This sample in VB.NET reads all extended properties:

Sub Main()
        Dim arrHeaders(35)

        Dim shell As New Shell32.Shell
        Dim objFolder As Shell32.Folder

        objFolder = shell.NameSpace("C:\tmp")

        For i = 0 To 34
            arrHeaders(i) = objFolder.GetDetailsOf(objFolder.Items, i)
        Next
        For Each strFileName In objfolder.Items
            For i = 0 To 34
                Console.WriteLine(i & vbTab & arrHeaders(i) & ": " & objfolder.GetDetailsOf(strFileName, i))
            Next
        Next

    End Sub

You have to add a reference to Microsoft Shell Controls and Automation from the COM tab of the References dialog.

Controller

ViewBag.hdnFlag= Session["hdnFlag"];

View

<input type="hidden" value="@ViewBag.hdnFlag" id="hdnFlag" />

JavaScript

var hdnFlagVal = $("#hdnFlag").val();

The correct way of doing this as of API 26 is described in the official documentation here :

https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml.html

This involves placing the ttf files in res/font folder and creating a font-family file.

a more generalized version of this... this will give you any day in the current week based on what day you specify.

//returns the relative day in the week 0 = Sunday, 1 = Monday ... 6 = Saturday
function getRelativeDayInWeek(d,dy) {
  d = new Date(d);
  var day = d.getDay(),
      diff = d.getDate() - day + (day == 0 ? -6:dy); // adjust when day is sunday
  return new Date(d.setDate(diff));
}

var monday = getRelativeDayInWeek(new Date(),1);
var friday = getRelativeDayInWeek(new Date(),5);

console.log(monday);
console.log(friday);

String value = "{first_name = naresh,last_name = kumar,gender = male}"

Let's start

1. Remove { and } from the String>>first_name = naresh,last_name = kumar,gender = male
2. Split the String from ,>> array of 3 element
3. Now you have an array with 3 element
4. Iterate the array and split each element by =
5. Create a Map<String,String> put each part separated by =. first part as Key and second part as Value

You can try the following regular expression:

\r?\n

Code:

String input = "\nab\n\n    \n\ncd\nef\n\n\n\n\n";
String[] lines = input.split("\\r?\\n", -1);
int n = 1;
for(String line : lines) {
    System.out.printf("\tLine %02d \"%s\"%n", n++, line);
}

Output:

Line 01 ""
Line 02 "ab"
Line 03 ""
Line 04 "    "
Line 05 ""
Line 06 "cd"
Line 07 "ef"
Line 08 ""
Line 09 ""
Line 10 ""
Line 11 ""
Line 12 ""

For one comparable

# Throws ValueError if nothing is found
some_list = ['foo', 'bar', 'baz'].index('baz')
# some_list == 2

Custom predicate

some_list = [item1, item2, item3]

# Throws StopIteration if nothing is found
# *unless* you provide a second parameter to `next`
index_of_value_you_like = next(
    i for i, item in enumerate(some_list)
    if item.matches_your_criteria())

Finding index of all items by predicate

index_of_staff_members = [
    i for i, user in enumerate(users)
    if user.is_staff()]

C++ does not have the for_each loop feature in its syntax. You have to use c++11 or use the template function std::for_each.

struct Function {
    int input;
    Function(int input): input(input) {}
    void operator()(Attack& attack) {
        if(attack->m_num == input) attack->makeDamage();
    }
};
Function f(input);
std::for_each(m_attack.begin(), m_attack.end(), f);

those are miliseconds, just divide them by 1000, since gmtime expects seconds ...

time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(1236472051807/1000.0))

This query works correct with composite keys also:

select c.constraint_name
    , x.table_schema as schema_name
    , x.table_name
    , x.column_name
    , y.table_schema as foreign_schema_name
    , y.table_name as foreign_table_name
    , y.column_name as foreign_column_name
from information_schema.referential_constraints c
join information_schema.key_column_usage x
    on x.constraint_name = c.constraint_name
join information_schema.key_column_usage y
    on y.ordinal_position = x.position_in_unique_constraint
    and y.constraint_name = c.unique_constraint_name
order by c.constraint_name, x.ordinal_position

You can easily change default remote for branches all at once simple using this command

git push -u <remote_name> --all

This fixed me

var width = window.innerWidth;
var height = window.innerHeight;

ECMAScript 2015 introduced destructuring assignment which works pretty nice:

[a, b] = [1, 2]

a will equal 1 and b will equal 2.

Here's a simpler (but not so short) version which doesn't require try-catch:

Map<String, String> data = new HashMap<>();
data.put("user", "[email protected]");
data.put("pass", "123");

JSONObject jsonData = new JSONObject(data);

If you want to add a jsonObject into a field, you can do this way:

data.put("socialMedia", (new JSONObject()).put("facebookId", "1174989895893400"));
data.put("socialMedia", (new JSONObject()).put("googleId", "106585039098745627377"));

Unfortunately it needs a try-catch because of the put() method.

IF you want to avoid try-catch again (not very recommended, but it's ok if you can guarantee well formated json strings), you might do this way:

data.put("socialMedia", "{ 'facebookId': '1174989895893400' }");

You can do the same about JsonArrays and so on.

Cheers.

ht editor can disassemble binaries in many formats. It is similar to Hiew, but open source.

To disassemble, open a binary, then press F6 and then select elf/image.

Icesoap, which I found yesterday, looks promising. It worked on a basic test, but it lacks more examples.

For those who are searching for a light answer, you can get a simple working example from here:

html {
    position: relative;
    min-height: 100%;
}
body {
    margin-bottom: 60px /* Height of the footer */
}
footer {
    position: absolute;
    bottom: 0;
    width: 100%;
    height: 60px /* Example value */
}

Just play with the body's margin-bottom for adding space between the content and footer.

As I noticed, log4net locks their output files the whole time application is running, so you can't delete them. Otherwise they are similar.

So I prefer NLog.

Create an XML file named border.xml in the drawable folder and put the following code in it.

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list> 

Then add a background to your linear layout like this:

         android:background="@drawable/border"

EDIT :

This XML was tested with a galaxy s running GingerBread 2.3.3 and ran perfectly as shown in image below:

ALSO

tested with galaxy s 3 running JellyBean 4.1.2 and ran perfectly as shown in image below :

Finally its works perfectly with all APIs

EDIT 2 :

It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:left="0dp" android:right="0dp"  android:top="0dp"  
        android:bottom="-10dp"> 
    <shape android:shape="rectangle">
     <stroke android:width="10dp" android:color="#B22222" />
    </shape>
   </item>  
 </layer-list> 

hope this help .

Time has moved on and since version 2 Ruby supports named parameters:

def ldap_get ( base_dn, filter, scope: "some_scope", attrs: nil )
  p attrs
end

ldap_get("first_arg", "second_arg", attrs: "attr1, attr2") # => "attr1, attr2"

You have to use querySelectorAll as you need to select all elements with the said class, again since querySelectorAll is an array you need to iterate it and add the event handlers

var deleteLinks = document.querySelectorAll('.delete');
for (var i = 0; i < deleteLinks.length; i++) {
    deleteLinks[i].addEventListener('click', function (event) {
        event.preventDefault();

        var choice = confirm("sure u want to delete?");
        if (choice) {
            return true;
        }
    });
}

Doesn't the Directory.GetFiles(String, String) overload already do that? You would just do Directory.GetFiles(dir, "*.jpg", SearchOption.AllDirectories)

If you want to put them in a list, then just replace the "*.jpg" with a variable that iterates over a list and aggregate the results into an overall result set. Much clearer than individually specifying them. =)

Something like...

foreach(String fileExtension in extensionList){
    foreach(String file in Directory.GetFiles(dir, fileExtension, SearchOption.AllDirectories)){
        allFiles.Add(file);
    }
}

(If your directories are large, using EnumerateFiles instead of GetFiles can potentially be more efficient)

I found we need to use noConflict sometimes:

jQuery.noConflict()(function ($) { // this was missing for me
    $(document).ready(function() { 

       other code here....

    });
});

From the docs:

Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. If you need to use another JavaScript library alongside jQuery, return control of $ back to the other library with a call to $.noConflict(). Old references of $ are saved during jQuery initialization; noConflict() simply restores them.

I just modified your code. It works fine in my system. See if this helps

class round{
    public static void main(String args[]){

    double a = 123.13698;
    double roundOff = Math.round(a*100)/100.00;

    System.out.println(roundOff);
}
}

You don't need HttpServletResponse to set a header on the response. You can do it using javax.ws.rs.core.Response. Just make your method to return Response instead of entity:

return Response.ok(entity).header("Content-Disposition", "attachment; filename=\"" + fileName + "\"").build()

If you still want to use HttpServletResponse you can get it either injected to one of the class fields, or using property, or to method parameter:

@Path("/resource")
class MyResource {

  // one way to get HttpServletResponse
  @Context
  private HttpServletResponse anotherServletResponse;

  // another way
  Response myMethod(@Context HttpServletResponse servletResponse) {
      // ... code
  }
}

You can use jQuery toggle to show and hide the div. The script will be like this

  <script type="text/javascript">
    jQuery(function(){
      jQuery("#music").click(function () {
        jQuery("#musicinfo").toggle("slow");
      });
    });
</script>

Use it in App Delegate: I am using storyboard

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {

    CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;

    //----------------HERE WE SETUP FOR IPHONE 4/4s/iPod----------------------

    if(iOSDeviceScreenSize.height == 480){          

        UIStoryboard *iPhone35Storyboard = [UIStoryboard storyboardWithName:@"iPhone" bundle:nil];

        // Instantiate the initial view controller object from the storyboard
        UIViewController *initialViewController = [iPhone35Storyboard instantiateInitialViewController];

        // Instantiate a UIWindow object and initialize it with the screen size of the iOS device
        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

        // Set the initial view controller to be the root view controller of the window object
        self.window.rootViewController  = initialViewController;

        // Set the window object to be the key window and show it
        [self.window makeKeyAndVisible];

        iphone=@"4";

        NSLog(@"iPhone 4: %f", iOSDeviceScreenSize.height);

    }

    //----------------HERE WE SETUP FOR IPHONE 5----------------------

    if(iOSDeviceScreenSize.height == 568){

        // Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone4
        UIStoryboard *iPhone4Storyboard = [UIStoryboard storyboardWithName:@"iPhone5" bundle:nil];

        // Instantiate the initial view controller object from the storyboard
        UIViewController *initialViewController = [iPhone4Storyboard instantiateInitialViewController];

        // Instantiate a UIWindow object and initialize it with the screen size of the iOS device
        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

        // Set the initial view controller to be the root view controller of the window object
        self.window.rootViewController  = initialViewController;

        // Set the window object to be the key window and show it
        [self.window makeKeyAndVisible];

         NSLog(@"iPhone 5: %f", iOSDeviceScreenSize.height);
        iphone=@"5";
    }

} else if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    // NSLog(@"wqweqe");
    storyboard = [UIStoryboard storyboardWithName:@"iPad" bundle:nil];

}

 return YES;
 }

No need for a regex here, if you just want to replace a piece of string by another: using str_replace() should be more than enough :

$new = str_replace(' ', '%20', $your_string);

But, if you want a bit more than that, and you probably do, if you are working with URLs, you should take a look at the urlencode() function.

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

Check out Joda, which simplifies date/time calculations (Joda is also the basis of the new standard Java date/time apis, so you'll be learning a soon-to-be-standard API).

EDIT: Java 8 has something very similar and is worth checking out.

e.g.

LocalDate birthdate = new LocalDate (1970, 1, 20);
LocalDate now = new LocalDate();
Years age = Years.yearsBetween(birthdate, now);

which is as simple as you could want. The pre-Java 8 stuff is (as you've identified) somewhat unintuitive.

