<?php
$url=parse_url("http://domain.com/site/gallery/1?user=12#photo45 ");
echo $url["fragment"]; //This variable contains the fragment
?>
This is should work
If you're doing this in Drupal and use the Form API to change the #type from text to 'hidden' in hook_form_alter (for example), be advised that the output HTML will have different (or omitted) DIV wrappers, IDs and class names.
Try:
mmatrix = np.zeros((nrows, ncols))
Since the shape parameter has to be an int or sequence of ints
http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html
Otherwise you are passing ncols
to np.zeros
as the dtype.
The git rev-parse
solution proposed by @Andy works fine if the date you're interested is the commit's date. If however you want to checkout based on the author's date, rev-parse
won't work, because it doesn't offer an option to use that date for selecting the commits. Instead, you can use the following.
git checkout $(
git log --reverse --author-date-order --pretty=format:'%ai %H' master |
awk '{hash = $4} $1 >= "2016-04-12" {print hash; exit 0 }
)
(If you also want to specify the time use $1 >= "2016-04-12" && $2 >= "11:37"
in the awk predicate.)
While the other answers are correct (int array values are by default initialized to 0), if you wanted to explicitly do so (say for example if you wanted an array filled with the value 42), you can use the fill() method of the Arrays class:
int [] myarray = new int[num_elts];
Arrays.fill(myarray, 42);
Or if you're a fan of 1-liners, you can use the Collections.nCopies()
routine:
Integer[] arr = Collections.nCopies(3, 42).toArray(new Integer[0]);
Would give arr the value:
[42, 42, 42]
(though it's Integer
, and not int
, if you need the primitive type you could defer to the Apache Commons ArrayUtils.toPrimitive()
routine:
int [] primarr = ArrayUtils.toPrimitive(arr);
CPUnit (http://cpunit.sourceforge.net) is a framework that is similar to Google Test, but which relies on less macos (asserts are functions), and where the macros are prefixed to avoid the usual macro pitfall. Tests look like:
#include <cpunit>
namespace MyAssetTest {
using namespace cpunit;
CPUNIT_FUNC(MyAssetTest, test_stuff) {
int some_value = 42;
assert_equals("Wrong value!", 666, some_value);
}
// Fixtures go as follows:
CPUNIT_SET_UP(MyAssetTest) {
// Setting up suite here...
// And the same goes for tear-down.
}
}
They auto-register, so you need not more than this. Then it is just compile and run. I find using this framework very much like using JUnit, for those who have had to spend some time programming Java. Very nice!
Using ToString("HH:mm")
certainly gives you what you want as a string.
If you want the current hour/minute as numbers, string manipulation isn't necessary; you can use the TimeOfDay
property:
TimeSpan timeOfDay = fechaHora.TimeOfDay;
int hour = timeOfDay.Hours;
int minute = timeOfDay.Minutes;
This is a late addition but I was looking for information on the scale function myself and though it might help somebody else as well.
To modify the response from Ricardo Saporta a little bit.
Scaling is not done using standard deviation, at least not in version 3.6.1 of R, I base this on "Becker, R. (2018). The new S language. CRC Press." and my own experimentation.
X.man.scaled <- X/sqrt(sum(X^2)/(length(X)-1))
X.aut.scaled <- scale(X, center = F)
The result of these rows are exactly the same, I show it without centering because of simplicity.
I would respond in a comment but did not have enough reputation.
An executor service can be used to manage multiple threads including status and completion. See http://programmingexamples.wikidot.com/executorservice
Just use com.google.common.io.Resources class. Example:
URL url = Resources.getResource("file name")
After that you have methods like: .getContent(), .getFile(), .getPath() etc
I've solved that problem.
Since readonly="readonly"
tag is not working (I've tried different browsers), you have to use disabled="disabled"
instead. But your checkbox's value will not post then...
Here is my solution:
To get "readonly" look and POST checkbox's value in the same time, just add a hidden "input" with the same name and value as your checkbox. You have to keep it next to your checkbox or between the same <form></form>
tags:
<input type="checkbox" checked="checked" disabled="disabled" name="Tests" value="4">SOME TEXT</input>
<input type="hidden" id="Tests" name="Tests" value="4" />
Also, just to let ya'll know readonly="readonly", readonly="true", readonly="",
or just READONLY
will NOT solve this! I've spent few hours to figure it out!
This reference is also NOT relevant (may be not yet, or not anymore, I have no idea): http://www.w3schools.com/tags/att_input_readonly.asp
You can also try to get the language from the document should might be your first port of call, then falling back to other means as often people will want their JS language to match the document language.
HTML5:
document.querySelector('html').getAttribute('lang')
Legacy:
document.querySelector('meta[http-equiv=content-language]').getAttribute('content')
No real source is necessarily 100% reliable as people can simply put in the wrong language.
There are language detection libraries that might let you determine the language by content.
You can use floating:
<div class="paragraphs">
<div class="row">
<div class="span4">
<img style="float:left" src="../site/img/success32.png"/>
<div class="content-heading"><h3>Experience   </h3></div>
<p style="clear:both">Donec id elit non mi porta gravida at eget metus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui.</p>
</div>
</div>
</div>
If you want the following <p>
to stay at the same line too, remove its
style="clear:both"
but then you should add
<div style="clear:both"></div>
after it.
Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.
First, click Slide Show > Set Up Show.
Put a checkmark to Loop continuously until 'Esc'.
Click Ok. Now, Click Slide Show > Custom Shows. Click New.
Select the slide you are looping, click Add. Click Ok and Close.
Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.
Right click on the thumbnail of the current slide, select Hide Slide.
Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"
This has worked for me.
It completely answered on basis of "generator" type in ID while storing any entity. If value for generator is "assigned" which means you are supplying the ID. Then it makes no diff in hibernate for save or persist. You can go with any method you want. If value is not "assigned" and you are using save() then you will get ID as return from the save() operation.
Another check is if you are performing the operation outside transaction limit or not. Because persist() belongs to JPA while save() for hibernate. So using persist() outside transaction boundaries will not allow to do so and throw exception related to persistant. while with save() no such restriction and one can go with DB transaction through save() outside the transaction limit.
The reference to the string is passed by value. There's a big difference between passing a reference by value and passing an object by reference. It's unfortunate that the word "reference" is used in both cases.
If you do pass the string reference by reference, it will work as you expect:
using System;
class Test
{
public static void Main()
{
string test = "before passing";
Console.WriteLine(test);
TestI(ref test);
Console.WriteLine(test);
}
public static void TestI(ref string test)
{
test = "after passing";
}
}
Now you need to distinguish between making changes to the object which a reference refers to, and making a change to a variable (such as a parameter) to let it refer to a different object. We can't make changes to a string because strings are immutable, but we can demonstrate it with a StringBuilder
instead:
using System;
using System.Text;
class Test
{
public static void Main()
{
StringBuilder test = new StringBuilder();
Console.WriteLine(test);
TestI(test);
Console.WriteLine(test);
}
public static void TestI(StringBuilder test)
{
// Note that we're not changing the value
// of the "test" parameter - we're changing
// the data in the object it's referring to
test.Append("changing");
}
}
See my article on parameter passing for more details.
There's some great information about this here: https://bugzilla.mozilla.org/show_bug.cgi?id=857142
Still experimenting but so far a minimally invasive solution, aimed only at FF is:

There is a library for this BarCode PHP. You just need to include a few files:
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
You can generate many types of barcodes, namely 1D or 2D. Add the required library:
require_once('class/BCGcode39.barcode.php');
Generate the colours:
// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);
After you have added all the codes, you will get this way:
Example
Since several have asked for an example here is what I was able to do to get it done
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
require_once('class/BCGcode128.barcode.php');
header('Content-Type: image/png');
$color_white = new BCGColor(255, 255, 255);
$code = new BCGcode128();
$code->parse('HELLO');
$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);
$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
If you want to actually create the image file so you can save it then change
$drawing = new BCGDrawing('', $color_white);
to
$drawing = new BCGDrawing('image.png', $color_white);
If you want to check the python version in a particular cond environment you can also use conda list python
int processed = 0;
foreach(ListViewItem lvi in listView.Items)
{
//do stuff
if (++processed == 50) break;
}
or use LINQ
foreach( ListViewItem lvi in listView.Items.Cast<ListViewItem>().Take(50))
{
//do stuff
}
or just use a regular for loop (as suggested by @sgriffinusa and @Eric J.)
for(int i = 0; i < 50 && i < listView.Items.Count; i++)
{
ListViewItem lvi = listView.Items[i];
}
Syntax change in swift 3.0
alert.addAction(UIAlertAction(title: "Okay",
style: .default,
handler: { _ in print("Foo") } ))
if you do the outer join (with the count), and then use this result as a sub-table, you can get 0 as expected (thanks to the nvl function)
Ex:
select P.person_id, nvl(A.nb_apptmts, 0) from
(SELECT person.person_id
FROM person) P
LEFT JOIN
(select person_id, count(*) as nb_apptmts
from appointment
group by person_id) A
ON P.person_id = A.person_id
You can use the perform selector for after the 0.1 sec delay method is call for that following code to do this.
[self performSelector:@selector(InsertView) withObject:nil afterDelay:0.1];
This minimal CMakeLists.txt
file compiles a simple shared library:
cmake_minimum_required(VERSION 2.8)
project (test)
set(CMAKE_BUILD_TYPE Release)
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
add_library(test SHARED src/test.cpp)
However, I have no experience copying files to a different destination with CMake. The file command with the COPY/INSTALL signature looks like it might be useful.
JavaScript is what you need. If you are loading iframe when loading the page, insert the test for iframe using the onload event. If iframe is inserted in realtime, then create a callback function on insertion and hook in whatever action you need to take :)
What about getting the version from the package meta infos:
String version = Runtime.class.getPackage().getImplementationVersion();
Prints out something like:

