Programs & Examples On #Selectedtext

you can make a jQuery onChange event to get the text from the combobox when the user select one of them:

<script>    
     $( "select" )
     .change(function () {
     var str = "";
     $( "select option:selected" ).each(function() {
     str += $( this ).text() + " ";
     });
     $('#EvaluationName').val(str);
     })
     .change();
 </script>

When you select an option, it will save the text in an Input hidde

  <input type="hidden" id="EvaluationName" name="EvaluationName" value="<?= $Evaluation ?>" />

After that, when you submit the form, just catch up the value of the input

$Evaluation = $_REQUEST['EvaluationName'];

Then you can do wathever you want with the text, for instance save it in a session variable and send it to other page. etc.

I had the same problem: Singleton or make a subclass android.os.Application?

First I tried with the Singleton but my app at some point makes a call to the browser

Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));

and the problem is that, if the handset doesn't have enough memory, most of your classes (even Singletons) are cleaned to get some memory so, when returning from the browser to my app, it crashed everytime.

Solution: put needed data inside a subclass of Application class.

If you look in the ISAPI And CGI Restrictions, and everything is already set to Allowed, then make sure that the ASP.NET v4.0.30319 handlers are even in the list. In my case they were not. This can be easy to overlook.

I added one for 32 %windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll and another for 64 bit %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll. You can name them both the same ASP.NET v4.0.30319.

Check Allow extension path to execute.

We setup wildcard DNS like they explained above. So the a record is *.yourname.com

Then all of the subdomains are actually going to the same place, but PHP treats each subdomain as a different account.

We use the following code:

$url=$_SERVER["REQUEST_URI"];
$account=str_replace(".yourdomain.com","",$url);

This code just sets the $account variable the same as the subdomain. You could then retrieve their files and other information based on their account.

This probably isn't as efficient as the ways they list above, but if you don't have access to BIND and/or limited .htaccess this method should work (as long as your host will setup the wildcard for you).

We actually use this method to connect to the customers database for a multi-company e-commerce application, but it may work for you as well.

The above solutions work fine for most cases. However, if you also need to remove all traces of that file (ie sensitive data such as passwords), you will also want to remove it from your entire commit history, as the file could still be retrieved from there.

Here is a solution that removes all traces of the file from your entire commit history, as though it never existed, yet keeps the file in place on your system.

You can actually skip to step 3 if you are in your local git repository, and don't need to perform a dry run. In my case, I only needed steps 3 and 6, as I had already created my .gitignore file, and was in the repository I wanted to work on.

To see your changes, you may need to go to the GitHub root of your repository and refresh the page. Then navigate through the links to get to an old commit that once had the file, to see that it has now been removed. For me, simply refreshing the old commit page did not show the change.

It looked intimidating at first, but really, was easy and worked like a charm ! :-)

My situation was slightly different, I did git reset HEAD~ three times.

To undo it I had to do

git reset HEAD@{3}

so you should be able to do

git reset HEAD@{N}

But if you have done git reset using

git reset HEAD~3

you will need to do

git reset HEAD@{1}

{N} represents the number of operations in reflog, as Mark pointed out in the comments.

You can add it:

var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);

...but I wouldn't be surprised if by the time that ran, the browser had already made its decisions about how to render the page.

The real answer here has to be to output the correct tag from the server in the first place. (Sadly, you can't just not have the tag if you need to support IE. :-| )

There are a few OS-specific routines for beeping.

• On a Unix-like OS, try the (n)curses beep() function. This is likely to be more portable than writing '\a' as others have suggested, although for most terminal emulators that will probably work.

• In some *BSDs there is a PC speaker device. Reading the driver source, the SPKRTONE ioctl seems to correspond to the raw hardware interface, but there also seems to be a high-level language built around write()-ing strings to the driver, described in the manpage.

• It looks like Linux has a similar driver (see this article for example; there is also some example code on this page if you scroll down a bit.).

• In Windows there is a function called Beep().

I only put this in for completeness. I've learned plenty from marius and mdml. Here are the edge weights. Sorry about the arrows. Looks like I'm not the only one saying it can't be helped. I couldn't render this with ipython notebook I had to go straight from python which was the problem with getting my edge weights in sooner.

import networkx as nx
import numpy as np
import matplotlib.pyplot as plt
import pylab

G = nx.DiGraph()

G.add_edges_from([('A', 'B'),('C','D'),('G','D')], weight=1)
G.add_edges_from([('D','A'),('D','E'),('B','D'),('D','E')], weight=2)
G.add_edges_from([('B','C'),('E','F')], weight=3)
G.add_edges_from([('C','F')], weight=4)


val_map = {'A': 1.0,
                   'D': 0.5714285714285714,
                              'H': 0.0}

values = [val_map.get(node, 0.45) for node in G.nodes()]
edge_labels=dict([((u,v,),d['weight'])
                 for u,v,d in G.edges(data=True)])
red_edges = [('C','D'),('D','A')]
edge_colors = ['black' if not edge in red_edges else 'red' for edge in G.edges()]

pos=nx.spring_layout(G)
nx.draw_networkx_edge_labels(G,pos,edge_labels=edge_labels)
nx.draw(G,pos, node_color = values, node_size=1500,edge_color=edge_colors,edge_cmap=plt.cm.Reds)
pylab.show()

You can use df.plot.scatter, and pass an array to c= argument defining the color of each point:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
colors = np.where(df["key1"]==4,'r','-')
colors[df["key1"]==6] = 'g'
colors[df["key1"]==8] = 'b'
print(colors)
df.plot.scatter(x="one",y="two",c=colors)
plt.show()

Add OSHI dependency via maven:

<dependency>
    <groupId>com.github.dblock</groupId>
    <artifactId>oshi-core</artifactId>
    <version>2.2</version>
</dependency>

Get a battery capacity left in percentage:

SystemInfo si = new SystemInfo();
HardwareAbstractionLayer hal = si.getHardware();
for (PowerSource pSource : hal.getPowerSources()) {
    System.out.println(String.format("%n %s @ %.1f%%", pSource.getName(), pSource.getRemainingCapacity() * 100d));
}

 $('input[type="radio"]').change(function(){
      if($("input[name='group']:checked")){
      $(div).show();
    }
  });

Update: You can now just right click

Right click > Save as in the Console panel to save the logged messages to a file.

Original Answer:

You can use this devtools snippet shown below to create a console.save method. It creates a FileBlob from the input, and then automatically downloads it.

(function(console){

console.save = function(data, filename){

    if(!data) {
        console.error('Console.save: No data')
        return;
    }

    if(!filename) filename = 'console.json'

    if(typeof data === "object"){
        data = JSON.stringify(data, undefined, 4)
    }

    var blob = new Blob([data], {type: 'text/json'}),
        e    = document.createEvent('MouseEvents'),
        a    = document.createElement('a')

    a.download = filename
    a.href = window.URL.createObjectURL(blob)
    a.dataset.downloadurl =  ['text/json', a.download, a.href].join(':')
    e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
    a.dispatchEvent(e)
 }
})(console)

_x000D_
//check and create an array to save parameters_x000D_

    if (param1 != null) {_x000D_
        params['param1'] = param1;_x000D_

_x000D_
//build a new url with new parameters using jQuery param_x000D_
window.location.href =  window.location.origin + window.location.pathname + '?' + $.param(params);

I used JQUERY param: http://api.jquery.com/jquery.param/ to create a new url with new parameters.

In Tomcat 6, the CLASSPATH in your environment is ignored. In setclasspath.bat you'll see

set CLASSPATH=%JAVA_HOME%\lib\tools.jar

then in catalina.bat, it's used like so

%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS% 
-Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" 
-Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" 
-Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION%

I don't see any other vars that are included, so I think you're stuck with editing setclasspath.bat and changing how CLASSPATH is built. For Tomcat 6.0.20, this change was on like 74 of setclasspath.bat

set CLASSPATH=C:\app_config\java_app;%JAVA_HOME%\lib\tools.jar

Update image field to add full URL, ignoring null fields:

UPDATE test SET image = CONCAT('https://my-site.com/images/',image) WHERE image IS NOT NULL;

Use a DecimalFormatter:

double number = 0.9999999999999;
DecimalFormat numberFormat = new DecimalFormat("#.00");
System.out.println(numberFormat.format(number));

Will give you "0.99". You can add or subtract 0 on the right side to get more or less decimals.

Or use '#' on the right to make the additional digits optional, as in with #.## (0.30) would drop the trailing 0 to become (0.3).

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

You can use btoa (to base-64) and atob (from base-64).

For IE 9 and below, try the jquery-base64 plugin:

$.base64.encode("this is a test");
$.base64.decode("dGhpcyBpcyBhIHRlc3Q=");

The asker's original inclination to use str.charCodeAt(i) appears to be faster than the regular expression alternative. In my test on jsPerf the RegExp option performs 66% slower in Chrome 36 (and slightly slower in Firefox 31).

Here's a cleaned-up version of the original validation code that receives a string and returns true or false:

function isAlphaNumeric(str) {
  var code, i, len;

  for (i = 0, len = str.length; i < len; i++) {
    code = str.charCodeAt(i);
    if (!(code > 47 && code < 58) && // numeric (0-9)
        !(code > 64 && code < 91) && // upper alpha (A-Z)
        !(code > 96 && code < 123)) { // lower alpha (a-z)
      return false;
    }
  }
  return true;
};

Of course, there may be other considerations, such as readability. A one-line regular expression is definitely prettier to look at. But if you're strictly concerned with speed, you may want to consider this alternative.

Just a note that as of Ruby 2.0 there is no need to add # encoding: utf-8. UTF-8 is automatically detected.

Note that Office Web Components are dead, see does-office-xp-web-components-compatable-with-windows-7. OWC was discontinued from XP onward for security reasons.

Since then, and only recently, Microsoft pushes Excel Web App as alternative (a poor alternative IMHO)

As a side note: Microsoft also deprecated the other way round, i.e. embedding the webbrowser control into an excel sheet, see adding-web-browser-control-to-excel-2013. As an alternative Microsoft offers Office Apps (a very limited alternative with respect to interfacing Excel and IE)

According to the React Documentation it's perfectly OK to call setState() from within the componentDidMount() function.

It will cause render() to be called twice, which is less efficient than only calling it once, but other than that it's perfectly fine.

You can find the documentation here:

https://reactjs.org/docs/react-component.html#componentdidmount

Here is the excerpt from the documentation:

You may call setState() immediately in componentDidMount(). It will trigger an extra rendering, but it will happen before the browser updates the screen. This guarantees that even though the render() will be called twice in this case, the user won’t see the intermediate state. Use this pattern with caution because it often causes performance issues...

