after all these good examples adam shankman still can't make sense of it. I think you should open up some code and try it. The second you try a myStack.Push(1) and myStack.Pop(1) you really should get the picture. But by the looks of it, even that will be a challenge for you!

Greetings if i get you right you need a JavaScript function that doing it

function report(v) {
//To Do
  switch(v) {
    case "daily":
      //Do something
      break;
    case "monthly":
      //Do somthing
      break;
    }
  }

I tried the recommended solution that uses Application.ActivityLifecycleCallbacks and many others, but they didn't work as expected. Thanks to Sarge, I came up with a pretty easy and straightforward solution that I am describing below.

They key of the solution is the fact of understanding that if we have ActivityA and ActivityB, and we call ActivityB from ActivityA (and not call ActivityA.finish), then ActivityB's onStart() will be called before ActivityA onStop().

That's also the main difference between onStop() and onPause() that none did mention in the articles I read.

So based on this Activity's Lifecycle behavior, you can simply count how many times did onStart() and onPause() got called in your program. Note that for each Activity of your program, you must override onStart() and onStop(), in order to increment/decrement the static variable used for counting. Below is the code implementing this logic. Note that I am using a class that extends Application, so dont forget to declare on Manifest.xml inside Application tag: android:name=".Utilities", although it can be implemented using a simple custom class too.

public class Utilities extends Application
{
    private static int stateCounter;

    public void onCreate()
    {
        super.onCreate();
        stateCounter = 0;
    }

    /**
     * @return true if application is on background
     * */
    public static boolean isApplicationOnBackground()
    {
        return stateCounter == 0;
    }

    //to be called on each Activity onStart()
    public static void activityStarted()
    {
        stateCounter++;
    }

    //to be called on each Activity onStop()
    public static void activityStopped()
    {
        stateCounter--;
    }
}

Now on each Activity of our program, we should override onStart() and onStop() and increment/decrement as shown below:

@Override
public void onStart()
{
    super.onStart();
    Utilities.activityStarted();
}

@Override
public void onStop()
{
    Utilities.activityStopped();
    if(Utilities.isApplicationOnBackground())
    {
        //you should want to check here if your application is on background
    }
    super.onStop();
}

With this logic, there are 2 possible cases:

1. stateCounter = 0 : The number of stopped is equal with the number of started Activities, which means that the application is running on the background.
2. stateCounter > 0 : The number of started is bigger than the number of stopped, which means that the application is running on the foreground.

Notice: stateCounter < 0 would mean that there are more stopped Activities rather than started, which is impossible. If you encounter this case, then it means that you are not increasing/decreasing the counter as you should.

You are ready to go. You should want to check if your application is on background inside onStop().

Note that the % syntax for formatting strings is becoming outdated. If your version of Python supports it, you should write:

instr = "'{0}', '{1}', '{2}', '{3}', '{4}', '{5}', '{6}'".format(softname, procversion, int(percent), exe, description, company, procurl)

This also fixes the error that you happened to have.

You can do something like this:

 (SELECT
    name, games, goals
    FROM tblMadrid WHERE name = 'ronaldo')
 UNION
 (SELECT
    name, games, goals
    FROM tblBarcelona WHERE name = 'messi')
ORDER BY goals;

See, for example: https://dev.mysql.com/doc/refman/5.0/en/union.html

Use following property same as table and its fully dynamic:

ul {_x000D_
    width: 100%;_x000D_
    display: table;_x000D_
    table-layout: fixed; /* optional, for equal spacing */_x000D_
    border-collapse: collapse;_x000D_
}_x000D_
li {_x000D_
    display: table-cell;_x000D_
    text-align: center;_x000D_
    border: 1px solid pink;_x000D_
    vertical-align: middle;_x000D_
}

<ul>_x000D_
  <li>foo<br>foo</li>_x000D_
  <li>barbarbarbarbar</li>_x000D_
  <li>baz klxjgkldjklg </li>_x000D_
  <li>baz</li>_x000D_
  <li>baz lds.jklklds</li>_x000D_
</ul>

May be its solve your issue.

I was getting the same error on a restored database when I tried to insert a new record using the EntityFramework. It turned out that the Indentity/Seed was screwing things up.

Using a reseed command fixed it.

DBCC CHECKIDENT ('[Prices]', RESEED, 4747030);GO

One difference is for r+ if the files does not exist, it'll not be created and open fails. But in case of a+ the file will be created if it does not exist.

This isn't as straightforward as opening a plain text file and will require some sort of external module since nothing is built-in to do this. Here are some options:

http://www.python-excel.org/

If possible, you may want to consider exporting the excel spreadsheet as a CSV file and then using the built-in python csv module to read it:

http://docs.python.org/library/csv.html

var newObj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
var maxValue = Math.max(...Object.values(newObj))
var minValue = Math.min(...Object.values(newObj))

Wget currently only supports x-www-form-urlencoded data. --post-file is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example.

--post-data and --post-file work the same way: the only difference is that --post-data allows you to specify the data in the command line, while --post-file allows you to specify the path of the file that contain the data to send.

Here's the documentation:

 --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified data
           in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work in
           exactly the same way. In particular, they both expect content of the
           form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file. In
           particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.

Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN.

wget --post-data 'user=foo&password=bar' http://example.com/auth.php

Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.

I experienced this issue today and started searching on internet. In my case there was no table in my DB. I forgot to import the tables on the online server. I did it and all works fine.

I had the same problem. I use hyphenat plus the following macro:

\RequirePackage{hyphenat}
\RequirePackage{expl3}


% The following defs make sure words that contain an explicit `-` (hyphen) are still hyphenated the normal way, and double- and triple hyphens keep working the way they should. Just don't use a `-` as the last token of your document. Also note that `-` is now a macro that is not fully expandable

\ExplSyntaxOn

% latex2e doesn't like commands starting with 'end', apparently expl3 doesn't have any problems with it
\cs_new:Npn \hyphenfix_emdash:c {---}
\cs_new:Npn \hyphenfix_endash:c {--}

\cs_new:Npn \hyphenfix_discardnext:NN #1#2{#1}


\catcode`\-=\active

\cs_new_protected:Npn -{
    \futurelet\hyphenfix_nexttok\hyphenfix_i:w
}

\cs_new:Npn \hyphenfix_i:w {
    \cs_if_eq:NNTF{\hyphenfix_nexttok}{-}{
        %discard the next `-` token
        \hyphenfix_discardnext:NN{\futurelet\hyphenfix_nexttok\hyphenfix_ii:w}
    }{
        % from package hyphenat
        \hyp
    }
}

\cs_new:Npn \hyphenfix_ii:w {
    \cs_if_eq:NNTF{\hyphenfix_nexttok}{-}{
        \hyphenfix_discardnext:NN{\hyphenfix_emdash:c}
    }{
        \hyphenfix_endash:c
    }
}


\ExplSyntaxOff

Note that this uses the expl3 package from latex3.

It makes the - an active character that scans forward to see if it is followed by more dashes. If so, it stays a -, to make sure -- and --- keep working. If not, it becomes the \hyp command from hyphenat, enabling word breaks in the rest of the word. This is a generic solution that makes all words that contain explicit hyphens hyphenate normally.

Note that - becomes a macro that is not fully expandable, so try to include this after loading other packages that may not expect - to be a macro

Edit: This is my second version, the first version was less robust when a { or } followed a hyphen. This one is not, but unlike the first version the - in this version is not fully expandable.

According to PEP8, long lines should be placed in parentheses. When using parentheses, the lines can be broken up without using backslashes. You should also try to put the line break after boolean operators.

Further to this, if you're using a code style check such as pycodestyle, the next logical line needs to have different indentation to your code block.

For example:

if (abcdefghijklmnopqrstuvwxyz > some_other_long_identifier and
        here_is_another_long_identifier != and_finally_another_long_name):
    # ... your code here ...
    pass

After adding an item to a list, you can replace it by writing

list[someIndex] = new MyClass();

You can modify an existing item in the list by writing

list[someIndex].SomeProperty = someValue;

EDIT: You can write

var index = list.FindIndex(c => c.Number == someTextBox.Text);
list[index] = new SomeClass(...);

If you are supporting API 23 and above, you can now use the titleTextColor attribute to set the Toolbar's title color.

layout/toolbar.xml

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:titleTextColor="@color/colorPrimary"
        />

MyActivity.java

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar)
toolbar.setTitleTextColor(Color.WHITE);

By using the null-conditional operator (?.) you can get the HTTP status code with a single line of code:

 HttpStatusCode? status = (ex.Response as HttpWebResponse)?.StatusCode;

The variable status will contain the HttpStatusCode. When the there is a more general failure like a network error where no HTTP status code is ever sent then status will be null. In that case you can inspect ex.Status to get the WebExceptionStatus.

If you just want a descriptive string to log in case of a failure you can use the null-coalescing operator (??) to get the relevant error:

string status = (ex.Response as HttpWebResponse)?.StatusCode.ToString()
    ?? ex.Status.ToString();

If the exception is thrown as a result of a 404 HTTP status code the string will contain "NotFound". On the other hand, if the server is offline the string will contain "ConnectFailure" and so on.

(And for anybody that wants to know how to get the HTTP substatus code. That is not possible. It is a Microsoft IIS concept that is only logged on the server and never sent to the client.)

varchar, Don't store separating characters you may want to format the phone numbers differently for different uses. so store (619) 123-4567 as 6191234567 I work with phone directory data and have found this to be the best practice.

Option 1

Use the fact that a data.frame is a list of columns, then use do.call to recreate a data.frame.

do.call(data.frame,lapply(DT, function(x) replace(x, is.infinite(x),NA)))

Option 2 -- data.table

You could use data.table and set. This avoids some internal copying.

