No for the moment.

I doubt it will be possible for the future for ActiveX support will be discontinued in near future (as MS stated).

Look here about HTML Object tag, but not anything will be accepted. You should try.

There is no official datepicker for bootstrap; as such, you should explicitly state which one you're using.

If you're using eternicode/bootstrap-datepicker, there's a startDate option. As discussed directly under the Options section in the README:

All options that take a "Date" can handle a Date object; a String formatted according to the given format; or a timedelta relative to today, eg '-1d', '+6m +1y', etc, where valid units are 'd' (day), 'w' (week), 'm' (month), and 'y' (year).

So you would do:

$('#datepicker').datepicker({
    startDate: '+1d'
})

You are not creating a separate dictionary for each iframe, you just keep modifying the same dictionary over and over, and you keep adding additional references to that dictionary in your list.

Remember, when you do something like content.append(info), you aren't making a copy of the data, you are simply appending a reference to the data.

You need to create a new dictionary for each iframe.

for iframe in soup.find_all('iframe'):
   info = {}
    ...

Even better, you don't need to create an empty dictionary first. Just create it all at once:

for iframe in soup.find_all('iframe'):
    info = {
        "src":    iframe.get('src'),
        "height": iframe.get('height'),
        "width":  iframe.get('width'),
    }
    content.append(info)

There are other ways to accomplish this, such as iterating over a list of attributes, or using list or dictionary comprehensions, but it's hard to improve upon the clarity of the above code.

As drew_w said, you can find a good example here.

JSFIDDLE

insert into bookmarks (users_id, lessoninfo_id)

select 1, 167
EXCEPT
select user_id, lessoninfo_id
from bookmarks
where user_id=1
and lessoninfo_id=167;

This is the fastest way.

For some other SQL engines, you can use a Dummy table containing 1 record. e.g:

select 1, 167 from ONE_RECORD_DUMMY_TABLE

Simple

var a=[{a:4}], b=[{b:5}]

angular.merge(a,b) // [{a:4, b:5}]

Here is a sample tokenizer class that might do what you want

//Header file
class Tokenizer 
{
    public:
        static const std::string DELIMITERS;
        Tokenizer(const std::string& str);
        Tokenizer(const std::string& str, const std::string& delimiters);
        bool NextToken();
        bool NextToken(const std::string& delimiters);
        const std::string GetToken() const;
        void Reset();
    protected:
        size_t m_offset;
        const std::string m_string;
        std::string m_token;
        std::string m_delimiters;
};

//CPP file
const std::string Tokenizer::DELIMITERS(" \t\n\r");

Tokenizer::Tokenizer(const std::string& s) :
    m_string(s), 
    m_offset(0), 
    m_delimiters(DELIMITERS) {}

Tokenizer::Tokenizer(const std::string& s, const std::string& delimiters) :
    m_string(s), 
    m_offset(0), 
    m_delimiters(delimiters) {}

bool Tokenizer::NextToken() 
{
    return NextToken(m_delimiters);
}

bool Tokenizer::NextToken(const std::string& delimiters) 
{
    size_t i = m_string.find_first_not_of(delimiters, m_offset);
    if (std::string::npos == i) 
    {
        m_offset = m_string.length();
        return false;
    }

    size_t j = m_string.find_first_of(delimiters, i);
    if (std::string::npos == j) 
    {
        m_token = m_string.substr(i);
        m_offset = m_string.length();
        return true;
    }

    m_token = m_string.substr(i, j - i);
    m_offset = j;
    return true;
}

Example:

std::vector <std::string> v;
Tokenizer s("split this string", " ");
while (s.NextToken())
{
    v.push_back(s.GetToken());
}

I have the same problem here, you may use the $GLOBALS array.

$GLOBALS["variable"] = "123";
include ("my.php");

It should also run doing this:

$myvar = "123";
include ("my.php");

....

echo $GLOBALS["myvar"];

Have a nice day.

Thanks Sanoj, that worked for me.
However iOS does not support "onbeforeunload" on iPhone. Workaround for me was to set localStorage with js:

<button onclick="myFunction()">Click me</button>

<script>
document.addEventListener("DOMContentLoaded", function(event) { 
            var scrollpos = localStorage.getItem('scrollpos');
            if (scrollpos) window.scrollTo(0, scrollpos);
        });
function myFunction() {
  localStorage.setItem('scrollpos', window.scrollY);
  location.reload(); 
}
</script>

You can also try another library - https://github.com/wikimedia/jquery.i18n .

In addition to parameter replacement and multiple plural forms, it has support for gender a rather unique feature of custom grammar rules that some languages need.

You can escape % using %% for XML parser, but it is shown twice in device.

To show it once, try following format: \%%

For Example

<string name="zone_50">Fat Burning (50\%% to 60\%%)</string> 

is shown as Fat Burning (50% to 60%) in device

Try this

SELECT CONVERT(varchar(11),getdate(),101) -- Converts to 'mm/dd/yyyy'

SELECT CONVERT(varchar(11),getdate(),103) -- Converts to 'dd/mm/yyyy'

Whether null char is allowed or not really depends on base64 codec in question. Given vagueness of Base64 standard (there is no authoritative exact specification), many implementations would just ignore it as white space. And then others can flag it as a problem. And buggiest ones wouldn't notice and would happily try decoding it... :-/

But it sounds c# implementation does not like it (which is one valid approach) so if removing it helps, that should be done.

One minor additional comment: UTF-8 is not a requirement, ISO-8859-x aka Latin-x, and 7-bit Ascii would work as well. This because Base64 was specifically designed to only use 7-bit subset which works with all 7-bit ascii compatible encodings.

For me it turned out that I had a @JsonManagedReferece in one entity without a @JsonBackReference in the other referenced entity. This caused the marshaller to throw an error.

This steps are used in spring boot with self signed ssl certificate implementation

if SSL turns off then HTTPS call will be worked as expected.

https://localhost:8443/test/hello

These are the steps we have to follow,

1. Generate self signed ssl certificate

keytool -genkeypair -alias tomcat -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650

after key generation has done then copy that file in to the resource foder in your project

2. add key store properties in applicaiton.properties

server.port: 8443
server.ssl.key-store:classpath:keystore.p12
server.ssl.key-store-password: test123
server.ssl.keyStoreType: PKCS12
server.ssl.keyAlias: tomcat

3. change your postman ssl verification settings to turn OFF

now verify the url: https://localhost:8443/test/hello

startdate = moment().subtract(1, 'days').format('DD-MM-YYYY');

An element with ‘display: block’ (as div is by default) has a width determined by the width of its container. You can't make a block's width dependent on the width of its contents (shrink-to-fit).

(Except for blocks that are ‘float: left/right’ in CSS 2.1, but that's no use for centering.)

You could set the ‘display’ property to ‘inline-block’ to turn a block into a shrink-to-fit object that can be controlled by its parent's text-align property, but browser support is spotty. You can mostly get away with it by using hacks (eg. see -moz-inline-stack) if you want to go that way.

The other way to go is tables. This can be necessary when you have columns whose width really can't be known in advance. I can't really tell what you're trying to do from the example code — there's nothing obvious in there that would need a shrink-to-fit block — but a list of products could possibly be considered tabular.

[PS. never use ‘pt’ for font sizes on the web. ‘px’ is more reliable if you really need fixed size text, otherwise relative units like ‘%’ are better. And “clear: ccc both” — a typo?]

.center{
   text-align:center; 
}

.center > div{ /* N.B. child combinators don't work in IE6 or less */
   display:inline-block;
}

What is the real difference between one-to-many and many-to-one relationship?

There are conceptual differences between these terms that should help you visualize the data and also possible differences in the generated schema that should be fully understood. Mostly the difference is one of perspective though.

In a one-to-many relationship, the local table has one row that may be associated with many rows in another table. In the example from SQL for beginners, one Customer may be associated to many Orders.

In the opposite many-to-one relationship, the local table may have many rows that are associated with one row in another table. In our example, many Orders may be associated to one Customer. This conceptual difference is important for mental representation.

In addition, the schema which supports the relationship may be represented differently in the Customer and Order tables. For example, if the customer has columns id and name:

id,name
1,Bill Smith
2,Jim Kenshaw

Then for a Order to be associated with a Customer, many SQL implementations add to the Order table a column which stores the id of the associated Customer (in this schema customer_id:

id,date,amount,customer_id
10,20160620,12.34,1
11,20160620,7.58,1
12,20160621,158.01,2

In the above data rows, if we look at the customer_id id column, we see that Bill Smith (customer-id #1) has 2 orders associated with him: one for $12.34 and one for $7.58. Jim Kenshaw (customer-id #2) has only 1 order for $158.01.

What is important to realize is that typically the one-to-many relationship doesn't actually add any columns to the table that is the "one". The Customer has no extra columns which describe the relationship with Order. In fact the Customer might also have a one-to-many relationship with ShippingAddress and SalesCall tables and yet have no additional columns added to the Customer table.

However, for a many-to-one relationship to be described, often an id column is added to the "many" table which is a foreign-key to the "one" table -- in this case a customer_id column is added to the Order. To associated order #10 for $12.34 to Bill Smith, we assign the customer_id column to Bill Smith's id 1.

However, it is also possible for there to be another table that describes the Customer and Order relationship, so that no additional fields need to be added to the Order table. Instead of adding a customer_id field to the Order table, there could be Customer_Order table that contains keys for both the Customer and Order.

customer_id,order_id
1,10
1,11
2,12

In this case, the one-to-many and many-to-one is all conceptual since there are no schema changes between them. Which mechanism depends on your schema and SQL implementation.

Hope this helps.

With LINQ, you can transform the array of uninitialized elements into the new collection of created objects with one line of code.

var houses = new GameObject[200].Select(h => new GameObject()).ToArray();

Actually, you can use any other source for this, even generated sequence of integers:

var houses = Enumerable.Repeat(0, 200).Select(h => new GameObject()).ToArray();

However, the first case seems to me more readable, although the type of original sequence is not important.

You could use this function:

function RefreshTable(tableId, urlData)
    {
      //Retrieve the new data with $.getJSON. You could use it ajax too
      $.getJSON(urlData, null, function( json )
      {
        table = $(tableId).dataTable();
        oSettings = table.fnSettings();

        table.fnClearTable(this);

        for (var i=0; i<json.aaData.length; i++)
        {
          table.oApi._fnAddData(oSettings, json.aaData[i]);
        }

        oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
        table.fnDraw();
      });
    }

Dont' forget to call it after your delete function has succeded.

Equivalent in python would be:

>>> import time
>>> tic = time.clock()
>>> toc = time.clock()
>>> toc - tic

If you are trying to find the best performing method then you should probably have a look at timeit.

To change bottom line color, you can use this in your app theme:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <item name="colorControlNormal">#c5c5c5</item>
    <item name="colorControlActivated">#ffe100</item>
    <item name="colorControlHighlight">#ffe100</item>
</style>

To change floating label color write following theme:

<style name="TextAppearence.App.TextInputLayout" parent="@android:style/TextAppearance">
<item name="android:textColor">#4ffd04[![enter image description here][1]][1]</item>
</style>

and use this theme in your layout:

 <android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="20dp"
    app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout">

    <EditText
        android:id="@+id/edtTxtFirstName_CompleteProfileOneActivity"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:capitalize="characters"
        android:hint="User Name"
        android:imeOptions="actionNext"
        android:inputType="text"
        android:singleLine="true"
        android:textColor="@android:color/white" />

</android.support.design.widget.TextInputLayout>

Use the following query:

SELECT * FROM SAMPLE_TABLE ORDER BY ROWID ASC LIMIT 1

Could it be that you have not entered a commit message? According to their twitter feed: "New functionality added. Block users from committing work without writing a log message. Find in the resources section of your control panel".

Turn on the server log:

log_statement = all

This will log every call to the database server.

I would not use log_statement = all on a production server. Produces huge log files.
The manual about logging-parameters:

log_statement (enum)

Controls which SQL statements are logged. Valid values are none (off), ddl, mod, and all (all statements). [...]

Resetting the log_statement parameter requires a server reload (SIGHUP). A restart is not necessary. Read the manual on how to set parameters.

Don't confuse the server log with pgAdmin's log. Two different things!

