How about:

def ExtractAlphanumeric(InputString):
    from string import ascii_letters, digits
    return "".join([ch for ch in InputString if ch in (ascii_letters + digits)])

This works by using list comprehension to produce a list of the characters in InputString if they are present in the combined ascii_letters and digits strings. It then joins the list together into a string.

Using Guava you can easily combine different type of criteria. For your specific solution you can use:

value = CharMatcher.inRange('0', '9')
        .or(CharMatcher.inRange('a', 'z')
        .or(CharMatcher.inRange('A', 'Z'))).retainFrom(value)

Try this:

select distinct a.FirstName, a.LastName, v.District
from AddTbl a 
  inner join ValTbl v
  on a.LastName = v.LastName
order by a.FirstName;

Or this (it does the same, but the syntax is different):

select distinct a.FirstName, a.LastName, v.District
from AddTbl a, ValTbl v
where a.LastName = v.LastName
order by a.FirstName;

We can check by isInteger function. ie number will return true and float return false

console.log(Number.isInteger(2)),<BR>

Will return true

console.log(Number.isInteger(2.5))

Will return false

DO NOT use this:

System.Environment.GetEnvironmentVariable("TEMP")

Environment variables can be overridden, so the TEMP variable is not necessarily the directory.

The correct way is to use System.IO.Path.GetTempPath() as in the accepted answer.

Alternatively open Info.plist as source code and add this:

<key>NSCameraUsageDescription</key>
<string>Camera usage description</string>

Use max width and max height. It will keep the aspect ratio

#container img 
{
 max-width: 250px;
 max-height: 250px;
}

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

This issue occurs again in Xcode 10.2. You must download and install the following package from Apple. It provides Swift 5 Runtime Support for Command Line Tools.

I would use the subprocess module to execute the command ps with appropriate options. By adding options you can modify which processes you see. Lot's of examples on subprocess on SO. This question answers how to parse the output of ps for example:)

You can, as one of the example answers showed also use the PSI module to access system information (such as the process table in this example).

First of all, you don't need to "clean up" strings and ints - they will be taken care of automatically by the garbage collector. The only thing that needs to be cleaned up in Dispose are unmanaged resources or managed recources that implement IDisposable.

However, assuming this is just a learning exercise, the recommended way to implement IDisposable is to add a "safety catch" to ensure that any resources aren't disposed of twice:

public void Dispose()
{
    Dispose(true);

    // Use SupressFinalize in case a subclass 
    // of this type implements a finalizer.
    GC.SuppressFinalize(this);   
}
protected virtual void Dispose(bool disposing)
{
    if (!_disposed)
    {
        if (disposing) 
        {
            // Clear all property values that maybe have been set
            // when the class was instantiated
            id = 0;
            name = String.Empty;
            pass = String.Empty;
        }

        // Indicate that the instance has been disposed.
        _disposed = true;   
    }
}

I hope this will help you

Create table :

create table users (id int,first_name varchar(10),last_name varchar(10));

Insert values into the table :

insert into users (id,first_name,last_name) values(1,'Abhishek','Anand');

We can do it this way -

mongo db_name --quiet --eval 'DBQuery.shellBatchSize = 2000; db.users.find({}).limit(2000).toArray()' > users.json

The shellBatchSize argument is used to determine how many rows is the mongo client allowed to print. Its default value is 20.

What's FAT?

FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.

The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.

What About VFAT?

Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.

When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.

An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.

You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.

FAT32

FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.

The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.

This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.

Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.

Note: This section of the quote/ article (1999) is out of date. Updated info quote below.

As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.

The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.

Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.

Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):

I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.

The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.

The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.

Cannot delete or update a parent row: a foreign key constraint fails (table1.user_role, CONSTRAINT FK143BF46A8dsfsfds@#5A6BD60 FOREIGN KEY (user_id) REFERENCES user (id))

What i did in two simple steps . first i delete the child row in child table like

mysql> delete from table2 where role_id = 2 && user_id =20;

Query OK, 1 row affected (0.10 sec)

and second step as deleting the parent

delete from table1 where id = 20;

Query OK, 1 row affected (0.12 sec)

By this i solve the Problem which means Delete Child then Delete parent

i Hope You got it. :)

try {
    File img = new File("somefile.png");
    BufferedImage image = ImageIO.read(img ); 
    System.out.println(image);
} catch (IOException e) { 
    e.printStackTrace(); 
}

Example output for my image file:

BufferedImage@5d391d: type = 5 ColorModel: #pixelBits = 24 
numComponents = 3 color 
space = java.awt.color.ICC_ColorSpace@50a649 
transparency = 1 
has alpha = false 
isAlphaPre = false 
ByteInterleavedRaster: 
width = 800 
height = 600 
#numDataElements 3 
dataOff[0] = 2

You can run System.out.println(object); on just about any object and get some information about it.

Sqlite helper class helps us to manage database creation and version management. SQLiteOpenHelper takes care of all database management activities. To use it,
1.Override onCreate(), onUpgrade() methods of SQLiteOpenHelper. Optionally override onOpen() method.
2.Use this subclass to create either a readable or writable database and use the SQLiteDatabase's four API methods insert(), execSQL(), update(), delete() to create, read, update and delete rows of your table.

Example to create a MyEmployees table and to select and insert records:

public class MyDatabaseHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "DBName";

    private static final int DATABASE_VERSION = 2;

    // Database creation sql statement
    private static final String DATABASE_CREATE = "create table MyEmployees
                                 ( _id integer primary key,name text not null);";

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Method is called during creation of the database
    @Override
    public void onCreate(SQLiteDatabase database) {
        database.execSQL(DATABASE_CREATE);
    }

    // Method is called during an upgrade of the database,
    @Override
    public void onUpgrade(SQLiteDatabase database,int oldVersion,int newVersion){
        Log.w(MyDatabaseHelper.class.getName(),
                         "Upgrading database from version " + oldVersion + " to "
                         + newVersion + ", which will destroy all old data");
        database.execSQL("DROP TABLE IF EXISTS MyEmployees");
        onCreate(database);
    }
}

Now you can use this class as below,

public class MyDB{  

    private MyDatabaseHelper dbHelper;  

    private SQLiteDatabase database;  

    public final static String EMP_TABLE="MyEmployees"; // name of table 

    public final static String EMP_ID="_id"; // id value for employee
    public final static String EMP_NAME="name";  // name of employee

    /** 
     * 
     * @param context 
     */  
    public MyDB(Context context){  
        dbHelper = new MyDatabaseHelper(context);  
        database = dbHelper.getWritableDatabase();  
    }


    public long createRecords(String id, String name){  
        ContentValues values = new ContentValues();  
        values.put(EMP_ID, id);  
        values.put(EMP_NAME, name);  
        return database.insert(EMP_TABLE, null, values);  
    }    

    public Cursor selectRecords() {
        String[] cols = new String[] {EMP_ID, EMP_NAME};  
        Cursor mCursor = database.query(true, EMP_TABLE,cols,null  
            , null, null, null, null, null);  
        if (mCursor != null) {  
            mCursor.moveToFirst();  
        }  
        return mCursor; // iterate to get each value.
    }
}

Now you can use MyDB class in you activity to have all the database operations. The create records will help you to insert the values similarly you can have your own functions for update and delete.

You could also do the following:

for path, subdirs, files in os.walk(dir_name):
    for name in files:
        if path == ".": #this will filter the files in the current directory
             #code here

To restart a running service:

net stop "service name" && net start "service name"

However, if you don't know if the service is running in the first place and want to restart or start it, use this:

net stop "service name" & net start "service name"

This works if the service is already running or not.

Can i use pHp to develop an android app?
Yes . for web development you can use Phonegap. "PHP , HTML"etc.
What are the ways this can be done:?
you can check couple of examples on the internet here is one of them "an easy way" Connect Android To MySQL

$day_number = date('N', $date);

This will return a 1 for Monday to 7 for Sunday, for the date that is stored in $date. Omitting the second argument will cause date() to return the number for the current day.

public void Each<T>(IEnumerable<T> items, Action<T> action)
{
    foreach (var item in items)
        action(item);
}

... and call it thusly:

Each(myList, i => Console.WriteLine(i));

I think this is along the lines of what you're looking for. It appears that you want to see the orderid, the subtotal for each item in the order and the total amount for the order.

select o1.orderID, o1.subtotal, sum(o2.UnitPrice * o2.Quantity) as order_total from
(
    select o.orderID, o.price * o.qty as subtotal
    from product p inner join orderitem o on p.ProductID= o.productID
    where o.orderID = @OrderId
)as o1
inner join orderitem o2 on o1.OrderID = o2.OrderID
group by o1.orderID, o1.subtotal

On my machine:

>>> print type(1<<30)
<type 'int'>
>>> print type(1<<31)
<type 'long'>
>>> print type(0x7FFFFFFF)
<type 'int'>
>>> print type(0x7FFFFFFF+1)
<type 'long'>

Python uses ints (32 bit signed integers, I don't know if they are C ints under the hood or not) for values that fit into 32 bit, but automatically switches to longs (arbitrarily large number of bits - i.e. bignums) for anything larger. I'm guessing this speeds things up for smaller values while avoiding any overflows with a seamless transition to bignums.

In my case, after some refactoring in EF6, my tests were failing with the same error message as the original poster but my solution had nothing to do with the DateTime fields.

I was just missing a required field when creating the entity. Once I added the missing field, the error went away. My entity does have two DateTime? fields but they weren't the problem.

Like Jonathan suggested, using textView.setTextTypeface works, I just used it in an app a few seconds ago.

JOIN t2 ON t1.id=t2.id AND t1.date=t2.date

To test for the existence of a command line paramater, use empty brackets:

IF [%1]==[] echo Value Missing

or

IF [%1] EQU [] echo Value Missing

The SS64 page on IF will help you here. Under "Does %1 exist?".

You can't set a positional parameter, so what you should do is do something like

SET MYVAR=%1

You can then re-set MYVAR based on its contents.

If you are not giving any modifier to your method then as default it will be Default modifier which has scope within package.

If performance is important go down to numpy level:

import numpy as np

df = pd.DataFrame({'a': np.random.randint(0, 60, 600), 'b': [1, 2, 5, 5, 4, 6]*100})

def f(df):
         keys, values = df.sort_values('a').values.T
         ukeys, index = np.unique(keys, True)
         arrays = np.split(values, index[1:])
         df2 = pd.DataFrame({'a':ukeys, 'b':[list(a) for a in arrays]})
         return df2

Tests:

In [301]: %timeit f(df)
1000 loops, best of 3: 1.64 ms per loop

In [302]: %timeit df.groupby('a')['b'].apply(list)
100 loops, best of 3: 5.26 ms per loop

use as at end of query

Select * into #temp (select * from table1,table2) as temp_table

func letterize() -> [Character] {
    return Array(self.characters)
}

This worked for me:

sudo apt-get install php5-sqlite

This installed sqlite for php5, then I ran the php artisan migrate command again and worked perfectly.

