In MVC5 I'd use, if your model is the datetime
string dt = Model.ToString("dd/MM/yyy");
Or if your model contains the property of the datetime
string dt = Model.dateinModel.ToString("dd/MM/yyy");
Here's the official meaning of the Formats:
https://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx
Use:
public static class StringExtensions
{
/// <summary>
/// Cut End. "12".SubstringFromEnd(1) -> "1"
/// </summary>
public static string SubstringFromEnd(this string value, int startindex)
{
if (string.IsNullOrEmpty(value)) return value;
return value.Substring(0, value.Length - startindex);
}
}
I prefer an extension method here for two reasons:
Example: f1.Substring(directorypathLength).SubstringFromEnd(1)
struct Base {
virtual void f() {}
virtual ~Base() {}
};
struct Derived : Base {
void f() override {}
~Derived() override {}
};
Base* base = new Derived;
base->f(); // calls Derived::f
base->~Base(); // calls Derived::~Derived
Virtual destructor call is no different from any other virtual function call.
For base->f()
, the call will be dispatched to Derived::f()
, and it's the same for base->~Base()
- its overriding function - the Derived::~Derived()
will be called.
Same happens when destructor is being called indirectly, e.g. delete base;
. The delete
statement will call base->~Base()
which will be dispatched to Derived::~Derived()
.
If you are not going to delete object through a pointer to its base class - then there is no need to have a virtual destructor. Just make it protected
so that it won't be called accidentally:
// library.hpp
struct Base {
virtual void f() = 0;
protected:
~Base() = default;
};
void CallsF(Base& base);
// CallsF is not going to own "base" (i.e. call "delete &base;").
// It will only call Base::f() so it doesn't need to access Base::~Base.
//-------------------
// application.cpp
struct Derived : Base {
void f() override { ... }
};
int main() {
Derived derived;
CallsF(derived);
// No need for virtual destructor here as well.
}

There is no exists

defined( $x )
and the equivalent Java is
anInteger != null
Those are the equivalents.
exists $hash{key}
Is like the Java
map.containsKey( "key" )
From your example, I think you're looking for
if ( startIn != null ) { ...
This is happening because there is no package cache in the image, you need to run:
apt-get -qq update
before installing packages, and if your command is in a Dockerfile, you'll then need:
apt-get -qq -y install curl
After that install ZSH and GIT Core:
apt-get install zsh
apt-get install git-core
Getting zsh
to work in ubuntu is weird since sh
does not understand the source command. So, you do this to install zsh
:
wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
and then you change your shell to zsh:
chsh -s `which zsh`
and then restart:
sudo shutdown -r 0

Use to_datetime
, there is no need for a format string the parser is man/woman enough to handle it:
In [51]:
pd.to_datetime(df['I_DATE'])
Out[51]:
0 2012-03-28 14:15:00
1 2012-03-28 14:17:28
2 2012-03-28 14:50:50
Name: I_DATE, dtype: datetime64[ns]
To access the date/day/time component use the dt
accessor:
In [54]:
df['I_DATE'].dt.date
Out[54]:
0 2012-03-28
1 2012-03-28
2 2012-03-28
dtype: object
In [56]:
df['I_DATE'].dt.time
Out[56]:
0 14:15:00
1 14:17:28
2 14:50:50
dtype: object
You can use strings to filter as an example:
In [59]:
df = pd.DataFrame({'date':pd.date_range(start = dt.datetime(2015,1,1), end = dt.datetime.now())})
df[(df['date'] > '2015-02-04') & (df['date'] < '2015-02-10')]
Out[59]:
date
35 2015-02-05
36 2015-02-06
37 2015-02-07
38 2015-02-08

This is really just an explaination of Yuzem's answer, but I didn't feel like this much editing should be done to someone else, and comments don't allow formatting, so...
rdom () { local IFS=\> ; read -d \< E C ;}
Let's call that "read_dom" instead of "rdom", space it out a bit and use longer variables:
read_dom () {
local IFS=\>
read -d \< ENTITY CONTENT
}
Okay so it defines a function called read_dom. The first line makes IFS (the input field separator) local to this function and changes it to >. That means that when you read data instead of automatically being split on space, tab or newlines it gets split on '>'. The next line says to read input from stdin, and instead of stopping at a newline, stop when you see a '<' character (the -d for deliminator flag). What is read is then split using the IFS and assigned to the variable ENTITY and CONTENT. So take the following:
<tag>value</tag>
The first call to read_dom
get an empty string (since the '<' is the first character). That gets split by IFS into just '', since there isn't a '>' character. Read then assigns an empty string to both variables. The second call gets the string 'tag>value'. That gets split then by the IFS into the two fields 'tag' and 'value'. Read then assigns the variables like: ENTITY=tag
and CONTENT=value
. The third call gets the string '/tag>'. That gets split by the IFS into the two fields '/tag' and ''. Read then assigns the variables like: ENTITY=/tag
and CONTENT=
. The fourth call will return a non-zero status because we've reached the end of file.
Now his while loop cleaned up a bit to match the above:
while read_dom; do
if [[ $ENTITY = "title" ]]; then
echo $CONTENT
exit
fi
done < xhtmlfile.xhtml > titleOfXHTMLPage.txt
The first line just says, "while the read_dom functionreturns a zero status, do the following." The second line checks if the entity we've just seen is "title". The next line echos the content of the tag. The four line exits. If it wasn't the title entity then the loop repeats on the sixth line. We redirect "xhtmlfile.xhtml" into standard input (for the read_dom
function) and redirect standard output to "titleOfXHTMLPage.txt" (the echo from earlier in the loop).
Now given the following (similar to what you get from listing a bucket on S3) for input.xml
:
<ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Name>sth-items</Name>
<IsTruncated>false</IsTruncated>
<Contents>
<Key>[email protected]</Key>
<LastModified>2011-07-25T22:23:04.000Z</LastModified>
<ETag>"0032a28286680abee71aed5d059c6a09"</ETag>
<Size>1785</Size>
<StorageClass>STANDARD</StorageClass>
</Contents>
</ListBucketResult>
and the following loop:
while read_dom; do
echo "$ENTITY => $CONTENT"
done < input.xml
You should get:
=>
ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/" =>
Name => sth-items
/Name =>
IsTruncated => false
/IsTruncated =>
Contents =>
Key => [email protected]
/Key =>
LastModified => 2011-07-25T22:23:04.000Z
/LastModified =>
ETag => "0032a28286680abee71aed5d059c6a09"
/ETag =>
Size => 1785
/Size =>
StorageClass => STANDARD
/StorageClass =>
/Contents =>
So if we wrote a while
loop like Yuzem's:
while read_dom; do
if [[ $ENTITY = "Key" ]] ; then
echo $CONTENT
fi
done < input.xml
We'd get a listing of all the files in the S3 bucket.
EDIT
If for some reason local IFS=\>
doesn't work for you and you set it globally, you should reset it at the end of the function like:
read_dom () {
ORIGINAL_IFS=$IFS
IFS=\>
read -d \< ENTITY CONTENT
IFS=$ORIGINAL_IFS
}
Otherwise, any line splitting you do later in the script will be messed up.
EDIT 2
To split out attribute name/value pairs you can augment the read_dom()
like so:
read_dom () {
local IFS=\>
read -d \< ENTITY CONTENT
local ret=$?
TAG_NAME=${ENTITY%% *}
ATTRIBUTES=${ENTITY#* }
return $ret
}
Then write your function to parse and get the data you want like this:
parse_dom () {
if [[ $TAG_NAME = "foo" ]] ; then
eval local $ATTRIBUTES
echo "foo size is: $size"
elif [[ $TAG_NAME = "bar" ]] ; then
eval local $ATTRIBUTES
echo "bar type is: $type"
fi
}
Then while you read_dom
call parse_dom
:
while read_dom; do
parse_dom
done
Then given the following example markup:
<example>
<bar size="bar_size" type="metal">bars content</bar>
<foo size="1789" type="unknown">foos content</foo>
</example>
You should get this output:
$ cat example.xml | ./bash_xml.sh
bar type is: metal
foo size is: 1789
EDIT 3 another user said they were having problems with it in FreeBSD and suggested saving the exit status from read and returning it at the end of read_dom like:
read_dom () {
local IFS=\>
read -d \< ENTITY CONTENT
local RET=$?
TAG_NAME=${ENTITY%% *}
ATTRIBUTES=${ENTITY#* }
return $RET
}
I don't see any reason why that shouldn't work
This should do:
$chunk = "abc\tdef\tghi";

where T: class
literally means that T has to be a class
. It can be any reference type. Now whenever any code calls your DoThis<T>()
method it must provide a class to replace T. For example if I were to call your DoThis<T>()
method then I will have to call it like following:
DoThis<MyClass>();
If your metthod is like like the following:
public IList<T> DoThis<T>() where T : class
{
T variablename = new T();
// other uses of T as a type
}
Then where ever T appears in your method, it will be replaced by MyClass. So the final method that the compiler calls , will look like the following:
public IList<MyClass> DoThis<MyClass>()
{
MyClass variablename= new MyClass();
//other uses of MyClass as a type
// all occurences of T will similarly be replace by MyClass
}
HTTP doesn't support redirection to a page using POST. When you redirect somewhere, the HTTP "Location" header tells the browser where to go, and the browser makes a GET request for that page. You'll probably have to just write the code for your page to accept GET requests as well as POST requests.
A reliable way to get the external IP address of the local machine would be to query the routing table, although we have no direct way to do it in PHP.
However we can get the system to do it for us by binding a UDP socket to a public address, and getting its address:
$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_connect($sock, "8.8.8.8", 53);
socket_getsockname($sock, $name); // $name passed by reference
// This is the local machine's external IP address
$localAddr = $name;
socket_connect
will not cause any network traffic because it's an UDP socket.