You can also look at the server log files in pgAdmin, if you have access to the files (may not be the case with a remote server) and set it up correctly. In pgadmin III, have a look at: Tools -> Server status. That option was removed in pgadmin4.

I prefer to read the server log files with vim (or any editor / reader of your choice).

Quotes, but I prefer them on the just the value:

url: "http://www.example.com/"

Putting them across the whole line looks like it might cause problems.

You can get the raw data by calling ReadAsStringAsAsync on the Request.Content property.

string result = await Request.Content.ReadAsStringAsync();

There are various overloads if you want it in a byte or in a stream. Since these are async-methods you need to make sure your controller is async:

public async Task<IHttpActionResult> GetSomething()
{
    var rawMessage = await Request.Content.ReadAsStringAsync();
    // ...
    return Ok();
}

EDIT: if you're receiving an empty string from this method, it means something else has already read it. When it does that, it leaves the pointer at the end. An alternative method of doing this is as follows:

public IHttpActionResult GetSomething()
{
    var reader = new StreamReader(Request.Body);
    reader.BaseStream.Seek(0, SeekOrigin.Begin); 
    var rawMessage = reader.ReadToEnd();

    return Ok();
}

In this case, your endpoint doesn't need to be async (unless you have other async-methods)

Just replace -H with -h. Check man grep for more details on options

find . -name '*.bar' -exec grep -hn FOO {} \;

You will need to do two steps here for a complete solution

First click on the Solution that you have open and then go File-> Source Control -> Go Online Then uncheck all the files that are being shown as being modified while you were offline.

Don't do the Get Latest version from Source Control Explorer. That will result in a dialog potentially showing a bunch of files asking you to resolve conflicts. Instead do this

In source Control explorer right click on the folder you want to get latest of and then Advanced - Get Specific Version. In the dropdown for version type choose Latest and then choose the first check box that says Overwrite writable files that are not checked out. This will automatically bring your folder in sync with latest on the server

This could be accomplished with a single line of code:

IF OBJECT_ID('tempdb..#tempTableName') IS NOT NULL DROP TABLE #tempTableName;   

Using this.props.children is the idiomatic way to pass instantiated components to a react component

const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>

When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div or span):

const Label = props => <span>{props.children}</span>
const Button = props => {
    const Inner = props.inner; // Note: variable name _must_ start with a capital letter 
    return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>

If what you want to do is to pass a children-like parameter as a prop, you can do that:

const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />

After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.

Problem is caused by comma at the end of (in your case each) JSON object placed in the array:

{
    "number": "...",
    "title": ".." ,  //<- see that comma?
}

If you remove them your data will become

[
    {
        "number": "3",
        "title": "hello_world"
    }, {
        "number": "2",
        "title": "hello_world"
    }
]

and

Wrapper[] data = gson.fromJson(jElement, Wrapper[].class);

should work fine.

If you place your buttons inside a div with class "btn-group" the buttons inside will stretch to the same size as the largest button.

eg:

<div class="btn-group">
  <button type="button" class="btn btn-default">Left</button>
  <button type="button" class="btn btn-default">Middle</button>
  <button type="button" class="btn btn-default">Right</button>
</div> 

Bootstrap Button Groups

I found the issue. This is a firewall message and an error was occurring in the VB script due to wrong data in database, but the error was not logged/caught properly.

if you don't want .pyc anymore you can use this single line in a terminal:

export PYTHONDONTWRITEBYTECODE=1

if you change your mind:

unset PYTHONDONTWRITEBYTECODE

MVC is a controlled environment and MVVM is a reactive environment.

In a controlled environment you should have less code and a common source of logic; which should always live within the controller. However; in the web world MVC easily gets divided into view creation logic and view dynamic logic. Creation lives on the server and dynamic lives on the client. You see this a lot with ASP.NET MVC combined with AngularJS whereas the server will create a View and pass in a Model and send it to the client. The client will then interact with the View in which case AngularJS steps in to as a local controller. Once submitted the Model or a new Model is passed back to the server controller and handled. (Thus the cycle continues and there are a lot of other translations of this handling when working with sockets or AJAX etc but over all the architecture is identical.)

MVVM is a reactive environment meaning you typically write code (such as triggers) that will activate based on some event. In XAML, where MVVM thrives, this is all easily done with the built in databinding framework BUT as mentioned this will work on any system in any View with any programming language. It is not MS specific. The ViewModel fires (usually a property changed event) and the View reacts to it based on whatever triggers you create. This can get technical but the bottom line is the View is stateless and without logic. It simply changes state based on values. Furthermore, ViewModels are stateless with very little logic, and Models are the State with essentially Zero logic as they should only maintain state. I describe this as application state (Model), state translator (ViewModel), and then the visual state / interaction (View).

In an MVC desktop or client side application you should have a Model, and the Model should be used by the Controller. Based on the Model the controller will modify the View. Views are usually tied to Controllers with Interfaces so that the Controller can work with a variety of Views. In ASP.NET the logic for MVC is slightly backwards on the server as the Controller manages the Models and passes the Models to a selected View. The View is then filled with data based on the model and has it's own logic (usually another MVC set such as done with AngularJS). People will argue and get this confused with application MVC and try to do both at which point maintaining the project will eventually become a disaster. ALWAYS put the logic and control in one location when using MVC. DO NOT write View logic in the code behind of the View (or in the View via JS for web) to accommodate Controller or Model data. Let the Controller change the View. The ONLY logic that should live in a View is whatever it takes to create and run via the Interface it's using. An example of this is submitting a username and password. Whether desktop or web page (on client) the Controller should handle the submit process whenever the View fires the Submit action. If done correctly you can always find your way around an MVC web or local app easily.

MVVM is personally my favorite as it's completely reactive. If a Model changes state the ViewModel listens and translates that state and that's it!!! The View is then listening to the ViewModel for state change and it also updates based on the translation from the ViewModel. Some people call it pure MVVM but there's really only one and I don't care how you argue it and it's always Pure MVVM where the View contains absolutely no logic.

Here's a slight example: Let's say the you want to have a menu slide in on a button press. In MVC you will have a MenuPressed action in your interface. The Controller will know when you click the Menu button and then tell the View to slide in the Menu based on another Interface method such as SlideMenuIn. A round trip for what reason? Incase the Controller decides you can't or wants to do something else instead that's why. The Controller should be in charge of the View with the View doing nothing unless the Controller says so. HOWEVER; in MVVM the slide menu in animation should be built in and generic and instead of being told to slide it in will do so based on some value. So it listens to the ViewModel and when the ViewModel says, IsMenuActive = true (or however) the animation for that takes place. Now, with that said I want to make another point REALLY CLEAR and PLEASE pay attention. IsMenuActive is probably BAD MVVM or ViewModel design. When designing a ViewModel you should never assume a View will have any features at all and just pass translated model state. That way if you decide to change your View to remove the Menu and just show the data / options another way, the ViewModel doesn't care. So how would you manage the Menu? When the data makes sense that's how. So, one way to do this is to give the Menu a list of options (probably an array of inner ViewModels). If that list has data, the Menu then knows to open via the trigger, if not then it knows to hide via the trigger. You simply have data for the menu or not in the ViewModel. DO NOT decide to show / hide that data in the ViewModel.. simply translate the state of the Model. This way the View is completely reactive and generic and can be used in many different situations.

All of this probably makes absolutely no sense if you're not already at least slightly familiar with the architecture of each and learning it can be very confusing as you'll find ALOT OF BAD information on the net.

So... things to keep in mind to get this right. Decide up front how to design your application and STICK TO IT.

If you do MVC, which is great, then make sure you Controller is manageable and in full control of your View. If you have a large View consider adding controls to the View that have different Controllers. JUST DON'T cascade those controllers to different controllers. Very frustrating to maintain. Take a moment and design things separately in a way that will work as separate components... And always let the Controller tell the Model to commit or persist storage. The ideal dependency setup for MVC in is View ? Controller ? Model or with ASP.NET (don't get me started) Model ? View ? Controller ? Model (where Model can be the same or a totally different Model from Controller to View) ...of course the only need to know of Controller in View at this point is mostly for endpoint reference to know where back to pass a Model.

If you do MVVM, I bless your kind soul, but take the time to do it RIGHT! Do not use interfaces for one. Let your View decide how it's going to look based on values. Play with the View with Mock data. If you end up having a View that is showing you a Menu (as per the example) even though you didn't want it at the time then GOOD. You're view is working as it should and reacting based on the values as it should. Just add a few more requirements to your trigger to make sure this doesn't happen when the ViewModel is in a particular translated state or command the ViewModel to empty this state. In your ViewModel DO NOT remove this with internal logic either as if you're deciding from there whether or not the View should see it. Remember you can't assume there is a menu or not in the ViewModel. And finally, the Model should just allow you to change and most likely store state. This is where validation and all will occur; for example, if the Model can't modify the state then it will simply flag itself as dirty or something. When the ViewModel realizes this it will translate what's dirty, and the View will then realize this and show some information via another trigger. All data in the View can be binded to the ViewModel so everything can be dynamic only the Model and ViewModel has absolutely no idea about how the View will react to the binding. As a matter of fact the Model has no idea of a ViewModel either. When setting up dependencies they should point like so and only like so View ? ViewModel ? Model (and a side note here... and this will probably get argued as well but I don't care... DO NOT PASS THE MODEL to the VIEW unless that MODEL is immutable; otherwise wrap it with a proper ViewModel. The View should not see a model period. I give a rats crack what demo you've seen or how you've done it, that's wrong.)

Here's my final tip... Look at a well designed, yet very simple, MVC application and do the same for an MVVM application. One will have more control with limited to zero flexibility while the other will have no control and unlimited flexibility.

A controlled environment is good for managing the entire application from a set of controllers or (a single source) while a reactive environment can be broken up into separate repositories with absolutely no idea of what the rest of the application is doing. Micro managing vs free management.

If I haven't confused you enough try contacting me... I don't mind going over this in full detail with illustration and examples.

At the end of the day we're all programmers and with that anarchy lives within us when coding... So rules will be broken, theories will change, and all of this will end up hog wash... But when working on large projects and on large teams, it really helps to agree on a design pattern and enforce it. One day it will make the small extra steps taken in the beginning become leaps and bounds of savings later.

>>> my_list = ['this\n', 'is\n', 'a\n', 'list\n', 'of\n', 'words\n']
>>> map(str.strip, my_list)
['this', 'is', 'a', 'list', 'of', 'words']

The alternate way, that doesn't require RPMs. You need to be root.

1. Dependencies

   Install the following packages:

   apt-get install python-dev build-essential libaio1
   

2. Download Instant Client for Linux x86-64

   Download the following files from Oracle's download site:

   

3. Extract the zip files

   Unzip the downloaded zip files to some directory, I'm using:

   /opt/ora/
   

4. Add environment variables

   Create a file in /etc/profile.d/oracle.sh that includes

   export ORACLE_HOME=/opt/ora/instantclient_11_2
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
   

   Create a file in /etc/ld.so.conf.d/oracle.conf that includes

   /opt/ora/instantclient_11_2
   

   Execute the following command

   sudo ldconfig
   

   Note: you may need to reboot to apply settings

5. Create a symlink

   cd $ORACLE_HOME 
   ln -s libclntsh.so.11.1 libclntsh.so
   

6. Install cx_Oracle python package

   • You may install using pip

     pip install cx_Oracle
     

   • Or install manually

     Download the cx_Oracle source zip that corresponds with your Python and Oracle version. Then expand the archive, and run from the extracted directory:

     python setup.py build 
     python setup.py install
     

If you put the SQL strings in a properties file and then read that in you can keep the SQL strings in a plain text file.

That doesn't solve the SQL type issues, but at least it makes copying&pasting from TOAD or sqlplus much easier.

I found an easy way to make my back button with iOS single arrow.

Let's supouse that you have a navigation controller going to ViewA from ViewB. In IB, select ViewA's navigation bar, you should see these options: Title, Prompt and Back Button.

ViewA navigate bar options

The trick is choose your destiny view controller back button title (ViewB) in the options of previous view controller (View A). If you don't fill the option "Back Button", iOS will put the title "Back" automatically, with previous view controller's title. So, you need to fill this option with a single space.