Solution

Data file: paw.txt. Source code:

from scipy import *
from operator import itemgetter

n = 5  # how many fingers are we looking for

d = loadtxt("paw.txt")
width, height = d.shape

# Create an array where every element is a sum of 2x2 squares.

fourSums = d[:-1,:-1] + d[1:,:-1] + d[1:,1:] + d[:-1,1:]

# Find positions of the fingers.

# Pair each sum with its position number (from 0 to width*height-1),

pairs = zip(arange(width*height), fourSums.flatten())

# Sort by descending sum value, filter overlapping squares

def drop_overlapping(pairs):
    no_overlaps = []
    def does_not_overlap(p1, p2):
        i1, i2 = p1[0], p2[0]
        r1, col1 = i1 / (width-1), i1 % (width-1)
        r2, col2 = i2 / (width-1), i2 % (width-1)
        return (max(abs(r1-r2),abs(col1-col2)) >= 2)
    for p in pairs:
        if all(map(lambda prev: does_not_overlap(p,prev), no_overlaps)):
            no_overlaps.append(p)
    return no_overlaps

pairs2 = drop_overlapping(sorted(pairs, key=itemgetter(1), reverse=True))

# Take the first n with the heighest values

positions = pairs2[:n]

# Print results

print d, "\n"

for i, val in positions:
    row = i / (width-1)
    column = i % (width-1)
    print "sum = %f @ %d,%d (%d)" % (val, row, column, i)
    print d[row:row+2,column:column+2], "\n"

Output without overlapping squares. It seems that the same areas are selected as in your example.

Some comments

The tricky part is to calculate sums of all 2x2 squares. I assumed you need all of them, so there might be some overlapping. I used slices to cut the first/last columns and rows from the original 2D array, and then overlapping them all together and calculating sums.

To understand it better, imaging a 3x3 array:

>>> a = arange(9).reshape(3,3) ; a
array([[0, 1, 2],
       [3, 4, 5],
       [6, 7, 8]])

Then you can take its slices:

>>> a[:-1,:-1]
array([[0, 1],
       [3, 4]])
>>> a[1:,:-1]
array([[3, 4],
       [6, 7]])
>>> a[:-1,1:]
array([[1, 2],
       [4, 5]])
>>> a[1:,1:]
array([[4, 5],
       [7, 8]])

Now imagine you stack them one above the other and sum elements at the same positions. These sums will be exactly the same sums over the 2x2 squares with the top-left corner in the same position:

>>> sums = a[:-1,:-1] + a[1:,:-1] + a[:-1,1:] + a[1:,1:]; sums
array([[ 8, 12],
       [20, 24]])

When you have the sums over 2x2 squares, you can use max to find the maximum, or sort, or sorted to find the peaks.

To remember positions of the peaks I couple every value (the sum) with its ordinal position in a flattened array (see zip). Then I calculate row/column position again when I print the results.

Notes

I allowed for the 2x2 squares to overlap. Edited version filters out some of them such that only non-overlapping squares appear in the results.

Choosing fingers (an idea)

Another problem is how to choose what is likely to be fingers out of all the peaks. I have an idea which may or may not work. I don't have time to implement it right now, so just pseudo-code.

I noticed that if the front fingers stay on almost a perfect circle, the rear finger should be inside of that circle. Also, the front fingers are more or less equally spaced. We may try to use these heuristic properties to detect the fingers.

Pseudo code:

select the top N finger candidates (not too many, 10 or 12)
consider all possible combinations of 5 out of N (use itertools.combinations)
for each combination of 5 fingers:
    for each finger out of 5:
        fit the best circle to the remaining 4
        => position of the center, radius
        check if the selected finger is inside of the circle
        check if the remaining four are evenly spread
        (for example, consider angles from the center of the circle)
        assign some cost (penalty) to this selection of 4 peaks + a rear finger
        (consider, probably weighted:
             circle fitting error,
             if the rear finger is inside,
             variance in the spreading of the front fingers,
             total intensity of 5 peaks)
choose a combination of 4 peaks + a rear peak with the lowest penalty

This is a brute-force approach. If N is relatively small, then I think it is doable. For N=12, there are C_12^5 = 792 combinations, times 5 ways to select a rear finger, so 3960 cases to evaluate for every paw.

To return only one row use LIMIT 1:

SELECT *
FROM tbl_foo
WHERE name = 'sarmen'
LIMIT 1

It doesn't make sense to say 'first row' or 'last row' unless you have an ORDER BY clause. Assuming you add an ORDER BY clause then you can use LIMIT in the following ways:

• To get the first row use LIMIT 1.
• To get the 2nd row you can use limit with an offset: LIMIT 1, 1.
• To get the last row invert the order (change ASC to DESC or vice versa) then use LIMIT 1.

As you can't import a .txt file, I would suggest to read words this way.

list_ = open("world.txt").read().split()

if you are doing it all by code in the viewDidLoad method of the UIViewController you should only add self.title = @"title text";

something like this:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.title = @"title";
}

you could also try self.navigationItem.title = @"title";

also check if your navigationItem is not null and if you have set a custom background to the navigationbar check if the title is set without it.

I think a nice solution is with the function filter of pandas and regex (match everything except "b"):

df.filter(regex="^(?!b$)")

var _t = new Date();

if you want UTC format simply

_t.toLocaleString('indian', { timeZone: 'UTC' }).replace(/(\w+)\/(\w+)\/(\w+), (\w+)/, '$3-$2-$1 $4');

or

_t.toISOString().slice(0, 19).replace('T', ' ');

and if want in specific timezone then

_t.toLocaleString('indian', { timeZone: 'asia/kolkata' }).replace(/(\w+)\/(\w+)\/(\w+), (\w+)/, '$3-$2-$1 $4');

The syntax to grant select permission on a specific table :

USE YourDB;

GRANT SELECT ON dbo.functionName TO UserName;

To grant the select permission on all tables in the database:

USE YourDB;

GRANT SELECT TO UserName;

Try this Method

dataGridView1.DataSource = dt;
dt.Rows.Clear();

I once had this kind of problem installing MinGW to work in Windows, even after I added the right System PATH in my Environment Variables.

After days of misery, I finally stumbled on a thread that recommended uninstalling the original MinGW compiler and deleting the C:\MinGW folder and installing TDM-GCC MinGW compiler which can be found here.

You have options of choosing a 64/32-bit installer from the download page, and it creates the environment path variables for you too.

Great answers are:

• this which explain the history, and
• this gives the right citation to ease yours translation/understanding.

My note here comes from what Donald Knuth once said (sorry can't find reference) that there is a construct where while-else is indistinguishable from if-else, namely (in Python):

x = 2
while x > 3:
    print("foo")
    break
else:
    print("boo")

has the same flow (excluding low level differences) as:

x = 2
if x > 3:
    print("foo")
else:
    print("boo")

The point is that if-else can be considered as syntactic sugar for while-else which has implicit break at the end of its if block. The opposite implication, that while loop is extension to if, is more common (it's just repeated/looped conditional check), because if is often taught before while. However that isn't true because that would mean else block in while-else would be executed each time when condition is false.

To ease your understanding think of it that way:

Without break, return, etc., loop ends only when condition is no longer true and in such case else block will also execute once. In case of Python for you must consider C-style for loops (with conditions) or translate them to while.

Another note:

Premature break, return, etc. inside loop makes impossible for condition to become false because execution jumped out of the loop while condition was true and it would never come back to check it again.

One gotcha is that the following is implementation dependent (according to the ANSI standard):

char x = -1;
x >> 1;

x can now be 127 (01111111) or still -1 (11111111).

In practice, it's usually the latter.

Substring and Join methods are usable for this statement.

string no = "12345";
string [] numberArray = new string[no.Length];
int counter = 0;

   for (int i = 0; i < no.Length; i++)
   {
     numberArray[i] = no.Substring(counter, 1); // 1 is split length
     counter++;
   }

Console.WriteLine(string.Join(" ", numberArray)); //output >>> 0 1 2 3 4 5

By default node will run on every IP address exposed by the host on which it runs. You don't need to do anything special. You already knew the server runs on a particular port. You can prove this, by using that IP address on a browser on that machine:

http://my-ip-address:port

If that didn't work, you might have your IP address wrong.

Ok, I know that it's an old issue but I post my answer anyway.

I like this solution. I only have to specify the identity column(s).

SELECT * INTO TempTable FROM MyTable_T WHERE id = 1;
ALTER TABLE TempTable DROP COLUMN id;
INSERT INTO MyTable_T SELECT * FROM TempTable;
DROP TABLE TempTable;

The "id"-column is the identity column and that's the only column I have to specify. It's better than the other way around anyway. :-)

I use SQL Server. You may want to use "CREATE TABLE" and "UPDATE TABLE" at row 1 and 2. Hmm, I saw that I did not really give the answer that he wanted. He wanted to copy the id to another column also. But this solution is nice for making a copy with a new auto-id.

I edit my solution with the idéas from Michael Dibbets.

use MyDatabase; 
SELECT * INTO #TempTable FROM [MyTable] WHERE [IndexField] = :id;
ALTER TABLE #TempTable DROP COLUMN [IndexField]; 
INSERT INTO [MyTable] SELECT * FROM #TempTable; 
DROP TABLE #TempTable;

You can drop more than one column by separating them with a ",". The :id should be replaced with the id of the row you want to copy. MyDatabase, MyTable and IndexField should be replaced with your names (of course).

If the format is that simple (a space separates the number from the rest) then

int(str1.split()[0])

would do it

You can use

new File("relative/path").getAbsoluteFile()

after

System.setProperty("user.dir", "/some/directory")

System.setProperty("user.dir", "C:/OtherProject");
File file = new File("data/data.csv").getAbsoluteFile();
System.out.println(file.getPath());

Will print

C:\OtherProject\data\data.csv

As the other answers mentioned, dispatch_async from the main thread is fine.

However, depending on your use case, there is a side effect that you may consider a disadvantage: since the block is scheduled on a queue, it won't execute until control goes back to the run loop, which will have the effect of delaying your block's execution.

For example,

NSLog(@"before dispatch async");
dispatch_async(dispatch_get_main_queue(), ^{
    NSLog(@"inside dispatch async block main thread from main thread");
});
NSLog(@"after dispatch async");

Will print out:

before dispatch async
after dispatch async
inside dispatch async block main thread from main thread

For this reason, if you were expecting the block to execute in-between the outer NSLog's, dispatch_async would not help you.

**This can be achived easily using two different ways:**

1)We can also do this by using addClass and removeClass of Jquery
2)Toggle class of jQuery

**1)First Way**

$(documnet.ready(function(){
$('#dvId').click(function(){
  $('#dvId').removeClass('active class or your class name which you want to    remove').addClass('active class or your class name which you want to add');     
});
});

**2) Second Way**

i) Here we need to add the class which we want to show while page get loads.
ii)after clicking on div we we will toggle class i.e. the class is added while loading page gets removed and class which we provide in toggleClss gets added :)

<div id="dvId" class="ActiveClassname ">
</div

$(documnet.ready(function(){
$('#dvId').click(function(){
  $('#dvId').toggleClass('ActiveClassname InActiveClassName');     
});
});


Enjoy.....:)

If you any doubt free to ask any time...

