Added another case to Michal Górny's answer:

Note that relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application must always use absolute imports.

(apply on Mac, and probably other Unixes)

Actually there is a problem with the wc approach: it does not count the last line if it does not terminate with the end of line symbol.

Use this instead

nbLines=$(cat -n file.txt | tail -n 1 | cut -f1 | xargs)

or even better (thanks gniourf_gniourf):

nblines=$(grep -c '' file.txt)

Note: The awk approach by chilicuil also works.

Kotlin

For those using Kotlin who are following the docs package conventions:

In pure Kotlin projects, the recommended directory structure is to follow the package structure with the common root package omitted (e.g. if all the code in the project is in the "org.example.kotlin" package and its subpackages, files with the "org.example.kotlin" package should be placed directly under the source root, and files in "org.example.kotlin.foo.bar" should be in the "foo/bar" subdirectory of the source root).

IntelliJ doesn't support this yet. The only thing you can do is to disable this warning, and accept that the IDE will not help you with refactorings when it comes to changing folders/files structures.

It's only another way to do it but it helped me a lot so I write it here:

Having this data structure:

X=[1,2,3,4]
Y=['a','b','c','d']
XY=zip(X,Y)

Resulting in:

In: XY
Out: [(1, 'a'), (2, 'b'), (3, 'c'), (4, 'd')]

The more pythonic way to unzip it and go back to the original is this one in my opinion:

x,y=zip(*XY)

But this return a tuple so if you need a list you can use:

x,y=(list(x),list(y))

This seemed to have worked for me!

Mat a_image = imread(argv[1]);

cvtColor(a_image, a_image, CV_BGR2GRAY);
GaussianBlur(a_image, a_image, Size(7,7), 1.5, 1.5);
threshold(a_image, a_image, 100, 255, CV_THRESH_BINARY);

Aside from using %, age of empires III to lower case is age of empires iii so your query should be:

select *
from games
where lower(title) like 'age of empires iii%'

You can use numpy:

import numpy as np

Example from Empty Array:

np.empty([2, 2])
array([[ -9.74499359e+001,   6.69583040e-309],
       [  2.13182611e-314,   3.06959433e-309]])  

-- Sql Server 2005 Management studio

use Master
go
DECLARE @MyVar bigint
SET @myvar = (SELECT count(*) FROM spt_values);
SELECT @myvar

Result: 2346 (in my db)

-- Note: @myvar = @Myvar

Is the following acceptable:

$('#myTableRow').remove();

MSBuild in an independent build tool that is frequently bundled with other tools. It may have been installed on your computer with .NET (older versions), Visual Studio (newer versions), or even Team Foundation Build.

MSBuild needs configuration files, compilers, etc (a ToolSet) that matches the version of Visual Studio or TFS that will use it, as well as the version of .NET against which source code will be compiled.

Depending on how MSBuild was installed, the configuration files may be in one or more of these paths.

• C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\
• C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\
• C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\

As described in other answers, a registry item and/or environmental variable point must to the ToolSet path.

• The VCTargetsPath key under HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0
• The VCTargetsPath environmental variable.

Occasionally, an operation like installing a tool will leave the registry and/or environmental variable set incorrectly. The other answers are all variations on fixing them.

The only thing I have to add is the environmental variable didn't work for me when I left off the trailing \

The easy way is to define a non-ASCII character... as a character that is not an ASCII character.

LC_ALL=C grep '[^ -~]' file.xml

Add a tab after the ^ if necessary.

Setting LC_COLLATE=C avoids nasty surprises about the meaning of character ranges in many locales. Setting LC_CTYPE=C is necessary to match single-byte characters — otherwise the command would miss invalid byte sequences in the current encoding. Setting LC_ALL=C avoids locale-dependent effects altogether.

If you don't encounter any permission errors with

Working with VS 2013. Try the following

Tools -> Options -> Debugging -> Output Window -> Module Load Messages -> Off

It will disable the display of modules loaded.

A place where alloca() is especially dangerous than malloc() is the kernel - kernel of a typical operating system has a fixed sized stack space hard-coded into one of its header; it is not as flexible as the stack of an application. Making a call to alloca() with an unwarranted size may cause the kernel to crash. Certain compilers warn usage of alloca() (and even VLAs for that matter) under certain options that ought to be turned on while compiling a kernel code - here, it is better to allocate memory in the heap that is not fixed by a hard-coded limit.

If you are using Linux OS:

1. Remove matplotlib==1.3.1 from requirements.txt
2. Try to install with sudo apt-get install python-matplotlib
3. Run pip install -r requirements.txt (Python 2), or pip3 install -r requirements.txt (Python 3)
4. pip freeze > requirements.txt

If you are using Windows OS:

1. python -m pip install -U pip setuptools
2. python -m pip install matplotlib

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

Here is another way to change timezone in datetime format (I know I wasted my energy on this but I didn't see this page so I don't know how) without min. and sec. cause I don't need it for my project:

def change_time_zone(year, month, day, hour):
      hour = hour + 7 #<-- difference
      if hour >= 24:
        difference = hour - 24
        hour = difference
        day += 1
        long_months = [1, 3, 5, 7, 8, 10, 12]
        short_months = [4, 6, 9, 11]
        if month in short_months:
          if day >= 30:
            day = 1
            month += 1
            if month > 12:
              year += 1
        elif month in long_months:
          if day >= 31:
            day = 1
            month += 1
            if month > 12:
              year += 1
        elif month == 2:
          if not year%4==0:

I am getting the same error Due to following reason.

I have entered right credentials but with copy-paste. So that may b issue of junk characters insertion while copy paste. I have entered manually and ran the code and now its working fine

Thank You

Below is a solution from here

Sub stance()
Dim x As Long

For x = 1 To 10    
    Debug.Print x
Next

Debug.Print Now
Application.SendKeys "^g ^a {DEL}"    
End Sub

Yes there is:

UPDATE
As of 10 of April 2018, this code still works.
Some users reported "not working", if it doesn't work for you, please read below:

From what I've learned, the problem is related with network speed and or screen size.
When YT player starts, it collects the network speed, screen and player sizes, among other information, if the connection is slow or the screen/player size smaller than the quality requested(vq=), a lower quality video is displayed despite the option selected on vq=.

Also make sure you read the comments below.

For me the problem got solved by simply reinstalling mysql-python

pip uninstall mysql-python
pip install mysql-python

The ActiveDirectory module for powershell can be installed by adding the RSAT-AD-Powershell feature.

In an elevated powershell window:

Add-WindowsFeature RSAT-AD-PowerShell

or

Enable-WindowsOptionalFeature -FeatureName ActiveDirectory-Powershell -Online -All

There is now a new way of addressing this issue - if you remove position: relative from the container which needs to have the overflow-y visible, you can have overflow-y visible and overflow-x hidden, and vice versa (have overflow-x visible and overflow-y hidden, just make sure the container with the visible property is not relatively positioned).

See this post from CSS Tricks for more details - it worked for me: https://css-tricks.com/popping-hidden-overflow/

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

Composition API

Template refs section tells how this has been unified:

• within template, use ref="myEl"; :ref= with a v-for
• within script, have a const myEl = ref(null) and expose it from setup

The reference carries the DOM element from mounting onwards.

Try the following parameter:

-nc, --no-clobber: skip downloads that would download to existing files.

Sample usage:

wget -nc http://example.com/pic.png

I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:

1 - Enable TCP/IP

We can enable TCP/IP protocol with WMI:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocol " _
    & "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")

if tcpProtocols.Count = 1 then
    ' set tcpProtocol = tcpProtocols(0)
    ' I wish this worked, but unfortunately 
    ' there's no int-indexed Item property in this type

    ' Doing this instead
    for each tcpProtocol in tcpProtocols
        dim setEnableResult
            setEnableResult = tcpProtocol.SetEnable()
            if setEnableResult <> 0 then 
                Wscript.Echo "Failed!"
            end if
    next
end if

2 - Open the right ports in the firewall

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)

3 - Modify TCP/IP properties enable a IP address

We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocolProperty " _
    & "where InstanceName='SQLEXPRESS' and " _
    & "ProtocolName='Tcp' and IPAddressName='IPAll'")

for each tcpProperty in tcpProperties
    dim setValueResult, requestedValue

    if tcpProperty.PropertyName = "TcpPort" then
        requestedValue = "3456"
    elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
        requestedValue = ""
    end if

    setValueResult = tcpProperty.SetStringValue(requestedValue)
    if setValueResult = 0 then 
        Wscript.Echo "" & tcpProperty.PropertyName & " set."
    else
        Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
    end if
next

Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.

Just a reminder that when working with WMI, WBEMTest.exe is your best friend!

4 - Enable mixed mode authentication in sql server

I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:

1. Use LoginMode property of Microsoft.SqlServer.Management.Smo.Server class, as described here.

2. Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS, so for my SQL Server 2008 R2 Express instance the right registry key was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer.

5 - Change user (sa) default password

You got this one covered.

6 - Finally (connect to the instance)

Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.

SQLCMD -U sa -P newPassword -S 192.168.0.120,3456

Please let me know if this works for you (fingers crossed!).

you can also use this function.

 public static void GetGridSelectedView(out string tuid, ref DataGrid dataGrid,string Column)
    {
        try
        {
            // grid selected row values
            var item = dataGrid.SelectedItem as DataRowView;
            if (null == item) tuid = null;
            if (item.DataView.Count > 0)
            {
                tuid =  item.DataView[dataGrid.SelectedIndex][Column].ToString().Trim();
            }
            else { tuid = null; }
        }
        catch (Exception exc) { System.Windows.MessageBox.Show(exc.Message); tuid = null; }
    }

I tried in online compiler https://www.onlinegdb.com/online_c++_compiler

int main()
{
    cout<<"Hello World";
    int x = 10;
    int *p = &x;
    printf("\nAddress of x is %p\n", &x); // 0x7ffc7df0ea54
    printf("Address of p is %p\n", p);    // 0x7ffc7df0ea54

    return 0;
}

I am not able to add a comment to M. Kiewisch since I do not have enough reputation points (only have 41 but need more than 50 to comment).

Anyway, just want to point out that M. Kiewisch solution does not work as is and may need more tweaking. Consider for example

>>> df = pd.DataFrame({'a': [1, 2, 3, 5], 'b': [4, np.NaN, 6, 4]})
>>> df
   a    b
0  1  4.0
1  2  NaN
2  3  6.0
3  5  4.0
>>> df.groupby(['b']).sum()
     a
b
4.0  6
6.0  3
>>> df.astype(str).groupby(['b']).sum()
      a
b
4.0  15
6.0   3
nan   2

which shows that for group b=4.0, the corresponding value is 15 instead of 6. Here it is just concatenating 1 and 5 as strings instead of adding it as numbers.

Optimization for emplace_back can be demonstrated in next example.

For emplace_back constructor A (int x_arg) will be called. And for push_back A (int x_arg) is called first and move A (A &&rhs) is called afterwards.

Of course, the constructor has to be marked as explicit, but for current example is good to remove explicitness.

