Programs & Examples On #Badimageformatexception

For running it on any CPU either 62 bit or 32 bit follow these steps: Right click on the name of the project in Solution Explorer> Properties>Build and have these under Configuration: Active(Release), Platform:Active(Any CPU) and Target:x86. and just beside the Run button Select option Release and Any CPU from the options. And then Save it and Run.

If you use LibreOffice from your program via cli .net integration like me, I got the same error. I use the older version of LibreOffice on the production environment on my PC I installed a newer version that was in conflict. Just uninstall LibreOffice. I found the solution here .NET CLI: Could not load file or assembly 'cli_cppuhelper'

In my case, I was using InstallUtil.exe which was causing an error. To install the .Net Core service in window best way to use sc command.

More information here Exe installation throwing error The module was expected to contain an assembly manifest .Net Core

In my case, I was running tests through MSTest and found out that I was deploying both a 32-bit and 64-bit DLL to the test directory. The program was favoring the 64-bit DLL and causing it to fail.

TL;DR Make sure you only deploy 32-bit DLLs to tests.

1. vim filename
2. press /
3. type word which you want to search
4. press Enter

This is just a possible scenario which happened to me. Well if it helps someone then great: I wrote a complicated app which somewhere along the code I used a function to clear all textboxes values before showing them. Sometime later I tried to set a textbox value using jquery val('value') but I did'nt notice that right after that I invoked the ClearAllInputs method.. so, this could also happen.

As you probably know, the maximum request length is configured in TWO places.

1. maxRequestLength - controlled at the ASP.NET app level
2. maxAllowedContentLength - under <system.webServer>, controlled at the IIS level

The first case is covered by other answers to this question.

To catch THE SECOND ONE you need to do this in global.asax:

protected void Application_EndRequest(object sender, EventArgs e)
{
    //check for the "file is too big" exception if thrown at the IIS level
    if (Response.StatusCode == 404 && Response.SubStatusCode == 13)
    {
        Response.Write("Too big a file"); //just an example
        Response.End();
    }
}

Summarizing

Oracle:

ALTER TABLE table_name DROP (column_name1, column_name2);

MS SQL Server:

ALTER TABLE table_name DROP COLUMN column_name1, column_name2

MySQL:

ALTER TABLE table_name DROP column_name1, DROP column_name2;

PostgreSQL

ALTER TABLE table_name DROP COLUMN column_name1, DROP COLUMN column_name2;

Be aware

DROP COLUMN does not physically remove the data for some DBMS. E.g. for MS SQL. For fixed length types (int, numeric, float, datetime, uniqueidentifier etc) the space is consumed even for records added after the columns were dropped. To get rid of the wasted space do ALTER TABLE ... REBUILD.

This is caused by editing file in windows and importing and executing in unix.

dos2unix -k -o filename should do the trick.

Your C# action "Save" doesn't execute because your AJAX url is pointing to "/Home/SaveDetailedInfo" and not "/Home/Save".

To call another action from within an action you can maybe try this solution: link

Here's another better solution : link

[HttpPost]
public ActionResult SaveDetailedInfo(Option[] Options)
{
    return Json(new { status = "Success", message = "Success" });
}

[HttpPost]
public ActionResult Save()
{ 
    return RedirectToAction("SaveDetailedInfo", Options);
}

AJAX:

Initial ajax call url: "/Home/Save"
on success callback: 
   make new ajax url: "/Home/SaveDetailedInfo"

You can run chrome with the --unsafely-treat-insecure-origin-as-secure="http://example.com" flag (replacing "example.com" with the origin you actually want to test), which will treat that origin as secure for this session. Note that you also need to include the --user-data-dir=/test/only/profile/dir to create a fresh testing profile for the flag to work.

For example if use Windows, Click Start and run.

chrome --unsafely-treat-insecure-origin-as-secure="http://localhost:8100"  --user-data-dir=C:\testprofile

You can use the querySelector for that:

document.querySelector('[id^="poll-"]').id;

The selector means: get an element where the attribute [id] begins with the string "poll-".

^ matches the start
* matches any position
$ matches the end

jsfiddle

How about this:

    string test = "01-12-12";
    try{
         DateTime dateTime = DateTime.Parse(test);
         test = dateTime.ToString("dd/yyyy");
    }
    catch (FormatException exc)
    {
        MessageBox.Show(exc.Message);
    }

Where test will be equal to "12/2012"

Hope it helps!

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

The problem is that t.join() blocks the click event, the main thread does not get back to the event loop to process repaints. See Why ttk Progressbar appears after process in Tkinter or TTK progress bar blocked when sending email

In addition, you can use it to check if the dynamic allocation was successful.

Code example:

int ** p;
p = new int * [5];      // Dynamic array (size 5) of pointers to int
for (int i = 0; i < 5; ++i) {
    p[i] = new int[3]; // Each i(ptr) is now pointing to a dynamic
                       // array (size 3) of actual int values
}

assert (p);            // Check the dynamic allocation.

Similar to:

if (p == NULL) {
    cout << "dynamic allocation failed" << endl;
    exit(1);
}

Try with this code:

class WatchPlotDirectory
{
    bool let = false;
    FileSystemWatcher watcher;
    string path = "C:/Users/jamie/OneDrive/Pictures/Screenshots";

    public WatchPlotDirectory()
    {
        watcher = new FileSystemWatcher();
        watcher.Path = path;
        watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
                               | NotifyFilters.FileName | NotifyFilters.DirectoryName;
        watcher.Filter = "*.*";
        watcher.Changed += new FileSystemEventHandler(OnChanged);
        watcher.Renamed += new RenamedEventHandler(OnRenamed);
        watcher.EnableRaisingEvents = true;
    }



    void OnChanged(object sender, FileSystemEventArgs e)
    {
        if (let==false) {
            string mgs = string.Format("File {0} | {1}",
                                       e.FullPath, e.ChangeType);
            Console.WriteLine("onchange: " + mgs);
            let = true;
        }

        else
        {
            let = false;
        }


    }

    void OnRenamed(object sender, RenamedEventArgs e)
    {
        string log = string.Format("{0} | Renamed from {1}",
                                   e.FullPath, e.OldName);
        Console.WriteLine("onrenamed: " + log);

    }

    public void setPath(string path)
    {
        this.path = path;
    }
}

You need to check both $mysqli and $statement. If they are false, you need to output $mysqli->error or $statement->error respectively.

Efficiency

For simple scripts that may terminate, I use simple one-liners that trigger a PHP error with the message. For a more complex application, an error warning system should be activated instead, for example by throwing an exception.

Usage example 1: Simple script

# This is in a simple command line script
$mysqli = new mysqli('localhost', 'buzUser', 'buzPassword');
$q = "UPDATE foo SET bar=1";
($statement = $mysqli->prepare($q)) or trigger_error($mysqli->error, E_USER_ERROR);
$statement->execute() or trigger_error($statement->error, E_USER_ERROR);

Usage example 2: Application

# This is part of an application
class FuzDatabaseException extends Exception {
}

class Foo {
  public $mysqli;
  public function __construct(mysqli $mysqli) {
    $this->mysqli = $mysqli;
  }
  public function updateBar() {
    $q = "UPDATE foo SET bar=1";
    $statement = $this->mysqli->prepare($q);
    if (!$statement) {
      throw new FuzDatabaseException($mysqli->error);
    }

    if (!$statement->execute()) {
      throw new FuzDatabaseException($statement->error);
    }
  }
}

$foo = new Foo(new mysqli('localhost','buzUser','buzPassword'));
try {
  $foo->updateBar();
} catch (FuzDatabaseException $e)
  $msg = $e->getMessage();
  // Now send warning emails, write log
}

when you use \\b(\\w+)+\\b that means exact match with a word containing only word characters ([a-zA-Z0-9])

in your case for example setting \\b at the begining of regex will accept -12(with space) but again it won't accept -12(without space)

for reference to support my words: https://docs.oracle.com/javase/tutorial/essential/regex/bounds.html

For the text after the first = and before the next =

cut -d "=" -f2 <<< "$your_str"

or

sed -e 's#.*=\(\)#\1#' <<< "$your_str"

For all text after the first = regardless of if there are multiple =

cut -d "=" -f2- <<< "$your_str"

Got same error, solved changing target platform from "Mixed Platforms" to "Any CPU"

It means that if x is set, the value for z will be x, otherwise if y is set then its value will be set as the z's value.

it's the same as

if(x)
  z = x;
else
  z = y;

It's possible because logical operators in JavaScript doesn't return boolean values but the value of the last element needed to complete the operation (in an OR sentence it would be the first non-false value, in an AND sentence it would be the last one). If the operation fails, then false is returned.

I assume you don't want leading/trailing space. This means you have to split the regex into "first character", "stuff in the middle" and "last character":

^[a-zA-Z0-9_][a-zA-Z0-9_ ]*[a-zA-Z0-9_]$

or if you use a perl-like syntax:

^\w[\w ]*\w$

Also: If you intentionally worded your regex that it also allows empty Strings, you have to make the entire thing optional:

^(\w[\w ]*\w)?$

If you want to only allow single space chars, it looks a bit different:

^((\w+ )*\w+)?$

This matches 0..n words followed by a single space, plus one word without space. And makes the entire thing optional to allow empty strings.

You must use OverridePendingTransition method to achieve it, which is in the Activity class. Sample Animations in the apidemos example's res/anim folder. Check it. More than check the demo in ApiDemos/App/Activity/animation.

Example:

@Override
public void onResume(){
    // TODO LC: preliminary support for views transitions
    this.overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
}

My Solution to this problem is

<li class="@(Context.Request.Path.Value.ToLower().Contains("about") ? "active " : "" ) nav-item">
                <a class="nav-link" asp-area="" asp-controller="Home" asp-action="About">About</a>
            </li>

A better way may be adding an Html extension method to return the current path to be compared with link

Use System.currentTimeMillis() or System.nanoTime() if you want even more precise reading. Usually, milliseconds is precise enough if you need to output the value to the user. Moreover, System.nanoTime() may return negative values, thus it may be possible that, if you're using that method, the return value is not correct.

A general and wide use would be to use milliseconds :

long start = System.currentTimeMillis();

... 


long end = System.currentTimeMillis();

NumberFormat formatter = new DecimalFormat("#0.00000");
System.out.print("Execution time is " + formatter.format((end - start) / 1000d) + " seconds");

Note that nanoseconds are usually used to calculate very short and precise program executions, such as unit testing and benchmarking. Thus, for overall program execution, milliseconds are preferable.

x='buffalo'    
exec("%s = %d" % (x,2))

After that you can check it by:

print buffalo

As an output you will see: 2

Try this:

select songName from t
where personName in ('Ryan', 'Holly')
group by songName
having count(distinct personName) = 2

The number in the having should match the amount of people. If you also need the Status to be Complete use this where clause instead of the previous one:

where personName in ('Ryan', 'Holly') and status = 'Complete'

I use the following script for repairing malformed sqlite files:

#!/bin/bash

cat <( sqlite3 "$1" .dump | grep "^ROLLBACK" -v ) <( echo "COMMIT;" ) | sqlite3 "fix_$1"

Most of the time when a sqlite database is malformed it is still possible to make a dump. This dump is basically a lot of SQL statements that rebuild the database.

