Programs & Examples On #Viewcontroller

For reference, because this question is one of the first Google result.

Breaking change in Swift 3:

The method presentViewController is replaced by the method present.

You can use it like the old one:

self.present(viewControllerToPresent, animated: true, completion: nil)

Example to open the camera:

let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)

My navigation bar was not showing, so I have used the following method in Swift 2 iOS 9

let viewController = self.storyboard?.instantiateViewControllerWithIdentifier("Dashboard") as! Dashboard

// Creating a navigation controller with viewController at the root of the navigation stack.
let navController = UINavigationController(rootViewController: viewController)
self.presentViewController(navController, animated:true, completion: nil)

Don't create any segue from Cancel or Done to other VC and only write this code your buttons @IBAction

@IBAction func cancel(sender: AnyObject) {
    dismiss(animated: false, completion: nil)
}

As a hint: If you call present to a ViewController which is embedded inside a NavigationController you have to set the NavigationController to .fullScreen and not the VC.

You can do this like @davidbates or you do it programmatically (like @pascalbros).

The same applies to the UITabViewController

An example scenario for NavigationController:

    //BaseNavigationController: UINavigationController {}
    let baseNavigationController = storyboard!.instantiateViewController(withIdentifier: "BaseNavigationController")
    var navigationController = UINavigationController(rootViewController: baseNavigationController)
    navigationController.modalPresentationStyle = .fullScreen
    navigationController.topViewController as? LoginViewController
    self.present(navigationViewController, animated: true, completion: nil)

If you are using a navigation controller you can segue again to the current UIViewController and it will be refreshed.

Swift 5

Use Segue to perform navigation from one View Controller to another View Controller:

performSegue(withIdentifier: "idView", sender: self)

This works on Xcode 10.2.

The above code works well but if you want to navigate from an NSObject class, where you can not use self.present:

let storyBoard = UIStoryboard(name:"Main", bundle: nil)
if let conVC = storyBoard.instantiateViewController(withIdentifier: "SoundViewController") as? SoundViewController,
    let navController = UIApplication.shared.keyWindow?.rootViewController as? UINavigationController {
    
    navController.pushViewController(conVC, animated: true)
}

In a typical application there is a UITabBarController and it embeds 3 or more UIViewController as its tabs. In such a case if you subclassed a UITabBarController as YourTabBarController then you can set the selected index simply by:

selectedIndex = 1 // Displays 2nd tab. The index starts from 0.

In case you are navigating to YourTabBarController from any other view, then in that view controller's prepare(for segue:) method you can do:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destination.
        // Pass the selected object to the new view controller.
        if segue.identifier == "SegueToYourTabBarController" {
            if let destVC = segue.destination as? YourTabBarController {
                destVC.selectedIndex = 0
            }
        }

I am using this way of setting tab with Xcode 10 and Swift 4.2.

To add new ViewController once you have have an existing ViewController, follow below step:

1. Click on background of Main.storyboard.

2. Search and select ViewController from object library at the utility window.

3. Drag and drop it in background to create a new ViewController.

From MSDN:

To change security authentication mode:

In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties.

On the Security page, under Server authentication, select the new server authentication mode, and then click OK.

In the SQL Server Management Studio dialog box, click OK to acknowledge the requirement to restart SQL Server.

In Object Explorer, right-click your server, and then click Restart. If SQL Server Agent is running, it must also be restarted.

To enable the SA login:

In Object Explorer, expand Security, expand Logins, right-click SA, and then click Properties.

On the General page, you might have to create and confirm a password for the login.

On the Status page, in the Login section, click Enabled, and then click OK.

I was looking a lot to find a solution for sticy menue with old school JS (without JQuery). So I build small test to play with it. I think it can be helpfull to those looking for solution in js. It needs improvments of unsticking the menue back, and making it more smooth. Also I find a nice solution with JQuery that clones the original div instead of position fixed, its better since the rest of page element dont need to be replaced after fixing. Anyone know how to that with JS ? Please remark, correct and improve.

If you want to define a 3D matrix containing all zeros, you write

A = zeros(8,4,20);

All ones uses ones, all NaN's uses NaN, all false uses false instead of zeros.

If you have an existing 2D matrix, you can assign an element in the "3rd dimension" and the matrix is augmented to contain the new element. All other new matrix elements that have to be added to do that are set to zero.

For example

B = magic(3); %# creates a 3x3 magic square
B(2,1,2) = 1; %# and you have a 3x3x2 array

JAXBElement wrappers works for cases where no @XmlRootElement is generated by JAXB. These wrappers are available in ObjectFactory class generated by maven-jaxb2-plugin. For eg:

     public class HelloWorldEndpoint {
        @PayloadRoot(namespace = NAMESPACE_URI, localPart = "person")
        @ResponsePayload
        public JAXBElement<Greeting> sayHello(@RequestPayload JAXBElement<Person> request) {

        Person person = request.getValue();

        String greeting = "Hello " + person.getFirstName() + " " + person.getLastName() + "!";

        Greeting greet = new Greeting();
        greet.setGreeting(greeting);

        ObjectFactory factory = new ObjectFactory();
        JAXBElement<Greeting> response = factory.createGreeting(greet);
        return response;
      }
 }

For me, it was permission issue. Docker run is called with a user profile but root is the user inside the container. The solution was to make curl write to /tmp since that has write permission for all users , not just root.

I used the -o option.

-o /tmp/file_to_download

I know this may be a bit old, but try using PDO::lastInsertId. I think it does what you want it to, but you would have to rewrite your application to use PDO (Which is a lot safer against attacks)

COPY table_name FROM 'path/to/data.csv' DELIMITER ',' CSV HEADER;

Change the value after the page loads

$('#data').val('').change();

My code is super easy and works for any order of matrix

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    System.out.println(" Enter No. of rows in matrix 1 : ");
    int arows = sc.nextInt();
    System.out.println(" Enter No. of columns in matrix 1 : ");
    int acols = sc.nextInt();
    System.out.println(" Enter No. of rows in matrix 2 : ");
    int brows = sc.nextInt();
    System.out.println(" Enter No. of columns in matrix 2 : ");
    int bcols = sc.nextInt();
    if (acols == brows) {
        System.out.println(" Enter elements of matrix 1 ");
        int a[][] = new int[arows][acols];
        int b[][] = new int[brows][bcols];
        for (int i = 0; i < arows; i++) {
            for (int j = 0; j < acols; j++) {
                a[i][j] = sc.nextInt();

We put together Web Services on Windows Server and were trying to connect with PHP on Apache. We got the same error. The issue ended up being different versions of the Soap client on the different servers. Matching the SOAP versions in the options on both servers solved the issue in our case.

Yes, I would use explode or you could use:

preg_split

Which is the advised method with PHP 6. preg_split Documentation

You need to give some force

Just do push --force.

Yes, you can find out element by data attribute.

element = $('a[data-item-id="stand-out"]');

As of Git v2.23.0 (August 2019), git switch is preferred over git checkout when you’re simply switching branches/tags. I’m guessing they did this since git checkout had two functions: for switching branches and for restoring files. So in v2.23.0, they added two new commands, git switch, and git restore, to separate those concerns. I would predict at some point in the future, git checkout will be deprecated.

To switch to a normal branch, use git switch <branch-name>. To switch to a commit-like object, including single commits and tags, use git switch --detach <commitish>, where <commitish> is the tag name or commit number.

The --detach option forces you to recognize that you’re in a mode of “inspection and discardable experiments”. To create a new branch from the commitish you’re switching to, use git switch -c <new-branch> <start-point>.

Note: this answer is deprecated. see other answers if you are using Django 1.7 or later.

This is how I do it.

#in models.py
from django.contrib.auth.models import User
from django.db.models.signals import post_save

class UserProfile(models.Model):  
    user = models.OneToOneField(User)  
    #other fields here

    def __str__(self):  
          return "%s's profile" % self.user  

def create_user_profile(sender, instance, created, **kwargs):  
    if created:  
       profile, created = UserProfile.objects.get_or_create(user=instance)  

post_save.connect(create_user_profile, sender=User) 

#in settings.py
AUTH_PROFILE_MODULE = 'YOURAPP.UserProfile'

This will create a userprofile each time a user is saved if it is created. You can then use

  user.get_profile().whatever

Here is some more info from the docs

http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users

Update: Please note that AUTH_PROFILE_MODULE is deprecated since v1.5: https://docs.djangoproject.com/en/1.5/ref/settings/#auth-profile-module

I had the same problem after updating IntelliJ IDE, the fix was: delete existed plugin lombok and install it again (the newest version),

Issue: "PUSH Failed refs/head/ - pre-receive hook declined"

I've faced the problem of unable to push my changes to my origin branch and anything to master branch of a particular project repository as the size of that repo was over hard limit of 2GB. It was throwing the error. That's because we had pushed the test data unknowingly to bitbucket from other testing branches.

PUSH Failed refs/head/ - pre-receive hook declined

So tried checking is that the same with other project repo's and they weren't having any issues.

Fix:

My colleague noticed that when we cloned the project back locally, the size of the project was 110MB. So then we started cleaning the branches we merged earlier and active branches which are no more required. Once that cleaning is done for couple of branches we realized the size of the repo went drastically down from 2GB to 120MB. Then we tried to push the changes to my branch and it worked.

Shift+F5 quickly clears the cache.

Note: if you limit that log to the last n commit (last 3 commits for instance, git log -3), make sure to put a space between 'n' and your branch:

git log -3 master..

Before Git 2.1 (August 2014), this mistake: git log -3master.. would actually show you the last 3 commits of the current branch (here my_experiment), ignoring the master limit (meaning if my_experiment contains only one commit, 3 would still be listed, 2 of them from master)

See commit e3fa568 by Junio C Hamano (gitster):

revision: parse "git log -<count>" more carefully

This mistyped command line simply ignores "master" and ends up showing two commits from the current HEAD:

$ git log -2master

because we feed "2master" to atoi() without making sure that the whole string is parsed as an integer.

Use the strtol_i() helper function instead.

Try out this one liner arrow function

Object.values(o).map(a => a.value, o).reduce((ac, key, index, arr) => ac+=key)

Yes. You need to use the try/catch block, but no need to catch the Exception. As per the API it will throw NoResultException if there is no result, and its up to you how you want to handle it.

DrawUnusedBalance drawUnusedBalance = null;
try{
drawUnusedBalance = (DrawUnusedBalance)query.getSingleResult()
catch (NoResultException nre){
//Ignore this because as per your logic this is ok!
}

if(drawUnusedBalance == null){
 //Do your logic..
}

There are several ways to iterate a map. Please refer to the following code.

When you iterate a map using iterator Interface you must go with Entry<K,V> or entrySet().

It looks like this:

    import java.util.*;
    import java.util.HashMap;
    import java.util.Iterator;
    import java.util.Map;

    public class IteratMapDemo{

        public static void main(String arg[]){
            Map<String, String> mapOne = new HashMap<String, String>();
            mapOne.put("1", "January");
            mapOne.put("2", "February");
            mapOne.put("3", "March");
            mapOne.put("4", "April");
            mapOne.put("5", "May");
            mapOne.put("6", "June");
            mapOne.put("7", "July");
            mapOne.put("8", "August");
            mapOne.put("9", "September");
            mapOne.put("10", "Octomber");
            mapOne.put("11", "November");
            mapOne.put("12", "December");

            Iterator it = mapOne.entrySet().iterator();
            while(it.hasNext())
            {
                Map.Entry me = (Map.Entry) it.next();
                //System.out.println("Get Key through While loop = " + me.getKey());
            }
            for(Map.Entry<String, String> entry:mapOne.entrySet()){
                //System.out.println(entry.getKey() + "=" + entry.getValue());
            }

            for (Object key : mapOne.keySet()) {
                System.out.println("Key: " + key.toString() + " Value: " +
                                   mapOne.get(key));
            }
        }
    }

print "Number of lines: $nids\n";
print "Content: $ids\n";

How did Perl complain? print $ids should work, though you probably want a newline at the end, either explicitly with print as above or implicitly by using say or -l/$\.