#include <iostream>
#include <vector>
class A
{
public:
  A (int x_arg) : x (x_arg) { std::cout << "A (x_arg)\n"; }
  A () { x = 0; std::cout << "A ()\n"; }
  A (const A &rhs) noexcept { x = rhs.x; std::cout << "A (A &)\n"; }
  A (A &&rhs) noexcept { x = rhs.x; std::cout << "A (A &&)\n"; }

private:
  int x;
};

int main ()
{
  {
    std::vector<A> a;
    std::cout << "call emplace_back:\n";
    a.emplace_back (0);
  }
  {
    std::vector<A> a;
    std::cout << "call push_back:\n";
    a.push_back (1);
  }
  return 0;
}

output:

call emplace_back:
A (x_arg)

call push_back:
A (x_arg)
A (A &&)

I had a similar situation when reading from Oracle in a Spark job. This connection reset error was caused by an incompatibility between the Oracle server and the JDBC driver used. Worth checking it.

 DECLARE @SQL AS VARCHAR(8000)

showInventory(player); is passing a type as parameter. That's illegal, you need to pass an object.

For example, something like:

player p;
showInventory(p);  

I'm guessing you have something like this:

int main()
{
   player player;
   toDo();
}

which is awful. First, don't name the object the same as your type. Second, in order for the object to be visible inside the function, you'll need to pass it as parameter:

int main()
{
   player p;
   toDo(p);
}

and

std::string toDo(player& p) 
{
    //....
    showInventory(p);
    //....
}

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

You aren't creating any buttons, you just have an empty list.

You can forget the list and just create the buttons in the loop.

private void button1_Click(object sender, EventArgs e) 
{     
     int top = 50;
     int left = 100;

     for (int i = 0; i < 10; i++)     
     {         
          Button button = new Button();   
          button.Left = left;
          button.Top = top;
          this.Controls.Add(button);      
          top += button.Height + 2;
     }
} 

Versions of IE before IE9 don't have an .indexOf() function for Array, to define the exact spec version, run this before trying to use it:

if (!Array.prototype.indexOf)
{
  Array.prototype.indexOf = function(elt /*, from*/)
  {
    var len = this.length >>> 0;

    var from = Number(arguments[1]) || 0;
    from = (from < 0)
         ? Math.ceil(from)
         : Math.floor(from);
    if (from < 0)
      from += len;

    for (; from < len; from++)
    {
      if (from in this &&
          this[from] === elt)
        return from;
    }
    return -1;
  };
}

This is the version from MDN, used in Firefox/SpiderMonkey. In other cases such as IE, it'll add .indexOf() in the case it's missing... basically IE8 or below at this point.

Sometimes passing parameters in the main method causes this problem eg. public static void main(String[] args,int a). If you declare the variable outside the main method, it might help :)

I dont get it clearly, do you want to link an external css as the structure of files you defined above? If yes then just use the link tag :

    <link rel="stylesheet" type="text/css" href="file.css">

so basically for files that are under your website folder (folder containing your index) you directly call it. For each successive folder use the "/" for example in your case :

    <link rel="stylesheet" type="text/css" href="Fonts/Font1/file name">
    <link rel="stylesheet" type="text/css" href="Fonts/Font2/file name">

Yes, you can use the *args (splat) syntax:

function_that_needs_strings(*my_list)

where my_list can be any iterable; Python will loop over the given object and use each element as a separate argument to the function.

See the call expression documentation.

There is a keyword-parameter equivalent as well, using two stars:

kwargs = {'foo': 'bar', 'spam': 'ham'}
f(**kwargs)

and there is equivalent syntax for specifying catch-all arguments in a function signature:

def func(*args, **kw):
    # args now holds positional arguments, kw keyword arguments

I found this on the Bootstrap website, but it really isn't a Bootstrap class, it's just HTML.

<strong>rendered as bold text</strong>

If you don't want add the /s regex modifier (perhaps you still want . to retain its original meaning elsewhere in the regex), you may also use a character class. One possibility:

[\S\s]

a character which is not a space or is a space. In other words, any character.

You can also change modifiers locally in a small part of the regex, like so:

(?s:.)

You can get the example of css implemented html to pdf conversion using jspdf on following link: JSFiddle Link

This is sample code for the jspdf html to pdf download.

$('#print-btn').click(() => {
    var pdf = new jsPDF('p','pt','a4');
    pdf.addHTML(document.body,function() {
        pdf.save('web.pdf');
    });
})

Surround what you want to be bold with:

<span style="font-weight:bold">Your bold text</span>

This would go inside your <td> tag.

  <script>
function equalHeight(group) {
   tallest = 0;
   group.each(function() {
      thisHeight = $(this).height();
      if(thisHeight > tallest) {
         tallest = thisHeight;
      }
   });
   group.height(tallest);
}
$(document).ready(function() {
   equalHeight($(".column"));
});
</script>

timer.scheduleAtFixedRate( new Task(), 1000,3000); 

Check out Awesome Print. Parse the JSON string into a Ruby Hash, then display it with ap like so:

require "awesome_print"
require "json"

json = '{"holy": ["nested", "json"], "batman!": {"a": 1, "b": 2}}'

ap(JSON.parse(json))

With the above, you'll see:

{
  "holy" => [
    [0] "nested",
    [1] "json"
  ],
  "batman!" => {
    "a" => 1,
    "b" => 2
  }
}

Awesome Print will also add some color that Stack Overflow won't show you.

After trying a few of the above suggestions without success (Swift versions...) I ended up using the official documentation: https://developer.apple.com/documentation/foundation/url_loading_system/downloading_files_from_websites

let downloadTask = URLSession.shared.downloadTask(with: url) {
    urlOrNil, responseOrNil, errorOrNil in
    // check for and handle errors:
    // * errorOrNil should be nil
    // * responseOrNil should be an HTTPURLResponse with statusCode in 200..<299
    
    guard let fileURL = urlOrNil else { return }
    do {
        let documentsURL = try
            FileManager.default.url(for: .documentDirectory,
                                    in: .userDomainMask,
                                    appropriateFor: nil,
                                    create: false)
        let savedURL = documentsURL.appendingPathComponent(fileURL.lastPathComponent)
        try FileManager.default.moveItem(at: fileURL, to: savedURL)
    } catch {
        print ("file error: \(error)")
    }
}
downloadTask.resume()

Yes, with set_index you can make Locality your row index.

data.set_index('Locality', inplace=True)

If inplace=True is not provided, set_index returns the modified dataframe as a result.

Example:

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

Note that double quotes strings escape \'s.

'C:\projects\blah.dll'.split('\\').last

export default class MyComponent extends React.Component {

onSubmit(e) {
    e.preventDefault();
    var title = this.title.value; //added .value
    console.log(title);
}

render(){
    return (
        ...
        <form className="form-horizontal">
            ...
            <input type="text" className="form-control" ref={input => this.title = input} name="title" />
            ...
        </form>
        ...
        <button type="button" onClick={this.onSubmit} className="btn">Save</button>
        ...
    );
}

};

The for loop iterates over the elements of the array, not its indexes. Suppose you have a list ar = [2, 4, 6]:

When you iterate over it with for i in ar: the values of i will be 2, 4 and 6. So, when you try to access ar[i] for the first value, it might work (as the last position of the list is 2, a[2] equals 6), but not for the latter values, as a[4] does not exist.

If you intend to use indexes anyhow, try using for index, value in enumerate(ar):, then theSum = theSum + ar[index] should work just fine.

Overloading: In Real world, overloading means assigning some extra stuff to someone. As as in real world Overloading in PHP means calling extra functions. In other way You can say it have slimier function with different parameter.In PHP you can use overloading with magic functions e.g. __get, __set, __call etc.

Example of Overloading:

class Shape {
   const Pi = 3.142 ;  // constant value
  function __call($functionname, $argument){
    if($functionname == 'area')
    switch(count($argument)){
        case 0 : return 0 ;
        case 1 : return self::Pi * $argument[0] ; // 3.14 * 5
        case 2 : return $argument[0] * $argument[1];  // 5 * 10
    }

  }

 }
 $circle = new Shape();`enter code here`
 echo "Area of circle:".$circle->area()."</br>"; // display the area of circle Output 0
 echo "Area of circle:".$circle->area(5)."</br>"; // display the area of circle
 $rect = new Shape();
 echo "Area of rectangle:".$rect->area(5,10); // display area of rectangle

Overriding : In object oriented programming overriding is to replace parent method in child class.In overriding you can re-declare parent class method in child class. So, basically the purpose of overriding is to change the behavior of your parent class method.

Example of overriding :

class parent_class
{

  public function text()    //text() is a parent class method
  {
    echo "Hello!! everyone I am parent class text method"."</br>";
  }
  public function test()   
  {
    echo "Hello!! I am second method of parent class"."</br>";
  }

}

class child extends parent_class
{
  public function text()     // Text() parent class method which is override by child 
  class
  {
    echo "Hello!! Everyone i am child class";
  }

 }

 $obj= new parent_class();
 $obj->text();            // display the parent class method echo
 $obj= new parent_class();
 $obj->test();
 $obj= new child();
 $obj->text(); // display the child class method echo

Add this script inside head tag:

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>

Great piece of code, thanks for sharing!

I ended up using reflection to get the actual DataMemberName to throw back to a client on an error (I'm using bulk save in a WCF service). Hopefully someone else will find how I did it useful.

static string GetDataMemberName(string colName, object t) {_x000D_
  foreach(PropertyInfo propertyInfo in t.GetType().GetProperties()) {_x000D_
    if (propertyInfo.CanRead) {_x000D_
      if (propertyInfo.Name == colName) {_x000D_
        var attributes = propertyInfo.GetCustomAttributes(typeof(DataMemberAttribute), false).FirstOrDefault() as DataMemberAttribute;_x000D_
        if (attributes != null && !string.IsNullOrEmpty(attributes.Name))_x000D_
          return attributes.Name;_x000D_
        return colName;_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
  return colName;_x000D_
}

From the spring specs, there are five types of bean scopes supported :

1. singleton(default*)

Scopes a single bean definition to a single object instance per Spring IoC container.

2. prototype

Scopes a single bean definition to any number of object instances.

3. request

Scopes a single bean definition to the lifecycle of a single HTTP request; that is each and every HTTP request will have its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext.

4. session

Scopes a single bean definition to the lifecycle of a HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext.

5. global session

Scopes a single bean definition to the lifecycle of a global HTTP Session. Typically only valid when used in a portlet context. Only valid in the context of a web-aware Spring ApplicationContext.

*default means when no scope is explicitly provided in the <bean /> tag. read more about them here: http://static.springsource.org/spring/docs/3.0.0.M3/reference/html/ch04s04.html

For UTF-8 textual information, you should use utf8_general_ci because...

• utf8_bin: compare strings by the binary value of each character in the string

• utf8_general_ci: compare strings using general language rules and using case-insensitive comparisons

a.k.a. it will should making searching and indexing the data faster/more efficient/more useful.

var xInt = parseInt(x)

This will return either the integer value, or NaN.

