This is an extension to Pache's answer using Guava's ListenableFuture.

In particular, Futures.transform() returns ListenableFuture so can be used to chain async calls. Futures.addCallback() returns void, so cannot be used for chaining, but is good for handling success/failure on an async completion.

// ListenableFuture1: Open Database
ListenableFuture<Database> database = service.submit(() -> openDatabase());

// ListenableFuture2: Query Database for Cursor rows
ListenableFuture<Cursor> cursor =
    Futures.transform(database, database -> database.query(table, ...));

// ListenableFuture3: Convert Cursor rows to List<Foo>
ListenableFuture<List<Foo>> fooList =
    Futures.transform(cursor, cursor -> cursorToFooList(cursor));

// Final Callback: Handle the success/errors when final future completes
Futures.addCallback(fooList, new FutureCallback<List<Foo>>() {
  public void onSuccess(List<Foo> foos) {
    doSomethingWith(foos);
  }
  public void onFailure(Throwable thrown) {
    log.error(thrown);
  }
});

NOTE: In addition to chaining async tasks, Futures.transform() also allows you to schedule each task on a separate executor (Not shown in this example).

You can avoid the loop and cut etc by using:

awk -F ':' '{system("ping " $1);}' config.txt

However it would be better if you post a snippet of your config.txt

Here's how you read a file, and then write to it (overwriting any existing data), without closing and reopening:

with open(filename, "r+") as f:
    data = f.read()
    f.seek(0)
    f.write(output)
    f.truncate()

Go to Project location in Specified Folder

C:\Angular6\sample>

Here you can type the command

C:\Angular6\sample>ng g c users

Here g means generate , c means component ,users is the component name

it will generate the 4 files

users.component.html,
users.component.spec.ts,
users.component.ts,
users.component.css

A very interesting project is disruptor. It has a ringbuffer and is used from what I know in financial applications.

See here: code of ringbuffer

I checked both Guava's EvictingQueue and ArrayDeque.

ArrayDeque does not limit growth if it's full it will double size and hence is not precisely acting like a ringbuffer.

EvictingQueue does what it promises but internally uses a Deque to store things and just bounds memory.

Hence, if you care about memory being bounded ArrayDeque is not fullfilling your promise. If you care about object count EvictingQueue uses internal composition (bigger object size).

A simple and memory efficient one can be stolen from jmonkeyengine. verbatim copy

  private T[] buffer;          // queue elements

  private int indexOut = 0;       // index of first element of queue
  private int indexIn = 0;       // index of next available slot

  // cast needed since no generic array creation in Java
  public RingBuffer(int capacity) {
    buffer = (T[]) new Object[capacity];
  }

  public boolean isEmpty() {
    return count == 0;
  }

  public int size() {
    return count;
  }

  public void push(T item) {
    if (count == buffer.length) {
        throw new RuntimeException("Ring buffer overflow");
    }
    buffer[indexIn] = item;
    indexIn = (indexIn + 1) % buffer.length;     // wrap-around
    count++;
  }

  public T pop() {
    if (isEmpty()) {
        throw new RuntimeException("Ring buffer underflow");
    }
    T item = buffer[indexOut];
    buffer[indexOut] = null;                  // to help with garbage collection
    count--;
    indexOut = (indexOut + 1) % buffer.length; // wrap-around
    return item;
  }

  public Iterator<T> iterator() {
    return new RingBufferIterator();
  }

  // an iterator, doesn't implement remove() since it's optional
  private class RingBufferIterator implements Iterator<T> {

    private int i = 0;

    public boolean hasNext() {
        return i < count;
    }

    public void remove() {
        throw new UnsupportedOperationException();
    }

    public T next() {
        if (!hasNext()) {
            throw new NoSuchElementException();
        }
        return buffer[i++];
    }
  }
}

You can try the free VS2010 extension: Reference Assistant by Lardite group. It works perfectly for me. This tool helps to find unused references and allows you to choose which references should be removed.

I wrote this handy piece to sort by multiple columns / properties of an object. With each successive column click, the code stores the last column clicked and adds it to a growing list of clicked column string names, placing them in an array called sortArray. The built-in Angular "orderBy" filter simply reads the sortArray list and orders the columns by the order of column names stored there. So the last clicked column name becomes the primary ordered filter, the previous one clicked the next in precedence, etc. The reverse order affects all columns order at once and toggles ascending/descending for the complete array list set:

<script>
    app.controller('myCtrl', function ($scope) {
        $scope.sortArray = ['name'];
        $scope.sortReverse1 = false;
        $scope.searchProperty1 = '';
        $scope.addSort = function (x) {
            if ($scope.sortArray.indexOf(x) === -1) {
                $scope.sortArray.splice(0,0,x);//add to front
            }
            else {
                $scope.sortArray.splice($scope.sortArray.indexOf(x), 1, x);//remove
                $scope.sortArray.splice(0, 0, x);//add to front again
            }
        };
        $scope.sushi = [
        { name: 'Cali Roll', fish: 'Crab', tastiness: 2 },
        { name: 'Philly', fish: 'Tuna', tastiness: 2 },
        { name: 'Tiger', fish: 'Eel', tastiness: 7 },
        { name: 'Rainbow', fish: 'Variety', tastiness: 6 },
        { name: 'Salmon', fish: 'Misc', tastiness: 2 }
        ];
    });
</script>
<table style="border: 2px solid #000;">
<thead>
    <tr>
        <td><a href="#" ng-click="addSort('name');sortReverse1=!sortReverse1">NAME<span ng-show="sortReverse1==false">&#9660;</span><span ng-show="sortReverse1==true">&#9650;</span></a></td>

You can delete the browser cache by setting these headers:

<?php
header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
?>

You can register a BroadcastReceiver to be notified when a WiFi connection is established (or if the connection changed).

Register the BroadcastReceiver:

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
registerReceiver(broadcastReceiver, intentFilter);

And then in your BroadcastReceiver do something like this:

@Override
public void onReceive(Context context, Intent intent) {
    final String action = intent.getAction();
    if (action.equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION)) {
        if (intent.getBooleanExtra(WifiManager.EXTRA_SUPPLICANT_CONNECTED, false)) {
            //do stuff
        } else {
            // wifi connection was lost
        }
    }
}

For more info, see the documentation for BroadcastReceiver and WifiManager

Of course you should check whether the device is already connected to WiFi before this.

EDIT: Thanks to ban-geoengineering, here's a method to check whether the device is already connected:

private boolean isConnectedViaWifi() {
     ConnectivityManager connectivityManager = (ConnectivityManager) appObj.getSystemService(Context.CONNECTIVITY_SERVICE);
     NetworkInfo mWifi = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);     
     return mWifi.isConnected();
}

If what you want can't be achieved satisfactorily without having the initialization in its own method (e.g. because you want to do too much before the initialization code, or wrap it in a try-finally, or whatever) you can have any or all constructors pass the readonly variables by reference to an initialization routine, which will then be able to manipulate them at will.

public class Sample
{
    private readonly int _intField;
    public int IntProperty => _intField; 

    private void setupStuff(ref int intField, int newValue) => intField = newValue;

    public Sample(string theIntAsString)
    {
        int i = int.Parse(theIntAsString);
        setupStuff(ref _intField,i);
    }

    public Sample(int theInt) => setupStuff(ref _intField, theInt);
}

Check this:

http://jsfiddle.net/SxKr5/3/

.hero1
{
    width: 90%;
    height: 200px;
    margin: auto;
    background-color: #e15915;
}

.hero2
{
    width: 0px;
    height: 0px;
    border-style: solid;
    margin: auto;
    border-width: 90px 58px 0 58px;
    border-color: #e15915 transparent transparent transparent;
    line-height: 0px;
    _border-color: #e15915 #000000 #000000 #000000;
    _filter: progid:DXImageTransform.Microsoft.Chroma(color='#000000')
}

This is what you need:

comboBox1.ResetText();

To set thousand separator, say 123,456.78 you have to use DecimalFormat:

     DecimalFormat df = new DecimalFormat("#,###.00");
     System.out.println(df.format(new BigDecimal(123456.75)));
     System.out.println(df.format(new BigDecimal(123456.00)));
     System.out.println(df.format(new BigDecimal(123456123456.78)));

Here is the result:

123,456.75
123,456.00
123,456,123,456.78

Although I set #,###.00 mask, it successfully formats the longer values too. Note that the comma(,) separator in result depends on your locale. It may be just space( ) for Russian locale.

The problem is in this line:

with pattern.findall(row) as f:

You are using the with statement. It requires an object with __enter__ and __exit__ methods. But pattern.findall returns a list, with tries to store the __exit__ method, but it can't find it, and raises an error. Just use

f = pattern.findall(row)

instead.

Ideally, you would refactor to pass an object and merge it with a default object, so the order in which arguments are passed doesn't matter (see the second section of this answer, below).

If, however, you just want something quick, reliable, easy to use and not bulky, try this:

A clean quick fix for any number of default arguments

• It scales elegantly: minimal extra code for each new default
• You can paste it anywhere: just change the number of required args and variables
• If you want to pass undefined to an argument with a default value, this way, the variable is set as undefined. Most other options on this page would replace undefined with the default value.

Here's an example for providing defaults for three optional arguments (with two required arguments)

function myFunc( requiredA, requiredB,  optionalA, optionalB, optionalC ) {

  switch (arguments.length - 2) { // 2 is the number of required arguments
    case 0:  optionalA = 'Some default';
    case 1:  optionalB = 'Another default';
    case 2:  optionalC = 'Some other default';
    // no breaks between cases: each case implies the next cases are also needed
  }

}

Simple demo. This is similar to roenving's answer, but easily extendible for any number of default arguments, easier to update, and using arguments not Function.arguments.

