Programs & Examples On #Tbitmap

I use this library, it's really great when you have to deal with lots of images. It downloads them asynchronously, caches them etc.

As for the OOM exceptions, using this and this class drastically reduced them for me.

Find below link this solution is The best https://www.samieltamawy.com/how-to-fix-the-camera-intent-rotated-image-in-android/

I tried the solutions above and none worked for me out of the box.

However http://www.baeldung.com/httpclient-post-http-request. Line 6 POST Multipart Request worked within seconds

public void whenSendMultipartRequestUsingHttpClient_thenCorrect() 
  throws ClientProtocolException, IOException {
    CloseableHttpClient client = HttpClients.createDefault();
    HttpPost httpPost = new HttpPost("http://www.example.com");

    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.addTextBody("username", "John");
    builder.addTextBody("password", "pass");
    builder.addBinaryBody("file", new File("test.txt"),
      ContentType.APPLICATION_OCTET_STREAM, "file.ext");

    HttpEntity multipart = builder.build();
    httpPost.setEntity(multipart);

    CloseableHttpResponse response = client.execute(httpPost);
    client.close();
}

Using a ScaleGestureDetector

When learning a new concept I don't like using libraries or code dumps. I found a good description here and in the documentation of how to resize an image by pinching. This answer is a slightly modified summary. You will probably want to add more functionality later, but it will help you get started.

Layout

The ImageView just uses the app logo since it is already available. You can replace it with any image you like, though.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher"
        android:layout_centerInParent="true"/>

</RelativeLayout>

Activity

We use a ScaleGestureDetector on the activity to listen to touch events. When a scale (ie, pinch) gesture is detected, then the scale factor is used to resize the ImageView.

public class MainActivity extends AppCompatActivity {

    private ScaleGestureDetector mScaleGestureDetector;
    private float mScaleFactor = 1.0f;
    private ImageView mImageView;

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

        // initialize the view and the gesture detector
        mImageView = findViewById(R.id.imageView);
        mScaleGestureDetector = new ScaleGestureDetector(this, new ScaleListener());
    }

    // this redirects all touch events in the activity to the gesture detector
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mScaleGestureDetector.onTouchEvent(event);
    }

    private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {

        // when a scale gesture is detected, use it to resize the image
        @Override
        public boolean onScale(ScaleGestureDetector scaleGestureDetector){
            mScaleFactor *= scaleGestureDetector.getScaleFactor();
            mImageView.setScaleX(mScaleFactor);
            mImageView.setScaleY(mScaleFactor);
            return true;
        }
    }
}

Notes

• Although the activity had the gesture detector in the example above, it could have also been set on the image view itself.

• You can limit the size of the scaling with something like

  mScaleFactor = Math.max(0.1f, Math.min(mScaleFactor, 5.0f));
  

• Thanks again to Pinch-to-zoom with multi-touch gestures In Android

• Documentation
• Use Ctrl + mouse drag to simulate a pinch gesture in the emulator.

Going on

You will probably want to do other things like panning and scaling to some focus point. You can develop these things yourself, but if you would like to use a pre-made custom view, copy TouchImageView.java into your project and use it like a normal ImageView. It worked well for me and I only ran into one bug. I plan to further edit the code to remove the warning and the parts that I don't need. You can do the same.

You can used following code that can solve your problem.

Matrix matrix = new Matrix();
matrix.postScale(0.5f, 0.5f);
Bitmap croppedBitmap = Bitmap.createBitmap(bitmapOriginal, 100, 100,100, 100, matrix, true);

Above method do postScalling of image before cropping, so you can get best result with cropped image without getting OOM error.

How would I tint an image programmatically on the iPhone?

Use CSS background:transparent; to your button/div.

JSFiddle

First of all, you should never use the money datatype. If you do any calculations you will get truncated results. Run the following to see what I mean

DECLARE
    @mon1 MONEY,
    @mon2 MONEY,
    @mon3 MONEY,
    @mon4 MONEY,
    @num1 DECIMAL(19,4),
    @num2 DECIMAL(19,4),
    @num3 DECIMAL(19,4),
    @num4 DECIMAL(19,4)

    SELECT
    @mon1 = 100, @mon2 = 339, @mon3 = 10000,
    @num1 = 100, @num2 = 339, @num3 = 10000

    SET @mon4 = @mon1/@mon2*@mon3
    SET @num4 = @num1/@num2*@num3

    SELECT @mon4 AS moneyresult,
    @num4 AS numericresult

Output: 2949.0000 2949.8525

Now to answer your question (it was a little vague), the money datatype always has two places after the decimal point. Use the integer datatype if you don't want the fractional part or convert to int.

Perhaps you want to use the decimal or numeric datatype?

The documentation on CREATE EVENT is quite good, but it takes a while to get it right.

You have two problems, first, making the event recur, second, making it run at 13:00 daily.

This example creates a recurring event.

CREATE EVENT e_hourly
    ON SCHEDULE
      EVERY 1 HOUR
    COMMENT 'Clears out sessions table each hour.'
    DO
      DELETE FROM site_activity.sessions;

When in the command-line MySQL client, you can:

SHOW EVENTS;

This lists each event with its metadata, like if it should run once only, or be recurring.

The second problem: pointing the recurring event to a specific schedule item.

By trying out different kinds of expression, we can come up with something like:

CREATE EVENT IF NOT EXISTS `session_cleaner_event`
ON SCHEDULE
  EVERY 13 DAY_HOUR
  COMMENT 'Clean up sessions at 13:00 daily!'
  DO
    DELETE FROM site_activity.sessions;

arrayData.forEach((key : any, val: any) => {
                        key['index'] = val + 1;

                        arrayData2.forEach((keys : any, vals :any) => {
                            if (key.group_id == keys.id) {
                                key.group_name = keys.group_name;
                            }
                        })
                    })

For a non ASP.NET control, i.e. HTML controls like div, table, td, tr, etc. you need to first make them a server control, assign an ID, and then assign a property from server code:

        {

            border: 2px solid;
            border-radius: 5px;
            -moz-border-radius: 5px; /* Firefox 3.6 and earlier */
            border-color: #9c1c1f;
        }
    </style>
</head>

In python it means that the object can be members of sets in order to return a index. That is, they have unique identity/ id.

for example, in python 3.3:

the data structure Lists are not hashable but the data structure Tuples are hashable.

You may try:

    $('#GridName').data('kendoGrid').dataSource.read();
$('#GridName').data('kendoGrid').refresh();

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

If you do a straight git pull then you will either be 'fast-forwarded' or merge an unknown number of commits from the remote repository. This happens as one action though, so the last commit that you were at immediately before the pull will be the last entry in the reflog and can be accessed as HEAD@{1}. This means that you can do:

git diff HEAD@{1}

However, I would strongly recommend that if this is something you find yourself doing a lot then you should consider just doing a git fetch and examining the fetched branch before manually merging or rebasing onto it. E.g. if you're on master and were going to pull in origin/master:

git fetch

git log HEAD..origin/master

 # looks good, lets merge

git merge origin/master

Since iOS 8, you can't, it doesn't work because Apple changed internal implementation of UIActionSheet. Please refer to Apple Documentation:

Subclassing Notes

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

That's exactly what cursor: pointer; is supposed to do.

If you want the cursor to remain normal, you should be using cursor: default

There are really two separate issues. The first is keeping the elements of the array in proper order so that there are no "holes" after removing an element. The second is actually resizing the array itself.

Arrays in C are allocated as a fixed number of contiguous elements. There is no way to actually remove the memory used by an individual element in the array but the elements can be shifted to fill the hole made by removing an element. For example:

void remove_element(array_type *array, int index, int array_length)
{
   int i;
   for(i = index; i < array_length - 1; i++) array[i] = array[i + 1];
}

Statically allocated arrays can not be resized. Dynamically allocated arrays can be resized with realloc(). This will potentially move the entire array to another location in memory, so all pointers to the array or to its elements will have to be updated. For example:

remove_element(array, index, array_length);  /* First shift the elements, then reallocate */
array_type *tmp = realloc(array, (array_length - 1) * sizeof(array_type) );
if (tmp == NULL && array_length > 1) {
   /* No memory available */
   exit(EXIT_FAILURE);
}
array_length = array_length - 1;
array = tmp;

realloc will return a NULL pointer if the requested size is 0, or if there is an error. Otherwise it returns a pointer to the reallocated array. The temporary pointer is used to detect errors when calling realloc because instead of exiting it is also possible to just leave the original array as it was. When realloc fails to reallocate an array it does not alter the original array.

Note that both of these operations will be fairly slow if the array is large or if a lot of elements are removed. There are other data structures like linked lists and hashes that can be used if efficient insertion and deletion is a priority.

Uncomment the line extension=php_mysql.dll in your "php.ini" file and restart Apache.

Additionally, "libmysql.dll" file must be available to Apache, i.e., it must be either in available in Windows systems PATH or in Apache working directory.

See more about installing MySQL extension in manual.

P.S. I would advise to consider MySQL extension as deprecated and to use MySQLi or even PDO for working with databases (I prefer PDO).

If you are looking for a java-script library there's a javascript google maps v3 extension for the Polygon class to detect whether or not a point resides within it.

You can't create variables in CSS right now. If you want this sort of functionality you will need to use a CSS preprocessor like SASS or LESS. Here are your styles as they would appear in SASS:

$Color1:#fff;
$Color2:#b00;
$Color3:#050;

h1 {
    color:$Color1;
    background:$Color2;
}

They also allow you to do other (awesome) things like nesting selectors:

#some-id {
    color:red;

    &:hover {
        cursor:pointer;
    }
}

This would compile to:

#some-id { color:red; }
#some-id:hover { cursor:pointer; }

Check out the official SASS tutorial for setup instructions and more on syntax/features. Personally I use a Visual Studio extension called Web Workbench by Mindscape for easy developing, there are a lot of plugins for other IDEs as well.

Update

As of July/August 2014, Firefox has implemented the draft spec for CSS variables, here is the syntax:

:root {
  --main-color: #06c;
  --accent-color: #006;
}
/* The rest of the CSS file */
#foo h1 {
  color: var(--main-color);
}

Per the deferred PEP 396 (Module Version Numbers), there is a proposed way to do this. It describes, with rationale, an (admittedly optional) standard for modules to follow. Here's a snippet:

3) When a module (or package) includes a version number, the version SHOULD be available in the __version__ attribute.

4) For modules which live inside a namespace package, the module SHOULD include the __version__ attribute. The namespace package itself SHOULD NOT include its own __version__ attribute.

5) The __version__ attribute's value SHOULD be a string.

Yes, just delete the branch by running git push origin :branchname. To fix a new issue later, branch off from master again.

Python's dict has 'keys' method, and that is really useful. I think in JavaScript we can have something this:

function keys(){
    var k = [];
    for(var p in this) {
        if(this.hasOwnProperty(p))
            k.push(p);
    }
    return k;
}
Object.defineProperty(Object.prototype, "keys", { value : keys, enumerable:false });

EDIT: But the answer of @carlos-ruana works very well. I tested Object.keys(window), and the result is what I expected.

EDIT after 5 years: it is not good idea to extend Object, because it can conflict with other libraries that may want to use keys on their objects and it will lead unpredictable behavior on your project. @carlos-ruana answer is the correct way to get keys of an object.

DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month)

If you use all of the months in your code, your IDE won't let you compile, so I think you don't need unit testing.

But if you are using them with reflection, even if you delete one month, it will compile, so it's valid to put a unit test.

The easiest way to programmatically set a UIButton imageView in aspect fit mode :

Swift

button.contentHorizontalAlignment = .fill
button.contentVerticalAlignment = .fill
button.imageView?.contentMode = .scaleAspectFit

Objective-C

button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentFill;
button.contentVerticalAlignment = UIControlContentVerticalAlignmentFill;
button.imageView.contentMode = UIViewContentModeScaleAspectFit;

Note: You can change .scaleAspectFit (UIViewContentModeScaleAspectFit) to .scaleAspectFill (UIViewContentModeScaleAspectFill) to set an aspect fill mode

These are all great examples of how you clear a standard canvas, but if you are using paperjs, then this will work:

Define a global variable in JavaScript:

var clearCanvas = false;

From your PaperScript define:

function onFrame(event){
    if(clearCanvas && project.activeLayer.hasChildren()){
        project.activeLayer.removeChildren();
        clearCanvas = false;
    }
}

Now wherever you set clearCanvas to true, it will clear all the items from the screen.

I had trouble getting this to work and added another solution for anyone wanting/ needing to use FromCollection.

