Adding to the accepted answer, I would say that implementing a correct multi producers / multi consumers queue is difficult (easier since C++11, though)

I would suggest you to try the (very good) lock free boost library, the "queue" structure will do what you want, with wait-free/lock-free guarantees and without the need for a C++11 compiler.

I am adding this answer now because the lock-free library is quite new to boost (since 1.53 I believe)

You might need to install SQL Server 2008 SP3.

SQL Server 2008 Service Pack 3

SQL Server 2012 Configuration Manager WMI Error – Remote Procedure call failed [0x800706be]

Try setting the core.autocrlf configuration option to true. Also have a look at the core.safecrlf option.

Actually it sounds like core.safecrlf might already be set in your repository, because (emphasis mine):

If this is not the case for the current setting of core.autocrlf, git will reject the file.

If this is the case, then you might want to check that your text editor is configured to use line endings consistently. You will likely run into problems if a text file contains a mixture of LF and CRLF line endings.

Finally, I feel that the recommendation to simply "use what you're given" and use LF terminated lines on Windows will cause more problems than it solves. Git has the above options to try to handle line endings in a sensible way, so it makes sense to use them.

A little bit off topic but useful is the pythonic numpy approach. Its robust and fast but just does compare pixels and not the objects or data the picture contains (and it requires images of same size and shape):

A very simple and fast approach to do this without openCV and any library for computer vision is to norm the picture arrays by

import numpy as np
picture1 = np.random.rand(100,100)
picture2 = np.random.rand(100,100)
picture1_norm = picture1/np.sqrt(np.sum(picture1**2))
picture2_norm = picture2/np.sqrt(np.sum(picture2**2))

After defining both normed pictures (or matrices) you can just sum over the multiplication of the pictures you like to compare:

1) If you compare similar pictures the sum will return 1:

In[1]: np.sum(picture1_norm**2)
Out[1]: 1.0

2) If they aren't similar, you'll get a value between 0 and 1 (a percentage if you multiply by 100):

In[2]: np.sum(picture2_norm*picture1_norm)
Out[2]: 0.75389941124629822

Please notice that if you have colored pictures you have to do this in all 3 dimensions or just compare a greyscaled version. I often have to compare huge amounts of pictures with arbitrary content and that's a really fast way to do so.

Works perfectly fine if the first option's value is null. Explanation : The HTML5 will read a null value on button submit. If not null (value attribute), the selected value is assumed not to be null hence the validation would have worked i.e by checking if there's been data in the option tag. Therefore it will not produce the validation method. However, i guess the other side becomes clear, if the value attribute is set to null ie (value = "" ), HTML5 will detect an empty value on the first or rather the default selected option thus giving out the validation message. Thanks for asking. Happy to help. Glad to know if i did.

You can go to fullscreen when user allows it :)

<button id="goFS">Go fullscreen</button>
<script>
  var goFS = document.getElementById("goFS");
  goFS.addEventListener("click", function() {
      
   const elem = document.documentElement;
   if (elem.requestFullscreen) {elem.requestFullscreen()}
   
  }, false);
</script>

I tried several of the suggestions above and unfortunately none of them worked. We have a "Log" index in our lower environment where apps write their errors. It is a single node cluster. What solved it for me was checking the YML configuration file for the node and seeing that it still had the default setting "gateway.expected_nodes: 2". This was overriding any other settings we had. Whenever we would create an index on this node it would try to spread 3 out of 5 shards to the phantom 2nd node. These would therefore appear as unassigned and they could never be moved to the 1st and only node.

The solution was editing the config, changing the setting "gateway.expected_nodes" to 1, so it would quit looking for its never-to-be-found brother in the cluster, and restarting the Elastic service instance. Also, I had to delete the index, and create a new one. After creating the index, the shards all showed up on the 1st and only node, and none were unassigned.

# Set how many nodes are expected in this cluster. Once these N nodes
# are up (and recover_after_nodes is met), begin recovery process immediately
# (without waiting for recover_after_time to expire):
#
# gateway.expected_nodes: 2
gateway.expected_nodes: 1

System.Int32.MaxValue

Assuming you mean System.Array, ie. any normally defined array (int[], etc). This is the maximum number of values the array can hold. The size of each value is only limited by the amount of memory or virtual memory available to hold them.

This limit is enforced because System.Array uses an Int32 as it's indexer, hence only valid values for an Int32 can be used. On top of this, only positive values (ie, >= 0) may be used. This means the absolute maximum upper bound on the size of an array is the absolute maximum upper bound on values for an Int32, which is available in Int32.MaxValue and is equivalent to 2^31, or roughly 2 billion.

On a completely different note, if you're worrying about this, it's likely you're using alot of data, either correctly or incorrectly. In this case, I'd look into using a List<T> instead of an array, so that you are only using as much memory as needed. Infact, I'd recommend using a List<T> or another of the generic collection types all the time. This means that only as much memory as you are actually using will be allocated, but you can use it like you would a normal array.

The other collection of note is Dictionary<int, T> which you can use like a normal array too, but will only be populated sparsely. For instance, in the following code, only one element will be created, instead of the 1000 that an array would create:

Dictionary<int, string> foo = new Dictionary<int, string>();
foo[1000] = "Hello world!";
Console.WriteLine(foo[1000]);

Using Dictionary also lets you control the type of the indexer, and allows you to use negative values. For the absolute maximal sized sparse array you could use a Dictionary<ulong, T>, which will provide more potential elements than you could possible think about.

Though @chrisb's accepted answer does answer the question, I would like to add to it the following.

A simple method I use to get the nth data or drop the nth row is the following:

df1 = df[df.index % 3 != 0]  # Excludes every 3rd row starting from 0
df2 = df[df.index % 3 == 0]  # Selects every 3rd raw starting from 0

This arithmetic based sampling has the ability to enable even more complex row-selections.

This assumes, of course, that you have an index column of ordered, consecutive, integers starting at 0.

I have the same problem bu no solution yet. page-break-inside does not work on browsers but Opera. An alternative might be to use page-break-after: avoid; on all child elements of the div to keep togehter ... but in my tests, the avoid-Attribute does not work eg. in Firefox ...

What works in all ppular browsers are forced page breaks using eg. page-break-after: always

I saw a great article from CSS-Tricks. It works just fine:

body {
    font-size: calc([minimum size] + ([maximum size] - [minimum size]) * ((100vw -
    [minimum viewport width]) / ([maximum viewport width] - [minimum viewport width])));
}

For example:

body {
    font-size: calc(14px + (26 - 14) * ((100vw - 300px) / (1600 - 300)));
}

We can apply the same equation to the line-height property to make it change with the browser as well.

body {
    font-size: calc(14px + (26 - 14) * ((100vw - 300px) / (1600 - 300)));
    line-height: calc(1.3em + (1.5 - 1.2) * ((100vw - 300px)/(1600 - 300)));
}

Sounds like the "...and I jump line by line..." part is wrong. Do you StepOver or StepIn and are you sure you don't accidentally miss the relevant call?

That said, debugging frameworks can be tedious for exactly this reason. To alleviate the problem, you can enable the "Enable frameworks debugging support" experiment. Happy debugging! :)

You can do this by adding them to the locals object in a general middleware.

app.use(function (req, res, next) {
   res.locals = {
     siteTitle: "My Website's Title",
     pageTitle: "The Home Page",
     author: "Cory Gross",
     description: "My app's description",
   };
   next();
});

Locals is also a function which will extend the locals object rather than overwriting it. So the following works as well

res.locals({
  siteTitle: "My Website's Title",
  pageTitle: "The Home Page",
  author: "Cory Gross",
  description: "My app's description",
});

Full example

var app = express();

var middleware = {

    render: function (view) {
        return function (req, res, next) {
            res.render(view);
        }
    },

    globalLocals: function (req, res, next) {
        res.locals({ 
            siteTitle: "My Website's Title",
            pageTitle: "The Root Splash Page",
            author: "Cory Gross",
            description: "My app's description",
        });
        next();
    },

    index: function (req, res, next) {
        res.locals({
            indexSpecificData: someData
        });
        next();
    }

};


app.use(middleware.globalLocals);
app.get('/', middleware.index, middleware.render('home'));
app.get('/products', middleware.products, middleware.render('products'));

I also added a generic render middleware. This way you don't have to add res.render to each route which means you have better code reuse. Once you go down the reusable middleware route you'll notice you will have lots of building blocks which will speed up development tremendously.

You can get the form using a document.getElementById and returning the elements[] array.

Here is an example.

You can also get each field of the form and get its value using the document.getElementById function and passing in the field's id.

Here you can find a working example, with some more suggestions about dynamic resizing of the list.

I've used display:inline-block and a percentage padding so that the parent list can dynamically change size:

display:inline-block;
padding:10px 1%;
width: 30%

plus two more rules to remove padding for the first and last items.

ul#menuItems li:first-child{padding-left:0;}
ul#menuItems li:last-child{padding-right:0;}

For those who are searching custom border and shape of ImageView. You can use android-shape-imageview

Just add compile 'com.github.siyamed:android-shape-imageview:0.9.+@aar' to your build.gradle.

And use in your layout.

<com.github.siyamed.shapeimageview.BubbleImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/neo"
    app:siArrowPosition="right"
    app:siSquare="true"/>

If you want to clean up the whole form, you can use such approach. This is your model into controller:

    $scope.registrationForm = {
    'firstName'     : '',
    'lastName'      : ''
};

Your HTML:

<form class="form-horizontal" name="registrForm" role="form">
   <input type="text" class="form-control"
                       name="firstName"
                       id="firstName"
                       ng-model="registrationForm.firstName"
                       placeholder="First name"
                       required> First name
   <input type="text" class="form-control"
                       name="lastName"
                       id="lastName"
                       ng-model="registrationForm.lastName"
                       placeholder="Last name"
                       required> Last name
</form>

Then, you should clone/save your clear state by:

$scope.originForm = angular.copy($scope.registrationForm);

Your reset function will be:

$scope.resetForm = function(){
    $scope.registrationForm = angular.copy($scope.originForm); // Assign clear state to modified form 
    $scope.registrForm.$setPristine(); // this line will update status of your form, but will not clean your data, where `registrForm` - name of form.
};

In such way you are able to clean up the whole your form

innerText is the current correct answer for this. The other answers are outdated and incorrect.

document.getElementById('ShowButton').innerText = 'Show filter';

innerHTML also works, and can be used to insert HTML.

