You can use seismic. An example can be found here.

Try this background-position: center top;

This will do the trick for you.

If the array keys in your PHP array are not consecutive numbers, json_encode() must make the other construct an object since JavaScript arrays are always consecutively numerically indexed.

Use array_values() on the outer structure in PHP to discard the original array keys and replace them with zero-based consecutive numbering:

Example:

// Non-consecutive 3number keys are OK for PHP
// but not for a JavaScript array
$array = array(
  2 => array("Afghanistan", 32, 13),
  4 => array("Albania", 32, 12)
);

// array_values() removes the original keys and replaces
// with plain consecutive numbers
$out = array_values($array);
json_encode($out);
// [["Afghanistan", 32, 13], ["Albania", 32, 12]]

The easiest way is to use python-memcached-stats package, https://github.com/abstatic/python-memcached-stats

The keys() method should get you going.

Example -

from memcached_stats import MemcachedStats
mem = MemcachedStats()

mem.keys()
['key-1',
 'key-2',
 'key-3',
 ... ]

Note: Due to changes made to jQuery 1.9 and jQuery UI, this answer is no longer the correct one. Please see @stankovski's answer below.

You need to find the tab's index first (which is just its position in a list) and then specifically select the tab using jQuery UI's provided select event (tabs->select).

var index = $('#tabs ul').index($('#tabId'));
$('#tabs ul').tabs('select', index);

Update: BTW - I do realize that this is (ultimately) still selecting by index. But, it doesn't require that you know the specific position of the tabs (particularly when they are dynamically generated as asked in the question).

Just a heads up, while some of the answers posted here are correct (in a sense) one thing that you may need to do is go back to the root folder to delve down into the folder holding the image you want to set as the background. In other words, this code is correct in accomplishing your goal:

body {
    background-image:url('images/background.png');
    background-repeat:no-repeat;
    background-attachment:fixed;
}

But you may also need to add a little more to the code, like this:

body {
    background-image:url('../images/background.png');
    background-repeat:no-repeat;
    background-attachment:fixed;
}

The difference, as you can see, is that you may need to add “../” in front of the “images/background.png” call. This same rule also applies in HTML5 web pages. So if you are trying the first sample code listed here and you are still not getting the background image, try adding the “../” in front of “images”. Hope this helps .

If the file that this script lives in is executable, the hash-bang (#!) tells the operating system what interpreter to use to run the script. In this case it's /bin/sh, for example.

There's a Wikipedia article about it for more information.

The numeric type overview for MySQL states: BOOL, BOOLEAN: These types are synonyms for TINYINT(1). A value of zero is considered false. Nonzero values are considered true.

I would accept ldav1s' answer if I were you, but I just want to point out that 'else if' can be written in terms of 'else's and 'if's in any language:

if HAVE_CLIENT
  libtest_LIBS = $(top_builddir)/libclient.la
else
  if HAVE_SERVER
    libtest_LIBS = $(top_builddir)/libserver.la
  else
    libtest_LIBS = 
  endif
endif

(The indentation is for clarity. Don't indent the lines, they won't work.)

You have to provide 3 or 4 states in your btn_defaut.xml as a selector.

1. Pressed state
2. Default state
3. Focus state
4. Enabled state (Disable state with false indication; see comments)

You will provide effect and background for the states accordingly.

Here is a detailed discussion: Standard Android Button with a different color

This is easier and gives purpose to the never used unordered/ordered list tags.

In your CSS add:

    li{float: left;}  //Sets float left property globally for all li tags.

Then add in your HTML:

    <ul>
         <li>1</li>
         <li>2</li>
         <li>3</li>        
    </ul>

Now watch it all line up perfectly! No more arguing over tables vs divs!

content doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.

Another problem with your code is " inside a " block. You should mix ' and " (class='headingDetail').

If content did support HTML you could end up in an infinite loop where content is added inside content.

No, REST is the way HTTP should be used.

Today we only use a tiny bit of the HTTP protocol's methods – namely GET and POST. The REST way to do it is to use all of the protocol's methods.

For example, REST dictates the usage of DELETE to erase a document (be it a file, state, etc.) behind a URI, whereas, with HTTP, you would misuse a GET or POST query like ...product/?delete_id=22.

If your processes in same computer, you can simply use stdio.

Without Virtual Environments

pip <command> --user changes the scope of the current pip command to work on the current user account's local python package install location, rather than the system-wide package install location, which is the default.

• See User Installs in the PIP User Guide.

This only really matters on a multi-user machine. Anything installed to the system location will be visible to all users, so installing to the user location will keep that package installation separate from other users (they will not see it, and would have to install it themselves separately to use it). Because there can be version conflicts, installing a package with dependencies needed by other packages can cause problems, so it's best not to push all packages a given user uses to the system install location.

• If it is a single-user machine, there is little or no difference to installing to the --user location. It will be installed to a different folder, that may or may not need to be added to the path, depending on the package and how it's used (many packages install command-line tools that must be on the path to run from a shell).
• If it is a multi-user machine, --user is preferred to using root/sudo or requiring administrator installation and affecting the Python environment of every user, except in cases of general packages that the administrator wants to make available to all users by default.
  • Note: Per comments, on most Unix/Linux installs it has been pointed out that system installs should use the general package manager, such as apt, rather than pip.

With Virtual Environments

• See more about installing packages with virtual environments in the Python Packaging documentation.
• Read about how to create and use virtual environments, and the venv command in the Python VENV docs.

The --user option in an active venv/virtualenv environment will install to the local user python location (same as without a virtual environment).

Packages are installed to the virtual environment by default, but if you use --user it will force it to install outside the virtual environments, in the users python script directory (in Windows, this currently is c:\users\<username>\appdata\roaming\python\python37\scripts for me with Python 3.7).

However, you won't be able to access a system or user install from within virtual environment (even if you used --user while in a virtual environment).

If you install a virtual environment with the --system-site-packages argument, you will have access to the system script folder for python. I believe this included the user python script folder as well, but I'm unsure. However, there may be unintended consequences for this and it is not the intended way to use virtual environments.

Location of the Python System and Local User Install Folders

You can find the location of the user install folder for python with python -m site --user-base. I'm finding conflicting information in Q&A's, the documentation and actually using this command on my PC as to what the defaults are, but they are underneath the user home directory (~ shortcut in *nix, and c:\users\<username> typically for Windows).

Other Details

The --user option is not a valid for every command. For example pip uninstall will find and uninstall packages wherever they were installed (in the user folder, virtual environment folder, etc.) and the --user option is not valid.

Things installed with pip install --user will be installed in a local location that will only be seen by the current user account, and will not require root access (on *nix) or administrator access (on Windows).

The --user option modifies all pip commands that accept it to see/operate on the user install folder, so if you use pip list --user it will only show you packages installed with pip install --user.

To my knowledge there is no difference between NUMERIC and DECIMAL data types. They are synonymous to each other and either one can be used. DECIMAL and NUMERIC data types are numeric data types with fixed precision and scale.

Edit:

Speaking to a few collegues maybe its has something to do with DECIMAL being the ANSI SQL standard and NUMERIC being one Mircosoft prefers as its more commonly found in programming languages. ...Maybe ;)

    "success": true,
    "data": {

};

You can iterate over the index values if your dataframe has already been created.

df = df.groupby('l_customer_id_i').agg(lambda x: ','.join(x))
for name in df.index:
    print name
    print df.loc[name]

Fiddle

You can use clone, and then since each div has a class of car_well you can use insertAfter to insert after the last div.

$("#car2").clone().insertAfter("div.car_well:last");

You can use dijkstra's algorithm with negative edges not including negative cycle, but you must allow a vertex can be visited multiple times and that version will lose it's fast time complexity.

In that case practically I've seen it's better to use SPFA algorithm which have normal queue and can handle negative edges.

Android id overview

An Android id is an integer commonly used to identify views; this id can be assigned via XML (when possible) and via code (programmatically.) The id is most useful for getting references for XML-defined Views generated by an Inflater (such as by using setContentView.)

Assign id via XML

• Add an attribute of android:id="@+id/somename" to your view.
• When your application is built, the android:id will be assigned a unique int for use in code.
• Reference your android:id's int value in code using "R.id.somename" (effectively a constant.)
• this int can change from build to build so never copy an id from gen/package.name/R.java, just use "R.id.somename".
• (Also, an id assigned to a Preference in XML is not used when the Preference generates its View.)

Assign id via code (programmatically)

• Manually set ids using someView.setId(int);
• The int must be positive, but is otherwise arbitrary- it can be whatever you want (keep reading if this is frightful.)
• For example, if creating and numbering several views representing items, you could use their item number.

Uniqueness of ids

• XML-assigned ids will be unique.
• Code-assigned ids do not have to be unique
• Code-assigned ids can (theoretically) conflict with XML-assigned ids.
• These conflicting ids won't matter if queried correctly (keep reading).

When (and why) conflicting ids don't matter

• findViewById(int) will iterate depth-first recursively through the view hierarchy from the View you specify and return the first View it finds with a matching id.
• As long as there are no code-assigned ids assigned before an XML-defined id in the hierarchy, findViewById(R.id.somename) will always return the XML-defined View so id'd.

Dynamically Creating Views and Assigning IDs

• In layout XML, define an empty ViewGroup with id.
• Such as a LinearLayout with android:id="@+id/placeholder".
• Use code to populate the placeholder ViewGroup with Views.
• If you need or want, assign any ids that are convenient to each view.

• Query these child views using placeholder.findViewById(convenientInt);

• API 17 introduced View.generateViewId() which allows you to generate a unique ID.

If you choose to keep references to your views around, be sure to instantiate them with getApplicationContext() and be sure to set each reference to null in onDestroy. Apparently leaking the Activity (hanging onto it after is is destroyed) is wasteful.. :)

Reserve an XML android:id for use in code

API 17 introduced View.generateViewId() which generates a unique ID. (Thanks to take-chances-make-changes for pointing this out.)*

If your ViewGroup cannot be defined via XML (or you don't want it to be) you can reserve the id via XML to ensure it remains unique:

Here, values/ids.xml defines a custom id:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item name="reservedNamedId" type="id"/>
</resources>

Then once the ViewGroup or View has been created, you can attach the custom id

myViewGroup.setId(R.id.reservedNamedId);

Conflicting id example

For clarity by way of obfuscating example, lets examine what happens when there is an id conflict behind the scenes.

layout/mylayout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <LinearLayout
        android:id="@+id/placeholder"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >
</LinearLayout>

To simulate a conflict, lets say our latest build assigned R.id.placeholder(@+id/placeholder) an int value of 12..

Next, MyActivity.java defines some adds views programmatically (via code):

int placeholderId = R.id.placeholder; // placeholderId==12
// returns *placeholder* which has id==12:
ViewGroup placeholder = (ViewGroup)this.findViewById(placeholderId);
for (int i=0; i<20; i++){
    TextView tv = new TextView(this.getApplicationContext());
    // One new TextView will also be assigned an id==12:
    tv.setId(i);
    placeholder.addView(tv);
}

So placeholder and one of our new TextViews both have an id of 12! But this isn't really a problem if we query placeholder's child views:

// Will return a generated TextView:
 placeholder.findViewById(12);

// Whereas this will return the ViewGroup *placeholder*;
// as long as its R.id remains 12: 
Activity.this.findViewById(12);

*Not so bad

You could find the difference between dates in columns in a data frame by using the function difftime as follows:

df$diff_in_days<- difftime(df$datevar1 ,df$datevar2 , units = c("days"))

You can make use of the following code incase you want to check the types of primitive data types.

