The above answers require you to malloc a new stream object.

public <T>
boolean containsByLambda(Collection<? extends T> c, Predicate<? super T> p) {

    for (final T z : c) {
        if (p.test(z)) {
            return true;
        }
    }
    return false;
}

public boolean containsTabById(TabPane tabPane, String id) {
    return containsByLambda(tabPane.getTabs(), z -> z.getId().equals(id));
}
...
if (containsTabById(tabPane, idToCheck))) {
   ...
}

If you are designing your Javafx application using SceneBuilder then use -fx-text-fill(if not available as option then write it in style input box) as style and give the color you want,it will change the text color of your Textfield.

I came here for the same problem and solved it in this way.

This work for me:

let inputValue = (swal.getPopup().querySelector('#inputValue ')as HTMLInputElement).value

Python tells me where it lives when it gives me an error message :)

>>> import os
>>> os.environ['PYTHONPATH'].split(os.pathsep)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\martin\AppData\Local\Programs\Python\Python36-32\lib\os.py", line 669, in __getitem__

As stated in other answers, you can use WindowStyle="None" to remove the Title Bar altogether.

And, as stated in the comments to those other answers, this prevents the window from being draggable so it is hard to move it from its initial position.

However, you can overcome this by adding a single line of code to the Constructor in the Window's Code Behind file:

MouseDown += delegate { DragMove(); };

Or, if you prefer Lambda Syntax:

MouseDown += (sender, args) => DragMove();

This makes the entire Window draggable. Any interactive controls present in the Window, such as Buttons, will still work as normal and won't act as drag-handles for the Window.

1. Save and close all Internet Explorer windows and then, run Windows Task Manager to end the running processes in background.
2. Go to Control Panel.
3. Click Programs and choose the View installed updates instead.
4. Locate the following Windows Internet Explorer 11 or you can type "Internet Explorer" for a quick search.
5. Choose the Yes option from the following "Uninstall an update".
6. Please wait while Windows Internet Explorer 10 is being restored and reconfigured automatically.
7. Follow the Microsoft Windows wizard to restart your system.

Note: You can do it for as many earlier versions you want, i.e. IE9, IE8 and so on.

Call decode() on a bytes instance to get the text which it encodes.

str = bytes.decode()

Just to make this absolutely clear for all:

A .MDF file is “typically” a SQL Server data file however it is important to note that it does NOT have to be.

This is because .MDF is nothing more than a recommended/preferred notation but the extension itself does not actually dictate the file type.

To illustrate this, if someone wanted to create their primary data file with an extension of .gbn they could go ahead and do so without issue.

To qualify the preferred naming conventions:

• .mdf - Primary database data file.
• .ndf - Other database data files i.e. non Primary.
• .ldf - Log data file.

This should work

This answer may help if: 1) your site used to work with Windows authentication before upgrading to Visual Studio 2015 and 2) and your site is attempting to load /login.aspx (even though there is no such file on your site).

Add the following two lines to the appSettingssection of your site's Web.config.

<add key="autoFormsAuthentication" value="false" />
<add key="enableSimpleMembership" value="false"/>

I would like to comment on this, even tough Its old post. So, basically, I want to combine 2 answers, one from this post and one from another post that I read, don't know the author of it so please sorry for using your methods.

So, here are my classes for achieveving desired result:

    public class StartActivity extends Activity {
    public static final int REQUEST_CODE = 5912;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        PackageManager p = getPackageManager();
        ComponentName componentName = new ComponentName(this, StartActivity.class); // activity which is first time open in manifiest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
        p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
        startService(new Intent(this, StartService.class));
        startService(new Intent(this, SmsOutgoingService.class));
        try {
            // Initiate DevicePolicyManager.
            DevicePolicyManager mDPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
            ComponentName mAdminName = new ComponentName(this, DeviceAdminReciever.class);

            if (!mDPM.isAdminActive(mAdminName)) {
                Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
                intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
                intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "Click on Activate button to secure your application.");
                startActivityForResult(intent, REQUEST_CODE);
            } else {
                mDPM.lockNow();
                finish();
//                 Intent intent = new Intent(MainActivity.this,
//                 TrackDeviceService.class);
//                 startService(intent);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (REQUEST_CODE == requestCode) {
            startService(new Intent(StartActivity.this, TService.class));
            finish();
        }
        super.onActivityResult(requestCode, resultCode, data);
    }
}

And my TService class:

}

inside TService class you will find CallReceiever class that is going to handle everything you need from the call. You can add parameters as per your will, but, the main point is important.

From your MainActvitiy call Service that will start your Receiever. If you want to record media from receiever directly, you will get errors, so, you need to register Receiever from service. After that, you can call start recording and end recording wherever you like. Calling return super.onStartCommand(intent, flags, startId); will have that Service lasting for more than one call, so keep that in mind.

Finally, AndroidManifest.xml file:

So, this is it, its working perfectly with my Samsung Galaxy s6 Edge+, Ive tested it on Galaxy Note 4 and on Samsung J5, a big thank you to the authors of this post and the post about receieving phone calls.

It may be worth getting into the habit of using printf rather then echo on the command line.

In this example it doesn't give much benefit but it can be more useful with more complex output.

FOO="BAR * BAR"
printf %s "$FOO"

You have correctly used "CURLOPT_COOKIEJAR" (writing) but you also need to set "CURLOPT_COOKIEFILE" (reading)

curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE); 

Play with tcpdump or wireshark and see what commands are sent to the server itself

Try this

printf (printf "$username\r\n$password\r\nwhoami\r\nexit\r\n") | ncat $target 23

Some servers require a delay with the password as it does not hold lines on the stack

printf (printf "$username\r\n";sleep 1;printf "$password\r\nwhoami\r\nexit\r\n") | ncat $target 23**

Python variables are scoped to the innermost function, class, or module in which they're assigned. Control blocks like if and while blocks don't count, so a variable assigned inside an if is still scoped to a function, class, or module.

(Implicit functions defined by a generator expression or list/set/dict comprehension do count, as do lambda expressions. You can't stuff an assignment statement into any of those, but lambda parameters and for clause targets are implicit assignment.)

the third way is to base64 encode the image and place it in a data: url

example:

<img src="data:image/png;base64,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" width="32" height="32">

server.xml is created when you publish a project.Now If you add more dependency later then server.xml will not be able to catch it until and unless it is refreshed again. Sometimes you need to rebuild context/config file also. First you try to clean the work directory.If it doesn't work then delete server and Server folder,then reconfigure those two.

I'm assuming you've got a nice fat USB HD and a good connection to the net. You can use apt-mirror to essentially create your own debian mirror.

http://apt-mirror.sourceforge.net/

You can use JavaScripts Fetch API (available in your browser) to make network requests.

If using node, you will need to install the node-fetch package.

const url = "https://api.wit.ai/message?v=20140826&q=";

const options = {
  headers: {
    Authorization: "Bearer 6Q************"
  }
};

fetch(url, options)
  .then( res => res.json() )
  .then( data => console.log(data) );

When I'm working with csv files, I often use the pandas library. It makes things like this very easy. For example:

import pandas as pd

a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)

Some explanation follows. First, we read in the csv files:

>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a

2  three  0.285  1.283  0.924  956.0000         NaN

and we see there's an extra column of data (note that the first line of fileb.csv -- title,mar,apr,may,jun, -- has an extra comma at the end). We can get rid of that easily enough:

>>> b = b.dropna(axis=1)
>>> b
   title    mar    apr    may       jun
0   darn  0.631  1.321  0.951    1.7510

2  three  0.285  1.283  0.924  956.0000

Now we can merge a and b on the title column:

>>> merged = a.merge(b, on='title')
>>> merged
   title  stage    jan    feb    mar    apr    may       jun
0   darn  3.001  0.421  0.532  0.631  1.321  0.951    1.7510

2  three  1.115  1.146  2.921  0.285  1.283  0.924  956.0000

and finally write this out:

>>> merged.to_csv("output.csv", index=False)

producing:

title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751

If you use the NetBeans IDE (latest version at this time is 6.5.1), you can use it to create a basic GUI java application using File->New Project and choose the Java category then Java Desktop Application.

Once created, you will have a simple bare bones GUI app which contains an about box that can be opened using a menu selection. You should be able to adapt this to your needs and learn how to open a dialog from a button click.

You will be able to edit the dialog visually. Delete the items that are there and add some text areas. Play around with it and come back with more questions if you get stuck :)

If you have Perl 5.14 or greater, you can use the /r option with the substitution operator to perform non-destructive substitution:

print "bla: ", $myvar =~ s/a/b/r, "\n";

In earlier versions you can achieve the same using a do() block with a temporary lexical variable, e.g.:

print "bla: ", do { (my $tmp = $myvar) =~ s/a/b/; $tmp }, "\n";

I'd generally recommend you leave the formatting up to your front-end code and just return the data as-is from SQL. However, to do it in SQL, I'd recommend you create a user-defined function to format it. Something like this:

CREATE FUNCTION [dbo].[fnFormatPhoneNumber](@PhoneNo VARCHAR(20))
RETURNS VARCHAR(25)
AS
BEGIN
DECLARE @Formatted VARCHAR(25)

IF (LEN(@PhoneNo) <> 10)
    SET @Formatted = @PhoneNo
ELSE
    SET @Formatted = LEFT(@PhoneNo, 3) + '-' + SUBSTRING(@PhoneNo, 4, 3) + '-' + SUBSTRING(@PhoneNo, 7, 4)

RETURN @Formatted
END
GO

Which you can then use like this:

SELECT [dbo].[fnFormatPhoneNumber](PhoneNumber) AS PhoneNumber
FROM SomeTable

It has a safeguard in, in case the phone number stored isn't the expected number of digits long, is blank, null etc - it won't error.

EDIT: Just clocked on you want to update your existing data. The main bit that's relevant from my answer then is that you need to protect against "dodgy"/incomplete data (i.e. what if some existing values are only 5 characters long)

The easy method that will work even in corrupted setup environment is :

You typically only use an alias for a table name when you need to prefix a column with the table name due to duplicate column names in the joined tables and the table name is long or when the table is joined to itself. In your case you use an alias for VCustomer but only use it in the ON clause for uncertain reasons. You may want to review that aspect of your code.