Mine were located here on Ubuntu 18.04 when I installed JavaFX using apt install openjfx (as noted already by @jewelsea above)

I've had some problems either with selecting from INFORMATIONAL_SCHEME and OBJECT_ID. I don't know if it's an issue of ODBC driver or something.. Queries from SQL management studio, both, were okay.

Here is the solution:

SELECT COUNT(*) FROM <yourTableNameHere>

So, if the query fails, there is, probably, no such table in the database (or you don't have access permissions to it).

The check is done by comparing the value (integer in my case) returned by SQL executor which deals with ODBC driver..

if (sqlexec(conectionHandle, 'SELECT COUNT(*) FROM myTable') == -1) {
  // myTable doesn't exist..
}

You are wrong about LocalDateTime: it does not store any time-zone information and it has nanosecond precision. Quoting the Javadoc (emphasis mine):

A date-time without a time-zone in the ISO-8601 calendar system, such as 2007-12-03T10:15:30.

LocalDateTime is an immutable date-time object that represents a date-time, often viewed as year-month-day-hour-minute-second. Other date and time fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. Time is represented to nanosecond precision. For example, the value "2nd October 2007 at 13:45.30.123456789" can be stored in a LocalDateTime.

The difference between the two is that Instant represents an offset from the Epoch (01-01-1970) and, as such, represents a particular instant on the time-line. Two Instant objects created at the same moment in two different places of the Earth will have exactly the same value.

There is a code solution too. I saw it in a training video. You can add a line to tell IE that the local file is safe. I tested on IE8 and it works. That line is <!-- saved from url=(0014)about:internet -->

Try using private browsing in Safari or deleting your entire cache/cookies.

I've had some similar issues using chrome when the browser thought it had the website in its cache but actually had not.

The part of the http request that makes the server respond a 304 is the etag. Seems like Safari is sending the right etag without having the corresponding cache.

You could use only delegate which is best for callback functions:

public class ServerRequest
{
    public delegate void CallBackFunction(string input);

    public void DoRequest(string request, CallBackFunction callback)
    {
        // do stuff....
        callback(request);
    }
}

and consume this like below:

public class Class1
    {
        private void btn_click(object sender, EventArgs e)
        {
            ServerRequest sr = new ServerRequest();
            var callback = new ServerRequest.CallBackFunction(CallbackFunc);
            sr.DoRequest("myrequest",callback);
        }

        void CallbackFunc(string something)
        {

        }


    }

You could try specifying an HTTP response code using an optional parameter:

header('HTTP/1.0 404 Not Found', true, 404);

Rather than needing inline you could use Internal CSS

<a href="http://www.google.com" style="hover:text-decoration:none;">Google</a>

You could have:

<a href="http://www.google.com" id="gLink">Google</a>
<style>
  #gLink:hover {
     text-decoration: none;
  }
</style>

I did not find any of the answers satisfactory. All the mentioned libraries have some problem or the other like Cairo dropping support for python 3.6 (they dropped Python 2 support some 3 years ago!). Also, installing the mentioned libraries on the Mac was a pain.

Finally, I found the best solution was svglib + reportlab. Both installed without a hitch using pip and first call to convert from svg to png worked beautifully! Very happy with the solution.

Just 2 commands do the trick:

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPM
drawing = svg2rlg("my.svg")
renderPM.drawToFile(drawing, "my.png", fmt="PNG")

Are there any limitations with these I should be aware of?

Let take a string like :

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

Note: Underscore ( _ ) is not considered a special character in this case.

1. /\bX\b/g Should begin and end with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

2. /\bX/g Should begin with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

3. /X\b/g Should end with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

4. /\BX\B/g
   Should not begin and not end with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

5. /\BX/g Should not begin with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

6. /X\B/g Should not end with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

7. /\bX\B/g Should begin and not end with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

8. /\BX\b/g Should not begin and should end with a special character or white Space

XIX IXI XX X I II IIXX XXII I-I X-X -X X- X-I I-X -X- -I-X -X-I I-X- X-I- X_X _X-

If you insist on using ForEach-Object, then I would suggest adding a "break condition" like this:

$Break = $False;

1,2,3,4 | Where-Object { $Break -Eq $False } | ForEach-Object {

    $Break = $_ -Eq 3;

    Write-Host "Current number is $_";
}

The above code must output 1,2,3 and then skip (break before) 4. Expected output:

Current number is 1
Current number is 2
Current number is 3

If you don't want use timer and check innerHTML you can try this event

$('mydiv').bind('DOMSubtreeModified', function(){
  console.log('changed');
});

More details and browser support datas are Here.

Attention: in newer jQuery versions bind() is deprecated, so you should use on() instead:

$('body').on('DOMSubtreeModified', 'mydiv', function(){
  console.log('changed');
});

Android NDK official hello-libs CMake example

https://github.com/googlesamples/android-ndk/tree/840858984e1bb8a7fab37c1b7c571efbe7d6eb75/hello-libs

Just worked for me on Ubuntu 17.10 host, Android Studio 3, Android SDK 26, so I strongly recommend that you base your project on it.

The shared library is called libgperf, the key code parts are:

• hello-libs/app/src/main/cpp/CMakeLists.txt:

  // -L
  add_library(lib_gperf SHARED IMPORTED)
  set_target_properties(lib_gperf PROPERTIES IMPORTED_LOCATION
            ${distribution_DIR}/gperf/lib/${ANDROID_ABI}/libgperf.so)
  
  // -I
  target_include_directories(hello-libs PRIVATE
                             ${distribution_DIR}/gperf/include)
  // -lgperf
  target_link_libraries(hello-libs
                        lib_gperf)
  

• app/build.gradle:

  android {
      sourceSets {
          main {
              // let gradle pack the shared library into apk
              jniLibs.srcDirs = ['../distribution/gperf/lib']
  

  Then, if you look under /data/app on the device, libgperf.so will be there as well.

• on C++ code, use: #include <gperf.h>

• header location: hello-libs/distribution/gperf/include/gperf.h

• lib location: distribution/gperf/lib/arm64-v8a/libgperf.so

• If you only support some architectures, see: Gradle Build NDK target only ARM

The example git tracks the prebuilt shared libraries, but it also contains the build system to actually build them as well: https://github.com/googlesamples/android-ndk/tree/840858984e1bb8a7fab37c1b7c571efbe7d6eb75/hello-libs/gen-libs

Connect to the database with the "system" user, and execute the following command:

Pre Java 8:

Apache's commons lang is your friend here - it provides a join method very similar to the one you refer to in Ruby:

StringUtils.join(java.lang.Iterable,char)

Java 8:

Java 8 provides joining out of the box via StringJoiner and String.join(). The snippets below show how you can use them:

StringJoiner

StringJoiner joiner = new StringJoiner(",");
joiner.add("01").add("02").add("03");
String joinedString = joiner.toString(); // "01,02,03"

String.join(CharSequence delimiter, CharSequence... elements))

String joinedString = String.join(" - ", "04", "05", "06"); // "04 - 05 - 06"

String.join(CharSequence delimiter, Iterable<? extends CharSequence> elements)

List<String> strings = new LinkedList<>();
strings.add("Java");strings.add("is");
strings.add("cool");
String message = String.join(" ", strings);
//message returned is: "Java is cool"

I think the strictSSL: false should (should have worked, even in 2013) work. So in short are three possible ways:

1. (obvious) Get your CA to renew the certificate, and put it on your server!
2. Change the default settings of your request object:
   
   const myRequest = require('request').defaults({strictSSL: false})
   
   Many modules that use node-request internally also allow a request-object to be injected, so you can make them use your modified instance.
3. (not recommended) Override all certificate checks for all HTTP(S) agent connections by setting the environment variable NODE_TLS_REJECT_UNAUTHORIZED=0 for the Node.js process.

DOM is a logical model that can be implemented in any convenient manner.It is based on an object structure that closely resembles the structure of the documents it models.

For More Information on DOM : Click Here

Refer to http://api.jquery.com/on/

It says

In all browsers, the load, scroll, and error events (e.g., on an <img> element) do not bubble. In Internet Explorer 8 and lower, the paste and reset events do not bubble. Such events are not supported for use with delegation, but they can be used when the event handler is directly attached to the element generating the event.

If you want to do something when a new input box is added then you can simply write the code after appending it.

$('#add').click(function(){
        $('body').append(x);
        // Your code can be here
    });

And if you want the same code execute when the first input box within the document is loaded then you can write a function and call it in both places i.e. $('#add').click and document's ready event

Use this:

SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS RowNum FROM
    (SELECT DISTINCT id FROM table WHERE fid = 64) Base

and put the "output" of a query as the "input" of another.

Using CTE:

; WITH Base AS (
    SELECT DISTINCT id FROM table WHERE fid = 64
)

SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS RowNum FROM Base

The two queries should be equivalent.

Technically you could

SELECT DISTINCT id, ROW_NUMBER() OVER (PARTITION BY id ORDER BY id) AS RowNum 
    FROM table
    WHERE fid = 64

but if you increase the number of DISTINCT fields, you have to put all these fields in the PARTITION BY, so for example

SELECT DISTINCT id, description,
    ROW_NUMBER() OVER (PARTITION BY id, description ORDER BY id) AS RowNum 
    FROM table
    WHERE fid = 64

I even hope you comprehend that you are going against standard naming conventions here, id should probably be a primary key, so unique by definition, so a DISTINCT would be useless on it, unless you coupled the query with some JOINs/UNION ALL...

The action occurs when you attempt to call an object which is not a function, as with (). For instance, this will produce the error:

>>> a = 5
>>> a()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

Class instances can also be called if they define a method __call__

One common mistake that causes this error is trying to look up a list or dictionary element, but using parentheses instead of square brackets, i.e. (0) instead of [0]

You can solve the problem with the global solution, but firstly I want to describe the solution for each project individually, cause of trustfully compatibility with most of Git clients and other implemented Git environments:

• Individual Solution

Go to the following location:

Local/repo/location/.git/

open "config" file there, and set your parameters like the example (add to the end of the file):

[user]
    name = YOUR-NAME
    email = YOUR-EMAIL-ADDRESS

• Global Solution

Open a command line and type:

git config --global user.email "[email protected]"
git config --global user.name "YOUR NAME"

You can build DFA using simple modular arithmetics. We can interpret w which is a string of k-ary numbers using a following rule

V[0] = 0
V[i] = (S[i-1] * k) + to_number(str[i])

V[|w|] is a number that w is representing. If modify this rule to find w mod N, the rule becomes this.

V[0] = 0
V[i] = ((S[i-1] * k) + to_number(str[i])) mod N

and each V[i] is one of a number from 0 to N-1, which corresponds to each state in DFA. We can use this as the state transition.

