Programs & Examples On #Magento

You can also disable the menu items through the backend, without having to touch any code. Go into:

System > Configuration > Advanced

You'll be presented with a long list of options. Here are some of the key modules to set to 'Disabled' :

Mage_Downloadable -> My Downloadable Products
Mage_Newsletter -> My Newsletter
Mage_Review -> My Reviews
Mage_Tag -> My Tags
Mage_Wishlist -> My Wishlist

I also disabled Mage_Poll, as it has a tendency to show up in other page templates and can be annoying if you're not using it.

A good alternative is this:

find . -type f | xargs chmod -v 644

and for directories:

find . -type d | xargs chmod -v 755

and to be more explicit:

find . -type f | xargs -I{} chmod -v 644 {}

For formatting the price in another currency than the current one:

Mage::app()->getLocale()->currency('EUR')->toCurrency($price);

(string)Mage::helper('catalog/image')->init($product, 'image');

this will give you image url, even if image hosted on CDN.

for example if you want to get EMAIL ADDRESS from config->store email addresses. You can specify from wich store you will want the address:

$store=Mage::app()->getStore()->getStoreId(); 
/* Sender Name */
Mage::getStoreConfig('trans_email/ident_general/name',$store); 
/* Sender Email */
Mage::getStoreConfig('trans_email/ident_general/email',$store);

I will rather recommend Mage2Gen, this will help you generate the boilerplate and you can just focus on the core business logic. it just helps speed up the things.

In Magento 1.9.4.0 and maybe all versions in 1.x use:

Mage::getStoreConfig('general/store_information/address');

and the following params, it depends what you want to get:

• general/store_information/name
• general/store_information/phone
• general/store_information/merchant_country
• general/store_information/address
• general/store_information/merchant_vat_number

After a long time suffering from it in PHPunit...

For those using namespace, which is very common with Frameworks or CMS, a good check in addition to seeing if php-xml is installed and active, is to remember to declare the DOMDocument after the namespace:

namespace YourNameSpace\YourNameSpace;

use DOMDocument; //<--- here, check this!

In the layout (app/design/frontend/your_theme/layout/default.xml):

<default>
    <cms_page> <!-- need to be redefined for your needs -->
        <reference name="content">
            <block type="cms/block" name="cms_newest_product" as="cms_newest_product">
                <action method="setBlockId"><block_id>newest_product</block_id></action>
            </block>
        </reference>
    </cms_page>
</default>

In your phtml template:

<?php echo $this->getChildHtml('newest_product'); ?>

Don't forget about cache cleaning.

I think it help.

You can Implement this also:- setPage(1, n); where, n = any number.

$products = Mage::getResourceModel('catalog/product_collection')
                ->addAttributeToSelect('*')
                ->addAttributeToSelect(array('name', 'price', 'small_image'))
                ->addFieldToFilter('visibility', Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH) //visible only catalog & searchable product
                ->addAttributeToFilter('status', 1) // enabled
                ->setStoreId($storeId)
                ->setOrder('created_at', 'desc')
                ->setPage(1, 6);

You can do this thing:

Go to http://localhost/magento/downloader url. Here I am running the magento store on my localhost. Now you can login to magento connect manager and uninstall the extension which you installed previously.

Hope this works !!!!!

Thanks.

I have added line

$this->_productCollection->addAttributeToSelect('releasedate');

in

app/code/core/Mage/Catalog/Block/Product/List.php on line 95

in function _getProductCollection()

and then call it in

app/design/frontend/default/hellopress/template/catalog/product/list.phtml

By writing code

<div><?php echo $this->__('Release Date: %s', $this->dateFormat($_product->getReleasedate())) ?>
</div>

Now it is working in Magento 1.4.x

This is how I got it corrected(Hope will help you guys):

1. Use the following code in your index.php file

   ini_set('error_reporting', E_ERROR);
   register_shutdown_function("fatal_handler");
   function fatal_handler() {
       $error = error_get_last();
       echo("<pre>");
       print_r($error);
   }
   

2. In my case it tolde me that error/503.php was unavailable.

3.The issue was with testimonial extension I used(http://www.magentocommerce.com/magento-connect/magebuzz-free-testimonial.html)

4. I deleted the testimonial.xml file in my app/etc/modules/testimoanial.xml.
5. delete “maintenance.flag" file.

your column value is already in database table it means your table column is Unique you should change your value and try again

Follow the below steps it will helps you.

step 1: Go to to your site root folder and you can find the .htaccess file there. Open it with a text editor and find the line #RewriteBase /magento/. Just replace it with #RewriteBase / take out just the 'magento/'

step 2: Then go to your admin panel and enable the Rewrites(set yes for Use Web Server Rewrites). You can find it at System->Configuration->Web->Search Engine Optimization.

step 3: Then go to Cache management page (system cache management ) and refresh your cache and refresh to check the site.

Rename pub/local.xml.sample into local.xml . then i will show you exactly error.

You can get attribute value by following way

$model = Mage::getResourceModel('catalog/product');
$attribute_value = $model->getAttributeRawValue($productId, 'attribute_code', $storeId);

Try below code to get currently loaded product id:

$product_id = $this->getProduct()->getId();

When you don’t have access to $this, you can use Magento registry:

$product_id = Mage::registry('current_product')->getId();

Also for product type i think

$product = Mage::getModel('catalog/product')->load($product_id); 

$productType = $product->getTypeId();

Cleaning the Magento Logs using SSH :

login to shell(SSH) panel and go with root/shell folder.

execute the below command inside the shell folder

php -f log.php clean

enter this command to view the log data's size

php -f log.php status

This method will help you to clean the log data's very easy way.

In my apache error log, I saw:

[Tue Feb 16 14:55:02 2010] [notice] child pid 9985 exit signal File size limit exceeded (25)

So I, removed all the contents of my largest log file 2.1GB /var/log/system.log. Now everything works.

To create your custom log file, try this code

Mage::log('your debug message', null, 'yourlog_filename.log');

Thanks to all, for me this solution worked: Magento 404 page in backoffice after login

I also tried to get the field1 = 'a' OR field2 = 'b'

Your code didn't work for me.

Here is my solution

$results = Mage::getModel('xyz/abc')->getCollection();
$results->addFieldToSelect('name');
$results->addFieldToSelect('keywords');
$results->addOrder('name','ASC');
$results->setPageSize(5);

$results->getSelect()->where("keywords like '%foo%' or additional_keywords  like '%bar%'");

$results->load();

echo json_encode($results->toArray());

It gives me

SELECT name, keywords FROM abc WHERE keywords like '%foo%' OR additional_keywords like '%bar%'.

It is maybe not the "magento's way" but I was stuck 5 hours on that.

Hope it will help

For username is same with some modification:

$user=$this->__('Welcome, %s!', Mage::getSingleton('customer/session')->getCustomer()->getName());
echo $user;

To use it in phtml apply :

echo $this->getSkinUrl('your_image_folder_under_skin/image_name.png');

To use skin path in cms page :

<img style="width: 715px; height: 266px;" src="{{skin url=images/banner1.jpg}}" alt="title" />

This part====> {{skin url=images/banner1.jpg}}

I hope this will help you.

I'm not sure there is point in such conversion (yes, many do it, but mostly to force a square peg through round hole) -- there is structural impedance mismatch, and conversion is lossy. So I would recommend against such format-to-format transformations.

But if you do it, first convert from json to object, then from object to xml (and vice versa for reverse direction). Doing direct transformation leads to ugly output, loss of information, or possibly both.

This is how managed to change my data table row background (DataTables 1.10.19)

$('#memberList').DataTable({
    "processing": true,
    "serverSide": true,
    "pageLength":25,
    "ajax":{
        "dataType": "json",
        "type": "POST",
        "url": mainUrl+"/getMember",
       },
    "columns": [
        { "data": "id" },
        { "data": "name" },
        { "data": "email" },
        { "data": "phone" },
        { "data": "country_id" },
        { "data": "created_at" },
        { "data": "action" },
    ],
    "fnRowCallback": function( nRow, aData, iDisplayIndex, iDisplayIndexFull ) {
        switch(aData['country_id']){
            case 1:
                $('td', nRow).css('background-color', '#dacfcf')
                break;
        }
    }
});

You can use fnRowCallback method function to change the background.

Have a look at GROUP_CONCAT if your MySQL version (4.1) supports it. See the documentation for more details.

It would look something like:

  SELECT GROUP_CONCAT(hobbies SEPARATOR ', ') 
  FROM peoples_hobbies 
  WHERE person_id = 5 
  GROUP BY 'all';

It depends on how the code in the first file is structured.

If it's just a bunch of functions, like:

# first.py
def foo(): print("foo")
def bar(): print("bar")

Then you could import it and use the functions as follows:

# second.py
import first

first.foo()    # prints "foo"
first.bar()    # prints "bar"

or

# second.py
from first import foo, bar

foo()          # prints "foo"
bar()          # prints "bar"

or, to import all the names defined in first.py:

# second.py
from first import *

foo()          # prints "foo"
bar()          # prints "bar"

Note: This assumes the two files are in the same directory.

It gets a bit more complicated when you want to import names (functions, classes, etc) from modules in other directories or packages.

Scanner scanner = new Scanner(System.in);
int employeeId, supervisorId;
String name;
System.out.println("Enter employee ID:");
employeeId = scanner.nextInt();
scanner.nextLine(); //This is needed to pick up the new line
System.out.println("Enter employee name:");
name = scanner.nextLine();
System.out.println("Enter supervisor ID:");
supervisorId = scanner.nextInt();

Calling nextInt() was a problem as it didn't pick up the new line (when you hit enter). So, calling scanner.nextLine() after that does the work.

This creates dictionary of text (string):

Map<String, String> dictionary = new HashMap<String, String>();

you then use it as a:

dictionary.put("key", "value");
String value = dictionary.get("key");

Works but gives an error you need to keep the constructor class same as the declaration class. I know it inherits from the parent class but, unfortunately it gives an error on runtime.

Map<String, String> dictionary = new Map<String, String>();

This works properly.

Maybe someone can use it. Find all files which were modified within a certain time frame recursively, just run:

find . -type f -newermt "2013-06-01" \! -newermt "2013-06-20"

SQL Server Reporting Services (SSRS)
SSRS can remain active even if you uninstall SQL Server.
To stop the service:

Open SQL Server Configuration Manager. Select “SQL Server Services” in the left-hand pane. Double-click “SQL Server Reporting Services”. Hit Stop. Switch to the Service tab and set the Start Mode to “Manual”.

Skype
Irritatingly, Skype can switch to port 80. To disable it, select
Tools > Options > Advanced > Connection then uncheck
“Use port 80 and 443 as alternatives for incoming connections”.

IIS (Microsoft Internet Information Server)

For Windows 7 (or vista) its the most likely culprit. You can stop the service from the command line.

Open command line cmd.exe and type:

net stop was /y

For older versions of Windows type:

net stop iisadmin /y

Other

If this does not solve the problem further detective work is necessary if IIS, SSRS and Skype are not to blame. Enter the following on the command line:

netstat -ao

The active TCP addresses and ports will be listed. Locate the line with local address “0.0.0.0:80" and note the PID value. Start Task Manager. Navigate to the Processes tab and, if necessary, click View > Select Columns to ensure “PID (Process Identifier)” is checked. You can now locate the PID you noted above. The description and properties should help you determine which application is using the port.

I know this question is asking about jquery, but for those people using jqueryui, there are constants for many of the keycodes:

$.ui.keyCode.ESCAPE

http://api.jqueryui.com/jQuery.ui.keyCode/

You can use Processing library: https://processing.org/reference/PGraphics.html

There is a method called triangle():

g.triangle(x1,y1,x2,y2,x3,y3)

Use this

openssl ciphers -v | awk '{print $2}' | sort | uniq

I think this is what you're looking for. NEW_BAL is the sum of QTYs subtracted from the balance:

SELECT   master_table.ORDERNO,
         master_table.ITEM,
         SUM(master_table.QTY),
         stock_bal.BAL_QTY,
         (stock_bal.BAL_QTY - SUM(master_table.QTY)) AS NEW_BAL
FROM     master_table INNER JOIN
         stock_bal ON master_bal.ITEM = stock_bal.ITEM
GROUP BY master_table.ORDERNO,
         master_table.ITEM

If you want to update the item balance with the new balance, use the following:

UPDATE stock_bal
SET    BAL_QTY = BAL_QTY - (SELECT   SUM(QTY)
                            FROM     master_table
                            GROUP BY master_table.ORDERNO,
                                     master_table.ITEM)

This assumes you posted the subtraction backward; it subtracts the quantities in the order from the balance, which makes the most sense without knowing more about your tables. Just swap those two to change it if I was wrong:

(SUM(master_table.QTY) - stock_bal.BAL_QTY) AS NEW_BAL

Finally, I got a solution for reloading page once after two months research.

It works fine on my clientside JS project.