DT <- data.table(dat)
invisible(lapply(names(DT),function(.name) set(DT, which(is.infinite(DT[[.name]])), j = .name,value =NA)))

Or using column numbers (possibly faster if there are a lot of columns):

for (j in 1:ncol(DT)) set(DT, which(is.infinite(DT[[j]])), j, NA)

Timings

# some `big(ish)` data
dat <- data.frame(a = rep(c(1,Inf), 1e6), b = rep(c(Inf,2), 1e6), 
                  c = rep(c('a','b'),1e6),d = rep(c(1,Inf), 1e6),  
                  e = rep(c(Inf,2), 1e6))
# create data.table
library(data.table)
DT <- data.table(dat)

# replace (@mnel)
system.time(na_dat <- do.call(data.frame,lapply(dat, function(x) replace(x, is.infinite(x),NA))))
## user  system elapsed 
#  0.52    0.01    0.53 

# is.na (@dwin)
system.time(is.na(dat) <- sapply(dat, is.infinite))
# user  system elapsed 
# 32.96    0.07   33.12 

# modified is.na
system.time(is.na(dat) <- do.call(cbind,lapply(dat, is.infinite)))
#  user  system elapsed 
# 1.22    0.38    1.60 


# data.table (@mnel)
system.time(invisible(lapply(names(DT),function(.name) set(DT, which(is.infinite(DT[[.name]])), j = .name,value =NA))))
# user  system elapsed 
# 0.29    0.02    0.31 

data.table is the quickest. Using sapply slows things down noticeably.

munmap(0xb7d28000, 4096) = 0
write(2, "OSError", 7) = 7

I've seen sloppy code that looks like this:

serrno = errno;
some_Syscall(...)
if (serrno != errno)
/* sound alarm: CATROSTOPHIC ERROR !!! */

You should check to see if this is what is happening in the python code. Errno is only valid if the proceeding system call failed.

String.split() works very good but has its own boundaries, like if you wanted to split a string as shown below based on single or double pipe (|) symbol, it doesn't work. In this situation you can use StringTokenizer.

ABC|IJK

Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package

import sun.misc.BASE64Encoder;

import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;

and then,

String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );

 public String getAuthantication(String username, String password) {
   String auth = new String(Base64.encode(username + ":" + password));
   return auth;
 }

I found a really easy solution: add to the mail command the modifier -aContent-Type:text/html.

In your case would be:

mail -aContent-Type:text/html -s "Built notification" [email protected] < /var/www/report.csv

I rather use Virtualenv to install such packages rather than the entire system, saves time and effort rather than building from source.

I use virtualenvwrapper

Windows user can download

pip install virtualenvwrapper-win

https://pypi.org/project/virtualenvwrapper-win/

Linux follow

pip install opencv-python

opencv-python

If processing a video is required

pip install opencv-contrib-python

opencv-contrib-python

If you do not need GUI in Opencv

pip install opencv-contrib-python-headless

opencv-contrib-python-headless

Font Awesome seems to be working fine for me in my android app. I did the following:

1. Copied fontawesome-webfont.ttf into my assests folder
2. Found the character entities for icons I wanted, using this page: http://fortawesome.github.io/Font-Awesome/cheatsheet/

3. Created an entry in strings.xml for each icon. Eg for a heart:

   <string name="icon_heart">&#xf004;</string>
   

4. Referenced said entry in the view of my xml layout:

    <Button
        android:id="@+id/like"
        style="?android:attr/buttonStyleSmall"
        ...
        android:text="@string/icon_heart" />
   

5. Loaded the font in my onCreate method and set it for the appropriate Views:

   Typeface font = Typeface.createFromAsset( getAssets(), "fontawesome-webfont.ttf" );
   ...
   Button button = (Button)findViewById( R.id.like );
   button.setTypeface(font);
   

Here are conversion method for both ways. this = instance of your class

public string ToXML()
    {
        using(var stringwriter = new System.IO.StringWriter())
        { 
            var serializer = new XmlSerializer(this.GetType());
            serializer.Serialize(stringwriter, this);
            return stringwriter.ToString();
        }
    }

 public static YourClass LoadFromXMLString(string xmlText)
    {
        using(var stringReader = new System.IO.StringReader(xmlText))
        {
            var serializer = new XmlSerializer(typeof(YourClass ));
            return serializer.Deserialize(stringReader) as YourClass ;
        }
    }

Capitalize the first character in the string

extension String {
    var capitalizeFirst: String {
        if self.characters.count == 0 {
            return self

        return String(self[self.startIndex]).capitalized + String(self.characters.dropFirst())
    }
}

One other way, using the splat operator:

*a, last = [1, 3, 4, 5]

STDOUT:
a: [1, 3, 4]
last: 5

It's simple, you need to get the Select field value and it cannot be "default".

if($('select').val()=='default'){
    alert('Please, choose an option');
    return false;
}

It would work as given below :

insert into Gengl_Del Select Tdate,DocNo,Book,GlCode,OpGlcode,Amt,Narration 
from Gengl where BOOK='" & lblBook.Caption & "' AND DocNO=" & txtVno.Text & ""

The correct and safe method for close the resources associated with JDBC this (taken from How to Close JDBC Resources Properly – Every Time):

Connection connection = dataSource.getConnection();
try {
    Statement statement = connection.createStatement();

    try {
        ResultSet resultSet = statement.executeQuery("some query");

        try {
            // Do stuff with the result set.
        } finally {
            resultSet.close();
        }
    } finally {
        statement.close();
    }
} finally {
    connection.close();
}

1. Open the config.inc.php file in the WAMP phpmyadmin directory

2. Change the line ['Servers'][$i]['password'] = '' to

   $cfg['Servers'][$i]['password'] = 'your_mysql_root_password';

3. Clear browser cookies

4. Then Restart all services on WAMP

This worked for me.

NB: the password to use has to be the MySQL password.....

As others have said, there is no way to do a single line comment legally in XML that comments out multiple lines, but, there are ways to make commenting out segments of XML easier.

Looking at the example below, if you add '>' to line one, the XmlTag will be uncommented. Remove the '>' and it's commented out again. This is the simplest way that I've seen to quickly comment/uncomment XML without breaking things.

<!-- --
<XmlTag variable="0" />
<!-- -->

The added benefit is that you only manipulate the top comment, and the bottom comment can just sit there forever. This breaks compatibility with SGML and some XML parsers will barf on it. So long as this isn't a permanent fixture in your XML, and your parsers accept it, it's not really a problem.

Stack Overflow's and Notepad++'s syntax highlighter treat it like a multi-line comment, C++'s Boost library treats it as a multi-line comment, and the only parser I've found so far that breaks is the one in .NET, specifically C#. So, be sure to first test that your tools, IDE, libraries, language, etc. accept it before using it.

If you care about SGML compatibility, simply use this instead:

<!-- -
<XmlTag variable="0" />
<!- -->

Add '->' to the top comment and a '-' to the bottom comment. The downside is having to edit the bottom comment each time, which would probably make it easier to just type in <!-- at the top and --> at the bottom each time.

I also want to mention that other commenters recommend using an XML editor that allows you to right-click and comment/uncomment blocks of XML, which is probably preferable over fancy find/replace tricks (it would also make for a good answer in itself, but I've never used such tools. I just want to make sure the information isn't lost over time). I've personally never had to deal with XML enough to justify having an editor fancier than Notepad++, so this is totally up to you.

If you don't have it at C:\Users\%USERNAME%\AppData\Local\Android (this is where most people have it) than it is possible you don't have it installed. Go to Tools > Android > SDK Manager and then click on "Android SDK." On the top of the SDK Manager it will list the SDK Location. Click edit. If you don't have Android SDK installed, it will give you the option to install it in certain location. Install it, and Android Studio should work!

Use the requests library, pretty print the results so you can better locate the keys/values you want to extract, and then use nested for loops to parse the data. In the example I extract step by step driving directions.

import json, requests, pprint

url = 'http://maps.googleapis.com/maps/api/directions/json?'

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)


data = requests.get(url=url, params=params)
binary = data.content
output = json.loads(binary)

# test to see if the request was valid
#print output['status']

# output all of the results
#pprint.pprint(output)

# step-by-step directions
for route in output['routes']:
        for leg in route['legs']:
            for step in leg['steps']:
                print step['html_instructions']

Manually add it when you build the query:

SELECT 'Site1' AS SiteName, t1.column, t1.column2
FROM t1

UNION ALL
SELECT 'Site2' AS SiteName, t2.column, t2.column2
FROM t2

UNION ALL
...

EXAMPLE:

DECLARE @t1 TABLE (column1 int, column2 nvarchar(1))
DECLARE @t2 TABLE (column1 int, column2 nvarchar(1))

INSERT INTO @t1
SELECT 1, 'a'
UNION SELECT 2, 'b'

INSERT INTO @t2
SELECT 3, 'c'
UNION SELECT 4, 'd'


SELECT 'Site1' AS SiteName, t1.column1, t1.column2
FROM @t1 t1

UNION ALL
SELECT 'Site2' AS SiteName, t2.column1, t2.column2
FROM @t2 t2

RESULT:

Most people have said it - Plain Old CLR Object (as opposed to the earlier POJO - Plain Old Java Object)

The POJO one came out of EJB, which required you to inherit from a specific parent class for things like value objects (what you get back from a query in an ORM or similar), so if you ever wanted to move from EJB (eg to Spring), you were stuffed.

POJO's are just classes which dont force inheritance or any attribute markup to make them "work" in whatever framework you are using.

POCO's are the same, except in .NET.

Generally it'll be used around ORM's - older (and some current ones) require you to inherit from a specific base class, which ties you to that product. Newer ones dont (nhibernate being the variant I know) - you just make a class, register it with the ORM, and you are off. Much easier.

I would think your own suggestion is correct, however the xml is not quite valid. If you are running the //book[title[@lang='it']] on <root>[Your"XML"Here]</root> then the free online xPath testers such as one here will find the expected result.

