Programs & Examples On #Decorator

This answer has long been answered, but I thought I would share my Decorator class which makes writing new decorators easy and compact.

from abc import ABCMeta, abstractclassmethod

class Decorator(metaclass=ABCMeta):
    """ Acts as a base class for all decorators """

    def __init__(self):
        self.method = None

    def __call__(self, method):
        self.method = method
        return self.call

    @abstractclassmethod
    def call(self, *args, **kwargs):
        return self.method(*args, **kwargs)

For one I think this makes the behavior of decorators very clear, but it also makes it easy to define new decorators very concisely. For the example listed above, you could then solve it as:

class MakeBold(Decorator):
    def call():
        return "<b>" + self.method() + "</b>"

class MakeItalic(Decorator):
    def call():
        return "<i>" + self.method() + "</i>"

@MakeBold()
@MakeItalic()
def say():
   return "Hello"

You could also use it to do more complex tasks, like for instance a decorator which automatically makes the function get applied recursively to all arguments in an iterator:

class ApplyRecursive(Decorator):
    def __init__(self, *types):
        super().__init__()
        if not len(types):
            types = (dict, list, tuple, set)
        self._types = types

    def call(self, arg):
        if dict in self._types and isinstance(arg, dict):
            return {key: self.call(value) for key, value in arg.items()}

        if set in self._types and isinstance(arg, set):
            return set(self.call(value) for value in arg)

        if tuple in self._types and isinstance(arg, tuple):
            return tuple(self.call(value) for value in arg)

        if list in self._types and isinstance(arg, list):
            return list(self.call(value) for value in arg)

        return self.method(arg)


@ApplyRecursive(tuple, set, dict)
def double(arg):
    return 2*arg

print(double(1))
print(double({'a': 1, 'b': 2}))
print(double({1, 2, 3}))
print(double((1, 2, 3, 4)))
print(double([1, 2, 3, 4, 5]))

Which prints:

2
{'a': 2, 'b': 4}
{2, 4, 6}
(2, 4, 6, 8)
[1, 2, 3, 4, 5, 1, 2, 3, 4, 5]

Notice that this example didn't include the list type in the instantiation of the decorator, so in the final print statement the method gets applied to the list itself, not the elements of the list.

Here's an expansion on Michael Speer's answer to take it a few steps further:

An instance method decorator which takes arguments and acts on a function with arguments and a return value.

class Test(object):
    "Prints if x == y. Throws an error otherwise."
    def __init__(self, x):
        self.x = x

    def _outer_decorator(y):
        def _decorator(foo):
            def magic(self, *args, **kwargs) :
                print("start magic")
                if self.x == y:
                    return foo(self, *args, **kwargs)
                else:
                    raise ValueError("x ({}) != y ({})".format(self.x, y))
                print("end magic")
            return magic

        return _decorator

    @_outer_decorator(y=3)
    def bar(self, *args, **kwargs) :
        print("normal call")
        print("args: {}".format(args))
        print("kwargs: {}".format(kwargs))

        return 27

And then

In [2]:

    test = Test(3)
    test.bar(
        13,
        'Test',
        q=9,
        lollipop=[1,2,3]
    )
    ?
    start magic
    normal call
    args: (13, 'Test')
    kwargs: {'q': 9, 'lollipop': [1, 2, 3]}
Out[2]:
    27
In [3]:

    test = Test(4)
    test.bar(
        13,
        'Test',
        q=9,
        lollipop=[1,2,3]
    )
    ?
    start magic
    ---------------------------------------------------------------------------
    ValueError                                Traceback (most recent call last)

          7 )

    <ipython-input-1-428f22ac6c9b> in magic(self, *args, **kwargs)
         11                     return foo(self, *args, **kwargs)
         12                 else:
    ---> 13                     raise ValueError("x ({}) != y ({})".format(self.x, y))
         14                 print("end magic")
         15             return magic

    ValueError: x (4) != y (3)

This point is been cleared by many people up there but here is a direct point which I was searching. This is what I feel is important to start with the @property decorator. eg:-

class UtilityMixin():
    @property
    def get_config(self):
        return "This is property"

The calling of function "get_config()" will work like this.

util = UtilityMixin()
print(util.get_config)

If you notice I have not used "()" brackets for calling the function. This is the basic thing which I was searching for the @property decorator. So that you can use your function just like a variable.

In short, functools.wraps is just a regular function. Let's consider this official example. With the help of the source code, we can see more details about the implementation and the running steps as follows:

1. wraps(f) returns an object, say O1. It is an object of the class Partial
2. The next step is @O1... which is the decorator notation in python. It means

wrapper=O1.__call__(wrapper)

Checking the implementation of __call__, we see that after this step, (the left hand side )wrapper becomes the object resulted by self.func(*self.args, *args, **newkeywords) Checking the creation of O1 in __new__, we know self.func is the function update_wrapper. It uses the parameter *args, the right hand side wrapper, as its 1st parameter. Checking the last step of update_wrapper, one can see the right hand side wrapper is returned, with some of attributes modified as needed.

functools.cache is released in Python 3.9 (docs):

from functools import cache

@cache
def factorial(n):
    return n * factorial(n-1) if n else 1

In previous versions, one of the early answers is still a valid solution using lru_cache as an ordinary cache without limit and lru feature. (docs)

If maxsize is set to None, the LRU feature is disabled and the cache can grow without bound.

Here is a prettier version of it:

cache = lru_cache(maxsize=None)

@cache
def func(param1):
   pass

I had this error with following statement

Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option in your tsconfig or jsconfig to remove this warning.ts(1219)

It was there because my Component was not registered in AppModule or (app.module.ts) i simply gave the namespace like

import { abcComponent } from '../app/abc/abc.component';

and also registered it in declarations

I can't remember where I found this solution, but I find it to be the most 'elegant' from my non-Python-expert point of view:

class SomeSingleton(dict):
    __instance__ = None
    def __new__(cls, *args,**kwargs):
        if SomeSingleton.__instance__ is None:
            SomeSingleton.__instance__ = dict.__new__(cls)
        return SomeSingleton.__instance__

    def __init__(self):
        pass

    def some_func(self,arg):
        pass

Why do I like this? No decorators, no meta classes, no multiple inheritance...and if you decide you don't want it to be a Singleton anymore, just delete the __new__ method. As I am new to Python (and OOP in general) I expect someone will set me straight about why this is a terrible approach?

I'd agree inheritance is a better fit for the problem posed.

I found this question really handy though on decorating classes, thanks all.

Here's another couple of examples, based on other answers, including how inheritance affects things in Python 2.7, (and @wraps, which maintains the original function's docstring, etc.):

def dec(klass):
    old_foo = klass.foo
    @wraps(klass.foo)
    def decorated_foo(self, *args ,**kwargs):
        print('@decorator pre %s' % msg)
        old_foo(self, *args, **kwargs)
        print('@decorator post %s' % msg)
    klass.foo = decorated_foo
    return klass

@dec  # No parentheses
class Foo...

Often you want to add parameters to your decorator:

from functools import wraps

def dec(msg='default'):
    def decorator(klass):
        old_foo = klass.foo
        @wraps(klass.foo)
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass
    return decorator

@dec('foo decorator')  # You must add parentheses now, even if they're empty
class Foo(object):
    def foo(self, *args, **kwargs):
        print('foo.foo()')

@dec('subfoo decorator')
class SubFoo(Foo):
    def foo(self, *args, **kwargs):
        print('subfoo.foo() pre')
        super(SubFoo, self).foo(*args, **kwargs)
        print('subfoo.foo() post')

@dec('subsubfoo decorator')
class SubSubFoo(SubFoo):
    def foo(self, *args, **kwargs):
        print('subsubfoo.foo() pre')
        super(SubSubFoo, self).foo(*args, **kwargs)
        print('subsubfoo.foo() post')

SubSubFoo().foo()

Outputs:

@decorator pre subsubfoo decorator
subsubfoo.foo() pre
@decorator pre subfoo decorator
subfoo.foo() pre
@decorator pre foo decorator
foo.foo()
@decorator post foo decorator
subfoo.foo() post
@decorator post subfoo decorator
subsubfoo.foo() post
@decorator post subsubfoo decorator

I've used a function decorator, as I find them more concise. Here's a class to decorate a class:

class Dec(object):

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

    def __call__(self, klass):
        old_foo = klass.foo
        msg = self.msg
        def decorated_foo(self, *args, **kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass

A more robust version that checks for those parentheses, and works if the methods don't exist on the decorated class:

from inspect import isclass

def decorate_if(condition, decorator):
    return decorator if condition else lambda x: x

def dec(msg):
    # Only use if your decorator's first parameter is never a class
    assert not isclass(msg)

    def decorator(klass):
        old_foo = getattr(klass, 'foo', None)

        @decorate_if(old_foo, wraps(klass.foo))
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            if callable(old_foo):
                old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)

        klass.foo = decorated_foo
        return klass

    return decorator

The assert checks that the decorator has not been used without parentheses. If it has, then the class being decorated is passed to the msg parameter of the decorator, which raises an AssertionError.

@decorate_if only applies the decorator if condition evaluates to True.

The getattr, callable test, and @decorate_if are used so that the decorator doesn't break if the foo() method doesn't exist on the class being decorated.

In case both the function and the decorator have to take arguments you can follow the below approach.

For example there is a decorator named decorator1 which takes an argument

@decorator1(5)
def func1(arg1, arg2):
    print (arg1, arg2)

func1(1, 2)

Now if the decorator1 argument has to be dynamic, or passed while calling the function,

def func1(arg1, arg2):
    print (arg1, arg2)


a = 1
b = 2
seconds = 10

decorator1(seconds)(func1)(a, b)

In the above code

• seconds is the argument for decorator1
• a, b are the arguments of func1

If the "core problem" is assigning class variables using functions, an alternative is to use a metaclass (it's kind of "annoying" and "magical" and I agree that the static method should be callable inside the class, but unfortunately it isn't). This way, we can refactor the behavior into a standalone function and don't clutter the class.

class KlassMetaClass(type(object)):
    @staticmethod
    def _stat_func():
        return 42

    def __new__(cls, clsname, bases, attrs):
        # Call the __new__ method from the Object metaclass
        super_new = super().__new__(cls, clsname, bases, attrs)
        # Modify class variable "_ANS"
        super_new._ANS = cls._stat_func()
        return super_new

class Klass(object, metaclass=KlassMetaClass):
    """
    Class that will have class variables set pseudo-dynamically by the metaclass
    """
    pass

print(Klass._ANS) # prints 42

Using this alternative "in the real world" may be problematic. I had to use it to override class variables in Django classes, but in other circumstances maybe it's better to go with one of the alternatives from the other answers.

In python 3, below is to make *args and **kwargs into a dict (use OrderedDict for python < 3.6 to maintain dict orders):

from functools import wraps

def display_param(func):
    @wraps(func)
    def wrapper(*args, **kwargs):

        param = inspect.signature(func).parameters
        all_param = {
            k: args[n] if n < len(args) else v.default
            for n, (k, v) in enumerate(param.items()) if k != 'kwargs'
        }
        all_param .update(kwargs)
        print(all_param)

        return func(**all_param)
    return wrapper

Here's what I ended up with. It's a listing of all properties and methods, and I listed all parameters for each method. I didn't succeed on getting all of the values.

foreach(System.Reflection.AssemblyName an in System.Reflection.Assembly.GetExecutingAssembly().GetReferencedAssemblies()){                      
            System.Reflection.Assembly asm = System.Reflection.Assembly.Load(an.ToString());
            foreach(Type type in asm.GetTypes()){   
                //PROPERTIES
                foreach (System.Reflection.PropertyInfo property in type.GetProperties()){
                    if (property.CanRead){
                        Response.Write("<br>" + an.ToString() + "." + type.ToString() + "." + property.Name);       
                    }
                }
                //METHODS
                var methods = type.GetMethods();
                foreach (System.Reflection.MethodInfo method in methods){               
                    Response.Write("<br><b>" + an.ToString() + "."  + type.ToString() + "." + method.Name  + "</b>");   
                    foreach (System.Reflection.ParameterInfo param in method.GetParameters())
                    {
                        Response.Write("<br><i>Param=" + param.Name.ToString());
                        Response.Write("<br>  Type=" + param.ParameterType.ToString());
                        Response.Write("<br>  Position=" + param.Position.ToString());
                        Response.Write("<br>  Optional=" + param.IsOptional.ToString() + "</i>");
                    }
                }
            }
        }

This will turn off interrupts and put the CPU into (permanent until reset/power toggled) sleep:

cli();
sleep_enable();
sleep_cpu();

From Hadoop page,

start-all.sh 

This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.

start-dfs.sh

This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh to separately start the job tracker

start-all.sh/stop-all.sh has to be run on the master node

You would use start-all.sh on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).

