This may not be the best solution. I changed my maven from 3.3.x to 3.2.x. And this issue gone.

You can also use the interface builder to create these effects easily for simple situations. Since the z-values of the views will depend on the order they are listed in the Document Outline, you can drag a UIVisualEffectView onto the document outline before the view you want to blur. This automatically creates a nested UIView, which is the contentView property of the given UIVisualEffectView. Nest things within this view that you want to appear on top of the blur.

You can also easily take advantage of the vibrancy UIVisualEffect, which will automatically create another nested UIVisualEffectView in the document outline with vibrancy enabled by default. You can then add a label or text view to the nested UIView (again, the contentView property of the UIVisualEffectView), to achieve the same effect that the "> slide to unlock" UI element.

You can create an extension for UIView to access these values in the design editor

extension UIView{

    @IBInspectable var shadowOffset: CGSize{
        get{
            return self.layer.shadowOffset
        }
        set{
            self.layer.shadowOffset = newValue
        }
    }

    @IBInspectable var shadowColor: UIColor{
        get{
            return UIColor(cgColor: self.layer.shadowColor!)
        }
        set{
            self.layer.shadowColor = newValue.cgColor
        }
    }

    @IBInspectable var shadowRadius: CGFloat{
        get{
            return self.layer.shadowRadius
        }
        set{
            self.layer.shadowRadius = newValue
        }
    }

    @IBInspectable var shadowOpacity: Float{
        get{
            return self.layer.shadowOpacity
        }
        set{
            self.layer.shadowOpacity = newValue
        }
    }
}

Neither of the posted answers worked for me. Setting position: absolute for the child element did work however.

Here are custom icons with the updated "visual refresh" style that you can generate quickly via a simple .vbs script. I also included a large pre-generated set that you can use immediately with multiple color options: https://github.com/Concept211/Google-Maps-Markers

Use the following format when linking to the GitHub-hosted image files:

https://raw.githubusercontent.com/Concept211/Google-Maps-Markers/master/images/marker_[color][character].png

color
red, black, blue, green, grey, orange, purple, white, yellow

character
A-Z, 1-100, !, @, $, +, -, =, (%23 = #), (%25 = %), (%26 = &), (blank = •)

Examples:

I just thought that I'd add that there is a notion of Z-order in Swing, see [java.awt.Component#setComponentZOrder][1]

which affects the positions of a component in its parents component array, which determines the painting order.

Note that you should override javax.swing.JComponent#isOptimizedDrawingEnabled to return false in the parent container to get your overlapping components to repaint correctly, otherwise their repaints will clobber each other. (JComponents assume no overlapping children unless isOptimizedDrawingEnabled returns false)

[1]: http://java.sun.com/j2se/1.5.0/docs/api/java/awt/Container.html#setComponentZOrder(java.awt.Component, int)

window.open('http://somelocation.com','mywin','width=500,height=500');

OK, here are the things that come into mind:

• Your WCF service presumably running on IIS must be running under the security context that has the privilege that calls the Web Service. You need to make sure in the app pool with a user that is a domain user - ideally a dedicated user.
• You can not use impersonation to use user's security token to pass back to ASMX using impersonation since my WCF web service calls another ASMX web service, installed on a **different** web server
• Try changing Ntlm to Windows and test again.

OK, a few words on impersonation. Basically it is a known issue that you cannot use the impersonation tokens that you got to one server, to pass to another server. The reason seems to be that the token is a kind of a hash using user's password and valid for the machine generated from so it cannot be used from the middle server.

UPDATE

Delegation is possible under WCF (i.e. forwarding impersonation from a server to another server). Look at this topic here.

I was not able to install cv2 on Anaconda-Jupyter notebook running on Ubuntu on Google Cloud Platform. But I found a way to do it as follows:

Run the following command from the ssh terminal and follow the instruction:

 sudo apt-get install libsm6 libxrender1 libfontconfig1

Once its installed Open the Jupyter notebook and run following command:

!pip install opencv-contrib-python

Note: I tried to run this command: "sudo python3 -m pip install opencv-contrib-python"but it was showing an error. But above command worked for me.

Now refresh the notebook page and check whether it's installed or not by running import cv2 in the notebook.

Yes. I'm sure you can do this the same way you can swap two numbers without using a third. Simply cast the pointers to a int/long and perform the XOR operation a couple of times. This is one of those C tricks that makes for a fun question, but doesn't have any practical value.

Can you reduce the O(n) complexity? No, not really. Just use a doubly linked list if you think you are going to need the reverse order.

A cleaner alternative would be to use a Dictionary to handle parameters. They are key-value pairs after all.

private static readonly HttpClient httpclient;

static MyClassName()
{
    // HttpClient is intended to be instantiated once and re-used throughout the life of an application. 
    // Instantiating an HttpClient class for every request will exhaust the number of sockets available under heavy loads. 
    // This will result in SocketException errors.
    // https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=netframework-4.7.1
    httpclient = new HttpClient();    
} 

var url = "http://myserver/method";
var parameters = new Dictionary<string, string> { { "param1", "1" }, { "param2", "2" } };
var encodedContent = new FormUrlEncodedContent (parameters);

var response = await httpclient.PostAsync (url, encodedContent).ConfigureAwait (false);
if (response.StatusCode == HttpStatusCode.OK) {
    // Do something with response. Example get content:
    // var responseContent = await response.Content.ReadAsStringAsync ().ConfigureAwait (false);
}

Also dont forget to Dispose() httpclient, if you dont use the keyword using

As stated in the Remarks section of the HttpClient class in the Microsoft docs, HttpClient should be instantiated once and re-used.

Edit:

You may want to look into response.EnsureSuccessStatusCode(); instead of if (response.StatusCode == HttpStatusCode.OK).

You may want to keep your httpclient and dont Dispose() it. See: Do HttpClient and HttpClientHandler have to be disposed?

Edit:

Do not worry about using .ConfigureAwait(false) in .NET Core. For more details look at https://blog.stephencleary.com/2017/03/aspnetcore-synchronization-context.html

If checkout master was the last thing you did, then the reflog entry HEAD@{1} will contain your commits (otherwise use git reflog or git log -p to find them). Use git merge HEAD@{1} to fast forward them into master.

EDIT:

As noted in the comments, Git Ready has a great article on this.

git reflog and git reflog --all will give you the commit hashes of the mis-placed commits.

var string = 123 (is string),

parseInt(parameter is string);

var string = '123';

var int= parseInt(string );

console.log(int);  //Output will be 123.

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

If you don't remember the password you set for root and need to reset it, follow these steps:

1. Stop the mysqld server, this varies per install
2. Run the server in safe mode with privilege bypass

sudo mysqld_safe --skip-grant-tables;

3. In a new window connect to the database, set a new password and flush the permissions & quit:

mysql -u root

For MySQL older than MySQL 5.7 use:

UPDATE mysql.user SET Password=PASSWORD('your-password') WHERE User='root';

For MySQL 5.7+ use:

USE mysql;

UPDATE mysql.user SET authentication_string=PASSWORD("your-password") WHERE User='root';

Refresh and quit:

FLUSH PRIVILEGES;

\q

4. Stop the safe mode server and start your regular server back. The new password should work now. Worked like a charm for me :)

for example you want to add rows of variable 2 to variable 1 of a data named "edges" just do it like this

allEdges <- data.frame(c(edges$V1,edges$V2))

This is most definitely a programming problem. The problem is that it cannot be programmed, per se. When P is actually zero then the concept of percentage change has no meaning. Zero to anything cannot be expressed as a rate as it is outside the definition boundary of rate. Going from 'not being' into 'being' is not a change of being, it is instead creation of being.

The Activator.CreateInstance method creates an instance of a specified type using the constructor that best matches the specified parameters.

For example, let's say that you have the type name as a string, and you want to use the string to create an instance of that type. You could use Activator.CreateInstance for this:

string objTypeName = "Foo";
Foo foo = (Foo)Activator.CreateInstance(Type.GetType(objTypeName));

Here's an MSDN article that explains it's application in more detail:

http://msdn.microsoft.com/en-us/library/wccyzw83.aspx

For those who need convert minutes to time with more than 24h format:

DECLARE @minutes int = 7830
SELECT CAST(@minutes / 60 AS VARCHAR(8)) + ':' + FORMAT(@minutes % 60, 'D2') AS [Time]

Result:

130:30

You have to explicitly set the position of the parent container along with the position of the child container. The typical way to do that is something like this:

div.parent{
    position: relative;
    left: 0px;  /* stick it wherever it was positioned by default */
    top: 0px;
}

div.child{
    position: absolute;
    left: 10px;
    top: 10px;
}

Besides grep, you can also use other utilities such as awk or sed

Here is a few examples. Let say you want to search for a string is in the file named GPL.

Your sample file

user@linux:~$ cat -n GPL 
     1    The GNU General Public License is a free, copyleft license for
     2    The licenses for most software and other practical works are designed
     3  the GNU General Public License is intended to guarantee your freedom to
     4  GNU General Public License for most of our software;
user@linux:~$ 

1. grep

user@linux:~$ grep is GPL 
  The GNU General Public License is a free, copyleft license for
the GNU General Public License is intended to guarantee your freedom to
user@linux:~$ 

2. awk

user@linux:~$ awk /is/ GPL 
  The GNU General Public License is a free, copyleft license for
the GNU General Public License is intended to guarantee your freedom to
user@linux:~$ 

3. sed

user@linux:~$ sed -n '/is/p' GPL
  The GNU General Public License is a free, copyleft license for
the GNU General Public License is intended to guarantee your freedom to
user@linux:~$ 

Hope this helps

C++0x FAQ by BS

Angular adds this to keep track of your changes, so it knows when it needs to update the DOM.

If you use angular.toJson(obj) instead of JSON.stringify(obj) then Angular will strip out these internal-use values for you.

Also, if you change your repeat expression to use the track by {uniqueProperty} suffix, Angular won't have to add $$hashKey at all. For example

<ul>
    <li ng-repeat="link in navLinks track by link.href">
        <a ng-href="link.href">{{link.title}}</a>
    </li>
</ul>

Just always remember you need the "link." part of the expression - I always tend to forget that. Just track by href will surely not work.

Did you try PURE ?
If you give it a try, feel free to post any trouble you may face at the forum

While it was primarly designed for the browser, it works well with Jaxer and Rhino.

I don't know node.js yet but if you can cache some JS and functions in memory, the speed should be even more impressive.

Laravel - htmlspecialchars() expects parameter 1 to be string, object given.

thank me latter.........................

when you send or get array from contrller or function but try to print as single value or single variable in laravel blade file so it throws an error

->use any think who convert array into string it work.

solution: 1)run the foreach loop and get single single value and print. 2)The implode() function returns a string from the elements of an array. {{ implode($your_variable,',') }}

implode is best way to do it and its 100% work.

Thanks guys. All above failed except this that deleted all content from the file C:\Users\debasish\workspace\.metadata\.plugins\org.eclipse.wst.server.core then creating server again.

But delete server first before deleting those file contents.

A new method has been added with Java 8 to do just that.

import static java.lang.Math.toIntExact;

long foo = 10L;
int bar = toIntExact(foo);

Will throw an ArithmeticException in case of overflow.

See: Math.toIntExact(long)

Several other overflow safe methods have been added to Java 8. They end with exact.

Examples:

• Math.incrementExact(long)
• Math.subtractExact(long, long)
• Math.decrementExact(long)
• Math.negateExact(long),
• Math.subtractExact(int, int)

Well.. Apparently the file does not exist or cannot be found. Try using a full path. You're probably reading from the wrong directory when you don't specify the path, unless a.txt is in your current working directory.

You just need to remove the parenthesis:

addContact(entityId, refreshContactList);

This then passes the function without executing it first.

Here is an example:

function addContact(id, refreshCallback) {
    refreshCallback();
    // You can also pass arguments if you need to
    // refreshCallback(id);
}

function refreshContactList() {
    alert('Hello World');
}

addContact(1, refreshContactList);

Using Click:

Click is a library for command-line interfaces and it provides functionality for asking a valid response from a user.

