Use this as the connection string to connect to oracle db.

Just wanted to add -- apparently this can also be caused by installing Instant Client for 10, then realizing you want the full install and installing it again in a parallel directory. I don't know why this broke it.

This is an old question but Oracle's latest installers are no improvement, so I recently found myself back in this swamp, thrashing around for several days ...

My scenario was SQL Server 2016 RTM. 32-bit Oracle 12c Open Client + ODAC was eventually working fine for Visual Studio Report Designer and Integration Services designer, and also SSIS packages run through SQL Server Agent (with 32-bit option). 64-bit was working fine for Report Portal when defining and Testing an Data Source, but running the reports always gave the dreaded "ORA-12154" error.

My final solution was to switch to an EZCONNECT connection string - this avoids the TNSNAMES mess altogether. Here's a link to a detailed description, but it's basically just: host:port/sid

http://www.oracledistilled.com/oracle-database/oracle-net/using-easy-connect-ezconnect-naming-method-to-connect-to-oracle-databases/

In case it helps anyone in the future (or I get stuck on this again), here are my Oracle install steps (the full horror):

Install Oracle drivers: Oracle Client 12c (32-bit) plus ODAC.

a. Download and unzip the following files from http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-win64-download-2297732.html and http://www.oracle.com/technetwork/database/windows/downloads/utilsoft-087491.html ):

i. winnt_12102_client32.zip

ii. ODAC112040Xcopy_32bit.zip

b. Run winnt_12102_client32\client32\setup.exe. For the Installation Type, choose Admin. For the installation location enter C:\Oracle\Oracle12. Accept other defaults.

c. Start a Command Prompt “As Administrator” and change directory (cd) to your ODAC112040Xcopy_32bit folder.

d. Enter the command: install.bat all C:\Oracle\Oracle12 odac

e. Copy the tnsnames.ora file from another machine to these folders: *

i. C:\Oracle\Oracle12\network\admin *

ii. C:\Oracle\Oracle12\product\12.1.0\client_1\network\admin *

Install Oracle Client 12c (x64) plus ODAC

a. Download and unzip the following files from http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-win64-download-2297732.html and http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html ):

i. winx64_12102_client.zip

ii. ODAC121024Xcopy_x64.zip

b. Run winx64_12102_client\client\setup.exe. For the Installation Type, choose Admin. For the installation location enter C:\Oracle\Oracle12_x64. Accept other defaults.

c. Start a Command Prompt “As Administrator” and change directory (cd) to the C:\Software\Oracle Client\ODAC121024Xcopy_x64 folder.

d. Enter the command: install.bat all C:\Oracle\Oracle12_x64 odac

e. Copy the tnsnames.ora file from another machine to these folders: *

i. C:\Oracle\Oracle12_x64\network\admin *

ii. C:\Oracle\Oracle12_x64\product\12.1.0\client_1\network\admin *

* If you are going with the EZCONNECT method, then these steps are not required.

The ODAC installs are tricky and obscure - thanks to Dan English who gave me the method (detailed above) for that.

In reference to #7 in this MSDN POST , adding a registry entry worked for me. I had Vs2010, et oracle 11.0 installed.

Check for the registry key “TNS_ADMIN” at HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE. If it exists then make sure it has the right value as “Dir:\app\product\11.1.0\client_1\network\admin”. If you don’t see the key then create the key and set appropriate value as below. Regedit->HKEY_LOCAL_MACHINE->Software->Oracle->RightClick NEW->StringValue and name it TNS_ADMIN and give the value “X:\app\product\11.1.0\client_1\network\admin”

There is no way to store objects in SharedPreferences, What i did is to create a public class, put all the parameters i need and create setters and getters, i was able to access my objects,

List<T> is a specific implementation of IList<T>, which is a container that can be addressed the same way as a linear array T[] using an integer index. When you specify IList<T> as the type of the method's argument, you only specify that you need certain capabilities of the container.

For example, the interface specification does not enforce a specific data structure to be used. The implementation of List<T> happens to the same performance for accessing, deleting and adding elements as a linear array. However, you could imagine an implementation that is backed by a linked list instead, for which adding elements to the end is cheaper (constant-time) but random-access much more expensive. (Note that the .NET LinkedList<T> does not implement IList<T>.)

This example also tells you that there may be situations when you need to specify the implementation, not the interface, in the argument list: In this example, whenever you require a particular access performance characteristic. This is usually guaranteed for a specific implementation of a container (List<T> documentation: "It implements the IList<T> generic interface using an array whose size is dynamically increased as required.").

Additionally, you might want to consider exposing the least functionality you need. For example. if you don't need to change the content of the list, you should probably consider using IEnumerable<T>, which IList<T> extends.

Another option is to create a free Kiln account -- kiln round trips between git and hg with 100% metadata retention, so you can use it for a one time convert or use it to access a repository using whichever client you prefer.

Amazingly now org.json now lets you put a byte[] object directly into a json and it remains readable. you can even send the resulting object over a websocket and it will be readable on the other side. but i am not sure yet if the size of the resulting object is bigger or smaller than if you were converting your byte array to base64, it would certainly be neat if it was smaller.

It seems to be incredibly hard to measure how much space such a json object takes up in java. if your json consists merely of strings it is easily achievable by simply stringifying it but with a bytearray inside it i fear it is not as straightforward.

stringifying our json in java replaces my bytearray for a 10 character string that looks like an id. doing the same in node.js replaces our byte[] for an unquoted value reading <Buffered Array: f0 ff ff ...> the length of the latter indicates a size increase of ~300% as would be expected

Ultimately, this is not a matter of standards or best practices for markup, but rather knowing your audience and making sure your website does what you want it to do.

It's more important to consider the width of the browser viewport rather than screen resolution -- you cannot assume that every pixel on a display will be allocated to the browser (and even if it is, you have to subtract browser chrome). If you have access to analytics that report browser width (n.b. browser width, not screen resolution) then pay very close attention.

It's nice to try to accommodate the widest possible range of viewports but there are some limitations. Some challenges can be handled with CSS media types, some can't. Some can be handled with fluid layouts. But fluid layouts cannot work in all situations, depending on the type of information to be displayed, line length, reading comfort, etc. Some fluid layouts don't work in wide displays. Most break when sized below a certain width, etc.

As much as I'd personally like to design for viewports ~960 pixels and up, you can't always do it. So in some cases, it's still safest to design for viewports <=760 pixels or so (800 pixel wide display, maximized) -- though the time we can finally toss this limitation once and for all -- for the desktop at least -- is very fast approaching.

Where conversions are an issue -- and you have a fixed width layout -- you better have a darned good reason for putting anything that the user needs to click in order for the cash register to go "ka-ching" anywhere east of the 760th pixel.

Ditto for the primary navigation.

Finally, test your layout in everything you can get your hands on. Big. Small. Desktop. Handheld. The works. There's no substitute.

Well, I did this like this:

dgvReport.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None;
dgvReport.AutoResizeColumns();
dgvReport.AllowUserToResizeColumns = true;
dgvReport.AllowUserToOrderColumns = true;

in that particular order. Columns are resized (extended) AND the user can resize columns afterwards.

Personally I prefer this clean implementation:

watch: {
  myVariable: {
     handler(newVal, oldVal){  // here having access to the new and old value
       // do stuff
     },
     deep: true,
     immediate: true //  Also very important the immediate in case you need it, the callback will be called immediately after the start of the observation

  }
}

To add my 2 cents, if you want to update your data source with the new value of your Control, you need to call UpdateSource() instead of UpdateTarget():

((TextBox)sender).GetBindingExpression(ComboBox.TextProperty).UpdateSource();

Navigate to Settings > About Phone > scroll to the bottom > tap Build number seven (7) times. You'll get a short pop-up in the lower area of your display saying that you're now a developer. 2. Go back and now access the Developer options menu, check 'USB debugging' and click OK on the prompt. This Guide Might Help You : How to Enable USB Debugging in Android Phones

In testing2.php use the following code to get the name:

if ( ! empty($_POST['name'])){
    $name = $_POST['name']);
}

When you create the next page, use the value of $name to prefill the form field:

Name: <input type="text" name="name" id="name" value="<?php echo $name; ?>"><br/>

However, before doing that, be sure to use regular expressions to verify that the $name only contains valid characters, such as:

$pattern =  '/^[0-9A-Za-zÁ-Úá-úàÀÜü]+$/';//integers & letters
if (preg_match($pattern, $name) == 1){
    //continue
} else {
    //reload form with error message
}

Some currency pairs have no historical data for certain days.

Compare =GOOGLEFINANCE("CURRENCY:EURNOK", "close", DATE(2016,1,1), DATE(2016,1,12):

1/11/2016 23:58:00  9.705679083

and =GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,1), DATE(2016,1,12):

1/11/2016 23:58:00  82.50853122

So, =INDEX(GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,1)), 2, 2) gives

79.44402768

But =INDEX(GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,2)), 2, 2) gives

#N/A

Therefore, when working with currency pairs that have no exchange rates for weekends/holidays, the following formula may be used for getting the exchange rate for the first following working day:

=INDEX(GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,2), 4), 2, 2)

copy paste pl sql developer in program files x86 and program files both. if client is installed in other partition/drive then copy pl sql developer to that drive also. and run from pl sql developer folder instead of desktop shortcut.

Edit:

The above response is really not a good solution, having learned a lot about JS since I initially posted. See EndangeredMassa's answer below for the better approach to solving this problem.

In my case, I tried to open a DOS prompt and go to the MySQL bin\ directory and issue the below command:

mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini" --standalone --console

And it shows me I was missing the "C:\Program Files\MySQL\MySQL Server 5.0\Uploads" folder; I built one and problem solved.

Try using Async instead to avoid blocking the only thread you have with NodeJS. Check this example:

const util = require('util');
const fs = require('fs');
const path = require('path');
const readFileAsync = util.promisify(fs.readFile);

const readContentFile = async (filePath) => {
  // Eureka, you are using good code practices here!
  const content = await readFileAsync(path.join(__dirname, filePath), {
    encoding: 'utf8'
  })
  return content;
}

Later can use this async function with try/catch from any other function:

const anyOtherFun = async () => {
  try {
    const fileContent = await readContentFile('my-file.txt');
  } catch (err) {
    // Here you get the error when the file was not found,
    // but you also get any other error
  }
}

Happy Coding!

An int is a 32-bit integer; a long is a 64-bit integer. Which one to use depends on how large the numbers are that you expect to work with.

int and long are primitive types, while Integer and Long are objects. Primitive types are more efficient, but sometimes you need to use objects; for example, Java's collection classes can only work with objects, so if you need a list of integers you have to make it a List<Integer>, for example (you can't use int in a List directly).

Instead of checking in folder node_modules, make a package.json file for your application.

The package.json file specifies the dependencies of your application. Heroku can then tell npm to install all of those dependencies. The tutorial you linked to contains a section on package.json files.

You should be aware that you should avoid file I/O from within Linux kernel when possible. The main idea is to go "one level deeper" and call VFS level functions instead of the syscall handler directly:

Includes:

#include <linux/fs.h>
#include <asm/segment.h>
#include <asm/uaccess.h>
#include <linux/buffer_head.h>

Opening a file (similar to open):

struct file *file_open(const char *path, int flags, int rights) 
{
    struct file *filp = NULL;
    mm_segment_t oldfs;
    int err = 0;

    oldfs = get_fs();
    set_fs(get_ds());
    filp = filp_open(path, flags, rights);
    set_fs(oldfs);
    if (IS_ERR(filp)) {
        err = PTR_ERR(filp);
        return NULL;
    }
    return filp;
}

Close a file (similar to close):

void file_close(struct file *file) 
{
    filp_close(file, NULL);
}

Reading data from a file (similar to pread):

int file_read(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_read(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}   

Writing data to a file (similar to pwrite):

int file_write(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_write(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}

Syncing changes a file (similar to fsync):

int file_sync(struct file *file) 
{
    vfs_fsync(file, 0);
    return 0;
}

[Edit] Originally, I proposed using file_fsync, which is gone in newer kernel versions. Thanks to the poor guy suggesting the change, but whose change was rejected. The edit was rejected before I could review it.