In multi-node setup,

You will use start-all.sh on the master node and would start what is necessary on the slaves as well.

Alternatively,

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.

Use start-mapred.sh on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.

hadoop-daemon.sh as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.

Have a look at this start-all.sh it call config followed by dfs and mapred

In this approach only one statement is executed when the UPDATE is successful.

-- For each row in source
BEGIN TRAN    

UPDATE target
SET <target_columns> = <source_values>
WHERE <target_expression>

IF (@@ROWCOUNT = 0)
   INSERT target (<target_columns>)
VALUES (<source_values>)

COMMIT

If you just want to update a few packages and not all, you can list them as such:

php composer.phar update vendor/package:2.* vendor/package2:dev-master

You can also use wildcards to update a bunch of packages at once:

php composer.phar update vendor/*

• --prefer-source: Install packages from source when available.
• --prefer-dist: Install packages from dist when available.
• --ignore-platform-reqs: ignore php, hhvm, lib-* and ext-* requirements and force the installation even if the local machine does not fulfill these. See also the platform config option.
• --dry-run: Simulate the command without actually doing anything.
• --dev: Install packages listed in require-dev (this is the default behavior).
• --no-dev: Skip installing packages listed in require-dev. The autoloader generation skips the autoload-dev rules.
• --no-autoloader: Skips autoloader generation.
• --no-scripts: Skips execution of scripts defined in composer.json.
• --no-plugins: Disables plugins.
• --no-progress: Removes the progress display that can mess with some terminals or scripts which don't handle backspace characters.
• --optimize-autoloader (-o): Convert PSR-0/4 autoloading to classmap to get a faster autoloader. This is recommended especially for production, but can take a bit of time to run so it is currently not done by default.
• --lock: Only updates the lock file hash to suppress warning about the lock file being out of date.
• --with-dependencies: Add also all dependencies of whitelisted packages to the whitelist.
• --prefer-stable: Prefer stable versions of dependencies.
• --prefer-lowest: Prefer lowest versions of dependencies. Useful for testing minimal versions of requirements, generally used with --prefer-stable.

response.GetResponseStream() should be used to return the response stream. And don't forget to close the Stream and Response objects.

I use:

• rails db:drop to delete the databases.
• rails db:create to create the databases based on config/database.yml

The previous commands may be replaced with rails db:reset.

Don't forget to run rails db:migrate to run the migrations.

I used this solution, you have to define the height and width of your screen using MediaQuery:

 Container(
        height: MediaQuery.of(context).size.height,
        width: MediaQuery.of(context).size.width
  )

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

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

The latest and supposedly greatest way to construct the XML is by using LINQ to XML:

using System.Xml.Linq

       var xmlNode =
            new XElement("Login",
                         new XElement("id",
                             new XAttribute("userName", "Tushar"),
                             new XAttribute("password", "Tushar"),
                             new XElement("Name", "Tushar"),
                             new XElement("Age", "24")
                         )
            );
       xmlNode.Save("Tushar.xml");

Supposedly this way of coding should be easier, as the code closely resembles the output (which Jon's example above does not). However, I found that while coding this relatively easy example I was prone to lose my way between the cartload of comma's that you have to navigate among. Visual studio's auto spacing of code does not help either.

I found out that it also happens if you uninstalled some packages from your react-native project and there is still packages in your build gradle dependencies in the bottom of page like:

{
 project(':react-native-sound-player')
}

Here's a solution that's part of the standard library:

from distutils.dir_util import copy_tree
copy_tree("/a/b/c", "/x/y/z")

See this similar question.

Copy directory contents into a directory with python

• Reference - https://docs.python.org/3/distutils/apiref.html#distutils.dir_util.copy_tree

You can use the -notmatch operator to get the lines that don't have the characters you are interested in.

     Get-Content $FileName | foreach-object { 
     if ($_ -notmatch $arrayofStringsNotInterestedIn) { $) }

While a = 'foo' if True else 'bar' is the more modern way of doing the ternary if statement (python 2.5+), a 1-to-1 equivalent of your version might be:

a = (b == True and "123" or "456" )

... which in python should be shortened to:

a = b is True and "123" or "456"

... or if you simply want to test the truthfulness of b's value in general...

a = b and "123" or "456"

? : can literally be swapped out for and or

When getting the substring of a CLOB column and using a query tool that has size/buffer restrictions sometimes you would need to set the BUFFER to a larger size. For example while using SQL Plus use the SET BUFFER 10000 to set it to 10000 as the default is 4000.

Running the DBMS_LOB.substr command you can also specify the amount of characters you want to return and the offset from which. So using DBMS_LOB.substr(column, 3000) might restrict it to a small enough amount for the buffer.

See oracle documentation for more info on the substr command

    DBMS_LOB.SUBSTR (
       lob_loc     IN    CLOB   CHARACTER SET ANY_CS,
       amount      IN    INTEGER := 32767,
       offset      IN    INTEGER := 1)
      RETURN VARCHAR2 CHARACTER SET lob_loc%CHARSET;

Andy E is correct that there is no HTML-based way to do this*; but if you are willing to use Flash, you can do it. The following works reliably on systems that have Flash installed. If your app needs to work on iPhone, then of course you'll need a fallback HTML-based solution.

* (Update 4/22/2013: HTML does now support this, in HTML5. See the other answers.)

Flash uploading also has other advantages -- Flash gives you the ability to show a progress bar as the upload of a large file progresses. (I'm pretty sure that's how Gmail does it, by using Flash behind the scenes, although I may be wrong about that.)

Here is a sample Flex 4 app that allows the user to pick a file, and then displays it:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark"

               creationComplete="init()">
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:Button x="10" y="10" label="Choose file..." click="showFilePicker()" />
    <mx:Image id="myImage" x="9" y="44"/>
    <fx:Script>
        <![CDATA[
            private var fr:FileReference = new FileReference();

            // Called when the app starts.
            private function init():void
            {
                // Set up event handlers.
                fr.addEventListener(Event.SELECT, onSelect);
                fr.addEventListener(Event.COMPLETE, onComplete);
            }

            // Called when the user clicks "Choose file..."
            private function showFilePicker():void
            {
                fr.browse();
            }

            private function onSelect(e:Event):void
            {
                fr.load(); // start reading the file
            }

            // that the file has finished loading.

                myImage.data = fr.data; // load the file's data into the Image

        ]]>

Thanks to @RubberDuck's comment and @Emil's answer I was able to figure out what the problem was. The IDs of most elements in my XML file were exactly the same. So, I renamed each and every one of them. Also, my XML file contained capital letters. The filename should be in [a-z0-9_] so I renamed my files too and the problem was solved.

If you need to work on different databases:

DECLARE @Catalog VARCHAR(255)
SET @Catalog = 'MyDatabase'

DECLARE @Schema VARCHAR(255)
SET @Schema = 'dbo'

DECLARE @Table VARCHAR(255)
SET @Table = 'MyTable'

IF (EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES   
    WHERE TABLE_CATALOG = @Catalog 
      AND TABLE_SCHEMA = @Schema 
      AND TABLE_NAME = @Table))
BEGIN
   --do stuff
END

You need to uninstall IIS (Internet Information Services) but the key thing here is to make sure you uninstall the Windows Process Activation Service or otherwise your ApplicationHost.config will be still around. When you uninstall WAS then your configuration will be cleaned up and you will truly start with a fresh new IIS (and all data/configuration will be lost).

You can try this:

var theValue = document.getElementById("demo").getAttribute("value");

To call a specific exception such as FileNotFoundException use this format

if (-not (Test-Path $file)) 
{
    throw [System.IO.FileNotFoundException] "$file not found."
}

To throw a general exception use the throw command followed by a string.

throw "Error trying to do a task"

When used inside a catch, you can provide additional information about what triggered the error

I can see at least three options:

1.

df[:10]

2. Using head

df.head(10)

For negative values of n, this function returns all rows except the last n rows, equivalent to df[:-n] [Source].

3. Using iloc

df.iloc[:10]

You technically have two options when speaking of ISO dates.

In general, if you're filtering specifically on Date values alone OR looking to persist date in a neutral fashion. Microsoft recommends using the language neutral format of ymd or y-m-d. Which are both valid ISO formats.

Note that the form '2007-02-12' is considered language-neutral only for the data types DATE, DATETIME2, and DATETIMEOFFSET.

Because of this, your safest bet is to persist/filter based on the always netural ymd format.

The code:

select convert(char(10), getdate(), 126) -- ISO YYYY-MM-DD
select convert(char(8), getdate(), 112) -- ISO YYYYMMDD (safest)

In a BST, all values descending on the left side of a node are less than (or equal to, see later) the node itself. Similarly, all values descending on the right side of a node are greater than (or equal to) that node value^(a).

Some BSTs may choose to allow duplicate values, hence the "or equal to" qualifiers above. The following example may clarify:

     14
    /  \
  13    22
 /     /  \
1    16    29
          /  \
        28    29

This shows a BST that allows duplicates^(b) - you can see that to find a value, you start at the root node and go down the left or right subtree depending on whether your search value is less than or greater than the node value.

This can be done recursively with something like:

def hasVal (node, srchval):
    if node == NULL:
         return false
    if node.val == srchval:
        return true
    if node.val > srchval:
        return hasVal (node.left, srchval)
    return hasVal (node.right, srchval)

and calling it with:

foundIt = hasVal (rootNode, valToLookFor)

Duplicates add a little complexity since you may need to keep searching once you've found your value, for other nodes of the same value. Obviously that doesn't matter for hasVal since it doesn't matter how many there are, just whether at least one exists. It will however matter for things like countVal, since it needs to know how many there are.

^(a) You could actually sort them in the opposite direction should you so wish provided you adjust how you search for a specific key. A BST need only maintain some sorted order, whether that's ascending or descending (or even some weird multi-layer-sort method like all odd numbers ascending, then all even numbers descending) is not relevant.

^(b) Interestingly, if your sorting key uses the entire value stored at a node (so that nodes containing the same key have no other extra information to distinguish them), there can be performance gains from adding a count to each node, rather than allowing duplicate nodes.

The main benefit is that adding or removing a duplicate will simply modify the count rather than inserting or deleting a new node (an action that may require re-balancing the tree).

So, to add an item, you first check if it already exists. If so, just increment the count and exit. If not, you need to insert a new node with a count of one then rebalance.

To remove an item, you find it then decrement the count - only if the resultant count is zero do you then remove the actual node from the tree and rebalance.

Searches are also quicker given there are fewer nodes but that may not be a large impact.

For example, the following two trees (non-counting on the left, and counting on the right) would be equivalent (in the counting tree, i.c means c copies of item i):

     __14__                    ___22.2___
    /      \                  /          \
  14        22             7.1            29.1
 /  \      /  \           /   \          /    \
1    14  22    29      1.1     14.3  28.1      30.1
 \            /  \
  7         28    30

Removing the leaf-node 22 from the left tree would involve rebalancing (since it now has a height differential of two) the resulting 22-29-28-30 subtree such as below (this is one option, there are others that also satisfy the "height differential must be zero or one" rule):

\                      \
 22                     29
   \                   /  \
    29      -->      28    30
   /  \             /
 28    30         22

Doing the same operation on the right tree is a simple modification of the root node from 22.2 to 22.1 (with no rebalancing required).

var stringDate = "Sunday, February 28, 2010";

var months = ["January", "February", "March"]; // You add the rest  :-)

var m = /(\w+) (\d+), (\d+)/.exec(stringDate);

var date = new Date(+m[3], months.indexOf(m[1]), +m[2]);

The indexOf method on arrays is only supported on newer browsers (i.e. not IE). You'll need to do the searching yourself or use one of the many libraries that provide the same functionality.

Also the code is lacking any error checking which should be added. (String not matching the regular expression, non existent months, etc.)

I've seen only one simple way of reading an arbitrarily long string, but I've never used it. I think it goes like this:

char *m = NULL;
printf("please input a string\n");
scanf("%ms",&m);
if (m == NULL)
    fprintf(stderr, "That string was too long!\n");
else
{
    printf("this is the string %s\n",m);
    /* ... any other use of m */
    free(m);
}

The m between % and s tells scanf() to measure the string and allocate memory for it and copy the string into that, and to store the address of that allocated memory in the corresponding argument. Once you're done with it you have to free() it.

This isn't supported on every implementation of scanf(), though.

As others have pointed out, the easiest solution is to set a limit on the length of the input. If you still want to use scanf() then you can do so this way:

char m[100];
scanf("%99s",&m);

Note that the size of m[] must be at least one byte larger than the number between % and s.

If the string entered is longer than 99, then the remaining characters will wait to be read by another call or by the rest of the format string passed to scanf().

Generally scanf() is not recommended for handling user input. It's best applied to basic structured text files that were created by another application. Even then, you must be aware that the input might not be formatted as you expect, as somebody might have interfered with it to try to break your program.