// Returns 0 if the object type is equal to double
strcmp([myNumber objCType], @encode(double)) 

With jQuery, I've done it this way:

function checkKey(e){
     switch (e.keyCode) {
        case 40:

Polymorphism:

It is the concept of object oriented programming.The ability of different objects to respond, each in its own way, to identical messages is called polymorphism.

Polymorphism results from the fact that every class lives in its own namespace. The names assigned within a class definition don’t conflict with names assigned anywhere outside it. This is true both of the instance variables in an object’s data structure and of the object’s methods:

• Just as the fields of a C structure are in a protected namespace, so are an object’s instance variables.

• Method names are also protected. Unlike the names of C functions, method names aren’t global symbols. The name of a method in one class can’t conflict with method names in other classes; two very different classes can implement identically named methods.

Method names are part of an object’s interface. When a message is sent requesting that an object do something, the message names the method the object should perform. Because different objects can have methods with the same name, the meaning of a message must be understood relative to the particular object that receives the message. The same message sent to two different objects can invoke two distinct methods.

The main benefit of polymorphism is that it simplifies the programming interface. It permits conventions to be established that can be reused in class after class. Instead of inventing a new name for each new function you add to a program, the same names can be reused. The programming interface can be described as a set of abstract behaviors, quite apart from the classes that implement them.

Examples:

Example-1: Here is a simple example written in Python 2.x.

class Animal:
    def __init__(self, name):    # Constructor of the class
        self.name = name
    def talk(self):              # Abstract method, defined by convention only
        raise NotImplementedError("Subclass must implement abstract method")

class Cat(Animal):
    def talk(self):
        return 'Meow!'

class Dog(Animal):
    def talk(self):
        return 'Woof! Woof!'

animals = [Cat('Missy'),
           Dog('Lassie')]

for animal in animals:
    print animal.name + ': ' + animal.talk()

Example-2: Polymorphism is implemented in Java using method overloading and method overriding concepts.

Let us Consider Car example for discussing the polymorphism. Take any brand like Ford, Honda, Toyota, BMW, Benz etc., Everything is of type Car.

But each have their own advanced features and more advanced technology involved in their move behavior.

Now let us create a basic type Car

Car.java

public class Car {

    int price;
    String name;
    String color;

    public void move(){
    System.out.println("Basic Car move");
    }

}

Let us implement the Ford Car example.

Ford extends the type Car to inherit all its members(properties and methods).

Ford.java

public class Ford extends Car{
  public void move(){
    System.out.println("Moving with V engine");
  }
}

The above Ford class extends the Car class and also implements the move() method. Even though the move method is already available to Ford through the Inheritance, Ford still has implemented the method in its own way. This is called method overriding.

Honda.java

public class Honda extends Car{
  public void move(){
    System.out.println("Move with i-VTEC engine");
  }
}

Just like Ford, Honda also extends the Car type and implemented the move method in its own way.

Method overriding is an important feature to enable the Polymorphism. Using Method overriding, the Sub types can change the way the methods work that are available through the inheritance.

PolymorphismExample.java

public class PolymorphismExample {
  public static void main(String[] args) {
    Car car = new Car();
    Car f = new Ford();
    Car h = new Honda();

    car.move();
    f.move();
    h.move();

  }
}

Polymorphism Example Output:

In the PolymorphismExample class main method, i have created three objects- Car, Ford and Honda. All the three objects are referred by the Car type.

Please note an important point here that A super class type can refer to a Sub class type of object but the vice-verse is not possible. The reason is that all the members of the super class are available to the subclass using inheritance and during the compile time, the compiler tries to evaluate if the reference type we are using has the method he is trying to access.

So, for the references car,f and h in the PolymorphismExample, the move method exists from Car type. So, the compiler passes the compilation process without any issues.

But when it comes to the run time execution, the virtual machine invokes the methods on the objects which are sub types. So, the method move() is invoked from their respective implementations.

So, all the objects are of type Car, but during the run time, the execution depends on the Object on which the invocation happens. This is called polymorphism.

String String_firstNumber = JOptionPane.showInputDialog("Input  Semisecond");
int Int_firstNumber = Integer.parseInt(firstNumber);

Now your Int_firstnumber contains integer value of String_fristNumber.

In some cases for some security reasons the unit would be marked as masked. This state is much stronger than being disabled in which you cannot even start the service manually.

to check this, run the following command:

    systemctl list-unit-files | grep mongod

if you find out something like this:

    mongod.service                         masked

then you can unmask the unit by:

    sudo systemctl unmask mongod

then you may want to start the service:

    sudo systemctl start mongod

and to enable auto-start during system boot:

    sudo systemctl enable mongod

However if mongodb did not start again or was not masked at all, you have the option to reinstall it this way:

    sudo apt-get --purge mongo*
    sudo apt-get install mongodb-org

I've never actually used this, but try view.getClass().getGenericSuperclass()

What I found out is that it's OK to put char* into a std::vector:

//  1 - A std::vector of char*, more preper way is to use a std::vector<std::vector<char>> or std::vector<std::string>
std::vector<char*> v(10, "hi!");    //  You cannot put standard library containers e.g. char[] into std::vector!
for (auto& i : v)
{
    //std::cout << i << std::endl;
    i = "New";
}
for (auto i : v)
{
    std::cout << i << std::endl;
}

Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885

This doesn't rely on serialization nor on content negotiation.

[HttpGet]
public ContentResult Index() {
    return new ContentResult {
        ContentType = "text/html",
        StatusCode = (int)HttpStatusCode.OK,
        Content = "<html><body>Hello World</body></html>"
    };
}

alter table table_name rename column oldColumn to newColumn;

Ok so the key for me was to use the .FlattenHierarchy BindingFlag. I don't really know why I just added it on a hunch and it started working. So the final solution that allows me to get Public Instance or Static Properties is:

obj.GetType.GetProperty(propName, Reflection.BindingFlags.Public _
  Or Reflection.BindingFlags.Static Or Reflection.BindingFlags.Instance Or _
  Reflection.BindingFlags.FlattenHierarchy)

Let me add some more use case of the square-bracket notation. If you want to access a property say x-proxy in a object, then - will be interpreted wrongly. Their are some other cases too like space, dot, etc., where dot operation will not help you. Also if u have the key in a variable then only way to access the value of the key in a object is by bracket notation. Hope you get some more context.

Creating new oauth credentials worked for me

I've seen all the answers here and the only thing missing is after going through these steps:

$ git add .
$ git commit -m "first heroku commit"

You should run the command below:

$ heroku git:remote -a <YourAppNameOnHeroku>

And lastly, run this:

$ git push -f heroku <NameOfBranch>:master

Notice I used <NameOfBranch> because if you're currently in a different branch to master it would still throw errors, so If you are working in master use master, else put the name of the branch there.

Create an AJAX postback method which writes a CSV file to your webserver and returns the url.. Set a hidden IFrame in the browser to the location of the CSV file on the server.

Your user will then be presented with the CSV download link.

This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.

However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.

In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.

Example Code

Here is a simple example based on a SAP system I have access to.

Public Sub SimpleSAPExport()
  Set SapGuiAuto  = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
  Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI 
  Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
  Set session = SAPCon.Children(0) 'Get the first session (window) on that connection

  'Start the transaction to view a table
  session.StartTransaction "SE16"

  'Select table T001
  session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
  session.findById("wnd[0]/tbar[1]/btn[7]").Press

  'Set our selection criteria
  session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
  session.findById("wnd[0]/tbar[1]/btn[8]").press

  'Click the export to file button
  session.findById("wnd[0]/tbar[1]/btn[45]").press

  'Choose the export format
  session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
  session.findById("wnd[1]/tbar[0]/btn[0]").press

  'Choose the export filename
  session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
  session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"

  'Export the file
  session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub

Script Recording

To help find the names of elements such aswnd[1]/tbar[0]/btn[0] you can use script recording. Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.

Within that the More button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.

Edit: Early and Late binding

The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI") defines the SapGuiAuto object.

If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx in the SAP GUI installation folder.

This can happen on foreachs when using:

foreach( $array as $key = $value )

instead of

foreach( $array as $key => $value )

Right-click the project node in the Projects window and choose Project Properties. then find run, there you can setup your main class,, **actually got it from netbeans default help

It's a descriptive part of the URL that is there to make it more human descriptive, but without necessarily being required by the web server - in What is a "slug" in Django? the slug is 'in-django-what-is-a-slug', but the slug is not used to determine the page served (on this site at least)

That usually means that your friend does not have the Microsoft redistributable for Visual C++. I am of course assuming you are using VC++ and not MingW or another compiler. Since your friend does not have VS installed as well there is no guarantee he has the redist installed.

I encounter same error, and incognito mode also has same issue. I resolve this issue by clear Chrome history.

A few principles:

1. you have a std::exception base class, you should have your exceptions derive from it. That way general exception handler still have some information.

2. Don't throw pointers but object, that way memory is handled for you.

Example:

struct MyException : public std::exception
{
   std::string s;
   MyException(std::string ss) : s(ss) {}
   ~MyException() throw () {} // Updated
   const char* what() const throw() { return s.c_str(); }
};

And then use it in your code:

void Foo::Bar(){
  if(!QueryPerformanceTimer(&m_baz)){
    throw MyException("it's the end of the world!");
  }
}

void Foo::Caller(){
  try{
    this->Bar();// should throw
  }catch(MyException& caught){
    std::cout<<"Got "<<caught.what()<<std::endl;
  }
}

//Get the size in bytes
function calculateFileSize($size)
{
   $sizes = ['B', 'KB', 'MB', 'GB'];
   $count=0;
   if ($size < 1024) {
    return $size . " " . $sizes[$count];
    } else{
     while ($size>1024){
        $size=round($size/1024,2);
        $count++;
    }
     return $size . " " . $sizes[$count];
   }
}

I had a big dataset and .loc[] was taking too long so I found a vectorized way to do it. Recall that you can set a column to a logical operator, so this works:

file['Flag'] = (file['Claim_Amount'] > 0)

This gives a Boolean, which I wanted, but you can multiply it by, say, 1 to make an Integer.

It has a tricky situation: If you submit a post form, then Chrome will open a new tab to send the request. It's right until now, but if it triggers an event to download file(s), this tab will close immediately so that you cannot capture this request in the Dev Tool.

Solution: Before submitting the post form, you need to cut off your network, which makes the request cannot send successfully so that the tab will not be closed. And then you can capture the request message in the Chrome Devtool(Refreshing the new tab if necessary)

In my case, Python was unable to find it because I'd put the code inside a module with hyphens, e.g. my-module. When I changed it to my_module it worked.

