Expanded from @SeaBrightSystems answer, you could try this:

$s1 = "textasstringwoohoo";
$arr = str_split($s1); //$arr now has character array

You need to run this command in the top-level directory of a Selenium SVN repository checkout.

To find files in immediate subdirectories:

configfiles = glob.glob(r'C:\Users\sam\Desktop\*\*.txt')

For a recursive version that traverse all subdirectories, you could use ** and pass recursive=True since Python 3.5:

configfiles = glob.glob(r'C:\Users\sam\Desktop\**\*.txt', recursive=True)

Both function calls return lists. You could use glob.iglob() to return paths one by one. Or use pathlib:

from pathlib import Path

path = Path(r'C:\Users\sam\Desktop')
txt_files_only_subdirs = path.glob('*/*.txt')
txt_files_all_recursively = path.rglob('*.txt') # including the current dir

Both methods return iterators (you can get paths one by one).

• A Callable needs to implement call() method while a Runnable needs to implement run() method.
• A Callable can return a value but a Runnable cannot.
• A Callable can throw checked exception but a Runnable cannot.

• A Callable can be used with ExecutorService#invokeXXX(Collection<? extends Callable<T>> tasks) methods but a Runnable cannot be.

  public interface Runnable {
      void run();
  }
  
  public interface Callable<V> {
      V call() throws Exception;
  }
  

This seems a weird request and deserves a weird solution:

string[] sizes = new string[] { "105", "101", "102", "103", "90" };

foreach (var size in sizes.OrderBy(x => {
    double sum = 0;
    int position = 0;
    foreach (char c in x.ToCharArray().Reverse()) {
        sum += (c - 48) * (int)(Math.Pow(10,position));
        position++;
    }
    return sum;
}))

{
    Console.WriteLine(size);
}

You can also try /etc/redhat-release or /etc/fedora-release:

cat /etc/fedora-release 
Fedora release 7 (Moonshine)

I know, this is not really a solution for your question, because you ask for

display + opacity

My approach solves a more general question, but maybe this was the background problem that should be solved by using display in combination with opacity.

My desire was to get the Element out of the way when it is not visible. This solution does exactly that: It moves the element out of the away, and this can be used for transition:

.child {
  left: -2000px;
  opacity: 0;
  visibility: hidden;
  transition: left 0s 0.8s, visibility 0s 0.8s, opacity 0.8s;
}

.parent:hover .child {
  left: 0;
  opacity: 1;
  visibility: visible;
  transition: left 0s, visibility 0s, opacity 0.8s;
}

This code does not contain any browser prefixes or backward compatibility hacks. It just illustrates the concept how the element is moved away as it is not needed any more.

The interesting part are the two different transition definitions. When the mouse-pointer is hovering the .parent element the .child element needs to be put in place immediately and then the opacity will be changed:

transition: left 0s, visibility 0s, opacity 0.8s;

When there is no hover, or the mouse-pointer was moved off the element, one has to wait until the opacity change has finished before the element can be moved off screen:

transition: left 0s 0.8s, visibility 0s 0.8s, opacity 0.8s;

Moving the object away will be a viable alternative in a case where setting display:none would not break the layout.

I hope I hit the nail on the head for this question although I did not answer it.

If a user has never set an alarm on their phone, the TYPE_ALARM can return null. You can account for this with:

Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

if(alert == null){
    // alert is null, using backup
    alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    // I can't see this ever being null (as always have a default notification)
    // but just incase
    if(alert == null) {  
        // alert backup is null, using 2nd backup
        alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);                
    }
}

Money Shot

Here's a compact version of using applymap with a straightforward lambda expression to call strip only when the value is of a string type:

df.applymap(lambda x: x.strip() if isinstance(x, str) else x)

Full Example

A more complete example:

import pandas as pd


def trim_all_columns(df):
    """
    Trim whitespace from ends of each value across all series in dataframe
    """
    trim_strings = lambda x: x.strip() if isinstance(x, str) else x
    return df.applymap(trim_strings)


# simple example of trimming whitespace from data elements
df = pd.DataFrame([['  a  ', 10], ['  c  ', 5]])
df = trim_all_columns(df)
print(df)


>>>
   0   1
0  a  10
1  c   5

Working Example

Here's a working example hosted by trinket: https://trinket.io/python3/e6ab7fb4ab

To Change the format of Date you have Require both format look below.

 String stringdate1 = "28/04/2010";  

 try {

     SimpleDateFormat format1 = new SimpleDateFormat("dd/MM/yyyy");
     Date date1 = format1.parse()
     SimpleDateFormat format2 = new SimpleDateFormat("yyyy/MM/dd");

     String stringdate2 = format2.format(date1);
    } catch (ParseException e) {
   e.printStackTrace();
}

here stringdate2 have date format of yyyy/MM/dd. and it contain 2010/04/28.

You may just call the onBackPressed()and if you want some activity to display after the back button you have mention the

Intent intent = new Intent(ResetPinActivity.this, MenuActivity.class);
    startActivity(intent);
    finish();

that worked for me.

Here is a simple example for others visiting this old post, but is confused by the example in the question and the other answer:

Delivery -> Package (One -> Many)

CREATE TABLE Delivery(
    Id INT IDENTITY PRIMARY KEY,
    NoteNumber NVARCHAR(255) NOT NULL
)

CREATE TABLE Package(
    Id INT IDENTITY PRIMARY KEY,
    Status INT NOT NULL DEFAULT 0,
    Delivery_Id INT NOT NULL,
    CONSTRAINT FK_Package_Delivery_Id FOREIGN KEY (Delivery_Id) REFERENCES Delivery (Id) ON DELETE CASCADE
)

The entry with the foreign key Delivery_Id (Package) is deleted with the referenced entity in the FK relationship (Delivery).

So when a Delivery is deleted the Packages referencing it will also be deleted. If a Package is deleted nothing happens to any deliveries.

let dateTimeStamp = NSDate(timeIntervalSince1970:Double(currentTimeInMiliseconds())/1000)  //UTC time  //YOUR currentTimeInMiliseconds METHOD
let dateFormatter = NSDateFormatter()
dateFormatter.timeZone = NSTimeZone.localTimeZone() 
dateFormatter.dateFormat = "yyyy-MM-dd"
dateFormatter.dateStyle = NSDateFormatterStyle.FullStyle
dateFormatter.timeStyle = NSDateFormatterStyle.ShortStyle


let strDateSelect = dateFormatter.stringFromDate(dateTimeStamp)
print("Local Time", strDateSelect) //Local time


let dateFormatter2 = NSDateFormatter()
dateFormatter2.timeZone = NSTimeZone(name: "UTC") as NSTimeZone!
dateFormatter2.dateFormat = "yyyy-MM-dd"

let date3 = dateFormatter.dateFromString(strDateSelect)
print("DATE",date3)

Jquery One-liners:

ES6 + jQuery:

$('#select').append([...Array(100).keys()].map((i,j) => `< option >${i}</option >`))

Lodash + jQuery:

$('#select').append(_.range(100).map(function(i,j){ return $('<option>',{text:i})}))

hey there for anyone who might be looking for solution like this.. i had issue with scaling inside WebView so best way to do is in your java.class where you set all for webView put this two line of code: (webViewSearch is name of my webView -->webViewSearch = (WebView) findViewById(R.id.id_webview_search);)

// force WebView to show content not zoomed---------------------------------------------------------
    webViewSearch.getSettings().setLoadWithOverviewMode(true);
    webViewSearch.getSettings().setUseWideViewPort(true);

I finally was able to figure out a simple solution without the @Query annotation.

List<People> findDistinctByNameNotIn(List<String> names);

Of course, I got the people object instead of only Strings. I can then do the change in java.

Try this out:

$url = 'http://techcrunch.com/startups/'; $url = str_replace(array('http://', 'https://'), '', $url); 

EDIT:

Or, a simple way to always remove the protocol:

$url = 'https://www.google.com/'; $url = preg_replace('@^.+?\:\/\/@', '', $url); 

I'm not sure that is the problem but what worked for me is calling mVideoView.start(); inside the mVideoView.setOnPreparedListener event callback.

For example:

Uri uriVideo = Uri.parse(<your link here>);

MediaController mediaController = new MediaController(mContext);
mediaController.setAnchorView(mVideoView);
mVideoView.setMediaController(mediaController);
mVideoView.setVideoURI(uriVideo);
mVideoView.requestFocus();

mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener()
{
     @Override
     public void onPrepared(MediaPlayer mp)
     {
          mVideoViewPeekItem.start();
     }
});

According to MDN, <input type="search" /> is currently supported in all modern browsers:

<input type="search" value="Clear this." />

However, if you want different behavior that is consistent across browsers here are some light-weight alternatives that only require JavaScript:

Option 1 - Always display the 'x': (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
  el.addEventListener('click', function(e) {
    e.target.previousElementSibling.value = '';
  });
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input > [data-clear-input] {
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Always display the 'x':</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Option 2 - Only display the 'x' when hovering over the field: (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
  el.addEventListener('click', function(e) {
    e.target.previousElementSibling.value = '';
  });
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input:hover > [data-clear-input] {
  display: block;
}
.clearable-input > [data-clear-input] {
  display: none;
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Only display the 'x' when hovering over the field:</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Option 3 - Only display the 'x' if the input element has a value: (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input'), function(el) {
  var input = el.querySelector('input');

  conditionallyHideClearIcon();
  input.addEventListener('input', conditionallyHideClearIcon);
  el.querySelector('[data-clear-input]').addEventListener('click', function(e) {
    input.value = '';
    conditionallyHideClearIcon();
  });

  function conditionallyHideClearIcon(e) {
    var target = (e && e.target) || input;
    target.nextElementSibling.style.display = target.value ? 'block' : 'none';
  }
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input >[data-clear-input] {
  display: none;
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Only display the 'x' if the `input` element has a value:</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

I had the same issue after migrating to a new environment and it was simply that the server didn't run mod_rewrite

a quick sudo a2enmod rewrite then sudo systemctl restart apache2

and problem solved...

Thanks @fanis who pointed that out in his comment on the question.

for (var i in a) {
   console.log(a[i],i)
}

I had a slightly different requirement, to parse an encoded dictionary/hashtable with escaped commas, like this:

"1=This is something, 2=This is something,,with an escaped comma, 3=This is something else"

I think this is an elegant solution, with a trick that avoids a lot of regex complexity:

if (string.IsNullOrEmpty(encodedValues))
{
    return null;
}
else
{
    var retVal = new Dictionary<int, string>();
    var reFields = new Regex(@"([0-9]+)\=(([A-Za-z0-9\s]|(,,))+),");
    foreach (Match match in reFields.Matches(encodedValues + ","))
    {
        var id = match.Groups[1].Value;
        var value = match.Groups[2].Value;
        retVal[int.Parse(id)] = value.Replace(",,", ",");
    }
    return retVal;
}

I think it can be adapted to the original question with an expression like @"([0-9]+),\s?" and parse on Groups[0].

I hope it's helpful to somebody and thanks for the tips on getting it close to there, especially Asaph!