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

Fitting a moving average to your data would smooth out the noise, see this this answer for how to do that.

If you'd like to use LOWESS to fit your data (it's similar to a moving average but more sophisticated), you can do that using the statsmodels library:

import numpy as np
import pylab as plt
import statsmodels.api as sm

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2
lowess = sm.nonparametric.lowess(y, x, frac=0.1)

plt.plot(x, y, '+')
plt.plot(lowess[:, 0], lowess[:, 1])
plt.show()

Finally, if you know the functional form of your signal, you could fit a curve to your data, which would probably be the best thing to do.

If your keyboard is set to English US (International) rather than English US the double quotation marks don't work. This is why the single quotation marks worked in your case.

Given your URL:

http://locahost:8000/example?a=10

The best way that I have found to get the value for 'a' and display it on the page is to use the following:

{{ request()->get('a') }}

However, if you want to use it within an if statement, you could use:

@if( request()->get('a') )
    <script>console.log('hello')</script>
@endif

Hope that helps someone! :)

Same thing, with jQuery:

$('#links a').each(function(){
    var me = $(this);
    me.html( me.text().replace(/(^\w+)/,'<strong>$1</strong>') );
  });

or

$('#links a').each(function(){
    var me = $(this)
       , t = me.text().split(' ');
    me.html( '<strong>'+t.shift()+'</strong> '+t.join(' ') );
  });

Run:

go mod init yellow

Then create a file yellow.go:

package yellow

func Mix(s string) string {
   return s + "Yellow"
}

Then create a file orange/orange.go:

package main
import "yellow"

func main() {
   s := yellow.Mix("Red")
   println(s)
}

Then build:

go build

Although the accepted answer is correct but if you are just trying to upload your image to cloudinary, there's a better way:

Map upload = cloudinary.uploader().upload(multipartFile.getBytes(), ObjectUtils.emptyMap());

Where multipartFile is your org.springframework.web.multipart.MultipartFile.

The above - findByBookIdRegion() did not work for me. The following works with the latest release of String Data JPA:

Maybe it's too late for an answer to this question but i think i have found a fix for it, what i noticed is within the info.plist file > JVMoption (Mac) with in the application package there is two version of java i.e it was showing "1.6*,1.7+" so i just changed it to "1.8*" which is my current java version and now its working for me

A slightly simpler method:

>>> t = ((1, 'a'),(2, 'b'))
>>> dict(map(reversed, t))
{'a': 1, 'b': 2}

Although this question has an accepted answer but I think this is a much cleaner way to achieve the desired output

<select required>
<option value="">Select</option>
<option>English</option>
<option>Spanish</option>
</select>

The required attribute in makes it mandatory to select an option from the list.

value="" inside the option tag combined with the required attribute in select tag makes selection of 'Select' option not permissible, thus achieving the required output

The legacy solution, before 1.6, was to use .attr and handle the returned value as a bool. The main problem is that the returned type of .attr has changed to string, and therefore the comparison with == true is broken (see http://jsfiddle.net/2vene/1/ (and switch the jquery-version)).

With 1.6 .prop was introduced, which returns a bool.

Nevertheless, I suggest to use .is(), as the returned type is intrinsically bool, like:

$('#dropUnit').is(':disabled');
$('#dropUnit').is(':enabled');

Furthermore .is() is much more natural (in terms of "natural language") and adds more conditions than a simple attribute-comparison (eg: .is(':last'), .is(':visible'), ... please see documentation on selectors).

To make it with jquery, make this way:

var test = $("input[name=testing]:hidden");
test.val('work!');

Or

var test = $("input[name=testing]:hidden").val('work!');

See working in this fiddle.

Used this approach for array of bytes:

Initially:

byte[] bytes = new byte[0];

Whenever required (Need to provide original length for extending):

Array.Resize<byte>(ref bytes, bytes.Length + requiredSize);

Reset:

Array.Resize<byte>(ref bytes, 0);

Typed List Method

Initially:

List<byte> bytes = new List<byte>();

Whenever required:

bytes.AddRange(new byte[length]);

Release/Clear:

bytes.Clear()

My scenario; i had to use the remote server as a bastion host to connect elsewhere. Final Destination/Target: 169.254.76.1, port 8890. Through intermediary server with public ip: ec2-54-162-180-7.compute-1.amazonaws.com

SSH local port forwarding command:

ssh -i ~/keys/dev.tst -vnNT -L :8890:169.254.76.1:8890

What the problem was: There was no service bound on port 8890 in the target host. i had forgotten to start the service.

How did i trouble shoot:

SSH into bastion host and then do curl.

Hope this helps.

Using all built-ins..

tuple(map(sum, zip(a, b)))

you have to do some changes by applying group by or query with in query.

"SELECT CITY,LENGTH(CITY) FROM STATION ORDER BY LENGTH(CITY) DESC LIMIT 1;"

it will return longest cityname from city.

MediaWiki's API is running on Wikipedia (docs). You can also use the Special:Export feature to dump data and parse it yourself.

More information.

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

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

To use inArray within an if statement use:

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

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

df --output=avail -B 1 "$PWD" |tail -n 1

you get size in bytes this way.

To conditionally check the length of the string, use CASE.

SELECT  CASE WHEN LEN(comments) <= 60 
             THEN comments
             ELSE LEFT(comments, 60) + '...'
        END  As Comments
FROM    myView

You can only use switch-case on types castable to an int.

You could, however, define a std::map<std::string, std::function> dispatcher and use it like dispatcher[str]() to achieve same effect.

Boost is a good suggestion. But if you would like to roll your own, it's not so hard.

Basically you just need a way to build up a graph of objects and then output them to some structured storage format (JSON, XML, YAML, whatever). Building up the graph is as simple as utilizing a marking recursive decent object algorithm and then outputting all the marked objects.

I wrote an article describing a rudimentary (but still powerful) serialization system. You may find it interesting: Using SQLite as an On-disk File Format, Part 2.

There are following ways to persist container data:

1. Docker volumes

2. Docker commit

   a) create container from ubuntu image and run a bash terminal.

      $ docker run -i -t ubuntu:14.04 /bin/bash
   

   b) Inside the terminal install curl

      # apt-get update
      # apt-get install curl
   

   c) Exit the container terminal

      # exit
   

   d) Take a note of your container id by executing following command :

      $ docker ps -a
   

   e) save container as new image

      $ docker commit <container_id> new_image_name:tag_name(optional)
   

   f) verify that you can see your new image with curl installed.

      $ docker images           
   
      $ docker run -it new_image_name:tag_name bash
         # which curl
           /usr/bin/curl
   

Do this: Step 1: Your String

String str = ";;;;;;\n" +
            "Name, number, address;;;;;;\n" + 
             "01.01.12-16.02.12;;;;;;\n" + 
             ";;;;;;\n" + 
             ";;;;;;";

Step 2: Just replace all "\n" with "%n" the result looks like this

String str = ";;;;;;%n" +
             "Name, number, address;;;;;;%n" + 
             "01.01.12-16.02.12;;;;;;%n" + 
            ";;;;;;%n" + 
            ";;;;;;";

Notice I've just put "%n" in place of "\n"

Step 3: Now simply call format()

str=String.format(str);

That's all you have to do.

Be consistent with the API(s) you're using.

Just a quick note (and possible cause).

You can have a perfectly correct VirtualHost setup with _default_:443 etc. in your Apache .conf file.

But... If there is even one .conf file enabled with incorrect settings that also listens to port 443, then it will bring the whole SSL system down.

Therefore, if you are sure your .conf file is correct, try disabling the other site .conf files in sites-enabled.

Be aware of that if you use nested transactions, a ROLLBACK operation rolls back all the nested transactions including the outer-most one.

This might, with usage in combination with TRY/CATCH, result in the error you described. See more here.

Further to Karl Anderson solution, you could put your parameters into session information and then clear them after response.TransmitFile(Server.MapPath( Session(currentSessionItemName)));.

See MSDN page HttpSessionState.Add Method (String, Object) for more information on sessions.

I interpreted the question as using cast on a subquery. Yes, you can do that:

select cast((<subquery>) as <newtype>)

If you do so, then you need to be sure that the returns one row and one value. And, since it returns one value, you could put the cast in the subquery instead:

select (select cast(<val> as <newtype>) . . .)

You need to reverse the nesting inside the generate block:

genvar c;
generate
    for (c = 0; c < ROWBITS; c = c + 1) begin: test
        always @(posedge sysclk) begin
            temp[c] <= 1'b0;
        end
    end
endgenerate

Technically, this generates four always blocks:

always @(posedge sysclk) temp[0] <= 1'b0;
always @(posedge sysclk) temp[1] <= 1'b0;
always @(posedge sysclk) temp[2] <= 1'b0;
always @(posedge sysclk) temp[3] <= 1'b0;

In this simple example, there's no difference in behavior between the four always blocks and a single always block containing four assignments, but in other cases there could be.

The genvar-dependent operation needs to be resolved when constructing the in-memory representation of the design (in the case of a simulator) or when mapping to logic gates (in the case of a synthesis tool). The always @posedge doesn't have meaning until the design is operating.

Subject to certain restrictions, you can put a for loop inside the always block, even for synthesizable code. For synthesis, the loop will be unrolled. However, in that case, the for loop needs to work with a reg, integer, or similar. It can't use a genvar, because having the for loop inside the always block describes an operation that occurs at each edge of the clock, not an operation that can be expanded statically during elaboration of the design.

The official way to install Popper.js is trough npm, Yarn or NuGet.

Use either one of the following commands :

npm i popper.js
yarn add popper.js
PM> Install-Package popper.js

Everything is described in the library readme.

Regarding the "downloads the zip", the zip clearly states that it contains the source code of the library.

Edit:

Starting from version 1.12.0, Popper.js is available as Bower dependency.

This installation method is going to be supported only for the 1.x version of Popper.js and will be removed in 2.x.

You should migrate your dependencies management to a modern system like npm or Yarn, as Bower suggests as well.

Though this post is old and has had an answer accepted, using reloadOnSeach=false does not solve the problem for those of us who need to change actual path and not just the params. Here's a simple solution to consider:

Use ng-include instead of ng-view and assign your controller in the template.

<!-- In your index.html - instead of using ng-view -->
<div ng-include="templateUrl"></div>

<!-- In your template specified by app.config -->
<div ng-controller="MyController">{{variableInMyController}}</div>

//in config
$routeProvider
  .when('/my/page/route/:id', { 
    templateUrl: 'myPage.html', 
  })

//in top level controller with $route injected
$scope.templateUrl = ''

$scope.$on('$routeChangeSuccess',function(){
  $scope.templateUrl = $route.current.templateUrl;
})

//in controller that doesn't reload
$scope.$on('$routeChangeSuccess',function(){
  //update your scope based on new $routeParams
})

Only down-side is that you cannot use resolve attribute, but that's pretty easy to get around. Also you have to manage the state of the controller, like logic based on $routeParams as the route changes within the controller as the corresponding url changes.