Read more about parseInt here.

append( ) function and spread operator

Two slices can be concatenated using append method in the standard golang library. Which is similar to the variadic function operation. So we need to use ...

package main

import (
    "fmt"
)

func main() {
    x := []int{1, 2, 3}
    y := []int{4, 5, 6}
    z := append([]int{}, append(x, y...)...)
    fmt.Println(z)
}

output of the above code is: [1 2 3 4 5 6]

There are several ways in which you can set the timeout for php-fpm. In /etc/php5/fpm/pool.d/www.conf I added this line:

request_terminate_timeout = 180

Also, in /etc/nginx/sites-available/default I added the following line to the location block of the server in question:

fastcgi_read_timeout 180;

The entire location block looks like this:

location ~ \.php$ {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_read_timeout 180;
    include fastcgi_params;
} 

Now just restart php-fpm and nginx and there should be no more timeouts for requests taking less than 180 seconds.

Along the same lines as some of the suggestions you would need to do at least the following:

• Load some CSS dynamically through JavaScript
• Craft some print-specific CSS rules
• Apply your fancy CSS rules through JavaScript

An example CSS could be as simple as this:

@media print {
  body * {
    display:none;
  }

  body .printable {
    display:block;
  }
}

Your JavaScript would then only need to apply the "printable" class to your target div and it will be the only thing visible (as long as there are no other conflicting CSS rules -- a separate exercise) when printing happens.

<script type="text/javascript">
  function divPrint() {
    // Some logic determines which div should be printed...
    // This example uses div3.
    $("#div3").addClass("printable");
    window.print();
  }
</script>

You may want to optionally remove the class from the target after printing has occurred, and / or remove the dynamically-added CSS after printing has occurred.

Below is a full working example, the only difference is that the print CSS is not loaded dynamically. If you want it to really be unobtrusive then you will need to load the CSS dynamically like in this answer.

Your question did not indicate if order or distinct values are a requirement.

If you don't care about order, and will not have the same value in the container more than once, use a Set. It will be way faster, and more succinct.

var aSet = new Set();

aSet.add(1);
aSet.add(2);
aSet.add(3);

aSet.delete(2);

As of Oracle 9i, you can use CONNECT BY.

SELECT LPAD(' ', (LEVEL - 1) * 4) || "Name" AS "Name"
FROM (SELECT * FROM TMP_NODE ORDER BY "Order")
CONNECT BY PRIOR "Id" = "ParentId"
START WITH "Id" IN (SELECT "Id" FROM TMP_NODE WHERE "ParentId" = 0)

As of SQL Server 2005, you can use a recursive common table expression (CTE).

WITH [NodeList] (
  [Id]
  , [ParentId]
  , [Level]
  , [Order]
) AS (
  SELECT [Node].[Id]
    , [Node].[ParentId]
    , 0 AS [Level]
    , CONVERT([varchar](MAX), [Node].[Order]) AS [Order]
  FROM [Node]
  WHERE [Node].[ParentId] = 0
  UNION ALL
  SELECT [Node].[Id]
    , [Node].[ParentId]
    , [NodeList].[Level] + 1 AS [Level]
    , [NodeList].[Order] + '|'
      + CONVERT([varchar](MAX), [Node].[Order]) AS [Order]
  FROM [Node]
    INNER JOIN [NodeList] ON [NodeList].[Id] = [Node].[ParentId]
) SELECT REPLICATE(' ', [NodeList].[Level] * 4) + [Node].[Name] AS [Name]
FROM [Node]
  INNER JOIN [NodeList] ON [NodeList].[Id] = [Node].[Id]
ORDER BY [NodeList].[Order]

Both will output the following results.

Name
'Node 1'
'    Node 1.1'
'        Node 1.1.1'
'    Node 1.2'
'Node 2'
'    Node 2.1'

<input id="typeahead-input" type="text" data-provide="typeahead" />

<script type="text/javascript">
var data = ["Aamir", "Amol", "Ayesh", "Sameera", "Sumera", "Kajol", "Kamal",
  "Akash", "Robin", "Roshan", "Aryan"];
$(function() {
    $('#typeahead-input').typeahead({
        source: function (query, process) {
               process(data);
            });
        }
    });
});
</script>

to convert a TimestampTZ in oracle, you do

TO_TIMESTAMP_TZ('2012-10-09 1:10:21 CST','YYYY-MM-DD HH24:MI:SS TZR') 
  at time zone 'region'

see here: http://docs.oracle.com/cd/E11882_01/server.112/e10729/ch4datetime.htm#NLSPG264

and here for regions: http://docs.oracle.com/cd/E11882_01/server.112/e10729/applocaledata.htm#NLSPG0141

Jeff Atwood has a recent blog post about this: The Great Newline Schism

Here is the essence from Wikipedia:

The sequence CR+LF was in common use on many early computer systems that had adopted teletype machines, typically an ASR33, as a console device, because this sequence was required to position those printers at the start of a new line. On these systems, text was often routinely composed to be compatible with these printers, since the concept of device drivers hiding such hardware details from the application was not yet well developed; applications had to talk directly to the teletype machine and follow its conventions. The separation of the two functions concealed the fact that the print head could not return from the far right to the beginning of the next line in one-character time. That is why the sequence was always sent with the CR first. In fact, it was often necessary to send extra characters (extraneous CRs or NULs, which are ignored) to give the print head time to move to the left margin. Even after teletypes were replaced by computer terminals with higher baud rates, many operating systems still supported automatic sending of these fill characters, for compatibility with cheaper terminals that required multiple character times to scroll the display.

I guess the verdict is i cannot programmatically uniquely identify a computer which is visiting my web site.

I have the following question. When i use a machine which has never visited my online banking web site i get asked for additional authentification. then, if i go back a second time to the online banking site i dont get asked the additional authentification. reading the answers to my question i decided it must be a cookie involved. therefore, i deleted all cookies in IE and relogged onto my online banking site fully expecting to be asked the authentification questions again. to my surprise i was not asked. doesnt this lead one to believe the bank is doing some kind of pc tagging which doesnt involve cookies?

further, after much googling today i found the following company who claims to sell a solution which does uniquely identify machines which visit a web site. http://www.the41.com/products.asp.

i appreciate all the good information if you could clarify further this conflicting information i found i would greatly appreciate it.

I bashed my head on this for hours until I thought about checking my .bash_profile. I didn't have a path listed for python3 so I added the following code:

# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH

And then re-installed matplotlib with sudo pip3 install matplotlib. All is working beautifully now.

Here is the analysis in the book Data Structures and Algorithm Analysis in C by Mark Allen Weiss (second edition, 2.4.4):

Euclid's algorithm works by continually computing remainders until 0 is reached. The last nonzero remainder is the answer.

Here is the code:

unsigned int Gcd(unsigned int M, unsigned int N)
{

    unsigned int Rem;
    while (N > 0) {
        Rem = M % N;
        M = N;
        N = Rem;
    }
    Return M;
}

Here is a THEOREM that we are going to use:

If M > N, then M mod N < M/2.

PROOF:

There are two cases. If N <= M/2, then since the remainder is smaller than N, the theorem is true for this case. The other case is N > M/2. But then N goes into M once with a remainder M - N < M/2, proving the theorem.

So, we can make the following inference:

Variables    M      N      Rem

initial      M      N      M%N

1 iteration  N     M%N    N%(M%N)

2 iterations M%N  N%(M%N) (M%N)%(N%(M%N)) < (M%N)/2

So, after two iterations, the remainder is at most half of its original value. This would show that the number of iterations is at most 2logN = O(logN).

Note that, the algorithm computes Gcd(M,N), assuming M >= N.(If N > M, the first iteration of the loop swaps them.)

SELECT CONVERT(NVARCHAR(10), PaymentDate, 120) [Month], SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY CONVERT(NVARCHAR(10), PaymentDate, 120)
ORDER BY [Month]

You could also try:

SELECT DATEPART(Year, PaymentDate) Year, DATEPART(Month, PaymentDate) Month, SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY DATEPART(Year, PaymentDate), DATEPART(Month, PaymentDate)
ORDER BY Year, Month

My problem was slightly different. I did everything right. But I was inheriting the wrong class for the activity hosting the fragment.

So to be clear, if you are overriding onCreateOptionsMenu(Menu menu, MenuInflater inflater) in the fragment, make sure your activity class which hosts this fragment inherits android.support.v7.app.ActionBarActivity (in case you would want to support below API level 11).

I was inheriting the android.support.v4.app.FragmentActivity to support API level below 11.

Use ThenByDescending:

var hold = MyList.OrderBy(x => x.StartDate)
                 .ThenByDescending(x => x.EndDate)
                 .ToList();

You can also use query syntax and say:

var hold = (from x in MyList
           orderby x.StartDate, x.EndDate descending
           select x).ToList();

ThenByDescending is an extension method on IOrderedEnumerable which is what is returned by OrderBy. See also the related method ThenBy.

Check to make sure there is a film release date; if the date is missing you will not be able to format on a non-object.

if ($info['Film_Release']){ //check if the date exists
   $dateFromDB = $info['Film_Release'];
   $newDate = DateTime::createFromFormat("l dS F Y", $dateFromDB);
   $newDate = $newDate->format('d/m/Y'); 
} else {
   $newDate = "none"; 
}

or

 $newDate = ($info['Film_Release']) ? DateTime::createFromFormat("l dS F Y", $info['Film_Release'])->format('d/m/Y'): "none" 

You may use Json.Net framework to do this. Just like this :

Account account = JsonConvert.DeserializeObject<Account>(json);

the home page : http://json.codeplex.com/

the document about this : http://james.newtonking.com/json/help/index.html#

Works fine for me... The tr:hover should work. Probably it won't work because:

1. The background color you have set is very light. You don't happen to use this on a white background, do you?

2. Your <td> tags are not closed properly.

Please note that hovering a <tr> will not work in older browsers.

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

Load testing your API by using just ab is not enough. However, I think it's a great tool to give you a basic idea how your site is performant.

If you want to use the ab command in to test multiple API endpoints, with different data, all at the same time in background, you need to use "nohup" command. It runs any command even when you close the terminal.

I wrote a simple script that automates the whole process, feel free to use it: http://blog.ikvasnica.com/entry/load-test-multiple-api-endpoints-concurrently-use-this-simple-shell-script

Unfortunately, you can't do that. I believe it would be useful, though. It is more natural to type:

DateTime.Tomorrow

than:

DateTimeUtil.Tomorrow

With a Util class, you have to check for the existence of a static method in two different classes, instead of one.

After some tinkering for a while with different solutions i found out that one must create a notification channel in Android 8.1 and above.

private fun startForeground() {
    val channelId =
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                createNotificationChannel("my_service", "My Background Service")
            } else {
                // If earlier version channel ID is not used
                // https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#NotificationCompat.Builder(android.content.Context)
                ""
            }

    val notificationBuilder = NotificationCompat.Builder(this, channelId )
    val notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setPriority(PRIORITY_MIN)
            .setCategory(Notification.CATEGORY_SERVICE)
            .build()
    startForeground(101, notification)
}

@RequiresApi(Build.VERSION_CODES.O)
private fun createNotificationChannel(channelId: String, channelName: String): String{
    val chan = NotificationChannel(channelId,
            channelName, NotificationManager.IMPORTANCE_NONE)
    chan.lightColor = Color.BLUE
    chan.lockscreenVisibility = Notification.VISIBILITY_PRIVATE
    val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    service.createNotificationChannel(chan)
    return channelId
}

From my understanding background services are now displayed as normal notifications that the user then can select to not show by deselecting the notification channel.

