Quick and dirty method to determine if Maven is using desired settings.xml would be invalidate its xml and run some safe maven command that requires settings.xml.

If it reads this settings.xml then Maven reports an error: "Error reading settings.xml..."

The map file maps the unminified file to the minified file. If you make changes in the unminified file, the changes will be automatically reflected to the minified version of the file.

By specifying the option --user and --ask-password wget will ask for the credentials. Below is an example. Change the username and download link to your needs.

wget --user=username --ask-password https://xyz.com/changelog-6.40.txt

I think what has been under-emphasized in the cited answers is the issue of duplicates and problematic results that may arise from specific (use) cases.

(although Marcelo Cantos does mention it)

I will cite the example from Stanford's Lagunita courses on SQL.

Let's try to find the GPA scores for students that have applied to CS major (regardless of the university)

Using a subquery:

select GPA from Student where sID in (select sID from Apply where major = 'CS');

+------+
| GPA  |
+------+
|  3.9 |
|  3.5 |
|  3.7 |
|  3.9 |
|  3.4 |
+------+

The average value for this resultset is:

select avg(GPA) from Student where sID in (select sID from Apply where major = 'CS');

+--------------------+
| avg(GPA)           |
+--------------------+
| 3.6800000000000006 |
+--------------------+

Using a join:

select GPA from Student, Apply where Student.sID = Apply.sID and Apply.major = 'CS';

+------+
| GPA  |
+------+
|  3.9 |
|  3.9 |
|  3.5 |
|  3.7 |
|  3.7 |
|  3.9 |
|  3.4 |
+------+

average value for this resultset:

select avg(GPA) from Student, Apply where Student.sID = Apply.sID and Apply.major = 'CS';

+-------------------+
| avg(GPA)          |
+-------------------+
| 3.714285714285714 |
+-------------------+

It is obvious that the second attempt yields misleading results in our use case, given that it counts duplicates for the computation of the average value. It is also evident that usage of distinct with the join - based statement will not eliminate the problem, given that it will erroneously keep one out of three occurrences of the 3.9 score. The correct case is to account for TWO (2) occurrences of the 3.9 score given that we actually have TWO (2) students with that score that comply with our query criteria.

It seems that in some cases a sub-query is the safest way to go, besides any performance issues.

You do not need to insert the current timestamp manually as MySQL provides this facility to store it automatically. When the MySQL table is created, simply do this:

• select TIMESTAMP as your column type
• set the Default value to CURRENT_TIMESTAMP
• then just insert any rows into the table without inserting any values for the time column

You'll see the current timestamp is automatically inserted when you insert a row. Please see the attached picture.

Don't use height property in input field.

Example:

.heighttext{
    display:inline-block;
    padding:15px 10px;
    line-height:140%;
}

Always use padding and line-height css property. Its work perfect for all mobile device and all browser.

When the button is clicked, get the value of the input and use it to create an image element which is appended to the body (or anywhere else) :

<html>
<body>
<form>
    <input type="text" id="imagename" value="" />
    <input type="button" id="btn" value="GO" />
</form>
    <script type="text/javascript">
        document.getElementById('btn').onclick = function() {
            var val = document.getElementById('imagename').value,
                src = 'http://webpage.com/images/' + val +'.png',
                img = document.createElement('img');

            img.src = src;
            document.body.appendChild(img);
        }
    </script>
</body>
</html>

FIDDLE

the same in jQuery:

$('#btn').on('click', function() {
    var img = $('<img />', {src : 'http://webpage.com/images/' + $('#imagename').val() +'.png'});
    img.appendTo('body');
});

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
}
);

The following code works for me:

var data = [{"name":"Lenovo Thinkpad 41A4298","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41A2222","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41Awww33","website":"yahoo"},_x000D_
{"name":"Lenovo Thinkpad 41A424448","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41A429rr8","website":"ebay"},_x000D_
{"name":"Lenovo Thinkpad 41A429ff8","website":"ebay"},_x000D_
{"name":"Lenovo Thinkpad 41A429ss8","website":"rediff"},_x000D_
{"name":"Lenovo Thinkpad 41A429sg8","website":"yahoo"}]_x000D_
_x000D_
var data_filter = data.filter( element => element.website =="yahoo")_x000D_
console.log(data_filter)

No, you need to loop over the array

for(String s : strList) intList.add(Integer.valueOf(s));

why not just pass an data an object with your key/value pairs then you don't have to worry about encoding

$.ajax({
    type: "Post",
    url: "getdata.php",
    data:{
       timestamp: timestamp,
       uid: id,
       uname: name
    },
    async: true,
    cache: false,
    success: function(data) {


    };
}?);?

I put together a batch file for automatic enabling and connecting ADB via TCP, to a device connected via USB. With it you don't have to put in the IP manually.

@echo off
setlocal

REM Use a default env variable to find adb if possible
if NOT "%AndroidSDK%" == "" set PATH=%PATH%;%AndroidSDK%\platform-tools

REM If off is first parameter then we turn off the tcp connection.
if "%1%" == "off" goto off

REM Set vars
set port=%1
set int=%2
if "%port%" == "" set port=5557
if "%int%" == "" set int=wlan0

REM Enable TCP
adb -d wait-for-device tcpip %port%

REM Get IP Address from device
set shellCmd="ip addr show %int% | grep 'inet [0-9]{1,3}(\.[0-9]{1,3}){3}' -oE | grep '[0-9]{1,3}(\.[0-9]{1,3}){3}' -oE"
for /f %%i in ('adb wait-for-device shell %shellCmd%') do set IP=%%i

REM Connect ADB to device
adb connect %IP%:%port%

goto end

:fail
echo adbWifi [port] [interface]
echo adbWifi off
goto end

:off
adb wait-for-device usb

:end

Here I have added code, the way you want line by line.

The .= helps you to echo multiple lines of code.

$html = '<div>';
$html .= '<h3><a href="#">First</a></h3>';
$html .= '<div>Lorem ipsum dolor sit amet.</div>';
$html .= '</div>';
$html .= '<div>';
echo $html;

Combining what everyone said, I propose the following, to keep the list of characters special to RegExp clearly listed in their own String, and to avoid having to try to visually parse thousands of "\\"'s. This seems to work pretty well for me:

final String regExSpecialChars = "<([{\\^-=$!|]})?*+.>";
final String regExSpecialCharsRE = regExSpecialChars.replaceAll( ".", "\\\\$0");
final Pattern reCharsREP = Pattern.compile( "[" + regExSpecialCharsRE + "]");

String quoteRegExSpecialChars( String s)
{
    Matcher m = reCharsREP.matcher( s);
    return m.replaceAll( "\\\\$0");
}

The ErrorDocument directive, when supplied a local URL path, expects the path to be fully qualified from the DocumentRoot. In your case, this means that the actual path to the ErrorDocument is

ErrorDocument 404 /hellothere/error/404page.html

False, Null, Nothing, 0, Undefined, etc., etc.

Each of these has specific meanings that correlate with actual concepts. Sometimes multiple meanings are overloaded into a single keyword or value.

In C and C++, NULL, False and 0 are overloaded to the same value. In C# they're 3 distinct concepts.

null or NULL usually indicates a lack of value, but usually doesn't specify why. 0 indicates the natural number zero and has type-equivalence to 1, 2, 3, etc. and in languages that support separate concepts of NULL should be treated only a number.

False indicates non-truth. And it used in binary values. It doesn't mean unset, nor does it mean 0. It simply indicates one of two binary values.

Nothing can indicate that the value is specifically set to be nothing which indicates the same thing as null, but with intent.

Undefined in some languages indicates that the value has yet to be set because no code has specified an actual value.

awk -v sep=. 'BEGIN{ORS=OFS="";for(i=1;i<ARGC;i++){print ARGV[i],ARGC-i-1?sep:""}}' "${arr[@]}"

or

$ a=(1 "a b" 3)
$ b=$(IFS=, ; echo "${a[*]}")
$ echo $b
1,a b,3

Check if you also installed the "Google Repository". If not, you also have to install the "Google Repository" in your SDK Manager.

Also be aware that there might be 2 SDK installations - one coming from AndroidStudio and one you might have installed. Better consolidate this to one installation - this is a common pitfall - that you have it installed in one installation but it fails when you build with the other installation.

In onViewHolder set onClickListiner to any view and in side click use this code :

Toast.makeText(Drawer_bar.this, "position" + position, Toast.LENGTH_SHORT).show();

Replace Drawer_Bar with your Activity name.

This is a Kotlin based version, assuming that the parent view is an instance of LinearLayout.

someView.layoutParams = LinearLayout.LayoutParams(100, 200)

This allows to set the width and height (100 and 200) in a single line.

You need to return your promise to the calling function.

islogged:function(){
    var cUid=sessionService.get('uid');
    alert("in loginServce, cuid is "+cUid);
    var $checkSessionServer=$http.post('data/check_session.php?cUid='+cUid);
    $checkSessionServer.then(function(){
        alert("session check returned!");
        console.log("checkSessionServer is "+$checkSessionServer);
    });
    return $checkSessionServer; // <-- return your promise to the calling function
}

def import_path(fullpath):
    """ 
    Import a file with full path specification. Allows one to
    import from anywhere, something __import__ does not do. 
    """
    path, filename = os.path.split(fullpath)
    filename, ext = os.path.splitext(filename)
    sys.path.append(path)
    module = __import__(filename)
    reload(module) # Might be out of date
    del sys.path[-1]
    return module

I'm using this snippet to import modules from paths, hope that helps

You have a few options using programs along with grep. The simplest in my opinion is to use head:

head -n10 filename | grep ...

head will output the first 10 lines (using the -n option), and then you can pipe that output to grep.

For an advanced user text input is the best, if the user knows the date format, it is very fast. For a not so advanced user I suggest using a datepicker. Since usually you also have advanced and non-advanced users I suggest a combination of text input and datepicker.

As @arman-p pointed out MYSQL has no explode(). However, I think the solution presented in much more complicated than it needs to be. To do a quick check when you are given a comma delimited list string (e.g, list of the table keys to look for) you do:

SELECT 
    table_key, field_1, field_2, field_3
FROM
    my_table
WHERE
    field_3 = 'my_field_3_value'
    AND (comma_list = table_key
        OR comma_list LIKE CONCAT(table_key, ',%')
        OR comma_list LIKE CONCAT('%,', table_key, ',%')
        OR comma_list LIKE CONCAT('%,', table_key))

This assumes that you need to also check field_3 on the table too. If you do not need it, do not add that condition.

If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:

myTimer.Elapsed += PlayMusicEvent;

where

public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
    music.player.Stop();
    System.Timers.Timer myTimer = (System.Timers.Timer)sender;
    myTimer.Stop();
}

But you need to think about where to store your note.

Just to make things even worse, in some situations, no-cache can't be used, but no-store can:

http://faindu.wordpress.com/2008/04/18/ie7-ssl-xml-flex-error-2032-stream-error/

You need a table variable and it can be this simple.

declare @ID table (ID int)

insert into MyTable2(ID)
output inserted.ID into @ID
values (1)

Let's try this

select convert(varchar, getdate(), 108) 

Just try a few moment ago

You could try setInterval() instead:

var i = setInterval(function(){
   //Call ajax here
},10000)

The inArray function returns the index of the object supplied as the first argument to the function in the array supplied as the second argument to the function.

When inArray returns 0 it is indicating that the first argument was found at the first position of the supplied array.

To use inArray within an if statement use:

if(jQuery.inArray("test", myarray) != -1) {
    console.log("is in array");
} else {
    console.log("is NOT in array");
}

inArray returns -1 when the first argument passed to the function is not found in the array passed as the second argument.