C++20 will add constexpr
strings and vectors
The following proposal has been accepted apparently: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0980r0.pdf and it adds constructors such as:
// 20.3.2.2, construct/copy/destroy
constexpr
basic_string() noexcept(noexcept(Allocator())) : basic_string(Allocator()) { }
constexpr
explicit basic_string(const Allocator& a) noexcept;
constexpr
basic_string(const basic_string& str);
constexpr
basic_string(basic_string&& str) noexcept;
in addition to constexpr versions of all / most methods.
There is no support as of GCC 9.1.0, the following fails to compile:
#include <string>
int main() {
constexpr std::string s("abc");
}
with:
g++-9 -std=c++2a main.cpp
with error:
error: the type ‘const string’ {aka ‘const std::__cxx11::basic_string<char>’} of ‘constexpr’ variable ‘s’ is not literal

The problem with accepted answer is that result string goes over the the limit, i.e. it can exceed 100 chars since strpos
will look after the offset and so your length will always be a over your limit. If the last word is long, like squirreled
then the length of your result will be 111 (to give you an idea).
A better solution is to use wordwrap
function:
function truncate($str, $length = 125, $append = '...') {
if (strlen($str) > $length) {
$delim = "~\n~";
$str = substr($str, 0, strpos(wordwrap($str, $length, $delim), $delim)) . $append;
}
return $str;
}
echo truncate("The quick brown fox jumped over the lazy dog.", 5);
This way you can be sure the string is truncated under your limit (and never goes over)
P.S. This is particularly useful if you plan to store the truncated string in your database with a fixed-with column like VARCHAR(50), etc.
P.P.S. Note the special delimiter in wordwrap. This is to make sure that your string is truncated correctly even when it contains newlines (otherwise it will truncate at first newline which you don't want).
Just some notes on timing:
If you're starting with a list, l.append(l.pop(0))
is the fastest method you can use. This can be shown with time complexity alone:
So if you are starting with deque
objects, you can deque.rotate()
at the cost of O(k). But, if the starting point is a list, the time complexity of using deque.rotate()
is O(n). l.append(l.pop(0)
is faster at O(1).
Just for the sake of illustration, here are some sample timings on 1M iterations:

I have a Joomla Module that displays stuff... and I want to be able to share that stuff on facebook and not the Page's Title Meta Description... so my workaround is to have a secret .php file on the server that gets executed when it detects the FB's

if($_SERVER['HTTP_USER_AGENT'] != 'facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)') {

I have had this problem frequently with multiple concurrent goroutines.
It may or may not be a good pattern, but I define a a struct for my workers with a quit channel and field for the worker state:
type Worker struct {
data chan struct
quit chan bool
stopped bool
}
Then you can have a controller call a stop function for the worker:
func (w *Worker) Stop() {
w.quit <- true
w.stopped = true
}
func (w *Worker) eventloop() {
for {
if w.Stopped {
return
}
select {
case d := <-w.data:
//DO something
if w.Stopped {
return
}
case <-w.quit:
return
}
}
}
This gives you a pretty good way to get a clean stop on your workers without anything hanging or generating errors, which is especially good when running in a container.

There is no updated

command, the old data is stored in the deleted

Think of an UPDATE
as a DELETE/INSERT
combination.

If you are using Spring Security ver >= 3.2, you can use the @AuthenticationPrincipal
annotation:
@RequestMapping(method = RequestMethod.GET)
public ModelAndView showResults(@AuthenticationPrincipal CustomUser currentUser, HttpServletRequest request) {
String currentUsername = currentUser.getUsername();
// ...
}
Here, CustomUser
is a custom object that implements UserDetails
that is returned by a custom UserDetailsService
.
More information can be found in the @AuthenticationPrincipal chapter of the Spring Security reference docs.
You probably need to add the namespace:

Start an Android Emulator (make sure that all supported APIs are included when you created the emulator, we needed to have the Google APIs for instance).
Then simply email yourself a link to the .apk file, and download it directly in the emulator, and click the downloaded file to install it.
The ld returned 1 exit status
error is the consequence of previous errors. In your example there is an earlier error - undefined reference to 'clrscr'
- and this is the real one. The exit status error just signals that the linking step in the build process encountered some errors. Normally exit status 0
means success, and exit status
> 0 means errors.
When you build your program, multiple tools may be run as separate steps to create the final executable. In your case one of those tools is ld
, which first reports the error it found (clrscr
reference missing), and then it returns the exit status. Since the exit status is > 0, it means an error and is reported.
In many cases tools return as the exit status the number of errors they encountered. So if ld tool finds two errors, its exit status would be 2.
Recently came upon a case where this was not true, TI C28x boards can have a sizeof pointer == 1, since a byte for those boards is 16-bits, and pointer size is 16 bits. To make matters more confusing, they also have far pointers which are 22-bits. I'm not really sure what sizeof far pointer would be.
In general, DSP boards can have weird integer sizes.
So pointer sizes can still be weird in 2020 if you are looking in weird places
This probably because of your gzip version incompatibility.
Check these points first:
which gzip
/usr/bin/gzip or /bin/gzip
It should be either /bin/gzip or /usr/bin/gzip. If your gzip points to some other gzip application please try by removing that path from your PATH env variable.
Next is
gzip -V
gzip 1.3.5 (2002-09-30)
Your problem can be resolve with these check points.

Using the FM

to_char(a, '90D90'),
to_char(a, 'FM90D99'),
rtrim(to_char(a, 'FM90D99'), to_char(0, 'D'))
from (
select 50 a from dual
union all select 50.57 from dual
union all select 5.57 from dual
union all select 0.35 from dual
union all select 0.4 from dual
)
order by a;
TO_CHA TO_CHA TO_CHA RTRIM(
------ ------ ------ ------
.35 0.35 0.35 0.35
.40 0.40 0.4 0.4
5.57 5.57 5.57 5.57
50.00 50.00 50. 50
50.57 50.57 50.57 50.57
Note that I'm using to_char(0, 'D')
to generate the character to trim, to match the decimal separator - so it looks for the same character, ,
or .
, as the first to_char
adds.
The slight downside is that you lose the alignment. If this is being used elsewhere it might not matter, but it does then you can also wrap it in an lpad
, which starts to make it look a bit complicated:
...
lpad(rtrim(to_char(a, 'FM90D99'), to_char(0, 'D')), 6)
...

Update December 8th, 2015 According to Google Support using the
googledrive.com/host/ID
method will be turned off on Aug 31st, 2016.
I just ran into this issue.
The trick is to treat your Google Drive folder like a web host.
Update April 1st, 2015
Google Drive has changed and there's a simple way to direct link to your drive. I left my previous answers below for reference but to here's an updated answer.
https://googledrive.com/host/<folder UUID>/
https://googledrive.com/host/<folder UUID>/<file name>
Which is intended functionality by Google
new Google Drive Link.
All you have to do is simple get the host URL for a publicly shared drive folder. To do this, you can upload a plain HTML file and preview it in Google Drive to find your host URL.
Here are the steps:
[edit]
I forgot to add. If you use subfolders to organize your files, you simple use the folder name as you would expect in a URL hierarchy.
https://googledrive.com/host/<your public folders id string>/images/my-image.png
What I was looking to do
I created a custom Debian image with Virtual Box for Vagrant. I wanted to share this ".box" file with colleagues so they could put the direct link into their Vagrantfile.
In the end, I needed a direct link to the actual file.
Google Drive problem
If you set the file permissions to be publicly available and create/generate a direct access link by using something like the gdocs2direct tool or just crafting the link yourself:
https://docs.google.com/uc?export=download&id=<your file id>
You will get a cookie based verification code and prompt "Google could not scan this file" prompt, which won't work for things such as wget or Vagrantfile configs.
The code that it generates is a simple code that appends GET query variable ...&confirm=###
to the string, but it's per user specific, so it's not like you can copy/paste that query variable for others.
But if you use the above "Web page hosting" method, you can get around that prompt.
I hope that helps!
You can use .getScript()
and run your code after it loads:
$.getScript("my_lovely_script.js", function(){
alert("Script loaded and executed.");
// here you can use anything you defined in the loaded script
});
You can see a better explanation here: How do I include a JavaScript file in another JavaScript file?
There was a feature request for that in vscode repo. But it was marked as extension-candidate
and closed. So, here is the extension: Indent One space
Unlike the answer below that tells you to use Ctrl+[ this extension indents code by ONE whtespace ???.
For start Activity 2 from Activity 1 and get result, you could use startActivityForResult and implement onActivityResult in Activity 1 and use setResult in Activity2.
Intent intent = new Intent(this, Activity2.class);
intent.putExtra(NUMERO1, numero1);
intent.putExtra(NUMERO2, numero2);
//startActivity(intent);
startActivityForResult(intent, MI_REQUEST_CODE);
As a slight alternative to @FazianMubasher's answer, instead of allowing NULL
for the specified column (which may for many reasons not be possible), you could also add a Conditional Split Task to branch NULL
values to an error file, or just to ignore them:
You could loop through the list and keep the tuple in a variable and then you can see both values from the same variable...
num=(0, 0)
for item in tuplelist:
if item[1]>num[1]:
num=item #num has the whole tuple with the highest y value and its x value
SELECT length(actual_project_name),actual_project_name,
SUBSTRING_INDEX(actual_project_name,'-',1) as aaaaaa,
SUBSTRING_INDEX(actual_project_name, '-', -1) as actual_project_number,
concat(SUBSTRING_INDEX(actual_project_name,'-',1),SUBSTRING_INDEX(actual_project_name, '-', -1)) as a
FROM ctts.test22
order by
SUBSTRING_INDEX(actual_project_name,'-',1) asc,cast(SUBSTRING_INDEX(actual_project_name, '-', -1) as unsigned) asc
Assuming your controller's action method is something like this:
public ActionResult AllCategories(int id = 0)
{
return View(db.Categories.Include(p => p.Products).ToList());
}
Modify your models to be something like this:
public class Product
{
[Key]
public int ID { get; set; }
public int CategoryID { get; set; }
//new code
public virtual Category Category { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public string Path { get; set; }
//remove code below
//public virtual ICollection<Category> Categories { get; set; }
}
public class Category
{
[Key]
public int CategoryID { get; set; }
public string Name { get; set; }
//new code
public virtual ICollection<Product> Products{ get; set; }
}
Then your since now the controller takes in a Category as Model (instead of a Product):
foreach (var category in Model)
{
<h3><u>@category.Name</u></h3>
<div>
<ul>
@foreach (var product in Model.Products)
{
// cut for brevity, need to add back more code from original
<li>@product.Title</li>
}
</ul>
</div>
}
UPDATED: Add ToList() to the controller return statement.
UPDATE: Another writeup here: How to add publisher in Installshield 2018 (might be better).
I am not too well informed about this issue, but please see if this answer to another question tells you anything useful (and let us know so I can evolve a better answer here): How to pass the Windows Defender SmartScreen Protection? That question relates to BitRock - a non-MSI installer technology, but the overall issue seems to be the same.
Extract from one of the links pointed to in my answer above: "...a certificate just isn't enough anymore to gain trust... SmartScreen is reputation based, not unlike the way StackOverflow works... SmartScreen trusts installers that don't cause problems. Windows machines send telemetry back to Redmond about installed programs and how much trouble they cause. If you get enough thumbs-up then SmartScreen stops blocking your installer automatically. This takes time and lots of installs to get sufficient thumbs. There is no way to find out how far along you got."
Honestly this is all news to me at this point, so do get back to us with any information you dig up yourself.
The actual dialog text you have marked above definitely relates to the Zone.Identifier
alternate data stream with a value of 3
that is added to any file that is downloaded from the Internet (see linked answer above for more details).
I was not able to mark this question as a duplicate of the previous one, since it doesn't have an accepted answer. Let's leave both question open for now? (one question is for MSI, one is for non-MSI).
...
WHERE ...
AND (@Location is null OR (Location like '%' + @Location + '%'))
AND (@Date is null OR (Date = @Date))
This way it is more obvious the parameter is not used when null.
Use textView
instead then conform with its delegate, call the textViewDidChange
method inside of that method call tableView.beginUpdates()
and tableView.endUpdates()
and don't forget to set rowHeight
and estimatedRowHeight
to UITableView.automaticDimension
.
I can't comment on midopa's excellent answer due to lack of reputation.
On a Mac I (finally) successfully installed opencv from source using the following commands:
cmake -D CMAKE_BUILD_TYPE=RELEASE
-D CMAKE_INSTALL_PREFIX=/usr/local
-D PYTHON_EXECUTABLE=/Library/Frameworks/Python.framework/Versions/3.4/bin/python3
-D PYTHON_LIBRARY=/Library/Frameworks/Python.framework//Versions/3.4/lib/libpython3.4m.dylib
-D PYTHON_INCLUDE_DIR=/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m
-D PYTHON_NUMPY_INCLUDE_DIRS=/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/numpy/core/include/numpy
-D PYTHON_PACKAGES_PATH=/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages
/relative/path/to/source/directory/
Then,
make -j8
change 8 for the number of threads your machine can handle, to speed things up
sudo make install
I added a PYTHONPATH
environment variable to my ~/.bash_profile
file so that Python could find cv2.so
:
PYTHONPATH="${PYTHONPATH}:/usr/local/lib/python3.4/site-packages”
export PYTHONPATH
[For those using PyCharm, I had to go to Preferences > Project Structure > Add Content Root, and added the path to cv2.so
's parent directory: /usr/local/lib/python3.4/site-packages
]
This command got me past errors such as:
Could NOT find PythonLibs
, by explicitly declaring the python library path
ld: can't link with a main executable for architecture x86_64
collect2: error: ld returned 1 exit status
make[2]: *** [lib/cv2.so] Error 1
make[1]: *** [modules/python2/CMakeFiles/opencv_python2.dir/all] Error 2
make: *** [all] Error 2
by explicitly pointing to the libpython3.4m.dylib
In terminal, check that it worked with:
$python3
>>> import cv2
It's all good if you don't get ImportError: No module named 'cv2'
This worked on a Macbook Pro Retina 15" 2013, Mavericks 10.9.4, Python 3.4.1 (previously installed from official download), opencv3 from source. Hope that this helps someone.
Perhaps you could try passing location into the component as a prop. Below I use ...otherProps. This is the spread operator, and is valid but unneccessary if you passed in your props explicitly it's just there as a place holder for demonstration purposes. Also, research destructuring to understand where ({ location }) came from.
import React from 'react';
import withRouter from 'react-router-dom';
const MyComponent = ({ location, ...otherProps }) => (whatever you want to render)
export withRouter(MyComponent);
You also can set the width of a audio tag by JavaScript:
audio = document.getElementById('audio-id');
audio.style.width = '200px';
Put the following code in your CSS, this works with Bootstrap 4:
.w-100 {
width: 100% !important;
height: 75vh;
}
This happens because the provisioning profile can't find the file for the certificate it is linked to.
To fix:
The error should be gone now.
.get responses are cached by default. Therefore you really need to do nothing to get the desired results.
Cava Packager is great on the Windows ecosystem.
You can also use String.valueOf((Object) nullableString)
like
switch (String.valueOf((Object) nullableString)) {
case "someCase"
//...
break;
...
case "null": // or default:
//...
break;
}
See interesting SO Q/A: Why does String.valueOf(null) throw a NullPointerException
$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);
I put them on two separate lines to make the code a little more clear.
Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z
.
I tried the methods mentioned in some other answers, but they look like workarounds to me. Using Firefox Add-on RESTclient to send HTTP POST requests with parameters is not straightforward in my opinion, at least for the version I'm currently using, 2.0.1.
Instead, try using other free open source tools, such as Apache JMeter. It is simple and straightforward (see the screenshot as below)
For Bootstrap 4.x
, you can do like this :
$('#modal').data('bs.modal')._config.backdrop = 'static';
$('#modal').data('bs.modal')._config.keyboard = false;
You can give this simple jQuery plugin (AnimateScroll) a whirl. It is quite easy to use.
1. Scroll to the top of the page:
$('body').animatescroll();
2. Scroll to an element with ID section-1
:
$('#section-1').animatescroll({easing:'easeInOutBack'});
Disclaimer: I am the author of this plugin.
you can search this file : resetroot.bat
just double click it so that your root accout will be reset and all the privileges are turned into YES
You can read JNE/Z as *
Jump if the status is "Not set" on Equal/Zero flag
"Not set" is a status when "equal/zero flag" in the CPU is set to 0 which only happens when the condition is met or equally matched.
Create uninitialized multidimensional array:
function MultiArray(a) {
if (a.length < 1) throw "Invalid array dimension";
if (a.length == 1) return Array(a[0]);
return [...Array(a[0])].map(() => MultiArray(a.slice(1)));
}
Create initialized multidimensional array:
function MultiArrayInit(a, init) {
if (a.length < 1) throw "Invalid array dimension";
if (a.length == 1) return Array(a[0]).fill(init);
return [...Array(a[0])].map(() => MultiArrayInit(a.slice(1), init));
}
Usage:
MultiArray([3,4,5]); // -> Creates an array of [3][4][5] of empty cells
MultiArrayInit([3,4,5], 1); // -> Creates an array of [3][4][5] of 1s
Just wanted to focus on the last part of the question; How source map files are created? by listing the build tools I know that can create source maps.
grunt-contrib-uglify

