So it was a simple fix. Just had to move the ng-click
to a scope click handler:
<input id="upload"
type="file"
ng-file-select="onFileSelect($files)"
style="display: none;">
<button type="button"
ng-click="clickUpload()">Upload</button>
$scope.clickUpload = function(){
angular.element('#upload').trigger('click');
};
I would agree with @evillinux, It would be best to make your background image semi transparent so it supports < ie8
The other suggestions of using another div are also a great option, and it's the way to go if you want to do this in css. For example if the site had such features as selecting your own background color. I would suggest using a filter for older IE. eg:
filter:Alpha(opacity=50)
From reading the socket.io source code it looks like the "listen" method takes arguments (server, options, fn) and if "server" is an instance of an HTTP/S server it will simply wrap it for you.
So you could presumably give it an empty server which listens for the 'connection' event and handles the socket remoteAddress; however, things might be very difficult if you need to associate that address with an actual socket.io Socket object.
var http = require('http')
, io = require('socket.io');
io.listen(new http.Server().on('connection', function(sock) {
console.log('Client connected from: ' + sock.remoteAddress);
}).listen(80));
Might be easier to submit a patch to socket.io wherein their own Socket object is extended with the remoteAddress property assigned at connection time...
It denotes an rvalue reference. Rvalue references will only bind to temporary objects, unless explicitly generated otherwise. They are used to make objects much more efficient under certain circumstances, and to provide a facility known as perfect forwarding, which greatly simplifies template code.
In C++03, you can't distinguish between a copy of a non-mutable lvalue and an rvalue.
std::string s;
std::string another(s); // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(const std::string&);
In C++0x, this is not the case.
std::string s;
std::string another(s); // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(std::string&&);
Consider the implementation behind these constructors. In the first case, the string has to perform a copy to retain value semantics, which involves a new heap allocation. However, in the second case, we know in advance that the object which was passed in to our constructor is immediately due for destruction, and it doesn't have to remain untouched. We can effectively just swap the internal pointers and not perform any copying at all in this scenario, which is substantially more efficient. Move semantics benefit any class which has expensive or prohibited copying of internally referenced resources. Consider the case of std::unique_ptr
- now that our class can distinguish between temporaries and non-temporaries, we can make the move semantics work correctly so that the unique_ptr
cannot be copied but can be moved, which means that std::unique_ptr
can be legally stored in Standard containers, sorted, etc, whereas C++03's std::auto_ptr
cannot.
Now we consider the other use of rvalue references- perfect forwarding. Consider the question of binding a reference to a reference.
std::string s;
std::string& ref = s;
(std::string&)& anotherref = ref; // usually expressed via template
Can't recall what C++03 says about this, but in C++0x, the resultant type when dealing with rvalue references is critical. An rvalue reference to a type T, where T is a reference type, becomes a reference of type T.
(std::string&)&& ref // ref is std::string&
(const std::string&)&& ref // ref is const std::string&
(std::string&&)&& ref // ref is std::string&&
(const std::string&&)&& ref // ref is const std::string&&
Consider the simplest template function- min and max. In C++03 you have to overload for all four combinations of const and non-const manually. In C++0x it's just one overload. Combined with variadic templates, this enables perfect forwarding.
template<typename A, typename B> auto min(A&& aref, B&& bref) {
// for example, if you pass a const std::string& as first argument,
// then A becomes const std::string& and by extension, aref becomes
// const std::string&, completely maintaining it's type information.
if (std::forward<A>(aref) < std::forward<B>(bref))
return std::forward<A>(aref);
else
return std::forward<B>(bref);
}
I left off the return type deduction, because I can't recall how it's done offhand, but that min can accept any combination of lvalues, rvalues, const lvalues.
Least amount of markup possible (you only need one span):
<p>This text is left. <span>This text is right.</span></p>
How you want to achieve the left/right styles is up to you, but I would recommend an external style on an ID or a class.
The full HTML:
<p class="split-para">This text is left. <span>This text is right.</span></p>
And the CSS:
.split-para { display:block;margin:10px;}
.split-para span { display:block;float:right;width:50%;margin-left:10px;}
What about this alternative idea :

scheduledExecutor.shutdownNow();
}
long getCurrentMillisecondsTime()

If you are comfortable with Visual Studio environment,

I heard there are emulators, but I could find only Apple II Emulator http://virtualapple.org/. It looks like limited to games.
I have seen this on Windows, with msysgit 1.7.2.3. You have to fix the path to bin/curl-ca-bundle.crt. I had to specify the absolute path, using back-slashes:
git config --system http.sslcainfo "C:\Program Files (x86)\git\bin\curl-ca-bundle.crt"
This will result in changes to [git-install-dir]/etc/gitconfig file, which may be edited directly, too.

!= is OK to compare two variables. It doesn't work, though, with multiple comparisons.
I have improved batch file with yes or no prompt. If user enter any character except y and n , then it will again prompt user for valid input. It Works for me.
@echo off
:ConfirmBox
set /P c= Are you sure want to contine (y/n)?
if /I "%c%" EQU "Y" (
goto :FnYes
) else if /I "%c%" EQU "N" (
goto :FnNo
) else (
goto :InValid
)
:FnYes
echo You have entered Y
goto :END
:FnNo
echo You have entered N
goto :END
:InValid
echo Invalid selection. Enter Y or N
goto :ConfirmBox
:END
pause
exit
/I in if condition will validate both lowercase and uppercase characters.
According to How to convert Strings to and from UTF8 byte arrays in Java:
String s = "some text here";
byte[] b = s.getBytes("UTF-8");
System.out.println(b.length);
import time
class CachedItem(object):
def __init__(self, key, value, duration=60):
self.key = key
self.value = value
self.duration = duration
self.timeStamp = time.time()
def __repr__(self):
return '<CachedItem {%s:%s} expires at: %s>' % (self.key, self.value, time.time() + self.duration)
class CachedDict(dict):
def get(self, key, fn, duration):
if key not in self \
or self[key].timeStamp + self[key].duration < time.time():
print 'adding new value'
o = fn(key)
self[key] = CachedItem(key, o, duration)
else:
print 'loading from cache'
return self[key].value
if __name__ == '__main__':
fn = lambda key: 'value of %s is None' % key
ci = CachedItem('a', 12)
print ci
cd = CachedDict()
print cd.get('a', fn, 5)
time.sleep(2)
print cd.get('a', fn, 6)
print cd.get('b', fn, 6)
time.sleep(2)
print cd.get('a', fn, 7)
print cd.get('b', fn, 7)
%s is the representation of an array of char
char string[10] // here is a array of chars, they max length is 10;
char character; // just a char 1 letter/from the ascii map
character = 'a'; // assign 'a' to character
printf("character %c ",a); //we will display 'a' to stout
so string is an array of char we can assign multiple character per space of memory
string[0]='h';
string[1]='e';
string[2]='l';
string[3]='l';
string[4]='o';
string[5]=(char) 0;//asigning the last element of the 'word' a mark so the string ends
this assignation can be done at initialization like char word="this is a word" // the word array of chars got this string now and is statically defined
toy can also assign values to the array of chars assigning it with functions like strcpy;
strcpy(string,"hello" );
this do the same as the example and automatically add the (char) 0 at the end
so if you print it with %S printf("my string %s",string);
and how string is a array we can just display part of it
// the array one char
printf("first letter of wrd %s is :%c ",string,string[1] );
You are using the wrong URL (you are using the URL for the html webpage). Try either of these instead:
https://github.com/facebook/facebook-android-sdk.git
git://github.com/facebook/facebook-android-sdk.git
If you use jQuery and would need an inline solution, this would work very well;
<a href="#" onclick="$(this).closest('form').submit();">submit form</a>
Also, you might want to replace
<a href="#">text</a>
with
<a href="javascript:void(0);">text</a>
so the user does not scroll to the top of your page when clicking the link.
Pelo Hyper-V:
private PerformanceCounter theMemCounter = new PerformanceCounter(
"Hyper-v Dynamic Memory VM",
"Physical Memory",
Process.GetCurrentProcess().ProcessName);
Use localStorage to store the fact that you opened the page :
$(document).ready(function() {
var yetVisited = localStorage['visited'];
if (!yetVisited) {
// open popup
localStorage['visited'] = "yes";
}
});
Restarted the Device, Worked! :D
Thanks Everyone for the great suggestions.
Use like this (source):
function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie = c_name+"="+c_value+"; path=/";
}
Maybe this way...
ResponseEntity<Object[]> responseEntity = restTemplate.getForEntity(urlGETList, Object[].class);
Object[] objects = responseEntity.getBody();
MediaType contentType = responseEntity.getHeaders().getContentType();
HttpStatus statusCode = responseEntity.getStatusCode();
Controller code for the RequestMapping
@RequestMapping(value="/Object/getList/", method=RequestMethod.GET)
public @ResponseBody List<Object> findAllObjects() {
List<Object> objects = new ArrayList<Object>();
return objects;
}
ResponseEntity
is an extension of HttpEntity
that adds a HttpStatus
status code. Used in RestTemplate
as well @Controller
methods.
In RestTemplate
this class is returned by getForEntity()
and exchange()
.
It gets serialized so that the URI can read the name value pairs in the POST request by default. You could try setting processData:false to your list of params. Not sure if that would help.
Just set using JS as follows:
<script>
var vid = document.getElementById("myVideo");
vid.autoplay = false;
vid.load();
</script>
Set true
to turn on autoplay. Set false
to turn off autoplay.
http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_av_prop_autoplay
You can use any of the below code to get the controller name
@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString();
If you are using MVC 3 you can use
@ViewContext.Controller.ValueProvider.GetValue("controller").RawValue
Another way to think about Return-Path
vs Reply-To
is to compare it to snail mail.
When you send an envelope in the mail, you specify a return address. If the recipient does not exist or refuses your mail, the postmaster returns the envelope back to the return address. For email, the return address is the Return-Path
.
Inside of the envelope might be a letter and inside of the letter it may direct the recipient to "Send correspondence to example address". For email, the example address is the Reply-To
.
In essence, a Postage Return Address is comparable to SMTP's Return-Path
header and SMTP's Reply-To
header is similar to the replying instructions contained in a letter.

