datagrid to the hosting form you need to 
         // set position, location and other useful properties. 
         // Why don't you create the DataGrid with the designer and use that instance instead?
         this.Controls.Add(dataGridView1);
     }
}

EDIT After the comments below it is clear that there is a bit of confusion between the file name (TABLES.ACCDB) and the name of the table CLIENTS.
The SELECT statement is defined (in its basic form) as

 SELECT field_names_list FROM _tablename_

so the correct syntax to use for retrieving all the clients data is

 string sql  = "SELECT * FROM Clients";

where the * means -> all the fields present in the table

Related to this I had to find a fix where animated gifs were used as a background image to ensure styling was kept to the stylesheet. A similar fix worked for me there too... my script went something like this (I'm using jQuery to make it easier to get the computed background style - how to do that without jQuery is a topic for another post):

var spinner = <give me a spinner element>

window.onbeforeunload = function() {
  bg_image = $(spinner).css('background-image');
  spinner.style.backgroundImage = 'none';
  spinner.style.backgroundImage = bg_image;
}

[EDIT] With a bit more testing I've just realised that this doesn't work with background images in IE8. I've been trying everything I can think of to get IE8 to render a gif animation wile loading a page, but it doesn't look possible at this time.

From RFC 7034:

Wildcards or lists to declare multiple domains in one ALLOW-FROM statement are not permitted

So,

How do I set the X-Frame-Options: ALLOW-FROM to support more than a single domain?

You can't. As a workaround you can use different URLs for different partners. For each URL you can use it's own X-Frame-Options value. For example:

partner   iframe URL       ALLOW-FROM
---------------------------------------
Facebook  fb.yoursite.com  facebook.com
VK.COM    vk.yoursite.com  vk.com

For yousite.com you can just use X-Frame-Options: deny.

BTW, for now Chrome (and all webkit-based browsers) does not support ALLOW-FROM statements at all.

Warning: This might inflate executable file size a little bit and cost a little runtime performance. IMO, this would be better if golang has such feature like macro or function decorator.

If you want to mock functions without changing its API, the easiest way is to change the implementation a little bit:

func getPage(url string) string {
  if GetPageMock != nil {
    return GetPageMock()
  }

  // getPage real implementation goes here!
}

func downloader() {
  if GetPageMock != nil {
    return GetPageMock()
  }

  // getPage real implementation goes here!
}

var GetPageMock func(url string) string = nil
var DownloaderMock func() = nil

This way we can actually mock one function out of the others. For more convenient we can provide such mocking boilerplate:

// download.go
func getPage(url string) string {
  if m.GetPageMock != nil {
    return m.GetPageMock()
  }

  // getPage real implementation goes here!
}

func downloader() {
  if m.GetPageMock != nil {
    return m.GetPageMock()
  }

  // getPage real implementation goes here!
}

type MockHandler struct {
  GetPage func(url string) string
  Downloader func()
}

var m *MockHandler = new(MockHandler)

func Mock(handler *MockHandler) {
  m = handler
}

In test file:

// download_test.go
func GetPageMock(url string) string {
  // ...
}

func TestDownloader(t *testing.T) {
  Mock(&MockHandler{
    GetPage: GetPageMock,
  })

  // Test implementation goes here!

  Mock(new(MockHandler)) // Reset mocked functions
}

Concurrent signal assignment:

library ieee;
use ieee.std_logic_1164.all;

entity foo is
end;
architecture behave of foo is
    signal clk: std_logic := '0';
begin
CLOCK:
clk <=  '1' after 0.5 ns when clk = '0' else
        '0' after 0.5 ns when clk = '1';
end;

ghdl -a foo.vhdl
ghdl -r foo --stop-time=10ns --wave=foo.ghw
ghdl:info: simulation stopped by --stop-time
gtkwave foo.ghw

Simulators simulate processes and it would be transformed into the equivalent process to your process statement. Simulation time implies the use of wait for or after when driving events for sensitivity clauses or sensitivity lists.

Follow the instructions at https://gist.github.com/application2000/73fd6f4bf1be6600a2cf9f56315a2d91 to set up the gcc version you need - gcc 5 or gcc 6 - on Ubuntu 14.04. The instructions include configuring update-alternatives to allow you to switch between versions as you need to.

I was going to write up my own explanation but this Wikipedia article pretty much sums it up.

Here is the basic concept:

Copy-on-write (sometimes referred to as "COW") is an optimization strategy used in computer programming. The fundamental idea is that if multiple callers ask for resources which are initially indistinguishable, you can give them pointers to the same resource. This function can be maintained until a caller tries to modify its "copy" of the resource, at which point a true private copy is created to prevent the changes becoming visible to everyone else. All of this happens transparently to the callers. The primary advantage is that if a caller never makes any modifications, no private copy need ever be created.

Also here is an application of a common use of COW:

The COW concept is also used in maintenance of instant snapshot on database servers like Microsoft SQL Server 2005. Instant snapshots preserve a static view of a database by storing a pre-modification copy of data when underlaying data are updated. Instant snapshots are used for testing uses or moment-dependent reports and should not be used to replace backups.

You must set Preserving Object References:

var jsonSerializerSettings = new JsonSerializerSettings
{
    PreserveReferencesHandling = PreserveReferencesHandling.Objects
};

Then call your query var q = (from a in db.Events where a.Active select a).ToList(); like

string jsonStr = Newtonsoft.Json.JsonConvert.SerializeObject(q, jsonSerializerSettings);

See: https://www.newtonsoft.com/json/help/html/PreserveObjectReferences.htm

Just came across the same issue today...

