You need to go one level deeper in what you are retrieving.

Dim tbl As ListObject
Set tbl = ActiveSheet.ListObjects("MyTable")
MsgBox tbl.Range.Rows.Count
MsgBox tbl.HeaderRowRange.Rows.Count
MsgBox tbl.DataBodyRange.Rows.Count
Set tbl = Nothing

Because the compiler knows the binding at compile time. If you invoke a method on an interface, for example, then the compiler can't know and the binding is resolved at runtime because the actual object having a method invoked on it could possible be one of several. Therefore that is runtime or dynamic binding.

Your invocation is bound to the Animal class at compile time because you've specified the type. If you passed that variable into another method somewhere else, noone would know (apart from you because you wrote it) what actual class it would be. The only clue is the declared type of Animal.

this.print(false);

I tried this in Chrome, Firefox and IE. It works only in Firefox and IE, it uses the default printer (with default print settings) and only works when I render a PDF (I use Foxit Reader with Safe Reading Mode disabled). Chrome shows the print dialog, also the other browsers when I render an HTML page.

You only need a minimal change; single-quote the here-document delimiter after <<.

cat <<'EOF' >> brightup.sh

or equivalently backslash-escape it:

cat <<\EOF >>brightup.sh

Without quoting, the here document will undergo variable substitution, backticks will be evaluated, etc, like you discovered.

If you need to expand some, but not all, values, you need to individually escape the ones you want to prevent.

cat <<EOF >>brightup.sh
#!/bin/sh
# Created on $(date # : <<-- this will be evaluated before cat;)
echo "\$HOME will not be evaluated because it is backslash-escaped"
EOF

will produce

#!/bin/sh
# Created on Fri Feb 16 11:00:18 UTC 2018
echo "$HOME will not be evaluated because it is backslash-escaped"

As suggested by @fedorqui, here is the relevant section from man bash:

Here Documents

This type of redirection instructs the shell to read input from the current source until a line containing only delimiter (with no trailing blanks) is seen. All of the lines read up to that point are then used as the standard input for a command.

The format of here-documents is:

      <<[-]word
              here-document
      delimiter

No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. In the latter case, the character sequence \<newline> is ignored, and \ must be used to quote the characters \, $, and `.

class MyMath
{
    public dynamic Sum(dynamic x, dynamic y)
    {
        return (x+y);
    }
}

class Demo
{
    static void Main(string[] args)
    {
        MyMath d = new MyMath();
        Console.WriteLine(d.Sum(23.2, 32.2));
    }
}

They are exactly the same. When you use it be consistent. Use one of them in your database

Use sudo pico /etc/paths inside the terminal window and change the entries to the one you want to remove, then open a new terminal session.

You just need to use the shape: CircleBorder()

MaterialButton(

  color: Colors.blue,
  textColor: Colors.white,
  child: Icon(
    Icons.camera_alt,
    size: 24,

  padding: EdgeInsets.all(16),
  shape: CircleBorder(),
)

For Mac via homebrew:

brew tap petere/postgresql,

brew install <formula> (eg: brew install petere/postgresql/postgresql-9.6)

The requirements of the original question clearly couldn't benefit from string interpolation, as it seems like it's a runtime processing of arbitrary replacement keys.

However, if you just had to do string interpolation, you can use:

const str = `My name is ${replacements.name} and my age is ${replacements.age}.`

Note the backticks delimiting the string, they are required.

For an answer suiting the particular OP's requirement, you could use String.prototype.replace() for the replacements.

The following code will handle all matches and not touch ones without a replacement (so long as your replacement values are all strings, if not, see below).

var replacements = {"%NAME%":"Mike","%AGE%":"26","%EVENT%":"20"},
    str = 'My Name is %NAME% and my age is %AGE%.';

str = str.replace(/%\w+%/g, function(all) {
   return replacements[all] || all;
});

jsFiddle.

If some of your replacements are not strings, be sure they exists in the object first. If you have a format like the example, i.e. wrapped in percentage signs, you can use the in operator to achieve this.

jsFiddle.

However, if your format doesn't have a special format, i.e. any string, and your replacements object doesn't have a null prototype, use Object.prototype.hasOwnProperty(), unless you can guarantee that none of your potential replaced substrings will clash with property names on the prototype.

jsFiddle.

Otherwise, if your replacement string was 'hasOwnProperty', you would get a resultant messed up string.

jsFiddle.

As a side note, you should be called replacements an Object, not an Array.

I don't think you need the trailing slash in the URL entry. Ie, put this instead:

(r'^led-tv$', filter_by_led ),

This is assuming you have trailing slashes enabled, which is the default.

Take a look at this tutorial for how to use SQL inside VBA:

http://www.ehow.com/how_7148832_access-vba-query-results.html

For a query that won't return results, use (reference here):

DoCmd.RunSQL

For one that will, use (reference here):

Dim dBase As Database
dBase.OpenRecordset

I know it's an old question but I learned alot from the various answers but came up with my own solution as a function. This should dynamically add the parent folder as a prefix to all files that matches a certain pattern but only if it does not have that prefix already.

function Add-DirectoryPrefix($pattern) {
    # To debug, replace the Rename-Item with Select-Object
    Get-ChildItem -Path .\* -Filter $pattern -Recurse | 
        Where-Object {$_.Name -notlike ($_.Directory.Name + '*')} | 
        Rename-Item -NewName {$_.Directory.Name + '-' + $_.Name}
        # Select-Object -Property Directory,Name,@{Name = 'NewName'; Expression= {$_.Directory.Name + '-' + $_.Name}}
}

Using PNG is not such a good idea. Actually it's costly as far as performance is concerned. You can use drawable XML files, for example, Facebook's background.

This will help you to smooth and speed up your performance, and for the logo use .9 patch images.

Visibility change itself can be easy animated by overriding setVisibility method. Look at complete code:

public class SimpleViewAnimator extends FrameLayout
{
    private Animation inAnimation;
    private Animation outAnimation;

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

    public void setInAnimation(Animation inAnimation)
    {
        this.inAnimation = inAnimation;
    }

    public void setOutAnimation(Animation outAnimation)
    {
        this.outAnimation = outAnimation;
    }

    @Override
    public void setVisibility(int visibility)
    {
        if (getVisibility() != visibility)
        {
            if (visibility == VISIBLE)
            {
                if (inAnimation != null) startAnimation(inAnimation);
            }
            else if ((visibility == INVISIBLE) || (visibility == GONE))
            {
                if (outAnimation != null) startAnimation(outAnimation);
            }
        }

        super.setVisibility(visibility);
    }
}

The term "stack overrun (overflow)" is often used but a misnomer; attacks do not overflow the stack but buffers on the stack.

-- from lecture slides of Prof. Dr. Dieter Gollmann

I've been trying to do this in Jupyter Lab so thought it might be useful to post the answer here. You can find the shortcuts in settings and also add your own, where a full list of the possible shortcuts can be found here.

For example, I added my own shortcut to run all cells. In Jupyter Lab, under Settings > Advanced Settings, select Keyboard Shortcuts, then add the following code to 'User Overrides':

{
    "notebook:run-all-cells": {
      "command": "notebook:run-all-cells",
      "keys": [
        "Shift Backspace"
      ],
      "selector": ".jp-Notebook.jp-mod-editMode"
    }
}

Here, Shift + Backspace will run all cells in the notebook.

For people who use Bootstrap, textarea.form-control can lead to textarea sizing issues as well. Chrome and Firefox appear to use different heights with the following Bootstrap CSS:

textarea.form-conrtol{
    height:auto;
}

I implemented all the previous answers and still had one view that did not work correctly.

It turned out the name of the view I was having the problem with was named 'Recent'. Apparently this confused the Internet Explorer browser.

After I changed the view name (in the controller) to a different name (I chose to 'Recent5'), the solutions above started to work.

I had a similar issue and found that applying overflow: hidden; to both html and body solved my problem.

html,
body {
    overflow: hidden;
} 

For iOS 9, you may need to use this instead: (Thanks chaenu!)

html,
body {
    overflow: hidden;
    position: relative;
    height: 100%;
}

This answer is based on Yann's answer. It will set the aspect ratio for linear or log-log plots. I've used additional information from https://stackoverflow.com/a/16290035/2966723 to test if the axes are log-scale.

def forceAspect(ax,aspect=1):
    #aspect is width/height
    scale_str = ax.get_yaxis().get_scale()
    xmin,xmax = ax.get_xlim()
    ymin,ymax = ax.get_ylim()
    if scale_str=='linear':
        asp = abs((xmax-xmin)/(ymax-ymin))/aspect
    elif scale_str=='log':
        asp = abs((scipy.log(xmax)-scipy.log(xmin))/(scipy.log(ymax)-scipy.log(ymin)))/aspect
    ax.set_aspect(asp)

Obviously you can use any version of log you want, I've used scipy, but numpy or math should be fine.

You can also use sets:

a = numpy.array([10, 20, 30, 40, 50, 60, 70, 80, 90])
the_index_list = [2, 3, 6]

the_big_set = set(numpy.arange(len(a)))
the_small_set = set(the_index_list)
the_delta_row_list = list(the_big_set - the_small_set)

a = a[the_delta_row_list]

I have tried to rename the repository on the web page:

1. Click on the top of the right pages that it's your avatar.
2. you can look at the icon of setting, click it and then you can find the Repositories under the Personal setting.
3. click the Repositories and enter your directories of Repositories, choose the Repository that you want to rename.
4. Then you will enter the chosen Repository and you will find the icon of setting is added to the top line, just click it and enter the new name then click Rename.

Done, so easy.