MS already made a method for this, so you dont have to use the null coalescing operator. No difference in functionality, but it is easier for non-experts to get what is happening at a glance.

DateTime updatedTime = _objHotelPackageOrder.UpdatedDate.GetValueOrDefault(DateTime.Now);

call below method on div or body tag onclick="show(event);" function show(event) {

        var x = event.clientX;
        var y = event.clientY;

        var ele = document.getElementById("tt");
        var width = ele.offsetWidth;
        var height = ele.offsetHeight;
        var half=(width/2);
       if(x>half)
        {
          //  alert('right click');
            gallery.next();
        }
        else
       {
           //   alert('left click');
            gallery.prev();
        }


    }

Your should create ptr as follows:

char *ptr;

You have created ptr as an array of pointers to chars. The above creates a single pointer to a char.

Edit: complete code should be:

char *ptr;
char arr[5] = {'a','b','c','d','e'};
ptr = arr;
printf("\nvalue:%c", *(ptr+0));

After studying the Internet for a day I found my own solution for selecting an item after create a normal treeview in a normal WPF/C# environment

private void BuildSortTree(int sel)
        {
            MergeSort.Items.Clear();
            TreeViewItem itTemp = new TreeViewItem();
            itTemp.Header = SortList[0];
            MergeSort.Items.Add(itTemp);
            TreeViewItem prev;
            itTemp.IsExpanded = true;
            if (0 == sel) itTemp.IsSelected= true;
            prev = itTemp;
            for(int i = 1; i<SortList.Count; i++)
            {

                TreeViewItem itTempNEW = new TreeViewItem();
                itTempNEW.Header = SortList[i];
                prev.Items.Add(itTempNEW);
                itTempNEW.IsExpanded = true;
                if (i == sel) itTempNEW.IsSelected = true;
                prev = itTempNEW ;
            }
        }

You can use a resource key like this:

<UserControl.Resources>
    <SolidColorBrush x:Key="{x:Static local:Foo.MyKey}">Blue</SolidColorBrush>
</UserControl.Resources>
<Grid Background="{StaticResource {x:Static local:Foo.MyKey}}" />

public partial class Foo : UserControl
{
    public Foo()
    {
        InitializeComponent();
        var brush = (SolidColorBrush)FindResource(MyKey);
    }

    public static ResourceKey MyKey { get; } = CreateResourceKey();

    private static ComponentResourceKey CreateResourceKey([CallerMemberName] string caller = null)
    {
        return new ComponentResourceKey(typeof(Foo), caller); ;
    }
}

The problem with the answer that was chosen here is that when navigating back and forth, the converter will get triggered every time the page is shown.

This causes new file handles to be created continuously and will block any attempt to delete the file because it is still in use. This can be verified by using Process Explorer.

If the image file might be deleted at some point, a converter such as this might be used: using XAML to bind to a System.Drawing.Image into a System.Windows.Image control

The disadvantage with this memory stream method is that the image(s) get loaded and decoded every time and no caching can take place: "To prevent images from being decoded more than once, assign the Image.Source property from an Uri rather than using memory streams" Source: "Performance tips for Windows Store apps using XAML"

To solve the performance issue, the repository pattern can be used to provide a caching layer. The caching could take place in memory, which may cause memory issues, or as thumbnail files that reside in a temp folder that can be cleared when the app exits.

Yes, it hides a variable in a module from other modules. In C++, I use it when I don't want/need to change a .h file that will trigger an unnecessary rebuild of other files. Also, I put the static first:

static const int foo = 42;

Also, depending on its use, the compiler won't even allocate storage for it and simply "inline" the value where it's used. Without the static, the compiler can't assume it's not being used elsewhere and can't inline.

The safest way to load htmlContent in a Web view is to:

1. use base64 encoding (official recommendation)
2. specify UFT-8 for html content type, i.e., "text/html; charset=utf-8" instead of "text/html" (personal advice)

"Base64 encoding" is an official recommendation that has been written again (already present in Javadoc) in the latest 01/2019 bug in Chrominium (present in WebView M72 (72.0.3626.76)):

https://bugs.chromium.org/p/chromium/issues/detail?id=929083

Official statement from Chromium team:

"Recommended fix:
Our team recommends you encode data with Base64. We've provided examples for how to do so:

• API docs: https://developer.android.com/reference/android/webkit/WebView.html#loadData(java.lang.String,%20java.lang.String,%20java.lang.String)
• Video talk: https://youtu.be/HGZYtDZhOEQ?t=598 (jump to time stamp 9:58)

This fix is backwards compatible (it works on earlier WebView versions), and should also be future-proof (you won't hit future compatibility problems with respect to content encoding)."

Code sample:

webView.loadData(
    Base64.encodeToString(
        htmlContent.getBytes(StandardCharsets.UTF_8),
        Base64.DEFAULT), // encode in Base64 encoded 
    "text/html; charset=utf-8", // utf-8 html content (personal recommendation)
    "base64"); // always use Base64 encoded data: NEVER PUT "utf-8" here (using base64 or not): This is wrong! 

From what I know, add an __init__.py file directly in the folder of the functions you want to import will do the job.

Use a negative match. (Also note that whitespace is significant, by default, inside a regex so don't space things out. Alternatively, use re.VERBOSE.)

for item in output:
    matchObj = re.search("^(OK|\\.)", item)
    if not matchObj:
        print "got item " + item

You need to install a so-called Instance of MSSQL server on your computer. That is, installing all the needed files and services and database files. By default, there should be no MSSQL Server installed on your machine, assuming that you use a desktop Windows (7,8,10...).

You can start off with Microsoft SQL Server Express, which is a 10GB-limited, free version of MSSQL. It also lacks some other features (Server Agents, AFAIR), but it's good for some experiments.

Download it from the Microsoft Website and go through the installer process by choosing New SQL Server stand-alone installation .. after running the installer.

Click through the steps. For your scenario (it sounds like you mainly want to test some stuff), the default options should suffice.

Just give attention to the step Instance Configuration. There you will set the name of your MSSQL Server Instance. Call it something unique/descriptive like MY_TEST_INSTANCE or the like. Also, choose wisely the Instance root directory. In it, the database files will be placed, so it should be on a drive that has enough space.

Click further through the wizard, and when it's finished, your MSSQL instance will be up and running. It will also run at every boot if you have chosen the default settings for the services.

As soon as it's running in the background, you can connect to it with Management Studio by connecting to .\MY_TEST_INSTANCE, given that that's the name you chose for the instance.

What character encoding are you using? Some character sets (like UTF-16, et cetera) use more than one byte per character.

I believe you can loop through the properties of the object using for/in, so you could do something like this:

function getKeys(h) {
  Array keys = new Array();
  for (var key in h)
    keys.push(key);
  return keys;
}

select * into newtable from oldtable

This is a select statement, so each branch of the case must return something. If you want to perform actions, just use an if.

You go into your router configuration and forward port 80 to the LAN IP of the computer running the web server.

Then anyone outside your network (but not you inside the network) can access your site using your WAN IP address (whatismyipcom).

var_export provides the desired functionality.

This will always print a value rather than printing nothing for null or false. var_export prints a PHP representation of the argument it's passed, the output could be copy/pasted back into PHP.

var_export(true);    // true
var_export(false);   // false
var_export(1);       // 1
var_export(0);       // 0
var_export(null);    // NULL
var_export('true');  // 'true'   <-- note the quotes
var_export('false'); // 'false'

If you want to print strings "true" or "false", you can cast to a boolean as below, but beware of the peculiarities:

var_export((bool) true);   // true
var_export((bool) false);  // false
var_export((bool) 1);      // true
var_export((bool) 0);      // false
var_export((bool) '');     // false
var_export((bool) 'true'); // true
var_export((bool) null);   // false

// !! CAREFUL WITH CASTING !!
var_export((bool) 'false'); // true
var_export((bool) '0');     // false

# sudo apt-get install g++-multilib

Should fix this error on 64-bit machines (Debian/Ubuntu).

I found that I moved my DEBUG setting in my local settings to be overwritten by a default False value. Essentially look to make sure the DEBUG setting is actually false if you are developing with DEBUG and runserver.

"If I want two columns for anything over 768px, should I apply both classes?"

This should be as simple as:

<div class="row">
      <div class="col-sm-6"></div>
      <div class="col-sm-6"></div>    
</div>

No need to add the col-lg-6 too.

The signature:

bool operator<<(const obj&, const obj&);

Seems rather suspect, this does not fit the stream convention nor the bitwise convention so it looks like a case of operator overloading abuse, operator < should return bool but operator << should probably return something else.

If you meant so say:

ostream& operator<<(ostream&, const obj&); 

Then since you can't add functions to ostream by necessity the function must be a free function, whether it a friend or not depends on what it has to access (if it doesn't need to access private or protected members there's no need to make it friend).

Most likely, you need to have the Javascript served over SSL.

If anyone cares, for NTEXT, use the following format:

SELECT CAST(REPLACE(CAST([ColumnValue] AS NVARCHAR(MAX)),'find','replace') AS NTEXT) 
    FROM [DataTable]

You can use custom validation:

    [CustomValidation(typeof(ValidationMethods), "ValidateGreaterOrEqualToZero")]
    public int IntValue { get; set; }

    [CustomValidation(typeof(ValidationMethods), "ValidateGreaterOrEqualToZero")]
    public decimal DecValue { get; set; }

Validation methods type:

public class ValidationMethods
{
    public static ValidationResult ValidateGreaterOrEqualToZero(decimal value, ValidationContext context)
    {
        bool isValid = true;

        if (value < decimal.Zero)
        {
            isValid = false;
        }

        if (isValid)
        {
            return ValidationResult.Success;
        }
        else
        {
            return new ValidationResult(
                string.Format("The field {0} must be greater than or equal to 0.", context.MemberName),
                new List<string>() { context.MemberName });
        }

}

Complementing the previous answers, one big difference between both is that Visual Studio Code comes in a so called "portable" version that does not require full administrative permissions to run on Windows and can be placed in a removable drive for convenience.

Make sure that your connection charset to MySQL is UTF-8. It often defaults to ISO-8859-1 which means that the MySQL driver will convert the text to ISO-8859-1.

You can set the connection charset with mysql_set_charset, mysqli_set_charset or with the query SET NAMES 'utf-8'

I am looking for opinions of how to handle large binary files on which my source code (web application) is dependent. What are your experiences/thoughts regarding this?

I personally have run into synchronisation failures with Git with some of my cloud hosts once my web applications binary data notched above the 3 GB mark. I considered BFT Repo Cleaner at the time, but it felt like a hack. Since then I've begun to just keep files outside of Git purview, instead leveraging purpose-built tools such as Amazon S3 for managing files, versioning and back-up.

Does anybody have experience with multiple Git repositories and managing them in one project?

Yes. Hugo themes are primarily managed this way. It's a little kudgy, but it gets the job done.

My suggestion is to choose the right tool for the job. If it's for a company and you're managing your codeline on GitHub pay the money and use Git-LFS. Otherwise you could explore more creative options such as decentralized, encrypted file storage using blockchain.

Additional options to consider include Minio and s3cmd.

Max is on he right track with the suggestion to use Windows Scripting for a way to do it without installing any additional executables on the machine. His code will work if you have the IIS SMTP service setup to forward outbound email using the "smart host" setting, or the machine also happens to be running Microsoft Exchange. Otherwise if this is not configured, you will find your emails just piling up in the message queue folder (\inetpub\mailroot\queue). So, unless you can configure this service, you also want to be able to specify the email server you want to use to send the message with. To do that, you can do something like this in your windows script file:

Set objMail = CreateObject("CDO.Message")
Set objConf = CreateObject("CDO.Configuration")
Set objFlds = objConf.Fields
objFlds.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 'cdoSendUsingPort
objFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.your-site-url.com" 'your smtp server domain or IP address goes here
objFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25 'default port for email
'uncomment next three lines if you need to use SMTP Authorization
'objFlds.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "your-username"
'objFlds.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "your-password"
'objFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1 'cdoBasic
objFlds.Update
objMail.Configuration = objConf
objMail.FromName = "Your Name"
objMail.From = "[email protected]"
objMail.To = "[email protected]"
objMail.Subject = "Email Subject Text"
objMail.TextBody = "The message of the email..."
objMail.Send
Set objFlds = Nothing
Set objConf = Nothing
Set objMail = Nothing

max-age
    When an intermediate cache is forced, by means of a max-age=0 directive, to revalidate 
its own cache entry, and the client has supplied its own validator in the request, the 
supplied validator might differ from the validator currently stored with the cache entry. 
In this case, the cache MAY use either validator in making its own request without 
affecting semantic transparency. 