Three Answers :

Simple :

    <xsl:attribute name="src">
        <xsl:value-of select="//your/xquery/path"/>
        <xsl:value-of select="'vmLogo.gif'"/>
    </xsl:attribute>
</img>

Using 'concat' :

<img>
    <xsl:attribute name="src">
        <xsl:value-of select="concat(//your/xquery/path,'vmLogo.gif')"/>                    
    </xsl:attribute>
</img>

Attribute shortcut as suggested by @TimC

<img src="{concat(//your/xquery/path,'vmLogo.gif')}" />

you can use equals() method to statisfy your demands. == in java programming language has a different meaning!

A little improved and wrapped into a manager solution.

Things to keep in mind. FragmentManager is not a singleton, it manages only Fragments within Activity, so in every activity it will be new. Also, this solution so far doesn't take ViewPager into account that calls setUserVisibleHint() method helping to control visiblity of Fragments.

Feel free to use following classes when dealing with this issue (uses Dagger2 injection). Call in Activity:

//inject FragmentBackstackStateManager instance to myFragmentBackstackStateManager
FragmentManager fragmentManager = getSupportFragmentManager(); 
myFragmentBackstackStateManager.apply(fragmentManager);

FragmentBackstackStateManager.java:

@Singleton
public class FragmentBackstackStateManager {

    private FragmentManager fragmentManager;

    @Inject
    public FragmentBackstackStateManager() {
    }

    private BackstackCallback backstackCallbackImpl = new BackstackCallback() {
        @Override
        public void onFragmentPushed(Fragment parentFragment) {
            parentFragment.onPause();
        }

        @Override
        public void onFragmentPopped(Fragment parentFragment) {
            parentFragment.onResume();
        }
    };

    public FragmentBackstackChangeListenerImpl getListener() {
        return new FragmentBackstackChangeListenerImpl(fragmentManager, backstackCallbackImpl);
    }

    public void apply(FragmentManager fragmentManager) {
        this.fragmentManager = fragmentManager;
        fragmentManager.addOnBackStackChangedListener(getListener());
    }
}

FragmentBackstackChangeListenerImpl.java:

public class FragmentBackstackChangeListenerImpl implements FragmentManager.OnBackStackChangedListener {

    private int lastBackStackEntryCount = 0;
    private final FragmentManager fragmentManager;
    private final BackstackCallback backstackChangeListener;

    public FragmentBackstackChangeListenerImpl(FragmentManager fragmentManager, BackstackCallback backstackChangeListener) {
        this.fragmentManager = fragmentManager;
        this.backstackChangeListener = backstackChangeListener;
        lastBackStackEntryCount = fragmentManager.getBackStackEntryCount();
    }

    private boolean wasPushed(int backStackEntryCount) {
        return lastBackStackEntryCount < backStackEntryCount;
    }

    private boolean wasPopped(int backStackEntryCount) {
        return lastBackStackEntryCount > backStackEntryCount;
    }

    private boolean haveFragments() {
        List<Fragment> fragmentList = fragmentManager.getFragments();
        return fragmentList != null && !fragmentList.isEmpty();
    }


    /**
     * If we push a fragment to backstack then parent would be the one before => size - 2
     * If we pop a fragment from backstack logically it should be the last fragment in the list, but in Android popping a fragment just makes list entry null keeping list size intact, thus it's also size - 2
     *
     * @return fragment that is parent to the one that is pushed to or popped from back stack
     */
    private Fragment getParentFragment() {
        List<Fragment> fragmentList = fragmentManager.getFragments();
        return fragmentList.get(Math.max(0, fragmentList.size() - 2));
    }

    @Override
    public void onBackStackChanged() {
        int currentBackStackEntryCount = fragmentManager.getBackStackEntryCount();
        if (haveFragments()) {
            Fragment parentFragment = getParentFragment();

            //will be null if was just popped and was last in the stack
            if (parentFragment != null) {
                if (wasPushed(currentBackStackEntryCount)) {
                    backstackChangeListener.onFragmentPushed(parentFragment);
                } else if (wasPopped(currentBackStackEntryCount)) {
                    backstackChangeListener.onFragmentPopped(parentFragment);
                }
            }
        }

        lastBackStackEntryCount = currentBackStackEntryCount;
    }
}

BackstackCallback.java:

public interface BackstackCallback {
    void onFragmentPushed(Fragment parentFragment);

    void onFragmentPopped(Fragment parentFragment);
}

Add these two properties to your parent layout (ex: Linear Layout, Relative Layout)

android:focusable="true"
android:focusableInTouchMode="true" 

It will do the trick :)

The best solution is using DATE() function and extracting yy, mm, and dd from the string with RIGHT(), MID() and LEFT() functions, the final will be some DATE(LEFT(),MID(),RIGHT()), details here

So, for future reference for anybody who doesn't want to spend two days searching the internet to figure this out, when you encode byte arrays into QR Codes, you have to use the ISO-8859-1character set, not UTF-8.

Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.

This command would be:

brew install python

Use Homebrew to install packages that you would otherwise use apt-get for.

The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:

Type the following in your Mac OS X terminal:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After that, usage of Homebrew is brew install <package>.

One of the prerequisites for Homebrew are the XCode command line tools.

1. Install XCode from the App Store.
2. Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.

Background

A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.

Alpine based systems use apk.

Warning

As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:

Setting an environment variable:

1. Open your favorite environment variable editor.
2. Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
3. Close the file, and either restart the terminal or source ~/.bash_profile.

Running the following command:

brew analytics off

the analytics status can then be checked with the command:

brew analytics

  $("#customFile").change(function() { 
    var fileName = $("#customFile").val();  

    if(fileName) { // returns true if the string is not empty   
        $('.picture-selected').addClass('disable-inputs'); 
        $('#btn').removeClass('disabled');   
    } else { // no file was selected 
      $('.picture-selected').removeClass('disable-inputs'); 
      $('#btn').addClass('disabled');
    }  
  });

you cannot set target attribute to div, becacuse div does not know how to handle http requests. instead of you set target attribute for link tag.

$(this).find("a").target = "_blank";
window.location= $(this).find("a").attr("href")

Since you're using Spring Boot, I assume you'd prefer to rely on Spring's auto configuration where possible. To add additional custom configuration like your interceptors, just provide a configuration or bean of WebMvcConfigurerAdapter.

Here's an example of a config class:

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

  @Autowired 
  HandlerInterceptor yourInjectedInterceptor;

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(...)
    ...
    registry.addInterceptor(getYourInterceptor()); 
    registry.addInterceptor(yourInjectedInterceptor);
    // next two should be avoid -- tightly coupled and not very testable
    registry.addInterceptor(new YourInterceptor());
    registry.addInterceptor(new HandlerInterceptor() {
        ...
    });
  }
}

NOTE do not annotate this with @EnableWebMvc, if you want to keep Spring Boots auto configuration for mvc.

If you are using CentOS or another Linux flavour then just do Ctrl+R at the prompt and type git.

If you keep hitting Ctrl+R this will do a reverse search through your history for commands that start with git

Because of the Google's banning problem I prefer to use Microsoft's cdn http://www.asp.net/ajaxlibrary/cdn.ashx

I would simply use:

stream.count()>0

One solution where we need not know the width/height of the dialog and then assume the margins.

Html:

<div id="dialog-contain">  <-- This div because I assume you might have a display that is not a flex. '
    <div id="block">
        <div id="centered">
            stuffs
        </div>
    </div>
</div>

Css:

#dialog-contain { // full page container.
    position: absolute;
    height: 100%;
    width: 100%;
    top: 0;
    left: 0;
    ...
}

#block {  // another container simply with display:flex.
    display: flex;
    height: 100%;
    width: 100%;
    justify-content: center;
}

#centered {   // another container that is always centered.
    align-self: center;
}

So at the most basic level a HANDLE of any sort is a pointer to a pointer or

#define HANDLE void **

Now as to why you would want to use it

Lets take a setup:

class Object{
   int Value;
}

class LargeObj{

   char * val;
   LargeObj()
   {
      val = malloc(2048 * 1000);
   }

}

void foo(Object bar){
    LargeObj lo = new LargeObj();
    bar.Value++;
}

void main()
{
   Object obj = new Object();
   obj.val = 1;
   foo(obj);
   printf("%d", obj.val);
}

So because obj was passed by value (make a copy and give that to the function) to foo, the printf will print the original value of 1.

Now if we update foo to:

void foo(Object * bar)
{
    LargeObj lo = new LargeObj();
    bar->val++;
}

There is a chance that the printf will print the updated value of 2. But there is also the possibility that foo will cause some form of memory corruption or exception.

The reason is this while you are now using a pointer to pass obj to the function you are also allocating 2 Megs of memory, this could cause the OS to move the memory around updating the location of obj. Since you have passed the pointer by value, if obj gets moved then the OS updates the pointer but not the copy in the function and potentially causing problems.

A final update to foo of:

void foo(Object **bar){
    LargeObj lo = LargeObj();
    Object * b = &bar;
    b->val++;
}

This will always print the updated value.

See, when the compiler allocates memory for pointers it marks them as immovable, so any re-shuffling of memory caused by the large object being allocated the value passed to the function will point to the correct address to find out the final location in memory to update.

Any particular types of HANDLEs (hWnd, FILE, etc) are domain specific and point to a certain type of structure to protect against memory corruption.

Edit: This code will wait until all content (images and scripts) are fully loaded and rendered in the browser.

I've had this problem where $(window).on('load',function(){ ... }) would fire too quick for my code since the Javascript I used was for formatting purposes and hiding elements. The elements where hidden too soon and where left with a height of 0.

I now use $(window).on('pageshow',function(){ //code here }); and it fires at the time I need.

I am not sure you can 100% bullet proof the script from not hanging or crashing, as there are things outside your control (what if the server loses power mid-upload?) - but this should provide a solid foundation for getting you started:

# create the FtpWebRequest and configure it
$ftp = [System.Net.FtpWebRequest]::Create("ftp://localhost/me.png")
$ftp = [System.Net.FtpWebRequest]$ftp
$ftp.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$ftp.Credentials = new-object System.Net.NetworkCredential("anonymous","anonymous@localhost")
$ftp.UseBinary = $true
$ftp.UsePassive = $true
# read in the file to upload as a byte array
$content = [System.IO.File]::ReadAllBytes("C:\me.png")
$ftp.ContentLength = $content.Length
# get the request stream, and write the bytes into it
$rs = $ftp.GetRequestStream()
$rs.Write($content, 0, $content.Length)
# be sure to clean up after ourselves
$rs.Close()
$rs.Dispose()

In jQuery, a new element can be created by passing a HTML string to the constructor, as shown below:

var img = $('<img id="dynamic">'); //Equivalent: $(document.createElement('img'))
img.attr('src', responseObject.imgurl);
img.appendTo('#imagediv');

ZedGraph is a good choice.

You can do both in one query using the OVER clause on another COUNT

select
    count(*) RecordsPerGroup,
    COUNT(*) OVER () AS TotalRecords
from temptable
group by column_1, column_2, column_3, column_4

Another possible cause for Googlers: Using additional units in a size like so:

$('#file_upload').uploadify({
    'uploader'  : '/uploadify/uploadify.swf',
    'script'    : '/uploadify/uploadify.php',
    'cancelImg' : '/uploadify/cancel.png',
    'folder'    : '/uploads',
    'queueID'        : 'custom-queue',
    'buttonImg': 'img/select-images.png',
    'width': '351px'
});

Setting '351px' there gave me the error. Removing 'px' banished the error.