Using Erik's answer, as a starting point. I found a simpler solution that worked for me.
In my ng-click function I have:
var the_string = 'lifeMeaning';
if ($scope[the_string] === undefined) {
//Valid in my application for first usage
$scope[the_string] = true;
} else {
$scope[the_string] = !$scope[the_string];
}
//$scope.$apply
I've tested it with and without $scope.$apply. Works correctly without it!
You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.
$("button").click(function() {
var $btn = $(this);
$btn.button('loading');
// simulating a timeout
setTimeout(function () {
$btn.button('reset');
}, 1000);
});
Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.
Adding overflow:auto
before setting overflow-y
seems to do the trick in Google Chrome.
{
width:249px;
height:299px;
background-color:Gray;
overflow: auto;
overflow-y: scroll;
max-width:230px;
max-height:100px;
}
I did all the changes mentioned in every other answer and none worked. What did I learn? Enable and Continue exists in both the Tools > Options > Debugging menu and also in the Project settings. After I checked both, Enable and Continue worked for me.
The problem is in the line before the one that throws the warning. When you create df_2 that's where you're creating a copy of a slice of a dataframe. Instead, when you create df_2, use .copy() and you won't get that warning later on.
df_2 = df[df['B'] == 'b.2'].copy()
Calling the no-arguments super constructor is just a waste of screen space and programmer time. The compiler generates exactly the same code, whether you write it or not.
class Explicit() {
Explicit() {
super();
}
}
class Implicit {
Implicit() {
}
}
I faced the same issue recently. I found a solution that apparently works for all devices. You can't do async focus programmatically but you can switch focus to your target input when some other input is already focused. So what you need to do is create, hide, append to DOM & focus a fake input on trigger event and, when the async action completes, just call focus again on the target input. Here's an example snippet - run it on your mobile.
edit:
Here's a fiddle with the same code. Apparently you can't run attached snippets on mobiles (or I'm doing something wrong).

Take a look at this article which shows the registry keys you need to look for and provides a .NET library that will do this for you.
First, you should to determine if .NET 3.5 is installed by looking at HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5\Install, which is a DWORD value. If that value is present and set to 1, then that version of the Framework is installed.
Look at HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5\SP, which is a DWORD value which indicates the Service Pack level (where 0 is no service pack).
To be correct about things, you really need to ensure that .NET Fx 2.0 and .NET Fx 3.0 are installed first and then check to see if .NET 3.5 is installed. If all three are true, then you can check for the service pack level.
I believe that the best format for universal interoperability is not the ISO-8601 string, but rather the format used by EJSON:
{ "myDateField": { "$date" : <ms-since-epoch> } }
As described here: https://docs.meteor.com/api/ejson.html
Benefits
Conclusion
I understand that a human-readable format (ISO-8601 string) is helpful and more convenient for 80% of use cases, and indeed no-one should ever be told not to store their dates as ISO-8601 strings if that's what their applications understand, but for a universally accepted transport format which should guarantee certain values to for sure be dates, how can we allow for ambiguity and need for so much validation?
With primitives, it probably doesn't matter entirely which one you use. I say where it gets usefulness is when you want to output complex objects.
For example, if you have a class,
#include <iostream>
#include <cstdlib>
using namespace std;
class Something
{
public:
Something(int x, int y, int z) : a(x), b(y), c(z) { }
int a;
int b;
int c;
friend ostream& operator<<(ostream&, const Something&);
};
ostream& operator<<(ostream& o, const Something& s)
{
o << s.a << ", " << s.b << ", " << s.c;
return o;
}
int main(void)
{
Something s(3, 2, 1);
// output with printf
printf("%i, %i, %i\n", s.a, s.b, s.c);
// output with cout
cout << s << endl;
return 0;
}
Now the above might not seem all that great, but let's suppose you have to output this in multiple places in your code. Not only that, let's say you add a field "int d." With cout, you only have to change it in once place. However, with printf, you'd have to change it in possibly a lot of places and not only that, you have to remind yourself which ones to output.
With that said, with cout, you can reduce a lot of times spent with maintenance of your code and not only that if you re-use the object "Something" in a new application, you don't really have to worry about output.
For those like me who are brand new to this, here is code with const and an actual way to compare the byte[]'s. I got all of this code from stackoverflow but defined consts so values could be changed and also
// 24 = 192 bits
private const int SaltByteSize = 24;
private const int HashByteSize = 24;
private const int HasingIterationsCount = 10101;
public static string HashPassword(string password)
{
// http://stackoverflow.com/questions/19957176/asp-net-identity-password-hashing
byte[] salt;
byte[] buffer2;
if (password == null)
{
throw new ArgumentNullException("password");
}
using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, SaltByteSize, HasingIterationsCount))
{
salt = bytes.Salt;
buffer2 = bytes.GetBytes(HashByteSize);
}
byte[] dst = new byte[(SaltByteSize + HashByteSize) + 1];
Buffer.BlockCopy(salt, 0, dst, 1, SaltByteSize);
Buffer.BlockCopy(buffer2, 0, dst, SaltByteSize + 1, HashByteSize);
return Convert.ToBase64String(dst);
}
public static bool VerifyHashedPassword(string hashedPassword, string password)
{
byte[] _passwordHashBytes;
int _arrayLen = (SaltByteSize + HashByteSize) + 1;
if (hashedPassword == null)
{
return false;
}
if (password == null)
{
throw new ArgumentNullException("password");
}
byte[] src = Convert.FromBase64String(hashedPassword);
if ((src.Length != _arrayLen) || (src[0] != 0))
{
return false;
}
byte[] _currentSaltBytes = new byte[SaltByteSize];
Buffer.BlockCopy(src, 1, _currentSaltBytes, 0, SaltByteSize);
byte[] _currentHashBytes = new byte[HashByteSize];
Buffer.BlockCopy(src, SaltByteSize + 1, _currentHashBytes, 0, HashByteSize);
using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, _currentSaltBytes, HasingIterationsCount))
{
_passwordHashBytes = bytes.GetBytes(SaltByteSize);
}
return AreHashesEqual(_currentHashBytes, _passwordHashBytes);
}
private static bool AreHashesEqual(byte[] firstHash, byte[] secondHash)
{
int _minHashLength = firstHash.Length <= secondHash.Length ? firstHash.Length : secondHash.Length;
var xor = firstHash.Length ^ secondHash.Length;
for (int i = 0; i < _minHashLength; i++)
xor |= firstHash[i] ^ secondHash[i];
return 0 == xor;
}
In in your custom ApplicationUserManager, you set the PasswordHasher property the name of the class which contains the above code.
You might be better off using the Properties Service as you can use these as a kind of persistent global variable.
click 'file > project properties > project properties' to set a key value, or you can use
PropertiesService.getScriptProperties().setProperty('mykey', 'myvalue');
The data can be retrieved with
var myvalue = PropertiesService.getScriptProperties().getProperty('mykey');