Simple example:

import click

number = click.prompt('Please enter a number', type=float)
print(number)

Please enter a number: 
 a
Error: a is not a valid floating point value
Please enter a number: 
 10
10.0

Note how it converted the string value to a float automatically.

Checking if a value is within a range:

There are different custom types provided. To get a number in a specific range we can use IntRange:

age = click.prompt("What's your age?", type=click.IntRange(1, 120))
print(age)

What's your age?: 
 a
Error: a is not a valid integer
What's your age?: 
 0
Error: 0 is not in the valid range of 1 to 120.
What's your age?: 
 5
5

We can also specify just one of the limits, min or max:

age = click.prompt("What's your age?", type=click.IntRange(min=14))
print(age)

What's your age?: 
 0
Error: 0 is smaller than the minimum valid value 14.
What's your age?: 
 18
18

Membership testing:

Using click.Choice type. By default this check is case-sensitive.

choices = {'apple', 'orange', 'peach'}
choice = click.prompt('Provide a fruit', type=click.Choice(choices, case_sensitive=False))
print(choice)

Provide a fruit (apple, peach, orange): 
 banana
Error: invalid choice: banana. (choose from apple, peach, orange)
Provide a fruit (apple, peach, orange): 
 OrAnGe
orange

Working with paths and files:

Using a click.Path type we can check for existing paths and also resolve them:

path = click.prompt('Provide path', type=click.Path(exists=True, resolve_path=True))
print(path)

Provide path: 
 nonexistent
Error: Path "nonexistent" does not exist.
Provide path: 
 existing_folder
'/path/to/existing_folder

Reading and writing files can be done by click.File:

file = click.prompt('In which file to write data?', type=click.File('w'))
with file.open():
    file.write('Hello!')
# More info about `lazy=True` at:
# https://click.palletsprojects.com/en/7.x/arguments/#file-opening-safety
file = click.prompt('Which file you wanna read?', type=click.File(lazy=True))
with file.open():
    print(file.read())

In which file to write data?: 
         # <-- provided an empty string, which is an illegal name for a file
In which file to write data?: 
 some_file.txt
Which file you wanna read?: 
 nonexistent.txt
Error: Could not open file: nonexistent.txt: No such file or directory
Which file you wanna read?: 
 some_file.txt
Hello!

Other examples:

Password confirmation:

password = click.prompt('Enter password', hide_input=True, confirmation_prompt=True)
print(password)

Enter password: 
 ······
Repeat for confirmation: 
 ·
Error: the two entered values do not match
Enter password: 
 ······
Repeat for confirmation: 
 ······
qwerty

Default values:

In this case, simply pressing Enter (or whatever key you use) without entering a value, will give you a default one:

number = click.prompt('Please enter a number', type=int, default=42)
print(number)

Please enter a number [42]: 
 a
Error: a is not a valid integer
Please enter a number [42]: 
 
42

And please, whatever you do, configure the listings package to use fixed-width font (as in your example; you'll find the option in the documentation). Default setting uses proportional font typeset on a grid, which is, IMHO, incredibly ugly and unreadable, as can be seen from the other answers with pictures. I am personally very irritated when I must read some code typeset in a proportional font.

Try setting fixed-width font with this:

\lstset{basicstyle=\ttfamily}

To get the device id, connect your phone to USB and open logcat in android studio Use the code below (make sure you have USB debugging enabled in your device). Then open any app (download any random app from play store) which has google Ad. In the Logcat type "set" as shown in the image. Your device id is shown highlighted in the image as

setTestDeviceIds(Arrays.asList("CC9DW7W7R4H0NM3LT9OLOF7455F8800D")).

Use the Test Device in your code as shown

val adRequest = AdRequest
        .Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("CC9DW7W7R4H0NM3LT9OLOF7455F8800D")
        .build()

It looks like you don't have any records that match your query, so you'd want to return an empty array (or null or something) if the number of rows == 0.

Have a look at the following

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

your controller should have action method which would accept HttpPostedFileBase;

 public ActionResult FileUpload(HttpPostedFileBase file)
    {
        if (file != null)
        {
            string pic = System.IO.Path.GetFileName(file.FileName);
            string path = System.IO.Path.Combine(
                                   Server.MapPath("~/images/profile"), pic); 
            // file is uploaded
            file.SaveAs(path);

            // save the image path path to the database or you can send image 
            // directly to database
            // in-case if you want to store byte[] ie. for DB
            using (MemoryStream ms = new MemoryStream()) 
            {
                 file.InputStream.CopyTo(ms);
                 byte[] array = ms.GetBuffer();
            }

        }
        // after successfully uploading redirect the user
        return RedirectToAction("actionname", "controller name");
    }

Update 1

In case you want to upload files using jQuery with asynchornously, then try this article.

the code to handle the server side (for multiple upload) is;

 try
    {
        HttpFileCollection hfc = HttpContext.Current.Request.Files;
        string path = "/content/files/contact/";

        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            if (hpf.ContentLength > 0)
            {
                string fileName = "";
                if (Request.Browser.Browser == "IE")
                {
                    fileName = Path.GetFileName(hpf.FileName);
                }
                else
                {
                    fileName = hpf.FileName;
                }
                string fullPathWithFileName = path + fileName;
                hpf.SaveAs(Server.MapPath(fullPathWithFileName));
            }
        }

    }
    catch (Exception ex)
    {
        throw ex;
    }

this control also return image name (in a javascript call back) which then you can use it to display image in the DOM.

UPDATE 2

Alternatively, you can try Async File Uploads in MVC 4.

class Countries < ActiveRecord::Base
    self.table_name = "cc"
end

In Rails 3.x this is the way to specify the table name.

Another simple solution without the TortoiseSVN overhead is RapidSVN. It is a lightweight open-source SVN client that is easy to install and easy to use.

The Download SVN tool did also work quite well, but it had problems with SVN repositories that don't provide a web interface. RapidSVN works fine with those.

Use :

<EditText
    ..     
    android:drawableStart="@drawable/icon" />

I tried using the local IP address to connect as well as a public one. I've tried:

Yes, the site can communicate with the server Named pipes/TCP is enabled. Remote connections are allowed. Windows Firewall is off Created an exception for port 1433 in Windows Firewall. Enabled everything in SQL Server Configuration Manager.

i ensured and did the above as well and I just want to share that the DOUBLE BACKSLASH

oBuilder.DataSource = "SPECIFICPCNAME\SQLEXPRESS";

Using a SINGLE BACKSLASH resulted into a build error i.e.: Error 1 Unrecognized escape sequence

I hope this helps the next guy - I've sacrificed dinner, midnight snack and NBA highlights time solving this (shame)

Thanks to [Tamizh venthan] ^_^

try this. It will solve your problem.

 var lastDayOfMonth = DateTime.DaysInMonth(int.Parse(ddlyear.SelectedValue), int.Parse(ddlmonth.SelectedValue));
DateTime tLastDayMonth = Convert.ToDateTime(lastDayOfMonth.ToString() + "/" + ddlmonth.SelectedValue + "/" + ddlyear.SelectedValue);

In windows download the node executable file from the website and install it. this worked for me.

If you are parsing string data from the console or similar, the best way is to use regular expressions. Read more on that here: http://java.sun.com/developer/technicalArticles/releases/1.4regex/

Otherwise, to parse an int from a string, try Integer.parseInt(string). If the string is not a number, you will get an exception. Otherise you can then perform your checks on that value to make sure it is not negative.

String input;
int number;
try
{
    number = Integer.parseInt(input);
    if(number > 0)
    {
        System.out.println("You positive number is " + number);
    }
} catch (NumberFormatException ex)
{
     System.out.println("That is not a positive number!");
}

To get a character-only string, you would probably be better of looping over each character checking for digits, using for instance Character.isLetter(char).

String input
for(int i = 0; i<input.length(); i++)
{
   if(!Character.isLetter(input.charAt(i)))
   {
      System.out.println("This string does not contain only letters!");
      break;
   }
}

Good luck!

Use boost::filesystem. It will be incorporated into the next standard anyway so you may as well get used to it.

allesklar: That is slightly misleading, as scripts and bots can POST data nearly as easily as sending a normal request. It's not a secret, it's part of HTTP.

Vin's answer worked great for me. Here is the same solution for C# developers using Xamarin.iOS/MonoTouch:

var navigationBar = NavigationController.NavigationBar; //or another reference
navigationBar.BarTintColor = UIColor.Blue;
navigationBar.TintColor = UIColor.White;
navigationBar.SetTitleTextAttributes(new UITextAttributes() { TextColor = UIColor.White });
navigationBar.Translucent = false;

Step 1

Download the mongodb

Step 2

• Follow normal setup instructions

Step 3

• Create the following folder

C:\data\db

Step 4

• cd to C:\Program Files\MongoDB\Server\3.2\bin>
• enter command mongod
• by default, mongodb server will start at port 27017

Step 5

• (optionally) download RoboMongo and follow normal setup instructions

Step 6

• Start RoboMongo and create a new connection on localhost:27017

Your MongoDB is started and connected with RoboMongo (now Robo 3T) - a third party GUI tool

You might also find it useful to know generally what these data types are used for:

• :string - is for small data types such as a title. (Should you choose string or text?)
• :text - is for longer pieces of textual data, such as a paragraph of information
• :binary - is for storing data such as images, audio, or movies.
• :boolean - is for storing true or false values.
• :date - store only the date
• :datetime - store the date and time into a column.
• :time - is for time only
• :timestamp - for storing date and time into a column.(What's the difference between datetime and timestamp?)
• :decimal - is for decimals (example of how to use decimals).
• :float - is for decimals. (What's the difference between decimal and float?)
• :integer - is for whole numbers.
• :primary_key - unique key that can uniquely identify each row in a table

There's also references used to create associations. But, I'm not sure this is an actual data type.

New Rails 4 datatypes available in PostgreSQL:

• :hstore - storing key/value pairs within a single value (learn more about this new data type)
• :array - an arrangement of numbers or strings in a particular row (learn more about it and see examples)
• :cidr_address - used for IPv4 or IPv6 host addresses
• :inet_address - used for IPv4 or IPv6 host addresses, same as cidr_address but it also accepts values with nonzero bits to the right of the netmask
• :mac_address - used for MAC host addresses

Learn more about the address datatypes here and here.

Also, here's the official guide on migrations: http://edgeguides.rubyonrails.org/migrations.html

This problem mainly occurs when we are trying to save or update the object which are already fetched into memory by a running session. If you've fetched object from the session and you're trying to update in the database, then this exception may be thrown.

I used session.evict(); to remove the cache stored in hibernate first or if you don't wanna take risk of loosing data, better you make another object for storing the data temp.

     try
    {
        if(!session.isOpen())
        {
            session=EmployeyDao.getSessionFactory().openSession();
        }
            tx=session.beginTransaction();

        session.evict(e);
        session.saveOrUpdate(e);
        tx.commit();;
        EmployeyDao.shutDown(session);
    }
    catch(HibernateException exc)
    {
        exc.printStackTrace();
        tx.rollback();
    }

I updated BigGridDemo to support multiple sheets.

To resolve external dependencies within project. below things are important..
1. The compiler should know that where are header '.h' files located in workspace.
2. The linker able to find all specified  all '.lib' files & there names for current project.

So, Developer has to specify external dependencies for Project as below..

1. Select Project in Solution explorer.

2 . Project Properties -> Configuration Properties -> C/C++ -> General
specify all header files in "Additional Include Directories".

3.  Project Properties -> Configuration Properties -> Linker -> General
specify relative path for all lib files in "Additional Library Directories".

I made this 2 extension methods, this is working really well.

The first answer works very well, but for ZERO / 0 it will format as .00

Hence the format #,##0.00 is working well for me. Always test different numbers such as 0 / 100 / 2334.30 and negative numbers before deploying to production system.

Please try this. This query can be used for date comparison

select * from [User] U where convert(varchar(10),U.DateCreated, 120) = '2014-02-07'

I recommend

$('#myTable > tbody:first').append('<tr>...</tr><tr>...</tr>'); 

as opposed to

$('#myTable > tbody:last').append('<tr>...</tr><tr>...</tr>'); 

The first and last keywords work on the first or last tag to be started, not closed. Therefore, this plays nicer with nested tables, if you don't want the nested table to be changed, but instead add to the overall table. At least, this is what I found.

