comdlg32.dll is not a COM DLL and cannot be registered.

One way to confirm this for yourself is to run this command:

dumpbin /exports comdlg32.dll

You'll see that comdlg32.dll doesn't contain a DllRegisterServer method. Hence RegSvr32.exe won't work.

That's your answer.

ComDlg32.dll is a a system component. (exists in both c:\windows\system32 and c:\windows\syswow64) Trying to replace it or override any registration with an older version could corrupt the rest of Windows.

I can help more, but I need to know what MSComDlg.CommonDialog is. What does it do and how is it supposed to work? And what version of ComDlg32.dll are you trying to register (and where did you get it)?

on my Ubuntu 12.04 32 bit. I edit the command to:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

And on Ubuntu 12.04 64 bit try:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

The problem is that IE does not have the standard addEventListener method. IE uses its own attachEvent which does pretty much the same.

Good explanation of the differences, and also about the 3rd parameter can be found at quirksmode.

If anyone wonders for the Array version, it goes like this:

int i = Array.FindIndex(yourArray, x => x == itemYouWant);

In the first line of your JS code:

select.addEventListener('change', getSelection(this), false);

you're invoking getSelection by placing (this) behind the function reference. That is most likely not what you want, because you're now passing the return value of that call to addEventListener, instead of a reference to the actual function itself.

In a function invoked by addEventListener the value for this will automatically be set to the object the listener is attached to, productLineSelect in this case.

If that is what you want, you can just pass the function reference and this will in this example be select in invocations from addEventListener:

select.addEventListener('change', getSelection, false);

If that is not what you want, you'd best bind your value for this to the function you're passing to addEventListener:

var thisArg = { custom: 'object' };
select.addEventListener('change', getSelection.bind(thisArg), false);

The .bind part is also a call, but this call just returns the same function we're calling bind on, with the value for this inside that function scope fixed to thisArg, effectively overriding the dynamic nature of this-binding.

To get to your actual question: "How to pass parameters to function in addEventListener?"

You would have to use an additional function definition:

var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}, false);

Now we pass the event object, a reference to the value of this inside the callback of addEventListener, a variable defined and initialised inside that callback, and a variable from outside the entire addEventListener call to your own getSelection function.

We also might again have an object of our choice to be this inside the outer callback:

var thisArg = { custom: 'object' };
var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}.bind(thisArg), false);

num1 = 10 + 10*(someBoolValue is True)

That's my new final answer. Prior answer was as follows and was overkill for the stated problem. Getting_too_clever == not Good. Here's the prior answer... still good if you want add one thing for True cond and another for False:

num1 = 10 + (0,10)[someBoolValue is True]

You mentioned num1 would already have a value that should be left alone. I assumed num1 = 10 since that's the first statement of the post, so the operation to get to 20 is to add 10.

num1 = 10
someBoolValue = True

num1 = 10 + (0,10)[someBoolValue is True]

print(f'num1 = {num1}\nsomeBoolValue = {someBoolValue}')

produced this output

num1 = 20
someBoolValue = True

The answer is correct, however the perl documentation on how to handle deadlocks is a bit sparse and perhaps confusing with PrintError, RaiseError and HandleError options. It seems that rather than going with HandleError, use on Print and Raise and then use something like Try:Tiny to wrap your code and check for errors. The below code gives an example where the db code is inside a while loop that will re-execute an errored sql statement every 3 seconds. The catch block gets $_ which is the specific err message. I pass this to a handler function "dbi_err_handler" which checks $_ against a host of errors and returns 1 if the code should continue (thereby breaking the loop) or 0 if its a deadlock and should be retried...

$sth = $dbh->prepare($strsql);
my $db_res=0;
while($db_res==0)
{
   $db_res=1;
   try{$sth->execute($param1,$param2);}
   catch
   {
       print "caught $_ in insertion to hd_item_upc for upc $upc\n";
       $db_res=dbi_err_handler($_); 
       if($db_res==0){sleep 3;}
   }
}

dbi_err_handler should have at least the following:

sub dbi_err_handler
{
    my($message) = @_;
    if($message=~ m/DBD::mysql::st execute failed: Deadlock found when trying to get lock; try restarting transaction/)
    {
       $caught=1;
       $retval=0; # we'll check this value and sleep/re-execute if necessary
    }
    return $retval;
}

You should include other errors you wish to handle and set $retval depending on whether you'd like to re-execute or continue..

Hope this helps someone -

If you don't want 'a' in the index

In :

col = ['a','b','c']

data = DataFrame([[1,2,3],[10,11,12],[20,21,22]],columns=col)

I was facing problem with Ngx line chart xAxisTickFormatting function which was called from HTML like this: [xAxisTickFormatting]="xFormat". I was unable to access my component's variable from the function declared. This solution helped me to resolve the issue to find the correct this. Hope this helps the Ngx line chart, users.

instead of using the function like this:

xFormat (value): string {
  return value.toString() + this.oneComponentVariable; //gives wrong result 
}

Use this:

 xFormat = (value) => {
   // console.log(this);
   // now you have access to your component variables
   return value + this.oneComponentVariable
 }

My test string for the following:

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

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

If JS engines supported regexp lookbehinds, you could do:

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

Since it doesn't currently, you could:

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

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

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

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

A simple step to understand what is java and core java.

• Find a book for Java.

• Find a book for core java.

• Compare the content of both books.

Actual result: both have almost same content.

Result: Java and core java is same.

core java is just slang, to emphasize on deep knowledge of basic java. but if I say I know Java it doesn't mean that I don't have deep knowledge of basic java, or if I know everything in java.

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

A better answer is that ++i will sometimes be faster but never slower.

Everyone seems to be assuming that i is a regular built-in type such as int. In this case there will be no measurable difference.

However if i is complex type then you may well find a measurable difference. For i++ you must make a copy of your class before incrementing it. Depending on what's involved in a copy it could indeed be slower since with ++it you can just return the final value.

Foo Foo::operator++()
{
  Foo oldFoo = *this; // copy existing value - could be slow
  // yadda yadda, do increment
  return oldFoo;
}

Another difference is that with ++i you have the option of returning a reference instead of a value. Again, depending on what's involved in making a copy of your object this could be slower.

A real-world example of where this can occur would be the use of iterators. Copying an iterator is unlikely to be a bottle-neck in your application, but it's still good practice to get into the habit of using ++i instead of i++ where the outcome is not affected.

Create a custom Http class by extending the Angular 2 Http Provider and simply override the constructor and request method in you custom Http class. The example below adds Authorization header in every http request.

import {Injectable} from '@angular/core';
import {Http, XHRBackend, RequestOptions, Request, RequestOptionsArgs, Response, Headers} from '@angular/http';
import {Observable} from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';

@Injectable()
export class HttpService extends Http {

  constructor (backend: XHRBackend, options: RequestOptions) {
    let token = localStorage.getItem('auth_token'); // your custom token getter function here
    options.headers.set('Authorization', `Bearer ${token}`);
    super(backend, options);
  }

  request(url: string|Request, options?: RequestOptionsArgs): Observable<Response> {
    let token = localStorage.getItem('auth_token');
    if (typeof url === 'string') { // meaning we have to add the token to the options, not in url
      if (!options) {
        // let's make option object
        options = {headers: new Headers()};
      }
      options.headers.set('Authorization', `Bearer ${token}`);
    } else {
    // we have to add the token to the url object
      url.headers.set('Authorization', `Bearer ${token}`);
    }
    return super.request(url, options).catch(this.catchAuthError(this));
  }

  private catchAuthError (self: HttpService) {
    // we have to pass HttpService's own instance here as `self`
    return (res: Response) => {
      console.log(res);
      if (res.status === 401 || res.status === 403) {
        // if not authenticated
        console.log(res);
      }
      return Observable.throw(res);
    };
  }
}

Then configure your main app.module.ts to provide the XHRBackend as the ConnectionBackend provider and the RequestOptions to your custom Http class:

import { HttpModule, RequestOptions, XHRBackend } from '@angular/http';
import { HttpService } from './services/http.service';
...
@NgModule({
  imports: [..],
  providers: [
    {
      provide: HttpService,
      useFactory: (backend: XHRBackend, options: RequestOptions) => {
        return new HttpService(backend, options);
      },
      deps: [XHRBackend, RequestOptions]
    }
  ],
  bootstrap: [ AppComponent ]
})

After that, you can now use your custom http provider in your services. For example:

import { Injectable }     from '@angular/core';
import {HttpService} from './http.service';

@Injectable()
class UserService {
  constructor (private http: HttpService) {}

  // token will added automatically to get request header
  getUser (id: number) {
    return this.http.get(`/users/${id}`).map((res) => {
      return res.json();
    } );
  }
}

Here's a comprehensive guide - http://adonespitogo.com/articles/angular-2-extending-http-provider/

Where clause and args work together to form the WHERE statement of the SQL query. So say you looking to express

WHERE Column1 = 'value1' AND Column2 = 'value2'

Then your whereClause and whereArgs will be as follows

String whereClause = "Column1 =? AND Column2 =?";
String[] whereArgs = new String[]{"value1", "value2"};

If you want to select all table columns, i believe a null string passed to tableColumns will suffice.

Factory methods should be considered as an alternative to constructors - mostly when constructors aren't expressive enough, ie.

class Foo{
  public Foo(bool withBar);
}

is not as expressive as:

class Foo{
  public static Foo withBar();
  public static Foo withoutBar();
}

Factory classes are useful when you need a complicated process for constructing the object, when the construction need a dependency that you do not want for the actual class, when you need to construct different objects etc.

Android's preferred approach is int constants enforced with @IntDef:

public static final int GENDER_MALE = 1;
public static final int GENDER_FEMALE = 2;

@Retention(RetentionPolicy.SOURCE)
@IntDef ({GENDER_MALE, GENDER_FEMALE})
public @interface Gender{}

// Example usage...
void exampleFunc(@Gender int gender) {
  switch(gender) {
  case GENDER_MALE:

     break;
  case GENDER_FEMALE:
     // TODO
     break;
  }
}

@Emil's answer above is brilliant.

Small addition: We should ideally use TelephonyManager to detect network types. So the above should instead read:

/**
 * Check if there is fast connectivity
 * @param context
 * @return
 */
public static boolean isConnectedFast(Context context){
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = cm.getActiveNetworkInfo();
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    return (info != null && info.isConnected() && Connectivity.isConnectionFast(info.getType(), tm.getNetworkType()));
}

I required only one instance of the vertical padding, so I inserted this line in the appropriate place to avoid adding more to the css. <div style="margin-top:5px"></div>

It is correct that we need to look into the path ~/Library/Developer/CoreSimulator/Devices/.

But the issue I am seeing is that the path keeps changing every time I run the app. The path contains another set of long IDs after the Application string and that keeps changing every time I run the app. This basically means that my app will not have any cached data when it runs the next time.

You're going to want the second field after the colon, not the first.

grep -n "text to find" file.txt | cut -f2 -d:

1) Normally, you would want to return a Task. The main exception should be when you need to have a void return type (for events). If there's no reason to disallow having the caller await your task, why disallow it?

