I like using (open source and gui friendly) Quantum GIS to convert the shapefile to kml.

Google Maps API supports only a subset of the KML standard. One limitation is file size.

To reduce your file size, you can Quantum GIS's "simplify geometries" function. This "smooths" polygons.

Then you can select your layer and do a "save as kml" on it.

If you need to process a bunch of files, the process can be batched with Quantum GIS's ogr2ogr command from osgeo4w shell.

Finally, I recommend zipping your kml (with your favorite compression program) for reduced file size and saving it as kmz.

If you use Python 2, don't forget to add the UTF-8 file encoding comment on the first line of your script.

# -*- coding: UTF-8 -*-

This will fix some Unicode problems and make your life easier.

when you pushing code to another branch just follow the below git command. Remember demo is my other branch name you can replace with your branch name.

git push origin master:demo

List<String> arrayList = new ArrayList<String>();

Is generic where you want to hide implementation details while returning it to client, at later point of time you may change implementation from ArrayList to LinkedList transparently.

This mechanism is useful in cases where you design libraries etc., which may change their implementation details at some point of time with minimal changes on client side.

ArrayList<String> arrayList = new ArrayList<String>();

This mandates you always need to return ArrayList. At some point of time if you would like to change implementation details to LinkedList, there should be changes on client side also to use LinkedList instead of ArrayList.

Try this:

=FORMAT(Cdate(today), "dd-MM-yyyy")

or

=FORMAT(Cdate(today), "MM-dd-yyyy")

or

=FORMAT(Cdate(today), "yyyy-MM-dd")

or

=Report Generation Date: " & FORMAT(Cdate(today), "dd-MM-yyyy")

You should format the date in the same format your customer (internal or external) wants to see the date. For example In one of my servers it is running on American date format (MM-dd-yyyy) and on my reports I must ensure the dates displayed are European (yyyy-MM-dd).

You can use "Gena" library. It closely resembles stl::vector in pure C89.

From the README, it features:

• Access vector elements just like plain C arrays: vec[k][j];
• Have multi-dimentional arrays;
• Copy vectors;
• Instantiate necessary vector types once in a separate module, instead of doing this every time you needed a vector;
• You can choose how to pass values into a vector and how to return them from it: by value or by pointer.

You can check it out here:

Have you considered using span instead of div? It is the in-line version of div.

I had the same:

All created by user files saved in C:\xampp\htdocs directory by default, so no need to type the default path in a browser window, just type http://localhost/yourfilename.php or http://localhost/yourfoldername/yourfilename.php this will show you the content of your new page.

The mysql command by default uses UNIX sockets to connect to MySQL.

If you're using MariaDB, you need to load the Unix Socket Authentication Plugin on the server side.

You can do it by editing the [mysqld] configuration like this:

[mysqld]
plugin-load-add = auth_socket.so

Depending on distribution, the config file is usually located at /etc/mysql/ or /usr/local/etc/mysql/

Use setRoundingMode, set the RoundingMode explicitly to handle your issue with the half-even round, then use the format pattern for your required output.

Example:

DecimalFormat df = new DecimalFormat("#.####");
df.setRoundingMode(RoundingMode.CEILING);
for (Number n : Arrays.asList(12, 123.12345, 0.23, 0.1, 2341234.212431324)) {
    Double d = n.doubleValue();
    System.out.println(df.format(d));
}

gives the output:

12
123.1235
0.23
0.1
2341234.2125

EDIT: The original answer does not address the accuracy of the double values. That is fine if you don't care much whether it rounds up or down. But if you want accurate rounding, then you need to take the expected accuracy of the values into account. Floating point values have a binary representation internally. That means that a value like 2.7735 does not actually have that exact value internally. It can be slightly larger or slightly smaller. If the internal value is slightly smaller, then it will not round up to 2.7740. To remedy that situation, you need to be aware of the accuracy of the values that you are working with, and add or subtract that value before rounding. For example, when you know that your values are accurate up to 6 digits, then to round half-way values up, add that accuracy to the value:

Double d = n.doubleValue() + 1e-6;

To round down, subtract the accuracy.

You can try to implement direct link node -> fastcgi -> php. In the previous answer, nginx serves php requests using http->fastcgi serialisation->unix socket->php and node requests as http->nginx reverse proxy->node http server.

It seems that node-fastcgi paser is useable at the moment, but only as a node fastcgi backend. You need to adopt it to use as a fastcgi client to php fastcgi server.

UConverter can be used since PHP 5.5. UConverter is better the choice if you use intl extension and don't use mbstring.

function replace_invalid_byte_sequence($str)
{
    return UConverter::transcode($str, 'UTF-8', 'UTF-8');
}

function replace_invalid_byte_sequence2($str)
{
    return (new UConverter('UTF-8', 'UTF-8'))->convert($str);
}

htmlspecialchars can be used to remove invalid byte sequence since PHP 5.4. Htmlspecialchars is better than preg_match for handling large size of byte and the accuracy. A lot of the wrong implementation by using regular expression can be seen.

function replace_invalid_byte_sequence3($str)
{
    return htmlspecialchars_decode(htmlspecialchars($str, ENT_SUBSTITUTE, 'UTF-8'));
}

This is still the highest SO-question on Google when searching for this error, so let's bump it.

When getting this error and not wanting to deep-dive into the NGINX settings immediately, you might want to check your outputs to the debug console. In my case I was outputting loads of text to the FirePHP / Chromelogger console, and since this is all sent as a header, it was causing the overflow.

It might not be needed to change the webserver settings if this error is caused by just sending insane amounts of log messages.

A good way is to derive from TcpClient and override the Disposing(bool) method:

class MyClient : TcpClient {
    public bool IsDead { get; set; }
    protected override void Dispose(bool disposing) {
        IsDead = true;
        base.Dispose(disposing);
    }
}

Which won't work if the other code created the instance. Then you'll have to do something desperate like using Reflection to get the value of the private m_CleanedUp member. Or catch the exception.

Frankly, none is this is likely to come to a very good end. You really did want to write to the TCP port. But you won't, that buggy code you can't control is now in control of your code. You've increased the impact of the bug. Talking to the owner of that code and working something out is by far the best solution.

EDIT: A reflection example:

using System.Reflection;
public static bool SocketIsDisposed(Socket s)
{
   BindingFlags bfIsDisposed = BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.GetProperty;
   // Retrieve a FieldInfo instance corresponding to the field
   PropertyInfo field = s.GetType().GetProperty("CleanedUp", bfIsDisposed);
   // Retrieve the value of the field, and cast as necessary
   return (bool)field.GetValue(s, null);
}

There is additionally collections’ stream() util with Java 8

collection.forEach((temp) -> {
            System.out.println(temp);
});

or

collection.forEach(System.out::println);

I prefer outputting my data into XML (using Castor, XStream or JAXB), then transforming it using a XSLT stylesheet into XSL-FO and render that with Apache FOP into PDF. Worked so far for 10-page reports and 400-page manuals. I found this more flexible and stylable than generating PDFs in code using iText.

Surprisingly the Data Export in the MySql Workbench is not just for data, in fact it is ideal for generating SQL scripts for the whole database (including views, stored procedures and functions) with just a few clicks. If you want just the scripts and no data simply select the "Skip table data" option. It can generate separate files or a self contained file. Here are more details about the feature: http://dev.mysql.com/doc/workbench/en/wb-mysql-connections-navigator-management-data-export.html

Mabey you only need:

Step one:

grant all privileges on *.* to 'user'@'IP' identified by 'password';

or

grant all privileges on *.* to 'user'@'%' identified by 'password';

Step two:

sudo ufw allow 3306

Step three:

sudo service mysql restart

code:

If there is space between the letters of the font, you need to use quote.

A little late to the party, but this is how I did it for an insert:

DECLARE @ManagerID AS Varchar (25) = 'NA'
DECLARE @ManagerEmail AS Varchar (50) = 'NA'
Declare @RecordCount AS int = 0

SET @ManagerID = ?
SET @ManagerEmail = ?
SET @RecordCount = ?

It's not necessary to call repaint unless you need to render something specific onto a component. "Something specific" meaning anything that isn't provided internally by the windowing toolkit you're using.

Directory Services/LDAP lookups can be used to serve this purpose. It involves some changes at infrastructure level, but most production environments have such provision

Simply convert int to NSString use :

  int x=10;

  NSString *strX=[NSString stringWithFormat:@"%d",x];

exec

executes a command and never returns. It's like a return statement in a function.

If the command is not found exec returns false. It never returns true, because if the command is found it never returns at all. There is also no point in returning STDOUT, STDERR or exit status of the command. You can find documentation about it in perlfunc, because it is a function.

system

executes a command and your Perl script is continued after the command has finished.

The return value is the exit status of the command. You can find documentation about it in perlfunc.

backticks

like system executes a command and your perl script is continued after the command has finished.

In contrary to system the return value is STDOUT of the command. qx// is equivalent to backticks. You can find documentation about it in perlop, because unlike system and execit is an operator.

Other ways

What is missing from the above is a way to execute a command asynchronously. That means your perl script and your command run simultaneously. This can be accomplished with open. It allows you to read STDOUT/STDERR and write to STDIN of your command. It is platform dependent though.

There are also several modules which can ease this tasks. There is IPC::Open2 and IPC::Open3 and IPC::Run, as well as Win32::Process::Create if you are on windows.

CSTR({number_field}, 0, '')

The second placeholder is for decimals.

The last placeholder is for thousands separator.

(\d+)\s+(\(.*?\))?\s?Z

Note the escaped parentheses, and the ? (zero or once) quantifiers. Any of the groups you don't want to capture can be (?: non-capture groups).

I agree about the spaces. \s is a better option there. I also changed the quantifier to insure there are digits at the beginning. As far as newlines, that would depend on context: if the file is parsed line by line it won't be a problem. Another option is to anchor the start and end of the line (add a ^ at the front and a $ at the end).