Also, I noticed one more difference between .load and .ready. I am opening a child window and I am performing some work when child window opens. .load is called only first time when I open the window and if I don't close the window then .load will not be called again. however, .ready is called every time irrespective of close the child window or not.
Try
find . -type d
or
find . -type d -ls
OK, you’ve been told, or have found out yourself, that globals (namespace scope variables that can be accessed outside the translation unit) are Evil™. But did you know how truly Evil™ they are? Consider the program below, consisting of two files [main.cpp] and [numbers.cpp]:

In Windows 7 this compiles and links fine with both MinGW g++ 4.4.1 and Visual C++ 10.0.
Since the types don't match, the program crashes when you run it.
In-the-formal explanation: the program has Undefined Behavior (UB), and instead of crashing it can therefore just hang, or perhaps do nothing, or it can send threating e-mails to the presidents of the USA, Russia, India, China and Switzerland, and make Nasal Daemons fly out of your nose.
In-practice explanation: in main.cpp
the array is treated as a pointer, placed
at the same address as the array. For 32-bit executable this means that the first
int
value in the array, is treated as a pointer. I.e., in main.cpp
the
numbers
variable contains, or appears to contain, (int*)1
. This causes the
program to access memory down at very bottom of the address space, which is
conventionally reserved and trap-causing. Result: you get a crash.
The compilers are fully within their rights to not diagnose this error, because C++11 §3.5/10 says, about the requirement of compatible types for the declarations,
[N3290 §3.5/10]
A violation of this rule on type identity does not require a diagnostic.
The same paragraph details the variation that is allowed:
… declarations for an array object can specify array types that differ by the presence or absence of a major array bound (8.3.4).
This allowed variation does not include declaring a name as an array in one translation unit, and as a pointer in another translation unit.
memset
& friends).Not written yet
With deep C experience it’s natural to write …
#define N_ITEMS( array ) (sizeof( array )/sizeof( array[0] ))
Since an array
decays to pointer to first element where needed, the
expression sizeof(a)/sizeof(a[0])
can also be written as
sizeof(a)/sizeof(*a)
. It means the same, and no matter how it’s
written it is the C idiom for finding the number elements of array.
Main pitfall: the C idiom is not typesafe. For example, the code …
#include <stdio.h>
#define N_ITEMS( array ) (sizeof( array )/sizeof( *array ))
void display( int const a[7] )
{
int const n = N_ITEMS( a ); // Oops.
printf( "%d elements.\n", n );
}
int main()
{
int const moohaha[] = {1, 2, 3, 4, 5, 6, 7};
printf( "%d elements, calling display...\n", N_ITEMS( moohaha ) );
display( moohaha );
}
passes a pointer to N_ITEMS
, and therefore most likely produces a wrong
result. Compiled as a 32-bit executable in Windows 7 it produces …
7 elements, calling display...
1 elements.
int const a[7]
to just int const a[]
.int const a[]
to int const* a
.N_ITEMS
is therefore invoked with a pointer.sizeof(array)
(size of a pointer) is then 4.sizeof(*array)
is equivalent to sizeof(int)
, which for a 32-bit executable is also 4.In order to detect this error at run time you can do …
#include <assert.h>
#include <typeinfo>
#define N_ITEMS( array ) ( \
assert(( \
"N_ITEMS requires an actual array as argument", \
typeid( array ) != typeid( &*array ) \
)), \
sizeof( array )/sizeof( *array ) \
)
7 elements, calling display...
Assertion failed: ( "N_ITEMS requires an actual array as argument", typeid( a ) != typeid( &*a ) ), file runtime_detect ion.cpp, line 16This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
The runtime error detection is better than no detection, but it wastes a little processor time, and perhaps much more programmer time. Better with detection at compile time! And if you're happy to not support arrays of local types with C++98, then you can do that:
#include <stddef.h>
typedef ptrdiff_t Size;
template< class Type, Size n >
Size n_items( Type (&)[n] ) { return n; }
#define N_ITEMS( array ) n_items( array )
Compiling this definition substituted into the first complete program, with g++, I got …
M:\count> g++ compile_time_detection.cpp
compile_time_detection.cpp: In function 'void display(const int*)':
compile_time_detection.cpp:14: error: no matching function for call to 'n_items(const int*&)'M:\count> _
How it works: the array is passed by reference to n_items
, and so it does
not decay to pointer to first element, and the function can just return the
number of elements specified by the type.
With C++11 you can use this also for arrays of local type, and it's the type safe C++ idiom for finding the number of elements of an array.
constexpr
array size function.With C++11 and later it's natural, but as you'll see dangerous!, to replace the C++03 function
typedef ptrdiff_t Size;
template< class Type, Size n >
Size n_items( Type (&)[n] ) { return n; }
with
using Size = ptrdiff_t;
template< class Type, Size n >
constexpr auto n_items( Type (&)[n] ) -> Size { return n; }
where the significant change is the use of constexpr
, which allows
this function to produce a compile time constant.
For example, in contrast to the C++03 function, such a compile time constant can be used to declare an array of the same size as another:
// Example 1
void foo()
{
int const x[] = {3, 1, 4, 1, 5, 9, 2, 6, 5, 4};
constexpr Size n = n_items( x );
int y[n] = {};
// Using y here.
}
But consider this code using the constexpr
version:
// Example 2
template< class Collection >
void foo( Collection const& c )
{
constexpr int n = n_items( c ); // Not in C++14!
// Use c here
}
auto main() -> int
{
int x[42];
foo( x );
}
The pitfall: as of July 2015 the above compiles with MinGW-64 5.1.0 with
-pedantic-errors
, and,
testing with the online compilers at gcc.godbolt.org/, also with clang 3.0
and clang 3.2, but not with clang 3.3, 3.4.1, 3.5.0, 3.5.1, 3.6 (rc1) or
3.7 (experimental). And important for the Windows platform, it does not compile
with Visual C++ 2015. The reason is a C++11/C++14 statement about use of
references in constexpr
expressions:
A conditional-expression
e
is a core constant expression unless the evaluation ofe
, following the rules of the abstract machine (1.9), would evaluate one of the following expressions:
?
- an id-expression that refers to a variable or data member of reference type unless the reference has a preceding initialization and either
- it is initialized with a constant expression or
- it is a non-static data member of an object whose lifetime began within the evaluation of e;
One can always write the more verbose
// Example 3 -- limited
using Size = ptrdiff_t;
template< class Collection >
void foo( Collection const& c )
{
constexpr Size n = std::extent< decltype( c ) >::value;
// Use c here
}
… but this fails when Collection
is not a raw array.
To deal with collections that can be non-arrays one needs the overloadability of an
n_items
function, but also, for compile time use one needs a compile time
representation of the array size. And the classic C++03 solution, which works fine
also in C++11 and C++14, is to let the function report its result not as a value
but via its function result type. For example like this:
// Example 4 - OK (not ideal, but portable and safe)
#include <array>
#include <stddef.h>
using Size = ptrdiff_t;
template< Size n >
struct Size_carrier
{
char sizer[n];
};
template< class Type, Size n >
auto static_n_items( Type (&)[n] )
-> Size_carrier<n>;
// No implementation, is used only at compile time.
template< class Type, size_t n > // size_t for g++
auto static_n_items( std::array<Type, n> const& )
-> Size_carrier<n>;
// No implementation, is used only at compile time.
#define STATIC_N_ITEMS( c ) \
static_cast<Size>( sizeof( static_n_items( c ).sizer ) )
template< class Collection >
void foo( Collection const& c )
{
constexpr Size n = STATIC_N_ITEMS( c );
// Use c here
(void) c;
}
auto main() -> int
{
int x[42];
std::array<int, 43> y;
foo( x );
foo( y );
}
About the choice of return type for static_n_items
: this code doesn't use std::integral_constant
because with std::integral_constant
the result is represented
directly as a constexpr
value, reintroducing the original problem. Instead
of a Size_carrier
class one can let the function directly return a
reference to an array. However, not everybody is familiar with that syntax.
About the naming: part of this solution to the constexpr
-invalid-due-to-reference
problem is to make the choice of compile time constant explicit.
Hopefully the oops-there-was-a-reference-involved-in-your-constexpr
issue will be fixed with
C++17, but until then a macro like the STATIC_N_ITEMS
above yields portability,
e.g. to the clang and Visual C++ compilers, retaining type safety.
Related: macros do not respect scopes, so to avoid name collisions it can be a
good idea to use a name prefix, e.g. MYLIB_STATIC_N_ITEMS
.
I've seen a lot of examples that use "break" but none that use "continue".
It still would require a flag of some sort in the inner loop:
while( some_condition )
{
// outer loop stuff
...
bool get_out = false;
for(...)
{
// inner loop stuff
...
get_out = true;
break;
}
if( get_out )
{
some_condition=false;
continue;
}
// more out loop stuff
...
}

Enter the following command in the directory you want to modify the right:
for example the directory: /var/www/html
sudo setfacl -m g:username:rwx . #-> for file
sudo setfacl -d -m g:username: rwx . #-> for directory
This will solve the problem.
Replace username with your username.
Your own answer technically wasn't incorrect, but you got the index wrong since indexes start at 0, not 1. That's why you got the wrong selection.
document.getElementById('personlist').getElementsByTagName('option')[**10**].selected = 'selected';
Also, your answer is actually a good one for cases where the tags aren't entirely English or numeric.
If they use, for example, Asian characters, the other solutions telling you to use .value() may not always function and will just not do anything. Selecting by tag is a good way to ignore the actual text and select by the element itself.
This answer is similar to Alexander Ukhov's answer, except that it uses touch events rather than click events. Those event allow the parent to display the proper pressed states (e.g., ripple effect). This answer is also in Kotlin instead of Java.