I know it's a bit late but I had issues with a modal window not allowing some links on the menu bar to work, even when it has not been triggered. But I solved it by doing the following:

.modal{
display:none;
}

Simply by "unpacking" the list in the print function argument and using a newline (\n) as separator.

print(*lst, sep='\n')

lst = ['foo', 'bar', 'spam', 'egg']
print(*lst, sep='\n')

foo
bar
spam
egg

I had a similar problem, trying to add a background image with inline css. No need to specify the images folder due to the way asset sync works.

This worked for me:

background-image: url('/assets/image.jpg');

Create a list of lists:

with open("/path/to/file") as file:
    lines = []
    for line in file:
        # The rstrip method gets rid of the "\n" at the end of each line
        lines.append(line.rstrip().split(","))

yet another edit: As of version 5.2 pluck is not deprecated anymore, it just got new behaviour (same as lists previously - see side-note below):

edit: As of version 5.1 pluck is deprecated, so start using value instead:

DB::table('users')->where('username', $username)->value('groupName');    

// valid for L4 / L5.0 only
DB::table('users')->where('username', $username)->pluck('groupName');

this will return single value of groupName field of the first row found.

SIDE NOTE reg. @TomasButeler comment: As Laravel doesn't follow sensible versioning, there are sometimes cases like this. At the time of writing this answer we had pluck method to get SINGLE value from the query (Laravel 4.* & 5.0).

Then, with L5.1 pluck got deprecated and, instead, we got value method to replace it.

But to make it funny, pluck in fact was never gone. Instead it just got completely new behaviour and... deprecated lists method.. (L5.2) - that was caused by the inconsistency between Query Builder and Collection methods (in 5.1 pluck worked differently on the collection and query, that's the reason).

First of all, I wouldn't use a multi-dimensional array. Only ever seen bad things come of it.

Set up your variable like this:

IEnumerable<IEnumerable<string>> data = new[] {
    new[]{"...", "...", "..."},
    ... etc ...
};

Then you'd simply go:

var firsts = data.Select(x => x.FirstOrDefault()).Where(x => x != null); 

The Where makes sure it prunes any nulls if you have an empty list as an item inside.

Alternatively you can implement it as:

string[][] = new[] {
    new[]{"...","...","..."},
    new[]{"...","...","..."},
    ... etc ...
};

This could be used similarly to a [x,y] array but it's used like this: [x][y]

You'll want to modify the manifest that gets embedded in the program. This works on Visual Studio 2008 and higher: Project + Add New Item, select "Application Manifest File". Change the <requestedExecutionLevel> element to:

 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

The user gets the UAC prompt when they start the program. Use wisely; their patience can wear out quickly.

I use EditText.setFocusable(false) and set true again if I want to edit.

Connecting to any mysql database should be like this:

$mysql -h hostname -Pportnumber -u username -p (then enter)

Then it will ask for password. Note: Port number should be closer to -P or it will show error. Make sure you know what is your mysql port. Default is 3306 and is optional to specify the port in this case. If its anything else you need to mention port number with -P or else it will show error.

For example: $mysql -h 10.20.40.5 -P3306 -u root -p (then enter)

Password:My_Db_Password

Gubrish about product you using.

Note: If you are trying to connect a db at different location make sure you can ping to that server/computer.

$ping 10.20.40.5

It should return TTL with time you got back PONG. If it says destination unreachable then you cannot connect to remote mysql no matter what.

In such case contact your Network Administrator or Check your cable connection to your computer till the end of your target computer. Or check if you got LAN/WAN/MAN or internet/intranet/extranet working.

If you're only interested in international numbers and you'd like to be able to show the flag of the country that matches the country code in the input, I wrote a small library for that:

https://github.com/tfcporciuncula/phonemoji

Here's how it looks:

Besides being a bitwise complement operator, ~ can also help revert a boolean value, though it is not the conventional bool type here, rather you should use numpy.bool_.

This is explained in,

import numpy as np
assert ~np.True_ == np.False_

Reversing logical value can be useful sometimes, e.g., below ~ operator is used to cleanse your dataset and return you a column without NaN.

from numpy import NaN
import pandas as pd

matrix = pd.DataFrame([1,2,3,4,NaN], columns=['Number'], dtype='float64')
# Remove NaN in column 'Number'
matrix['Number'][~matrix['Number'].isnull()]

Here's a fairly compact one I created.

Search: \+?1?\s*\(?-*\.*(\d{3})\)?\.*-*\s*(\d{3})\.*-*\s*(\d{4})$

Replace: +1 \($1\) $2-$3

You'll want to use getUserMedia to access the camera.

This tutorial outlines the basics of accessing a device camera from the browser: https://medium.com/@aBenjamin765/make-a-camera-web-app-tutorial-part-1-ec284af8dddf

Remove protected $dates = ['license_expire']

and then change your LicenseExpire accessor to:

public function getLicenseExpireAttribute($date)
{
    return Carbon::parse($date);
}

This way it will return a Carbon instance no matter what. So for your form you would just have $employee->license_expire->format('Y-m-d') (or whatever format is required) and diffForHumans() should work on your home page as well.

Hope this helps!

If the fallback keys are not too many you can do something like this

value = my_dict.get('first_key') or my_dict.get('second_key')

$('#mainn').text(function (_,txt) {
    return txt.slice(0, -1);
});

To access the elements in the array, use array notation: $product['prodname']

$product->prodname is object notation, which can only be used to access object attributes and methods.

Mark's iterative approach would be the usual way, I think.

Here's an alternative with string-splitting, which can often be useful for finding-related processes:

def findnth(haystack, needle, n):
    parts= haystack.split(needle, n+1)
    if len(parts)<=n+1:
        return -1
    return len(haystack)-len(parts[-1])-len(needle)

And here's a quick (and somewhat dirty, in that you have to choose some chaff that can't match the needle) one-liner:

'foo bar bar bar'.replace('bar', 'XXX', 1).find('bar')

Yesterday Date can be calculated as:-

let now = new Date();
    var defaultDate = now - 1000 * 60 * 60 * 24 * 1;
    defaultDate = new Date(defaultDate);

Using map:

#include <iostream>
#include <map>
#include <string>

enum Errors {ErrorA=0, ErrorB, ErrorC};

std::ostream& operator<<(std::ostream& out, const Errors value){
    static std::map<Errors, std::string> strings;
    if (strings.size() == 0){
#define INSERT_ELEMENT(p) strings[p] = #p
        INSERT_ELEMENT(ErrorA);     
        INSERT_ELEMENT(ErrorB);     
        INSERT_ELEMENT(ErrorC);             
#undef INSERT_ELEMENT
    }   

    return out << strings[value];
}

int main(int argc, char** argv){
    std::cout << ErrorA << std::endl << ErrorB << std::endl << ErrorC << std::endl;
    return 0;   
}

Using array of structures with linear search:

#include <iostream>
#include <string>

enum Errors {ErrorA=0, ErrorB, ErrorC};

std::ostream& operator<<(std::ostream& out, const Errors value){
#define MAPENTRY(p) {p, #p}
    const struct MapEntry{
        Errors value;
        const char* str;
    } entries[] = {
        MAPENTRY(ErrorA),
        MAPENTRY(ErrorB),
        MAPENTRY(ErrorC),
        {ErrorA, 0}//doesn't matter what is used instead of ErrorA here...
    };
#undef MAPENTRY
    const char* s = 0;
    for (const MapEntry* i = entries; i->str; i++){
        if (i->value == value){
            s = i->str;
            break;
        }
    }

    return out << s;
}

int main(int argc, char** argv){
    std::cout << ErrorA << std::endl << ErrorB << std::endl << ErrorC << std::endl;
    return 0;   
}

Using switch/case:

#include <iostream>
#include <string>

enum Errors {ErrorA=0, ErrorB, ErrorC};

std::ostream& operator<<(std::ostream& out, const Errors value){
    const char* s = 0;
#define PROCESS_VAL(p) case(p): s = #p; break;
    switch(value){
        PROCESS_VAL(ErrorA);     
        PROCESS_VAL(ErrorB);     
        PROCESS_VAL(ErrorC);
    }
#undef PROCESS_VAL

    return out << s;
}

int main(int argc, char** argv){
    std::cout << ErrorA << std::endl << ErrorB << std::endl << ErrorC << std::endl;
    return 0;   
}

Use INDIRECT()

=SUM(INDIRECT(<start cell here> & ":" & <end cell here>))

Yes, it is mainly to anchor your keywords, in particular the location of your page, so whenever URL loads the page with particular anchor name, then it will be pointed to that particular location.

For example, www.something.com/some_page/#computer if it is very lengthy page and you want to show exactly computer then you can anchor.

<p> adfadsf </p>
<p> adfadsf </p>
<p> adfadsf </p>
<a name="computer"></a><p> Computer topics </p>
<p> adfadsf </p>

Now the page will scroll and bring computer-related topics to the top.

You want to init an array of ints in your constructor? Point it to a static array.

class C 
{
public:
    int *cArray;

};

C::C {
    static int c_init[]{1,2,3};
    cArray = c_init;
}

just close the VS Code to solve the issue for me

Yes you can. The abstract class used in java signifies that you can't create an object of the class. And an abstract method the subclasses have to provide an implementation for that method.

So you can easily define an abstract class without any abstract method.

As for Example :

public abstract class AbstractClass{

    public String nonAbstractMethodOne(String param1,String param2){
        String param = param1 + param2;
        return param;
    }

    public static void nonAbstractMethodTwo(String param){
        System.out.println("Value of param is "+param);
    }
}

This is fine.

I tested what @Samy Dindane suggested in the comment on the OP.

I believe it works, try

git fetch <remote_name> <remote_branch>:<local_branch>
git checkout <local_branch>

Here's an example for a fictitious remote repository named foo with a branch named bar where I create a local branch bar tracking the remote:

git fetch foo bar:bar
git checkout bar

That is so basic that I am wondering what book you are using to study? Try

data[1, "V1"]  # row first, quoted column name second, and case does matter

Further note: Terminology in discussing R can be crucial and sometimes tricky. Using the term "table" to refer to that structure leaves open the possibility that it was either a 'table'-classed, or a 'matrix'-classed, or a 'data.frame'-classed object. The answer above would succeed with any of them, while @BenBolker's suggestion below would only succeed with a 'data.frame'-classed object.

