Try below piece of code.

this.dataGridView1.RefreshEdit();

Here's your code fixed up. Next forget bindingsource

 var select = "SELECT * FROM tblEmployee";
 var c = new SqlConnection(yourConnectionString); // Your Connection String here
 var dataAdapter = new SqlDataAdapter(select, c); 

 var commandBuilder = new SqlCommandBuilder(dataAdapter);
 var ds = new DataSet();
 dataAdapter.Fill(ds);
 dataGridView1.ReadOnly = true; 
 dataGridView1.DataSource = ds.Tables[0];

                           bitmap.GetHbitmap(),

From the STRTOTIME writeup Note:

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

It is as simple as that.

You're trying to call the isEmpty() method on a null reference (as List test = null; ). This will surely throw a NullPointerException. You should do if(test!=null) instead (Checking for null first).

The method isEmpty() returns true, if an ArrayList object contains no elements; false otherwise (for that the List must first be instantiated that is in your case is null).

Edit:

You may want to see this question.

You can do this:

sql = "Select * from ... your sql query here"
records_array = ActiveRecord::Base.connection.execute(sql)

records_array would then be the result of your sql query in an array which you can iterate through.

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

Try this

getExternalFilesDir(Environment.getDataDirectory().getAbsolutePath()).getAbsolutePath()

You should check the ADD and COPY documentation for a more detailed description of their behaviors, but in a nutshell, the major difference is that ADD can do more than COPY:

• ADD allows <src> to be a URL
• Referring to comments below, the ADD documentation states that:

If is a local tar archive in a recognized compression format (identity, gzip, bzip2 or xz) then it is unpacked as a directory. Resources from remote URLs are not decompressed.

Note that the Best practices for writing Dockerfiles suggests using COPY where the magic of ADD is not required. Otherwise, you (since you had to look up this answer) are likely to get surprised someday when you mean to copy keep_this_archive_intact.tar.gz into your container, but instead, you spray the contents onto your filesystem.

Without any example data, it really is difficult to know exactly what you are wanting. For instance, I can't at all divine what your object set (or is it sets) looks like.

That said, does the following help at all?

set1 <- data.frame(x = 4:6, y = 6:4, z = c(1, 3, 5))

plot(1:10, type="n")
XX <- "set1"
with(eval(as.symbol(XX)), symbols(x, y, circles = z, add=TRUE))

EDIT:

Now that I see your real task, here is a one-liner that'll do everything you want without requiring any for() loops:

with(dat, symbols(sq, cu, circles = num,
                  bg = c("red", "blue")[(num>5) + 1]))

The one bit of code that may feel odd is the bit specifying the background color. Try out these two lines to see how it works:

c(TRUE, FALSE) + 1
# [1] 2 1
c("red", "blue")[c(F, F, T, T) + 1]
# [1] "red"  "red"  "blue" "blue"

@vj9 thx. I update to xcode 7 . It show me the same error. Build well after set "NO"

set "NO" it works well.

List<T> already implements Collection<T> - why would you need to create a new one?

Collection<T> collection = myList;

The error message is absolutely right - you can't directly instantiate an interface. If you want to create a copy of the existing list, you could use something like:

Collection<T> collection = new ArrayList<T>(myList);

I had the same problem (changing a parameter from the HTTP request in the Filter). I ended up by using a ThreadLocal<String>. In the Filter I have:

class MyFilter extends Filter {
    public static final ThreadLocal<String> THREAD_VARIABLE = new ThreadLocal<>();
    public void doFilter(HttpServletRequest request, HttpServletResponse response, FilterChain chain) {
        THREAD_VARIABLE.set("myVariableValue");
        chain.doFilter(request, response);
    }
}

In my request processor (HttpServlet, JSF controller or any other HTTP request processor), I get the current thread value back:

...
String myVariable = MyFilter.THREAD_VARIABLE.get();
...

Advantages:

• more versatile than passing HTTP parameters (you can pass POJO objects)
• slightly faster (no need to parse the URL to extract the variable value)
• more elegant thant the HttpServletRequestWrapper boilerplate
• the variable scope is wider than just the HTTP request (the scope you have when doing request.setAttribute(String,Object), i.e. you can access the variable in other filtrers.

Disadvantages:

• You can use this method only when the thread which process the filter is the same as the one which process the HTTP request (this is the case in all Java-based servers I know). Consequently, this will not work when
  • doing a HTTP redirect (because the browser does a new HTTP request and there is no way to guarantee that it will be processed by the same thread)
  • processing data in separate threads, e.g. when using java.util.stream.Stream.parallel, java.util.concurrent.Future, java.lang.Thread.
• You must be able to modify the request processor/application

Some side notes:

• The server has a Thread pool to process the HTTP requests. Since this is pool:

  1. a Thread from this thread pool will process many HTTP requests, but only one at a time (so you need either to cleanup you variable after usage or to define it for each HTTP request = pay attention to code such as if (value!=null) { THREAD_VARIABLE.set(value);} because you will reuse the value from the previous HTTP request when value is null : side effects are guaranteed).
  2. There is no guarantee that two requests will be processed by the same thread (it may be the case but you have no guarantee). If you need to keep user data from one request to another request, it would be better to use HttpSession.setAttribute()
• The JEE @RequestScoped internally uses a ThreadLocal, but using the ThreadLocal is more versatile: you can use it in non JEE/CDI containers (e.g. in multithreaded JRE applications)

Use:

*.dll    #Exclude all dlls
!foo.dll #Except for foo.dll

From gitignore:

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

You can use += to concatenate strings, for example:

declare @test nvarchar(max)
set @test = ''
select @test += name from names

if you select @test, it will give you all names concatenated

If you're getting this error because you're purposefully trying to build to Java 6, but you have Java 7 elsewhere in Eclipse, then it may be because you are referencing a Java 7 tools.jar in a Java 6 environment.

You'll need to install the JDK 6 (not JRE) and add the JRE 6 tools.jar as a User Entry in the Classpath of the build configuration, listed above the JRE 7 tools.jar.

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

I had the same issue but my solution was to keep the Platform target as Any CPU and UNCHECK Prefer 32-bit checkbox. After I unchecked it I was able to open a connection with the provider.

Use Directory.CreateDirectory before you create the file. It creates the folder recursively for you.

Try this:

public static boolean isAvailable(Context ctx, Intent intent) {
    final PackageManager mgr = ctx.getPackageManager();
    List<ResolveInfo> list =
        mgr.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

At first I had problems escaping the "&" character, then diacritics and special letters were shown as question marks and ended up with the issue OP mentioned.

I looked at the answers and I used @Ringo's suggestion to try Load() method as an alternative. That made me realize that I can deal with my response in other ways not just as a string.

using System.IO.Stream instead of string solved all the issues for me.

var response = await this.httpClient.GetAsync(url);
var responseStream = await response.Content.ReadAsStreamAsync();
var xmlDocument = new XmlDocument();
xmlDocument.Load(responseStream);

The cool thing about Load() is that this method automatically detects the string format of the input XML (for example, UTF-8, ANSI, and so on). See more

Just use a subquery with INNER JOIN, LEFT JOIN or smth else:

DELETE FROM m_productprice
WHERE m_product_id IN
(
  SELECT B.m_product_id
  FROM   m_productprice  B
    INNER JOIN m_product C 
    ON   B.m_product_id = C.m_product_id
  WHERE  C.upc = '7094' 
  AND    B.m_pricelist_version_id = '1000020'
)

to optimize the query,

• use NOT EXISTS instead of IN
• and WITH for large subqueries

My guess is that part of your problem is the parameter lists not matching.

int (* length)();

and

int length(PString * self)

are not the same. It should be int (* length)(PString *);.

...woah, it's Jon!

Edit: and, as mentioned below, your struct pointer is never set to point to anything. The way you're doing it would only work if you were declaring a plain struct, not a pointer.

str = (PString *)malloc(sizeof(PString));

You can find a short collection of useful list functions here.

list.pop(index)

>>> l = ['a', 'b', 'c', 'd']
>>> l.pop(0)
'a'
>>> l
['b', 'c', 'd']
>>> 

del list[index]

>>> l = ['a', 'b', 'c', 'd']
>>> del l[0]
>>> l
['b', 'c', 'd']
>>> 

These both modify your original list.

Others have suggested using slicing:

• Copies the list
• Can return a subset

Also, if you are performing many pop(0), you should look at collections.deque

from collections import deque
>>> l = deque(['a', 'b', 'c', 'd'])
>>> l.popleft()
'a'
>>> l
deque(['b', 'c', 'd'])

• Provides higher performance popping from left end of the list

As you say, hidden-xs is not enough, you have to combine xs and sm class.

Here is links to the official doc about available responsive classes and about the grid system.

• For XtraSmall device : col-xs-__
  
• For SMall device : col-sm-__
  
• For MeDium Device: col-md-__
  
• For LarGe Device : col-lg-__
  
• Make visible only (hidden on other) : visible-md (just visible in medium [not in lg xs or sm])
• Make hidden only (visible on other) : hidden-xs (just hidden in XtraSmall)

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

Please note not to write into /usr/bin but instead into /usr/local/bin. The first one is for app that write themselves the binary into the system and the latest is for that specific usage of making our own system-wide binaries (which is our case here when symlinking).

Also /usr/local/bin is read after /usr/bin and therefore also a good place to override any default app.

Considering this, the right symlinking would be:

ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl

All of you use some strange and complex regex patterns x)

Here's my solution without preg_match :

function getEnumTypes($table, $field) {
    $query = $this->db->prepare("SHOW COLUMNS FROM $table WHERE Field = ?");
    try {$query->execute(array($field));} catch (Exception $e) {error_log($e->getMessage());}
    $types = $query->fetchAll(PDO::FETCH_COLUMN|PDO::FETCH_UNIQUE, 1)[$field];
    return explode("','", trim($types, "enum()'"));
}

Terminate the query with \G in place of ;. For example:

SELECT * FROM sometable\G

This query displays the rows vertically, like this:

*************************** 1. row ***************************
                 Host: localhost
                   Db: mydatabase1
                 User: myuser1
          Select_priv: Y
          Insert_priv: Y
          Update_priv: Y
          ...
*************************** 2. row ***************************
                 Host: localhost
                   Db: mydatabase2

          Select_priv: Y
          Insert_priv: Y
          Update_priv: Y
          ...

• Select App Store tab, Then select Pricing & Availability section
• Under Availability section you will see two options 1) Available in all territories 2) Remove from sale, Kindly refer below screenshot for the same.
• Select remove from sale if you would like to remove from all territories, if you would like to remove from specific territory then click on edit & remove from selected territory.

I'm assuming you want to still see STDERR and STDOUT on the terminal. You could go for Josh Kelley's answer, but I find keeping a tail around in the background which outputs your log file very hackish and cludgy. Notice how you need to keep an exra FD and do cleanup afterward by killing it and technically should be doing that in a trap '...' EXIT.

There is a better way to do this, and you've already discovered it: tee.