In order to create a list of lists you will have firstly to store your data, array, or other type of variable into a list. Then, create a new empty list and append to it the lists that you just created. At the end you should end up with a list of lists:

list_1=data_1.tolist()
list_2=data_2.tolist()
listoflists = []
listoflists.append(list_1)
listoflists.append(list_2)

Another workaround would be to initiate a modal window containing its own form

There is an API for unsigned Integer and Long in Java 8!

Try as

String s = "ABC[ This is to extract ]";
        Pattern p = Pattern.compile(".*\\[ *(.*) *\\].*");
        Matcher m = p.matcher(s);
        m.find();
        String text = m.group(1);
        System.out.println(text);

I think that for SQL Server Local Db you shouldn't use the Initial Catalog property. I suggest to use:

<add name="DefaultConnection" 
     connectionString="Data Source=(LocalDb)\v11.0;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\OdeToFoodDb.mdf" 
     providerName="System.Data.SqlClient" />

I think that local db doesn't support multiple database on the same mdf file so specify an initial catalog is not supported (or not well supported and I have some strange errors).

        new_num_string=remainder_string+new_num_string

    return new_num_string

Here's another one from the same link

def baseconvert(n, base):
    """convert positive decimal integer n to equivalent in another base (2-36)"""

    digits = "0123456789abcdefghijklmnopqrstuvwxyz"

    try:
        n = int(n)
        base = int(base)
    except:
        return ""

    if n < 0 or base < 2 or base > 36:
        return ""

    s = ""
    while 1:
        r = n % base
        s = digits[r] + s
        n = n / base
        if n == 0:
            break

    return s

With Equals() you can also use a Yoda condition:

if ( ! "-1".Equals(myString) )

The page sizes are looking different in your PDF because the images were originally set to different DPI (even if images are identical HxW in pixels). The good news is - it's only a display issue - and can be fixed easily.

An image with a higher DPI value would display smaller in a PDF (displays at the 'print-size' of the image). To avoid this, open each image in an image editor like GIMP or Photoshop. Open relevant image print control dialog box and set a suitable uniform DPI info for all the images. Remake the PDF with these new images. If in the new PDF images are too big - redo the DPI setting for each to a higher value. If in the new PDF pages are too small to read on-screen without zooming, again - redo DPI adjustment, this time put a lower DPI value. Ideally, 150 DPI should be good enough for images of 2500X2500 pixel - on a 17 inch monitor set to 1366x768 resolution.

BTW, the PDF file shall print each page at the specified DPI of that page. If all images are same DPI, you'll get a uniform printing.

Hope this helps :)

I found a solution for myself

var acService = new google.maps.places.AutocompleteService();
var autocompleteItems = [];

acService.getPlacePredictions({
    types: ['(regions)']
}, function(predictions) {
    predictions.forEach(function(prediction) {
        if (prediction.types.some(function(x) {
                return x === "country" || x === "administrative_area1" || x === "locality";
            })) {
            if (prediction.terms.length < 3) {
                autocompleteItems.push(prediction);
            }
        }
    });
});

this solution only show city and country..

Simply copy the file, add and commit it:

cp dir1/A.txt dir2/A.txt
git add dir2/A.txt
git commit -m "Duplicated file from dir1/ to dir2/"

Then the following commands will show the full pre-copy history:

git log --follow dir2/A.txt

To see inherited line-by-line annotations from the original file use this:

git blame -C -C -C dir2/A.txt

Git does not track copies at commit-time, instead it detects them when inspecting history with e.g. git blame and git log.

Most of this information comes from the answers here: Record file copy operation with Git

Using the backtick (`) works fine for me if I put them in the following places:

$cmd="\\server\toto.exe -batch=B -param=`"sort1;parmtxt='Security ID=1234'`""

$cmd returns as:

\\server\toto.exe -batch=B -param="sort1;parmtxt='Security ID=1234'"

Is that what you were looking for?

The error PowerShell gave me referred to an unexpected token 'sort1', and that's how I determined where to put the backticks.

The @' ... '@ syntax is called a "here string" and will return exactly what is entered. You can also use them to populate variables in the following fashion:

$cmd=@'
"\\server\toto.exe -batch=B -param="sort1;parmtxt='Security ID=1234'""
'@

The opening and closing symbols must be on their own line as shown above.

Here is another example that return's a boolean value using try/catch.

private boolean doSomeThing(int index){
    try {
        if(index%2==0) 
            return true; 
    } catch (Exception e) {
        System.out.println(e.getMessage()); 
    }finally {
        System.out.println("Finally!!! ;) ");
    }
    return false; 
}

NSString* NSStringWithoutSpace(NSString* string)
{
    return [string stringByReplacingOccurrencesOfString:@" " withString:@""];
}

Based on what I've read and my experience with Django so far, auto_now_add is buggy. I agree with jthanism --- override the normal save method it's clean and you know what's hapenning. Now, to make it dry, create an abstract model called TimeStamped:

from django.utils import timezone

class TimeStamped(models.Model):
    creation_date = models.DateTimeField(editable=False)
    last_modified = models.DateTimeField(editable=False)

    def save(self, *args, **kwargs):
        if not self.creation_date:
            self.creation_date = timezone.now()

        self.last_modified = timezone.now()
        return super(TimeStamped, self).save(*args, **kwargs)

    class Meta:
        abstract = True

And then, when you want a model that has this time-stampy behavior, just subclass:

MyNewTimeStampyModel(TimeStamped):
    field1 = ...

If you want the fields to show up in admin, then just remove the editable=False option

Arrays have O(1) random access, but are really expensive to add stuff onto or remove stuff from.