I wrote a function that below reloading page only once.

1) First getting browser domloading time

2) Get current timestamp

3) Browser domloading time + 10 seconds

4) If Browser domloading time + 10 seconds bigger than current now timestamp then page is able to be refreshed via "reloadPage();"

But if it's not bigger than 10 seconds that means page is just reloaded thus It will not be reloaded repeatedly.

5) Therefore if you call "reloadPage();" function in somewhere in your js file page will only be reloaded once.

Hope that helps somebody

// Reload Page Function //
                function reloadPage() {
                    var currentDocumentTimestamp = new Date(performance.timing.domLoading).getTime();
                    // Current Time //
                    var now = Date.now();
                    // Total Process Lenght as Minutes //
                    var tenSec = 10 * 1000;
                    // End Time of Process //
                    var plusTenSec = currentDocumentTimestamp + tenSec;
                    if (now > plusTenSec) {
                        location.reload();
                    }
                }


                // You can call it in somewhere //
                reloadPage();

Here are three different ways to do it:

Here's a working Demo in Fiddle Of All Three

Validation:

You can use native bootstrap validation states (No Custom CSS!):

<div class="form-group has-feedback">
    <label class="control-label" for="inputSuccess2">Name</label>
    <input type="text" class="form-control" id="inputSuccess2"/>
    <span class="glyphicon glyphicon-search form-control-feedback"></span>
</div>

For a full discussion, see my answer to Add a Bootstrap Glyphicon to Input Box

Input Group:

You can use the .input-group class like this:

<div class="input-group">
    <input type="text" class="form-control"/>
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

For a full discussion, see my answer to adding Twitter Bootstrap icon to Input box

Unstyled Input Group:

You can still use .input-group for positioning but just override the default styling to make the two elements appear separate.

Use a normal input group but add the class input-group-unstyled:

<div class="input-group input-group-unstyled">
    <input type="text" class="form-control" />
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

Then change the styling with the following css:

.input-group.input-group-unstyled input.form-control {
    -webkit-border-radius: 4px;
       -moz-border-radius: 4px;
            border-radius: 4px;
}
.input-group-unstyled .input-group-addon {
    border-radius: 4px;
    border: 0px;
    background-color: transparent;
}

Also, these solutions work for any input size

&lt = less than <, &gt = greater than >

A one-liner splitting d into chunks of size 20:

split(d, ceiling(seq_along(d)/20))

More details: I think all you need is seq_along(), split() and ceiling():

> d <- rpois(73,5)
> d
 [1]  3  1 11  4  1  2  3  2  4 10 10  2  7  4  6  6  2  1  1  2  3  8  3 10  7  4
[27]  3  4  4  1  1  7  2  4  6  0  5  7  4  6  8  4  7 12  4  6  8  4  2  7  6  5
[53]  4  5  4  5  5  8  7  7  7  6  2  4  3  3  8 11  6  6  1  8  4
> max <- 20
> x <- seq_along(d)
> d1 <- split(d, ceiling(x/max))
> d1
$`1`
 [1]  3  1 11  4  1  2  3  2  4 10 10  2  7  4  6  6  2  1  1  2

$`2`
 [1]  3  8  3 10  7  4  3  4  4  1  1  7  2  4  6  0  5  7  4  6

$`3`
 [1]  8  4  7 12  4  6  8  4  2  7  6  5  4  5  4  5  5  8  7  7

$`4`
 [1]  7  6  2  4  3  3  8 11  6  6  1  8  4

Open the Command Prompt and Type :

cd  c:\windows\assembly\GAC_MSIL 

xcopy . C:\GacDump /s /y

This should give the dump of the entire GAC

Enjoy!

When you need cookies from session to session, there is another way to do it. Use the Chrome options user-data-dir in order to use folders as profiles. I run:

# You need to: from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("user-data-dir=selenium") 
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("www.google.com")

Here you can do the logins that check for human interaction. I do this and then the cookies I need now every time I start the Webdriver with that folder everything is in there. You can also manually install the Extensions and have them in every session.

The second time I run, all the cookies are there:

# You need to: from selenium.webdriver.chrome.options import Options    
chrome_options = Options()
chrome_options.add_argument("user-data-dir=selenium") 
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("www.google.com") # Now you can see the cookies, the settings, extensions, etc., and the logins done in the previous session are present here. 

The advantage is you can use multiple folders with different settings and cookies, Extensions without the need to load, unload cookies, install and uninstall Extensions, change settings, change logins via code, and thus no way to have the logic of the program break, etc.

Also, this is faster than having to do it all by code.

Here is a solution without relying on any server-side control, just like OP has described in the question.

Client side HTML code:

<form action="upload.aspx" method="post" enctype="multipart/form-data">
    <input type="file" name="UploadedFile" />
</form>

Page_Load method of upload.aspx :

if(Request.Files["UploadedFile"] != null)
{
    HttpPostedFile MyFile = Request.Files["UploadedFile"];
    //Setting location to upload files
    string TargetLocation = Server.MapPath("~/Files/");
    try
    {
        if (MyFile.ContentLength > 0)
        {
            //Determining file name. You can format it as you wish.
            string FileName = MyFile.FileName;
            //Determining file size.
            int FileSize = MyFile.ContentLength;
            //Creating a byte array corresponding to file size.
            byte[] FileByteArray = new byte[FileSize];
            //Posted file is being pushed into byte array.
            MyFile.InputStream.Read(FileByteArray, 0, FileSize);
            //Uploading properly formatted file to server.
            MyFile.SaveAs(TargetLocation + FileName);
        }
    }
    catch(Exception BlueScreen)
    {
        //Handle errors
    }
}

Use getChildCount() and getChildAt(int index).

Example:

LinearLayout ll = …
final int childCount = ll.getChildCount();
for (int i = 0; i < childCount; i++) {
      View v = ll.getChildAt(i);
      // Do something with v.
      // …
}

You neglected to say which version of C you are concerned about. Let's assume it's this one:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf

As you can see by reading the specification, the standard definitions of true and false are 1 and 0, yes.

If your question is about a different version of C, or about non-standard definitions for true and false, then ask a more specific question.

Permission denied is a security so you need to add a "User" permission..

1. Right click you database(which is .mdf file) and then properties
2. Go to security tab
3. Click Continue button
4. Click Add button
5. Click Advance button
6. Another window will show, then you click the "Find Now" button on the right side.
7. On the fields below, go to the bottom most and click the "Users". Click OK.
8. Click the permission "Users" that you have been created, then Check the full control checkbox.

There you go. You have now permission to your database.

Note: The connection-string in the above questions is using SQL-server authentication. So, Before taking the above step, You have to login using windows-authentication first, and then you have to give permission to the user who is using sql-server authentication. Permission like "dbcreator".

if you login with SQL server authentication and trying to give permission to the user you logged in. it shows, permission denied error.

Pass in the straight XML instead of a dictionary.

SingleOrDefault: You're saying that "At most" there is one item matching the query or default FirstOrDefault: You're saying that there is "At least" one item matching the query or default

Say that out loud next time you need to choose and you shall likely choose wisely. :)

Use the display property

a{
    display: block;
}

This will make the link to display in new line

If you want to remove list styling, use

li{
    list-style: none;
}

Using $resource in AngularJS you can do:

task.service.js

$ngTask.factory("$taskService", [
    "$resource",
    function ($resource) {
        var taskModelUrl = 'api/task/';
        return {
            rest: {
                taskUpload: $resource(taskModelUrl, {
                    id: '@id'
                }, {
                    save: {
                        method: "POST",
                        isArray: false,
                        headers: {"Content-Type": undefined},
                        transformRequest: angular.identity
                    }
                })
            }
        };
    }
]);

And then use it in a module:

task.module.js

$ngModelTask.controller("taskController", [
    "$scope",
    "$taskService",
    function (
        $scope,
        $taskService,
    ) {
    $scope.saveTask = function (name, file) {
        var newTask,
            payload = new FormData();
        payload.append("name", name);
        payload.append("file", file);
        newTask = $taskService.rest.taskUpload.save(payload);
        // check if exists
    }
}

Use row_count - your_desired_offset

So if we had 10 rows and want to offset 3

 10 - 3 = 7

Now the query delete from table where this = that order asc limit 7 keeps the last 3, and order desc to keep the first 3:

$row_count - $offset = $limit

Delete from table where entry = criteria order by ts asc limit $limit

Can CSS be used to hide the scroll bar? How would you do this?

If you wish to remove vertical (and horizontal) scrollbars from a browser viewport, add:

style="position: fixed;"

to the <body> element.

Javascript:

document.body.style.position = 'fixed';

CSS:

body {
  position: fixed;
}

PDF2SVG version 6.0 from PDFTron does a reasonable job. It produces OpenType (.otf) fonts by default. Use --preserve_fontnames to preserve "the font/font-family naming scheme as obtained from the source file."

PDF2SVG is a commercial product, but you can download a free demo executable (which includes watermarks on the SVG output but doesn't otherwise restrict usage). There may be other PDFTron products that also extract fonts, but I only recently discovered PDF2SVG myself.

I think an enum can't be final, because under the hood compiler generates subclasses for each enum entry.

Add .done() to your function

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({                                            
         url: 'api.php',

As many have already stated, as much as you want to test the private methods you shouldn't hack your code or transpiler to make it work for you. Modern day TypeScript will deny most all of the hacks that people have provided so far.

Solution

TLDR; if a method should be tested then you should be decoupling the code into a class that you can expose the method to be public to be tested.

The reason you have the method private is because the functionality doesn't necessarily belong to be exposed by that class, and therefore if the functionality doesn't belong there it should be decoupled into it's own class.

Example

I ran across this article that does a great job of explaining how you should tackle testing private methods. It even covers some of the methods here and how why they're bad implementations.

https://patrickdesjardins.com/blog/how-to-unit-test-private-method-in-typescript-part-2

Note: This code is lifted from the blog linked above (I'm duplicating in case the content behind the link changes)

class User{
    public getUserInformationToDisplay(){
        //...
        this.getUserAddress();
        //...
    }

    private getUserAddress(){
        //...
        this.formatStreet();
        //...
    }
    private formatStreet(){
        //...
    }
}

class User{
    private address:Address;
    public getUserInformationToDisplay(){
        //...
        address.getUserAddress();
        //...
    }
}
class Address{
    private format: StreetFormatter;
    public format(){
        //...
        format.ToString();
        //...

Since Java 7

File file = Paths.get(url.toURI()).toFile();

Make SymbolIndexer( const SymbolIndexer& ) private. If you're assigning to a reference, you're not copying.

One shortcoming of the accepted solution is that its output is very python specific. I.e. its raw json output cannot be observed by a human or loaded by another language (e.g. javascript). example:

db = {
        "a": [ 44, set((4,5,6)) ],
        "b": [ 55, set((4,3,2)) ]
        }

j = dumps(db, cls=PythonObjectEncoder)
print(j)

Will get you:

{"a": [44, {"_python_object": "gANjYnVpbHRpbnMKc2V0CnEAXXEBKEsESwVLBmWFcQJScQMu"}], "b": [55, {"_python_object": "gANjYnVpbHRpbnMKc2V0CnEAXXEBKEsCSwNLBGWFcQJScQMu"}]}

I can propose a solution which downgrades the set to a dict containing a list on the way out, and back to a set when loaded into python using the same encoder, therefore preserving observability and language agnosticism:

from decimal import Decimal
from base64 import b64encode, b64decode
from json import dumps, loads, JSONEncoder
import pickle

class PythonObjectEncoder(JSONEncoder):
    def default(self, obj):
        if isinstance(obj, (list, dict, str, int, float, bool, type(None))):
            return super().default(obj)
        elif isinstance(obj, set):
            return {"__set__": list(obj)}
        return {'_python_object': b64encode(pickle.dumps(obj)).decode('utf-8')}

def as_python_object(dct):
    if '__set__' in dct:
        return set(dct['__set__'])
    elif '_python_object' in dct:
        return pickle.loads(b64decode(dct['_python_object'].encode('utf-8')))
    return dct

db = {
        "a": [ 44, set((4,5,6)) ],
        "b": [ 55, set((4,3,2)) ]
        }

j = dumps(db, cls=PythonObjectEncoder)
print(j)
ob = loads(j)
print(ob["a"])

Which gets you:

{"a": [44, {"__set__": [4, 5, 6]}], "b": [55, {"__set__": [2, 3, 4]}]}
[44, {'__set__': [4, 5, 6]}]

Note that serializing a dictionary which has an element with a key "__set__" will break this mechanism. So __set__ has now become a reserved dict key. Obviously feel free to use another, more deeply obfuscated key.

The problem you run into when setting width to 50% is the rounding of subpixels. If the width of your container is i.e. 99 pixels, a width of 50% can result in 2 containers of 50 pixels each.

Using float is probably easiest, and not such a bad idea. See this question for more details on how to fix the problem then.