You should use the = operator for string comparison:

Sourcesystem="ABC"

if [ "$Sourcesystem" = "XYZ" ]; then 
    echo "Sourcesystem Matched" 
else
    echo "Sourcesystem is NOT Matched $Sourcesystem"  
fi;

man test says that you use -z to match for empty strings.

You could try to do this with getcode() from urllib

>>> print urllib.urlopen("http://www.stackoverflow.com").getcode()
>>> 200

EDIT: For more modern python, i.e. python3, use:

import urllib.request
print(urllib.request.urlopen("http://www.stackoverflow.com").getcode())
>>> 200

Just add autofocus in first input or textarea.

<input type="text" name="name" id="xax" autofocus="autofocus" />

actually , this has turned out to be couple of javascript changes in the code. calling of javascript method with ; at the end. placing script tags in body instead of head. and interestingly even change the text displayed (please "click") to something that is not an event. so Please rate etc.

turned debugger on safari, it didnot give much information or even errors at times.

This post lead me to do this:

ActiveControl = null;

This allows me to capture all the keyboard input at the top level without other controls going nuts.

If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:

var items = (from x in parameters
                join y in myStrings on x.Source equals y
                select x)
            .ToList();

Try this:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    // You may decide to prompt to user else just kill.
    Process.GetCurrentProcess().Goose();
} 

Backup over ssh with password using temporary .pgpass credentials and push to S3:

#!/usr/bin/env bash
cd "$(dirname "$0")"

DB_HOST="*******.*********.us-west-2.rds.amazonaws.com"
DB_USER="*******"
SSH_HOST="[email protected]_domain.com"
BUCKET_PATH="bucket_name/backup"

if [ $# -ne 2 ]; then
    echo "Error: 2 arguments required"
    echo "Usage:"
    echo "  my-backup-script.sh <DB-name> <password>"
    echo "  <DB-name> = The name of the DB to backup"
    echo "  <password> = The DB password, which is also used for GPG encryption of the backup file"
    echo "Example:"
    echo "  my-backup-script.sh my_db my_password"
    exit 1
fi

DATABASE=$1
PASSWORD=$2

echo "set remote PG password .."
echo "$DB_HOST:5432:$DATABASE:$DB_USER:$PASSWORD" | ssh "$SSH_HOST" "cat > ~/.pgpass; chmod 0600 ~/.pgpass"
echo "backup over SSH and gzip the backup .."
ssh "$SSH_HOST" "pg_dump -U $DB_USER -h $DB_HOST -C --column-inserts $DATABASE" | gzip > ./tmp.gz
echo "unset remote PG password .."
echo "*********" | ssh "$SSH_HOST" "cat > ~/.pgpass"
echo "encrypt the backup .."
gpg --batch --passphrase "$PASSWORD" --cipher-algo AES256 --compression-algo BZIP2 -co "$DATABASE.sql.gz.gpg" ./tmp.gz

# Backing up to AWS obviously requires having your credentials to be set locally
# EC2 instances can use instance permissions to push files to S3
DATETIME=`date "+%Y%m%d-%H%M%S"`
aws s3 cp ./"$DATABASE.sql.gz.gpg" s3://"$BUCKET_PATH"/"$DATABASE"/db/"$DATETIME".sql.gz.gpg
# s3 is cheap, so don't worry about a little temporary duplication here
# "latest" is always good to have because it makes it easier for dev-ops to use
aws s3 cp ./"$DATABASE.sql.gz.gpg" s3://"$BUCKET_PATH"/"$DATABASE"/db/latest.sql.gz.gpg

echo "local clean-up .."
rm ./tmp.gz
rm "$DATABASE.sql.gz.gpg"

echo "-----------------------"
echo "To decrypt and extract:"
echo "-----------------------"
echo "gpg -d ./$DATABASE.sql.gz.gpg | gunzip > tmp.sql"
echo

Just substitute the first couple of config lines with whatever you need - obviously. For those not interested in the S3 backup part, take it out - obviously.

This script deletes the credentials in .pgpass afterward because in some environments, the default SSH user can sudo without a password, for example an EC2 instance with the ubuntu user, so using .pgpass with a different host account in order to secure those credential, might be pointless.

With TypeScript 2.9.+ you can simply import JSON files with typesafety and intellisense like this:

import colorsJson from '../colors.json'; // This import style requires "esModuleInterop", see "side notes"
console.log(colorsJson.primaryBright);

Make sure to add these settings in the compilerOptions section of your tsconfig.json (documentation):

"resolveJsonModule": true,
"esModuleInterop": true,

Side notes:

• Typescript 2.9.0 has a bug with this JSON feature, it was fixed with 2.9.2
• The esModuleInterop is only necessary for the default import of the colorsJson. If you leave it set to false then you have to import it with import * as colorsJson from '../colors.json'

This error happens when the resource is busy. Check if you have any referential constraints in the query. Or even the tables that you have mentioned in the query may be busy. They might be engaged with some other job which will be definitely listed in the following query results:

SELECT * FROM V$OPEN_CURSOR WHERE SID = --the id

Actually, I found a somewhat quirky way to do this. Add the protocol to your web.config, but inside a location element. Specify the webservice location as the path attribute, like so:

<location path="YourWebservice.asmx">
  <system.web>
    <webServices>
      <protocols>
        <add name="HttpGet"/>
        <add name="HttpPost"/>
      </protocols>
    </webServices>
  </system.web>
</location>

I found a way that seems to work better for me:

ssh-keygen -y -f <private key file>

That command will output the public key for the given private key, so then just compare the output to each *.pub file.

The stackLevel depends on depth you call this method. You can try from 0 to a large number to see what difference.

If stackLevel is legal, you will get string like java.lang.Thread.getStackTrace(Thread.java:1536)

public static String getCodeLocationInfo(int stackLevel) {
        StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace();
        if (stackLevel < 0 || stackLevel >= stackTraceElements.length) {
            return "Stack Level Out Of StackTrace Bounds";
        }
        StackTraceElement stackTraceElement = stackTraceElements[stackLevel];
        String fullClassName = stackTraceElement.getClassName();
        String methodName = stackTraceElement.getMethodName();
        String fileName = stackTraceElement.getFileName();
        int lineNumber = stackTraceElement.getLineNumber();

        return String.format("%s.%s(%s:%s)", fullClassName, methodName, fileName, lineNumber);
}

Add addToBackStack() to fragment transaction and then use below code for Implementing Back Navigation for Fragments

getSupportFragmentManager().addOnBackStackChangedListener(
    new FragmentManager.OnBackStackChangedListener() {
        public void onBackStackChanged() {
            // Update your UI here.
        }
    });

Using num_holes=None as the default is fine if you are going to have just __init__.

If you want multiple, independent "constructors", you can provide these as class methods. These are usually called factory methods. In this case you could have the default for num_holes be 0.

class Cheese(object):
    def __init__(self, num_holes=0):
        "defaults to a solid cheese"
        self.number_of_holes = num_holes

    @classmethod
    def random(cls):
        return cls(randint(0, 100))

    @classmethod
    def slightly_holey(cls):
        return cls(randint(0, 33))

    @classmethod
    def very_holey(cls):
        return cls(randint(66, 100))

Now create object like this:

gouda = Cheese()
emmentaler = Cheese.random()
leerdammer = Cheese.slightly_holey()

use def variable, when you want to compare any String. Use below code for that type of comparison.

def variable name = null

SQL query give you some return. Use function with return type def.

def functionname(def variablename){

return variable name

}

if ("$variable name" == "true"){

}

You have to set the default option by passing a third argument.

{{ Form::select('myselect', [1, 2], 2, ['id' => 'myselect']) }}

You can read the documentation here.

The key must be indexed to apply foreign key constraint. To do that follow the steps.

1. Open table structure. (2nd tab)
2. See the last column action where multiples action options are there. Click on Index, this will make the column indexed.
3. Open relation view and add foreign key constraint.

You will be able to assign DOCTOR_ID as foreign now.

If you are using "MVC 5" you may not see the file, and you should follow these steps: http://www.techjunkieblog.com/2015/05/aspnet-mvc-empty-project-adding.html

If you are using "ASP.NET 5" it has stopped using "bundling and minification" instead was replaced by gulp, bower, and npm. More information see https://jeffreyfritz.com/2015/05/where-did-my-asp-net-bundles-go-in-asp-net-5/

I got this problem when I directly downloaded code files from GitHub but it was showing this error, but my colleague told me to use "Git bash here" and use the command to Gitclone it. After doing so it works fine.

If you are a control freak like me, you may want to explicitly set all your font sizes:

import matplotlib.pyplot as plt

SMALL_SIZE = 8
MEDIUM_SIZE = 10
BIGGER_SIZE = 12

plt.rc('font', size=SMALL_SIZE)          # controls default text sizes
plt.rc('axes', titlesize=SMALL_SIZE)     # fontsize of the axes title
plt.rc('axes', labelsize=MEDIUM_SIZE)    # fontsize of the x and y labels
plt.rc('xtick', labelsize=SMALL_SIZE)    # fontsize of the tick labels
plt.rc('ytick', labelsize=SMALL_SIZE)    # fontsize of the tick labels
plt.rc('legend', fontsize=SMALL_SIZE)    # legend fontsize
plt.rc('figure', titlesize=BIGGER_SIZE)  # fontsize of the figure title

Note that you can also set the sizes calling the rc method on matplotlib:

import matplotlib

SMALL_SIZE = 8
matplotlib.rc('font', size=SMALL_SIZE)
matplotlib.rc('axes', titlesize=SMALL_SIZE)

# and so on ...

I think this would be a more simpler way of outputting your results.

Sorry for using my own data should be easy to replace .

