I've used Volomike's solution updated by Jessica. Just added a check to see if the element exists, and made it return blank in case it doesn't.

jQuery.fn.outerHTML = function() {
return $(this).length > 0 ? $(this).clone().wrap('<div />').parent().html() : '';
};

Of course, use it like:

$('table#buttons').outerHTML();

Just:

Timestamp timestamp = new Timestamp(long);
Date date = new Date(timestamp.getTime());

A functional approach to replacing an element of an array in javascript:

const replace = (array, index, ...items) => [...array.slice(0, index), ...items, ...array.slice(index + 1)];

There are 2 inputs you might have and you can also convert between them.

1. input: listOfDictionaries --> use @VikashSingh solution

example: [{"":{"...

The pd.DataFrame() needs a listOfDictionaries as input.

2. input: jsonStr --> use @JustinMalinchak solution

example: '{"":{"...

If you have jsonStr, you need an extra step to listOfDictionaries first. This is obvious as it is generated like:

jsonStr = json.dumps(listOfDictionaries)

Thus, switch back from jsonStr to listOfDictionaries first:

listOfDictionaries = json.loads(jsonStr)

There are lots of differences between ISO 8601 and RFC 3339. Here is some examples to give you an idea:

2020-12-09T16:09:53+00:00 is a date time value that is compliant both both standards.

2020-12-09 16:09:53+00:00 uses a space to separate the date and time. This is allowed by RFC 3339 but not allowed by ISO 8601.

2020-12-09T16:09:53-00:00 has a negative sign in the time offset. This is allowed by RFC 3339 but not allowed by ISO 8601.

20201209T160953Z omits the hyphens. This is allowed by ISO 8601 but not allowed by RFC 3339.

ISO 8601 allows for things like ordinal dates such as 2020-344 which represents the 344th day of year 2020. RFC 3339 doesn't allow for that.

For your questions:

Is one just an extension?

No. As shown above each standard supports syntax variations not supported by the the other standard. So one syntax is not a superset or an extension of the other.

Should I use one over the other?

Of course this depends on your scenario. A safe general strategy is to generate date time strings that are valid by both standards.

Another good general strategy is to use an existing standard library for parsing/formatting date time strings and not write custom implementations unless you are addressing a genuinely custom scenario.

Do I really need to care that bad?

Well, that's up to you. Most regular developers who deal with date time strings should have a high level understanding but don't need to dive into the details.

It's quite unclear how you are computing the size ("the size in debug mode"?").

Use printf():

printf("the size of c is %u\n", (unsigned int) sizeof c);

Normally you'd print a size_t value (which is the type sizeof returns) with %zu, but if you're using a pre-C99 compiler like Visual Studio that won't work.

You need to find the typedef statements in your code that define the custom names like uint8 and so on; those are not standard so nobody here can know how they're defined in your code.

New C code should use <stdint.h> which gives you uint8_t and so on.

As you want to specifically search for a wildcard character you need to escape that

This is done by adding the ESCAPE clause to your LIKE expression. The character that is specified with the ESCAPE clause will "invalidate" the following wildcard character.

You can use any character you like (just not a wildcard character). Most people use a \ because that is what many programming languages also use

So your query would result in:

select * 
from Manager
where managerid LIKE '\_%' escape '\'
and managername like '%\_%' escape '\';

But you can just as well use any other character:

select * 
from Manager
where managerid LIKE '#_%' escape '#'
and managername like '%#_%' escape '#';

Here is an SQLFiddle example: http://sqlfiddle.com/#!6/63e88/4

Somebody was asking about list of formatting mailing addresses, and I think this is what he was looking for...

Frank's Compulsive Guide to Postal Addresses: http://www.columbia.edu/~fdc/postal/ Doesn't help much with street-level issues, however.

My work uses a couple of tools to assist with this: - Lexis-Nexis services, including NCOA lookups (you'll get address standardization for "free") - "Melissa Data" http://www.melissadata.com

This will grab records with strings (in the fieldName column) that are 10 characters long:

 select * from table where length(fieldName)=10

Used solution from @sinan-kozak, except fixed a few bugs. Specifically, we shouldn't use View.MeasureSpec.UNSPECIFIED for both the width and height when calling measureScrapChild as that won't properly account for wrapped text in the child. Instead, we will pass through the width and height modes from the parent which will allow things to work for both horizontal and vertical layouts.

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.

At least in Postgres you can use the following statement:

SELECT EntityID, EntityName, EntityProfile IS NOT NULL AS HasProfile FROM Entity

It mostly depends on the (other) activity in the database. Operations like this effectively freeze the entire database for other sessions. Another consideration is the datamodel and the presence of constraints,triggers, etc.

My first approach is always: create a (temp) table with a structure similar to the target table (create table tmp AS select * from target where 1=0), and start by reading the file into the temp table. Then I check what can be checked: duplicates, keys that already exist in the target, etc.

Then I just do a "do insert into target select * from tmp" or similar.

If this fails, or takes too long, I abort it and consider other methods (temporarily dropping indexes/constraints, etc)

You can also override the deployment repository on the command line: -Darguments=-DaltDeploymentRepository=myreposid::default::http://my/url/releases

You can avoid duplicates and still run much faster than UNION DISTINCT (which is actually same as UNION) by running query like this:

SELECT * FROM mytable WHERE a=X UNION ALL SELECT * FROM mytable WHERE b=Y AND a!=X

Notice the AND a!=X part. This is much faster then UNION.

As @ganaraj mentioned AngularJS has dependency injection at its core. When building toy seed applications with and without RequireJS, I personally found RequireJS was probably overkill for most use cases.

That doesn't mean RequireJS is not useful for it's script loading capabilities and keeping your codebase clean during development. Combining the r.js optimizer (https://github.com/jrburke/r.js) with almond (https://github.com/jrburke/almond) can create a very slim script loading story. However since its dependency management features are not as important with angular at the core of your application, you can also evaluate other client side (HeadJS, LABjs, ...) or even server side (MVC4 Bundler, ...) script loading solutions for your particular application.

using System.Diagnostics;
...

var st = new StackTrace();
var sf = st.GetFrame(0);

var currentMethodName = sf.GetMethod();

Or, if you'd like to have a helper method:

[MethodImpl(MethodImplOptions.NoInlining)]
public string GetCurrentMethod()
{
    var st = new StackTrace();
    var sf = st.GetFrame(1);

    return sf.GetMethod().Name;
}

The best way is to begin coding with them. Design patterns are a great concept that are hard to apply from just reading about them. Take some sample implementations that you find online and build up around them.

A great resource is the Data & Object Factory page. They go over the patterns, and give you both conceptual and real world examples. Their reference material is great, too.

If you are using custom adapters than android:focusable="false" and android:focusableInTouchMode="false" are nessesury to make list items clickable while using checkbox.

<CheckBox
        android:id="@+id/checkbox_fav"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/checkbox_layout"/>

In drawable>checkbox_layout.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/uncked_checkbox"
        android:state_checked="false"/>
    <item android:drawable="@drawable/selected_checkbox"
        android:state_checked="true"/>
    <item android:drawable="@drawable/uncked_checkbox"/>
</selector>

Ok it looks like NPM is using your .gitignore as a base for the .npmignore file, and thus ignores /lib. If you add a blank .npmignore file into the root of your application, everything should work.

[edit] - more info on this behaviour here: https://docs.npmjs.com/misc/developers#keeping-files-out-of-your-package

I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;

It works and it's cross browser compatible.

Check out the code below, you probably get a better explanation:

jQuery('.close a, .bg', '#message').on('click', function() {_x000D_
  jQuery('#message').fadeOut();_x000D_
  return false;_x000D_
});

Last insert id means you can get inserted auto increment id by using this method in active record,

$this->db->insert_id() 
// it can be return insert id it is 
// similar to the mysql_insert_id in core PHP

You can refer this link you can find some more stuff.

Information from executing a query

The whole point of getting things out as IEnumerable is so you can lazily iterate over the contents. As such, there isn't really a concept of an index. What you are doing really doesn't make a lot of sense for an IEnumerable. If you need something that supports access by index, put it in an actual list or collection.

make sure you use the POST to insert the data. Actually you were using GET.

There is no such thing as a byte or short literal. You need to cast to short using (short)100

Rename the id of your ListView like this,

<ListView android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

Since you are using ListActivity your xml file must specify the keyword android while mentioning to a ID.

If you need a custom ListView then instead of Extending a ListActivity, you have to simply extend an Activity and should have the same id without the keyword android.

Quite an old article on mssqlcity attempts to explain the types of locks:

Shared locks are used for operations that do not change or update data, such as a SELECT statement.

Update locks are used when SQL Server intends to modify a page, and later promotes the update page lock to an exclusive page lock before actually making the changes.

Exclusive locks are used for the data modification operations, such as UPDATE, INSERT, or DELETE.

What it doesn't discuss are Intent (which basically is a modifier for these lock types). Intent (Shared/Exclusive) locks are locks held at a higher level than the real lock. So, for instance, if your transaction has an X lock on a row, it will also have an IX lock at the table level (which stops other transactions from attempting to obtain an incompatible lock at a higher level on the table (e.g. a schema modification lock) until your transaction completes or rolls back).

The concept of "sharing" a lock is quite straightforward - multiple transactions can have a Shared lock for the same resource, whereas only a single transaction may have an Exclusive lock, and an Exclusive lock precludes any transaction from obtaining or holding a Shared lock.

Another way without using the .form-control is this:

  $(".dropdown-menu li a").click(function(){
        $(this).parents(".btn-group").find('.btn').html($(this).text() + ' <span class="caret"></span>');
        $(this).parents(".btn-group").find('.btn').val($(this).data('value'));
      });

$(".dropdown-menu li a").click(function(){_x000D_
  $(this).parents(".btn-group").find('.btn').html($(this).text() + ' <span class="caret"></span>');_x000D_
  $(this).parents(".btn-group").find('.btn').val($(this).data('value'));_x000D_

This doesn't use jQuery UI, but does use jQuery, and may be useful for those who aren't using jQuery UI for whatever reason. Do it like so:

function showDialog(){
  $('#dialog').show();
  $('*').on('click',function(e){
    $('#zoomer').hide();
  });
}

$(document).ready(function(){

  showDialog();    

});

So, once I've shown a dialog, I add a click handler that only looks for the first click on anything.

Now, it would be nicer if I could get it to ignore clicks on anything on #dialog and its contents, but when I tried switching $('*') with $(':not("#dialog,#dialog *")'), it still detected #dialog clicks.

Anyway, I was using this purely for a photo lightbox, so it worked okay for that purpose.

An advance approach is using Kotlin Extension function

fun Context.getRawInput(@RawRes resourceId: Int): InputStream {
    return resources.openRawResource(resourceId)
}

One more interesting thing is extension function use that is defined in Closeable scope

For example you can work with input stream in elegant way without handling Exceptions and memory managing

fun Context.readRaw(@RawRes resourceId: Int): String {
    return resources.openRawResource(resourceId).bufferedReader(Charsets.UTF_8).use { it.readText() }
}

If it is because of the overhead in terms of creating objects, then it probably can't be sped up at all with SA.

If it is because it is loading up related objects, then you might be able to do something with lazy loading. Are there lots of objects being created due to references? (IE, getting a Company object also gets all of the related People objects).