Just change your syntax ever so slightly:

CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
     ELSE '"DECLINED"'
END

If you don't put the field expression before the CASE statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.

In windows version

you can find the log in the bottom of the IDE, click the "Gradle Console", and then choose the "Android Monitor". You will see a Droplistbox control which shows "Verbose" as a default value.

If you use log.v() . Verbose option is okay. if you use log.d(), just change it to Debug.

So when you run your emulator, you can catch your log from this window.

I want to add the important hint that converting a project like this can have side effects which are noticeable when you have a larger project. This is due the fact that Intellij Idea (2017) takes some important settings only from the pom.xml then which can lead to some confusion, following sections are affected at least:

1. Annotation settings are changed for the modules
2. Compiler output path is changed for the modules
3. Resources settings are ignored totally and only taken from pom.xml
4. Module dependencies are messed up and have to checked
5. Language/Encoding settings are changed for the modules

All these points need review and adjusting but after this it works like charm.

Further more unfortunately there is no sufficient pom.xml template created, I have added an example which might help to solve most problems.

Edit 2019:

• Added recursive resource scan
• Added directory specification which might be important to avoid confusion of IDEA recarding the content root structure

Just a quick note/summary for any who came here via Google looking for the answer to the general question asked in the title (as I was). Any of the following should work for getting access to shell variables inside quotes:

echo "$VARIABLE"
echo "${VARIABLE}"

Use of single quotes is the main issue. According to the Bash Reference Manual:

Enclosing characters in single quotes (') preserves the literal value of each character within the quotes. A single quote may not occur between single quotes, even when preceded by a backslash. [...] Enclosing characters in double quotes (") preserves the literal value of all characters within the quotes, with the exception of $, `, \, and, when history expansion is enabled, !. The characters $ and ` retain their special meaning within double quotes (see Shell Expansions). The backslash retains its special meaning only when followed by one of the following characters: $, `, ", \, or newline. Within double quotes, backslashes that are followed by one of these characters are removed. Backslashes preceding characters without a special meaning are left unmodified. A double quote may be quoted within double quotes by preceding it with a backslash. If enabled, history expansion will be performed unless an ! appearing in double quotes is escaped using a backslash. The backslash preceding the ! is not removed. The special parameters * and @ have special meaning when in double quotes (see Shell Parameter Expansion).

In the specific case asked in the question, $COLUMNS is a special variable which has nonstandard properties (see lhunath's answer above).

I simply write it this way

in the AspectType file:

class AspectType {
  //blah blah
}
module.exports = AspectType;

and import it like this:

const AspectType = require('./AspectType');
var aspectType = new AspectType;

you have to put this in web.config :

<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="50000000" />
      </webServices>
    </scripting>
  </system.web.extensions>

In simple terms, process.NextTick() would executed at next tick of event loop. However, the setImmediate, basically has a separate phase which ensures that the callback registered under setImmediate() will be called only after the IO callback and polling phase.

Please refer to this link for nice explanation: https://medium.com/the-node-js-collection/what-you-should-know-to-really-understand-the-node-js-event-loop-and-its-metrics-c4907b19da4c

This occurs when you specify the different name for repository table name and database table name. Please check your table name with database and repository.

No, there is no built in conversion for this. You'll need to create a constructor, like you mentioned, or some other conversion method.

Also, since BaseClass is not a DerivedClass, myDerivedObject will be null, andd the last line above will throw a null ref exception.

You also need to include the Log4J JAR file in the classpath.

Note that slf4j-log4j12-1.6.4.jar is only an adapter to make it possible to use Log4J via the SLF4J API. It does not contain the actual implementation of Log4J.

I found this here that describes how to set the VBA Project Password. You should be able to modify it to unset the VBA Project Password.

This one does not use SendKeys.

Let me know if this helps! JFV

It's like the COM registry done right, with respect to the physical files as well as their interface and location information. In COM, files were everywhere, with centralised metadata. The GAC centralises the bang shoot.

You can use generic code inspection via instanceof:

var e = document.getElementById('#my-element');
if (e instanceof HTMLInputElement) {}         // <input>
elseif (e instanceof HTMLSelectElement) {}    // <select>
elseif (e instanceof HTMLTextAreaElement) {}  // <textarea>
elseif (  ... ) {}                            // any interface

Look here for a complete list of interfaces.

edit: I guess it's now starting to be safe to use the native JSON.stringify() method, supported by most browsers (yes, even IE8+ if you're wondering).

As simple as:

JSON.stringify(yourData)

You should encode you data in JSON before sending it, you can't just send an object like this as POST data.

I recommand using the jQuery json plugin to do so. You can then use something like this in jQuery:

$.post(_saveDeviceUrl, {
    data : $.toJSON(postData)
}, function(response){
    //Process your response here
}
);

How can we read data from a text file and store in a String Variable?

Err, read data from the file and store it in a String variable. It's just code. Not a real question so far.

Is it possible to pass the filename in a method and it would return the String which is the text from the file.

Yes it's possible. It's also a very bad idea. You should deal with the file a part at a time, for example a line at a time. Reading the entire file into memory before you process any of it adds latency; wastes memory; and assumes that the entire file will fit into memory. One day it won't. You don't want to do it this way.

C is the core language that most closely resembles and directly translates into CPU machine code. CPUs follow instructions that move, add, logically combine, compare, jump, push and pop. C does exactly this using much easier syntax. If you study the disassembly, you can learn to write C code that is just as fast and compact as assembly. It is my preferred language on 8 bit micro controllers with limited memory. If you write a large PC program in C you will get into trouble because of its limited organization. That is where object oriented programming becomes powerful. The ability of C++ and C# classes to contain data and functions together enforces organization which in turn allows more complex operability over C. C++ was essential for quick processing in the past when CPUs only had one core. I am beginning to learn C# now. Its class only structure appears to enforce a higher degree of organization than C++ which should ultimately lead to faster development and promote code sharing. C# is not interpreted like VB. It is partially compiled at development time and then further translated at run time to become more platform friendly.

In my case by making build, from Build> Build apks, it worked.

        $http.get('http://dummy.com/app/chapter.php?user='+user+'&pass='+pass+'&sub='+sub)

            .then(function (response) {$scope.chapter = response.data.chp;});
           $scope.chapter = [];

};


}]);
    </script>

HTML:

<div ng-controller="dropdownCtrl">
<div ng-repeat="a in chapter">
<a href="topic.html?ch={{a.chapter}}" onClick="location.href=this.href+'&user='+user+'&pass='+pass+'&sub='+sub;return false;">{{a.chapter}}</a>
</div>

The problem is that variables declared in one case are still visible in the subsequent cases unless an explicit { } block is used, but they will not be initialized because the initialization code belongs to another case.

In the following code, if foo equals 1, everything is ok, but if it equals 2, we'll accidentally use the i variable which does exist but probably contains garbage.

switch(foo) {
  case 1:
    int i = 42; // i exists all the way to the end of the switch
    dostuff(i);
    break;
  case 2:
    dostuff(i*2); // i is *also* in scope here, but is not initialized!
}

Wrapping the case in an explicit block solves the problem:

switch(foo) {
  case 1:
    {
        int i = 42; // i only exists within the { }
        dostuff(i);
        break;
    }
  case 2:
    dostuff(123); // Now you cannot use i accidentally
}

Edit

To further elaborate, switch statements are just a particularly fancy kind of a goto. Here's an analoguous piece of code exhibiting the same issue but using a goto instead of a switch:

int main() {
    if(rand() % 2) // Toss a coin
        goto end;

    int i = 42;

  end:
    // We either skipped the declaration of i or not,
    // but either way the variable i exists here, because
    // variable scopes are resolved at compile time.
    // Whether the *initialization* code was run, though,
    // depends on whether rand returned 0 or 1.
    std::cout << i;
}

Below is Example of simple dropdown using jstl tag

 <form:select path="cityFrom">  
    <form:option value="Ghaziabad" label="Ghaziabad"/>  
    <form:option value="Modinagar" label="Modinagar"/>  
    <form:option value="Meerut" label="Meerut"/>  
    <form:option value="Amristar" label="Amristar"/>  
 </form:select>

Your tables should have as immediate children just tbody and thead elements, with the rows within*. So, amend the HTML to be:

<table border="1" width="100%" id="test">
  <tbody>
    <tr>
     <td>
      <table border="1" width="100%">
        <tbody>
          <tr>
            <td>table 2</td>
          </tr>
        </tbody>
      </table>
     </td>
    </tr> 
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
  </tbody>
</table>

Then amend your selector slightly to this:

#test > tbody > tr:last-child { background:#ff0000; }

See it in action here. That makes use of the child selector, which:

...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

So, you are targeting only direct children of tbody elements that are themselves direct children of your #test table.

Alternative solution

The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:

#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }

* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:

...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.

So this function gets rid of most of a specified listener type on an element:

function removeListenersFromElement(element, listenerType){
  const listeners = getEventListeners(element)[listenerType];
  let l = listeners.length;
  for(let i = l-1; i >=0; i--){
    removeEventListener(listenerType, listeners[i].listener);
  }
 }

There have been a few rare exceptions where one can't be removed for some reason.

This is the method that I would use.

DECLARE 
    @DateFrom DATETIME = GETDATE(),
    @DateTo DATETIME = DATEADD(HOUR, -1, GETDATE() + 2); -- Add 2 days and minus one hour


-- Dates spaced a day apart 

WITH MyDates (MyDate)
AS (
    SELECT @DateFrom
    UNION ALL
    SELECT DATEADD(DAY, 1, MyDate)
    FROM MyDates
    WHERE MyDate < @DateTo
   )

SELECT 
    MyDates.MyDate
    , CONVERT(DATE, MyDates.MyDate) AS [MyDate in DATE format]
FROM 
    MyDates;

Here is a similar example, but this time the dates are spaced one hour apart to further aid understanding of how the query works:

-- Alternative example with dates spaced an hour apart

WITH MyDates (MyDate)
AS (SELECT @DateFrom
    UNION ALL
    SELECT DATEADD(HOUR, 1, MyDate)
    FROM MyDates
    WHERE MyDate < @DateTo
   )

SELECT 
    MyDates.MyDate
FROM 
    MyDates;

As you can see, the query is fast, accurate and versatile.

The best answer is...

Don't use a regex

The expression in the accepted answer misses many cases. Among other things, URLs can have unicode characters in them. The regex you want is here, and after looking at it, you may conclude that you don't really want it after all. The most correct version is ten-thousand characters long.

Admittedly, if you were starting with plain, unstructured text with a bunch of URLs in it, then you might need that ten-thousand-character-long regex. But if your input is structured, use the structure. Your stated aim is to "extract the url, inside the anchor tag's href." Why use a ten-thousand-character-long regex when you can do something much simpler?

Parse the HTML instead

For many tasks, using Beautiful Soup will be far faster and easier to use:

>>> from bs4 import BeautifulSoup as Soup
>>> html = Soup(s, 'html.parser')           # Soup(s, 'lxml') if lxml is installed
>>> [a['href'] for a in html.find_all('a')]
['http://example.com', 'http://example2.com']

If you prefer not to use external tools, you can also directly use Python's own built-in HTML parsing library. Here's a really simple subclass of HTMLParser that does exactly what you want:

from html.parser import HTMLParser

class MyParser(HTMLParser):
    def __init__(self, output_list=None):
        HTMLParser.__init__(self)
        if output_list is None:
            self.output_list = []
        else:
            self.output_list = output_list
    def handle_starttag(self, tag, attrs):
        if tag == 'a':
            self.output_list.append(dict(attrs).get('href'))

Test:

>>> p = MyParser()
>>> p.feed(s)
>>> p.output_list
['http://example.com', 'http://example2.com']

You could even create a new method that accepts a string, calls feed, and returns output_list. This is a vastly more powerful and extensible way than regular expressions to extract information from html.