2) async methods that return void are special in another aspect: they represent top-level async operations, and have additional rules that come into play when your task returns an exception. The easiest way is to show the difference is with an example:

static async void f()
{
    await h();
}

static async Task g()
{
    await h();
}

static async Task h()
{
    throw new NotImplementedException();
}

private void button1_Click(object sender, EventArgs e)
{
    f();
}

private void button2_Click(object sender, EventArgs e)
{
    g();
}

private void button3_Click(object sender, EventArgs e)
{
    GC.Collect();
}

f's exception is always "observed". An exception that leaves a top-level asynchronous method is simply treated like any other unhandled exception. g's exception is never observed. When the garbage collector comes to clean up the task, it sees that the task resulted in an exception, and nobody handled the exception. When that happens, the TaskScheduler.UnobservedTaskException handler runs. You should never let this happen. To use your example,

public static async void AsyncMethod2(int num)
{
    await Task.Factory.StartNew(() => Thread.Sleep(num));
}

Yes, use async and await here, they make sure your method still works correctly if an exception is thrown.

Recently I was playing with this method too. I wrote a memoized algorithm to calcualte Fibonacci numbers which could serve as another illustration on how to use the method.

We can start by defining a map and putting the values in it for the base cases, namely, fibonnaci(0) and fibonacci(1):

private static Map<Integer,Long> memo = new HashMap<>();
static {
   memo.put(0,0L); //fibonacci(0)
   memo.put(1,1L); //fibonacci(1)
}

And for the inductive step all we have to do is redefine our Fibonacci function as follows:

public static long fibonacci(int x) {
   return memo.computeIfAbsent(x, n -> fibonacci(n-2) + fibonacci(n-1));
}

As you can see, the method computeIfAbsent will use the provided lambda expression to calculate the Fibonacci number when the number is not present in the map. This represents a significant improvement over the traditional, tree recursive algorithm.

He does some thorough performance comparison tests on;

• Autofac

• Ninject
• Unity
• Castle.Windsor
• Spring.Net

He recommends Autofac as it is small, fast, and easy to use ... I agree. It appears that Unity and Ninject are the slowest in his tests.

Firstly, we just CAN'T make the variable final as its state may be changing during the run of the program and our decisions within the inner class override may depend on its current state.

Secondly, good object-oriented programming practice suggests using only variables/constants that are vital to the class definition as class members. This means that if the variable we are referencing within the anonymous inner class override is just a utility variable, then it should not be listed amongst the class members.

But – as of Java 8 – we have a third option, described here :

https://docs.oracle.com/javase/tutorial/java/javaOO/localclasses.html

Starting in Java SE 8, if you declare the local class in a method, it can access the method's parameters.

So now we can simply put the code containing the new inner class & its method override into a private method whose parameters include the variable we call from inside the override. This static method is then called after the btnInsert declaration statement :-

 . . . .
 . . . .

 Statement statement = null;                                 

 . . . .
 . . . .

 Button btnInsert = new Button(shell, SWT.NONE);
 addMouseListener(Button btnInsert, Statement statement);    // Call new private method

 . . . 
 . . .
 . . . 

 private static void addMouseListener(Button btn, Statement st) // New private method giving access to statement 
 {
    btn.addMouseListener(new MouseAdapter() 
    {
      @Override
      public void mouseDown(MouseEvent e) 
      {
        String name = text.getText();
        String from = text_1.getText();
        String to = text_2.getText();
        String price = text_3.getText();
        String query = "INSERT INTO booking (name, fromst, tost,price) VALUES ('"+name+"', '"+from+"', '"+to+"', '"+price+"')";
        try 
        {
            st.executeUpdate(query);
        } 
        catch (SQLException e1) 
        {
            e1.printStackTrace();                                    // TODO Auto-generated catch block
        }
    }
  });
  return;
}

Apparently Chrome and Safari are wrong: onchange should only be triggered when the user releases the mouse. To get continuous updates, you should use the oninput event, which will capture live updates in Firefox, Safari and Chrome, both from the mouse and the keyboard.

However, oninput is not supported in IE10, so your best bet is to combine the two event handlers, like this:

<span id="valBox"></span>
<input type="range" min="5" max="10" step="1" 
   oninput="showVal(this.value)" onchange="showVal(this.value)">

Making it invisible with visibility still makes it use up space. Rather try set the display to none to make it invisible, and then set the display to block to make it visible.

Offset Means "the amount or distance by which something is out of line". Margin or Borders are something which makes the actual height or width of an HTML element "out of line". It will help you to remember that :

• offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.

On the other hand, clientHeight is something which is you can say kind of the opposite of OffsetHeight. It doesn't include the border or margins. It does include the padding because it is something that resides inside of the HTML container, so it doesn't count as extra measurements like margin or border. So :

• clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.

ScrollHeight is all the scrollable area, so your scroll will never run over your margin or border, so that's why scrollHeight doesn't include margin or borders but yeah padding does. So:

• scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.

This will give you the list of the procedures recently executed.

If you want to check if a perticular stored procedure executed recently

SELECT

    OBJECT_NAME(stats.object_id), 
    stats.last_execution_time

WHERE  
    sysobject.type = 'P'
    and (sysobject.object_id = object_id('schemaname.procedurename') 
    OR sysobject.name = 'procedurename')
ORDER BY

Here is an example how to do it for LENOVA or similar PC:

1. Start the machine.
2. Press F2 to enter BIOS.
3. Security-> System Security
4. Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
5. Save and restart the machine

Got scared to see complex answers, being new to C#.

Here are some simple answers.
Merging d1, d2, and so on.. dictionaries and handle any overlapping keys ("b" in below examples):

Example 1

{
    // 2 dictionaries,  "b" key is common with different values

    var d1 = new Dictionary<string, int>() { { "a", 10 }, { "b", 21 } };
    var d2 = new Dictionary<string, int>() { { "c", 30 }, { "b", 22 } };

    var result1 = d1.Concat(d2).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.First().Value);
    // result1 is  a=10, b=21, c=30    That is, took the "b" value of the first dictionary

    var result2 = d1.Concat(d2).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.Last().Value);
    // result2 is  a=10, b=22, c=30    That is, took the "b" value of the last dictionary
}

Example 2

{
    // 3 dictionaries,  "b" key is common with different values

    var d1 = new Dictionary<string, int>() { { "a", 10 }, { "b", 21 } };
    var d2 = new Dictionary<string, int>() { { "c", 30 }, { "b", 22 } };
    var d3 = new Dictionary<string, int>() { { "d", 40 }, { "b", 23 } };

    var result1 = d1.Concat(d2).Concat(d3).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.First().Value);
    // result1 is  a=10, b=21, c=30, d=40    That is, took the "b" value of the first dictionary

    var result2 = d1.Concat(d2).Concat(d3).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.Last().Value);
    // result2 is  a=10, b=23, c=30, d=40    That is, took the "b" value of the last dictionary
}

For more complex scenarios, see other answers.
Hope that helped.

The fastest way I know to generate a new-line character in Java is: String.format("%n")

Of course you can put whatever you want around the %n like:

String.format("line1%nline2")

Or even if you have a lot of lines:

String.format("%s%n%s%n%s%n%s", "line1", "line2", "line3", "line4")

this is variation of Dennis method, looks more elegant in the scripts.

function definition:

define(){ IFS='\n' read -r -d '' ${1} || true; }

usage:

define VAR <<'EOF'
abc'asdf"
$(dont-execute-this)
foo"bar"''
EOF

echo "$VAR"

enjoy

p.s. made a 'read loop' version for shells that do not support read -d. should work with set -eu and unpaired backticks, but not tested very well:

define(){ o=; while IFS="\n" read -r a; do o="$o$a"'
'; done; eval "$1=\$o"; }

import numpy as np   
>>> np.shape(a)
(2,2)

Also works if the input is not a numpy array but a list of lists

>>> a = [[1,2],[1,2]]
>>> np.shape(a)
(2,2)

Or a tuple of tuples

>>> a = ((1,2),(1,2))
>>> np.shape(a)
(2,2)

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

Source: regular-expressions.info

If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful.

This can be easily done by using enumerate function

code-

lst=[1,2,3,4,1,6,7,9,10,1,2]
for index,item in enumerate(lst):
    if item==1:
        lst[index]=10 #Replaces the item '1' in list with '10'

print(lst)

List comps are your friend.

print ", ".join("%.2f" % f for f in list_o_numbers)

Try it:

>>> nums = [9.0, 0.052999999999999999, 0.032575399999999997, 0.010892799999999999]
>>> print ", ".join("%.2f" % f for f in nums)
9.00, 0.05, 0.03, 0.01

If your repo have 2FA enabled. Highly suggest to use the app provided by github.com Here is the link: https://desktop.github.com/

After you downloaded it and installed it. Follow the withard, the app will ask you to provide the one time password for login. Once you filled in the one time password, you could see your repo/projects now.

$("#txtfromdate").datepicker({         
    numberOfMonths: 2,
    maxDate: 0,               
    dateFormat: 'dd-M-yy'       
}).attr('readonly', 'readonly');

add the readonly attribute in the jquery.

Try the :host > /deep/ :

Add the following to the parent.component.less file

:host {
    /deep/ app-child-component {
       //your child style
    }
}

Replace the app-child-component by your child selector

Another use case could be something like OAuth, it's may not be called by the API directly, instead the callback URL will be called by the browser after completing the authencation with the identity provider.

Normally after end user key in the username password, the identity service provider will trigger a browser redirect to your "callback" url with the temporary authroization code, e.g.

https://example.com/callback?code=AUTHORIZATION_CODE

Then your application could use this authorization code to request a access token with the identity provider which has a much longer lifetime.

I faced same problem. And got the solution when I use this code to call context. I use Grid Layout. If you use another one you can change.

   recyclerView.setLayoutManager(new GridLayoutManager(getActivity(),1));

if you have adapter to set. So you can follow this. Just call the getContext

  adapter = new Adapter(getContext(), myModelList);

If you have Toast to show, use same thing above

   Toast.makeText(getContext(), "Error in "+e, Toast.LENGTH_SHORT).show();

Hope this will work.

This will show last run status/time or if running, it shows current run time, step number/info, and SPID (if it has associated SPID). It also shows enabled/disabled and job user where it converts to NT SID format for unresolved user accounts.

And pass this as $cookie parameter:

$cookie_jar = tempnam('/tmp','cookie');

Go to the source folder where your project is.

1. Copy the project and past and change the name.
2. Open Android Studio and refresh.
3. Go to ->Settings.gradle.
4. Include ':your new project name '

Make sure the source file of the java class you are trying to refer to has a .java extension. It was .aj in my case (I must have hit "Create aspect" instead of "Create class" when creating it). IntelliJ shows the same icon for this file as for "normal" class, but compiler does not see it when building.

Changing .aj to .java fixed it in my case.

Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.

I had the same issue. The problem is that the Spring Boot annotation processor generates the spring-configuration-metadata.json file inside your /target/classes/META-INF folder.

If you happen to have ignored this folder in IntelliJ like me (because what the heck, who cares about classes files?), the file won't be indexed by your IDE. Therefore, no completion, and the annoying message.

Just remove target from the ignore files/folders list, located in Settings > Editor > File Types > Ignore files and folders.