Fill space in "Back Button" option

The Result:

Late to the show here, BUT, I was able to add a fill color to the SVG polygon, if you're able to directly edit the SVG code, so for example the following svg renders red, instead of default black. I have not tested outside of Chrome though:

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
 width="500px" height="500px" viewBox="0 0 500 500" enable-background="new 0 0 500 500" xml:space="preserve">
    <polygon 


        fill="red"


        fill-rule="evenodd" clip-rule="evenodd" points="452.5,233.85 452.5,264.55 110.15,264.2 250.05,390.3 229.3,413.35 
47.5,250.7 229.3,86.7 250.05,109.75 112.5,233.5 "/>
</svg>

It means not equal to, this is a good method to exclude certain elements from your query. For example lets say you have an orders tables and then you have OrderStatusID column within that table.

You also have a status table where

0 = OnHold, 
1 = Processing, 
2 = WaitingPayment, 
3 = Shipped, 
4 = Canceled.

You can run a query where

Select * From [Orders] where OrderStatusID <> 4

this should give you all the orders except those that have been canceled! :D

The way to do this is via the bracket notation.

var test = {_x000D_
    "id": "109",_x000D_
    "No. of interfaces": "4"_x000D_
}_x000D_
alert(test["No. of interfaces"]);

This could help:

public static String getCorporateID(String fileName) {

    String corporateId = null;

    try {
        corporateId = fileName.substring(0, fileName.indexOf("_"));
        // System.out.println(new Date() + ": " + "Corporate:
        // "+corporateId);
        return corporateId;
    } catch (Exception e) {
        corporateId = null;
        e.printStackTrace();
    }

    return corporateId;
}

If you are dealing with more dynamic screen resolution/sizes, instead of hardcoding the size in pixels you can change the width to a percentage of the media width as such

@media (min-width: 1200px) {
    .container{
        max-width: 70%;
   }
}

wget -r -np -nH --cut-dirs=3 -R index.html http://hostname/aaa/bbb/ccc/ddd/

From man wget

‘-r’ ‘--recursive’ Turn on recursive retrieving. See Recursive Download, for more details. The default maximum depth is 5.

‘-np’ ‘--no-parent’ Do not ever ascend to the parent directory when retrieving recursively. This is a useful option, since it guarantees that only the files below a certain hierarchy will be downloaded. See Directory-Based Limits, for more details.

‘-nH’ ‘--no-host-directories’ Disable generation of host-prefixed directories. By default, invoking Wget with ‘-r http://fly.srk.fer.hr/’ will create a structure of directories beginning with fly.srk.fer.hr/. This option disables such behavior.

‘--cut-dirs=number’ Ignore number directory components. This is useful for getting a fine-grained control over the directory where recursive retrieval will be saved.

Take, for example, the directory at ‘ftp://ftp.xemacs.org/pub/xemacs/’. If you retrieve it with ‘-r’, it will be saved locally under ftp.xemacs.org/pub/xemacs/. While the ‘-nH’ option can remove the ftp.xemacs.org/ part, you are still stuck with pub/xemacs. This is where ‘--cut-dirs’ comes in handy; it makes Wget not “see” number remote directory components. Here are several examples of how ‘--cut-dirs’ option works.

No options -> ftp.xemacs.org/pub/xemacs/ -nH -> pub/xemacs/ -nH --cut-dirs=1 -> xemacs/ -nH --cut-dirs=2 -> .

--cut-dirs=1 -> ftp.xemacs.org/xemacs/ ... If you just want to get rid of the directory structure, this option is similar to a combination of ‘-nd’ and ‘-P’. However, unlike ‘-nd’, ‘--cut-dirs’ does not lose with subdirectories—for instance, with ‘-nH --cut-dirs=1’, a beta/ subdirectory will be placed to xemacs/beta, as one would expect.

You shall pass a this pointer to tell the function which object to work on because it relies on that as opposed to a static member function.

Simply add this event to your text field. It will prevent a submission on pressing Enter, and you're free to add a submit button or call form.submit() as required:

onKeyPress="if (event.which == 13) return false;"

For example:

<input id="txt" type="text" onKeyPress="if (event.which == 13) return false;"></input>

You can use .find():

map<string,string>::iterator i = m.find("f");

if (i == m.end()) { /* Not found */ }
else { /* Found, i->first is f, i->second is ++-- */ }

You can increase the timeout in node like so.

app.post('/slow/request', function(req, res){ req.connection.setTimeout(100000); //100 seconds ... }

It is very important to notice that, as of HTML5, <wbr> and ­ are not supposed to do the same thing!

Soft hyphens

­ is a soft hyphen, i.e., U+00AD: SOFT HYPHEN. For example,

innehålls­förteckning

might be rendered as

innehållsförteckning

or as

innehålls-
förteckning

As of today, soft hyphens work in Firefox, Chrome, and Internet Explorer.

The wbr element

The wbr element is a word-break opportunity, which will not display a hyphen if a line break occurs. For example,

ABCDEFG<wbr/>abcdefg

might be rendered as

ABCDEFGabcdefg

or as

ABCDEFG
abcdefg

As of today, this element works in Firefox and Chrome.

Here is a non-numpy solution:

>>> a = [[40, 10], [50, 11]]
>>> [float(sum(l))/len(l) for l in zip(*a)]
[45.0, 10.5]

Here's a controller

@RestController
@RequestMapping("/loggers")
public class LoggerConfigController {

private final static org.slf4j.Logger LOGGER = LoggerFactory.getLogger(PetController.class);

@GetMapping()

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

Sources: http://docs.oracle.com/javase/6/docs/api/java/net/URL.html

Let a be a string and b the string you look for. Use a.substr to get the last n characters of a and compare them to b (where n is the length of b)

Or use std::equal (include <algorithm>)

Ex:

bool EndsWith(const string& a, const string& b) {
    if (b.size() > a.size()) return false;
    return std::equal(a.begin() + a.size() - b.size(), a.end(), b.begin());
}

It sounds like you have macro recording turned on. To shut it off, press q.

You can do something like this.

 List<Map<String, Object>> mapList = jdbctemplate.queryForList(query));
    return mapList.stream().collect(Collectors.toMap(k -> (Long) k.get("userid"), k -> (String) k.get("username")));

Output:

 {
  1: "abc",
  2: "def",
  3: "ghi"
}

Just pass the object reference to the following function and you will get the index

function thisindex(elm) 
{ 
    var the_li = elm; 
    var the_ul = elm.parentNode; 
    var li_list = the_ul.childNodes; 

    var count = 0; // Tracks the index of LI nodes

    // Step through all the child nodes of the UL
    for( var i = 0; i < li_list.length; i++ )
    {
        var node = li_list.item(i);
        if( node )
        {
        // Check to see if the node is a LI
            if( node.nodeName == "LI" )
            {
            // Increment the count of LI nodes
                count++;
            // Check to see if this node is the one passed in
                if( the_li == node )
                {
                    // If so, alert the current count
                    alert(count-1);
                }
            }
        }
    }
}

This should do the trick:

<table width="400" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="50" height="40" valign="top" rowspan="3">
      <img alt="" src="" width="40" height="40" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
    <td width="350" height="40" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<a href="" style="color: #D31145; font-weight: bold; text-decoration: none;">LAST FIRST</a><br>

    </td>
  </tr>
  <tr>
    <td width="350" height="70" valign="bottom" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<img alt="" src="" width="200" height="60" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
  </tr>
  <tr>
    <td width="350" height="20" valign="bottom" style="font-family: Helvetica, Arial, sans-serif; font-size: 10px; color: #000000;">
all your minor text here | all your minor text here | all your minor text here
    </td>
  </tr>
</table>

UPDATE: Adjusted code per the comments:

After viewing your jsFiddle, an important thing to note about tables is that table cell widths in each additional row all have to be the same width as the first, and all cells must add to the total width of your table.

Here is an example that will NOT WORK:

<table width="600" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="200" bgcolor="#252525">&nbsp;
    </td>
    <td width="400" bgcolor="#454545">&nbsp;
    </td>
  </tr>
  <tr>
    <td width="300" bgcolor="#252525">&nbsp;
    </td>
    <td width="300" bgcolor="#454545">&nbsp;
    </td>
  </tr>
</table>

Although the 2nd row does add up to 600, it (and any additional rows) must have the same 200-400 split as the first row, unless you are using colspans. If you use a colspan, you could have one row, but it needs to have the same width as the cells it is spanning, so this works:

<table width="600" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="200" bgcolor="#252525">&nbsp;
    </td>
    <td width="400" bgcolor="#454545">&nbsp;
    </td>
  </tr>
  <tr>
    <td width="600" colspan="2" bgcolor="#353535">&nbsp;
    </td>
  </tr>
</table>

Not a full tutorial, but I hope that helps steer you in the right direction in the future.

Here is the code you are after:

<table width="900" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="57" height="43" valign="top" rowspan="2">
      <img alt="Rashel Adragna" src="http://zoparealtygroup.com/wp-content/uploads/2013/10/sig_head.png" width="47" height="43" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
    <td width="843" height="43" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<a href="" style="color: #D31145; font-weight: bold; text-decoration: none;">RASHEL ADRAGNA</a><br>
REALTOR | P 855.900.24KW
    </td>
  </tr>
  <tr>
    <td width="843" height="64" valign="bottom" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<img alt="Zopa Realty Group logo" src="http://zoparealtygroup.com/wp-content/uploads/2013/10/sig_logo.png" width="177" height="54" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
  </tr>
  <tr>
    <td width="843" colspan="2" height="20" valign="bottom" align="center" style="font-family: Helvetica, Arial, sans-serif; font-size: 10px; color: #000000;">
all your minor text here | all your minor text here | all your minor text here
    </td>
  </tr>
</table>

You'll note that I've added an extra 10px to some of your table cells. This in combination with align/valigns act as padding between your cells. It is a clever way to aviod actually having to add padding, margins or empty padding cells.

First of all, there are still browsers out there that don't support those pseudo-elements (ie. :first-child, :last-child), so you have to 'deal' with this issue.

There is a good example how to make that work without using pseudo-elements:

http://www.darowski.com/tracesofinspiration/2010/01/11/this-newbies-first-impressions-of-haml-and-sass/

       -- see the divider pipe example.

I hope that was useful.

You can import the module and have access through its name if you don't want to mix functions and classes with yours

import util # imports util.py

util.clean()
util.setup(4)

or you can import the functions and classes to your code

from util import clean, setup
clean()
setup(4)

you can use wildchar * to import everything in that module to your code

from util import *
clean()
setup(4)

Your first attempt was close. Here is the simplistic approach using your idea.

file="somefileondisk"
lines=`cat $file`
for line in $lines; do
        echo "$line"
done

There's another solution for it if you are not using native Promises but Bluebird.

You could also try using Promise.map(), mixing the array.map and Promise.all

In you case:

  var arr = [1,2,3,4,5];

  var results: number[] = await Promise.map(arr, async (item): Promise<number> => {
    await callAsynchronousOperation(item);
    return item + 1;
  });

You may actually go with ViewChild API...

• Check your forked plunker for complete code - ViewChild API

parent.ts

<button (click)="clicked()">click</button>

export class App {
  @ViewChild(Child) vc:Child;
  constructor() {
    this.name = 'Angular2'
  }

  func(e) {
    console.log(e)

  }
  clicked(){
   this.vc.getName();
  }
}

child.ts

export class Child implements OnInit{

  onInitialized = new EventEmitter<Child>();
  ...  
  ...
  getName()
  {
     console.log('called by vc')
     console.log(this.name);
  }
}

Pandas dataframe copy warning

When you go and do something like this:

quote_df = quote_df.ix[:,[0,3,2,1,4,5,8,9,30,31]]

pandas.ix in this case returns a new, stand alone dataframe.

Any values you decide to change in this dataframe, will not change the original dataframe.

This is what pandas tries to warn you about.

Why .ix is a bad idea

The .ix object tries to do more than one thing, and for anyone who has read anything about clean code, this is a strong smell.

Given this dataframe:

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

Two behaviors:

dfcopy = df.ix[:,["a"]]
dfcopy.a.ix[0] = 2

Behavior one: dfcopy is now a stand alone dataframe. Changing it will not change df

df.ix[0, "a"] = 3

Behavior two: This changes the original dataframe.

Use .loc instead

The pandas developers recognized that the .ix object was quite smelly[speculatively] and thus created two new objects which helps in the accession and assignment of data. (The other being .iloc)

.loc is faster, because it does not try to create a copy of the data.