If you want to interpolate a variable in a string and have something immediately after it that would looks like part of the variable but isn't, enclose the variable name in {}:

print "foo${ids}bar";

Here is a code snippet taken from a blog article written by Anubhav Goyal:

// this code will mark the forms authentication cookie and the
// session cookie as Secure.
if (Response.Cookies.Count > 0)
{
    foreach (string s in Response.Cookies.AllKeys)
    {
        if (s == FormsAuthentication.FormsCookieName || "asp.net_sessionid".Equals(s, StringComparison.InvariantCultureIgnoreCase))
        {
             Response.Cookies[s].Secure = true;
        }
    }
}

Adding this to the EndRequest event handler in the global.asax should make this happen for all page calls.

Note: An edit was proposed to add a break; statement inside a successful "secure" assignment. I've rejected this edit based on the idea that it would only allow 1 of the cookies to be forced to secure and the second would be ignored. It is not inconceivable to add a counter or some other metric to determine that both have been secured and to break at that point.

Install virtual env with

virtualenv --system-site-packages

and use pip install -U to install matplotlib

This solution works well, I tested on my phone:

document.body.ontouchend = function() { document.querySelector('[name="name"]').focus(); };

enjoy

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

You can use map function and pythons inbuilt sum() function. It simplifies the solution. And reduces the complexity.
a=map(int,raw_input().split())
sum(a)
Done!

Faced the same issue. To solve it,

• I had to download and install the latest version of gradle using the comand line. $ sdk install gradle using the package manager or $ brew install gradle for mac. You might need to first install brew if not yet.
• Then I cleaned the project and restarted android studio and it worked.

_ Alias for gettext()

The underscore character '_' as in _() is an alias to the gettext() function.

Use nnz instead of sum. No need for the double call to collapse matrices to vectors and it is likely faster than sum.

nnz(your_matrix == 5)

Yes, you can delete data from iOS device support by the symbols of the operating system, one for each version for each architecture. It's used for debugging. If you don't need to support those devices any more, you can delete the directory without ill effect

I had a similar issue recently while working on recursion and nested lists. I declared:

print(r_sum([1,2,3[1,2,3],]))

instead of

print(r_sum([1,2,3,[1,2,3],]))

browser's back/forward button solution
I encountered the same problem and I solved it using the popstate event from the $window object and ui-router's $state object. A popstate event is dispatched to the window every time the active history entry changes.
The $stateChangeSuccess and $locationChangeSuccess events are not triggered on browser's button click even though the address bar indicates the new location.
So, assuming you've navigated from states main to folder to main again, when you hit back on the browser, you should be back to the folder route. The path is updated but the view is not and still displays whatever you have on main. try this:

angular
.module 'app', ['ui.router']
.run($state, $window) {

     $window.onpopstate = function(event) {

        var stateName = $state.current.name,
            pathname = $window.location.pathname.split('/')[1],
            routeParams = {};  // i.e.- $state.params

        console.log($state.current.name, pathname); // 'main', 'folder'

        if ($state.current.name.indexOf(pathname) === -1) {
            // Optionally set option.notify to false if you don't want 
            // to retrigger another $stateChangeStart event
            $state.go(
              $state.current.name, 
              routeParams,
              {reload:true, notify: false}
            );
        }
    };
}

back/forward buttons should work smoothly after that.

note: check browser compatibility for window.onpopstate() to be sure

I just created a project which explain what is the difference between all subjects:
https://github.com/piecioshka/rxjs-subject-vs-behavior-vs-replay-vs-async

I just had the same issue on an application that is loading a script with a relative path.

It appeared the script was simply blocked by Adblock Plus.

Try to disable your ad/script blocker (Adblock, uBlock Origin, Privacy Badger…) or relocate the script such that it does not match your ad blocker's rules.

If you don't have such a plugin installed, try to reproduce the issue while running Firefox in safe mode.

• If you cannot reproduce it in safe mode, it means your issue is linked to one of your plugins or settings.
• Otherwise, it might be a different issue. Make sure you have the same error message as in the question. Also look at the network tab of the developer tools to check if your script is listed (reload the page first if needed).

Similar to colMeans, colSums, etc, you could write a column maximum function, colMax, and a column sort function, colSort.

colMax <- function(data) sapply(data, max, na.rm = TRUE)
colSort <- function(data, ...) sapply(data, sort, ...)

I use ... in the second function in hopes of sparking your intrigue.

Get your data:

dat <- read.table(h=T, text = "Ozone Solar.R Wind Temp Month Day
1     41     190  7.4   67     5   1
2     36     118  8.0   72     5   2
3     12     149 12.6   74     5   3
4     18     313 11.5   62     5   4
5     NA      NA 14.3   56     5   5
6     28      NA 14.9   66     5   6
7     23     299  8.6   65     5   7
8     19      99 13.8   59     5   8
9      8      19 20.1   61     5   9")

Use colMax function on sample data:

colMax(dat)
#  Ozone Solar.R    Wind    Temp   Month     Day 
#   41.0   313.0    20.1    74.0     5.0     9.0

To do the sorting on a single column,

sort(dat$Solar.R, decreasing = TRUE)
# [1] 313 299 190 149 118  99  19

and over all columns use our colSort function,

colSort(dat, decreasing = TRUE) ## compare with '...' above

If you want vertical spacing between elements, use a margin.

Don't add extra elements if you don't need to.

For those of you who share my weird fondness of manually editing config files, adding (or modifying) the following would also do the trick.

.git/config (personal config)

[submodule "cookbooks/apt"]
    url = https://github.com/opscode-cookbooks/apt

.gitmodules (committed shared config)

[submodule "cookbooks/apt"]
    path = cookbooks/apt
    url = https://github.com/opscode-cookbooks/apt

See this as well - difference between .gitmodules and specifying submodules in .git/config?

  StackTrace stackTrace = new StackTrace();           // get call stack
  StackFrame[] stackFrames = stackTrace.GetFrames();  // get method calls (frames)

    Console.WriteLine(stackFrame.GetMethod().Name);   // write method name

So, if you'll take the first one - you know what function you are in. If you're creating a helper tracing function - take one before the last one - you'll know your caller.

From a technical point of view they're completely different. <datalist> is an abstract container of options for other elements. In your case you've used it with <input type="text" but you can also use it with ranges, colors, dates etc. http://demo.agektmr.com/datalist/

If using it with text input, as a type of autocomplete, then the question really is: Is it better to use a free-form text input, or a predetermined list of options? In that case I think the answer is a bit more obvious.

If we focus on the use of <datalist> as a list of options for a text field then here are some specific differences between that and a select box:

• A <datalist> fed text box has a single string for both display label and submit. A select box can have a different submit value vs. display label <option value='ie'>Internet Explorer</option>.
• A <datalist> fed text box does not support the <optgroup> tag to organize the display.
• You can not restrict a user to the list of options in a <datalist> like you can with a <select>.
• The onchange event works differently. On a <select> element, the onchange event is fired immediately upon change, whereas with <input type="text" the event is fired after the element loses focus or the user presses enter.
• <datalist> has really spotty support across browsers. The way to show all available options is inconsistent, and things only get worse from there.

The last point is really the big one in my opinion. Since you will HAVE to have a more universal autocomplete fallback, then there is almost no reason to go through the trouble of configuring a <datalist>. Plus any decent autocomplete pluging will allow for ways to style the display of your options, which <datalist> does not do. If <datalist> accepted <li> elements that you could manipulate however you want, it would have been really great! But NO.

Also insofar as i can tell, the <datalist> search is an exact match from the beginning of the string. So if you had <option value="internet explorer"> and you searched for 'explorer' you would get no results. Most autocomplete plugins will search anywhere in the text.

I've only used <datalist> as a quick and lazy convenience helper for some internal pages where I know with a 100% certainty that the users have the latest Chrome or Firefox, and will not try to submit bogus values. For any other case, it's hard to recommend the use of <datalist> due to very poor browser support.

If the map holds a collection as value, the other answers require additional effort to convert them as strings, such as Arrays.deepToString(value.toArray()) (if its a map of list values), etc.

I faced these issues quite often and came across the generic function to print all objects using ObjectMappers. This is quite handy at all the places, especially during experimenting things, and I would recommend you to choose this way.

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;

public static String convertObjectAsString(Object object) {
    String s = "";
    ObjectMapper om = new ObjectMapper();
    try {
        om.enable(SerializationFeature.INDENT_OUTPUT);
        s = om.writeValueAsString(object);
    } catch (Exception e) {
        log.error("error converting object to string - " + e);
    }
    return s;
}

use

SELECT COUNT(DISTINCT productId) from  table_name WHERE keyword='$keyword'

Make sure your root index.php file has the correct permission, its permission must be 0755 or 0644

IISReset stops and restarts the entire web server (including non-ASP.NET apps)
Recycling an app pool will only affect applications running in that app pool.
Editing the web.config in a web application only affects that web application (recycles just that app).
Editing the machine.config on the machine will recycle all app pools running.

IIS will monitor the /bin directory of your application. Whenever a change is detected in those dlls, it will recycle the app and re-load those new dlls. It also monitors the web.config & machine.config in the same way and performs the same action for the applicable apps.

I know, this problem can be faced by so many people and many of them have uninstalled and re-installed the sql server for resolving this issue. In my observation the problem of not connecting the database service locally is just because of your network connection you are using, in most of the cases these problems will come when you are using wi-fi network.

Solution is, if you are using wi-fi then just right click on status of the network and get the ip details and enter the same ip in sql server name, it will work. Regards Vishwajeet

Setattr: We use setattr to add an attribute to our class instance. We pass the class instance, the attribute name, and the value. and with getattr we retrive these values

For example

Employee = type("Employee", (object,), dict())

employee = Employee()

# Set salary to 1000
setattr(employee,"salary", 1000 )

# Get the Salary
value = getattr(employee, "salary")

print(value)

CTRL+R, CTRL+W : Toggle showing whitespace

or under the Edit Menu:

• Edit -> Advanced -> View White Space

[BTW, it also appears you are using Tabs. It's common practice to have the IDE turn Tabs into spaces (often 4), via Options.]

In Xcode 10.1 the solution for me was to change the build system on Workspace Settings in the File menu. It is by default set to New Build System, changed that to Legacy Build System and that did the trick.

Simplest Solution

Code:

import pandas as pd
pd.__version__

**Its double underscore before and after the word "version".

Output:

'0.14.1'

If you specify the disabled attribute then the value you give it must be disabled. (In HTML 5 you may leave off everything except the attribute value. In HTML 4 you may leave off everything except the attribute name.)

If you do not want the control to be disabled then do not specify the attribute at all.

Disabled:

<input type="checkbox" disabled>
<input type="checkbox" disabled="disabled">

Enabled:

<input type="checkbox">

Invalid (but usually error recovered to be treated as disabled):

<input type="checkbox" disabled="1">
<input type="checkbox" disabled="true">
<input type="checkbox" disabled="false">

So, without knowing your template language, I guess you are looking for:

<td><input type="checkbox" name="repriseCheckBox" {checkStat == 1 ? disabled : }/></td>

If you are looking for a more generalized way to apply to many columns, what you can do is to build a list of column names and pass it as the index of the grouped dataframe. In your case, for example:

columns = ['Y'+str(i) for year in range(1967, 2011)]

df.groupby('Country')[columns].agg('sum')

"On Mac OS, run Android Studio with Java Runtime Environment (JRE) 6 for optimized font rendering. You can then configure your project to use Java Development Kit (JDK) 6 or JDK 7."