Swift 5:

let dic = ["2": "B", "1": "A", "3": "C"]
let encoder = JSONEncoder()
if let jsonData = try? encoder.encode(dic) {
    if let jsonString = String(data: jsonData, encoding: .utf8) {
        print(jsonString)
    }
}

Note that keys and values must implement Codable. Strings, Ints, and Doubles (and more) are already Codable. See Encoding and Decoding Custom Types.

I think this way is more simple:

User resultUser = users.stream()
    .filter(user -> user.getId() > 0)
    .findFirst().get();

UINavigationBar.appearance().barTintColor

worked for me

after including bootstrap.min.js or uncompressed one, you can just add interval as a parameter as below jQuery("#numbers").carousel({'interval':900 }); It works for me

NSString objects are immutable (they can't be changed), but there is a mutable subclass, NSMutableString, that gives you several methods for replacing characters within a string. It's probably your best bet.

have this extension

Swift 2.*

extension UIApplication {
    class func topViewController(controller: UIViewController? = UIApplication.sharedApplication().keyWindow?.rootViewController) -> UIViewController? {
        if let navigationController = controller as? UINavigationController {
            return topViewController(navigationController.visibleViewController)
        }
        if let tabController = controller as? UITabBarController {
            if let selected = tabController.selectedViewController {
                return topViewController(selected)
            }
        }
        if let presented = controller?.presentedViewController {
            return topViewController(presented)
        }
        return controller
    }
}

Swift 3

extension UIApplication {
    class func topViewController(controller: UIViewController? = UIApplication.shared.keyWindow?.rootViewController) -> UIViewController? {
        if let navigationController = controller as? UINavigationController {
            return topViewController(controller: navigationController.visibleViewController)
        }
        if let tabController = controller as? UITabBarController {
            if let selected = tabController.selectedViewController {
                return topViewController(controller: selected)
            }
        }
        if let presented = controller?.presentedViewController {
            return topViewController(controller: presented)
        }
        return controller
    }
}

You can you use this anywhere on your controller

if let topController = UIApplication.topViewController() {

}

std::string var = "sometext" + somevar + "sometext" + somevar;

This doesn't work because the additions are performed left-to-right and "sometext" (the first one) is just a const char *. It has no operator+ to call. The simplest fix is this:

std::string var = std::string("sometext") + somevar + "sometext" + somevar;

Now, the first parameter in the left-to-right list of + operations is a std::string, which has an operator+(const char *). That operator produces a string, which makes the rest of the chain work.

You can also make all the operations be on var, which is a std::string and so has all the necessary operators:

var = "sometext";
var += somevar;
var += "sometext";
var += somevar;

I finally solved this by creating a second object that imitates B.

My schema now looks like this:

I now have B1 (within parent of A) and B2 outside of it.

B1 and B2 are right next to one another, so to the naked eye it looks as if it's just 1 object.

Here is the powershell script to delete a service foo

$foo= Get-WmiObject -Class Win32_Service -Filter "Name='foo'"
$foo.delete()

these 2 are the same:

Print CAST(GETDATE() as Datetime2 (3) )
PRINT (CONVERT( VARCHAR(24), GETDATE(), 121))

array_search should work fine, just tested this and it returns the keys as expected:

$list = array('string1', 'string2', 'string3');
echo "Key = ".array_search('string1', $list);
echo " Key = ".array_search('string2', $list);
echo " Key = ".array_search('string3', $list);

Or for the index, you could use

$list = array('string1', 'string2', 'string3');
echo "Index = ".array_search('string1', array_merge($list));
echo " Index = ".array_search('string2', array_merge($list));
echo " Index = ".array_search('string3', array_merge($list));

I resolved this issue by right clicking on the folder containing the files and choosing Exclude From Project and then right clicking again and selecting Include In Project (you first have to enable Show All Files to make the excluded folder visible)

I had a similar problem using Angular js. i had a rewrite all to index.html in my .htaccess. The solution was to add the correct path slashes in . Each situation is unique, but hope this helps someone.

The default port for SQL Server Database Engine is 1433.

And as a best practice it should always be changed after the installation. 1433 is widely known which makes it vulnerable to attacks.

Based on Jason Sebring's very useful tip, and on the stuff covered here and there, I found a perfect solution for my case:

Pseudo code with Javascript snippets:

1. immediately create a blank popup on user action

    var importantStuff = window.open('', '_blank');
   

   (Enrich the call to window.open with whatever additional options you need.)

   Optional: add some "waiting" info message. Examples:

   a) An external HTML page: replace the above line with

    var importantStuff = window.open('http://example.com/waiting.html', '_blank');
   

   b) Text: add the following line below the above one:

    importantStuff.document.write('Loading preview...');
   

2. fill it with content when ready (when the AJAX call is returned, for instance)

    importantStuff.location.href = 'https://example.com/finally.html';
   

   Alternatively, you could close the window here if you don't need it after all (if ajax request fails, for example - thanks to @Goose for the comment):

    importantStuff.close();
   

I actually use this solution for a mailto redirection, and it works on all my browsers (windows 7, Android). The _blank bit helps for the mailto redirection to work on mobile, btw.

Here is a simple thumb-rule that I use help me decide as when to use flatMap() over map() in Rx's Observable.

Once you come to a decision that you're going to employ a map transformation, you'd write your transformation code to return some Object right?

If what you're returning as end result of your transformation is:

• a non-observable object then you'd use just map(). And map() wraps that object in an Observable and emits it.

• an Observable object, then you'd use flatMap(). And flatMap() unwraps the Observable, picks the returned object, wraps it with its own Observable and emits it.

Say for example we've a method titleCase(String inputParam) that returns Titled Cased String object of the input param. The return type of this method can be String or Observable<String>.

• If the return type of titleCase(..) were to be mere String, then you'd use map(s -> titleCase(s))

• If the return type of titleCase(..) were to be Observable<String>, then you'd use flatMap(s -> titleCase(s))

Hope that clarifies.

or try NSString *string = [NSString stringWithFormat:@"%d", [NSNumber intValue], nil];

Here is a solution using the Shapely library. Shapely is often used for GIS work, but is built to be useful for computational geometry. I changed your inputs from lists to tuples.

Problem

# Given these endpoints
#line 1
A = (X, Y)
B = (X, Y)

#line 2
C = (X, Y)
D = (X, Y)

# Compute this:
point_of_intersection = (X, Y)

Solution

import shapely
from shapely.geometry import LineString, Point

line1 = LineString([A, B])
line2 = LineString([C, D])

int_pt = line1.intersection(line2)
point_of_intersection = int_pt.x, int_pt.y

print(point_of_intersection)

You should be able to use the current directory

"%CD%"\bin\Iris.exe

If you want to target a specific class and ID in CSS, then use a format like div.x#y {}.

For everyone stumbling upon this post because pandas gets mentioned, you now have the very elegant and straighforward option of directly accessing the secondary_y axis in pandas with ax.right_ax

So paraphrasing the example initially posted, you would write:

table = sql.read_frame(query,connection)

ax = table[[0, 1]].plot(ylim=(0,100), secondary_y=table[1])
ax.set_ylabel('$')
ax.right_ax.set_ylabel('Your second Y-Axis Label goes here!')

(this is already mentioned in these posts as well: 1 2)

You can use rake db:reset when you want to drop the local database and start fresh with data loaded from db/seeds.rb. This is a useful command when you are still figuring out your schema, and often need to add fields to existing models.

Once the reset command is used it will do the following: Drop the database: rake db:drop Load the schema: rake db:schema:load Seed the data: rake db:seed

But if you want to completely drop your database you can use rake db:drop. Dropping the database will also remove any schema conflicts or bad data. If you want to keep the data you have, be sure to back it up before running this command.

This is a detailed article about the most important rake database commands.

The right way is this:

Integer i = Integer.class.cast(obj);

The method cast() is a much safer alternative to compile-time casting.

Just in case any Windows users are having trouble, I thought I'd add my own experience. When running python manage.py runserver 0.0.0.0:8000, I could view urls using localhost:8000, but not my ip address 192.168.1.3:8000.

I ended up disabling ipv6 on my wireless adapter, and running ipconfig /renew. After this everything worked as expected.

Some addition to the previous answers. It is nice to regulate the density of the polygon to avoid obscuring the data points.

library(MASS)
attach(Boston)
lm.fit2 = lm(medv~poly(lstat,2))
plot(lstat,medv)
new.lstat = seq(min(lstat), max(lstat), length.out=100)
preds <- predict(lm.fit2, newdata = data.frame(lstat=new.lstat), interval = 'prediction')
lines(sort(lstat), fitted(lm.fit2)[order(lstat)], col='red', lwd=3) 
polygon(c(rev(new.lstat), new.lstat), c(rev(preds[ ,3]), preds[ ,2]), density=10, col = 'blue', border = NA)
lines(new.lstat, preds[ ,3], lty = 'dashed', col = 'red')
lines(new.lstat, preds[ ,2], lty = 'dashed', col = 'red')

Please note that you see the prediction interval on the picture, which is several times wider than the confidence interval. You can read here the detailed explanation of those two types of interval estimates.

function sortArgs(){ return [].slice.call(arguments).sort() }

// Returns the arguments object itself
function sortArgs(){ return [].sort.call(arguments) }

Some array methods are intentionally made not to require the target object to be an actual array. They only require the target to have a property named length and indices (which must be zero or larger integers).

[].sort.call({0:1, 1:0, length:2}) // => ({0:0, 1:1, length:2})

If you look for POSIX compliant solution:

cd DirsRoot && find . -type f -print -o -name . -o -prune

-maxdepth is not POSIX compliant option.

I tried vanstee's solution along with asp mvc 3 unobtrusive validation, and if client validation fails, code is still run, and form submit is disabled for good. I'm not able to resubmit after correcting fields. (see bjan's comment)

So I modified vanstee's script like this:

$("form").submit(function () {
    if ($(this).valid()) {
        $(this).submit(function () {
            return false;
        });
        return true;
    }
    else {
        return false;
    }
});

Similar to one of the answers above, but try adding .sort_values() to your .groupby() will allow you to change the sort order. If you need to sort on a single column, it would look like this:

df.groupby('group')['id'].count().sort_values(ascending=False)

ascending=False will sort from high to low, the default is to sort from low to high.

*Careful with some of these aggregations. For example .size() and .count() return different values since .size() counts NaNs.

What is the difference between size and count in pandas?

         a = in.nextInt();
         System.out.println("Number is= " + a);
     }
}

Prior Swift 3.0 :

String(data: yourData, encoding: NSUTF8StringEncoding)

For Swift 4.0:

String(data: yourData, encoding: .utf8)

This question already has a million-and-one answers and many of them are quite good, but I wanted to try and clarify when a BOM should or should not be used.

As mentioned, any use of the UTF BOM (Byte Order Mark) in determining whether a string is UTF-8 or not is educated guesswork. If there is proper metadata available (like charset="utf-8"), then you already know what you're supposed to be using, but otherwise you'll need to test and make some assumptions. This involves checking whether the file a string comes from begins with the hexadecimal byte code, EF BB BF.

If a byte code corresponding to the UTF-8 BOM is found, the probability is high enough to assume it's UTF-8 and you can go from there. When forced to make this guess, however, additional error checking while reading would still be a good idea in case something comes up garbled. You should only assume a BOM is not UTF-8 (i.e. latin-1 or ANSI) if the input definitely shouldn't be UTF-8 based on its source. If there is no BOM, however, you can simply determine whether it's supposed to be UTF-8 by validating against the encoding.

Why is a BOM not recommended?

1. Non-Unicode-aware or poorly compliant software may assume it's latin-1 or ANSI and won't strip the BOM from the string, which can obviously cause issues.
2. It's not really needed (just check if the contents are compliant and always use UTF-8 as the fallback when no compliant encoding can be found)

When should you encode with a BOM?

If you're unable to record the metadata in any other way (through a charset tag or file system meta), and the programs being used like BOMs, you should encode with a BOM. This is especially true on Windows where anything without a BOM is generally assumed to be using a legacy code page. The BOM tells programs like Office that, yes, the text in this file is Unicode; here's the encoding used.