Below Python packages are to be downloaded and installed to their default locations.

1.1. Python-2.7.x.

1.2. Numpy.

1.3. Matplotlib (Matplotlib is optional, but recommended since we use it a lot in our tutorials).

Install all packages into their default locations. Python will be installed to C:/Python27/.

After installation, open Python IDLE. Enter import numpy and make sure Numpy is working fine.

Download latest OpenCV release from sourceforge site and double-click to extract it.

Goto opencv/build/python/2.7 folder.

Copy cv2.pyd to C:/Python27/lib/site-packeges.

Open Python IDLE and type following codes in Python terminal.

import cv2 print cv2.version If the results are printed out without any errors, congratulations !!! You have installed OpenCV-Python successfully.

https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_setup/py_setup_in_windows/py_setup_in_windows.html

Please write the following code in your console:

var isEven = function(deep) {

  if (deep % 2 === 0) {
        return true;  
    }
    else {
        return false;    
    }
};
isEven(44);

Please Note: It will return true, if the entered number is even otherwise false.

Try any of these

valof = moment().valueOf();            // xxxxxxxxxxxxx
getTime = moment().toDate().getTime(); // xxxxxxxxxxxxx
unixTime =  moment().unix();           // xxxxxxxxxx
formatTimex =  moment().format('x');   // xxxxxxxxxx
unixFormatX = moment().format('X');    // xxxxxxxxxx

We can use relative path instead of absolute path:

$assetPath: '~src/assets/images/';
$logo-img: '#{$assetPath}logo.png';
@mixin logo {
  background-image: url(#{$logo-img});
}

.logo {
    max-width: 65px;
    @include logo;
 }

1. Eclipse -> Top menu -> Run -> Run Configurations
2. Delete all the occurrences of your test. Your test may appear as YourTest.Method_1(). Delete that as well.
3. Re-run. Let Eclipse build a fresh configuration.

Addendum: Locally I have created a "User Library" and added to my projects which has

hamcrest-core-1.3.jar

junit-4.12.jar

I found a good Blog post about the behaviour of Hibernate in this kind of object mappings: http://blog.eyallupu.com/2010/06/hibernate-exception-simultaneously.html

I like the Infragistics controls. The WebDropDown has what you need. The only drawback is they can be a bit spendy.

Provide a format string:

If you are on .NET 4.0 use a Tuple:

lookup = new Dictionary<Tuple<TypeA, TypeB, TypeC>, string>();

If not you can define a Tuple and use that as the key. The Tuple needs to override GetHashCode, Equals and IEquatable:

struct Tuple<T, U, W> : IEquatable<Tuple<T,U,W>>
{
    readonly T first;
    readonly U second;
    readonly W third;

    public Tuple(T first, U second, W third)
    {
        this.first = first;
        this.second = second;
        this.third = third;
    }

    public T First { get { return first; } }
    public U Second { get { return second; } }
    public W Third { get { return third; } }

    public override int GetHashCode()
    {
        return first.GetHashCode() ^ second.GetHashCode() ^ third.GetHashCode();
    }

    public override bool Equals(object obj)
    {
        if (obj == null || GetType() != obj.GetType())
        {
            return false;
        }
        return Equals((Tuple<T, U, W>)obj);
    }

    public bool Equals(Tuple<T, U, W> other)
    {
        return other.first.Equals(first) && other.second.Equals(second) && other.third.Equals(third);
    }
}

You can also use:

driver.switch_to.frame(0)

(0) being the first iframe on the html.

to switch back to the default content:

driver.switch_to.default_content()

To change just the colour of the player, simply address the audio tag in your css file, for instance on one of my sites the player became invisible (white on white) so I added:

audio {
    background-color: #95B9C7;
}

This changed the player to light blue.

If you're using Visual Studio you could also do "#pragma once" at the top of the headerfile to achieve the same thing as the "#ifndef ..."-wrapping. Some other compilers probably support it as well .. .. However, don't do this :D Stick with the #ifndef-wrapping to achieve cross-compiler compatibility. I just wanted to let you know that you could also do #pragma once, since you'll probably meet this statement quite a bit when reading other peoples code.

Good luck with it

I tried all the above and it did not work.

I found that in spite of uninstalling the app a new version of the app still gives the same error.

This is what solved it: go to Settings -> General -> application Manager -> choose your app -> click on the three dots on the top -> uninstall for all users

Once you do this, now it is actually uninstalled and will now allow your new version to install.

Hope this helps.

onblur fires when a field loses focus, while onchange fires when that field's value changes. These events will not always occur in the same order, however.

In Firefox, tabbing out of a changed field will fire onchange then onblur, and it will normally do the same in IE. However, if you press the enter key instead of tab, in Firefox it will fire onblur then onchange, while IE will usually fire in the original order. However, I've seen cases where IE will also fire blur first, so be careful. You can't assume that either the onblur or the onchange will happen before the other one.

That's all unnecessary logic in partials, reduce it to something like this and process your data in controller/service where it should be

<div ng-repeat="details in myDataSet">

    <p>{{ details.Name }}</p>
    <p>{{ details.DOB  }}</p>
    <p>{{details.Payment[0].StatusName}}</p>
    <p>{{ details.Gender}}</p>

</div>

JS:

angular.forEach(myDataSet.Payment, function (payment) {
  if(payment.Status === 0){
    payment.StatusName = 'No Payment';
  } else if(payment.Status === 1 || payment.Status === 2){
    payment.StatusName = 'Late';
  } else if(payment.Status === 3 || payment.Status === 4 || payment.Status === 5){
    payment.StatusName = 'Some payment made';
  } else if(payment.Status === 6){
    payment.StatusName = 'Late and further taken out';
  }else{
    payment.StatusName = 'Error';
  }
})

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

Adding to the answer of Fatal Error, There is one more way to pass the variables to another shell script.

The above suggested solution have some drawbacks:

1. using Export : It will cause the variable to be present out of their scope which is not a good design practice.
2. using Source : It may cause name collisions or accidental overwriting of a predefined variable in some other shell script file which have sourced another file.

There is another simple solution avaiable for us to use. Considering the example posted by you,

test.sh

#!/bin/bash

TESTVARIABLE=hellohelloheloo
./test2.sh "$TESTVARIABLE"

test2.sh

#!/bin/bash

echo $1

output

hellohelloheloo

Also it is important to note that "" are necessary if we pass multiword strings. Taking one more example

master.sh

#!/bin/bash
echo in master.sh
var1="hello world"
sh slave1.sh $var1
sh slave2.sh "$var1"
echo back to master

slave1.sh

#!/bin/bash
echo in slave1.sh
echo value :$1

slave2.sh

#!/bin/bash
echo in slave2.sh
echo value : $1

output

in master.sh
in slave1.sh
value :"hello
in slave2.sh
value :"hello world"

It happens because of the reasons aptly described in this link

Swift 3.0

i had the same problem, i found on the documentation Apple this solution.

let numbers = [1, 2, 3, 4]
let addTwo: (Int, Int) -> Int = { x, y in x + y }
let numberSum = numbers.reduce(0, addTwo)
// 'numberSum' == 10

But, in my case i had a list of object, then i needed transform my value of my list:

let numberSum = self.list.map({$0.number_here}).reduce(0, { x, y in x + y })

this work for me.

And I have to add one more thing: This bit of shorthand is an abomination. It misuses an accidental interpreter optimization (not bothering with the second operation if the first is truthy) to control an assignment. That use has nothing to do with the purpose of the operator. I do not believe it should ever be used.

I prefer the ternary operator for initialization, eg,

var title = title?title:'Error';

This uses a one-line conditional operation for its correct purpose. It still plays unsightly games with truthiness but, that's Javascript for you.

Apply the below line of code :

<TextInput
  style={{ height: 40, width: "95%", borderColor: 'gray', borderWidth: 2, borderRadius: 20,  marginBottom: 20, fontSize: 18, backgroundColor: '#68a0cf' }}
  // Adding hint in TextInput using Placeholder option.
  placeholder=" Enter Your First Name"
  // Making the Under line Transparent.
  underlineColorAndroid="transparent"
/>

I came across this today and fixed the problem by removing the IISUrl from the Project file:

1. Right click project
2. Click Edit

3. Delete the following line:

    <IISUrl>http://localhost:xxxxx </IISUrl>
   

4. Reload project

5. Now add a new IIS virtual directory by right clicking Project > Properties > Web and selecting Use Local IIS Web Server (Uncheck Use IIS Express) and clicking the Create Virtual Directory button.

If you are using an MVC framework with routes and actions:

$(document).ready(function () {
    $('a[href="' + this.location.pathname + '"]').parent().addClass('active');
});

As illustrated in this answer by Christian Landgren: https://stackoverflow.com/a/13375529/101662

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

None of that stuff worked. Here's a much simpler way .. the label str is the pointer to what IS an array...

String str = String(yourNumber, DEC); // Obviously .. get your int or byte into the string

str = str + '\r' + '\n'; // Add the required carriage return, optional line feed

byte str_len = str.length();

// Get the length of the whole lot .. C will kindly
// place a null at the end of the string which makes
// it by default an array[].
// The [0] element is the highest digit... so we
// have a separate place counter for the array...

byte arrayPointer = 0;

while (str_len)
{
    // I was outputting the digits to the TX buffer

    if ((UCSR0A & (1<<UDRE0))) // Is the TX buffer empty?
    {
        UDR0 = str[arrayPointer];
        --str_len;
        ++arrayPointer;
    }
}

We use {SmartAssembly} for .NET protection of an enterprise level distributed application, and it has worked great for us.

