Programs & Examples On #Dockpanel

The reason that this is happening is because the stack panel measures every child element with positive infinity as the constraint for the axis that it is stacking elements along. The child controls have to return how big they want to be (positive infinity is not a valid return from the MeasureOverride in either axis) so they return the smallest size where everything will fit. They have no way of knowing how much space they really have to fill.

If your view doesn’t need to have a scrolling feature and the answer above doesn't suit your needs, I would suggest implement your own panel. You can probably derive straight from StackPanel and then all you will need to do is change the ArrangeOverride method so that it divides the remaining space up between its child elements (giving them each the same amount of extra space). Elements should render fine if they are given more space than they wanted, but if you give them less you will start to see glitches.

If you want to be able to scroll the whole thing then I am afraid things will be quite a bit more difficult, because the ScrollViewer gives you an infinite amount of space to work with which will put you in the same position as the child elements were originally. In this situation you might want to create a new property on your new panel which lets you specify the viewport size, you should be able to bind this to the ScrollViewer’s size. Ideally you would implement IScrollInfo, but that starts to get complicated if you are going to implement all of it properly.

Some of the above solutions did not work for me. The .fig attribute was not found when I tried that and I was unable to use .savefig() directly. However, what did work was:

sns_plot.figure.savefig("output.png")

I am a newer Python user, so I do not know if this is due to an update. I wanted to mention it in case anybody else runs into the same issues as I did.

If you have two lists that have the predicted and actual values; as it appears you do, you can pass them to a function that will calculate TP, FP, TN, FN with something like this:

def perf_measure(y_actual, y_hat):
    TP = 0
    FP = 0
    TN = 0
    FN = 0

    for i in range(len(y_hat)): 
        if y_actual[i]==y_hat[i]==1:
           TP += 1
        if y_hat[i]==1 and y_actual[i]!=y_hat[i]:
           FP += 1
        if y_actual[i]==y_hat[i]==0:
           TN += 1
        if y_hat[i]==0 and y_actual[i]!=y_hat[i]:
           FN += 1

    return(TP, FP, TN, FN)

From here I think you will be able to calculate rates of interest to you, and other performance measure like specificity and sensitivity.

mysql_* functions have been removed in PHP 7.

You probably have PHP 7 in XAMPP. You now have two alternatives: MySQLi and PDO.

Additionally, here is a nice wiki page about PDO.

Since you've already received help on the query, I'll take a poke at your syntax question:

The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join and on clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.

Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:

select
 count(*)
from Table1 as t1
join Table2 as t2
    join Table3 as t3
    on t2.Key = t3.Key                   -- join #1
    and t2.Key2 = t3.Key2 
on t1.DifferentKey = t3.DifferentKey     -- join #2  

This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:

select
 count(*)
from Table1 as t1
    join Table3 as t3
        join Table2 as t2
        on t2.Key = t3.Key                   -- join #1
        and t2.Key2 = t3.Key2   
    on t1.DifferentKey = t3.DifferentKey     -- join #2

Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.

There is no standard way to do this. You need to use 3rd party tools such as ApexSQL Restore or SQL Virtual Restore. These tools don’t really read the backup file directly. They get SQL Server to “think” of backup files as if these were live databases.

Perhaps, a good way is just to cut out a substring:

String St = "super exemple of string key : text I want to keep - end of my string";

int pFrom = St.IndexOf("key : ") + "key : ".Length;
int pTo = St.LastIndexOf(" - ");

String result = St.Substring(pFrom, pTo - pFrom);

In python 3s print function:

lst = [1, 2, 3]
print('My list:', *lst, sep='\n- ')

Output:

My list:
- 1
- 2
- 3

Con: The sep must be a string, so you can't modify it based on which element you're printing. And you need a kind of header to do this (above it was 'My list:').

Pro: You don't have to join() a list into a string object, which might be advantageous for larger lists. And the whole thing is quite concise and readable.

I also had this problem. To sort out the problem of spaces in the middle of the string this line of code always works:

String field = field.replaceAll("\\s+", "");

You can use this code into viewDidLoad or viewDidAppear where your table being created:

// Remove blank space on header of table view
 videoListUITableView.contentInset = UIEdgeInsetsZero;

// The iOS device = iPhone or iPod Touch
CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;

// Set the height of the table on the basis of number of rows
videoListUITableView.frame = CGRectMake(videoListUITableView.frame.origin.x, videoListUITableView.frame.origin.y, videoListUITableView.frame.size.width, iOSDeviceScreenSize.height-100);



// Hide those cell which doesn't contain any kind of data
self.videoListUITableView.tableFooterView = [[UIView alloc] init];

To remove the "keep-alive" header in requests, I just created it from the Request object and then send it with Session

headers = {
'Host' : '1.2.3.4',
'User-Agent' : 'Test client (x86_64-pc-linux-gnu 7.16.3)',
'Accept' : '*/*',
'Accept-Encoding' : 'deflate, gzip',
'Accept-Language' : 'it_IT'
}

url = "https://stream.twitter.com/1/statuses/filter.json"
#r = requests.get(url, headers = headers) #this triggers keep-alive: True
s = requests.Session()
r = requests.Request('GET', url, headers)

Time::HiRes:

Judge by yesterday's weather. How long did it take last time? Are you trending longer or shorter? Each shop is different.

Most agile shops need a lot less time, have drastically fewer defects, and quicker time to resolve them because of TDD. Even so, most agile shops have some measurable time spent with testing/QC.

If this is the first test run for this application, then the answer is "lets see" followed by an attempt. It depends on how quick you can get questions answered, - how testable it is, - how many features/functions - how many defects are discovered, - how quickly issues are resolved, - how many times the code cycles through testing, and - how many times testing is blocked by bugs. There is no way to tell. You could call it 50% or 175% or more, and not be wrong. Why not make a rough guess and multiply by Pi? It won't be much worse than any other answer you can make up.

You should (must) know how long it takes now and whether it's getting faster or slower, and whether the coverage is increasing or decreasing. With those three bits of information, you should be able to guess quite well.

(See update at end of answer.)

You can get a NodeList of all of the input elements via getElementsByTagName (DOM specification, MDC, MSDN), then simply loop through it:

var inputs, index;

inputs = document.getElementsByTagName('input');
for (index = 0; index < inputs.length; ++index) {
    // deal with inputs[index] element.
}

There I've used it on the document, which will search the entire document. It also exists on individual elements (DOM specification), allowing you to search only their descendants rather than the whole document, e.g.:

var container, inputs, index;

// Get the container element
container = document.getElementById('container');

// Find its child `input` elements
inputs = container.getElementsByTagName('input');
for (index = 0; index < inputs.length; ++index) {
    // deal with inputs[index] element.
}

...but you've said you don't want to use the parent form, so the first example is more applicable to your question (the second is just there for completeness, in case someone else finding this answer needs to know).

Update: getElementsByTagName is an absolutely fine way to do the above, but what if you want to do something slightly more complicated, like just finding all of the checkboxes instead of all of the input elements?

That's where the useful querySelectorAll comes in: It lets us get a list of elements that match any CSS selector we want. So for our checkboxes example:

var checkboxes = document.querySelectorAll("input[type=checkbox]");

You can also use it at the element level. For instance, if we have a div element in our element variable, we can find all of the spans with the class foo that are inside that div like this:

var fooSpans = element.querySelectorAll("span.foo");

querySelectorAll and its cousin querySelector (which just finds the first matching element instead of giving you a list) are supported by all modern browsers, and also IE8.

Excuse me when I answer your questions out-of-order, it makes it easier to understand this way.

When static variable is declared in a header file is its scope limited to .h file or across all units.

There is no such thing as a "header file scope". The header file gets included into source files. The translation unit is the source file including the text from the header files. Whatever you write in a header file gets copied into each including source file.

As such, a static variable declared in a header file is like a static variable in each individual source file.

Since declaring a variable static this way means internal linkage, every translation unit #includeing your header file gets its own, individual variable (which is not visible outside your translation unit). This is usually not what you want.

I would like to know what is the difference between static variables in a header file vs declared in a class.

In a class declaration, static means that all instances of the class share this member variable; i.e., you might have hundreds of objects of this type, but whenever one of these objects refers to the static (or "class") variable, it's the same value for all objects. You could think of it as a "class global".

Also generally static variable is initialized in .cpp file when declared in a class right ?

Yes, one (and only one) translation unit must initialize the class variable.

So that does mean static variable scope is limited to 2 compilation units ?

As I said:

• A header is not a compilation unit,
• static means completely different things depending on context.

Global static limits scope to the translation unit. Class static means global to all instances.

I hope this helps.

PS: Check the last paragraph of Chubsdad's answer, about how you shouldn't use static in C++ for indicating internal linkage, but anonymous namespaces. (Because he's right. ;-) )

window.location.href = window.location.href

This decision works fine:

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

But new activity launch long and you see white screen some time. If this is critical then use this workaround:

public class BaseActivity extends AppCompatActivity {

    private static final String ACTION_FINISH = "action_finish";

    private BroadcastReceiver finisBroadcastReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        registerReceiver(finisBroadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                finish();
            }
        }, new IntentFilter(ACTION_FINISH));
    }

    public void clearBackStack() {
        sendBroadcast(new Intent(ACTION_FINISH));
    }

    @Override
    protected void onDestroy() {
        unregisterReceiver(finisBroadcastReceiver);
        super.onDestroy();
    }
}

How use it:

public class ActivityA extends BaseActivity {

    // Click any button
    public void startActivityB() {
        startActivity(new Intent(this, ActivityB.class));
        clearBackStack();
    }
}

Disadvantage: all activities that must be closed on the stack must extends BaseActivity

# Powershell / Package manager console
Script-Migration

# Cli 
dotnet ef migrations script

You can use the -From and -To parameter to generate an update script to update a database to a specific version.