You should be able to use the Application class in the same way as Winform apps do. Probably the easiest way to start a new project is to do what Marc suggested: create a new Winform project, and then change it in the options to a console application

Normally, encryption functions take

encrypt(const void *ptr, size_t bufferSize);

as arguments. You can pass c_str and length directly:

encrypt(strng.c_str(), strng.length());

This way, extra space is allocated or wasted.

It is the fault of Do.Something(). The best practice here would be to return an array of size 0 (that is possible) instead of a null.

What kind of data?

data: $('#myForm').serialize() + "&moredata=" + morevalue

The "data" parameter is just a URL encoded string. You can append to it however you like. See the API here.

To stop animation you may set such objectAnimator that do nothing, e.g.

first when manual flipping there is animation left to right:

flipper.setInAnimation(leftIn);
flipper.setOutAnimation(rightOut);

then when switching to auto flipping there's no animation

flipper.setInAnimation(doNothing);
flipper.setOutAnimation(doNothing);

doNothing = ObjectAnimator.ofFloat(flipper, "x", 0f, 0f).setDuration(flipperSwipingDuration);

Just leave out the "dot-slash" ./:

D:\Gesture Recognition\Gesture Recognition\Debug>"Gesture Recognition.exe"

Though, if you wanted to, you could use .\ and it would work.

D:\Gesture Recognition\Gesture Recognition\Debug>.\"Gesture Recognition.exe"

When you install third-party extensions you need to make sure that all the compilation parameters match:

• PHP version
• Architecture (32/64 bits)
• Compiler (VC9, VC10, VC11...)
• Thread safety

Common glitches includes:

• Editing the wrong php.ini file (that's typical with bundles); the right path is shown in phpinfo().
• Forgetting to restart Apache.

• Not being able to see the startup errors; those should show up in Apache logs, but you can also use the command line to diagnose it, e.g.:

  php -d display_startup_errors=1 -d error_reporting=-1 -d display_errors -c "C:\Path\To\php.ini" -m
  

If everything's right you should see sqlsrv in the command output and/or phpinfo() (depending on what SAPI you're configuring):

[PHP Modules]
bcmath
calendar
Core
[...]
SPL
sqlsrv
standard

public class MainActivity extends AppCompatActivity {

    private static final String YOUTUBE_ID = "ea4-5mrpGfE";

    private final YouTubeExtractor mExtractor = YouTubeExtractor.create();


    private Callback<YouTubeExtractionResult> mExtractionCallback = new Callback<YouTubeExtractionResult>() {
        @Override
        public void onResponse(Call<YouTubeExtractionResult> call, Response<YouTubeExtractionResult> response) {
            bindVideoResult(response.body());
        }

        @Override
        public void onFailure(Call<YouTubeExtractionResult> call, Throwable t) {
            onError(t);
        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


//        For android youtube extractor library  com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'
        mExtractor.extract(YOUTUBE_ID).enqueue(mExtractionCallback);

    }


    private void onError(Throwable t) {
        t.printStackTrace();
        Toast.makeText(MainActivity.this, "It failed to extract. So sad", Toast.LENGTH_SHORT).show();
    }


    private void bindVideoResult(YouTubeExtractionResult result) {

//        Here you can get download url link
        Log.d("OnSuccess", "Got a result with the best url: " + result.getBestAvailableQualityVideoUri());

        Toast.makeText(this, "result : " + result.getSd360VideoUri(), Toast.LENGTH_SHORT).show();
    }
}

You can get download link in bindVideoResult() method.

METHOD 2

Using this library android-youtubeExtractor

Add into gradle file

repositories {
    maven { url "https://jitpack.io" }
}

compile 'com.github.HaarigerHarald:android-youtubeExtractor:master-SNAPSHOT'

Here is the code for getting download url.

       String youtubeLink = "http://youtube.com/watch?v=xxxx";

    YouTubeUriExtractor ytEx = new YouTubeUriExtractor(this) {
        @Override
        public void onUrisAvailable(String videoId, String videoTitle, SparseArray<YtFile> ytFiles) {
            if (ytFiles != null) {
                int itag = 22;
// Here you can get download url
                String downloadUrl = ytFiles.get(itag).getUrl();
            }
        }
    };

    ytEx.execute(youtubeLink);

You should use monit, a standard unix tool that can monitor different things on the system and react accordingly.

From the docs: http://mmonit.com/monit/documentation/monit.html#pid_testing

check process checkqueue.py with pidfile /var/run/checkqueue.pid
       if changed pid then exec "checkqueue_restart.sh"

You can also configure monit to email you when it does do a restart.

You can install and use the pip-autoremove utility to remove a package plus unused dependencies.

# install pip-autoremove
pip install pip-autoremove
# remove "somepackage" plus its dependencies:
pip-autoremove somepackage -y

In two way ssl the client asks for servers digital certificate and server ask for the same from the client. It is more secured as it is both ways, although its bit slow. Generally we dont follow it as the server doesnt care about the identity of the client, but a client needs to make sure about the integrity of server it is connecting to.

You can directly set the content type like below:

res.writeHead(200, {'Content-Type': 'text/plain'});

For reference go through the nodejs Docs link.

Create an texview_design.xml file and populate it with the following code. Put it in res/drawable.

<shape xmlns:android="http://schemas.android.com/apk/res/android" >

        <solid android:color="#98AFC7" />

        <stroke
            android:width="2dp"
            android:color="#98AFC7" />

        <corners
            android:bottomLeftRadius="20dp"
            android:bottomRightRadius="20dp"
            android:topLeftRadius="20dp"
            android:topRightRadius="20dp" />

    </shape>

Then in your main XML file just add the following line for each TextView:

  android:background="@drawable/texview_design"

Second way (not recommended): Download this circle and place it in your drawable folder and then make it your TextView's background. and then set the gravity to center.

Then it will look like this:

    ` 
//Here is the example I used for get the field name also the field value
//Hope This will help to someone
TestModel model = new TestModel ("MyDate", "MyTime", "OUT");
//Get All the fields of the class
 Field[] fields = model.getClass().getDeclaredFields();
//If the field is private make the field to accessible true
fields[0].setAccessible(true);
//Get the field name
  System.out.println(fields[0].getName());
//Get the field value
System.out.println(fields[0].get(model));
`

Using ClipRRect you need to hardcode BorderRadius, so if you need complete circular stuff, use ClipOval instead.

ClipOval(
  child: Image.network(
    "image_url",
    height: 100,
    width: 100,
    fit: BoxFit.cover,
  ),
),

I tried the solution below, it works on my machine.

<context:property-placeholder location="classpath*:connection.properties" ignore-unresolvable="true" order="1" />

<context:property-placeholder location="classpath*:general.properties" order="2"/>

In case multiple elements are present in the Spring context, there are a few best practices that should be followed:

the order attribute needs to be specified to fix the order in which these are processed by Spring all property placeholders minus the last one (highest order) should have ignore-unresolvable=”true” to allow the resolution mechanism to pass to others in the context without throwing an exception

The link you gave does actually describe the differences, but it's buried at the bottom of the page:

http://www.cplusplus.com/reference/cstdio/fopen/

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

The conversion could be to normalize \r\n to \n (or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.

In the target's General tab, there is an Embedded Binaries field. When you add the framework there the crash is resolved.

Reference is here on Apple Developer Forums.

I am not 100% sure where all of the other suggestions are trying to go, but the issue is basically related to the extension that you have on the file. If you save the file as a Excel 97/2003 workbook it will not allow you to see all million rows. Create a new sheet and save it as a workbook and you will see all million. Note: the extension will be .xlsx

As per response "MismatchSenderId", this is a mismatch between FireBase and your local "google-services.json", you have to make sure that both manifests matches

In FireBase console you go to "YourProject > Project OverView > Cloud Messaging" you'll see the "SenderID" which MUST match with the "google-services.json" in your Android project.

Best thing you can do is download the final json file from "General" tab and place it in your project.

How to fill Matrix with zeros in OpenCV?

To fill a pre-existing Mat object with zeros, you can use Mat::zeros()

Mat m1 = ...;
m1 = Mat::zeros(1, 1, CV_64F);

To intialize a Mat so that it contains only zeros, you can pass a scalar with value 0 to the constructor:

Mat m1 = Mat(1,1, CV_64F, 0.0);
//                        ^^^^double literal

The reason your version failed is that passing 0 as fourth argument matches the overload taking a void* better than the one taking a scalar.

you can run something like this (paste the code bellow in a .bat, or if you want it to run interractively replace the %% by % :

for %%i in (c:\directory\*.xls) do ssconvert %%i %%i.xlsx

If you can run powershell it will be :

Get-ChildItem -Path c:\directory -filter *.xls | foreach {ssconvert $($_.FullName) $($_.baseName).xlsx }

I resolved a similar problem by border-color: inherit

, see:

<li style="border-color: <?php echo $hex ?>;">...</li>

li {
    border-width: 0;
}

li:before {
    content: '';
    display: inline-block;
    float: none;
    margin-right: 10px;
    border-width: 4px;
    border-style: solid;
    border-color: inherit;
}

You can simply specify a series of images like this:

\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}

This will produce three slides with the images A to C in exactly the same position.

First Look at this example :

The C code for a simple C program is given below

struct Foo {
    char a;
    int b;
    double c;
    } foo1,foo2;

void foo_assign(void)
{
    foo1 = foo2;
}
int main(/*char *argv[],int argc*/)
{
    foo_assign();
return 0;
}

The Equivalent ASM Code for foo_assign() is

00401050 <_foo_assign>:
  401050:   55                      push   %ebp
  401051:   89 e5                   mov    %esp,%ebp
  401053:   a1 20 20 40 00          mov    0x402020,%eax
  401058:   a3 30 20 40 00          mov    %eax,0x402030
  40105d:   a1 24 20 40 00          mov    0x402024,%eax
  401062:   a3 34 20 40 00          mov    %eax,0x402034
  401067:   a1 28 20 40 00          mov    0x402028,%eax
  40106c:   a3 38 20 40 00          mov    %eax,0x402038
  401071:   a1 2c 20 40 00          mov    0x40202c,%eax
  401076:   a3 3c 20 40 00          mov    %eax,0x40203c
  40107b:   5d                      pop    %ebp
  40107c:   c3                      ret    

As you can see that a assignment is simply replaced by a "mov" instruction in assembly, the assignment operator simply means moving data from one memory location to another memory location. The assignment will only do it for immediate members of a structures and will fail to copy when you have Complex datatypes in a structure. Here COMPLEX means that you cant have array of pointers ,pointing to lists.

An array of characters within a structure will itself not work on most compilers, this is because assignment will simply try to copy without even looking at the datatype to be of complex type.

Just for the heck of it, I tracked this down in the jQuery code. The .val() function currently starts at line 165 of attributes.js. Here's the relevant section, with my annotations:

val: function( value ) {
    var hooks, ret, isFunction,
        elem = this[0];

        /// NO ARGUMENTS, BECAUSE NOT SETTING VALUE
    if ( !arguments.length ) {

        /// IF NOT DEFINED, THIS BLOCK IS NOT ENTERED. HENCE 'UNDEFINED'
        if ( elem ) {
            hooks = jQuery.valHooks[ elem.type ] || jQuery.valHooks[ elem.nodeName.toLowerCase() ];

            if ( hooks && "get" in hooks && (ret = hooks.get( elem, "value" )) !== undefined ) {
                return ret;
            }

            ret = elem.value;

            /// IF IS DEFINED, JQUERY WILL CHECK TYPE AND RETURN APPROPRIATE 'EMPTY' VALUE
            return typeof ret === "string" ?
                // handle most common string cases
                ret.replace(rreturn, "") :
                // handle cases where value is null/undef or number
                ret == null ? "" : ret;
        }

        return;
    }

So, you'll either get undefined or "" or null -- all of which evaluate as false in if statements.