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 know this is an old thread but I have tried numerous things and fixed my issue using the following means..

I'm developing a cross platform app on Windows but to be used on Linux and Windows servers.

A MySQL database called "jtm" installed on both systems. For some reason, in my code I had the database name as "JTM". On Windows it worked fine, in fact on several Windows systems it flew along.

On Ubuntu I got the error above time and time again. I tested it out with the correct case in the code "jtm" and it works a treat.

Linux is obviously a lot less forgiving about case sensitivity (rightly so), whereas Windows makes allowances.

I feel a bit daft now but check everything. The error message is not the best but it does seem fixable if you persevere and get things right.

or you can inject the class inheritance "http" into React Component

via props object.

1. update :

   ReactDOM.render(<ReactApp data={app} />, document.getElementById('root'));
   

2. Simply edit React Component ReactApp like this:

   class ReactApp extends React.Component {
   
   state = {
   
       data: ''
   
   }
   
       render(){
   
       return (
           <div>
           {this.props.data.getData()}      
           </div>
   
       )
       }
   }
   

I think there are two ways you can handle that:

1. Check using something like firebug if there is a difference (in class, id, etc.) between the two buttons and use that to address the specific button
2. Use something like :first-child to select for example the first button and style that one differently

When I look at the source with firebug for one of my dialogs, it turns up something like:

<div class="ui-dialog-buttonpane ui-widget-content ui-helper-clearfix">
    <button class="ui-state-default ui-corner-all ui-state-focus" type="button">Send</button>
    <button class="ui-state-default ui-corner-all" type="button">Cancel</button>
</div>

So I could for example address the Send button by adding some styles to .ui-state-focus (with perhaps some additional selectors to make sure I override jquery's styles).

By the way, I´d go for the second option in this case to avoid problems when the focus changes...

Thank you all for your reply. I have got my script working with the module/ script written by Preston Landers way back in 2010. After two days of browsing the internet I could find the script as it was was deeply hidden in pywin32 mailing list. With this script it is easier to check if the user is admin and if not then ask for UAC/ admin right. It does provide output in separate windows to find out what the code is doing. Example on how to use the code also included in the script. For the benefit of all who all are looking for UAC on windows have a look at this code. I hope it helps someone looking for same solution. It can be used something like this from your main script:-

The if statement uses the results of a logical expression to decide if one of two code blocks will be executed.

With this code

if (logical expression) {
    code block 1;
} else {
    code block 2;
}

if the logical expression is true, only the statements in code block 1 will be executed; if false, only the statements in code block 2.

In the case that there are multiple similar tests to be done (for instance if we are testing a number to be less than zero, equal to zero or more than zero) then the second test can be placed as the first statement of the else code block.

if (logical expression 1) {
    code block 1;
} else {
    if (logical expression 2) {
        code block 2;
    } else {
        code block 3;
    }
}

In this case, code block 1 is executed if logical expression 1 is true; code block 2 if logical expression 1 is false and logical expression 2 is true; code block 3 if both logical expressions are false.

Obviously this can be repeated with another if statement as the first statement of code block 3.

The else if statement is simply a reformatted version of this code.

if (logical expression 1) {
    code block 1;
} else if (logical expression 2) {
    code block 2;
} else {
    code block 3;
}

From cppreference when incrementing iterators:

You should prefer pre-increment operator (++iter) to post-increment operator (iter++) if you are not going to use the old value. Post-increment is generally implemented as follows:

   Iter operator++(int)   {
     Iter tmp(*this); // store the old value in a temporary object
     ++*this;         // call pre-increment
     return tmp;      // return the old value   }

Obviously, it's less efficient than pre-increment.

Pre-increment does not generate the temporary object. This can make a significant difference if your object is expensive to create.

According to the DataTable help, I could done for my table.

I want wanted multiple database to my DataTable.

For example: data_1.json > 2500 records - data_2.json > 300 records - data_3.json > 10265 records

var table;
var isTableCreated= false;

if (isTableCreated==true) {
    table.destroy();
    $('#Table').empty(); // empty in case the columns change
}
else
    i++;

table = $('#Table').DataTable({
        "processing": true,
        "serverSide": true,
        "ordering": false,
        "searching": false,
        "ajax": {
            "url": 'url',
            "type": "POST",
            "draw": 1,
            "data": function (data) {
                data.pageNumber = (data.start / data.length);
            },
            "dataFilter": function (data) {
                return JSON.stringify(data);
            },
            "dataSrc": function (data) {
                if (data.length > 0) {
                    data.recordsTotal = data[0].result_count;
                    data.recordsFiltered = data[0].result_count;
                    return data;
                }
                else
                    return "";
            },

            "error": function (xhr, error, thrown) {
                alert(thrown.message)
            }
        },
        columns: [
           { data: 'column_1' },
           { data: 'column_2' },
           { data: 'column_3' },
           { data: 'column_4' },
           { data: 'column_5' }
        ]
    });

Here is a simple example:

EXEC sp_executesql @sql, N'@p1 INT, @p2 INT, @p3 INT', @p1, @p2, @p3;

Your call will be something like this

EXEC sp_executesql @statement, N'@LabID int, @BeginDate date, @EndDate date, @RequestTypeID varchar', @LabID, @BeginDate, @EndDate, @RequestTypeID

Here is a way to do it without adding an ID to the form elements.

<form method="post">
    ...
    <select name="List">
        <option value="1">Test1</option>
        <option value="2">Test2</option>
    </select>
    <select name="List">
        <option value="3">Test3</option>
        <option value="4">Test4</option>
    </select>
    ...
</form>

public ActionResult OrderProcessor()
{
    string[] ids = Request.Form.GetValues("List");
}

Then ids will contain all the selected option values from the select lists. Also, you could go down the Model Binder route like so:

public class OrderModel
{
    public string[] List { get; set; }
}

public ActionResult OrderProcessor(OrderModel model)
{
    string[] ids = model.List;
}

Hope this helps.

There is also Mappa - http://mappatool.com/.

It only supports polygons, but they are definitely the hardest parts :)

You need to Add C:\Program Files\nodejs to your PATH environment variable. To do this follow these steps:

1. Use the global Search Charm to search "Environment Variables"
2. Click "Edit system environment variables"
3. Click "Environment Variables" in the dialog.
4. In the "System Variables" box, search for Path and edit it to include C:\Program Files\nodejs. Make sure it is separated from any other paths by a ;.

You will have to restart any currently-opened command prompts before it will take effect.

(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).

My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert() changed names to create() so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!

The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.

Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload class. This snippet assumes your auth code works where your service endpoint is DRIVE with a minimum auth scope of https://www.googleapis.com/auth/drive.file.

# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'

# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()
if rsp:
    print('Imported %r to %r (as %s)' % (SRC_FILENAME, DST_FILENAME, rsp['mimeType']))

Better yet, rather than uploading to My Drive, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.

If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.

Before you use DecimalFormat you need to use the following import or your code will not work:

import java.text.DecimalFormat;

The code for formatting is:

DecimalFormat precision = new DecimalFormat("0.00"); 
// dblVariable is a number variable and not a String in this case
txtTextField.setText(precision.format(dblVariable));

If I understand your question correctly, you can always just wrap the get function like so:

var $someJqueryEl = $($('.myJqueryEls').get(3));

It is likely something else, but for the future readers, check your date time format. i had a 14th month

Here is what works for me:

[1, "", 2, "hello", nil].reject(&:blank?)

output:

[1, 2, "hello"]

Along with the above answers , you can do this too

    =>  [*'1'.."5"]   #remember *
    => ["1", "2", "3", "4", "5"]

You can use

$objWorksheet->getActiveSheet()->getRowDimension('1')->setRowHeight(40);
$objWorksheet->getActiveSheet()->getColumnDimension('A')->setWidth(100);

or define auto-size:

$objWorksheet->getRowDimension('1')->setRowHeight(-1);

It's simple, whenever you see

 x->y

know it is the same as

 (*x).y

I think there is MID() and maybe LEFT() and RIGHT() in Access.

Here's another way to force a type-cast even between incompatible types and interfaces where TS compiler normally complains:

export function forceCast<T>(input: any): T {

  // ... do runtime checks here

  // @ts-ignore <-- forces TS compiler to compile this as-is
  return input;
}

Then you can use it to force cast objects to a certain type:

import { forceCast } from './forceCast';

const randomObject: any = {};
const typedObject = forceCast<IToDoDto>(randomObject);

Note that I left out the part you are supposed to do runtime checks before casting for the sake of reducing complexity. What I do in my project is compiling all my .d.ts interface files into JSON schemas and using ajv to validate in runtime.

You can solve that using display table.

Here is the updated JSFiddle that solves your problem.

CSS

.body {
    display: table;
    background-color: green;
}

.left-side {
    background-color: blue;
    float: none;
    display: table-cell;
    border: 1px solid;
}

.right-side {
    background-color: red;
    float: none;
    display: table-cell;
    border: 1px solid;
}

HTML

<div class="row body">
        <div class="col-xs-9 left-side">
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
            <p>sdfsdf</p>
        </div>
        <div class="col-xs-3 right-side">
            asdfdf
        </div>
    </div>

Alternatively you can use the views current layout parameters and modify them:

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) viewToLayout.getLayoutParams();
params.addRule(RelativeLayout.BELOW, R.id.below_id);

I solved the problem using Dmitry Komin solution, but with different CSS syntax to make it works directly in browser.

CSS

@media(min-width: 1400px){
    .my-modal > .modal-lg {
        width: 1308px;
    }
}

JS is the same:

var modal = $modal.open({
    animation: true,
    templateUrl: 'modalTemplate.html',
    controller: 'modalController',
    size: 'lg',
    windowClass: 'my-modal'
});

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

using JQuery:

myelement=$("#myelement")
[myelement.offset().left, myelement.offset().top,  myelement.width(), myelement.height()]

Figuring out what path to take requires answering not only CommonsWare's key question of "why" but also the question of "to what?" are you passing it.

The reality is that the only thing that can go through bundles is plain data - everything else is based on interpretations of what that data means or points to. You can't literally pass an object, but what you can do is one of three things:

1) You can break the object down to its constitute data, and if what's on the other end has knowledge of the same sort of object, it can assemble a clone from the serialized data. That's how most of the common types pass through bundles.

