Just checked in Excel 2016 and this piece of code worked for me:

Sub ImmediateClear()
   Application.VBE.Windows("Immediate").SetFocus
   Application.SendKeys "^{END} ^+{HOME}{DEL}"
End Sub

The Immediate window is used to debug and evaluate expressions, execute statements, print variable values, and so forth. It allows you to enter expressions to be evaluated or executed by the development language during debugging.

To display Immediate Window, choose Debug >Windows >Immediate or press Ctrl-Alt-I

Here is an example with Immediate Window:

int Sum(int x, int y) { return (x + y);}
void main(){
int a, b, c;
a = 5;
b = 7;
c = Sum(a, b);
char temp = getchar();}

add breakpoint

ES6 React.Component doesn't auto bind methods to itself. You need to bind them yourself in constructor. Like this:

constructor (props){
  super(props);
  
  this.state = {
      loopActive: false,
      shuffleActive: false,
    };
  
  this.onToggleLoop = this.onToggleLoop.bind(this);

}

Start by considering 'Do I really want to do this?'

I have no problem referring to enums directly in HTML, but in some cases there are cleaner alternatives that don't lose type-safe-ness. For instance if you choose the approach shown in my other answer, you may have declared TT in your component something like this:

public TT = 
{
    // Enum defines (Horizontal | Vertical)
    FeatureBoxResponsiveLayout: FeatureBoxResponsiveLayout   
}

To show a different layout in your HTML, you'd have an *ngIf for each layout type, and you could refer directly to the enum in your component's HTML:

*ngIf="(featureBoxResponsiveService.layout | async) == TT.FeatureBoxResponsiveLayout.Horizontal"

This example uses a service to get the current layout, runs it through the async pipe and then compares it to our enum value. It's pretty verbose, convoluted and not much fun to look at. It also exposes the name of the enum, which itself may be overly verbose.

Alternative, that retains type safety from the HTML

Alternatively you can do the following, and declare a more readable function in your component's .ts file :

*ngIf="isResponsiveLayout('Horizontal')"

Much cleaner! But what if someone types in 'Horziontal' by mistake? The whole reason you wanted to use an enum in the HTML was to be typesafe right?

We can still achieve that with keyof and some typescript magic. This is the definition of the function:

isResponsiveLayout(value: keyof typeof FeatureBoxResponsiveLayout)
{
    return FeatureBoxResponsiveLayout[value] == this.featureBoxResponsiveService.layout.value;
}

Note the usage of FeatureBoxResponsiveLayout[string] which converts the string value passed in to the numeric value of the enum.

This will give an error message with an AOT compilation if you use an invalid value.

Argument of type '"H4orizontal"' is not assignable to parameter of type '"Vertical" | "Horizontal"

Currently VSCode isn't smart enough to underline H4orizontal in the HTML editor, but you'll get the warning at compile time (with --prod build or --aot switch). This also may be improved upon in a future update.

Since the answer for me was buried in the comments. For SQL Server 2012 and beyond, you can use the following:

BACKUP LOG Database TO DISK='NUL:'
DBCC SHRINKFILE (Database_Log, 1)

Use type="application/javascript"

In case of HTML5, the type attribute is obsolete, you may remove it. Note: that it defaults to "text/javascript" according to w3.org, so I would suggest to add the "application/javascript" instead of removing it.

http://www.w3.org/TR/html5/scripting-1.html#attr-script-type
The type attribute gives the language of the script or format of the data. If the attribute is present, its value must be a valid MIME type. The charset parameter must not be specified. The default, which is used if the attribute is absent, is "text/javascript".

Use "application/javascript", because "text/javascript" is obsolete:

RFC 4329: http://www.rfc-editor.org/rfc/rfc4329.txt

3. Deployed Scripting Media Types and Compatibility

   Various unregistered media types have been used in an ad-hoc fashion to label and exchange programs written in ECMAScript and JavaScript. These include:

   +-----------------------------------------------------+ | text/javascript | text/ecmascript | | text/javascript1.0 | text/javascript1.1 | | text/javascript1.2 | text/javascript1.3 | | text/javascript1.4 | text/javascript1.5 | | text/jscript | text/livescript | | text/x-javascript | text/x-ecmascript | | application/x-javascript | application/x-ecmascript | | application/javascript | application/ecmascript | +-----------------------------------------------------+

Use of the "text" top-level type for this kind of content is known to be problematic. This document thus defines text/javascript and text/
ecmascript but marks them as "obsolete". Use of experimental and
unregistered media types, as listed in part above, is discouraged.
The media types,

  * application/javascript
  * application/ecmascript

which are also defined in this document, are intended for common use and should be used instead.

This document defines equivalent processing requirements for the
types text/javascript, text/ecmascript, and application/javascript.
Use of and support for the media type application/ecmascript is
considerably less widespread than for other media types defined in
this document. Using that to its advantage, this document defines
stricter processing rules for this type to foster more interoperable
processing.

x-javascript is experimental, don't use it.

You have to call DataReader.Read to fetch the result:

SqlDataReader dr = cmd10.ExecuteReader();
if (dr.Read()) 
{
    // read data for first record here
}

DataReader.Read() returns a bool indicating if there are more blocks of data to read, so if you have more than 1 result, you can do:

while (dr.Read()) 
{
    // read data for each record here
}

I had this problem along with mismatch in ITERATOR_DEBUG_LEVEL. As a sunday-evening problem after all seemed ok and good to go, I was put out for some time. Working in de VS2017 IDE (Solution Explorer) I had recently added/copied a sourcefile reference to my project (ctrl-drag) from another project. Looking into properties->C/C++/Preprocessor - at source file level, not project level - I noticed that in a Release configuration _DEBUG was specified instead of NDEBUG for this source file. Which was all the change needed to get rid of the problem.

Please try this, if you want to fetch first/last.

{{#each list}}

    {{#if @first}}
        <div class="active">
    {{else}}
        <div>
    {{/if}}

{{/each}}


{{#each list}}

    {{#if @last}}
        <div class="last-element">
    {{else}}
        <div>
    {{/if}}

{{/each}}

The fastest is datediff, e.g.

select dateadd(d, datediff(d,0, [datecolumn]), 0), other..
from tbl

But if you only need to use the value, then you can skip the dateadd, e.g.

select ...
WHERE somedate <= datediff(d, 0, getdate())

where the expression datediff(d, 0, getdate()) is sufficient to return today's date without time portion.

Try this:

<input type="number" max="???" min="???" step="0.5" id="myInput"/>

$("#myInput").attr({
   "max" : 10,
   "min" : 2
});

Note:This will set max and min value only to single input

Here is a standalone solution:

$(window).load(function() {
  $('img').each(function() {
    if ( !this.complete
    ||   typeof this.naturalWidth == "undefined"
    ||   this.naturalWidth == 0                  ) {
      // image was broken, replace with your new image
      this.src = 'http://www.tranism.com/weblog/images/broken_ipod.gif';
    }
  });
});

//defines an array of 280 pointers (1120 or 2240 bytes)
int  *pointer1 [280];

//defines a pointer (4 or 8 bytes depending on 32/64 bits platform)
int (*pointer2)[280];      //pointer to an array of 280 integers
int (*pointer3)[100][280]; //pointer to an 2D array of 100*280 integers

Using pointer2 or pointer3 produce the same binary except manipulations as ++pointer2 as pointed out by WhozCraig.

I recommend using typedef (producing same binary code as above pointer3)

typedef int myType[100][280];
myType *pointer3;

Note: Since C++11, you can also use keyword using instead of typedef

using myType = int[100][280];
myType *pointer3;

in your example:

myType *pointer;                // pointer creation
pointer = &tab1;                // assignation
(*pointer)[5][12] = 517;        // set (write)
int myint = (*pointer)[5][12];  // get (read)

Note: If the array tab1 is used within a function body => this array will be placed within the call stack memory. But the stack size is limited. Using arrays bigger than the free memory stack produces a stack overflow crash.

The full snippet is online-compilable at gcc.godbolt.org

int main()
{
    //defines an array of 280 pointers (1120 or 2240 bytes)
    int  *pointer1 [280];
    static_assert( sizeof(pointer1) == 2240, "" );

    //defines a pointer (4 or 8 bytes depending on 32/64 bits platform)
    int (*pointer2)[280];      //pointer to an array of 280 integers
    int (*pointer3)[100][280]; //pointer to an 2D array of 100*280 integers  
    static_assert( sizeof(pointer2) == 8, "" );
    static_assert( sizeof(pointer3) == 8, "" );

    // Use 'typedef' (or 'using' if you use a modern C++ compiler)
    typedef int myType[100][280];
    //using myType = int[100][280];

    int tab1[100][280];

    myType *pointer;                // pointer creation
    pointer = &tab1;                // assignation
    (*pointer)[5][12] = 517;        // set (write)
    int myint = (*pointer)[5][12];  // get (read)

    return myint;
}

Well, the "-a" mail and mailx in Centos7 is "attach file" not "append header." My shortest path to a solution on Centos7 from here: stackexchange.com

Basically:

yum install mutt
mutt -e 'set content_type=text/html' -s 'My subject' [email protected] < msg.html

IN KOTLIN :

Suppose that you have a String like this :

private val phoneNumber="9121111111"

At first you should get the first one :

val firstChar=phoneNumber.slice(0..0)

At second you can check the first char that return a Boolean :

firstChar.isInt() // or isFloat()

I implemented the similar thing this way:

1. Use TextBoxFor to display date in required format and make the field readonly.

@Html.TextBoxFor(Model => Model.AuditDate, "{0:dd-MMM-yyyy}", new{@class="my-style", @readonly=true})

2. Give zero outline and zero border to TextBox in css.

.my-style {
    outline: none;
    border: none;
}

And......Its done :)

To add to MattDMo's answer, you can get the exact font that's used on Linux like so (the example is from Xubuntu 14.04):

$ fc-match Monospace
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"

I had this issue recently and I resolved it by simply rolling IE8 back to IE7.

My guess is that IE7 had these files as a wrapper for working on Windows XP, but IE8 was likely made to work with Vista/7 so it removed the files because the later editions just don't use the shim.

you can use this query

SUM(NULLIF(conversion_units, '')::numeric)

You can use CurrentDirectory property.

Dim WshShell, strCurDir
Set WshShell = CreateObject("WScript.Shell")
strCurDir    = WshShell.CurrentDirectory
WshShell.Run strCurDir & "\attribute.exe", 0
Set WshShell = Nothing

SELECT DEPTNAME
FROM(SELECT D.DEPTNAME,COUNT(EMPID) AS TOTEMP
     FROM DEPT AS D,EMPLOYEE AS E
     WHERE D.DEPTID=E.DEPTID AND SALARY>1000
     GROUP BY D.DEPTID
     )
WHERE TOTEMP>2;

If you will invoke the script with source, you can use return <x> where <x> will be the script exit status (use a non-zero value for error or false). But if you invoke an executable script (i.e., directly with its filename), the return statement will result in a complain (error message "return: can only `return' from a function or sourced script").

If exit <x> is used instead, when the script is invoked with source, it will result in exiting the shell that started the script, but an executable script will just terminate, as expected.

To handle either case in the same script, you can use

return <x> 2> /dev/null || exit <x>

This will handle whichever invocation may be suitable. That is assuming you will use this statement at the script's top level. I would advise against directly exiting the script from within a function.

Note: <x> is supposed to be just a number.

Did you try this?

new File("<PATH OF YOUR FILE>").toURI().toString();

See if this example provides any clarification. Basically you configure a set of routes and include partial templates based on the route. Setting ng-view in your main index.html allows you to inject those partial views.