You could use:

System.IO.File.Exists(@"c:\temp\test.txt");

It depends on your scenario (this isn't really suitable for a production environment), but here is one way:

Creating a MySQL Docker Container

This gist of it is to use a directory on your host for data persistence.

You will need to have a datetime column in a table. Then you can do an insert like the following to insert the current date:

INSERT INTO MyTable (MyDate) Values (GetDate())

If it is not today's date then you should be able to use a string and specify the date format:

INSERT INTO MyTable (MyDate) Values (Convert(DateTime,'19820626',112)) --6/26/1982

You do not always need to convert the string either, often you can just do something like:

INSERT INTO MyTable (MyDate) Values ('06/26/1982') 

And SQL Server will figure it out for you.

Make is behaving correctly. hello already exists and is not older than the .c files, and therefore there is no more work to be done. There are four scenarios in which make will need to (re)build:

• If you modify one of your .c files, then it will be newer than hello, and then it will have to rebuild when you run make.
• If you delete hello, then it will obviously have to rebuild it
• You can force make to rebuild everything with the -B option. make -B all
• make clean all will delete hello and require a rebuild. (I suggest you look at @Mat's comment about rm -f *.o hello

At some point, I suppose you will add your programatically created LinearLayout to some root layout that you defined in .xml. This is just a suggestion of mine and probably one of many solutions, but it works: Simply set an ID for the programatically created layout, and add it to the root layout that you defined in .xml, and then use the set ID to add the Fragment.

It could look like this:

LinearLayout rowLayout = new LinearLayout();
rowLayout.setId(whateveryouwantasid);
// add rowLayout to the root layout somewhere here

FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTransaction = fragMan.beginTransaction();   

Fragment myFrag = new ImageFragment();
fragTransaction.add(rowLayout.getId(), myFrag , "fragment" + fragCount);
fragTransaction.commit();

Simply choose whatever Integer value you want for the ID:

rowLayout.setId(12345);

If you are using the above line of code not just once, it would probably be smart to figure out a way to create unique-IDs, in order to avoid duplicates.

UPDATE:

Here is the full code of how it should be done: (this code is tested and works) I am adding two Fragments to a LinearLayout with horizontal orientation, resulting in the Fragments being aligned next to each other. Please also be aware, that I used a fixed height and width of 200dp, so that one Fragment does not use the full screen as it would with "match_parent".

MainActivity.java:

public class MainActivity extends Activity {

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        LinearLayout fragContainer = (LinearLayout) findViewById(R.id.llFragmentContainer);

        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.HORIZONTAL);

        ll.setId(12345);

        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 1"), "someTag1").commit();
        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 2"), "someTag2").commit();

        fragContainer.addView(ll);
    }
}

TestFragment.java:

public class TestFragment extends Fragment {

    public static TestFragment newInstance(String text) {

        TestFragment f = new TestFragment();

        Bundle b = new Bundle();
        b.putString("text", text);
        f.setArguments(b);
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v =  inflater.inflate(R.layout.fragment, container, false);

        ((TextView) v.findViewById(R.id.tvFragText)).setText(getArguments().getString("text"));     
        return v;
    }
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rlMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:id="@+id/llFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="19dp"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

fragment.xml:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200dp"
    android:layout_height="200dp" >

    <TextView
        android:id="@+id/tvFragText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="" />

</RelativeLayout>

And this is the result of the above code: (the two Fragments are aligned next to each other)

I think this log entry Local package.json exists, but node_modules missing, did you mean to install? has gave me the solution.

npm install && npm run dev

Delegates are the way to go.

As seen with other answers using views might get outdated. Who knows tomorrow there might be another wrapper and may need to use cell superview]superview]superview]superview]. And if you use tags you would end up with n number of if else conditions to identify the cell. To avoid all of that set up delegates. (By doing so you will be creating a re usable cell class. You can use the same cell class as a base class and all you have to do is implement the delegate methods.)

First we need a interface (protocol) which will be used by cell to communicate(delegate) button clicks. (You can create a separate .h file for protocol and include in both table view controller and custom cell classes OR just add it in custom cell class which will anyway get included in table view controller)

@protocol CellDelegate <NSObject>
- (void)didClickOnCellAtIndex:(NSInteger)cellIndex withData:(id)data;
@end

Include this protocol in custom cell and table view controller. And make sure table view controller confirms to this protocol.

In custom cell create two properties :

@property (weak, nonatomic) id<CellDelegate>delegate;
@property (assign, nonatomic) NSInteger cellIndex;

In UIButton IBAction delegate click : (Same can be done for any action in custom cell class which needs to be delegated back to view controller)

- (IBAction)buttonClicked:(UIButton *)sender {
    if (self.delegate && [self.delegate respondsToSelector:@selector(didClickOnCellAtIndex:withData:)]) {
        [self.delegate didClickOnCellAtIndex:_cellIndex withData:@"any other cell data/property"];
    }
}

In table view controller cellForRowAtIndexPath after dequeing the cell, set the above properties.

cell.delegate = self;
cell.cellIndex = indexPath.row; // Set indexpath if its a grouped table.

And implement the delegate in table view controller:

- (void)didClickOnCellAtIndex:(NSInteger)cellIndex withData:(id)data
{
    // Do additional actions as required.
    NSLog(@"Cell at Index: %d clicked.\n Data received : %@", cellIndex, data);
}

This would be the ideal approach to get custom cell button actions in table view controller.

<a href="#"><button type="button" class="btn btn-info btn-block regular-link"> <span class="text">Create New Board</span></button></a>

We can use btn-block for automatic responsive.

You create a new project. The new project is your EAR assembly project which contains your two dependencies for your EJB project and your WAR project.

So you actually have three maven projects here. One EJB. One WAR. One EAR that pulls the two parts together and creates the ear.

Deployment descriptors can be generated by maven, or placed inside the resources directory in the EAR project structure.

The maven-ear-plugin is what you use to configure it, and the documentation is good, but not quite clear if you're still figuring out how maven works in general.

So as an example you might do something like this:

jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

after that everything worked very well, even without any "-extension RANDR" switch.

Simply use the macros from <float.h> and the variable-width conversion specifier (".*"):

float f = 3.14159265358979323846;
printf("%.*f\n", FLT_DIG, f);

Try this:

foreach($array as $k => $obj) { 
    $obj->{'newKey'} = "value"; 
}

If you define classproperty as follows, then your example works exactly as you requested.

class classproperty(object):
    def __init__(self, f):
        self.f = f
    def __get__(self, obj, owner):
        return self.f(owner)

The caveat is that you can't use this for writable properties. While e.I = 20 will raise an AttributeError, Example.I = 20 will overwrite the property object itself.

You may want to look at IBExpert Personal Edition. While not open source, this is a very good tool for designing, building, and administering Firebird and InterBase databases.

The Personal Edition is free, but some of the more advanced features are not available. Still, even without the slick extras, the free version is very powerful.

to make your code look better when viewing source

$variable = 'foo';
echo "this is my php variable $variable \n";
echo "this is another php echo here $variable\n";

your code when view source will look like, with nice line returns thanks to \n

this is my php variable foo
this is another php echo here foo

I had to do both changes below to hide the status bar:

Add this code to the view controller where you want to hide the status bar:

- (BOOL)prefersStatusBarHidden
{
    return YES;
}

Add this to your .plist file (go to 'info' in your application settings)

View controller-based status bar appearance --- NO

Then you can call this line to hide the status bar:

[[UIApplication sharedApplication] setStatusBarHidden:YES];

Yes, you can use substitutions and check against the original string:

if not x%str1:bcd=%==x%str1% echo It contains bcd

The %str1:bcd=% bit will replace a bcd in str1 with an empty string, making it different from the original.

If the original didn't contain a bcd string in it, the modified version will be identical.

Testing with the following script will show it in action:

@setlocal enableextensions enabledelayedexpansion
@echo off
set str1=%1
if not x%str1:bcd=%==x%str1% echo It contains bcd
endlocal

And the results of various runs:

c:\testarea> testprog hello

c:\testarea> testprog abcdef
It contains bcd

c:\testarea> testprog bcd
It contains bcd

A couple of notes:

• The if statement is the meat of this solution, everything else is support stuff.
• The x before the two sides of the equality is to ensure that the string bcd works okay. It also protects against certain "improper" starting characters.

Suggest you add handling to test if any of the sheets to be renamed already exist:

Sub Test()

Dim ws As Worksheet
Dim ws1 As Worksheet
Dim strErr As String

On Error Resume Next
For Each ws In ActiveWorkbook.Sheets
Set ws1 = Sheets(ws.Name & "_v1")
    If ws1 Is Nothing Then
        ws.Name = ws.Name & "_v1"
    Else
         strErr = strErr & ws.Name & "_v1" & vbNewLine
    End If
Set ws1 = Nothing
Next
On Error GoTo 0

If Len(strErr) > 0 Then MsgBox strErr, vbOKOnly, "these sheets already existed"

End Sub

you can simply use onBackPressed();

or if you are using fragment you can use getActivity().onBackPressed()

You can use GUI to add these gradle command line flags from

File > Settings > Build, Execution, Deployment > Compiler

For MacOS user, it's here

Android Studio > Preferences > Build, Execution, Deployment > Compiler

like this (add --stacktrace or --debug)

Note that the screenshot is from before 0.8.10, the option is no longer in the Compiler > Gradle section, it's now in a separate section named Compiler (Gradle-based Android Project)

you can follow these simple steps:

FIRST WAY :

first copy the SQL dump file from your local directory to the mysql container. use docker cp command

docker cp [SRC-Local path to sql file] [container-name or container-id]:[DEST-path to copy to]

docker cp ./data.sql mysql-container:/home

and then execute the mysql-container using (NOTE: in case you are using alpine version you need to replace bash with sh in the given below command.)

docker exec -it -u root mysql-container bash

and then you can simply import this SQL dump file.

mysql [DB_NAME] < [SQL dump file path]

mysql movie_db < /home/data.sql

SECOND WAY : SIMPLE

docker cp ./data.sql mysql-container:/docker-entrypoint-initdb.d/

As mentioned in the mysql Docker hub official page.