<table id=myTable>
  <tbody id=first>
    <tr><td>
      <table id=myNestedTable>
        <tbody id=last>
        </tbody>
      </table>
    </td></tr>
  </tbody>
</table>

Symfony is smart and knows how to make the find() by itself :

public function deleteGuestAction(Guest $guest)
{
    if (!$guest) {
        throw $this->createNotFoundException('No guest found');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $em->remove($guest);
    $em->flush();

    return $this->redirect($this->generateUrl('GuestBundle:Page:viewGuests.html.twig'));
}

To send the id in your controller, use {{ path('your_route', {'id': guest.id}) }}

try using -U (aka --update-snapshots) when you run maven

And make sure the dependency definition is correct

parseInt(x) it will cast it into integer

x = parseInt(x);
x = parseInt(x,10); //the radix is 10 (decimal)

parseFloat(x) it will cast it into float

Working Demo Reading more Info

x = parseFloat(x);

you can directly use prompt

var x = parseInt(prompt("Enter a Number", "1"), 10)

Try this.

$sub_total = 0;

and within your loop now you can use this

$sub_total += ($item['quantity'] * $product['price']);

It should solve your problem.

Let's break >> /dev/null 2>&1 statement into parts:

Part 1: >> output redirection

This is used to redirect the program output and append the output at the end of the file. More...

Part 2: /dev/null special file

This is a Pseudo-devices special file.

Command ls -l /dev/null will give you details of this file:

crw-rw-rw-. 1 root root 1, 3 Mar 20 18:37 /dev/null

Did you observe crw? Which means it is a pseudo-device file which is of character-special-file type that provides serial access.

/dev/null accepts and discards all input; produces no output (always returns an end-of-file indication on a read). Reference: Wikipedia

Part 3: 2>&1 file descriptor

Whenever you execute a program, the operating system always opens three files, standard input, standard output, and standard error as we know whenever a file is opened, the operating system (from kernel) returns a non-negative integer called a file descriptor. The file descriptor for these files are 0, 1, and 2, respectively.

So 2>&1 simply says redirect standard error to standard output.

& means whatever follows is a file descriptor, not a filename.

In short, by using this command you are telling your program not to shout while executing.

What is the importance of using 2>&1?

If you don't want to produce any output, even in case of some error produced in the terminal. To explain more clearly, let's consider the following example:

$ ls -l > /dev/null

For the above command, no output was printed in the terminal, but what if this command produces an error:

$ ls -l file_doesnot_exists > /dev/null
ls: cannot access file_doesnot_exists: No such file or directory

Despite I'm redirecting output to /dev/null, it is printed in the terminal. It is because we are not redirecting error output to /dev/null, so in order to redirect error output as well, it is required to add 2>&1:

$ ls -l file_doesnot_exists > /dev/null 2>&1

If you would like to indent text within a div without changing the size of the div use the CSS text-indent instead of padding-left.

.indent {_x000D_
  text-indent: 1em;_x000D_
}_x000D_
.border {_x000D_
  border-style: solid;_x000D_
}

<div class="border">_x000D_
  Non indented_x000D_
</div>_x000D_
_x000D_
<br>_x000D_
_x000D_
<div class="border indent">_x000D_
  Indented_x000D_
</div>

I've dealing with a similar scenario for an application developed with Django web web framework and these are the steps that worked perfectly for me:

• content of my Dockerfile

[mlazo@srvjenkins project_textile]$ cat docker/Dockerfile.debug 
FROM malazo/project_textile_ubuntu:latest 

ENV PROJECT_DIR=/proyectos/project_textile PROJECT_NAME=project_textile WRAPPER_PATH=/usr/share/virtualenvwrapper/virtualenvwrapper.sh

COPY . ${PROJECT_DIR}/
WORKDIR ${PROJECT_DIR}

RUN echo "source ${WRAPPER_PATH}" > ~/.bashrc
SHELL ["/bin/bash","-c","-l"]
RUN     mkvirtualenv -p $(which python3) ${PROJECT_NAME} && \
        workon ${PROJECT_NAME} && \
        pip3 install -r requirements.txt 

EXPOSE 8000

ENTRYPOINT ["tests/container_entrypoint.sh"]
CMD ["public/manage.py","runserver","0:8000"]

• content of the ENTRYPOINT file "tests/container_entrypoint.sh":

[mlazo@srvjenkins project_textile]$ cat tests/container_entrypoint.sh
#!/bin/bash
# *-* encoding : UTF-8 *-*
sh tests/deliver_env.sh
source ~/.virtualenvs/project_textile/bin/activate 
exec python "$@"

• finally, the way I deploy the container was :

[mlazo@srvjenkins project_textile]$ cat ./tests/container_deployment.sh 
#!/bin/bash

CONT_NAME="cont_app_server"
IMG_NAME="malazo/project_textile_app"
[ $(docker ps -a |grep -i ${CONT_NAME} |wc -l) -gt 0 ] && docker rm -f ${CONT_NAME}

I really hope this would be helpful for somebody else.

Greetings,

you can remove last comma:

var sentence = "I got,. commas, here,";
sentence = sentence.replace(/(.+),$/, '$1');
console.log(sentence);

There's no fixed time for retransmission. Simple implementations estimate the RTT (round-trip-time) and if no ACK to send data has been received in 2x that time then they re-send.

They then double the wait-time and re-send once more if again there is no reply. Rinse. Repeat.

More sophisticated systems make better estimates of how long it should take for the ACK as well as guesses about exactly which data has been lost.

The bottom-line is that there is no hard-and-fast rule about exactly when to retransmit. It's up to the implementation. All retransmissions are triggered solely by the sender based on lack of response from the receiver.

TCP never drops data so no, there is no way to indicate a server should forget about some segment.

Just use

string.Join(",", yourCollection)

This way you don't need the StringBuilder and the loop.

Long addition about async case. As of 2019, it's not a rare setup when the data are coming asynchronously.

In case your data are in async collection, there is no string.Join overload taking IAsyncEnumerable<T>. But it's easy to create one manually, hacking the code from string.Join:

public static class StringEx
{
    public static async Task<string> JoinAsync<T>(string separator, IAsyncEnumerable<T> seq)
    {
        if (seq == null)
            throw new ArgumentNullException(nameof(seq));

        await using (var en = seq.GetAsyncEnumerator())
        {
            if (!await en.MoveNextAsync())
                return string.Empty;

            string firstString = en.Current?.ToString();

            if (!await en.MoveNextAsync())
                return firstString ?? string.Empty;

            // Null separator and values are handled by the StringBuilder
            var sb = new StringBuilder(256);
            sb.Append(firstString);

            do
            {
                var currentValue = en.Current;
                sb.Append(separator);
                if (currentValue != null)
                    sb.Append(currentValue);
            }
            while (await en.MoveNextAsync());
            return sb.ToString();
        }
    }
}

If the data are coming asynchronously but the interface IAsyncEnumerable<T> is not supported (like the mentioned in comments SqlDataReader), it's relatively easy to wrap the data into an IAsyncEnumerable<T>:

async IAsyncEnumerable<(object first, object second, object product)> ExtractData(
        SqlDataReader reader)
{
    while (await reader.ReadAsync())
        yield return (reader[0], reader[1], reader[2]);
}

and use it:

Task<string> Stringify(SqlDataReader reader) =>
    StringEx.JoinAsync(
        ", ",
        ExtractData(reader).Select(x => $"{x.first} * {x.second} = {x.product}"));

In order to use Select, you'll need to use nuget package System.Interactive.Async. Here you can find a compilable example.

If bringing existing Visual Studio 2015 solution into Visual Studio 2017 and you want to build it with c++17 native compiler, you should first Retarget the solution/projects to v141 , THEN the dropdown will appear as described above ( Configuration Properties -> C/C++ -> Language -> Language Standard)

I was getting this exception not because of AND instead of comma, in fact I was having this exception just because I was not using apostrophes in where clause.

Like my query was

update table set coulmn1='something' where column2 in (00012121);

when I changed where clause to where column2 in ('00012121'); then the query worked fine for me.

Simple, make a simple asp page with the designer (just for the beginning) Lets say the body is something like this:

<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <br />
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </div>
    <p>
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </p>
    </form>
</body>

Great, now every asp object IS an object. So you can access it in the asp's CS code. The asp's CS code is triggered by events (mostly). The class will probably inherit from System.Web.UI.Page

If you go to the cs file of the asp page, you'll see a protected void Page_Load(object sender, EventArgs e) ... That's the load event, you can use that to populate data into your objects when the page loads.

Now, go to the button in your designer (Button1) and look at its properties, you can design it, or add events from there. Just change to the events view, and create a method for the event.

The button is a web control Button Add a Click event to the button call it Button1Click:

void Button1Click(Object sender,EventArgs e) { }

Now when you click the button, this method will be called. Because ASP is object oriented, you can think of the page as the actual class, and the objects will hold the actual current data.

So if for example you want to access the text in TextBox1 you just need to call that object in the C# code:

String firstBox = TextBox1.Text;

In the same way you can populate the objects when event occur.

Now that you have the data the user posted in the textboxes , you can use regular C# SQL connections to add the data to your database.

I think you have to be precise with which version you want to link with the command brew link python like:

brew link python 3

It will give you an error like that:

Linking /usr/local/Cellar/python3/3.5.2... 
Error: Could not symlink bin/2to3-3.5
Target /usr/local/bin/2to3-3.5
already exists. 

You may want to remove it:

rm '/usr/local/bin/2to3-3.5'

To force the link and overwrite all conflicting files:

brew link --overwrite python3

To list all files that would be deleted:

brew link --overwrite --dry-run python3

but you have to copy/paste the command to force the link which is:

brew link --overwrite python3

I think that you must have the version (the newer) installed.

A sha256 is 256 bits long -- as its name indicates.

Since sha256 returns a hexadecimal representation, 4 bits are enough to encode each character (instead of 8, like for ASCII), so 256 bits would represent 64 hex characters, therefore you need a varchar(64), or even a char(64), as the length is always the same, not varying at all.

And the demo :

$hash = hash('sha256', 'hello, world!');
var_dump($hash);

Will give you :

$ php temp.php
string(64) "68e656b251e67e8358bef8483ab0d51c6619f3e7a1a9f0e75838d41ff368f728"

i.e. a string with 64 characters.

I had to make the following changes for the popover to position below with some overlap and to show the arrow correctly.

js

case 'bottom-right':  
    tp = {top: pos.top + pos.height + 10, left: pos.left + pos.width - 40}  
    break  

css

    .popover.bottom-right .arrow {  
      left: 20px; /* MODIFIED */  
      margin-left: -11px;  
      border-top-width: 0;  
      border-bottom-color: #999;  
      border-bottom-color: rgba(0, 0, 0, 0.25);  
      top: -11px;  
    }  
    .popover.bottom-right .arrow:after {  
      top: 1px;  
      margin-left: -10px;  
      border-top-width: 0;  
      border-bottom-color: #ffffff;  
    }  

This can be extended for arrow locations elsewhere .. enjoy!

Slightly off-topic to your question, but it's probably worth mentioning anyway:

Commons Lang has got some excellent methods you can use in overriding equals and hashcode. Check out EqualsBuilder.reflectionEquals(...) and HashCodeBuilder.reflectionHashCode(...). Saved me plenty of headache in the past - although of course if you just want to do "equals" on ID it may not fit your circumstances.

I also agree that you should use the @Override annotation whenever you're overriding equals (or any other method).

You can use Load function

Load TableName fullfilepath; 

You're running bundle exec on a program. The program's creators wrote it when certain versions of gems were available. The program Gemfile specifies the versions of the gems the creators decided to use. That is, the script was made to run correctly against these gem versions.

Your system-wide Gemfile may differ from this Gemfile. You may have newer or older gems with which this script doesn't play nice. This difference in versions can give you weird errors.

bundle exec helps you avoid these errors. It executes the script using the gems specified in the script's Gemfile rather than the systemwide Gemfile. It executes the certain gem versions with the magic of shell aliases.

See more on the man page.

