Simply create an input element and trigger the click.
var input = document.createElement('input');
input.type = 'file';
input.click();
This is the most basic, pop a select-a-file dialog, but its no use for anything without handling the selected file...
Adding an onchange event to the newly created input would allow us to do stuff once the user has selected the file.
var input = document.createElement('input');
input.type = 'file';
input.onchange = e => {
var file = e.target.files[0];
}
input.click();
At the moment we have the file variable storing various information :
file.name // the file's name including extension
file.size // the size in bytes
file.type // file type ex. 'application/pdf'
Great!
In order to get to the actual content of the file, for various reasons. place an image, load into canvas, create a window with Base64 data url, etc. we would need to use the FileReader API
We would create an instance of the FileReader, and load our user selected file reference to it.
var input = document.createElement('input');
input.type = 'file';
input.onchange = e => {
// getting a hold of the file reference
var file = e.target.files[0];
// setting up the reader
var reader = new FileReader();
reader.readAsText(file,'UTF-8');
// here we tell the reader what to do when it's done reading...
reader.onload = readerEvent => {
var content = readerEvent.target.result; // this is the content!
console.log( content );
}
}
input.click();
Trying pasting the above code into your devtool's console window, it should produce a select-a-file dialog, after selecting the file, the console should now print the contents of the file.
Let's try to create a file select dialog to change stackoverflows background image to something more spicy...
var input = document.createElement('input');
input.type = 'file';
input.onchange = e => {
// getting a hold of the file reference
var file = e.target.files[0];
// setting up the reader
var reader = new FileReader();
reader.readAsDataURL(file); // this is reading as data url
// here we tell the reader what to do when it's done reading...
reader.onload = readerEvent => {
var content = readerEvent.target.result; // this is the content!
document.querySelector('#content').style.backgroundImage = 'url('+ content +')';
}
}
input.click();
open devtools, and paste the above code into console window, this should pop a select-a-file dialog, upon selecting an image, stackoverflows content box background should change to the image selected.
Cheers!

Not quite sure why the answer above needs to go into benchmarks, string buffers, tests, etc.
Very simply, you can rename your Python script to "pythonscript.cgi". Post that in your cgi-bin directory, add the appropriate permissions and browse to it.
This is a great link you can start with.
Hope that helps.
EDIT (09/12/2015): The second link has long been removed. Replaced it with one that provides information referenced from the original.
jQuerify is the perfect extension to embed jQuery into Chrome Console and is as simple as you can imagine. This extension also indicates if jQuery has been already embedded into a page.
This extension is used to embed jQuery into any page you want. It allows to use jQuery in the console shell (You can invoke Chrome console by Ctrl + Shift + j".).
To embed jQuery into the selected tab click on extension button.
You could register to the KeyDown-Event of the Textbox, look if the pressed key is Enter and then execute the EventHandler of the button:
private void buttonTest_Click(object sender, EventArgs e)
{
MessageBox.Show("Hello World");
}
private void textBoxTest_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
buttonTest_Click(this, new EventArgs());
}
}
did you try 'localhost/phpmyadmin' ? (notice the lowercase)
PHPMyAdmin tends to have inconsistent directory names across its versions/distributions.
Edit: Confirm the URL by checking the name of the root folder!
If the config was the primary issue (and it may still be nthary) you would get a php error, not a http "Object not found" error,
As for the config error, here are some steps to correct it:
Once you have confirmed which case your PHPMyAdmin is in, confirm that your config.inc.php is located in its root directory.
If it is, rename it to something else as a backup. Then copy the config.sample.inc.php (in the same directory) and rename it to config.inc.php
Check if it works.
If its does, then open up both the new config.inc.php (that works) and the backup you took earlier of your old one. Compare them and copy/replace the important parts that you want to carry over, the file (in its default state) isn't that long and it should be relatively easy to do so.
N.B. If the reason that you want your old config is because of security setup that you once had, I would definitely suggest still using the security wizard built into XAMPP so that you can be assured that you have the right configuration for the right version. There is no guarantee that different XAMPP/PHPMyAdmin versions implement security/anything in the same way.

</main>Whew. That was a lot for a "sample" but I feel it really drives home the effect and point: we can certainly select a label for a checked input control without it being a sibling. The secret lies in keeping the input tags a child to only what they need to be (in this case - only the body element).
Since the label element doesn't actually utilize the :checked pseudo selector, it doesn't matter that the labels are stored in the header. It does have the added benefit that since the header is a sibling element we can use the ~ generic sibling selector to move from the input[type=radio]:checked DOM element to the header container and then use descendant/child selectors to access the labels themselves, allowing the ability to style them when their respective radio boxes/checkboxes are selected.
Not only can we style the labels, but also style other content that may be descendants of a sibling container relative to all of the inputs. And now for the moment you've all been waiting for, the JSFIDDLE! Go there, play with it, make it work for you, find out why it works, break it, do what you do!
Hopefully that all makes sense and fully answers the question and possibly any follow ups that may crop up.
I think you should install API 18 from android sdk if not already installed, otherwise you can try "invalidate caches and restart" (Find: File->invalidate caches and restart).