I am unrepentant in my phrasing despite the recent downvote. There is a ton of free introductory material for beginners in R: https://cran.r-project.org/other-docs.html

I was searching why % doesn't seem to work. So, I tested out using 100vh instead of just setting it at 100% it seems that 100vh works really well across almost all browsers/devices.

example: you want to only display the top div to the user before it scrolls, like a hero banner module. But, at the top of the page is a navbar which is 68px in height. The following doesn't work for me at all doing just %

height: calc(100% - 68px); 

There's was no change. The page just stayed the same. However, when swapping this to "vh" instead it works great! The div block you assign it too will stay on the viewer's device hight only. Until they decide to scroll down the page.

height: calc(100vh - 68px); 

Change the +/- to include how big your header is on the top. If your navbar is say 120px in height then change 68px to 120px.

Hope this helps anyone who cannot get this working with using normal height: calc();

HTMLUnit can be used to do web scraping, it supports invoking pages, filling & submitting forms. I have used this in my project. It is good java library for web scraping. read here for more

This String extension removes all whitespace from a string, not just trailing whitespace ...

 extension String {
    func replace(string:String, replacement:String) -> String {
        return self.replacingOccurrences(of: string, with: replacement, options: NSString.CompareOptions.literal, range: nil)
    }

    func removeWhitespace() -> String {
        return self.replace(string: " ", replacement: "")
    }
  }

Example:

let string = "The quick brown dog jumps over the foxy lady."
let result = string.removeWhitespace() // Thequickbrowndogjumpsoverthefoxylady.

Sometimes you want to have your GridView as simple as:

  <asp:GridView ID="grid" runat="server" />

You don't want to specify any BoundField, you just want to bind your grid to DataReader. The following code helped me to format DateTime in this situation.

protected void Page_Load(object sender, EventArgs e)
{
  grid.RowDataBound += grid_RowDataBound;
  // Your DB access code here...
  // grid.DataSource = cmd.ExecuteReader(CommandBehavior.CloseConnection);
  // grid.DataBind();
}

void grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType != DataControlRowType.DataRow)
    return;
  var dt = (e.Row.DataItem as DbDataRecord).GetDateTime(4);
  e.Row.Cells[4].Text = dt.ToString("dd.MM.yyyy");
}

ZXing is an open source project that can detect and parse a number of different barcodes. It can also generate QR-codes. (Only QR-codes, though).

There are a number of variants for different languages: ActionScript, Android (java), C++, C#, IPhone (Obj C), Java ME, Java SE, JRuby, JSP. Support for generating QR-codes comes with some of those: ActionScript, Android, C# and the Java variants.

Sounds like you are using Microsoft Visual C++. If that is the case, then the most possibility is that you don't compile your two.cpp with one.cpp (one.cpp is the implementation for one.h).

If you are from command line (cmd.exe), then try this first: cl -o two.exe one.cpp two.cpp

If you are from IDE, right click on the project name from Solution Explore. Then choose Add, Existing Item.... Add one.cpp into your project.

I was also stuck in similar kind of situation, setLevel() method was not coming, when I was trying to call it with the instance of HttpLoggingInterceptor, like this:

HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

Here is how I resolved it, to generate log for Retrofit2,

I suppose you have added the dependecy,

implementation "com.squareup.okhttp3:logging-interceptor:4.7.2"

For the latest version you can check out, this link:

https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor )

Here they have also explained about how to add.

I created a class with name AddLoggingInterceptor, here is my code,

public class AddLoggingInterceptor {

    public static OkHttpClient setLogging(){
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .addInterceptor(loggingInterceptor)
                .build();

        return okHttpClient;
    }
}

Then, where we are instantiating our Retrofit,

 public static Retrofit getRetrofitInstance() {
    if (retrofit == null) {
        retrofit = new retrofit2.Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .client(AddLoggingInterceptor.setLogging()) // here the method is called inside client() method, with the name of class, since it is a static method.
                .build();
    }
    return retrofit;
}

Now you can see log generated in your Android Studio, you may need to search, okHttp for filtering process. It worked for me. If any issues you can text me here.

You need to loop over loadDT.Columns, like this:

foreach (DataColumn column in loadDT.Columns)
{
    Console.Write("Item: ");
    Console.Write(column.ColumnName);
    Console.Write(" ");
    Console.WriteLine(row[column]);
}

It is General sibling combinator and is explained in @Salaman's answer very well.

What I did miss is Adjacent sibling combinator which is + and is closely related to ~.

example would be

.a + .b {
  background-color: #ff0000;
}

<ul>
  <li class="a">1st</li>
  <li class="b">2nd</li>
  <li>3rd</li>
  <li class="b">4th</li>
  <li class="a">5th</li>
</ul>

• Matches elements that are .b
• Are adjacent to .a
• After .a in HTML

In example above it will mark 2nd li but not 4th.

   .a + .b {_x000D_
     background-color: #ff0000;_x000D_
   }

<ul>_x000D_
  <li class="a">1st</li>_x000D_
  <li class="b">2nd</li>_x000D_
  <li>3rd</li>_x000D_
  <li class="b">4th</li>_x000D_
  <li class="a">5th</li>_x000D_
</ul>

Javascript

(function () {
var textFile = null,
  makeTextFile = function (text) {
    var data = new Blob([text], {type: 'text/plain'});
    if (textFile !== null) {
      window.URL.revokeObjectURL(textFile);
    }
    textFile = window.URL.createObjectURL(data);
    return textFile;
  };

  var create = document.getElementById('create'),
    textbox = document.getElementById('textbox');
  create.addEventListener('click', function () {
    var link = document.getElementById('downloadlink');
    link.href = makeTextFile(textbox.value);
    link.style.display = 'block';
  }, false);
})();

I am fairly new to Javascript. But this is what I understood: JSON.parse() returns SyntaxError exceptions when invalid JSON is provided as its first parameter. So. It would be better to catch that exception as such like as follows:

try {
    let sData = `
        {
            "id": "1",
            "name": "UbuntuGod",
        }
    `;
    console.log(JSON.parse(sData));
} catch (objError) {
    if (objError instanceof SyntaxError) {
        console.error(objError.name);
    } else {
        console.error(objError.message);
    }
}

The reason why I made the words "first parameter" bold is that JSON.parse() takes a reviver function as its second parameter.

I know this is a late response, but a neat way of doing this is to ping the broadcast address which populates your local arp cache.

This can then be shown by running arp -a which will list all the addresses in you local arp table.

ping 192.168.1.255
arp -a

Hopefully this is a nice neat option that people can use.

Tested in Java 1.8. I hope this will help some one.

You can Change Backcolor row by row using your condition.and this function call after applying Datasource of DatagridView.

Here Is the function for that. Simply copy that and put it after Databind

private void ChangeRowColor()
{
    for (int i = 0; i < gvItem.Rows.Count; i++)
    {
        if (BindList[i].MainID == 0 && !BindList[i].SchemeID.HasValue)
            gvItem.Rows[i].DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#C9CADD");
        else if (BindList[i].MainID > 0 && !BindList[i].SchemeID.HasValue)
            gvItem.Rows[i].DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#DDC9C9");
        else if (BindList[i].MainID > 0)
            gvItem.Rows[i].DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#D5E8D7");
        else
            gvItem.Rows[i].DefaultCellStyle.BackColor = Color.White;
    }
}

If the code of the previous posts doesn't work, give this a try:

$("a.ui-dialog-titlebar-close")[0].click();

Using the method, String.valueOf() you do not have to worry about the data(whether it is int,long,char,char[],boolean,Object), you can just call :

• static String valueOf()

using the only syntax String.valueOf() can whatever you pass as a parameter is converted to String and returned..

Otherwise, if you use Integer.toString(),Float.toString() etc.(i.e. SomeType.toString()) then you will have to check the datatype of parameter that you want to convert into string. So, its better to use String.valueOf() for such convertions.

If you are having an array of object class that contains different values like Integer,Char,Float etc. then by using String.valueOf() method you can convert the elements of such array into String form easily. On contrary, if you want to use SomeType.toString() then at first you will need to know about there their datatype classes(maybe by using "instanceOf" operator) and then only you can proceed for a typecast.

String.valueOf() method when called matches the parameter that is passed(whether its Integer,Char,Float etc.) and by using method overloading calls that "valueOf()" method whose parameter gets matched, and then inside that method their is a direct call to corresponding "toString()" method..

So, we can see how the overhead of checking datatype and then calling corresponding "toString()" method is removed.Only we need is to call String.valueOf() method, not caring about what we want to convert to String.

Conclusion: String.valueOf() method has its importance just at cost of one more call.

var blob = new Blob([arrayBuffer])

var reader = new FileReader();
reader.onload = function(event){
   var base64 =   event.target.result
};

reader.readAsDataURL(blob);

You need antMatcher for multiple HttpSecurity, see Spring Security Reference:

5.7 Multiple HttpSecurity

We can configure multiple HttpSecurity instances just as we can have multiple <http> blocks. The key is to extend the WebSecurityConfigurationAdapter multiple times. For example, the following is an example of having a different configuration for URL’s that start with /api/.

@EnableWebSecurity
public class MultiHttpSecurityConfig {
  @Autowired
  public void configureGlobal(AuthenticationManagerBuilder auth) { 1
      auth
          .inMemoryAuthentication()
              .withUser("user").password("password").roles("USER").and()
              .withUser("admin").password("password").roles("USER", "ADMIN");
  }

  @Configuration
  @Order(1)                                                        2
  public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
      protected void configure(HttpSecurity http) throws Exception {
          http
              .antMatcher("/api/**")                               3
              .authorizeRequests()
                  .anyRequest().hasRole("ADMIN")
                  .and()
              .httpBasic();
      }
  }    

  @Configuration                                                   4
  public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

      @Override
      protected void configure(HttpSecurity http) throws Exception {
          http
              .authorizeRequests()
                  .anyRequest().authenticated()
                  .and()
              .formLogin();
      }
  }
}

1 Configure Authentication as normal

2 Create an instance of WebSecurityConfigurerAdapter that contains @Order to specify which WebSecurityConfigurerAdapter should be considered first.

3 The http.antMatcher states that this HttpSecurity will only be applicable to URLs that start with /api/

4 Create another instance of WebSecurityConfigurerAdapter. If the URL does not start with /api/ this configuration will be used. This configuration is considered after ApiWebSecurityConfigurationAdapter since it has an @Order value after 1 (no @Order defaults to last).

