To show NumberPicker in AlertDialog use this code :

final AlertDialog.Builder d = new AlertDialog.Builder(context);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.number_picker_dialog, null);
d.setTitle("Title");
d.setMessage("Message");
d.setView(dialogView);
final NumberPicker numberPicker = (NumberPicker) dialogView.findViewById(R.id.dialog_number_picker);
numberPicker.setMaxValue(50);
numberPicker.setMinValue(1);
numberPicker.setWrapSelectorWheel(false);
numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
    @Override
    public void onValueChange(NumberPicker numberPicker, int i, int i1) {
        Log.d(TAG, "onValueChange: ");
    }
});
d.setPositiveButton("Done", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
        Log.d(TAG, "onClick: " + numberPicker.getValue());
    }
});
d.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
    }
});
AlertDialog alertDialog = d.create();
alertDialog.show();

If [John Smith] is in cell A1, then use this formula to do what you want:

=SUBSTITUTE(SUBSTITUTE(A1, "[", ""), "]", "")

The inner SUBSTITUTE replaces all instances of "[" with "" and returns a new string, then the other SUBSTITUTE replaces all instances of "]" with "" and returns the final result.

I was using CakePHP and I was seeing this error:

This page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500

I went to see the CakePHP Debug Level defined at app\config\core.php:

/**
 * CakePHP Debug Level:
 *
 * Production Mode:
 *  0: No error messages, errors, or warnings shown. Flash messages redirect.
 *
 * Development Mode:
 *  1: Errors and warnings shown, model caches refreshed, flash messages halted.
 *  2: As in 1, but also with full debug messages and SQL output.
 *  3: As in 2, but also with full controller dump.
 *
 * In production mode, flash messages redirect after a time interval.
 * In development mode, you need to click the flash message to continue.
 */
Configure::write('debug', 0);

I chanted the value from 0 to 1:

Configure::write('debug', 1);

After this change, when trying to reload the page again, I saw the corresponding error:

Fatal error: Uncaught Exception: Facebook needs the CURL PHP extension.

Conclusion: The solution in my case to see the errors was to change the CakePHP Debug Level from 0 to 1 in order to show errors and warnings.

How to resize root partition online :  

1)  [root@oel7 ~]# df -h  
Filesystem                         Size  Used Avail Use% Mounted on  
/dev/mapper/root_vg-root           5.0G  4.5G  548M  90% /

2)   

PV /dev/sda2   VG root_vg     lvm2 [6.00 GiB / 0    free]

as here it shows that there is no space left on root_vg volume group, so first i need to extend VG 

3)  
[root@oel7 ~]# vgextend root_vg /dev/sdb5  

  Volume group "root_vg" successfully extended

4)  

[root@oel7 ~]# pvscan  
    PV /dev/sda2   VG root_vg     lvm2 [6.00 GiB / 0    free]  
    PV /dev/sdb5   VG root_vg     lvm2 [2.00 GiB / 2.00 GiB free]

5)  Now extend the logical volume   

[root@oel7 ~]# lvextend -L +1G /dev/root_vg/root  

  Size of logical volume root_vg/root changed from 5.00 GiB (1280 extents) to 6.00 GiB (1536 extents).
  Logical volume root successfully resized  

3)  [root@oel7 ~]# resize2fs /dev/root_vg/root  

resize2fs 1.42.9 (28-Dec-2013)  
resize2fs: Bad magic number in super-block while trying to open /dev/root_vg  /root  
Couldn't find valid filesystem superblock.  

as root partition is not a ext* partiton so , you resize2fs will not work for you.  

4)  to check the filesystem type of a partition 
[root@oel7 ~]# df -Th  
Filesystem                        Type      Size  Used Avail Use% Mounted on  
/dev/mapper/root_vg-root          xfs       6.0G  4.5G  1.6G  75% /  
devtmpfs                          devtmpfs  481M     0  481M   0% /dev  
tmpfs                             tmpfs     491M   80K  491M   1% /dev/shm  
tmpfs                             tmpfs     491M  7.1M  484M   2% /run  
tmpfs                             tmpfs     491M     0  491M   0% /sys/fs  /cgroup
/dev/mapper/data_vg-home          xfs       3.5G  2.9G  620M  83% /home  
/dev/sda1                         xfs       497M  132M  365M  27% /boot  
/dev/mapper/data_vg01-data_lv001  ext3      4.0G  2.4G  1.5G  62% /sybase  
/dev/mapper/data_vg02-backup_lv01 ext3      4.0G  806M  3.0G  22% /backup  

above command shows that root is an xfs filesystem , so we are sure that we need to use xfs_growfs command to resize the partition.

6)  [root@oel7 ~]# xfs_growfs /dev/root_vg/root

If you want your result concatenated, as you show in your question, you could try something like:

>>> reduce(lambda x, y: str(x)+str(y), map(ord,"hello world"))
'10410110810811132119111114108100'

$('#selector').delay(5000).fadeOut('slow');

Java script plays on browser where java code is server side thing so you can't simply do this.

What you can do is submit the calculated variable from javascript to server by form-submission, or using URL parameter or using AJAX calls and then you can make it available on server

HTML

<input type="hidden" id="hiddenField"/>

make sure this fields lays under <form>

Javascript

document.getElementById("hiddenField").value=yourCalculatedVariable;

on server you would get this as a part of request

The endroid/QrCode library is easy to use, well maintained, and can be installed using composer. There is also a bundle to use directly with Symfony.

Installing :

$ composer require endroid/qrcode

Usage :

<?php

use Endroid\QrCode\QrCode;

$qrCode = new QrCode();
$qrCode
    ->setText('Life is too short to be generating QR codes')
    ->setSize(300)
    ->setPadding(10)
    ->setErrorCorrection('high')
    ->setForegroundColor(array('r' => 0, 'g' => 0, 'b' => 0, 'a' => 0))
    ->setBackgroundColor(array('r' => 255, 'g' => 255, 'b' => 255, 'a' => 0))
    ->setLabel('Scan the code')
    ->setLabelFontSize(16)
    ->setImageType(QrCode::IMAGE_TYPE_PNG)
;

// now we can directly output the qrcode
header('Content-Type: '.$qrCode->getContentType());
$qrCode->render();

// or create a response object
$response = new Response($qrCode->get(), 200, array('Content-Type' => $qrCode->getContentType()));

In my case, I had to deactivate AdBlock and it worked fine.

CASE
  WHEN ebv.db_no = 22978 OR 
       ebv.db_no = 23218 OR

This has changed in iOS 8. See the following tech note: https://developer.apple.com/library/ios/technotes/tn2406/_index.html

The Apple sanctioned way (from the link above) is as follows:

// Returns the URL to the application's Documents directory.
- (NSURL *)applicationDocumentsDirectory
{
    return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
}

You can replace hash with null

var urlWithoutHash = document.location.href.replace(location.hash , "" );

Don't do unless you absolutely need to and your code intent requires shifting rather than multiplication/division.

In typical day - you could potentialy save few machine cycles (or loose, since compiler knows better what to optimize), but the cost doesn't worth it - you spend time on minor details rather than actual job, maintaining the code becomes harder and your co-workers will curse you.

You might need to do it for high-load computations, where each saved cycle means minutes of runtime. But, you should optimize one place at a time and do performance tests each time to see if you really made it faster or broke compilers logic.

If you want to center map onto a marker and you have the cordinate, something like click on a list item and the map should center on that coordinate then the following code will work:

In HTML:

<ul class="locationList" ng-repeat="LocationDetail in coordinateArray| orderBy:'LocationName'">
   <li>
      <div ng-click="focusMarker(LocationDetail)">
          <strong><div ng-bind="locationDetail.LocationName"></div></strong>
          <div ng-bind="locationDetail.AddressLine"></div>
          <div ng-bind="locationDetail.State"></div>
          <div ng-bind="locationDetail.City"></div>
      <div>
   </li>
</ul>

In Controller:

$scope.focusMarker = function (coords) {
    map.setCenter(new google.maps.LatLng(coords.Latitude, coords.Longitude));
    map.setZoom(14);
}

Location Object:

{
    "Name": "Taj Mahal",
    "AddressLine": "Tajganj",
    "City": "Agra",
    "State": "Uttar Pradesh",
    "PhoneNumber": "1234 12344",
    "Latitude": "27.173891",
    "Longitude": "78.042068"
}

I did encounter the same problem while trying to read data from a Firebird Database. After many hours of searching, I found out that the problem was caused by an error I made in the query. Fixing it made it work perfectly. It had nothing to do with the version of the Framework

Test Data

DECLARE @Table1 TABLE(ID INT, Value INT)
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400)

Query

SELECT  ID
       ,STUFF((SELECT ', ' + CAST(Value AS VARCHAR(10)) [text()]
         FROM @Table1 
         WHERE ID = t.ID
         FOR XML PATH(''), TYPE)
        .value('.','NVARCHAR(MAX)'),1,2,' ') List_Output
FROM @Table1 t
GROUP BY ID

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

SQL Server 2017 and Later Versions

If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:

DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);


SELECT ID , STRING_AGG([Value], ', ') AS List_Output
FROM @Table1
GROUP BY ID;

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

If you need to create multiple columns at once:

1. Create the dataframe:

   import pandas as pd
   df = pd.DataFrame({"A": [10,20,30], "B": [20, 30, 10]})
   

2. Create the function:

   def fab(row):                                                  
       return row['A'] * row['B'], row['A'] + row['B']
   

3. Assign the new columns:

   df['newcolumn'], df['newcolumn2'] = zip(*df.apply(fab, axis=1))
   

use utf8; does not enable Unicode output - it enables you to type Unicode in your program. Add this to the program, before your print() statement:

binmode(STDOUT, ":utf8");

See if that helps. That should make STDOUT output in UTF-8 instead of ordinary ASCII.

The list.append function does not return any value(but None), it just adds the value to the list you are using to call that method.

In the first loop round you will assign None (because the no-return of append) to a, then in the second round it will try to call a.append, as a is None it will raise the Exception you are seeing

You just need to change it to:

a=[]
for i in range(5):    
    a.append(i)
print(a)
# [0, 1, 2, 3, 4]

list.append is what is called a mutating or destructive method, i.e. it will destroy or mutate the previous object into a new one(or a new state).

If you would like to create a new list based in one list without destroying or mutating it you can do something like this:

a=['a', 'b', 'c']
result = a + ['d']

print result
# ['a', 'b', 'c', 'd']

print a
# ['a', 'b', 'c']

As a corollary only, you can mimic the append method by doing the following:

a=['a', 'b', 'c']
a = a + ['d']

print a
# ['a', 'b', 'c', 'd']

If you use Object Relational Mapping tools or will in the future I suggest Singular.