Only, instead of just using it for your stdout, have a tee for stdout and one for stderr. How will you accomplish this? Process substitution and file redirection:

command > >(tee -a stdout.log) 2> >(tee -a stderr.log >&2)

Let's split it up and explain:

> >(..)

>(...) (process substitution) creates a FIFO and lets tee listen on it. Then, it uses > (file redirection) to redirect the STDOUT of command to the FIFO that your first tee is listening on.

Same thing for the second:

2> >(tee -a stderr.log >&2)

We use process substitution again to make a tee process that reads from STDIN and dumps it into stderr.log. tee outputs its input back on STDOUT, but since its input is our STDERR, we want to redirect tee's STDOUT to our STDERR again. Then we use file redirection to redirect command's STDERR to the FIFO's input (tee's STDIN).

See http://mywiki.wooledge.org/BashGuide/InputAndOutput

Process substitution is one of those really lovely things you get as a bonus of choosing bash as your shell as opposed to sh (POSIX or Bourne).

In sh, you'd have to do things manually:

out="${TMPDIR:-/tmp}/out.$$" err="${TMPDIR:-/tmp}/err.$$"
mkfifo "$out" "$err"
trap 'rm "$out" "$err"' EXIT
tee -a stdout.log < "$out" &
tee -a stderr.log < "$err" >&2 &
command >"$out" 2>"$err"

Edited:

You should really be using openssl_encrypt() & openssl_decrypt()

As Scott says, Mcrypt is not a good idea as it has not been updated since 2007.

There is even an RFC to remove Mcrypt from PHP - https://wiki.php.net/rfc/mcrypt-viking-funeral

if (isSet($_SESSION['started'])){
    if((mktime() - $_SESSION['started'] - 60*30) > 0){
        //Logout, destroy session, etc.
    }
}
else {
    $_SESSION['started'] = mktime();
}

I was actually wondering this today, and I achieved it by using the php explode function, like this:

HTML Form (in a file I named 'doublevalue.php':

    <form name="car_form" method="post" action="doublevalue_action.php">
            <select name="car" id="car">
                    <option value="">Select Car</option>
                    <option value="BMW|Red">Red BMW</option>
                    <option value="Mercedes|Black">Black Mercedes</option>
            </select>
            <input type="submit" name="submit" id="submit" value="submit">
    </form>

PHP action (in a file I named doublevalue_action.php)

    <?php
            $result = $_POST['car'];
            $result_explode = explode('|', $result);
            echo "Model: ". $result_explode[0]."<br />";
            echo "Colour: ". $result_explode[1]."<br />";
    ?>

As you can see in the first piece of code, we're creating a standard HTML select box, with 2 options. Each option has 1 value, which has a separator (in this instance, '|') to split the values (in this case, model and colour).

On the action page, I'm exploding the results into an array, then calling each one. As you can see, I've separated and labelled them so you can see the effect this is causing.

I hope this helps someone :)

I like to do something like this:

$.fn.exists = function(){
    return this.length > 0 ? this : false;
}

So then you can do something like this:

var firstExistingElement = 
    $('#iDontExist').exists() ||      //<-returns false;
    $('#iExist').exists() ||          //<-gets assigned to the variable 
    $('#iExistAsWell').exists();      //<-never runs

firstExistingElement.doSomething();   //<-executes on #iExist

If the below statment is present in your class then your log4j.properties should be in java source(src) folder , if it is jar executable it should be packed in jar not a seperate file.

static Logger log = Logger.getLogger(MyClass.class);

Thanks,

I think your list of reasons is a pretty comprehensive one.

One particularly bad example that I've encountered more than once goes like this:

    try {
      // do stuff
    } catch (Exception e) {
        e.printStackTrace(); // and swallow the exception
    }

The problem with the above code is that the handling consists entirely of the printStackTrace call: the exception isn't really handled properly nor is it allowed to escape.

On the other hand, as a rule I always log the stack trace whenever there's an unexpected exception in my code. Over the years this policy has saved me a lot of debugging time.

Finally, on a lighter note, God's Perfect Exception.

I am using the following construct, although you might want to avoid shell=True. This gives you the output and error message for any command, and the error code as well:

process = subprocess.Popen(cmd, shell=True,
                           stdout=subprocess.PIPE, 
                           stderr=subprocess.PIPE)

# wait for the process to terminate
out, err = process.communicate()
errcode = process.returncode

If you are not using any primary key, then execute following queries at one single stroke. By replacing values:

# table_name - Your Table Name
# column_name_of_duplicates - Name of column where duplicate entries are found

create table table_name_temp like table_name;
insert into table_name_temp select distinct(column_name_of_duplicates),value,type from table_name group by column_name_of_duplicates;
delete from table_name;
insert into table_name select * from table_name_temp;
drop table table_name_temp

1. create temporary table and store distinct(non duplicate) values
2. make empty original table
3. insert values to original table from temp table
4. delete temp table

It is always advisable to take backup of database before you play with it.

You can do it by using Apache Commons IO without worrying about internal details.

Use org.apache.commons.io.FileUtils.readFileToByteArray(File file) which return data of type byte[].

Another solution is using OpenStruct. Its pretty straight forward and clean.

https://ruby-doc.org/stdlib-2.3.1/libdoc/ostruct/rdoc/OpenStruct.html

Example:

# bar.rb
require 'ostruct' # not needed when using Rails

# by patching Array you have a simple way of creating a ENUM-style
class Array
   def to_enum(base=0)
      OpenStruct.new(map.with_index(base).to_h)
   end
end

class Bar

    MY_ENUM = OpenStruct.new(ONE: 1, TWO: 2, THREE: 3)
    MY_ENUM2 = %w[ONE TWO THREE].to_enum

    def use_enum (value)
        case value
        when MY_ENUM.ONE
            puts "Hello, this is ENUM 1"
        when MY_ENUM.TWO
            puts "Hello, this is ENUM 2"
        when MY_ENUM.THREE
            puts "Hello, this is ENUM 3"
        else
            puts "#{value} not found in ENUM"
        end
    end

end

# usage
foo = Bar.new    
foo.use_enum 1
foo.use_enum 2
foo.use_enum 9


# put this code in a file 'bar.rb', start IRB and type: load 'bar.rb'

RewriteEngine, DirectoryIndex in .htaccess file of CodeIgniter apps

I just changed the .htaccess file contents and as shown in the following links answer. And tried refreshing the page (which didn't work, and couldn't find the request to my controller) it worked.

Then just because of my doubt I undone the changes I did to my .htaccess inside my public_html folder back to original .htaccess content. So it's now as follows (which is originally it was):

DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]

And now also it works.

Hint: Seems like before the Rewrite Rules haven't been clearly setup within the Server context.

My file structure is as follows:

/
|- gheapp
|    |- application
|    L- system
|
|- public_html
|    |- .htaccess
|    L- index.php

And in the index.php I have set up the following paths to the system and the application:

$system_path = '../gheapp/system';
$application_folder = '../gheapp/application';

Note: by doing so, our application source code becomes hidden to the public at first.

Please, if you guys find anything wrong with my answer, comment and re-correct me!
Hope beginners would find this answer helpful.

Thanks!

None of the older answers describe exit status 2 correctly. Contrary to what they claim, status 2 is what your command line utilities actually return when called improperly. (Yes, an answer can be nine years old, have hundreds of upvotes, and still be wrong.)

Here is the real, long-standing exit status convention for normal termination, i.e. not by signal:

• Exit status 0: success
• Exit status 1: "failure", as defined by the program
• Exit status 2: command line usage error

For example, diff returns 0 if the files it compares are identical, and 1 if they differ. By long-standing convention, unix programs return exit status 2 when called incorrectly (unknown options, wrong number of arguments, etc.) For example, diff -N, grep -Y or diff a b c will all result in $? being set to 2. This is and has been the practice since the early days of Unix in the 1970s.

The accepted answer explains what happens when a command is terminated by a signal. In brief, termination due to an uncaught signal results in exit status 128+[<signal number>. E.g., termination by SIGINT (signal 2) results in exit status 130.

Notes

1. Several answers define exit status 2 as "Misuse of bash builtins". This applies only when bash (or a bash script) exits with status 2. Consider it a special case of incorrect usage error.

2. In sysexits.h, mentioned in the most popular answer, exit status EX_USAGE ("command line usage error") is defined to be 64. But this does not reflect reality: I am not aware of any common Unix utility that returns 64 on incorrect invocation (examples welcome). Careful reading of the source code reveals that sysexits.h is aspirational, rather than a reflection of true usage:

    *    This include file attempts to categorize possible error
    *    exit statuses for system programs, notably delivermail
    *    and the Berkeley network.
   
    *    Error numbers begin at EX__BASE [64] to reduce the possibility of 
    *    clashing with oth­er exit statuses that random programs may 
    *    already return. 
   

   In other words, these definitions do not reflect the common practice at the time (1993) but were intentionally incompatible with it. More's the pity.

In the other question I suggested autoexnt. That is also possible in this situation. Just set the service to run manually (ie not automatic at startup). When you want to run your batch, modify the autoexnt.bat file to call the batch file you want, and start the autoexnt service.

The batchfile to start this, can look like this (untested):

echo call c:\path\to\batch.cmd %* > c:\windows\system32\autoexnt.bat
net start autoexnt

Note that batch files started this way run as the system user, which means you do not have access to network shares automatically. But you can use net use to connect to a remote server.

You have to download the Windows 2003 Resource Kit to get it. The Resource Kit can also be installed on other versions of windows, like Windows XP.

Use string interpolation decimalVar:0.00

In this example ordering adds no information - the COUNT of a set is the same whatever order it is in!

If you were selecting something that did depend on order, you would need to do one of the things the error message tells you - use TOP or FOR XML

Reason

This does not work, because Chrome forbids any kind of inline code in extensions via Content Security Policy.

Inline JavaScript will not be executed. This restriction bans both inline <script> blocks and inline event handlers (e.g. <button onclick="...">).

How to detect

If this is indeed the problem, Chrome would produce the following error in the console:

Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' chrome-extension-resource:". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution.

To access a popup's JavaScript console (which is useful for debug in general), right-click your extension's button and select "Inspect popup" from the context menu.

More information on debugging a popup is available here.

How to fix

One needs to remove all inline JavaScript. There is a guide in Chrome documentation.

Suppose the original looks like:

<a onclick="handler()">Click this</a> <!-- Bad -->

One needs to remove the onclick attribute and give the element a unique id:

<a id="click-this">Click this</a> <!-- Fixed -->

And then attach the listener from a script (which must be in a .js file, suppose popup.js):

// Pure JS:
document.addEventListener('DOMContentLoaded', function() {
  document.getElementById("click-this").addEventListener("click", handler);
});

// The handler also must go in a .js file
function handler() {
  /* ... */
}

Note the wrapping in a DOMContentLoaded event. This ensures that the element exists at the time of execution. Now add the script tag, for instance in the <head> of the document:

<script src="popup.js"></script>

Alternative if you're using jQuery:

// jQuery
$(document).ready(function() {
  $("#click-this").click(handler);
});

Relaxing the policy

Q: The error mentions ways to allow inline code. I don't want to / can't change my code, how do I enable inline scripts?