In my case, this jQuery JavaScript solved the problem

jQuery(function() {
            jQuery("form.myform").submit(function(event) {
               event.preventDefault();
               return false;
            });
}

<img src="../assets/graph_selected.svg"/>

The static path is resolved by Webpack as a module dependency through loader. But for dynamic path you need to use require to resolve the path. You can then switch between images using a boolean variable & ternary expression.

<img :src="this.graph ? require( `../assets/graph_selected.svg`) 
: require( `../assets/graph_unselected.svg`) " alt="">

And of course toggle the value of the boolean through some event handler.

You could use something like a set from Programming in Lua:

function Set (list)
  local set = {}
  for _, l in ipairs(list) do set[l] = true end
  return set
end

Then you could put your list in the Set and test for membership:

local items = Set { "apple", "orange", "pear", "banana" }

if items["orange"] then
  -- do something
end

Or you could iterate over the list directly:

local items = { "apple", "orange", "pear", "banana" }

for _,v in pairs(items) do
  if v == "orange" then
    -- do something
    break
  end
end

use

=VLOOKUP(D4,F4:G9,2)

with the range F4:G9:

0   0.1
1   0.15
5   0.2
15  0.3
30  1
100 1.3

and D4 being the value in question, e.g. 18.75 -> result: 0.3

If you are working with Images only and you need mime type (e.g. for headers), then this is the fastest and most direct answer:

$file = 'path/to/image.jpg';
$image_mime = image_type_to_mime_type(exif_imagetype($file));

It will output true image mime type even if you rename your image file

Probably your item.photo is undefined if you don't have a photo attribute on item in the first place and thus undefined != ''. But if you'd put some code to show how you provide values to item, it would help.

PS: Sorry to post this as an answer (I rather think it's more of a comment), but I don't have enough reputation yet.

In addition to potame's answer, if you do want to escape using a CDATA block.

If you put your text in a CDATA block then you don't need to use escaping. In that case you can use all characters in the following range:

Note: On top of that, you're not allowed to use the ]]> character sequence. Because it would match the end of the CDATA block.

If there are still invalid characters (e.g. control characters), then probably it's better to use some kind of encoding (e.g. base64).

You can reset the counter with:

ALTER TABLE tablename AUTO_INCREMENT = 1

For InnoDB you cannot set the auto_increment value lower or equal to the highest current index. (quote from ViralPatel):

Note that you cannot reset the counter to a value less than or equal to any that have already been used. For MyISAM, if the value is less than or equal to the maximum value currently in the AUTO_INCREMENT column, the value is reset to the current maximum plus one. For InnoDB, if the value is less than the current maximum value in the column, no error occurs and the current sequence value is not changed.

See How to Reset an MySQL AutoIncrement using a MAX value from another table? on how to dynamically get an acceptable value.

Short tag are alwayes available in php. So you do not need echo the first statement in your script

example:

    $a =10;
    <?= $a;//10 
    echo "Hellow";//
    echo "Hellow";

   ?>

Suddenly you need to use for a single php script then u can use it. example:

<html>
<head>
<title></title>
</head>  
<body>
<p>hellow everybody<?= hi;?></p>
<p>hellow everybody  </p> 
<p>hellow everybody  </p>   
</body>
</html>

I went searching around for a similar question - the way I've managed to initialize a Git repository for an existing project file is this (disclaimer: this is done in Visual Studio 2013 Express, without a Team Foundation Server setup):

1. Open the project in Visual Studio.
2. Go to menu File ? Add to Source Control.

That did it for me - assuming Git is set up for you, you can go to menu View ? Team Explorer, then double click the repository for your project file, and make your initial commit (making sure to add whatever files you'd like).

<form action="" method="POST" enctype="multipart/form-data">
  Select image to upload:
  <input type="file"   name="file[]" multiple/>
  <input type="submit" name="submit" value="Upload Image" />
</form>

Using FOR Loop

<?php    
  $file_dir  = "uploads";    
  if (isset($_POST["submit"])) {

    for ($x = 0; $x < count($_FILES['file']['name']); $x++) {               

      $file_name   = $_FILES['file']['name'][$x];
      $file_tmp    = $_FILES['file']['tmp_name'][$x];

      /* location file save */
      $file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name; /* DIRECTORY_SEPARATOR = / or \ */

      if (move_uploaded_file($file_tmp, $file_target)) {                        
        echo "{$file_name} has been uploaded. <br />";                      
      } else {                      
        echo "Sorry, there was an error uploading {$file_name}.";                               
      }                 

    }               
  }    
?>

Using FOREACH Loop

<?php
  $file_dir  = "uploads";    
  if (isset($_POST["submit"])) {

    foreach ($_FILES['file']['name'] as $key => $value) {                   

      $file_name   = $_FILES['file']['name'][$key];
      $file_tmp    = $_FILES['file']['tmp_name'][$key];

      /* location file save */
      $file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name; /* DIRECTORY_SEPARATOR = / or \ */

      if (move_uploaded_file($file_tmp, $file_target)) {                        
        echo "{$file_name} has been uploaded. <br />";                      
      } else {                      
        echo "Sorry, there was an error uploading {$file_name}.";                               
      }                 

    }               
  }
?>

Something like this?

public static T ConvertValue<T>(string value)
{
    return (T)Convert.ChangeType(value, typeof(T));
}

You can then use it like this:

int val = ConvertValue<int>("42");

Edit:

You can even do this more generic and not rely on a string parameter provided the type U implements IConvertible - this means you have to specify two type parameters though:

public static T ConvertValue<T,U>(U value) where U : IConvertible
{
    return (T)Convert.ChangeType(value, typeof(T));
}

I considered catching the InvalidCastException exception that might be raised by Convert.ChangeType() - but what would you return in this case? default(T)? It seems more appropriate having the caller deal with the exception.

Looks like this is on the bottom left now as an icon with overlapping windows and the "Undock into separate window." tooltip.

in android studio if using gradle

add this to build.gradle

compile fileTree(dir: 'libs', include: ['*.jar'])

and add the jar file to libs folder

overflow:hidden 

does not always mean that the element is hidden or non existent in the DOM, it means that the overflowing chars that do not fit in the element are being trimmed. Basically it means that do not show scrollbar even if it should be showed, so in your case the link with text

Plastic Spiral Bind

could possibly be shown as "Plastic Spir..." or similar. So it is possible, that this linkText indeed is non existent.

So you can probably try:

driver.findElement(By.partialLinkText("Plastic ")).click();

or xpath:

//a[contains(@title, \"Plastic Spiral Bind\")]

In large part, pointers are arrays (in C/C++) - they are addresses in memory, and can be accessed like an array if desired (in "normal" cases).

Since they're the address of an item, they're small: they take up only the space of an address. Since they're small, sending them to a function is cheap. And then they allow that function to work on the actual item rather than a copy.

If you want to do dynamic storage allocation (such as for a linked-list), you must use pointers, because they're the only way to grab memory from the heap.

The total of 7 numbers in an array can be created as:

import java.util.*;
class Sum
{
   public static void main(String arg[])
   {
     int a[]=new int[7];
     int total=0;
     Scanner n=new Scanner(System.in);
     System.out.println("Enter the no. for total");

     for(int i=0;i<=6;i++) 
     {
       a[i]=n.nextInt();
       total=total+a[i];
      }
       System.out.println("The total is :"+total);
    }
}

When running Nginx in a Docker container, be aware that a volume mounted over the log dir defeats the purpose of creating a softlink between the log files and stdout/stderr in your Dockerfile, as described in @Boeboe 's answer.

In that case you can either create the softlink in your entrypoint (executed after volumes are mounted) or not use a volume at all (e.g. when logs are already collected by a central logging system).

F4 doesn't always bring me to this panel. Besides, it is often said that a picture is worth a thousand words.

Starting from the decoded base64 data of an OpenSSL rsa-ssh Key, i've been able to guess a format:

• 00 00 00 07: four byte length prefix (7 bytes)
• 73 73 68 2d 72 73 61: "ssh-rsa"
• 00 00 00 01: four byte length prefix (1 byte)
• 25: RSA Exponent (e): 25
• 00 00 01 00: four byte length prefix (256 bytes)

• RSA Modulus (n):

The closest validation of my theory i can find it from RFC 4253:

The "ssh-rsa" key format has the following specific encoding:

  string    "ssh-rsa"
  mpint     e
  mpint     n

Here the 'e' and 'n' parameters form the signature key blob.

But it doesn't explain the length prefixes.

From RFC3447 - Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.1:

A.1.1 RSA public key syntax

An RSA public key should be represented with the ASN.1 type RSAPublicKey:

  RSAPublicKey ::= SEQUENCE {
     modulus           INTEGER,  -- n
     publicExponent    INTEGER   -- e
  }

The fields of type RSAPublicKey have the following meanings:

• modulus is the RSA modulus n.
• publicExponent is the RSA public exponent e.

Using Microsoft's excellent (and the only real) ASN.1 documentation:

30 82 01 0a       ;SEQUENCE (0x010A bytes: 266 bytes)
|  02 82 01 01    ;INTEGER  (0x0101 bytes: 257 bytes)
|  |  00          ;leading zero because high-bit, but number is positive

|  |  63 
|  02 03          ;INTEGER (3 bytes)
|     01 00 01

giving the public key modulus and exponent:

• modulus = 0xfb1199ff0733f6e805a4fd3b36ca68...837a63
• exponent = 65,537

Update: My expanded form of this answer in another question

I'm told bbfreeze will create a single file .EXE, and is newer than py2exe.

Commenting just so people can have a solution to the intended question.

You can do what you are wanting but it isn't quite as nice as Notepad++ but it may work for small solutions decently enough.

In sublime if you hold ctrl, or mac equiv., and select the word/characters you want on a single line with the mouse and still holding ctrl go to another line and select the word/characters you want on that line it will be additive and you will build your selection. I mainly use notepadd++ as my extractor and data cleanup and sublime for actual development.

The other way is if your columns are in perfect alignment you can simply middle click on windows or option + click on mac and this enables you to select text in a square like fashion, Columns, inside the lines of text.

Here's a quick and dirty function to remove a row by index.

removeRowByIndex <- function(x, row_index) {
  nr <- nrow(x)
  if (nr < row_index) {
    print('row_index exceeds number of rows')
  } else if (row_index == 1)
  {
    return(x[2:nr, ])
  } else if (row_index == nr) {
    return(x[1:(nr - 1), ])
  } else {
    return (x[c(1:(row_index - 1), (row_index + 1):nr), ])
  }
}

It's main flaw is it the row_index argument doesn't follow the R pattern of being a vector of values. There may be other problems as I only spent a couple of minutes writing and testing it, and have only started using R in the last few weeks. Any comments and improvements on this would be very welcome!

Lots of the answers here don't honor changes of the table or are way too complicated. Using a subclass of UITableView that will properly set intrinsicContentSize is a far easier solution when using autolayout. No height constraints etc. needed.

class UIDynamicTableView: UITableView
{
    override var intrinsicContentSize: CGSize {
        self.layoutIfNeeded()
        return CGSize(width: UIViewNoIntrinsicMetric, height: self.contentSize.height)
    }

    override func reloadData() {
        super.reloadData()
        self.invalidateIntrinsicContentSize()
    }
} 

Set the class of your TableView to UIDynamicTableView in the interface builder and watch the magic as this TableView will change it's size after a call to reloadData().