You could do this by Regular Expression as follows you could use this code

EditText et = (EditText) findViewById(R.id.editText);
String NumberPattern = "[0-9]+";
String Number = et.getText().toString();

if (Number.matches(NumberPattern) && s.length() > 0)
{ 
    //code for number
}
else
{
    //code for incorrect number pattern
}

Call JObject's ToString(Formatting.None) method.

Alternatively if you pass the object to the JsonConvert.SerializeObject method it will return the JSON without formatting.

In my case installing a new virtual device helped. Now I am using 1 device per app.

@ is used for an array.

In a subroutine or when you call a function in Perl, you may pass the parameter list. In that case, @_ is can be used to pass the parameter list to the function:

sub Average{

    # Get total number of arguments passed.
    $n = scalar(@_);
    $sum = 0;

    foreach $item (@_){

        # foreach is like for loop... It will access every
        # array element by an iterator
        $sum += $item;
    }

    $average = $sum / $n;

    print "Average for the given numbers: $average\n";
}

Function call

Average(10, 20, 30);

If you observe the above code, see the foreach $item(@_) line... Here it passes the input parameter.

for any1 using ie8 and dont want to use a plugin i've made something inspired by Rohit Azad and Bacotasan's blog, i just added a span using JS to show the selected value.

the html:

<div class="styled-select">
   <select>
      <option>Here is the first option</option>
      <option>The second option</option>
   </select>
   <span>Here is the first option</span>
</div>

the css (i used only an arrow for BG but you could put a full image and drop the positioning):

.styled-select div
{
    display:inline-block;
    border: 1px solid darkgray;
    width:100px;
    background:url("/Style Library/Nifgashim/Images/drop_arrrow.png") no-repeat 10px 10px;
    position:relative;
}

.styled-select div select
{
    height: 30px;
    width: 100px;
    font-size:14px;
    font-family:ariel;

    -moz-opacity: 0.00;
    opacity: .00;
    filter: alpha(opacity=00);
}

.styled-select div span
{
    position: absolute;
    right: 10px;
    top: 6px;
    z-index: -5;
}

the js:

$(".styled-select select").change(function(e){
     $(".styled-select span").html($(".styled-select select").val());
});

This is a very simple example of factorial with Recursion:

Factorials are a very easy maths concept. They are written like 5! and this means 5 * 4 * 3 * 2 * 1. So 6! is 720 and 4! is 24.

function factorial($number) { 

    if ($number < 2) { 
        return 1; 
    } else { 
        return ($number * factorial($number-1)); 
    } 
}

hope this is usefull for you. :)

Vim has a branch operator \& that is useful when searching for a line containing a set of words, in any order. Moreover, extending the set of required words is trivial.

For example,

/.*jack\&.*james

will match a line containing jack and james, in any order.

See this answer for more information on usage. I am not aware of any other regex flavor that implements branching; the operator is not even documented on the Regular Expression wikipedia entry.

You've got a couple regexes now which will do what you want, so that's adequately covered.

What hasn't been mentioned is why your attempt won't work: Inside a character class, $ (as well as ^, ., and /) has no special meaning, so [/$] matches either a literal / or a literal $ rather than terminating the regex (/) or matching end-of-line ($).

Map<String,Integer> hm = new HashMap<String, Integer>();
for(String i : animals) {
    Integer j = hm.get(i);
    hm.put(i,(j==null ? 1 : j+1));
}
for(Map.Entry<String, Integer> val : hm.entrySet()) {
    System.out.println(val.getKey()+" occurs : "+val.getValue()+" times");
}

Just agreeing with ffill method, but one extra info is that you can limit the forward fill with keyword argument limit.

>>> import pandas as pd    
>>> df = pd.DataFrame([[1, 2, 3], [None, None, 6], [None, None, 9]])

>>> df
     0    1   2
0  1.0  2.0   3
1  NaN  NaN   6
2  NaN  NaN   9

>>> df[1].fillna(method='ffill', inplace=True)
>>> df
     0    1    2
0  1.0  2.0    3
1  NaN  2.0    6
2  NaN  2.0    9

Now with limit keyword argument

>>> df[0].fillna(method='ffill', limit=1, inplace=True)

>>> df
     0    1  2
0  1.0  2.0  3
1  1.0  2.0  6
2  NaN  2.0  9

<div ng-controller="TestCtrl1">
    <div ng-controller="TestCtrl2">
      <!-- your code--> 
    </div> 
</div>

This works best in my case, where TestCtrl2 has it's own directives.

var testCtrl2 = $controller('TestCtrl2')

This gives me an error saying scopeProvider injection error.

   var testCtrl1ViewModel = $scope.$new();
   $controller('TestCtrl1',{$scope : testCtrl1ViewModel });
   testCtrl1ViewModel.myMethod(); 

This doesn't really work if you have directives in 'TestCtrl1', that directive actually have a different scope from this one created here. You end up with two instances of 'TestCtrl1'.

sort sorts inplace so returns nothing:

In [54]:
df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].unique()
a.sort()
a

Out[54]:
array([1, 2, 3, 6, 8], dtype=int64)

So you have to call print a again after the call to sort.

Eg.:

In [55]:
df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].unique()
a.sort()
print(a)

[1 2 3 6 8]

I created a bot to get User or GroupChat id, just send the /my_id to telegram bot @get_id_bot.

It does not only work for user chat ID, but also for group chat ID.

To get group chat ID, first you have to add the bot to the group, then send /my_id in the group.

Here's the link to the bot.

There is no task to download dependencies; they are downloaded on demand. To learn how to manage dependencies with Gradle, see "Chapter 8. Dependency Management Basics" in the Gradle User Guide.

CMP subtracts the operands and sets the flags. Namely, it sets the zero flag if the difference is zero (operands are equal).

TEST sets the zero flag, ZF, when the result of the AND operation is zero. If two operands are equal, their bitwise AND is zero when both are zero. TEST also sets the sign flag, SF, when the most significant bit is set in the result, and the parity flag, PF, when the number of set bits is even.

JE [Jump if Equals] tests the zero flag and jumps if the flag is set. JE is an alias of JZ [Jump if Zero] so the disassembler cannot select one based on the opcode. JE is named such because the zero flag is set if the arguments to CMP are equal.

So,

TEST %eax, %eax
JE   400e77 <phase_1+0x23>

jumps if the %eax is zero.

I got lucky and answered this in a comment to the question, but I'm posting a full answer for the sake of completeness and so we can mark this question as "Answered".

It depends on what you want to accomplish by sharing a controller; you can either share the same controller (though have different instances), or you can share the same controller instance.

Share a Controller

Two directives can use the same controller by passing the same method to two directives, like so:

app.controller( 'MyCtrl', function ( $scope ) {
  // do stuff...
});

app.directive( 'directiveOne', function () {
  return {
    controller: 'MyCtrl'
  };
});

app.directive( 'directiveTwo', function () {
  return {
    controller: 'MyCtrl'
  };
});

Each directive will get its own instance of the controller, but this allows you to share the logic between as many components as you want.

Require a Controller

If you want to share the same instance of a controller, then you use require.

require ensures the presence of another directive and then includes its controller as a parameter to the link function. So if you have two directives on one element, your directive can require the presence of the other directive and gain access to its controller methods. A common use case for this is to require ngModel.

^require, with the addition of the caret, checks elements above directive in addition to the current element to try to find the other directive. This allows you to create complex components where "sub-components" can communicate with the parent component through its controller to great effect. Examples could include tabs, where each pane can communicate with the overall tabs to handle switching; an accordion set could ensure only one is open at a time; etc.

In either event, you have to use the two directives together for this to work. require is a way of communicating between components.

Check out the Guide page of directives for more info: http://docs.angularjs.org/guide/directive

I face the same problem but that was after I had updated to appcompatv23.2.0. I tried all the above suggestions but dint work. Then I proceeded to my Gradle file and replaced:

dependencies {
compile 'com.android.support:appcompat-v7:23.2.0’
compile 'com.android.support:design:23.2.0'

}

with:

dependencies {
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
}

Rebuild the project and the issue was gone. It could be an issue with app compact v23.2.0, hopefully a better solution coming up so we can work with the new update.

Hope this helps. Thank you.

<select v-model="challan.warehouse_id">
<option value="">Select Warehouse</option>
<option v-for="warehouse in warehouses" v-bind:value="warehouse.id"  >
   {{ warehouse.name }}
</option>

Here "challan.warehouse_id" come from "challan" object you get from:

editChallan: function() {
    let that = this;
    axios.post('/api/challan_list/get_challan_data', {
    challan_id: that.challan_id
 })
 .then(function (response) {
    that.challan = response.data;
 })
 .catch(function (error) {
    that.errors = error;
  }); 
 }

Incase of arrays, the base address (i.e. address of the array) is the address of the 1st element in the array. Also the array name acts as a pointer.

Consider a row of houses (each is an element in the array). To identify the row, you only need the 1st house address.You know each house is followed by the next (sequential).Getting the address of the 1st house, will also give you the address of the row.

Incase of string literals(character arrays defined at declaration), they are automatically appended by \0.

printf prints using the format specifier and the address provided. Since, you use %s it prints from the 1st address (incrementing the pointer using arithmetic) until '\0'

Cleaned up the code (commented out the logger mostly) to make it run in my Eclipse environment.

    ReadXLSX test = new ReadXLSX(new FileInputStream(new File("./sample.xlsx")));

    System.out.println(test.getSheetsName());
    System.out.println(test.getNumberOfSheet());


}

}

All this ran like a charm, so my guess is you have an XLSX file that is 'corrupt' in one way or another. Try testing with other data.

I find that the the approved answer, request.env['PATH_INFO'], works for getting the base URL, but this does not always contain the full path if you have nested routes. You can use request.env['HTTP_REFERER'] to get the full path and then see if it matches a given route:

request.env['HTTP_REFERER'].match?(my_cool_path)

X <- c(1:3)*0

Maybe this is not the most efficient way to initialize a vector to zero, but this requires to remember only the c() function, which is very frequently cited in tutorials as a usual way to declare a vector.