Linked lists are really cheap to add or remove items anywhere and to iterate, but random access is O(n).

create a virtual environment, install then switch to python 3.6.5

$ conda create -n tensorflow python=3.7
$ conda activate tensorflow
$ conda install python=3.6.5
$ pip install tensorflow

activate the environment when you would want to use tensorflow

For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

This is better way

let new_row = document.createElement('div');
new_row.setAttribute("class", "classname");
new_row.setAttribute("id", "idname");

Try it ;) Just watch the content of the FrameLayout(@id/tabcontent), because I don't know how it will handle in case of scrolling... In my case it works because I used ListView as the content of my tabs. :) Hope it helps.

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

        android:layout_width="fill_parent" 
        android:layout_height="fill_parent">
        <FrameLayout android:id="@android:id/tabcontent"
             android:layout_width="fill_parent" 
             android:layout_height="fill_parent"
             android:layout_alignParentTop="true" 
             android:layout_above="@android:id/tabs" />
    <TabWidget android:id="@android:id/tabs"
             android:layout_width="fill_parent" 
             android:layout_height="wrap_content"
             android:layout_alignParentBottom="true" />

There is a a new option as well: get it via pip! There is a package pypiwin32 with wheels available, so you can just install with: pip install pypiwin32!

Edit: Per comment from @movermeyer, the main project now publishes wheels at pywin32, and so can be installed with pip install pywin32

As already mentioned there are different options and file formats (HDF5, JSON, CSV, parquet, SQL) to store a data frame. However, pickle is not a first-class citizen (depending on your setup), because:

1. pickle is a potential security risk. Form the Python documentation for pickle:

Warning The pickle module is not secure against erroneous or maliciously constructed data. Never unpickle data received from an untrusted or unauthenticated source.

2. pickle is slow. Find here and here benchmarks.

Depending on your setup/usage both limitations do not apply, but I would not recommend pickle as the default persistence for pandas data frames.

I faced the same issue but the reason was none of the ones listed above. I created a task, created a scope inside the task and asked the container to obtain a service. That worked fine but then I used a second service inside the task and I forgot to also asked for it to the new scope. Because of that, the 2nd service was using a DbContext that was already disposed.

Task task = Task.Run(() =>
    {
        using (var scope = serviceScopeFactory.CreateScope())
        {
            var otherOfferService = scope.ServiceProvider.GetService<IOfferService>();
            // everything was ok here. then I did: 
            productService.DoSomething(); // (from the main scope) and this failed because the db context associated to that service was already disposed.
            ...
        }
    }

I should have done this:

var otherProductService = scope.ServiceProvider.GetService<IProductService>();
otherProductService.DoSomething();

1. Go to the directory

   cd /usr/local
   

2. Remove it with super user privileges

   sudo rm -rf go
   

There two ways, what I found either go to the directory where kernels are residing and delete from there. Secondly, using this command below

List all kernels and grap the name of the kernel you want to remove

 jupyter kernelspec list 

to get the paths of all your kernels.

Then simply uninstall your unwanted-kernel

jupyter kernelspec remove kernel_name

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

In case you ever get stuck during a merge/rebase you can always

git reset --hard

to restore your working to the state of the last commit. This will lose your changes from the working tree so if you had local modifications before the merge they will be gone after this—which is why it’s advisable to not start a merge when you have local modifications. :)

Use CSS styles with CSS Classes instead

CSS

.error {
  border:2px solid red;
}

Now in Javascript

document.getElementById("fName").className = document.getElementById("fName").className + " error";  // this adds the error class

document.getElementById("fName").className = document.getElementById("fName").className.replace(" error", ""); // this removes the error class

The main reason I mention this is suppose you want to change the color of the errored element's border. If you choose your way you will may need to modify many places in code. If you choose my way you can simply edit the style sheet.

To select all characters except the last n from a string (or put another way, remove last n characters from a string); use the SUBSTRING and CHAR_LENGTH functions together:

SELECT col
     , /* ANSI Syntax  */ SUBSTRING(col FROM 1 FOR CHAR_LENGTH(col) - 2) AS col_trimmed
     , /* MySQL Syntax */ SUBSTRING(col,     1,    CHAR_LENGTH(col) - 2) AS col_trimmed
FROM tbl

To remove a specific substring from the end of string, use the TRIM function:

SELECT col
     , TRIM(TRAILING '.php' FROM col)
-- index.php becomes index
-- index.txt remains index.txt

I can't get it to work on $.get() because it has no complete event.

I suggest to use $.ajax() like this,

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

If you are using python2.7 or above you can use the ability of assertRaises to be use as a context manager and do:

with self.assertRaises(TypeError):
    self.testListNone[:1]

If you are using python2.6 another way beside the one given until now is to use unittest2 which is a back port of unittest new feature to python2.6, and you can make it work using the code above.

N.B: I'm a big fan of the new feature (SkipTest, test discovery ...) of unittest so I intend to use unittest2 as much as I can. I advise to do the same because there is a lot more than what unittest come with in python2.6 <.

If appears to me that rows where Visible is set to false won't be accessible, that they are removed from the DOM rather than hidden, so I also used the Display: None approach. In my case, I wanted to have a hidden column that contained the key of the Row. To me, this declarative approach is a little cleaner than some of the other approaches that use code.