Some rows might be missing from the dump (probably becasue they are corrupted). If this is the case the INSERT statements of the missing rows will be replaced with some comments and the script will end with a ROLLBACK TRANSACTION.

So what we do here is we make the dump (malformed rows are excluded) and we replace the ROLLBACK with a COMMIT so that the entire dump script will be committed in stead of rolled back.

This method saved my life a couple of 100 times already \o/

According to the documentation of Spring-Cloud-Config there is one extra scope next to the existing five. It is @RefreshScope.

This is the short description of RefreshScope:

When there is a configuration change, a Spring @Bean that is marked as @RefreshScope gets special treatment. This feature addresses the problem of stateful beans that only get their configuration injected when they are initialized. For instance, if a DataSource has open connections when the database URL is changed via the Environment, you probably want the holders of those connections to be able to complete what they are doing. Then, the next time something borrows a connection from the pool, it gets one with the new URL.

Sometimes, it might even be mandatory to apply the @RefreshScope annotation on some beans which can be only initialized once. If a bean is "immutable", you will have to either annotate the bean with @RefreshScope or specify the classname under the property key spring.cloud.refresh.extra-refreshable.

Refresh scope beans are lazy proxies that initialize when they are used (that is, when a method is called), and the scope acts as a cache of initialized values. To force a bean to re-initialize on the next method call, you must invalidate its cache entry.

The RefreshScope is a bean in the context and has a public refreshAll() method to refresh all beans in the scope by clearing the target cache. The /refresh endpoint exposes this functionality (over HTTP or JMX). To refresh an individual bean by name, there is also a refresh(String) method.

To complete the answer from Sotorios Delimanolis.

It's true that ResponseEntity gives you more flexibility but in most cases you won't need it and you'll end up with these ResponseEntity everywhere in your controller thus making it difficult to read and understand.

If you want to handle special cases like errors (Not Found, Conflict, etc.), you can add a HandlerExceptionResolver to your Spring configuration. So in your code, you just throw a specific exception (NotFoundException for instance) and decide what to do in your Handler (setting the HTTP status to 404), making the Controller code more clear.

Reading the file

import scipy.io
mat = scipy.io.loadmat(file_name)

Inspecting the type of MAT variable

print(type(mat))
#OUTPUT - <class 'dict'>

The keys inside the dictionary are MATLAB variables, and the values are the objects assigned to those variables.

this will work just fine ... and its recursive

File root = new File("ROOT PATH");
for ( File file : root.listFiles())
{
    getFilesRecursive(file);
}


private static void getFilesRecursive(File pFile)
{
    for(File files : pFile.listFiles())
    {
        if(files.isDirectory())
        {
            getFilesRecursive(files);
        }
        else
        {
            // do your thing 
            // you can either save in HashMap and use it as
            // per your requirement
        }
    }
}

I think that if your "item_manuf_id" is the primary key of the DataTable you could use the Find method ...

string s = "stringValue";
DataRow foundRow = dtPs.Rows.Find(s);
if(foundRow != null) {
 //You have it ...
 }

There are many ways certainly, but in my case I prefer the dump and diff command. So here is an script based on Jared's comment:

#!/bin/sh

echo "Usage: dbdiff [user1:pass1@dbname1] [user2:pass2@dbname2] [ignore_table1:ignore_table2...]"

dump () {
  up=${1%%@*}; user=${up%%:*}; pass=${up##*:}; dbname=${1##*@};
  mysqldump --opt --compact --skip-extended-insert -u $user -p$pass $dbname $table > $2
}

rm -f /tmp/db.diff

# Compare
up=${1%%@*}; user=${up%%:*}; pass=${up##*:}; dbname=${1##*@};
for table in `mysql -u $user -p$pass $dbname -N -e "show tables" --batch`; do
  if [ "`echo $3 | grep $table`" = "" ]; then
    echo "Comparing '$table'..."
    dump $1 /tmp/file1.sql
    dump $2 /tmp/file2.sql
    diff -up /tmp/file1.sql /tmp/file2.sql >> /tmp/db.diff
  else
    echo "Ignored '$table'..."
  fi
done
less /tmp/db.diff
rm -f /tmp/file1.sql /tmp/file2.sql

Feedback is welcome :)

The SSL certificates are going to be bound to hostname rather than IP if they are setup in the standard way. Hence why it works at one site rather than the other.

Even if the servers share the same hostname they may well have two different certificates and hence WebSphere will have a certificate trust issue as it won't be able to recognise the certificate on the second server as it is different to the first.

You're talking about histograms, but this doesn't quite make sense. Histograms and bar charts are different things. An histogram would be a bar chart representing the sum of values per year, for example. Here, you just seem to be after bars.

Here is a complete example from your data that shows a bar of for each required value at each date:

import pylab as pl
import datetime

data = """0 14-11-2003
1 15-03-1999
12 04-12-2012
33 09-05-2007
44 16-08-1998
55 25-07-2001
76 31-12-2011
87 25-06-1993
118 16-02-1995
119 10-02-1981
145 03-05-2014"""

values = []
dates = []

for line in data.split("\n"):
    x, y = line.split()
    values.append(int(x))
    dates.append(datetime.datetime.strptime(y, "%d-%m-%Y").date())

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(dates, values, width=100)
ax.xaxis_date()

You need to parse the date with strptime and set the x-axis to use dates (as described in this answer).

If you're not interested in having the x-axis show a linear time scale, but just want bars with labels, you can do this instead:

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(range(len(dates)), values)

EDIT: Following comments, for all the ticks, and for them to be centred, pass the range to set_ticks (and move them by half the bar width):

fig = pl.figure()
ax = pl.subplot(111)
width=0.8
ax.bar(range(len(dates)), values, width=width)
ax.set_xticks(np.arange(len(dates)) + width/2)
ax.set_xticklabels(dates, rotation=90)

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

Applying the Observer Pattern with delegates and events in c# is named "Event Pattern" according to MSDN which is a slight variation.

In this Article you will find well structured examples of how to apply the pattern in c# both the classic way and using delegates and events.

Exploring the Observer Design Pattern

public class Stock
{

    //declare a delegate for the event
    public delegate void AskPriceChangedHandler(object sender,
          AskPriceChangedEventArgs e);
    //declare the event using the delegate
    public event AskPriceChangedHandler AskPriceChanged;

    //instance variable for ask price
    object _askPrice;

    //property for ask price
    public object AskPrice
    {

        set
        {
            //set the instance variable
            _askPrice = value;

            //fire the event
            OnAskPriceChanged();
        }

    }//AskPrice property

    //method to fire event delegate with proper name
    protected void OnAskPriceChanged()
    {

        AskPriceChanged(this, new AskPriceChangedEventArgs(_askPrice));

    }//AskPriceChanged

}//Stock class

//specialized event class for the askpricechanged event
public class AskPriceChangedEventArgs : EventArgs
{

    //instance variable to store the ask price
    private object _askPrice;

    //constructor that sets askprice
    public AskPriceChangedEventArgs(object askPrice) { _askPrice = askPrice; }

    //public property for the ask price
    public object AskPrice { get { return _askPrice; } }

}//AskPriceChangedEventArgs

You can use JavaScript (don't need jQuery)

document.querySelectorAll('#selected li').length;

Try this; bear in mind that JavaScript months are 0-indexed, whilst days are 1-indexed.

var date = new Date('2010-10-11T00:00:00+05:30');_x000D_
    alert(((date.getMonth() > 8) ? (date.getMonth() + 1) : ('0' + (date.getMonth() + 1))) + '/' + ((date.getDate() > 9) ? date.getDate() : ('0' + date.getDate())) + '/' + date.getFullYear());

I Found some code for wordpress:

 <script type="text/javascript">

    function insert_pinterest($content) {
        global $post;
        $posturl = urlencode(get_permalink()); //Get the post URL
        $pinspan = '<span class="pinterest-button">';
     $pinurl = '';
     $pinend = '</span>';
        $pattern = '//i';
        $replacement = $pinspan.$pinurl.'$2.$3'.$pindescription.$pinfinish.''.$pinend;
        $content = preg_replace( $pattern, $replacement, $content );
        //Fix the link problem
        $newpattern = '/<span class="pinterest-button"><\/a><\/span><\/a>/i';
     $replacement = '';
     $content = preg_replace( $newpattern, $replacement, $content );
     return $content;
    }
    add_filter( 'the_content', 'insert_pinterest' );

    </script>

Then you put the following in your PHP:

<?php $pinterestimage = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' ); ?>
<a href="http://pinterest.com/pin/create/button/?url=<?php echo urlencode(get_permalink($post->ID)); ?>&media=<?php echo $pinterestimage[0]; ?>&description=<?php the_title(); ?>">Pin It</a>

You can get posted form data from request.form and query string data from request.args.

myvar =  request.form["myvar"]

myvar = request.args["myvar"]

In angular 1.4 +, in addition to adding the dependency

angular.module('myApp', ['ngRoute'])

,we also need to reference the separate angular-route.js file

<script src="angular.js">
<script src="angular-route.js">

see https://docs.angularjs.org/api/ngRoute

Using function in typescript

openWindow(){
    //you may choose to deduct some value from current screen size
    let height = window.screen.availHeight-100;
    let width = window.screen.availWidth-150;
    window.open("http://your_url",`width=${width},height=${height}`);
}

Dynamic resources can only be used when property being set is on object which is derived from dependency object or freezable where as static resources can be used anywhere. You can abstract away entire control using static resources.

Static resources are used under following circumstances:

1. When reaction resource changes at runtime is not required.
2. If you need a good performance with lots of resources.
3. While referencing resources within the same dictionary.

Dynamic resources:

1. Value of property or style setter theme is not known until runtime
   • This include system, aplication, theme based settings
   • This also includes forward references.
2. Referencing large resources that may not load when page, windows, usercontrol loads.
3. Referencing theme styles in a custom control.

I am using this from PowerShell:

dir -directory -name -recurse > list_my_folders.txt

One option from DOM directly:

$(document).find("title").text();

Tested only on chrome & IE9, but logically should work on all browsers.