As as side-note: To someone learning her way into R from other languages, the multitude of functions to do same thing in R may be mindblowing, just as demonstrated by the previous answers here.

I found this new way

bash $ ls -1  | xargs -i -t jar -tvf '{}'| grep Abstract
jar -tvf activation-1.1.jar
jar -tvf antisamy-1.4.3.jar
  2263 Thu Jan 13 21:38:10 IST 2011 org/owasp/validator/html/scan/AbstractAntiSamyScanner.class
...

So this lists the jar and the class if found, if you want you can give ls -1 *.jar or input to xargs with find command HTH Someone.

My case:

• I want to connect to a production WS server a www.mycompany.com/api/ws...
• using real credentials (a session cookie)...
• from a local page (localhost:8000).

Setting document.cookie = "sessionid=foobar;path=/" won't help as domains don't match.

The solution:

Add 127.0.0.1 wsdev.company.com to /etc/hosts.

This way your browser will use cookies from mycompany.com when connecting to www.mycompany.com/api/ws as you are connecting from a valid subdomain wsdev.company.com.

If you just need a good date-parsing function, I would look at date.js. It will take just about any date string you can throw at it, and return you a JavaScript Date object.

Once you have a Date object, you can call its getTime() method, which will give you milliseconds since January 1, 1970. Just divide that result by 1000 to get the unix timestamp value.

In code, just include date.js, then:

var unixtime = Date.parse("24-Nov-2009 17:57:35").getTime()/1000

You could do

<body onload="window.print()">
...
</body>

As addition to the answers above:

If you would like to delete those files

find $dir -size 0 -type f -delete

public ActionResult Index()
{
    ViewBag.Name = "Monjurul Habib";
    return View();
}

public ActionResult Index()
{
    ViewData["Name"] = "Monjurul Habib";
    return View();
} 

In View:

@ViewBag.Name 
@ViewData["Name"] 

This bit gives you ability to paginate using SQL Server, and newer versions of MySQL and carries the total number of rows in every row. Uses your pimary key to count number of unique rows.

WITH T AS
(  
  SELECT TABLE_ID, ROW_NUMBER() OVER (ORDER BY TABLE_ID) AS RN
  , (SELECT COUNT(TABLE_ID) FROM TABLE) AS TOTAL 
  FROM TABLE (NOLOCK)
)

SELECT T2.FIELD1, T2.FIELD2, T2.FIELD3, T.TOTAL 
FROM TABLE T2 (NOLOCK)
INNER JOIN T ON T2.TABLE_ID=T.TABLE_ID
WHERE T.RN >= 100
AND T.RN < 200

There is no way to get the old password back. Log into the SQL server management console as a machine or domain admin using integrated authentication, you can then change any password (including sa).

Start the SQL service again and use the new created login (recovery in my example) Go via the security panel to the properties and change the password of the SA account.

Now write down the new SA password.

Do it like this:

TextField(
  decoration: new InputDecoration.collapsed(
    hintText: 'Username'
  ),
),

or if you need other stuff like icon, set the border with InputBorder.none

InputDecoration(
    border: InputBorder.none,
    hintText: 'Username',
  ),
),

The App-Secret key should be kept private - but when releasing the app they can be reversed by some guys.

for those guys it will not hide, lock the either the ProGuard the code. It is a refactor and some payed obfuscators are inserting a few bitwise operators to get back the jk433g34hg3 String. You can make 5 -15 min longer the hacking if you work 3 days :)

Best way is to keep it as it is, imho.

Even if you store at server side( your PC ) the key can be hacked and printed out. Maybe this takes the longest? Anyhow it is a matter of few minutes or a few hours in best case.

A normal user will not decompile your code.

Every control that uses Collections to store data have SelectedValue, SelectedItem property. Examples of these controls are ListBox, Dropdown, RadioButtonList, CheckBoxList.

To be more specific if you literally want to retrieve Text of Selected Item then you can write:

ListBox1.SelectedItem.Text;

Your ListBox1 can also return Text using SelectedValue property if value has set to that before. But above is more effective way to get text.

Now, the value is something that is not visible to user but it is used mostly to store in database. We don't insert Text of ListBox1, however we can insert it also, but we used to insert value of selected item. To get value we can use

ListBox1.SelectedValue

dumpsys window windows gives more detail about the current activity:

adb shell "dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'"
  mCurrentFocus=Window{41d2c970 u0 com.android.launcher/com.android.launcher2.Launcher}
  mFocusedApp=AppWindowToken{4203c170 token=Token{41b77280 ActivityRecord{41b77a28 u0 com.android.launcher/com.android.launcher2.Launcher t3}}}

However in order to find the process ID (e.g. to kill the current activity), use dumpsys activity, and grep on "top-activity":

adb shell "dumpsys activity | grep top-activity"
    Proc # 0: fore  F/A/T  trm: 0 3074:com.android.launcher/u0a8 (top-activity)

adb shell "kill 3074"

 select persons.personsid,name,info.id,address
    -> from persons
    -> inner join persons on info.infoid = info.info.id;

Here are the differences. Note the newlines at the end.

Note that use of the backtick operator is identical to shell_exec().

Update: I really should explain that last one. Looking at this answer years later even I don't know why that came out blank! Daniel explains it above -- it's because exec only returns the last line, and ifconfig's last line happens to be blank.

As per my Answer here: https://stackoverflow.com/questions/6313126/how-to-remove-a-directory-in-my-github-repository

To remove folder/directory or file only from git repository and not from the local try 3 simple steps.

Steps to remove directory

git rm -r --cached File-or-FolderName
git commit -m "Removed folder from repository"
git push origin master

Steps to ignore that folder in next commits

To ignore that folder from next commits make one file in root named .gitignore and put that folders name into it. You can put as many as you want

.gitignore file will be look like this

/FolderName

Have you tried loading the socket.io script not from a relative URL?

You're using:

<script src="socket.io/socket.io.js"></script>

And:

socket.connect('http://127.0.0.1:8080');

You should try:

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

And:

socket.connect('http://localhost:8080');

Switch localhost:8080 with whatever fits your current setup.

Also, depending on your setup, you may have some issues communicating to the server when loading the client page from a different domain (same-origin policy). This can be overcome in different ways (outside of the scope of this answer, google/SO it).

The answer to the question is not deleting the rows from a table but it is the the tempDB space that is being taken up due to an active transaction. this happens mostly when there is a merge (upsert) is being run where we try to insert update and delete the transactions. The only option is is to make sure the DB is set to simple recovery model and also increase the file to the maximum space (Add an other file group). Although this has its own advantages and disadvantages these are the only options.

The other option that you have is to split the merge(upsert) into two operations. one that does the insert and the other that does the update and delete.

STEP 1

Go to properties of your project ( with Alt+Enter or righ-click )

STEP 2

check on Apache Tomcat v7.0 under Targeted Runtime and it works.

LE: I just remembered this was about using Google Maps, so my answer doesn't really answer the initial question, but I hope some people will save hours/days banging their heads on their desks if they have the same issue with Play Game Services.

I too had this incredibly cryptic error. It wasn't anything related to location services for me, but with not properly reading the documentation, more precisely step 3, where it says to add the following to your AndroidManifest.xml:

<meta-data android:name="com.google.android.gms.games.APP_ID"
    android:value="@string/app_id" />

You should obviously also have the following in AndroidManifest.xml

<meta-data android:name="com.google.android.gms.version"
   android:value="@integer/google_play_services_version"/>

I was using the BaseGameActivity they suggest to use when you want to implement game services so I was a bit surprised it didn't work straight away. I did create a dedicated module for a copy of the google-play-services_lib, I did have the latest version of it (4323000 as of writing) and I did set this as a module dependency to my main module (using Android Studio here). But that little line above fixed everything.

You need to install the entire ruby and not just the minimum package. The correct command to use is:

sudo apt install ruby-full

The following command will also not install a complete ruby:

sudo apt-get install ruby2.3-dev

You can use input text with "list" attribute, which refers to the datalist of values.

<input type="text" name="city" list="cityname">_x000D_
    <datalist id="cityname">_x000D_
      <option value="Boston">_x000D_
      <option value="Cambridge">_x000D_
    </datalist>

This creates a free text input field that also has a drop-down to select predefined choices. Attribution for example and more information: https://www.w3.org/wiki/HTML/Elements/datalist

It may be helpful to bind radio-button to styled label. Futher details in this answer.

If you are using HTML5 (and I guess nowadays everyone uses that), there is an attribute called download.

For example,

<a href="somepathto.pdf" download="filename">

Here filename is optional, but if provided, it will take this name for the downloaded file.

It probably aimed to select all the informations in your table. If you use this kind of query (for example in PHP) :

mysql_query("SELECT * FROM newsletter WHERE email = '$email'");

The email ' OR 1=1/* will give this kind of query :

mysql_query("SELECT * FROM newsletter WHERE email = '' OR 1=1/*");

So it selects all the rows (because 1=1 is always true and the rest of the query is 'commented'). But it was not successful

• if strings used in your queries are escaped
• if you don't display all the queries results on a page...

You can use the following code to check if a textbox object is null/empty

'Checks if the box is null

If Me.TextBox & "" <> "" Then

        'Enter Code here...

End if

http://jsfiddle.net/LRD5x/30/ A simple solution.

HTML

<form ng-submit="sendForm($event)" ng-class={submitted:submitted}>

JS

$scope.sendForm = function($event) {
  $event.preventDefault()
  $scope.submitted = true
};

CSS

.submitted input.ng-invalid:not(:focus) {
    background-color: #FA787E;
}

input.ng-invalid ~ .alert{
    display:none;
}
.submitted input.ng-invalid ~ .alert{
    display:block;
}

You can submit the form without refreshing the page, but to my knowledge it is impossible without using a JavaScript/Ajax call to a PHP script on your server. The following example uses the jQuery JavaScript library.

