Please keep in mind that my answer has aged a lot.
There are other more technically sophisticated answers below, e.g.:
so don't let the fact that this is the currently accepted answer give you the impression that this is still the best one.
You can also now also download google's entire font set via on github at their google/font repository. They also provide a ~420MB zip snapshot of their fonts.
You first download your font selection as a zipped package, providing you with a bunch of true type fonts. Copy them somewhere public, somewhere you can link to from your css.
On the google webfont download page, you'll find a include link like so:
http://fonts.googleapis.com/css?family=Cantarell:400,700,400italic,700italic|Candal
It links to a CSS defining the fonts via a bunch of @font-face
defintions.
Open it in a browser to copy and paste them into your own CSS and modify the urls to include the right font file and format types.
So this:
@font-face {
font-family: 'Cantarell';
font-style: normal;
font-weight: 700;
src: local('Cantarell Bold'), local('Cantarell-Bold'), url(http://themes.googleusercontent.com/static/fonts/cantarell/v3/Yir4ZDsCn4g1kWopdg-ehHhCUOGz7vYGh680lGh-uXM.woff) format('woff');
}
becomes this:
/* Your local CSS File */
@font-face {
font-family: 'Cantarell';
font-style: normal;
font-weight: 700;
src: local('Cantarell Bold'), local('Cantarell-Bold'), url(../font/Cantarell-Bold.ttf) format('truetype');
}
As you can see, a downside of hosting the fonts on your own system this way is, that you restrict yourself to the true type format, whilst the google webfont service determines by the accessing device which formats will be transmitted.
Furthermore, I had to add a .htaccess
file to my the directory holding the fonts containing mime types to avoid errors from popping up in Chrome Dev Tools.
For this solution, only true type is needed, but defining more does not hurt when you want to include different fonts as well, like font-awesome
.
#.htaccess
AddType application/vnd.ms-fontobject .eot
AddType font/ttf .ttf
AddType font/otf .otf
AddType application/x-font-woff .woff
Please put this code in head section
<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>
and use font-family: 'Lato', sans-serif;
in your css. For example:
h1 {
font-family: 'Lato', sans-serif;
font-weight: 400;
}
Or you can use manually also
Generate .ttf
font from fontSquiral
and can try this option
@font-face {
font-family: "Lato";
src: url('698242188-Lato-Bla.eot');
src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
url('698242188-Lato-Bla.woff') format('woff'),
url('698242188-Lato-Bla.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
Called like this
body {
font-family: 'Lato', sans-serif;
}
In some cases your font resource maybe somewhere in your project directory. So you can load it like this using SCSS
$list: (
"Black",
"BlackItalic",
"Bold",
"BoldItalic",
"Italic",
"Light",
"LightItalic",
"Medium",
"MediumItalic",
"Regular",
"Thin",
"ThinItalic"
);
@mixin setRobotoFonts {
@each $var in $list {
@font-face {
font-family: "Roboto-#{$var}";
src: url("../fonts/Roboto-#{$var}.ttf") format("ttf");
}
}
}
@include setRobotoFonts();
Simply declare your variable to final
I managed to do this with a pretty simple bit of CSS. This does require that the error messages be siblings of the input they relate to, and that they have a class of error
.
:focus ~ .error {
display:none;
}
After meeting those two requirements, this will hide any error message related to a focused input field, something that I think angularjs should be doing anyway. Seems like an oversight.
Not really an answer to your question but validating url's is really a serious p.i.t.a You're probably just better off validating the domainname and leave query part of the url be. That is my experience. You could also resort to pinging the url and seeing if it results in a valid response but that might be too much for such a simple task.
Regular expressions to detect url's are abundant, google it :)
You may want to use statement_timestamp(). This give the timestamp when the statement was executed. Whereas NOW()
and CURRENT_TIMESTAMP
give the timestamp when the transaction started.

I was experiencing this same error, and spent forever adding the suggested startup statements to various config files in my solution, attempting to isolate the framework mismatch. Nothing worked. I also added startup information to my XML schemas. That didn't help either. Looking at the actual file that was causing the problem (which would only say it was "moved or deleted") revealed it was actually the License Compiler (LC).
Deleting the offending licenses.licx file seems to have fixed the problem.
There is a super() in python also.
Example for how a super class method is called from a sub class method
class Dog(object):
name = ''
moves = []
def __init__(self, name):
self.name = name
def moves_setup(self,x):
self.moves.append('walk')
self.moves.append('run')
self.moves.append(x)
def get_moves(self):
return self.moves
class Superdog(Dog):
#Let's try to append new fly ability to our Superdog
def moves_setup(self):
#Set default moves by calling method of parent class
super().moves_setup("hello world")
self.moves.append('fly')
dog = Superdog('Freddy')
print (dog.name)
dog.moves_setup()
print (dog.get_moves())
This example is similar to the one explained above.However there is one difference that super doesn't have any arguments passed to it.This above code is executable in python 3.4 version.

Steps I followed
1) Execute the command adb nodaemon server
in command prompt
Output at command prompt will be: The following error occurred cannot bind 'tcp:5037'
The original ADB server port binding failed
2) Enter the following command query which using port 5037
netstat -ano | findstr "5037"
The following information will be prompted on command prompt: TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 9288
3) View the task manager, close all adb.exe
4) Restart eclipse or other IDE
The above steps worked for me.
Changing the target framework from .NET Framework 4 Client Profile to .NET Framework 4 fixed this problem for me.
So in your example: set the target framework on MyWebProject1 to .NET Framework 4
TL;DR Make a copy or alias of your python.exe with name python2.7.exe
My python 2.7 was installed as
D:\app\Python27\python.exe
I always got this error no matter how I set (and verified) PYTHON env variable:
gyp ERR! stack Error: Can't find Python executable "python2.7", you can set the PYTHON env variable. gyp ERR! stack at failNoPython (C:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\lib\configure.js:103:14)
The reason for this was that in node-gyp's configure.js the python executable was resolved like:
var python = gyp.opts.python || process.env.PYTHON || 'python'
And it turned out that gyp.opts.python had value 'python2.7' thus overriding process.env.PYTHON.
I resolved this by creating an alias for python.exe executable with name node-gyp was looking for:
D:\app\Python27>mklink python2.7.exe python.exe
You need admin rights for this operation.
I had a similar problem to the OP when upgrading php5 from an older version, to 5.5.9, which is the version installed with Mint 17.
I'm running a LAMP setup on a machine on my local network, which I use to preview changes to websites before I upload those changes to the actual live server. So I maintain a perfect local mirror of the actual site.
After the upgrade, files which run and display perfectly on the actual site would not display, or would only display html on the local machine. PHP was not parsed. The phpinfo() command worked, so I knew php was otherwise working. The log generated no errors. Viewing the page source showed me the actual php code.
I had constructed a test.php page that contained the following code:
<?php
phpinfo();
?>
This worked. Then I discovered when I changed <?php
to <?
the command no longer worked. All my php sites use <?
instead of <?php
which might not be ideal, but it's the reality. I fixed the problem by going to /etc/php5/apache2 , searching for "short_open_tag" and changing the value from Off to On.
Have you tried adding the various HTTP Header options for no-cache to the iframe page?
Just a note. In case you want train, test, AND validation sets, you can do this:
from sklearn.cross_validation import train_test_split
X = get_my_X()
y = get_my_y()
x_train, x_test, y_train, y_test = train_test_split(X, y, test_size=0.3)
x_test, x_val, y_test, y_val = train_test_split(x_test, y_test, test_size=0.5)
These parameters will give 70 % to training, and 15 % each to test and val sets. Hope this helps.
You can fprintf to stderr, which is unbuffered, instead. Or you can flush stdout when you want to. Or you can set stdout to unbuffered.
If you're using a JFrame, try this
JFrame frame = new JFrame();
//...
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
synchronized should only be used when you want your class to be Thread safe. In fact most of the classes should not use synchronized anyways. synchronized method would only provide a lock on this object and only for the duration of its execution. if you really wanna to make your classes thread safe, you should consider making your variables volatile or synchronize the access.
one of the issues of using synchronized method is that all of the members of the class would use the same lock which will make your program slower. In your case synchronized method and block would execute no different. what I'd would recommend is to use a dedicated lock and use a synchronized block something like this.
public class AClass {
private int x;
private final Object lock = new Object(); //it must be final!
public void setX() {
synchronized(lock) {
x++;
}
}
}
Though @Simba had a good answer at the time, a lot has changed in the conda env since 4.6. Conda activate (env-name)
overthrew source activate (env-name)
for good but not without it own challenges. conda activate
oftentimes forces your environment to base and makes you see something like this:
and throwing loads of error back at you. This can also be because auto_activate_base
is set to True.
You can check this by using the following command
conda config --set auto_activate_base False
source ~/.bashrc
And to reactivate use this
conda config --set auto_activate_base True
source ~/.bashrc

"Big O notation" is a way to express the speed of algorithms. n
is the amount of data the algorithm is working with. O(1)
means that, no matter how much data, it will execute in constant time. O(n)
means that it is proportional to the amount of data.
For opera just add this in header
<link rel='stylesheet' media='handheld' href='body.css' />
This makes opera use most of your customised css.