The config portion looks like this:

  .config(['$routeProvider', function($routeProvider) {
    $routeProvider
      .when('/', {controller:'ListCtrl', templateUrl:'list.html'})
      .otherwise({redirectTo:'/'});
  }])

The point of entry for injecting the partial view into your main template is:

<div class="container" ng-view=""></div>

Use "&" instead of "&".

I noticed that this question was not marked as answered after 2 years - I think the closest answer is Richards, but it can be simplified quite a lot to this:

list1.Concat(list2)
    .ToLookup(p => p.Name)
    .Select(g => g.Aggregate((p1, p2) => new Person 
    {
        Name = p1.Name,
        Value = p1.Value, 
        Change = p2.Value - p1.Value 
    }));

Although this won't error in the case where you have duplicate names in either set.

Some other answers have suggested using unioning - this is definitely not the way to go as it will only get you a distinct list, without doing the combining.

I'm late to the party, but I had this same issue working with Java 8.

This is what worked for me, on the HttpServletRequest request object.

request.getHeader("origin");

and

request.getHeader("referer");

How I came to that conclusion:

I have a java app running on http://localhost:3000 making a Http Post to another java app I have running on http://localhost:8080.

From the Java code running on http://localhost:8080 I couldn't get the http://localhost:3000 from the HttpServletRequest using the answers above. For me using the getHeader method with the correct string input worked.

request.getHeader("origin") gave me "http://localhost:3000" which is what I wanted.

request.getHeader("referer") gave me "http://localhost:3000/xxxx" where xxxx is full URL I have from the requesting app.

len() 

it will count the element in the list, tuple and string and dictionary, eg.

>>> mylist = [1,2,3] #list
>>> len(mylist)
3
>>> word = 'hello' # string 
>>> len(word)
5
>>> vals = {'a':1,'b':2} #dictionary
>>> len(vals)
2
>>> tup = (4,5,6) # tuple 
>>> len(tup)
3

To learn Python you can use byte of python , it is best ebook for python beginners.

This only applies to question 1.

I have an app that runs on Windows and uses a multi-line MFC editor box.
The editor box expects CRLF linebreaks, but I need to parse the text enterred
with some really big/nasty regexs'.

I didn't want to be stressing about this while writing the regex, so
I ended up normalizing back and forth between the parser and editor so that
the regexs' just use \n. I also trap paste operations and convert them for the boxes.

This does not take much time.
This is what I use.

 boost::regex  CRLFCRtoLF (
     " \\r\\n | \\r(?!\\n) "
     , MODx);

 boost::regex  CRLFCRtoCRLF (
     " \\r\\n?+ | \\n "
     , MODx);


 // Convert (All style) linebreaks to linefeeds 
 // ---------------------------------------
 void ReplaceCRLFCRtoLF( string& strSrc, string& strDest )
 {
    strDest  = boost::regex_replace ( strSrc, CRLFCRtoLF, "\\n" );
 }

 // Convert linefeeds to linebreaks (Windows) 
 // ---------------------------------------
 void ReplaceCRLFCRtoCRLF( string& strSrc, string& strDest )
 {
    strDest  = boost::regex_replace ( strSrc, CRLFCRtoCRLF, "\\r\\n" );
 }

To extend Rodrigo's solution a little - for requests that are executed frequently, you may only want to display the loading image if the request takes more than a minimum time interval, otherwise the image will be continually popping up and quickly disappearing

var loading = false;

$.ajaxSetup({
    beforeSend: function () {
        // Display loading icon if AJAX call takes >1 second
        loading = true;
        setTimeout(function () {
            if (loading) {
                // show loading image
            }
        }, 1000);            
    },
    complete: function () {
        loading = false;
        // hide loading image
    }
});

Add log4jExposeWebAppRoot -> false in your web.xml. It works with me :)

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>path/log4j.properties</param-value>
</context-param>
<context-param>
    <param-name>log4jExposeWebAppRoot</param-name>
    <param-value>false</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

For me the solution was to set the version of the maven compiler plugin to 3.8.0 and specify the release (9 for in your case, 11 in mine)

    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.0</version>
      <configuration>
        <release>11</release>
      </configuration>
    </plugin>

The Bootstrap Glyphicons are fonts. This means it can be changed like any other text through CSS styling.

CSS:

<style>
   .glyphicon-plus {
       color: #F00; 
   }
</style>

HTML:

<span class="glyphicon glyphicon-plus"></span>

Example:

<!doctype html>
<html>
<head>
<title>Glyphicon Colors</title>
<link href="css/bootstrap.min.css" rel="stylesheet">
<style>
   .glyphicon-plus {
        color: #F00;    
   }
</style>
</head>

<body>
    <span class="glyphicon glyphicon-plus"></span>
</body>
</html>

Watch the course Up and Running with Bootstrap 3 by Jen Kramer, or watch the individual lesson on Overriding core CSS with custom styles.

In engineering data, it is common to see the # symbol in the first column used to signal a comment.

I use the ostermiller CSV parsing library for Java to read and process such files. That library allows you to set the comment character. After the parse operation you get an array just containing the real data, no comments.

If your info.plist is shown as a property list (and not xml), the text you need to enter for the key is:
App Uses Non-Exempt Encryption

Starting an Activity is not the right approach for this behavior. Instead have your BroadcastReceiver use an intent to start a Service which can continue to run as long as possible. (See http://developer.android.com/reference/android/app/Service.html#ProcessLifecycle)

See also Persistent service

Slightly more compact:

df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df = df.sort_index()
print(df)

Note:

• sort has been deprecated, replaced by sort_index for this scenario
• preferable not to use inplace as it is usually harder to read and prevents chaining. See explanation in answer here: Pandas: peculiar performance drop for inplace rename after dropna

Use git reset:

git reset --hard "Version 1.0 Revision 1.5"

(assuming that the specified string is the tag).

It is important to note that you could use Emmet to achieve the same result. First, check what Emmet can do for you at https://emmet.io/

In a nutshell, with Emmet, you can expand a string into a complexe HTML markup as shown in the examples below:

Example #1

ul>li*5

... will produce

<ul>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
</ul>

Example #2

div#header+div.page+div#footer.class1.class2.class3

... will produce

<div id="header"></div>
<div class="page"></div>
<div id="footer" class="class1 class2 class3"></div>

And list goes on. There are more examples at https://docs.emmet.io/abbreviations/syntax/

And there is a library for doing that using jQuery. It's called Emmet.js and available at https://github.com/christiansandor/Emmet.js

EDIT based on comments:

If you have line breaks in your result set and want to remove them, make your query this way:

SELECT
    REPLACE(REPLACE(YourColumn1,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn2,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn3,CHAR(13),' '),CHAR(10),' ')
   --^^^^^^^^^^^^^^^           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   --only add the above code to strings that are having line breaks, not to numbers or dates
   FROM YourTable...
   WHERE ...

This will replace all the line breaks with a space character.

Run this to "get" all characters permitted in a char() and varchar():

;WITH AllNumbers AS
(
    SELECT 1 AS Number
    UNION ALL
    SELECT Number+1
        FROM AllNumbers
        WHERE Number+1<256
)
SELECT Number AS ASCII_Value,CHAR(Number) AS ASCII_Char FROM AllNumbers
OPTION (MAXRECURSION 256)

OUTPUT:

make sure you have save .TS file before compiling.

There is the solution if you need only outline without border. It's not mine. I got if from Bootstrap css file. If you specify outline: 1px auto certain_color, you'll get thin outer line around div of certain color. In this case the specified width has no matter, even if you specify 10 px width, anyway it will be thin line. The key word in mentioned rule is "auto".
If you need outline with rounded corners and certain width, you may add css rule on border with needed width and same color. It makes outline thicker.

You are trying to access the first element lstpp.get(0) of an empty array. Just add an element to your array and check for !lstpp.isEmpty() before accessing an element

        var eventids = GetEventIdsByEventDate(DateTime.Now);
        var result = eventsdb.Where(e => eventids.Contains(e));

If you are returnning List<EventFeed> inside the method, you should change the method return type from IEnumerable<EventFeed> to List<EventFeed>.

Class that will call the methods:

namespace myNamespace
{
    public class myClass
    {
        public static void voidMethodWithoutParameters()
        {
            // code here
        }
        public static string stringReturnMethodWithParameters(string param1, string param2)
        {
            // code here
            return "output";
        }
    }
}

Calling myClass static methods using Reflection:

var myClassType = Assembly.GetExecutingAssembly().GetType(GetType().Namespace + ".myClass");
                    
// calling my void Method that has no parameters.
myClassType.GetMethod("voidMethodWithoutParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, null);

// calling my string returning Method & passing to it two string parameters.
Object methodOutput = myClassType.GetMethod("stringReturnMethodWithParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, new object[] { "value1", "value1" });
Console.WriteLine(methodOutput.ToString());

Note: I don't need to instantiate an object of myClass to use it's methods, as the methods I'm using are static.

If you are in the iframe context,

you could do

const currentIframeHref = new URL(document.location.href);
const urlOrigin = currentIframeHref.origin;
const urlFilePath = decodeURIComponent(currentIframeHref.pathname);

If you are in the parent window/frame, then you can use https://stackoverflow.com/a/938195/2305243 's answer, which is

document.getElementById("iframe_id").contentWindow.location.href

Just use the split function. It returns a list, so you can keep the first element:

>>> s1.split(':')
['Username', ' How are you today?']
>>> s1.split(':')[0]
'Username'

Ok I have found a solution. The problem is that the site uses SSLv3. And I know that there are some problems in the openssl module. Some time ago I had the same problem with the SSL versions.

<?php
function getSSLPage($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSLVERSION,3); 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

var_dump(getSSLPage("https://eresearch.fidelity.com/eresearch/evaluate/analystsOpinionsReport.jhtml?symbols=api"));
?>

When you set the SSL Version with curl to v3 then it works.

Edit:

Another problem under Windows is that you don't have access to the certificates. So put the root certificates directly to curl.

http://curl.haxx.se/docs/caextract.html

here you can download the root certificates.

curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/certs/cacert.pem");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

Then you can use the CURLOPT_SSL_VERIFYPEER option with true otherwise you get an error.

"none" does not do what you assume it does. In order to "clear" a CSS property, you must set it back to its default, which is defined by the CSS standard. Thus you should look up the defaults in your favorite reference.

table.other {
    width: auto;
    min-width: 0;
    display:table;
}

Yes, a menu gives you the bar but it doesn't give you any items to put in the bar. You need something like (from one of my own projects):

<!-- Menu. -->
<Menu Width="Auto" Height="20" Background="#FFA9D1F4" DockPanel.Dock="Top">
    <MenuItem Header="_Emulator">
    <MenuItem Header="Load..." Click="MenuItem_Click" />
    <MenuItem Header="Load again" Click="menuEmulLoadLast" />
    <Separator />
    <MenuItem Click="MenuItem_Click">
        <MenuItem.Header>
            <DockPanel>
                <TextBlock>Step</TextBlock>
                <TextBlock Width="10"></TextBlock>
                <TextBlock HorizontalAlignment="Right">F2</TextBlock>
            </DockPanel>
        </MenuItem.Header>
    </MenuItem>

Note: According to JDN96, the answer below may cause a memory leak by repeatedly destroying and recreating frames. However, I have not tested to verify this myself.

One way to switch frames in tkinter is to destroy the old frame then replace it with your new frame.

I have modified Bryan Oakley's answer to destroy the old frame before replacing it. As an added bonus, this eliminates the need for a container object and allows you to use any generic Frame class.