If you don't want to use float, try using a width of 49%. This will work cross-browser as far as I know, but is not pixel-perfect..

html:

<div id="a">A</div>
<div id="b">B</div>

css:

#a, #b {
    width: 49%;
    display: inline-block; 
}
#a {background-color: red;}
#b {background-color: blue;}

I tend to prefer and to use property accessors:

• I can add logic if the need arises (as mentioned in the accepted answer).
• it allows me to call foo.getId() without initializing a proxy (important when using Hibernate, until HHH-3718 get resolved).

Drawback:

• it makes the code less readable, you have for example to browse a whole class to see if there are @Transient around there.

.net Framework allows PictureBox Control to Load Images from url

and Save image in Laod Complete Event

protected void LoadImage() {
 pictureBox1.ImageLocation = "PROXY_URL;}

void pictureBox1_LoadCompleted(object sender, AsyncCompletedEventArgs e) {
   pictureBox1.Image.Save(destination); }

You can actually chain multiple $lookup stages. Based on the names of the collections shared by profesor79, you can do this :

db.sivaUserInfo.aggregate([
    {
        $lookup: {
           from: "sivaUserRole",
           localField: "userId",
           foreignField: "userId",
           as: "userRole"
        }
    },
    {
        $unwind: "$userRole"
    },
    {
        $lookup: {
            from: "sivaUserInfo",
            localField: "userId",
            foreignField: "userId",
            as: "userInfo"
        }
    },
    {
        $unwind: "$userInfo"
    }
])

This will return the following structure :

{
    "_id" : ObjectId("56d82612b63f1c31cf906003"),
    "userId" : "AD",
    "phone" : "0000000000",
    "userRole" : {
        "_id" : ObjectId("56d82612b63f1c31cf906003"),
        "userId" : "AD",
        "role" : "admin"
    },
    "userInfo" : {
        "_id" : ObjectId("56d82612b63f1c31cf906003"),
        "userId" : "AD",
        "phone" : "0000000000"
    }
}

Maybe this could be considered an anti-pattern because MongoDB wasn't meant to be relational but it is useful.

First, uppercase MM are months and lowercase mm are minutes.

You have to pass CultureInfo.InvariantCulture to ToString to ensure that / as date separator is used since it would normally be replaced with the current culture's date separator:

MsgBox(dt.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture))

Another option is to escape that custom format specifier by embedding the / within ':

dt.ToString("dd'/'MM'/'yyyy")

MSDN: The "/" Custom Format Specifier:

The "/" custom format specifier represents the date separator, which is used to differentiate years, months, and days. The appropriate localized date separator is retrieved from the DateTimeFormatInfo.DateSeparator property of the current or specified culture.

I prefer to use ToString() and IFormatProvider.

double value = 100000.3
Console.WriteLine(value.ToString("0,0.00", new CultureInfo("en-US", false)));

Output: 10,000.30

Uncaught TypeError: undefined is not a function example_app.js:7

This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined.

So what's on example_app.js line 7? Looks like this:

var tasks = new ExampleApp.Collections.Tasks(data.tasks);

There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks is undefined.

So lets look at where that is declared:

var Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks. But you never add it to the ExampleApp.Collections object, a place you later expect it to be.

Change that to this, and I bet you'd be good.

ExampleApp.Collections.Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.

In Javascript, when you execute a function, it's evaluated like:

expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does

That expression can be complex. So when you see undefined is not a function it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.

And in this case, it was because you didn't put something where you thought you did.

You have two choices: stash your changes:

git stash

then later to get them back:

git stash apply

or put your changes on a branch so you can get the remote branch and then merge your changes onto it. That's one of the greatest things about git: you can make a branch, commit to it, then fetch other changes on to the branch you were on.

You say it doesn't make any sense, but you are only doing it so you can merge them at will after doing the pull. Obviously your other choice is to commit on your copy of the branch and then do the pull. The presumption is you either don't want to do that (in which case I am puzzled that you don't want a branch) or you are afraid of conflicts.

A generic exception catching mechanism would prove extremely useful.

Doubtful. You already know your code is broken, because it's crashing. Eating exceptions may mask this, but that'll probably just result in even nastier, more subtle bugs.

What you really want is a debugger...

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

The way I cam across this question was when I tried doing something similar where I was defining a function and it was being called with the array like others pointed out

You could do something like this however for this scenarios its less elegant compared to Sven's method.

sapply(a, function(x) afunc(x))

afunc<-function(a){
  if (a>0){
    a/sum(a)
  }
  else 1
}

Try the following syntax:

document.body.innerHTML += "<p>My new content</p>";

As clean as it could get and give scope of replacing with variables:

Select RIGHT(REPLICATE('0',6) + EmployeeID, 6) from dbo.RequestItems
WHERE ID=0

Enable all these from php.ini configuration file

extension=php_openssl.dll
extension=php_curl.dll
extension=php_xmlrpc.dll

Your original example works just fine for me:

<html>
<head>
</head>
<body>
<script>
var widthRange = new Array();
widthRange[46] = { sel:46, min:0,  max:52 };
widthRange[66] = { sel:66, min:52, max:70 };
widthRange[90] = { sel:90, min:70, max:94 };

var i = 1;
for (var key in widthRange)
{
    document.write("Key #" + i + " = " + key + "; &nbsp;&nbsp;&nbsp; min/max = " + widthRange[key].min + "/" + widthRange[key].max + "<br />");
    i++;
}
</script>
</html>

Results in the browser (Firefox 3.6.2 on Windows XP):

Key #1 = 46;     min/max = 0/52
Key #2 = 66;     min/max = 52/70
Key #3 = 90;     min/max = 70/94

A special case is when trying to assess if a boolean value is nil:

false.present? == false
false.blank? == true
false.nil? == false

In this case the recommendation would be to use .nil?

It's a "native (platform-specific) size integer." It's internally represented as void* but exposed as an integer. You can use it whenever you need to store an unmanaged pointer and don't want to use unsafe code. IntPtr.Zero is effectively NULL (a null pointer).

Maybe a little late to the party but why don't you use sessions to store your data?

bookingfacilities.php

session_start();
$_SESSION['form_date'] = $date;

successfulbooking.php

session_start();
$date = $_SESSION['form_date']; 

Nobody will see this.

Below you can find my implementation of gradient descent for linear regression problem.

At first, you calculate gradient like X.T * (X * w - y) / N and update your current theta with this gradient simultaneously.

• X: feature matrix
• y: target values
• w: weights/values
• N: size of training set

Here is the python code:

import pandas as pd
import numpy as np
from matplotlib import pyplot as plt
import random

def generateSample(N, variance=100):
    X = np.matrix(range(N)).T + 1
    Y = np.matrix([random.random() * variance + i * 10 + 900 for i in range(len(X))]).T
    return X, Y

def fitModel_gradient(x, y):
    N = len(x)
    w = np.zeros((x.shape[1], 1))
    eta = 0.0001

    maxIteration = 100000
    for i in range(maxIteration):
        error = x * w - y
        gradient = x.T * error / N
        w = w - eta * gradient
    return w

def plotModel(x, y, w):
    plt.plot(x[:,1], y, "x")
    plt.plot(x[:,1], x * w, "r-")
    plt.show()

def test(N, variance, modelFunction):
    X, Y = generateSample(N, variance)
    X = np.hstack([np.matrix(np.ones(len(X))).T, X])
    w = modelFunction(X, Y)
    plotModel(X, Y, w)


test(50, 600, fitModel_gradient)
test(50, 1000, fitModel_gradient)
test(100, 200, fitModel_gradient)

I would use list comprehension :

somelists = [
   [1, 2, 3],
   ['a', 'b'],
   [4, 5]
]

cart_prod = [(a,b,c) for a in somelists[0] for b in somelists[1] for c in somelists[2]]

To get body lines use escape()

body_line =  escape("\n");

so

href = "mailto:[email protected]?body=hello,"+body_line+"I like this.";

I've solved this issue adding user and password in Transport.send call:

Transport.send(msg, "user", "password");

According to this signature of the send function in javax.mail (from version 1.5):

public static void send(Message msg, String user, String password)

Also, if you use this signature it's not necessary to set up any Authenticator, and to set user and password in the Properties (only the host is needed). So your code could be:

private void sendMail(){
  try{
      Properties prop = System.getProperties();
      prop.put("mail.smtp.host", "yourHost");
      Session session = Session.getInstance(prop);
      Message msg = #createYourMsg(session, from, to, subject, mailer, yatta yatta...)#;
      Transport.send(msg, "user", "password");
  }catch(Exception exc) {
      // Deal with it! :)
  }
}

You can use this command: ECHO >> filename.txt

it will create a file with the given extension in the current folder.

UPDATE:

for an empty file use: copy NUL filename.txt

You may also use PSCredential.GetNetworkCredential() :

$SecurePassword = Get-Content C:\Users\tmarsh\Documents\securePassword.txt | ConvertTo-SecureString
$UnsecurePassword = (New-Object PSCredential "user",$SecurePassword).GetNetworkCredential().Password

You can do it using $.ajax or $.post

Using $.ajax :

    $.ajax({
      type: 'post',
      url: 'superman',
      data: { 
        'field1': 'hello', 
        'field2': 'hello1'
      },
      success: function (response) {
        alert(response.status);
      },
      error: function () {
        alert("error");
      }
   });

Using $.post :

    $.post('superman',
      { 
        'field1': 'hello', 
        'field2': 'hello1'
      },
      function (response, status) {
        alert(response.status);
      }
    );

New way: spotify/docker-gc play the trick.

 docker run --rm -v /var/run/docker.sock:/var/run/docker.sock -v /etc:/etc spotify/docker-gc

• Containers that exited more than an hour ago are removed.
• Images that don't belong to any remaining container after that are removed

It has supported environmental settings

Forcing deletion of images that have multiple tags

 FORCE_IMAGE_REMOVAL=1

Forcing deletion of containers

 FORCE_CONTAINER_REMOVAL=1 

Excluding Recently Exited Containers and Images From Garbage Collection

 GRACE_PERIOD_SECONDS=86400

This setting also prevents the removal of images that have been created less than GRACE_PERIOD_SECONDS seconds ago.

Dry run

 DRY_RUN=1

Cleaning up orphaned container volumes CLEAN_UP_VOLUMES=1

Reference: docker-gc

Old way to do:

delete old, non-running containers

 docker ps -a -q -f status=exited | xargs --no-run-if-empty docker rm
             OR 
 docker rm $(docker ps -a -q)

delete all images associated with non-running docker containers

 docker images -q | xargs --no-run-if-empty docker rmi

cleanup orphaned docker volumes for docker version 1.10.x and above

 docker volume ls -qf dangling=true | xargs -r docker volume rm

Based on time period

 docker ps -a | grep "weeks ago" | awk "{print $1}" | xargs --no-run-if-empty docker rm
 docker ps -a | grep "days ago" | awk "{print $1}" | xargs --no-run-if-empty docker rm
 docker ps -a | grep "hours ago" | awk "{print $1}" | xargs --no-run-if-empty docker rm

Here is a lengthy article on stdin, stdout and stderr:

• What Are stdin, stdout, and stderr on Linux?

To summarize:

Streams Are Handled Like Files

Streams in Linux—like almost everything else—are treated as though they were files. You can read text from a file, and you can write text into a file. Both of these actions involve a stream of data. So the concept of handling a stream of data as a file isn’t that much of a stretch.

Each file associated with a process is allocated a unique number to identify it. This is known as the file descriptor. Whenever an action is required to be performed on a file, the file descriptor is used to identify the file.

These values are always used for stdin, stdout, and stderr:

0: stdin
1: stdout
2: stderr

Ironically I found this question on stack overflow and the article above because I was searching for information on abnormal / non-standard streams. So my search continues.

Calling m.check(side), meaning you are running actual code, but you can't run code outside main() - you can only define variables. In C++, code can only appear inside function bodies or in variable initializes.

Answer for Python beginners

In simpler words:

1. The key= parameter of sort requires a key function (to be applied to be objects to be sorted) rather than a single key value and
2. that is just what operator.itemgetter(1) will give you: A function that grabs the first item from a list-like object.

(More precisely those are callables, not functions, but that is a difference that can often be ignored.)

First, keep in mind that, in its precise definition, a module is an object in the memory of a Python interpreter, often created by reading one or more files from disk. While we may informally call a disk file such as a/b/c.py a "module," it doesn't actually become one until it's combined with information from several other sources (such as sys.path) to create the module object.

(Note, for example, that two modules with different names can be loaded from the same file, depending on sys.path and other settings. This is exactly what happens with python -m my.module followed by an import my.module in the interpreter; there will be two module objects, __main__ and my.module, both created from the same file on disk, my/module.py.)