To set programmatically:

setBackgroundColor(Color.TRANSPARENT);

For me, I also had to set it to Color.TRANSPARENT on the parent layout.

• If you have multiple windows open and only want to close the one that was closed use JFrame.dispose().

• If you want to close all windows and terminate the application use System.exit()

Class that will call the methods:

namespace myNamespace
{
    public class myClass
    {
        public static void voidMethodWithoutParameters()
        {
            // code here
        }
        public static string stringReturnMethodWithParameters(string param1, string param2)
        {
            // code here
            return "output";
        }
    }
}

Calling myClass static methods using Reflection:

var myClassType = Assembly.GetExecutingAssembly().GetType(GetType().Namespace + ".myClass");
                    
// calling my void Method that has no parameters.
myClassType.GetMethod("voidMethodWithoutParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, null);

// calling my string returning Method & passing to it two string parameters.
Object methodOutput = myClassType.GetMethod("stringReturnMethodWithParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, new object[] { "value1", "value1" });
Console.WriteLine(methodOutput.ToString());

Note: I don't need to instantiate an object of myClass to use it's methods, as the methods I'm using are static.

I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.

Set cn = CreateObject("ADODB.Connection")
With cn
 .Provider = "Microsoft.Jet.OLEDB.4.0"
  .ConnectionString = "Data Source=D:\test.xls " & _
  ";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
  For i = 0 To rs.Fields.Count - 1
    Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
    strNaam = rs.Fields(0).Value
  Next
  rs.MoveNext
Loop
rs.Close

There are other ways, depending on what you want to do, such as GetString (GetString Method Description).

You can use var_dump or print_r functions on Blade themplate via Controller functions :

class myController{

   public function showView(){
     return view('myView',["myController"=>$this]);
   }
   public function myprint($obj){
     echo "<pre>";
     print_r($obj);
     echo "</pre>";
   }
}

And use your blade themplate :

$myController->myprint($users);

If you use Kotlin, you can do the following:

1. On first, you should be create Interface and implemented him in your Fragment

interface RefreshData {
    fun refresh()
}

class YourFragment : Fragment(), RefreshData {
    ...
    override fun refresh() {
        //do what you want
    }
}

2. Next step is add OnPageChangeListener to your ViewPager

viewPager.addOnPageChangeListener(object : ViewPager.OnPageChangeListener {
    override fun onPageScrollStateChanged(state: Int) { }

    override fun onPageSelected(position: Int) {
        viewPagerAdapter.notifyDataSetChanged()
        viewPager.currentItem = position
    }

    override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) { }
})

3. override getItemPosition in your Adapter

override fun getItemPosition(obj: Any): Int {
    if (obj is RefreshData) {
        obj.refresh()
    }
    return super.getItemPosition(obj)
}

Either you initialize the variable to something

char retChar = 'x';

or you leave it automatically initialized, which is

char retChar = '\0';

an ascii 0, the same as

char retChar = (char) 0;

What can one initialize char values to?

Sounds undecided between automatic initialisation, which means, you have no influence, or explicit initialisation. But you cannot change the default.

Just assuming this is for a regular expression, use re.escape.

$pristine/$dirty tells you whether the user actually changed anything, while $touched/$untouched tells you whether the user has merely been there/visited.

This is really useful for validation. The reason for $dirty was always to avoid showing validation responses until the user has actually visited a certain control. But, by using only the $dirty property, the user wouldn't get validation feedback unless they actually altered the value. So, an $invalid field still wouldn't show the user a prompt if the user didn't change/interact with the value. If the user entirely ignored a required field, everything looked OK.

With Angular 1.3 and ng-touched, you can now set a particular style on a control as soon as the user has blurred, regardless of whether they actually edited the value or not.

Here's a CodePen that shows the difference in behavior.

I also put an answer there, but the article @Colonel Panic's update refers to suggests forcing TLS 1.2. In the future, when TLS 1.2 is compromised or just superceded, having your code stuck to TLS 1.2 will be considered a deficiency. Negotiation to TLS1.2 is enabled in .Net 4.6 by default. If you have the option to upgrade your source to .Net 4.6, I would highly recommend that change over forcing TLS 1.2.

If you do force TLS 1.2, strongly consider leaving some type of breadcrumb that will remove that force if you do upgrade to the 4.6 or higher framework.

Modification of great John solution, solve:

• "2 quotes" error

• space after one of piece in parameter

  WHILE @chrind > 0
  BEGIN
    SELECT @chrind = CHARINDEX(@Delim,@RepParam)
    IF @chrind  > 0
      SELECT @Piece = LEFT(@RepParam,@chrind - 1)
    ELSE
      SELECT @Piece = @RepParam
    INSERT  @Values(Param) VALUES(CAST(@Piece AS VARCHAR(300)))
    //space after one of piece in parameter: LEN(@RepParam + '1')-1
    SELECT @RepParam = RIGHT(@RepParam,LEN(@RepParam + '1')-1 - @chrind)
    IF LEN(@RepParam) = 0 BREAK
  END
  RETURN
  END
  
  

You can create a form via jQuery or in the HTML page code with an action that mimics your link href:

<a id="anchor_link" href="somepath.php">click here</a>.

var link = $('#anchor_link').attr('href');
$('body').append('<form id="new_form" action="'+link+'"></form>');
$('#new_form').submit();

First of all, wave bye-bye to those quotes:

background-image: url(nickcage.jpg); // No quotes around the file name

Next, if your html, css and image are all in the same directory then removing the quotes should fix it. If, however, your css or image are in subdirectories of where your html lives, you'll want to make sure you correctly path to the image:

background-image: url(../images/nickcage.jpg); // css and image live in subdorectories

background-image: url(images/nickcage.jpg); // css lives with html but images is a subdirectory

Hope it helps.

Install firebug: http://getfirebug.com/logging . You can use its console to test Javascript code. Google Chrome comes with Web Inspector in which you can do the same. IE and Safari also have Web Developer tools in which you can test Javascript.

Apply the below code where you want to make code to exit application.

System.Windows.Forms.Application.Exit( )

fig, (ax1, ax2, ax3, ax4) = plt.subplots(nrows=1, ncols=4,figsize=(11, 7))

grid = plt.GridSpec(2, 2, wspace=0.2, hspace=0.5)

ax1 = plt.subplot(grid[0, 0])
ax2 = plt.subplot(grid[0, 1:])
ax3 = plt.subplot(grid[1, :1])
ax4 = plt.subplot(grid[1, 1:])

ax1.title.set_text('First Plot')
ax2.title.set_text('Second Plot')
ax3.title.set_text('Third Plot')
ax4.title.set_text('Fourth Plot')

plt.show()

Simply

reset(explode(".", $_SERVER['HTTP_HOST']))

C does not have strings per se -- what you have is a char pointer pointing to some read-only memory containing the characters "blablabla\0". In order to append a character there, you need a) writable memory and b) enough space for the string in its new form. The string literal "blablabla\0" has neither.

The solutions are:

1) Use malloc() et al. to dynamically allocate memory. (Don't forget to free() afterwards.)
2) Use a char array.

When working with strings, consider using strn* variants of the str* functions -- they will help you stay within memory bounds.

Add a style = color:black !important; in your input type.

This command line tool is the business! https://wkhtmltopdf.org/

It uses webkit rendering engine(used in safari and KDE), I tested it on some complex sites and it was by far better than any other tool.

Everything that interacts with the UI must be called in the UI thread (unless it is a frozen object). To do that, you can use the dispatcher.

var disp = /* Get the UI dispatcher, each WPF object has a dispatcher which you can query*/
disp.BeginInvoke(DispatcherPriority.Normal,
        (Action)(() => /*Do your UI Stuff here*/));

I use BeginInvoke here, usually a backgroundworker doesn't need to wait that the UI updates. If you want to wait, you can use Invoke. But you should be careful not to call BeginInvoke to fast to often, this can get really nasty.

By the way, The BackgroundWorker class helps with this kind of taks. It allows Reporting changes, like a percentage and dispatches this automatically from the Background thread into the ui thread. For the most thread <> update ui tasks the BackgroundWorker is a great tool.

Easy to map different set of list by linq without for loop

var List1= new List<Entities1>();

var List2= new List<Entities2>();

var List2 = List1.Select(p => new Entities2
        {
            EntityCode = p.EntityCode,
            EntityId = p.EntityId,
            EntityName = p.EntityName
        }).ToList();

I've just created a little example showing how to implement commands in convention over configuration style. However it requires Reflection.Emit() to be available. The supporting code may seem a little weird but once written it can be used many times.

Teaser:

public class SampleViewModel: BaseViewModelStub
{
    public string Name { get; set; }

    [UiCommand]
    public void HelloWorld()
    {
        MessageBox.Show("Hello World!");
    }

    [UiCommand]
    public void Print()
    {
        MessageBox.Show(String.Concat("Hello, ", Name, "!"), "SampleViewModel");
    }

    public bool CanPrint()
    {
        return !String.IsNullOrEmpty(Name);
    }
}

}

UPDATE: now there seem to exist some libraries like http://www.codeproject.com/Articles/101881/Executing-Command-Logic-in-a-View-Model that solve the problem of ICommand boilerplate code.

First save the file in .py format (for example, my_example.py). And if that file have functions,

def xyz():

        --------

        --------

def abc():

        --------

        --------

In the calling function you just have to type the below lines.

file_name: my_example2.py

============================

import my_example.py


a = my_example.xyz()

b = my_example.abc()

============================

This may happen when the same classname is specified in multiple .aspx.cs files, i.e. when two pages are created with different file name but by mistake have the same classname.

// file a.aspx
public partial class Test1: System.Web.UI.Page

// file b.aspx
public partial class Test1: System.Web.UI.Page

While building the webapplication this gives a warning, but the application runs, however, after publishing the application doesn't work anymore and throws the exception as mentioned in the OP's question.

Making sure that two classnames do no overlap solves the issue.

The Easiest way example to show you how to do that is :

Code :

>>> points = 19.5 >>> total = 22 >>>'Correct answers: {:.2%}'.format(points/total) `

Output : Correct answers: 88.64%

Because none of the answers above worked for me, I write here the solution that finally solved my problem on Ubuntu. My problem was:
I did the following steps:

1. Activate my environment: conda activate MyEnv
2. Start jupyter notebook:jupyter notebook

Although MyEnv was active in the terminal and had an asterix when writing conda env list, but jupyter notebook was started with the base environment. Installing nb_conda and ipykernel didn't solve the problem for me either. Additionally, the conda tab wasn't appearing in jupyter notebook and also clicking on the kernels or going to the menu Kernel->Change Kernel didn't show the kernel MyEnv.
Solution was: install the jupyter_environment_kernel in MyEnv environment:

pip install environment_kernels

After that when starting jupyter notebook, it is started with the right environment. You can also switch between environments without stopping the kernel, by going to the menu Kernel->Change Kernel and selecting the desired kernel.

Why is there no answer for using Reflection API?

private static Object cloneObject(Object obj){
        try{
            Object clone = obj.getClass().newInstance();
            for (Field field : obj.getClass().getDeclaredFields()) {
                field.setAccessible(true);
                field.set(clone, field.get(obj));
            }
            return clone;
        }catch(Exception e){
            return null;
        }
    }

It's really simple.

There is an easy, out of the box implementation: the HTML 5 input type="date" and the other date-related input types.