I didn't see the link here, but there's a beta .NET Connector for MySql. Click "Development Releases" to download 6.3.2 beta, which has EF4/VS2010 integration:

http://dev.mysql.com/downloads/connector/net/5.0.html#downloads

You can access the timezone by the following script:

SELECT * FROM pg_timezone_names WHERE name = current_setting('TIMEZONE');

• current_setting('TIMEZONE') will give you Continent / Capital information of settings
• pg_timezone_names The view pg_timezone_names provides a list of time zone names that are recognized by SET TIMEZONE, along with their associated abbreviations, UTC offsets, and daylight-savings status.
• name column in a view (pg_timezone_names) is time zone name.

output will be :

name- Europe/Berlin, 
abbrev - CET, 
utc_offset- 01:00:00, 
is_dst- false

Perhaps a better way is using the php function in_array() like this:

$style='V';//can be 'V'ertical or 'H'orizontal
$lineBreak=($style=='V')?'<br>':'';
$name='colors';//the name of your options
$Legent="Select your $name";//dress it up in a nice fieldset with a ledgent
$options=array('red','green','blue','orange','yellow','white','black');
$boxes='';//innitiate the list of tickboxes to be generated
if(isset($_REQUEST["$name"])){ 
//we shall use $_REQUEST but $_POST would be better
   $Checked=$_REQUEST["$name"];
}else{
   $Checked=array();
}
foreach($options as $option){
$checkmark=(in_array($option,$Checked))?'checked':'';
$nameAsArray=$name.'[]';//we would like the returned data to be in an array so we end with []
$boxes.=($style=='V')?"<span class='label2' align='right'><b>$option : </b></span>":"<b>$option </b>";
$boxes.="<input style='width:2em;' type='checkbox' name='$nameAsArray' id='$option' value='$option' $checkmark >$lineBreak";
}

echo<<<EOF
<html>
<head></head>
<body>
<form name="Update" method="GET" action="{$_SERVER['PHP_SELF']}">\n
<fieldset id="tickboxes" style="width:25em;">
<legend>{$Legent}</legend>
{$boxes}
</fieldset>
<button type="submit" >Submit Form</button>
</form>
<body>
</html>
EOF
;

To start with we have created a variable $style to set if we want the options in a horizontal or vertical way. This will infrequence how we display our checkboxes. Next we set the $name for our options, this is needed as a name of the array where we want to keep our options. I have created a loop here to construct each option as given in the array $options, then we check each item if it should be checked in our returned form. I believe this should simplify the way we can reproduce a form with checkboxes.

The CSS: div{ overflow-y:scroll; overflow-x:scroll; width:20px; height:30px; } table{ width:50px; height:50px; }

You can make the table and the DIV around the table be any size you want, just make sure that the DIV is smaller than the table. You MUST contain the table inside of the DIV.

Updating .npmrc and the registry to https:// worked for me

registry=https://registry.npmjs.org/

Just make the property !important in your css file so that background color doesnot change on mouse over.This worked for me.

Example:

.fbColor {
    background-color: #3b5998 !important;
    color: white;
}

In most languages i am aware of, the actual regex for validating should be ^[0-9]{1,10}$; otherwise the matcher will also return positive matches if the to be validated number is part of a longer string.

You can install the following two NuGet packages:

using Microsoft.Extensions.Configuration; 
using Microsoft.Extensions.Configuration.Binder;

And then you'll have the possibility to use the following extension method:

var myArray = _config.GetSection("MyArray").Get<string[]>();

If you have multiple Action within same file then pass the same argument e.g. Id to all Action. This is because action only can identify Id, So instead of giving any name to argument only declare Id like this.

[httpget]
[ActionName("firstAction")] firstAction(string Id)
{.....
.....
}
[httpget]
[ActionName("secondAction")] secondAction(Int Id)
{.....
.....
}
//Now go to webroute.config file under App-start folder and add following
routes.MapHttpRoute(
name: "firstAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);

routes.MapHttpRoute(
name: "secondAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);

Say you have a superclass Fruit and the subclass Banana and you have a method addBananaToBasket()

The method will not accept grapes for example so you want to make sure that you're adding a banana to the basket.

So:

Fruit myFruit = new Banana();
((Banana)myFruit).addBananaToBasket(); ? This is called casting

If you want to replace those ugly ==> <== with something else

tail -n +1 *.txt | sed -e 's/==>/\n###/g' -e 's/<==/###/g' >> "files.txt"

explanation:

tail -n +1 *.txt - output all files in folder with header

sed -e 's/==>/\n###/g' -e 's/<==/###/g' - replace ==> with new line + ### and <== with just ###

>> "files.txt" - output all to a file

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

I just looked at the link @tracevipin added (http://www.w3.org/2010/05/video/mediaevents.html), and I saw a property named "paused".

I have ust tested it and it works just fine.

To complete André's answer, an ant solution could be like the one described in Emacs, JDEE, Ant, and the Eclipse Java Compiler, as in:

      <javac
          srcdir="${src}"
          destdir="${build.dir}/classes"> 
        <compilerarg 
           compiler="org.eclipse.jdt.core.JDTCompilerAdapter" 
           line="-warn:+unused -Xemacs"/>
        <classpath refid="compile.classpath" />
      </javac>

The compilerarg element also allows you to pass in additional command line args to the eclipse compiler.

You can find a full ant script example here which would be invoked in a command line with:

java -cp C:/eclipse-SDK-3.4-win32/eclipse/plugins/org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar org.eclipse.core.launcher.Main -data "C:\Documents and Settings\Administrator\workspace" -application org.eclipse.ant.core.antRunner -buildfile build.xml -verbose

BUT all that involves ant, which is not what Keith is after.

For a batch compilation, please refer to Compiling Java code, especially the section "Using the batch compiler"

The batch compiler class is located in the JDT Core plug-in. The name of the class is org.eclipse.jdt.compiler.batch.BatchCompiler. It is packaged into plugins/org.eclipse.jdt.core_3.4.0..jar. Since 3.2, it is also available as a separate download. The name of the file is ecj.jar.
Since 3.3, this jar also contains the support for jsr199 (Compiler API) and the support for jsr269 (Annotation processing). In order to use the annotations processing support, a 1.6 VM is required.

Running the batch compiler From the command line would give

java -jar org.eclipse.jdt.core_3.4.0<qualifier>.jar -classpath rt.jar A.java

or:

java -jar ecj.jar -classpath rt.jar A.java

All java compilation options are detailed in that section as well.

The difference with the Visual Studio command line compilation feature is that Eclipse does not seem to directly read its .project and .classpath in a command-line argument. You have to report all information contained in the .project and .classpath in various command-line options in order to achieve the very same compilation result.

So, then short answer is: "yes, Eclipse kind of does." ;)

Your question shows you have succumbed to some of the common misconceptions surrounding table variables and temporary tables.

I have written quite an extensive answer on the DBA site looking at the differences between the two object types. This also addresses your question about disk vs memory (I didn't see any significant difference in behaviour between the two).

Regarding the question in the title though as to when to use a table variable vs a local temporary table you don't always have a choice. In functions, for example, it is only possible to use a table variable and if you need to write to the table in a child scope then only a #temp table will do (table-valued parameters allow readonly access).

Where you do have a choice some suggestions are below (though the most reliable method is to simply test both with your specific workload).

1. If you need an index that cannot be created on a table variable then you will of course need a #temporary table. The details of this are version dependant however. For SQL Server 2012 and below the only indexes that could be created on table variables were those implicitly created through a UNIQUE or PRIMARY KEY constraint. SQL Server 2014 introduced inline index syntax for a subset of the options available in CREATE INDEX. This has been extended since to allow filtered index conditions. Indexes with INCLUDE-d columns or columnstore indexes are still not possible to create on table variables however.

2. If you will be repeatedly adding and deleting large numbers of rows from the table then use a #temporary table. That supports TRUNCATE (which is more efficient than DELETE for large tables) and additionally subsequent inserts following a TRUNCATE can have better performance than those following a DELETE as illustrated here.

3. If you will be deleting or updating a large number of rows then the temp table may well perform much better than a table variable - if it is able to use rowset sharing (see "Effects of rowset sharing" below for an example).
4. If the optimal plan using the table will vary dependent on data then use a #temporary table. That supports creation of statistics which allows the plan to be dynamically recompiled according to the data (though for cached temporary tables in stored procedures the recompilation behaviour needs to be understood separately).
5. If the optimal plan for the query using the table is unlikely to ever change then you may consider a table variable to skip the overhead of statistics creation and recompiles (would possibly require hints to fix the plan you want).
6. If the source for the data inserted to the table is from a potentially expensive SELECT statement then consider that using a table variable will block the possibility of this using a parallel plan.
7. If you need the data in the table to survive a rollback of an outer user transaction then use a table variable. A possible use case for this might be logging the progress of different steps in a long SQL batch.
8. When using a #temp table within a user transaction locks can be held longer than for table variables (potentially until the end of transaction vs end of statement dependent on the type of lock and isolation level) and also it can prevent truncation of the tempdb transaction log until the user transaction ends. So this might favour the use of table variables.
9. Within stored routines, both table variables and temporary tables can be cached. The metadata maintenance for cached table variables is less than that for #temporary tables. Bob Ward points out in his tempdb presentation that this can cause additional contention on system tables under conditions of high concurrency. Additionally, when dealing with small quantities of data this can make a measurable difference to performance.

Effects of rowset sharing

DECLARE @T TABLE(id INT PRIMARY KEY, Flag BIT);

CREATE TABLE #T (id INT PRIMARY KEY, Flag BIT);

INSERT INTO @T 
output inserted.* into #T
SELECT TOP 1000000 ROW_NUMBER() OVER (ORDER BY @@SPID), 0
FROM master..spt_values v1, master..spt_values v2

SET STATISTICS TIME ON

/*CPU time = 7016 ms,  elapsed time = 7860 ms.*/
UPDATE @T SET Flag=1;

/*CPU time = 6234 ms,  elapsed time = 7236 ms.*/
DELETE FROM @T

/* CPU time = 828 ms,  elapsed time = 1120 ms.*/
UPDATE #T SET Flag=1;

/*CPU time = 672 ms,  elapsed time = 980 ms.*/
DELETE FROM #T

DROP TABLE #T

This is much simple and easy way.

import pandas
df = pandas.read_excel(open('your_xls_xlsx_filename','rb'), sheetname='Sheet 1')
# or using sheet index starting 0
df = pandas.read_excel(open('your_xls_xlsx_filename','rb'), sheetname=2)

FutureWarning: The sheetname keyword is deprecated for newer Pandas versions, use sheet_name instead.

The difference lies in the fact that ./gradlew indicates you are using a gradle wrapper. The wrapper is generally part of a project and it facilitates installation of gradle. If you were using gradle without the wrapper you would have to manually install it - for example, on a mac brew install gradle and then invoke gradle using the gradle command. In both cases you are using gradle, but the former is more convenient and ensures version consistency across different machines.

Each Wrapper is tied to a specific version of Gradle, so when you first run one of the commands above for a given Gradle version, it will download the corresponding Gradle distribution and use it to execute the build.

Not only does this mean that you don’t have to manually install Gradle yourself, but you are also sure to use the version of Gradle that the build is designed for. This makes your historical builds more reliable

Read more here - https://docs.gradle.org/current/userguide/gradle_wrapper.html

Also, Udacity has a neat, high level video explaining the concept of the gradle wrapper - https://www.youtube.com/watch?v=1aA949H-shk

Due to PermGen removal some options were removed (like -XX:MaxPermSize), but options -Xms and -Xmx work in Java 8. It's possible that under Java 8 your application simply needs somewhat more memory. Try to increase -Xmx value. Alternatively you can try to switch to G1 garbage collector using -XX:+UseG1GC.

Note that if you use any option which was removed in Java 8, you will see a warning upon application start:

$ java -XX:MaxPermSize=128M -version
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128M; support was removed in 8.0
java version "1.8.0_25"

In Select2 V.4

use $('selector').select2().val(value_to_select).trigger('change');

I think it should work

I have same issue with IIS, i uninstalled IIS. Type in run services.msc, I see "wampapache64" service was not running, when I start it using right click it give me error.

I just used these steps.