Here's an example Gemfile:

source 'http://rubygems.org'

gem 'rails', '2.8.3'

Here, bundle exec would execute the script using rails version 2.8.3 and not some other version you may have installed system-wide.

Use FractionallySizedBox widget.

FractionallySizedBox(
  widthFactor: 1.0, // width w.r.t to parent
  heightFactor: 1.0,  // height w.r.t to parent
  child: *Your Child Here*
}

This widget is also very useful when you want to size your child at a fractional of its parent's size.

Example:

If you want the child to occupy 50% width of its parent, provide widthFactor as 0.5

Please use this. You will get table names along with schema names:

SELECT SYSSCHEMA.NAME, SYSTABLE.NAME
FROM SYS.tables SYSTABLE
INNER JOIN SYS.SCHEMAS SYSSCHEMA
ON SYSTABLE.SCHEMA_ID = SYSSCHEMA.SCHEMA_ID

This should work...

JavaScriptSerializer ser = new JavaScriptSerializer();
var records = new ser.Deserialize<List<Record>>(jsonData);

public class Person
{
    public string Name;
    public int Age;
    public string Location;
}
public class Record
{
    public Person record;
}

Old question, but since the question asks "using jQuery", I thought I'd provide an option that lets you do this without introducing any vendor dependency.

While there are a lot of templating engines out there, many of their features have fallen in to disfavour recently, with iteration (<% for), conditionals (<% if) and transforms (<%= myString | uppercase %>) seen as microlanguage at best, and anti-patterns at worst. Modern templating practices encourage simply mapping an object to its DOM (or other) representation, e.g. what we see with properties mapped to components in ReactJS (especially stateless components).

Templates Inside HTML

One property you can rely on for keeping the HTML for your template next to the rest of your HTML, is by using a non-executing <script> type, e.g. <script type="text/template">. For your case:

<script type="text/template" data-template="listitem">
    <a href="${url}" class="list-group-item">
        <table>
            <tr>
                <td><img src="${img}"></td>
                <td><p class="list-group-item-text">${title}</p></td>
            </tr>
        </table>
    </a>
</script>

On document load, read your template and tokenize it using a simple String#split

var itemTpl = $('script[data-template="listitem"]').text().split(/\$\{(.+?)\}/g);

Notice that with our token, you get it in the alternating [text, property, text, property] format. This lets us nicely map it using an Array#map, with a mapping function:

function render(props) {
  return function(tok, i) { return (i % 2) ? props[tok] : tok; };
}

Where props could look like { url: 'http://foo.com', img: '/images/bar.png', title: 'Lorem Ipsum' }.

Putting it all together assuming you've parsed and loaded your itemTpl as above, and you have an items array in-scope:

$('.search').keyup(function () {
  $('.list-items').append(items.map(function (item) {
    return itemTpl.map(render(item)).join('');
  }));
});

This approach is also only just barely jQuery - you should be able to take the same approach using vanilla javascript with document.querySelector and .innerHTML.

jsfiddle

Templates inside JS

A question to ask yourself is: do you really want/need to define templates as HTML files? You can always componentize + re-use a template the same way you'd re-use most things you want to repeat: with a function.

In es7-land, using destructuring, template strings, and arrow-functions, you can write downright pretty looking component functions that can be easily loaded using the $.fn.html method above.

const Item = ({ url, img, title }) => `
  <a href="${url}" class="list-group-item">
    <div class="image">
      <img src="${img}" />
    </div>
    <p class="list-group-item-text">${title}</p>
  </a>
`;

Then you could easily render it, even mapped from an array, like so:

$('.list-items').html([
  { url: '/foo', img: 'foo.png', title: 'Foo item' },
  { url: '/bar', img: 'bar.png', title: 'Bar item' },
].map(Item).join(''));

Oh and final note: don't forget to sanitize your properties passed to a template, if they're read from a DB, or someone could pass in HTML (and then run scripts, etc.) from your page.

Use PowerManager.WakeLock class inorder to perform this. See the following code:

import android.os.PowerManager;

public class MyActivity extends Activity {

    protected PowerManager.WakeLock mWakeLock;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(final Bundle icicle) {
        setContentView(R.layout.main);

        /* This code together with the one in onDestroy() 
         * will make the screen be always on until this Activity gets destroyed. */
        final PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
        this.mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
        this.mWakeLock.acquire();
    }

    @Override
    public void onDestroy() {
        this.mWakeLock.release();
        super.onDestroy();
    }
}

Use the follwing permission in manifest file :

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

Hope this will solve your problem...:)

This is the way Visual Studio is designed: One solution, one Visual Studio (VS) instance.

Besides switching between solutions in one VS instance, you can also open another VS instance and open your other solution with that one. Next to solutions there are as you said "projects". You can have multiple projects within one solution and therefore view many projects at the same time.

I had a similar problem where the SelectedItem-binding did not update when I selected something in the combobox. My problem was that I had to set UpdateSourceTrigger=PropertyChanged for the binding.

<ComboBox ItemsSource="{Binding SalesPeriods}" 
          SelectedItem="{Binding SelectedItem, UpdateSourceTrigger=PropertyChanged}" />

You can drop the database and then recreate it with the below:-

mysql> drop database [database name];
mysql> create database [database name];

Pick one or more from:

• Your application isn't successfully listening on the intended IP:PORT
  • Because you haven't configured it successfully
  • Because the user doesn't have permission to
• Your application is listening successfully on the intended IP:PORT, but clients can't reach it because
  • The server local iptables prevents it.
  • A firewall prevents it.

So, you can check that your application is listening successfully by running lsof -i as root on the machine and look for a python entry with the corresponding port you've specified.

Non-root users generally cannot bind to ports < 1024.

You'll need to look at iptables -nvL to see if there's a rule that would prevent access to the ip:port that you are trying to bind your application to.

If there is an upstream firewall and you don't know much about it, you'll need to talk to your network administrators.

You should use Array.reduce for this.

var options = [_x000D_
  { name: 'One', assigned: true }, _x000D_
  { name: 'Two', assigned: false }, _x000D_
  { name: 'Three', assigned: true }, _x000D_
];_x000D_
_x000D_
var reduced = options.reduce(function(filtered, option) {_x000D_
  if (option.assigned) {_x000D_
     var someNewValue = { name: option.name, newProperty: 'Foo' }_x000D_
     filtered.push(someNewValue);_x000D_
  }_x000D_
  return filtered;_x000D_
}, []);_x000D_
_x000D_
document.getElementById('output').innerHTML = JSON.stringify(reduced);

<h1>Only assigned options</h1>_x000D_
<pre id="output"> </pre>

Alternatively, the reducer can be a pure function, like this

var reduced = options.reduce(function(result, option) {
  if (option.assigned) {
    return result.concat({
      name: option.name,
      newProperty: 'Foo'
    });
  }
  return result;
}, []);

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.

Though the reason mentioned by Kevin is correct, but I would definitely check below before moving to something else:

1. Check the cglibs in my classpath.
2. Check the hibernate versions in my classpath.

Chances are good that having multiple or conflicting version of any of the above could cause unexpected issues like the one in question.

It depends. You can throw a more general exception, or a more specific exception. For simpler methods, more general exceptions are enough. If the method is complex, then, throwing a more specific exception will be reliable.

the mime type might not be text/csv some systems can read/save them different. (for example sometimes IE sends .csv files as application/vnd.ms-excel) so you best bet would be to build an array of allowed values and test against that, then find all possible values to test against.

$mimes = array('application/vnd.ms-excel','text/plain','text/csv','text/tsv');
if(in_array($_FILES['file']['type'],$mimes)){
  // do something
} else {
  die("Sorry, mime type not allowed");
}

if you wished you could add a further check if mime is returned as text/plain you could run a preg_match to make sure it has enough commas in it to be a csv.

One of the major changes it seems is that with Android Studio the test application is integrated into the application project.

I'm not sure if this helps your specific problem, but I found a guide on making tests with a Gradle project. Android Gradle user Guide

The actual standards documents may not be the most useful. Most compilers do not fully implement the standards and may sometimes actually conflict. So the compiler documentation that you would already have will be more useful. Additionally, the documentation will contain platform-specific remarks and notes on any caveats.

override is a C++11 keyword which means that a method is an "override" from a method from a base class. Consider this example:

   class Foo
   {
   public:
        virtual void func1();
   }

   class Bar : public Foo
   {
   public:
        void func1() override;
   }

If B::func1() signature doesn't equal A::func1() signature a compilation error will be generated because B::func1() does not override A::func1(), it will define a new method called func1() instead.

Solution #1: Your statement

.Range(Cells(RangeStartRow, RangeStartColumn), Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

does not refer to a proper Range to act upon. Instead,

.Range(.Cells(RangeStartRow, RangeStartColumn), .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

does (and similarly in some other cases).

Solution #2: Activate Worksheets("Cable Cards") prior to using its cells.

Explanation: Cells(RangeStartRow, RangeStartColumn) (e.g.) gives you a Range, that would be ok, and that is why you often see Cells used in this way. But since it is not applied to a specific object, it applies to the ActiveSheet. Thus, your code attempts using .Range(rng1, rng2), where .Range is a method of one Worksheet object and rng1 and rng2 are in a different Worksheet.

There are two checks that you can do to make this quite evident:

1. Activate your Worksheets("Cable Cards") prior to executing your Sub and it will start working (now you have well-formed references to Ranges). For the code you posted, adding .Activate right after With... would indeed be a solution, although you might have a similar problem somewhere else in your code when referring to a Range in another Worksheet.

2. With a sheet other than Worksheets("Cable Cards") active, set a breakpoint at the line throwing the error, start your Sub, and when execution breaks, write at the immediate window

   Debug.Print Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   Debug.Print .Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   and see the different outcomes.

Conclusion: Using Cells or Range without a specified object (e.g., Worksheet, or Range) might be dangerous, especially when working with more than one Sheet, unless one is quite sure about what Sheet is active.

As I understand your question, You have one table with column as datatype decimal(18,9). And the column contains the data as follows:-

12.00
15.00
18.00
20.00

Now if you want to show record on UI without decimal value means like (12,15,18,20) then there are two options:-

1. Either cast this column as int in Select Clause
2. or may be you want to update this column value like (12,15,18,20).

To apply, First very simple just use the cast in select clause

select CAST(count AS INT) from tablename;

But if you want to update your column data with int value then you have to update you column datatype

and to do that

ALTER TABLE tablename ALTER COLUMN columnname decimal(9,0)

Then execute this

UPDATE tablename
   SET count = CAST(columnname AS INT)

this work for me and do not need change any config file

vim --cmd "set encoding=utf8" --cmd "set fileencoding=utf8" fileToOpen

The specific answer to this question is found in this one line below:

//pull the last two digits of the year_x000D_
//logs to console_x000D_
//creates a new date object (has the current date and time by default)_x000D_
//gets the full year from the date object (currently 2017)_x000D_
//converts the variable to a string_x000D_
//gets the substring backwards by 2 characters (last two characters)    _x000D_
console.log(new Date().getFullYear().toString().substr(-2));

No you can't; datetime will be stored in default format only while creating table and then you can change the display format in you select query the way you want using the Mysql Date Time Functions

The answer of ADTC works fine, but I've find another solution, so I post it here if someone wants something different.

I think ADTC's solution is better, but mine's also works.

Here is the other solution I found

select p.name
from   person p
where  instr(p.name,chr(8211)) > 0; --contains the character chr(8211) 
                                    --at least 1 time

Thank you.

Armin's answer is so useful, thank you. #2 is what's most important to know when trying to set up unload events that work in most browsers: you cannot alert() or confirm(), but returning a string will generate a confirm modal.

But I found that even with just returning a string, I had some cross-browser issues specific to Mootools (using version 1.4.5 in this instance). This Mootools-specific implementation worked great in Firefox, but did not result in a confirm popup in Chrome or Safari:

window.addEvent("beforeunload", function() {
    return "Are you sure you want to leave this page?";
});

So in order to get my onbeforeonload event to work across browsers, I had to use the JavaScript native call:

window.onbeforeunload = function() {
    return "Are you sure you want to leave this page?";
}

Not sure why this is the case, or if it's been fixed in later versions of Mootools.