1. Go to "Microsoft Visual C++ Compiler for Python 2.7" and continue based on "System Requirements" (this is what I did to put below steps together).

2. Install setuptools (setuptools 6.0 or later is required for Python to automatically detect this compiler package) either by: pip install setuptools or download "Setuptools bootstrapping installer" source from, save this file somwhere on your filestystem as "ez_python.py" and install with: python ez_python.py

3. Install wheel (wheel is recommended for producing pre-built binary packages). You can install it with: pip install wheel

4. Open Windows elevated Command Prompt cmd.exe (with "Run as administrator") to install "Microsoft Visual C++ Compiler for Python 2.7" for all users. You can use following command to do so: msiexec /i C:\users\jozko\download\VCForPython27.msi ALLUSERS=1 just use your own path to file: msiexec /i <path to MSI> ALLUSERS=1

5. Now you should be able to install pycrypto with: pip install pycrypto

Change your code

word-wrap: break-word;

to

word-break:break-all;

Example

<table style="width: 100%;">_x000D_
  <tr>_x000D_
    <td>_x000D_
      <div style="word-break:break-all;">longtextwithoutspacelongtextwithoutspace Long Content, Long Content, Long Content, Long Content, Long Content, Long Content, Long Content, Long Content, Long Content, Long Content</div>_x000D_
    </td>_x000D_
    <td><span style="display: inline;">Short Content</span>_x000D_
    </td>_x000D_
  </tr>_x000D_
</table>

Here's a copy/paste-able extension method for IEnumerable

public static class EnumerableExtensions
{
    /// <summary>
    /// Searches for an element that matches the conditions defined by the specified predicate,
    /// and returns the zero-based index of the first occurrence within the entire <see cref="IEnumerable{T}"/>.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="list">The list.</param>
    /// <param name="predicate">The predicate.</param>
    /// <returns>
    /// The zero-based index of the first occurrence of an element that matches the conditions defined by <paramref name="predicate"/>, if found; otherwise it'll throw.
    /// </returns>
    public static int FindIndex<T>(this IEnumerable<T> list, Func<T, bool> predicate)
    {
        var idx = list.Select((value, index) => new {value, index}).Where(x => predicate(x.value)).Select(x => x.index).First();
        return idx;
    }
}

Enjoy.

I am using IIS and mysql (directly downloaded, without wamp or xampp) My php was installed in c:\php I was getting the error of "call to undefined function mysql_connect()" For me the change of extension_dir worked. This is what I did. In the php.ini, Originally, I had this line

; On windows: extension_dir = "ext"

I changed it to:

; On windows: extension_dir = "C:\php\ext"

And it worked. Of course, I did the other things also like uncommenting the dll extensions etc, as explained in others remarks.

For those of you, who doesn't like this monstrous new AClass[] { ... } syntax, here's some sugar:

public AClass[] c(AClass... arr) { return arr; }

Use this little function as you like:

AClass[] array;
...
array = c(object1, object2);

MiniDLNA uses inotify, which is a functionality within the Linux kernel, used to discover changes in specific files and directories on the file system. To get it to work, you need inotify support enabled in your kernel.

The notify_interval (notice the lack of a leading 'i'), as far as I can tell, is only used if you have inotify disabled. To use the notify_interval (ie. get the server to 'poll' the file system for changes instead of automatically being notified of them), you have to disable the inotify functionality.

This is how it looks in my /etc/minidlna.conf:

# set this to no to disable inotify monitoring to automatically discover new files
# note: the default is yes
inotify=yes

Make sure that inotify is enabled in your kernel.

If it's not enabled, and you don't want to enable it, a forced rescan is the way to force MiniDLNA to re-scan the drive.

You can use a span with 50% border radius.

 .mydot{_x000D_
     background: rgb(66, 183, 42);_x000D_
     border-radius: 50%;_x000D_
     display: inline-block;_x000D_
     height: 20px;_x000D_
     margin-left: 4px;_x000D_
     margin-right: 4px;_x000D_
     width: 20px;_x000D_
}    

<span class="mydot"></span>

<table align="center"></table>

This works for me.

I previously came up with a different workaround that doesn't use stored procedures, but instead uses a parameter table and some connection_id() magic.

EDIT (Copied up from comments)

create a table that contains a column called connection_id (make it a bigint). Place columns in that table for parameters for the view. Put a primary key on the connection_id. replace into the parameter table and use CONNECTION_ID() to populate the connection_id value. In the view use a cross join to the parameter table and put WHERE param_table.connection_id = CONNECTION_ID(). This will cross join with only one row from the parameter table which is what you want. You can then use the other columns in the where clause for example where orders.order_id = param_table.order_id.

A tool to use here is awk:

cat file | awk 'BEGIN{ found=0} /TERMINATE/{found=1}  {if (found) print }'

How does this work:

1. We set the variable 'found' to zero, evaluating false
2. if a match for 'TERMINATE' is found with the regular expression, we set it to one.
3. If our 'found' variable evaluates to True, print :)

The other solutions might consume a lot of memory if you use them on very large files.

Scope means the code context that performs the INSERT statement SCOPE_IDENTITY(), as opposed to the global scope of @@IDENTITY.

CREATE TABLE Foo(
  ID INT IDENTITY(1,1),
  Dummy VARCHAR(100)
)

CREATE TABLE FooLog(
  ID INT IDENTITY(2,2),
  LogText VARCHAR(100)
)
go
CREATE TRIGGER InsertFoo ON Foo AFTER INSERT AS
BEGIN
  INSERT INTO FooLog (LogText) VALUES ('inserted Foo')
  INSERT INTO FooLog (LogText) SELECT Dummy FROM inserted
END

INSERT INTO Foo (Dummy) VALUES ('x')
SELECT SCOPE_IDENTITY(), @@IDENTITY 

Gives different results.

You can use the two dots at the end of expression, too. See this example:

//*[title="50"]/..

As an update, for Angular 7, a very good example, loading plus http interceptor, here: https://nezhar.com/blog/create-a-loading-screen-for-angular-apps/.

For version 6, you need a small adjustment when you use Subject. You need to add the generic type.

loadingStatus: Subject<boolean> = new Subject();

I'm using angular material, so instead of a loading text, you can use mat-spinner.

<mat-spinner></mat-spinner>

Update: the code from the previous page will not complete work (regarding the interceptor part), but here you have the complete solution: https://github.com/nezhar/snypy-frontend

And as Miranda recommended into comments, here is also the solution:

The loading screen component:

loading-screen.component.ts

    import { Component, ElementRef, ChangeDetectorRef, OnDestroy, AfterViewInit } from '@angular/core';
import { Subscription } from 'rxjs';
import { LoadingScreenService } from '../services/loading-screen.service';

@Component({
  selector: 'app-loading-screen',
  templateUrl: './loading-screen.component.html',
  styleUrls: ['./loading-screen.component.css']
})
export class LoadingScreenComponent implements AfterViewInit, OnDestroy {

  loading: boolean = false;
  loadingSubscription: Subscription;

  constructor(
    private loadingScreenService: LoadingScreenService,
    private _elmRef: ElementRef,
    private _changeDetectorRef: ChangeDetectorRef
  ) { }

  ngAfterViewInit(): void {
    this._elmRef.nativeElement.style.display = 'none';
    this.loadingSubscription = this.loadingScreenService.loadingStatus.pipe().subscribe(
      (status: boolean) => {
        this._elmRef.nativeElement.style.display = status ? 'block' : 'none';
        this._changeDetectorRef.detectChanges();
      }
    );
  }

  ngOnDestroy() {
    console.log("inside destroy loading component");
    this.loadingSubscription.unsubscribe();
  }

}

loading-screen.component.html

<div id="overlay">
  <mat-spinner class="content"></mat-spinner>
</div>

loading-screen.component.css

  #overlay {
      position: fixed; /* Sit on top of the page content */
      display: block; /* Hidden by default */
      width: 100%; /* Full width (cover the whole page) */
      height: 100%; /* Full height (cover the whole page) */
      top: 0;
      left: 0;
      right: 0;
      bottom: 0;
      background-color: rgba(60, 138, 255, 0.1); /* Black background with opacity */
      opacity: 0.5;
      z-index: 2; /* Specify a stack order in case you're using a different order for other elements */
      cursor: progress; /* Add a pointer on hover */
  }

  .content {
      position: absolute;
      top: 50%;
      left: 50%;
      font-size: 50px;
      color: white;
      transform: translate(-50%, -50%);
      -ms-transform: translate(-50%, -50%);
  }

Don't forget to add the component to your root component. In my case, AppComponent

app.component.html

<app-loading-screen></app-loading-screen>

The service that will manage the component: loading-screen.service.ts

import { Injectable } from '@angular/core';
import { Subject } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class LoadingScreenService {

  constructor() { }

  private _loading: boolean = false;
  loadingStatus: Subject<boolean> = new Subject();

  get loading(): boolean {
    console.log("get loading: " + this._loading);
    return this._loading;
  }

  set loading(value) {
    console.log("get loading: " + value);
    this._loading = value;
    this.loadingStatus.next(value);
  }

  startLoading() {
    console.log("startLoading");
    this.loading = true;
  }

  stopLoading() {
    console.log("stopLoading");
    this.loading = false;
  }
}

Here is the http interceptor, which will show/hide the component, using the previous service.

loading-screen-interceptor.ts

import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpRequest, HttpHandler, HttpEvent } from '@angular/common/http';
import { LoadingScreenService } from '../services/loading-screen.service';
import { Observable } from 'rxjs';
import { finalize } from 'rxjs/operators';

@Injectable()
export class LoadingScreenInterceptor implements HttpInterceptor {

    activeRequests: number = 0;

    constructor(
        private loadingScreenService: LoadingScreenService
    ) { }

    intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

        console.log("inside interceptor");

        if (this.activeRequests === 0) {
            this.loadingScreenService.startLoading();
        }

        this.activeRequests++;

        return next.handle(request).pipe(
            finalize(() => {
                this.activeRequests--;
                if (this.activeRequests === 0) {
                    this.loadingScreenService.stopLoading();
                }
            })
        )
    };
}

And in your app.module.ts, don't forget to config the interceptor

providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: LoadingScreenInterceptor,
      multi: true
    }
  ]

This is a Pythonic way to do it:

import httplib
import yaml
c = httplib.HTTPConnection(address)
c.request('GET', url_path)
r = c.getresponse()
# get the date into a datetime object

You want to use %p to print a pointer. From the spec:

p The argument shall be a pointer to void. The value of the pointer is converted to a sequence of printing characters, in an implementation-defined manner.

And don't forget the cast, e.g.

printf("%p\n",(void*)&a);

Visio Professional has a database reverse-engineering feature if yiu create a database diagram. It's not free but is fairly ubiquitous in most companies and should be fairly easy to get.

Note that Visio 2003 does not play nicely with SQL2005 or SQL2008 for reverse engineering - you will need to get 2007.