count_smiths = (df['LastName'] == 'Smith').sum()
If you only need to add one path per configuration (debug/release), you could set the debug command working directory:
Project | Properties | Select Configuration | Configuration Properties | Debugging | Working directory
Repeat for each project configuration.
You can do this in one query if you're willing to change its name:
ALTER TABLE table_name
DROP FOREIGN KEY `fk_name`,
ADD CONSTRAINT `fk_name2` FOREIGN KEY (`remote_id`)
REFERENCES `other_table` (`id`)
ON DELETE CASCADE;
This is useful to minimize downtime if you have a large table.
As a follow-up to the accepted answer, this is a minimal definition of the IHTMLScriptElement
interface which does not require to include additional type libraries:
[ComImport, ComVisible(true), Guid(@"3050f28b-98b5-11cf-bb82-00aa00bdce0b")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIDispatch)]
[TypeLibType(TypeLibTypeFlags.FDispatchable)]
public interface IHTMLScriptElement
{
[DispId(1006)]
string text { set; [return: MarshalAs(UnmanagedType.BStr)] get; }
}
So a full code inside a WebBrowser control derived class would look like:
protected override void OnDocumentCompleted(
WebBrowserDocumentCompletedEventArgs e)
{
base.OnDocumentCompleted(e);
// Disable text selection.
var doc = Document;
if (doc != null)
{
var heads = doc.GetElementsByTagName(@"head");
if (heads.Count > 0)
{
var scriptEl = doc.CreateElement(@"script");
if (scriptEl != null)
{
var element = (IHTMLScriptElement)scriptEl.DomElement;
element.text =
@"function disableSelection()
{
document.body.onselectstart=function(){ return false; };
document.body.ondragstart=function() { return false; };
}";
heads[0].AppendChild(scriptEl);
doc.InvokeScript(@"disableSelection");
}
}
}
}
You have to use the SelectMany
extension method or its equivalent syntax in pure LINQ.
(from model in list
where model.application == "applicationname"
from user in model.users
where user.surname == "surname"
select new { user, model }).ToList();
Option 1: Likely fastest (but not supported by some browsers if used on Document or SVGElement) :
var elements = document.getElementById('parentContainer').children;
Option 2: Likely slowest :
var elements = document.getElementById('parentContainer').getElementsByTagName('*');
Option 3: Requires change to code (wrap a form instead of a div around it) :
// Since what you're doing looks like it should be in a form...
var elements = document.forms['parentContainer'].elements;
var matches = [];
for (var i = 0; i < elements.length; i++)
if (elements[i].value.indexOf('q17_') == 0)
matches.push(elements[i]);

Constant-width stuff is first. The least important part -- the email domain -- is last and easy to filter.
a = ('A','B','C') # see it as the string "ABC"
b = ('A','B','D')
A is converted to its corresponding ASCII ord('A') #65
same for other elements
So,
>> a>b # True
you can think of it as comparing between string (It is exactly, actually)
the same thing goes for integers too.
x = (1,2,2) # see it the string "123"
y = (1,2,3)
x > y # False
because (1 is not greater than 1, move to the next, 2 is not greater than 2, move to the next 2 is less than three -lexicographically -)
The key point is mentioned in the answer above
think of it as an element is before another alphabetically not element is greater than an element and in this case consider all the tuple elements as one string.
If you use Dreamweaver you could easily note to unclosed div. In the left pane of the code view you can see there <>
highlight invalid code
button, click this button and you will notice the unclosed div highlighted and then close your unclosed div. Press F5 to refresh the page to see that any other unclosed div are there.
You can also validate your page in Dreamweaver too. File>Check Page>Browser Compatibility
, then task-pane will appear Click on Validation
, on the left side there you'll see ? button click this to validate.
Enjoy!
To sum with decimal use this:
In the javascript change parseInt with parseFloat and add this line tot.toFixed(2); for this result:
function findTotal(){
var arr = document.getElementsByName('qty');
var tot=0;
for(var i=0;i<arr.length;i++){
if(parseFloat(arr[i].value))
tot += parseFloat(arr[i].value);
}
document.getElementById('total').value = tot;
tot.toFixed(2);
}
Use step=".01" min="0" type="number" in the input filed
Qty1 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty1"/><br>
Qty2 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty2"/><br>
Qty3 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty3"/><br>
Qty4 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty4"/><br>
Qty5 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty5"/><br>
Qty6 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty6"/><br>
Qty7 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty7"/><br>
Qty8 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty8"/><br>
<br><br>
Total : <input type="number" step=".01" min="0" name="total" id="total"/>
There are several libraries available solving this problem, but the simplest is probably to use Boost Tokenizer:
#include <iostream>
#include <string>
#include <boost/tokenizer.hpp>
#include <boost/foreach.hpp>
typedef boost::tokenizer<boost::char_separator<char> > tokenizer;
std::string str("denmark;sweden;india;us");
boost::char_separator<char> sep(";");
tokenizer tokens(str, sep);
BOOST_FOREACH(std::string const& token, tokens)
{
std::cout << "<" << *tok_iter << "> " << "\n";
}
Function overloading
- functions with same name, but different number of arguments
Function overriding
- concept of inheritance. Functions with same name and same number of arguments. Here the second function is said to have overridden the first
In the case of your list items there is a little CSS you can use to achieve the desired effect.
ul.icons li {
position: relative;
padding-left: -20px; // for example
}
ul.icons li i {
position: absolute;
left: 0;
}
I have tested this in Safari on OS X.
The following code works fine:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
and generates as expected:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
On the other hand if you are writing this code inside the context of other server side construct such as an if
or foreach
you should remove the @
before the using
. For example:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
As far as your server side code is concerned, here's how to proceed:
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}
In Xcode-11.2.1
You might be see different pattern for uploading IPA
Steps:-
i) Add your apple developer id in xcode preference -> account
ii)Clean Build Folder :-
iii) Archive
iv) Tap on Distribute App
v) Choose Ad-hoc to distribute on designated device
6)Tricky part -> User can download app from company's website URL. Many of us might get stuck and start creating website url to upload ipa, which is not required. Simply write google website url with https. :)
7)Click on export and you get ipa.
8)Visit https://www.diawi.com/ & drag and drop ipa you have downloaded. & share the link to your client/user who want to test :)
You can use your own isEmpty (for multiple collection) method too. Add this your Util class.
public static boolean isEmpty(Collection... collections) {
for (Collection collection : collections) {
if (null == collection || collection.isEmpty())
return true;
}
return false;
}