A: Despite what the error says, you cannot enable inline script:

There is no mechanism for relaxing the restriction against executing inline JavaScript. In particular, setting a script policy that includes 'unsafe-inline' will have no effect.

Update: Since Chrome 46, it's possible to whitelist specific inline code blocks:

As of Chrome 46, inline scripts can be whitelisted by specifying the base64-encoded hash of the source code in the policy. This hash must be prefixed by the used hash algorithm (sha256, sha384 or sha512). See Hash usage for <script> elements for an example.

However, I do not readily see a reason to use this, and it will not enable inline attributes like onclick="code".

Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing

#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()

As most of the answers suggest, LISTAGG is the obvious option. However, one annoying aspect with LISTAGG is that if the total length of concatenated string exceeds 4000 characters( limit for VARCHAR2 in SQL ), the below error is thrown, which is difficult to manage in Oracle versions upto 12.1

ORA-01489: result of string concatenation is too long

A new feature added in 12cR2 is the ON OVERFLOW clause of LISTAGG. The query including this clause would look like:

SELECT pid, LISTAGG(Desc, ' ' on overflow truncate) WITHIN GROUP (ORDER BY seq) AS desc
FROM B GROUP BY pid;

The above will restrict the output to 4000 characters but will not throw the ORA-01489 error.

These are some of the additional options of ON OVERFLOW clause:

• ON OVERFLOW TRUNCATE 'Contd..' : This will display 'Contd..' at the end of string (Default is ... )
• ON OVERFLOW TRUNCATE '' : This will display the 4000 characters without any terminating string.
• ON OVERFLOW TRUNCATE WITH COUNT : This will display the total number of characters at the end after the terminating characters. Eg:- '...(5512)'
• ON OVERFLOW ERROR : If you expect the LISTAGG to fail with the ORA-01489 error ( Which is default anyway ).

str.replace(/^.+?\"|^.|\".+/, '');

This is sometimes bad to use when you wanna select what else to remove between "" and you cannot use it more than twice in one string. All it does is select whatever is not in between "" and replace it with nothing.

Even for me it is a bit confusing, but ill try to explain it. ^.+? (not anything OPTIONAL) till first " then | Or/stop (still researching what it really means) till/at ^. has selected nothing until before the 2nd " using (| stop/at). And select all that comes after with .+.

Getting height transitions to work can be a bit tricky mainly because you have to know the height to animate for. This is further complicated by padding in the element to be animated.

Here is what I came up with:

use a style like this:

    .slideup, .slidedown {
        max-height: 0;            
        overflow-y: hidden;
        -webkit-transition: max-height 0.8s ease-in-out;
        -moz-transition: max-height 0.8s ease-in-out;
        -o-transition: max-height 0.8s ease-in-out;
        transition: max-height 0.8s ease-in-out;
    }
    .slidedown {            
        max-height: 60px ;  // fixed width                  
    }

Wrap your content into another container so that the container you're sliding has no padding/margins/borders:

  <div id="Slider" class="slideup">
    <!-- content has to be wrapped so that the padding and
            margins don't effect the transition's height -->
    <div id="Actual">
            Hello World Text
        </div>
  </div>

Then use some script (or declarative markup in binding frameworks) to trigger the CSS classes.

  $("#Trigger").click(function () {
    $("#Slider").toggleClass("slidedown slideup");
  });

Example here: http://plnkr.co/edit/uhChl94nLhrWCYVhRBUF?p=preview

This works fine for fixed size content. For a more generic soltution you can use code to figure out the size of the element when the transition is activated. The following is a jQuery plug-in that does just that:

$.fn.slideUpTransition = function() {
    return this.each(function() {
        var $el = $(this);
        $el.css("max-height", "0");
        $el.addClass("height-transition-hidden");
    });
};

$.fn.slideDownTransition = function() {
    return this.each(function() {
        var $el = $(this);
        $el.removeClass("height-transition-hidden");

        // temporarily make visible to get the size
        $el.css("max-height", "none");
        var height = $el.outerHeight();

        // reset to 0 then animate with small delay
        $el.css("max-height", "0");

        setTimeout(function() {
            $el.css({
                "max-height": height
            });
        }, 1);
    });
};

which can be triggered like this:

$("#Trigger").click(function () {

    if ($("#SlideWrapper").hasClass("height-transition-hidden"))
        $("#SlideWrapper").slideDownTransition();
    else
        $("#SlideWrapper").slideUpTransition();
});

against markup like this:

<style>
#Actual {
    background: silver;
    color: White;
    padding: 20px;
}

.height-transition {
    -webkit-transition: max-height 0.5s ease-in-out;
    -moz-transition: max-height 0.5s ease-in-out;
    -o-transition: max-height 0.5s ease-in-out;
    transition: max-height 0.5s ease-in-out;
    overflow-y: hidden;            
}
.height-transition-hidden {            
    max-height: 0;            
}
</style>
<div id="SlideWrapper" class="height-transition height-transition-hidden">
    <!-- content has to be wrapped so that the padding and
        margins don't effect the transition's height -->
    <div id="Actual">
     Your actual content to slide down goes here.
    </div>
</div>

I wrote this up recently in a blog post if you're interested in more detail:

http://weblog.west-wind.com/posts/2014/Feb/22/Using-CSS-Transitions-to-SlideUp-and-SlideDown

You have an extra -c you need to get rid of:

psexec -u administrator -p force \\135.20.230.160 -s -d cmd.exe /c "C:\Amitra\bogus.bat"

>= ES6:

Number.MIN_SAFE_INTEGER;
Number.MAX_SAFE_INTEGER;

<= ES5

From the reference:

Number.MAX_VALUE;
Number.MIN_VALUE;

console.log('MIN_VALUE', Number.MIN_VALUE);
console.log('MAX_VALUE', Number.MAX_VALUE);

console.log('MIN_SAFE_INTEGER', Number.MIN_SAFE_INTEGER); //ES6
console.log('MAX_SAFE_INTEGER', Number.MAX_SAFE_INTEGER); //ES6

Have a look at this one: http://aquantum-demo.appspot.com/file-upload

It also handles multiple file upload!

You can use the six library to support both Python 2 and 3:

import six
if isinstance(value, six.string_types):
    handle_string(value)

It may happen that "this.checked" is always "on". Therefore, I recommend:

$('#checkbox').change(function() {
  if ($(this).is(':checked')) {
    console.log('Checked');
  } else {
    console.log('Unchecked');
  }
});

You must press enter after continuation character

Note: Space after continuation character leads to error

cost = {"apples": [3.5, 2.4, 2.3], "bananas": [1.2, 1.8]}

0.9 * average(cost["apples"]) + \ """enter here"""
0.1 * average(cost["bananas"])

Maybe a little late, but using different drivers altogether is overkill for a case of user error:

db.dbConnect("jdbc:sqlserver://localhost:1433/muff", "user", "pw" );

should be either one of these:

db.dbConnect("jdbc:sqlserver://localhost\muff", "user", "pw" );

(using named pipe) or:

db.dbConnect("jdbc:sqlserver://localhost:1433", "user", "pw" );

using port number directly; you can leave out 1433 because it's the default port, leaving:

db.dbConnect("jdbc:sqlserver://localhost", "user", "pw" );

The json module already implements some basic pretty printing with the indent parameter that specifies how many spaces to indent by:

>>> import json
>>>
>>> your_json = '["foo", {"bar":["baz", null, 1.0, 2]}]'
>>> parsed = json.loads(your_json)
>>> print(json.dumps(parsed, indent=4, sort_keys=True))
[
    "foo", 
    {
        "bar": [
            "baz", 
            null, 
            1.0, 
            2
        ]
    }
]

To parse a file, use json.load():

with open('filename.txt', 'r') as handle:
    parsed = json.load(handle)

Set objShell = WScript.CreateObject("WScript.Shell") 
skey = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{9A25302D-30C0-39D9-BD6F-21E6EC160475}\"
with CreateObject("WScript.Shell")
    on error resume next            ' turn off error trapping
    sValue = .regread(sKey)       ' read attempt
    bFound = (err.number = 0)     ' test for success
end with
if bFound then
    msgbox "exists"
else
  msgbox "not exists" 
End If

If you using latest Owl Carousel 2 version. You can replace the Navigation text by fontawesome icon. Code is below.

$('.your-class').owlCarousel({
        loop: true,
        items: 1, // Select Item Number
        autoplay:true,
        dots: false,
        nav: true,
        navText: ["<i class='fa fa-long-arrow-left'></i>","<i class='fa fa-long-arrow-right'></i>"],

    });

Try these if you use maven. I use maven for my project and when I do mvn clean install and try to run a program it throws the exception. So, I clean the project and run it again and it works for me.

I use eclipse IDE.

For Class Not Found Exception when running Junit test, try running mvn clean test once. It will compile all the test classes.

std::copy cannot be used to insert into an empty container. To do that, you need to use an insert_iterator like so:

std::set<double> input;
input.insert(5);
input.insert(6);

std::vector<double> output;
std::copy(input.begin(), input.end(), inserter(output, output.begin())); 

use setVisibility in button or imageViwe or .....
To remove button in java code:

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(Button.GONE);

To transparent Button in java code

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(Button.INVISIBLE);

You should make you button xml code like below:

<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"/>

hidden:
visibility: gone
show:
visibility: invisible
visibility: visible

None of the other answers worked for me. For me the device registered with eclipse after I rebooted the phone. Process for that is going to vary by phone model.

Try this.

Dim Workbk as workbook
Set Workbk = thisworkbook

Now everything you program will apply just for your containing macro workbook.

I think it should be

 $('#fileinput').val();

By using the column that the index is applied to within your conditions, it will be included automatically. You do not have to use it, but it will speed up queries when it is used.

SELECT * FROM TABLE WHERE attribute = 'value'

Will use the appropriate index.

I figured this wouldn't be UTF, but I just found a pretty simple solution that seems to work...

Get-Content path/to/file.ext | out-file -encoding ASCII targetFile.ext

For me this results in a utf-8 without bom file regardless of the source format.

The problem is you either haven't closed your if or you need an elseif:

create procedure checando(
    in nombrecillo varchar(30),
    in contrilla varchar(30), 
    out resultado int)
begin 

    if exists (select * from compas where nombre = nombrecillo and contrasenia = contrilla) then
        set resultado = 0;
    elseif exists (select * from compas where nombre = nombrecillo) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
end;

I ended up using a definition list with an unordered list inside it. It solves the issue of the unwanted space above the list without needing to change every paragraph tag.

<dl><dt>Text</dt>
<dd><ul><li>First item</li>
<li>Second item</li></ul></dd></dl>

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET NEWPAGE NONE
SET PAGESIZE 0
SET SPACE 0
SET LINESIZE 16000
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |

spool &1..txt

@@&1

spool off
exit

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

sqlplus -S user/password@database @dump.sql my_real_query.sql

The result is written to a file

my_real_query.sql.txt

.