Here's an example: http://plnkr.co/edit/WtAOm59CFcjafMmxBVOP?p=preview

This is a server side issue. You don't need to add any headers in angular for cors. You need to add header on the server side:

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

First two answers here: How to enable CORS in AngularJs

Visibility is an animatable property according to the spec, but transitions on visibility do not work gradually, as one might expect. Instead transitions on visibility delay hiding an element. On the other hand making an element visible works immediately. This is as it is defined by the spec (in the case of the default timing function) and as it is implemented in the browsers.

This also is a useful behavior, since in fact one can imagine various visual effects to hide an element. Fading out an element is just one kind of visual effect that is specified using opacity. Other visual effects might move away the element using e.g. the transform property, also see http://taccgl.org/blog/css-transition-visibility.html

It is often useful to combine the opacity transition with a visibility transition! Although opacity appears to do the right thing, fully transparent elements (with opacity:0) still receive mouse events. So e.g. links on an element that was faded out with an opacity transition alone, still respond to clicks (although not visible) and links behind the faded element do not work (although being visible through the faded element). See http://taccgl.org/blog/css-transition-opacity-for-fade-effects.html.

This strange behavior can be avoided by just using both transitions, the transition on visibility and the transition on opacity. Thereby the visibility property is used to disable mouse events for the element while opacity is used for the visual effect. However care must be taken not to hide the element while the visual effect is playing, which would otherwise not be visible. Here the special semantics of the visibility transition becomes handy. When hiding an element the element stays visible while playing the visual effect and is hidden afterwards. On the other hand when revealing an element, the visibility transition makes the element visible immediately, i.e. before playing the visual effect.

Basically I use Fiddler or Postman for testing API's.

In fiddler, in request header you need to specify instead of xml, html you need to change it to json. Eg: Accept: application/json. That should do the job.

See http://caniuse.com/#search=minlength. Some browsers may not support this attribute.

If the value of the "type" is one of them:

text, email, search, password, tel, or URL (warning: not include number | no browser support "tel" now - 2017.10)

Use the minlength(/ maxlength) attribute. It specifies the minimum number of characters.

For example,

<input type="text" minlength="11" maxlength="11" pattern="[0-9]*" placeholder="input your phone number">

Or use the "pattern" attribute:

<input type="text" pattern="[0-9]{11}" placeholder="input your phone number">

If the "type" is number, although minlength(/ maxlength) is not be supported, you can use the min(/ max) attribute instead of it.

For example,

<input type="number" min="100" max="999" placeholder="input a three-digit number">

Bill Parker is getting voted down, because his definitions are reversed from the normal code convention. Normally, true is defined as 0 and false is defined as nonzero. 1 will work for false, as will 9999 and -1. The same with function return values - 0 is success and anything nonzero is failure. Sorry, I don't have the street credibility yet to vote or to reply to him directly.

Bash recommends using double brackets now as a habit instead of single brackets, and the link Mike Holt gave explains the differences in how they work. 7.3. Other Comparison Operators

For one thing, -eq is a numerical operator, so having the code

#**** NOTE *** This gives error message *****
The_world_is_flat=0;
if [ "${The_world_is_flat}" -eq true ]; then

will issue an error statement, expecting an integer expression. This applies to either parameter, as neither is an integer value. Yet, if we put double brackets around it, it will not issue an error statement, but it will yield a wrong value (well, in 50% of the possible permutations). It will evaluate to [[0 -eq true]] = success, but also to [[0 -eq false]] = success, which is wrong (hmmm.... what about that builtin being a numerical value?).

#**** NOTE *** This gives wrong output *****
The_world_is_flat=true;
if [[ "${The_world_is_flat}" -eq true ]]; then

There are other permutations of the conditional which will give wrong output as well. Basically, anything (other than the error condition listed above) that sets a variable to a numerical value and compares it to a true/false builtin, or sets a variable to a true/false builtin and compares it to a numerical value. Also, anything that sets a variable to a true/false builtin and does a comparison using -eq. So avoid -eq for Boolean comparisons and avoid using numerical values for Boolean comparisons. Here's a summary of the permutations that will give invalid results:

# With variable set as an integer and evaluating to true/false
# *** This will issue error warning and not run: *****
The_world_is_flat=0;
if [ "${The_world_is_flat}" -eq true ]; then

# With variable set as an integer and evaluating to true/false
# *** These statements will not evaluate properly: *****
The_world_is_flat=0;
if [ "${The_world_is_flat}" -eq true ]; then
#
if [[ "${The_world_is_flat}" -eq true ]]; then
#
if [ "${The_world_is_flat}" = true ]; then
#
if [[ "${The_world_is_flat}" = true ]]; then
#
if [ "${The_world_is_flat}" == true ]; then
#
if [[ "${The_world_is_flat}" == true ]]; then


# With variable set as an true/false builtin and evaluating to true/false
# *** These statements will not evaluate properly: *****
The_world_is_flat=true;
if [[ "${The_world_is_flat}" -eq true ]]; then
#
if [ "${The_world_is_flat}" = 0 ]; then
#
if [[ "${The_world_is_flat}" = 0 ]]; then
#
if [ "${The_world_is_flat}" == 0 ]; then
#
if [[ "${The_world_is_flat}" == 0 ]]; then

So, now to what works. Use true/false builtins for both your comparison and your evaluations (as Mike Hunt noted, don't enclose them in quotes). Then use either or single or double equal sign (= or ==) and either single or double brackets ([ ] or [[ ]]). Personally, I like the double equals sign, because it reminds me of logical comparisons in other programming languages, and double quotes just because I like typing. So these work:

# With variable set as an integer and evaluating to true/false
# *** These statements will work properly: *****
#
The_world_is_flat=true/false;
if [ "${The_world_is_flat}" = true ]; then
#
if [[ "${The_world_is_flat}" = true ]]; then
#
if [ "${The_world_is_flat}" = true ]; then
#
if [[ "${The_world_is_flat}" == true ]]; then

There you have it.

Use the timestamp you get by calling valueOf on the date object:

var diff = date2.valueOf() - date1.valueOf();
var diffInHours = diff/1000/60/60; // Convert milliseconds to hours

As Drake states this could be done with FileReader. However, what I present here is a functional version. Take in consideration that the big problem with doing this with JavaScript is to reset the input file. Well, this restricts to only JPG (for other formats you will have to change the mime type and the magic number):

<form id="form-id">
  <input type="file" id="input-id" accept="image/jpeg"/>
</form>

<script type="text/javascript">
    $(function(){
        $("#input-id").on('change', function(event) {
            var file = event.target.files[0];
            if(file.size>=2*1024*1024) {
                alert("JPG images of maximum 2MB");
                $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                return;
            }

            if(!file.type.match('image/jp.*')) {
                alert("only JPG images");
                $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                return;
            }

            var fileReader = new FileReader();
            fileReader.onload = function(e) {
                var int32View = new Uint8Array(e.target.result);
                //verify the magic number
                // for JPG is 0xFF 0xD8 0xFF 0xE0 (see https://en.wikipedia.org/wiki/List_of_file_signatures)
                if(int32View.length>4 && int32View[0]==0xFF && int32View[1]==0xD8 && int32View[2]==0xFF && int32View[3]==0xE0) {
                    alert("ok!");
                } else {
                    alert("only valid JPG images");
                    $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                    return;
                }
            };
            fileReader.readAsArrayBuffer(file);
        });
    });
</script>

Take in consideration that this was tested on latest versions of Firefox and Chrome, and on IExplore 10.

For a complete list of mime types see Wikipedia.

For a complete list of magic number see Wikipedia.

There are a few ways depending on some data rules that you have not included, but here is one way using what you gave.

SELECT
    t1.Field1,
    t2.Field2
FROM Table1 t1
    LEFT JOIN Table1 t2 ON t1.FK = t2.FK AND t2.Field1 IS NULL

Another way:

SELECT
    t1.Field1,
    (SELECT Field2 FROM Table2 t2 WHERE t2.FK = t1.FK AND Field1 IS NULL) AS Field2
FROM Table1 t1

Regarding the question 'can R help me find the best fitting model', there is probably a function to do this, assuming you can state the set of models to test, but this would be a good first approach for the set of n-1 degree polynomials:

polyfit <- function(i) x <- AIC(lm(y~poly(x,i)))
as.integer(optimize(polyfit,interval = c(1,length(x)-1))$minimum)

Notes

• The validity of this approach will depend on your objectives, the assumptions of optimize() and AIC() and if AIC is the criterion that you want to use,

• polyfit() may not have a single minimum. check this with something like:

  for (i in 2:length(x)-1) print(polyfit(i))
  

• I used the as.integer() function because it is not clear to me how I would interpret a non-integer polynomial.

• for testing an arbitrary set of mathematical equations, consider the 'Eureqa' program reviewed by Andrew Gelman here

Update

Also see the stepAIC function (in the MASS package) to automate model selection.

Sometimes, this error occurs when you're trying to target an element that is wrapped in a condition, for example: <div *ngIf="canShow"> <p #target>Targeted Element</p></div>

In this code, if canShow is false on render, Angular won't be able to get that element as it won't be rendered, hence the error that comes up.

One of the solutions is to use a display: hidden on the element instead of the *ngIf so the element gets rendered but is hidden until your condition is fulfilled.

I use simple grep inside function in bash script to receive properties from .properties file.

This properties file I use in two places - to setup dev environment and as application parameters.

I believe that grep may work slow in big loops but it solves my needs when I want to prepare dev environment.

Hope, someone will find this useful.

Example:

File: setup.sh

#!/bin/bash

ENV=${1:-dev}

function prop {
    grep "${1}" env/${ENV}.properties|cut -d'=' -f2
}

docker create \
    --name=myapp-storage \

    -e STORAGE_SECRET_KEY="$(prop 'app.storage.secret-key')" \
    -e STORAGE_BUCKET="$(prop 'app.storage.bucket')" \
    -v "$(prop 'app.data-path')/storage":/app/storage \
    myapp-storage:latest

You should use:

[UIApplication sharedApplication].window.rootViewController;

When there is a uiactionsheet on [UIApplication sharedApplication].keyWindow, it is not right to use keyWindow as mentioned in this answer.

on sql 2008 this is valid

DECLARE @myVariable nvarchar(Max) = 'John said to Emily "Hey there Emily"'
select @myVariable

on sql server 2005, you need to do this

DECLARE @myVariable nvarchar(Max) 
select @myVariable = 'John said to Emily "Hey there Emily"'
select @myVariable

you have to create an entry inside res/menu,override onCreateOptionsMenu and inflate it

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.yourentry, menu);
    return true;
}

an entry for the menu could be:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_cart"
        android:icon="@drawable/cart"

Kotlin version:

fun okHttpClientFactory(): OkHttpClient {
    return OkHttpClient().newBuilder()
        .addInterceptor { chain ->
            chain.request().newBuilder()
                .addHeader(HEADER_AUTHONRIZATION, O_AUTH_AUTHENTICATION)
                .build()
                .let(chain::proceed)
        }
        .build()
}

You can use, contentEquals() function. It may help you..