$query = "SELECT * FROM category ";

$result = mysqli_query($connection, $query);


    while($row = mysqli_fetch_assoc($result))
    {
        $cat_id = $row['cat_id'];
        $cat_title = $row['cat_title'];

        echo $cat_id . " " . $cat_title  ."<br>";
    }

This would output :

• -ID Title
• -1 Gary
• -2 John
• -3 Michaels

You could also use =COUNTA(A1:A200) which requires no conditions.

From Google Support:

COUNTA counts all values in a dataset, including those which appear more than once and text values (including zero-length strings and whitespace). To count unique values, use COUNTUNIQUE.

Android doesn't have special code for sending and receiving HTTP, you can use standard Java code. I'd recommend using the Apache HTTP client, which comes with Android. Here's a snippet of code I used to send an HTTP POST.

I don't understand what sending the object in a variable named "jason" has to do with anything. If you're not sure what exactly the server wants, consider writing a test program to send various strings to the server until you know what format it needs to be in.

int TIMEOUT_MILLISEC = 10000;  // = 10 seconds
String postMessage="{}"; //HERE_YOUR_POST_STRING.
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient client = new DefaultHttpClient(httpParams);

HttpPost request = new HttpPost(serverUrl);
request.setEntity(new ByteArrayEntity(
    postMessage.toString().getBytes("UTF8")));
HttpResponse response = client.execute(request);

Just following the thread, can someone conclude which one is the most efficient way to check if an object exists in S3?

I think head_object might win as it just checks the metadata which is lighter than the actual object itself

Use Path.GetFullPath():

http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx

This should return the full path information.

you could use colgroups:

<table>
    <colgroup>
       <col class="visible_class"/>
       <col class="visible_class"/>
       <col class="invisible_class"/>  
    </colgroup>
    <thead>
        <tr><th class="col1">Header 1</th><th class="col2">Header 2</th><th class="col3">Header 3</th></tr>
    </thead>
    <tr><td>Column1</td><td>Column2</td><td>Column3</td></tr>
    <tr><td>Column1</td><td>Column2</td><td>Column3</td></tr>
    <tr><td>Column1</td><td>Column2</td><td>Column3</td></tr>
    <tr><td>Column1</td><td>Column2</td><td>Column3</td></tr>
</table>

your script then could change just the desire <col> class.

Integer is wrapper class and int is primitive data type.Always prefer using Integer in ArrayList.

Comparison sorts (i.e. ones based on comparing elements) cannot possibly be faster than n log n. It doesn't matter what the underlying data structure is. See Wikipedia.

Other kinds of sort that take advantage of there being lots of identical elements in the list (such as the counting sort), or some expected distribution of elements in the list, are faster, though I can't think of any that work particularly well on a linked list.

This will get you count:

get-alias | measure

You can work with the result as with object:

$m = get-alias | measure
$m.Count

And if you would like to have aliases in some variable also, you can use Tee-Object:

$m = get-alias | tee -Variable aliases | measure
$m.Count
$aliases

Some more info on Measure-Object cmdlet is on Technet.

Do not confuse it with Measure-Command cmdlet which is for time measuring. (again on Technet)

Another simple solution could be to use a structure or simple data class that contains the parameters as properties; that way you can have all the default values and behaviors set up ahead of time, passing the "parameter class" in as the single constructor parameter:

public class FooParams
{
    public int Size...
    protected myCustomStruct _ReasonForLife ...
}
public class Foo
{
    private FooParams _myParams;
    public Foo(FooParams myParams)
    {
          _myParams = myParams;
    }
}

This avoids the mess of multiple constructors (sometimes) and gives strong typing, default values, and other benefits not provided by a parameter array. It also makes it easy to carry forward since anything that inherits from Foo can still get to, or even add to, FooParams as needed. You still need to copy the constructor, but you always (most of the time) only (as a general rule) ever (at least, for now) need one constructor.

public class Bar : Foo
{
    public Bar(FooParams myParams) : base(myParams) {}
}

I really like the overloaded Initailize() and Class Factory Pattern approaches better, but sometimes you just need to have a smart constructor. Just a thought.

Use the xattr command. You can inspect the extended attributes:

$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms
com.apple.quarantine

and use the -d option to delete one extended attribute:

$ xattr -d com.apple.quarantine s.7z
$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms

you can also use the -c option to remove all extended attributes:

$ xattr -c s.7z
$ xattr s.7z

xattr -h will show you the command line options, and xattr has a man page.

for i in range(100):
try:
  #Your code here

This one worked for me.

The good part is we can make basic maths directly:

let nuts = 7_x000D_
_x000D_
more.innerHTML = `_x000D_
_x000D_
<h2>You collected ${nuts} nuts so far!_x000D_
_x000D_
<hr>_x000D_
_x000D_
Double it, get ${nuts + nuts} nuts!!_x000D_
_x000D_
`

<div id="more"></div>

It became really useful in a factory function:

function nuts(it){_x000D_
  return `_x000D_
    You have ${it} nuts! <br>_x000D_
    Cosinus of your nuts: ${Math.cos(it)} <br>_x000D_
    Triple nuts: ${3 * it} <br>_x000D_
    Your nuts encoded in BASE64:<br> ${btoa(it)}_x000D_
  `_x000D_
}_x000D_
_x000D_
nut.oninput = (function(){_x000D_
  out.innerHTML = nuts(nut.value)_x000D_
})

<h3>NUTS CALCULATOR_x000D_
<input type="number" id="nut">_x000D_
_x000D_
<div id="out"></div>

There is TKlerx's Android SQLite browser for Eclipse, and it's fully functional alongside Android Studio. I'll recommend it, because it is immensely practical.

To install it on Device Monitor, just place the JAR file in [Path to Android SDK folder]/sdk/tools/lib/monitor-[...]/plugins.

Here' an alternative

In Xcode 4 short cut to display and hide console is (command-shift-Y) , this will show the console and debugger below ur text edior in the same window.

I had given permissions I shouldn't have to write in some folders (especially /usr/bin/), and that caused the problem. I fixed it by opening Disk Utility and running 'Repair Disk Permissions' on the Macintosh HD disk.

NULL is not anything...it is unknown. NULL does not equal anything. That is why you have to use the magic phrase IS NULL instead of = NULL in your SQL queries

Using flexbox, this is easy to achieve.

Set the wrapper containing your 3 compartments to display: flex; and give it a height of 100% or 100vh. The height of the wrapper will fill the entire height, and the display: flex; will cause all children of this wrapper which has the appropriate flex-properties (for example flex:1;) to be controlled with the flexbox-magic.

Example markup:

<div class="wrapper">
    <header>I'm a 30px tall header</header>
    <main>I'm the main-content filling the void!</main>
    <footer>I'm a 30px tall footer</footer>
</div>

And CSS to accompany it:

.wrapper {
    height: 100vh;
    display: flex;

    /* Direction of the items, can be row or column */
    flex-direction: column;
}

header,
footer {
    height: 30px;
}

main {
    flex: 1;
}

Here's that code live on Codepen: http://codepen.io/enjikaka/pen/zxdYjX/left

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

I found the androidx.appcompat:appcompat:1.1.0 bug can also be fixed by simply calling getResources() in applyOverrideConfiguration()

@Override public void
applyOverrideConfiguration(Configuration cfgOverride)
{
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP &&
      Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
    // add this to fix androidx.appcompat:appcompat 1.1.0 bug
    // which happens on Android 6.x ~ 7.x
    getResources();
  }

  super.applyOverrideConfiguration(cfgOverride);
}

I think that you only have to replace SHA1 function with SHA256 function with tatk code from link in Your post

I just made a jQuery 3.2.1 bookmarklet with error-handling (only load if not already loaded, detect version if already loaded, error message if error while loading). Tested in Chrome 27. There is no reason to use the "old" jQuery 1.9.1 on Chrome browser since jQuery 2.0 is API-compatible with 1.9.

Just run the following in Chrome's developer console or drag & drop it in your bookmark bar:

javascript:((function(){if(typeof(jQuery)=="undefined"){window.jQuery="loading";var a=document.createElement("script");a.type="text/javascript";a.src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js";a.onload=function(){console.log("jQuery "+jQuery.fn.jquery+" loaded successfully.")};a.onerror=function(){delete jQuery;alert("Error while loading jQuery!")};document.getElementsByTagName("head")[0].appendChild(a)}else{if(typeof(jQuery)=="function"){alert("jQuery ("+jQuery.fn.jquery+") is already loaded!")}else{alert("jQuery is already loading...")}}})())

You can use Angular-Validator to do what you want. It's stupid simple to use.

It will:

• Only validate the fields on $dirty or on submit
• Prevent the form from being submitted if it is invalid
• Show custom error message after the field is $dirty or the form is submitted

See the demo

Example

<form angular-validator 
       angular-validator-submit="myFunction(myBeautifulForm)"
       name="myBeautifulForm">
       <!-- form fields here -->
    <button type="submit">Submit</button>
</form>

If the field does not pass the validator then the user will not be able to submit the form.

Check out angular-validator use cases and examples for more information.

Disclaimer: I am the author of Angular-Validator

System.IO.File.WriteAllText (@"D:\path.txt", contents);

• If the file exists, this overwrites it.
• If the file does not exist, this creates it.
• Please make sure you have appropriate privileges to write at the location, otherwise you will get an exception.

You need the whole python package, with a setup.py file in it.

A package named foo would be:

foo # the installable package
+-- foo
¦   +-- __init__.py
¦   +-- bar.py
+-- setup.py

And install from github like:

$ pip install git+ssh://[email protected]/myuser/foo.git
or
$ pip install git+https://github.com/myuser/foo.git@v123
or
$ pip install git+https://github.com/myuser/foo.git@newbranch

Consider a scenario where Test1, Test2 and Test3 are three classes. The Test3 class inherits Test2 and Test1 classes. If Test1 and Test2 classes have same method and you call it from child class object, there will be ambiguity to call method of Test1 or Test2 class but there is no such ambiguity for interface as in interface no implementation is there.