<style>
   .HiddenCol{display:none;}                
</style>


 <%--ROW ID--%>
      <asp:TemplateField HeaderText="Row ID">
       <HeaderStyle CssClass="HiddenCol" />
       <ItemTemplate>
       <asp:Label ID="lblROW_ID" runat="server" Text='<%# Bind("ROW_ID") %>'></asp:Label>
       </ItemTemplate>
       <ItemStyle HorizontalAlign="Right" CssClass="HiddenCol" />
       <EditItemTemplate>
       <asp:TextBox ID="txtROW_ID" runat="server" Text='<%# Bind("ROW_ID") %>'></asp:TextBox>
       </EditItemTemplate>
       <FooterStyle CssClass="HiddenCol" />
      </asp:TemplateField>

If you want to use the new android.support.v7.app.AlertDialog and have different colors for the buttons and also have a custom layout then have a look at my https://gist.github.com/JoachimR/6bfbc175d5c8116d411e

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.custom_layout, null);

    initDialogUi(v);

    final AlertDialog d = new AlertDialog.Builder(activity, R.style.AppCompatAlertDialogStyle)
            .setTitle(getString(R.string.some_dialog_title))
            .setCancelable(true)
            .setPositiveButton(activity.getString(R.string.some_dialog_title_btn_positive),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            doSomething();
                            dismiss();
                        }
                    })
            .setNegativeButton(activity.getString(R.string.some_dialog_title_btn_negative),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dismiss();
                        }
                    })
            .setView(v)
            .create();

    // change color of positive button         
    d.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
            b.setTextColor(getResources().getColor(R.color.colorPrimary));
        }
    });

    return d;
}

You can also use Dot(.) for local key i.e;

Data Source=.\SQLEXPRESS;Initial Catalog=master;Integrated Security=True

If you have the default server instance i.e. MSSQLSERVER, then just use dot for Data Source.

Data Source=.;Initial Catalog=master;Integrated Security=True

Simply add the following to your custom CSS file. Editing Bootstrap CSS files directly is not recommended and cancels your ability to use a CDN.

.center-block {
    float: none !important
}

Why?

Bootstrap CSS (version 3.7 and lower) uses margin: 0 auto;, but it gets overridden by the float property of the size container.

PS:

After you add this class, don't forget to set classes by the right order.

<div class="col-md-6 center-block">Example</div>

insertAdjacentHTML + outerHTML

elementBefore.insertAdjacentHTML('afterEnd', elementAfter.outerHTML)

Upsides:

• DRYer: you don't have to store the before node in a variable and use it twice. If you rename the variable, on less occurrence to modify.
• golfs better than the insertBefore (break even if the existing node variable name is 3 chars long)

Downsides:

• lower browser support since newer: https://caniuse.com/#feat=insert-adjacent
• will lose properties of the element such as events because outerHTML converts the element to a string. We need it because insertAdjacentHTML adds content from strings rather than elements.

Because recursion is always the answer.

function getPosition(input, search, nth, curr, cnt) {
    curr = curr || 0;
    cnt = cnt || 0;
    var index = input.indexOf(search);
    if (curr === nth) {
        if (~index) {
            return cnt;
        }
        else {
            return -1;
        }
    }
    else {
        if (~index) {
            return getPosition(input.slice(index + search.length),
              search,
              nth,
              ++curr,
              cnt + index + search.length);
        }
        else {
            return -1;
        }
    }
}

You can solve this temporarily by using the Firefox add-on, CORS Everywhere. Just open Firefox, press Ctrl+Shift+A , search the add-on and add it!

Personally, I would shorten it a touch too if all you need is the columns:

For i = LBound(arr1) To UBound(arr1)
    Sheets("SheetA").Columns(arr1(i)).Copy
    Sheets("SheetB").Columns(arr2(i)).PasteSpecial xlPasteValues
    Application.CutCopyMode = False
Next

as from this code snippet, there isnt much point in lastrow or firstrowDB

+new is equivalent to +alloc/-init in Apple's NSObject implementation. It is highly unlikely that this will ever change, but depending on your paranoia level, Apple's documentation for +new appears to allow for a change of implementation (and breaking the equivalency) in the future. For this reason, because "explicit is better than implicit" and for historical continuity, the Objective-C community generally avoids +new. You can, however, usually spot the recent Java comers to Objective-C by their dogged use of +new.

It is possible to have hierarchical branch names (branch names with slash). For example in my repository I have such branch(es). One caveat is that you can't have both branch 'foo' and branch 'foo/bar' in repository.

Your problem is not with creating branch with slash in name.

$ git branch foo/bar
error: unable to resolve reference refs/heads/labs/feature: Not a directory
fatal: Failed to lock ref for update: Not a directory

The above error message talks about 'labs/feature' branch, not 'foo/bar' (unless it is a mistake in copy'n'paste, i.e you edited parts of session). What is the result of git branch or git rev-parse --symbolic-full-name HEAD?

Since :last-child is a CSS3 pseudo-class, it is not supported in IE8. I believe :first-child is supported, as it's defined in the CSS2.1 specification.

One possible solution is to simply give the last child a class name and style that class.

Another would be to use JavaScript. jQuery makes this particularly easy as it provides a :last-child pseudo-class which should work in IE8. Unfortunately, that could result in a flash of unstyled content while the DOM loads.

I can't find a scenario that cannot be solved using node-fibers. The example you provided using node-fibers behaves as expected. The key is to run all the relevant code inside a fiber, so you don't have to start a new fiber in random positions.

Lets see an example: Say you use some framework, which is the entry point of your application (you cannot modify this framework). This framework loads nodejs modules as plugins, and calls some methods on the plugins. Lets say this framework only accepts synchronous functions, and does not use fibers by itself.

There is a library that you want to use in one of your plugins, but this library is async, and you don't want to modify it either.