Passing and merging objects for more flexibility

The above code, like many ways of doing default arguments, can't pass arguments out of sequence, e.g., passing optionalC but leaving optionalB to fall back to its default.

A good option for that is to pass objects and merge with a default object. This is also good for maintainability (just take care to keep your code readable, so future collaborators won't be left guessing about the possible contents of the objects you pass around).

Example using jQuery. If you don't use jQuery, you could instead use Underscore's _.defaults(object, defaults) or browse these options:

function myFunc( args ) {
  var defaults = {
    optionalA: 'Some default',
    optionalB: 'Another default',
    optionalC: 'Some other default'
  };
  args = $.extend({}, defaults, args);
}

Here's a simple example of it in action.

Keep in mind that @"%d" will only work on 32 bit. Once you start using NSInteger for compatibility if you ever compile for a 64 bit platform, you should use @"%ld" as your format specifier.

This is another way:

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int pos, long arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

You can use concatenation operator and instead of declaring two variables only use one variable

String finalString =  cursor.getString(numcol) + cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE));

The updated dplyr solution, as for 2020

I discovered the Open XML SDK since my original answer. It provides strongly typed classes for spreadsheet objects, among other things, and seems to be fairly easy to work with. I am going to use it for reports in one of my projects. Alas, version 2.0 is not supposed to get released until late 2009 or 2010.

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

I think you want to get parent folder name from file path. It is easy to get. One way is to create a FileInfo type object and use its Directory property.

Example:

FileInfo fInfo = new FileInfo("c:\projects\roott\wsdlproj\devlop\beta2\text\abc.txt");

String dirName = fInfo.Directory.Name;

Git v2.0 Release Notes

Backward compatibility notes

When git push [$there] does not say what to push, we have used the traditional "matching" semantics so far (all your branches were sent to the remote as long as there already are branches of the same name over there). In Git 2.0, the default is now the "simple" semantics, which pushes:

• only the current branch to the branch with the same name, and only when the current branch is set to integrate with that remote branch, if you are pushing to the same remote as you fetch from; or

• only the current branch to the branch with the same name, if you are pushing to a remote that is not where you usually fetch from.

You can use the configuration variable "push.default" to change this. If you are an old-timer who wants to keep using the "matching" semantics, you can set the variable to "matching", for example. Read the documentation for other possibilities.

When git add -u and git add -A are run inside a subdirectory without specifying which paths to add on the command line, they operate on the entire tree for consistency with git commit -a and other commands (these commands used to operate only on the current subdirectory). Say git add -u . or git add -A . if you want to limit the operation to the current directory.

git add <path> is the same as git add -A <path> now, so that git add dir/ will notice paths you removed from the directory and record the removal. In older versions of Git, git add <path> used to ignore removals. You can say git add --ignore-removal <path> to add only added or modified paths in <path>, if you really want to.

Same problem with Anaconda running on Ubuntu 15.10. I closed the terminal and opened a new window and it worked fine.

That probably means that your id is an AUTO_INCREMENT integer and you're trying to send a string. You should specify a column list and omit it from your INSERT.

INSERT INTO workorders (column1, column2) VALUES ($column1, $column2)

CREATE VIEW MyView AS

Note: Unless the View is very complicated, MySQL will optimize this just fine.

user

The maximum total length of a user name is 64 characters.

domain

Maximum of 255 characters in the domain part (the one after the “@”)

However, there is a restriction in RFC 2821 reading:

The maximum total length of a reverse-path or forward-path is 256 characters, including the punctuation and element separators”. Since addresses that don’t fit in those fields are not normally useful, the upper limit on address lengths should normally be considered to be 256, but a path is defined as: Path = “<” [ A-d-l “:” ] Mailbox “>” The forward-path will contain at least a pair of angle brackets in addition to the Mailbox, which limits the email address to 254 characters.

If the jar's in your classpath, and you know its Main class, you can just invoke the main class. Using DITA-OT as an example:

import org.dita.dost.invoker.CommandLineInvoker;
....
CommandLineInvoker.main('-f', 'html5', '-i', 'samples/sequence.ditamap', '-o', 'test')

Note this will make the subordinate jar share memory space and a classpath with your jar, with all the potential for interference that can cause. If you don't want that stuff polluted, you have other options, as mentioned above - namely:

• create a new ClassLoader with the jar in it. This is more safe; you can at least isolate the new jar's knowledge to a core classloader if you architect things with the knowledge that you'll be making use of alien jars. It's what we do in my shop for our plugins system; the main application is a tiny shell with a ClassLoader factory, a copy of the API, and knowledge that the real application is the first plugin for which it should build a ClassLoader. Plugins are a pair of jars - interface and implementation - that are zipped up together. The ClassLoaders all share all the interfaces, while each ClassLoader only has knowledge of its own implementation. The stack's a little complex, but it passes all tests and works beautifully.
• use Runtime.getRuntime.exec(...) (which wholly isolates the jar, but has the normal "find the application", "escape your strings right", "platform-specific WTF", and "OMG System Threads" pitfalls of running system commands.

Your python don't know where you installed scipy. add the scipy path to PYTHONPATH and I hope it will solve your problem.

I fixed this issue by installing jre, I have jdk already installed but jre was not installed.

SelectAllOnFocus works the first time the EditText gets focus, but if you want to select the text every time the user clicks on it, you need to call editText.clearFocus() in between times.

For example, if your app has one EditText and one button, clicking the button after changing the EditText leaves the focus in the EditText. Then the user has to use the cursor handle and the backspace key to delete what's in the EditText before they can enter a new value. So call editText.clearFocus() in the Button's onClick method.

Try this code:

var myXmlDocument = new XmlDocument();
myXmlDocument.LoadXml(theString);

A real literal suffixed by M or m is of type decimal (money). For example, the literals 1m, 1.5m, 1e10m, and 123.456M are all of type decimal. This literal is converted to a decimal value by taking the exact value, and, if necessary, rounding to the nearest representable value using banker's rounding. Any scale apparent in the literal is preserved unless the value is rounded or the value is zero (in which latter case the sign and scale will be 0). Hence, the literal 2.900m will be parsed to form the decimal with sign 0, coefficient 2900, and scale 3.

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

In pyspark,SparkSql syntax:

where column_n like 'xyz%'

might not work.

Use:

where column_n RLIKE '^xyz' 

This works perfectly fine.

Another library is 4Suite: http://sourceforge.net/projects/foursuite/

I do not know how spec-compliant it is. But it has worked very well for my use. It looks abandoned.

Since it takes 2 mins to respond, you can increase the timeout to 3 mins by adding the below code

scGetruntotals.CommandTimeout = 180;

Note : the parameter value is in seconds.

Both your way and @Steve's way are acceptable ways to prevent accidental exits.

If choosing to continue with your implementation, you will need to make sure to have backpress initialized to 0, and probably implement a Timer of some sort to reset it back to 0 on keypress, after a cooldown period. (~5 seconds seems right)

I tried the code provided above, but it gave an error 9 for me. I made this code, and it worked fine for my purposes. I hope others find it useful as well.

Function mergeArrays(ByRef arr1() As Variant, arr2() As Variant) As Variant

    Dim returnThis() As Variant
    Dim len1 As Integer, len2 As Integer, lenRe As Integer, counter As Integer
    len1 = UBound(arr1)
    len2 = UBound(arr2)
    lenRe = len1 + len2
    ReDim returnThis(1 To lenRe)
    counter = 1

    Do While counter <= len1 'get first array in returnThis
        returnThis(counter) = arr1(counter)
        counter = counter + 1
    Loop
    Do While counter <= lenRe 'get the second array in returnThis
        returnThis(counter) = arr2(counter - len1)
        counter = counter + 1
    Loop

mergeArrays = returnThis

Facelets is a XML based view technology. The & is a special character in XML representing the start of an entity like & which ends with the ; character. You'd need to either escape it, which is ugly:

rendered="#{beanA.prompt == true && beanB.currentBase != null}"

or to use the and keyword instead, which is preferred as to readability and maintainability:

rendered="#{beanA.prompt == true and beanB.currentBase != null}"

See also:

• Java EE 6 tutorial - Operators in EL

Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true:

rendered="#{beanA.prompt and beanB.currentBase != null}"

The following should work:

setlocal EnableDelayedExpansion
for /F "tokens=*" %%a in ('type %FileName%') do (
    set "z=%%a"
    echo %z%
    echo %%a
)

sudo ln -s /usr/lib/jvm/java-7-oracle/jre /usr/lib/jvm/default-java

Create a symbolic link to the default-java directory.

You can find your java directory by

readlink -f $(which java) 
# outputs: /usr/lib/jvm/java-7-oracle/jre/bin/java
# Remove the last `/bin/java` and use it in above symbolic link command.

Quoting spaces inside variables such that the shell will re-interpret things properly is hard. It's this type of thing that prompts me to reach for a stronger language. Whether that's perl or python or ruby or whatever (I choose perl, but that's not always for everyone), it's just something that will allow you to bypass the shell for quoting.

It's not that I've never managed to get it right with liberal doses of eval, but just that eval gives me the eebie-jeebies (becomes a whole new headache when you want to take user input and eval it, though in this case you'd be taking stuff that you wrote and evaling that instead), and that I've gotten headaches in debugging.

With perl, as my example, I'd be able to do something like:

@tar_cmd = ( qw(tar cv), $directory );
@encrypt_cmd = ( qw(openssl des3 -salt) );
@split_cmd = ( qw(split -b 1024m -), $backup_file );

The hard part here is doing the pipes - but a bit of IO::Pipe, fork, and reopening stdout and stderr, and it's not bad. Some would say that's worse than quoting the shell properly, and I understand where they're coming from, but, for me, this is easier to read, maintain, and write. Heck, someone could take the hard work out of this and create a IO::Pipeline module and make the whole thing trivial ;-)

Let me recommend mem_top tool I created

for people who need CGO enabled and cross compile from OSX targeting windows

I needed CGO enabled while compiling for windows from my mac since I had imported the https://github.com/mattn/go-sqlite3 and it needed it. Compiling according to other answers gave me and error:

/usr/local/go/src/runtime/cgo/gcc_windows_amd64.c:8:10: fatal error: 'windows.h' file not found

If you're like me and you have to compile with CGO. This is what I did:

1.We're going to cross compile for windows with a CGO dependent library. First we need a cross compiler installed like mingw-w64

brew install mingw-w64

This will probably install it here /usr/local/opt/mingw-w64/bin/.