Or more generic

var title = document.getElementsByTagName("title")[0].innerHTML;

Just declare

var trialImage;

outside. Then

function makeObj(address) {
    trialImage = [address, 50, 50];
    ...
    ...
}

Could not commit JPA transaction: Transaction marked as rollbackOnly

This exception occurs when you invoke nested methods/services also marked as @Transactional. JB Nizet explained the mechanism in detail. I'd like to add some scenarios when it happens as well as some ways to avoid it.

Suppose we have two Spring services: Service1 and Service2. From our program we call Service1.method1() which in turn calls Service2.method2():

class Service1 {
    @Transactional
    public void method1() {
        try {
            ...
            service2.method2();
            ...
        } catch (Exception e) {
            ...
        }
    }
}

class Service2 {
    @Transactional
    public void method2() {
        ...
        throw new SomeException();
        ...
    }
}

SomeException is unchecked (extends RuntimeException) unless stated otherwise.

Scenarios:

1. Transaction marked for rollback by exception thrown out of method2. This is our default case explained by JB Nizet.

2. Annotating method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

3. Annotating both method1 and method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

4. Annotating method2 with @Transactional(noRollbackFor = SomeException) prevents marking transaction for rollback (no exception thrown when exiting from method1).

5. Suppose method2 belongs to Service1. Invoking it from method1 does not go through Spring's proxy, i.e. Spring is unaware of SomeException thrown out of method2. Transaction is not marked for rollback in this case.

6. Suppose method2 is not annotated with @Transactional. Invoking it from method1 does go through Spring's proxy, but Spring pays no attention to exceptions thrown. Transaction is not marked for rollback in this case.

7. Annotating method2 with @Transactional(propagation = Propagation.REQUIRES_NEW) makes method2 start new transaction. That second transaction is marked for rollback upon exit from method2 but original transaction is unaffected in this case (no exception thrown when exiting from method1).

8. In case SomeException is checked (does not extend RuntimeException), Spring by default does not mark transaction for rollback when intercepting checked exceptions (no exception thrown when exiting from method1).

See all scenarios tested in this gist.

I got this error message when I entered a number (999999) that was out of the range I'd set for the form.

<input type="number" ng-model="clipInMovieModel" id="clipInMovie" min="1" max="10000">

Your expression is never going to evaluate.

You are comparing a with a property of a.

a is of type Answer. a.Correct, I'm guessing is a boolean.

Long form:-

Answer = answer.SingleOrDefault(a => a.Correct == true);

Short form:-

Answer = answer.SingleOrDefault(a => a.Correct);

There is no need to do two checks, why not just check for count = 3:

GROUP BY meetingID
HAVING COUNT(caseID) = 3

If you want to use the multiple checks, then you can use:

GROUP BY meetingID
HAVING COUNT(caseID) > 2
 AND COUNT(caseID) < 4

Standard javascript will do that using the following syntax:

string.substring(from, to)

var name = "nameGorge";
var output = name.substring(4);

Wow you're close. Edits in comments:

function add(type) {_x000D_
  //Create an input type dynamically.   _x000D_
  var element = document.createElement("input");_x000D_
  //Assign different attributes to the element. _x000D_
  element.type = type;_x000D_
  element.value = type; // Really? You want the default value to be the type string?_x000D_
  element.name = type; // And the name too?_x000D_
  element.onclick = function() { // Note this is a function_x000D_
    alert("blabla");_x000D_
  };_x000D_
_x000D_
  var foo = document.getElementById("fooBar");_x000D_
  //Append the element in page (in span).  _x000D_
  foo.appendChild(element);_x000D_
}_x000D_
document.getElementById("btnAdd").onclick = function() {_x000D_
  add("text");_x000D_
};

<input type="button" id="btnAdd" value="Add Text Field">_x000D_
<p id="fooBar">Fields:</p>

Now, instead of setting the onclick property of the element, which is called "DOM0 event handling," you might consider using addEventListener (on most browsers) or attachEvent (on all but very recent Microsoft browsers) — you'll have to detect and handle both cases — as that form, called "DOM2 event handling," has more flexibility. But if you don't need multiple handlers and such, the old DOM0 way works fine.

Separately from the above: You might consider using a good JavaScript library like jQuery, Prototype, YUI, Closure, or any of several others. They smooth over browsers differences like the addEventListener / attachEvent thing, provide useful utility features, and various other things. Obviously there's nothing a library can do that you can't do without one, as the libraries are just JavaScript code. But when you use a good library with a broad user base, you get the benefit of a huge amount of work already done by other people dealing with those browsers differences, etc.

stdbool.h was introduced in c99

Maybe you can try this: though please note - This pulls the column count, not the row count

 using (SqlDataReader reader = command.ExecuteReader())
 {
     while (reader.Read())
     {
         int count = reader.VisibleFieldCount;
         Console.WriteLine(count);
     }
 }

This question is about bootstrap date picker. But all of the above answers are for the jquery date picker. For Bootstrap datepicker, you just need to provide the defaut date in the value of the input element. Like this.

<input class="form-control datepicker" value=" <?= date("Y-m-d") ?>">

this is your code

ContactListActivityBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_contact_list);

Replace this code

ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_contact_list);

What you need is :

1) have a table body of limited height as scroll occurs only when contents is bigger than the scrolling window. However tbody cannot be sized, and you have to display it as a block to do so:

tbody {
   overflow-y: auto;
   display: block;
   max-height: 10em;    // For example
}

2) Re-sync table header and table body columns widths as making the latter a block made it an unrelated element. The only way to do so is to simulate synchronization by enforcing the same columns width to both.

However, since tbody itself is a block now, it can no longer behave like a table. Since you still need a table behavior to display you columns correctly, the solution is to ask for each of your rows to display as individual tables:

thead {         
   display: table;  
   width: 100%;     // Fill the containing table
}
tbody tr {
   display: table;
   width: 100%;     // Fill the containing table
}

(Note that, using this technique, you won't be able to span across rows anymore).

Once that done, you can enforce column widths to have the same width in both thead and tbody. You could not that:

• individually for each column (through specific CSS classes or inline styling), which is quite tedious to do for each table instance ;
• uniformly for all columns (through th, td { width: 20%; } if you have 5 columns for example), which is more practical (no need to set width for each table instance) but cannot work for any columns count
• uniformly for any columns count, through a fixed table layout.

I prefer the last option, which requires adding:

thead {
   table-layout: fixed;   // Same layout for all cells
}
tbody tr {
   table-layout: fixed;   // Same layout for all cells
}
th, td {
   width: auto;   // Same width for all cells, if table has fixed layout
}

Open Vim, and in normal mode type:

:echo $VIM

If a PEM contains only one RSA private key without encryption, it must be an ASN.1 sequence structure including 9 numbers to present a Chinese Remainder Theorem (CRT) key:

1. version (always 0)
2. modulus (n)
3. public exponent (e, always 65537)
4. private exponent (d)
5. prime p
6. prime q
7. d mod (p - 1) (dp)
8. d mod (q - 1) (dq)
9. q^-1 mod p (qinv)

We can implement an RSAPrivateCrtKey:

class RSAPrivateCrtKeyImpl implements RSAPrivateCrtKey {
    private static final long serialVersionUID = 1L;

    BigInteger n, e, d, p, q, dp, dq, qinv;

    @Override
    public BigInteger getModulus() {
        return n;
    }

    @Override
    public BigInteger getPublicExponent() {
        return e;
    }

    @Override
    public BigInteger getPrivateExponent() {
        return d;
    }

    @Override
    public BigInteger getPrimeP() {
        return p;
    }

    @Override
    public BigInteger getPrimeQ() {
        return q;
    }

    @Override
    public BigInteger getPrimeExponentP() {
        return dp;
    }

    @Override
    public BigInteger getPrimeExponentQ() {
        return dq;
    }

    @Override
    public BigInteger getCrtCoefficient() {
        return qinv;
    }

    @Override
    public String getAlgorithm() {
        return "RSA";
    }

    @Override
    public String getFormat() {
        throw new UnsupportedOperationException();
    }

    @Override
    public byte[] getEncoded() {
        throw new UnsupportedOperationException();
    }
}

Then read the private key from a PEM file:

import sun.security.util.DerInputStream;
import sun.security.util.DerValue;

static RSAPrivateCrtKey getRSAPrivateKey(String keyFile) {
    RSAPrivateCrtKeyImpl prvKey = new RSAPrivateCrtKeyImpl();
    try (BufferedReader in = new BufferedReader(new FileReader(keyFile))) {
        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = in.readLine()) != null) {
            // skip "-----BEGIN/END RSA PRIVATE KEY-----"
            if (!line.startsWith("--") || !line.endsWith("--")) {
                sb.append(line);
            }
        }
        DerInputStream der = new DerValue(Base64.
                getDecoder().decode(sb.toString())).getData();
        der.getBigInteger(); // 0
        prvKey.n = der.getBigInteger();
        prvKey.e = der.getBigInteger(); // 65537
        prvKey.d = der.getBigInteger();
        prvKey.p = der.getBigInteger();
        prvKey.q = der.getBigInteger();
        prvKey.dp = der.getBigInteger();
        prvKey.dq = der.getBigInteger();
        prvKey.qinv = der.getBigInteger();
    } catch (IllegalArgumentException | IOException e) {
        logger.warn(keyFile + ": " + e.getMessage());
        return null;
    }
}

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

You can use GREATEST function with not nullable fields. If one of this values (or both) can be NULL, don't use it (result can be NULL).

select 
    if(
        fieldA is NULL, 
        if(fieldB is NULL, NULL, fieldB), /* second NULL is default value */
        if(fieldB is NULL, field A, GREATEST(fieldA, fieldB))
    ) as maxValue

You can change NULL to your preferred default value (if both values is NULL).

Procedural generation only means that code is used to generate the data instead of it being hand made. For example if you want to generate a forest with various trees you are not going to design each tree by hand, thus coding is more efficient to generate the variations. It could be the generation of the tree graphics, size, structure, placement ...

In general there is some kind of interation with a few rules, in addition to that you can add some randomness and logic of your own, combine all of these techniques ... Anything somewhat chaotic but not too chaotic can yield interesting results.

Here are a few notable techniques:

First let's understand what big O, big Theta and big Omega are. They are all sets of functions.

Big O is giving upper asymptotic bound, while big Omega is giving a lower bound. Big Theta gives both.

Everything that is ?(f(n)) is also O(f(n)), but not the other way around.
T(n) is said to be in ?(f(n)) if it is both in O(f(n)) and in Omega(f(n)).
In sets terminology, ?(f(n)) is the intersection of O(f(n)) and Omega(f(n))

For example, merge sort worst case is both O(n*log(n)) and Omega(n*log(n)) - and thus is also ?(n*log(n)), but it is also O(n^2), since n^2 is asymptotically "bigger" than it. However, it is not ?(n^2), Since the algorithm is not Omega(n^2).