See an example.

k = 2, N = 5

| V | (V*2 + 0) mod 5     | (V*2 + 1) mod 5     |
+---+---------------------+---------------------+
| 0 | (0*2 + 0) mod 5 = 0 | (0*2 + 1) mod 5 = 1 |
| 1 | (1*2 + 0) mod 5 = 2 | (1*2 + 1) mod 5 = 3 |
| 2 | (2*2 + 0) mod 5 = 4 | (2*2 + 1) mod 5 = 0 |
| 3 | (3*2 + 0) mod 5 = 1 | (3*2 + 1) mod 5 = 2 |
| 4 | (4*2 + 0) mod 5 = 3 | (4*2 + 1) mod 5 = 4 |

k = 3, N = 5

| V | 0 | 1 | 2 |
+---+---+---+---+
| 0 | 0 | 1 | 2 |
| 1 | 3 | 4 | 0 |
| 2 | 1 | 2 | 3 |
| 3 | 4 | 0 | 1 |
| 4 | 2 | 3 | 4 |

Now you can see a very simple pattern. You can actually build a DFA transition just write repeating numbers from left to right, from top to bottom, from 0 to N-1.

It's preferable to use context managers to close the files automatically

with open("new.txt", "r"), open('xyz.txt', 'w') as textfile, myfile:
    for line in textfile:
        var1, var2 = line.split(",");
        myfile.writelines(var1)

Useful for some columns that had multiple default constraints or check constraints created:

Modified https://stackoverflow.com/a/16359095/206730 script

Note: this script is for sys.check_constraints

declare @table_name nvarchar(128)
declare @column_name nvarchar(128)
declare @constraint_name nvarchar(128)
declare @constraint_definition nvarchar(512)

declare @df_name nvarchar(128)
declare @cmd nvarchar(128) 

PRINT 'DROP CONSTRAINT [Roles2016.UsersCRM].Estado'

declare constraints cursor for 
 select t.name TableName, c.name ColumnName, d.name ConstraintName, d.definition ConstraintDefinition
 from sys.tables t   
 join sys.check_constraints d  on d.parent_object_id = t.object_id  
 join sys.columns c  on c.object_id = t.object_id      
 and c.column_id = d.parent_column_id
 where t.name = N'Roles2016.UsersCRM' and c.name = N'Estado'

open constraints
fetch next from constraints into @table_name , @column_name, @constraint_name, @constraint_definition
while @@fetch_status = 0
BEGIN
    print 'CONSTRAINT: ' + @constraint_name
    select @cmd = 'ALTER TABLE [' + @table_name +  '] DROP CONSTRAINT [' +  @constraint_name + ']'
    print @cmd
    EXEC sp_executeSQL @cmd;

  fetch next from constraints into @table_name , @column_name, @constraint_name, @constraint_definition
END

close constraints 
deallocate constraints

Use MySQL's STR_TO_DATE() function to parse the string that you're attempting to insert:

INSERT INTO tblInquiry (fldInquiryReceivedDateTime) VALUES
  (STR_TO_DATE('5/15/2012 8:06:26 AM', '%c/%e/%Y %r'))

In the toolbar in the bottom right corner you will see a item that looks like the following: After clicking on it you will get the option to indent using either spaces or tabs. After selecting your indent type you will then have the option to change how big an indent is. In the case of the example above, indentation is set to 4 space characters per indent. If tab is selected as your indentation character then you will see Tab Size instead of Spaces

If you want to have this apply to all files and not on an idividual file basis, override the Editor: Tab Size and Editor: Insert Spaces settings in either User Settings or Workspace Settings depending on your needs

Edit 1

To get to your user or workspace settings go to Preferences -> Settings. Verify that you are on the User or Workspace tab depending on your needs and use the search bar to locate the settings. You may also want to disable Editor: Detect Indentation as this setting will override what you set for Editor: Insert Spaces and Editor: Tab Size when it is enabled

simple query would be, just set a variable to some number you want. then update the column you need by incrementing 1 from that number. for all the rows it'll update each row id by incrementing 1

SET @a  = 50000835 ;  
UPDATE `civicrm_contact` SET external_identifier = @a:=@a+1 
WHERE external_identifier IS NULL;

This works for me:

scrollview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        scrollview.post(new Runnable() {
            public void run() {
                scrollview.fullScroll(View.FOCUS_DOWN);
            }
        });
    }
});

I just want to post this as an actual post as it is easy to miss this in the comments.

The correct and best answer for this question was given by @Jake Berger, Thank you very much dude, everyone need this and everyone misses this in the comments. So for everyone struggling with this here is the correct answer, just use the output of this command to know if you need to do a git pull. if the output is 0 then obviously there is nothing to update.

@stackoverflow, give this guy a bells. Thanks @ Jake Berger

git rev-list HEAD...origin/master --count will give you the total number of "different" commits between the two. – Jake Berger Feb 5 '13 at 19:23

First set a custom attribute into your option for example nameid (you can set non-standardized attribute of an HTML element, it's allowed):

'<option nameid= "' + n.id + "' value="' + i + '">' + n.names + '</option>'

then you can easily get attribute value using jquery .attr() :

$('option:selected').attr("nameid")

For Example:

<select id="jobSel" class="longcombo" onchange="GetNameId">
    <option nameid="32" value="1">test1</option>
    <option nameid="67" value="1">test2</option>
    <option nameid="45" value="1">test3</option>    
    </select>    

Jquery:

function GetNameId(){
   alert($('#jobSel option:selected').attr("nameid"));
}

using from ListSelectionModel:

ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
  public void valueChanged(ListSelectionEvent e) {
    String selectedData = null;

    int[] selectedRow = table.getSelectedRows();
    int[] selectedColumns = table.getSelectedColumns();

    for (int i = 0; i < selectedRow.length; i++) {
      for (int j = 0; j < selectedColumns.length; j++) {
        selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
      }
    }
    System.out.println("Selected: " + selectedData);
  }

});

see here.

If you have Excel 2007 or later use COUNTIFS with an "S" on the end, i.e.

=COUNTIFS(B2:B292,">10",B2:B292,"<10000")

You may need to change commas , to semi-colons ;

In earlier versions of excel use SUMPRODUCT like this

=SUMPRODUCT((B2:B292>10)*(B2:B292<10000))

Note: if you want to include exactly 10 change > to >= - similarly with 10000, change < to <=

This may be overkill, but the Celery distributed task queue has good support for timeouts.

In particular, you can define a soft time limit that just raises an exception in your process (so you can clean up) and/or a hard time limit that terminates the task when the time limit has been exceeded.

Under the covers, this uses the same signals approach as referenced in your "before" post, but in a more usable and manageable way. And if the list of web sites you are monitoring is long, you might benefit from its primary feature -- all kinds of ways to manage the execution of a large number of tasks.

• suppose you have an array like

   const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9]
    
    
    arr.map((myArr, index) => {
      console.log(`your index is -> ${index} AND value is ${myArr}`);
    })

> output will be
 index is -> 0 AND value is 1
 index is -> 1 AND value is 2
 index is -> 2 AND value is 3
 index is -> 3 AND value is 4
 index is -> 4 AND value is 5
 index is -> 5 AND value is 6
 index is -> 6 AND value is 7
 index is -> 7 AND value is 8
 index is -> 8 AND value is 9

Go to the SQL Server Management Studio, navigate to Security, go to Logins and right click it. A Menu will come up with a button saying "New Login". There you will be able to add users and/or groups from Active Directory to your SQL Server "permissions". Hope this helps

The "nav nav-list" class of Twiter Bootstrap 2.0 is handy for building a side bar.

You can see a lot of documentation at http://www.w3resource.com/twitter-bootstrap/nav-tabs-and-pills-tutorial.php

Make a truth table and use SUMPRODUCT to get the values. Copy this into cell B1 on Sheet2 and copy down as far as you need:
=SUMPRODUCT(--($A1 = Sheet1!$A:$A), Sheet1!$B:$B)
the part that creates the truth table is:
--($A1 = Sheet1!$A:$A)
This returns an array of 0's and 1's. 1 when the values match and a 0 when they don't. Then the comma after that will basically do what I call "funny" matrix multiplication and will return the result. I may have misunderstood your question though, are there duplicate values in Column A of Sheet1?

use with quotes

ex: adb shell "svc wifi enable"

this will work :)

The first one creates a single lambda function and calls it ten times.

The second one doesn't call the function. It creates 10 different lambda functions. It puts all of those in a list. To make it equivalent to the first you need:

[(lambda x: x*x)(x) for x in range(10)]

Or better yet:

[x*x for x in range(10)]

Based on bithavoc, it lists the last tag until HEAD. But I hope to list the logs between 2 tags.

// 2 or 3 dots between `YOUR_LAST_VERSION_TAG` and `HEAD`
git log YOUR_LAST_VERSION_TAG..HEAD --no-merges --format=%B

List logs between 2 tags.

// 2 or 3 dots between 2 tags
git log FROM_TAG...TO_TAG

For example, it will list logs from v1.0.0 to v1.0.1.

git log v1.0.0...v1.0.1 --oneline --decorate

The following code returns the wanted "folder" as Path regardless of if it is inside a jar or not.

  private Path getFolderPath() throws URISyntaxException, IOException {
    URI uri = getClass().getClassLoader().getResource("folder").toURI();
    if ("jar".equals(uri.getScheme())) {
      FileSystem fileSystem = FileSystems.newFileSystem(uri, Collections.emptyMap(), null);
      return fileSystem.getPath("path/to/folder/inside/jar");
    } else {
      return Paths.get(uri);
    }
  }

Requires java 7+.

I think it is confusing to think of it in terms of negative numbers. Since it is a logarithm think of the negative values the same way you think of powers of ten. 10^3 = 1000 while 10^-3 = 0.001.

With this in mind and using the formulas from S Lists's answer (and assuming our base power is 1mW in all these cases) we can build a little table:

|--------|-------------------|
| P(dBm) |        P(mW)      |
|--------|-------------------|
|    50  |  100000           |    
|    40  |   10000           |    strong transmitter
|    30  |    1000           |             ^  
|    20  |     100           |             |
|    10  |      10           |             |
|     0  |       1           |
|   -10  |       0.1         |
|   -20  |       0.01        |
|   -30  |       0.001       |
|   -40  |       0.0001      |
|   -50  |       0.00001     |             |
|   -60  |       0.000001    |             |
|   -70  |       0.0000001   |             v
|   -80  |       0.00000001  |    sensitive receiver
|   -90  |       0.000000001 |
|--------|-------------------|

When I think of it like this I find that it's easier to see that the more negative the dBm value then the farther to the right of the decimal the actual power value is.