Script-Migration -From 20190101011200_Initial-Migration -To 20190101021200_Migration-2

https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/#generate-sql-scripts

There are several options to this command.

The from migration should be the last migration applied to the database before running the script. If no migrations have been applied, specify 0 (this is the default).

The to migration is the last migration that will be applied to the database after running the script. This defaults to the last migration in your project.

An idempotent script can optionally be generated. This script only applies migrations if they haven't already been applied to the database. This is useful if you don't exactly know what the last migration applied to the database was or if you are deploying to multiple databases that may each be at a different migration.

Use List.AddRange(collection As IEnumerable(Of T)) method.

It allows you to append at the end of your list another collection/list.

Example:

List<string> initialList = new List<string>();
// Put whatever you want in the initial list
List<string> listToAdd = new List<string>();
// Put whatever you want in the second list
initialList.AddRange(listToAdd);

Based on Bootstrap doc:

As of v3.1.0, .pull-right is deprecated on dropdown menus. use .dropdown-menu-right

is there a possibility that casting a double created via Math.round() will still result in a truncated down number

No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. But after rounding, there will not be any fractional parts remaining.

Here are the docs from Math.round(double):

Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type long. In other words, the result is equal to the value of the expression:

(long)Math.floor(a + 0.5d)

Make a method of MsgBox in your page.

public void MsgBox(String ex, Page pg,Object obj) 
{
    string s = "<SCRIPT language='javascript'>alert('" + ex.Replace("\r\n", "\\n").Replace("'", "") + "'); </SCRIPT>";
    Type cstype = obj.GetType();
    ClientScriptManager cs = pg.ClientScript;
    cs.RegisterClientScriptBlock(cstype, s, s.ToString());
}

and when you want to use msgbox just put this line

MsgBox("! your message !", this.Page, this);

Q) Code was working fine in Intellj but failing in command line.

Sol) Add dependencies of jersey as a direct dependency rather than a transient one.

Reasoning: Since, it was working fine with IntelliJ, dependencies are correctly configured.

1. Get required dependencies by one of the following:

   1. check for the IntelliJ running command. Stackoverflow-link
   2. List dependencies from maven mvn dependency:tree

2. Now, add those problematic jersey dependencies explicitly.

In the example you gave, the method will never throw an IOException, therefore the declaration is wrong (but valid). My guess is that the original method threw the IOException, but it was then updated to handle the exception within but the declaration was not changed.

I know this is an older question, but I found this nifty library on nuget that seems to do just the trick for me:

    println new Integer(a) * new Integer(b)
}

BUILD SUCCESSFUL

first, you need to find the toolbox that you need. There are many people developing 3rd party toolboxes for Matlab, so there isn't just one single place where you can find "the image processing toolbox". That said, a good place to start looking is the Matlab Central which is a Mathworks-run site for exchanging all kinds of Matlab-related material.

Once you find a toolbox you want, it will be in some compressed format, and its developers might have a "readme" file that details on how to install it. If it isn't the case, a generic way to attempt installation is to place the toolbox in any directory on your drive, and then add it to Matlab path, e.g., going to File -> Set Path... -> Add Folder or Add with Subfolders (I'm writing for memory but this is definitely close).

Otherwise, you can extract all .m files in your working directory, if you don't want to use downloaded toolbox in more than one project.

overriding is reserved for instance members to support polymorphic behaviour. static class members do not belong to a particular instance. instead, static members belong to the class and as a result overriding is not supported because subclasses only inherit protected and public instance members and not static members. You may want to define an inerface and research factory and/or strategy design patterns to evaluate an alternate approach.

I agree with zach that counting within dplyr is the best solution. I've found this to be the shortest version:

dplyr::count(theTable, Position) %>%
          arrange(-n) %>%
          mutate(Position = factor(Position, Position)) %>%
          ggplot(aes(x=Position, y=n)) + geom_bar(stat="identity")

This will also be significantly faster than reordering the factor levels beforehand since the count is done in dplyr not in ggplot or using table.

Since MVC 5 you can use the built in Attribute Routing package which supports a datetime type, which will accept anything that can be parsed to a DateTime.

e.g.

[GET("Orders/{orderDate:datetime}")]

More info here.

Having 2 files like you suggested would be the easiest solution.

For instance:

2 files solution:

index.html

(.. your html ..)
<form action="script.php" method="get">
  <input type="submit" value="Run me now!">
</form>
(...)

script.php

<?php
  echo "Hello world!"; // Your code here
?>

Single file solution:

index.php

<?php
  if (!empty($_GET['act'])) {
    echo "Hello world!"; //Your code here
  } else {
?>
(.. your html ..)
<form action="index.php" method="get">
  <input type="hidden" name="act" value="run">
  <input type="submit" value="Run me now!">
</form>
<?php
  }
?>

The answer by @chepner will copy all the sub-directories irrespective of the fact if it contains the file or not. If you need to exclude the sub-directories that dont contain the file and still retain the directory structure, use

rsync -zarv  --prune-empty-dirs --include "*/"  --include="*.sh" --exclude="*" "$from" "$to"

For arbitrary levels of nestedness:

In [2]: def nested_dict():
   ...:     return collections.defaultdict(nested_dict)
   ...:

In [3]: a = nested_dict()

In [4]: a
Out[4]: defaultdict(<function __main__.nested_dict>, {})

In [5]: a['a']['b']['c'] = 1

In [6]: a
Out[6]:
defaultdict(<function __main__.nested_dict>,
            {'a': defaultdict(<function __main__.nested_dict>,
                         {'b': defaultdict(<function __main__.nested_dict>,
                                      {'c': 1})})})

Reflection can take you from an object to a dictionary by iterating over the properties.

To go the other way, you'll have to use a dynamic ExpandoObject (which, in fact, already inherits from IDictionary, and so has done this for you) in C#, unless you can infer the type from the collection of entries in the dictionary somehow.

So, if you're in .NET 4.0 land, use an ExpandoObject, otherwise you've got a lot of work to do...

items() returns a list, and it is that list you are iterating, so mutating the dict in the loop doesn't matter here. If you were using iteritems() instead, mutating the dict in the loop would be problematic, and likewise for viewitems() in Python 2.7.

I can't think of a better way to remove items from a dict by value.

You need to initialize your mongoDB database first, you can run "mongod" in your terminal and then it will be working fine.

If you right-click on your project, there should be an option under "maven" to "enable dependency management". That's it.

First of all we should not read parameters within the filter. Usually the headers are read in the filter to do few authentication tasks. Having said that one can read the HttpRequest body completely in the Filter or Interceptor by using the CharStreams:

String body = com.google.common.io.CharStreams.toString(request.getReader());

This does not affect the subsequent reads at all.

I solved the same issue with this css:

    pointer-events:none;

for plesk hosts, one of these should do: (both do the same)

mysqlrepair -uadmin -p$(cat /etc/psa/.psa.shadow) -A
# or
mysqlcheck -uadmin -p$(cat /etc/psa/.psa.shadow) --repair -A

I had follow all above steps but it's not work form me finally. I was created duplicate Target and it's working fine. I have no idea what's wrong maybe cache memory issue

If you are doing a loading screen, just set the parameter to not keep it in activity stack. In your manifest.xml, where you define your activity do:

<activity android:name=".LoadingScreen" android:noHistory="true" ... />

And in your code there is no need to call .finish() anymore. Just do startActivity(i);

There is also no need to keep a instance of your current activity in a separate field. You can always access it like LoadingScreen.this.doSomething() instead of private LoadingScreen loadingScreen;

Here is a solution for doing it with a single div element with CSS properties, border-radius does the magic.

CSS:

.circle{
    width:100px;
    height:100px;
    border-radius:50px;
    font-size:20px;
    color:#fff;
    line-height:100px;
    text-align:center;
    background:#000
}

HTML:

<div class="circle">Hello</div>

It's very simple for Python 3.x (docs).

import csv

with open('output_file_name', 'w', newline='', encoding='utf-8') as csv_file:
    writer = csv.writer(csv_file, delimiter=';')
    writer.writerow('my_utf8_string')

For Python 2.x, look here.

The best way is to user sass-loader. It is available as npm package. It resolves all path related issues and make it super easy.

Are there other ways?

Negative margins were also used for horizontal (and vertical!) centering but there are quite a few drawbacks when you resize the window browser: no window slider; the content can't be seen anymore if the size of the window browser is too small.
No surprise as it uses absolute positioning, a beast never completely tamed!

Example: http://bluerobot.com/web/css/center2.html

So that was only FYI as you asked for it, margin: 0 auto; is a better solution.

Based on @Arun P Johny this is how you do it for an input:

<input type="button" class="btEdit" id="myButton1">

This is how I got it in jQuery:

$(document).on('click', "input.btEdit", function () {
    var id = this.id;
    console.log(id);
});

This will log on the console: myButton1. As @Arun said you need to add the event dinamically, but in my case you don't need to call the parent first.

UPDATE

Though it would be better to say:

$(document).on('click', "input.btEdit", function () {
    var id = $(this).id;
    console.log(id);
});

Since this is JQuery's syntax, even though both will work.

As with most things you should pick which to use based on the context and what is conceptually the correct way to go. A switch is really saying "pick one of these based on this variables value" but an if statement is just a series of boolean checks.

As an example, if you were doing:

int value = // some value
if (value == 1) {
    doThis();
} else if (value == 2) {
    doThat();
} else {
    doTheOther();
}

This would be much better represented as a switch as it then makes it immediately obviously that the choice of action is occurring based on the value of "value" and not some arbitrary test.

Also, if you find yourself writing switches and if-elses and using an OO language you should be considering getting rid of them and using polymorphism to achieve the same result if possible.