I have added this function to a library I created
vanillajs-browser-helpers: https://github.com/Tokimon/vanillajs-browser-helpers/blob/master/inView.js
-------------------------------
Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.
If you don't use jQuery
then the script would be something like this:
function posY(elm) {
var test = elm, top = 0;
while(!!test && test.tagName.toLowerCase() !== "body") {
top += test.offsetTop;
test = test.offsetParent;
}
return top;
}
function viewPortHeight() {
var de = document.documentElement;
if(!!window.innerWidth)
{ return window.innerHeight; }
else if( de && !isNaN(de.clientHeight) )
{ return de.clientHeight; }
return 0;
}
function scrollY() {
if( window.pageYOffset ) { return window.pageYOffset; }
return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}
function checkvisible( elm ) {
var vpH = viewPortHeight(), // Viewport Height
st = scrollY(), // Scroll Top
y = posY(elm);
return (y > (vpH + st));
}
Using jQuery is a lot easier:
function checkVisible( elm, evalType ) {
evalType = evalType || "visible";
var vpH = $(window).height(), // Viewport Height
st = $(window).scrollTop(), // Scroll Top
y = $(elm).offset().top,
elementHeight = $(elm).height();
if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
if (evalType === "above") return ((y < (vpH + st)));
}
This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.
See in action: http://jsfiddle.net/RJX5N/2/
I hope this answers your question.
-- IMPROVED VERSION--
This is a lot shorter and should do it as well:
function checkVisible(elm) {
var rect = elm.getBoundingClientRect();
var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}
with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/
And a version with threshold
and mode
included:
function checkVisible(elm, threshold, mode) {
threshold = threshold || 0;
mode = mode || 'visible';
var rect = elm.getBoundingClientRect();
var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
var above = rect.bottom - threshold < 0;
var below = rect.top - viewHeight + threshold >= 0;
return mode === 'above' ? above : (mode === 'below' ? below : !above && !below);
}
and with a fiddle to prove it: http://jsfiddle.net/t2L274ty/2/
Using ViewPager2
and FragmentStateAdapter
:
Updating data dynamically is supported by ViewPager2
.
There is an important note in the docs on how to get this working:
Note: The DiffUtil utility class relies on identifying items by ID. If you are using ViewPager2 to page through a mutable collection, you must also override getItemId() and containsItem(). (emphasis mine)
Based on ViewPager2
documentation and Android's Github sample project there are a few steps we need to take:
Set up FragmentStateAdapter
and override the following methods: getItemCount
, createFragment
, getItemId
, and containsItem
(note: FragmentStatePagerAdapter
is not supported by ViewPager2
)
Attach adapter to ViewPager2
Dispatch list updates to ViewPager2
with DiffUtil
(don't need to use DiffUtil
, as seen in sample project)
Example:
private val items: List<Int>
get() = viewModel.items
private val viewPager: ViewPager2 = binding.viewPager
private val adapter = object : FragmentStateAdapter(this@Fragment) {
override fun getItemCount() = items.size
override fun createFragment(position: Int): Fragment = MyFragment()
override fun getItemId(position: Int): Long = items[position].id
override fun containsItem(itemId: Long): Boolean = items.any { it.id == itemId }
}
viewPager.adapter = adapter
private fun onDataChanged() {
DiffUtil
.calculateDiff(object : DiffUtil.Callback() {
override fun getOldListSize(): Int = viewPager.adapter.itemCount
override fun getNewListSize(): Int = viewModel.items.size
override fun areItemsTheSame(oldItemPosition: Int, newItemPosition: Int) =
viewPager.adapter?.getItemId(oldItemPosition) == viewModel.items[newItemPosition].id
override fun areContentsTheSame(oldItemPosition: Int, newItemPosition: Int) =
areItemsTheSame(oldItemPosition, newItemPosition)
}, false)
.dispatchUpdatesTo(viewPager.adapter!!)
}
wget is capable of doing what you are asking. Just try the following:
wget -p -k http://www.example.com/
The -p
will get you all the required elements to view the site correctly (css, images, etc).
The -k
will change all links (to include those for CSS & images) to allow you to view the page offline as it appeared online.
From the Wget docs:
‘-k’
‘--convert-links’
After the download is complete, convert the links in the document to make them
suitable for local viewing. This affects not only the visible hyperlinks, but
any part of the document that links to external content, such as embedded images,
links to style sheets, hyperlinks to non-html content, etc.
Each link will be changed in one of the two ways:
The links to files that have been downloaded by Wget will be changed to refer
to the file they point to as a relative link.
Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
downloaded, then the link in doc.html will be modified to point to
‘../bar/img.gif’. This kind of transformation works reliably for arbitrary
combinations of directories.
The links to files that have not been downloaded by Wget will be changed to
include host name and absolute path of the location they point to.
Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
../bar/img.gif), then the link in doc.html will be modified to point to
http://hostname/bar/img.gif.
Because of this, local browsing works reliably: if a linked file was downloaded,
the link will refer to its local name; if it was not downloaded, the link will
refer to its full Internet address rather than presenting a broken link. The fact
that the former links are converted to relative links ensures that you can move
the downloaded hierarchy to another directory.
Note that only at the end of the download can Wget know which links have been
downloaded. Because of that, the work done by ‘-k’ will be performed at the end
of all the downloads.
Your constructor may (later, in an extension of your software) be called from the constructor of a subclass that overrides the virtual method. Now not the subclass's implementation of the function, but the implementation of the base class will be called. So it doesn't really make sense to call a virtual function here.
However, if your design satisfies the Liskov Substitution principle, no harm will be done. Probably that's why it's tolerated - a warning, not an error.
For Swift 4.2 and above
let supportEmail = "[email protected]"
if let emailURL = URL(string: "mailto:\(supportEmail)"), UIApplication.shared.canOpenURL(emailURL)
{
UIApplication.shared.open(emailURL, options: [:], completionHandler: nil)
}
Give the user to choose many mail options(like iCloud, google, yahoo, Outlook.com - if no mail is pre-configured in his phone) to send email.
PEP 8 advises the first form for readability. You can find it here.
Function names should be lowercase, with words separated by underscores as necessary to improve readability.
The answer marked as correct has a little mistake,
String myTime = String.format("%02d:%02d:%02d",
TimeUnit.MILLISECONDS.toHours(millis),
TimeUnit.MILLISECONDS.toMinutes(millis) -
TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)), // The change is in this line
TimeUnit.MILLISECONDS.toSeconds(millis) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
for example this is an example of the value that i get:
417474:44:19
This is the solution to get the right format is:
String myTime = String.format("%02d:%02d:%02d",
//Hours
TimeUnit.MILLISECONDS.toHours(millis) -
TimeUnit.DAYS.toHours(TimeUnit.MILLISECONDS.toDays(millis)),
//Minutes
TimeUnit.MILLISECONDS.toMinutes(millis) -
TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
//Seconds
TimeUnit.MILLISECONDS.toSeconds(millis) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
getting as a result a correct format:
18:44:19
other option to get the format hh:mm:ss
is just :
Date myDate = new Date(timeinMillis);
SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss");
String myTime = formatter.format(myDate);
I had a typical Mac related issue that I could not resolve with the other suggested answers.
Mac's default file system setting is that it is case insensitive.
In my case, a colleague obviously forgot to create a uppercase letter for a branch i.e.
testBranch/ID-1 vs. testbranch/ID-2
for the Mac file system (yeah, it can be configured differently) these two branches are the same and in this case, you only get one of the two folders. And for the remaining folder you get an error.
In my case, removing the sub-folder in question in .git/logs/ref/remotes/origin resolved the problem, as the branch in question has already been merged back.
Once can also use dplyr::near
:
library(dplyr)
near(a, as.integer(a))
It applies to any vector a
, and has an optional tolerance parameter.
This answer is by no means exhaustive but it may explain it enough to make things click.
In virtual memory systems, there is a disconnect between logical and physical addresses.
An application can be given a virtual address space of (let's say) 4G. This is its usable memory and it's free to use it as it sees fit. It's a nice contiguous block of memory (from the point of view of the application).
However, it is not the only application running, and the OS has to mediate between them all. Underneath that nice contiguous model, there is a lot of mapping going on to convert logical to physical addresses.
With this mapping, the OS and hardware (I'll just call these the lower layers from here on in) is free to put the application pages anywhere it wants (either in physical memory or swapped out to secondary storage).
When the application tries to access memory at logical address 50, the lower levels can translate that to a physical address using translation tables. And, if it tries to access logical memory that's been swapped out to disk, a page fault is raised and the lower levels can bring the relevant data back into memory, at whatever physical address it wants.
In the bad old days when physical addresses were all you had, code had to be relocatable (or fixed up on load) since it could load anywhere. With virtual memory, that code (and data) can be at logical memory location 50 in a dozen different processes at the same time - it's actual physical address will be different however.
It can even be shared so that one physical copy exists in the address space of many processes at once. This is the crux of shared code (so we don't use more physical memory than we need) and shared memory to allow easy inter-process communication).
It is, of course, less efficient than a pure physical-address environment but the CPU manufacturers try to make it as insanely efficient as possible, since it's used heavily. The advantages far outweigh the disadvantages.
Please careful with $.inArray if you want to use it. I just found out that the $.inArray is only works with "Array", not with String. That's why this function will not working in IE8!
The jQuery API make confusion
The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0
--> They shouldn't say it "Similar". Since indexOf support "String" also!
'lines' term from your snippet consists of set of strings.
lines = f.readlines()
match = re.findall('[A-Z]+', lines)
You cannot send entire lines into the re.findall('pattern',<string>)
You can try to send line by line
for i in lines:
match = re.findall('[A-Z]+', i)
print match
or to convert the entire lines collection into single line (each line seperated by space)
NEW_LIST=' '.join(lines)
match=re.findall('[A-Z]+' ,NEW_LIST)
print match
This might help you
As Hrishikesh Kale has explained we need to pass the Access-Control-Expose-Headers.
Here how we can do it in the WebAPI/MVC environment:
protected void Application_BeginRequest()
{
if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
{
//These headers are handling the "pre-flight" OPTIONS call sent by the browser
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "*");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Credentials", "true");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "http://localhost:4200");
HttpContext.Current.Response.AddHeader("Access-Control-Expose-Headers", "TestHeaderToExpose");
HttpContext.Current.Response.End();
}
}
Another way is we can add code as below in the webApiconfig.cs file.
config.EnableCors(new EnableCorsAttribute("", headers: "", methods: "*",exposedHeaders: "TestHeaderToExpose") { SupportsCredentials = true });
**We can add custom headers in the web.config file as below. *
<httpProtocol>
<customHeaders>
<add name="Access-Control-Expose-Headers" value="TestHeaderToExpose" />
</customHeaders>
</httpProtocol>
we can create an attribute and decore the method with the attribute.
Happy Coding !!
To plot multiple graphs on the same figure you will have to do:
from numpy import *
import math
import matplotlib.pyplot as plt
t = linspace(0, 2*math.pi, 400)
a = sin(t)
b = cos(t)
c = a + b
plt.plot(t, a, 'r') # plotting t, a separately
plt.plot(t, b, 'b') # plotting t, b separately
plt.plot(t, c, 'g') # plotting t, c separately
plt.show()
This approach works well if you need to get all the attributes with name and value in objects returned in an array.
Example output:
[
{
name: 'message',
value: 'test2'
}
...
]
function getElementAttrs(el) {_x000D_
return [].slice.call(el.attributes).map((attr) => {_x000D_
return {_x000D_
name: attr.name,_x000D_
value: attr.value_x000D_
}_x000D_
});_x000D_
}_x000D_
_x000D_
var allAttrs = getElementAttrs(document.querySelector('span'));_x000D_
console.log(allAttrs);
_x000D_
<span name="test" message="test2"></span>
_x000D_
If you want only an array of attribute names for that element, you can just map the results:
var onlyAttrNames = allAttrs.map(attr => attr.name);
console.log(onlyAttrNames); // ["name", "message"]
There are 2 possibilities.
You really don't have Label
property.
You need to call appropriate GetProperty overload and pass the correct binding flags, e.g. BindingFlags.Public | BindingFlags.Instance
If your property is not public, you will need to use BindingFlags.NonPublic
or some other combination of flags which fits your use case. Read the referenced API docs to find the details.
EDIT:
ooops, just noticed you call GetProperty
on typeof(MyClass)
. typeof(MyClass)
is Type
which for sure has no Label
property.
This error can also occur if you are not following the marco rules
Like
#define 1K 1024 // Macro rules must be identifiers error occurs
Reason: Macro Should begin with a letter, not a number
Change to