The main thread cannot be yielded when no fiber is running, but you still can create plugins using fibers! Just create a wrapper entry that starts the whole framework inside a fiber, so you can yield the execution from the plugins.

Downside: If the framework uses setTimeout or Promises internally, then it will escape the fiber context. This can be worked around by mocking setTimeout, Promise.then, and all event handlers.

So this is how you can yield a fiber until a Promise is resolved. This code takes an async (Promise returning) function and resumes the fiber when the promise is resolved:

framework-entry.js

console.log(require("./my-plugin").run());

async-lib.js

exports.getValueAsync = () => {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve("Async Value");
    }, 100);
  });
};

my-plugin.js

const Fiber = require("fibers");

function fiberWaitFor(promiseOrValue) {
  var fiber = Fiber.current, error, value;
  Promise.resolve(promiseOrValue).then(v => {
    error = false;
    value = v;
    fiber.run();
  }, e => {
    error = true;
    value = e;
    fiber.run();
  });
  Fiber.yield();
  if (error) {
    throw value;
  } else {
    return value;
  }
}

const asyncLib = require("./async-lib");

exports.run = () => {
  return fiberWaitFor(asyncLib.getValueAsync());
};

my-entry.js

require("fibers")(() => {
  require("./framework-entry");
}).run();

When you run node framework-entry.js it will throw an error: Error: yield() called with no fiber running. If you run node my-entry.js it works as expected.

    </form> 

This is a very basic PHP Form validation. This could be put in a try block, but for basic reference, I see this fit following our conversation in the comment box.

What this script will do, is process each of the post elements, and act accordingly, for example:

    if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
        {
            $ErrorArrays[] = "Incorrect Email Formatting";
        }

This will check:

if $Input_Email is not a valid email. If this is not a valid E-mail, then a message will get added to a empty array.

Further down the script, you will see:

    if (count($ErrorArrays) == 0)
    {
        // No Errors
    }
    else
    {
        foreach ($ErrorArrays AS $Errors)
        {
            echo "<font color='red'><b>".$Errors."</font></b><br>";
        }
    }

Basically. if the array count is not 0, errors have been found. Then the script will print out the errors.

Remember, this is a reference based on our conversation in the comment box, and should be used as such.

There is a really nice, easy to use, lightweight (uses native browser events for detection) plugin for both basic JavaScript and for jQuery that was released this year. It performs perfectly:

https://github.com/sdecima/javascript-detect-element-resize

This way you check if the string is not null and not empty, also considering the empty spaces:

boolean isEmpty = str == null || str.trim().length() == 0;
if (isEmpty) {
    // handle the validation
}

1. find the node and npm version you want to use from here https://nodejs.org/en/download/releases/
2. nvm use 8.11.4
3. you already got the npm 5.6 with node 8.11.4

Just go with nvm use node_version

I wonder whether the below method is what you want.

You can use defaultdict.

>>> from collections import defaultdict
>>> s = [('red',1), ('blue',2), ('red',3), ('blue',4), ('red',1), ('blue',4)]
>>> d = defaultdict(list)
>>> for k, v in s:
       d[k].append(v)    
>>> sorted(d.items())
[('blue', [2, 4, 4]), ('red', [1, 3, 1])]

Here is an example that lists all the files on my desktop. you should change the path variable to your path.

Instead of printing the file's name with System.out.println, you should place your own code to operate on the file.

public static void main(String[] args) {
    File path = new File("c:/documents and settings/Zachary/desktop");

    File [] files = path.listFiles();
    for (int i = 0; i < files.length; i++){
        if (files[i].isFile()){ //this line weeds out other directories/folders
            System.out.println(files[i]);
        }
    }
}

Writing this middleware might help !

app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With,     Content-Type, Accept");
next();
});

Looks like the usual suspects like pdfsharp and migradoc are not able to do that (pdfsharp only if you have Acrobat (Reader) installed).

I found here

https://vishalsbsinha.wordpress.com/2014/05/06/how-to-programmatically-c-net-print-a-pdf-file-directly-to-the-printer/

code ready for copy/paste. It uses the default printer and from what I can see it doesn't even use any libraries, directly sending the pdf bytes to the printer. So I assume the printer also needs to support it, on one 10 year old printer I tested this it worked flawlessly.

Most other approaches - without commercial libraries or applications - require you to draw yourself in the printing device context. Doable but will take a while to figure it out and make it work across printers.

For those under windows, you could also use the git-rocket-filter tool.

From the documentation:

Change commit author name and email:

git-rocket-filter --branch TestBranch --commit-filter '
    if (commit.AuthorName.Contains("Jim")) {   
        commit.AuthorName = "Paul"; 
        commit.AuthorEmail = "[email protected]"; 
    }

For my case, my another team member included another version of jquery.js when he add in bootstrap.min.js. After remove the extra jquery.js, the problem is solved

You can also use this:

<fieldset>
<input type="radio" name="myoptions[]" value="blue"> Blue<br />
<input type="radio" name="myoptions[]" value="red"> Red<br />
<input type="radio" name="myoptions[]" value="green"> Green<br />
<label for="myoptions[]" class="error" style="display:none;">Please choose one.</label>
</fieldset>

and simply add this rule

rules: {
 'myoptions[]':{ required:true }
}

Mention how to add rules.

This attribute helps to get the best knowledge of the activity associated with your layout. This is also useful when you have to add onClick handlers on a view using QuickFix.

tools:context=".MainActivity"

Invoke Code's Go to symbol command:

• macOS: cmd+shift+o (the letter o, not zero)

• Windows/Linux: ctrl+shift+o

Typing a colon (:) after invoking Go to symbol will group symbols by type (classes, interfaces, methods, properties, variables). Then just scroll to the methods section.