If you inspect the User Agent StyleSheet of Chome, you'll find this

outline: -webkit-focus-ring-color auto 5px;

in short its outline property - make it None

that should remove the glow

During my current projects, I'm often passing rear parts of a path to a function and therefore use the Path module. To get the n-th part in reverse order, I'm using:

from typing import Union
from pathlib import Path

def get_single_subpath_part(base_dir: Union[Path, str], n:int) -> str:
    if n ==0:
        return Path(base_dir).name
    for _ in range(n):
        base_dir = Path(base_dir).parent
    return getattr(base_dir, "name")

path= "/folderA/folderB/folderC/folderD/"

# for getting the last part:
print(get_single_subpath_part(path, 0))
# yields "folderD"

# for the second last
print(get_single_subpath_part(path, 1))
#yields "folderC"

Furthermore, to pass the n-th part in reverse order of a path containing the remaining path, I use:

from typing import Union
from pathlib import Path

def get_n_last_subparts_path(base_dir: Union[Path, str], n:int) -> Path:
    return Path(*Path(base_dir).parts[-n-1:])

path= "/folderA/folderB/folderC/folderD/"

# for getting the last part:
print(get_n_last_subparts_path(path, 0))
# yields a `Path` object of "folderD"

# for second last and last part together 
print(get_n_last_subparts_path(path, 1))
# yields a `Path` object of "folderc/folderD"

Note that this function returns a Pathobject which can easily be converted to a string (e.g. str(path))

I can't say how much this might help you, but just found a solution to something similar problem which I faced. In the Pivot-

1. Right click and choose Pivot table options
2. Choose the display option
3. uncheck the first 'Show expand/Collapse buttons'
4. check the 'Classic PivotTable Layout(enables dragging of fields in the grid)
5. click ok.

This would refine the data. Then, I had just copy and pasted this data in a new tab wherein I had applied the filters to my Total column with values greater than certain percentage.

This did work in my case and hope it helps you too.

Here's what I ended up using.

I'm very new to AngularJS, so would love to see better / alternative solutions.

angular.module('formComponents', [])
    .directive('formInput', function() {
        return {
            restrict: 'E',
            scope: {},
            link: function(scope, element, attrs)
            {
                var type = attrs.type || 'text';
                var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
                var htmlText = '<div class="control-group">' +
                    '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                        '<div class="controls">' +
                        '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                        '</div>' +
                    '</div>';
                element.html(htmlText);
            }
        }
    })

Example usage:

<form-input label="Application Name" form-id="appName" required/></form-input>
<form-input type="email" label="Email address" form-id="emailAddress" required/></form-input>
<form-input type="password" label="Password" form-id="password" /></form-input>

You could skip all this and just put your data in a table. Then refer to the table and header and it will be completely dynamic. I know this is from 3 years ago but someone may still find this useful.

Example code:

Activesheet.Range("TableName[ColumnName]").Copy

You can also use :

activesheet.listobjects("TableName[ColumnName]").Copy

You can even use this reference system in worksheet formulas as well. Its very dynamic.

Hope this helps!

Something along these lines worked for me. Starting with a bit of code taken from Joe, this method modifies the window width to automatically fit a legend to the right of the figure.

import matplotlib.pyplot as plt
import numpy as np

plt.ion()

x = np.arange(10)

fig = plt.figure()
ax = plt.subplot(111)

for i in xrange(5):
    ax.plot(x, i * x, label='$y = %ix$'%i)

# Put a legend to the right of the current axis
leg = ax.legend(loc='center left', bbox_to_anchor=(1, 0.5))

plt.draw()

# Get the ax dimensions.
box = ax.get_position()
xlocs = (box.x0,box.x1)
ylocs = (box.y0,box.y1)

# Get the figure size in inches and the dpi.
w, h = fig.get_size_inches()
dpi = fig.get_dpi()

# Get the legend size, calculate new window width and change the figure size.
legWidth = leg.get_window_extent().width
winWidthNew = w*dpi+legWidth
fig.set_size_inches(winWidthNew/dpi,h)

# Adjust the window size to fit the figure.
mgr = plt.get_current_fig_manager()
mgr.window.wm_geometry("%ix%i"%(winWidthNew,mgr.window.winfo_height()))

# Rescale the ax to keep its original size.
factor = w*dpi/winWidthNew
x0 = xlocs[0]*factor
x1 = xlocs[1]*factor
width = box.width*factor
ax.set_position([x0,ylocs[0],x1-x0,ylocs[1]-ylocs[0]])

plt.draw()

You have to check which Python you are using. I had the same problem because the Python I was using was not the same one that brew was using. In your command line:

1. which python
   output: /usr/bin/python
2. which brew
   output: /usr/local/bin/brew     //so they are different
3. cd /usr/local/lib/python2.7/site-packages
4. ls   //you can see PyQt4 and sip are here
5. Now you need to add usr/local/lib/python2.7/site-packages to your python path.
6. open ~/.bash_profile   //you will open your bash_profile file in your editor
7. Add 'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH' to your bash file and save it
8. Close your terminal and restart it to reload the shell
9. python
10. import PyQt4    // it is ok now

The simplest is to do a PivotChart. Select your array of dates (with a header) and create a new Pivot Chart (Insert / PivotChart / Ok) Then on the field list window, drag and drop the date column in the Axis list first and then in the value list first.

Step 1:

Step 2:

 SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE') 
 and owner = 'Schema_name' order by object_name

here 'Schema_name' is a name of schema, example i have a schema named PMIS, so the example will be

SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE') 
and owner = 'PMIS' order by object_name

Ref: https://www.plsql.co/list-all-procedures-from-a-schema-of-oracle-database.html

The error occurs when:

$a = array(); 
$a['text1'] = array();
$a['text1']['text2'] = 'sometext';

Then

echo $a['text1']['text2'];     //Error!!

Solution

$b = $a['text1'];
echo $b['text2'];    // prints: sometext

If you're sure you restarted Apache after configuring php.ini, then you might be looking at the wrong php.ini file

Pull out ALL of your in-line CSS, and move it to the head. Then use classes on the cells so you can adjust everything as you like (don't use a name like "center" - you may change it to left 6 months from now...). The alignment answer is still the same - apply it to the <td> NOT the checkbox (that would just center your check :-) )

I'd start by not calling it list, since that's the name of the constructor for Python's built in list type.

But once you've renamed it to cities or something, you'd do:

print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])

Yes, you can use what's known as :nth-child selectors.

In this case you would use:

li:nth-child(3n) {
// Styling for every third element here.
}

:nth-child(3n):

3(0) = 0
3(1) = 3
3(2) = 6
3(3) = 9
3(4) = 12

:nth-child() is compatible in Chrome, Firefox, and IE9+.

For a work around to use :nth-child() amongst other pseudo-classes/attribute selectors in IE6 through to IE8, see this link.

You can use functors if you want a less generic and more precise control under the hood. Example with my win32 api to forward api message from a class to another class.

            typename std::map<UINT, IListener*>::iterator itEvt;
            if((itEvt = _listeners.find(uMsg)) == _listeners.end()) {
                return NULL;
            }
            return itEvt->second;
        }

        //Set a member function to receive message. 
        //Example Button->add<MyClass>(WM_COMMAND, this, &MyClass::myfunc);
        template <typename D> void add(UINT uMsg, D* instance, typename Listener<D>::WMFuncPtr wmFuncPtr) {
            _listeners[uMsg] = new Listener<D>(instance, wmFuncPtr);
        }

};

Usage principles

class Button {
    public:
    Dispatcher _dispatcher;
    //button window forward all received message to a listener
    LRESULT onMessage(HWND hWnd, UINT uMsg, WPARAM w, LPARAM l) {
        //to return a precise message like WM_CREATE, you have just
        //search it in the map.
        return _dispatcher[uMsg](hWnd, uMsg, w, l);
    }
};

class Myclass {
    Button _button;
    //the listener for Button messages
    LRESULT button_listener(HWND hWnd, UINT uMsg, WPARAM w, LPARAM l) {
        return 0;
    }

    //Register the listener for Button messages
    void initialize() {
        //now all message received from button are forwarded to button_listener function 
       _button._dispatcher.add(WM_CREATE, this, &Myclass::button_listener);
    }
};

Good luck and thank to all for sharing knowledge.

Note: This answer was for a previous version of this question where the question asker was trying to use JavaScript to apply css styles… which can simply be done with CSS.

A simple css-only solution.

For applying basic styles, CSS is simpler and more performant that JS solutions 99% of the time. (Though more modern CSS-in-JS solutions — eg. React Components, etc — are arguably more maintainable.)

Run this code snippet to see it in action…

.hover-button .hover-button--on,_x000D_
.hover-button:hover .hover-button--off {_x000D_
  display: none;_x000D_
}_x000D_
_x000D_
.hover-button:hover .hover-button--on {_x000D_
  display: inline;_x000D_
}

<button class='hover-button'>_x000D_
  <span class='hover-button--off'>Default</span>_x000D_
  <span class='hover-button--on'>Hover!</span>_x000D_
</button>

This is not to check for null, instead this will be helpful in converting an existing object to an empty object(fresh object). I dont know whether this is relevant or not, but I had such a requirement.

@SuppressWarnings({ "unchecked" })
static void emptyObject(Object obj) 
{
    Class c1 = obj.getClass();
    Field[] fields = c1.getDeclaredFields();

    for(Field field : fields)
    {
        try
        {
            if(field.getType().getCanonicalName() == "boolean")
            {
                field.set(obj, false);
            }
            else if(field.getType().getCanonicalName() == "char")
            {
                field.set(obj, '\u0000');
            }
            else if((field.getType().isPrimitive()))
            {
                field.set(obj, 0);
            }
            else
            {
                field.set(obj, null);
            }
        }
        catch(Exception ex)
        {

        }
    }
}

Try this:

preg_match("/net(.*)\.php$/","http://php.net/manual/en/function.preg-match.php", $matches);
echo $matches[1];
// prints /manual/en/function.preg-match

I solved this issue by:

1. Adding a custom header to the response:

   public ActionResult Index(){
       if (!HttpContext.User.Identity.IsAuthenticated)
       {
           HttpContext.Response.AddHeader("REQUIRES_AUTH","1");
       }
       return View();
   }
   

2. Binding a JavaScript function to the ajaxSuccess event and checking to see if the header exists:

   $(document).ajaxSuccess(function(event, request, settings) {
       if (request.getResponseHeader('REQUIRES_AUTH') === '1') {
          window.location = '/';
       }
   });
   

My solution is similar to molokoloco. Written as jQuery function:

$.fn.waitForImages = function (callback) {
    var $img = $('img', this),
        totalImg = $img.length;

    var waitImgLoad = function () {
        totalImg--;
        if (!totalImg) {
            callback();
        }
    };

    $img.each(function () {
        if (this.complete) { 
            waitImgLoad();
        }
    })

    $img.load(waitImgLoad)
        .error(waitImgLoad);
};

example:

<div>
    <img src="img1.png"/>
    <img src="img2.png"/>
</div>
<script>
    $('div').waitForImages(function () {
        console.log('img loaded');
    });
</script>

Necroing this question but there's an explanation that no-one seems to have considered.

STATISTICS - Statistics are not available or misleading

If all of the following are true:

1. The columns feedid and feedDate are likely to be highly correlated (e.g. a feed id is more specific than a feed date and the date parameter is redundant information).
2. There is no index with both columns as sequential columns.
3. There are no manually created statistics covering both these columns.

Then sql server may be incorrectly assuming that the columns are uncorrelated, leading to lower than expected cardinality estimates for applying both restrictions and a poor execution plan being selected. The fix in this case would be to create a statistics object linking the two columns, which is not an expensive operation.

For the creation add an empty object to the view.

return view('admin.profiles.create', ['profile' => new Profile()]);

Old function has a second parameter, default value, if you pass there the object's field, the input can be reused.

<input class="input" type="text" name="name" value="{{old('name', $profile->name)}}">

For the form action, you can use the correct endpoint.

<form action="{{ $profile->id == null ? '/admin/profiles' :  '/admin/profiles/' . $profile->id }} " method="POST">

And for the update you have to use PATCH method.

@isset($profile->id)
 {{ method_field('PATCH')}}
@endisset

Object initializers were introduced in C# 3.0, check which framework version you are targeting.