@oldFoo varchar(7)
set @foo = '138'
set @oldFoo = '0' + @foo
You could do what React warns you when you try to set the "selected" property of the <option>:

Over the years I've been honing a perfect set of headers for this that work brilliantly in all browsers that I know of
// these headers avoid IE problems when using https:
// see http://support.microsoft.com/kb/812935
header("Cache-Control: must-revalidate");
header("Pragma: must-revalidate");
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=$filename.csv");
Simply add style="line-height:0" to each cell. This works in IE because it sets the line-height of both existant and non-existant text to about 19px and that forces the cells to expand vertically in most versions of IE. Regardless of whether or not you have text this needs to be done for IE to correctly display rows less than 20px high.
If you want to do this via the designer you can do it by following the instructions here "Save changes is not permitted" when changing an existing column to be nullable
Subprocess module is a good module to launch subprocesses. You can use it to call shell commands as this:
subprocess.call(["ls","-l"]);
#basic syntax
#subprocess.call(args, *)
You can see its documentation here.
If you have your script written in some .sh file or a long string, then you can use os.system module. It is fairly simple and easy to call:
import os
os.system("your command here")
# or
os.system('sh file.sh')
This command will run the script once, to completion, and block until it exits.

I believe that a memory mapped file will be the fastest solution. I tried four functions: the function posted by the OP (opcount); a simple iteration over the lines in the file (simplecount); readline with a memory-mapped filed (mmap) (mapcount); and the buffer read solution offered by Mykola Kharechko (bufcount).
I ran each function five times, and calculated the average run-time for a 1.2 million-line text file.
Windows XP, Python 2.5, 2GB RAM, 2 GHz AMD processor
Here are my results:
mapcount : 0.465599966049
simplecount : 0.756399965286
bufcount : 0.546800041199
opcount : 0.718600034714
Edit: numbers for Python 2.6:
mapcount : 0.471799945831
simplecount : 0.634400033951
bufcount : 0.468800067902
opcount : 0.602999973297
So the buffer read strategy seems to be the fastest for Windows/Python 2.6
Here is the code:
from __future__ import with_statement
import time
import mmap
import random
from collections import defaultdict
def mapcount(filename):
f = open(filename, "r+")
buf = mmap.mmap(f.fileno(), 0)
lines = 0
readline = buf.readline
while readline():
lines += 1
return lines
def simplecount(filename):
lines = 0
for line in open(filename):
lines += 1
return lines
def bufcount(filename):
f = open(filename)
lines = 0
buf_size = 1024 * 1024
read_f = f.read # loop optimization
buf = read_f(buf_size)
while buf:
lines += buf.count('\n')
buf = read_f(buf_size)
return lines
def opcount(fname):
with open(fname) as f:
for i, l in enumerate(f):
pass
return i + 1
counts = defaultdict(list)
for i in range(5):
for func in [mapcount, simplecount, bufcount, opcount]:
start_time = time.time()
assert func("big_file.txt") == 1209138
counts[func].append(time.time() - start_time)
for key, vals in counts.items():
print key.__name__, ":", sum(vals) / float(len(vals))
In order to remove the by default security for jenkins in Windows OS,

If you need to make single element you can use this construction:
$('<option/>', {
'class': this.dataID,
'text': this.s_dataValue
}).appendTo('.subCategory');
But if you need to print many elements you can use this construction:
function printOptions(arr){
jQuery.each(arr, function(){
$('<option/>', {
'value': this.dataID,
'text': this.s_dataValue
}).appendTo('.subCategory');
});
}
You just need to wrap object in ()
var arr = [{_x000D_
id: 1,_x000D_
name: 'bill'_x000D_
}, {_x000D_
id: 2,_x000D_
name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)The date filter always formats the dates using the local timezone. You'll have to write your own filter, based on the getUTCXxx() methods of Date, or on a library like moment.js.

FileStorage contains stream field. This object must extend IO or file object, so it must contain read and other similar methods. FileStorage also extend stream field object attributes, so you can just use file.read() instead file.stream.read(). Also you can use save argument with dst parameter as StringIO or other IO or file object to copy FileStorage.stream to another IO or file object.

What is the difference between them?
Image: the generic Linux kernel binary image file.
zImage: a compressed version of the Linux kernel image that is self-extracting.
uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.
Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:
Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.
(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)
Which type of kernel image do I have to use?
You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.
ADDENDUM
I know that u-boot needs a kernel in uImage format.
That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.
Either lock or interlocked increment is what you are looking for.
Volatile is definitely not what you're after - it simply tells the compiler to treat the variable as always changing even if the current code path allows the compiler to optimize a read from memory otherwise.
e.g.
while (m_Var)
{ }
if m_Var is set to false in another thread but it's not declared as volatile, the compiler is free to make it an infinite loop (but doesn't mean it always will) by making it check against a CPU register (e.g. EAX because that was what m_Var was fetched into from the very beginning) instead of issuing another read to the memory location of m_Var (this may be cached - we don't know and don't care and that's the point of cache coherency of x86/x64). All the posts earlier by others who mentioned instruction reordering simply show they don't understand x86/x64 architectures. Volatile does not issue read/write barriers as implied by the earlier posts saying 'it prevents reordering'. In fact, thanks again to MESI protocol, we are guaranteed the result we read is always the same across CPUs regardless of whether the actual results have been retired to physical memory or simply reside in the local CPU's cache. I won't go too far into the details of this but rest assured that if this goes wrong, Intel/AMD would likely issue a processor recall! This also means that we do not have to care about out of order execution etc. Results are always guaranteed to retire in order - otherwise we are stuffed!
With Interlocked Increment, the processor needs to go out, fetch the value from the address given, then increment and write it back -- all that while having exclusive ownership of the entire cache line (lock xadd) to make sure no other processors can modify its value.
With volatile, you'll still end up with just 1 instruction (assuming the JIT is efficient as it should) - inc dword ptr [m_Var]. However, the processor (cpuA) doesn't ask for exclusive ownership of the cache line while doing all it did with the interlocked version. As you can imagine, this means other processors could write an updated value back to m_Var after it's been read by cpuA. So instead of now having incremented the value twice, you end up with just once.
Hope this clears up the issue.