This was listed in http://developer.android.com/sdk/index.html under the system requirements for Mac OS X.

Once you install Java 6 (not the JDK) from Apple as per Alonso C. Licks, you should be able to open Android Studio and reconfigure as you wish without having to mess around in the terminal, info.plist file, or other libraries.

I think you could use TIMESTAMPDIFF(unit,datetime_expr1,datetime_expr2) something like

select * from MyTab T where
TIMESTAMPDIFF(MINUTE,T.runTime,NOW()) > 20

If you are trying to upload an array of files then you may need to increase max_file_uploads in php.ini which is by default set to 20

Note: max_file_uploads can NOT be changed outside php.ini. See PHP "Bug" #50684

You shold use the keys() or names() method. keys() will give you an iterator containing all the String property names in the object while names() will give you an array of all key String names.

You can get the JSONObject documentation here

http://developer.android.com/reference/org/json/JSONObject.html

Is there a reason you're using Nullable?

If you want to use Nullable then you can write variable.Value.TotalHours.

Or you can just write: (datevalue1 - datevalue2).TotalHours.

You can't call something on the entire viewModel, but on an individual observable you can call myObservable.valueHasMutated() to notify subscribers that they should re-evaluate. This is generally not necessary in KO, as you mentioned.

Thought this might be helpful to some who are using Javascript and/or Typescript in 2019.

I found the following, as some have suggested, to be incorrect:

let img = new Image();
img.onload = function() {
  console.log(this.width, this.height) // Error: undefined is not an object
};
img.src = "http://example.com/myimage.jpg";

This is correct:

let img = new Image();
img.onload = function() {
  console.log(img.width, img.height)
};
img.src = "http://example.com/myimage.jpg";

Conclusion:

Use img, not this, in onload function.

This is a great article for syntax needed to create new objects from a LINQ query.

But, if the assignments to fill in the fields of the object are anything more than simple assignments, for example, parsing strings to integers, and one of them fails, it is not possible to debug this. You can not create a breakpoint on any of the individual assignments.

And if you move all the assignments to a subroutine, and return a new object from there, and attempt to set a breakpoint in that routine, you can set a breakpoint in that routine, but the breakpoint will never be triggered.

So instead of:

var query2 = from c in doc.Descendants("SuggestionItem")
                select new SuggestionItem
                       { Phrase = c.Element("Phrase").Value
                         Blocked = bool.Parse(c.Element("Blocked").Value),
                         SeenCount = int.Parse(c.Element("SeenCount").Value)
                       };

Or

var query2 = from c in doc.Descendants("SuggestionItem")
                         select new SuggestionItem(c);

I instead did this:

List<SuggestionItem> retList = new List<SuggestionItem>();

var query = from c in doc.Descendants("SuggestionItem") select c;

foreach (XElement item in query)
{
    SuggestionItem anItem = new SuggestionItem(item);
    retList.Add(anItem);
}

This allowed me to easily debug and figure out which assignment was failing. In this case, the XElement was missing a field I was parsing for to set in the SuggestionItem.

I ran into these gotchas with Visual Studio 2017 while writing unit tests for a new library routine.

class Foo          (object):
    # ^class name  #^ inherits from object

    bar = "Bar" #Class attribute.

    def __init__(self):
        #        #^ The first variable is the class instance in methods.  
        #        #  This is called "self" by convention, but could be any name you want.
        #^ double underscore (dunder) methods are usually special.  This one 
        #  gets called immediately after a new instance is created.

        self.variable = "Foo" #instance attribute.
        print self.variable, self.bar  #<---self.bar references class attribute
        self.bar = " Bar is now Baz"   #<---self.bar is now an instance attribute
        print self.variable, self.bar  

    def method(self, arg1, arg2):
        #This method has arguments.  You would call it like this:  instance.method(1, 2)
        print "in method (args):", arg1, arg2
        print "in method (attributes):", self.variable, self.bar


a = Foo() # this calls __init__ (indirectly), output:
                 # Foo bar
                 # Foo  Bar is now Baz
print a.variable # Foo
a.variable = "bar"
a.method(1, 2) # output:
               # in method (args): 1 2
               # in method (attributes): bar  Bar is now Baz
Foo.method(a, 1, 2) #<--- Same as a.method(1, 2).  This makes it a little more explicit what the argument "self" actually is.

class Bar(object):
    def __init__(self, arg):
        self.arg = arg
        self.Foo = Foo()

b = Bar(a)
b.arg.variable = "something"
print a.variable # something
print b.Foo.variable # Foo

Goto the project repo, right click -> 'Git Bash Here'

In the git bash windows type

cd ~
pwd

i get something like this

/c/Users/<windows_username>

Now copy your public and private keys to this path

C:\Users\<windows_username>\.ssh

i got the below files there

id_rsa
id_rsa.pub
known_hosts

here

Now when ever it needs to use the credentials it uses these files and prompt for password if needed.

private void button1_Click(object sender, EventArgs e)
{
        Form2 frm2 = new Form2(textBox1.Text);
        frm2.Show();

        textBox1.Text = qs;

    }

Be sure to fully qualify your sheets with which workbook they are referencing!

 mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name

Changing my header to the following solve the problem:

<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

First, you should make sure that document.getElementsByName("username")[0] actually returns an object and not "undefined". You can simply check like

if (typeof document.getElementsByName("username")[0] != 'undefined')

Similarly for the other element password.

You need a reference to an Axes object to keep drawing on the same subplot.

import matplotlib.pyplot as plt

x = range(100)
y = range(100,200)
fig = plt.figure()
ax1 = fig.add_subplot(111)

ax1.scatter(x[:4], y[:4], s=10, c='b', marker="s", label='first')
ax1.scatter(x[40:],y[40:], s=10, c='r', marker="o", label='second')
plt.legend(loc='upper left');
plt.show()

I had this error occur for a different reason.

I created a template for save/cancel buttons that I wanted to appear at top and bottom of the page. It worked at first when I had my template defined inside of a <script type="text/html"> element.... but then I heard you could optionally create a template out of an ordinary DIV element instead.

(This worked better for me since I was using ASP.NET MVC and none of my @variableName Razor syntax was being executed at runtime from inside of the script element. So by changing to a DIV instead, I could still have the MVC Razor engine generate HTML inside my KnockoutJs template when the page loads.)

After I changed my template to use a DIV instead of a SCRIPT element, my code looked like this.... which worked fine on IE10. However, later when I tested it on IE8, it threw that....

"You cannot apply bindings multiple times to the same element" error.....

HTML

<div id="mainKnockoutDiv" class="measurementsDivContents hourlyMeasurements">

  <div id="saveButtons_template" style="display: none;">
    ... my template content here ...
  </div>

  <!--ko template: { name: 'saveButtons_template' } -->
  <!--/ko-->

  Some_HTML_content_here....

  <!--ko template: { name: 'saveButtons_template' } -->
  <!--/ko-->

</div>

JavaScript

ko.applyBindings(viewModel, document.getElementById('mainKnockoutDiv'));

THE SOLUTION:

All I had to do was move my saveButtons_template DIV down to the bottom, so that it was outside of the mainKnockoutDiv. This solved the problem for me.

I suppose KnockoutJs was trying to bind my template DIV multiple times since it was located inside the applyBindings target area... and was not using the SCRIPT element.... and was being referenced as a template.

This is not a bug- you can only transition on ordinal/calculable properties (an easy way of thinking of this is any property with a numeric start and end number value..though there are a few exceptions).

This is because transitions work by calculating keyframes between two values, and producing an animation by extrapolating intermediate amounts.

visibility in this case is a binary setting (visible/hidden), so once the transition duration elapses, the property simply switches state, you see this as a delay- but it can actually be seen as the final keyframe of the transition animation, with the intermediary keyframes not having been calculated (what constitutes the values between hidden/visible? Opacity? Dimension? As it is not explicit, they are not calculated).

opacity is a value setting (0-1), so keyframes can be calculated across the duration provided.

A list of transitionable (animatable) properties can be found here

The id that got generated for your drop down control in the html will be dynamic one. So use the complete id $('ct100_<Your control id>').val(). It will work.

Not the best, but whether it is practical method:

Use HijackThis.

Run hijack this, click the "Open the Misc Tools section" button

click "Open Uninstall Manager"

click save list (*.txt), yes to the prompts, notepad will open with your add/remove programs list.

Applications -> XAMPP -> htdocs This is the place where you should put your files for the website you're building.

If you know the number of levels in nested arrays you can simply do nested loops. Like so:

//  Scan through outer loop
foreach ($tmpArray as $innerArray) {
    //  Check type
    if (is_array($innerArray)){
        //  Scan through inner loop
        foreach ($innerArray as $value) {
            echo $value;
        }
    }else{
        // one, two, three
        echo $innerArray;
    }
}

if you do not know the depth of array you need to use recursion. See example below:

//  Multi-dementional Source Array
$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(
            7,
            8,
            array("four", 9, 10)
    ))
);

//  Output array
displayArrayRecursively($tmpArray);

/**
 * Recursive function to display members of array with indentation
 *
 * @param array $arr Array to process
 * @param string $indent indentation string
 */
function displayArrayRecursively($arr, $indent='') {
    if ($arr) {
        foreach ($arr as $value) {
            if (is_array($value)) {
                //
                displayArrayRecursively($value, $indent . '--');
            } else {
                //  Output
                echo "$indent $value \n";
            }
        }
    }
}

The code below with display only nested array with values for your specific case (3rd level only)

$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(7, 8, 9))
);

//  Scan through outer loop
foreach ($tmpArray as $inner) {

    //  Check type
    if (is_array($inner)) {
        //  Scan through inner loop
        foreach ($inner[1] as $value) {
           echo "$value \n";
        }
    }
}

Distinct and the aggregation framework are not inter-operable.

Instead you just want:

db.zips.aggregate([ 
    {$group:{_id:{city:'$city', state:'$state'}, numberOfzipcodes:{$sum:1}}}, 
    {$sort:{numberOfzipcodes:-1}},
    {$group:{_id:'$_id.state', city:{$first:'$_id.city'}, 
              numberOfzipcode:{$first:'$numberOfzipcodes'}}}
]);

It means the CPU attempted to execute an instruction it didn't understand. This could be caused by corruption I guess, or maybe it's been compiled for the wrong architecture (in which case I would have thought the O/S would refuse to run the executable). Not entirely sure what the root issue is.

Using of WildcardPattern from System.Management.Automation may be an option.

pattern = new WildcardPattern(patternString);
pattern.IsMatch(stringToMatch);

Visual Studio UI may not allow you to add System.Management.Automation assembly to References of your project. Feel free to add it manually, as described here.