Overview of C# 3.0

If you have jQuery loaded on the page, you can execute the following javascript command:

"$('#" + element_id + "').click()"

Example using python executor:

driver.execute_script("$('#%s').click()" % element_id)

I know this question is pretty old now, but I thought you might have an easier time with ElementTree

from xml.etree import ElementTree as ET
import datetime

f = ET.XML(data)

for element in f:
    if element.tag == "currentTime":
        # Handle time data was pulled
        currentTime = datetime.datetime.strptime(element.text, "%Y-%m-%d %H:%M:%S")
    if element.tag == "cachedUntil":
        # Handle time until next allowed update
        cachedUntil = datetime.datetime.strptime(element.text, "%Y-%m-%d %H:%M:%S")
    if element.tag == "result":
        # Process list of skills
        pass

I know that's not super specific, but I just discovered it, and so far it's a lot easier to get my head around than the minidom (since so many nodes are essentially white space).

For instance, you have the tag name and the actual text together, just as you'd probably expect:

>>> element[0]
<Element currentTime at 40984d0>
>>> element[0].tag
'currentTime'
>>> element[0].text

varunl's currently accepted answer

 >>> l = [None] * 10
 >>> l
 [None, None, None, None, None, None, None, None, None, None]

Works well for non-reference types like numbers. Unfortunately if you want to create a list-of-lists you will run into referencing errors. Example in Python 2.7.6:

>>> a = [[]]*10
>>> a
[[], [], [], [], [], [], [], [], [], []]
>>> a[0].append(0)
>>> a
[[0], [0], [0], [0], [0], [0], [0], [0], [0], [0]]
>>> 

As you can see, each element is pointing to the same list object. To get around this, you can create a method that will initialize each position to a different object reference.

def init_list_of_objects(size):
    list_of_objects = list()
    for i in range(0,size):
        list_of_objects.append( list() ) #different object reference each time
    return list_of_objects


>>> a = init_list_of_objects(10)
>>> a
[[], [], [], [], [], [], [], [], [], []]
>>> a[0].append(0)
>>> a
[[0], [], [], [], [], [], [], [], [], []]
>>> 

There is likely a default, built-in python way of doing this (instead of writing a function), but I'm not sure what it is. Would be happy to be corrected!

Edit: It's [ [] for _ in range(10)]

Example :

>>> [ [random.random() for _ in range(2) ] for _ in range(5)]
>>> [[0.7528051908943816, 0.4325669600055032], [0.510983236521753, 0.7789949902294716], [0.09475179523690558, 0.30216475640534635], [0.3996890132468158, 0.6374322093017013], [0.3374204010027543, 0.4514925173253973]]

You can use time and subshell ():

time (
  for (( i=1; i<10000; i++ )); do
    echo 1 >/dev/null
  done
)

Or in same shell {}:

time {
  for (( i=1; i<10000; i++ )); do
    echo 1 >/dev/null
  done
}

A simple dictionary:

x = {'X':"yes", 'Y':"no", 'Z':"ok"}

To print a specific (key, value) pair in Python 3 (pair at index 1 in this example):

for e in range(len(x)):
    print(([x for x in x.keys()][e], [x for x in x.values()][e]))

Output:

('X', 'yes')
('Y', 'no')
('Z', 'ok')

Here is a one liner solution to print all pairs in a tuple:

print(tuple(([x for x in x.keys()][i], [x for x in x.values()][i]) for i in range(len(x))))

Output:

(('X', 'yes'), ('Y', 'no'), ('Z', 'ok'))

Here's what I do:

1. First of all I check whether NETWORK or GPS providers are enabled. Some may be disabled on the device, some may be disabled in application manifest. If any provider is enabled, I fetch cached last location for this provider and start location update listeners for this provider.
2. There is a method to determine whether a location is better than last received location as mentioned in link :- https://developer.android.com/guide/topics/location/strategies.html#BestEstimate
3. If I get update from location listener I check whether this location is better than previously received location. and If it is better than replace this location to previous best location(mFinalLocation).
4. There is also a handler(timer) for two minutes, which eventually stops the service and in onDestroy() method of service, stop listening for location updates for each of the provider.

Below is the code for service. You can run it based upon frequency of location update you need.

Most of the answers are/were valid. The new JAVA API modification for Date handling made sure that some earlier ambiguity in java date handling is reduced.

You will get a deprecated message for similar calls.

new Date() // deprecated

The above call had the developer to assume that a new Date object will give the Date object with current timestamp. This behavior is not consistent across other Java API classes.

The new way of doing this is using the Calendar Instance.

new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime()

Here too the naming convention is not perfect but this is much organised. For a person like me who has a hard time mugging up things but would never forget something if it sounds/appears logical, this is a good approach.

This is more synonymous to real life

1. We get a Calendar object and we look for the time in it. ( you must be wondering no body gets time from a Calendar, that is why I said it is not perfect.But that is a different topic altogether)
2. Then we want the date in a simple Text format so we use a SimpleDateFormat utility class which helps us in formatting the Date from Step 1. I have used yyyy, MM ,dd as parameters in the format. Supported date format parameters

One more way to do this is using Joda time API

new DateTime().toString("yyyy-MM-dd")

or the much obvious

new DateTime(Calendar.getInstance().getTime()).toString("yyyy-MM-dd")

both will return the same result.

svn add *

I can't find anything that deals with clock times exactly, so I'd just use some functions from package:lubridate and work with seconds-since-midnight:

require(lubridate)
clockS = function(t){hour(t)*3600+minute(t)*60+second(t)}
plot(clockS(times),val)

You might then want to look at some of the axis code to figure out how to label axes nicely.

Below are two simple query using which you can check index created on a table in Oracle.

select index_name
  from dba_indexes
 where table_name='&TABLE_NAME'
   and owner='&TABLE_OWNER';

select index_name 
  from user_indexes 
 where table_name='&TABLE_NAME';

Please check for more details and index size below. Index on a table and its size in Oracle

Here's what I do:

• In the interface, move the cursor to the method name. Press F4. => Type Hierarchy view appears
• In the lower part of the view, the method should already be selected. In its toolbar, click "Lock view and show members in hierarchy" (should be the leftmost toolbar icon).
• In the upper part of the view, you can browse through all implementations of the method.

The procedure isn't very quick, but it gives you a good overview.

There's a bit of confusion in your question:

• a Date datatype doesn't save the time zone component. This piece of information is truncated and lost forever when you insert a TIMESTAMP WITH TIME ZONE into a Date.
• When you want to display a date, either on screen or to send it to another system via a character API (XML, file...), you use the TO_CHAR function. In Oracle, a Date has no format: it is a point in time.
• Reciprocally, you would use TO_TIMESTAMP_TZ to convert a VARCHAR2 to a TIMESTAMP, but this won't convert a Date to a TIMESTAMP.
• You use FROM_TZ to add the time zone information to a TIMESTAMP (or a Date).
• In Oracle, CST is a time zone but CDT is not. CDT is a daylight saving information.
• To complicate things further, CST/CDT (-05:00) and CST/CST (-06:00) will have different values obviously, but the time zone CST will inherit the daylight saving information depending upon the date by default.

So your conversion may not be as simple as it looks.

Assuming that you want to convert a Date d that you know is valid at time zone CST/CST to the equivalent at time zone CST/CDT, you would use:

SQL> SELECT from_tz(d, '-06:00') initial_ts,
  2         from_tz(d, '-06:00') at time zone ('-05:00') converted_ts
  3    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  4                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  5            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
09/10/12 01:10:21,000000 -06:00 09/10/12 02:10:21,000000 -05:00

My default timestamp format has been used here. I can specify a format explicitely:

SQL> SELECT to_char(from_tz(d, '-06:00'),'yyyy-mm-dd hh24:mi:ss TZR') initial_ts,
  2         to_char(from_tz(d, '-06:00') at time zone ('-05:00'),
  3                 'yyyy-mm-dd hh24:mi:ss TZR') converted_ts
  4    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  5                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  6            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
2012-10-09 01:10:21 -06:00      2012-10-09 02:10:21 -05:00

The issue is that you're not saving the mysqli connection. Change your connect to:

$aVar = mysqli_connect('localhost','tdoylex1_dork','dorkk','tdoylex1_dork');

And then include it in your query:

$query1 = mysqli_query($aVar, "SELECT name1 FROM users
    ORDER BY RAND()
    LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];

Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.

Use a Linux Live cd/usb and boot an that to be able to directly connect to your wifi hardware or use linux as the main OS with direct access to the wifi card and then use windows as a guest os, I know that this maybe not the ideal way but it will work.

I also had this problem in my system, but after looking inside the project I saw the XML structure of the .classpath file in the project path was incorrect. After amending that file the problem was solved.

To set the status bar color, create a style.xml file under res/values-v21 folder with this content:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="AppBaseTheme" parent="AppTheme">
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@color/blue</item>
    </style>

</resources>

I have used Netbeans for java, and it works great. Not sure how it works with C++, though.

You need to alias the aggregate using the as keyword in order to call it from mysqli_fetch_assoc

$result=mysqli_query($conn,"SELECT count(*) as total from Students");
$data=mysqli_fetch_assoc($result);
echo $data['total'];

<xsl:variable name="upper">UPPER CASE</xsl:variable>
<xsl:variable name="lower" select="translate($upper,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')"/>
<xsl:value-of select ="$lower"/>

//displays UPPER CASE as upper case

I encountered a similar problem using windows command line for R script, Rscript.exe, which is very sensitive to spaces in the path. The solution was to create a virtual path to the binary folder using the windows subst command.

The following fails: "C:\Program Files\R\R-3.4.0\bin\Rscript.exe"

Doing following succeeds:

subst Z: "C:\Program Files\R\R-3.4.0"
Z:\bin\Rscript.exe

The reason the above-proposed solutions didn't work, evidently, has to do with the Rscript.exe executable's own internal path resolution from its working directory (which has a space in it) rather the windows command line being confused with the space. So using ~ or " to resolve the issue at the command line is moot. The executable must be called within a path lacking spaces.

As kmcamara discovered, this is exactly the kind of problem that VLOOKUP is intended to solve, and using vlookup is arguably the simplest of the alternative ways to get the job done.

In addition to the three parameters for lookup_value, table_range to be searched, and the column_index for return values, VLOOKUP takes an optional fourth argument that the Excel documentation calls the "range_lookup".

Expanding on deathApril's explanation, if this argument is set to TRUE (or 1) or omitted, the table range must be sorted in ascending order of the values in the first column of the range for the function to return what would typically be understood to be the "correct" value. Under this default behavior, the function will return a value based upon an exact match, if one is found, or an approximate match if an exact match is not found.

If the match is approximate, the value that is returned by the function will be based on the next largest value that is less than the lookup_value. For example, if "12AT8003" were missing from the table in Sheet 1, the lookup formulas for that value in Sheet 2 would return '2', since "12AT8002" is the largest value in the lookup column of the table range that is less than "12AT8003". (VLOOKUP's default behavior makes perfect sense if, for example, the goal is to look up rates in a tax table.)

However, if the fourth argument is set to FALSE (or 0), VLOOKUP returns a looked-up value only if there is an exact match, and an error value of #N/A if there is not. It is now the usual practice to wrap an exact VLOOKUP in an IFERROR function in order to catch the no-match gracefully. Prior to the introduction of IFERROR, no matches were checked with an IF function using the VLOOKUP formula once to check whether there was a match, and once to return the actual match value.

Though initially harder to master, deusxmach1na's proposed solution is a variation on a powerful set of alternatives to VLOOKUP that can be used to return values for a column or list to the left of the lookup column, expanded to handle cases where an exact match on more than one criterion is needed, or modified to incorporate OR as well as AND match conditions among multiple criteria.

Repeating kcamara's chosen solution, the VLOOKUP formula for this problem would be:

   =VLOOKUP(A1,Sheet1!A$1:B$600,2,FALSE)

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

A note regarding the two solutions that suggest:

1) Insert, if exception then update,

or

2) Update, if sql%rowcount = 0 then insert

The question of whether to insert or update first is also application dependent. Are you expecting more inserts or more updates? The one that is most likely to succeed should go first.