I find it useful to understand the underlying tools. These are cl.exe (compiler) and link.exe (linker). You need to tell the compiler the signatures of the functions you want to call in the dynamic library (by including the library's header) and you need to tell the linker what the library is called and how to call it (by including the "implib" or import library).

This is roughly the same process gcc uses for linking to dynamic libraries on *nix, only the library object file differs.

Knowing the underlying tools means you can more quickly find the appropriate settings in the IDE and allows you to check that the commandlines generated are correct.

Example

Say A.exe depends B.dll. You need to include B's header in A.cpp (#include "B.h") then compile and link with B.lib:

cl A.cpp /c /EHsc
link A.obj B.lib

The first line generates A.obj, the second generates A.exe. The /c flag tells cl not to link and /EHsc specifies what kind of C++ exception handling the binary should use (there's no default, so you have to specify something).

If you don't specify /c cl will call link for you. You can use the /link flag to specify additional arguments to link and do it all at once if you like:

cl A.cpp /EHsc /link B.lib

If B.lib is not on the INCLUDE path you can give a relative or absolute path to it or add its parent directory to your include path with the /I flag.

If you're calling from cygwin (as I do) replace the forward slashes with dashes.

If you write #pragma comment(lib, "B.lib") in A.cpp you're just telling the compiler to leave a comment in A.obj telling the linker to link to B.lib. It's equivalent to specifying B.lib on the link commandline.

I had referenced this article and many others and did not find a clear cut concise response to help. I am offering my discovery, arrived at with some references from this thread, in the following:

Spring-Boot version: 1.3.5.RELEASE

Spring-Core version: 4.2.6.RELEASE

Dependency Management: Brixton.SR1

The following is the pertinent yaml excerpt:

tools:
  toolList:
    - 
      name: jira
      matchUrl: http://someJiraUrl
    - 
      name: bamboo
      matchUrl: http://someBambooUrl

I created a Tools.class:

@Component
@ConfigurationProperties(prefix = "tools")
public class Tools{
    private List<Tool> toolList = new ArrayList<>();
    public Tools(){
      //empty ctor
    }

    public List<Tool> getToolList(){
        return toolList;
    }

    public void setToolList(List<Tool> tools){
       this.toolList = tools;
    }
}

I created a Tool.class:

@Component
public class Tool{
    private String name;
    private String matchUrl;

    public Tool(){
      //empty ctor
    }

    public String getName(){
        return name;
    }

    public void setName(String name){
       this.name= name;
    }
    public String getMatchUrl(){
        return matchUrl;
    }

    public void setMatchUrl(String matchUrl){
       this.matchUrl= matchUrl;
    }

    @Override
    public String toString(){
        StringBuffer sb = new StringBuffer();
        String ls = System.lineSeparator();
        sb.append(ls);
        sb.append("name:  " + name);
        sb.append(ls);
        sb.append("matchUrl:  " + matchUrl);
        sb.append(ls);
    }
}

I used this combination in another class through @Autowired

@Component
public class SomeOtherClass{

   private Logger logger = LoggerFactory.getLogger(SomeOtherClass.class);

   @Autowired
   private Tools tools;

   /* excluded non-related code */

   @PostConstruct
   private void init(){
       List<Tool>  toolList = tools.getToolList();
       if(toolList.size() > 0){
           for(Tool t: toolList){
               logger.info(t.toString());
           }
       }else{
           logger.info("*****-----     tool size is zero     -----*****");
       }  
   }

   /* excluded non-related code */

}

And in my logs the name and matching url's were logged. This was developed on another machine and thus I had to retype all of the above so please forgive me in advance if I inadvertently mistyped.

I hope this consolidation comment is helpful to many and I thank the previous contributors to this thread!

Assuming that they are in the same server, try this:

SELECT *
INTO SecondDB.TableName
FROM FirstDatabase.TableName

This will create a new table and just copy the data from FirstDatabase.TableName to SecondDB.TableName and won't create foreign keys or indexes.

Surprised no one has suggested a yield solution:

public static IEnumerable<char> Alphabet()
{
    for (char letter = 'A'; letter <= 'Z'; letter++)
    {
        yield return letter;
    }
}

Example:

foreach (var c in Alphabet())
{
    Console.Write(c);
}

if you run the command "forever logs", you can see where are the logs files.

- Abstract class is one which can't be instantiated, i.e. its object cannot be created.

- Abstract method are method's declaration without its definition.

- A Non-abstract class can only have Non-abstract methods.

- An Abstract class can have both the Non-abstract as well as Abstract methods.

- If the Class has an Abstract method then the class must also be Abstract.

- An Abstract method must be implemented by the very first Non-Abstract sub-class.

- Abstract class in Design patterns are used to encapsulate the behaviors that keeps changing.

int ArraySize = 400;

int[] terms = new int[ArraySize];


for(int runs = 0; runs < ArraySize; runs++)
{

    terms[runs] = runs;

}

That would be how I'd code it.

Here's a multiple files version, based on Ivan Baev's answer.

The HTML

<input type="file" multiple id="gallery-photo-add">
<div class="gallery"></div>

JavaScript / jQuery

$(function() {
    // Multiple images preview in browser
    var imagesPreview = function(input, placeToInsertImagePreview) {

        if (input.files) {
            var filesAmount = input.files.length;

            for (i = 0; i < filesAmount; i++) {
                var reader = new FileReader();

                reader.onload = function(event) {
                    $($.parseHTML('<img>')).attr('src', event.target.result).appendTo(placeToInsertImagePreview);
                }

                reader.readAsDataURL(input.files[i]);
            }
        }

    };

    $('#gallery-photo-add').on('change', function() {
        imagesPreview(this, 'div.gallery');
    });
});

Requires jQuery 1.8 due to the usage of $.parseHTML, which should help with XSS mitigation.

This will work out of the box, and the only dependancy you need is jQuery.

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

It all depends how you use Java or C# enums. How you use it will dictate the solution you'll choose in Ruby.

Try the native Set type, for instance:

>> enum = Set['a', 'b', 'c']
=> #<Set: {"a", "b", "c"}>
>> enum.member? "b"
=> true
>> enum.member? "d"
=> false
>> enum.add? "b"
=> nil
>> enum.add? "d"
=> #<Set: {"a", "b", "c", "d"}>

Just like @mark 's answer, we can create a Snippets in Chrome DevTools, to override the default JavaScript. Finally, we can see what effects they have on the page.

try

with open(f"{os.path.dirname(sys.argv[0])}/data/test.csv", newline='') as f:

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

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

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

this is the code i use it but your apps must run with net version 3.5

private void txtRead_Click(object sender, EventArgs e)
        {
           // var filename = @"d:\shiptest.txt";

            openFileDialog1.InitialDirectory = "d:\\";
            openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
            DialogResult result = openFileDialog1.ShowDialog();
            if (result == DialogResult.OK)
            {
                if (openFileDialog1.FileName != "")
                {
                    var reader = ReadAsLines(openFileDialog1.FileName);

                    var data = new DataTable();

                    //this assume the first record is filled with the column names
                    var headers = reader.First().Split(',');
                    foreach (var header in headers)
                    {
                        data.Columns.Add(header);
                    }

                    var records = reader.Skip(1);
                    foreach (var record in records)
                    {
                        data.Rows.Add(record.Split(','));
                    }

                    dgList.DataSource = data;
                }
            }
        }

        static IEnumerable<string> ReadAsLines(string filename)
        {
            using (StreamReader reader = new StreamReader(filename))
                while (!reader.EndOfStream)
                    yield return reader.ReadLine();
        }

What I usually do for small collections is to create kind of parser/converter method like this

def convertSetToList(setName):
return list(setName)

Then I can use the new list and access by index number

userFields = convertSetToList(user)
name = request.json[userFields[0]]

As a list you will have all the other methods that you may need to work with

I just discovered that you can also use "-d ":

cut "-d "

Test

$ cat a
hello how are you
I am fine
$ cut "-d " -f2 a
how
am

Effects are always executed after the render phase is completed even if you setState inside the one effect, another effect will read the updated state and take action on it only after the render phase.

Having said that its probably better to take both actions in the same effect unless there is a possibility that b can change due to reasons other than changing a in which case too you would want to execute the same logic

I like the answer given here:

http://stupidpythonideas.blogspot.com/2013/08/defaultdict-vs-setdefault.html

In short, the decision (in non-performance-critical apps) should be made on the basis of how you want to handle lookup of empty keys downstream (viz. KeyError versus default value).

if you want split string by some chars you can use

#include<iostream>
#include<string>
#include<vector>
#include<iterator>
#include<sstream>
#include<string>

using namespace std;
void replaceOtherChars(string &input, vector<char> &dividers)
{
    const char divider = dividers.at(0);
    int replaceIndex = 0;
    vector<char>::iterator it_begin = dividers.begin()+1,
        it_end= dividers.end();
    for(;it_begin!=it_end;++it_begin)
    {
        replaceIndex = 0;
        while(true)
        {
            replaceIndex=input.find_first_of(*it_begin,replaceIndex);
            if(replaceIndex==-1)
                break;
            input.at(replaceIndex)=divider;
        }
    }
}
vector<string> split(string str, vector<char> chars, bool missEmptySpace =true )
{
    vector<string> result;
    const char divider = chars.at(0);
    replaceOtherChars(str,chars);
    stringstream stream;
    stream<<str;    
    string temp;
    while(getline(stream,temp,divider))
    {
        if(missEmptySpace && temp.empty())
            continue;
        result.push_back(temp);
    }
    return result;
}
int main()
{
    string str ="milk, pigs.... hot-dogs ";
    vector<char> arr;
    arr.push_back(' '); arr.push_back(','); arr.push_back('.');
    vector<string> result = split(str,arr);
    vector<string>::iterator it_begin= result.begin(),
        it_end= result.end();
    for(;it_begin!=it_end;++it_begin)
    {
        cout<<*it_begin<<endl;
    }
return 0;
}

you can write a generic method as (its too late but below code will help you/others)

public static FileInputStream getFile(File fileImport) throws IOException {
      FileInputStream fileStream = null;
    try {
        PrintWriter writer = new PrintWriter(fileImport);
        writer.print(StringUtils.EMPTY);
        fileStream = new FileInputStream(fileImport);
        } catch (Exception ex) {
            ex.printStackTrace();
        } finally {
            writer.close();
        }
         return fileStream;
}

This worked for me:

 BindingProvider bp = (BindingProvider) port;
 Map<String, Object> map = bp.getRequestContext();
 map.put(BindingProvider.USERNAME_PROPERTY, "aspbbo");
 map.put(BindingProvider.PASSWORD_PROPERTY, "9FFFN6P");

Fiddle of my solution is here. But just in case it expires I will paste the code as well.

HTML:

<select id="sel">
  <option value='1'>One</option>
  <option value='2'>Two</option>
  <option value='3'>Three</option>
</select>
<input type="button" id="button" value="Change option to 2" />

JS:

var sel = document.getElementById('sel'),
    button = document.getElementById('button');

button.addEventListener('click', function (e) {
    sel.options[1].selected = true;

    // firing the event properly according to StackOverflow
    // http://stackoverflow.com/questions/2856513/how-can-i-trigger-an-onchange-event-manually
    if ("createEvent" in document) {
        var evt = document.createEvent("HTMLEvents");
        evt.initEvent("change", false, true);
        sel.dispatchEvent(evt);
    }
    else {
        sel.fireEvent("onchange");
    }
});

sel.addEventListener('change', function (e) {
    alert('changed');
});

You can use embed player with opacity over on a cover photo with a right positioned play icon. After this you can check the activeElement of your document.