When it comes to mobile networks, it not so much that they aren't powerful enough, rather it is that they are more sensitive. When you see receivers specs with dBm far into the negative values, then what you are seeing is more sensitive equipment.

Normally you would want your transmitter to be powerful (further in to the positives) and your receiver to be sensitive (further in to the negatives).

If you're running on an AWS instance that is running Amazon Linux OS, the magic command to fix this for me was

sudo yum install tkinter

I think the original question can easily be answered with something being overlooked so far: a simple string split. The time being returned is a text string, just split it on the ":" delimiter and reassemble the string the way you want. No plug ins, no complicated scripting. and here ya go:

var myVar=setInterval(function(){myTimer()},1000);

function myTimer() {
    var d = new Date();
    currentNow = d.toLocaleTimeString();
    nowArray = currentNow.split(':');
    filteredNow = nowArray[0]+':'+nowArray[1];
    document.getElementById("demo").innerHTML = filteredNow;
}

window.onload = codeAddress; should work - here's a demo, and the full code:

<!DOCTYPE html>_x000D_

a div usually needs at least a non-breaking space (&nbsp;) in order to have a width.

New Item>Project Name = abc > Instead of Freestyle job, select Copy from job name of already existing jobs

If you are inside the folder that you want to copy out of the directory then use ../.

Also be sure your home directory is not writeable by others:

chmod g-w,o-w /home/USERNAME

This answer is stolen from here.

When you use float without width, there remains some space in that row. To block this space you can use clear:both; in next element.

AlertDialog.setView(View view) does add the given view to the R.id.custom FrameLayout. The following is a snippet of Android source code from AlertController.setupView() which finally handles this (mView is the view given to AlertDialog.setView method).

...
FrameLayout custom = (FrameLayout) mWindow.findViewById(R.id.**custom**);
custom.addView(**mView**, new LayoutParams(FILL_PARENT, FILL_PARENT));
...

if you are ubuntu user than try this:

sudo apt-get remove jenkins
sudo apt-get remove --auto-remove jenkins

'apt-get remove' command is use to remove package.

namespace std
{
  // define std::byte
  enum class byte : unsigned char {};

};

This if your C++ version does not have std::byte will define a byte type in namespace std. Normally you don't want to add things to std, but in this case it is a standard thing that is missing.

std::byte from the STL does much more operations.

just type cordova platform ls

This will list all the platforms installed along with its version and available for installation plus :)

The permanent space is where the classes, methods, internalized strings, and similar objects used by the VM are stored and never deallocated (hence the name).

This Oracle article succinctly presents the working and parameterization of the HotSpot GC and advises you to augment this space if you load many classes (this is typically the case for application servers and some IDE like Eclipse) :

The permanent generation does not have a noticeable impact on garbage collector performance for most applications. However, some applications dynamically generate and load many classes; for example, some implementations of JavaServer Pages (JSP) pages. These applications may need a larger permanent generation to hold the additional classes. If so, the maximum permanent generation size can be increased with the command-line option -XX:MaxPermSize=.

Note that this other Oracle documentation lists the other HotSpot arguments.

Update : Starting with Java 8, both the permgen space and this setting are gone. The memory model used for loaded classes and methods is different and isn't limited (with default settings). You should not see this error any more.

While the answer above is correct I would not recommend you to change the name in order to rely on it in the code.

Names are tricky. They can change. You should use the ShapeId and SlideId.

Especially beware to change the name of a shape programmatically since PowerPoint relies on the name and it might hinder its regular operation.

What about the following for doing a range incremented by days:

for d in map( lambda x: startDate+datetime.timedelta(days=x), xrange( (stopDate-startDate).days ) ):
  # Do stuff here

• startDate and stopDate are datetime.date objects

For a generic version:

for d in map( lambda x: startTime+x*stepTime, xrange( (stopTime-startTime).total_seconds() / stepTime.total_seconds() ) ):
  # Do stuff here

• startTime and stopTime are datetime.date or datetime.datetime object (both should be the same type)
• stepTime is a timedelta object

Note that .total_seconds() is only supported after python 2.7 If you are stuck with an earlier version you can write your own function:

def total_seconds( td ):
  return float(td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 10**6

This works for me using JsonConvert

var result = JsonConvert.DeserializeObject<Class>(responseString);

Sybase IQ:

describe table_name;

Another way to move all files in a directory to a sub directory (keeps git history):

$ for file in $(ls | grep -v 'subDir'); do git mv $file subDir; done;

Among several options for shading and tinting:

• For shades, multiply each component by 1/4, 1/2, 3/4, etc., of its previous value. The smaller the factor, the darker the shade.

• For tints, calculate (255 - previous value), multiply that by 1/4, 1/2, 3/4, etc. (the greater the factor, the lighter the tint), and add that to the previous value (assuming each.component is a 8-bit integer).

Note that color manipulations (such as tints and other shading) should be done in linear RGB. However, RGB colors specified in documents or encoded in images and video are not likely to be in linear RGB, in which case a so-called inverse transfer function needs to be applied to each of the RGB color's components. This function varies with the RGB color space. For example, in the sRGB color space (which can be assumed if the RGB color space is unknown), this function is roughly equivalent to raising each sRGB color component (ranging from 0 through 1) to a power of 2.2. (Note that "linear RGB" is not an RGB color space.)

WHERE p.[Type] = isnull(@SearchType, p.[Type])

Try this

function sendRequest(method, url, payload, done){

        var datatype = (method === "JSONP")? "jsonp" : "json";
        $http({
                method: method,
                url: url,
                dataType: datatype,
                data: payload || {},
                cache: true,
                timeout: 1000 * 60 * 10
        }).then(
            function(res){
                done(null, res.data); // server response
            },
            function(res){
                responseHandler(res, done);
            }
        );

    }
    function responseHandler(res, done){
        switch(res.status){
            default: done(res.status + ": " + res.statusText);
        }
    }

the correct answer is @chepner's

EXT=java
for i in *.${EXT}; do
    ...
done

however, here's a small trick to check whether a filename has a given extensions:

EXT=java
for i in *; do
    if [ "${i}" != "${i%.${EXT}}" ];then
        echo "I do something with the file $i"
    fi
done

Seeing from your G++ version, you need to update it badly. C++11 has only been available since G++ 4.3. The most recent version is 4.7.

In versions pre-G++ 4.7, you'll have to use -std=c++0x, for more recent versions you can use -std=c++11.

AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.

As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.

So AArch64 and ARM64 refer to the same thing.

If you don't want to implement your connector customizer, you can build and import the library (https://github.com/ycavatars/spring-boot-https-kit) which provides predefined connector customizer. According to the README, you only have to create your keystore, configure connector.https.*, import the library and add @ComponentScan("org.ycavatars.sboot.kit"). Then you'll have HTTPS connection.

Pure4J supports what you are after, in two ways.

First, it provides an @ImmutableValue annotation, so that you can annotate a class to say that it is immutable. There is a maven plugin to allow you to check that your code actually is immutable (use of final etc.).

Second, it provides the persistent collections from Clojure, (with added generics) and ensures that elements added to the collections are immutable. Performance of these is apparently pretty good. Collections are all immutable, but implement java collections interfaces (and generics) for inspection. Mutation returns new collections.

request.getRequestDispatcher(“url”) means the dispatch is relative to the current HTTP request.Means this is for chaining two servlets with in the same web application Example

RequestDispatcher reqDispObj = request.getRequestDispatcher("/home.jsp");

getServletContext().getRequestDispatcher(“url”) means the dispatch is relative to the root of the ServletContext.Means this is for chaining two web applications with in the same server/two different servers

Example

RequestDispatcher reqDispObj = getServletContext().getRequestDispatcher("/ContextRoot/home.jsp");

In addition, say two object array with different key value

// Array Object 1
const arrayObjOne = [
    { userId: "1", display: "Jamsheer" },
    { userId: "2", display: "Muhammed" },
    { userId: "3", display: "Ravi" },
    { userId: "4", display: "Ajmal" },
    { userId: "5", display: "Ryan" }
]

// Array Object 2
const arrayObjTwo =[
    { empId: "1", display: "Jamsheer", designation:"Jr. Officer" },
    { empId: "2", display: "Muhammed", designation:"Jr. Officer" },
    { empId: "3", display: "Ravi", designation:"Sr. Officer" },
    { empId: "4", display: "Ajmal", designation:"Ast. Manager" },
]

You can use filter in es5 or native js to substract two array object.

//Find data that are in arrayObjOne but not in arrayObjTwo
var uniqueResultArrayObjOne = arrayObjOne.filter(function(objOne) {
    return !arrayObjTwo.some(function(objTwo) {
        return objOne.userId == objTwo.empId;
    });
});

In ES6 you can use Arrow function with Object destructuring of ES6.

const ResultArrayObjOne = arrayObjOne.filter(({ userId: userId }) => !arrayObjTwo.some(({ empId: empId }) => empId === userId));

console.log(ResultArrayObjOne);

You can call AttachConsole using pinvoke to get a console window attached to a WinForms project: http://www.csharp411.com/console-output-from-winforms-application/

You may also want to consider Log4net ( http://logging.apache.org/log4net/index.html ) for configuring log output in different configurations.

This is just an add-on to the solution in case you want to compute not only unique values but other aggregate functions:

df.groupby(['group']).agg(['min','max','count','nunique'])

Hope you find it useful

The :first-child selector is intended, like the name says, to select the first child of a parent tag. The children have to be embedded in the same parent tag. Your exact example will work (Just tried it here):

<body>
    <p class="red">first</p>
    <div class="red">second</div>
</body>

Maybe you have nested your tags in different parent tags? Are your tags of class red really the first tags under the parent?

Notice also that this doesnt only apply to the first such tag in the whole document, but everytime a new parent is wrapped around it, like:

<div>
    <p class="red">first</p>
    <div class="red">second</div>
</div>
<div>
    <p class="red">third</p>
    <div class="red">fourth</div>
</div>

first and third will be red then.

Update:

I dont know why martyn deleted his answer, but he had the solution, the :nth-of-type selector:

.red:nth-of-type(1)_x000D_
{_x000D_
    border:5px solid red;_x000D_
} 

<div class="home">_x000D_
    <span>blah</span>_x000D_
    <p class="red">first</p>_x000D_
    <p class="red">second</p>_x000D_
    <p class="red">third</p>_x000D_
    <p class="red">fourth</p>_x000D_
</div>

Credits to Martyn. More infos for example here. Be aware that this is a CSS 3 selector, therefore not all browsers will recognize it (e.g. IE8 or older).