$(this).parent().parent().attr('id');

Is how you would get the id of the parent's parent.

EDIT:

$(this).closest('ul').attr('id');

Is a more foolproof solution for your case.

An authority is a portion of a URI. Your error suggests that it was not expecting one. The authority section is shown below, it is what is known as the website part of the url.

From RFC3986 on URIs:

The following is an example URI and its component parts:

     foo://example.com:8042/over/there?name=ferret#nose
     \_/   \______________/\_________/ \_________/ \__/
      |           |            |            |        |
   scheme     authority       path        query   fragment
      |   _____________________|__
     / \ /                        \
     urn:example:animal:ferret:nose

So there are two formats, one with an authority and one not. Regarding slashes:

"When authority is not present, the path cannot begin with two slash
characters ("//")."

Source: https://tools.ietf.org/rfc/rfc3986.txt (search for text 'authority is not present, the path cannot begin with two slash')

If you are using font awesome icons, then you can use this:

To import font-awesome:

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">

Usage:

Current Price: <i class="fa fa-inr"></i> 400.00

will show as:

VAR1=value1 VAR2=value2 myScript args ...

In Class1:

Class2 inst = new Class2();
inst.UpdateEmployee();

Maybe a bit late, but may help other people with the same question like I did.

You can use setTargetFragment on Dialog before showing, and in dialog you can call getTargetFragment to get the reference.

You cannot do that in Standard C++.

I'm posting this because it is the only correct answer. Your question asks how to do it in C++. Well, you can't do it in C++. You can do it in Windows, POSIX, Linux, Android, but all those are OS-specific solutions and not part of the language standard.

Standard C++ does not have a networking layer at all.

I assume you have this wrong assumption that C++ Standard defines the same scope of features as other language standards, Java. While Java might have built-in networking (and even a GUI framework) in the language's own standard library, C++ does not.

While there are third-party APIs and libraries which can be used by a C++ program, this is in no way the same as saying that you can do it in C++.

Here is an example to clarify what I mean. You can open a file in C++ because it has an fstream class as part of its standard library. This is not the same thing as using CreateFile(), which is a Windows-specific function and available only for WINAPI.

try:

normed = [i/sum(raw) for i in raw]

normed
[0.25, 0.5, 0.25]

There is an elegant answer already but I find that its hard to read so I made my own function. For my purposes I didn't need a negative result but it wouldn't be hard to modify.

    var subtractMonths = function (date1,date2) {
        if (date1-date2 <=0) {
            return 0;
        }
        var monthCount = 0;
        while (date1 > date2){
            monthCount++;
            date1.setMonth(date1.getMonth() -1);
        }
        return monthCount;
    }

var textToFind = 'Google';

var dd = document.getElementById('MyDropDown');
for (var i = 0; i < dd.options.length; i++) {
    if (dd.options[i].text === textToFind) {
        dd.selectedIndex = i;
        break;
    }
}

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

You can use following code which generate pdf file in background as like on button click and then would popup in brwoser with SaveAs and cancel option.

Warning[] warnings;
        string[] streamIds;
        string mimeType = string.Empty;
        string encoding = string.Empty;`enter code here`
        string extension = string.Empty;
        DataSet dsGrpSum, dsActPlan, dsProfitDetails,
            dsProfitSum, dsSumHeader, dsDetailsHeader, dsBudCom = null;

    enter code here

//This is optional if you have parameter then you can add parameters as much as you want
ReportParameter[] param = new ReportParameter[5];
            param[0] = new ReportParameter("Report_Parameter_0", "1st Para", true);
            param[1] = new ReportParameter("Report_Parameter_1", "2nd Para", true);
            param[2] = new ReportParameter("Report_Parameter_2", "3rd Para", true);
            param[3] = new ReportParameter("Report_Parameter_3", "4th Para", true);

            DataSet  dsData= "Fill this dataset with your data";
            ReportDataSource rdsAct = new ReportDataSource("RptActDataSet_usp_GroupAccntDetails", dsActPlan.Tables[0]);
            ReportViewer viewer = new ReportViewer();
            viewer.LocalReport.Refresh();
            viewer.LocalReport.ReportPath = "Reports/AcctPlan.rdlc"; //This is your rdlc name.
            viewer.LocalReport.SetParameters(param);
            viewer.LocalReport.DataSources.Add(rdsAct); // Add  datasource here         
            byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
            // byte[] bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
            // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.          
            // System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.Buffer = true;
            Response.Clear();
            Response.ContentType = mimeType;
            Response.AddHeader("content-disposition", "attachment; filename= filename" + "." + extension);
            Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file  
            Response.Flush(); // send it to the client to download  
            Response.End();

You can use functionality called Export Data-Tier Application which generates .bacpac file consisting database schema and data.

On destination server, you can use Import Data-Tier Application option which creates and populates new database from pre-created .bacpac file

If you want just to transfer database schema, you can use Extract Data-Tier Application for creating file and Deploy Data-Tier Application for deploying created database schema.

I've tried this process on different versions of SQL Server from SQL 2014 to SQL 2012 and from SQL 2014 to SQL 2008R2 and worked well.

You can configure a proxy with conda by adding it to the .condarc, like

proxy_servers:
    http: http://user:[email protected]:8080
    https: https://user:[email protected]:8080

or set the HTTP_PROXY and HTTPS_PROXY environment variables. Note that in your case you need to add the scheme to the proxy url, like https://proxy-us.bla.com:123.

See http://conda.pydata.org/docs/config.html#configure-conda-for-use-behind-a-proxy-server.

Go to Window → Preferences → Java → Installed JREs. Select the JRE you're using, click Edit, and there will be a line for Default VM Arguments which will apply to every execution. For instance, I use this on OS X to hide the icon from the dock, increase max memory and turn on assertions:

-Xmx512m -ea -Djava.awt.headless=true

I would think of one more case when pessimistic locking would be a better choice.

For optimistic locking every participant in data modification must agree in using this kind of locking. But if someone modifies the data without taking care about the version column, this will spoil the whole idea of the optimistic locking.

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

afaik to make a request to information_schema you need privileges. If you need simple list of keys you can use this command:

SHOW INDEXES IN <tablename>

this is my solution, you can set on an item (or a group) and deselect it with another click:

 private final ArrayList<Integer> seleccionados = new ArrayList<>();
@Override
    public void onBindViewHolder(final ViewHolder viewHolder, final int i) {
        viewHolder.san.setText(android_versions.get(i).getAndroid_version_name());
        if (!seleccionados.contains(i)){ 
            viewHolder.inside.setCardBackgroundColor(Color.LTGRAY);
        }
        else {
            viewHolder.inside.setCardBackgroundColor(Color.BLUE);
        }
        viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (seleccionados.contains(i)){
                    seleccionados.remove(seleccionados.indexOf(i)); 
                    viewHolder.inside.setCardBackgroundColor(Color.LTGRAY);
                } else { 
                    seleccionados.add(i);
                    viewHolder.inside.setCardBackgroundColor(Color.BLUE);
                }
            }
        });
    }

I have contact form in footer that always displays and also some pages, like Create Account, can have captcha too, so it's dynamically and I'm using next way with jQuery:

html:

<div class="g-recaptcha" id="g-recaptcha"></div>

<div class="g-recaptcha" id="g-recaptcha-footer"></div>

javascript

<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit&hl=en"></script>
<script type="text/javascript">
  var CaptchaCallback = function(){        
      $('.g-recaptcha').each(function(){
        grecaptcha.render(this,{'sitekey' : 'your_site_key'});
      })
  };
</script>

I ended up using this handy macro:

#define STRING(value)               [@(value) stringValue]

With my now ageing Borland C++ Builder compiler enums can be 1,2 or 4 bytes, although it does have a flag you can flip to force it to use ints.

I guess it's compiler specific.

Have a look at Shutterbug, Applidium's lightweight SDWebImage (a nice library on iOS) port to Android. It supports asynchronous caching, stores failed URLs, handles concurrency well, and helpful subclasses are included.

Pull requests (and bug reports) are welcome, too!

It indeed sets the stack size on a JVM.

You should touch it in either of these two situations:

• StackOverflowError (the stack size is greater than the limit), increase the value
• OutOfMemoryError: unable to create new native thread (too many threads, each thread has a large stack), decrease it.

The latter usually comes when your Xss is set too large - then you need to balance it (testing!)

I think this confusing exception occurs when you use a variable in a lambda which is a null-reference at run-time. In your case, I would check if your variable calculationViewModel is a null-reference.

Something like:

public ActionResult MNPurchase()
{
    CalculationViewModel calculationViewModel = (CalculationViewModel)TempData["calculationViewModel"];

    if (calculationViewModel != null)
    {
        decimal OP = landTitleUnitOfWork.Sales.Find()
            .Where(x => x.Min >= calculationViewModel.SalesPrice)
            .FirstOrDefault()
            .OP;

        decimal MP = landTitleUnitOfWork.Sales.Find()
            .Where(x => x.Min >= calculationViewModel.MortgageAmount)
            .FirstOrDefault()
            .MP;

        calculationViewModel.LoanAmount = (OP + 100) - MP;
        calculationViewModel.LendersTitleInsurance = (calculationViewModel.LoanAmount + 850);

        return View(calculationViewModel);
    }
    else
    {
        // Do something else...
    }
}

The standard way is to use audio/mpeg which is something like this in your PHP header function ...

header('Content-Type: audio/mpeg');

Include jquery.js and if it is included, load it before any other JavaScript code.

WAMP server generally provide addond for different php/mysql versions. However you mentioned you have downloaded latest wamp server. As of now, latest Wamp server v2.5 provide PHP version 5.5.12

So you need to upgrade it manually as follow:

1. Download binaries on php.net
2. Extract all files in a new folder : C:/wamp/bin/php/php5.5.27/
3. Copy the wampserver.conf from another php folder (like php/php5.5.12/) to the new folder
4. Rename php.ini-development file to phpForApache.ini
5. Done ! Restart WampServer (>Right Mouseclick on trayicon >Exit)

Although not asked, I'd recommend to vagrant/puppet or docker for local development. Check puphpet.com for details. It has slight learning curve but it will give you much better control of different versions of every tool.

I've faced this same problem recently and came across to this thread but my problem was with React App. Below changes in the node start command solved my issues.

Syntax

node --max-old-space-size=<size> path-to/fileName.js

Example

node --max-old-space-size=16000 scripts/build.js

Why size is 16000 in max-old-space-size?

Basically, it varies depends on the allocated memory to that thread and your node settings.

How to verify and give right size?

This is basically stay in our engine v8. below code helps you to understand the Heap Size of your local node v8 engine.

const v8 = require('v8');
const totalHeapSize = v8.getHeapStatistics().total_available_size;
const totalHeapSizeGb = (totalHeapSize / 1024 / 1024 / 1024).toFixed(2);
console.log('totalHeapSizeGb: ', totalHeapSizeGb);

Click the "activity monitor" icon in the toolbar.