2) You can pass an opaque handle. If you are passing it within the same context (though one might ask why bother) that will be a handle you can invoke or dereference. But if you pass it through Binder to a different context it's literal value will be an arbitrary number (in fact, these arbitrary numbers count sequentially from startup). You can't do anything but keep track of it, until you pass it back to the original context which will cause Binder to transform it back into the original handle, making it useful again.

3) You can pass a magic handle, such as a file descriptor or reference to certain os/platform objects, and if you set the right flags Binder will create a clone pointing to the same resource for the recipient, which can actually be used on the other end. But this only works for a very few types of objects.

Most likely, you are either passing your class just so the other end can keep track of it and give it back to you later, or you are passing it to a context where a clone can be created from serialized constituent data... or else you are trying to do something that just isn't going to work and you need to rethink the whole approach.

Gmap writes inline style position to relative to the div. Overwrite that with :

google.maps.event.addListener(map, 'tilesloaded', function(){
    document.getElementById('maps').style.position = 'static';
    document.getElementById('maps').style.background = 'none';
});

Hope it helps.

You can always point to your home directory using ~ then you can refer to your data folder.

import pandas as pd
df = pd.read_csv("~/mydata/data.csv")

For your case, it should be like this

import pandas as pd
df = pd.read_csv("~/folder/folder2/data_folder/data.csv")

You can also set your data directory as a prefix

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
df = pd.read_csv(DATA_DIR+"data.csv")

You can take advantage of f-strings as @nikos-tavoularis said

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
FILE_NAME = "data.csv"
df = pd.read_csv(f"{DATA_DIR}{FILE_NAME}")

If you want to preserve the order of the element with the same length as the original array, use bubble sort.

Input = ["ab","cdc","abcd","de"];

Output  = ["ab","cd","cdc","abcd"]

Function:

function bubbleSort(strArray){
  const arrayLength = Object.keys(strArray).length;
    var swapp;
    var newLen = arrayLength-1;
    var sortedStrArrByLenght=strArray;
    do {
        swapp = false;
        for (var i=0; i < newLen; i++)
        {
            if (sortedStrArrByLenght[i].length > sortedStrArrByLenght[i+1].length)
            {
               var temp = sortedStrArrByLenght[i];
               sortedStrArrByLenght[i] = sortedStrArrByLenght[i+1];
               sortedStrArrByLenght[i+1] = temp;
               swapp = true;
            }
        }
        newLen--;
    } while (swap);
  return sortedStrArrByLenght;
}

Besides subprocess.call, you can also use subprocess.Popen. Like the following

subprocess.Popen(['./script', arg1, arg2])

I really like AVee's solution with the lowest IP connection metric! But if a second nic with the same metric is installed, the MAC comparison could fail...

Better you store the description of the interface with the MAC. In later comparisons you can identify the right nic by this string. Here is a sample code:

   public static string GetMacAndDescription()
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled=true");
        IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
        string mac = (from o in objects orderby o["IPConnectionMetric"] select o["MACAddress"].ToString()).FirstOrDefault();
        string description = (from o in objects orderby o["IPConnectionMetric"] select o["Description"].ToString()).FirstOrDefault();
        return mac + ";" + description;
    }

    public static string GetMacByDescription( string description)
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled=true");
        IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
        string mac = (from o in objects where o["Description"].ToString() == description select o["MACAddress"].ToString()).FirstOrDefault();
        return mac;
    }

Wanted to add my implementation of this as well. I apologize for all the missing semi-colons, this is written in Groovy.

I needed something more configurable than the accepted answer provided. Here's a rest template bean that's very agile and will log everything like the OP is looking for.

The simplest command by far:

npx http-server

This requires an existing index.html at the dir at where this command is being executed.

This was already mentioned by Vijaya Simha, but I thought using npx is way cleaner and shorter. I am running a webserver with this approach since months.

Docs: https://www.npmjs.com/package/http-server

Spring MVC will give you the HttpRequest if you just add it to your controller method signature:

For instance:

/**
 * Generate a PDF report...
 */
@RequestMapping(value = "/report/{objectId}", method = RequestMethod.GET)
public @ResponseBody void generateReport(
        @PathVariable("objectId") Long objectId, 
        HttpServletRequest request, 
        HttpServletResponse response) {

    // ...
    // Here you can use the request and response objects like:
    // response.setContentType("application/pdf");
    // response.getOutputStream().write(...);

}

As you see, simply adding the HttpServletRequest and HttpServletResponse objects to the signature makes Spring MVC to pass those objects to your controller method. You'll want the HttpSession object too.

EDIT: It seems that HttpServletRequest/Response are not working for some people under Spring 3. Try using Spring WebRequest/WebResponse objects as Eduardo Zola pointed out.

I strongly recommend you to have a look at the list of supported arguments that Spring MVC is able to auto-magically inject to your handler methods.

Try the following :

String url = "http://www.google.com/search?q=java";
URL urlObj = (URL)new URL(url.trim());
HttpURLConnection httpConn = 
(HttpURLConnection)urlObj.openConnection();
httpConn.setRequestMethod("GET");
Integer rescode = httpConn.getResponseCode();
System.out.println(rescode);

Trim() the URL

For anyone who lands here and all the other solutions did not work give this a try. I am using typescript + react and my problem was that I was associating the files in vscode as javascriptreact not typescriptreact so check your settings for the following entries.

   "files.associations": {
    "*.tsx": "typescriptreact",
    "*.ts": "typescriptreact"
  },

If you have your text in your_text variable, you can use:

your_text[0..29]

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms:number"]] 

This would be the best and short way to do it.

If you want to unit test code then you need to isolate your code you want to test (in this case your service) from external resources (e.g. databases). You could probably do this with some sort of in-memory EF provider, however a much more common way is to abstract away your EF implementation e.g. with some sort of repository pattern. Without this isolation any tests you write will be integration tests, not unit tests.

As for testing EF code - I write automated integration tests for my repositories that write various rows to the database during their initialization, and then call my repository implementations to make sure that they behave as expected (e.g. making sure that results are filtered correctly, or that they are sorted in the correct order).

These are integration tests not unit tests, as the tests rely on having a database connection present, and that the target database already has the latest up-to-date schema installed.

check the Command Prompt

ng --version OR ng version OR ng -v

I know this is an old thread, but there's another way that I've found useful for any extension.

Run

php -m | grep <module_name>

In this particular case:

php -m | grep memcache

If you want to list all PHP modules then:

php -m

Depending on your system you'd get an output similar to this:

[PHP Modules]
apc
bcmath
bz2
... lots of other modules ...
mbstring
memcache
 ... and still more modules ...
zip
zlib

[Zend Modules]

You can see that memcache is in this list.

Have you added the dll into your project references list? If not right click on the project "References" folder and selecet "Add Reference" then use browse to locate your science.dll, select it and click ok.

edit

I can't see the image of your VS instance that some people are referring to and I note that you now say that it works in Net4.0 and VS2010.

VS2008 projects support NET 3.5 by default. I expect that is the problem as your DLL may be NET 4.0 compliant but not NET 3.5.

You need to add the "global" flag to your regex:

s.replace(new RegExp("[0-9]", "g"), "X")

or, perhaps prettier, using the built-in literal regexp syntax:

.replace(/[0-9]/g, "X")

One pitfall with alloca is that longjmp rewinds it.

That is to say, if you save a context with setjmp, then alloca some memory, then longjmp to the context, you may lose the alloca memory. The stack pointer is back where it was and so the memory is no longer reserved; if you call a function or do another alloca, you will clobber the original alloca.

To clarify, what I'm specifically referring to here is a situation whereby longjmp does not return out of the function where the alloca took place! Rather, a function saves context with setjmp; then allocates memory with alloca and finally a longjmp takes place to that context. That function's alloca memory is not all freed; just all the memory that it allocated since the setjmp. Of course, I'm speaking about an observed behavior; no such requirement is documented of any alloca that I know.

The focus in the documentation is usually on the concept that alloca memory is associated with a function activation, not with any block; that multiple invocations of alloca just grab more stack memory which is all released when the function terminates. Not so; the memory is actually associated with the procedure context. When the context is restored with longjmp, so is the prior alloca state. It's a consequence of the stack pointer register itself being used for allocation, and also (necessarily) saved and restored in the jmp_buf.

Incidentally, this, if it works that way, provides a plausible mechanism for deliberately freeing memory that was allocated with alloca.

I have run into this as the root cause of a bug.

With version 3 of PowerShell you can chain the replace calls together:

 (Get-Content $sourceFile) | ForEach-Object {
    $_.replace('something1', 'something1').replace('somethingElse1', 'somethingElse2')
 } | Set-Content $destinationFile

It's not creating a file because you never actually created the file. You made an object for it. Creating an instance doesn't create the file.

File newFile = new File("directory", "fileName.txt");

You can do this to make a file:

newFile.createNewFile();

You can do this to make a folder:

newFile.mkdir();

You're passing link=$a and link=$b in the hrefs for A and B, respectively. They are treated as strings, not variables. The following should fix that for you:

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

// and

echo '<a href="pass.php?link=' . $b . '">Link 2</a>';

The value of $a also isn't included on pass.php. I would suggest making a common variable file and include it on all necessary pages.

You will need to handle your file access through web programming language, such as PHP or ASP.net.

To set this up, you would:

• Create a script that handles the file reading and writing. This should be visible to the browser.

• Send jQuery ajax requests to that script that either write data or read data. You would need to pass all of your read/write information through the request parameters. You can learn more about this in the jQuery ajax documentation.

Make sure that you sanitize any data that you are storing, since this could potentially be a security risk. However, this is really just standard flat-file data storage, and is not necessarily that unusual.

As Paolo pointed out, there is no way to directly read/write to a file through jQuery or any other type of javascript.

If you want to rotate a vector you should construct what is known as a rotation matrix.

Rotation in 2D

Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are

    x' = x cos ? - y sin ?
    y' = x sin ? + y cos ?

To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider

    Unit vector along X axis = <1, 0>
    x' = 1 cos 90 - 0 sin 90 = 0
    y' = 1 sin 90 + 0 cos 90 = 1
    New coordinates of the vector, <x', y'> = <0, 1>  ?  Y-axis

When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is

    |cos ?   -sin ?| |x| = |x cos ? - y sin ?| = |x'|
    |sin ?    cos ?| |y|   |x sin ? + y cos ?|   |y'|

Rotation in 3D

That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be

    |cos ?   -sin ?   0| |x|   |x cos ? - y sin ?|   |x'|
    |sin ?    cos ?   0| |y| = |x sin ? + y cos ?| = |y'|
    |  0       0      1| |z|   |        z        |   |z'|

around the Y-axis would be

    | cos ?    0   sin ?| |x|   | x cos ? + z sin ?|   |x'|
    |   0      1       0| |y| = |         y        | = |y'|
    |-sin ?    0   cos ?| |z|   |-x sin ? + z cos ?|   |z'|

around the X-axis would be

    |1     0           0| |x|   |        x        |   |x'|
    |0   cos ?    -sin ?| |y| = |y cos ? - z sin ?| = |y'|
    |0   sin ?     cos ?| |z|   |y sin ? + z cos ?|   |z'|

Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.

Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.

I hope this clarifies basic rotation.

Rotation not Revolution

The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.

Composition

I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).

Rotation around Arbitrary Vector

A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.

In Angular 7, the following simple example would work (assuming dictionary is in a variable called d):

my.component.ts:

keys: string[] = [];  // declaration of class member 'keys'
// component code ...

this.keys = Object.keys(d);

my.component.html: (will display list of key:value pairs)

<ul *ngFor="let key of keys">
    {{key}}: {{d[key]}}
</ul>

There are two ways to go about this. You can either use the IDE to generate a WSDL, or you can do it via the command line.

1. To create it via the IDE:

In the solution explorer pane, right click on the project that you would like to add the Service to:

Then, you can enter the path to your service WSDL and hit go:

2. To create it via the command line:

Open a VS 2010 Command Prompt (Programs -> Visual Studio 2010 -> Visual Studio Tools)
Then execute:

WSDL /verbose C:\path\to\wsdl

WSDL.exe will then output a .cs file for your consumption.

If you have other dependencies that you received with the file, such as xsd's, add those to the argument list:

WSDL /verbose C:\path\to\wsdl C:\path\to\some\xsd C:\path\to\some\xsd

If you need VB output, use /language:VB in addition to the /verbose.

There is nothing to fix. You simply have made 3 commits and haven't moved them to the remote branch yet. There are several options, depending on what you want to do:

• git push: move your changes to the remote (this might get rejected if there are already other changes on the remote)
• do nothing and keep coding, sync another day
• git pull: get the changes (if any) from the remote and merge them into your changes
• git pull --rebase: as above, but try to redo your commits on top of the remote changes

You are in a classical situation (although usually you wouldn't commit a lot on master in most workflows). Here is what I would normally do: Review my changes. Maybe do a git rebase --interactive to do some cosmetics on them, drop the ones that suck, reorder them to make them more logical. Now move them to the remote with git push. If this gets rejected because my local branch is not up to date: git pull --rebase to redo my work on top of the most recent changes and git push again.

Better solution

var checkfloats = function(event){
    var charCode = (event.which) ? event.which : event.keyCode;
    if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57))
        return false;

    if(event.target.value.indexOf('.') >=0 && charCode == 46)
        return false;

    return true;
}

Very useful, especially for those dealing with Node.js where we want to avoid searching inside "node_modules":

find ./ -not -path "*/node_modules/*" -name "*.js" | xargs grep keyword

You can index and use a negative sign to drop the 3rd column:

data[,-3]

Or you can list only the first 2 columns:

data[,c("c1", "c2")]
data[,1:2]

Don't forget the comma and referencing data frames works like this: data[row,column]

Generally if you are not sure of what value you will end up returning, you should consider using return-type as super-class of all the return values. In this case, where you need to return String or int, consider returning Object class(which is the base class of all the classes defined in java).

But be careful to have instanceof checks where you are calling this method. Or else you may end up getting ClassCastException.

public static void main(String args[]) {
        Object obj = myMethod(); // i am calling static method from main() which return Object
    if(obj instanceof String){
    // Do something
    }else(obj instance of Integer) {
    //do something else
     }

I usually construct custom objects in these loops, and then add these objects to an array that I can easily manipulate, sort, export to CSV, etc.:

# Construct an out-array to use for data export
$OutArray = @()

# The computer loop you already have
foreach ($server in $serverlist)
    {
        # Construct an object
        $myobj = "" | Select "computer", "Speed", "Regcheck"

        # Fill the object
        $myobj.computer = $computer
        $myobj.speed = $speed
        $myobj.regcheck = $regcheck

        # Add the object to the out-array
        $outarray += $myobj

        # Wipe the object just to be sure
        $myobj = $null
    }

# After the loop, export the array to CSV
$outarray | export-csv "somefile.csv"

Yeah, for most cases, you don't need to create a class with getters and setters. Just create a new Dictionary and bind it to the data source. Here's an example in VB using a for loop to set the DisplayMember and ValueMember of a combo box from a list:

        Dim comboSource As New Dictionary(Of String, String)()
        cboMenu.Items.Clear()
        For I = 0 To SomeList.GetUpperBound(0)
            comboSource.Add(SomeList(I).Prop1, SomeList(I).Prop2)
        Next I
        cboMenu.DataSource = New BindingSource(comboSource, Nothing)
        cboMenu.DisplayMember = "Value"
        cboMenu.ValueMember = "Key"

Then you can set up a data grid view's rows according to the value or whatever you need by calling a method on click:

Private Sub cboMenu_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cboMenu.SelectionChangeCommitted
    SetListGrid(cboManufMenu.SelectedValue)
End Sub

Well, of course, this doesn't apply to all projects. Still, QCoreApplication::applicationFilePath() never failed me in 6 years of C++/Qt development.

Of course, one should read documentation thoroughly before attempting to use it:

Warning: On Linux, this function will try to get the path from the /proc file system. If that fails, it assumes that argv[0] contains the absolute file name of the executable. The function also assumes that the current directory has not been changed by the application.

To be honest, I think that #ifdef and other solutions like that shouldn't be used in modern code at all.

I'm sure that smaller cross-platform libraries also exist. Let them encapsulate all that platform-specific stuff inside.

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

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

Use like this

<div ng-if="data.IsActive === 1">InActive</div>
<div ng-if="data.IsActive === 0">Active</div>

Yes, you can do ajax request to server with your data in request parameters, like this (very simple):

Note that the following code uses jQuery

jQuery.ajax({
    type: "POST",
    url: 'your_functions_address.php',
    dataType: 'json',
    data: {functionname: 'add', arguments: [1, 2]},

    success: function (obj, textstatus) {
                  if( !('error' in obj) ) {
                      yourVariable = obj.result;
                  }
                  else {
                      console.log(obj.error);
                  }
            }
});

and your_functions_address.php like this:

    <?php
    header('Content-Type: application/json');

    $aResult = array();

    if( !isset($_POST['functionname']) ) { $aResult['error'] = 'No function name!'; }

    if( !isset($_POST['arguments']) ) { $aResult['error'] = 'No function arguments!'; }

    if( !isset($aResult['error']) ) {

        switch($_POST['functionname']) {
            case 'add':
               if( !is_array($_POST['arguments']) || (count($_POST['arguments']) < 2) ) {
                   $aResult['error'] = 'Error in arguments!';
               }
               else {
                   $aResult['result'] = add(floatval($_POST['arguments'][0]), floatval($_POST['arguments'][1]));
               }
               break;

            default:
               $aResult['error'] = 'Not found function '.$_POST['functionname'].'!';
               break;
        }

    }

    echo json_encode($aResult);

?>

GregorianCalendar date;

CharSequence dateForMart = android.text.format.DateFormat.format("yyyy-MM-dd", date);

Toast.makeText(LogmeanActivity.this,dateForMart,Toast.LENGTH_LONG).show();

You have install nodeJs on your system in order to execute npm commands. Once npm is properly working you can visit bower.io. There you will find complete documentation on this topic. You will find a command $ npm install bower. this will install bower on your machine. After installing bower you can install Bootstrap easily.

Here is a video tutorial on that

I had to reinstall .NET desktop development (throught Workload tab), even button was showing: Modify

After that Visual C# selection appeared :) (And now i can use Console APP Template)

For Unicode support:

public class HexadecimalEncoding
{
    public static string ToHexString(string str)
    {
        var sb = new StringBuilder();

        var bytes = Encoding.Unicode.GetBytes(str);
        foreach (var t in bytes)
        {
            sb.Append(t.ToString("X2"));
        }

        return sb.ToString(); // returns: "48656C6C6F20776F726C64" for "Hello world"
    }

    public static string FromHexString(string hexString)
    {
        var bytes = new byte[hexString.Length / 2];
        for (var i = 0; i < bytes.Length; i++)
        {
            bytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
        }

        return Encoding.Unicode.GetString(bytes); // returns: "Hello world" for "48656C6C6F20776F726C64"
    }
}

You seem to misunderstand the box model - in CSS you provide points for the top and left and then width and height - these are all that are needed for a box to be placed with exact measurements.

The width property is what your C-D is, but it is also what A-B is. If you omit it, the div will not have a defined width and the width will be defined by its contents.

Update (following the comments on the question:

Add a border-bottom-style: none; to your CSS to remove this style from the bottom only.

Use case:

 sesssionStorage.setObj(1,{date:Date.now(),action:'save firstObject'});
 sesssionStorage.setObj(2,{date:Date.now(),action:'save 2nd object'}); 
 //Query first object
  sesssionStorage.getObj(1)
  //Retrieve date created of 2nd object
  new Date(sesssionStorage.getObj(1).date)

API

Storage.prototype.setObj = function(key, obj) {

        return this.setItem(key, JSON.stringify(obj))
    };
    
    Storage.prototype.getObj = function(key) {
        return JSON.parse(this.getItem(key))
    };

Yes, it's OK - it's just like using it in an if statement. Of course, you can't use a break to break out of a loop from inside a switch.

I think the even shorter answer that you'll like is: StringUtils.isBlank(acct);

From the documentation: http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringUtils.html#isBlank%28java.lang.String%29

isBlank
public static boolean isBlank(String str)
Checks if a String is whitespace, empty ("") or null.

 StringUtils.isBlank(null)      = true
 StringUtils.isBlank("")        = true
 StringUtils.isBlank(" ")       = true
 StringUtils.isBlank("bob")     = false
 StringUtils.isBlank("  bob  ") = false
 
Parameters:
str - the String to check, may be null
Returns:
true if the String is null, empty or whitespace

This is how I did it. This makes the images in the slideshow take up the full screen if it´s aspect ratio allows it, othervice it scales down.