Finally, regarding switch taking longer to type, I can't remember who said it but I did once read someone ask "is your typing speed really the thing that affects how quickly you code?" (paraphrased)

make sure the service is stopped, the services control panel is closed, and no open file handles are open by the service.

Also make sure ProcessExplorer is not running.

Here is a simple explanation about how to create a temp dir using templates.

1. Creates a temporary file or directory, safely, and prints its name.
2. TEMPLATE must contain at least 3 consecutive 'X's in last component.
3. If TEMPLATE is not specified, it will use tmp.XXXXXXXXXX
4. directories created are u+rwx, minus umask restrictions.

PARENT_DIR=./temp_dirs # (optional) specify a dir for your tempdirs
mkdir $PARENT_DIR

TEMPLATE_PREFIX='tmp' # prefix of your new tempdir template
TEMPLATE_RANDOM='XXXX' # Increase the Xs for more random characters
TEMPLATE=${PARENT_DIR}/${TEMPLATE_PREFIX}.${TEMPLATE_RANDOM}

# create the tempdir using your custom $TEMPLATE, which may include
# a path such as a parent dir, and assign the new path to a var
NEW_TEMP_DIR_PATH=$(mktemp -d $TEMPLATE)
echo $NEW_TEMP_DIR_PATH

# create the tempdir in parent dir, using default template
# 'tmp.XXXXXXXXXX' and assign the new path to a var
NEW_TEMP_DIR_PATH=$(mktemp -p $PARENT_DIR)
echo $NEW_TEMP_DIR_PATH

# create a tempdir in your systems default tmp path e.g. /tmp 
# using the default template 'tmp.XXXXXXXXXX' and assign path to var
NEW_TEMP_DIR_PATH=$(mktemp -d)
echo $NEW_TEMP_DIR_PATH

# Do whatever you want with your generated temp dir and var holding its path

Valid hex colors can contain 0 to 9 and A to F so if we create a string with those characters and then shuffle it, we can grab the first 6 characters to create a random hex color code. An example is below!

code

echo '#' . substr(str_shuffle('ABCDEF0123456789'), 0, 6);

I tested this in a while loop and generated 10,000 unique colors.

code I used to generate 10,000 unique colors:

$colors = array();
while (true) {
   $color          = substr(str_shuffle('ABCDEF0123456789'), 0, 6);
   $colors[$color] = '#' . $color;
   if ( count($colors) == 10000 ) {
      echo implode(PHP_EOL, $colors);
      break;
   }
}

Which gave me these random colors as the result.

outis pointed out that my first example couldn't generate hexadecimals such as '4488CC' so I created a function which would be able to generate hexadecimals like that.

code

function randomHex() {
   $chars = 'ABCDEF0123456789';
   $color = '#';
   for ( $i = 0; $i < 6; $i++ ) {
      $color .= $chars[rand(0, strlen($chars) - 1)];
   }
   return $color;
}

echo randomHex();

The second example would be better to use because it can return a lot more different results than the first example, but if you aren't going to generate a lot of color codes then the first example would work just fine.

I have a slightly longer formatter for JavaScript here...

You can do formatting several ways:

• String.format(input, args0, arg1, ...)
• String.format(input, obj)
• "literal".format(arg0, arg1, ...)
• "literal".format(obj)

Also, if you have say a ObjectBase.prototype.format (such as with DateJS) it will use that.

Examples...

var input = "numbered args ({0}-{1}-{2}-{3})";
console.log(String.format(input, "first", 2, new Date()));
//Outputs "numbered args (first-2-Thu May 31 2012...Time)-{3})"

console.log(input.format("first", 2, new Date()));
//Outputs "numbered args(first-2-Thu May 31 2012...Time)-{3})"

console.log(input.format(
    "object properties ({first}-{second}-{third:yyyy-MM-dd}-{fourth})"
    ,{
        'first':'first'
        ,'second':2
        ,'third':new Date() //assumes Date.prototype.format method
    }
));
//Outputs "object properties (first-2-2012-05-31-{3})"

I've also aliased with .asFormat and have some detection in place in case there's already a string.format (such as with MS Ajax Toolkit (I hate that library).

I wrap the whole logic of daily line processing as a npm module: line-kit https://www.npmjs.com/package/line-kit

// example_x000D_
var count = 0_x000D_
require('line-kit')(require('fs').createReadStream('/etc/issue'),_x000D_
                    (line) => { count++; },_x000D_
                    () => {console.log(`seen ${count} lines`)})

The e.offsetWidth < e.scrollWidth solution is not always working.

And if you want to use pure JavaScript, I recommend to use this:

(typescript)

public isEllipsisActive(element: HTMLElement): boolean {
    element.style.overflow = 'initial';
    const noEllipsisWidth = element.offsetWidth;
    element.style.overflow = 'hidden';
    const ellipsisWidth = element.offsetWidth;

    if (ellipsisWidth < noEllipsisWidth) {
      return true;
    } else {
      return false;
    }
}

The clean way to do so is to pass a new instance of the created entity through the controller:

//GET
public ActionResult CreateNewMyEntity(string default_value)
{
    MyEntity newMyEntity = new MyEntity();
    newMyEntity._propertyValue = default_value;

    return View(newMyEntity);
}

If you want to pass the default value through ActionLink

@Html.ActionLink("Create New", "CreateNewMyEntity", new { default_value = "5" })

I have used Sphinx, Solr and Elasticsearch. Solr/Elasticsearch are built on top of Lucene. It adds many common functionality: web server api, faceting, caching, etc.

If you want to just have a simple full text search setup, Sphinx is a better choice.

If you want to customize your search at all, Elasticsearch and Solr are the better choices. They are very extensible: you can write your own plugins to adjust result scoring.

Some example usages:

• Sphinx: craigslist.org
• Solr: Cnet, Netflix, digg.com
• Elasticsearch: Foursquare, Github

$memberId =$_SESSION['TWILLO']['Id'];

    $QueryServer=mysql_query("select * from smtp_server where memberId='".$memberId."'");
    $data = array();
    while($ser=mysql_fetch_assoc($QueryServer))
    {

     $data[$ser['Id']] =array('ServerName','ServerPort','Server_limit','email','password','status');

    }

It is XOR. Another name for the XOR function is addition without carry. I suppose that's how the symbol might make sense.

If there is no ORDER BY clause, then TOP 100 PERCENT is redundant. (As you mention, this was the 'trick' with views)

[Hopefully the optimizer will optimize this away.]

This message will appear if you are using a case-insensitive file system (e.g. on a Mac) and you're trying to capitalize the name (or another change of case). In which case you need to rename to a third, dummy, name:

svn mv file-name file-name_
svn mv file-name_ FILE_Name
svn commit

I suggest to add the '+' operator as follows:

list = list + ['foo']

Hope it helps!

There's now a UITextField delegate method available on iOS13+

Access the json array like you would any other array.

for(var i =0;i < itemData.length-1;i++)
{
  var item = itemData[i];
  alert(item.Test1 + item.Test2 + item.Test3);
}

Pandas v0.13+: Use to_csv with date_format parameter

Avoid, where possible, converting your datetime64[ns] series to an object dtype series of datetime.date objects. The latter, often constructed using pd.Series.dt.date, is stored as an array of pointers and is inefficient relative to a pure NumPy-based series.

Since your concern is format when writing to CSV, just use the date_format parameter of to_csv. For example:

df.to_csv(filename, date_format='%Y-%m-%d')

See Python's strftime directives for formatting conventions.

I got this because I had more than 1 user account on my box. I was logged in as user A and was in a directory for user B. User A didn't have permission to user B's stuff. Once I realized I wasn't where I thought I was in the file system, this error made sense.

As paxdiablo said make -f pax.mk would execute the pax.mk makefile, if you directly execute it by typing ./pax.mk, then you would get syntax error.

Also you can just type make if your file name is makefile/Makefile.

Suppose you have two files named makefile and Makefile in the same directory then makefile is executed if make alone is given. You can even pass arguments to makefile.

Check out more about makefile at this Tutorial : Basic understanding of Makefile

jQuery("input:radio[name=myradiobutton]:checked").val();

Windows Runtime equivalent of a function object in standard C++. One can use the whole function as a parameter (actually that is a function pointer). It is mostly used in conjunction with events. The delegate represents a contract that event handlers much fulfill. It facilitate how a function pointer can work for.

The following code works for me.

//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);

method implementation:

public static String sendPostRequest(String requestUrl, String payload) {
    try {
        URL url = new URL(requestUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Accept", "application/json");
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
        writer.write(payload);
        writer.close();
        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        StringBuffer jsonString = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
                jsonString.append(line);
        }
        br.close();
        connection.disconnect();
        return jsonString.toString();
    } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
    }

}

Static fields are initialized when the class is loaded by the class loader. Default values are assigned at this time. This is done in the order than they appear in the source code.

Suppose your dataframe is df and you want to change gender from 2 to 1 in participant id 5 then you should determine the row by writing "==" as you can see

 df["rowName", "columnName"] <- value
 df[df$serial.id==5, "gender"] <- 1

In vanilla/pure javascript you can check as following -

var field = document.querySelector("input[name='fieldName']");
if(field.readOnly){
 alert("foo");
}

The two common to print a blank line in Python-

1. The old school way:

   print "hello\n"

2. Writing the word print alone would do that:

   print "hello"

   print

You can do it calling setRowSelectionInterval :

table.setRowSelectionInterval(0, 0);

to select the first row.