Instead of:

@Html.CheckBoxFor(model => true, item.TemplateId) 

Format html helper like so:

@Html.CheckBoxFor(model => model.SomeProperty, new { @class = "form-control", Name = "SomeProperty"})

Then in the viewmodel/model wherever your logic is:

public void Save(FormCollection frm)
{   
    // to do instantiate object.

    instantiatedItem.SomeProperty = (frm["SomeProperty"] ?? "").Equals("true", StringComparison.CurrentCultureIgnoreCase);

    // to do and save changes in database.
}

Are you thinking about something like this?

$('ul li').each(function(i)
{
   $(this).attr('rel'); // This is your rel value
});

For those who are newbie like me, Open IIS, expand your server name, choose sites, click on your website. On new install, it is Default web site. Click it. On the right side you have Default document option. Double click it. You will see default.htm, default.asp, index.htm etc.. to the extreme right click add. Enter the full name of your file(including extension) that you want to set it as default. click ok. Open cmd prompt as admin and reset iis. Remove all files from c:\inetpub\wwwroot folder like iisstart.html, index.html etc.

Note: This will automatically create web.config file in your c:\inetpub\wwwroot folder. I didnt have any web.config files in my inetpub or wwwroot folders. This automatically created one for me.

Next time when you enter http(s)://servername, it opens the default page you set.

SparkSQl support writing programs using Dataset and Dataframe API, along with it need to support sql.

In order to support Sql on DataFrames, first it requires a table definition with column names are required, along with if it creates tables the hive metastore will get lot unnecessary tables, because Spark-Sql natively resides on hive. So it will create a temporary view, which temporarily available in hive for time being and used as any other hive table, once the Spark Context stop it will be removed.

In order to create the view, developer need an utility called createOrReplaceTempView

You should create an App.config file (very similar to web.config).

You should right click on your project, add new item, and choose new "Application Configuration File".

Ensure that you add using System.Configuration in your project.

Then you can add values to it:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="setting1" value="key"/>
  </appSettings>
  <connectionStrings>
    <add name="prod" connectionString="YourConnectionString"/>
  </connectionStrings>
</configuration>

    private void Form1_Load(object sender, EventArgs e)
    {
        string setting = ConfigurationManager.AppSettings["setting1"];
        string conn = ConfigurationManager.ConnectionStrings["prod"].ConnectionString;
    }

Just a note: According to Microsoft, you should use ConfigurationManager instead of ConfigurationSettings (see the remarks section):

"The ConfigurationSettings class provides backward compatibility only. For new applications you should use the ConfigurationManager class or WebConfigurationManager class instead. "

Can you check value of i by putting logger or println(). and check with closing db conn at the end. Rest your code looks fine and it should work.

I faced the same issue with XAMPP and phpMyAdmin and this is how I solved it easily.

This is what I ended up doing in a Freeswitch bash startup script:

# Check if user exists
if ! id -u $FS_USER > /dev/null 2>&1; then
    echo "The user does not exist; execute below commands to crate and try again:"
    echo "  root@sh1:~# adduser --home /usr/local/freeswitch/ --shell /bin/false --no-create-home --ingroup daemon --disabled-password --disabled-login $FS_USER"
    echo "  ..."
    echo "  root@sh1:~# chown freeswitch:daemon /usr/local/freeswitch/ -R"
    exit 1
fi

def LongestEntry(lstName):
  totalEntries = len(lstName)
  currentEntry = 0
  longestLength = 0
  while currentEntry < totalEntries:
    thisEntry = len(str(lstName[currentEntry]))
    if int(thisEntry) > int(longestLength):
      longestLength = thisEntry
      longestEntry = currentEntry
    currentEntry += 1
  return longestLength

Just to share, I've developed my own script to do it. Feel free to use it. It generates "SELECT" statements that you can then run on the tables to generate the "INSERT" statements.

select distinct 'SELECT ''INSERT INTO ' + schema_name(ta.schema_id) + '.' + so.name + ' (' + substring(o.list, 1, len(o.list)-1) + ') VALUES ('

Extending @Tinker's answer,

In my case, I needed to make a command | command | command inside the -exec to print both the filename and the found text in files containing a certain text.

I was able to do it with:

find . -name config -type f \( -exec  grep "bitbucket" {} \; -a -exec echo {} \;  \) 

the result is:

    url = [email protected]:a/a.git
./a/.git/config
    url = [email protected]:b/b.git
./b/.git/config
    url = [email protected]:c/c.git
./c/.git/config

As mentioned here and here:

Set file encoding to UTF-8 and line-endings for new files to Unix, so that text files are saved in a format that is not specific to the Windows OS and most easily shared across heterogeneous developer desktops:

• Navigate to the Workspace preferences (General:Workspace)
• Change the Text File Encoding to UTF-8
• Change the New Text File Line Delimiter to Other and choose Unix from the pick-list

• Note: to convert the line endings of an existing file, open the file in Eclipse and choose File : Convert Line Delimiters to : Unix

Tip: You can easily convert existing file by selecting then in the Package Explorer, and then going to the menu entry File : Convert Line Delimiters to : Unix

Instead of using For each loop, use normal for loop. for example,the below code removes all the element in the array list without giving java.util.ConcurrentModificationException. You can modify the condition in the loop according to your use case.

for(int i=0; i<abc.size(); i++)  {
       e.remove(i);
 }

They differ in spelling only. There is no difference in what they refer to. To be technical you could say they differ in emphasis. Non blocking refers to control flow(it doesn't block.) Asynchronous refers to when the event\data is handled(not synchronously.)

You could use an extension method to get notified about changed property of an item in a collection in a generic way.

public static class ObservableCollectionExtension
{
    public static void NotifyPropertyChanged<T>(this ObservableCollection<T> observableCollection, Action<T, PropertyChangedEventArgs> callBackAction)
        where T : INotifyPropertyChanged
    {
        observableCollection.CollectionChanged += (sender, args) =>
        {
            //Does not prevent garbage collection says: http://stackoverflow.com/questions/298261/do-event-handlers-stop-garbage-collection-from-occuring
            //publisher.SomeEvent += target.SomeHandler;
            //then "publisher" will keep "target" alive, but "target" will not keep "publisher" alive.
            if (args.NewItems == null) return;
            foreach (T item in args.NewItems)
            {
                item.PropertyChanged += (obj, eventArgs) =>
                {
                    callBackAction((T)obj, eventArgs);
                };
            }
        };
    }
}

public void ExampleUsage()
{
    var myObservableCollection = new ObservableCollection<MyTypeWithNotifyPropertyChanged>();
    myObservableCollection.NotifyPropertyChanged((obj, notifyPropertyChangedEventArgs) =>
    {
        //DO here what you want when a property of an item in the collection has changed.
    });
}

For kotlin

 private fun isLocationEnabled(mContext: Context): Boolean {
    val lm = mContext.getSystemService(Context.LOCATION_SERVICE) as LocationManager
    return lm.isProviderEnabled(LocationManager.GPS_PROVIDER) || lm.isProviderEnabled(
            LocationManager.NETWORK_PROVIDER)
 }

dialog

private fun showLocationIsDisabledAlert() {
    alert("We can't show your position because you generally disabled the location service for your device.") {
        yesButton {
        }
        neutralPressed("Settings") {
            startActivity(Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS))
        }
    }.show()
}

call like this

 if (!isLocationEnabled(this.context)) {
        showLocationIsDisabledAlert()
 }

Hint: the dialog needs the following imports (android studio should handle this for you)

import org.jetbrains.anko.alert
import org.jetbrains.anko.noButton

And in the manifest you need the following permissions

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

It makes more sense to me to include the script after the HTML. Because most of the time I need the Dom to load before I execute my script. I could put it in the head tag but I don't like all the Document loading listener overhead. I want my code to be short and sweet and easy to read.

I've heard old versions of safari was quarky when adding your script outside of the head tag but I say who cares. I don't know anybody using that old crap do you.

Good question by the way.

Best answer doesn't work for me. I needed ssh:// from the beggining.

# does not work
git remote set-url origin [email protected]:10000/aaa/bbbb/ccc.git
# work
git remote set-url origin ssh://[email protected]:10000/aaa/bbbb/ccc.git

Based on Rubens' solution, you need to enable Delayed Expansion of env variables (type "help setlocal" or "help cmd") so that the var is correctly evaluated in the loop:

@echo off
setlocal enabledelayedexpansion
set myvar=the list: 
for /r %%i In (*.sql) DO set myvar=!myvar! %%i,
echo %myvar%

Also consider the following restriction (MSDN):

The maximum individual environment variable size is 8192bytes.

To call one constructor from another you need to use this() and you need to put it first. In your case the default constructor needs to call the one which takes an argument, not the other ways around.

In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.

Example:

select * from table order by [some_column] 
offset 10 rows
FETCH NEXT 10 rows only

As such, it is desirable to split the dataset into train and test sets in a way that preserves the same proportions of examples in each class as observed in the original dataset.

This is called a stratified train-test split.

We can achieve this by setting the “stratify” argument to the y component of the original dataset. This will be used by the train_test_split() function to ensure that both the train and test sets have the proportion of examples in each class that is present in the provided “y” array.

You can map JSON to specific class in Groovy using as operator:

import groovy.json.JsonSlurper

String json = '''
{
  "name": "John",  
  "age": 20
}
'''

def person = new JsonSlurper().parseText(json) as Person 

with(person) {
    assert name == 'John'
    assert age == 20
}

In the TENEX C Shell, tcsh, one can list a command's location(s), or if it is a built-in command, using the where command e.g.:

tcsh% where python
/usr/local/bin/python
/usr/bin/python

tcsh% where cd
cd is a shell built-in
/usr/bin/cd

Update:

So just to verify, it is not currently possible to set the click_action parameter via the Firebase Console.

So I've been trying to do this in the Firebase Notifications Console with no luck. Since I can't seem to find anywhere to place the click_action value in the console, what I mainly did to test this out is to add a custom key/value pair in the Notification (Advance Options > Custom Data):

Key: click_action
Value: <your_preferred_value>

then tried calling RemoteMessage.getNotification().getClickAction() in onMessageReceived() to see if it was retrieving the correct value, but it always returns null. So next I tried calling RemoteMessage.getData().get(< specified_key >) and was able to retrieve the value I added.

NOTE: I am not entirely sure if that is okay to be used as a workaround, or if it's against best practice. I would suggest using your own app server but your post is specific to the Firebase Console.

The way the client app and the notification behaves still depends on how you program it. With that said, I think you can use the above as a workaround, using the value retrieved from the getData(), then having the Notification call this or that. Hope this helps somehow. Cheers! :D

Another option can be to utilize the tagName property of the e.target. It doesn't apply exactly here, but let's say I have a class of something that's applied to either a DIV or an A tag, and I want to see if that class was clicked, and determine whether it was the DIV or the A that was clicked. I can do something like:

$('.example-class').click(function(e){
  if ((e.target.tagName.toLowerCase()) == 'a') {
    console.log('You clicked an A element.');
  } else { // DIV, we assume in this example
    console.log('You clicked a DIV element.');
  }
});

In my case, it was sufficient to drop the database which was hanging in state "Restoring..." with the SQL command

 drop database <dbname> 

in a query window.

Then I right-clicked on Databases and selected Refresh which removed the entry in Management Studio. Afterwards I did a new restore which worked fine (note that bringing it offline did not work, a restart of the SQL service did not work, a server reboot did not work as well).

This will create a Date exactly one year in the future with just one line. First we get the fullYear from a new Date, increment it, set that as the year of a new Date. You might think we'd be done there, but if we stopped it would return a timestamp, not a Date object so we wrap the whole thing in a Date constructor.

new Date(new Date().setFullYear(new Date().getFullYear() + 1))

You have to decide as which parameter you want to treat a single argument. You cannot treat it as both, content and options.

I see two possibilities:

1. Either change the order of your arguments, i.e. function(options, content)

2. Check whether options is defined:

   function(content, options) {
       if(typeof options === "undefined") {
           options = content;
           content = null;
       }
       //action
   }
   

   But then you have to document properly, what happens if you only pass one argument to the function, as this is not immediately clear by looking at the signature.

No, you can't do this in Java. Aside from anything else, d would then presumably be an instance of A (given the normal idea of "extends"), but users who only knew about A wouldn't know about it - which defeats the point of an enum being a well-known set of values.

If you could tell us more about how you want to use this, we could potentially suggest alternative solutions.

A popular Linux library which has similar functionality would be ncurses.

You can view these with Process Explorer from sysinternals. Use the "Find -> Find Handle or DLL..." option and enter the pattern "\Device\NamedPipe\". It will show you which processes have which pipes open.