Okay, you can't style the controls that much and it doesn't work on every browser, but still it can be a very good option in the long term if all modern browsers support it and don't want to include heavy libraries that don't always work that good on mobile devices.

Re the solution for SqlBulkCopy:

I used the StreamReader to convert and process the text file. The result was a list of my object.

I created a class than takes Datatable or a List<T> and a Buffer size (CommitBatchSize). It will convert the list to a data table using an extension (in the second class).

It works very fast. On my PC, I am able to insert more than 10 million complicated records in less than 10 seconds.

Here is the class:

using System;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DAL
{

public class BulkUploadToSql<T>
{
    public IList<T> InternalStore { get; set; }
    public string TableName { get; set; }
    public int CommitBatchSize { get; set; }=1000;
    public string ConnectionString { get; set; }

    public void Commit()
    {
        if (InternalStore.Count>0)
        {
            DataTable dt;
            int numberOfPages = (InternalStore.Count / CommitBatchSize)  + (InternalStore.Count % CommitBatchSize == 0 ? 0 : 1);
            for (int pageIndex = 0; pageIndex < numberOfPages; pageIndex++)
                {
                    dt= InternalStore.Skip(pageIndex * CommitBatchSize).Take(CommitBatchSize).ToDataTable();
                BulkInsert(dt);
                }
        } 
    }

    public void BulkInsert(DataTable dt)
    {
        using (SqlConnection connection = new SqlConnection(ConnectionString))
        {
            // make sure to enable triggers
            // more on triggers in next post
            SqlBulkCopy bulkCopy =
                new SqlBulkCopy
                (
                connection,
                SqlBulkCopyOptions.TableLock |
                SqlBulkCopyOptions.FireTriggers |
                SqlBulkCopyOptions.UseInternalTransaction,
                null
                );

            // set the destination table name
            bulkCopy.DestinationTableName = TableName;
            connection.Open();

            // write the data in the "dataTable"
            bulkCopy.WriteToServer(dt);
            connection.Close();
        }
        // reset
        //this.dataTable.Clear();
    }

}

public static class BulkUploadToSqlHelper
{
    public static DataTable ToDataTable<T>(this IEnumerable<T> data)
    {
        PropertyDescriptorCollection properties =
            TypeDescriptor.GetProperties(typeof(T));
        DataTable table = new DataTable();
        foreach (PropertyDescriptor prop in properties)
            table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);
        foreach (T item in data)
        {
            DataRow row = table.NewRow();
            foreach (PropertyDescriptor prop in properties)
                row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
            table.Rows.Add(row);
        }
        return table;
    }
}

}

Here is an example when I want to insert a List of my custom object List<PuckDetection> (ListDetections):

var objBulk = new BulkUploadToSql<PuckDetection>()
{
        InternalStore = ListDetections,
        TableName= "PuckDetections",
        CommitBatchSize=1000,
        ConnectionString="ENTER YOU CONNECTION STRING"
};
objBulk.Commit();

The BulkInsert class can be modified to add column mapping if required. Example you have an Identity key as first column.(this assuming that the column names in the datatable are the same as the database)

//ADD COLUMN MAPPING
foreach (DataColumn col in dt.Columns)
{
        bulkCopy.ColumnMappings.Add(col.ColumnName, col.ColumnName);
}

Your approach is OK

Maybe slightly clearer (to me anyway!)

UPDATE
  T1
SET
  [Description] = t2.[Description]
FROM
   Table1 T1
   JOIN
   [Table2] t2 ON t2.[ID] = t1.DescriptionID

Both this and your query should run the same performance wise because it is the same query, just laid out differently.

?vector

X <- vector(mode="character", length=10)

This will give you empty strings which get printed as two adjacent double quotes, but be aware that there are no double-quote characters in the values themselves. That's just a side-effect of how print.default displays the values. They can be indexed by location. The number of characters will not be restricted, so if you were expecting to get 10 character element you will be disappointed.

>  X[5] <- "character element in 5th position"

>  X
 [1] ""                                  ""                                 
 [3] ""                                  ""                                 
 [5] "character element in 5th position" ""                                 
 [7] ""                                  ""                                 
 [9] ""                                  "" 
>  nchar(X)
 [1]  0  0  0  0 33  0  0  0  0  0

> length(X)
[1] 10

Simply add the eventhandler to the button when creating it.

 button.Click += new EventHandler(this.button_Click);

void button_Click(object sender, System.EventArgs e)
{
//your stuff...
}

To update one column here are some syntax options:

Option 1

var ls=new int[]{2,3,4};
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>a.status=true);
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
     db.SomeTable
       .Where(x=>ls.Contains(x.friendid))
       .ToList()
       .ForEach(a=>a.status=true);

     db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
    }
    db.SubmitChanges();
}

Update

As requested in the comment it might make sense to show how to update multiple columns. So let's say for the purpose of this exercise that we want not just to update the status at ones. We want to update name and status where the friendid is matching. Here are some syntax options for that:

Option 1

var ls=new int[]{2,3,4};
var name="Foo";
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
    db.SomeTable
        .Where(x=>ls.Contains(x.friendid))
        .ToList()
        .ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
        some.name=name;
    }
    db.SubmitChanges();
}

Update 2

In the answer I was using LINQ to SQL and in that case to commit to the database the usage is:

db.SubmitChanges();

But for Entity Framework to commit the changes it is:

db.SaveChanges()

Found a Fix:

1. First ensure that printing is working from Report Manager (open a report in Report Manager and print from there).

2. If it works go to Step 3, if you received the same error you need to install the following patches on the Report Server.

This solution might be easier. But it does require a higher API version(23). simply add this code to your toolbar in XML:

<Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?android:attr/actionBarSize"
    android:background="?android:attr/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    android:titleTextColor="#ffffffff" />

Here is a thing I made for myself to clear out how things work. I guess others too can find this concrete example useful:

doit().then(function() { log('Now finally done!') });_x000D_
log('---- But notice where this ends up!');_x000D_
_x000D_
// For pedagogical reasons I originally wrote the following doit()-function so that _x000D_
// it was clear that it is a promise. That way wasn't really a normal way to do _x000D_
// it though, and therefore Slikts edited my answer. I therefore now want to remind _x000D_
// you here that the return value of the following function is a promise, because _x000D_
// it is an async function (every async function returns a promise). _x000D_
async function doit() {_x000D_
  log('Calling someTimeConsumingThing');_x000D_
  await someTimeConsumingThing();_x000D_
  log('Ready with someTimeConsumingThing');_x000D_
}_x000D_
_x000D_
function someTimeConsumingThing() {_x000D_
  return new Promise(function(resolve,reject) {_x000D_
    setTimeout(resolve, 2000);_x000D_
  })_x000D_
}_x000D_
_x000D_
function log(txt) {_x000D_
  document.getElementById('msg').innerHTML += txt + '<br>'_x000D_
}

<div id='msg'></div>

it can be installed separated, and it's not included in framwork, choose tab list "extensions" and it exists there are and more other libs, all is ok not needed to used old libs etc, exists old 20 30 and 4001

With C# 8:

int[] array = { 1, 3, 5 };
var lastItem = array[^1]; // 5

I add credentials for HttpWebRequest.

myReq.UseDefaultCredentials = true;
myReq.PreAuthenticate = true;
myReq.Credentials = CredentialCache.DefaultCredentials;

Why do I need the descriptor class?

It gives you extra control over how attributes work. If you're used to getters and setters in Java, for example, then it's Python's way of doing that. One advantage is that it looks to users just like an attribute (there's no change in syntax). So you can start with an ordinary attribute and then, when you need to do something fancy, switch to a descriptor.

An attribute is just a mutable value. A descriptor lets you execute arbitrary code when reading or setting (or deleting) a value. So you could imagine using it to map an attribute to a field in a database, for example – a kind of ORM.

Another use might be refusing to accept a new value by throwing an exception in __set__ – effectively making the "attribute" read only.

What is instance and owner here? (in __get__). What is the purpose of these parameters?

This is pretty subtle (and the reason I am writing a new answer here - I found this question while wondering the same thing and didn't find the existing answer that great).

A descriptor is defined on a class, but is typically called from an instance. When it's called from an instance both instance and owner are set (and you can work out owner from instance so it seems kinda pointless). But when called from a class, only owner is set – which is why it's there.

This is only needed for __get__ because it's the only one that can be called on a class. If you set the class value you set the descriptor itself. Similarly for deletion. Which is why the owner isn't needed there.

How would I call/use this example?

Well, here's a cool trick using similar classes:

class Celsius:

    def __get__(self, instance, owner):
        return 5 * (instance.fahrenheit - 32) / 9

    def __set__(self, instance, value):
        instance.fahrenheit = 32 + 9 * value / 5


class Temperature:

    celsius = Celsius()

    def __init__(self, initial_f):
        self.fahrenheit = initial_f


t = Temperature(212)
print(t.celsius)
t.celsius = 0
print(t.fahrenheit)

(I'm using Python 3; for python 2 you need to make sure those divisions are / 5.0 and / 9.0). That gives:

100.0
32.0

Now there are other, arguably better ways to achieve the same effect in python (e.g. if celsius were a property, which is the same basic mechanism but places all the source inside the Temperature class), but that shows what can be done...

Complete answer (.Net Core 3.1)

Most answers here are correct but taken a bit out of context, so I will provide a full-fledged answer which works for Asp.Net Core 3.1. For completeness' sake:

[Route("health")]
[ApiController]
public class HealthController : Controller
{
    [HttpGet("some_health_url")]
    public ActionResult SomeHealthMethod() {}
}

[Route("v2")]
[ApiController]
public class V2Controller : Controller
{
    [HttpGet("some_url")]
    public ActionResult SomeV2Method()
    {
        return RedirectToAction("SomeHealthMethod", "Health"); // omit "Controller"
    }
}

If you try to use any of the url-specific strings, e.g. "some_health_url", it will not work!

Short answer: You can't.

Technically there is an accurate way, which would be checking the property:

history.previous

However, it won't work. The problem with this is that in most browsers this is considered a security violation and usually just returns undefined.

history.length

Is a property that others have suggested...
However, the length doesn't work completely because it doesn't indicate where in the history you are. Additionally, it doesn't always start at the same number. A browser not set to have a landing page, for example, starts at 0 while another browser that uses a landing page will start at 1.

Most of the time a link is added that calls:

history.back();

or

 history.go(-1);

and it's just expected that if you can't go back then clicking the link does nothing.

Karan Bhandari's answer is good, but the AccountController added in a project is very likely a Mvc.Controller. To convert his answer for use in an ApiController change HttpContext.Current.GetOwinContext() to Request.GetOwinContext() and make sure you have added the following 2 using statements:

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;

The reason your code doesn't work is because the count function is asynchronous, it doesn't synchronously return a value.

Here's an example of usage:

userModel.count({}, function( err, count){
    console.log( "Number of users:", count );
})

This is a new feature of C# 6 called an expression bodied member that allows you to define a getter only property using a lambda like function.

While it is considered syntactic sugar for the following, they may not produce identical IL:

public int MaxHealth
{
    get
    {
        return Memory[Address].IsValid
               ?   Memory[Address].Read<int>(Offs.Life.MaxHp)
               :   0;
    }
}

It turns out that if you compile both versions of the above and compare the IL generated for each you'll see that they are NEARLY the same.

Here is the IL for the classic version in this answer when defined in a class named TestClass:

.property instance int32 MaxHealth()
{
    .get instance int32 TestClass::get_MaxHealth()
}

.method public hidebysig specialname 
    instance int32 get_MaxHealth () cil managed 
{
    // Method begins at RVA 0x2458
    // Code size 71 (0x47)
    .maxstack 2
    .locals init (
        [0] int32
    )

}

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

If you have a budget for your IDE, you should give Wingware Professional a try, see wingware.com .