The easiest way would be to use a GUI:

For Gnome use gnome-schedule (universe)

sudo apt-get install gnome-schedule 

For KDE use kde-config-cron

It should be pre installed on Kubuntu

But if you use a headless linux or don´t want GUI´s you may use:

crontab -e

If you type it into Terminal you´ll get a table.
You have to insert your cronjobs now.
Format a job like this:

*     *     *     *     *  YOURCOMMAND
-     -     -     -     -
|     |     |     |     |
|     |     |     |     +----- Day in Week (0 to 7) (Sunday is 0 and 7)
|     |     |     +------- Month (1 to 12)
|     |     +--------- Day in Month (1 to 31)
|     +----------- Hour (0 to 23)
+------------- Minute (0 to 59)

There are some shorts, too (if you don´t want the *):

@reboot --> only once at startup
@daily ---> once a day
@midnight --> once a day at midnight
@hourly --> once a hour
@weekly --> once a week
@monthly --> once a month
@annually --> once a year
@yearly --> once a year

If you want to use the shorts as cron (because they don´t work or so):

@daily --> 0 0 * * *
@midnight --> 0 0 * * *
@hourly --> 0 * * * *
@weekly --> 0 0 * * 0
@monthly --> 0 0 1 * *
@annually --> 0 0 1 1 *
@yearly --> 0 0 1 1 *

One can access the "Find in Files" window via the drop-down menu selection and search all files in the Entire Solution: Edit > Find and Replace > Find in Files

If the browser that you are planning to use is Mozilla (Addon development) (not sure of chrome) you can use the following method in Javascript

function DOM( string )
{
    var {Cc, Ci} = require("chrome");
    var parser = Cc["@mozilla.org/xmlextras/domparser;1"].createInstance(Ci.nsIDOMParser);
    console.log("PARSING OF DOM COMPLETED ...");
    return (parser.parseFromString(string, "text/html"));
};

Hope this helps

Empty lists evaluate to False in boolean contexts (such as if some_list:).

Take a look at the FormBorderStyle property

form1.FormBorderStyle = FormBorderStyle.FixedSingle;

You may also want to remove the minimize and maximize buttons:

form1.MaximizeBox = false;
form1.MinimizeBox = false;

SELECT *
FROM   sys.all_sql_modules
WHERE  definition LIKE '%CreatedDate%'

you must parse JSON string to become object

var dataObject = jQuery.parseJSON(data);

so you can call it like:

success: function (data) {
    var dataObject = jQuery.parseJSON(data);
    if (dataObject.success == 1) {
       var insertedGoalId = dataObject.inserted.goal_id;
       ...
       ...
    }
}

Correct attribute value for Asp.Net MVC Core to prevent browser caching (including Internet Explorer 11) is:

explain select * from test where id in (values (1), (2));

QUERY PLAN

 Seq Scan on test  (cost=0.00..1.38 rows=2 width=208)
   Filter: (id = ANY ('{1,2}'::bigint[]))

But if try 2nd query:

explain select * from test where id = any (values (1), (2));

QUERY PLAN

Hash Semi Join  (cost=0.05..1.45 rows=2 width=208)
       Hash Cond: (test.id = "*VALUES*".column1)
       ->  Seq Scan on test  (cost=0.00..1.30 rows=30 width=208)
       ->  Hash  (cost=0.03..0.03 rows=2 width=4)
             ->  Values Scan on "*VALUES*"  (cost=0.00..0.03 rows=2 width=4)

We can see that postgres build temp table and join with it

An update on @Scott T.'s answer: the interface between Resource Server and Authorization Server for token validation was standardized in IETF RFC 7662 in October 2015, see: https://tools.ietf.org/html/rfc7662. A sample validation call would look like:

POST /introspect HTTP/1.1
Host: server.example.com
Accept: application/json
Content-Type: application/x-www-form-urlencoded
Authorization: Bearer 23410913-abewfq.123483

token=2YotnFZFEjr1zCsicMWpAA

and a sample response:

HTTP/1.1 200 OK
Content-Type: application/json

{
  "active": true,
  "client_id": "l238j323ds-23ij4",
  "username": "jdoe",
  "scope": "read write dolphin",
  "sub": "Z5O3upPC88QrAjx00dis",
  "aud": "https://protected.example.net/resource",
  "iss": "https://server.example.com/",
  "exp": 1419356238,
  "iat": 1419350238,
  "extension_field": "twenty-seven"
}

Of course adoption by vendors and products will have to happen over time.

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

If RoleAssignments is a List<T> you can use the following code.

workSpace.RoleAssignments.RemoveAll(x =>x.Member.Name == shortName);

Not the best way ,but will still work

If you work in MS Visual Studio just do following

1. Put WSDL file and XSD file at the same folder.

2. Correct WSDL file like this YourSchemeFile.xsd

3. Use visual Studio using this great example How to generate service reference with only physical wsdl file

Notice that you have to put the path to your WSDL file manually. There is no way to use Open File dialog box out there.

I believe you need quotes around the model:

JSON.stringify({ "model": source })

First you don't need a transaction since you are just querying select statements and since they are both select statement you can just combine them into one query separated by space and use Dataset to get the all the tables retrieved. Its better this way since you made only one transaction to the database because database transactions are expensive hence your code is faster. Second of you really have to use a transaction, just assign the transaction to the SqlCommand like

sqlCommand.Transaction = transaction;

And also just use one SqlCommand don't declare more than one, since variables consume space and we are also on the topic of making your code more efficient, do that by assigning commandText to different query string and executing them like

sqlCommand.CommandText = "select * from table1";
sqlCommand.ExecuteNonQuery();
sqlCommand.CommandText = "select * from table2";
sqlCommand.ExecuteNonQuery();

You can also use this very simplified form:

@Html.ActionLink("Come back to Home", "Index", "Home")

Where :
Come back to Home is the text that will appear on the page
Index is the view name
Homeis the controller name

The problem with source is that it requires the file to have a proper bash syntax, and some special characters will ruin it: =, ", ', <, >, and others. So in some cases you can't just

source development.env

This version, however, withstands every special character in values:

set -a
source <(cat development.env | \
    sed -e '/^#/d;/^\s*$/d' -e "s/'/'\\\''/g" -e "s/=\(.*\)/='\1'/g")
set +a

Explanation:

• -a means that every bash variable would become an environment variable
• /^#/d removes comments (strings that start with #)
• /^\s*$/d removes empty strings, including whitespace
• "s/'/'\\\''/g" replaces every single quote with '\'', which is a trick sequence in bash to produce a quote :)
• "s/=\(.*\)/='\1'/g" converts every a=b into a='b'

As a result, you are able to use special characters :)

To debug this code, replace source with cat and you'll see what this command produces.

This happened to me. It's because I ran make -j 4 and some jobs finished out of order. This warning should be expected when using the -j option.

You need to install this extension to Visual Studio 2017/2019 in order to get access to the Installer Projects.

According to the page:

This extension provides the same functionality that currently exists in Visual Studio 2015 for Visual Studio Installer projects. To use this extension, you can either open the Extensions and Updates dialog, select the online node, and search for "Visual Studio Installer Projects Extension," or you can download directly from this page.

Once you have finished installing the extension and restarted Visual Studio, you will be able to open existing Visual Studio Installer projects, or create new ones.

    from p in PriceLog
    group p by p.LogDateTime.ToString("MMM") into g
    select new 
    { 
        LogDate = g.Key.ToString("MMM yyyy"),
        GoldPrice = (int)dateGroup.Average(p => p.GoldPrice), 
        SilverPrice = (int)dateGroup.Average(p => p.SilverPrice) 
    }

Whenever you create child class object then that object has all the features of parent class. Here Super() is the facilty for accession parent.

If you write super() at that time parents's default constructor is called. same if you write super.

this keyword refers the current object same as super key word facilty for accessing parents.

What if javascript is Turned Off on clients machine? Use following solution for all scenarios. You dont even need javascript/jQuery. :

HTML

<label for="fileInput"><img src="File_upload_Img"><label>
<input type="file" id="fileInput"></label>

CSS

#fileInput{opacity:0}  
body{
    background:cadetblue;
}

Explanation : for="Your input Id" . Triggers click event by default by HTML. So it by default triggers click event, no need of jQuery/javascript. If its simply done by HTML why use jQuery/jScript? And you cant tell if client disabled JS. Your feature should work even though JS is turned off.

You can also use org.apache.commons.lang.StringUtils API to form a comma separated result from string array in Java.

StringUtils.join(strArr,",");

just put

$a='Link1';
$b='Link2';

in your pass.php and you will get your answer and do a double quotation in your link.php:

echo '<a href="pass.php?link=' . $a . '">Link 1</a>';

To iterate ASCII characters on a POSIX-compliant shell, you can avoid external tools by using the Parameter Expansions:

#!/bin/sh

str="Hello World!"

while [ ${#str} -gt 0 ]; do
    next=${str#?}
    echo "${str%$next}"
    str=$next
done

or

str="Hello World!"

while [ -n "$str" ]; do
    next=${str#?}
    echo "${str%$next}"
    str=$next
done

The problem is that your ui property uses a forward declaration of class Ui::MainWindowClass, hence the "incomplete type" error.

Including the header file in which this class is declared will fix the problem.

EDIT

Based on your comment, the following code:

namespace Ui
{
    class MainWindowClass;
}

does NOT declare a class. It's a forward declaration, meaning that the class will exist at some point, at link time.
Basically, it just tells the compiler that the type will exist, and that it shouldn't warn about it.

But the class has to be defined somewhere.

Note this can only work if you have a pointer to such a type.
You can't have a statically allocated instance of an incomplete type.

So either you actually want an incomplete type, and then you should declare your ui member as a pointer:

namespace Ui
{
    // Forward declaration - Class will have to exist at link time
    class MainWindowClass;
}

class MainWindow : public QMainWindow
{
    private:

        // Member needs to be a pointer, as it's an incomplete type
        Ui::MainWindowClass * ui;
};

Or you want a statically allocated instance of Ui::MainWindowClass, and then it needs to be declared. You can do it in another header file (usually, there's one header file per class).
But simply changing the code to:

namespace Ui
{
    // Real class declaration - May/Should be in a specific header file
    class MainWindowClass
    {};
}


class MainWindow : public QMainWindow
{
    private:

        // Member can be statically allocated, as the type is complete
        Ui::MainWindowClass ui;
};

will also work.