You can do it with reduce:

a = [[1, 2, 3], [4, 5, 6], [7, 8, 9], [], [1, 2]]
print(reduce(lambda count, l: count + len(l), a, 0))
# result is 11

Use the System.Runtime.InteropServices.Marshal class:

String SecureStringToString(SecureString value) {
  IntPtr valuePtr = IntPtr.Zero;
  try {
    valuePtr = Marshal.SecureStringToGlobalAllocUnicode(value);
    return Marshal.PtrToStringUni(valuePtr);
  } finally {
    Marshal.ZeroFreeGlobalAllocUnicode(valuePtr);
  }
}

If you want to avoid creating a managed string object, you can access the raw data using Marshal.ReadInt16(IntPtr, Int32):

void HandleSecureString(SecureString value) {
  IntPtr valuePtr = IntPtr.Zero;
  try {
    valuePtr = Marshal.SecureStringToGlobalAllocUnicode(value);
    for (int i=0; i < value.Length; i++) {
      short unicodeChar = Marshal.ReadInt16(valuePtr, i*2);
      // handle unicodeChar
    }
  } finally {
    Marshal.ZeroFreeGlobalAllocUnicode(valuePtr);
  }
}

I will show you a whole example of servlet & how do ajax call.

Here, we are going to create the simple example to create the login form using servlet.

index.html

<form>  
   Name:<input type="text" name="username"/><br/><br/>  
   Password:<input type="password" name="userpass"/><br/><br/>  
   <input type="button" value="login"/>  
</form>  

Here is ajax Sample

       $.ajax
        ({
            type: "POST",           
            data: 'LoginServlet='+name+'&name='+type+'&pass='+password,
            url: url,
        success:function(content)
        {
                $('#center').html(content);           
            }           
        });

LoginServlet Servlet Code :-

    package abc.servlet;

import java.io.File;


public class AuthenticationServlet extends HttpServlet {

    private static final long serialVersionUID = 1L;

    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException
    {   
        doPost(request, response);
    }

    protected void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {

        try{
        HttpSession session = request.getSession();
        String username = request.getParameter("name");
        String password = request.getParameter("pass");

                /// Your Code
out.println("sucess / failer")
        } catch (Exception ex) {
            // System.err.println("Initial SessionFactory creation failed.");
            ex.printStackTrace();
            System.exit(0);
        } 
    }
}

The outcome can be summarized as

LinqToSql for small sites, and prototypes. It really saves time for Prototyping.

Sps : Universal. I can fine tune my queries and always check ActualExecutionPlan / EstimatedExecutionPlan.

I suspect that the problem is that the path is incorrect. Try this:

UserInput.prompt("Enter name of file to delete");
String name = UserInput.readString();
File file = new File("\\Files\\" + name + ".txt");
if (file.exists()) {
    file.delete();
} else {
    System.err.println(
        "I cannot find '" + file + "' ('" + file.getAbsolutePath() + "')");
}

In browsers up to and including IE9, this is done through conditional comments.

<!--[if IE]>
<style type="text/css">
  IE specific CSS rules go here
</style>
<![endif]-->

It is a build target that is not a filename.

If you add jars in tomcat's lib folder you can see this error

FragmentPagerAdapter: the fragment of each page the user visits will be stored in memory, although the view will be destroyed. So when the page is visible again, the view will be recreated but the fragment instance is not recreated. This can result in a significant amount of memory being used. FragmentPagerAdapter should be used when we need to store the whole fragment in memory. FragmentPagerAdapter calls detach(Fragment) on the transaction instead of remove(Fragment).

FragmentStatePagerAdapter: the fragment instance is destroyed when it is not visible to the User, except the saved state of the fragment. This results in using only a small amount of Memory and can be useful for handling larger data sets. Should be used when we have to use dynamic fragments, like fragments with widgets, as their data could be stored in the savedInstanceState.Also it won’t affect the performance even if there are large number of fragments.

Or, if you are looking for simple collection of errors for your apps.. here is my implementation of this:

public override void OnActionExecuting(HttpActionContext actionContext)
    {
        var modelState = actionContext.ModelState;

        if (!modelState.IsValid) 
        {

            var errors = new List<string>();
            foreach (var state in modelState)
            {
                foreach (var error in state.Value.Errors)
                {
                    errors.Add(error.ErrorMessage);
                }
            }

            var response = new { errors = errors };

            actionContext.Response = actionContext.Request
                .CreateResponse(HttpStatusCode.BadRequest, response, JsonMediaTypeFormatter.DefaultMediaType);
        }
    }

Error Message Response will look like:

{
  "errors": [
    "Please enter a valid phone number (7+ more digits)",
    "Please enter a valid e-mail address"
  ]
}

I know this is an old thread, but I like my own plugin that can cycle through whitespace modes (none, selection, and all) via a single shortcut. It also provides menu items under a View | Whitespace menu.

Hopefully people will find this useful - it is used by a lot of people :)

The pythonic way to read a file and put every lines in a list:

from __future__ import with_statement #for python 2.5
Names = []
with open('C:/path/txtfile.txt', 'r') as f:
    lines = f.readlines()
    Names.append(lines.strip())

I had the same problem even though openssl was enabled. The issue was that the Composer installer was looking at this config file:

C:\wamp\bin\php\php5.4.3\php.ini

But the config file that's loaded is actually here:

C:\wamp\bin\apache\apache2.2.22\bin\php.ini

So I just had to uncomment it in the first php.ini file and that did the trick. This is how WAMP was installed on my machine by default. I didn't go changing anything, so this will probably happen to others as well. This is basically the same as Augie Gardner's answer above, but I just wanted to point out that you might have two php.ini files.

I like prettyPhoto

prettyPhoto is a jQuery lightbox clone. Not only does it support images, it also support for videos, flash, YouTube, iframes and ajax. It’s a full blown media lightbox

There are a few tools that cooperate well and can make your debugging task easier.

Most important is the Django debug toolbar.

Then you need good logging using the Python logging facility. You can send logging output to a log file, but an easier option is sending log output to firepython. To use this you need to use the Firefox browser with the firebug extension. Firepython includes a firebug plugin that will display any server-side logging in a Firebug tab.

Firebug itself is also critical for debugging the Javascript side of any app you develop. (Assuming you have some JS code of course).

I also liked django-viewtools for debugging views interactively using pdb, but I don't use it that much.

There are more useful tools like dozer for tracking down memory leaks (there are also other good suggestions given in answers here on SO for memory tracking).

With es6 syntax you can use:

console.log(`x = ${x}`);

I want to propose a solution where both flavors of a many-to-many configuration can be achieved.

The "catch" is we need to create a view that targets the Join Table, since EF validates that a schema's table may be mapped at most once per EntitySet.

This answer adds to what's already been said in previous answers and doesn't override any of those approaches, it builds upon them.

The model:

public class Member
{
    public int MemberID { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }

    public virtual ICollection<Comment> Comments { get; set; }
    public virtual ICollection<MemberCommentView> MemberComments { get; set; }
}

public class Comment
{
    public int CommentID { get; set; }
    public string Message { get; set; }

    public virtual ICollection<Member> Members { get; set; }
    public virtual ICollection<MemberCommentView> MemberComments { get; set; }
}

public class MemberCommentView
{
    public int MemberID { get; set; }
    public int CommentID { get; set; }
    public int Something { get; set; }
    public string SomethingElse { get; set; }

    public virtual Member Member { get; set; }
    public virtual Comment Comment { get; set; }
}

The configuration:

using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity.ModelConfiguration;

public class MemberConfiguration : EntityTypeConfiguration<Member>
{
    public MemberConfiguration()
    {
        HasKey(x => x.MemberID);

        Property(x => x.MemberID).HasColumnType("int").IsRequired();
        Property(x => x.FirstName).HasColumnType("varchar(512)");
        Property(x => x.LastName).HasColumnType("varchar(512)")

        // configure many-to-many through internal EF EntitySet
        HasMany(s => s.Comments)
            .WithMany(c => c.Members)
            .Map(cs =>
            {
                cs.ToTable("MemberComment");
                cs.MapLeftKey("MemberID");
                cs.MapRightKey("CommentID");
            });
    }
}

public class CommentConfiguration : EntityTypeConfiguration<Comment>
{
    public CommentConfiguration()
    {
        HasKey(x => x.CommentID);

        Property(x => x.CommentID).HasColumnType("int").IsRequired();
        Property(x => x.Message).HasColumnType("varchar(max)");
    }
}

public class MemberCommentViewConfiguration : EntityTypeConfiguration<MemberCommentView>
{
    public MemberCommentViewConfiguration()
    {
        ToTable("MemberCommentView");
        HasKey(x => new { x.MemberID, x.CommentID });

        Property(x => x.MemberID).HasColumnType("int").IsRequired();
        Property(x => x.CommentID).HasColumnType("int").IsRequired();
        Property(x => x.Something).HasColumnType("int");
        Property(x => x.SomethingElse).HasColumnType("varchar(max)");

        // configure one-to-many targeting the Join Table view
        // making all of its properties available
        HasRequired(a => a.Member).WithMany(b => b.MemberComments);
        HasRequired(a => a.Comment).WithMany(b => b.MemberComments);
    }
}

The context:

using System.Data.Entity;

public class MyContext : DbContext
{
    public DbSet<Member> Members { get; set; }
    public DbSet<Comment> Comments { get; set; }
    public DbSet<MemberCommentView> MemberComments { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Configurations.Add(new MemberConfiguration());
        modelBuilder.Configurations.Add(new CommentConfiguration());
        modelBuilder.Configurations.Add(new MemberCommentViewConfiguration());

        OnModelCreatingPartial(modelBuilder);
     }
}

From Saluma's (@Saluma) answer

If you now want to find all comments of members with LastName = "Smith" for example you can write a query like this:

This still works...

var commentsOfMembers = context.Members
    .Where(m => m.LastName == "Smith")
    .SelectMany(m => m.MemberComments.Select(mc => mc.Comment))
    .ToList();

...but could now also be...

var commentsOfMembers = context.Members
    .Where(m => m.LastName == "Smith")
    .SelectMany(m => m.Comments)
    .ToList();

Or to create a list of members with name "Smith" (we assume there is more than one) along with their comments you can use a projection:

This still works...

var membersWithComments = context.Members
    .Where(m => m.LastName == "Smith")
    .Select(m => new
    {
        Member = m,
        Comments = m.MemberComments.Select(mc => mc.Comment)
    })
    .ToList();

...but could now also be...

var membersWithComments = context.Members
    .Where(m => m.LastName == "Smith")
    .Select(m => new
    {
        Member = m,
        m.Comments
    })
        .ToList();

If you want to remove a comment from a member

var comment = ... // assume comment from member John Smith
var member = ... // assume member John Smith

member.Comments.Remove(comment);

If you want to Include() a member's comments

var member = context.Members
    .Where(m => m.FirstName == "John", m.LastName == "Smith")
    .Include(m => m.Comments);

This all feels like syntactic sugar, however it does get you a few perks if you're willing to go through the additional configuration. Either way you seem to be able to get the best of both approaches.

for me, I do double click of ListView in this code section .

    this.listView.Activation = ItemActivation.TwoClick;

    this.listView.ItemActivate += ListView1_ItemActivate;

ItemActivate specify how user activate with items

When user do double click, ListView1_ItemActivate will be trigger. Property of ListView ItemActivate refers to access the collection of items selected.

    private void ListView1_ItemActivate(Object sender, EventArgs e)
    {

        foreach (ListViewItem item in listView.SelectedItems)
           //do something

    }

it works for me.

Yes - just explicitly provide the path to java.exe. For instance:

c:\Users\Jon\Test>"c:\Program Files\java\jdk1.6.0_03\bin\java.exe" -version
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

c:\Users\Jon\Test>"c:\Program Files\java\jdk1.6.0_12\bin\java.exe" -version
java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)

The easiest way to do this for a running command shell is something like:

set PATH=c:\Program Files\Java\jdk1.6.0_03\bin;%PATH%

For example, here's a complete session showing my default JVM, then the change to the path, then the new one:

c:\Users\Jon\Test>java -version
java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)

c:\Users\Jon\Test>set PATH=c:\Program Files\Java\jdk1.6.0_03\bin;%PATH%

c:\Users\Jon\Test>java -version
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

This won't change programs which explicitly use JAVA_HOME though.

Note that if you get the wrong directory in the path - including one that doesn't exist - you won't get any errors, it will effectively just be ignored.

The following should do it...