# Multi-frame tkinter application v2.3
import tkinter as tk

class SampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self._frame = None
        self.switch_frame(StartPage)

    def switch_frame(self, frame_class):
        """Destroys current frame and replaces it with a new one."""
        new_frame = frame_class(self)
        if self._frame is not None:
            self._frame.destroy()
        self._frame = new_frame
        self._frame.pack()

class StartPage(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is the start page").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Open page one",
                  command=lambda: master.switch_frame(PageOne)).pack()
        tk.Button(self, text="Open page two",
                  command=lambda: master.switch_frame(PageTwo)).pack()

class PageOne(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is page one").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Return to start page",
                  command=lambda: master.switch_frame(StartPage)).pack()

class PageTwo(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is page two").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Return to start page",
                  command=lambda: master.switch_frame(StartPage)).pack()

if __name__ == "__main__":
    app = SampleApp()
    app.mainloop()

Explanation

switch_frame() works by accepting any Class object that implements Frame. The function then creates a new frame to replace the old one.

• Deletes old _frame if it exists, then replaces it with the new frame.
• Other frames added with .pack(), such as menubars, will be unaffected.
• Can be used with any class that implements tkinter.Frame.
• Window automatically resizes to fit new content

Version History

v2.3

- Pack buttons and labels as they are initialized

v2.2

- Initialize `_frame` as `None`.
- Check if `_frame` is `None` before calling `.destroy()`.

v2.1.1

- Remove type-hinting for backwards compatibility with Python 3.4.

v2.1

- Add type-hinting for `frame_class`.

v2.0

- Remove extraneous `container` frame.
    - Application now works with any generic `tkinter.frame` instance.
- Remove `controller` argument from frame classes.
    - Frame switching is now done with `master.switch_frame()`.

v1.6

- Check if frame attribute exists before destroying it.
- Use `switch_frame()` to set first frame.

v1.5

  - Revert 'Initialize new `_frame` after old `_frame` is destroyed'.
      - Initializing the frame before calling `.destroy()` results
        in a smoother visual transition.

v1.4

- Pack frames in `switch_frame()`.
- Initialize new `_frame` after old `_frame` is destroyed.
    - Remove `new_frame` variable.

v1.3

- Rename `parent` to `master` for consistency with base `Frame` class.

v1.2

- Remove `main()` function.

v1.1

- Rename `frame` to `_frame`.
    - Naming implies variable should be private.
- Create new frame before destroying old frame.

v1.0

- Initial version.

For Windows Forms you can control cursor position (and selection) with txtbox.SelectionStart and txtbox.SelectionLength properties. If you want to set caret to end try this:

txtbox.SelectionStart = txtbox.Text.Length;
txtbox.SelectionLength = 0;

For WPF see this question.

window.location.href, this as saved my life in webview from Android 5.1. The page don't reload with location.reload() in this version from Android.

Try like this.. Eg : www.example.com?id=1

$.urlParam = function (name) {
    var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.search);
    return (results !== null) ? results[1] || 0 : false;
}
console.log($.urlParam('id'));

Hope it helps. :)

function ms_escape_string($data) {
        if ( !isset($data) or empty($data) ) return '';
        if ( is_numeric($data) ) return $data;

        $non_displayables = array(
            '/%0[0-8bcef]/',            // url encoded 00-08, 11, 12, 14, 15
            '/%1[0-9a-f]/',             // url encoded 16-31
            '/[\x00-\x08]/',            // 00-08
            '/\x0b/',                   // 11
            '/\x0c/',                   // 12
            '/[\x0e-\x1f]/'             // 14-31
        );
        foreach ( $non_displayables as $regex )
            $data = preg_replace( $regex, '', $data );
        $data = str_replace("'", "''", $data );
        return $data;
    }

Some of the code here was ripped off from CodeIgniter. Works well and is a clean solution.

EDIT: There are plenty of issues with that code snippet above. Please don't use this without reading the comments to know what those are. Better yet, please don't use this at all. Parameterized queries are your friends: http://php.net/manual/en/pdo.prepared-statements.php

Simple function to alert contents of an object or an array .
Call this function with an array or string or an object it alerts the contents.

Function

function print_r(printthis, returnoutput) {
    var output = '';

    if($.isArray(printthis) || typeof(printthis) == 'object') {
        for(var i in printthis) {
            output += i + ' : ' + print_r(printthis[i], true) + '\n';
        }
    }else {
        output += printthis;
    }
    if(returnoutput && returnoutput == true) {
        return output;
    }else {
        alert(output);
    }
}

Usage

var data = [1, 2, 3, 4];
print_r(data);

You can find the most up to date answer for the value in your project just execute the

mvn3 help:effective-pom

command and find the <build> ... <directory> tag's value in the result aka in the effective-pom. It will show the value of the Super POM unless you have overwritten.

(Edited to add new info): consider whether using the Combine framework can help you accomplish what you wanted, rather than using KVO

Yes and no. KVO works on NSObject subclasses much as it always has. It does not work for classes that don't subclass NSObject. Swift does not (currently at least) have its own native observation system.

(See comments for how to expose other properties as ObjC so KVO works on them)

See the Apple Documentation for a full example.

For anyone coming across this years later:

TL;DR check your pip version (2 vs 3)

I had this same issue and it was not fixed by running pip install simplejson despite pip insisting that it was installed. Then I realized that I had both python 2 and python 3 installed.

> python -V
Python 2.7.12
> pip -V
pip 9.0.1 from /usr/local/lib/python3.5/site-packages (python 3.5)

Installing with the correct version of pip is as easy as using pip2:

> pip2 install simplejson

and then python 2 can import simplejson fine.

Your OneThread Class also should implement Serializable. All the sub classes and inner sub classes must implements Serializable.

this is worked for me...

So you want to fire Ajax calls to the servlet? For that you need the XMLHttpRequest object in JavaScript. Here's a Firefox compatible example:

<script>
    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function() {
        if (xhr.readyState == 4) {
            var data = xhr.responseText;
            alert(data);
        }
    }
    xhr.open('GET', '${pageContext.request.contextPath}/myservlet', true);
    xhr.send(null);
</script>

This is however very verbose and not really crossbrowser compatible. For the best crossbrowser compatible way of firing ajaxical requests and traversing the HTML DOM tree, I recommend to grab jQuery. Here's a rewrite of the above in jQuery:

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
    $.get('${pageContext.request.contextPath}/myservlet', function(data) {
        alert(data);
    });
</script>

Either way, the Servlet on the server should be mapped on an url-pattern of /myservlet (you can change this to your taste) and have at least doGet() implemented and write the data to the response as follows:

String data = "Hello World!";
response.setContentType("text/plain");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(data);

This should show Hello World! in the JavaScript alert.

You can of course also use doPost(), but then you should use 'POST' in xhr.open() or use $.post() instead of $.get() in jQuery.

Then, to show the data in the HTML page, you need to manipulate the HTML DOM. For example, you have a

<div id="data"></div>

in the HTML where you'd like to display the response data, then you can do so instead of alert(data) of the 1st example:

document.getElementById("data").firstChild.nodeValue = data;

In the jQuery example you could do this in a more concise and nice way:

$('#data').text(data);

To go some steps further, you'd like to have an easy accessible data format to transfer more complex data. Common formats are XML and JSON. For more elaborate examples on them, head to How to use Servlets and Ajax?

Get the library from http://commons.apache.org/net/download_net.cgi

//NTP server list: http://tf.nist.gov/tf-cgi/servers.cgi
public static final String TIME_SERVER = "time-a.nist.gov";

public static long getCurrentNetworkTime() {
    NTPUDPClient timeClient = new NTPUDPClient();
    InetAddress inetAddress = InetAddress.getByName(TIME_SERVER);
    TimeInfo timeInfo = timeClient.getTime(inetAddress);
    //long returnTime = timeInfo.getReturnTime();   //local device time
    long returnTime = timeInfo.getMessage().getTransmitTimeStamp().getTime();   //server time

    Date time = new Date(returnTime);
    Log.d(TAG, "Time from " + TIME_SERVER + ": " + time);

    return returnTime;
}

getReturnTime() is same as System.currentTimeMillis().

getReceiveTimeStamp() or getTransmitTimeStamp() method should be used.

You can see the difference after setting system time to 1 hour ago.

local time :
System.currentTimeMillis()
timeInfo.getReturnTime()
timeInfo.getMessage().getOriginateTimeStamp().getTime()

NTP server time :
timeInfo.getMessage().getReceiveTimeStamp().getTime()
timeInfo.getMessage().getTransmitTimeStamp().getTime()

Actually what you are searching is: Optional.map. Your code would then look like:

object.map(o -> "result" /* or your function */)
      .orElseThrow(MyCustomException::new);

I would rather omit passing the Optional if you can. In the end you gain nothing using an Optional here. A slightly other variant:

public String getString(Object yourObject) {
  if (Objects.isNull(yourObject)) { // or use requireNonNull instead if NullPointerException suffices
     throw new MyCustomException();
  }
  String result = ...
  // your string mapping function
  return result;
}

If you already have the Optional-object due to another call, I would still recommend you to use the map-method, instead of isPresent, etc. for the single reason, that I find it more readable (clearly a subjective decision ;-)).

The function removeItem actually contains an error, which makes the form button do it's default behaviour (submitting the form). The javascript error console will usually give a pointer in this case.

Check out the function removeItem in the javascript part:

The line:

rows[rows.length-1].html('');

doesn't work. Try this instead:

rows.eq(rows.length-1).html('');

Just convert it to int:

char registered = '®';
int code = (int) registered;

In fact there's an implicit conversion from char to int so you don't have to specify it explicitly as I've done above, but I would do so in this case to make it obvious what you're trying to do.

This will give the UTF-16 code unit - which is the same as the Unicode code point for any character defined in the Basic Multilingual Plane. (And only BMP characters can be represented as char values in Java.) As Andrzej Doyle's answer says, if you want the Unicode code point from an arbitrary string, use Character.codePointAt().

Once you've got the UTF-16 code unit or Unicode code points, but of which are integers, it's up to you what you do with them. If you want a string representation, you need to decide exactly what kind of representation you want. (For example, if you know the value will always be in the BMP, you might want a fixed 4-digit hex representation prefixed with U+, e.g. "U+0020" for space.) That's beyond the scope of this question though, as we don't know what the requirements are.

Working from what you've given I'll assume you want to check that someone has NOT entered any letters other than the ones you've listed. For that to work you want to search for any characters other than those listed:

[^A-Za-z0-9_.]

And use that in a match in your code, something like:

if ( /[^A-Za-z0-9_.]/.match( your_input_string ) ) {
   alert( "you have entered invalid data" );
}

Hows that?

Try to check for existence:

IF NOT EXISTS (SELECT * FROM dbo.Employee WHERE ID = @SomeID)

    INSERT INTO dbo.Employee(Col1, ..., ColN)
    VALUES(Val1, .., ValN)

ELSE

    UPDATE dbo.Employee
    SET Col1 = Val1, Col2 = Val2, ...., ColN = ValN
    WHERE ID = @SomeID

You could easily wrap this into a stored procedure and just call that stored procedure from the outside (e.g. from a programming language like C# or whatever you're using).