Update: Also don't forget to add the foreground permission as required Android P:

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

As the title says "Best way", I think it's a good idea to consider the patience merge strategy.

From: https://git-scm.com/docs/merge-strategies

With this option, 'merge-recursive' spends a little extra time to avoid mismerges that sometimes occur due to unimportant matching lines (e.g., braces from distinct functions). Use this when the branches to be merged have diverged wildly. See also git-diff[1] --patience.

Usage:

git fetch
git merge -s recursive -X patience origin/master

Git Alias

I use always an alias for this, e.g. run once:

 git config --global alias.pmerge 'merge -s recursive -X patience'

Now you could do:

git fetch
git pmerge origin/master

Best , Easiest and Generic Answer :).

    string originalString = "1111222233334444";
    List<string> test = new List<string>();
    int chunkSize = 4; // change 4 with the size of strings you want.
    for (int i = 0; i < originalString.Length; i = i + chunkSize)
    {
        if (originalString.Length - i >= chunkSize)
            test.Add(originalString.Substring(i, chunkSize));
        else
            test.Add(originalString.Substring(i,((originalString.Length - i))));
    }

There is also another reason. In my case, I had copy an index.cshtml file to web root folder (outside the Views folder) as a backup from remote server.

So, I kept changing my /views/web.config, kept changing my /views/home/index.cshtml and error kept happening... until found out the /index.cshtml outside the views folder, deleted it and sure, it all went back to normal!

For checking the version of scikit-learn in shell script, if you have pip installed, you can try this command

pip freeze | grep scikit-learn
scikit-learn==0.17.1

Hope it helps!

        Header header = new Header();
        Byte[] headerBytes = new Byte[Marshal.SizeOf(header)];
        Marshal.Copy((IntPtr)(&header), headerBytes, 0, headerBytes.Length);

This should do the trick quickly, right?

How about this? I needed the exact same thing, I had to create one from scratch. It's PURE CSS, and works in IE9+ Feel-free to improve upon it.

Demo: http://www.d-k-j.com/Articles/Web_Development/Pure_CSS_5_Star_Rating_System_with_Radios/

<ul class="form">
    <li class="rating">
        <input type="radio" name="rating" value="0" checked /><span class="hide"></span>
        <input type="radio" name="rating" value="1" /><span></span>
        <input type="radio" name="rating" value="2" /><span></span>
        <input type="radio" name="rating" value="3" /><span></span>
        <input type="radio" name="rating" value="4" /><span></span>
        <input type="radio" name="rating" value="5" /><span></span>
    </li>
</ul>

CSS:

.form {
    margin:0;
}

.form li {
    list-style:none;
}

.hide {
    display:none;
}

.rating input[type="radio"] {
    position:absolute;
    filter:alpha(opacity=0);
    -moz-opacity:0;
    -khtml-opacity:0;
    opacity:0;
    cursor:pointer;
    width:17px;
}

.rating span {
    width:24px;
    height:16px;
    line-height:16px;
    padding:1px 22px 1px 0; /* 1px FireFox fix */
    background:url(stars.png) no-repeat -22px 0;
}

.rating input[type="radio"]:checked + span {
    background-position:-22px 0;
}

.rating input[type="radio"]:checked + span ~ span {
    background-position:0 0;
}

I also got

SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect datetime value: '0000-00-00 00:00:00' for column

error info

Fix this by changing 0000-00-00 00:00:00 to 1970-01-01 08:00:00

1970-01-01 08:00:00 unix timestamp is 0

Simply, App.config is an XML based file format that holds the Application Level Configurations.

Example:

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="key" value="test" />
  </appSettings>
</configuration>

You can access the configurations by using ConfigurationManager as shown in the piece of code snippet below:

var value = System.Configuration.ConfigurationManager.AppSettings["key"];
// value is now "test"

Note: ConfigurationSettings is obsolete method to retrieve configuration information.

var value = System.Configuration.ConfigurationSettings.AppSettings["key"];

This error was caused, for me, by different circumstances. A downloaded project tutorial had a default setting of [Project]>Targets>Build Settings>Architectures>Build Active Architecture Only>Release = "Yes." I wasn't intending to build a release, so the solution was to set Release (which presumably requires not just a developer profile but distribution profile) to "No."

Simple assigning to window.location or window.location.href should be fine:

window.location = newUrl;

However, your new URL will cause the browser to load the new page, but it sounds like you'd like to modify the URL without leaving the current page. You have two options for this:

1. Use the URL hash. For example, you can go from example.com to example.com#foo without loading a new page. You can simply set window.location.hash to make this easy. Then, you should listen to the HTML5 hashchange event, which will be fired when the user presses the back button. This is not supported in older versions of IE, but check out jQuery BBQ, which makes this work in all browsers.

2. You could use HTML5 History to modify the path without reloading the page. This will allow you to change from example.com/foo to example.com/bar. Using this is easy:

   window.history.pushState("example.com/foo");

   When the user presses "back", you'll receive the window's popstate event, which you can easily listen to (jQuery):

   $(window).bind("popstate", function(e) { alert("location changed"); });

   Unfortunately, this is only supported in very modern browsers, like Chrome, Safari, and the Firefox 4 beta.

Atomic collections are accessible by $

Recursive collections are not. Rather the [[ ]] is used

 Browse[1]> is.atomic(list())
 [1] FALSE

 Browse[1]> is.atomic(data.frame())
 [1] FALSE

 Browse[1]> is.atomic(class(list(foo="bar")))
 [1] TRUE

 Browse[1]> is.atomic(c(" lang "))
 [1] TRUE

R can be funny sometimes

 a = list(1,2,3)
 b = data.frame(a)
 d = rbind("?",c(b))
 e = exp(1)
 f = list(d)
 print(data.frame(c(list(f,e))))

   X1 X2 X3 X2.71828182845905
 1  ?  ?  ?          2.718282
 2  1  2  3          2.718282

My experience is, that NIO is much faster with small files. But when it comes to large files FileInputStream/FileOutputStream is much faster.

To drop constraint for multiple columns:

declare @table_name nvarchar(256)

declare @Command nvarchar(max) = ''

set @table_name = N'ATableName'

select @Command = @Command + 'ALTER TABLE ' + @table_name + ' drop constraint ' + d.name + CHAR(10)+ CHAR(13)
from sys.tables t
join sys.default_constraints d on d.parent_object_id = t.object_id
join sys.columns c on c.object_id = t.object_id
     and c.column_id = d.parent_column_id
where t.name = @table_name and c.name in ('column1','column2','column3')

--print @Command

execute (@Command)

the safest way is to put the ! for the regex negation within the [[ ]] like this:

if [[ ! ${STR} =~ YOUR_REGEX ]]; then

otherwise it might fail on certain systems.

If you are getting the output Optional(5) when trying to print the value of 5 in an optional Int or String, you should unwrap the value first:

if let value = text {
    print(value)
}

Now you've got the value without the "Optional" string that Swift adds when the value is not unwrapped before.

public static void main(final String[] argv) 
{
    String str;

    str = "hello\r\n\tjava\r\nbook";
    str = str.replaceAll("(\\r|\\n|\\t)", "");
    System.out.println(str);
}

It would be useful to add the tabulation in regex too.

I got similar error sometime back. I had copied the eclipse setup from another laptop to mine. The issue with my setup was that path of the "--launcher.library" in the eclipse.ini file. The path in --launcher.library was that of the old machine and hence I was getting the error

I changed the path of "--launcher.library" in eclipse.ini to the path of eclipse on my laptop and the issue got resolved. I hope this is helpful to someone is getting this error.

This may be just me being really, really picky, but I like to only define constants once. If you use any of the approaches defined above, your action constant will be defines multiple times.

To avoid this, you can do the following:

    public class Url
    {
        public string LocalUrl { get; }

        public Url(string localUrl)
        {
            LocalUrl = localUrl;
        }

        public override string ToString()
        {
            return LocalUrl;
        }
    }

    public abstract class Controller
    {
        public Url RootAction => new Url(GetUrl());

        protected abstract string Root { get; }

        public Url BuildAction(string actionName)
        {
            var localUrl = GetUrl() + "/" + actionName;
            return new Url(localUrl);
        }

        private string GetUrl()
        {
            if (Root == "")
            {
                return "";
            }

            return "/" + Root;
        }

        public override string ToString()
        {
            return GetUrl();
        }
    }

Then create your controllers, say for example the DataController:

    public static readonly DataController Data = new DataController();
    public class DataController : Controller
    {
        public const string DogAction = "dog";
        public const string CatAction = "cat";
        public const string TurtleAction = "turtle";

        protected override string Root => "data";

        public Url Dog => BuildAction(DogAction);
        public Url Cat => BuildAction(CatAction);
        public Url Turtle => BuildAction(TurtleAction);
    }

Then just use it like:

    // GET: Data/Cat
    [ActionName(ControllerRoutes.DataController.CatAction)]
    public ActionResult Etisys()
    {
        return View();
    }

And from your .cshtml (or any code)

<ul>
    <li><a href="@ControllerRoutes.Data.Dog">Dog</a></li>
    <li><a href="@ControllerRoutes.Data.Cat">Cat</a></li>
</ul>

This is definitely a lot more work, but I rest easy knowing compile time validation is on my side.

A gotcha with map::insert() is that it won't replace a value if the key already exists in the map. I've seen C++ code written by Java programmers where they have expected insert() to behave the same way as Map.put() in Java where values are replaced.

This works for me at runtime too:

UltraPictureBox1.Image = My.Resources.MyPicture

No strings involved and if I change the name it is automatically updated by refactoring.

Also instead of adding each file manually, we could do something like:

git add --all

OR

git add -A

This will also remove any files not present or deleted (Tracked files in the current working directory which are now absent).

If you only want to add files which are tracked and have changed, you would want to do

git add -u

What is the difference between git add . & git add --all?

Sounds like a job for set with a custom IFS.

IFS=-
set $STR
var1=$1
var2=$2

(You will want to do this in a function with a local IFS so you don't mess up other parts of your script where you require IFS to be what you expect.)

DELETE from table_name where rowid not in (select min(rowid) FROM table_name group by column_name);

and you can also delete duplicate records in another way

DELETE from table_name a where rowid > (select min(rowid) FROM table_name b where a.column=b.column);

The only way to have multiple, separately accessible functions in a single file is to define STATIC METHODS using object-oriented programming. You'd access the function as myClass.static1(), myClass.static2() etc.

OOP functionality is only officially supported since R2008a, so unless you want to use the old, undocumented OOP syntax, the answer for you is no, as explained by @gnovice.

EDIT

One more way to define multiple functions inside a file that are accessible from the outside is to create a function that returns multiple function handles. In other words, you'd call your defining function as [fun1,fun2,fun3]=defineMyFunctions, after which you could use out1=fun1(inputs) etc.