I tried this in Chrome, Firefox and IE. It works only in Firefox and IE, it uses the default printer (with default print settings) and only works when I render a PDF (I use Foxit Reader with Safe Reading Mode disabled). Chrome shows the print dialog, also the other browsers when I render an HTML page.
I believe the problem with all the existing ideas is that they are probably unique, but not definitely unique (as pointed out in Dariusz Walczak's reply to loletech). I have a solution that actually is unique. It requires that your script have some sort of memory. For me this is a SQL database. You could also simply write to a file somewhere. There are two implementations:
First method: have TWO fields rather than 1 that provide uniqueness. The first field is an ID number that is not random but is unique (The first ID is 1, the second 2...). If you are using SQL, just define the ID field with the AUTO_INCREMENT property. The second field is not unique but is random. This can be generated with any of the other techniques people have already mentioned. Scott's idea was good, but md5 is convenient and probably good enough for most purposes:
$random_token = md5($_SERVER['HTTP_USER_AGENT'] . time());
Second method: Basically the same idea, but initially pick a maximum number of strings that will ever be generated. This could just be a really big number like a trillion. Then do the same thing, generate an ID, but zero pad it so that all IDs are the same number of digits. Then just concatenate the ID with the random string. It will be random enough for most purposes, but the ID section will ensure that it is also unique.
Would appreciate any thoughts on the situation with 3 data sets. Say a logistic regression model is fitted yielding the following accuracy (Gini): Train: 70%; Test 58% and Out-of-time validation: 66%.
Actually all the possible combinations of predictors bring the same results with quite a huge drop between train and test data sets. The sample size is around 8k divided into train and test 70/30. OOT sample contains a few thousands of cases. Regularization, ensembles didn't help in solving this.
I doubt whether this is something I should concern if OOT performance is acceptable and close to train sample performance?
Try setting a Windows System Environment variable called _JAVA_OPTIONS
with the heap size you want. Java should be able to find it and act accordingly.
My few cents to previous excellent replies. the site www.sqlite.org works on a sqlite database. Here is the link when the author (Richard Hipp) replies to a similar question.
#!/usr/bin/env python
import sys
import yaml
def main(argv):
with open(argv[0]) as stream:
try:
#print(yaml.load(stream))
return 0
except yaml.YAMLError as exc:
print(exc)
return 1
if __name__ == "__main__":
sys.exit(main(sys.argv[1:]))
You can cast null
to any reference type without getting any exception.
The println
method does not throw null pointer because it first checks whether the object is null or not. If null then it simply prints the string "null"
. Otherwise it will call the toString
method of that object.
Adding more details: Internally print methods call String.valueOf(object)
method on the input object. And in valueOf
method, this check helps to avoid null pointer exception:
return (obj == null) ? "null" : obj.toString();
For rest of your confusion, calling any method on a null object should throw a null pointer exception, if not a special case.
you should use while (fileReader.hasNextLine())
Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:
<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
<asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>
If you want to add it at a different index, maybe the last then try:
ListItem lst = new ListItem ( "Add New" , "0" );
DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);
The Output Control functions allow you to control when output is sent from the script. This can be useful in several different situations, especially if you need to send headers to the browser after your script has began outputting data. The Output Control functions do not affect headers sent using header() or setcookie(), only functions such as echo() and data between blocks of PHP code.

Solution for busybox, macOS bash, and non-bash shells
The accepted answer is certainly the best choice for bash. I'm working in a Busybox environment without access to bash, and it does not understand the exec > >(tee log.txt)
syntax. It also does not do exec >$PIPE
properly, trying to create an ordinary file with the same name as the named pipe, which fails and hangs.
Hopefully this would be useful to someone else who doesn't have bash.
Also, for anyone using a named pipe, it is safe to rm $PIPE
, because that unlinks the pipe from the VFS, but the processes that use it still maintain a reference count on it until they are finished.
Note the use of $* is not necessarily safe.
#!/bin/sh
if [ "$SELF_LOGGING" != "1" ]
then
# The parent process will enter this branch and set up logging
# Create a named piped for logging the child's output
PIPE=tmp.fifo
mkfifo $PIPE
# Launch the child process with stdout redirected to the named pipe
SELF_LOGGING=1 sh $0 $* >$PIPE &
# Save PID of child process
PID=$!
# Launch tee in a separate process
tee logfile <$PIPE &
# Unlink $PIPE because the parent process no longer needs it
rm $PIPE
# Wait for child process, which is running the rest of this script
wait $PID
# Return the error code from the child process
exit $?
fi
# The rest of the script goes here
Now I see what you are doing. You cannot send output to the screen then change the headers. If you are trying to create an XML file of map marker and download them to display, they should be in separate files.
Take this
<?php
require("database.php");
function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','<',$htmlStr);
$xmlStr=str_replace('>','>',$xmlStr);
$xmlStr=str_replace('"','"',$xmlStr);
$xmlStr=str_replace("'",''',$xmlStr);
$xmlStr=str_replace("&",'&',$xmlStr);
return $xmlStr;
}
// Opens a connection to a MySQL server
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
die ('Can\'t use db : ' . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
die('Invalid query: ' . mysql_error());
}
header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
// ADD TO XML DOCUMENT NODE
echo '<marker ';
echo 'name="' . parseToXML($row['name']) . '" ';
echo 'address="' . parseToXML($row['address']) . '" ';
echo 'lat="' . $row['lat'] . '" ';
echo 'lng="' . $row['lng'] . '" ';
echo 'type="' . $row['type'] . '" ';
echo '/>';
}
// End XML file
echo '</markers>';
?>
and place it in phpsqlajax_genxml.php
so your javascript can download the XML file. You are trying to do too many things in the same file.
You've mentioned that they each have their own machines, but if they need to log onto a co-workers machine, and then use the file, saving it through "C:\Users\Public\Desktop\" will make it available to different usernames.
Public Sub SaveToDesktop()
ThisWorkbook.SaveAs Filename:="C:\Users\Public\Desktop\" & ThisWorkbook.Name & "_copy", _
FileFormat:=xlOpenXMLWorkbookMacroEnabled
End Sub
I'm not sure whether this would be a requirement, but may help!

Faced with this same problem, I discovered if you have committed and/or pushed to remote since your successful cherry-pick, and you want to remove it, you can find the cherry-pick's SHA by running:
git log --graph --decorate --oneline
Then, (after using :wq
to exit the log) you can remove the cherry-pick using
git rebase -p --onto YOUR_SHA_HERE^ YOUR_SHA_HERE
where YOUR_SHA_HERE
equals the cherry-picked commit's 40- or abbreviated 7-character SHA.
At first, you won't be able to push your changes because your remote repo and your local repo will have different commit histories. You can force your local commits to replace what's on your remote by using
git push --force origin YOUR_REPO_NAME
(I adapted this solution from Seth Robertson: See "Removing an entire commit.")
Try to give the full path to your csv file

The python process is looking for file in the directory it is running from.
If you want them on separate lines do what Balon said. If you want them on the same lines, do:
<td>
<div style="float:left;width:50%;">this is left</div>
<div style="float:right;width:50%;">this is right</div>
</td>
Here in this case,
we are having 3 parameter's in the Method namely ModelandView.
According to this question, the first parameter is easily understood. It represents the View which will be displayed to the client.
The other two parameters are just like The Pointer and The Holder
Hence you can sum it up like this
ModelAndView(View, Pointer, Holder);
The Pointer just points the information in the The Holder
When the Controller binds the View with this information, then in the said process, you can use The Pointer in the JSP page to access the information stored in The Holder to display that respected information to the client.
Here is the visual depiction of the respected process.
return new ModelAndView("welcomePage", "WelcomeMessage", message);
If you're using Angular's ng-repeat to populate the table hackel's jquery snippet will not work by placing it in the document load event. You'll need to run the snippet after angular has finished rendering the table.
To trigger an event after ng-repeat has rendered try this directive:
var app = angular.module('myapp', [])
.directive('onFinishRender', function ($timeout) {
return {
restrict: 'A',
link: function (scope, element, attr) {
if (scope.$last === true) {
$timeout(function () {
scope.$emit('ngRepeatFinished');
});
}
}
}
});
Complete example in angular: http://jsfiddle.net/ADukg/6880/
I got the directive from here: Use AngularJS just for routing purposes

If you are using an SQL query to populate your DataGrid you can do this :
Datagrid fill
Private Sub UserControl_Loaded(sender As Object, e As RoutedEventArgs)
Dim cmd As SqlCommand
Dim da As SqlDataAdapter
Dim dt As DataTable
cmd = New SqlCommand With {
.CommandText = "SELECT * FROM temp_rech_dossier_route",
.Connection = connSQLServer
}
da = New SqlDataAdapter(cmd)
dt = New DataTable("RECH")
da.Fill(dt)
DataGridRech.ItemsSource = dt.DefaultView
End Sub
Value diplay
Private Sub DataGridRech_SelectionChanged(sender As Object, e As SelectionChangedEventArgs) Handles DataGridRech.SelectionChanged
Dim val As DataRowView
val = CType(DataGridRech.SelectedItem, DataRowView)
Console.WriteLine(val.Row.Item("num_dos"))
End Sub
I know it's in VB.Net but it can be translated into C#. I put this solution here, it might be useful for someone.
try this:
string.Format("{0:HH:mm:ss tt}", DateTime.Now);