You can use like the following

string result = null;
object value = cmd.ExecuteScalar();
 if (value != null)
 {
    result = value.ToString();
 }     
 conn.Close();
return result;

Did you try export directive of Make itself (assuming that you use GNU Make)?

export PATH := bin:$(PATH)

test all:
    x

Also, there is a bug in you example:

test all:
    PATH=bin:${PATH}
    @echo $(PATH)
    x

First, the value being echoed is an expansion of PATH variable performed by Make, not the shell. If it prints the expected value then, I guess, you've set PATH variable somewhere earlier in your Makefile, or in a shell that invoked Make. To prevent such behavior you should escape dollars:

test all:
    PATH=bin:$$PATH
    @echo $$PATH
    x

Second, in any case this won't work because Make executes each line of the recipe in a separate shell. This can be changed by writing the recipe in a single line:

test all:
    export PATH=bin:$$PATH; echo $$PATH; x

You can detect a lot of heap corruption problems by enabling Page Heap for your application . To do this you need to use gflags.exe that comes as a part of Debugging Tools For Windows

Run Gflags.exe and in the Image file options for your executable, check "Enable Page Heap" option.

Now restart your exe and attach to a debugger. With Page Heap enabled, the application will break into debugger whenever any heap corruption occurs.

You can use AJAX for that. Whenever you scan a barcode, your scanner will act as if it is a keyboard typing into your input type="text" components. With JavaScript, capture the corresponding event, and send HTTP REQUEST and process responses accordingly.

This is an older thread, but I just searched and found it. I am new to using Web Developer Tools: primarily Firefox Developer Tools (Firefox v.51), but also Chrome DevTools (Chrome v.56)].

I wasn't able to run functions from the Developer Tools console, but I then found this

https://developer.mozilla.org/en-US/docs/Tools/Scratchpad

and I was able to add code to the Scratchpad, highlight and run a function, outputted to console per the attched screenshot.

I also added the Chrome "Scratch JS" extension: it looks like it provides the same functionality as the Scratchpad in Firefox Developer Tools (screenshot below).

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

What about this? I presume it can be counted on to handle dates before 1970 and after 2038.

target_date_time_ms = 200000 # or whatever
base_datetime = datetime.datetime( 1970, 1, 1 )
delta = datetime.timedelta( 0, 0, 0, target_date_time_ms )
target_date = base_datetime + delta

as mentioned in the Python standard lib:

fromtimestamp() may raise ValueError, if the timestamp is out of the range of values supported by the platform C localtime() or gmtime() functions. It’s common for this to be restricted to years in 1970 through 2038.

If your test and webapp are in the same Maven project, you can use a property in the project POM. Then you can filter certain files which will allow Maven to set the property in those files. There are different ways to filter, but the most common is during the resources phase - http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-description.html

If the test and webapp are in different Maven projects, you can put the property in settings.xml, which is in your maven repository folder (C:\Documents and Settings\username.m2) on Windows. You will still need to use filtering or some other method to read the property into your test and webapp.

There is a subtle issue here that is a bit of a gotcha.

The toString() method has a base implementation in Object. CharSequence is an interface; and although the toString() method appears as part of that interface, there is nothing at compile-time that will force you to override it and honor the additional constraints that the CharSequence toString() method's javadoc puts on the toString() method; ie that it should return a string containing the characters in the order returned by charAt().

Your IDE won't even help you out by reminding that you that you probably should override toString(). For example, in intellij, this is what you'll see if you create a new CharSequence implementation: http://puu.sh/2w1RJ. Note the absence of toString().

If you rely on toString() on an arbitrary CharSequence, it should work provided the CharSequence implementer did their job properly. But if you want to avoid any uncertainty altogether, you should use a StringBuilder and append(), like so:

final StringBuilder sb = new StringBuilder(charSequence.length());
sb.append(charSequence);
return sb.toString();

It looks like a bug http://code.google.com/p/android/issues/detail?id=939.

Finally I have to write something like this:

 <stroke android:width="3dp"
         android:color="#555555"
         />

 <padding android:left="1dp"
          android:top="1dp"
          android:right="1dp"
          android:bottom="1dp"
          /> 

 <corners android:radius="1dp"
  android:bottomRightRadius="2dp" android:bottomLeftRadius="0dp" 
  android:topLeftRadius="2dp" android:topRightRadius="0dp"/> 

I have to specify android:bottomRightRadius="2dp" for left-bottom rounded corner (another bug here).

Since you're using requests, you should use the response's json method.

import requests

response = requests.get(...)
data = response.json()

It autodetects which decoder to use.

You might also checkout http://www.concretejs.com which is a modern, lightweight, Html5 canvas framework that enables hit detection, layering, and lots of other peripheral things. You can do things like this:

var wrapper = new Concrete.Wrapper({
  width: 500,
  height: 300,
  container: el
});

var layer1 = new Concrete.Layer();
var layer2 = new Concrete.Layer();

wrapper.add(layer1).add(layer2);

// draw stuff
layer1.sceneCanvas.context.fillStyle = 'red';
layer1.sceneCanvas.context.fillRect(0, 0, 100, 100);

// reorder layers
layer1.moveUp();

// destroy a layer
layer1.destroy();

This should get you started

If you want to disable the highlight for a single list view item, but keep the cell enabled, set the background color for that cell to disable the highlighting.

For instance, in your cell layout, set android:background="@color/white"

I realize this has been well answered but here's a comparison between "$@" $@ "$*" and $*

Contents of test script:

# cat ./test.sh
#!/usr/bin/env bash
echo "================================="

echo "Quoted DOLLAR-AT"
for ARG in "$@"; do
    echo $ARG
done

echo "================================="

echo "NOT Quoted DOLLAR-AT"
for ARG in $@; do
    echo $ARG
done

echo "================================="

echo "Quoted DOLLAR-STAR"
for ARG in "$*"; do
    echo $ARG
done

echo "================================="

echo "NOT Quoted DOLLAR-STAR"
for ARG in $*; do
    echo $ARG
done

echo "================================="

Now, run the test script with various arguments:

# ./test.sh  "arg with space one" "arg2" arg3
=================================
Quoted DOLLAR-AT
arg with space one

=================================
NOT Quoted DOLLAR-AT

Just convert the jpg format image into png format. It will work 100%.

The reason this puts NaN into a column is because df.index and the Index of your right-hand-side object are different. @zach shows the proper way to assign a new column of zeros. In general, pandas tries to do as much alignment of indices as possible. One downside is that when indices are not aligned you get NaN wherever they aren't aligned. Play around with the reindex and align methods to gain some intuition for alignment works with objects that have partially, totally, and not-aligned-all aligned indices. For example here's how DataFrame.align() works with partially aligned indices:

In [7]: from pandas import DataFrame

In [8]: from numpy.random import randint

In [9]: df = DataFrame({'a': randint(3, size=10)})

In [10]:

In [10]: df
Out[10]:
   a
0  0
1  2
2  0
3  1
4  0
5  0
6  0
7  0
8  0
9  0

In [11]: s = df.a[:5]

In [12]: dfa, sa = df.align(s, axis=0)

In [13]: dfa
Out[13]:
   a
0  0
1  2
2  0
3  1
4  0
5  0
6  0
7  0
8  0
9  0

In [14]: sa
Out[14]:
0     0
1     2
2     0
3     1
4     0
5   NaN
6   NaN
7   NaN
8   NaN
9   NaN
Name: a, dtype: float64

Careful - append() will append HTML, and you may run into cross-site-scripting problems if you use it all the time and a user makes you append('<script>alert("Hello")</script>').

Use text() to replace element content with text, or append(document.createTextNode(x)) to append a text node.

The stargazer package is another good option. It supports objects from many commonly used functions and packages (lm, glm, svyreg, survival, pscl, AER), as well as from zelig. In addition to regression tables, it can also output summary statistics for data frames, or directly output the content of data frames.

try

val f = sc.textFile("./README.md")

I had the same problem, in my case i resolved it by:

1) going to File-->Project Structure---->Global libraries 2) looking for jfxrt.jar included as default in the jdk1.8.0_241\lib (after installing it) 3)click on + on top left to add new global library and i specified the path of my jdk1.8.0_241 Ex :(C:\Program Files\Java\jdk1.8.0_241).

I hope this will help you

There is 2 alternative which I use (for jasmine 2)

This one is not quite explicit because it seems that the function is actually a fake.

test = createSpy().and.callFake(test); 

The second more verbose, more explicit, and "cleaner":

test = createSpy('testSpy', test).and.callThrough();

-> jasmine source code to see the second argument

after your pc connects to other pc use these 4 step:
4 steps:
1- Edit this file: httpd.conf
for that click on wamp server and select Apache and select httpd.conf
2- Find this text: Deny from all
in the below tag:

  <Directory "c:/wamp/www"><!-- maybe other url-->

    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see

Don't forget restart Apache or all servises!!!

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

You could use a Mixin.

/// <summary>
/// Adds "mixins" to the Boolean class.
/// </summary>
public static class BooleanMixins
{
    /// <summary>
    /// Converts the value of this instance to its equivalent string representation (either "Yes" or "No").
    /// </summary>
    /// <param name="boolean"></param>
    /// <returns>string</returns>
    public static string ToYesNoString(this Boolean boolean)
    {
        return boolean ? "Yes" : "No";
    }
}

you can swipe the key and the value. For example

        String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
        int[] v = {341, 273, 278, 329, 445};
        TreeMap<Integer,String>a=new TreeMap();
        for (int i = 0; i < k.length; i++) 
           a.put(v[i],k[i]);            
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
        a.remove(a.firstEntry().getKey());
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());

Here there is a simple script to easily manage the text style in bash shell promt:

https://github.com/ferromauro/bash-palette

Import the code using:

source bash-palette.sh

Use the imported variable in echo command (use the -e option!):

echo -e ${PALETTE_GREEN}Color Green${PALETTE_RESET}

It is possible to combine more elements:

echo -e ${PALETTE_GREEN}${PALETTE_BLINK}${PALETTE_RED_U}Green Blinking Text over Red Background${PALETTE_RESET}

In the parent POM, the main difference between the <dependencies> and <dependencyManagement> is this:

Artifacts specified in the <dependencies> section will ALWAYS be included as a dependency of the child module(s).

Artifacts specified in the <dependencyManagement> section will only be included in the child module if they were also specified in the section of the child module itself. Why is it good you ask? because you specify the version and/or scope in the parent, and you can leave them out when specifying the dependencies in the child POM. This can help you use unified versions for dependencies for child modules, without specifying the version in each child module.

To find all local IPv4 addresses:

IPAddress[] ipv4Addresses = Array.FindAll(
    Dns.GetHostEntry(string.Empty).AddressList,
    a => a.AddressFamily == AddressFamily.InterNetwork);

or use Array.Find or Array.FindLast if you just want one.

From Python 3.0 changelog;

The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.