2.Just like other answers we first need to add our windows arch to our go compiler toolchain now. Compiling a compiler needs a compiler (weird sentence) compiling go compiler needs a separate pre-built compiler. We can download a prebuilt binary or build from source in a folder eg: ~/Documents/go now we can improve our Go compiler, according to top answer but this time with CGO_ENABLED=1 and our separate prebuilt compiler GOROOT_BOOTSTRAP(Pooya is my username):

cd /usr/local/go/src
sudo GOOS=windows GOARCH=amd64 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean
sudo GOOS=windows GOARCH=386 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean

3.Now while compiling our Go code use mingw to compile our go file targeting windows with CGO enabled:

GOOS="windows" GOARCH="386" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/i686-w64-mingw32-gcc" go build hello.go
GOOS="windows" GOARCH="amd64" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/x86_64-w64-mingw32-gcc" go build hello.go

xml:space="preserve" has to work for all compliant XML parsers.

However, note that in HTML the line break is just whitespace and NOT a line break (this is represented with the <br /> (X)HTML tag, maybe this is the problem which you are facing.

You can also add 
 and/or 
 to insert CR/LF characters.

You mention C# in your question so it may help to think of as XSD as serving a similar role to a C# interface.

It defines what the XML should 'look like' in a similar way that an interface defines what a class should implement.

window.location = myUrl;

Anyway, this is not jQuery: it's plain javascript

There also exists a UNIQUE KEY. The main difference between PRIMARY KEY and UNIQUE KEY is that the PRIMARY KEY never takes NULL value while a UNIQUE KEY may take NULL value. Also, there can be only one PRIMARY KEY in a table while UNIQUE KEY may be more than one.

Why not use outline? it is what you want outline:1px solid red;

UPDATE: Please note that this is a solution that should apply to older browsers or non-browser platforms, and is kept alive for instructional purposes. Please refer to @radicand 's answer below for a more up to date answer.

This is a unicode, escaped string. First the string was escaped, then encoded with unicode. To convert back to normal:

var x = "http\\u00253A\\u00252F\\u00252Fexample.com";
var r = /\\u([\d\w]{4})/gi;
x = x.replace(r, function (match, grp) {
    return String.fromCharCode(parseInt(grp, 16)); } );
console.log(x);  // http%3A%2F%2Fexample.com
x = unescape(x);
console.log(x);  // http://example.com

To explain: I use a regular expression to look for \u0025. However, since I need only a part of this string for my replace operation, I use parentheses to isolate the part I'm going to reuse, 0025. This isolated part is called a group.

The gi part at the end of the expression denotes it should match all instances in the string, not just the first one, and that the matching should be case insensitive. This might look unnecessary given the example, but it adds versatility.

Now, to convert from one string to the next, I need to execute some steps on each group of each match, and I can't do that by simply transforming the string. Helpfully, the String.replace operation can accept a function, which will be executed for each match. The return of that function will replace the match itself in the string.

I use the second parameter this function accepts, which is the group I need to use, and transform it to the equivalent utf-8 sequence, then use the built - in unescape function to decode the string to its proper form.

Instead of getting all the table columns using * in your sql statement, you use to specify the table columns you need.

You can use the SQL statement something like:

SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS FIRSTNAME FROM customer;

BTW, why couldn't you use FullName instead of FirstName? Like this:

SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS 'CUSTOMER NAME' FROM customer;

In python the with keyword is used when working with unmanaged resources (like file streams). It is similar to the using statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally blocks.

From Python Docs:

The with statement clarifies code that previously would use try...finally blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.

The with statement is a control-flow structure whose basic structure is:

with expression [as variable]:
    with-block

The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has __enter__() and __exit__() methods).

Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with with using.

I faced the same issue, and finally i got a solution. Please go through with the below steps, if you are using MAMP.

1. Start MAMP or MAMP PRO
2. Start the server
3. Open Terminal (Applications -> Utilities)
4. Type in: (one line) ? /Applications/MAMP/Library/bin/mysql --host=localhost -uroot -proot

This works for me.

$('html').keyup(function(e){
    if(e.keyCode == 46) {
        alert('Delete key released');
    }

Select both the column you are sorting, and the column that the picture is in (I am assuming the picture is small compared to the cell, i.e. it is "in" the cell). Make sure that the object positioning property is set as "move but don't size with cells". Now if you do a sort, the pictures will move with the list being sorted.

Note - you must include the column with the picture in your range when you sort, and the picture must fit inside the cell.

The following VBA snippet will make sure all pictures in your spreadsheet have their "move and size" property set:

Sub moveAndSize()
Dim s As Shape
For Each s In ActiveSheet.Shapes
  If s.Type = msoPicture Or s.Type = msoLinkedPicture Or s.Type = msoPlaceholder Then
    s.Placement = xlMove
  End If
Next
End Sub

If you want to make sure the picture continues to fit after you move it, you can use xlMoveAndSize instead of xlMove.

If you need to add Change-Id to multiple commits, you can download the hook from your Gerrit server and run these commands to add the Change-Ids to all commits that need them at once. The example below fixes all commits on your current branch that have not yet been pushed to the upstream branch.

tmp=$(mktemp)
hook=$(readlink -f $(git rev-parse --git-dir))/hooks/commit-msg
git filter-branch -f --msg-filter "cat > $tmp; \"$hook\" $tmp; cat $tmp" @{u}..HEAD

I think this should work.

TextBox1.Height = 100;

//this should allow you to replica an animation effect for any css property, even //properties //that transform animation jQuery plugins do not allow

            function twistMyElem(){
                var ball = $('#form');
                document.getElementById('form').style.zIndex = 1;
                ball.animate({ zIndex : 360},{
                    step: function(now,fx){
                        ball.css("transform","rotateY(" + now + "deg)");
                    },duration:3000
                }, 'linear');
            } 

As an aside, it is always a good practice (and possibly a solution for this type of issue) to delete a large number of rows by using batches:

WHILE EXISTS (SELECT 1 
              FROM   YourTable 
              WHERE  <yourCondition>) 
  DELETE TOP(10000) FROM YourTable 
  WHERE  <yourCondition>

I don't know jQuery, but I do know that if you get the select element, it contains an 'options' object.

var myOpts = document.getElementById('yourselect').options;
alert(myOpts[0].value) //=> Value of the first option

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

mAddTaskButton is null because you never initialize it with:

mAddTaskButton = (Button) findViewById(R.id.addTaskButton);

before you call mAddTaskButton.setOnClickListener().

Try this code

$('window').scrollDown(function(){$(#div).hide()});

$('window').scrollUp(function(){ $(#div).show() });

Boost.Config offers these typedefs for toolsets that do not provide them natively. The documentation for this specific functionality is here: Standard Integer Types

In create-react-app relative paths for images don't seem to work. Instead, you can import an image:

import logo from './logo.png' // relative path to image 

class Nav extends Component { 
    render() {

            <img src={logo} alt={"logo"}/> 
        )  
    }
}

For people on BSD/OSX systems there's utility called lam, short for laminate. lam -s prefix file will do what you want. I use it in pipelines, eg:

find -type f -exec lam -s "{}: " "{}" \; | fzf

...which will find all files, exec lam on each of them, giving each file a prefix of its own filename. (And pump the output to fzf for searching.)

I was facing this problem even with use Illuminate\Http\Request; line at the top of my controller. Kept pulling my hair till I realized that I was doing $request::ip() instead of $request->ip(). Can happen to you if you didn't sleep all night and are looking at the code at 6am with half-opened eyes.

Hope this helps someone down the road.

Please do not reinvent the wheel. There are many open-source & COTS solutions that already exist to solve this problem.

Please take a look at the following JavaScript libraries:

You can install andle for gradle version management.

It can help you sync to the latest version almost everything in gradle file.

Simple three step to update all project at once.

1. install:

    $ sudo pip install andle

2. set sdk:

    $ andle setsdk -p <sdk_path>

3. update depedency:

    $ andle update -p <project_path> [--dryrun] [--remote] [--gradle]

--dryrun: only print result in console

--remote: check version in jcenter and mavenCentral

--gradle: check gradle version

As the comments mentioned, Go doesn't support ternary one liners. The shortest form I can think of is this:

var c int
if c = b; a > b {
    c = a
}

But please don't do that, it's not worth it and will only confuse people who read your code.

If you do this a lot, NumPy is the way to go.

If for some reason you can't use NumPy:

>>> map(lambda x:sum(x)/float(len(x)), zip(*a))
[45.0, 10.5]

In the AndroidManifest.xml, under the application tag, you can set the theme of your choice. To customize the theme, press Ctrl + Click on android:theme = "@style/AppTheme" in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

At parent= in styles.xml you can browse all available styles by using auto-complete inside the "". E.g. try parent="Theme." with your cursor right after the . and then pressing Ctrl + Space.

You can also preview themes in the preview window in Android Studio.

For me, created an empty bootstrap.css.map together with bootstrap.css and the error stopped.