.loc is meant to modify your existing dataframe inplace, which is more memory efficient.

.loc is predictable, it has one behavior.

The solution

What you are doing in your code example is loading a big file with lots of columns, then modifying it to be smaller.

The pd.read_csv function can help you out with a lot of this and also make the loading of the file a lot faster.

So instead of doing this

quote_df = pd.read_csv(StringIO(str_of_all), sep=',', names=list('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefg')) #dtype={'A': object, 'B': object, 'C': np.float64}
quote_df.rename(columns={'A':'STK', 'B':'TOpen', 'C':'TPCLOSE', 'D':'TPrice', 'E':'THigh', 'F':'TLow', 'I':'TVol', 'J':'TAmt', 'e':'TDate', 'f':'TTime'}, inplace=True)
quote_df = quote_df.ix[:,[0,3,2,1,4,5,8,9,30,31]]

Do this

columns = ['STK', 'TPrice', 'TPCLOSE', 'TOpen', 'THigh', 'TLow', 'TVol', 'TAmt', 'TDate', 'TTime']
df = pd.read_csv(StringIO(str_of_all), sep=',', usecols=[0,3,2,1,4,5,8,9,30,31])
df.columns = columns

This will only read the columns you are interested in, and name them properly. No need for using the evil .ix object to do magical stuff.

You don't need regex to split a string on whitespace:

In [1]: text = '''WYATT    - Ranked # 855 with    0.006   %
   ...: XAVIER   - Ranked # 587 with    0.013   %
   ...: YONG     - Ranked # 921 with    0.006   %
   ...: YOUNG    - Ranked # 807 with    0.007   %'''

In [2]: print '\n'.join(line.split()[0] for line in text.split('\n'))
WYATT
XAVIER
YONG
YOUNG

This works for me. I'm sorry if I cannot remember the source. It is probably from a man page.

#include <ftw.h>

int AnalizeDirectoryElement (const char *fpath, 
                            const struct stat *sb,
                            int tflag, 
                            struct FTW *ftwbuf) {

  if (tflag == FTW_F) {
    std::string strFileName(fpath);

    DoSomethingWith(strFileName);
  }
  return 0; 
}

void WalkDirectoryTree (const char * pchFileName) {

  int nFlags = 0;

  if (nftw(pchFileName, AnalizeDirectoryElement, 20, nFlags) == -1) {
    perror("nftw");
  }
}

int main() {
  WalkDirectoryTree("some_dir/");
}

Do keep in mind that the file.getContentType could also output application/octet-stream instead of the required application/vnd.openxmlformats-officedocument.spreadsheetml.sheet when you try to upload the file that is already open.

In order to execute multiple programs, I also needed a profiles section:

<profiles>
  <profile>
    <id>traverse</id>
    <activation>
      <property>
        <name>traverse</name>
      </property>
    </activation>
    <build>
      <plugins>
        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <configuration>
            <executable>java</executable>
            <arguments>
              <argument>-classpath</argument>
              <argument>org.dhappy.test.NeoTraverse</argument>
            </arguments>
          </configuration>
        </plugin>
      </plugins>
    </build>
  </profile>
</profiles>

This is then executable as:

mvn exec:exec -Ptraverse

When you create a String, you can think of it as a list of char's, this means that for each character in your String, you need to support all the possible values of char. From the sun docs

char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive).

If you have a reduced set of characters you want to support you can write a simple compression algorithm, which is analogous to binary->decimal->hex radix converstion. You go from 65,536 (or however many characters your target system supports) to 26 (alphabetical) / 36 (alphanumeric) etc.

I've used this trick a few times, for example encoding timestamps as text (target 36 +, source 10) - just make sure you have plenty of unit tests!

Extending adam-rosenfield's solution, i think the following will work for multithreaded single producer - single consumer scenario.

int cb_push_back(circular_buffer *cb, const void *item)
{
  void *new_head = (char *)cb->head + cb->sz;
  if (new_head == cb>buffer_end) {
      new_head = cb->buffer;
  }
  if (new_head == cb->tail) {
    return 1;
  }
  memcpy(cb->head, item, cb->sz);
  cb->head = new_head;
  return 0;
}

int cb_pop_front(circular_buffer *cb, void *item)
{
  void *new_tail = cb->tail + cb->sz;
  if (cb->head == cb->tail) {
    return 1;
  }
  memcpy(item, cb->tail, cb->sz);
  if (new_tail == cb->buffer_end) {
    new_tail = cb->buffer;
  }
  cb->tail = new_tail;
  return 0;
}

In sproc, you can use the following condition:

DECLARE @USER_ID VARCAHR(15)=NULL --THIS VALUE IS NULL OR EMPTY DON'T MATTER
IF(COALESCE(@USER_ID,'')='')
PRINT 'HUSSAM'

I had the same problem and I could solve it by adding the entity into persistence.xml. The problem was caused due to the fact that the entity was not added to the persistence config. Edit your persistence file:

<persistence-unit name="MY_PU" transaction-type="RESOURCE_LOCAL">
<provider>`enter code here`
     org.hibernate.jpa.HibernatePersistenceProvider
  </provider>
<class>mypackage.MyEntity</class>

Might want to check out jQuery Timer to manage one or multiple timers.

http://code.google.com/p/jquery-timer/

var timer = $.timer(yourfunction, 10000);

function yourfunction() { alert('test'); }

Then you can control it with:

timer.play();
timer.pause();
timer.toggle();
timer.once();
etc...

You should be able to just look at .Keys:

    Dictionary<string, int> data = new Dictionary<string, int>();
    data.Add("abc", 123);
    data.Add("def", 456);
    foreach (string key in data.Keys)
    {
        Console.WriteLine(key);
    }

private void selectDOB() {

    final Calendar calendar = Calendar.getInstance();
    mYear = calendar.get(Calendar.YEAR);
    mDay = calendar.get(Calendar.DATE);
    mMonth = calendar.get(Calendar.MONTH);

    DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
        @SuppressLint("LongLogTag")
        @Override
        public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
            strDateOfBirth = (month + 1) + "-" + dayOfMonth + "-" + year;

            //********************** check and set date with append 0 at starting***************************
            if (dayOfMonth < 10) {
                strNewDay = "0" + dayOfMonth;
            } else {
                strNewDay = dayOfMonth + "";
            }
            if (month + 1 < 10) {
                strNewMonth = "0" + (month + 1);
            } else {
                strNewMonth = (month + 1) + "";
            }

            Log.e("strnewDay *****************", strNewDay + "");
            Log.e("strNewMonth *****************", strNewMonth + "");

            //    etDateOfBirth.setText(dayOfMonth + " / " + (month + 1) + " / " + year);
            etDateOfBirth.setText(strNewDay + " / " + strNewMonth + " / " + year);

            Log.e("strDateOfBirth *******************", strDateOfBirth + "");

        }
    }, mYear, mMonth, mDay);

    datePickerDialog.show();

    //*************** input date of birth must be greater than or equal to 18 ************************************

    Calendar maxDate = Calendar.getInstance();
    maxDate.set(Calendar.DAY_OF_MONTH, mDay);
    maxDate.set(Calendar.MONTH, mMonth);
    maxDate.set(Calendar.YEAR, mYear - 18);
    datePickerDialog.getDatePicker().setMaxDate(maxDate.getTimeInMillis());

    //*************** input date of birth must be less than today date ************************************
    //   datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());

}

Your mistake is looking for range, which gives you the range of a vector, for example:

range(c(10, -5, 100))

gives

 -5 100

Instead, look at the : operator to give sequences (with a step size of one):

1:100

or you can use the seq function to have a bit more control. For example,

##Step size of 2
seq(1, 100, by=2)

or

##length.out: desired length of the sequence
seq(1, 100, length.out=5)

You are more vulnerable to attacks if using eval: JSON is a subset of Javascript and json.parse just parses JSON whereas eval would leave the door open to all JS expressions.

I'm not sure if you can make a TextBlock selectable, but another option would be to use a RichTextBox - it is like a TextBox as you suggested, but supports the formatting you want.

I had a similar issue with Intellij. The issue was that someone added the file that I am trying to compare in Intellij to .gitignore, without actually deleting the file from Git.

I also encountered this by injecting service A into service B and vice versa.

I think it's a good thing that this fails fast as it should probably be avoided anyway. If you want your services to be more modular and re-usable, it's best to avoid circular references as much as possible. This post highlights the pitfalls surrounding that.

Therefore, I have the following recommendations:

• If you feel the classes are interacting too often (I'm talking about feature envy), you might want to consider merging the 2 services into 1 class.
• If the above doesn't work for you, consider using a 3rd service, (an EventService) which both services can inject in order to exchange messages.

SQL Server returns messages after a batch of statements has been executed. Normally, you'd use SQL GO to indicate the end of a batch and to retrieve the results:

PRINT '1'
GO

WAITFOR DELAY '00:00:05'

PRINT '2'
GO

WAITFOR DELAY '00:00:05'

PRINT '3'
GO

In this case, however, the print statement you want returned immediately is in the middle of a loop, so the print statements cannot be in their own batch. The only command I know of that will return in the middle of a batch is RAISERROR (...) WITH NOWAIT, which gbn has provided as an answer as I type this.

Below code will do the job if anyone wants to load a custom View with XIB Programmatically.

let customView = UINib(nibName:"CustomView",bundle:.main).instantiate(withOwner: nil, options: nil).first as! UIView
customView.frame = self.view.bounds
self.view.addSubview(customView)

First page (scroll down to see the second page)_x000D_
<div style="break-after:page"></div>_x000D_
Second page_x000D_
<br>_x000D_
<br>_x000D_
<button onclick="window.print();return false;" />Print (to see the result) </button>

Just add this where you need the page to go to the next one (the text "page 1" will be on page 1 and the text "page 2" will be on the second page).

Page 1
<div style='page-break-after:always'></div>
Page 2

This works too:

First page (there is a break after this)
<div style="break-after:page"></div>
Second page (This will be printed in the second page)

I had the exact same problem (.NET Core 2.0.1).

Sometimes it helps if the project is rebuilt.

I also encounter the problem when I opened the project in 2 Visual Studios.
Closing one Visual Studio fixed the error.

To only get those errors that cause the application to stop working, use:

error_reporting(E_ALL ^ (E_NOTICE | E_WARNING | E_DEPRECATED));

This will stop showing notices, warnings, and deprecated errors.

Here is all command lines to install magento2

PHP Extension xsl and intl. CMD

sudo apt-get install php5-intl
sudo apt-get install php5-xsl
sudo php5enmod xsl
sudo service apache2 restart

PHP Extension mcrypt. CMD

sudo updatedb 
locate mcrypt.ini
sudo php5enmod mcrypt

Besides aws_access_key_id and aws_secret_access_key, I also added aws_session_token in credentials, it works for me

The default timeout is 900 second. You can specify different timeout.

-T seconds
--timeout=seconds

The default is to retry 20 times. You can specify different tries.

-t number
--tries=number

link: wget man document

Work example to find average default center with react-google-maps on ES6:

const bounds = new google.maps.LatLngBounds();
paths.map((latLng) => bounds.extend(new google.maps.LatLng(latLng)));
const defaultCenter = bounds.getCenter();
<GoogleMap
 defaultZoom={paths.length ? 12 : 4}
 defaultCenter={defaultCenter}
>
 <Marker position={{ lat, lng }} />
</GoogleMap>

I had a similar problem due to the fact that I forgot to show the render parameter

<script src='https://www.google.com/recaptcha/api.js?render=SITE_KEY' async defer></script>

I beleive

$("#myElement").attr("title", "new title value")

or

$("#myElement").prop("title", "new title value")

should do the trick...

I think you can find all the core functions in the jQuery Docs, although I hate the formatting.

enter code here

clrs = np.linspace( 0, 1, 18 )  # It will generate 
# color only for 18 for more change the number
np.random.shuffle(clrs)
colors = []
for i in range(0, 72, 4):
    idx = np.arange( 0, 18, 1 )
    np.random.shuffle(idx)
    r = clrs[idx[0]]
    g = clrs[idx[1]]
    b = clrs[idx[2]]
    a = clrs[idx[3]]
    colors.append([r, g, b, a])

If you need to perform in Microsoft Windows the equivalent of a symlink to /dev/null in Linux you would open and administrator's cmd and type:

For files:

mklink c:\path\to\file.ext NUL:

Or, for directories:

mklink /D c:\path\to\dir NUL:

This will keep the file/direcotry always at 0 byte, and still return success to every write attempt.

if you are using localhost database, try port 3306

Open eclipse and right click in the package explorer ? import Select gradle Browse to the location where you checked out Click “Build Model” Select all the projects and hit finish

There is also a plugin to jquery to determine element location and offsets

http://plugins.jquery.com/project/dimensions

scrolling offset = offsetHeight property of an element

ls -l --block-size=M 

will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB. If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.