I prefer to open all links inside the standalone web app mode except ones that have target="_blank". Using jQuery, of course.
$(document).on('click', 'a', function(e) {
if ($(this).attr('target') !== '_blank') {
e.preventDefault();
window.location = $(this).attr('href');
}
});
As myJSON
is an object you can just set its properties, for example:
myJSON.list1 = ["1","2"];
If you dont know the name of the properties, you have to use the array access syntax:
myJSON['list'+listnum] = ["1","2"];
If you want to add an element to one of the properties, you can do;
myJSON.list1.push("3");
assuming certain column names...
INSERT one
newToner = Toner(toner_id = 1,

toner_color = 'blue',
toner_hex = '#0F85FF')
newToner2 = Toner(toner_id = 2,
toner_color = 'red',

I removed an old project from the solution, after that the error occurred. I had to open the .sln file in notepad and delete the .dll reference tot he old project that I removed. After that it worked.
Set up a trap (you can trap several signals with one handler):
signal (SIGQUIT, my_handler); signal (SIGINT, my_handler);
Handle the signal however you want, but be aware of limitations and gotchas:
void my_handler (int sig) { /* Your code here. */ }
After experiencing issues with sites breaking on Edge when using High Contrast Mode, I came across the following work by Jeff Clayton:
https://browserstrangeness.github.io/css_hacks.html
It's a crazy, weird media query, but those are easier to use in Sass:
@media screen and (min-width:0\0) and (min-resolution:+72dpi), \0screen\,screen\9 {
.selector { rule: value };
}
This targets IE versions expect for IE8.
Or you can use:
@media screen\0 {
.selector { rule: value };
}
Which targets IE8-11, but also triggers FireFox 1.x (which for my use case, doesn't matter).
Right now I'm testing with print support, and this seems to be working okay:
@media all\0 {
.selector { rule: value };
}
I am using Windows 8 and the above solutions did not work out for me. I downgraded Postgres from 9.4 to 9.3. Man,it worked :)
You should use the following code from the support library instead:
ContextCompat.getDrawable(context, R.drawable.***)
Using this method is equivalent to calling:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
return resources.getDrawable(id, context.getTheme());
} else {
return resources.getDrawable(id);
}
As of API 21, you should use the getDrawable(int, Theme)
method instead of getDrawable(int)
, as it allows you to fetch a drawable object associated with a particular resource ID for the given screen density/theme. Calling the deprecated getDrawable(int)
method is equivalent to calling getDrawable(int, null)
.
JAXB is simple to use and is included in Java 6 SE. With JAXB, or other XML data binding such as Simple, you don't have to handle the XML yourself, most of the work is done by the library. The basic usage is to add annotation to your existing POJO. These annotation are then used to generate an XML Schema for you data and also when reading/writing your data from/to a file.
This the basic usage of allocate/DE-allocate pattern in c++
malloc
/free
, new
/delete
, new[]
/delete[]
We need to use them correspondingly. But I would like to add this particular understanding for the difference between delete
and delete[]
1) delete
is used to de-allocate memory allocated for single object
2) delete[]
is used to de-allocate memory allocated for array of objects
class ABC{}
ABC *ptr = new ABC[100]
when we say new ABC[100]
, compiler can get the information about how many objects that needs to be allocated(here it is 100) and will call the constructor for each of the objects created
but correspondingly if we simply use delete ptr
for this case, compiler will not know how many objects that ptr
is pointing to and will end up calling of destructor and deleting memory for only 1 object(leaving the invocation of destructors and deallocation of remaining 99 objects). Hence there will be a memory leak.
so we need to use delete [] ptr
in this case.
Actually I had wrongly put href="", and hence the html file was referencing itself as the CSS. Mozilla had the similar bug once, and I got the answer from there.

Your solution shows the issue here -- play
is not a jQuery function but a function of the DOM element. You therefore need to call it upon the DOM element. You give an example of how to do this with the native DOM functions. The jQuery equivalent -- if you wanted to do this to fit in with an existing jQuery selection -- would be $('#videoId').get(0).play()
. (get
gets the native DOM element from the jQuery selection.)
The error regarding the file extension has been handled, you either use BMP
(without the dot) or pass the output name with the extension already. Now to handle the error you need to properly modify your data in the frequency domain to be saved as an integer image, PIL
is telling you that it doesn't accept float data to save as BMP.
Here is a suggestion (with other minor modifications, like using fftshift
and numpy.array
instead of numpy.asarray
) for doing the conversion for proper visualization:
import sys
import numpy
from PIL import Image
img = Image.open(sys.argv[1]).convert('L')
im = numpy.array(img)
fft_mag = numpy.abs(numpy.fft.fftshift(numpy.fft.fft2(im)))
visual = numpy.log(fft_mag)
visual = (visual - visual.min()) / (visual.max() - visual.min())
result = Image.fromarray((visual * 255).astype(numpy.uint8))
result.save('out.bmp')
I think best way is check if request is of type "OPTIONS" return 200 from middle ware. It worked for me.
express.use('*',(req,res,next) =>{
if (req.method == "OPTIONS") {
res.status(200);
res.send();
}else{
next();
}
});
var result = new StringBuilder();
for (int i = 0; i < table.Columns.Count; i++)
{
result.Append(table.Columns[i].ColumnName);
result.Append(i == table.Columns.Count - 1 ? "\n" : ",");
}
foreach (DataRow row in table.Rows)
{
for (int i = 0; i < table.Columns.Count; i++)
{
result.Append(row[i].ToString());
result.Append(i == table.Columns.Count - 1 ? "\n" : ",");
}
}
File.WriteAllText("test.csv", result.ToString());
I used a combination of the above to achieve a working result; Change float to Left and display Block the li itself HTML:
<ol class="foo">
<li>bar1</li>
<li>bar2</li>
</ol>
CSS:
.foo li {
display: block;
float: left;
width: 100px;
height: 100px;
border: 1px solid black;
margin: 2px;
}
Besides the 'console
' usage issue mentioned in accepted answer and others,there is at least another reason why sometimes pages in Internet Explorer work only with the developer tools activated.
When Developer Tools is enabled, IE doesn't really uses its HTTP cache (at least by default in IE 11) like it does in normal mode.
It means if your site or page has a caching problem (if it caches more than it should for example - that was my case), you will not see that problem in F12 mode. So if the javascript does some cached AJAX requests, they may not work as expected in normal mode, and work fine in F12 mode.
If you want to separate the commands into one command per file, you can do
cmd /c start C:\Users\Yiwei\Downloads\putty.exe -load "MathCS-labMachine1"
and in the other file, you can do
cmd /c start "" "C:\Program Files (x86)\Xming\Xming.exe" :0 -clipboard -multiwindow
The command cmd /c will close the command-prompt window after the exe was run.
You can appendChild
to document.body
but not if the document hasn't been loaded. So you should
put everything in:
window.onload=function(){
//your code
}
This works or you can make appendChild
to be dependent on something else like another event for eg.
https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_doc_body_append
As a matter of fact you can try changing the innerHTML
of the document.body
it works...!
Your file has syntax error, so your file was not interpreted, so settings was not changed and you have blank page.
You can separate your file to two.
index.php
<?php
ini_set("display_errors", "1");
error_reporting(E_ALL);
include 'error.php';
error.php
<?
echo('catch this -> ' ;. $thisdoesnotexist);
If you are on a Mac, press command shift G and in the box type /users and then go, next click on your user name and navigate to netbeansprojects and open it. Then delete the ones in there that are causing problems. You can then create your project.
Note: I had moved my wordpress folder to my desktop trying to figure this out, so I dropped it back into the origional location and it works fine. So if you did this, just replace the wordpress folder after deleting the problem projects from the netbeansprojects folder and its contents back to the original installation folder.
Hope this helps...:)
A simpler way of doing it is:
var dictionary = list.GroupBy(it => it.Key).ToDictionary(dict => dict.Key, dict => dict.Select(item => item.value).ToList());
This being a very old question but worth adding that I have just had a similar issue where a background colour on a footer
element in my case didn't show. I added a position: relative
which worked.
A separate use case: when your text file is version controlled (in this case specifically under git although it applies to others too). If content is added to the end of the file, then the line that was previously the last line will have been edited to include a newline character. This means that blame
ing the file to find out when that line was last edited will show the text addition, not the commit before that you actually wanted to see.
It all depends on how big the unit of work, but I guess you're trying to treat each <product/>
nodes in succession.
For that, the simplest way would be to use XMLReader to get to each node, then use SimpleXML to access them. This way, you keep the memory usage low because you're treating one node at a time and you still leverage SimpleXML's ease of use. For instance:
$z = new XMLReader;
$z->open('data.xml');
$doc = new DOMDocument;
// move to the first <product /> node
while ($z->read() && $z->name !== 'product');
// now that we're at the right depth, hop to the next <product/> until the end of the tree
while ($z->name === 'product')
{
// either one should work
//$node = new SimpleXMLElement($z->readOuterXML());
$node = simplexml_import_dom($doc->importNode($z->expand(), true));
// now you can use $node without going insane about parsing
var_dump($node->element_1);
// go to next <product />
$z->next('product');
}
Quick overview of pros and cons of different approaches:
XMLReader only
Pros: fast, uses little memory
Cons: excessively hard to write and debug, requires lots of userland code to do anything useful. Userland code is slow and prone to error. Plus, it leaves you with more lines of code to maintain
XMLReader + SimpleXML
Pros: doesn't use much memory (only the memory needed to process one node) and SimpleXML is, as the name implies, really easy to use.
Cons: creating a SimpleXMLElement object for each node is not very fast. You really have to benchmark it to understand whether it's a problem for you. Even a modest machine would be able to process a thousand nodes per second, though.
XMLReader + DOM
Pros: uses about as much memory as SimpleXML, and XMLReader::expand() is faster than creating a new SimpleXMLElement. I wish it was possible to use simplexml_import_dom()
but it doesn't seem to work in that case
Cons: DOM is annoying to work with. It's halfway between XMLReader and SimpleXML. Not as complicated and awkward as XMLReader, but light years away from working with SimpleXML.
My advice: write a prototype with SimpleXML, see if it works for you. If performance is paramount, try DOM. Stay as far away from XMLReader as possible. Remember that the more code you write, the higher the possibility of you introducing bugs or introducing performance regressions.
For me the issue was with a dash "-" in the window name field. I removed the dashes and IE does not error out and in fact opens the window.
I used Adobe's detection kit, originally suggested by justpassinby. Their system is nice because it detects the version number and compares it for you against your 'required version'
One bad thing is it does an alert showing the detected version of flash, which isn't very user friendly. All of a sudden a box pops up with some seemingly random numbers.
Some modifications you might want to consider:
A workaround for CONTAINS
: If you don't want to create a full text Index on the column, and performance is not one of your priorities you could use the LIKE
statement which doesn't need any prior configuration:
Example: find all Products that contains the letter Q:
SELECT ID, ProductName
FROM [ProductsDB].[dbo].[Products]
WHERE [ProductsDB].[dbo].[Products].ProductName LIKE '%Q%'
If you'll be using the standard shell of the operating system, you can get the result much faster rather than using pure pythonic way.
Example for Windows:
import os
import subprocess
def get_num_files(path):
cmd = 'DIR \"%s\" /A-D /B /S | FIND /C /V ""' % path
return int(subprocess.check_output(cmd, shell=True))
# Initialize variables
new_list = []
i = 0
# Iterate through the list
for i in range(len(elements)):
# Does this element belong in the resulting list?
if i%2==0:
# Add this element to the resulting list
new_list.append(elements[i])
# Increment i
i +=2
return new_list