Personally, I quite like the C++2011 approach because it neither requires you to use sizeof()
nor to remember adjusting the array bounds if you ever change the array bounds (and you can define the relevant function in C++2003 if you want, too):
#include <iterator>
#include <vector>
int x[] = { 1, 2, 3, 4, 5 };
std::vector<int> v(std::begin(x), std::end(x));
Obviously, with C++2011 you might want to use initializer lists anyway:
std::vector<int> v({ 1, 2, 3, 4, 5 });
We can generate tuples from a list comprehension. The following one adds two numbers sequentially into a tuple and gives a list from numbers 0-9.
>>> print k
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99]
>>> r= [tuple(k[i:i+2]) for i in xrange(10) if not i%2]
>>> print r
[(0, 1), (2, 3), (4, 5), (6, 7), (8, 9)]
If you want to add an interval before executing the cron the next time you can add a sleep
for i in
{1..100}
; do echo $i && curl "http://URL" >> /tmp/output.log && sleep 120; done
(Because an ASCII picture is worth a thousand characters.)
An arrow may be a helpful mnemonic, especially since that's almost exactly how it looks in Emacs' dired.
And big picture so you don't get it confused with the Windows' version
Linux:
ln -s target <- linkName
Windows:
mklink linkName -> target
You could also look at these as
ln -s "to-here" <- "from-here"
mklink "from-here" -> "to-here"
The from-here
should not exist yet, it is to be created, while the to-here
should already exist (IIRC).
(I always get mixed up on whether various commands and arguments should involve a pre-existing location, or one to be made.)
EDIT: It's still sinking in slowly for me; I have another way I've written in my notes.
ln -s (target exists) (link is made)
mklink (link is made) (target exists)
From iTunes 12.7 apple removes App Store, So we unable to for find App option
We have another way to install iOS app using iTunes 12.7 as below
1)drag and drop your .app file to iTunes.
2)It will create .ipa file, you can find that at ~/Music/iTunes/iTunes Media/Mobile Applications/
3)connect the device you want to install that app.
4)drag .ipa file from finder to iTunes on my Device section as shown in below section.
Dim nme As String = My.Computer.FileSystem.GetFileInfo(pathFicheiro).Name
Dim dirc As String = My.Computer.FileSystem.GetFileInfo(nomeFicheiro).Directory
It's simple, whenever you see
x->y
know it is the same as
(*x).y
You can use:
File.WriteAllBytes("Foo.txt", arrBytes); // Requires System.IO
If you have an enumerable and not an array, you can use:
File.WriteAllBytes("Foo.txt", arrBytes.ToArray()); // Requires System.Linq
I had the same issue and I even tried to remove the project and add it again. What did the trick was to remove the .settings
directory.
you must mention values as:
Decimal dec = 12M/6;
Double dbl = 11D/6;
float fl = 15F/6;
and check the results.
Float - 4
Double - 8
Decimal - 12
I tried most of the stuff described here. I was using VWD and the default web.config file contained:
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
I changed mode="RemoteOnly" to mode="Off". Still no joy. I then used IIS manager, properties, ASP.Net Tab, Edit configuration, then chose the CustomeErrors tab. This still showed RemoteOnly. I changed this to Off and finally I could see the detailed error messages.
When I inspected the web.config I saw that there were two CustomErrors nodes in the system.web; and I have just noticed that the second entry (the one I was changing was inside a comment). So try not to use notepad to inspect web.config on a remote server.
However, if you use the IIS edit configuration stuff it will complain about errors in the web.config. Then you can rule out all of the answers that say "is there an XML syntax error in your web.config"
Its very simple actually. Try this:
str1="a b c d"
splitStr1 = str1.split()
print splitStr1
Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like
INSERT INTO HISTORICAL_CAR_STATS (
HISTORICAL_CAR_STATS_ID,
YEAR,
MONTH,
MAKE,
MODEL,
REGION,
AVG_MSRP,
CNT)
SELECT MY_SEQ.nextval,
year,
month,
make,
model,
region,
avg_msrp,
cnt
FROM (SELECT '2010' year,
'12' month,
'ALL' make,
'ALL' model,
REGION,
sum(AVG_MSRP*COUNT)/sum(COUNT) avg_msrp,
sum(cnt) cnt
FROM HISTORICAL_CAR_STATS
WHERE YEAR = '2010'
AND MONTH = '12'
AND MAKE != 'ALL'
GROUP BY REGION)
I had to fix this problem with pulling from the remote repo and deal with the merge conflicts that arose, commit and then push. But I feel like there is a better way.
For me I do this to find,
let url = URL(string: urlString)
URLSession.shared.dataTask(with: url!) { (data, response, error) in ...}
Can't use
"let url = NSURL(string: urlString)
For <input type="datetime" value="" ...
A string representing a global date and time.
Value: A valid date-time as defined in [RFC 3339], with these additional qualifications:
•the literal letters T and Z in the date/time syntax must always be uppercase
•the date-fullyear production is instead defined as four or more digits representing a number greater than 0
Examples:
1990-12-31T23:59:60Z
1996-12-19T16:39:57-08:00
http://www.w3.org/TR/html-markup/input.datetime.html#input.datetime.attrs.value
Update:
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The HTML was a control for entering a date and time (hour, minute, second, and fraction of a second) as well as a timezone. This feature has been removed from WHATWG HTML, and is no longer supported in browsers.
Instead, browsers are implementing (and developers are encouraged to use) the datetime-local input type.
Why is HTML5 input type datetime removed from browsers already supporting it?