Here what I DO on MY PC I install all software that i usually used in G: partian not C: if my operating system is fall (win 10) , Do not need to reinstall them again and lost time , Then How windows work it update PATH automatic if you install any new programe or pice of softwore ,

SO

I must update PATH like these HERE! all my software i usually used 1- I created folder called Programe Files 2- I install all my programe data in these folder 3-and then going to PATH and add it Dont forget ;

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;G:\HashiCorp\Vagrant\bin;G:\xampp\php;G:\xampp\mysql\bin;G:\Program Files (x86)\heroku\bin;G:\Program Files (x86)\Git\bin;G:\Program Files (x86)\composer;G:\Program Files (x86)\nodejs;G:\Program Files (x86)\Sublime Text 3;G:\Program Files (x86)\Microsoft VS Code\bin;G:\Program Files (x86)\cygwin64\bin

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

Pelo Hyper-V:

private PerformanceCounter theMemCounter = new PerformanceCounter(
    "Hyper-v Dynamic Memory VM",
    "Physical Memory",
    Process.GetCurrentProcess().ProcessName); 

Use the START command:

start [programPath]

If the path to the program contains spaces remember to add quotes. In this case you also need to provide a title for the opening console window

start "[title]" "[program path]"

If you need to provide arguments append them at the end (outside the command quotes)

start "[title]" "[program path]" [list of command args]

Use the /b option to avoid opening a new console window (but in that case you cannot interrupt the application using CTRL-C

Brief code but full-featured

The following is a hybrid jQuery solution that formats each data "record" into an HTML element and uses the data's properties as HTML attribute values.

The jquery each runs the inner loop; I needed the regular JavaScript for on the outer loop to be able to grab the property name (instead of value) for display as the heading. According to taste it can be modified for slightly different behaviour.

This is only 5 main lines of code but wrapped onto multiple lines for display:

$.get("data.php", function(data){

    for (var propTitle in data) {

        $('<div></div>') 
            .addClass('heading')
            .insertBefore('#contentHere')
            .text(propTitle);

            $(data[propTitle]).each(function(iRec, oRec) {

                $('<div></div>')
                    .addClass(oRec.textType)
                    .attr('id', 'T'+oRec.textId)
                    .insertBefore('#contentHere')
                    .text(oRec.text);
            });
    }

});

Produces the output

(Note: I modified the JSON data text values by prepending a number to ensure I was displaying the proper records in the proper sequence - while "debugging")

<div class="heading">
    justIn
</div>
<div id="T123" class="Greeting">
    1Hello

Apply a style sheet

<style>
.heading { font-size: 24px; text-decoration:underline }
.Greeting { color: green; }
.Question { color: blue; }
.Order { color: red; }
</style>

to get a "beautiful" looking set of data

More Info
The JSON data was used in the following way:

for each category (key name the array is held under):

• the key name is used as the section heading (e.g. justIn)

for each object held inside an array:

• 'text' becomes the content of a div
• 'textType' becomes the class of the div (hooked into a style sheet)
• 'textId' becomes the id of the div
• e.g. <div id="T122" class="Order">Come over here</div>

pip install --user <package name> (no sudo needed) worked for me for a very similar problem.

Try this:

$(someElem).html('this<br> has<br> newlines);

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

String hexToAscii(String s) {
  int n = s.length();
  StringBuilder sb = new StringBuilder(n / 2);
  for (int i = 0; i < n; i += 2) {
    char a = s.charAt(i);
    char b = s.charAt(i + 1);
    sb.append((char) ((hexToInt(a) << 4) | hexToInt(b)));
  }
  return sb.toString();
}

private static int hexToInt(char ch) {
  if ('a' <= ch && ch <= 'f') { return ch - 'a' + 10; }
  if ('A' <= ch && ch <= 'F') { return ch - 'A' + 10; }
  if ('0' <= ch && ch <= '9') { return ch - '0'; }
  throw new IllegalArgumentException(String.valueOf(ch));
}

You comment:

valeur is a vector equal to [ 0. 1. 2. 3.] I am interested in each single term. For the part below 0.6, then return "this works"....

If you are interested in each term, then write the code so it deals with each. For example.

for b in valeur<=0.6:
    if b:
        print ("this works")
    else:   
        print ("valeur is too high")

This will write 2 lines.

The error is produced by numpy code when you try to use it a context that expects a single, scalar, value. if b:... can only do one thing. It does not, by itself, iterate through the elements of b doing a different thing for each.

You could also cast that iteration as list comprehension, e.g.

['yes' if b else 'no' for b in np.array([True, False, True])]

The solutions above are great for interactive use, where you can eyeball the result and weed out false positives that way.

False positives can occur if the executable itself happens to match, or any arguments that are not script names match - the likelihood is greater with scripts that have no filename extensions.

Here's a more robust solution for scripting, using a shell function:

getscript() {
  pgrep -lf ".[ /]$1( |\$)"
}

Example use:

# List instance(s) of script "aa.sh" that are running.
getscript "aa.sh"  # -> (e.g.): 96112 bash /Users/jdoe/aa.sh

# Use in a test:
if getscript "aa.sh" >/dev/null; then
  echo RUNNING
fi

• Matching is case-sensitive (on macOS, you could add -i to the pgrep call to make it case-insensitive; on Linux, that is not an option.)
• The getscript function also works with full or partial paths that include the filename component; partial paths must not start with / and each component specified must be complete. The "fuller" the path specified, the lower the risk of false positives. Caveat: path matching will only work if the script was invoked with a path - this is generally true for scripts in the $PATH that are invoked directly.
• Even this function cannot rule out all false positives, as paths can have embedded spaces, yet neither ps nor pgrep reflect the original quoting applied to the command line. All the function guarantees is that any match is not the first token (which is the interpreter), and that it occurs as a separate word, optionally preceded by a path.
• Another approach to minimizing the risk of false positives could be to match the executable name (i.e., interpreter, such as bash) as well - assuming it is known; e.g.

# List instance(s) of a running *bash* script.
getbashscript() {
  pgrep -lf "(^|/)bash( | .*/)$1( |\$)"
}

If you're willing to make further assumptions - such as script-interpreter paths never containing embedded spaces - the regexes could be made more restrictive and thus further reduce the risk of false positives.

I used Retrofit 2.0 for my register users, send multipart/form File image and text from register account

In my RegisterActivity, use an AsyncTask

//AsyncTask
private class Register extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {..}

    @Override
    protected String doInBackground(String... params) {
        new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
        responseMensaje = StaticValues.mensaje ;
        mensajeCodigo = StaticValues.mensajeCodigo;
        return String.valueOf(StaticValues.code);
    }

    @Override
    protected void onPostExecute(String codeResult) {..}

And in my Register.java class is where use Retrofit with synchronous call

Based on another Stack Overflow answer, Most lightweight way to create a random string and a random hexadecimal number, a better version than the accepted answer would be:

('%06x' % random.randrange(16**6)).upper()

much faster.

This line will unconditionally restart the running program from scratch:

os.execl(sys.executable, sys.executable, *sys.argv)

One of its advantage compared to the remaining suggestions so far is that the program itself will be read again.

This can be useful if, for example, you are modifying its code in another window.

In Swift you can use the following code:

extension YourViewController: UIWebViewDelegate {
    func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebView.NavigationType) -> Bool {
        if let url = request.url, navigationType == UIWebView.NavigationType.linkClicked {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
            return false
        }
        return true
    }

}

Make sure you check for the URL value and the navigationType.

More information needed for a definitive answer, but this code

myNodeList = (ArrayList<MyNode>)this.getVertices();

will only work if this.getVertices() returns a (subtype of) List<MyNode>. If it is a different collection (like your Exception seems to indicate), you want to use

new ArrayList<MyNode>(this.getVertices())

This will work as long as a Collection type is returned by getVertices.

Constant initializer allowed by C++ Standard only for integral or enumeration types. See 9.4.2/4 for details:

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a name- space scope if it is used in the program and the namespace scope definition shall not contain an initializer.

And 9.4.2/7:

Static data members are initialized and destroyed exactly like non-local objects (3.6.2, 3.6.3).

So you should write somewhere in cpp file:

const char* SomeClass::SOMETHING = "sommething";

I was getting this from webpack lazy loading like this

import Loader from 'some-loader-component';
const WishlistPageComponent = loadable(() => import(/* webpackChunkName: 'WishlistPage' */'../components/WishlistView/WishlistPage'), {
  fallback: Loader, // warning
});
render() {
    return <WishlistPageComponent />;
}


// changed to this then it's suddenly fine
const WishlistPageComponent = loadable(() => import(/* webpackChunkName: 'WishlistPage' */'../components/WishlistView/WishlistPage'), {
  fallback: '', // all good
});    

In case you don't need to convert zero values, I find the methods to_i and to_f to be extremely useful since they will convert the string to either a zero value (if not convertible or zero) or the actual Integer or Float value.

"0014.56".to_i # => 14
"0014.56".to_f # => 14.56
"0.0".to_f # => 0.0
"not_an_int".to_f # 0
"not_a_float".to_f # 0.0

"0014.56".to_f ? "I'm a float" : "I'm not a float or the 0.0 float" 
# => I'm a float
"not a float" ? "I'm a float" : "I'm not a float or the 0.0 float" 
# => "I'm not a float or the 0.0 float"

EDIT2 : be careful, the 0 integer value is not falsey it's truthy (!!0 #=> true) (thanks @prettycoder)

EDIT

Ah just found out about the dark cases... seems to only happen if the number is in first position though

"12blah".to_i => 12

Here's my working Async Pure Javascript from 2020

function testFileExists(src, successFunc, failFunc) {
    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function () {
        if (this.readyState === this.DONE) {
            if (xhr.status === 200) {
                successFunc(xhr);
            } else {
                failFunc(xhr);
            }
        }
    }
    // xhr.error = function() {
    //     failFunc(xhr);
    // }
    // xhr.onabort = function() {
    //     failFunc(xhr);
    // }
    // xhr.timeout = function() {
    //     failFunc(xhr);
    // }
    xhr.timeout = 5000;           // TIMEOUT SET TO PREFERENCE (5 SEC)
    xhr.open('HEAD', src, true);
    xhr.send(null);               // VERY IMPORTANT
}
function fileExists(xhr) {
    alert("File exists !!  Yay !!");
}
function fileNotFound(xhr) {
    alert("Cannot find the file, bummer");
}
testFileExists("test.html", fileExists, fileNotFound);

I could not force it to come back with any of the abort, error, or timeout callbacks. Each one of these returned a main status code of 0, in the test above, so I removed them. You can experiment. I set the timeout to 5 seconds as the default seems to be very excessive. With the Async call, it doesn't seem to do anything without the send() command.

Try this

$('#searchbox input').bind('keypress', function(e) {
    if(e.keyCode==13){
        // Enter pressed... do anything here...
    }
});

You can use the data attribute of the select element

<select id="my_select" data-default-value="b">
    <option value="a">a</option>
    <option value="b" selected="selected">b</option>
    <option value="c">c</option>
</select>

Your JavaScript,

$("#reset").on("click", function () {
    $("#my_select").val($("#my_select").data("default-value"));
});

http://jsfiddle.net/T8sCf/10/

UPDATE

If you don't know the default selection and if you cannot update the html, add following code in the dom ready ,

$("#my_select").data("default-value",$("#my_select").val());

            wb = new XSSFWorkbook(fs);

               Sheet_name= wb.GetSheetAt(0).SheetName;  //get first sheet name
        }
        DataTable DT = new DataTable();
        DT.Rows.Clear();
        DT.Columns.Clear();

        // get sheet
        sh = (XSSFSheet)wb.GetSheet(Sheet_name);

        int i = 0;
        while (sh.GetRow(i) != null)
        {
            // add neccessary columns
            if (DT.Columns.Count < sh.GetRow(i).Cells.Count)
            {
                for (int j = 0; j < sh.GetRow(i).Cells.Count; j++)
                {
                    DT.Columns.Add("", typeof(string));
                }
            }

            // add row
            DT.Rows.Add();

            // write row value
            for (int j = 0; j < sh.GetRow(i).Cells.Count; j++)
            {
                var cell = sh.GetRow(i).GetCell(j);

                if (cell != null)
                {
                    // TODO: you can add more cell types capatibility, e. g. formula
                    switch (cell.CellType)
                    {
                        case NPOI.SS.UserModel.CellType.Numeric:
                            DT.Rows[i][j] = sh.GetRow(i).GetCell(j).NumericCellValue;
                            //dataGridView1[j, i].Value = sh.GetRow(i).GetCell(j).NumericCellValue;

                            break;
                        case NPOI.SS.UserModel.CellType.String:

                            break;
                    }
                }
            }

            i++;
        }

        return DT;
    }

Another option altogether is to detach the database via Management Studio. Then simply delete the log file, or rename it and delete later.