Table exists or not in database in swift

func tableExists(_ tableName:String) -> Bool {
        sqlStatement = "SELECT name FROM sqlite_master WHERE type='table' AND name='\(tableName)'"
        if sqlite3_prepare_v2(database, sqlStatement,-1, &compiledStatement, nil) == SQLITE_OK {
            if sqlite3_step(compiledStatement) == SQLITE_ROW {
                return true
            }
            else {
                return false
            }
        }
        else {
            return false
        }
            sqlite3_finalize(compiledStatement)
    }

If you don't want to save method into jQuery.fn you can use

[].reverse.call($('li'));

Load the multicol package, like this \usepackage{multicol}. Then use:

\begin{multicols}{2}
Column 1
\columnbreak
Column 2
\end{multicols}

If you omit the \columnbreak, the columns will balance automatically.

It is most likely because you uninstalled some SQL Server components Visual Studio is using. Though Visual Studio still works, it's very slow.

Just go to "Programs and Features" in the Control Panel and repair Visual Studio. The needed Visual Studio components will be installed again and Visual Studio will be back as fast as before.

I know it's old, but you can:

• Create a service layer
• Move method there
• Call method in both controllers

Brian Ramsay’s code, de-pseudofied:

- (NSString*)formattedStringForDuration:(NSTimeInterval)duration
{
    NSInteger minutes = floor(duration/60);
    NSInteger seconds = round(duration - minutes * 60);
    return [NSString stringWithFormat:@"%d:%02d", minutes, seconds];
}

In ES6, just one line.

const arr = arr.filter(item => item.key !== "some value");

:)

Please make sure two things:

1- Use @Bean annotation with the method.

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder){
    return builder.build();
}

2- Scope of this method should be public not private.

Complete Example -

@Service
public class MakeHttpsCallImpl implements MakeHttpsCall {

@Autowired
private RestTemplate restTemplate;

@Override
public String makeHttpsCall() {
    return restTemplate.getForObject("https://localhost:8085/onewayssl/v1/test",String.class);
}

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder){
    return builder.build();
}
}

The jQuery documentation says that the datePicker needs to be attached to a SPAN or a DIV when it is not associated with an input box. You could do something like this:

<img src='someimage.gif' id="datepickerImage" />
<div id="datepicker"></div>

<script type="text/javascript">
 $(document).ready(function() {
    $("#datepicker").datepicker({
            changeMonth: true,
            changeYear: true,
    })
    .hide()
    .click(function() {
      $(this).hide();
    });

    $("#datepickerImage").click(function() {
       $("#datepicker").show(); 
    });
 });
</script>

Technically, no. But what you can do is use a font size that is as tall as you would like the stretched font to be, and then condense it horizontally with font-stretch.

The OP didn't actually need to pivot without agregation but for those of you coming here to know how see:

sql parameterised cte query

The answer to that question involves a situation where pivot without aggregation is needed so an example of doing it is part of the solution.

Since this is a top hit on Google, I'd like to give an updated answer.

Using ES6 classes makes inheritance and method overriding a lot easier:

'use strict';

class A {
    speak() {
        console.log("I'm A");
    }
}

class B extends A {
    speak() {
        super.speak();

        console.log("I'm B");
    }
}

var a = new A();
a.speak();
// Output:
// I'm A

var b = new B();
b.speak();
// Output:
// I'm A
// I'm B

The super keyword refers to the parent class when used in the inheriting class. Also, all methods on the parent class are bound to the instance of the child, so you don't have to write super.method.apply(this);.

As for compatibility: the ES6 compatibility table shows only the most recent versions of the major players support classes (mostly). V8 browsers have had them since January of this year (Chrome and Opera), and Firefox, using the SpiderMonkey JS engine, will see classes next month with their official Firefox 45 release. On the mobile side, Android still does not support this feature, while iOS 9, release five months ago, has partial support.

Fortunately, there is Babel, a JS library for re-compiling Harmony code into ES5 code. Classes, and a lot of other cool features in ES6 can make your Javascript code a lot more readable and maintainable.

Making use of CSS sprites and data uri gives extra interesting benefits like fast loading and less requests AND we get IE8 support by using image/base64:

.div1:after, .div2:after {
  content: '';

For IE8, change to this:

This answer is for TextInputEditText :

In the layout XML file set your input method options to your required type. for example done.

<com.google.android.material.textfield.TextInputLayout
        android:id="@+id/textInputLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:imeOptions="actionGo"/>

</com.google.android.material.textfield.TextInputLayout>

Similarly, you can also set imeOptions to actionSubmit, actionSearch, etc

In the java add the editor action listener.

TextInputLayout textInputLayout = findViewById(R.id.textInputLayout);

textInputLayout.getEditText().setOnEditorActionListener(new 

    TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_GO) {
                performYourAction();
                return true;
            }
            return false;
        }
    });

If you're using kotlin :

textInputLayout.editText.setOnEditorActionListener { _, actionId, _ ->
    if (actionId == EditorInfo.IME_ACTION_GO) {
        performYourAction()
    }
    true
}

You can push a MP3 file in your /sdcard folder using DDMS, restart the emulator, then open the Media application, browse to your MP3 file, long press on it and select "Use as phone ringtone".

Error is gone!

Edit: same trouble with notification sounds (e.g. for SMS) solved using Ringdroid application

set objExcel = CreateObject("Excel.Application")
objExcel.Application.DisplayAlerts = False
set objWorkbook=objExcel.workbooks.add()
objExcel.cells(1,1).value = "Test value"
objExcel.cells(1,2).value = "Test data"
objWorkbook.Saveas "c:\testXLS.xls"
objWorkbook.Close
objExcel.workbooks.close
objExcel.quit
set objExcel = nothing `

Here is how I got it going specifically for the admob sdk jar file:

1. Drag your jar file into the libs folder.
2. Right click on the jar file and select Add Library now the jar file is a library lets add it to the compile path
3. Open the build.gradle file (note there are two build.gradle files at least, don't use the root one use the one in your project scope).

4. Find the dependencies section (for me i was trying to the admob -GoogleAdMobAdsSdk jar file) e.g.

   dependencies {
      compile files('libs/android-support-v4.jar','libs/GoogleAdMobAdsSdk-6.3.1.jar')
   }
   

5. Last go into settings.gradle and ensure it looks something like this:

   include ':yourproject', ':yourproject:libs:GoogleAdMobAdsSdk-6.3.1'
   

6. Finally, Go to Build -> Rebuild Project

Use the Reformat and Compile plugin (inspired by the Save Actions plugin of Alexandre DuBreuil):

https://plugins.jetbrains.com/plugin/8231?pr=idea_ce

At the moment I am only offering a jar file, but this is the most important part of the code:

private final static Set<Document> documentsToProcess = new HashSet<Document>();
private static VirtualFile[] fileToCompile = VirtualFile.EMPTY_ARRAY;

// The plugin extends FileDocumentManagerAdapter.
// beforeDocumentSaving calls reformatAndCompile
private static void reformatAndCompile(
        @NotNull final Project project,
        @NotNull final Document document,
        @NotNull final PsiFile psiFile) {
    documentsToProcess.add(document);
    if (storage.isEnabled(Action.compileFile) && isDocumentActive(project, document)) {
        fileToCompile = isFileCompilable(project, psiFile.getVirtualFile());
    }
    ApplicationManager.getApplication().invokeLater(new Runnable() {
        @Override
        public void run() {
            if (documentsToProcess.contains(document)) {
                documentsToProcess.remove(document);
                if (storage.isEnabled(Action.optimizeImports)
                        || storage.isEnabled(Action.reformatCode)) {
                    CommandProcessor.getInstance().runUndoTransparentAction(new Runnable() {

                                    .run();
                            }
                            if (storage.isEnabled(Action.reformatCode)) {

                }
            } else {
                saveFile(project, document, psiFile.getVirtualFile());
            }
        }
    }, project.getDisposed());
}

private static void makeProject(@NotNull final Project project) {
    ApplicationManager.getApplication().invokeLater(new Runnable() {

There's no direct function for this, but you can do it with a replace:

declare @myvar varchar(20)
set @myvar = 'Hello World'

select len(@myvar) - len(replace(@myvar,'o',''))

Basically this tells you how many chars were removed, and therefore how many instances of it there were.

Extra:

The above can be extended to count the occurences of a multi-char string by dividing by the length of the string being searched for. For example:

declare @myvar varchar(max), @tocount varchar(20)
set @myvar = 'Hello World, Hello World'
set @tocount = 'lo'

select (len(@myvar) - len(replace(@myvar,@tocount,''))) / LEN(@tocount)

I realize this may be a bit late, but I stumbled upon this and was wondering how to handle situations with multiple identical values, but different keys (as per bigbearzhu's comment).

So I modified Stephan Muller's answer slightly:

A datalist with non-unique values:

<input list="answers" name="answer" id="answerInput">
<datalist id="answers">
  <option value="42">The answer</option>
  <option value="43">The answer</option>
  <option value="44">Another Answer</option>
</datalist>
<input type="hidden" name="answer" id="answerInput-hidden">

When the user selects an option, the browser replaces input.value with the value of the datalist option instead of the innerText.

The following code then checks for an option with that value, pushes that into the hidden field and replaces the input.value with the innerText.

document.querySelector('#answerInput').addEventListener('input', function(e) {
    var input = e.target,   
        list = input.getAttribute('list'),
        options = document.querySelectorAll('#' + list + ' option[value="'+input.value+'"]'),
        hiddenInput = document.getElementById(input.getAttribute('id') + '-hidden');

    if (options.length > 0) {
      hiddenInput.value = input.value;
      input.value = options[0].innerText;
      }

});

As a consequence the user sees whatever the option's innerText says, but the unique id from option.value is available upon form submit. Demo jsFiddle

I had similar kind of problem while I was adding spring security dependency to my project , then I deleted my target folder and used maven update again . It's worked for me.

Something neat...

I wanted to look up an "Exact Town ID" based on a "Partial Exact Town Name" BUT although I had the entire town name I was searching against a list of Partial town names. So I First found the "Exact Town Name" based on the part (which was actually a partial name since the "master list" is partial names unfortunately)... THEN searched for the "Exact Town ID" based on that Exact town name SO all my Vlookups/Index/Match-whatevers....were set to EXACT ....