From Thorsten's comment:

In SQL Server Management Studio, right click on Server, choose "Activity Monitor" from context menu -or- use keyboard shortcut Ctrl + Alt + A.

Starting from visual studio 2017 Microsoft is no longer offering .ISO images. For the new visual studio 2017 you have to download vs_community.exe from here and create an offline instalation folder:

vs_community.exe --layout c:\vs2017offline

Then, in order to install from that folder you have to first install certificates from \certificates in the download folder and then run the installation.

You can add some ALT+Letter shortcuts to the VBA editor environment. I added ALT+C to Comment selected text lines and A+X to Uncomment selected text lines:

1. In the VBE, right-click on a toolbar and select Customize
2. Optionally create a new toolbar
3. Select the Command Tab and 'Edit' in the Categories listbox. Find 'Comment Block' in the Commands listbox. Click and drag it to the target toolbar. Left-click on it to open the context popup menu and select 'Image and Text'. Replace the name with &C.
4. Repeat step 3 for the Uncomment Block command and replace the name with &X.
5. Close the Customize popup window.

There are built-in Alt+Letter commands that cannot be used for new shortcuts using letters: A,D,E,D,H,I,O,Q,R,T,V,W.

Assuming you're using bash

#!/bin/bash

current_dir=$(pwd)
script_dir=$(dirname "$0")

echo $current_dir
echo $script_dir

This script should print the directory that you're in, and then the directory the script is in. For example, when calling it from / with the script in /home/mez/, it outputs

/
/home/mez

Remember, when assigning variables from the output of a command, wrap the command in $( and ) - or you won't get the desired output.

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

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

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

OPCV3 is set earlier in my utilities code like this:

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

Can't add a comment to the solution but that didn't work for me. The solution that worked for me was to use:

var des = (MyClass)Newtonsoft.Json.JsonConvert.DeserializeObject(response, typeof(MyClass)); 
return des.data.Count.ToString();

Deserializing JSON array into strongly typed .NET object

If you just want to use the symmetrical hidden/shown directives that AngularJS came with, I suggest writing an attribute directive to simplify the templates like so (tested with Angular 7):

import { Directive, Input, HostBinding } from '@angular/core';

@Directive({ selector: '[shown]' })
export class ShownDirective {
  @Input() public shown: boolean;

  @HostBinding('attr.hidden')
  public get attrHidden(): string | null {
    return this.shown ? null : 'hidden';
  }
}

Many of the other solutions are correct. You should use *ngIf where ever possible. Using the hidden attribute can have unexpected styles applied, but unless you are writing components for others, you probably know if it is. So for this shown directive to work, you will also want to make sure that you add:

[hidden]: {
  display: none !important;
}

to your global styles somewhere.

With these you can use the directive like so:

<div [shown]="myVar">stuff</div>

with the symmetrical (and opposite) version like so:

<div [hidden]="myVar">stuff</div>

To add on to the shoulds - yous should also us a prefix like so [acmeShown] vs just [shown].

The main reason I used a shown attribute directive is for converting AngularJS code to Angular -AND- when the content that is being hidden contains container components that cause XHR round trips. The reason I don't just use [hidden]="!myVar" is that often enough it is more complicated like: [hidden]="!(myVar || yourVar) && anotherVar" - yes I can invert that, but it is more error prone.[shown]` is simply easier to think about.

Worked liked a charm for me:

matplotlib.rcParams['figure.figsize'] = (20, 10)

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--example', nargs='?', const=1, type=int)
args = parser.parse_args()
print(args)

% test.py 
Namespace(example=None)
% test.py --example
Namespace(example=1)
% test.py --example 2
Namespace(example=2)

• nargs='?' means 0-or-1 arguments
• const=1 sets the default when there are 0 arguments
• type=int converts the argument to int

If you want test.py to set example to 1 even if no --example is specified, then include default=1. That is, with

parser.add_argument('--example', nargs='?', const=1, type=int, default=1)

then

% test.py 
Namespace(example=1)

On the newer versions of macOS, one also has to set java.library.path. The easiest/safest way to do that [1] is by creating ~/.sqldeveloper/<version>/sqldeveloper.conf file and populating it as such:

AddVMOption -Djava.library.path=<instant client directory>

An old thread I know but still super relevant to anyone coming across this.

Array.map has been suggested here which is an awesome method that I use all the time. Array.reduce was also mentioned...

I would personally use an Array.reduce for this use case. Why? Despite the code being slightly less clean/clear. It is a much more efficient than piping the map function to a join.

The reason for this is because Array.map has to loop over each element to return a new array with all of the names of the object in the array. Array.join then loops over the contents of array to perform the join.

You can improve the readability of jackweirdys reduce answer by using template literals to get the code on to a single line. "Supported in all modern browsers too"

// a one line answer to this question using modern JavaScript
x.reduce((a, b) => `${a.name || a}, ${b.name}`);

Solution for EF4.3

Unique UserName

Add data annotation over column as:

 [Index(IsUnique = true)]
 [MaxLength(255)] // for code-first implementations
 public string UserName{get;set;}

Unique ID , I have added decoration [Key] over my column and done. Same solution as described here: https://msdn.microsoft.com/en-gb/data/jj591583.aspx

IE:

[Key]
public int UserId{get;set;}

Alternative answers

using data annotation

[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Column("UserId")]

using mapping

  mb.Entity<User>()
            .HasKey(i => i.UserId);
        mb.User<User>()
          .Property(i => i.UserId)
          .HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity)
          .HasColumnName("UserId");

Steps :

1. Hit http://localhost/phpmyadmin/
2. Select your DB
3. Click on Operations Tab
4. There will be a tab as "Rename database to". Add new name and check Adjust privileges.
5. Click on Go.

void main() {
  int decimals = 2;
  int fac = pow(10, decimals);
  double d = 1.234567889;
  d = (d * fac).round() / fac;
  print("d: $d");
}

Prints: 1.23

def xstr(s):
    return {None:''}.get(s, s)

The formatting can be done like this (I assumed you meant HH:MM instead of HH:SS, but it's easy to change):

Time.now.strftime("%d/%m/%Y %H:%M")
#=> "14/09/2011 14:09"

Updated for the shifting:

d = DateTime.now
d.strftime("%d/%m/%Y %H:%M")
#=> "11/06/2017 18:11"
d.next_month.strftime("%d/%m/%Y %H:%M")
#=> "11/07/2017 18:11"

You need to require 'date' for this btw.

You can turn negative input into a positive number by the following:

<input type="number" onkeyup="if(this.value<0){this.value= this.value * -1}">

Sorry I know this is an old one but still felt like helping out ^_^

Maybe it's the way I read this but assuming the excel sheet 1 is called "London" and has this information; B5="Marleybone" B6="Paddington" B7="Victoria" B8="Hammersmith". And the excel sheet 2 is called "Nottingham" and has this information; C5="Alverton" C6="Annesley" C7="Arnold" C8="Askham". Then I think this code below would work. ^_^

$xlCellTypeLastCell = 11 
$startRow = 5

$excel = new-object -com excel.application
$wb = $excel.workbooks.open("C:\users\administrator\my_test.xls")

for ($i = 1; $i -le $wb.sheets.count; $i++)
    {
        $sh = $wb.Sheets.Item($i)
        $endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
        $col = $col + $i - 1
        $city = $wb.Sheets.Item($i).name
        $rangeAddress = $sh.Cells.Item($startRow, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
        $sh.Range($rangeAddress).Value2 | foreach{
            New-Object PSObject -Property @{City = $city; Area=$_}
        }
    }

$excel.Workbooks.Close()

This should be the output (without the commas):

City, Area
---- ----
London, Marleybone
London, Paddington
London, Victoria
London, Hammersmith
Nottingham, Alverton
Nottingham, Annesley
Nottingham, Arnold
Nottingham, Askham

In order to start an activity which should return result to the calling activity, you should do something like below. You should pass the requestcode as shown below in order to identify that you got the result from the activity you started.

startActivityForResult(new Intent(“YourFullyQualifiedClassName”),requestCode);

In the activity you can make use of setData() to return result.

Intent data = new Intent();
String text = "Result to be returned...."
//---set the data to pass back---
data.setData(Uri.parse(text));
setResult(RESULT_OK, data);
//---close the activity---
finish();

So then again in the first activity you write the below code in onActivityResult()

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == request_Code) {
        if (resultCode == RESULT_OK) {
            String returnedResult = data.getData().toString();
            // OR
            // String returnedResult = data.getDataString();
        }
    }
}

EDIT based on your comment: If you want to return three strings, then follow this by making use of key/value pairs with intent instead of using Uri.

Intent data = new Intent();
data.putExtra("streetkey","streetname");
data.putExtra("citykey","cityname");
data.putExtra("homekey","homename");
setResult(RESULT_OK,data);
finish();

Get them in onActivityResult like below:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == request_Code) {
        if (resultCode == RESULT_OK) {
            String street = data.getStringExtra("streetkey");
            String city = data.getStringExtra("citykey");
            String home = data.getStringExtra("homekey");
        }
    }
}

For what it's worth, with iOS7 dropping support for datetime you need to use datetime-local which doesn't accept timezone portion (which makes sense).

Doesn't work (iOS anyway):

 <input type="datetime-local" value="2000-01-01T00:00:00+05:00" />

Works:

<input type="datetime-local" value="2000-01-01T00:00:00" />

PHP for value (windows safe):

strftime('%Y-%m-%dT%H:%M:%S', strtotime($my_datetime_input))

<head runat="server">
<title>Accessing GridView Hidden Column value </title>
<style type="text/css">
  .hiddencol
  {
    display: none;
  }
</style>

<asp:BoundField HeaderText="Email ID" DataField="EmailId" ItemStyle-CssClass="hiddencol" HeaderStyle-CssClass="hiddencol" >
</asp:BoundField>

ArrayList EmailList = new ArrayList();
foreach (GridViewRow itemrow in gvEmployeeDetails.Rows)
{
  EmailList.Add(itemrow.Cells[YourIndex].Text);
}

Just add map:

" ~/.vimrc
inoremap <c-p> <c-r>*

restart vim and when press Crtl+p in insert mode, copied text will be pasted

How about this? Bootstrap 4

<div class="row justify-content-end">
    <div class="col-3">
        The content is positioned as if there was
        "col-9" classed div appending this one.
    </div>
</div>

Try this for stored procedures:

SELECT name, create_date, modify_date
FROM sys.objects
WHERE type = 'P'
AND name = 'myProc'

To avoid reinit(affect performance) of prefix use TextUtils.isEmpty:

            String prefix = "";
            for (String item : list) {
                sb.append(prefix);
                if (TextUtils.isEmpty(prefix))
                    prefix = ",";
                sb.append(item);
            }

It's worth noting that the QuerySet.values_list() method doesn't actually return a list, but an object of type django.db.models.query.ValuesListQuerySet, in order to maintain Django's goal of lazy evaluation, i.e. the DB query required to generate the 'list' isn't actually performed until the object is evaluated.