You can use array filter to remove the items by a specific condition on $v:

    return $v != 'some_value';
});

I faced a similar problem. In my case I had set _NT_SYMBOL_PATH to download from Microsoft Servers for use in WinDbg and it looks like when set, Visual Studio will use that with no way to ignore it. Removing that environment variable resolved my issue.

Works on both windows and linux. Should work on mac too if you are using pip.

Plain old Javascript:

<script type="text/javascript">

function changeHiddenInput (objDropDown)
{
    var objHidden = document.getElementById("hiddenInput");
    objHidden.value = objDropDown.value; 
}

</script>
<form>
    <select id="dropdown" name="dropdown" onchange="changeHiddenInput(this)">
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
    </select>

    <input type="hidden" name="hiddenInput" id="hiddenInput" value="" />
</form>

You can insert arbitrary PowerShell script code in a double-quoted string by using a subexpression, for example, $() like so:

"C:\temp\mybackup $(get-date -f yyyy-MM-dd).zip"

And if you are getting the path from somewhere else - already as a string:

$dirName  = [io.path]::GetDirectoryName($path)
$filename = [io.path]::GetFileNameWithoutExtension($path)
$ext      = [io.path]::GetExtension($path)
$newPath  = "$dirName\$filename $(get-date -f yyyy-MM-dd)$ext"

And if the path happens to be coming from the output of Get-ChildItem:

Get-ChildItem *.zip | Foreach {
  "$($_.DirectoryName)\$($_.BaseName) $(get-date -f yyyy-MM-dd)$($_.extension)"}

You need to recalculate width and height after first condition. Here is the code of entire script:

$(document).ready(function() {
    $('.story-small img').each(function() {
    var maxWidth = 100; // Max width for the image
    var maxHeight = 100;    // Max height for the image
    var ratio = 0;  // Used for aspect ratio
    var width = $(this).width();    // Current image width
    var height = $(this).height();  // Current image height

    // Check if the current width is larger than the max
    if(width > maxWidth){
        ratio = maxWidth / width;   // get ratio for scaling image
        $(this).css("width", maxWidth); // Set new width
        $(this).css("height", height * ratio);  // Scale height based on ratio
        height = height * ratio;    // Reset height to match scaled image
    }

    var width = $(this).width();    // Current image width
    var height = $(this).height();  // Current image height

    // Check if current height is larger than max
    if(height > maxHeight){
        ratio = maxHeight / height; // get ratio for scaling image
        $(this).css("height", maxHeight);   // Set new height
        $(this).css("width", width * ratio);    // Scale width based on ratio
        width = width * ratio;    // Reset width to match scaled image
    }
});

To answer the WHY in your question:

Because the equality operator can only be applied to simple variable types, such as floats, ints, or chars, and not to more sophisticated types, such as structures or arrays. To determine if two strings are equal, you must explicitly compare the two character strings character by character.

The two structs are different. When you initialize the first struct, about 40 bytes of memory are allocated. When you initialize the second struct, about 10 bytesof memory are allocated. (Actual amount is architecture dependent)

You can use the string literals (string constants) to initalize character arrays. This is why

person p = {"John", "Doe",30};

works in the first example.

You cannot assign (in the conventional sense) a string in C.

The string literals you have ("John") are loaded into memory when your code executes. When you initialize an array with one of these literals, then the string is copied into a new memory location. In your second example, you are merely copying the pointer to (location of) the string literal. Doing something like:

char* string = "Hello";
*string = 'C'

might cause compile or runtime errors (I am not sure.) It is a bad idea because you are modifying the literal string "Hello" which, for example on a microcontroler, could be located in read-only memory.

TextView textView = (TextView) spinActSubTask.getSelectedView().findViewById(R.id.tvProduct);

String subItem = textView.getText().toString();

There's no need for Prototype here: JavaScript has for..in loops. If you're not sure that no one messed with Object.prototype, check hasOwnProperty() as well, ie

for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
        doSomethingWith(obj[prop]);
}

The postition:absolute; tag positions the element relative to it's immediate parent. I noticed that even in the examples, there isn't room for scrolling, and when i tried it out, it didn't work. Therefore, to pull off the facebook floating menu, the position:fixed; tag should be used instead. It displaces/keeps the element at the given/specified location, and the rest of the page can scroll smoothly - even with the responsive ones.

Please see CSS postion attribute documentation when you can :)

Readable key names indexed by key code

There are relatively few key codes so I simply listed all the corresponding values in a static array so I could simply convert the number 65 into A using keyboardMap[65]

Not all key codes map to a printable character so some other identifiable string is returned.

You may need to modify the array to suit your needs and can simply return empty strings for all the characters you don't care to translate. The following array allows me to quickly and reliably determine which key was pressed in any environment. Enjoy!

I found that these instructions were not enough. I also had to search through the code files for models, controllers, and views as well as the AppStart files to change the namespace.

Since I was copying my project not just renaming it, I also had to go into the applicationhost.config for IIS express and recreate the bindings using different port numbers and change the physical directory as well.

While you really shouldn't use scanf() for this sort of thing, because there are much better calls such as gets() or getline(), it can be done:

#include <stdio.h>

char* scan_line(char* buffer, int buffer_size);

char* scan_line(char* buffer, int buffer_size) {
   char* p = buffer;
   int count = 0;
   do {
       char c;
       scanf("%c", &c); // scan a single character
       // break on end of line, string terminating NUL, or end of file
       if (c == '\r' || c == '\n' || c == 0 || c == EOF) {
           *p = 0;
           break;
       }
       *p++ = c; // add the valid character into the buffer
   } while (count < buffer_size - 1);  // don't overrun the buffer
   // ensure the string is null terminated
   buffer[buffer_size - 1] = 0;
   return buffer;
}

#define MAX_SCAN_LENGTH 1024

int main()
{
   char s[MAX_SCAN_LENGTH];
   printf("Enter a string: ");
   scan_line(s, MAX_SCAN_LENGTH);
   printf("got: \"%s\"\n\n", s);
   return 0;
}

For changing the text color in navbar you can use inline css as;

<a style="color: #3c6afc" href="#">

ssize_t is not included in the standard and isn't portable. size_t should be used when handling the size of objects (there's ptrdiff_t too, for pointer differences).

int i = 0;
int count = 1;
        while ('e'!= list[i] ) {
            i++;
            count++;
        }

        System.out.println(count);

If you are invoking foobarfunc with resolution scope operator (::), then you are calling it statically, e.g. on the class level instead of the instance level, thus you are using $this when not in object context. $this does not exist in class context.

If you enable E_STRICT, PHP will raise a Notice about this:

Strict Standards: 
Non-static method foobar::foobarfunc() should not be called statically

Do this instead

$fb = new foobar;
echo $fb->foobarfunc();

On a sidenote, I suggest not to use global inside your classes. If you need something from outside inside your class, pass it through the constructor. This is called Dependency Injection and it will make your code much more maintainable and less dependant on outside things.

Partitioning data is often used for distributing load horizontally, this has performance benefit, and helps in organizing data in a logical fashion. Example: if we are dealing with a large employee table and often run queries with WHERE clauses that restrict the results to a particular country or department . For a faster query response Hive table can be PARTITIONED BY (country STRING, DEPT STRING). Partitioning tables changes how Hive structures the data storage and Hive will now create subdirectories reflecting the partitioning structure like

.../employees/country=ABC/DEPT=XYZ.

If query limits for employee from country=ABC, it will only scan the contents of one directory country=ABC. This can dramatically improve query performance, but only if the partitioning scheme reflects common filtering. Partitioning feature is very useful in Hive, however, a design that creates too many partitions may optimize some queries, but be detrimental for other important queries. Other drawback is having too many partitions is the large number of Hadoop files and directories that are created unnecessarily and overhead to NameNode since it must keep all metadata for the file system in memory.

Bucketing is another technique for decomposing data sets into more manageable parts. For example, suppose a table using date as the top-level partition and employee_id as the second-level partition leads to too many small partitions. Instead, if we bucket the employee table and use employee_id as the bucketing column, the value of this column will be hashed by a user-defined number into buckets. Records with the same employee_id will always be stored in the same bucket. Assuming the number of employee_id is much greater than the number of buckets, each bucket will have many employee_id. While creating table you can specify like CLUSTERED BY (employee_id) INTO XX BUCKETS; where XX is the number of buckets . Bucketing has several advantages. The number of buckets is fixed so it does not fluctuate with data. If two tables are bucketed by employee_id, Hive can create a logically correct sampling. Bucketing also aids in doing efficient map-side joins etc.

There are 3 more methods where UNPIVOT (1) is the fastest by far, followed by Simulated Unpivot (3) which is much slower than (1) but still faster than (2)

you can, however, do something like this :

<div onclick="return function()
              {console.log('yaay, another onclick event!')}()" 
              @click="defaultFunction"></div>

yes, by using native onclick html event.

If you don't know how many columns you are going to have, the declaration

table-layout: fixed

along with not setting any column widths, would imply that browsers divide the total width evenly - no matter what.

That can also be the problem with this approach, if you use this, you should also consider how overflow is to be handled.

You can use any FTP client. I use winscp and it works just fine. In all these clients; you can specify the ssh secure key.

You can do:

list.OrderBy(x => Guid.NewGuid()).FirstOrDefault()

according to the mySQL reference manual this the syntax of using if and else statement :

IF search_condition THEN statement_list
[ELSEIF search_condition THEN statement_list] ...
[ELSE statement_list]
END IF

So regarding your query :

x = IF((action=2)&&(state=0),1,2);

or you can use

IF ((action=2)&&(state=0)) then 
state = 1;
ELSE 
state = 2;
END IF;

There is good example in this link : http://easysolutionweb.com/sql-pl-sql/how-to-use-if-and-else-in-mysql/

Yes. Or, rather, no.