M-x load-file

You can use jQuery.children property.

var numItems = $('.wrapper').children('div').length;

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

To generate a certificate on the Apple provisioning profile website, firstly you have to generate keys on your mac, then upload the public key. Apple will generate your certificates with this key. When you download your certificates, tu be able to use them you need to have the private key.

The error "XCode could not find a valid private-key/certificate pair for this profile in your keychain." means you don't have the private key.

Maybe because your Mac was reinstalled, maybe because this key was generated on another Mac. So to be able to use your certificates, you need to find this key and install it on the keychain.

If you can not find it you can generate new keys restart this process on the provisioning profile website and get new certificates you will able to use.

Windows Services do not have UIs. You can redirect the output from a console app to your service with the code shown in this question.

You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.

Because you do not provide any context or code for your question it is not possible to give a direct answer.

I suggest you study how unicode and character encoding is done in Python:

• ReSharper - Majorly cool C# code analysis and refactoring features

You can use Date.getTime() which:

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

This means you can compare them just like numbers:

if (date1.getTime() <= date.getTime() && date.getTime() <= date2.getTime()) {
    /*
     * date is between date1 and date2 (both inclusive)
     */
}

/*
 * when date1 = 2015-01-01 and date2 = 2015-01-10 then
 * returns true for:
 * 2015-01-01
 * 2015-01-01 00:00:01
 * 2015-01-02
 * 2015-01-10
 * returns false for:
 * 2014-12-31 23:59:59
 * 2015-01-10 00:00:01
 * 
 * if one or both dates are exclusive then change <= to <

Reading the original comment, rutherford is looking for a cross-browser way to wrap unbroken text (inferred by his use of word-wrap for IE, designed to break unbroken strings).

/* Source: http://snipplr.com/view/10979/css-cross-browser-word-wrap */
.wordwrap { 
   white-space: pre-wrap;      /* CSS3 */   
   white-space: -moz-pre-wrap; /* Firefox */    
   white-space: -pre-wrap;     /* Opera <7 */   
   white-space: -o-pre-wrap;   /* Opera 7 */    
   word-wrap: break-word;      /* IE */
}

I've used this class for a bit now, and works like a charm. (note: I've only tested in FireFox and IE)

The most secure way (in terms of special character and data type handling) is using json_encode():

var spge = <?php echo json_encode($cname); ?>;

Do you mean like:

import groovy.json.*

class Me {
    String name
}

def o = new Me( name: 'tim' )

println new JsonBuilder( o ).toPrettyString()

For PostgreSQL 9.3 or less...Or who likes all normalized to text

Three flavors of my old SwissKnife library: relname_exists(anyThing), relname_normalized(anyThing) and relnamechecked_to_array(anyThing). All checks from pg_catalog.pg_class table, and returns standard universal datatypes (boolean, text or text[]).

/**
 * From my old SwissKnife Lib to your SwissKnife. License CC0.
 * Check and normalize to array the free-parameter relation-name.
 * Options: (name); (name,schema), ("schema.name"). Ignores schema2 in ("schema.name",schema2).
 */
CREATE FUNCTION relname_to_array(text,text default NULL) RETURNS text[] AS $f$
     SELECT array[n.nspname::text, c.relname::text]
     FROM   pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace,
            regexp_split_to_array($1,'\.') t(x) -- not work with quoted names
     WHERE  CASE
              WHEN COALESCE(x[2],'')>'' THEN n.nspname = x[1]      AND c.relname = x[2]
              WHEN $2 IS NULL THEN           n.nspname = 'public'  AND c.relname = $1
              ELSE                           n.nspname = $2        AND c.relname = $1
            END
$f$ language SQL IMMUTABLE;

CREATE FUNCTION relname_exists(text,text default NULL) RETURNS boolean AS $wrap$

$wrap$ language SQL IMMUTABLE;

CREATE FUNCTION relname_normalized(text,text default NULL,boolean DEFAULT true) RETURNS text AS $wrap$
  SELECT COALESCE(array_to_string(relname_to_array($1,$2), '.'), CASE WHEN $3 THEN '' ELSE NULL END)

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

I wrote a directive which lets you limit the areas where a click has effect. It could be used for certain scenarios like this one, so instead of having to deal with the click on a case by case basis you can just say "clicks won't come out of this element".

You would use it like this:

<table>
  <tr ng-repeat="user in users" ng-click="showUser(user)">
    <td>{{user.firstname}}</td>
    <td>{{user.lastname}}</td>
    <td isolate-click>
      <button class="btn" ng-click="deleteUser(user.id, $index);">
        Delete
      </button>
    </td>              
  </tr>
</table>

Keep in mind that this would prevent all clicks on the last cell, not just the button. If that's not what you want you may want to wrap the button like this:

<span isolate-click>
    <button class="btn" ng-click="deleteUser(user.id, $index);">
        Delete
    </button>
</span>

Here is the directive's code:

angular.module('awesome', []).directive('isolateClick', function() {
    return {
        link: function(scope, elem) {
            elem.on('click', function(e){
                e.stopPropagation();
            });
        }
   };
});

You can't do a bulk-update in SSIS within a dataflow task with the OOB components.

The general pattern is to identify your inserts, updates and deletes and push the updates and deletes to a staging table(s) and after the Dataflow Task, use a set-based update or delete in an Execute SQL Task. Look at Andy Leonard's Stairway to Integration Services series. Scroll about 3/4 the way down the article to "Set-Based Updates" to see the pattern.

Stage data

Set based updates

You'll get much better performance with a pattern like this versus using the OLE DB Command transformation for anything but trivial amounts of data.

If you are into third party tools, I believe CozyRoc and I know PragmaticWorks have a merge destination component.

Subprocess module is a good module to launch subprocesses. You can use it to call shell commands as this:

subprocess.call(["ls","-l"]);
#basic syntax
#subprocess.call(args, *)

You can see its documentation here.

If you have your script written in some .sh file or a long string, then you can use os.system module. It is fairly simple and easy to call:

import os
os.system("your command here")
# or
os.system('sh file.sh')

This command will run the script once, to completion, and block until it exits.

to also check blank string, I suggest following

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<c:if test="${empty fn:trim(var1)}">

</c:if>

It also handles nulls

It doesn't look like the Rails API exposes methods to do this generically. You could try accessing the underlying connection and using it's methods, e.g. for MySQL:

st = ActiveRecord::Base.connection.raw_connection.prepare("update table set f1=? where f2=? and f3=?")
st.execute(f1, f2, f3)
st.close

I'm not sure if there are other ramifications to doing this (connections left open, etc). I would trace the Rails code for a normal update to see what it's doing aside from the actual query.

Using prepared queries can save you a small amount of time in the database, but unless you're doing this a million times in a row, you'd probably be better off just building the update with normal Ruby substitution, e.g.

ActiveRecord::Base.connection.execute("update table set f1=#{ActiveRecord::Base.sanitize(f1)}")

or using ActiveRecord like the commenters said.

Not directly. In fact, form elements in general are either problematic or impossible to style using CSS alone. the best approach is to:

1. hide the radio button using javascript.
2. Use javascript to add/display HTML that can be styled how you like e.g.
3. Define css rules for a selected state, which is triggered by adding a class "selected" to yuor span.
4. Finally, write javascript to make the radio button's state react to clicks on the span, and, vice versa, to get the span to react to changes in the radio button's state (for when users use the keyboard to access the form). the second part of this can be tricky to get to work across all browsers. I use something like the following (which also uses jQuery. I avoid adding extra spans too by styling and applying the "selected" class directly to the input labels).

javascript

var labels = $("ul.radioButtons).delegate("input", "keyup", function () { //keyboard use
        if (this.checked) {
            select($(this).parent());
        }
    }).find("label").bind("click", function (event) { //mouse use
        select($(this));
    });

function select(el) {
    labels.removeClass("selected");
    el.addClass("selected");
}

html

<ul class="radioButtons">
    <li>
        <label for="employee1">
            employee1
            <input type="radio" id="employee1" name="employee" />
        </label>
    </li>
    <li>
        <label for="employee2">
            employee1
            <input type="radio" id="employee2" name="employee" />
        </label>
    </li>
</ul>

Taking advantage of the fact that a click will always follow a touch event, here is what I did to get rid of the "ghost click" without having to use timeouts or global flags.

$('#buttonId').on('touchstart click', function(event){
    if ($(this).data("already")) {
        $(this).data("already", false);
        return false;
    } else if (event.type == "touchstart") {
        $(this).data("already", true);
    }
    //your code here
});

Basically whenever an ontouchstart event fires on the element, a flag a set and then subsequently removed (and ignored), when the click comes.

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

Over the years I've been honing a perfect set of headers for this that work brilliantly in all browsers that I know of

header("Pragma: must-revalidate");

header("Content-type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=$filename.csv");

The primary goal of a hashmap is to store a data set and provide near constant time lookups on it using a unique key. There are two common styles of hashmap implementation:

• Separate chaining: one with an array of buckets (linked lists)
• Open addressing: a single array allocated with extra space so index collisions may be resolved by placing the entry in an adjacent slot.

Separate chaining is preferable if the hashmap may have a poor hash function, it is not desirable to pre-allocate storage for potentially unused slots, or entries may have variable size. This type of hashmap may continue to function relatively efficiently even when the load factor exceeds 1.0. Obviously, there is extra memory required in each entry to store linked list pointers.

Hashmaps using open addressing have potential performance advantages when the load factor is kept below a certain threshold (generally about 0.7) and a reasonably good hash function is used. This is because they avoid potential cache misses and many small memory allocations associated with a linked list, and perform all operations in a contiguous, pre-allocated array. Iteration through all elements is also cheaper. The catch is hashmaps using open addressing must be reallocated to a larger size and rehashed to maintain an ideal load factor, or they face a significant performance penalty. It is impossible for their load factor to exceed 1.0.

Some key performance metrics to evaluate when creating a hashmap would include:

• Maximum load factor
• Average collision count on insertion
• Distribution of collisions: uneven distribution (clustering) could indicate a poor hash function.
• Relative time for various operations: put, get, remove of existing and non-existing entries.

Here is a flexible hashmap implementation I made. I used open addressing and linear probing for collision resolution.

If you're using a relatively new version of Python, you can also use a context manager, such as this one:

from __future__ import with_statement
from grizzled.os import working_directory

with working_directory(path_to_directory):
    # code in here occurs within the directory

# code here is in the original directory

UPDATE

If you prefer to roll your own:

import os
from contextlib import contextmanager

@contextmanager
def working_directory(directory):
    owd = os.getcwd()
    try:
        os.chdir(directory)
        yield directory
    finally:
        os.chdir(owd)

I suggest you first call shutil.copytree, and if an exception is thrown, then retry with shutil.copy.

Security is one aspect you missed.

With Websockets the data has to go via a central webserver which typically sees all the traffic and can access it.

With WebRTC the data is end-to-end encrypted and does not pass through a server (except sometimes TURN servers are needed, but they have no access to the body of the messages they forward).

Depending on your application this may or may not matter.

If you are sending large amounts of data, the saving in cloud bandwidth costs due to webRTC's P2P architecture may be worth considering too.

This is an extension method. See here for an explanation.

Extension methods allow developers to add new methods to the public contract of an existing CLR type, without having to sub-class it or recompile the original type. Extension Methods help blend the flexibility of "duck typing" support popular within dynamic languages today with the performance and compile-time validation of strongly-typed languages.

Extension Methods enable a variety of useful scenarios, and help make possible the really powerful LINQ query framework... .

it means that you can call

MyClass myClass = new MyClass();
int i = myClass.Foo();

rather than

MyClass myClass = new MyClass();
int i = Foo(myClass);

This allows the construction of fluent interfaces as stated below.

The lock screen works without keyguard i have tested it. The home button stops working and you can't get to task manager by holding the home key. I wish they didn't develop a new process when it used to be built into system ui or whatever. I don't see the need for the change and extra process

INTRODUCTION

This answer corrects the very broken but shockingly top voted answer of this thread (written by TheMarko):

#!/usr/bin/env bash

BASEDIR=$(dirname "$0")
echo "$BASEDIR"

WHY DOES USING dirname "$0" ON IT'S OWN NOT WORK?

dirname $0 will only work if user launches script in a very specific way. I was able to find several situations where this answer fails and crashes the script.