HTML

<form method = 'post' action = '' id = 'theForm'>
...
</form>

JavaScript

$(function() {
    $("#theForm").submit(function() {
        var data = "a=5&b=6&c=7";
        $.ajax({
            url: "path/to/php/file.php",
            data: data,
            success: function(html) {
                .. anything you want to do upon success here ..
                alert(html); // alert the output from the PHP Script
            }
        });
        return false;
    });
});

Upon submission, the anonymous Javascript function will be called, which simply sends a request to your PHP file (which will need to be in a separate file, btw). The data above needs to be a URL-encoded query string that you want to send to the PHP file (basically all of the current values of the form fields). These will appear to your server-side PHP script in the $_GET super global. An example is below.

var data = "a=5&b=6&c=7";

If that is your data string, then the PHP script will see this as:

echo($_GET['a']); // 5
echo($_GET['b']); // 6
echo($_GET['c']); // 7

You, however, will need to construct the data from the form fields as they exist for your form, such as:

var data = "user=" + $("#user").val();

(You will need to tag each form field with an 'id', the above id is 'user'.)

After the PHP script runs, the success function is called, and any and all output produced by the PHP script will be stored in the variable html.

...
success: function(html) {
    alert(html);
}
...

Another way without JavaScript is to use <form autocomplete="off"> to prevent the browser from re-filling the form with the last values.

You can do it using the foreach loop

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

  foreach(DataRow row in dr_art_line_2.Rows)
  {
     QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
  }

I believe TLSV1_ALERT_PROTOCOL_VERSION is alerting you that the server doesn't want to talk TLS v1.0 to you. Try to specify TLS v1.2 only by sticking in these lines:

import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)

# Create HTTPS connection
c = HTTPSConnection("0.0.0.0", context=context)

Note, you may need sufficiently new versions of Python (2.7.9+ perhaps?) and possibly OpenSSL (I have "OpenSSL 1.0.2k 26 Jan 2017" and the above seems to work, YMMV)

request.getSession(true) and request.getSession() both do the same thing, but if we use request.getSession(false) it will return null if session object not created yet.

This is still not fixed in Xcode Version 8.0 beta 2 (8S162m) for me and extra logs are also appearing in the Xcode console

** EDIT 8/1/16: This has been acknowledged in the release notes for Xcode 8 Beta 4 (8S188o) as an issues still persisting.

Known Issues in Xcode 8 beta 4 – IDE

Debugging

• Xcode Debug Console shows extra logging from system frameworks when debugging applications in the Simulator. (27331147, 26652255)

Presumably this will be resolved by the GM release. Until then patience and although not ideal but a workaround I'm using is below...

Similar to the previous answer I am having to:

• prefix my print logs with some kind of special character (eg * or ^ or ! etc etc)

• Then use the search box on the bottom right of the console pane to filter my console logs by inputing my chosen special character to get the console to display my print logs as intended

There is a jquery print area. I've been using it for some time now.

$(".printMe").click(function(){
   $("#outprint").printArea({ mode: 'popup', popClose: true });
});

Use the equals method. Why are you so worried that it's expensive?

We can create a [debounce] directive which overwrites ngModel's default viewToModelUpdate function with an empty one.

Directive Code

@Directive({ selector: '[debounce]' })
export class MyDebounce implements OnInit {
    @Input() delay: number = 300;

    constructor(private elementRef: ElementRef, private model: NgModel) {
    }

    ngOnInit(): void {
        const eventStream = Observable.fromEvent(this.elementRef.nativeElement, 'keyup')
            .map(() => {
                return this.model.value;
            })
            .debounceTime(this.delay);

        this.model.viewToModelUpdate = () => {};

        eventStream.subscribe(input => {
            this.model.viewModel = input;
            this.model.update.emit(input);
        });
    }
}

How to use it

<div class="ui input">
  <input debounce [delay]=500 [(ngModel)]="myData" type="text">
</div>

To add to the above answers, there's a good article: Useful JVM Flags – Part 8 (GC Logging) by Patrick Peschlow.

A brief excerpt:

The flag -XX:+PrintGC (or the alias -verbose:gc) activates the “simple” GC logging mode

By default the GC log is written to stdout. With -Xloggc:<file> we may instead specify an output file. Note that this flag implicitly sets -XX:+PrintGC and -XX:+PrintGCTimeStamps as well.

If we use -XX:+PrintGCDetails instead of -XX:+PrintGC, we activate the “detailed” GC logging mode which differs depending on the GC algorithm used.

With -XX:+PrintGCTimeStamps a timestamp reflecting the real time passed in seconds since JVM start is added to every line.

If we specify -XX:+PrintGCDateStamps each line starts with the absolute date and time.

For many of the sites I build the client will ask for a 100vh banner and just as you have found, it results in a bad "jumpy" experience on mobile when you begin to scroll. This is how I solve the problem for a smooth consistent experience across all devices:

I first set my banner element CSS to height:100vh

Then I use jQuery to get the height in pixels of my banner element and apply an inline style using this height.

var viewportHeight = $('.banner').outerHeight();
$('.banner').css({ height: viewportHeight });

Doing this solves the issue on mobile devices as when the page loads, the banner element is set to 100vh using CSS and then jQuery overrides this by putting inline CSS on my banner element which stops it from resizing when a user begins to scroll.

However, on desktop if a user resizes their browser window my banner element won't resize because it now has a fixed height set in pixels due to the above jQuery. To address this I use Mobile Detect to add a 'mobile' class to the body of my document. And then I wrap the above jQuery in an if statement:

if ($('body').hasClass('mobile')) {
  var viewportHeight = $('.banner').outerHeight();
  $('.banner').css({ height: viewportHeight });
}

As a result, if a user is on a mobile device the class 'mobile' is present on the body of my page and the above jQuery is executed. So my banner element will only get the inline CSS applied on mobile devices meanwhile on desktop the original 100vh CSS rule remains in place.

I assume you know how to get the DOM object for the <a> element (use document.getElementById or some other method).

To add any attribute, just use the setAttribute method on the DOM object:

a = document.getElementById(...);
a.setAttribute("href", "somelink url");

$str = preg_replace('/[\s]+/', ' ', $str);

I just ran into this. I'm on Ubuntu 20.04. What worked? Reinstalling Docker:

sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo apt-get install docker-ce docker-ce-cli containerd.io

A bit crude, I know. I tried pruning Docker, but it still would not work.

I fixed this issue on Windows 10 by uninstalling node from Add or remove programs -> Node.js

Then I installed version 11.15.0 from https://nodejs.org/download/release/v11.15.0/

Choose node-v11.15.0-x64.msi if your running windows 64bit.

You can fix this by passing parameters rather than relying on Globals

def function(Var1, Var2): 
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    return Var1 - 1
function(1, 1)

Microsoft has also implemented the operators '<' and '>'. So you use these to compare two dates.

if (date1 < DateTime.Now)
   Console.WriteLine("Less than the current time!");

Please be more specific! What do you mean by "it doesn't work"? Post the exact output (or error message), your OS and awk version:

% awk -F\| '{
  for (i = 0; ++i <= NF;)
    print i, $i
  }' <<<'12|23|11'
1 12
2 23
3 11

Or, using split:

% awk '{
  n = split($0, t, "|")
  for (i = 0; ++i <= n;)
    print i, t[i]
  }' <<<'12|23|11'
1 12
2 23
3 11

Edit: on Solaris you'll need to use the POSIX awk (/usr/xpg4/bin/awk) in order to process 4000 fields correctly.

HTML:

<div id="log"></div>

JS:

document.getElementById("log").innerHTML="WHATEVER YOU WANT...";

Use the RIGHT function... e.g.

DECLARE @testnum TINYINT
SET @testnum = 3
PRINT RIGHT('00' + CONVERT(VARCHAR(2), @testnum), 2)

Try to call object like this:

(<any>Object).dosomething

This error has come because you have declared them as optional using ?. Now Typescript does strict check and it won't allow doing anything that may be undefined. Therefore, you can use (<any>yourObject) here.

I ran into the same issue and it's even worse: I needed both "import" and "require"

1. Some newer ES6 modules works only with import.
2. Some CommonJS works with require.

Here is what worked for me:

1. Turn your js file into .mjs as suggested in other answers

2. "require" is not defined with ES6 module, so you can define it this way:

   import { createRequire } from 'module'
   const require = createRequire(import.meta.url);
   

   Now 'require' can be used in the usual way.

3. Use import for ES6 modules and require for commonJS.

Some useful links: node.js's own documentation. difference between import and require. Mozilla has some nice documentation about import

My favorite visual merge tool is SourceGear DiffMerge

• It is free.
• Cross-platform (Windows, OS X, and Linux).
• Clean visual UI
• All diff features you'd expect (Diff, Merge, Folder Diff).
• Command line interface.
• Usable keyboard shortcuts.

<html>
    <head>
        <title>Page</title>
    </head>
    <body>
       <a href="./">Folder directory</a>

I use an extension method:

public static class AttributesHelperExtension
    {
        public static string ToDescription(this Enum value)
        {
            var da = (DescriptionAttribute[])(value.GetType().GetField(value.ToString())).GetCustomAttributes(typeof(DescriptionAttribute), false);
            return da.Length > 0 ? da[0].Description : value.ToString();
        }
}

Now decorate the enum with:

public enum AuthenticationMethod
{
    [Description("FORMS")]
    FORMS = 1,
    [Description("WINDOWSAUTHENTICATION")]
    WINDOWSAUTHENTICATION = 2,
    [Description("SINGLESIGNON ")]
    SINGLESIGNON = 3
}

When you call

AuthenticationMethod.FORMS.ToDescription() you will get "FORMS".

Have you used the variable sum anywhere else? That would explain it.