Somewhat irritatingly, though, this object has a custom __repr__ method which makes it look like a list when printed out, so it's not always obvious that the object isn't really a list.

The exception in the question is caused by the fact that custom objects cannot be serialized in JSON, so you'll have to convert it to a list first, with...

my_list = list(self.get_queryset().values_list('code', flat=True))

...then you can convert it to JSON with...

json_data = json.dumps(my_list)

You'll also have to place the resulting JSON data in an HttpResponse object, which, apparently, should have a Content-Type of application/json, with...

response = HttpResponse(json_data, content_type='application/json')

...which you can then return from your function.

First To get maximum attention at minimum time, you'll want to use a high-level language. probably you'll want to show 3D.

I'd go with Opengl - I'd start by showing a short scene from a 3d computer game, then explaining, that this was done by dividing the big program into smaller parts, and then showing them how a little part may look like. something like lesson 05 on nehe.gamedev.net, or maybe even a more advanced lesson. it's quite impressive, and not too complicated.

Also you may want to check Alice which contains 3d and was designed to teach..

That for changing directory of the XAMPP. So you have to change the Directory as well as ServerRoot "E:/xampp/apache"

DocumentRoot "E:/xampp/htdocs"


<Directory "E:/xampp/htdocs">


ScriptAlias /cgi-bin/ "E:/xampp/cgi-bin/"


<Directory "E:/xampp/cgi-bin">
    AllowOverride All
    Options None
    Require all granted
</Directory>

I also facing same problem for changing My laptop. thanks

For me, I solved it this way:

rm .git/refs/remotes/origin/master
git fetch

After that I get this message from github.

There is no tracking information for the current branch

So next I did to fix this was:

git branch --set-upstream-to=origin/master master
git pull

I could not find a single pattern correct. Please follow below guide for a small and sweet solution.

String regex = "(.)*(\\d)(.)*";      
Pattern pattern = Pattern.compile(regex);
String msg = "What is the square of 10?";
boolean containsNumber = pattern.matcher(msg).matches();

Nope.

While in debug configuration there is a DEBUG defined constant (automatically defined by Visual Studio) while there is no such constant defined for release mode. Check your project settings under build.

Selecting [Define DEBUG constant] under Project -> Build is like including #define DEBUG at the beginning of every file.

If you want to define a RELEASE constant for the release configuration go to:

• Project Properties -> Build
• Select Release Mode
• in the Conditional compilation symbols textbox enter: RELEASE

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

the OOP way to do this in ES5 is to make that variable into a property using the this keyword.

function first(){
    this.nameContent=document.getElementById('full_name').value;
}

function second() {
    y=new first();
    alert(y.nameContent);
}

Use: "%.2f" or variations on that.

See the POSIX spec for an authoritative specification of the printf() format strings. Note that it separates POSIX extras from the core C99 specification. There are some C++ sites which show up in a Google search, but some at least have a dubious reputation, judging from comments seen elsewhere on SO.

Since you're coding in C++, you should probably be avoiding printf() and its relatives.

Actually, the simplest way to do it could be to:

1. record the merge-base between the two branches: MERGE_BASE=$(git merge-base branch-a branch-b)
2. fast-forward or rebase the older branch onto the newer branch

3. rebase the resulting branch onto itself, starting at the merge base from step 1, and manually remove commits that are not desired:

   git rebase ${SAVED_MERGE_BASE} -i
   

   Alternatively, if there are only a few new commits, skip step 1, and simply use

   git rebase HEAD^^^^^^^ -i
   

   in the first step, using enough ^ to move past the merge-base.

You will see something like this in the interactive rebase:

pick 3139276 commit a
pick c1b421d commit b
pick 7204ee5 commit c
pick 6ae9419 commit d
pick 0152077 commit e
pick 2656623 commit f

Then remove lines b (and any others you want)

vimdiff. It's great. All you need is a window three feet wide.

Code Runner Extension will only let you "run" java files.

To truly debug 'Java' files follow the quick one-time setup:

• Install Java Debugger Extension in VS Code and reload.
• open an empty folder/project in VS code.
• create your java file (s).
• create a folder .vscode in the same folder.
• create 2 files inside .vscode folder: tasks.json and launch.json
• copy paste below config in tasks.json:

{
    "version": "2.0.0",
    "type": "shell",
    "presentation": {
        "echo": true,
        "reveal": "always",
        "focus": false,
        "panel": "shared"
    },
    "isBackground": true,
    "tasks": [
        {
            "taskName": "build",
            "args": ["-g", "${file}"],
            "command": "javac"
        }
    ]
}

• copy paste below config in launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Java",
            "type": "java",
            "request": "launch",
            "externalConsole": true,                //user input dosen't work if set it to false :(
            "stopOnEntry": true,
            "preLaunchTask": "build",                 // Runs the task created above before running this configuration
            "jdkPath": "${env:JAVA_HOME}/bin",        // You need to set JAVA_HOME enviroment variable
            "cwd": "${workspaceRoot}",
            "startupClass": "${workspaceRoot}${file}",
            "sourcePath": ["${workspaceRoot}"],   // Indicates where your source (.java) files are
            "classpath": ["${workspaceRoot}"],    // Indicates the location of your .class files
            "options": [],                             // Additional options to pass to the java executable
            "args": []                                // Command line arguments to pass to the startup class
        }

    ],
    "compounds": []
}

You are all set to debug java files, open any java file and press F5 (Debug->Start Debugging).

Tip: *To hide .class files in the side explorer of VS code, open settings of VS code and paste the below config:

"files.exclude": {
        "*.class": true
    }

I had the same problem and tried all possible solution. But finally I came to know from the documentation that ngRoute module is now separated. Have a look to this link

Solution: Add the cdn angular-route.js after angular.min.js script

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular-route.js"></script>

I know it is a bit late of a reply but you can use the below syntax as it worked with me just fine

Camera=(Button)findViewById(R.id.CameraID);
Camera.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent Intent3=new   Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA);
            startActivity(Intent3); 
        }
    });

In some locales like Hebrew, there are leap months dependant upon the year so to avoid errors in such locales you might consider the following solution:

SELECT DATENAME(month, STR(YEAR(GETDATE()), 4) + REPLACE(STR(@month, 2), ' ', '0') + '01')     

This works by exploiting the % properties of the list rather than the increments.

for num in range(1,100):
    if num % 4 == 1 or num % 4 ==2:
        n.append(num)
        continue
    pass

COMMENT FOR SWIFT 3.0 AND SWIFT WARNING

You can remove the warning message in line:

let initCoderMethod = class_getInstanceMethod(self, Selector("initWithCoder:"))

By replacing it with:

let initCoderMethod = class_getInstanceMethod(self, #selector(UIFontDescriptor.init(coder:)))

Make sure you aren't trying to use the same User object more than once while changing the ID. In other words, if you were doing something in a batch type operation:

User user = new User();  // Using the same one over and over, won't work
List<Customer> customers = fetchCustomersFromSomeService();
for(Customer customer : customers) {
 // User user = new User(); <-- This would work, you get a new one each time
 user.setId(customer.getId());
 user.setName(customer.getName());
 saveUserToDB(user);
}

Ideally you would put that in a directive, but you can also just put it in the controller. http://jsfiddle.net/tnq86/15/

  angular.module('App', [])
    .controller('AppCtrl', function ($scope) {

      $scope.model = 0;

      $scope.initSlider = function () {
          $(function () {
            // wait till load event fires so all resources are available
              $scope.$slider = $('#slider').slider({
                  slide: $scope.onSlide
              });
          });

          $scope.onSlide = function (e, ui) {
             $scope.model = ui.value;
             $scope.$digest();
          };
      };

      $scope.initSlider();
  });

The directive approach:

HTML

<div slider></div>

JS

  angular.module('App', [])
    .directive('slider', function (DataModel) {
      return {
         restrict: 'A',
         scope: true,
         controller: function ($scope, $element, $attrs) {
            $scope.onSlide = function (e, ui) {
              $scope.model = ui.value;
              // or set it on the model
              // DataModel.model = ui.value;
              // add to angular digest cycle
              $scope.$digest();
            };
         },
         link: function (scope, el, attrs) {

            var options = {
              slide: scope.onSlide  
            };

            // set up slider on load
            angular.element(document).ready(function () {
              scope.$slider = $(el).slider(options);
            });
         }
      }
  });

I would also recommend checking out Angular Bootstrap's source code: https://github.com/angular-ui/bootstrap/blob/master/src/tooltip/tooltip.js

You can also use a factory to create the directive. This gives you ultimate flexibility to integrate services around it and whatever dependencies you need.

The best solution is a minimal use of java directly in the visualstudio GUI

here it is: On a button go to the "OnClientClick" property (its not into events*) overthere type:

return confirm('are you sure?')

it will put a dialog with cancel ok buttons transparent over current page if cancel is pressed no postback will ocure. However if you want only ok button type:

alert ('i told you so')

The events like onclick work server side they execute your code, while OnClientClick runs in the browser side. the come most close to a basic dialog

It says:

When you save and exit the editor, it will rewind you back to that last commit in that list and drop you on the command line with the following message:

$ git rebase -i HEAD~3
Stopped at 7482e0d... updated the gemspec to hopefully work better
You can amend the commit now, with

It does not mean:

type again git rebase -i HEAD~3

Try to not typing git rebase -i HEAD~3 when exiting the editor, and it should work fine.
(otherwise, in your particular situation, a git rebase -i --abort might be needed to reset everything and allow you to try again)

As Dave Vogt mentions in the comments, git rebase --continue is for going to the next task in the rebasing process, after you've amended the first commit.

Also, Gregg Lind mentions in his answer the reword command of git rebase:

By replacing the command "pick" with the command "edit", you can tell git rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

If you just want to edit the commit message for a commit, replace the command "pick" with the command "reword", since Git1.6.6 (January 2010).

It does the same thing ‘edit’ does during an interactive rebase, except it only lets you edit the commit message without returning control to the shell. This is extremely useful.
Currently if you want to clean up your commit messages you have to:

$ git rebase -i next

Then set all the commits to ‘edit’. Then on each one:

# Change the message in your editor.
$ git commit --amend
$ git rebase --continue

Using ‘reword’ instead of ‘edit’ lets you skip the git-commit and git-rebase calls.

Action Management On Controls

Create below class in base class. Class To get all controls:

public static class ControlExtensions
{
    public static IEnumerable<T> GetAllControlsOfType<T>(this Control parent) where T : Control
    {
        var result = new List<T>();
        foreach (Control control in parent.Controls)
        {
            if (control is T)
            {
                result.Add((T)control);
            }
            if (control.HasControls())
            {
                result.AddRange(control.GetAllControlsOfType<T>());
            }
        }
        return result;
    }
}

From Database: Get All Actions IDs (like divAction1,divAction2 ....) dynamic in DATASET (DTActions) allow on specific User.