Some tools like LLBLGen can automatically correct plural names like Users to User without changing the table name itself. Why does this matter? Because when it's mapped you want it to look like User.Name instead of Users.Name or worse from some of my old databases tables naming tblUsers.strName which is just confusing in code.

My new rule of thumb is to judge how it will look once it's been converted into an object.

one table I've found that does not fit the new naming I use is UsersInRoles. But there will always be those few exceptions and even in this case it looks fine as UsersInRoles.Username.

It's important to note that the order of parameters is actually important to spring. The BindingResult needs to come right after the Form that is being validated. Likewise, the [optional] Model parameter needs to come after the BindingResult. Example:

Valid:

@RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  final BindingResult bindingResult,
                                  @RequestParam("pk") final long pk,
                                  final Model model) {
}

Not Valid:

RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  @RequestParam("pk") final long pk,
                                  final BindingResult bindingResult,
                                  final Model model) {
}

You are probably seeking:

ActiveRecord::Base.connection.tables

and

ActiveRecord::Base.connection.columns('projects').map(&:name)

You should probably wrap them in shorter syntax inside your .irbrc.

Here's the simplest solution (Jibwa made it seem complicated in another answer), without having to generate indices yourself - just using the ShuffleSplit object to generate 1 split.

import numpy as np 
from sklearn.model_selection import ShuffleSplit # or StratifiedShuffleSplit
sss = ShuffleSplit(n_splits=1, test_size=0.1)

data_size = 100
X = np.reshape(np.random.rand(data_size*2),(data_size,2))
y = np.random.randint(2, size=data_size)

sss.get_n_splits(X, y)
train_index, test_index = next(sss.split(X, y)) 

X_train, X_test = X[train_index], X[test_index] 
y_train, y_test = y[train_index], y[test_index]

Or if you want a simple one-liner:

Person person = JAXB.unmarshal(new StringReader("<?xml ..."), Person.class);

1: Add the following line into the AssemblyInfo class

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

2: Make sure you don't use .Net Framework 4 Client Profile as Target Framework (I think this is OK on your side because otherwise it even wouldn't compile)

3: Make sure you log very early in your program. Otherwise, in some scenarios, it will not be initialized properly (read more on log4net FAQ).

So log something during application startup in the Global.asax

public class Global : System.Web.HttpApplication
{
    private static readonly log4net.ILog Log = log4net.LogManager.GetLogger(typeof(Global));
    protected void Application_Start(object sender, EventArgs e)
    {
        Log.Info("Startup application.");
    }
}

4: Make sure you have permission to create files and folders on the given path (if the folder itself also doesn't exist)

5: The rest of your given information looks ok

You need to use regular expressions in your custom validator. For example, here's the code that allows only 9 digits in the input fields:

function ssnValidator(control: FormControl): {[key: string]: any} {
  const value: string = control.value || '';
  const valid = value.match(/^\d{9}$/);
  return valid ? null : {ssn: true};
}

Take a look at a sample app here:

https://github.com/Farata/angular2typescript/tree/master/Angular4/form-samples/src/app/reactive-validator

I had same problem in VB.NET 2013 with Office 2007, and this solved it:

VS 2013 VB.NET Project > Props > Refs > Microsoft Word 12.0 Object Lib > Embed Interop Types: change True to False

In my case the answer is pretty simple. Please check carefully the hardcoded url port: it is 8080. For some reason the value has changed to: for example 3030.

Just refresh the port in your ajax url string to the appropriate one.

conn = new WebSocket('ws://localhost:3030'); //should solve the issue

As soon as you have run npm init and you start installing npm packages it'll create the node_moduals folder after that first install

e.g

npm init

(Asks you to set up your package.json file)

npm install <package name here> --save-dev

installs package & creates the node modules directory

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is) 

Full source code RoadProvider.java

BlackBerry

class MapPathScreen extends MainScreen {
    MapControl map;
    Road mRoad = new Road();
    public MapPathScreen() {
        double fromLat = 49.85, fromLon = 24.016667;
        double toLat = 50.45, toLon = 30.523333;
        String url = RoadProvider.getUrl(fromLat, fromLon, toLat, toLon);
        InputStream is = getConnection(url);
        mRoad = RoadProvider.getRoute(is);
        map = new MapControl();
        add(new LabelField(mRoad.mName));
        add(new LabelField(mRoad.mDescription));
        add(map);
    }
    protected void onUiEngineAttached(boolean attached) {
        super.onUiEngineAttached(attached);
        if (attached) {
            map.drawPath(mRoad);
        }
    }
    private InputStream getConnection(String url) {

serialize() effectively turns the form values into a valid querystring, as such you can simply append to the string:

$.ajax({
    type : 'POST',
    url : 'url',
    data : $('#form').serialize() + "&par1=1&par2=2&par3=232"
}

Try this:

Get-ChildItem -Path V:\Myfolder -Filter CopyForbuild.bat -Recurse | Where-Object { $_.Attributes -ne "Directory"}

Since you are learning Git, know that this has little to do with git but with the text editor configured for use. In vim, you can press i to start entering text and save by pressing esc and :wq and enter, this will commit with the message you typed. In your current state, to just come out without committing, you can do :q instead of the :wq as mentioned above.

Alternatively, you can just do git commit -m '<message>' instead of having git open the editor to type the message.

Note that you can also change the editor and use something you are comfortable with ( like notepad) - How can I set up an editor to work with Git on Windows?

I think currently your api's actually responding the way it should. The first 100 records on the page in the overall order of objects you are maintaining. Your explanation tells that you are using some kind of ordering ids to define the order of your objects for pagination.

Now, in case you want that page 2 should always start from 101 and end at 200, then you must make the number of entries on the page as variable, since they are subject to deletion.

You should do something like the below pseudocode:

page_max = 100
def get_page_results(page_no) :

    start = (page_no - 1) * page_max + 1
    end = page_no * page_max

    return fetch_results_by_id_between(start, end)

The Easy Way™

It turns out that this is such a common and useful practice that the overlords of Git made it really easy, but you have to have a newer version of Git (>= 1.7.11 May 2012). See the appendix for how to install the latest Git. Also, there's a real-world example in the walkthrough below.

0. Prepare the old repo

    cd <big-repo>
    git subtree split -P <name-of-folder> -b <name-of-new-branch>
   

Note: <name-of-folder> must NOT contain leading or trailing characters. For instance, the folder named subproject MUST be passed as subproject, NOT ./subproject/

Note for Windows users: When your folder depth is > 1, <name-of-folder> must have *nix style folder separator (/). For instance, the folder named path1\path2\subproject MUST be passed as path1/path2/subproject

1. Create the new repo

    mkdir ~/<new-repo> && cd ~/<new-repo>
    git init
    git pull </path/to/big-repo> <name-of-new-branch>
   

2. Link the new repo to GitHub or wherever

    git remote add origin <[email protected]:user/new-repo.git>
    git push -u origin master
   

3. Cleanup inside <big-repo>, if desired

    git rm -rf <name-of-folder>
   

Note: This leaves all the historical references in the repository. See the Appendix below if you're actually concerned about having committed a password or you need to decreasing the file size of your .git folder.

Walkthrough

These are the same steps as above, but following my exact steps for my repository instead of using <meta-named-things>.

Here's a project I have for implementing JavaScript browser modules in node:

tree ~/node-browser-compat

node-browser-compat
+-- ArrayBuffer
+-- Audio
+-- Blob
+-- FormData
+-- atob
+-- btoa
+-- location
+-- navigator

I want to split out a single folder, btoa, into a separate Git repository

cd ~/node-browser-compat/
git subtree split -P btoa -b btoa-only

I now have a new branch, btoa-only, that only has commits for btoa and I want to create a new repository.

mkdir ~/btoa/ && cd ~/btoa/
git init
git pull ~/node-browser-compat btoa-only

Next, I create a new repo on GitHub or Bitbucket, or whatever and add it as the origin

git remote add origin [email protected]:node-browser-compat/btoa.git
git push -u origin master

Happy day!

Note: If you created a repo with a README.md, .gitignore and LICENSE, you will need to pull first:

git pull origin master
git push origin master

Lastly, I'll want to remove the folder from the bigger repo

git rm -rf btoa

Appendix

Latest Git on macOS

To get the latest version of Git using Homebrew:

brew install git

Latest Git on Ubuntu

sudo apt-get update
sudo apt-get install git
git --version

If that doesn't work (you have a very old version of Ubuntu), try

sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git

If that still doesn't work, try

sudo chmod +x /usr/share/doc/git/contrib/subtree/git-subtree.sh
sudo ln -s \
/usr/share/doc/git/contrib/subtree/git-subtree.sh \
/usr/lib/git-core/git-subtree

Clearing your history

By default removing files from Git doesn't actually remove them, it just commits that they aren't there anymore. If you want to actually remove the historical references (i.e. you committed a password), you need to do this:

git filter-branch --prune-empty --tree-filter 'rm -rf <name-of-folder>' HEAD

After that, you can check that your file or folder no longer shows up in the Git history at all

git log -- <name-of-folder> # should show nothing

However, you can't "push" deletes to GitHub and the like. If you try, you'll get an error and you'll have to git pull before you can git push - and then you're back to having everything in your history.

So if you want to delete history from the "origin" - meaning to delete it from GitHub, Bitbucket, etc - you'll need to delete the repo and re-push a pruned copy of the repo. But wait - there's more! - if you're really concerned about getting rid of a password or something like that you'll need to prune the backup (see below).

Making .git smaller

The aforementioned delete history command still leaves behind a bunch of backup files - because Git is all too kind in helping you to not ruin your repo by accident. It will eventually delete orphaned files over the days and months, but it leaves them there for a while in case you realize that you accidentally deleted something you didn't want to.

So if you really want to empty the trash to reduce the clone size of a repo immediately you have to do all of this really weird stuff:

rm -rf .git/refs/original/ && \
git reflog expire --all && \
git gc --aggressive --prune=now

git reflog expire --all --expire-unreachable=0
git repack -A -d
git prune

That said, I'd recommend not performing these steps unless you know that you need to - just in case you did prune the wrong subdirectory, y'know? The backup files shouldn't get cloned when you push the repo, they'll just be in your local copy.

Assuming SQL Server (based on your previous questions):

ALTER TABLE Merchant_Pending_Functions ALTER COLUMN NumberOfLocations INT NULL

Replace INT with your actual datatype.

Just to add my results, also using Matplotlib.

.eps made all my text bold and removed transparency. .svg gave me high-resolution pictures that actually looked like my graph.

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
# Do the plot code
fig.savefig('myimage.svg', format='svg', dpi=1200)

I used 1200 dpi because a lot of scientific journals require images in 1200 / 600 / 300 dpi, depending on what the image is of. Convert to desired dpi and format in GIMP or Inkscape.

Obviously the dpi doesn't matter since .svg are vector graphics and have "infinite resolution".