From the Python 3 email documentation it can be seen that io.StringIO should be used instead:

from io import StringIO
from email.generator import Generator
fp = StringIO()
g = Generator(fp, mangle_from_=True, maxheaderlen=60)
g.flatten(msg)
text = fp.getvalue()

Reference: https://docs.python.org/3/library/io.html

Why not just:

int plusIndex = s.indexOf("+");
if (plusIndex != -1) {
    String before = s.substring(0, plusIndex);
    // Use before
}

It's not really clear why your original version didn't work, but then you didn't say what actually happened. If you want to split not using regular expressions, I'd personally use Guava:

Iterable<String> bits = Splitter.on('+').split(s);
String firstPart = Iterables.getFirst(bits, "");

If you're going to use split (either the built-in version or Guava) you don't need to check whether it contains + first - if it doesn't there'll only be one result anyway. Obviously there's a question of efficiency, but it's simpler code:

// Calling split unconditionally
String[] parts = s.split("\\+");
s = parts[0];

Note that writing String[] parts is preferred over String parts[] - it's much more idiomatic Java code.

This will probably be added in coming updates. But in the meantime, to accomplish this you can use reflection.

Create a custom view extending from BottomNavigationView and access some of its fields.

public class SelectableBottomNavigationView extends BottomNavigationView {

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

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

    public SelectableBottomNavigationView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public void setSelected(int index) {
        try {
            Field f = BottomNavigationView.class.getDeclaredField("mMenuView");
            f.setAccessible(true);
            BottomNavigationMenuView menuView = (BottomNavigationMenuView) f.get(this);

            try {
                Method method = menuView.getClass().getDeclaredMethod("activateNewButton", Integer.TYPE);
                method.setAccessible(true);
                method.invoke(menuView, index);
            } catch (SecurityException | NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
                e.printStackTrace();
            }
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        }
    }

}

And then use it in your xml layout file.

<com.your.app.SelectableBottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:itemBackground="@color/primary"
        app:itemIconTint="@drawable/nav_item_color_state"
        app:itemTextColor="@drawable/nav_item_color_state"
        app:menu="@menu/bottom_navigation_menu"/>

I had to send my context through a constructor on a custom adapter displayed in a fragment and had this issue with getApplicationContext(). I solved it with:

this.getActivity().getWindow().getContext() in the fragments' onCreate callback.

You can use a simple JS snippet to set the value of a hidden field. When posted back you know if JS was enabled or not.

Or you can try to open a popup window that you close rapidly (but that might be visible).

Also you have the NOSCRIPT tag that you can use to show text for browsers with JS disabled.

This is a clear answer to your question: How do I force my .NET application to run as administrator?

Summary:

Right Click on project -> Add new item -> Application Manifest File

Then in that file change a line like this:

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

Compile and run!

for me replace doesn't work... try this code:

str = str.split(""").join('"');

autoResetEvent.WaitOne()

is similar to

try
{
   manualResetEvent.WaitOne();
}
finally
{
   manualResetEvent.Reset();
}

as an atomic operation

There's always reduce (being deprecated to functools):

>>> x = [ [ 'a', 'b'], ['c'] ]
>>> for el in reduce(lambda a,b: a+b, x, []):
...  print el
...
__main__:1: DeprecationWarning: reduce() not supported in 3.x; use functools.reduce()
a
b
c
>>> import functools
>>> for el in functools.reduce(lambda a,b: a+b, x, []):
...   print el
...
a
b
c
>>>

Unfortunately the plus operator for list concatenation can't be used as a function -- or fortunate, if you prefer lambdas to be ugly for improved visibility.

Perhaps this could be another possible replace :

@Data
public class MyMap {
    @Delegate //lombok
    private HashMap<String, String> value;
}

strtolower is lacking in several of the proposed solutions, RFC2616 (HTTP/1.1) defines header fields as case-insensitive entities. The whole thing, not just the value part.

So suggestions like only parsing HTTP_ entries are wrong.

Better would be like this:

if (!function_exists('getallheaders')) {
    foreach ($_SERVER as $name => $value) {
        /* RFC2616 (HTTP/1.1) defines header fields as case-insensitive entities. */
        if (strtolower(substr($name, 0, 5)) == 'http_') {
            $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
        }
    }
    $this->request_headers = $headers;
} else {
    $this->request_headers = getallheaders();
}

Notice the subtle differences with previous suggestions. The function here also works on php-fpm (+nginx).

Following this question, in Angular 7.2 you can pass data from parent to child using the history state. So you can do something like

Send:

this.router.navigate(['action-selection'], { state: { example: 'bar' } });

Retrieve:

constructor(private router: Router) {
  console.log(this.router.getCurrentNavigation().extras.state.example);
}

But be careful to be consistent. For example, suppose you want to display a list on a left side bar and the details of the selected item on the right by using a router-outlet. Something like:

Item 1 (x) | ..............................................

Item 2 (x) | ......Selected Item Details.......

Item 3 (x) | ..............................................

Item 4 (x) | ..............................................

Now, suppose you have already clicked some items. Clicking the browsers back buttons will show the details from the previous item. But what if, meanwhile, you have clicked the (x) and delete from your list that item? Then performing the back click, will show you the details of a deleted item.

Another scenario for Static method.

Yes, Static method is of the class not of the object. And when you don't want anyone to initialize the object of the class or you don't want more than one object, you need to use Private constructor and so the static method.

Here, we have private constructor and using static method we are creating a object.

Ex::

public class Demo {

        private static Demo obj = null;         
        private Demo() {
        }

        public static Demo createObj() {

            if(obj == null) {
               obj = new Demo();
            }
            return obj;
        }
}

Demo obj1 = Demo.createObj();

Here, Only 1 instance will be alive at a time.

Github's libgit2 binding, pygit2 provides a one-liner cloning a remote directory:

clone_repository(url, path, 
    bare=False, repository=None, remote=None, checkout_branch=None, callbacks=None)

Python uses quotes something like this:

mystringliteral1="this is a string with 'quotes'"
mystringliteral2='this is a string with "quotes"'
mystringliteral3="""this is a string with "quotes" and more 'quotes'"""
mystringliteral4='''this is a string with 'quotes' and more "quotes"'''
mystringliteral5='this is a string with \"quotes\"'
mystringliteral6='this is a string with \042quotes\042'
mystringliteral6='this is a string with \047quotes\047'

print mystringliteral1
print mystringliteral2
print mystringliteral3
print mystringliteral4
print mystringliteral5
print mystringliteral6

Which gives the following output:

this is a string with 'quotes'
this is a string with "quotes"
this is a string with "quotes" and more 'quotes'
this is a string with 'quotes' and more "quotes"
this is a string with "quotes"
this is a string with 'quotes'

EDIT: If you're not stuck with Java <6 and speed is not critical and/or translation table is too limiting, use answer by David. The point is to use Normalizer (introduced in Java 6) instead of translation table inside the loop.

While this is not "perfect" solution, it works well when you know the range (in our case Latin1,2), worked before Java 6 (not a real issue though) and is much faster than the most suggested version (may or may not be an issue):

    /**
 * Mirror of the unicode table from 00c0 to 017f without diacritics.
 */
private static final String tab00c0 = "AAAAAAACEEEEIIII" +
    "DNOOOOO\u00d7\u00d8UUUUYI\u00df" +
    "aaaaaaaceeeeiiii" +
    "\u00f0nooooo\u00f7\u00f8uuuuy\u00fey" +
    "AaAaAaCcCcCcCcDd" +
    "DdEeEeEeEeEeGgGg" +
    "GgGgHhHhIiIiIiIi" +
    "IiJjJjKkkLlLlLlL" +
    "lLlNnNnNnnNnOoOo" +
    "OoOoRrRrRrSsSsSs" +
    "SsTtTtTtUuUuUuUu" +
    "UuUuWwYyYZzZzZzF";

/**
 * Returns string without diacritics - 7 bit approximation.
 *
 * @param source string to convert
 * @return corresponding string without diacritics
 */
public static String removeDiacritic(String source) {
    char[] vysl = new char[source.length()];
    char one;
    for (int i = 0; i < source.length(); i++) {
        one = source.charAt(i);
        if (one >= '\u00c0' && one <= '\u017f') {
            one = tab00c0.charAt((int) one - '\u00c0');
        }
        vysl[i] = one;
    }
    return new String(vysl);
}

Tests on my HW with 32bit JDK show that this performs conversion from àèélštc89FDC to aeelstc89FDC 1 million times in ~100ms while Normalizer way makes it in 3.7s (37x slower). In case your needs are around performance and you know the input range, this may be for you.

Enjoy :-)

The models.CharField is a CharField representation of one of the choices. What you want is a set of choices. This doesn't seem to be implemented in django (yet).

You could use a many to many field for it, but that has the disadvantage that the choices have to be put in a database. If you want to use hard coded choices, this is probably not what you want.

There is a django snippet at http://djangosnippets.org/snippets/1200/ that does seem to solve your problem, by implementing a ModelField MultipleChoiceField.

MySQL does allow NULL values for datetime fields. I just tested it:

mysql> create table datetimetest (testcolumn datetime null default null);
Query OK, 0 rows affected (0.10 sec)

mysql> insert into datetimetest (testcolumn) values (null);
Query OK, 1 row affected (0.00 sec)

mysql> select * from datetimetest;
+------------+
| testcolumn |
+------------+
| NULL       | 
+------------+
1 row in set (0.00 sec)

I'm using this version:

mysql> select version();
+-----------+
| version() |
+-----------+
| 5.0.45    | 
+-----------+
1 row in set (0.03 sec)

EDIT #1: I see in your edit that the error message you are getting in PHP indicates that you are passing an empty string (i.e. ''), not null. An empty string is different than null and is not a valid datetime value which is why you are getting that error message. You must pass the special sql keyword null if that's what you mean. Also, don't put any quotes around the word null. See my insert statement above for an example of how to insert null.

EDIT #2: Are you using PDO? If so, when you bind your null param, make sure to use the [PDO::PARAM_NULL][1] type when binding a null. See the answer to this stackoverflow question on how to properly insert null using PDO.

Git uses "the index" to prepare commits. You can add and remove changes from the index before you commit (in your paste you already have deleted ~10 files with git rm). When the index looks like you want it, run git commit.

Usually this will fire up vim. To insert text hit i, <esc> goes back to normal mode, hit ZZ to save and quit (ZQ to quit without saving). voilà, there's your commit

What you can do is:

1. Update your local git repo:

   git fetch

2. Build a local branch and checkout on it:

   git branch pouet && git checkout pouet

3. Apply the commit you want on this branch:

   git cherry-pick abcdefabcdef

   (abcdefabcdef is the sha1 of the commit you want to apply)

You can do it this way inside a program:

#include <sys/resource.h>

// core dumps may be disallowed by parent of this process; change that
struct rlimit core_limits;
core_limits.rlim_cur = core_limits.rlim_max = RLIM_INFINITY;
setrlimit(RLIMIT_CORE, &core_limits);

Just cast one of the two operands to a float first.

v = (float)s / t;

The cast has higher precedence than the division, so happens before the division.

The other operand will be effectively automatically cast to a float by the compiler because the rules say that if either operand is of floating point type then the operation will be a floating point operation, even if the other operand is integral. Java Language Specification, §4.2.4 and §15.17

I'm using a BindingSource with a SqlDataReader behind it and none of the above works for me.