A cleaned up and reusable solution using pymongo:
from pymongo import MongoClient
from bson import Code
def get_keys(db, collection):
client = MongoClient()
db = client[db]
map = Code("function() { for (var key in this) { emit(key, null); } }")
reduce = Code("function(key, stuff) { return null; }")
result = db[collection].map_reduce(map, reduce, "myresults")
return result.distinct('_id')
Usage:
get_keys('dbname', 'collection')
>> ['key1', 'key2', ... ]
If you really want to create them on the fly you can assign to the dict that is returned by either globals()
or locals()
depending on what namespace you want to create them in:
globals()['somevar'] = 'someval'
print somevar # prints 'someval'
But I wouldn't recommend doing that. In general, avoid global variables. Using locals()
often just obscures what you are really doing. Instead, create your own dict and assign to it.
mydict = {}
mydict['somevar'] = 'someval'
print mydict['somevar']

Combining answers https://stackoverflow.com/a/8462/1037948 (declaration via bit-shifting) and https://stackoverflow.com/a/9117/1037948 (using combinations in declaration) you can bit-shift previous values rather than using numbers. Not necessarily recommending it, but just pointing out you can.
Rather than:
[Flags]
public enum Options : byte
{
None = 0,
One = 1 << 0, // 1
Two = 1 << 1, // 2
Three = 1 << 2, // 4
Four = 1 << 3, // 8
// combinations
OneAndTwo = One | Two,
OneTwoAndThree = One | Two | Three,
}
You can declare
[Flags]
public enum Options : byte
{
None = 0,
One = 1 << 0, // 1
// now that value 1 is available, start shifting from there
Two = One << 1, // 2
Three = Two << 1, // 4
Four = Three << 1, // 8
// same combinations
OneAndTwo = One | Two,
OneTwoAndThree = One | Two | Three,
}
Confirming with LinqPad:
foreach(var e in Enum.GetValues(typeof(Options))) {
string.Format("{0} = {1}", e.ToString(), (byte)e).Dump();
}
Results in:
None = 0
One = 1
Two = 2
OneAndTwo = 3
Three = 4
OneTwoAndThree = 7
Four = 8
I have a previously-working code that throws this error now. No issue on password. No need to convert message to base64 either. Turns out, i need to do the following:
Working code

};
client.Send("[email protected]", emailTo, subject, body);
}
Turning off 2-factor authentication
Set "Allow less secure apps" to ON (same page, need to scroll to bottom)
You can just do this:
git remote add origin ssh://user@host:1234/srv/git/example

Kotlin supports type aliases https://kotlinlang.org/docs/reference/type-aliases.html. You can rename types and function types.
Use Linq Join operator:
var q = from d in Dealer
join dc in DealerConact on d.DealerID equals dc.DealerID
select dc;
string appPath = System.IO.Path.GetDirectoryName(Application.ExecutablePath);
Returns the directory information for the specified path string.
From Application.ExecutablePath
Gets the path for the executable file that started the application, including the executable name.
Alternatively, if using javax.net.ssl.trustStore for specifying the location of your truststore does not work ( as it did in my case for two way authentication ), you can also use SSLContextBuilder as shown in the example below. This example also includes how to create a httpclient as well to show how the SSL builder would work.
SSLContextBuilder sslcontextbuilder = SSLContexts.custom();
sslcontextbuilder.loadTrustMaterial(
new File("C:\\path to\\truststore.jks"), //path to jks file
"password".toCharArray(), //enters in the truststore password for use
new TrustSelfSignedStrategy() //will trust own CA and all self-signed certs
);
SSLContext sslcontext = sslcontextbuilder.build(); //load trust store
SSLConnectionSocketFactory sslsockfac = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,SSLConnectionSocketFactory.getDefaultHostnameVerifier());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsockfac).build(); //sets up a httpclient for use with ssl socket factory
try {
HttpGet httpget = new HttpGet("https://localhost:8443"); //I had a tomcat server running on localhost which required the client to have their trust cert
System.out.println("Executing request " + httpget.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httpget);
try {
HttpEntity entity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
EntityUtils.consume(entity);
} finally {
response.close();
}
} finally {
httpclient.close();
}
You can download manually by parsing the XMLs that you see in Android SDK Manager log.
Currently the XMLs are addon_list and repository. These xmls can change over a course of time.
It has the location of the SDKs, you can browse to the link and download directly via browser. These files has to be placed under proper folder, example the files of google APIs has to be placed under add-ons
, if you don't know where the files has to go.

In your view, you have to cast it back to the original type. Without the cast, it's just an object.
<td>@((ViewBag.data as ICollection<Person>).First().FirstName)</td>
ViewBag is a C# 4 dynamic type. Entities returned from it are also dynamic unless cast. However, extension methods like .First() and all the other Linq ones do not work with dynamics.
Edit - to address the comment:
If you want to display the whole list, it's as simple as this:
<ul>
@foreach (var person in ViewBag.data)
{
<li>@person.FirstName</li>
}
</ul>
Extension methods like .First() won't work, but this will.
I've ended up here looking for "how to mock a function based on input arguments" and I finally solved this creating a simple aux function:
def mock_responses(responses, default_response=None):
return lambda input: responses[input] if input in responses else default_response
Now:
my_mock.foo.side_effect = mock_responses(
{
'x': 42,
'y': [1,2,3]
})
my_mock.goo.side_effect = mock_responses(
{
'hello': 'world'
},
default_response='hi')
...
my_mock.foo('x') # => 42
my_mock.foo('y') # => [1,2,3]
my_mock.foo('unknown') # => None
my_mock.goo('hello') # => 'world'
my_mock.goo('ey') # => 'hi'
Hope this will help someone!

Another approach would be to leverage the INSERT ALL
syntax from oracle,
INSERT ALL
INTO table1(email, campaign_id) VALUES (email, campaign_id)
WITH source_data AS
(SELECT '[email protected]' email,100 campaign_id
FROM dual
UNION ALL
SELECT '[email protected]' email,200 campaign_id
FROM dual)
SELECT email
,campaign_id
FROM source_data src
WHERE NOT EXISTS (SELECT 1
FROM table1 dest
WHERE src.email = dest.email
AND src.campaign_id = dest.campaign_id);
INSERT ALL
also allow us to perform a conditional insert into multiple tables based on a sub query as source.
There are some really clean and nice examples are there to refer.
Looks like you have an open git commit

going on, and an editor is still open editing the commit message.
Two choices:
.swp
file (if you're sure the other git session has gone away).Clarification from comments:
.swp
is being used by entering the command :sw
within the editing session, but generally it's a hidden file in the same directory as the file you are using, with a .swp
file suffix (i.e. ~/myfile.txt
would be ~/.myfile.txt.swp
).You don't need to replace it with anything. The setting magic_quotes_runtime
is removed in PHP6 so the function call is unneeded. If you want to maintain backwards compatibility it may be wise to wrap it in a if statement checking phpversion using version_compare

Dates in VBA are just floating point numbers, where the integer part represents the date and the fraction part represents the time. So in addition to using the Date

The suggested technique above in Dave's answer is certainly a good design practice, and yes ultimately the required permission must be set in the AndroidManifest.xml file to access the external storage.
However, the Mono-esque way to add most (if not all, not sure) "manifest options" is through the attributes of the class implementing the activity (or service).
The Visual Studio Mono plugin automatically generates the manifest, so its best not to manually tamper with it (I'm sure there are cases where there is no other option).
For example:
[Activity(Label="MonoDroid App", MainLauncher=true, Permission="android.permission.WRITE_EXTERNAL_STORAGE")]
public class MonoActivity : Activity
{
protected override void OnCreate(Bundle bindle)
{
base.OnCreate(bindle);
}
}
If you don't mind getting your hands dirty, it isn't that difficult to write an RTF to HTML converter.
Writing a general purpose RTF->HTML converter would be somewhat complicated because you would need to deal with hundreds of RTF verbs. However, in your case you are only dealing with those verbs used specifically by Crystal Reports. I'll bet the standard RTF coding generated by Crystal doesn't vary much from report to report.
I wrote an RTF to HTML converter in C++, but it only deals with basic formatting like fonts, paragraph alignments, etc. My translator basically strips out any specialized formatting that it isn't prepared to deal with. It took about 400 lines of C++. It basically scans the text for RTF tags and replaces them with equivalent HTML tags. RTF tags that aren't in my list are simply stripped out. A regex function is really helpful when writing such a converter.
When you're serving an .ico file to be used as a favicon, it doesn't matter. All major browsers recognize both mime types correctly. So you could put:
<!-- IE -->
<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
<!-- other browsers -->
<link rel="icon" type="image/x-icon" href="favicon.ico" />
or the same with image/vnd.microsoft.icon
, and it will work with all browsers.
Note: There is no IANA specification for the MIME-type image/x-icon
, so it does appear that it is a little more unofficial than image/vnd.microsoft.icon
.
The only case in which there is a difference is if you were trying to use an .ico file in an <img>
tag (which is pretty unusual).
Based on previous testing, some browsers would only display .ico files as images when they were served with the MIME-type image/x-icon
. More recent tests show: Chromium, Firefox and Edge are fine with both content types, IE11 is not. If you can, just avoid using ico
files as images, use png
.