I was also facing the same problem for twitter-bootstrap.

As eternicode/bootstrap-datepicker is incompatible with jQuery UI.

But twitter-bootstrap is working fine for vitalets/bootstrap-datepicker even with jQuery UI.

Your code doesn't do what you might think it does. Async methods return immediately after the method begins waiting for the async result. It's insightful to use tracing in order to investigate how the code is actually behaving.

The code below does the following:

• Create 4 tasks
• Each task will asynchronously increment a number and return the incremented number
• When the async result has arrived it is traced.

static TypeHashes _type = new TypeHashes(typeof(Program));        
private void Run()
{
    TracerConfig.Reset("debugoutput");

    using (Tracer t = new Tracer(_type, "Run"))
    {
        for (int i = 0; i < 4; i++)
        {
            DoSomeThingAsync(i);
        }
    }
    Application.Run();  // Start window message pump to prevent termination
}


private async void DoSomeThingAsync(int i)
{
    using (Tracer t = new Tracer(_type, "DoSomeThingAsync"))
    {
        t.Info("Hi in DoSomething {0}",i);
        try
        {
            int result = await Calculate(i);
            t.Info("Got async result: {0}", result);
        }
        catch (ArgumentException ex)
        {
            t.Error("Got argument exception: {0}", ex);
        }
    }
}

Task<int> Calculate(int i)
{
    var t = new Task<int>(() =>
    {
        using (Tracer t2 = new Tracer(_type, "Calculate"))
        {
            if( i % 2 == 0 )
                throw new ArgumentException(String.Format("Even argument {0}", i));
            return i++;
        }
    });
    t.Start();
    return t;
}

You will notice that the Run method completes on thread 2820 while only one child thread has finished (2756). If you put a try/catch around your await method you can "catch" the exception in the usual way although your code is executed on another thread when the calculation task has finished and your contiuation is executed.

The calculation method traces the thrown exception automatically because I did use the ApiChange.Api.dll from the ApiChange tool. Tracing and Reflector helps a lot to understand what is going on. To get rid of threading you can create your own versions of GetAwaiter BeginAwait and EndAwait and wrap not a task but e.g. a Lazy and trace inside your own extension methods. Then you will get much better understanding what the compiler and what the TPL does.

Now you see that there is no way to get in a try/catch your exception back since there is no stack frame left for any exception to propagate from. Your code might be doing something totally different after you did initiate the async operations. It might call Thread.Sleep or even terminate. As long as there is one foreground thread left your application will happily continue to execute asynchronous tasks.

You can handle the exception inside the async method after your asynchronous operation did finish and call back into the UI thread. The recommended way to do this is with TaskScheduler.FromSynchronizationContext. That does only work if you have an UI thread and it is not very busy with other things.

Simply add class="img-responsive" to the video tag. I'm doing this on a current project, and it works. It doesn't need to be wrapped in anything.

<video class="img-responsive" src="file.mp4" autoplay loop/>

The following main steps are required to achieve a secured connection from Certification Authorities which are not considered as trusted by the android platform.

As requested by many users, I've mirrored the most important parts from my blog article here:

1. Grab all required certificates (root and any intermediate CA’s)
2. Create a keystore with keytool and the BouncyCastle provider and import the certs
3. Load the keystore in your android app and use it for the secured connections (I recommend to use the Apache HttpClient instead of the standard java.net.ssl.HttpsURLConnection (easier to understand, more performant)

Grab the certs

You have to obtain all certificates that build a chain from the endpoint certificate the whole way up to the Root CA. This means, any (if present) Intermediate CA certs and also the Root CA cert. You don’t need to obtain the endpoint certificate.

Create the keystore

Download the BouncyCastle Provider and store it to a known location. Also ensure that you can invoke the keytool command (usually located under the bin folder of your JRE installation).

Now import the obtained certs (don’t import the endpoint cert) into a BouncyCastle formatted keystore.

I didn’t test it, but I think the order of importing the certificates is important. This means, import the lowermost Intermediate CA certificate first and then all the way up to the Root CA certificate.

With the following command a new keystore (if not already present) with the password mysecret will be created and the Intermediate CA certificate will be imported. I also defined the BouncyCastle provider, where it can be found on my file system and the keystore format. Execute this command for each certificate in the chain.

keytool -importcert -v -trustcacerts -file "path_to_cert/interm_ca.cer" -alias IntermediateCA -keystore "res/raw/mykeystore.bks" -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath "path_to_bouncycastle/bcprov-jdk16-145.jar" -storetype BKS -storepass mysecret

Verify if the certificates were imported correctly into the keystore:

keytool -list -keystore "res/raw/mykeystore.bks" -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath "path_to_bouncycastle/bcprov-jdk16-145.jar" -storetype BKS -storepass mysecret

Should output the whole chain:

RootCA, 22.10.2010, trustedCertEntry, Thumbprint (MD5): 24:77:D9:A8:91:D1:3B:FA:88:2D:C2:FF:F8:CD:33:93
IntermediateCA, 22.10.2010, trustedCertEntry, Thumbprint (MD5): 98:0F:C3:F8:39:F7:D8:05:07:02:0D:E3:14:5B:29:43

Now you can copy the keystore as a raw resource in your android app under res/raw/

Use the keystore in your app

First of all we have to create a custom Apache HttpClient that uses our keystore for HTTPS connections:

import org.apache.http.*

public class MyHttpClient extends DefaultHttpClient {

    final Context context;

    public MyHttpClient(Context context) {
        this.context = context;
    }

    @Override
    protected ClientConnectionManager createClientConnectionManager() {
        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        // Register for port 443 our SSLSocketFactory with our keystore
        // to the ConnectionManager
        registry.register(new Scheme("https", newSslSocketFactory(), 443));
        return new SingleClientConnManager(getParams(), registry);
    }

    private SSLSocketFactory newSslSocketFactory() {
        try {
            // Get an instance of the Bouncy Castle KeyStore format
            KeyStore trusted = KeyStore.getInstance("BKS");
            // Get the raw resource, which contains the keystore with
            // your trusted certificates (root and any intermediate certs)
            InputStream in = context.getResources().openRawResource(R.raw.mykeystore);
            try {
                // Initialize the keystore with the provided trusted certificates
                // Also provide the password of the keystore
                trusted.load(in, "mysecret".toCharArray());
            } finally {
                in.close();
            }
            // Pass the keystore to the SSLSocketFactory. The factory is responsible
            // for the verification of the server certificate.
            SSLSocketFactory sf = new SSLSocketFactory(trusted);
            // Hostname verification from certificate
            // http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d4e506
            sf.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);
            return sf;
        } catch (Exception e) {
            throw new AssertionError(e);
        }
    }
}

We have created our custom HttpClient, now we can use it for secure connections. For example when we make a GET call to a REST resource:

// Instantiate the custom HttpClient
DefaultHttpClient client = new MyHttpClient(getApplicationContext());
HttpGet get = new HttpGet("https://www.mydomain.ch/rest/contacts/23");
// Execute the GET call and obtain the response
HttpResponse getResponse = client.execute(get);
HttpEntity responseEntity = getResponse.getEntity();

That's it ;)

You have invalid chars in your source. If you don't have any valid non ascii chars in your source, maybe in a double quoted string literal, you can simply convert your file back to ascii with:

tr -cd '\11\12\15\40-\176' < old.c > new.c

Edit: method with iconv will stop at wrong chars which makes no sense. The above command line is working with the example file. Good luck :-)

Write below code in script and also add jQuery library

var getElement = document.getElementById('myID');

if (document.activeElement === getElement) {
        $(document).keydown(function(event) {
            if (event.which === 40) {
                console.log('keydown pressed')
            }
        });
    }

Thank you...

Based on some answers above I came up with this type-safe function signature:

export function getStringValuesFromEnum<T>(myEnum: T): (keyof T)[] {
  return Object.keys(myEnum).filter(k => typeof (myEnum as any)[k] === 'number') as any;
}

Usage:

enum myEnum { entry1, entry2 };
const stringVals = getStringValuesFromEnum(myEnum);

the type of stringVals is 'entry1' | 'entry2'

Try this too in addition to MahmoudS comments. Change the maven compiler source and target in your pom.xml to the java version which you are using. Say 1.7 for jdk7

<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>

The situation on macOS is still a bit complicated, but do-able:

Python.org strongly suggest downloading tkinter from ActiveState, but you should read their license first (hint: don't redistribute or want Support).

When the download is opened OS X 10.11 rejected it because it couldn't find my receipt: "ActiveTcl-8.6.pkg can’t be opened because it is from an unidentified developer".

I followed an OSXDaily fix from 2012 which suggested allowing from anywhere. But OS X has now added an "Open Anyway" option to allow (e.g.) Active-Tcl as a once off, and the "Anywhere" option has gained a timeout.

What you show, ('A','B','C','D','E'), is not a list, it's a tuple (the round parentheses instead of square brackets show that). Nevertheless, whether it to index a list or a tuple (for getting one item at an index), in either case you append the index in square brackets.

So:

thetuple = ('A','B','C','D','E')
print thetuple[0]

prints A, and so forth.

Tuples (differently from lists) are immutable, so you couldn't assign to thetuple[0] etc (as you could assign to an indexing of a list). However you can definitely just access ("get") the item by indexing in either case.

Maybe something like this:

<script>
if(!window.jQuery)
{
   var script = document.createElement('script');
   script.type = "text/javascript";
   script.src = "path/to/jQuery";
   document.getElementsByTagName('head')[0].appendChild(script);
}
</script>

To update one column here are some syntax options:

Option 1

var ls=new int[]{2,3,4};
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>a.status=true);
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
     db.SomeTable
       .Where(x=>ls.Contains(x.friendid))
       .ToList()
       .ForEach(a=>a.status=true);

     db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
    }
    db.SubmitChanges();
}

Update

As requested in the comment it might make sense to show how to update multiple columns. So let's say for the purpose of this exercise that we want not just to update the status at ones. We want to update name and status where the friendid is matching. Here are some syntax options for that:

Option 1

var ls=new int[]{2,3,4};
var name="Foo";
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
    db.SomeTable
        .Where(x=>ls.Contains(x.friendid))
        .ToList()
        .ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
        some.name=name;
    }
    db.SubmitChanges();
}

Update 2

In the answer I was using LINQ to SQL and in that case to commit to the database the usage is:

db.SubmitChanges();

But for Entity Framework to commit the changes it is:

db.SaveChanges()

You can simply use take method and index of element (Last index can be -1).

arr = np.array([1,2,3])

last = arr.take(-1)
# 3

from the docs

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.

i applied the .navbar-text class to my <li> element, so the result is

<li class="nav-item navbar-text">

this centers the links vertically with respect to my navbar-brand img

string source = "/once/upon/a/time/";
int count = 0;
int n = 0;

while ((n = source.IndexOf('/', n)) != -1)
{
   n++;
   count++;
}

On my computer it's about 2 seconds faster than the for-every-character solution for 50 million iterations.

2013 revision:

Change the string to a char[] and iterate through that. Cuts a further second or two off the total time for 50m iterations!

char[] testchars = source.ToCharArray();
foreach (char c in testchars)
{
     if (c == '/')
         count++;
}

This is quicker still:

char[] testchars = source.ToCharArray();
int length = testchars.Length;
for (int n = 0; n < length; n++)
{
    if (testchars[n] == '/')
        count++;
}

For good measure, iterating from the end of the array to 0 seems to be the fastest, by about 5%.

int length = testchars.Length;
for (int n = length-1; n >= 0; n--)
{
    if (testchars[n] == '/')
        count++;
}

I was wondering why this could be and was Googling around (I recall something about reverse iterating being quicker), and came upon this SO question which annoyingly uses the string to char[] technique already. I think the reversal trick is new in this context, though.