First of all, let's understand how this answer works. He's getting the script directory by doing

dirname "$0"

$0 represents the first part of the command calling the script (it's basically the inputted command without the arguments:

/some/path/./script argument1 argument2

$0="/some/path/./script"

dirname basically finds the last / in a string and truncates it there. So if you do:

  dirname /usr/bin/sha256sum

you'll get: /usr/bin

This example works well because /usr/bin/sha256sum is a properly formatted path but

  dirname "/some/path/./script"

wouldn't work well and would give you:

  BASENAME="/some/path/." #which would crash your script if you try to use it as a path

Say you're in the same dir as your script and you launch it with this command

./script   

$0 in this situation will be ./script and dirname $0 will give:

. #or BASEDIR=".", again this will crash your script

Using:

sh script

Without inputting the full path will also give a BASEDIR="."

Using relative directories:

 ../some/path/./script

Gives a dirname $0 of:

 ../some/path/.

If you're in the /some directory and you call the script in this manner (note the absence of / in the beginning, again a relative path):

 path/./script.sh

You'll get this value for dirname $0:

 path/. 

and ./path/./script (another form of the relative path) gives:

 ./path/.

The only two situations where basedir $0 will work is if the user use sh or touch to launch a script because both will result in $0:

 $0=/some/path/script

which will give you a path you can use with dirname.

THE SOLUTION

You'd have account for and detect every one of the above mentioned situations and apply a fix for it if it arises:

#!/bin/bash
#this script will only work in bash, make sure it's installed on your system.

#set to false to not see all the echos
debug=true

if [ "$debug" = true ]; then echo "\$0=$0";fi


#The line below detect script's parent directory. $0 is the part of the launch command that doesn't contain the arguments
BASEDIR=$(dirname "$0") #3 situations will cause dirname $0 to fail: #situation1: user launches script while in script dir ( $0=./script)
                                                                     #situation2: different dir but ./ is used to launch script (ex. $0=/path_to/./script)
                                                                     #situation3: different dir but relative path used to launch script
if [ "$debug" = true ]; then echo 'BASEDIR=$(dirname "$0") gives: '"$BASEDIR";fi                                 

if [ "$BASEDIR" = "." ]; then BASEDIR="$(pwd)";fi # fix for situation1

_B2=${BASEDIR:$((${#BASEDIR}-2))}; B_=${BASEDIR::1}; B_2=${BASEDIR::2}; B_3=${BASEDIR::3} # <- bash only
if [ "$_B2" = "/." ]; then BASEDIR=${BASEDIR::$((${#BASEDIR}-1))};fi #fix for situation2 # <- bash only
if [ "$B_" != "/" ]; then  #fix for situation3 #<- bash only
        if [ "$B_2" = "./" ]; then
                #covers ./relative_path/(./)script
                if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/${BASEDIR:2}"; else BASEDIR="/${BASEDIR:2}";fi
        else
                #covers relative_path/(./)script and ../relative_path/(./)script, using ../relative_path fails if current path is a symbolic link
                if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/$BASEDIR"; else BASEDIR="/$BASEDIR";fi
        fi
fi

if [ "$debug" = true ]; then echo "fixed BASEDIR=$BASEDIR";fi

You can choose:

if [[ $? -ne 0 ]]; then       # -ne: not equal

if ! [[ $? -eq 0 ]]; then     # -eq: equal

if [[ ! $? -eq 0 ]]; then

! inverts the return of the following expression, respectively.

There are two string methods for this, find() and index(). The difference between the two is what happens when the search string isn't found. find() returns -1 and index() raises ValueError.

Using find()

>>> myString = 'Position of a character'
>>> myString.find('s')
2
>>> myString.find('x')
-1

Using index()

>>> myString = 'Position of a character'
>>> myString.index('s')
2
>>> myString.index('x')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: substring not found

From the Python manual

string.find(s, sub[, start[, end]])
Return the lowest index in s where the substring sub is found such that sub is wholly contained in s[start:end]. Return -1 on failure. Defaults for start and end and interpretation of negative values is the same as for slices.

And:

string.index(s, sub[, start[, end]])
Like find() but raise ValueError when the substring is not found.

While creating the object for the progressbar check the following.

This fails:

dialog = new ProgressDialog(getApplicationContext());

While adding the activities context works..

dialog = new ProgressDialog(MainActivity.this);

This could be done using reshape. It is possible with dplyr though.

  colnames(df) <- gsub("\\.(.{2})$", "_\\1", colnames(df))
  colnames(df)[2] <- "Date"
  res <- reshape(df, idvar=c("id", "Date"), varying=3:8, direction="long", sep="_")
  row.names(res) <- 1:nrow(res)
  
   head(res)
  #  id       Date time       Q3.2       Q3.3
  #1  1 2009-01-01    1  1.3709584  0.4554501
  #2  2 2009-01-02    1 -0.5646982  0.7048373
  #3  3 2009-01-03    1  0.3631284  1.0351035
  #4  4 2009-01-04    1  0.6328626 -0.6089264
  #5  5 2009-01-05    1  0.4042683  0.5049551
  #6  6 2009-01-06    1 -0.1061245 -1.7170087

Or using dplyr

  library(tidyr)
  library(dplyr)
  colnames(df) <- gsub("\\.(.{2})$", "_\\1", colnames(df))

  df %>%
     gather(loop_number, "Q3", starts_with("Q3")) %>% 
     separate(loop_number,c("L1", "L2"), sep="_") %>% 
     spread(L1, Q3) %>%
     select(-L2) %>%
     head()
  #  id       time       Q3.2       Q3.3
  #1  1 2009-01-01  1.3709584  0.4554501
  #2  1 2009-01-01  1.3048697  0.2059986
  #3  1 2009-01-01 -0.3066386  0.3219253
  #4  2 2009-01-02 -0.5646982  0.7048373

  #6  2 2009-01-02 -1.7813084 -0.7838389

Update

With new version of tidyr, we can use pivot_longer to reshape multiple columns. (Using the changed column names from gsub above)

library(dplyr)
library(tidyr)
df %>% 
    pivot_longer(cols = starts_with("Q3"), 
          names_to = c(".value", "Q3"), names_sep = "_") %>% 
    select(-Q3)
# A tibble: 30 x 4
#      id time         Q3.2    Q3.3
#   <int> <date>      <dbl>   <dbl>
# 1     1 2009-01-01  0.974  1.47  
# 2     1 2009-01-01 -0.849 -0.513 
# 3     1 2009-01-01  0.894  0.0442
# 4     2 2009-01-02  2.04  -0.553 
# 5     2 2009-01-02  0.694  0.0972
# 6     2 2009-01-02 -1.11   1.85  
# 7     3 2009-01-03  0.413  0.733 
# 8     3 2009-01-03 -0.896 -0.271 
#9     3 2009-01-03  0.509 -0.0512
#10     4 2009-01-04  1.81   0.668 
# … with 20 more rows

NOTE: Values are different because there was no set seed in creating the input dataset

One of #a or #b needs to be not position:absolute, so that #box will grow to accommodate it.

So you can stop #a from being position:absolute, and still position #b over the top of it, like this:

 #box {_x000D_
        background-color: #000;_x000D_
        position: relative;     _x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }_x000D_
    _x000D_
    .a {_x000D_
        width: 210px;_x000D_
        background-color: #fff;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    .b {_x000D_
        width: 100px; /* So you can see the other one */_x000D_
        position: absolute;_x000D_
        top: 10px; left: 10px;_x000D_
        background-color: red;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    #after {_x000D_
        background-color: yellow;_x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }

    <div id="box">_x000D_
        <div class="a">Lorem</div>_x000D_
        <div class="b">Lorem</div>_x000D_
    </div>_x000D_
    <div id="after">Hello world</div>

(Note that I've made the widths different, so you can see one behind the other.)

Edit after Justine's comment: Then your only option is to specify the height of #box. This:

#box {
    /* ... */
    height: 30px;
}

works perfectly, assuming the heights of a and b are fixed. Note that you'll need to put IE into standards mode by adding a doctype at the top of your HTML

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
          "http://www.w3.org/TR/html4/strict.dtd">

before that works properly.

Have you tried this?

ALTER TABLE <table_name> MODIFY <col_name> VARCHAR(65353);

This will change the col_name's type to VARCHAR(65353)

I think

if (0 < i && i < 100) 

is more elegant. Looks like maths equation.

If you are looking for something special you can try:

Math.max(0, i) == Math.min(i, 100)

at least it uses library.

This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?

• Many providers support bearer tokens which are very weak security-wise. By making them short-lived and requiring refresh, they limit the time an attacker can abuse a stolen token.
• Large scale deployment don't want to perform a database lookup every API call, so instead they issue self-encoded access token which can be verified by decryption. However, this also means there is no way to revoke these tokens so they are issued for a short time and must be refreshed.
• The refresh token requires client authentication which makes it stronger. Unlike the above access tokens, it is usually implemented with a database lookup.

BTW if the distribution of values indicates that an index scan will not be the worth (for example if all the values are in 2012), the optimiser could still choose a full table scan. YMMV. Explain is your friend.

After hours of struggling, I solved it by including the following within app/build.gradle:

You can find the codes in the DB2 Information Center. Here's a definition of the -302 from the z/OS Information Center:

THE VALUE OF INPUT VARIABLE OR PARAMETER NUMBER position-number IS INVALID OR TOO LARGE FOR THE TARGET COLUMN OR THE TARGET VALUE

On Linux/Unix/Windows DB2, you'll look under SQL Messages to find your error message. If the code is positive, you'll look for SQLxxxxW, if it's negative, you'll look for SQLxxxxN, where xxxx is the code you're looking up.

Custom Tooltips with pure CSS - no JavaScript needed:

Example here (with code) / Full screen example

As an alternative to the default title attribute tooltips, you can make your own custom CSS tooltips using :before/:after pseudo elements and HTML5 data-* attributes.

Using the provided CSS, you can add a tooltip to an element using the data-tooltip attribute.

You can also control the position of the custom tooltip using the data-tooltip-position attribute (accepted values: top/right/bottom/left).

For instance, the following will add a tooltop positioned at the bottom of the span element.

<span data-tooltip="Custom tooltip text." data-tooltip-position="bottom">Custom bottom tooltip.</span>

How does this work?

You can display the custom tooltips with pseudo elements by retrieving the custom attribute values using the attr() function.

[data-tooltip]:before {
    content: attr(data-tooltip);
}

In terms of positioning the tooltip, just use the attribute selector and change the placement based on the attribute's value.

Example here (with code) / Full screen example

Full CSS used in the example - customize this to your needs.

    display: inline-block;

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

Unfortunately std::map::operator[] is a non-const member function, and you have a const reference.

You either need to change the signature of function or do:

MAP::const_iterator pos = map.find("string");
if (pos == map.end()) {
    //handle the error
} else {
    std::string value = pos->second;
    ...
}

operator[] handles the error by adding a default-constructed value to the map and returning a reference to it. This is no use when all you have is a const reference, so you will need to do something different.

You could ignore the possibility and write string value = map.find("string")->second;, if your program logic somehow guarantees that "string" is already a key. The obvious problem is that if you're wrong then you get undefined behavior.

This is because the port is already running in the background.So you can restart the eclipse and try again. OR open the file application.properties and change the value of 'server.port' to some other value like ex:- 8000/8181

The best practice is to explicitly list the columns:

Insert Into TableName(col1, col2,col2) Values(?, ?, ?)

Otherwise, your original insert will break if you add another column to your table.

This is the one. The session will last for 1440 seconds (24 minutes).

session.gc_maxlifetime  1440    1440

The KeyTool is part of the JDK. You'll find it, assuming you installed the JDK with default settings, in $JAVA_HOME/bin

Use array_shift function

$myarray = array_shift($myarray);

This will move array elements one level up and you can access any array element without using [0] key

echo $myarray['email'];  

will show [email protected]

there is a case statement, but i think the below is more accurate/efficient/easier to read for what you want.

select 
  product
  ,coalesce(t4.price,t2.price, t3.price) as price
from table1 t1
left join table1 t2 on t1.product = t2.product and t2.customer =2
left join table1 t3 on t1.product = t3.product and t3.company =3
left join table1 t4 on t1.product = t4.product and t4.project =1

It can be done by the following way.

n = 0

numbers = [0]

for i in range(0,11):
    print n,
    numbers.append(n)
    prev = numbers[-2]
    if n == 0:
        n = 1
    else:
        n = n + prev

Please put this code in head section

<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>

and use font-family: 'Lato', sans-serif; in your css. For example:

h1 {
    font-family: 'Lato', sans-serif;
    font-weight: 400;
}

Or you can use manually also

Generate .ttf font from fontSquiral

and can try this option

    @font-face {
        font-family: "Lato";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}

Called like this

body {
  font-family: 'Lato', sans-serif;
}

Grails is the way to go if you like to do the CRUD easily and create a quick prototype application, plays nice with Eclipse as well. Follow the 'Build your first Grails application' tutorial here http://grails.org/Tutorials and you can be up and running your own application in less than an hour.