Of course I know this is not an optimal solution, but works on mobile devices too.

<div style="position: relative;">
   <img src="http://s3.amazonaws.com/content.newsok.com/newsok/images/mobile/play_button.png" style="position:absolute;top:0;left:0;opacity:1;" id="cover">
   <iframe width="560" height="315" src="https://www.youtube.com/embed/2qhCjgMKoN4?controls=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in- picture" allowfullscreen style="position: absolute;top:0;left:0;opacity:0;" id="player"></iframe>
 </div>
 <script>
   setInterval(function(){
      if(document.activeElement instanceof HTMLIFrameElement){
         document.getElementById('cover').style.opacity=0;
         document.getElementById('player').style.opacity=1;
       }
    } , 50);
  </script>

There is very simple way to plot all columns from a data frame using separate panels or the same panel:

plot.ts(data)

Which yields (where X1 - X4 are column names):

Have look at ?plot.ts for all the options.

If you wan't more control over your plotting function and not use a loop, you could also do something like:

par(mfcol = c(ncol(data), 1))
Map(function(x,y) plot(x, main =y), data, names(data))

Of course it's possible to create a foreign key relationship to a compound (more than one column) primary key. You didn't show us the statement you're using to try and create that relationship - it should be something like:

ALTER TABLE dbo.Content
   ADD CONSTRAINT FK_Content_Libraries
   FOREIGN KEY(LibraryID, Application)
   REFERENCES dbo.Libraries(ID, Application)

Is that what you're using?? If (ID, Application) is indeed the primary key on dbo.Libraries, this statement should definitely work.

Luk: just to check - can you run this statement in your database and report back what the output is??

SELECT
    tc.TABLE_NAME,
    tc.CONSTRAINT_NAME, 
    ccu.COLUMN_NAME
FROM 
    INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc
INNER JOIN 
    INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE ccu 
      ON ccu.TABLE_NAME = tc.TABLE_NAME AND ccu.CONSTRAINT_NAME = tc.CONSTRAINT_NAME
WHERE
    tc.TABLE_NAME IN ('Libraries', 'Content')

CREATE TABLE book (
   id INT AUTO_INCREMENT primary key NOT NULL,
   accepted_terms BIT(1) NOT NULL,
   accepted_privacy BIT(1) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Your syntax is incorrect. The var keyword in your for loop must be followed by a variable name, in this case its propName

var propValue;
for(var propName in nyc) {
    propValue = nyc[propName]

    console.log(propName,propValue);
}

I suggest you have a look here for some basics:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in

Using Angular you should add header to request or add it to module config headers: {'Content-Type': 'application/x-www-form-urlencoded'}

$http({
    url: url,
    method: method,
    timeout: timeout,
    data: data,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})

Add hidden reset button as follows

<input id="resetBtn" type="reset" value="reset" style="display:none" />
// Call reset buttons click event
// Similar to ClearInputs('resetBtn');
function ClearInputs(btnSelector) {
     var btn = $("#" + btnSelector);
     btn.click();
}

Yes. ArrayList is a sequential list. So, insertion and retrieval order is the same.

If you add elements during retrieval, the order will not remain the same.

Using the filter() function seems to work in your test cases (tested in Firefox). The selector would look like this:

$('#mySelect1 option').filter(function () {
    return $(this).text() === 'Banana';
});

You can also do:

obj = ClassModel.get_by_id(object_id)

This works, but there may I'm not sure if it's supported in Django 2.

The standard MIME type is application/pdf. The assignment is defined in RFC 3778, The application/pdf Media Type, referenced from the MIME Media Types registry.

MIME types are controlled by a standards body, The Internet Assigned Numbers Authority (IANA). This is the same organization that manages the root name servers and the IP address space.

The use of x-pdf predates the standardization of the MIME type for PDF. MIME types in the x- namespace are considered experimental, just as those in the vnd. namespace are considered vendor-specific. x-pdf might be used for compatibility with old software.

Easier way:

#required_number = 18

required_number=input("Insert a number: ")
while required_number != 18
    print("Oops! Something is wrong")
    required_number=input("Try again: ")
if required_number == '18'
    print("That's right!")

As of IE8, the full path is no longer sent to sites in the Internet Zone.

See the "File Upload Control" section at the end of this post: http://blogs.msdn.com/ie/archive/2008/07/02/ie8-security-part-v-comprehensive-protection.aspx for discussion.

Not 100% sure about the relationship between these two entities but here goes:

IList<Splitting> res = (from s in [data source]
                        where s.Customer.CompanyID == [companyID] &&
                              s.CustomerID == [customerID]
                        select s).ToList();

IList<Splitting> res = [data source].Splittings.Where(
                           x => x.Customer.CompanyID == [companyID] &&
                                x.CustomerID == [customerID]).ToList();

I can't comment yet, so I'm posting this as an answer. Best way to avoid reload is how @user2868288 said: using the onsubmit on the form tag.

From all the other possibilities mentioned here, it's the only way which allows the new HTML5 browser data input validation to be triggered (<button> won't do it nor the jQuery/JS handlers) and allows your jQuery/AJAX dynamic info to be appended on the page. For example:

<form id="frmData" onsubmit="return false">
 <input type="email" id="txtEmail" name="input_email" required="" placeholder="Enter a valid e-mail" spellcheck="false"/>
 <input type="tel" id="txtTel" name="input_tel" required="" placeholder="Enter your telephone number" spellcheck="false"/>
 <input type="submit" id="btnSubmit" value="Send Info"/>
</form>
<script type="text/javascript">
  $(document).ready(function(){
    $('#btnSubmit').click(function() {
        var tel = $("#txtTel").val();
        var email = $("#txtEmail").val();
        $.post("scripts/contact.php", {
            tel1: tel,
            email1: email
        })
        .done(function(data) {
            $('#lblEstatus').append(data); // Appends status
            if (data == "Received") {
                $("#btnSubmit").attr('disabled', 'disabled'); // Disable doubleclickers.
            }
        })
        .fail(function(xhr, textStatus, errorThrown) { 
            $('#lblEstatus').append("Error. Try later."); 
        });
     });
   }); 
</script>

Here's a simple extension method that returns a slice as a new array:

public static T[] Slice<T>(this T[] arr, uint indexFrom, uint indexTo) {
    if (indexFrom > indexTo) {
        throw new ArgumentOutOfRangeException("indexFrom is bigger than indexTo!");
    }

    uint length = indexTo - indexFrom;
    T[] result = new T[length];
    Array.Copy(arr, indexFrom, result, 0, length);

    return result;
}

Then you can use it as:

byte[] slice = foo.Slice(0, 40);

I use @Thiho answer but i get this error:

'git' is not recognized as an internal or external command

For solving that i use this steps:

I add the following paths to PATH:

• C:\Program Files\Git\bin\

• C:\Program Files\Git\cmd\

In windows 7:

1. Right-click "Computer" on the Desktop or Start Menu.
2. Select "Properties".
3. On the very far left, click the "Advanced system settings" link.
4. Click the "Environment Variables" button at the bottom.
5. Double-click the "Path" entry under "System variables".
6. At the end of "Variable value", insert a ; if there is not already one, and then C:\Program Files\Git\bin\;C:\Program Files\Git\cmd. Do not put a space between ; and the entry.

Finally close and re-open your console.

This is a recursive solution with n! which accepts duplicate elements in the string

import math

def getFactors(root,num):
    sol = []
    # return condition
    if len(num) == 1:
            return [root+num]
    # looping in next iteration
    for i in range(len(num)):  
        # Creating a substring with all remaining char but the taken in this iteration
        if i > 0:
            rem = num[:i]+num[i+1:]
        else:
            rem = num[i+1:]
        # Concatenating existing solutions with the solution of this iteration
        sol = sol + getFactors(root + num[i], rem)
    return sol

I validated the solution taking into account two elements, the number of combinations is n! and the result can not contain duplicates. So:

inpt = "1234"
results = getFactors("",inpt)

if len(results) == math.factorial(len(inpt)) | len(results) != len(set(results)):
    print("Wrong approach")
else:
    print("Correct Approach")

With Mongo 3.2 and higher just use your connection string as is:

mongo mongodb://username:[email protected]:10011/my_database

Below is an enhanced version of the source from the question and extended to cache multiple channel factories and attempt to look up the endpoint in the configuration file by contract name.

It uses .NET 4 (specifically: contravariance, LINQ, var):

/// <summary>

    /// <summary>

    /// </summary>
    private static readonly IDictionary<string, ChannelFactory<T>> cachedFactories =

    internal static void Use(UseServiceDelegate<T> codeBlock)
    {
        var factory = GetChannelFactory();
        var proxy = (IClientChannel)factory.CreateChannel();
        var success = false;

        try
        {
            using (proxy)
            {
                codeBlock((T)proxy);
            }

            success = true;
        }
        finally
        {
            if (!success)
            {
                proxy.Abort();
            }
        }
    }

            if (cachedFactories.ContainsKey(endpointName))
            {
                return cachedFactories[endpointName];
            }

            var factory = new ChannelFactory<T>(endpointName);

            cachedFactories.Add(endpointName, factory);
            return factory;
        }
    }

    /// <summary>

    private static string GetEndpointName()

        var fullName = type.FullName;

        lock (cachedFactories)
        {
            if (cachedEndpointNames.ContainsKey(type))
            {
                return cachedEndpointNames[type];
            }

            var serviceModel = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None).SectionGroups["system.serviceModel"] as ServiceModelSectionGroup;

            if ((serviceModel != null) && !string.IsNullOrEmpty(fullName))
            {
                foreach (var endpointName in serviceModel.Client.Endpoints.Cast<ChannelEndpointElement>().Where(endpoint => fullName.EndsWith(endpoint.Contract)).Select(endpoint => endpoint.Name))
                {
                    cachedEndpointNames.Add(type, endpointName);
                    return endpointName;
                }
            }
        }

        throw new InvalidOperationException("Could not find endpoint element for type '" + fullName + "' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.");
    }
}

I find that image mapping works pretty well. If you have any headers or footers that are images make sure that you apply a bgcolor="fill in the blank" because outlook in most cases wont load the image and you will be left with a transparent header. If you at least designate a color that works with the over all feel of the email it will be less of a shock for the user. Never try and use any styling sheets. Or CSS at all! Just avoid it.

Depending if you're copying content from a word or shared google Doc be sure to (command+F) Find all the (') and (") and replace them within your editing software (especially dreemweaver) because they will show up as code and it's just not good.

ALT is your best friend. use the ALT tag to add in text to all your images. Because odds are they are not going to load right. And that ALT text is what gets people to click the (see images) button. Also define your images Width, Height and make the boarder 0 so you dont get weird lines around your image.

Consider editing all images within Photoshop with a 15px boarder on each side (make background transparent and save as a PNG 24) of image. Sometimes the email clients do not read any padding styles that you apply to the images so it avoids any weird formatting!

Also i found the line under links particularly annoying so if you apply < style="text-decoration:none; color:#whatever color you want here!" > it will remove the line and give you the desired look.