What is the fastest way to iterate through individual characters in a string in C#?

It depends how long the function is. The longer the function, the greater the chance that someone modifying it in future will write data thinking that it means the global. In fact, it means the local, but because the function is so long, it's not obvious to them that there exists a local with that name.

For your example function, I think that shadowing the global is not bad at all.

From Java Tips: Difference between ear jar and war files:

These files are simply zipped files using the java jar tool. These files are created for different purposes. Here is the description of these files:

• .jar files: The .jar files contain libraries, resources and accessories files like property files.

• .war files: The war file contains the web application that can be deployed on any servlet/jsp container. The .war file contains jsp, html, javascript and other files necessary for the development of web applications.

Official Sun/Oracle descriptions:

• The J2EETM Tutorial: Web Application Archives
• The Java Archive (JAR) File Format: The Basics

Wikipedia articles:

• WAR file format (Sun)
• JAR file

It's very easy if you use Kotlin:

val textFile = File(cacheDir, "/text_file.txt")
val allText = textFile.readText()
println(allText)

From readText() docs:

Gets the entire content of this file as a String using UTF-8 or specified charset. This method is not recommended on huge files. It has an internal limitation of 2 GB file size.

Use this query:

UPDATE `table` SET date_date=now();

Sample code can be:

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

mysql_query("UPDATE `table` SET date_date=now()");

mysql_close($con);
?>

You need to use bindValue, not bindParam

bindParam takes a variable by reference, and doesn't pull in a value at the time of calling bindParam. I found this in a comment on the PHP docs:

bindValue(':param', null, PDO::PARAM_INT);

P.S. You may be tempted to do this bindValue(':param', null, PDO::PARAM_NULL); but it did not work for everybody (thank you Will Shaver for reporting.)

Simple way to solve

var day = document.getElementById("DayTextBox").value;

var regExp = /^([1-9]|[1][012])\/|-([1-9]|[1][0-9]|[2][0-9]|[3][01])\/|-([1][6-9][0-9][0-9]|[2][0][01][0-9])$/;

return regExp.test(day);

Another option that's pretty clean (No pun intended.):

git clean -ndX

Explanation:

$ git help clean

git-clean - Remove untracked files from the working tree
-n, --dry-run - Don't actually remove anything, just show what would be done.
-d - Remove untracked directories in addition to untracked files.
-X - Remove only files ignored by Git.

Note: This solution will not show ignored files that have already been removed.

I have an alternative suggestion. The problem I see with most of the common recommendation of firing a blur event is that it has unexpected side-effects. It's not always a good thing to remove a focus state unexpectedly.

Why not this instead?

<input type="number" onwheel="return false;" />

It's very simple and straight-forward, easy to implement, and no side-effects that I can think of.

[Try this solution it's simple] You can create a static variable in a Swift class then call it from any Objective-C class.

For linear solution, you can use Manacher's algorithm. There is another algorithm call Gusfield's Algorithm, and below is the code in java:

public class Solution {  
    char[] temp;   
    public int match(int a, int b,int len){   
        int i = 0;   
        while (a-i>=0 && b+i<len && temp[a-i] == temp[b+i]) i++;   
        return i;   
    }  

    public String longestPalindrome(String s) {  

        //This makes use of the assumption that the string has not more than 1000 characters.  
        temp=new char[1001*2];  
        int[] z=new int[1001 * 2];  
        int L=0, R=0;  
        int len=s.length();  

        for(int i=0;i<len*2+1;i++){  
            temp[i]='.';  
        }  

        for(int i=0;i<len;++i){  
            temp[i*2+1] = s.charAt(i);  
        }  

        z[0]=1;  
        len=len*2+1;  

        for(int i=0;i<len;i++){  
            int ii = L - (i - L);     
            int n = R + 1 - i;  
            if (i > R)  
            {  
                z[i] = match(i, i,len);  
                L = i;  
                R = i + z[i] - 1;  
            }  
            else if (z[ii] == n)  
            {  
                z[i] = n + match(i-n, i+n,len);  
                L = i;  
                R = i + z[i] - 1;  
            }  
            else  
            {  
                z[i] = (z[ii]<= n)? z[ii]:n;  
            }   
        }  

        int n = 0, p = 0;  
        for (int i=0; i<len; ++i)  
            if (z[i] > n)  
                n = z[p = i];  

        StringBuilder result=new StringBuilder();  
        for (int i=p-z[p]+1; i<=p+z[p]-1; ++i)  
            if(temp[i]!='.')  
                result.append(String.valueOf(temp[i]));  

        return result.toString();  
    }  
}  

You can find more on other solutions such as the best O(n^2) solution or Manacher's algorithm from my own blog.

Thanks, Valter Henrique, with your tip i managed to realise, that i simply entered incorrect path to this image. In one of my tries i use

    String pathToImageSortBy = "resources/testDataIcons/filling.png";
    ImageIcon SortByIcon = new ImageIcon(getClass().getClassLoader().getResource(pathToImageSortBy));

But correct way was use name of my project in path to resource

String pathToImageSortBy = "nameOfProject/resources/testDataIcons/filling.png";
ImageIcon SortByIcon = new ImageIcon(getClass().getClassLoader().getResource(pathToImageSortBy));

The difference between absolute and relative imports come into play only when you import a module from a package and that module imports an other submodule from that package. See the difference:

$ mkdir pkg
$ touch pkg/__init__.py
$ touch pkg/string.py
$ echo 'import string;print(string.ascii_uppercase)' > pkg/main1.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pkg/main1.py", line 1, in <module>
    import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
>>> 
$ echo 'from __future__ import absolute_import;import string;print(string.ascii_uppercase)' > pkg/main2.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 

In particular:

$ python2 pkg/main2.py
Traceback (most recent call last):
  File "pkg/main2.py", line 1, in <module>
    from __future__ import absolute_import;import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 
$ python2 -m pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ

Note that python2 pkg/main2.py has a different behaviour then launching python2 and then importing pkg.main2 (which is equivalent to using the -m switch).

If you ever want to run a submodule of a package always use the -m switch which prevents the interpreter for chaining the sys.path list and correctly handles the semantics of the submodule.

Also, I much prefer using explicit relative imports for package submodules since they provide more semantics and better error messages in case of failure.

The ChildActionOnly attribute ensures that an action method can be called only as a child method from within a view. An action method doesn’t need to have this attribute to be used as a child action, but we tend to use this attribute to prevent the action methods from being invoked as a result of a user request. Having defined an action method, we need to create what will be rendered when the action is invoked. Child actions are typically associated with partial views, although this is not compulsory.

1. [ChildActionOnly] allowing restricted access via code in View

2. State Information implementation for specific page URL. Example: Payment Page URL (paying only once) razor syntax allows to call specific actions conditional

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

As your data already in varchar, you have to convert it into date first:

select convert(varchar(10), cast(ts as date), 101) from <your table>

I Had the same issue earlier,removing Persist Security Info=True from connectionstring worked for me.

OS X / macOS / FreeBSD sed

The -i flag works differently on macOS sed than in GNU sed.

Here's the way to use it on macOS / OS X:

sed -i '' '8i\
8 This is Line 8' FILE

See man 1 sed for more info.

I've run into issues with Webclient.Downloadstring before. If you do, you can try this:

WebRequest request = WebRequest.Create("http://www.google.com");
WebResponse response = request.GetResponse();
Stream data = response.GetResponseStream();
string html = String.Empty;
using (StreamReader sr = new StreamReader(data))
{
    html = sr.ReadToEnd();
}

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

If you use Docker, you should read this file: https://github.com/cloudbees/jenkins-ci.org-docker/blob/master/plugins.sh

Example of a parent Dockerfile:

FROM jenkins

<name>:<version>
<name2>:<version2>

My own implementation of generic restTemplate call:

private <REQ, RES> RES queryRemoteService(String url, HttpMethod method, REQ req, Class reqClass) {
    RES result = null;
    try {
        long startMillis = System.currentTimeMillis();

        // Set the Content-Type header
        HttpHeaders requestHeaders = new HttpHeaders();
        requestHeaders.setContentType(new MediaType("application","json"));            

        // Set the request entity
        HttpEntity<REQ> requestEntity = new HttpEntity<>(req, requestHeaders);

        // Create a new RestTemplate instance
        RestTemplate restTemplate = new RestTemplate();

        // Add the Jackson and String message converters
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
        restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

        // Make the HTTP POST request, marshaling the request to JSON, and the response to a String
        ResponseEntity<RES> responseEntity = restTemplate.exchange(url, method, requestEntity, reqClass);
        result = responseEntity.getBody();
        long stopMillis = System.currentTimeMillis() - startMillis;

        Log.d(TAG, method + ":" + url + " took " + stopMillis + " ms");
    } catch (Exception e) {
         Log.e(TAG, e.getMessage());
    }
    return result;
}

To add some context, I'm consuming RESTful service with this, hence all requests and responses are wrapped into small POJO like this:

public class ValidateRequest {
  User user;
  User checkedUser;
  Vehicle vehicle;
}

and

public class UserResponse {
  User user;
  RequestResult requestResult;
}

Method which calls this is the following:

public User checkUser(User user, String checkedUserName) {
    String url = urlBuilder()
            .add(USER)
            .add(USER_CHECK)
            .build();

    ValidateRequest request = new ValidateRequest();
    request.setUser(user);
    request.setCheckedUser(new User(checkedUserName));

    UserResponse response = queryRemoteService(url, HttpMethod.POST, request, UserResponse.class);
    return response.getUser();
}

And yes, there's a List dto-s as well.

After some years with node, I can say that there are no conventions for the directory/file structure. However most (professional) express applications use a setup like:

/
  /bin - scripts, helpers, binaries
  /lib - your application
  /config - your configuration
  /public - your public files
  /test - your tests

An example which uses this setup is nodejs-starter.

I personally changed this setup to:

/
  /etc - contains configuration
  /app - front-end javascript files
    /config - loads config
    /models - loads models
  /bin - helper scripts
  /lib - back-end express files
    /config - loads config to app.settings
    /models - loads mongoose models
    /routes - sets up app.get('..')...
  /srv - contains public files
  /usr - contains templates
  /test - contains test files

In my opinion, the latter matches better with the Unix-style directory structure (whereas the former mixes this up a bit).

I also like this pattern to separate files:

lib/index.js

var http = require('http');
var express = require('express');

var app = express();

app.server = http.createServer(app);

require('./config')(app);

require('./models')(app);

require('./routes')(app);

app.server.listen(app.settings.port);

module.exports = app;

lib/static/index.js

var express = require('express');

module.exports = function(app) {

  app.use(express.static(app.settings.static.path));

};

This allows decoupling neatly all source code without having to bother dependencies. A really good solution for fighting nasty Javascript. A real-world example is nearby which uses this setup.

Update (filenames):

Regarding filenames most common are short, lowercase filenames. If your file can only be described with two words most JavaScript projects use an underscore as the delimiter.

Update (variables):

Regarding variables, the same "rules" apply as for filenames. Prototypes or classes, however, should use camelCase.

Update (styleguides):

• https://github.com/feross/standard
• https://github.com/airbnb/javascript

If you have something like:

<input type="checkbox" name="mycheckbox" value="11" checked="">
<input type="checkbox" name="mycheckbox" value="12">

You can read all like this:

jQuery("input[name='mycheckbox']").each(function() {
    console.log( this.value + ":" + this.checked );
});

The snippet:

jQuery("input[name='mycheckbox']").each(function() {_x000D_
  console.log( this.value + ":" + this.checked );_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="checkbox" name="mycheckbox" value="11" checked="">_x000D_
<input type="checkbox" name="mycheckbox" value="12">

You can use the forName method of Class:

Class cls = Class.forName(clsName);
Object obj = cls.newInstance();

As ben foster says you can return the Javascripts and it will redirect you to the desired page.