    However, the choice of validator might affect performance. The best approach is for the 
intermediate cache to use its own validator when making its request. If the server replies 
with 304 (Not Modified), then the cache can return its now validated copy to the client 
with a 200 (OK) response. If the server replies with a new entity and cache validator, 
however, the intermediate cache can compare the returned validator with the one provided in 
the client's request, using the strong comparison function. If the client's validator is 
equal to the origin server's, then the intermediate cache simply returns 304 (Not 
Modified). Otherwise, it returns the new entity with a 200 (OK) response. 

    If a request includes the no-cache directive, it SHOULD NOT include min-fresh, 
max-stale, or max-age.

Don't accept this as answer - I will have to read it to understand the true usage of it :)

It is possible to have private methods in classes using WeakMap.

According to MDN web docs:

The WeakMap object is a collection of key/value pairs in which the keys are objects only and the values can be arbitrary values.

The object references in the keys are held weakly, meaning that they are a target of garbage collection (GC) if there is no other reference to the object anymore.

And this is an example of creating Queue data structure with a private member _items which holds an array.

const _items = new WeakMap();

class Queue {    
    constructor() {
        _items.set(this, []);
    }

    enqueue( item) {
        _items.get(this).push(item);
    }    

    get count() {
        return _items.get(this).length;        
    }

    peek() {
        const anArray = _items.get(this);
        if( anArray.length == 0)
            throw new Error('There are no items in array!');

        if( anArray.length > 0)
            return anArray[0];
    }

    dequeue() {        
        const anArray = _items.get(this);
        if( anArray.length == 0)
            throw new Error('There are no items in array!');

        if( anArray.length > 0)
            return anArray.splice(0, 1)[0];
    }    
}

An example of using:

const c = new Queue();
c.enqueue("one");
c.enqueue("two");
c.enqueue("three");
c.enqueue("four");
c.enqueue("five");
console.log(c);

Private member _items is hided and cannot be seen in properties or methods of an Queue object:

However, private member _items in the Queue object can be reached using this way:

const anArray = _items.get(this);

In your layout XML file :

• set android:inputType="textCapSentences"

• On your EditText to have first alphabet of the first word of each sentence as capital

• Or android:inputType="textCapWords" on your EditText to have first alphabet of each word as capital

opposite of 'none' is 'flex' while working with react native.

Resetting the branch to the dangling commit object of its old tip is of course the best solution, because it restores the previous state without expending any effort. But if you happen to have lost those commits (f.ex. because you garbage-collected your repository in the meantime, or this is a fresh clone), you can always rebase the branch again. The key to this is the --onto switch.

Let’s say you had a topic branch imaginatively called topic, that you branched off master when the tip of master was the 0deadbeef commit. At some point while on the topic branch, you did git rebase master. Now you want to undo this. Here’s how:

git rebase --onto 0deadbeef master topic

This will take all commits on topic that aren’t on master and replay them on top of 0deadbeef.

With --onto, you can rearrange your history into pretty much any shape whatsoever.

Have fun. :-)

I used Anaconda environment and had the same issue. I tried all the aforementioned approaches and, alas, it didn't help me. Accumulated the suggestions, here the way which helped me:

1. Delete all NumPy folders in the virtual environment or in the system if you don't use a virtual environment, for example in my case:

   ~/home/anaconda3/envs//lib/python/site-packages/numpy

   ~/home/anaconda3/envs//lib/python/site-packages/numpy.libs

   ~/home/anaconda3/envs//lib/python/site-packages/numpy-.dist-info

2. Install new Numpy with:

   pip install numpy -U

Hope, it could help in the same case

Or you can do it like as well:

<asp:DropDownList ID="ddl" runat="server"  AutoPostBack="true" onchange="javascript:CalcTotalAmt();" OnSelectedIndexChanged="ddl_SelectedIndexChanged"></asp:DropDownList>

Here is a quick summary of the segues and an example for each type.

Show - Pushes the destination view controller onto the navigation stack, sliding overtop from right to left, providing a back button to return to the source - or if not embedded in a navigation controller it will be presented modally
Example: Navigating inboxes/folders in Mail

Show Detail - For use in a split view controller, replaces the detail/secondary view controller when in an expanded 2 column interface, otherwise if collapsed to 1 column it will push in a navigation controller
Example: In Messages, tapping a conversation will show the conversation details - replacing the view controller on the right when in a two column layout, or push the conversation when in a single column layout

Present Modally - Presents a view controller in various animated fashions as defined by the Presentation option, covering the previous view controller - most commonly used to present a view controller that animates up from the bottom and covers the entire screen on iPhone, or on iPad it's common to present it as a centered box that darkens the presenting view controller
Example: Selecting Touch ID & Passcode in Settings

Popover Presentation - When run on iPad, the destination appears in a popover, and tapping anywhere outside of this popover will dismiss it, or on iPhone popovers are supported as well but by default it will present the destination modally over the full screen
Example: Tapping the + button in Calendar

Custom - You may implement your own custom segue and have control over its behavior

The deprecated segues are essentially the non-adaptive equivalents of those described above. These segue types were deprecated in iOS 8: Push, Modal, Popover, Replace.

For more info, you may read over the Using Segues documentation which also explains the types of segues and how to use them in a Storyboard. Also check out Session 216 Building Adaptive Apps with UIKit from WWDC 2014. They talked about how you can build adaptive apps using these new Adaptive Segues, and they built a demo project that utilizes these segues.

There is one more way to achieve it:-

Private Sub UserForm_Initialize()
Dim list As Object
Set list = UserForm1.Controls.Add("Forms.ListBox.1", "hello", True)
With list
    .Top = 30
    .Left = 30
    .Width = 200
    .Height = 340
    .ColumnHeads = True
    .ColumnCount = 2
    .ColumnWidths = "100;100"
    .MultiSelect = fmMultiSelectExtended
    .RowSource = "Sheet1!C4:D25"
End With End Sub

Here, I am using the range C4:D25 as source of data for the columns. It will result in both the columns populated with values.

The properties are self explanatory. You can explore other options by drawing ListBox in UserForm and using "Properties Window (F4)" to play with the option values.

In more recent browsers code like below may be enough.

<object data="https://www.w3.org/TR/PNG/iso_8859-1.txt" width="300" height="200">_x000D_
Not supported_x000D_
</object>

function getValue(obj)
{  
   // it will return the selected text
   // obj variable will contain the object of check box
   var text = obj.options[obj.selectedIndex].innerHTML ; 

}

HTML Snippet

 <asp:DropDownList ID="ddl" runat="server" CssClass="ComboXXX" 
  onchange="getValue(this)">
</asp:DropDownList>

This regex validates dates between 01-01-2000 and 12-31-2099 with matching separators.

^(0[1-9]|1[012])([- /.])(0[1-9]|[12][0-9]|3[01])\2(19|20)\d\d$

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

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

Starting from scratch function has Some Memory Address From Where They start executing. In Assembly Language They Are called as (call "function's memory address").Now come back to C If function has a memory address then they can be manipulated by Pointers in C.So By the rules of C

1.First you need to declare a pointer to function 2.Pass the Address of the Desired function

****Note->the functions should be of same type****

This Simple Programme will Illustrate Every Thing.

#include<stdio.h>
void (*print)() ;//Declare a  Function Pointers
void sayhello();//Declare The Function Whose Address is to be passed
                //The Functions should Be of Same Type
int main()
{
 print=sayhello;//Addressof sayhello is assigned to print
 print();//print Does A call To The Function 
 return 0;
}

void sayhello()
{
 printf("\n Hello World");
}

After That lets See How machine Understands Them.Glimpse of machine instruction of the above programme in 32 bit architecture.

The red mark area is showing how the address is being exchanged and storing in eax. Then their is a call instruction on eax. eax contains the desired address of the function.

The problem is that (as of 2016), for the password field, Firefox and Internet Explorer use the character "Black Circle" (?), which uses the Unicode code point 25CF, but Chrome uses the character "Bullet" (•), which uses the Unicode code point 2022.

As you can see, even in the StackOverflow font the two characters have different sizes.

The font you're using, "Lucida Sans Unicode", has an even greater disparity between the sizes of these two characters, leading to you noticing the difference.

The simple solution is to use a font in which both characters have similar sizes.

The fix could thus be to use a default font of the browser, which should render the characters in the password field just fine:

input[type="password"] {
    font-family: caption;
}

You need to use MM as mm stands for minutes.

There are two ways of producing month pattern.

SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy"); //outputs month in numeric way, 2013-02-01

SimpleDateFormat sdf2 = new SimpleDateFormat("dd-MMM-yyyy"); // Outputs months as follows, 2013-Feb-01

Full coding snippet:

        String startDate="01-Feb-2013"; // Input String
        SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy"); // New Pattern
        java.util.Date date = sdf1.parse(startDate); // Returns a Date format object with the pattern
        java.sql.Date sqlStartDate = new java.sql.Date(date.getTime());
        System.out.println(sqlStartDate); // Outputs : 2013-02-01

I found this answer here:

if(($twitter_XML_raw=file_get_contents($timeline))==false){
    // Retrieve HTTP status code
    list($version,$status_code,$msg) = explode(' ',$http_response_header[0], 3);

    // Check the HTTP Status code
    switch($status_code) {
        case 200:
                $error_status="200: Success";
                break;
        case 401:
                $error_status="401: Login failure.  Try logging out and back in.  Password are ONLY used when posting.";
                break;
        case 400:
                $error_status="400: Invalid request.  You may have exceeded your rate limit.";
                break;
        case 404:
                $error_status="404: Not found.  This shouldn't happen.  Please let me know what happened using the feedback link above.";
                break;
        case 500:
                $error_status="500: Twitter servers replied with an error. Hopefully they'll be OK soon!";
                break;
        case 502:
                $error_status="502: Twitter servers may be down or being upgraded. Hopefully they'll be OK soon!";
                break;
        case 503:
                $error_status="503: Twitter service unavailable. Hopefully they'll be OK soon!";
                break;
        default:
                $error_status="Undocumented error: " . $status_code;
                break;
    }

Essentially, you use the "file get contents" method to retrieve the URL, which automatically populates the http response header variable with the status code.

You can use something like this:

<?php
array_walk_recursive(
$array, function (&$value)
{
 $value = htmlspecialchars(html_entity_decode($value, ENT_QUOTES, 'UTF-8'), ENT_QUOTES, 'UTF-8');
}
);
?>

Since setOnClickListener is defined on View not Button, if you don't need the variable for something else, you could make it a little terser like this:

findViewById(R.id.buttonXName).setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
    //DO SOMETHING! {RUN SOME FUNCTION ... DO CHECKS... ETC}
    } 
});

The main reason you use the default queue over the main queue is to run tasks in the background.

For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.

dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
    //Background Thread
    dispatch_async(dispatch_get_main_queue(), ^(void){
        //Run UI Updates
    });
});

Well the first can be achieved with the document.ready function in jquery

$(document).ready(function(){...});

The changing image can be achieved with any number of plugins

• http://malsup.com/jquery/cycle/
• http://www.matto1990.com/jquery/slideshow/

If you wish you can check if images are loaded with the complete property. I know that at least the malsup jquery cycle slideshow makes use of this function internally.

Based on your question and also noted in comment.

Can someone guide me on how to update User info in the database?

Yes, the code is correct for updating any ApplicationUser to the database.

IdentityResult result = await UserManager.UpdateAsync(user);

• Check for constrains of all field's required values
• Check for UserManager is created using ApplicationUser.

UserManager<ApplicationUser> UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));

Here is a small example how to do it with powermock

public class Hello {
    private Hello obj;
    private Integer method1(Long id) {
        return id + 10;
    }
} 

To test method1 use code:

Hello testObj = new Hello();
Integer result = Whitebox.invokeMethod(testObj, "method1", new Long(10L));

To set private object obj use this:

Hello testObj = new Hello();
Hello newObject = new Hello();
Whitebox.setInternalState(testObj, "obj", newObject);

A referral is sent by an AD server when it doesn't have the information requested itself, but know that another server have the info. It usually appears in trust environment where a DC can refer to a DC in trusted domain.

In your case you are only specifying a domain, relying on automatic lookup of what domain controller to use. I think that you should try to find out what domain controller is used for the query and look if that one really holds the requested information.

If you provide more information on your AD setup, including any trusts/subdomains, global catalogues and the DNS resource records for the domain controllers it will be easier to help you.

There is more than one way to define "memory leak". In particular, there are two primary definitions of "memory leak" that are in common usage among programmers.

The first commonly used definition of "memory leak" is, "Memory was allocated and was not subsequently freed before the program terminated." However, many programmers (rightly) argue that certain types of memory leaks that fit this definition don't actually pose any sort of problem, and therefore should not be considered true "memory leaks".

An arguably stricter (and more useful) definition of "memory leak" is, "Memory was allocated and cannot be subsequently freed because the program no longer has any pointers to the allocated memory block." In other words, you cannot free memory that you no longer have any pointers to. Such memory is therefore a "memory leak". Valgrind uses this stricter definition of the term "memory leak". This is the type of leak which can potentially cause significant heap depletion, especially for long lived processes.