Whenever a container starts for the first time, a new database is created with the specified name in MYSQL_DATABASE variable - which you can pass by setting up the environment variable see here how to set environment variables

By default container will execute files with extensions .sh, .sql and .sql.gz that are found in /docker-entrypoint-initdb.d folder. Files will be executed in alphabetical order. this way your SQL files will be imported by default to the database specified by the MYSQL_DATABASE variable.

For the sake of bandwidth saving, we shouldn't include <div> for each of <label> and <input> pair

This solution may serve you better and may increase readability

<div class="form">
            <label for="product_name">Name</label>
            <input id="product_name" name="product[name]" size="30" type="text" value="4">
            <label for="product_stock">Stock</label>
            <input id="product_stock" name="product[stock]" size="30" type="text" value="-1">
            <label for="price_amount">Amount</label>
            <input id="price_amount" name="price[amount]" size="30" type="text" value="6.0">
</div>

The css for above form would be

.form > label
{
  float: left;
  clear: right;
}

.form > input
{
  float: right;
}

I believe the output would be as following:

Use the php's OR (||) logical operator for php isset() with multiple operator e.g

if (isset($_POST['room']) || ($_POST['cottage']) || ($_POST['villa'])) {

}

To AutoComplete TextBox Control in C#.net windows application using 
wamp mysql database...

here is my code..

AutoComplete();

write this **AutoComplete();** text in form-load event..

private void Autocomplete()
    {
        try
        {
            MySqlConnection cn = new MySqlConnection("server=localhost;
database=databasename;user id=root;password=;charset=utf8;");
            cn.Open();
            MySqlCommand cmd = new MySqlCommand("SELECT distinct Column_Name
     FROM table_Name", cn);
            DataSet ds = new DataSet();
            MySqlDataAdapter da = new MySqlDataAdapter(cmd);
            da.Fill(ds, "table_Name");
            AutoCompleteStringCollection col = new   
            AutoCompleteStringCollection();
            int i = 0;
            for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
            {
                col.Add(ds.Tables[0].Rows[i]["Column_Name"].ToString());

            }
            textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
            textBox1.AutoCompleteCustomSource = col;
            textBox1.AutoCompleteMode = AutoCompleteMode.Suggest;
            cn.Close();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK,
       MessageBoxIcon.Error);
        }
    }

Just use the function for parsing a CSV file

http://php.net/manual/en/function.fgetcsv.php

$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
    echo "<p> $num fields in line $row: <br /></p>\n";
    $row++;
    for ($c=0; $c < $num; $c++) {
        echo $data[$c] . "<br />\n";
    }
  }
  fclose($handle);
}

Instead of changing the ticks, why not change the units instead? Make a separate array X of x-values whose units are in nm. This way, when you plot the data it is already in the correct format! Just make sure you add a xlabel to indicate the units (which should always be done anyways).

from pylab import *

# Generate random test data in your range
N = 200
epsilon = 10**(-9.0)
X = epsilon*(50*random(N) + 1)
Y = random(N)

# X2 now has the "units" of nanometers by scaling X
X2 = (1/epsilon) * X

subplot(121)
scatter(X,Y)
xlim(epsilon,50*epsilon)
xlabel("meters")

subplot(122)
scatter(X2,Y)
xlim(1, 50)
xlabel("nanometers")

show()

As GvS said, but I also find it useful to use strongly typed views so that I can write something like

@Html.Partial(MVC.Student.Index(), model)

without magic strings.

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

What you need is a jQuery UI Datepicker

Check out the demo and the source code.

Declare separate functions in the <head> section and invoke those in your onClick method. If you have lots you could use a naming scheme that numbers them, or pass an integer in in your onClicks and have a big fat switch statement in the function.

You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.

var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type   = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);

<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>

Like this?

 System.out.println(Name + " " + Income);

You can post axios data by using FormData() like:

var bodyFormData = new FormData();

And then add the fields to the form you want to send:

bodyFormData.append('userName', 'Fred');

If you are uploading images, you may want to use .append

bodyFormData.append('image', imageFile); 

And then you can use axios post method (You can amend it accordingly)

axios({
  method: "post",
  url: "myurl",
  data: bodyFormData,
  headers: { "Content-Type": "multipart/form-data" },
})
  .then(function (response) {
    //handle success
    console.log(response);
  })
  .catch(function (response) {
    //handle error
    console.log(response);
  });

Related GitHub issue:

Can't get a .post with 'Content-Type': 'multipart/form-data' to work @ axios/axios

According to pywin32 github you must run

    pip install pywin32

and after that, you must run

I know I'm reviving an old thread, but I just had this problem and this was the only way to solve it.

tl;dr – be patient

I ended up here because I was seeing blank images served from a https site. The problem was quite a different one though:

When content is shared for the first time, the Facebook crawler will scrape and cache the metadata from the URL shared. The crawler has to see an image at least once before it can be rendered. This means that the first person who shares a piece of content won't see a rendered image

[https://developers.facebook.com/docs/sharing/best-practices/#precaching]

While testing, it took facebook around 10 minutes to finally show the rendered image. So while I was scratching my head and throwing random og tags at facebook (and suspecting the https problem mentioned here), all I had to do was wait.

As this might really stop people from sharing your links for the first time, FB suggests two ways to circumvent this behavior: a) running the OG Debugger on all your links: the image will be cached and ready for sharing after ~10 minutes or b) specifying og:image:width and og:image:height. (Read more in the above link)

Still wondering though what takes them so long ...

For a simple enum of string values (or any other type):

public static class MyEnumClass
{
    public const string 
        MyValue1 = "My value 1",
        MyValue2 = "My value 2";
}

Usage: string MyValue = MyEnumClass.MyValue1;

You can use unescapeJava from org.apache.commons.text.StringEscapeUtils like below

str = "hello\r\njava\r\nbook";
StringEscapeUtils.unescapeJava(str);

I found the similar problem and found the solution and i have blogged about how to upload the file using JSP , In that example i have used the absolute path. Note that if you want to route to some other URL based location you can put a ESB like WSO2 ESB

To answer your question literally, here's how to get the next value of a sequence without incrementing it:

SELECT
 CASE WHEN is_called THEN
   last_value + 1
 ELSE
   last_value
 END
FROM sequence_name

Obviously, it is not a good idea to use this code in practice. There is no guarantee that the next row will really have this ID. However, for debugging purposes it might be interesting to know the value of a sequence without incrementing it, and this is how you can do it.

Android recommends that you call Environment.getExternalStorageDirectory.getPath() instead of hardcoding /sdcard/ in path name. This returns the primary shared/external storage directory. So, if storage is emulated, this will return /storage/emulated/0. If you explore the device storage with a file explorer, the said directory will be /mnt/sdcard (confirmed on Xperia Z2 running Android 6).

Most opensource projects use GetText for this purpose. I don't know how and if it's ever been used on a .Net project before.

I have Wondows 7 64 bit (MacBook Pro), installed both Java JDK x86 and x64 with JAVA_HOME pointing at x32 during installation of Android SDK, later after installation JAVA_HOME pointing at x64.

My problem was that Android SDK manager didn't launch, cmd window just flashes for a second and that's it. Like many others looked around and tried many suggestions with no juice!

My solution was in adding bin the JAVA_HOME path:

C:\Program Files\Java\jdk1.7.0_09\bin

instead of what I entered for the start:

C:\Program Files\Java\jdk1.7.0_09

Hope this helps others.... good luck!

Avoid async void. Have your methods return Task instead of void. Then you can await them.

Like this:

private async Task RequestToSendOutputReport(List<byte[]> byteArrays)
{
    foreach (byte[] b in byteArrays)
    {
        while (condition)
        {
            // we'll typically execute this code many times until the condition is no longer met
            Task t = SendOutputReportViaInterruptTransfer();
            await t;
        }

        // read some data from device; we need to wait for this to return
        await RequestToGetInputReport();
    }
}

private async Task RequestToGetInputReport()
{
    // lots of code prior to this
    int bytesRead = await GetInputReportViaInterruptTransfer();
}

This should do it:

sed -e s/deletethis//g -i *
sed -e "s/deletethis//g" -i.backup *
sed -e "s/deletethis//g" -i .backup *

it will replace all occurrences of "deletethis" with "" (nothing) in all files (*), editing them in place.

In the second form the pattern can be edited a little safer, and it makes backups of any modified files, by suffixing them with ".backup".

The third form is the way some versions of sed like it. (e.g. Mac OS X)

man sed for more information.

Use StringBuilder's append line built-in functions:

StringBuilder sb = new StringBuilder();
sb.AppendLine("First line");
sb.AppendLine("Second line");
sb.AppendLine("Third line");

Output

First line
Second line
Third line

`realpath(dirname(__FILE__))` 

it gives you current script(the script inside which you placed this code) directory without trailing slash. this is important if you want to include other files with the result

The easiest way to do this in one command is to use which command and also need not to change the factors into character by doing this:

junk$nm[which(junk$nm=="B")]<-"b"

In the error message, instead of telling you that you can't concatenate two objects by showing their values (a string and None in this example), the Python interpreter tells you this by showing the types of the objects that you tried to concatenate. The type of every string is str while the type of the single None instance is called NoneType.

You normally do not need to concern yourself with NoneType, but in this example it is necessary to know that type(None) == NoneType.