To load page in the current page:

return JavaScript("window.location = 'http://www.google.co.uk'");'

To load page in the new tab:

return JavaScript("window.open('http://www.google.co.uk')");

The following code describes a simple example using POST method.(How one can pass data by POST method)

Here, I describe how one can use of POST method.

1. Set post string with actual username and password.

NSString *post = [NSString stringWithFormat:@"Username=%@&Password=%@",@"username",@"password"]; 

2. Encode the post string using NSASCIIStringEncoding and also the post string you need to send in NSData format.

NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; 

You need to send the actual length of your data. Calculate the length of the post string.

NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]]; 

3. Create a Urlrequest with all the properties like HTTP method, http header field with length of the post string. Create URLRequest object and initialize it.

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 

Set the Url for which your going to send the data to that request.

[request setURL:[NSURL URLWithString:@"http://www.abcde.com/xyz/login.aspx"]]; 

Now, set HTTP method (POST or GET). Write this lines as it is in your code.

[request setHTTPMethod:@"POST"]; 

Set HTTP header field with length of the post data.

[request setValue:postLength forHTTPHeaderField:@"Content-Length"]; 

Also set the Encoded value for HTTP header Field.

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

Set the HTTPBody of the urlrequest with postData.

[request setHTTPBody:postData];

4. Now, create URLConnection object. Initialize it with the URLRequest.

NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 

It returns the initialized url connection and begins to load the data for the url request. You can check that whether you URL connection is done properly or not using just if/else statement as below.

if(conn) {
    NSLog(@"Connection Successful");
} else {
    NSLog(@"Connection could not be made");
}

5. To receive the data from the HTTP request , you can use the delegate methods provided by the URLConnection Class Reference. Delegate methods are as below.

// This method is used to receive the data which we get using post method.
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData*)data

// This method receives the error report in case of connection is not made to server. 
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error 

// This method is used to process the data after connection has made successfully.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection

Also Refer This and This documentation for POST method.

And here is best example with source code of HTTPPost Method.

Mathew's answer works for the terminal python shell, but it didn't work for IDLE shell in my case because many versions of python existed before I replaced them all with Python2.7.7. How I solved the problem with IDLE.

1. In terminal, cd /Applications/Python\ 2.7/IDLE.app/Contents/Resources/
2. then sudo nano idlemain.py, enter password if required.
3. after os.chdir(os.path.expanduser('~/Documents')) this line, I added sys.path.append("/Users/admin/Downloads....") NOTE: replace contents of the quotes with the directory where python module to be added
4. to save the change, ctrl+x and enter Now open idle and try to import the python module, no error for me!!!

Default JDK supports encryption only through 128 bit keys becuase of American restrictions. So to support encryption from 256 bit long key we have to replace local_policy.jar and US_export_policy.jars in $JAVA_HOME/java-8-oracle/jre/lib/security folder otherwise it will give:

java.security.InvalidKeyException: Illegal key size or default

You could also just copy plugins to the eclipse/plugins directory, but it's not recommended.

From mongodb.com:

NoSQL databases differ from older, relational technology in four main areas:

Data models: A NoSQL database lets you build an application without having to define the schema first unlike relational databases which make you define your schema before you can add any data to the system. No predefined schema makes NoSQL databases much easier to update as your data and requirements change.

Data structure: Relational databases were built in an era where data was fairly structured and clearly defined by their relationships. NoSQL databases are designed to handle unstructured data (e.g., texts, social media posts, video, email) which makes up much of the data that exists today.

Scaling: It’s much cheaper to scale a NoSQL database than a relational database because you can add capacity by scaling out over cheap, commodity servers. Relational databases, on the other hand, require a single server to host your entire database. To scale, you need to buy a bigger, more expensive server.

Development model: NoSQL databases are open source whereas relational databases typically are closed source with licensing fees baked into the use of their software. With NoSQL, you can get started on a project without any heavy investments in software fees upfront.

I followed around five different answers as well as all the blog posts in the previous answers and still had problems. I was trying to add a listener to some existing code that was tracing using the TraceSource.TraceEvent(TraceEventType, Int32, String) method where the TraceSource object was initialised with a string making it a 'named source'.

For me the issue was not creating a valid combination of source and switch elements to target this source. Here is an example that will log to a file called tracelog.txt. For the following code:

TraceSource source = new TraceSource("sourceName");
source.TraceEvent(TraceEventType.Verbose, 1, "Trace message");

I successfully managed to log with the following diagnostics configuration:

<system.diagnostics>
    <sources>
        <source name="sourceName" switchName="switchName">
            <listeners>
                <add
                    name="textWriterTraceListener"
                    type="System.Diagnostics.TextWriterTraceListener"
                    initializeData="tracelog.txt" />
            </listeners>
        </source>
    </sources>

    <switches>
        <add name="switchName" value="Verbose" />
    </switches>
</system.diagnostics>

I have never used jekyll, but it's main page says that it uses Liquid, and according to their docs, I think the following should work:

<ul> {% for page in site.pages %}     {% if page.title != 'index' %}     <li><div class="drvce"><a href="{{ page.url }}">{{ page.title }}</a></div></li>     {% endif %} {% endfor %} </ul> 

Replace

onclick="changeLink();"

by

onclick="changeLink(); return false;"

to cancel its default action

For exporting the instances of the classes you can use this syntax:

// export index.js
const Foo = require('./my/module/foo');
const Bar = require('./my/module/bar');

module.exports = {
    Foo : new Foo(),
    Bar : new Bar()
};

// import and run method
const {Foo,Bar} = require('module_name');
Foo.test();

If you don't really like nested functions, you can also iterate over the keys:

myMap : Map<string, boolean>;
for(let key of myMap) {
   if (myMap.hasOwnProperty(key)) {
       console.log(JSON.stringify({key: key, value: myMap[key]}));
   }
}

Note, you have to filter out the non-key iterations with the hasOwnProperty, if you don't do this, you get a warning or an error.

Yes you can use Boolean/boolean instead.

First one is Object and second one is primitive type.

• On first one, you will get more methods which will be useful.

• _{Second one is cheap considering memory expense} The second will save you a lot more memory, so go for it

Now choose your way.

As the others have already explained, the only difference is the precedence. However, I would like to point out that there are actually two differences between the two:

1. and, or and not have much lower precedence than &&, || and !
2. and and or have the same precedence, while && has higher precedence than ||

In general, it is good style to avoid the use of and, or and not and use &&, || and ! instead. (The Rails core developers, for example, reject patches which use the keyword forms instead of the operator forms.)

The reason why they exist at all, is not for boolean formulae but for control flow. They made their way into Ruby via Perl's well-known do_this or do_that idiom, where do_this returns false or nil if there is an error and only then is do_that executed instead. (Analogous, there is also the do_this and then_do_that idiom.)

Examples:

download_file_via_fast_connection or download_via_slow_connection
download_latest_currency_rates and store_them_in_the_cache

Sometimes, this can make control flow a little bit more fluent than using if or unless.

It's easy to see why in this case the operators have the "wrong" (i.e. identical) precedence: they never show up together in the same expression anyway. And when they do show up together, you generally want them to be evaluated simply left-to-right.

For me what worked was git checkout {SHA1 of commit with version to restore} "{path to file to restore}"

For example git checkout 5a6b3179e58edff9c90326b9a04284b02fd67bd0 "src-ui/views/includes/radar.pug"

(executed in the branch that we want the file to go into)

After that command executes, the restored file will exist in the original location (which will need to be comited)

As of 2018 and using ES6 modules and Promises, we can write a function like that :

import { get } from 'http';

export const fetch = (url) => new Promise((resolve, reject) => {
  get(url, (res) => {
    let data = '';
    res.on('end', () => resolve(data));
    res.on('data', (buf) => data += buf.toString());
  })
    .on('error', e => reject(e));
});

and then in another module

let data;
data = await fetch('http://www.example.com/api_1.php');
// do something with data...
data = await fetch('http://www.example.com/api_2.php');
// do something with data
data = await fetch('http://www.example.com/api_3.php');
// do something with data

The code needs to be executed in an asynchronous context (using async keyword)

I think, answers to this question are too old... currently some desktop and mobile browsers support HTML Templates for doing this.

I've built a little example:

Tested OK in Chrome 61.0, Opera 48.0, Opera Neon 1.0, Android Browser 6.0, Chrome Mobile 61.0 and Adblocker Browser 54.0
Tested KO in Safari 10.1, Firefox 56.0, Edge 38.14 and IE 11

This is working for me and really very helpful.

SubCategory.update({ _id: { $in:
        arrOfSubCategory.map(function (obj) {
            return mongoose.Types.ObjectId(obj);
        })
    } },
    {
        $pull: {
            coupon: couponId,
        }
    }, { multi: true }, function (err, numberAffected) {
        if(err) {
            return callback({
                error:err
            })
        }
    })
});

I have a model which name is SubCategory and I want to remove Coupon from this category Array. I have an array of categories so I have used arrOfSubCategory. So I fetch each array of object from this array with map function with the help of $in operator.

Use

Convert.toInt32(txtPrice.Text)

This is assuming VB.NET.

Judging by the name "txtPrice", you really don't want an Integer but a Decimal. So instead use:

Convert.toDecimal(txtPrice.Text)

If this is the case, be sure whatever you assign this to is Decimal not an Integer.

I have ran into that same problem. I actually developed my using server side programming, but I did a quick search to try and help you out and found this.

How about:

if('functionName' in Obj){
    //code
}

e.g.

var color1 = new String("green");
"length" in color1 // returns true
"indexOf" in color1 // returns true
"blablabla" in color1 // returns false

or as for your case:

if('onChange' in me){
    //code
}

Don't reinvent the wheel. C has sprintf for a reason. Since your variable is called score, I'm guessing this is for a game where you're planning to use the individual digits of the score to display the numeral glyphs as images. In this case, sprintf has convenient format modifiers that will let you zero-pad, space-pad, etc. the score to a fixed width, which you may want to use.

You have to placed this code in application.rb

config.action_dispatch.default_headers = {
        'Access-Control-Allow-Origin' => '*',
        'Access-Control-Request-Method' => %w{GET POST OPTIONS}.join(",")
}

Using Skip and Take is definitely the way to go. If I were implementing this, I would probably write my own extension method to handle paging (to make the code more readable). The implementation can of course use Skip and Take:

static class PagingUtils {
  public static IEnumerable<T> Page<T>(this IEnumerable<T> en, int pageSize, int page) {
    return en.Skip(page * pageSize).Take(pageSize);
  }
  public static IQueryable<T> Page<T>(this IQueryable<T> en, int pageSize, int page) {
    return en.Skip(page * pageSize).Take(pageSize);
  }
}

The class defines two extension methods - one for IEnumerable and one for IQueryable, which means that you can use it with both LINQ to Objects and LINQ to SQL (when writing database query, the compiler will pick the IQueryable version).

Depending on your paging requirements, you could also add some additional behavior (for example to handle negative pageSize or page value). Here is an example how you would use this extension method in your query:

var q = (from p in products
         where p.Show == true
         select new { p.Name }).Page(10, pageIndex);

Fixed! I basically just selected "Import" without even making a table myself. phpMyAdmin created the table for me, with all the right column names, from the original document.

As an alternative, Bintray provides free hosting of maven repositories. That's probably a good alternative to Sonatype OSS and Maven Central if you absolutely don't want to rename the groupId. But please, at least make an effort to get your changes integrated upstream or rename and publish to Central. It makes it much easier for others to use your fork.