Question for Microsoft: Why does this work:

  ? lst.SelectedValue

But this doesn't?

   ? lst.Items[80].Value

I find I have to go back to to the BindingSource object, cast it as a System.Data.Common.DbDataRecord, and then refer to its column name:

   ? ((System.Data.Common.DbDataRecord)_bsBlocks[80])["BlockKey"]

Now that's just ridiculous.

To get the first n elements of an array, use

array.slice(0, n);

Try this:

SELECT Count(*)
FROM <DATABASE_NAME>.INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

Not CSS, but inline:

<a href="#" 
   onmouseover = "this.style.textDecoration = 'none'"
   onmouseout  = "this.style.textDecoration = 'underline'">Hello</a>

See example →

$myArr = array();

function someFuntion(array $myArr) {
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;

    return $myArr;
}

$myArr = someFunction($myArr);

My company does the same thing for a number of customers where we host a web site for them although in our case it's xyz.company.com rather than www.company.com. We do get them to set the A record on xyz.company.com to point to an IP address we allocate them.

As to how you could cope with a change in IP address I don't think there is a perfect solution. Some ideas are:

• Use a NAT or IP load balancer and give your customers an IP address belonging to it. If the IP address of the web server needs to change you could make an update on the NAT or load balancer,

• Offer a DNS hosting service as well and get your customers to host their domain with you so that you'd be in a position to update the A records,

• Get your customers to set their A record up to one main web server and use a HTTP redirect for each customer's web requests.

The accepted answer - git diff --name-only <notMainDev> $(git merge-base <notMainDev> <mainDev>) - is very close, but I noticed that it got the status wrong for deletions. I added a file in a branch, and yet this command (using --name-status) gave the file I deleted "A" status and the file I added "D" status.

I had to use this command instead:

git diff --name-only $(git merge-base <notMainDev> <mainDev>)

Easy recursive way

int    get_int_lenght(current_lenght, value)
{
 if (value / 10 < 10)
    return (current_lenght + 1);
return (get_int_lenght(current_lenght + 1, value))

I'd agree inheritance is a better fit for the problem posed.

I found this question really handy though on decorating classes, thanks all.

Here's another couple of examples, based on other answers, including how inheritance affects things in Python 2.7, (and @wraps, which maintains the original function's docstring, etc.):

def dec(klass):
    old_foo = klass.foo
    @wraps(klass.foo)
    def decorated_foo(self, *args ,**kwargs):
        print('@decorator pre %s' % msg)
        old_foo(self, *args, **kwargs)
        print('@decorator post %s' % msg)
    klass.foo = decorated_foo
    return klass

@dec  # No parentheses
class Foo...

Often you want to add parameters to your decorator:

from functools import wraps

def dec(msg='default'):
    def decorator(klass):
        old_foo = klass.foo
        @wraps(klass.foo)
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass
    return decorator

@dec('foo decorator')  # You must add parentheses now, even if they're empty
class Foo(object):
    def foo(self, *args, **kwargs):
        print('foo.foo()')

@dec('subfoo decorator')
class SubFoo(Foo):
    def foo(self, *args, **kwargs):
        print('subfoo.foo() pre')
        super(SubFoo, self).foo(*args, **kwargs)
        print('subfoo.foo() post')

@dec('subsubfoo decorator')
class SubSubFoo(SubFoo):
    def foo(self, *args, **kwargs):
        print('subsubfoo.foo() pre')
        super(SubSubFoo, self).foo(*args, **kwargs)
        print('subsubfoo.foo() post')

SubSubFoo().foo()

Outputs:

@decorator pre subsubfoo decorator
subsubfoo.foo() pre
@decorator pre subfoo decorator
subfoo.foo() pre
@decorator pre foo decorator
foo.foo()
@decorator post foo decorator
subfoo.foo() post
@decorator post subfoo decorator
subsubfoo.foo() post
@decorator post subsubfoo decorator

I've used a function decorator, as I find them more concise. Here's a class to decorate a class:

class Dec(object):

    def __init__(self, msg):
        self.msg = msg

    def __call__(self, klass):
        old_foo = klass.foo
        msg = self.msg
        def decorated_foo(self, *args, **kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass

A more robust version that checks for those parentheses, and works if the methods don't exist on the decorated class:

from inspect import isclass

def decorate_if(condition, decorator):
    return decorator if condition else lambda x: x

def dec(msg):
    # Only use if your decorator's first parameter is never a class
    assert not isclass(msg)

    def decorator(klass):
        old_foo = getattr(klass, 'foo', None)

        @decorate_if(old_foo, wraps(klass.foo))
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            if callable(old_foo):
                old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)

        klass.foo = decorated_foo
        return klass

    return decorator

The assert checks that the decorator has not been used without parentheses. If it has, then the class being decorated is passed to the msg parameter of the decorator, which raises an AssertionError.

@decorate_if only applies the decorator if condition evaluates to True.

The getattr, callable test, and @decorate_if are used so that the decorator doesn't break if the foo() method doesn't exist on the class being decorated.

So, I've done some work on family tree software. I think the problem you're trying to solve is that you need to be able to walk the tree without getting in infinite loops - in other words, the tree needs to be acyclical.

However, it looks like you're asserting that there is only one path between a person and one of their ancestors. That will guarantee that there are no cycles, but is too strict. Biologically speaking, descendancy is a directed acyclic graph (DAG). The case you have is certainly a degenerate case, but that type of thing happens all the time on larger trees.

For example, if you look at the 2^n ancestors you have at generation n, if there was no overlap, then you'd have more ancestors in 1000 AD than there were people alive. So, there's got to be overlap.

However, you also do tend to get cycles that are invalid, just bad data. If you're traversing the tree, then cycles must be dealt with. You can do this in each individual algorithm, or on load. I did it on load.

Finding true cycles in a tree can be done in a few ways. The wrong way is to mark every ancestor from a given individual, and when traversing, if the person you're going to step to next is already marked, then cut the link. This will sever potentially accurate relationships. The correct way to do it is to start from each individual, and mark each ancestor with the path to that individual. If the new path contains the current path as a subpath, then it's a cycle, and should be broken. You can store paths as vector<bool> (MFMF, MFFFMF, etc.) which makes the comparison and storage very fast.

There are a few other ways to detect cycles, such as sending out two iterators and seeing if they ever collide with the subset test, but I ended up using the local storage method.

Also note that you don't need to actually sever the link, you can just change it from a normal link to a 'weak' link, which isn't followed by some of your algorithms. You will also want to take care when choosing which link to mark as weak; sometimes you can figure out where the cycle should be broken by looking at birthdate information, but often you can't figure out anything because so much data is missing.

You are writing to memory you do not own:

int board[2][50]; //make an array with 3 columns  (wrong)
                  //(actually makes an array with only two 'columns')
...
for (i=0; i<num3+1; i++)
    board[2][i] = 'O';
          ^

Change this line:

int board[2][50]; //array with 2 columns (legal indices [0-1][0-49])
          ^

To:

int board[3][50]; //array with 3 columns (legal indices [0-2][0-49])
          ^

When creating an array, the value used to initialize: [3] indicates array size.
However, when accessing existing array elements, index values are zero based.

For an array created: int board[3][50];
Legal indices are board[0][0]...board[2][49]

EDIT To address bad output comment and initialization comment

add an additional "\n" for formatting output:

Change:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
 }

       ...

To:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
  printf("\n");//at the end of every row, print a new line
}
...  

Initialize board variable:

int board[3][50] = {0};//initialize all elements to zero

Try adding an extension like this:

    public extension UIDevice {

    var modelName: String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8 where value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }

        switch identifier {
        case "iPod5,1":                                 return "iPod Touch 5"

        }
    }

}

This is how you will use it:

let modelName = UIDevice.currentDevice().modelName

EDIT For simulator, you can try a solution here

You have a wrong idea of what fgets returns. Take a look at this: http://www.cplusplus.com/reference/clibrary/cstdio/fgets/

It returns null when it finds an EOF character. Try running the program above and pressing CTRL+D (or whatever combination is your EOF character), and the loop will exit succesfully.

How do you want to detect the end of the input? Newline? Dot (you said sentence xD)?

The CompileSdkVersion is the version of the SDK platform your app works with for compilation, etc DURING the development process (you should always use the latest) This is shipped with the API version you are using

You will see this in your build.gradle file:

targetSdkVersion: contains the info your app ships with AFTER the development process to the app store that allows it to TARGET the SPECIFIED version of the Android platform. Depending on the functionality of your app, it can target API versions lower than the current.For instance, you can target API 18 even if the current version is 23.

Take a good look at this official Google page.

[Ljava.lang.Object; is the name for Object[].class, the java.lang.Class representing the class of array of Object.

The naming scheme is documented in Class.getName():

If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).

If this class object represents a primitive type or void, then the name returned is the Java language keyword corresponding to the primitive type or void.

If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more '[' characters representing the depth of the array nesting. The encoding of element type names is as follows:

Element Type        Encoding
boolean             Z
byte                B
char                C
double              D
float               F
int                 I
long                J
short               S 
class or interface  Lclassname;

Yours is the last on that list. Here are some examples:

// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx

The reason why the toString() method on arrays returns String in this format is because arrays do not @Override the method inherited from Object, which is specified as follows:

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Note: you can not rely on the toString() of any arbitrary object to follow the above specification, since they can (and usually do) @Override it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass() on it (a final method inherited from Object) and then reflecting on the returned Class object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).

On a more "useful" toString for arrays

java.util.Arrays provides toString overloads for primitive arrays and Object[]. There is also deepToString that you may want to use for nested arrays.

Here are some examples:

int[] nums = { 1, 2, 3 };

System.out.println(nums);
// [I@xxxxx

System.out.println(Arrays.toString(nums));
// [1, 2, 3]

int[][] table = {
        { 1, },
        { 2, 3, },
        { 4, 5, 6, },
};

System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]

System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]

There are also Arrays.equals and Arrays.deepEquals that perform array equality comparison by their elements, among many other array-related utility methods.

Are you asking for renaming column itself or capitalise the data inside column? If its data you've to change, then use this:

UPDATE [yourtable]
SET word=UPPER(LEFT(word,1))+LOWER(SUBSTRING(word,2,LEN(word)))

If you just wanted to change it only for displaying and do not need the actual data in table to change:

SELECT UPPER(LEFT(word,1))+LOWER(SUBSTRING(word,2,LEN(word))) FROM [yourtable]

Hope this helps.

EDIT: I realised about the '-' so here is my attempt to solve this problem in a function.