This is the command to use to tell Gradle to upgrade the wrapper such that it will grab the distribution versions of libraries that includes source code:
./gradlew wrapper --gradle-version <version> --distribution-type all
Specifying the distribution-type with "all" will make sure Gradle downloads source files for use by your development environment.
Pros:
Cons:
Please comment or provide another answer if you know of any command line option to tell Gradle not to download sources on a build server.
Try out the CImg library. The tutorial will help you get familiarized. Once you have a CImg object, the data() function will give you access to the 2D pixel buffer array.
Here is a php script that downloads the images and creates an html file with links on the images. Credit 350D for php version, this is just elaborated..I would suggest putting this is a cron job and firing however often you need. Verified working as of May 2019.

css cannot be directly applied for the alignment of the anchor tag. The css (text-align:center;) should be applied to the parent div/element for the alignment effect to take place on the anchor tag.
Try something like:
SELECT TOP 1 compensation FROM (
SELECT TOP 2 compensation FROM employees
ORDER BY compensation DESC
) AS em ORDER BY compensation ASC
Essentially:
If the salaries aren't distinct, you can use SELECT DISTINCT TOP ...
instead.

I have the same issue, when I close the chrome window popup browser inspector its working fine for me.
I just removed all files from my bucket by using PowerShell:
Get-S3Object -BucketName YOUR_BUCKET | % { Remove-S3Object -BucketName YOUR_BUCKET -Key $_.Key -Force:$true }
As c69 mentioned there is no way to do it with pure CSS.
but you can use HTML instead:
use
<head>
<base target="_blank">
</head>
in your HTML <head>
tag for making all of page links which not include target
attribute to be opened in a new blank window by default.
otherwise you can set target attribute for each link like this:
<a href="/yourlink.html" target="_blank">test-link</a>
and it will override
<head>
<base target="_blank">
</head>
tag if it was defined previously.
Initially starting with a pyspark dataframes - I got type conversion errors (when converting to pandas df's and then appending to csv) given the schema/column types in my pyspark dataframes
Solved the problem by forcing all columns in each df to be of type string and then appending this to csv as follows:
with open('testAppend.csv', 'a') as f:
df2.toPandas().astype(str).to_csv(f, header=False)
just change SHIFT
to ORB
,
I think it make occur because of non-relevant version,
ORB is efficient and better alternative of SHIFT or SURF.
As I also face same problem when i was used cv2.SHIFT()
ERROR: AttributeError: 'module' object has no attribute 'SIFT'
Now its completely working for me please try this:
ORB = cv2.ORB()
public static boolean isParsable(String input) {
try {
Integer.parseInt(input);
return true;
} catch (final NumberFormatException e) {
return false;
}
}
I created a class wrapped in an ES6 module that solves exactly this.
It's 103 lines, no dependencies, and fairly nicely structured and documented, meant to be easy to modify/reuse.
Handles all 8 possible orientations, and is Promise-based.

Fixed by adding Google Play Services to my Module:app gradle build file. Documentation also says to update version when you update GMS.

The shortest answer is first run the fastboot command (in my ubuntu case i.e. ./fastboot-linux oem unlock) (here i'm using ubuntu 12.04 and rooting nexus4) then power on your device in fastboot mode (in nexus 4 by pressing vol-down-key and power button)
I've historically rolled my own access at a low level (XML generation and parsing) to deal with the occasional need to do SOAP style requests from Objective-C. That said, there's a library available called SOAPClient (soapclient) that is open source (BSD licensed) and available on Google Code (mac-soapclient) that might be of interest.
I won't attest to it's abilities or effectiveness, as I've never used it or had to work with it's API's, but it is available and might provide a quick solution for you depending on your needs.
Apple had, at one time, a very broken utility called WS-MakeStubs. I don't think it's available on the iPhone, but you might also be interested in an open-source library intended to replace that - code generate out Objective-C for interacting with a SOAP client. Again, I haven't used it - but I've marked it down in my notes: wsdl2objc
In CSS3:
input[type=radio] {content:url(mycheckbox.png)}
input[type=radio]:checked {content:url(mycheckbox-checked.png)}
In reality:
<span class=fakecheckbox><input type=radio><img src="checkbox.png" alt=""></span>
@media screen {.fakecheckbox img {display:none}}
@media print {.fakecheckbox input {display:none;}}
and you'll need Javascript to keep <img>
and radios in sync (and ideally insert them there in a first place).
I've used <img>
, because browsers are usually configured not to print background-image
. It's better to use image than another control, because image is non-interactive and less likely to cause problems.
Another thing to do is to load the page with a script such as:
<div id="content" onmouseover='myFunction();$(this).prop( 'onmouseover', null );'>
<script type="text/javascript">
function myFunction() {
//do something
}
myFunction();
</script>
</div>
This will load the page, then run the script and remove the event handler when the function has been run. This will not run immediately after an ajax load, but if you are waiting for the user to enter the div element, this will work just fine.
PS. Requires Jquery
[<-

I had a weird issue when an incorrect entry in MANIFEST.MF was causing loading failure. This was when I was trying to launch a very simply scala program:
Incorrect:
Main-Class: jarek.ResourceCache
Class-Path: D:/lang/scala/lib/scala-library.jar
Correct:
Main-Class: jarek.ResourceCache
Class-Path: file:///D:/lang/scala/lib/scala-library.jar
With an incorrect version, I was getting a cryptic message, the same the OP did. Probably it should say something like malformed url exception while parsing manifest file.
Using an absolute path in the manifest file is what IntelliJ uses to provide a long classpath for a program.
<body onLoad="self.focus();document.formname.name.focus()" >
formname is <form action="xxx.php" method="POST" name="formname" >
and name is <input type="text" tabindex="1" name="name" />
it works for me, checked using IE and mozilla.
autofocus, somehow didn't work for me.
My friend, you need to create those corresponding branches locally first, in order to check-out to those other two branches, using this line of code
git branch test-branch
and
git branch change-the-title
then only you will be able to do git checkout to those branches
Also after creating each branch, take latest changes of those particular branches by using git pull origin branch_name as shown in below code
git branch test-branch
git checkout test-branch
git pull origin test-branch
and for other branch named change-the-title run following code =>
git branch change-the-title
git checkout change-the-title
git pull origin change-the-title
Happy programming :)
Here is a kind of snippet for you:
app.factory('Session', function($http) {
var Session = {
data: {},
saveSession: function() { /* save session data to db */ },
updateSession: function() {
/* load data from db */
$http.get('session.json').then(function(r) { return Session.data = r.data;});
}
};
Session.updateSession();
return Session;
});

Just figured it out in Oracle Java the environmental variable is called: JAVA_TOOL_OPTIONS