I was upgrading a legacy instance of jQuery UI and found that there was an extension to the dialog widget and it was simply using "center" instead of the position object. Implementing the position object or removing the parameter entirely worked for me (because center is the default).

Like this:

for pet in pets :
  print(pet)

In fact, Python only has foreach style for loops.

Another possibility is using tidyr::expand:

library(dplyr)
library(tidyr)

df %>% group_by_at(vars(-freq)) %>% expand(temp = 1:freq) %>% select(-temp)

#> # A tibble: 6 x 2
#> # Groups:   var1, var2 [3]
#>   var1  var2 
#>   <fct> <fct>
#> 1 a     d    
#> 2 b     e    
#> 3 b     e    
#> 4 c     f    
#> 5 c     f    
#> 6 c     f

One-liner version of vonjd's answer:

library(data.table)

setDT(df)[ ,list(freq=rep(1,freq)),by=c("var1","var2")][ ,freq := NULL][]

#>    var1 var2
#> 1:    a    d
#> 2:    b    e
#> 3:    b    e
#> 4:    c    f
#> 5:    c    f
#> 6:    c    f

Well, REST by design is stateless. By adding session (or anything else of that kind) you are making it stateful and defeating any purpose of having a RESTful API.

The whole idea of RESTful service is that every resource is uniquely addressable using a universal syntax for use in hypermedia links and each HTTP request should carry enough information by itself for its recipient to process it to be in complete harmony with the stateless nature of HTTP".

So whatever you are trying to do with Web API here, should most likely be re-architectured if you wish to have a RESTful API.

With that said, if you are still willing to go down that route, there is a hacky way of adding session to Web API, and it's been posted by Imran here http://forums.asp.net/t/1780385.aspx/1

Code (though I wouldn't really recommend that):

public class MyHttpControllerHandler
  : HttpControllerHandler, IRequiresSessionState
{
    public MyHttpControllerHandler(RouteData routeData): base(routeData)
    { }
}

public class MyHttpControllerRouteHandler : HttpControllerRouteHandler
{
    protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        return new MyHttpControllerHandler(requestContext.RouteData);
    }
}

public class ValuesController : ApiController
{
   public string GET(string input)
   {
       var session = HttpContext.Current.Session;
       if (session != null)
       {
           if (session["Time"] == null)
           {
               session["Time"] = DateTime.Now;
           }
           return "Session Time: " + session["Time"] + input;
       }
       return "Session is not availabe" + input;
    }
}

and then add the HttpControllerHandler to your API route:

route.RouteHandler = new MyHttpControllerRouteHandler();

To get several and indepent columns, just:

> test[:,[0,2]]

you will get colums 0 and 2

A fancy way to solve it is by using twice "rev" and "cut":

find ./ -name "*.txt" | rev | cut -d '/' -f1 | rev

In my case, even after sign up to Visual Studio account, I cant sign in and the license still expired.

Solution from across the internet: Download iso version of the installer. Then run installer, select repair. That would solve the problem for most case.

In my case, I got an iso version of ms Visual Studio 2013. Installed it and I can successfully sign in and its forever free.

The new fontawesome (version 4.0.3) makes this really easy to do. We simply use the following classes:

<ul class="fa-ul">
  <li><i class="fa-li fa fa-check-square"></i>List icons (like these)</li>
  <li><i class="fa-li fa fa-check-square"></i>can be used</li>
  <li><i class="fa-li fa fa-spinner fa-spin"></i>to replace</li>
  <li><i class="fa-li fa fa-square"></i>default bullets in lists</li>
</ul>

As per this (new) url: http://fontawesome.io/examples/#list

You can simply use the terminal that comes with Android Studio. It is listed at the bottom of Android Studio. Just open it and use the cp command.

I do not know how does your PersonalizationGeoLocationServiceClientHelper works. Probably it performs some sort of caching, so requests for the same IP address may return extremely fast.

This code will convert the text 0xA7.0x9B.0x46.0x8D.0x1E.0x52.0xA7.0x9B.0x7B.0x31.0xD2 into a stream of 11 bytes with equivalent values. These bytes will be written to standard out.

TESTDATA=$(echo '0xA7.0x9B.0x46.0x8D.0x1E.0x52.0xA7.0x9B.0x7B.0x31.0xD2' | tr '.' ' ')
for c in $TESTDATA; do
    echo $c | xxd -r
done

As others have pointed out, this will not result in a printable ASCII string for the simple reason that the specified bytes are not ASCII. You need post more information about how you obtained this string for us to help you with that.

How it works: xxd -r translates hexadecimal data to binary (like a reverse hexdump). xxd requires that each line start off with the index number of the first character on the line (run hexdump on something and see how each line starts off with an index number). In our case we want that number to always be zero, since each execution only has one line. As luck would have it, our data already has zeros before every character as part of the 0x notation. The lower case x is ignored by xxd, so all we have to do is pipe each 0xhh character to xxd and let it do the work.

The tr translates periods to spaces so that for will split it up correctly.

You can use lineSpacingExtra and lineSpacingMultiplier in your XML file.

use grep -n -i null myfile.txt to output the line number in front of each match.

I dont think grep has a switch to print the count of total lines matched, but you can just pipe grep's output into wc to accomplish that:

grep -n -i null myfile.txt | wc -l

I have tried all methods, which are mentioned above.But no one method works for me.finally i got solution for above issue and it is working for me.

I tried this method:

In Html:

<li><a (click)= "aboutPageLoad()"  routerLinkActive="active">About</a></li>

In TS file:

aboutPageLoad() {
    this.router.navigate(['/about']);
}

The "simple" bidirectional dictionary solution proposed here is complex and may be be difficult to understand, maintain or extend. Also the original question asked for "the key for a value", but clearly there could be multiple keys (I've since edited the question). The whole approach is rather suspicious.

Software changes. Writing code that is easy to maintain should be given priority other "clever" complex workarounds. The way to get keys back from values in a dictionary is to loop. A dictionary isn't designed to be bidirectional.

You might try using a JEditorPane instead of a JLabel. This understands basic HTML and will send a HyperlinkEvent event to the HyperlinkListener you register with the JEditPane.

First the bigint(20) not null auto_increment will not work, simply use bigserial primary key. Then datetime is timestamp in PostgreSQL. All in all:

CREATE TABLE article (
    article_id bigserial primary key,
    article_name varchar(20) NOT NULL,
    article_desc text NOT NULL,
    date_added timestamp default NULL
);

With Swift 5 and iOS 12.3, according to your needs, you may choose one of the 3 following ways in order to solve your problem.

#1. Using UIView's animate(withDuration:animations:) class method

animate(withDuration:animations:) has the following declaration:

Animate changes to one or more views using the specified duration.

class func animate(withDuration duration: TimeInterval, animations: @escaping () -> Void)

The Playground code below shows a possible implementation of animate(withDuration:animations:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        UIView.animate(withDuration: 2) {
            self.view.layoutIfNeeded()
        }
    }

}

PlaygroundPage.current.liveView = ViewController()

#2. Using UIViewPropertyAnimator's init(duration:curve:animations:) initialiser and startAnimation() method

init(duration:curve:animations:) has the following declaration:

Initializes the animator with a built-in UIKit timing curve.

convenience init(duration: TimeInterval, curve: UIViewAnimationCurve, animations: (() -> Void)? = nil)

The Playground code below shows a possible implementation of init(duration:curve:animations:) and startAnimation() in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        let animator = UIViewPropertyAnimator(duration: 2, curve: .linear, animations: {
            self.view.layoutIfNeeded()
        })
        animator.startAnimation()
    }

}

PlaygroundPage.current.liveView = ViewController()

#3. Using UIViewPropertyAnimator's runningPropertyAnimator(withDuration:delay:options:animations:completion:) class method

runningPropertyAnimator(withDuration:delay:options:animations:completion:) has the following declaration:

Creates and returns an animator object that begins running its animations immediately.

class func runningPropertyAnimator(withDuration duration: TimeInterval, delay: TimeInterval, options: UIViewAnimationOptions = [], animations: @escaping () -> Void, completion: ((UIViewAnimatingPosition) -> Void)? = nil) -> Self

The Playground code below shows a possible implementation of runningPropertyAnimator(withDuration:delay:options:animations:completion:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false

        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        UIViewPropertyAnimator.runningPropertyAnimator(withDuration: 2, delay: 0, options: [], animations: {
            self.view.layoutIfNeeded()

One option would be VistaDB. They allow databases (or even tables) to be password protected (and optionally encrypted).

At some point I read a reasonably convincing argument on Perlmonks that testing the type of a scalar with ref or reftype is a bad idea. I don't recall who put the idea forward, or the link. Sorry.

The point was that in Perl there are many mechanisms that make it possible to make a given scalar act like just about anything you want. If you tie a filehandle so that it acts like a hash, the testing with reftype will tell you that you have a filehanle. It won't tell you that you need to use it like a hash.

So, the argument went, it is better to use duck typing to find out what a variable is.

Instead of:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;
    if( $type eq 'HASH' ) {
        $result = $var->{foo};
    }
    elsif( $type eq 'ARRAY' ) {
        $result = $var->[3];
    }
    else {
        $result = 'foo';
    }

    return $result;
}

You should do something like this:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;

    eval {
        $result = $var->{foo};
        1; # guarantee a true result if code works.
    }
    or eval { 
        $result = $var->[3];
        1;
    }
    or do {
        $result = 'foo';
    }

    return $result;
}

For the most part I don't actually do this, but in some cases I have. I'm still making my mind up as to when this approach is appropriate. I thought I'd throw the concept out for further discussion. I'd love to see comments.

Update

I realized I should put forward my thoughts on this approach.

This method has the advantage of handling anything you throw at it.

It has the disadvantage of being cumbersome, and somewhat strange. Stumbling upon this in some code would make me issue a big fat 'WTF'.

I like the idea of testing whether a scalar acts like a hash-ref, rather that whether it is a hash ref.

I don't like this implementation.

public class DynamicLinkedList
{

    private class Node
    {
        private object element;
        private Node next;

        public object Element
        {
            get { return this.element; }
            set { this.element = value; }
        }

        public Node Next
        {

    private int count;

    public DynamicLinkedList()
    {
        this.head = null;
        this.tail = null;
        this.count = 0;
    }

    public void AddAtLastPosition(object element)
    {
        if (head == null)
        {
            head = new Node(element);
            tail = head;
        }
        else
        {
            Node newNode = new Node(element, tail);
            tail = newNode;
        }

        count++;
    }

    public object GetLastElement()
    {
        object lastElement = null;
        Node currentNode = head;

        while (currentNode != null)

            currentNode = currentNode.Next;
        }

        return lastElement;
    }

}

Testing with:

static void Main(string[] args)
{
    DynamicLinkedList list = new DynamicLinkedList();
    list.AddAtLastPosition(1);
    list.AddAtLastPosition(2);
    list.AddAtLastPosition(3);
    list.AddAtLastPosition(4);
    list.AddAtLastPosition(5);

    object lastElement = list.GetLastElement();
    Console.WriteLine(lastElement);
}

We, the Javascript lovers, don't have to use Ruby (Jekyll or Octopress) to generate static pages in Github pages, we can use Node.js and Harp, for example:

These are the steps. Abstract:

1. Create a New Repository

2. Clone the Repository

   git clone https://github.com/your-github-user-name/your-github-user-name.github.io.git
   

3. Initialize a Harp app (locally):

   harp init _harp
   

make sure to name the folder with an underscore at the beginning; when you deploy to GitHub Pages, you don’t want your source files to be served.