On Windows 7 I solved this by going into my environment settings (try this link for how) and adding user variables http_proxy and https_proxy with my proxy details.

You are correct, but note that you can do it the other way around - use Android Wifi tethering that sets up the phone as a base station and connect to said base station from the laptop.

file = request.FILES['filename']
file.name           # Gives name
file.content_type   # Gives Content type text/html etc
file.size           # Gives file's size in byte
file.read()         # Reads file

IE9 currently lacks CSS3 gradient support. However, here is a nice workaround solution using PHP to return an SVG (vertical linear) gradient instead, which allows us to keep our design in our stylesheets.

<?php

$from_stop = isset($_GET['from']) ? $_GET['from'] : '000000';
$to_stop = isset($_GET['to']) ? $_GET['to'] : '000000';

header('Content-type: image/svg+xml; charset=utf-8');

echo '<?xml version="1.0"?>
';

?>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="100%" height="100%">
    <defs>
        <linearGradient id="linear-gradient" x1="0%" y1="0%" x2="0%" y2="100%">
            <stop offset="0%" stop-color="#<?php echo $from_stop; ?>" stop-opacity="1"/>
            <stop offset="100%" stop-color="#<?php echo $to_stop; ?>" stop-opacity="1"/>
        </linearGradient>
    </defs>
    <rect width="100%" height="100%" fill="url(#linear-gradient)"/>
</svg>

Simply upload it to your server and call the URL like so:

gradient.php?from=f00&to=00f

This can be used in conjunction with your CSS3 gradients like this:

.my-color {
    background-color: #f00;
    background-image: url(gradient.php?from=f00&to=00f);
    background-image: -webkit-gradient(linear, left top, left bottom, from(#f00), to(#00f));
    background-image: -webkit-linear-gradient(top, #f00, #00f);
    background-image: -moz-linear-gradient(top, #f00, #00f);
    background-image: linear-gradient(top, #f00, #00f);
}

If you need to target below IE9, you can still use the old proprietary 'filter' method:

.ie7 .my-color, .ie8 .my-color {
    filter: progid:DXImageTransform.Microsoft.Gradient(startColorStr="#ff0000", endColorStr="#0000ff");
}

Of course you can amend the PHP code to add more stops on the gradient, or make it more sophisticated (radial gradients, transparency etc.) but this is great for those simple (vertical) linear gradients.

I am an Ionic framework user and the one I found that would consistently provide the current controller's $scope is:

angular.element(document.querySelector('ion-view[nav-view="active"]')).scope()

I suspect this can be modified to fit most scenarios regardless of framework (or not) by finding the query that will target the specific DOM element(s) that are available only during a given controller instance.

I love the answers from Kiril V. Lyadvinsky and CC. but my problem was a little more specific than just case-insensitivity; I needed a lazy Unicode-supported command-line argument parser that could eliminate false-positives/negatives when dealing with alphanumeric string searches that could have special characters in the base string used to format alphanum keywords I was searching against, e.g., Wolfjäger shouldn't match jäger but <jäger> should.

It's basically just Kiril/CC's answer with extra handling for alphanumeric exact-length matches.

/* Undefined behavior when a non-alpha-num substring parameter is used. */
bool find_alphanum_string_CI(const std::wstring& baseString, const std::wstring& subString)
{
    /* Fail fast if the base string was smaller than what we're looking for */
    if (subString.length() > baseString.length()) 
        return false;

    auto it = std::search(
        baseString.begin(), baseString.end(), subString.begin(), subString.end(),
        [](char ch1, char ch2)
        {
            return std::toupper(ch1) == std::toupper(ch2);
        }
    );

    if(it == baseString.end())
        return false;

    size_t match_start_offset = it - baseString.begin();

    std::wstring match_start = baseString.substr(match_start_offset, std::wstring::npos);

    /* Typical special characters and whitespace to split the substring up. */
    size_t match_end_pos = match_start.find_first_of(L" ,<.>;:/?\'\"[{]}=+-_)(*&^%$#@!~`");

    /* Pass fast if the remainder of the base string where
       the match started is the same length as the substring. */
    if (match_end_pos == std::wstring::npos && match_start.length() == subString.length()) 
        return true;

    std::wstring extracted_match = match_start.substr(0, match_end_pos);

    return (extracted_match.length() == subString.length());
}

In addition:

AppDomain.CurrentDomain.BaseDirectory
Assembly.GetEntryAssembly().Location

You can style the option elements to some extent.

Using the * CSS tag you can style the options inside the box that is drawn by the system.

Example:

#ddlProducts *
{
 border-radius:15px;
 background-color:red;
}

That will look like this:

@VonC already gave a very nice answer, but for completeness here is a little script I have been using---and which also nukes any errand Docker processes should you have some:

#!/bin/bash

imgs=$(docker images | awk '/<none>/ { print $3 }')
if [ "${imgs}" != "" ]; then
   echo docker rmi ${imgs}
   docker rmi ${imgs}
else
   echo "No images to remove"
fi

procs=$(docker ps -a -q --no-trunc)
if [ "${procs}" != "" ]; then
   echo docker rm ${procs}
   docker rm ${procs}
else
   echo "No processes to purge"
fi

Edit -- just saw your comment about the performance problems associated with a potentially bad piece of input data. I don't know offhand how try/catch on parseInt compares to a regex. I would guess, based on very little hard knowledge, that regexes are not hugely performant, compared to try/catch, in Java.

Anyway, I'd just do this:

public Integer tryParse(Object obj) {
  Integer retVal;
  try {
    retVal = Integer.parseInt((String) obj);
  } catch (NumberFormatException nfe) {
    retVal = 0; // or null if that is your preference
  }
  return retVal;
}

I guess you're coming from a windows background. So i'll contrast them (i'm kind of new to linux too). I found user's reply to my comment, to be useful in figuring things out.

In Windows, a variable can be permanent or not. The term Environment variable includes a variable set in the cmd shell with the SET command, as well as when the variable is set within the windows GUI, thus set in the registry, and becoming viewable in new cmd windows. e.g. documentation for the set command in windows https://technet.microsoft.com/en-us/library/bb490998.aspx "Displays, sets, or removes environment variables. Used without parameters, set displays the current environment settings." In Linux, set does not display environment variables, it displays shell variables which it doesn't call/refer to as environment variables. Also, Linux doesn't use set to set variables(apart from positional parameters and shell options, which I explain as a note at the end), only to display them and even then only to display shell variables. Windows uses set for setting and displaying e.g. set a=5, linux doesn't.

In Linux, I guess you could make a script that sets variables on bootup, e.g. /etc/profile or /etc/.bashrc but otherwise, they're not permanent. They're stored in RAM.

There is a distinction in Linux between shell variables, and environment variables. In Linux, shell variables are only in the current shell, and Environment variables, are in that shell and all child shells.

You can view shell variables with the set command (though note that unlike windows, variables are not set in linux with the set command).

set -o posix; set (doing that set -o posix once first, helps not display too much unnecessary stuff). So set displays shell variables.

You can view environment variables with the env command

shell variables are set with e.g. just a = 5

environment variables are set with export, export also sets the shell variable

Here you see shell variable zzz set with zzz = 5, and see it shows when running set but doesn't show as an environment variable.

Here we see yyy set with export, so it's an environment variable. And see it shows under both shell variables and environment variables

$ zzz=5

$ set | grep zzz
zzz=5

$ env | grep zzz

$ export yyy=5

$ set | grep yyy
yyy=5

$ env | grep yyy
yyy=5

https://askubuntu.com/questions/26318/environment-variable-vs-shell-variable-whats-the-difference

Note- one point which elaborates a bit and is somewhat corrective to what i've written, is that, in linux bash, 'set' can be used to set "positional parameters" and "shell options/attributes", and technically both of those are variables, though the man pages might not describe them as such. But still, as mentioned, set won't set shell variables or environment variables). If you do set asdf then it sets $1 to asdf, and if you do echo $1 you see asdf. If you do set a=5 it won't set the variable a, equal to 5. It will set the positional parameter $1 equal to the string of "a=5". So if you ever saw set a=5 in linux it's probably a mistake unless somebody actually wanted that string a=5, in $1. The other thing that linux's set can set, is shell options/attributes. If you do set -o you see a list of them. And you can do for example set -o verbose, off, to turn verbose on(btw the default happens to be off but that makes no difference to this). Or you can do set +o verbose to turn verbose off. Windows has no such usage for its set command.

Sorry for the short answer but it is late. Google "oracle event 10046 sql trace". It would be best to trace an individual session because figuring which SQL belongs to which session from v$sql is no easy if it is shared sql and being used by multiple users.

If you want to impress your Oracle DBA friends, learn how to set an oracle trace with event 10046, interpret the meaning of the wait events and find the top cpu consumers.

Quest had a free product that allowed you to capture the SQL as it went out from the client side but not sure if it works with your product/version of Oracle. Google "quest oracle sql monitor" for this.

Good night.

I was looking for shortest way to draw an 1px line, as whole load of separated CSS is not the fastest or shortest solution.

Up to HTML5, the WAS a shorter way for 1px hr: <hr noshade> but.. The noshade attribute of <hr> is not supported in HTML5. Use CSS instead. (nor other attibutes used before, as size, width, align)...

Now, this one is quite tricky, but works well if most simple 1px hr needed:

Variation 1, BLACK hr: (best solution for black)

<hr style="border-bottom: 0px">

Output: FF, Opera - black / Safari - dark gray

Variation 2, GRAY hr (shortest!):

<hr style="border-top: 0px">

Output: Opera - dark gray / FF - gray / Safari - light gray

<hr style="border: none; border-bottom: 1px solid red;">

Output: Opera / FF / Safari : 1px red.

TypeScript supports structural typing (also called duck typing), meaning that types are compatible when they share the same members. Your problem is that Apple and Pear don't share all their members, which means that they are not compatible. They are however compatible to another type that has only the isDecayed: boolean member. Because of structural typing, you don' need to inherit Apple and Pear from such an interface.

There are different ways to assign such a compatible type:

Assign type during variable declaration

This statement is implicitly typed to Apple[] | Pear[]:

const fruits = fruitBasket[key];

You can simply use a compatible type explicitly in in your variable declaration:

const fruits: { isDecayed: boolean }[] = fruitBasket[key];

For additional reusability, you can also define the type first and then use it in your declaration (note that the Apple and Pear interfaces don't need to be changed):

type Fruit = { isDecayed: boolean };
const fruits: Fruit[] = fruitBasket[key];

Cast to compatible type for the operation

The problem with the given solution is that it changes the type of the fruits variable. This might not be what you want. To avoid this, you can narrow the array down to a compatible type before the operation and then set the type back to the same type as fruits:

const fruits: fruitBasket[key];
const freshFruits = (fruits as { isDecayed: boolean }[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

Or with the reusable Fruit type:

type Fruit = { isDecayed: boolean };
const fruits: fruitBasket[key];
const freshFruits = (fruits as Fruit[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

The advantage of this solution is that both, fruits and freshFruits will be of type Apple[] | Pear[].

You can try this:

int cleft = 1;
intaleft = 1;
private void button2_Click(object sender, EventArgs e) 
{
     TextBox txt = new TextBox();
     this.Controls.Add(txt);
     txt.Top = cleft * 40;
     txt.Size = new Size(200, 16);
     txt.Left = 150;
     cleft = cleft + 1;
     Label lbl = new Label();
     this.Controls.Add(lbl);
     lbl.Top = aleft * 40;
     lbl.Size = new Size(100, 16);
     lbl.ForeColor = Color.Blue;
     lbl.Text = "BoxNo/CardNo";
     lbl.Left = 70;
     aleft = aleft + 1;
     return;
}
private void btd_Click(object sender, EventArgs e)
{ 
    //Here you Delete Text Box One By One(int ix for Text Box)
    for (int ix = this.Controls.Count - 2; ix >= 0; ix--)
    //Here you Delete Lable One By One(int ix for Lable)

One of the following may cause the exception:

1. Add an empty public constructor to your Fields class, JAXB uses reflection to load your classes, that's why the exception is thrown.
2. Add separate getter and setter for your list.

My explanation uses elementary building blocks that helped me to understand. Note I am leveraging @Deepak Goyal's answer above since he provided clarity:

We were given a logical 32-bit address space (i.e. We have a 32 bit computer)

Consider a system with a 32-bit logical address space

• This means that every memory address can be 32 bits long.
• "A 32-bit entry can point to one of 2^32 physical page frames"[2], stated differently,
• "A 32-bit register can store 2^32 different values"

We were also told that

each page size is 4 KB

• 1 KB (kilobyte) = 1 x 1024 bytes = 2^10 bytes
• 4 x 1024 bytes = 2^2 x 2^10 bytes => 4 KB (i.e. 2^12 bytes)
• The size of each page is thus 4 KB (Kilobytes NOT kilobits).