p.s. What prompted this very late reply? All the replies were so blatantly incorrect (especially the one marked as answer) in their explanation I just had to clear it up for anyone else reading this. shrugs
p.p.s. I'm assuming that the target is x86/x64 and not IA64 (it has a different memory model). Note that Microsoft's ECMA specs is screwed up in that it specifies the weakest memory model instead of the strongest one (it's always better to specify against the strongest memory model so it is consistent across platforms - otherwise code that would run 24-7 on x86/x64 may not run at all on IA64 although Intel has implemented similarly strong memory model for IA64) - Microsoft admitted this themselves - http://blogs.msdn.com/b/cbrumme/archive/2003/05/17/51445.aspx.

This example works best for React.
I guess it depends on what you want. For simple objects, I guess you could use the second methods. When your objects grow larger and you're planning on using similar objects, I guess the first method would be better. That way you can also extend it using prototypes.
Example:
function Circle(radius) {
this.radius = radius;
}
Circle.prototype.getCircumference = function() {
return Math.PI * 2 * this.radius;
};
Circle.prototype.getArea = function() {
return Math.PI * this.radius * this.radius;
}
I am not a big fan of the third method, but it's really useful for dynamically editing properties, for example var foo='bar'; var bar = someObject[foo];.

For future reference (since this is google's top answer ATM), to prevent jQuery UI from overriding bootstrap's or your custom style, you need to create a custom download and select the no-theme theme. That will only include jQuery UI's resets, and not overload bootstrap's style for various elements.
While we're at it, some jQuery UI components (such as datepicker) have a native bootstrap implementation. The native bootstrap implementations will use the bootstrap css classes, attributes and layouts, so should have a better integration with the rest of the framework.
If you will try to load such a large file through phpmyadmin then you would need to change upload_file_size in php.ini to your requirements and then after uploading you will have to revert it back. What will happen? If you would like to load a 3GB file. You will have to change those parameters in php.ini again.
The best solution to solve this issue to open command prompt in windows.
Find path of wamp mysql directory.
Usually, it is C:/wamp64/bin/mysql/mysqlversion/bin/mysql.exe
Execute mysql -u root
You will be in mysql command prompt
Switch database with use command.
mysql> use database_name
mysql> source [file_path]
In case of Windows, here is the example.
mysql> source C:/sqls/sql1GB.sql
That's it. If you will have a database over 10GB or 1000GB. This method will still work for you.
Perhaps it has no special meaning and only needs to be rendered in italics to separate it presentationally from the text preceding it.
If it has no special meaning, why does it need to be separated presentationally from the text preceding it? This run of text looks a bit weird, because I’ve italicised it for no reason.
I do take your point though. It’s not uncommon for designers to produce designs that vary visually, without varying meaningfully. I’ve seen this most often with boxes: designers will give us designs including boxes with various combinations of colours, corners, gradients and drop-shadows, with no relation between the styles, and the meaning of the content.
Because these are reasonably complex styles (with associated Internet Explorer issues) re-used in different places, we create classes like box-1, box-2, so that we can re-use the styles.
The specific example of making some text italic is too trivial to worry about though. Best leave minutiae like that for the Semantic Nutters to argue about.
Adding on, you can turn off the creation of vshost files for your Release build configuration and have it enabled for Debug.

Excerpt from MSDN How to: Disable the Hosting Process
Calls to certain APIs can be affected when the hosting process is enabled. In these cases, it is necessary to disable the hosting process to return the correct results.
To disable the hosting process
When the hosting process is disabled, several debugging features are unavailable or experience decreased performance. For more information, see Debugging and the Hosting Process.
In general, when the hosting process is disabled:
- The time needed to begin debugging .NET Framework applications increases.
- Design-time expression evaluation is unavailable.
- Partial trust debugging is unavailable.
How do I change Android Studio editor's background color?
Changing Editor's Background
Open Preference > Editor (In IDE Settings Section) > Colors & Fonts > Darcula or Any item available there
IDE will display a dialog like this, Press 'No'
Darcula color scheme has been set for editors. Would you like to set Darcula as default Look and Feel?
Changing IDE's Theme
Open Preference > Appearance (In IDE Settings Section) > Theme > Darcula or Any item available there
Press OK. Android Studio will ask you to restart the IDE.
Almost certainly more efficient than using Strings:
int firstDigit(int x) {
while (x > 9) {
x /= 10;
}
return x;
}
(Works only for nonnegative integers.)
Extending the above post by Tom, if you need a class type declaration and access the singleton instance using a variable, the code below might be of help. I like this notation as the code is little self guiding.
function SingletonClass(){
if ( arguments.callee.instance )
return arguments.callee.instance;
arguments.callee.instance = this;
}
SingletonClass.getInstance = function() {
var singletonClass = new SingletonClass();
return singletonClass;
};
To access the singleton, you would
var singleTon = SingletonClass.getInstance();
Have you tried:
BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable();
Bitmap bitmap = drawable.getBitmap();
Try this:
String output = response.getEntity(String.class);
EDIT
Thanks to @Martin Spamer to mention that it will work for Jersey 1.x jars only. For Jersey 2.x use
String output = response.readEntity(String.class);
make sure you add {} around Html.RenderPartial, as:
@{Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});}
not
@Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});
Make sure that you're putting your query string at the end of your URL when doing a GET request.
$qry_str = "?x=10&y=20"; $ch = curl_init(); // Set query data here with the URL curl_setopt($ch, CURLOPT_URL, 'http://example.com/test.php' . $qry_str); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3); $content = trim(curl_exec($ch)); curl_close($ch); print $content;
With a POST you pass the data via the CURLOPT_POSTFIELDS option instead of passing it in the CURLOPT__URL. ------------------------------------------------------------------------- $qry_str = "x=10&y=20"; curl_setopt($ch, CURLOPT_URL, 'http://example.com/test.php'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3); // Set request method to POST curl_setopt($ch, CURLOPT_POST, 1); // Set query data here with CURLOPT_POSTFIELDS curl_setopt($ch, CURLOPT_POSTFIELDS, $qry_str); $content = trim(curl_exec($ch)); curl_close($ch); print $content;
Note from the curl_setopt() docs for CURLOPT_HTTPGET (emphasis added):
[Set CURLOPT_HTTPGET equal to]
TRUEto reset the HTTP request method to GET.
Since GET is the default, this is only necessary if the request method has been changed.
You can use Query.values, Query.values
session.query(SomeModel).values('id', 'user')
Try this