=INDEX(county_cheatsheet!$E$1:$E$516,MATCH(VLOOKUP(LEFT(D3,3)&"*",county_cheatsheet!$E$1:$E$516,1,FALSE),county_cheatsheet!$E$1:E$516,0))

The lookup of the "first three letters of the partial town name against the list of partial town names is the MATCH(VLOOKUP(LEFT(D3,3)&"*" part

Yes :). Try this:

DECLARE @text AS NVARCHAR(10)

SET @text = '100'
SELECT CASE WHEN ISNUMERIC(@text) = 1 THEN CAST(@text AS INT) ELSE NULL END
-- returns 100

SET @text = 'XXX'
SELECT CASE WHEN ISNUMERIC(@text) = 1 THEN CAST(@text AS INT) ELSE NULL END
-- returns NULL

ISNUMERIC() has a few issues pointed by Fedor Hajdu.

It returns true for strings like $ (is currency), , or . (both are separators), + and -.

I know its late but i recently ran into this situation. After wasting entire day I finally found the solution. I am suprised that I got this info on oracle's website whereas this seems nowhere to be found on IBM's website.

If you want to use JDBC drivers for DB2 that are compatible with JDK 1.5 or 1.4 , you need to use the jar db2jcc.jar, which is available in SQLLIB/java/ folder of your db2 installation.

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

Try the native Set type, for instance:

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

There is a refresh all option in the Pivot Table tool bar. That is enough. Dont have to do anything else.

Press ctrl+alt+F5

Here is a faster-than-grep AWK alternative way of doing this, which handles multiple matches of <url> per line, within a collection of XML files in a directory:

awk '/<url>/{m=gsub("<url>","");total+=m}END{print total}' some_directory/*.xml

This works well in cases where some XML files don't have line breaks.

Update MyTable
Set Value = (
                Select Min( T2.Value )
                From MyTable As T2
                Where T2.Id <> MyTable.Id
                    And T2.Name = MyTable.Name
                )
Where ( Value Is Null Or Value = '' )
    And Exists  (
                Select 1
                From MyTable As T3
                Where T3.Id <> MyTable.Id
                    And T3.Name = MyTable.Name
                )

Recently I have run into the same issue. And it was resolved using the following code:

x = new Date();
let hoursDiff = x.getHours() - x.getTimezoneOffset() / 60;
let minutesDiff = (x.getHours() - x.getTimezoneOffset()) % 60;
x.setHours(hoursDiff);
x.setMinutes(minutesDiff);

A keystore needs a keystore file. The KeyStore class needs a FileInputStream. But if you supply null (instead of FileInputStream instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool.

Following code creates an empty keystore with empty password

  KeyStore ks2 = KeyStore.getInstance("jks");
  ks2.load(null,"".toCharArray());
  FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore");
  ks2.store(out, "".toCharArray());

Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

This can be achieved by

<input type="file" accept="image/*" /> 

But this is not a good way. you have to code on the server side to check the file an image or not.

Check if image file is an actual image or fake image

if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    }
    else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}

Using

mapper.configure(
    JsonReadFeature.ALLOW_UNESCAPED_CONTROL_CHARS.mappedFeature(), 
    true
);

See javadoc:

/**
 * Feature that determines whether parser will allow
 * JSON Strings to contain unescaped control characters
 * (ASCII characters with value less than 32, including
 * tab and line feed characters) or not.
 * If feature is set false, an exception is thrown if such a
 * character is encountered.
 *<p>
 * Since JSON specification requires quoting for all control characters,
 * this is a non-standard feature, and as such disabled by default.
 */

Old option JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS was deprecated since 2.10.

Please see also github thread.

In my case, the problem was the optional parameter indicator('?') missing in my template configuration.

For example:

.when('/abc/:id?', {
    templateUrl: 'views/abc.html',
    controller: 'abcControl'
})


$location.path('/abc');

Without the interrogation character the route obviously would not change suppressing the route parameter.

this is a good sample for understand directive phases http://codepen.io/anon/pen/oXMdBQ?editors=101

var app = angular.module('myapp', [])

app.directive('slngStylePrelink', function() {

        scope: {
            drctvName: '@'
        },
        controller: function($scope) {
            console.log('controller for ', $scope.drctvName);
        },
        compile: function(element, attr) {
            console.log("compile for ", attr.name)

 $(function(){

        var xml = '<?xml version="1.0"?><foo><bar>bar</bar></foo>'; 

        var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async="false";
        xmlDoc.loadXML(xml);

        alert(xmlDoc.xml);

    });

Then push xmlDoc.xml to your java code.

My solution when I hit the quotes issue was to strip carriage returns from the end of my cells' text. Because of these carriage returns (inserted by an external program), Excel was adding quotes to the entire string.

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

1) I am sure there is no difference speedwise, both use FileInputStream internally and buffering

2) You can take measurements and see for yourself

3) Though there's no performance benefits I like the 1.7 approach

try (BufferedReader br = Files.newBufferedReader(Paths.get("test.txt"), StandardCharsets.UTF_8)) {
    for (String line = null; (line = br.readLine()) != null;) {
        //
    }
}

4) Scanner based version

    try (Scanner sc = new Scanner(new File("test.txt"), "UTF-8")) {
        while (sc.hasNextLine()) {
            String line = sc.nextLine();
        }
        // note that Scanner suppresses exceptions
        if (sc.ioException() != null) {
            throw sc.ioException();
        }
    }

5) This may be faster than the rest

try (SeekableByteChannel ch = Files.newByteChannel(Paths.get("test.txt"))) {
    ByteBuffer bb = ByteBuffer.allocateDirect(1000);
    for(;;) {
        StringBuilder line = new StringBuilder();
        int n = ch.read(bb);
        // add chars to line
        // ...
    }
}

it requires a bit of coding but it can be really faster because of ByteBuffer.allocateDirect. It allows OS to read bytes from file to ByteBuffer directly, without copying

6) Parallel processing would definitely increase speed. Make a big byte buffer, run several tasks that read bytes from file into that buffer in parallel, when ready find first end of line, make a String, find next...

Maybe the best idea is to solve the problem while the data is in String format. If you have the data as String, you may parse it according to the decimal point. You extract the integral and decimal part as Substrings and then convert these substrings to actual integers.

Use the Count property. The last index will be Count - 1.

for (int cnt3 = 0 ; cnt3 < integerList.Count; cnt3++)

Joe's approach is actually the most effective means that I have found for doing this conversation. To elaborate a little bit more on it, you should right click on the project in the package explorer in eclipse and then select to delete it without removing directory or its contents. Next, you select to create a Java project (File -> New -> Java Project) and in the Contents part of the New Java Project dialog box, select 'Create project from existing source'.

The advantage this approach is that source folders will be properly identified. I found that mucking around with the .project file can lead to the entire directory being considered a source folder which is not what you want.

try this:

for (char c: string.toCharArray()){
  if (((int)c)>127){
    return false;
  } 
}
return true;

The functionality you're looking for can be achieved through the use of the "defineProperty()" method--which is only available to modern browsers:

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

I've written a jQuery extension that has some similar functionality if you need more cross browser support:

https://github.com/jarederaj/jQueue

A small jQuery extension that handles queuing callbacks to the existence of a variable, object, or key. You can assign any number of callbacks to any number of data points that might be affected by processes running in the background. jQueue listens and waits for these data you specify to come into existence and then fires off the correct callback with its arguments.

You could probably detect inactivity on your web page using the mousemove tricks listed, but that won't tell you that the user isn't on another page in another window or tab, or that the user is in Word or Photoshop, or WOW and just isn't looking at your page at this time. Generally I'd just do the prefetch and rely on the client's multi-tasking. If you really need this functionality you do something with an activex control in windows, but it's ugly at best.

For ASCII characters in the range [ -~] on Python 2:

>>> import binascii
>>> bin(int(binascii.hexlify('hello'), 16))
'0b110100001100101011011000110110001101111'

In reverse:

>>> n = int('0b110100001100101011011000110110001101111', 2)
>>> binascii.unhexlify('%x' % n)
'hello'

In Python 3.2+:

>>> bin(int.from_bytes('hello'.encode(), 'big'))
'0b110100001100101011011000110110001101111'

In reverse:

>>> n = int('0b110100001100101011011000110110001101111', 2)
>>> n.to_bytes((n.bit_length() + 7) // 8, 'big').decode()
'hello'

To support all Unicode characters in Python 3:

def text_to_bits(text, encoding='utf-8', errors='surrogatepass'):
    bits = bin(int.from_bytes(text.encode(encoding, errors), 'big'))[2:]
    return bits.zfill(8 * ((len(bits) + 7) // 8))

def text_from_bits(bits, encoding='utf-8', errors='surrogatepass'):
    n = int(bits, 2)
    return n.to_bytes((n.bit_length() + 7) // 8, 'big').decode(encoding, errors) or '\0'

Here's single-source Python 2/3 compatible version:

import binascii

def text_to_bits(text, encoding='utf-8', errors='surrogatepass'):
    bits = bin(int(binascii.hexlify(text.encode(encoding, errors)), 16))[2:]
    return bits.zfill(8 * ((len(bits) + 7) // 8))

def text_from_bits(bits, encoding='utf-8', errors='surrogatepass'):
    n = int(bits, 2)
    return int2bytes(n).decode(encoding, errors)

def int2bytes(i):
    hex_string = '%x' % i
    n = len(hex_string)
    return binascii.unhexlify(hex_string.zfill(n + (n & 1)))

Example

>>> text_to_bits('hello')
'0110100001100101011011000110110001101111'
>>> text_from_bits('110100001100101011011000110110001101111') == u'hello'
True

To communicate a child component with another child component I've made a method in parent which calls a method in a child with:

this.$refs.childMethod()

And from the another child I've called the root method:

this.$root.theRootMethod()

It worked for me.