1. Click on WAMP icon select Apache -> Service -> Remove Service

2. Click on Wamp icon select Apache -> Service -> Install Service

Got green Wamp icon :(

Yes, the SSL connection is between the TCP layer and the HTTP layer. The client and server first establish a secure encrypted TCP connection (via the SSL/TLS protocol) and then the client will send the HTTP request (GET, POST, DELETE...) over that encrypted TCP connection.

I'd bet that Programmer's Notepad would give you something like that...

Use this code, it is working perfectly. I have create a sql function that accept two parameters, the first param is the long string that we want to search into it,and it can accept string length up to 1500 character(of course you can extend it or even change it to text datatype). And the second parameter is the substring that we want to calculate the number of its occurance(its length is up to 200 character, of course you can change it to what your need). and the output is an integer, represent the number of frequency.....enjoy it.

CREATE FUNCTION [dbo].[GetSubstringCount]
(
  @InputString nvarchar(1500),
  @SubString NVARCHAR(200)
)
RETURNS int
AS
BEGIN 
        declare @K int , @StrLen int , @Count int , @SubStrLen int 
        set @SubStrLen = (select len(@SubString))
        set @Count = 0
        Set @k = 1
        set @StrLen =(select len(@InputString))
    While @K <= @StrLen
        Begin
            if ((select substring(@InputString, @K, @SubStrLen)) = @SubString)
                begin
                    if ((select CHARINDEX(@SubString ,@InputString)) > 0)
                        begin
                        set @Count = @Count +1
                        end
                end
                                Set @K=@k+1
        end

end

As of Swift 2.1 NSArrays have containsObjectthat can be used like so:

if myArray.containsObject(objectImCheckingFor){
    //myArray has the objectImCheckingFor
}

1 - remove the margin from your BODY CSS.

2 - wrap all of your html in a wrapper <div id="wrapper"> ... all your body content </div>

3 - Define the CSS for the wrapper:

This will hold everything together, centered on the page.

#wrapper {
    margin-left:auto;
    margin-right:auto;
    width:960px;
}

I got this error because my AdonisJS server was not running before I ran the test. Running the server first fixed it.

Try numpy.clip:

>>> import numpy
>>> a = numpy.arange(-10, 10)
>>> a
array([-10,  -9,  -8,  -7,  -6,  -5,  -4,  -3,  -2,  -1,   0,   1,   2,
         3,   4,   5,   6,   7,   8,   9])
>>> a.clip(0, 10)
array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

You can clip only the bottom half with clip(0).

>>> a = numpy.array([1, 2, 3, -4, 5])
>>> a.clip(0)
array([1, 2, 3, 0, 5])

You can clip only the top half with clip(max=n). (This is much better than my previous suggestion, which involved passing NaN to the first parameter and using out to coerce the type.):

>>> a.clip(max=2)
array([ 1,  2,  2, -4,  2])

Another interesting approach is to use where:

>>> numpy.where(a <= 2, a, 2)
array([ 1,  2,  2, -4,  2])

Finally, consider aix's answer. I prefer clip for simple operations because it's self-documenting, but his answer is preferable for more complex operations.

Using a little different approach, you can use try catch, with throw statement.

function name() {
    try {
        ...

        //get out of here
        if (a == 'stop')
            throw "exit";

        ...
    } catch (e) {
        // TODO: handle exception
    }
}

You can easily achieve this with the use of jQuery .toggle().

$("#btnDisplay").click(function() {
  $("#div1").toggle();
  $("#div2").toggle();
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="div1">
  First Div
</div>
<div id="div2" style="display: none;">
  Second Div
</div>
<button id="btnDisplay">Display</button>

Try something like this:

<html>
  <body>

    <script type="text/javascript">
        function doSomething(event) {
          var source = event.target || event.srcElement;
          console.log(source);
          alert('test');
          if(window.event) {
            // IE8 and earlier
            // doSomething
           } else if(e.which) {
            // IE9/Firefox/Chrome/Opera/Safari
            // doSomething
           }
        }
     </script>

    <button onclick="doSomething('param')" id="id_button">
      action
    </button>

  </body>      
</html>

If you download bootstrap with the SASS files you will be able to edit the config file where there are a setting for the margin of the columns and then save it, in that way the SASS calculates the new width of the columns

I can see a number of reasons:

Readability

string s = string.Format("Hey, {0} it is the {1}st day of {2}.  I feel {3}!", _name, _day, _month, _feeling);

vs:

string s = "Hey," + _name + " it is the " + _day + "st day of " + _month + ".  I feel " + feeling + "!";

Format Specifiers (and this includes the fact you can write custom formatters)

string s = string.Format("Invoice number: {0:0000}", _invoiceNum);

vs:

string s = "Invoice Number = " + ("0000" + _invoiceNum).Substr(..... /*can't even be bothered to type it*/)

String Template Persistence

What if I want to store string templates in the database? With string formatting:

_id         _translation
  1         Welcome {0} to {1}.  Today is {2}.
  2         You have {0} products in your basket.
  3         Thank-you for your order.  Your {0} will arrive in {1} working days.

vs:

_id         _translation
  1         Welcome
  2         to
  3         .  Today is
  4         . 
  5         You have
  6         products in your basket.
  7         Someone
  8         just shoot
  9         the developer.

The only difference between files that causing the issue is the 8th byte of file

MoreLinq has IEnumerable<T>.ForEach and a ton of other useful extensions. It's probably not worth taking the dependency just for ForEach, but there's a lot of useful stuff in there.

• Press Ctrl + Shift + F

  

• Click on 3 dots under search box.

• Type your query in search box

• Type ./FOLDERNAME in files to include box and click Enter

Alternative way to this is, Right click on folder and select Find in Folder

You can use a combiation of LEFT and CHARINDEX to find the index of the first space, and then grab everything to the left of that.

 SELECT LEFT(YourColumn, charindex(' ', YourColumn) - 1) 

And in case any of your columns don't have a space in them:

SELECT LEFT(YourColumn, CASE WHEN charindex(' ', YourColumn) = 0 THEN 
    LEN(YourColumn) ELSE charindex(' ', YourColumn) - 1 END)

Opposite up is children(), but opposite in position is prepend(). Here a very good tutorial.

You can use round function

round("10.221",2);

Will return 10.22

1) Your Express project filesystem maybe like:

/ ...
/lib
/node_modules
/public
/views
      app.js
      config.json
      package.json

app.js - you global app container

2) Module main file (lib/mymodule/index.js):

var express = require('express');    
var app = module.exports = express();
// and load module dependencies ...  

// this place to set module settings
app.set('view engine', 'jade');
app.set('views', __dirname + '/views');

// then do module staff    
app.get('/mymodule/route/',function(req,res){ res.send('module works!') });

3) Connect module in main app.js

...
var mymodule = require('mymodule');
app.use(mymodule);

4) Sample logic

lib/login
lib/db
lib/config
lib/users
lib/verify
lib/
   /api/ 
   ...
lib/
   /admin/
      /users/
      /settings/
      /groups/
...

• Best for testing
• Best for scale
• Separate depends by module
• Grouping route by functionality (or modules)

tj says/show on Vimeo interesting idea how modularize express application - Modular web applications with Node.js and Express. Powerful and simple.

Why none of you use this?

 ''.join(filter(str.isalnum, s)) 

Too slow?

Don't use exceptions for flow control. Use DateTime.TryParse and DateTime.TryParseExact. Personally I prefer TryParseExact with a specific format, but I guess there are times when TryParse is better. Example use based on your original code:

DateTime value;
if (!DateTime.TryParse(startDateTextBox.Text, out value))
{
    startDateTextox.Text = DateTime.Today.ToShortDateString();
}

Reasons for preferring this approach:

• Clearer code (it says what it wants to do)
• Better performance than catching and swallowing exceptions
• This doesn't catch exceptions inappropriately - e.g. OutOfMemoryException, ThreadInterruptedException. (Your current code could be fixed to avoid this by just catching the relevant exception, but using TryParse would still be better.)

Set libraries search path first:

LINK_DIRECTORIES(${CMAKE_BINARY_DIR}/res)

And then just do

TARGET_LINK_LIBRARIES(GLBall mylib)

Can also do more dynamic inits with fill, e.g.

Array.fill(10){scala.util.Random.nextInt(5)} 

==>

Array[Int] = Array(0, 1, 0, 0, 3, 2, 4, 1, 4, 3)

Can't test it right now, but:

select * from tablename where date >= dateadd(day, datediff(day, 1, getdate()), 0) and date < dateadd(day, datediff(day, 0, getdate()), 0)

Personally, I would shorten it a touch too if all you need is the columns:

For i = LBound(arr1) To UBound(arr1)
    Sheets("SheetA").Columns(arr1(i)).Copy
    Sheets("SheetB").Columns(arr2(i)).PasteSpecial xlPasteValues
    Application.CutCopyMode = False
Next

as from this code snippet, there isnt much point in lastrow or firstrowDB

using List Comprehension:

>>> L = [1]*5
>>> [x+1 for x in L]
[2, 2, 2, 2, 2]
>>> 

which roughly translates to using a for loop:

>>> newL = []
>>> for x in L:
...     newL+=[x+1]
... 
>>> newL
[2, 2, 2, 2, 2]

or using map:

>>> map(lambda x:x+1, L)
[2, 2, 2, 2, 2]
>>> 

Pre C# 6.0 solution

You can use this to get a name of any provided member:

public static class MemberInfoGetting
{
    public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
    {
        MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
        return expressionBody.Member.Name;
    }
}

To get name of a variable:

string testVariable = "value";
string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => testVariable);

To get name of a parameter:

public class TestClass
{
    public void TestMethod(string param1, string param2)
    {
        string nameOfParam1 = MemberInfoGetting.GetMemberName(() => param1);
    }
}

C# 6.0 and higher solution

You can use the nameof operator for parameters, variables and properties alike:

string testVariable = "value";
string nameOfTestVariable = nameof(testVariable);

sp_who2 will actually provide a list of connections for the database server, not a database. To view connections for a single database (YourDatabaseName in this example), you can use

DECLARE @AllConnections TABLE(
    SPID INT,
    Status VARCHAR(MAX),
    LOGIN VARCHAR(MAX),
    HostName VARCHAR(MAX),
    BlkBy VARCHAR(MAX),
    DBName VARCHAR(MAX),
    Command VARCHAR(MAX),
    CPUTime INT,
    DiskIO INT,
    LastBatch VARCHAR(MAX),
    ProgramName VARCHAR(MAX),
    SPID_1 INT,
    REQUESTID INT
)

INSERT INTO @AllConnections EXEC sp_who2

SELECT * FROM @AllConnections WHERE DBName = 'YourDatabaseName'

(Adapted from SQL Server: Filter output of sp_who2.)

I ran into this issue when using IntelliJ 14's bundled Maven 3 instance.

I switched to using my own local Maven instance, via:

Settings -> Build, Execution, Deployment -> Build Tools -> Maven -> Maven Home Directory

Then added the path to my locally installed instance.

This got the dependencies to magically appear.

If the answers must be constrained to Google Sheets, this answer works but it has limitations and is clumsy enough UX that it may be hard to get others to adopt. In trying to solve this problem I've found that, for many applications, Airtable solves this by allowing for multi-select columns and the UX is worlds better.