If you pick the wrong one you will get a bunch of unnecessary index reads. Not a huge deal but still something to consider.

I have a simple Location class that I use to handle all of my marker-related things. I'll paste my code below for you to take a gander at.

The last line(s) is what actually creates the marker objects. It loops through some JSON of my locations, which look something like this:

{"locationID":"98","name":"Bergqvist Järn","note":null,"type":"retail","address":"Smidesvägen 3","zipcode":"69633","city":"Askersund","country":"Sverige","phone":"0583-120 35","fax":null,"email":null,"url":"www.bergqvist-jb.com","lat":"58.891079","lng":"14.917371","contact":null,"rating":"0","distance":"45.666885421019"}

Here is the code:

If you look at the target() method in my Location class, you'll see that I keep references to the infowindow's and can simply open() and close() them because of a reference.

See a live demo: http://ww1.arbesko.com/en/locator/ (type in a Swedish city, like stockholm, and hit enter)

Set filterContext.Result

With the route name:

filterContext.Result = new RedirectToRouteResult("SystemLogin", routeValues);

You can also do something like:

filterContext.Result = new ViewResult
{
    ViewName = SharedViews.SessionLost,
    ViewData = filterContext.Controller.ViewData
};

If you want to use RedirectToAction:

You could make a public RedirectToAction method on your controller (preferably on its base controller) that simply calls the protected RedirectToAction from System.Web.Mvc.Controller. Adding this method allows for a public call to your RedirectToAction from the filter.

public new RedirectToRouteResult RedirectToAction(string action, string controller)
{
    return base.RedirectToAction(action, controller);
}

Then your filter would look something like:

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
    var controller = (SomeControllerBase) filterContext.Controller;
    filterContext.Result = controller.RedirectToAction("index", "home");
}

You may want to take a look at this very helpful article which covers this very nicely!

Just thought it might help people searching for a good solution to this problem.

http://weblogs.asp.net/rashid/archive/2009/04/15/adaptive-rendering-in-asp-net-mvc.aspx

The solution is the binding of variables through closure.

As a more basic example, here is an example function that receives and calls a callback function, as well as an example callback function:

function callbackReceiver(callback) {
    callback("Hello World");
}

function callback(value1, value2) {
    console.log(value1, value2);
}

This calls the callback and supplies a single argument. Now you want to supply an additional argument, so you wrap the callback in closure.

callbackReceiver(callback);     // "Hello World", undefined
callbackReceiver(function(value) {
    callback(value, "Foo Bar"); // "Hello World", "Foo Bar"
});

Or, more simply using ES6 Arrow Functions:

callbackReceiver(value => callback(value, "Foo Bar")); // "Hello World", "Foo Bar"

As for your specific example, I haven't used the .post function in jQuery, but a quick scan of the documentation suggests the call back should be a function pointer with the following signature:

function callBack(data, textStatus, jqXHR) {};

Therefore I think the solution is as follows:

var doSomething = function(extraStuff) {
    return function(data, textStatus, jqXHR) {
        // do something with extraStuff
    };
};

var clicked = function() {
    var extraStuff = {
        myParam1: 'foo',
        myParam2: 'bar'
    }; // an object / whatever extra params you wish to pass.

    $.post("someurl.php", someData, doSomething(extraStuff), "json");
};

What is happening?

In the last line, doSomething(extraStuff) is invoked and the result of that invocation is a function pointer.

Because extraStuff is passed as an argument to doSomething it is within scope of the doSomething function.

When extraStuff is referenced in the returned anonymous inner function of doSomething it is bound by closure to the outer function's extraStuff argument. This is true even after doSomething has returned.

I haven't tested the above, but I've written very similar code in the last 24 hours and it works as I've described.

You can of course pass multiple variables instead of a single 'extraStuff' object depending on your personal preference/coding standards.

For Angular 2 Final, we now have a new API that cleanly resets the form:

@Component({...})
class App {

    form: FormGroup;
     ...
    reset() {
       this.form.reset();
   }
}

This API not only resets the form values, but also sets the form field states back to ng-pristine and ng-untouched.

The only difference is that you're creating an unnecessary promise when you do return Promise.resolve("bbb"). Returning a promise from an onFulfilled() handler kicks off promise resolution. That's how promise chaining works.

Firstly, see the different between absolute path and relative path here:

An absolute path always contains the root element and the complete directory list required to locate the file.

Alternatively, a relative path needs to be combined with another path in order to access a file.

In constructor File(String pathname), Javadoc's File class said that

A pathname, whether abstract or in string form, may be either absolute or relative.

If you want to get relative path, you must be define the path from the current working directory to file or directory.Try to use system properties to get this.As the pictures that you drew:

String localDir = System.getProperty("user.dir");
File file = new File(localDir + "\\config.properties");

Moreover, you should try to avoid using similar ".", "../", "/", and other similar relative to the file location relative path, because when files are moved, it is harder to handle.

Try this:

    ServersTable.Columns.Clear();
    ServersTable.DataSource = SBind;

If you don't want to clear all the existing columns, you have to set DataPropertyName for each existing column like this:

for (int i = 0; i < ServersTable.ColumnCount; ++i) {
  DTable.Columns.Add(new DataColumn(ServersTable.Columns[i].Name));
  ServersTable.Columns[i].DataPropertyName = ServersTable.Columns[i].Name;
}

I don't have enough reputation to post a comment reply, but took TJ Crowder's excellent answer and fully defined the code on a 100ms timer. (He left some details to the imagination.)

Thanks OP for the question, and TJ for the answer! You're both a great help. Code is embedded below as a mirror of isbin.

By.cssSelector(".ban") or By.cssSelector(".hot") or By.cssSelector(".ban.hot") should all select it unless there is another element that has those classes.

In CSS, .name means find an element that has a class with name. .foo.bar.baz means to find an element that has all of those classes (in the same element).

However, each of those selectors will select only the first element that matches it on the page. If you need something more specific, please post the HTML of the other elements that have those classes.

Just removing uses-sdk tag works for me for such problems.

I'm using EF6, and I find something strange,

Suppose Customer has constructor with parameter ,

if I use new Customer(id, "name"), and do

 using (var db = new EfContext("name=EfSample"))
 {
    db.Customers.Add( new Customer(id, "name") );
    db.SaveChanges();
 }

It run through without error, but when I look into the DataBase, I find in fact that the data Is NOT be Inserted,

But if I add the curly brackets, use new Customer(id, "name"){} and do

 using (var db = new EfContext("name=EfSample"))
 {
    db.Customers.Add( new Customer(id, "name"){} );
    db.SaveChanges();
 }

the data will then actually BE Inserted,

seems the Curly Brackets make the difference, I guess that only when add Curly Brackets, entity framework will recognize this is a real concrete data.

this can be achieved with the css calc() operator

@media screen and (min-width: 480px) {
    body {
        background-color: lightgreen;
        zoom:calc(100% / 480);
    }
}

ASP.NET controls should rather be placed in aspx markup file. That is the preferred way of working with them. So add FileUpload control to your page. Make sure it has all required attributes including ID and runat:

<asp:FileUpload ID="FileUpload1" runat="server" />

Instance of FileUpload1 will be automatically created in auto-generated/updated *.designer.cs file which is a partial class for your page. You usually do not have to care about what's in it, just assume that any control on an aspx page is automatically instantiated.

Add a button that will do the post back:

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

Then go to your *.aspx.cs file where you have your code and add button click handler. In C# it looks like this:

protected void Button1_Click(object sender, EventArgs e)
{
  if (this.FileUpload1.HasFile)
  {
    this.FileUpload1.SaveAs("c:\\" + this.FileUpload1.FileName);
  }
}

And that's it. All should work as expected.

You can use your favourite telnet (not recommended) or ssh (recommended) application to connect to your Synology box and use it as a terminal.

1. Enable the command line interface (CLI) from the Network Services
2. Define the protocol and the user and make sure the user has password set
3. Access the CLI

To me the best way is -

1. Create an new issue with that repository on github and then upload the file in gif format.To convert video files into gif format you can use this website http://www.online-convert.com/
2. Submit the newly created issue.
3. Copy the address of the uploaded file

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

We can use the PHP cURL library to generate simple HTTP POST request. The following example shows you how to create a simple SOAP request using cURL.

Create the soap-server.php which write the SOAP request into soap-request.xml in web folder.

We can use the PHP cURL library to generate simple HTTP POST request. The following example shows you how to create a simple SOAP request using cURL.

Create the soap-server.php which write the SOAP request into soap-request.xml in web folder.


<?php
  $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
  $f = fopen("./soap-request.xml", "w");
  fwrite($f, $HTTP_RAW_POST_DATA);
  fclose($f);
?>


The next step is creating the soap-client.php which generate the SOAP request using the cURL library and send it to the soap-server.php URL.

<?php
  $soap_request  = "<?xml version=\"1.0\"?>\n";
  $soap_request .= "<soap:Envelope xmlns:soap=\"http://www.w3.org/2001/12/soap-envelope\" soap:encodingStyle=\"http://www.w3.org/2001/12/soap-encoding\">\n";
  $soap_request .= "  <soap:Body xmlns:m=\"http://www.example.org/stock\">\n";
  $soap_request .= "    <m:GetStockPrice>\n";
  $soap_request .= "      <m:StockName>IBM</m:StockName>\n";
  $soap_request .= "    </m:GetStockPrice>\n";
  $soap_request .= "  </soap:Body>\n";
  $soap_request .= "</soap:Envelope>";

  $header = array(
    "Content-type: text/xml;charset=\"utf-8\"",
    "Accept: text/xml",
    "Cache-Control: no-cache",
    "Pragma: no-cache",
    "SOAPAction: \"run\"",
    "Content-length: ".strlen($soap_request),
  );

  $soap_do = curl_init();
  curl_setopt($soap_do, CURLOPT_URL, "http://localhost/php-soap-curl/soap-server.php" );
  curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10);
  curl_setopt($soap_do, CURLOPT_TIMEOUT,        10);
  curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
  curl_setopt($soap_do, CURLOPT_POST,           true );
  curl_setopt($soap_do, CURLOPT_POSTFIELDS,     $soap_request);
  curl_setopt($soap_do, CURLOPT_HTTPHEADER,     $header);

  if(curl_exec($soap_do) === false) {
    $err = 'Curl error: ' . curl_error($soap_do);
    curl_close($soap_do);
    print $err;
  } else {
    curl_close($soap_do);
    print 'Operation completed without any errors';
  }
?>


Enter the soap-client.php URL in browser to send the SOAP message. If success, Operation completed without any errors will be shown and the soap-request.xml will be created.

<?xml version="1.0"?>

      <m:StockName>IBM</m:StockName>
    </m:GetStockPrice>
  </soap:Body>
</soap:Envelope>

You could also use XPCOM, say in XUL based apps like Firefox, Thunderbird or Komodo.

I've found that the command line is my friend in these situations.

I installed the SQL Server 2012 Enterprise Management Tools, including Management Studio, off the DVD (mounted ISO actually), without installing anything else using this command:

e:\setup.exe /Q /IACCEPTSQLSERVERLICENSETERMS /ACTION=install /FEATURES=Tools

Run the command prompt with elevated privileges. And be patient, as it has to unpack the installation files. Don't try to install the MSI files directly, as you lose the dependency checking packaged with the main installer.

Again, this is to install the full version off the Enterprise or Developer media, if you have it, and do not wish to settle for the free Express edition.

In Xcode > 4.3:

You click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column.

Good Luck !!!