Note the difference between the two declarations. First uses a forward declaration, while the second one actually declares the class (here with no properties nor methods).

Note that there's no general solution to this. An XSD can easily describe something that does not map to a relational database.

While you can try to "automate" this, your XSD's must be designed with a relational database in mind, or it won't work out well.

If the XSD's have features that don't map well you'll have to (1) design a mapping of some kind and then (2) write your own application to translate the XSD's into DDL.

Been there, done that. Work for hire -- no open source available.

jQuery's .bind() fires in the order it was bound:

When an event reaches an element, all handlers bound to that event type for the element are fired. If there are multiple handlers registered, they will always execute in the order in which they were bound. After all handlers have executed, the event continues along the normal event propagation path.

Source: http://api.jquery.com/bind/

Because jQuery's other functions (ex. .click()) are shortcuts for .bind('click', handler), I would guess that they are also triggered in the order they are bound.

No need to calculate the actual height of the contents; you can just scroll down a lot:

$(function () {
  $('.messageScrollArea').scrollTop(1E10);
});

You can use

function factorial(n) {
    return [...Array(n+1).keys()].slice(1).reduce( (a,b) => a * b, 1 );
}

There is no reason to do splits to get the path, hostname, etc from a string that is a link. You just need to use a link

//create a new element link with your link
var a = document.createElement("a");
a.href="http://www.sitename.com/article/2009/09/14/this-is-an-article/";

//hide it from view when it is added
a.style.display="none";

//add it
document.body.appendChild(a);

//read the links "features"
alert(a.protocol);
alert(a.hostname)
alert(a.pathname)
alert(a.port);
alert(a.hash);

//remove it
document.body.removeChild(a);

You can easily do it with jQuery appending the element and reading its attr.

Update: There is now new URL() which simplifies it

const myUrl = new URL("https://www.example.com:3000/article/2009/09/14/this-is-an-article/#m123")

const parts = ['protocol', 'hostname', 'pathname', 'port', 'hash'];

parts.forEach(key => console.log(key, myUrl[key]))

update

Component inheritance is supported since 2.3.0-rc.0

original

So far, the most convenient for me is to keep template & styles into separate *html & *.css files and specify those through templateUrl and styleUrls, so it's easy reusable.

@Component {
    selector: 'my-panel',
    templateUrl: 'app/components/panel.html', 
    styleUrls: ['app/components/panel.css']
}
export class MyPanelComponent extends BasePanelComponent

Put it into a ScrollViewer.

take a look at the following examples

http://threejs.org/examples/#misc_controls_orbit

http://threejs.org/examples/#misc_controls_trackball

there are other examples for different mouse controls, but both of these allow the camera to rotate around a point and zoom in and out with the mouse wheel, the main difference is OrbitControls enforces the camera up direction, and TrackballControls allows the camera to rotate upside-down.

All you have to do is include the controls in your html document

<script src="js/OrbitControls.js"></script>

and include this line in your source

controls = new THREE.OrbitControls( camera, renderer.domElement );

In this piece of code the height of left panel will gets adjusted to the height of right panel dynamically...

function resizeDiv() {
var rh=$('.pright').height()+'px'.toString();
$('.pleft').css('height',rh);
}

You can try this here http://jsfiddle.net/SriharshaCR/7q585k1x/9/embedded/result/

/* Warning: macro mod evaluates its arguments' side effects multiple times. */
#define mod(r,m) (((r) % (m)) + ((r)<0)?(m):0)

... or just get used to getting any representative for the equivalence class.

Creating a text file in unix can be done through a text editor (vim, emacs, gedit, etc). But what you want might be something like this

echo "insert text here" > myfile.txt

That will put the text 'insert text here' into a file myfile.txt. To verify that this worked use the command 'cat'.

cat myfile.txt

If you want to append to a file use this

echo "append this text" >> myfile.txt

You can include it in the same where statement with the && operator...

x=> x.Lists.Include(l => l.Title).Where(l=>l.Title != String.Empty 
    && l.InternalName != String.Empty)

You can use any of the comparison operators (think of it like doing an if statement) such as...

List<Int32> nums = new List<int>();

nums.Add(3);
nums.Add(10);
nums.Add(5);

var results = nums.Where(x => x == 3 || x == 10);

...would bring back 3 and 10.

Since I just went though a drag, I'll try to write the answer I'd have wished for two hours ago. This is for people who don't just want the copy&paste solution

First: Do you wonder why copying and pasting paths works for some people while it doesn't work for others?** The main reason, solutions differ are different python versions, 2.x or 3.x. There are actually distinct versions of virtualenv and virtualenvwrapper that work with either python 2 or 3. If you are on python 2 install like so:

sudo pip install virutalenv
sudo pip install virtualenvwrapper

If you are planning to use python 3 install the related python 3 versions

sudo pip3 install virtualenv
sudo pip3 install virtualenvwrapper

You've successfully installed the packages for your python version and are all set, right? Well, try it. Type workon into your terminal. Your terminal will not be able to find the command (workon is a command of virtualenvwrapper). Of course it won't. Workon is an executable that will only be available to you once you load/source the file virtualenvwrapper.sh. But the official installation guide has you covered on this one, right?. Just open your .bash_profile and insert the following, it says in the documentation:

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh

Especially the command source /usr/local/bin/virtualenvwrapper.sh seems helpful since the command seems to load/source the desired file virtualenvwrapper.sh that contains all the commands you want to work with like workon and mkvirtualenv. But yeah, no. When following the official installation guide, you are very likely to receive the error from the initial post: mkvirtualenv: command not found. Still no command is being found and you are still frustrated. So whats the problem here? The problem is that virtualenvwrapper.sh is not were you are looking for it right now. Short reminder ... you are looking here:

source /usr/local/bin/virtualenvwrapper.sh

But there is a pretty straight forward way to finding the desired file. Just type

which virtualenvwrapper

to your terminal. This will search your PATH for the file, since it is very likely to be in some folder that is included in the PATH of your system.

If your system is very exotic, the desired file will hide outside of a PATH folder. In that case you can find the path to virtalenvwrapper.sh with the shell command find / -name virtualenvwrapper.sh

Your result may look something like this: /Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh Congratulations. You have found your missing file!. Now all you have to do is changing one command in your .bash_profile. Just change:

source "/usr/local/bin/virtualenvwrapper.sh"

to:

"/Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh"

Congratulations. Virtualenvwrapper does now work on your system. But you can do one more thing to enhance your solution. If you've found the file virtualenvwrapper.sh with the command which virtualenvwrapper.sh you know that it is inside of a folder of the PATH. So if you just write the filename, your file system will assume the file is inside of a PATH folder. So you you don't have to write out the full path. Just type:

source "virtualenvwrapper.sh"

Thats it. You are no longer frustrated. You have solved your problem. Hopefully.

This problem is because of your https that means SSL certification. Try on Localhost.

            System.out.println("Modulus" + privKey.getModulus());

            //get the public key

            FileInputStream fis1 = new FileInputStream(file1);

Note: You should not use the com.android.support and com.google.android.material dependencies in your app at the same time.

Add Material Components for Android in your build.gradle(app) file

dependencies {
    // ...
    implementation 'com.google.android.material:material:1.0.0-beta01'
    // ...
  }

If your app currently depends on the original Design Support Library, you can make use of the Refactor to AndroidX… option provided by Android Studio. Doing so will update your app’s dependencies and code to use the newly packaged androidx and com.google.android.material libraries.

If you don’t want to switch over to the new androidx and com.google.android.material packages yet, you can use Material Components via the com.android.support:design:28.0.0-alpha3 dependency.

What I do in my Asp Net Core Api applications it is to create a class that extends from ObjectResult and provide many constructors to customize the content and the status code. Then all my Controller actions use one of the costructors as appropiate. You can take a look at my implementation at: https://github.com/melardev/AspNetCoreApiPaginatedCrud

and

https://github.com/melardev/ApiAspCoreEcommerce

here is how the class looks like(go to my repo for full code):

public class StatusCodeAndDtoWrapper : ObjectResult
{



    public StatusCodeAndDtoWrapper(AppResponse dto, int statusCode = 200) : base(dto)
    {
        StatusCode = statusCode;
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, string message) : base(dto)
    {
        StatusCode = statusCode;
        if (dto.FullMessages == null)
            dto.FullMessages = new List<string>(1);
        dto.FullMessages.Add(message);
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, ICollection<string> messages) : base(dto)
    {
        StatusCode = statusCode;
        dto.FullMessages = messages;
    }
}

Notice the base(dto) you replace dto by your object and you should be good to go.

If targetSdkVersion is higher than 24, then FileProvider is used to grant access.

Create an xml file(Path: res\xml) provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

Add a Provider in AndroidManifest.xml

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/provider_paths"/>
</provider>

and replace

return Uri.fromFile(getOutputMediaFile(type));

To

               return FileProvider.getUriForFile(this,  BuildConfig.APPLICATION_ID + ".provider", getOutputMediaFile(type));

This does what you want:

public static void main (String[] args) {
    String a = "\\joe\\jill\\";
    String b = a.replaceAll("\\\\$", "").replaceAll("^\\\\", "");
    System.out.println(b);
}

The $ is used to remove the sequence in the end of string. The ^ is used to remove in the beggining.

As an alternative, you can use the syntax:

String b = a.replaceAll("\\\\$|^\\\\", "");

The | means "or".