Try using this:-

mkdir -p dir;

NOTE:- This will also create any intermediate directories that don't exist; for instance,

Check out mkdir -p

or try this:-

if [[ ! -e $dir ]]; then
    mkdir $dir
elif [[ ! -d $dir ]]; then
    echo "$Message" 1>&2
fi

for macbook first i opened terminal then type

open /tmp

or in finder directory you directly enter command+shift+g then type /tmp in go to the folder.

it opens temp folder in finder. then i paste copied csv file into this folder.then again i go to postgres terminal and typed below command and then it is copied my csv data into db table

\copy recharge_operator FROM '/private/tmp/operator.csv' DELIMITER ',' CSV;

I made the following code so that even beginners can understand. Just copy the code and read comments. Note that message to be send is declared as a global variable which you can change just before sending the message. General changes can be done in Handler function.

Dynamic analysis methods

Here I describe a few dynamic analysis methods.

Dynamic methods actually run the program to determine the call graph.

The opposite of dynamic methods are static methods, which try to determine it from the source alone without running the program.

Advantages of dynamic methods:

• catches function pointers and virtual C++ calls. These are present in large numbers in any non-trivial software.

Disadvantages of dynamic methods:

• you have to run the program, which might be slow, or require a setup that you don't have, e.g. cross-compilation
• only functions that were actually called will show. E.g., some functions could be called or not depending on the command line arguments.

KcacheGrind

https://kcachegrind.github.io/html/Home.html

Test program:

int f2(int i) { return i + 2; }
int f1(int i) { return f2(2) + i + 1; }
int f0(int i) { return f1(1) + f2(2); }
int pointed(int i) { return i; }
int not_called(int i) { return 0; }

int main(int argc, char **argv) {
    int (*f)(int);
    f0(1);
    f1(1);
    f = pointed;
    if (argc == 1)
        f(1);
    if (argc == 2)
        not_called(1);
    return 0;
}

Usage:

sudo apt-get install -y kcachegrind valgrind

# Compile the program as usual, no special flags.
gcc -ggdb3 -O0 -o main -std=c99 main.c

# Generate a callgrind.out.<PID> file.
valgrind --tool=callgrind ./main

# Open a GUI tool to visualize callgrind data.
kcachegrind callgrind.out.1234

You are now left inside an awesome GUI program that contains a lot of interesting performance data.

On the bottom right, select the "Call graph" tab. This shows an interactive call graph that correlates to performance metrics in other windows as you click the functions.

To export the graph, right click it and select "Export Graph". The exported PNG looks like this:

From that we can see that:

• the root node is _start, which is the actual ELF entry point, and contains glibc initialization boilerplate
• f0, f1 and f2 are called as expected from one another
• pointed is also shown, even though we called it with a function pointer. It might not have been called if we had passed a command line argument.
• not_called is not shown because it didn't get called in the run, because we didn't pass an extra command line argument.

The cool thing about valgrind is that it does not require any special compilation options.

Therefore, you could use it even if you don't have the source code, only the executable.

valgrind manages to do that by running your code through a lightweight "virtual machine". This also makes execution extremely slow compared to native execution.

As can be seen on the graph, timing information about each function call is also obtained, and this can be used to profile the program, which is likely the original use case of this setup, not just to see call graphs: How can I profile C++ code running on Linux?

Tested on Ubuntu 18.04.

gcc -finstrument-functions + etrace

https://github.com/elcritch/etrace

-finstrument-functions adds callbacks, etrace parses the ELF file and implements all callbacks.

I couldn't get it working however unfortunately: Why doesn't `-finstrument-functions` work for me?

Claimed output is of format:

\-- main
|   \-- Crumble_make_apple_crumble
|   |   \-- Crumble_buy_stuff
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   \-- Crumble_prepare_apples
|   |   |   \-- Crumble_skin_and_dice
|   |   \-- Crumble_mix
|   |   \-- Crumble_finalize
|   |   |   \-- Crumble_put
|   |   |   \-- Crumble_put
|   |   \-- Crumble_cook
|   |   |   \-- Crumble_put
|   |   |   \-- Crumble_bake

Likely the most efficient method besides specific hardware tracing support, but has the downside that you have to recompile the code.

A lot of people seem to be looking for this answer. I found it buried in an answer to another question here: Syncing column width of between tables in two different frames, etc

Of the dozens of methods I have tried this is the only method I found that works reliably to allow you to have a scrolling bottom table with the header table having the same widths.

Here is how I did it, first I improved upon the jsfiddle above to create this function, which works on both td and th (in case that trips up others who use th for styling of their header rows).

var setHeaderTableWidth= function (headertableid,basetableid) {
            $("#"+headertableid).width($("#"+basetableid).width());
            $("#"+headertableid+" tr th").each(function (i) {
                $(this).width($($("#"+basetableid+" tr:first td")[i]).width());
            });
            $("#" + headertableid + " tr td").each(function (i) {
                $(this).width($($("#" + basetableid + " tr:first td")[i]).width());
            });
        }

Next, you need to create two tables, NOTE the header table should have an extra TD to leave room in the top table for the scrollbar, like this:

 <table id="headertable1" class="input-cells table-striped">
        <thead>
            <tr style="background-color:darkgray;color:white;"><th>header1</th><th>header2</th><th>header3</th><th>header4</th><th>header5</th><th>header6</th><th></th></tr>
        </thead>
     </table>
    <div id="resizeToBottom" style="overflow-y:scroll;overflow-x:hidden;">
        <table id="basetable1" class="input-cells table-striped">
            <tbody >
                <tr>
                    <td>testdata</td>
                    <td>2</td>
                    <td>3</td>
                    <td>4</span></td>
                    <td>55555555555555</td>
                    <td>test</td></tr>
            </tbody>
        </table>
    </div>

Then do something like:

        setHeaderTableWidth('headertable1', 'basetable1');
        $(window).resize(function () {
            setHeaderTableWidth('headertable1', 'basetable1');
        });

This is the only solution that I found on Stack Overflow that works out of many similar questions that have been posted, that works in all my cases.

For example, I tried the jQuery stickytables plugin which does not work with durandal, and the Google Code project here https://code.google.com/p/js-scroll-table-header/issues/detail?id=2

Other solutions involving cloning the tables, have poor performance, or suck and don't work in all cases.

There is no need for these overly complex solutions. Just make two tables like the examples below and call setHeaderTableWidth function like described here and boom, you are done.

If this does not work for you, you probably were playing with your CSS box-sizing property and you need to set it correctly. It is easy to screw up your CSS content by accident. There are many things that can go wrong, so just be aware/careful of that. This approach works for me.

webView.setDownloadListener(new DownloadListener()
        {
            @Override
            public void onDownloadStart(String url, String userAgent,
                                        String contentDisposition, String mimeType,
                                        long contentLength) {
                DownloadManager.Request request = new DownloadManager.Request(
                        Uri.parse(url));
                request.setMimeType(mimeType);
                String cookies = CookieManager.getInstance().getCookie(url);
                request.addRequestHeader("cookie", cookies);
                request.addRequestHeader("User-Agent", userAgent);
                request.setDescription("Downloading File...");
                request.setTitle(URLUtil.guessFileName(url, contentDisposition, mimeType));
                request.allowScanningByMediaScanner();
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                request.setDestinationInExternalPublicDir(
                        Environment.DIRECTORY_DOWNLOADS, URLUtil.guessFileName(
                                url, contentDisposition, mimeType));
                DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
                dm.enqueue(request);
                Toast.makeText(getApplicationContext(), "Downloading File", Toast.LENGTH_LONG).show();
            }});

With reference to SJG's answer and from W3Schools.com

As of jQuery version 1.7, the off() method is the new replacement for the unbind(), die() and undelegate() methods. This method brings a lot of consistency to the API, and we recommend that you use this method, as it simplifies the jQuery code base.

This gives:

$("#someid").off("click").live("click",function(){...

or

$("#someid").off("click").bind("click",function(){...

I have written a simple component using jQuery and bootstrap. Give it a try: https://github.com/mahpour/bootstrap-input-clear-button

I had a similar issue, because of my replication binary logs.

If this is the case, just create a cronjob to run this query every day:

PURGE BINARY LOGS BEFORE DATE_SUB( NOW(), INTERVAL 2 DAY );

This will remove all binary logs older than 2 days.

I found this solution here.

Consider the partial map.cshtml at Partials/Map.cshtml. This can be called from the Page where the partial is to be rendered, simply by using the <partial> tag:

<partial name="Partials/Map" model="new Pages.Partials.MapModel()" />

This is one of the easiest methods I encountered (although I am using razor pages, I am sure same is for MVC too)

I had this error, I follwed below three steps to solve,

1). check proxy settings in settings.xml refer,

2). .m2 diretory to release cached files causing problems

3) Point your eclipse to correct JDK installation. Refer No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? to know how

You should put it in the <head>. I typically put style references above JS and I order my JS from top to bottom if some of them are dependent on others, but I beleive all of the references are loaded before the page is rendered.

Go with a triple negative:

If (Not Not FileNamesList) <> 0 Then
    ' Array has been initialized, so you're good to go.
Else
    ' Array has NOT been initialized
End If

Or just:

If (Not FileNamesList) = -1 Then
    ' Array has NOT been initialized
Else
    ' Array has been initialized, so you're good to go.
End If

In VB, for whatever reason, Not myArray returns the SafeArray pointer. For uninitialized arrays, this returns -1. You can Not this to XOR it with -1, thus returning zero, if you prefer.

               (Not myArray)   (Not Not myArray)
Uninitialized       -1                 0
Initialized    -someBigNumber   someOtherBigNumber

A CASE statement is an expression, just like a boolean comparison. That means the 'AND' needs to go before the 'CASE' statement, not within it.:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)

AND -- Added the "AND" here

CASE WHEN @day = 'Monday' THEN (Monday = 1)   -- Removed "AND" 
    WHEN @day = 'Tuesday' THEN (Tuesday = 1)  -- Removed "AND" 
    ELSE AND (Wednesday = 1) 
END

Let's say I have an array arr. When would the following not give the number of elements of the array: sizeof(arr) / sizeof(arr[0])?

One thing I've often seen new programmers doing this:

void f(Sample *arr)
{
   int count = sizeof(arr)/sizeof(arr[0]); //what would be count? 10?
}

Sample arr[10];
f(arr);

So new programmers think the value of count will be 10. But that's wrong.

Even this is wrong:

void g(Sample arr[]) //even more deceptive form!
{
   int count = sizeof(arr)/sizeof(arr[0]); //count would not be 10  
}

It's all because once you pass an array to any of these functions, it becomes pointer type, and so sizeof(arr) would give the size of pointer, not array!

EDIT:

The following is an elegant way you can pass an array to a function, without letting it to decay into pointer type:

template<size_t N>
void h(Sample (&arr)[N])
{
    size_t count = N; //N is 10, so would be count!
    //you can even do this now:
    //size_t count = sizeof(arr)/sizeof(arr[0]);  it'll return 10!
}
Sample arr[10];
h(arr); //pass : same as before!