I wasn't satisfied with what was offered, so here's my proposal, using jQuery :

            <div id="playlist">
                <audio id="player" controls preload="metadata" volume="1">
                  <source src="" type="audio/mpeg">
                  Sorry, this browser doesn't support HTML 5.0
                </audio>
                <ul></ul>
            </div>

            <script>
                var folder = "audio";
                var playlist = [
                    "example1.mp3",
                    "example2.mp3"
                ];
                for (var i in playlist) {
                    jQuery('#playlist ul').append('<li>'+playlist[i]+'</li>');
                }

                var player = document.getElementById('player');
                var playing = playlist[0];
                player.src = folder + '/' + playing;

                function display(id) {
                    var list = jQuery('#playlist ul').children();
                    list.removeClass('playing');
                    jQuery(list[id]).addClass('playing');
                }

                display(0);

                player.onended = function(){
                    var ind_next = playlist.indexOf(playing) + 1;

                    if (ind_next !== 0) {
                        player.src = folder + '/' + playlist[ind_next];
                        playing = player.src;
                        display(ind_next)
                        player.play();
                    }
                }
            </script>

You only have to edit the playlist array, and you're done

Another case is http redirection. If your page redirects http requests to https, then may be your partial view tries to redirect by itself.

It causes same problem again. For this problem, you can reorganize your .net error pages or iis error pages configuration.

Just make sure you are redirecting requests to right error or not found page and make sure this error page contains non problematic partial. If your page supports only https, do not forward requests to error page without using https, if error page contains partial, this partials tries to redirect seperately from requested url, it causes problem.

Here is how I made a script that could take either command line inputs or have a text file redirected.

if ($#ARGV < 1) {
    @ARGV = ();
    @ARGV = <>;
    chomp(@ARGV);
}

This will reassign the contents of the file to @ARGV, from there you just process @ARGV as if someone was including command line options.

WARNING

If no file is redirected, the program will sit their idle because it is waiting for input from STDIN.

I have not figured out a way to detect if a file is being redirected in yet to eliminate the STDIN issue.

Reload the datasource of your grid after the update

myGrid.ItemsSource = null;
myGrid.ItemsSource = myDataSource;

Another excellent plugin: http://documentcloud.github.com/visualsearch/

If I understand what you need, try this:

SELECT id, pass, AVG(val) AS val_1 
FROM data_r1 
GROUP BY id, pass;

Or, if you want just one row for every id, this:

SELECT d1.id,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 1) as val_1,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 2) as val_2,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 3) as val_3,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 4) as val_4,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 5) as val_5,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 6) as val_6,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 7) as val_7
from data_r1 d1
GROUP BY d1.id

Make sure that you work with the correct separator. I replaced all / in a relative path with a File.separator. This worked fine in the IDE, however did not work in the build JAR.

It looks like your client is trying to connect to a non-existent server. In a shell window, run:

$ nc -l 5000

before running your Python code. It will act as a server listening on port 5000 for you to connect to. Then you can play with typing into your Python window and seeing it appear in the other terminal and vice versa.

In a scenario where tables are in 3rd normal form, joins between tables shouldn't change. I.e. join CUSTOMERS and PAYMENTS should always remain the same.

However, we should distinguish joins from filters. Joins are about relationships and filters are about partitioning a whole.

Some authors, referring to the standard (i.e. Jim Melton; Alan R. Simon (1993). Understanding The New SQL: A Complete Guide. Morgan Kaufmann. pp. 11–12. ISBN 978-1-55860-245-8.), wrote about benefits to adopt JOIN syntax over comma-separated tables in FROM clause.

I totally agree with this point of view.

There are several ways to write SQL and achieve the same results but for many of those who do teamwork, source code legibility is an important aspect, and certainly separate how tables relate to each other from specific filters was a big leap in sense of clarifying source code.

I had the same issue while following the Laravel docs (https://laravel.com/docs/5.2/homestead)

My problem was very simple, I missed read this part in the docs:

Homestead.yaml file will be placed in the ~/.homestead hidden directory:

So I was updating the wrong Homestead.yaml file, since the file was moved when I ran the bash init.sh command.

I only realised this after a lot of searching, so hope this will help someone.

In case this helps anyone, I was getting this error when attempting to run aspnet_regiis.exe:

Operation failed with 0x8007000B

An attempt was made to load a program with an incorrect format

As it turns out, the server was running 2008 64 bit and I was trying to run the 32 bit version of the utility. Running the version found in \Windows\Microsoft.NET\Framework64\v2.0.50727 fixed the issue.

c:\Windows\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis.exe -i

@Loki Astari's answer is excellent.

However there are times with multiple static objects where you need to be able to guarantee that the singleton will not be destroyed until all your static objects that use the singleton no longer need it.

In this case std::shared_ptr can be used to keep the singleton alive for all users even when the static destructors are being called at the end of the program:

class Singleton
{
public:
    Singleton(Singleton const&) = delete;
    Singleton& operator=(Singleton const&) = delete;

    static std::shared_ptr<Singleton> instance()
    {
        static std::shared_ptr<Singleton> s{new Singleton};
        return s;
    }

private:
    Singleton() {}
};

An easy short hand way would be to use +x It keeps the sign intact as well as the decimal numbers. The other alternative is to use parseFloat(x). Difference between parseFloat(x) and +x is for a blank string +x returns 0 where as parseFloat(x) returns NaN.

Looks like you are hitting the limit on connections per server. I see you are loading a lot of static files and my advice is to separate them on subdomains and serve them directly with Nginx for example.

• Create a subdomain called img.yoursite.com and load all your images from there.

• Create a subdomain called scripts.yourdomain.com and load all your JS and CSS files from there.

• Create a subdomain called sounds.yoursite.com and load all your MP3s from there... etc..

Nginx has great options for directly serving static files and managing the static files caching.

Use PtrSafe and see how that works on Excel 2010.

Corrected typo from the book "Microsoft Excel 2010 Power Programming with VBA".

#If vba7 and win64 then
  declare ptrsafe function ....
#Else
  declare function ....
#End If

val(application.version)>12.0 won't work because Office 2010 has both 32 and 64 bit versions

I had the same issue for a while and had a very hard time figuring it out. My problem was that I had the site working for a while with the sessions working right, and then all of the sudden everything broke.

Apparently, your session_save_path(), for me it was /var/lib/php5/, needs to have correct permissions (the user running php, eg www-data needs write access to the directory). I accidentally changed it, breaking sessions completely.

Run sudo chmod -R 700 /var/lib/php5/ and then sudo chown -R www-data /var/lib/php5/ so that the php user has access to the folder.

Provided your class extends a class with a generic parameter, you can also get this at runtime via reflection, and then use that for comparison, i.e.

class YourClass extends SomeOtherClass<String>
{

   private Class<?> clazz;

   public Class<?> getParameterizedClass()
   {
      if(clazz == null)
      {
         ParameterizedType pt = (ParameterizedType)this.getClass().getGenericSuperclass();
          clazz = (Class<?>)pt.getActualTypeArguments()[0];
       }
       return clazz;
    }
}

In the case above, at runtime you will get String.class from getParameterizedClass(), and it caches so you don't get any reflection overhead upon multiple checks. Note that you can get the other parameterized types by index from the ParameterizedType.getActualTypeArguments() method.

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

You don't set value to default in a table. You should clear the option "Default value or Binding" first.

You can add the TextField as a child to a Container that has a BoxDecoration with border property:

new Container(
  margin: const EdgeInsets.all(15.0),
  padding: const EdgeInsets.all(3.0),
  decoration: BoxDecoration(
    border: Border.all(color: Colors.blueAccent)
  ),
  child: Text("My Awesome Border"),
)

The database size does matter. If you have more than one table with more than a million records, then performance starts indeed to degrade. The number of records does of course affect the performance: MySQL can be slow with large tables. If you hit one million records you will get performance problems if the indices are not set right (for example no indices for fields in "WHERE statements" or "ON conditions" in joins). If you hit 10 million records, you will start to get performance problems even if you have all your indices right. Hardware upgrades - adding more memory and more processor power, especially memory - often help to reduce the most severe problems by increasing the performance again, at least to a certain degree. For example 37 signals went from 32 GB RAM to 128GB of RAM for the Basecamp database server.

Difficult task. I would normally suggest to grab a debugger/memory profiler like Valgrind and run the programs one after one in it. Soon or later you will find the program that leaks and can tell it the devloper or fix it yourself.

WebbieDave's solution will work. If you don't want to overwrite anything that might already be at 'name', you can also do something like this:

$options['inputs']['name'][] = $new_input['name'];

You can create a new file, setenv.sh (or setenv.bat) inside tomcats bin directory and add following line there

export CLASSPATH=$CLASSPATH:/XX/xx/PATH_TO_DIR

Basically the answer from Jani Hartikainen is right! I upvoted his answer. What was missing on my system (based on Ubuntu 15.04) was to enable PDO Extension in my php.ini

extension=pdo.so
extension=pdo_mysql.so

restart the webserver (e.g. with "sudo service apache2 restart") -> every fine :-)

To find where your current active php.ini file is located you can use phpinfo() or some other hints from here: https://www.ostraining.com/blog/coding/phpini-file/

FYI, to access any script via command-line like you were trying, you need to have the script registered as a shell-script (or any kind of script like .js, .rb) in the system like these files in the the dir /usr/bin in UNIX. And, system must know where to find them. i.e. the location must be loaded in $PATH array.

In your case, the script webpack-dev-server is already installed somewhere inside ./node_modules directory, but system does not know how to access it. So, to access the command webpack-dev-server, you need to install the script in global scope as well.

$ npm install webpack-dev-server -g

Here, -g refers to global scope.

However, this is not recommended way because you might face version conflicting issues; so, instead you can set a command in npm's package.json file like:

  "scripts": {
    "start": "webpack-dev-server -d --config webpack.dev.config.js --content-base public/ --progress --colors"
   }

This setting will let you access the script you want with simple command

$ npm start

So short to memorize and play. And, npm knows the location of the module webpack-dev-server.

The same happened for me with eslint module. EsLinter throw Parsing error: Invalid left-hand side in assignment expression for await in second if statement.

if (condition_one) {
  let result = await myFunction()
}

if (condition_two) {
  let result = await myFunction() // eslint parsing error
}

As strange as it sounds what fixed this error was to add ; semicolon at the end of line where await occurred.

if (condition_one) {
  let result = await myFunction();
}

if (condition_two) {
  let result = await myFunction();
}

Absolutely possible. Many ways to do it. The fastest way, create condition with try - catch method.. try your certain font style condition, catch the error, and define the other font style.

Here's a simplified version, for MacVim, using the the Wikia article examples (cf. link from gun's comment).

" Move selection up/down (add =gv to reindent after move)
:vmap <D-S-Up> :m-2<CR>gv
:vmap <D-S-Down> :m'>+<CR>gv

I'm using only the block selection variant, because all it takes is Shift-V to select the current line, and optionally cursor up/down to select some more lines.

According to the shortcuts above, pressing Cmd-Shift-Up/Down will shift the block selection up/down. "D" is the Command key in MacVim, for Windows try "C" (Control), or "A" (Alt) (eg. <C-A-f> would be Control Alt f).

The Wikia article adds "=gv" to these, which has the effect to adjust the indentation of the block after the move, based on surrounding text. This is confusing so I removed it, and added shortcuts for quickly indenting the selection instead.

" Indent selection left/right (Cmd Shift Left/Right is used for Tab switching)
:vmap <D-A-Left> <gv
:vmap <D-A-Right> >gv

Mind, the same can be done with << and >> but the selection would be lost, so these shortcuts above allow to indent multiple times and still move the block around because the selection is maintained.

My MacVim is configured to switch Tabs with Cmd-Shift-Left/Right so I used Cmd-Alt-Left/Right.