.carousel {
    height: 100vh;
    width: 100%;
    overflow:hidden;
}
.carousel .carousel-inner {
    height:100%;    
}

To allways get a full screen slideshow, no matter screen aspect ratio, you can also use object-fit: (doesn´t work in IE or Edge)

.carousel .carousel-inner img {
    display:block;
    object-fit: cover;
}

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

Use android:weightSum property to the parent LinearLayout and give value 3. Then in the children LinearLayout use android:layout_weight 2 and 1 respectively. Then in the First Chil LinearLayout use android:layout_gravity="center_vertical". As shown in the following code

<LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:weightSum="3"
                    android:orientation="horizontal">

                    <LinearLayout

                            android:textSize="@dimen/default_text_size"
                            />
                    </LinearLayout>
                    <LinearLayout
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_weight="1">
                        <Button
                          android:layout_width="fill_parent"
                          android:layout_height="wrap_content"
                          android:text="Delete"/>
                    </LinearLayout>
                </LinearLayout>

Here's a quick way to do it, won't require anything besides sys.. though functionality is limited:

flag = "--flag" in sys.argv[1:]

[1:] is in case if the full file name is --flag

I found the tutorial Working with UIGestureRecognizers, and I think that is what I am looking for. It helped me come up with the following solution:

-(IBAction) someMethod {
    UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)];
    [panRecognizer setMinimumNumberOfTouches:1];
    [panRecognizer setMaximumNumberOfTouches:1];
    [ViewMain addGestureRecognizer:panRecognizer];
    [panRecognizer release];
}

-(void)move:(UIPanGestureRecognizer*)sender {
    [self.view bringSubviewToFront:sender.view];

I made my own subversion repository on my Ubuntu One folder. Then, I imported the files to the repository using svn+ssh and my user account password.

When I want to do a checkout, I just checkout from my Ubuntu One folder. The commit process its analogue.

You must setup Ubutnu One on the devices that you want to grant access, then checkout the project from this folder to a temporary folder to edit it.

In my case, I use a folder in the Ubuntu One file-system, so I have the repository and my develop-folder in Ubuntu One.

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

You can use for loop to find your element and update it:

updateItem(newItem){
  for (let i = 0; i < this.itemsArray.length; i++) {
      if(this.itemsArray[i].id == newItem.id){
        this.users[i] = newItem;
      }
    }
}

Very simply:

Arrays.asList("Hi!")

No one has answered the question: Why is this concept confusing?

As an undergrad Computer Science major it took me awhile to understand this because of the way I read the code.

The following is not correct!

x = y++

X is equal to y post increment. Which would logically seem to mean X is equal to the value of Y after the increment operation is done. Post meaning after.

or

x = ++y
X is equal to y pre-increment. Which would logically seem to mean X is equal to the value of Y before the increment operation is done. Pre meaning before.

The way it works is actually the opposite. This concept is confusing because the language is misleading. In this case we cannot use the words to define the behavior.
x=++y is actually read as X is equal to the value of Y after the increment.
x=y++ is actually read as X is equal to the value of Y before the increment.

The words pre and post are backwards with respect to semantics of English. They only mean where the ++ is in relation Y. Nothing more.

Personally, if I had the choice I would switch the meanings of ++y and y++. This is just an example of a idiom that I had to learn.

If there is a method to this madness I'd like to know in simple terms.

Thanks for reading.

IList<string> list = new List<string> {"test1", "test2", "test3"}

I've made a simple function for this.

The _case function allows you to not only get the target, but also get the parent element where you bind the event on.

The callback function returns the event which holds the target (evt.target) and the parent element matching the selector (this). Here you can do the stuff you need after the element is clicked.

I've not yet decided which is better, the if-else or the switch

var _case = function(evt, selector, cb) {_x000D_
  var _this = evt.target.closest(selector);_x000D_
  if (_this && _this.nodeType) {_x000D_
    cb.call(_this, evt);_x000D_
    return true;_x000D_
  } else { return false; }_x000D_
}_x000D_
_x000D_
document.getElementById('ifelse').addEventListener('click', function(evt) {_x000D_
  if (_case(evt, '.parent1', function(evt) {_x000D_
      console.log('1: ', this, evt.target);_x000D_
    })) return false;_x000D_
_x000D_
  if (_case(evt, '.parent2', function(evt) {_x000D_
      console.log('2: ', this, evt.target);_x000D_
    })) return false;_x000D_
_x000D_
  console.log('ifelse: ', this);_x000D_
})_x000D_
_x000D_
_x000D_
document.getElementById('switch').addEventListener('click', function(evt) {_x000D_
  switch (true) {_x000D_
    case _case(evt, '.parent3', function(evt) {_x000D_
      console.log('3: ', this, evt.target);_x000D_
    }): break;_x000D_
    case _case(evt, '.parent4', function(evt) {_x000D_
      console.log('4: ', this, evt.target);_x000D_

Yes, a GUID should always be unique. It is based on both hardware and time, plus a few extra bits to make sure it's unique. I'm sure it's theoretically possible to end up with two identical ones, but extremely unlikely in a real-world scenario.

Here's a great article by Raymond Chen on Guids:

https://blogs.msdn.com/oldnewthing/archive/2008/06/27/8659071.aspx ? ? ?

I was almost using the same technology as you did, however I was using my app to connect an Exchange Server via Office 365 platform on WinForms. I too had the same issue as you did, but was able to accomplish by using code which has slight modification of what others have given above.

SmtpClient client = new SmtpClient(exchangeServer, 587);
client.Credentials = new System.Net.NetworkCredential(username, password);
client.EnableSsl = true;
client.Send(msg);

I had to use the Port 587, which is of course the default port over TSL and the did the authentication.

          @{  var result = string.Join(",", @user.UserRoles.Select(x => x.Role.RoleName));
              @result

           }

I used in MVC Razor View to evaluate and print all roles separated by commas.

Then number of columns must match between both parts of the union.

In order to build the full path, you need to "aggregate" all values of the Location column. You still need to select the id and other columns inside the CTE in order to be able to join properly. You get "rid" of them by simply not selecting them in the outer select:

with q as 
(
   select ID, PartOf_LOC_id, Location, ' > ' + Location as path
   from tblLocation 
   where ID = 1 

   union all

   select child.ID, child.PartOf_LOC_id, Location, parent.path + ' > ' + child.Location 
   from tblLocation child
     join q parent on parent.ID = t.LOC_PartOf_ID
)
select path
from q;

If you have the product's ID you can use that to create a product object:

$_product = wc_get_product( $product_id );

Then from the object you can run any of WooCommerce's product methods.

$_product->get_regular_price();
$_product->get_sale_price();
$_product->get_price();

Update
Please review the Codex article on how to write your own shortcode.

Integrating the WooCommerce product data might look something like this:

function so_30165014_price_shortcode_callback( $atts ) {
    $atts = shortcode_atts( array(
        'id' => null,
    ), $atts, 'bartag' );

    $html = '';

    if( intval( $atts['id'] ) > 0 && function_exists( 'wc_get_product' ) ){
         $_product = wc_get_product( $atts['id'] );
         $html = "price = " . $_product->get_price();
    }
    return $html;
}
add_shortcode( 'woocommerce_price', 'so_30165014_price_shortcode_callback' );

Your shortcode would then look like [woocommerce_price id="99"]

You could define a mapping of air pressure to servo angle, for example:

def calc_angle(pressure, min_p=1000, max_p=1200):     return 360 * ((pressure - min_p) / float(max_p - min_p))  angle = calc_angle(pressure) 

This will linearly convert pressure values between min_p and max_p to angles between 0 and 360 (you could include min_a and max_a to constrain the angle, too).

To pick a data structure, I wouldn't use a list but you could look up values in a dictionary:

d = {1000:0, 1001: 1.8, ...}  angle = d[pressure] 

but this would be rather time-consuming to type out!

I don't think there is a way to tell which program to use from just the .db extension. It could even be an encrypted database which can't be opened. You can MS Access, or a sqlite manager.

Edit: Try to rename the file to .txt and open it with a text editor. The first couple of words in the file could tell you the DB Type.

If it is a SQLite database, it will start with "SQLite format 3"

In your html

<table class="table1">
<tr>
<td>
...
</table>

<table class="table2">

<tr>
<td>
...
</table>

In your css:

table.table1 {...}
table.table1 tr {...}
table.table1 td {...}

table.table2 {...}
table.table2 tr {...}
table.table2 td {...}

The HttpWebRequest modifies the CookieContainer assigned to it. There is no need to process returned cookies. Simply assign your cookie container to every web request.

public class CookieAwareWebClient : WebClient
{
    public CookieContainer CookieContainer { get; set; } = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri uri)
    {
        WebRequest request = base.GetWebRequest(uri);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = CookieContainer;
        }
        return request;
    }
}

Yes it is possible.

You need to use the getDeclaredField method (instead of the getField method), with the name of your private field:

Field privateField = Test.class.getDeclaredField("str");

Additionally, you need to set this Field to be accessible, if you want to access a private field:

privateField.setAccessible(true);

Once that's done, you can use the get method on the Field instance, to access the value of the str field.

As long as you are using CREATE TABLE, if you are creating the primary key on a single field, you can use:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER PRIMARY KEY,
field3 BLOB,
);

With CREATE TABLE, you can also always use the following approach to create a primary key on one or multiple fields:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER,
field3 BLOB,
PRIMARY KEY (field2, field1)
);

This answer does not address table alteration.

I found that the following worked for me - instead on using on click, use on change e.g.:

 jQuery('#element select').on('change',  (function() {

       //your code here

}));

I use this JS snippet code :

First of all, I reach all the classes then according to index of my target class, I set className = "".

Target = document.getElementsByClassName("yourClass")[1];
Target.className="";

If you add -chain to your command line, it will export any chained certificates.

http://www.openssl.org/docs/apps/pkcs12.html

to just look at a tables layout from the cli. you would do

desc mytable

or

show table mytable

I had a similar issue when deploying from OSx on my local to my Linux live site.

It ran fine on OSx, but on Linux I was getting:

An Error Was Encountered

Unable to load the requested class: Ckeditor

The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".

I also changed my load call to match the capitalization:

$this->load->library('CKEditor');

If you're using C# ASP.NET MVC's default template you may find that site.css overrides some of Bootstraps styles. If you want to use Bootstrap, as I did, having M$ override this (without your knowledge) can be a source of great frustration! Feel free to remove any of the unwanted styles...

/* Set width on the form input elements since they're 100% wide by default */
input,
select,
textarea {
    max-width: 280px;
}

I can tell you another simple way to fix the width of data table in html itself.

use

<colgroup>
    <col width="3%">
    <col width="3%">
</colgroup>

here is a sample code of data table below:

         <table class="table datatable">
                                <colgroup>
                                    <col width="33%">
                                    <col width="33%">
                                    <col width="33%">
                                    <col width="33%">
                                </colgroup>
                                   <thead>
                                        <tr>

                                        </tr>
                                    </thead>
                                        <tr>

                                            <th>delta</th>
                                        </tr>
                                        <tr>

                            </table>

To compare two objects you can use:

angular.equals(obj1, obj2)

It does a deep comparison and does not depend on the order of the keys See AngularJS DOCS and a little Demo

var obj1 = {
  key1: "value1",
  key2: "value2",
  key3: {a: "aa", b: "bb"}
}

var obj2 = {
  key2: "value2",
  key1: "value1",
  key3: {a: "aa", b: "bb"}
}

angular.equals(obj1, obj2) //<--- would return true

Are you ssh'ing to a directory that's inside your work tree? If the root of your ssh mount point doesn't include the .git dir, then zsh won't be able to find git info. Make sure you're mounting something that includes the root of the repo.