In your case you need no antMatcher, because you have only one configuration. Your modified code:

http
    .authorizeRequests()
        .antMatchers("/high_level_url_A/sub_level_1").hasRole('USER')
        .antMatchers("/high_level_url_A/sub_level_2").hasRole('USER2')
        .somethingElse() // for /high_level_url_A/**
        .antMatchers("/high_level_url_A/**").authenticated()
        .antMatchers("/high_level_url_B/sub_level_1").permitAll()
        .antMatchers("/high_level_url_B/sub_level_2").hasRole('USER3')
        .somethingElse() // for /high_level_url_B/**
        .antMatchers("/high_level_url_B/**").authenticated()
        .anyRequest().permitAll()

Here's the basic approach,

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

Date beginDate = dateFormat.parse("2013-11-29");
Date endDate = dateFormat.parse("2013-12-4");

Calendar beginCalendar = Calendar.getInstance();
beginCalendar.setTime(beginDate);

Calendar endCalendar = Calendar.getInstance();
endCalendar.setTime(endDate);

There is simple way to implement it. We can use Calendar.add method with loop. The minus days between beginDate and endDate, and the implemented code as below,

int minusDays = 0;
while (true) {
  minusDays++;

  // Day increasing by 1
  beginCalendar.add(Calendar.DAY_OF_MONTH, 1);

  if (dateFormat.format(beginCalendar.getTime()).
            equals(dateFormat.format(endCalendar).getTime())) {
    break;
  }
}
System.out.println("The subtraction between two days is " + (minusDays + 1));**

Use the Apache Commons CLI library commandline.getArgs() to get arg1, arg2, arg3, and arg4. Here is some code:

    import org.apache.commons.cli.CommandLine;
    import org.apache.commons.cli.Option;
    import org.apache.commons.cli.Options;
    import org.apache.commons.cli.Option.Builder;
    import org.apache.commons.cli.CommandLineParser;
    import org.apache.commons.cli.DefaultParser;
    import org.apache.commons.cli.ParseException;

    public static void main(String[] parameters)
    {
        CommandLine commandLine;
        Option option_A = Option.builder("A")
            .required(true)
            .desc("The A option")
            .longOpt("opt3")
            .build();
        Option option_r = Option.builder("r")
            .required(true)
            .desc("The r option")
            .longOpt("opt1")
            .build();
        Option option_S = Option.builder("S")
            .required(true)
            .desc("The S option")
            .longOpt("opt2")
            .build();
        Option option_test = Option.builder()
            .required(true)
            .desc("The test option")
            .longOpt("test")
            .build();
        Options options = new Options();
        CommandLineParser parser = new DefaultParser();

        String[] testArgs =
        { "-r", "opt1", "-S", "opt2", "arg1", "arg2",
          "arg3", "arg4", "--test", "-A", "opt3", };

        options.addOption(option_A);
        options.addOption(option_r);
        options.addOption(option_S);
        options.addOption(option_test);

        try
        {
            commandLine = parser.parse(options, testArgs);

            if (commandLine.hasOption("A"))
            {
                System.out.print("Option A is present.  The value is: ");
                System.out.println(commandLine.getOptionValue("A"));
            }

            if (commandLine.hasOption("r"))
            {
                System.out.print("Option r is present.  The value is: ");
                System.out.println(commandLine.getOptionValue("r"));
            }

            if (commandLine.hasOption("S"))
            {
                System.out.print("Option S is present.  The value is: ");
                System.out.println(commandLine.getOptionValue("S"));
            }

            if (commandLine.hasOption("test"))
            {
                System.out.println("Option test is present.  This is a flag option.");
            }

            {
                String[] remainder = commandLine.getArgs();
                System.out.print("Remaining arguments: ");
                for (String argument : remainder)
                {
                    System.out.print(argument);
                    System.out.print(" ");
                }

                System.out.println();
            }

        }
        catch (ParseException exception)
        {

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

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

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

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

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

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

What you're looking for is PATH.

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

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

#!/usr/bin/env python

And give execution privileges to it:

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

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

Try:

name = "^aH^ai"
name = name:gsub("%^a", "")

For those looking for an in-transaction solution, the following seems to work.

Instead of an ENUM, a DOMAIN shall be used on type TEXT with a constraint checking that the value is within the specified list of allowed values (as suggested by some comments). The only problem is that no constraint can be added (and thus neither modified) to a domain if it is used by any composite type (the docs merely says this "should eventually be improved"). Such a restriction may be worked around, however, using a constraint calling a function, as follows.

START TRANSACTION;

CREATE FUNCTION test_is_allowed_label(lbl TEXT) RETURNS BOOL AS $function$
    SELECT lbl IN ('one', 'two', 'three');
$function$ LANGUAGE SQL IMMUTABLE;

CREATE DOMAIN test_domain AS TEXT CONSTRAINT val_check CHECK (test_is_allowed_label(value));

CREATE TYPE test_composite AS (num INT, word test_domain);

CREATE TABLE test_table (val test_composite);
INSERT INTO test_table (val) VALUES ((1, 'one')::test_composite), ((3, 'three')::test_composite);
-- INSERT INTO test_table (val) VALUES ((4, 'four')::test_composite); -- restricted by the CHECK constraint

CREATE VIEW test_view AS SELECT * FROM test_table; -- just to show that the views using the type work as expected

CREATE OR REPLACE FUNCTION test_is_allowed_label(lbl TEXT) RETURNS BOOL AS $function$
    SELECT lbl IN ('one', 'two', 'three', 'four');
$function$ LANGUAGE SQL IMMUTABLE;

INSERT INTO test_table (val) VALUES ((4, 'four')::test_composite); -- allowed by the new effective definition of the constraint

SELECT * FROM test_view;

CREATE OR REPLACE FUNCTION test_is_allowed_label(lbl TEXT) RETURNS BOOL AS $function$
    SELECT lbl IN ('one', 'two', 'three');
$function$ LANGUAGE SQL IMMUTABLE;

-- INSERT INTO test_table (val) VALUES ((4, 'four')::test_composite); -- restricted by the CHECK constraint, again

SELECT * FROM test_view; -- note the view lists the restricted value 'four' as no checks are made on existing data

DROP VIEW test_view;
DROP TABLE test_table;
DROP TYPE test_composite;
DROP DOMAIN test_domain;
DROP FUNCTION test_is_allowed_label(TEXT);

COMMIT;

Previously, I used a solution similar to the accepted answer, but it is far from being good once views or functions or composite types (and especially views using other views using the modified ENUMs...) are considered. The solution proposed in this answer seems to work under any conditions.

The only disadvantage is that no checks are performed on existing data when some allowed values are removed (which might be acceptable, especially for this question). (A call to ALTER DOMAIN test_domain VALIDATE CONSTRAINT val_check ends up with the same error as adding a new constraint to the domain used by a composite type, unfortunately.)

Note that a slight modification such as CHECK (value = ANY(get_allowed_values())), where get_allowed_values() function returned the list of allowed values, would not work - which is quite strange, so I hope the solution proposed above works reliably (it does for me, so far...). (it works, actually - it was my error)

Although answer is provided I found simpler solution:

Date:

01/20/2017

By doing replace

CurrentDate = replace(date, "/", "-")

It will output:

01-20-2017

The shortest possible way to test if the value contained in a variable $v can be used as a number is:

number($v) = number($v)

You only need to substitute the $v above with the expression whose value you want to test.

Explanation:

number($v) = number($v) is obviously true, if $v is a number, or a string that represents a number.

It is true also for a boolean value, because a number(true()) is 1 and number(false) is 0.

Whenever $v cannot be used as a number, then number($v) is NaN

and NaN is not equal to any other value, even to itself.

Thus, the above expression is true only for $v whose value can be used as a number, and false otherwise.

Historically, the first extensions used for C++ were .c and .h, exactly like for C. This caused practical problems, especially the .c which didn't allow build systems to easily differentiate C++ and C files.

Unix, on which C++ has been developed, has case sensitive file systems. So some used .C for C++ files. Other used .c++, .cc and .cxx. .C and .c++ have the problem that they aren't available on other file systems and their use quickly dropped. DOS and Windows C++ compilers tended to use .cpp, and some of them make the choice difficult, if not impossible, to configure. Portability consideration made that choice the most common, even outside MS-Windows.

Headers have used the corresponding .H, .h++, .hh, .hxx and .hpp. But unlike the main files, .h remains to this day a popular choice for C++ even with the disadvantage that it doesn't allow to know if the header can be included in C context or not. Standard headers now have no extension at all.

Additionally, some are using .ii, .ixx, .ipp, .inl for headers providing inline definitions and .txx, .tpp and .tpl for template definitions. Those are either included in the headers providing the definition, or manually in the contexts where they are needed.

Compilers and tools usually don't care about what extensions are used, but using an extension that they associate with C++ prevents the need to track out how to configure them so they correctly recognize the language used.

2017 edit: the experimental module support of Visual Studio recognize .ixx as a default extension for module interfaces, clang++ is recognizing .c++m, .cppm and .cxxm for the same purpose.

Sorry but that's just much too much overhead (above), short and quick, if you have the MapFragment, you also have to map, just do the following:

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            googleMap.setMyLocationEnabled(true)
} else {
    // Show rationale and request permission.
}

Code is in Kotlin, hope you don't mind.

have fun

Btw I think this one is a duplicate of: Show Current Location inside Google Map Fragment

On PostgreSQL you can use:

SELECT * FROM table_name WHERE (boolean_column IS NULL OR NOT boolean_column)

The problem that you are facing is : TypeError : str returned non-string (type NoneType)

Here you have to understand the str function's working: the str fucntion,although is mostly used to print values but actually is designed to return a string,not to print one. In your class str function is calling the print directly while it is returning nothing ,that explains your error output.Since our formatted string is built, and since our function returns nothing, the None value is used. This was the explaination for your error

You can solve this problem by using the return in str function like: *simply returnig the string value instead of printing it

 class Summary(models.Model):
   book = models.ForeignKey(Book,on_delete = models.CASCADE)
   summary = models.TextField(max_length=600)

    def __str__(self):
        return self.summary

but if the value you are returning in not of string type then you can do like this to return string value from your str function

*typeconverting the value to string that your str function returns

class Summary(models.Model):
   book = models.ForeignKey(Book,on_delete = models.CASCADE)
   summary = models.TextField(max_length=600)

   def __str__(self):
       return str(self.summary)
            `

Well, first I will tell the errors in two code snippets.