You can also make full screen banner section without use of JavaScript, pure css based responsive full screen banner section , using height: 100vh; in banner main div, here have live example for this

#bannersection {
    position: relative;
    display: table;
    width: 100%;
    background: rgba(99,214,250,1);
    height: 100vh;
}

Java does not (yet) support closures. But there are other languages like Scala and Groovy which run in the JVM and do support closures.

The reason your tests are all being run is that you have the --filter flag after the file name. PHPUnit is not reading the options at all and so is running all the test cases.

From the help screen:

 Usage: phpunit [options] UnitTest [UnitTest.php]
        phpunit [options] <directory>

So move the --filter argument before the test file that you want as mentioned in @Alex and @Ferid Mövsümov answers. And you should only have the test that you want run.

For EXAMPLE

Your Path = /home/serverID_name/www/your_route_Dir/

THIS_is_the_DIR_I_Want

A Soultion that WORKS:

$url = dirname(\__FILE__);
$array = explode('\\\',$url);
$count = count($array);
echo $array[$count-1];

Array.from({length:5}, i => 1) // [1, 1, 1, 1, 1]

or create array with increasing value

Array.from({length:5}, (e, i)=>i) // [0, 1, 2, 3, 4]

Not very efficient, but if you must use a list, you can deference the iterator

*myList.begin()+N

After doing much R&D on this issue I got the Solution,

In my case I am using Service that will run every 2 second and with the runonUIThread, I was wondering the problem was there but not at all. The next issue that I found is that I am using large Image in may App and thats the problem.

I removed the Images and set new Images.

Conclusion :- Look into your code is there any raw file that you are using is of big size.

On SQL Server Management Studio

1. Right click Databases on left pane (Object Explorer)
2. Click Restore Database...
3. Choose Device, click ..., and add your .bak file
4. Click OK, then OK again

Done.

getline() is what you're looking for. You use strings in C++, and you don't need to know the size ahead of time.

Assuming std namespace:

 ifstream file1("myfile.txt");
 string stuff;

 while (getline(file1, stuff, '\n')) {
      cout << stuff << endl;
 }

 file1.close();

I like assylias' answer, however I would refactor it as follows:

Sub test()

Dim origNum As String
Dim creditOrDebit As String

origNum = "30062600006"
creditOrDebit = "D"

If creditOrDebit = "D" Then
  If origNum = "006260006" Then
    MsgBox "OK"
  ElseIf origNum = "30062600006" Then
    MsgBox "OK"
  End If
End If

End Sub

This might save you some CPU cycles since if creditOrDebit is <> "D" there is no point in checking the value of origNum.

Update:

I used the following procedure to test my theory that my procedure is faster:

Public Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub DoTests2()

  Dim startTime1 As Long
  Dim endTime1 As Long
  Dim startTime2 As Long
  Dim endTime2 As Long
  Dim i As Long
  Dim msg As String

  Const numberOfLoops As Long = 10000
  Const origNum As String = "006260006"
  Const creditOrDebit As String = "D"

  startTime1 = timeGetTime
  For i = 1 To numberOfLoops
    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        ' do something here
        Debug.Print "OK"
      ElseIf origNum = "30062600006" Then
        ' do something here
        Debug.Print "OK"
      End If
    End If
  Next i
  endTime1 = timeGetTime

  startTime2 = timeGetTime
  For i = 1 To numberOfLoops
    If (origNum = "006260006" Or origNum = "30062600006") And _
      creditOrDebit = "D" Then
      ' do something here
      Debug.Print "OK"
    End If
  Next i
  endTime2 = timeGetTime

  msg = "number of iterations: " & numberOfLoops & vbNewLine
  msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
       " ms" & vbNewLine
  msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
       " ms"

  MsgBox msg

End Sub

I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)

After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit is <>"D", my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.

And that is why I refactored it - to short-circuit the logic so that origNum doesn't need to be evaluated when creditOrDebit <> "D".

At this point, the rest depends on the OP's spreadsheet. If creditOrDebit is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit has a wide range of possible values, and D is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.

To programmatically load a view from a nib/xib in Swift 4:

// Load a view from a Nib given a placeholder view subclass
//      Placeholder is an instance of the view to load.  Placeholder is discarded.
//      If no name is provided, the Nib name is the same as the subclass type name
//
public func loadViewFromNib<T>(placeholder placeholderView: T, name givenNibName: String? = nil) -> T {

    let nib = loadNib(givenNibName, placeholder: placeholderView)
    return instantiateView(fromNib: nib, placeholder: placeholderView)
}

// Step 1: Returns a Nib
//
public func loadNib<T>(_ givenNibName: String? = nil, placeholder placeholderView: T) -> UINib {
    //1. Load and unarchive nib file
    let nibName = givenNibName ?? String(describing: type(of: placeholderView))

    let nib = UINib(nibName: nibName, bundle: Bundle.main)
    return nib
}

// Step 2: Instantiate a view given a nib
//
public func instantiateView<T>(fromNib nib: UINib, placeholder placeholderView: T) -> T {
    //1. Get top level objects
    let topLevelObjects = nib.instantiate(withOwner: placeholderView, options: nil)

    //2. Have at least one top level object
    guard let firstObject = topLevelObjects.first else {
        fatalError("\(#function): no top level objects in nib")
    }

    //3. Return instantiated view, placeholderView is not used
    let instantiatedView = firstObject as! T
    return instantiatedView
}

If additional table doesn't fit, you can write your own function for translation.

The plus of sql function over case is, that you can use it in various places, and keep translation logic in one place.

For swift 4.2, 5+

@IBOutlet weak var webView: UIWebView!

    override func viewDidLoad() {
       super.viewDidLoad()
           //Func Gose Here 
          let url = URL(string: link)
          let requestObj = URLRequest(url: url! as URL)
           webView.loadRequest(requestObj)

       }

I solved that problem.

I was implementing an OSI Layer (slider window, Level 2) for a network simulation in C++ (Eclipse Juno). I had frames (template <class T>) and its states (state pattern, forward declaration).

The solution is as follows:

In the *.cpp file, you must include the Header file that you forward, i.e.

ifndef STATE_H_
#define STATE_H_
#include <stdlib.h>
#include "Frame.h"

template <class T>
class LinkFrame;

using namespace std;

template <class T>
class State {

  protected:
    LinkFrame<int> *myFrame;

}

Its cpp:

#include "State.h"
#include "Frame.h"
#include  "LinkFrame.h"

template <class T>
bool State<T>::replace(Frame<T> *f){

And... another class.

Use:

class UtilSingleton: NSObject {

    var iVal: Int = 0

    class var shareInstance: UtilSingleton {
        get {
            struct Static {
                static var instance: UtilSingleton? = nil
                static var token: dispatch_once_t = 0
            }
            dispatch_once(&Static.token, {
                Static.instance = UtilSingleton()
            })
            return Static.instance!
        }
    }
}

How to use:

UtilSingleton.shareInstance.iVal++
println("singleton new iVal = \(UtilSingleton.shareInstance.iVal)")

Consider the case in which a service worker acts as an agnostic cache. Your only goal is serve the same resources that you would get from the network, but faster. Of course you can't ensure all the resources will be part of your origin (consider libraries served from CDNs, for instance). As the service worker has the potential of altering network responses, you need to guarantee you are not interested in the contents of the response, nor on its headers, nor even on the result. You're only interested on the response as a black box to possibly cache it and serve it faster.

This is what { mode: 'no-cors' } was made for.

I would use cat and tee based on the answers I saw at https://superuser.com/questions/32630/parallel-file-copy-from-single-source-to-multiple-targets instead of cp.

For example:

cat inputfile | tee outfile1 outfile2 > /dev/null

These are two ways of using a DLL file in Windows:

1. There is a stub library (.lib) with associated header files. When you link your executable with the lib-file it will automatically load the DLL file when starting the program.

2. Loading the DLL manually. This is typically what you want to do if you are developing a plugin system where there are many DLL files implementing a common interface. Check out the documentation for LoadLibrary and GetProcAddress for more information on this.

For Qt I would suspect there are headers and a static library available that you can include and link in your project.

$(document).on('click', 'selector', handler);

Where click is an event name, and handler is an event handler, like reference to a function or anonymous function function() {}

PS: if you know the particular node you're adding dynamic elements to - you could specify it instead of document.

Primitives are passed by value. But in case you only need to read the value of a primitve (and value is not known at the time when function is called) you can pass function which retrieves the value at the moment you need it.

function test(value) {
  console.log('retrieve value');
  console.log(value());
}

// call the function like this
var value = 1;
test(() => value);

another great and easy way is to have a blind modal in your layout and call it if neccessary.

JS

  var remote_modal = function(url) {
    // reset modal body with a spinner or empty content
    spinner = "<div class='text-center'><i class='fa fa-spinner fa-spin fa-5x fa-fw'></i></div>"

    $("#remote-modal .modal-body").html(spinner)
    $("#remote-modal .modal-body").load(url);
    $("#remote-modal").modal("show");
  }

and your HTML

 <div class='modal fade' id='remote-modal'>
    <div class='modal-dialog modal-lg'>
      <div class='modal-content'>
        <div class='modal-body'></div>
        <div class='modal-footer'>
          <button class='btn btn-default'>Close</button>
        </div>
      </div>
    </div>
  </div>
</body>

now you can simply call remote_modal('/my/url.html') and the content gets displayed inside of the modal

Get your object's constructor function and then inspect its name property.

myObj.constructor.name

Returns "myClass".

require 'date'

date = DateTime.parse("2011-05-19 10:30:14")
formatted_date = date.strftime('%a %b %d %H:%M:%S %Z %Y')

See strftime() for more information about formatting dates.

Source article: Passing a list as an argument to a vararg method

Use the toArray(T[] arr) method.

.getMap(locations.toArray(new WorldLocation[locations.size()]))

(toArray(new WorldLocation[0]) also works, but you would allocate a zero-length array for no reason.)

Here's a complete example:

public static void method(String... strs) {
    for (String s : strs)
        System.out.println(s);
}

...
    List<String> strs = new ArrayList<String>();
    strs.add("hello");
    strs.add("world");
    
    method(strs.toArray(new String[strs.size()]));
    //     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...

This might be your problem:

height: .05em;

Chrome is a bit funky with decimals, so try a fixed-pixel height:

height: 2px;

I know this is a very old thread but just incase someone like myself needs this solution but in VB.NET here's what I used base on the answers above.

Private Function ValidateUniquePayroll(PropertyToCheck As String) As Boolean
    // Return true if Username is Unique
    Dim rtnValue = False
    Dim context = New CPMModel.CPMEntities
    If (context.Employees.Any()) Then ' Check if there are "any" records in the Employee table
        Dim employee = From c In context.Employees Select c.PayrollNumber ' Select just the PayrollNumber column to work with
        For Each item As Object In employee ' Loop through each employee in the Employees entity
            If (item = PropertyToCheck) Then ' Check if PayrollNumber in current row matches PropertyToCheck
                // Found a match, throw exception and return False
                rtnValue = False
                Exit For
            Else
                // No matches, return True (Unique)
                rtnValue = True
            End If
        Next
    Else
        // The is currently no employees in the person entity so return True (Unqiue)
        rtnValue = True
    End If
    Return rtnValue
End Function

If you have more then 1 dimension array

with open("file.txt", 'w') as output:
    for row in values:
        output.write(str(row) + '\n')

Code to write without '[' and ']'

with open("file.txt", 'w') as file:
        for row in values:
            s = " ".join(map(str, row))
            file.write(s+'\n')

If the space on that page is not disabled then put your button inside a div.

<div id="a1">
<button>Click here</button>
</div>

Using Jquery:

<script language="javascript">
$("#a1").hide();
</script>

Using JS:

<script language="javascript">
document.getElementById("a1").style.visibility = "hidden";
document.getElementById("a1").style.display = "none";
</script>

This solution uses one function to split milliseconds into a parts object, and another function to format the parts object.

I created 2 format functions, one as you requested, and another that prints a friendly string and considering singular/plural, and includes an option to show milliseconds.

function parseDuration(duration) {_x000D_

You need to add /// Comment for the member for which warning is displayed.

see below code

public EventLogger()
{
    LogFile = string.Format("{0}{1}", LogFilePath, FileName);
}

It displays warning Missing XML comment for publicly visible type or member '.EventLogger()'

I added comment for the member and warning gone.