When it comes down to it, the only files I ever really have problems with are CSV. Depending on the program, it either must, or must not have a BOM. For example, if you're using Excel 2007+ on Windows, it must be encoded with a BOM if you want to open it smoothly and not have to resort to importing the data.

Add the following code to add trim functionality to the string.

if(typeof String.prototype.trim !== 'function') {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, ''); 
  }
}

Another Way which worked for me is:

After dettaching before you attach

• -> go to the .mdf file -> right click & select properties on the file -> security tab -> Check Group or usernames:

  for your name\account (optional) and for "NT SERVICE\MSSQLSERVER"(NB)

List item

-> if not there than click on edit button -> click on add button

  and enter\search NT SERVICE\MSSQLSERVER

• -> click on OK -> give full rights -> apply then ok

  then ok again do this for .ldf file too.

then attach

Just press Alt+Shift+Q,c for quick access.(In windows)

Write the code using ASyncTask for http handling.

Bitmap b;
ImageView img;
......
try
    {
        URL url = new URL("http://10.119.120.10:80/img.jpg");
        InputStream is = new BufferedInputStream(url.openStream());
        b = BitmapFactory.decodeStream(is);
    } catch(Exception e){}
......
img.setImageBitmap(b);

Either make your friends download the runtime DLL (@Kay's answer), or compile the app with static linking.

In visual studio, go to Project tab -> properties - > configuration properties -> C/C++ -> Code Generation on runtime library choose /MTd for debug mode and /MT for release mode.

This will cause the compiler to embed the runtime into the app. The executable will be significantly bigger, but it will run without any need of runtime dlls.

Currently, i prefer using this methods:

String data = "Date from Register: ";
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
// Verify that OS.Version is > API 26 (OREO)
            DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd"); 
// Origin format
            LocalDate localDate = LocalDate.parse(capitalModels.get(position).getDataServer(), formatter); // Parse String (from server) to LocalDate
            DateTimeFormatter formatter1 = DateTimeFormatter.ofPattern("dd/MM/yyyy"); 
//Output format
            data = "Data de Registro: "+formatter1.format(localDate); // Output
            Toast.makeText(holder.itemView.getContext(), data, Toast.LENGTH_LONG).show();
        }else{ 
//Same resolutions, just use legacy methods to oldest android OS versions.
                SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd",Locale.getDefault());
            try {
                Date date = format.parse(capitalModels.get(position).getDataServer());
                SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy", Locale.getDefault());
                data = "Date from Register: "+formatter.format(date);
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }

The code you've shown will read 8 bytes. You could use

with open(filename, 'rb') as f:
   while 1:
      byte_s = f.read(1)
      if not byte_s:
         break
      byte = byte_s[0]
      ...

Linq With Or Condition by using Lambda expression you can do as below

DataTable dtEmp = new DataTable();

dtEmp.Columns.Add("EmpID", typeof(int));
dtEmp.Columns.Add("EmpName", typeof(string));
dtEmp.Columns.Add("Sal", typeof(decimal));
dtEmp.Columns.Add("JoinDate", typeof(DateTime));
dtEmp.Columns.Add("DeptNo", typeof(int));

dtEmp.Rows.Add(1, "Rihan", 10000, new DateTime(2001, 2, 1), 10);
dtEmp.Rows.Add(2, "Shafi", 20000, new DateTime(2000, 3, 1), 10);
dtEmp.Rows.Add(3, "Ajaml", 25000, new DateTime(2010, 6, 1), 10);
dtEmp.Rows.Add(4, "Rasool", 45000, new DateTime(2003, 8, 1), 20);
dtEmp.Rows.Add(5, "Masthan", 22000, new DateTime(2001, 3, 1), 20);


var res2 = dtEmp.AsEnumerable().Where(emp => emp.Field<int>("EmpID")
            == 1 || emp.Field<int>("EmpID") == 2);

foreach (DataRow row in res2)
{
    Label2.Text += "Emplyee ID: " + row[0] + "   &   Emplyee Name: " + row[1] + ",  ";
}

Many distinctions have already been mentioned. Here is one more:

Running npm install at the top of your source directory will run various scripts: prepublish, preinstall, install, postinstall. Depending on what these scripts do, a npm install may do considerably more work than just installing dependencies.

I've just had a use case where prepublish would call make and the Makefile was designed to fetch dependencies if the package.json got updated. Calling npm install from within the Makefile would have lead to an infinite recursion, while calling npm update worked just fine, installing all dependencies so that the build could proceed even if make was called directly.

If you're willing to use pseudo elements and let them insert content, you can do the following. It doesn't assume knowledge of the original element and doesn't require additional markup.

.element {
  text-indent: -9999px;
  line-height: 0; /* Collapse the original line */
}

.element::after {
  content: "New text";
  text-indent: 0;
  display: block;
  line-height: initial; /* New content takes up original line height */
}

JSFiddle Example

I recommend you stick with Laravel auth routes in web.php: Auth::routes()

It will create the following route:

POST | logout | App\Http\Controllers\Auth\LoginController@logout

You will need to logout using a POST form. This way you will also need the CSRF token which is recommended.

<form method="POST" action="{{ route('logout') }}">
  @csrf
  <button type="submit">Logout</button>
</form>

This worked for me :

import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.format.annotation.DateTimeFormat.ISO;

@Column(name="end_date", nullable = false)
@DateTimeFormat(iso = ISO.DATE_TIME)
@JsonFormat(pattern = "yyyy-MM-dd HH:mm")
private LocalDateTime endDate;

Sometimes by self-updating composer it solves the problem

php composer.phar self-update

Cheers

You can directly call the

pd.DataFrame()

method and pass your list as parameter.

l = ['Thanks You','Its fine no problem','Are you sure']
pd.DataFrame(l)

Output:

                      0
0            Thanks You
1   Its fine no problem
2          Are you sure

And if you have multiple lists and you want to make a dataframe out of it.You can do it as following:

import pandas as pd
names =["A","B","C","D"]
salary =[50000,90000,41000,62000]
age = [24,24,23,25]
data = pd.DataFrame([names,salary,age]) #Each list would be added as a row
data = data.transpose() #To Transpose and make each rows as columns
data.columns=['Names','Salary','Age'] #Rename the columns
data.head()

Output:

    Names   Salary  Age
0       A    50000   24
1       B    90000   24
2       C    41000   23
3       D    62000   25

What about a little trickery like NgModel does with NgForm? You have to register your parent as a provider, then load your parent in the constructor of the child.

That way, you don't have to put [sharedList] on all your children.

// Parent.ts
export var parentProvider = {
    provide: Parent,
    useExisting: forwardRef(function () { return Parent; })
};

@Component({
    moduleId: module.id,
    selector: 'parent',
    template: '<div><ng-content></ng-content></div>',
    providers: [parentProvider]
})
export class Parent {
    @Input()
    public sharedList = [];
}

// Child.ts
@Component({
    moduleId: module.id,
    selector: 'child',
    template: '<div>child</div>'
})
export class Child {
    constructor(private parent: Parent) {
        parent.sharedList.push('Me.');
    }
}

Then your HTML

<parent [sharedList]="myArray">
    <child></child>
    <child></child>
</parent>

You can find more information on the subject in the Angular documentation: https://angular.io/guide/dependency-injection-in-action#find-a-parent-component-by-injection

If you want to get specific columns using with() in laravel eloquent then you can use code as below which is originally answered by @Adam in his answer here in response of this same question :

Post::with('user:id,username')->get();

So i have used it in my code but it was giving me error of 1052: Column 'id' in field list is ambiguous, so if you guys are also facing same problem

Then for solving it you have to specify table name before the id column in with() method as below code:

Post::with('user:user.id,username')->get();

This happens when you do not include a message when you try to commit using:

git commit

It launches an editor environment. Quit it by typing :q! and hitting enter.

It's going to take you back to the terminal without committing, so make sure to try again, this time pass in a message:

git commit -m 'Initial commit'

I found 'running steps' (win32) software doing exactly what I was looking for: http://www.steppingsoftware.com/

You can load a bat file, place breakpoints / start stepping through it while seeing the output and environment variables.

The evaluation version only allows to step through 50 lines... Does anyone have a free alternative with similar functionality?

Firewalls are often the problem in these situations. Personally, the Mcafee enterprise firewall was causing this issue even for requests within the network.

Disable your firewalls or add a rule for tomcat and see if this helps.

Here's an example which issues the same warning:

import numpy as np
np.seterr(all='warn')
A = np.array([10])
a=A[-1]
a**a

yields

RuntimeWarning: overflow encountered in long_scalars

In the example above it happens because a is of dtype int32, and the maximim value storable in an int32 is 2**31-1. Since 10**10 > 2**32-1, the exponentiation results in a number that is bigger than that which can be stored in an int32.

Note that you can not rely on np.seterr(all='warn') to catch all overflow errors in numpy. For example, on 32-bit NumPy

>>> np.multiply.reduce(np.arange(21)+1)
-1195114496

while on 64-bit NumPy:

>>> np.multiply.reduce(np.arange(21)+1)
-4249290049419214848

Both fail without any warning, although it is also due to an overflow error. The correct answer is that 21! equals

In [47]: import math

In [48]: math.factorial(21)
Out[50]: 51090942171709440000L

According to numpy developer, Robert Kern,

Unlike true floating point errors (where the hardware FPU sets a flag whenever it does an atomic operation that overflows), we need to implement the integer overflow detection ourselves. We do it on the scalars, but not arrays because it would be too slow to implement for every atomic operation on arrays.

So the burden is on you to choose appropriate dtypes so that no operation overflows.

If you just want the old file in your working copy:

svn up -r 147 myfile.py

If you want to rollback, see this "How to return to an older version of our code in subversion?".

you can remove last comma from a string by using slice() method, find the below example:

var strVal = $.trim($('.txtValue').val());
var lastChar = strVal.slice(-1);
if (lastChar == ',') {
    strVal = strVal.slice(0, -1);
}

Here is an Example

function myFunction() {_x000D_
 var strVal = $.trim($('.txtValue').text());_x000D_
 var lastChar = strVal.slice(-1);_x000D_
 if (lastChar == ',') { // check last character is string_x000D_
  strVal = strVal.slice(0, -1); // trim last character_x000D_
  $("#demo").text(strVal);_x000D_
 }_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<p class="txtValue">Striing with Commma,</p>_x000D_
_x000D_
<button onclick="myFunction()">Try it</button>_x000D_
_x000D_
<p id="demo"></p>

You can get a more detailed list (e.g. structured by defining class) with gems like debugging or looksee.

This is for Mac OS X with the native installation of Apache HTTP and custom installation of MySQL.

The answer is based on @alec-gorge's excellent response, but since I had to google some specific changes to have it configured in my configuration, mostly Mac OS X-specific, I thought I'd add it here for the sake of completeness.

Enable PHP5 support for Apache HTTP

Make sure the PHP5 support is enabled in /etc/apache2/httpd.conf.

Edit the file with sudo vi /etc/apache2/httpd.conf (enter the password when asked) and uncomment (remove ; from the beginning of) the line to load the php5_module module.

LoadModule php5_module libexec/apache2/libphp5.so

Start Apache HTTP with sudo apachectl start (or restart if it's already started and needs to be restarted to re-read the configuration file).

Make sure that /var/log/apache2/error_log contains a line that tells you the php5_module is enabled - you should see PHP/5.3.15 (or similar).

[notice] Apache/2.2.22 (Unix) DAV/2 PHP/5.3.15 with Suhosin-Patch configured -- resuming normal operations

Looking up Socket file's name

When MySQL is up and running (with ./bin/mysqld_safe) there should be debug lines printed out to the console that tell you where you can find the log files. Note the hostname in the file name - localhost in my case - that may be different for your configuration.