CREATE FUNCTION [dbo].[CapitalizeFirstLetter]
(
--string need to format
@string VARCHAR(200)--increase the variable size depending on your needs.
)
RETURNS VARCHAR(200)
AS

BEGIN
--Declare Variables
DECLARE @Index INT,
@ResultString VARCHAR(200)--result string size should equal to the @string variable size
--Initialize the variables
SET @Index = 1
SET @ResultString = ''
--Run the Loop until END of the string

WHILE (@Index <LEN(@string)+1)
BEGIN
IF (@Index = 1)--first letter of the string
BEGIN
--make the first letter capital
SET @ResultString =
@ResultString + UPPER(SUBSTRING(@string, @Index, 1))
SET @Index = @Index+ 1--increase the index
END

-- IF the previous character is space or '-' or next character is '-'

ELSE IF ((SUBSTRING(@string, @Index-1, 1) =' 'or SUBSTRING(@string, @Index-1, 1) ='-' or SUBSTRING(@string, @Index+1, 1) ='-') and @Index+1 <> LEN(@string))
BEGIN
--make the letter capital
SET
@ResultString = @ResultString + UPPER(SUBSTRING(@string,@Index, 1))
SET
@Index = @Index +1--increase the index
END
ELSE-- all others
BEGIN
-- make the letter simple
SET
@ResultString = @ResultString + LOWER(SUBSTRING(@string,@Index, 1))
SET
@Index = @Index +1--incerase the index
END
END--END of the loop

IF (@@ERROR
<> 0)-- any error occur return the sEND string
BEGIN
SET
@ResultString = @string
END
-- IF no error found return the new string
RETURN @ResultString
END

So then the code would be:

UPDATE [yourtable]
SET word=dbo.CapitalizeFirstLetter([STRING TO GO HERE])

For mac OS you should use this :

body {
 background: url(../../img/bg.png);
}

$(document).on("keypress", ".classname", function(evt) {
    evt = (evt) ? evt : window.event;
    var charCode = (evt.which) ? evt.which : evt.keyCode;
    if (charCode > 31 && (charCode < 48 || charCode > 57)) {
        return false;
    }
    return true;
});

I actually had an issue where my db was pretty much locked by the processes and a race condition with them, by the time I got one command executed refreshed and they had it locked again... I had to run the following commands back to back in SSMS and got me offline and from there I did my restore and came back online just fine, the two queries where:

First ran:

USE master
GO

DECLARE @kill varchar(8000) = '';
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';'
FROM master..sysprocesses 
WHERE dbid = db_id('<yourDbName>')

EXEC(@kill);

Then immediately after (in second query window):

USE master ALTER DATABASE <yourDbName> SET OFFLINE WITH ROLLBACK IMMEDIATE

Did what I needed and then brought it back online. Thanks to all who wrote these pieces out for me to combine and solve my problem.

You can try this code into your activity

    private void startWebView(WebView webView,String url) {
 webView.setWebViewClient(new WebViewClient() {
            ProgressDialog progressDialog;

            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return false;
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
            }

            public void onLoadResource (WebView view, String url) {

                    if (progressDialog == null) {
                        progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
                        progressDialog.setMessage("Loading...");
                        progressDialog.show();
                    }

            }
            public void onPageFinished(WebView view, String url) {
                try{
                    if (progressDialog.isShowing()) {
                        progressDialog.dismiss();
                        progressDialog = null;
                    }

                }catch(Exception exception){
                    exception.printStackTrace();
                }
            }

        });

        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl(url);
    }

Call this method using this way:

startWebView(web_view,"Your Url");

Sometimes if URL is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason progress bar will not dismis. To solve this issue see my this Answer.

Thanks :)

select count(*) from 
(
SELECT distinct column1,column2,column3,column4 FROM abcd

This will give count of distinct group of columns.

On your user model just add a 'hasRole' method like below

public boolean hasRole(String auth) {
    for (Role role : roles) {
        if (role.getName().equals(auth)) { return true; }
    }
    return false;
}

I usually use it to check if the authenticated user has the role admin as follows

Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); // This gets the authentication
User authUser = (User) authentication.getPrincipal(); // This gets the logged in user
authUser.hasRole("ROLE_ADMIN") // This returns true or false

All the calls to UI should be asynchronous, anything you change on the UI like updating table or changing text label should be done from main thread. using DispatchQueue.main will add your operation to the queue on the main thread.

Swift 4

DispatchQueue.main.async{
    self.tableView.reloadData()
}

I'd use iloc, which takes a row/column slice, both based on integer position and following normal python syntax. If you want every 5th row:

df.iloc[::5, :]

Just using special Closure

// declare and implement:
def eachWithBreak = { list, Closure c ->
  boolean bBreak = false
  list.each() { it ->
     if (bBreak) return
     bBreak = c(it)
  }
}

def list = [1,2,3,4,5,6]
eachWithBreak list, { it ->
  if (it > 3) return true // break 'eachWithBreak'
  println it
  return false // next it
}

In my case it was caused by the absence of the jackson-core, jackson-annotations and jackson-databind jars from the runtime classpath. It did not complain with the usual ClassNothFoundException as one would expect but rather with the error mentioned in the original question.

Failed to delete C:\EclipseProjects\myGoogleAppEngine\target\myGoogleAppEngine-0.0.1-SNAPSHOT\WEB-INF\lib\spring-webmvc-3.1.0.RELEASE.jar

Because of the path C:\EclipseProjects i guess you have eclipse running on that project. If you application runs, you cannot clean the output, because it may be in use.

Stop the application and maybe eclipse and try again.

I used the a similar approach as @iod07, but as an extension. Also, I added some explanations in the comments to understand how it works.

Basically, just add this at the top or bottom of your view controller.

extension NSString {

class func convertFormatOfDate(date: String, originalFormat: String, destinationFormat: String) -> String! {

    // Orginal format :
    let dateOriginalFormat = NSDateFormatter()
    dateOriginalFormat.dateFormat = originalFormat      // in the example it'll take "yy MM dd" (from our call)

    // Destination format :
    let dateDestinationFormat = NSDateFormatter()
    dateDestinationFormat.dateFormat = destinationFormat // in the example it'll take "EEEE dd MMMM yyyy" (from our call)

    // Convert current String Date to NSDate
    let dateFromString = dateOriginalFormat.dateFromString(date)

    // Convert new NSDate created above to String with the good format
    let dateFormated = dateDestinationFormat.stringFromDate(dateFromString!)

    return dateFormated

}
}

Example

Let's say you want to convert "16 05 05" to "Thursday 05 May 2016" and your date is declared as follow let date = "16 06 05"

Then simply call call it with :

let newDate = NSString.convertFormatOfDate(date, originalFormat: "yy MM dd", destinationFormat: "EEEE dd MMMM yyyy")

Hope it helps !

.then function of promiseB receives what is returned from .then function of promiseA.

here promiseA is returning is a number, which will be available as number parameter in success function of promiseB. which will then be incremented by 1

You can do it. That is what big guys do as well.

As you see, the list of IPs rotated around, but the relative order between two IPs stayed the same.

Update: I see several comments bragging about how DNS round-robin is not convenient for fail-over, so here is the summary: DNS is not for fail-over. So it is obviously not good for fail-over. It was never designed to be a solution for fail-over.

The regular expression you was looking for is: /^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#\$%\^&\*\[\]"\';:_\-<>\., =\+\/\\]).{8,}$/u.

Angular hasn't provided a way to signal when a page finished loading, maybe because "finished" depends on your application. For example, if you have hierarchical tree of partials, one loading the others. "Finish" would mean that all of them have been loaded. Any framework would have a hard time analyzing your code and understanding that everything is done, or still waited upon. For that, you would have to provide application-specific logic to check and determine that.

It's working

Try below code

$('#example').dataTable({
    "bProcessing": true,
    "sAutoWidth": false,
    "bDestroy":true,
    "sPaginationType": "bootstrap", // full_numbers
    "iDisplayStart ": 10,
    "iDisplayLength": 10,
    "bPaginate": false, //hide pagination
    "bFilter": false, //hide Search bar
    "bInfo": false, // hide showing entries
})

You can use regular expression like this.

/^[(]+\ ++\d{2}[)]+[^0]+\d{9}/

Use this for GET values:

Request.QueryString["key"]

And this for POST values

Request.Form["key"]

Also, this will work if you don't care whether it comes from GET or POST, or the HttpContext.Items collection:

Request["key"]

Another thing to note (if you need it) is you can check the type of request by using:

Request.RequestType

Which will be the verb used to access the page (usually GET or POST). Request.IsPostBack will usually work to check this, but only if the POST request includes the hidden fields added to the page by the ASP.NET framework.

Others have pointed out the deleteCharAt method, but here's another alternative approach:

String prefix = "";
for (String serverId : serverIds) {
  sb.append(prefix);
  prefix = ",";
  sb.append(serverId);
}

Alternatively, use the Joiner class from Guava :)

As of Java 8, StringJoiner is part of the standard JRE.

Yes -- for long double, you need to use %Lf (i.e., upper-case 'L').

A quick performance test showing Lutz's solution is the best:

import time

def speed_test(func):
    def wrapper(*args, **kwargs):
        t1 = time.time()
        for x in xrange(5000):
            results = func(*args, **kwargs)
        t2 = time.time()
        print '%s took %0.3f ms' % (func.func_name, (t2-t1)*1000.0)
        return results
    return wrapper

@speed_test
def compare_bitwise(x, y):
    set_x = frozenset(x)
    set_y = frozenset(y)
    return set_x & set_y

@speed_test
def compare_listcomp(x, y):
    return [i for i, j in zip(x, y) if i == j]

@speed_test
def compare_intersect(x, y):
    return frozenset(x).intersection(y)

# Comparing short lists
a = [1, 2, 3, 4, 5]
b = [9, 8, 7, 6, 5]
compare_bitwise(a, b)
compare_listcomp(a, b)
compare_intersect(a, b)

# Comparing longer lists
import random
a = random.sample(xrange(100000), 10000)
b = random.sample(xrange(100000), 10000)
compare_bitwise(a, b)
compare_listcomp(a, b)
compare_intersect(a, b)

These are the results on my machine:

# Short list:
compare_bitwise took 10.145 ms
compare_listcomp took 11.157 ms
compare_intersect took 7.461 ms

# Long list:
compare_bitwise took 11203.709 ms
compare_listcomp took 17361.736 ms
compare_intersect took 6833.768 ms

Obviously, any artificial performance test should be taken with a grain of salt, but since the set().intersection() answer is at least as fast as the other solutions, and also the most readable, it should be the standard solution for this common problem.

GNU linker, in my case companion of GCC 8.1.0, well detects not re-declared pure virtual methods, but above certain complexity of class design it fails to identify missing implementation of methods and answers with a flat "V-Table Missing",

or even tends to report missing implementation, in spite it is there.

The only solution then is to verify consistency of declaration of implementation manually, method by method.

Since some of the functions depend on other libraries like GEOS and proj4 you might want to get their versions too. Then use:

SELECT PostGIS_full_version();

You can also do this with named ranges so you don't have to copy the cells from Sheet1 to Sheet2:

1. Define a named range, say Sheet1Vals for the column that has the values on which you want to base your condition. You can define a new named range by using the Insert\Name\Define... menu item. Type in your name, then use the cell browser in the Refers to box to select the cells you want in the range. If the range will change over time (add or remove rows) you can use this formula instead of selecting the cells explicitly:

   =OFFSET('SheetName'!$COL$ROW,0,0,COUNTA('SheetName'!$COL:$COL)).