The "still reachable" category within Valgrind's leak report refers to allocations that fit only the first definition of "memory leak". These blocks were not freed, but they could have been freed (if the programmer had wanted to) because the program still was keeping track of pointers to those memory blocks.

In general, there is no need to worry about "still reachable" blocks. They don't pose the sort of problem that true memory leaks can cause. For instance, there is normally no potential for heap exhaustion from "still reachable" blocks. This is because these blocks are usually one-time allocations, references to which are kept throughout the duration of the process's lifetime. While you could go through and ensure that your program frees all allocated memory, there is usually no practical benefit from doing so since the operating system will reclaim all of the process's memory after the process terminates, anyway. Contrast this with true memory leaks which, if left unfixed, could cause a process to run out of memory if left running long enough, or will simply cause a process to consume far more memory than is necessary.

Probably the only time it is useful to ensure that all allocations have matching "frees" is if your leak detection tools cannot tell which blocks are "still reachable" (but Valgrind can do this) or if your operating system doesn't reclaim all of a terminating process's memory (all platforms which Valgrind has been ported to do this).

I'm working on Crud for my app. This is how I did it Got Reactstrap as my dependency.

import React, { useState, setState } from 'react';
import 'bootstrap/dist/css/bootstrap.min.css';
import firebase from 'firebase';
// import { LifeCrud } from '../CRUD/Crud';
import { Row, Card, Col, Button } from 'reactstrap';
import InsuranceActionInput from '../CRUD/InsuranceActionInput';

const LifeActionCreate = () => {
  let [newLifeActionLabel, setNewLifeActionLabel] = React.useState();

  const onCreate = e => {
    const db = firebase.firestore();

    db.collection('actions').add({
      label: newLifeActionLabel
    });
    alert('New Life Insurance Added');
    setNewLifeActionLabel('');
  };

  return (
    <Card style={{ padding: '15px' }}>
      <form onSubmit={onCreate}>
        <label>Name</label>
        <input
          value={newLifeActionLabel}
          onChange={e => {
            setNewLifeActionLabel(e.target.value);
          }}
          placeholder={'Name'}
        />

        <Button onClick={onCreate}>Create</Button>
      </form>
    </Card>
  );
};

Some React Hooks in there

var result = from sc in enumerableOfSomeClass
             join soc in enumerableOfSomeOtherClass
             on sc.Property1 equals soc.Property2
             select new { SomeClass = sc, SomeOtherClass = soc };

Would be equivalent to:

var result = enumerableOfSomeClass
    .Join(enumerableOfSomeOtherClass,
          sc => sc.Property1,
          soc => soc.Property2,
          (sc, soc) => new
                       {
                           SomeClass = sc,
                           SomeOtherClass = soc
                       });

As you can see, when it comes to joins, query syntax is usually much more readable than lambda syntax.

Your file seems quite small (297 lines) so you can read and write them quite quickly. You refer to Excel CSV, which does not exists, and you show space delimited data in your example. Furthermore, Access is limited to 255 columns, and a CSV is not, so there is no guarantee this will work

Sub StripHeaderAndFooter()
Dim fs As Object ''FileSystemObject
Dim tsIn As Object, tsOut As Object ''TextStream
Dim sFileIn As String, sFileOut As String
Dim aryFile As Variant

    sFileIn = "z:\docs\FileName.csv"
    sFileOut = "z:\docs\FileOut.csv"

    Set fs = CreateObject("Scripting.FileSystemObject")
    Set tsIn = fs.OpenTextFile(sFileIn, 1) ''ForReading

    sTmp = tsIn.ReadAll

    Set tsOut = fs.CreateTextFile(sFileOut, True) ''Overwrite
    aryFile = Split(sTmp, vbCrLf)

    ''Start at line 3 and end at last line -1
    For i = 3 To UBound(aryFile) - 1
        tsOut.WriteLine aryFile(i)
    Next

    tsOut.Close

    DoCmd.TransferText acImportDelim, , "NewCSV", sFileOut, False
End Sub

Edit re various comments

It is possible to import a text file manually into MS Access and this will allow you to choose you own cell delimiters and text delimiters. You need to choose External data from the menu, select your file and step through the wizard.

About importing and linking data and database objects -- Applies to: Microsoft Office Access 2003

Introduction to importing and exporting data -- Applies to: Microsoft Access 2010

Once you get the import working using the wizards, you can save an import specification and use it for you next DoCmd.TransferText as outlined by @Olivier Jacot-Descombes. This will allow you to have non-standard delimiters such as semi colon and single-quoted text.

The quickest fix would be to explicitly use the jQuery $ from the global context (which has been extended with your $.modal() because you referenced that in your script tag when you did ):

  window.$('#scheduleentry-modal').modal('show') // to show 
  window.$('#scheduleentry-modal').modal('hide') // to hide

so this is how you can about it on react

import React, { Component } from 'react';

export default Modal extends Component {
    componentDidMount() {
        window.$('#Modal').modal('show');
    }

    handleClose() {
        window.$('#Modal').modal('hide');
    }

    render() {
        <
        div className = 'modal fade'
        id = 'ModalCenter'
        tabIndex = '-1'
        role = 'dialog'
        aria - labelledby = 'ModalCenterTitle'
        data - backdrop = 'static'
        aria - hidden = 'true' >
            <
            div className = 'modal-dialog modal-dialog-centered'
        role = 'document' >
            <
            div className = 'modal-content' >
            // ...your modal body
            <
            button
        type = 'button'
        className = 'btn btn-secondary'
        onClick = {
                this.handleClose
            } >
            Close <
            /button> < /
        div > <
            /div> < /
        div >
    }
}

for python3 use subprocess

You're thinking too much in pure Javascript. Get rid of your listeners on those React lifecycle methods and use event.key instead of event.keyCode (because this is not a JS event object, it is a React SyntheticEvent). Your entire component could be as simple as this (assuming you haven't bound your methods in a constructor).

onKeyPressed(e) {
  console.log(e.key);
}

render() {
  let player = this.props.boards.dungeons[this.props.boards.currentBoard].player;
  return (
    <div 
      className="player"
      style={{ position: "absolute" }}
      onKeyDown={this.onKeyPressed}
    >
      <div className="light-circle">
        <div className="image-wrapper">
          <img src={IMG_URL+player.img} />
        </div>
      </div>
    </div>
  )
}

Just to give you an another option, you could use https://sourceforge.net/projects/dd2vmdk/ as well. dd2vmdk is a *nix-based program that allows you to mount raw disk images (created by dd, dcfldd, dc3dd, ftk imager, etc) by taking the raw image, analyzing the master boot record (physical sector 0), and getting specific information that is need to create a vmdk file.

Personally, imo Qemu and the Zapotek's raw2vmdk tools are the best overall options to convert dd to vmdks.

apt-get install php7.3-mbstring solved the issue on ubuntu, php version is php-fpm 7.3

Try this:

<img v-bind:src="'/media/avatars/' + joke.avatar" /> 

Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

joke: {
  avatar: 'image.jpg'
}

try this way .eregi("[^A-Za-z0-9.]", $value)

This means that you are doing a foreach on something that is not an array.

Check out all your foreach statements, and look if the thing before the as, to make sure it is actually an array. Use var_dump to dump it.

Then fix the one where it isn't an array.

How to reproduce this error:

<?php
$skipper = "abcd";
foreach ($skipper as $item){       //the warning happens on this line.
    print "ok";
}
?>

Make sure $skipper is an array.

I had this identical problem, I was using django-rest-knox for authentication tokens. It turns out that nothing was wrong with my fetch method which looked like this:

...
    let headers = {"Content-Type": "application/json"};
    if (token) {
      headers["Authorization"] = `Token ${token}`;
    }
    return fetch("/api/instruments/", {headers,})
      .then(res => {
...

I was running apache.

What solved this problem for me was changing WSGIPassAuthorization to 'On' in wsgi.conf.

I had a Django app deployed on AWS EC2, and I used Elastic Beanstalk to manage my application, so in the django.config, I did this:

container_commands:
  01wsgipass:
    command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf'

Hmmm $array = json_decode($json, true); will make your string an array which is easy to print nicely with print_r($array, true);

But if you really want to prettify your json... Check this out

I could install app on Nexus, but couldn't on Samsung. Nothing helped me except the change of the USB cable.

I had similar problem with the data frame:

group time weight.loss
1 Control  wl1    4.500000
2    Diet  wl1    5.333333
3  DietEx  wl1    6.200000
4 Control  wl2    3.333333
5    Diet  wl2    3.916667
6  DietEx  wl2    6.100000
7 Control  wl3    2.083333
8    Diet  wl3    2.250000
9  DietEx  wl3    2.200000

I think the variable for x axis should be numeric, so that geom_line knows how to connect the points to draw the line.

after I change the 2nd column to numeric:

 group time weight.loss
1 Control    1    4.500000
2    Diet    1    5.333333
3  DietEx    1    6.200000
4 Control    2    3.333333
5    Diet    2    3.916667
6  DietEx    2    6.100000
7 Control    3    2.083333
8    Diet    3    2.250000
9  DietEx    3    2.200000

then it works.

$("form > .form-group > i").click(function(){
    $('#icon').toggleClass('fa-eye fa-eye-slash');

    if($('#icon').hasClass('fa-eye')){
        $('#Password1').attr('type','text');
    } else {
        $('#Password1').attr('type','password');
    }
});

A combination of componentDidMount and componentDidUpdate will get the job done in a code with class components. But if you're writing code in total functional components the Effect Hook would do a great job it's the same as componentDidMount and componentDidUpdate.

import React, { useState, useEffect } from 'react';

function Example() {
  const [count, setCount] = useState(0);

  // Similar to componentDidMount and componentDidUpdate:
  useEffect(() => {
    // Update the document title using the browser API
    document.title = `You clicked ${count} times`;
  });

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}

Create a .vbs file with this code:

CreateObject("Wscript.Shell").Run "your_batch.bat",0,True

This .vbs will run your_batch.bat hidden.

Works fine for me.

file_get_contents() usually has permission issues. To avoid them, use:

function get_xml_from_url($url){
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

    $xmlstr = curl_exec($ch);
    curl_close($ch);

    return $xmlstr;
}

Example:

$xmlstr = get_xml_from_url('http://www.camara.gov.br/SitCamaraWS/Deputados.asmx/ObterDeputados');
$xmlobj = new SimpleXMLElement($xmlstr);
$xmlobj = (array)$xmlobj;//optional

As Kris mentions, you can use the $resource service to interact with the server, but I get the impression you are beginning your journey with Angular - I was there last week - so I recommend to start experimenting directly with the $http service. In this case you can call its get method.

If you have the following JSON

[{ "text":"learn angular", "done":true },
 { "text":"build an angular app", "done":false},
 { "text":"something", "done":false },
 { "text":"another todo", "done":true }]

You can load it like this

var App = angular.module('App', []);

App.controller('TodoCtrl', function($scope, $http) {
  $http.get('todos.json')
       .then(function(res){
          $scope.todos = res.data;                
        });
});

The get method returns a promise object which first argument is a success callback and the second an error callback.

When you add $http as a parameter of a function Angular does it magic and injects the $http resource into your controller.

I've put some examples here

Using regex to parse html is not recommended

regex is used for regularly occurring patterns.html is not regular with it's format(except xhtml).For example html files are valid even if you don't have a closing tag!This could break your code.

Use an html parser like htmlagilitypack

You can use this code to retrieve all href's in anchor tag using HtmlAgilityPack

HtmlDocument doc = new HtmlDocument();
doc.Load(yourStream);

var hrefList = doc.DocumentNode.SelectNodes("//a")
                  .Select(p => p.GetAttributeValue("href", "not found"))
                  .ToList();

hrefList contains all href`s

If your key has a fixed number of digits, you should probably store as text rather than as numeric data. You can use the converters argument or read_excel for this.

Or, if this does not work, just manipulate your data once it's read into your dataframe:

df['key_zfill'] = df['key'].astype(str).str.zfill(4)

  names   key key_zfill
0   abc     5      0005
1   def  4962      4962
2   ghi   300      0300
3   jkl    14      0014
4   mno    20      0020

Run this convenient SQL query to see running MySQL queries. It can be run from any environment you like, whenever you like, without any code changes or overheads. It may require some MySQL permissions configuration, but for me it just runs without any special setup.

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE COMMAND != 'Sleep';

The only catch is that you often miss queries which execute very quickly, so it is most useful for longer-running queries or when the MySQL server has queries which are backing up - in my experience this is exactly the time when I want to view "live" queries.