As for GIT_DISCOVERY_ACROSS_FILESYSTEM, it doesn't do what you want. Git by default will stop at a filesystem boundary. If you turn that on (and it's just an env var), then git will cross the filesystem boundary and keep looking. However, that's almost never useful, because you'd be implying that you have a .git directory on your local machine that's somehow meant to manage a work tree that's comprised partially of an sshfs mount. That doesn't make much sense.

Right from the docs:

-fpermissive
Downgrade some diagnostics about nonconformant code from errors to warnings. Thus, using -fpermissive will allow some nonconforming code to compile.

Bottom line: don't use it unless you know what you are doing!

I'd use JSON as the format and Ajax (really XMLHttpRequest) as the client->server mechanism.

There are many appropiate solution to this problem as mentioned above in this post, but i have found a small hack that can be inserrted in the script or pasted in the Chromes console (debugger) to achieve it:

jQuery(window).keydown(function(e) { if (e.keyCode == 123) debugger; });

This will cause execution to be paused when you hit F12.

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.

First difference - Fail Fast

I agree with @zzzzBov's answer, but the "fail fast" advantage of Promise.all is not the only difference. Some users in the comments have asked why using Promise.all is worth it when it's only faster in the negative scenario (when some task fails). And I ask, why not? If I have two independent async parallel tasks and the first one takes a very long time to resolve but the second is rejected in a very short time, why leave the user to wait for the longer call to finish to receive an error message? In real-life applications we must consider the negative scenario. But OK - in this first difference you can decide which alternative to use: Promise.all vs. multiple await.

Second difference - Error Handling

But when considering error handling, YOU MUST use Promise.all. It is not possible to correctly handle errors of async parallel tasks triggered with multiple awaits. In the negative scenario you will always end with UnhandledPromiseRejectionWarning and PromiseRejectionHandledWarning, regardless of where you use try/ catch. That is why Promise.all was designed. Of course someone could say that we can suppress those errors using process.on('unhandledRejection', err => {}) and process.on('rejectionHandled', err => {}) but this is not good practice. I've found many examples on the internet that do not consider error handling for two or more independent async parallel tasks at all, or consider it but in the wrong way - just using try/ catch and hoping it will catch errors. It's almost impossible to find good practice in this.

Summary

TL;DR: Never use multiple await for two or more independent async parallel tasks, because you will not be able to handle errors correctly. Always use Promise.all() for this use case.

Async/ await is not a replacement for Promises, it's just a pretty way to use promises. Async code is written in "sync style" and we can avoid multiple thens in promises.

Some people say that when using Promise.all() we can't handle task errors separately, and that we can only handle the error from the first rejected promise (separate handling can be useful e.g. for logging). This is not a problem - see "Addition" heading at the bottom of this answer.

Examples

Consider this async task...

const task = function(taskNum, seconds, negativeScenario) {
  return new Promise((resolve, reject) => {
    setTimeout(_ => {
      if (negativeScenario)
        reject(new Error('Task ' + taskNum + ' failed!'));
      else
        resolve('Task ' + taskNum + ' succeed!');
    }, seconds * 1000)
  });
};

When you run tasks in the positive scenario there is no difference between Promise.all and multiple awaits. Both examples end with Task 1 succeed! Task 2 succeed! after 5 seconds.

// Promise.all alternative
const run = async function() {
  // tasks run immediate in parallel and wait for both results
  let [r1, r2] = await Promise.all([
    task(1, 5, false),
    task(2, 5, false)
  ]);
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: Task 1 succeed! Task 2 succeed!

// multiple await alternative
const run = async function() {
  // tasks run immediate in parallel
  let t1 = task(1, 5, false);
  let t2 = task(2, 5, false);
  // wait for both results
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: Task 1 succeed! Task 2 succeed!

However, when the first task takes 10 seconds and succeeds, and the second task takes 5 seconds but fails, there are differences in the errors issued.

// Promise.all alternative
const run = async function() {
  let [r1, r2] = await Promise.all([
      task(1, 10, false),
      task(2, 5, true)
  ]);
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!

// multiple await alternative
const run = async function() {
  let t1 = task(1, 10, false);
  let t2 = task(2, 5, true);
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)
// at 10th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!

We should already notice here that we are doing something wrong when using multiple awaits in parallel. Let's try handling the errors:

// Promise.all alternative
const run = async function() {
  let [r1, r2] = await Promise.all([
    task(1, 10, false),
    task(2, 5, true)
  ]);
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Caught error', err); });
// at 5th sec: Caught error Error: Task 2 failed!

As you can see, to successfully handle errors, we need to add just one catch to the run function and add code with catch logic into the callback. We do not need to handle errors inside the run function because async functions do this automatically - promise rejection of the task function causes rejection of the run function.

To avoid a callback we can use "sync style" (async/ await + try/ catch)
try { await run(); } catch(err) { }
but in this example it's not possible, because we can't use await in the main thread - it can only be used in async functions (because nobody wants to block main thread). To test if handling works in "sync style" we can call the run function from another async function or use an IIFE (Immediately Invoked Function Expression: MDN):

(async function() { 
  try { 
    await run(); 
  } catch(err) { 
    console.log('Caught error', err); 
  }
})();

This is the only correct way to run two or more async parallel tasks and handle errors. You should avoid the examples below.

Bad Examples

// multiple await alternative
const run = async function() {
  let t1 = task(1, 10, false);
  let t2 = task(2, 5, true);
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};

We can try to handle errors in the code above in several ways...

try { run(); } catch(err) { console.log('Caught error', err); };
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled 

... nothing got caught because it handles sync code but run is async.

run().catch(err => { console.log('Caught error', err); });
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: Caught error Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... huh? We see firstly that the error for task 2 was not handled and later that it was caught. Misleading and still full of errors in console, it's still unusable this way.

(async function() { try { await run(); } catch(err) { console.log('Caught error', err); }; })();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: Caught error Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... the same as above. User @Qwerty in his deleted answer asked about this strange behavior where an error seems to be caught but are also unhandled. We catch error the because run() is rejected on the line with the await keyword and can be caught using try/ catch when calling run(). We also get an unhandled error because we are calling an async task function synchronously (without the await keyword), and this task runs and fails outside the run() function.
It is similar to when we are not able to handle errors by try/ catch when calling some sync function which calls setTimeout:

function test() {
  setTimeout(function() { 
    console.log(causesError); 
    }, 0);
}; 
try { 
  test(); 
} catch(e) { 
  /* this will never catch error */ 
}`.

Another poor example:

const run = async function() {
  try {
    let t1 = task(1, 10, false);
    let t2 = task(2, 5, true);
    let r1 = await t1;
    let r2 = await t2;
  }
  catch (err) {
    return new Error(err);
  }
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Caught error', err); });
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... "only" two errors (3rd one is missing) but nothing is caught.

Addition (handling separate task errors and also first-fail error)

const run = async function() {
  let [r1, r2] = await Promise.all([
    task(1, 10, true).catch(err => { console.log('Task 1 failed!'); throw err; }),
    task(2, 5, true).catch(err => { console.log('Task 2 failed!'); throw err; })
  ]);
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Run failed (does not matter which task)!'); });
// at 5th sec: Task 2 failed!
// at 5th sec: Run failed (does not matter which task)!
// at 10th sec: Task 1 failed!

... note that in this example I rejected both tasks to better demonstrate what happens (throw err is used to fire final error).

Here is the little hack to overcome all the struggles you have for video autoplay in a website:

1. Check video is playing or not.
2. Trigger video play on event like body click or touch.

Note: Some browsers don't let videos to autoplay unless the user interacts with the device.

So scripts to check whether video is playing is:

Object.defineProperty(HTMLMediaElement.prototype, 'playing', {
get: function () {
    return !!(this.currentTime > 0 && !this.paused && !this.ended && this.readyState > 2);
}});

And then you can simply autoplay the video by attaching event listeners to the body:

$('body').on('click touchstart', function () {
        const videoElement = document.getElementById('home_video');
        if (videoElement.playing) {
            // video is already playing so do nothing
        }
        else {
            // video is not playing
            // so play video now
            videoElement.play();
        }
});

Note: autoplay attribute is very basic which needs to be added to the video tag already other than these scripts.

You can see the working example with code here at this link:

How to autoplay video when the device is in low power mode / data saving mode / safari browser issue

You can imitate open source Dockerfile, for example:

Node: node12-github

RUN groupadd --gid 1000 node \
    && useradd --uid 1000 --gid node --shell /bin/bash --create-home node

superset: superset-github

RUN useradd --user-group --create-home --no-log-init --shell /bin/bash 
    superset

I think it's a good way to follow open source.

INFORMATION_SCHEMA is your friend. It has all kinds of views that show all kinds of schema information. Check your system views. You will find you have three views dealing with constraints, one being CHECK_CONSTRAINTS.

I have faced this issue many times. This usually comes when you delete your build folder.

The easy solution is to de-integrate and install the pod files again.

pod deintegrate
pod install

There is definitly a problem with the destination folder path.

Your above error message says, it wants to put the contents to a file in the directory /files/grantapps/, which would be beyond your vhost, but somewhere in the system (see the leading absolute slash )

You should double check:

• Is the directory /home/username/public_html/files/grantapps/ really present.
• Contains your loop and your file_put_contents-Statement the absolute path /home/username/public_html/files/grantapps/

I just had to do this... so maybe late to the party - but someone may find it useful

def str_to_bool(input, default):
    """
    | Default | not_default_str | input   | result
    | T       |  "false"        | "true"  |  T
    | T       |  "false"        | "false" |  F
    | F       |  "true"         | "true"  |  T
    | F       |  "true"         | "false" |  F

    """
    if default:
        not_default_str = "false"
    else:
        not_default_str = "true"

    if input.lower() == not_default_str:
        return not default
    else:
        return default

For the best practice - use style="display:"

it will work every where..

The solution is to set the default value in your .elem. But this annimation work fine with -moz but not yet implement in -webkit

Look at the fiddle I updated from yours : http://jsfiddle.net/DoubleYo/4Vz63/1648/

It works fine with Firefox but not with Chrome

When something in the state has changed and you need to call a side effect (like a request to api - get, put, post, delete). So you need to call componentDidUpdate() because componentDidMount() is already called.

After calling side effect in componentDidUpdate(), you can set the state to new value based on the response data in the then((response) => this.setState({newValue: "here"})). Please make sure that you need to check prevProps or prevState to avoid infinite loop because when setting state to a new value, the componentDidUpdate() will call again.