Using Integer.toHexString(...)
is a good answer. But personally prefer to use String.format(...)
.
Try this sample as a test.
byte[] values = new byte[64];
Arrays.fill(values, (byte)8); //Fills array with 8 just for test
String valuesStr = "";
for(int i = 0; i < values.length; i++)
valuesStr += String.format("0x%02x", values[i] & 0xff) + " ";
valuesStr.trim();
I have created a SQL Server User Defined Function to calculate someone's age, given their birthdate. This is useful when you need it as part of a query:
using System;
using System.Data;
using System.Data.Sql;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
public partial class UserDefinedFunctions
{
[SqlFunction(DataAccess = DataAccessKind.Read)]
public static SqlInt32 CalculateAge(string strBirthDate)
{
DateTime dtBirthDate = new DateTime();
dtBirthDate = Convert.ToDateTime(strBirthDate);
DateTime dtToday = DateTime.Now;
// get the difference in years
int years = dtToday.Year - dtBirthDate.Year;
// subtract another year if we're before the
// birth day in the current year
if (dtToday.Month < dtBirthDate.Month || (dtToday.Month == dtBirthDate.Month && dtToday.Day < dtBirthDate.Day))
years=years-1;
int intCustomerAge = years;
return intCustomerAge;
}
};
Nope - but you could use a template column:
<script runat="server">
TResult Eval<T, TResult>(string field, Func<T, TResult> converter) {
object o = DataBinder.Eval(Container.DataItem, field);
if (converter == null) {
return (TResult)o;
}
return converter((T)o);
}
</script>
<asp:TemplateField>
<ItemTemplate>
<%# Eval<bool, string>("Active", b => b ? "Yes" : "No") %>
</ItemTemplate>
</asp:TemplateField>
Using plain javascript:
element.parentNode
In jQuery:
element.parent()
I was experiencing the same issue.. I already had 4 controllers going and working just fine but when I added this one it returned "The requested resource does not support HTTP method 'GET'". I tried everything here and in a couple other relevant articles but was indifferent to the solution since, as Dan B. mentioned in response to the answer, I already had others working fine.
I walked away for a while, came back, and immediately realized that when I added the Controller it was nested under the "Controller" class and not "ApiController" class that my other Controllers were under. I'm assuming I chose the wrong scaffolding option to build the .cs file in Visual Studio. So I included the System.Web.Http namespace, changed the parent class, and everything works without the additional attributes or routing.
Try with:
@Scheduled(cron = "0 1 1 * * ?")
Below you can find the example patterns from the spring forum:
* "0 0 * * * *" = the top of every hour of every day.
* "*/10 * * * * *" = every ten seconds.
* "0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
* "0 0 8,10 * * *" = 8 and 10 o'clock of every day.
* "0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30 and 10 o'clock every day.
* "0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays
* "0 0 0 25 12 ?" = every Christmas Day at midnight
Cron expression is represented by six fields:
second, minute, hour, day of month, month, day(s) of week
(*)
means match any
*/X
means "every X"
?
("no specific value") - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but I don't care what day of the week that happens to be, I would put "10" in the day-of-month field and "?" in the day-of-week field.
PS: In order to make it work, remember to enable it in your application context: https://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/scheduling.html#scheduling-annotation-support
I had the exact same issue. My problem stemmed from beginning app development under a free developer account and then switching app development to subscription (paid) developer account. The original free developer account already had registered the bundle identifier that your paid developer account is trying to use.
You can verify that this is the problem by going to Xcode -> Preferences -> Accounts -> and then look under Team. If you see both your free (personal) team and your new paid team both listed then your probably having the same issue I had. The two teams are interfering with each other and you need to remove the free (personal) team now that you want to use your paid developer account.
Unfortunately, the only solution is to call apple development support at 1-800-633-2152 (US & Canada) and have them deactivate the free (personal) account from the app so that your paid developer account can register the bundle identifier.
In mongodb _id field is reserved for primary key. Mongodb use an internal ObjectId value if you don't define it in your object and also create an index to ensure performance.
But you can put your own unique value for _id and Mongodb will use it instead of making one for you. And even if you want to use multiple field as primary key you can use an object:
{ _id : { a : 1, b: 1} }
Just be careful when creating these ids that the order of keys (a and b in the example) matters, if you swap them around, it is considered a different object.
A dplyr
solution to get the count could be:
summarise_all(df, ~sum(is.na(.)))
Or to get a percentage:
summarise_all(df, ~(sum(is_missing(.) / nrow(df))))
Maybe also worth noting that missing data can be ugly, inconsistent, and not always coded as NA
depending on the source or how it's handled when imported. The following function could be tweaked depending on your data and what you want to consider missing:
is_missing <- function(x){
missing_strs <- c('', 'null', 'na', 'nan', 'inf', '-inf', '-9', 'unknown', 'missing')
ifelse((is.na(x) | is.nan(x) | is.infinite(x)), TRUE,
ifelse(trimws(tolower(x)) %in% missing_strs, TRUE, FALSE))
}
# sample ugly data
df <- data.frame(a = c(NA, '1', ' ', 'missing'),
b = c(0, 2, NaN, 4),
c = c('NA', 'b', '-9', 'null'),
d = 1:4,
e = c(1, Inf, -Inf, 0))
# counts:
> summarise_all(df, ~sum(is_missing(.)))
a b c d e
1 3 1 3 0 2
# percentage:
> summarise_all(df, ~(sum(is_missing(.) / nrow(df))))
a b c d e
1 0.75 0.25 0.75 0 0.5
You can use the standard MaterialCard
included in the official Material Components library.
Use in your layout:
<com.google.android.material.card.MaterialCardView
style="@style/MyCardView"
...>
In your style use the shapeAppearanceOverlay
attribute to customize the shape (the default corner radius is 4dp
)
<style name="MyCardView" parent="@style/Widget.MaterialComponents.CardView">
<item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.MaterialCardView.Cut</item>
</style>
<style name="ShapeAppearanceOverlay.MaterialCardView.Cut" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSizeTopRight">8dp</item>
<item name="cornerSizeTopLeft">8dp</item>
<item name="cornerSizeBottomRight">0dp</item>
<item name="cornerSizeBottomLeft">0dp</item>
</style>
You can also use:
<com.google.android.material.card.MaterialCardView
app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.MaterialCardView.Cut"
...>
It is the result:
You have two options for this:
1.) make changes in the settings.xml add this in first tag
<localRepository>C:/Users/admin/.m2/repository</localRepository>
2.) use the -o tag for offline command.
mvn -o clean install -DskipTests=true
mvn -o jetty:run
Here is simple sample from android developer.
Basically, you can write a file in the internal storage like this :
String FILENAME = "hello_file";
String string = "hello world!";
FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();
you can also use this to read all the lines in the file one by one then print i
#include <iostream>
#include <fstream>
using namespace std;
bool check_file_is_empty ( ifstream& file){
return file.peek() == EOF ;
}
int main (){
string text[256];
int lineno ;
ifstream file("text.txt");
int num = 0;
while (!check_file_is_empty(file))
{
getline(file , text[num]);
num++;
}
for (int i = 0; i < num ; i++)
{
cout << "\nthis is the text in " << "line " << i+1 << " :: " << text[i] << endl ;
}
system("pause");
return 0;
}
hope this could help you :)
I created a ~/.wgetrc
file with the following content (obtained from askapache.com but with a newer user agent, because otherwise it didn’t work always):
header = Accept-Language: en-us,en;q=0.5
header = Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
header = Connection: keep-alive
user_agent = Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:40.0) Gecko/20100101 Firefox/40.0
referer = /
robots = off
Now I’m able to download from most (all?) file-sharing (streaming video) sites.
why dont you add a "source" column to each of the queries with a static value like
select 'source 1' as Source, column1, column2...
from table1
UNION ALL
select 'source 2' as Source, column1, column2...
from table2
If you are writing code for Node, using Node modules as described by Ivan is without a doubt the way to go.
However, if you need to load JavaScript that has already been written and isn't aware of node, the vm
module is the way to go (and definitely preferable to eval
).
For example, here is my execfile
module, which evaluates the script at path
in either context
or the global context:
var vm = require("vm");
var fs = require("fs");
module.exports = function(path, context) {
var data = fs.readFileSync(path);
vm.runInNewContext(data, context, path);
}
Also note: modules loaded with require(…)
don't have access to the global context.
make a class for that button lets say :
`<input type="button" value="+" class="b1" onclick="addRow()">`
your js should look like this :
$(document).ready(function(){
$('.b1').click(function(){
$('div').append('<input type="text"..etc ');
});
});
With code clarity in mind, my opinion is that using XOR in boolean checks is not typical usage for the XOR bitwise operator. From my experience, bitwise XOR in Java is typically used to implement a mask flag toggle
behavior:
flags = flags ^ MASK;
This article by Vipan Singla explains the usage case more in detail.
If you need to use bitwise XOR as in your example, comment why you use it, since it's likely to require even a bitwise literate audience to stop in their tracks to understand why you are using it.
You can add the event using the Event API like Tristan outlined and you can also add a Google Calendar event which shows up in the iOS calendar.
using Google's API Objective-C Client
- (void)addAnEvent {
// Make a new event, and show it to the user to edit
GTLCalendarEvent *newEvent = [GTLCalendarEvent object];
newEvent.summary = @"Sample Added Event";
newEvent.descriptionProperty = @"Description of sample added event";
// We'll set the start time to now, and the end time to an hour from now,
// with a reminder 10 minutes before
NSDate *anHourFromNow = [NSDate dateWithTimeIntervalSinceNow:60*60];
GTLDateTime *startDateTime = [GTLDateTime dateTimeWithDate:[NSDate date]
timeZone:[NSTimeZone systemTimeZone]];
GTLDateTime *endDateTime = [GTLDateTime dateTimeWithDate:anHourFromNow
timeZone:[NSTimeZone systemTimeZone]];
newEvent.start = [GTLCalendarEventDateTime object];
newEvent.start.dateTime = startDateTime;
newEvent.end = [GTLCalendarEventDateTime object];
newEvent.end.dateTime = endDateTime;
GTLCalendarEventReminder *reminder = [GTLCalendarEventReminder object];
reminder.minutes = [NSNumber numberWithInteger:10];
reminder.method = @"email";
newEvent.reminders = [GTLCalendarEventReminders object];
newEvent.reminders.overrides = [NSArray arrayWithObject:reminder];
newEvent.reminders.useDefault = [NSNumber numberWithBool:NO];
// Display the event edit dialog
EditEventWindowController *controller = [[[EditEventWindowController alloc] init] autorelease];
[controller runModalForWindow:[self window]
event:newEvent
completionHandler:^(NSInteger returnCode, GTLCalendarEvent *event) {
// Callback
if (returnCode == NSOKButton) {
[self addEvent:event];
}
}];
}
I had the same problem. I installed "XCode: development tools" from the app store and it fixed the problem for me.
I think this link will help: https://itunes.apple.com/us/app/xcode/id497799835?mt=12&ls=1
Credit to Yann Ramin for his advice. I think there is a better solution with links, but this was easy and fast.
Good luck!
If an object's property may refer to some other object then you can test that for undefined before trying to use its properties:
if (thing && thing.foo)
alert(thing.foo.bar);
I could update my answer to better reflect your situation if you show some actual code, but possibly something like this:
function someFunc(parameterName) {
if (parameterName && parameterName.foo)
alert(parameterName.foo.bar);
}
I guess what you are trying to do is add Microsoft.Office.Interop.Excel
with using
statement with out adding its reference in your application, in that case it wont be found. Before calling it with using
statement you need to add a reference to ur application. Right click on References
and add the Excel Interop
reference.

A more cross-browser friendly and more optimal solution will be to use the splice
method to empty the content of the array A as below:
A.splice(0, A.length);
just create folders _cache/tmp
under .npm
manually at location /Users/marknorgate/.npm/_cacache/tmp
and run your command with administrator access
Use a HashSet<T>
. For example:
var items = "A B A D A C".Split(' ');
var unique_items = new HashSet<string>(items);
foreach (string s in unique_items)
Console.WriteLine(s);
prints
A B D C
#mybox:hover { display: none; }
#mybox:hover { visibility: hidden; }
#mybox:hover { background: none; }
#mybox:hover { color: green; }
though it should be noted that IE6 and below wont listen to the hover when it's not on an A tag. For that you have to incorporate JavaScript to add a class to the div during the hover.
There is a CSS 'length value' of ch

to install just the signingtools from the winsdksetup.exe (available at the same url as the windows sdk iso mentioned above) this is an option to, straight from the Dockerfile i'm working in: RUN powershell Start-Process winsdksetup.exe -ArgumentList '/features OptionId.SigningTools', '/q', '/ceip off', '/norestart', -NoNewWindow -Wait
so if you're in windows then that'd be: winsdksetup.exe /features OptionId.SigningTools
winsdksetup /h gives you the options, so i won't summarise them here. I include the dockerfile snippet, as that is what i started my day looking for the solution for.
I had a similar problem. It turned out, I was including an old header file of the same name from an old folder. I deleted the old file changed the #include directive to point to my new file and all was good.
Thank for the question. But I have found my own solution to this problem. At first, I created a method
public T GetSettingsWithDictionary<T>() where T:new()
{
IConfigurationRoot _configurationRoot = new ConfigurationBuilder()
.AddXmlFile($"{Assembly.GetExecutingAssembly().Location}.config", false, true).Build();
var instance = new T();
foreach (var property in typeof(T).GetProperties())
{
if (property.PropertyType == typeof(Dictionary<string, string>))
{
property.SetValue(instance, _configurationRoot.GetSection(typeof(T).Name).Get<Dictionary<string, string>>());
break;
}
}
return instance;
}
Then I used this method to produce an instance of a class
var connStrs = GetSettingsWithDictionary<AuthMongoConnectionStrings>();
I have the next declaration of class
public class AuthMongoConnectionStrings
{
public Dictionary<string, string> ConnectionStrings { get; set; }
}
and I store my setting in App.config
<configuration>
<AuthMongoConnectionStrings
First="first"
Second="second"
Third="33" />
</configuration>