4. Compile your Harp app

   harp compile _harp ./
   

5. Deploy to Gihub

   git add -A
   git commit -a -m "First Harp + Pages commit"
   git push origin master
   

And this is a cool tutorial with details about nice stuff like layouts, partials, Jade and Less.

Actually, you can process the find command output in a copy command in two ways:

1. If the find command's output doesn't contain any space, i.e if the filename doesn't contain a space in it, then you can use:

   Syntax:
       find <Path> <Conditions> | xargs cp -t <copy file path>
   Example:
       find -mtime -1 -type f | xargs cp -t inner/
   

2. But our production data files might contain spaces, so most of time this command is effective:

   Syntax:
      find <path> <condition> -exec cp '{}' <copy path> \;
   
   Example 
      find -mtime -1 -type f -exec cp '{}' inner/ \;
   

In the second example, the last part, the semi-colon is also considered as part of the find command, and should be escaped before pressing Enter. Otherwise you will get an error something like:

find: missing argument to `-exec'

If you're going to perform transfers on the waveform data then perhaps you should use SciPy, specifically scipy.io.wavfile.

When you see this trying to push to github you may have to initialize this repo at github first: https://github.com/new.

The problem is there is a JavaScript .focus and a jQuery .focus function. This call to .focus is ambiguous. So it doesn't always work. What I do is cast my jQuery object to a JavaScript object and use the JavaScript .focus. This works for me:

$("#goal-input")[0].focus();

The readarray command (also spelled mapfile) was introduced in bash 4.0.

readarray -t a < /path/to/filename

Here is the code for counting Null values column wise :

df.isna().sum()

this is old but for help :

you can also use the stringReader stream

string str = "asasdkopaksdpoadks";
StringReader TheStream = new StringReader( str );

There is a whole page in the MATLAB documentation dedicated to this topic: Array vs. Matrix Operations. The gist of it is below:

MATLAB® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.

Matrix operations follow the rules of linear algebra. By contrast, array operations execute element by element operations and support multidimensional arrays. The period character (.) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs .+ and .- are unnecessary.

I also face this issue but it is resolved in different way. Steps that I follow may be helpful for others.

1. Right click on project (the one you are working on)
2. Go to Properties > Java Build Path > JRE System Library
3. Click Edit... on the right
4. Choose the JRE 7

Just pass it in, like this:

Game(list_a, list_b, Rule1)

and then your Game function could look something like this (still pseudocode):

def Game(listA, listB, rules=None):
    if rules:
        # do something useful
        # ...
        result = rules(variable) # this is how you can call your rule
    else:
        # do something useful without rules

If you have a project ready and just want to change some code and then build. Check out MSBuild which is located in the Microsoft.Net under windows directory.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild "C:\Projects\MyProject.csproj" /p:Configuration=Debug;DeployOnBuild=True;PackageAsSingleFile=False;outdir=C:\Projects\MyProjects\Publish\

(Please do not edit, leave as a single line)

... The line above broken up for readability

C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild "C:\Projects\MyProject.csproj"
/p:Configuration=Debug;DeployOnBuild=True;PackageAsSingleFile=False;
outdir=C:\Projects\MyProjects\Publish\

I'm surprised no one mentioned passing it in "additionalViewData" and reading it on the other side.

View (with line breaks, for clarity):

        htmlAttributes = new
        {
            @class = "myClass"
        }
    }
)%>

I successfully put a portable version of libreoffice on my host's webserver, which I call with PHP to do a commandline conversion from .docx, etc. to pdf. on the fly. I do not have admin rights on my host's webserver. Here is my blog post of what I did:

http://geekswithblogs.net/robertphyatt/archive/2011/11/19/converting-.docx-to-pdf-or-.doc-to-pdf-or-.doc.aspx

Yay! Convert directly from .docx or .odt to .pdf using PHP with LibreOffice (OpenOffice's successor)!

Ok @Adam and @Kimvais were right, paramiko cannot parse .ppk files.

So the way to go (thanks to @JimB too) is to convert .ppk file to openssh private key format; this can be achieved using Puttygen as described here.

Then it's very simple getting connected with it:

import paramiko
ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect('<hostname>', username='<username>', password='<password>', key_filename='<path/to/openssh-private-key-file>')

stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
ssh.close()

Variables (something) are not valid JSON, verify using http://jsonlint.com/

I used this 457-55-5462 as testing SSN and it worked for me. I used it at paypal sandbox account. Hope it helps somebody

Here's a quick overview that explains the different build targets.

From my own experience, if you're looking to build a project that will run on both x86 and x64 platforms, and you don't have any specific x64 optimizations, I'd change the build to specifically say "x86."

The reason for this is sometimes you can get some DLL files that collide or some code that winds up crashing WoW in the x64 environment. By specifically specifying x86, the x64 OS will treat the application as a pure x86 application and make sure everything runs smoothly.

I think you can simply add the oneside option the book class?

i.e.

\documentclass[oneside]{book}

Although I didn't test it :)

Why don't you declare a string instead of writing a long lines into the layout file. For this you have to declare a line of code into layout file 'android:text="@string/text"' and go to the \\app\src\main\res\values\strings.xml and add a line of code ' Your multiline text here' Also use '\n' to break the line from any point else the line will automatically be adjusted.

pt is a derivation (abbreviation) of "point" which historically was used in print type faces where the size was commonly "measured" in "points" where 1 point has an approximate measurement of 1/72 of an inch, and thus a 72 point font would be 1 inch in size.

px is an abbreviation for "pixel" which is a simple "dot" on either a screen or a dot matrix printer or other printer or device which renders in a dot fashion - as opposed to old typewriters which had a fixed size, solid striker which left an imprint of the character by pressing on a ribbon, thus leaving an image of a fixed size.

Closely related to point are the terms "uppercase" and "lowercase" which historically had to do with the selection of the fixed typographical characters where the "captital" characters where placed in a box (case) above the non-captitalized characters which were place in a box below, and thus the "lower" case.

There were different boxes (cases) for different typographical fonts and sizes, but still and "upper" and "lower" case for each of those.

Another term is the "pica" which is a measure of one character in the font, thus a pica is 1/6 of an inch or 12 point units of measure (12/72) of measure.

Strickly speaking the measurement is on computers 4.233mm or 0.166in whereas the old point (American) is 1/72.27 of an inch and French is 4.512mm (0.177in.). Thus my statement of "approximate" regarding the measurements.

Further, typewriters as used in offices, had either and "Elite" or a "Pica" size where the size was 10 and 12 characters per inch repectivly.

Additionally, the "point", prior to standardization was based on the metal typographers "foot" size, the size of the basic footprint of one character, and varied somewhat in size.

Note that a typographical "foot" was originally from a deceased printers actual foot. A typographic foot contains 72 picas or 864 points.

As to CSS use, I prefer to use EM rather than px or pt, thus gaining the advantage of scaling without loss of relative location and size.

EDIT: Just for completeness you can think of EM (em) as an element of measure of one font height, thus 1em for a 12pt font would be the height of that font and 2em would be twice that height. Note that for a 12px font, 2em is 24 pixels. SO 10px is typically 0.63em of a standard font as "most" browsers base on 16px = 1em as a standard font size.

I am not using AnkhSVN but got a similar problem after cancelling a Tortoise SVN update. It left two directories "already locked". Similar to Roman C's solution. Use Get lock to to lock one file in each directory that is "already locked" and then release those locks, then do a cleanup on the highest directory. That seemed to fix the problem.

The top answer is useful but I expanded on it a bit.

If you want to set the value of your file object (the f in as f) based on the arguments passed to open() here's one way to do it:

def save_arg_return_data(*args, **kwargs):
    mm = MagicMock(spec=file)
    mm.__enter__.return_value = do_something_with_data(*args, **kwargs)
    return mm
m = MagicMock()
m.side_effect = save_arg_return_array_of_data

# if your open() call is in the file mymodule.animals 
# use mymodule.animals as name_of_called_file
open_name = '%s.open' % name_of_called_file

with patch(open_name, m, create=True):
    #do testing here

Basically, open() will return an object and with will call __enter__() on that object.

To mock properly, we must mock open() to return a mock object. That mock object should then mock the __enter__() call on it (MagicMock will do this for us) to return the mock data/file object we want (hence mm.__enter__.return_value). Doing this with 2 mocks the way above allows us to capture the arguments passed to open() and pass them to our do_something_with_data method.

I passed an entire mock file as a string to open() and my do_something_with_data looked like this:

def do_something_with_data(*args, **kwargs):
    return args[0].split("\n")

This transforms the string into a list so you can do the following as you would with a normal file:

for line in file:
    #do action

While not yet supported on iOS (as of iOS 10), websites can send push notifications to Firefox and Chrome (Desktop/Android) with the Push API.

The Push API is used in conjunction with the older Web Notifications to display the message. The advantage is that the Push API allow the notification to be delivered even when the user is not surfing your website, because they are built upon Service Workers (scripts that are registered by the browser and can be executed in background at a later time even after your user has left your website).

The process of sending a notification involves the following:

1. a user visits your website (must be secured over HTTPS): you ask permission to display push notifications and you register a service worker (a script that will be executed when a push notification is received)
2. if the user has granted permission, you can read the device token (endpoint) which should be sent to the server and stored
3. now you can send notifications to the user: your server makes an HTTP POST request to the endpoint (which is an URL that contains the device token). The server which receives the request is owned by the browser manufacturer (e.g. Google, Mozilla): the browser is constantly connected to it and can read the incoming notifications.
4. when the user browser receives a notification executes the service worker, which is responsible for managing the event, retrieving the notification data from the server and displaying the notification to the user

The Push API is currently supported on desktop and Android by Chrome, Firefox and Opera.

You can also send push notifications to Apple / Safari desktop using APNs. The approach is similar, but with many complications (apple developer certificates, push packages, low-level TCP connection to APNs).

If you want to implement the push notifications by yourself start with these tutorials:

• Push API: Push Notifications on the Open Web
• Apple Push Notification system: Configuring Safari Push Notifications

If you are looking for a drop in solution I would suggest Pushpad, which is a service I have built.

Update (September 2017): Apple has started developing the service workers for WebKit (status). Since the service workers are a fundamental technology for web push, this is a big step forward.

If you use jQuery, you can do something like that :

$(document).ready(function(){$("input.autocompleteOff").attr("autocomplete","off");});

and use the autocompleteOff class where you want :

<input type="text" name="fieldName" id="fieldId" class="firstCSSClass otherCSSClass autocompleteOff" />

If you want ALL your input to be autocomplete=off, you can simply use that :

$(document).ready(function(){$("input").attr("autocomplete","off");});

Not best answer but you can reuse an already created ca bundle using --cert option of pip, for instance:

pip install SQLAlchemy==1.1.15 --cert="C:\Users\myUser\certificates\my_ca-bundle.crt"

Just to clarify, in your 3rd example _myProperty isn't actually a property. It's a field with get and set methods (and as has already been mentioned the get and set methods should specify return types).