A package is a module that may have submodules (including subpackages). Not all modules can do this. As an example, create a small module hierarchy:

$ mkdir -p a/b
$ touch a/b/c.py

Ensure that there are no other files under a. Start a Python 3.4 or later interpreter (e.g., with python3 -i) and examine the results of the following statements:

import a
a                ? <module 'a' (namespace)>
a.b              ? AttributeError: module 'a' has no attribute 'b'
import a.b.c
a.b              ? <module 'a.b' (namespace)>
a.b.c            ? <module 'a.b.c' from '/home/cjs/a/b/c.py'>

Modules a and a.b are packages (in fact, a certain kind of package called a "namespace package," though we wont' worry about that here). However, module a.b.c is not a package. We can demonstrate this by adding another file, a/b.py to the directory structure above and starting a fresh interpreter:

import a.b.c
? ImportError: No module named 'a.b.c'; 'a.b' is not a package
import a.b
a                ? <module 'a' (namespace)>
a.__path__       ? _NamespacePath(['/.../a'])
a.b              ? <module 'a.b' from '/home/cjs/tmp/a/b.py'>
a.b.__path__     ? AttributeError: 'module' object has no attribute '__path__'

Python ensures that all parent modules are loaded before a child module is loaded. Above it finds that a/ is a directory, and so creates a namespace package a, and that a/b.py is a Python source file which it loads and uses to create a (non-package) module a.b. At this point you cannot have a module a.b.c because a.b is not a package, and thus cannot have submodules.

You can also see here that the package module a has a __path__ attribute (packages must have this) but the non-package module a.b does not.

This should make it seamless:

public static final <T> void swap (T[] a, int i, int j) {
  T t = a[i];
  a[i] = a[j];
  a[j] = t;
}

public static final <T> void swap (List<T> l, int i, int j) {
  Collections.<T>swap(l, i, j);
}

private void test() {
  String [] a = {"Hello", "Goodbye"};
  swap(a, 0, 1);
  System.out.println("a:"+Arrays.toString(a));
  List<String> l = new ArrayList<String>(Arrays.asList(a));
  swap(l, 0, 1);
  System.out.println("l:"+l);
}

If you just want to delete the address assigned to the user and not to affect on User entity class you should try something like that:

@Entity
public class User {
   @OneToMany(mappedBy = "addressOwner", cascade = CascadeType.ALL)
   protected Set<Address> userAddresses = new HashSet<>();
}

@Entity 
public class Addresses {
   @ManyToOne(cascade = CascadeType.REFRESH) @JoinColumn(name = "user_id")
   protected User addressOwner;
}

This way you dont need to worry about using fetch in annotations. But remember when deleting the User you will also delete connected address to user object.

Create the file! try:

mkdir -p .android && touch ~/.android/repositories.cfg

Upon being asked what you intend to do with the bytes, you responded:

I'm going to encrypt it. I can encrypt it without converting but I'd still like to know why encoding comes to play here. Just give me the bytes is what I say.

Regardless of whether you intend to send this encrypted data over the network, load it back into memory later, or steam it to another process, you are clearly intending to decrypt it at some point. In that case, the answer is that you're defining a communication protocol. A communication protocol should not be defined in terms of implementation details of your programming language and its associated runtime. There are several reasons for this:

• You may need to communicate with a process implemented in a different language or runtime. (This might include a server running on another machine or sending the string to a JavaScript browser client, for example.)
• The program may be re-implemented in a different language or runtime in the future.
• The .NET implementation might change the internal representation of strings. You may think this sounds farfetched, but this actually happened in Java 9 to reduce memory usage. There's no reason .NET couldn't follow suit. Skeet suggests that UTF-16 probably isn't optimal today give the rise of the emoji and other blocks of Unicode needing more than 2 bytes to represent as well, increasing the likelihood that the internal representation could change in the future.

For communicating (either with a completely disparate process or with the same program in the future), you need to define your protocol strictly to minimize the difficulty of working with it or accidentally creating bugs. Depending on .NET's internal representation is not a strict, clear, or even guaranteed to be consistent definition. A standard encoding is a strict definition that will not fail you in the future.

In other words, you can't satisfy your requirement for consistency without specifying an encoding.

You may certainly choose to use UTF-16 directly if you find that your process performs significantly better since .NET uses it internally or for any other reason, but you need to choose that encoding explicitly and perform those conversions explicitly in your code rather than depending on .NET's internal implementation.

So choose an encoding and use it:

using System.Text;

// ...

Encoding.Unicode.GetBytes("abc"); # UTF-16 little endian
Encoding.UTF8.GetBytes("abc")

As you can see, it's also actually less code to just use the built in encoding objects than to implement your own reader/writer methods.

As the update to the other answer suggests, the workaround of installing the old openssl101 brew will no longer work. For a right-now workaround, see this comment on dotnet/cli#3964.

The most relevant part of the issue copied here:

I looked into the other option that was suggested for setting the rpath on the library. I think the following is a better solution that will only effect this specific library.

sudo install_name_tool -add_rpath /usr/local/opt/openssl/lib /usr/local/share/dotnet/shared/Microsoft.NETCore.App/1.0.0/System.Security.Cryptography.Native.dylib

and/or if you have NETCore 1.0.1 installed perform the same command for 1.0.1 as well:

sudo install_name_tool -add_rpath /usr/local/opt/openssl/lib /usr/local/share/dotnet/shared/Microsoft.NETCore.App/1.0.1/System.Security.Cryptography.Native.dylib

In effect, rather than telling the operating system to always use the homebrew version of SSL and potentially causing something to break, we're telling dotnet how to find the correct library.

Also importantly, it looks like Microsoft are aware of the issue and and have both a) a somewhat immediate plan to mitigate as well as b) a long-term solution (probaby bundling OpenSSL with dotnet).

Another thing to note: /usr/local/opt/openssl/lib is where the brew is linked by default:

13:22 $ ls -l /usr/local/opt/openssl
lrwxr-xr-x  1 ben  admin  26 May 15 14:22 /usr/local/opt/openssl -> ../Cellar/openssl/1.0.2h_1

If for whatever reason you install the brew and link it in a different location, then that path is the one you should use as an rpath.

Once you've update the rpath of the System.Security.Cryptography.Native.dylib libray, you'll need to restart your interactive session (i.e., close your console and start another one).

If you're writing code that you envisage is going to be compiled on a wide variety of platforms, with a number of different compilers, then using these flags yourself will help to ensure you don't produce code that only compiles under GCC.

You can do something like this:

HTML:

<div class='div'>
<label>Something</label>
<input type='text' class='input'/>
<div>

CSS:

.div{
      margin-bottom: 10px;
      display: grid;
      grid-template-columns: 1fr 4fr;
}

.input{
       width: 50%;
}

Hope this helps ! :)

There are a couple of options:

1. Just after initialising DataTables, remove the sorting classes on the TD element in the TBODY.

2. Disable the sorting classes using http://datatables.net/ref#bSortClasses . Problem with this is that it will disable the sort classes for user sort requests - which might or might not be what you want.

3. Have your server output the table in your required sort order, and don't apply a default sort on the table (aaSorting:[]).

If you wish to inject pure function, instead of text, you can use this method:

function inject(){_x000D_
    document.body.style.backgroundColor = 'blue';_x000D_
}_x000D_
_x000D_
// this includes the function as text and the barentheses make it run itself._x000D_
var actualCode = "("+inject+")()"; _x000D_
_x000D_
document.documentElement.setAttribute('onreset', actualCode);_x000D_
document.documentElement.dispatchEvent(new CustomEvent('reset'));_x000D_
document.documentElement.removeAttribute('onreset');

And you can pass parameters (unfortunatelly no objects and arrays can be stringifyed) to the functions. Add it into the baretheses, like so:

function inject(color){_x000D_
    document.body.style.backgroundColor = color;_x000D_
}_x000D_
_x000D_
// this includes the function as text and the barentheses make it run itself._x000D_
var color = 'yellow';_x000D_
var actualCode = "("+inject+")("+color+")"; 

This may be created sql injection point "SQL Injection Piggy-backed Queries". attackers able to append multiple malicious sql statements. so do not append user inputs directly to the queries.

Security considerations

The API functions mysqli_query() and mysqli_real_query() do not set a connection flag necessary for activating multi queries in the server. An extra API call is used for multiple statements to reduce the likeliness of accidental SQL injection attacks. An attacker may try to add statements such as ; DROP DATABASE mysql or ; SELECT SLEEP(999). If the attacker succeeds in adding SQL to the statement string but mysqli_multi_query is not used, the server will not execute the second, injected and malicious SQL statement.

PHP Doc

Use the enumerate built-in function: http://docs.python.org/library/functions.html#enumerate

Coming from the embedded world, where even uclibc is not always available, and code like

uint64_t myval = 0xdeadfacedeadbeef; printf("%llx", myval);

is printing you crap or not working at all -- i always use a tiny helper, that allows me to dump properly uint64_t hex:

#include <stdlib.h>
#include <stdio.h>
#include <stdint.h>

char* ullx(uint64_t val)
{
    static char buf[34] = { [0 ... 33] = 0 };
    char* out = &buf[33];
    uint64_t hval = val;
    unsigned int hbase = 16;

    do {
        *out = "0123456789abcdef"[hval % hbase];
        --out;
        hval /= hbase;
    } while(hval);

    *out-- = 'x', *out = '0';

    return out;
}

This kind of error usually means that some parts of (JS) code were not loaded. That the state which is inside of ui-sref is missing.

There is a working example

I am not an expert in ionic, so this example should show that it would be working, but I used some more tricks (parent for tabs)

This is a bit adjusted state def:

.config(function($stateProvider, $urlRouterProvider){
  $urlRouterProvider.otherwise("/index.html");

    $stateProvider

    .state('app', {
      abstract: true,
      templateUrl: "tpl.menu.html",
    })

  $stateProvider.state('index', {
    url: '/',
    templateUrl: "tpl.index.html",
    parent: "app",
  });


  $stateProvider.state('register', {
    url: "/register",
    templateUrl: "tpl.register.html",
    parent: "app",
  });

  $urlRouterProvider.otherwise('/');
}) 

And here we have the parent view with tabs, and their content:

<ion-tabs class="tabs-icon-top">

  <ion-tab title="Index" icon="icon ion-home" ui-sref="index">
    <ion-nav-view name=""></ion-nav-view>
  </ion-tab>

  <ion-tab title="Register" icon="icon ion-person" ui-sref="register">
    <ion-nav-view name=""></ion-nav-view>
  </ion-tab>

</ion-tabs>

Take it more than an example of how to make it running and later use ionic framework the right way...Check that example here

Here is similar Q & A with an example using the named views (for sure better solution) ionic routing issue, shows blank page

Improved version with named views in a tab is here: http://plnkr.co/edit/Mj0rUxjLOXhHIelt249K?p=preview

  <ion-tab title="Index" icon="icon ion-home" ui-sref="index">
    <ion-nav-view name="index"></ion-nav-view>
  </ion-tab>

  <ion-tab title="Register" icon="icon ion-person" ui-sref="register">
    <ion-nav-view name="register"></ion-nav-view>
  </ion-tab>

targeting named views:

  $stateProvider.state('index', {
    url: '/',
    views: { "index" : { templateUrl: "tpl.index.html" } },
    parent: "app",
  });


  $stateProvider.state('register', {
    url: "/register",
    views: { "register" : { templateUrl: "tpl.register.html", } },
    parent: "app",
  });

The C99 stdint.h defines these:

• int8_t
• int16_t
• int32_t
• uint8_t
• uint16_t
• uint32_t

And, if the architecture supports them:

• int64_t
• uint64_t

There are various other integer typedefs in stdint.h as well.

If you're stuck without a C99 environment then you should probably supply your own typedefs and use the C99 ones anyway.

The uint32 and uint64 (i.e. without the _t suffix) are probably application specific.

From a background script you can listen to the chrome.tabs.onUpdated event and check the property changeInfo.status on the callback. It can be loading or complete. If it is complete, do the action.

Example:

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete') {

    // do your things

  }
})

Because this will probably trigger on every tab completion, you can also check if the tab is active on its homonymous attribute, like this:

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete' && tab.active) {

    // do your things

  }
})

For Laravel5 Since one uses

{!! Form::input('date', 'date_start', null , ['class' => 'form-control', 'id' => 'date_start', 'name' => 'date_start']) !!}

=> Chrome will force its datepicker. => if you take it away with css you will get the usual formatting errors!! (The specified value does not conform to the required format, "yyyy-MM-dd".)

SOLUTION:

$('input[type="date"]').attr('type','text');

$("#date_start").datepicker({
    autoclose: true,
    todayHighlight: true,
    dateFormat: 'dd/mm/yy',
    changeMonth: true,
    changeYear: true,
    viewMode: 'months'
});
$("#date_stop").datepicker({
    autoclose: true,
    todayHighlight: true,
    dateFormat: 'dd/mm/yy',
    changeMonth: true,
    changeYear: true,
    viewMode: 'months'
});
$( "#date_start" ).datepicker().datepicker("setDate", "1d");
$( "#date_stop" ).datepicker().datepicker("setDate", '2d');

Mine worked when I copied packages folder along with solution file and project folder. I just did not copy packages folder from previous place.