Actually, there's an easier (built in) way of doing this:

Color.decode("#FFCCEE");

You can use toLocaleString(). This is a javascript method.

var event = new Date("01/02/1993");_x000D_
_x000D_
var options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };_x000D_
_x000D_
console.log(event.toLocaleString('en', options));_x000D_
_x000D_
// expected output: "Saturday, January 2, 1993"

Almost all formats supported. Have look on this link for more details.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString

I would suggest you use PyGame and add an event handle.

Here is the HTML:

<div class="icon">
  <span class="play">
    ::before
  </span>
</div>

Computed style on 'before' was content: "VERIFY TO WATCH";

Here is my two lines of jQuery, which use the idea of adding an extra class to specifically reference this element and then appending a style tag (with an !important tag) to changes the CSS of the sudo-element's content value:

$("span.play:eq(0)").addClass('G');

$('body').append("<style>.G:before{content:'NewText' !important}</style>");

To output an object to the console, you have to stringify the object first:

success:function(data){
     console.log(JSON.stringify(data));
}

You have your arguments to the remote add command reversed:

git remote add <NAME> <PATH>

So:

git remote add bak /home/sas/dev/apps/smx/repo/bak/ontologybackend/.git

See git remote --help for more information.

You can expose the service in two different endpoints. the SOAP one can use the binding that support SOAP e.g. basicHttpBinding, the RESTful one can use the webHttpBinding. I assume your REST service will be in JSON, in that case, you need to configure the two endpoints with the following behaviour configuration

<endpointBehaviors>
  <behavior name="jsonBehavior">
    <enableWebScript/>
  </behavior>
</endpointBehaviors>

An example of endpoint configuration in your scenario is

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="json" binding="webHttpBinding"  behaviorConfiguration="jsonBehavior" contract="ITestService"/>
  </service>
</services>

so, the service will be available at

• http://www.example.com/soap
• http://www.example.com/json

Apply [WebGet] to the operation contract to make it RESTful. e.g.

public interface ITestService
{
   [OperationContract]
   [WebGet]
   string HelloWorld(string text)
}

Note, if the REST service is not in JSON, parameters of the operations can not contain complex type.

Reply to the post for SOAP and RESTful POX(XML)

For plain old XML as return format, this is an example that would work both for SOAP and XML.

[ServiceContract(Namespace = "http://test")]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "accounts/{id}")]
    Account[] GetAccount(string id);
}

POX behavior for REST Plain Old XML

<behavior name="poxBehavior">
  <webHttp/>
</behavior>

Endpoints

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="xml" binding="webHttpBinding"  behaviorConfiguration="poxBehavior" contract="ITestService"/>
  </service>
</services>

Service will be available at

• http://www.example.com/soap
• http://www.example.com/xml

REST request try it in browser,

http://www.example.com/xml/accounts/A123

SOAP request client endpoint configuration for SOAP service after adding the service reference,

  <client>
    <endpoint address="http://www.example.com/soap" binding="basicHttpBinding"
      contract="ITestService" name="BasicHttpBinding_ITestService" />
  </client>

in C#

TestServiceClient client = new TestServiceClient();
client.GetAccount("A123");

Another way of doing it is to expose two different service contract and each one with specific configuration. This may generate some duplicates at code level, however at the end of the day, you want to make it working.

Just install the latest version from nondefault repository:

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update
$ sudo apt-get install libstdc++6-4.7-dev

A very simple Java 8 solution:

File[] directories = new File("/your/path/").listFiles(File::isDirectory);

It's equivalent to using a FileFilter (works with older Java as well):

File[] directories = new File("/your/path/").listFiles(new FileFilter() {
    @Override
    public boolean accept(File file) {
        return file.isDirectory();
    }
});

Writing Ian Purton's answer in a slightly more idiomatic way:

(1..5).each do |x|
  next if x < 2
  puts x
end

Prints:

  2
  3
  4
  5

The Standard C++11 way (if you don't care about the output format):

#include <string>

auto str = std::to_string(42.5); 

to_string is a new library function introduced in N1803 (r0), N1982 (r1) and N2408 (r2) "Simple Numeric Access". There are also the stod function to perform the reverse operation.

If you do want to have a different output format than "%f", use the snprintf or ostringstream methods as illustrated in other answers.

The code below works with Last, First M name strings. Substitute "Name" with your name string column name. Since you have a period as a final character when there is a middle initial, you would replace the 2's with 3's in each of the lines (2, 6, and 8)- and change "RIGHT(Name, 1)" to "RIGHT(Name, 2)" in line 8.

SELECT  SUBSTRING(Name, 1, CHARINDEX(',', Name) - 1) LastName ,
CASE WHEN LEFT(RIGHT(Name, 2), 1) <> ' '
     THEN LTRIM(SUBSTRING(Name, CHARINDEX(',', Name) + 1, 99))
     ELSE LEFT(LTRIM(SUBSTRING(Name, CHARINDEX(',', Name) + 1, 99)),
               LEN(LTRIM(SUBSTRING(Name, CHARINDEX(',', Name) + 1, 99)))
               - 2)
END FirstName ,
CASE WHEN LEFT(RIGHT(Name, 2), 1) = ' ' THEN RIGHT(Name, 1)
     ELSE NULL
END MiddleName

Another way to think about Return-Path vs Reply-To is to compare it to snail mail.

When you send an envelope in the mail, you specify a return address. If the recipient does not exist or refuses your mail, the postmaster returns the envelope back to the return address. For email, the return address is the Return-Path.

Inside of the envelope might be a letter and inside of the letter it may direct the recipient to "Send correspondence to example address". For email, the example address is the Reply-To.

In essence, a Postage Return Address is comparable to SMTP's Return-Path header and SMTP's Reply-To header is similar to the replying instructions contained in a letter.

Ah, the following works and does what I want:

  runtime.exclude group: "org.slf4j", module: "slf4j-log4j12"
}

It seems that an Exclude Rule only has two attributes - group and module. However, the above syntax doesn't prevent you from specifying any arbitrary property as a predicate. When trying to exclude from an individual dependency you cannot specify arbitrary properties. For example, this fails:

dependencies {
  compile ('org.springframework.data:spring-data-hadoop-core:2.0.0.M4-hadoop22') {
    exclude group: "org.slf4j", name: "slf4j-log4j12"
  }
}

with

No such property: name for class: org.gradle.api.internal.artifacts.DefaultExcludeRule

So even though you can specify a dependency with a group: and name: you can't specify an exclusion with a name:!?!

Perhaps a separate question, but what exactly is a module then? I can understand the Maven notion of groupId:artifactId:version, which I understand translates to group:name:version in Gradle. But then, how do I know what module (in gradle-speak) a particular Maven artifact belongs to?

After many months, I returned to develop an AngularJS (1.6.4) app, for which I chose Chrome (PC) and Safari (MAC) for testing during development. This code presented this Error: $injector:modulerr Module Error on IE 11.0.9600 (Windows 7, 32-bit).

Upon investigation, it became clear that error was due to forEach loop being used, just replaced all the forEach loops with normal for loops for things to work as-is...

It was basically an IE11 issue (answered here) rather than an AngularJS issue, but I want to put this reply here because the exception raised was an AngularJS exception. Hope it would help some of us out there.

similarly. don't use lambda functions... just replace ()=>{...} with good ol' function(){...}

You can try jclasslib:

https://github.com/ingokegel/jclasslib

It's nice that it can associate itself with *.class extension.

Hi all Please try this property

$( "p span" ).last().addClass( "highlight" );

Thanks

Integer x=10;
Double y = x.doubleValue();

Most people already tried to answer your questions.
If you are still debugging, have you thought about using:

Double.TryParse(String, Double);

This will help you in determining what is wrong in each of the string first before you do the actual parsing.
If you have a culture-related problem, you might consider using:

Double.TryParse(String, NumberStyles, IFormatProvider, Double);

This http://msdn.microsoft.com/en-us/library/system.double.tryparse.aspx has a really good example on how to use them.

If you need a long, Int64.TryParse is also available: http://msdn.microsoft.com/en-us/library/system.int64.tryparse.aspx

Hope that helps.

Most of the answers given seem to assume that all the classes we are looking to inherit from are defined by us.

But what if one of the classes is not defined by us, i.e. we cannot change what one of those classes inherits from and therefore cannot make use of the accepted answer, what happens then?

Well the answer depends on if we have at least one of the classes having been defined by us. i.e. there exists a class A among the list of classes we would like to inherit from, where A is created by us.

In addition to the already accepted answer, I propose 3 more instances of this multiple inheritance problem and possible solutions to each.

Inheritance type 1

Ok say you want a class C to extend classes, A and B, where B is a class defined somewhere else, but A is defined by us. What we can do with this is to turn A into an interface then, class C can implement A while extending B.

class A {}
class B {} // Some external class
class C {}

Turns into

interface A {}
class AImpl implements A {}
class B {} // Some external class
class C extends B implements A

Inheritance type 2

Now say you have more than two classes to inherit from, well the same idea still holds - all but one of the classes has to be defined by us. So say we want class A to inherit from the following classes, B, C, ... X where X is a class which is external to us, i.e. defined somewhere else. We apply the same idea of turning all the other classes but the last into an interface then we can have:

interface B {}
class BImpl implements B {}
interface C {}
class CImpl implements C {}
...
class X {}
class A extends X implements B, C, ...

Inheritance type 3

Finally, there is also the case where you have just a bunch of classes to inherit from, but none of them are defined by you. This is a bit trickier, but it is doable by making use of delegation. Delegation allows a class A to pretend to be some other class B but any calls on A to some public method defined in B, actually delegates that call to an object of type B and the result is returned. This makes class A what I would call a Fat class

How does this help?

Well it's simple. You create an interface which specifies the public methods within the external classes which you would like to make use of, as well as methods within the new class you are creating, then you have your new class implement that interface. That may have sounded confusing, so let me explain better.