You may want to take a look at those pages : http://developer.android.com/reference/android/os/Build.html and http://developer.android.com/reference/java/lang/System.html (the getProperty() method might do the job).

For instance :

System.getProperty("os.version"); // OS version
android.os.Build.VERSION.SDK      // API Level
android.os.Build.DEVICE           // Device
android.os.Build.MODEL            // Model 
android.os.Build.PRODUCT          // Product

Etc...

I personally prefer the simpler syntax of the ~ operator.

round(float("123.789"))

will give you an integer value, but a float type. With Python's duck typing, however, the actual type is usually not very relevant. This will also round the value, which you might not want. Replace 'round' with 'int' and you'll have it just truncated and an actual int. Like this:

int(float("123.789"))

But, again, actual 'type' is usually not that important.

I was curious about which method would be faster:

1. Using Distinct with a custom IEqualityComparer or
2. Using the GroupBy method described by Cuong Le.

I found that depending on the size of the input data and the number of groups, the Distinct method can be a lot more performant. (as the number of groups tends towards the number of elements in the list, distinct runs faster).

Code runs in LinqPad!

    void Main()
    {
        List<C> cs = new List<C>();
        foreach(var i in Enumerable.Range(0,Int16.MaxValue*1000))
        {
            int modValue = Int16.MaxValue; //vary this value to see how the size of groups changes performance characteristics. Try 1, 5, 10, and very large numbers
            int j = i%modValue; 
            cs.Add(new C{I = i, J = j});
        }
        cs.Count ().Dump("Size of input array");

        TestGrouping(cs);
        TestDistinct(cs);
    }

    public void TestGrouping(List<C> cs)
    {
        Stopwatch sw = Stopwatch.StartNew();
        sw.Restart();
        var groupedCount  = cs.GroupBy (o => o.J).Select(s => s.First()).Count();
        groupedCount.Dump("num groups");
        sw.ElapsedMilliseconds.Dump("elapsed time for using grouping");
    }

    public void TestDistinct(List<C> cs)
    {
        Stopwatch sw = Stopwatch.StartNew();
        var distinctCount = cs.Distinct(new CComparerOnJ()).Count ();
        distinctCount.Dump("num distinct");
        sw.ElapsedMilliseconds.Dump("elapsed time for using distinct");
    }

    public class C
    {
        public int I {get; set;}
        public int J {get; set;}
    }

    public class CComparerOnJ : IEqualityComparer<C>
    {
        public bool Equals(C x, C y)
        {
            return x.J.Equals(y.J);
        }

        public int GetHashCode(C obj)
        {
            return obj.J.GetHashCode();
        }
    }

The X-Frame-Options HTTP response header can be used to indicate whether or not a browser should be allowed to render a page in a <frame>, <iframe> or <object>. Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites.

For More Information: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options

I have an alternate solution for this problem, which I am going to demonstrate by using PHP:

iframe.php:

<iframe src="target_url.php" width="925" height="2400" frameborder="0" ></iframe>

target_url.php:

<?php 
  echo file_get_contents("http://www.example.com");
?>

My test string for the following:

testing='12345,abc,123,54321,ab15234,123456,52341';

If I understand your question, you'd want ["12345", "54321", "15234", "52341"].

If JS engines supported regexp lookbehinds, you could do:

testing.match(/(?<!\d)\d{5}(?!\d)/g)

Since it doesn't currently, you could:

testing.match(/(?:^|\D)(\d{5})(?!\d)/g)

and remove the leading non-digit from appropriate results, or:

pentadigit=/(?:^|\D)(\d{5})(?!\d)/g;
result = [];
while (( match = pentadigit.exec(testing) )) {
    result.push(match[1]);
}

Note that for IE, it seems you need to use a RegExp stored in a variable rather than a literal regexp in the while loop, otherwise you'll get an infinite loop.

You must create a new date object and set it as minDate when you initialize the datepickers

<label for="from">From</label> <input type="text" id="from" name="from"/> <label for="to">to</label> <input type="text" id="to" name="to"/>

var dateToday = new Date();
var dates = $("#from, #to").datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 3,
    minDate: dateToday,
    onSelect: function(selectedDate) {
        var option = this.id == "from" ? "minDate" : "maxDate",
            instance = $(this).data("datepicker"),
            date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
        dates.not(this).datepicker("option", option, date);
    }
});

Edit - from your comment now it works as expected http://jsfiddle.net/nicolapeluchetti/dAyzq/1/

According to the documentation you need to specify the key store:

Protocol authhttps = new Protocol("https",  
      new AuthSSLProtocolSocketFactory(
          new URL("file:my.keystore"), "mypassword",
          new URL("file:my.truststore"), "mypassword"), 443); 

 HttpClient client = new HttpClient();
 client.getHostConfiguration().setHost("localhost", 443, authhttps);

It is really very disappointing that you can't do it with styles (<item name="android:textAllCaps">true</item>) or on each XML layout file with the textAllCaps attribute, and the only way to do it is actually using theString.toUpperCase() on each of the strings when you do a textViewXXX.setText(theString).

In my case, I did not wanted to have theString.toUpperCase() everywhere in my code but to have a centralized place to do it because I had some Activities and lists items layouts with TextViews that where supposed to be capitalized all the time (a title) and other who did not... so... some people may think is an overkill, but I created my own CapitalizedTextView class extending android.widget.TextView and overrode the setText method capitalizing the text on the fly.

At least, if the design changes or I need to remove the capitalized text in future versions, I just need to change to normal TextView in the layout files.

Now, take in consideration that I did this because the App's Designer actually wanted this text (the titles) in CAPS all over the App no matter the original content capitalization, and also I had other normal TextViews where the capitalization came with the the actual content.

This is the class:

package com.realactionsoft.android.widget;

import android.content.Context; 
import android.util.AttributeSet; 
import android.view.ViewTreeObserver; 
import android.widget.TextView;


public class CapitalizedTextView extends TextView implements ViewTreeObserver.OnPreDrawListener {

    public CapitalizedTextView(Context context) {
        super(context);
    }

    public CapitalizedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CapitalizedTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        super.setText(text.toString().toUpperCase(), type);
    }

}

And whenever you need to use it, just declare it with all the package in the XML layout:

<com.realactionsoft.android.widget.CapitalizedTextView 
        android:id="@+id/text_view_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Some will argue that the correct way to style text on a TextView is to use a SpannableString, but I think that would be even a greater overkill, not to mention more resource-consuming because you'll be instantiating another class than TextView.

function DeletePersonel(id) {

    var data = new FormData();
    data.append("__RequestVerificationToken", "@HtmlHelper.GetAntiForgeryToken()");

    $.ajax({
        type: 'POST',
        url: '/Personel/Delete/' + id,
        data: data,
        cache: false,
        processData: false,
        contentType: false,
        success: function (result) {
        }
    });
}

public static class HtmlHelper {
    public static string GetAntiForgeryToken() {
        System.Text.RegularExpressions.Match value = 
                System.Text.RegularExpressions.Regex.Match(System.Web.Helpers.AntiForgery.GetHtml().ToString(), 
                        "(?:value=\")(.*)(?:\")");
        if (value.Success) {
            return value.Groups[1].Value;
        }
        return "";
    }
}

The compiler will start doing very clever things with optimisations turned on. The debugger will show the code jumping forward and backwards alot due to the optimized way variables are stored in registers. This is probably the reason why you can't set your variable (or in some cases see its value) as it has been cleverly distributed between registers for speed, rather than having a direct memory location that the debugger can access.

Compile without optimisations?

Ask them how they ensure their pages continue to be usable when the user has JavaScript turned off or JavaScript isn't available.

There's no One True Answer, but you're fishing for an answer talking about some strategies for Progressive Enhancement.

Progressive Enhancement consists of the following core principles:

• basic content should be accessible to all browsers
• basic functionality should be accessible to all browsers
• sparse, semantic markup contains all content
• enhanced layout is provided by externally linked CSS
• enhanced behavior is provided by [[Unobtrusive JavaScript|unobtrusive]], externally linked JavaScript
• end user browser preferences are respected

            lp.addRule(RelativeLayout.CENTER_IN_PARENT);
            mProgressBar.setScaleY(1.55f);
            mProgressBar.setScaleX(1.55f);
            mProgressBar.setLayoutParams(lp);

            rl.addView(mProgressBar);
            layout.addView(rl, params);
        }
    }

    public void show() {
        if (mProgressBar != null)
            mProgressBar.setVisibility(View.VISIBLE);
    }

    public void hide() {
        if (mProgressBar != null) {
            rl.setClickable(false);
            mProgressBar.setVisibility(View.INVISIBLE);
        }
    }
}

And then call

customProgressBar = new CustomProgressBar (Activity, true);
customProgressBar .show();

To add to the excellent list (given by @CodeCowboyOrg) of situations where OPTION(RECOMPILE) can be very helpful,

6. Table Variables. When you are using table variables, there will not be any pre-built statistics for the table variable, often leading to large differences between estimated and actual rows in the query plan. Using OPTION(RECOMPILE) on queries with table variables allows generation of a query plan that has a much better estimate of the row numbers involved. I had a particularly critical use of a table variable that was unusable, and which I was going to abandon, until I added OPTION(RECOMPILE). The run time went from hours to just a few minutes. That is probably unusual, but in any case, if you are using table variables and working on optimizing, it's well worth seeing whether OPTION(RECOMPILE) makes a difference.

Short answer - no.

You will only be charged for the time that your instance is up and running, in hour increments. If you are using other services in conjunction you may be charged for those but it would be separate from your server instance.

There is an easier way where you don't have to type any code (Ideal for Testing or One-time updates):

Step 1

• Right click on table in the explorer and select "Edit top 100 rows";

Step 2

• Then you can select the rows that you want (Ctrl + Click or Ctrl + A), and Right click and Copy (Note: If you want to add a "where" condition, then Right Click on Grid -> Pane -> SQL Now you can edit Query and add WHERE condition, then Right Click again -> Execute SQL, your required rows will be available to select on bottom)

Step 3

• Follow Step 1 for the target table.

Step 4

• Now go to the end of the grid and the last row will have an asterix (*) in first column (This row is to add new entry). Click on that to select that entire row and then PASTE (Ctrl + V). The cell might have a Red Asterix (indicating that it is not saved)

Step 5

• Click on any other row to trigger the insert statement (the Red Asterix will disappear)

Note - 1: If the columns are not in the correct order as in Target table, you can always follow Step 2, and Select the Columns in the same order as in the Target table

Note - 2 - If you have Identity columns then execute SET IDENTITY_INSERT sometableWithIdentity ON and then follow above steps, and in the end execute SET IDENTITY_INSERT sometableWithIdentity OFF

Instead of running MongoDB with:

sudo mongod

You can use mongod instead if you:

1. Locate the data folder of mongodb (usually ~/data)
2. Add permission to read + write with sudo chmod -R ugo+rw data

If you need to use sudo when running mongodb (sudo mongod), that means you don't have read and write permission on the mongodb data folder

Use the event on handleChange to figure out the element that has changed and then update it. For that you might need to change some property to identify it and update it.