///<Summary>
/// To write a log <Anycomment as per your code>
///</Summary>
public EventLogger()
{
    LogFile = string.Format("{0}{1}", LogFilePath, FileName);
}

I use this:

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.InputStream;

public class IconImageUtilities
{
    public static void setIconImage(Window window)
    {
        try
        {
            InputStream imageInputStream = window.getClass().getResourceAsStream("/Icon.png");
            BufferedImage bufferedImage = ImageIO.read(imageInputStream);
            window.setIconImage(bufferedImage);
        } catch (IOException exception)
        {
            exception.printStackTrace();
        }
    }
}

Just place your image called Icon.png in the resources folder and call the above method with itself as parameter inside a class extending a class from the Window family such as JFrame or JDialog:

IconImageUtilities.setIconImage(this);

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

If you're using Visual C++, you can non-portably do this using hints to the linker...

// In foo.h...

class Foo
{
public:
   static const char *Bar;
};

// Still in foo.h; doesn't need to be in a .cpp file...

__declspec(selectany)
const char *Foo::Bar = "Blah";

__declspec(selectany) means that even though Foo::Bar will get declared in multiple object files, the linker will only pick up one.

Keep in mind this will only work with the Microsoft toolchain. Don't expect this to be portable.

If you want to insert object, use this:

    currentLogs = [
 { socket_id: 'Server', message: 'Socketio online', data: 'Port  3333', logged: '2014-05-14 14:41:11' },
 { socket_id: 'Server', message: 'Waiting for Pi to connect...', data: 'Port: 8082', logged: '2014-05-14 14:41:11' }
];

console.warn(currentLogs.map(logs=>[ logs.socket_id , logs.message , logs.data , logs.logged ]));

The output will be:

[
  [ 'Server', 'Socketio online', 'Port  3333', '2014-05-14 14:41:11' ],
  [
    'Server',
    'Waiting for Pi to connect...',
    'Port: 8082',
    '2014-05-14 14:41:11'
  ]
]

Also, please check the documentation to know more about the map function.

From the documentation:

list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a),x) is equivalent to a.append(x)

http://docs.python.org/2/tutorial/datastructures.html#more-on-lists

Use this:

this.CenterToScreen();  // This will take care of the current form

For deleting all data:

HTML FILE

  class="btn btn-primary" href="{% url 'delete_product'%}">Delete

Put the above code in an anchor tag. (the a tag!)

url.py

path('delete_product', views.delete_product, name='delete_product')]

views.py

def delete_product(request):
    if request.method == "GET":
        dest = Racket.objects.all()
        dest.delete()
        return render(request, "admin_page.html")

Also make sure the div is currently appended to the DOM and visible.

1. Typically in a dotfile (like .myprogramrc) in the user's home directory.
2. It is of course up to the programmer but normally command line arguments override everything else. If environment variables are used it is usually as an alternative to the command line arguments or to specify where the configuration is located.

Update on 11 December 2015

Username + password is no longer a recommended solution. This is due to

I tried this and Gmail sent the email used as username in this code an email saying that We recently blocked a sign-in attempt to your Google Account, and directed me to this support page: support.google.com/accounts/answer/6010255 so it looks for it to work, the email account being used to send needs to reduce their own security

Google had released Gmail API - https://developers.google.com/gmail/api/?hl=en. We should use oAuth2 method, instead of username + password.

Here's the code snippet to work with Gmail API.

GoogleMail.java

import com.google.api.client.util.Base64;
import com.google.api.services.gmail.Gmail;
import com.google.api.services.gmail.model.Message;
import java.io.ByteArrayOutputStream;

import java.util.Properties;

import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

/**

 */
public class GoogleMail {
    private GoogleMail() {
    }

    private static MimeMessage createEmail(String to, String cc, String from, String subject, String bodyText) throws MessagingException {
        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);

        MimeMessage email = new MimeMessage(session);
        InternetAddress tAddress = new InternetAddress(to);
        InternetAddress cAddress = cc.isEmpty() ? null : new InternetAddress(cc);
        InternetAddress fAddress = new InternetAddress(from);

        email.setFrom(fAddress);
        if (cAddress != null) {
            email.addRecipient(javax.mail.Message.RecipientType.CC, cAddress);
        }
        email.addRecipient(javax.mail.Message.RecipientType.TO, tAddress);
        email.setSubject(subject);
        email.setText(bodyText);
        return email;
    }

    private static Message createMessageWithEmail(MimeMessage email) throws MessagingException, IOException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        email.writeTo(baos);
        String encodedEmail = Base64.encodeBase64URLSafeString(baos.toByteArray());
        Message message = new Message();
        message.setRaw(encodedEmail);
        return message;
    }

    public static void Send(Gmail service, String recipientEmail, String ccEmail, String fromEmail, String title, String message) throws IOException, MessagingException {
        Message m = createMessageWithEmail(createEmail(recipientEmail, ccEmail, fromEmail, title, message));
        service.users().messages().send("me", m).execute();
    }
}

Without building temporary lists:

>>> import itertools
>>> s = 'abcdefgh'
>>> si = iter(s)
>>> [''.join(each) for each in itertools.izip(si, si)]
['ab', 'cd', 'ef', 'gh']

or:

>>> import itertools
>>> s = 'abcdefgh'
>>> si = iter(s)
>>> map(''.join, itertools.izip(si, si))
['ab', 'cd', 'ef', 'gh']

Oracle views like ALL_TABLES and ALL_CONSTRAINTS have an owner column, which you can use to restrict your query. There are also variants of these tables beginning with USER instead of ALL, which only list objects which can be accessed by the current user.

One of these views should help to solve your problem. They always worked fine for me for similar problems.

What you want is called an associative array. In python these are called dictionaries.

Dictionaries are sometimes found in other languages as “associative memories” or “associative arrays”. Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys.

myDict = {}
myDict["john"] = "johns value"
myDict["jeff"] = "jeffs value"

Alternative way to create the above dict:

myDict = {"john": "johns value", "jeff": "jeffs value"}

Accessing values:

print(myDict["jeff"]) # => "jeffs value"

Getting the keys (in Python v2):

print(myDict.keys()) # => ["john", "jeff"]

In Python 3, you'll get a dict_keys, which is a view and a bit more efficient (see views docs and PEP 3106 for details).

print(myDict.keys()) # => dict_keys(['john', 'jeff']) 

If you want to learn about python dictionary internals, I recommend this ~25 min video presentation: https://www.youtube.com/watch?v=C4Kc8xzcA68. It's called the "The Mighty Dictionary".

You need to use delegates and protocols. Here is a site with an example http://iosdevelopertips.com/objective-c/the-basics-of-protocols-and-delegates.html

And here comes my solution :) It is various of earlier solutions, but developed on my own - maybe somebody enjoy it more then other propositions.

TENS = {30: 'thirty', 40: 'forty', 50: 'fifty', 60: 'sixty', 70: 'seventy', 80: 'eighty', 90: 'ninety'}
ZERO_TO_TWENTY = (
    'zero', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten',
    'eleven', 'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen', 'twenty'
)

def number_to_english(n):
    if any(not x.isdigit() for x in str(n)):
        return ''

    if n <= 20:
        return ZERO_TO_TWENTY[n]
    elif n < 100 and n % 10 == 0:
        return TENS[n]
    elif n < 100:
        return number_to_english(n - (n % 10)) + ' ' + number_to_english(n % 10)
    elif n < 1000 and n % 100 == 0:
        return number_to_english(n / 100) + ' hundred'
    elif n < 1000:
        return number_to_english(n / 100) + ' hundred ' + number_to_english(n % 100)
    elif n < 1000000:
        return number_to_english(n / 1000) + ' thousand ' + number_to_english(n % 1000)

    return ''

It is recoursive solution and can be easily expand for bigger numbers

Python does not have a defined entry point like Java, C, C++, etc. Rather it simply executes a source file line-by-line. The if statement allows you to create a main function which will be executed if your file is loaded as the "Main" module rather than as a library in another module.

To be clear, this means that the Python interpreter starts at the first line of a file and executes it. Executing lines like class Foobar: and def foobar() creates either a class or a function and stores them in memory for later use.

If you encounter an issue in which pylab.show() freezes the IPython window (this may be Mac OS X specific; not sure), you can cmd-c in the IPython window, switch to the plot window, and it will break out.

Apparently, future calls to pylab.show() will not freeze the IPython window, only the first call. Unfortunately, I've found that the behavior of the plot window / interactions with show() changes every time I reinstall matplotlib, so this solution may not always hold.

How to get the height of the navigation bar and status bar. This code works for me on some Huawei devices and Samsung devices. Egis's solution above is good, however, it is still incorrect on some devices. So, I improved it.

This is code to get the height of status bar

private fun getStatusBarHeight(resources: Resources): Int {
        var result = 0
        val resourceId = resources.getIdentifier("status_bar_height", "dimen", "android")
        if (resourceId > 0) {
            result = resources.getDimensionPixelSize(resourceId)
        }
        return result
    }

This method always returns the height of navigation bar even when the navigation bar is hidden.

private fun getNavigationBarHeight(resources: Resources): Int {
    val resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android")
    return if (resourceId > 0) {
        resources.getDimensionPixelSize(resourceId)
    } else 0
}

NOTE: on Samsung A70, this method returns the height of the status bar + height of the navigation bar. On other devices (Huawei), it only returns the height of the Navigation bar and returns 0 when the navigation bar is hidden.

private fun getNavigationBarHeight(): Int {
        val display = activity?.windowManager?.defaultDisplay
        return if (display == null) {
            0
        } else {
            val realMetrics = DisplayMetrics()
            display.getRealMetrics(realMetrics)
            val metrics = DisplayMetrics()
            display.getMetrics(metrics)
            realMetrics.heightPixels - metrics.heightPixels
        }
    }

This is code to get height of navigation bar and status bar

val metrics = DisplayMetrics()
        activity?.windowManager?.defaultDisplay?.getRealMetrics(metrics)

        //resources is got from activity

        //NOTE: on SamSung A70, this height = height of status bar + height of Navigation bar
        //On other devices (Huawei), this height = height of Navigation bar
        val navigationBarHeightOrNavigationBarPlusStatusBarHeight = getNavigationBarHeight()

        val statusBarHeight = getStatusBarHeight(resources)
        //The method will always return the height of navigation bar even when the navigation bar was hidden.
        val realNavigationBarHeight = getNavigationBarHeight(resources)

        val realHeightOfStatusBarAndNavigationBar =
                if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == 0 || navigationBarHeightOrNavigationBarPlusStatusBarHeight < statusBarHeight) {
                    //Huawei: navigation bar is hidden
                    statusBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == realNavigationBarHeight) {
                    //Huawei: navigation bar is visible
                    statusBarHeight + realNavigationBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight < realNavigationBarHeight) {
                    //SamSung A70: navigation bar is still visible but it only displays as a under line
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight = navigationBarHeight'(under line) + statusBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                } else {
                    //SamSung A70: navigation bar is visible
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight == statusBarHeight + realNavigationBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                }

Just use like this

 $("#sample_id").css("width", "");
 $("#sample_id").css("height", "");

The message above means that you're running so many programs on your PC that there is no memory left to run one more. This isn't a Java problem and no Java option is going to change this.

Use the Task Manager of Windows to see how much of your 4GB RAM is actually free. My guess is that somewhere, you have a program that eats all the memory. Find it and kill it.

EDIT You need to understand that there are two types of "out of memory" errors.

The first one is the OutOfMemoryException which you get when Java code is running and the Java heap is not large enough. This means Java code asks the Java runtime for memory. You can fix those with -Xmx...

The other error is when the Java runtime runs out of memory. This isn't related to the Java heap at all. This is an error when Java asks the OS for more memory and the OS says: "Sorry, I don't have any."

To fix the latter, close applications or reboot (to clean up memory fragmentation).

I wasn't completely happy by the --allow-file-access-from-files solution, because I'm using Chrome as my primary browser, and wasn't really happy with this breach I was opening.