Er, I mean, it doesn't matter. Use the one that makes sense for your particular project. PX and EM or both equally valid but will behave a bit different depending on your overall page's CSS architecture.

UPDATE:

To clarify, I'm stating that usually it likely doesn't matter which you use. At times, you may specifically want to choose one over the other. EMs are nice if you can start from scratch and want to use a base font size and make everything relative to that.

PXs are often needed when you're retrofitting a redesign onto an existing code base and need the specificity of px to prevent bad nesting issues.

    private void TurnOnAutocomplete()
    {
        textBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
        textBox.AutoCompleteSource = AutoCompleteSource.CustomSource;
        AutoCompleteStringCollection collection = new AutoCompleteStringCollection();
        string[] arrayOfWowrds = new string[];

        try
        {
            //Read in data Autocomplete list to a string[]
            string[] arrayOfWowrds = new string[];
        }
        catch (Exception err)
        {
            MessageBox.Show(err.Message, "File Missing", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }

        collection.AddRange(arrayOFWords);
        textBox.AutoCompleteCustomSource = collection;
    }

You only need to call this once after you have your data needed for the autocomplete list. Once bound it stays with the textBox. You do not need to or want to call it every time the text is changed in the textBox, that will kill your program.

Create new block formatting context

You can use display: flow-root on the parent element to prevent margin collapsing through the containing element as it creates new Block Formatting Context.

Changing the value of the overflow property to auto or using flexbox will have the same effect.

Adding on to Kalyoyan's answer, this subscription is tied to the router and will live until the page is fully refreshed. When subscribing to router events in a component, be sure to unsubscribe in ngOnDestroy:

import { OnDestroy } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router';
import { Subscription } from "rxjs/Rx";

class MyAppComponent implements OnDestroy {

  private subscription: Subscription;

  constructor(router: Router) {
    this.subscription = router.events.subscribe(s => {
      if (s instanceof NavigationEnd) {
        const tree = router.parseUrl(router.url);
        if (tree.fragment) {
          const element = document.querySelector("#" + tree.fragment);
          if (element) { element.scrollIntoView(element); }
        }
      }
    });
  }

  public ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

Although I am not sure if this is the result you expect, you can save your DataFrame in png by plotting the DataFrame with Seaborn Heatmap with annotations on, like this:

http://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.heatmap.html#seaborn.heatmap

It works right away with a Pandas Dataframe. You can look at this example: Efficiently ploting a table in csv format using Python

You might want to change the colormap so it displays a white background only.

Hope this helps.

df = df_try
for i in range(4):
   df = df.append(df_try)

# Here, we have df_try times 5

df = df.append(df)

# Here, we have df_try times 10

You can remove "JavaAppletPlugin.plugin" found in Spotlight or Finder, then re-install downloaded Java 8.

This will simply solve your problem.

Your description is a little bit strange because the GlassFish server can even start if port 1527 is occupied, because the Java Derby database is a separate java process. So one option could be to just ignore the message in case that the real GlassFish server is indeed starting correctly (NetBeans displays the output for the GlassFish server and the Derby server in different tabs).

Nevertheless you can try to disable starting the registered Derby server for your GlassFish instance.

Make sure that the Derby server is shut down, it can even still run if you have closed NetBeans. If you are not sure kill every java process via the task manager and restart NetBeans.

Right-click your GlassFish instance in the Services tab and choose Properties.

If instead the real problem is that either port 8080 or 443 (if you activated the HTTPS listener) is in use (which would really prevent GlassFish from starting), you have to find out which application is using this port (maybe Tomcat or something similar) and shut it down.

The error message

'Could not start GlassFish Server 4.1: HTTP or HTTPS listener port is occupied while server is not running'

just points a little bit more in this direction...

After upgrading to Xcode 12 I was still able to build for a real device, but not the simulator. The Podfile build was working only for the real device.

I deleted VALID_ARCHS under Build Settings > User-Defined and it worked! Bashing my head for some time before finding this.

I've personally always used boost.regex (although I don't have much need for regex in C++). Microsoft Labs has a regex library too, called GRETA: http://research.microsoft.com/projects/greta/. Apparently it's very fast and features a whole Perl 5 syntax. I haven't used it, but you may want to test it out.

A stardard-SQL version using boolean logic:

SELECT company_name
     , COUNT(action = 'EMAIL' OR NULL) AS "Email"
     , COUNT(action = 'PRINT' AND pagecount = 1 OR NULL) AS "Print 1 pages"
     , COUNT(action = 'PRINT' AND pagecount = 2 OR NULL) AS "Print 2 pages"
     , COUNT(action = 'PRINT' AND pagecount = 3 OR NULL) AS "Print 3 pages"
FROM   tbl
GROUP  BY company_name;

SQL Fiddle.

How?

TRUE OR NULL yields TRUE.
FALSE OR NULL yields NULL.
NULL OR NULL yields NULL.
And COUNT only counts non-null values. Voilá.

In Java 8 you can also use .stream().sorted():

myMap.keySet().stream().sorted().forEach(key -> {
        String value = myMap.get(key);

        System.out.println("key: " + key);
        System.out.println("value: " + value);
    }
);

Just remove COLUMN from ADD COLUMN

ALTER TABLE Employees
  ADD EmployeeID numeric NOT NULL IDENTITY (1, 1)

ALTER TABLE Employees ADD CONSTRAINT
        PK_Employees PRIMARY KEY CLUSTERED 
        (
          EmployeeID
        ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, 
        ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

When you are using JVM in 32-bit mode, the maximum heap size that can be allocated is 1280 MB. So, if you want to go beyond that, you need to invoke JVM in 64-mode.

You can use following:

$ java -d64 -Xms512m -Xmx4g HelloWorld

where,

• -d64: Will enable 64-bit JVM
• -Xms512m: Will set initial heap size as 512 MB
• -Xmx4g: Will set maximum heap size as 4 GB

You can tune in -Xms and -Xmx as per you requirements (YMMV)

A very good resource on JVM performance tuning, which might want to look into: http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html

To convert notebooks to PDF you first need to have nbconvert installed.

pip install nbconvert
# OR
conda install nbconvert

Next, if you aren't using Anaconda or haven't already, you must install pandoc either by following the instructions on their website or, on Linux, as follows:

sudo apt-get install pandoc

After that you need to have XeTex installed on your machine:

• Linux : TeX Live
• Mac : MacTex
• Windows : MikTex

You can now navigate to the folder that holds your IPython Notebook and run the following command:

jupyter nbconvert --to pdf MyNotebook.ipynb

for further reference, please check out this link.

If you want to click on all elements selected by some class, you can use this example (used on last.fm on the Loved tracks page to Unlove all).

var divs = document.querySelectorAll('.love-button.love-button--loved'); 

for (i = 0; i < divs.length; ++i) {
  divs[i].click();
};

With ES6 and Babel (cannot be run in the browser console directly)

[...document.querySelectorAll('.love-button.love-button--loved')]
   .forEach(div => { div.click(); })

$rootScope.$on( "$routeChangeStart", function(event, next, current) {
  //..do something
  //event.stopPropagation();  //if you don't want event to bubble up 
});

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

Although not secure, (no offense or anything), just stick the header function after you set the session variable

 while($row = mysql_fetch_assoc($result))
    {
            $_SESSION["user"] = $username;
    }
header('Location: /profile.php');

Several years too late:

Just for completeness I want to give yet another answer:

First, go to Excel-Options -> Formulas and enable R1C1 references. Then use

  =CELL("width", RC)

RC always refers the current Row, current Column, i.e. "this cell".

Rick Teachey's solution is basically a tweak to make the same possible in A1 reference style (see also GSerg's comment to Joey's answer and note his comment to Patrick McDonald's answer).

With jQuery

The event.which property normalizes event.keyCode and event.charCode. It is recommended to watch event.which for keyboard key input.

http://api.jquery.com/event.which/

jQuery('#input').on('keydown', function(e) {
    if( e.which == 8 || e.which == 46 ) return false;
});

this is you need and all people

   string date  = textBox1.Text;

        DateTime date2 = Convert.ToDateTime(date);
        var date3 = date2.Date;
        var D = date3.Day;
      var M =  date3.Month;         
      var y = date3.Year;
      string monthStr = M.ToString("00");
      string date4 = D.ToString() + "/" + monthStr.ToString() + "/" + y.ToString();


      textBox1.Text = date4;

You can also Try this:

var results= persons.GroupBy(n => new { n.PersonId, n.car})
                .Select(g => new {
                               g.Key.PersonId,
                               g.Key.car)}).ToList();

You can not change the height of the rounded rect border style. To set the height, just choose any border style other than rounded border in Xcode:

500 Internal Server Error is shown if your php code has fatal errors but error displaying is switched off. You may try this to see the error itself instead of 500 error page:

In your php file:

ini_set('display_errors', 1);

In .htaccess file:

php_flag display_errors 1

If you like me work from commandline the quick answer is executing

export ANT_OPTS=-Dbuild.sysclasspath=ignore

And then run your ant script again.

I had the exact same problem, this - "meta http-equiv="X-UA-Compatible" content="IE=7">" works great in IE8 and IE9, but not in IE10. There is a bug in the server browser definition files that shipped with .NET 2.0 and .NET 4, namely that they contain definitions for a certain range of browser versions. But the versions for some browsers (like IE 10) aren't within those ranges any more. Therefore, ASP.NET sees them as unknown browsers and defaults to a down-level definition, which has certain inconveniences, like that it does not support features like JavaScript.

My thanks to Scott Hanselman for this fix.