A simple lodash solution that warranties 14 alpha, 3 numeric and 3 special characters, not repeated:
const generateStrongPassword = (alpha = 14, numbers = 3, special = 3) => {
const alphaChars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
const numberChars = '0123456789';
const specialChars = '!"£$%^&*()-=+_?';
const pickedChars = _.sampleSize(alphaChars, alpha)
.concat(_.sampleSize(numberChars, numbers))
.concat(_.sampleSize(specialChars, special));
return _.shuffle(pickedChars).join('');
}
const myPassword = generateStrongPassword();
While zolley's answer is perfectly right for the question, here's a more general solution for any range, plus explanation:
=COUNTIF($A$1:$C$50, INDIRECT(ADDRESS(ROW(), COLUMN(), 4))) > 1
Please note that in this example I will be using the range A1:C50
.
The first parameter ($A$1:$C$50
) should be replaced with the range on which you would like to highlight duplicates!
to highlight duplicates:
Format
> Conditional formatting...
Apply to range
, select the range to which the rule should be applied.Format cells if
, select Custom formula is
on the dropdown.Why does it work?
COUNTIF(range, criterion)
, will compare every cell in range
to the criterion
, which is processed similarly to formulas. If no special operators are provided, it will compare every cell in the range with the given cell, and return the number of cells found to be matching the rule (in this case, the comparison). We are using a fixed range (with $
signs) so that we always view the full range.
The second block, INDIRECT(ADDRESS(ROW(), COLUMN(), 4))
, will return current cell's content. If this was placed inside the cell, docs will have cried about circular dependency, but in this case, the formula is evaluated as if it was in the cell, without changing it.
ROW()
and COLUMN()
will return the row number and column number of the given cell respectively. If no parameter is provided, the current cell will be returned (this is 1-based, for example, B3
will return 3 for ROW()
, and 2 for COLUMN()
).
Then we use: ADDRESS(row, column, [absolute_relative_mode])
to translate the numeric row and column to a cell reference (like B3
. Remember, while we are inside the cell's context, we don't know it's address OR content, and we need the content in order to compare with). The third parameter takes care for the formatting, and 4
returns the formatting INDIRECT()
likes.
INDIRECT()
, will take a cell reference and return its content. In this case, the current cell's content. Then back to the start, COUNTIF()
will test every cell in the range against ours, and return the count.
The last step is making our formula return a boolean, by making it a logical expression: COUNTIF(...) > 1
. The > 1
is used because we know there's at least one cell identical to ours. That's our cell, which is in the range, and thus will be compared to itself. So to indicate a duplicate, we need to find 2 or more cells matching ours.

One can avoid the AttributeError
brought about by set_axis_labels()
method by using the matplotlib.pyplot.xlabel
and matplotlib.pyplot.ylabel
.
matplotlib.pyplot.xlabel
sets the x-axis label while the matplotlib.pyplot.ylabel
sets the y-axis label of the current axis.
Solution code:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
fig = sns.barplot(x = 'val', y = 'cat', data = fake, color = 'black')
plt.xlabel("Colors")
plt.ylabel("Values")
plt.title("Colors vs Values") # You can comment this line out if you don't need title
plt.show(fig)
Output figure:
You can use
#pragma GCC push_options
#pragma GCC optimize ("O0")
your code
#pragma GCC pop_options
to disable optimizations since GCC 4.4.
See the GCC documentation if you need more details.

You're resetting the margin on all elements in the second css block. Default margin is 40px - this should solve the problem:
.my_container ul {list-style:disc outside none; margin-left:40px;}
sudo gem install -n /usr/local/bin cocoapods
Try this. It will definately work.
Look at SELECT INTO. This will create a new table for you, which can be temporary if you want by prefixing the table name with a pound sign (#).
For example, you can do:
SELECT *
INTO #YourTempTable
FROM YourReportQuery
Here is it with a loop for all files with some extension:
ll -ltr *.filename_extension > list.lst
for i in $(cat list.lst | awk '{ print $8 }') # validate if it is the 8 column on ls
do
echo $i
sed -i '/^#/d' $i
done

When you cast a DateTime to an int it "truncates" at noon, you might want to strip the day out like so
cast(DATEADD(DAY, DATEDIFF(DAY, 0, created_date), 0) as int) as DayBucket
The newline character is actually '\n'
.
In my experience, the best way to handle this when the primary authoritative source of information for two tables which are related has to be in two separate databases is to sync a copy of the table from the primary location to the secondary location (using T-SQL or SSIS with appropriate error checking - you cannot truncate and repopulate a table while it has a foreign key reference, so there are a few ways to skin the cat on the table updating).
Then add a traditional FK relationship in the second location to the table which is effectively a read-only copy.
You can use a trigger or scheduled job in the primary location to keep the copy updated.
From 6.11. Boolean operations:
In the context of Boolean operations, and also when expressions are used by control flow statements, the following values are interpreted as false: False, None, numeric zero of all types, and empty strings and containers (including strings, tuples, lists, dictionaries, sets and frozensets). All other values are interpreted as true.
The key phrasing here that I think you are misunderstanding is "interpreted as false" or "interpreted as true". This does not mean that any of those values are identical to True or False, or even equal to True or False.
The expression '/bla/bla/bla'
will be treated as true where a Boolean expression is expected (like in an if
statement), but the expressions '/bla/bla/bla' is True
and '/bla/bla/bla' == True
will evaluate to False for the reasons in Ignacio's answer.
You can try this...
<div class="image">
<img src="" alt="" />
<h2>Text you want to display over the image</h2>
</div>
CSS
.image {
position: relative;
width: 100%; /* for IE 6 */
}
h2 {
position: absolute;
top: 200px;
left: 0;
width: 100%;
}
.pyc
contain the compiled bytecode of Python source files. The Python interpreter loads .pyc
files before .py
files, so if they're present, it can save some time by not having to re-compile the Python source code. You can get rid of them if you want, but they don't cause problems, they're not big, and they may save some time when running programs.
You can also let angular material solve the size itself depending on the content. This means you don't have to cloud your TS files with sizes that depend on your UI. You can keep these in the HTML/CSS.
my-dialog.html
<div class="myContent">
<h1 mat-dialog-title fxLayoutAlign="center">Your title</h1>
<form [formGroup]="myForm" fxLayout="column">
<div mat-dialog-content>