First code snippet

public class Program
{
    public constructor() // Error - Return type for the method is missing
    {
        function();
    }        
    private void function()
    {
        //do stuff
    }   

    public static void main(String[] args)
    {
        constructor a = new constructor(); // Error - constructor cannot be resolved to a type
    }
}

As you can see the code above, constructor name is not same as class name. In the main() method you are creating a object from a method which has no return type.

Second code snippet

public class Program
{
    public static void main(String[] args)
    {
        function(); // Error - Cannot make a static reference to the non-static method function() from the type Program
    }

    private void function()
    {
        //do stuff
    } 
}

Now in this code snippet you're trying to create a static reference to the non-static method function() from the type Program, which is not possible.

So the possible solution is this,

First code snippet

public class Program
{
    public Program()
    {
        function();
    }        
    private void function()
    {
        //do stuff
    }   

    public static void main(String[] args)
    {
        Program a = new Program();
        a.function();
    }
}

Second code snippet

public class Program
{
    public static void main(String[] args)
    {
        Program a = new Program();
        a.function();
    }

    private void function()
    {
        //do stuff
    } 
}

Finally the difference between the code snippets is that, in first code snippet class name is not same as the class name

While in the second code snippet there is no constructor defined.

Meanwhile to understand the purpose of constructor refer resources below,

This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n and the output of np.add.reduce() are both scalars, this implies that the problem lies with xm and ym, the two of which are simply your x and y inputs minus their respective means.

Based on this, my guess is that your x and y inputs have different shapes from one another, making them incompatible for element-wise multiplication.

** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

From the documentation (help copy-item -full):

    Allows cmdlet to override restrictions such as renaming existing files as long as security is not compromised.

    Required?                    false

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

Your css will only work in IE browser. And the css suggessted by hayk.mart will olny work in webkit browsers. And by using different css hacks you can't style your browsers scroll bars with a same result.

So, it is better to use a jQuery/Javascript plugin to achieve a cross browser solution with a same result.

Solution:

By Using jScrollPane a jQuery plugin, you can achieve a cross browser solution

See This Demo

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

Short solution for preventing user from using context menu, copy and cut in jQuery:

jQuery(document).bind("cut copy contextmenu",function(e){
    e.preventDefault();
});

Also disabling text selection in CSS might come handy:

.noselect {  
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
     user-select: none;
}

We open a terminal and look for the location of java:

manuel@zonademanel:~ ? whereis java

java: /usr/bin/java /etc/java /usr/bin/X11/java /usr/share/java /usr/share/man/man1/java.1.gz

What we are looking for is /usr/bin/java continue on the command line to find the absolute path , as this is only a symbolic link.

manuel@zonademanel:~ ? ls -lah /usr/bin/java

lrwxrwxrwx 1 root root 22 may 19 2015 /usr/bin/java -> /etc/alternatives/java

manuel@zonademanel:~ ? ls -lah /etc/alternatives/java

lrwxrwxrwx 1 root root 39 dic 7 11:52 /etc/alternatives/java -> /usr/lib/jvm/java-8-oracle/jre/bin/java

I modified my /etc/environment file with the following values

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/java-8-oracle/jre/bin" JAVA_HOME="/usr/lib/jvm/java-8-oracle/jre"

If I do not want to relogin I can reload the changes with:

source /etc/environment 

??And run mvn -version correctly

I sort of agree with leander on this one.

call:

new calc_stanica().execute(stringList.toArray(new String[stringList.size()]));

task:

public class calc_stanica extends AsyncTask<String, Void, ArrayList<String>> {
        @Override
        protected ArrayList<String> doInBackground(String... args) {
           ...
        }

        @Override
        protected void onPostExecute(ArrayList<String> result) {
           ... //do something with the result list here
        }
}

Or you could just make the result list a class parameter and replace the ArrayList with a boolean (success/failure);

public class calc_stanica extends AsyncTask<String, Void, Boolean> {
        private List<String> resultList;

        @Override
        protected boolean doInBackground(String... args) {
           ...
        }

        @Override
        protected void onPostExecute(boolean success) {
           ... //if successfull, do something with the result list here
        }
}

If using inline-blocks is an option I would recommend this approach:

.container { 
    /* fixed position a zero-height full width container */
    position: fixed;
    top: 0; /* or whatever position is desired */
    left: 0;
    right: 0;
    height: 0;
    /* center all inline content */
    text-align: center;
}

.container > div {
    /* make the block inline */
    display: inline-block;
    /* reset container's center alignment */
    text-align: left;
} 

I wrote a short post on this here: http://salomvary.github.com/position-fixed-horizontally-centered.html

just fetch specific node data and its working perfect for me

mFirebaseInstance.getReference("yourNodeName").getRef().addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {


        for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
            Log.e(TAG, "======="+postSnapshot.child("email").getValue());
            Log.e(TAG, "======="+postSnapshot.child("name").getValue());
        }
    }

    @Override
    public void onCancelled(DatabaseError error) {
        // Failed to read value
        Log.e(TAG, "Failed to read app title value.", error.toException());
    }
});

If you use Windows 10 and has Windows Subsystem for Linux (WSL), it can be easily done by typing "file " from the shell.

For example:

$ file code.cpp

code.cpp: C source, UTF-8 Unicode (with BOM) text, with CRLF line terminators

Excellent answer simple and accurate.

I would add a code sample.

    class BreakContinue {

        public static void main( String [] args ) {

               for( int i = 0 ; i < 10 ; i++ ) {

                     if( i % 2 == 0) { // if pair, will jump
                         continue; // don't go to "System.out.print" below.
                     }

                     System.out.println("The number is " + i );

                     if( i == 7 ) {
                         break; // will end the execution, 8,9 wont be processed
                      }

               }
        }

    }

import array
integerValue = array.array("I", 'y\xcc\xa6\xbb')[0]

Warning: the above is strongly platform-specific. Both the "I" specifier and the endianness of the string->int conversion are dependent on your particular Python implementation. But if you want to convert many integers/strings at once, then the array module does it quickly.

This is a late contribution, but there is a valid case for casting json_decode with (array).
Consider the following:

$jsondata = '';
$arr = json_decode($jsondata, true);
foreach ($arr as $k=>$v){
    echo $v; // etc.
}

If $jsondata is ever returned as an empty string (as in my experience it often is), json_decode will return NULL, resulting in the error Warning: Invalid argument supplied for foreach() on line 3. You could add a line of if/then code or a ternary operator, but IMO it's cleaner to simply change line 2 to ...

$arr = (array) json_decode($jsondata,true);

... unless you are json_decodeing millions of large arrays at once, in which case as @TCB13 points out, performance could be negatively effected.

I personally made this python code to change the color of a whole image opened or created with openCV . I am sorry if it's not good enough , I am beginner .

def OpenCvImgColorChanger(img,blue = 0,green = 0,red = 0):
line = 1
ImgColumn = int(img.shape[0])-2
ImgRaw  = int(img.shape[1])-2



for j in range(ImgColumn):

    for i in range(ImgRaw):

        if i == ImgRaw-1:
            line +=1

        img[line][i][2] = int(red)
        img[line][i][1] = int(green)
        img[line][i][0] = int(blue)

This is best it will do the Job done. It will re-size your Map. No need to inspect element anymore to re-size your Map. What it does it will automatically trigger re-size event .

    google.maps.event.addListener(map, "idle", function()
        {
            google.maps.event.trigger(map, 'resize');
        });

        map_array[Next].setZoom( map.getZoom() - 1 );
    map_array[Next].setZoom( map.getZoom() + 1 );

apt-get install python2.7 will work on debian-like linuxes. The python website describes a whole bunch of other ways to get Python.

<button onclick="location.href='http://www.example.com'" type="button">_x000D_

Note that the type="button" attribute is important, since its missing value default is the Submit Button state.

This PHP at the top of the responding script seems to work. (With Firefox 3.6.11. I have not yet done a lot of testing.)

header('Access-Control-Allow-Methods: POST, GET, OPTIONS');
header('Access-Control-Max-Age: 1000');
if(array_key_exists('HTTP_ACCESS_CONTROL_REQUEST_HEADERS', $_SERVER)) {
    header('Access-Control-Allow-Headers: '
           . $_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']);
} else {
    header('Access-Control-Allow-Headers: *');
}

if("OPTIONS" == $_SERVER['REQUEST_METHOD']) {
    exit(0);
}

Best option I found was http://html2canvas.hertzen.com/
http://jsfiddle.net/nurbsurf/1235emen/

html2canvas(document.body, {  
  onrendered: function(canvas) {
    $("#page").hide();
    document.body.appendChild(canvas);
    window.print();
    $('canvas').remove();
    $("#page").show();
  }
});

Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:

<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
     <asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>

If you want to add it at a different index, maybe the last then try:

ListItem lst = new ListItem ( "Add New" , "0" );

DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);

You can also use REGEXP's synonym RLIKE as well.

For example:

SELECT *
FROM TABLE_NAME
WHERE COLNAME RLIKE 'REGEX1|REGEX2|REGEX3'

You have to dot source them:

. .\build_funtions.ps1
. .\build_builddefs.ps1

The other answers didn't work for me. I kept searching and found a blog post that covered how a team was running non-root inside of a docker container.

Here's the TL;DR version:

RUN apt-get update \
 && apt-get install -y sudo

RUN adduser --disabled-password --gecos '' docker
RUN adduser docker sudo
RUN echo '%sudo ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers

USER docker

# this is where I was running into problems with the other approaches
RUN sudo apt-get update 

I was using FROM node:9.3 for this, but I suspect that other similar container bases would work as well.

tnsping xe --if you have installed express edition
tnsping orcl --or if you have installed enterprise or standard edition then try to run

sqlplus  --this will prompt for user
hr --user that you have created or use system
password --inputted at the time of user creation for hr, or put the password given at the time of setup for system user
hope this will connect if db run at your localhost.
--if db host in a remote host then you must use tns name for our example orcl or xe
try this to connect remote
hr/pass...@orcl or hr/pass...@xe --based on what edition you have installed

You can't do that, because GetFiles only accepts a single search pattern. Instead, you can call GetFiles with no pattern, and filter the results in code:

string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };

FileInfo[] files =
    dinfo.GetFiles()
         .Where(f => extensions.Contains(f.Extension.ToLower()))
         .ToArray();

If you're working with .NET 4, you can use the EnumerateFiles method to avoid loading all FileInfo objects in memory at once:

string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };

FileInfo[] files =
    dinfo.EnumerateFiles()
         .Where(f => extensions.Contains(f.Extension.ToLower()))
         .ToArray();

So i tried the above :javascript which works :) However HAML wraps the generated code in CDATA like so:

<script type="text/javascript">
  //<![CDATA[
    $(document).ready( function() {
       $('body').addClass( 'test' );
    } );
  //]]>
</script>

The following HAML will generate the typical tag for including (for example) typekit or google analytics code.