>>> sum = 1
>>> numbers = [1, 2, 3]
>>> numsum = (sum(numbers))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

The name sum doesn't point to the function anymore now, it points to an integer.

Solution: Don't call your variable sum, call it total or something similar.

Ok, solved my problem, if anyone is passing by here is the answer:

Just had to add left: 0, and top: 0, to the styles, and yes, I'm tired.

position: 'absolute',
left:     0,
top:      0,

This example from the angular documentation site just does href without even assigning it to an empty string:

[<a href ng-click="colors.splice($index, 1)">X</a>]

You may use scanf for this purpose with a little trick. Actually, you should allow user input until user hits Enter (\n). This will consider every character, including space. Here is example:

int main()
{
  char string[100], c;
  int i;
  printf("Enter the string: ");
  scanf("%s", string);
  i = strlen(string);      // length of user input till first space
  do
  {
    scanf("%c", &c);
    string[i++] = c;       // reading characters after first space (including it)
  } while (c != '\n');     // until user hits Enter
  string[i - 1] = 0;       // string terminating
return 0;
}

How this works? When user inputs characters from standard input, they will be stored in string variable until first blank space. After that, rest of entry will remain in input stream, and wait for next scanf. Next, we have a for loop that takes char by char from input stream (till \n) and apends them to end of string variable, thus forming a complete string same as user input from keyboard.

Hope this will help someone!

Well to obtain all different values in a Dataframe you can use distinct. As you can see in the documentation that method returns another DataFrame. After that you can create a UDF in order to transform each record.

For example:

val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")

// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)

// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))

My answer is tested on Windows 7 with installation of NetBeans IDE 6.9.1 which has bundled Tomcat version 6.0.26. The instruction may work with other tomcat versions according to my opinion.

If you are starting the Apache Tomcat server from the Servers panel in NetBeans IDE then you shall know that the Catalina base and config files used by NetBeans IDE to start the Tomcat server are kept at a different location.

Steps to know the catalina base directory for your installation:

1. Right click on the Apache Tomcat node in Servers panel and choose properties option in the context menu. This will open a dialog box named Servers.
2. Check the directory name of the field Catalina Base, this is that directory where the current conf/tomcat-users.xml is located and which you want to open and read.
   (In my case it is C:\Users\Tushar Joshi\.netbeans\6.9\apache-tomcat-6.0.26_base )
3. Open this directory in My Computer and go to the conf directory where you will find the actual tomcat-users.xml file used by NetBeans IDE. NetBeans IDE comes configured with one default password with username="ide" and some random password, you may change this username and password if you want or use it for your login also
4. This dialog box also have username and password field which are populated with these default username and password and NetBeans IDE also offers you to open the manager application by right clicking on the manager node under the Apache Tomcat node in Servers panel
5. The only problem with the NetBeans IDE is it tries to open the URL http://localhost:8084/manager/ which shall be http://localhost:8084/manager/html now

In Android the visual design is stored in XML files and each Activity is associated to a design.

setContentView(R.layout.main)

R means Resource

layout means design

main is the xml you have created under res->layout->main.xml

Whenever you want to change the current look of an Activity or when you move from one Activity to another, the new Activity must have a design to show. We call setContentView in onCreate with the desired design as argument.

I was facing same issue then I read first few lines of this question and I realised that I was trying to run command at the root directory of my bash profile instead of CD/my work project folder. I switched back to my work folder and able to clone the project successfully

Using the Window.URL API - https://developer.mozilla.org/en-US/docs/Web/API/Window/URL

Works with http(s), ports etc.

var url = new URL('/path/to/websocket', window.location.href);

url.protocol = url.protocol.replace('http', 'ws');

url.href // => ws://www.example.com:9999/path/to/websocket

Certain MySQL engines support foreign keys. For example, InnoDB can establish constraints based on foreign keys. If you try to delete an entry in one table that has dependents in another, the delete will fail.

If you are using a table type in MySQL, such as MyISAM, that doesn't support foreign keys, you don't link the tables anywhere except your diagrams and queries.

For example, in a query you link two tables in a select statement with a join:

SELECT a, b from table1 LEFT JOIN table2 USING (common_field);

Well, in my case I had to test a Phone Number with the help of regex, and I was getting the same error,

Invalid regular expression: /+923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/: Nothing to repeat'

So, what was the error in my case was that + operator after the / in the start of the regex. So enclosing the + operator with square brackets [+], and again sending the request, worked like a charm.

Following will work:

/[+]923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/

This answer may be helpful for those, who got the same type of error, but their chances of getting the error from this point of view, as mine! Cheers :)

First of all There is no such class called Static class.The Static modifier use with inner class (called as Nested Class) says that it is a static member of Outer Class which means we can access it as with other static members and without having any instance of Outer class. (Which is benefit of static originally.)

Difference between using Nested class and regular Inner class is:

OuterClass.InnerClass inner = new OuterClass().new InnerClass();

First We can to instantiate Outerclass then we Can access Inner.

But if Class is Nested then syntax is:

OuterClass.InnerClass inner = new OuterClass.InnerClass();

Which uses the static Syntax as normal implementation of static keyword.

There is another place where the TNS location is stored: If you're using Windows, open regedit and navigate to My HKEY Local Machine/Software/ORACLE/KEY_OraClient10_home1 where KEY_OraClient10_home1 is your Oracle home. If there is a string entry called TNS_ADMIN, then the value of that entry will point to the TNS file that Oracle is using on your computer.

// offsetWidth includes width of scroll bar and clientWidth doesn't. As rule, it equals 14-18px. so:

 var scrollBarWidth = element.offsetWidth - element.clientWidth;

you need to execute two queries:

One - to add the default value to the column required

ALTER TABLE 'Table_Name` ADD DEFAULT 'value' FOR 'Column_Name'

i want add default value to Column IsDeleted as below:

Example: ALTER TABLE [dbo].[Employees] ADD Default 0 for IsDeleted

Two - to alter the column value nullable to not null

ALTER TABLE 'table_name' ALTER COLUMN 'column_name' 'data_type' NOT NULL

i want to make the column IsDeleted as not null

ALTER TABLE [dbo].[Employees] Alter Column IsDeleted BIT NOT NULL

Unlike object oriented languages such as Smalltalk or Python, where the constructor is a virtual method of the object representing the class (which means you don't need the GoF abstract factory pattern, as you can pass the object representing the class around instead of making your own), C++ is a class based language, and does not have objects representing any of the language's constructs. The class does not exist as an object at runtime, so you can't call a virtual method on it.

This fits with the 'you don't pay for what you don't use' philosophy, though every large C++ project I've seen has ended up implementing some form of abstract factory or reflection.

Yes - different

chmod a+x will add the exec bits to the file but will not touch other bits. For example file might be still unreadable to others and group.

chmod 755 will always make the file with perms 755 no matter what initial permissions were.

This may or may not matter for your script.

Streams Java 8

Along with forEach method that accepts a lambda expression we have also got stream APIs, in Java 8.

Iterate over entries (Using forEach and Streams):

sample.forEach((k,v) -> System.out.println(k + "=" + v)); 
sample.entrySet().stream().forEachOrdered((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });
sample.entrySet().parallelStream().forEach((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });

The advantage with streams is they can be parallelized easily and can be useful when we have multiple CPUs at disposal. We simply need to use parallelStream() in place of stream() above. With parallel streams it makes more sense to use forEach as forEachOrdered would make no difference in performance. If we want to iterate over keys we can use sample.keySet() and for values sample.values().

Why forEachOrdered and not forEach with streams ?

Streams also provide forEach method but the behaviour of forEach is explicitly nondeterministic where as the forEachOrdered performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach does not guarantee that the order would be kept. Also check this for more.

I had this issue with a weird behavior: clearing the browser cache didn't fix it but clearing the cookies (that is, the PHP session ID cookie) did solve the issue.

This has to be done after you have checked all other answers, including verifying you do have the token in a hidden form input field.

You can always tell the window to start in maximized... it should give you the same result... Like this: this.WindowState = FormWindowState.Maximized;

P.S. You could also try (and I'm not recommending this) to subtract the taskbar height.

The exact value is sizeof(a).
You might also take a risk and assume that it is in this case no less than 2 and no greater than 16.

Try shutil.rmtree:

import shutil
shutil.rmtree('/path/to/your/dir/')

I tried all of the above said solutions but did not worked out for me, Here is what i did to get it done project-> config build path-> order and export-> move dependent project on top

As alternative, you can code something like this:

    <Border 
            x:Name="borderBtnAdd"
            BorderThickness="1" 
            BorderBrush="DarkGray" 
            CornerRadius="360" 
            Height="30" 
            Margin="0,10,10,0" 
            VerticalAlignment="Top" HorizontalAlignment="Right" Width="30">
        <Image x:Name="btnAdd"
               Source="Recursos/Images/ic_add_circle_outline_black_24dp_2x.png"
               Width="{Binding borderBtnAdd.Width}" Height="{Binding borderBtnAdd.Height}"/>
    </Border>

The "Button" will look something like this:

You could set any other content instead of the image.

I just wanted to append to Imanou Petit's answer #2. To ensure margins are exact regardless of screen width, I use an iterative solver with a desired margin, and the # of columns as inputs. I also added a directional flag on where their final margins will be compared to their target.