Back in Management Studio attach the database again. In the attach window remove the log file from list of files.

The DB attaches and creates a new empty log file. After you check everything is all right, you can delete the renamed log file.

You probably ought not use this for production databases.

From the documentation page

To set the page type pass the value in constructor

jsPDF(orientation, unit, format) Creates new jsPDF document object

instance Parameters:

orientation One of "portrait" or "landscape" (or shortcuts "p" (Default), "l")

unit Measurement unit to be used when coordinates are specified. One of "pt" (points), "mm" (Default), "cm", "in"

format One of 'a3', 'a4' (Default),'a5' ,'letter' ,'legal'

To set font size

setFontSize(size)

Sets font size for upcoming text elements.

Parameters:

{Number} size Font size in points.

To really update just one package install NCU and then run it just for that package. This will bump to the real latest.

npm install -g npm-check-updates

ncu -f your-intended-package-name -u

This is my solution. When Set-Location fails it throws a non-terminating error which is not seen by the catch block. Adding -ErrorAction Stop is the easiest way around this.

try {
    Set-Location "$YourPath" -ErrorAction Stop;
} catch {
    Write-Host "Exception has been caught";
}

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

You are applying the formatting to the workbook that has the code, not the added workbook. You'll want to get in the habit of fully qualifying sheet and range references. The code below does that and works for me in Excel 2010:

Sub test()
Dim wb As Excel.Workbook
Set wb = Workbooks.Add
With wb.Sheets(1)
    .Range("A1") = "Acctdate"
    .Range("B1") = "Ledger"
    .Range("C1") = "CY"
    .Range("D1") = "BusinessUnit"
    .Range("E1") = "OperatingUnit"
    .Range("F1") = "LOB"
    .Range("G1") = "Account"
    .Range("H1") = "TreatyCode"
    .Range("I1") = "Amount"
    .Range("J1") = "TransactionCurrency"
    .Range("K1") = "USDEquivalentAmount"
    .Range("L1") = "KeyCol"
    .Range("A2", "A50000").Value = Me.TextBox3.Value
    .Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"
End With
End Sub

i wanted to know the number of directories, files an MB of just the current directory - and that code does exactly what i want :-)

Mine is working awesome .

In situations where the class under test can be modified and when it's desirable to avoid byte code manipulation, to keep things fast or to minimise third party dependencies, here is my take on the use of a factory to extract the new operation.

public class TestedClass {

    interface PojoFactory { Pojo getNewPojo(); }

    private final PojoFactory factory;

    /** For use in production - nothing needs to change. */
    public TestedClass() {
        this.factory = new PojoFactory() {
            @Override
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };
    }

    /** For use in testing - provide a pojo factory. */
    public TestedClass(PojoFactory factory) {
        this.factory = factory;
    }

    public void doSomething() {
        Pojo pojo = this.factory.getNewPojo();
        anythingCouldHappen(pojo);
    }
}

With this in place, your testing, asserts and verify calls on the Pojo object are easy:

public  void testSomething() {
    Pojo testPojo = new Pojo();
    TestedClass target = new TestedClass(new TestedClass.PojoFactory() {
                @Override
                public Pojo getNewPojo() {
                    return testPojo;
                }
            });
    target.doSomething();
    assertThat(testPojo.isLifeStillBeautiful(), is(true));
}

The only downside to this approach potentially arises if TestClass has multiple constructors which you'd have to duplicate with the extra parameter.

For SOLID reasons you'd probably want to put the PojoFactory interface onto the Pojo class instead, and the production factory as well.

public class Pojo {

    interface PojoFactory { Pojo getNewPojo(); }

    public static final PojoFactory productionFactory = 
        new PojoFactory() {
            @Override 
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };

The most elegant way to fix this: use pipe. Here is example (my blog). So you can then simply use url | safe pipe to bypass the security.

<iframe [src]="url | safe"></iframe>

Refer to the documentation on npm for details: https://www.npmjs.com/package/safe-pipe

        }
        logger.info(message);
    }
    public static void error(String message){
        System.out.println(message);
    }

}

You can try: .order_by(ClientTotal.id.desc())

session = Session()
auth_client_name = 'client3' 
result_by_auth_client = session.query(ClientTotal).filter(ClientTotal.client ==
auth_client_name).order_by(ClientTotal.id.desc()).all()

for rbac in result_by_auth_client:
    print(rbac.id) 
session.close()

Precision is the number of significant digits. Oracle guarantees the portability of numbers with precision ranging from 1 to 38.

Scale is the number of digits to the right (positive) or left (negative) of the decimal point. The scale can range from -84 to 127.

In your case, ID with precision 6 means it won't accept a number with 7 or more significant digits.

Reference:

http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/datatype.htm#CNCPT1832

That page also has some examples that will make you understand precision and scale.

It's "a reference to the object in the current context" effectively. For example, to print out "this object" you might write:

System.out.println(this);

Note that your usage of "global variable" is somewhat off... if you're using this.variableName then by definition it's not a global variable - it's a variable specific to this particular instance.

Style the ::-ms-clear pseudo-element for the box:

.someinput::-ms-clear {
    display: none;
}

To go back to original app you can use telprompt:// instead of tel:// - The tell prompt will prompt the user first, but when the call is finished it will go back to your app:

NSString *phoneNumber = [@"telprompt://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

We can also focus webelement using below code:

public focusElement(WebElement element){
    String javaScript = "var evObj = document.createEvent('MouseEvents');"
                    + "evObj.initMouseEvent(\"mouseover\",true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);"
                    + "arguments[0].dispatchEvent(evObj);";

            ((JavascriptExecutor) getDriver()).executeScript(javaScript, element);
}

Hope it helps :)

Another option might be to merge with strategy ours to the commit before the range and then a 'normal' merge with the last commit of that range (or branch when it is the last one). So suppose only 2345 and 3456 commits of master to be merged into feature branch:

master:
1234
2345
3456
4567

in feature branch:

git merge -s ours 4567
git merge 2345

use it when you delete row using selectedTag of row.

self.tableView.beginUpdates()

        self.yourArray.remove(at:  self.selectedTag)
        print(self.allGroups)

        let indexPath = NSIndexPath.init(row:  self.selectedTag, section: 0)

        self.tableView.deleteRows(at: [indexPath as IndexPath], with: .automatic)

        self.tableView.endUpdates()

        self.tableView.reloadRows(at: self.tableView.indexPathsForVisibleRows!, with: .automatic)

function last_monday($date)

    if (!is_numeric($date))
        $date = strtotime($date);
    if (date('w', $date) == 1)
        return $date;
    else
        return date('Y-m-d',strtotime('last monday',$date));
}
$date = '2021-01-04';  //Enter custom date
$year = date('Y',strtotime($date));
$date1 = new DateTime($date);
$ldate = last_monday($year."-01-01");
$date2 = new DateTime($ldate);
$diff = $date2->diff($date1)->format("%a");
$diff = $diff/7;
$week = intval($diff) + 1;
echo $week;
//Returns 2.

It's a language abstraction - some languages have both, some one, some neither.

In the case of C++, the code is not run in either the stack or the heap. You can test what happens if you run out of heap memory by repeatingly calling new to allocate memory in a loop without calling delete to free it it. But make a system backup before doing this.

On Ubuntu under flask webframework this should be working

pytesseract.pytesseract.tesseract_cmd = r"/usr/bin/tesseract"
img = Image.open(picture_name)
print(pytesseract.image_to_string(img))

To copy a sheet to a workbook called TARGET:

Sheets("xyz").Copy After:=Workbooks("TARGET.xlsx").Sheets("abc")

This will put the copied sheet xyz in the TARGET workbook after the sheet abc Obviously if you want to put the sheet in the TARGET workbook before a sheet, replace Before for After in the code.

To create a workbook called TARGET you would first need to add a new workbook and then save it to define the filename:

Application.Workbooks.Add (xlWBATWorksheet)
ActiveWorkbook.SaveAs ("TARGET")

However this may not be ideal for you as it will save the workbook in a default location e.g. My Documents.

Hopefully this will give you something to go on though.

Another problem (that I ran into) is that Cygwin's unzip utility (UnZip 6.00 of 20 April 2009, by Cygwin. Original by Info-ZIP.) does not always correctly unzip everything needed for Eclipse to actually run.

Using 7ZIP v9.20 got Eclipse Indigo (3.7.2) up and running for me on Win7 64bit with 32bit JVM and 32bit Eclipse.

(First time I've ever had Cygwin's unzip fail on me...)

The answer is no. Bash doesn't allocate any output to any parameter or any block on its memory. Also, you are only allowed to access Bash by its allowed interface operations. Bash's private data is not accessible unless you hack it.

Be careful with the "Range(...)" without first qualifying a Worksheet because it will use the currently Active worksheet to make the copy from. It's best to fully qualify both sheets. Please give this a shot (please change "Sheet1" with the copy worksheet):

EDIT: edited for pasting values only based on comments below.

Private Sub CommandButton1_Click()
  Application.ScreenUpdating = False

I am using Visual Studio 2013 and Win 8.1. It was Shift + 0 (0 is my insert key) on the number pad of my laptop.

FWIW Here is a quick-n-dirty code I wrote for inserting to an arbitrary index position. Not necessarily efficient but it works in-place.

class OrderedDictInsert(OrderedDict):
    def insert(self, index, key, value):
        self[key] = value
        for ii, k in enumerate(list(self.keys())):
            if ii >= index and k != key:
                self.move_to_end(k)

It may also be that you need to run the console as an administrator. On windows 7, hold ctrl+shift when you launch the console window.

You can achieve almost everything in PROCESS_NUM with this one-liner:

[ `pgrep $1` ] && return 1 || return 0

if you're looking for a partial match, i.e. program is named foobar and you want your $1 to be just foo you can add the -f switch to pgrep:

[[ `pgrep -f $1` ]] && return 1 || return 0

Putting it all together your script could be reworked like this:

#!/bin/bash

check_process() {
  echo "$ts: checking $1"
  [ "$1" = "" ]  && return 0
  [ `pgrep -n $1` ] && return 1 || return 0
}

while [ 1 ]; do 
  # timestamp
  ts=`date +%T`

  echo "$ts: begin checking..."
  check_process "dropbox"
  [ $? -eq 0 ] && echo "$ts: not running, restarting..." && `dropbox start -i > /dev/null`
  sleep 5
done

Running it would look like this:

# SHELL #1
22:07:26: begin checking...
22:07:26: checking dropbox
22:07:31: begin checking...
22:07:31: checking dropbox

# SHELL #2
$ dropbox stop
Dropbox daemon stopped.

# SHELL #1
22:07:36: begin checking...
22:07:36: checking dropbox
22:07:36: not running, restarting...
22:07:42: begin checking...
22:07:42: checking dropbox

Hope this helps!