 %script{:type=>"text/javascript"}
  //your code goes here - dont forget the indent!

1. Everything is encoded by default!!! This is pretty huge.

2. Declarative helpers can be compiled so you don't need to do anything special to share them. I think they will replace .ascx controls to some extent. You have to jump through some hoops to use an .ascx control in another project.

3. You can make a section required which is nice.

You have to replace the values one by one such as in a for-loop or copying another array over another such as using memcpy(..) or std::copy

e.g.

for (int i = 0; i < arrayLength; i++) {
    array[i] = newValue[i];
}

Take care to ensure proper bounds-checking and any other checking that needs to occur to prevent an out of bounds problem.

The issue is caused by the DNS failing to resolve the hostname. Try using the IP address instead of the "computer name".

tee is perfect for this, but this will also do the job

Changing an image is easy, but how do you change it back to the original size after it has been changed? You may try this to change all images in a document back to the original size:

var i,L=document.images.length;
for(i=0;i<L;++i){
 document.images[i].style.height = 'auto'; //setting CSS value
 document.images[i].style.width = 'auto'; //setting CSS value
// document.images[i].height = ''; (don't need this, would be setting img.attribute)
// document.images[i].width = ''; (don't need this, would be setting img.attribute)
}

numpy.ndarray() is a class, while numpy.array() is a method / function to create ndarray.

In numpy docs if you want to create an array from ndarray class you can do it with 2 ways as quoted:

1- using array(), zeros() or empty() methods: Arrays should be constructed using array, zeros or empty (refer to the See Also section below). The parameters given here refer to a low-level method (ndarray(…)) for instantiating an array.

2- from ndarray class directly: There are two modes of creating an array using __new__: If buffer is None, then only shape, dtype, and order are used. If buffer is an object exposing the buffer interface, then all keywords are interpreted.

The example below gives a random array because we didn't assign buffer value:

np.ndarray(shape=(2,2), dtype=float, order='F', buffer=None)

array([[ -1.13698227e+002,   4.25087011e-303],
       [  2.88528414e-306,   3.27025015e-309]])         #random

another example is to assign array object to the buffer example:

>>> np.ndarray((2,), buffer=np.array([1,2,3]),
...            offset=np.int_().itemsize,
...            dtype=int) # offset = 1*itemsize, i.e. skip first element
array([2, 3])

from above example we notice that we can't assign a list to "buffer" and we had to use numpy.array() to return ndarray object for the buffer

Conclusion: use numpy.array() if you want to make a numpy.ndarray() object"

I faced this problem a few days ago - the solution for me was to use .bind() to bind the required function to the dynamically created link.

var catLink = $('<a href="#" id="' + i + '" class="lnkCat">' + category.category + '</a>');
catLink.bind("click", function(){
 $.categories.getSubCategories(this);
});

getSubCategories : function(obj) {
 //do something
}

I hope this helps.

SELECT CONVERT(CAST(column as BINARY) USING utf8) as column FROM table 

You can do like

$timeout(function() {
   angular.element('#btn2').triggerHandler('click');
});

Try using-

psql -d postgres

I was also facing the same issue when I ran psql

Out-File defaults to unicode encoding which is why you are seeing the behavior you are. Use -Encoding Ascii to change this behavior. In your case

Out-File -Encoding Ascii -append textfile.txt. 

Add-Content uses Ascii and also appends by default.

"This is a test" | Add-Content textfile.txt.

As for the lack of newline: You did not send a newline so it will not write one to file.

Run it at the command line with osql, see here:

http://metrix.fcny.org/wiki/display/dev/How+to+execute+a+.SQL+script+using+OSQL

Try this

Option Explicit

Sub UniqueValues()
Dim ws As Worksheet
Dim uniqueRng As Range
Dim myCol As Long

myCol = 5 '<== set it as per your needs
Set ws = ThisWorkbook.Worksheets("unique") '<== set it as per your needs

Set uniqueRng = GetUniqueValues(ws, myCol)

End Sub


Function GetUniqueValues(ws As Worksheet, col As Long) As Range
Dim firstRow As Long

With ws
    .Columns(col).RemoveDuplicates Columns:=Array(1), header:=xlNo

    firstRow = 1
    If IsEmpty(.Cells(1, col)) Then firstRow = .Cells(1, col).End(xlDown).row

    Set GetUniqueValues = Range(.Cells(firstRow, col), .Cells(.Rows.Count, col).End(xlUp))
End With

End Function

it should be quite fast and without the drawback NeepNeepNeep told about

As Brad Wilson states in his answer here:

ModelState.IsValid tells you if any model errors have been added to ModelState.

The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.

Try using :-

if (!ModelState.IsValid)
{
    var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));

    // Breakpoint, Log or examine the list with Exceptions.
}

If it helps catching you the error. Courtesy this and this

In Case if you want programmatically

public static Drawable getStorkLineDrawable(@ColorInt int colorStrok, int    iSize, int left, int top, int right, int bottom)

{
    GradientDrawable gradientDrawable = new GradientDrawable();
    gradientDrawable.setShape(GradientDrawable.RECTANGLE);
    gradientDrawable.setStroke(iSize, colorStrok);
    LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{gradientDrawable});
    layerDrawable.setLayerInset(0, left, top, right, bottom);
    return layerDrawable;
}

call this method like

  Drawable yourLineDrawable=  getStorkLineDrawable(yourColor, iSize, -iSize, -iSize, -iSize, 0);

Not all parameters are supported by all cameras - actually, they are one of the most troublesome part of the OpenCV library. Each camera type - from android cameras to USB cameras to professional ones offer a different interface to modify its parameters. There are many branches in OpenCV code to support as many of them, but of course not all possibilities are covered.

What you can do is to investigate your camera driver, write a patch for OpenCV and send it to code.opencv.org. This way others will enjoy your work, the same way you enjoy others'.

There is also a possibility that your camera does not support your request - most USB cams are cheap and simple. Maybe that parameter is just not available for modifications.

If you are sure the camera supports a given param (you say the camera manufacturer provides some code) and do not want to mess with OpenCV, you can wrap that sample code in C++ with boost::python, to make it available in Python. Then, enjoy using it.

I know this question is a bit old, but this is something simple that works for me very well to delete images off my project I'm working on.

unlink(dirname(__FILE__) . "/img/tasks/" . 'image.jpg');

The dirname(__FILE__) section prints out the base path to your project. The /img/tasks/ are two folders down from my base path. And finally, there's my image I want to delete which you can make into anything you need to.

With this I have not had any problem getting to my files on my server and deleting them.

Just in case commands in previous answers doesn't work, Try this: dat.dropna(subset=['x'], inplace = True)

I had the same problem, and it was caused by line for insecured registry in: /etc/default/docker

If element is not clickable and overlay issue is ocuring we use arguments[0].click().

WebElement ele = driver.findElement(By.xpath("//div[@class='input-group-btn']/input")); JavascriptExecutor executor = (JavascriptExecutor)driver; executor.executeScript("arguments[0].click();", ele);

I got the same error with vlc component when i changed the framework from 4.5 to 4. but it worked for me when I changed the platform from Any CPU to x86.

Try setting core.autocrlf value like this :

git config --global core.autocrlf true

have you tried changing the dataType in your ajax request from jsonp to json? that fixed it in my case.

Heroku treats logs as time-ordered streams of events. Accessing *.log files on the filesystem is not recommended in such an environment for a variety of reasons.

First, if your app has more than one dyno then each log file only represents a partial view into the events of your app. You would have to manually aggregate all the files to get the full view.

Second, the filesystem on Heroku is ephemeral meaning whenever your dyno is restarted or moved (which happens about once a day)the log files are lost. So you only get at most a day's view into that single dyno's logs.

Finally, on the Cedar stack running heroku console or even heroku run bash does not connect you to a currently running dyno. It spawns a new one specifically for the bash command. This is called a one-off process. As such, you won't find the log files for your other dynos that are running the actual http processes on the one spawned for heroku run.

Logging, and visibility in general, is a first-class citizen on Heroku and there are several tools that address these issues. First, to see a real-time stream of application events across all dynos and all layers of the application/stack use the heroku logs -t command to tail output to your terminal.

$ heroku logs -t
2010-09-16T15:13:46-07:00 app[web.1]: Processing PostController#list (for 208.39.138.12 at 2010-09-16 15:13:46) [GET]

This works great for observing the behavior of your application right now. If you want to store the logs for longer periods of time you can use one of the many logging add-ons that provide log retention, alerting and triggers.

Lastly, if you want to store the log files yourself you can setup your own syslog drain to receive the stream of events from Heroku and post-process/analyze yourself.

Summary: Don't use heroku console or heroku run bash to view static log files. Pipe into Heroku's stream of log events for your app using heroku logs or a logging add-on.

If you frequently use a large number of exceptions, you can pre-define a tuple, so you don't have to re-type them many times.

#This example code is a technique I use in a library that connects with websites to gather data

ConnectErrs  = (URLError, SSLError, SocketTimeoutError, BadStatusLine, ConnectionResetError)

def connect(url, data):
    #do connection and return some data
    return(received_data)

def some_function(var_a, var_b, ...):
    try: o = connect(url, data)
    except ConnectErrs as e:
        #do the recovery stuff
    blah #do normal stuff you would do if no exception occurred

NOTES:

1. If you, also, need to catch other exceptions than those in the pre-defined tuple, you will need to define another except block.