Example. To find number of vowels within the string

var word='Web Development Tutorial';
var vowels='[aeiou]'; 
var re = new RegExp(vowels, 'gi');
var arr = word.match(re);
document.write(arr.length);

Here is an example to fully programmatically:

• init a Spinner.
• fill it with data via a String List.
• resize the Spinner and add it to my View.
• format the Spinner font (font size, colour, padding).
• clear the Spinner.
• add new values to the Spinner.
• redraw the Spinner.

I am using the following class vars:

Spinner varSpinner;
List<String> varSpinnerData;

float varScaleX;
float varScaleY;    

A - Init and render the Spinner (varRoot is a pointer to my main Activity):

public void renderSpinner() {


    List<String> myArraySpinner = new ArrayList<String>();

    myArraySpinner.add("red");
    myArraySpinner.add("green");
    myArraySpinner.add("blue");     

    varSpinnerData = myArraySpinner;

    Spinner mySpinner = new Spinner(varRoot);               

    varSpinner = mySpinner;

    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(varRoot, android.R.layout.simple_spinner_item, myArraySpinner);
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down vieww
    mySpinner.setAdapter(spinnerArrayAdapter);

B - Resize and Add the Spinner to my View:

    FrameLayout.LayoutParams myParamsLayout = new FrameLayout.LayoutParams(
            FrameLayout.LayoutParams.MATCH_PARENT, 
            FrameLayout.LayoutParams.WRAP_CONTENT);
    myParamsLayout.gravity = Gravity.NO_GRAVITY;             

    myParamsLayout.leftMargin = (int) (100 * varScaleX);
    myParamsLayout.topMargin = (int) (350 * varScaleY);             
    myParamsLayout.width = (int) (300 * varScaleX);;
    myParamsLayout.height = (int) (60 * varScaleY);;


    varLayoutECommerce_Dialogue.addView(mySpinner, myParamsLayout);

C - Make the Click handler and use this to set the font.

    mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int myPosition, long myID) {

            Log.i("renderSpinner -> ", "onItemSelected: " + myPosition + "/" + myID);

            ((TextView) parentView.getChildAt(0)).setTextColor(Color.GREEN);
            ((TextView) parentView.getChildAt(0)).setTextSize(TypedValue.COMPLEX_UNIT_PX, (int) (varScaleY * 22.0f) );
            ((TextView) parentView.getChildAt(0)).setPadding(1,1,1,1);


        }

        @Override
        public void onNothingSelected(AdapterView<?> parentView) {
            // your code here
        }

    });

}   

D - Update the Spinner with new data:

private void updateInitSpinners(){

     String mySelected = varSpinner.getSelectedItem().toString();
     Log.i("TPRenderECommerce_Dialogue -> ", "updateInitSpinners -> mySelected: " + mySelected);


     varSpinnerData.clear();

     varSpinnerData.add("Hello World");
     varSpinnerData.add("Hello World 2");

     ((BaseAdapter) varSpinner.getAdapter()).notifyDataSetChanged();
     varSpinner.invalidate();
     varSpinner.setSelection(1);

}

}

What I have not been able to solve in the updateInitSpinners, is to do varSpinner.setSelection(0); and have the custom font settings activated automatically.

UPDATE:

This "ugly" solution solves the varSpinner.setSelection(0); issue, but I am not very happy with it:

private void updateInitSpinners(){

    String mySelected = varSpinner.getSelectedItem().toString();
    Log.i("TPRenderECommerce_Dialogue -> ", "updateInitSpinners -> mySelected: " + mySelected);


    varSpinnerData.clear();

    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(varRoot, android.R.layout.simple_spinner_item, varSpinnerData);
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    varSpinner.setAdapter(spinnerArrayAdapter);  


    varSpinnerData.add("Hello World");
    varSpinnerData.add("Hello World 2");

    ((BaseAdapter) varSpinner.getAdapter()).notifyDataSetChanged();
    varSpinner.invalidate();
    varSpinner.setSelection(0);

}

}

Hope this helps......

Use-

<span ng-bind-html="myContent"></span>

You need to tell angular to not escape it.

A possible CSS ONLY solution can be achived with position: sticky;

The browser support is actually really good: https://caniuse.com/#search=position%3A%20sticky

here is an example: https://jsfiddle.net/0vcoa43L/7/

var str = "ff ff f f a de def";
str = str.replace(/f/g,'');
alert(str);

http://jsfiddle.net/ANHR9/

You can use with this format (tested on Laravel 5.5). In my case I used it for gettting the data of database connections and use on Controller:

$User = env('DB_USERNAMEchild','');
$Pass = env('DB_PASSWORDchild','');

The second parameter can be null, or set any default in case of DB_USERNAMEchild is null.

Your .env file can be the same:

DB_HOST=localhost
DB_DATABASE=FATHERBD
DB_USERNAME=root
DB_PASSWORD=password

DB_DATABASEchild=ZTEST
DB_USERNAMEchild=root
DB_PASSWORDchild=passwordofchild

import os

filename = C:\\Users\\Public\\Videos\\Sample Videos\\wildlife.wmv

This returns the filename without the extension(C:\Users\Public\Videos\Sample Videos\wildlife)

temp = os.path.splitext(filename)[0]  

Now you can get just the filename from the temp with

os.path.basename(temp)   #this returns just the filename (wildlife)

well, char * means a pointer point to char, it is different from char array.

char amessage[] = "this is an array";  /* define an array*/
char *pmessage = "this is a pointer"; /* define a pointer*/

And, char ** means a pointer point to a char pointer.

You can look some books about details about pointer and array.

I'm using this function based on @Murph answer. It searches inside the current directory and lists the full path:

function findit
{
$filename = $args[0];
gci -recurse -filter "*${filename}*" -file -ErrorAction SilentlyContinue | foreach-object {
    $place_path = $_.directory
    echo "${place_path}\${_}"
    }
}

Example usage: findit myfile

You should install IIS sub components from

Control Panel -> Programs and Features -> Turn Windows features on or off

Internet Information Services has subsection World Wide Web Services / Application Development Features

There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.

Run from cmd:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir

Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.

Also, look at this answer.

As stated in PostgreSQL docs here:

The SQL CASE expression is a generic conditional expression, similar to if/else statements in other programming languages.

Code snippet specifically answering your question:

SELECT field1, field2,
  CASE
    WHEN field1>0 THEN field2/field1
    ELSE 0
  END 
  AS field3
FROM test

This is really just a syntax switch. OK, so we have this method call:

[NSPredicate predicateWithFormat:@"name contains[c] %@", searchText];

In Swift, constructors skip the "blahWith…" part and just use the class name as a function and then go straight to the arguments, so [NSPredicate predicateWithFormat: …] would become NSPredicate(format: …). (For another example, [NSArray arrayWithObject: …] would become NSArray(object: …). This is a regular pattern in Swift.)

So now we just need to pass the arguments to the constructor. In Objective-C, NSString literals look like @"", but in Swift we just use quotation marks for strings. So that gives us:

let resultPredicate = NSPredicate(format: "name contains[c] %@", searchText)

And in fact that is exactly what we need here.

(Incidentally, you'll notice some of the other answers instead use a format string like "name contains[c] \(searchText)". That is not correct. That uses string interpolation, which is different from predicate formatting and will generally not work for this.)

What does

$ git config --get-regexp '^(remote|branch)\.'

returns (executed within your git repository) ?

Origin is just a default naming convention for referring to a remote Git repository.

If it does not refer to GitHub (but rather a path to your teammate repository, path which may no longer be valid or available), just add another origin, like in this Bloggitation entry

$ git remote add origin2 [email protected]:myLogin/myProject.git
$ git push origin2 master

(I would actually use the name 'github' rather than 'origin' or 'origin2')

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Check if your gitHub identity is correctly declared in your local Git repository, as mentioned in the GitHub Help guide. (both user.name and github.name -- and github.token)

Then, stonean blog suggests (as does Marcio Garcia):

$ cd ~/.ssh
$ ssh-add id_rsa

Aral Balkan adds: create a config file

The solution was to create a config file under ~/.ssh/ as outlined at the bottom of the OS X section of this page.

Here's the file I added, as per the instructions on the page, and my pushes started working again:

Host github.com
User git
Port 22
Hostname github.com
IdentityFile ~/.ssh/id_rsa
TCPKeepAlive yes
IdentitiesOnly yes

You can also post the result of

ssh -v [email protected]

to have more information as to why GitHub ssh connection rejects you.

Check also you did enter correctly your public key (it needs to end with '==').
Do not paste your private key, but your public one. A public key would look something like:

ssh-rsa AAAAB3<big string here>== [email protected] 

(Note: did you use a passphrase for your ssh keys ? It would be easier without a passphrase)

Check also the url used when pushing ([email protected]/..., not git://github.com/...)

Check that you do have a SSH Agent to use and cache your key.

Try this:

 $ ssh -i path/to/public/key [email protected]

If that works, then it means your key is not being sent to GitHub by your ssh client.

No need to apologize for asking a question! Try using the RIGHT function. It returns the last n characters of a string.

=RIGHT(A1, 1)

In one line, answer is as below;

[ CASE WHEN COLUMN_NAME = 'VALUE' THEN 'SHOW_THIS' ELSE 'SHOW_OTHER' END as ALIAS ]

I think it's local to the file you declared offset. Consider every file to be a method itself.

Maybe put the whole thing into a class and then make offset a class variable with @@offset = Point.new(100, 200);?

You should use dateutil. With that, you can use relativedelta, it's an improved version of timedelta.

>>> import datetime 
>>> import dateutil.relativedelta
>>> now = datetime.datetime.now()
>>> print now
2012-03-15 12:33:04.281248
>>> print now + dateutil.relativedelta.relativedelta(months=-1)
2012-02-15 12:33:04.281248

On my machine (Win10), the uninstaller was located at C:\ProgramData\Anaconda3\Uninstall-Anaconda3.exe.

This works for me:

ssh-add ~/.ssh/id_rsa

If you're just looking at values of cells you can store the values in an array of variant type. It seems that getting the value of an element in an array can be much faster than interacting with Excel, so you can see some difference in performance using an array of all cell values compared to repeatedly getting single cells.

Dim ValArray as Variant
ValArray = Range("A1:IV" & Rows.Count).Value

Then you can get a cell value just by checking ValArray( row , column )

An elaboration on Mundi's answer.

i.e. embedding a label in a UIView and enforcing padding through Auto Layout. Example:

Overview:

1) Create a UIView ("panel"), and set its appearance.

2) Create a UILabel and add it to the panel.

3) Add constraints to enforce padding.

4) Add the panel to your view hierarchy, then position the panel.

Details:

1) Create the panel view.

let panel = UIView()
panel.backgroundColor = .green
panel.layer.cornerRadius = 12

2) Create the label, add it to the panel as a subview.

let label = UILabel()
panel.addSubview(label)

3) Add constraints between the edges of the label and the panel. This forces the panel to keep a distance from the label. i.e. "padding"

Editorial: doing all this by hand is super-tedious, verbose and error-prone. I suggest you pick an Auto Layout wrapper from github or write one yourself

label.panel.translatesAutoresizingMaskIntoConstraints = false
label.topAnchor.constraint(equalTo: panel.topAnchor,
    constant: vPadding).isActive = true
label.bottomAnchor.constraint(equalTo: panel.bottomAnchor,
    constant: -vPadding).isActive = true
label.leadingAnchor.constraint(equalTo: panel.leadingAnchor,
    constant: hPadding).isActive = true
label.trailingAnchor.constraint(equalTo: panel.trailingAnchor,
    constant: -hPadding).isActive = true

label.textAlignment = .center

4) Add the panel to your view hierarchy and then add positioning constraints. e.g. hug the right-hand side of a tableViewCell, as in the example image.