If you use MVC, you don't have this menu (no "Browse With..." menu)

Create first a normal ASP.NET web site.

In short - yes. They are worth every ounce of effort... to a point. Tests are, at the end of the day, still code, and much like typical code growth, your tests will eventually need to be refactored in order to be maintainable and sustainable. There's a tonne of GOTCHAS! when it comes to unit testing, but man oh man oh man, nothing, and I mean NOTHING empowers a developer to make changes more confidently than a rich set of unit tests.

I'm working on a project right now.... it's somewhat TDD, and we have the majority of our business rules encapuslated as tests... we have about 500 or so unit tests right now. This past iteration I had to revamp our datasource and how our desktop application interfaces with that datasource. Took me a couple days, the whole time I just kept running unit tests to see what I broke and fixed it. Make a change; Build and run your tests; fix what you broke. Wash, Rinse, Repeat as necessary. What would have traditionally taken days of QA and boat loads of stress was instead a short and enjoyable experience.

Prep up front, a little bit of extra effort, and it pays 10-fold later on when you have to start dicking around with core features/functionality.

I bought this book - it's a Bible of xUnit Testing knowledge - tis probably one of the most referenced books on my shelf, and I consult it daily: link text

system "sleep 0.1";

does the trick.

For objects array use map with indexOf:

var imageList = [_x000D_
   {value: 100},_x000D_
   {value: 200},_x000D_
   {value: 300},_x000D_
   {value: 400},_x000D_
   {value: 500}_x000D_
];_x000D_
_x000D_
var index = imageList.map(function (img) { return img.value; }).indexOf(200);_x000D_
_x000D_
console.log(index);

In modern browsers you can use findIndex:

var imageList = [_x000D_
   {value: 100},_x000D_
   {value: 200},_x000D_
   {value: 300},_x000D_
   {value: 400},_x000D_
   {value: 500}_x000D_
];_x000D_
_x000D_
var index = imageList.findIndex(img => img.value === 200);_x000D_
_x000D_
console.log(index);

mkdir C:\VTS 2> NUL

create a folder called VTS and output A subdirectory or file TEST already exists to NUL.

or

(C:&(mkdir "C:\VTS" 2> NUL))&

change the drive letter to C:, mkdir, output error to NUL and run the next command.

@keyframes slidein {
    0%   {margin-left:1500px;}

    animation-duration: .9s;
    display: block;
}

It depends what you're going for. I believe the closest thing JS has to print is:

document.write( produceMessage() );

However, it may be more prudent to place the value inside a span or a div of your choosing like:

document.getElementById("mySpanId").innerHTML = produceMessage();

To check for a timeout, I believe you check the value of ex.Number. If it is -2, then you have a timeout situation.

-2 is the error code for timeout, returned from DBNETLIB, the MDAC driver for SQL Server. This can be seen by downloading Reflector, and looking under System.Data.SqlClient.TdsEnums for TIMEOUT_EXPIRED.

Your code would read:

if (ex.Number == -2)
{
     //handle timeout
}

Code to demonstrate failure:

try
{
    SqlConnection sql = new SqlConnection(@"Network Library=DBMSSOCN;Data Source=YourServer,1433;Initial Catalog=YourDB;Integrated Security=SSPI;");
    sql.Open();

    SqlCommand cmd = sql.CreateCommand();
    cmd.CommandText = "DECLARE @i int WHILE EXISTS (SELECT 1 from sysobjects) BEGIN SELECT @i = 1 END";
    cmd.ExecuteNonQuery(); // This line will timeout.

    cmd.Dispose();
    sql.Close();
}
catch (SqlException ex)
{
    if (ex.Number == -2) {
        Console.WriteLine ("Timeout occurred");
    }
}

^\s*(\w+)\s*\(\s*(\d+)\D+(\d+)\D+\)\s*$

should work. After the match, backreference 1 will contain the month, backreference 2 will contain the first number and backreference 3 the second number.

Explanation:

^     # start of string
\s*   # optional whitespace
(\w+) # one or more alphanumeric characters, capture the match
\s*   # optional whitespace
\(    # a (
\s*   # optional whitespace
(\d+) # a number, capture the match
\D+   # one or more non-digits
(\d+) # a number, capture the match
\D+   # one or more non-digits
\)    # a )
\s*   # optional whitespace
$     # end of string

Use Assembly.GetTypes. For example:

Assembly mscorlib = typeof(string).Assembly;
foreach (Type type in mscorlib.GetTypes())
{
    Console.WriteLine(type.FullName);
}

In short, they are equivalent. Let's have a history view:

(1) at first, the function looks like this.

    class MySubClass(MySuperClass):
        def __init__(self):
            MySuperClass.__init__(self)

(2) to make code more abstract (and more portable). A common method to get Super-Class is invented like:

    super(<class>, <instance>)

And init function can be:

    class MySubClassBetter(MySuperClass):
        def __init__(self):
            super(MySubClassBetter, self).__init__()

However requiring an explicit passing of both the class and instance break the DRY (Don't Repeat Yourself) rule a bit.

(3) in V3. It is more smart,

    super()

is enough in most case. You can refer to http://www.python.org/dev/peps/pep-3135/

After trying a number of options and running into various issue with newer versions of Excel (2016) I came across this post from MS that worked like a charm. I enhanced it bit using some code from a post by danwagner.co

Split is slow, but not as slow as Scanner. StringTokenizer is faster than split. However, I found that I could obtain double the speed, by trading some flexibility, to get a speed-boost, which I did at JFastParser https://github.com/hughperkins/jfastparser

Testing on a string containing one million doubles:

Scanner: 10642 ms
Split: 715 ms
StringTokenizer: 544ms
JFastParser: 290ms

You could use the SQL%ROWCOUNT Oracle variable:

UPDATE table1
  SET field2 = value2, 
      field3 = value3 
WHERE field1 = value1; 

IF (SQL%ROWCOUNT = 0) THEN 

  INSERT INTO table (field1, field2, field3)
  VALUES (value1, value2, value3);

END IF; 

It would be easier just to determine if your primary key (i.e. field1) has a value and then perform an insert or update accordingly. That is, if you use said values as parameters for a stored procedure.

Primary keys are always indexed by default.

You can define a primary key in SQL Server 2012 by using SQL Server Management Studio or Transact-SQL. Creating a primary key automatically creates a corresponding unique, clustered or nonclustered index.

I was having some trouble with this so let me be very explicit so noobs like me can understand.

Lets say that we have a data file or something like that

Problem

The upstream server is timing out and I don't what is happening.

Where to Look first before increasing read or write timeout if your server is connecting to a database

Server is connecting to a database and that connection is working just fine and within sane response time, and its not the one causing this delay in server response time.

make sure that connection state is not causing a cascading failure on your upstream

Then you can move to look at the read and write timeout configurations of the server and proxy.

This syntax worked for me in MVC 3 with Razor:

@Html.ActionLink("Delete", "DeleteList", "List", new { ID = item.ID, ListID = item.id }, new {@class= "delete"})

I'd just like to add this to lfousts answer, from Ritchers book:

The C# language specification states, “As a matter of style, use of the keyword is favored over use of the complete system type name.” I disagree with the language specification; I prefer to use the FCL type names and completely avoid the primitive type names. In fact, I wish that compilers didn’t even offer the primitive type names and forced developers to use the FCL type names instead. Here are my reasons:

• I’ve seen a number of developers confused, not knowing whether to use string or String in their code. Because in C# string (a keyword) maps exactly to System.String (an FCL type), there is no difference and either can be used. Similarly, I’ve heard some developers say that int represents a 32-bit integer when the application is running on a 32-bit OS and that it represents a 64-bit integer when the application is running on a 64-bit OS. This statement is absolutely false: in C#, an int always maps to System.Int32, and therefore it represents a 32-bit integer regardless of the OS the code is running on. If programmers would use Int32 in their code, then this potential confusion is also eliminated.

• In C#, long maps to System.Int64, but in a different programming language, long could map to an Int16 or Int32. In fact, C++/CLI does treat long as an Int32. Someone reading source code in one language could easily misinterpret the code’s intention if he or she were used to programming in a different programming language. In fact, most languages won’t even treat long as a keyword and won’t compile code that uses it.

• The FCL has many methods that have type names as part of their method names. For example, the BinaryReader type offers methods such as ReadBoolean, ReadInt32, ReadSingle, and so on, and the System.Convert type offers methods such as ToBoolean, ToInt32, ToSingle, and so on. Although it’s legal to write the following code, the line with float feels very unnatural to me, and it’s not obvious that the line is correct:

  BinaryReader br = new BinaryReader(...);
  float val = br.ReadSingle(); // OK, but feels unnatural
  Single val = br.ReadSingle(); // OK and feels good
  

• Many programmers that use C# exclusively tend to forget that other programming languages can be used against the CLR, and because of this, C#-isms creep into the class library code. For example, Microsoft’s FCL is almost exclusively written in C# and developers on the FCL team have now introduced methods into the library such as Array’s GetLongLength, which returns an Int64 value that is a long in C# but not in other languages (like C++/CLI). Another example is System.Linq.Enumerable’s LongCount method.

I didn't get his opinion before I read the complete paragraph.

Perhaps the logic could be extracted into a helper? helpers are available to all classes and don't transfer control. You could check within it, perhaps for controller name, to see how it was called.

Returning the new object fits with the REST principle of "Uniform Interface - Manipulation of resources through representations." The complete object is the representation of the new state of the object that was created.

There is a really excellent reference for API design, here: Best Practices for Designing a Pragmatic RESTful API

It includes an answer to your question here: Updates & creation should return a resource representation

It says:

To prevent an API consumer from having to hit the API again for an updated representation, have the API return the updated (or created) representation as part of the response.

Seems nicely pragmatic to me and it fits in with that REST principle I mentioned above.

There should be no difference, but your tuple method is wrong, try:

a_list.append(tuple([3, 4]))

@thebjorn has given a good answer. But if you want more options, you can try OpenCV, SimpleCV.

using SimpleCV (not supported in python3.x):

from SimpleCV import Image, Camera

cam = Camera()
img = cam.getImage()
img.save("filename.jpg")

using OpenCV:

from cv2 import *
# initialize the camera
cam = VideoCapture(0)   # 0 -> index of camera
s, img = cam.read()
if s:    # frame captured without any errors
    namedWindow("cam-test",CV_WINDOW_AUTOSIZE)
    imshow("cam-test",img)
    waitKey(0)
    destroyWindow("cam-test")
    imwrite("filename.jpg",img) #save image

using pygame:

import pygame
import pygame.camera

pygame.camera.init()
pygame.camera.list_cameras() #Camera detected or not
cam = pygame.camera.Camera("/dev/video0",(640,480))
cam.start()
img = cam.get_image()
pygame.image.save(img,"filename.jpg")

Install OpenCV:

install python-opencv bindings, numpy

Install SimpleCV:

install python-opencv, pygame, numpy, scipy, simplecv

get latest version of SimpleCV

Install pygame:

The pickle protocol formats:

Protocol version 0 is the original “human-readable” protocol and is backwards compatible with earlier versions of Python.

Protocol version 1 is an old binary format which is also compatible with earlier versions of Python.

Protocol version 2 was introduced in Python 2.3. It provides much more efficient pickling of new-style classes. Refer to PEP 307 for information about improvements brought by protocol 2.

Protocol version 3 was added in Python 3.0. It has explicit support for bytes objects and cannot be unpickled by Python 2.x. This is the default protocol, and the recommended protocol when compatibility with other Python 3 versions is required.

Protocol version 4 was added in Python 3.4. It adds support for very large objects, pickling more kinds of objects, and some data format optimizations. Refer to PEP 3154 for information about improvements brought by protocol 4.

The getActionCommand() method returns an String associated with that Component set through the setActionCommand() , whereas the getSource() method returns an Object of the Object class specifying the source of the event.

If you're using MySQL you can run SHOW KEYS FROM table or SHOW INDEXES FROM table

You can use np.logaddexp (which implements the idea in @gg349's answer):

In [33]: d = np.array([[1089, 1093]])

In [34]: e = np.array([[1000, 4443]])

In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])

In [36]: log_res
Out[36]: -266.99999385580668

In [37]: res = exp(log_res)

In [38]: res
Out[38]: 1.1050349147204485e-116

Or you can use scipy.special.logsumexp:

In [52]: from scipy.special import logsumexp

In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))

In [54]: res
Out[54]: 1.1050349147204485e-116

even you can compile your c++ code by gcc Sounds funny ?? Yes it is. try it

$  gcc avishay.cpp -lstdc++

Replace String with your URL. and testImage is an outlet of ImageView

// Put Your Image URL
let url:NSURL = NSURL(string : "http://.jpg")!
// It Will turn Into Data
let imageData : NSData = NSData.init(contentsOf: url as URL)!
// Data Will Encode into Base64
let str64 = imageData.base64EncodedData(options: .lineLength64Characters)
// Now Base64 will Decode Here
let data: NSData = NSData(base64Encoded: str64 , options: .ignoreUnknownCharacters)!
// turn  Decoded String into Data
let dataImage = UIImage(data: data as Data)
// pass the data image to image View.:)
testImage.image = dataImage

Hope It Helps Thanks.