Yes they do.
You shouldn't really be overriding the constructor anyway. You should have a newInstance()
static method defined and pass any parameters via arguments (bundle)
For example:
public static final MyFragment newInstance(int title, String message) {
MyFragment f = new MyFragment();
Bundle bdl = new Bundle(2);
bdl.putInt(EXTRA_TITLE, title);
bdl.putString(EXTRA_MESSAGE, message);
f.setArguments(bdl);
return f;
}
And of course grabbing the args this way:
@Override
public void onCreate(Bundle savedInstanceState) {
title = getArguments().getInt(EXTRA_TITLE);
message = getArguments().getString(EXTRA_MESSAGE);
//...
//etc
//...
}
Then you would instantiate from your fragment manager like so:
@Override
public void onCreate(Bundle savedInstanceState) {
if (savedInstanceState == null){
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.content, MyFragment.newInstance(
R.string.alert_title,
"Oh no, an error occurred!")
)
.commit();
}
}
This way if detached and re-attached the object state can be stored through the arguments. Much like bundles attached to Intents.
Reason - Extra reading
I thought I would explain why for people wondering why.
If you check: https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/app/Fragment.java
You will see the instantiate(..)
method in the Fragment
class calls the newInstance
method:
public static Fragment instantiate(Context context, String fname, @Nullable Bundle args) {
try {
Class<?> clazz = sClassMap.get(fname);
if (clazz == null) {
// Class not found in the cache, see if it's real, and try to add it
clazz = context.getClassLoader().loadClass(fname);
if (!Fragment.class.isAssignableFrom(clazz)) {
throw new InstantiationException("Trying to instantiate a class " + fname
+ " that is not a Fragment", new ClassCastException());
}
sClassMap.put(fname, clazz);
}
Fragment f = (Fragment) clazz.getConstructor().newInstance();
if (args != null) {
args.setClassLoader(f.getClass().getClassLoader());
f.setArguments(args);
}
return f;
} catch (ClassNotFoundException e) {
throw new InstantiationException("Unable to instantiate fragment " + fname
+ ": make sure class name exists, is public, and has an"
+ " empty constructor that is public", e);
} catch (java.lang.InstantiationException e) {
throw new InstantiationException("Unable to instantiate fragment " + fname
+ ": make sure class name exists, is public, and has an"
+ " empty constructor that is public", e);
} catch (IllegalAccessException e) {
throw new InstantiationException("Unable to instantiate fragment " + fname
+ ": make sure class name exists, is public, and has an"
+ " empty constructor that is public", e);
} catch (NoSuchMethodException e) {
throw new InstantiationException("Unable to instantiate fragment " + fname
+ ": could not find Fragment constructor", e);
} catch (InvocationTargetException e) {
throw new InstantiationException("Unable to instantiate fragment " + fname
+ ": calling Fragment constructor caused an exception", e);
}
}
http://docs.oracle.com/javase/6/docs/api/java/lang/Class.html#newInstance() Explains why, upon instantiation it checks that the accessor is public
and that that class loader allows access to it.
It's a pretty nasty method all in all, but it allows the FragmentManger
to kill and recreate Fragments
with states. (The Android subsystem does similar things with Activities
).
Example Class
I get asked a lot about calling newInstance
. Do not confuse this with the class method. This whole class example should show the usage.

The Actual solution of this problem is changing first line in web.php
Just replace Welcome route with following route
Route::view('/', 'welcome');
If still getting same error than you probab
Use like this!
interface Iinput {
label: string
placeholder: string
register: any
type?: string
required: boolean
}
// This is how it can be done
const inputs: Array<Iinput> = [
{
label: "Title",
placeholder: "Bought something",
register: register,
required: true,
},
]
As others recommend, you can use Oracle SQL Developer. You can point to the location of the script to run it, as described. A slightly simpler method, though, is to just use drag-and-drop:
I usually use the .ToString() method on exceptions to present the full exception information (including the inner stack trace) in text:
catch (MyCustomException ex)
{
Debug.WriteLine(ex.ToString());
}
Sample output:
ConsoleApplication1.MyCustomException: some message .... ---> System.Exception: Oh noes!
at ConsoleApplication1.SomeObject.OtherMethod() in C:\ConsoleApplication1\SomeObject.cs:line 24
at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 14
--- End of inner exception stack trace ---
at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 18
at ConsoleApplication1.Program.DoSomething() in C:\ConsoleApplication1\Program.cs:line 23
at ConsoleApplication1.Program.Main(String[] args) in C:\ConsoleApplication1\Program.cs:line 13
In general, no. int(wchar_t(255)) == int(char(255))
of course, but that just means they have the same int value. They may not represent the same characters.
You would see such a discrepancy in the majority of Windows PCs, even. For instance, on Windows Code page 1250, char(0xFF)
is the same character as wchar_t(0x02D9)
(dot above), not wchar_t(0x00FF)
(small y with diaeresis).
Note that it does not even hold for the ASCII range, as C++ doesn't even require ASCII. On IBM systems in particular you may see that 'A' != 65
Just default the variable to the expected type:
(number=1) => ...
(number=1.0) => ...
(string='str') ...
#include <stdio.h>
#include <string.h>
int main() {
char src[] = "SexDrugsRocknroll";
char dest[5] = { 0 }; // 4 chars + terminator */
int len = strlen(src);
int i = 0;
while (i*4 < len) {
strncpy(dest, src+(i*4), 4);
i++;
printf("loop %d : %s\n", i, dest);
}
}
crontab does not understand "intervals", it only understands "schedule"
valid hours: 0-23 -- valid minutes: 0-59

this means "run when the minute of each hour is 30" (would run at: 1:30, 2:30, 3:30, etc)
example #2
*/30 * * * * your_command
this means "run when the minute of each hour is evenly divisible by 30" (would run at: 1:30, 2:00, 2:30, 3:00, etc)

Hope this has been helpful.
you can use jQuery. which make it very simple.
just download the jQuery file add jQuery into your HTML
or you can user online link:

and try this:
$("#divID").append(data);
This BFS-like solution is pretty straightforward. Simply jumps levels one-by-one.
def getHeight(self,root, method='links'):
c_node = root
cur_lvl_nodes = [root]
nxt_lvl_nodes = []
height = {'links': -1, 'nodes': 0}[method]
while(cur_lvl_nodes or nxt_lvl_nodes):
for c_node in cur_lvl_nodes:
for n_node in filter(lambda x: x is not None, [c_node.left, c_node.right]):
nxt_lvl_nodes.append(n_node)
cur_lvl_nodes = nxt_lvl_nodes
nxt_lvl_nodes = []
height += 1
return height
I used this to start a cmd file from C#:
Process proc = new Process();