See fiddle https://jsfiddle.net/69z2wepo/6164/

You can use crypto-js.

To use crypto-js, you need to load core.js then md5.js .

A list of URLs are here https://cdnjs.com/libraries/crypto-js

cryptojs is also available in zip form here https://code.google.com/archive/p/crypto-js/downloads

There is an answer from answerer 'amal' in 2013, that is similar to this but a)his link to md5.js no longer works b)he didn't load core.js beforehand, which is necessary.

? HTTP 1.0 (1994)

• It is still in use
• Can be used by a client that cannot deal with chunked (or compressed) server replies

? HTTP 1.1 (1996- 2015)

• Formalizes many extensions to version 1.0
• Supports persistent and pipelined connections
• Supports chunked transfers, compression/decompression
• Supports virtual hosting (a server with a single IP Address hosting multiple domains)
• Supports multiple languages
• Supports byte-range transfers; useful for resuming interrupted data transfers

HTTP 1.1 is an enhancement of HTTP 1.0. The following lists the four major improvements:

1. Efficient use of IP addresses, by allowing multiple domains to be served from a single IP address.

2. Faster response, by allowing a web browser to send multiple requests over a single persistent connection.

3. Faster response for dynamically-generated pages, by support for chunked encoding, which allows a response to be sent before its total length is known.
4. Faster response and great bandwidth savings, by adding cache support.

& is always evaluated in a string context, while + may not concatenate if one of the operands is no string:

"1" + "2" => "12"
"1" + 2   => 3
1 + "2"   => 3
"a" + 2   => type mismatch

This is simply a subtle source of potential bugs and therefore should be avoided. & always means "string concatenation", even if its arguments are non-strings:

"1" & "2" => "12"
"1" &  2  => "12"
 1  & "2" => "12"
 1  &  2  => "12"
"a" &  2  => "a2"

To get the number of votes for a specific item, you would use:

vote_count = Item.objects.filter(votes__contest=contestA).count()

If you wanted a break down of the distribution of votes in a particular contest, I would do something like the following:

contest = Contest.objects.get(pk=contest_id)
votes   = contest.votes_set.select_related()

vote_counts = {}

for vote in votes:
  if not vote_counts.has_key(vote.item.id):
    vote_counts[vote.item.id] = {
      'item': vote.item,
      'count': 0
    }

  vote_counts[vote.item.id]['count'] += 1

This will create dictionary that maps items to number of votes. Not the only way to do this, but it's pretty light on database hits, so will run pretty quickly.

2^31-1 bytes. So, a little less than 2^31-1 characters for varchar(max) and half that for nvarchar(max).

Lazy exceptions occur when you fetch an object typically containing a collection which is lazily loaded, and try to access that collection.

You can avoid this problem by

• accessing the lazy collection within a transaction.
• Initalizing the collection using Hibernate.initialize(obj);
• Fetch the collection in another transaction
• Use Fetch profiles to select lazy/non-lazy fetching runtime
• Set fetch to non-lazy (which is generally not recommended)

Further I would recommend looking at the related links to your right where this question has been answered many times before. Also see Hibernate lazy-load application design.

I think you mean the active state

 button:active{
  //some styling
 }

These are all the possible pseudo states a link can have in CSS:

a:link {color:#FF0000;}    /* unvisited link, same as regular 'a' */
a:hover {color:#FF00FF;}   /* mouse over link */
a:focus {color:#0000FF;}   /* link has focus */
a:active {color:#0000FF;}  /* selected link */
a:visited {color:#00FF00;} /* visited link */

@miyuru. As suggested by him run all the steps.

Ubuntu version 16.04

Still when I ran docker --version it was returning a version. So to uninstall it completely

Again run the dpkg -l | grep -i docker which will list package still there in system.

For example:

ii  docker-ce-cli      5:19.03.6~3-0~ubuntu-xenial               
amd64        Docker CLI: the open-source application container engine

Now remove them as show below :

sudo apt-get purge -y docker-ce-cli

sudo apt-get autoremove -y --purge docker-ce-cli

sudo apt-get autoclean

Hope this will resolve it, as it did in my case.

You could ignore SIGINTs after shutdown starts by calling signal.signal(signal.SIGINT, signal.SIG_IGN) before you start your cleanup code.

Just a simple folder drill down.

sub sample()
    Dim FileSystem As Object
    Dim HostFolder As String

    HostFolder = "C:\"

    Set FileSystem = CreateObject("Scripting.FileSystemObject")
    DoFolder FileSystem.GetFolder(HostFolder)
end  sub

Sub DoFolder(Folder)
    Dim SubFolder
    For Each SubFolder In Folder.SubFolders
        DoFolder SubFolder
    Next
    Dim File
    For Each File In Folder.Files
        ' Operate on each file
    Next
End Sub

You can also use includes

  const isApple = ['iPhone', 'iPad', 'iPod', 'iPad Simulator', 'iPhone Simulator', 'iPod Simulator',].includes(navigator.platform)

Here's the code I used to quickly bind jQuery scrollTo to all anchor links:

// Smooth scroll
$('a[href*=#]').click(function () {
    var hash = $(this).attr('href');
    hash = hash.slice(hash.indexOf('#') + 1);
    $.scrollTo(hash == 'top' ? 0 : 'a[name='+hash+']', 500);
    window.location.hash = '#' + hash;
    return false;
});

Open WSDL file and find:

<soap:operation soapAction="[actionNameIsHere]" style="document"/>

Add to the requests header [request send to service]:

'soapAction' : '[actionNameIsHere]'

This work for me.

For devs. using node-soap [ https://github.com/vpulim/node-soap ] - example:

var soap = require('soap');
var options = {
   ...your options...
   forceSoap12Headers: true
}
soap.createClient(
        wsdl, options,
            function(err, client) {
                if(err) {
                    return callBack(err, result);
                }
                client.addHttpHeader('soapAction', '[actionNameIsHere]');
                ...your code - request send...
            });

Yes, the Map interface will allow you to store Arrays as values. Here's a very simple example:

int[] val = {1, 2, 3};
Map<String, int[]> map = new HashMap<String, int[]>();
map.put("KEY1", val);

Also, depending on your use case you may want to look at the Multimap support offered by guava.

The only easy way to do this is to use snprintf to print to a buffer that's long enough to hold the entire, exact value, then truncate it as a string. Something like:

char buf[2*(DBL_MANT_DIG + DBL_MAX_EXP)];
snprintf(buf, sizeof buf, "%.*f", (int)sizeof buf, x);
char *p = strchr(buf, '.'); // beware locale-specific radix char, though!
p[2+1] = 0;
puts(buf);

@Steve Hobbs' answer is probably the best, but some of your other solutions could have worked. For example, @Html.Label(ViewBag.CurrentPath); will probably work with an explicit cast, like @Html.Label((string)ViewBag.CurrentPath);. Also, your reference to currentPath in @Html.Label(ViewData["CurrentPath"].ToString()); is capitalized, wherein your other code it is not, which is probably why you were getting null reference exceptions.

Is it possible that you can avoid using wsdl2java? You can straight away use CXF FrontEnd APIs to invoke your SOAP Webservice. The only catch is that you need to create your SEI and VOs on your client end. Here is a sample code.

package com.aranin.weblog4j.client;

import com.aranin.weblog4j.services.BookShelfService;
import com.aranin.weblog4j.vo.BookVO;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

public class DemoClient {
    public static void main(String[] args){
        String serviceUrl = "http://localhost:8080/weblog4jdemo/bookshelfservice";
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(BookShelfService.class);
        factory.setAddress(serviceUrl);
        BookShelfService bookService = (BookShelfService) factory.create();

        //insert book
        BookVO bookVO = new BookVO();
        bookVO.setAuthor("Issac Asimov");
        bookVO.setBookName("Foundation and Earth");

        String result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        bookVO = new BookVO();
        bookVO.setAuthor("Issac Asimov");
        bookVO.setBookName("Foundation and Empire");

        result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        bookVO = new BookVO();
        bookVO.setAuthor("Arthur C Clarke");
        bookVO.setBookName("Rama Revealed");

        result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        //retrieve book

        bookVO = bookService.getBook("Foundation and Earth");

        System.out.println("book name : " + bookVO.getBookName());
        System.out.println("book author : " + bookVO.getAuthor());

    }
}

You should use the * operator, like foo(*values) Read the Python doc unpackaging argument lists.

Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/

def foo(x,y,z):
   return "%d, %d, %d" % (x,y,z)

values = [1,2,3]

# the solution.
foo(*values)

Now days I believe it's preferred to use a function form of typeof() so...

if(filename === undefined || typeof(filename) !== "string" || filename === "") {
   console.log("no filename aborted.");
   return;
}

This one can also be used with less effort I believe (but I am in MVC 5)

@Html.Description(model => model.Story, 20, 50, new { })

I had a similar problem. The error is raised, but the code is compiled and linked. The error was caused by the Error Parser using a different configuration than the one that is compiled.

The error parser configuration was only valid for the Linux configuration of my software. My active configuration was set for MinGW and Windows.

Solution:

• In Elipse under Windows->Preferences->C/C++->Indexer set Build Configuration for the indexer to Use active build configuration.
• Clean and rebuild, otherwise the old errors will remain visible

[tabviewController.view setBackgroundColor:[UIColor blackColor]];

Did it for me [UIColor blackColor] might be your background color, and tabviewController is your UITabBarController if you are using it!

You will need to configure you IIS (assuming this is the web server your are/will using) allowing access from WLAN/LAN to specific users (or anonymous). Allow IIS trought your firewall if you have one.

Your application won't need to be changed, that's just networking problems ans configuration you will have to face to allow acces only trought LAN and WLAN.

Datatables have a .Select method, which returns a rows array according to the criteria you specify. Something like this:

Dim oRows() As DataRow

oRows = dtCountries.Select("CountryName = '" & userinput & "'")

If oRows.Count = 0 Then
   ' No rows found
Else
   ' At least one row found. Could be more than one
End If

Of course, if userinput contains ' character, it would raise an exception (like if you query the database). You should escape the ' characters (I use a function to do that).