A bit deeper mathematic explanation

O(n) is asymptotic upper bound. If T(n) is O(f(n)), it means that from a certain n0, there is a constant C such that T(n) <= C * f(n). On the other hand, big-Omega says there is a constant C2 such that T(n) >= C2 * f(n))).

Do not confuse!

Not to be confused with worst, best and average cases analysis: all three (Omega, O, Theta) notation are not related to the best, worst and average cases analysis of algorithms. Each one of these can be applied to each analysis.

We usually use it to analyze complexity of algorithms (like the merge sort example above). When we say "Algorithm A is O(f(n))", what we really mean is "The algorithms complexity under the worst¹ case analysis is O(f(n))" - meaning - it scales "similar" (or formally, not worse than) the function f(n).

Why we care for the asymptotic bound of an algorithm?

Well, there are many reasons for it, but I believe the most important of them are:

1. It is much harder to determine the exact complexity function, thus we "compromise" on the big-O/big-Theta notations, which are informative enough theoretically.
2. The exact number of ops is also platform dependent. For example, if we have a vector (list) of 16 numbers. How much ops will it take? The answer is: it depends. Some CPUs allow vector additions, while other don't, so the answer varies between different implementations and different machines, which is an undesired property. The big-O notation however is much more constant between machines and implementations.

To demonstrate this issue, have a look at the following graphs:

It is clear that f(n) = 2*n is "worse" than f(n) = n. But the difference is not quite as drastic as it is from the other function. We can see that f(n)=logn quickly getting much lower than the other functions, and f(n) = n^2 is quickly getting much higher than the others.
So - because of the reasons above, we "ignore" the constant factors (2* in the graphs example), and take only the big-O notation.

In the above example, f(n)=n, f(n)=2*n will both be in O(n) and in Omega(n) - and thus will also be in Theta(n).
On the other hand - f(n)=logn will be in O(n) (it is "better" than f(n)=n), but will NOT be in Omega(n) - and thus will also NOT be in Theta(n).
Symetrically, f(n)=n^2 will be in Omega(n), but NOT in O(n), and thus - is also NOT Theta(n).

¹Usually, though not always. when the analysis class (worst, average and best) is missing, we really mean the worst case.

Look a regular expression http://regexone.com/lesson/misc_meta_characters

enjoy us ;-)

This is how I used this is as an example:

CAST(vAvgMaterialUnitCost.`avgUnitCost` AS DECIMAL(11,2)) * woMaterials.`qtyUsed` AS materialCost

I found an easy way to get the dictionary value, and its name as well! I'm not sure yet about reading it back, I'm going to continue to do research and see if I can figure that out.

Here is the code:

your_dict = {'one': 1, 'two': 2}

variables = [var for var in dir() if var[0:2] != "__" and var[-1:-2] != "__"]

file = open("your_file","w")
for var in variables:
     if isinstance(locals()[var], dict):
          file.write(str(var) + " = " + str(locals()[var]) + "\n")
file.close()

Only problem here is this will output every dictionary in your namespace to the file, maybe you can sort them out by values? locals()[var] == your_dict for reference.

You can also remove if isinstance(locals()[var], dict): to output EVERY variable in your namespace, regardless of type. Your output looks exactly like your decleration your_dict = {'one': 1, 'two': 2}.

Hopefully this gets you one step closer! I'll make an edit if I can figure out how to read them back into the namespace :)

---EDIT---

Got it! I've added a few variables (and variable types) for proof of concept. Here is what my "testfile.txt" looks like:

string_test = Hello World
integer_test = 42
your_dict = {'one': 1, 'two': 2}

And here is the code the processes it:

import ast

file = open("testfile.txt", "r")
data = file.readlines()
file.close()

for line in data:
    var_name, var_val = line.split(" = ")
    for possible_num_types in range(3):  # Range is the == number of types we will try casting to
        try:
            var_val = int(var_val)
            break
        except (TypeError, ValueError):
            try:
                var_val = ast.literal_eval(var_val)
                break
            except (TypeError, ValueError, SyntaxError):
                var_val = str(var_val).replace("\n","")
                break
    locals()[var_name] = var_val


print("string_test =", string_test, " :  Type =", type(string_test))
print("integer_test =", integer_test, " :  Type =", type(integer_test))
print("your_dict =", your_dict, " :  Type =", type(your_dict))

This is what that outputs:

string_test = Hello World  :  Type = <class 'str'>
integer_test = 42  :  Type = <class 'int'>
your_dict = {'two': 2, 'one': 1}  :  Type = <class 'dict'>

I really don't like how the casting here works, the try-except block is bulky and ugly. Even worse, you cannot accept just any type! You have to know what you are expecting to take in. This wouldn't be nearly as bad if you only cared about dictionaries, but I really wanted something a bit more universal.

If anybody knows how to better cast these input vars I would LOVE to hear about it!

Regardless, this should still get you there :D I hope I've helped out!

It has no meaning, it is just a file extension. It is some people's convention to name files with a .inc extension if that file is designed to be included by other PHP files, but it is only convention.

It does have a possible disadvantage which is that servers normally are not configured to parse .inc files as php, so if the file sits in your web root and your server is configured in the default way, a user could view your php source code in the .inc file by visiting the URL directly.

Its only possible advantage is that it is easy to identify which files are used as includes. Although simply giving them a .php extension and placing them in an includes folder has the same effect without the disadvantage mentioned above.

I believe using * invalidate the entire cache in the distribution. I am trying at the moment, I would update it further

Update:

It worked as expected. Please note that you can invalidate the object you would like by specifying the object path.

It might help you! Please see below steps.

There are a few npm libraries for cancellable promises.

1. p-cancelable https://github.com/sindresorhus/p-cancelable

2. cancelable-promise https://github.com/alkemics/CancelablePromise

When calling super() to resolve to a parent's version of a classmethod, instance method, or staticmethod, we want to pass the current class whose scope we are in as the first argument, to indicate which parent's scope we're trying to resolve to, and as a second argument the object of interest to indicate which object we're trying to apply that scope to.

Consider a class hierarchy A, B, and C where each class is the parent of the one following it, and a, b, and c respective instances of each.

super(B, b) 
# resolves to the scope of B's parent i.e. A 
# and applies that scope to b, as if b was an instance of A

super(C, c) 
# resolves to the scope of C's parent i.e. B
# and applies that scope to c

super(B, c) 
# resolves to the scope of B's parent i.e. A 
# and applies that scope to c

Using super with a staticmethod

e.g. using super() from within the __new__() method

class A(object):
    def __new__(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        return super(A, cls).__new__(cls, *a, **kw)

Explanation:

1- even though it's usual for __new__() to take as its first param a reference to the calling class, it is not implemented in Python as a classmethod, but rather a staticmethod. That is, a reference to a class has to be passed explicitly as the first argument when calling __new__() directly:

# if you defined this
class A(object):
    def __new__(cls):
        pass

# calling this would raise a TypeError due to the missing argument
A.__new__()

# whereas this would be fine
A.__new__(A)

2- when calling super() to get to the parent class we pass the child class A as its first argument, then we pass a reference to the object of interest, in this case it's the class reference that was passed when A.__new__(cls) was called. In most cases it also happens to be a reference to the child class. In some situations it might not be, for instance in the case of multiple generation inheritances.

super(A, cls)

3- since as a general rule __new__() is a staticmethod, super(A, cls).__new__ will also return a staticmethod and needs to be supplied all arguments explicitly, including the reference to the object of insterest, in this case cls.

super(A, cls).__new__(cls, *a, **kw)

4- doing the same thing without super

class A(object):
    def __new__(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        return object.__new__(cls, *a, **kw)

Using super with an instance method

e.g. using super() from within __init__()

class A(object): 
    def __init__(self, *a, **kw):
        # ...
        # you make some changes here
        # ...

        super(A, self).__init__(*a, **kw)

Explanation:

1- __init__ is an instance method, meaning that it takes as its first argument a reference to an instance. When called directly from the instance, the reference is passed implicitly, that is you don't need to specify it:

# you try calling `__init__()` from the class without specifying an instance
# and a TypeError is raised due to the expected but missing reference
A.__init__() # TypeError ...

# you create an instance
a = A()

# you call `__init__()` from that instance and it works
a.__init__()

# you can also call `__init__()` with the class and explicitly pass the instance 
A.__init__(a)

2- when calling super() within __init__() we pass the child class as the first argument and the object of interest as a second argument, which in general is a reference to an instance of the child class.

super(A, self)

3- The call super(A, self) returns a proxy that will resolve the scope and apply it to self as if it's now an instance of the parent class. Let's call that proxy s. Since __init__() is an instance method the call s.__init__(...) will implicitly pass a reference of self as the first argument to the parent's __init__().

4- to do the same without super we need to pass a reference to an instance explicitly to the parent's version of __init__().

class A(object): 
    def __init__(self, *a, **kw):
        # ...
        # you make some changes here
        # ...

        object.__init__(self, *a, **kw)

Using super with a classmethod

class A(object):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        print "A.alternate_constructor called"
        return cls(*a, **kw)

class B(A):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        print "B.alternate_constructor called"
        return super(B, cls).alternate_constructor(*a, **kw)

Explanation:

1- A classmethod can be called from the class directly and takes as its first parameter a reference to the class.

# calling directly from the class is fine,
# a reference to the class is passed implicitly
a = A.alternate_constructor()
b = B.alternate_constructor()

2- when calling super() within a classmethod to resolve to its parent's version of it, we want to pass the current child class as the first argument to indicate which parent's scope we're trying to resolve to, and the object of interest as the second argument to indicate which object we want to apply that scope to, which in general is a reference to the child class itself or one of its subclasses.

super(B, cls_or_subcls)

3- The call super(B, cls) resolves to the scope of A and applies it to cls. Since alternate_constructor() is a classmethod the call super(B, cls).alternate_constructor(...) will implicitly pass a reference of cls as the first argument to A's version of alternate_constructor()

super(B, cls).alternate_constructor()

4- to do the same without using super() you would need to get a reference to the unbound version of A.alternate_constructor() (i.e. the explicit version of the function). Simply doing this would not work:

class B(A):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        print "B.alternate_constructor called"
        return A.alternate_constructor(cls, *a, **kw)

The above would not work because the A.alternate_constructor() method takes an implicit reference to A as its first argument. The cls being passed here would be its second argument.

class B(A):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        print "B.alternate_constructor called"
        # first we get a reference to the unbound 
        # `A.alternate_constructor` function 
        unbound_func = A.alternate_constructor.im_func
        # now we call it and pass our own `cls` as its first argument
        return unbound_func(cls, *a, **kw)

In some cases (like poorly designed iterators), the class needs to keep a count or some other incidental value, that doesn't really affect the major "state" of the class. This is most often where I see mutable used. Without mutable, you'd be forced to sacrifice the entire const-ness of your design.