The file that comes after Logging to is important. That's where MySQL logs its work.

130309 12:17:59 mysqld_safe Logging to '/Users/jacek/apps/mysql/data/localhost.err'.
130309 12:17:59 mysqld_safe Starting mysqld daemon with databases from /Users/jacek/apps/mysql/data

Open the localhost.err file (again, yours might be named differently), i.e. tail -1 /Users/jacek/apps/mysql/data/localhost.err to find out the socket file's name - it should be the last line.

$ tail -1 /Users/jacek/apps/mysql/data/localhost.err
Version: '5.5.27'  socket: '/tmp/mysql.sock'  port: 3306  MySQL Community Server (GPL)

Note the socket: part - that's the socket file you should use in php.ini.

There's another way (some say an easier way) to determine the location of the socket's file name by logging in to MySQL and running:

show variables like '%socket%';

Configuring PHP5 with MySQL support - /etc/php.ini

Speaking of php.ini...

In /etc directory there's /etc/php.ini.default file. Copy it to /etc/php.ini.

sudo cp /etc/php.ini.default /etc/php.ini

Open /etc/php.ini and look for mysql.default_socket.

sudo vi /etc/php.ini

The default of mysql.default_socket is /var/mysql/mysql.sock. You should change it to the value you have noted earlier - it was /tmp/mysql.sock in my case.

Replace the /etc/php.ini file to reflect the socket file's name:

mysql.default_socket = /tmp/mysql.sock
mysqli.default_socket = /tmp/mysql.sock

Final verification

Restart Apache HTTP.

sudo apachectl restart 

Check the logs if there are no error related to PHP5. No errors means you're done and PHP5 with MySQL should work fine. Congrats!

Try this.

var string = "         string             1";
string = string.trim().replace(/\s+/g, ' ');

the result will be

string 1

What happened here is that it will trim the outside spaces first using trim() then trim the inside spaces using .replace(/\s+/g, ' ').

This seems to happen when there's a generic problem with your data source that it isn't handling.

In my case I had inserted a bunch of data, the indexes had become corrupt on the table, they needed rebuilding. I found a script to rebuild them all, seemed to fix it. To find the error I ran the same query on the database - one that had worked 100+ times previously.

I wanted something without external dependencies, with strict bash support (-u), and I needed it to work on even the older bash versions. This handles various types of params:

• short bools (-h)
• short options (-i "image.jpg")
• long bools (--help)
• equals options (--file="filename.ext")
• space options (--file "filename.ext")
• concatinated bools (-hvm)

Just insert the following at the top of your script:

# Check if a list of params contains a specific param
# usage: if _param_variant "h|?|help p|path f|file long-thing t|test-thing" "file" ; then ...
# the global variable $key is updated to the long notation (last entry in the pipe delineated list, if applicable)
_param_variant() {
  for param in $1 ; do
    local variants=${param//\|/ }
    for variant in $variants ; do
      if [[ "$variant" = "$2" ]] ; then
        # Update the key to match the long version
        local arr=(${param//\|/ })
        let last=${#arr[@]}-1
        key="${arr[$last]}"
        return 0
      fi
    done
  done
  return 1
}

# Get input parameters in short or long notation, with no dependencies beyond bash
# usage:
#     # First, set your defaults
#     param_help=false
#     param_path="."
#     param_file=false
#     param_image=false
#     param_image_lossy=true
#     # Define allowed parameters
#     allowed_params="h|?|help p|path f|file i|image image-lossy"
#     # Get parameters from the arguments provided
#     _get_params $*
#
# Parameters will be converted into safe variable names like:
#     param_help,
#     param_path,
#     param_file,
#     param_image,
#     param_image_lossy
#
# Parameters without a value like "-h" or "--help" will be treated as
# boolean, and will be set as param_help=true
#
# Parameters can accept values in the various typical ways:
#     -i "path/goes/here"
#     --image "path/goes/here"
#     --image="path/goes/here"
#     --image=path/goes/here
# These would all result in effectively the same thing:
#     param_image="path/goes/here"
#
# Concatinated short parameters (boolean) are also supported
#     -vhm is the same as -v -h -m
_get_params(){

  local param_pair
  local key
  local value
  local shift_count

  while : ; do
    # Ensure we have a valid param. Allows this to work even in -u mode.
    if [[ $# == 0 || -z $1 ]] ; then
      break
    fi

    # Split the argument if it contains "="
    param_pair=(${1//=/ })
    # Remove preceeding dashes
    key="${param_pair[0]#--}"

    # Check for concatinated boolean short parameters.
    local nodash="${key#-}"
    local breakout=false
    if [[ "$nodash" != "$key" && ${#nodash} -gt 1 ]]; then
      # Extrapolate multiple boolean keys in single dash notation. ie. "-vmh" should translate to: "-v -m -h"
      local short_param_count=${#nodash}
      let new_arg_count=$#+$short_param_count-1
      local new_args=""

      eval set -- "${new_args# }"
    fi
    if ! $breakout ; then
      key="$nodash"
    fi

    # By default we expect to shift one argument at a time
    shift_count=1
    if [ "${#param_pair[@]}" -gt "1" ] ; then
      # This is a param with equals notation
      value="${param_pair[1]}"
    else
      # This is either a boolean param and there is no value,
      # or the value is the next command line argument
      # Assume the value is a boolean true, unless the next argument is found to be a value.
      value=true
      if [[ $# -gt 1 && -n "$2" ]]; then
        local nodash="${2#-}"
        if [ "$nodash" = "$2" ]; then
          # The next argument has NO preceding dash so it is a value
          value="$2"
          shift_count=2
        fi
      fi
    fi

    # Check that the param being passed is one of the allowed params
    if _param_variant "$allowed_params" "$key" ; then
      # --key-name will now become param_key_name
      eval param_${key//-/_}="$value"
    else
      printf 'WARNING: Unknown option (ignored): %s\n' "$1" >&2
    fi
    shift $shift_count
  done
}

And use it like so:

# Assign defaults for parameters
param_help=false
param_path=$(pwd)
param_file=false
param_image=true
param_image_lossy=true
param_image_lossy_quality=85

# Define the params we will allow
allowed_params="h|?|help p|path f|file i|image image-lossy image-lossy-quality"

# Get the params from arguments provided
_get_params $*

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

For a bandpass filter, ws is a tuple containing the lower and upper corner frequencies. These represent the digital frequency where the filter response is 3 dB less than the passband.

wp is a tuple containing the stop band digital frequencies. They represent the location where the maximum attenuation begins.

gpass is the maximum attenutation in the passband in dB while gstop is the attentuation in the stopbands.

Say, for example, you wanted to design a filter for a sampling rate of 8000 samples/sec having corner frequencies of 300 and 3100 Hz. The Nyquist frequency is the sample rate divided by two, or in this example, 4000 Hz. The equivalent digital frequency is 1.0. The two corner frequencies are then 300/4000 and 3100/4000.

Now lets say you wanted the stopbands to be down 30 dB +/- 100 Hz from the corner frequencies. Thus, your stopbands would start at 200 and 3200 Hz resulting in the digital frequencies of 200/4000 and 3200/4000.

To create your filter, you'd call buttord as

fs = 8000.0
fso2 = fs/2
N,wn = scipy.signal.buttord(ws=[300/fso2,3100/fso2], wp=[200/fs02,3200/fs02],
   gpass=0.0, gstop=30.0)

The length of the resulting filter will be dependent upon the depth of the stop bands and the steepness of the response curve which is determined by the difference between the corner frequency and stopband frequency.

EugeneXa mentioned it in a comment, but it deserves to be an answer:

var template = $("#modal_template").html().trim();

This trims the offending whitespace from the beginning of the string. I used it with Mustache, like so:

var markup = Mustache.render(template, data);
$(markup).appendTo(container);

If you have Python version >= 2.7, you can use subprocess.check_output which basically does exactly what you want (it returns standard output as string).

Simple example (linux version, see note):

import subprocess

print subprocess.check_output(["ping", "-c", "1", "8.8.8.8"])

Note that the ping command is using linux notation (-c for count). If you try this on Windows remember to change it to -n for same result.

As commented below you can find a more detailed explanation in this other answer.

Accessing controller method means accessing a method on parent scope from directive controller/link/scope.

If the directive is sharing/inheriting the parent scope then it is quite straight forward to just invoke a parent scope method.

Little more work is required when you want to access parent scope method from Isolated directive scope.

There are few options (may be more than listed below) to invoke a parent scope method from isolated directives scope or watch parent scope variables (option#6 specially).

Note that I used link function in these examples but you can use a directive controller as well based on requirement.

Option#6: Through $watch and $watchCollection It is two way binding for items in all above examples, if items are modified in parent scope, items in directive would also reflect the changes.

If you want to watch other attributes or objects from parent scope, you can do that using $watch and $watchCollection as given below

      <td>
        <input type="text" ng-model="id" />
      </td>
    </tr>
    <tr>
      <td>Name:</td>
      <td>

      currentItem: '=',
      items: '=',
      selectedItems: '=ngModel'

      scope.$watchCollection('currentItem', function() {
        console.log(JSON.stringify(scope.currentItem));
      });
      scope.$watch('name', function() {
        console.log(JSON.stringify(scope.name));
      });
    }
  }
})

 app.controller('MainCtrl', function($scope) {
  $scope.user = 'World';

  $scope.addItem = function() {
    $scope.items.push({
      id: $scope.id,
      name: $scope.name,
      model: $scope.model
    });
    $scope.currentItem = {};
    $scope.currentItem.id = $scope.id;
    $scope.currentItem.name = $scope.name;
    $scope.currentItem.model = $scope.model;
  }

  $scope.selectedItems = ["allItems"];

  $scope.items = [{
    "id": "allItems",
    "name": "All Items",
    "order": 0
  }, {
    "id": "CaseItem",
    "name": "Case Item",
    "model": "PredefinedModel"
  }, {
    "id": "Application",
    "name": "Application",

});

You can always refer AngularJs documentation for detailed explanations about directives.

How about sys.exit() from the module sys.

If sys.exit() is executed from within a thread it will close that thread only.

This answer here talks about that: Why does sys.exit() not exit when called inside a thread in Python?

The way that setuptools does it, it uses the pkg_resources.parse_version function. It should be PEP440 compliant.

Example:

#! /usr/bin/python
# -*- coding: utf-8 -*-
"""Example comparing two PEP440 formatted versions
"""
import pkg_resources

VERSION_A = pkg_resources.parse_version("1.0.1-beta.1")
VERSION_B = pkg_resources.parse_version("v2.67-rc")
VERSION_C = pkg_resources.parse_version("2.67rc")
VERSION_D = pkg_resources.parse_version("2.67rc1")
VERSION_E = pkg_resources.parse_version("1.0.0")

print(VERSION_A)
print(VERSION_B)
print(VERSION_C)
print(VERSION_D)

print(VERSION_A==VERSION_B) #FALSE
print(VERSION_B==VERSION_C) #TRUE
print(VERSION_C==VERSION_D) #FALSE
print(VERSION_A==VERSION_E) #FALSE

SELECT CONVERT_TZ() will work for that.but its not working for me.

Why, what error do you get?

SELECT CONVERT_TZ(displaytime,'GMT','MET');

should work if your column type is timestamp, or date

http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_convert-tz

Test how this works:

SELECT CONVERT_TZ(a_ad_display.displaytime,'+00:00','+04:00');

Check your timezone-table

SELECT * FROM mysql.time_zone;
SELECT * FROM mysql.time_zone_name;

http://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html

If those tables are empty, you have not initialized your timezone tables. According to link above you can use mysql_tzinfo_to_sql program to load the Time Zone Tables. Please try this

shell> mysql_tzinfo_to_sql /usr/share/zoneinfo

or if not working read more: http://dev.mysql.com/doc/refman/5.5/en/mysql-tzinfo-to-sql.html

Arrays in PHP are associative arrays (otherwise known as dictionaries or hashes) by default. If you don't explicitly assign a key to a value, the interpreter will silently do that for you. So, the expression you've got up there iterates through $user_list, making the key available as $user and the value available as $pass as local variables in the body of the foreach.