2. If you just cannot tolerate a global variable, define it in main() and pass it around where needed...

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

DocumentElement is the root node of the document so childNodes[1] doesn't exist in that document. childNodes[0] would be the <Settings> node

struct.pack('B' * len(integers), *integers)

*sequence means "unpack sequence" - or rather, "when calling f(..., *args ,...), let args = sequence".

Use this method, you just have to pass the InputStream

public String readIt(InputStream is) {
    if (is != null) {
        BufferedReader reader = new BufferedReader(new InputStreamReader(is, "utf-8"), 8);

        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            sb.append(line).append("\n");
        }
        is.close();
        return sb.toString();
    }
    return "error: ";
}

The syntax of the query is as follows:

Alter table <table name> rename column <column name> to <new column name>;

Example:

Alter table employee rename column eName to empName;

To rename a column name without space to a column name with space:

Alter table employee rename column empName to "Emp Name";

To rename a column with space to a column name without space:

Alter table employee rename column "emp name" to empName;

127.0.0.1 restricts access on every interface on port 8000 except development computer. change it to 0.0.0.0:8000 this will allow connection from curl.

There are a lot of good options for your case here. Still you should considering using the POST body.

The query string is perfect for your example, but if you have something more complicated, e.g. an arbitrary long list of items or boolean conditionals, you might want to define the post as a document, that the client sends over POST.

This allows a more flexible description of the search, as well as avoids the Server URL length limit.

Give ID to legend and apply css. Like add id hello to legend() the css is as follw:

#legend  legend {
  display: block;
  width: 100%;
  padding: 0;
  margin-bottom: 20px;
  font-size: 21px;
  line-height: inherit;
  color: #333333;
  border: 0;
  border-bottom: 1px solid #e5e5e5;
}

Suppose cellspcing / cellpadding / border-spacing property did not worked, you can use the code as follow.

<div class="form-group">
  <table width="100%" cellspacing="2px" style="border-spacing: 10px;">
    <tr>                        
      <td width="47%">
        <input type="submit" class="form-control btn btn-info" id="submit" name="Submit" />
      </td>
      <td width="5%"></td>
      <td width="47%">
        <input type="reset" class="form-control btn btn-info" id="reset" name="Reset" />
      </td>
    </tr>
  </table>
</div>

I've tried and got succeed while seperate the button by using table-width and make an empty td as 2 or 1% it doesn't return more different.

Typically one uses an abstract class to provide some incomplete functionality that will be fleshed out by concrete subclasses. It may provide methods that are used by its subclasses; it may also represent an intermediate node in the class hierarchy, to represent a common grouping of concrete subclasses, distinguishing them in some way from other subclasses of its superclass. Since an interface can't derive from a class, this is another situation where a class (abstract or otherwise) would be necessary, versus an interface.

A good rule of thumb is that only leaf nodes of a class hierarchy should ever be instantiated. Making non-leaf nodes abstract is an easy way of ensuring that.

Sooner or later you will have property with special character. You can either use index or combination of index and property.

dynamic jsonObject = new JObject();
jsonObject["Create-Date"] = DateTime.Now; //<-Index use
jsonObject.Album = "Me Against the world"; //<- Property use
jsonObject["Create-Year"] = 1995; //<-Index use
jsonObject.Artist = "2Pac"; //<-Property use

Not necessarily better, but since it's nice to have options here's how to do it using Jinja statements:

- debug:
    msg: "{% for address in network.addresses.private_man %}\
        {% if address.type == 'fixed' %}\
          {{ address.addr }}\
        {% endif %}\
      {% endfor %}"

Or if you prefer to put it all on one line:

- debug:
    msg: "{% for address in network.addresses.private_man if address.type == 'fixed' %}{{ address.addr }}{% endfor %}"

Which returns:

ok: [localhost] => {
    "msg": "172.16.1.100"
}

There's a difference between an empty string "" and an undefined variable. You should be checking whether or not theHref contains a defined string, rather than its lenght:

if(theHref){
   // ---
}

If you still want to check for the length, then do this:

if(theHref && theHref.length){
   // ...
}

If you're using Joda-Time (and there are lots of good reasons to - a simple, intuitive API and thread-safety) then you can do this trivially:

(new LocalDate()).plusDays(5);

to give 5 days from today, for example.

EDIT: My current advice would be to now use the Java 8 date/time api

The reason why things aren't stopping for you is because the process (doInBackground()) runs until it is finished. Therefore you should check if the thread is cancelled or not before doing stuff:

if(!isCancelled()){
// Do your stuff
}

So basically, if the thread is not cancelled, do it, otherwise skip it :) Could be useful to check for this some times during your operation, especially before time taking stuff.

Also it could be useful to "clean up" alittle in

onCancelled();

The simplest method is to run your program (unmodified) in Cygwin console.

The second simplest method is to run you program (also unmodified) in the ordinary Windows console, pipelining its output through tee.exe (from Cygwin or Git distribution). Tee.exe will recognize the escape codes and call appropriate WinAPI functions.

Something like:

java MyClass | tee.exe log.txt
java MyClass | tee.exe /dev/null

Suppose you have df with columns A B C.

The most simple way is:

df = df.reindex(['B','C','A'], axis=1)

After some additional searching (new search terms inspired by gbn's answer and u07ch's comment on KMike's answer) I found this, which completed successfully in 2 seconds:

ALTER DATABASE <dbname> SET OFFLINE WITH ROLLBACK IMMEDIATE

(Update)

When this still fails with the following error, you can fix it as inspired by this blog post:

ALTER DATABASE failed because a lock could not be placed on database 'dbname' Try again later.

you can run the following command to find out who is keeping a lock on your database:

EXEC sp_who2

And use whatever SPID you find in the following command:

KILL <SPID>

Then run the ALTER DATABASE command again. It should now work.

Installing fail2ban package on Debian, looks like it's hardcoded to install on /usr/lib/python3/dist-packages/fail2ban a path not on python3 sys.path.

so, instead of just copying, I (bash) linked the library to newer versions.
Future updates to the original app, will also be automatically applied to the linked versions.

We have two commands, first is "condition_command", second is "result_command". If we need run "result_command" when "condition_command" is successful (errorlevel=0):

condition_command && result_command

If we need run "result_command" when "condition_command" is fail:

condition_command || result_command

Therefore for run "some_command" in case when we have "string" in the file "status.txt":

find "string" status.txt 1>nul && some_command

in case when we have not "string" in the file "status.txt":

find "string" status.txt 1>nul || some_command

The problem is that even JavaScript does not see the option element being hovered. This is just to put emphasis on how it's not going to be solved (any time soon at least) by using just CSS:

window.onmouseover = function(e)
{
 console.log(e.target.nodeName);
}

The only way to resolve this issue (besides waiting a millennia for browser vendors to fix bugs, let alone one that afflicts what you're trying to do) is to replace the drop-down menu with your own HTML/XML using JavaScript. This would likely involve the use of replacing the select element with a ul element and the use of a radio input element per li element.

Xcode Workspace vs Project

1. What is the difference between the two of them?

Workspace is a set of projects

2. What are they responsible for?

Workspace is responsible for dependencies between projects. Project is responsible for the source code.

3. Which one of them should I work with when I'm developing my Apps in team/alone?

You choice should depends on a type of your project. For example if your project relies on CocoaPods dependency manager it creates a workspace.

4. Is there anything else I should be aware of in matter of these two files?

A competitor of workspace is cross-project references^[About]

According to official documentation https://keras.io/getting-started/faq/#how-can-i-install-hdf5-or-h5py-to-save-my-models-in-keras

you can do :

first test if you have h5py installed by running the

import h5py

if you dont have errors while importing h5py you are good to save:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

If you need to install h5py http://docs.h5py.org/en/latest/build.html

Changed your validation function to this

Another dplyr answer. If your variables have some common naming structure, you might try starts_with(). For example

library(dplyr)
df <- data.frame(var1 = rnorm(5), var2 = rnorm(5), var3 = rnorm (5), 
                 var4 = rnorm(5), char1 = rnorm(5), char2 = rnorm(5))
df
#        var2      char1        var4       var3       char2       var1
#1 -0.4629512 -0.3595079 -0.04763169  0.6398194  0.70996579 0.75879754
#2  0.5489027  0.1572841 -1.65313658 -1.3228020 -1.42785427 0.31168919
#3 -0.1707694 -0.9036500  0.47583030 -0.6636173  0.02116066 0.03983268
df1 <- df %>% select(-starts_with("char"))
df1
#        var2        var4       var3       var1
#1 -0.4629512 -0.04763169  0.6398194 0.75879754
#2  0.5489027 -1.65313658 -1.3228020 0.31168919
#3 -0.1707694  0.47583030 -0.6636173 0.03983268

If you want to drop a sequence of variables in the data frame, you can use :. For example if you wanted to drop var2, var3, and all variables in between, you'd just be left with var1:

df2 <- df1 %>% select(-c(var2:var3) )  
df2
#        var1
#1 0.75879754
#2 0.31168919
#3 0.03983268

Check it out in this demo fiddle, go ahead and change the dropdown or default values in the code.

Setting the passenger.Title with a value that equals to a title.Value should work.

View:

<select [(ngModel)]="passenger.Title">
    <option *ngFor="let title of titleArray" [value]="title.Value">
      {{title.Text}}
    </option>
</select>

TypeScript used:

class Passenger {
  constructor(public Title: string) { };
}
class ValueAndText {
  constructor(public Value: string, public Text: string) { }
}

...
export class AppComponent {
    passenger: Passenger = new Passenger("Lord");

    titleArray: ValueAndText[] = [new ValueAndText("Mister", "Mister-Text"),
                                  new ValueAndText("Lord", "Lord-Text")];

}

This works for me: View view is your editText, spinner...etc. And int drawable is your drawable route example (R.drawable.yourDrawable)

 public void verifyDrawable (View view, int drawable){

        int sdk = Build.VERSION.SDK_INT;

        if(sdk < Build.VERSION_CODES.JELLY_BEAN) {
            view.setBackgroundDrawable(
                    ContextCompat.getDrawable(getContext(),drawable));
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            view.setBackground(getResources().getDrawable(drawable));
        }    
    }

This solution is for Ruby on Rails 3.x and a js.erb file that rebuilds part of the DOM including the modal. It works regardless if the ajax call came from the modal or from a different part of the page.

if ($("#my-modal").attr("aria-hidden") === "false") {
  $("#my-modal").modal('hide').on('hidden.bs.modal', function (event) {
    functionThatEndsUpDestroyingTheDOM();
  });
} else {
  functionThatEndsUpDestroyingTheDOM();
}

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

Perhaps storing a blog post -> comments relation in a non-relational database is not really the best design.