public int hashCode() {
int h = hash;
if (h == 0) {
int off = offset;
char val[] = value;
int len = count;
for (int i = 0; i < len; i++) {
h = 31*h + val[off++];
}
hash = h;
}
return h;
}
Apache Harmony
public int hashCode() {
if (hashCode == 0) {
int hash = 0, multiplier = 1;
for (int i = offset + count - 1; i >= offset; i--) {
hash += value[i] * multiplier;
int shifted = multiplier << 5;
multiplier = shifted - multiplier;
}
hashCode = hash;
}
return hashCode;
}
Feel free to check it yourself...
If your hardware is 32-bit only, then no. If you have 64 bit hardware and a 32-bit operating system, then maybe. See Hardware and Firmware Requirements for 64-Bit Guest Operating Systems for details. It has nothing to do with one vs. multiple processors.
I tried the above solution but I found it unsuitable for large amounts of data. I then discovered the stream feature:
MongoClient.connect("...", function(err, db){
var c = db.collection('yourCollection');
var s = c.find({/* your query */}).stream();
s.on('data', function(doc){
c.update({_id: doc._id}, {$set: {name : doc.firstName + ' ' + doc.lastName}}, function(err, result) { /* result == true? */} }
});
s.on('end', function(){
// stream can end before all your updates do if you have a lot
})
})
Google Fonts uses Web Open Font Format (WOFF), which is good, because it's the recommended font format by the W3C.
IE versions older than IE9 don't support Web Open Font Format (WOFF) because it didn't exist back then. To support < IE9, you need to serve your font in Embedded Open Type (EOT). To do this you will need to write your own @font-face css tag instead of using the embed script from Google. Also you need to convert the original WOFF file to EOT.
You can convert your WOFF to EOT over here by first converting it to TTF and then to EOT: http://convertfonts.com/
Then you can serve the EOT font like this:
@font-face {
font-family: 'MyFont';
src: url('myfont.eot');
}
Now it works in < IE9. However, modern browsers don't support EOT anymore, so now your fonts won't work in modern browsers. So you need to specify them both. The src property supports this by comma seperating the font urls and specefying the type:
src: url('myfont.woff') format('woff'),
url('myfont.eot') format('embedded-opentype');
However, < IE9 doesn't understand this, it just graps the text between the first quote and the last quote, so it will actually get:
myfont.woff') format('woff'),
url('myfont.eot') format('embedded-opentype
as the URL to the font. We can fix this by first specifying a src with only one url which is the EOT format, then specifying a second src property that's meant for the modern browsers and < IE9 will not understand. Because < IE9 will not understand it it will ignore the tag so the EOT will still be working. The modern browsers will use the last specified font they support, so probably WOFF.
src: url('myfont.eot');
src: url('myfont.woff') format('woff');
So only because in the second src property you specify the format('woff')
, < IE9 won't understand it (or actually it just can't find the font at the url myfont.woff') format('woff
) and will keep using the first specified one (eot).
So now you got your Google Webfonts working for < IE9 and modern browsers!
For more information about different font type and browser support, read this perfect article by Alex Tatiyants: http://tatiyants.com/how-to-get-ie8-to-support-html5-tags-and-web-fonts/
Another one solution can be used for class components - just override default MUI Theme properties with MuiThemeProvider. This will give more flexibility in comparison with other methods - you can use more than one MuiThemeProvider inside your parent component.
simple steps:
please, check this doc for more details: https://material-ui.com/customization/theming/
import React from 'react';
import PropTypes from 'prop-types';
import Button from '@material-ui/core/Button';
import { MuiThemeProvider } from '@material-ui/core/styles';
import { createMuiTheme } from '@material-ui/core/styles';
const InputTheme = createMuiTheme({
overrides: {
root: {
background: 'linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)',
border: 0,
borderRadius: 3,
boxShadow: '0 3px 5px 2px rgba(255, 105, 135, .3)',
color: 'white',
height: 48,
padding: '0 30px',
},
}
});
class HigherOrderComponent extends React.Component {
render(){
const { classes } = this.props;
return (
<MuiThemeProvider theme={InputTheme}>
<Button className={classes.root}>Higher-order component</Button>
</MuiThemeProvider>
);
}
}
HigherOrderComponent.propTypes = {
classes: PropTypes.object.isRequired,
};
export default HigherOrderComponent;

I have the same problem. I try to present view controller just after dismissing.
[self dismissModalViewControllerAnimated:YES];
When I try to do it without animation it works perfectly so the problem is that controller is still alive. I think that the best solution is to use dismissViewControllerAnimated:completion:

wrap your entire code block in this:
//<![CDATA[

also make sure to specify the type of script to be text/javascript
try that and let me know how it goes
In my particular case I had a config file generated and cached into the bootstrap/cache/
directory so my steps where:

There is another method for calculate age is
See below table
FirstName LastName DOB
sai krishnan 1991-11-04
Harish S A 1998-10-11
For finding age,you can calculate through month
Select datediff(MONTH,DOB,getdate())/12 as dates from [Organization].[Employee]
Result will be
firstname dates
sai 27
Harish 20
public static T Runner<T>(Func<T> funcToRun)
{
//Do stuff before running function as normal
return funcToRun();
}
Usage:
var ReturnValue = Runner(() => GetUser(99));
If you set numberOfLines
to 0 (and the label to word wrap), the label will automatically wrap and use as many of lines as needed.
If you're editing a UILabel
in IB, you can enter multiple lines of text by pressing option+return to get a line break - return alone will finish editing.
in the manifest:
<activity android:name=".activity.MainActivity"
android:screenOrientation="portrait"
tools:ignore="LockedOrientationActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
or : in the MainActivity
@SuppressLint("SourceLockedOrientationActivity")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
Just dont put "\bin
" end of the path.
JAVA_HOME
should be with value C:\Program Files(x86)\Java\jdk1.7.0_51
The break
keyword does exactly that. Here is a contrived example:
public static void main(String[] args) {
int i = 0;
while (i++ < 10) {
if (i == 5) break;
}
System.out.println(i); //prints 5
}
If you were actually using nested loops, you would be able to use labels.
Thanks @BIJAY_JHA and @Manaus. I used the Kotlin version to call my signIn() method that lives in the Activity and that I'm calling from a Fragment. I'm using Navigation Architecture in Android so the Listener interface pattern isn't in the Fragment:
(activity as MainActivity).signIn()
If you want to only update on rows that are not currently uppercase (instead of all rows), you'd need to identify the difference using COLLATE
like this:
UPDATE MyTable
SET MyColumn = UPPER(MyColumn)
WHERE MyColumn != UPPER(MyColumn) COLLATE Latin1_General_CS_AS
Cases sensitivity is based on your collation settings, and is typically case insensitive by default.
Collation can be set at the Server, Database, Column, or Query Level:
-- Server
SELECT SERVERPROPERTY('COLLATION')
-- Database
SELECT name, collation_name FROM sys.databases
-- Column
SELECT COLUMN_NAME, COLLATION_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE CHARACTER_SET_NAME IS NOT NULL
Collation Names specify how a string should be encoded and read, for example:
Latin1_General_CI_AS
? Case InsensitiveLatin1_General_CS_AS
? Case SensitiveIf your count(distinct(x))
is significantly slower than count(x)
then you can speed up this query by maintaining x value counts in different table, for example table_name_x_counts (x integer not null, x_count int not null)
, using triggers. But your write performance will suffer and if you update multiple x
values in single transaction then you'd need to do this in some explicit order to avoid possible deadlock.
You are getting AttributeError
because you're calling groups
on None
, which hasn't any methods.
regex.search
returning None
means the regex couldn't find anything matching the pattern from supplied string.
when using regex, it is nice to check whether a match has been made:
Result = re.search(SearchStr, htmlString)
if Result:
print Result.groups()
I found the answer. IE stores passwords in two different locations based on the password type:
%APPDATA%\Microsoft\Credentials
, in encrypted filesHKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2
, encrypted with the urlFrom a very good page on NirSoft.com:
Starting from version 7.0 of Internet Explorer, Microsoft completely changed the way that passwords are saved. In previous versions (4.0 - 6.0), all passwords were saved in a special location in the Registry known as the "Protected Storage". In version 7.0 of Internet Explorer, passwords are saved in different locations, depending on the type of password. Each type of passwords has some limitations in password recovery:
AutoComplete Passwords: These passwords are saved in the following location in the Registry:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2
The passwords are encrypted with the URL of the Web sites that asked for the passwords, and thus they can only be recovered if the URLs are stored in the history file. If you clear the history file, IE PassView won't be able to recover the passwords until you visit again the Web sites that asked for the passwords. Alternatively, you can add a list of URLs of Web sites that requires user name/password into the Web sites file (see below).HTTP Authentication Passwords: These passwords are stored in the Credentials file under
Documents and Settings\Application Data\Microsoft\Credentials
, together with login passwords of LAN computers and other passwords. Due to security limitations, IE PassView can recover these passwords only if you have administrator rights.
In my particular case it answers the question of where; and I decided that I don't want to duplicate that. I'll continue to use CredRead
/CredWrite
, where the user can manage their passwords from within an established UI system in Windows.
Sleep meaning that thread is do nothing. Time is too large beacuse anthor thread query,but not disconnect server, default wait_timeout=28800;so you can set values smaller,eg 10. also you can kill the thread.
Yes, it is important if your item will be used as a key in a dictionary, or HashSet<T>
, etc - since this is used (in the absence of a custom IEqualityComparer<T>
) to group items into buckets. If the hash-code for two items does not match, they may never be considered equal (Equals will simply never be called).
The GetHashCode() method should reflect the Equals
logic; the rules are:
Equals(...) == true
) then they must return the same value for GetHashCode()
GetHashCode()
is equal, it is not necessary for them to be the same; this is a collision, and Equals
will be called to see if it is a real equality or not.In this case, it looks like "return FooId;
" is a suitable GetHashCode()
implementation. If you are testing multiple properties, it is common to combine them using code like below, to reduce diagonal collisions (i.e. so that new Foo(3,5)
has a different hash-code to new Foo(5,3)
):
unchecked // only needed if you're compiling with arithmetic checks enabled
{ // (the default compiler behaviour is *disabled*, so most folks won't need this)
int hash = 13;
hash = (hash * 7) + field1.GetHashCode();
hash = (hash * 7) + field2.GetHashCode();
...
return hash;
}
Oh - for convenience, you might also consider providing ==
and !=
operators when overriding Equals
and GetHashCode
.
A demonstration of what happens when you get this wrong is here.
I faced this issue on Node 10.X version. below is my working code.
const https = require('https');

var optionspost = {

}
};
let reqPost = https.request(optionspost, function(res) {
console.log("statusCode: ", res.statusCode);
res.on('data', function (chunk) {
body += chunk;
});
res.on('end', function () {
console.log("Result", body.toString());
context.succeed("Sucess")
});
res.on('error', function () {
console.log("Result Error", body.toString());
context.done(null, 'FAILURE');
});
});
reqPost.write(jsonObject);
reqPost.end();
};
Software & Database is usually not in the Standard edition of Visio, only the Pro version.
Try looking here for some templates that will work in standard edition
regarding AlexB's post:
\' Apostrophe or single quote

This is basically CMS's answer without the reliance on a particular language setting. And since we're shooting for generic, that means it should work for all @@datefirst
settings as well.
datediff(day, <start>, <end>) + 1 - datediff(week, <start>, <end>) * 2
/* if start is a Sunday, adjust by -1 */
+ case when datepart(weekday, <start>) = 8 - @@datefirst then -1 else 0 end
/* if end is a Saturday, adjust by -1 */
+ case when datepart(weekday, <end>) = (13 - @@datefirst) % 7 + 1 then -1 else 0 end
datediff(week, ...)
always uses a Saturday-to-Sunday boundary for weeks, so that expression is deterministic and doesn't need to be modified (as long as our definition of weekdays is consistently Monday through Friday.) Day numbering does vary according to the @@datefirst
setting and the modified calculations handle this correction with the small complication of some modular arithmetic.
A cleaner way to deal with the Saturday/Sunday thing is to translate the dates prior to extracting a day of week value. After shifting, the values will be back in line with a fixed (and probably more familiar) numbering that starts with 1 on Sunday and ends with 7 on Saturday.
datediff(day, <start>, <end>) + 1 - datediff(week, <start>, <end>) * 2
+ case when datepart(weekday, dateadd(day, @@datefirst, <start>)) = 1 then -1 else 0 end
+ case when datepart(weekday, dateadd(day, @@datefirst, <end>)) = 7 then -1 else 0 end
I've tracked this form of the solution back at least as far as 2002 and an Itzik Ben-Gan article. (https://technet.microsoft.com/en-us/library/aa175781(v=sql.80).aspx) Though it needed a small tweak since newer date
types don't allow date arithmetic, it is otherwise identical.
EDIT:
I added back the +1
that had somehow been left off. It's also worth noting that this method always counts the start and end days. It also assumes that the end date is on or after the start date.
The registry path for Visual Studio 2008 is the same, but with 9.0 as the version number:

if your conditionals are like that (matching a single value), a simple more elegant way would be:
$results = User::where([
'this' => value,
'that' => value,
'this_too' => value,
...
])
->get();
but if you need to OR the clauses then make sure for each orWhere() clause you repeat the must meet conditionals.
$player = Player::where([
'name' => $name,
'team_id' => $team_id
])
->orWhere([
['nickname', $nickname],
['team_id', $team_id]
])