cmd = "ping -c {} -W {} {}".format(count, wait_sec, server).split(' ')
try:
output = subprocess.check_output(cmd).decode().strip()
lines = output.split("\n")
total = lines[-2].split(',')[3].split()[1]
loss = lines[-2].split(',')[2].split()[0]
timing = lines[-1].split()[3].split('/')
return {
'type': 'rtt',
'min': timing[0],
'avg': timing[1],
'max': timing[2],
'mdev': timing[3],

Here are functions you can use for creating and retrieving cookies.
function createCookie(name, value, days) {
var expires;
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
}
else {
expires = "";
}
document.cookie = name + "=" + value + expires + "; path=/";
}
function getCookie(c_name) {
if (document.cookie.length > 0) {
c_start = document.cookie.indexOf(c_name + "=");
if (c_start != -1) {
c_start = c_start + c_name.length + 1;
c_end = document.cookie.indexOf(";", c_start);
if (c_end == -1) {
c_end = document.cookie.length;
}
return unescape(document.cookie.substring(c_start, c_end));
}
}
return "";
}
Generally mysql uses this date format 'Y-m-d H:i:s'
In case you need C++11 compatibility and cannot use boost, here is a boost-compatible drop-in with an example of usage:
#include <iostream>
#include <string>
static bool starts_with(const std::string str, const std::string prefix)
{
return ((prefix.size() <= str.size()) && std::equal(prefix.begin(), prefix.end(), str.begin()));
}
int main(int argc, char* argv[])
{
bool usage = false;
unsigned int foos = 0; // default number of foos if no parameter was supplied
if (argc > 1)
{
const std::string fParamPrefix = "-f="; // shorthand for foo
const std::string fooParamPrefix = "--foo=";
for (unsigned int i = 1; i < argc; ++i)
{
const std::string arg = argv[i];
try
{
if ((arg == "-h") || (arg == "--help"))
{
usage = true;
} else if (starts_with(arg, fParamPrefix)) {
foos = std::stoul(arg.substr(fParamPrefix.size()));
} else if (starts_with(arg, fooParamPrefix)) {
foos = std::stoul(arg.substr(fooParamPrefix.size()));
}
} catch (std::exception& e) {
std::cerr << "Invalid parameter: " << argv[i] << std::endl << std::endl;
usage = true;
}
}
}
if (usage)
{
std::cerr << "Usage: " << argv[0] << " [OPTION]..." << std::endl;
std::cerr << "Example program for parameter parsing." << std::endl << std::endl;
std::cerr << " -f, --foo=N use N foos (optional)" << std::endl;
return 1;
}
std::cerr << "number of foos given: " << foos << std::endl;
}
Try mkdir -p:
mkdir -p foo
Note that this will also create any intermediate directories that don't exist; for instance,
mkdir -p foo/bar/baz
will create directories foo, foo/bar, and foo/bar/baz if they don't exist.
Some implementation like GNU mkdir include mkdir --parents as a more readable alias, but this is not specified in POSIX/Single Unix Specification and not available on many common platforms like macOS, various BSDs, and various commercial Unixes, so it should be avoided.
If you want an error when parent directories don't exist, and want to create the directory if it doesn't exist, then you can test for the existence of the directory first:
[ -d foo ] || mkdir foo
You should create custom helper for just changing string format except using controller call.
HTML:
<video
id="video-active"
class="video-active"
width="640"
height="390"
controls="controls">
<source src="myvideo.mp4" type="video/mp4">
</video>
<div id="current">0:00</div>
<div id="duration">0:00</div>
JavaScript:
$(document).ready(function(){
$("#video-active").on(
"timeupdate",
function(event){
onTrackedVideoFrame(this.currentTime, this.duration);
});
});
function onTrackedVideoFrame(currentTime, duration){
$("#current").text(currentTime); //Change #current to currentTime
$("#duration").text(duration)
}
Notes:
Every 15 to 250ms, or whenever the MediaController's media controller position changes, whichever happens least often, the user agent must queue a task to fire a simple event named timeupdate at the MediaController.