Or

ls -lah 

-h When used with the -l option, use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number of digits to three or less using base 2 for sizes.

1. match_parent

When you set layout width and height as match_parent, it will occupy the complete area that the parent view has, i.e. it will be as big as the parent.

Note : If parent is applied a padding then that space would not be included.

When we create a layout.xml by default we have RelativeLayout as default parent View with android:layout_width="match_parent" and android:layout_height="match_parent" i.e it occupies the complete width and height of the mobile screen.

Also note that padding is applied to all sides,

android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

Now lets add a sub-view LinearLayout and sets its layout_width="match_parent" and layout_height="match_parent", the graphical view would display something like this,

match_parent_example

Code

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.code2care.android.togglebuttonexample.MainActivity" >

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="11dp"
android:background="#FFFFEE"
android:orientation="vertical" >

2. fill_parent :

This is same as match_parent, fill_parent was depreciated in API level 8. So if you are using API level 8 or above you must avoid using fill_parent

Lets follow the same steps as we did for match_parent, just instead use fill_parent everywhere.

You would see that there is no difference in behaviour in both fill_parent and match parent.

If choosing between OAuth versions, go with OAuth 2.0.

OAuth bearer tokens should only be used with a secure transport.

OAuth bearer tokens are only as secure or insecure as the transport that encrypts the conversation. HTTPS takes care of protecting against replay attacks, so it isn't necessary for the bearer token to also guard against replay.

While it is true that if someone intercepts your bearer token they can impersonate you when calling the API, there are plenty of ways to mitigate that risk. If you give your tokens a long expiration period and expect your clients to store the tokens locally, you have a greater risk of tokens being intercepted and misused than if you give your tokens a short expiration, require clients to acquire new tokens for every session, and advise clients not to persist tokens.

If you need to secure payloads that pass through multiple participants, then you need something more than HTTPS/SSL, since HTTPS/SSL only encrypts one link of the graph. This is not a fault of OAuth.

Bearer tokens are easy to for clients to obtain, easy for clients to use for API calls and are widely used (with HTTPS) to secure public facing APIs from Google, Facebook, and many other services.

This problem happened with me and sovled by just add

Using numpy, you can do:

y = x.astype(int)

If you were using a non-numpy array, you could use a list comprehension:

y = [int(val) for val in x]

I would consider activity to be whether or not the user is focused on the window. For example, when you click from one window to another (e.g. Google Chrome to iTunes, or Tab 1 to Tab 2 within an internet browser), the webpage can send a callback saying "Im out of focus!" or "Im in focus!". One could use jQuery to harness this possible lack of activity to do whatever they wanted. If I were in your position, I would use the following code to check for focus every 5 seconds, etc and reload if no focus.

var window_focus;
$(window).focus(function() {
    window_focus = true;
}).blur(function() {
    window_focus = false;
});
function checkReload(){
    if(!window_focus){
        location.reload();  // if not focused, reload
    }
}
setInterval(checkReload, 5000);  // check if not focused, every 5 seconds

Just run this in a console.

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
cinst powershell

It installs the latest version using a Chocolatey repository.

Originally I was using command cinst powershell 3.0.20121027, but it looks like it later stopped working. Since this question is related to PowerShell 3.0 this was the right way. At this moment (June 26, 2014) cinst powershell refers to version 3.0 of PowerShell, and that may change in future.

See the Chocolatey PowerShell package page for details on what version will be installed.

First you need to remember that in Unix and Linux, everything is a file, even directories. For a file to have the rights to be executed as a command, it needs to satisfy 3 conditions:

1. It needs to be a regular file
2. It needs to have read-permissions
3. It needs to have execute-permissions

So this can be done simply with:

[ -f "${file}" ] && [ -r "${file}" ] && [ -x "${file}" ]

If your file is a symbolic link to a regular file, the test command will operate on the target and not the link-name. So the above command distinguishes if a file can be used as a command or not. So there is no need to pass the file first to realpath or readlink or any of those variants.

If the file can be executed on the current OS, that is a different question. Some answers above already pointed to some possibilities for that, so there is no need to repeat it here.

if ( length(a <- which(1:3 == 5) ) ) print(a)  else print("nothing returned for 'a'") 
#[1] "nothing returned for 'a'"

On second thought I think any is more beautiful than length(.):

 if ( any(a <- which(1:3 == 5) ) ) print(a)  else print("nothing returned for 'a'") 
 if ( any(a <- 1:3 == 5 ) ) print(a)  else print("nothing returned for 'a'")

The differences are

1. Only in String class + operator is overloaded. We can concat two String object using + operator, but in the case of StringBuffer we can't.

2. String class is overriding toString(), equals(), hashCode() of Object class, but StringBuffer only overrides toString().

   String s1 = new String("abc");
   String s2 = new String("abc");
   System.out.println(s1.equals(s2));  // output true
   
   StringBuffer sb1 = new StringBuffer("abc");
   StringBuffer sb2 = new StringBuffer("abc");
   System.out.println(sb1.equals(sb2));  // output false
   

3. String class is both Serializable as well as Comparable, but StringBuffer is only Serializable.

   Set<StringBuffer> set = new TreeSet<StringBuffer>();
   set.add(sb1);
   set.add(sb2);
   System.out.println(set);  // gives ClassCastException because there is no Comparison mechanism
   

4. We can create a String object with and without new operator, but StringBuffer object can only be created using new operator.

5. String is immutable but StringBuffer is mutable.
6. StringBuffer is synchronized, whereas String ain't.
7. StringBuffer is having an in-built reverse() method, but String dosen't have it.

I set up Visual Studio Code as a default to open .txt file. And next I did use simple command: git config --global core.editor "'C:\Users\UserName\AppData\Local\Code\app-0.7.10\Code.exe\'". And everything works pretty well.

Change your append calls to say

...append(iter->first)

and

... append(iter->second)

Additionally, the line

std::string* strToReturn = new std::string("");

allocates a string on the heap. If you intend to actually return a pointer to this dynamically allocated string, the return should be changed to std::string*.

Alternatively, if you don't want to worry about managing that object on the heap, change the local declaration to

std::string strToReturn("");

and change the 'append' calls to use reference syntax...

strToReturn.append(...)

instead of

strToReturn->append(...)

Be aware that this will construct the string on the stack, then copy it into the return variable. This has performance implications.

For checking existence one can also use (works for both, files and folders):

Not Dir(DirFile, vbDirectory) = vbNullString

_{The result is True if a file or a directory exists.}

Example:

If Not Dir("C:\Temp\test.xlsx", vbDirectory) = vbNullString Then
    MsgBox "exists"
Else
    MsgBox "does not exist"
End If

Check this:

HTML:

<select id="test" multiple>
<option value="red" selected>Red</option>
<option value="rock" selected>Rock</option>
<option value="sun">Sun</option>
</select>

Javascript one line code

Array.from(document.getElementById("test").options).filter(option => option.selected).map(option => option.value);

The compiler declares the variable in a way that makes it highly prone to an error that is often difficult to find and debug, while producing no perceivable benefits.

Your criticism is entirely justified.

I discuss this problem in detail here:

Closing over the loop variable considered harmful

Is there something you can do with foreach loops this way that you couldn't if they were compiled with an inner-scoped variable? or is this just an arbitrary choice that was made before anonymous methods and lambda expressions were available or common, and which hasn't been revised since then?

The latter. The C# 1.0 specification actually did not say whether the loop variable was inside or outside the loop body, as it made no observable difference. When closure semantics were introduced in C# 2.0, the choice was made to put the loop variable outside the loop, consistent with the "for" loop.

I think it is fair to say that all regret that decision. This is one of the worst "gotchas" in C#, and we are going to take the breaking change to fix it. In C# 5 the foreach loop variable will be logically inside the body of the loop, and therefore closures will get a fresh copy every time.

The for loop will not be changed, and the change will not be "back ported" to previous versions of C#. You should therefore continue to be careful when using this idiom.

if the last element type is article too, last-of-type will not work as expected.

maybe i not really understand how it work.

demo

 def hi():
     bye = 5
     return bye  

print hi()

Well ya you can do that in this way.

    <input type="text" name="address" id="address">
        <div id="map_canvas" style="width: 500px; height: 300px"></div>
    <input type="button" onclick="showAddress(address.value)" value="ShowMap"/>

Java Script

function showAddress(address){

    alert("This is address :"+address)

}

That is one example for the same. and that will run.

Using parameter --force:

npm i -f

If you are trying to get an index based on a predicate, try this:

If you only care about the first index:

OptionalInt index = IntStream.range(0, list.size())
    .filter(i -> list.get(i) == 3)
    .findFirst();

Or if you want to find multiple indexes:

IntStream.range(0, list.size())
   .filter(i -> list.get(i) == 3)
   .collect(Collectors.toList());

Add .orElse(-1); in case you want to return a value if it doesn't find it.

I have followed the best answer of Loktar and it worked very well. The only problem I had was with Chrome (my current version is 27.0.1453.94 m). The problem I had was that it seems Chrome is aware that the text in the link is not visible and it puts the link a little bit lower then it is supposed to be (something like margin-top, but it is not possible to change it). This happens with all the ways in which we make the text invisible: - line-height: 0; - font-size: 0; - text-indent:-9999px;

I was able to fix this problem by adjusting the vertical-align of the link like this:

vertical-align: 25px;

I hope this is helpful

What are raw types in Java, and why do I often hear that they shouldn't be used in new code?

Raw-types are ancient history of the Java language. In the beginning there were Collections and they held Objects nothing more and nothing less. Every operation on Collections required casts from Object to the desired type.

List aList = new ArrayList();
String s = "Hello World!";
aList.add(s);
String c = (String)aList.get(0);

While this worked most of the time, errors did happen

List aNumberList = new ArrayList();
String one = "1";//Number one
aNumberList.add(one);
Integer iOne = (Integer)aNumberList.get(0);//Insert ClassCastException here

The old typeless collections could not enforce type-safety so the programmer had to remember what he stored within a collection.
Generics where invented to get around this limitation, the developer would declare the stored type once and the compiler would do it instead.

List<String> aNumberList = new ArrayList<String>();
aNumberList.add("one");
Integer iOne = aNumberList.get(0);//Compile time error
String sOne = aNumberList.get(0);//works fine

For Comparison:

// Old style collections now known as raw types
List aList = new ArrayList(); //Could contain anything
// New style collections with Generics
List<String> aList = new ArrayList<String>(); //Contains only Strings

More complex the Compareable interface:

//raw, not type save can compare with Other classes
class MyCompareAble implements CompareAble
{
   int id;
   public int compareTo(Object other)
   {return this.id - ((MyCompareAble)other).id;}
}
//Generic
class MyCompareAble implements CompareAble<MyCompareAble>
{
   int id;
   public int compareTo(MyCompareAble other)
   {return this.id - other.id;}
}

Note that it is impossible to implement the CompareAble interface with compareTo(MyCompareAble) with raw types. Why you should not use them:

• Any Object stored in a Collection has to be cast before it can be used
• Using generics enables compile time checks
• Using raw types is the same as storing each value as Object

What the compiler does: Generics are backward compatible, they use the same java classes as the raw types do. The magic happens mostly at compile time.

List<String> someStrings = new ArrayList<String>();
someStrings.add("one");
String one = someStrings.get(0);

Will be compiled as:

List someStrings = new ArrayList();
someStrings.add("one"); 
String one = (String)someStrings.get(0);

This is the same code you would write if you used the raw types directly. Thought I'm not sure what happens with the CompareAble interface, I guess that it creates two compareTo functions, one taking a MyCompareAble and the other taking an Object and passing it to the first after casting it.

What are the alternatives to raw types: Use generics

Although the accepted solution is correct for iPhones, it will incorrectly declare both isiPhone and isiPad to be true for users visiting your site on their iPad from the Facebook app.