For those who don't want to remember the syntax everytime here is a simple encapsulation:

public class FileDialogFilter : List<string>
{
    public string Explanation { get; }

    public FileDialogFilter(string explanation, params string[] extensions)
    {
        Explanation = explanation;
        AddRange(extensions);
    }

    public string GetFileDialogRepresentation()
    {
        if (!this.Any())
        {
            throw new ArgumentException("No file extension is defined.");
        }

        StringBuilder builder = new StringBuilder();

        builder.Append(Explanation);

        builder.Append(" (");
        builder.Append(String.Join(", ", this));
        builder.Append(")");

        builder.Append("|");
        builder.Append(String.Join(";", this));

        return builder.ToString();
    }
}

public class FileDialogFilterCollection : List<FileDialogFilter>
{
    public string GetFileDialogRepresentation()
    {
        return String.Join("|", this.Select(filter => filter.GetFileDialogRepresentation()));
    }
}

Usage:

FileDialogFilter filterImage = new FileDialogFilter("Image Files", "*.jpeg", "*.bmp");
FileDialogFilter filterOffice = new FileDialogFilter("Office Files", "*.doc", "*.xls", "*.ppt");

FileDialogFilterCollection filters = new FileDialogFilterCollection
{
    filterImage,
    filterOffice
};

OpenFileDialog fileDialog = new OpenFileDialog
{
    Filter = filters.GetFileDialogRepresentation()
};

fileDialog.ShowDialog();

site-packages is just the location where Python installs its modules.

No need to "find it", python knows where to find it by itself, this location is always part of the PYTHONPATH (sys.path).

Programmatically you can find it this way:

import sys
site_packages = next(p for p in sys.path if 'site-packages' in p)
print site_packages

'/Users/foo/.envs/env1/lib/python2.7/site-packages'

Programmatialy:

You can do programmatically using setTypeface() method:

Below is the code for default Typeface

textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
textView.setTypeface(null, Typeface.BOLD);        // for Bold only
textView.setTypeface(null, Typeface.ITALIC);      // for Italic
textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic

and if you want to set custom Typeface:

textView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      // for Normal Text
textView.setTypeface(textView.getTypeface(), Typeface.BOLD);        // for Bold only
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      // for Italic
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC); // for Bold and Italic

XML:

You can set Directly in XML file in like:

android:textStyle="normal"
android:textStyle="normal|bold"
android:textStyle="normal|italic"
android:textStyle="bold"
android:textStyle="bold|italic"

Just stumbled upon this and thought I would suggest my solution. I typically like to use the built in functionality of assigning a range to an multi-dim array (I guess it's also the JS Programmer in me).

I frequently write code like this:

Sub arrayBuilder()

myarray = Range("A1:D4")

'unlike most VBA Arrays, this array doesn't need to be declared and will be automatically dimensioned

For i = 1 To UBound(myarray)

    For j = 1 To UBound(myarray, 2)

    Debug.Print (myarray(i, j))

    Next j

Next i

End Sub

Assigning ranges to variables is a very powerful way to manipulate data in VBA.

It's not an insert if the record already exists in t1 (the user_id matches) unless you are happy to create duplicate user_id's.

You might want an update?

UPDATE t1
   SET <t1.col_list> = (SELECT <t2.col_list>
                          FROM t2
                         WHERE t2.user_id = t1.user_id)
 WHERE EXISTS
      (SELECT 1
         FROM t2
        WHERE t1.user_id = t2.user_id);

Hope it helps...

See populate a database in the PostgreSQL manual, depesz's excellent-as-usual article on the topic, and this SO question.

(Note that this answer is about bulk-loading data into an existing DB or to create a new one. If you're interested DB restore performance with pg_restore or psql execution of pg_dump output, much of this doesn't apply since pg_dump and pg_restore already do things like creating triggers and indexes after it finishes a schema+data restore).

There's lots to be done. The ideal solution would be to import into an UNLOGGED table without indexes, then change it to logged and add the indexes. Unfortunately in PostgreSQL 9.4 there's no support for changing tables from UNLOGGED to logged. 9.5 adds ALTER TABLE ... SET LOGGED to permit you to do this.

If you can take your database offline for the bulk import, use pg_bulkload.

Otherwise:

• Disable any triggers on the table

• Drop indexes before starting the import, re-create them afterwards. (It takes much less time to build an index in one pass than it does to add the same data to it progressively, and the resulting index is much more compact).

• If doing the import within a single transaction, it's safe to drop foreign key constraints, do the import, and re-create the constraints before committing. Do not do this if the import is split across multiple transactions as you might introduce invalid data.

• If possible, use COPY instead of INSERTs

• If you can't use COPY consider using multi-valued INSERTs if practical. You seem to be doing this already. Don't try to list too many values in a single VALUES though; those values have to fit in memory a couple of times over, so keep it to a few hundred per statement.

• Batch your inserts into explicit transactions, doing hundreds of thousands or millions of inserts per transaction. There's no practical limit AFAIK, but batching will let you recover from an error by marking the start of each batch in your input data. Again, you seem to be doing this already.

• Use synchronous_commit=off and a huge commit_delay to reduce fsync() costs. This won't help much if you've batched your work into big transactions, though.

• INSERT or COPY in parallel from several connections. How many depends on your hardware's disk subsystem; as a rule of thumb, you want one connection per physical hard drive if using direct attached storage.

• Set a high checkpoint_segments value and enable log_checkpoints. Look at the PostgreSQL logs and make sure it's not complaining about checkpoints occurring too frequently.

• If and only if you don't mind losing your entire PostgreSQL cluster (your database and any others on the same cluster) to catastrophic corruption if the system crashes during the import, you can stop Pg, set fsync=off, start Pg, do your import, then (vitally) stop Pg and set fsync=on again. See WAL configuration. Do not do this if there is already any data you care about in any database on your PostgreSQL install. If you set fsync=off you can also set full_page_writes=off; again, just remember to turn it back on after your import to prevent database corruption and data loss. See non-durable settings in the Pg manual.

You should also look at tuning your system:

• Use good quality SSDs for storage as much as possible. Good SSDs with reliable, power-protected write-back caches make commit rates incredibly faster. They're less beneficial when you follow the advice above - which reduces disk flushes / number of fsync()s - but can still be a big help. Do not use cheap SSDs without proper power-failure protection unless you don't care about keeping your data.

• If you're using RAID 5 or RAID 6 for direct attached storage, stop now. Back your data up, restructure your RAID array to RAID 10, and try again. RAID 5/6 are hopeless for bulk write performance - though a good RAID controller with a big cache can help.

• If you have the option of using a hardware RAID controller with a big battery-backed write-back cache this can really improve write performance for workloads with lots of commits. It doesn't help as much if you're using async commit with a commit_delay or if you're doing fewer big transactions during bulk loading.

• If possible, store WAL (pg_xlog) on a separate disk / disk array. There's little point in using a separate filesystem on the same disk. People often choose to use a RAID1 pair for WAL. Again, this has more effect on systems with high commit rates, and it has little effect if you're using an unlogged table as the data load target.

You have an orphaned user and this can't be remapped with ALTER USER (yet) becauses there is no login to map to. So, you need run CREATE LOGIN first.

If the database level user is

• a Windows Login, the mapping will be fixed automatcially via the AD SID
• a SQL Login, use "sid" from sys.database_principals for the SID option for the login

Then run ALTER USER

Edit, after comments and updates

The sid from sys.database_principals is for a Windows login.

So trying to create and re-map to a SQL Login will fail

Run this to get the Windows login

SELECT SUSER_SNAME(0x0105000000000009030000001139F53436663A4CA5B9D5D067A02390)

Simple:

byte[] data = Convert.FromBase64String(encodedString);
string decodedString = Encoding.UTF8.GetString(data);

With Java 8:

String csv = String.join(",", ids);

With Java 7-, there is a dirty way (note: it works only if you don't insert strings which contain ", " in your list) - obviously, List#toString will perform a loop to create idList but it does not appear in your code:

List<String> ids = new ArrayList<String>();
ids.add("1");
ids.add("2");
ids.add("3");
ids.add("4");
String idList = ids.toString();
String csv = idList.substring(1, idList.length() - 1).replace(", ", ",");

bool is an alias for System.Boolean just as int is an alias for System.Int32. See a full list of aliases here: Built-In Types Table (C# Reference).

How about mkString ?

theStrings.mkString(",")

A variant exists in which you can specify a prefix and suffix too.

See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.

This is because you have the following code:

class JSONDeserializer
{
    Value JSONDeserializer::ParseValue(TDR type, const json_string& valueString);
};

This is not valid C++ but Visual Studio seems to accept it. You need to change it to the following code to be able to compile it with a standard compliant compiler (gcc is more compliant to the standard on this point).

class JSONDeserializer
{
    Value ParseValue(TDR type, const json_string& valueString);
};

The error come from the fact that JSONDeserializer::ParseValue is a qualified name (a name with a namespace qualification), and such a name is forbidden as a method name in a class.

adb shell am broadcast -a android.intent.action.xxx

Mention xxx as the action that you mentioned in the manifest file.