For anything with requests to URLs you might want to check out requests. For JSON in particular:
>>> import requests
>>> r = requests.get('https://github.com/timeline.json')
>>> r.json()
[{u'repository': {u'open_issues': 0, u'url': 'https://github.com/...
I don't know what qualifies as best but zxing has a qr code generator for java, is actively developed, and is liberally licensed.
Make sure you've copied the whole public key to authorized_keys; the ssh rsa prefix is necessary for the key to work.
For the case I met, I found there are missing modules after make. So I did the following:
Do you need to parse arbitrary JSON structures, or just data that's specific to your application. If the latter, you can make it a lot lighter and more efficient by not having to generate any hash table/map structure mapping JSON keys to values; you can instead just store the data directly into struct fields or whatever.
On your command prompt type sqllocaldb start
Use <add name="defaultconnection" connectionString="Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=tododb;Integrated Security=True" providerName="System.Data.SqlClient" />
First off, a PetStore is not a farm.
Let's get past this though. You actually don't need access to the private members, you have everything you need in the public interface:
Animal_* getAnimal_(int i);
void addAnimal_(Animal_* newAnimal);
These are the methods you're given access to and these are the ones you should use.
I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ??
Simple, you call addAnimal. It's public and it also increments sizeF.
Also, note that
PetStore()
{
idF=0;
};
is equivalent to
PetStore() : Farm()
{
idF=0;
};
i.e. the base constructor is called, base members are initialized.
Use IIF.
<asp:Label ID="Label18" Text='<%# IIF(Eval("item") Is DBNull.Value,"0", Eval("item") %>'
runat="server"></asp:Label>
You can use BindingAdapter like this:
@BindingAdapter("bringToFront")
public static void bringToFront(View view, Boolean flag) {
if (flag) {
view.bringToFront();
}
}
<ImageView
...
app:bringToFront="@{true}"/>
For now i think best emulator is https://app.crossbrowsertesting.com
It has real sizes and virtual keyboard (that is the most important thing) , zooming events...
Also https://appetize.io/demo has same things but it has time limit.
First, you should list your plugins:
cordova plugin list
With this result, you can simply do:
cordova plugin remove <PLUGIN_NAME>
For example:
cordova plugin remove org.apache.cordova.media
Hope it helps.
My problem turned out to be, I had altered a table to add a column called Char.
As this is a reserved word in MS Access it needed square brakcets (Single or double quote are no good) in order for the alter statement to work before I could then update the newly created column.
Here an example with Swift 3.0
let manager = AFHTTPSessionManager(sessionConfiguration: URLSessionConfiguration.default)
manager.requestSerializer = AFJSONRequestSerializer()
manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Content-Type")
manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Accept")
if authenticated {
if let user = UserDAO.currentUser() {
manager.requestSerializer.setValue("Authorization", forHTTPHeaderField: user.headerForAuthentication())
}
}
manager.post(url, parameters: parameters, progress: nil, success: { (task: URLSessionDataTask, responseObject: Any?) in
if var jsonResponse = responseObject as? [String: AnyObject] {
// here read response
}
}) { (task: URLSessionDataTask?, error: Error) in
print("POST fails with error \(error)")
}
Looks like recentish versions of Git (I'm on git v2.20) allow one to simply say
git fetch --prune --prune-tags
Much cleaner!
https://git-scm.com/docs/git-fetch#_pruning
You can also configure git to always prune tags when fetching:
git config fetch.pruneTags true
If you only want to prune tags when fetching from a specific remote, you can use the remote.<remote>.pruneTags option. For example, to always prune tags when fetching from origin but not other remotes,
git config remote.origin.pruneTags true
Note to self: "Remove UseDefaultCredentials = false".
You can either use a module like Math::Round:
use Math::Round;
my $rounded = round( $float );
Or you can do it the crude way:
my $rounded = sprintf "%.0f", $float;
FYI: Same problem with running on a build server (Jenkins with msbuild 15 installed, driven from VS 2017 on a .NET Core 2.1 web project).
In my case it was the use of the "publish" target with msbuild that ignored the profile.
So my msbuild command started with:
msbuild /t:restore;build;publish
This correctly triggerred the publish process, but no combination or variation of "/p:PublishProfile=FolderProfile" ever worked to select the profile I wanted to use ("FolderProfile").
When I stopped using the publish target:
msbuild /t:restore;build /p:DeployOnBuild=true /p:PublishProfile=FolderProfile
I (foolishly) thought that it would make no difference, but as soon as I used the DeployOnBuild switch it correctly picked up the profile.
You cannot create different "variable names" but you can create different object properties. There are many ways to do whatever it is you're actually trying to accomplish. In your case I would just do
for (var i = myArray.length - 1; i >= 0; i--) { console.log(eval(myArray[i])); }; More generally you can create object properties dynamically, which is the type of flexibility you're thinking of.
var result = {}; for (var i = myArray.length - 1; i >= 0; i--) { result[myArray[i]] = eval(myArray[i]); }; I'm being a little handwavey since I don't actually understand language theory, but in pure Javascript (including Node) references (i.e. variable names) are happening at a higher level than at runtime. More like at the call stack; you certainly can't manufacture them in your code like you produce objects or arrays. Browsers do actually let you do this anyway though it's terrible practice, via
window['myVarName'] = 'namingCollisionsAreFun'; (per comment)
It doesn't seem possible with SQL Server 2008 alone. You're going to need a third-party tool's help.
It will help you make your .bak act like a live database:
While @tymeJV gave a correct answer, the way to do this to be inline with angular would be:
ng-click="hidePrefs()"
and then in your controller:
$scope.hidePrefs = function() {
$scope.prefs = false;
}
I want to extend Olcay's nice answer. His approach is good, your login page controller should be like this to put the referrer url into session:
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage(HttpServletRequest request, Model model) {
String referrer = request.getHeader("Referer");
request.getSession().setAttribute("url_prior_login", referrer);
// some other stuff
return "login";
}
And you should extend SavedRequestAwareAuthenticationSuccessHandler and override its onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) method. Something like this:
public class MyCustomLoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
public MyCustomLoginSuccessHandler(String defaultTargetUrl) {
setDefaultTargetUrl(defaultTargetUrl);
}
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {
HttpSession session = request.getSession();
if (session != null) {
String redirectUrl = (String) session.getAttribute("url_prior_login");
if (redirectUrl != null) {
// we do not forget to clean this attribute from session
session.removeAttribute("url_prior_login");
// then we redirect
getRedirectStrategy().sendRedirect(request, response, redirectUrl);
} else {
super.onAuthenticationSuccess(request, response, authentication);
}
} else {
super.onAuthenticationSuccess(request, response, authentication);
}
}
}
Then, in your spring configuration, you should define this custom class as a bean and use it on your security configuration. If you are using annotation config, it should look like this (the class you extend from WebSecurityConfigurerAdapter):
@Bean
public AuthenticationSuccessHandler successHandler() {
return new MyCustomLoginSuccessHandler("/yourdefaultsuccessurl");
}
In configure method:
@Override
protected void configure(HttpSecurity http) throws Exception {
http
// bla bla
.formLogin()
.loginPage("/login")
.usernameParameter("username")
.passwordParameter("password")
.successHandler(successHandler())
.permitAll()
// etc etc
;
}
If you deal with .xlsm file instead of .xls you can use the old method. I was trying to modify vbaProject.bin in .xlsm several times using DBP->DBx method by it didn't work, also changing value of DBP didn't. So I was very suprised that following worked :
1. Save .xlsm as .xls.
2. Use DBP->DBx method on .xls.
3. Unfortunately some erros may occur when using modified .xls file, I had to save .xls as .xlsx and add modules, then save as .xlsm.
For anyone still looking into this in order to learn specifically what a stack is, the term "stack" is referring to a "solution stack." A solution stack is simply a complete set of software to address a given problem, usually by combining to provide the platform or infrastructure necessary. This term is the parent of both "server stack" and "web stack." Accordingly, a LAMP stack is a specific and complete set of software specifically aimed at serving dynamic content over the web.
Some extra reading:

I use this code to costum my bottom navigation item
BottomNavigationView navigation = this.findViewById(R.id.my_bottom_navigation);
Menu menu = navigation.getMenu();
menu.findItem(R.id.nav_wall_see).setTitle("Hello");
The checkbox is in a td, so need to get the parent first:
$("input:checkbox").on("change", function() {
$(this).parent().next().find("label").text("TESTTTT");
});
Alternatively, find a label which has a for with the same id (perhaps more performant than reverse traversal) :
$("input:checkbox").on("change", function() {
$("label[for='" + $(this).attr('id') + "']").text("TESTTTT");
});
Or, to be more succinct just this.id:
$("input:checkbox").on("change", function() {
$("label[for='" + this.id + "']").text("TESTTTT");
});
I've never been happy with the way anybody explains this.
The key to understanding closures is to understand what JS would be like without closures.
Without closures, this would throw an error
function outerFunc(){
var outerVar = 'an outerFunc var';
return function(){
alert(outerVar);
}
}
outerFunc()(); //returns inner function and fires it
Once outerFunc has returned in an imaginary closure-disabled version of JavaScript, the reference to outerVar would be garbage collected and gone leaving nothing there for the inner func to reference.
Closures are essentially the special rules that kick in and make it possible for those vars to exist when an inner function references an outer function's variables. With closures the vars referenced are maintained even after the outer function is done or 'closed' if that helps you remember the point.
Even with closures, the life cycle of local vars in a function with no inner funcs that reference its locals works the same as it would in a closure-less version. When the function is finished, the locals get garbage collected.
Once you have a reference in an inner func to an outer var, however it's like a doorjamb gets put in the way of garbage collection for those referenced vars.
A perhaps more accurate way to look at closures, is that the inner function basically uses the inner scope as its own scope foudnation.
But the context referenced is in fact, persistent, not like a snapshot. Repeatedly firing a returned inner function that keeps incrementing and logging an outer function's local var will keep alerting higher values.
function outerFunc(){
var incrementMe = 0;
return function(){ incrementMe++; console.log(incrementMe); }
}
var inc = outerFunc();
inc(); //logs 1
inc(); //logs 2
You can also do this as well (shorter cut) instead of having to do instance declaration. You do this in JSON instead.
class Book {
public BookId: number;
public Title: string;
public Author: string;
public Price: number;
public Description: string;
}
var bks: Book[] = [];
bks.push({BookId: 1, Title:"foo", Author:"foo", Price: 5, Description: "foo"}); //This is all done in JSON.
Pass in the straight XML instead of a dictionary.
The proper way of using NSLog, as the warning tries to explain, is the use of a formatter, instead of passing in a literal:
Instead of:
NSString *digit = [[sender titlelabel] text];
NSLog(digit);
Use:
NSString *digit = [[sender titlelabel] text];
NSLog(@"%@",digit);
It will still work doing that first way, but doing it this way will get rid of the warning.
class CallByName():
def method1(self):
pass
def method2(self):
pass
def method3(self):
pass
def get_method(self, method_name):
method = getattr(self, method_name)
return method()
callbyname = CallByName()
method1 = callbyname.get_method(method_name)
```
Yet another full outer join
As was not that happy with the simplicity and the readability of the other propositions, I ended up with this :
It does not have the pretension to be fast ( about 800 ms to join 1000 * 1000 on a 2020m CPU : 2.4ghz / 2cores). To me, it is just a compact and casual full outer join.
It works the same as a SQL FULL OUTER JOIN (duplicates conservation)

If you are using 5.5.x:
const UPDATED_AT = null;
And for 'created_at' field, you can use:
const CREATED_AT = null;
Make sure you are on the newest version. (This was broken in Laravel 5.5.0 and fixed again in 5.5.5).
I stumbled on this question while trying to do the same thing (I think). Here is how I did it:
df['index_col'] = df.index
You can then sort on the new index column, if you like.
Use the vim-way:
$ ex +'bufdo retab' -cxa **/*.*
globstar (**) for recursion, activate by shopt -s globstar.**/*.c.To modify tabstop, add +'set ts=2'.
However the down-side is that it can replace tabs inside the strings.
So for slightly better solution (by using substitution), try:
$ ex -s +'bufdo %s/^\t\+/ /ge' -cxa **/*.*
Or by using ex editor + expand utility:
$ ex -s +'bufdo!%!expand -t2' -cxa **/*.*
For trailing spaces, see: How to remove trailing whitespaces for multiple files?
You may add the following function into your .bash_profile:
# Convert tabs to spaces.
# Usage: retab *.*
# See: https://stackoverflow.com/q/11094383/55075
retab() {
ex +'set ts=2' +'bufdo retab' -cxa $*
}
I propose to use
SET time_zone = 'proper timezone';
being done once right after connect to database. and after this all timestamps will be converted automatically when selecting them.