Solution is to change Delimiter.
Content of the csv file -> Note .. Also space and , in value
Values are 6 Dutch word aap,noot,mies,Piet, Gijs, Jan
Col1;Col2;Col3
a,ap;noo,t;mi es
P,iet;G ,ijs;Ja ,n
$csv = Import-Csv C:\TejaCopy.csv -Delimiter ';'
Answer:
Write-Host $csv
@{Col1=a,ap; Col2=noo,t; Col3=mi es} @{Col1=P,iet; Col2=G ,ijs; Col3=Ja ,n}
It is possible to read a CSV file and use other Delimiter to separate each column.
It worked for my script :-)
you can use this:
try {
Intent followIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://facewebmodal/f?href=" +
"https://www.facebook.com/app_scoped_user_id/"+scoped user id+"/"));
activity.startActivity(followIntent);
} catch (Exception e) {
activity.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + user name)));
String errorMessage = (e.getMessage() == null) ? "Message is empty" : e.getMessage();
}
attention: you can get scoped user id from "link" permission facebook api

To add to Phimueme's answer above, if your string is always two characters, then you can build a 16-bit int out of the two 8-bit characters - and switch on that (to avoid nested switch/case statements).
resize()
not only allocates memory, it also creates as many instances as the desired size which you pass to resize()
as argument. But reserve()
only allocates memory, it doesn't create instances. That is,
std::vector<int> v1;
v1.resize(1000); //allocation + instance creation
cout <<(v1.size() == 1000)<< endl; //prints 1
cout <<(v1.capacity()==1000)<< endl; //prints 1
std::vector<int> v2;
v2.reserve(1000); //only allocation
cout <<(v2.size() == 1000)<< endl; //prints 0
cout <<(v2.capacity()==1000)<< endl; //prints 1
Output (online demo):
1
1
0
1
So resize()
may not be desirable, if you don't want the default-created objects. It will be slow as well. Besides, if you push_back()
new elements to it, the size()
of the vector will further increase by allocating new memory (which also means moving the existing elements to the newly allocated memory space). If you have used reserve()
at the start to ensure there is already enough allocated memory, the size()
of the vector will increase when you push_back()
to it, but it will not allocate new memory again until it runs out of the space you reserved for it.
It is always best practice to do something like this.
var $request;
if ($request != null){
$request.abort();
$request = null;
}
$request = $.ajax({
type : "POST", //TODO: Must be changed to POST
url : "yourfile.php",
data : "data"
}).done(function(msg) {
alert(msg);
});
But it is much better if you check an if statement to check whether the ajax request is null or not.
This worked in the following way in my case and working fine
$("#compositeTable").find("tr:gt(1)").remove();
The following uses a regular expression to test the length. testex ensures you don't have 16 or greater consecutive non-comma characters. If it passes the test, then it proceeds to split the string. counting the commas is as simple as counting the tokens minus one.
var mainStr = "str1,str2,str3,str4";
var testregex = /([^,]{16,})/g;
if (testregex.test(mainStr)) {
alert("values must be separated by commas and each may not exceed 15 characters");
} else {
var strs = mainStr.split(',');
alert("mainStr contains " + strs.length + " substrings separated by commas.");
alert("mainStr contains " + (strs.length-1) + " commas.");
}
Actually without PDB files and symbolic information they have it would be impossible to create a successful crash report (memory dump files) and Microsoft would not have the complete picture what caused the problem.
And so having PDB improves crash reporting.
You can do either:
$("h1").css("background-color", "yellow");
Or:
$("h1").css({backgroundColor: "yellow"});
In Eclipse it is very easy to point Tomcat to a new JVM (in this example JRE6). My problem was I couldn't find where to do it. Here is the trick:
That's all. Interesting, only steps 7-10 seem to matter, and they will change the JRE used on all servers you have previously defined to use TOMCAT v7.0. The rest of the steps are just because I can't find any other way to get to the screen except by defining a new server. Does anyone else know an easier way?
TGrid is another option that people don't usually find in a google search. If the other grids you find don't suit your needs, you can give it a try, its free
emplace_back
shouldn't take an argument of type vector::value_type
, but instead variadic arguments that are forwarded to the constructor of the appended item.
template <class... Args> void emplace_back(Args&&... args);
It is possible to pass a value_type
which will be forwarded to the copy constructor.
Because it forwards the arguments, this means that if you don't have rvalue, this still means that the container will store a "copied" copy, not a moved copy.
std::vector<std::string> vec;
vec.emplace_back(std::string("Hello")); // moves
std::string s;
vec.emplace_back(s); //copies
But the above should be identical to what push_back
does. It is probably rather meant for use cases like:
std::vector<std::pair<std::string, std::string> > vec;
vec.emplace_back(std::string("Hello"), std::string("world"));
// should end up invoking this constructor:
//template<class U, class V> pair(U&& x, V&& y);
//without making any copies of the strings
There are a few ways to do this.
The first is the most widely used. It works on all major browsers.
input[readonly] {
background-color: #dddddd;
}
While the one above will select all inputs with readonly
attached, this one below will select only what you desire. Make sure to replace demo
with whatever input type you want.
input[type="demo"]:read-only {
background-color: #dddddd;
}
This is an alternate to the first, but it's not used a whole lot:
input:read-only {
background-color: #dddddd;
}
The :read-only
selector is supported in Chrome, Opera, and Safari. Firefox uses :-moz-read-only
. IE doesn't support the :read-only
selector.
You can also use input[readonly="readonly"]
, but this is pretty much the same as input[readonly]
, from my experience.
This works for me:
#doit{
background-image: url('images/pic.png');
background-repeat: no-repeat;
background-position: center;
}

You can escape the "space" char by putting a \ right before it.
One main difference is the Local
part of LocalDateTime
. If you live in Germany and create a LocalDateTime
instance and someone else lives in USA and creates another instance at the very same moment (provided the clocks are properly set) - the value of those objects would actually be different. This does not apply to Instant
, which is calculated independently from time zone.
LocalDateTime
stores date and time without timezone, but it's initial value is timezone dependent. Instant
's is not.
Moreover, LocalDateTime
provides methods for manipulating date components like days, hours, months. An Instant
does not.
apart from the nanosecond precision advantage of Instant and the time-zone part of LocalDateTime
Both classes have the same precision. LocalDateTime
does not store timezone. Read javadocs thoroughly, because you may make a big mistake with such invalid assumptions: Instant and LocalDateTime.
"A singleton with parameters is not a singleton" statement is not completely correct. We need to analyze this from the application perspective rather than from the code perspective.
We build singleton class to create a single instance of an object in one application run. By having a constructor with parameter, you can build flexibility into your code to change some attributes of your singleton object every time you run you application. This is not a violation of Singleton pattern. It looks like a violation if you see this from code perspective.
Design Patterns are there to help us write flexible and extendable code, not to hinder us writing good code.
You want to apply a custom formatting rule. The "Applies to" field should be your entire row (If you want to format row 5, put in =$5:$5
. The custom formula should be =IF($B$5="X", TRUE, FALSE)
, shown in the example below.
This worked for me. Repeatedly calls a function updating the graph every time.
import matplotlib.pyplot as plt
import matplotlib.animation as anim
def plot_cont(fun, xmax):
y = []
fig = plt.figure()
ax = fig.add_subplot(1,1,1)
def update(i):
yi = fun()
y.append(yi)
x = range(len(y))
ax.clear()
ax.plot(x, y)
print i, ': ', yi
a = anim.FuncAnimation(fig, update, frames=xmax, repeat=False)
plt.show()
"fun" is a function that returns an integer. FuncAnimation will repeatedly call "update", it will do that "xmax" times.
You can also use the .to_frame()
method.
If it is a Series, I assume 'Gene' is already the index, and will remain the index after converting it to a DataFrame. The name
argument of .to_frame()
will name the column.
x = x.to_frame('count')
If you want them both as columns, you can reset the index:
x = x.to_frame('count').reset_index()
Late answering, probably everybody knows about yield
now, but some better documentation has come along.
Adapting an example from "Javascript's Future: Generators" by James Long for the official Harmony standard:
function * foo(x) {
while (true) {
x = x * 2;
yield x;
}
}
"When you call foo, you get back a Generator object which has a next method."
var g = foo(2);
g.next(); // -> 4
g.next(); // -> 8
g.next(); // -> 16
So yield
is kind of like return
: you get something back. return x
returns the value of x
, but yield x
returns a function, which gives you a method to iterate toward the next value. Useful if you have a potentially memory intensive procedure that you might want to interrupt during the iteration.
localStorage
is something that is kept on the client side. There is no data transmitted to the server side.
You can only get the data with JavaScript and you can send it to the server side with Ajax.
It is work for me ("@material-ui/core": "^4.3.1"):
<Fragment>
<input
color="primary"
accept="image/*"
type="file"
onChange={onChange}
id="icon-button-file"
style={{ display: 'none', }}
/>
<label htmlFor="icon-button-file">
<Button
variant="contained"
component="span"
className={classes.button}
size="large"
color="primary"
>
<ImageIcon className={classes.extendedIcon} />
</Button>
</label>
</Fragment>
One more way is to extend the application (as my application was to inherit and customize the parent). It invokes the parent and its commandlinerunner automatically.
@SpringBootApplication
public class ChildApplication extends ParentApplication{
public static void main(String[] args) {
SpringApplication.run(ChildApplication.class, args);
}
}
Sorry for posting to such an old thread -- but as someone who also shares a passion for pythonic 'best', I thought I'd share our solution.
The solution is to build SQL statements using python's String Literal Concatenation (http://docs.python.org/), which could be qualified a somewhere between Option 2 and Option 4
Code Sample:
sql = ("SELECT field1, field2, field3, field4 "
"FROM table "
"WHERE condition1=1 "
"AND condition2=2;")
Works as well with f-strings:
fields = "field1, field2, field3, field4"
table = "table"
conditions = "condition1=1 AND condition2=2"
sql = (f"SELECT {fields} "
f"FROM {table} "
f"WHERE {conditions};")