</form>
</div>

.myContent {
width: 300px;
height: 150px;
}
my-component.ts
const myInfo = {};
this.dialog.open(MyDialogComponent, { data: myInfo });
I have tried this pure component:
const RawHTML = ({children, className = ""}) =>
<div className={className}
dangerouslySetInnerHTML={{ __html: children.replace(/\n/g, '<br />')}} />
Features
className
prop (easier to style it)\n
to <br />
(you often want to do that)<RawHTML>{myHTML}</RawHTML>
I have placed the component in a Gist at Github: RawHTML: ReactJS pure component to render HTML
I was able to bypass all the framework messages by making the property a string in my view model.
[Range(0, 15, ErrorMessage = "Can only be between 0 .. 15")]
[StringLength(2, ErrorMessage = "Max 2 digits")]
[Remote("PredictionOK", "Predict", ErrorMessage = "Prediction can only be a number in range 0 .. 15")]
public string HomeTeamPrediction { get; set; }
Then I need to do some conversion in my get method:
viewModel.HomeTeamPrediction = databaseModel.HomeTeamPrediction.ToString();
and post method:
databaseModel.HomeTeamPrediction = int.Parse(viewModel.HomeTeamPrediction);
This works best when using the range attribute, otherwise some additional validation would be needed to make sure the value is a number.
You can also specify the type of number by changing the numbers in the range to the correct type:
[Range(0, 10000000F, ErrorMessageResourceType = typeof(GauErrorMessages), ErrorMessageResourceName = nameof(GauErrorMessages.MoneyRange))]
This is working fine for me :
public class MethodInvokerClass {
public static void main(String[] args) throws NoSuchMethodException, SecurityException, IllegalAccessException, IllegalArgumentException, ClassNotFoundException, InvocationTargetException, InstantiationException {
Class c = Class.forName(MethodInvokerClass.class.getName());
Object o = c.newInstance();
Class[] paramTypes = new Class[1];
paramTypes[0]=String.class;
String methodName = "countWord";
Method m = c.getDeclaredMethod(methodName, paramTypes);
m.invoke(o, "testparam");
}
public void countWord(String input){
System.out.println("My input "+input);
}
}
Output:
My input testparam
I am able to invoke the method by passing its name to another method (like main).
I had this problem and I didn't have my url ready untill the callback would return some data. The solution was to open blank window before starting the callback and then just set the location when the callback returns.
$scope.testCode = function () {
var newWin = $window.open('', '_blank');
service.testCode().then(function (data) {
$scope.testing = true;
newWin.location = '/Tests/' + data.url.replace(/["]/g, "");
});
};
I'm always write in the first style.
Even if a compiler is smart enough to optimize it for arrays, but still it smart if we are using DOMNodeList here or some complicated object with calculated length?
I know what the question is about arrays, but i think it is a good practice to write all your loops in one style.
In ASP.NET there is similar object, you can use Caching Portions in WebFormsUserControls in order to cache objects of a page for a period of time and save server resources. This is also known as fragment caching.
If you include this code to top of your user control, a version of the control stored in the output cache for 150 seconds.
You can create your own control that would contain expire header for a specific resource you want.
<%@ OutputCache Duration="150" VaryByParam="None" %>
This article explain it completely: Caching Portions of an ASP.NET Page
body{
height:100%
}
#app div{
height:100%
}
this works for me..
I found this question serval years ago.
recently I tried to "rewrite" the submit method. below is my code
window.onload= function (){
for(var i= 0;i<document.forms.length;i++){
(function (p){
var form= document.forms[i];
var originFn= form.submit;
form.submit=function (){
//do something you like
alert("submitting "+form.id+" using submit method !");
originFn();
}
form.onsubmit= function (){
alert("submitting "+form.id+" with onsubmit event !");
}
})(i);
}
}
<form method="get" action="" id="form1">
<input type="submit" value="??form1" />
<input type="button" name="" id="" value="button????1" onclick="document.forms[0].submit();" /></form>
It did in IE,but failed in other browsers for the same reason as "cletus"
$(function(){
$('form').sumbit{
$('this').serialize();
}
});
In jQuery, the above code would give you the URL string with POST parameters in the URL. It's not impossible to extract the POST parameters.
To use jQuery, you need to include the jQuery library. Use the following for that:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js" type="text/javascript"></script>
Looks like you are doing this from scratch. Try using available reverse engineering tools like Netbeans Entities from Database to at least get the basics automated (like embedded ids). This can become a huge headache if you have many tables. I suggest avoid reinventing the wheel and use as many tools available as possible to reduce coding to the minimum and most important part, what you intent to do.
There's PDFLayoutTextStripper that was designed to keep the format of the data.
From the README:
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import org.apache.pdfbox.pdfparser.PDFParser;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.util.PDFTextStripper;
public class Test {
public static void main(String[] args) {
String string = null;
try {
PDFParser pdfParser = new PDFParser(new FileInputStream("sample.pdf"));
pdfParser.parse();
PDDocument pdDocument = new PDDocument(pdfParser.getDocument());
PDFTextStripper pdfTextStripper = new PDFLayoutTextStripper();
string = pdfTextStripper.getText(pdDocument);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
};
System.out.println(string);
}
}
Here's the most basic version:
function collectionHas(a, b) { //helper function (see below)
for(var i = 0, len = a.length; i < len; i ++) {
if(a[i] == b) return true;
}
return false;
}
function findParentBySelector(elm, selector) {
var all = document.querySelectorAll(selector);
var cur = elm.parentNode;
while(cur && !collectionHas(all, cur)) { //keep going up until you find a match
cur = cur.parentNode; //go up
}
return cur; //will return null if not found
}
var yourElm = document.getElementById("yourElm"); //div in your original code
var selector = ".yes";
var parent = findParentBySelector(yourElm, selector);
I'm building a React server-side renderer and found this can also occur when building a separate server config from scratch. If you're seeing this error, try the following:
Example:
const serverConfig = {
name: 'server',
context: path.join(__dirname, 'src'),
entry: {serverEntry: ['./server-entry.js']},
output: {
path: path.join(__dirname, 'public'),
filename: 'server.js',
publicPath: 'public/',
libraryTarget: 'commonjs2'
},
module: {
rules: [/*...*/]
},
resolveLoader: {
modules: [
path.join(__dirname, 'node_modules')
]
},
resolve: {
modules: [
path.join(__dirname, 'node_modules')
]
}
};
used a reference like "///<reference path="web.ts" />
and then in the VS2013 project properties for building "app.ts","Typescript Build"->"Combine javascript output into file:"(checked)->"app.js"
Only one thing needs to be done to solve the problem: upgrade TeamCity to version 8.1.x or higher because support for Visual Studio 2012/2013 and MSBuild Tools 2013 was only introduced in TeamCity 8.1. Once you've upgraded your TeamCity modify MSBuild Tools Version setting in your build step accordingly ans the problem will disappear. For more info read here: http://blog.turlov.com/2014/07/upgrade-teamcity-to-enable-support-for.html
Check this out http://www.techumber.com/2015/04/html-to-pdf-conversion-using-javascript.html
Basically you need to use html2canvas and jspdf to make it work. First you will convert your dom to image and then you will use jspdf to create pdf with the images.
EDIT: A short note on how it work. We will use two libraries to make this job done. http://html2canvas.hertzen.com/ and https://github.com/MrRio/jsPDF First we will create a dom image by using html2canvas them we will use jspdf addImage method to add that image to pdf. It seems simple but there are few bugs in jsPdf and html2cavas so you may need to change dom style temporarily. Hope this helps.
Most of the time you want to get the IDs of the products in the cart so that you can make some comparison with some other logic - example settings in the backend.
In such a case you can extend the answer from @Rohil_PHPBeginner and return the IDs in an array as follows :
<?php
function njengah_get_ids_of_products_in_cart(){
global $woocommerce;
$productsInCart = array();
$items = $woocommerce->cart->get_cart();
foreach($items as $item => $values) {
$_product = wc_get_product( $values['data']->get_id());
/* Display Cart Items Content */
echo "<b>".$_product->get_title().'</b> <br> Quantity: '.$values['quantity'].'<br>';
$price = get_post_meta($values['product_id'] , '_price', true);
echo " Price: ".$price."<br>";
/**Get IDs and in put them in an Array**/
$productsInCart_Ids[] = $_product->get_id();
}
/** To Display **/
print_r($productsInCart_Ids);
/**To Return for Comparision with some Other Logic**/
return $productsInCart_Ids;
}
You cannot get the exact code, but you can get a decompiled version of it.
The most popular (and best) tool is Reflector, but there are also other .Net decompilers (such as Dis#).
You can also decompile the IL using ILDASM, which comes bundled with the .Net Framework SDK Tools.
I had this issue when I was using TouchID if that helps anyone else, wrap your success logic which likely does something with the UI in the main queue.
Note: The title of this question used to be something like "How to printf in python?"
Since people may come here looking for it based on the title, Python also supports printf-style substitution:
>>> strings = [ "one", "two", "three" ]
>>>
>>> for i in xrange(3):
... print "Item %d: %s" % (i, strings[i])
...
Item 0: one
Item 1: two
Item 2: three
And, you can handily multiply string values:
>>> print "." * 10
..........
In my experience I use const when I want to set something I may want to change later without having to hunt through the code looking for bits that have been hard coded e.g. A file path or server name.
The error in your testing is another thing though, you are tring to make another variable called x, this would be a more accurate test.
const x = 'const';
x = 'not-const';
You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015
> 01/02/2016
because 09
> 01
. You need to either put your date in a comparable string format or compare DateTime
objects which are comparable.
<?php
$date_now = date("Y-m-d"); // this format is string comparable
if ($date_now > '2016-01-02') {
echo 'greater than';
}else{
echo 'Less than';
}
Or
<?php
$date_now = new DateTime();
$date2 = new DateTime("01/02/2016");
if ($date_now > $date2) {
echo 'greater than';
}else{
echo 'Less than';
}
captain_a is right that your app needs to be public with a developer email address. But if you are still getting the error then make sure that your website is using an SSL certificate.

I had a ton of issues getting a very simple .NET Core 2.0 application to build in VS 2017. This is the error from AppVeyor, however it was essentially the same thing locally (some paths omitted for security) :
Performing first-run Webpack build...
module.js:327 throw err;
EXEC : error : Cannot find module '......../node_modules/webpack/bin/webpack.js'
at Function.Module._resolveFilename (module.js:325:15)

csproj(25,5): error MSB3073: The command "node node_modules/webpack/bin/webpack.js --config webpack.config.vendor.js" exited with code 1.
Build FAILED.
I stumbled upon this question and answer, and I noticed my local instance also had the same warning sign over the {Project Root} -> Dependencies -> npm
folder. Right clicking and hitting "Restore packages" got everything loaded up properly, and I was able to build successfully.
We can concat same column or also other column of the table.
I had a very similar requirement (importing a base64 encoded image from an external xml import file. After using xml2json-light library to convert to a json object, I was able to leverage insight from cuixiping's answer above to convert the incoming b64 encoded image to a file object.
const imgName = incomingImage['FileName'];
const imgExt = imgName.split('.').pop();
let mimeType = 'image/png';
if (imgExt.toLowerCase() !== 'png') {
mimeType = 'image/jpeg';
}
const imgB64 = incomingImage['_@ttribute'];
const bstr = atob(imgB64);
let n = bstr.length;
const u8arr = new Uint8Array(n);
while (n--) {
u8arr[n] = bstr.charCodeAt(n);
}
const file = new File([u8arr], imgName, {type: mimeType});
My incoming json object had two properties after conversion by xml2json-light: FileName and _@ttribute (which was b64 image data contained in the body of the incoming element.) I needed to generate the mime-type based on the incoming FileName extension. Once I had all the pieces extracted/referenced from the json object, it was a simple task (using cuixiping's supplied code reference) to generate the new File object which was completely compatible with my existing classes that expected a file object generated from the browser element.
Hope this helps connects the dots for others.
The solution is:
pylab.savefig('foo.png')
Use itertools.islice
, starting at index 17. It will automatically skip the 17 first lines.
import itertools
with open('file.txt') as f:
for line in itertools.islice(f, 17, None): # start=17, stop=None
# process lines
From : http://download.oracle.com/javase/6/docs/api/java/sql/Timestamp.html#compareTo(java.sql.Timestamp)
public int compareTo(Timestamp ts)
Compares this Timestamp object to the given Timestamp object. Parameters: ts - the Timestamp object to be compared to this Timestamp object Returns: the value 0 if the two Timestamp objects are equal; a value less than 0 if this Timestamp object is before the given argument; and a value greater than 0 if this Timestamp object is after the given argument. Since: 1.4
You need to use a SimpleDateFormat
(dd-MM-yyyy
will be the format) to parse the 2 input strings to Date
objects and then use the Date#before(otherDate)
(or) Date#after(otherDate)
to compare them.
Try to implement the code yourself.
Update: For a better approach, please refer to Blackus's answer in the same thread.
If you are not averse to using JavaScript and Regex, you can use the below solution to find all width
and height
properties in the style
attribute and replace
them with nothing.
//Get the value of style attribute based on element's Id
var originalStyle = document.getElementById('sample_id').getAttribute('style');
var regex = new RegExp(/(width:|height:).+?(;[\s]?|$)/g);
//Replace matches with null
var modStyle = originalStyle.replace(regex, "");
//Set the modified style value to element using it's Id
document.getElementById('sample_id').setAttribute('style', modStyle);