Note: you only need to add positional constraints, not dimensional constraints: Auto Layout will solve the layout based on both the intrinsicContentSize of the label and the constraints added earlier.

hostView.addSubview(panel)
panel.translatesAutoresizingMaskIntoConstraints = false
panel.trailingAnchor.constraint(equalTo: hostView.trailingAnchor,
    constant: -16).isActive = true
panel.centerYAnchor.constraint(equalTo: hostView.centerYAnchor).isActive = true

No need to add commands anymore. For those who are new to Visual Studio Code and searching for an easy way to format code on saving, kindly follow the below steps.

1. Open Settings by pressing [Cmd+,] in Mac or using the below screenshot.

2. Type 'format' in the search box and enable the option 'Format On Save'.

You are done. Thank you.

Lea's converter is no longer available. I just used this converter

Steps:

1. Enter the Unicode decimal version such as 8226 in the tool's green input field.
2. Press Dec code points
3. See the result in the box Unicode U+hex notation (eg U+2022)
4. Use it in your CSS. Eg content: '\2022'

ps. I have no connection with the web site.

Most solutions work fine here. Would like to show another, similar alternative :

gradle:

implementation 'androidx.appcompat:appcompat:1.0.0-rc02'
implementation 'com.google.android.material:material:1.0.0-rc02'
implementation 'androidx.core:core-ktx:1.0.0-rc02'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

You layout can have a Toolbar View, and a shadow for it, below, similar to this (need modification of course) :

MainActivity.kt

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        setSupportActionBar(toolbar as Toolbar)
    }
}

Full sample here, as I've noticed the IDE has a bug of saying foreground attribute is too new to be used here.

Remove this from #info:

    margin-left:auto;

Add this for your header:

#info p {
    text-align: center;
}

Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align.

Sample
http://jsfiddle.net/Vc8CB/

1. Declare the variable
2. Set it by your command and add dynamic parts like use parameter values of sp(here @IsMonday and @IsTuesday are sp params)

3. execute the command

   declare  @sql varchar (100)
   set @sql ='select * from #td1'
   
   if (@IsMonday+@IsTuesday !='')
   begin
   set @sql= @sql+' where PickupDay in ('''+@IsMonday+''','''+@IsTuesday+''' )'
   end
   exec( @sql)
   

In addition mysql passwords when not using the IDENTIFIED BY clause, may be blank values, if non-blank, they may be encrypted. But yes USAGE is used to modify an account by granting simple resource limiters such as MAX_QUERIES_PER_HOUR, again this can be specified by also using the WITH clause, in conjuction with GRANT USAGE(no privileges added) or GRANT ALL, you can also specify GRANT USAGE at the global level, database level, table level,etc....

Here's something I quickly just made and it should perform far better than File.getName().endsWith(".xxxx");

import java.io.File;
import java.io.FileFilter;

public class ExtensionsFilter implements FileFilter 
{
    private char[][] extensions;

    private ExtensionsFilter(String[] extensions)
    {
        int length = extensions.length;
        this.extensions = new char[length][];
        for (String s : extensions)
        {
            this.extensions[--length] = s.toCharArray();
        }
    }

    @Override
    public boolean accept(File file)
    {
        char[] path = file.getPath().toCharArray();
        for (char[] extension : extensions)
        {
            if (extension.length > path.length)
            {
                continue;
            }
            int pStart = path.length - 1;
            int eStart = extension.length - 1;
            boolean success = true;
            for (int i = 0; i <= eStart; i++)
            {
                if ((path[pStart - i] | 0x20) != (extension[eStart - i] | 0x20))
                {
                    success = false;
                    break;
                }
            }
            if (success)
                return true;
        }
        return false;
    }
}

Here's an example for various images formats.

Because I have to reboot my VM regularly, so somehow this problem happens to me very often. After few times of it, I realized I cannot repeat the process described by @Nathan-Vanhoudnos every time this happens, though it always works. Then I figured out the following faster solution.

Step 1

Move your entire repo to another folder.

mv current_repo temp_repo

Step 2

Clone the repo from origin again.

git clone source_to_current_repo.git

Step 3

Remove Everything under the new repo except the .git folder.

Step 4

Move Everything from the temp_repo to the new repo except the .git folder.

Step 5

Remove the temp_repo, and we are done.

After few times, I'm sure you can do this procedures very quickly.

We were getting this same error in Fiddler when trying to figure out why our Silverlight ArcGIS map viewer wasn't loading the map. In our case it was a typo in the URL in the code. There was an equal sign in there for some reason.
http:=//someurltosome/awesome/place
instead of
http://someurltosome/awesome/place

After taking out that equal sign it worked great (of course).

I would suggest to watch model value and update it upon chage: http://plnkr.co/edit/Mb0uRyIIv1eK8nTg3Qng?p=preview

The only interesting issue is with spaces: In AngularJS 1.0.3 ng-model on input automatically trims string, so it does not detect that model was changed if you add spaces at the end or at start (so spaces are not automatically removed by my code). But in 1.1.1 there is 'ng-trim' directive that allows to disable this functionality (commit). So I've decided to use 1.1.1 to achieve exact functionality you described in your question.

I have combined some answers from the above thread and come up with the solution below. Although it is simple it can be used as a building block for making more complex key updates from a dictionary.

test_dict = {'a': 1, 'b': 2, 'c': 3}
print(test_dict)
# {'a': 1, 'b': 2, 'c': 3}
prefix = 'up'
def dict_key_update(json_file):    
    new_keys = []
    old_keys = []
    for i,(key,value) in enumerate(json_file.items()):
        old_keys.append(key)
        new_keys.append(str(prefix) + key) # i have updated by adding a prefix to the 
        # key
    for old_key, new_key in zip(old_keys,new_keys):
        print('old {}, new {}'.format(old_key, new_key))
        if new_key!=old_key:  
           json_file[new_key] = json_file.pop(old_key)
     return json_file

test_dict = dict_key_update(test_dict)
print(test_dict)
# {'upa': 1, 'upb': 2, 'upc': 3}

You may also use this

divID = "question-" + (i*1+1); 

to be sure that i is converted to integer.

You can concatenate strings using strcat. If you plan on concatenating numbers as strings, you must first use num2str to convert the numbers to strings.

Also, strings can't be stored in a vector or matrix, so f must be defined as a cell array, and must be indexed using { and } (instead of normal round brackets).

f = cell(N, 1);
for i=1:N
   f{i} = strcat('f', num2str(i));
end

If we encapsulate that in a function we could use recursion and state clearly the purpose by naming the function properly (not sure if getAny is actually a good name):

def getAny(dic, keys, default=None):
    return (keys or default) and dic.get(keys[0], 
                                         getAny( dic, keys[1:], default=default))

or even better, without recursion and more clear:

def getAny(dic, keys, default=None):
    for k in keys: 
        if k in dic:
           return dic[k]
    return default

Then that could be used in a way similar to the dict.get method, like:

getAny(myDict, keySet)

and even have a default result in case of no keys found at all:

getAny(myDict, keySet, "not found")

Use formaction attribute inside the button

PS! It only works if your button type="submit"

<button type="submit" formaction="www.youraddress.com">Submit</button>

tl;dr

The modern approach uses java.time classes.

Instant.now()                                        // Capture current moment in UTC.
       .truncatedTo( ChronoUnit.SECONDS )            // Lop off any fractional second.
       .plus( 8 , ChronoUnit.HOURS )                 // Add eight hours.
       .atZone( ZoneId.of( "America/Montreal" ) )    // Adjust from UTC to the wall-clock time used by the people of a certain region (a time zone). Returns a `ZonedDateTime` object.
       .format(                                      // Generate a `String` object representing textually the value of the `ZonedDateTime` object.
           DateTimeFormatter.ofPattern( "dd/MM/uuuu HH:mm:ss" )
                            .withLocale( Locale.US ) // Specify a `Locale` to determine the human language and cultural norms used in localizing the text being generated. 
       )                                             // Returns a `String` object.

java.time

FYI, the old Calendar and Date classes are now legacy. Supplanted by the java.time classes. Much of java.time is back-ported to Java 6, Java 7, and Android (see below).

Instant

Capture the current moment in UTC with the Instant class.

Instant instantNow = Instant.now();

instant.toString(): 2017-01-23T12:34:56.789Z

If you want only whole seconds, without any fraction of a second, truncate.

Instant instant = instantNow.truncatedTo( ChronoUnit.SECONDS );

instant.toString(): 2017-01-23T12:34:56Z

Math

The Instant class can do math, adding an amount of time. Specify the amount of time to add by the ChronoUnit enum, an implementation of TemporalUnit.

instant = instant.plus( 8 , ChronoUnit.HOURS );

instant.toString(): 2017-01-23T20:34:56Z

ZonedDateTime

To see that same moment through the lens of a particular region’s wall-clock time, apply a ZoneId to get a ZonedDateTime.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );

zdt.toString(): 2017-01-23T15:34:56-05:00[America/Montreal]

Generate string

You can generate a String in your desired format by specifying a formatting pattern in a DateTimeFormatter object.

Note that case matters in the letters of your formatting pattern. The Question’s code had hh which is for 12-hour time while uppercase HH is 24-hour time (0-23) in both java.time.DateTimeFormatter as well as the legacy java.text.SimpleDateFormat.

The formatting codes in java.time are similar to those in the legacy SimpleDateFormat but not exactly the same. Carefully study the class doc. Here, HH happens to work identically.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd/MM/uuuu HH:mm:ss" ).withLocale( Locale.US );
String output = zdt.format( f );

Automatic localization

Rather than hard-coding a formatting pattern, consider letting java.time fully localize the generation of the String text by calling DateTimeFormatter.ofLocalizedDateTime.

And, by the way, be aware that time zone and Locale have nothing to do with one another; orthogonal issues. One is about content, the meaning (the wall-clock time). The other is about presentation, determining the human language and cultural norms used in presenting that meaning to the user.

Instant instant = Instant.parse( "2017-01-23T12:34:56Z" );
ZoneId z = ZoneId.of( "Pacific/Auckland" );  // Notice that time zone is unrelated to the `Locale` used in localizing.
ZonedDateTime zdt = instant.atZone( z );

DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL )
                                       .withLocale( Locale.CANADA_FRENCH );  // The locale determines human language and cultural norms used in generating the text representing this date-time object.
String output = zdt.format( f );

instant.toString(): 2017-01-23T12:34:56Z

zdt.toString(): 2017-01-24T01:34:56+13:00[Pacific/Auckland]

output: mardi 24 janvier 2017 à 01:34:56 heure avancée de la Nouvelle-Zélande

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

Joda-Time

Update: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

Joda-Time makes this kind of work much easier.

// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;

DateTime later = DateTime.now().plusHours( 8 );
DateTimeFormatter formatter = DateTimeFormat.forPattern( "dd/MM/yyyy HH:mm:ss" );
String laterAsText = formatter.print( later );

System.out.println( "laterAsText: " + laterAsText );

When run…

laterAsText: 19/12/2013 02:50:18

Beware that this syntax uses default time zone. A better practice is to use an explicit DateTimeZone instance.

use this filter nav_menu_css_class as shown below

function add_classes_on_li($classes, $item, $args) {
    $classes[] = 'nav-item';
    return $classes;
}
add_filter('nav_menu_css_class','add_classes_on_li',1,3);

UPDATE

To use this filter with specific menu

if ( 'main-menu' === $args->theme_location ) { //replace main-menu with your menu
    $classes[] = "nav-item"; 
}

Some people recommend using HTTP status codes, but I rather despise that practice. e.g. If you're doing a search engine and the provided keywords have no results, the suggestion would be to return a 404 error.

However, I consider that wrong. HTTP status codes apply to the actual browser<->server connection. Everything about the connect went perfectly. The browser made a request, the server invoked your handler script. The script returned 'no rows'. Nothing in that signifies "404 page not found" - the page WAS found.