I compared each of method that each answer mentioned. At this moment I use python 3.6.3 for this implementation. This is the code that I have used:

import time
import random
from decimal import Decimal


def method1():
    common_elements = [x for x in li1_temp if x in li2_temp]
     print(len(common_elements))


def method2():
    common_elements = (x for x in li1_temp if x in li2_temp)
    print(len(list(common_elements)))


def method3():
    common_elements = set(li1_temp) & set(li2_temp)
    print(len(common_elements))


def method4():
    common_elements = set(li1_temp).intersection(li2_temp)
    print(len(common_elements))


if __name__ == "__main__":
    li1 = []
    li2 = []
    for i in range(100000):
        li1.append(random.randint(0, 10000))
        li2.append(random.randint(0, 10000))

    li1_temp = list(set(li1))
    li2_temp = list(set(li2))

    methods = [method1, method2, method3, method4]
    for m in methods:
        start = time.perf_counter()
        m()
        end = time.perf_counter()
        print(Decimal((end - start)))

If you run this code you can see that if you use list or generator(if you iterate over generator, not just use it. I did this when I forced generator to print length of it), you get nearly same performance. But if you use set you get much better performance. Also if you use intersection method you will get a little bit better performance. the result of each method in my computer is listed bellow:

1. method1: 0.8150673999999999974619413478649221360683441
2. method2: 0.8329545000000001531148541289439890533685684
3. method3: 0.0016547000000000089414697868051007390022277
4. method4: 0.0010262999999999244948867271887138485908508

Try this:

#wrapper {
    text-align: center;
}

#wrapper iframe {
    display: inline-block;
}

Be sure to have both objects created in controller: @post and @comment for the post, eg:

@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)

Then in view:

<%= form_for([@post, @comment]) do |f| %>

Be sure to explicitly define the array in the form_for, not just comma separated like you have above.

I would just loop through your JRadioButtons and call isSelected(). If you really want to go from the ButtonGroup you can only get to the models. You could match the models to the buttons, but then if you have access to the buttons, why not use them directly?

Assuming your controller's action method is something like this:

public ActionResult AllCategories(int id = 0)
{
    return View(db.Categories.Include(p => p.Products).ToList());
}

Modify your models to be something like this:

public class Product
{
    [Key]
    public int ID { get; set; }
    public int CategoryID { get; set; }
    //new code
    public virtual Category Category { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    public string Path { get; set; }

    //remove code below
    //public virtual ICollection<Category> Categories { get; set; }
}

public class Category
{
    [Key]
    public int CategoryID { get; set; }
    public string Name { get; set; }
    //new code
    public virtual ICollection<Product> Products{ get; set; }
}

Then your since now the controller takes in a Category as Model (instead of a Product):

foreach (var category in Model)
{
    <h3><u>@category.Name</u></h3>
    <div>
        <ul>    
            @foreach (var product in Model.Products)
            {
                // cut for brevity, need to add back more code from original
                <li>@product.Title</li>
            }
        </ul>
    </div>
}

UPDATED: Add ToList() to the controller return statement.

The best loading and blocking that particular div for ajax call until it succeeded is Blockui

go through this link http://www.malsup.com/jquery/block/#element

example usage:

 <span class="no-display smallLoader"><img src="/images/loader-small.png" /></span>

script

jQuery.ajax(
{   
 url: site_path+"/restaurantlist/addtocart",
 type: "POST",
 success: function (data) {
   jQuery("#id").unblock(); 
},
beforeSend:function (data){
    jQuery("#id").block({ 
    message: jQuery(".smallLoader").html(), 
    css: { 
         border: 'none', 
         backgroundColor: 'none'
    },
    overlayCSS: { backgroundColor: '#afafaf' } 
    });

}
});

hope this helps really it is very interactive.

If c is a set then you can check whether it's empty by doing: return not c.

If c is empty then not c will be True.

Otherwise, if c contains any elements not c will be False.

import tarfile
tar = tarfile.open("sample.tar.gz", "w:gz")
for name in ["file1", "file2", "file3"]:
    tar.add(name)
tar.close()

If you want to create a tar.bz2 compressed file, just replace file extension name with ".tar.bz2" and "w:gz" with "w:bz2".

You can use git filter-branch for that. e.g.

git filter-branch --parent-filter \
'if test $GIT_COMMIT != <sha1ofB>; then cat; fi'

This results in AB-C throwing away the commit log of A.

You will need to pad with "0" if its a single digit & note getMonth returns 0..11 not 1..12

function printDate() {
    var temp = new Date();
    var dateStr = padStr(temp.getFullYear()) +
                  padStr(1 + temp.getMonth()) +
                  padStr(temp.getDate()) +
                  padStr(temp.getHours()) +
                  padStr(temp.getMinutes()) +
                  padStr(temp.getSeconds());
    debug (dateStr );
}

function padStr(i) {
    return (i < 10) ? "0" + i : "" + i;
}

I had a similar problem after updating my VS2017. Project built fine; but lots of 'errors' when code was brought up in the editor. Even tried reinstalling VS. I was able to solve it by setting the option “Ignore Standard Include Paths” to Yes. Attempted to build the solution with lots of errors. Went back and set the option to No. After rebuilding, my problem went away.

Normally, Spring should do the autowiring, as long as your abstract class is in the base-package provided for component scan.

See this and this for further reference.

@Service and @Component are both stereotypes that creates beans of the annotated type inside the Spring container. As Spring Docs state,

This annotation serves as a specialization of @Component, allowing for implementation classes to be autodetected through classpath scanning.

It could just be because ACID is one set of properties that substances show( in Chemistry) and BASE is a complement set of them.So it could be just to show the contrast between the two that the acronym was made up and then 'Basically Available Soft State Eventual Consistency' was decided as it's full-form.

As a workaround:

Runtime.exec(...)

returns an Object of type

java.lang.Process

The Process class is abstract, and what you get back is some subclass of Process which is designed for your operating system. For example on Macs, it returns java.lang.UnixProcess which has a private field called pid. Using Reflection you can easily get the value of this field. This is admittedly a hack, but it might help. What do you need the PID for anyway?

I agree with the answers 1 and 2. However, I prefer to specify each library separately. This makes the depencencies clearer in big projects. Yet, there is the danger of mistyping the (case-sensitive) variable names. In that case there is no direct cmake error but some undefined references linker issues later on, which may take some time to resolve. Therefore I use the following cmake function:

function(VerifyVarDefined)
  foreach(lib ${ARGV}) 
    if(DEFINED ${lib})
    else(DEFINED ${lib})
      message(SEND_ERROR "Variable ${lib} is not defined")
    endif(DEFINED ${lib})
  endforeach()
endfunction(VerifyVarDefined)

For the example mentioned above, this looks like:

VerifyVarDefined(Boost_PROGRAM_OPTIONS_LIBRARY Boost_REGEX_LIBRARY)
target_link_libraries( run ${Boost_PROGRAM_OPTIONS_LIBRARY} ${Boost_REGEX_LIBRARY} )

If I had written "BOOST_PROGRAM_OPTIONS_LIBRARY" there would have been an error triggered by cmake and not much later triggered by the linker.

For Xamarin Android align to the left of an object

int dp24 = (int)TypedValue.ApplyDimension( ComplexUnitType.Dip, 24, Resources.System.DisplayMetrics );
            RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( dp24, dp24 );
            lp.AddRule( LayoutRules.CenterInParent, 1 );
            lp.AddRule( LayoutRules.LeftOf, //Id of the field Eg m_Button.Id ); 
            m_Button.LayoutParameters = lp;

Database is a collection of schemas and schema is a collection of tables. But in MySQL they use it the same way.

To get the path of file in application package;

ContextWrapper c = new ContextWrapper(this);
Toast.makeText(this, c.getFilesDir().getPath(), Toast.LENGTH_LONG).show();

String upToNCharacters = String.format("%."+ n +"s", str);

Awful if n is a variable (so you must construct the format string), but pretty clear if a constant:

String upToNCharacters = String.format("%.10s", str);

ULs don't have a name attribute, but you can reference the ul by tag name.

Try replacing line 3 in your script with this:

var sub = cat.getElementsByTagName("UL");

If you're on Windows:

Go to your php.ini file and remove the ; mark from the beginning of the following line:

;extension=php_curl.dll

After you have saved the file you must restart your HTTP server software (e.g. Apache) before this can take effect.

For Ubuntu 13.0 and above, simply use the debundled package. In a terminal type the following to install it and do not forgot to restart server.

sudo apt-get install php-curl

Or if you're using the old PHP5

sudo apt-get install php5-curl

or

sudo apt-get install php5.6-curl

Then restart apache to activate the package with

sudo service apache2 restart

Since I have to reuse this few time, I came up with this class that simply help to abstract how the query string is composed.

public class UriBuilderExt
{
    private NameValueCollection collection;
    private UriBuilder builder;

    public UriBuilderExt(string uri)
    {
        builder = new UriBuilder(uri);
        collection = System.Web.HttpUtility.ParseQueryString(string.Empty);
    }

    public void AddParameter(string key, string value) {
        collection.Add(key, value);
    }

    public Uri Uri{
        get
        {
            builder.Query = collection.ToString();
            return builder.Uri;
        }
    }

}

The use will be simplify to something like this:

var builder = new UriBuilderExt("http://example.com/");
builder.AddParameter("foo", "bar<>&-baz");
builder.AddParameter("bar", "second");
var uri = builder.Uri;

that will return the uri: http://example.com/?foo=bar%3c%3e%26-baz&bar=second

May be it's good if you define your background-image in the :after pseudo class. Write like this:

.parent{
    width:300px;
    height:300px;
    position:relative;
    border:1px solid red;
}
.parent:after{
    content:'';
    background:url('http://www.dummyimage.com/300x300/000/fff&text=parent+image');
    width:300px;
    height:300px;
    position:absolute;
    top:0;
    left:0;
    opacity:0.5;
}
.child{
    background:yellow;
    position:relative;
    z-index:1;
}

Here seems to be an even better answer with 'in' clause that allows for multiple keys for the join:

update fp_active set STATE='E', 
   LAST_DATE_MAJ = sysdate where (client,code) in (select (client,code) from fp_detail
  where valid = 1) ...

The full example is here: http://forums.devshed.com/oracle-development-96/how-to-update-from-two-tables-195893.html - from web archive since link was dead.