This is old post but here is the one my solution in JavaScript what using jQuery library.

<script>
(function($){
    var download = [];
    $('a.force-download, .force-download a').each(function(){
        // Collect info
        var $this = $(this),
            $href = $this.attr('href'),
            $split = $href.split('/'),
            $name = document.title.replace(/[\W_]/gi, '-').replace(/-{2,}/g, '-'); // get title and clean it for the URL

        // Get filename from URL
        if($split[($split.length-1)])
        {
            $tmp = $split[($split.length-1)];
            $tmp = $tmp.split('.');
            $name = $tmp[0].replace(/[\W_]/gi, '-').replace(/-{2,}/g, '-');
        }

        // If name already exists, put timestamp there
        if($.inArray($name, download) > -1)
        {
            $name = $name + '-' + Date.now().replace(/[\W]/gi, '-');
        }

        $(this).attr("download", $name);
        download.push($name);
    });
}(jQuery || window.jQuery))
</script>

You just need to use class force-download inside your <a> tag and will force download automaticaly. You also can add it to parent div and will pickup all links inside it.

Example:

<a href="/some/good/url/Post-Injection_Post-Surgery_Instructions.pdf" class="force-download" target="_blank">Download PDF</a>

This is great for WordPress and any other systems or custom websites.

final class MySingleton {
     private init() {}
     static let shared = MySingleton()
}

Then call it;

let shared = MySingleton.shared

import java.io.*;
class Initials {

    public static void main(String args[]) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String s;
        char x;
        int l;
        System.out.print("Enter any sentence: ");
        s = br.readLine();
        s = " " + s; //adding a space infront of the inputted sentence or a name
        s = s.toUpperCase(); //converting the sentence into Upper Case (Capital Letters)
        l = s.length(); //finding the length of the sentence
        System.out.print("Output = ");

        for (int i = 0; i < l; i++) {
            x = s.charAt(i); //taking out one character at a time from the sentence
            if (x == ' ') //if the character is a space, printing the next Character along with a fullstop
                System.out.print(s.charAt(i + 1) + ".");
        }
    }
}

PhpStorm 2020

1. Help -> Edit Custom Properties.
2. File will open in Editor. Paste the section below to the file.

 #---------------------------------------------------------------------
 # Maximum file size (kilobytes) IDE should provide code assistance for.
 # The larger file is the slower its editor works and higher overall system memory 
 requirements are
 # if code assistance is enabled. Remove this property or set to very large number 
 if you need
 # code assistance for any files available regardless their size.
 #---------------------------------------------------------------------
 idea.max.intellisense.filesize=2500

3. File -> Invalidate / Restart -> Restart

This might not update sometimes and you might need to edit the root idea.properties file.

To edit this file for any version of Idea

1. Go to application location i.e linux => /opt/PhpStorm[version]/bin
2. Find file called idea.properties Make backup of file i.e idea.properties.old
3. Open original with any txt editor.
4. Find idea.max.intellisense.filesize=
5. Replace with idea.max.intellisense.filesize=your_required_size i.e idea.max.intellisense.filesize=10480 NB by default this size is in kb
6. Save and restart the IDE.

This Answer should work in most situations. Notice however how the filenames are stored in the tar file as, for example, ./file1 rather than just file1. I found that this caused problems when using this method to manipulate tarballs used as package files in BuildRoot.

One solution is to use some Bash globs to list all files except for .. like this:

tar -C my_dir -zcvf my_dir.tar.gz .[^.]* ..?* *

This is a trick I learnt from this answer.

Now tar will return an error if there are no files matching ..?* or .[^.]* , but it will still work. If the error is a problem (you are checking for success in a script), this works:

shopt -s nullglob
tar -C my_dir -zcvf my_dir.tar.gz .[^.]* ..?* *
shopt -u nullglob

Though now we are messing with shell options, we might decide that it is neater to have * match hidden files:

shopt -s dotglob
tar -C my_dir -zcvf my_dir.tar.gz *
shopt -u dotglob

This might not work where your shell globs * in the current directory, so alternatively, use:

shopt -s dotglob
cd my_dir
tar -zcvf ../my_dir.tar.gz *
cd ..
shopt -u dotglob

You can take a look at this article. It makes use of registry to read the list of installed applications.

public void GetInstalledApps()
{
    string uninstallKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
    using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(uninstallKey))
    {
        foreach (string skName in rk.GetSubKeyNames())
        {
            using (RegistryKey sk = rk.OpenSubKey(skName))
            {
                try
                {

                catch (Exception ex)

        }
    }
}

dG will delete from the current line to the end of file

dCtrl+End will delete from the cursor to the end of the file

But if this file is as large as you say, you may be better off reading the first few lines with head rather than editing and saving the file.

head hugefile > firstlines

(If you are on Windows you can use the Win32 port of head)

Actually there is a workaround. Copy the entire method, modify it's name, e.g. originalName() to originalName2() but modify the variable inside to take on whatever value you want, or pass it in as a parameter.

Then if you call this method directly from the console, it will have the same functionality but you will be able to modify the variable values.

If the method is called automatically then instead type into the console

originalName = null;
function originalName(original params..)
{
    alert("modified internals");
    add whatever original code you want
}

Loop through it and call toString. There isn't a magic way, and if there were, what do you think it would be doing under the covers other than looping through it? About the only micro-optimization would be to use StringBuilder instead of String, and even that isn't a huge win - concatenating strings turns into StringBuilder under the covers, but at least if you write it that way you can see what's going on.

StringBuilder out = new StringBuilder();
for (Object o : list)
{
  out.append(o.toString());
  out.append("\t");
}
return out.toString();

There is one additional step to Amber's answer if you're using a centralized repository:

git push -f to force the update of the central repository.

Be careful that there are not a lot of people working on the same branch because it can ruin consistency.

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

You can simply call filter multiple times:

query = meta.Session.query(User).filter(User.firstname.like(searchVar1)). \
                                 filter(User.lastname.like(searchVar2))

string ip = ((IPEndPoint)(testsocket.RemoteEndPoint)).Address.ToString();

With procrun you need to copy prunsrv to the application directory (download), and create an install.bat like this:

set PR_PATH=%CD%
SET PR_SERVICE_NAME=MyService
SET PR_JAR=MyService.jar
SET START_CLASS=org.my.Main
SET START_METHOD=main
SET STOP_CLASS=java.lang.System
SET STOP_METHOD=exit
rem ; separated values
SET STOP_PARAMS=0
rem ; separated values
SET JVM_OPTIONS=-Dapp.home=%PR_PATH%
prunsrv.exe //IS//%PR_SERVICE_NAME% --Install="%PR_PATH%\prunsrv.exe" --Jvm=auto --Startup=auto --StartMode=jvm --StartClass=%START_CLASS% --StartMethod=%START_METHOD% --StopMode=jvm --StopClass=%STOP_CLASS% --StopMethod=%STOP_METHOD% ++StopParams=%STOP_PARAMS% --Classpath="%PR_PATH%\%PR_JAR%" --DisplayName="%PR_SERVICE_NAME%" ++JvmOptions=%JVM_OPTIONS%

I presume to

• run this from the same directory where the jar and prunsrv.exe is
• the jar has its working MANIFEST.MF
• and you have shutdown hooks registered into JVM (for example with context.registerShutdownHook() in Spring)...
• not using relative paths for files outside the jar (for example log4j should be used with log4j.appender.X.File=${app.home}/logs/my.log or something alike)

Check the procrun manual and this tutorial for more information.

You can use each()

$('#id-submit').click(function () {
      $(":input").each(function(){
          this.value = this.value.toUpperCase();          
      });
});

How to run a shell script from a Perl program

1. Using system system($command, @arguments);

For example:

system("sh", "script.sh", "--help" );

system("sh script.sh --help");

System will execute the $command with @arguments and return to your script when finished. You may check $! for certain errors passed to the OS by the external application. Read the documentation for system for the nuances of how various invocations are slightly different.

2. Using exec

This is very similar to the use of system, but it will terminate your script upon execution. Again, read the documentation for exec for more.

3. Using backticks or qx//

my $output = `script.sh --option`;

my $output = qx/script.sh --option/;

The backtick operator and it's equivalent qx//, excute the command and options inside the operator and return that commands output to STDOUT when it finishes.

There are also ways to run external applications through creative use of open, but this is advanced use; read the documentation for more.

For me it works well:

>>> import numpy as np
>>> a = np.array([1, 2, 3, 1, 2, 3])
>>> np.where(a > 2)[0]
[2 5]

Simply:

1. Right click on your project.

2. Go to properties.

3. Select android (second option in the Left panel).

4. Click "add..." (in library), select your project.

5. Click ok.

6. And finally, clean your project.

If this doesn't work, make sure that "android-support-v7-appcompat" is in your Project Explorer.

If it isn't there, you can add it by importing a simple project from: C:/android-sdks\extras\android\support\v7\appcompat

For me, when I do Immediately invoked function, I need to put ; at the end of require().

Error:

const fs = require('fs')

(() => {
  console.log('wow')
})()

Good:

const fs = require('fs');

(() => {
  console.log('wow')
})()

Here is what I find works

1. Set a form name

2. Use a default select option, for example...

   <option value="-1" selected>Please Select</option>

So that if the form is submitted, use of JavaScript to halt the submission process can be implemented and verified at the server too.

3. Try to use HTML5 attributes now they are supported.

This input

<input type="submit">

should be

<input name="Submit" type="submit" value="Submit">

whenever I use a form that fails, it is a failure due to the difference in calling the button name submit and name as Submit.

You should also set your enctype attribute for your form as forms fail on my web host if it's not set.

Just the same way as you would do in normal Java code.

for (Map.Entry<String, String> entry : countries.entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();
    // ...
}

However, scriptlets (raw Java code in JSP files, those <% %> things) are considered a poor practice. I recommend to install JSTL (just drop the JAR file in /WEB-INF/lib and declare the needed taglibs in top of JSP). It has a <c:forEach> tag which can iterate over among others Maps. Every iteration will give you a Map.Entry back which in turn has getKey() and getValue() methods.

Here's a basic example:

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

<c:forEach items="${map}" var="entry">
    Key = ${entry.key}, value = ${entry.value}<br>
</c:forEach>

Thus your particular issue can be solved as follows:

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

<select name="country">
    <c:forEach items="${countries}" var="country">
        <option value="${country.key}">${country.value}</option>
    </c:forEach>
</select>

You need a Servlet or a ServletContextListener to place the ${countries} in the desired scope. If this list is supposed to be request-based, then use the Servlet's doGet():

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    Map<String, String> countries = MainUtils.getCountries();
    request.setAttribute("countries", countries);
    request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response);
}

Or if this list is supposed to be an application-wide constant, then use ServletContextListener's contextInitialized() so that it will be loaded only once and kept in memory:

public void contextInitialized(ServletContextEvent event) {
    Map<String, String> countries = MainUtils.getCountries();
    event.getServletContext().setAttribute("countries", countries);
}

In both cases the countries will be available in EL by ${countries}.

Hope this helps.