With Me I had the library ticked under Eclipse>Project Properties>Android what I just did was uncheck the ticked library.

First off, I use nvm on linux machine.

When looking at the documentation for nvm at https://www.npmjs.org/package/nvm, it recommendations that you install nvm globally using the -g switch.

npm install -g nvm

Also there is a . in the path variable that they recommend.

export PATH=./node_modules/.bin:$PATH

so maybe your path should be

C:\Program Files (x86)\nodejs\node_modules\npm\\.bin

You can do it like the other people before me told you using a look:

A.) Use .data of the button element to share a look variable (or a just global variable)

if ($('#buttonId').data('locked') == 1)
    return
$('#buttonId').data('locked') = 1;
// Do your thing
$('#buttonId').data('locked') = 0;

B.) Disable mouse signals

$("#buttonId").css("pointer-events", "none");
// Do your thing
$("#buttonId").css("pointer-events", "auto");

C.) If it is a HTML button you can disable it (input [type=submit] or button)

$("#buttonId").attr("disabled", "true");
// Do your thing
$("#buttonId").attr("disabled", "false");

But watch out for other threads! I failed many times because my animation (fading in or out) took one second. E.g. fadeIn/fadeOut supports a callback function as second parameter. If there is no other way just do it using setTimeout(callback, delay).

Updated to High Sierra 10.13.2

xcode-select --install ALONE did not work for me.

1. Download X-code from app store

2. $xcode-select --install
   a. May need to update after install using softwareupdate in command line. $sudo softwareupdate -i "Command Line Tools (macOS High Sierra version 10.13) for Xcode-9.1"

3. $sudo xcodebuild -license

You can use sudo apt remove ruby

I hope I understand your question, but the ng-model directive creates a two-way binding between the selected item in the control and the value of item.selectedVariant. This means that changing item.selectedVariant in JavaScript, or changing the value in the control, updates the other. If item.selectedVariant has a value of 0, that item should get selected.

If variants is an array of objects, item.selectedVariant must be set to one of those objects. I do not know which information you have in your scope, but here's an example:

JS:

$scope.options = [{ name: "a", id: 1 }, { name: "b", id: 2 }];
$scope.selectedOption = $scope.options[1];

HTML:

<select data-ng-options="o.name for o in options" data-ng-model="selectedOption"></select>

This would leave the "b" item to be selected.

ALTER TABLE YourTableNameHere ALTER COLUMN YourColumnNameHere VARCHAR(20) this is perfect for change to datatype

#reading out the file at once in a list and then printing one-by-one
f=open('file.txt')
for i in list(f.read()):
    print(i)

Using the excellent request module:

var request = require('request');
  request("http://stackoverflow.com", {method: 'HEAD'}, function (err, res, body){
  console.log(res.headers);
});

You can change the method to GET if you wish, but using HEAD will save you from getting the entire response body if you only wish to look at the headers.

Although all of the answers fix the issue but they come with trade-offs/adjustments/compromises like

• floats, You have to float elements
• border-top, This pushes the parent at least 1px downwards which should then be adjusted with introducing -1px margin to the parent element itself. This can create problems when parent already has margin-top in relative units.
• padding-top, same effect as using border-top
• overflow: hidden, Can't be used when parent should display overflowing content, like a drop down menu
• overflow: auto, Introduces scrollbars for parent element that has (intentionally) overflowing content (like shadows or tool tip's triangle)

The issue can be resolved by using CSS3 pseudo elements as follows

.parent::before {
  clear: both;
  content: "";
  display: table;
  margin-top: -1px;
  height: 0;
}

Here is a small modification to Ryan Artecona's answer for canvases with a variable (%) width:

 HTMLCanvasElement.prototype.relMouseCoords = function (event) {
    var totalOffsetX = 0;
    var totalOffsetY = 0;
    var canvasX = 0;
    var canvasY = 0;
    var currentElement = this;

    do {
        totalOffsetX += currentElement.offsetLeft;
        totalOffsetY += currentElement.offsetTop;
    }
    while (currentElement = currentElement.offsetParent)

    canvasX = event.pageX - totalOffsetX;
    canvasY = event.pageY - totalOffsetY;

    // Fix for variable canvas width
    canvasX = Math.round( canvasX * (this.width / this.offsetWidth) );
    canvasY = Math.round( canvasY * (this.height / this.offsetHeight) );

    return {x:canvasX, y:canvasY}
}

Follow this pattern if you browsing for image files:

dialog.Filter =  "Image files (*.jpg, *.jpeg, *.jpe, *.jfif, *.png) | *.jpg; *.jpeg; *.jpe; *.jfif; *.png";

Like this:

$(document).ready(function ()
{
    document.title = "Hello World!";
});

Be sure to set a default-title if you want your site to be properly indexed by search-engines.

A little tip:

$(function ()
{
    // this is a shorthand for the whole document-ready thing
    // In my opinion, it's more readable 
});

Have a look at the ImageView API. There are several setImage* methods. Which one to use depends on the image you provide. If you have the image as resource (e.g. file res/drawable/my_image.png)

ImageView img = new ImageView(this);  // or (ImageView) findViewById(R.id.myImageView);
img.setImageResource(R.drawable.my_image);

I know it is very late but following approach can also be used:

<select id="type" name="type" >
    <option value="Permanent" id="permanent">I am here to stay.</option>
    <option value="toremove" id="toremove">Remove me!</option>
    <option value="Other" id="other">Other</option>
</select>

and if I have to remove second option (id=toremove), the script would look like

$('#toremove').hide();

As explained here, The “Iterable” was introduced to be able to use in the foreach loop. A class implementing the Iterable interface can be iterated over.

Iterator is class that manages iteration over an Iterable. It maintains a state of where we are in the current iteration, and knows what the next element is and how to get it.

All you actually need is "filter":

blur(«WhatEverYouWantInPixels»);"

body {_x000D_
    color: #fff;_x000D_
    font-family: Helvetica, Arial, sans-serif;_x000D_
}_x000D_

_x000D_
    /* You can adjust the blur-radius as you'd like */_x000D_
    filter: blur(3px);_x000D_
}

When you have JSON data then the following error appears

A better solution is to assign a var data for the local json array object, details see: https://datatables.net/manual/tech-notes/4

This is helps you to display table contents.

 $(document).ready(function(){   

        $('#customer_table').DataTable( {
         "aaData": data,

           "aoColumns": [{
                            "mDataProp": "name_en"
                        }, {
                            "mDataProp": "phone"
                        }, {
                            "mDataProp": "email"
                        }, {
                            "mDataProp": "facebook"
                        }]
            });
        });

The main reason for this is when the database is open somewhere else.

This could be as already said by many others:

• not being closed properly somewhere
• already open somewhere

When recently I had the same problem although different versions, I started to search for the reason.

In my case I had an excel file that queried data from the database.

In case the excel file is opened before the database, access would give this error.

Conclusion:

Check all files/connections related to the database. An open ODBC connection or query used in excel (my case) open the mdb file and will make it readonly.

If you are using Google fonts I would suggest the following.

If you want the fonts to run from your localhost or server you need to download the files.

Instead of downloading the ttf packages in the download links, use the live link they provide, for example:

http://fonts.googleapis.com/css?family=Source+Sans+Pro:300,400,600,300italic,400italic,600italic

Paste the URL in your browser and you should get a font-face declaration similar to the first answer.

Open the URLs provided, download and rename the files.

Stick the updated font-face declarations with relative paths to the woff files in your CSS, and you are done.

Try this:

If Len(vValue & vbNullString) > 0 Then
  ' we have a non-Null and non-empty String value
  doSomething()
Else
  ' We have a Null or empty string value
  doSomethingElse()
End If

You can also remove the line

  require: 'ngModel',

if you don't need ngModel in this directive. Removing ngModel will allow you to make a directive without thatngModel error.

You don't specify which shell (there are many), so I am assuming Bourne Shell, that is I think your script starts with:

#!/bin/sh

Please remember to tag future questions with the shell type, as this will help the community answer your question.

You need to define your functions before you call them. Using ():

process_install()
{
    echo "Performing process_install() commands, using arguments [${*}]..."
}

process_exit()
{
    echo "Performing process_exit() commands, using arguments [${*}]..."
}

Then you can call your functions, just as if you were calling any command:

if [ "$choice" = "true" ]
then
    process_install foo bar
elif [ "$choice" = "false" ]
then
    process_exit baz qux

You may also wish to check for invalid choices at this juncture...

else
    echo "Invalid choice [${choice}]..."
fi

See it run with three different values of ${choice}.

Good luck!

The 00947 message indicates that the record which you are trying to send to Oracle lacks one or more of the columns which was included at the time the table was created. The 00913 message indicates that the record which you are trying to send to Oracle includes more columns than were included at the time the table was created. You just need to check the number of columns and its type in both the tables ie the tables that are involved in the sql.

You can simplify things quite a bit by creating a class that derives from WebClient, overriding its GetWebRequest method and setting a CookieContainer object on it. If you always set the same CookieContainer instance, then cookie management will be handled automatically for you.

But the only way to get at the HttpWebRequest before it is sent is to inherit from WebClient and override that method.

public class CookieAwareWebClient : WebClient
{
    private CookieContainer cookie = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = cookie;
        }
        return request;
    }
}

var client = new CookieAwareWebClient();
client.BaseAddress = @"https://www.site.com/any/base/url/";
var loginData = new NameValueCollection();
loginData.Add("login", "YourLogin");
loginData.Add("password", "YourPassword");
client.UploadValues("login.php", "POST", loginData);

//Now you are logged in and can request pages    
string htmlSource = client.DownloadString("index.php");

For Windows : Using batch program.

Write this code in a text file and save it.

REM Delete eval folder with licence key and options.xml which contains a reference  to it
for %%I in ("WebStorm", "IntelliJ", "CLion", "Rider", "GoLand", "PhpStorm") do (

Now rename the file fileName.txt to fileName.bat

Close phpstorm if running. Disconnect internet. Then run the file. Open phpstorm again. If nothing goes wrong you will see the magic.

worst case : If phpstorm still shows "License Expired", at first uninstall and then apply the above technique.

To avoid using integer values to identify the VideoCapture properties, one can use, e.g., cv2.cv.CV_CAP_PROP_FPS in OpenCV 2.4 and cv2.CAP_PROP_FPS in OpenCV 3.0. (See also Stefan's comment below.)

Here a utility function that works for both OpenCV 2.4 and 3.0:

# returns OpenCV VideoCapture property id given, e.g., "FPS"
def capPropId(prop):
  return getattr(cv2 if OPCV3 else cv2.cv,
    ("" if OPCV3 else "CV_") + "CAP_PROP_" + prop)

OPCV3 is set earlier in my utilities code like this:

from pkg_resources import parse_version
OPCV3 = parse_version(cv2.__version__) >= parse_version('3')

Opening a file creates it and (unless append ('a') is set) overwrites it with emptyness, such as this:

open(filename, 'w').close()

I had that problem when I upgraded Postgres to 9.3.x. The quick fix for me was to downgrade to whichever 9.2.x version I had before (no need to install a new one).

$ ls /usr/local/Cellar/postgresql/
9.2.4
9.3.2
$ brew switch postgresql 9.2.4
$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
<open a new Terminal tab or window to reload>
$ psql

"Homebrew install specific version of formula?" offers a much more comprehensive explanation along with alternative ways to fix the problem.