This may seem slightly off topic but this was the post I came across when wondering what happens when you read a column as a dateTime in c#. The post reflects the information I would have liked to be able to find about this mechanism. If you worry about utc and timezones then read on
I did a little more research as I'm always very wary of DateTime as a class because of its automatic assumptions about what timezone you are using and because it is way too easy to confuse local times and utc times.
What I'm trying to avoid here is DateTime going 'oh look the computer I'm being run on is in timezone x, therefore this time must also be in timezone x, when I get asked for my values I'll reply as if I'm in that timezone'
I was trying to read a datetime2
column.
The date time you will get back from sql server will end up being of Kind.Unspecified
this seems to mean it gets treated like UTC, which is what I wanted.
When reading a date
column you also have to read it as a DateTime
even though it has no time and is even more prone to screwing up by timezones (as it is on midnight).
I'd certainly consider this to be safer way of reading the DateTime as I suspect it can probably be modified by either settings in sql server or static settings in your c#:
var time = reader.GetDateTime(1);
var utcTime = new DateTime(time.Ticks, DateTimeKind.Utc);
From there you can get the components (Day, Month, Year) etc and format how you like.
If what you have is actually a date + a time then Utc might not be what you want there - since you are mucking around on the client you may need to convert it to a local time first (depending on what the meaning of the time is). However that opens up a whole can of worms.. If you need to do that I'd recommend using a library like noda time. There is TimeZoneInfo
in the standard library but after briefly investigating it, it doesn't seem to have a proper set of timezones. You can see the list provided by TimeZoneInfo
by using the method TimeZoneInfo.GetSystemTimeZones();
I also discovered sql server management studio doesn't convert times to local time before displaying them. Which is a relief!
If you want to keep it simple, this should suffice:
function parseIsoDatetime(dtstr) {
var dt = dtstr.split(/[: T-]/).map(parseFloat);
return new Date(dt[0], dt[1] - 1, dt[2], dt[3] || 0, dt[4] || 0, dt[5] || 0, 0);
}
note parseFloat is must, parseInt doesn't always work. Map requires IE9 or later.
Works for formats:
Not valid for timezones, see other answers about those.

When I added IIS_IUSRS permission to site folder - resources, like js and css, still were unaccessible (error 401, forbidden). However, when I added IUSR - it became ok. So for sure "you CANNOT remove the permissions for IUSR without worrying", dear @Travis G@
To facilitate svg editing you can use an intermediate function:
function getNode(n, v) {
n = document.createElementNS("http://www.w3.org/2000/svg", n);
for (var p in v)
n.setAttributeNS(null, p, v[p]);
return n
}
Now you can write:
svg.appendChild( getNode('rect', { width:200, height:20, fill:'#ff0000' }) );
Example (with an improved getNode function allowing camelcase for property with dash, eg strokeWidth > stroke-width):
function getNode(n, v) {_x000D_
n = document.createElementNS("http://www.w3.org/2000/svg", n);_x000D_
for (var p in v)_x000D_
n.setAttributeNS(null, p.replace(/[A-Z]/g, function(m, p, o, s) { return "-" + m.toLowerCase(); }), v[p]);_x000D_
return n_x000D_
}_x000D_
_x000D_
var svg = getNode("svg");_x000D_
document.body.appendChild(svg);_x000D_
_x000D_
var r = getNode('rect', { x: 10, y: 10, width: 100, height: 20, fill:'#ff00ff' });_x000D_
svg.appendChild(r);_x000D_
_x000D_
var r = getNode('rect', { x: 20, y: 40, width: 100, height: 40, rx: 8, ry: 8, fill: 'pink', stroke:'purple', strokeWidth:7 });_x000D_

in hibernate 5.x, you should add set hibernate.id.new_generator_mappings to false in hibernate.cfg.xml
<session-factory>
......
<property name="show_sql">1</property>
<property name="hibernate.id.new_generator_mappings">false</property>

A generic solution especially for Windows Edge browser (as the -ms-user-select: none; CSS rule doesn't work):
window.ondragstart = function() {return false}
Note: This can save you having to add draggable="false"
to every img
tag when you still need the click event (i.e. you can't use pointer-events: none
), but don't want the drag icon image to appear.
Simplified example (with counter):
With Me.lstbox
.ColumnCount = 2
.ColumnWidths = "60;60"
.AddItem
.List(i, 0) = Company_ID
.List(i, 1) = Company_name
i = i + 1
end with
Make sure to start the counter with 0, not 1 to fill up a listbox.
I agree with aberrant80.
For enums, I test them only when they actually have methods in them. If it's a pure value-only enum like your example, I'd say don't bother.
But since you're keen on testing it, going with your second option is much better than the first. The problem with the first is that if you use an IDE, any renaming on the enums would also rename the ones in your test class.
I would expand on it by adding that unit testings an Enum can be very useful. If you work in a large code base, build time starts to mount up and a unit test can be a faster way to verify functionality (tests only build their dependencies). Another really big advantage is that other developers cannot change the functionality of your code unintentionally (a huge problem with very large teams).
And with all Test Driven Development, tests around an Enums Methods reduce the number of bugs in your code base.
Simple Example
public enum Multiplier {
DOUBLE(2.0),
TRIPLE(3.0);
private final double multiplier;
Multiplier(double multiplier) {
this.multiplier = multiplier;
}
Double applyMultiplier(Double value) {
return multiplier * value;
}
}
public class MultiplierTest {
@Test
public void should() {
assertThat(Multiplier.DOUBLE.applyMultiplier(1.0), is(2.0));
assertThat(Multiplier.TRIPLE.applyMultiplier(1.0), is(3.0));
}
}
According to the website, sizeof()
is an alias of count()
, so they should be running the same code. Perhaps sizeof()
has a little bit of overhead because it needs to resolve it to count()
? It should be very minimal though.
I believe that you need to use CharSequence. You can find an example here.
You can use Function.Caller to get the calling function. The old method using argument.caller is considered obsolete.
The following code illustrates its use:
function Hello() { return Hello.caller;}
Hello2 = function NamedFunc() { return NamedFunc.caller; };
function main()
{
Hello(); //both return main()
Hello2();
}
Notes about obsolete argument.caller: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/arguments/caller
Be aware Function.caller is non-standard: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/caller
In our case, the reason that the c++ version bson was not found was because we were behind a corporate proxy and something in the BSON build process needs to reach out to fetch files. When we looked in node_modules/bson/builderror.log
, we saw an error like this:
gyp WARN install got an error, rolling back install
gyp ERR! configure error
gyp ERR! stack Error: connect ECONNREFUSED
gyp ERR! stack at errnoException (net.js:904:11)
gyp ERR! stack at Object.afterConnect [as oncomplete] (net.js:895:19)
Which suggested that the proxy might be the issue. Setting the http_proxy
and https_proxy
environment variables solved it.
In XML there can be only one root element - you have two - heading
and song
.
If you restructure to something like:
<?xml version="1.0" encoding="UTF-8"?>
<song>
<heading>
The Twelve Days of Christmas
</heading>
....
</song>
The error about well-formed XML on the root level should disappear (though there may be other issues).
For people who find this old posting on the web by searching for the error message, there is another possible cause of the problem.
You could just have a typo in your call to the script, even if you have already done the things described in the other excellent answer. So check to make sure you can used the right spelling in your script tags.
Bind a change
handler, then just uncheck all of the checkboxes, apart from the one checked:
$('input.example').on('change', function() {
$('input.example').not(this).prop('checked', false);
});
I already have the Studio installed. But without starting (not installing) the Android Studio you can directly start the emulator with

In all this I don't see the answer I would go to first.
This isn't exactly a direct answer to the question, but it's a potential solution to the problem.
Just build the list backwards in the first place. If you can, use a LinkedList instead of an ArrayList and when you add items use "Push" instead of add. The list will be built in the reverse order and will then stream correctly without any manipulation.
This won't fit cases where you are dealing with primitive arrays or lists that are already used in various ways but does work well in a surprising number of cases.
I have had the same problem, as I have pictures with many different widths which I load only with height info. Setting a width allows the browser to stretch and squeeze the picture. I solve the problem by having the text line just before the image_tag line centred (also getting rid of float: left;). I would have liked the text to be left aligned, but this is a minor inconvienence, that I can tolerate.
The String#replaceAll()
interprets the argument as a regular expression. The \
is an escape character in both String
and regex
. You need to double-escape it for regex:
string.replaceAll("\\\\", "\\\\\\\\");
But you don't necessarily need regex for this, simply because you want an exact character-by-character replacement and you don't need patterns here. So String#replace()
should suffice:
string.replace("\\", "\\\\");
Update: as per the comments, you appear to want to use the string in JavaScript context. You'd perhaps better use StringEscapeUtils#escapeEcmaScript()
instead to cover more characters.

set_include_path(get_include_path() . $_SERVER["DOCUMENT_ROOT"] . "/mysite/php/includes/");
Also this can help.See set_include_path()
is just going to look for a div with class="outer inner", is that correct?
No, '.outer .inner'
will look for all elements with the .inner class that also have an element with the .outer class as an ancestor. '.outer.inner'
(no space) would give the results you're thinking of.
'.outer > .inner'
will look for immediate children of an element with the .outer class for elements with the .inner class.
Both '.outer .inner'
and '.outer > .inner'
should work for your example, although the selectors are fundamentally different and you should be wary of this.
It is not possible to save file locally without involving the local client (browser machine) as I could be a great threat to client machine. You can use link to download that file. If you want to store something like Json data on local machine you can use LocalStorage provided by the browsers, Web Storage
Your question is a little unclear. If you're generating hostDict
in a loop:
with open('data.txt', 'a') as outfile:
for hostDict in ....:
json.dump(hostDict, outfile)
outfile.write('\n')
If you mean you want each variable within hostDict
to be on a new line:
with open('data.txt', 'a') as outfile:
json.dump(hostDict, outfile, indent=2)
When the indent
keyword argument is set it automatically adds newlines.