The iterative solver is shown below and returns cellWidth and margin.

private func iterativeCellSpacing(targetMargins : CGFloat,
                                  cellsPerRow : Int,
                                  isMinTarget : Bool) -> (CGFloat, CGFloat)
{
    var w : CGFloat = 0
    var m : CGFloat = targetMargins
    let cols : CGFloat = CGFloat(cellsPerRow)

    let numMargins : CGFloat = cols + 1.0
    let screenWidth : CGFloat = collectionView!.bounds.size.width


    var delta = CGFloat.greatestFiniteMagnitude
    while abs(delta) > 0.001
    {
        let totalMarginSpacing = numMargins * m
        let totalCellSpacing = screenWidth - totalMarginSpacing

        if (isMinTarget)
        {
            w = floor(totalCellSpacing / cols)
            m = ceil((screenWidth - cols * w) / numMargins)
        }
        else
        {
            w = ceil(totalCellSpacing / cols)
            m = floor((screenWidth - cols * w) / numMargins)
        }

        delta = screenWidth - w * CGFloat(cellsPerRow) - m * numMargins
    }

    return (w, m)
}

I call it as such:

fileprivate var margin: CGFloat = 20
fileprivate var cellWidth : CGFloat = 80
fileprivate let cellsPerRow = 4

override func viewDidLoad()
{
    super.viewDidLoad()

    (cellWidth, margin) = iterativeCellSpacing(targetMargins: margin, cellsPerRow: 4, isMinTarget: true)
    ...
}

I then apply the cellWidth and margin values to the flow layout as such:

extension MyCollectionController : UICollectionViewDelegateFlowLayout

{ func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { return CGSize(width: cellWidth, height: cellWidth) }

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    collectionView?.collectionViewLayout.invalidateLayout()
    super.viewWillTransition(to: size, with: coordinator)
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets
{
    return UIEdgeInsetsMake(margin, margin, margin, margin)
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat
{
    return margin
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat
{
    return margin
}

}

Hope this helps. There probably is an easier way to ensure margins are exact, but this is one method. Also, this code hasn't been tested for devices that allow rotating collectionviews.

Thanks,

you can use sort() , limit() ,skip() to get last N record start from any skipped value

db.collections.find().sort(key:value).limit(int value).skip(some int value);

Python comes with numerous ways of formatting strings:

New style .format(), which supports a rich formatting mini-language:

>>> temperature = 10
>>> print("the furnace is now {} degrees!".format(temperature))
the furnace is now 10 degrees!

Old style % format specifier:

>>> print("the furnace is now %d degrees!" % temperature)
the furnace is now 10 degrees!

In Py 3.6 using the new f"" format strings:

>>> print(f"the furnace is now {temperature} degrees!")
the furnace is now 10 degrees!

Or using print()s default separator:

>>> print("the furnace is now", temperature, "degrees!")
the furnace is now 10 degrees!

And least effectively, construct a new string by casting it to a str() and concatenating:

>>> print("the furnace is now " + str(temperature) + " degrees!")
the furnace is now 10 degrees!

Or join()ing it:

>>> print(' '.join(["the furnace is now", str(temperature), "degrees!"]))
the furnace is now 10 degrees!

public static class HelperExtensions
{
    //Convert Image to byte[] array:
    public static byte[] ToByteArray(this Image imageIn)
    {
        var ms = new MemoryStream();
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
        return ms.ToArray();
    }

    //Convert byte[] array to Image:

        var ms = new MemoryStream(byteArrayIn);
        var returnImage = Image.FromStream(ms);

You should convert the string to an enumeration value before comparing.

Enum.TryParse("Retailer", out AccountType accountType);

Then

if (userProfile?.AccountType == accountType)
{
    //your code
}

You can use pgrep with -f (full command line) and -l (long description):

pgrep -l -f PatternOfProcess

This method has a crucial difference with any of the other responses: it works on CygWin, so you can use it to obtain the full command line of any process running under Windows (execute as elevated if you want data about any elevated/admin process). Any other method for doing this on Windows is more awkward ( for example ).
Furthermore: in my tests, the pgrep way has been the only system that worked to obtain the full path for scripts running inside CygWin's python.

I've been using this module ng2 truncate, its pretty easy, import module and u are ready to go... in {{ data.title | truncate : 20 }}

Yes it's possible. Follow these steps:

1. Download Xcode 10.2 via this link (you need to be signed in with your Apple Id): https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_10.2/Xcode_10.2.xip and install it
2. Edit Xcode.app/Contents/Info.plist and change the Minimum System Version to 10.13.6
3. Do the same for Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/Info.plist (might require a restart of Xcode and/or Mac OS to make it open the simulator on run)
4. Replace Xcode.app/Contents/Developer/usr/bin/xcodebuild with the one from 10.1 (or another version you have currently installed, such as 10.0).
5. If there are problems with the simulator, reboot your Mac

In this case, as you want to change the src of the first value of your element, you have no need to build up a function. You can change this right in the element:

<a href='#' onclick='this.firstChild.src="../template/save.png"')'>
  <img src="../template/edit.png" id="edit-save"/>
</a>

You have several ways to do this. You can also create a function to automatize the process:

function changeSrc(p, t) { /* where p: Parent, t: ToSource */
  p.firstChild.src = t
}

Then you can:

<a href='#' onclick='changeSrc(this, "../template/save.png");'>
  <img src="../template/edit.png" id="edit-save"/>
</a>

Duplicate question which basically says use ExecuteScalar() instead.

I think you can create empty numpy array like:

>>> import numpy as np
>>> empty_array= np.zeros(0)
>>> empty_array
array([], dtype=float64)
>>> empty_array.shape
(0,)

This format is useful when you want to append numpy array in the loop.

Run this

    for (Method m : sex.class.getDeclaredMethods()) {
        System.out.println(m);
    }

you will see

public static test.Sex test.Sex.valueOf(java.lang.String)
public static test.Sex[] test.Sex.values()

These are all public methods that "sex" class has. They are not in the source code, javac.exe added them

Notes:

1. never use sex as a class name, it's difficult to read your code, we use Sex in Java

2. when facing a Java puzzle like this one, I recommend to use a bytecode decompiler tool (I use Andrey Loskutov's bytecode outline Eclispe plugin). This will show all what's inside a class

Active Directory does not store the group membership on user objects. It only stores the Member list on the group. The tools show the group membership on user objects by doing queries for it.

How about:

(&(objectClass=group)(member=cn=my,ou=full,dc=domain))

(You forgot the (& ) bit in your example in the question as well).

Might be already answered, but you can try this simple program to determine if and what installation of boost you have :

#include<boost/version.hpp>
#include<iostream>
using namespace std;
int main()
{
cout<<BOOST_VERSION<<endl;
return 0;
}

I was able to fix this issue by changing $(document).ready() to window.onLoad().

1. First you have to run the mongod command in your terminal. Make sure the command executes properly.

2. Then in a new terminal tab run the mongo command.

3. Then open the Robomongo GUI and create a new connection with the default settings.

If you want to find ALL controls of a specific type, you might be interested in this snippet too

    public static IEnumerable<T> FindVisualChildren<T>(DependencyObject parent) 
        where T : DependencyObject
    {
        int childrenCount = VisualTreeHelper.GetChildrenCount(parent);
        for (int i = 0; i < childrenCount; i++)
        {
            var child = VisualTreeHelper.GetChild(parent, i);

            var childType = child as T;
            if (childType != null)
            {
                yield return (T)child;
            }

            foreach (var other in FindVisualChildren<T>(child))
            {

"Stack Me 123 Heppa1 oeu".toCharArray() ?

I had to get rid of the NULL values before using the command recommended by Andy above. An example:

df = pd.DataFrame(index = [0, 1, 2], columns=['first', 'second', 'third'])
df.ix[:, 'first'] = 'myword'
df.ix[0, 'second'] = 'myword'
df.ix[2, 'second'] = 'myword'
df.ix[1, 'third'] = 'myword'
df

    first   second  third
0   myword  myword   NaN
1   myword  NaN      myword 
2   myword  myword   NaN

Now running the command:

~df["second"].str.contains(word)

I get the following error:

TypeError: bad operand type for unary ~: 'float'

I got rid of the NULL values using dropna() or fillna() first and retried the command with no problem.

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

This is cheating, and not even remotely simple, but I once wrote a shoot'em up in 20 lines of C++, using the Allegro graphics library. No real criteria for what a line was, but it was a bit ago, and it was made purely for fun. It even had crude sound effects.

Here's what it looked like:

And here's the code (should compile):

After installing Postgresql I did the below steps.

1. open the file pg_hba.conf for Ubuntu it will be in /etc/postgresql/9.x/main and change this line:

   local   all             postgres                                peer

   to

   local   all             postgres                                trust

2. Restart the server

   $ sudo service postgresql restart
   

3. Login into psql and set your password

   $ psql -U postgres
   db> ALTER USER postgres with password 'your-pass';
   

4. Finally change the pg_hba.conf from

   local   all             postgres                                trust

   to

   local   all             postgres                                md5

After restarting the postgresql server, you can access it with your own password

Authentication methods details:

trust - anyone who can connect to the server is authorized to access the database

peer - use client's operating system user name as database user name to access it.

md5 - password-base authentication

for further reference check here

With Apache Commons IO you can do this in one line.

IOUtils.toString(request.getReader())

I'm not an expert, but I did a lot of looking to implement this for myself. I found something different, but modified it to accomplish this. It's really quite simple:

The function takes two arguments, a div containing only the words "show more" [or whatever] and a div containing the originally hidden text and the words "show less." The function displays the one div and hides the other.

NOTE: If more than one show/hide on page, assign different ids to divs Colors can be changed

<p>Here is text that is originally displayed</p>

<div id="div1">
<p style="color:red;" onclick="showFunction('div2','div1')">show more</p></div>
<div id="div2" style="display:none">

<p>Put expanded text here</p>

<p style="color:red;" onclick="showFunction('div1','div2')">show less</p></div>

<p>more text</p>

Here is the Script:

<script>
function showFunction(diva, divb) {
    var x = document.getElementById(diva);
    var y = document.getElementById(divb);
          x.style.display = 'block';
          y.style.display = 'none';
}
</script>

I think this is non-restful. I do not think the restful service should handle the requirement of forcing the user to confirm a delete. I would handle this in the UI.

Does specifying force_delete=true make sense if this were a program's API? If someone was writing a script to delete this resource, would you want to force them to specify force_delete=true to actually delete the resource?