Creating (and destroying) a bunch of String instances is not a good way if performance is an issue.

Please ignore those verbose (duplicate) arguments checking statements (ifs). That's for (another) educational purposes.

In validation, of this question, it really depends on what !DOCTYPE you are trying to get verification through.

My personal favorite is 4.01 Trans where I just use the <br/> and it clears the warnings and errors that may have popped up during validation

Strict is a much more complicated beast, It HATES "SHORTTAGS" and quite literally only wants the <br></br>

In HTML5 or the "LAX" of the code world, there really isn't a right answer because it detects every example you put up there as correct......

In the end, I think all that matters is what validation YOU PREFER or the person that you are working for prefers... with the lackadaisical movement in code strictness in html5 we are seeing some VERY LAZY CODERS

const express = require('express');                                                                                                                           
const morgan = require('morgan')
const PORT = 3000;

morgan.token('port', (req) => { 
    return req.app.locals.port; 
});

const app = express();
app.locals.port = PORT;
app.use(morgan(':method :url :port'))
app.get('/app', function(req, res) {
    res.send("Hello world from server");
});

app1.listen(PORT);

// If you just want to see the year difference then use this function.
// Using the logic I've created you may also create month and day difference
// which I did not provide here so you may have the efforts to use your brain.
// :)
$date1='2009-01-01';
$date2='2010-01-01';
echo getYearDifference ($date1,$date2);
function getYearDifference($date1=strtotime($date1),$date2=strtotime($date2)){
    $year = 0;
    while($date2 > $date1 = strtotime('+1 year', $date1)){
        ++$year;
    }
    return $year;
}

Input masks can be implemented using a combination of the keyup event, and the HTMLInputElement value, selectionStart, and selectionEnd properties. Here's a very simple implementation which does some of what you want. It's certainly not perfect, but works well enough to demonstrate the principle:

Array.prototype.forEach.call(document.body.querySelectorAll("*[data-mask]"), applyDataMask);_x000D_
_x000D_
function applyDataMask(field) {_x000D_
    var mask = field.dataset.mask.split('');_x000D_
    _x000D_
    // For now, this just strips everything that's not a number_x000D_
    function stripMask(maskedData) {_x000D_
        function isDigit(char) {_x000D_
            return /\d/.test(char);_x000D_
        }_x000D_
        return maskedData.split('').filter(isDigit);_x000D_
    }_x000D_
    _x000D_
    // Replace `_` characters with characters from `data`_x000D_
    function applyMask(data) {_x000D_
        return mask.map(function(char) {_x000D_
            if (char != '_') return char;_x000D_
            if (data.length == 0) return char;_x000D_
            return data.shift();_x000D_
        }).join('')_x000D_

There are also a number of libraries out there which perform this function. Some examples include:

• jquery.inputmask
• MASKED INPUT PLUGIN
• Politespace (presents an alternative to input masks)

One of the weird behaviour and spec in Javascript is the typeof Array is Object.

You can check if the variable is an array in couple of ways:

var isArr = data instanceof Array;
var isArr = Array.isArray(data);

But the most reliable way is:

isArr = Object.prototype.toString.call(data) == '[object Array]';

Since you tagged your question with jQuery, you can use jQuery isArray function:

var isArr = $.isArray(data);

Just in case if you are using .BAT file as Windows Service, I would suggest to uninstall the Windows service and reinstall it again after changing the %JAVA_HOME% to point to the right Java version..

Try this.

<script>
function checkIframeLoaded() {
    // Get a handle to the iframe element
    var iframe = document.getElementById('i_frame');
    var iframeDoc = iframe.contentDocument || iframe.contentWindow.document;

    // Check if loading is complete
    if (  iframeDoc.readyState  == 'complete' ) {
        //iframe.contentWindow.alert("Hello");
        iframe.contentWindow.onload = function(){
            alert("I am loaded");
        };
        // The loading is complete, call the function we want executed once the iframe is loaded
        afterLoading();
        return;
    } 

    // If we are here, it is not loaded. Set things up so we check   the status again in 100 milliseconds
    window.setTimeout(checkIframeLoaded, 100);
}

function afterLoading(){
    alert("I am here");
}
</script>

<body onload="checkIframeLoaded();">

On Windows7 the .gemrc file is not present, you can let Ruby create one like this (it's not easy to do this in explorer).

gem sources --add http://rubygems.org

You will have to confirm (it's unsafe). Now the file is created in your userprofile folder (c:\users\)

You can edit the textfile to remove the source you added or you can remove it with

gem sources --remove http://rubygems.org

Alternatively, you could try using pydot for producing the png file from dot:

...
tree.export_graphviz(dtreg, out_file='tree.dot') #produces dot file

import pydot
dotfile = StringIO()
tree.export_graphviz(dtreg, out_file=dotfile)
pydot.graph_from_dot_data(dotfile.getvalue()).write_png("dtree2.png")
...

Unlike IDs, tags are not used to identify views. Tags are essentially an extra piece of information that can be associated with a view. They are most often used as a convenience to store data related to views in the views themselves rather than by putting them in a separate structure.

With bash version >= 4.2:

printf "%(%H:%M)T\n"

or

printf -v foo "%(%H:%M)T\n"
echo "$foo"

See: man bash

SQLite has a printf function which does exactly that:

SELECT printf('%s-%.2d-%.4d', col1, col2, col3) FROM mytable

Assuming that you have access to Prototype, this could work. I wrote this code for myself just a few minutes ago; I only needed a single key at a time, so this isn't time efficient for big lists of key:value pairs or for spitting out multiple key names.

function key(int) {
    var j = -1;
    for(var i in this) {
        j++;
        if(j==int) {
            return i;
        } else {
            continue;
        }
    }
}
Object.prototype.key = key;

This is numbered to work the same way that arrays do, to save headaches. In the case of your code:

buttons.key(0) // Should result in "button1"

Set is just an interface. In order to retain order, you have to use a specific implementation of that interface and the sub-interface SortedSet, for example TreeSet or LinkedHashSet. You can wrap your Set this way:

Set myOrderedSet = new LinkedHashSet(mySet);

layout.xml

<Button
    android:id="@+id/buttonBack"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:onClick="finishActivity"
    android:text="Back" />

Activity.java

public void finishActivity(View v){
    finish();
}

Instead of having static methods and passing around a pointer to the class instance, you could use functionality in the new C++11 standard: std::function and std::bind:

#include <functional>
class EventHandler
{
    public:
        void addHandler(std::function<void(int)> callback)
        {
            cout << "Handler added..." << endl;
            // Let's pretend an event just occured
            callback(1);
        }
};

The addHandler method now accepts a std::function argument, and this "function object" have no return value and takes an integer as argument.

To bind it to a specific function, you use std::bind:

class MyClass
{
    public:
        MyClass();

        // Note: No longer marked `static`, and only takes the actual argument
        void Callback(int x);
    private:
        int private_x;
};

MyClass::MyClass()
{
    using namespace std::placeholders; // for `_1`

    private_x = 5;
    handler->addHandler(std::bind(&MyClass::Callback, this, _1));
}

void MyClass::Callback(int x)
{
    // No longer needs an explicit `instance` argument,
    // as `this` is set up properly
    cout << x + private_x << endl;
}

You need to use std::bind when adding the handler, as you explicitly needs to specify the otherwise implicit this pointer as an argument. If you have a free-standing function, you don't have to use std::bind:

void freeStandingCallback(int x)
{
    // ...
}

int main()
{
    // ...
    handler->addHandler(freeStandingCallback);
}

Having the event handler use std::function objects, also makes it possible to use the new C++11 lambda functions:

handler->addHandler([](int x) { std::cout << "x is " << x << '\n'; });

string s2 = s1.Replace(",", ",\n");

You can use (mouseover) and (mouseout) events.

component.ts

changeText:boolean=true;

component.html

<div (mouseover)="changeText=true" (mouseout)="changeText=false">
  <span [hidden]="changeText">Hide</span>
  <span [hidden]="!changeText">Show</span>
</div>

I also faced the same issue and got a solution very similar:

1. Changing the classpath to classpath 'com.android.tools.build:gradle:2.3.2'

   Image after adding the classpath

2. A new message indicating to Update Build Tool version, so just click that message to update. Update

Serialization is the process of turning a Java object into byte array and then back into object again with its preserved state. Useful for various things like sending objects over network or caching things to disk.

Read more from this short article which explains programming part of the process quite well and then move over to to Serializable javadoc. You may also be interested in reading this related question.

there are packages that can simulate interfaces .

you can use es6-interface

All answers are quite old. Since the beginning of 2013 Mongoose started to support promises gradually for all queries, so that would be the recommended way of structuring several async calls in the required order going forward I guess.

Maintain an array which stores data in the cellforindexPath method itself :-

[arryname objectAtIndex:indexPath.row];

Using same code in the didselectaAtIndexPath method too.. Good luck :)

For everyone using .NET Core CLI on MinGW MSYS. After installing using

dotnet tool install --global dotnet-ef

add this line to to bashrc file c:\msys64\home\username\ .bashrc (location depend on your setup)

export PATH=$PATH:/c/Users/username/.dotnet/tools

updating maven worked for me

select project then press ALT+F5 then select project click ok

The solution I present is safe, simple and compatible with Internet Explorer, FireFox and Chrome.

This approach is new and complete. I not found nothing equal to that solution on the internet. Is simple, cross-browser (Internet Explorer, Chrome and Firefox), preserves the layout, use the select itself and is easy to use.

Note: JQuery is required.

I've meet the probleme recently. The trouble is coming when the filename lenght is greather than 20 characters. So the bypass is to change your filename length, but the trick is also a good one.

$.ajaxSetup({async: false}); // passage en mode synchrone
$.ajax({
   url: pathpays,
   success: function(data) {
      //debug(data);
      $(data).find("a:contains(.png),a:contains(.jpg)").each(function() {
         var image = $(this).attr("href");
         // will loop through
         debug("Found a file: " + image);
         text +=  '<img class="arrondie" src="' + pathpays + image + '" />';
      });
      text = text + '</div>';
      //debug(text);
   }
});

After more investigation the trouble is coming from ajax request: Put an eye to the html code returned by ajax:

<a href="Paris-Palais-de-la-cite%20-%20Copie.jpg">Paris-Palais-de-la-c..&gt;</a>
</td>
<td align="right">2015-09-05 09:50 </td>
<td align="right">4.3K</td>
<td>&nbsp;</td>
</tr>

As you can see the filename is splitted after the character 20, so the $(data).find("a:contains(.png)) is not able to find the correct extention.