Specify the property in filter, of object on which you want to apply filter:

//Suppose Object
var users = [{
  "firstname": "XYZ",
  "lastname": "ABC",
  "Address": "HOUSE NO-1, Example Street, Example Town"
},
{
  "firstname": "QWE",
  "lastname": "YUIKJH",
  "Address": "HOUSE NO-11, Example Street1, Example Town1"
}]

But you want to apply filter only on firstname

<input type = "text" ng-model = "first_name_model"/>
<div ng-repeat="user in users| filter:{ firstname: first_name_model}">

As has been explained by many, object defines a singleton instance. The one thing in the answers here that I believe is left out is that object serves several purposes.

• It can be the companion object to a class/trait, containing what might be considered static methods or convenience methods.

• It can act much like a module, containing related/subsidiary types and definitions, etc.

• It can implement an interface by extending a class or one or more traits.

• It can represent a case of a sealed trait that contains no data. In this respect, it's often considered more correct than a case class with no parameters. The special case of a sealed trait with only case object implementors is more or less the Scala version of an enum.

• It can act as evidence for implicit-driven logic.

• It introduces a singleton type.

It's a very powerful and general construct. What can be very confusing to Scala beginners is that the same construct can have vastly different uses. And an object can serve many of these different uses all at once, which can be even more confusing.

The other answers demonstrate the difference between array_walk (in-place modification) and array_map (return modified copy) quite well. However, they don't really mention array_reduce, which is an illuminating way to understand array_map and array_filter.

The array_reduce function takes an array, a two-argument function and an 'accumulator', like this:

array_reduce(array('a', 'b', 'c', 'd'),
             'my_function',
             $accumulator)

The array's elements are combined with the accumulator one at a time, using the given function. The result of the above call is the same as doing this:

my_function(
  my_function(
    my_function(
      my_function(
        $accumulator,
        'a'),
      'b'),
    'c'),
  'd')

If you prefer to think in terms of loops, it's like doing the following (I've actually used this as a fallback when array_reduce wasn't available):

function array_reduce($array, $function, $accumulator) {
  foreach ($array as $element) {
    $accumulator = $function($accumulator, $element);
  }
  return $accumulator;
}

This looping version makes it clear why I've called the third argument an 'accumulator': we can use it to accumulate results through each iteration.

So what does this have to do with array_map and array_filter? It turns out that they're both a particular kind of array_reduce. We can implement them like this:

array_map($function, $array)    === array_reduce($array, $MAP,    array())
array_filter($array, $function) === array_reduce($array, $FILTER, array())

Ignore the fact that array_map and array_filter take their arguments in a different order; that's just another quirk of PHP. The important point is that the right-hand-side is identical except for the functions I've called $MAP and $FILTER. So, what do they look like?

$MAP = function($accumulator, $element) {
  $accumulator[] = $function($element);
  return $accumulator;
};

$FILTER = function($accumulator, $element) {
  if ($function($element)) $accumulator[] = $element;
  return $accumulator;
};

As you can see, both functions take in the $accumulator and return it again. There are two differences in these functions:

• $MAP will always append to $accumulator, but $FILTER will only do so if $function($element) is TRUE.
• $FILTER appends the original element, but $MAP appends $function($element).

Note that this is far from useless trivia; we can use it to make our algorithms more efficient!

We can often see code like these two examples:

// Transform the valid inputs
array_map('transform', array_filter($inputs, 'valid'))

// Get all numeric IDs
array_filter(array_map('get_id', $inputs), 'is_numeric')

Using array_map and array_filter instead of loops makes these examples look quite nice. However, it can be very inefficient if $inputs is large, since the first call (map or filter) will traverse $inputs and build an intermediate array. This intermediate array is passed straight into the second call, which will traverse the whole thing again, then the intermediate array will need to be garbage collected.

We can get rid of this intermediate array by exploiting the fact that array_map and array_filter are both examples of array_reduce. By combining them, we only have to traverse $inputs once in each example:

// Transform valid inputs
array_reduce($inputs,
             function($accumulator, $element) {
               if (valid($element)) $accumulator[] = transform($element);
               return $accumulator;
             },
             array())

// Get all numeric IDs
array_reduce($inputs,
             function($accumulator, $element) {
               $id = get_id($element);
               if (is_numeric($id)) $accumulator[] = $id;
               return $accumulator;
             },
             array())

NOTE: My implementations of array_map and array_filter above won't behave exactly like PHP's, since my array_map can only handle one array at a time and my array_filter won't use "empty" as its default $function. Also, neither will preserve keys.

It's not difficult to make them behave like PHP's, but I felt that these complications would make the core idea harder to spot.

SchemaCrawler for PostgreSQL can generate database diagrams from the command line, with the help of GraphViz. You can use regular expressions to include and exclude tables and columns. It can also infer relationships between tables using common naming conventions, if not foreign keys are defined.

Try the following:

<c:set var="count" value="0" scope="page" />

//in your loops
<c:set var="count" value="${count + 1}" scope="page"/>

There is a modern port for this Turbo C graphics interface, it's called WinBGIM, which emulates BGI graphics under MinGW/GCC.

I haven't it tried but it looks promising. For example initgraph creates a window, and from this point you can draw into that window using the good old functions, at the end closegraph deletes the window. It also has some more advanced extensions (eg. mouse handling and double buffering).

When I first moved from DOS programming to Windows I didn't have internet, and I begged for something simple like this. But at the end I had to learn how to create windows and how to handle events and use device contexts from the offline help of the Windows SDK.

What levi said about passing it into the constructor is correct, but you could also use an object.

I think what Veverke is trying to say is that you could easily use the delete keyword on an object to achieve the same effect.

I think you're confused by the terminology; properties are components of the object that you can use as named indices (if you want to think of it that way).

Try something like this:

var obj = {
    "bob": "dole",
    "mr.": "peabody",
    "darkwing": "duck"
};

Then, you could just do this:

delete obj["bob"];

The structure of the object would then be this:

{
    "mr.": "peabody",
    "darkwing": "duck"
}

Which has the same effect.

Although the existing answers are valid approaches , they are antiquated . HttpClient is a modern interface for working with RESTful web services . Check the examples section of the page in the link , it has a very straightforward use case for an asynchronous HTTP GET .

using (var client = new System.Net.Http.HttpClient())
{
    return await client.GetStringAsync("https://reqres.in/api/users/3"); //uri
}

Maybe you need "sys." before:

select * from sys.registry$history;

The most efficient way would be using a matcher to continually find the expressions and replace them, then append the text to a string builder:

Pattern pattern = Pattern.compile("\\[(.+?)\\]");
Matcher matcher = pattern.matcher(text);
HashMap<String,String> replacements = new HashMap<String,String>();
//populate the replacements map ...
StringBuilder builder = new StringBuilder();
int i = 0;
while (matcher.find()) {
    String replacement = replacements.get(matcher.group(1));
    builder.append(text.substring(i, matcher.start()));
    if (replacement == null)
        builder.append(matcher.group(0));
    else
        builder.append(replacement);
    i = matcher.end();
}
builder.append(text.substring(i, text.length()));
return builder.toString();

Got an awesome function here.

    $platform = 'mac';
  }elseif (preg_match('/windows|win32/i', $u_agent)) {

  // Next get the name of the useragent yes seperately and for good reason

There is a good blog about this topic: http://www.baeldung.com/jackson-serialize-dates Use @JsonFormat looks the most simple way.

public class Event {

    public Date eventDate;
}

Here are 4 ways to insert data into a table.

1. Simple insertion when the table column sequence is known.

   INSERT INTO Table1 VALUES (1,2,...)

2. Simple insertion into specified columns of the table.

   INSERT INTO Table1(col2,col4) VALUES (1,2)

3. Bulk insertion when...

   1. You wish to insert every column of Table2 into Table1
   2. You know the column sequence of Table2
   3. You are certain that the column sequence of Table2 won't change while this statement is being used (perhaps you the statement will only be used once).

   INSERT INTO Table1 {Column sequence} SELECT * FROM Table2

4. Bulk insertion of selected data into specified columns of Table2.

.

INSERT INTO Table1 (Column1,Column2 ....)
    SELECT Column1,Column2...
       FROM Table2

In my case (NET Core 3.1) I fixed it by giving it an AssemblyName tag in the ProjectGroup section of the project file. e.g.

<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <UseWPF>true</UseWPF>
    <AssemblyName>ProjectNameUsually</AssemblyName>
  </PropertyGroup>
  ...
</Project>

This also fixed a problem it was having with the compiler not seeing a control by its x:Name in the code-behind.

The instanceof-operator is called is in Dart. The spec isn't exactly friendly to a casual reader, so the best description right now seems to be http://www.dartlang.org/articles/optional-types/.

Here's an example:

class Foo { }

main() {
  var foo = new Foo();
  if (foo is Foo) {
    print("it's a foo!");
  }
}

Why use int at all?

Apple uses int because for a loop control variable (which is only used to control the loop iterations) int datatype is fine, both in datatype size and in the values it can hold for your loop. No need for platform dependent datatype here. For a loop control variable even a 16-bit int will do most of the time.

Apple uses NSInteger for a function return value or for a function argument because in this case datatype [size] matters, because what you are doing with a function is communicating/passing data with other programs or with other pieces of code; see the answer to When should I be using NSInteger vs int? in your question itself...

they [Apple] use NSInteger (or NSUInteger) when passing a value as an argument to a function or returning a value from a function.

When I started using json, I was confused and unable to figure it out for some time, but finally I got what I wanted
Here is the simple solution

import json
m = {'id': 2, 'name': 'hussain'}
n = json.dumps(m)
o = json.loads(n)
print(o['id'], o['name'])

sleep infinity looks most elegant, but sometimes it doesn't work for some reason. In that case, you can try other blocking commands such as cat, read, tail -f /dev/null, grep a etc.

If you have downloaded the latest Version 4.3.4 then just follow these steps.

• Download the package, unzip and place in your web directory or root folder.
• Provide the read write permissions to that folder (preferably Ubuntu machines )
• Create view page test.php
• Paste the below mentioned code it should work fine.

Load the mentioned js file

<script type="text/javascript" src="/ckeditor/ckeditor.js"></script>
<textarea class="ckeditor" name="editor"></textarea>

The __init__ method, like other methods and functions returns None by default in the absence of a return statement, so you can write it like either of these:

class Foo:
    def __init__(self):
        self.value=42

class Bar:
    def __init__(self):
        self.value=42
        return None

But, of course, adding the return None doesn't buy you anything.

I'm not sure what you are after, but you might be interested in one of these:

class Foo:
    def __init__(self):
        self.value=42
    def __str__(self):
        return str(self.value)

f=Foo()
print f.value
print f

prints:

42
42

    if (HttpContext.User.Identity is ClaimsIdentity identity)
        {
            identity.RemoveClaim(identity.FindFirst("userId"));
            identity.AddClaim(new Claim("userId", userInfo?.id.ToString()));
            await HttpContext.SignInAsync(
                CookieAuthenticationDefaults.AuthenticationScheme,
                new ClaimsPrincipal(HttpContext.User.Identity));
        }

Use the .IndexOf() method of the list. Specs for the method can be found on MSDN.

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

Vanilla JS, without jQuery:

document.querySelector('#message span').innerHTML = 'hello world!'

Available in all browsers: https://caniuse.com/#search=querySelector

I normally use action="", which is XHTML valid and retains the GET data in the URL.