In C# the 3rd method should be avoided in most situations. You'd only really use it if the type you wanted to return was an array, or if the get method did a lot of work rather than just returning a value. The latter isn't really necessary but for the purpose of clarity a property's get method that does a lot of work is misleading.

Drop you database, then it will work.

You can perform the following steps to drop your database

step 1 : Go to mongodb installation directory, default dir is "C:\Program Files\MongoDB\Server\4.2\bin"

step 2 : Start mongod.exe directly or using command prompt and minimize it.

step 3 : Start mongo.exe directly or using command prompt and run the following command

i) use yourDatabaseName (use show databases if you don't remember database name)

ii) db.dropDatabase()

This will remove your database. Now you can insert your data, it won't show error, it will automatically add database and collection.

ALL YOU HAVE TO DO:

HTML:

<table id="my-table"><tr>
<td> CELL 1 With a lot of text in it</td>
<td> CELL 2 </td>
<td> CELL 3 </td>
<td> CELL 4 With a lot of text in it </td>
<td> CELL 5 </td>
</tr></table>

CSS:

#my-table{width:100%;} /*or whatever width you want*/
#my-table td{width:2000px;} /*something big*/

if you have th you need to set it too like this:

#my-table th{width:2000px;}

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

I had this problem where I couldn't unlock a file from the client side. I decided to go to the sever side which was much simpler.

On SVN Server:

Locate locks

 svnadmin lslocks /root/of/repo
 (in my case it was var/www/svn/[name of Company])

 You can add a specific path to this by svnadmin lslocks /root/of/repo "path/to/file"

Remove lock

 svnadmin rmlocks /root/of/repo “path/to/file” 

That's it!

You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.

SELECT * FROM <table_name> WHERE id = 1 
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';

If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':

hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')

The examples to os.walk in the documentation show how to do this:

for root, dirs, filenames in os.walk(indir):
    for f in filenames:
        log = open(os.path.join(root, f),'r')

How did you expect the "open" function to know that the string "1" is supposed to mean "/home/des/test/1" (unless "/home/des/test" happens to be your current working directory)?

1. Install the http-server, running command npm install http-server -g
2. Open the terminal in the path where is located the index.html
3. Run command http-server . -o
4. Enjoy it!

I hope this is what you are looking for.

class Try:
    def do_somthing(self):
        print 'Hello'

if __name__ == '__main__':
    obj_list = []
    for obj in range(10):
        obj = Try()
        obj_list.append(obj)

    obj_list[0].do_somthing()

Output:

Hello

I might be wrong but "find -name __" works fine for me. (Maybe it's just my phone.) If you just want to list all files, you can try

adb shell ls -R /

You probably need the root permission though.

Edit: As other answers suggest, use ls with grep like this:

adb shell ls -Ral yourDirectory | grep -i yourString

eg.

adb shell ls -Ral / | grep -i myfile

-i is for ignore-case. and / is the root directory.

(This answer has been updated to match SVN 1.8 and 1.9's behaviour)

You have 2 questions:

Marking files as ignored:

By "ignored file" I mean the file won't appear in lists even as "unversioned": your SVN client will pretend the file doesn't exist at all in the filesystem.

Ignored files are specified by a "file pattern". The syntax and format of file patterns is explained in SVN's online documentation: http://svnbook.red-bean.com/nightly/en/svn.advanced.props.special.ignore.html "File Patterns in Subversion".

Subversion, as of version 1.8 (June 2013) and later, supports 3 different ways of specifying file patterns. Here's a summary with examples:

1 - Runtime Configuration Area - global-ignores option:

• This is a client-side only setting, so your global-ignores list won't be shared by other users, and it applies to all repos you checkout onto your computer.
• This setting is defined in your Runtime Configuration Area file:
  • Windows (file-based) - C:\Users\{you}\AppData\Roaming\Subversion\config
  • Windows (registry-based) - Software\Tigris.org\Subversion\Config\Miscellany\global-ignores in both HKLM and HKCU.
  • Linux/Unix - ~/.subversion/config

2 - The svn:ignore property, which is set on directories (not files):

• This is stored within the repo, so other users will have the same ignore files. Similar to how .gitignore works.
• svn:ignore is applied to directories and is non-recursive or inherited. Any file or immediate subdirectory of the parent directory that matches the File Pattern will be excluded.

• While SVN 1.8 adds the concept of "inherited properties", the svn:ignore property itself is ignored in non-immediate descendant directories:

  cd ~/myRepoRoot                             # Open an existing repo.
  echo "foo" > "ignoreThis.txt"                # Create a file called "ignoreThis.txt".
  
  svn status                                  # Check to see if the file is ignored or not.
  > ?    ./ignoreThis.txt
  > 1 unversioned file                        # ...it is NOT currently ignored.
  
  svn propset svn:ignore "ignoreThis.txt" .   # Apply the svn:ignore property to the "myRepoRoot" directory.
  svn status
  > 0 unversioned files                       # ...but now the file is ignored!
  
  cd subdirectory                             # now open a subdirectory.
  echo "foo" > "ignoreThis.txt"                # create another file named "ignoreThis.txt".
  
  svn status
  > ?    ./subdirectory/ignoreThis.txt        # ...and is is NOT ignored!
  > 1 unversioned file
  

  (So the file ./subdirectory/ignoreThis is not ignored, even though "ignoreThis.txt" is applied on the . repo root).

• Therefore, to apply an ignore list recursively you must use svn propset svn:ignore <filePattern> . --recursive.

  • This will create a copy of the property on every subdirectory.
  • If the <filePattern> value is different in a child directory then the child's value completely overrides the parents, so there is no "additive" effect.
  • So if you change the <filePattern> on the root ., then you must change it with --recursive to overwrite it on the child and descendant directories.

• I note that the command-line syntax is counter-intuitive.

  • I started-off assuming that you would ignore a file in SVN by typing something like svn ignore pathToFileToIgnore.txt however this is not how SVN's ignore feature works.

3- The svn:global-ignores property. Requires SVN 1.8 (June 2013):

• This is similar to svn:ignore, except it makes use of SVN 1.8's "inherited properties" feature.
• Compare to svn:ignore, the file pattern is automatically applied in every descendant directory (not just immediate children).
  • This means that is unnecessary to set svn:global-ignores with the --recursive flag, as inherited ignore file patterns are automatically applied as they're inherited.

• Running the same set of commands as in the previous example, but using svn:global-ignores instead:

  cd ~/myRepoRoot                                    # Open an existing repo
  echo "foo" > "ignoreThis.txt"                       # Create a file called "ignoreThis.txt"
  svn status                                         # Check to see if the file is ignored or not
  > ?    ./ignoreThis.txt
  > 1 unversioned file                               # ...it is NOT currently ignored
  
  svn propset svn:global-ignores "ignoreThis.txt" .
  svn status
  > 0 unversioned files                              # ...but now the file is ignored!
  
  cd subdirectory                                    # now open a subdirectory
  echo "foo" > "ignoreThis.txt"                       # create another file named "ignoreThis.txt"
  svn status
  > 0 unversioned files                              # the file is ignored here too!
  

For TortoiseSVN users:

This whole arrangement was confusing for me, because TortoiseSVN's terminology (as used in their Windows Explorer menu system) was initially misleading to me - I was unsure what the significance of the Ignore menu's "Add recursively", "Add *" and "Add " options. I hope this post explains how the Ignore feature ties-in to the SVN Properties feature. That said, I suggest using the command-line to set ignored files so you get a feel for how it works instead of using the GUI, and only using the GUI to manipulate properties after you're comfortable with the command-line.

Listing files that are ignored:

The command svn status will hide ignored files (that is, files that match an RGA global-ignores pattern, or match an immediate parent directory's svn:ignore pattern or match any ancesor directory's svn:global-ignores pattern.

Use the --no-ignore option to see those files listed. Ignored files have a status of I, then pipe the output to grep to only show lines starting with "I".

The command is:

svn status --no-ignore | grep "^I"

For example:

svn status
> ? foo                             # An unversioned file
> M modifiedFile.txt                # A versioned file that has been modified

svn status --no-ignore
> ? foo                             # An unversioned file
> I ignoreThis.txt                  # A file matching an svn:ignore pattern
> M modifiedFile.txt                # A versioned file that has been modified

svn status --no-ignore | grep "^I"
> I ignoreThis.txt                  # A file matching an svn:ignore pattern

ta-da!

const is similar to static we can access both varables with class name but diff is static variables can be modified and const can not.

Perhaps you may want to consider doing a SELECT max(Id) - min(Id) + 1. This will only work if your Ids are sequential and rows are not deleted. It is however very fast.

Starting in Python 2.6, there is an alternative: the str.format() method. Here are some examples using the existing string format operator (%):

>>> "Name: %s, age: %d" % ('John', 35) 
'Name: John, age: 35' 
>>> i = 45 
>>> 'dec: %d/oct: %#o/hex: %#X' % (i, i, i) 
'dec: 45/oct: 055/hex: 0X2D' 
>>> "MM/DD/YY = %02d/%02d/%02d" % (12, 7, 41) 
'MM/DD/YY = 12/07/41' 
>>> 'Total with tax: $%.2f' % (13.00 * 1.0825) 
'Total with tax: $14.07' 
>>> d = {'web': 'user', 'page': 42} 
>>> 'http://xxx.yyy.zzz/%(web)s/%(page)d.html' % d 
'http://xxx.yyy.zzz/user/42.html' 

Here are the equivalent snippets but using str.format():

>>> "Name: {0}, age: {1}".format('John', 35) 
'Name: John, age: 35' 
>>> i = 45 
>>> 'dec: {0}/oct: {0:#o}/hex: {0:#X}'.format(i) 
'dec: 45/oct: 0o55/hex: 0X2D' 
>>> "MM/DD/YY = {0:02d}/{1:02d}/{2:02d}".format(12, 7, 41) 
'MM/DD/YY = 12/07/41' 
>>> 'Total with tax: ${0:.2f}'.format(13.00 * 1.0825) 
'Total with tax: $14.07' 
>>> d = {'web': 'user', 'page': 42} 
>>> 'http://xxx.yyy.zzz/{web}/{page}.html'.format(**d) 
'http://xxx.yyy.zzz/user/42.html'

Like Python 2.6+, all Python 3 releases (so far) understand how to do both. I shamelessly ripped this stuff straight out of my hardcore Python intro book and the slides for the Intro+Intermediate Python courses I offer from time-to-time. :-)

Aug 2018 UPDATE: Of course, now that we have the f-string feature in 3.6, we need the equivalent examples of that, yes another alternative:

>>> name, age = 'John', 35
>>> f'Name: {name}, age: {age}'
'Name: John, age: 35'

>>> i = 45
>>> f'dec: {i}/oct: {i:#o}/hex: {i:#X}'
'dec: 45/oct: 0o55/hex: 0X2D'

>>> m, d, y = 12, 7, 41
>>> f"MM/DD/YY = {m:02d}/{d:02d}/{y:02d}"
'MM/DD/YY = 12/07/41'

>>> f'Total with tax: ${13.00 * 1.0825:.2f}'
'Total with tax: $14.07'

>>> d = {'web': 'user', 'page': 42}

Two years after my first go, I'm recidivating...