Stealing from @Lila (couldn't make a comment because of no formatting), this shows the module's /path/, as well:
#!/usr/bin/env python
import sys
from modulefinder import ModuleFinder
finder = ModuleFinder()
# Pass the name of the python file of interest
finder.run_script(sys.argv[1])
# This is what's different from @Lila's script
finder.report()

I've got a solution for changing a value in specific CSS class. But it only works if you keep your CSS in the tag. If you just keep a link to your CSS from external files ex.
<style src='script.js'></style>
this solution won't work.
If your css looks like this for example:
<style id='style'>
.foo {
height:50px;
}
</style>
You can change a value of the tag using JS/jQuery.
I've written a function, perhaps it's not the best one but it works. You can improve it if you want.
function replaceClassProp(cl,prop,val){
if(!cl || !prop || !val){console.error('Wrong function arguments');return false;}
// Select style tag value
var tag = '#style';
var style = $(tag).text();
var str = style;
// Find the class you want to change
var n = str.indexOf('.'+cl);
str = str.substr(n,str.length);
n = str.indexOf('}');
str = str.substr(0,n+1);
var before = str;
// Find specific property
n = str.indexOf(prop);
str = str.substr(n,str.length);
n = str.indexOf(';');
str = str.substr(0,n+1);
// Replace the property with values you selected
var after = before.replace(str,prop+':'+val+';');
style=style.replace(before,after);
// Submit changes
$(tag).text(style);
}
Then just change the tag variable into your style tag id and exegute:
replaceClassProp('foo','height','50px');
The difference between this and $('.foo').css('height','50px'); is that when you do it with css method of jQuery, all elements that have .foo class will have visible style='height:50px' in DOM. If you do it my way, elements are untouched and the only thing youll see is class='foo'
Advantages
Disadvantages
Hope it helps anyhow.
Perhaps you could try to use the of
method of the Observable
class:
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';
public fetchModel(uuid: string = undefined): Observable<string> {
if(!uuid) {
return Observable.of(new TestModel()).map(o => JSON.stringify(o));
}
else {
return this.http.get("http://localhost:8080/myapp/api/model/" + uuid)
.map(res => res.text());
}
}
Need to include jquery-ui too:
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
You could do something like this:
htmlComponent.ts
htmlVariable: string = "<b>Some html.</b>";
//this is html in TypeScript code that you need to display
htmlComponent.html
<div [innerHtml]="htmlVariable"></div>
//this is how you display html code from TypeScript in your html
The join() method allows one thread to wait for the completion of another.However, as with sleep, join is dependent on the OS for timing, so you should not assume that join will wait exactly as long as you specify.
You could also consider using preparedStatement.setObject(index,value,type);
Valid regex tokens vary by implementation. A generic form is:
[0-9]+(\.[0-9][0-9]?)?
More compact:
\d+(\.\d{1,2})?
Both assume that both have at least one digit before and one after the decimal place.
To require that the whole string is a number of this form, wrap the expression in start and end tags such as (in Perl's form):
^\d+(\.\d{1,2})?$
To match numbers without a leading digit before the decimal (.12
) and whole numbers having a trailing period (12.
) while excluding input of a single period (.
), try the following:
^(\d+(\.\d{0,2})?|\.?\d{1,2})$
Wrapped the fractional portion in ()?
to make it optional. Be aware that this excludes forms such as 12.
Including that would be more like ^\d+\\.?\d{0,2}$
.
Use ^\d{1,6}(\.\d{1,2})?$
to stop repetition and give a restriction to whole part of the decimal value.
If you knew that the length of conditions you would care about would all be the same length then you could:
switch(mystring.substring(0, Math.Min(3, mystring.Length))
{
case "abc":
//do something
break;
case "xyz":
//do something else
break;
default:
//do a different thing
break;
}
The Math.Min(3, mystring.Length)
is there so that a string of less than 3 characters won't throw an exception on the sub-string operation.
There are extensions of this technique to match e.g. a bunch of 2-char strings and a bunch of 3-char strings, where some 2-char comparisons matching are then followed by 3-char comparisons. Unless you've a very large number of such strings though, it quickly becomes less efficient than simple if-else chaining for both the running code and the person who has to maintain it.
Edit: Added since you've now stated they will be of different lengths. You could do the pattern I mentioned of checking the first X chars and then the next Y chars and so on, but unless there's a pattern where most of the strings are the same length this will be both inefficient and horrible to maintain (a classic case of premature pessimisation).
The command pattern is mentioned in another answer, so I won't give details of that, as is that where you map string patterns to IDs, but they are option.
I would not change from if-else chains to command or mapping patterns to gain the efficiency switch sometimes has over if-else, as you lose more in the comparisons for the command or obtaining the ID pattern. I would though do so if it made code clearer.
A chain of if-else's can work pretty well, either with string comparisons or with regular expressions (the latter if you have comparisons more complicated than the prefix-matches so far, which would probably be simpler and faster, I'm mentioning reg-ex's just because they do sometimes work well with more general cases of this sort of pattern).
If you go for if-elses, try to consider which cases are going to happen most often, and make those tests happen before those for less-common cases (though of course if "starts with abcd" is a case to look for it would have to be checked before "starts with abc").
The solutions posted so far are needlessly complicated, in my opinion. There's a simpler way. The documentation of ui-router
says listen to $locationChangeSuccess
and use $urlRouter.sync()
to check a state transition, halt it, or resume it. But even that actually doesn't work.
However, here are two simple alternatives. Pick one:
$locationChangeSuccess
You can listen to $locationChangeSuccess
and you can perform some logic, even asynchronous logic there. Based on that logic, you can let the function return undefined, which will cause the state transition to continue as normal, or you can do $state.go('logInPage')
, if the user needs to be authenticated. Here's an example:
angular.module('App', ['ui.router'])
// In the run phase of your Angular application
.run(function($rootScope, user, $state) {
// Listen to '$locationChangeSuccess', not '$stateChangeStart'
$rootScope.$on('$locationChangeSuccess', function() {
user
.logIn()
.catch(function() {
// log-in promise failed. Redirect to log-in page.
$state.go('logInPage')
})
})
})
Keep in mind that this doesn't actually prevent the target state from loading, but it does redirect to the log-in page if the user is unauthorized. That's okay since real protection is on the server, anyway.
resolve
In this solution, you use ui-router
resolve feature.
You basically reject the promise in resolve
if the user is not authenticated and then redirect them to the log-in page.
Here's how it goes:
angular.module('App', ['ui.router'])
.config(
function($stateProvider) {
$stateProvider
.state('logInPage', {
url: '/logInPage',
templateUrl: 'sections/logInPage.html',
controller: 'logInPageCtrl',
})
.state('myProtectedContent', {
url: '/myProtectedContent',
templateUrl: 'sections/myProtectedContent.html',
controller: 'myProtectedContentCtrl',
resolve: { authenticate: authenticate }
})
.state('alsoProtectedContent', {
url: '/alsoProtectedContent',
templateUrl: 'sections/alsoProtectedContent.html',
controller: 'alsoProtectedContentCtrl',
resolve: { authenticate: authenticate }
})
function authenticate($q, user, $state, $timeout) {
if (user.isAuthenticated()) {
// Resolve the promise successfully
return $q.when()
} else {
// The next bit of code is asynchronously tricky.
$timeout(function() {
// This code runs after the authentication promise has been rejected.
// Go to the log-in page
$state.go('logInPage')
})
// Reject the authentication promise to prevent the state from loading
return $q.reject()
}
}
}
)
Unlike the first solution, this solution actually prevents the target state from loading.
server {
server_name xyz.com;
root /home/ubuntu/project_folder/;
client_max_body_size 10M;
access_log /var/log/nginx/project.access.log;
error_log /var/log/nginx/project.error.log;
location /static {
index index.html;
}
location /media {
alias /home/ubuntu/project/media/;
}
}
Server block to live the static page on nginx.
None of the above solutions worked for me. What finally worked was:
Instead of
import android.support.v4.content.FileProvider;
Use this
import androidx.core.content.FileProvider;
This path is updated as of AndroidX (the repackaged Android Support Library).
You can wrap all tasks which can fail in block, and use ignore_errors: yes
with that block.
tasks:
- name: ls
command: ls -la
- name: pwd
command: pwd
- block:
- name: ls non-existing txt file
command: ls -la no_file.txt
- name: ls non-existing pic
command: ls -la no_pic.jpg
ignore_errors: yes
Read more about error handling in blocks here.
An example of an associated full GC also shows the collectors used for the old and permanent generations:
3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)]
[ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K)
[PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]
Finally, breaking down one line of your example log output:
8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]
I create a common init for the designated and required. For convenience inits I delegate to init(frame:)
with frame of zero.
Having zero frame is not a problem because typically the view is inside a ViewController's view; your custom view will get a good, safe chance to layout its subviews when its superview calls layoutSubviews()
or updateConstraints()
. These two functions are called by the system recursively throughout the view hierarchy. You can use either updateContstraints()
or layoutSubviews()
. updateContstraints()
is called first, then layoutSubviews()
. In updateConstraints()
make sure to call super last. In layoutSubviews()
, call super first.
Here's what I do:
@IBDesignable
class MyView: UIView {
convenience init(args: Whatever) {
self.init(frame: CGRect.zero)
//assign custom vars
}
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
commonInit()
}
override func prepareForInterfaceBuilder() {
super.prepareForInterfaceBuilder()
commonInit()
}
private func commonInit() {
//custom initialization
}
override func updateConstraints() {
//set subview constraints here
super.updateConstraints()
}
override func layoutSubviews() {
super.layoutSubviews()
//manually set subview frames here
}
}
For variables describing distances, you would use \newlength
(and manipulate the values with \setlength
, \addlength
, \settoheight
, \settolength
and \settodepth
).
Similarly you have access to \newcounter
for things like section and figure numbers which should increment throughout the document. I've used this one in the past to provide code samples that were numbered separatly of other figures...
Also of note is \makebox
which allows you to store a bit of laid-out document for later re-use (and for use with \settolength
...).
jQuery is just a javascript library that makes some extra stuff available when writing javascript - so there is no reason to use jQuery for declaring variables. Use "regular" javascript:
var name = document.myForm.txtname.value;
alert(name);
EDIT: As Canavar points out in his example, it is also possible to use jQuery to get the form value:
var name = $('#txtname').val(); // Yes, it's called .val(), not .value()
given that the text box has its id
attribute set to txtname
. However, you don't need to use jQuery just because you can.
The following code outputs the number of words whose first and last letters are equal. Tested and verified using a python online compiler:
words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
count = 0
for i in words:
if i[0]==i[-1]:
count = count + 1
print(count)
Output:
$python main.py
3
if you don't want alert, that is u want html, then do this
...
$.each(data, function(index) {
$("#pr_result").append(data[index].dbcolumn);
});
...
NOTE: use "append" not "html" else the last result is what you will be seeing on your html view
then your html code should look like this
...
<div id="pr_result"></div>
...
You can also style (add class) the div in the jquery before it renders as html
This can happen when you run python script.py