The conventional wisdom is that iOS devices have a user agent for Safari and a user agent for the UIWebView. This assumption is incorrect as iOS apps can and do customize their user agent. The main offender here is Facebook.

Compare these user agent strings from iOS devices:

# iOS Safari
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B176 Safari/7534.48.3
iPhone: Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3

# UIWebView
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/98176
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Mobile/8B117

# Facebook UIWebView
iPad: Mozilla/5.0 (iPad; U; CPU iPhone OS 5_1_1 like Mac OS X; en_US) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1.1;FBBV/4110.0;FBDV/iPad2,1;FBMD/iPad;FBSN/iPhone OS;FBSV/5.1.1;FBSS/1; FBCR/;FBID/tablet;FBLC/en_US;FBSF/1.0]
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 5_1_1 like Mac OS X; ru_RU) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1;FBBV/4100.0;FBDV/iPhone3,1;FBMD/iPhone;FBSN/iPhone OS;FBSV/5.1.1;FBSS/2; tablet;FBLC/en_US]

Note that on the iPad, the Facebook UIWebView's user agent string includes 'iPhone'.

The old way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);

If you were to go with this approach for detecting iPhone and iPad, you would end up with IS_IPHONE and IS_IPAD both being true if a user comes from Facebook on an iPad. That could create some odd behavior!

The correct way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = (navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);
if (IS_IPAD) {
  IS_IPHONE = false;
}

We declare IS_IPHONE to be false on iPads to cover for the bizarre Facebook UIWebView iPad user agent. This is one example of how user agent sniffing is unreliable. The more iOS apps that customize their user agent, the more issues user agent sniffing will have. If you can avoid user agent sniffing (hint: CSS Media Queries), DO IT.

Both codes are only relevant when the phone runs out of memory and kills the service before it finishes executing. START_STICKY tells the OS to recreate the service after it has enough memory and call onStartCommand() again with a null intent. START_NOT_STICKY tells the OS to not bother recreating the service again. There is also a third code START_REDELIVER_INTENT that tells the OS to recreate the service and redeliver the same intent to onStartCommand().

This article by Dianne Hackborn explained the background of this a lot better than the official documentation.

Source: http://android-developers.blogspot.com.au/2010/02/service-api-changes-starting-with.html

The key part here is a new result code returned by the function, telling the system what it should do with the service if its process is killed while it is running:

START_STICKY is basically the same as the previous behavior, where the service is left "started" and will later be restarted by the system. The only difference from previous versions of the platform is that it if it gets restarted because its process is killed, onStartCommand() will be called on the next instance of the service with a null Intent instead of not being called at all. Services that use this mode should always check for this case and deal with it appropriately.

START_NOT_STICKY says that, after returning from onStartCreated(), if the process is killed with no remaining start commands to deliver, then the service will be stopped instead of restarted. This makes a lot more sense for services that are intended to only run while executing commands sent to them. For example, a service may be started every 15 minutes from an alarm to poll some network state. If it gets killed while doing that work, it would be best to just let it be stopped and get started the next time the alarm fires.

START_REDELIVER_INTENT is like START_NOT_STICKY, except if the service's process is killed before it calls stopSelf() for a given intent, that intent will be re-delivered to it until it completes (unless after some number of more tries it still can't complete, at which point the system gives up). This is useful for services that are receiving commands of work to do, and want to make sure they do eventually complete the work for each command sent.

I had the problem, that the classpath was broken somehow.

So right click on the project in Package explorer > Plug-in tools > Update classpath... did it for me

Not the newest thread but i searched for a solution for the same Problem and found one (a mix of some others).

I gave the NavButton:

<type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"> ...

an id / Identifier like:

 <button id="navcop" type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">

Not the finest "Idea" - but: Works for me! Now you can check up the visibility of your button (with jquery) like:

 var target = $('#navcop');
   if(target.is(":visible")){
   $('#navcop').click();
   }

(NOTE: This is just a Code snipped ! I used a "onclick" Event on my Nav Links! (Starting a AJAX Reguest.)

The result is: If the Button is "visible" it got "clicked" ... So: No Bug if you use the "Fullscreen view" of Bootstrap (width of over 940px).

Greetings Ralph

PS: It works fine with IE9, IE10 and Firefox 25. Didnt checked up others - But i can't see a Problem :-)

You can find all sorts of professional code with 'break' statements in them. It perfectly make sense to use this whenever necessary. In your case this option is better than creating a separate variable just for the purpose of coming out of the loop.

using angularjs:

$timeout(function(){
if(yourvariable===-1){
doSomeThingAfter5Seconds();
}
},5000)

Unbelievably, in 2019 with Android studio 3.3 (I don't know exact version, at least 3.3), it is possible to use double slash comment to xml.

But if you use double slash comment in xml, IDE shows warning.

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

    // this works

    /* this works too */

    /*
    multi line comment
    multi line comment
    */

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World! yeah"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

If you are on SQL Server 2008 you can also use

 CRYPT_GEN_RANDOM(2) % 10000

Which seems somewhat simpler (it is also evaluated once per row as newid is - shown below)

DECLARE @foo TABLE (col1 FLOAT)

INSERT INTO @foo SELECT 1 UNION SELECT 2

UPDATE @foo
SET col1 =  CRYPT_GEN_RANDOM(2) % 10000

SELECT *  FROM @foo

Returns (2 random probably different numbers)

col1
----------------------
9693
8573

Mulling the unexplained downvote the only legitimate reason I can think of is that because the random number generated is between 0-65535 which is not evenly divisible by 10,000 some numbers will be slightly over represented. A way around this would be to wrap it in a scalar UDF that throws away any number over 60,000 and calls itself recursively to get a replacement number.

CREATE FUNCTION dbo.RandomNumber()
RETURNS INT
AS
  BEGIN
      DECLARE @Result INT

      SET @Result = CRYPT_GEN_RANDOM(2)

      RETURN CASE
               WHEN @Result < 60000
                     OR @@NESTLEVEL = 32 THEN @Result % 10000
               ELSE dbo.RandomNumber()
             END
  END  

In a discussion, Simon clearly mentioned that:

While the datatype used for storing the list of handles may be ordered by insertion, the order in which the WebDriver implementation iterates over the window handles to insert them has no requirement to be stable. The ordering is arbitrary.

Using Selenium v3.x opening a website in a New Tab through Python is much easier now. We have to induce an WebDriverWait for number_of_windows_to_be(2) and then collect the window handles every time we open a new tab/window and finally iterate through the window handles and switchTo().window(newly_opened) as required. Here is a solution where you can open http://www.google.co.in in the initial TAB and https://www.yahoo.com in the adjacent TAB:

• Code Block:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get("http://www.google.co.in")
  print("Initial Page Title is : %s" %driver.title)
  windows_before  = driver.current_window_handle
  print("First Window Handle is : %s" %windows_before)
  driver.execute_script("window.open('https://www.yahoo.com')")
  WebDriverWait(driver, 10).until(EC.number_of_windows_to_be(2))
  windows_after = driver.window_handles
  new_window = [x for x in windows_after if x != windows_before][0]
  driver.switch_to_window(new_window)
  print("Page Title after Tab Switching is : %s" %driver.title)
  print("Second Window Handle is : %s" %new_window)
  

• Console Output:

  Initial Page Title is : Google
  First Window Handle is : CDwindow-B2B3DE3A222B3DA5237840FA574AF780
  Page Title after Tab Switching is : Yahoo
  Second Window Handle is : CDwindow-D7DA7666A0008ED91991C623105A2EC4

Outro

You can find the java based discussion in Best way to keep track and iterate through tabs and windows using WindowHandles using Selenium

Using @fireant's idea, I wrote up a function to handle overlays. This works well for any position argument (including negative positions).

def overlay_image_alpha(img, img_overlay, pos, alpha_mask):
    """Overlay img_overlay on top of img at the position specified by
    pos and blend using alpha_mask.

    Alpha mask must contain values within the range [0, 1] and be the
    same size as img_overlay.
    """

    x, y = pos

    # Image ranges
    y1, y2 = max(0, y), min(img.shape[0], y + img_overlay.shape[0])
    x1, x2 = max(0, x), min(img.shape[1], x + img_overlay.shape[1])

    # Overlay ranges
    y1o, y2o = max(0, -y), min(img_overlay.shape[0], img.shape[0] - y)
    x1o, x2o = max(0, -x), min(img_overlay.shape[1], img.shape[1] - x)

    # Exit if nothing to do
    if y1 >= y2 or x1 >= x2 or y1o >= y2o or x1o >= x2o:
        return

    channels = img.shape[2]

    alpha = alpha_mask[y1o:y2o, x1o:x2o]
    alpha_inv = 1.0 - alpha

    for c in range(channels):
        img[y1:y2, x1:x2, c] = (alpha * img_overlay[y1o:y2o, x1o:x2o, c] +
                                alpha_inv * img[y1:y2, x1:x2, c])

Usage is:

overlay_image_alpha(img_large,
                    img_small[:, :, 0:3],
                    (x, y),
                    img_small[:, :, 3] / 255.0)

Alternative reason also might be the parent artifact comes from repository which is not accessible from pom.xml, typically private repository. The solution was to provide that repository in pom.xml:

<repositories>
    <repository>
        <id>internal-repo</id>
        <name>internal repository</name>
        <url>https://my/private/repo</url>
        <layout>default</layout>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

In my case the problem was even more complicated due to Eclipse: the repository was active only in special profile (<profiles><profile><id>activate-private-repo</id><repositories>...) and Maven GUI in Eclipse didn't allow to set this profile through Ctrl+Alt+P shortcut.

The solution was to temporarily declare repository outside profile (unconditionally), launch Alt+F5 Maven Update Project, activate profile and put repository declaration back into profile. This is rather Eclipse bug, not Maven bug.

Test the value against NaN:

<xsl:if test="string(number(myNode)) != 'NaN'">
    <!-- myNode is a number -->
</xsl:if>

This is a shorter version (thanks @Alejandro):

<xsl:if test="number(myNode) = myNode">
    <!-- myNode is a number -->
</xsl:if>

You could also use Perl6::Junction.

use Perl6::Junction qw'any';

my @arr = ( 1, 2, 3 );

if( any(@arr) == 1 ){ ... }

It's better if you create a class that has all the query methods, inclusively, in a different package, so instead of typing all the process in every class, you just call the method from that class.

Use Random.nextInt(int).

In your case it would look something like this:

a[i][j] = r.nextInt(101);

window.history.back() does not support reload or refresh of the page. But you can use following if you are okay with an extra refresh

window.history.back()
window.location.reload()

However a real complete solution would be as follows: I wrote a service to keep track of previous page and then navigate to that page with reload:true

Here is how i did it.

'use strict';

angular.module('tryme5App')
    .factory('RouterTracker', function RouterTracker($rootScope) {
          var routeHistory = [];
          var service = {
            getRouteHistory: getRouteHistory
          };

          $rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
              routeHistory = [];
              routeHistory.push({route: from, routeParams: fromParams});
          });

          function getRouteHistory() {
            return routeHistory;
          }

          return service;       
    });

Make sure you have included this js file from you index.html

<script src="scripts/components/util/route.service.js"></script>

Now from you stateprovider or controller you can access this service and navigate

var routeHistory = RouterTracker.getRouteHistory();    
console.log(routeHistory[0].route.name)
$state.go(routeHistory[0].route.name, null, { reload: true });

or alternatively even perform checks and conditional routing

var routeHistory = RouterTracker.getRouteHistory();    
console.log(routeHistory[0].route.name)
if(routeHistory[0].route.name == 'seat') {
      $state.go('seat', null, { reload: true });
} else {
      window.history.back()
}

Make sure you have added RouterTracker as an argument in your function in my case it was :

.state('seat.new', {
                parent: 'seat',
                url: '/new',
                data: {
                    authorities: ['ROLE_USER'],
                },
                onEnter: ['$stateParams', '$state', '$uibModal', 'RouterTracker', function($stateParams, $state, $uibModal, RouterTracker) {
  $uibModal.open({
      //....Open dialog.....
 }).result.then(function(result) {
            var routeHistory = RouterTracker.getRouteHistory();    
            console.log(routeHistory[0].route.name)
            $state.go(routeHistory[0].route.name, null, { reload: true });
 }, function() {
                    $state.go('^');
 })

If you look at either of the following keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\hivelist

You can find a list of the SIDs there with various values, including where their "home paths" which includes their usernames.