Here's the Tab switching for MacVim (put in .gvimrc with the rest above):

:macm Window.Select\ Previous\ Tab key=<D-S-Left>
:macm Window.Select\ Next\ Tab key=<D-S-Right>

Which version of JUnit is this? I've only ever seen delta, not epsilon - but that's a side issue!

From the JUnit javadoc:

delta - the maximum delta between expected and actual for which both numbers are still considered equal.

It's probably overkill, but I typically use a really small number, e.g.

private static final double DELTA = 1e-15;

@Test
public void testDelta(){
    assertEquals(123.456, 123.456, DELTA);
}

If you're using hamcrest assertions, you can just use the standard equalTo() with two doubles (it doesn't use a delta). However if you want a delta, you can just use closeTo() (see javadoc), e.g.

private static final double DELTA = 1e-15;

@Test
public void testDelta(){
    assertThat(123.456, equalTo(123.456));
    assertThat(123.456, closeTo(123.456, DELTA));
}

FYI the upcoming JUnit 5 will also make delta optional when calling assertEquals() with two doubles. The implementation (if you're interested) is:

private static boolean doublesAreEqual(double value1, double value2) {
    return Double.doubleToLongBits(value1) == Double.doubleToLongBits(value2);
}

Just to throw in another example. Imagine you have the following list:

nums = [4,2,2,1,3]

and you want to turn it into a dict where the key is the index and value is the element in the list. You can do so with the following line of code:

{index:nums[index] for index in range(0,len(nums))}

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

-n is "not to overwrite" but his question is totally opposite what you replied for.

To avoid this confirmation you can simply run the cp command wiht absolute path, it will avoid the alias.

/bin/cp sourcefile destination

In your case there are 3 extra y axis (4 in total) and the best code that could be used to achieve what you want and deal with other cases is illustrated above:

clear
clc

x = linspace(0,1,10);
N = numel(x);
y = rand(1,N);
y_extra_1 = 5.*rand(1,N)+5;
y_extra_2 = 50.*rand(1,N)+20;
Y = [y;y_extra_1;y_extra_2];

xLimit = [min(x) max(x)];
xWidth = xLimit(2)-xLimit(1);
numberOfExtraPlots = 2;
a = 0.05;
N_ = numberOfExtraPlots+1;

for i=1:N_
    L=1-(numberOfExtraPlots*a)-0.2;
    axesPosition = [(0.1+(numberOfExtraPlots*a)) 0.1 L 0.8];
    if(i==1)
        color = [rand(1),rand(1),rand(1)];
        figure('Units','pixels','Position',[200 200 1200 600])
        axes('Units','normalized','Position',axesPosition,...
            'Color','w','XColor','k','YColor',color,...
            'XLim',xLimit,'YLim',[min(Y(i,:)) max(Y(i,:))],...
            'NextPlot','add');
        plot(x,Y(i,:),'Color',color);
        xlabel('Time (s)');

        ylab = strcat('Values of dataset 0',num2str(i));
        ylabel(ylab)

        numberOfExtraPlots = numberOfExtraPlots - 1;
    else
        color = [rand(1),rand(1),rand(1)];
        axes('Units','normalized','Position',axesPosition,...
            'Color','none','XColor','k','YColor',color,...
            'XLim',xLimit,'YLim',[min(Y(i,:)) max(Y(i,:))],...
            'XTick',[],'XTickLabel',[],'NextPlot','add');
        V = (xWidth*a*(i-1))/L;
        b=xLimit+[V 0];
        x_=linspace(b(1),b(2),10);
        plot(x_,Y(i,:),'Color',color);
        ylab = strcat('Values of dataset 0',num2str(i));
        ylabel(ylab)

        numberOfExtraPlots = numberOfExtraPlots - 1;
    end
end

The code above will produce something like this:

The Placeholder does not render any tags for itself, so it is great for grouping content without the overhead of outer HTML tags.

The Panel does have outer HTML tags but does have some cool extra properties.

• BackImageUrl: Gets/Sets the background image's URL for the panel

• HorizontalAlign: Gets/Sets the
  horizontal alignment of the parent's contents

• Wrap: Gets/Sets whether the
  panel's content wraps

For my case was encountering this issue with Laravel 6.x and managed to sort it out by installing an SSL Certificate. Tried playing around with .htaccess but never worked. I'm using the default Laravel 6.x .htaccess file which has the following contents

Sorry, but--in my opinion--RichieHindle is completely right about saying that method...

It's a function which is a member of a class.

Here is the example of a function that becomes the member of the class. Since then it behaves as a method of the class. Let's start with the empty class and the normal function with one argument:

>>> class C:
...     pass
...
>>> def func(self):
...     print 'func called'
...
>>> func('whatever')
func called

Now we add a member to the C class, which is the reference to the function. After that we can create the instance of the class and call its method as if it was defined inside the class:

>>> C.func = func
>>> o = C()
>>> o.func()
func called

We can use also the alternative way of calling the method:

>>> C.func(o)
func called

The o.func even manifests the same way as the class method:

>>> o.func
<bound method C.func of <__main__.C instance at 0x000000000229ACC8>>

And we can try the reversed approach. Let's define a class and steal its method as a function:

>>> class A:
...     def func(self):
...         print 'aaa'
...
>>> a = A()
>>> a.func
<bound method A.func of <__main__.A instance at 0x000000000229AD08>>
>>> a.func()
aaa

So far, it looks the same. Now the function stealing:

>>> afunc = A.func
>>> afunc(a)
aaa    

The truth is that the method does not accept 'whatever' argument:

>>> afunc('whatever')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unbound method func() must be called with A instance as first 
  argument (got str instance instead)

IMHO, this is not the argument against method is a function that is a member of a class.

Later found the Alex Martelli's answer that basically says the same. Sorry if you consider it duplication :)

The time_t Wikipedia article article sheds some light on this. The bottom line is that the type of time_t is not guaranteed in the C specification.

The time_t datatype is a data type in the ISO C library defined for storing system time values. Such values are returned from the standard time() library function. This type is a typedef defined in the standard header. ISO C defines time_t as an arithmetic type, but does not specify any particular type, range, resolution, or encoding for it. Also unspecified are the meanings of arithmetic operations applied to time values.

Unix and POSIX-compliant systems implement the time_t type as a signed integer (typically 32 or 64 bits wide) which represents the number of seconds since the start of the Unix epoch: midnight UTC of January 1, 1970 (not counting leap seconds). Some systems correctly handle negative time values, while others do not. Systems using a 32-bit time_t type are susceptible to the Year 2038 problem.

It might seem like a hack, but I personally prefer copying the cells as text (or exporting as a CSV) into Winmerge or any other diff tool. Assuming the two sheets contain mostly identical data, Winmerge will show the differences immediately.

I'd recommend the DIY way which, combined with a good hashCode() and equals() method should be easy to proof in a unit test.

Just replace "UTC" with "GMT" -- simple and doesn't break correctly formatted dates:

DateTime.Parse("Tue, 1 Jan 2008 00:00:00 UTC".Replace("UTC", "GMT"))

Just point to any View inside the Activity's XML. You can give an id to the root viewGroup, for example, and use:

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);    
   setContentView(R.layout.main_activity);
   View parentLayout = findViewById(android.R.id.content);
   Snackbar.make(parentLayout, "This is main activity", Snackbar.LENGTH_LONG) 
        .setAction("CLOSE", new View.OnClickListener() {
            @Override 
            public void onClick(View view) {

            } 
        }) 
        .setActionTextColor(getResources().getColor(android.R.color.holo_red_light ))
        .show(); 
   //Other stuff in OnCreate();
}

The built in FTP command doesn't have a facility for security. Use cUrl instead. It's scriptable, far more robust and has FTP security.

Android Studio 3.5.3 It works with this configuration.

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

little few change in your code :

TextView tv = (TextView)findViewById(R.id.charCounts);
textMessage = (EditText)findViewById(R.id.textMessage);
textMessage.addTextChangedListener(new TextWatcher(){
    public void afterTextChanged(Editable s) {
        tv.setText(String.valueOf(s.toString().length()));
    }
    public void beforeTextChanged(CharSequence s, int start, int count, int after){}
    public void onTextChanged(CharSequence s, int start, int before, int count){}
}); 

think you're making a mistake. Take a look at this: http://golang.org/pkg/container/heap/ Building a heap isn'y O(n). However, inserting is O(lg(n). I'm assuming initialization is O(n) if you set a heap size b/c the heap needs to allocate space and set up the data structure. If you have n items to put into the heap then yes, each insert is lg(n) and there are n items, so you get n*lg(n) as u stated

When you call sqlite3_open() you specify the filepath the database is opened from/saved to, if it is not an absolute path it is specified relative to your current working directory.

The above is fine (as I said in comment) unless your WSDL is accessible with https:// too.

Here is my workaround for this:

Set you SSLSocketFactory as default:

HttpsURLConnection.setDefaultSSLSocketFactory(...);

For Apache CXF which I use you need also add these lines to your config:

<http-conf:conduit name="*.http-conduit">
  <http-conf:tlsClientParameters useHttpsURLConnectionDefaultSslSocketFactory="true" />
<http-conf:conduit>

Your requirements are all over the place, but this is the solution to my understanding of them:

To group by Reference property:

var refGroupQuery = (from m in context.Measurements
            group m by m.Reference into refGroup
            select refGroup);

Now you say you want to limit results by "most recent numOfEntries" - I take this to mean you want to limit the returned Measurements... in that case:

var limitedQuery = from g in refGroupQuery
                   select new
                   {
                       Reference = g.Key,
                       RecentMeasurements = g.OrderByDescending( p => p.CreationTime ).Take( numOfEntries )
                   }

To order groups by first Measurement creation time (note you should order the measurements; if you want the earliest CreationTime value, substitue "g.SomeProperty" with "g.CreationTime"):

var refGroupsOrderedByFirstCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.OrderBy( g => g.SomeProperty ).First().CreationTime );

To order groups by average CreationTime, use the Ticks property of the DateTime struct:

var refGroupsOrderedByAvgCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.Average( g => g.CreationTime.Ticks ) );

I am not that much good at programming, but was really interested in this topic so I tried to understand how to solve that without using any libraries or scripts

I wrote this on scratchpad

var toAlgebraic = function(f1, f2) {
    let f1_base = Math.pow(10, f1.split('.')[1].length);
    let f2_base = Math.pow(10, f2.split('.')[1].length);
    f1 = parseInt(f1.replace('.', ''));
    f2 = parseInt(f2.replace('.', ''));

    let dif, base;
    if (f1_base > f2_base) {
        dif = f1_base / f2_base;
        base = f1_base;
        f2 = f2 * dif;
    } else {
        dif = f2_base / f1_base;
        base = f2_base;
        f1 = f1 * dif;
    }

    return (f1 * f2) / base;
};

console.log(0.1 * 0.2);
console.log(toAlgebraic("0.1", "0.2"));

you might need refactor this code, because I am not good at programming :)

Since the question was asked/answered long time ago, those top answers do not work for me. Here's my solution, in 2020.

Background: Fresh mysql/mariadb installed by homebrew.

Problem: The password for root is not empty and unknown.

The fix:

1. mysql -u YOUR-SYSTEM-USERNAME -p
2. The password is empty (press enter)
3. ALTER USER 'root'@'localhost' IDENTIFIED BY 'NEW-ROOT-PASSWORD';
4. FLUSH PRIVILEGES;

The reason:

1. Homebrew will create a user with root privileges named by the current MacOS username.
2. it has no password
3. Since it has all privileges, just reset the root password with that user.
4. The initial password for root was randomly generated.

Try to add title and alt properties to your image.... Gmail and some others blocks images without some attributes.. and it is also a logic to include your email to be read as spam.

Ctrl + L will usually clear the screen. Works from the Bash prompt (obviously) and in GDB, and a lot of other prompts.