You can use geom_col() directly. See the differences between geom_bar() and geom_col() in this link https://ggplot2.tidyverse.org/reference/geom_bar.html

geom_bar() makes the height of the bar proportional to the number of cases in each group If you want the heights of the bars to represent values in the data, use geom_col() instead.

ggplot(data_country)+aes(x=country,y = conversion_rate)+geom_col()

 DateTime.Today.ToString("MM/dd/yy")

Look at the docs for custom date and time format strings for more info.

(Oh, and I hope this app isn't destined for other cultures. That format could really confuse a lot of people... I've never understood the whole month/day/year thing, to be honest. It just seems weird to go "middle/low/high" in terms of scale like that.)

When you go to a website, your browser sends a request to the web server including a lot of information. This information might look something like this:

GET /questions/18070154/get-operating-system-info-with-php HTTP/1.1  
Host: stackoverflow.com  
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 
            (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36 
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8  
Accept-Language: en-us,en;q=0.5  
Accept-Encoding: gzip,deflate,sdch  
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7  
Keep-Alive: 300  
Connection: keep-alive  
Cookie: <cookie data removed> 
Pragma: no-cache  
Cache-Control: no-cache

These information are all used by the web server to determine how to handle the request; the preferred language and whether compression is allowed.

In PHP, all this information is stored in the $_SERVER array. To see what you're sending to a web server, create a new PHP file and print out everything from the array.

<pre><?php print_r($_SERVER); ?></pre>

This will give you a nice representation of everything that's being sent to the server, from where you can extract the desired information, e.g. $_SERVER['HTTP_USER_AGENT'] to get the operating system and browser.

Bitbucket uses CodeMirror for syntax highlighting. For Bash or shell you can use sh, bash, or zsh. More information can be found at Configuring syntax highlighting for file extensions and Code mirror language modes.

It has worked for me as follows.

ed1.requestFocus();

            return; //Faça um return para retornar o foco

Javascript's String.fromCharCode(code1, code2, ..., codeN) takes an infinite number of arguments and returns a string of letters whose corresponding ASCII values are code1, code2, ... codeN. Since 97 is 'a' in ASCII, we can adjust for your indexing by adding 97 to your index.

function indexToChar(i) {
  return String.fromCharCode(i+97); //97 in ASCII is 'a', so i=0 returns 'a', 
                                    // i=1 returns 'b', etc
}

In addition to the still very relevant answer of jujule, I find it quite important to also be aware of the implications of order_by() on distinct("field_name") queries. This is, however, a Postgres only feature!

If you are using Postgres and if you define a field name that the query should be distinct for, then order_by() needs to begin with the same field name (or field names) in the same sequence (there may be more fields afterward).

Note

When you specify field names, you must provide an order_by() in the QuerySet, and the fields in order_by() must start with the fields in distinct(), in the same order.

For example, SELECT DISTINCT ON (a) gives you the first row for each value in column a. If you don’t specify an order, you’ll get some arbitrary row.

If you want to e-g- extract a list of cities that you know shops in , the example of jujule would have to be adapted to this:

# returns an iterable Queryset of cities.
models.Shop.objects.order_by('city').values_list('city', flat=True).distinct('city')  

Use mktime():

<?php
 $monthNum = 5;
 $monthName = date("F", mktime(0, 0, 0, $monthNum, 10));
 echo $monthName; // Output: May
?>

See the PHP manual : http://php.net/mktime

You can also use the setProperty method like below

document.getElementById('divName').style.setProperty("top", "100px");

You can always use the 'pre' tag inside the label, and just enter the blank spaces in it, So you can always add the same or different number of spaces you require

<form>
<label>First Name :<pre>Here just enter number of spaces you want to use(I mean using spacebar to enter blank spaces)</pre>
<input type="text"></label>
<label>Last Name :<pre>Now Enter enter number of spaces to match above number of 
spaces</pre>
<input type="text"></label>
</form>

Hope you like my answer, It's a simple and efficient hack

The way I do it is I have a bare Git repository on my deployment server where I push changes. Then I log in to the deployment server, change to the actual web server docs directory, and do a git pull. I don't use any hooks to try to do this automatically, that seems like more trouble than it's worth.

$("#bfCaptchaEntry").click(function(){
    myFunction();
});

If you always want the code collapsed by default, go to Windows > Preferences. Search for "folding". Then check all the items under "Initially fold these elements".

Try to get some debugging information, could be that the file path is wrong, for example.

Try these two things:- Add this line to the top of your sample page:

<?php error_reporting(E_ALL);?>

This will print all errors/warnings/notices in the page so if there is any problem you get a text message describing it instead of a blank page

Additionally you can change include() to require()

<?php require ('headings.php'); ?>
<?php require ('navbar.php'); ?>
<?php require ('image.php'); ?>

This will throw a FATAL error PHP is unable to load required pages, and should help you in getting better tracing what is going wrong..

You can post the error descriptions here, if you get any, and you are unable to figure out what it means..

I use jQuery.getJSON( url [, data ] [, success( data, textStatus, jqXHR ) ] ) for example:

var url="my.php";
$.getJSON( url, myObj )
.done(function( json ) { ... }) /* got JSON from server */
.fail(function( jqxhr, textStatus, error ) {
    var err = textStatus + ", " + error;
    console.log( "Failed to obtain JSON data from server: " + err );
  }); /* failed to get JSON */

getJSON is shorthand for:

$.ajax({
  dataType: "json",
  url: url,
  data: data,
  success: success
});

Windows Forms

For a Windows Forms version (no console window and we don't get around to actually creating any forms - though you can if you want).