The beef is in having the columns that you want to use as the key in parentheses in the where clause before 'in' and have the select statement with the same column names in parentheses. where (column1,column2) in ( select (column1,column2) from table where "the set I want" );

I recommend not using WebClient.DownloadString. This is because (at least in .NET 3.5) DownloadString is not smart enough to use/remove the BOM, should it be present. This can result in the BOM () incorrectly appearing as part of the string when UTF-8 data is returned (at least without a charset) - ick!

Instead, this slight variation will work correctly with BOMs:

string ReadTextFromUrl(string url) {
    // WebClient is still convenient
    // Assume UTF8, but detect BOM - could also honor response charset I suppose
    using (var client = new WebClient())
    using (var stream = client.OpenRead(url))
    using (var textReader = new StreamReader(stream, Encoding.UTF8, true)) {
        return textReader.ReadToEnd();
    }
}

Set the height of the text view android:minHeight="some pixes" or android:width="some pixels". It will solve the problem.

Solution with utl_encode.base64_encode and utl_encode.base64_decode have one limitation, they work only with strings up to 32,767 characters/bytes.

In case you have to convert bigger strings you will face several obstacles.

• For BASE64_ENCODE the function has to read 3 Bytes and transform them. In case of Multi-Byte characters (e.g. öäüè€ stored at UTF-8, aka AL32UTF8) 3 Character are not necessarily also 3 Bytes. In order to read always 3 Bytes you have to convert your CLOB into BLOB first.
• The same problem applies for BASE64_DECODE. The function has to read 4 Bytes and transform them into 3 Bytes. Those 3 Bytes are not necessarily also 3 Characters
• Typically a BASE64-String has NEW_LINE (CR and/or LF) character each 64 characters. Such new-line characters have to be ignored while decoding.

Taking all this into consideration the full featured solution could be this one:

    buffer RAW(1440);

    -- BASE64 characters are always simple ASCII. Thus you get never any Mulit-Byte character and having the same size as 'amount' is sufficient

BEGIN

This is just a WAG as I am not a Subclipse user, but have you ensured that the folders containing what you're trying to ignore have themselves been added to SVN? You can't svn:ignore something inside a folder that's not under version control.

Some CSS :

table td, table td * {
    vertical-align: top;
}

You could just write to the file as you would write any normal file.

with open('csvfile.csv','wb') as file:
    for l in text:
        file.write(l)
        file.write('\n')

If just in case, it is a list of lists, you could directly use built-in csv module

import csv

with open("csvfile.csv", "wb") as file:
    writer = csv.writer(file)
    writer.writerows(text)

A note for others who may be using Owl Carousel v 1.3.2:

You can replace the navigation text in the settings where you're enabling the navigation.

navigation:true,
navigationText: [

   "<i class='fa fa-chevron-right'></i>"
]

I have same problem, and solve by this way:

1. Open CMD
2. Go to file netbeans.exe
3. Press Shift Key + Right Click and copy as path Copy as path
4. Paste on CMD look like C:\Users\unnamed>"C:\Users\unnamed\Downloads\Programs\netbeans-8.2-windows.exe"
5. Write --javahome do same point 2 on JDK folder

6. Write on cmd look like C:\Users\unnamed>"C:\Users\unnamed\Downloads\Programs\netbeans-8.2-windows.exe" --javahome "C:\Program Files\Java\jdk-9.0.4"

7. Enter. Enjoy it.

You can redirect stdout into a file "output.txt":

import sys
sys.stdout = open('output.txt','wt')
print ("Hello stackoverflow!")
print ("I have a question.")

Check that the port that SQL Server is using is not being blocked by either your firewall or the VPN.

1.

long date = curDateFld.getDate();
//convert long to string
String str = String.valueOf(date);

//convert string to long
date = Long.valueOf(str);

2.

 //convert long to string just concat long with empty string
 String str = ""+date;
//convert string to long

date = Long.valueOf(str);

There are several possible answers here. You want to return something that might exist. Here are some options, ranging from my least preferred to most preferred:

• Return by reference, and signal can-not-find by exception.

  Attr& getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return attributes[i];
     //if not found
          throw no_such_attribute_error;
  }

It's likely that not finding attributes is a normal part of execution, and hence not very exceptional. The handling for this would be noisy. A null value cannot be returned because it's undefined behaviour to have null references.

• Return by pointer

  Attr* getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return &attributes[i];
     //if not found
          return nullptr;
  }

It's easy to forget to check whether a result from getAttribute would be a non-NULL pointer, and is an easy source of bugs.

• Use Boost.Optional

  boost::optional<Attr&> getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return attributes[i];
     //if not found
          return boost::optional<Attr&>();
  }

A boost::optional signifies exactly what is going on here, and has easy methods for inspecting whether such an attribute was found.

Side note: std::optional was recently voted into C++17, so this will be a "standard" thing in the near future.

Generally you can just cast the variable to become a short.

You can also get problems like this that can be confusing. This is because the + operator promotes them to an int

Casting the elements won't help:

You need to cast the expression:

try {
    Import-Module SomeModule
    Write-Host "Module exists"
} 
catch {
    Write-Host "Module does not exist"
}

It should be pointed out that your cmdlet Import-Module has no terminating error, therefore the exception isnt being caught so no matter what your catch statement will never return the new statement you have written.

(https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_try_catch_finally?view=powershell-6

From The Above:

"A terminating error stops a statement from running. If PowerShell does not handle a terminating error in some way, PowerShell also stops running the function or script using the current pipeline. In other languages, such as C#, terminating errors are referred to as exceptions. For more information about errors, see about_Errors."

It should be written as:

Try {
    Import-Module SomeModule -Force -Erroraction stop
    Write-Host "yep"
}
Catch {
    Write-Host "nope"
}

Which returns:

nope

And if you really wanted to be thorough you should add in the other suggested cmdlets Get-Module -ListAvailable -Name and Get-Module -Name to be extra cautious, before running other functions/cmdlets. And if its installed from psgallery or elsewhere you could also run a Find-Module cmdlet to see if there is a new version available.

For some unexplained reason this solution doesn't work for me (maybe some incompatibility of types), so I came up with a solution for myself:

HttpResponseMessage response = await client.GetAsync("api/yourcustomobjects");
if (response.IsSuccessStatusCode)
{
    var data = await response.Content.ReadAsStringAsync();
    var product = JsonConvert.DeserializeObject<Product>(data);
}

This way my content is parsed into a JSON string and then I convert it to my object.

delete it from eclipse......u might have closed the project in eclipse by "(Rightclick)-->close project".....so even if you delete this project from workspace folder....it stays there in eclipse IDE as closed project.....you should delete it from Eclipse IDE...!!!

For MAC users:

1. Open terminal

cd ~

2. Double check the $PATH

echo $PATH

3. Edit file

nano ~/.bash_profile

4. PASTE

export PATH="~/.composer/vendor/bin:$PATH"

Don't forget to put quotation marks.

5. control + X (y + enter to save the file and exit)

Now start vagrant, go to your folder and try:

laravel new yourprojectname

syntax is:

sheet.addMergedRegion(new CellRangeAddress(start-col,end-col,start-cell,end-cell));

Example:

sheet.addMergedRegion(new CellRangeAddress(4, 4, 0, 5));

Here the cell 0 to cell 5 will be merged of the 4th row.

It must work. I used to debug a .exe file and a dll at the same time ! What I suggest is 1) Include the path of the dll in your B project, 2) Then compile in debug your A project 3) Control that the path points on the A dll and de pdb file.... 4)After that you start in debug the B project and if all is ok, you will be able to debug in both projects !

Kotlin Solution

The base way to handle it in Kotlin is:

edittext.setOnEditorActionListener { _, actionId, _ ->
    if (actionId == EditorInfo.IME_ACTION_DONE) {
        callback.invoke()
        true
    }
    false
}

Kotlin Extension

Use this to just call edittext.onDone{/*action*/} in your main code. Makes your code far more readable and maintainable

fun EditText.onDone(callback: () -> Unit) {
    setOnEditorActionListener { _, actionId, _ ->
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            callback.invoke()
            true
        }
        false
    }
}

Don't forget to add these options to your edittext

<EditText ...
    android:imeOptions="actionDone"
    android:inputType="text"/>

If you need inputType="textMultiLine" support, read this post

Depending on your workflow, you might want to look at strapdown

That's a fork of the original one (http://strapdownjs.com) that adds the generation of the table of content.

There's an apache config file on the repo (might not be properly updated yet) to wrap plain markdown on the fly, if you prefer not writing in html files.

For me, the following hack worked; Go to IIS -> Application Pools -> Advance Settings -> Process Model -> Identity Changed from Built-in Account (ApplicationPoolIdentity) to Custom Account (My Domain User)

Try below command:

Let's go in reverse order:

• Log.e: This is for when bad stuff happens. Use this tag in places like inside a catch statement. You know that an error has occurred and therefore you're logging an error.

• Log.w: Use this when you suspect something shady is going on. You may not be completely in full on error mode, but maybe you recovered from some unexpected behavior. Basically, use this to log stuff you didn't expect to happen but isn't necessarily an error. Kind of like a "hey, this happened, and it's weird, we should look into it."

• Log.i: Use this to post useful information to the log. For example: that you have successfully connected to a server. Basically use it to report successes.

• Log.d: Use this for debugging purposes. If you want to print out a bunch of messages so you can log the exact flow of your program, use this. If you want to keep a log of variable values, use this.

• Log.v: Use this when you want to go absolutely nuts with your logging. If for some reason you've decided to log every little thing in a particular part of your app, use the Log.v tag.

And as a bonus...

• Log.wtf: Use this when stuff goes absolutely, horribly, holy-crap wrong. You know those catch blocks where you're catching errors that you never should get...yeah, if you wanna log them use Log.wtf