There are 2 places to call a side effect for best practice - componentDidMount() and componentDidUpdate()

CURL in PHP:

Summary:

The curl_exec command in PHP is a bridge to use curl from console. curl_exec makes it easy to quickly and easily do GET/POST requests, receive responses from other servers like JSON and download files.

Warning, Danger:

curl is evil and dangerous if used improperly because it is all about getting data from out there in the internet. Someone can get between your curl and the other server and inject a rm -rf / into your response, and then why am I dropped to a console and ls -l doesn't even work anymore? Because you mis underestimated the dangerous power of curl. Don't trust anything that comes back from curl to be safe, even if you are talking to your own servers. You could be pulling back malware to relieve fools of their wealth.

Examples:

These were done on Ubuntu 12.10

1. Basic curl from the commandline:

   el@apollo:/home/el$ curl http://i.imgur.com/4rBHtSm.gif > mycat.gif
     % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                    Dload  Upload   Total   Spent    Left  Speed
   100  492k  100  492k    0     0  1077k      0 --:--:-- --:--:-- --:--:-- 1240k
   

   Then you can open up your gif in firefox:

   firefox mycat.gif
   

   Glorious cats evolving Toxoplasma gondii to cause women to keep cats around and men likewise to keep the women around.

2. cURL example get request to hit google.com, echo to the commandline:

   This is done through the phpsh terminal:

   php> $ch = curl_init();
   
   php> curl_setopt($ch, CURLOPT_URL, 'http://www.google.com');
   
   php> curl_exec($ch);
   

   Which prints and dumps a mess of condensed html and javascript (from google) to the console.

3. cURL example put the response text into a variable:

   This is done through the phpsh terminal:

   php> $ch = curl_init();
   
   php> curl_setopt($ch, CURLOPT_URL, 'http://i.imgur.com/wtQ6yZR.gif');
   
   php> curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
   php> $contents = curl_exec($ch);
   
   php> echo $contents;
   

   The variable now contains the binary which is an animated gif of a cat, possibilities are infinite.

4. Do a curl from within a PHP file:

   Put this code in a file called myphp.php:

   <?php
     $curl_handle=curl_init();
     curl_setopt($curl_handle,CURLOPT_URL,'http://www.google.com');
     curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
     curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
     $buffer = curl_exec($curl_handle);
     curl_close($curl_handle);
     if (empty($buffer)){
         print "Nothing returned from url.<p>";
     }
     else{
         print $buffer;
     }
   ?>
   

   Then run it via commandline:

   php < myphp.php
   

   You ran myphp.php and executed those commands through the php interpreter and dumped a ton of messy html and javascript to screen.

   You can do GET and POST requests with curl, all you do is specify the parameters as defined here: Using curl to automate HTTP jobs

Reminder of danger:

Be careful dumping curl output around, if any of it gets interpreted and executed, your box is owned and your credit card info will be sold to third parties and you'll get a mysterious $900 charge from an Alabama one-man flooring company that's a front for overseas credit card fraud crime ring.

new Guid() makes an "empty" all-0 guid (00000000-0000-0000-0000-000000000000 is not very useful).

Guid.NewGuid() makes an actual guid with a unique value, what you probably want.

The problem with VBA is that there are both dynamic and static arrays...

Dynamic Array Example

Dim myDynamicArray() as Variant

Static Array Example

Dim myStaticArray(10) as Variant
Dim myOtherStaticArray(0 To 10) as Variant

Using error handling to check if the array is empty works for a Dynamic Array, but a static array is by definition not empty, there are entries in the array, even if all those entries are empty.

So for clarity's sake, I named my function "IsZeroLengthArray".

    Public Function IsZeroLengthArray(ByRef subject() As Variant) As Boolean
        'Tell VBA to proceed if there is an error to the next line.
        On Error Resume Next
    
        Dim UpperBound As Integer
        Dim ErrorNumber As Long
        Dim ErrorDescription As String
        Dim ErrorSource As String
    
        'If the array is empty this will throw an error because a zero-length 
          'array has no UpperBound (or LowerBound).
        'This only works for dynamic arrays.  If this was a static array there 
          'would be both an upper and lower bound.
        UpperBound = UBound(subject)


        'Store the Error Number and then clear the Error object 
         'because we want VBA to treat unintended errors normally
        ErrorNumber = Err.Number
        ErrorDescription = Err.Description
        ErrorSource = Err.Source
        Err.Clear
        On Error GoTo 0
    
        'Check the Error Object to see if we have a "subscript out of range" error.  
          'If we do (the number is 9) then we can assume that the array is zero-length.
        If ErrorNumber = 9 Then
            IsZeroLengthArray = True

        'If the Error number is something else then 9 we want to raise 
        'that error again...
        ElseIf ErrorNumber <> 0 Then
            Err.Raise ErrorNumber, ErrorSource, ErrorDescription

        'If the Error number is 0 then we have no error and can assume that the
         'array is not of zero-length
        ElseIf ErrorNumber = 0 Then
            IsZeroLengthArray = False
        End If
    End Function

I hope that this helps others as it helped me.

I tested the performance of FileInputStream vs. FileChannel for decoding base64 encoded files. In my experients I tested rather large file and traditional io was alway a bit faster than nio.

FileChannel might have had an advantage in prior versions of the jvm because of synchonization overhead in several io related classes, but modern jvm are pretty good at removing unneeded locks.

EventHandler handler = (s, e) => MessageBox.Show("Woho");

button.Click += handler;
button.Click -= handler;

var iframeInner = jQuery(iframe).find('iframe').contents();

var iframeContent = jQuery(iframeInner).contents().find('#element');

iframeInner contains elements from

<div id="element">other markup goes here</div> 

and iframeContent will find for elements which are inside of

 <div id="element">other markup goes here</div> 

(find doesn't search on current element) that's why it is returning null.

.val() always works with textarea elements.

.text() works sometimes and fails other times! It's not reliable (tested in Chrome 33)

What's best is that .val() works seamlessly with other form elements too (like input) whereas .text() fails.

Try using setAttribute on the result:

result.setAttribute("class","red"); 

I had the same error and ended up solving it by upgrading my Oracle ojdbc driver to a version compatible with the Oracle database version

From the documentation:

/is Includes the same files. /it Includes "tweaked" files.

"Same files" means files that are identical (name, size, times, attributes). "Tweaked files" means files that have the same name, size, and times, but different attributes.

robocopy src dst sample.txt /is      # copy if attributes are equal
robocopy src dst sample.txt /it      # copy if attributes differ
robocopy src dst sample.txt /is /it  # copy irrespective of attributes

This answer on Super User has a good explanation of what kind of files the selection parameters match.

With that said, I could reproduce the behavior you describe, but from my understanding of the documentation and the output robocopy generated in my tests I would consider this a bug.

The file is listed as copied, and since it becomes a same file after the first robocopy run at least the times are synced. However, even though seven bytes have been copied according to the output no data was actually written to the destination file in both cases despite the data flag being set (via /copyall). The behavior also doesn't change if the data flag is set explicitly (/copy:d).

I had to modify the last write time to get robocopy to actually synchronize the data.

An admittedly ugly workaround would be to change the last write time of same/tweaked files to force robocopy to copy the data:

& robocopy src dst /is /it /l /ndl /njh /njs /ns /nc |
  Where-Object { $_.Trim() } |
  ForEach-Object {
    $f = Get-Item $_
    $f.LastWriteTime = $f.LastWriteTime.AddSeconds(1)
  }
& robocopy src dst /copyall /mir

Switching to xcopy is probably your best option:

& xcopy src dst /k/r/e/i/s/c/h/f/o/x/y

In your component, you can call this.forceUpdate() to force a rerender.

I just found this when googling to solve the same problem, and had to make a minor change to the solution to make it work in my situation, as I had 2 similar substrings, "Sun" and "Sunstruck" to search for. The offered solution was locating the wrong entry when searching for "Sun". Data in column B

I added another column C, formulaes C1=" "&B1&" " and changed the search to =COUNTIF(B1:B10,"* "&A1&" *")>0, the extra column to allow finding the first of last entry in the concatenated string.

I had the exact same error but in my case, the problem was the result of having rebuilt Apache after an upgrade to the PHP version. Long story short, I forgot to install the Apache module 'suexec'.

It had nothing to do with group or ownership. That only took me two days to figure out, someone shoot me...

use below code it helps you....

        BitmapFactory.Options options = new BitmapFactory.Options();

        options.inSampleSize = 4;
        options.inPurgeable = true;
        Bitmap bm = BitmapFactory.decodeFile("your path of image",options);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();

        bm.compress(Bitmap.CompressFormat.JPEG,40,baos); 


        // bitmap object

        byteImage_photo = baos.toByteArray();

                    //generate base64 string of image

                   String encodedImage =Base64.encodeToString(byteImage_photo,Base64.DEFAULT);

  //send this encoded string to server

You can use the -quit option of find:

find <dir> -maxdepth 1 -type d -name '*foo*' -print -quit

If you're using Visual Studio you need to modify the project property: Configuration Properties -> Linker -> System -> SubSystem.

This should be set to: Console (/SUBSYSTEM:CONSOLE)

Also you should change your WinMain to be this signature:

int main(int argc, char **argv)
{
    //...
    return 0;
}

JB hit the nail on the head. The only thing I can add is that Java 8 doesn't do pure parallel processing, it does paraquential. Yes I wrote the article and I've been doing F/J for thirty years so I do understand the issue.

Simply by iterating over the list:

struct node *n = head;
while(n){
   struct node *n1 = n;
   n = n->next;
   free(n1);
}

You have to set to element_blank() in theme() elements you need to remove

  theme(axis.title.x=element_blank(),
        axis.text.x=element_blank(),
        axis.ticks.x=element_blank())

using the java-8 stream api you can sort an ArrayList by:

 Comparator<Person> birthdayComparator = Comparator.comparing(Person::getBirthday);
 List<Person> sortedList = list.stream().sorted(birthdayComparator).collect(toList());

I had this problem too but the cause was different. I'm using VS2017 with F# 4.0.

Firstly, the console in Visual Studio does not give you enough details why the tests could not be found; it will just fail to the load the DLL with the tests. So use NUnit3console.exe on the command line as this gives you more details.

In my case, it was because the test adapter was looking for a newer version of the F# Core DLL (4.4.1.0) (F# 4.1) whereas I'm still using 4.4.0.0 (F# 4.0). So I just added this to the app.config of the test project:-

  <dependentAssembly>
    <assemblyIdentity name="FSharp.Core" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="4.4.0.0" />
  </dependentAssembly>

i.e. redirect to the earlier F# core.

foreach (DataGridViewRow row in datagrid.Rows)
                        row.HeaderCell.Value = String.Format("{0}", row.Index + 1);

If you wanna compare Spring MVC with struts consider below benefit of Spring MVC over Struts.