I'm not sure how dependable this is and I wouldn't recommend messing about with this unless you're really sure what you're doing.

To build off what Martjin was saying. I'd use string interpolation/formatting.

In Python 2.x which seems to be what you're using due to the lack of parenthesis around the print function you do:

print 'Value is "%d"' % value

In Python 3.x you'd use the format method instead, so you're code would look like this.

message = 'Value is "{}"'
print(message.format(value))

Try this:

!unpack file.zip

If its now working or file is 7z try below

!apt-get install p7zip-full
!p7zip -d file_name.tar.7z
!tar -xvf file_name.tar

Or

!pip install pyunpack
!pip install patool

from pyunpack import Archive
Archive(‘file_name.tar.7z’).extractall(‘path/to/’)
!tar -xvf file_name.tar

Yes, the first function has no relationship with an object instance of that constructor function, you can consider it like a 'static method'.

In JavaScript functions are first-class objects, that means you can treat them just like any object, in this case, you are only adding a property to the function object.

The second function, as you are extending the constructor function prototype, it will be available to all the object instances created with the new keyword, and the context within that function (the this keyword) will refer to the actual object instance where you call it.

Consider this example:

// constructor function
function MyClass () {
  var privateVariable; // private member only available within the constructor fn

  this.privilegedMethod = function () { // it can access private members
    //..
  };
}

// A 'static method', it's just like a normal function 
// it has no relation with any 'MyClass' object instance
MyClass.staticMethod = function () {};

MyClass.prototype.publicMethod = function () {
  // the 'this' keyword refers to the object instance
  // you can access only 'privileged' and 'public' members
};

var myObj = new MyClass(); // new object instance

myObj.publicMethod();
MyClass.staticMethod();

Can't tell you how many times this has caught. me.

Guid myGuid = Guid.NewGuid(); 

Following worked for me from the command line:

aapt dump badging myapp.apk

NOTE: aapt.exe is found in a build-tools sub-folder of SDK. For example:

<sdk_path>/build-tools/23.0.2/aapt.exe

using(NoGateway objNoGateway = new NoGateway())

is equivalent to

try
{
    NoGateway = new NoGateway();
}

finally
{
    NoGateway.Dispose();
}

A finalizer is called upon the GC destroying your object. This can be at a totally different time than when you leave your method. The Dispose of IDisposable is called immediately after you leave the using block. Hence the pattern is usually to use using to free ressources immediately after you don't need them anymore.

The second argument of date is a UNIX timestamp, not a database timestamp string.

You need to convert your database timestamp with strtotime.

<?= date("c", strtotime($post[3])) ?>

I have change all columns width in my case as

            worksheet.Columns[1].ColumnWidth = 7;
            worksheet.Columns[2].ColumnWidth = 15;
            worksheet.Columns[3].ColumnWidth = 15;
            worksheet.Columns[4].ColumnWidth = 15;
            worksheet.Columns[5].ColumnWidth = 18;
            worksheet.Columns[6].ColumnWidth = 8;
            worksheet.Columns[7].ColumnWidth = 13;
            worksheet.Columns[8].ColumnWidth = 17;
            worksheet.Columns[9].ColumnWidth = 17;

Note: Columns in worksheet start with 1 not from 0 as in Arrary.

It's called optional chaining and It's in Typescript 3.7

Optional chaining lets us write code where we can immediately stop running some expressions if we run into a null or undefined

I know this may be too late for a better answer but a desired perfect solution must be a system like positioner. I mean, when system makes a positioning for an Editor field it places the field just up to the keyboard, so as UI/UX rules it is perfect.

What below code makes is the Android way positioning smoothly. First of all we keep the current scroll point as a reference point. Second thing is to find the best positioning scroll point for an editor, to do this we scroll to top, and then request the editor fields to make the ScrollView component to do the best positioning. Gatcha! We've learned the best position. Now, what we'll do is scroll smoothly from the previous point to the point we've found newly. If you want you may omit smooth scrolling by using scrollTo instead of smoothScrollTo only.

NOTE: The main container ScrollView is a member field named scrollViewSignup, because my example was a signup screen, as you may figure out a lot.

view.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(final View view, boolean b) {
            if (b) {
                scrollViewSignup.post(new Runnable() {
                    @Override
                    public void run() {
                        int scrollY = scrollViewSignup.getScrollY();
                        scrollViewSignup.scrollTo(0, 0);
                        final Rect rect = new Rect(0, 0, view.getWidth(), view.getHeight());
                        view.requestRectangleOnScreen(rect, true);

                        int new_scrollY = scrollViewSignup.getScrollY();
                        scrollViewSignup.scrollTo(0, scrollY);
                        scrollViewSignup.smoothScrollTo(0, new_scrollY);
                    }
                });
            }
        }
    });

If you want to use this block for all EditText instances, and quickly integrate it with your screen code. You can simply make a traverser like below. To do this, I've made the main OnFocusChangeListener a member field named focusChangeListenerToScrollEditor, and call it during onCreate as below.

traverseEditTextChildren(scrollViewSignup, focusChangeListenerToScrollEditor);

And the method implementation is as below.

private void traverseEditTextChildren(ViewGroup viewGroup, View.OnFocusChangeListener focusChangeListenerToScrollEditor) {
    int childCount = viewGroup.getChildCount();
    for (int i = 0; i < childCount; i++) {
        View view = viewGroup.getChildAt(i);
        if (view instanceof EditText)
        {
            ((EditText) view).setOnFocusChangeListener(focusChangeListenerToScrollEditor);
        }
        else if (view instanceof ViewGroup)
        {
            traverseEditTextChildren((ViewGroup) view, focusChangeListenerToScrollEditor);
        }
    }
}

So, what we've done here is making all EditText instance children to call the listener at focus.

To reach this solution, I've checked it out all the solutions here, and generated a new solution for better UI/UX result.

Many thanks to all other answers inspiring me much.

The essential difference between /* and / is that a servlet with mapping /* will be selected before any servlet with an extension mapping (like *.html), while a servlet with mapping / will be selected only after extension mappings are considered (and will be used for any request which doesn't match anything else---it is the "default servlet").

In particular, a /* mapping will always be selected before a / mapping. Having either prevents any requests from reaching the container's own default servlet.

Either will be selected only after servlet mappings which are exact matches (like /foo/bar) and those which are path mappings longer than /* (like /foo/*). Note that the empty string mapping is an exact match for the context root (http://host:port/context/).

Running the risk of getting another Necromancer badge, I would like to add one very good use for uintptr_t (or even intptr_t) and that is writing testable embedded code. I write mostly embedded code targeted at various arm and currently tensilica processors. These have various native bus width and the tensilica is actually a Harvard architecture with separate code and data buses that can be different widths. I use a test driven development style for much of my code which means I do unit tests for all the code units I write. Unit testing on actual target hardware is a hassle so I typically write everything on an Intel based PC either in Windows or Linux using Ceedling and GCC. That being said, a lot of embedded code involves bit twiddling and address manipulations. Most of my Intel machines are 64 bit. So if you are going to test address manipulation code you need a generalized object to do math on. Thus the uintptr_t give you a machine independent way of debugging your code before you try deploying to target hardware. Another issue is for the some machines or even memory models on some compilers, function pointers and data pointers are different widths. On those machines the compiler may not even allow casting between the two classes, but uintptr_t should be able to hold either. -- Edit -- Was pointed out by @chux, this is not part of the standard and functions are not objects in C. However it usually works and since many people don't even know about these types I usually leave a comment explaining the trickery. Other searches in SO on uintptr_t will provide further explanation. Also we do things in unit testing that we would never do in production because breaking things is good.

There's another important point in constructor chaining: order. Why? Let's say that you have an object being constructed at runtime by a framework that expects it's default constructor. If you want to be able to pass in values while still having the ability to pass in constructor argments when you want, this is extremely useful.

I could for instance have a backing variable that gets set to a default value by my default constructor but has the ability to be overwritten.

public class MyClass
{
  private IDependency _myDependency;
  MyClass(){ _myDependency = new DefaultDependency(); }
  MYClass(IMyDependency dependency) : this() {
    _myDependency = dependency; //now our dependency object replaces the defaultDependency
  }
}

Jordans analysis of why the $_POST-array isn't populated is correct. However, you can use

$data = file_get_contents("php://input");

to just retrieve the http body and handle it yourself. See PHP input/output streams.

From a protocol perspective this is actually more correct, since you're not really processing http multipart form data anyway. Also, use application/json as content-type when posting your request.

Changing the content of the .git/config file helps as Alex said above. I experienced the same problem and I think it was because I changed my Github username. The local files could not be updated with the changes. So perhaps anytime you change your username you might consider running

git remote add origin your_ssh_link_from_github

I hope this helps ;)

For a cell to self-reference itself:

INDIRECT(ADDRESS(ROW(), COLUMN()))

For a cell to self-reference its column:

INDIRECT(ADDRESS(1,COLUMN()) & ":" & ADDRESS(65536, COLUMN()))

For a cell to self-reference its row:

INDIRECT(ADDRESS(ROW(),1) & ":" & ADDRESS(ROW(),256))
or
INDIRECT("A" & ROW() & ":IV" & ROW())

The numbers are for 2003 and earlier, use column:XFD and row:1048576 for 2007+.

Note: The INDIRECT function is volatile and should only be used when needed.

Due to my subversion state, I had to get creative. svn st showed M,A and ~ statuses. I only wanted M and A so...

svn st | grep ^[A\|M] | cut -d' ' -f8- > targets.txt

This command says find all the lines output by svn st that start with M or A, cut using space delimiter, then get colums 8 to the end. Dump that into targets.txt and overwrite.

Then modify targets.txt to prune the file list further. Then run below to commit:

svn ci -m "My commit message" --targets targets.txt

Probably not the most common use case, but hopefully it helps someone.

This one worked for me:

tr can be more concise for removing characters than sed or awk, especially when you want to remove different characters from a string.

Removing double quotes:

echo '"Hi"' | tr -d \"
# Produces Hi without quotes

Removing different kinds of brackets:

echo '[{Hi}]' | tr -d {}[]
# Produces Hi without brackets

-d stands for "delete".

• Toggle case "HellO" to "hELLo" with g~ then a movement.
• Uppercase "HellO" to "HELLO" with gU then a movement.
• Lowercase "HellO" to "hello" with gu then a movement.

You can use native javascript function

var obj = {a:1,b:2};

Object.keys(obj).forEach(function(key){
    console.log(key, obj[el])

or create an object prototype foreach, but it usually causes issues with other frameworks

if (!Object.prototype.forEach) {
  Object.defineProperty(Object.prototype, 'forEach', {
    value: function (callback, thisArg) {
      if (this == null) {
        throw new TypeError('Not an object');
      }
      thisArg = thisArg || window;
      for (var key in this) {
        if (this.hasOwnProperty(key)) {
          callback.call(thisArg, this[key], key, this);
        }
      }
    }
  });
}

var obj = {a:1,b:2};

obj.forEach(function(key, value){
    console.log(key, value)
})

I find this quite tricky, but there is some information on it here at the MatPlotLib FAQ. It is rather cumbersome, and requires finding out about what space individual elements (ticklabels) take up...

Update: The page states that the tight_layout() function is the easiest way to go, which attempts to automatically correct spacing.

Otherwise, it shows ways to acquire the sizes of various elements (eg. labels) so you can then correct the spacings/positions of your axes elements. Here is an example from the above FAQ page, which determines the width of a very wide y-axis label, and adjusts the axis width accordingly:

import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
ax.set_yticks((2,5,7))
labels = ax.set_yticklabels(('really, really, really', 'long', 'labels'))

def on_draw(event):
   bboxes = []
   for label in labels:
       bbox = label.get_window_extent()
       # the figure transform goes from relative coords->pixels and we
       # want the inverse of that
       bboxi = bbox.inverse_transformed(fig.transFigure)
       bboxes.append(bboxi)

   # this is the bbox that bounds all the bboxes, again in relative
   # figure coords
   bbox = mtransforms.Bbox.union(bboxes)
   if fig.subplotpars.left < bbox.width:
       # we need to move it over
       fig.subplots_adjust(left=1.1*bbox.width) # pad a little
       fig.canvas.draw()
   return False

fig.canvas.mpl_connect('draw_event', on_draw)

plt.show()

By using an href attribute inside an anchor tag you can scroll the page to a specific element using a # in front of the elements id name.