As Depaak said, we calculate the number of pages in the page table with this formula:

Num_Pages_in_PgTable = Total_Possible_Logical_Address_Entries / page size 
Num_Pages_in_PgTable =         2^32                           /    2^12
Num_Pages_in_PgTable = 2^20 (i.e. 1 million) 

The authors go on to give the case where each entry in the page table takes 4 bytes. That means that the total size of the page table in physical memory will be 4MB:

Memory_Required_Per_Page = Size_of_Page_Entry_in_bytes x Num_Pages_in_PgTable
Memory_Required_Per_Page =           4                 x     2^20
Memory_Required_Per_Page =     4 MB (Megabytes)

So yes, each process would require at least 4MB of memory to run, in increments of 4MB.

Example

Now if a professor wanted to make the question a bit more challenging than the explanation from the book, they might ask about a 64-bit computer. Let's say they want memory in bits. To solve the question, we'd follow the same process, only being sure to convert MB to Mbits.

Let's step through this example.

Givens:

• Logical address space: 64-bit
• Page Size: 4KB
• Entry_Size_Per_Page: 4 bytes

Recall: A 64-bit entry can point to one of 2^64 physical page frames - Since Page size is 4 KB, then we still have 2^12 byte page sizes

• 1 KB (kilobyte) = 1 x 1024 bytes = 2^10 bytes
• Size of each page = 4 x 1024 bytes = 2^2 x 2^10 bytes = 2^12 bytes

How Many pages In Page Table?

`Num_Pages_in_PgTable = Total_Possible_Logical_Address_Entries / page size 
Num_Pages_in_PgTable =         2^64                            /    2^12
Num_Pages_in_PgTable =         2^52 
Num_Pages_in_PgTable =      2^2 x 2^50 
Num_Pages_in_PgTable =       4  x 2^50 `  

How Much Memory in BITS Per Page?

Memory_Required_Per_Page = Size_of_Page_Entry_in_bytes x Num_Pages_in_PgTable 
Memory_Required_Per_Page =   4 bytes x 8 bits/byte    x     2^52
Memory_Required_Per_Page =     32 bits                x   2^2 x 2^50
Memory_Required_Per_Page =     32 bits                x    4  x 2^50
Memory_Required_Per_Page =     128 Petabits

You can easily do this by using UIAlertController

let alertController = UIAlertController(
       title: "Your title", message: "Your message", preferredStyle: .alert)
let defaultAction = UIAlertAction(
       title: "Close Alert", style: .default, handler: nil)
//you can add custom actions as well 
alertController.addAction(defaultAction)

present(alertController, animated: true, completion: nil)

.

You can use some code like this, you can adjust a height and width as per your need

    protected void button_Click(object sender, EventArgs e)
    {
        // open a pop up window at the center of the page.
        ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'your_page.aspx', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);
    }

This is not valid TypeScript code. You can not have method invocations in the body of a class.

// INVALID CODE
export class AppComponent {
  public n: number = 1;
  setTimeout(function() {
    n = n + 10;
  }, 1000);
}

Instead move the setTimeout call to the constructor of the class. Additionally, use the arrow function => to gain access to this.

export class AppComponent {
  public n: number = 1;

  constructor() {
    setTimeout(() => {
      this.n = this.n + 10;
    }, 1000);
  }

}

In TypeScript, you can only refer to class properties or methods via this. That's why the arrow function => is important.

Strictly stated you must check all of the following: defined, not empty AND not None.

For "normal" variables it makes a difference if defined and set or not set. See foo and bar in the example below. Both are defined but only foo is set.

On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz and xyz.msg in the example below:

cat > test.yml <<EOF
- hosts: 127.0.0.1

  vars:
    foo: ""          # foo is defined and foo == '' and foo != None
    bar:             # bar is defined and bar != '' and bar == None

  tasks:

  - debug:
      msg : ""
    register: xyz    # xyz is defined and xyz != '' and xyz != None
                     # xyz.msg is defined and xyz.msg == '' and xyz.msg != None

  - debug:
      msg: "foo is defined and foo == '' and foo != None"
    when: foo is defined and foo == '' and foo != None

  - debug:
      msg: "bar is defined and bar != '' and bar == None"
    when: bar is defined and bar != '' and bar == None

  - debug:
      msg: "xyz is defined and xyz != '' and xyz != None"
    when: xyz is defined and xyz != '' and xyz != None
  - debug:
      msg: "{{ xyz }}"

  - debug:
      msg: "xyz.msg is defined and xyz.msg == '' and xyz.msg != None"
    when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
  - debug:
      msg: "{{ xyz.msg }}"

This approach is not correct beacuse of Google Server Overload. For more informations see https://gis.stackexchange.com/questions/15052/how-to-avoid-google-map-geocode-limit#answer-15365

By the way, if you wish to proceed anyway, here you can find a code that let you load multiple markers ajax sourced on google maps avoiding OVER_QUERY_LIMIT error.

I've tested on my onw server and it works!:

       lng: 12.337646,
    });

function loadMarkerTimeout(timeout) {
    setTimeout(loadMarker, timeout)
}

function loadMarker() { 
    map.setZoom(6);

When you assign a variable to empty curly braces {} eg: new_set = {}, it becomes a dictionary. To create an empty set, assign the variable to a 'set()' ie: new_set = set()

Even I logged in and checked all the configuration, it still does not work !!!

It turned out that when I build my docker, I forget to put my username before the repo name

docker build docker-meteor-build 

(build successfully)

And then when I pushed to my repository, I used

docker push myname/docker-meteor-build 

It will show the unauthorized authentication required

So, solution is then name of build and the push should be exactly the same

docker build myname/docker-meteor-build 
docker push myname/docker-meteor-build 

Are you sure, that specified database and table exists? Did you try to look at your database using any database client? For example command-line MySQL client bundled with MySQL server. Or if you a developer newbie, there are dozens of a GUI and web interface clients (HeidiSQL, MySQL Workbench, phpMyAdmin and many more). So first check, if your table creation script was successful and had created what it have to.

BTW why do you have a script for creating the database structure? It's usualy a nonrecurring operation, so write the script to do this is unneeded. It's useful only in case of need of repeatedly creating and manipulating the database structure on the fly.

A new test category I've just become aware of is the canary test. A canary test is an automated, non-destructive test that is run on a regular basis in a live environment, such that if it ever fails, something really bad has happened.

Examples might be:

• Has data that should only ever be available in development/testy appeared live?
• Has a background process failed to run?
• Can a user logon?

For eg: you are using two activity, if you want to switch over from Activity A to Activity B

Simply give like this.

          Intent intent = new Intent(A.this, B.class);
         startActivity(intent);
         finish();

In my case, I was using Google's Roboto font. So I had to import it at the beginning of my page with its proper weights.

<link href = "https://fonts.googleapis.com/css?family=Roboto+Mono|Roboto+Slab|Roboto:300,400,500,700" rel = "stylesheet" />

if (typeof jQuery == 'undefined') {
// or if ( ! window.jQuery)
// or if ( ! 'jQuery' in window)
// or if ( ! window.hasOwnProperty('jQuery'))    

  var script = document.createElement('script');
  script.type = 'text/javascript';
  script.src = '/libs/jquery.js';

  var scriptHook = document.getElementsByTagName('script')[0];
  scriptHook.parentNode.insertBefore(script, scriptHook);

}

After you attempt to include Google's copy from the CDN.

In HTML5, you don't need to set the type attribute.

You can also use...

window.jQuery || document.write('<script src="/libs/jquery.js"><\/script>');

None of the answers given answer the original question.

The question is how to separate a div into 2 columns using css.

All of the above answers actually embed 2 divs into a single div in order to simulate 2 columns. This is a bad idea because you won't be able to flow content into the 2 columns in any dynamic fashion.

So, instead of the above, use a single div that is defined to contain 2 columns using CSS as follows...

.two-column-div {
 column-count: 2;
}

assign the above as a class to a div, and it will actually flow its contents into the 2 columns. You can go further and define gaps between margins as well. Depending on the content of the div, you may need to mess with the word break values so your content doesn't get cut up between the columns.

You can use Perl style regular expressions as well. A digit is just \d then.

grep -Po "\\d+" filename

-P Interpret PATTERNS as Perl-compatible regular expressions (PCREs).

-o Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line.

SciChart for Android is a relative newcomer, but brings extremely fast high performance real-time charting to the Android platform.

Here are some ideas:

• Go with Approach #1 and resize the array to hold additional results or use a type that automatically resizes as neccessary (you don't mention what language you are using so I can't be more specific).
• You could execute both statements in Approach #1 within a transaction to guarantee the counts are the same both times if your database supports this.
• I'm not sure what you are doing with the data but if it is possible to process the results without storing all of them first this might be the best method.

Found a really helpful link for that. Using SQLCMD for this is really easier than solving this with a stored procedure

http://www.excel-sql-server.com/sql-server-export-to-excel-using-bcp-sqlcmd-csv.htm

to remove tickmarks entirely use:

ax.set_yticks([])
ax.set_xticks([])

otherwise ax.set_yticklabels([]) and ax.set_xticklabels([]) will keep tickmarks.

Edit the code to be as follows:

// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );

if( $moved ) {
  echo "Successfully uploaded";         
} else {
  echo "Not uploaded because of error #".$_FILES["file"]["error"];
}

It will give you one of the following error code values 1 to 8:

UPLOAD_ERR_INI_SIZE = Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.

UPLOAD_ERR_FORM_SIZE = Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.

UPLOAD_ERR_PARTIAL = Value: 3; The uploaded file was only partially uploaded.

UPLOAD_ERR_NO_FILE = Value: 4; No file was uploaded.

UPLOAD_ERR_NO_TMP_DIR = Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.

UPLOAD_ERR_CANT_WRITE = Value: 7; Failed to write file to disk. Introduced in PHP 5.1.0.

UPLOAD_ERR_EXTENSION = Value: 8; A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help.

You can use the gradle argument --project-cache-dir "/Users/whatever/.gradle/" to force the gradle cache directory.

In this way you can be darn sure you know what directory is being used (as well as create different caches for different projects)

You won't be able to convert it directly to long because of the decimal point i think you should convert it into decimal and then convert it into long something like this:

String strValue[i] = "1100.25";
long l1 = Convert.ToInt64(Convert.ToDecimal(strValue));

hope this helps!

I'll add 2 points:

• "IN" is effectively serial ORs with parentheses around them
• AND has precedence over OR in every language I know

So, the 2 expressions are simply not equal.

WHERE some_col in (1,2,3,4,5) AND some_other_expr
--to the optimiser is this
WHERE
     (
     some_col = 1 OR
     some_col = 2 OR 
     some_col = 3 OR 
     some_col = 4 OR 
     some_col = 5
     )
     AND
     some_other_expr

So, when you break the IN clause up, you split the serial ORs up, and changed precedence.

Try

function RadionButtonSelectedValueSet(name, SelectdValue) {
    $('input[name="' + name+ '"][value="' + SelectdValue + '"]').prop('checked', true);
}

also call the method on dom ready

<script type="text/javascript">
jQuery(function(){
    RadionButtonSelectedValueSet('RBLExperienceApplicable', '1');
})
</script>

Using http.createServer is very low-level and really not useful for creating web applications as-is.

A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express.

When you have, you can create a basic application to handle your form:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

You can make your form point to it using:

<form action="http://127.0.0.1:8080/myaction" method="post">

The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html). You could use Express to also serve static content, like index.html, using the express.static middleware.

Every class or interface can be used as a type in TypeScript.

 const date = new Date();

will already know about the date type definition as Date is an internal TypeScript object referenced by the DateConstructor interface.

And for the constructor you used, it is defined as:

interface DateConstructor {
    new(): Date;
    ...
}

To make it more explicit, you can use:

 const date: Date = new Date();

You might be missing the type definitions though, the Date is coming for my example from the ES6 lib, and in my tsconfig.json I have defined:

"compilerOptions": {
    "target": "ES6",
    "lib": [
        "es6",
        "dom"
    ],

You might adapt these settings to target your wanted version of JavaScript.

The Date is by the way an Interface from lib.es6.d.ts:

/** Enables basic storage and retrieval of dates and times. */

Edit: thanks to @superlogical, you can now find and improve the following code in github!