It feels like a hack most of the time to me as well. Useful in a very very few situations.

Agreed with the answer from sll, but experienced another hurdle which was having specified a namespace in the attributes, when receiving the return xml that namespace wasn't included and thus failed finding the class.

i had to find a workaround to specifying the namespace in the attribute and it worked.

ie.

[Serializable()]
    [XmlRoot("Patient", Namespace = "http://www.xxxx.org/TargetNamespace")]
    public class Patient

generated

<Patient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.xxxx.org/TargetNamespace">

but I had to change it to

[Serializable()]
[XmlRoot("Patient")]
public class Patient

which generated to

<Patient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

This solved my problem, hope it helps someone else.

It might be beneficial to add greedy matching to the end of the string, so you can accept strings > than 10 and the regex will only return up to the first 10 chars. /^[a-z0-9]{0,10}$?/

To import module as library in your project.

1. File > New > Import Module
2. Select Valid path in Source Dir..
3. Tick on Import > Finish

Now Open Module setting:

1. Go to File > Project Structure > Modules
2. Modules > Dependency > click on Green Plus Sign.
3. Click on Module Dependency > locate module > and Implement your module.

if your module is not shown in "Choose Modules Window"

Follow the below step..

1. Open Settings.Gradle file
2. include ':app', 'Put your module name here' and sync project.

Follow Open Module Setting as above.

In my case i have got a different solution in case any one need

yarn remove react-native-material-dropdown

Install new packages react-native-material-dropdown-v2

yarn add react-native-material-dropdown-v2

Replace react-native-material-dropdown with react-native-material-dropdown-v2 in your code

e.g. import { Dropdown } from 'react-native-material-dropdown' to import { Dropdown } from 'react-native-material-dropdown-v2'

another thing ==========

1. Open node_modules and then search for react-native-material-textfield open the file and go to src folder
2. Under src you will see affix, helper, label folder - under each folder, there is an index.js
3. open the index.js of the mentioned folders one by one (all 3 folders) and search for the text style: Animated.Text.propTypes.style, and replace it by style: Text.propTypes
4. And import text form react-native like this import { Animated , Text} from 'react-native';

you need to add it to Foo's prototype:

function Foo(){}
Foo.prototype.bar = function(){}
var x = new Foo()
x.bar()

Type this:

mysql --help 

Then look at the output. There is a block of text about 3/4 the way down describing what files it finds its defaults .my.cnf from. Here is an example from XAMPP v3.2.1:

Default options are read from the following files in the given order:
C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf C:\xampp\mysql\bin\my.ini C:\xampp\mysql\bin\my.cnf

Your setup may differ. You will have to run the command to check the actual paths on your particular system.

I used a combination of not showing links in google, adding links for mso (outlook) and the shy tag, to keep the looks and feels for my company.

I know this is old and already answered but I was actually looking for this. I am posting this answer to save people a little time refining some of the answers.

Option 1:

$data = array('$FooBar');  

$vars = [];  
$vars = preg_replace('/^\\$/', '', $data); 

$varname = key(compact($vars));  
echo $varname;

Prints:

FooBar

For whatever reason you would find yourself in a situation like this, it does actually work.

.
Option 2:

$FooBar = "a string";  

$varname = trim(array_search($FooBar, $GLOBALS), " \t.");  
echo $varname;

If $FooBar holds a unique value, it will print 'FooBar'. If $FooBar is empty or null it will print the name of the first empty or null string it finds.

It could be used as such:

if (isset($FooBar) && !is_null($FooBar) && !empty($FooBar)) {
    $FooBar = "a string";
    $varname = trim(array_search($FooBar, $GLOBALS), " \t.");
}

declare your date column as NOT NULL, but without a default. Then add this trigger:

USE `ddb`;
DELIMITER $$
CREATE TRIGGER `default_date` BEFORE INSERT ON `dtable` FOR EACH ROW
if ( isnull(new.query_date) ) then
 set new.query_date=curdate();
end if;
$$
delimiter ;

For the beginner I would like to explain a bit more with an example:

Example:

value is 0x55;
bitnum : 3rd.

The & operator is used check the bit:

0101 0101
&
0000 1000
___________
0000 0000 (mean 0: False). It will work fine if the third bit is 1 (then the answer will be True)

Toggle or Flip:

0101 0101
^
0000 1000
___________
0101 1101 (Flip the third bit without affecting other bits)

| operator: set the bit

0101 0101
|
0000 1000
___________
0101 1101 (set the third bit without affecting other bits)

I want to add for one more possibility. If you don't want to use TypeToken and want to convert json objects array to an ArrayList, then you can proceed like this:

If your json structure is like:

{

"results": [
    {
        "a": 100,
        "b": "value1",
        "c": true
    },
    {
        "a": 200,
        "b": "value2",
        "c": false
    },
    {
        "a": 300,
        "b": "value3",
        "c": true
    }
]

}

and your class structure is like:

public class ClassName implements Parcelable {

    public ArrayList<InnerClassName> results = new ArrayList<InnerClassName>();
    public static class InnerClassName {
        int a;
        String b;
        boolean c;      
    }
}

then you can parse it like:

Gson gson = new Gson();
final ClassName className = gson.fromJson(data, ClassName.class);
int currentTotal = className.results.size();

Now you can access each element of className object.

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

Python has good options to scrape the web. The best one with a framework is scrapy. It can be a little tricky for beginners, so here is a little help.
1. Install python above 3.5 (lower ones till 2.7 will work).
2. Create a environment in conda ( I did this).
3. Install scrapy at a location and run in from there.
4. Scrapy shell will give you an interactive interface to test you code.
5. Scrapy startproject projectname will create a framework.
6. Scrapy genspider spidername will create a spider. You can create as many spiders as you want. While doing this make sure you are inside the project directory.

The easier one is to use requests and beautiful soup. Before starting give one hour of time to go through the documentation, it will solve most of your doubts. BS4 offer wide range of parsers that you can opt for. Use user-agent and sleep to make scraping easier. BS4 returns a bs.tag so use variable[0]. If there is js running, you wont be able to scrape using requests and bs4 directly. You could get the api link then parse the JSON to get the information you need or try selenium.

If you see table class it has border-spacing: 2px; You could override table class in your css and set its border-spacing: 0px!important in table; I did it like

table {
      border-collapse: separate;
      white-space: normal;
      line-height: normal;
      font-weight: normal;
      font-size: medium;
      font-style: normal;
      color: -internal-quirk-inherit;
      text-align: start;
      border-spacing: 0px!important;
      font-variant: normal;   }

It saved my day.Hope it would be of help. Thanks.

I haven't tested your code, just tried to help you understand how it operates in comment;

  AS
  (
-->>>>>>>>>>Block 1>>>>>>>>>>>>>>>>>
-- In a rCTE, this block is called an [Anchor]

    SELECT e.EmployeeID, e.FirstName, e.LastName, e.ManagerID,

  EmpLevel,
  (SELECT FirstName + ' ' + LastName FROM Employees
    WHERE EmployeeID = cteReports.MgrID) AS Manager
FROM cteReports
ORDER BY EmpLevel, MgrID

The simplest example of a recursive CTE I can think of to illustrate its operation is;

;WITH Numbers AS
(
    SELECT n = 1
    UNION ALL
    SELECT n + 1
    FROM Numbers
    WHERE n+1 <= 10
)
SELECT n
FROM Numbers

Q 1) how value of N is getting incremented. if value is assign to N every time then N value can be incremented but only first time N value was initialize.

A1: In this case, N is not a variable. N is an alias. It is the equivalent of SELECT 1 AS N. It is a syntax of personal preference. There are 2 main methods of aliasing columns in a CTE in T-SQL. I've included the analog of a simple CTE in Excel to try and illustrate in a more familiar way what is happening.

--  Outside
;WITH CTE (MyColName) AS
(
    SELECT 1
)
-- Inside
;WITH CTE AS
(
    SELECT 1 AS MyColName
    -- Or
    SELECT MyColName = 1  
    -- Etc...
)

Q 2) now here about CTE and recursion of employee relation the moment i add two manager and add few more employee under second manager then problem start. i want to display first manager detail and in the next rows only those employee details will come those who are subordinate of that manager

A2:

Does this code answer your question?

--------------------------------------------
-- Synthesise table with non-recursive CTE
--------------------------------------------
;WITH Employee (ID, Name, MgrID) AS 
(
    SELECT 1,      'Keith',      NULL   UNION ALL
    SELECT 2,      'Josh',       1      UNION ALL

    SELECT 7,      'Amit',       5      UNION ALL
    SELECT 8,      'Dev',        6   
)

            ,nLevel = 1
            ,Family = ROW_NUMBER() OVER (ORDER BY Name)
    FROM Employee
    WHERE MgrID IS NULL

    UNION ALL
    --  Recursive query
    SELECT   E.ID
            ,E.Name
            ,E.MgrID
            ,H.nLevel+1
            ,Family
    FROM Employee   E
    JOIN Hierarchy  H ON E.MgrID = H.ID
)
SELECT *
FROM Hierarchy
ORDER BY Family, nLevel

Another one sql with tree structure

SELECT ID,space(nLevel+
                    (CASE WHEN nLevel > 1 THEN nLevel ELSE 0 END)
                )+Name
FROM Hierarchy
ORDER BY Family, nLevel

You would use === to test whether a function or variable is false rather than just equating to false (zero or an empty string).

$needle = 'a';
$haystack = 'abc';
$pos = strpos($haystack, $needle);
if ($pos === false) {
    echo $needle . ' was not found in ' . $haystack;
} else {
    echo $needle . ' was found in ' . $haystack . ' at location ' . $pos;
}

In this case strpos would return 0 which would equate to false in the test

if ($pos == false)

or

if (!$pos)

which is not what you want here.

From RFC2616 section 14.9.1

You're missing an ending anchor.

if(Regex.IsMatch(myString, "^[A-Za-z]{2}[0-9]{2}\z")) {
    // ...
}

Here's a demo.

EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:

if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {
    // ...
}

Here's a demo.

I posted a CodeProject article that may be what you want.

See: A C# way for indirect width and style formatting.

Basically it is a method, FormatEx, that acts like String.Format, except it allows a centered alignment modifier.

FormatEx("{0,c10}", value);

Means center the value of varArgs[0] in a 10 character wide field, lean right if an extra padding space is required.

FormatEx("{0,c-10}", value);

Means center the value of varArgs[0] in a 10 character wide field, lean left if an extra padding space is required.

Edit: Internally, it is a combination of Joel's PadCenter with some parsing to restructure the format and varArgs for a call to String.Format that does what you want.