proc.StartInfo.FileName = "myFileName.cmd";
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
proc.WaitForExit();
BigDecimal decPrec = (BigDecimal)yo.get("Avg");
decPrec = decPrec.setScale(5, RoundingMode.CEILING);
String value= String.valueOf(decPrec);
This way you can set specific precision of a BigDecimal
.
The value of decPrec was 1.5726903423607562595809913132345426
which is rounded off to 1.57267
.
The NuGet documentation provides instructions on how to accomplish this and I just followed them successfully for Visual Studio 2015 & Visual Studio 2017 against VSTS (Azure-hosted TFS). Everything is fully updated as of Nov 2016 Aug 2018.
I recommend you follow NuGet's instructions but just to recap what I did:
packages
folder is not committed to TFS. If it is, get it out of there..sln
file exists in unless otherwise specified (NuGet's instructions aren't completely clear on this)..nuget
folder. You can use Windows Explorer to name it .nuget.
for it to successfully save as .nuget
(it automatically removes the last period) but directly trying to name it .nuget
may not work (you may get an error or it may change the name, depending on your version of Windows).
Or name the directory nuget, and open the parent directory in command line prompt. type. ren nuget .nugetNuGet.config
file and add the following contents and save it:NuGet.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<solution>
<add key="disableSourceControlIntegration" value="true" />
</solution>
</configuration>
.sln
's folder and create a new text file and name it .tfignore
(if using Windows Explorer, use the same trick as above and name it .tfignore.
).tfignore:
# Ignore the NuGet packages folder in the root of the repository.
# If needed, prefix 'packages' with additional folder names if it's
# not in the same folder as .tfignore.
packages
# include package target files which may be required for msbuild,
# again prefixing the folder name as needed.
!packages/*.targets
.tfignore
file and .nuget
folder to all of my various solutions and committed them and I no longer have the packages
folder trying to sneak into my source control repo!While not mine, I have found this .tfignore
template by sirkirby to be handy. The example in my answer covers the Nuget packages
folder but this template includes some other things as well as provides additional examples that can be useful if you wish to customize this further.
From what i have observed there might be two reasons for this Exception to occur: (1)Your Driver name is not spelled Correctly. (2)Driver hasn't been Associated Properly with the Java Project Steps to follow in Eclipse: (1)Create a new Java Project. (2)copy The connector Jar file (3)Right Click on the Java project and paste it there. (4)Right click on the Java project -> Properties ->Java Build Path - >libraries-> Add Jar ->choose ur project(select the jar file from dropdown) and click ok.
Spring MVC is deeply integreated in Spring, Struts MVC is not.
Of course! jQuery is just a library that utilizes javascript after all.
You can use document.getElementById to get the element in question, then change its height accordingly, through element.style.height.
elementToChange = document.getElementById('collapseableEl');
elementToChange.style.height = '100%';
Wrap that up in a neat little function that caters for toggling back and forth and you have yourself a solution.
I suspect that the SelectedItem property of the ComboBox does not change until the control has been validated (which occurs when the control loses focus), whereas the SelectedValue property changes whenever the user selects an item.
Here is a reference to the focus events that occur on controls:
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.validated.aspx
You have writer.close();
in your code. So bash receives EOF on its stdin
and exits. Then you get Broken pipe
when trying to read from the stdout
of the defunct bash.
If I understand your question correctly this should solve it:
HTML - create a simple input field.
<input type="text" id="giraffe" />
CSS - clear out the native outline so you can set your own and it doesn't look weird with a bluey red outline.
input:focus {
outline: none;
}
.error-input-border {
border: 1px solid #FF0000;
}
JS - on typing in the field set red border class declared in the CSS
document.getElementById('giraffe').oninput = function() { this.classList.add('error-input-border'); }

You would need to attach your click event to some element. If there are lots of other elements on the page you would not want to attach a click event to all of them.
One potential way would be to create a transparent div below your dropdown menu but above all other elements on the page. You would show it when the drop down was shown. Have the element have a click hander that hides the drop down and the transparent div.
$('#clickCatcher').click(function () { _x000D_
$('#dropContainer').hide();_x000D_
$(this).hide();_x000D_
});
_x000D_
#dropContainer { z-index: 101; ... }_x000D_
#clickCatcher { position: absolute; top: 0; left: 0; width: 100%; height: 100%; z-index: 100; }
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="dropDown"></div>_x000D_
<div id="clickCatcher"></div>
_x000D_
Here is the jsFiddle
#backdrop{
border: 2px solid red;
width: 400px;
height: 200px;
position: absolute;
}
#curtain {
border: 1px solid blue;
width: 400px;
height: 200px;
position: absolute;
}
Use Z-index to move the one you want on top.
One case where *args and **kwargs are useful is when writing wrapper functions (such as decorators) that need to be able accept arbitrary arguments to pass through to the function being wrapped. For example, a simple decorator that prints the arguments and return value of the function being wrapped:
def mydecorator( f ):
@functools.wraps( f )
def wrapper( *args, **kwargs ):
print "Calling f", args, kwargs
v = f( *args, **kwargs )
print "f returned", v
return v
return wrapper

}
You need to add CSS to .active
instead of .active a
.

This problem can be caused by undue manipulation of the enabled cipher suites at the client or the server, but I suspect the most common cause is the server not having a private key and certificate at all.
NB:
ssl.setEnabledCipherSuites(sc.getServerSocketFactory().getSupportedCipherSuites());
Get rid of this line. Your server is insecure enough already with that insecure TrustManager
. Then run your server with -Djavax.net.debug=SSL,handshake,
try one connect, and post the resulting output here.
If you only want to Close the form than you can use this.Close(); else if you want the whole application to be closed use Application.Exit();
Integer.toBinaryString((byteValue & 0xFF) + 256).substring(1)
In most cases getting rid of infinite and null values solve this problem.
get rid of infinite values.
df.replace([np.inf, -np.inf], np.nan, inplace=True)
get rid of null values the way you like, specific value such as 999, mean, or create your own function to impute missing values
df.fillna(999, inplace=True)
I had to run project in VS2010 and I could not introduce any modifications in the code. My solution was to install vS2013 and in VS2010 point VC++ Directories->IncludeDirectories to Program Files(x86)\Microsoft Visual Studio 12.0\VC\include. Then my project compiled without any issues.
It worked for me this way:
Step1: Open System Preference > MySQL > Initialize Database.
Step2: Put password you used while installing MySQL.
Step3: Start MySQL server.
Step4: Come back to MySQL Workbench and double connect/ create a new one.

From above answers i created this example for date generator
import datetime
date = datetime.datetime.now()
time = date.time()
def date_generator(date, delta):
counter =0
date = date - datetime.timedelta(days=delta)
while counter <= delta:
yield date
date = date + datetime.timedelta(days=1)
counter +=1
for date in date_generator(date, 30):
if date.date() != datetime.datetime.now().date():
start_date = datetime.datetime.combine(date, datetime.time())
end_date = datetime.datetime.combine(date, datetime.time.max)
else:
start_date = datetime.datetime.combine(date, datetime.time())
end_date = datetime.datetime.combine(date, time)
print('start_date---->',start_date,'end_date---->',end_date)
look at String.indexOf
and String.substring
.
Make sure you check for -1 for indexOf
.
I think this might help...
In order to break down user inputted dates (mm/dd/yyyy) in my scripts, I store the day, month, and year into an array, and then put the values into separate variables as follows:
DATE_ARRAY=(`echo $2 | sed -e 's/\// /g'`)
MONTH=(`echo ${DATE_ARRAY[0]}`)
DAY=(`echo ${DATE_ARRAY[1]}`)
YEAR=(`echo ${DATE_ARRAY[2]}`)
You can change the eclipse tomcat server configuration. Open the server view, double click on you server to open server configuration. Then click to activate "Publish module contents to separate XML files". Finally, restart your server, the message must disappear.
It represents the textual contents of a given HTML tag. Can also contain tags of its own.
unique_ptr
is a smart pointer which owns an object exclusively.
shared_ptr
is a smart pointer for shared ownership. It is both copyable
and movable
. Multiple smart pointer instances can own the same resource. As soon as the last smart pointer owning the resource goes out of scope, the resource will be freed.
As an alternative, you can use recursion-
struct node* reverseList(struct node *head)
{
if(head == NULL) return NULL;
if(head->next == NULL) return head;
struct node* second = head->next;
head->next = NULL;
struct node* remaining = reverseList(second);
second->next = head;
return remaining;
}
There's a list. There is also a putative C++ frontend on splint.
Here in 2017, Promises are built into JavaScript, they were added by the ES2015 spec (polyfills are available for outdated environments like IE8-IE11). The syntax they went with uses a callback you pass into the Promise
constructor (the Promise
executor) which receives the functions for resolving/rejecting the promise as arguments.
First, since async
now has a meaning in JavaScript (even though it's only a keyword in certain contexts), I'm going to use later
as the name of the function to avoid confusion.
Using native promises (or a faithful polyfill) it would look like this:
function later(delay) {
return new Promise(function(resolve) {
setTimeout(resolve, delay);
});
}
Note that that assumes a version of setTimeout
that's compliant with the definition for browsers where setTimeout
doesn't pass any arguments to the callback unless you give them after the interval (this may not be true in non-browser environments, and didn't used to be true on Firefox, but is now; it's true on Chrome and even back on IE8).
If you want your function to optionally pass a resolution value, on any vaguely-modern browser that allows you to give extra arguments to setTimeout
after the delay and then passes those to the callback when called, you can do this (current Firefox and Chrome; IE11+, presumably Edge; not IE8 or IE9, no idea about IE10):
function later(delay, value) {
return new Promise(function(resolve) {
setTimeout(resolve, delay, value); // Note the order, `delay` before `value`
/* Or for outdated browsers that don't support doing that:
setTimeout(function() {
resolve(value);
}, delay);
Or alternately:
setTimeout(resolve.bind(null, value), delay);
*/
});
}
If you're using ES2015+ arrow functions, that can be more concise:
function later(delay, value) {
return new Promise(resolve => setTimeout(resolve, delay, value));
}
or even
const later = (delay, value) =>
new Promise(resolve => setTimeout(resolve, delay, value));
If you want to make it possible to cancel the timeout, you can't just return a promise from later
, because promises can't be cancelled.
But we can easily return an object with a cancel
method and an accessor for the promise, and reject the promise on cancel:
const later = (delay, value) => {
let timer = 0;
let reject = null;
const promise = new Promise((resolve, _reject) => {
reject = _reject;
timer = setTimeout(resolve, delay, value);
});
return {
get promise() { return promise; },
cancel() {
if (timer) {
clearTimeout(timer);
timer = 0;
reject();
reject = null;
}
}
};
};
Live Example:
const later = (delay, value) => {_x000D_
let timer = 0;_x000D_
let reject = null;_x000D_
const promise = new Promise((resolve, _reject) => {_x000D_