Say you have defined your class like this:

    @Data
    @AllArgsConstructor(staticName = "of")
    private class Pair<P,Q> {

        public P first;
        public Q second;
    }

So when you will need to create a new instance, it will need to take the parameters and you will provide it like this as defined in the annotation.

Pair<Integer, String> pair = Pair.of(menuItemId, category);

If you define it like this, you will get the error asked for.

Pair<Integer, String> pair = new Pair(menuItemId, category);

Most voted solution is wrong, as cannot work with few buttons in one row.

Best solution will be the following code:

private void dataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            var senderGrid = (DataGridView)sender;

            if (e.ColumnIndex == senderGrid.Columns["Opn"].Index && e.RowIndex >= 0)
            {
                MessageBox.Show("Opn Click");
            }

            if (e.ColumnIndex == senderGrid.Columns["VT"].Index && e.RowIndex >= 0)
            {
                MessageBox.Show("VT Click");
            }
        }

This is the is simplest solution that worked for me.

<div
  contentEditable='true'
  onInput={e => console.log('Text inside div', e.currentTarget.textContent)}
>
Text inside div
</div>

Use FirstOrDefault insted of SingleOrDefault..

SingleOrDefault returns a SINGLE element or null if no element is found. If 2 elements are found in your Enumerable then it throws the exception you are seeing

FirstOrDefault returns the FIRST element it finds or null if no element is found. so if there are 2 elements that match your predicate the second one is ignored

   public int GetPackage(int id,int emp)
           {
             int getpackages=Convert.ToInt32(EmployerSubscriptionPackage.GetAllData().Where(x
   => x.SubscriptionPackageID ==`enter code here` id && x.EmployerID==emp ).FirstOrDefault().ID);
               return getpackages;
           }

 1. var EmployerId = Convert.ToInt32(Session["EmployerId"]);
               var getpackage = GetPackage(employerSubscription.ID, EmployerId);

$('inputFile').parent().parent().children('td > label').hide();

can help you navigate two levels up ( to TD, to TR ) moving two levels back down ( all TD's in that TR and their LABEL tags ), applying the hide() function there.

if you want to stay at the TR level and hide them:

$('inputFile').parent().parent().hide();

… is sufficient.

you can navigate very easily through the elements using the jquery selectors.

parent is documented here: http://api.jquery.com/parent/

hide is documented here: http://api.jquery.com/hide/

Instead of trying to modify the $scope within the service, you can implement a $watch within your controller to watch a property on your service for changes and then update a property on the $scope. Here is an example you might try in a controller:

angular.module('cfd')
    .controller('MyController', ['$scope', 'StudentService', function ($scope, StudentService) {

        $scope.students = null;

        (function () {
            $scope.$watch(function () {
                return StudentService.students;
            }, function (newVal, oldVal) {
                if ( newValue !== oldValue ) {
                    $scope.students = newVal;
                }
            });
        }());
    }]);

One thing to note is that within your service, in order for the students property to be visible, it needs to be on the Service object or this like so:

this.students = $http.get(path).then(function (resp) {
  return resp.data;
});

Reasons for this issues are:

1. Any one application may be running on this port like Skype.
2. Node may have crashed and port may not have been freed.
3. You may have tried to start server more than one. To solve this problem, one can maintain a boolean to check whether server have been started or not. It should be started only if boolean return false or undefined;

You can use ESCAPE:

WHERE columnName LIKE '%\%%' ESCAPE '\'

a possible solution in js

In case the WebSocket server initiative disconnects the ws link after a few minutes there no messages sent between the server and client.

1. client sends a custom ping message, to keep alive by using the keepAlive function

2. server ignore the ping message and response a custom pong message

var timerID = 0; 
function keepAlive() { 
    var timeout = 20000;  
    if (webSocket.readyState == webSocket.OPEN) {  
        webSocket.send('');  
    }  
    timerId = setTimeout(keepAlive, timeout);  
}  
function cancelKeepAlive() {  
    if (timerId) {  
        clearTimeout(timerId);  
    }  
}

dispatch_queue_t queue = dispatch_queue_create("com.example.MyQueue", NULL);

  dispatch_async(dispatch_get_main_queue(), ^{
    // Update the UI on the main thread.
  });
});

During a project I noticed I was repeating myself too much with the optional parameters and settings, so I made a class that handles the type checking and assigns a default value which results in neat and readable code. See example and let me know if this works for you.

var myCar           = new Car('VW', {gearbox:'automatic', options:['radio', 'airbags 2x']});
var myOtherCar      = new Car('Toyota');

function Car(brand, settings) {
    this.brand      = brand;

    // readable and adjustable code
    settings        = DefaultValue.object(settings, {});
    this.wheels     = DefaultValue.number(settings.wheels, 4);
    this.hasBreaks  = DefaultValue.bool(settings.hasBreaks, true);
    this.gearbox    = DefaultValue.string(settings.gearbox, 'manual');
    this.options    = DefaultValue.array(settings.options, []);

    // instead of doing this the hard way
    settings        = settings || {};
    this.wheels     = (!isNaN(settings.wheels)) ? settings.wheels : 4;
    this.hasBreaks  = (typeof settings.hasBreaks !== 'undefined') ? (settings.hasBreaks === true) : true;
    this.gearbox    = (typeof settings.gearbox === 'string') ? settings.gearbox : 'manual';
    this.options    = (typeof settings.options !== 'undefined' && Array.isArray(settings.options)) ? settings.options : [];
}

Using this class:

(function(ns) {

    var DefaultValue = {

        object: function(input, defaultValue) {
            if (typeof defaultValue !== 'object') throw new Error('invalid defaultValue type');
            return (typeof input !== 'undefined') ? input : defaultValue;
        },

        bool: function(input, defaultValue) {
            if (typeof defaultValue !== 'boolean') throw new Error('invalid defaultValue type');
            return (typeof input !== 'undefined') ? (input === true) : defaultValue;
        },

        number: function(input, defaultValue) {
            if (isNaN(defaultValue)) throw new Error('invalid defaultValue type');
            return (typeof input !== 'undefined' && !isNaN(input)) ? parseFloat(input) : defaultValue;
        },

        // wrap the input in an array if it is not undefined and not an array, for your convenience
        array: function(input, defaultValue) {
            if (typeof defaultValue === 'undefined') throw new Error('invalid defaultValue type');
            return (typeof input !== 'undefined') ? (Array.isArray(input) ? input : [input]) : defaultValue;
        },

        string: function(input, defaultValue) {
            if (typeof defaultValue !== 'string') throw new Error('invalid defaultValue type');
            return (typeof input === 'string') ? input : defaultValue;
        },

    };

    ns.DefaultValue = DefaultValue;

}(this));

Thank you all for your great answers! Spent quite some time searching for a solution, and on my side I was making an elementary mistake: I was calling bodyParser.json() from within the function :

  /.../_x000D_

})

I just needed to do app.use(['/password'], bodyParser.json()) and it worked...

You should be using indexes to help SQL server performance. Usually that implies that columns that are used to find rows in a table are indexed.

Clustered indexes makes SQL server order the rows on disk according to the index order. This implies that if you access data in the order of a clustered index, then the data will be present on disk in the correct order. However if the column(s) that have a clustered index is frequently changed, then the row(s) will move around on disk, causing overhead - which generally is not a good idea.

Having many indexes is not good either. They cost to maintain. So start out with the obvious ones, and then profile to see which ones you miss and would benefit from. You do not need them from start, they can be added later on.

Most column datatypes can be used when indexing, but it is better to have small columns indexed than large. Also it is common to create indexes on groups of columns (e.g. country + city + street).

Also you will not notice performance issues until you have quite a bit of data in your tables. And another thing to think about is that SQL server needs statistics to do its query optimizations the right way, so make sure that you do generate that.

In my case this was happening after update to Android 8.0. The self-signed certificate Android was set to trust was using signature algorithm SHA1withRSA. Switching to a new cert, using signature algorithm SHA256withRSA fixed the problem.

You are looking for the float.h header.

For an activity you can use this approach to specify a subtitle, along with the title, in the manifest.

Manifest:

<activity
    android:name=".MyActivity"
    android:label="@string/my_title"
    android:description="@string/my_subtitle">
</activity>

Activity:

try {
    ActivityInfo activityInfo = getPackageManager().getActivityInfo(getComponentName(), PackageManager.GET_META_DATA);
    //String title = activityInfo.loadLabel(getPackageManager()).toString();
    int descriptionResId = activityInfo.descriptionRes;
    if (descriptionResId != 0) {
        toolbar.setSubtitle(Utilities.fromHtml(getString(descriptionResId)));
    }
}
catch(Exception e) {
    Log.e(LOG_TAG, "Could not get description/subtitle from manifest", e);
}

This way you only need to specify the title string once, and you get to specify the subtitle right alongside it.

What are these new categories of expressions?

The FCD (n3092) has an excellent description:

— An lvalue (so called, historically, because lvalues could appear on the left-hand side of an assignment expression) designates a function or an object. [ Example: If E is an expression of pointer type, then *E is an lvalue expression referring to the object or function to which E points. As another example, the result of calling a function whose return type is an lvalue reference is an lvalue. —end example ]

— An xvalue (an “eXpiring” value) also refers to an object, usually near the end of its lifetime (so that its resources may be moved, for example). An xvalue is the result of certain kinds of expressions involving rvalue references (8.3.2). [ Example: The result of calling a function whose return type is an rvalue reference is an xvalue. —end example ]

— A glvalue (“generalized” lvalue) is an lvalue or an xvalue.

— An rvalue (so called, historically, because rvalues could appear on the right-hand side of an assignment expressions) is an xvalue, a temporary object (12.2) or subobject thereof, or a value that is not associated with an object.

— A prvalue (“pure” rvalue) is an rvalue that is not an xvalue. [ Example: The result of calling a function whose return type is not a reference is a prvalue. The value of a literal such as 12, 7.3e5, or true is also a prvalue. —end example ]

Every expression belongs to exactly one of the fundamental classifications in this taxonomy: lvalue, xvalue, or prvalue. This property of an expression is called its value category. [ Note: The discussion of each built-in operator in Clause 5 indicates the category of the value it yields and the value categories of the operands it expects. For example, the built-in assignment operators expect that the left operand is an lvalue and that the right operand is a prvalue and yield an lvalue as the result. User-defined operators are functions, and the categories of values they expect and yield are determined by their parameter and return types. —end note

I suggest you read the entire section 3.10 Lvalues and rvalues though.

How do these new categories relate to the existing rvalue and lvalue categories?

Again:

Are the rvalue and lvalue categories in C++0x the same as they are in C++03?

The semantics of rvalues has evolved particularly with the introduction of move semantics.

Why are these new categories needed?

So that move construction/assignment could be defined and supported.

The answers on here are specific to using the custom UI Editor. I spent some time creating the interface without that wonderful program, so I am documenting the solution here to help anyone else decide if they need that custom UI editor or not.

I came across the following microsoft help webpage - https://msdn.microsoft.com/en-us/library/office/ff861787.aspx. This shows how to set up the interface manually, but I had some trouble when pointing to my custom add-in code.

To get the buttons to work with your custom macros, setup the macro in your .xlam subs to be called as described in this SO answer - Calling an excel macro from the ribbon. Basically, you'll need to add that "control As IRibbonControl" paramter to any module pointed from your ribbon xml. Also, your ribbon xml should have the onAction="myaddin!mymodule.mysub" syntax to properly call any modules loaded by the add in.

Using those instructions I was able to create an excel add in (.xlam file) that has a custom tab loaded when my VBA gets loaded into Excel along with the add in. The buttons execute code from the add in and the custom tab uninstalls when I remove the add in.

In python notebooks I often want to filter out 'dangling' numpy.ndarray's, in particular the ones that are stored in _1, _2, etc that were never really meant to stay alive.

I use this code to get a listing of all of them and their size.