Here is the link -

http://www.hanselman.com/blog/BugAndFixASPNETFailsToDetectIE10CausingDoPostBackIsUndefinedJavaScriptErrorOrMaintainFF5ScrollbarPosition.aspx

This MS KP fix just adds missing files to the asp.net on your server. I installed it and rebooted my server and it now works perfectly. I would have thought that MS would have given this fix a wider distribution.

Rick

ES6 introduces computed property names, which allow you to do

var myObj = {[a]: b};

Note browser support is currently negligible.

In your while statement just replace mysql_fetch_row with mysql_fetch_array or mysql_fetch_assoc... whichever works...

You should use the optional argument indent.

header, output = client.request(twitterRequest, method="GET", body=None,
                            headers=None, force_auth_header=True)

# now write output to a file
twitterDataFile = open("twitterData.json", "w")
# magic happens here to make it pretty-printed
twitterDataFile.write(simplejson.dumps(simplejson.loads(output), indent=4, sort_keys=True))
twitterDataFile.close()

Suppose there are multiple static synchronized methods (m1, m2, m3, m4) in a class, and suppose one thread is accessing m1, then no other thread at the same time can access any other static synchronized methods.

I was having the same issue. I tried with the compatibility option, but in Windows 10 it doesn't show the compatibility option. The following steps solved the problem for me:

1. I made sure the account with which the task was running had the full access privileges on the file to be executed. (Executed the task and was still not running)
2. I man taskschd.msc as administrator
3. I added the account to run the task (whether was it logged or not)
4. I executed the task and now IT WORKED!

So somehow setting up the task in taskschd.msc as a regular user wasn't working, even though my account is an admin one.

Hope this helps anyone having the same issue

string[] lines = File.ReadLines("c:\\file.txt").ToArray();

Although one wonders why you'll want to do that when ReadAllLines works just fine.

Or perhaps you just want to enumerate with the return value of File.ReadLines:

var lines = File.ReadAllLines("c:\\file.txt");
foreach (var line in lines)
{
    Console.WriteLine("\t" + line);
}

There is no built-in functionality in VBS for that, however, you can use the FileSystemObject FileExists function for that :

Option Explicit
DIM fso    
Set fso = CreateObject("Scripting.FileSystemObject")

If (fso.FileExists("C:\Program Files\conf")) Then
  WScript.Echo("File exists!")
  WScript.Quit()
Else
  WScript.Echo("File does not exist!")
End If

WScript.Quit()

ulimit max memory size and virtual memory set to unlimited?

I have edited the code from one of the example here to use jquery. It's still not 100% jquery though. Any thoughts on the two different versions, like what are the pros and cons of each?

function column_sort() {
    getCellValue = (tr, idx) => $(tr).find('td').eq( idx ).text();

    comparer = (idx, asc) => (a, b) => ((v1, v2) => 
        v1 !== '' && v2 !== '' && !isNaN(v1) && !isNaN(v2) ? v1 - v2 : v1.toString().localeCompare(v2)
        )(getCellValue(asc ? a : b, idx), getCellValue(asc ? b : a, idx));
    
    table = $(this).closest('table')[0];
    tbody = $(table).find('tbody')[0];

    elm = $(this)[0];
    children = elm.parentNode.children;
    Array.from(tbody.querySelectorAll('tr')).sort( comparer(
        Array.from(children).indexOf(elm), table.asc = !table.asc))
        .forEach(tr => tbody.appendChild(tr) );
}

table.find('thead th').on('click', column_sort);

If you want to make your code work as above, the function printInformation() needs to be declared and implemented as a static function.

If, on the other hand, it is supposed to print information about a specific object, you need to create the object first.

i think the simplest way will be to add this css and it will work perfectly.

embed, object, iframe{max-width: 100%;}

You need the :not() selector:

$('div[class^="first-"]:not(.first-bar)')

or, alternatively, the .not() method:

$('div[class^="first-"]').not('.first-bar');

var assoc_pagine = new Array();
assoc_pagine["home"]=0;

Don't use an Array for this. Arrays are for numerically-indexed lists. Just use a plain Object ({}).

What you are thinking of with the 'undefined' string is probably this:

if (typeof assoc_pagine[key]!=='undefined')

This is (more or less) the same as saying

if (assoc_pagine[key]!==undefined)

However, either way this is a bit ugly. You're dereferencing a key that may not exist (which would be an error in any more sensible language), and relying on JavaScript's weird hack of giving you the special undefined value for non-existent properties.

This also doesn't quite tell you if the property really wasn't there, or if it was there but explicitly set to the undefined value.

This is a more explicit, readable and IMO all-round better approach:

if (key in assoc_pagine)

Not sure where you get your legends from but:

Submit button with <button>

As with:

<button type="submit">(html content)</button>

IE6 will submit all text for this button between the tags, other browsers will only submit the value. Using <button> gives you more layout freedom over the design of the button. In all its intents and purposes, it seemed excellent at first, but various browser quirks make it hard to use at times.

In your example, IE6 will send text to the server, while most other browsers will send nothing. To make it cross-browser compatible, use <button type="submit" value="text">text</button>. Better yet: don't use the value, because if you add HTML it becomes rather tricky what is received on server side. Instead, if you must send an extra value, use a hidden field.

Button with <input>

As with:

<input type="button" />

By default, this does next to nothing. It will not even submit your form. You can only place text on the button and give it a size and a border by means of CSS. Its original (and current) intent was to execute a script without the need to submit the form to the server.

Normal submit button with <input>

As with:

<input type="submit" />

Like the former, but actually submits the surrounding form.

Image submit button with <input>

As with:

<input type="image" />

Like the former (submit), it will also submit a form, but you can use any image. This used to be the preferred way to use images as buttons when a form needed submitting. For more control, <button> is now used. This can also be used for server side image maps but that's a rarity these days. When you use the usemap-attribute and (with or without that attribute), the browser will send the mouse-pointer X/Y coordinates to the server (more precisely, the mouse-pointer location inside the button of the moment you click it). If you just ignore these extras, it is nothing more than a submit button disguised as an image.

There are some subtle differences between browsers, but all will submit the value-attribute, except for the <button> tag as explained above.

take mongodb backup for particular db and delete 7 days old backup using bin sh command :-

#!/bin/bash

MONGO_DATABASE="nexgtv_16"
APP_NAME="test"
MONGO_HOST="127.0.0.1"
MONGO_PORT="27017"
TIMESTAMP=`date +%F-%H%M`
MONGODUMP_PATH="/usr/bin/mongodump"
BACKUPS_DIR="/home/mongodbbackups/backups/$APP_NAME"
BACKUP_NAME="$APP_NAME-$TIMESTAMP"
$MONGODUMP_PATH -d $MONGO_DATABASE
mkdir -p $BACKUPS_DIR
mv dump $BACKUP_NAME
tar -zcvf $BACKUPS_DIR/$BACKUP_NAME.tgz $BACKUP_NAME
rm -rf $BACKUP_NAME
find /home/mongodbbackups/backups/test/ -mindepth 1 -mtime +7 -delete

You can use aggregate to calculate the means:

means<-aggregate(df,by=list(df$gender),mean)
Group.1      tea     coke     beer    water gender
1       1 87.70171 27.24834 24.27099 37.24007      1
2       2 24.73330 25.27344 25.64657 24.34669      2

Get rid of the Group.1 column

means<-means[,2:length(means)]

Then you have reformat the data to be in long format:

library(reshape2)
means.long<-melt(means,id.vars="gender")
  gender variable    value
1      1      tea 87.70171
2      2      tea 24.73330
3      1     coke 27.24834
4      2     coke 25.27344
5      1     beer 24.27099
6      2     beer 25.64657
7      1    water 37.24007

Finally, you can use ggplot2 to create your plot:

library(ggplot2)
ggplot(means.long,aes(x=variable,y=value,fill=factor(gender)))+
  geom_bar(stat="identity",position="dodge")+
  scale_fill_discrete(name="Gender",
                      breaks=c(1, 2),
                      labels=c("Male", "Female"))+
  xlab("Beverage")+ylab("Mean Percentage")

I had to do this to get the result that I wanted:

<td style="font-size:3px; float:left; height:5px; vertical-align:middle;" colspan="7"><div style="font-size:3px; height:5px; vertical-align:middle;"><b><hr></b></div></td>

It refused to work with only the cell or the div and needed both.

window.opener.$("#serverMsg")

You have diferent ways to achieve this, here is an example:

import myimage from './...' // wherever is it.

in your img tag just put this into src:

<img src={myimage}...>

You can also check official docs here: https://facebook.github.io/react-native/docs/image.html

mysqldb is a module for Python that doesn't come pre-installed or with Django. You can download mysqldb here.

Well, OP didn't say server or client side, so i will just leave this here in case someone like me is looking for client side:

http://skulpt.org/using.html

Skulpt is a implementation of Python to run at client side. Very interesting, no plugin required, just a simple JS.

Check you build.gradle (Module: your app).

All com.google.android.gms libraries must use the exact same version specification (mixing versions can lead to runtime crashes).

For example: If you have com.google.firebase:firebase-ads:9.6.1 and com.google.android.gms:play-services-basement:10.0.1

You have to change the firebase version to: 10.0.1

I was facing this error in Xamarin. This was due to some files that were present in drawable-v21 folder. So I copied those files (probably icon files) to the drawable folder and the error was gone.