There is alot that can really mess with the over all look and feel.

you can use PHP's end()

$array = array('a' => 1,'b' => 2,'c' => 3);
$lastElement = end($array);
foreach($array as $k => $v) {
    echo $v . '<br/>';
    if($v == $lastElement) {
         // 'you can do something here as this condition states it just entered last element of an array'; 
    }
}

Update1

as pointed out by @Mijoja the above could will have problem if you have same value multiple times in array. below is the fix for it.

$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
//point to end of the array
end($array);
//fetch key of the last element of the array.
$lastElementKey = key($array);
//iterate the array
foreach($array as $k => $v) {
    if($k == $lastElementKey) {
        //during array iteration this condition states the last element.
    }
}

Update2

I found solution by @onteria_ to be better then what i have answered since it does not modify arrays internal pointer, i am updating the answer to match his answer.

$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
// Get array keys
$arrayKeys = array_keys($array);
// Fetch last array key
$lastArrayKey = array_pop($arrayKeys);
//iterate array
foreach($array as $k => $v) {
    if($k == $lastArrayKey) {
        //during array iteration this condition states the last element.
    }
}

Thank you @onteria_

Update3

As pointed by @CGundlach PHP 7.3 introduced array_key_last which seems much better option if you are using PHP >= 7.3

$array = array('a' => 1,'b' => 2,'c' => 3);
$lastKey = array_key_last($array);
foreach($array as $k => $v) {
    echo $v . '<br/>';
    if($k == $lastKey) {
         // 'you can do something here as this condition states it just entered last element of an array'; 
    }
}

In addition to global "editor.rulers" setting, it's also possible to set this on a per-language level.

For example, style guides for Python projects often specify either 79 or 120 characters vs. Git commit messages should be no longer than 50 characters.

So in your settings.json, you'd put:

"[git-commit]": {"editor.rulers": [50]},
"[python]": {
    "editor.rulers": [
        79,
        120
    ]
}

In Notepad++ v. 6.4.1 is this possibility in:Settings->Preferences->Auto-Completion and there check Enable auto-completion on each input.

For auto-complete in code press Ctrl + Enter.

try this

json = $.grep(newcurrPayment.paymentTypeInsert, function (el, idx) { return el.FirstName == "Test1" }, true)

As mentioned by ecdpalma below, git 1.7.12+ (August 2012) has enhanced the option --root for git rebase:

"git rebase [-i] --root $tip" can now be used to rewrite all the history leading to "$tip" down to the root commit.

That new behavior was initially discussed here:

I personally think "git rebase -i --root" should be made to just work without requiring "--onto" and let you "edit" even the first one in the history.
It is understandable that nobody bothered, as people are a lot less often rewriting near the very beginning of the history than otherwise.

The patch followed.

(original answer, February 2010)

As mentioned in the Git FAQ (and this SO question), the idea is:

1. Create new temporary branch
2. Rewind it to the commit you want to change using git reset --hard
3. Change that commit (it would be top of current HEAD, and you can modify the content of any file)

4. Rebase branch on top of changed commit, using:

   git rebase --onto <tmp branch> <commit after changed> <branch>`
   

The trick is to be sure the information you want to remove is not reintroduced by a later commit somewhere else in your file. If you suspect that, then you have to use filter-branch --tree-filter to make sure the content of that file does not contain in any commit the sensible information.

In both cases, you end up rewriting the SHA1 of every commit, so be careful if you have already published the branch you are modifying the contents of. You probably shouldn’t do it unless your project isn’t yet public and other people haven’t based work off the commits you’re about to rewrite.

svn checkout --force svn://repo website.dir

then

svn revert -R website.dir

Will check out on top of existing files in website.dir, but not overwrite them. Then the revert will overwrite them. This way you do not need to take the site down to complete it.

Replace void *disconnectFunc; with void (*disconnectFunc)(); to declare function pointer type variable. Or even better use a typedef:

typedef void (*func_t)(); // pointer to function with no args and void return
...
func_t fptr; // variable of pointer to function
...
void D::setDisconnectFunc( func_t func )
{
    fptr = func;
}

void D::disconnected()
{
    fptr();
    connected = false;
}

Using MutationObserver can act like a callback for the jQuery append method:

I've explained it in another question, and this time I will only give example for modern browsers:

// Somewhere in your app:
var observeDOM = (() => {
    var MutationObserver = window.MutationObserver || window.WebKitMutationObserver;

    return function(obj, callback){
        if( MutationObserver ){
            // define a new observer
            var obs = new MutationObserver(function(mutations, observer){
                if( mutations[0].addedNodes.length || mutations[0].removedNodes.length )
                    callback(mutations);
            });
            // have the observer observe foo for changes in children
            obs.observe( obj, { childList:true, subtree:true });

            return obs;
        }
    }
})();

//////////////////
// Your code:

// setup the DOM observer (on the appended content's parent) before appending anything
observeDOM( document.body, ()=>{
    // something was added/removed
}).disconnect(); // don't listen to any more changes

// append something
$('body').append('<p>foo</p>');

The Prefix function is definitely the most efficient way of solving this problem, but you can also use for-in loops like the following:

let array = [1,2,3,4,5,6,7,8,9]
let maxNum = 5
var iterationNumber = 0
var firstNumbers = [Int()]
if array.count > maxNum{
  for i in array{
    iterationNumber += 1
    if iterationNumber <= maxNum{
      firstNumbers.append(i)
    }
  }
  firstNumbers.remove(at: 0)
  print(firstNumbers)
} else {
  print("There were not \(maxNum) items in the array.")
}

This solution takes up many lines of code but checks to see if there are enough items in the array to carry out the program, then continues and solves the problem. This solution uses many basic functions including array.count, which returns the amount of items in the array, not the position of last item in the array. It also uses array.append, which adds things onto the end of the array. Lastly, it uses array.remove, which removes the array's item that has a specified position.

I have tested it it and it works for at least swift 5.

It should look like this:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu')  # Last I checked this was necessary.
driver = webdriver.Chrome(CHROMEDRIVER_PATH, chrome_options=options)

This works for me using Python 3.6, I'm sure it'll work for 2.7 too.

Update 2018-10-26: These days you can just do this:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.headless = True
driver = webdriver.Chrome(CHROMEDRIVER_PATH, chrome_options=options)

Use CultureInfo class to change your culture info.

var dutchCultureInfo = CultureInfo.CreateSpecificCulture("nl-NL");
var date1 = DateTime.ParseExact(date, "dd.MM.yyyy HH:mm:ss", dutchCultureInfo);

If you are using Docker you need to make sure ports are exposed as well

As mentioned, PEP 8 says to use lower_case_with_underscores for variables, methods and functions.

I prefer using lower_case_with_underscores for variables and mixedCase for methods and functions makes the code more explicit and readable. Thus following the Zen of Python's "explicit is better than implicit" and "Readability counts"

The magic variables %n contains the arguments used to invoke the file: %0 is the path to the bat-file itself, %1 is the first argument after, %2 is the second and so on.

Since the arguments are often file paths, there is some additional syntax to extract parts of the path. ~d is drive, ~p is the path (without drive), ~n is the file name. They can be combined so ~dp is drive+path.

%~dp0 is therefore pretty useful in a bat: it is the folder in which the executing bat file resides.

You can also get other kinds of meta info about the file: ~t is the timestamp, ~z is the size.

Look here for a reference for all command line commands. The tilde-magic codes are described under for.

With newer versions of bundler you can use the clean task:

$ bundle help clean
Usage:
    bundle clean

Options:
    [--dry-run=only print out changes, do not actually clean gems]
    [--force=forces clean even if --path is not set]
    [--no-color=Disable colorization in output]
    -V, [--verbose=Enable verbose output mode]

Cleans up unused gems in your bundler directory
$ bundle clean --dry-run --force
Would have removed actionmailer (3.1.12)
Would have removed actionmailer (3.2.0.rc2)
Would have removed actionpack (3.1.12)
Would have removed actionpack (3.2.0.rc2)
Would have removed activemodel (3.1.12)
...

edit:

This is not recommended if you're using a global gemset (i.e. - all of your projects keep their gems in the same place). There're few ways to keep each project's gems separate, though:

1. rvm gemsets (http://rvm.io/gemsets/basics)
2. bundle install with any of the following options: --deployment or --path=<path> (http://bundler.io/v1.3/man/bundle-install.1.html)

Ok man, the only thing that worked for me was:

1. Change permissions of the key

   chmod 400 mykey.pem

2. Make sure to log in using ec2-user, and the correct ec2-99... address. The ec2-99 address is at the bottom of the aws console when you're logged in and seeing your instance listed

   ssh -i mykey.pem [email protected]

Here is the code, and you can decide which
(synchronized)StringBuffer or faster StringBuilder to use.

Benchmark shows StringBuilder is Faster.

public class Main {
            int times = 777;
            long t;

            {
                StringBuffer sb = new StringBuffer();
                t = System.currentTimeMillis();
                for (int i = times; i --> 0 ;) {
                    sb.append("");
                    getJSONFromStringBuffer(String stringJSON);
                }
                System.out.println(System.currentTimeMillis() - t);
            }

            {
                StringBuilder sb = new StringBuilder();
                t = System.currentTimeMillis();
                for (int i = times; i --> 0 ;) {
                     getJSONFromStringBUilder(String stringJSON);
                    sb.append("");
                }
                System.out.println(System.currentTimeMillis() - t);
            }
            private String getJSONFromStringBUilder(String stringJSONArray) throws JSONException {
                return new StringBuffer(
                       new JSONArray(stringJSONArray).getJSONObject(0).getString("phonetype"))
                           .append(" ")
                           .append(
                       new JSONArray(employeeID).getJSONObject(0).getString("cat"))
                      .toString();
            }
            private String getJSONFromStringBuffer(String stringJSONArray) throws JSONException {
                return new StringBuffer(
                       new JSONArray(stringJSONArray).getJSONObject(0).getString("phonetype"))
                           .append(" ")
                           .append(
                       new JSONArray(employeeID).getJSONObject(0).getString("cat"))
                      .toString();
            }
        }

You can use an inline if inside your ngStyle:

[ngStyle]="styleOne?{'background-color': 'red'} : {'background-color': 'blue'}"

A batter way in my opinion is to store your background color inside a variable and then set the background-color as the variable value:

[style.background-color]="myColorVaraible"

Now we can add a picture to Excel directly and easely. Just follow these instructions:

1. Go to the Insert tab.
2. Click on the Pictures option (it’s in the illustrations group).
3. In the ‘Insert Picture’ dialog box, locate the pictures that you want to insert into a cell in Excel.
4. Click on the Insert button.
5. Re-size the picture/image so that it can fit perfectly within the cell.
6. Place the picture in the cell. A cool way to do this is to first press the ALT key and then move the picture with the mouse. It will snap and arrange itself with the border of the cell as soon it comes close to it.

If you have multiple images, you can select and insert all the images at once (as shown in step 4).

You can also resize images by selecting it and dragging the edges. In the case of logos or product images, you may want to keep the aspect ratio of the image intact. To keep the aspect ratio intact, use the corners of an image to resize it.

When you place an image within a cell using the steps above, it will not stick with the cell in case you resize, filter, or hide the cells. If you want the image to stick to the cell, you need to lock the image to the cell it’s placed n.

To do this, you need to follow the additional steps as shown below.

1. Right-click on the picture and select Format Picture.
2. In the Format Picture pane, select Size & Properties and with the options in Properties, select ‘Move and size with cells’.

Now you can move cells, filter it, or hide it, and the picture will also move/filter/hide.