Quote the Windows help for the set command (set /?):

If Command Extensions are enabled, then there are several dynamic
environment variables that can be expanded but which don't show up in
the list of variables displayed by SET.  These variable values are
computed dynamically each time the value of the variable is expanded.
If the user explicitly defines a variable with one of these names, then
that definition will override the dynamic one described below:

%CD% - expands to the current directory string.

%DATE% - expands to current date using same format as DATE command.

%TIME% - expands to current time using same format as TIME command.

%RANDOM% - expands to a random decimal number between 0 and 32767.

%ERRORLEVEL% - expands to the current ERRORLEVEL value

%CMDEXTVERSION% - expands to the current Command Processor Extensions
    version number.

%CMDCMDLINE% - expands to the original command line that invoked the
    Command Processor.

Note the %CD% - expands to the current directory string. part.

Swift 5

Use following steps to hide iOS Status Bar:

1. Open on Info.plist.
2. Add new key View controller-based status bar appearance and value set to NO.
3. Add new key Status bar is initially hidden and value set to YES.
4. Re-compile project.
5. Status bar should hidden on iOS phone now.

Final Settings Screenshot:

This is working on Xcode 10.2

Even if the question is old but i will share the solution that answers perfectly the question :

SET SERVEROUTPUT ON;

DECLARE
    RC SYS_REFCURSOR;
    Result1 varchar2(25);
    Result2 varchar2(25);
BEGIN
    OPEN RC FOR SELECT foo, bar into Result1, Result2 FROM foobar;
    DBMS_SQL.RETURN_RESULT(RC);
END;

If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE

Edit: On the model overview it's under Physical Schemata

Screenshot:

To float a div to the right pull-right is the recommend way, I feel you are doing things right may be you only need to use text-align:right;

  <div class="container">
     <div class="row-fluid">
      <div class="span6">
           <p>Text left</p>
      </div>
      <div class="span6 pull-right" style="text-align:right">
           <p>text right</p>
      </div>
  </div>
 </div>      
 </div>

Be careful if you have spaces in your string variables and you check for existence. Be sure to quote them properly.

if [ ! "${somepath}" ] || [ ! "${otherstring}" ] || [ ! "${barstring}" ] ; then

Yet another way to do this:

(Get-Date).AddDays(-1).Date.AddHours(22)

Try this

@RequestMapping(value = "proffessional", method = RequestMethod.POST)
    public @ResponseBody
    String forgotPassword(@ModelAttribute("PROFESSIONAL") UserProfessionalForm professionalForm,
            BindingResult result, Model model) {

        UserProfileVO userProfileVO = new UserProfileVO();
        userProfileVO.setUser(sessionData.getUser());
        userService.saveUserProfile(userProfileVO);
        model.addAttribute("professional", professionalForm);
        return "Your Professional Details Updated";
    }

You certainly can. Others have pointed out correctly that you need to do i += 3. You can't do what you have posted because all you are doing here is adding i + 3 but never assigning the result back to i. i++ is just a shorthand for i = i + 1, similarly i +=3 is a shorthand for i = i + 3.

a=int(raw_input('1st no \n'))
b=int(raw_input('2nd no \n'))

def gcd(m,n):
    z=abs(m-n)
    if (m-n)==0:
        return n
    else:
        return gcd(z,min(m,n))


print gcd(a,b)

A different approach based on euclid's algorithm.

wxHexEditor is the only GUI disk editor for linux. to google "wxhexeditor site:archive.getdeb.net" and download the .deb file to install

I got the issue too, and at last I found the solution for my issue.I was builded the controller's UI in storyboard , but the controller's UI did not relate its control to code, I use this code to init vc:

    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Me" bundle:nil];
    [sb instantiateViewControllerWithIdentifier:@"HeaderViewController"];

This code above will cause the issue, and after I changed the init code to this below, I resolved the problem:

HeaderViewController *head_vc = [[HeaderViewController alloc] init];

Using Glide library:

Glide.with(context)
  .load(new File(url)
  .diskCacheStrategy(DiskCacheStrategy.ALL)
  .into(imageView);

The .css() function doesn't queue behind running animations, it's instantaneous.

To match the behaviour that you're after, you'd need to do the following:

$(document).ready(function() {
  $("button").mouseover(function() {
    var p = $("p#44.test").css("background-color", "yellow");
    p.hide(1500).show(1500);
    p.queue(function() {
      p.css("background-color", "red");
    });
  });
});

The .queue() function waits for running animations to run out and then fires whatever's in the supplied function.

I used with context

//Convert bitmap to drawable
Drawable drawable = new BitmapDrawable(context.getResources(), bitmap);

Based on the very good answers above, here is what I came up with. This is very similar to @Rodrigo's answer, but addresses @Oliver's concern from the comment on that answer. This also provides the option of including the model string in the output string.

+ (NSString *) deviceModel {
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *model = malloc(size);
    sysctlbyname("hw.machine", model, &size, NULL, 0);
    NSString *deviceModel = [NSString stringWithCString:model encoding:NSUTF8StringEncoding];
    free(model);      

    return deviceModel;
}

+ (NSString *) deviceName {
    NSString *deviceModel = [DeviceGateway deviceModel];

    NSString *aux = [[deviceModel componentsSeparatedByString:@","] objectAtIndex:0];

    if ([aux rangeOfString:@"iPhone"].location != NSNotFound) {
        int version = [[aux stringByReplacingOccurrencesOfString:@"iPhone" withString:@""] intValue];
        if (version == 3) return @"iPhone4";
        if (version == 4) return @"iPhone4s";
        return @"Newer iPhone";
    }
    if ([aux rangeOfString:@"iPod"].location != NSNotFound) {
        int version = [[aux stringByReplacingOccurrencesOfString:@"iPod" withString:@""] intValue];
        if (version == 4) return @"iPod4thGen";
        return @"Newer iPod";
    }

    //If none was found, send the original string
    return deviceModel;
}

+ (NSString *) deviceNameWithDeviceModel:(BOOL)shouldIncludeDeviceModel {
    if (shouldIncludeDeviceModel) {
        return [NSString stringWithFormat:@"%@ (%@)", [DeviceGateway deviceName], [DeviceGateway deviceModel]];
    }

    return [DeviceGateway deviceName];
}

switch statements would be good to replace if you find yourself adding new states or new behaviour to the statements:

int state;

String getString() {
   switch (state) {
     case 0 : // behaviour for state 0
           return "zero";
     case 1 : // behaviour for state 1
           return "one";
   }
   throw new IllegalStateException();
}

double getDouble() {

   switch (this.state) {
     case 0 : // behaviour for state 0
           return 0d;
     case 1 : // behaviour for state 1
           return 1d;
   }
   throw new IllegalStateException();
}

Adding new behaviour requires copying the switch, and adding new states means adding another case to every switch statement.

In Java, you can only switch a very limited number of primitive types whose values you know at runtime. This presents a problem in and of itself: states are being represented as magic numbers or characters.

Pattern matching, and multiple if - else blocks can be used, though really have the same problems when adding new behaviours and new states.

The solution which others have suggested as "polymorphism" is an instance of the State pattern:

Replace each of the states with its own class. Each behaviour has its own method on the class:

IState state;

String getString() {
   return state.getString();
}

double getDouble() {
   return state.getDouble();
}

Each time you add a new state, you have to add a new implementation of the IState interface. In a switch world, you'd be adding a case to each switch.

Each time you add a new behaviour, you need to add a new method to the IState interface, and each of the implementations. This is the same burden as before, though now the compiler will check that you have implementations of the new behaviour on each pre-existing state.

Others have said already, that this may be too heavyweight, so of course there is a point you reach where you move from one to another. Personally, the second time I write a switch is the point at which I refactor.

If you have a query with a lot of criteria, it can be tricky to remember what each one does. I add a text field into the original table - call it "comments" or "documentation". Then I include it in the query with a comment for each criteria.

Comments need to be written like like this so that all relevant rows are returned. Unfortunately, as I'm a new poster, I can't add a screenshot!

So here goes without

Field:   | Comment              |ContractStatus     | ProblemDealtWith | ...... |

Table:   | ElecContracts        |ElecContracts      | ElecContracts    | ...... |

Sort:  

Show:  

Criteria | <> "all problems are | "objection" Or |

         | picked up with this  | "rejected" Or  |

         | criteria" OR Is Null | "rolled"       |

         | OR ""

<> tells the query to choose rows that are not equal to the text you entered, otherwise it will only pick up fields that have text equal to your comment i.e. none!

" " enclose your comment in quotes

OR Is Null OR "" tells your query to include any rows that have no data in the comments field , otherwise it won't return anything!

Another option suggested in this blog post is setting the style of the image as style="display: block;"

What worked for me, using jQuery and tested in IE8, Chrome and Firefox, is:

$(window).bind("beforeunload",function(event) {
    if(hasChanged) return "You have unsaved changes";
});

It is important not to return anything if no prompt is required as there are differences between IE and other browser behaviours here.

This works for me

sed '/^all:/ s/$/ anotherthing/' file

The first part is a pattern to find and the second part is an ordinary sed's substitution using $ for the end of a line.

If you want to change the file during the process, use -i option

sed -i '/^all:/ s/$/ anotherthing/' file

Or you can redirect it to another file

sed '/^all:/ s/$/ anotherthing/' file > output

If you just want the content as string, then the simple solution is to use the ReadFile function from the io/ioutil package. This function returns a slice of bytes which you can easily convert to a string.

package main

import (
    "fmt"
    "io/ioutil"
)

func main() {
    b, err := ioutil.ReadFile("file.txt") // just pass the file name
    if err != nil {
        fmt.Print(err)
    }

    fmt.Println(b) // print the content as 'bytes'

    str := string(b) // convert content to a 'string'

    fmt.Println(str) // print the content as a 'string'
}

JavaScript Classes and Inheritance (ES6)

According to ES6, you can use JavaScript classes and inheritance to accomplish what you need.

JavaScript classes, introduced in ECMAScript 2015, are primarily syntactical sugar over JavaScript's existing prototype-based inheritance.

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes

First of all, we define our abstract class. This class can't be instantiated, but can be extended. We can also define functions that must be implemented in all classes that extends this one.

/**
 * Abstract Class Animal.
 *
 * @class Animal
 */
class Animal {

  constructor() {
    if (this.constructor == Animal) {
      throw new Error("Abstract classes can't be instantiated.");
    }
  }

  say() {
    throw new Error("Method 'say()' must be implemented.");
  }

  eat() {
    console.log("eating");
  }
}

After that, we can create our concrete Classes. These classes will inherit all functions and behaviour from abstract class.

/**
 * Dog.
 *
 * @class Dog
 * @extends {Animal}
 */
class Dog extends Animal {
  say() {
    console.log("bark");
  }
}

/**
 * Cat.
 *
 * @class Cat
 * @extends {Animal}
 */
class Cat extends Animal {
  say() {
    console.log("meow");
  }
}

/**
 * Horse.
 *
 * @class Horse
 * @extends {Animal}
 */
class Horse extends Animal {}

And the results...

// RESULTS

new Dog().eat(); // eating
new Cat().eat(); // eating
new Horse().eat(); // eating

new Dog().say(); // bark
new Cat().say(); // meow
new Horse().say(); // Error: Method say() must be implemented.

new Animal(); // Error: Abstract classes can't be instantiated.

A static variable shares the value of it among all instances of the class.

Example without declaring it static:

public class Variable
{
    public int i = 5;
    public void test()
    {
        i = i + 5;
        Console.WriteLine(i);
    }
}


public class Exercise
{
    static void Main()
    {
        Variable var = new Variable();
        var.test();
        Variable var1 = new Variable();
        var1.test();
        Console.ReadKey();
    }
}

Explanation: If you look at the above example, I just declare the int variable. When I run this code the output will be 10 and 10. Its simple.