You can also add conditions to make it more specific just any SQL query.

e.g. Shows all queries running for 5 seconds or more:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE COMMAND != 'Sleep' AND TIME >= 5;

e.g. Show all running UPDATEs:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE COMMAND != 'Sleep' AND INFO LIKE '%UPDATE %';

For full details see: http://dev.mysql.com/doc/refman/5.1/en/processlist-table.html

You could also use:

nvidia-smi | grep "CUDA Version:" 

To retrieve the explicit line.

I'm surprised nobody pointed out JSON's [] method, which makes it very easy and transparent to decode and encode from/to JSON.

If object is string-like, parse the string and return the parsed result as a Ruby data structure. Otherwise generate a JSON text from the Ruby data structure object and return it.

Consider this:

require 'json'

hash = {"val":"test","val1":"test1","val2":"test2"} # => {:val=>"test", :val1=>"test1", :val2=>"test2"}
str = JSON[hash] # => "{\"val\":\"test\",\"val1\":\"test1\",\"val2\":\"test2\"}"

str now contains the JSON encoded hash.

It's easy to reverse it using:

JSON[str] # => {"val"=>"test", "val1"=>"test1", "val2"=>"test2"}

Custom objects need to_s defined for the class, and inside it convert the object to a Hash then use to_json on it.

For anyone who might be curious about the naming, I'm just going to add that it's probably called "Found" because the main resource(e.g., a private web page) the user intends to receive is not available at that moment(e.g., the user has not proved their identity yet), so instead the server has found a new resource that the user can receive(which is a login page in the most common use case).

Also it's "getting lost and found" in the hide-and-seek manner, meaning a lost resource under a 302 status is only lost temporarily, it is not supposed to be lost forever(unless a player has some bad intentions;)).

You can do as yAnTar advised

ALTER TABLE TABLE_NAME ADD Id INT AUTO_INCREMENT PRIMARY KEY

OR

You can add a constraint

ALTER TABLE TABLE_NAME ADD CONSTRAINT constr_ID UNIQUE (user_id, game_id, date, time)

But I think to not lose your existing data, you can add an indentity column and then make a composite key.

I think you mean to update it back to the OLD password, when the NEW one is not supplied.

DROP TRIGGER IF EXISTS upd_user;

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '') THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

However, this means a user can never blank out a password.

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '' OR NEW.password = OLD.password) THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

not need to run queries to sidable FKs on sql. If you have a FK from table A to B, you should:

• delete data from table A
• delete data from table B
• insert data on B
• insert data on A

You can also tell the destination not to check constraints

                drawerLayout,
                toolbar,
                R.string.open,
                R.string.close
        )

        {
            public void onDrawerClosed(View view)
            {
                super.onDrawerClosed(view);
                invalidateOptionsMenu();

                invalidateOptionsMenu();
                syncState();
            }
        };
        drawerLayout.setDrawerListener(actionBarDrawerToggle);

        //Set the custom toolbar
        if (toolbar != null){
            setSupportActionBar(toolbar);

JObject implements IDictionary<string, JToken>, so you can use:

IDictionary<string, JToken> dictionary = x;
if (dictionary.ContainsKey("error_msg"))

... or you could use TryGetValue. It implements both methods using explicit interface implementation, so you can't use them without first converting to IDictionary<string, JToken> though.

This is a limitation of XmlSerializer. Note that BinaryFormatter and DataContractSerializer do not require this - they can create an uninitialized object out of the ether and initialize it during deserialization.

Since you are using xml, you might consider using DataContractSerializer and marking your class with [DataContract]/[DataMember], but note that this changes the schema (for example, there is no equivalent of [XmlAttribute] - everything becomes elements).

Update: if you really want to know, BinaryFormatter et al use FormatterServices.GetUninitializedObject() to create the object without invoking the constructor. Probably dangerous; I don't recommend using it too often ;-p See also the remarks on MSDN:

Because the new instance of the object is initialized to zero and no constructors are run, the object might not represent a state that is regarded as valid by that object. The current method should only be used for deserialization when the user intends to immediately populate all fields. It does not create an uninitialized string, since creating an empty instance of an immutable type serves no purpose.

I have my own serialization engine, but I don't intend making it use FormatterServices; I quite like knowing that a constructor (any constructor) has actually executed.

ArrayList<String[]> action = new ArrayList<String[]>();

Don't need String[2];

How about trying:

select * from 'test_table'
where end_date < CAST('2009-12-15' AS DATE)
or start_date > CAST('2010-01-02' AS DATE)

which will return all date ranges which do not overlap your date range at all.

You need to add the column with a default of null, then alter the column to have default now().

ALTER TABLE mytable ADD COLUMN created_at TIMESTAMP;
ALTER TABLE mytable ALTER COLUMN created_at SET DEFAULT now();

You can use WebClient class to connect to the network driver using credentials. Include the below namespace:

using System.Net;

WebClient request = new WebClient();
request.Credentials = new NetworkCredential("domain\username", "password");
string[] theFolders = Directory.GetDirectories(@"\\computer\share");

320

And the segments look like this

{64}@{255}

64 + 1 + 255 = 320

A sidenote to consider, you can store arrays in Postgres.

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

    var button_beg = '<button id="button" onclick="showhide()">', button_end = '</button>';
    var show_button = 'Show', hide_button = 'Hide';
    function showhide() {
        var div = document.getElementById( "hide_show" );
        var showhide = document.getElementById( "showhide" );
        if ( div.style.display !== "none" ) {
            div.style.display = "none";
            button = show_button;
            showhide.innerHTML = button_beg + button + button_end;
        } else {
            div.style.display = "block";
            button = hide_button;
            showhide.innerHTML = button_beg + button + button_end;
        }
    }
    function setup_button( status ) {
        if ( status == 'show' ) {
            button = hide_button;
        } else {
            button = show_button;
        }
        var showhide = document.getElementById( "showhide" );
        showhide.innerHTML = button_beg + button + button_end;
    }
    window.onload = function () {
        setup_button( 'hide' );
        showhide(); // if setup_button is set to 'show' comment this line
    }

You can, under certain circumstances.

But the fact that you consider this is a strong sign that there is something wrong with your architecture: Primary keys should be pure technical and carry no business meaning whatsoever. So there should never be the need to change them.

This will add a centered border to the left of the cell that is 80% the height of the cell. You can reference the full border-image documentation here.

table td {
    border-image: linear-gradient(transparent 10%, blue 10% 90%, transparent 90%) 0 0 0 1 / 3px;
}

Create your own conversion function that applies the needed math, and invoke those instead. http://en.wikipedia.org/wiki/Radian#Conversion_between_radians_and_degrees

you can use this bash script

convert.sh

and run

./convert.sh -f example/mycsvfile.csv

You need to process the image beforehand, to make a centered and stretched image. Try this:

UIGraphicsBeginImageContext(self.view.frame.size);
[[UIImage imageNamed:@"image.png"] drawInRect:self.view.bounds];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

self.view.backgroundColor = [UIColor colorWithPatternImage:image];

A)

Object* o;
o = new Object();

`` B)

Object* o = new Object();

I think A and B has no difference. In both the cases o is a pointer to class Object. statement new Object() creates an object of class Object from heap memory. Assignment statement assigns the address of allocated memory to pointer o.

One thing I would like to mention that size of allocated memory from heap is always the sizeof(Object) not sizeof(Object) + sizeof(void *).

You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.

Example:

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      window.location.href = 'https://website.com/my-account';
    }
  };
  xhttp.open("POST", "demo_post.asp", true);
  xhttp.send();

Added to Alister, you can edit the crontab usually (not always the case) by entering crontab -e in a ssh session on the server.

The stars represent (* means every of this unit):

[Minute] [Hour] [Day] [Month] [Day of week (0 =sunday to 6 =saturday)] [Command]

You could read some more about this here.

In the specific case of a Rails action (as opposed to the general case of getting the current method name) you can use params[:action]

Alternatively you might want to look into customising the Rails log format so that the action/method name is included by the format rather than it being in your log message.

Use SimpleDateFormat as aix suggested to format the current time into a string. You should use a format that does not include / characters etc. I would suggest something like yyyyMMddhhmm

Using mvn eclipse:eclipse will just generate general eclipse configuration files, this is fine if you have a simple project; but in case of a web-based project such as servlet/jsp you need to manually add Java EE features to eclipse (WTP).

To make the project runnable via eclipse servers portion, Configure Apache for Eclipse: Download and unzip Apache Tomcat somewhere. In Eclipse Windows -> Preferences -> Servers -> Runtime Environments add (Create local server), select your version of Tomcat, Next, Browse to the directory of the Tomcat you unzipped, click Finish.

Window -> Show View -> Servers Add the project to the server list

By the power of Google I found a blogpost from 2007 which gives the following regex that matches string which don't contains a certain substring:

^((?!my string).)*$

It works as follows: it looks for zero or more (*) characters (.) which do not begin (?! - negative lookahead) your string and it stipulates that the entire string must be made up of such characters (by using the ^ and $ anchors). Or to put it an other way:

The entire string must be made up of characters which do not begin a given string, which means that the string doesn't contain the given substring.

I strongly recommend the use of getopt.

If you want help to print out for your options then take a look at GetOptionKit.

For PHP code:

<?php
error_reporting(E_ALL & ~E_NOTICE);

For php.ini config:

error_reporting = E_ALL & ~E_NOTICE

You can get to the root from within each site using $_SERVER['DOCUMENT_ROOT']. For testing ONLY you can echo out the path to make sure it's working, if you do it the right way. You NEVER want to show the local server paths for things like includes and requires.

Site 1

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/';

Includes under site one would be at:

echo $_SERVER['DOCUMENT_ROOT'].'/includes/'; // should be '/main_web_folder/includes/';

Site 2

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/blog/';

The actual code to access includes from site1 inside of site2 you would say:

include($_SERVER['DOCUMENT_ROOT'].'/../includes/file_from_site_1.php');

It will only use the relative path of the file executing the query if you try to access it by excluding the document root and the root slash:

 //(not as fool-proof or non-platform specific)
 include('../includes/file_from_site_1.php');

Included paths have no place in code on the front end (live) of the site anywhere, and should be secured and used in production environments only.

Additionally for URLs on the site itself you can make them relative to the domain. Browsers will automatically fill in the rest because they know which page they are looking at. So instead of:

<a href='http://www.__domain__name__here__.com/contact/'>Contact</a>

You should use:

<a href='/contact/'>Contact</a>

For good SEO you'll want to make sure that the URLs for the blog do not exist in the other domain, otherwise it may be marked as a duplicate site. With that being said you might also want to add a line to your robots.txt file for ONLY site1:

User-agent: *
Disallow: /blog/

Other possibilities:

Look up your IP address and include this snippet of code:

function is_dev(){
  //use the external IP from Google.
  //If you're hosting locally it's 127.0.01 unless you've changed it.
  $ip_address='xxx.xxx.xxx.xxx';

  if ($_SERVER['REMOTE_ADDR']==$ip_address){
     return true;
  } else {
     return false;
  } 
}

if(is_dev()){
    echo $_SERVER['DOCUMENT_ROOT'];       
}

Remember if your ISP changes your IP, as in you have a DCHP Dynamic IP, you'll need to change the IP in that file to see the results. I would put that file in an include, then require it on pages for debugging.

If you're okay with modern methods like using the browser console log you could do this instead and view it in the browser's debugging interface:

if(is_dev()){
    echo "<script>".PHP_EOL;
    echo "console.log('".$_SERVER['DOCUMENT_ROOT']."');".PHP_EOL;
    echo "</script>".PHP_EOL;       
}

The following worked for me:

ol {
  list-style-type: none;
  counter-reset: item;
  margin: 0;
  padding: 0;
}

ol > li {
  display: table;
  counter-increment: item;
  margin-bottom: 0.6em;
}

ol > li:before {
  content: counters(item, ".") ") ";
  display: table-cell;
  padding-right: 0.6em;
}

li ol > li {
  margin: 0;
}

li ol > li:before {
  content: counters(item, ".") ") ";
}

In pymongo you can update with:
mycollection.update({'_id':mongo_id}, {"$set": post}, upsert=False)
Upsert parameter will insert instead of updating if the post is not found in the database.
Documentation is available at mongodb site.

UPDATE For version > 3 use update_one instead of update:

mycollection.update_one({'_id':mongo_id}, {"$set": post}, upsert=False)

val array2 = array :+ 4
//Array(1, 2, 3, 4)

Works also "reversed":

val array2 = 4 +: array
Array(4, 1, 2, 3)

There is also an "in-place" version:

var array = Array( 1, 2, 3 )
array +:= 4
//Array(4, 1, 2, 3)
array :+= 0
//Array(4, 1, 2, 3, 0)

Let's say that accessing http://thesite.com/ said that the WSDL address is: http://thesite.com/PortalIntegratorService.svc?wsdl

$client = new SoapClient('http://thesite.com/PortalIntegratorService.svc?wsdl');
$result = $client->authenticateLogin(array('LoginId' => 12345));
if (!empty($result->authenticateLoginResult->RequestStatus)
    && !empty($result->authenticateLoginResult->UserName)) {
    echo 'The username is: '.$result->authenticateLoginResult->UserName;
}

As you can see, the items specified in the XML are used in the PHP code though the LoginId value can be changed.