Initially we have the following external classes B, C, D, ..., X, and we want our new class A to inherit from all those classes.

class B {
    public void foo() {}
}

class C {
    public void bar() {}
}

class D {
    public void fooFoo() {}
}

...

class X {
    public String fooBar() {}
}

Next we create an interface A which exposes the public methods that were previously in class A as well as the public methods from the above classes

interface A {
    void doSomething(); // previously defined in A
    String fooBar(); // from class X
    void fooFoo(); // from class D
    void bar(); // from class C
    void foo(); // from class B
}

Finally, we create a class AImpl which implements the interface A.

class AImpl implements A {
    // It needs instances of the other classes, so those should be
    // part of the constructor
    public AImpl(B b, C c, D d, X x) {}
    ... // define the methods within the interface
}

And there you have it! This is sort of pseudo-inheritance because an object of type A is not a strict descendant of any of the external classes we started with but rather exposes an interface which defines the same methods as in those classes.

You might ask, why we didn't just create a class that defines the methods we would like to make use of, rather than defining an interface. i.e. why didn't we just have a class A which contains the public methods from the classes we would like to inherit from? This is done in order to reduce coupling. We don't want to have classes that use A to have to depend too much on class A (because classes tend to change a lot), but rather to rely on the promise given within the interface A.

For people do not like to modify chrome's security options, we can simply start a python http server from directory which contains your local file:

python -m SimpleHTTPServer

and for python 3:

python3 -m http.server

Now you can reach any local file directly from your js code or externally with http://127.0.0.1:8000/some_file.txt

As @stevebot said, do this:

https://<bucket-name>.s3.amazonaws.com/<key>

The one important thing I would like to add is that you either have to make your bucket objects all publicly accessible OR you can add a custom policy to your bucket policy. That custom policy could allow traffic from your network IP range or a different credential.

There is an option in Postman if you download it from https://www.getpostman.com instead of the chrome store (most probably it has been introduced in the new versions and the chrome one will be updated later) not sure about the old ones.

In the settings, turn off the SSL certificate verification option

Be sure to remember to reactivate it afterwards, this is a security feature.

If you really want to use the chrome app, you could always add an exception to chrome for the url: Enter the url you would like to open in the chrome browser, you'll get a warning with a link at the bottom of the page to add an exception, which if you do, it will also allow postman to access your url. But the first option of using the postman stand-alone app is much better.

I hope this can help.

Reflector and its add-in FileDisassembler.

Reflector will allow to see the source code. FileDisassembler will allow you to convert it into a VS solution.

<?php
    $dbName = $_SERVER["DOCUMENT_ROOT"] . "products\products.mdb";
    if (!file_exists($dbName)) {
       die("Could not find database file.");
    }
    $db = new PDO("odbc:DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$dbName; Uid=; Pwd=;");

A successful connection will allow SQL commands to be executed from PHP to read or write the database. If, however, you get the error message “PDOException Could not find driver” then it’s likely that the PDO ODBC driver is not installed. Use the phpinfo() function to check your installation for references to PDO.

If an entry for PDO ODBC is not present, you will need to ensure your installation includes the PDO extension and ODBC drivers. To do so on Windows, uncomment the line extension=php_pdo_odbc.dll in php.ini, restart Apache, and then try to connect to the database again.

With the driver installed, the output from phpinfo() should include information like this:https://www.diigo.com/item/image/5kc39/hdse

the following works for me,

  mockMvc.perform(
            MockMvcRequestBuilders.post("/api/test/url")
                    .contentType(MediaType.APPLICATION_JSON)
                    .content(asJsonString(createItemForm)))
            .andExpect(status().isCreated());

  public static String asJsonString(final Object obj) {
    try {
        return new ObjectMapper().writeValueAsString(obj);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

You can also do this in Kate.

1. Open the file
2. Open the Tools menu
3. Expand the End Of Line submenu
4. Select UNIX
5. Save the file.

k old post but no one use list expression to answer :P

list =[ ['a','b'], ['a','c'], ['b','d'] ]
Search = 'c'

# return if it find in either item 0 or item 1
print [x for x,y in list if x == Search or y == Search]

# return if it find in item 1
print [x for x,y in list if y == Search]

You are looking for the SO_KEEPALIVE socket option.

The Java Socket API exposes "keep-alive" to applications via the setKeepAlive and getKeepAlive methods.

EDIT: SO_KEEPALIVE is implemented in the OS network protocol stacks without sending any "real" data. The keep-alive interval is operating system dependent, and may be tuneable via a kernel parameter.

Since no data is sent, SO_KEEPALIVE can only test the liveness of the network connection, not the liveness of the service that the socket is connected to. To test the latter, you need to implement something that involves sending messages to the server and getting a response.

Your approach is decent for a folder that only contains files, but if you are looking for a scenario that also contains subfolders then recursion is needed

Also you should capture the return value of the return to make sure you are allowed to delete the file

and include

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

in your manifest

void DeleteRecursive(File dir)
{
    Log.d("DeleteRecursive", "DELETEPREVIOUS TOP" + dir.getPath());
    if (dir.isDirectory())
    {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++)
        {
            File temp = new File(dir, children[i]);
            if (temp.isDirectory())
            {
                Log.d("DeleteRecursive", "Recursive Call" + temp.getPath());
                DeleteRecursive(temp);
            }
            else
            {
                Log.d("DeleteRecursive", "Delete File" + temp.getPath());
                boolean b = temp.delete();
                if (b == false)
                {
                    Log.d("DeleteRecursive", "DELETE FAIL");
                }
            }
        }

    }
    dir.delete();
}

 Fragment fr = new Fragment_class();
             FragmentManager fm = getFragmentManager();
            FragmentTransaction fragmentTransaction = fm.beginTransaction();
            fragmentTransaction.add(R.id.viewpagerId, fr);
            fragmentTransaction.commit();

Just to be precise, R.id.viewpagerId is cretaed in your current class layout, upon calling, the new fragment automatically gets infiltrated.

You will get useful information from here.

In ES6, the includes() method is used to determine whether one string may be found within another string, returning true or false as appropriate.

var str = 'To be, or not to be, that is the question.';

console.log(str.includes('To be'));       // true
console.log(str.includes('question'));    // true
console.log(str.includes('nonexistent')); // false

Here is jsperf between

var ret = str.includes('one');

And

var ret = (str.indexOf('one') !== -1);

As the result shown in jsperf, it seems both of them perform well.

var rates = document.getElementById('rates').value;

cannot get values of a radio button like that instead use

rate_value = document.getElementById('r1').value;

Try

location ~ ^/(first/location|second/location)/ {
  ...
}

The ~ means to use a regular expression for the url. The ^ means to check from the first character. This will look for a / followed by either of the locations and then another /.

Here is an example:

MySqlConnection con = new MySqlConnection(
    "Server=ServerName;Database=DataBaseName;UID=username;Password=password");

MySqlCommand cmd = new MySqlCommand(
    " INSERT Into Test (lat, long) VALUES ('"+OSGconv.deciLat+"','"+
    OSGconv.deciLon+"')", con);

con.Open();
cmd.ExecuteNonQuery();
con.Close();

using conditional expressions for conciseness for python >= 2.5

def prenext(l,v) : 
   i=l.index(v)
   return l[i-1] if i>0 else None,l[i+1] if i<len(l)-1 else None


# example
x=range(10)
prenext(x,3)
>>> (2,4)
prenext(x,0)
>>> (None,2)
prenext(x,9)
>>> (8,None)

I use this on a daily basis to show history with files that changed:

git log --stat --pretty=short --graph

To keep it short, add an alias in your .gitconfig by doing:

git config --global alias.ls 'log --stat --pretty=short --graph'

In python, it's called slicing. Here is an example of python's slice notation:

>>> list1 = ['a','b','c','d','e','f','g','h', 'i', 'j', 'k', 'l']
>>> print list1[:5]
['a', 'b', 'c', 'd', 'e']
>>> print list1[-7:]
['f', 'g', 'h', 'i', 'j', 'k', 'l']

Note how you can slice either positively or negatively. When you use a negative number, it means we slice from right to left.

Assuming y, m, d are all int, how about:

CAST(CAST(y AS varchar) + '-' + CAST(m AS varchar) + '-' + CAST(d AS varchar) AS DATETIME)

Please see my other answer for SQL Server 2012 and above

Thanks to Dart's factory constructors, it's easy to build a singleton:

class Singleton {
  static final Singleton _singleton = Singleton._internal();

  factory Singleton() {
    return _singleton;
  }

  Singleton._internal();
}

You can construct it like this

main() {
  var s1 = Singleton();
  var s2 = Singleton();
  print(identical(s1, s2));  // true
  print(s1 == s2);           // true
}

TLDR Answer

Given an email address like...

[email protected]

The length limits are as follows:

• Entire Email Address (aka: "The Path"): i.e., [email protected] -- 256 characters maximum.
• Local-Part: i.e., me -- 64 character maximum.
• Domain: i.e., example.com -- 254 characters maximum.

Source

SMTP originally defined what a path was in RFC821, published August 1982, which is an official Internet Standard (most RFC's are only proposals). To quote it...

...a reverse-path, specifies who the mail is from.

...a forward-path, which specifies who the mail is to.

RFC2821, published in April 2001, is the Obsoleted Standard that defined our present maximum values for local-parts, domains, and paths. A new Draft Standard, RFC5321, published in October 2008, keeps the same limits. In between these two dates, RFC3696 was published, on February 2004. It mistakenly cites the maximum email address limit as 320-characters, but this document is "Informational" only, and states: "This memo provides information for the Internet community. It does not specify an Internet standard of any kind." So, we can disregard it.

To quote RFC2821, the modern, accepted standard as confirmed in RFC5321...

4.5.3.1.1. Local-part

The maximum total length of a user name or other local-part is 64 characters.