Compile line in a command prompt.

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /t:winexe "%userprofile%\desktop\VBS2Exe.vb"

Text for VBS2EXE.vb

Imports System.Windows.Forms 

Partial Class MyForm : Inherits Form 

Private Sub InitializeComponent() 


End Sub

Public Sub New() 

InitializeComponent() 

End Sub

Public Shared Sub Main() 

Dim sc as object 
Dim Scrpt as string

sc = createObject("MSScriptControl.ScriptControl")

Scrpt = "msgbox " & chr(34) & "Hi there I'm a form" & chr(34)

With SC 
.Language = "VBScript" 
.UseSafeSubset = False 
.AllowUI = True 
End With


sc.addcode(Scrpt)


End Sub

End Class

Using these optional parameters gives you an icon and manifest. A manifest allows you to specify run as normal, run elevated if admin, only run elevated.

/win32icon: Specifies a Win32 icon file (.ico) for the default Win32 resources.

/win32manifest: The provided file is embedded in the manifest section of the output PE.

In theory, I have UAC off so can't test, but put this text file on the desktop and call it vbs2exe.manifest, save as UTF-8.

The command line

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /t:winexe /win32manifest:"%userprofile%\desktop\VBS2Exe.manifest" "%userprofile%\desktop\VBS2Exe.vb"

The manifest

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
  <assembly xmlns="urn:schemas-microsoft-com:asm.v1" 
  manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0"

Hopefully it will now ONLY run as admin.

Give Access To a Host's Objects

Here's an example giving the vbscript access to a .NET object.

I had something similar, and here's (an edited) version of what I ended up using successfully:

ISNULL(CONVERT(VARCHAR(50),[column name goes here],[date style goes here] ),'')

Here's why this works: If you select a date which is NULL, it will show return NULL, though it is really stored as 01/01/1900. This is why an ISNULL on the date field, while you're working with any date data type will not treat this as a NULL, as it is technically not being stored as a NULL.

However, once you convert it to a new datatype, it will convert it as a NULL, and at that point, you're ISNULL will work as you expect it to work.

I hope this works out for you as well!

~Eli

Update, nearly one year later:

I had a similar situation, where I needed the output to be of the date data-type, and my aforementioned solution didn't work (it only works if you need it displayed as a date, not be of the date data type.

If you need it to be of the date data-type, there is a way around it, and this is to nest a REPLACE within an ISNULL, the following worked for me:

Select 
    ISNULL(
        REPLACE(
            [DATE COLUMN NAME],
            '1900-01-01',
            ''
        ),
    '') AS [MeaningfulAlias]

For Visual Basic, HTML and JScript and RDL Expression, the Window > New Window option mentioned in PaulB's answer is disabled. However an option can be changed in the Registry to enable the menu item.

All other languages do not restrict to a single code window so you can use PaulB's answer without editing the registry.

Enabling New Window in Windows Registry.^{[1] [2]}

1. Go to the following registry key. This example is for Basic (Visual Basic), but the key is also there for HTML, JScript and RDL Expression.

   • 64-bit OS: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Languages\Language Services\Basic
   • 32-bit OS: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\Languages\Language Services\Basic

2. Find the value Single Code Window Only and do one of the following:

   • Set it to 0
   • Rename the value
   • Delete the value (use caution!)

This will enable the "New Window" menu item, but it may still not be visible in the menu.

Adding Menu Item

To actually see the New Window menu item I had to add it back into the menu:

• Tools > Customize... > Commands > Add Command...
• Select 'Menu Bar' the select the 'Window' menu in the dropdown
• Add Command... > Window > New Window > OK

Restoring Registry Value
Copy-paste this to notepad, save as a .reg file and import the file into your registry to restore the initial setting.

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Languages\Language Services\Basic]
"Single Code Window Only"=dword:00000001

You will save yourself a heap of trouble (long term) if you store a ZIP Code as a character string, which it is, rather than a number, which it is not.

• for VB.NET: Environment.NewLine or vbCrLf or Constants.vbCrLf

You can do it using the same page on the action attribute: action='<yourpage>'

The onload property of the GlobalEventHandlers mixin is an event handler for the load event of a Window, XMLHttpRequest, element, etc., which fires when the resource has loaded.

So basically javascript already has onload method on window which get executed which page fully loaded including images...

You can do something:

var spinner = true;

window.onload = function() {
  //whatever you like to do now, for example hide the spinner in this case
  spinner = false;
};

I'm one of the maintainers of jackson-datatype-money, so take this answer with a grain of salt since I'm certainly biased. The module should cover your needs and it's pretty light-weight (no additional runtime dependencies). In addition it's mentioned in the Jackson docs, Spring docs and there were even some discussions already about how to integrate it into the official ecosystem of Jackson.

Actually the correct answer to this is to just add the schema to your document, like so

<packages xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">

...and you're done :)

If the XSD is not already cached and unavailable, you can add it as follows from the NuGet console

Install-Package NuGet.Manifest.Schema -Version 2.0.0

Once this is done, as noted in a comment below, you may want to move it from your current folder to the official schema folder that is found in

%VisualStudioPath%\Xml\Schemas

There is not really much difference in adding a css stylesheet in the head versus using the import functionality. Using @import is generally used for chaining stylesheets so that one can be easily extended. It could be used to easily swap different color layouts for example in conjunction with some general css definitions. I would say the main advantage / purpose is extensibility.