1. Spring provides a very clean division between controllers, JavaBean models, and views.
2. Spring's MVC is very flexible. Unlike Struts, which forces your Action and Form objects into concrete inheritance (thus taking away your single shot at concrete inheritance in Java), Spring MVC is entirely based on interfaces. Furthermore, just about every part of the Spring MVC framework is configurable via plugging in your own interface. Of course we also provide convenience classes as an implementation option.
3. Spring, like WebWork, provides interceptors as well as controllers, making it easy to factor out behavior common to the handling of many requests.
4. Spring MVC is truly view-agnostic. You don't get pushed to use JSP if you don't want to; you can use Velocity, XLST or other view technologies. If you want to use a custom view mechanism - for example, your own templating language - you can easily implement the Spring View interface to integrate it.
5. Spring Controllers are configured via IoC like any other objects. This makes them easy to test, and beautifully integrated with other objects managed by Spring.
6. Spring MVC web tiers are typically easier to test than Struts web tiers, due to the avoidance of forced concrete inheritance and explicit dependence of controllers on the dispatcher servlet.
7. The web tier becomes a thin layer on top of a business object layer. This encourages good practice. Struts and other dedicated web frameworks leave you on your own in implementing your business objects; Spring provides an integrated framework for all tiers of your application

This error will also appear if you try to connect to an exposed port from within a Docker container, when nothing is actively serving the port.

On a host where nothing is listening/bound to that port you'd get a No connection could be made because the target machine actively refused it error instead when making a request to a local URL that is not served, eg: localhost:5000. However, if you start a container that binds to the port, but there is no server running inside of it actually serving the port, any requests to that port on localhost will result in:

• [Errno 99] Cannot assign requested address (if called from within the container), or
• [Errno 0] Error (if called from outside of the container).

You can reproduce this error and the behaviour described above as follows:

Start a dummy container (note: this will pull the python image if not found locally):

docker run --name serv1 -p 5000:5000 -dit python

Then for [Errno 0] Error enter a Python console on host, while for [Errno 99] Cannot assign requested address access a Python console on the container by calling:

docker exec -it -u 0 serv1 python

And then in either case call:

import urllib.request
urllib.request.urlopen('https://localhost:5000')

I concluded with treating either of these errors as equivalent to No connection could be made because the target machine actively refused it rather than trying to fix their cause - although please advise if that's a bad idea.

I've spent over a day figuring this one out, given that all resources and answers I could find on the [Errno 99] Cannot assign requested address point in the direction of binding to an occupied port, connecting to an invalid IP, sysctl conflicts, docker network issues, TIME_WAIT being incorrect, and many more things. Therefore I wanted to leave this answer here, despite not being a direct answer to the question at hand, given that it can be a common cause for the error described in this question.

For Python 3.5+:

So, you can get the stacktrace from your exception as from any other exception. Use traceback.TracebackException for it (just replace ex with your exception):

print("".join(traceback.TracebackException.from_exception(ex).format())

An extended example and other features to do this:

import traceback

try:
    1/0
except Exception as ex:
    print("".join(traceback.TracebackException.from_exception(ex).format()) == traceback.format_exc() == "".join(traceback.format_exception(type(ex), ex, ex.__traceback__))) # This is True !!
    print("".join(traceback.TracebackException.from_exception(ex).format()))

The output will be something like this:

True
Traceback (most recent call last):
  File "untidsfsdfsdftled.py", line 29, in <module>
    1/0
ZeroDivisionError: division by zero

Another way to do this solely with css:

input[type='checkbox'] {
  float: left;
  width: 20px;
}
input[type='checkbox'] + label {
  display: block;
  width: 30px;
}

Note that this forces each checkbox and its label onto a separate line, rather than only doing so only when there's overflow.

If you haven't pushed your changes yet use git reset --soft [Hash for one commit] to rollback to a specific commit. --soft tells git to keep the changes being rolled back (i.e., mark the files as modified). --hard tells git to delete the changes being rolled back.

Right should do:

select RIGHT('abcdeffff',4)

First add the long press gesture recognizer to the table view:

UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] 
  initWithTarget:self action:@selector(handleLongPress:)];
lpgr.minimumPressDuration = 2.0; //seconds
lpgr.delegate = self;
[self.myTableView addGestureRecognizer:lpgr];
[lpgr release];

Then in the gesture handler:

-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self.myTableView];

    NSIndexPath *indexPath = [self.myTableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    } else if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
        NSLog(@"long press on table view at row %ld", indexPath.row);
    } else {
        NSLog(@"gestureRecognizer.state = %ld", gestureRecognizer.state);
    }
}

You have to be careful with this so that it doesn't interfere with the user's normal tapping of the cell and also note that handleLongPress may fire multiple times (this will be due to the gesture recognizer state changes).

Another approach is by using FormBody.Builder().
Here's an example of callback:

Callback loginCallback = new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        try {
            Log.i(TAG, "login failed: " + call.execute().code());
        } catch (IOException e1) {
            e1.printStackTrace();
        }
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        // String loginResponseString = response.body().string();
        try {
            JSONObject responseObj = new JSONObject(response.body().string());
            Log.i(TAG, "responseObj: " + responseObj);
        } catch (JSONException e) {
            e.printStackTrace();
        }
        // Log.i(TAG, "loginResponseString: " + loginResponseString);
    }
};

Then, we create our own body:

RequestBody formBody = new FormBody.Builder()
        .add("username", userName)
        .add("password", password)
        .add("customCredential", "")
        .add("isPersistent", "true")
        .add("setCookie", "true")
        .build();

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(this)
        .build();
Request request = new Request.Builder()
        .url(loginUrl)
        .post(formBody)
        .build();

Finally, we call the server:

client.newCall(request).enqueue(loginCallback);

There's 2 likely reasons that a TaskCanceledException would be thrown:

1. Something called Cancel() on the CancellationTokenSource associated with the cancellation token before the task completed.
2. The request timed out, i.e. didn't complete within the timespan you specified on HttpClient.Timeout.

My guess is it was a timeout. (If it was an explicit cancellation, you probably would have figured that out.) You can be more certain by inspecting the exception:

try
{
    var response = task.Result;
}
catch (TaskCanceledException ex)
{
    // Check ex.CancellationToken.IsCancellationRequested here.
    // If false, it's pretty safe to assume it was a timeout.
}

In getUserById you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user. Otherwise Hibernate.initialize(user); is actually Hibernate.initialize(null);

Here's the new getUserById (I haven't tested this ;)):

public User getUserById(Long user_id) {
    Session session = null;
    Object user = null;
    try {
        session = HibernateUtil.getSessionFactory().openSession();
        user = (User)session.load(User.class, user_id);
        Hibernate.initialize(user);
    } catch (Exception e) {
       e.printStackTrace();
    } finally {
        if (session != null && session.isOpen()) {
            session.close();
        }
    }
    return user;
}

There is also difference is in plan handling.

Oracle is able form an optimized plan with concatenation of branch filters when search contains comparison of nvl result with an indexed column.

create table tt(a, b) as
select level, mod(level,10)
from dual
connect by level<=1e4;

alter table tt add constraint ix_tt_a primary key(a);
create index ix_tt_b on tt(b);

explain plan for
select * from tt
where a=nvl(:1,a)
  and b=:2;

explain plan for
select * from tt
where a=coalesce(:1,a)
  and b=:2;

I'm not sure for JPA 1.0 but you can pass a Collection in JPA 2.0:

String qlString = "select item from Item item where item.name IN :names"; 
Query q = em.createQuery(qlString, Item.class);

List<String> names = Arrays.asList("foo", "bar");

q.setParameter("names", names);
List<Item> actual = q.getResultList();

assertNotNull(actual);
assertEquals(2, actual.size());

Tested with EclipseLInk. With Hibernate 3.5.1, you'll need to surround the parameter with parenthesis:

String qlString = "select item from Item item where item.name IN (:names)";

But this is a bug, the JPQL query in the previous sample is valid JPQL. See HHH-5126.

You could do the following:

• Let the shutdown hook set some AtomicBoolean (or volatile boolean) "keepRunning" to false
• (Optionally, .interrupt the working threads if they wait for data in some blocking call)
• Wait for the working threads (executing writeBatch in your case) to finish, by calling the Thread.join() method on the working threads.
• Terminate the program

Some sketchy code:

• Add a static volatile boolean keepRunning = true;

• In run() you change to

  for (int i = 0; i < N && keepRunning; ++i)
      writeBatch(pw, i);
  

• In main() you add:

  final Thread mainThread = Thread.currentThread();
  Runtime.getRuntime().addShutdownHook(new Thread() {
      public void run() {
          keepRunning = false;
          mainThread.join();
      }
  });
  

That's roughly how I do a graceful "reject all clients upon hitting Control-C" in terminal.

From the docs:

When the virtual machine begins its shutdown sequence it will start all registered shutdown hooks in some unspecified order and let them run concurrently. When all the hooks have finished it will then run all uninvoked finalizers if finalization-on-exit has been enabled. Finally, the virtual machine will halt.

That is, a shutdown hook keeps the JVM running until the hook has terminated (returned from the run()-method.

Hash functions for algorithmic use have usually 2 goals, first they have to be fast, second they have to evenly distibute the values across the possible numbers. The hash function also required to give the all same number for the same input value.

if your values are strings, here are some examples for bad hash functions:

1. string[0] - the ASCII characters a-Z are way more often then others
2. string.lengh() - the most probable value is 1

Good hash functions tries to use every bit of the input while keeping the calculation time minimal. If you only need some hash code, try to multiply the bytes with prime numbers, and sum them.

Below is the link which guide in parsing JSON string in android.

http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE

Also according to your json string code snippet must be something like this:-

JSONObject mainObject = new JSONObject(yourstring);

JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");  
JSONString url = universityObject.getString("url");

Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)

Same for other object.

Building upon busylee's answer, this is how you can make a drawable that only has one unrounded corner (top-left, in this example):

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/white" />
            <!-- A numeric value is specified in "radius" for demonstrative purposes only,
                  it should be @dimen/val_name -->
            <corners android:radius="10dp" />
        </shape>
    </item>
    <!-- To keep the TOP-LEFT corner UNROUNDED set both OPPOSITE offsets (bottom+right): -->
    <item
        android:bottom="10dp"
        android:right="10dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/white" />
        </shape>
    </item>
</layer-list>

Please note that the above drawable is not shown correctly in the Android Studio preview (2.0.0p7). To preview it anyway, create another view and use this as android:background="@drawable/...".