Update: either you can just write this entire statement in one long string (doable - but not really very useful) - or you can wrap it into a stored procedure:

CREATE PROCEDURE dbo.InsertOrUpdateEmployee
       @ID INT,
       @Name VARCHAR(50),
       @ItemName VARCHAR(50),  
       @ItemCatName VARCHAR(50),
       @ItemQty DECIMAL(15,2)
AS BEGIN
    IF NOT EXISTS (SELECT * FROM dbo.Table1 WHERE ID = @ID)
       INSERT INTO dbo.Table1(ID, Name, ItemName, ItemCatName, ItemQty)
       VALUES(@ID, @Name, @ItemName, @ItemCatName, @ItemQty)
    ELSE
       UPDATE dbo.Table1
       SET Name = @Name,
           ItemName = @ItemName,
           ItemCatName = @ItemCatName,
           ItemQty = @ItemQty
       WHERE ID = @ID
END

and then just call that stored procedure from your ADO.NET code

While it's true that @RequestBody must map to a single object, that object can be a Map, so this gets you a good way to what you are attempting to achieve (no need to write a one off backing object):

@RequestMapping(value = "/Test", method = RequestMethod.POST)
@ResponseBody
public boolean getTest(@RequestBody Map<String, String> json) {
   //json.get("str1") == "test one"
}

You can also bind to Jackson's ObjectNode if you want a full JSON tree:

public boolean getTest(@RequestBody ObjectNode json) {
   //json.get("str1").asText() == "test one"

    div{
    border-left:solid red 3px;
    border-right:solid violet 4px;
    border-top:solid blue 4px;
    border-bottom:solid green 4px;
    background:grey;
    width:100px; height:50px
}

myList.GroupBy(test => test.id)
      .Select(grp => grp.First());

Edit: as getting this IEnumerable<> into a List<> seems to be a mystery to many people, you can simply write:

var result = myList.GroupBy(test => test.id)
                   .Select(grp => grp.First())
                   .ToList();

But one is often better off working with the IEnumerable rather than IList as the Linq above is lazily evaluated: it doesn't actually do all of the work until the enumerable is iterated. When you call ToList it actually walks the entire enumerable forcing all of the work to be done up front. (And may take a little while if your enumerable is infinitely long.)

The flipside to this advice is that each time you enumerate such an IEnumerable the work to evaluate it has to be done afresh. So you need to decide for each case whether it is better to work with the lazily evaluated IEnumerable or to realize it into a List, Set, Dictionary or whatnot.

These are known as postfix and prefix operators. Both will add 1 to the variable but there is a difference in the result of the statement.

int x = 0;
int y = 0;
y = ++x;            // result: y=1, x=1

int x = 0;
int y = 0;
y = x++;            // result: y=0, x=1

There are two ways of storing a color with alpha. The first is exactly as you see it, with each component as-is. The second is to use pre-multiplied alpha, where the color values are multiplied by the alpha after converting it to the range 0.0-1.0; this is done to make compositing easier. Ordinarily you shouldn't notice or care which way is implemented by any particular engine, but there are corner cases where you might, for example if you tried to increase the opacity of the color. If you use rgba(0, 0, 0, 0) you are less likely to to see a difference between the two approaches.

What you are after is called partial function application.

Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.

Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:

Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.

This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?

Example:

var fr = partial(f, 1, 2, 3);

// now, when you invoke fr() it will invoke f(1,2,3)
fr();

Again, see that question for the details.

Given

d = [[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]

and your specific question: How can I remove the brackets?

Using list comprehension :

new_d = [i[0] for i in d]

will give you this

[180.0, 173.8, 164.2, 156.5, 147.2, 138.2]

then you can access individual items with the appropriate index, e.g., new_d[0] will give you 180.0 etc which you can then use for math.

If you are going to have a collection of data, you will have some sort of bracket or parenthesis.

Note, this solution is aimed specifically at your question/problem, it doesn't provide a generalized solution. I.e., it will work for your case.

  int base2(String bits) {
    int ans = 0;
    for (int i = bits.length() - 1, f = 1; i >= 0; i--) {
      ans += f * (bits.charAt(i) - '0');
      f <<= 1;
    }
    return ans;
  }

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

In some cases, such as routing with a component that's wrapped with redux-form, replacing the Route component argument on this JSX element:

<Route path="speaker" component={Speaker}/>

With the Route render argument like the following, will fix issue:

<Route path="speaker" render={props => <Speaker {...props} />} />

From the CLI:

php -r 'phpinfo();'

The below code helps, if you use Gradle. Allows you to easily remove unneeded Google services (presuming you're using them) to get back below the 65k threshold. All credit to this post: https://gist.github.com/dmarcato/d7c91b94214acd936e42

Edit 2014-10-22: There's been a lot of interesting discussion on the gist referenced above. TLDR? look at this one: https://gist.github.com/Takhion/10a37046b9e6d259bb31

Paste this code at the bottom of your build.gradle file and adjust the list of google services you do not need:

def toCamelCase(String string) {
    String result = ""
    string.findAll("[^\\W]+") { String word ->
        result += word.capitalize()
    }
    return result
}

afterEvaluate { project ->
    Configuration runtimeConfiguration = project.configurations.getByName('compile')
    ResolutionResult resolution = runtimeConfiguration.incoming.resolutionResult
    // Forces resolve of configuration
    ModuleVersionIdentifier module = resolution.getAllComponents().find { it.moduleVersion.name.equals("play-services") }.moduleVersion

    String prepareTaskName = "prepare${toCamelCase("${module.group} ${module.name} ${module.version}")}Library"
    File playServiceRootFolder = project.tasks.find { it.name.equals(prepareTaskName) }.explodedDir

    Task stripPlayServices = project.tasks.create(name: 'stripPlayServices', group: "Strip") {
        inputs.files new File(playServiceRootFolder, "classes.jar")
        outputs.dir playServiceRootFolder
        description 'Strip useless packages from Google Play Services library to avoid reaching dex limit'

        doLast {
            copy {
                from(file(new File(playServiceRootFolder, "classes.jar")))
                into(file(playServiceRootFolder))
                rename { fileName ->
                    fileName = "classes_orig.jar"
                }
            }
            tasks.create(name: "stripPlayServices" + module.version, type: Jar) {
                destinationDir = playServiceRootFolder
                archiveName = "classes.jar"
                from(zipTree(new File(playServiceRootFolder, "classes_orig.jar"))) {
                    exclude "com/google/ads/**"

                }
            }.execute()
            delete file(new File(playServiceRootFolder, "classes_orig.jar"))
        }

    project.tasks.findAll { it.name.startsWith('prepare') && it.name.endsWith('Dependencies') }.each { Task task ->
        task.dependsOn stripPlayServices

}

The top answer is much better in terms of breadth and depth of information given, but it seems like if you wanted your problem fixed almost immediately, and don't mind trodding on some of the basic principles of version control, you could ...

1. Switch to master

   $ git checkout upstream master
   

2. Delete your unwanted branch. (Note: it must be have the -D, instead of the normal -d flag because your branch is many commits ahead of the master.)

   $ git branch -d <branch_name>
   

3. Create a new branch

   $ git checkout -b <new_branch_name>
   

I would use a StringBuilder class for doing string manipulation as it will more efficient (being mutable)

string flights = "Flight A, B,C,D";
StringBuilder message = new StringBuilder();
message.Append("Hi We have these flights for you: ");
message.Append(flights);
message.Append(" . Which one do you want?");

There's a super small section in the DOCs that shows how to find/find_all direct children.

https://www.crummy.com/software/BeautifulSoup/bs4/doc/#the-recursive-argument

In your case as you want link1 which is first direct child:

# for only first direct child
soup.find("li", { "class" : "test" }).find("a", recursive=False)

If you want all direct children:

# for all direct children
soup.find("li", { "class" : "test" }).findAll("a", recursive=False)

select t.data_type 
  from user_tab_columns t 
 where t.TABLE_NAME = 'xxx' 
   and t.COLUMN_NAME='aaa'

You can modify with the following

<li><a href="./Index" class="elements"><span>Clients</span></a></li>

The extra dot means you are in the same controller. If you want change the controller to a different controller then you can write this

<li><a href="../newController/Index" class="elements"><span>Clients</span></a></li>

test.php

<?php  
return [
   'my_key_1'=>'1111111',
   'my_key_2'=>'2222222',
];

index.php

// Read array from file
$my_arr = include './test.php';

$my_arr["my_key_1"] = "3333333";

echo write_arr_to_file($my_arr, "./test.php");

/**
* @param array $arr <p>array</p>
* @param string $path <p>path to file</p>
* example :: "./test.php"
* @return bool <b>FALSE</b> occurred error
* more info: about "file_put_contents" https://www.php.net/manual/ru/function.file-put-contents.php
**/
function write_arr_to_file($arr, $path){
    $data = "\n";
    foreach ($arr as $key => $value) {
        $data = $data."   '".$key."'=>'".$value."',\n";
    }
    return file_put_contents($path, "<?php  \nreturn [".$data."];");
}

I have just discovered an alternative way of opening a new tab with the Router.

On your template,

<a (click)="openNewTab()" >page link</a>

And on your component.ts, you can use serializeUrl to convert the route into a string, which can be used with window.open()

openNewTab() {
  const url = this.router.serializeUrl(
    this.router.createUrlTree(['/example'])
  );

  window.open(url, '_blank');
}

You can use below code

IF (OBJECT_ID('TableName') IS NOT NULL )
BEGIN
  PRINT 'Table Exists'
END
ELSE
BEGIN 
  PRINT 'Table NOT Exists'
END

Or

IF (EXISTS (SELECT * FROM sys.tables WHERE [name] = 'TableName'))
BEGIN
  PRINT 'Table Exists'
END
ELSE
BEGIN 
  PRINT 'Table NOT Exists'
END

Laravel has a built-in method to shuffle the order of the results.

Here is a quote from the documentation:

shuffle()

The shuffle method randomly shuffles the items in the collection:

$collection = collect([1, 2, 3, 4, 5]);

$shuffled = $collection->shuffle();

$shuffled->all();

// [3, 2, 5, 1, 4] - (generated randomly)

You can see the documentation here.

Yes, you can use System.Reflection.Emit namespace for this. It is not straight forward if you have no experience with it, but it is certainly possible.

Edit: This code might be flawed, but it will give you the general idea and hopefully off to a good start towards the goal.

I needed to exclude an auditing @Aspect @Component from the app context but only for a few test classes. I ended up using @Profile("audit") on the aspect class; including the profile for normal operations but excluding it (don't put it in @ActiveProfiles) on the specific test classes.

nginx "fails fast" when the client informs it that it's going to send a body larger than the client_max_body_size by sending a 413 response and closing the connection.

Most clients don't read responses until the entire request body is sent. Because nginx closes the connection, the client sends data to the closed socket, causing a TCP RST.

If your HTTP client supports it, the best way to handle this is to send an Expect: 100-Continue header. Nginx supports this correctly as of 1.2.7, and will reply with a 413 Request Entity Too Large response rather than 100 Continue if Content-Length exceeds the maximum body size.

Replacement for Apple's Reachability re-written in Swift with closures, inspired by tonymillion: https://github.com/ashleymills/Reachability.swift

1. Drop the file Reachability.swift into your project. Alternatively, use CocoaPods or Carthage - See the Installation section of the project's README.