I had similar issues when trying to build amtk and utthpmock with jhbuild.

I needed to install the most recent version of autoconf-archive. Instructions are at https://github.com/autoconf-archive/autoconf-archive/blob/master/README-maint. I did an additional sudo make install at the end.

The last step was to update my ACLOCAL_PATH:

echo 'export ACLOCAL_PATH=$ACLOCAL_PATH:/usr/local/share/aclocal' >> ~/.bashrc

After a source ~/.bashrc, all the macros were finally found and the builds succeeded.

The Placeholder does not render any tags for itself, so it is great for grouping content without the overhead of outer HTML tags.

The Panel does have outer HTML tags but does have some cool extra properties.

• BackImageUrl: Gets/Sets the background image's URL for the panel

• HorizontalAlign: Gets/Sets the
  horizontal alignment of the parent's contents

• Wrap: Gets/Sets whether the
  panel's content wraps

There is a good article at startvbnet here.

Java lexicographically order:

1. Numbers -before-
2. Uppercase -before-
3. Lowercase

Odd as this seems, it is true...
I have had to write comparator chains to be able to change the default behavior.
Play around with the following snippet with better examples of input strings to verify the order (you will need JSE 8):

import java.util.ArrayList;

public class HelloLambda {

public static void main(String[] args) {
    ArrayList<String> names = new ArrayList<>();
    names.add("Kambiz");
    names.add("kambiz");
    names.add("k1ambiz");
    names.add("1Bmbiza");
    names.add("Samantha");
    names.add("Jakey");
    names.add("Lesley");
    names.add("Hayley");
    names.add("Benjamin");
    names.add("Anthony");

    names.stream().
        filter(e -> e.contains("a")).
        sorted().
        forEach(System.out::println);
}
}

Result

1Bmbiza
Benjamin
Hayley
Jakey
Kambiz
Samantha
k1ambiz

Spaces are horrible in filenames or directory names.

The correct syntax for this is to include every directory name that includes spaces, in double quotes

cmd /c C:\"Program Files"\"Microsoft Visual Studio 9.0"\Common7\IDE\devenv.com mysolution.sln /build "release|win32"

An example indicating the namespace:

String TheDocumentContent =
@"
<TheNamespace:root xmlns:TheNamespace = 'http://www.w3.org/2001/XMLSchema' >
   <TheNamespace:GrandParent>
      <TheNamespace:Parent>
         <TheNamespace:Child theName = 'Fred'  />
         <TheNamespace:Child theName = 'Gabi'  />
         <TheNamespace:Child theName = 'George'/>
         <TheNamespace:Child theName = 'Grace' />
         <TheNamespace:Child theName = 'Sam'   />
      </TheNamespace:Parent>
   </TheNamespace:GrandParent>
</TheNamespace:root>
";

XDocument TheDocument = XDocument.Parse( TheDocumentContent );

//Example 1:
var TheElements1 =
from
    AnyElement
in
    TheDocument.Descendants( "{http://www.w3.org/2001/XMLSchema}Child" )
select
    AnyElement;

ResultsTxt.AppendText( TheElements1.Count().ToString() );

//Example 2:
var TheElements2 =
from
    AnyElement
in
    TheDocument.Descendants( "{http://www.w3.org/2001/XMLSchema}Child" )
where
    AnyElement.Attribute( "theName" ).Value.StartsWith( "G" )
select
    AnyElement;

foreach ( XElement CurrentElement in TheElements2 )
{
    ResultsTxt.AppendText( "\r\n" + CurrentElement.Attribute( "theName" ).Value );
}

You will have to modify the below line:

<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>

modalRegister is the ID and hence requires a preceding # for ID reference in html.

So, the modified html code snippet would be as follows:

<li><a href="#" data-toggle="modal" data-target="#modalRegister">Register</a></li>

Where T2 is the table to which you're adding the constraint:

SELECT *
FROM T2
WHERE constrained_field NOT
IN (
    SELECT DISTINCT t.constrained_field
    FROM T2 
    INNER JOIN T1 t
    USING ( constrained_field )
)

And delete the results.

If you want N digits, add 10^N and delete the first digit.

for (( num=100; num<=105; num++ ))
do
  echo ${num:1:3}
done

Output:

01
02
03
04
05

These are really two questions.

The first one is answered here: Calling a Sub in VBA

To the second one, protip: there is no main subroutine in VBA. Forget procedural, general-purpose languages. VBA subs are "macros" - you can run them by hitting Alt+F8 or by adding a button to your worksheet and calling up the sub you want from the automatically generated "ButtonX_Click" sub.

If the server's certificate is self-signed, then this is working as designed and you will have to import the server's certificate into your keystore.

Assuming the server certificate is signed by a well-known CA, this is happening because the set of CA certificates available to a modern browser is much larger than the limited set that is shipped with the JDK/JRE.

The EasySSL solution given in one of the posts you mention just buries the error, and you won't know if the server has a valid certificate.

You must import the proper Root CA into your keystore to validate the certificate. There's a reason you can't get around this with the stock SSL code, and that's to prevent you from writing programs that behave as if they are secure but are not.

Try in2csv!

Usage:

in2csv file.xlsx > file.csv

Do something like this:

A <div> with ID of #imageDIV, another one with ID #download and a hidden <div> with ID #previewImage.

Include the latest version of jquery, and jspdf.debug.js from the jspdf CDN

Then add this script:

var element = $("#imageDIV"); // global variable
var getCanvas; // global variable
$('document').ready(function(){
  html2canvas(element, {
    onrendered: function (canvas) {
      $("#previewImage").append(canvas);
      getCanvas = canvas;
    }
  });
});
$("#download").on('click', function () {
  var imgageData = getCanvas.toDataURL("image/png");
  // Now browser starts downloading it instead of just showing it
  var newData = imageData.replace(/^data:image\/png/, "data:application/octet-stream");
  $("#download").attr("download", "image.png").attr("href", newData);
});

The div will be saved as a PNG on clicking the #download

If it's ok to use direct casting afterwards, I guess you can use the System.Enum base class in your method, wherever necessary. You just need to replace the type parameters carefully. So the method implementation would be like:

public static class EnumUtils
{
    public static Enum GetEnumFromString(string value, Enum defaultValue)
    {
        if (string.IsNullOrEmpty(value)) return defaultValue;
        foreach (Enum item in Enum.GetValues(defaultValue.GetType()))
        {
            if (item.ToString().ToLower().Equals(value.Trim().ToLower())) return item;
        }
        return defaultValue;
    }
}

Then you can use it like:

var parsedOutput = (YourEnum)EnumUtils.GetEnumFromString(someString, YourEnum.DefaultValue);

I have a cell which is linked to online stock database and updated frequently. I want to trigger a macro whenever the cell value is updated.

I believe this is similar to cell value change by a program or any external data update but above examples somehow do not work for me. I think the problem is because excel internal events are not triggered, but thats my guess.

I did the following,

Private Sub Worksheet_Change(ByVal Target As Range) 
  If Not Intersect(Target, Target.Worksheets("Symbols").Range("$C$3")) Is Nothing Then
   'Run Macro
End Sub

Length of an array:

UBound(columns)-LBound(columns)+1

UBound alone is not the best method for getting the length of every array as arrays in VBA can start at different indexes, e.g Dim arr(2 to 10)

UBound will return correct results only if the array is 1-based (starts indexing at 1 e.g. Dim arr(1 to 10). It will return wrong results in any other circumstance e.g. Dim arr(10)

More on the VBA Array in this VBA Array tutorial.

if you are having a problem as describe in this post:

After another hour or two I can actually answer my own question.

Someone on another forum mentioned that you need to keep a mention of plain ol' localhost in the httpd-vhost.conf file, so here's what I ended up with in there:

The method returns 1 if dateTimeA is greater than dateTimeB

The method returns 0 if dateTimeA equals dateTimeB

The method returns -1 if dateTimeA is less than dateTimeB

From the docs use sample():

In [79]: s = pd.Series([0,1,2,3,4,5])

# When no arguments are passed, returns 1 row.
In [80]: s.sample()
Out[80]:

Here's an utility function that I wrote to wrap the retry until success into a neater package. It uses the same basic structure, but prevents repetition. It could be modified to catch and rethrow the exception on the final try relatively easily.

def try_until(func, max_tries, sleep_time):
    for _ in range(0,max_tries):
        try:
            return func()
        except:
            sleep(sleep_time)
    raise WellNamedException()
    #could be 'return sensibleDefaultValue'

Can then be called like this

result = try_until(my_function, 100, 1000)

If you need to pass arguments to my_function, you can either do this by having try_until forward the arguments, or by wrapping it in a no argument lambda:

result = try_until(lambda : my_function(x,y,z), 100, 1000)

Below code worked for me

  $today_start = Carbon::now()->format('Y-m-d 00:00:00');
        $today_end = Carbon::now()->format('Y-m-d 23:59:59');

        $start_activity = MarketingActivity::whereBetween('created_at', [$today_start, $today_end])
                            ->orderBy('id', 'ASC')->limit(1)->get();

I realise this is an old post, but just in case anyone else is looking, you can use Contains by providing the case insensitive string equality comparer like so:

using System.Linq;

// ...

if (testList.Contains(keyword, StringComparer.OrdinalIgnoreCase))
{
    Console.WriteLine("Keyword Exists");
}

This has been available since .net 2.0 according to msdn.

// rename the .json file to .js and keep in src folder

Declare the json object as a variable

var customData = {
   "key":"value"
};

Export it using module.exports

module.exports = customData;

From the component that needs it, make sure to back out two folders deep

import customData from '../customData';

Hi in my case solutions here won't work My code:

index.js

import App from './App';

let store = createStore(App);

render(
    <Provider store={store}>
        <Router history={browserHistory}>
            <Route path="/" name='Strona glówna' component={App}>
                <IndexRoute name='' component={Welcome}/>
                <Route name='Dashboard' path="dashboard" component={ReatEstateList}/>

Error apeares in App.js after import

The best way to get number of rows from resultset is using count function query for database access and then rs.getInt(1) method to get number of rows. from my code look it:

    String query = "SELECT COUNT() FROM table";
ResultSet rs = new DatabaseConnection().selectData(query);
rs.getInt(1);

this will return int value number of rows fetched from database. Here DatabaseConnection().selectData() is my code for accessing database. I was also stuck here but then solved...

Set LDFLAGS and CFLAGS when you run make:

$ LDFLAGS="-L/home/me/local/lib" CFLAGS="-I/home/me/local/include" make

If you don't want to do that a gazillion times, export these in your .bashrc (or your shell equivalent). Also set LD_LIBRARY_PATH to include /home/me/local/lib:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/local/lib

You can try this way:-

Give a class say header to the header rows, use nextUntil to get all rows beneath the clicked header until the next header.

JS

$('.header').click(function(){
    $(this).nextUntil('tr.header').slideToggle(1000);
});

Html

<table border="0">
  <tr  class="header">
    <td colspan="2">Header</td>
  </tr>
  <tr>
    <td>data</td>
    <td>data</td>
  </tr>
  <tr>
    <td>data</td>
    <td>data</td>
  </tr>

Demo

Another Example:

$('.header').click(function(){
   $(this).find('span').text(function(_, value){return value=='-'?'+':'-'});
    $(this).nextUntil('tr.header').slideToggle(100); // or just use "toggle()"
});

Demo

You can also use promise to toggle the span icon/text after the toggle is complete in-case of animated toggle.