But if you check the value of the href parameter it contents the fullname of the file.

I dont know if I can to ask to ajax to return the full filename in the text area?

Hope to be clear

I've found the right test to gather all files:

$(data).find("[href$='.jpg'],[href$='.png']").each(function() {  
var image = $(this).attr("href");

Besides not being a lazy evaluator by evaluating both operands, I think the main characteristics of bitwise operators compare each bytes of operands like in the following example:

int a = 4;
int b = 7;
System.out.println(a & b); // prints 4
//meaning in an 32 bit system
// 00000000 00000000 00000000 00000100
// 00000000 00000000 00000000 00000111
// ===================================
// 00000000 00000000 00000000 00000100

When I create a table using SSMS 2008, I see 3 panes:

• The column designer
• Column properties
• The table properties

In the table properties pane, there is a field: Schema which allows you to select the schema.

Since iOS 11, you can use the native framework called PDFKit for displaying and manipulating PDFs.

After importing PDFKit, you should initialize a PDFView with a local or a remote URL and display it in your view.

if let url = Bundle.main.url(forResource: "example", withExtension: "pdf") {
    let pdfView = PDFView(frame: view.frame)
    pdfView.document = PDFDocument(url: url)
    view.addSubview(pdfView)
}

Read more about PDFKit in the Apple Developer documentation.

Mitch is right. It depends on resources (memory).

Although Raymond's article is dedicated to Windows threads, not to C# threads, the logic applies the same (C# threads are mapped to Windows threads).

However, as we are in C#, if we want to be completely precise, we need to distinguish between "started" and "non started" threads. Only started threads actually reserve stack space (as we could expect). Non started threads only allocate the information required by a thread object (you can use reflector if interested in the actual members).

You can actually test it for yourself, compare:

    static void DummyCall()
    {
        Thread.Sleep(1000000000);
    }

    static void Main(string[] args)
    {
        int count = 0;
        var threadList = new List<Thread>();
        try
        {
            while (true)
            {
                Thread newThread = new Thread(new ThreadStart(DummyCall), 1024);
                newThread.Start();
                threadList.Add(newThread);
                count++;
            }
        }
        catch (Exception ex)
        {
        }
    }

with:

   static void DummyCall()
    {
        Thread.Sleep(1000000000);
    }

    static void Main(string[] args)
    {
        int count = 0;
        var threadList = new List<Thread>();
        try
        {
            while (true)
            {
                Thread newThread = new Thread(new ThreadStart(DummyCall), 1024);
                threadList.Add(newThread);
                count++;
            }
        }
        catch (Exception ex)
        {
        }
    }

Put a breakpoint in the exception (out of memory, of course) in VS to see the value of counter. There is a very significant difference, of course.

This also works:

Model:

public class ViewModel
{         
    public HttpPostedFileBase File{ get; set; }
}

View:

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new 
                                       { enctype = "multipart/form-data" }))
{
    @Html.TextBoxFor(m => m.File, new { type = "file" })       
}

Controller action:

[HttpPost]
public ActionResult Action(ViewModel model)
{
    if (ModelState.IsValid)
    {
        var postedFile = Request.Files["File"];

       // now you can get and validate the file type:
        var isFileSupported= IsFileSupported(postedFile);

    }
}

public bool IsFileSupported(HttpPostedFileBase file)
            {
                var isSupported = false;

                switch (file.ContentType)
                {

                    case ("image/gif"):
                        isSupported = true;
                        break;

                    case ("image/jpeg"):
                        isSupported = true;
                        break;

                    case ("image/png"):
                        isSupported = true;
                        break;


                    case ("audio/mp3"):  
                        isSupported = true;
                        break;

                    case ("audio/wav"):  
                        isSupported = true;
                        break;                                 
                }

                return isSupported;
            }

List of contentTypes

''.join('%02x'%i for i in input)

Not all view are listed directly in every perspective ... choose:

Window->Show View->Other...->Java->Package Explorer

A simple solution I frequently use:

arr = ['remove me',3,4,2,45]

arr[1..-1]

=> [3,4,2,45]

you can also just run it with a shell, for example:

bash example.txt

sh example.txt

Here's generally how to select multiple columns from a subquery:

SELECT
     A.SalesOrderID,
     A.OrderDate,
     SQ.Max_Foo,
     SQ.Max_Foo2
FROM
     A
LEFT OUTER JOIN
     (
     SELECT
          B.SalesOrderID,
          MAX(B.Foo) AS Max_Foo,
          MAX(B.Foo2) AS Max_Foo2
     FROM
          B
     GROUP BY
          B.SalesOrderID
     ) AS SQ ON SQ.SalesOrderID = A.SalesOrderID

If what you're ultimately trying to do is get the values from the row with the highest value for Foo (rather than the max of Foo and the max of Foo2 - which is NOT the same thing) then the following will usually work better than a subquery:

SELECT
     A.SalesOrderID,
     A.OrderDate,
     B1.Foo,
     B1.Foo2
FROM
     A
LEFT OUTER JOIN B AS B1 ON
     B1.SalesOrderID = A.SalesOrderID
LEFT OUTER JOIN B AS B2 ON
     B2.SalesOrderID = A.SalesOrderID AND
     B2.Foo > B1.Foo
WHERE
     B2.SalesOrderID IS NULL

You're basically saying, give me the row from B where I can't find any other row from B with the same SalesOrderID and a greater Foo.

you are using onclick which is javascript event. there is two ways

Javascript

<input type="button" value="Home" class="homebutton" id="btnHome" 
onClick="window.location = 'http://google.com'" />

Or PHP

create another page as redirect.php and put

<?php header('location : google.com') ?>

and insert this link on any page within the same directory

<a href="redirect.php">google<a/>

hope this helps its simplest!!

These answers are no longer recommended since try_files works faster than if in this context. Simply add try_files in your php location block to test if the file exists, otherwise return a 404.

location ~ \.php {
    try_files $uri =404;
    ...
}

in the end of your Index.js need to add this Code:

Here is complete library with the widget: https://github.com/opprime/EditTextField

To use it you should add the dependency:

compile 'com.optimus:editTextField:0.2.0'

In the layout.xml file you can play with the widget settings:

xmlns:app="http://schemas.android.com/apk/res-auto"

• app:clearButtonMode,can has such values: never always whileEditing unlessEditing

• app:clearButtonDrawable

Sample in action:

I faced same problem. This is what I did to resolve the issue.

1. Select Project and right click.
2. Click on properties.
3. Click on libraries tab.
4. Click on 'Add Jars'.
5. Add relevant jar for your error.

VS2019 > Tools > Options > Nuget Package Manager > General > Click on "Clear All Nuger Cache(s)"

A small example of what you're trying to achieve would probably be a class similar to what's underneath:

import java.util.Locale;

public class OperatingSystem
{
    private static String OS = System.getProperty("os.name", "unknown").toLowerCase(Locale.ROOT);

    public static boolean isWindows()
    {
        return OS.contains("win");
    }

    public static boolean isMac()
    {
        return OS.contains("mac");
    }

    public static boolean isUnix()
    {
        return OS.contains("nux");
    }
}

This particular implementation is quite reliable and should be universally applicable. Just copy and paste it into your class of choice.

Customizing CORS for Angular 5 and Spring Security (Cookie base solution)

On the Angular side required adding option flag withCredentials: true for Cookie transport:

constructor(public http: HttpClient) {
}

public get(url: string = ''): Observable<any> {
    return this.http.get(url, { withCredentials: true });
}

On Java server-side required adding CorsConfigurationSource for configuration CORS policy:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        // This Origin header you can see that in Network tab
        configuration.setAllowedOrigins(Arrays.asList("http:/url_1", "http:/url_2")); 
        configuration.setAllowedMethods(Arrays.asList("GET","POST"));
        configuration.setAllowedHeaders(Arrays.asList("content-type"));
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and()...
    }
}

Method configure(HttpSecurity http) by default will use corsConfigurationSource for http.cors()

Other answers assume you want to know it from a popup or background script.

In case you want to know the current URL from a content script, the standard JS way applies:

window.location.toString()

You can use properties of window.location to access individual parts of the URL, such as host, protocol or path.

try like below...

CASE 
WHEN currate.currentrate is null THEN 1
ELSE currate.currentrate
END as currentrate

I'd recommend reading the header directly from the driver, not through Spark. Two reasons for this: 1) It's a single line. There's no advantage to a distributed approach. 2) We need this line in the driver, not the worker nodes.

It goes something like this:

// Ridiculous amount of code to read one line.
val uri = new java.net.URI(filename)
val conf = sc.hadoopConfiguration
val fs = hadoop.fs.FileSystem.get(uri, conf)
val path = new hadoop.fs.Path(filename)
val stream = fs.open(path)
val source = scala.io.Source.fromInputStream(stream)
val header = source.getLines.head

Now when you make the RDD you can discard the header.

val csvRDD = sc.textFile(filename).filter(_ != header)

Then we can make an RDD from one column, for example:

val idx = header.split(",").indexOf(columnName)
val columnRDD = csvRDD.map(_.split(",")(idx))

I like @CHR15TO's answer, unlike other answers I've seen on other similar questions, that answer actually shows how to properly escape a user provided search string (rather than saying it would be necessary without showing how).

However, it's still quite clunky, and possibly relatively slower. So why not have a specific solution to what is likely a common requirement for coders? (And why not include it in the ES6 API BTW?)

My answer [https://stackoverflow.com/a/38290557/887092] on a similar question enables the following:

var haystack = 'A. BAIL. Of. Hay.';
var needle = 'bail.';
var index = haystack.naturalIndexOf(needle);

Genghis Command Line Parser may be a little out of date, but it is very feature complete and works pretty well for me.

Linux & Windows (WSL)

When using the Windows Subsystem for Linux (e.g. Ubuntu/Debian on WSL) the xclip solution won't work. Instead you need to use clip.exe and powershell.exe to copy into and paste from the Windows clipboard.

.bashrc

This solution works on "real" Linux-based systems (i.e. Ubuntu, Debian) as well as on WSL systems. Just put the following code into your .bashrc:

if grep -q -i microsoft /proc/version; then
    # on WSL
    alias copy="clip.exe"
    alias paste="powershell.exe Get-Clipboard"
else
    # on "normal" linux
    alias copy="xclip -sel clip"
    alias paste="xclip -sel clip -o"
fi

How it works

The file /proc/version contains information about the currently running OS. When the system is running in WSL mode, then this file additionally contains the string Microsoft which is checked by grep.