-Jesse

You can use %s or .format:

>>> "%s" % 10
'10'
>>>

Or:

>>> '{}'.format(10)
'10'
>>>

You can't cast an Object array to an Integer array. You have to loop through all elements of a and cast each one individually.

Object[] a = new Object[1];
Integer b=1;
a[0]=b;
Integer[] c = new Integer[a.length];
for(int i = 0; i < a.length; i++)
{
    c[i] = (Integer) a[i];
}

Edit: I believe the rationale behind this restriction is that when casting, the JVM wants to ensure type-safety at runtime. Since an array of Objects can be anything besides Integers, the JVM would have to do what the above code is doing anyway (look at each element individually). The language designers decided they didn't want the JVM to do that (I'm not sure why, but I'm sure it's a good reason).

However, you can cast a subtype array to a supertype array (e.g. Integer[] to Object[])!

I don't believe there's a way to query the mouse position, but you can use a mousemove handler that just stores the information away, so you can query the stored information.

jQuery(function($) {
    var currentMousePos = { x: -1, y: -1 };
    $(document).mousemove(function(event) {
        currentMousePos.x = event.pageX;
        currentMousePos.y = event.pageY;
    });

    // ELSEWHERE, your code that needs to know the mouse position without an event
    if (currentMousePos.x < 10) {
        // ....
    }
});

But almost all code, other than setTimeout code and such, runs in response to an event, and most events provide the mouse position. So your code that needs to know where the mouse is probably already has access to that information...

mysqldump can take a tbl_name parameter, so that it only backups the given tables.

mysqldump -u -p yourdb yourtable > c:\backups\backup.sql

I would be radical. No BigDecimal.

Here is a great article https://lemnik.wordpress.com/2011/03/25/bigdecimal-and-your-money/

Ideas from here.

import java.math.BigDecimal;

public class Main {

    public static void main(String[] args) {
        testConstructors();
        testEqualsAndCompare();
        testArithmetic();
    }

    private static void testEqualsAndCompare() {
        final BigDecimal zero = new BigDecimal("0.0");
        final BigDecimal zerozero = new BigDecimal("0.00");

        boolean zerosAreEqual = zero.equals(zerozero);
        boolean zerosAreEqual2 = zerozero.equals(zero);

        System.out.println("zerosAreEqual: " + zerosAreEqual + " " + zerosAreEqual2);

        int zerosCompare = zero.compareTo(zerozero);
        int zerosCompare2 = zerozero.compareTo(zero);
        System.out.println("zerosCompare: " + zerosCompare + " " + zerosCompare2);
    }

    private static void testArithmetic() {
        try {
            BigDecimal value = new BigDecimal(1);
            value = value.divide(new BigDecimal(3));
            System.out.println(value);
        } catch (ArithmeticException e) {
            System.out.println("Failed to devide. " + e.getMessage());
        }
    }

    private static void testConstructors() {
        double doubleValue = 35.7;
        BigDecimal fromDouble = new BigDecimal(doubleValue);
        BigDecimal fromString = new BigDecimal("35.7");

        boolean decimalsEqual = fromDouble.equals(fromString);
        boolean decimalsEqual2 = fromString.equals(fromDouble);

        System.out.println("From double: " + fromDouble);
        System.out.println("decimalsEqual: " + decimalsEqual + " " + decimalsEqual2);
    }
}

It prints

From double: 35.7000000000000028421709430404007434844970703125
decimalsEqual: false false
zerosAreEqual: false false
zerosCompare: 0 0
Failed to devide. Non-terminating decimal expansion; no exact representable decimal result.

How about storing BigDecimal into a database? Hell, it also stores as a double value??? At least, if I use mongoDb without any advanced configuration it will store BigDecimal.TEN as 1E1.

Possible solutions?

I came with one - use String to store BigDecimal in Java as a String into the database. You have validation, for example @NotNull, @Min(10), etc... Then you can use a trigger on update or save to check if current string is a number you need. There are no triggers for mongo though. Is there a built-in way for Mongodb trigger function calls?

There is one drawback I am having fun around - BigDecimal as String in Swagger defenition

I need to generate swagger, so our front-end team understands that I pass them a number presented as a String. DateTime for example presented as a String.

There is another cool solution I read in the article above... Use long to store precise numbers.

A standard long value can store the current value of the Unites States national debt (as cents, not dollars) 6477 times without any overflow. Whats more: it’s an integer type, not a floating point. This makes it easier and accurate to work with, and a guaranteed behavior.

Update

https://stackoverflow.com/a/27978223/4587961

Maybe in the future MongoDb will add support for BigDecimal. https://jira.mongodb.org/browse/SERVER-1393 3.3.8 seems to have this done.

It is an example of the second approach. Use scaling. http://www.technology-ebay.de/the-teams/mobile-de/blog/mapping-bigdecimals-with-morphia-for-mongodb.html

Just need to add 2 attributes for asp button :

OnClientClick="this.disabled='true';"  UseSubmitBehavior="false"

e.g.

<asp:Button ID="Button1" runat="server" Text="TEST" OnClientClick="this.disabled='true';"  UseSubmitBehavior="false" CssClass="button-content btnwidth" OnClick="ServerSideMethod_Click"  />

For more details:

https://bytes.com/topic/asp-net/answers/918280-disable-button-click-prevent-multiple-postbacks

could also use following as per the php manual comment

$_SERVER['REDIRECT_URL']

Please note this is working only for certain PHP environment only and follow the bellow comment from that page for more information;

Purpose: The URL path name of the current PHP file, path-info is N/A and excluding URL query string. Includes leading slash.

Caveat: This is before URL rewrites (i.e. it's as per the original call URL).

Caveat: Not set on all PHP environments, and definitely only ones with URL rewrites.

Works on web mode: Yes

Works on CLI mode: No

DirBuster is such a hacking script that guesses a bunch of common names as nsanders had mentioned. It literally brute forces lists of common words and file endings (.html, .php) and over time figures out the directory structure of such sites, this could discover the page as you described but would also discover many others.

I experienced this problem when I accidentally set "Chrome" to be the default browser for debugging. When I set it back to "IE" the problem disappeared. I am not sure why...

EDIT: I was about to delete this answer, because I wasn't sure about it, but then I had the problem again. I switched to browsing with Chrome, then back again to IE and it stopped! What gives!?

Passing the :value option to f.label will ensure the label tag's for attribute is the same as the id of the corresponding radio_button

<% form_for(@message) do |f| %>
  <%= f.radio_button :contactmethod, 'email' %> 
  <%= f.label :contactmethod, 'Email', :value => 'email' %>
  <%= f.radio_button :contactmethod, 'sms' %>
  <%= f.label :contactmethod, 'SMS', :value => 'sms' %>
<% end %>

See ActionView::Helpers::FormHelper#label

the :value option, which is designed to target labels for radio_button tags

urls.py:

#...    
url(r'element/update/(?P<pk>\d+)/$', 'element.views.element_update', name='element_update'),

views.py:

from django.shortcuts import redirect
from .models import Element


def element_info(request):
    # ...
    element = Element.object.get(pk=1)
    return redirect('element_update', pk=element.id)

def element_update(request, pk)
    # ...

The way I've done it before is basically like what you wrote, but doesn't have any hardcoded values:

if($_SERVER["HTTPS"] != "on")
{
    header("Location: https://" . $_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"]);
    exit();
}

For skipping memory limit and version error use the code below:

COMPOSER_MEMORY_LIMIT=-1 composer require <package-name> --ignore-platform-reqs

Another potential cause for this error: Attempting to get permission for a Facebook app in sandbox mode when the Facebook user is not listed in the app's admins, developers or testers.

If you specify CSS attributes for your body element it should apply to anything within <body></body> so long as you don't override them later in the stylesheet.

I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):

    public ActionResult ExportToExcel()
    {
        var products = new System.Data.DataTable("teste");
        products.Columns.Add("col1", typeof(int));
        products.Columns.Add("col2", typeof(string));

        products.Rows.Add(1, "product 1");
        products.Rows.Add(2, "product 2");
        products.Rows.Add(3, "product 3");
        products.Rows.Add(4, "product 4");
        products.Rows.Add(5, "product 5");
        products.Rows.Add(6, "product 6");
        products.Rows.Add(7, "product 7");


        var grid = new GridView();
        grid.DataSource = products;
        grid.DataBind();

        Response.ClearContent();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
        Response.ContentType = "application/ms-excel";

        Response.Charset = "";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);

        grid.RenderControl(htw);

        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();

        return View("MyView");
    }

This query should be written before the query which create or update data in the database, this query looks like :

mysql_query("set names 'utf8'");

Note that you should write the encode which you are using in the header for example if you are using utf-8 you add it like this in the header or it will couse a problem with Internet Explorer

so your page looks like this

<html>
    <head>
        <title>page title</title>
        <meta charset="UTF-8" />   
    </head>
    <body>
    <?php
            mysql_query("set names 'utf8'");   
            $sql = "INSERT * FROM ..... ";  
            mysql_query($sql);
    ?>    

    </body>
</html>

google.maps.event.addListener(marker, 'click', (function(marker, i) {
  return function() {
    window.location.href = marker.url;
  }
})(marker, i));

If you're not using Homebrew, this is what I just did on MAC OS X Lion (10.7.5):

1. Get the latest version of the ZSH sourcecode

2. Untar the download into its own directory then install: ./configure && make && make test && sudo make install

3. This installs the the zsh binary at /usr/local/bin/zsh.

4. You can now use the shell by loading up a new terminal and executing the binary directly, but you'll want to make it your default shell...

5. To make it your default shell you must first edit /etc/shells and add the new path. Then you can either run chsh -s /usr/local/bin/zsh or go to System Preferences > Users & Groups > right click your user > Advanced Options... > and then change "Login shell".

6. Load up a terminal and check you're now in the correct version with echo $ZSH_VERSION. (I wasn't at first, and it took me a while to figure out I'd configured iTerm to use a specific shell instead of the system default).

You should be using the strict not equals comparison operator !== so that if the user inputs "null" then you won't get to the else.

This is browser specific behavior and is a way for making filling up forms more convenient to users (like reloading the page when an error has been encountered and not losing what they just typed). So there is no sure way to disable this across browsers short of setting the default values on page load using javascript.

Firefox though seems to disable this feature when you specify the header:

Cache-Control: no-store

See this question.

Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.

[Update] As mentioned by @Aftershock in the comments, util.pump is gone and was replaced with a method on the Stream prototype called pipe; the code below reflects this.

var http = require('http'),
    fileSystem = require('fs'),
    path = require('path');

http.createServer(function(request, response) {
    var filePath = path.join(__dirname, 'myfile.mp3');
    var stat = fileSystem.statSync(filePath);

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size
    });

    var readStream = fileSystem.createReadStream(filePath);
    // We replaced all the event handlers with a simple call to readStream.pipe()
    readStream.pipe(response);
})
.listen(2000);

Taken from http://elegantcode.com/2011/04/06/taking-baby-steps-with-node-js-pumping-data-between-streams/

Use below method to get current time stamp. It works fine for me.