You can send some flag to stop while loop in server

for example

Server side:

import socket
s = socket.socket()
s.bind(("localhost", 5000))
s.listen(1)
c,a = s.accept()
filetodown = open("img.png", "wb")
while True:
   print("Receiving....")
   data = c.recv(1024)
   if data == b"DONE":
           print("Done Receiving.")
           break
   filetodown.write(data)
filetodown.close()
c.send("Thank you for connecting.")
c.shutdown(2)
c.close()
s.close()
#Done :)

Client side:

import socket
s = socket.socket()
s.connect(("localhost", 5000))
filetosend = open("img.png", "rb")
data = filetosend.read(1024)
while data:
    print("Sending...")
    s.send(data)
    data = filetosend.read(1024)
filetosend.close()
s.send(b"DONE")
print("Done Sending.")
print(s.recv(1024))
s.shutdown(2)
s.close()
#Done :)

Different file name which posted as "recfile" at <input type="file" name='recfile' placeholder="Select file"/> and received as "file" at upload.single('file')

Solution : make sure both sent and received file are similar upload.single('recfile')

This is really more of a serverfault-type question, but you can use netstat.

something like:

 # netstat -lpnt | grep 6000 | grep ssh

This will tell you if there's an ssh process listening on the specified port. it will also tell you the PID of the process.

If you really want to double-check that the ssh process was started with the right options, you can then look up the process by PID in something like

# ps aux | grep PID

Adapt this example to your code

HTML

<div class="img-holder">
    <img src="images/img-1.png" alt="image description"/>
    <a class="link" href=""></a>
</div>

CSS

.img-holder {position: relative;}
.img-holder .link {
    position: absolute;
    bottom: 10px; /*your button position*/
    right: 10px; /*your button position*/
}

I had the same issue:

But the situation was, every time i try to enter:

/usr/local/mysql/support-files/mysql.server start

a file named localhost.pid is created instead of iMax0.local.pid which was stated in the error:

ERROR! The server quit without updating PID file (/usr/local/mysql/data/iMax0.local.pid).

Solution that works for me was copying localhost.pid and renaming it to iMax0.local.pid.

As of API 28 at least:

1. Open Settings app in emulator
2. Search for "Storage" select search result for it
3. Select Photos & Videos in Storage
4. Select Images
5. Drag an image onto the emulator, it won't immediately show up
6. From the AVD Manager in Android Studio, cold boot the emulator

The photos you've dragged in are now available.

If you've tried the other answers and your include file still can't be found, here are some additional debugging steps and sanity-checks:

• Ensure that you are building to a platform that is supported by your code. (If not, consider removing this platform as a target)
• Verify that the filename/path is correct. Modify your source code to #include the whole absolute path of the header file instead, and see if the file can be found now. If not, copy-paste the path from your source code into a command line to validate that the file exists at that full path with no typos. Open the header file to ensure you have read access. (Change the source code back when done.)
• If you've already added the path to Additional Include Directories, try clicking the drop-down combo box for Additional Include Directories, and select <Edit...>. This will show you evaluated values of paths. (If it does not show the correct evaluated values, variables in your path might not be set. Click Macros>> to see variables.) Copy-paste the evaluated path into windows explorer to validate that the path exists.
• Create a new empty C++ "Windows Console Application" project. Set just the one Include Directory, and #include just the one file in your main.cpp, and see if that builds.

I was faces this issue but after change object into str, problem solved. str(fname).isalpha():

You said:

I want them to always come out as Tanzanian time and not in the local times that various collaborator are in.

If this is the case, then you should not use UTC. All you need to do is to use a DATETIME type in MySQL instead of a TIMESTAMP type.

From the MySQL documentation:

MySQL converts TIMESTAMP values from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. (This does not occur for other types such as DATETIME.)

If you are already using a DATETIME type, then you must be not setting it by the local time to begin with. You'll need to focus less on the database, and more on your application code - which you didn't show here. The problem, and the solution, will vary drastically depending on language, so be sure to tag the question with the appropriate language of your application code.

After testing several unreliable implementations, the algorithm that provided satisfactory results regarding the CW/CCW orientation out of the box was the one, posted by OP in this thread (shoelace_formula_3).

As always, a positive number represents a CW orientation, whereas a negative number CCW.

See the documentation on ?merge, which states:

By default the data frames are merged on the columns with names they both have, 
 but separate specifications of the columns can be given by by.x and by.y.

This clearly implies that merge will merge data frames based on more than one column. From the final example given in the documentation:

x <- data.frame(k1=c(NA,NA,3,4,5), k2=c(1,NA,NA,4,5), data=1:5)
y <- data.frame(k1=c(NA,2,NA,4,5), k2=c(NA,NA,3,4,5), data=1:5)
merge(x, y, by=c("k1","k2")) # NA's match

This example was meant to demonstrate the use of incomparables, but it illustrates merging using multiple columns as well. You can also specify separate columns in each of x and y using by.x and by.y.

Using true/false as the value will have the field pre-filled if the model passed to the form has this attribute already filled:

= f.radio_button(:public?, true)
= f.label(:public?, "yes", value: true)
= f.radio_button(:public?, false)
= f.label(:public?, "no", value: false)

In the simple case you can do:

var user = cnn.Query<User>("spGetUser", new {Id = 1}, 
        commandType: CommandType.StoredProcedure).First();

If you want something more fancy, you can do:

 var p = new DynamicParameters();
 p.Add("@a", 11);
 p.Add("@b", dbType: DbType.Int32, direction: ParameterDirection.Output);
 p.Add("@c", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);

 cnn.Execute("spMagicProc", p, commandType: CommandType.StoredProcedure); 

 int b = p.Get<int>("@b");
 int c = p.Get<int>("@c"); 

Additionally you can use exec in a batch, but that is more clunky.

Currently you are sending the data as typical POST values, which look like this:

first_name=somename&last_name=somesurname

If you want to send data as json you need to create an object with data and stringify it.

data: JSON.stringify(someobject)

It's a new era and with Python 3.6.1 dictionaries now retain their order. These semantics aren't explicit because that would require BDFL approval. But Raymond Hettinger is the next best thing (and funnier) and he makes a pretty strong case that dictionaries will be ordered for a very long time.

So now it's easy to create slices of a dictionary:

test_dict = {
                'first':  1,

My answer is just a conceptual one without any source code. It might be useful for some readers like myself to understand.

It depends on your initial approach on how you architecture your app. There are basically two approaches.

1. You create one activity (base activity) and all the other views and screens will be fragments. That base activity contains the implementation for Drawer and Coordinator Layouts. It is actually my preferred way of doing because having small self-contained fragments will make app development easier and smoother.

2. If you have started your app development with activities, one for each screen , then you will probably create base activity, and all other activity extends from it. The base activity will contain the code for drawer and coordinator implementation. Any activity that needs drawer implementation can extend from base activity.

I would personally prefer avoiding to use fragments and activities mixed without any organizing. That makes the development more difficult and get you stuck eventually. If you have done it, refactor your code.

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

I tried it with Java on Linux. The following possibilities are OK:

file:///home/userId/aaaa.html
file:/home/userId/aaaa.html
file:aaaa.html  (if current directory is /home/userId)

not working is:

file://aaaa.html

Overloading is defining functions that have similar signatures, yet have different parameters. Overriding is only pertinent to derived classes, where the parent class has defined a method and the derived class wishes to override that method.

In PHP, you can only overload methods using the magic method __call.

An example of overriding:

<?php

class Foo {
   function myFoo() {
      return "Foo";
   }
}

class Bar extends Foo {
   function myFoo() {
      return "Bar";
   }
}

$foo = new Foo;
$bar = new Bar;
echo($foo->myFoo()); //"Foo"
echo($bar->myFoo()); //"Bar"
?>

If you want a certain message, use this:

String phoneNo = "";//The phone number you want to text
String sms= "";//The message you want to text to the phone

Intent smsIntent = new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", phoneNo, null));
smsIntent.putExtra("sms_body",sms);
startActivity(smsIntent);

In mdcharm it is like this:

* [Descripción](#descripcion)
* [Funcionamiento](#funcionamiento)
* [Instalación](#instalacion)
* [Configuración](#configuracion)

### Descripción {#descripcion}
### Funcionamiento {#funcionamiento}

User Defined Class Array List Example

import java.util.*;  

public class UserDefinedClassInArrayList {

    public static void main(String[] args) {

        //Creating user defined class objects  
        Student s1=new Student(1,"AAA",13);  
        Student s2=new Student(2,"BBB",14);  
        Student s3=new Student(3,"CCC",15); 

        ArrayList<Student> al=new ArrayList<Student>();
        al.add(s1);
        al.add(s2);  
        al.add(s3);  

        Iterator itr=al.iterator();  

        //traverse elements of ArrayList object  
        while(itr.hasNext()){  
            Student st=(Student)itr.next();  
            System.out.println(st.rollno+" "+st.name+" "+st.age);  
        }  
    }
}

class Student{  
    int rollno;  
    String name;  
    int age;  
    Student(int rollno,String name,int age){  
        this.rollno=rollno;  
        this.name=name;  
        this.age=age;  
    }  
} 

Program Output:

1 AAA 13

2 BBB 14

3 CCC 15

There is likely whitespace outside of your php tags.

Use shortcut Alt+Shift+W or navigate to Windows->Show View->Project Explorer

<T> is a generic and can usually be read as "of type T". It depends on the type to the left of the <> what it actually means.

I don't know what a Pool or PoolFactory is, but you also mention ArrayList<T>, which is a standard Java class, so I'll talk to that.

Usually, you won't see "T" in there, you'll see another type. So if you see ArrayList<Integer> for example, that means "An ArrayList of Integers." Many classes use generics to constrain the type of the elements in a container, for example. Another example is HashMap<String, Integer>, which means "a map with String keys and Integer values."

Your Pool example is a bit different, because there you are defining a class. So in that case, you are creating a class that somebody else could instantiate with a particular type in place of T. For example, I could create an object of type Pool<String> using your class definition. That would mean two things:

• My Pool<String> would have an interface PoolFactory<String> with a createObject method that returns Strings.
• Internally, the Pool<String> would contain an ArrayList of Strings.

This is great news, because at another time, I could come along and create a Pool<Integer> which would use the same code, but have Integer wherever you see T in the source.

Simplified version for Oracle. If you don't want to create OracleParameter

var sql = "Update [User] SET FirstName = :p0 WHERE Id = :p1";
context.Database.ExecuteSqlCommand(sql, firstName, id);

Use atoi() from <stdlib.h>

http://linux.die.net/man/3/atoi

Or, write your own atoi() function which will convert char* to int

int a2i(const char *s)
{
  int sign=1;
  if(*s == '-'){
    sign = -1;
    s++;
  }
  int num=0;
  while(*s){
    num=((*s)-'0')+num*10;
    s++;   
  }
  return num*sign;
}

Using print function without parentheses works with older versions of Python but is no longer supported on Python3, so you have to put the arguments inside parentheses. However, there are workarounds, as mentioned in the answers to this question. Since the support for Python2 has ended in Jan 1st 2020, the answer has been modified to be compatible with Python3.