Not sure if locals() or globals() is better here.

import sys
import numpy
from humanize import naturalsize

for size, name in sorted(
    (value.nbytes, name)
    for name, value in locals().items()
    if isinstance(value, numpy.ndarray)):
  print("{:>30}: {:>8}".format(name, naturalsize(size)))

append( ) function and spread operator

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

package main

import (
    "fmt"
)

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

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

Why to complicate a situation if you can just write like it? (yes -> low cohesion, hardcoded -> but it is a example and unfortunately with imperative way). For additional info read code example at below ;))

package timer.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.time.Duration;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.util.concurrent.*;

public class TestKitTimerWithExecuterService {

    private static final Logger log = LoggerFactory.getLogger(TestKitTimerWithExecuterService.class);

    private static final ScheduledExecutorService executorService 
= Executors.newSingleThreadScheduledExecutor();// equal to => newScheduledThreadPool(1)/ Executor service with one Thread

    private static ScheduledFuture<?> future; // why? because scheduleAtFixedRate will return you it and you can act how you like ;)



    public static void main(String args[]){

        log.info("main thread start");

        Runnable task = () -> log.info("******** Task running ********");

        LocalDateTime now = LocalDateTime.now();

        LocalDateTime whenToStart = LocalDate.now().atTime(20, 11); // hour, minute

        Duration duration = Duration.between(now, whenToStart);

        log.info("WhenToStart : {}, Now : {}, Duration/difference in second : {}",whenToStart, now, duration.getSeconds());

        future = executorService.scheduleAtFixedRate(task
                , duration.getSeconds()    //  difference in second - when to start a job
                ,2                         // period
                , TimeUnit.SECONDS);

        try {
            TimeUnit.MINUTES.sleep(2);  // DanDig imitation of reality
            cancelExecutor();    // after canceling Executor it will never run your job again
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        log.info("main thread end");
    }




    public static void cancelExecutor(){

        future.cancel(true);
        executorService.shutdown();

        log.info("Executor service goes to shut down");
    }

}

You should be able to get the text using getText() (for the option element you got using getFirstSelectedOption()):

Select select = new Select(driver.findElement(By.xpath("//select")));
WebElement option = select.getFirstSelectedOption();
String defaultItem = option.getText();
System.out.println(defaultItem );

I face with the same issue. I deleted the local repository and relaunched the ID. It worked fine .

An easy way to do this is to map the variable and return each Character as a String:

let someText = "hello"

let array = someText.map({ String($0) }) // [String]

The output should be ["h", "e", "l", "l", "o"].

SELECT COUNT(*)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC;

EDIT (if you just want the gids):

SELECT MIN(gid)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC

/Images/myImage.png

this has to be in root of your domain/subdomain

http://website.to/Images/myImage.png

and it will work

However, I think it would work like this, too

• images
  • yourimage.png
• styles
  • style.css

style.css:

body{
    background: url(../images/yourimage.png);
}

the -client and -server systems are different binaries. They are essentially two different compilers (JITs) interfacing to the same runtime system. The client system is optimal for applications which need fast startup times or small footprints, the server system is optimal for applications where the overall performance is most important. In general the client system is better suited for interactive applications such as GUIs

We run the following code with both switches:

package com.blogspot.sdoulger;

public class LoopTest {
    public LoopTest() {
        super();
    }

    public static void main(String[] args) {
        long start = System.currentTimeMillis();
        spendTime();
        long end = System.currentTimeMillis();
        System.out.println("Time spent: "+ (end-start));

        LoopTest loopTest = new LoopTest();
    }

    private static void spendTime() {
        for (int i =500000000;i>0;i--) {
        }
    }
}

Note: The code is been compiled only once! The classes are the same in both runs!

With -client:
java.exe -client -classpath C:\mywork\classes com.blogspot.sdoulger.LoopTest
Time spent: 766

With -server:
java.exe -server -classpath C:\mywork\classes com.blogspot.sdoulger.LoopTest
Time spent: 0

It seems that the more aggressive optimazation of the server system, remove the loop as it understands that it does not perform any action!

Reference

You should create a variable of the type SelectionneNonSelectionne.

struct SelectionneNonSelectionne var;

After that pass that variable to the function like

characterSelection(screen, var);

The error is caused since you are passing the type name SelectionneNonSelectionne

For Multiple columns you can use code similar to one given below.I was just going through this and found answer to check multiple columns in Datatable.

 private bool IsAllColumnExist(DataTable tableNameToCheck, List<string> columnsNames)
    {
        bool iscolumnExist = true;
        try
        {
            if (null != tableNameToCheck && tableNameToCheck.Columns != null)
            {
                foreach (string columnName in columnsNames)
                {
                    if (!tableNameToCheck.Columns.Contains(columnName))
                    {
                        iscolumnExist = false;
                        break;
                    }
                }
            }
            else
            {
                iscolumnExist = false;
            }
        }            
        catch (Exception ex)
        {

        }
        return iscolumnExist;
    }

You can have a regular Python module, say config.py, like this:

truck = dict(
    color = 'blue',
    brand = 'ford',
)
city = 'new york'
cabriolet = dict(
    color = 'black',
    engine = dict(
        cylinders = 8,
        placement = 'mid',
    ),
    doors = 2,
)

and use it like this:

import config
print(config.truck['color'])  

You can try this:

regex = [\W_]

It will definitely help you.

I don't know about targeting iOS as a whole, but to target iOS Safari specifically:

@supports (-webkit-touch-callout: none) {
   /* CSS specific to iOS devices */ 
}

@supports not (-webkit-touch-callout: none) {
   /* CSS for other than iOS devices */ 
}

Apparently as of iOS 13 -webkit-overflow-scrolling no longer responds to @supports, but -webkit-touch-callout still does. Of course that could change in the future...

Nor Kelsey, nor Brendan solutions does not works for me in Visual Studio 2015 Community.

Here is my brief steps how to create service with installer:

1. Run Visual Studio, Go to File->New->Project
2. Select .NET Framework 4, in 'Search Installed Templates' type 'Service'
3. Select 'Windows Service'. Type Name and Location. Press OK.
4. Double click Service1.cs, right click in designer and select 'Add Installer'
5. Double click ProjectInstaller.cs. For serviceProcessInstaller1 open Properties tab and change 'Account' property value to 'LocalService'. For serviceInstaller1 change 'ServiceName' and set 'StartType' to 'Automatic'.

6. Double click serviceInstaller1. Visual Studio creates serviceInstaller1_AfterInstall event. Write code:

   private void serviceInstaller1_AfterInstall(object sender, InstallEventArgs e)
   {
       using (System.ServiceProcess.ServiceController sc = new 
       System.ServiceProcess.ServiceController(serviceInstaller1.ServiceName))
       {
           sc.Start();
       }
   }
   

7. Build solution. Right click on project and select 'Open Folder in File Explorer'. Go to bin\Debug.

8. Create install.bat with below script:

   :::::::::::::::::::::::::::::::::::::::::
   :: Automatically check & get admin rights
   :::::::::::::::::::::::::::::::::::::::::
   @echo off
   CLS 
   ECHO.
   ECHO =============================
   ECHO Running Admin shell
   ECHO =============================
   
   :checkPrivileges 
   NET FILE 1>NUL 2>NUL
   if '%errorlevel%' == '0' ( goto gotPrivileges ) else ( goto getPrivileges ) 
   
   :getPrivileges 
   if '%1'=='ELEV' (shift & goto gotPrivileges)  
   ECHO. 
   ECHO **************************************
   ECHO Invoking UAC for Privilege Escalation 
   ECHO **************************************
   
   setlocal DisableDelayedExpansion
   set "batchPath=%~0"
   setlocal EnableDelayedExpansion
   ECHO Set UAC = CreateObject^("Shell.Application"^) > "%temp%\OEgetPrivileges.vbs" 
   ECHO UAC.ShellExecute "!batchPath!", "ELEV", "", "runas", 1 >> "%temp%\OEgetPrivileges.vbs" 
   "%temp%\OEgetPrivileges.vbs" 
   exit /B 
   
   :gotPrivileges 
   ::::::::::::::::::::::::::::
   :START
   ::::::::::::::::::::::::::::
   setlocal & pushd .
   
   cd /d %~dp0
   %windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil /i "WindowsService1.exe"
   pause
   

9. Create uninstall.bat file (change in pen-ult line /i to /u)
10. To install and start service run install.bat, to stop and uninstall run uninstall.bat

Here it is, You have to follow write a few methods here. #Swift 5

func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
    
    let header = view as? UITableViewHeaderFooterView
    header?.textLabel?.font = UIFont.init(name: "Montserrat-Regular", size: 14)
    header?.textLabel?.textColor = .greyishBrown
}

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    
    return 26
}

Have a good luck

More simple way with es6 style.

const indexOfAll = (arr, val) => arr.reduce((acc, el, i) => (el === val ? [...acc, i] : acc), []);


//Examples:
var cars = ["Nano", "Volvo", "BMW", "Nano", "VW", "Nano"];
indexOfAll(cars, "Nano"); //[0, 3, 5]
indexOfAll([1, 2, 3, 1, 2, 3], 1); // [0,3]
indexOfAll([1, 2, 3], 4); // []

function ngController($scope,$filter){
    $scope.name = "aaaa";
    $scope.age = "32";

     $scope.result = function(){
        return $filter('lowercase')($scope.name);
    };
}

The controller method 2nd argument name should be "$filter" then only the filter functionality will work with this example. In this example i have used the "lowercase" Filter.

This is more understandable:

git checkout 56e05fced -- .
git add .
git commit -m 'Revert to 56e05fced'

And to prove that it worked:

git diff 56e05fced

In order for this to work that Javascript must be placed within a Razor view so that the line

@Url.Action("Action","Controller")

is parsed by Razor and the real value replaced.

If you don't want to move your Javascript into your View you could look at creating a settings object in the view and then referencing that from your Javascript file.

e.g.

var MyAppUrlSettings = {
    MyUsefulUrl : '@Url.Action("Action","Controller")'
}

and in your .js file

$.ajax({
 type: "POST",
 url: MyAppUrlSettings.MyUsefulUrl,
 data: "{queryString:'" + searchVal + "'}",
 contentType: "application/json; charset=utf-8",
 dataType: "html",
 success: function (data) {
 alert("here" + data.d.toString());
});

or alternatively look at levering the framework's built in Ajax methods within the HtmlHelpers which allow you to achieve the same without "polluting" your Views with JS code.

Windows solution: Assuming all files contained in sub-directory 'src', and you want to compile them to 'bin'.

for /r src %i in (*.java) do javac %i -sourcepath src -d bin

If src contains a .java file immediately below it then this is faster

javac src\\*.java -d bin

TL:DR; return promises from you actions only when necessary, but DRY chaining the same actions.

For a long time I also though that returning actions contradicts the Vuex cycle of uni-directional data flow.

But, there are EDGE CASES where returning a promise from your actions might be "necessary".

Imagine a situation where an action can be triggered from 2 different components, and each handles the failure case differently. In that case, one would need to pass the caller component as a parameter to set different flags in the store.

Dumb example

Page where the user can edit the username in navbar and in /profile page (which contains the navbar). Both trigger an action "change username", which is asynchronous. If the promise fails, the page should only display an error in the component the user was trying to change the username from.

Of course it is a dumb example, but I don't see a way to solve this issue without duplicating code and making the same call in 2 different actions.

var isImgLoaded = function(imgSelector){
  return $(imgSelector).prop("complete") && $(imgSelector).prop("naturalWidth") !== 0;
}

// Or As a Plugin

    $.fn.extend({
      isLoaded: function(){
        return this.prop("complete") && this.prop("naturalWidth") !== 0;
      }
    })

// $(".myImage").isLoaded() 

Historically, it's been impossible to make these things disappear as they are user settings and not considered part of the page you have control over.