Now I'm using Canary ( the chrome beta version ) for my development with the flag on. And the mere Chrome version for my real blogging : the two browser don't share the flag !

I'm not certain what's wrong with your code specifically, but I use this function I found online (URL in the comments) for checking if a file exists:

Private Function File_Exists(ByVal sPathName As String, Optional Directory As Boolean) As Boolean
    'Code from internet: http://vbadud.blogspot.com/2007/04/vba-function-to-check-file-existence.html
    'Returns True if the passed sPathName exist
    'Otherwise returns False
    On Error Resume Next
    If sPathName <> "" Then

        If IsMissing(Directory) Or Directory = False Then

            File_Exists = (Dir$(sPathName) <> "")
        Else

            File_Exists = (Dir$(sPathName, vbDirectory) <> "")
        End If

    End If
End Function

You can also define the pointcut as

public pointcut publicMethodInsideAClassMarkedWithAtMonitor() : execution(public * (@Monitor *).*(..));

You can indeed not define the filter execution order using @WebFilter annotation. However, to minimize the web.xml usage, it's sufficient to annotate all filters with just a filterName so that you don't need the <filter> definition, but just a <filter-mapping> definition in the desired order.

For example,

@WebFilter(filterName="filter1")
public class Filter1 implements Filter {}

@WebFilter(filterName="filter2")
public class Filter2 implements Filter {}

with in web.xml just this:

<filter-mapping>
    <filter-name>filter1</filter-name>
    <url-pattern>/url1/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>filter2</filter-name>
    <url-pattern>/url2/*</url-pattern>
</filter-mapping>

If you'd like to keep the URL pattern in @WebFilter, then you can just do like so,

@WebFilter(filterName="filter1", urlPatterns="/url1/*")
public class Filter1 implements Filter {}

@WebFilter(filterName="filter2", urlPatterns="/url2/*")
public class Filter2 implements Filter {}

but you should still keep the <url-pattern> in web.xml, because it's required as per XSD, although it can be empty:

<filter-mapping>
    <filter-name>filter1</filter-name>
    <url-pattern />
</filter-mapping>
<filter-mapping>
    <filter-name>filter2</filter-name>
    <url-pattern />
</filter-mapping>

Regardless of the approach, this all will fail in Tomcat until version 7.0.28 because it chokes on presence of <filter-mapping> without <filter>. See also Using Tomcat, @WebFilter doesn't work with <filter-mapping> inside web.xml

You can't do that. It is invalid HTML. You can't put a <a> in between a <tbody> and a <tr>. Try this instead:

<tr onclick="window.location='#';">
        ...
     </tr>

add style for pointer view

[data-href] { cursor: pointer; }

When you work up to it, you'd want to use JavaScript to assign the click handler outside of the HTML.

I use this: https://github.com/Homebrew/homebrew-php

The command is:

$ xcode-select --install

$ brew tap homebrew/dupes
$ brew tap homebrew/versions
$ brew tap homebrew/homebrew-php

$ brew options php56
$ brew install php56

Then config in your .bash_profile or .bashrc

# Homebrew PHP CLI
export PATH="$(brew --prefix homebrew/php/php56)/bin:$PATH"

In the spirit of being complete, the answers that instruct you to use Guid.NewGuid() are correct.

In addressing your subsequent edit, you'll need to post the code for your RequestObject class. I'm suspecting that your guid property is not marked as a DataMember, and thus is not being serialized over the wire. Since default(Guid) is the same as new Guid() (i.e. all 0's), this would explain the behavior you're seeing.

Here it is in one line:

jar cvfe myjar.jar package.MainClass *.class

where MainClass is the class with your main method, and package is MainClass's package.

Note you have to compile your .java files to .class files before doing this.

c  create new archive
v  generate verbose output on standard output
f  specify archive file name
e  specify application entry point for stand-alone application bundled into an executable jar file

_{This answer inspired by Powerslave's comment on another answer.}

As others said, the main problem with the OP code is that the operator + does not concatenate const char *; it works with std::string, though.

Here's another solution that uses C++11 lambdas and for_each and allows to provide a separator to separate the strings:

#include <vector>
#include <algorithm>
#include <iterator>
#include <sstream>

string join(const string& separator,
            const vector<string>& strings)
{
    if (strings.empty())
        return "";

    if (strings.size() == 1)
        return strings[0];

    stringstream ss;
    ss << strings[0];

    auto aggregate = [&ss, &separator](const string& s) { ss << separator << s; };
    for_each(begin(strings) + 1, end(strings), aggregate);

    return ss.str();
}

Usage:

std::vector<std::string> strings { "a", "b", "c" };
std::string joinedStrings = join(", ", strings);

It seems to scale well (linearly), at least after a quick test on my computer; here's a quick test I've written:

#include <vector>
#include <algorithm>
#include <iostream>
#include <iterator>
#include <sstream>
#include <chrono>

using namespace std;

string join(const string& separator,
            const vector<string>& strings)
{
    if (strings.empty())
        return "";

    if (strings.size() == 1)
        return strings[0];

    stringstream ss;
    ss << strings[0];

    auto aggregate = [&ss, &separator](const string& s) { ss << separator << s; };
    for_each(begin(strings) + 1, end(strings), aggregate);

    return ss.str();
}

int main()
{
    const int reps = 1000;
    const string sep = ", ";
    auto generator = [](){return "abcde";};

    vector<string> strings10(10);
    generate(begin(strings10), end(strings10), generator);

    vector<string> strings100(100);
    generate(begin(strings100), end(strings100), generator);

    vector<string> strings1000(1000);
    generate(begin(strings1000), end(strings1000), generator);

    vector<string> strings10000(10000);
    generate(begin(strings10000), end(strings10000), generator);

    auto t1 = chrono::system_clock::now();
    for(int i = 0; i<reps; ++i)
    {
        join(sep, strings10);
    }

    auto t2 = chrono::system_clock::now();
    for(int i = 0; i<reps; ++i)
    {
        join(sep, strings100);
    }

    auto t3 = chrono::system_clock::now();
    for(int i = 0; i<reps; ++i)
    {
        join(sep, strings1000);
    }

    auto t4 = chrono::system_clock::now();
    for(int i = 0; i<reps; ++i)
    {
        join(sep, strings10000);
    }

    auto t5 = chrono::system_clock::now();

    auto d1 = chrono::duration_cast<chrono::milliseconds>(t2 - t1);
    auto d2 = chrono::duration_cast<chrono::milliseconds>(t3 - t2);
    auto d3 = chrono::duration_cast<chrono::milliseconds>(t4 - t3);
    auto d4 = chrono::duration_cast<chrono::milliseconds>(t5 - t4);

    cout << "join(10)   : " << d1.count() << endl;
    cout << "join(100)  : " << d2.count() << endl;
    cout << "join(1000) : " << d3.count() << endl;
    cout << "join(10000): " << d4.count() << endl;
}

Results (milliseconds):

join(10)   : 2
join(100)  : 10
join(1000) : 91
join(10000): 898

No need to use grep. ps in Android can filter by COMM value (last 15 characters of the package name in case of java app)

Let's say we want to check if com.android.phone is running:

adb shell ps m.android.phone
USER     PID   PPID  VSIZE  RSS     WCHAN    PC         NAME
radio     1389  277   515960 33964 ffffffff 4024c270 S com.android.phone

Filtering by COMM value option has been removed from ps in Android 7.0. To check for a running process by name in Android 7.0 you can use pidof command:

adb shell pidof com.android.phone

It returns the PID if such process was found or an empty string otherwise.

You can also enable live-logging by setting the following in pytest.ini or tox.ini in your project root.

[pytest]
log_cli = True

Or specify it directly on cli

pytest -o log_cli=True

I have added screenshots of a working environment, because it cost me several hours of R&D.

1. First, add a key to your launch.json file.

   See the below screenshot, I have added Development as my environment.

   

2. Then, in your project, create a new appsettings.{environment}.json file that includes the name of the environment.

   In the following screenshot, look for two different files with the names:

   • appsettings.Development.Json
   • appSetting.json

   
   

3. And finally, configure it to your StartUp class like this:

   public Startup(IHostingEnvironment env)
   {
       var builder = new ConfigurationBuilder()
           .SetBasePath(env.ContentRootPath)
           .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
           .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
           .AddEnvironmentVariables();
   
       Configuration = builder.Build();
   }
   

4. And at last, you can run it from the command line like this:

   dotnet run --environment "Development"
   

   where "Development" is the name of my environment.

Include your IP address in your host file (C:\Windows\System32\drivers\etc\host) for the respective server:

Sample Entry:

10.100.101.102 server1.us.vijay.com Vijay's Server

Think of a GrantedAuthority as being a "permission" or a "right". Those "permissions" are (normally) expressed as strings (with the getAuthority() method). Those strings let you identify the permissions and let your voters decide if they grant access to something.

You can grant different GrantedAuthoritys (permissions) to users by putting them into the security context. You normally do that by implementing your own UserDetailsService that returns a UserDetails implementation that returns the needed GrantedAuthorities.

Roles (as they are used in many examples) are just "permissions" with a naming convention that says that a role is a GrantedAuthority that starts with the prefix ROLE_. There's nothing more. A role is just a GrantedAuthority - a "permission" - a "right". You see a lot of places in spring security where the role with its ROLE_ prefix is handled specially as e.g. in the RoleVoter, where the ROLE_ prefix is used as a default. This allows you to provide the role names withtout the ROLE_ prefix. Prior to Spring security 4, this special handling of "roles" has not been followed very consistently and authorities and roles were often treated the same (as you e.g. can see in the implementation of the hasAuthority() method in SecurityExpressionRoot - which simply calls hasRole()). With Spring Security 4, the treatment of roles is more consistent and code that deals with "roles" (like the RoleVoter, the hasRole expression etc.) always adds the ROLE_ prefix for you. So hasAuthority('ROLE_ADMIN') means the the same as hasRole('ADMIN') because the ROLE_ prefix gets added automatically. See the spring security 3 to 4 migration guide for futher information.

But still: a role is just an authority with a special ROLE_ prefix. So in Spring security 3 @PreAuthorize("hasRole('ROLE_XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')") and in Spring security 4 @PreAuthorize("hasRole('XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')").

Regarding your use case:

Users have roles and roles can perform certain operations.

You could end up in GrantedAuthorities for the roles a user belongs to and the operations a role can perform. The GrantedAuthorities for the roles have the prefix ROLE_ and the operations have the prefix OP_. An example for operation authorities could be OP_DELETE_ACCOUNT, OP_CREATE_USER, OP_RUN_BATCH_JOBetc. Roles can be ROLE_ADMIN, ROLE_USER, ROLE_OWNER etc.

You could end up having your entities implement GrantedAuthority like in this (pseudo-code) example:

@Entity
class Role implements GrantedAuthority {
    @Id
    private String id;

    @ManyToMany
    private final List<Operation> allowedOperations = new ArrayList<>();

    @Override
    public String getAuthority() {
        return id;
    }

    public Collection<GrantedAuthority> getAllowedOperations() {
        return allowedOperations;
    }
}

@Entity
class User {
    @Id
    private String id;

    @ManyToMany
    private final List<Role> roles = new ArrayList<>();

    public Collection<Role> getRoles() {
        return roles;
    }
}

@Entity
class Operation implements GrantedAuthority {
    @Id
    private String id;

    @Override
    public String getAuthority() {
        return id;
    }
}

The ids of the roles and operations you create in your database would be the GrantedAuthority representation, e.g. ROLE_ADMIN, OP_DELETE_ACCOUNT etc. When a user is authenticated, make sure that all GrantedAuthorities of all its roles and the corresponding operations are returned from the UserDetails.getAuthorities() method.

Example: The admin role with id ROLE_ADMIN has the operations OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB assigned to it. The user role with id ROLE_USER has the operation OP_READ_ACCOUNT.

If an admin logs in the resulting security context will have the GrantedAuthorities: ROLE_ADMIN, OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB

If a user logs it, it will have: ROLE_USER, OP_READ_ACCOUNT

The UserDetailsService would take care to collect all roles and all operations of those roles and make them available by the method getAuthorities() in the returned UserDetails instance.