Instead, I favor divorcing the HTTP layer from the status of your server-side operations. Instead of simply returning some text in a json string, I always return a JSON data structure which encapsulates request status and request results.

e.g. in PHP you'd have

$results = array(
   'error' => false,
   'error_msg' => 'Everything A-OK',
   'data' => array(....results of request here ...)
);
echo json_encode($results);

Then in your client-side code you'd have

if (!data.error) {
   ... got data, do something with it ...
} else {
   ... invoke error handler ...
}

This is an online database but you can try with the stackoverflow database: https://data.stackexchange.com/stackoverflow/query/new

You also can download its dumps here:

Replace implementation with compile.

compile was recently deprecated and replaced by implementation or api

You first create the filter with fspecial and then convolve the image with the filter using imfilter (which works on multidimensional images as in the example).

You specify sigma and hsize in fspecial.

Code:

%%# Read an image
I = imread('peppers.png');
%# Create the gaussian filter with hsize = [5 5] and sigma = 2
G = fspecial('gaussian',[5 5],2);
%# Filter it
Ig = imfilter(I,G,'same');
%# Display
imshow(Ig)

I face same problem when install Scipy under ubuntu.
I had to use command:

$ sudo apt-get install libatlas-base-dev gfortran
$ sudo pip3 install scipy

Sorry don't know how to do it under OS X Yosemite.

Of course!

Use FirstOrDefault() to select the first object which matches the condition:

Answer answer = Answers.FirstOrDefault(a => a.Correct);

Otherwise use Where() to select a subset of your list:

var answers = Answers.Where(a => a.Correct);

localStorage is something that is kept on the client side. There is no data transmitted to the server side.

You can only get the data with JavaScript and you can send it to the server side with Ajax.

You can do this more easy way. And 100% works that you want

<?php
    $servername = "localhost";
    $username = "root";
    $password = "";  //your database password
    $dbname = "demo";  //your database name

    $con = new mysqli($servername, $username, $password, $dbname);

    if ($con->connect_error) {
        die("Connection failed: " . $con->connect_error);
    }
    else
    {
        //echo ("Connect Successfully");
    }
    $query = "SELECT Date_time, Tempout FROM alarm_value"; // select column
    $aresult = $con->query($query);

You are sending "params" in js: request.send(params);

but "data" in jquery". Is data defined?: data:data,

Also, you have an error in the URL:

$.ajax( {url:url,
         type:"POST",
         dataType:"json",
         data:data, 
         success:function(data, textStatus, jqXHR) {alert("success");},
         error: function(jqXHR, textStatus, errorThrown) {alert("failure");}
});

You are mixing the syntax with the one for $.post

Update: I was googling around based on monsur answer, and I found that you need to add Access-Control-Allow-Headers: Content-Type (below is the full paragraph)

http://metajack.im/2010/01/19/crossdomain-ajax-for-xmpp-http-binding-made-easy/

How CORS Works

CORS works very similarly to Flash's crossdomain.xml file. Basically, the browser will send a cross-domain request to a service, setting the HTTP header Origin to the requesting server. The service includes a few headers like Access-Control-Allow-Origin to indicate whether such a request is allowed.

For the BOSH connection managers, it is enough to specify that all origins are allowed, by setting the value of Access-Control-Allow-Origin to *. The Content-Type header must also be white-listed in the Access-Control-Allow-Headers header.

Finally, for certain types of requests, including BOSH connection manager requests, the permissions check will be pre-flighted. The browser will do an OPTIONS request and expect to get back some HTTP headers that indicate which origins are allowed, which methods are allowed, and how long this authorization will last. For example, here is what the Punjab and ejabberd patches I did return for OPTIONS:

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Headers: Content-Type 
Access-Control-Max-Age: 86400

Here is a DLL that shows:
* Hard drive ID (unique hardware serial number written in drive's IDE electronic chip)
* Partition ID (volume serial number)
* CPU ID (unique hardware ID)
* CPU vendor
* CPU running speed
* CPU theoretic speed
* Memory Load ( Total memory used in percentage (%) )
* Total Physical ( Total physical memory in bytes )
* Avail Physical ( Physical memory left in bytes )
* Total PageFile ( Total page file in bytes )
* Available PageFile( Page file left in bytes )

It works with C#.

You can directly export the query result with export option in the result grig. This export has various options to export. I think this will work.

The character 0x0C is be invalid in XML 1.0 but would be a valid character in XML 1.1. So unless the xml file specifies the version as 1.1 in the prolog it is simply invalid and you should complain to the producer of this file.

I had the same problem when using bootstrap-datewidget and i loaded jquery in the header instead of loading it at the end of the body and it worked.

To simplify Kirubaharan's answer a bit:

df['Datetime'] = pd.to_datetime(df['date'] + ' ' + df['time'])
df = df.set_index('Datetime')

And to get rid of unwanted columns (as OP did but did not specify per se in the question):

df = df.drop(['date','time'], axis=1)

If you want to reset every RowId via content provider try this

rowCounter=1;
do {            
            rowId = cursor.getInt(0);
            ContentValues values;
            values = new ContentValues();
            values.put(Table_Health.COLUMN_ID,
                       rowCounter);
            updateData2DB(context, values, rowId);
            rowCounter++;

        while (cursor.moveToNext());

public static void updateData2DB(Context context, ContentValues values, int rowId) {
    Uri uri;
    uri = Uri.parseContentProvider.CONTENT_URI_HEALTH + "/" + rowId);
    context.getContentResolver().update(uri, values, null, null);
}

These answers are no longer recommended since try_files works faster than if in this context. Simply add try_files in your php location block to test if the file exists, otherwise return a 404.

location ~ \.php {
    try_files $uri =404;
    ...
}

This code can distinguish between click and movement (drag, scroll). In onTouchEvent set a flag isOnClick, and initial X, Y coordinates on ACTION_DOWN. Clear the flag on ACTION_MOVE (minding that unintentional movement is often detected which can be solved with a THRESHOLD const).

private float mDownX;
private float mDownY;
private final float SCROLL_THRESHOLD = 10;
private boolean isOnClick;

@Override
public boolean onTouchEvent(MotionEvent ev) {
    switch (ev.getAction() & MotionEvent.ACTION_MASK) {
        case MotionEvent.ACTION_DOWN:
            mDownX = ev.getX();
            mDownY = ev.getY();
            isOnClick = true;
            break;
        case MotionEvent.ACTION_CANCEL:
        case MotionEvent.ACTION_UP:
            if (isOnClick) {
                Log.i(LOG_TAG, "onClick ");
                //TODO onClick code
            }
            break;
        case MotionEvent.ACTION_MOVE:
            if (isOnClick && (Math.abs(mDownX - ev.getX()) > SCROLL_THRESHOLD || Math.abs(mDownY - ev.getY()) > SCROLL_THRESHOLD)) {
                Log.i(LOG_TAG, "movement detected");
                isOnClick = false;
            }
            break;
        default:
            break;
    }
    return true;
}

For LongPress as suggested above, GestureDetector is the way to go. Check this Q&A:

Detecting a long press with Android

For SpringFramework Tests, I would recommend to add the below as well

org.springframework.test.web.servlet.request.MockMvcRequestBuilders
org.springframework.test.web.servlet.request.MockMvcResponseBuilders
org.springframework.test.web.servlet.result.MockMvcResultHandlers
org.springframework.test.web.servlet.result.MockMvcResultMatchers
org.springframework.test.web.servlet.setup.MockMvcBuilders
org.mockito.Mockito

When you add above as new Type it automatically add .* to the package.

Try to start the MySQL server:

mysql.server start

I find the answer. 1/First put in the presets, i have this example "Output format MPEG2 DVD HQ"

-vcodec mpeg2video -vstats_file MFRfile.txt -r 29.97 -s 352x480 -aspect 4:3 -b 4000k -mbd rd -trellis -mv0 -cmp 2 -subcmp 2 -acodec mp2 -ab 192k -ar 48000 -ac 2

If you want a report includes the commands -vstats_file MFRfile.txt into the presets like the example. this can make a report which it's ubicadet in the folder source of your file Source. you can put any name if you want , i solved my problem "i write many times in this forum" reading a complete .docx about mpeg properties. finally i can do my progress bar reading this txt file generated.

Regards.

You also have the Trim, TrimEnd and TrimStart methods of the System.String class. The trim method will strip whitespace (with a couple of Unicode quirks) from the leading and trailing portion of the string while allowing you to optionally specify the characters to remove.

#Note there are spaces at the beginning and end
Write-Host " ! This is a test string !%^ "
 ! This is a test string !%^
#Strips standard whitespace
Write-Host " ! This is a test string !%^ ".Trim()
! This is a test string !%^
#Strips the characters I specified
Write-Host " ! This is a test string !%^ ".Trim('!',' ')
This is a test string !%^
#Now removing ^ as well
Write-Host " ! This is a test string !%^ ".Trim('!',' ','^')
This is a test string !%
Write-Host " ! This is a test string !%^ ".Trim('!',' ','^','%')
This is a test string
#Powershell even casts strings to character arrays for you
Write-Host " ! This is a test string !%^ ".Trim('! ^%')
This is a test string

TrimStart and TrimEnd work the same way just only trimming the start or end of the string.

These posts may be in the wrong order! This is #2 in a series of 3 posts. Sorry.

I've "taken a few liberties" with Lie Ryan's code, implementing a linked list so individual elements of his vector can be accessed via a linked list. This allows access, but admittedly it is time-consuming to access individual elements due to search overhead, i.e. walking down the list until you find the right element. I'll cure this by maintaining an address vector containing subscripts 0 through whatever paired with memory addresses. This is still not as efficient as a plain-and-simple array would be, but at least you don't have to "walk the list" searching for the proper item.

The subset command is not necessary. Just use data frame indexing

studentdata[studentdata$Drink == 'water',]

Read the warning from ?subset

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like ‘[’, and in particular the non-standard evaluation of argument ‘subset’ can have unanticipated consequences.

I got the errors to go away by installing the Windows Universal CRT SDK component, which adds support for legacy Windows SDKs. You can install this using the Visual Studio Installer:

If the problem still persists, you should change the Target SDK in the Visual Studio Project : check whether the Windows SDK version is 10.0.15063.0.

In : Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0.

Then errno.h and other standard files will be found and it will compile.

Keep in mind that Windows has virtual memory management and the JVM only needs memory that is contiguous in its address space. So, other programs running on the system shouldn't necessarily impact your heap size. What will get in your way are DLL's that get loaded in to your address space. Unfortunately optimizations in Windows that minimize the relocation of DLL's during linking make it more likely you'll have a fragmented address space. Things that are likely to cut in to your address space aside from the usual stuff include security software, CBT software, spyware and other forms of malware. Likely causes of the variances are different security patches, C runtime versions, etc. Device drivers and other kernel bits have their own address space (the other 2GB of the 4GB 32-bit space).

You could try going through your DLL bindings in your JVM process and look at trying to rebase your DLL's in to a more compact address space. Not fun, but if you are desperate...

Alternatively, you can just switch to 64-bit Windows and a 64-bit JVM. Despite what others have suggested, while it will chew up more RAM, you will have much more contiguous virtual address space, and allocating 2GB contiguously would be trivial.

You can use alias to improve the query:

UPDATE t1
   SET t1.Value = t2.Value
  FROM table1 AS t1
         INNER JOIN 
       table2 AS t2
         ON t1.ID = t2.ID

Here is how I did it:
This was easier for me than trying to figure out the specific regex necessary.

int indexPictureData = result.IndexOf("-PictureData:");
int indexIdentity = result.IndexOf("-Identity:");
string returnValue = result.Remove(indexPictureData + 13);
returnValue = returnValue + " [bytecoderemoved] " + result.Remove(0, indexIdentity); `