/**
 * 
 * @return yyyy-MM-dd HH:mm:ss formate date as string
 */
public static String getCurrentTimeStamp(){
    try {

        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String currentDateTime = dateFormat.format(new Date()); // Find todays date

        return currentDateTime;
    } catch (Exception e) {
        e.printStackTrace();

        return null;
    }
}

You're so close it's crazy.

if($(this).attr("name"))

There's no hasAttr but hitting an attribute by name will just return undefined if it doesn't exist.

This is why the below works. If you remove the name attribute from #heading the second alert will fire.

Update: As per the comments, the below will ONLY work if the attribute is present AND is set to something not if the attribute is there but empty

<script type="text/javascript">
$(document).ready(function()
{
    if ($("#heading").attr("name"))
      alert('Look, this is showing because it\'s not undefined');
    else
      alert('This would be called if it were undefined or is there but empty');
});
</script>
<h1 id="heading" name="bob">Welcome!</h1>

g.next() has been renamed to g.__next__(). The reason for this is consistency: special methods like __init__() and __del__() all have double underscores (or "dunder" in the current vernacular), and .next() was one of the few exceptions to that rule. This was fixed in Python 3.0. [*]

But instead of calling g.__next__(), use next(g).

[*] There are other special attributes that have gotten this fix; func_name, is now __name__, etc.

After you install Oracle Client components on the remote server, restart SQL Server Agent from the PC Management Console or directly from Sql Server Management Studio. This will allow the service to load correctly the path to the Oracle components. Otherwise your package will work on design time but fail on run time.

The page has to be launched from the Home screen for the meta tag to work.

I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.

Just put the data you want to send as second parameter:

$http.post('request-url',  message);

Another form which also works is:

$http.post('request-url',  { params: { paramName: value } });

Make sure that paramName exactly matches the name of the parameter of the function you are calling.

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

@x can be changed.

I know it's an old question. But it keeps showing in google first position and all it says it's "install node.js". For a newbie this is not obvious, so all you have to do is go to the node.js website and search for the command for your linux distribution version or any other operating system. Here is the link: https://nodejs.org/en/download/package-manager/

In this page you have to choose your operating system and you'll find your command. Then you just log into your console as a root (using putty for instance) and execute that command.

After that, you log as normal user and go again inside your laravel application folder and run again npm install command, and it should work. Hope it helps.

If this is about .css and .js changes, one way is to to "cache busting" is by appending something like "_versionNo" to the file name for each release. For example:

script_1.0.css // This is the URL for release 1.0
script_1.1.css // This is the URL for release 1.1
script_1.2.css // etc.

Or alternatively do it after the file name:

script.css?v=1.0 // This is the URL for release 1.0
script.css?v=1.1 // This is the URL for release 1.1
script.css?v=1.2 // etc.

You can check out this link to see how it could work.

If it's just for passing values between pages and you only require it for the one request. Use Context.

Context

The Context object holds data for a single user, for a single request, and it is only persisted for the duration of the request. The Context container can hold large amounts of data, but typically it is used to hold small pieces of data because it is often implemented for every request through a handler in the global.asax. The Context container (accessible from the Page object or using System.Web.HttpContext.Current) is provided to hold values that need to be passed between different HttpModules and HttpHandlers. It can also be used to hold information that is relevant for an entire request. For example, the IBuySpy portal stuffs some configuration information into this container during the Application_BeginRequest event handler in the global.asax. Note that this only applies during the current request; if you need something that will still be around for the next request, consider using ViewState. Setting and getting data from the Context collection uses syntax identical to what you have already seen with other collection objects, like the Application, Session, and Cache. Two simple examples are shown here:

// Add item to
Context Context.Items["myKey"] = myValue;

// Read an item from the
 Context Response.Write(Context["myKey"]);

http://msdn.microsoft.com/en-us/magazine/cc300437.aspx#S6

Using the above. If you then do a Server.Transfer the data you've saved in the context will now be available to the next page. You don't have to concern yourself with removing/tidying up this data as it is only scoped to the current request.

Or you could use something like the following. Pay attention to "\n":

Here's what I did:

After building Macvim I copied mvim to one of my $PATH destinations (In this case I chose /usr/local/bin)

cp -v [MacVim_source_folder]/src/MacVim/mvim /usr/local/bin

Then when you invoke mvim it is now recognised but there is an annoying thing. It opens the visual MacVim window, not the one in terminal. To do that, you have to invoke

mvim -v

To make sure every time you call mvim you don't have to remember to add the '-v' you can create an alias:

alias mvim='mvim -v'

However, this alias will only persist for this session of the Terminal. To have this alias executed every time you open a Terminal window, you have to include it in your .profile The .profile should be in your home directory. If it's not, create it.

cd ~
mvim -v .profile

include the alias command in there and save it.

That's it.

You should take care with readLines(...) and big files. Reading all lines at memory can be risky. Below is a example of how to read file and process just one line at time:

processFile = function(filepath) {
  con = file(filepath, "r")
  while ( TRUE ) {
    line = readLines(con, n = 1)
    if ( length(line) == 0 ) {
      break
    }
    print(line)
  }

  close(con)
}

Understand the risk of reading a line at memory too. Big files without line breaks can fill your memory too.

All other answer are correct, but remember that if you cast double to int you will loss decimal value.. so 2.9 double become 2 int.

You can use Math.round(double) function or simply do :

(int)(yourDoubleValue + 0.5d)

If the CSV file must be imported as part of a python program, then for simplicity and efficiency, you could use os.system along the lines suggested by the following:

import os

cmd = """sqlite3 database.db <<< ".import input.csv mytable" """

rc = os.system(cmd)

print(rc)

The point is that by specifying the filename of the database, the data will automatically be saved, assuming there are no errors reading it.

I have build such kind of application using approximatively the same approach except :

• I cache the generated image on the disk and always generate two to three images in advance in a separate thread.
• I don't overlay with a UIImage but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.

Whenever the user start zooming, I acquire the CGPDFPage and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context is like :

CGAffineTransform currentCTM = CGContextGetCTM(context);    
if (currentCTM.a == 1.0 && baseImage) {
    //Calculate ideal scale
    CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
    CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height; 
    CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);

    CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
    CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
    CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
    @synchronized(issue) { 
        CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
        pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
        CGContextConcatCTM(context, pdfToPageTransform);    
        CGContextDrawPDFPage(context, pdfPage);
    }
}

issue is the object containg the CGPDFDocumentRef. I synchronize the part where I access the pdfDoc property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef object do some internal caching that I did not find how to get rid of.

You can try wiht TIMESTAMP(curdate(), curtime()) for use the current time.

Based on Jakub's answer you can configure the following git aliases for convenience:

accept-ours = "!f() { git checkout --ours -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"
accept-theirs = "!f() { git checkout --theirs -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"

They optionally take one or several paths of files to resolve and default to resolving everything under the current directory if none are given.

Add them to the [alias] section of your ~/.gitconfig or run

git config --global alias.accept-ours '!f() { git checkout --ours -- "${@:-.}"; git add -u "${@:-.}"; }; f'
git config --global alias.accept-theirs '!f() { git checkout --theirs -- "${@:-.}"; git add -u "${@:-.}"; }; f'

The answer by Daniel A.A. Pelsmaeker and Yesh analogy is excellent. I would like to add a bit more from hackerrank tutorial. Hope it helps a bit too.

• The depth(or level) of a node is its distance(i.e. no of edges) from tree's root node.
• The height is number of edges between root node and furthest leaf.
• height(node) = 1 + max(height(node.leftSubtree),height(node.rightSubtree)).
  Keep in mind the following points before reading the example ahead.
• Any node has a height of 1.
• Height of empty subtree is -1.
• Height of single element tree or leaf node is 0.
  

Try to target 1024 as the minimum width. Try how it looks at 800, but don't bother too much making that work. At 800x600 almost none of the major websites are going to work, so people working at that resolution are going to have problems all the time anyway.

If you're going to go for a liquid layout, make sure that text doesn't get too wide, because when lines are too long, they become hard to read. That's the main reason why most websites have a fixed width.

When loading the Properties from a Class in the package com.al.common.email.templates you can use

Properties prop = new Properties();
InputStream in = getClass().getResourceAsStream("foo.properties");
prop.load(in);
in.close();

(Add all the necessary exception handling).

If your class is not in that package, you need to aquire the InputStream slightly differently:

InputStream in = 
 getClass().getResourceAsStream("/com/al/common/email/templates/foo.properties");

Relative paths (those without a leading '/') in getResource()/getResourceAsStream() mean that the resource will be searched relative to the directory which represents the package the class is in.

Using java.lang.String.class.getResource("foo.txt") would search for the (inexistent) file /java/lang/String/foo.txt on the classpath.

Using an absolute path (one that starts with '/') means that the current package is ignored.

X * 2 = 1 bit shift left
X / 2 = 1 bit shift right
X * 3 = shift left 1 bit and then add X

If you're doing some performance tuning it's often recommended to set both -XX:PermSize and -XX:MaxPermSize to the same value to increase JVM efficiency.

Here is some information:

1. Support for large page heap on x86 and amd64 platforms
2. Java Support for Large Memory Pages
3. Setting the Permanent Generation Size

You can also specify -XX:+CMSClassUnloadingEnabled to enable class unloading option if you are using CMS GC. It may help to decrease the probability of Java.lang.OutOfMemoryError: PermGen space

define function in .bashrc

function gitall() {
    file=${1:-.}
    comment=${2:-update}
    echo $file
    echo $comment
    git add $file && git commit -m '$comment' && git push origin master
}

in your terminal

gitall

default gitall will add all in current git repo

gitall some-file-to-add 'update file'

will add certain file to change, and use custom commit message

take a list of string as like

List<string> colValListForValidation = new List<string>();

and match string before the task. it will help you bcz all merge cells will have same value

You can use the IFNULL function inside the IF. This will be a little shorter, and there will be fewer repetitions of the field name.

SELECT IF(IFNULL(field1, '') = '', 'empty', field1) AS field1 
FROM tablename

First you should understand how localStorage works. you are doing wrong way to set/get values in local storage. Please read this for more information : How to Use Local Storage with JavaScript

System images are pre-installed Android operating systems, and are only used by emulators. If you use your real Android device for debugging, you no longer need them, so you can remove them all.

The cleanest way to remove them is using SDK Manager. Open up SDK Manager and uncheck those system images and then apply.