I search the string (starting rightmost) for the first character in the range 1 to 9 (ASCII value 49-57) then null (set to 0) each char right of it - see below:

void stripTrailingZeros(void) { 
    //This finds the index of the rightmost ASCII char[1-9] in array
    //All elements to the left of this are nulled (=0)
    int i = 20;
    unsigned char char1 = 0; //initialised to ensure entry to condition below

    while ((char1 > 57) || (char1 < 49)) {
        i--;
        char1 = sprintfBuffer[i];
    }

    //null chars left of i
    for (int j = i; j < 20; j++) {
        sprintfBuffer[i] = 0;
    }
}

Look at /Applications/MAMP/htdocs/testygubbins/OO/test/header.php line 15.

At that position, it makes some output. Fix it. :)

As an alternative way to floating:

<style>
    .wrapper{position:relative;}
    .right,.left{width:50%; position:absolute;}
    .right{right:0;}
    .left{left:0;}
</style>
...
<div class="wrapper">
    <div class="left"></div>
    <div class="right"></div>
</div>

Considering that there's no necessity to position the .left div as absolute (depending on your direction, this could be the .right one) due to that would be in the desired position in natural flow of html code.

It's a CRLF problem. I fixed the problem using this:

git config --global core.eol lf

git config --global core.autocrlf input

find . -type f -print0 | xargs -0 dos2unix

Follow these steps

1>Download the *.jar file from here .

2>Put the *.jar file into the folder eclipse/dropins/ and Restart eclipse.

3>In the top right of eclipse, click the DDMS icon.

4>Select the proper emulator in the left panel.

5In the File Explorer tab on the main panel, go to /data/data/[YOUR.APP.NAMESPACE]/databases.

6>Underneath the DDMS icon, there should be a new blue icon of a Database light up when you select your database. Click it and you will see a Questoid Sqlite Manager tab open up to view your data.

*Note: If the database doesn't light up, it may be because your database doesn't have a *.db file extension. Be sure your database is called [DATABASE_NAME].db

*Note: if you want to use a DB without .db-Extension:

-Download this Questoid SqLiteBrowser: Download fro here.

-Unzip and put it into eclipse/dropins (not Plugins).

-Check this for more information Click here.

The first case will fail when JS is off. It's also a little bit slower since JS must be parsed first (DOM must be loaded). However JS is safer since the destination doesn't know the referer and your redirect might be tracked (referers aren't reliable in general yet this is something).

You can also use meta refresh tag. It also requires DOM to be loaded.

Since str_split() function is not multibyte safe, an easy solution to split UTF-8 encoded string is to use preg_split() with u (PCRE_UTF8) modifier.

preg_split( '//u', $str, null, PREG_SPLIT_NO_EMPTY )

A short solution is this (PHP 5.3+):

$output['alternate_title'] = $output['alternate_title'] ?:'';

You get either the value of the variable, if it doesn't evaluate to false, or the false expression. (The one after the ':')

Using the ternary Operator, without the "if true" parameter, will return the result of the test expression (The first one ) Since undefined evaluates to false, the false expression will be returned.

In PHP 7 there is the slightly more elegant Null coalescing operator:

$output['alternate_title'] = $output['alternate_title'] ?? '';

(It would be nice with a default assignment operator like '?=')

man bzero

NAME
   bzero - write zero-valued bytes

SYNOPSIS
   #include <strings.h>

   void bzero(void *s, size_t n);

DESCRIPTION
   The  bzero()  function sets the first n bytes of the byte area starting
   at s to zero (bytes containing '\0').

I added a ticket to add an option of some sort here:

https://github.com/pydata/pandas/issues/1450

In the meantime, result.fillna('') should do what you want

EDIT: in the development version (to be 0.8.0 final) if you specify an empty list of na_values, empty strings will stay empty strings in the result

When setting http_proxy and https_proxy, you are also probably going to need no_proxy for URLs on the same side of the proxy. https://msdn.microsoft.com/en-us/library/hh272656(v=vs.120).aspx

As I understand it, "request timeout" means the ICMP packet reached from one host to the other host but the reply could not reach the requesting host. There may be more packet loss or some physical issue. "destination host unreachable" means there is no proper route defined between two hosts.

You can use the DataFrame head and tail methods as syntactic sugar instead of slicing/loc here. I use a split size of 3; for your example use headSize=10

def split(df, headSize) :
    hd = df.head(headSize)
    tl = df.tail(len(df)-headSize)
    return hd, tl

df = pd.DataFrame({    'A':[2,4,6,8,10,2,4,6,8,10],
                       'B':[10,-10,0,20,-10,10,-10,0,20,-10],
                       'C':[4,12,8,0,0,4,12,8,0,0],
                      'D':[9,10,0,1,3,np.nan,np.nan,np.nan,np.nan,np.nan]})

# Split dataframe into top 3 rows (first) and the rest (second)
first, second = split(df, 3)

Whether you're using the maven eclipse plugin or m2eclipse, Eclipse's project configuration is derived from the POM, so you need to configure the maven compiler plugin for 1.6 (it defaults to 1.4).

Add the following to your project's pom.xml, save, then go to your Eclipse project and select Properties > Maven > Update Project Configuration:

<project>
 <build>
  <pluginManagement>
   <plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>          
        <configuration>
            <source>1.6</source>
            <target>1.6</target>
        </configuration>
    </plugin>
   </plugins>
  </pluginManagement>
 </build>
</project>

Try adding this class

class="pager"

<p class="pager" style="line-height: 70px;">
    <button type="submit" class="btn">Confirm</button>
</p>

I tried mine within a <div class=pager><button etc etc></div> which worked well

See http://getbootstrap.com/components/ look under Pagination -> Pager

This looks like the correct bootstrap class to center this, text-align: center; is meant for text not images and blocks etc.

VERY IMPORTANT Additional info on difference between .text() and .html():

If your selector selects more than one item, e.g you have two spans like so <span class="foo">bar1</span> <span class="foo">bar2</span> ,

then

$('.foo').text(); appends the two texts and give you that; whereas

$('.foo').html(); gives you only one of those.

You can use Newtonsoft.Json just add Newtonsoft.dll to your project and use below script

using System;
using Newtonsoft.Json;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{

    [Serializable]
    public class Person
    {
        public string id;
        public string name;
    }
    public Person[] person;

    private void Start()
    {
       var myjson = JsonConvert.SerializeObject(person);

        print(myjson);

    }
}

another solution is using JsonHelper

using System;
using Newtonsoft.Json;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{

    [Serializable]
    public class Person
    {
        public string id;
        public string name;
    }
    public Person[] person;

    private void Start()
    {
        var myjson = JsonHelper.ToJson(person);

        print(myjson);

    }
}

My solution:

Object.prototype.__index=function(index)
                         {var i=-1;
                          for (var key in this)
                              {if (this.hasOwnProperty(key) && typeof(this[key])!=='function')
                                  {++i;
                                  }
                               if (i>=index)
                                  {return this[key];
                                  }
                              }

Code snippet underneath!

Please take a look at these documentations and examples at MDN, and you will find your answer. This is the propper way to do it I would say.

Creating and triggering events

Dispatch Event (example)

Taken from the 'Dispatch Event (example)'-HTML-link (simulate click):

function simulateClick() {

  var evt = document.createEvent("MouseEvents");

  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);

  var cb = document.getElementById("checkbox"); 
  var canceled = !cb.dispatchEvent(evt);

  if(canceled) {
    // A handler called preventDefault
    alert("canceled");
  } else {
    // None of the handlers called preventDefault
    alert("not canceled");
  }
}

This is how I would do it (2017 ..) :

Simply using MouseEvent.

function simulateClick() {

    var evt = new MouseEvent("click");

    var cb = document.getElementById("checkbox");
    var canceled = !cb.dispatchEvent(evt);

    if (canceled) {
        // A handler called preventDefault
        console.log("canceled");
    } else {
        // None of the handlers called preventDefault
        console.log("not canceled");
    }
}

document.getElementById("button").onclick = evt => {_x000D_
    _x000D_
    simulateClick()_x000D_
}_x000D_
_x000D_
function simulateClick() {_x000D_
_x000D_
    var evt = new MouseEvent("click");_x000D_
_x000D_
    var cb = document.getElementById("checkbox");_x000D_
    var canceled = !cb.dispatchEvent(evt);_x000D_
_x000D_
    if (canceled) {_x000D_
        // A handler called preventDefault_x000D_
        console.log("canceled");_x000D_
    } else {_x000D_
        // None of the handlers called preventDefault_x000D_
        console.log("not canceled");_x000D_
    }_x000D_
}

<input type="checkbox" id="checkbox">_x000D_
<br>_x000D_
<br>_x000D_
<button id="button">Check it out, or not</button>

select * from 
(select 
ROW_NUMBER() OVER(PARTITION BY tblFruit_FruitType ORDER BY tblFruit_FruitType DESC) as tt
,*
from tblFruit
) a
where a.tt=1

A more modern way is to use flexbox:

ul{_x000D_
  list-style-type:none;_x000D_
  display:flex;_x000D_
  justify-content: center;_x000D_
_x000D_
}_x000D_
ul li{_x000D_
  display: list-item;_x000D_
  background: black;_x000D_
  padding: 5px 10px;_x000D_
  color:white;_x000D_
  margin: 0 3px;_x000D_
}_x000D_
div{_x000D_
  background: wheat;_x000D_
}

<div>_x000D_
<ul>_x000D_
  <li>One</li>_x000D_
  <li>Two</li>_x000D_
  <li>Three</li>_x000D_
</ul>  _x000D_
_x000D_
</div>

You can try this it has worked for me.

That is because you are trying to access the plugin before it's loaded. You should try making a call to it when the DOM is loaded by surrounding it with this:

$(document).ready(function(){
    $("#colorpicker").colorpicker();
}

Combining several of the answers here together, the most useful solution seems to be:

find . -maxdepth 1 -type d -print0 |
xargs -0 -I {} sh -c 'echo -e $(find "{}" -printf "\n" | wc -l) "{}"' |
sort -n

It can handle odd things like file names that include spaces parenthesis and even new lines. It also sorts the output by the number of files.

You can increase the number after -maxdepth to get sub directories counted too. Keep in mind that this can potentially take a long time, particularly if you have a highly nested directory structure in combination with a high -maxdepth number.

You could use the existing methods from the Character class. Take a look at the docs:

http://download.java.net/jdk7/archive/b123/docs/api/java/lang/Character.html#isDigit(char)

So, you could do something like this...

String character = in.next();
char c = character.charAt(0);
...
if (Character.isDigit(c)) { 
    ... 
} else if (Character.isLetter(c)) {
    ...
}
...

If you ever want to know exactly how this is implemented, you could always look at the Java source code.

I want to add this answer for quickreference. Feel free to update.

.NET Regex using balancing groups.

\((?>\((?<c>)|[^()]+|\)(?<-c>))*(?(c)(?!))\)

Where c is used as the depth counter.

Demo at Regexstorm.com

• Stack Overflow: Using RegEx to balance match parenthesis
• Wes' Puzzling Blog: Matching Balanced Constructs with .NET Regular Expressions
• Greg Reinacker's Weblog: Nested Constructs in Regular Expressions

PCRE using a recursive pattern.

\((?:[^)(]+|(?R))*+\)

Demo at regex101; Or without alternation:

\((?:[^)(]*(?R)?)*+\)

Demo at regex101; Or unrolled for performance:

\([^)(]*+(?:(?R)[^)(]*)*+\)

Demo at regex101; The pattern is pasted at (?R) which represents (?0).