You can use Object.assign() with an empty array literal [] as the target:

const input = {_x000D_
  "0": "1",_x000D_
  "1": "2",_x000D_
  "2": "3",_x000D_
  "3": "4"_x000D_
}_x000D_
_x000D_
const output = Object.assign([], input)_x000D_
_x000D_
console.log(output)

If you check the polyfill, Object.assign(target, ...sources) just copies all the enumerable own properties from the source objects to a target object. If the target is an array, it will add the numerical keys to the array literal and return that target array object.

FOR FADE add this first line with your animation's object.

.animate().alpha(1).setDuration(2000);

FOR EXAMPLE

i had the same issue. go to Sql Server Configuration management->SQL Server network config->protocols for 'servername' and check named pipes is enabled.

np.append needs the array as the first argument and the list you want to append as the second:

mean_data = np.append(mean_data, [ur, ua, np.mean(data[samepoints,-1])])

Sys.sleep() will not work if the CPU usage is very high; as in other critical high priority processes are running (in parallel).

This code worked for me. Here I am printing 1 to 1000 at a 2.5 second interval.

for (i in 1:1000)
{
  print(i)
  date_time<-Sys.time()
  while((as.numeric(Sys.time()) - as.numeric(date_time))<2.5){} #dummy while loop
}

What about npm i -g npm? Did you try to run this as well?

Well, here the positioning of the css and script links makes a to of difference. Bootstrap executes in CSS and then Scripts fashion. So if you have even one script written at incorrect place it makes a lot of difference. You can follow the below snippet and change your code accordingly.

Variant 1

In order to avoid visual klikering you might need to use:

bindingSource.RaiseListChangeEvent = false 

or

myTabControl.RaiseSelectedIndexChanged = false

Remove a tab page:

myTabControl.Remove(myTabPage);

Add a tab page:

myTabControl.Add(myTabPage);

Insert a tab page at specific location:

myTabControl.Insert(2, myTabPage);

Do not forget to revers the changes:

bindingSource.RaiseListChangeEvent = true;

or

myTabControl.RaiseSelectedIndexChanged = true;

Variant 2

myTabPage.parent = null;
myTabPage.parent = myTabControl;

SqlConnection con = new SqlConnection();
con.ConnectionString="Data Source=DOTNET-PC\\SQLEXPRESS;Initial Catalog=apptivator;Integrated Security=True";

Avoid any? for large arrays.

• any? is O(n)
• empty? is O(1)

any? does not check the length but actually scans the whole array for truthy elements.

static VALUE
rb_ary_any_p(VALUE ary)
{
  long i, len = RARRAY_LEN(ary);
  const VALUE *ptr = RARRAY_CONST_PTR(ary);

  if (!len) return Qfalse;
  if (!rb_block_given_p()) {
    for (i = 0; i < len; ++i) if (RTEST(ptr[i])) return Qtrue;
  }
  else {
    for (i = 0; i < RARRAY_LEN(ary); ++i) {
        if (RTEST(rb_yield(RARRAY_AREF(ary, i)))) return Qtrue;
    }
  }
  return Qfalse;
}

empty? on the other hand checks the length of the array only.

static VALUE
rb_ary_empty_p(VALUE ary)
{
  if (RARRAY_LEN(ary) == 0)
    return Qtrue;
  return Qfalse;
}

The difference is relevant if you have "sparse" arrays that start with lots of nil values, like for example an array that was just created.

add 0.5 before casting (if x > 0) or subtract 0.5 (if x < 0), because the compiler will always truncate.

float x = 55; // stored as 54.999999...
x = x + 0.5 - (x<0); // x is now 55.499999...
int y = (int)x; // truncated to 55

C++11 also introduces std::round, which likely uses a similar logic of adding 0.5 to |x| under the hood (see the link if interested) but is obviously more robust.

A follow up question might be why the float isn't stored as exactly 55. For an explanation, see this stackoverflow answer.

In order to keep both versions, I just changed the value of PATH environment variable by putting the new version's git path "/usr/local/git/bin/" at the beginning, it forces to use the newest version:

$ echo $PATH

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin/

$ git --version

git version 2.4.9 (Apple Git-60)

original value: /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin/

new value: /usr/local/git/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin

$ export PATH=/usr/local/git/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin

$ git --version

git version 2.13.0

SQLServer runs the default instance over port 1433. If you specify the port as port 1433, SQLServer will only look for the default instance. The name of the default instance was created at setup and usually is SQLEXPRESSxxx_xx_ENU.

The instance name also matches the folder name created in Program Files -> Microsoft SQL Server. So if you look there and see one folder named SQLEXPRESSxxx_xx_ENU it is the default instance.

Folders named MSSQL12.myInstanceName (for SQLServer 2012) are named instances in SQL Server and are not accessed via port 1433.

So if your program is accessing a default instance in the database, specify port 1433, and you may not need to specify the instance name.

If your program is accessing a named instance (not the default instance) in the database DO NOT specify the port but you must specify the instance name.

I hope this clarifies some of the confusion emanating from the errors above.

Similar to Ryan Rodemoyer's answer, I found that when the UriTemplate on the Contract is not valid you can get this error. In my case, I was using the same parameter twice. For example:

/Root/{Name}/{Name}

by this you can load html file which is in your project Assets(bundle) to webView.

 UIWebView *web = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
    [web loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] 
                                pathForResource:@"test" ofType:@"html"]isDirectory:NO]]];

may be this is useful to you.

Timer

As mentioned on the javadocs you are better off using a ScheduledThreadPoolExecutor.

ScheduledThreadPoolExecutor

Use this class when your use case requires multiple worker threads and the sleep interval is small. How small ? Well, I'd say about 15 minutes. The AlarmManager starts schedule intervals at this time and it seems to suggest that for smaller sleep intervals this class can be used. I do not have data to back the last statement. It is a hunch.

Service

Your service can be closed any time by the VM. Do not use services for recurring tasks. A recurring task can start a service, which is another matter entirely.

BroadcastReciever with AlarmManager

For longer sleep intervals (>15 minutes), this is the way to go. AlarmManager already has constants ( AlarmManager.INTERVAL_DAY ) suggesting that it can trigger tasks several days after it has initially been scheduled. It can also wake up the CPU to run your code.

You should use one of those solutions based on your timing and worker thread needs.

Spring provides a very clean division between controllers, JavaBean models, and views.

If you use Spring Boot, you can also enable a “debug” mode by starting your application with a --debug flag.

java -jar myapp.jar --debug

You can also specify debug=true in your application.properties.

When the debug mode is enabled, a selection of core loggers (embedded container, Hibernate, and Spring Boot) are configured to output more information. Enabling the debug mode does not configure your application to log all messages with DEBUG level.

Alternatively, you can enable a “trace” mode by starting your application with a --trace flag (or trace=true in your application.properties). Doing so enables trace logging for a selection of core loggers (embedded container, Hibernate schema generation, and the whole Spring portfolio).

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html

I came across this question, and figured out sorting the iterators directly would be a way to sort the values and keep track of indices; There is no need to define an extra container of pairs of ( value, index ) which is helpful when the values are large objects; The iterators provides the access to both the value and the index:

/*
 * a function object that allows to compare
 * the iterators by the value they point to
 */
template < class RAIter, class Compare >
class IterSortComp
{
    public:
        IterSortComp ( Compare comp ): m_comp ( comp ) { }
        inline bool operator( ) ( const RAIter & i, const RAIter & j ) const
        {
            return m_comp ( * i, * j );
        }
    private:
        const Compare m_comp;
};

template <class INIter, class RAIter, class Compare>
void itersort ( INIter first, INIter last, std::vector < RAIter > & idx, Compare comp )
{ 
    idx.resize ( std::distance ( first, last ) );
    for ( typename std::vector < RAIter >::iterator j = idx.begin( ); first != last; ++ j, ++ first )
        * j = first;

    std::sort ( idx.begin( ), idx.end( ), IterSortComp< RAIter, Compare > ( comp ) );
}

as for the usage example:

std::vector < int > A ( n );

// populate A with some random values
std::generate ( A.begin( ), A.end( ), rand );

std::vector < std::vector < int >::const_iterator > idx;
itersort ( A.begin( ), A.end( ), idx, std::less < int > ( ) );

now, for example, the 5th smallest element in the sorted vector would have value **idx[ 5 ] and its index in the original vector would be distance( A.begin( ), *idx[ 5 ] ) or simply *idx[ 5 ] - A.begin( ).

Setting async to false means the instructions following the ajax request will have to wait for the request to complete. Below is one case where one have to set async to false, for the code to work properly.

var phpData = (function get_php_data() {
  var php_data;
  $.ajax({
    url: "http://somesite/v1/api/get_php_data",
    async: false, 
    //very important: else php_data will be returned even before we get Json from the url
    dataType: 'json',
    success: function (json) {
      php_data = json;
    }
  });
  return php_data;
})();

Above example clearly explains the usage of async:false

By setting it to false, we have made sure that once the data is retreived from the url ,only after that return php_data; is called

I can't understand why this issue gets pounded into the ground when in 30 seconds you can code a two-column table and solve the problem.

This div column height problem comes up all over a typical layout. Why resort to scripting when a plain old basic HTML tag will do it? Unless there are huge and numerous tables on a layout, I don't buy the argument that tables are significantly slower.

window.addEventListener("beforeunload", function (e) {
    // do something
}, false);

It depends on the shell (and its configuration) in standard bash only the command is stored without the date and time (check .bash_history if there is any timestamp there).

To have bash store the timestamp you need to set HISTTIMEFORMAT before executing the commands, e.g. in .bashrc or .bash_profile. This will cause bash to store the timestamps in .bash_history (see the entries starting with #).

The answer depends on what is in your hash. If you have a simple hash a simple

print map { "$_ $h{$_}\n" } keys %h;

or

print "$_ $h{$_}\n" for keys %h;

will do, but if you have a hash that is populated with references you will something that can walk those references and produce a sensible output. This walking of the references is normally called serialization. There are many modules that implement different styles, some of the more popular ones are:

• Data::Dumper
• Data::Dump::Streamer
• YAML::XS
• JSON::XS
• XML::Dumper

Due to the fact that Data::Dumper is part of the core Perl library, it is probably the most popular; however, some of the other modules have very good things to offer.

In case you haven't found the solution on the other answers, that's how I solved the issue.

Application.Current.Dispatcher.BeginInvoke(new Action(() =>
{
    TEXTBOX_OBJECT.Focus();
}), System.Windows.Threading.DispatcherPriority.Render);

From what I understand the other solutions may not work because the call to Focus() is invoked before the application has rendered the other components.

Edit:

Disclaimer: you should usually prefer installing a mature tool like xmllint to do a job like this. XML/HTML can be a horribly mutilated mess. However, there are valid situations where using existing tooling is preferable over manually installing new ones, and where it is also a safe bet the XML's source is valid (enough). I've written this script for one of those cases, but they are rare, so precede with caution.

I'd like to add a pure Bash solution, as it is not 'that' difficult to just do it by hand, and sometimes you won't want to install an extra tool to do the job.