You should probably store comments in a separate collection to blog posts anyway.

[edit]

See comments below for further discussion.

There are many fine ways to get this done, which others have already suggestioned. Following along the "get Excel data via SQL track", here are some pointers.

1. Excel has the "Data Connection Wizard" which allows you to import or link from another data source or even within the very same Excel file.

2. As part of Microsoft Office (and OS's) are two providers of interest: the old "Microsoft.Jet.OLEDB", and the latest "Microsoft.ACE.OLEDB". Look for them when setting up a connection (such as with the Data Connection Wizard).

3. Once connected to an Excel workbook, a worksheet or range is the equivalent of a table or view. The table name of a worksheet is the name of the worksheet with a dollar sign ("$") appended to it, and surrounded with square brackets ("[" and "]"); of a range, it is simply the name of the range. To specify an unnamed range of cells as your recordsource, append standard Excel row/column notation to the end of the sheet name in the square brackets.

4. The native SQL will (more or less be) the SQL of Microsoft Access. (In the past, it was called JET SQL; however Access SQL has evolved, and I believe JET is deprecated old tech.)

5. Example, reading a worksheet: SELECT * FROM [Sheet1$]

6. Example, reading a range: SELECT * FROM MyRange

7. Example, reading an unnamed range of cells: SELECT * FROM [Sheet1$A1:B10]

8. There are many many many books and web sites available to help you work through the particulars.

=== Further notes ===

By default, it is assumed that the first row of your Excel data source contains column headings that can be used as field names. If this is not the case, you must turn this setting off, or your first row of data "disappears" to be used as field names. This is done by adding the optional HDR= setting to the Extended Properties of the connection string. The default, which does not need to be specified, is HDR=Yes. If you do not have column headings, you need to specify HDR=No; the provider names your fields F1, F2, etc.

A caution about specifying worksheets: The provider assumes that your table of data begins with the upper-most, left-most, non-blank cell on the specified worksheet. In other words, your table of data can begin in Row 3, Column C without a problem. However, you cannot, for example, type a worksheeet title above and to the left of the data in cell A1.

A caution about specifying ranges: When you specify a worksheet as your recordsource, the provider adds new records below existing records in the worksheet as space allows. When you specify a range (named or unnamed), Jet also adds new records below the existing records in the range as space allows. However, if you requery on the original range, the resulting recordset does not include the newly added records outside the range.

Data types (worth trying) for CREATE TABLE: Short, Long, Single, Double, Currency, DateTime, Bit, Byte, GUID, BigBinary, LongBinary, VarBinary, LongText, VarChar, Decimal.

Connecting to "old tech" Excel (files with the xls extention): Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyFolder\MyWorkbook.xls;Extended Properties=Excel 8.0;. Use the Excel 5.0 source database type for Microsoft Excel 5.0 and 7.0 (95) workbooks and use the Excel 8.0 source database type for Microsoft Excel 8.0 (97), 9.0 (2000) and 10.0 (2002) workbooks.

Connecting to "latest" Excel (files with the xlsx file extension): Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Excel2007file.xlsx;Extended Properties="Excel 12.0 Xml;HDR=YES;"

Treating data as text: IMEX setting treats all data as text. Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Excel2007file.xlsx;Extended Properties="Excel 12.0 Xml;HDR=YES;IMEX=1";

Check your namespaces. I had and issue with that. I found that out by adding another web service to the project to dup it like you did yours and noticed the namespace was different. I had renamed it at the beginning of the project and it looks like its persisted.

I think this is much easier :)

    private void btnLogin_Click(object sender, EventArgs e)
    {
        //this.Hide();
        //var mm = new MainMenu();
        //mm.FormClosed += (s, args) => this.Close();
        //mm.Show();

        this.Hide();
        MainMenu mm = new MainMenu();
        mm.Show();

"Fast Tips:

1) NEVER call System.gc() yourself. This has been propagated as a fix here, and it doesn't work. Do not do it. If you noticed in my explanation, before getting an OutOfMemoryError, the JVM already runs a garbage collection so there is no reason to do one again (its slowing your program down). Doing one at the end of your activity is just covering up the problem. It may causes the bitmap to be put on the finalizer queue faster, but there is no reason you couldn't have simply called recycle on each bitmap instead.

2) Always call recycle() on bitmaps you don't need anymore. At the very least, in the onDestroy of your activity go through and recycle all the bitmaps you were using. Also, if you want the bitmap instances to be collected from the dalvik heap faster, it doesn't hurt to clear any references to the bitmap.

3) Calling recycle() and then System.gc() still might not remove the bitmap from the Dalvik heap. DO NOT BE CONCERNED about this. recycle() did its job and freed the native memory, it will just take some time to go through the steps I outlined earlier to actually remove the bitmap from the Dalvik heap. This is NOT a big deal because the large chunk of native memory is already free!

4) Always assume there is a bug in the framework last. Dalvik is doing exactly what its supposed to do. It may not be what you expect or what you want, but its how it works. "

There's 3 ways to clear file input with javascript:

1. set value property to empty or null.

   Works for IE11+ and other modern browsers.

2. Create an new file input element and replace the old one.

   The disadvantage is you will lose event listeners and expando properties.

3. Reset the owner form via form.reset() method.

   To avoid affecting other input elements in the same owner form, we can create an new empty form and append the file input element to this new form and reset it. This way works for all browsers.

I wrote a javascript function. demo: http://jsbin.com/muhipoye/1/

function clearInputFile(f){
    if(f.value){
        try{
            f.value = ''; //for IE11, latest Chrome/Firefox/Opera...
        }catch(err){ }
        if(f.value){ //for IE5 ~ IE10
            var form = document.createElement('form'),
                parentNode = f.parentNode, ref = f.nextSibling;
            form.appendChild(f);
            form.reset();
            parentNode.insertBefore(f,ref);
        }
    }
}

You may be using old version of Mysql but surely you can use

 DELETE FROM konta WHERE taken <> ''

But there are many other options available. You can try the following ones

DELETE * from konta WHERE strcmp(taken, '') <> 0;

DELETE * from konta where NOT (taken = '');

USE style="max-width:90%;"

<select name=countries  style="max-width:90%;">

special_func to avoid try-except repetition:

def special_func(test_case_dict):
    final_dict = {}
    exception_dict = {}

    def try_except_avoider(test_case_dict):

        try:
            for k,v in test_case_dict.items():
                final_dict[k]=eval(v) #If no exception evaluate the function and add it to final_dict

        except Exception as e:
            exception_dict[k]=e #extract exception
            test_case_dict.pop(k)
            try_except_avoider(test_case_dict) #recursive function to handle remaining functions

        finally:  #cleanup
            final_dict.update(exception_dict)
            return final_dict #combine exception dict and  final dict

    return try_except_avoider(test_case_dict) 

Run code:

def add(a,b):
    return (a+b)
def sub(a,b):
    return (a-b)
def mul(a,b):
    return (a*b)

case = {"AddFunc":"add(8,8)","SubFunc":"sub(p,5)","MulFunc":"mul(9,6)"}
solution = special_func(case)

Output looks like:

{'AddFunc': 16, 'MulFunc': 54, 'SubFunc': NameError("name 'p' is not defined")}

To convert to variables:

locals().update(solution)

Variables would look like:

AddFunc = 16, MulFunc = 54, SubFunc = NameError("name 'p' is not defined")

I had the same error after moving to a new laptop (Windows 10). In addition to setting Copy Local to true as mentioned above, I had to install the Crystal Reports 32-bit runtime engine for .Net Framework, even though everything else is set to run in a 64-bit environment. Hope that helps.

Turns out that YUI's reset CSS strips the list style from 'ul li' instead of just 'ul', which is why setting it just in 'ul' never worked.

Yet another reason (not for this case, but maybe it'll save some nerves for someone) is that in PHP 5.5 short open tags <? phpinfo(); ?> are disabled by default.

So the PHP interpreter would process code within short tags as plain text. In previous versions PHP this feature was enable by default. So the new behaviour can be a little bit mysterious.

If on another occasion you're synchronising a Collection rather than a String, perhaps you're be iterating over the collection and are worried about it mutating, Java 5 offers:

• CopyOnWriteArrayList
• CopyOnWriteArraySet

A function uses the globals of the module it's defined in. Instead of setting a = 3, for example, you should be setting module1.a = 3. So, if you want cur available as a global in utilities_module, set utilities_module.cur.

A better solution: don't use globals. Pass the variables you need into the functions that need it, or create a class to bundle all the data together, and pass it when initializing the instance.

It's not in standard C, so the behavior is undefined.

Some implementation uses it to clear stdin buffer.

From C11 7.21.5.2 The fflush function, fflush works only with output/update stream, not input stream.

If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.

I'm just learning docker and this got me as well. I stopped the container with that name already and therefore I thought I could run a new container with that name.

Not the case. Just because the container is stopped, doesn't mean it can't be started again, and it keeps all the same parameters that it was created with (including the name).

when I ran docker ps -a that's when I saw all the dummy test containers I created while I was playing around.

No problem, since I don't want those any more I just did docker rm containername at which point my new container was allowed to run with the old name.

Ah, and now that I finish writing this answer, I see Slawosz's comment on Walt Howard's answer above suggesting the use of docker ps -a

If your column is of type DATE (as you say), then you don't need to convert it into a string first (in fact you would convert it implicitly to a string first, then explicitly to a date and again explicitly to a string):

SELECT TO_CHAR(COL1, 'mm/dd/yyyy') FROM TABLE1

The date format your seeing for your column is an artifact of the tool your using (TOAD, SQL Developer etc.) and it's language settings.

I don't know if it's wise to do so, but you can just write

"filesizecounter: " + $filesizecounter

And it should output:

filesizecounter: value

I always use something like the following:

public static String GetTimestamp(this DateTime value)
{
    return value.ToString("yyyyMMddHHmmssfff");
}

This will give you a string like 200905211035131468, as the string goes from highest order bits of the timestamp to lowest order simple string sorting in your SQL queries can be used to order by date if you're sticking values in a database