router.post('/login', async(req, res) => {
return res.send({redirect: '/yoururl'});
})

i have same problem what i did i just downloaded 32-bit dll and added it to my bin folder this is solved my problem
I get the error in another situation, and here are the problem and the solution:
I have 2 classes derived from a same base class named LevledItem:
public partial class Team : LeveledItem
{
//Everything is ok here!
}
public partial class Story : LeveledItem
{
//Everything is ok here!
}
But in their DbContext, I copied some code but forget to change one of the class name:
public class MFCTeamDbContext : DbContext
{
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
//Other codes here
modelBuilder.Entity<LeveledItem>()
.Map<Team>(m => m.Requires("Type").HasValue(ItemType.Team));
}
public class ProductBacklogDbContext : DbContext
{
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
//Other codes here
modelBuilder.Entity<LeveledItem>()
.Map<Team>(m => m.Requires("Type").HasValue(ItemType.Story));
}
Yes, the second Map< Team> should be Map< Story>. And it cost me half a day to figure it out!
On your solution explorer window, right click to References, select Add Reference, go to .NET tab, find and add Microsoft.CSharp.
Alternatively add the Microsoft.CSharp NuGet package.
Install-Package Microsoft.CSharp
according to http://www.maketecheasier.com/combine-multiple-pdf-files-with-pdftk/ the command should be

note that you should download windows version of pdftk
There is no full-proof method to prevent your images being downloaded/stolen.
But, some solutions like: watermarking your images(from client side or server side), implement a background image, disable/prevent right clicks, slice images into small pieces and then present as a complete image to browser, you can also use flash to show images.
Personally, recommended methods are: Watermarking and flash. But it is a difficult and almost impossible mission to accomplish. As long as user is able to "see" that image, means they take "screenshot" to steal the image.
There was conflict in java version. Resolved after using 1.8 for maven.

Extra info:
If you are using PhpStorm as IDE, after updating the path variable you need to restart PhpStorm so that it takes effect.
Restarting terminal window was not enough for me. (PhpStorm 2020.3.2)
Should you want to resort to using a plug-in, malihu-custom-scrollbar-plugin, could do the job. It performs an actual scroll, not just a jump. You can even specify the speed/momentum of scroll. It also lets you set up a menu (list of links to scroll to), which have their CSS changed based on whether the anchors-to-scroll-to are in viewport, and other useful features.
There are demo on the author's site and let our company site serve as a real-world example too.
FYI. You can now just update VS 2012:

Before trying to update tensorflow try updating pip
pip install --upgrade pip
If you are upgrading from a previous installation of TensorFlow < 0.7.1, you should uninstall the previous TensorFlow and protobuf using,
pip uninstall tensorflow
to make sure you get a clean installation of the updated protobuf dependency.
Uninstall the TensorFlow on your system, and check out Download and Setup to reinstall again.
If you are using pip install, go check the available version over https://storage.googleapis.com/tensorflow, search keywords with linux/cpu/tensorflow to see the availabilities.
Then, set the path for download and execute in sudo.
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.0.0-py2-none-any.whl
$ sudo pip install --upgrade $TF_BINARY_URL

You can use the Java UUID class to store these values, instead of byte arrays:
UUID
public UUID(long mostSigBits,
long leastSigBits)
Constructs a new UUID using the specified data. mostSigBits is used for the most significant 64 bits of the UUID and leastSigBits becomes the least significant 64 bits of the UUID.
Here is updated version from Darrelk answer. It is implemented using C# extension methods. It does not allocate memory (new Random()) every time this method is called.
public static class RandomExtensionMethods
{
public static double NextDoubleRange(this System.Random random, double minNumber, double maxNumber)
{
return random.NextDouble() * (maxNumber - minNumber) + minNumber;
}
}
Usage (make sure to import the namespace that contain the RandomExtensionMethods class):
var random = new System.Random();
double rx = random.NextDoubleRange(0.0, 1.0);
double ry = random.NextDoubleRange(0.0f, 1.0f);
double vx = random.NextDoubleRange(-0.005f, 0.005f);
double vy = random.NextDoubleRange(-0.005f, 0.005f);
@rap-2-h and @Ztuons Ch's answer doesn't allow for the showTooltips
option to be active, but what you can do is create and layer a second canvas
object behind the one rendering the chart.
The important part is the styling required in the divs and for the canvas object itself so that they render on top of each other.

Here's the jsfiddle: https://jsfiddle.net/68vxqyak/1/
Thanks to Service Workers, it is possible to implement a solution similar to Adam's purely on the client-side, granted the browser supports it. Just circumvent heartbeat requests:
// The delay should be longer than the heartbeat by a significant enough amount that there won't be false positives
const liveTimeoutDelay = 10000
let liveTimeout = null
global.self.addEventListener('fetch', event => {
clearTimeout(liveTimeout)
liveTimeout = setTimeout(() => {
console.log('User left page')
// handle page leave
}, liveTimeoutDelay)
// Forward any events except for hearbeat events
if (event.request.url.endsWith('/heartbeat')) {
event.respondWith(
new global.Response('Still here')
)
}
})
As long as your Fragment creates a View, you can use the IBinder (window token) from that view after it has been attached. For example, you can override onActivityCreated in your Fragment:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
}
git add .
equals git add -A .
adds files to index only from current and children folders.
git add -A
adds files to index from all folders in working tree.
P.S.: information relates to Git 2.0 (2014-05-28).
Generally you can achieve the same effect by using normal blocking IO and multiplexing several IO operations using select(2)
, poll(2)
or some other system calls available on your system.
See The C10K problem for the comparison of approaches to scalable IO multiplexing.
Follow the below steps
From feature/branch (enter the below command)
git checkout master
git pull
git checkout feature/branchname
git merge master
Regular Expressions (abbreviated "regex" or "reg-ex") is a string that defines a search pattern.
What replaceFirst()
does is it uses the regular expression provided in the parameters and replaces the first result from the search with whatever you pass in as the other parameter.
What you want to do is convert the string to an array using the String
class' charAt()
method, and then use Character.toUpperCase()
to change the character to upper case (obviously). Your code would look like this:
char first = Character.toUpperCase(userIdea.charAt(0));
betterIdea = first + userIdea.substring(1);
Or, if you feel comfortable with more complex, one-lined java code:
betterIdea = Character.toUpperCase(userIdea.charAt(0)) + userIdea.substring(1);
Both of these do the same thing, which is converting the first character of userIdea
to an upper case character.
I solved it by commenting out:
in httpd.conf
according to: http://www.apachelounge.com/viewtopic.php?t=4461
This simple(st) solution doesn't provide indentation, but it is nevertheless much easier on the human eye. Also it allows the xml to be handled more easily by simple tools like grep, head, awk, etc.
Use sed
to replace '<' with itself preceeded with a newline.
And as mentioned by Gilles, it's probably not a good idea to use this in production.
# check you are getting more than one line out
sed 's/</\n</g' sample.xml | wc -l
# check the output looks generally ok
sed 's/</\n</g' sample.xml | head
# capture the pretty xml in a different file
sed 's/</\n</g' sample.xml > prettySample.xml
The following regular expression in Python works well for detecting URL(s) in the text:
source_text = '''
text1
text2
http://url.com/bla1/blah1/
text3
text4
http://url.com/bla2/blah2/
text5
text6 '''
import re
url_reg = r'[a-z]*[:.]+\S+'
result = re.sub(url_reg, '', source_text)
print(result)
Output:
text1
text2
text3
text4
text5
text6
If you try a lot of these answers out on different resolutions, computers with multiple monitors, etc. you may find that they don't work reliably. This is because you need to use a transform to get the mouse position relative to the current screen, not the entire viewing area which consists of all your monitors. Something like this...(where "this" is a WPF window).
var transform = PresentationSource.FromVisual(this).CompositionTarget.TransformFromDevice;
var mouse = transform.Transform(GetMousePosition());
public System.Windows.Point GetMousePosition()
{
var point = Forms.Control.MousePosition;
return new Point(point.X, point.Y);
}
You could use the CSS calc
parameter to calculate the height dynamically like so:
.dynamic-height {_x000D_
color: #000;_x000D_
font-size: 12px;_x000D_
margin-top: calc(100% - 10px);_x000D_
text-align: left;_x000D_
}
_x000D_
<div class='dynamic-height'>_x000D_
<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem.</p>_x000D_