Perl, PHP, Notepad++, R: perl=TRUE, Python: Regex package with (?V1) for Perl behaviour.

Ruby using subexpression calls.

With Ruby 2.0 \g<0> can be used to call full pattern.

\((?>[^)(]+|\g<0>)*\)

Demo at Rubular; Ruby 1.9 only supports capturing group recursion:

(\((?>[^)(]+|\g<1>)*\))

Demo at Rubular  (atomic grouping since Ruby 1.9.3)

JavaScript  API :: XRegExp.matchRecursive

XRegExp.matchRecursive(str, '\\(', '\\)', 'g');

JS, Java and other regex flavors without recursion up to 2 levels of nesting:

\((?:[^)(]+|\((?:[^)(]+|\([^)(]*\))*\))*\)

Demo at regex101. Deeper nesting needs to be added to pattern.
To fail faster on unbalanced parenthesis drop the + quantifier.

Java: An interesting idea using forward references by @jaytea.

_{Reference - What does this regex mean?}

• rexegg.com - Recursive Regular Expressions
• Regular-Expressions.info - Regular Expression Recursion

James Gosling likened designing Java to the following:

"There's this principle about moving, when you move from one apartment to another apartment. An interesting experiment is to pack up your apartment and put everything in boxes, then move into the next apartment and not unpack anything until you need it. So you're making your first meal, and you're pulling something out of a box. Then after a month or so you've used that to pretty much figure out what things in your life you actually need, and then you take the rest of the stuff -- forget how much you like it or how cool it is -- and you just throw it away. It's amazing how that simplifies your life, and you can use that principle in all kinds of design issues: not do things just because they're cool or just because they're interesting."

You can read the context of the quote here

Basically operator overloading is great for a class that models some kind of point, currency or complex number. But after that you start running out of examples fast.

Another factor was the abuse of the feature in C++ by developers overloading operators like '&&', '||', the cast operators and of course 'new'. The complexity resulting from combining this with pass by value and exceptions is well covered in the Exceptional C++ book.

Don't declare the variable in the userform. Declare it as Public in the module.

Public pass As String

In the Userform

Private Sub CommandButton1_Click()
    pass = UserForm1.TextBox1
    Unload UserForm1
End Sub

In the Module

Public pass As String

Public Sub Login()
    '
    '~~> Rest of the code
    '
    UserForm1.Show
    driver.findElementByName("PASSWORD").SendKeys pass
    '
    '~~> Rest of the code
    '
End Sub

You might want to also add an additional check just before calling the driver.find... line?

If Len(Trim(pass)) <> 0 Then

This will ensure that a blank string is not passed.

In java <T> means Generic class. A Generic Class is a class which can work on any type of data type or in other words we can say it is data type independent.

public class Shape<T> {
    // T stands for "Type"
    private T t;

    public void set(T t) { this.t = t; }
    public T get() { return t; }
}

Where T means type. Now when you create instance of this Shape class you will need to tell the compiler for what data type this will be working on.

Example:

Shape<Integer> s1 = new Shape();
Shape<String> s2 = new Shape();

Integer is a type and String is also a type.

<T> specifically stands for generic type. According to Java Docs - A generic type is a generic class or interface that is parameterized over types.

First take array of promises(promise array) and after resolve these promise array using Promise.all(promisearray).

var arry=['raju','ram','abdul','kruthika'];

var promiseArry=[];
for(var i=0;i<arry.length;i++) {
  promiseArry.push(dbFechFun(arry[i]));
}

Promise.all(promiseArry)
  .then((result) => {
    console.log(result);
  })
  .catch((error) => {
     console.log(error);
  });

function dbFetchFun(name) {
  // we need to return a  promise
  return db.find({name:name}); // any db operation we can write hear
}

Try adding these params to your docker yml file

restart: "no"
  restart: always
  restart: on-failure
  restart: unless-stopped
  environment:
    POSTGRES_DB: "db_name"
    POSTGRES_HOST_AUTH_METHOD: "trust"

Final file should look something like this

postgres:
  restart: "no"
  restart: always
  restart: on-failure
  restart: unless-stopped
  image: postgres:latest
  volumes:
    - /data/postgresql:/var/lib/postgresql
  ports:
    - "5432:5432"
  environment:
    POSTGRES_DB: "db_name"
    POSTGRES_HOST_AUTH_METHOD: "trust"

As suggested here you can also inject the HttpServletRequest as a method param, e.g.:

public MyResponseObject myApiMethod(HttpServletRequest request, ...) {
    ...
}

From MSDN
$0 - "Substitutes the last substring matched by group number number (decimal)."

In .NET Regular expressions group 0 is always the entire match. For a literal $ you need to

string value = Regex.Replace("%PolicyAmount%", "%PolicyAmount%", @"$$0", RegexOptions.IgnoreCase);

alter table table_name 
rename column old_column_name/field_name to new_column_name/field_name;

example: alter table student column name to username;

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not dict
>>>

You can attempt to use the PHP header function to do the redirect. You will want to set the output buffer so your browser doesn't throw a redirect warning to the screen.

ob_start();
header("Location: " . $website);
ob_end_flush();

It's just the method. You're not missing anything. The official documentation shows that you can use list unpacking to supply several paths:

s = "c:/,home,foo,bar,some.txt".split(",")
os.path.join(*s)

Note the *s intead of just s in os.path.join(*s). Using the asterisk will trigger the unpacking of the list, which means that each list argument will be supplied to the function as a separate argument.

I suggest an approach that does not require Typescript 2.1:

class Person {
    public name: string;
    public address?: string;
    public age: number;

    public constructor(init:Person) {
        Object.assign(this, init);
    }

    public someFunc() {
        // todo
    }
}

let person = new Person(<Person>{ age:20, name:"John" });
person.someFunc();

key points:

• Typescript 2.1 not required, Partial<T> not required
• It supports functions (in comparison with simple type assertion which does not support functions)

the easiest way is to change version in every pom.xml to arbitrary version. then check that dependency management to use the correct version of the module used in this module! for example, if u want increase versioning for a tow module project u must do like flowing:

in childe module :

    <parent>
       <artifactId>A-application</artifactId>
       <groupId>com.A</groupId>
       <version>new-version</version>
    </parent>

and in parent module :

<groupId>com.A</groupId>
<artifactId>A-application</artifactId>
<version>new-version</version>

This program will prints all the classes with its physical path. use can simply copy this to any JSP if you need to analyse the class loading from any web/application server.

import java.lang.reflect.Field;
import java.util.Vector;

public class TestMain {

    public static void main(String[] args) {
        Field f;
        try {
            f = ClassLoader.class.getDeclaredField("classes");
            f.setAccessible(true);
            ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
            Vector<Class> classes =  (Vector<Class>) f.get(classLoader);

            for(Class cls : classes){
                java.net.URL location = cls.getResource('/' + cls.getName().replace('.',
                '/') + ".class");
                System.out.println("<p>"+location +"<p/>");
            }
        } catch (Exception e) {

            e.printStackTrace();
        }
    }
}

While adding 'DirectoryIndex index.php' to a .htaccess file may work,

NOTE:

In general, you should never use .htaccess files

This is quoted from http://httpd.apache.org/docs/1.3/howto/htaccess.html
Although this refers to an older version of apache, I believe the principle still applies.

Adding the following to your httpd.conf (if you have access to it) is considered better form, causes less server overhead and has the exact same effect:

<Directory /myapp>
DirectoryIndex index.php
</Directory>

If error comes for ".settings/language.settings.xml" or any such file you don't need to git.

1. Team -> Commit -> Staged filelist, check if unwanted file exists, -> Right click on each-> remove from index.
2. From UnStaged filelist, check if unwanted file exists, -> Right click on each-> Ignore.

Now if Staged file list empty, and Unstaged file list all files are marked as Ignored. You can pull. Otherwise, follow other answers.

I found the following slightly altered range useful for parsing comment blocks out of a database, this means that you won't have to contend with tab and escape characters which would cause a CSV field to become upset.

parsememo = Regex.Replace(parsememo, @"[^\u001F-\u007F]", string.Empty);

If you want to avoid other special characters or particular punctuation check the ascii table

You had a unescaped " in the onclick handler, escape it with \"

$('#contentData').append("<div class='media'><div class='media-body'><h4 class='media-heading'>" + v.Name + "</h4><p>" + v.Description + "</p><a class='btn' href='" + type + "'  onclick=\"(canLaunch('" + v.LibraryItemId + " '))\">View &raquo;</a></div></div>")

var visibilityChange = (function (window) {
    var inView = false;
    return function (fn) {
        window.onfocus = window.onblur = window.onpageshow = window.onpagehide = function (e) {
            if ({focus:1, pageshow:1}[e.type]) {
                if (inView) return;
                fn("visible");
                inView = true;
            } else if (inView) {
                fn("hidden");
                inView = false;
            }
        };
    };
}(this));

visibilityChange(function (state) {
    console.log(state);
});

You should use Adaptive hashing like http://en.wikipedia.org/wiki/Bcrypt for securing passwords

Sorry this is and old thread but some people would still need this I guess,

Note: I achieved this using Animate.css library for animating the fade.

I used your code and just added .hidden class (using bootstrap's hidden class) but you can still just define .hidden { opacity: 0; }

$(document).ready(function() {

/* Every time the window is scrolled ... */

$(window).scroll( function(){

/* Check the location of each desired element */
$('.hideme').each( function(i){

    var bottom_of_object = $(this).position().top + $(this).outerHeight();
    var bottom_of_window = $(window).scrollTop() + $(window).height();


    /* If the object is completely visible in the window, fade it it */
    if( bottom_of_window > bottom_of_object ){

        $(this).removeClass('hidden');
        $(this).addClass('animated fadeInUp');
    }    else {
            $(this).addClass('hidden');
               }

}); 
}); 
});

Another Note: Applying this to containers might cause it to be glitchy.

If you are willing to use an external library, I can't recommend bstrlib enough. It takes a little extra setup, but is easier to use in the long run.

For example, split the string below, one first creates a bstring with the bfromcstr() call. (A bstring is a wrapper around a char buffer). Next, split the string on commas, saving the result in a struct bstrList, which has fields qty and an array entry, which is an array of bstrings.

bstrlib has many other functions to operate on bstrings

Easy as pie...

#include "bstrlib.h"
#include <stdio.h>
int main() {
  int i;
  char *tmp = "Hello,World,sak";
  bstring bstr = bfromcstr(tmp);
  struct bstrList *blist = bsplit(bstr, ',');
  printf("num %d\n", blist->qty);
  for(i=0;i<blist->qty;i++) {
    printf("%d: %s\n", i, bstr2cstr(blist->entry[i], '_'));
  }

}

string html = File.ReadAllText(path);

In your parseResponse() you are creating a new instance of the BusinessAdapter class, but you aren't actually using it anywhere, so your RecyclerView doesn't know the new instance exists.

You either need to:

• Call recyclerView.setAdapter(mBusinessAdapter) again to update the RecyclerView's adapter reference to point to your new one
• Or just remove mBusinessAdapter = new BusinessAdapter(mBusinesses); to continue using the existing adapter. Since you haven't changed the mBusinesses reference, the adapter will still use that array list and should update correctly when you call notifyDataSetChanged().