For MVC here was an even easier approach. You need to use the Ajax form and set the AjaxOptions

@using (Ajax.BeginForm("UploadTrainingMedia", "CreateTest", new AjaxOptions() { HttpMethod = "POST", OnComplete = "displayUploadMediaMsg" }, new { enctype = "multipart/form-data", id = "frmUploadTrainingMedia" }))
{ 
  ... html for form
}

here is the submission code, this is in the document ready section and ties the onclick event of the button to to submit the form

$("#btnSubmitFileUpload").click(function(e){
        e.preventDefault();
        $("#frmUploadTrainingMedia").submit();
});

here is the callback referenced in the AjaxOptions

function displayUploadMediaMsg(d){
    var rslt = $.parseJSON(d.responseText);
    if (rslt.statusCode == 200){
        $().toastmessage("showSuccessToast", rslt.status);
    }
    else{
        $().toastmessage("showErrorToast", rslt.status);
    }
}

in the controller method for MVC it looks like this

[HttpPost]
[ValidateAntiForgeryToken]
public JsonResult UploadTrainingMedia(IEnumerable<HttpPostedFileBase> files)
{
    if (files != null)
    {
        foreach (var file in files)
        {
            // there is only one file  ... do something with it
        }
        return Json(new
        {
            statusCode = 200,
            status = "File uploaded",
            file = "",
        }, "text/html");
    }
    else
    {
        return Json(new
        {
            statusCode = 400,
            status = "Unable to upload file",
            file = "",
        }, "text/html");
    }
}

Don't forget to include

import Image

In order to show it use this :

Image.open('pathToFile').show()

To redirect all http requests to https , you can use :

RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [NE,L,R]

If mod-rewrite isn't enabled and you are on apache 2.4, you can also use a Redirect inside if directive to redirect http requests to https .

Apache 2.4.

<if "%{HTTPS} !~ /on/">
Redirect / https://www.example.com/
</if>

When TOP is used with INSERT, UPDATE, MERGE, or DELETE, the referenced rows are not arranged in any order and the ORDER BY clause can not be directly specified in these statements. If you need to use TOP to insert, delete, or modify rows in a meaningful chronological order, you must use TOP together with an ORDER BY clause that is specified in a subselect statement.

TOP cannot be used in an UPDATE and DELETE statements on partitioned views.

TOP cannot be combined with OFFSET and FETCH in the same query expression (in the same query scope). For more information, see http://technet.microsoft.com/en-us/library/ms189463.aspx

Private types, internals and private members are so because of some reason, and often you don’t want to mess with them directly. And if you do, chances are that you’ll break later, because there is no guarantee that the guys who created those assemblies will keep the private/internal implementations as such.

But ,at times, when doing some hacks/exploration of compiled or third party assemblies, I have myself ended up wanting to initialize a private class or a class with a private or internal constructor. Or, at times, when dealing with pre-compiled legacy libraries that I can’t change - I end up writing some tests against a private method.

Thus born the AccessPrivateWrapper - http://amazedsaint.blogspot.com/2010/05/accessprivatewrapper-c-40-dynamic.html - it's is a quick wrapper class that’ll make the job easy using C# 4.0 dynamic features and reflection.

You can create internal/private types like

    //Note that the wrapper is dynamic
    dynamic wrapper = AccessPrivateWrapper.FromType
        (typeof(SomeKnownClass).Assembly,"ClassWithPrivateConstructor");

    //Access the private members
    wrapper.PrivateMethodInPrivateClass();

Using sessionStorage for this is not possible.

From the MDN Docs

Opening a page in a new tab or window will cause a new session to be initiated.

That means that you can't share between tabs, for this you should use localStorage

One of the best semi solutions is to copy %1 into a variable and then use delayed expansion, as delayedExp. is always safe against any content.

set "param1=%~1"
setlocal EnableDelayedExpansion
if "!param1!"=="" ( echo it is empty )
rem ... or use the DEFINED keyword now
if defined param1 echo There is something

The advantage of this is that dealing with param1 is absolutly safe.

And the setting of param1 will work in many cases, like

test.bat hello"this is"a"test
test.bat you^&me

But it still fails with strange contents like

test.bat ^&"&

To be able to get a 100% correct answer for the existence

It detects if %1 is empty, but for some content it can't fetch the content.
This can be also be useful to distinguish between an empty %1 and one with "".
It uses the ability of the CALL command to fail without aborting the batch file.

@echo off
setlocal EnableDelayedExpansion
set "arg1="
call set "arg1=%%1"

if defined arg1 goto :arg_exists

set "arg1=#"
call set "arg1=%%1"
if "!arg1!" EQU "#" (
    echo arg1 exists, but can't assigned to a variable
    REM Try to fetch it a second time without quotes
    (call set arg1=%%1)
    goto :arg_exists
)

echo arg1 is missing
exit /b

:arg_exists
echo arg1 exists, perhaps the content is '!arg1!'

If you want to be 100% bullet proof to fetch the content, you could read How to receive even the strangest command line parameters?

Got it.

sort(mMyClassVector.begin(), mMyClassVector.end(), 
    [](const MyClass & a, const MyClass & b) -> bool
{ 
    return a.mProperty > b.mProperty; 
});

I assumed it'd figure out that the > operator returned a bool (per documentation). But apparently it is not so.

The getDate method of datepicker returns a date type, not a string.

You need to format the returned value to a string using your date format. Use datepicker's formatDate function:

var dateTypeVar = $('#datepicker').datepicker('getDate');
$.datepicker.formatDate('dd-mm-yy', dateTypeVar);

The full list of format specifiers is available here.

I think you're a little confused. PYTHONPATH sets the search path for importing python modules, not for executing them like you're trying.

PYTHONPATH Augment the default search path for module files. The format is the same as the shell’s PATH: one or more directory pathnames separated by os.pathsep (e.g. colons on Unix or semicolons on Windows). Non-existent directories are silently ignored.

In addition to normal directories, individual PYTHONPATH entries may refer to zipfiles containing pure Python modules (in either source or compiled form). Extension modules cannot be imported from zipfiles.

The default search path is installation dependent, but generally begins with prefix/lib/pythonversion (see PYTHONHOME above). It is always appended to PYTHONPATH.

An additional directory will be inserted in the search path in front of PYTHONPATH as described above under Interface options. The search path can be manipulated from within a Python program as the variable sys.path.

http://docs.python.org/2/using/cmdline.html#envvar-PYTHONPATH

What you're looking for is PATH.

export PATH=$PATH:/home/randy/lib/python 

However, to run your python script as a program, you also need to set a shebang for Python in the first line. Something like this should work:

#!/usr/bin/env python

And give execution privileges to it:

chmod +x /home/randy/lib/python/gbmx.py

Then you should be able to simply run gmbx.py from anywhere.

A small addition to @ghostdog74's answer about using case logic to check that array contains particular value:

myarray=(one two three)
word=two
case "${myarray[@]}" in  ("$word "*|*" $word "*|*" $word") echo "found" ;; esac

Or with extglob option turned on, you can do it like this:

myarray=(one two three)
word=two
shopt -s extglob
case "${myarray[@]}" in ?(*" ")"$word"?(" "*)) echo "found" ;; esac

Also we can do it with if statement:

myarray=(one two three)
word=two
if [[ $(printf "_[%s]_" "${myarray[@]}") =~ .*_\[$word\]_.* ]]; then echo "found"; fi

To compare values you can use a comparing method-

function naturalSorter(as, bs){
    var a, b, a1, b1, i= 0, n, L,
    rx=/(\.\d+)|(\d+(\.\d+)?)|([^\d.]+)|(\.\D+)|(\.$)/g;
    if(as=== bs) return 0;
    a= as.toLowerCase().match(rx);
    b= bs.toLowerCase().match(rx);
    L= a.length;
    while(i<L){
        if(!b[i]) return 1;
        a1= a[i],
        b1= b[i++];
        if(a1!== b1){
            n= a1-b1;
            if(!isNaN(n)) return n;
            return a1>b1? 1:-1;
        }
    }
    return b[i]? -1:0;
}

But for speed in sorting an array, rig the array before sorting, so you only have to do lower case conversions and the regular expression once instead of in every step through the sort.

function naturalSort(ar, index){
    var L= ar.length, i, who, next, 
    isi= typeof index== 'number', 
    rx=  /(\.\d+)|(\d+(\.\d+)?)|([^\d.]+)|(\.(\D+|$))/g;
    function nSort(aa, bb){
        var a= aa[0], b= bb[0], a1, b1, i= 0, n, L= a.length;
        while(i<L){
            if(!b[i]) return 1;
            a1= a[i];
            b1= b[i++];
            if(a1!== b1){
                n= a1-b1;
                if(!isNaN(n)) return n;
                return a1>b1? 1: -1;
            }
        }
        return b[i]!= undefined? -1: 0;
    }
    for(i= 0; i<L; i++){
        who= ar[i];
        next= isi? ar[i][index] || '': who;
        ar[i]= [String(next).toLowerCase().match(rx), who];
    }
    ar.sort(nSort);
    for(i= 0; i<L; i++){
        ar[i]= ar[i][1];
    }
}

+= is just a shortcut for writing

number = 4
number = number + 1

So instead you would write

numbers = 4
numbers += 1

Both ways are correct but example two helps you write a little less code

iisexpress program is responsible for that.

I guess this is what you need to look at: use onSizeChanged() of your view. Here is an EXTENDED code snippet on how to use onSizeChanged() to get your layout's or view's height and width dynamically http://syedrakibalhasan.blogspot.com/2011/02/how-to-get-width-and-height-dimensions.html

This worked for me and seems simple...

$(function() {
  $('#inlineDatepicker').datepicker({onSelect: showDate, defaultDate: '01/01/2010'});
});

<div style="font-size:75%";>
<div id="inlineDatepicker"></div>
</div>

properties-maven-plugin plugin may help:

If you have XDocument it is easier to use LINQ-to-XML:

var document = XDocument.Load(fileName);
var name = document.Descendants(XName.Get("Name", @"http://demo.com/2011/demo-schema")).First().Value;

If you are sure that XPath is the only solution you need:

using System.Xml.XPath;

var document = XDocument.Load(fileName);
var namespaceManager = new XmlNamespaceManager(new NameTable());
namespaceManager.AddNamespace("empty", "http://demo.com/2011/demo-schema");
var name = document.XPathSelectElement("/empty:Report/empty:ReportInfo/empty:Name", namespaceManager).Value;

you can try typescript's For :

selectChildren(data , $event){
   let parentChecked : boolean = data.checked;
   for(let o of this.hierarchicalData){
      for(let child of o){
         child.checked = parentChecked;
      }
   }
}

If you want to know how many files and sub-directories exist from the present working directory you can use this one-liner

find . -maxdepth 1 -type d -print0 | xargs -0 -I {} sh -c 'echo -e $(find {} | wc -l) {}' | sort -n

This will work in GNU flavour, and just omit the -e from the echo command for BSD linux (e.g. OSX).

Using jquery:

<form action="upload" enctype="multipart/form-data" method="post">
                
    Upload image:
    <input id="image-file" type="file" name="file" />
    <input type="submit" value="Upload" />

    <script type="text/javascript">
        $('#image-file').bind('change', function() {
            alert('This file size is: ' + this.files[0].size/1024/1024 + "MiB");
        });
    </script>

</form>

If you see below error message, when try into phpyAdmin:

New XAMPP security concept:
Access to the requested directory is only available from the local network.
This setting can be configured in the file "httpd-xampp.conf".