You can also use the RestSharp library for example

var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");            
client.Authenticator = new HttpBasicAuthenticator(userName, password);            
var request = new RestRequest(Method.POST); 
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");            
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

add android:focusableInTouchMode="true" in root layout, when edit text will be clicked at that time cursor will be shown.

I don't know why, but for some reason, the "/bin/bash" version didn't work for me. Instead, the simpler version worked, following the example given here at Oracle Docs.

String[] args = new String[] {"ping", "www.google.com"};
Process proc = new ProcessBuilder(args).start();

You have to leave Python 2.4 installed on RHEL/Centos; otherwise, tools start breaking. You can do a dual-install, though; I talk about this here:

http://thebuild.com/blog/2009/10/17/wordpress-to-djangopostgresql-part-3-installing-apache-python-2-6-psycopg2-and-mod_wsgi/

The post is about 2.6, but applies equally to 2.7.

Have you tried using the official JQueryUI implementation (not jQuery only) : ?

some people talk very well about PyInstaller

http://www.pyinstaller.org/

When you assign your variables "first_number" and "second_number", you need to change "document.getElementsById" to the singular "document.getElementById".

Have you considered letting the user of your application select their own color scheme? Without fail you won't be able to please all of your users with your selection but you can allow them to find what pleases them.

This is not REST. You cannot define URIs for resources inside your API. Resource navigation must be hypertext-driven. It's fine if you want pretty URIs and heavy amounts of coupling, but just do not call it REST, because it directly violates the constraints of RESTful architecture.

See this article by the inventor of REST.

The below regex would match white spaces but not of a new line character.

(?:(?!\n)\s)

DEMO

If you want to add carriage return also then add \r with the | operator inside the negative lookahead.

(?:(?![\n\r])\s)

DEMO

Add + after the non-capturing group to match one or more white spaces.

(?:(?![\n\r])\s)+

DEMO

I don't know why you people failed to mention the POSIX character class [[:blank:]] which matches any horizontal whitespaces (spaces and tabs). This POSIX chracter class would work on BRE(Basic REgular Expressions), ERE(Extended Regular Expression), PCRE(Perl Compatible Regular Expression).

DEMO

I made a sketchy benchmark on the three methods described in other responses.

Obviously pre-allocating the slice before pulling the keys is faster than appending, but surprisingly, the reflect.ValueOf(m).MapKeys() method is significantly slower than the latter:

? go run scratch.go
populating
filling 100000000 slots
done in 56.630774791s
running prealloc
took: 9.989049786s
running append
took: 18.948676741s
running reflect
took: 25.50070649s

Here's the code: https://play.golang.org/p/Z8O6a2jyfTH (running it in the playground aborts claiming that it takes too long, so, well, run it locally.)

I think in Postgres you can play with formats for example if you want dd/mm/yyyy

TO_CHAR(submit_time, 'DD/MM/YYYY') as submit_date

Allthough your src = encodeURI should work, I would have gone a different way:

var iframe = document.createElement('iframe');
var html = '<body>Foo</body>';
document.body.appendChild(iframe);
iframe.contentWindow.document.open();
iframe.contentWindow.document.write(html);
iframe.contentWindow.document.close();

As this has no x-domain restraints and is completely done via the iframe handle, you may access and manipulate the contents of the frame later on. All you need to make sure of is, that the contents have been rendered, which will (depending on browser type) start during/after the .write command is issued - but not nescessarily done when close() is called.

A 100% compatible way of doing a callback could be this approach:

<html><body onload="parent.myCallbackFunc(this.window)"></body></html>

Iframes has the onload event, however. Here is an approach to access the inner html as DOM (js):

iframe.onload = function() {
   var div=iframe.contentWindow.document.getElementById('mydiv');
};

None of these worked for me. I had to go to a SuperUser question.

If it is a System Process—PID 4—you need to disable the HTTP.sys driver which is started on demand by another service, such as Windows Remote Management or Print Spooler on Windows 7 or 2008.

There is two ways to disable it but the first one is safer:

1. • Go to device manager, select “show hidden devices” from menu/view, go to “Non-Plug and Play Driver”/HTTP, double click it to disable it (or set it to manual, some services depended on it).

   • Reboot and use netstat -nao | find ":80" to check if 80 is still used.

This is the one that worked for me!

strip() is a method for strings, you are calling it on a list, hence the error.

>>> 'strip' in dir(str)
True
>>> 'strip' in dir(list)
False

To do what you want, just do

>>> l = ['Facebook;Google+;MySpace', 'Apple;Android']
>>> l1 = [elem.strip().split(';') for elem in l]
>>> print l1
[['Facebook', 'Google+', 'MySpace'], ['Apple', 'Android']]

Since, you want the elements to be in a single list (and not a list of lists), you have two options.

1. Create an empty list and append elements to it.
2. Flatten the list.

To do the first, follow the code:

>>> l1 = []
>>> for elem in l:
        l1.extend(elem.strip().split(';'))  
>>> l1
['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']

To do the second, use itertools.chain

>>> l1 = [elem.strip().split(';') for elem in l]
>>> print l1
[['Facebook', 'Google+', 'MySpace'], ['Apple', 'Android']]
>>> from itertools import chain
>>> list(chain(*l1))
['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5. From the comment you put this needed to be declared elsewhere in your code

$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider

The error was because you are trying to execute a method that does not exist.

PowerShell by default allows this to happen as defined its StrictMode

When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.

In order to use nslookup, host or gethostbyname() then the target's name will need to be registered with DNS or statically defined in the hosts file on the machine running your program. Yes, you could connect to the target with SSH or some other application and query it directly, but for a generic solution you'll need some sort of DNS entry for it.

See .offset() here in the jQuery doc. It gives the position relative to the document, not to the parent. You perhaps have .offset() and .position() confused. If you want the position in the window instead of the position in the document, you can subtract off the .scrollTop() and .scrollLeft() values to account for the scrolled position.

Here's an excerpt from the doc:

The .offset() method allows us to retrieve the current position of an element relative to the document. Contrast this with .position(), which retrieves the current position relative to the offset parent. When positioning a new element on top of an existing one for global manipulation (in particular, for implementing drag-and-drop), .offset() is the more useful.

To combine these:

var offset = $("selector").offset();
var posY = offset.top - $(window).scrollTop();
var posX = offset.left - $(window).scrollLeft(); 

You can try it here (scroll to see the numbers change): http://jsfiddle.net/jfriend00/hxRPQ/

To get a type that implements io.Reader from a []byte slice, you can use bytes.NewReader in the bytes package:

r := bytes.NewReader(byteData)

This will return a value of type bytes.Reader which implements the io.Reader (and io.ReadSeeker) interface.

Don't worry about them not being the same "type". io.Reader is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types.

Using the .val() function on a multi-select list will return an array of the selected values:

var selectedValues = $('#multipleSelect').val();

and in your html:

<select id="multipleSelect" multiple="multiple">
    <option value="1">Text 1</option>
    <option value="2">Text 2</option>
    <option value="3">Text 3</option>
</select>

Here is the version 2.0.0 for Mac OSx:

Android Context has the following method:

public abstract boolean deleteFile (String name)

I believe this will do what you want with the right App premissions as listed above.

For my case gulp-ignore was perfect. As option you may pass a function there:

function condition(file) {
 // do whatever with file.path
 // return boolean true if needed to exclude file 
}

And the task would look like this:

var gulpIgnore = require('gulp-ignore');

gulp.task('task', function() {
  gulp.src('./**/*.js')
    .pipe(gulpIgnore.exclude(condition))
    .pipe(gulp.dest('./dist/'));
});

I feel your pain ... yet another date time format... just what you needed!

Using Web Api 2 you can use route attributes to specify parameters.

so with attributes on your class and your method you can code up a REST URL using this utc format you are having trouble with (apparently its ISO8601, presumably arrived at using startDate.toISOString())

[Route(@"daterange/{startDate:regex(^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}.\d{3}Z$)}/{endDate:regex(^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}.\d{3}Z$)}")]
    [HttpGet]
    public IEnumerable<MyRecordType> GetByDateRange(DateTime startDate, DateTime endDate)

.... BUT, although this works with one date (startDate), for some reason it doesnt work when the endDate is in this format ... debugged for hours, only clue is exception says it doesnt like colon ":" (even though web.config is set with :

<system.web>
    <compilation debug="true" targetFramework="4.5.1" />
    <httpRuntime targetFramework="4.5.1" requestPathInvalidCharacters="" />
</system.web>

So, lets make another date format (taken from the polyfill for the ISO date format) and add it to the Javascript date (for brevity, only convert up to minutes):

if (!Date.prototype.toUTCDateTimeDigits) {
    (function () {

        function pad(number) {
            if (number < 10) {
                return '0' + number;
            }
            return number;
        }

        Date.prototype.toUTCDateTimeDigits = function () {
            return this.getUTCFullYear() +
              pad(this.getUTCMonth() + 1) +
              pad(this.getUTCDate()) +
              'T' +
              pad(this.getUTCHours()) +
              pad(this.getUTCMinutes()) +
              'Z';
        };

    }());
}

Then when you send the dates to the Web API 2 method, you can convert them from string to date:

[RoutePrefix("api/myrecordtype")]
public class MyRecordTypeController : ApiController
{


    [Route(@"daterange/{startDateString}/{endDateString}")]
    [HttpGet]
    public IEnumerable<MyRecordType> GetByDateRange([FromUri]string startDateString, [FromUri]string endDateString)
    {
        var startDate = BuildDateTimeFromYAFormat(startDateString);
        var endDate = BuildDateTimeFromYAFormat(endDateString);
    ...
    }

    /// <summary>
    /// Convert a UTC Date String of format yyyyMMddThhmmZ into a Local Date
    /// </summary>
    /// <param name="dateString"></param>
    /// <returns></returns>
    private DateTime BuildDateTimeFromYAFormat(string dateString)
    {
        Regex r = new Regex(@"^\d{4}\d{2}\d{2}T\d{2}\d{2}Z$");
        if (!r.IsMatch(dateString))
        {
            throw new FormatException(
                string.Format("{0} is not the correct format. Should be yyyyMMddThhmmZ", dateString)); 
        }

        DateTime dt = DateTime.ParseExact(dateString, "yyyyMMddThhmmZ", CultureInfo.InvariantCulture, DateTimeStyles.AssumeUniversal);

        return dt;
    }

so the url would be

http://domain/api/myrecordtype/daterange/20140302T0003Z/20140302T1603Z

Hanselman gives some related info here:

http://www.hanselman.com/blog/OnTheNightmareThatIsJSONDatesPlusJSONNETAndASPNETWebAPI.aspx

The same way you declare any other variable, just use the bit type:

DECLARE @MyVar bit
Set @MyVar = 1  /* True */
Set @MyVar = 0  /* False */

SELECT * FROM [MyTable] WHERE MyBitColumn = @MyVar

This should do the trick:

public static Bitmap getBitmapFromURL(String src) {
    try {
        URL url = new URL(src);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
} // Author: silentnuke

Don't forget to add the internet permission in your manifest.

If it is a string then use the built in float on it to do the conversion for instance: print( "%.5f" % float("1.43572e-03")) answer:0.00143572