Usually you'll have a promise library (one you write yourself, or one of the several out there). That library will usually have an object that you can create and later "resolve," and that object will have a "promise" you can get from it.
Then later
would tend to look something like this:
function later() {
var p = new PromiseThingy();
setTimeout(function() {
p.resolve();
}, 2000);
return p.promise(); // Note we're not returning `p` directly
}
In a comment on the question, I asked:
Are you trying to create your own promise library?
and you said
I wasn't but I guess now that's actually what I was trying to understand. That how a library would do it
To aid that understanding, here's a very very basic example, which isn't remotely Promises-A compliant: Live Copy
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Very basic promises</title>
</head>
<body>
<script>
(function() {
// ==== Very basic promise implementation, not remotely Promises-A compliant, just a very basic example
var PromiseThingy = (function() {
// Internal - trigger a callback
function triggerCallback(callback, promise) {
try {
callback(promise.resolvedValue);
}
catch (e) {
}
}
// The internal promise constructor, we don't share this
function Promise() {
this.callbacks = [];
}
// Register a 'then' callback
Promise.prototype.then = function(callback) {
var thispromise = this;
if (!this.resolved) {
// Not resolved yet, remember the callback
this.callbacks.push(callback);
}
else {
// Resolved; trigger callback right away, but always async
setTimeout(function() {
triggerCallback(callback, thispromise);
}, 0);
}
return this;
};
// Our public constructor for PromiseThingys
function PromiseThingy() {
this.p = new Promise();
}
// Resolve our underlying promise
PromiseThingy.prototype.resolve = function(value) {
var n;
if (!this.p.resolved) {
this.p.resolved = true;
this.p.resolvedValue = value;
for (n = 0; n < this.p.callbacks.length; ++n) {
triggerCallback(this.p.callbacks[n], this.p);
}
}
};
// Get our underlying promise
PromiseThingy.prototype.promise = function() {
return this.p;
};
// Export public
return PromiseThingy;
})();
// ==== Using it
function later() {
var p = new PromiseThingy();
setTimeout(function() {
p.resolve();
}, 2000);
return p.promise(); // Note we're not returning `p` directly
}
display("Start " + Date.now());
later().then(function() {
display("Done1 " + Date.now());
}).then(function() {
display("Done2 " + Date.now());
});
function display(msg) {
var p = document.createElement('p');
p.innerHTML = String(msg);
document.body.appendChild(p);
}
})();
</script>

You can try defining a constant in index.php
and add something like
if (!defined("YOUR_CONSTANT")) die('No direct access');
to the beginning of the other files.
OR, you can use mod_rewrite
and redirect requests to index.php, editing .htaccess
like this:
RewriteEngine on
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ /index.php/$1 [L,R=301]
Then you should be able to analyze all incoming requests in the index.php and take according actions.
If you want to leave out all *.jpg, *.gif, *.css and *.png files, for example, then you should edit second line like this:
RewriteCond $1 !^(index\.php|*\.jpg|*\.gif|*\.css|*\.png)
As has been mentioned, as of PHP 5.6+ you can (should!) use the ...
token (aka "splat operator", part of the variadic functions functionality) to easily call a function with an array of arguments:
<?php
function variadic($arg1, $arg2)
{
// Do stuff
echo $arg1.' '.$arg2;
}
$array = ['Hello', 'World'];
// 'Splat' the $array in the function call
variadic(...$array);
// 'Hello World'
Note: array items are mapped to arguments by their position in the array, not their keys.
As per CarlosCarucce's comment, this form of argument unpacking is the fastest method by far in all cases. In some comparisons, it's over 5x faster than call_user_func_array
.
Because I think this is really useful (though not directly related to the question): you can type-hint the splat operator parameter in your function definition to make sure all of the passed values match a specific type.
(Just remember that doing this it MUST be the last parameter you define and that it bundles all parameters passed to the function into the array.)
This is great for making sure an array contains items of a specific type:
<?php
// Define the function...
function variadic($var, SomeClass ...$items)
{
// $items will be an array of objects of type `SomeClass`
}
// Then you can call...
variadic('Hello', new SomeClass, new SomeClass);
// or even splat both ways
$items = [
new SomeClass,
new SomeClass,
];
variadic('Hello', ...$items);
If you already know the key, you can directly update the value at that key using m[key] = new_value
Here is a sample code that might help:
map<int, int> m;
for(int i=0; i<5; i++)
m[i] = i;
for(auto it=m.begin(); it!=m.end(); it++)
cout<<it->second<<" ";
//Output: 0 1 2 3 4
m[4] = 7; //updating value at key 4 here
cout<<"\n"; //Change line
for(auto it=m.begin(); it!=m.end(); it++)
cout<<it->second<<" ";
// Output: 0 1 2 3 7
It needs to be done as following:
getScrollView().post(new Runnable() {
@Override
public void run() {
getScrollView().fullScroll(ScrollView.FOCUS_DOWN);
}
});
This way the view is first updated and then scrolls to the "new" bottom.

I solved this, without having to completely reinstall Visual Studio 2013.
For those who may come across this in the future, the following steps worked for me:
vs_professional.exe
).If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3
Click the link for 'examine the log file' and look near the bottom of the log, for this line:
open regedit.exe
and do an Edit > Find...
for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
. This was found in:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
Edit the BundleVersion
value and change it to a lower version. I changed mine from 12.0.21005.13
to 12.0.21000.13
:
Exit the registry
Run the ISO (or vs_professional.exe
) again. If it has a repair button like the image below, you can skip to step 4.
Run the ISO (or vs_professional.exe
) again. This time repair should be visible.
Click Repair
and let it update your installation and apply its embedded license key. This took about 20 minutes.
Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product
:
Hope this helps somebody in the future!
-fix- because you want to change from radians to degrees, it is actually rad=deg * math.pi /180 and not deg*180/math.pi
import math
x=1 # in deg
x = x*math.pi/180 # convert to rad
y = math.cos(x) # calculate in rad
print y
in 1 line it can be like this
y=math.cos(1*math.pi/180)
I had the same problem and I solved it like this, by taking the original data frame without row names and adding them later
SFIo <- as.matrix(apply(SFI[,-1],2,as.numeric))
row.names(SFIo) <- SFI[,1]
I tried the solutions above and it looks like on rails 5.* the second agument by default is the value of the input form, what worked for me was:
text_field_tag :attr, "", placeholder: "placeholder text"
Rails has its own names. See them with:
rake time:zones:us
You can also run rake time:zones:all
for all time zones.
To see more zone-related rake tasks: rake -D time
So, to convert to EST, catering for DST automatically:
Time.now.in_time_zone("Eastern Time (US & Canada)")
You can use Integer.parseInt(str)
and catch the NumberFormatException
if the string is not a valid integer, in the following fashion (as pointed out by all answers):
static boolean isInt(String s)
{
try
{ int i = Integer.parseInt(s); return true; }
catch(NumberFormatException er)
{ return false; }
}
However, note here that if the evaluated integer overflows, the same exception will be thrown. Your purpose was to find out whether or not, it was a valid integer. So its safer to make your own method to check for validity:
static boolean isInt(String s) // assuming integer is in decimal number system
{
for(int a=0;a<s.length();a++)
{
if(a==0 && s.charAt(a) == '-') continue;
if( !Character.isDigit(s.charAt(a)) ) return false;
}
return true;
}
It depends on how you want the text to display. If you want it all to be left-aligned then either format it as in the first snippet or iterate through the lines left-trimming all the space.
Just like any other environment variable, with SET
:
SET PATH=%PATH%;c:\whatever\else
If you want to have a little safety check built in first, check to see if the new path exists first:
IF EXIST c:\whatever\else SET PATH=%PATH%;c:\whatever\else
If you want that to be local to that batch file, use setlocal
:
setlocal
set PATH=...
set OTHERTHING=...
@REM Rest of your script
Read the docs carefully for setlocal
/endlocal
, and have a look at the other references on that site - Functions is pretty interesting too and the syntax is tricky.
The Syntax page should get you started with the basics.
The problem I had was related to SOAP version. The asmx
service was configured to accept both versions, 1.1 and 1.2, so, I think that when you are consuming the service, the client or the server doesn't know what version resolve.
To fix that, is necessary add:
using (wsWebService yourService = new wsWebService())
{
yourService.Url = "https://myUrlService.com/wsWebService.asmx?op=someOption";
yourService.UseDefaultCredentials = true; // this line depends on your authentication type
yourService.SoapVersion = SoapProtocolVersion.Soap11; // asign the version of SOAP
var result = yourService.SomeMethod("Parameter");
}
Where wsWebService
is the name of the class generated as a reference.
If it doesn't show up in your package manager (i.e. apt-cache search texinfo
) and even apt-file search bin/makeinfo
is no help, you may have to enable non-free/restricted packages for your package manager.
For ubuntu, sudo $EDITOR /etc/apt/sources.list
and add restricted
.
deb http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-security main
deb http://archive.ubuntu.com/ubuntu bionic-updates main
For debian, sudo $EDITOR /etc/apt/sources.list
and add non-free
. You can even have preferences on package level if you don't want to clutter the package db with non-free stuff.
After a sudo apt-get udpate
you should find the required package.
There have been a slew of recent changes in this arena, so I thought a fresh answer would be helpful.