Have you looked into ZXING? I've been using it successfully to create barcodes. You can see a full working example in the bitcoin application src
// this is a small sample use of the QRCodeEncoder class from zxing
try {
// generate a 150x150 QR code
Bitmap bm = encodeAsBitmap(barcode_content, BarcodeFormat.QR_CODE, 150, 150);
if(bm != null) {
image_view.setImageBitmap(bm);
}
} catch (WriterException e) { //eek }
In HTML:
<input type="submit" id="btnSubmit" name="btnSubmit" value="Save Changes" />
<input type="submit" id="btnDelete" name="btnDelete" value="Delete" />
In PHP:
if (isset($_POST["btnSubmit"])){
// "Save Changes" clicked
} else if (isset($_POST["btnDelete"])){
// "Delete" clicked
}
I'm sure it is a late response, but maybe is useful for somebody else.
You can put all your <li>
element content into <a>
tag and add the following css:
li a {
display: block;
/* and you can use padding for additional space if needs, as a clickable area / or other styling */
padding: 5px 20px;
}
There is a general way of converting recursive traversal to iterator by using a lazy iterator which concatenates multiple iterator suppliers (lambda expression which returns an iterator). See my Converting Recursive Traversal to Iterator.
This is standards compliant and cross-browser safe.
Example: http://jsfiddle.net/kv9pw/
var span = document.getElementById('someID');
while( span.firstChild ) {
span.removeChild( span.firstChild );
}
span.appendChild( document.createTextNode("some new content") );
The accepted answer throws a ProtocolException at:
OutputStream os = conn.getOutputStream();
because it does not enable the output for the URLConnection object. The solution should include this:
conn.setDoOutput(true);
to make it work.
I found deinit
works good for me:
git submodule deinit <submodule-name>
git rm <submodule-name>
From git docs:
deinit
Unregister the given submodules, i.e. remove the whole
submodule.$name
section from .git/config together with their work tree.
I'd suggest getting into one of the JS libraries out there. They ensure compatibility so you can get up and running really fast. jQuery and DOJO are both really great. To do what you're trying to do in jQuery, for example, it would go something like this:
<script type="text/javascript" language="JavaScript">
$.ajax({
url: "x.html",
context: document.body,
success: function(response) {
$("#yourDiv").html(response);
}
});
</script>
You can decode it to str with receive.decode('utf_8')
.
XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
Where str
is your XML string. See the MSDN article for more info.
While the marked answer gets it working, all you really need to add to the webconfig is:
<handlers>
<!-- Your other remove tags-->
<remove name="UrlRoutingModule-4.0"/>
<!-- Your other add tags-->
<add name="UrlRoutingModule-4.0" path="*" verb="*" type="System.Web.Routing.UrlRoutingModule" preCondition=""/>
</handlers>
Note that none of those have a particular order, though you want your removes before your adds.
The reason that we end up getting a 404 is because the Url Routing Module only kicks in for the root of the website in IIS. By adding the module to this application's config, we're having the module to run under this application's path (your subdirectory path), and the routing module kicks in.
It's worth to mention that CLOB / BLOB data types and their sizes are supported by MySQL 5.0+, so you can choose the proper data type for your need.
http://dev.mysql.com/doc/refman/5.7/en/storage-requirements.html
Data Type Date Type Storage Required
(CLOB) (BLOB)
TINYTEXT TINYBLOB L + 1 bytes, where L < 2**8 (255)
TEXT BLOB L + 2 bytes, where L < 2**16 (64 K)
MEDIUMTEXT MEDIUMBLOB L + 3 bytes, where L < 2**24 (16 MB)
LONGTEXT LONGBLOB L + 4 bytes, where L < 2**32 (4 GB)
where L stands for the byte length of a string
There is indeed a Groovier Way.
if(members){
//Some work
}
does everything if members
is a collection. Null check as well as empty check (Empty collections are coerced to false
). Hail Groovy Truth. :)
Just use negative margins, in the second div say:
<div style="margin-top: -25px;">
And make sure to set the z-index property to get the layering you want.
Just catch the submit event and prevent that, then do ajax
$(document).ready(function () {
$('#myform').on('submit', function(e) {
e.preventDefault();
$.ajax({
url : $(this).attr('action') || window.location.pathname,
type: "GET",
data: $(this).serialize(),
success: function (data) {
$("#form_output").html(data);
},
error: function (jXHR, textStatus, errorThrown) {
alert(errorThrown);
}
});
});
});
I tried the lookup('pipe,'date') method and got trouble when I push the playbook to the tower. The tower is somehow using UTC timezone. All play executed as early as the + hours of my TZ will give me one day later of the actual date.
For example: if my TZ is Asia/Manila I supposed to have UTC+8. If I execute the playbook earlier than 8:00am in Ansible Tower, the date will follow to what was in UTC+0. It took me a while until I found this case. It let me use the date option '-d \"+8 hours\" +%F'. Now it gives me the exact date that I wanted.
Below is the variable I set in my playbook:
vars:
cur_target_wd: "{{ lookup('pipe','date -d \"+8 hours\" +%Y/%m-%b/%d-%a') }}"
That will give me the value of "cur_target_wd = 2020/05-May/28-Thu" even I run it earlier than 8:00am now.
The answer is definitely implementation-specific. To find out definitively for your platform/compiler, just add this output somewhere in your code:
printf ("sizeof time_t is: %d\n", sizeof(time_t));
If the answer is 4 (32 bits) and your data is meant to go beyond 2038, then you have 25 years to migrate your code.
Your data will be fine if you store your data as a string, even if it's something simple like:
FILE *stream = [stream file pointer that you've opened correctly];
fprintf (stream, "%d\n", (int)time_t);
Then just read it back the same way (fread, fscanf, etc. into an int), and you have your epoch offset time. A similar workaround exists in .Net. I pass 64-bit epoch numbers between Win and Linux systems with no problem (over a communications channel). That brings up byte-ordering issues, but that's another subject.
To answer paxdiablo's query, I'd say that it printed "19100" because the program was written this way (and I admit I did this myself in the '80's):
time_t now;
struct tm local_date_time;
now = time(NULL);
// convert, then copy internal object to our object
memcpy (&local_date_time, localtime(&now), sizeof(local_date_time));
printf ("Year is: 19%02d\n", local_date_time.tm_year);
The printf
statement prints the fixed string "Year is: 19" followed by a zero-padded string with the "years since 1900" (definition of tm->tm_year
). In 2000, that value is 100, obviously. "%02d"
pads with two zeros but does not truncate if longer than two digits.
The correct way is (change to last line only):
printf ("Year is: %d\n", local_date_time.tm_year + 1900);
New question: What's the rationale for that thinking?
Add an Application Configuration File
item to your project (Right -Click Project > Add item). This will create a file called app.config
in your project.
Edit the file by adding entries like <add key="keyname" value="someValue" />
within the <appSettings>
tag.
Add a reference to the System.Configuration
dll, and reference the items in the config using code like ConfigurationManager.AppSettings["keyname"]
.
You just need to include the standard.jar
file in your project build path.
You can use the Description
attribute to get that friendly name. You can use the code below:
public static string ToStringEnums(Enum en)
{
Type type = en.GetType();
MemberInfo[] memInfo = type.GetMember(en.ToString());
if (memInfo != null && memInfo.Length > 0)
{
object[] attrs = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
if (attrs != null && attrs.Length > 0)
return ((DescriptionAttribute)attrs[0]).Description;
}
return en.ToString();
}
An example of when you would want to use this method: When your enum value is EncryptionProviderType
and you want enumVar.Tostring()
to return "Encryption Provider Type".
Prerequisite: All enum members should be applied with the attribute [Description("String to be returned by Tostring()")]
.
Example enum:
enum ExampleEnum
{
[Description("One is one")]
ValueOne = 1,
[Description("Two is two")]
ValueTow = 2
}
And in your class, you would use it like this:
ExampleEnum enumVar = ExampleEnum.ValueOne;
Console.WriteLine(ToStringEnums(enumVar));

I always get in here, for this topic. I'll put my code in here so i (or other) can use it next time. (Phew hate to search into my repository code).
Add the permission:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Add receiver and service:
<receiver android:enabled="true" android:name=".BootUpReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<service android:name="Launcher" />
Create class Launcher:
public class Launcher extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
new AsyncTask<Service, Void, Service>() {
@Override
protected Service doInBackground(Service... params) {
Service service = params[0];
PackageManager pm = service.getPackageManager();
try {
Intent target = pm.getLaunchIntentForPackage("your.package.id");
if (target != null) {
service.startActivity(target);
synchronized (this) {
wait(3000);
}
} else {
throw new ActivityNotFoundException();
}
} catch (ActivityNotFoundException | InterruptedException ignored) {
}
return service;
}
@Override
protected void onPostExecute(Service service) {
service.stopSelf();
}
}.execute(this);
return START_STICKY;
}

Intent target = new Intent(context, MainActivity.class);
target.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(target);
}
}

connection.connect((hostname, port))
end = timer()
delta = end - start
except (socket.timeout, socket.gaierror) as error:
logger.debug('telnet error: ', error)
delta = None
finally:
connection.close()
return {
hostname: delta
}
def test_telnet_is_null_when_host_unreachable(self):
hostname = 'unreachable'
response = network_utils.telnet(hostname)
self.assertDictEqual(response, {'unreachable': None})
def test_telnet_give_time_when_reachable(self):
hostname = '127.0.0.1'
response = network_utils.telnet(hostname, port=22)
self.assertGreater(response[hostname], 0)
I would try putting a
Log.e("SOMETAG", "dialog button was clicked");
before the dialog.dismiss() line in your code to see if it actually reaches that section.