4.5.3.1.2. Domain

The maximum total length of a domain name or number is 255 characters.

4.5.3.1.3. Path

The maximum total length of a reverse-path or forward-path is 256 characters (including the punctuation and element separators).

You'll notice that I indicate a domain maximum of 254 and the RFC indicates a domain maximum of 255. It's a matter of simple arithmetic. A 255-character domain, plus the "@" sign, is a 256-character path, which is the max path length. An empty or blank name is invalid, though, so the domain actually has a maximum of 254.

I got this error when running dotnet publish while connected to the company VPN. Once I disconnected from the VPN, it worked.

Matplotlib can handle directly and transparently jpg if you have installed PIL. You don't need to call it, it will do it by itself. If Python cannot find PIL, it will raise an error.

jQuery addClass()

I've found one difference between the two constructions that bit me pretty hard.

Let's say I have:

function MyClass(){
  this.property1=[];
  this.property2=new Array();
};
var MyObject1=new MyClass();
var MyObject2=new MyClass();

In real life, if I do this:

MyObject1.property1.push('a');
MyObject1.property2.push('b');
MyObject2.property1.push('c');
MyObject2.property2.push('d');

What I end up with is this:

MyObject1.property1=['a','c']
MyObject1.property2=['b']
MyObject2.property1=['a','c']
MyObject2.property2=['d']

I don't know what the language specification says is supposed to happen, but if I want my two objects to have unique property arrays in my objects, I have to use new Array().

Git lets you ignore those files by assuming they are unchanged. This is done by running the git update-index --assume-unchanged path/to/file.txt command. Once marking a file as such, git will completely ignore any changes on that file; they will not show up when running git status or git diff, nor will they ever be committed.

(From https://help.github.com/articles/ignoring-files)

Hence, not deleting it, but ignoring changes to it forever. I think this only works locally, so co-workers can still see changes to it unless they run the same command as above. (Still need to verify this though.)

Note: This isn't answering the question directly, but is based on follow up questions in the comments of the other answers.

Make sure that your sas.png is marked as Build Action: Content and Copy To Output Directory: Copy Always in its Visual Studio Properties...

I think the C# source code goes like this...

Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;

and XAML should be

EDIT

Dynamically I think XAML would provide best way to load Images ...

where image.DataContext is string path.

MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";

Now as you set a different data context, Image would be automatically loaded at runtime.

Using Authorize attribute seems more convenient and feels more 'MVC way'. As for technical advantages there are some.

One scenario that comes to my mind is when you're using output caching in your app. Authorize attribute handles that well.

Another would be extensibility. The Authorize attribute is just basic out of the box filter, but you can override its methods and do some pre-authorize actions like logging etc. I'm not sure how you would do that through configuration.

You can do it this way:

=IF(E9>21,"Text 1",IF(AND(E9>=5,E9<=21),"Test 2","Text 3"))

Note I assume you meant >= and <= here since your description skipped the values 5 and 21, but you can adjust these inequalities as needed.

Or you can do it this way:

=IF(E9>21,"Text 1",IF(E9<5,"Text 3","Text 2"))

Another way to do this:

1. Put your prefix in one column say column A in excel
2. Put the values to which you want to add prefix in another column say column B in excel
3. In Column C, use this formula;

"C1=A1&B1"

4. Copy all the values in column C and paste it again in the same selection but as values only.

In Swift 4:

let formatString = "12345"
if let number = Decimal(string:formatString){

    print("String contains only number")
}
else{
    print("String doesn't contains only number")
}

You should be able to do this with JavaScript:

<input type="button" value="Click Me!" onclick="submitForms()" />

If your forms have IDs:

submitForms = function(){
    document.getElementById("form1").submit();
    document.getElementById("form2").submit();
}

If your forms don't have IDs but have names:

submitForms = function(){
    document.forms["form1"].submit();
    document.forms["form2"].submit();
}

You can use the DateTime.Parse method to get a DateTime object and then check its Month property. Do something like this:

int month = DateTime.Parse("1." + monthName + " 2008").Month;

The trick is to build a valid date to create a DateTime object.

del c:\destination\*.* /s /q worked for me. I hope that works for you as well.

Note the require-dev (root-only) !

which means that the require-dev section is only valid when your package is the root of the entire project. I.e. if you run composer update from your package folder.

If you develop a plugin for some main project, that has it's own composer.json, then your require-dev section will be completely ignored! If you need your developement dependencies, you have to move your require-dev to composer.json in main project.

I tried many ways to solve this problem, this one works for me.

Install SnapPea on your PC. SnapPea

Plug your phone in USB Debugging mode and open SnapPea, a authorization dialog will show on your phone. The Dialog shows on the phone

Hope it helps.

This error occurs on the server side when the client closed the socket connection before the response could be returned over the socket. In a web app scenario not all of these are dangerous, since they can be created manually. For example, by quitting the browser before the reponse was retrieved.

You print the queryset's query attribute.

>>> queryset = MyModel.objects.all()
>>> print(queryset.query)
SELECT "myapp_mymodel"."id", ... FROM "myapp_mymodel"

A good reason, which you have sort of touched on, is that once the CSRF cookie has been received, it is then available for use throughout the application in client script for use in both regular forms and AJAX POSTs. This will make sense in a JavaScript heavy application such as one employed by AngularJS (using AngularJS doesn't require that the application will be a single page app, so it would be useful where state needs to flow between different page requests where the CSRF value cannot normally persist in the browser).

Consider the following scenarios and processes in a typical application for some pros and cons of each approach you describe. These are based on the Synchronizer Token Pattern.

Request Body Approach

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it to a hidden field.
5. User submits form.
6. Server checks hidden field matches session stored token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Cookie can actually be HTTP Only.

Disadvantages:

• All forms must output the hidden field in HTML.
• Any AJAX POSTs must also include the value.
• The page must know in advance that it requires the CSRF token so it can include it in the page content so all pages must contain the token value somewhere, which could make it time consuming to implement for a large site.

Custom HTTP Header (downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form (token is sent via hidden field).
7. Server checks hidden field matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work without an AJAX request to get the header value.
• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CSRF token, so it will mean an extra round trip each time.
• Might as well have simply output the token to the page which would save the extra request.

Custom HTTP Header (upstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it in the page content somewhere.
5. User submits form via AJAX (token is sent via header).
6. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must include the header.

Custom HTTP Header (upstream & downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form via AJAX (token is sent via header) .
7. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CRSF token, so it will mean an extra round trip each time.

Set-Cookie

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Server generates CSRF token, stores it against the user session and outputs it to a cookie.
5. User submits form via AJAX or via HTML form.
6. Server checks custom header (or hidden form field) matches session stored token.
7. Cookie is available in browser for use in additional AJAX and form requests without additional requests to server to retrieve the CSRF token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Doesn't necessarily require an AJAX request to get the cookie value. Any HTTP request can retrieve it and it can be appended to all forms/AJAX requests via JavaScript.
• Once the CSRF token has been retrieved, as it is stored in a cookie the value can be reused without additional requests.

Disadvantages:

• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The cookie will be submitted for every request (i.e. all GETs for images, CSS, JS, etc, that are not involved in the CSRF process) increasing request size.
• Cookie cannot be HTTP Only.

So the cookie approach is fairly dynamic offering an easy way to retrieve the cookie value (any HTTP request) and to use it (JS can add the value to any form automatically and it can be employed in AJAX requests either as a header or as a form value). Once the CSRF token has been received for the session, there is no need to regenerate it as an attacker employing a CSRF exploit has no method of retrieving this token. If a malicious user tries to read the user's CSRF token in any of the above methods then this will be prevented by the Same Origin Policy. If a malicious user tries to retrieve the CSRF token server side (e.g. via curl) then this token will not be associated to the same user account as the victim's auth session cookie will be missing from the request (it would be the attacker's - therefore it won't be associated server side with the victim's session).

As well as the Synchronizer Token Pattern there is also the Double Submit Cookie CSRF prevention method, which of course uses cookies to store a type of CSRF token. This is easier to implement as it does not require any server side state for the CSRF token. The CSRF token in fact could be the standard authentication cookie when using this method, and this value is submitted via cookies as usual with the request, but the value is also repeated in either a hidden field or header, of which an attacker cannot replicate as they cannot read the value in the first place. It would be recommended to choose another cookie however, other than the authentication cookie so that the authentication cookie can be secured by being marked HttpOnly. So this is another common reason why you'd find CSRF prevention using a cookie based method.

Assign after the EXEC token:

DECLARE @returnValue INT

EXEC @returnValue = SP_One

I'd like to present a compact solution using a call by reference (yes, "batch" has pointers too!) to a function, and a "subfunction":

  @ECHO OFF
  SETLOCAL ENABLEDELAYEDEXPANSION

  SET /p NAME=- NAME ? 
  ECHO "%NAME%"
  CALL :TRIM NAME
  ECHO "%NAME%"
  GOTO :EOF

  :TRIM
  SetLocal EnableDelayedExpansion
  Call :TRIMSUB %%%1%%
  EndLocal & set %1=%tempvar%
  GOTO :EOF

  :TRIMSUB
  set tempvar=%*
  GOTO :EOF

Another way (Using Formulas in VBA). I guess this is the shortest VBA code as well?

Sub Sample()
    Dim ws As Worksheet
    Dim lRow As Long

    Set ws = ThisWorkbook.Sheets("Sheet1")

    With ws
        lRow = .Range("A" & .Rows.Count).End(xlUp).Row

        .Range("B1:B" & lRow).Formula = "=If(A1<>"""",""My Text"","""")"
        .Range("B1:B" & lRow).Value = .Range("B1:B" & lRow).Value
    End With
End Sub

this referes to the object the onclick method belongs to. So inside func this would be the DOM node of the a element and this.innerText would be here.

If the list is of type system.collections.generic you can use the "CopyTo" method available to copy elements of your array to other sub arrays. You specify the start element and number of elements to copy.