For arrays you can use: Array.FindIndex<T>:

int keyIndex = Array.FindIndex(words, w => w.IsKey);

For lists you can use List<T>.FindIndex:

int keyIndex = words.FindIndex(w => w.IsKey);

You can also write a generic extension method that works for any Enumerable<T>:

///<summary>Finds the index of the first item matching an expression in an enumerable.</summary>
///<param name="items">The enumerable to search.</param>
///<param name="predicate">The expression to test the items against.</param>
///<returns>The index of the first matching item, or -1 if no items match.</returns>
public static int FindIndex<T>(this IEnumerable<T> items, Func<T, bool> predicate) {
    if (items == null) throw new ArgumentNullException("items");
    if (predicate == null) throw new ArgumentNullException("predicate");

    int retVal = 0;
    foreach (var item in items) {
        if (predicate(item)) return retVal;
        retVal++;
    }
    return -1;
}

And you can use LINQ as well:

int keyIndex = words
    .Select((v, i) => new {Word = v, Index = i})
    .FirstOrDefault(x => x.Word.IsKey)?.Index ?? -1;

AFAIK from Eclipse 3.5 M4 on the formatter has an option "Never Join Lines" which preserves user lines breaks. Maybe that does what you want.

Else there is this ugly hack

String query = //
    "SELECT FOO, BAR, BAZ" + //
    "  FROM ABC"           + //
    " WHERE BAR > 4";

Sometimes you can refactor your @Component to use constructor or setter based injection to setup your testcase (you can and still rely on @Autowired). Now, you can create your test entirely without a mocking framework by implementing test stubs instead (e.g. Martin Fowler's MailServiceStub):

@Component
public class MyLauncher {

    private MyService myService;

    @Autowired
    MyLauncher(MyService myService) {
        this.myService = myService;
    }

    // other methods
}

public class MyServiceStub implements MyService {
    // ...
}

public class MyLauncherTest
    private MyLauncher myLauncher;
    private MyServiceStub myServiceStub;

    @Before
    public void setUp() {
        myServiceStub = new MyServiceStub();
        myLauncher = new MyLauncher(myServiceStub);
    }

    @Test
    public void someTest() {

    }
}

This technique especially useful if the test and the class under test is located in the same package because then you can use the default, package-private access modifier to prevent other classes from accessing it. Note that you can still have your production code in src/main/java but your tests in src/main/test directories.

If you like Mockito then you will appreciate the MockitoJUnitRunner. It allows you to do "magic" things like @Manuel showed you:

@RunWith(MockitoJUnitRunner.class)
public class MyLauncherTest
    @InjectMocks
    private MyLauncher myLauncher; // no need to call the constructor

    @Mock
    private MyService myService;

    @Test
    public void someTest() {

    }
}

Alternatively, you can use the default JUnit runner and call the MockitoAnnotations.initMocks() in a setUp() method to let Mockito initialize the annotated values. You can find more information in the javadoc of @InjectMocks and in a blog post that I have written.

I wrote a regex to help find and replace "&" within an INSERT, I hope that this helps someone.

The trick was to make sure that the "&" was with other text.

Find “(\'[^\']*(?=\&))(\&)([^\']*\')”

Replace “$1' || chr(38) || '$3”

The solution is:

 $('body').scroll(function(e){
    console.log(e);
});

I know my answer is late to the party. But the way i solved is bit different than all the answers.

I had a situation, i need to clone a row in a table except few columns. Those few will have new values. This process should support automatically for future changes to the table. This implies, clone the record without specifying any column names.

My approach is to,

1. Query Sys.Columns to get the full list of columns for the table and include the names of columns to skip in where clause.
2. Convert that in to CSV as column names.
3. Build Select ... Insert into script based on this.

declare @columnsToCopyValues varchar(max), @query varchar(max)
SET @columnsToCopyValues = ''

--Get all the columns execpt Identity columns and Other columns to be excluded. Say IndentityColumn, Column1, Column2
Select @columnsToCopyValues = @columnsToCopyValues + [name] + ', ' from sys.columns c where c.object_id = OBJECT_ID('YourTableName') and name not in ('IndentityColumn','Column1','Column2')
Select @columnsToCopyValues = SUBSTRING(@columnsToCopyValues, 0, LEN(@columnsToCopyValues))
print @columnsToCopyValues
Select @query = CONCAT('insert into YourTableName (',@columnsToCopyValues,', Column1, Column2) select ', @columnsToCopyValues, ',''Value1'',''Value2'',', ' from YourTableName where IndentityColumn =''' , @searchVariable,'''')
print @query
exec (@query)

You can use attrchange jQuery plugin. The main function of the plugin is to bind a listener function on attribute change of HTML elements.

Code sample:

$("#myDiv").attrchange({
    trackValues: true, // set to true so that the event object is updated with old & new values
    callback: function(evnt) {
        if(evnt.attributeName == "display") { // which attribute you want to watch for changes
            if(evnt.newValue.search(/inline/i) == -1) {

                // your code to execute goes here...
            }
        }
    }
});

Depending how you want to implement it (if there was a specific location you wanted the scripts) you could implement a @section within your _Layout which would enable you to add additional scripts from the view itself, while still retaining structure. e.g.

_Layout

<!DOCTYPE html>
<html>
  <head>
    <title>...</title>
    <script src="@Url.Content("~/Scripts/jquery.min.js")"></script>
    @RenderSection("Scripts",false/*required*/)
  </head>
  <body>
    @RenderBody()
  </body>
</html>

View

@model MyNamespace.ViewModels.WhateverViewModel
@section Scripts
{
  <script src="@Url.Content("~/Scripts/jqueryFoo.js")"></script>
}

Otherwise, what you have is fine. If you don't mind it being "inline" with the view that was output, you can place the <script> declaration within the view.

subprocess.call expects the same arguments as subprocess.Popen - that is a list of strings (the argv in C) rather than a single string.

It's quite possible that your child process attempted to run "s" with the parameters "o", "m", "e", ...

you can use the remove() function of the example below and build table again with table head, and table body

$("#table_id  thead").remove();
$("#table_id  tbody").remove();

This is a "nicer solution" and quite simple

if(new string[] { "A", "B", ... }.Any(s=>myString.Contains(s)))

Just a quick note. Be wary of using for..in if you use a library (jQuery, Prototype, etc.), as most of them add methods to created Objects (including dictionaries).

This will mean that when you loop over them, method names will appear as keys. If you are using a library, look at the documentation and look for an enumerable section, where you will find the right methods for iteration of your objects.

Just adding to the solutions already suggested. Assumes same height, no resizing.

import sys
import glob
from PIL import Image
Image.MAX_IMAGE_PIXELS = 100000000  # For PIL Image error when handling very large images

imgs    = [ Image.open(i) for i in list_im ]

widths, heights = zip(*(i.size for i in imgs))
total_width = sum(widths)
max_height = max(heights)

new_im = Image.new('RGB', (total_width, max_height))

# Place first image
new_im.paste(imgs[0],(0,0))

# Iteratively append images in list horizontally
hoffset=0
for i in range(1,len(imgs),1):
    **hoffset=imgs[i-1].size[0]+hoffset  # update offset**
    new_im.paste(imgs[i],**(hoffset,0)**)

new_im.save('output_horizontal_montage.jpg')

A lot of good solutions and valuable commentaries by known experts from JS community on the topic could be found here. It could be an indicator that it's not that trivial problem as it may seem. I think this is why it could be the source of doubts and uncertainty on the issue.

Fundamental problem here is that in React you're only allowed to mount component to its parent, which is not always the desired behavior. But how to address this issue?

I propose the solution, addressed to fix this issue. More detailed problem definition, src and examples can be found here: https://github.com/fckt/react-layer-stack#rationale

Rationale

react/react-dom comes comes with 2 basic assumptions/ideas:

• every UI is hierarchical naturally. This why we have the idea of components which wrap each other
• react-dom mounts (physically) child component to its parent DOM node by default

The problem is that sometimes the second property isn't what you want in your case. Sometimes you want to mount your component into different physical DOM node and hold logical connection between parent and child at the same time.

Canonical example is Tooltip-like component: at some point of development process you could find that you need to add some description for your UI element: it'll render in fixed layer and should know its coordinates (which are that UI element coord or mouse coords) and at the same time it needs information whether it needs to be shown right now or not, its content and some context from parent components. This example shows that sometimes logical hierarchy isn't match with the physical DOM hierarchy.

Take a look at https://github.com/fckt/react-layer-stack/blob/master/README.md#real-world-usage-example to see the concrete example which is answer to your question:

import { Layer, LayerContext } from 'react-layer-stack'
// ... for each `object` in array of `objects`
  const modalId = 'DeleteObjectConfirmation' + objects[rowIndex].id
  return (
    <Cell {...props}>
        // the layer definition. The content will show up in the LayerStackMountPoint when `show(modalId)` be fired in LayerContext
        <Layer use={[objects[rowIndex], rowIndex]} id={modalId}> {({
            hideMe, // alias for `hide(modalId)`
            index } // useful to know to set zIndex, for example
            , e) => // access to the arguments (click event data in this example)
          <Modal onClick={ hideMe } zIndex={(index + 1) * 1000}>
            <ConfirmationDialog
              title={ 'Delete' }
              message={ "You're about to delete to " + '"' + objects[rowIndex].name + '"' }
              confirmButton={ <Button type="primary">DELETE</Button> }
              onConfirm={ this.handleDeleteObject.bind(this, objects[rowIndex].name, hideMe) } // hide after confirmation
              close={ hideMe } />
          </Modal> }
        </Layer>

        // this is the toggle for Layer with `id === modalId` can be defined everywhere in the components tree
        <LayerContext id={ modalId }> {({showMe}) => // showMe is alias for `show(modalId)`
          <div style={styles.iconOverlay} onClick={ (e) => showMe(e) }> // additional arguments can be passed (like event)
            <Icon type="trash" />
          </div> }
        </LayerContext>
    </Cell>)
// ...

Strictly speaking, the difference between Database and Schema is inexisting in MySql.