Just get the Eclipse Memory Analyzer. There's nothing better out there and it's free.

JHAT is only usable for "toy applications"

why not just

You might like to consider ADO - a worksheet or range can be used as a table.

Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adPersistXML = 1

Set cn = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.Recordset")

''It wuld probably be better to use the proper name, but this is
''convenient for notes
strFile = Workbooks(1).FullName

''Note HDR=Yes, so you can use the names in the first row of the set
''to refer to columns, note also that you will need a different connection
''string for >=2007
strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strFile _
        & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";"


cn.Open strCon
rs.Open "Select * from [Sheet1$]", cn, adOpenStatic, adLockOptimistic

If Not rs.EOF Then
    rs.MoveFirst
    rs.Save "C:\Docs\Table1.xml", adPersistXML
End If

rs.Close
cn.Close

This is for future readers. I found that the simplest method for me was to use Visual Studio -> Tools -> External Tools. More details in this answer.

Easier to use and good debugging tools.

You can use header to send the right Content-type :

header('Content-Type: ' . $type);

And readfile to output the content of the image :

readfile($file);

And maybe (probably not necessary, but, just in case) you'll have to send the Content-Length header too :

header('Content-Length: ' . filesize($file));

Note : make sure you don't output anything else than your image data (no white space, for instance), or it will no longer be a valid image.

Use Jackson-annotations.jar will solve the problem, as it worked for me.

This is the correct way:

public class JSONParser extends AsyncTask <String, Void, String>{

            HttpResponse getResponse = httpClient.execute(httpPost);
           final int statusCode = getResponse.getStatusLine().getStatusCode();

           if (statusCode != HttpStatus.SC_OK) {

        e.printStackTrace();
    } catch (IOException e) {
        Log.d("IO", e.getMessage().toString());

    }

    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        json = sb.toString();
    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }

    // try parse the string to a JSON object
    try {
        jObj = new JSONObject(json);
    } catch (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
    }

    // return JSON String
    return jObj;


}
protected void onPostExecute(String page)

}

To call it (from main):

mJSONParser = new JSONParser();
mJSONParser.execute();

It looks necessary to put a SET IDENTITY_INSERT Database.dbo.Baskets ON; before every SQL INSERT sending batch.

You can send several INSERT ... VALUES ... commands started with one SET IDENTITY_INSERT ... ON; string at the beginning. Just don't put any batch separator between.

I don't know why the SET IDENTITY_INSERT ... ON stops working after the sending block (for ex.: .ExecuteNonQuery() in C#). I had to put SET IDENTITY_INSERT ... ON; again at the beginning of next SQL command string.

Here's another possible cause -- my form was submitting to domain.com without the WWW. and I had set up an automatic redirect to add the "WWW." The $_POST array was getting emptied in the process. So to fix it all I had to do was submit to www.domain.com

I have a pretty detailed example of how to paginate with a RecyclerView. At a high level, I have a set PAGE_SIZE , lets say 30. So I request 30 items and if I get 30 back then I request the next page. If I get less than 30 items I flag a variable to indicate that the last page has been reached and then I stop requesting for more pages. Check it out and let me know what you think.

dF: that's pretty cool... I didn't know that I could access the fields in a class using dict.

Mark: the situations that I wish I had this are precisely when I want a tuple but nothing as "heavy" as a dictionary.

You can access the fields of a class using a dictionary because the fields of a class, its methods and all its properties are stored internally using dicts (at least in CPython).

...Which leads us to your second comment. Believing that Python dicts are "heavy" is an extremely non-pythonistic concept. And reading such comments kills my Python Zen. That's not good.

You see, when you declare a class you are actually creating a pretty complex wrapper around a dictionary - so, if anything, you are adding more overhead than by using a simple dictionary. An overhead which, by the way, is meaningless in any case. If you are working on performance critical applications, use C or something.

You can do EXISTS in Oracle PL/SQL.

You can do the following:

DECLARE
    n_rowExist NUMBER := 0;
BEGIN
    SELECT CASE WHEN EXISTS (
      SELECT 1
      FROM person
      WHERE ID = 10
    ) THEN 1 ELSE 0 INTO n_rowExist END FROM DUAL;
    
    IF n_rowExist = 1 THEN
       -- do things when it exists
    ELSE
       -- do things when it doesn't exist
    END IF;

END;
/

Explanation:

In the query nested where it starts with SELECT CASE WHEN EXISTS and after the parenthesis (SELECT 1 FROM person WHERE ID = 10) it will return a result if it finds a person of ID of 10. If the there's a result on the query then it will assign the value of 1 otherwise it will assign the value of 0 to n_rowExist variable. Afterwards, the if statement checks if the value returned equals to 1 then is true otherwise it will be 0 = 1 and that is false.

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

I've found the Sync with Active Document button in the solution explorer to be the the most effective (this may be a vs2013 feature!)

I have the same problem, and i realize that. When we create adapter and set it to listview, listview will point to object somewhere in memory which adapter hold, data in this object will show in listview.

adapter = new CustomAdapter(data);
listview.setadapter(adapter);

if we create an object for adapter with another data again and notifydatasetchanged():

adapter = new CustomAdapter(anotherdata);
adapter.notifyDataSetChanged();

this will do not affect to data in listview because the list is pointing to different object, this object does not know anything about new object in adapter, and notifyDataSetChanged() affect nothing. So we should change data in object and avoid to create a new object again for adapter

I have referred this github post and I have set the three layouts for three fragment pages in bottom tab bar.

FourButtonsActivity.java:

bottomBar.setFragmentItems(getSupportFragmentManager(), R.id.fragmentContainer,
            new BottomBarFragment(LibraryFragment.newInstance(R.layout.library_fragment_layout), R.drawable.ic_update_white_24dp, "Recents"),
            new BottomBarFragment(PhotoEffectFragment.newInstance(R.layout.photo_effect_fragment), R.drawable.ic_local_dining_white_24dp, "Food"),
            new BottomBarFragment(VideoFragment.newInstance(R.layout.video_layout), R.drawable.ic_favorite_white_24dp, "Favorites")

    );

To set the badge count :

  BottomBarBadge unreadMessages = bottomBar.makeBadgeForTabAt(1, "#E91E63", 4);
  unreadMessages.show();
  unreadMessages.setCount(4);
  unreadMessages.setAnimationDuration(200);
  unreadMessages.setAutoShowAfterUnSelection(true);

Here's a pure JavaScript function which will simulate a click (or any mouse event) on a target element:

function simulatedClick(target, options) {

  var event = target.ownerDocument.createEvent('MouseEvents'),
      options = options || {},
      opts = { // These are the default values, set up for un-modified left clicks
        type: 'click',
        canBubble: true,
        cancelable: true,
        view: target.ownerDocument.defaultView,
        detail: 1,
        screenX: 0, //The coordinates within the entire page
        screenY: 0,
        clientX: 0, //The coordinates within the viewport
        clientY: 0,
        ctrlKey: false,
        altKey: false,
        shiftKey: false,
        metaKey: false, //I *think* 'meta' is 'Cmd/Apple' on Mac, and 'Windows key' on Win. Not sure, though!
        button: 0, //0 = left, 1 = middle, 2 = right
        relatedTarget: null,
      };

  //Merge the options with the defaults
  for (var key in options) {
    if (options.hasOwnProperty(key)) {
      opts[key] = options[key];
    }
  }

  //Pass in the options
  event.initMouseEvent(
      opts.type,
      opts.canBubble,
      opts.cancelable,
      opts.view,
      opts.detail,
      opts.screenX,
      opts.screenY,
      opts.clientX,
      opts.clientY,
      opts.ctrlKey,
      opts.altKey,
      opts.shiftKey,
      opts.metaKey,
      opts.button,
      opts.relatedTarget
  );

  //Fire the event
  target.dispatchEvent(event);
}

Here's a working example: http://www.spookandpuff.com/examples/clickSimulation.html

You can simulate a click on any element in the DOM. Something like simulatedClick(document.getElementById('yourButtonId')) would work.

You can pass in an object into options to override the defaults (to simulate which mouse button you want, whether Shift/Alt/Ctrl are held, etc. The options it accepts are based on the MouseEvents API.

I've tested in Firefox, Safari and Chrome. Internet Explorer might need special treatment, I'm not sure.

I use this command:

netstat -tulpn | grep LISTEN

You can have a clean output that shows process id and ports that's listening on

After JAVAEE8 published , now you can use the new JAVAEE API JSON-B (JSR367)

Maven dependency :

<dependency>
    <groupId>javax.json.bind</groupId>

</dependency>

Here is some code snapshot :

Jsonb jsonb = JsonbBuilder.create();
// Two important API : toJson fromJson
String result = jsonb.toJson(listaDePontos);

JSON-P is also updated to 1.1 and more easy to use. JSON-P 1.1 (JSR374)

Maven dependency :

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.json</artifactId>

Here is the runnable code snapshot :

String data = "{\"name\":\"Json\","
                + "\"age\": 29,"
                + " \"phoneNumber\": [10000,12000],"

        JsonObject original = Json.createReader(new StringReader(data)).readObject();
        /**getValue*/
        JsonPointer pAge = Json.createPointer("/age");
        JsonValue v = pAge.getValue(original);

        JsonPointer pPhone = Json.createPointer("/phoneNumber/1");
        System.out.println("phoneNumber 2 is " + pPhone.getValue(original).toString());

You need a table variable:

declare @values table
(
    Value varchar(1000)
)

insert into @values values ('A')
insert into @values values ('B')
insert into @values values ('C')

select blah
from foo
where myField in (select value from @values)

If you're OK with a JavaScript solution, there's a jQuery plug-in to do this in a cross-browser fashion - see http://azgtech.wordpress.com/2009/07/26/text-overflow-ellipsis-for-firefox-via-jquery/

If I correctly got what you want:

$rules = ['Fno' => 'digits_between:2,5', 'Lno' => 'numeric|min:2'];

or

$rules = ['Fno' => 'numeric|min:2|max:5', 'Lno' => 'numeric|min:2'];

For all the available rules: http://laravel.com/docs/4.2/validation#available-validation-rules

digits_between :min,max

The field under validation must have a length between the given min and max.

numeric

The field under validation must have a numeric value.

max:value

The field under validation must be less than or equal to a maximum value. Strings, numerics, and files are evaluated in the same fashion as the size rule.

min:value

The field under validation must have a minimum value. Strings, numerics, and files are evaluated in the same fashion as the size rule.

When doing this inside an except ...: block it will automatically use the current exception. See http://docs.python.org/library/traceback.html for more information.

There is a product from http://www.shunra.com called VE Desktop which can be used to simulate varying network conditions. It allows you to tweak latencies, bandwidth and packetloss with a simple UI. Only caveat is, its not free. Hope this helps.

That feature is called a common table expression http://msdn.microsoft.com/en-us/library/ms190766.aspx

You won't be able to do the exact thing in mySQL, the easiest thing would to probably make a view that mirrors that CTE and just select from the view. You can do it with subqueries, but that will perform really poorly. If you run into any CTEs that do recursion, I don't know how you'd be able to recreate that without using stored procedures.

EDIT: As I said in my comment, that example you posted has no need for a CTE, so you must have simplified it for the question since it can be just written as

SELECT article.*, userinfo.*, category.* FROM question
     INNER JOIN userinfo ON userinfo.user_userid=article.article_ownerid
     INNER JOIN category ON article.article_categoryid=category.catid
     WHERE article.article_isdeleted = 0
 ORDER BY article_date DESC Limit 1, 3

The above method works good.

Another method (I am assuming web here) is to create your page. Add controls to the page. Then while in design mode go to: Tools > Generate Local Resource. A resource file will automatically appear in the solution with all the controls in the page mapped in the resource file.

To create resources for other languages, append the 4 character language to the end of the file name, before the extension (Account.aspx.en-US.resx, Account.aspx.es-ES.resx...etc).

To retrieve specific entries in the code-behind, simply call this method: GetLocalResourceObject([resource entry key/name]).

This works for me.

dataFrame = pd.dataFrame(data = np.c_[ [iris['data'],iris['target'] ],
columns=iris['feature_names'].tolist() + ['target'])

You would use the read.csv function; for example:

dat = read.csv("spam.csv", header = TRUE)

You can also reference this tutorial for more details.

Note: make sure the .csv file to read is in your working directory (using getwd()) or specify the right path to file. If you want, you can set the current directory using setwd.