2. Get notifications about network connectivity:

   //declare this property where it won't go out of scope relative to your listener
   let reachability = Reachability()!
   
   reachability.whenReachable = { reachability in
       if reachability.isReachableViaWiFi {
           print("Reachable via WiFi")
       } else {
           print("Reachable via Cellular")
       }
   }
   
   reachability.whenUnreachable = { _ in
       print("Not reachable")
   }
   
   do {
       try reachability.startNotifier()
   } catch {
       print("Unable to start notifier")
   }
   

   and for stopping notifications

   reachability.stopNotifier()
   

Basically React.useState(0) magically sees that it should return the tuple count and setCount (a method to change count). The parameter useState takes sets the initial value of count.

  const [count, setCount] = React.useState(0);
  const [count2, setCount2] = React.useState(0);

  // increments count by 1 when first button clicked
  function handleClick(){
    setCount(count + 1);
  } 

  // increments count2 by 1 when second button clicked
  function handleClick2(){
    setCount2(count2 + 1);
  } 

  return (
    <div>
      <h2>A React counter made with the useState Hook!</h2>
      <p>You clicked {count} times</p>
      <p>You clicked {count2} times</p>
      <button onClick={handleClick}>
        Click me
      </button> 
      <button onClick={handleClick2}>
        Click me2
      </button>
  );

Based off Enmanuel Duran's example, but shows two counters and writes lambda functions as normal functions, so some people might understand it easier.

The standard C# convention, which works well enough in Java too, is to prefix all interfaces with an I - so your file handler interface will be IFileHandler and your truck interface will be ITruck. It's consistent, and makes it easy to tell interfaces from classes.

Leaving database modeling issues aside. I think you can try

SELECT * FROM STUDENTS WHERE ISNUMERIC(STUDENTID) = 0

But ISNUMERIC returns 1 for any value that seems numeric including things like -1.0e5

If you want to exclude digit-only studentids, try something like

SELECT * FROM STUDENTS WHERE STUDENTID LIKE '%[^0-9]%'

If you don't want to add a new dependency just to do this (like HTMLEntities) and you're already using Hpricot, it can both escape and unescape for you. It handles much more than CGI:

Hpricot.uxs "foo bär"
=> "foo bär"

if " isn't working then try " instead.

The function I used:

function cutAfter($string, $len = 30, $append = '...') {
        return (strlen($string) > $len) ? 
          substr($string, 0, $len - strlen($append)) . $append : 
          $string;
}

See it in action.

use checked : true, false property of the checkbox.

jQuery:

if($('input[type=checkbox]').is(':checked')) {
    $(this).prop('checked',true);
} else {
    $(this).prop('checked',false);
}

Script are executed sequentially only if they do not have either a "defer" or an "async" attribute. Knowing one of the possible ID/SRC/TITLE attributes of the script tag could work also in those cases. So both Greg and Justin suggestions are correct.

There is already a proposal for a document.currentScript on the WHATWG lists.

EDIT: Firefox > 4 already implement this very useful property but it is not available in IE11 last I checked and only available in Chrome 29 and Safari 8.

EDIT: Nobody mentioned the "document.scripts" collection but I believe that the following may be a good cross browser alternative to get the currently running script:

var me = document.scripts[document.scripts.length -1];

As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.

Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :

> x <- factor(sample(4:8,10,replace=T))
> x
 [1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
 [1] 6 4 8 6 7 6 8 5 8 4

To show it works.

The timings :

> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
   user  system elapsed 
   0.11    0.00    0.11 
> system.time(as.numeric(levels(x))[x])
   user  system elapsed 
      0       0       0 

It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.

You can use str_pad for adding 0's

str_pad($month, 2, '0', STR_PAD_LEFT); 

string str_pad ( string $input , int $pad_length [, string $pad_string = " " [, int $pad_type = STR_PAD_RIGHT ]] )

MAX_EXECUTION_TIME is also an important parameter for long running queries.Will work for MySQL 5.7 or later.

Check the current value

SELECT @@GLOBAL.MAX_EXECUTION_TIME, @@SESSION.MAX_EXECUTION_TIME;

Then set it according to your needs.

SET SESSION MAX_EXECUTION_TIME=2000;
SET GLOBAL MAX_EXECUTION_TIME=2000;

I would answer this with multiple options actually, the some of which actually render in the body.

• Place library script such as the jQuery library in the head section.
• Place normal script in the head unless it becomes a performance/page load issue.
• Place script associated with includes, within and at the end of that include. One example of this is .ascx user controls in asp.net pages - place the script at the end of that markup.
• Place script that impacts the render of the page at the end of the body (before the body closure).
• do NOT place script in the markup such as <input onclick="myfunction()"/> - better to put it in event handlers in your script body instead.
• If you cannot decide, put it in the head until you have a reason not to such as page blocking issues.

Footnote: "When you need it and not prior" applies to the last item when page blocking (perceptual loading speed). The user's perception is their reality—if it is perceived to load faster, it does load faster (even though stuff might still be occurring in code).

Side note: IF you place script blocks within markup, it may effect layout in certain browsers by taking up space (ie7 and opera 9.2 are known to have this issue) so place them in a hidden div (use a css class like: .hide { display: none; visibility: hidden; } on the div)

Standards: Note that the standards allow placement of the script blocks virtually anywhere if that is in question: http://www.w3.org/TR/1999/REC-html401-19991224/sgml/dtd.html and http://www.w3.org/TR/xhtml11/xhtml11_dtd.html

EDIT2: Note that whenever possible (always?) you should put the actual Javascript in external files and reference those - this does not change the pertinent sequence validity.

I ended up implementing my own adapter to wrap any other adapter and provide methods to add header and footer views.

Created a gist here: HeaderViewRecyclerAdapter.java

The main feature I wanted was a similar interface to a ListView, so I wanted to be able to inflate the views in my Fragment and add them to the RecyclerView in onCreateView. This is done by creating a HeaderViewRecyclerAdapter passing the adapter to be wrapped, and calling addHeaderView and addFooterView passing your inflated views. Then set the HeaderViewRecyclerAdapter instance as the adapter on the RecyclerView.

An extra requirement was that I needed to be able to easily swap out adapters while keeping the headers and footers, I didn't want to have multiple adapters with multiple instances of these headers and footers. So you can call setAdapter to change the wrapped adapter leaving the headers and footers intact, with the RecyclerView being notified of the change.

If these don't depend on the class or instance, then just make them a function.

As this would seem like the obvious solution. Unless of course you think it's going to need to be overwritten, subclassed, etc. If so, then the previous answers are the best bet. Fingers crossed I won't get marked down for merely offering an alternative solution that may or may not fit someone’s needs ;).

As the correct answer will depend on the use case of the code in question ;)

There is one way to achieve this that I did not see anybody mentioning here.

By rotating the parent container by 180 degrees and the child-container again by 180 degrees the scrollbar will be shown at top

.parent {
  transform: rotateX(180deg);
  overflow-x: auto;
} 
.child {
  transform: rotateX(180deg);
}

For reference see the issue in the w3c repository.

1. Download HAXM from the Intel site.

2. Install it.

3. And then run the AVD from AndroidStudio, menu -> Tools -> AVD. Choose x86.

It works!

I suggest to learn it with printf because for many cases this will be sufficient for your needs and you won't need to create other objects.

double d = 3.14159;     
printf ("%.2f", d);

But if you need rounding please refer to this post

Try this for Check Run-Time Permission:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    checkRunTimePermission();
}

Check run time permission:

private void checkRunTimePermission() {
    String[] permissionArrays = new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE};

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        requestPermissions(permissionArrays, 11111);
    } else {
         // if already permition granted
        // PUT YOUR ACTION (Like Open cemara etc..)
    }
}

Handle Permission result:

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    boolean openActivityOnce = true;
    boolean openDialogOnce = true;
    if (requestCode == 11111) {
        for (int i = 0; i < grantResults.length; i++) {
            String permission = permissions[i];

            isPermitted = grantResults[i] == PackageManager.PERMISSION_GRANTED;

            if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
                // user rejected the permission
                boolean showRationale = shouldShowRequestPermissionRationale(permission);
                if (!showRationale) {
                    //execute when 'never Ask Again' tick and permission dialog not show
                } else {
                    if (openDialogOnce) {
                        alertView();
                    }
                }
            }
        }

        if (isPermitted)
            if (isPermissionFromGallery)
                openGalleryFragment();
    }
}

Set custom alert:

private void alertView() {
    AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity(), R.style.MyAlertDialogStyle);

    dialog.setTitle("Permission Denied")
            .setInverseBackgroundForced(true)
            //.setIcon(R.drawable.ic_info_black_24dp)
            .setMessage("Without those permission the app is unable to save your profile. App needs to save profile image in your external storage and also need to get profile image from camera or external storage.Are you sure you want to deny this permission?")

            .setNegativeButton("I'M SURE", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialoginterface, int i) {
                    dialoginterface.dismiss();
                }
            })
            .setPositiveButton("RE-TRY", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialoginterface, int i) {
                    dialoginterface.dismiss();
                    checkRunTimePermission();

                }
            }).show();
}

It means you're trying to install an app with the same packageName as an app that's already installed on the emulator, but the one you're trying to install has a lower versionCode (integer value for your version number).

You might have installed from a separate copy of the code where the version number was higher than the copy you're working with right now. In either case, either:

• uninstall the currently installed copy

• or open up your phone's Settings > Application Manager to determine the version number for the installed app, and increment your <manifest android:versionCode to be higher in the AndroidManifest.

• or https://stackoverflow.com/a/13772620/632951

Try using the .frame modifier with the following options:

.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .topLeading)

struct ContentView: View {
    var body: some View {
        VStack(alignment: .leading) {
            Text("Hello World").font(.title)
            Text("Another").font(.body)
            Spacer()
        }.frame(minWidth: 0,
                maxWidth: .infinity,
                minHeight: 0,
                maxHeight: .infinity,
                alignment: .topLeading
        ).background(Color.red)
    }
}

This is described as being a flexible frame (see the documentation), which will stretch to fill the whole screen, and when it has extra space it will center its contents inside of it.

Try this:

ls -l  | awk -F : '{sum+=$5} END {print "AVG=",sum/NR}'

NR is an AWK builtin variable to count the no. of records

You can try any one of the following

1)Change the gradle.properties file and change the heap size as per your requirement.

If org.gradle.jvmargs=-Xmx2048M is not sufficient then change to 4096 as given

org.gradle.jvmargs=-Xmx4096M

2)"Edit Custom VM Options" from the Help menu.

It will open studio.vmoptions / studio64.exe.vmoptions file.

Change the content to

-Xms128m

-Xmx4096m

-XX:MaxPermSize=1024m

-XX:ReservedCodeCacheSize=200m

-XX:+UseCompressedOops

Save the the file and restart Android Studio.

You can use the drop_duplicates method to get the unique rows in a DataFrame:

In [29]: df = pd.DataFrame({'a':[1,2,1,2], 'b':[3,4,3,5]})

In [30]: df
Out[30]:
   a  b
0  1  3
1  2  4
2  1  3
3  2  5

In [32]: df.drop_duplicates()
Out[32]:
   a  b
0  1  3
1  2  4
3  2  5

You can also provide the subset keyword argument if you only want to use certain columns to determine uniqueness. See the docstring.

I know this is many years ago . But just for other people come across this topic. What you could do is to use getResourceAsStream() method with the directory path, and the input Stream will have all the files name from that dir. After that you can concat the dir path with each file name and call getResourceAsStream for each file in a loop.

Try this:

num = input("Please input your number: ")

num = float("%0.2f" % (num))

print(num)

I believe this is a lot simpler. For 1 decimal place use %0.1f. For 2 decimal places use %0.2f and so on.

Or, if you want to reduce it all to 2 lines:

num = float("%0.2f" % (float(input("Please input your number: "))))
print(num)

The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.

#!/bin/bash -vx

##config file with ip addresses like 10.10.10.1:80
file=config.txt

while read line ; do
  ##this line is not correct, should strip :port and store to ip var
  ip=$( echo "$line" |cut -d\: -f1 )
  ping $ip
done < ${file}

You could write your top line as

for line in $(cat $file) ; do ...