You could also make 3 clones of your original list and use the "RemoveRange" on each list to shrink the list to the size you want.

Or just create a helper method to do it for you.

SQL Server does not track the order of inserted rows, so there is no reliable way to get that information given your current table structure. Even if employee_id is an IDENTITY column, it is not 100% foolproof to rely on that for order of insertion (since you can fill gaps and even create duplicate ID values using SET IDENTITY_INSERT ON). If employee_id is an IDENTITY column and you are sure that rows aren't manually inserted out of order, you should be able to use this variation of your query to select the data in sequence, newest first:

SELECT 
   ROW_NUMBER() OVER (ORDER BY EMPLOYEE_ID DESC) AS ID, 
   EMPLOYEE_ID,
   EMPLOYEE_NAME 
FROM dbo.CSBCA1_5_FPCIC_2012_EES207201222743
ORDER BY ID;

You can make a change to your table to track this information for new rows, but you won't be able to derive it for your existing data (they will all me marked as inserted at the time you make this change).

ALTER TABLE dbo.CSBCA1_5_FPCIC_2012_EES207201222743 
-- wow, who named this?
  ADD CreatedDate DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP;

Note that this may break existing code that just does INSERT INTO dbo.whatever SELECT/VALUES() - e.g. you may have to revisit your code and define a proper, explicit column list.

I had to add extension=php_openssl.dll to my php.ini file located in xampp/php/php.ini. Somehow it was not there, after adding it and restarting Apache everything was working fine.

Make use of $"string".

In this example, it would be,

dbload=$"load data local infile \"'gfpoint.csv'\" into table $dbtable FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY \"'\n'\" IGNORE 1 LINES"

Note(from the man page):

A double-quoted string preceded by a dollar sign ($"string") will cause the string to be translated according to the current locale. If the current locale is C or POSIX, the dollar sign is ignored. If the string is translated and replaced, the replacement is double-quoted.

try this:

.button input, .button a {
//css here
}

That will apply the style to all a tags nested inside of <p class="button"></p>

Moving the state inside the constructor function worked for me:

...
class MyComponent extends Component {
  constructor(man) {
    super(man)
    this.state = {}
  }
}
...

Good Luck...

I decided to share my solution, because although many answers provided here were helpful, I still had this problem. In my case, I am using JSF 2.3, jdk10, jee8, cdi 2.0 for my new project and I did run my app on wildfly 12, starting server with parameter standalone.sh -Dee8.preview.mode=true as recommended on wildfly website. The problem with "bean resolved to null” disappeared after downloading wildfly 13. Uploading exactly the same war to wildfly 13 made it all work.

This sample in VB.NET reads all extended properties:

Sub Main()
        Dim arrHeaders(35)

        Dim shell As New Shell32.Shell
        Dim objFolder As Shell32.Folder

        objFolder = shell.NameSpace("C:\tmp")

        For i = 0 To 34
            arrHeaders(i) = objFolder.GetDetailsOf(objFolder.Items, i)
        Next
        For Each strFileName In objfolder.Items
            For i = 0 To 34
                Console.WriteLine(i & vbTab & arrHeaders(i) & ": " & objfolder.GetDetailsOf(strFileName, i))
            Next
        Next

    End Sub

You have to add a reference to Microsoft Shell Controls and Automation from the COM tab of the References dialog.

You can use relative path to mount the volume to container:

docker run -v `pwd`/certs:/container/path/to/certs ...

Note the back tick on the pwd which give you the present working directory. It assumes you have the certs folder in current directory that the docker run is executed. Kinda great for local development and keep the certs folder visible to your project.

Basically, The reason behind these type of error is eventually you are trying to delete a tupple which has primary key (root table) & that primary key is used in child table as a foreign key. In this scenario in order to delete parent table data you have to remove child table data (in which foreign key is used). Thanks

Remove obj and just do this inside your for loop:

arr.push(i);

Also, the i < yearEnd condition will not include the final year, so change it to i <= yearEnd.

I removed C:\ProgramData\Oracle\Java\javapath from my path, and it worked for me.

But make sure you include x64 JDK and JRE addresses in your path.

there are 2 main methods to backup a svn server, first is hotcopy that will create a copy of your repository files, the main problem with this approach is that it saves data about the underlying file system, so you may have some difficulties trying to repostore this kind of backup in another svn server kind or another machine. there is another type of backup called dump, this backup wont save any information of the underlying file system and its potable to any kind of SVN server based in tigiris.org subversion.

about the backup tool you can use the svnadmin tool(it is able to do hotcopy and dump) from the command prompt, this console resides in the same directory where your svn server lives or you can google for svn backup tools.

my recommendation is that you do both kinds of backups and get them out of the office to your email acount, amazon s3 service, ftp, or azure services, that way you will have a securityy backup without having to host the svn server somewhere out of your office.

SELECT CAST(FLOOR(CAST(GETDATE() AS float)) as datetime)

or

SELECT CONVERT(datetime,FLOOR(CONVERT(float,GETDATE())))

In my case, I forgot to set the "http://" in my config files (can be found in C: \Users \ [USERNAME] \ .npmrc) proxy adresses. So instead of having

proxy=http://[IPADDRESS]:[PORTNUMBER]
https-proxy=http://[IPADDRESS]:[PORTNUMBER]

I had

proxy=[IPADDRESS]:[PORTNUMBER]
https-proxy=[IPADDRESS]:[PORTNUMBER]

Which of course did not work, but the error messages didnt help much either...

this work for me on galaxy note its show contacts, file managers installed on device, gallery, music player

private void openFile(Int  CODE) {
    Intent i = new Intent(Intent.ACTION_GET_CONTENT);
    i.setType("*/*");
    startActivityForResult(intent, CODE);
}

here get path in onActivityResult of activity.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     String Fpath = data.getDataString();
    // do somthing...
    super.onActivityResult(requestCode, resultCode, data);

}

The lmplot function returns a FacetGrid instance. This object has a method called set, to which you can pass key=value pairs and they will be set on each Axes object in the grid.

Secondly, you can set only one side of an Axes limit in matplotlib by passing None for the value you want to remain as the default.

Putting these together, we have:

g = sns.lmplot('X', 'Y', df, col='Z', sharex=False, sharey=False)
g.set(ylim=(0, None))

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

    select 
    t1.Count_1,t2.Count_2
    from 
(SELECT count(1) as Count_1 FROM tab1) as t1, 
(SELECT count(1) as Count_2 FROM tab2) as t2

We can add additional columns to DataFrame directly with below steps:

from pyspark.sql.functions import when
df = spark.createDataFrame([["amit", 30], ["rohit", 45], ["sameer", 50]], ["name", "age"])
df = df.withColumn("profile", when(df.age >= 40, "Senior").otherwise("Executive"))
df.show()

This happens because in r6 it shows an error when you try to extend private styles.

Refer to this link

You can do it on a per file basis. Use the path attribute to include the filename

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <location path="YourFileNameHere.xml">
        <system.webServer>
            <staticContent>
                <clientCache cacheControlMode="DisableCache" />
            </staticContent>
        </system.webServer>
    </location>
</configuration>

Standing on the shoulders of charles-clayton and @vikas-gautam, I added the string test which is needed if a column has strings as in OP.

return isNaN(a-b) ? (a === b) ? 0 : (a < b) ? -1 : 1 : a-b  ;

The test isNaN(a-b) determines if the strings cannot be coerced to numbers. If they can then the a-b test is valid.

Note that sorting a column of mixed types will always give an entertaining result as the strict equality test (a === b) will always return false. See MDN here

This is the full script with Logger test - using Google Apps Script.

function testSort(){

function sortByCol(arr, colIndex){
    arr.sort(sortFunction);
    function sortFunction(a, b) {
        a = a[colIndex];
        b = b[colIndex];
       return isNaN(a-b) ? (a === b) ? 0 : (a < b) ? -1 : 1 : a-b  ;  // test if text string - ie cannot be coerced to numbers.
       // Note that sorting a column of mixed types will always give an entertaining result as the strict equality test will always return false
       // see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Equality_comparisons_and_sameness

Another modification:

function update() {
  $.get("response.php", function(data) {
    $("#some_div").html(data);
    window.setTimeout(update, 10000);
  });
}

The difference with this is that it waits 10 seconds AFTER the ajax call is one. So really the time between refreshes is 10 seconds + length of ajax call. The benefit of this is if your server takes longer than 10 seconds to respond, you don't get two (and eventually, many) simultaneous AJAX calls happening.

Also, if the server fails to respond, it won't keep trying.

I've used a similar method in the past using .ajax to handle even more complex behaviour:

function update() {
  $("#notice_div").html('Loading..'); 
  $.ajax({
    type: 'GET',
    url: 'response.php',
    timeout: 2000,
    success: function(data) {
      $("#some_div").html(data);
      $("#notice_div").html(''); 
      window.setTimeout(update, 10000);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      $("#notice_div").html('Timeout contacting server..');
      window.setTimeout(update, 60000);
    }
}

This shows a loading message while loading (put an animated gif in there for typical "web 2.0" style). If the server times out (in this case takes longer than 2s) or any other kind of error happens, it shows an error, and it waits for 60 seconds before contacting the server again.

This can be especially beneficial when doing fast updates with a larger number of users, where you don't want everyone to suddenly cripple a lagging server with requests that are all just timing out anyways.

The most simple way to do it without using javascript is using required=""

<input type="text" ID="txtName"  Width="165px" required=""/>

This cross-browser lib seems safer - just zoom and moz-transform won't cover as many browsers as jquery.transform2d's scale().

http://louisremi.github.io/jquery.transform.js/

For example

$('#div').css({ transform: 'scale(.5)' });

Update

OK - I see people are voting this down without an explanation. The other answer here won't work in old Safari (people running Tiger), and it won't work consistently in some older browsers - that is, it does scale things but it does so in a way that's either very pixellated or shifts the position of the element in a way that doesn't match other browsers.