In case you want to trim other chars, just adapt the regex:

String b = a.replaceAll("y$|^x", ""); // will remove all the y from the end and x from the beggining

1. Anything but ECB.
2. If using CTR, it is imperative that you use a different IV for each message, otherwise you end up with the attacker being able to take two ciphertexts and deriving a combined unencrypted plaintext. The reason is that CTR mode essentially turns a block cipher into a stream cipher, and the first rule of stream ciphers is to never use the same Key+IV twice.
3. There really isn't much difference in how difficult the modes are to implement. Some modes only require the block cipher to operate in the encrypting direction. However, most block ciphers, including AES, don't take much more code to implement decryption.
4. For all cipher modes, it is important to use different IVs for each message if your messages could be identical in the first several bytes, and you don't want an attacker knowing this.

Like Scaffman said - You are missing quotes. Always when you are passing a value to varchar2 use quotes

INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');

So one (') starts the string and the second (') closes it.

But if you want to add a quote symbol into a string for example:

My father told me: 'you have to be brave, son'.

You have to use a triple quote symbol like:

'My father told me: ''you have to be brave, son''.'

*adding quote method can vary on different db engines

Ruby:

class String
    def is_palindrome?
        letters_only = gsub(/\W/,'').downcase
        letters_only == letters_only.reverse
    end
end

puts 'abc'.is_palindrome? # => false
puts 'aba'.is_palindrome? # => true
puts "Madam, I'm Adam.".is_palindrome? # => true

You want to use regexp_substr() for this. This should work for your example:

select regexp_substr(val, '[^/]+/[^/]+', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

Here, by the way, is the SQL Fiddle.

Oops. I missed the part of the question where it says the last delimiter. For that, we can use regex_replace() for the first part:

select regexp_replace(val, '/[^/]+$', '', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

And here is this corresponding SQL Fiddle.

I know this is an old question, but I am surprised that all answers ensure that the method exists and it is a function, when the OP does only want to check for existence. To know it is a function (as many have stated) you may use:

typeof myObj.prop2 === 'function'

But you may also use as a condition:

typeof myObj.prop2

Or even:

myObj.prop2

This is so because a function evaluates to true and undefined evaluates to false. So if you know that if the member exists it may only be a function, you can use:

if(myObj.prop2) {
  <we have prop2>
}

Or in an expression:

myObj.prop2 ? <exists computation> : <no prop2 computation>

You can just put it in on the file system. Eclipse will pick up the change on the next refresh. Click the folder and press F5 to refresh. BTW, make sure the file name does not have any capital letters... it will break android... and eclipse will let you know.

A simple way is to write:

-std=c++11

in the Other Options section of the compiler flags. You could do this on a per-project basis (Project -> Build Options), and/or set it as a default option in the Settings -> Compilers part.

Some projects may require -std=gnu++11 which is like C++11 but has some GNU extensions enabled.

If using g++ 4.9, you can use -std=c++14 or -std=gnu++14.

You can install ANT through macports or homebrew.

But if you want to do without 3rd party package managers, the problem can simply be fixed by downloading the binary release from the apache ANT web site and adding the binary to your system PATH.

For example, on Mountain Lion, in ~/.bash_profile and ~/.bashrc my path was setup like this:

export ANT_HOME="/usr/share/ant"
export PATH=$PATH:$ANT_HOME/bin

So after uncompressing apache-ant-1.9.2-bin.tar.bz2 I moved the resulting directory to /usr/share/ and renamed it ant.

Simple as that, the issue is fixed.

Note Don't forget to sudo chown -R root:wheel /usr/share/ant

This because the input that the user inserts into the JOptionPane is a String and it is stored and returned as a String.

Java cannot convert between strings and number by itself, you have to use specific functions, just use:

int ans = Integer.parseInt(JOptionPane.showInputDialog(...))

From the HTML 4 spec:

If a form contains more than one submit button, only the activated submit button is successful.

This means that given more than 1 submit button and none activated (clicked), none should be successful.

And I'd argue this makes sense: Imagine a huge form with multiple submit-buttons. At the top, there is a "delete this record"-button, then lots of inputs follow and at the bottom there is an "update this record"-button. A user hitting enter while in a field at the bottom of the form would never suspect that he implicitly hits the "delete this record" from the top.

Therefore I think it is not a good idea to use the first or any other button it the user does not define (click) one. Nevertheless, browsers are doing it of course.

I think you have to draw the listitems yourself to achieve this.

Here's a post with the same kind of question.

Looks like nobody mentioned

SET NAMES utf8;

I found this solution here and it helped me. How to apply it:

To be all UTF-8, issue the following statement just after you’ve made the connection to the database server: SET NAMES utf8;

Maybe this will help someone.

If your input always has a time zone of "zulu" ("Z" = UTC), then you can use DateTimeFormatter.ISO_INSTANT (implicitly):

final Instant parsed = Instant.parse(dateTime);

If time zone varies and has the form of "+01:00" or "+01:00:00" (when not "Z"), then you can use DateTimeFormatter.ISO_OFFSET_DATE_TIME:

DateTimeFormatter formatter = DateTimeFormatter.ISO_OFFSET_DATE_TIME;
final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter);

If neither is the case, you can construct a DateTimeFormatter in the same manner as DateTimeFormatter.ISO_OFFSET_DATE_TIME is constructed.

Your current pattern has several problems:

• not using strict mode (ResolverStyle.STRICT);
• using yyyy instead of uuuu (yyyy will not work in strict mode);
• using 12-hour hh instead of 24-hour HH;
• using only one digit S for fractional seconds, but input has three.

I got the same error for python 32 bit. After install 64bit, the problem was fixed.

Try this:

str.replace("\"", "\\\""); // (Escape backslashes and embedded double-quotes)

Or, use single-quotes to quote your search and replace strings:

str.replace('"', '\\"');   // (Still need to escape the backslash)

As pointed out by helmus, if the first parameter passed to .replace() is a string it will only replace the first occurrence. To replace globally, you have to pass a regex with the g (global) flag:

str.replace(/"/g, "\\\"");
// or
str.replace(/"/g, '\\"');

But why are you even doing this in JavaScript? It's OK to use these escape characters if you have a string literal like:

var str = "Dude, he totally said that \"You Rock!\"";

But this is necessary only in a string literal. That is, if your JavaScript variable is set to a value that a user typed in a form field you don't need to this escaping.

Regarding your question about storing such a string in an SQL database, again you only need to escape the characters if you're embedding a string literal in your SQL statement - and remember that the escape characters that apply in SQL aren't (usually) the same as for JavaScript. You'd do any SQL-related escaping server-side.

I use a wrapper around a Dictionary<T, object>, storing nulls in the values. This gives O(1) add, lookup and remove on the keys, and to all intents and purposes acts like a set.

public static void formatDouble(double myDouble){
 NumberFormat numberFormatter = new DecimalFormat("##.000");
 String result = numberFormatter.format(myDouble);
 System.out.println(result);
}

For instance, if the double value passed into the formatDouble() method is 345.9372, the following will be the result: 345.937 Similarly, if the value .7697 is passed to the method, the following will be the result: .770

#include<stdio.h>
struct examp{
int number;
};
struct examp a,*b=&a;`enter code here`
main()
{
a.number=5;
/* a.number,b->number,(*b).number produces same output. b->number is mostly used in linked list*/
   printf("%d \n %d \n %d",a.number,b->number,(*b).number);
}

output is 5 5 5

If you could not found run the command,

CentOS:

# yum install dos2unix*

# dos2unix filename.sh
dos2unix: converting file filename.sh to Unix format ...

Ubuntu / Debian:

# apt-get install dos2unix

pkill is the easiest command line utility

pkill -f node

or

pkill -f nodejs

whatever name the process runs as for your os

A wildcard * can be translated as .* or .*? regex pattern.

You might need to use a singleline mode to match newline symbols, and in this case, you can use (?s) as part of the regex pattern.

You can set it for the whole or part of the pattern:

X* = > @"X(?s:.*)"
*X = > @"(?s:.*)X"
*X* = > @"(?s).*X.*"
*X*YZ* = > @"(?s).*X.*YZ.*"
X*YZ*P = > @"(?s:X.*YZ.*P)"

If you don't want to modify current codes and just for debug usage.

Add this macro:

#define printf(args...) fprintf(stderr, ##args)
//under GCC
#define printf(args...) fprintf(stderr, __VA_ARGS__)
//under MSVC

Change stderr to stdout if you want to roll back.

It's helpful for debug, but it's not a good practice.

Perhaps not exactly what you asked, but I find this to be useful to put at the start of my programs:

import sys

if sys.version_info[0] < 3:
    raise Exception("Python 3 or a more recent version is required.")

Try

import platform
platform.python_version()

Should give you a string like "2.3.1". If this is not exactly waht you want there is a rich set of data available through the "platform" build-in. What you want should be in there somewhere.

If your window rootViewController is UITabbarController(which is in most cases) then you can access tabbar in didFinishLaunchingWithOptions in the AppDelegate file.

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
    // Override point for customization after application launch.

    if let tabBarController = self.window!.rootViewController as? UITabBarController {
        tabBarController.selectedIndex = 1
    }

    return true
}

This will open the tab with the index given (1) in selectedIndex.

If you do this in viewDidLoad of your firstViewController, you need to manage by flag or another way to keep track of the selected tab. The best place to do this in didFinishLaunchingWithOptions of your AppDelegate file or rootViewController custom class viewDidLoad.

In your script, this part:

document.getElementById('Noite')

must be returning null and you are also attempting to set the display property to an invalid value. There are a couple of possible reasons for this first part to be null.

1. You are running the script too early before the document has been loaded and thus the Noite item can't be found.

2. There is no Noite item in your HTML.

I should point out that your use of document.write() in this case code probably signifies a problem. If the document has already loaded, then a new document.write() will clear the old content and start a new fresh document so no Noite item would be found.