However, this is not the case in other database engines such as SQL Server. In SQL server:,

Every table belongs to a grouping of objects in the database called database schema. It's a container or namespace (Querying Microsoft SQL Server 2012)

By default, all the tables in SQL Server belong to a default schema called dbo. When you query a table that hasn't been allocated to any particular schema, you can do something like:

SELECT *
FROM your_table

which is equivalent to:

SELECT *
FROM dbo.your_table

Now, SQL server allows the creation of different schema, which gives you the possibility of grouping tables that share a similar purpose. That helps to organize the database.

For example, you can create an schema called sales, with tables such as invoices, creditorders (and any other related with sales), and another schema called lookup, with tables such as countries, currencies, subscriptiontypes (and any other table used as look up table).

The tables that are allocated to a specific domain are displayed in SQL Server Studio Manager with the schema name prepended to the table name (exactly the same as the tables that belong to the default dbo schema).

There are special schemas in SQL Server. To quote the same book:

There are several built-in database schemas, and they can't be dropped or altered:

1) dbo, the default schema.

2) guest contains objects available to a guest user ("guest user" is a special role in SQL Server lingo, with some default and highly restricted permissions). Rarely used.

3) INFORMATION_SCHEMA, used by the Information Schema Views

4) sys, reserved for SQL Server internal use exclusively

Schemas are not only for grouping. It is actually possible to give different permissions for each schema to different users, as described MSDN.

Doing this way, the schema lookup mentioned above could be made available to any standard user in the database (e.g. SELECT permissions only), whereas a table called supplierbankaccountdetails may be allocated in a different schema called financial, and to give only access to the users in the group accounts (just an example, you get the idea).

Finally, and quoting the same book again:

It isn't the same Database Schema and Table Schema. The former is the namespace of a table, whereas the latter refers to the table definition

To still be able to scroll this worked for me

if (e.changedTouches.length > 1) e.preventDefault();

Paul Dardeau answer is perfect, the only thing is, what if all the files inside those folders are not PDF files and you want to grab it all no matter the extension. Well just change it to

find . -name "*.*" -type f -exec cp {} ./pdfsfolder \;

Just to sum up!

In Swift 4.2 and Xcode 10.1

let string:String = "789"
let intValue:Int = Int(string)!
print(intValue)

let integerValue:Int = 789
let stringValue:String = String(integerValue)
    //OR
//let stringValue:String = "\(integerValue)"
print(stringValue)

    string & replace(string & subj, string old, string neu)
    {
        size_t uiui = subj.find(old);
        if (uiui != string::npos)
        {
           subj.erase(uiui, old.size());
           subj.insert(uiui, neu);
        }
        return subj;
    }

I think this fits your requirement with few code!

SELECT A.ABC_ID, A.VAL FROM A WHERE NOT EXISTS 
   (SELECT * FROM B WHERE B.ABC_ID = A.ABC_ID AND B.VAL = A.VAL)

or

SELECT A.ABC_ID, A.VAL FROM A WHERE VAL NOT IN 
    (SELECT VAL FROM B WHERE B.ABC_ID = A.ABC_ID)

or

SELECT A.ABC_ID, A.VAL LEFT OUTER JOIN B 
    ON A.ABC_ID = B.ABC_ID AND A.VAL = B.VAL FROM A WHERE B.VAL IS NULL

Please note that these queries do not require that ABC_ID be in table B at all. I think that does what you want.

Application.Exit() kills your application but there are some instances that it won't close the application.

End is better than Application.Exit().

If you set a breakpoint, you can paste this into the debugger to print the view hierarchy:

po [[UIWindow keyWindow] recursiveDescription]

You should be able to find your view's parent somewhere in that mess :)

"put" has been deprecated, refrain from using it, use .of instead

ImmutableMap<String, String> myMap = ImmutableMap.of(
    "city1", "Seattle",
    "city2", "Delhi"
);

In your stylesheet:

div#content.myClass

Edit: These might help, too:

div#content.myClass.aSecondClass.aThirdClass /* Won't work in IE6, but valid */
div.firstClass.secondClass /* ditto */

and, per your example:

div#content.sectionA

Edit, 4 years later: Since this is super old and people keep finding it: don't use the tagNames in your selectors. #content.myClass is faster than div#content.myClass because the tagName adds a filtering step that you don't need. Use tagNames in selectors only where you must!

You can find information and a little description of the MBDB/MBDX format here:

http://code.google.com/p/iphonebackupbrowser/

This is my application to browse the backup files. I have tried to document the format of the new files that come with iTunes 9.2.

On Ubuntu 14.04, I found two parts to solving the problem:

1. Remove /jre from the environment variable. For me: export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/
2. Install the JDK as well as the JRE: sudo apt-get install default-jdk

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)

To quote a quote:

The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery).

.data() - jQuery Documentiation

Note that this (Frankly odd) limitation is only withheld to the use of .data().

The solution? Use .attr instead.

Of course, several of you may feel uncomfortable with not using it's dedicated method. Consider the following scenario:

• The 'standard' is updated so that the data- portion of custom attributes is no longer required/is replaced

Common sense - Why would they change an already established attribute like that? Just imagine class begin renamed to group and id to identifier. The Internet would break.

And even then, Javascript itself has the ability to fix this - And of course, despite it's infamous incompatibility with HTML, REGEX (And a variety of similar methods) could rapidly rename your attributes to this new-mythical 'standard'.

TL;DR

alert($(targetField).attr("data-helptext"));

You can use both with relatively few issues. Twitter Bootstrap uses jQuery 1.7.1 (as of this writing), and I can't think of any reasons why you cannot integrate additional Jquery UI components into your HTML templates.

I've been using a combination of HTML5 Boilerplate & Twitter Bootstrap built at Initializr.com. This combines two awesome starter templates into one great starter project. Check out the details at http://html5boilerplate.com/ and http://www.initializr.com/ Or to get started right away, go to http://www.initializr.com/, click the "Bootstrap 2" button, and click "Download It". This will give you all the js and css you need to get started.

And don't be scared off by HTML5 and CSS3. Initializr and HTML5 Boilerplate include polyfills and IE specific code that will allow all features to work in IE 6, 7 8, and 9.

The use of LESS in Twitter Bootstrap is also optional. They use LESS to compile all the CSS that is used by Bootstrap, but if you just want to override or add your own styles, they provide an empty css file for that purpose.

There is also a blank js file (script.js) for you to add custom code. This is where you would add your handlers or selectors for additional jQueryUI components.

This can also be done with a timeout:

# Ping until timeout or 1 successful packet
ping -w (timeout) -c 1

Swift 4.2

In Swift 4.2 the name of table is a little changed.

    func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let view = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 18))
        let label = UILabel(frame: CGRect(x: 10, y: 5, width: tableView.frame.size.width, height: 18))
        label.font = UIFont.systemFont(ofSize: 14)
        label.text = list.objectAtIndex(section) as! String
        view.addSubview(label)
        view.backgroundColor = UIColor.gray // Set your background color

        return view
    }

Dynamic resources can only be used when property being set is on object which is derived from dependency object or freezable where as static resources can be used anywhere. You can abstract away entire control using static resources.

Static resources are used under following circumstances:

1. When reaction resource changes at runtime is not required.
2. If you need a good performance with lots of resources.
3. While referencing resources within the same dictionary.

Dynamic resources:

1. Value of property or style setter theme is not known until runtime
   • This include system, aplication, theme based settings
   • This also includes forward references.
2. Referencing large resources that may not load when page, windows, usercontrol loads.
3. Referencing theme styles in a custom control.

Firstly, in your react project go to your package.json and adjust this line line of code to match your destination domain address + folder:

"homepage": "https://yourwebsite.com/your_folder_name/",

Secondly, go to terminal in your react project and type:

npm run build

Now, take all files from that newly created build folder and upload them into your_folder_name, with filezilla in subfolder like this:

public_html/your_folder_name

Check in the browser!

you can use this module -> https://github.com/jiahut/ng.lodash

this is for lodash so does underscore

For me none of the solutions provided worked.

This should be your last resort: -> Open .iml file of your project change the LANGUAGE_LEVEL to JDK_1_8 or whatever version you wish. -> If this didn't help, you should grep "JDK" in your project root directory and find the file which contains version setting and set it to your preferred version.

Check out this post, was very helpful for myself. Download the code sample:

http://www.codeproject.com/Articles/335909/Embedding-a-Console-in-a-C-Application

Starting with Postgres 10, identity columns as defined by the SQL standard are also supported:

create table foo 
(
  id integer generated always as identity
);

creates an identity column that can't be overridden unless explicitly asked for. The following insert will fail with a column defined as generated always:

insert into foo (id) 
values (1);

This can however be overruled:

insert into foo (id) overriding system value 
values (1);

When using the option generated by default this is essentially the same behaviour as the existing serial implementation:

create table foo 
(
  id integer generated by default as identity
);

When a value is supplied manually, the underlying sequence needs to be adjusted manually as well - the same as with a serial column.

An identity column is not a primary key by default (just like a serial column). If it should be one, a primary key constraint needs to be defined manually.

Download the file and from the same directory run docker build -t nodebb .

This will give you an image on your local machine that's named nodebb that you can launch an container from with docker run -d nodebb (you can change nodebb to your own name).

Since you are creating a markup as a string you don't have convert it into json. Just send it as it is combining all the array elements using implode method. Try this.

PHP change

$response = array();
$response[] = "<a href=''>link</a>";
$response[] = 1;
echo implode("", $response);//<-----Combine array items into single string

JS (Change the dataType from json to html or just don't set it jQuery will figure it out)

$.ajax({
   type: "POST", 
   dataType: "html", 
   url: "main.php", 
   data: "action=loadall&id=" + id,
   success: function(response){
      $('#main').html(response);
   }
});