First create assets folder then create fonts folder in it.

Then you can set font from assets or directory like bellow :

public class FontSampler extends Activity {
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);

        TextView tv = (TextView) findViewById(R.id.custom);
        Typeface face = Typeface.createFromAsset(getAssets(), "fonts/HandmadeTypewriter.ttf");

        tv.setTypeface(face);

        File font = new File(Environment.getExternalStorageDirectory(), "MgOpenCosmeticaBold.ttf");

        if (font.exists()) {
            tv = (TextView) findViewById(R.id.file);
            face = Typeface.createFromFile(font);

            tv.setTypeface(face);
        } else {
            findViewById(R.id.filerow).setVisibility(View.GONE);
        }
    }
} 

I just tried the first answer from Brad Rem and came to this setting in the web.config under BasicHttpBinding:

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding bypassProxyOnLocal="False" useDefaultWebProxy="false" proxyAddress="http://127.0.0.1:8888" ...
        ...
      </basicHttpBinding>
    </bindings>
    ...
<system.serviceModel>

Hope this helps someone.

To keep the aspect ratio you have to use android:scaleType=fitCenter or fitStart etc. Using fitXY will not keep the original aspect ratio of the image!

Note this works only for images with a src attribute, not for the background image.

Update 2019

This is now IsEnabled

 takePicturebutton.IsEnabled = false; // true

The reason is because you are using the transform property twice. Due to CSS rules with the cascade, the last declaration wins if they have the same specificity. As both transform declarations are in the same rule set, this is the case.

What it is doing is this:

1. rotate the text 90 degrees. Ok.
2. translate 50% by 50%. Ok, this is same property as step one, so do this step and ignore step 1.

See http://jsfiddle.net/Lx76Y/ and open it in the debugger to see the first declaration overwritten

As the translate is overwriting the rotate, you have to combine them in the same declaration instead: http://jsfiddle.net/Lx76Y/1/

To do this you use a space separated list of transforms:

#rotatedtext {
    transform-origin: left;
    transform: translate(50%, 50%) rotate(90deg) ;
}

Remember that they are specified in a chain, so the translate is applied first, then the rotate after that.

This in an example that can be used for example to feed a database key, I sometimes use instead of using AUTOINCREMENT options.

import datetime 

dt = datetime.datetime.now()
seq = int(dt.strftime("%Y%m%d%H%M%S"))

Just write

@section Scripts{
    <script src="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/bundles/jqueryval")"></script>
}

Here is how it works for me with no Servlet use.

Let's say I am trying to access web.xml in project/WebContent/WEB-INF/web.xml

1. In project property Source-tab add source folder by pointing to the parent container for WEB-INF folder (in my case WebContent )

2. Now let's use class loader:

   InputStream inStream = class.getClass().getClassLoader().getResourceAsStream("Web-INF/web.xml")
   

I use Cygwin. I run into a lot of people that do not realize that if you put the Cygwin binaries on your PATH, you can use them from within the Windows Command shell. You do not have to run Cygwin's Bash.

You might also look into Windows Services for Unix available from Microsoft (but only on the Professional and above versions of Windows).

It turns out this is either a poorly documented, intentionally misleading, or undocumented interaction between the "controls" param and the "modestbranding" param. There is no way to remove YouTube's logo from an embedded YouTube video, at least while the video controls are exposed. All you get to do is choose how and when you want the logo to appear. Here are the details:

If controls = 1 and modestbranding = 1, then the YouTube logo is bigger, is on the video still image as a grayscale watermark in the lower right, and shows when the play controls are exposed as a big gray scale watermark in the lower right. example: <iframe width="560" height="315" src="https://www.youtube.com/embed/Z6ytvzNlmRo?rel=0&amp;controls=1&amp&amp;showinfo=0&amp;modestbranding=1" frameborder="0"></iframe>

If controls = 1 and modestbranding = 0 (our change here), then the YouTube logo is smaller, is not on the video still image as a grayscale watermark in the lower right, and shows only when the controls are exposed as a white icon in the lower right. example: <iframe width="560" height="315" src="https://www.youtube.com/embed/Z6ytvzNlmRo?rel=0&amp;controls=1&amp&amp;showinfo=0&amp;modestbranding=0" frameborder="0"></iframe>

If controls = 0, then the modestbranding param is ignored and the YouTube logo is bigger, is on the video still image as a grayscale watermark in the lower right, the watermark appears on hover of a playing video, and the watermark appears in the lower right of any paused video. example: <iframe width="560" height="315" src="https://www.youtube.com/embed/Z6ytvzNlmRo?rel=0&amp;controls=0&amp&amp;showinfo=0&amp;modestbranding=1" frameborder="0"></iframe>

I got same error in my application.I am loading many controls in single page.In button click event i am clearing the controls.clearing the controls doesnot release the controls from memory.So dispose the controls from memory. I just commented controls.clear() method and include few lines of code to dispose the controls. Something like this

for each ctl as control in controlcollection

ctl.dispose()

Based on @cudds's answer:

function s3size()
{
    for path in $*; do
        size=$(aws s3 ls "s3://$path" --recursive | grep -v -E "(Bucket: |Prefix: |LastWriteTime|^$|--)" | awk 'BEGIN {total=0}{total+=$3}END{printf "%.2fGb\n", (total/1024/1024/1024)}')
        echo "[s3://$path]=[$size]"
    done
}

...

$ s3size bucket-a bucket-b/dir
[s3://bucket-a]=[24.04Gb]
[s3://bucket-b/dir]=[26.69Gb]

Also, Cyberduck conveniently allows for calculation of size for a bucket or a folder.

if (!obj) {
    // object (not class!) doesn't exist yet
}
else ...

In my case, the solution was to make every directory in the directory path readable and accessible by mysql (chmod a+rx). The directory was still specified by its relative path in the command line.

chmod a+rx /tmp
chmod a+rx /tmp/migration
etc.

UPDATE TableName
 SET YourField = ''
WHERE YourField REGEXP 'YOUR REGEX'

And :

SELECT * from TableName
 WHERE YourField REGEXP 'YOUR REGEX'

I think you can still rely on CSS

ctx.measureText().height doesn’t exist.

Luckily, through CSS hack-ardry ( seeTypographic Metrics for more ways to fix older implementations of using CSS measurements), we can find the height of the text through measuring the offsetHeight of a with the same font-properties:

var d = document.createElement(”span”);
d.font = “20px arial”
d.textContent = “Hello world!”
var emHeight = d.offsetHeight;

from: http://www.html5rocks.com/en/tutorials/canvas/texteffects/

Actually, pretty much anywhere in typescript, passing a value to a function with a specified type will work as desired as long as the type being passed is compatible.

That being said, the following works...

 fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json())
      .then((res: Actor) => {
          // res is now an Actor
      });

I wanted to wrap all of my http calls in a reusable class - which means I needed some way for the client to process the response in its desired form. To support this, I accept a callback lambda as a parameter to my wrapper method. The lambda declaration accepts an any type as shown here...

callBack: (response: any) => void

But in use the caller can pass a lambda that specifies the desired return type. I modified my code from above like this...

fetch(`http://swapi.co/api/people/1/`)
  .then(res => res.json())
  .then(res => {
      if (callback) {
        callback(res);    // Client receives the response as desired type.  
      }
  });

So that a client can call it with a callback like...

(response: IApigeeResponse) => {
    // Process response as an IApigeeResponse
}

Here is what you are looking for:

String sDate = DateTime.Now.ToString();
DateTime datevalue = (Convert.ToDateTime(sDate.ToString()));

String dy = datevalue.Day.ToString();
String mn = datevalue.Month.ToString();
String yy = datevalue.Year.ToString();

OR

Alternatively, you can use split function to split string date into day, month and year here.

Hope, it will helps you... Cheers. !!

After some more research, it appears, for Mozilla/Firefox, that Array.sort() uses mergesort. See the code here.

Use Func<T> rather than Action<T>.

Action<T> acts like a void method with parameter of type T, while Func<T> works like a function with no parameters and which returns an object of type T.

If you wish to give parameters to your function, use Func<TParameter1, TParameter2, ..., TReturn>.

Dim f as Range

Set f=ActiveSheet.Cells.Find(...)

If Not f Is Nothing then
    msgbox "Row=" & f.Row & vbcrlf & "Column=" & f.Column
Else
    msgbox "value not found!"
End If

Have a look on: http://www.cplusplus.com/reference/random/normal_distribution/. It's the simplest way to produce normal distributions.

You can retrieve the format strings from the CultureInfo DateTimeFormat property, which is a DateTimeFormatInfo instance. This in turn has properties like ShortDatePattern and ShortTimePattern, containing the format strings:

CultureInfo us = new CultureInfo("en-US");
string shortUsDateFormatString = us.DateTimeFormat.ShortDatePattern;
string shortUsTimeFormatString = us.DateTimeFormat.ShortTimePattern;

CultureInfo uk = new CultureInfo("en-GB");
string shortUkDateFormatString = uk.DateTimeFormat.ShortDatePattern;
string shortUkTimeFormatString = uk.DateTimeFormat.ShortTimePattern;

If you simply want to format the date/time using the CultureInfo, pass it in as your IFormatter when converting the DateTime to a string, using the ToString method:

string us = myDate.ToString(new CultureInfo("en-US"));
string uk = myDate.ToString(new CultureInfo("en-GB"));

my 2cents would be to use json.MarshalIndent -- surprised this isn't suggested, as it is the most straightforward. for example:

func prettyPrint(i interface{}) string {
    s, _ := json.MarshalIndent(i, "", "\t")
    return string(s)
}

no external deps and results in nicely formatted output.

Since you're talking about polymorphism then yes, you can, we were doing that sort of stuff years before C++ came about.

Basically you use a struct to hold both the data and a list of function pointers to point to the relevant functions for that data.

So, in a communications class, you would have an open, read, write and close call which would be maintained as four function pointers in the structure, alongside the data for an object, something like:

typedef struct {
    int (*open)(void *self, char *fspec);
    int (*close)(void *self);
    int (*read)(void *self, void *buff, size_t max_sz, size_t *p_act_sz);
    int (*write)(void *self, void *buff, size_t max_sz, size_t *p_act_sz);
    // And data goes here.
} tCommClass;

tCommClass commRs232;
commRs232.open = &rs232Open;
: :
commRs232.write = &rs232Write;

tCommClass commTcp;
commTcp.open = &tcpOpen;
: :
commTcp.write = &tcpWrite;

Of course, those code segments above would actually be in a "constructor" such as rs232Init().

When you 'inherit' from that class, you just change the pointers to point to your own functions. Everyone that called those functions would do it through the function pointers, giving you your polymorphism:

int stat = (commTcp.open)(commTcp, "bigiron.box.com:5000");

Sort of like a manual vtable.

You could even have virtual classes by setting the pointers to NULL -the behaviour would be slightly different to C++ (a core dump at run-time rather than an error at compile time).

Here's a piece of sample code that demonstrates it. First the top-level class structure:

#include <stdio.h>

// The top-level class.

typedef struct sCommClass {
    int (*open)(struct sCommClass *self, char *fspec);
} tCommClass;

Then we have the functions for the TCP 'subclass':

// Function for the TCP 'class'.

static int tcpOpen (tCommClass *tcp, char *fspec) {
    printf ("Opening TCP: %s\n", fspec);
    return 0;
}
static int tcpInit (tCommClass *tcp) {
    tcp->open = &tcpOpen;
    return 0;
}

And the HTTP one as well:

// Function for the HTTP 'class'.

static int httpOpen (tCommClass *http, char *fspec) {
    printf ("Opening HTTP: %s\n", fspec);
    return 0;
}
static int httpInit (tCommClass *http) {
    http->open = &httpOpen;
    return 0;
}

And finally a test program to show it in action:

// Test program.

int main (void) {
    int status;
    tCommClass commTcp, commHttp;

    // Same 'base' class but initialised to different sub-classes.

    tcpInit (&commTcp);
    httpInit (&commHttp);

    // Called in exactly the same manner.

    status = (commTcp.open)(&commTcp, "bigiron.box.com:5000");
    status = (commHttp.open)(&commHttp, "http://www.microsoft.com");

    return 0;
}

This produces the output:

Opening TCP: bigiron.box.com:5000
Opening HTTP: http://www.microsoft.com

so you can see that the different functions are being called, depending on the sub-class.