#!/bin/bash

declare -i currentIndent=0
declare -i nextIncrement=0
while read -r line ; do
  currentIndent+=$nextIncrement
  nextIncrement=0
  if [[ "$line" == "</"* ]]; then # line contains a closer, just decrease the indent
    currentIndent+=-1
  else
    dirtyStartTag="${line%%>*}"
    dirtyTagName="${dirtyStartTag%% *}"
    tagName="${dirtyTagName//</}"
    # increase indent unless line contains closing tag or closes itself
    if [[ ! "$line" =~ "</$tagName>" && ! "$line" == *"/>"  ]]; then
      nextIncrement+=1
    fi
  fi

  # print with indent
  printf "%*s%s" $(( $currentIndent * 2 )) # print spaces for the indent count
  echo $line
done <<< "$(cat - | sed 's/></>\n</g')" # separate >< with a newline

Paste it in a script file, and pipe in the xml. This assumes the xml is all on one line, and there are no extra spaces anywhere. One could easily add some extra \s* to the regexes to fix that.

In Python 2, raw_input() returns a string, and input() tries to run the input as a Python expression.

Since getting a string was almost always what you wanted, Python 3 does that with input(). As Sven says, if you ever want the old behaviour, eval(input()) works.

Pandas 0.24.0+ solution

In Pandas 0.24.0 a new feature was introduced specifically designed for fast writes to Postgres. You can learn more about it here: https://pandas.pydata.org/pandas-docs/stable/user_guide/io.html#io-sql-method

import csv
from io import StringIO

from sqlalchemy import create_engine

def psql_insert_copy(table, conn, keys, data_iter):
    # gets a DBAPI connection that can provide a cursor
    dbapi_conn = conn.connection
    with dbapi_conn.cursor() as cur:
        s_buf = StringIO()
        writer = csv.writer(s_buf)
        writer.writerows(data_iter)
        s_buf.seek(0)

        columns = ', '.join('"{}"'.format(k) for k in keys)
        if table.schema:
            table_name = '{}.{}'.format(table.schema, table.name)
        else:
            table_name = table.name

        sql = 'COPY {} ({}) FROM STDIN WITH CSV'.format(
            table_name, columns)
        cur.copy_expert(sql=sql, file=s_buf)

engine = create_engine('postgresql://myusername:mypassword@myhost:5432/mydatabase')
df.to_sql('table_name', engine, method=psql_insert_copy)

It is used in the new short hand for/loop

final List<String> list = new ArrayList<String>();
for (final String s : list)
{
   System.out.println(s);
}

and the ternary operator

list.isEmpty() ? true : false;

This will get you the timezone as a PHP variable. I wrote a function using jQuery and PHP. This is tested, and does work!

On the PHP page where you are want to have the timezone as a variable, have this snippet of code somewhere near the top of the page:

<?php    
    session_start();
    $timezone = $_SESSION['time'];
?>

This will read the session variable "time", which we are now about to create.

On the same page, in the <head> section, first of all you need to include jQuery:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>

Also in the <head> section, paste this jQuery:

<script type="text/javascript">
    $(document).ready(function() {
        if("<?php echo $timezone; ?>".length==0){
            var visitortime = new Date();
            var visitortimezone = "GMT " + -visitortime.getTimezoneOffset()/60;
            $.ajax({
                type: "GET",
                url: "http://example.com/timezone.php",
                data: 'time='+ visitortimezone,
                success: function(){
                    location.reload();
                }
            });
        }
    });
</script>

You may or may not have noticed, but you need to change the url to your actual domain.

One last thing. You are probably wondering what the heck timezone.php is. Well, it is simply this: (create a new file called timezone.php and point to it with the above url)

<?php
    session_start();
    $_SESSION['time'] = $_GET['time'];
?>

If this works correctly, it will first load the page, execute the JavaScript, and reload the page. You will then be able to read the $timezone variable and use it to your pleasure! It returns the current UTC/GMT time zone offset (GMT -7) or whatever timezone you are in.

You can read more about this on my blog

Just type below command on your command prompt & it will bind all sql file into single sql file,

c:/xampp/mysql/bin/sql/ type *.sql > OneFile.sql;

XML Element is a XML Node but with additional elements like attributes.

<a>Lorem Ipsum</a>  //This is a node

<a id="sample">Lorem Ipsum</a>  //This is an element

Everyone explained the topic very well. There is one more point i would like add about .load() method.

As per Load document if you add suffixed selector in data url then it will not execute scripts in loading content.

Working Plunker

            $(document).ready(function(){
                $("#secondPage").load("mySecondHtmlPage.html #content");
            })

On the other hand, after removing selector in url, scripts in new content will run. Try this example

after removing #content in url in index.html file

            $(document).ready(function(){
                $("#secondPage").load("mySecondHtmlPage.html");
            })

There is no such in-built feature provided by other methods in discussion.

Thank you. I use passing in an object as a parameter. My Android code is below

    String oPerson= null;
    if (CheckAddress("5556", oPerson))
    {
        Toast.makeText(this, 
                "It's Match! " + oPerson,                   
                Toast.LENGTH_LONG).show();
    }

    private boolean CheckAddress(String iAddress, String oPerson)
{
    Cursor cAddress = mDbHelper.getAllContacts();
    String address = "";        
    if (cAddress.getCount() > 0) {
        cAddress.moveToFirst();
        while (cAddress.isAfterLast() == false) {
            address = cAddress.getString(2).toString();
            oPerson = cAddress.getString(1).toString(); 
            if(iAddress.indexOf(address) != -1)
            {
                Toast.makeText(this, 
                        "Person : " + oPerson,                  
                        Toast.LENGTH_LONG).show();
                System.out.println(oPerson);
                cAddress.close();
                return true;                    
            }
            else cAddress.moveToNext();
        }
    }
    cAddress.close();
    return false;
}

The result is

Person : John

It's Match! null

Actually, "It's Match! John"

Please check my mistake.

You can also create a soft link to your script in one of the directories (/usr/local/bin for example) in the super user PATH. It'll then be available to the sudo.

chmod +x foo.sh
sudo ln -s path-to-foo.sh /usr/local/bin/foo

Have a look at this answer to have an idea of which directory to put soft link in.

Resizing images in a canvas element is generally bad idea since it uses the cheapest box interpolation. The resulting image noticeable degrades in quality. I'd recommend using http://nodeca.github.io/pica/demo/ which can perform Lanczos transformation instead. The demo page above shows difference between canvas and Lanczos approaches.

It also uses web workers for resizing images in parallel. There is also WEBGL implementation.

There are some online image resizers that use pica for doing the job, like https://myimageresizer.com

My issue was the failure to import numpy into my python files. I was receiving the "ModuleNotFoundError: No module named 'numpy'". I ran into the same issue and I was not referencing python3 on the installation of numpy. I inputted the following into my terminal for OSX and my problems were solved:

python3 -m pip install numpy

If you want to run the scripts in parallel and give them different arguments you can do like below.

import os

For POI 3.17 this worked for me

switch (cellh.getCellTypeEnum()) {
    case FORMULA: 
        if (cellh.getCellFormula().indexOf("LINEST") >= 0) {
            value = Double.toString(cellh.getNumericCellValue());
        } else {
            value = XLS_getDataFromCellValue(evaluator.evaluate(cellh));
        }
        break;
    case NUMERIC:
        value = Double.toString(cellh.getNumericCellValue());
        break;
    case STRING:
        value = cellh.getStringCellValue();
        break;
    case BOOLEAN:
        if(cellh.getBooleanCellValue()){
            value = "true";
        } else {
            value = "false";
        }
        break;
    default:
        value = "";
        break;
}

You can either use JavaScript or CSS3.

JavaScript solution: Use an absolute positioned <img> tag and resize it on the page load and whenever the page resizes. Be careful of possible bugs when trying to get the page/window size.

CSS3 solution: Use the CSS3 background-size property. You might use either 100% 100% or contain or cover, depending on how you want the image to resize. Of course, this only works on modern browsers.

Originally there was just 302

The idea is that:

• if you were doing a GET at some location, you would redo your GET to the new URL
• if you were doing a POST at some location, you would redo your POST to the new URL
• if you were doing a PUT at some location, you would redo your PUT to the new URL
• if you were doing a DELETE at some location, you would redo your DELETE to the new URL
• etc

Unfortunately every browser did it wrong. When getting a 302, they would always switch to GET at the new URL, rather than retrying the request with the same verb (e.g., POST):

• Mosaic did it wrong
• Netscape copied the bugs in Mosaic; so they got it wrong
• Internet Explorer copied the bugs in Netscape; so they got it wrong

It became de-facto wrong.

All browsers got 302 wrong. So 303 and 307 were created.

Alternatively:

To check wheather or not a given Binary Tree is Binary Search Tree here's is an Alternative Approach .

Traverse Tree In Inorder Fashion (i.e. Left Child --> Parent --> Right Child ) , Store Traversed Node Data in a temporary Variable lets say temp , just before storing into temp , Check wheather current Node's data is higher then previous one or not . Then just break it out , Tree is not Binary Search Tree else traverse untill end.

Below is an example with Java:

public static boolean isBinarySearchTree(Tree root)
{
    if(root==null)
        return false;

    isBinarySearchTree(root.left);
    if(tree.data<temp)
        return false;
    else
        temp=tree.data;
    isBinarySearchTree(root.right);
    return true;
}

Maintain temp variable outside

Quotes!

if [ "$1" != -v ]; then

Otherwise, when $1 is completely empty, your test becomes:

[ != -v ]

instead of

[ "" != -v ]

...and != is not a unary operator (that is, one capable of taking only a single argument).

You can get around this even more easily with the Rebase extension, just use hg pull --rebase and your commits are automatically re-comitted to the pulled revision, avoiding the branching issue.

If you are getting this instead:

Error: Template parse errors:

There is no directive with "exportAs" set to "ngModel"

Which was reported as a bug in github, then likely it is not a bug since you might:

1. have a syntax error (e.g. an extra bracket: [(ngModel)]]=), OR
2. be mixing Reactive forms directives, such as formControlName, with the ngModel directive. This "has been deprecated in Angular v6 and will be removed in Angular v7", since this mixes both form strategies, making it:

• seem like the actual ngModel directive is being used, but in fact it's an input/output property named ngModel on the reactive form directive that simply approximates (some of) its behavior. Specifically, it allows getting/setting the value and intercepting value events. However, some of ngModel's other features - like delaying updates withngModelOptions or exporting the directive - simply don't work (...)

• this pattern mixes template-driven and reactive forms strategies, which we generally don't recommend because it doesn't take advantage of the full benefits of either strategy. (...)

• To update your code before v7, you'll want to decide whether to stick with reactive form directives (and get/set values using reactive forms patterns) or switch over to template-driven directives.

When you have an input like this:

<input formControlName="first" [(ngModel)]="value">

It will show a warning about mixed form strategies in the browser's console:

It looks like you're using ngModel on the same form field as formControlName.

However, if you add the ngModel as a value in a reference variable, example:

<input formControlName="first" #firstIn="ngModel" [(ngModel)]="value">

The error above is then triggered and no warning about strategy mixing is shown.

Put it inside a table and then do on her:

var tabPom = document.getElementById("tabPomId");
$(tabPom ).prop('disabled', true/false);

The relevant documentation on Apple's site, Specifying a Webpage Icon for Web Clip.

There is no need to put anything in the head of your document. If no icons are specified using a link element, the website root directory is searched for icons with the apple-touch-icon or apple-touch-icon-precomposed prefix.

For example, if the appropriate icon size for the device is 57 x 57, the system searches for filenames in the following order:

• apple-touch-icon-57x57-precomposed.png
• apple-touch-icon-57x57.png
• apple-touch-icon-precomposed.png
• apple-touch-icon.png

List and Sort Processes by Memory Usage:

ps -e -orss=,args= | sort -b -k1,1n | pr -TW$COLUMNS

You could use $.ajax to avoid the natural behaviour of <form method="POST">. You could, for example, add an event to the submission button and treat the POST request as AJAX.