If your document has not yet been loaded and thus you're doing document.write() inline to add HTML inline to the current document, then your document has not yet been fully loaded so that's probably why it can't find the Noite item.

The solution is probably to put this part of your script at the very end of your document so everything before it has already been loaded. So move this to the end of your body:

document.getElementById('Noite').style.display='block';

And, make sure that there are no document.write() statements in javascript after the document has been loaded (because they will clear the previous document and start a new one).

In addition, setting the display property to "display" doesn't make sense to me. The valid options for that are "block", "inline", "none", "table", etc... I'm not aware of any option named "display" for that style property. See here for valid options for teh display property.

You can see the fixed code work here in this demo: http://jsfiddle.net/jfriend00/yVJY4/. That jsFiddle is configured to have the javascript placed at the end of the document body so it runs after the document has been loaded.

P.S. I should point out that your lack of braces for your if statements and your inclusion of multiple statements on the same line makes your code very misleading and unclear.

I'm having a really hard time figuring out what you're asking, but here's a cleaned up version of your code that works which you can also see working here: http://jsfiddle.net/jfriend00/QCxwr/. Here's a list of the changes I made:

1. The script is located in the body, but after the content that it is referencing.
2. I've added var declarations to your variables (a good habit to always use).
3. The if statement was changed into an if/else which is a lot more efficient and more self-documenting as to what you're doing.
4. I've added braces for every if statement so it absolutely clear which statements are part of the if/else and which are not.
5. I've properly closed the </dd> tag you were inserting.
6. I've changed style.display = ''; to style.display = 'block';.
7. I've added semicolons at the end of every statement (another good habit to follow).

The code:

@Column is not the appropriate annotation. You don't want to store a whole User or Question in a column. You want to create an association between the entities. Start by renaming Questions to Question, since an instance represents a single question, and not several ones. Then create the association:

@Entity
@Table(name = "UserAnswer")
public class UserAnswer {

    // this entity needs an ID:
    @Id
    @Column(name="useranswer_id")
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "question_id")
    private Question question;

    @Column(name = "response")
    private String response;

    //getter and setter 
}

The Hibernate documentation explains that. Read it. And also read the javadoc of the annotations.

Just spent a good few days trying to get this to work on High Sierra 10.13.1. The gdb 8.1 version from homebrew would not work no matter what I tried. Ended up installing gdb 8.0.1 via macports and this miraculously worked (after jumping through all of the other necessary hoops related to codesigning etc).

One additional issue is that in Eclipse you will get extraneous single quotes around all of your program arguments which can be worked around by providing the arguments inside .gdbinit instead.

I am now returning to setters and getters but I am also putting the getters and setters in the magic methos __get and __set. This way I have a default behavior when I do this

$class->var;

This will just call the getter I have set in the __get. Normally I will just use the getter directly but there are still some instances where this is just simpler.

Because Javascript changes very slowly. And that's because people upgrade browsers slowly.

Many Javascript libraries implement their own last() function. Use one!

I installed the Tensorflow 0.12rc from source, and the following command gives me the version info:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 2
python3 -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 3

The following figure shows the output:

You could use List inside the method and transform it to an array at the end. But i think if we talk about an max-value of 20, your code is faster.

    private Update BuildMetaData(MetaData[] nvPairs)
    {
        Update update = new Update();
        List<InputProperty> ip = new List<InputProperty>();
        for (int i = 0; i < nvPairs.Length; i++)
        {
            if (nvPairs[i] == null) break;
            ip[i] = new InputProperty();
            ip[i].Name = "udf:" + nvPairs[i].Name;
            ip[i].Val = nvPairs[i].Value;
        }
        update.Items = ip.ToArray();
        return update;
    }

The way you would do this and preserve the ordering of the array is by putting the array keys into a separate array, find and replace the key in that array and then combine it back with the values.

Here is a function that does just that:

function change_key( $array, $old_key, $new_key ) {

    if( ! array_key_exists( $old_key, $array ) )
        return $array;

    $keys = array_keys( $array );
    $keys[ array_search( $old_key, $keys ) ] = $new_key;

    return array_combine( $keys, $array );
}

I found the actual solution...There is a problem in invoking your service from the client.. check the following things.

1. Make sure all [datacontract], [datamember] attribute are placed properly i.e. make sure WCF is error free

2. The WCF client, either web.config or any window app config, make sure config entries are properly pointing to the right ones.. binding info, url of the service..etc..etc

Then above problem : tempuri issue is resolved.. it has nothing to do with namespace.. though you are sure you lived with default,

Hope it saves your number of hours!

This is an implementation of aforementioned StanLe's anwer, also fixing the case where his answer would produce no curve when using densities.

This replaces the existing but hidden hist.default() function, to only add the normalcurve parameter (which defaults to TRUE).

  if (plot == TRUE) {

}

Pseudo code, something like:

CASE
  When CHARINDEX('lactulose', dbo.Table.Column) > 0 Then 'BP Medication'
ELSE ''
END AS 'Medication Type'

This does not care where the keyword is found in the list and avoids depending on formatting of spaces and commas.

Why controllers are needed

The difference between link and controller comes into play when you want to nest directives in your DOM and expose API functions from the parent directive to the nested ones.

From the docs:

Best Practice: use controller when you want to expose an API to other directives. Otherwise use link.

Say you want to have two directives my-form and my-text-input and you want my-text-input directive to appear only inside my-form and nowhere else.

In that case, you will say while defining the directive my-text-input that it requires a controller from the parent DOM element using the require argument, like this: require: '^myForm'. Now the controller from the parent element will be injected into the link function as the fourth argument, following $scope, element, attributes. You can call functions on that controller and communicate with the parent directive.

Moreover, if such a controller is not found, an error will be raised.

Why use link at all

There is no real need to use the link function if one is defining the controller since the $scope is available on the controller. Moreover, while defining both link and controller, one does need to be careful about the order of invocation of the two (controller is executed before).

However, in keeping with the Angular way, most DOM manipulation and 2-way binding using $watchers is usually done in the link function while the API for children and $scope manipulation is done in the controller. This is not a hard and fast rule, but doing so will make the code more modular and help in separation of concerns (controller will maintain the directive state and link function will maintain the DOM + outside bindings).

Please refer to my answer on this post.

There is no need to iterate over the List just overwrite the equals method.

Use equals instead of ==

@Override
public boolean equals (Object object) {
    boolean result = false;
    if (object == null || object.getClass() != getClass()) {
        result = false;
    } else {
        EmployeeModel employee = (EmployeeModel) object;
        if (this.name.equals(employee.getName()) && this.designation.equals(employee.getDesignation())   && this.age == employee.getAge()) {
            result = true;
        }
    }
    return result;
}

Call it like this:

public static void main(String args[]) {

    EmployeeModel first = new EmployeeModel("Sameer", "Developer", 25);
    EmployeeModel second = new EmployeeModel("Jon", "Manager", 30);
    EmployeeModel third = new EmployeeModel("Priyanka", "Tester", 24);

    List<EmployeeModel> employeeList = new ArrayList<EmployeeModel>();
    employeeList.add(first);
    employeeList.add(second);
    employeeList.add(third);

    EmployeeModel checkUserOne = new EmployeeModel("Sameer", "Developer", 25);
    System.out.println("Check checkUserOne is in list or not");
    System.out.println("Is checkUserOne Preasent = ? " + employeeList.contains(checkUserOne));

    EmployeeModel checkUserTwo = new EmployeeModel("Tim", "Tester", 24);
    System.out.println("Check checkUserTwo is in list or not");
    System.out.println("Is checkUserTwo Preasent = ? " + employeeList.contains(checkUserTwo));

}

I would use cron to run a script every minute, and make that script run your script four times with a 15-second sleep between runs.

(That assumes your script is quick to run - you could adjust the sleep times if not.)

That way, you get all the benefits of cron as well as your 15 second run period.

Edit: See also @bmb's comment below.

debugger is a reserved keyword by EcmaScript and given optional semantics since ES5

As a result, it can be used not only in Chrome, but also Firefox and Node.js via node debug myscript.js.

The standard says:

Syntax

DebuggerStatement :
    debugger ;

Semantics

Evaluating the DebuggerStatement production may allow an implementation to cause a breakpoint when run under a debugger. If a debugger is not present or active this statement has no observable effect.

The production DebuggerStatement : debugger ; is evaluated as follows:

1. If an implementation defined debugging facility is available and enabled, then
   1. Perform an implementation defined debugging action.
   2. Let result be an implementation defined Completion value.
2. Else
   1. Let result be (normal, empty, empty).
3. Return result.

No changes in ES6.

Right here: http://jt400.sourceforge.net/

This is what I use for that exact purpose.

EDIT: Usage Examples (minus exceptions):

// Driver initialization
AS400JDBCDriver driver = new com.ibm.as400.access.AS400JDBCDriver();
DriverManager.registerDriver(driver);

// JDBC Connection URL
String url = "jdbc:as400://10.10.10.10" + ";promt=false" // disable GUI prompting by jt400 library

// Get a Connection object (this is used to create statements, etc)
Connection conn = DriverManager.getConnection(url, UserString, PassString);

Hope that helps!

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

A verbose equivalent is to combine $LASTEXITCODE and -eq 0:

msbuild.exe args; if ($LASTEXITCODE -eq 0) { echo 'it built'; } else { echo 'it failed'; }

I'm not sure why if ($?) didn't work for me, but this one did.

Try this

> dt.columns.Add("ColumnName", typeof(Give the type you want));
> dt.Rows[give the row no like  or  or any no]["Column name in which you want to add data"] = Value;

Apart from creating a custom template file and assigning that template to a page (like in the example in the accepted answer), there is also a way with the template naming convention that WordPress uses for loading templates (template hierarchy).

Create a new page and use the slug of that page for the template filename (create a template file named page-{slug}.php). WordPress will automatically load the template that fits to this rule.