   Add a -1 before the last ) if the column has a header row.

2. Define a named range, say Sheet2Vals for the column that has the values you want to conditionally format.

3. Use the Conditional Formatting dialog to create your conditions. Specify Formula Is in the dropdown, then put this for the formula:

   =INDEX(Sheet1Vals, MATCH([FirstCellInRange],Sheet2Vals))=[Condition]

   where [FirstCellInRange] is the address of the cell you want to format and [Condition] is the value your checking.

For example, if my conditions in Sheet1 have the values of 1, 2 and 3 and the column I'm formatting is column B in Sheet2 then my conditional formats would be something like:

=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=1
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=2
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=3

You can then use the format painter to copy these formats to the rest of the cells.

Call the global process object's exit method:

process.exit()

From the docs:

process.exit([exitcode])

Ends the process with the specified code. If omitted, exit uses the 'success' code 0.

To exit with a 'failure' code:

process.exit(1);

The shell that executed node should see the exit code as 1.

Thank you OP for your question, and Roman for your answer. I had to search a bit to find this; I hope the following helps others.

dtypes. Difference between S1 and S2 in Python

"The |S1 and |S2 strings are data type descriptors; the first means the array holds strings of length 1, the second of length 2. ..."

what they mean is no, you can't. there is no way to get it done. so it was possible you could do something like this

function create(obj, const){
// where obj is an object and const is a variable name
function const () {}

const.prototype.myProperty = property_value;
// .. more prototype

return new const();

}

having a create function just like the one implemented in ECMAScript 5.

In my case, I had to change the cell padding of an element that contained an input checkbox for a table that's being dynamically rendered with DataTables:

<td class="dt-center">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

After implementing the following line code within the initComplete function I was able to produce the correct padding, which fixed the rows from being displayed with an abnormally large height

 $('tbody td:has(input.a)').css('padding', '0px');

Now, you can see that the correct styles are being applied to the parent element:

<td class=" dt-center" style="padding: 0px;">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

Essentially, this answer is an extension of @KP's answer, but the more collaboration of implementing this the better. In summation, I hope this helps someone else because it works! Lastly, thank you so much @KP for leading me in the right direction!

The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr) instead of 1fr as your track size.

Use a LEFT JOIN checking the right side for nulls.

SELECT a.Id
FROM TableA a
LEFT JOIN TableB on a.Id = b.Id
WHERE b.Id IS NULL

The above would match up TableA and TableB based on the Id column in each, and then give you the rows where the B side is empty.

rng.step(n=1) {| obj | block } => rng

Iterates over rng, passing each nth element to the block. If the range contains numbers or strings, natural ordering is used. Otherwise step invokes succ to iterate through range elements. The following code uses class Xs, which is defined in the class-level documentation.

range = Xs.new(1)..Xs.new(10)
range.step(2) {|x| puts x}
range.step(3) {|x| puts x}

produces:

1 x
3 xxx
5 xxxxx
7 xxxxxxx
9 xxxxxxxxx
1 x
4 xxxx
7 xxxxxxx
10 xxxxxxxxxx

I think this example explains clearly the differences between inheritance and composition.

In this exmple, the problem is solved using inheritance and composition. The author pays attention to the fact that ; in inheritance, a change in superclass might cause problems in derived class, that inherit it.

There you can also see the difference in representation when you use a UML for inheritance or composition.

A similar question was asked about doing this on an ASP page (link) and the consensus over there was that it was not possible to do with recaptcha. It seems that multiple forms on a single page must share the captcha, unless you're willing to use a different captcha. If you are not locked into recaptcha a good library to take a look at is the Zend Frameworks Zend_Captcha component (link). It contains a few

1. first you can do with this style:

   mda="/usr/mda"
   if [ ! -L "${mda}" ]; then
     echo "=> File doesn't exist"
   fi
   

2. if you want to do it in more advanced style you can write it like below:

   #!/bin/bash
   mda="$1"
   if [ -e "$1" ]; then
       if [ ! -L "$1" ]
       then
           echo "you entry is not symlink"
       else
           echo "your entry is symlink"
       fi
   else
     echo "=> File doesn't exist"
   fi
   

the result of above is like:

root@linux:~# ./sym.sh /etc/passwd
you entry is not symlink
root@linux:~# ./sym.sh /usr/mda 
your entry is symlink
root@linux:~# ./sym.sh 
=> File doesn't exist

Pike's notion of "concurrency" is an intentional design and implementation decision. A concurrent-capable program design may or may not exhibit behavioral "parallelism"; it depends upon the runtime environment.

You don't want parallelism exhibited by a program that wasn't designed for concurrency. :-) But to the extent that it's a net gain for the relevant factors (power consumption, performance, etc.), you want a maximally-concurrent design so that the host system can parallelize its execution when possible.

Pike's Go programming language illustrates this in the extreme: his functions are all threads that can run correctly concurrently, i.e. calling a function always creates a thread that will run in parallel with the caller if the system is capable of it. An application with hundreds or even thousands of threads is perfectly ordinary in his world. (I'm no Go expert, that's just my take on it.)

The repo command can't care what kind of quotes it gets. If you need parameter expansion, use double quotes. If that means you wind up having to backslash a lot of stuff, use single quotes for most of it, and then break out of them and go into doubles for the part where you need the expansion to happen.

repo forall -c 'literal stuff goes here; '"stuff with $parameters here"' more literal stuff'

Explanation follows, if you're interested.

When you run a command from the shell, what that command receives as arguments is an array of null-terminated strings. Those strings may contain absolutely any non-null character.

But when the shell is building that array of strings from a command line, it interprets some characters specially; this is designed to make commands easier (indeed, possible) to type. For instance, spaces normally indicate the boundary between strings in the array; for that reason, the individual arguments are sometimes called "words". But an argument may nonetheless have spaces in it; you just need some way to tell the shell that's what you want.

You can use a backslash in front of any character (including space, or another backslash) to tell the shell to treat that character literally. But while you can do something like this:

echo \”That\'ll\ be\ \$4.96,\ please,\"\ said\ the\ cashier

...it can get tiresome. So the shell offers an alternative: quotation marks. These come in two main varieties.

Double-quotation marks are called "grouping quotes". They prevent wildcards and aliases from being expanded, but mostly they're for including spaces in a word. Other things like parameter and command expansion (the sorts of thing signaled by a $) still happen. And of course if you want a literal double-quote inside double-quotes, you have to backslash it:

echo "\"That'll be \$4.96, please,\" said the cashier"

Single-quotation marks are more draconian. Everything between them is taken completely literally, including backslashes. There is absolutely no way to get a literal single quote inside single quotes.

Fortunately, quotation marks in the shell are not word delimiters; by themselves, they don't terminate a word. You can go in and out of quotes, including between different types of quotes, within the same word to get the desired result:

echo '"That'\''ll be $4.96, please," said the cashier'

So that's easier - a lot fewer backslashes, although the close-single-quote, backslashed-literal-single-quote, open-single-quote sequence takes some getting used to.

Modern shells have added another quoting style not specified by the POSIX standard, in which the leading single quotation mark is prefixed with a dollar sign. Strings so quoted follow similar conventions to string literals in the ANSI standard version of the C programming language, and are therefore sometimes called "ANSI strings" and the $'...' pair "ANSI quotes". Within such strings, the above advice about backslashes being taken literally no longer applies. Instead, they become special again - not only can you include a literal single quotation mark or backslash by prepending a backslash to it, but the shell also expands the ANSI C character escapes (like \n for a newline, \t for tab, and \xHH for the character with hexadecimal code HH). Otherwise, however, they behave as single-quoted strings: no parameter or command substitution takes place:

echo $'"That\'ll be $4.96, please," said the cashier'

The important thing to note is that the single string received as the argument to the echo command is exactly the same in all of these examples. After the shell is done parsing a command line, there is no way for the command being run to tell what was quoted how. Even if it wanted to.

I prefer joda for date and time arithmetics because it is much better readable:

Date tomorrow = now().plusDays(1).toDate();

Or

endOfDay(now().plus(days(1))).toDate()
startOfDay(now().plus(days(1))).toDate()

Here's an example of code which uses the UTL_FILE.PUT and UTL_FILE.PUT_LINE calls:

declare 
  fHandle  UTL_FILE.FILE_TYPE;
begin
  fHandle := UTL_FILE.FOPEN('my_directory', 'test_file', 'w');

  UTL_FILE.PUT(fHandle, 'This is the first line');
  UTL_FILE.PUT(fHandle, 'This is the second line');
  UTL_FILE.PUT_LINE(fHandle, 'This is the third line');

  UTL_FILE.FCLOSE(fHandle);
EXCEPTION
  WHEN OTHERS THEN
    DBMS_OUTPUT.PUT_LINE('Exception: SQLCODE=' || SQLCODE || '  SQLERRM=' || SQLERRM);
    RAISE;
end;

The output from this looks like:

This is the first lineThis is the second lineThis is the third line

Share and enjoy.

I have found that this works quite well

if(col1/col1= 1,'number',col1) AS myInfo

I know that it could be done with a FOR but I wanted to know if there's another way

There is another way. You can also do it with map and itemgetter:

>>> from operator import itemgetter
>>> map(itemgetter(1), elements)

This still performs a loop internally though and it is slightly slower than the list comprehension:

setup = 'elements = [(1,1,1) for _ in range(100000)];from operator import itemgetter'
method1 = '[x[1] for x in elements]'
method2 = 'map(itemgetter(1), elements)'

import timeit
t = timeit.Timer(method1, setup)
print('Method 1: ' + str(t.timeit(100)))
t = timeit.Timer(method2, setup)
print('Method 2: ' + str(t.timeit(100)))

Results:

Method 1: 1.25699996948
Method 2: 1.46600008011

If you need to iterate over a list then using a for is fine.

Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.

What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?

You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.

I suggest Pdfkit. (installation guide)

It creates pdf from html files. I chose it to create pdf in 2 steps from my Python Pyramid stack:

1. Rendering server-side with mako templates with the style and markup you want for you pdf document
2. Executing pdfkit.from_string(...) method by passing the rendered html as parameter

This way you get a pdf document with styling and images supported.

You can install it as follows :

• using pip

  pip install pdfkit

• You will also need to install wkhtmltopdf (on Ubuntu).

According to HTML living standard specification, the load event is

Fired at the Window when the document has finished loading; fired at an element containing a resource (e.g. img, embed) when its resource has finished loading

I.e. load event is not fired on document object.

The suggested answer no longer works after 2014. Now you have to use Google Maps Embed API for loading into iframe.

Here is the link for the question and solution.

If you are using Angular like me you won't be able to load the google maps in iframe because of XSS security issue. For that you need to sanitise the URL with Pipe from angular.

Here is the link to do so.

All the suggestions are tested and works 100% as of today.

{{#each array}}
  {{@index}}
{{/each}}

A single pipe (|) is the bitwise OR operator.

Two pipes (||) is the logical OR operator.

They are not interchangeable.