(but not recommended).

You needed command substitution $( ... ) to get the value assigned to $ip

reading lines from a file is usually considered more efficient with the while read line ... done < ${file} pattern.

I hope this helps.

For your particular case you could also use Array#join when constructing file path type of string:

string = [ROOT_DIR, project, 'App.config'].join('/')]

This has a pleasant side effect of automatically converting different types to string:

['foo', :bar, 1].join('/')
=>"foo/bar/1"

For infinite scrolling with days it's important you have the good fragment in the pager therefore I wrote my answer on this on page (Viewpager in Android to switch between days endlessly)

It's working very well! Above answers did not work for me as I wanted it to work.

0(logn)-Binary search, peak element in an array(there can be more than one peak) 0(1)-in python calculating the length of a list or a string. The len() function takes 0(1) time. Accessing an element in an array takes 0(1) time. Push operation in a stack takes 0(1) time. 0(nlogn)-Merge sort. sorting in python takes nlogn time. so when you use listname.sort() it takes nlogn time.

Note-Searching in a hash table sometimes takes more than constant time because of collisions.

Why don't you use a combination of HTML/CSS instead? Image maps are obsolete.

This btw is Search Engine Optimised as well :)

Source code follows:

.image-map {
  background: url('https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png');
  width: 272px;
  height: 92px;
  display: block;
  position: relative;
  margin-top:10px;
  float: left;
}

.image-map > a.map {
  position: absolute;
  display: block;
  border: 1px solid green;
}

<div class="image-map">
    <a class="map" rel="G" style="top: 0px; left: 0px; width: 70px; height: 95px;" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 70px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 120px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="g" style="top: 0px; left: 170px; width: 40px; height: 95px" href="#"></a>
    <a class="map" rel="l" style="top: 0px; left: 210px; width: 20px; height: 95px" href="#"></a>
    <a class="map" rel="e" style="top: 0px; left: 230px; width: 40px; height: 95px" href="#"></a>
</div>

EDIT:

After the numerous negative points this answer has received I have to come back and say that I can clearly see that you don't agree with my answer, but I personally still believe that is a better option than image maps.

Sure it cannot do polygons, it might have issues on manual page zoom, but personally I feel image maps are obsolete although still on the html5 specification. (It makes make more sense nowadays to try and replicate them using html5 canvas instead)

However I guess the target audience for this question does not agree with me.

You could also check this Are HTML Image Maps still used? and see the most highly voted answer just for reference.

In information technology it means that:

  f(n)=O(g(n)) If there is suitable constant C and N0 independent on N, 
  such that
  for all N>N0  "C*g(n) > f(n) > 0" is true.

Ant it seems that this notation was mostly have taken from mathematics.

In this article there is a quote: D.E. Knuth, "BIG OMICRON AND BIG OMEGA AND BIG THETA", 1976:

On the basis of the issues discussed here, I propose that members of SIGACT, and editors of computer science and mathematics journals, adopt notations as defined above, unless a better alternative can be found reasonably soon.

Today is 2016, but we use it still today.

In mathematical analysis it means that:

  lim (f(n)/g(n))=Constant; where n goes to +infinity

But even in mathematical analysis sometimes this symbol was used in meaning "C*g(n) > f(n) > 0".

As I know from university the symbol was intoduced by German mathematician Landau (1877-1938)

It's not just Visual Studio... It'd be any tools that read the files, compilers, linkers, etc. that would have to be able to handle it.

In general (for software development) we accept the multiplatform line ending issue, but let the version control software deal with it.

To populate ComboBox with JSON, you can consider using the: jqwidgets combobox, too.

Add disabled="disabled" in input and while jquery remove the attribute disabled when you want to submit it using .removeAttr('disabled')

HTML:

<input type="hidden" name="test" value="test" disabled='disabled'/>

jquery:

$("input[name='test']").removeAttr('disabled');

I have made a simple demo that prompts for X number of seconds and redirects to set url. If you don't want to wait until the end of the count, just click on the counter to redirect with no time. Simple counter that will count down while pulsing time in the midle of the page. You can run it onclick or while some page is loaded.

I also made github repo for this: https://github.com/GlupiJas/redirect-counter-plugin

JS CODE EXAMPLE:

// FUNCTION CODE
function gjCountAndRedirect(secounds, url)
{

        $('#gj-counter-num').text(secounds);

        $('#gj-counter-box').show();

    var interval = setInterval(function()
    {

        secounds = secounds - 1;

        $('#gj-counter-num').text(secounds);

        if(secounds == 0)
        {

            clearInterval(interval);
            window.location = url;
            $('#gj-counter-box').hide();

        }

    }, 1000);

    $('#gj-counter-box').click(function() //comment it out -if you dont want to allo count skipping
    {
        clearInterval(interval);
        window.location = url;

    });
}

// USE EXAMPLE
$(document).ready(function() {
    //var
    var gjCountAndRedirectStatus = false; //prevent from seting multiple Interval

    //call
    $('h1').click(function(){

        {
            gjCountAndRedirect(10, document.URL);
            gjCountAndRedirectStatus = true;
        }
    });

Swift 5+

In my case, I need to update the status bar hidden based on some conditions.

Because of this, I create a base controlller BaseViewController which contains new property hideStatusBar.

Other view controllers are sub-class of this base controller. Finally when I want to update the status bar behavior, I only need to change this hideStatusBar value.

class BaseViewController: UIViewController {

    var hideStatusBar: Bool = false {
        didSet {
            setNeedsStatusBarAppearanceUpdate()
        }
    }

    override var prefersStatusBarHidden: Bool {
           return hideStatusBar
    }
}

How to use

final class ViewController: BaseViewController, UIScrollViewDelegate {
    let scrollView = UIScrollView()

    ...

    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        UIView.animate(withDuration: 0.3) {
            if scrollView.contentOffset.y > 100 {
                self.hideStatusBar = true
            } else {
                self.hideStatusBar = false
            }
        }
    }
}

Demo

Here is a demo, I'm using UIView.animate(...) to make the transition smoother.

My Problem:

• I started a container with docker run <IMAGE_NAME>
• And then added some files to this container
• Then I closed the container and tried to start it again withe same command as above.
• But when I checked the new files, they were missing
• when I run docker ps -a I could see two containers.
• That means every time I was running docker run <IMAGE_NAME> command, new image was getting created

Solution: To work on the same container you created in the first place run follow these steps

• docker ps to get container of your container
• docker container start <CONTAINER_ID> to start existing container
• Then you can continue from where you left. e.g. docker exec -it <CONTAINER_ID> /bin/bash
• You can then decide to create a new image out of it

If you are working with objects track by the identifier(e.g. $index) instead of the whole object and you reload your data later, ngRepeat will not rebuild the DOM elements for items it has already rendered, even if the JavaScript objects in the collection have been substituted for new ones.

Quoting directly from the help page for factor:

To transform a factor f to its original numeric values, as.numeric(levels(f))[f] is recommended and slightly more efficient than as.numeric(as.character(f)).

It is possible to build an arbitrary GET or POST request and send it to any server accessible to a victims browser. This includes devices on your local network, such as Printers and Routers.

There are many ways of building a CSRF exploit. A simple POST based CSRF attack can be sent using .submit() method. More complex attacks, such as cross-site file upload CSRF attacks will exploit CORS use of the xhr.withCredentals behavior.

CSRF does not violate the Same-Origin Policy For JavaScript because the SOP is concerned with JavaScript reading the server's response to a clients request. CSRF attacks don't care about the response, they care about a side-effect, or state change produced by the request, such as adding an administrative user or executing arbitrary code on the server.

Make sure your requests are protected using one of the methods described in the OWASP CSRF Prevention Cheat Sheet. For more information about CSRF consult the OWASP page on CSRF.

Instead of using

response.sendRedirect("/demo.jsp");

Which does a permanent redirect to an absolute URL path,

Rather use RequestDispatcher. Example:

RequestDispatcher dispatcher = request.getRequestDispatcher("demo.jsp");
dispatcher.forward(request, response);

Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) Global comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public.

If your form is defined in your HTML, it is easier to pass the form into the constructor than it is to iterate and add images.

$('#my-form').submit( function(e) {
    e.preventDefault();

    var data = new FormData(this); // <-- 'this' is your form element

    $.ajax({
            url: '/my_URL/',
            data: data,
            cache: false,
            contentType: false,
            processData: false,
            type: 'POST',     
            success: function(data){
            ...

Try pysed:

pysed -r '# deb' 'deb' /etc/apt/sources.list

For me the problem was solved by restarting the docker daemon:

sudo systemctl restart docker

We can emulate a do-while loop in Bash with while [[condition]]; do true; done like this:

while [[ current_time <= $cutoff ]]
    check_if_file_present
    #do other stuff
do true; done

For an example. Here is my implementation on getting ssh connection in bash script:

#!/bin/bash
while [[ $STATUS != 0 ]]
    ssh-add -l &>/dev/null; STATUS="$?"
    if [[ $STATUS == 127 ]]; then echo "ssh not instaled" && exit 0;
    elif [[ $STATUS == 2 ]]; then echo "running ssh-agent.." && eval `ssh-agent` > /dev/null;
    elif [[ $STATUS == 1 ]]; then echo "get session identity.." && expect $HOME/agent &> /dev/null;
    else ssh-add -l && git submodule update --init --recursive --remote --merge && return 0; fi
do true; done

It will give the output in sequence as below:

Step #0 - "gcloud": intalling expect..
Step #0 - "gcloud": running ssh-agent..
Step #0 - "gcloud": get session identity..

Use like this:

when(
  fooDao.getBar(
    Matchers.<Bazoo>any()
  )
).thenReturn(myFoo);

Before you need to import Mockito.Matchers

Do we have java syntax corresponding to below process

HTTP and redirects

Let's first recap how ASP.NET MVC works:

1. When an HTTP request comes in, it is matched against a set of routes. If a route matches the request, the controller action corresponding to the route will be invoked.
2. Before invoking the action method, ASP.NET MVC performs model binding. Model binding is the process of mapping the content of the HTTP request, which is basically just text, to the strongly typed arguments of your action method

Let's also remind ourselves what a redirect is:

An HTTP redirect is a response that the webserver can send to the client, telling the client to look for the requested content under a different URL. The new URL is contained in a Location header that the webserver returns to the client. In ASP.NET MVC, you do an HTTP redirect by returning a RedirectResult from an action.

Passing data

If you were just passing simple values like strings and/or integers, you could pass them as query parameters in the URL in the Location header. This is what would happen if you used something like

return RedirectToAction("ActionName", "Controller", new { arg = updatedResultsDocument });

as others have suggested

The reason that this will not work is that the XDocument is a potentially very complex object. There is no straightforward way for the ASP.NET MVC framework to serialize the document into something that will fit in a URL and then model bind from the URL value back to your XDocument action parameter.

In general, passing the document to the client in order for the client to pass it back to the server on the next request, is a very brittle procedure: it would require all sorts of serialisation and deserialisation and all sorts of things could go wrong. If the document is large, it might also be a substantial waste of bandwidth and might severely impact the performance of your application.

Instead, what you want to do is keep the document around on the server and pass an identifier back to the client. The client then passes the identifier along with the next request and the server retrieves the document using this identifier.