If you want to set a custom drawable file use this code snippet

fun setCustomStatusBar(){
    if (Build.VERSION.SDK_INT >= 21) {
        val decor = window.decorView
        decor.viewTreeObserver.addOnPreDrawListener(object :
            ViewTreeObserver.OnPreDrawListener {
            override fun onPreDraw(): Boolean {
                decor.viewTreeObserver.removeOnPreDrawListener(this)
                val statusBar = decor.findViewById<View> 
                  (android.R.id.statusBarBackground)
                statusBar.setBackgroundResource(R.drawable.bg_statusbar)
                return true
            }
        })
    }
}

With newer Go versions, reading/writing to/from file is easy. To read from a file:

package main

import (
    "fmt"
    "io/ioutil"
)

func main() {
    data, err := ioutil.ReadFile("text.txt")
    if err != nil {
        return
    }
    fmt.Println(string(data))
}

To write to a file:

package main

import "os"

func main() {
    file, err := os.Create("text.txt")
    if err != nil {
        return
    }
    defer file.Close()

    file.WriteString("test\nhello")
}

This will overwrite the content of a file (create a new file if it was not there).

Answers above look incomplete as they are talking from css point of view only.

positioning of svg within viewport is affected by two svg attributes

1. viewBox: defines the rectangle area for svg to cover.
2. preserveAspectRatio: defined where to place the viewBox wrt viewport and how to strech it if viewport changes.

Follow this link from codepen for detailed description

<svg viewBox="70 160 800 190" preserveAspectRatio="xMaxYMax meet">

To position block elements to the center (works in IE9 and above), needs a wrapper div:

.vcontainer {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
  -webkit-transform: translateY(-50%);
}

The best I've seen so far is HtmlCleaner:

HtmlCleaner is open-source HTML parser written in Java. HTML found on Web is usually dirty, ill-formed and unsuitable for further processing. For any serious consumption of such documents, it is necessary to first clean up the mess and bring the order to tags, attributes and ordinary text. For the given HTML document, HtmlCleaner reorders individual elements and produces well-formed XML. By default, it follows similar rules that the most of web browsers use in order to create Document Object Model. However, user may provide custom tag and rule set for tag filtering and balancing.

With HtmlCleaner you can locate any element using XPath.

For other html parsers see this SO question.

Encode.php

<h1>Encode HTML CODE</h1>

<form action='htmlencodeoutput.php' method='post'>

You can encode HTML like this .

You can also open a required file through a prompt, This helps when you want to select file from different path and different file.

Sub openwb()
Dim wkbk As Workbook
Dim NewFile As Variant

NewFile = Application.GetOpenFilename("microsoft excel files (*.xlsm*), *.xlsm*")

If NewFile <> False Then
Set wkbk = Workbooks.Open(NewFile)
End If
End Sub

In my view, "Explicit is always better than implicit." Because at some point, you may got confused with this increments statement y+ = x++ + ++y. A good programmer always makes his or her code more readable.

To set value in JavaScript using set attribute , for selected option tag

var newvalue = 10;
var x = document.getElementById("optionid").selectedIndex;
    document.getElementById("optionid")[x].setAttribute('value', newvalue);

In reply to Dimitrys answer but using Ajax.BeginForm the following works at least with MVC >5 (4 not tested).

1. write a model as shown in the other answers,

2. In the "parent view" you will probably use a table to show the data. Model should be an ienumerable. I assume, the model has an id-property. Howeverm below the template, a placeholder for the modal and corresponding javascript

   <table>
   @foreach (var item in Model)
   {
       <tr> <td id="[email protected]"> 
           @Html.Partial("dataRowView", item)
       </td> </tr>
   }
   </table>
   
   <div class="modal fade" id="editor-container" tabindex="-1" 
        role="dialog" aria-labelledby="editor-title">
       <div class="modal-dialog modal-lg" role="document">
           <div class="modal-content" id="editor-content-container"></div>
       </div>
   </div> 
   
   <script type="text/javascript">
       $(function () {
           $('.editor-container').click(function () {
               var url = "/area/controller/MyEditAction";  
               var id = $(this).attr('data-id');  
               $.get(url + '/' + id, function (data) {
                   $('#editor-content-container').html(data);
                   $('#editor-container').modal('show');
               });
           });
       });
   
       function success(data,status,xhr) {
           $('#editor-container').modal('hide');
           $('#editor-content-container').html("");
       }
   
       function failure(xhr,status,error) {
           $('#editor-content-container').html(xhr.responseText);
           $('#editor-container').modal('show');
       }
   </script>
   

note the "editor-success-id" in data table rows.

3. The dataRowView is a partial containing the presentation of an model's item.

   @model ModelView
   @{
       var item = Model;
   }
   <div class="row">
           // some data 
           <button type="button" class="btn btn-danger editor-container" data-id="@item.Id">Edit</button>
   </div>
   

4. Write the partial view that is called by clicking on row's button (via JS $('.editor-container').click(function () ... ).

   @model Model
   <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal" aria-label="Close">
           <span aria-hidden="true">&times;</span>
       </button>
       <h4 class="modal-title" id="editor-title">Title</h4>
   </div>
   @using (Ajax.BeginForm("MyEditAction", "Controller", FormMethod.Post,
                       new AjaxOptions
                       {
                           InsertionMode = InsertionMode.Replace,
                           HttpMethod = "POST",
                           UpdateTargetId = "editor-success-" + @Model.Id,
                           OnSuccess = "success",
                           OnFailure = "failure",
                       }))
   {
       @Html.ValidationSummary()
       @Html.AntiForgeryToken()
       @Html.HiddenFor(model => model.Id)
       <div class="modal-body">
           <div class="form-horizontal">
               // Models input fields
           </div>
       </div>
       <div class="modal-footer">
           <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
           <button type="submit" class="btn btn-primary">Save</button>
       </div>
   }
   

This is where magic happens: in AjaxOptions, UpdateTargetId will replace the data row after editing, onfailure and onsuccess will control the modal.

This is, the modal will only close when editing was successful and there have been no errors, otherwise the modal will be displayed after the ajax-posting to display error messages, e.g. the validation summary.

But how to get ajaxform to know if there is an error? This is the controller part, just change response.statuscode as below in step 5:

5. the corresponding controller action method for the partial edit modal

   [HttpGet]
   public async Task<ActionResult> EditPartData(Guid? id)
   {
       // Find the data row and return the edit form
       Model input = await db.Models.FindAsync(id);
       return PartialView("EditModel", input);
   }
   
   [HttpPost, ValidateAntiForgeryToken]
   public async Task<ActionResult> MyEditAction([Bind(Include =
      "Id,Fields,...")] ModelView input)
   {
       if (TryValidateModel(input))
       {  
           // save changes, return new data row  
           // status code is something in 200-range
           db.Entry(input).State = EntityState.Modified;
           await db.SaveChangesAsync();
           return PartialView("dataRowView", (ModelView)input);
       }
   
       // set the "error status code" that will redisplay the modal
       Response.StatusCode = 400;
       // and return the edit form, that will be displayed as a 
       // modal again - including the modelstate errors!
       return PartialView("EditModel", (Model)input);
   }
   

This way, if an error occurs while editing Model data in a modal window, the error will be displayed in the modal with validationsummary methods of MVC; but if changes were committed successfully, the modified data table will be displayed and the modal window disappears.

Note: you get ajaxoptions working, you need to tell your bundles configuration to bind jquery.unobtrusive-ajax.js (may be installed by NuGet):

        bundles.Add(new ScriptBundle("~/bundles/jqueryajax").Include(
                    "~/Scripts/jquery.unobtrusive-ajax.js"));

Implicit is when you define your interface via a member on your class. Explicit is when you define methods within your class on the interface. I know that sounds confusing but here is what I mean: IList.CopyTo would be implicitly implemented as:

public void CopyTo(Array array, int index)
{
    throw new NotImplementedException();
}

and explicitly as:

void ICollection.CopyTo(Array array, int index)
{
    throw new NotImplementedException();
}

The difference is that implicit implementation allows you to access the interface through the class you created by casting the interface as that class and as the interface itself. Explicit implementation allows you to access the interface only by casting it as the interface itself.

MyClass myClass = new MyClass(); // Declared as concrete class
myclass.CopyTo //invalid with explicit
((IList)myClass).CopyTo //valid with explicit.

I use explicit primarily to keep the implementation clean, or when I need two implementations. Regardless, I rarely use it.

I am sure there are more reasons to use/not use explicit that others will post.

See the next post in this thread for excellent reasoning behind each.

One more way - just add a selected = "selected" attribute to the select markup and call select2 on it. It must take your selected value. No need for extra JavaScript. Like this :

Markup

<select class="select2">
   <option id="foo">Some Text</option>
   <option id="bar" selected="selected">Other Text</option>
</select>

JavaScript

$('select').select2(); //oh yes just this!

See fiddle : http://jsfiddle.net/6hZFU/

Edit: (Thanks, Jay Haase!)

If this doesn't work, try setting the val property of select2 to null, to clear the value, like this:

$('select').select2("val", null); //a lil' bit more :)

After this, it is simple enough to set val to "Whatever You Want".

Use ViewCompat.setBackground(view, background);

The constructor String(byte[] bytes) takes the bytes from the buffer and encodes them to characters.

It uses the platform default charset to encode bytes to characters. If you know, your file contains text, that is encoded in a different charset, you can use the String(byte[] bytes, String charsetName) to use the correct encoding (from bytes to characters).

For me the only thing that works is put in the activity in the manifest this atribute:

android:windowSoftInputMode="stateHidden|adjustPan"

To not show the keyboard when opening the activity and don't overlap the bottom of the view.

It is simple,for Example

-(void)applicationWillEnterForeground:(UIApplication *)application {

    NSLog(@"%s", __PRETTY_FUNCTION__);

}

Output: -[AppDelegate applicationWillEnterForeground:]

You can clean up a zombie process by killing its parent process with the following command:

kill -HUP $(ps -A -ostat,ppid | awk '{/[zZ]/{ print $2 }')

This is an API issue, you won't get this error if using Postman/Fielder to send HTTP requests to API. In case of browsers, for security purpose, they always send OPTIONS request/preflight to API before sending the actual requests (GET/POST/PUT/DELETE). Therefore, in case, the request method is OPTION, not only you need to add "Authorization" into "Access-Control-Allow-Headers", but you need to add "OPTIONS" into "Access-Control-allow-methods" as well. This was how I fixed:

if (context.Request.Method == "OPTIONS")
        {
            context.Response.Headers.Add("Access-Control-Allow-Origin", new[] { (string)context.Request.Headers["Origin"] });
            context.Response.Headers.Add("Access-Control-Allow-Headers", new[] { "Origin, X-Requested-With, Content-Type, Accept, Authorization" });
            context.Response.Headers.Add("Access-Control-Allow-Methods", new[] { "GET, POST, PUT, DELETE, OPTIONS" });
            context.Response.Headers.Add("Access-Control-Allow-Credentials", new[] { "true" });

        }

Interesting Python 2.x issue to keep in mind:

>>> import math
>>> math.ceil(4500/1000)
4.0
>>> math.ceil(4500/1000.0)
5.0

The problem is that dividing two ints in python produces another int and that's truncated before the ceiling call. You have to make one value a float (or cast) to get a correct result.

In javascript, the exact same code produces a different result:

console.log(Math.ceil(4500/1000));

In case of image stacks, I find it easier to use scikit-image to read, and matplotlib to show or save. I have handled 16-bit TIFF image stacks with the following code.

from skimage import io
import matplotlib.pyplot as plt

# read the image stack
img = io.imread('a_image.tif')
# show the image
plt.imshow(mol,cmap='gray')
plt.axis('off')
# save the image
plt.savefig('output.tif', transparent=True, dpi=300, bbox_inches="tight", pad_inches=0.0)

Both awk and sed are plenty fast, but if you think it matters feel free to use one of the following:

If the characters that you want to delete are always at the end of the string

echo '1234567890  *' | tr -d ' *'

If they can appear anywhere within the string and you only want to delete those at the end

echo '1234567890  *' | rev | cut -c 4- | rev

The man pages of all the commands will explain what's going on.

I think you should use sed, though.

Simply pass the sorted items from the dictionary to the plot() function. concentration.items() returns a list of tuples where each tuple contains a key from the dictionary and its corresponding value.

You can take advantage of list unpacking (with *) to pass the sorted data directly to zip, and then again to pass it into plot():

import matplotlib.pyplot as plt

concentration = {
    0: 0.19849878712984576,
    5000: 0.093917341754771386,
    10000: 0.075060643507712022,
    20000: 0.06673074282575861,
    30000: 0.057119318961966224,
    50000: 0.046134834546203485,
    100000: 0.032495766396631424,
    200000: 0.018536317451599615,
    500000: 0.0059499290585381479}

plt.plot(*zip(*sorted(concentration.items())))
plt.show()

sorted() sorts tuples in the order of the tuple's items so you don't need to specify a key function because the tuples returned by dict.item() already begin with the key value.