I installed pip3
using
python3.7 -m pip install pip
But upon using pip3
to install other dependencies, it was using python3.6.
You can check the by typing pip3 --version
Hence, I used pip3
like this (stated in one of the above answers):
python3.7 -m pip install <module>
or use it like this:
python3.7 -m pip install -r requirements.txt
I made a bash alias for later use in ~/.bashrc file as alias pip3='python3.7 -m pip'
. If you use alias, don't forget to source ~/.bashrc
after making the changes and saving it.
Add this code
runOnUiThread(new Runnable() { public void run() {
adapter = new CustomAdapter(anotherdata);
adapter.notifyDataSetChanged();
}
});
There is small function, it allow to use construction like [1, 2].range(3, 4) -> [1, 2, 3, 4] also it works with negative params. Enjoy.
Array.prototype.range = function(from, to)
{
var range = (!to)? from : Math.abs(to - from) + 1, increase = from < to;
var tmp = Array.apply(this, {"length": range}).map(function()
{
return (increase)?from++ : from--;
}, Number);
return this.concat(tmp);
};
Following up @Tim Mahy - There's two possible ways to feed SqlBulkCopy: a DataReader or via DataTable. Here the code for DataTable:
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Id", typeof(string)));
dt.Columns.Add(new DataColumn("Name", typeof(string)));
foreach (Entry entry in entries)
dt.Rows.Add(new string[] { entry.Id, entry.Name });
using (SqlBulkCopy bc = new SqlBulkCopy(connection))
{ // the following 3 lines might not be neccessary
bc.DestinationTableName = "Entries";
bc.ColumnMappings.Add("Id", "Id");
bc.ColumnMappings.Add("Name", "Name");
bc.WriteToServer(dt);
}

index
and find
Next to the find
method there is as well index
. find
and index
both yield the same result: returning the position of the first occurrence, but if nothing is found index
will raise a ValueError
whereas find
returns -1
. Speedwise, both have the same benchmark results.
s.find(t) #returns: -1, or index where t starts in s
s.index(t) #returns: Same as find, but raises ValueError if t is not in s
rfind
and rindex
:In general, find and index return the smallest index where the passed-in string starts, and
rfind
andrindex
return the largest index where it starts Most of the string searching algorithms search from left to right, so functions starting withr
indicate that the search happens from right to left.
So in case that the likelihood of the element you are searching is close to the end than to the start of the list, rfind
or rindex
would be faster.
s.rfind(t) #returns: Same as find, but searched right to left
s.rindex(t) #returns: Same as index, but searches right to left

I'm presuming you are actually using sqlite3 even though your code says otherwise. Here are some things to check:
$ fuser cache.db
should say nothing)$ sqlite3 cache.db "pragma integrity_check;"
$ sqlite3 cache.db ".backup cache.db.bak"
$ sqlite3 cache.db.bak ".schema"
Failing that, read Things That Can Go Wrong and How to Corrupt Your Database Files
And if you don't want R to add decimals or zeros, you can stop it from drawing the x axis or the y axis or both using ...axt. Then, you can add your own ticks and labels:
plot(x, y, xaxt="n")
plot(x, y, yaxt="n")
axis(1 or 2, at=c(1, 5, 10), labels=c("First", "Second", "Third"))
With gawk, you can use the match
function to capture parenthesized groups.
gawk 'match($0, pattern, ary) {print ary[1]}'
example:
echo "abcdef" | gawk 'match($0, /b(.*)e/, a) {print a[1]}'
outputs cd
.
Note the specific use of gawk which implements the feature in question.
For a portable alternative you can achieve similar results with match()
and substr
.
example:
echo "abcdef" | awk 'match($0, /b[^e]*/) {print substr($0, RSTART+1, RLENGTH-1)}'
outputs cd
.
The "accepted" answer to this question is both incorrect and myopic.
It is incorrect in that it will match strings like 0001
, which is not a valid year.
It is myopic in that it will not match any values above 9999. Have we already forgotten the lessons of Y2K? Instead, use the regular expression:
^[1-9]\d{3,}$
If you need to match years in the past, in addition to years in the future, you could use this regular expression to match any positive integer:
^[1-9]\d*$
Even if you don't expect dates from the past, you may want to use this regular expression anyway, just in case someone invents a time machine and wants to take your software back with them.
Note: This regular expression will match all years, including those before the year 1, since they are typically represented with a BC designation instead of a negative integer. Of course, this convention could change over the next few millennia, so your best option is to match any integer—positive or negative—with the following regular expression:
^-?[1-9]\d*$
Recently I have read a Java SE 8 Programmer Guide ii Book.
I found something about the difference between AutoCloseable
vs Closeable
.
The AutoCloseable
interface was introduced in Java 7. Before that, another interface
existed called Closeable
. It was similar to what the language designers wanted, with the
following exceptions:
Closeable
restricts the type of exception thrown to IOException
.Closeable
requires implementations to be idempotent.The language designers emphasize backward compatibility. Since changing the existing
interface was undesirable, they made a new one called AutoCloseable
. This new
interface is less strict than Closeable
. Since Closeable
meets the requirements for
AutoCloseable
, it started implementing AutoCloseable
when the latter was introduced.
"the origin is at the top-left of the screen and the Y-Coordinate increases going down, while the X-Coordinate increases to the right like normal. I guess my question becomes, do I have to convert the screen coordinates to Cartesian coordinates before applying the above formula?"
If you were calculating the angle using Cartesian coordinates, and both points were in quadrant 1 (where x>0 and y>0), the situation would be identical to screen pixel coordinates (except for the upside-down-Y thing. If you negate Y to get it right-side up, it becomes quadrant 4...). Converting screen pixel coordinates to Cartesian doesnt really change the angle.
As stated in the answer, in order to use a non deprecated way to sign your own script, one should use New-SelfSignedCertificate.
New-SelfSignedCertificate -DnsName [email protected] -Type CodeSigning -CertStoreLocation cert:\CurrentUser\My
Export-Certificate -Cert (Get-ChildItem Cert:\CurrentUser\My -CodeSigningCert)[0] -FilePath code_signing.crt
The [0] will make this work for cases when you have more than one certificate... Obviously make the index match the certificate you want to use... or use a way to filtrate (by thumprint or issuer).
Import-Certificate -FilePath .\code_signing.crt -Cert Cert:\CurrentUser\TrustedPublisher
Import-Certificate -FilePath .\code_signing.crt -Cert Cert:\CurrentUser\Root
Set-AuthenticodeSignature .\script.ps1 -Certificate (Get-ChildItem Cert:\CurrentUser\My -CodeSigningCert)
Obviously once you have setup the key, you can simply sign any other scripts with it.
You can get more detailed information and some troubleshooting help in this article.
It is also possible to do it with an embedded web browser, note however that since this might be a local file, and also because it is not actually the browser directly and there is no DOM so there is no ready state.
Here is the code for the approach I worked out on a win form web browser control:
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Navigate(@"path\to\file");
}
private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
//Progress Changed fires multiple times, however after the Navigated event it is fired only once,
//and at this point it is ready to print
webBrowser1.ProgressChanged += (o, args) =>
{
webBrowser1.Print();//Note this does not print only brings up the print preview dialog
//Should be on a separate task to ensure the main thread
//can fully initialize the print dialog
Task.Factory.StartNew(() =>
{
Thread.Sleep(1000);//We need to wait before we can send enter
//This assumes that the print preview is still in focus
Action g = () =>
{
SendKeys.SendWait("{ENTER}");
};
this.Invoke(g);
});

HTTP status code 500 usually means that the webserver code has crashed. You need to determine the status code beforehand using HttpURLConnection#getResponseCode()
and in case of errors, read the HttpURLConnection#getErrorStream()
instead. It may namely contain information about the problem.
If the host has blocked you, you would rather have gotten a 4nn status code like 401 or 403.
Happy coding!

You need to use HttpWebRequest
rather than WebClient
as you can't set the timeout on WebClient
without extending it (even though it uses the HttpWebRequest
). Using the HttpWebRequest
instead will allow you to set the timeout.
Change Below line
if (str == null | str.length() == 0) {
into
if (str == null || str.isEmpty()) {
now your code will run corectlly. Make sure str.isEmpty()
comes after str == null
because calling isEmpty()
on null will cause NullPointerException
. Because of Java uses Short-circuit evaluation when str == null
is true it will not evaluate str.isEmpty()
To add new ViewController
once you have have an existing ViewController
, follow below step:
Click on background of Main.storyboard
.
Search and select ViewController
from object library at the
utility window.
Drag and drop it in background to create a new ViewController
.
Just go through the string, building up an int as usual, but ignore non-number characters:
int res = 0;
for (int i=0; i < str.length(); i++) {
char c = s.charAt(i);
if (c < '0' || c > '9') continue;
res = res * 10 + (c - '0');
}
In PowerShell, boolean parameters can be declared by mentioning their type before their variable.
function GetWeb() {
param([bool] $includeTags)
........
........
}
You can assign value by passing $true | $false
GetWeb -includeTags $true
And if you add an alias for it then it's even better right?
git config --global alias.nccommit 'commit -a --allow-empty-message -m ""'
Now you just do an nccommit, nc because of no comment, and everything should be commited.
You could try:
export ENVVAR=value
in virtualenv_root/bin/activate. Basically the activate script is what is executed when you start using the virtualenv so you can put all your customization in there.
I'll answer your question with an example. Suppose we had a Math class with a static method add. You would call this method like so:
Math.add(2, 3);
If Math were an interface instead of a class, it could not have any defined functions. As such, saying something like Math.add(2, 3) makes no sense.
public static T Runner<T>(Func<T> funcToRun)
{
//Do stuff before running function as normal
return funcToRun();
}
Usage:
var ReturnValue = Runner(() => GetUser(99));
It's not implemented in C++. (also, char*
strings? I hope not).
Usually if you have so many parameters it is a fairly serious code smell. But instead, why not simply value-initialize the struct and then assign each member?
The first answer is correct but you say that you are using cv2 which inherently uses numpy arrays. So, to make a complete different copy of say "myImage":
newImage = myImage.copy()
The above is enough. No need to import numpy.
It seems that the extension cannot be found anymore using "Visual Studio Team Services". Instead, by following the link in Using Visual Studio Code & Team Foundation Version Control on "Get the TFVC plugin working in Visual Studio Code" you get to the Azure Repos Extension for Visual Studio Code GitHub. There it is explained that you now have to look for "Team Azure Repos".
Also, please note, that with the new Settings editor in Visual Studio Code the additional slashes do not have to be added. The path to tf.exe for VS 2017 - if specified using the "user friendly" Settings editor - would be just
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe
It is specific from your driver. You need to supply a parameter in your Java program to tell it the time zone you want to use.
java -Duser.timezone="America/New_York" GetCurrentDateTimeZone
Further this:
to_char(new_time(sched_start_time, 'CURRENT_TIMEZONE', 'NEW_TIMEZONE'), 'MM/DD/YY HH:MI AM')
May also be of value in handling the conversion properly. Taken from here
it depends on how you trigger the event. the key you are looking is textbox.clientid.
x.aspx code
<script type="text/javascript">
function disable_textbox(tid) {
var mytextbox = document.getElementById(tid);
mytextbox.disabled=false
}
</script>
code behind x.aspx.cs
string frameScript = "<script language='javascript'>" + "disable_textbox(" + tx.ClientID ");</script>";
Page.ClientScript.RegisterStartupScript(Page.GetType(), "FrameScript", frameScript);
This is a bit more readable:
Object[] allValues = all.getDeclaringClass().getEnumConstants();
Both commands are correct
php_value post_max_size 30M
php_value upload_max_filesize 30M
BUT to use the .htaccess
you have to enable rewrite_module