Escape your HTML tags ...

<resources>
    <string name="somestring">
        &lt;B&gt;Title&lt;/B&gt;&lt;BR/&gt;

    </string>
</resources>

In answer to your second question: Yes a HashMap can hold different types of objects. Whether that's a good idea or not depends on the problem you're trying to solve.

That said, your example won't work. The int value is not an Object. You have to use the Integer wrapper class to store an int value in a HashMap

For people landing here from google like me and just want to build containers using multiple docker-compose files with one shared service:

Sometimes you have different projects that would share e.g. a database docker container. Only the first run should start the DB-Docker, the second should be detect that the DB is already running and skip this. To achieve such a behaviour we need the Dockers to lay in the same network and in the same project. Also the docker container name needs to be the same.

1st: Set the same network and container name in docker-compose

docker-compose in project 1:

version: '3'

services:
    service1:
        depends_on:
            - postgres
        # ...
        networks:
            - dockernet

    postgres:
        container_name: project_postgres
        image: postgres:10-alpine
        restart: always
        # ...
        networks:
            - dockernet

networks:
    dockernet:

docker-compose in project 2:

version: '3'

services:
    service2:
        depends_on:
            - postgres
        # ...
        networks:
            - dockernet

    postgres:
        container_name: project_postgres
        image: postgres:10-alpine
        restart: always
        # ...
        networks:
            - dockernet

networks:
    dockernet:

2nd: Set the same project using -p param or put both files in the same directory.

docker-compose -p {projectname} up

ClassLoader.getResourceAsStream().

As stated in the comment below, if you are in a multi-ClassLoader environment (such as unit testing, webapps, etc.) you may need to use Thread.currentThread().getContextClassLoader(). See http://stackoverflow.com/questions/2308188/getresourceasstream-vs-fileinputstream/2308388#comment21307593_2308388.

Alan is correct when he says there's designer support. Rhywun is incorrect when he implies you cannot choose the foreign key table. What he means is that in the UI the foreign key table drop down is greyed out - all that means is he has not right clicked on the correct table to add the foreign key to.

In summary, right click on the foriegn key table and then via the 'Table Properties' > 'Add Relations' option you select the related primary key table.

I've done it numerous times and it works.

Another option is

if (myString?.trim()) {
  ...
}

You could easily implement an observer (the "watch" method) on the "hash" property of "window.location" object.

Firefox has its own implementation for watching changes of object, but if you use some other implementation (such as Watch for object properties changes in JavaScript) - for other browsers, that will do the trick.

The code will look like this:

window.location.watch(
    'hash',
    function(id,oldVal,newVal){
        console.log("the window's hash value has changed from "+oldval+" to "+newVal);
    }
);

Then you can test it:

var myHashLink = "home";
window.location = window.location + "#" + myHashLink;

And of course that will trigger your observer function.

You have to be clear on what you mean by "JSON".

Some people use the term JSON incorrectly to refer to a plain old JavaScript object, such as [{a: 1}]. This one happens to be an array. If you want to add a new element to the array, just push it, as in

var arr = [{a: 1}];
arr.push({b: 2});

< [{a: 1}, {b: 2}]

The word JSON may also be used to refer to a string which is encoded in JSON format:

var json = '[{"a": 1}]';

Note the (single) quotation marks indicating that this is a string. If you have such a string that you obtained from somewhere, you need to first parse it into a JavaScript object, using JSON.parse:

var obj = JSON.parse(json);

Now you can manipulate the object any way you want, including push as shown above. If you then want to put it back into a JSON string, then you use JSON.stringify:

var new_json = JSON.stringify(obj.push({b: 2}));
'[{"a": 1}, {"b": 1}]'

JSON is also used as a common way to format data for transmission of data to and from a server, where it can be saved (persisted). This is where ajax comes in. Ajax is used both to obtain data, often in JSON format, from a server, and/or to send data in JSON format up to to the server. If you received a response from an ajax request which is JSON format, you may need to JSON.parse it as described above. Then you can manipulate the object, put it back into JSON format with JSON.stringify, and use another ajax call to send the data to the server for storage or other manipulation.

You use the term "JSON file". Normally, the word "file" is used to refer to a physical file on some device (not a string you are dealing with in your code, or a JavaScript object). The browser has no access to physical files on your machine. It cannot read or write them. Actually, the browser does not even really have the notion of a "file". Thus, you cannot just read or write some JSON file on your local machine. If you are sending JSON to and from a server, then of course, the server might be storing the JSON as a file, but more likely the server would be constructing the JSON based on some ajax request, based on data it retrieves from a database, or decoding the JSON in some ajax request, and then storing the relevant data back into its database.

Do you really have a "JSON file", and if so, where does it exist and where did you get it from? Do you have a JSON-format string, that you need to parse, mainpulate, and turn back into a new JSON-format string? Do you need to get JSON from the server, and modify it and then send it back to the server? Or is your "JSON file" actually just a JavaScript object, that you simply need to manipulate with normal JavaScript logic?

For create UIButton from storyboard: 1 - Drag UIButton object from Object Library to ViewController in storyboard file 2 - Show Assistant editor 3 - Drag with right click from UIButton create above into your class. The result is the following:

@IBAction func buttonActionFromStoryboard(sender: UIButton)
{
    println("Button Action From Storyboard")
}

For create UIButton programmatically: 1- Write into "override func viewDidLoad()":

        let uiButton    = UIButton.buttonWithType(UIButtonType.System) as UIButton
        uiButton.frame  = CGRectMake(16, 116, 288, 30)
        uiButton.setTitle("Second", forState: UIControlState.Normal);
        uiButton.addTarget(self, action: "buttonActionFromCode:", forControlEvents: UIControlEvents.TouchUpInside)
        self.view.addSubview(uiButton)

2- add the IBAction func:

@IBAction func buttonActionFromCode(sender:UIButton)
{
    println("Button Action From Code")
}

An Injection Framework is an implementation of the Factory Pattern.

It all depends upon your requirements. If you have need to implement the factory pattern in an application, it's highly likely your requirements will be met by one of the myriad of injection framework implementations out there.

You should only roll out your own solution if your requirements cannot be met by any of the 3rd party frameworks. The more code you write, the more you code you have to maintain. Code is a liability not an asset.

Arguments over which implementation you should use is not as fundamentally important as understanding the architectural needs of your application.

Typescript: following should work,

export const getTimeBetweenDates = ({
  until,
  format
}: {
  until: number;
  format: 'seconds' | 'minutes' | 'hours' | 'days';
}): number => {
  const date = new Date();
  const remainingTime = new Date(until * 1000);
  const getFrom = moment([date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate()]);
  const getUntil = moment([remainingTime.getUTCFullYear(), remainingTime.getUTCMonth(), remainingTime.getUTCDate()]);
  const diff = getUntil.diff(getFrom, format);
  return !isNaN(diff) ? diff : null;
};

The "uni" in unistd stands for "UNIX" - you won't find it on a Windows system.

Most widely used, portable libraries should offer alternative builds or detect the platform and only try to use headers/functions that will be provided, so it's worth checking documentation to see if you've missed some build step - e.g. perhaps running "make" instead of loading a ".sln" Visual C++ solution file.

If you need to fix it yourself, remove the include and see which functions are actually needed, then try to find a Windows equivalent.

Here is how I solved my problem:

Directive

app.directive("directive_name", function(){
    return {
        restrict: 'E',
        transclude: true,
        template: function(elem, attr){
           return '<div><h2>{{'+attr.scope+'}}</h2></div>';
        },
        replace: true
    };
})

Controller

$scope.building = function(data){
    var chart = angular.element(document.createElement('directive_name'));
    chart.attr('scope', data);
    $compile(chart)($scope);
    angular.element(document.getElementById('wrapper')).append(chart);
  }

I now can use different scopes through the same directive and append them dynamically.

Or try:

$("#datetimepicker").data().date;

Is correct?

<script>
$( "#box" ).one( "click", function() {
  $( this ).css( "width", "+=200" );
});
</script>

Execute the GetEventIdsByEventDate() method and save the results in a variable, and then you can use the .Contains() method

In C# 6:

It is now possible to declare the auto-properties just as a field:

public string FirstName { get; set; } = "Ropert";

Read-Only Auto-Properties

public string FirstName { get;} = "Ropert";

Generally, you can use the func(*tuple) syntax. You can even pass a part of the tuple, which seems like what you're trying to do here:

t = (2010, 10, 2, 11, 4, 0, 2, 41, 0)
dt = datetime.datetime(*t[0:7])

This is called unpacking a tuple, and can be used for other iterables (such as lists) too. Here's another example (from the Python tutorial):

>>> range(3, 6)             # normal call with separate arguments
[3, 4, 5]
>>> args = [3, 6]
>>> range(*args)            # call with arguments unpacked from a list
[3, 4, 5]

This is because PDO treats "localhost" host specially:

Note: Unix only: When the host name is set to "localhost", then the connection to the server is made thru a domain socket. If PDO_MYSQL is compiled against libmysqlclient then the location of the socket file is at libmysqlclient's compiled in location. If PDO_MYSQL is compiled against mysqlnd a default socket can be set thru the pdo_mysql.default_socket setting.

(from http://php.net/manual/en/ref.pdo-mysql.connection.php)

Changing localhost to 127.0.0.1 will "force" the use of TCP.

Note: mysqli_connect is working fine with localhost.

If obj is of type int[] say, then that will have an array Class but not be an instance of Object[]. So what do you want to do with obj. If you are going to cast it, go with instanceof. If you are going to use reflection, then use .getClass().isArray().

If you got XDebug installed, you can use it's var_dump replacement. Quoting:

Xdebug replaces PHP's var_dump() function for displaying variables. Xdebug's version includes different colors for different types and places limits on the amount of array elements/object properties, maximum depth and string lengths. There are a few other functions dealing with variable display as well.

You will likely want to tweak a few of the following settings:

There is a number of settings that control the output of Xdebug's modified var_dump() function: xdebug.var_display_max_children, xdebug.var_display_max_data and xdebug.var_display_max_depth. The effect of these three settings is best shown with an example. The script below is run four time, each time with different settings. You can use the tabs to see the difference.

But keep in mind that XDebug will significantly slow down your code, even when it's just loaded. It's not advisable to run in on production servers. But hey, you are not var_dumping on production servers anyway, are you?

have you considered using a LinkedHashMap<>()..?

  public static void main(String[] args) {
    Map<Object, Object> handler = new LinkedHashMap<Object, Object>();
    handler.put("item", "Value");
    handler.put(2, "Movies");
    handler.put("isAlive", true);

    for (Map.Entry<Object, Object> entrY : handler.entrySet())
        System.out.println(entrY.getKey() + ">>" + entrY.getValue());

    List<Map.Entry<String, Integer>> entries = new ArrayList<Map.Entry<String, Integer>>();
    Collections.sort(entries, new Comparator<Map.Entry<String, Integer>>() {
        public int compare(Map.Entry<String, Integer> a,
                Map.Entry<String, Integer> b) {
            return a.getValue().compareTo(b.getValue());
        }
    });
}

results into an organized linked object.

 item>>Value
 2>>Movies
 isAlive>>true

check the sorting part picked from here..