I wrote this class based on some ideas here. The columns width is optimal, an it can handle object arrays with this simple API:

static void Main(string[] args)
{
  IEnumerable<Tuple<int, string, string>> authors =
    new[]
    {
      Tuple.Create(1, "Isaac", "Asimov"),
      Tuple.Create(2, "Robert", "Heinlein"),
      Tuple.Create(3, "Frank", "Herbert"),
      Tuple.Create(4, "Aldous", "Huxley"),
    };

  Console.WriteLine(authors.ToStringTable(
    new[] {"Id", "First Name", "Surname"},
    a => a.Item1, a => a.Item2, a => a.Item3));

  /* Result:        
  | Id | First Name | Surname  |
  |----------------------------|
  | 1  | Isaac      | Asimov   |
  | 2  | Robert     | Heinlein |
  | 3  | Frank      | Herbert  |
  | 4  | Aldous     | Huxley   |
  */
}

Here is the class:

public static class TableParser
{
  public static string ToStringTable<T>(
    this IEnumerable<T> values,
    string[] columnHeaders,
    params Func<T, object>[] valueSelectors)
  {
    return ToStringTable(values.ToArray(), columnHeaders, valueSelectors);
  }

  public static string ToStringTable<T>(
    this T[] values,
    string[] columnHeaders,
    params Func<T, object>[] valueSelectors)
  {
    Debug.Assert(columnHeaders.Length == valueSelectors.Length);

    var arrValues = new string[values.Length + 1, valueSelectors.Length];

    // Fill headers
    for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
    {
      arrValues[0, colIndex] = columnHeaders[colIndex];
    }

    // Fill table rows
    for (int rowIndex = 1; rowIndex < arrValues.GetLength(0); rowIndex++)
    {
      for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
      {
        arrValues[rowIndex, colIndex] = valueSelectors[colIndex]
          .Invoke(values[rowIndex - 1]).ToString();
      }
    }

    return ToStringTable(arrValues);
  }

  public static string ToStringTable(this string[,] arrValues)
  {
    int[] maxColumnsWidth = GetMaxColumnsWidth(arrValues);
    var headerSpliter = new string('-', maxColumnsWidth.Sum(i => i + 3) - 1);

    var sb = new StringBuilder();
    for (int rowIndex = 0; rowIndex < arrValues.GetLength(0); rowIndex++)
    {
      for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
      {
        // Print cell
        string cell = arrValues[rowIndex, colIndex];
        cell = cell.PadRight(maxColumnsWidth[colIndex]);
        sb.Append(" | ");
        sb.Append(cell);
      }

      // Print end of line
      sb.Append(" | ");
      sb.AppendLine();

      // Print splitter
      if (rowIndex == 0)
      {
        sb.AppendFormat(" |{0}| ", headerSpliter);
        sb.AppendLine();
      }
    }

    return sb.ToString();
  }

  private static int[] GetMaxColumnsWidth(string[,] arrValues)
  {
    var maxColumnsWidth = new int[arrValues.GetLength(1)];
    for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
    {
      for (int rowIndex = 0; rowIndex < arrValues.GetLength(0); rowIndex++)
      {
        int newLength = arrValues[rowIndex, colIndex].Length;
        int oldLength = maxColumnsWidth[colIndex];

        if (newLength > oldLength)
        {
          maxColumnsWidth[colIndex] = newLength;
        }
      }
    }

    return maxColumnsWidth;
  }
}

Edit: I added a minor improvement - if you want the column headers to be the property name, add the following method to TableParser (note that it will be a bit slower due to reflection):

public static string ToStringTable<T>(
    this IEnumerable<T> values,
    params Expression<Func<T, object>>[] valueSelectors)
{
  var headers = valueSelectors.Select(func => GetProperty(func).Name).ToArray();
  var selectors = valueSelectors.Select(exp => exp.Compile()).ToArray();
  return ToStringTable(values, headers, selectors);
}

private static PropertyInfo GetProperty<T>(Expression<Func<T, object>> expresstion)
{
  if (expresstion.Body is UnaryExpression)
  {
    if ((expresstion.Body as UnaryExpression).Operand is MemberExpression)
    {
      return ((expresstion.Body as UnaryExpression).Operand as MemberExpression).Member as PropertyInfo;
    }
  }

  if ((expresstion.Body is MemberExpression))
  {
    return (expresstion.Body as MemberExpression).Member as PropertyInfo;
  }
  return null;
}

\r used for carriage return. (ASCII value is 13) \n used for new line. (ASCII value is 10)

Your question is not very clear.

• What's your code exactly doing? Give more code.
• What's the error you're getting?

You say you get a null-pointer. You cannot get a null pointer as a value returned by contains().

However you can get a NullPointerException if your list has not been initialized. By reading your question now, I'd say that what you show here is correct, but maybe you just didn't instantiate the list.

For this to work (to add a feed URL if it isn't already in the list):

if (!this.rssFeedURLs.contains(rssFeedURL)) {
    this.rssFeedURLs.add(rssFeedUrl);
}

then this declaration would do:

private ArrayList<String> rssFeedURLs = new ArrayList<String>();

or initialize your list later on, but before trying to access its methods:

rssFeedUrls = new ArrayList<String>();

Finally... Do you really need a List? Maybe a Set would be better if you don't want duplicates. Use a LinkedHashSet if preserving the ordering matters.

For some reason the above accepted answer does not work in New versions of Angular (V6).

for that use this..

async delay(ms: number) {
    await new Promise(resolve => setTimeout(()=>resolve(), ms)).then(()=>console.log("fired"));
}

above worked for me.

Usage:

this.delay(3000);

OR more accurate way

this.delay(3000).then(any=>{
     //your task after delay.
});

Based on the answer of @Xaver Kapeller I figured out a way to create scroll animation when new views appear on the screen (and also animation to hide them).

It goes from this state:

• Button
• Last Button

to

• Button
• Button 1
• Button 2
• Button 3
• Button 4
• Last Button

and viceversa.

So, when the user clicks on the first button, the elements "Button 1", "Button 2", "Button 3" and "Button 4" will appear using fade animation and the element "Last Button" will move down till end. The height of the layout will change as well, allowing using scroll view properly.

This is the code to show elements with animation:

private void showElements() {
    // Precondition
    if (areElementsVisible()) {
        Log.w(TAG, "The view is already visible. Nothing to do here");
        return;
    }

    // Animate the hidden linear layout as visible and set
    // the alpha as 0.0. Otherwise the animation won't be shown
    mHiddenLinearLayout.setVisibility(View.VISIBLE);
    mHiddenLinearLayout.setAlpha(0.0f);
    mHiddenLinearLayout
            .animate()
            .setDuration(ANIMATION_TRANSITION_TIME)
            .alpha(1.0f)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    super.onAnimationEnd(animation);
                    updateShowElementsButton();
                    mHiddenLinearLayout.animate().setListener(null);
                }
            })
    ;

    mLastButton
            .animate()
            .setDuration(ANIMATION_TRANSITION_TIME)
            .translationY(mHiddenLinearLayoutHeight);

    // Update the high of all the elements relativeLayout
    LayoutParams layoutParams = mAllElementsRelativeLayout.getLayoutParams();

    // TODO: Add vertical margins
    layoutParams.height = mLastButton.getHeight() + mHiddenLinearLayoutHeight;
}

and this is the code to hide elements of the animation:

private void hideElements() {
    // Precondition
    if (!areElementsVisible()) {
        Log.w(TAG, "The view is already non-visible. Nothing to do here");
        return;
    }

    // Animate the hidden linear layout as visible and set
    mHiddenLinearLayout
            .animate()
            .setDuration(ANIMATION_TRANSITION_TIME)
            .alpha(0.0f)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    Log.v(TAG, "Animation ended. Set the view as gone");
                    super.onAnimationEnd(animation);
                    mHiddenLinearLayout.setVisibility(View.GONE);
                    // Hack: Remove the listener. So it won't be executed when
                    // any other animation on this view is executed
                    mHiddenLinearLayout.animate().setListener(null);
                    updateShowElementsButton();
                }
            })
    ;

    mLastButton
            .animate()
            .setDuration(ANIMATION_TRANSITION_TIME)
            .translationY(0);

    // Update the high of all the elements relativeLayout
    LayoutParams layoutParams = mAllElementsRelativeLayout.getLayoutParams();

    // TODO: Add vertical margins
    layoutParams.height = mLastButton.getHeight();
}

Note there is a simple hack on the method to hide the animation. On the animation listener mHiddenLinearLayout, I had to remove the listener itself by using:

mHiddenLinearLayout.animate().setListener(null);

This is because once an animation listener is attached to an view, the next time when any animation is executed in this view, the listener will be executed as well. This might be a bug in the animation listener.

The source code of the project is on GitHub: https://github.com/jiahaoliuliu/ViewsAnimated

Happy coding!

Update: For any listener attached to the views, it should be removed after the animation ends. This is done by using

view.animate().setListener(null);

You can use savefig() to export to an image file:

plt.savefig('filename.png')

In addition, you can specify the dpi argument to some scalar value, for example:

plt.savefig('filename.png', dpi=300)

The center class must have a width in order to make auto margin work:

.center { margin: 0 auto; width: 400px; }

Then I would apply the center class to the video itself, not a container:

<video class='center' …>…</video>

Currently Angular CLI doesn't support the feature of renaming or refactoring code.

You can achieve such functionality with the help of some IDE.

Intellij, Eclipse, VSCode etc.. has default support the refactoring.

Nowadays VSCode is showing some uptrend,personally I'm a fan of this

Refactoring with VSCode

Determinig reference : - VS Code help you find all references of a variable by selecting variable and pressing shortcut SHIFT + F12. This works incredibly well with Type Script.

Renaming all instances of reference :- After finding all the references you can press F2 will open a popup and you can change the value and click enter this will update all the instances of reference.

Renaming files and imports You can rename a file and its import references with a plugin. More details can be found here

With above steps after renaming the variables and files you can achieve the angular component renaming.

In Express 4.x, there is an attachment() method to Response:

res.attachment();
// Content-Disposition: attachment

res.attachment('path/to/logo.png');
// Content-Disposition: attachment; filename="logo.png"
// Content-Type: image/png

I found the similar problem and found the solution and i have blogged about how to upload the file using JSP , In that example i have used the absolute path. Note that if you want to route to some other URL based location you can put a ESB like WSO2 ESB

The top answer is flawed in my opinion. Hopefully, no one is mass importing all of pandas into their namespace with from pandas import *. Also, the map method should be reserved for those times when passing it a dictionary or Series. It can take a function but this is what apply is used for.

So, if you must use the above approach, I would write it like this

df["A1"], df["A2"] = zip(*df["a"].apply(calculate))

There's actually no reason to use zip here. You can simply do this:

df["A1"], df["A2"] = calculate(df['a'])

This second method is also much faster on larger DataFrames

df = pd.DataFrame({'a': [1,2,3] * 100000, 'b': [2,3,4] * 100000})

DataFrame created with 300,000 rows

%timeit df["A1"], df["A2"] = calculate(df['a'])
2.65 ms ± 92.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

%timeit df["A1"], df["A2"] = zip(*df["a"].apply(calculate))
159 ms ± 5.24 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

60x faster than zip

In general, avoid using apply

Apply is generally not much faster than iterating over a Python list. Let's test the performance of a for-loop to do the same thing as above

%%timeit
A1, A2 = [], []
for val in df['a']:
    A1.append(val**2)
    A2.append(val**3)

df['A1'] = A1
df['A2'] = A2

298 ms ± 7.14 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

So this is twice as slow which isn't a terrible performance regression, but if we cythonize the above, we get much better performance. Assuming, you are using ipython:

%load_ext cython

%%cython
cpdef power(vals):
    A1, A2 = [], []
    cdef double val
    for val in vals:
        A1.append(val**2)
        A2.append(val**3)

    return A1, A2

%timeit df['A1'], df['A2'] = power(df['a'])
72.7 ms ± 2.16 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Directly assigning without apply

You can get even greater speed improvements if you use the direct vectorized operations.

%timeit df['A1'], df['A2'] = df['a'] ** 2, df['a'] ** 3
5.13 ms ± 320 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

This takes advantage of NumPy's extremely fast vectorized operations instead of our loops. We now have a 30x speedup over the original.

The simplest speed test with apply

The above example should clearly show how slow apply can be, but just so its extra clear let's look at the most basic example. Let's square a Series of 10 million numbers with and without apply

s = pd.Series(np.random.rand(10000000))

%timeit s.apply(calc)
3.3 s ± 57.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Without apply is 50x faster

%timeit s ** 2
66 ms ± 2 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