I agree with xbonez comment as well in that portability and maintainability are added benefits.

If somebody, who is looking for a solution in Swift, landed here, it would be:

myButton.isEnabled = false // disables
myButton.setTitle("myTitle", for: .normal) // sets text

Documentation: isEnabled, setTitle.

Older code:

myButton.enabled = false // disables
myButton.setTitle("myTitle", forState: UIControlState.Normal) // sets text

A slightly shorter solution, that only moves the item to the end, not anywhere is this:

l += [l.pop(0)]

For example:

>>> l = [1,2,3,4,5]
>>> l += [l.pop(0)]
>>> l
[2, 3, 4, 5, 1]

Many mobile devices have resolutions so high that it's hard to distinguish between them and much larger screens. There are two ways to deal with this problem:

Use the following HTML code to scale the pixels (grouping smaller pixels into groups the size of the unit pixel - 96dpi, so px units will have the same physical size on all screens). Note that this will affect the scale of pretty much everything in your website, but this is generally the way to go when making sites mobile-friendly.

<meta name="viewport" content="width=device-width, initial-scale=1">

Alternatively, measuring the screen width in @media queries using cm instead of px units can tell you if you're dealing with a physically small screen regardless of resolution.

Here is what I've used. Note, this cookie is passed in the open (http) and is therefore insecure. I don't use it for anything which requires security.

1. Site A generates a token and passes as a URL parameter to site B.
2. Site B takes the token and sets it as a session cookie.

You could probably add encryption/signatures to make this secure. Do your research on how to do that correctly.

Angular4

Instead of

    this.renderer.invokeElementMethod(
        this.fileInput.nativeElement, 'dispatchEvent', [event]);

use

    this.fileInput.nativeElement.dispatchEvent(event);

because invokeElementMethod won't be part of the renderer anymore.

Angular2

Use ViewChild with a template variable to get a reference to the file input, then use the Renderer to invoke dispatchEvent to fire the event:

import { Component, Renderer, ElementRef, ViewChild } from '@angular/core';
@Component({
  ...
  template: `
...
<input #fileInput type="file" id="imgFile" (click)="onChange($event)" >
...`
})
class MyComponent {
  @ViewChild('fileInput') fileInput:ElementRef;

  constructor(private renderer:Renderer) {}

  showImageBrowseDlg() {
    // from http://stackoverflow.com/a/32010791/217408
    let event = new MouseEvent('click', {bubbles: true});
    this.renderer.invokeElementMethod(
        this.fileInput.nativeElement, 'dispatchEvent', [event]);
  }
}

Update

Since direct DOM access isn't discouraged anymore by the Angular team this simpler code can be used as well

this.fileInput.nativeElement.click()

See also https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/dispatchEvent

merged = map(names(first), ~c(first[[.x]], second[[.x]])

You can use the datetime module for working with dates and times in Python. The strftime method allows you to produce string representation of dates and times with a format you specify.

>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'

Try to change #include <gl/glut.h> to #include "gl/glut.h" in Visual Studio 2013.

Anoher one

<form [formGroup]="myForm" novalidate>
    <input type="text" class="form-control" id="data" name="data"
           formControlName="input3" #item (input)="change(item.value)">
</form>
{{myForm.value |json}}

change(value:string)
  {
    let lastchar = value.substr(value.length - 1);
    if (!(new RegExp('[0-9]').test(lastchar)))
    {
      value=value.substr(0,value.length-1);
      this.myForm.controls["input3"].setValue(value);

    }
  }

if you use from driven template

  <input type="text" class="form-control" id="data" name="data"
       [(ngModel)]="data" #item (input)="change(item)">
   {{data}}

change(item:any)
  {
    let value=item.value;
    let lastchar = value.substr(value.length - 1);
    if (!(new RegExp('[0-9]').test(lastchar)))
    {
      value=value.substr(0,value.length-1);
      item.value=this.data=value;
    }
  }

Update As @BikashBishwokarma comment, this not work if you insert a character in middle. We can change the function by some like

  change(item:any)
  {
    let value=item.value;
    let pos=item.selectionStart;
    if (!(new RegExp('^[0-9]+$').test(value)))
    {
      item.value=this.data=value.replace(/[^0-9]+/g, '');
      item.selectionStart = item.selectionEnd = pos-1;
    }
  }

If you want to use valueChangeListener, you need to submit the form every time a new option is chosen. Something like this:

<p:selectOneMenu value="#{mymb.employee}" onchange="submit()"
                 valueChangeListener="#{mymb.handleChange}" >
    <f:selectItems value="#{mymb.employeesList}" var="emp"
                   itemLabel="#{emp.employeeName}" itemValue="#{emp.employeeID}" />
</p:selectOneMenu>

public void handleChange(ValueChangeEvent event){  
    System.out.println("New value: " + event.getNewValue());
}

Or else, if you want to use <p:ajax>, it should look like this:

<p:selectOneMenu value="#{mymb.employee}" >
    <p:ajax listener="#{mymb.handleChange}" />
    <f:selectItems value="#{mymb.employeesList}" var="emp"
                   itemLabel="#{emp.employeeName}" itemValue="#{emp.employeeID}" />
</p:selectOneMenu>

private String employeeID;

public void handleChange(){  
    System.out.println("New value: " + employee);
}

One thing to note is that in your example code, I saw that the value attribute of your <p:selectOneMenu> is #{mymb.employeesList} which is the same as the value of <f:selectItems>. The value of your <p:selectOneMenu> should be similar to my examples above which point to a single employee, not a list of employees.