I guess it would be best to fix the database startup script itself. But as a work around, you can add that line to /etc/rc.local, which is executed about last in init phase.

May this code help you. It works in my case.

$filename = "D:\xampp\htdocs\wordpress/wp-content/uploads/json/2018-10-25.json";
    $fileUrl = "http://localhost/wordpress/wp-content/uploads/json/2018-10-25.json";
    if(!file_exists($filename)):
        $handle = fopen( $filename, 'a' ) or die( 'Cannot open file:  ' . $fileUrl ); //implicitly creates file
        fwrite( $handle, json_encode(array()));
        fclose( $handle );
    endif;
    $response = file_get_contents($filename);
    $tempArray = json_decode($response);
    if(!empty($tempArray)):
        $count = count($tempArray) + 1;
    else:
        $count = 1;
    endif;
    $tempArray[] = array_merge(array("sn." => $count), $data);
    $jsonData = json_encode($tempArray);
    file_put_contents($filename, $jsonData);

Herman's solution works, but it can be simplified because Sqlite allows to store any value type on any field.

Here is a simpler version that uses one Value field declared as TEXT to store any value:

CREATE TEMP TABLE IF NOT EXISTS Variables (Name TEXT PRIMARY KEY, Value TEXT);

INSERT OR REPLACE INTO Variables VALUES ('VarStr', 'Val1');
INSERT OR REPLACE INTO Variables VALUES ('VarInt', 123);
INSERT OR REPLACE INTO Variables VALUES ('VarBlob', x'12345678');

SELECT Value
  FROM Variables
 WHERE Name = 'VarStr'
UNION ALL
SELECT Value
  FROM Variables
 WHERE Name = 'VarInt'
UNION ALL
SELECT Value
  FROM Variables
 WHERE Name = 'VarBlob';

You can use the -Q --help=target options:

gcc -march=native -Q --help=target ...

The -v option may also be of use.

You can see the documentation on the --help option here.

Apple mail has also been known to make an encoding error on text and csv attachments outbound. In essence it replaces line terminators with soft line breaks on each line, which look like =0D in the encoding. If the attachment is emailed to Outlook, Outlook sees the soft line breaks, removes the = then appends real line breaks i.e. 0D0A so you get 0D0D0A (cr cr lf) at the end of each line. The encoding should be =0D= if it is a mac format file (or any other flavour of unix) or =0D0A= if it is a windows format file.

If you are emailing out from apple mail (in at least mavericks or yosemite), making the attachment not a text or csv file is an acceptable workaround e.g. compress it.

The bug also exists if you are running a windows VM under parallels and email a txt file from there using apple mail. It is the email encoding. Form previous comments here, it looks like netscape had the same issue.

ideally we should never catch Error in our Java application as it is an abnormal condition. The application would be in abnormal state and could result in carshing or giving some seriously wrong result.

If the .project and .classpath are already committed, then they need to be removed from the index (but not the disk)

git rm --cached .project
git rm --cached .classpath

Then the .gitignore would work (and that file can be added and shared through clones).
For instance, this gitignore.io/api/eclipse file will then work, which does include:

# Eclipse Core      
.project

# JDT-specific (Eclipse Java Development Tools)     
.classpath

Note that you could use a "Template Directory" when cloning (make sure your users have an environment variable $GIT_TEMPLATE_DIR set to a shared folder accessible by all).
That template folder can contain an info/exclude file, with ignore rules that you want enforced for all repos, including the new ones (git init) that any user would use.

As commented by Abdollah

When you change the index, you need to commit the change and push it.
Then the file is removed from the repository. So the newbies cannot checkout the files .classpath and .project from the repo.

If you know the settings in advance you can define it in a single statement:

var defaultsettings = {
                        ajaxsettings : { "ak1" : "v1", "ak2" : "v2", etc. },
                        uisettings : { "ui1" : "v1", "ui22" : "v2", etc }
                      };

If you don't know the values in advance you can just define the top level object and then add properties:

var defaultsettings = { };
defaultsettings["ajaxsettings"] = {};
defaultsettings["ajaxsettings"]["somekey"] = "some value";

Or half-way between the two, define the top level with nested empty objects as properties and then add properties to those nested objects:

var defaultsettings = {
                        ajaxsettings : {  },
                        uisettings : {  }
                      };

defaultsettings["ajaxsettings"]["somekey"] = "some value";
defaultsettings["uisettings"]["somekey"] = "some value";

You can nest as deep as you like using the above techniques, and anywhere that you have a string literal in the square brackets you can use a variable:

var keyname = "ajaxsettings";
var defaultsettings = {};
defaultsettings[keyname] = {};
defaultsettings[keyname]["some key"] = "some value";

Note that you can not use variables for key names in the { } literal syntax.

You didn't specify your IDEA version. Before 9.0 use Build | Build Jars, in IDEA 9.0 use Project Structure | Artifacts.

The following revision seeks to more clearly delineate PHP's array_filer(), array_map(), and array_walk(), all of which originate from functional programming:

array_filter() filters out data, producing as a result a new array holding only the desired items of the former array, as follows:

<?php
$array = array(1, "apples",2, "oranges",3, "plums");

$filtered = array_filter( $array, "ctype_alpha");
var_dump($filtered);
?>

live code here

All numeric values are filtered out of $array, leaving $filtered with only types of fruit.

array_map() also creates a new array but unlike array_filter() the resulting array contains every element of the input $filtered but with altered values, owing to applying a callback to each element, as follows:

<?php

$nu = array_map( "strtoupper", $filtered);
var_dump($nu);
?>

live code here

The code in this case applies a callback using the built-in strtoupper() but a user-defined function is another viable option, too. The callback applies to every item of $filtered and thereby engenders $nu whose elements contain uppercase values.

In the next snippet, array walk() traverses $nu and makes changes to each element vis a vis the reference operator '&'. The changes occur without creating an additional array. Every element's value changes in place into a more informative string specifying its key, category and value.

<?php

$f = function(&$item,$key,$prefix) {
    $item = "$key: $prefix: $item";
}; 
array_walk($nu, $f,"fruit");
var_dump($nu);    
?>    

See demo

Note: the callback function with respect to array_walk() takes two parameters which will automatically acquire an element's value and its key and in that order, too when invoked by array_walk(). (See more here).

iframe doesn't have onclick event but we can implement this by using iframe's onload event and javascript like this...

function iframeclick() {
document.getElementById("theiframe").contentWindow.document.body.onclick = function() {
        document.getElementById("theiframe").contentWindow.location.reload();
    }
}


<iframe id="theiframe" src="youriframe.html" style="width: 100px; height: 100px;" onload="iframeclick()"></iframe>

I hope it will helpful to you....

You can use array.nbytes for numpy arrays, for example:

>>> import numpy as np
>>> from sys import getsizeof
>>> a = [0] * 1024
>>> b = np.array(a)
>>> getsizeof(a)
8264
>>> b.nbytes
8192

So I started experimenting with the different things that FileReader API had to offer and could create an IMG tag with a DATA URL.

Drawback: It doesn't work on mobile phones, but it works fine on Google Chrome.

$('input').change(function() {_x000D_
    _x000D_
    var fr = new FileReader;_x000D_
    _x000D_
    fr.onload = function() {_x000D_
        var img = new Image;_x000D_
        _x000D_
        img.onload = function() { _x000D_
//I loaded the image and have complete control over all attributes, like width and src, which is the purpose of filereader._x000D_

static_cast means that you can't accidentally const_cast or reinterpret_cast, which is a good thing.

There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..

At the very simplest, you would catch urllib2.URLError:

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    raise MyException("There was an error: %r" % e)

The following should capture the specific error raised when the connection times out:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    # For Python 2.6
    if isinstance(e.reason, socket.timeout):
        raise MyException("There was an error: %r" % e)
    else:
        # reraise the original error
        raise
except socket.timeout, e:
    # For Python 2.7
    raise MyException("There was an error: %r" % e)

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

I understand that the C syntax != is in SQL Server due to its Unix heritage (back in the Sybase SQL Server days, pre Microsoft SQL Server 6.5).

Apply the reverse function to the range to iterate backwards:

For Swift 1.2 and earlier:

// Print 10 through 1
for i in reverse(1...10) {
    println(i)
}

It also works with half-open ranges:

// Print 9 through 1
for i in reverse(1..<10) {
    println(i)
}

Note: reverse(1...10) creates an array of type [Int], so while this might be fine for small ranges, it would be wise to use lazy as shown below or consider the accepted stride answer if your range is large.

To avoid creating a large array, use lazy along with reverse(). The following test runs efficiently in a Playground showing it is not creating an array with one trillion Ints!

Test:

var count = 0
for i in lazy(1...1_000_000_000_000).reverse() {
    if ++count > 5 {
        break
    }
    println(i)
}

For Swift 2.0 in Xcode 7:

for i in (1...10).reverse() {
    print(i)
}

Note that in Swift 2.0, (1...1_000_000_000_000).reverse() is of type ReverseRandomAccessCollection<(Range<Int>)>, so this works fine:

var count = 0
for i in (1...1_000_000_000_000).reverse() {
    count += 1
    if count > 5 {
        break
    }
    print(i)
}

For Swift 3.0 reverse() has been renamed to reversed():

for i in (1...10).reversed() {
    print(i) // prints 10 through 1
}

A dictionary cannot be directly used as a data source, you should do more.

SortedDictionary<string, int> userCache =  UserCache.getSortedUserValueCache();
KeyValuePair<string, int> [] ar= new KeyValuePair<string,int>[userCache.Count];
userCache.CopyTo(ar, 0);
comboBox1.DataSource = ar; new BindingSource(ar, "Key"); //This line is causing the error
comboBox1.DisplayMember = "Value";
comboBox1.ValueMember = "Key";