Usage

To copy:

cat file | copy

And to paste:

paste > new_file

You can also just search on sites like Tucows and CNET, they have it there too.

In SQL Server 2012+, you can use OFFSET...FETCH:

SELECT
   <column(s)>
FROM
   <table(s)>
ORDER BY
   <sort column(s)>
OFFSET 1 ROWS   -- Skip this number of rows
FETCH NEXT 1 ROWS ONLY;  -- Return this number of rows

While ("run as SYSTEM") works, people should be advised this means going from a minimum-permissions type account to an account which has all permissions in the world. Which is very much not a recommended setup best practices or security-wise.

If you know what you are doing and know your SQL Server will always be run in an isolated environment (i.e. not on hotel or airport wifi) it's probably fine, but this creates a very real attack vector which can completely compromise a machine if on open internets.

This seems to be an error on Microsoft's part and people should be aware of the implications of the workaround posted.

First you have to install the Illuminate Html helper class:

composer require "illuminate/html":"5.0.*"

Next you need to open /config/app.php and update as follows:

'providers' => [

...

Illuminate\Html\HtmlServiceProvider::class,
],

'aliases' => [

...

'Form' => Illuminate\Html\FormFacade::class, 
'HTML' => Illuminate\Html\HtmlFacade::class,
],

To confirm it’s working use the following command:

php artisan tinker
> Form::text('foo')
"<input name=\"foo\" type=\"text\">"

To include external css in you files, use the following syntax:

{!! HTML::style('foo/bar.css') !!}

    private void textbox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            //cod for run
        }
    }

    private void buttonSearch_Click(object sender, EventArgs e)
    {
        textbox1_KeyDown(sender, new KeyEventArgs(Keys.Enter));
    }

In Android Studio 3.5.3, the Device File Explorer can be found in View -> Tool Windows.

It can also be opened using the vertical tabs on the right-hand side of the main window.

I modified the code and wrapped view update inside $apply().

link: function (scope, elem, attrs, ngModelCtrl){   
var updateModel = function(dateText){
    // call $apply to update the model
    scope.$apply(function(){
        ngModelCtrl.$setViewValue(dateText);
    });
};
var options = {
    dateFormat: "dd/mm/yy",
     // handle jquery date change
    onSelect: function(dateText){
        updateModel(dateText);
    }
};
 // jqueryfy the element
elem.datepicker(options);

}

This article is clearly explained, how to install MySqli with EachApache. This works for me too.

To install mysqli using EachApache:

1. Login to WHM as 'root' user.

2. Either search for "EasyApache" or go to Software > EasyApache

3. Scroll down and select a build option (Previously Saved Config)

4. Click Start "Start customizing based on profile"

5. Select the version of Apache and click "Next Step".

6. Select the version of PHP and click "Next Step".

7. Chose additional options within the "Short Options List"

8. Select "Exhaustive Options List" and look for "MySQL Improved extension"

9. Click "Save and Build"

Test e = static_cast<Test>(1);

This can be achieved purely with JavaScript.

I see the answer I wanted to write has been answered by lynx in comments to the question.

But I'm going to write answer anyway because just like me, people sometimes forget to read the comments.

So, if you just want to get an element's distance (in Pixels) from the top of your screen window, here is what you need to do:

// Fetch the element
var el = document.getElementById("someElement");  

use getBoundingClientRect()

// Use the 'top' property of 'getBoundingClientRect()' to get the distance from top
var distanceFromTop = el.getBoundingClientRect().top; 

Thats it!

Hope this helps someone :)

Here is what you do in Excel 2003:

1. In your sheet of interest, go to Format -> Sheet -> Hide and hide your sheet.
2. Go to Tools -> Protection -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Here is what you do in Excel 2007:

1. In your sheet of interest, go to Home ribbon -> Format -> Hide & Unhide -> Hide Sheet and hide your sheet.
2. Go to Review ribbon -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Once this is done, the sheet is hidden and cannot be unhidden without the password. Make sense?

If you really need to keep some calculations secret, try this: use Access (or another Excel workbook or some other DB of your choice) to calculate what you need calculated, and export only the "unclassified" results to your Excel workbook.

There are two ways to do this :

• Set the textbox's "multiline" property to true, in this case you don't want to do it so;
• Set a bigger font size to the textbox

I believe it is the only ways to do it; the bigger font size should automatically fit with the textbox

git reset --hard 4a155e5 Will move the HEAD back to where you want to be. There may be other references ahead of that time that you would need to remove if you don't want anything to point to the history you just deleted.

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7 was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.

For future reference: other than checking LD_LIBRARY_PATH, it's always a good idea to check a library with nm -D to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum revealed that the files were actually different.

Pylint message control is documented in the Pylint manual:

Is it possible to locally disable a particular message?

Yes, this feature has been added in Pylint 0.11. This may be done by adding # pylint: disable=some-message,another-one at the desired block level or at the end of the desired line of code.

You can use the message code or the symbolic names.

For example,

def test():
    # Disable all the no-member violations in this function
    # pylint: disable=no-member
    ...

global VAR # pylint: disable=global-statement

The manual also has further examples.

There is a wiki that documents all Pylint messages and their codes.

I had a similar error but with different context when I uploaded a *.p file to Google Drive. I tried to use it later in a Google Colab session, and got this error:

    1 with open("/tmp/train.p", mode='rb') as training_data:
----> 2     train = pickle.load(training_data)
UnpicklingError: invalid load key, '<'.

I solved it by compressing the file, upload it and then unzip on the session. It looks like the pickle file is not saved correctly when you upload/download it so it gets corrupted.

SELECT id FROM TAG_TABLE WHERE 'aaaaaaaa' LIKE '%' || "tag_name" || '%';

tag_name should be in quotation otherwise it will give error as tag_name doest not exist

Extracting contents between two known values can be useful for later as well. So why not create an extension method for it. Here is what i do, Short and simple...

  public static string GetBetween(this string content, string startString, string endString)
    {
        int Start=0, End=0;
        if (content.Contains(startString) && content.Contains(endString))
        {
            Start = content.IndexOf(startString, 0) + startString.Length;
            End = content.IndexOf(endString, Start);
            return content.Substring(Start, End - Start);
        }
        else
            return string.Empty;
    }

Well as simple, the answer according to me will be

first = list(prices)[0]

converting the dictionary to list will output the keys and we will select the first key from the list.

Token: Token is a sequence of characters that can be treated as a single logical entity. Typical tokens are,
1) Identifiers
2) keywords
3) operators
4) special symbols
5)constants

Pattern: A set of strings in the input for which the same token is produced as output. This set of strings is described by a rule called a pattern associated with the token.
Lexeme: A lexeme is a sequence of characters in the source program that is matched by the pattern for a token.

There's a new package called installr that can update your R version within R on the Windows platform. The package was built under version 3.2.3

From R Studio, click on Tools and select Install Packages... then type the name "installr" and click install. Alternatively, you may type install.packages("installr") in the Console.

Once R studio is done installing the package, load it by typing require(installr) in the Console.

To start the updating process for your R installation, type updateR(). This function will check for newer versions of R and if available, it will guide you through the decisions you need to make. If your R installation is up-to-date, it will return FALSE.

If you choose to download and install a newer version. There's an option for copying/moving all of your packages from the current R installation to the newer R installation which is very handy.

Quit and restart R Studio once the update process is over. R Studio will load the newer R version.

Follow this link if you wish to learn more on how to use the installr package.

This worked for me (win10), place before you import keras:

import os
os.environ['CUDA_VISIBLE_DEVICES'] = '-1'

It saves having to have methods that are only used once in a specific place from being defined far away from the place they are used. Good uses are as comparators for generic algorithms such as sorting, where you can then define a custom sort function where you are invoking the sort rather than further away forcing you to look elsewhere to see what you are sorting on.

And it's not really an innovation. LISP has had lambda functions for about 30 years or more.

30 minutes is 30 * 60 * 1000 miliseconds. Add that to the current date to specify an expiration date 30 minutes in the future.

 var date = new Date();
 var minutes = 30;
 date.setTime(date.getTime() + (minutes * 60 * 1000));
 $.cookie("example", "foo", { expires: date });

JSONP is really a simply trick to overcome XMLHttpRequest same domain policy. (As you know one cannot send AJAX (XMLHttpRequest) request to a different domain.)

So - instead of using XMLHttpRequest we have to use script HTMLl tags, the ones you usually use to load JS files, in order for JS to get data from another domain. Sounds weird?

Thing is - turns out script tags can be used in a fashion similar to XMLHttpRequest! Check this out:

script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://www.someWebApiServer.com/some-data";

You will end up with a script segment that looks like this after it loads the data:

<script>
{['some string 1', 'some data', 'whatever data']}
</script>

However this is a bit inconvenient, because we have to fetch this array from script tag. So JSONP creators decided that this will work better (and it is):

script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://www.someWebApiServer.com/some-data?callback=my_callback";

Notice my_callback function over there? So - when JSONP server receives your request and finds callback parameter - instead of returning plain JS array it'll return this:

my_callback({['some string 1', 'some data', 'whatever data']});

See where the profit is: now we get automatic callback (my_callback) that'll be triggered once we get the data. That's all there is to know about JSONP: it's a callback and script tags.

NOTE:
These are simple examples of JSONP usage, these are not production ready scripts.

RAW JavaScript demonstration (simple Twitter feed using JSONP):

<html>
    <head>
    </head>
    <body>
        <div id = 'twitterFeed'></div>
        <script>
        function myCallback(dataWeGotViaJsonp){
            var text = '';
            var len = dataWeGotViaJsonp.length;
            for(var i=0;i<len;i++){
                twitterEntry = dataWeGotViaJsonp[i];
                text += '<p><img src = "' + twitterEntry.user.profile_image_url_https +'"/>' + twitterEntry['text'] + '</p>'
            }
            document.getElementById('twitterFeed').innerHTML = text;
        }
        </script>
        <script type="text/javascript" src="http://twitter.com/status/user_timeline/padraicb.json?count=10&callback=myCallback"></script>
    </body>
</html>

Basic jQuery example (simple Twitter feed using JSONP):

<html>
    <head>
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
        <script>
            $(document).ready(function(){
                $.ajax({
                    url: 'http://twitter.com/status/user_timeline/padraicb.json?count=10',
                    dataType: 'jsonp',
                    success: function(dataWeGotViaJsonp){
                        var text = '';
                        var len = dataWeGotViaJsonp.length;
                        for(var i=0;i<len;i++){
                            twitterEntry = dataWeGotViaJsonp[i];
                            text += '<p><img src = "' + twitterEntry.user.profile_image_url_https +'"/>' + twitterEntry['text'] + '</p>'
                        }
                        $('#twitterFeed').html(text);
                    }
                });
            })
        </script>
    </head>
    <body>
        <div id = 'twitterFeed'></div>
    </body>
</html>

JSONP stands for JSON with Padding. (very poorly named technique as it really has nothing to do with what most people would think of as “padding”.)