Yes as long as it is public and you pass the correct args. See this link for more information. http://www.codestyle.org/java/faq-CommandLine.shtml#mainhost

To find duration or time interval with two different time zone

import org.joda.time.{DateTime, Period, PeriodType}

val s1 = "2019-06-13T05:50:00-07:00"
val s2 = "2019-10-09T11:30:00+09:00"    

val period = new Period(DateTime.parse(s1), DateTime.parse(s2), PeriodType dayTime())

period.getDays

git describe --abbrev=0 --tags

If you don't see latest tag, make sure of fetching origin before running that:

git remote update

In Sql Server:

insert into Table_Name(PersonName,PersonEmail) values(NULL,'[email protected]')

PersonName is varchar(50), NULL is not a string, because we are not passing with in single codes, so it treat as NULL.

Code Behind:

string name = (txtName.Text=="")? NULL : "'"+ txtName.Text +"'";
string email = txtEmail.Text;

insert into Table_Name(PersonName,PersonEmail) values(name,'"+email+"')

Try

sudo apt-get update
sudo apt-get install build-essential

(If I recall correctly the package name is without the extra s at the end).

You may want to look into to Simple Logging Facade for Java (SLF4J). It is a facade that wraps around Log4j that doesn't require an initial setup call like Log4j. It is also fairly easy to switch out Log4j for Slf4j as the API differences are minimal.

I can second the previous posters enthusiasm for the Gideros Lua game engine, whilst focusing currently on Mobile (iOS and Android - Windows phone 8 is in the works), desktop support for Mac, PC (possibly Linux) is also planned for the not too distant future.

Google for "Gideros Mobile"

Have you tried simply selecting by Id?

$("#header").focus();

Seeing as Ids should be unique, there's no need to have a more specific selector.

As shaishab roy says, in the cheat sheet you can find the answer.

But in his answer, the given response was :

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

For some reasons, it doesn't works on my side, so I tried instead :

{path: '/**', redirectTo: ['NotFound']}

and it works. Be careful and don't forget that you need to put it at the end, or else you will often have the 404 error page ;).

To solve this problem on Linux, you need to recompile your PHP with the --enable-mbstring flag.

To get the maximum value of a column across a set of rows:

SELECT MAX(column1) FROM table; -- expect one result

To get the maximum value of a set of columns, literals, or variables for each row:

SELECT GREATEST(column1, 1, 0, @val) FROM table; -- expect many results

Did you remember to die() after sending the header? The 404 header doesn't automatically stop processing, so it may appear not to have done anything if there is further processing happening.

It's not good to REDIRECT to your 404 page, but you can INCLUDE the content from it with no problem. That way, you have a page that properly sends a 404 status from the correct URL, but it also has your "what are you looking for?" page for the human reader.

Why don't you use TextWatcher ?

Since you have a number of EditText boxes to be validated, I think the following shall suit you :

1. Your activity implements android.text.TextWatcher interface
2. You add TextChanged listeners to you EditText boxes

txt1.addTextChangedListener(this);
txt2.addTextChangedListener(this);
txt3.addTextChangedListener(this);

3. Of the overridden methods, you could use the afterTextChanged(Editable s) method as follows

@Override
public void afterTextChanged(Editable s) {
    // validation code goes here
}

The Editable s doesn't really help to find which EditText box's text is being changed. But you could directly check the contents of the EditText boxes like

String txt1String = txt1.getText().toString();
// Validate txt1String

in the same method. I hope I'm clear and if I am, it helps! :)

EDIT: For a cleaner approach refer to Christopher Perry's answer below.

G                       Goto line [count], default last line, on the first
                        non-blank character linewise.  If 'startofline' not
                        set, keep the same column.

V35G achieves what you want

keytool comes with the Java SDK. You should find it in the directory that contains javac, etc.

If you change your cell reference to use R1C1 notation (Tools|Options, General tab), then you can use a simple notation and paste it into any cell.

Now your formula is simply:

=RC[-1]

If you want window handles for ALL of your application's Windows for some reason, you can use the Application.Windows property to get at all the Windows and then use WindowInteropHandler to get at their handles as you have already demonstrated.

Taken from: http://developer.android.com/guide/topics/ui/ui-events.html

// Create an anonymous implementation of OnClickListener
private OnClickListener mCorkyListener = new OnClickListener() {
    public void onClick(View v) {
      // do something when the button is clicked
    }
};

protected void onCreate(Bundle savedValues) {
    ...
    // Capture our button from layout
    Button button = (Button)findViewById(R.id.corky);
    // Register the onClick listener with the implementation above
    button.setOnClickListener(mCorkyListener);
    ...
}

In my opinion, alloca(), where available, should be used only in a constrained manner. Very much like the use of "goto", quite a large number of otherwise reasonable people have strong aversion not just to the use of, but also the existence of, alloca().

For embedded use, where the stack size is known and limits can be imposed via convention and analysis on the size of the allocation, and where the compiler cannot be upgraded to support C99+, use of alloca() is fine, and I've been known to use it.

When available, VLAs may have some advantages over alloca(): The compiler can generate stack limit checks that will catch out-of-bounds access when array style access is used (I don't know if any compilers do this, but it can be done), and analysis of the code can determine whether the array access expressions are properly bounded. Note that, in some programming environments, such as automotive, medical equipment, and avionics, this analysis has to be done even for fixed size arrays, both automatic (on the stack) and static allocation (global or local).

On architectures that store both data and return addresses/frame pointers on the stack (from what I know, that's all of them), any stack allocated variable can be dangerous because the address of the variable can be taken, and unchecked input values might permit all sorts of mischief.

Portability is less of a concern in the embedded space, however it is a good argument against use of alloca() outside of carefully controlled circumstances.

Outside of the embedded space, I've used alloca() mostly inside logging and formatting functions for efficiency, and in a non-recursive lexical scanner, where temporary structures (allocated using alloca() are created during tokenization and classification, then a persistent object (allocated via malloc()) is populated before the function returns. The use of alloca() for the smaller temporary structures greatly reduces fragmentation when the persistent object is allocated.

If your goal is to put vertical lines in a container to separate side-by-side child elements (column elements), you could consider styling the container like this:

.container > *:not(:first-child) {
  border-left: solid gray 2px;
}

This adds a left border to all child elements starting from the 2nd child. In other words, you get vertical borders between adjacent children.

• > is a child selector. It matches any child of the element(s) specified on the left.
• * is a universal selector. It matches an element of any type.
• :not(:first-child) means it's not the first child of its parent.

Browser support: > * :first-child and :not()

I think this is better than a simple .child-except-first {border-left: ...} rule, because it makes more sense to have the vertical lines come from the container's rules, not the different child elements' rules.

Whether this is better than using a makeshift vertical rule element (by styling a horizontal rule, etc.) will depend on your use case, but this is an alternative at least.

Not that I've done this, but you could get around the double indexer call and still keep your code clean by using a static / extension method.

Ie.

public static IsDBNull<T>(this object value, T default)
{
    return (value == DBNull.Value)
        ? default
        : (T)value;
}

public static IsDBNull<T>(this object value)
{
    return value.IsDBNull(default(T));
}

Then:

IDataRecord record; // Comes from somewhere

entity.StringProperty = record["StringProperty"].IsDBNull<string>(null);
entity.Int32Property = record["Int32Property"].IsDBNull<int>(50);

entity.NoDefaultString = record["NoDefaultString"].IsDBNull<string>();
entity.NoDefaultInt = record["NoDefaultInt"].IsDBNull<int>();

Also has the benefit of keeping the null checking logic in one place. Downside is, of course, that it's an extra method call.

Just a thought.

I too wanted to do something similar, this is what I found: (SDK 3.1.3)

I have a view controller A (itself owned by a Nav controller) which loads VC B on a button press:

In AViewController.m

BViewController *bController = [[BViewController alloc] initWithNibName:@"Bnib" bundle:nil];
[self.navigationController pushViewController:bController animated:YES];
[bController release];

Now VC B has its interface from Bnib, but when a button is pressed, I want to go to an 'edit mode' which has a separate UI from a different nib, but I don't want a new VC for the edit mode, I want the new nib to be associated with my existing B VC.

So, in BViewController.m (in button press method)

NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"EditMode" owner:self options:nil];
UIView *theEditView = [nibObjects objectAtIndex:0];
self.editView = theEditView;
[self.view addSubview:theEditView];

Then on another button press (to exit edit mode):

[editView removeFromSuperview];

and I'm back to my original Bnib.

This works fine, but note my EditMode.nib has only 1 top level obj in it, a UIView obj. It doesn't matter whether the File's Owner in this nib is set as BViewController or the default NSObject, BUT make sure the View Outlet in the File's Owner is NOT set to anything. If it is, then I get a exc_bad_access crash and xcode proceeds to load 6677 stack frames showing an internal UIView method repeatedly called... so looks like an infinite loop. (The View Outlet IS set in my original Bnib however)

Hope this helps.

There are a lot of insightful answers there already, but still, I would to direct to a slightly different situation: Instead of precondition, that should be put on top of a function indeed, think of a step-by-step initialization, where you have to check for each step to succeed and then continue with the next. In this case, you cannot check everything at the top.

I found my code really unreadable when writing an ASIO host application with Steinberg's ASIOSDK, as I followed the nesting paradigm. It went like eight levels deep, and I cannot see a design flaw there, as mentioned by Andrew Bullock above. Of course, I could have packed some inner code to another function, and then nested the remaining levels there to make it more readable, but this seems rather random to me.

By replacing nesting with guard clauses, I even discovered a misconception of mine regarding a portion of cleanup-code that should have occurred much earlier within the function instead of at the end. With nested branches, I would never have seen that, you could even say they led to my misconception.

So this might be another situation where inverted ifs can contribute to a clearer code.

user = driver.find_element_by_name("username")
password = driver.find_element_by_name("password")
user.clear()
user.send_keys("your_user_name")
password.clear()
password.send_keys("your_password")
driver.find_element_by_name("submit").click()

Note:

• we useuser.clear() in order to clear the input field.
• for locating submit button you can use any other method based on the page source code. for info see locating elements

If you plan to use the signed distance calculation snippet posted by phi (like I did) and your b might have value 0, you probably want to fix the code as described below:

import math

def distance(a, b):
    if (a == b):
        return 0
    elif (a < 0) and (b < 0) or (a > 0) and (b >= 0): # fix: b >= 0 to cover case b == 0
        if (a < b):
            return (abs(abs(a) - abs(b)))
        else:
            return -(abs(abs(a) - abs(b)))
    else:
        return math.copysign((abs(a) + abs(b)),b)

The original snippet does not work correctly regarding sign when a > 0 and b == 0.

Quick and dirty way is to do a global search for '\n'. You can filter it any way you like on file extensions etc.

Ctrl-Shift-F -> Text to find = '\n' -> Find.

Edit: And 'regular expression' has to be checked.

I had the same issue and my issue was the device not having the right date and time. Once I fixed that the certificate is being trusted.

Check out this metadata extractor. It is written in Java but has also been ported to C#. I have used the Java version to write a small utility to rename my jpeg files based on the date and model tags. Very easy to use.

EDIT metadata-extractor supports .NET too. It's a very fast and simple library for accessing metadata from images and videos.

It fully supports Exif, as well as IPTC, XMP and many other types of metadata from file types including JPEG, PNG, GIF, PNG, ICO, WebP, PSD, ...

var directories = ImageMetadataReader.ReadMetadata(imagePath);

// print out all metadata
foreach (var directory in directories)
foreach (var tag in directory.Tags)
    Console.WriteLine($"{directory.Name} - {tag.Name} = {tag.Description}");

// access the date time
var subIfdDirectory = directories.OfType<ExifSubIfdDirectory>().FirstOrDefault();
var dateTime = subIfdDirectory?.GetDateTime(ExifDirectoryBase.TagDateTime);

It's available via NuGet and the code's on GitHub.