Why do we prefer parameters? SQL injection is obviously a big reason, but could it be that we're secretly longing to get back to SQL as a language. SQL in string literals is already a weird cultural practice, but at least you can copy and paste your request into management studio. SQL dynamically constructed with host language conditionals and control structures, when SQL has conditionals and control structures, is just level 0 barbarism. You have to run your app in debug, or with a trace, to see what SQL it generates.

Don't stop with just parameters. Go all the way and use QueryFirst (disclaimer: which I wrote). Your SQL lives in a .sql file. You edit it in the fabulous TSQL editor window, with syntax validation and Intellisense for your tables and columns. You can assign test data in the special comments section and click "play" to run your query right there in the window. Creating a parameter is as easy as putting "@myParam" in your SQL. Then, each time you save, QueryFirst generates the C# wrapper for your query. Your parameters pop up, strongly typed, as arguments to the Execute() methods. Your results are returned in an IEnumerable or List of strongly typed POCOs, the types generated from the actual schema returned by your query. If your query doesn't run, your app won't compile. If your db schema changes and your query runs but some columns disappear, the compile error points to the line in your code that tries to access the missing data. And there are numerous other advantages. Why would you want to access data any other way?

Map<String,Choice> map=list.stream().collect(Collectors.toMap(Choice::getName, s->s));

Even serves this purpose for me,

Map<String,Choice> map=  list1.stream().collect(()-> new HashMap<String,Choice>(), 
            (r,s) -> r.put(s.getString(),s),(r,s) -> r.putAll(s));

Most basic regex is following:

(^([0-9A-Fa-f]{8}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{12})$) 

or you could paste it here.

Hope this saves you some time.

When we use crontab or the deprecated /etc/rc.local file, we need a delay (e.g. sleep 10, depending on the machine) to make sure that system services are available. Usually, systemd (or upstart) is used to manage which services start when the system boots. You can try use the similar configuration for this:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up -d
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

Or, if you want run without the -d flag:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0
Restart=on-failure
StartLimitIntervalSec=60
StartLimitBurst=3

[Install]
WantedBy=multi-user.target

Change the WorkingDirectory parameter with your dockerized project path. And enable the service to start automatically:

systemctl enable docker-compose-app

I have came across the very-very-same problem.

In short:

• Willing to have original CSS in an "internal" dir (Resources/assets/css/a.css)
• Willing to have the images in the "public" dir (Resources/public/images/devil.png)
• Willing that twig takes that CSS, recompiles it into web/css/a.css and make it point the image in /web/bundles/mynicebundle/images/devil.png

I have made a test with ALL possible (sane) combinations of the following:

• @notation, relative notation
• Parse with cssrewrite, without it
• CSS image background vs direct <img> tag src= to the very same image than CSS
• CSS parsed with assetic and also without parsing with assetic direct output
• And all this multiplied by trying a "public dir" (as Resources/public/css) with the CSS and a "private" directory (as Resources/assets/css).

This gave me a total of 14 combinations on the same twig, and this route was launched from

• "/app_dev.php/"
• "/app.php/"
• and "/"

thus giving 14 x 3 = 42 tests.

Additionally, all this has been tested working in a subdirectory, so there is no way to fool by giving absolute URLs because they would simply not work.

The tests were two unnamed images and then divs named from 'a' to 'f' for the CSS built FROM the public folder and named 'g to 'l' for the ones built from the internal path.

I observed the following:

Only 3 of the 14 tests were shown adequately on the three URLs. And NONE was from the "internal" folder (Resources/assets). It was a pre-requisite to have the spare CSS PUBLIC and then build with assetic FROM there.

These are the results:

1. Result launched with /app_dev.php/

2. Result launched with /app.php/

3. Result launched with /

So... ONLY - The second image - Div B - Div C are the allowed syntaxes.

Here there is the TWIG code:

All this came, because I did not want the individual original files exposed to the public, specially if I wanted to play with "less" filter or "sass" or similar... I did not want my "originals" published, only the compiled one.

But there are good news. If you don't want to have the "spare CSS" in the public directories... install them not with --symlink, but really making a copy. Once "assetic" has built the compound CSS, and you can DELETE the original CSS from the filesystem, and leave the images:

Compilation process

Note I do this for the --env=prod environment.

Just a few final thoughts:

• This desired behaviour can be achieved by having the images in "public" directory in Git or Mercurial and the "css" in the "assets" directory. That is, instead of having them in "public" as shown in the directories, imagine a, b, c... residing in the "assets" instead of "public", than have your installer/deployer (probably a Bash script) to put the CSS temporarily inside the "public" dir before assets:install is executed, then assets:install, then assetic:dump, and then automating the removal of CSS from the public directory after assetic:dump has been executed. This would achive EXACTLY the behaviour desired in the question.

• Another (unknown if possible) solution would be to explore if "assets:install" can only take "public" as the source or could also take "assets" as a source to publish. That would help when installed with the --symlink option when developing.

• Additionally, if we are going to script the removal from the "public" dir, then, the need of storing them in a separate directory ("assets") disappears. They can live inside "public" in our version-control system as there will be dropped upon deploy to the public. This allows also for the --symlink usage.

BUT ANYWAY, CAUTION NOW: As now the originals are not there anymore (rm -Rf), there are only two solutions, not three. The working div "B" does not work anymore as it was an asset() call assuming there was the original asset. Only "C" (the compiled one) will work.

So... there is ONLY a FINAL WINNER: Div "C" allows EXACTLY what it was asked in the topic: To be compiled, respect the path to the images and do not expose the original source to the public.

The winner is C

Store all the to be deleted ID's into a table. Then there are 3 ways. 1) loop through all the ID's in the table, then delete one row at a time for X commit interval. X can be a 100 or 1000. It works on OLTP environment and you can control the locks.

2) Use Oracle Bulk Delete

3) Use correlated delete query.

Single query is usually faster than multiple queries because of less context switching, and possibly less parsing.

You can use scriptlets, however, this is not the way to go. Nowdays inline scriplets or JAVA code in your JSP files is considered a bad habit.

You should read up on JSTL a bit more. If the ansokanInfo object is in your request or session scope, printing the object (toString() method) like this: ${ansokanInfo} can give you some base information. ${ansokanInfo.pSystem} should call the object getter method. If this all works, you can use this:

<c:if test="${ ansokanInfo.pSystem  == 'NAT'}"> tataa </c:if>

To complete Wiktor Stribizew and Dougui answers I would say that /regex/.match?("string") about as fast as "string".match?(/regex/).

check this: https://github.com/luciotato/waitfor-ES6

your code with wait.for: (requires generators, --harmony flag)

function* (query) {
  var r = yield wait.for( myApi.exec, 'SomeCommand');
  return r;
}

The problem you have is that you're attempting to bind the "test" class to the event before there is anything with a "test" class in the DOM. Although it may seem like this is all dynamic, what is really happening is JQuery makes a pass over the DOM and wires up the click event when the ready() function fired, which happens before you created the "Click Me" in your button event.

By adding the "test" Click event to the "button" click handler it will wire it up after the correct element exists in the DOM.

<script type="text/javascript">
    $(document).ready(function(){                          
        $("button").click(function(){                                  
            $("h2").html("<p class='test'>click me</p>")                          
            $(".test").click(function(){                          
                alert()                          
            });       
        });                                     
    });
</script>

Using live() (as others have pointed out) is another way to do this but I felt it was also a good idea to point out the minor error in your JS code. What you wrote wasn't wrong, it just needed to be correctly scoped. Grasping how the DOM and JS works is one of the tricky things for many traditional developers to wrap their head around.

live() is a cleaner way to handle this and in most cases is the correct way to go. It essentially is watching the DOM and re-wiring things whenever the elements within it change.

Doing type('') is effectively equivalent to str and types.StringType

so type('') == str == types.StringType will evaluate to "True"

Note that Unicode strings which only contain ASCII will fail if checking types in this way, so you may want to do something like assert type(s) in (str, unicode) or assert isinstance(obj, basestring), the latter of which was suggested in the comments by 007Brendan and is probably preferred.

isinstance() is useful if you want to ask whether an object is an instance of a class, e.g:

class MyClass: pass

print isinstance(MyClass(), MyClass) # -> True
print isinstance(MyClass, MyClass()) # -> TypeError exception

But for basic types, e.g. str, unicode, int, float, long etc asking type(var) == TYPE will work OK.

If that message is bother you, You need run Visual Studio with administrative rights to apply this direction on Visual Studio.

Tools-> Options-> Debugging-> Symbols and select check in a box "Microsoft Symbol Servers", mark load all modules then click Load all Symbols.

Everything else Visual Studio will do it for you, and you will have this message under Debug in Output window "Native' has exited with code 0 (0x0)"

Let's say you have this image:

to make a circle out of this you only need to add

.circle {
  border-radius: 50%;
  width: 100px;
  height: 100px; 
}

So if you have a div you can do the same thing.

Check the example below:

.circle {_x000D_
  border-radius: 50%;_x000D_
  width: 100px;_x000D_
  height: 100px; _x000D_

    transform: rotate(0deg);_x000D_
  }_x000D_
  to {_x000D_

"How do I do that? I explored PHPMyAdmin, and I can't find a "change engine" functionality."

In direct response to this part of your question, you can issue an ALTER TABLE tbl engine=InnoDB; and it'll recreate the table in the proper engine.

Try to consider following image

For example Object.MemberwiseClone creates a shallow copy link

and using ICloneable interface you can get deep copy as described here

Not need to change all config in file /opt/lampp/etc/extra/httpd-xampp.conf. The only thing you need to change is the Require local It's kinda obvious what Require local means so just change to Require all granted Require all granted

Solution

from Require local to Require all granted

You can always create an array of pointers , pointing to car objects and then create objects, in a for loop, as you want and save their address in the array , for example :

#include <iostream>
class Car
{
private:
  Car(){};
  int _no;
public:
  Car(int no)
  {
    _no=no;
  }
  void printNo()
  {
    std::cout<<_no<<std::endl;
  }
};
void printCarNumbers(Car *cars, int length)
{
    for(int i = 0; i<length;i++)
         std::cout<<cars[i].printNo();
}

int main()
{
  int userInput = 10;
  Car **mycars = new Car*[userInput];
  int i;
  for(i=0;i<userInput;i++)
      mycars[i] = new Car(i+1);

note new method !!!

  printCarNumbers_new(mycars,userInput);


  return 0;
}    

All you have to change in new method is handling cars as pointers than static objects in parameter and when calling method printNo() for example :

void printCarNumbers_new(Car **cars, int length)
{
    for(int i = 0; i<length;i++)
         std::cout<<cars[i]->printNo();
}

at the end of main is good to delete all dynamicly allocated memory like this

for(i=0;i<userInput;i++)
  delete mycars[i];      //deleting one obgject
delete[] mycars;         //deleting array of objects

Hope I helped, cheers!

This happens generally when you try access another domain's resources.