Also check if your xampp is installed in the main directory like C or D or E and not in or within a folder of that directory? i.e. ( "D:/Xampp" or is it "D:/something/Xampp") if its not in the main path of the directory, it will show this error.
copy your xampp directory from "D:\Something\Xampp" to "D:"
So it becomes like this "D:\Xampp"
and the issue will be resolved.
I really like @Angelin's answer. But if you're dealing with some legacy code where this is not practical, this technique might work for you.

$_SESSION['curr_pos_sub'] = $_POST['last_pos_sub'];
}
}
Then at the end of the form, stick in last_pos_sub as follows:
<input type="hidden" name="last_pos_sub" value=<?php echo $_POST['last_pos_sub']; ?>>
Try this , if you are using PHP 5.3+, in php
$query_date = '2010-02-04';
$date = new DateTime($query_date);
//First day of month
$date->modify('first day of this month');
$firstday= $date->format('Y-m-d');
//Last day of month
$date->modify('last day of this month');
$lastday= $date->format('Y-m-d');
For finding next month last date, modify as follows,
$date->modify('last day of 1 month');
echo $date->format('Y-m-d');
and so on..
The accepted answer shows too complicated way. As Forresto claims in his answer, "it does seem to add them in the DOM explorer, but not on the screen" and the reason for this is different namespaces for html and svg.
The easiest workaround is to "refresh" whole svg. After appending circle (or other elements), use this:
$("body").html($("body").html());
This does the trick. The circle is on the screen.
Or if you want, use a container div:
$("#cont").html($("#cont").html());
And wrap your svg inside container div:
<div id="cont">
<svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 100" width="200px" height="100px">
</svg>
</div>
The functional example:
http://jsbin.com/ejifab/1/edit
The advantages of this technique:
$('svg').prepend('<defs><marker></marker><mask></mask></defs>'); like you do in jQuery. $("#cont").html($("#cont").html()); their attributes can be edited using jQuery. EDIT:
The above technique works with "hard coded" or DOM manipulated ( = document.createElementNS etc.) SVG only. If Raphael is used for creating elements, (according to my tests) the linking between Raphael objects and SVG DOM is broken if $("#cont").html($("#cont").html()); is used. The workaround to this is not to use $("#cont").html($("#cont").html()); at all and instead of it use dummy SVG document.
This dummy SVG is first a textual representation of SVG document and contains only elements that are needed. If we want eg. to add a filter element to Raphael document, the dummy could be something like <svg id="dummy" style="display:none"><defs><filter><!-- Filter definitons --></filter></defs></svg>. The textual representation is first converted to DOM using jQuery's $("body").append() method. And when the (filter) element is in DOM, it can be queried using standard jQuery methods and appended to the main SVG document which is created by Raphael.
Why this dummy is needed? Why not to add a filter element strictly to Raphael created document? If you try it using eg. $("svg").append("<circle ... />"), it is created as html element and nothing is on screen as described in answers. But if the whole SVG document is appended, then the browser handles automatically the namespace conversion of all the elements in SVG document.
An example enlighten the technique:
// Add Raphael SVG document to container element
var p = Raphael("cont", 200, 200);
// Add id for easy access
$(p.canvas).attr("id","p");
// Textual representation of element(s) to be added
var f = '<filter id="myfilter"><!-- filter definitions --></filter>';
// Create dummy svg with filter definition
$("body").append('<svg id="dummy" style="display:none"><defs>' + f + '</defs></svg>');
// Append filter definition to Raphael created svg
$("#p defs").append($("#dummy filter"));
// Remove dummy
$("#dummy").remove();
// Now we can create Raphael objects and add filters to them:
var r = p.rect(10,10,100,100);
$(r.node).attr("filter","url(#myfilter)");
Full working demo of this technique is here: http://jsbin.com/ilinan/1/edit.
( I have (yet) no idea, why $("#cont").html($("#cont").html()); doesn't work when using Raphael. It would be very short hack. )
You can use a library called select2
You also can look at this Stackoverflow Question & Answer
<select id="selectBox" style="width: 500px">
<option value="1" data-desc="this is my <br> multiple line 1">option 1</option>
<option value="2" data-desc="this is my <br> multiple line 2">option 2</option>
</select>
In javascript
$(function(){
$("#selectBox").select2({
templateResult: formatDesc
});
function formatDesc (opt) {
var optdesc = $(opt.element).attr('data-desc');
var $opt = $(
'<div><strong>' + opt.text + '</strong></div><div>' + optdesc + '</div>'
);
return $opt;
};
});
Try this
<script>
$().ready(function(){
$('.coupon_question').live('click',function()
{
if ($('.coupon_question').is(':checked')) {
$(".answer").show();
} else {
$(".answer").hide();
}
});
});
</script>
CodeIgniter Active Records do not currently support sub-queries, However I use the following approach:
#Create where clause
$this->db->select('id_cer');
$this->db->from('revokace');