Or just look at this question, which this one is likely just a dupe of:

"I tried to figure out, why exactly we need Observer and Observable"

As previous answers already stated, they provide means of subscribing an observer to receive automatic notifications of an observable.

One example application where this may be useful is in data binding, let's say you have some UI that edits some data, and you want the UI to react when the data is updated, you can make your data observable, and subscribe your UI components to the data

Knockout.js is a MVVM javascript framework that has a great getting started tutorial, to see more observables in action I really recommend going through the tutorial. http://learn.knockoutjs.com/

I also found this article in Visual Studio 2008 start page (The Observer Pattern is the foundation of Model View Controller (MVC) development) http://visualstudiomagazine.com/articles/2013/08/14/the-observer-pattern-in-net.aspx

have a look here for the full syntax: http://en.wikipedia.org/wiki/File_URI_scheme for unix-like systems it will be as @Alex said file:///your/file/here whereas for Windows systems would be file:///c|/path/to/file

Here, I solved this issue by making two functions.

1. dynamicColors() to generate random color

function dynamicColors() {
    var r = Math.floor(Math.random() * 255);
    var g = Math.floor(Math.random() * 255);
    var b = Math.floor(Math.random() * 255);
    return "rgba(" + r + "," + g + "," + b + ", 0.5)";
}

2. poolColors() to create array of colors

function poolColors(a) {
    var pool = [];
    for(i = 0; i < a; i++) {
        pool.push(dynamicColors());
    }
    return pool;
}

Then, just pass it

datasets: [{
    data: arrData,
    backgroundColor: poolColors(arrData.length),
    borderColor: poolColors(arrData.length),
    borderWidth: 1
}]

I think this question needs an updated answer, because both PostgreSQL and SQLDeveloper have been updated several times since it was originally asked.

I've got a PostgreSQL instance running in Azure, with SSLMODE=Require. While I've been using DBeaverCE to access that instance and generate an ER Diagram, I've gotten really familiar with SQLDeveloper, which is now at v19.4.

The instructions about downloading the latest PostgreSQL JDBC driver and where to place it are correct. What has changed, though, is where to configure your DB access.

You'll find a file $HOME/.sqldeveloper/system19.4.0.354.1759/o.jdeveloper.db.connection.19.3.0.354.1759/connections.json:

{
  "connections": [
    {
      "name": "connection-name-goes-here",
      "type": "jdbc",
      "info": {
        "customUrl": "jdbc:postgresql://your-postgresql-host:5432/DBNAME?sslmode=require",
        "hostname": "your-postgresql-host",
        "driver": "org.postgresql.Driver",
        "subtype": "SDPostgreSQL",
        "port": "5432",
        "SavePassword": "false",
        "RaptorConnectionType": "SDPostgreSQL",
        "user": "your_admin_user",
        "sslmode": "require"
      }
    }
  ]
}

You can use this connection with both Data Modeller and the admin functionality of SQLDeveloper. Specifying all the port, dbname and sslmode in the customUrl are required because SQLDeveloper isn't including the sslmode in what it sends via JDBC, so you have to construct it by hand.

Please use the following query to list the tables in your DB.

select name from sys.Tables 

In Addition, you can add a where condition, to skip system generated tables and lists only user created table by adding type ='U'

Ex : select name from sys.Tables where type ='U'

Have a look at the jQuery.scrollTo plugin. Here's a demo.

This plugin has a lot of options that go beyond what native scrollIntoView offers you. For instance, you can set the scrolling to be smooth, and then set a callback for when the scrolling finishes.

You can also have a look at all the JQuery plugins tagged with "scroll".

Ok I figured this out. For anyone else trying to do this you need:

a) heading: your heading from the hardware compass. This is in degrees east of magnetic north

b) bearing: the bearing from your location to the destination location. This is in degrees east of true north.

myLocation.bearingTo(destLocation);

c) declination: the difference between true north and magnetic north

The heading that is returned from the magnetometer + accelermometer is in degrees east of true (magnetic) north (-180 to +180) so you need to get the difference between north and magnetic north for your location. This difference is variable depending where you are on earth. You can obtain by using GeomagneticField class.

GeomagneticField geoField;

private final LocationListener locationListener = new LocationListener() {
   public void onLocationChanged(Location location) {
      geoField = new GeomagneticField(
         Double.valueOf(location.getLatitude()).floatValue(),
         Double.valueOf(location.getLongitude()).floatValue(),
         Double.valueOf(location.getAltitude()).floatValue(),
         System.currentTimeMillis()
      );
      ...
   }
}

Armed with these you calculate the angle of the arrow to draw on your map to show where you are facing in relation to your destination object rather than true north.

First adjust your heading with the declination:

heading += geoField.getDeclination();

Second, you need to offset the direction in which the phone is facing (heading) from the target destination rather than true north. This is the part that I got stuck on. The heading value returned from the compass gives you a value that describes where magnetic north is (in degrees east of true north) in relation to where the phone is pointing. So e.g. if the value is -10 you know that magnetic north is 10 degrees to your left. The bearing gives you the angle of your destination in degrees east of true north. So after you've compensated for the declination you can use the formula below to get the desired result:

heading = myBearing - (myBearing + heading); 

You'll then want to convert from degrees east of true north (-180 to +180) into normal degrees (0 to 360):

Math.round(-heading / 360 + 180)

I can't take the credit for the code though, it comes from quick and easy way to make google maps iframe embed responsive.

Good luck!

If you use

git fetch --dry-run -v <link/to/remote/git/repo>

you'll get feedback about whether it is up-to-date. So basically, you just need to add the "verbose" option to the answer given before.

I had same error, just uninstalled and installed again the numpy package, that worked!

For example, let's say that you want to create a random number between 50 and 60, you can use one of the following methods.

new Random().nextInt()%6 +55

new Random().nextInt()%6 returns a value between -5 and 5. and when you add it to 55 you can get values between 50 and 60

Second method:

Math.abs(new Random().nextInt()%11) +50

Math.abs(new Random().nextInt()%11) creates a value between 0 and 10. Later you can add 50 which in the will give you a value between 50 and 60

I am not sure did you see this list of MS SQL Modules for Node JS

Share your experience after using one if possible .

Good Luck

It might help you to understand.

import * as Rx from 'rxjs';

const subject1 = new Rx.Subject();
subject1.next(1);
subject1.subscribe(x => console.log(x)); // will print nothing -> because we subscribed after the emission and it does not hold the value.

const subject2 = new Rx.Subject();
subject2.subscribe(x => console.log(x)); // print 1 -> because the emission happend after the subscription.
subject2.next(1);

const behavSubject1 = new Rx.BehaviorSubject(1);
behavSubject1.next(2);
behavSubject1.subscribe(x => console.log(x)); // print 2 -> because it holds the value.

const behavSubject2 = new Rx.BehaviorSubject(1);
behavSubject2.subscribe(x => console.log('val:', x)); // print 1 -> default value
behavSubject2.next(2) // just because of next emission will print 2 

Noticed this is a 2-years old question, but still want to share my workaround for this particular question:

Firstly, run docker container ls -a to list all the containers you have and pinpoint the want you want to delete.

Secondly, delete the one with command docker container rm <CONTAINER ID> (If the container is currently running, you should stop it first, run docker container stop <CONTAINER ID> to gracefully stop the specified container, if it does not stop it for whatever the reason is, alternatively you can run docker container kill <CONTAINER ID> to force shutdown of the specified container).

Thirdly, remove the container by running docker container rm <CONTAINER ID>.

Lastly you can run docker image ls -a to view all the images and delete the one you want to by running docker image rm <hash>.

I know this answer is not 100% related to the question, but it might help someone.

If you want to disable the browser cache for the entire ASP.NET MVC Website, but you only want to do this TEMPORARILY, then it is better to disable the cache in your browser.

Pass it a Comparator. Fill in your desired type in place of T

Using lambdas (Java 8+):

int initialCapacity = 10;
PriorityQueue<T> pq = new PriorityQueue<>(initialCapacity, (e1, e2) -> { return e1.compareTo(e2); });

Classic way, using anonymous class:

int initialCapacity = 10;
PriorityQueue<T> pq = new PriorityQueue<>(initialCapacity, new Comparator<T> () {

    @Override
    public int compare(T e1, T e2) {
        return e1.compareTo(e2);
    }

});

To sort in reverse order, simply swap e1, e2.

This problem is usually caused by writing to a connection that had already been closed by the peer. In this case it could indicate that the user cancelled the download for example.

Install ActivePython. It includes pip, virtualenv and Distribute.

Download the Windows SDK and then go to View->Properties->Configuration Manager->Active Solution Platform->New->x64.

As astander has mentioned, you can do that with a UDF. However, for large sets using a scalar function (as oppoosed to a inline-table function) the performance will stink as the function is evaluated row-by-row. As an alternative, you could expose the same results via a stored procedure executing a fixed query with placeholders which substitutes in your parameter values.

(Here's a somewhat dated but still relevant article on row-by-row processing for scalar UDFs.)

Edit: comments re. degrading performance adjusted to make it clear this applies to scalar UDFs.

I have just used dompdf and the code was a little different but it worked.

Here it is:

require_once("./pdf/dompdf_config.inc.php");
$files = glob("./pdf/include/*.php");
foreach($files as $file) include_once($file);

$html =
      '<html><body>'.
      '<p>Put your html here, or generate it with your favourite '.
      'templating system.</p>'.
      '</body></html>';

    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    $output = $dompdf->output();
    file_put_contents('Brochure.pdf', $output);

Only difference here is that all of the files in the include directory are included.

Other than that my only suggestion would be to specify a full directory path for writing the file rather than just the filename.