I got the same problem and it is not the solution that you told. So I changed the "from datetime import datetime" to "import datetime". After that with the help of "datetime.datetime" I can get the whole modules correctly. I guess this is the correct answer to that question.

A pure CSS solution (#content { min-height: 100%; }) will work in a lot of cases, but not in all of them - especially IE6 and IE7.

Unfortunately, you will need to resort to a JavaScript solution in order to get the desired behavior. This can be done by calculating the desired height for your content <div> and setting it as a CSS property in a function:

function resizeContent() {
  var contentDiv = document.getElementById('content');
  var headerDiv = document.getElementById('header');
  // This may need to be done differently on IE than FF, but you get the idea.
  var viewPortHeight = window.innerHeight - headerDiv.clientHeight;
  contentDiv.style.height = 
    Math.max(viewportHeight, contentDiv.clientHeight) + 'px';
}

You can then set this function as a handler for onLoad and onResize events:

<body onload="resizeContent()" onresize="resizeContent()">
  . . .
</body>

jQuery 3.3.1

if (typeof $("input[name='yourRadioName']:checked").val() === "undefined") {
    alert('is not selected');
}else{
    alert('is selected');
}

The video tag can play audio as well. Given the audio tag doesn't seem to be behaving as it should be, you can just use the video tag for audio:

<video autoplay muted id="audio1" src="your.mp3" type="audio/mp3">
    Your browser does not support the <code>video</code> element.
</video>
<script>
    unmuteButton.addEventListener('click', function() 
        { 
            if ( unmuteButton.innerHTML == "unmute" )
            {
                unmuteButton.innerHTML = "mute";
                audio1.muted = false; 
            } else {
                unmuteButton.innerHTML = "unmute";
                audio1.muted = true; 
            }
        });
</script>

There is a difference, and you should prefer class to typename.

But why?

typename is illegal for template template arguments, so to be consistent, you should use class:

template<template<class> typename MyTemplate, class Bar> class Foo { };    //  :(
template<template<class>    class MyTemplate, class Bar> class Foo { };    //  :)

This:

var txt=new RegExp(pattern,attributes);

is equivalent to this:

var txt=/pattern/attributes;

See http://www.w3schools.com/jsref/jsref_obj_regexp.asp.

A bit late but this should work.

my_dict = {}
my_dict[key] = my_dict[key] + 1 if key in my_dict else 1

I just made a simple test to see how instanceOf performance is comparing to a simple s.equals() call to a string object with only one letter.

in a 10.000.000 loop the instanceOf gave me 63-96ms, and the string equals gave me 106-230ms

I used java jvm 6.

So in my simple test is faster to do a instanceOf instead of a one character string comparison.

using Integer's .equals() instead of string's gave me the same result, only when I used the == i was faster than instanceOf by 20ms (in a 10.000.000 loop)

For downloading pdf from server , add below code in your service class. Hope this is helpful for you.

File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), fileName + ".pdf");
    intent = new Intent(Intent.ACTION_VIEW);
    //Log.e("pathOpen", file.getPath());

    Uri contentUri;
    contentUri = Uri.fromFile(file);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);

    if (Build.VERSION.SDK_INT >= 24) {

        Uri apkURI = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", file);
        intent.setDataAndType(apkURI, "application/pdf");
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

    } else {

        intent.setDataAndType(contentUri, "application/pdf");
    }

And yes , don't forget to add permissions and provider in your manifest.

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

<application

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>

</application>

Since my previous answer I came up with another solution that is different and perhaps better. This code allows processes to be run more than 60 times a minute with microsecond precision. You need the usleep program to make this work. Should be good to up to 50 times a second.

if [ $# -eq 0 ]
then
   echo
   echo "cron-ms by Marc Perkel"
   echo
   echo "This program is used to run all programs in a directory in parallel every X times per minute."
   echo "Think of this program as cron with microseconds resolution."
   echo
   echo "Usage: cron-ms start"
   echo
   echo "The scheduling is done by creating directories with the number of"
   echo "executions per minute as part of the directory name."
   echo
   echo "Examples:"
   echo "  /etc/cron-ms/7      # Executes everything in that directory  7 times a minute"
   echo "  /etc/cron-ms/30     # Executes everything in that directory 30 times a minute"
   echo "  /etc/cron-ms/600    # Executes everything in that directory 10 times a second"
   echo "  /etc/cron-ms/2400   # Executes everything in that directory 40 times a second"
   echo
   exit
fi

# If "start" is passed as a parameter then run all the loops in parallel
# The number of the directory is the number of executions per minute
# Since cron isn't accurate we need to start at top of next minute

then

   done
   exit

# Loops per minute and the next interval are passed on the command line with each loop

loops=$1
next_interval=$2

# Sleeps until a specific part of a minute with microsecond resolution. 60000000 is full minute

usleep $(( $next_interval - 10#$(date +%S%N) / 1000 ))

# Run all the programs in the directory in parallel

for program in $basedir/$loops/* ; do
   if [ -x $program ] 
   then
      $program &> /dev/null &
   fi
done

# Calculate next_interval

next_interval=$(($next_interval % 60000000 + (60000000 / $loops) ))

# If minute is not up - call self recursively

It depends on the database you are using. MySQL for example supports the (non-standard) group_concat function. So you could write:

SELECT GROUP_CONCAT(ModuleValue) FROM Table_X WHERE ModuleID=@ModuleID

Group-concat is not available at all database servers though.

You can use

$(window).on('load', function() {
    // your code here
});

Which will wait until the page is loaded. $(document).ready() waits until the DOM is loaded.

In plain JS:

window.addEventListener('load', function() {
    // your code here
})

In MSBuild or Teamcity use command line

MSBuild yourproject.sln /property:Configuration=Release /property:Platform=x64

or use shorter form:

MSBuild yourproject.sln /p:Configuration=Release /p:Platform=x64

However you need to set up platform in your project anyway, see the answer by Julien Hoarau.

They are project files, that hold the module information and meta data.

Just add *.iml to .gitignore.

In Android Studio: Press CTRL + F9 to rebuild your project. The missing *.iml files will be generated.

Here are two examples of how to generate graphs in separate windows (frames), and, an example of how to generate graphs and save them into separate graphics files.

Okay, first the on-screen example. Notice that we use a separate instance of plt.figure(), for each graph, with plt.plot(). At the end, we have to call plt.show() to put it all on the screen.

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace( 0,10 )

for n in range(3):
    y = np.sin( x+n )
    plt.figure()
    plt.plot( x, y )

plt.show()

Another way to do this, is to use plt.show(block=False) inside the loop:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace( 0,10 )

for n in range(3):
    y = np.sin( x+n )
    plt.figure()
    plt.plot( x, y )
    plt.show( block=False )

Now, let's generate the graphs and instead, write them each to a file. Here we replace plt.show(), with plt.savefig( filename ). The difference from the previous example is that we don't have to account for ''blocking'' at each graph. Note also, that we number the file names. Here we use %03d so that we can conveniently have them in number order afterwards.

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace( 0,10 )

for n in range(3):
    y = np.sin( x+n )
    plt.figure()
    plt.plot( x, y )
    plt.savefig('myfilename%03d.png'%(n))

I was having the same trouble, the problem for me was that adb was not in the right environment path, the error is telling you metro port, while you're in the adb, ports are killed and restarted.

Add Enviroment Variable (ADB)

1. Open environment variables
2. Select from the second frame PATH variable and click edit option below
3. Click on add option
4. Submit the sdk platform tools path C:\Users\ My User \AppData\Local\Android\Sdk\platform-tools

Note: Or depending where is located adb.exe in your machine

5. Save changes

Run android build again

$ react-native run-android

Or

$ react-native start

$ react-native run-android

In bootstrap 3, it is recommended that you size inputs by wrapping them in col-**-# div tags. It seems that most things have 100% width, especially .form-control elements.

One way is to run the program in a subshell, and communicate with the subshell through a named pipe with the read command. This way you can check the exit status of the process being run and communicate this back through the pipe.

Here's an example of timing out the yes command after 3 seconds. It gets the PID of the process using pgrep (possibly only works on Linux). There is also some problem with using a pipe in that a process opening a pipe for read will hang until it is also opened for write, and vice versa. So to prevent the read command hanging, I've "wedged" open the pipe for read with a background subshell. (Another way to prevent a freeze to open the pipe read-write, i.e. read -t 5 <>finished.pipe - however, that also may not work except with Linux.)

rm -f finished.pipe
mkfifo finished.pipe

{ yes >/dev/null; echo finished >finished.pipe ; } &
SUBSHELL=$!

# Get command PID
while : ; do
    PID=$( pgrep -P $SUBSHELL yes )
    test "$PID" = "" || break
    sleep 1
done

# Open pipe for writing
{ exec 4>finished.pipe ; while : ; do sleep 1000; done } &  

read -t 3 FINISHED <finished.pipe

if [ "$FINISHED" = finished ] ; then
  echo 'Subprocess finished'
else
  echo 'Subprocess timed out'
  kill $PID
fi

rm finished.pipe

Just posted my finished code for a similar project. It copies files of certain extensions in my code its pdf tif and tiff you can change them to whatever you want copied or delete the if statements if you only need 1 or 2 types. When a file is created or modified it gets the archive attribute this code also looks for that attribute and only copies it if it exists and then removes it after its copied so you dont copy unneeded files. It also has a log setup in it so that you will see a log of what time and day evetrything was transfered from the last time you ran the script. Hope it helps! the link is Error: Object Required; 'objDIR' Code: 800A01A8

This timer will fire a "Hello" alertbox after 30 seconds. However, everytime you click the reset timer button it clears the timerHandle then re-sets it again. Once it's fired, the game ends.

<script type="text/javascript">
    var timerHandle = setTimeout("alert('Hello')",3000);
    function resetTimer() {
        window.clearTimeout(timerHandle);
        timerHandle = setTimeout("alert('Hello')",3000);
    }
</script>

<body>
    <button onclick="resetTimer()">Reset Timer</button>
</body>

Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

This is my solution :

$(document).ready(function () {
  $( "td" ).on({
    "click": clicked,
    "mouseover": hovered,
    "mouseout": mouseout
});

var flag=0;

function hovered(){
  $(this).css("background", "#380606");
}

function mouseout(){
  if (flag == 0){
  $(this).css("background", "#ffffff");
} else {
  flag=0;
}
}

function clicked(){
  $(this).css("background","#000000");
  flag=1;
}
})

I use

if(is_numeric($value) && $value > 0 && $value == round($value, 0)){

to validate if a value is numeric, positive and integral

http://php.net/is_numeric

I don't really like ctype_digit as its not as readable as "is_numeric" and actually has less flaws when you really want to validate that a value is numeric.

Sometimes you want element.constructor.name

document.createElement('div').constructor.name
// HTMLDivElement

document.createElement('a').constructor.name
// HTMLAnchorElement

document.createElement('foo').constructor.name
// HTMLUnknownElement

Lockheed Martin uses a 3-prefix naming scheme which was wonderful to work with, especially when reading others' code.

   Scope          Reference Type(*Case-by-Case)   Type

   member   m     pointer p                       integer n
   argument a     reference r                     short   n
   local    l                                     float   f
                                                  double  f
                                                  boolean b

So...

int A::methodCall(float af_Argument1, int* apn_Arg2)
{
    lpn_Temp = apn_Arg2;
    mpf_Oops = lpn_Temp;  // Here I can see I made a mistake, I should not assign an int* to a float*
}

Take it for what's it worth.

To kill a session in Oracle, you use the ALTER SYSTEM KILL SESSION command.

As of PowerShell 6.0, Split-Path has an -Extenstion parameter. This means you can do:

$path | Split-Path -Extension

or

Split-Path -Path $path -Extension

For $path = "test.txt" both versions will return .txt, inluding the full stop.

An alternative solution:

div[class|='tocolor'] will match for values of the "class" attribute that begin with "tocolor-", including "tocolor-1", "tocolor-2", etc.

Beware that this won't match

<div class="foo tocolor-">

Reference: https://www.w3.org/TR/css3-selectors/#attribute-representation

[att|=val]

Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D)