This is a security feature for avoiding everyone freely accessing any resources of that domain (which can be accessed for example to have an exact same copy of your website on a pirate domain).

The header of the response, even if it's 200OK do not allow other origins (domains, port) to access the ressources.

You can fix this problem if you are the owner of both domains:

Solution 1: via .htaccess

To change that, you can write this in the .htaccess of the requested domain file:

    <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
    </IfModule>

If you only want to give access to one domain, the .htaccess should look like this:

    <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin 'https://my-domain.tdl'
    </IfModule>

Solution 2: set headers the correct way

If you set this into the response header of the requested file, you will allow everyone to access the ressources:

Access-Control-Allow-Origin : *

OR

Access-Control-Allow-Origin : http://www.my-domain.com

Peace and code ;)

Set id for the textbox. ie,

<input type="text" name="txtJob" value="software engineer" id="txtJob"> 

In javascript

var jobValue = document.getElementById('txtJob').value

In Jquery

 var jobValue =  $("#txtJob").val();

It may be obvious but, by stating the Range and not including which workbook or worksheet then it may be trying to CountA() on a different sheet entirely. I find to fully address these things saves a lot of headaches.

Resolution fix: For me, the problem was related to active chrome sessions. I closed all of my chrome browser sessions and then tried building to chrome again. I am using Visual Studio Professional 2017 version 15.3.2. The VS application I was running into build errors with was a WebAPI project. When trying to click the green play button, I was getting dialog error stating "Unable to start the program 'http://localhost:18980/'. An operation is not legal in the current state. Hopefully this post helps someone.

While the suggested solution works fine, there is another way to return a byte array from the controller, with response stream properly formatted :

• In the request, set header "Accept: application/octet-stream".
• Server-side, add a media type formatter to support this mime type.

Unfortunately, WebApi does not include any formatter for "application/octet-stream". There is an implementation here on GitHub: BinaryMediaTypeFormatter (there are minor adaptations to make it work for webapi 2, method signatures changed).

You can add this formatter into your global config :

HttpConfiguration config;
// ...
config.Formatters.Add(new BinaryMediaTypeFormatter(false));

WebApi should now use BinaryMediaTypeFormatter if the request specifies the correct Accept header.

I prefer this solution because an action controller returning byte[] is more comfortable to test. Though, the other solution allows you more control if you want to return another content-type than "application/octet-stream" (for example "image/gif").

You can use ApplicationContextAware.

ApplicationContextAware:

Interface to be implemented by any object that wishes to be notified of the ApplicationContext that it runs in. Implementing this interface makes sense for example when an object requires access to a set of collaborating beans.

There are a few methods for obtaining a reference to the application context. You can implement ApplicationContextAware as in the following example:

package hello;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
 
@Component
public class ApplicationContextProvider implements ApplicationContextAware {

    private ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    } 

 public ApplicationContext getContext() {
        return applicationContext;
    }
    
}

Update:

When Spring instantiates beans, it looks for ApplicationContextAware implementations, If they are found, the setApplicationContext() methods will be invoked.

In this way, Spring is setting current applicationcontext.

Code snippet from Spring's source code:

private void invokeAwareInterfaces(Object bean) {
        .....
        .....
 if (bean instanceof ApplicationContextAware) {                
  ((ApplicationContextAware)bean).setApplicationContext(this.applicationContext);
   }
}

Once you get the reference to Application context, you get fetch the bean whichever you want by using getBean().

To convert the data to a MySQL database, you can use the Bullzip Access to MySQL program. It's free and easy to use.

Apply float:left; to both of your divs should make them stand side by side.

If you are writing a module in your own code for a specific usage, majkinetor's method MIGHT have worked. But there are some problems.

First, the official document does NOT guarantee that the GetHashCode() returns an unique identifier (see Object.GetHashCode Method ()):

You should not assume that equal hash codes imply object equality.

Second, assume you have a very small amount of objects so that GetHashCode() will work in most cases, this method can be overridden by some types.
For example, you are using some class C and it overrides GetHashCode() to always return 0. Then every object of C will get the same hash code. Unfortunately, Dictionary, HashTable and some other associative containers will make use this method:

A hash code is a numeric value that is used to insert and identify an object in a hash-based collection such as the Dictionary<TKey, TValue> class, the Hashtable class, or a type derived from the DictionaryBase class. The GetHashCode method provides this hash code for algorithms that need quick checks of object equality.

So, this approach has great limitations.

And even more, what if you want to build a general purpose library? Not only are you not able to modify the source code of the used classes, but their behavior is also unpredictable.

I appreciate that Jon and Simon have posted their answers, and I will post a code example and a suggestion on performance below.

}

In my test, the ObjectIDGenerator will throw an exception to complain that there are too many objects when creating 10,000,000 objects (10x than in the code above) in the for loop.

Also, the benchmark result is that the ConditionalWeakTable implementation is 1.8x faster than the ObjectIDGenerator implementation.

You can also use a "here document" to do the same thing:

I tried the above and had issues with the amount of data that my 20MB Excel I needed to convert consisted of; therefore the above did not work for me.

After more research I stumbled upon openxlsx and this one finally did the trick (and fast) Importing a big xlsx file into R?

https://cran.r-project.org/web/packages/openxlsx/openxlsx.pdf

It's perfectly OK doing it that way, but unless you need to use a closure or return the function I'd probably put in the module level. I imagine in the second code example you mean:

...
some_data = method_b() # not some_data = method_b

otherwise, some_data will be the function.

Having it at the module level will allow other functions to use method_b() and if you're using something like Sphinx (and autodoc) for documentation, it will allow you to document method_b as well.

You also may want to consider just putting the functionality in two methods in a class if you're doing something that can be representable by an object. This contains logic well too if that's all you're looking for.

It seems you (and/or your company) have a fundamental misunderstanding of what a family tree is supposed to be.

Let me clarify, I also work for a company that has (as one of its products) a family tree in its portfolio, and we have been struggling with similar problems.

The problem, in our case, and I assume your case as well, comes from the GEDCOM format that is extremely opinionated about what a family should be. However this format contains some severe misconceptions about what a family tree really looks like.

GEDCOM has many issues, such as incompatibility with same sex relations, incest, etc... Which in real life happens more often than you'd imagine (especially when going back in time to the 1700-1800).

We have modeled our family tree to what happens in the real world: Events (for example, births, weddings, engagement, unions, deaths, adoptions, etc.). We do not put any restrictions on these, except for logically impossible ones (for example, one can't be one's own parent, relations need two individuals, etc...)

The lack of validations gives us a more "real world", simpler and more flexible solution.

As for this specific case, I would suggest removing the assertions as they do not hold universally.

For displaying issues (that will arise) I would suggest drawing the same node as many times as needed, hinting at the duplication by lighting up all the copies on selecting one of them.

There is an issue that if you close the dialog it will execute the onCloseCallback function. This is a better design.

function jAlert2(outputMsg, titleMsg, onCloseCallback) {
    if (!titleMsg)
        titleMsg = 'Alert';

    if (!outputMsg)
        outputMsg = 'No Message to Display.';

    $("<div></div>").html(outputMsg).dialog({
        title: titleMsg,
        resizable: false,
        modal: true,
        buttons: {
            "OK": onCloseCallback,
            "Cancel": function() {
          $( this ).dialog( "destroy" );
            }

        },
    });

With applescript:

tell application "Firefox" to activate

That worked for me

GO111MODULE=on go get -u github.com/segmentio/[email protected]

Would that work for you?

public class Main {

public static void main(String[] args) {
    Random r = new Random(System.currentTimeMillis());
    System.out.println(r.nextInt(100000) * 0.000001);
}

}

result e.g. 0.019007

In short, it happens when the application which writes to the sqlite database does not have write permission.

This can be solved in three ways:

1. Granting ownership of db.sqlite3 file and its parent directory (thereby write access also) to the user using chown (Eg: chown username db.sqlite3 )
2. Running the webserver (often gunicorn) as root user (run the command sudo -i before you run gunicorn or django runserver)
3. Allowing read and write access to all users by running command chmod 777 db.sqlite3 (Dangerous option)

Never go for the third option unless you are running the webserver in a local machine or the data in the database is not at all important for you.

Second option is also not recommended. But you can go for it, if you are sure that your application is not vulnerable for code injection attack.

You need to read from req.Body. The ParseForm method is reading from the req.Body and then parsing it in standard HTTP encoded format. What you want is to read the body and parse it in JSON format.

Here's your code updated.

package main

import (
    "encoding/json"
    "log"
    "net/http"
    "io/ioutil"
)

type test_struct struct {
    Test string
}

func test(rw http.ResponseWriter, req *http.Request) {
    body, err := ioutil.ReadAll(req.Body)
    if err != nil {
        panic(err)
    }
    log.Println(string(body))
    var t test_struct
    err = json.Unmarshal(body, &t)
    if err != nil {
        panic(err)
    }
    log.Println(t.Test)
}

func main() {
    http.HandleFunc("/test", test)
    log.Fatal(http.ListenAndServe(":8082", nil))
}

Try (maybe as root)

lsof -i -P

and grep the output for the port you are looking for.

For example to check for port 80 do

lsof -i -P | grep :80

Git itself has no provision to specify the repository name. The root directory's name is the single source of truth pertaining to the repository name.

The .git/description though is used only by some applications, like GitWeb.

Since you are using Access to compose the query, you have to stick to Access's version of SQL.

To choose between several different return values, use the switch() function. So to translate and extend your example a bit:

select switch(
  age > 40, 4,
  age > 25, 3,
  age > 20, 2,
  age > 10, 1,
  true, 0
) from demo

The 'true' case is the default one. If you don't have it and none of the other cases match, the function will return null.

The Office website has documentation on this but their example syntax is VBA and it's also wrong. I've given them feedback on this but you should be fine following the above example.

I tried using React.FormEvent<HTMLSelectElement> but it led to an error in the editor, even though there is no EventTarget visible in the code:

The property 'value' does not exist on value of type 'EventTarget'

Then I changed React.FormEvent to React.ChangeEvent and it helped:

private changeName(event: React.ChangeEvent<HTMLSelectElement>) {
    event.preventDefault();
    this.props.actions.changeName(event.target.value);
}

android.R.id.custom was returning null for me. I managed to get this to work in case anybody comes across the same issue,

AlertDialog.Builder builder = new AlertDialog.Builder(context)
            .setTitle("My title")
            .setMessage("Enter password");
final FrameLayout frameView = new FrameLayout(context);
builder.setView(frameView);

final AlertDialog alertDialog = builder.create();
LayoutInflater inflater = alertDialog.getLayoutInflater();
View dialoglayout = inflater.inflate(R.layout.simple_password, frameView);
alertDialog.show();

For reference, R.layout.simple_password is :

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

<EditText
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/password_edit_view"
        android:inputType="textPassword"/>
<CheckBox
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/show_password"
        android:id="@+id/show_password_checkbox"
        android:layout_gravity="left|center_vertical"
        android:checked="false"/>

Two ways to stop running a container:

1. $docker stop container_ID

2. $docker kill container_ID

You can get running containers using the following command:

$docker ps

Following links for more information:

• https://docs.docker.com/engine/reference/commandline/stop/
• https://docs.docker.com/v1.8/reference/commandline/kill/

a quick way to see your errors whilst testing:

$error= $st->errorInfo();
echo $error[2];

This worked for me:

insert into table1 select * from table2

The sentence is a bit different from Oracle's.