// there was a collision

I've had a related issue in connection with Glassfish server debugging in Eclipse. This was brought about by loading the source code from a different repository (changing from SVN to GitHub). In the process, the wrong compiled classes were used by the Glassfish server and hence, the source and run time would be out of sync with break points appearing on empty lines.
To solve this, rename or delete the top folder of the classes directory and Glassfish will recreate the whole class directory tree including updating the class files with the correctly compiled version.
The classes directory is located in: /workspace/glassfish3122eclipsedefaultdomain/eclipseApps/< your Web Application>/WEB-INF/classes
There's a modern native alternative: File implements Blob, so we can call Blob.text().
async function readText(event) {
const file = event.target.files.item(0)
const text = await file.text();
document.getElementById("output").innerText = text
}
_x000D_
<input type="file" onchange="readText(event)" />
<pre id="output"></pre>
_x000D_
Currently (September 2020) this is supported in Chrome and Firefox, for other Browser you need to load a polyfill, e.g. blob-polyfill.
>>> import os
>>> os.system('cd c:\mydir')
In fact, os.system()
can execute any command that windows command prompt can execute, not just change dir.
Personally (and given what I know, i.e., Java and axis), I'd generate a Java data model from the .xsd files (Axis 2 can do this), and then add an interface to describe my web service that uses that model, and then generate a WSDL from that interface.
Because .NET has all these features as well, it must be possible to do all this in that ecosystem as well.
You can also use package plyr
, which is somehow more versatile:
library(plyr)
ddply(d, .(Name), summarize, Rate1=mean(Rate1), Rate2=mean(Rate2))

If you were using SQL 2012 or above you could use the CONCAT function:
SELECT CONCAT(field1, field2, field3) FROM table1
NULL fields won't break your concatenation.
@bummi - Thanks for the comment - edited my answer to correspond to it.
You're using S_ISREG()
and S_ISDIR()
correctly, you're just using them on the wrong thing.
In your while((dit = readdir(dip)) != NULL)
loop in main
, you're calling stat
on currentPath
over and over again without changing currentPath
:
if(stat(currentPath, &statbuf) == -1) {
perror("stat");
return errno;
}
Shouldn't you be appending a slash and dit->d_name
to currentPath
to get the full path to the file that you want to stat
? Methinks that similar changes to your other stat
calls are also needed.
I think a better solution for this problem is to use maven-install-plugin to automatically install the files at install time. This is how I set it up for my project.
First, add the path (where you store the local .jars) as a property.
<properties>
<local.sdk>/path/to/jar</local.sdk>
</properties>
Then, under plugins
add a plugin to install the jars when compiling.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<id>1</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<file>${local.sdk}/lib/impl/appengine-api.jar</file>
</configuration>
</execution>
<execution>
<id>appengine-api-stubs</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api-stubs</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<file>${local.sdk}/lib/impl/appengine-api-stubs.jar</file>
</configuration>
</execution>
</executions>
</plugin>
Finally, in dependencies, you can add the jars
<dependency>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api-stubs</artifactId>
<version>1.0</version>
<scope>test</scope>
</dependency>
By Setting up your project like this, the project will continue to build even when you take it to another computer (given that it has all the jar files in the path specified by the property local.sdk
).
For groupId
use a unique name just to make sure that there are no conflicts.
Now when you mvn install
or mvn test
local jars will be added automatically.
I found a reference that suggested adding the following to eclipse.ini
-Dswt.enable.autoScale=true
-Dswt.autoScale=200
-Dswt.autoScale.method=nearest
This doubled the size of the icons for me on Windows 10. I am using Eclipse Version: 2020-03 (4.15.0)
Just to continue to all the answers that were given here, especially @James Lanes
the size of the integer type can be expressed by this formula:
total range = (2 ^ bit system)
lower limit = -(2 ^ bit system)*0.5 upper limit = ((2 ^ bit system)*0.5) - 1
Best C# Telnet Lib I've found is called Minimalistic Telnet. Very easy to understand, use and modify. It works great for the Cisco routers I need to configure.
to load a KeyStore, you'll need to tell it the type of keystore it is (probably jceks), provide an inputstream, and a password. then, you can load it like so:
KeyStore ks = KeyStore.getInstance(TYPE_OF_KEYSTORE);
ks.load(new FileInputStream(PATH_TO_KEYSTORE), PASSWORD);
this can throw a KeyStoreException, so you can surround in a try block if you like, or re-throw. Keep in mind a keystore can contain multiple keys, so you'll need to look up your key with an alias, here's an example with a symmetric key:
SecretKeyEntry entry = (KeyStore.SecretKeyEntry)ks.getEntry(SOME_ALIAS,new KeyStore.PasswordProtection(SOME_PASSWORD));
SecretKey someKey = entry.getSecretKey();
Winston is a pretty good logging library. You can write logs out to a file using it.
Code would look something like:
var winston = require('winston');
var logger = new (winston.Logger)({
transports: [
new (winston.transports.Console)({ json: false, timestamp: true }),
new winston.transports.File({ filename: __dirname + '/debug.log', json: false })
],
exceptionHandlers: [
new (winston.transports.Console)({ json: false, timestamp: true }),
new winston.transports.File({ filename: __dirname + '/exceptions.log', json: false })
],
exitOnError: false
});
module.exports = logger;
You can then use this like:
var logger = require('./log');
logger.info('log to file');
There is new method in SQL Server 2017:
SELECT STRING_AGG (column, ',') AS column FROM Table;
that will produce 1,3,5,9
for you
ssh -t -t [email protected] << EOF
echo SOMEPASSWORD | sudo -S do something
sudo do something else
exit
EOF
Here's a future-proof approach.
Combining @CamHart's and @Yuval's suggestions with @RoshOxymoron's accepted answer has the benefit of avoiding:
_hidden
and potentially deprecated methodsSo I think this plays nice with future python versions (tested on 2.7.3 and 3.3.2):
from __future__ import print_function
import inspect
def bar():
print("my name is '{}'".format(inspect.currentframe().f_code.co_name))
It's not how they work. You "start" a marquee style progress bar by making it visible, you stop it by hiding it. You could change the Style property.
For an easy and appropriate way of doing this, first download a prepackaged release of freeglut from here. Then read its Readme.txt.
I copied some important parts of that package here:
... Create a folder on your PC which is readable by all users, for example “C:\Program Files\Common Files\MSVC\freeglut\” on a typical Windows system. Copy the “lib\” and “include\” folders from this zip archive to that location ... freeglut DLL can be placed in the same folder as your application...
... Open up the project properties, and select “All Configurations” (this is necessary to ensure our changes are applied for both debug and release builds). Open up the “general” section under “C/C++”, and configure the “include\” folder you created above as an “Additional Include Directory”. If you have more than one GLUT package which contains a “glut.h” file, it’s important to ensure that the freeglut include folder appears above all other GLUT include folders ... Open up the “general” section under “Linker”, and configure the “lib\” folder you created above as an “Additional Library Directory”...
I recommend the answer posted by Martin.
But you seem to be concerned about your queries getting too complex:
To create localized table for every table is making design and querying complex...
So you might be thinking, that instead of writing simple queries like this:
SELECT price, name, description FROM Products WHERE price < 100
...you would need to start writing queries like that:
SELECT
p.price, pt.name, pt.description
FROM
Products p JOIN ProductTranslations pt
ON (p.id = pt.id AND pt.lang = "en")
WHERE
price < 100
Not a very pretty perspective.
But instead of doing it manually you should develop your own database access class, that pre-parses the SQL that contains your special localization markup and converts it to the actual SQL you will need to send to the database.
Using that system might look something like this:
db.setLocale("en");
db.query("SELECT p.price, _(p.name), _(p.description)
FROM _(Products p) WHERE price < 100");
And I'm sure you can do even better that that.
The key is to have your tables and fields named in uniform way.
The Log class:
API for sending log output.
Generally, use the
Log.v()
Log.d()
Log.i()
Log.w()
andLog.e()
methods.The order in terms of verbosity, from least to most is
ERROR
,WARN
,INFO
,DEBUG
,VERBOSE
. Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.
Outside of Android, System.out.println(String msg)
is used.
A POST request can include a query string, however normally it doesn't - a standard HTML form with a POST action will not normally include a query string for example.

Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :
SO_REUSEPORT (since Linux 3.9) Permits multiple AF_INET or AF_INET6 sockets to be bound to an identical socket address. This option must be set on each socket (including the first socket) prior to calling bind(2) on the socket. To prevent port hijacking, all of the processes binding to the same address must have the same effective UID. This option can be employed with both TCP and UDP sockets.
As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.
You can set theses two options before calling bind like this :
int reuse = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
perror("setsockopt(SO_REUSEADDR) failed");
#ifdef SO_REUSEPORT
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0)
perror("setsockopt(SO_REUSEPORT) failed");
#endif
Try this code, works 100% for me:
FOR Landscape:
<head>
<style type="text/css">
@page{
size: auto A4 landscape;
margin: 3mm;
}
</style>
</head>
FOR Portait:
<head>
<style type="text/css">
@page{
size: auto;
margin: 3mm;
}
</style>
</head>
For web application, i normally will write this method and just call it with the key.
private String GetConfigValue(String key)
{
return System.Web.Configuration.WebConfigurationManager.AppSettings[key].ToString();
}
You (or Joomla) is likely including this file multiple times. Enclose your function in a conditional block:
if (!function_exists('parseDate')) {
// ... proceed to declare your function
}
BufferedReader
can't wrap an InputStream
directly. It wraps another Reader
. In this case you'd want to do something like:
BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
Alternatively, I would suggest turning interactive on in the beginning and at the very last plot, turn it off. All will show up, but they will not disappear as your program will stay around until you close the figures.
import matplotlib.pyplot as plt
from matplotlib import interactive
plt.figure(1)
... code to make figure (1)
interactive(True)
plt.show()
plt.figure(2)
... code to make figure (2)
plt.show()
plt.figure(3)
... code to make figure (3)
interactive(False)
plt.show()
When you are using a virtualenv
, you can specify a requirements.txt
file to install all the dependencies.
A typical usage:
$ pip install -r requirements.txt
The packages need to be in a specific format for pip
to understand, which is
feedparser==5.1.3
wsgiref==0.1.2
django==1.4.2
...
That is the "requirements format".
Here, django==1.4.2
implies install django
version 1.4.2
(even though the latest is 1.6.x).
If you do not specify ==1.4.2
, the latest version available would be installed.
You can read more in "Virtualenv and pip Basics", and the official "Requirements File Format" documentation.
Do i need to modify the headers and just echo it or something?
exactly.
Send a header("content-type: image/your_image_type");
and the data afterwards.
You should define source code encoding, add this to the top of your script:
# -*- coding: utf-8 -*-
The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:
import sys
print sys.getdefaultencoding()
Also see:
I found myself happy with this one:
string = """This is a
very long string,

I used Blorgbeard's above solution which is actually great in my opinion. Then I enhanced it as follows:
Use it like this:
@echo off
ansicon -p
set /p pwd=Password:ESC[0;37;47m
echo ESC[0m
This switches the console to gray on gray for your password entry and switches back when you are done. The ESC should actually be an unprintable character, which you can copy over from the downloaded sample text file (appears like a left-arrow in Notepad) into your batch file. You can use the sample text file to find the codes for all color combinations.
If you are not admin of the machine, you will probably be able to install the files in a non-system directory, then you have to append the directory to the PATH in your script before calling the program and using the escape sequences. This could even be the current directory probably, if you need a non-admin distributable package of just a few files.
In .net VB - you could achieve control over columns and rows with the following in your razor file:
@Html.EditorFor(Function(model) model.generalNotes, New With {.htmlAttributes = New With {.class = "someClassIfYouWant", .rows = 5,.cols=6}})
I successfully used
diff "${file1}" "${file2}" | grep "<" | sed 's/^<//g' > "${diff_file}"
Outputting the difference to a file.
SELECT * FROM TABLE_NAME SAMPLE(1)
Will give you olny an approximate 1% share rather than exactly 1/100 of the number of observations. The likely reason is than Oracle generates a random flag for each observation as to whether include in in the sample that it generates. The argument 1 (1%) in such a generation process takes the role of probability of each observation's being selected into the sample.
If this is true, the actual distribution of sample sizes will be binomial.
I would recommend using prototype's callback.isFunction()
.
They've figured out the difference and you can count on their reason.
I guess other JS frameworks have such things, too.
instanceOf
wouldn't work on functions defined in other windows, I believe.
Their Function is different than your window.Function
.
To get you phone number you can read a plist file. It will not work on non-jailbroken iDevices:
NSString *commcenter = @"/private/var/wireless/Library/Preferences/com.apple.commcenter.plist";
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:commcenter];
NSString *PhoneNumber = [dict valueForKey:@"PhoneNumber"];
NSLog([NSString stringWithFormat:@"Phone number: %@",PhoneNumber]);
I don't know if Apple allow this but it works on iPhones.
A break will allow you continue processing in the function. Just returning out of the switch is fine if that's all you want to do in the function.
This worked for me on iOS 5.0 simulator.
Run the app on the simulator.
Go to the path where you can see something like this:
/Users/arshad/Library/Application\ Support/iPhone\ Simulator/5.0/Applications/34BC3FDC-7398-42D4-9114-D5FEFC737512/…
Copy all the package contents including the app, lib, temp and Documents.
Clear all the applications installed on the simulator so that it is easier to see what is happening.
Run a pre-existing app you have on your simulator.
Look for the same package content for that application as in step 3 and delete all.
Paste the package contents that you have previously copied.
Close the simulator and start it again. The new app icon of the intended app will replace the old one.
If you have a collection of objects that you load using stored procedure you can also use LoadFromCollection
.
using (ExcelPackage package = new ExcelPackage(file))
{
ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("test");
worksheet.Cells["A1"].LoadFromCollection(myColl, true, OfficeOpenXml.Table.TableStyles.Medium1);
package.Save();
}

I found this maven
repo where you could download from directly a zip
file containing all the jars you need.
The solution I prefer is using Maven
, it is easy and you don't have to download each jar
alone. You can do it with the following steps:
Create an empty folder anywhere with any name you prefer, for example spring-source
Create a new file named pom.xml
Copy the xml below into this file
Open the spring-source
folder in your console
Run mvn install
After download finished, you'll find spring jars in /spring-source/target/dependencies
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Also, if you need to download any other spring project, just copy the dependency
configuration from its corresponding web page.
For example, if you want to download Spring Web Flow
jars, go to its web page, and add its dependency
configuration to the pom.xml
dependencies
, then run mvn install
again.

In the absence of duck typing as you can use it in Python, C# relies on interfaces to provide abstractions. If the dependencies of a class were all concrete types, you could not pass in any other type - using interfaces you can pass in any type that implements the interface.
static
renders variable local to the file which is generally a good thing, see for example this Wikipedia entry.
If a pipeline is too complicated to wrap in $(...)
, consider writing a function. Any local variables available at the time of definition will be accessible.
function getHash {
genhash --use-ssl -s $IP -p 443 --url $URL | grep MD5 | grep -c $MD5
}
hash=$(getHash)

Executive summary / TL;DR:
Try doing a find & replace of "=" with "=". Yes, replace the equals sign with itself. For my scenario, it forced everything to update.
Background:
I frequently make formulas across multiple columns then concatenate them together. After doing such, I'll copy & paste them as values to extract my created formula. After this process, they're typically stuck displaying a formula, and not displaying a value, unless I enter the cell and press Enter. Pressing F2 & Enter repeatedly is not fun.
You can simply try this and it should work in most cases, feel free to correct me if I am wrong :
function hereLies(obj) {
if(obj.val() != "") {
//Do this here
}
}
Where obj
is the object of your textarea

It would make for a handy function. Also, note I'm using STUFF instead of SUBSTRING.
create function str2uniq(@s varchar(50)) returns uniqueidentifier as begin
-- just in case it came in with 0x prefix or dashes...
set @s = replace(replace(@s,'0x',''),'-','')
-- inject dashes in the right places
set @s = stuff(stuff(stuff(stuff(@s,21,0,'-'),17,0,'-'),13,0,'-'),9,0,'-')
return cast(@s as uniqueidentifier)
end
Sample Usage:
import paramiko
paramiko.util.log_to_file("paramiko.log")
# Open a transport
host,port = "example.com",22
transport = paramiko.Transport((host,port))
# Auth
username,password = "bar","foo"
transport.connect(None,username,password)
# Go!
sftp = paramiko.SFTPClient.from_transport(transport)
# Download
filepath = "/etc/passwd"
localpath = "/home/remotepasswd"
sftp.get(filepath,localpath)
# Upload
filepath = "/home/foo.jpg"
localpath = "/home/pony.jpg"
sftp.put(localpath,filepath)
# Close
if sftp: sftp.close()
if transport: transport.close()
If JDK installed but still not working.
In Eclipse follow below steps:- Window --> Preference --> Installed JREs -->Change path of JRE to JDK(add).
def window(seq, size, step=1):
# initialize iterators
iters = [iter(seq) for i in range(size)]
# stagger iterators (without yielding)
[next(iters[i]) for j in range(size) for i in range(-1, -j-1, -1)]
while(True):
yield [next(i) for i in iters]
# next line does nothing for step = 1 (skips iterations for step > 1)
[next(i) for i in iters for j in range(step-1)]
next(it)
raises StopIteration
when the sequence is finished, and for some cool reason that's beyond me, the yield statement here excepts it and the function returns, ignoring the leftover values that don't form a full window.
Anyway, this is the least-lines solution yet whose only requirement is that seq
implement either __iter__
or __getitem__
and doesn't rely on itertools
or collections
besides @dansalmo's solution :)
For Dot Net Core 3, Microsoft.Data.SqlClient should be used.
In Active Directory environment, it's important to know:
All member machines synchronizes with any domain controller.
In a domain, all domain controllers synchronize from the PDC Emulator (PDCe) of that domain.
The PDC Emulator of a domain should synchronize with local or NTP.
It's important to consider this when setting the time in vmware or configuring the time sync.