Storing data for retrieval on the next request

So, the question now becomes, where does the server store the document in the meantime? Well, that is for you to decide and the best choice will depend upon your particular scenario. If this document needs to be available in the long run, you may want to store it on disk or in a database. If it contains only transient information, keeping it in the webserver's memory, in the ASP.NET cache or the Session (or TempData, which is more or less the same as the Session in the end) may be the right solution. Either way, you store the document under a key that will allow you to retrieve the document later:

int documentId = _myDocumentRepository.Save(updatedResultsDocument);

and then you return that key to the client:

return RedirectToAction("UpdateConfirmation", "ApplicationPoolController ", new { id = documentId });

When you want to retrieve the document, you simply fetch it based on the key:

 public ActionResult UpdateConfirmation(int id)
 {
      XDocument doc = _myDocumentRepository.GetById(id);

      ConfirmationModel model = new ConfirmationModel(doc);

      return View(model);
 }

This problem, in my case, wasn't related to the Insert key. It was related to Vrapper being enabled and editing like Vim, without my knowledge.

I just toggled the Vrapper Icon in Eclipse top bar of menus and then pressed the Insert Key and the problem was solved.

Hopefully this answer will help someone in the future.

First off, in a real application, you would never get database connection info in a servlet; you would configure it in your app server.

There are ways, however, of testing Servlets without having a container running. One is to use mock objects. Spring provides a set of very useful mocks for things like HttpServletRequest, HttpServletResponse, HttpServletSession, etc:

http://static.springsource.org/spring/docs/3.0.x/api/org/springframework/mock/web/package-summary.html

Using these mocks, you could test things like

What happens if username is not in the request?

What happens if username is in the request?

etc

You could then do stuff like:

import static org.junit.Assert.assertEquals;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.junit.Before;
import org.junit.Test;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;

public class MyServletTest {
    private MyServlet servlet;
    private MockHttpServletRequest request;
    private MockHttpServletResponse response;

    @Before
    public void setUp() {
        servlet = new MyServlet();
        request = new MockHttpServletRequest();
        response = new MockHttpServletResponse();
    }

    @Test
    public void correctUsernameInRequest() throws ServletException, IOException {
        request.addParameter("username", "scott");
        request.addParameter("password", "tiger");

        servlet.doPost(request, response);

        assertEquals("text/html", response.getContentType());

        // ... etc
    }
}

You can use the input Javascript event in jQuery like this:

$('#inputDatabaseName').on('input',function(e){
    alert('Changed!')
});

In pure JavaScript:

document.querySelector("input").addEventListener("change",function () {
  alert("Input Changed");
})

Or like this:

<input id="inputDatabaseName" onchange="youFunction();"
onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();"/>

I created a PS script to check idle time and jiggle the mouse to prevent the screensaver.

There are two parameters you can control how it works.

$checkIntervalInSeconds : the interval in seconds to check if the idle time exceeds the limit

$preventIdleLimitInSeconds : the idle time limit in seconds. If the idle time exceeds the idle time limit, jiggle the mouse to prevent the screensaver

Here we go. Save the script in preventIdle.ps1. For preventing the 4-min screensaver, I set $checkIntervalInSeconds = 30 and $preventIdleLimitInSeconds = 180.

I stole this from an XML document and it seems to cover all cases without the hard coded GIRO:

%r{[A-Z]{1,2}[0-9R][0-9A-Z]? [0-9][A-Z]{2}}i

(Ruby syntax with ignore case)

I just looked into my code. In one application, I just add the controls, but without specifying the index, and when done, I just loop through the row styles and set the size type to AutoSize. So just adding them without specifying the indices seems to add the rows as intended (provided the GrowStyle is set to AddRows).

In another application, I clear the controls and set the RowCount property to the needed value. This does not add the RowStyles. Then I add my controls, this time specifying the indices, and add a new RowStyle (RowStyles.Add(new RowStyle(...)) and this also works.

So, pick one of these methods, they both work. I remember the headaches the table layout panel caused me.

I've found three commands on how you can change your Git branch name, and these commands are a faster way to do that:

git branch -m old_branch new_branch         # Rename branch locally
git push origin :old_branch                 # Delete the old branch
git push --set-upstream origin new_branch   # Push the new branch, set local branch to track the new remote

If you need step-by-step you can read this great article:

How to Rename Git Local and Remote Branches

You could also use Restarter.

Restarter is an application that automatically monitor and restarts crashed or hung programs and applications. It was originally developed to monitor and restart game servers, but it will do the job for any console or form based program or application

I had this issue when i refereed a library project from a console application, and the library project was using a nuget package which is not refereed in the console application. Referring the same package in the console application helped to resolve this issue.

Seeing the Inner exception can help.

ngModel usually use for input tags for bind a variable that we can change variable from controller and html page but ngBind use for display a variable in html page and we can change variable just from controller and html just show variable.

You could also set onclick to call your function like this:

foo.onclick = function() { callYourJSFunction(arg1, arg2); };

This way, you can pass arguments too. .....

You can use -[UIButton setTitleColor:forState:] to do this.

Example:

Objective-C

[buttonName setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

Swift 2

buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)

Swift 3

buttonName.setTitleColor(UIColor.white, for: .normal)

Just be sure that you have include python to windows PATH variable, then run python -m ensurepip

If you like entering arcane operators from the command line, you’ll love these manual container backup techniques. Keep in mind, there’s a faster and more efficient way to backup containers that’s just as effective. I've written instructions here: https://www.morpheusdata.com/blog/2017-03-02-how-to-create-a-docker-backup-with-morpheus

Step 1: Add a Docker Host to Any Cloud As explained in a tutorial on the Morpheus support site, you can add a Docker host to the cloud of your choice in a matter of seconds. Start by choosing Infrastructure on the main Morpheus navigation bar. Select Hosts at the top of the Infrastructure window, and click the “+Container Hosts” button at the top right.

To back up a Docker host to a cloud via Morpheus, navigate to the Infrastructure screen and open the “+Container Hosts” menu.

Choose a container host type on the menu, select a group, and then enter data in the five fields: Name, Description, Visibility, Select a Cloud and Enter Tags (optional). Click Next, and then configure the host options by choosing a service plan. Note that the Volume, Memory, and CPU count fields will be visible only if the plan you select has custom options enabled.

Here is where you add and size volumes, set memory size and CPU count, and choose a network. You can also configure the OS username and password, the domain name, and the hostname, which by default is the container name you entered previously. Click Next, and then add any Automation Workflows (optional).Finally, review your settings and click Complete to save them.

Step 2: Add Docker Registry Integration to Public or Private Clouds Adam Hicks describes in another Morpheus tutorial how simple it is to integrate with a private Docker Registry. (No added configuration is required to use Morpheus to provision images with Docker’s public hub using the public Docker API.)

Select Integrations under the Admin tab of the main navigation bar, and then choose the “+New Integration” button on the right side of the screen. In the Integration window that appears, select Docker Repository in the Type drop-down menu, enter a name and add the private registry API endpoint. Supply a username and password for the registry you’re using, and click the Save Changes button.

Integrate a Docker Registry with a private cloud via the Morpheus “New Integration” dialog box.

To provision the integration you just created, choose Docker under Type in the Create Instance dialog, select the registry in the Docker Registry drop-down menu under the Configure tab, and then continue provisioning as you would any Docker container.

Step 3: Manage Backups Once you’ve added the Docker host and integrated the registry, a backup will be configured and performed automatically for each instance you provision. Morpheus support provides instructions for viewing backups, creating an instance backup, and creating a server backup.

var data=[{'com':'something'},{'com':'some other thing'}];
$.each(data, function() {
  $.each(this, function(key, val){
    alert(val);//here data 
      alert (key); //here key

  });
});

Expanding upon @aquinas:

Get-something | select -ExpandProperty PropertyName

or

Get-something | select -expand PropertyName

or

Get-something | select -exp PropertyName

I made these suggestions for those that might just be looking for a single-line command to obtain some piece of information and wanted to include a real-world example.

In managing Office 365 via PowerShell, here was an example I used to obtain all of the users/groups that had been added to the "BookInPolicy" list:

Get-CalendarProcessing [email protected] | Select -expand BookInPolicy

Just using "Select BookInPolicy" was cutting off several members, so thank you for this information!

Guava Documentation

The JDK provides Collections.unmodifiableXXX methods, but in our opinion, these can be unwieldy and verbose; unpleasant to use everywhere you want to make defensive copies unsafe: the returned collections are only truly immutable if nobody holds a reference to the original collection inefficient: the data structures still have all the overhead of mutable collections, including concurrent modification checks, extra space in hash tables, etc.

This class method can search in array by multiple conditions:

class Stdlib_Array
{
    public static function multiSearch(array $array, array $pairs)
    {
        $found = array();
        foreach ($array as $aKey => $aVal) {
            $coincidences = 0;
            foreach ($pairs as $pKey => $pVal) {
                if (array_key_exists($pKey, $aVal) && $aVal[$pKey] == $pVal) {
                    $coincidences++;
                }
            }
            if ($coincidences == count($pairs)) {
                $found[$aKey] = $aVal;
            }
        }

        return $found;
    }    
}

// Example:

$data = array(
    array('foo' => 'test4', 'bar' => 'baz'),
    array('foo' => 'test',  'bar' => 'baz'),
    array('foo' => 'test1', 'bar' => 'baz3'),
    array('foo' => 'test',  'bar' => 'baz'),
    array('foo' => 'test',  'bar' => 'baz4'),
    array('foo' => 'test4', 'bar' => 'baz1'),
    array('foo' => 'test',  'bar' => 'baz1'),
    array('foo' => 'test3', 'bar' => 'baz2'),
    array('foo' => 'test',  'bar' => 'baz'),
    array('foo' => 'test',  'bar' => 'baz'),
    array('foo' => 'test4', 'bar' => 'baz1')
);

$result = Stdlib_Array::multiSearch($data, array('foo' => 'test4', 'bar' => 'baz1'));

var_dump($result);

Will produce:

array(2) {
  [5]=>
  array(2) {
    ["foo"]=>
    string(5) "test4"
    ["bar"]=>
    string(4) "baz1"
  }
  [10]=>
  array(2) {
    ["foo"]=>
    string(5) "test4"
    ["bar"]=>
    string(4) "baz1"
  }
}

I faced the same problem and struggled for an hour to get pass through by reading the documents and the other issues reported in Stack Overflow but I didn't find any answer to it. So, here is the guide to successfully run the phonegap/cordova in Windows Machine.

Follow these steps

1. Download and Install node.js from http://nodejs.org/
2. Run the command npm install -g phonegap (in case of phonegap installation) or run the command npm install -g cordova (in case of Cordova installation).

3. As the installation gets completed you can notice this:

4. Notice the above line you can see the path were the file is mentioned. Copy that path. In my case it is C:\Users\binaryuser\AppData\Roaming\npm\cordova so use cd C:\Users\binaryuser\AppData\Roaming\npm\ and type cordova. There it is, it finally works.

5. Since the -g key value isn't working you have set the Environment Variables path:
   1. Press Win + Pause|Break or right click on Computer and choose Properties.
   2. Click Advanced system settings on the left.
   3. Click Environment Variables under the Advanced tab.
   4. Select the PATH variable and click Edit.
   5. Copy the path mentioned above to the value field and press OK.

SHA doesn't require anything but an input to be applied, while AES requires at least 3 things - what you're encrypting/decrypting, an encryption key, and the initialization vector.

Two-way binding just means that:

1. When properties in the model get updated, so does the UI.
2. When UI elements get updated, the changes get propagated back to the model.

Backbone doesn't have a "baked-in" implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding automagically.