Also, here is some jQuery/JS that will accomplish putting variables into a div.

<html>
<body>

Click <a href="#myContent">here</a> to scroll to the myContent section.

<div id="myContent">
...
</div>

<script>
    var myClassName = "foo";

    $(function() {
        $("#myContent").addClass(myClassName);
    });
</script>

</body>

In my case the problem was that I hadn't Debug view open in Debug perspective, so:

1 - Be sure you have debug perspective opened:

2 - Be sure you have debug view opened:

Have you tried simply 'reboot' with adb?

  adb reboot

Also you can run complete shell scripts (e.g. to reboot your emulator) via adb:

 adb shell <command>

Do doubles always have 16 significant figures while floats always have 7 significant figures?

No. Doubles always have 53 significant bits and floats always have 24 significant bits (except for denormals, infinities, and NaN values, but those are subjects for a different question). These are binary formats, and you can only speak clearly about the precision of their representations in terms of binary digits (bits).

This is analogous to the question of how many digits can be stored in a binary integer: an unsigned 32 bit integer can store integers with up to 32 bits, which doesn't precisely map to any number of decimal digits: all integers of up to 9 decimal digits can be stored, but a lot of 10-digit numbers can be stored as well.

Why don't doubles have 14 significant figures?

The encoding of a double uses 64 bits (1 bit for the sign, 11 bits for the exponent, 52 explicit significant bits and one implicit bit), which is double the number of bits used to represent a float (32 bits).

One simple solution to the problem -

JAVA_HOME=/usr/lib/jvm/java-6-sun/ mvn clean install

On Mac, it would look something like -

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home/ mvn clean install

PS: One special case that i found is the above given command does not work on 'fish' shell. I also had bash shell available and it worked fine there. just use command 'bash' to switch to bash shell.

$order = new WC_Order( $post_id ); 

If you

echo $order->id;

then you'll be returned the id of the post from which the order is made. As you've already got that, it's probably not what you want.

echo $order->get_order_number();

will return the id of the order (with a # in front of it). To get rid of the #,

echo trim( str_replace( '#', '', $order->get_order_number() ) );

as per the accepted answer.

You can try a simple ffmpeg wrapper .NET from here : http://ivolo.mit.edu/post/Convert-Audio-Video-to-Any-Format-using-C.aspx

It depends on what you mean. Do you want actual tab characters in your file to appear 4 spaces wide, or by "tab" do you actually mean an indent, generated by pressing the tab key, which would result in the file literally containing (up to) 4 space characters for each "tab" you type?

Depending on your answer, one of the following sets of settings should work for you:

• For tab characters that appear 4-spaces-wide:

  set tabstop=4
  

  If you're using actual tab character in your source code you probably also want these settings (these are actually the defaults, but you may want to set them defensively):

  set softtabstop=0 noexpandtab
  

  Finally, if you want an indent to correspond to a single tab, you should also use:

  set shiftwidth=4
  

• For indents that consist of 4 space characters but are entered with the tab key:

  set tabstop=8 softtabstop=0 expandtab shiftwidth=4 smarttab
  

To make the above settings permanent add these lines to your vimrc.

In case you need to make adjustments, or would simply like to understand what these options all mean, here's a breakdown of what each option means:

tabstop

The width of a hard tabstop measured in "spaces" -- effectively the (maximum) width of an actual tab character.

shiftwidth

The size of an "indent". It's also measured in spaces, so if your code base indents with tab characters then you want shiftwidth to equal the number of tab characters times tabstop. This is also used by things like the =, > and < commands.

softtabstop

Setting this to a non-zero value other than tabstop will make the tab key (in insert mode) insert a combination of spaces (and possibly tabs) to simulate tab stops at this width.

expandtab

Enabling this will make the tab key (in insert mode) insert spaces instead of tab characters. This also affects the behavior of the retab command.

smarttab

Enabling this will make the tab key (in insert mode) insert spaces or tabs to go to the next indent of the next tabstop when the cursor is at the beginning of a line (i.e. the only preceding characters are whitespace).

For more details on any of these see :help 'optionname' in vim (e.g. :help 'tabstop')

For new Mysql 5.7 for some reason bin commands of Mysql not attached to the shell:

1. Restart the Mac after install.

2. Start Mysql:

   System Preferences > Mysql > Start button

3. Go to Mysql install folder in terminal:

   $ cd /usr/local/mysql/bin/

4. Access to Mysql:

   $ ./mysql -u root -p

and enter the initial password given to the installation.

4. In Mysql terminal change password:

   mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPassword';

No, there isn't a decent solution for body type, unless you're willing to cater only to those with bleeding-edge browsers.

Microsoft has WEFT, their own proprietary font-embedding technology, but I haven't heard it talked about in years, and I know no one who uses it.

I get by with sIFR for display type (headlines, titles of blog posts, etc.) and using one of the less-worn-out web-safe fonts for body type (like Trebuchet MS). If you're bored with all the web-safe fonts, you're probably defining the term too narrowly — look at this matrix of stock fonts that ship with major OSes and chances are you'll be able to find a font cascade that will catch nearly all web users.

For instance: font-family: "Lucida Grande", "Verdana", sans-serif is a common font cascade; OS X comes with Lucida Grande, but those with Windows will get Verdana, a web-safe font with letters of similar size and shape to Lucida Grande. Linux users will also get Verdana if they've installed the web-safe fonts package that exists in most distros' package managers, or else they'll fall back to an ordinary sans-serif.

Here is a sample script that I recently used in a Gateway POST transaction that receives a GET response. Are you using this in a custom C# form? Whatever your purpose, just replace the String fields (username, password, etc.) with the parameters from your form.

private String readHtmlPage(string url)
   {

    //setup some variables

    String username  = "demo";
    String password  = "password";
    String firstname = "John";
    String lastname  = "Smith";

    //setup some variables end

      String result = "";
      String strPost = "username="+username+"&password="+password+"&firstname="+firstname+"&lastname="+lastname;
      StreamWriter myWriter = null;

      HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
      objRequest.Method = "POST";
      objRequest.ContentLength = strPost.Length;
      objRequest.ContentType = "application/x-www-form-urlencoded";

      try
      {
         myWriter = new StreamWriter(objRequest.GetRequestStream());
         myWriter.Write(strPost);
      }
      catch (Exception e) 
      {
         return e.Message;
      }
      finally {
         myWriter.Close();
      }

      HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
      using (StreamReader sr = 
         new StreamReader(objResponse.GetResponseStream()) )
      {
         result = sr.ReadToEnd();

         // Close and clean up the StreamReader
         sr.Close();
      }
      return result;
   }

Using LEFT JOIN/IS NULL:

DELETE b FROM BLOB b 
  LEFT JOIN FILES f ON f.id = b.fileid 
      WHERE f.id IS NULL

Using NOT EXISTS:

DELETE FROM BLOB 
 WHERE NOT EXISTS(SELECT NULL
                    FROM FILES f
                   WHERE f.id = fileid)

Using NOT IN:

DELETE FROM BLOB
 WHERE fileid NOT IN (SELECT f.id 
                        FROM FILES f)

Warning

Whenever possible, perform DELETEs within a transaction (assuming supported - IE: Not on MyISAM) so you can use rollback to revert changes in case of problems.

To find out concept of DOM element it is essential to understand concept of Dynamic HTML and DOM. Everything is started from the time that requirements of all stockholders of web pages are enhanced. They wanted the Web pages that can be more interactive, dynamic and lively. In addition, to reach this goal, developers required the tools and mechanisms that via them the presentation and content of each section of web page can be modified or manipulated. Therefore the concept of Dynamic HTML is created. To understand it, a great definition for Dynamic HTML is accessible in Wikipedia:

Dynamic HTML, or DHTML, is an umbrella term for a collection of technologies used together to create interactive and animated websites by using a combination of a static markup language (such as HTML), a client-side scripting language (such as JavaScript), a presentation definition language (such as CSS), and the Document Object Model (DOM).

So, writing standard DHTML web pages are standardized in three fields, including client-side scripting language (such as JavaScript), a presentation definition language (such as CSS) and uniform programming interface(API) to access and modify the Web page (Document Object Model). This activity is performed by W3C and others. Also to solve the problem of cross browser, W3C tried to reach a general consensus (with different browser vendors) about scripts to access and manipulate HTML and XML documents via Document Object Model (DOM) as a standard application programming interface (API).

But the main question is that how they designed the structure of Document Object Model to meet their needs. Their solution was simple but wonderful. They used a hierarchical structure such as tree which at the root of the tree you can find document object, also each node is equivalent of a HTML elements (DOM element). This abstraction of your web page give you a great facility to access any HTML element, style sheets, and ... . To understand it better you can map each indent of your HTML code to each level of DOM tree. Please pay attention to this example:

Your HTML:

<!DOCTYPE html>
<html>
    <head>
    </head>
    <body>
        <p>...</p>
        <ul>
            <li>...</li>
        </ul>
        <table>
            <tr>...</tr>
        </table>
    </body>
</html> 

DOM Structure:

    document
      |    .    
    <html>    .
    /   \         .
 <head> <body>  styleSheets
        /  \  \
      <p> <ul> <table>
      /     \       \
    text    <li>    <tr>  

So, each node of this hierarchical structure (DOM tree) refers to a DOM element. To learn more use tis reference

Use mvn -X or mvn --debug to find out from which different locations Maven reads settings.xml. This switch activates debug logging. Just check the first lines of mvn --debug | findstr /i /c:using /c:reading.

Right, Maven uses the Java system property user.home as location for the .m2 folder.

But user.home does not always resolve to %USERPROFILE%\.m2. If you have moved the location of your Desktop folder to another place, user.home might resolve to the parent directory of this new Desktop folder. This happens when using Windows Vista or a more recent Windows together with Java 7 or any older Java version.

The blog post Java’s “user.home” is Wrong on Windows describes it very well and gives links to the official bug reports. The bug is marked as resolved in Java 8. The comment of the blog's visitor Lars proposes a nice workaround.

you could use file_get_contents if you are wanting to store the source as a variable however curl is a better practive.

$url = file_get_contents('http://example.com');
echo $url; 

this solution will display the webpage on your site. However curl is a better option.

Use this function begining from SQL SERVER 2016

Select Count(value) From STRING_SPLIT('AAA AAA AAA',' ');

-- Output : 3 

When This function used with count function it gives you how many character exists in string

Tryprint

Example:

print "Hello World!"
print
print "Hi!"

Hope this works!:)

I would recommend using Wireshark, which has a "Follow TCP Stream" option that makes it very easy to see the full requests and responses for a particular TCP connection. If you would prefer to use the command line, you can try tcpflow, a tool dedicated to capturing and reconstructing the contents of TCP streams.

Other options would be using an HTTP debugging proxy, like Charles or Fiddler as EricLaw suggests. These have the advantage of having specific support for HTTP to make it easier to deal with various sorts of encodings, and other features like saving requests to replay them or editing requests.

You could also use a tool like Firebug (Firefox), Web Inspector (Safari, Chrome, and other WebKit-based browsers), or Opera Dragonfly, all of which provide some ability to view the request and response headers and bodies (though most of them don't allow you to see the exact byte stream, but instead how the browsers parsed the requests).

And finally, you can always construct requests by hand, using something like telnet, netcat, or socat to connect to port 80 and type the request in manually, or a tool like htty to help easily construct a request and inspect the response.

Yes, you want to use tee:

tee - read from standard input and write to standard output and files

Just pipe your command to tee and pass the file as an argument, like so:

exec 1 | tee ${LOG_FILE}
exec 2 | tee ${LOG_FILE}

This both prints the output to the STDOUT and writes the same output to a log file. See man tee for more information.

Note that this won't write stderr to the log file, so if you want to combine the two streams then use:

exec 1 2>&1 | tee ${LOG_FILE}

You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :

BEGIN TRANSACTION

update A
set A.ORG_NAME =  @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID

update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
    on B.ORG_ID = A.ORG_ID
    and A.ORG_ID = @ORG_ID