The character '\' is a special character and needs to be escaped when used as part of a String, e.g., "\". Here is an example of a string comparison using the '\' character:

if (invName.substring(j,k).equals("\\")) {...}

You can also perform direct character comparisons using logic similar to the following:

if (invName.charAt(j) == '\\') {...}

1. If you want to integrate Retrofit (all steps defined here):

Goto my blog : retrofit with kotlin

2. Please use android-async-http library.

the link below explains everything step by step.

http://loopj.com/android-async-http/

Here are sample apps:

1. http://www.techrepublic.com/blog/software-engineer/calling-restful-services-from-your-android-app/

2. http://blog.strikeiron.com/bid/73189/Integrate-a-REST-API-into-Android-Application-in-less-than-15-minutes

Create a class :

public class HttpUtils {
  private static final String BASE_URL = "http://api.twitter.com/1/";
 
  private static AsyncHttpClient client = new AsyncHttpClient();

  public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(getAbsoluteUrl(url), params, responseHandler);
  }

  public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(getAbsoluteUrl(url), params, responseHandler);
  }
      
  public static void getByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(url, params, responseHandler);
  }

  public static void postByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(url, params, responseHandler);
  }

  private static String getAbsoluteUrl(String relativeUrl) {
      return BASE_URL + relativeUrl;
  }
}

Call Method :

    RequestParams rp = new RequestParams();
    rp.add("username", "aaa"); rp.add("password", "aaa@123");
                    
    HttpUtils.post(AppConstant.URL_FEED, rp, new JsonHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
            // If the response is JSONObject instead of expected JSONArray
            Log.d("asd", "---------------- this is response : " + response);
            try {
                JSONObject serverResp = new JSONObject(response.toString());                                                
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }                   
        }
            
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) {
            // Pull out the first event on the public timeline
                    
        }
    });

Please grant internet permission in your manifest file.

 <uses-permission android:name="android.permission.INTERNET" />

you can add compile 'com.loopj.android:android-async-http:1.4.9' for Header[] and compile 'org.json:json:20160212' for JSONObject in build.gradle file if required.

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

I do not like use pure "a" tag, too much typing. So I come with solution. In view it look

<%: Html.ActionLink(node.Name, "Show", "Browse", 
                    Dic.Route("id", node.Id), Dic.New("data-nodeId", node.Id)) %>

Implementation of Dic class

public static class Dic
{
    public static Dictionary<string, object> New(params object[] attrs)
    {
        var res = new Dictionary<string, object>();
        for (var i = 0; i < attrs.Length; i = i + 2)
            res.Add(attrs[i].ToString(), attrs[i + 1]);
        return res;
    }

    public static RouteValueDictionary Route(params object[] attrs)
    {
        return new RouteValueDictionary(Dic.New(attrs));
    }
}

Don't put a name for target window when you use window.open("","NAME",....)

If you do it you can only open it once. Use _blank, etc instead of.

As mentioned if-else would be better in this case, where you will be handling a range:

if(number >= 1 && number <= 4)
{
   //do something;
}
else if(number >= 5 && number <= 9)
{
   //do something else;
}

in my case i did following

$mail = new PHPMailer;
$mail->isSMTP();            
$mail->Host = '<YOUR HOST>';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = '<USERNAME>';
$mail->Password = '<PASSWORD>';
$mail->SMTPSecure = '';
$mail->smtpConnect([
    'ssl' => [
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    ]
]);
$mail->smtpClose();

$mail->From = '<[email protected]>';
$mail->FromName = '<MAIL FROM NAME>';

$mail->addAddress("<[email protected]>", '<SEND TO>');

$mail->isHTML(true);
$mail->Subject= '<SUBJECTHERE>';
$mail->Body =  '<h2>Test Mail</h2>';
$isSend = $mail->send();

Did you try using the SDK version 8. Since the device is in 2.2, and your SDK is at 10, there might be conflict.

Best of luck with ur downgrading efforts!! Hope this solves.

Here is a simple programe to capture a image from using laptop default camera.I hope that this will be very easy method for all.

import cv2

# 1.creating a video object
video = cv2.VideoCapture(0) 
# 2. Variable
a = 0
# 3. While loop
while True:
    a = a + 1
    # 4.Create a frame object
    check, frame = video.read()
    # Converting to grayscale
    #gray = cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)
    # 5.show the frame!
    cv2.imshow("Capturing",frame)
    # 6.for playing 
    key = cv2.waitKey(1)
    if key == ord('q'):
        break
# 7. image saving
showPic = cv2.imwrite("filename.jpg",frame)
print(showPic)
# 8. shutdown the camera
video.release()
cv2.destroyAllWindows 

You can see my github code here

Most likely, an error occurred when the daemon attempted to cleanup the container, and he is now stuck in this "zombie" state.

I'm afraid your only option here is to manually clean it up:

$ sudo rm -rf /var/lib/docker/<storage_driver>/11667ef16239.../

Where <storage_driver> is the name of your driver (aufs, overlay, btrfs, or devicemapper).

You can remove the warning by adding the below code in <intent-filter> inside <activity>

<action android:name="android.intent.action.VIEW" />

Another function that would help you look at missing data would be df_status from funModeling library

library(funModeling)

iris.2 is the iris dataset with some added NAs.You can replace this with your dataset.

df_status(iris.2)

This will give you the number and percentage of NAs in each column.

Yes, you can use jQuery's attribute selector for that.

var linksToGoogle = $('a[href="http://google.com"]');

Alternatively, if your interest is rather links starting with a certain URL, use the attribute-starts-with selector:

var allLinksToGoogle = $('a[href^="http://google.com"]');

The original code you suggest is the best way.

Matlab is extremely good at vectorized operations such as this, at least for large vectors.

The built-in norm function is very fast. Here are some timing results:

V = rand(10000000,1);
% Run once
tic; V1=V/norm(V); toc           % result:  0.228273s
tic; V2=V/sqrt(sum(V.*V)); toc   % result:  0.325161s
tic; V1=V/norm(V); toc           % result:  0.218892s

V1 is calculated a second time here just to make sure there are no important cache penalties on the first call.

Timing information here was produced with R2008a x64 on Windows.

EDIT:

Revised answer based on gnovice's suggestions (see comments). Matrix math (barely) wins:

clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V);         end; toc % 6.3 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 9.3 s
tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 6.2 s ***
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 9.2 s
tic; for i=1:N, V1=V/norm(V);           end; toc % 6.4 s

IMHO, the difference between "norm(V)" and "sqrt(V'*V)" is small enough that for most programs, it's best to go with the one that's more clear. To me, "norm(V)" is clearer and easier to read, but "sqrt(V'*V)" is still idiomatic in Matlab.

Try this simple solution to convert file to base64 string

String base64String = imageFileToByte(file);

public String imageFileToByte(File file){

    Bitmap bm = BitmapFactory.decodeFile(file.getAbsolutePath());
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
    byte[] b = baos.toByteArray();
    return Base64.encodeToString(b, Base64.DEFAULT);
}

In addition from the command prompt run SET.

This displayed the "LOGONSERVER" value which indicates the specific domain controller you are using (there can be more than one).

Then you got to that server's NetBios Share \Servername\SYSVOL\domain.local\scripts.

You seem to be specifying the form to use a HTTP 'GET' request using FormMethod.Get. This will not work unless you tell it to do a post as that is what you seem to want the ActionResult to do. This will probably work by changing FormMethod.Get to FormMethod.Post.

As well as this you may also want to think about how Get and Post requests work and how these interact with the Model.

Please follow the below steps :

 1) Locate php.ini in your apache bin folder, I.e Apache/bin/php.ini
 2) Remove the ; from the beginning of extension=php_soap.dll
 3) Restart your Apache server (by using : 
    # /etc/init.d/apache2 restart OR 
    $ sudo /etc/init.d/apache2 restart OR 
    $ sudo service apache2 restart)
 4) Look up your phpinfo();

 you may check here as well,if this does not solve your issue:

The other answers are quite good, but it would also be useful to add LIMIT 1 (or the equivalent, to prevent the checking of unnecessary rows.

Using ES6 syntax does not work in node, unfortunately, you have to have babel apparently to make the compiler understand syntax such as export or import.

npm install babel-cli --save

Now we need to create a .babelrc file, in the babelrc file, we’ll set babel to use the es2015 preset we installed as its preset when compiling to ES5.

At the root of our app, we’ll create a .babelrc file. $ npm install babel-preset-es2015 --save

At the root of our app, we’ll create a .babelrc file.

Hope it works ... :)

The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:

SELECT *
FROM server1table
    INNER JOIN server2.database.dbo.server2table ON .....

Did you check the string concatenation function? Something like:

update table_c set column_a = column_b || column_c 

should work. More here

<div *ngIf="currentStatus !== ('status1' || 'status2' || 'status3' || 'status4')">

You can use: interface{}..(type) as in this playground

package main
import "fmt"
func main(){
    types := []interface{} {"a",6,6.0,true}
    for _,v := range types{
        fmt.Printf("%T\n",v)
        switch v.(type) {
        case int:
           fmt.Printf("Twice %v is %v\n", v, v.(int) * 2)
        case string:
           fmt.Printf("%q is %v bytes long\n", v, len(v.(string)))
       default:
          fmt.Printf("I don't know about type %T!\n", v)
      }
    }
}

return $picName = time().'.'.$request->file->extension();

The time() function will make the image unique then the .$request->file->extension() gets the image extension for you.

You can use this it works well with Laravel 6 and above.

Note that adjacent whitespace will NOT be treated as a single delimiter, even when using String.Split(null). If any of your tokens are separated with multiple spaces or tabs, you'll get empty strings returned in your array.

From the documentation:

Each element of separator defines a separate delimiter character. If two delimiters are adjacent, or a delimiter is found at the beginning or end of this instance, the corresponding array element contains Empty.