In Backbone, you can easily achieve #1 by binding a view's "render" method to its model's "change" event. To achieve #2, you need to also add a change listener to the input element, and call model.set in the handler.

Here's a Fiddle with two-way binding set up in Backbone.

$json = json_encode($myObject);

// convert json => object

$json = json_encode($foo);
echo $json;

1- change the name of folder project

2- make a new project with the same project (before renaming)

3- add existing files from the old project to the new project (totally same , same folders , same names , ...)

4- open the the new project file (as xml ) and the old project

5- copy the new project file (xml content ) and paste it in the old project file

6- delete the old project

7- rename the old folder project to old name

Actually, technically when indented properly, it would be:

if (condition) {

} else {
    if (condition) {

There is no else if, strictly speaking.

You can use the react-moment package

Put in your file the next line:

import moment from "moment";

date_create: moment().format("DD-MM-YYYY hh:mm:ss")

You need to remove the

In my opinion should the alt text always describe what is visible in the picture, for the case that the image is not displayed.

alt = text [CS] For user agents that cannot display images, forms, or applets, this attribute specifies alternate text. The language of the alternate text is specified by the lang attribute.

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

os.walk can be used if you need recursion:

import os
start_path = '.' # current directory
for path,dirs,files in os.walk(start_path):
    for filename in files:
        print os.path.join(path,filename)

First of all, there are cases when object construction is a task complex enough to justify its extraction to another class.

I believe this point is incorrect. The complexity doesn't really matter. The relevance is what does. If an object can be constructed in one step (not like in the builder pattern), the constructor is the right place to do it. If you really need another class to perform the job, then it should be a helper class that is used from the constructor anyway.

Vec2(float x, float y);
Vec2(float angle, float magnitude); // not a valid overload!

There is an easy workaround for this:

struct Cartesian {
  inline Cartesian(float x, float y): x(x), y(y) {}
  float x, y;
};
struct Polar {
  inline Polar(float angle, float magnitude): angle(angle), magnitude(magnitude) {}
  float angle, magnitude;
};
Vec2(const Cartesian &cartesian);
Vec2(const Polar &polar);

The only disadvantage is that it looks a bit verbose:

Vec2 v2(Vec2::Cartesian(3.0f, 4.0f));

But the good thing is that you can immediately see what coordinate type you're using, and at the same time you don't have to worry about copying. If you want copying, and it's expensive (as proven by profiling, of course), you may wish to use something like Qt's shared classes to avoid copying overhead.

As for the allocation type, the main reason to use the factory pattern is usually polymorphism. Constructors can't be virtual, and even if they could, it wouldn't make much sense. When using static or stack allocation, you can't create objects in a polymorphic way because the compiler needs to know the exact size. So it works only with pointers and references. And returning a reference from a factory doesn't work too, because while an object technically can be deleted by reference, it could be rather confusing and bug-prone, see Is the practice of returning a C++ reference variable, evil? for example. So pointers are the only thing that's left, and that includes smart pointers too. In other words, factories are most useful when used with dynamic allocation, so you can do things like this:

class Abstract {
  public:
    virtual void do() = 0;
};

class Factory {
  public:
    Abstract *create();
};

Factory f;
Abstract *a = f.create();
a->do();

In other cases, factories just help to solve minor problems like those with overloads you have mentioned. It would be nice if it was possible to use them in a uniform way, but it doesn't hurt much that it is probably impossible.

I arrived at this page looking to turn off scale mode for good, so I figured I would share what I found:

It is possible using sun.misc.Unsafe : see this great answer from @Peter Lawrey -> Is there a way to get a reference address?

Using its code for printAddresses() :

    public static void printAddresses(String label, Object... objects) {
    System.out.print(label + ": 0x");
    long last = 0;
    int offset = unsafe.arrayBaseOffset(objects.getClass());
    int scale = unsafe.arrayIndexScale(objects.getClass());
    switch (scale) {
    case 4:
        long factor = is64bit ? 8 : 1;
        final long i1 = (unsafe.getInt(objects, offset) & 0xFFFFFFFFL) * factor;
        System.out.print(Long.toHexString(i1));
        last = i1;
        for (int i = 1; i < objects.length; i++) {
            final long i2 = (unsafe.getInt(objects, offset + i * 4) & 0xFFFFFFFFL) * factor;
            if (i2 > last)
                System.out.print(", +" + Long.toHexString(i2 - last));
            else
                System.out.print(", -" + Long.toHexString( last - i2));
            last = i2;
        }
        break;
    case 8:
        throw new AssertionError("Not supported");
    }
    System.out.println();
}

I set up this test :

    //hashcode
    System.out.println("Hashcode :       "+myObject.hashCode());
    System.out.println("Hashcode :       "+System.identityHashCode(myObject));
    System.out.println("Hashcode (HEX) : "+Integer.toHexString(myObject.hashCode()));

    //toString
    System.out.println("toString :       "+String.valueOf(myObject));

    printAddresses("Address", myObject);

Here is the output :

Hashcode :       125665513
Hashcode :       125665513
Hashcode (HEX) : 77d80e9
toString :       java.lang.Object@77d80e9
Address: 0x7aae62270

Conclusion :

• hashcode != address
• toString = class@HEX(hashcode)

Try to create a file using the code, so you will get to know the path of the file where the system create

I had the same problem on my virtual server with Parallels Plesk Panel 10.4.4. The solution was (thanks to Zappa for the idea) setting error_reporting value to 32767 instead of E_ALL.

I think your problem is that it's closing the document that calls the macro before sending the command to quit the application.

Your solution in that case is to not send a command to close the workbook. Instead, you could set the "Saved" state of the workbook to true, which would circumvent any messages about closing an unsaved book. Note: this does not save the workbook; it just makes it look like it's saved.

ThisWorkbook.Saved = True

and then, right after

Application.Quit

See Introducing XML Serialization:

Items That Can Be Serialized

The following items can be serialized using the XmlSerializer class:

• Public read/write properties and fields of public classes
• Classes that implement ICollection or IEnumerable
• XmlElement objects
• XmlNode objects
• DataSet objects

In particular, ISerializable or the [Serializable] attribute does not matter.

Now that you've told us what your problem is ("it doesn't work" is not a problem statement), you can get answers to your actual problem, instead of guesses.

When you serialize a collection of a type, but will actually be serializing a collection of instances of derived types, you need to let the serializer know which types you will actually be serializing. This is also true for collections of object.

You need to use the XmlSerializer(Type,Type[]) constructor to give the list of possible types.

I used this to extract a fasta sequence from a multi fasta file using the -P option for grep:

grep -Pzo ">tig00000034[^>]+"  file.fasta > desired_sequence.fasta

• P for perl based searches
• z for making a line end in 0 bytes rather than newline char
• o to just capture what matched since grep returns the whole line (which in this case since you did -z is the whole file).

The core of the regexp is the [^>] which translates to "not greater than symbol"

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

Essentially, use an <a> element with an href attr pointing to the phone number prefixed by tel:. Note that pluses can be used to specify country code, and hyphens can be included simply for human eyes.

MDN Web Docs

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#Creating_a_phone_link

The HTML <a> element (or anchor element), along with its href attribute, creates a hyperlink to other web pages, files, locations within the same page, email addresses, or any other URL.

Offering phone links is helpful for users viewing web documents and laptops connected to phones.

<a href="tel:+491570156">+49 157 0156</a>

The tel URI for Telephone Numbers

The "tel" URI has the following syntax:

telephone-uri = "tel:" telephone-subscriber

[…]

Examples

tel:+1-201-555-0123: This URI points to a phone number in the United States. The hyphens are included to make the number more human readable; they separate country, area code and subscriber number.

tel:7042;phone-context=example.com: The URI describes a local phone number valid within the context "example.com".

tel:863-1234;phone-context=+1-914-555: The URI describes a local phone number that is valid within a particular phone prefix.

Merging typed data structure trees is not trivial, you need to define the precedence, handle incompatible types, define how they will be casted and merged...

So in my opinion, you won't avoid

String.Format must start with zero index "{0}" like this:

Aboutme.Text = String.Format("{0}", reader.GetString(0));

Quick Answer

Use index_col=False instead of index_col=None when you have delimiters at the end of each line to turn off index column inference and discard the last column.

More Detail

After looking at the data, there is a comma at the end of each line. And this quote (the documentation has been edited since the time this post was created):

index_col: column number, column name, or list of column numbers/names, to use as the index (row labels) of the resulting DataFrame. By default, it will number the rows without using any column, unless there is one more data column than there are headers, in which case the first column is taken as the index.

from the documentation shows that pandas believes you have n headers and n+1 data columns and is treating the first column as the index.

EDIT 10/20/2014 - More information

I found another valuable entry that is specifically about trailing limiters and how to simply ignore them:

If a file has one more column of data than the number of column names, the first column will be used as the DataFrame’s row names: ...

Ordinarily, you can achieve this behavior using the index_col option.

There are some exception cases when a file has been prepared with delimiters at the end of each data line, confusing the parser. To explicitly disable the index column inference and discard the last column, pass index_col=False: ...

   ##### eg contain 2 list within a list. so if you want to use set() function
   you should flatten the list like [1, 2, 3, 4, 4, 5, 6, 7]

   >>> res= list(chain(*eg))       # [1, 2, 3, 4, 4, 5, 6, 7]                   
   >>> res1= set(res)                    #   [1, 2, 3, 4, 5, 6, 7]
   >>> res1= sorted(res1,reverse=True)

Then restart the server in eclipse.

You need some form of iteration here, as val (except when called with a function) only works on the first element:

$("input[placeholder]").val($("input[placeholder]").attr("placeholder"));

should be:

$("input[placeholder]").each( function () {
    $(this).val( $(this).attr("placeholder") );
});

or

$("input[placeholder]").val(function() {
    return $(this).attr("placeholder");
});

add this

owl.trigger('owl.play',6000);

You can take advantage of the head() (or first()) functions to see if the DataFrame has a single row. If so, it is not empty.

You can use StringBuilder:

    StringBuilder sb = new StringBuilder();
    sb.append('a');
    sb.append('b');
    sb.append('c');
    String str = sb.toString()

Or if you already have the characters, you can pass a character array to the String constructor:

String str = new String(new char[]{'a', 'b', 'c'});

ALTER IGNORE TABLE mytbl ADD UNIQUE (columnName);

1. Do not edit other files like httpd-xampp

2. Stop Apache

3. Open httpd-vhosts.conf located in **your_xampp_directory**\apache\conf\extra\ (your XAMPP directory might be by default: C:/xampp/htdocs)

4. Remove hash before the following line (aprox. line 20): NameVirtualHost *:80 (this might be optional)

5. Add the following virtual hosts at the end of the file, considering your directories paths:

   ##127.0.0.1
   <VirtualHost *:80>
       DocumentRoot "C:/xampp/htdocs"
       ServerName localhost

This confused the hell out of me - went through posts and posts suggesting ugly syspath hacks (as you see my __init__.py were all there). Well turns out that game/oblivion.py and game/oblivion was confusing python which spit out the rather unhelpful "No module named RecordGroups". I'd be interested in a workaround and/or links documenting this (same name) behavior -> EDIT (2017.01.24) - have a look at What If I Have a Module and a Package With The Same Name? Interestingly normally packages take precedence but apparently our launcher violates this.

EDIT (2015.01.17): I did not mention we use a custom launcher dissected here.

You have to specify the projectBaseDir if the module name doesn't match you module directory.

Since both your module are located in ".", you can simply add the following to your sonar-project properties:

module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.

Sonar will handle your modules as components of the project:

EDIT

If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions:

module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*

module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*