I've been looking for better way of doing it recently. Associative array sounded like overkill for me. Look what I found:

suffix=bzz
declare prefix_$suffix=mystr

...and then...

varname=prefix_$suffix
echo ${!varname}

Run this:

SELECT CASE transaction_isolation_level 
WHEN 0 THEN 'Unspecified' 
WHEN 1 THEN 'ReadUncommitted' 
WHEN 2 THEN 'ReadCommitted' 
WHEN 3 THEN 'Repeatable' 
WHEN 4 THEN 'Serializable' 
WHEN 5 THEN 'Snapshot' END AS TRANSACTION_ISOLATION_LEVEL 
FROM sys.dm_exec_sessions 
where session_id = @@SPID

There is a way to terminate the process using Task Manager:

Note that this solution is for Windows only

1. Go to the Task Manager (or using the shortcut Ctrl + Shift + Esc)

2. On "Background Processes", find "Node.js" processes and terminate them (Right-click them and choose "End Task")

3. Now you should be able to start again

You can cast datetime to time

select CAST(GETDATE() as time)

If you want a hh:mm format

select cast(CAST(GETDATE() as time) as varchar(5))

Angular5 and 6:

angular 5 and 6 recommended way is to use @HostBindings and @HostListeners instead of the host property

remove host and add @HostListener

 @HostListener('ngModelChange', ['$event'])
  onModelChange(event) {
    this.onInputChange(event, false);
  }

  @HostListener('keydown.backspace', ['$event'])
  keydownBackspace(event) {
    this.onInputChange(event.target.value, true);
  }

One way you could do it is using a directive that injects NgControl and manipulates the value

(for details see inline comments)

@Directive({
  selector: '[ngModel][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)',
    '(keydown.backspace)': 'onInputChange($event.target.value, true)'
  }
})
export class PhoneMask {
  constructor(public model: NgControl) {}

  onInputChange(event, backspace) {
    // remove all mask characters (keep only numeric)
    var newVal = event.replace(/\D/g, '');
    // special handling of backspace necessary otherwise
    // deleting of non-numeric characters is not recognized
    // this laves room for improvement for example if you delete in the 
    // middle of the string
    if (backspace) {
      newVal = newVal.substring(0, newVal.length - 1);
    } 

    // don't show braces for empty value
    if (newVal.length == 0) {
      newVal = '';
    } 
    // don't show braces for empty groups at the end
    else if (newVal.length <= 3) {
      newVal = newVal.replace(/^(\d{0,3})/, '($1)');
    } else if (newVal.length <= 6) {
      newVal = newVal.replace(/^(\d{0,3})(\d{0,3})/, '($1) ($2)');
    } else {
      newVal = newVal.replace(/^(\d{0,3})(\d{0,3})(.*)/, '($1) ($2)-$3');
    }
    // set the new value
    this.model.valueAccessor.writeValue(newVal);       
  }
}

Try the following steps:

1. Make sure you have connectivity (you can browse) (This kind of error is usually due to connectivity with Internet)

2. Download Maven and unzip it

3. Create a JAVA_HOME System Variable

4. Create an M2_HOME System Variable

5. Add %JAVA_HOME%\bin;%M2_HOME%\bin; to your PATH variable

6. Open a command window cmd. Check: mvn -v

7. If you have a proxy, you will need to configure it

http://maven.apache.org/guides/mini/guide-proxies.html

8. Make sure you have .m2/repository (erase all the folders and files below)

9. If you are going to use Eclipse, You will need to create the settings.xml

By default, oracle date subtraction returns a result in # of days.

So just multiply by 24 to get # of hours, and again by 60 for # of minutes.

In .NET 4 you don't need the ToArray() call - string.Join is overloaded to accept IEnumerable<T> or just IEnumerable<string>.

There are potentially more efficient ways of doing it before .NET 4, but do you really need them? Is this actually a bottleneck in your code?

You could iterate over the list, work out the final size, allocate a StringBuilder of exactly the right size, then do the join yourself. That would avoid the extra array being built for little reason - but it wouldn't save much time and it would be a lot more code.

I faced this same issue on CentOS 7 years later

Steps:

FIRST, configure the php-fpm settings:

-> systemctl stop php-fpm.service

-> cd /etc/php-fpm.d

-> ls -hal (should see a www.conf file)

-> cp www.conf www.conf.backup (back file up just in case)

-> vi www.conf

-> :/listen = (to get to the line we need to change)

-> i (to enter VI's text insertion mode)

-> change from listen = 127.0.0.1:9000 TO listen = /var/run/php-fpm/php-fpm.sock

-> Esc then :/listen.owner (to find it) then i (to change)

-> UNCOMMENT the listen.owner = nobody AND listen.group = nobody lines

-> Hit Esc then type :/user = then i

-> change user = apache TO user = nginx

-> AND change group = apache TO group = nginx

-> Hit Esc then :wq (to save and quit)

-> systemctl start php-fpm.service (now you will have a php-fpm.sock file)

SECOND, you configure your server {} block in your /etc/nginx/nginx.conf file. Then run:systemctl restart nginx.service

FINALLY, create a new .php file in your /usr/share/nginx/html directory for your Nginx server to serve up via the internet browser as a test.

-> vi /usr/share/nginx/html/mytest.php

-> type o

-> <?php echo date("Y/m/d-l"); ?> (PHP page will print date and day in browser)

-> Hit Esc

-> type :wq (to save and quite VI editor)

-> open up a browser and go to: http://yourDomainOrIPAddress/mytest.php (you should see the date and day printed)

UIView siblings are stacked in the order in which they are added to their superview. The UIView hierarchy methods and properties are there to manage view order. In UIView.h:

@property(nonatomic,readonly) UIView *superview;
@property(nonatomic,readonly,copy) NSArray *subviews;

- (void)removeFromSuperview;
- (void)insertSubview:(UIView *)view atIndex:(NSInteger)index;
- (void)exchangeSubviewAtIndex:(NSInteger)index1 withSubviewAtIndex:(NSInteger)index2;

- (void)addSubview:(UIView *)view;
- (void)insertSubview:(UIView *)view belowSubview:(UIView *)siblingSubview;
- (void)insertSubview:(UIView *)view aboveSubview:(UIView *)siblingSubview;

- (void)bringSubviewToFront:(UIView *)view;
- (void)sendSubviewToBack:(UIView *)view;

The sibling views are ordered back to front in the subviews array. So the topmost view will be:

[parentView.subviews lastObject];

and bottom view will be:

[parentView.subviews objectAtIndex:0];

Like Kolin Krewinkel said, [parentView bringSubviewToFront:view] will bring the view to the top, but this is only the case if the views are all siblings in the hierarchy.

In my case I use chrono and c function localtime_r which is thread-safe (in opposition to std::localtime).

#include <iostream>
#include <chrono>
#include <ctime>
#include <time.h>
#include <iomanip>


int main() {
  std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
  std::time_t currentTime = std::chrono::system_clock::to_time_t(now);
  std::chrono::milliseconds now2 = std::chrono::duration_cast<std::chrono::milliseconds>(now.time_since_epoch());
  struct tm currentLocalTime;
  localtime_r(&currentTime, &currentLocalTime);
  char timeBuffer[80];
  std::size_t charCount { std::strftime( timeBuffer, 80,
                                         "%b %d %T",
                                          &currentLocalTime)
                         };

  if (charCount == 0) return -1;

  std::cout << timeBuffer << "." << std::setfill('0') << std::setw(3) << now2.count() % 1000 << std::endl;
  return 0;
}

For latest browser, like Chrome, you can use the File API as in this tutorial:

window.requestFileSystem  = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(window.PERSISTENT, 5*1024*1024 /*5MB*/, saveFile, errorHandler);

Try the following

typeField == typeof(string)
typeField == typeof(DateTime)

The typeof operator in C# will give you a Type object for the named type. Type instances are comparable with the == operator so this is a good method for comparing them.

Note: If I remember correctly, there are some cases where this breaks down when the types involved are COM interfaces which are embedded into assemblies (via NoPIA). Doesn't sound like this is the case here.

Previous answers are good, I'd just like to share a utility function I wrote to select Tensors from a graph:

def get_graph_op(graph, and_conds=None, op='and', or_conds=None):
    """Selects nodes' names in the graph if:
    - The name contains all items in and_conds
    - OR/AND depending on op
    - The name contains any item in or_conds

    Condition starting with a "!" are negated.
    Returns all ops if no optional arguments is given.

    Args:
        graph (tf.Graph): The graph containing sought tensors
        and_conds (list(str)), optional): Defaults to None.
            "and" conditions
        op (str, optional): Defaults to 'and'. 
            How to link the and_conds and or_conds:
            with an 'and' or an 'or'
        or_conds (list(str), optional): Defaults to None.
            "or conditions"

    Returns:
        list(str): list of relevant tensor names
    """
    assert op in {'and', 'or'}

    if and_conds is None:
        and_conds = ['']
    if or_conds is None:
        or_conds = ['']

    node_names = [n.name for n in graph.as_graph_def().node]

    ands = {
        n for n in node_names
        if all(
            cond in n if '!' not in cond
            else cond[1:] not in n
            for cond in and_conds
        )}

    ors = {
        n for n in node_names
        if any(
            cond in n if '!' not in cond
            else cond[1:] not in n
            for cond in or_conds
        )}

    if op == 'and':
        return [
            n for n in node_names
            if n in ands.intersection(ors)
        ]
    elif op == 'or':
        return [
            n for n in node_names
            if n in ands.union(ors)
        ]

So if you have a graph with ops:

['model/classifier/dense/kernel',
'model/classifier/dense/kernel/Assign',
'model/classifier/dense/kernel/read',
'model/classifier/dense/bias',
'model/classifier/dense/bias/Assign',
'model/classifier/dense/bias/read',
'model/classifier/dense/MatMul',
'model/classifier/dense/BiasAdd',
'model/classifier/ArgMax/dimension',
'model/classifier/ArgMax']

Then running

get_graph_op(tf.get_default_graph(), ['dense', '!kernel'], 'or', ['Assign'])

returns:

['model/classifier/dense/kernel/Assign',
'model/classifier/dense/bias',
'model/classifier/dense/bias/Assign',
'model/classifier/dense/bias/read',
'model/classifier/dense/MatMul',

I know for there's Fluid and Prism (there are others, that's the one I used to use) that let you load a website into what looks like a standalone app.

In Chrome, you can create desktop shortcuts for websites. (you do that from within Chrome, you can't/shouldn't package that with your app) Chrome Frame is different:

Google Chrome Frame is a plug-in designed for Internet Explorer based on the open-source Chromium project; it brings Google Chrome's open web technologies to Internet Explorer.

You'd need to have some sort of wrapper like that for your webapp, and then the rest is the web technologies you're used to. You can use HTML5 local storage to store data while the app is offline. I think you might even be able to work with SQLite.

I don't know how you would go about accessing OS specific features, though. What I described above has the same limitations as any "regular" website. Hopefully this gives you some sort of guidance on where to start.

This is my solution. I Hide and then confirm check

onclick="return ConfirmSubmit(this);" />

function ConfirmSubmit(sender)
    {
        sender.disabled = true;
        var displayValue = sender.style.
        sender.style.display = 'none'

        if (confirm('Seguro que desea entregar los paquetes?')) {
            sender.disabled = false
            return true;
        }

        sender.disabled = false;
        sender.style.display = displayValue;
        return false;
    }

To manually generate a Certificate, you need a Certificate Signing Request (CSR) file from your Mac. To create a CSR file, follow the instructions below to create one using Keychain Access.

Create a CSR file. In the Applications folder on your Mac, open the Utilities folder and launch Keychain Access.

Within the Keychain Access drop down menu, select Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority.

In the Certificate Information window, enter the following information: In the User Email Address field, enter your email address. In the Common Name field, create a name for your private key (e.g., John Doe Dev Key). The CA Email Address field should be left empty. In the "Request is" group, select the "Saved to disk" option. Click Continue within Keychain Access to complete the CSR generating process.

If you want to combine two files where one overlays the other (example: document A is a template and document B has the text you want to put on the template), this works:

after creating "doc", you want to write your template (templateFile) on top of that -

   PDDocument watermarkDoc = PDDocument.load(getServletContext()
                .getRealPath(templateFile));
   Overlay overlay = new Overlay();

   overlay.overlay(watermarkDoc, doc);

I have resolved this same issue by doing below steps:

1. File > Close Project

2. Import Project

3. Select you project via the system file popup

4. Check "Import project from external model" radio button and select Maven entry

5. And some Next buttons (select JDK, ...)

Then the project will be imported as Maven module.

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

This should do it for you ...

from pyspark.sql.types import FloatType
from pyspark.sql.functions import randn, rand, lit, coalesce, col
import pyspark.sql.functions as F

df_1 = sqlContext.range(0, 6)
df_2 = sqlContext.range(3, 10)
df_1 = df_1.select("id", lit("old").alias("source"))
df_2 = df_2.select("id")

df_1.show()
df_2.show()
df_3 = df_1.alias("df_1").join(df_2.alias("df_2"), df_1.id == df_2.id, "outer")\
  .select(\
    [coalesce(df_1.id, df_2.id).alias("id")] +\
    [col("df_1." + c) for c in df_1.columns if c != "id"])\
  .sort("id")
df_3.show()

List<String[]> addresses = new ArrayList<String[]>();
String[] addressesArr  = new String[3];

addressesArr[0] = "zero";
addressesArr[1] = "one";
addressesArr[2] = "two";

addresses.add(addressesArr);

In my case this problem happened when I imported a Maven project into Eclipse. To solve this, I added the following in pom.xml:

<properties>
   ...
   <maven.compiler.source>1.8</maven.compiler.source>
   <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Then in the context menu of the project, go to "Maven -> Update Project ...", and press OK.

That's it. Hope this helps.