find this line:
# LoadModule rewrite_module modules/mod_rewrite.so

The smallest one I know is lighttpd.
Security, speed, compliance, and flexibility -- all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems. And best of all it's Open Source licensed under the revised BSD license.
Edit: removed Windows version link, now a spam/malware plugin site.
what about this?
$(this).mouseleave(function(){
var thisUI = $(this);
$('html').click(function(){
thisUI.hide();
$('html').unbind('click');
});
});
If you have previously run mvn install on project B it will have been installed to your local repository, so when you build package A Maven can resolve the dependency. So as long as you install project B each time you change it your builds for project A will be up to date.
You can define a multi-module project with an aggregator pom to build a set of projects.
It's also worthwhile mentioning m2eclipse, it integrates Maven into Eclipse and allows you to (optionally) resolve dependencies from the workspace. So if you are hacking away on multiple projects, the workspace content will be used for compilation. Once you are happy with your changes, run mvn install (on each project in turn, or using an aggregator) to put them in your local repository.
For me, I tried manage app execution aliases
and got an error that python3 is not a command so for that, I used py
instead of python3
and it worked
I don't know why this is happening but It worked for me
Add this code inside your input tag
<?php if ($tag_1 == 'yes') echo "checked='checked'"; ?>
You could create a patch from the commits that you want to copy and apply the patch to the destination branch.
you can create an array that filled with your object fields and use an index on the array and access object properties via that
propertiesName:['pr1','pr2','pr3']
this.myObject[this.propertiesName[0]]
In my situation, I didn't have the full vendor dependencies in place (composer file was messed up during original install) - so running any artisan commands caused a failure.
I was able to use the --no-scripts
flag to prevent artisan from executing before it was included. Once my dependencies were in place, everything worked as expected.
composer update --no-scripts
Short and simple. I have not tested in javascript code yet but It looks it will work:

Here's my example in which I work
round(value,significantDigit)
is the ordinary solution, however this does not operate as one would expect from a math perspective when round values ending in 5
. If the 5
is in the digit just after the one you're rounded to, these values are only sometimes rounded up as expected (i.e. 8.005
rounding to two decimal digits gives 8.01
). For certain values due to the quirks of floating point math, they are rounded down instead!
i.e.
>>> round(1.0005,3)
1.0
>>> round(2.0005,3)
2.001
>>> round(3.0005,3)
3.001
>>> round(4.0005,3)
4.0
>>> round(1.005,2)
1.0
>>> round(5.005,2)
5.0
>>> round(6.005,2)
6.0
>>> round(7.005,2)
7.0
>>> round(3.005,2)
3.0
>>> round(8.005,2)
8.01
Weird.
Assuming your intent is to do the traditional rounding for statistics in the sciences, this is a handy wrapper to get the round
function working as expected needing to import
extra stuff like Decimal
.
>>> round(0.075,2)
0.07
>>> round(0.075+10**(-2*5),2)
0.08
Aha! So based on this we can make a function...
def roundTraditional(val,digits):
return round(val+10**(-len(str(val))-1), digits)
Basically this adds a value guaranteed to be smaller than the least given digit of the string you're trying to use round
on. By adding that small quantity it preserve's round
's behavior in most cases, while now ensuring if the digit inferior to the one being rounded to is 5
it rounds up, and if it is 4
it rounds down.
The approach of using 10**(-len(val)-1)
was deliberate, as it the largest small number you can add to force the shift, while also ensuring that the value you add never changes the rounding even if the decimal .
is missing. I could use just 10**(-len(val))
with a condiditional if (val>1)
to subtract 1
more... but it's simpler to just always subtract the 1
as that won't change much the applicable range of decimal numbers this workaround can properly handle. This approach will fail if your values reaches the limits of the type, this will fail, but for nearly the entire range of valid decimal values it should work.
You can also use the decimal library to accomplish this, but the wrapper I propose is simpler and may be preferred in some cases.
Edit: Thanks Blckknght for pointing out that the 5
fringe case occurs only for certain values. Also an earlier version of this answer wasn't explicit enough that the odd rounding behavior occurs only when the digit immediately inferior to the digit you're rounding to has a 5
.
There's a bit of a hack for this, since the HTML5 canvas is required to parse color values when certain properties like strokeStyle
and fillStyle
are set:
var ctx = document.createElement('canvas').getContext('2d');
ctx.strokeStyle = 'rgb(64, 128, 192)';
var hexColor = ctx.strokeStyle;
Just to add to what's already here, use the following:
background: -moz-linear-gradient(rgba(0,0,0,.7),rgba(0,0,0,.7));
background: -webkit-linear-gradient(rgba(0,0,0,.7),rgba(0,0,0,.7));
background: linear-gradient(rgba(0,0,0,.7),rgba(0,0,0,.7));
filter: unquote("progid:DXImageTransform.Microsoft.gradient( startColorstr='#b3000000', endColorstr='#b3000000',GradientType=0 )");
...for cross-browser support of a 70% linear-gradient overlay. To brighten the image, you can change all those 0,0,0
's into 255,255,255
's. If 70% is a bit much, go ahead and change the .7
. And, for future reference check out this: http://www.colorzilla.com/gradient-editor/
You can add the plugins as suggested by @Vikramaditya. Then to generate the production build. You have to run the the command
NODE_ENV=production webpack --config ./webpack.production.config.js
If using babel
, you will also need to prefix BABEL_ENV=node
to the above command.
Here is a function that works for any floating-point type, not just double
, and also puts the stream back the way it was found afterwards. Unfortunately it won't interact well with threads, but that's the nature of iostreams. You'll need these includes at the start of your file:
#include <limits>
#include <iostream>
Here's the function, you could it in a header file if you use it a lot:
template <class T>
void printVal(std::ostream& os, T val)
{
auto oldFlags = os.flags();
auto oldPrecision = os.precision();
os.flags(oldFlags & ~std::ios_base::floatfield);
os.precision(std::numeric_limits<T>::digits10);
os << val;
os.flags(oldFlags);
os.precision(oldPrecision);
}
Use it like this:
double d = foo();
float f = bar();
printVal(std::cout, d);
printVal(std::cout, f);
If you want to be able to use the normal insertion <<
operator, you can use this extra wrapper code:
template <class T>
struct PrintValWrapper { T val; };
template <class T>
std::ostream& operator<<(std::ostream& os, PrintValWrapper<T> pvw) {
printVal(os, pvw.val);
return os;
}
template <class T>
PrintValWrapper<T> printIt(T val) {
return PrintValWrapper<T>{val};
}
Now you can use it like this:
double d = foo();
float f = bar();
std::cout << "The values are: " << printIt(d) << ", " << printIt(f) << '\n';
If you are interested in portability between different SQL servers you should use ANSI SQL queries. String escaping in ANSI SQL is done by using double quotes ("). Unfortunately, this escaping method is not portable to MySQL, unless it is set in ANSI compatibility mode.
Personally, I always start my MySQL server with the --sql-mode='ANSI' argument since this allows for both methods for escaping. If you are writing queries that are going to be executed in a MySQL server that was not setup / is controlled by you, here is what you can do:
Enclose them in the following MySQL specific queries:
SET @OLD_SQL_MODE=@@SQL_MODE;
SET SESSION SQL_MODE='ANSI';
-- ANSI SQL queries
SET SESSION SQL_MODE=@OLD_SQL_MODE;
This way the only MySQL specific queries are at the beginning and the end of your .sql script. If you what to ship them for a different server just remove these 3 queries and you're all set. Even more conveniently you could create a script named: script_mysql.sql that would contain the above mode setting queries, source a script_ansi.sql script and reset the mode.
I fixed this issue as adding Dynamic Web Module to Project Facets
You could also write it a little more cleaner using updateOne & $set, plus async/await.
const updateUser = async (newUser) => {
try {
await User.updateOne({ username: oldUsername }, {
$set: {
username: newUser.username,
password: newUser.password,
rights: newUser.rights
}
})
} catch (err) {
console.log(err)
}
}
Since you don't need the resulting document, you can just use updateOne instead of findOneAndUpdate.
Here's a good discussion about the difference: MongoDB 3.2 - Use cases for updateOne over findOneAndUpdate
Abstraction - is the process (and result of this process) of identifying the common essential characteristics for a set of objects. One might say that Abstraction is the process of generalization: all objects under consideration are included in a superset of objects, all of which possess given properties (but are different in other respects).
Encapsulation - is the process of enclosing data and functions manipulating this data into a single unit, so that to hide the internal implementation from the outside world.
This is a general answer not related to a specific programming language (as was the question). So the answer is: abstraction and encapsulation have nothing in common. But their implementations might relate to each other (say, in Java: Encapsulation - details are hidden in a class, Abstraction - details are not present at all in a class or interface).
PostgreSQL allows partial indexes, where only rows that match a predicate are indexed. For instance, you might want to index the customer table for only those records which are active. This might look something like:
create index i on customers (id, name, whatever) where is_active is true;
If your index many columns, and you have many inactive customers, this can be a big win in terms of space (the index will be stored in fewer disk pages) and thus performance. To hit the index you need to, at a minimum, specify the predicate:
select name from customers where is_active is true;
It must works at page load and when an script tag is added with javascript (ex. with ajax)
<script id="currentScript">
var $this = document.getElementById("currentScript");
$this.setAttribute("id","");
//...
</script>