The "play" button is specifically for build and run (or test or profile, etc). The Archive action is intended to build for release and to generate an archive that is suitable for submission to the app store. If you want to skip that, you can choose Product > Build For > Archive to force the release build without actually archiving. To find the built product, expand the Products group in the Project navigator, right-click the product and choose to show in Finder.

That said, you can click and hold the play button for a menu of other build actions (including Build and Archive).

It seems that you can check the tabIndex property of an element to determine if it is focusable. An element that is not focusable has a tabindex of "-1".

Then you just need to know the rules for tab stops:

• tabIndex="1" has the highest priorty.
• tabIndex="2" has the next highest priority.
• tabIndex="3" is next, and so on.
• tabIndex="0" (or tabbable by default) has the lowest priority.
• tabIndex="-1" (or not tabbable by default) does not act as a tab stop.
• For two elements that have the same tabIndex, the one that appears first in the DOM has the higher priority.

Here is an example of how to build the list of tab stops, in sequence, using pure Javascript:

function getTabStops(o, a, el) {
    // Check if this element is a tab stop
    if (el.tabIndex > 0) {
        if (o[el.tabIndex]) {
            o[el.tabIndex].push(el);
        } else {
            o[el.tabIndex] = [el];
        }
    } else if (el.tabIndex === 0) {
        // Tab index "0" comes last so we accumulate it seperately
        a.push(el);
    }
    // Check if children are tab stops
    for (var i = 0, l = el.children.length; i < l; i++) {
        getTabStops(o, a, el.children[i]);
    }
}

var o = [],
    a = [],
    stops = [],
    active = document.activeElement;

getTabStops(o, a, document.body);

// Use simple loops for maximum browser support
for (var i = 0, l = o.length; i < l; i++) {
    if (o[i]) {
        for (var j = 0, m = o[i].length; j < m; j++) {
            stops.push(o[i][j]);
        }
    }
}
for (var i = 0, l = a.length; i < l; i++) {
    stops.push(a[i]);

We first walk the DOM, collecting up all tab stops in sequence with their index. We then assemble the final list. Notice that we add the items with tabIndex="0" at the very end of the list, after the items with a tabIndex of 1, 2, 3, etc.

For a fully working example, where you can tab around using the "enter" key, check out this fiddle.

It is worth noting that you can build upon Gavin Toweys answer by using multiple fields from across your query such as

SUM(table.field = 1 AND table2.field = 2)

You can also use this syntax for COUNT and I am sure other functions as well.

Up to and including Java 6 it was possible to do this using the Static Initialization Block as was pointed out in the question Printing message on Console without using main() method. For instance using the following code:

public class Foo {
    static {
         System.out.println("Message");
         System.exit(0);
    } 
}

The System.exit(0) lets the program exit before the JVM is looking for the main method, otherwise the following error will be thrown:

Exception in thread "main" java.lang.NoSuchMethodError: main

In Java 7, however, this does not work anymore, even though it compiles, the following error will appear when you try to execute it:

The program compiled successfully, but main class was not found. Main class should contain method: public static void main (String[] args).

Here an alternative is to write your own launcher, this way you can define entry points as you want.

In the article JVM Launcher you will find the necessary information to get started:

This article explains how can we create a Java Virtual Machine Launcher (like java.exe or javaw.exe). It explores how the Java Virtual Machine launches a Java application. It gives you more ideas on the JDK or JRE you are using. This launcher is very useful in Cygwin (Linux emulator) with Java Native Interface. This article assumes a basic understanding of JNI.

<> is equal to != i.e, both are used to represent the NOT EQUAL operation. For instance, email <> '' and email != '' are same.

Take selected value:

worksheet name = ordls
form control list box name = DEPDB1

selectvalue = ordls.Shapes("DEPDB1").ControlFormat.List(ordls.Shapes("DEPDB1").ControlFormat.Value)

The issue is that tuples are immutable, and lists are not. Consider the following

d = {}
li = [1,2,3]
d[li] = 5
li.append(4)

What should d[li] return? Is it the same list? How about d[[1,2,3]]? It has the same values, but is a different list?

Ultimately, there is no satisfactory answer. For example, if the only key that works is the original key, then if you have no reference to that key, you can never again access the value. With every other allowed key, you can construct a key without a reference to the original.

If both of my suggestions work, then you have very different keys that return the same value, which is more than a little surprising. If only the original contents work, then your key will quickly go bad, since lists are made to be modified.

Try umount -f /mnt/share. Works OK with NFS, never tried with cifs.

Also, take a look at autofs, it will mount the share only when accessed, and will unmount it afterworlds.

There is a good tutorial at www.howtoforge.net

Here are some more tests

True if string is not empty:

[ -n "$var" ]
[[ -n $var ]]
test -n "$var"
[ "$var" ]
[[ $var ]]
(( ${#var} ))
let ${#var}
test "$var"

True if string is empty:

[ -z "$var" ]
[[ -z $var ]]
test -z "$var"
! [ "$var" ]
! [[ $var ]]
! (( ${#var} ))
! let ${#var}
! test "$var"

You can include git repository to composer.json like this:

"repositories": [
{
    "type": "package",
    "package": {
        "name": "example-package-name", //give package name to anything, must be unique
        "version": "1.0",
        "source": {
            "url": "https://github.com/example-package-name.git", //git url
            "type": "git",
            "reference": "master" //git branch-name
        }
    }
}],
"require" : {
  "example-package-name": "1.0"
}

Try to use this one

var result= stringToReplace.replace(/[^\w\s]/g, '')

[^] is for negation, \w for [a-zA-Z0-9_] word characters and \s for space, /[]/g for global

This is how I do it with an array Func<>:

var tasks = new Func<Task>[]
{
   () => myAsyncWork1(),
   () => myAsyncWork2(),
   () => myAsyncWork3()
};

await Task.WhenAll(tasks.Select(task => task()).ToArray()); //Async    
Task.WaitAll(tasks.Select(task => task()).ToArray()); //Or use WaitAll for Sync

gcc is a rich and complex "orchestrating" program that calls many other programs to perform its duties. For the specific purpose of seeing where #include "goo" and #include <zap> will search on your system, I recommend:

$ touch a.c
$ gcc -v -E a.c
 ...
#include "..." search starts here:
#include <...> search starts here:
 /usr/local/include
 /usr/lib/gcc/i686-apple-darwin9/4.0.1/include
 /usr/include
 /System/Library/Frameworks (framework directory)
 /Library/Frameworks (framework directory)
End of search list.
# 1 "a.c"

This is one way to see the search lists for included files, including (if any) directories into which #include "..." will look but #include <...> won't. This specific list I'm showing is actually on Mac OS X (aka Darwin) but the commands I recommend will show you the search lists (as well as interesting configuration details that I've replaced with ... here;-) on any system on which gcc runs properly.

String[] split = data.split("\\|",-1);

This is not the actual requirement in all the time. The Drawback of above is show below:

Scenerio 1:
When all data are present:
    String data = "5|6|7||8|9|10|";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 7
    System.out.println(splt.length); //output: 8

When data is missing:

Scenerio 2: Data Missing
    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output: 8

Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.

    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output:7

What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.

You can also use vavr:

import io.vavr.collection.HashSet;

HashSet.of("a", "b").toJavaSet();

I just did a post on this. I used a similar idea as Michael Hohlios did. Only, I used Properties instead of using the "object parameter".

Binding Visibility to a bool value in WPF

Using Properties makes it more readable, in my opinion.

<local:BoolToVisibleOrHidden x:Key="BoolToVisConverter" Collapse="True" Reverse="True" />

You can push your local branch to a new remote branch like so:

git push origin master:test

(Assuming origin is your remote, master is your local branch name and test is the name of the new remote branch, you wish to create.)

If at the same time you want to set up your local branch to track the newly created remote branch, you can do so with -u (on newer versions of Git) or --set-upstream, so:

git push -u origin master:test

or

git push --set-upstream origin master:test

...will create a new remote branch, named test, in remote repository origin, based on your local master, and setup your local master to track it.

public ChannelSearchEnum[] getChannelSearchEnum(Response response) {
        return response.as(ChannelSearchEnum[].class, ObjectMapperType.GSON);
}

Above will solve and passing response will returned mapped object array of the class

This is the way to disable all constraints from a specific view

 NSLayoutConstraint.deactivate(myView.constraints)

The answer to this may depend largely on the UUID version.

Many UUID generators use a version 4 random number. However, many of these use Pseudo a Random Number Generator to generate them.

If a poorly seeded PRNG with a small period is used to generate the UUID I would say it's not very safe at all. Some random number generators also have poor variance. i.e. favouring certain numbers more often than others. This isn't going to work well.

Therefore, it's only as safe as the algorithms used to generate it.

On the flip side, if you know the answer to these questions then I think a version 4 uuid should be very safe to use. In fact I'm using it to identify blocks on a network block file system and so far have not had a clash.

In my case, the PRNG I'm using is a mersenne twister and I'm being careful with the way it's seeded which is from multiple sources including /dev/urandom. Mersenne twister has a period of 2^19937 - 1. It's going to be a very very long time before I see a repeat uuid.

So pick a good library or generate it yourself and make sure you use a decent PRNG algorithm.

Issue:

.Net application code aborts before it starts its execution [Console application or Windows application]

Error received: Aborted with Error code "E0434352"

Exception: Unknown exception

Scenario 1:

When an application is already executed, which have used some of the dependent resources and those resources are still in use with the application executed, when another application or the same exe is triggered from some other source then one of the app throws the error

Scenario 2:

When an application is triggered by scheduler or automatic jobs, it may be in execution state at background, meanwhile when you try to trigger the same application again, the error may be triggered.

Solution:

Create an application, when & where the application release all its resources as soon as completed Kill all the background process once the application is closed Check and avoid executing the application from multiple sources like Batch Process, Task Scheduler and external tools at same time. Check for the Application and resource dependencies and clean up the code if needed.