You could do any of these (and there may be other ways):

(1)  print("First number is {} and second number is {}".format(first, second))
(1b) print("First number is {first} and number is {second}".format(first=first, second=second)) 

or

(2) print('First number is', first, 'second number is', second) 

(Note: A space will be automatically added afterwards when separated from a comma)

or

(3) print('First number %d and second number is %d' % (first, second))

or

(4) print('First number is ' + str(first) + ' second number is' + str(second))
  

Using format() (1/1b) is preferred where available.

Since this is a matter of finding files, let's use find!

Using GNU find you can use the -regex option to find those files in the tree of directories whose extension is either .h or .cpp:

find -type f -regex ".*\.\(h\|cpp\)"
#            ^^^^^^^^^^^^^^^^^^^^^^^

Then, it is just a matter of executing grep on each of its results:

find -type f -regex ".*\.\(h\|cpp\)" -exec grep "your pattern" {} +

If you don't have this distribution of find you have to use an approach like Amir Afghani's, using -o to concatenate options (the name is either ending with .h or with .cpp):

find -type f \( -name '*.h' -o -name '*.cpp' \) -exec grep "your pattern" {} +
#            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

And if you really want to use grep, follow the syntax indicated to --include:

grep "your pattern" -r --include=*.{cpp,h}
#                      ^^^^^^^^^^^^^^^^^^^

Specify the type of the pointer to your comparison function as the 3rd type into the map, and provide the function pointer to the map constructor:
map<keyType, valueType, typeOfPointerToFunction> mapName(pointerToComparisonFunction);

Take a look at the example below for providing a comparison function to a map, with vector iterator as key and int as value.

#include "headers.h"

bool int_vector_iter_comp(const vector<int>::iterator iter1, const vector<int>::iterator iter2) {
    return *iter1 < *iter2;
}

int main() {
    // Without providing custom comparison function
    map<vector<int>::iterator, int> default_comparison;

    // Providing custom comparison function
    // Basic version
    map<vector<int>::iterator, int,
        bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2)>
        basic(int_vector_iter_comp);

    // use decltype
    map<vector<int>::iterator, int, decltype(int_vector_iter_comp)*> with_decltype(&int_vector_iter_comp);

    // Use type alias or using
    typedef bool my_predicate(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate*> with_typedef(&int_vector_iter_comp);

    using my_predicate_pointer_type = bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate_pointer_type> with_using(&int_vector_iter_comp);


    // Testing 
    vector<int> v = {1, 2, 3};

    default_comparison.insert(pair<vector<int>::iterator, int>({v.end(), 0}));
    default_comparison.insert(pair<vector<int>::iterator, int>({v.begin(), 0}));
    default_comparison.insert(pair<vector<int>::iterator, int>({v.begin(), 1}));
    default_comparison.insert(pair<vector<int>::iterator, int>({v.begin() + 1, 1}));

    cout << "size: " << default_comparison.size() << endl;
    for (auto& p : default_comparison) {
        cout << *(p.first) << ": " << p.second << endl;
    }

    basic.insert(pair<vector<int>::iterator, int>({v.end(), 0}));
    basic.insert(pair<vector<int>::iterator, int>({v.begin(), 0}));
    basic.insert(pair<vector<int>::iterator, int>({v.begin(), 1}));
    basic.insert(pair<vector<int>::iterator, int>({v.begin() + 1, 1}));

    cout << "size: " << basic.size() << endl;
    for (auto& p : basic) {
        cout << *(p.first) << ": " << p.second << endl;
    }

    with_decltype.insert(pair<vector<int>::iterator, int>({v.end(), 0}));
    with_decltype.insert(pair<vector<int>::iterator, int>({v.begin(), 0}));
    with_decltype.insert(pair<vector<int>::iterator, int>({v.begin(), 1}));
    with_decltype.insert(pair<vector<int>::iterator, int>({v.begin() + 1, 1}));

    cout << "size: " << with_decltype.size() << endl;
    for (auto& p : with_decltype) {
        cout << *(p.first) << ": " << p.second << endl;
    }

    with_typedef.insert(pair<vector<int>::iterator, int>({v.end(), 0}));
    with_typedef.insert(pair<vector<int>::iterator, int>({v.begin(), 0}));
    with_typedef.insert(pair<vector<int>::iterator, int>({v.begin(), 1}));
    with_typedef.insert(pair<vector<int>::iterator, int>({v.begin() + 1, 1}));

    cout << "size: " << with_typedef.size() << endl;
    for (auto& p : with_typedef) {
        cout << *(p.first) << ": " << p.second << endl;
    }
}

Go to /etc/apache2/apache2.conf

You have to edit that file (you should have root permission). Change directory text as bellow:

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted

Now you have to restart apache.

service apache2 restart

I recommend using the os module to avoid trouble in cross-platform. (windows,linux,mac)

Cause if the directory doesn't exists, it will return an exception.

import os

filepath = os.path.join('c:/your/full/path', 'filename')
if not os.path.exists('c:/your/full/path'):
    os.makedirs('c:/your/full/path')
f = open(filepath, "a")

If this will be a function for a system or something, you can improve it by adding try/except for error control.

If you are using Toolbar, you don't need those solutions. You only have to change the theme of the toolbar

app:theme="@style/ThemeOverlay.AppCompat.Light"

app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"

If you are using a dark.actionBar your back button is going to be white else if you are using light actionbar theme it is going to be black.

Usually it is a simple as adding apply plugin: "eclipse" in your build.gradle and running

cd myProject/
gradle eclipse

and then refreshing your Eclipse project.

Occasionally you'll need to adjust build.gradle to generate Eclipse settings in some very specific way.

There is gradle support for Eclipse if you are using STS, but I'm not sure how good it is.

The only IDE I know that has decent native support for gradle is IntelliJ IDEA. It can do full import of gradle projects from GUI. There is a free Community Edition that you can try.

Here is simple example of taking input from user on console based application: You can use readLine(). Take input from console for first number then press enter. After that take input for second number as shown in the image below:

func solveMefirst(firstNo: Int , secondNo: Int) -> Int {
    return firstNo + secondNo
}

let num1 = readLine()
let num2 = readLine()

var IntNum1 = Int(num1!)
var IntNum2 = Int(num2!)

let sum = solveMefirst(IntNum1!, secondNo: IntNum2!)
print(sum)

Solution that will work for multiple scopes and multiple variables within those scopes

This service was based off of Anton's answer, but is more extensible and will work across multiple scopes and allows the selection of multiple scope variables in the same scope. It uses the route path to index each scope, and then the scope variable names to index one level deeper.

Create service with this code:

angular.module('restoreScope', []).factory('restoreScope', ['$rootScope', '$route', function ($rootScope, $route) {

    var getOrRegisterScopeVariable = function (scope, name, defaultValue, storedScope) {
        if (storedScope[name] == null) {
            storedScope[name] = defaultValue;
        }
        scope[name] = storedScope[name];
    }

    var service = {

        GetOrRegisterScopeVariables: function (names, defaultValues) {
            var scope = $route.current.locals.$scope;
            var storedBaseScope = angular.fromJson(sessionStorage.restoreScope);
            if (storedBaseScope == null) {
                storedBaseScope = {};
            }
            // stored scope is indexed by route name
            var storedScope = storedBaseScope[$route.current.$$route.originalPath];
            if (storedScope == null) {
                storedScope = {};
            }
            if (typeof names === "string") {
                getOrRegisterScopeVariable(scope, names, defaultValues, storedScope);
            } else if (Array.isArray(names)) {
                angular.forEach(names, function (name, i) {
                    getOrRegisterScopeVariable(scope, name, defaultValues[i], storedScope);
                });
            } else {
                console.error("First argument to GetOrRegisterScopeVariables is not a string or array");
            }
            // save stored scope back off
            storedBaseScope[$route.current.$$route.originalPath] = storedScope;
            sessionStorage.restoreScope = angular.toJson(storedBaseScope);
        },

        SaveState: function () {
            // get current scope
            var scope = $route.current.locals.$scope;
            var storedBaseScope = angular.fromJson(sessionStorage.restoreScope);

            // save off scope based on registered indexes
            angular.forEach(storedBaseScope[$route.current.$$route.originalPath], function (item, i) {
                storedBaseScope[$route.current.$$route.originalPath][i] = scope[i];
            });

            sessionStorage.restoreScope = angular.toJson(storedBaseScope);
        }
    }

    $rootScope.$on("savestate", service.SaveState);

    return service;
}]);

Add this code to your run function in your app module:

$rootScope.$on('$locationChangeStart', function (event, next, current) {
    $rootScope.$broadcast('savestate');
});

window.onbeforeunload = function (event) {
    $rootScope.$broadcast('savestate');
};

Inject the restoreScope service into your controller (example below):

function My1Ctrl($scope, restoreScope) {
    restoreScope.GetOrRegisterScopeVariables([
         // scope variable name(s)
        'user',
        'anotherUser'
    ],[
        // default value(s)
        { name: 'user name', email: '[email protected]' },
        { name: 'another user name', email: '[email protected]' }
    ]);
}

The above example will initialize $scope.user to the stored value, otherwise will default to the provided value and save that off. If the page is closed, refreshed, or the route is changed, the current values of all registered scope variables will be saved off, and will be restored the next time the route/page is visited.

I put above-mentioned methods together using ax instead of plt

import numpy as np
import matplotlib.pyplot as plt

x = range(100)
y = x

fig, ax = plt.subplots(1, 1, figsize=(7.2, 7.2))
ax.plot(x, y);

# method 1
print(ax.get_xlim())
print(ax.get_xlim())
# method 2
print(ax.axis())

In my case it was related to vs-code running on my Linux machine. I ignored a warning which popped up about file watcher bla bla. The solution is on the vs-code docs page for linux https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc

The solution is almost same (if not same) as the accepted answers, just has more explanation for anyone who gets here after running into the issues from vs-code.

You can use json_decode() to convert a json string to a PHP object/array.

Eg.

Input:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));
var_dump(json_decode($json, true));

Output:

object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

array(5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

Few Points to remember:

• json_decode requires the string to be a valid json else it will return NULL.
• In the event of a failure to decode, json_last_error() can be used to determine the exact nature of the error.
• Make sure you pass in utf8 content, or json_decode may error out and just return a NULL value.

We were seeing this same issue in one of our old projects that was targeting Framework 4.5.2. I tried several scenarios including all of the ones listed above: target 4.6.1, add System.ValueTuple package, delete bin, obj, and .vs folders. No dice. Repeat the same process for 4.7.2. Then tried removing the System.ValueTuple package since I was targeting 4.7.2 as one commenter suggested. Still nothing. Checked csproj file reference path. Looks right. Even dropped back down to 4.5.2 and installing the package again. All this with several VS restarts and deleting the same folders several times. Literally nothing worked.

I had to refactor to use a struct instead. I hope others don't continue to run into this issue in the future but thought this might be helpful if you end up as stumped up as we were.