Also feel free to remove other components (e.g. old SDK levels) that are of no use.

SCREENSHOT

There is some closure magic happening when passing the callback argument to the addListener method. This can be quite a tricky topic if you are not familiar with how closures work. I would suggest checking out the following Mozilla article for a brief introduction if it is the case:

? Mozilla Dev Center: Working with Closures

You need to escape:

<div class="test">&amp;times</div>

And then read the value using text() to get the unescaped value:

alert($(".test").text()); // outputs: &times

On a high level, if you observe as to where normalization/standardization is mostly used, you will notice that, anytime there is a use of magnitude difference in model building process, it becomes necessary to standardize the inputs so as to ensure that important inputs with small magnitude don't loose their significance midway the model building process.

example:

v(3-1)^2+(1000-900)^2 ˜ v(1000-900)^2

Here, (3-1) contributes hardly a thing to the result and hence the input corresponding to these values is considered futile by the model.

Consider the following:

1. Clustering uses euclidean or, other distance measures.
2. NNs use optimization algorithm to minimise cost function(ex. - MSE).

Both distance measure(Clustering) and cost function(NNs) use magnitude difference in some way and hence standardization ensures that magnitude difference doesn't command over important input parameters and the algorithm works as expected.

#include has nothing to do with projects - it just tells the preprocessor "put the contents of the header file here". If you give it a path that points to the correct location (can be a relative path, like ../your_file.h) it will be included correctly.

You will, however, have to learn about libraries (static/dynamic libraries) in order to make such projects link properly - but that's another question.

If you are dealing with images, use getimagesize. Unlike file_exists, this built-in function supports remote files. It will return an array that contains the image information (width, height, type..etc). All you have to do is to check the first element in the array (the width). use print_r to output the content of the array

$imageArray = getimagesize("http://www.example.com/image.jpg");
if($imageArray[0])
{
    echo "it's an image and here is the image's info<br>";
    print_r($imageArray);
}
else
{
    echo "invalid image";
}

I have came across this issue few times during the development of one complex Excel VBA app. Sometimes Excel started to break VBA object quite randomly. And the only remedy was to reboot machine. After reboot, Excel usually started to act normally.

Soon I have found out that possible solution to this issue is to hit CTRL+Break once when macro is NOT running. Maybe this can help to you too.

I changed windows password today then Tortoise declined to connect me to SVN server. I got around it by opening a Dos box and doing an "svn co ...". It prompted for the new credential then happily did its work. After that, Tortoise works also.

Before mounting external storage BOOT_COMPLETE is sent execute.if your app is installed to external storage it won't receive BOOT_COMPLETE broadcast message. To prevent this you can install your application in internal storage. you can do this just adding this line in menifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:installLocation="internalOnly"
... >

Some HTC devices can enable a "fast boot" feature that is more like a deep hibernation and not a real reboot and therefore should not give the BOOT_COMPLETE intent. To recover this you can add this intent filter inside your receiver:

            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.QUICKBOOT_POWERON" />
            </intent-filter>

You could use one of the below solutions:

$items = Item::whereIn('id', [1,2,..])->get();

or:

$items = DB::table('items')->whereIn('id',[1,2,..])->get();

The following is another method that will work, although as with some of the other methods it will strip decimal places.

a = 1,112
b = a.scan(/\d+/).join().to_i => 1112

this is another simple way to do it .

Name.objects.exclude(alias=None)

To reset a specific file to the last-committed state (to discard uncommitted changes in a specific file):

git checkout thefiletoreset.txt

This is mentioned in the git status output:

(use "git checkout -- <file>..." to discard changes in working directory)

To reset the entire repository to the last committed state:

git reset --hard

To remove untracked files, I usually just delete all files in the working copy (but not the .git/ folder!), then do git reset --hard which leaves it with only committed files.

A better way is to use git clean (warning: using the -x flag as below will cause Git to delete ignored files):

git clean -d -x -f

will remove untracked files, including directories (-d) and files ignored by git (-x). Replace the -f argument with -n to perform a dry-run or -i for interactive mode, and it will tell you what will be removed.

Relevant links:

• git-reset man page
• git-clean man page
• git ready "cleaning up untracked files" (as Marko posted)
• Stack Overflow question "How to remove local (untracked) files from the current Git working tree")

I found the solution. I misplaced the path to the keystore.jks file. Searched for the file on my computer used that path and everything worked great.

jQuery plugin scrollintoview() increases usability

Instead of default DOM implementation you can use a plugin that animates movement and doesn't have any unwanted effects. Here's the simplest way of using it with defaults:

$("yourTargetLiSelector").scrollintoview();

Anyway head over to this blog post where you can read all the details and will eventually get you to GitHub source codeof the plugin.

This plugin automatically searches for the closest scrollable ancestor element and scrolls it so that selected element is inside its visible view port. If the element is already in the view port it doesn't do anything of course.

Short and sweet, no additional modules needed:

my $toDate = `date +%m/%d/%Y" "%l:%M:%S" "%p`;

Output for example would be: 04/25/2017 9:30:33 AM

 if ($("#Password").val() != $("#ConfirmPassword").val()) {
          alert("Passwords do not match.");
      }

A JQuery approach that will eliminate needless code.

Quick and simple, but not good for production:

(in a view)

    request.scheme               # http or https
    request.META['HTTP_HOST']    # example.com
    request.path                 # /some/content/1/

(in a template)

{{ request.scheme }} :// {{ request.META.HTTP_HOST }} {{ request.path }}

Be sure to use a RequestContext, which is the case if you're using render.

Don't trust request.META['HTTP_HOST'] in production: that info comes from the browser. Instead, use @CarlMeyer's answer

When you use find, you have two basic options: filter results out after find has completed searching or use some built in option that will prevent find from considering those files and dirs matching some given pattern.

If you use the former approach on a high number of files and dirs. You will be using a lot of CPU and RAM just to pass the result on to a second process which will in turn filter out results by using a lot of resources as well.

If you use the -not keyword which is a find argument, you will be preventing any path matching the string on the -name or -regex argument behind from being considered, which will be much more efficient.

find . -not -regex ".*/foo/.*" -regex ".*"

Then, any path that is not filtered out by -not will be captured by the subsequent -regex arguments.

For me, the problem was I had two installations of Apache Tomcat

The following steps solved my problem:

1. Open up services.msc in command prompt
2. Select the Apache Tomcat service, right click and select properties
3. Check the path to the executable of the service
4. Follow the instructions in https://stackoverflow.com/questions/7190480/modifying-the-path-to-executable-of-a-windows-service to change the path to "\tomcat\bin\tomcat7.exe" //RS//Tomcat7
5. Restart XAMPP Control Panel

you can achive it with group join

var result = (from c in Customers
          join oi in OrderItems on c.Id equals oi.Order.Customer.Id into g
          Select new { customer = c, orderItems = g});

c is Customer and g is the customers order items.

You can also run exactly same command at Cmd.exe command-line using PowerShell. I'd go with this approach for simplicity...

C:\>PowerShell -Command "temperature | prismcom.exe usb"

Please read up on Understanding the Windows PowerShell Pipeline

You can also type in C:\>PowerShell at the command-line and it'll put you in PS C:\> mode instanctly, where you can directly start writing PS.

$('div[imageId="imageN"]').each(function() {
    // `this` is the div
});

To check for the sole existence of the attribute, no matter which value, you could use ths selector instead: $('div[imageId]')

The Following:

.show-grid [class*="span"] {

means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.

<div class="show-grid">
  <div class="span">.span</div>
  <div class="span6">span6</div>
  <div class="attention-span">attention</div>
  <div class="spanish">spanish</div>
  <div class="mariospan">mariospan</div>
  <div class="espanol">espanol</div>

  <div>
    <div class="span">.span</div>
  </div>

  <p class="span">span</p>
  <span class="span">I do GET HIT</span>

  <span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>

<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>

All of the elements get hit except for the <span> by itself.

In Regards to Bootstrap:

• span6 : this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6 would have a width of 50%.
• In the current day implementation of Bootstrap (v.3 and v.4), you now use the .col-* classes (e.g. col-sm-6), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadays

How about Excel Data Reader?

http://exceldatareader.codeplex.com/

I've used in it anger, in a production environment, to pull large amounts of data from a variety of Excel files into SQL Server Compact. It works very well and it's rather robust.

If you define your array in properties file like:

base.module.elementToSearch=1,2,3,4,5,6

You can load such array in your Java class like this:

  @Value("${base.module.elementToSearch}")
  private String[] elementToSearch;

For the case where there are 2 getters for the same property, the deserializer fails Refer Link

You only need to use LoadLibrary if you want to late bind and only resolve the imported functions at runtime. The easiest way to use a third party dll is to link against a .lib.

In reply to your edit:

Yes, the third party API should consist of a dll and/or a lib that contain the implementation and header files that declares the required types. You need to know the type definitions whichever method you use - for LoadLibrary you'll need to define function pointers, so you could just as easily write your own header file instead. Basically, you only need to use LoadLibrary if you want late binding. One valid reason for this would be if you aren't sure if the dll will be available on the target PC.

In case you want to write fallback code, decoding from base64 has been present in iOS since the very beginning by caveat of NSURL:

NSURL *URL = [NSURL URLWithString:
      [NSString stringWithFormat:@"data:application/octet-stream;base64,%@",
           base64String]];

return [NSData dataWithContentsOfURL:URL];

These snippets all perform exactly the same thing:

element.on('click', function () { ... });
element.bind('click', function () { ... });
element.click(function () { ... });

However, they are very different from these, which all perform the same thing:

element.on('click', 'selector', function () { ... });
element.delegate('click', 'selector', function () { ... });
$('selector').live('click', function () { ... });

The second set of event handlers use event delegation and will work for dynamically added elements. Event handlers that use delegation are also much more performant. The first set will not work for dynamically added elements, and are much worse for performance.

jQuery's on() function does not introduce any new functionality that did not already exist, it is just an attempt to standardize event handling in jQuery (you no longer have to decide between live, bind, or delegate).

Simply in SASS:

.some_class{
     // styles...

     &.active {
       pointer-events:none;
     }
}

private <A, B> Map<B, A> invertMap(Map<A, B> map) {
    Map<B, A> reverseMap = new HashMap<>();
    for (Map.Entry<A, B> entry : map.entrySet()) {
        reverseMap.put(entry.getValue(), entry.getKey());
    }
    return reverseMap;
}

It's important to remember that put replaces the value when called with the same key. So if you map has two keys with the same value only one of them will exist in the inverted map.

this works

If you want to paste some clipboard content at the end of the file type:

Wikipedia points out that the syntax of an IPv6 address includes colons and has a short form preventing fixed-length parsing, and therefore you have to delimit the address portion with []. This completely avoids the odd parsing errors.