Since none of these answers deal with the cause I encountered, for this problem, I will add my answer here as well.
In my case, it was a copy pasting code problem. We had a TestProjectA
where there are specific type of tests that we want to pull out to its own test project - TestProjectB
. The problem now was that, while tests in TestProjectA
continue to show up just fine, the tests in the new TestProjectB
aren't showing up in VS Test Explorer - unless you specifically build TestProjectB
or manually right click on a test there and run it.
The cause was that in copy pasting the code over, some namespaces didn't get updated:
TestMethodA()
in TestClassA
in namespace TestProjectA.ModuleA
with filepath \TestProjectA\TestClassA.cs
TestMethodA()
in TestClassB
in namespace TestProjectA.ModuleA
with filepath \TestProjectB\TestClassB.cs
So visual Studio prints out a message in Output window that the TestId for these two are the same, and proceeds to show TestProjectA
and not TestProjectB
in Test Explorer due to the TestId clashing between the two projects. Correcting the namespace to TestProjectB.ModuleB
for \TestProjectB\TestClassB.cs
fixed the issue.

Synchronously:
if let filePath = Bundle.main.path(forResource: "imageName", ofType: "jpg"), let image = UIImage(contentsOfFile: filePath) {
imageView.contentMode = .scaleAspectFit
imageView.image = image
}
Asynchronously:
Create a method with a completion handler to get the image data from your url
func getData(from url: URL, completion: @escaping (Data?, URLResponse?, Error?) -> ()) {
URLSession.shared.dataTask(with: url, completionHandler: completion).resume()

Create a method to download the image (start the task)
func downloadImage(from url: URL) {
print("Download Started")
getData(from: url) { data, response, error in
guard let data = data, error == nil else { return }
print(response?.suggestedFilename ?? url.lastPathComponent)
print("Download Finished")
DispatchQueue.main.async() { [weak self] in
self?.imageView.image = UIImage(data: data)
}
}
}
Usage:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
print("Begin of code")
let url = URL(string: "https://cdn.arstechnica.net/wp-content/uploads/2018/06/macOS-Mojave-Dynamic-Wallpaper-transition.jpg")!
downloadImage(from: url)

The JPEXS Free Flash Decompiler has Java code to do this at in the source tree for both Chrome and Firefox (no support for Firefox's more recent cache2 though).
This *& in theory as well as in practical its possible and called as reference to pointer variable. and it's act like same.
This *& combination is used in as function parameter for 'pass by' type defining. unlike ** can also be used for declaring a double pointer variable.
The passing of parameter is divided into pass by value, pass by reference, pass by pointer.
there are various answer about "pass by" types available. however the basic we require to understand for this topic is.
pass by reference --> generally operates on already created variable refereed while passing to function e.g fun(int &a);
pass by pointer --> Operates on already initialized 'pointer variable/variable address' passing to function e.g fun(int* a);
auto addControl = [](SomeLabel** label, SomeControl** control) {
*label = new SomeLabel;
*control = new SomeControl;
// few more operation further.
};
addControl(&m_label1,&m_control1);
addControl(&m_label2,&m_control2);
addControl(&m_label3,&m_control3);
in the above example(this is the real life problem i came across) i am trying to init few pointer variable from the lambda function and for that we need to pass it by double pointer, so that comes with d-referencing of pointer for its all usage inside of that lambda + while passing pointer in function which takes double pointer, you need to pass reference to the pointer variable.
so with this same thing reference to the pointer variable, *& this combination helps. in below given way for the same example i have mentioned above.
auto addControl = [](SomeLabel*& label, SomeControl*& control) {
label = new SomeLabel;
control = new SomeControl;
// few more operation further.
};
addControl(m_label1,m_control1);
addControl(m_label2,m_control2);
addControl(m_label3,m_control3);
so here you can see that you neither require d-referencing nor we require to pass reference to pointer variable while passing in function, as current pass by type is already reference to pointer.
Hope this helps :-)
It sounds like you may be wanting to access the viewport of the device. You can do this by inserting this meta tag in your header.
<meta name="viewport" content="width=device-width, initial-scale=1.0">
for example I faced this in express node.js when trying to create route for paths not starting with /internal
app.get(`\/(?!internal).*`, (req, res)=>{
and after long trying it just worked when passing it as a RegExp Object using new RegExp()
app.get(new RegExp("\/(?!internal).*"), (req, res)=>{
this may help if you are getting this common issue in routing
This is the only solution possible for using nothing but cut:
echo "s.t.r.i.n.g." | cut -d'.' -f2- [repeat_following_part_forever_or_until_out_of_memory:] | cut -d'.' -f2-
Using this solution, the number of fields can indeed be unknown and vary from time to time. However as line length must not exceed LINE_MAX characters or fields, including the new-line character, then an arbitrary number of fields can never be part as a real condition of this solution.
Yes, a very silly solution but the only one that meets the criterias I think.
Disclosure: I am one of the lombok developers. I might be biased :-)
I strongly suggest installing Lombok via executing the lombok jar: java -jar lombok.jar
The spaces in the path might be a problem.
Also, you'll need to use lombok version 1.14.8 (or higher) to have Luna support.
Please check in the About Eclipse screen if lombok is installed correctly.

According to this, you will need .NET 4.5 installed. For more details, visit the webpage. The gist of it is that after you have .NET 4.5 installed, your 4.0 apps will use the 4.5 System.dll. You can enable TLS 1.2 in two ways:
ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

Use os.walk to iterate recursively over directory content:
import os
root_dir = '.'
for directory, subdirectories, files in os.walk(root_dir):
for file in files:
print os.path.join(directory, file)
No real difference between os.system and subprocess.call here - unless you have to deal with strangely named files (filenames including spaces, quotation marks and so on). If this is the case, subprocess.call is definitely better, because you don't need to do any shell-quoting on file names. os.system is better when you need to accept any valid shell command, e.g. received from user in the configuration file.
For a precise answer to this question on "How to send data via intent from an Activity to Service", Is that you have to override the onStartCommand()
method which is where you receive the intent object:
When you create a Service
you should override the onStartCommand()
method so if you closely look at the signature below, this is where you receive the intent
object which is passed to it:
public int onStartCommand(Intent intent, int flags, int startId)
So from an activity you will create the intent object to start service and then you place your data inside the intent object for example you want to pass a UserID
from Activity
to Service
:
Intent serviceIntent = new Intent(YourService.class.getName())
serviceIntent.putExtra("UserID", "123456");
context.startService(serviceIntent);
When the service is started its onStartCommand()
method will be called so in this method you can retrieve the value (UserID) from the intent object for example
public int onStartCommand (Intent intent, int flags, int startId) {
String userID = intent.getStringExtra("UserID");
return START_STICKY;
}
Note: the above answer specifies to get an Intent with getIntent()
method which is not correct in context of a service
Some people think that VCS systems have to be complicated. They encourage inventing terms and concepts on the field. They would probably think that numerous PhDs on the subject would be interesting. Among those are probably the ones that designed Git.
Mercurial is designed with a different mentality. Developers should not care much about VCS, and they should instead spend their time on their main function: software engineering. Mercurial allows users to use and happily abuse the system without letting them make any non-recoverable mistakes.
Any professional tool must come with a clearly designed and intuitive CLI. Mercurial users can do most of the work by issuing simple commands without any strange options. In Git double dash, crazy options are the norm. Mercurial has a substantial advantage if you are a CLI person (and to be honest, any self-respecting Software Engineer should be).
To give an example, suppose you do a commit by mistake. You forgot to edit some files. To undo you action in Mercurial you simply type:
$ hg rollback
You then get a message that the system undos your last transaction.
In Git you have to type:
$ git reset --soft HEAD^
So ok suppose you have an idea what reset is about. But in addition you have to know what "--soft" and "--hard" resets are (any intuitive guesses?). Oh and of course don't forget the '^' character in the end! (now what in Ritchie's name is that...)
Mercurial's integration with 3rd party tools like kdiff3 and meld is much better as well. Generate your patches merge your branches without much fuss. Mercurial also includes a simple http server that you activate by typing
hg serve
And let others browse your repository.
The bottom line is, Git does what Mercurial does, in a much more complicated way and with a far inferior CLI. Use Git if you want to turn the VCS of your project into a scientific-research field. Use Mercurial if you want to get the VCS job done without caring much about it, and focus on your real tasks.
I don't know if it's possible to run it just like that.
I usually first copy it with scp and then log in to run it.
scp foo.sh user@host:~
ssh user@host
./foo.sh
var = None
"clears the value", setting the value of the variable to "null" like value of "None", however the pointer to the variable remains.
del var
removes the definition for the variable totally.
In case you want to use the variable later, e.g. set a new value for it, i.e. retain the variable, None
would be better.
To save hours of coding time, use a jquery plug-in already optimized for embedded video iframes.
I spent a couple days trying to integrate Vimeo's moogaloop API with jquery tools unsuccessfully. See this list for a handful of easier options.
You can use below code sample also for achieving the same
ViewCompat.setElevation(sourceView, ViewCompat.getElevation(mCardView)+1);
This is backward compatible.
Here mCardView
is a view which should be below sourceView
.
You have to install the appropriate plug-in first (i.e., XML, C#, etc.).
Formatting won't become available until you've installed the relevant plugin, and saved the file with an appropriate extension.