SQLyog is GUI based solution to the problem of data search across all columns, tables and databases. One can customize search restricting it to field, table and databases.
In its Data Search
feature one can search for strings just like one uses Google.
This caused me huge headaches trying to implement such a grid for an application of ours. I tried all the various techniques out there but they each had problems. The closest I came was using a jQuery plugin such as Flexigrid (look on http://www.ajaxrain.com for alternatives), but this doesn't seem to support 100% wide tables which is what I needed.
What I ended up doing was rolling my own; Firefox supports scrolling tbody
elements so I browser sniffed and used appropriate CSS (setting height, overflow etc... ask if you want more details) to make that scroll, and then for other browsers I used two separate tables set to use table-layout: fixed
which uses a sizing algorithm that is guarenteed not to overflow the stated size (normal tables will expand when content is too wide to fit). By giving both tables identical widths I was able to get their columns to line up. I wrapped the second one in a div set to scroll and with a bit of jiggery pokery with margins etc managed to get the look and feel I wanted.
Sorry if this answer sounds a bit vague in places; I'm writing quickly as I don't have much time. Leave a comment if you want me to expand any further!
I'm a little surprised that this question has been asked so many times before, but the most reuseable and friendly solution hasn't been documented.
I often have webpages using AngularJS, and when I click on a Save button, I'll "POST" this data back to my .aspx page or .ashx handler to save this back to the database. The data will be in the form of a JSON record.
On the server, to turn the raw posted data back into a C# class, here's what I would do.
First, define a C# class which will contain the posted data.
Supposing my webpage is posting JSON data like this:
{
"UserID" : 1,
"FirstName" : "Mike",
"LastName" : "Mike",
"Address1" : "10 Really Street",
"Address2" : "London"
}
Then I'd define a C# class like this...
public class JSONRequest
{
public int UserID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
}
(These classes can be nested, but the structure must match the format of the JSON data. So, if you're posting a JSON User record, with a list of Order records within it, your C# class should also contain a List<>
of Order records.)
Now, in my .aspx.cs or .ashx file, I just need to do this, and leave JSON.Net to do the hard work...
protected void Page_Load(object sender, EventArgs e)
{
string jsonString = "";
HttpContext.Current.Request.InputStream.Position = 0;
using (StreamReader inputStream = new StreamReader(this.Request.InputStream))
{
jsonString = inputStream.ReadToEnd();
}
JSONRequest oneQuestion = JsonConvert.DeserializeObject<JSONRequest>(jsonString);
And that's it. You now have a JSONRequest
class containing the various fields which were POSTed to your server.
Since pip is a package,
pip uninstall pip
Will do it.
EDIT: If that does not work, try sudo -H pip uninstall pip
.
Cross join :Cross Joins produce results that consist of every combination of rows from two or more tables. That means if table A has 3 rows and table B has 2 rows, a CROSS JOIN will result in 6 rows. There is no relationship established between the two tables – you literally just produce every possible combination.
Full outer Join : A FULL OUTER JOIN is neither "left" nor "right"— it's both! It includes all the rows from both of the tables or result sets participating in the JOIN. When no matching rows exist for rows on the "left" side of the JOIN, you see Null values from the result set on the "right." Conversely, when no matching rows exist for rows on the "right" side of the JOIN, you see Null values from the result set on the "left."
Just in case you're using bootstrap 4, you can add px-0
(set left/right padding to 0) and mx-0
(set left/right margin to 0) CSS class to body tag, like below:
<body class="px-0; mx-0">
<!--your body HTML-->
</body>
appHelper.validateDates = function (start, end) {
var returnval = false;
var fd = new Date(start);
var fdms = fd.getTime();
var ed = new Date(end);
var edms = ed.getTime();
var cd = new Date();
var cdms = cd.getTime();
if (fdms >= edms) {
returnval = false;
console.log("step 1");
}
else if (cdms >= edms) {
returnval = false;
console.log("step 2");
}
else {
returnval = true;
console.log("step 3");
}
console.log("vall", returnval)
return returnval;
}
There is a problem. When milliseconds is 59999, actually it is 1 minute but it will be computed as 59 seconds and 999 milliseconds is lost.
Here is a modified version based on previous answers, which can solve this loss:
public static String formatTime(long millis) {
long seconds = Math.round((double) millis / 1000);
long hours = TimeUnit.SECONDS.toHours(seconds);
if (hours > 0)
seconds -= TimeUnit.HOURS.toSeconds(hours);
long minutes = seconds > 0 ? TimeUnit.SECONDS.toMinutes(seconds) : 0;
if (minutes > 0)
seconds -= TimeUnit.MINUTES.toSeconds(minutes);
return hours > 0 ? String.format("%02d:%02d:%02d", hours, minutes, seconds) : String.format("%02d:%02d", minutes, seconds);
}
You can run the cd
and the executable in a subshell by enclosing the command line in a pair of parentheses:
(cd SOME_PATH && exec_some_command)
Demo:
$ pwd
/home/abhijit
$ (cd /tmp && pwd) # directory changed in the subshell
/tmp
$ pwd # parent shell's pwd is still the same
/home/abhijit
With an OR
(||) operation, if any one of the conditions are true, the result is true.
I think you want an AND
(&&) operation here.
You can use the JDOM library in Java. Define your tags as Element objects, document your elements with Document Class, and build your xml file with SAXBuilder. Try this example:
//Root Element
Element root=new Element("CONFIGURATION");
Document doc=new Document();
//Element 1
Element child1=new Element("BROWSER");
//Element 1 Content
child1.addContent("chrome");
//Element 2
Element child2=new Element("BASE");
//Element 2 Content
child2.addContent("http:fut");
//Element 3
Element child3=new Element("EMPLOYEE");
//Element 3 --> In this case this element has another element with Content
child3.addContent(new Element("EMP_NAME").addContent("Anhorn, Irene"));
//Add it in the root Element
root.addContent(child1);
root.addContent(child2);
root.addContent(child3);
//Define root element like root
doc.setRootElement(root);
//Create the XML
XMLOutputter outter=new XMLOutputter();
outter.setFormat(Format.getPrettyFormat());
outter.output(doc, new FileWriter(new File("myxml.xml")));
The ASCII value of Space
is 32. So you can compare your char to the octal value of 32 which is 40 or its hexadecimal value which is 20.
if(c == '\40')
{ ... }
or
if(c == '\x20')
{ ... }
Any number after the \
is assumed to be octal, if the character just after \
is not x
, in which case it is considered to be a hexadecimal.
if(sender is TextBox) {
var text = (sender as TextBox).Text;
}
When you use
this.getClass().getResource("myFile.ext")
getResource
will try to find the resource relative to the package.
If you use:
this.getClass().getResource("/myFile.ext")
getResource
will treat it as an absolute path and simply call the classloader like you would have if you'd done.
this.getClass().getClassLoader().getResource("myFile.ext")
The reason you can't use a leading /
in the ClassLoader
path is because all ClassLoader
paths are absolute and so /
is not a valid first character in the path.
In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice]
.
Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as...
at the top of the menu.
Updated 2016-04-19: As of now, this also works for Sublime Text 3.
I would put my form into the markup and not into some data tag. This is how it could work:
$('#popover').popover({
html : true,
title: function() {
return $("#popover-head").html();
},
content: function() {
return $("#popover-content").html();
}
});
<a href="#" id="popover">the popover link</a>
<div id="popover-head" class="hide">
some title
</div>
<div id="popover-content" class="hide">
<!-- MyForm -->
</div>
You might want to take a look at X-Editable. A library that allows you to create editable elements on your page based on popovers.
Mike Costello has released Bootstrap Web Components. This nifty library has a Popovers Component that lets you embed the form as markup:
<button id="popover-target" data-original-title="MyTitle" title="">Popover</button>
<bs-popover title="Popover with Title" for="popover-target">
<!-- MyForm -->
</bs-popover>
try this
$(this).parent().css("backgroundImage", "url('../images/r-srchbg_white.png') no-repeat");
You are mixing the 2 different CASE
syntaxes inappropriately.
Use this style (Searched)
CASE
WHEN u.nnmu ='0' THEN mu.naziv_mesta
WHEN u.nnmu ='1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
Or this style (Simple)
CASE u.nnmu
WHEN '0' THEN mu.naziv_mesta
WHEN '1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
Not This (Simple but with boolean search predicates)
CASE u.nnmu
WHEN u.nnmu ='0' THEN mu.naziv_mesta
WHEN u.nnmu ='1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
In MySQL this will end up testing whether u.nnmu
is equal to the value of the boolean expression u.nnmu ='0'
itself. Regardless of whether u.nnmu
is 1
or 0
the result of the case expression itself will be 1
For example if nmu = '0'
then (nnmu ='0'
) evaluates as true
(1) and (nnmu ='1'
) evaluates as false
(0). Substituting these into the case expression gives
SELECT CASE '0'
WHEN 1 THEN '0'
WHEN 0 THEN '1'
ELSE 'GRESKA'
END as mesto_utovara
if nmu = '1'
then (nnmu ='0'
) evaluates as false
(0) and (nnmu ='1'
) evaluates as true
(1). Substituting these into the case expression gives
SELECT CASE '1'
WHEN 0 THEN '0'

I got the solution by using comm
comm -23 file1 file2
will give you the desired output.
The files need to be sorted first anyway.
@salman khan what Usman Kurd suggested is perfect. Only thing i found which can be corrected is that "For google maps v2 we use LatLng class. So below is the code of Usman Kurd that can be used for Google Maps v2. I checked it works perfect.
public double CalculationByDistance(LatLng StartP, LatLng EndP) {
int Radius=6371;//radius of earth in Km
double lat1 = StartP.latitude;
double lat2 = EndP.latitude;
double lon1 = StartP.longitude;
double lon2 = EndP.longitude;
double dLat = Math.toRadians(lat2-lat1);
double dLon = Math.toRadians(lon2-lon1);
double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
Math.sin(dLon/2) * Math.sin(dLon/2);
double c = 2 * Math.asin(Math.sqrt(a));
double valueResult= Radius*c;
double km=valueResult/1;
DecimalFormat newFormat = new DecimalFormat("####");
int kmInDec = Integer.valueOf(newFormat.format(km));
double meter=valueResult%1000;
int meterInDec= Integer.valueOf(newFormat.format(meter));
Log.i("Radius Value",""+valueResult+" KM "+kmInDec+" Meter "+meterInDec);
return Radius * c;
}