On MacOS Catalina, open terminal, follow this step:

1. Create zshrc file: touch ~/.zshrc
2. Open file zshrc: open ~/.zshrc
3. Insert this line to file, type: export PATH="/Users/YOUR_NAME/Downloads/flutter/bin:$PATH" Save file and close. (explain: YOUR_NAME -is name of user your Mac, Downloads -is folder i put folder flutter)

You can do this with CSS Variable

.box-shadow {
    --box-shadow-color: #000; /* Declaring the variable */
    width: 30px;                
    height: 30px;
    box-shadow: 1px 1px 25px var(--box-shadow-color); /* Calling the variable */

}

.box-shadow:hover  {
    --box-shadow-color: #ff0000; /* Changing the value of the variable */
}

To anyone else who finds this older question, you can now download all old versions.

Xcode -> Preferences -> Components (Click on Simulators tab).

Install all the versions you want/need.

To show all installed simulators:

Target -> In dropdown "deployment target" choose the installed version with lowest version nr.

You should now see all your available simulators in the dropdown.

You most certainly have a databases tab in sql developer (all versions I've used in the past have this). Maybe check again? Perhaps, you're looking in the wrong location.

On a mac, the preferences is under "Oracle SQL Developer" (top left) -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

On windows (going from memory so might have to search if this isn't correct) Tools -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

I have answered this question here: How to resize images proportionally / keeping the aspect ratio?. I am copying it here because I really think it is a very reliable method :)

 /**
  * Conserve aspect ratio of the original region. Useful when shrinking/enlarging
  * images to fit into a certain area.
  *
  * @param {Number} srcWidth width of source image
  * @param {Number} srcHeight height of source image
  * @param {Number} maxWidth maximum available width
  * @param {Number} maxHeight maximum available height
  * @return {Object} { width, height }
  */
function calculateAspectRatioFit(srcWidth, srcHeight, maxWidth, maxHeight) {

    var ratio = Math.min(maxWidth / srcWidth, maxHeight / srcHeight);

    return { width: srcWidth*ratio, height: srcHeight*ratio };
 }

An example statement that uses a sub-select :

select * into MyNewTable
from
(
select 
  * 
from 
[SomeOtherTablename]
where 
  EventStartDatetime >= '01/JAN/2018' 
)
) mysourcedata
;

note that the sub query must be given a name .. any name .. e.g. above example gives the subquery a name of mysourcedata. Without this a syntax error is issued in SQL*server 2012.

The database should reply with a message like: (9999 row(s) affected)

This should work for you

 public class MyActivity extends Activity {

    protected ProgressDialog mProgressDialog;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        populateTable();
    }

    private void populateTable() {
        mProgressDialog = ProgressDialog.show(this, "Please wait","Long operation starts...", true);
        new Thread() {
            @Override
            public void run() {

                doLongOperation();
                try {

                    // code runs in a thread
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            mProgressDialog.dismiss();
                        }
                    });
                } catch (final Exception ex) {
                    Log.i("---","Exception in thread");
                }
            }
        }.start();

    }

    /** fake operation for testing purpose */
    protected void doLongOperation() {
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
        }

    }
}

Only use .then()

These are the disadvantages of .done()

• can not be chained
• block resolve() call (all .done() handlers will be executed synchronous)
• resolve() might get an exception from registered .done() handlers(!)
• an exception in a .done() half-kills the deferred:
  • further .done() handlers will be silently skipped

I thought temporarily that .then(oneArgOnly) always requires .catch() so that no exception gets silently ignored, but that is not true any more: the unhandledrejection event logs unhandled .then() exceptions on the console (as default). Very reasonable! No reason left to use .done() at all.

Proof

The following code snippet reveals, that:

• all .done() handlers will be called synchronous at point of resolve()
  • logged as 1, 3, 5, 7
  • logged before the script falls through bottom
• exception in a .done() influences resolve() caller
  • logged via catch around resolve()
• exception breaks promise from further .done() resolution
  • 8 and 10 are not logged!
• .then() has none of these problems
  • logged as 2, 4, 6, 9, 11 after thread turns idle
  • (snippet environment has no unhandledrejection is seems)

Btw, exceptions from .done() can’t be properly caught: because of the synchronous pattern of .done(), the error is either thrown at the point of .resolve() (might be library code!) or at the .done() call which attaches the culprit if the deferred is already resolved.

I tried above samples but not working for me. The simplest solution is working for me awesome:

<RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#fff" >
        <Spinner
            android:id="@+id/spinner1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:entries="@array/Area"/>
    </RelativeLayout>

Promise - Provide a single future value. Not lazy . Not cancel-able. It will either reject or resolve.

Observable - Provide multiple future value. Lazy . Cancel-able . It provide other methods live map,filter,reduce.

The first line moves the cursor to the last non-empty row in the column. The second line prints that columns row.

Selection.End(xlDown).Select
MsgBox(ActiveCell.Row)

Set the second function parameter to true if you require an associative array

Some versions of php require a 2nd paramter of true if you require an associative array

$json  = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$array = json_decode( $json, true );

You could do:

var numberOfChecked = $('input:checkbox:checked').length;
var totalCheckboxes = $('input:checkbox').length;
var numberNotChecked = totalCheckboxes - numberOfChecked;

EDIT

Or even simple

var numberNotChecked = $('input:checkbox:not(":checked")').length;

No there isn't. DateTime represents some point in time that is composed of a date and a time. However, you can retrieve the date part via the Date property (which is another DateTime with the time set to 00:00:00).

And you can retrieve individual date properties via Day, Month and Year.

Hey guys it exist a much more sexy tool for a developper to have a look into a Directory, whatever the Directory is (Active-Directory, OpenLDAP, eDirectory ...) its name is Apache Directory studio, it works in the same way on the top of java in Windows or in Linux. It's a kind of universal LDP.EXE for those who know this tool on Windows Servers. It allows to create LDIF files and also to browse the SCHEMA.

First off, if you're starting a new project, go with Entity Framework ("EF") - it now generates much better SQL (more like Linq to SQL does) and is easier to maintain and more powerful than Linq to SQL ("L2S"). As of the release of .NET 4.0, I consider Linq to SQL to be an obsolete technology. MS has been very open about not continuing L2S development further.

1) Performance

This is tricky to answer. For most single-entity operations (CRUD) you will find just about equivalent performance with all three technologies. You do have to know how EF and Linq to SQL work in order to use them to their fullest. For high-volume operations like polling queries, you may want to have EF/L2S "compile" your entity query such that the framework doesn't have to constantly regenerate the SQL, or you can run into scalability issues. (see edits)

For bulk updates where you're updating massive amounts of data, raw SQL or a stored procedure will always perform better than an ORM solution because you don't have to marshal the data over the wire to the ORM to perform updates.

2) Speed of Development

In most scenarios, EF will blow away naked SQL/stored procs when it comes to speed of development. The EF designer can update your model from your database as it changes (upon request), so you don't run into synchronization issues between your object code and your database code. The only time I would not consider using an ORM is when you're doing a reporting/dashboard type application where you aren't doing any updating, or when you're creating an application just to do raw data maintenance operations on a database.

3) Neat/Maintainable code

Hands down, EF beats SQL/sprocs. Because your relationships are modeled, joins in your code are relatively infrequent. The relationships of the entities are almost self-evident to the reader for most queries. Nothing is worse than having to go from tier to tier debugging or through multiple SQL/middle tier in order to understand what's actually happening to your data. EF brings your data model into your code in a very powerful way.

4) Flexibility

Stored procs and raw SQL are more "flexible". You can leverage sprocs and SQL to generate faster queries for the odd specific case, and you can leverage native DB functionality easier than you can with and ORM.

5) Overall

Don't get caught up in the false dichotomy of choosing an ORM vs using stored procedures. You can use both in the same application, and you probably should. Big bulk operations should go in stored procedures or SQL (which can actually be called by the EF), and EF should be used for your CRUD operations and most of your middle-tier's needs. Perhaps you'd choose to use SQL for writing your reports. I guess the moral of the story is the same as it's always been. Use the right tool for the job. But the skinny of it is, EF is very good nowadays (as of .NET 4.0). Spend some real time reading and understanding it in depth and you can create some amazing, high-performance apps with ease.

EDIT: EF 5 simplifies this part a bit with auto-compiled LINQ Queries, but for real high volume stuff, you'll definitely need to test and analyze what fits best for you in the real world.

If you are using Bootstrap 3 and Less you could apply the responsive tables to all resolutions by updatingthe file:

tables.less

or overwriting this part:

@media (max-width: @screen-xs) {
  .table-responsive {
    width: 100%;
    margin-bottom: 15px;
    overflow-y: hidden;
    overflow-x: scroll;
    border: 1px solid @table-border-color;

    // Tighten up spacing and give a background color
    > .table {
      margin-bottom: 0;
      background-color: #fff;

      // Ensure the content doesn't wrap
      > thead,
      > tbody,
      > tfoot {
        > tr {
          > th,
          > td {
            white-space: nowrap;
          }
        }
      }
    }

    // Special overrides for the bordered tables
    > .table-bordered {
      border: 0;

      // Nuke the appropriate borders so that the parent can handle them
      > thead,
      > tbody,
      > tfoot {
        > tr {
          > th:first-child,
          > td:first-child {
            border-left: 0;
          }
          > th:last-child,
          > td:last-child {
            border-right: 0;
          }
        }
        > tr:last-child {
          > th,
          > td {
            border-bottom: 0;
          }
        }
      }
    }
  }
}

With:

@media (max-width: @screen-lg) {
  .table-responsive {
    width: 100%;
...

Note how I changed the first line @screen-XX value.

I know making all tables responsive may not sound that good, but I found it extremely useful to have this enabled up to LG on large tables (lots of columns).

Hope it helps someone.

I solve this problem in next way:

sudo apt-get install redis-server

then run command to confirm that everything ok:

sudo service redis-server status

And the output will be: redis-server is running - that means that the problem is solved.

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

It looks like the best approach is to use:

ContextCompat.getColor(context, R.color.color_name)

eg:

yourView.setBackgroundColor(ContextCompat.getColor(applicationContext,
                            R.color.colorAccent))

This will choose the Marshmallow two parameter method or the pre-Marshmallow method appropriately.

An easy way to add buttons to Comment or Un-Comment a code block is:

• Go to View-Toolbars-Customise
• Select the Command tab
• Select the Edit Category on the left
• Drag the “Comment Block” and “Uncomment Block” icons onto your toolbar.

Here is what you can do:-

Exim SSL certificates

By default, the /etc/exim.conf will use the cert/key files:

/etc/exim.cert
/etc/exim.key

so if you're wondering where to set your files, that's where.

They're controlled by the exim.conf's options:

tls_certificate = /etc/exim.cert
tls_privatekey = /etc/exim.key

Intermediate Certificates

If you have a CA Root certificate (ca bundle, chain, etc.) you'll add the contents of your CA into the exim.cert, after your actual certificate.

Probably a good idea to make sure you have a copy of everything elsewhere in case you make an error.

Dovecot and ProFtpd should also read it correctly, so dovecot no longer needs the ssl_ca option. So for both cases, there is no need to make any changes to either the exim.conf or dovecot.conf(/etc/dovecot/conf/ssl.conf)

As already mentioned, you can simply cast long to double. But be careful with long to double conversion because long to double is a narrowing conversion in java.

Conversion from type double to type long requires a nontrivial translation from a 64-bit floating-point value to the 64-bit integer representation. Depending on the actual run-time value, information may be lost.

e.g. following program will print 1 not 0

    long number = 499999999000000001L;
    double converted = (double) number;
    System.out.println( number - (long) converted);

Working with just one selector:

select {
    width: 268px;
    padding: 5px;
    font-size: 16px;
    line-height: 1;
    border: 0;
    border-radius: 5px;
    height: 34px;
    background: url(http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png) no-repeat right #ddd;
    -webkit-appearance: none;
    background-position-x: 244px;
}