You can do next (for XAMPP, deployed on the UNIX-system): You can try change configuration for <Directory "/opt/lampp/phpmyadmin">

# vi /opt/lampp/etc/extra/httpd-xampp.conf

and change security settings to

#LoadModule perl_module        modules/mod_perl.so

<Directory "/opt/lampp/phpmyadmin">
    AllowOverride AuthConfig Limit
    Order allow,deny
    Allow from all
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

First - comment pl module, second - change config for node Directory. After it, you should restart httpd daemon

# /opt/lampp/xampp restart

Now you can access http://[server_ip]/phpmyadmin/

As the error notes, the problem is in the line:

if guess[i] == winning_numbers[i]

The error is that your list indices are out of range--that is, you are trying to refer to some index that doesn't even exist. Without debugging your code fully, I would check the line where you are adding guesses based on input:

for i in range(tickets):
    bubble = input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split(" ")
    guess.append(bubble)
print(bubble)

The size of how many guesses you are giving your user is based on

# Prompts the user to enter the number of tickets they wish to play.
tickets = int(input("How many lottery tickets do you want?\n"))

So if the number of tickets they want is less than 5, then your code here

for i in range(5):

if guess[i] == winning_numbers[i]:
    match = match+1

return match

will throw an error because there simply aren't that many elements in the guess list.

In order to get the image view with the proper size and in the center, you should use the following approach:

let width = 120 // choose the image width
let height = 20 // choose the image height
let titleView = UIView(frame: CGRect(x: 0, y: 0, width: view.bounds.width, height: 44)) //44 is the standard size of the top bar
let imageView = UIImageView(frame: CGRect(x: (view.bounds.width - width)/2, y: (44 - height)/2, width: width, height: height))
imageView.contentMode = .scaleAspectFit //choose other if it makes sense
imageView.image = UIImage(named: "your_image_name")
titleView.addSubview(imageView)
navigationItem.titleView = titleView

public List<Object> GetProjectForCombo()
{
    using (MyDataContext db = new MyDataContext (DBHelper.GetConnectionString()))
     {
         var query = from pro in db.Projects
                     select new {pro.ProjectName,pro.ProjectId};

         return query.ToList<Object>();
    }
}

You should really check till square root of num as sqrt(num) * sqrt(num) = num:

Something on these lines:

int square_root = (int) sqrt(num) + 1;
for (int i = 1; i < square_root; i++) { 
    if (num % i == 0&&i*i!=num)
        cout << i << num/i << endl;
    if (num % i == 0&&i*i==num)
        cout << i << '\n';
}

O(n) solution without any kind of sorting and using only one map.

public boolean isAnagram(String leftString, String rightString) {
  if (leftString == null || rightString == null) {
    return false;
  } else if (leftString.length() != rightString.length()) {
    return false;
  }

  Map<Character, Integer> occurrencesMap = new HashMap<>();

  for(int i = 0; i < leftString.length(); i++){
    char charFromLeft = leftString.charAt(i);
    int nrOfCharsInLeft = occurrencesMap.containsKey(charFromLeft) ? occurrencesMap.get(charFromLeft) : 0;
    occurrencesMap.put(charFromLeft, ++nrOfCharsInLeft);
    char charFromRight = rightString.charAt(i);
    int nrOfCharsInRight = occurrencesMap.containsKey(charFromRight) ? occurrencesMap.get(charFromRight) : 0;
    occurrencesMap.put(charFromRight, --nrOfCharsInRight);
  }

  for(int occurrencesNr : occurrencesMap.values()){
    if(occurrencesNr != 0){
      return false;
    }
  }

  return true;
}

and less generic solution but a little bit faster one. You have to place your alphabet here:

public boolean isAnagram(String leftString, String rightString) {
  if (leftString == null || rightString == null) {
    return false;
  } else if (leftString.length() != rightString.length()) {
    return false;
  }

  char letters[] = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'};
  Map<Character, Integer> occurrencesMap = new HashMap<>();
  for (char l : letters) {
    occurrencesMap.put(l, 0);
  }

  for(int i = 0; i < leftString.length(); i++){
    char charFromLeft = leftString.charAt(i);
    Integer nrOfCharsInLeft = occurrencesMap.get(charFromLeft);
    occurrencesMap.put(charFromLeft, ++nrOfCharsInLeft);
    char charFromRight = rightString.charAt(i);
    Integer nrOfCharsInRight = occurrencesMap.get(charFromRight);
    occurrencesMap.put(charFromRight, --nrOfCharsInRight);
  }

  for(Integer occurrencesNr : occurrencesMap.values()){
    if(occurrencesNr != 0){
      return false;
    }
  }

  return true;
}

I faced the same issue. Mongo DB repository was identified by Spring boot, but it was not creating Bean for a repository interface that extended the mongo repository.

The issue in my case was incorrect version specification in maven pom for "spring + mango". I have changed the artifact's group id and it all worked like magic. no annotations needed as spring boot took care of everything.

During my problem resolution, I was all over web searching for solutions and realized that this problem is actually project configuration related, anyone facing this issue should first check their project setup and enable debug from spring to get more details on failure and pay close attention to where exactly in the process, the creation has failed.

Use this code "./" as root on the server as it works for me

<a href="./fruits/index.html">Back to Fruits List</a>

but when you are on a local machine use the following code "../" as the root relative path

<a href="../fruits/index.html">Back to Fruits List</a>

You have to override your ; delimiter with something like $$ to avoid this kind of error.

After your function definition, you can set the delimiter back to ;.

This should work:

DELIMITER $$
CREATE FUNCTION F_Dist3D (x1 decimal, y1 decimal) 
RETURNS decimal
DETERMINISTIC
BEGIN 
  DECLARE dist decimal;
  SET dist = SQRT(x1 - y1);
  RETURN dist;
END$$
DELIMITER ;

This referes to http://blogs.msdn.com/b/pfxteam/archive/2012/02/12/10266988.aspx , http://winrtstoragehelper.codeplex.com/ , Windows 8 app store and .net 4.5

Here is my angle on this:

The async/await language feature makes many things fairly easy but it also introduces a scenario that was rarely encounter before it was so easy to use async calls: reentrance.

This is especially true for event handlers, because for many events you don't have any clue about whats happening after you return from the event handler. One thing that might actually happen is, that the async method you are awaiting in the first event handler, gets called from another event handler still on the same thread.

Here is a real scenario I came across in a windows 8 App store app: My app has two frames: coming into and leaving from a frame I want to load/safe some data to file/storage. OnNavigatedTo/From events are used for the saving and loading. The saving and loading is done by some async utility function (like http://winrtstoragehelper.codeplex.com/). When navigating from frame 1 to frame 2 or in the other direction, the async load and safe operations are called and awaited. The event handlers become async returning void => they cant be awaited.

However, the first file open operation (lets says: inside a save function) of the utility is async too and so the first await returns control to the framework, which sometime later calls the other utility (load) via the second event handler. The load now tries to open the same file and if the file is open by now for the save operation, fails with an ACCESSDENIED exception.

A minimum solution for me is to secure the file access via a using and an AsyncLock.

private static readonly AsyncLock m_lock = new AsyncLock();
...

using (await m_lock.LockAsync())
{
    file = await folder.GetFileAsync(fileName);
    IRandomAccessStream readStream = await file.OpenAsync(FileAccessMode.Read);
    using (Stream inStream = Task.Run(() => readStream.AsStreamForRead()).Result)
    {
        return (T)serializer.Deserialize(inStream);
    }
}

Please note that his lock basically locks down all file operation for the utility with just one lock, which is unnecessarily strong but works fine for my scenario.

Here is my test project: a windows 8 app store app with some test calls for the original version from http://winrtstoragehelper.codeplex.com/ and my modified version that uses the AsyncLock from Stephen Toub http://blogs.msdn.com/b/pfxteam/archive/2012/02/12/10266988.aspx.

May I also suggest this link: http://www.hanselman.com/blog/ComparingTwoTechniquesInNETAsynchronousCoordinationPrimitives.aspx

mhata dzenyu mese. its actually

var selectedGroups  = new Array();
$(".user_group[checked]").each(function() {
    selectedGroups.push($(this).val());
});

I use this query

SELECT id FROM table_name WHERE field_name REGEXP '"key_name":"([^"])key_word([^"])"';
or
SELECT id FROM table_name WHERE field_name RLIKE '"key_name":"[[:<:]]key_word[[:>:]]"';

The first query I use it to search partial value. The second query I use it to search exact word.

You could try a formatter like this

They will always be limited because they don't (and can't) know what user defined functions you may have defined in your database (or which built-in functions you have or don't have access to).

You could also look at ANTLR (but that would be an offline solution)

You need to read up on event bubbling and for sure remove inline event handling if you have jQuery anyway

Test the click on the div and examine the target

Live Demo

$(".expandable-panel-heading").on("click",function (e) {
    if (e.target.id =="ancherComplaint") { // or test the tag
        e.preventDefault(); // or e.stopPropagation()
        markActiveLink(e.target);
    }    
    else alert('123');
});
function markActiveLink(el) {   
    alert(el.id);

One more way:

>>> ''.join([''.join(el) for el in zip(s[1::2], s[0::2])])
'214365'

My situation was settings text color in the options menu (main app menu showed on menu button press).

Tested in API 16 with appcompat-v7-27.0.2 library, AppCompatActivity for MainActivity and AppCompat theme for the application in AndroidManifest.xml.

styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="actionBarPopupTheme">@style/PopupTheme</item>
</style>

<style name="PopupTheme" parent="@style/ThemeOverlay.AppCompat.Light">
  <item name="android:textColorSecondary">#f00</item>
</style>

Don't know if that textColorSecondary affects other elements but it controls the menu text color.

I searched some examples on the topic but all ready-to-use snippets didn't work.

So I wanted to investigate it with the source code for the appcompat-v7 library (specifically with the res folder of the .aar package).

Though in my case I used Eclipse with exploded .aar dependencies. So I could change the default styles and check the results. Don't know how to explode the libraries to use with Gradle or Android Studio directly. It deserves another thread of investigation.

So my purpose was so find which color in the res/values/values.xml file is used for the menu text (I was almost sure the color was there).

1. I opened that file, then duplicated all colors, put them below the default ones to override them and assigned #f00 value to all of them.
2. Start the app.
3. Many elements had red background or text color. And the menu items too. That was what I needed.
4. Removing my added colors by blocks of 5-10 lines I ended with the secondary_text_default_material_light color item.
5. Searching that name in the files within the res folder (or better within res/colors) I found only one occurrence in the color/abc_secondary_text_material_light.xml file (I used Sublime Text for these operations so it's easier to find thing I need).
6. Back to the values.xml 8 usages were found for the @color/abc_secondary_text_material_light.
7. It was a Light theme so 4 left in 2 themes: Base.ThemeOverlay.AppCompat.Light and Platform.AppCompat.Light.
8. The first theme was a child of the second one so there were only 2 attributes with that color resource: android:textColorSecondary and android:textColorTertiaryin the Base.ThemeOverlay.AppCompat.Light.
9. Changing their values directly in the values.xml and running the app I found that the final correct attribute was android:textColorSecondary.
10. Next I needed a theme or another attribute so I could change it in my app's style.xml (because my theme had as the parent the Theme.AppCompat.Light and not the ThemeOverlay.AppCompat.Light).
11. I searched in the same file for the Base.ThemeOverlay.AppCompat.Light. It had a child ThemeOverlay.AppCompat.Light.
12. Searching for the ThemeOverlay.AppCompat.Light I found its usage in the Base.Theme.AppCompat.Light.DarkActionBar theme as the actionBarPopupTheme attribute value.
13. My app's theme Theme.AppCompat.Light.DarkActionBar was a child of the found Base.Theme.AppCompat.Light.DarkActionBar so I could use that attribute in my styles.xml without problems.
14. As it's seen in the example code above I created a child theme from the mentioned ThemeOverlay.AppCompat.Light and changed the android:textColorSecondary attribute.

Another way is to use Cairographics-based SVG, PDF and PostScript Graphics Devices. This way you don't need to setEPS()

cairo_ps("image.eps")
plot(1, 10)
dev.off()