However, as of 2017, the @page at-rule has been standardized, which can be used to hide the page title and date in modern browsers:

@page { size: auto;  margin: 0mm; }

Print headers/footers and print margins

When printing Web documents, margins are set in the browser's Page Setup (or Print Setup) dialog box. These margin settings, although set within the browser, are controlled at the operating system/printer driver level and are not controllable at the HTML/CSS/DOM level. (For CSS-controlled printed page headers and footers see Printing Headers .)

The settings must be big enough to encompass the printer's physical non-printing areas. Further, they must be big enough to encompass the header and footer that the browser is usually configured to print (typically the page title, page number, URL and date). Note that these headers and footers, although specified by the browser and usually configurable through user preferences, are not part of the Web page itself and therefore are not controllable by CSS. In CSS terms, they fall outside the Page Box CSS2.1 Section 13.2.

... i.e. setting a margin of 0 hides the page title because the title is printed in the margin.

1. First activate your conda environment (the one u want to export/backup)

conda activate myEnv

2. Export all packages to a file (myEnvBkp.txt)

conda list --explicit > myEnvBkp.txt

3. Restore/import the environment:

conda create --name myEnvRestored --file myEnvBkp.txt

You can use a bind variable at the SQLPlus level to do this. Of course you have little control over the formatting of the output.

VAR x REFCURSOR;
EXEC GetGrantListByPI(args, :x);
PRINT x;

I think of %w() as a "word array" - the elements are delimited by spaces and it returns an array of strings.

There are other % literals:

• %r() is another way to write a regular expression.
• %q() is another way to write a single-quoted string (and can be multi-line, which is useful)
• %Q() gives a double-quoted string
• %x() is a shell command
• %i() gives an array of symbols (Ruby >= 2.0.0)
• %s() turns foo into a symbol (:foo)

I don't know any others, but there may be some lurking around in there...

From http://www.w3.org/International/articles/language-tags/

"Language tag syntax is defined by the IETF's BCP 47. BCP stands for 'Best Current Practice', and is a persistent name for a series of RFCs whose numbers change as they are updated. The latest RFC describing language tag syntax is RFC 5646, Tags for the Identification of Languages, and it obsoletes the older RFCs 4646, 3066 and 1766.

You used to find subtags by consulting the lists of codes in various ISO standards, but now you can find all subtags in the IANA Language Subtag Registry."

AFAIK most locale-aware applications (that are written by professionals) abide by this standard. It isn't just something somebody threw together and that different people interpret differently.

I'd strongly suggest you investigate the internationalization features of your particular development language, as you'll probably end up reinventing the wheel if you don't.

Because a dictionary is a single value. You need to use keyword expansion if you want to pass it as a group of keyword arguments.

I had the same issuse after following this: PostgreSQL setup for Rails development in Ubuntu 12.04

I tried the other answers but all I had to do was in: "config/database.yml"

development:
  adapter: postgresql
  encoding: unicode
  database: (appname)_development
  pool: 5
  username: (username you granted appname database priviledges to)
  password:

For xml parsing of an inputstream you can do:

// the SAX way:
XMLReader myReader = XMLReaderFactory.createXMLReader();
myReader.setContentHandler(handler);
myReader.parse(new InputSource(new URL(url).openStream()));

// or if you prefer DOM:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new URL(url).openStream());

But to communicate over http from server to client I prefer using hessian library or springs http invoker lib

                ((TextView) tabViewChild).setTextSize(15);

            }
        }
    }

This code is works for me using tablayout. It will change size of fonts and also change font style.

This will also help you guys please check this link

This code works for Tablayout change text color,type face (font style) and also text size.

Simply do the following:

1. Open your .sql file with Notepad or Notepad ++

2. Find InnoDB and Replace all (around 87) with MyISAM

3. Save and now you can import your database with out error.

The definition of the perfmon counters has been broken since the beginning and for some reason appears to be too hard to correct.

A good overview of Windows memory management is available in the video "Mysteries of Memory Management Revealed" on MSDN: It covers more topics than needed to track memory leaks (eg working set management) but gives enough detail in the relevant topics.

To give you a hint of the problem with the perfmon counter descriptions, here is the inside story about private bytes from "Private Bytes Performance Counter -- Beware!" on MSDN:

Q: When is a Private Byte not a Private Byte?

A: When it isn't resident.

The Private Bytes counter reports the commit charge of the process. That is to say, the amount of space that has been allocated in the swap file to hold the contents of the private memory in the event that it is swapped out. Note: I'm avoiding the word "reserved" because of possible confusion with virtual memory in the reserved state which is not committed.

From "Performance Planning" on MSDN:

3.3 Private Bytes

3.3.1 Description

Private memory, is defined as memory allocated for a process which cannot be shared by other processes. This memory is more expensive than shared memory when multiple such processes execute on a machine. Private memory in (traditional) unmanaged dlls usually constitutes of C++ statics and is of the order of 5% of the total working set of the dll.

Here is a solution that works for me. It involves radio button binding--but not binding to business data, but instead, binding to the state of the radio button. It is probably NOT the best solution for new projects, but is appropriate for my project. My project has a ton of existing code written in a different technology which I am porting to Angular. The old code follows a pattern in which the code is very interested in examining each radio button to see if it is the selected one. The solution is a variation of the click handler solutions, some of which have already been mentioned on Stack Overflow. The value added of this solution may be:

1. Works with the pattern of old code that I have to work with.
2. I created a helper class to try to reduce the number of "if" statements in the click handler, and to handle any group of radio buttons.

This solution involves

1. Using a different model for each radio button.
2. Setting the "checked" attribute with the radio button's model.
3. Passing the model of the clicked radio button to the helper class.
4. The helper class makes sure the models are up-to-date.
5. At "submit time" this allows the old code to examine the state of the radio buttons to see which one is selected by examining the models.

Example:

<input type="radio"
    [checked]="maleRadioButtonModel.selected"
    (click)="radioButtonGroupList.selectButton(maleRadioButtonModel)"

...

 <input type="radio"
    [checked]="femaleRadioButtonModel.selected"
    (click)="radioButtonGroupList.selectButton(femaleRadioButtonModel)"

...

When the user clicks a radio button, the selectButton method of the helper class gets invoked. It is passed the model for the radio button that got clicked. The helper class sets the boolean "selected" field of the passed in model to true, and sets the "selected" field of all the other radio button models to false.

During initialization the component must construct an instance of the helper class with a list of all radio button models in the group. In the example, "radioButtonGroupList" would be an instance of the helper class whose code is:

 import {UIButtonControlModel} from "./ui-button-control.model";


 export class UIRadioButtonGroupListModel {

  private readonly buttonList : UIButtonControlModel[];
  private readonly debugName : string;


  constructor(buttonList : UIButtonControlModel[], debugName : string) {

    this.buttonList = buttonList;
    this.debugName = debugName;

    if (this.buttonList == null) {
      throw new Error("null buttonList");
    }

    if (this.buttonList.length < 2) {
      throw new Error("buttonList has less than 2 elements")
    }
  }



  public selectButton(buttonToSelect : UIButtonControlModel) : void {

    let foundButton : boolean = false;
    for(let i = 0; i < this.buttonList.length; i++) {
      let oneButton : UIButtonControlModel = this.buttonList[i];
      if (oneButton === buttonToSelect) {
        oneButton.selected = true;
        foundButton = true;
      } else {
        oneButton.selected = false;
      }

    }

    if (! foundButton) {
      throw new Error("button not found in buttonList");
    }
  }
}

You can write that block of code in your application web.config file.

<httpRuntime maxRequestLength="2048576000" />
<sessionState timeout="3600"  />

By writing that code you can upload a larger file than now

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

You need a whole input match here.

System.out.println(test.matches("^(http|https|ftp)://.*$")); 

Edit:(Based on @davidchambers's comment)

System.out.println(test.matches("^(https?|ftp)://.*$")); 

Just for fun, here is a solution using ed which does not have the problem of not working on an empty file. You can put it into a shell script just like any other answer to this question.

ed Test <<EOF
a

.
0i
<added text>
.
1,+1 j
$ g/^$/d
wq
EOF

The above script adds the text to insert to the first line, and then joins the first and second line. To avoid ed exiting on error with an invalid join, it first creates a blank line at the end of the file and remove it later if it still exists.

Limitations: This script does not work if <added text> is exactly equal to a single period.

Implementation with low memory and fastest.

private Byte  BitReverse(Byte bData)
    {
        Byte[] lookup = { 0, 8,  4, 12, 
                          2, 10, 6, 14 , 
                          1, 9,  5, 13,
                          3, 11, 7, 15 };
        Byte ret_val = (Byte)(((lookup[(bData & 0x0F)]) << 4) + lookup[((bData & 0xF0) >> 4)]);
        return ret_val;
    }

I'm sure this isn't as fast as the solutions using Pandas or Numpy operations, but if you don't want to rewrite your function you can use map. Using the original example data -

import pandas as pd

df = pd.DataFrame({'ID':['1','2','3'], 'col_1': [0,2,3], 'col_2':[1,4,5]})
mylist = ['a','b','c','d','e','f']

def get_sublist(sta,end):
    return mylist[sta:end+1]

df['col_3'] = list(map(get_sublist,df['col_1'],df['col_2']))
#In Python 2 don't convert above to list

We could pass as many arguments as we wanted into the function this way. The output is what we wanted

ID  col_1  col_2      col_3
0  1      0      1     [a, b]
1  2      2      4  [c, d, e]
2  3      3      5  [d, e, f]

Granted, there are definitely different thinking, in my world, I cannot enforce "Never pass a null" because I am dealing with uncontrollable third parties like API callers, database records, former programmers etc... so I am paranoid and defensive in approaches. Since you are on Java8 or later there is a bit cleaner approach than an if block.

public String foo(@Nullable String mayBeNothing) {
   return Optional.ofNullable(mayBeNothing).orElse("Really Nothing");
}

You can also throw some exception in there by swapping .orElse to orElseThrow(() -> new Exception("Dont' send a null")).

If you don't want to use @Nullable, which adds nothing functionally, why not just name the parameter with mayBe... so your intention is clear.

Even though this post is outdated, collection.remove is deprecated! collection.delete_one should be used instead!

flush() will synchronize your database with the current state of object/objects held in the memory but it does not commit the transaction. So, if you get any exception after flush() is called, then the transaction will be rolled back. You can synchronize your database with small chunks of data using flush() instead of committing a large data at once using commit() and face the risk of getting an OutOfMemoryException.

commit() will make data stored in the database permanent. There is no way you can rollback your transaction once the commit() succeeds.

I could be wrong, but I'm pretty sure that the "interrupt kernel" button just sends a SIGINT signal to the code that you're currently running (this idea is supported by Fernando's comment here), which is the same thing that hitting CTRL+C would do. Some processes within python handle SIGINTs more abruptly than others.

If you desperately need to stop something that is running in iPython Notebook and you started iPython Notebook from a terminal, you can hit CTRL+C twice in that terminal to interrupt the entire iPython Notebook server. This will stop iPython Notebook alltogether, which means it won't be possible to restart or save your work, so this is obviously not a great solution (you need to hit CTRL+C twice because it's a safety feature so that people don't do it by accident). In case of emergency, however, it generally kills the process more quickly than the "interrupt kernel" button.

Taking Vaclav's answer and making it more Angular-like:

angular.module('myApp').filter('total', ['$parse', function ($parse) {
    return function (input, property) {
        var i = input instanceof Array ? input.length : 0,
            p = $parse(property);

        if (typeof property === 'undefined' || i === 0) {
            return i;
        } else if (isNaN(p(input[0]))) {
            throw 'filter total can count only numeric values';
        } else {
            var total = 0;
            while (i--)
                total += p(input[i]);
            return total;
        }
    };
}]);

This gives you the benefit of even accessing nested and array data:

{{data | total:'values[0].value'}}