Matthew's answer is correct:

list.get(0);

To do what you tried:

list[0];

you'll have to wait until Java 7 is released:

Here's an interesting presentation by Mark Reinhold about Java 7

_{It looks like parleys site is currently down, try later :(}

The first answer will not pass through all the points. This graph will exactly pass through all the points and will be a perfect curve with the points as [{x:,y:}] n such points.

var points = [{x:1,y:1},{x:2,y:3},{x:3,y:4},{x:4,y:2},{x:5,y:6}] //took 5 example points
ctx.moveTo((points[0].x), points[0].y);

for(var i = 0; i < points.length-1; i ++)
{

  var x_mid = (points[i].x + points[i+1].x) / 2;
  var y_mid = (points[i].y + points[i+1].y) / 2;
  var cp_x1 = (x_mid + points[i].x) / 2;
  var cp_x2 = (x_mid + points[i+1].x) / 2;
  ctx.quadraticCurveTo(cp_x1,points[i].y ,x_mid, y_mid);
  ctx.quadraticCurveTo(cp_x2,points[i+1].y ,points[i+1].x,points[i+1].y);
}

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

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

print 'Value is "%d"' % value

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

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

No, no, no.

These answers are all wrong. There is a fundamental absence of knowledge in your brain that I'm going to remedy right now.

Your major issue here is your naming scheme. It's verbose, contains undesirable characters, and is horribly inconsistent.

First: A table that is called Salesperson does not need to have each field in the table called Salesperson.Salesperson number, Salesperson.Salesperson email. You're already in the table Salesperson. Everything in this table relates to Salesperson. You don't have to keep saying it.

Instead use ID, Email. Don't use Number because that's probably a reserved word. Do you really endeavour to type [] around every field name for the lifespan of your database?

Primary keys on a table called Student can either be ID or StudentID but be consistent. Foreign keys should only be named by the table it points to followed by ID. For example: Student.ID and Appointment.StudentID. ID is always capitalized. I don't care if your IDE tells you not to because everywhere but your IDE will be ID. Even Access likes ID.

Second: Name all your fields without spaces or special characters and keep them as short as possible and if they conflict with a reserved word, find another word.

Instead of: phone number use PhoneNumber or even better, simply, Phone. If you choose what time user made the withdrawal, you're going to have to type that in every single time.

Third: And this one is the most important one: Always be consistent in whatever naming scheme you choose. You should be able to say, "I need the postal code from that table; its name is going to be PostalCode." You should know that without even having to look it up because you were consistent in your naming convention.

Recap: Terse, not verbose. Keep names short with no spaces, don't repeat the table name, don't use reserved words, and capitalize each word. Above all, be consistent.

I hope you take my advice. This is the right way to do it. My answer is the right one. You should be extremely pedantic with your naming scheme to the point of absolute obsession for the rest of your lives on this planet.

NOTE:You actually have to change the field name in the design view of the table and in the query.

You have to return JSON error object yourself after setting the StatusCode, like so ...

if (BadRequest)
{
    Dictionary<string, object> error = new Dictionary<string, object>();
    error.Add("ErrorCode", -1);
    error.Add("ErrorMessage", "Something really bad happened");
    return Json(error);
}

Another way is to have a JsonErrorModel and populate it

public class JsonErrorModel
{
    public int ErrorCode { get; set;}

    public string ErrorMessage { get; set; }
}

public ActionResult SomeMethod()
{

    if (BadRequest)
    {
        var error = new JsonErrorModel
        {
            ErrorCode = -1,
            ErrorMessage = "Something really bad happened"
        };

        return Json(error);
    }

   //Return valid response
}

Ran into this issue, npm i @ionic/app-scripts was the only thing that worked.

I think the simplest way to use the newest version of Node.js is to get the newest Node.js pkg file in the website https://nodejs.org/en/download/current/ if you want to use different version of Node.js you can use nvm or n to manage it.

you could use setBackgroundResource() instead i.e. relativeLayout.setBackgroundResource(R.drawable.back);

this works for me.

I use:

ls -d */ | cut -f1 -d'/'

This creates a single column without a trailing slash - useful in scripts.

Use Path.parent from the pathlib module:

from pathlib import Path

# ...

Path(__file__).parent

You can use multiple calls to parent to go further in the path:

Path(__file__).parent.parent

A list of the few remaining cosmetic and packaging differences between Oracle JDK 11 and OpenJDK 11 can be found in this blog post:

https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

In short:

• Oracle JDK 11 emits a warning when using the -XX:+UnlockCommercialFeatures option,
• it can be configured to provide usage log data to the “Advanced Management Console” tool,
• it has always required third party cryptographic providers to be signed by a known certificate,
• it will continue to include installers, branding and JRE packaging,
• while the javac --release command behaves slightly differently for the Java 9 and Java 10 targets, and

Is there anything wrong with pure string operations:

url = 'http://stackoverflow.com/questions/9626535/get-domain-name-from-url'
parts = url.split('//', 1)
print parts[0]+'//'+parts[1].split('/', 1)[0]
>>> http://stackoverflow.com

If you prefer having a trailing slash appended, extend this script a bit like so:

parts = url.split('//', 1)
base = parts[0]+'//'+parts[1].split('/', 1)[0]
print base + (len(url) > len(base) and url[len(base)]=='/'and'/' or '')

That can probably be optimized a bit ...

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

String.format() to the rescue!!

Swift 4 and above

I have created an extension

extension UIViewController {
  public func addActionSheetForiPad(actionSheet: UIAlertController) {
    if let popoverPresentationController = actionSheet.popoverPresentationController {
      popoverPresentationController.sourceView = self.view
      popoverPresentationController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
      popoverPresentationController.permittedArrowDirections = []
    }
  }
}

How to use:

let actionSheetVC = UIAlertController(title: "Title", message: nil, preferredStyle: .actionSheet)
addActionSheetForIpad(actionSheet: actionSheetVC)
present(actionSheetVC, animated: true, completion: nil)

An empty plot with some texts which are set position.

plot(1:10, 1:10,xaxt="n",yaxt="n",bty="n",pch="",ylab="",xlab="", main="", sub="")
mtext("eee", side = 3, line = -0.3, adj = 0.5)
text(5, 10.4, "ddd")
text(5, 7, "ccc")

I know this is an old question, but if you would like to have the <input> be a child of <label> instead of having them separate, here is a pure CSS way that you could accomplish it:

:checked + span { font-weight: bold; }

Then just wrap the text with a <span>:

<label>
   <input type="radio" name="test" />
   <span>Radio number one</span>
</label>

See it on JSFiddle.

I know you are using Datepicker, but for some people who are just using HTML5 input date like me, there is an example how you can do the same: JSFiddle Link

$('#start_date').change(function(){
  var start_date = $(this).val();
  $('#end_date').prop({
    min: start_date
  });
});


/*  prop() method works since jquery 1.6, if you are using a previus version, you can use attr() method.*/

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

int arsize(int st1[]) {
    int i = 0;
    for (i; !(st1[i] & (1 << 30)); i++);
    return i;
}

This works for me :)

The 2nd parameter in the get call is a config object. You want something like this:

$http
    .get('accept.php', {
        params: {
            source: link,
            category_id: category
        }
     })
     .success(function (data,status) {
          $scope.info_show = data
     });

See the Arguments section of http://docs.angularjs.org/api/ng.$http for more detail

A lambda is an anonymous function:

>>> f = lambda: 'foo'
>>> print f()
foo

It is often used in functions such as sorted() that take a callable as a parameter (often the key keyword parameter). You could provide an existing function instead of a lambda there too, as long as it is a callable object.

Take the sorted() function as an example. It'll return the given iterable in sorted order:

>>> sorted(['Some', 'words', 'sort', 'differently'])
['Some', 'differently', 'sort', 'words']

but that sorts uppercased words before words that are lowercased. Using the key keyword you can change each entry so it'll be sorted differently. We could lowercase all the words before sorting, for example:

>>> def lowercased(word): return word.lower()
...
>>> lowercased('Some')
'some'
>>> sorted(['Some', 'words', 'sort', 'differently'], key=lowercased)
['differently', 'Some', 'sort', 'words']

We had to create a separate function for that, we could not inline the def lowercased() line into the sorted() expression:

>>> sorted(['Some', 'words', 'sort', 'differently'], key=def lowercased(word): return word.lower())
  File "<stdin>", line 1
    sorted(['Some', 'words', 'sort', 'differently'], key=def lowercased(word): return word.lower())
                                                           ^
SyntaxError: invalid syntax

A lambda on the other hand, can be specified directly, inline in the sorted() expression:

 >>> sorted(['Some', 'words', 'sort', 'differently'], key=lambda word: word.lower())
['differently', 'Some', 'sort', 'words']

Lambdas are limited to one expression only, the result of which is the return value.

There are loads of places in the Python library, including built-in functions, that take a callable as keyword or positional argument. There are too many to name here, and they often play a different role.

To rethrow do

 throw $e;

not the message.

To get the exact file name from the URI, I would use this method:

<?php
    $file1 =basename("http://localhost/eFEIS/agency_application_form.php?formid=1&task=edit") ;

    //basename($_SERVER['REQUEST_URI']); // Or use this to get the URI dynamically.

    echo $basename = substr($file1, 0, strpos($file1, '?'));
?>

In addition to the steps below, you may want to also remove the .gitignore file.

• Consider removing the .gitignore file if you want to remove any trace of Git in your project.

• ** Consider leaving the .gitignore file if you would ever want reincorporate Git into the project.

Some frameworks may automatically produce the .gitignore file so you may want to leave it.

Linux, Mac, or Unix based operating systems

Open a terminal and navigate to the directory of your project, i.e. - cd path_to_your_project.

Run this command:

rm -rf .git*

This will remove the Git tracking and metadata from your project. If you want to keep the metadata (such as .gitignore and .gitkeep), you can delete only the tracking by running rm -rf .git.

Windows

Using the command prompt

The rmdir or rd command will not delete/remove any hidden files or folders within the directory you specify, so you should use the del command to be sure that all files are removed from the .git folder.

1. Open the command prompt

   1. Either click Start then Run or hit the key and r at the same time.

   2. Type cmd and hit enter

2. Navigate to the project directory, i.e. - cd path_to_your_project

3. Run these commands

   1. del /F /S /Q /A .git

   2. rmdir .git

The first command removes all files and folder within the .git folder. The second removes the .git folder itself.

No command prompt

1. Open the file explorer and navigate to your project

2. Show hidden files and folders - refer to this article for a visual guide

   1. In the view menu on the toolbar, select Options

   2. In the Advanced Settings section, find Hidden files and Folders under the Files and Folders list and select Show hidden files and folders

3. Close the options menu and you should see all hidden folders and files including the .git folder.

   Delete the .git folder Delete the .gitignore file ** (see note at the top of this answer)

The original poster is asking on how to open a link on a new tab. So this is how I have done it in C#.