$('.header').click(function () {
    var $this = $(this);
    $(this).nextUntil('tr.header').slideToggle(100).promise().done(function () {
        $this.find('span').text(function (_, value) {
            return value == '-' ? '+' : '-'
        });
    });
});

.promise()

.slideToggle()

Or just with a css pseudo element to represent the sign of expansion/collapse, and just toggle a class on the header.

CSS:-

.header .sign:after{
  content:"+";
  display:inline-block;      
}
.header.expand .sign:after{
  content:"-";
}

JS:-

$(this).toggleClass('expand').nextUntil('tr.header').slideToggle(100);

Demo

When using moment.js, use:

var tz = moment.tz.guess();

It will return an IANA time zone identifier, such as America/Los_Angeles for the US Pacific time zone.

It is documented here.

Internally, it first tries to get the time zone from the browser using the following call:

Intl.DateTimeFormat().resolvedOptions().timeZone

If you are targeting only modern browsers that support this function, and you don't need Moment-Timezone for anything else, then you can just call that directly.

If Moment-Timezone doesn't get a valid result from that function, or if that function doesn't exist, then it will "guess" the time zone by testing several different dates and times against the Date object to see how it behaves. The guess is usually a good enough approximation, but not guaranteed to exactly match the time zone setting of the computer.

Am going to try and add value to this very good question and to build on @BrittonKerin's question in one of the comments under @David Wolever's fantastic answer. Wanted to share here because I had the same challenge as @BrittonKerin and I got something working (i.e. just want to run a piece of code only IF the table doesn't exist).

        # for completeness lets do the routine thing of connections and cursors
        conn = sqlite3.connect(db_file, timeout=1000) 

        cursor = conn.cursor() 

        # get the count of tables with the name  
        tablename = 'KABOOM' 
        cursor.execute("SELECT count(name) FROM sqlite_master WHERE type='table' AND name=? ", (tablename, ))

        print(cursor.fetchone()) # this SHOULD BE in a tuple containing count(name) integer.

        # check if the db has existing table named KABOOM
        # if the count is 1, then table exists 
        if cursor.fetchone()[0] ==1 : 
            print('Table exists. I can do my custom stuff here now.... ')
            pass
        else: 
           # then table doesn't exist. 
           custRET = myCustFunc(foo,bar) # replace this with your custom logic

You could match the port numbers from wireshark up to port numbers from, say, netstat which will tell you the PID of a process listening on that port.

TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)

Here is the FIX for 2.3 and below when using colours:

• Android: Entire ListView changes color on focus, not just ListView child item

As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape drawable containing the colour you want, and to use that instead of the colour.

I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).

fixing this on an ionic app, simply add

<preference name="loadUrlTimeoutValue" value="700000" />

to your config.xml file immediately after this line

<platform name="android">

Guava has a method Ints.asList() for creating a List<Integer> backed by an int[] array. You can use this with Collections.sort to apply the Comparator to the underlying array.

List<Integer> integersList = Ints.asList(arr);
Collections.sort(integersList, Collections.reverseOrder());

Note that the latter is a live list backed by the actual array, so it should be pretty efficient.

Typically if you have database connections or other objects declared that, whether used safely or created prior to your exception, will need to be cleaned up (disposed of), then returning your error handling code back to the ProcExit entry point will allow you to do your garbage collection in both cases.

If you drop out of your procedure by falling to Exit Sub, you may risk having a yucky build-up of instantiated objects that are just sitting around in your program's memory.

As suggested by Mark Ransom, I found the right encoding for that problem. The encoding was "ISO-8859-1", so replacing open("u.item", encoding="utf-8") with open('u.item', encoding = "ISO-8859-1") will solve the problem.

Maybe like me you set 'view engine' in express to an engine that doesn't exist, or tried to use an unregistered templating engine. Make sure that you use: app.engine('engine name',engine) app.set('view engine','engine name')

On windows 8, go to C:\Program Files\Java\jre7\bin and in the address bar, type "cmd" without the quotes. This will launch the terminal. Then type in string as describe here.

I came here looking for the answer to this on OSX. I ended up getting what I wanted with bash and awk:

topfiltered() {
  [[ -z "$1" ]] && return
  dump="/tmp/top_dump"
  rm -f "$dump"
  while :; do
    clear
    [[ -s "$dump" ]] && head -n $(( $LINES - 1 )) "$dump"
    top -l 1 -o cpu -ncols $(( $COLUMNS / 8 )) | awk -v p="$(pgrep -d ' ' $@)" '
        BEGIN { split(p, arr); for (k in arr) pids[arr[k]]=1 }
        NR<=12 || ($1 in pids)
    ' >"$dump"
  done
}

I loop top in logging mode and filter it with awk, building an associative array from the output of pgrep. Awk prints the first 12 lines, where line 12 is the column headers, and then every line which has a pid that's a key in the array. The dump file is used for a more watchable loop.

check this quick reminder of file path

Here is all you need to know about relative file paths:

• Starting with "/" returns to the root directory and starts there
• Starting with "../" moves one directory backwards and starts there
• Starting with "../../" moves two directories backwards and starts there (and so on...)
• To move forward, just start with the first subdirectory and keep moving forward

Update! - Behold Xcode 9 to the rescue! Now you can use cmd + to increase the fonts with Xcode 9. It took 5 Major releases for you to get it, Apple! But better late than never.

figured it out - however it was not very intuitive.

First some Pain Points

1. When You try to change the font size directly using edit -> format -> font, nothing happens! - Not a good UX ... moreover why play dumb when you can tell user that they are using default or "System-owned" theme and they cannot change it? - Bad Design and more bad UX ... Why keep this option (Cmd t) alive, which by the way is most standard way to increase font size across most well behaved mac apps, if you do not want user to change the font this way?

2. In Xcode preferences, when you try to change the font size by clicking on "fonts and colors", thats when XCode gives a pop-up saying what needs to be done. Also making a duplicate and then changing the fonts and colors is a lot of work rather than giving a button that says "Restore to Defaults" if Apple is so worried about the user messing up the default settings!

The solution is that - you need to duplicate the theme and then modify the copy you just made and apply that copy - phew!

DUAL is necessary in PL/SQL development for using functions that are only available in SQL

e.g.

DECLARE
x XMLTYPE;
BEGIN
SELECT xmlelement("hhh", 'stuff')
INTO x
FROM dual;
END;

Since they are both in the same solution, instead of adding a reference to the DLL, add a reference to the class library project itself (the Add Reference dialog will have a tab for this).

Ahh, it's a different solution. Missed that. How about you try instead of adding a reference to the project addding a reference to the compiled DLL of your class library. The Add Reference dialog has a Browse tab which does this.

Have a look at the ReadAsset.java from API samples that come with the SDK.

       try {
        InputStream is = getAssets().open("read_asset.txt");

        // We guarantee that the available method returns the total
        // size of the asset...  of course, this does mean that a single
        // asset can't be more than 2 gigs.
        int size = is.available();

        // Read the entire asset into a local byte buffer.
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();

        // Convert the buffer into a string.
        String text = new String(buffer);

        // Finally stick the string into the text view.
        TextView tv = (TextView)findViewById(R.id.text);
        tv.setText(text);

You should take decodeURI for it.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURI

As simple as this:

decodeURI('https://developer.mozilla.org/ru/docs/JavaScript_%D1%88%D0%B5%D0%BB%D0%BB%D1%8B');
// "https://developer.mozilla.org/ru/docs/JavaScript_?????"

Consider to use it inside try catch block for not missing an URIError.

Also it has full browsers support.

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

I'm guessing you didn't run this command after the commit failed so just actually run this to create the remote :

 git remote add origin https://github.com/VijayNew/NewExample.git

And the commit failed because you need to git add some files you want to track.

Update the create action as below:

def create
  ...
  respond_to do |format|
    if @reservation.save
      format.html do
        redirect_to '/'
      end
      format.json { render json: @reservation.to_json }
    else
      format.html { render 'new'} ## Specify the format in which you are rendering "new" page
      format.json { render json: @reservation.errors } ## You might want to specify a json format as well
    end
  end
end

You are using respond_to method but anot specifying the format in which a new page is rendered. Hence, the error ActionController::UnknownFormat .

Exception code 0xc0000005 is an Access Violation. An AV at fault offset 0x00000000 means that something in your service's code is accessing a nil pointer. You will just have to debug the service while it is running to find out what it is accessing. If you cannot run it inside a debugger, then at least install a third-party exception logger framework, such as EurekaLog or MadExcept, to find out what your service was doing at the time of the AV.

There can be a performance gain by importing variables/local scoping inside of a function. This depends on the usage of the imported thing inside the function. If you are looping many times and accessing a module global object, importing it as local can help.

test.py

X=10
Y=11
Z=12
def add(i):
  i = i + 10

runlocal.py

from test import add, X, Y, Z

    def callme():
      x=X
      y=Y
      z=Z
      ladd=add 
      for i  in range(100000000):
        ladd(i)
        x+y+z

    callme()

run.py

from test import add, X, Y, Z

def callme():
  for i in range(100000000):
    add(i)
    X+Y+Z

callme()

A time on Linux shows a small gain

/usr/bin/time -f "\t%E real,\t%U user,\t%S sys" python run.py 
    0:17.80 real,   17.77 user, 0.01 sys
/tmp/test$ /usr/bin/time -f "\t%E real,\t%U user,\t%S sys" python runlocal.py 
    0:14.23 real,   14.22 user, 0.01 sys

real is wall clock. user is time in program. sys is time for system calls.

The best tool I know is NodeJS tool: zeit/pkg

It is very easy to use (much more than Nexe, just as an example), you can just install in globally: npm install -g pkg

to create executables for macOS, Linux and Windows:

pkg exampleApp.js

I had a bit of complicated code which used NodeJS socket server, I tried different applications, none of them created it properly, except zeit/pkg.

You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.

And yes you can add header something like this way:

LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

• Make sure the file exists: use os.listdir() to see the list of files in the current working directory
• Make sure you're in the directory you think you're in with os.getcwd() (if you launch your code from an IDE, you may well be in a different directory)
• You can then either:
  • Call os.chdir(dir), dir being the folder where the file is located, then open the file with just its name like you were doing.
  • Specify an absolute path to the file in your open call.
• Remember to use a raw string if your path uses backslashes, like so: dir = r'C:\Python32'
  • If you don't use raw-string, you have to escape every backslash: 'C:\\User\\Bob\\...'
  • Forward-slashes also work on Windows 'C:/Python32' and do not need to be escaped.

Let me clarify how Python finds files:

• An absolute path is a path that starts with your computer's root directory, for example 'C:\Python\scripts..' if you're on Windows.
• A relative path is a path that does not start with your computer's root directory, and is instead relative to something called the working directory. You can view Python's current working directory by calling os.getcwd().

If you try to do open('sortedLists.yaml'), Python will see that you are passing it a relative path, so it will search for the file inside the current working directory. Calling os.chdir will change the current working directory.

Example: Let's say file.txt is found in C:\Folder.

To open it, you can do:

os.chdir(r'C:\Folder')
open('file.txt') #relative path, looks inside the current working directory

or

open(r'C:\Folder\file.txt') #full path

This works with SQL 2000:

    WHERE   ra.id -
    (

    ) BETWEEN 0 AND 1