You can use .concat method to create copy of your array with new data:

this.setState({ myArray: this.state.myArray.concat('new value') })

But beware of special behaviour of .concat method when passing arrays - [1, 2].concat(['foo', 3], 'bar') will result in [1, 2, 'foo', 3, 'bar'].

For SSMS 18 (specifically 18.6), I found my backup here C:\Windows\SysWOW64\Visual Studio 2017\Backup Files\Solution1.

Kudos to Matthew Lock for giving me the idea to just search across my whole machine!

You can use the .forEach() method of JavaScript for looping through JSON.

var datesBooking = [_x000D_
    {"date": "04\/24\/2018"},_x000D_
      {"date": "04\/25\/2018"}_x000D_
    ];_x000D_
    _x000D_
    datesBooking.forEach(function(data, index) {_x000D_
      console.log(data);_x000D_
    });

Also, make sure you startup project is the project that contains your dbcontext (or relevant app.config). Mine was trying to start up a website project which didnt have all the necessary configuration settings.

newTitle is a local variable where you create the fields. So when that functions ends, the variable newTitle, does not exist anymore. (The JTextField that was referenced by newTitle does still exist however.)

Thus, increase the scope of the variable, so that you can access it another method.

public SomeFrame extends JFrame {
   JTextField myTitle;//can be used anywhere in this class

   creationOfTheFields()
   {
   //other code
      myTitle = new JTextField("spam");  
      myTitle.setBounds(80, 40, 225, 20);
      options.add(myTitle);
   //blabla other code
   }

   private void New_Name()  
   {  
      this.setTitle(myTitle.getText());  
   } 
}

Following steps solves my problem: Add "C:\Windows\System32\" to your system path variables Run npm eject, Run npm start, Run npm eject, and agian run npm start And it worked

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

i encountered this error in quite a stupid way

@Autowired

what happened is that I commented a line for some reason and left the annotation which made spring think that the method needs to be autowired

I'm having a problem with your script in Firefox. When I scroll down, the script continues to add a margin to the page and I never reach the bottom of the page. This occurs because the ActionBox is still part of the page elements. I posted a demo here.

• One solution would be to add a position: fixed to the CSS definition, but I see this won't work for you
• Another solution would be to position the ActionBox absolutely (to the document body) and adjust the top.
• Updated the code to fit with the solution found for others to benefit.

UPDATED:

CSS

#ActionBox {
 position: relative;
 float: right;
}

Script

var alert_top = 0;
var alert_margin_top = 0;

$(function() {
  alert_top = $("#ActionBox").offset().top;
  alert_margin_top = parseInt($("#ActionBox").css("margin-top"),10);

  $(window).scroll(function () {
    var scroll_top = $(window).scrollTop();
    if (scroll_top > alert_top) {
      $("#ActionBox").css("margin-top", ((scroll_top-alert_top)+(alert_margin_top*2)) + "px");
      console.log("Setting margin-top to " + $("#ActionBox").css("margin-top"));
    } else {
      $("#ActionBox").css("margin-top", alert_margin_top+"px");
    };
  });
});

Also it is important to add a base (10 in this case) to your parseInt(), e.g.

parseInt($("#ActionBox").css("top"),10);

If I want to create JavaScript Object from string generated by for loop then I would JSON to Object approach. I would generate JSON string by iterating for loop and then use any popular JavaScript Framework to evaluate JSON to Object.

I have used Prototype JavaScript Framework. I have two array with keys and values. I iterate through for loop and generate valid JSON string. I use evalJSON() function to convert JSON string to JavaScript object.

Here is example code. Tryout on your FireBug Console

var key = ["color", "size", "fabric"];
var value = ["Black", "XL", "Cotton"];

var json = "{ ";
for(var i = 0; i < key.length; i++) {
    (i + 1) == key.length ? json += "\"" + key[i] + "\" : \"" + value[i] + "\"" : json += "\"" + key[i] + "\" : \"" + value[i] + "\",";
}
json += " }";
var obj = json.evalJSON(true);
console.log(obj);

I found the following command to run from command line:

vlc.exe --extraintf=http:logger --verbose=2 --file-logging --logfile=vlc-log.txt

I created this simple one a while back. The main challenge I had was to create a good build environment - a makefile that would compile and link/deploy everything without having to use the GUI. For the code, here is the header:

class AMLed
{
    private:
          uint8_t _ledPin;
          long _turnOffTime;

    public:
          AMLed(uint8_t pin);
          void setOn();
          void setOff();
          // Turn the led on for a given amount of time (relies
          // on a call to check() in the main loop()).
          void setOnForTime(int millis);
          void check();
};

And here is the main source

AMLed::AMLed(uint8_t ledPin) : _ledPin(ledPin), _turnOffTime(0)
{
    pinMode(_ledPin, OUTPUT);
}

void AMLed::setOn()
{
    digitalWrite(_ledPin, HIGH);
}

void AMLed::setOff()
{
    digitalWrite(_ledPin, LOW);
}

void AMLed::setOnForTime(int p_millis)
{
    _turnOffTime = millis() + p_millis;
    setOn();
}

void AMLed::check()
{
    if (_turnOffTime != 0 && (millis() > _turnOffTime))
    {
        _turnOffTime = 0;
        setOff();
    }
}

It's more prettily formatted here: http://amkimian.blogspot.com/2009/07/trivial-led-class.html

To use, I simply do something like this in the .pde file:

#include "AM_Led.h"

#define TIME_LED    12   // The port for the LED

AMLed test(TIME_LED);

There are tons of sample code online as to how to do this.

Here is just one example of how to do this: http://geekswithblogs.net/dotNETvinz/archive/2009/04/30/creating-a-simple-registration-form-in-asp.net.aspx

you define the text boxes between the following tag:

<form id="form1" runat="server"> 

you create your textboxes and define them to runat="server" like so:

<asp:TextBox ID="TxtName" runat="server"></asp:TextBox>

define a button to process your logic like so (notice the onclick):

<asp:Button ID="Button1" runat="server" Text="Save" onclick="Button1_Click" />

in the code behind, you define what you want the server to do if the user clicks on the button by defining a method named

protected void Button1_Click(object sender, EventArgs e)

or you could just double click the button in the design view.

Here is a very quick sample of code to insert into a table in the button click event (codebehind)

protected void Button1_Click(object sender, EventArgs e)
{
   string name = TxtName.Text; // Scrub user data

   string connString = ConfigurationManager.ConnectionStrings["yourconnstringInWebConfig"].ConnectionString;
   SqlConnection conn = null;
   try
   {
          conn = new SqlConnection(connString);
          conn.Open();

          using(SqlCommand cmd = new SqlCommand())
          {
                 cmd.Conn = conn;
                 cmd.CommandType = CommandType.Text;
                 cmd.CommandText = "INSERT INTO dummyTable(name) Values (@var)";
                 cmd.Parameters.AddWithValue("@var", name);
                 int rowsAffected = cmd.ExecuteNonQuery();
                 if(rowsAffected ==1)
                 {
                        //Success notification
                 }
                 else
                 {
                        //Error notification
                 }
          }
   }
   catch(Exception ex)
   {
          //log error 
          //display friendly error to user
   }
   finally
   {
          if(conn!=null)
          {
                 //cleanup connection i.e close 
          }
   }
}

Yes, it is possible to specify your own credentials without modifying the current code. It requires a small piece of code from your part though.

Create an assembly called SomeAssembly.dll with this class :

namespace SomeNameSpace
{
    public class MyProxy : IWebProxy
    {
        public ICredentials Credentials
        {
            get { return new NetworkCredential("user", "password"); }
            //or get { return new NetworkCredential("user", "password","domain"); }
            set { }
        }

        public Uri GetProxy(Uri destination)
        {
            return new Uri("http://my.proxy:8080");
        }

        public bool IsBypassed(Uri host)
        {
            return false;
        }
    }
}

Add this to your config file :

<defaultProxy enabled="true" useDefaultCredentials="false">
  <module type = "SomeNameSpace.MyProxy, SomeAssembly" />
</defaultProxy>

This "injects" a new proxy in the list, and because there are no default credentials, the WebRequest class will call your code first and request your own credentials. You will need to place the assemble SomeAssembly in the bin directory of your CMS application.

This is a somehow static code, and to get all strings like the user, password and URL, you might either need to implement your own ConfigurationSection, or add some information in the AppSettings, which is far more easier.

passing variable from one function as argument to other functions can be done like this

define functions like this

def function1():
global a
a=input("Enter any number\t")

def function2(argument):
print ("this is the entered number - ",argument)

call the functions like this

function1()
function2(a)

In my case I had to reattach device and when it asks press "Trust this computer", then my device appears available again in xCode

Here are the proposed solutions - have you evaluated them?

• Method 1: Use a SQL Server Agent proxy account

Create a SQL Server Agent proxy account. This proxy account must use a credential that lets SQL Server Agent run the job as the account that created the package or as an account that has the required permissions.

This method works to decrypt secrets and satisfies the key requirements by user. However, this method may have limited success because the SSIS package user keys involve the current user and the current computer. Therefore, if you move the package to another computer, this method may still fail, even if the job step uses the correct proxy account. Back to the top

• Method 2: Set the SSIS Package ProtectionLevel property to ServerStorage

Change the SSIS Package ProtectionLevel property to ServerStorage. This setting stores the package in a SQL Server database and allows access control through SQL Server database roles. Back to the top

• Method 3: Set the SSIS Package ProtectionLevel property to EncryptSensitiveWithPassword

Change the SSIS Package ProtectionLevel property to EncryptSensitiveWithPassword. This setting uses a password for encryption. You can then modify the SQL Server Agent job step command line to include this password.

• Method 4: Use SSIS Package configuration files

Use SSIS Package configuration files to store sensitive information, and then store these configuration files in a secured folder. You can then change the ProtectionLevel property to DontSaveSensitive so that the package is not encrypted and does not try to save secrets to the package. When you run the SSIS package, the required information is loaded from the configuration file. Make sure that the configuration files are adequately protected if they contain sensitive information.

• Method 5: Create a package template

For a long-term resolution, create a package template that uses a protection level that differs from the default setting. This problem will not occur in future packages.

let text:String = "Hello Friend"

let searchRange:NSRange = NSRange(location:0,length: text.characters.count)

let range:Range`<Int`> = Range`<Int`>.init(start: searchRange.location, end: searchRange.length)

You might give this a try:

@echo off

for /f %%a in (sample.txt) do (
  echo %%a
  exit /b
)

edit Or, say you have four columns of data and want from the 5th row down to the bottom, try this:

@echo off

for /f "skip=4 tokens=1-4" %%a in (junkl.txt) do (
  echo %%a %%b %%c %%d
)

I ended up here looking for getting the content of an iframe without jquery, so for anyone else looking for that, it is just this:

document.querySelector('iframe[name=iframename]').contentDocument

For Eclipse Luna

Go to Help>Eclipse MarketPlace> Search for GlassFish Tools and install it.

Restart Eclipse.

Now go to servers>new>server and you will find Glassfish server.