        IWebDriver driver = new ChromeDriver();
        driver.Manage().Window.Maximize();
        driver.Navigate().GoToUrl("https://microsoft.com");
        IWebElement eventlink = driver.FindElement(By.Id("uhfLogo"));
        Actions action = new Actions(driver);
        action.KeyDown(Keys.Control).MoveToElement(eventlink).Click().Perform(); 

This actually performs a Control+Click on the selected element in order to open the link in a new tab.

If you tried myList|length and myList|length_is and its not getting desired results, then you should use myList.count

It sounds maybe like you have the same issue as i do. instead of using MP4, is 3GPP possible? i think i used like HandBrake or something as the video converter... you just need to make sure you have the right encoder, like H.264x or something. sorry for being a little vague, it's been a while. Also, if it's possible, don't bother worrying about android 2.1 anymore, and also, something things just WILL NOT WORK IN EMULATOR. so if it works on a lot of devices, then just assume it works (especially with different manufacurers)

here, you can read my problem and how i solved the issue (after a long time and no one had an answer). i explained in a lot more detail here: android media player not working

This post is a little bit old, but here is another easy solution for getting data related to Call logs content provider in Android:

Use this lib: https://github.com/EverythingMe/easy-content-providers

Get all calls:

CallsProvider callsProvider = new CallsProvider(context);
List<Call> calls = callsProvider.getCalls().getList();

Each Call has all fields, so you can get any info you need:
callDate, duration, number, type(INCOMING, OUTGOING, MISSED), isRead, ...

It works with List or Cursor and there is a sample app to see how it looks and works.

In fact, there is a support for all Android content providers like: Contacts, SMS, Calendar, ... Full doc with all options: https://github.com/EverythingMe/easy-content-providers/wiki/Android-providers

Hope it also helped :)

Use

var rootObject =  JsonConvert.DeserializeObject<RootObject>(string json);

Create your classes on JSON 2 C#

Json.NET documentation: Serializing and Deserializing JSON with Json.NET

Your second for loop should have j++ instead of i++

Use zip(*list):

>>> l = [(1,2), (3,4), (8,9)]
>>> list(zip(*l))
[(1, 3, 8), (2, 4, 9)]

The zip() function pairs up the elements from all inputs, starting with the first values, then the second, etc. By using *l you apply all tuples in l as separate arguments to the zip() function, so zip() pairs up 1 with 3 with 8 first, then 2 with 4 and 9. Those happen to correspond nicely with the columns, or the transposition of l.

zip() produces tuples; if you must have mutable list objects, just map() the tuples to lists or use a list comprehension to produce a list of lists:

map(list, zip(*l))          # keep it a generator
[list(t) for t in zip(*l)]  # consume the zip generator into a list of lists

You can use a 1 pixel per 1 pixel Java applet embedded in the page and use that for compression.

It's not JavaScript and the clients will need a Java runtime but it will do what you need.

you can use the jQuery parseJSON method:

var Data = $.parseJSON(response);

If you want to access folder you specified using Anaconda Prompt, try typing

cd C:\Users\u354590

There's a much, much easier way. Do this:

MyComponent.vue

<template>
  stuff here
</template>
<script>
  import $ from 'jquery';
  import 'selectize';

  $(function() {
      // use jquery
      $('body').css('background-color', 'orange');

      // use selectize, s jquery plugin
      $('#myselect').selectize( options go here );
  });

</script>

Make sure JQuery is installed first with npm install jquery. Do the same with your plugin.

If needing text input, the pattern works also

<input type="text" pattern="\d+">

Additionally a simpler example:

return (T)Activator.CreateInstance(typeof(T), new object[] { weight });

Note that using the new() constraint on T is only to make the compiler check for a public parameterless constructor at compile time, the actual code used to create the type is the Activator class.

You will need to ensure yourself regarding the specific constructor existing, and this kind of requirement may be a code smell (or rather something you should just try to avoid in the current version on c#).

To change the title font size, use the following example

title('mytitle','FontSize',12);

to the change the graph axes label font size, do the following

axes('FontSize',24);

What I've done to solve the same problem is to have a feature detection (I use something like this code), seeing if onTouchMove is defined, and if so I add the css class "touchMode" to the body, else i add "desktopMode".

Then every time some style effect only applies to a touch device, or only to a desktop the css rule is prepended with the appropriate class:

.desktopMode .someClass:hover{ color: red }
.touchMode .mainDiv { width: 100%; margin: 0; /*etc.*/ }

Edit: This strategy of course adds a few extra characters to your css, so If you're concerned about css size, you could search for the touchMode and desktopMode definitons and put them into different files, so you can serve optimized css for each device type; or you could change the class names to something much shorter before going to prod.

You can use for loop to find your element and update it:

updateItem(newItem){
  for (let i = 0; i < this.itemsArray.length; i++) {
      if(this.itemsArray[i].id == newItem.id){
        this.users[i] = newItem;
      }
    }
}

Another way is to use reflection:

protected T GetObject<T>(Type[] signature, object[] args)
{
    return (T)typeof(T).GetConstructor(signature).Invoke(args);
}

Taken from a related post:

public static boolean isInteger(String s) {
    try { 
        Integer.parseInt(s); 
    } catch(NumberFormatException e) { 
        return false; 
    }
    // only got here if we didn't return false
    return true;
}

To print tuple of (index, value) in list comprehension using a for loop:

ints = [8, 23, 45, 12, 78]
print [(i,ints[i]) for i in range(len(ints))]

Output:

[(0, 8), (1, 23), (2, 45), (3, 12), (4, 78)]

There is a ToArray() function on Values:

Foo[] arr = new Foo[dict.Count];    
dict.Values.CopyTo(arr, 0);

But I don't think its efficient (I haven't really tried, but I guess it copies all these values to the array). Do you really need an Array? If not, I would try to pass IEnumerable:

IEnumerable<Foo> foos = dict.Values;

Add following dependency or download Gson jar file

Follow github repo for documentation and more.

If there are multiple threads accessing class level variable then each thread can keep copy of that variable in its threadlocal cache.

Making the variable volatile will prevent threads from keeping the copy of variable in threadlocal cache.

Atomic variables are different and they allow atomic modification of their values.

OnClientClick="SomeMethod()" event of that BUTTON, it return by default "true" so after that function it do postback

for solution use

//use this code in BUTTON  ==>   OnClientClick="return SomeMethod();"

//and your function like this
<script type="text/javascript">
  function SomeMethod(){
    // put your code here 
    return false;
  }
</script>

private Point FindLocation(Control ctrl)
{
    if (ctrl.Parent is Form)
        return ctrl.Location;
    else
    {
        Point p = FindLocation(ctrl.Parent);
        p.X += ctrl.Location.X;
        p.Y += ctrl.Location.Y;
        return p;
    }
}

I had the same symptom in win7. I got this script:

<?php
    phpinfo();
    pg_connect("blah");

When I executed the phpinfo.php script via apache (http://localhost/phpinfo.php) then I got the error message: Call to undefined function pg_connect() in...

When I executed the same script from command line (php phpinfo.php) then I got the expected message: PHP Warning: pg_connect(): Unable to connect to PostgreSQL server: missing "=" after "blah"

In both cases the expected php.ini was used:

Loaded Configuration File   C:\Program Files (x86)\php\php.ini 

but the pgsql section was completely missing from the phpinfo in case of the apache-based execution and it was present in the command-line-based execution.

The solution was that I added the following line to the apache httpd.conf:

LoadFile "C:/Program Files (x86)/php/libpq.dll"

It seems that for some reason this file is not loaded automatically when apache runs the php script but it is loaded if I run the php script from the command line.

I hope it helps.

Prefixing the statement with an exclamation mark will let you know whether the array is not empty. So in your case -

a = [1,2,3]
!a.empty?
=> true

you can also user @RequestBody Map<String, String> params,then use params.get("key") to get the value of parameter

echo date('Y-m-d H:i:s.') . gettimeofday()['usec'];

output:

2016-11-19 15:12:34.346351

pip itself is just a normal python package. Thus you can install pip with pip.

Of cource, you don't want to affect the system's pip, install it inside a virtualenv.

pip install pip==1.2.1

You can use document.write or even console.write (this is good for debugging).

But your best bet and it gives you more control is to use DOM to update the page.

How can I check to see if a database in SQL Server is case-sensitive?

You can use below query that returns your informed database is case sensitive or not or is in binary sort(with null result):

;WITH collations AS (
    SELECT 
        name,
        CASE 
            WHEN description like '%case-insensitive%' THEN 0 
            WHEN description like '%case-sensitive%' THEN 1 
        END isCaseSensitive
    FROM 
        sys.fn_helpcollations()
)
SELECT *
FROM collations
WHERE name = CONVERT(varchar, DATABASEPROPERTYEX('yourDatabaseName','collation'));

For more read this MSDN information ;).

As Get-Date returns a DateTime object you are able to compare them directly. An example:

(get-date 2010-01-02) -lt (get-date 2010-01-01)

will return false.

It might be because the project has been broken down into different modules.

@SpringBootApplication
@ComponentScan({"com.delivery.request"})
@EntityScan("com.delivery.domain")
@EnableJpaRepositories("com.delivery.repository")
public class WebServiceApplication extends SpringBootServletInitializer {

First off; best practice would be to get the users Desktop folder with

string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

Then you can find all the files with something like

string[] files = Directory.GetFiles(path, "*.txt", SearchOption.AllDirectories);

Note that with the above line you will find all files with a .txt extension in the Desktop folder of the logged in user AND all subfolders.

Then you could copy or move the files by enumerating the above collection like

// For copying...
foreach (string s in files)
{
   File.Copy(s, "C:\newFolder\newFilename.txt");
}

// ... Or for moving
foreach (string s in files)
{
   File.Move(s, "C:\newFolder\newFilename.txt");
}

Please note that you will have to include the filename in your Copy() (or Move()) operation. So you would have to find a way to determine the filename of at least the extension you are dealing with and not name all the files the same like what would happen in the above example.

With that in mind you could also check out the DirectoryInfo and FileInfo classes. These work in similair ways, but you can get information about your path-/filenames, extensions, etc. more easily

What I saw above is complicate.....

Here is some code can refer to.

$("#box").on({
                mousedown:function(e)
                {
                  dragging = true;
                  dragX = e.clientX - $(this).position().left;
                  //To calculate the distance between the cursor pointer and box 
                  dragY = e.clientY - $(this).position().top;
                },
                mouseup:function(){dragging = false;},
                  //If not set this on/off,the move will continue forever
                mousemove:function(e)
                {
                  if(dragging)
                  $(this).offset({top:e.clientY-dragY,left:e.clientX-dragX});

                }
            })

dragging,dragX,dragY may place as the global variable.

It's a simple show about this issue,but there is some bug about this method.

If it's your need now,here's the Example here.