Install Qt

sudo apt-get install build-essential

sudo apt-get install qtcreator

sudo apt-get install qt5-default

Install documentation and examples If Qt Creator is installed thanks to the Ubuntu Sofware Center or thanks to the synaptic package manager, documentation for Qt Creator is not installed. Hitting the F1 key will show you the following message : "No documentation available". This can easily be solved by installing the Qt documentation:

sudo apt-get install qt5-doc

sudo apt-get install qt5-doc-html qtbase5-doc-html

sudo apt-get install qtbase5-examples

Restart Qt Creator to make the documentation available.

ModelSim-Altera error

It looks like you are trying to parse each line. You've been shown by another answer how to use getline in a loop to seperate each line. The other tool you are going to want is istringstream, to seperate each token.

std::string line;
while(std::getline(file, line))
{
    std::istringstream iss(line);
    std::string token;
    while (iss >> token)
    {
        // do something with token
    }
}

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

If you don't know the host branch, make this:

git submodule foreach git pull origin $(git rev-parse --abbrev-ref HEAD)

It will get a branch of the main Git repository and then for each submodule will make a pull of the same branch.

I ran into this very issue today morning and found the solution for it too. This issue is created when you have messed up one of your .xml files. I'll suggest you go through them one by one and look for recent changes made. It might be caused by a silly mistake.

In my case, I accidentally hardcoded a color string as #FFFFF(Bad practice, I know). As you can see it had 5 F instead of 6. It didn't show any warning but was the root of the same issue as encountered by you.

Edit 1: Another thing you can do is to run assembleDebug in your gradle console. It will find the specific line for you.

Edit 2: Adding an image for reference to run assembleDebug.

The (+) operator indicates an outer join. This means that Oracle will still return records from the other side of the join even when there is no match. For example if a and b are emp and dept and you can have employees unassigned to a department then the following statement will return details of all employees whether or not they've been assigned to a department.

select * from emp, dept where emp.dept_id=dept.dept_id(+)

So in short, removing the (+) may make a significance difference but you might not notice for a while depending on your data!

You can use the pluck method:

Word_relation::where('word_one', $word_id)->pluck('word_two')->toArray();

For more info on what methods are available for using with collection, you can you can check out the Laravel Documentation.

Not really and I am talking about SQL Server. The temp table (with single #) exists and is visible within the scope it is created (scope-bound). Each time you call your stored procedure it creates a new scope and therefore that temp table exists only in that scope. I believe the temp tables are also visible to stored procedures and udfs that're called within that scope as well. If you however use double pound (##) then they become global within your session and therefore visible to other executing processes as part of the session that the temp table is created in and you will have to think if the possibility of temp table being accessed concurrently is desirable or not.

You can add any type of HTML with methods like append and appendTo (among others):

$('form#someform').append('<input type="text" name="something" id="something" />');

Reasons of ignoring these argument is permanent generation has been removed in HotSpot for JDK8 because of following drawbacks

• Fixed size at startup – difficult to tune.
• Internal Hotspot types were Java objects : Could move with full GC, opaque, not strongly typed and hard to debug, needed meta-metadata.
• Simplify full collections : Special iterators for metadata for each collector
• Want to deallocate class data concurrently and not during GC pause
• Enable future improvements that were limited by PermGen.

The Permanent Generation (PermGen) space has completely been removed and is kind of replaced by a new space called Metaspace. The consequences of the PermGen removal is that obviously the PermSize and MaxPermSize JVM arguments are ignored and you will never get a java.lang.OutOfMemoryError: PermGen error.

Advantages of MetaSpace

• Take advantage of Java Language Specification property : Classes and associated metadata lifetimes match class loader’s
• Per loader storage area – Metaspace
• Linear allocation only
• No individual reclamation (except for RedefineClasses and class loading failure)
• No GC scan or compaction
• No relocation for metaspace objects

Metaspace Tuning

The maximum metaspace size can be set using the -XX:MaxMetaspaceSize flag, and the default is unlimited, which means that only your system memory is the limit. The -XX:MetaspaceSize tuning flag defines the initial size of metaspace If you don’t specify this flag, the Metaspace will dynamically re-size depending of the application demand at runtime.

Change enables other optimizations and features in the future

• Application class data sharing
• Young collection optimizations, G1 class unloading
• Metadata size reductions and internal JVM footprint projects

There is improved GC performace also.

http://docs.python.org/reference/compound_stmts.html

Compound statements consist of one or more ‘clauses.’ A clause consists of a header and a ‘suite.’ The clause headers of a particular compound statement are all at the same indentation level. Each clause header begins with a uniquely identifying keyword and ends with a colon. A suite is a group of statements controlled by a clause. A suite can be one or more semicolon-separated simple statements on the same line as the header, following the header’s colon, or it can be one or more indented statements on subsequent lines. Only the latter form of suite can contain nested compound statements; the following is illegal, mostly because it wouldn’t be clear to which if clause a following else clause would belong:

if test1: if test2: print x

Also note that the semicolon binds tighter than the colon in this context, so that in the following example, either all or none of the print statements are executed:

if x < y < z: print x; print y; print z 

Summarizing:

compound_stmt ::=  if_stmt
                   | while_stmt
                   | for_stmt
                   | try_stmt
                   | with_stmt
                   | funcdef
                   | classdef
                   | decorated
suite         ::=  stmt_list NEWLINE | NEWLINE INDENT statement+ DEDENT
statement     ::=  stmt_list NEWLINE | compound_stmt
stmt_list     ::=  simple_stmt (";" simple_stmt)* [";"]

With xampp I think you need to use the full path at the command line, something like this, perhaps:

C:\xampp\mysql\bin\mysql -u {username} -p {databasename} < file_name.sql

Assuming that you didn't set a precision initially, it's assumed to be the maximum (38). You're reducing the precision because you're changing it from 38 to 14.

The easiest way to handle this is to rename the column, copy the data over, then drop the original column:

alter table EVAPP_FEES rename column AMOUNT to AMOUNT_OLD;

alter table EVAPP_FEES add AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_OLD;

alter table EVAPP_FEES drop column AMOUNT_OLD;

If you really want to retain the column ordering, you can move the data twice instead:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

In order to view all the SQL and parameters in OpenJPA, put these two parameters in the persistence.xml:

<property name="openjpa.Log" value="DefaultLevel=WARN, Runtime=INFO, Tool=INFO, SQL=TRACE"/>
<property name="openjpa.ConnectionFactoryProperties" value="PrintParameters=true" />

Yet another method to solve: updating registry. In my case I could not alter GPO, and -UseBasicParsing breaks parts of the access to the website. Also I had a service user without log in permissions, so I could not log in as the user and run the GUI.
To fix,

1. log in as a normal user, run IE setup.
2. Then export this registry key: HKEY_USERS\S-1-5-21-....\SOFTWARE\Microsoft\Internet Explorer
3. In the .reg file that is saved, replace the user sid with the service account sid
4. Import the .reg file

In the file

None of these answers helped with Ubuntu. Finally I ran across a solution from John Papa (lite-server's author).

On Ubuntu 15.10 the Angular 2 Quick Start sprang to life after running this at the terminal:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Apparently it increases the number of available File Watches.

Answer Source: https://github.com/johnpapa/lite-server/issues/9

In CI v3, you can try:

function partial_uri($start = 0) {
    return join('/',array_slice(get_instance()->uri->segment_array(), $start));
}

This will drop the number of URL segments specified by the $start argument. If your URL is http://localhost/dropbox/derrek/shopredux/ahahaha/hihihi, then:

partial_uri(3);  # returns "ahahaha/hihihi"

This is how you do it:

1. Forget IE8/IE9, it is not worth the effort and does not pay the money back.
2. You need to use the right HTTP header,use Accept to 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' and also you need to put responseType to 'arraybuffer'(ArrayBuffer but set with lowercase).
3. HTML5 saveAs is used to save the actual data to your wanted format. Note it will still work without adding type in this case.

$http({
    url: 'your/webservice',
    method: 'POST',
    responseType: 'arraybuffer',
    data: json, //this is your json data string

Tip! Don't mix " and ', stick to always use ', in a professional environment you will have to pass js validation for example jshint, same goes for using === and not ==, and so on, but that is another topic :)

I would put the save excel in another service, so you have clean structure and the post is in a proper service of its own. I can make a JS fiddle for you, if you don't get my example working. Then I would also need some json data from you that you use for a full example.

Happy coding.. Eduardo

If you want to explore options of communicating between components and feel like it is getting harder and harder, then you might consider adopting a good design pattern: Flux.

It is simply a collection of rules that defines how you store and mutate application wide state, and use that state to render components.

There are many Flux implementations, and Facebook's official implementation is one of them. Although it is considered the one that contains most boilerplate code, but it is easier to understand since most of the things are explicit.

Some of Other alternatives are flummox fluxxor fluxible and redux.

it makes the assignment visible to subprocesses.

$ foo=bar
$ bash -c 'echo $foo'

$ export foo
$ bash -c 'echo $foo'
bar

I would not do that. I would keep the profileID as primary key of the table Profile

A foreign key is just a referential constraint between two tables

One could argue that a primary key is necessary as the target of any foreign keys which refer to it from other tables. A foreign key is a set of one or more columns in any table (not necessarily a candidate key, let alone the primary key, of that table) which may hold the value(s) found in the primary key column(s) of some other table. So we must have a primary key to match the foreign key. Or must we? The only purpose of the primary key in the primary key/foreign key pair is to provide an unambiguous join - to maintain referential integrity with respect to the "foreign" table which holds the referenced primary key. This insures that the value to which the foreign key refers will always be valid (or null, if allowed).

You have to explicitly define the constructor in B and explicitly call the constructor for the parent.

B(int x) : A(x) { }

or

B() : A(5) { }

To persist audit data regarding data modifications, you will need to implement a DML Trigger on each table that you are interested in. You will need to create an Audit table, and add code to your triggers to write to this table.

For more details on how to implement DML triggers, refer to this MDSN article http://msdn.microsoft.com/en-us/library/ms191524%28v=sql.105%29.aspx

In xCode 11, Swift 5 the \n works fine, try the below code:

textlabel.numberOfLines = 0
textlabel.text = "This is line one \n This is line two \n This is line three"

If you're looking for a solution for Redshift, this will work with the frame clause:

SELECT date, 
       last_value(columnName ignore nulls) 
                   over (order by date
                         rows between unbounded preceding and current row) as columnName 
 from tbl

java.lang.UnsupportedOperationException

Mongo shell command that worked for me:

db.getCollection(<collection_name>).aggregate([{"$match": {'<key>': '<value to match>'}}, {"$group": {'_id': {'<group_by_attribute>': "$group_by_attribute"}}}])

Copy xampp_start.exe from your XAMPP install directory to C:\Users\YOUR USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup.

Replace YOUR USERNAME with your username.

If using Spring Boot this works well. Even with Spring Reactive Mongo.