In Aspx: in HTML Put Action(button,anchor etc) in div or span and give them id like

<div id="divAction1" visible="false" runat="server" clientidmode="Static">   
                <a id="anchorAction" runat="server">Submit
                        </a>                      
                 </div>

IN CS: Use this function on your page:

private void ShowHideActions()
    {

        var controls = Page.GetAllControlsOfType<HtmlGenericControl>();

        foreach (DataRow dr in DTActions.Rows)
        {          

            foreach (Control cont in controls)
            {

                if (cont.ClientID == "divAction" + dr["ActionID"].ToString())
                {
                    cont.Visible = true;
                }

            }
        }
    }

This worked for me.

RowCounter = Sheets(3).UsedRange.Rows.Count + 1

Sheets(1).Rows(rowNum).EntireRow.Copy
Sheets(3).Activate
Sheets(3).Cells(RowCounter, 1).Select
Sheets(3).Paste
Sheets(1).Activate

First, you do not need android:process=":remote", so please remove it, since all it will do is take up extra RAM for no benefit.

Second, since the <service> element contains an action string, use it:

public void onCreate(Bundle savedInstanceState) {    
      super.onCreate(savedInstanceState);  
      Intent intent=new Intent("com.sample.service.serviceClass");  
      this.startService(intent);
}

Chrome:

console._commandLineAPI.clear();

Safari:

console._inspectorCommandLineAPI.clear();

You can create your own variable, which works in both:

if (typeof console._commandLineAPI !== 'undefined') {
    console.API = console._commandLineAPI;
} else if (typeof console._inspectorCommandLineAPI !== 'undefined') {
    console.API = console._inspectorCommandLineAPI;
} else if (typeof console.clear !== 'undefined') {
    console.API = console;
}

After that, you can simply use console.API.clear().

url prop is deprecated as of Next.js version 6: https://github.com/zeit/next.js/blob/master/errors/url-deprecated.md

To get the query parameters, use getInitialProps:

For stateless components

import Link from 'next/link'
const About = ({query}) => (
  <div>Click <Link href={{ pathname: 'about', query: { name: 'leangchhean' }}}><a>here</a></Link> to read more</div>
)

About.getInitialProps = ({query}) => {
  return {query}
}

export default About;

For regular components

class About extends React.Component {

  static getInitialProps({query}) {
    return {query}
  }

  render() {
    console.log(this.props.query) // The query is available in the props object
    return <div>Click <Link href={{ pathname: 'about', query: { name: 'leangchhean' }}}><a>here</a></Link> to read more</div>

  }
}

The query object will be like: url.com?a=1&b=2&c=3 becomes: {a:1, b:2, c:3}

You can't have async methods with ref or out parameters.

Lucian Wischik explains why this is not possible on this MSDN thread: http://social.msdn.microsoft.com/Forums/en-US/d2f48a52-e35a-4948-844d-828a1a6deb74/why-async-methods-cannot-have-ref-or-out-parameters

As for why async methods don't support out-by-reference parameters? (or ref parameters?) That's a limitation of the CLR. We chose to implement async methods in a similar way to iterator methods -- i.e. through the compiler transforming the method into a state-machine-object. The CLR has no safe way to store the address of an "out parameter" or "reference parameter" as a field of an object. The only way to have supported out-by-reference parameters would be if the async feature were done by a low-level CLR rewrite instead of a compiler-rewrite. We examined that approach, and it had a lot going for it, but it would ultimately have been so costly that it'd never have happened.

A typical workaround for this situation is to have the async method return a Tuple instead. You could re-write your method as such:

public async Task Method1()
{
    var tuple = await GetDataTaskAsync();
    int op = tuple.Item1;
    int result = tuple.Item2;
}

public async Task<Tuple<int, int>> GetDataTaskAsync()
{
    //...
    return new Tuple<int, int>(1, 2);
}

Try this.

$sub_total = 0;

and within your loop now you can use this

$sub_total += ($item['quantity'] * $product['price']);

It should solve your problem.

You can try using JavaScript's Date Object

new Date(year,month).getFullYear()%4==0

This will return true or false.

As Sai said, the shell is the child, so signals are intercepted by it -- best way I've found is to use shell=False and use shlex to split the command line:

if isinstance(command, unicode):
    cmd = command.encode('utf8')
args = shlex.split(cmd)

p = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

Then p.kill() and p.terminate() should work how you expect.

If you are on a *nix machine:

man 3 printf

This will show a manual page, similar to:

0 The value should be zero padded. For d, i, o, u, x, X, a, A, e, E, f, F, g, and G conversions, the converted value is padded on the left with zeros rather than blanks. If the 0 and - flags both appear, the 0 flag is ignored. If a precision is given with a numeric conversion (d, i, o, u, x, and X), the 0 flag is ignored. For other conversions, the behavior is undefined.

Even though the question is for C, this page may be of aid.

You can not directly send an email with a HTML form. You can however send the form to your web server and then generate the email with a server side program written in e.g. PHP.

The other solution is to create a link as you did with the "mailto:". This will open the local email program from the user. And he/she can then send the pre-populated email.

When you decided how you wanted to do it you can ask another (more specific) question on this site. (Or you can search for a solution somewhere on the internet.)

Instead of

host = socket.gethostname() #Get the local machine name
port = 12397 # Reserve a port for your service
s.bind((host,port)) #Bind to the port

you should try

port = 12397 # Reserve a port for your service
s.bind(('', port)) #Bind to the port

so that the listening socket isn't too restricted. Maybe otherwise the listening only occurs on one interface which, in turn, isn't related with the local network.

One example could be that it only listens to 127.0.0.1, which makes connecting from a different host impossible.

If you are willing to use custom table header as table header, try the followings....

Updated for swift 3.0

Step 1

Create UITableViewHeaderFooterView for custom header..

import UIKit

class MapTableHeaderView: UITableViewHeaderFooterView {

    @IBOutlet weak var testView: UIView!

}

Step 2

Add custom header to UITableView

    override func viewDidLoad() {
            super.viewDidLoad()

            tableView.delegate = self
            tableView.dataSource = self

            //register the header view

            let nibName = UINib(nibName: "CustomHeaderView", bundle: nil)
            self.tableView.register(nibName, forHeaderFooterViewReuseIdentifier: "CustomHeaderView")


    }

    extension BranchViewController : UITableViewDelegate{

    }

    extension BranchViewController : UITableViewDataSource{

        func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
            return 200
        }

        func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
            let headerView = self.tableView.dequeueReusableHeaderFooterView(withIdentifier: "CustomHeaderView" ) as! MapTableHeaderView

            return headerView
        }

        func tableView(_ tableView: UITableView, numberOfRowsInSection section: 

    Int) -> Int {
            // retuen no of rows in sections
        }

        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
            // retuen your custom cells    
        }

        func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        }

        func numberOfSections(in tableView: UITableView) -> Int {
            // retuen no of sections
        }

        func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
            // retuen height of row
        }


    }

Try pressing Ctrl + Alt + Space (which toggles between suggestion and standard completion modes)

You have an error in you script tag construction, this:

<script language="JavaScript" type="text/javascript" script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

Should look like this:

<script language="JavaScript" type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

You have a 'script' word lost in the middle of your script tag. Also you should remove the http:// to let the browser decide whether to use HTTP or HTTPS.

UPDATE

But your main error is that you are including jQuery UI (ONLY) you must include jQuery first! jQuery UI and jQuery are used together, not in separate. jQuery UI depends on jQuery. You should put this line before jQuery UI:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>

You can customize the standard Linkedin button like this, after the page load:

$(".IN-widget span:first-of-type").css({
                'border': '2px solid #DCDCDC',
                '-webkit-border-radius': '3px',
                '-moz-border-radius': '3px',
                'border-radius': '3px'
                });

Depending on the usecase it makes a difference whether you use javascript (element.value = x) or jQuery $(element).val(x);

When x is undefined jQuery results in an empty String whereas javascript results in "undefined" as a String.

Java 8 has a new concept called “Effectively final” variable. It means that a non-final local variable whose value never changes after initialization is called “Effectively Final”.

This concept was introduced because prior to Java 8, we could not use a non-final local variable in an anonymous class. If you wanna have access to a local variable in anonymous class, you have to make it final.

When lambda was introduced, this restriction was eased. Hence to the need to make local variable final if it’s not changed once it is initialized as lambda in itself is nothing but an anonymous class.

Java 8 realized the pain of declaring local variable final every time a developer used lambda, introduced this concept, and made it unnecessary to make local variables final. So if you see the rule for anonymous classes has not changed, it’s just you don’t have to write the final keyword every time when using lambdas.

I found a good explanation here

I needed this for something as simple as redirecting all http traffic from the default apache home page on my server to one served over https.

Since I'm still quite green when it comes to configuring apache, I prefer to avoid using mod_rewrite directly and instead went for something simpler like this:

<VirtualHost *:80>
  <Location "/">
     Redirect permanent "https://%{HTTP_HOST}%{REQUEST_URI}"
  </Location>
</VirtualHost>

<VirtualHost *:443>
  DocumentRoot "/var/www/html"
  SSLEngine on
  ...
</VirtualHost>

I like this because it allowed me to use apache variables and that way I didn't have to specify the actual host name since it's just an IP address without an associated domain name.

Python language reference:

In order to avoid infinite recursion in this method, its implementation should always call the base class method with the same name to access any attributes it needs, for example, object.__getattribute__(self, name).

Meaning:

def __getattribute__(self,name):
    ...
        return self.__dict__[name]

You're calling for an attribute called __dict__. Because it's an attribute, __getattribute__ gets called in search for __dict__ which calls __getattribute__ which calls ... yada yada yada

return  object.__getattribute__(self, name)

Using the base classes __getattribute__ helps finding the real attribute.

.htpasswd entries are HASHES. They are not encrypted passwords. Hashes are designed not to be decryptable. Hence there is no way (unless you bruteforce for a loooong time) to get the password from the .htpasswd file.

What you need to do is apply the same hash algorithm to the password provided to you and compare it to the hash in the .htpasswd file. If the user and hash are the same then you're a go.

For a fully transparent background use:

background: transparent;

Otherwise for a semi-transparent color fill use:

background: rgba(255,255,255,0.5); // or hsla(0, 0%, 100%, 0.5)

where the values are:

background: rgba(red,green,blue,opacity); // or hsla(hue, saturation, lightness, opacity)

You can also use rgba values for gradient backgrounds.

To get transparency on an image background simply reduce the opacity of the image in an image editor of you choice beforehand.

If you can't use a public/private keys, you can use expect:

#!/usr/bin/expect
spawn rsync SRC DEST
expect "password:"
send "PASS\n"
expect eof
if [catch wait] {
    puts "rsync failed"
    exit 1
}
exit 0

You will need to replace SRC and DEST with your normal rsync source and destination parameters, and replace PASS with your password. Just make sure this file is stored securely!