Now let's look at the static variable here; I am declaring the variable as a static.

Example with static variable:

public class Variable
{
    public static int i = 5;
    public void test()
    {
        i = i + 5;
        Console.WriteLine(i);
    }
}


public class Exercise
{
    static void Main()
    {
        Variable var = new Variable();
        var.test();
        Variable var1 = new Variable();
        var1.test();
        Console.ReadKey();
    }
}

Now when I run above code, the output will be 10 and 15. So the static variable value is shared among all instances of that class.

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

Here is an example to fully programmatically:

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

I am using the following class vars:

Spinner varSpinner;
List<String> varSpinnerData;

float varScaleX;
float varScaleY;    

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

public void renderSpinner() {


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

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

    varSpinnerData = myArraySpinner;

    Spinner mySpinner = new Spinner(varRoot);               

    varSpinner = mySpinner;

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

B - Resize and Add the Spinner to my View:

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

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


    varLayoutECommerce_Dialogue.addView(mySpinner, myParamsLayout);

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

    mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

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

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

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


        }

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

    });

}   

D - Update the Spinner with new data:

private void updateInitSpinners(){

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


     varSpinnerData.clear();

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

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

}

}

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

UPDATE:

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

private void updateInitSpinners(){

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


    varSpinnerData.clear();

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


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

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

}

}

Hope this helps......

I had a very similiar problem as I was not able to connect to TFS with my own credentials. Turned out that the user who had created the image (I was using Hyper-V) stored his account in Credential Manager. There was no way to change this in Visual Studio. To solve the issue, I opened Credential Manager in Control Panel and edited the Generic Credentials to be my own account. I closed and opened Visual Studio 2012, and reconnected to TFS. It prompted me for my credentials, but it connected with my account from then on.

hope this helps, sivilian

This is how I make it work.

My Environment:

Angular CLI Global : 6.0.0, Local: 1.7.4, Angular: 5.2, Typescript 2.5.3

Note: To enable ng Update you need to install Angular CLI 6.0 first npm install -g @angular/cli or npm install @angular/cli

1. ng update //update Angular Package core/common/complier... to 6.0.0

2. ng update @angular/cli //change angular-cli.json to angular.json

optional if you have angular-material 5.4.2, ngx-translate 9.1.1, ng-bootstrap/ng-bootstrap 1.1.1:

3. ng update @angular/material //upgrade to 6.0.1

4. npm install @ngx-translate/[email protected] --save //upgrade ngX translate to 10.0.1 for Angular 6

5 npm install --save @ng-bootstrap/[email protected] //for ng-bootstrap

If you use Observable and get the error:

ERROR in node_modules/rxjs/Observable.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/Observable'. node_modules/rxjs/observable/of.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/observable/of'.

Change: import { Observable } from "rxjs/Observable"; import { of } from 'rxjs/observable/of';

To

import { Observable, of } from "rxjs";

You can change your model method to property and use it in serializer with this approach.

class Foo(models.Model):
    . . .
    @property
    def my_field(self):
        return stuff
    . . .

class FooSerializer(ModelSerializer):
    my_field = serializers.ReadOnlyField(source='my_field')

    class Meta:
        model = Foo
        fields = ('my_field',)

Edit: With recent versions of rest framework (I tried 3.3.3), you don't need to change to property. Model method will just work fine.

This is what you want:

td {
   max-height: whatever;
   max-width: whatever;
   overflow: hidden;
}

Adding scroll="no" and style="overflow:hidden" on iframe didn't work, I had to add style="overflow:hidden" on body of html document loaded inside iframe.

function Do-SendKeys {
    param (
        $SENDKEYS,
        $WINDOWTITLE
    )
    $wshell = New-Object -ComObject wscript.shell;
    IF ($WINDOWTITLE) {$wshell.AppActivate($WINDOWTITLE)}
    Sleep 1
    IF ($SENDKEYS) {$wshell.SendKeys($SENDKEYS)}
}
Do-SendKeys -WINDOWTITLE Print -SENDKEYS '{TAB}{TAB}'
Do-SendKeys -WINDOWTITLE Print
Do-SendKeys -SENDKEYS '%{f4}'

You can still use <hr> as a horizontal line, and you probably should. In HTML5 it defines a thematic break in content, without making any promises about how it is displayed. The attributes that aren't supported in the HTML5 spec are all related to the tag's appearance. The appearance should be set in CSS, not in the HTML itself.

So use the <hr> tag without attributes, then style it in CSS to appear the way you want.

If its a Java version problem, you can edit the eclipse.ini file and assign the compatible version to the application through adding these lines:

windows example:

-vm
C:\jdk1.7.0_21\bin\javaw.exe 

for more information: https://wiki.eclipse.org/Eclipse.ini

In SQL Server Management Studio, go to Object Explorer > (your server) > Security > Logins and right-click New Login:

Then in the dialog box that pops up, pick the types of objects you want to see (Groups is disabled by default - check it!) and pick the location where you want to look for your objects (e.g. use Entire Directory) and then find your AD group.

You now have a regular SQL Server Login - just like when you create one for a single AD user. Give that new login the permissions on the databases it needs, and off you go!

Any member of that AD group can now login to SQL Server and use your database.

As numerous answers pointed out, the first and third way are the correct methods to get the array size, and the second way is not.

Here I expand on these answers with some usage examples.

@array_name evaluates to the length of the array = the size of the array = the number of elements in the array, when used in a scalar context.

Below are some examples of a scalar context, such as @array_name by itself inside if or unless, of in arithmetic comparisons such as == or !=.

All of these examples will work if you change @array_name to scalar(@array_name). This would make the code more explicit, but also longer and slightly less readable. Therefore, more idiomatic usage omitting scalar() is preferred here.

my @a = (undef, q{}, 0, 1);

# All of these test whether 'array' has four elements:
print q{array has four elements} if @a == 4;
print q{array has four elements} unless @a != 4;
@a == 4 and print q{array has four elements};
!(@a != 4) and print q{array has four elements};

# All of the above print:
# array has four elements

# All of these test whether array is not empty:
print q{array is not empty} if @a;
print q{array is not empty} unless !@a;
@a and print q{array is not empty};
!(!@a) and print q{array is not empty};

# All of the above print:
# array is not empty

It is a way to simplify error checking and avoid deep nested if's. For example:

do {
  // do something
  if (error) {
    break;
  }
  // do something else
  if (error) {
    break;
  }
  // etc..
} while (0);

I am answering this question after 4-5 years but best practices to do this as below

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">

   <LinearLayout
      android:id="@+id/firstLayout"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_toLeftOf="@+id/secondView"
      android:orientation="vertical"></LinearLayout>

   <View
      android:id="@+id/secondView"
      android:layout_width="0dp"
      android:layout_height="match_parent"
      android:layout_centerHorizontal="true" />

   <LinearLayout
      android:id="@+id/thirdLayout"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_toRightOf="@+id/secondView"
      android:orientation="vertical"></LinearLayout>
</RelativeLayout>

This is right approach as use of layout_weight is always heavy for UI operations. Splitting Layout equally using LinearLayout is not good practice

In case you can get all data for the data frame upfront, there is a much faster approach than appending to a data frame:

1. Create a list of dictionaries in which each dictionary corresponds to an input data row.
2. Create a data frame from this list.

I had a similar task for which appending to a data frame row by row took 30 min, and creating a data frame from a list of dictionaries completed within seconds.

rows_list = []
for row in input_rows:

        dict1 = {}
        # get input row in dictionary format
        # key = col_name
        dict1.update(blah..) 

        rows_list.append(dict1)

df = pd.DataFrame(rows_list)               

Here is a full working example using PDO and including column headers:

$query = $pdo->prepare('SELECT * FROM test WHERE id=?');
$query->execute(array($id));    
$results = $query->fetchAll(PDO::FETCH_ASSOC);
download_csv_results($results, 'test.csv'); 
exit();


function download_csv_results($results, $name)
{            
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename='. $name);
    header('Pragma: no-cache');
    header("Expires: 0");

    $outstream = fopen("php://output", "wb");    
    fputcsv($outstream, array_keys($results[0]));

    foreach($results as $result)
    {
        fputcsv($outstream, $result);
    }

    fclose($outstream);
}

Well my client side (a cshtml file) was using DataTables to display a grid (now using Infragistics control which are great). And once the user clicked on the row, I captured the row event and the date associated with that record in order to go back to the server and make additional server-side requests for trades, etc. And no - I DID NOT stringify it...

The DataTables def started as this (leaving lots of stuff out), and the click event is seen below where I PUSH onto my Json object :

    oTablePf = $('#pftable').dataTable({         // INIT CODE
             "aaData": PfJsonData,
             'aoColumnDefs': [                     
                { "sTitle": "Pf Id", "aTargets": [0] },
                { "sClass": "**td_nodedate**", "aTargets": [3] }
              ]
              });

   $("#pftable").delegate("tbody tr", "click", function (event) {   // ROW CLICK EVT!! 

        var rownum = $(this).index(); 
        var thisPfId = $(this).find('.td_pfid').text();  // Find Port Id and Node Date
        var thisDate = $(this).find('.td_nodedate').text();

         //INIT JSON DATA
        var nodeDatesJson = {
            "nodedatelist":[]
        };

         // omitting some code here...
         var dateArry = thisDate.split("/");
         var nodeDate = dateArry[2] + "-" + dateArry[0] + "-" + dateArry[1];

         nodeDatesJson.nodedatelist.push({ nodedate: nodeDate });

           getTradeContribs(thisPfId, nodeDatesJson);     // GET TRADE CONTRIBUTIONS 
    });

In my case, radio button value is fetched from database and then set into the form. Following code works for me.

$("input[name=name_of_radio_button_fields][value=" + saved_value_comes_from_database + "]").prop('checked', true);

Browsers have a process called "main thread", that is responsible for executing some JavaScript tasks, UI updates e.g.: painting, redraw, reflow, etc. JavaScript tasks are queued to a message queue and then are dispatched to the browser's main thread to be executed. When UI updates are generated while the main thread is busy, tasks are added into the message queue.

Try this:

foreach (Item item in myItemsList)
{
  if (SkipCondition) continue;
  // More stuff here
}

You could use something like this to give your button a value:

<?php
if (isset($_POST['submit'])) {
  $aSubmitVal = array_keys($_POST['submit'])[0];
  echo 'The button value is: ' . $aSubmitVal;
}
?>
<form action="/" method="post">
  <input id="someId" type="submit" name="submit[SomeValue]" value="Button name">
</form>

This will give you the string "SomeValue" as a result

First get file url/link then path, as below:

$url = Storage::disk('public')->url($filename);
$path = public_path($url);

If you want a dynamically sized array, then you should make a list. Not only will you get the .Add() functionality, but as @frode-f explains, dynamic arrays are more memory efficient and a better practice anyway.

And it's so easy to use.

Instead of your array declaration, try this:

$outItems = New-Object System.Collections.Generic.List[System.Object]

Adding items is simple.

$outItems.Add(1)
$outItems.Add("hi")

And if you really want an array when you're done, there's a function for that too.

$outItems.ToArray()

ASMX Web services can only be invoked by HTTP (traditional webservice with .asmx). While WCF Service or a WCF component can be invoked by any protocol (like http, tcp etc.) and any transport type.

Second, ASMX web services are not flexible. However, WCF Services are flexible. If you make a new version of the service then you need to just expose a new end. Therefore, services are agile and which is a very practical approach looking at the current business trends.

We develop WCF as contracts, interface, operations, and data contracts. As the developer we are more focused on the business logic services and need not worry about channel stack. WCF is a unified programming API for any kind of services so we create the service and use configuration information to set up the communication mechanism like HTTP/TCP/MSMQ etc