$where_clause = $this->db->_compile_select();
$this->db->_reset_select();
#Create main query
$this->db->select('*');
$this->db->from('certs');
$this->db->where("`id` NOT IN ($where_clause)", NULL, FALSE);
_compile_select() and _reset_select() are two undocumented (AFAIK) methods which compile the query and return the sql (without running it) and reset the query.
On the main query the FALSE in the where clause tells codeigniter not to escape the query (or add backticks etc) which would mess up the query. (The NULL is simply because the where clause has an optional second parameter we are not using)
However you should be aware as _compile_select() and _reset_select() are not documented methods it is possible that there functionality (or existence) could change in future releases.
count_unique_words <-function(wlist) {
ucountlist = list()
unamelist = c()
for (i in wlist)
{
if (is.element(i, unamelist))
ucountlist[[i]] <- ucountlist[[i]] +1
else
{
listlen <- length(ucountlist)
ucountlist[[i]] <- 1
unamelist <- c(unamelist, i)
}
}
ucountlist
}
expt_counts <- count_unique_words(population)
for(i in names(expt_counts))
cat(i, expt_counts[[i]], "\n")
Hiding on the Client Side with javascript
Using plain old javascript, you can easily hide the same element in this manner:
var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";
Then to show again:
myDivElem.style.display = "";
jQuery makes hiding elements a little simpler if you prefer to use jQuery:
var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();
... and to show:
myDiv.show();
I did these to get good results out of an image which has not very small text.
And if the still not getting good results, scale the image to 150% or 200%.
You can use this as a generic solution:
import os
def getParentDir(path, level=1):
return os.path.normpath( os.path.join(path, *([".."] * level)) )

This works for me. Got solution from MYSQL webpage
In MySQL run below queries:
FLUSH PRIVILEGES;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'New_Password';
URIs came about from the need to identify resources on the Web, and other Internet resources such as electronic mailboxes in a uniform and coherent way. So, one can introduce a new type of widget: URIs to identify widget resources or use tel: URIs to have web links cause telephone calls to be made when invoked.
Some URIs provide information to locate a resource (such as a DNS host name and a path on that machine), while some are used as pure resource names. The URL is reserved for identifiers that are resource locators, including 'http' URLs such as http://stackoverflow.com, which identifies the web page at the given path on the host. Another example is 'mailto' URLs, such as mailto:[email protected], which identifies the mailbox at the given address.
URNs are URIs that are used as pure resource names rather than locators. For example, the URI: mid:[email protected] is a URN that identifies the email message containing it in its 'Message-Id' field. The URI serves to distinguish that message from any other email message. But it does not itself provide the message's address in any store.
Strictly speaking; With no Java EE features your app hardly need an appserver at all ;-)
Like others have pointed out JBoss has a (more or less) full Java EE stack while Tomcat is a webcontainer only. JBoss can be configured to only serve as a webcontainer as well, it'd then just be a thin wrapper around the included tomcat webcontainer. That way you could have an almost as lightweight JBoss, which would actually just be a thin "wrapper" around Tomcat. That would be almost as lightweigth.
If you won't need any of the extras JBoss has to offer, go for the one you're most comfortable with. Which is easiest to configure and maintain for you?
Unless one want a separate function in global namespacs, we can use lambda functions for creating threads.
One of the major advantage of creating thread using lambda is that we don't need to pass local parameters as an argument list. We can use capture list for the same and the closure property of lambda will take care of the lifecycle.
Here is a sample code
int main() {
int localVariable = 100;
thread th { [=](){
cout<<"The Value of local variable => "<<localVariable<<endl;
}};
th.join();
return 0;
}
By far, I've found C++ lambdas to be the best way of creating threads especially for simpler thread functions
Take a look at my implementation. It's safe from null lists.
IList<string> all= new List<string>();
if (letterForm.SecretaryPhone!=null)// first list may be null
all=all.Concat(letterForm.SecretaryPhone).ToList();
if (letterForm.EmployeePhone != null)// second list may be null
all= all.Concat(letterForm.EmployeePhone).ToList();
if (letterForm.DepartmentManagerName != null) // this is not list (its just string variable) so wrap it inside list then concat it
all = all.Concat(new []{letterForm.DepartmentManagerPhone}).ToList();
Be aware that in Spring it has non academic meaning.
The abstract interface is a warning to the developer not to use it for @Autowired.
I hope that spring/eclipse @Autowired will look at this attribute and warn/fail about usages of such.
A real example: @Service proxy under @Transnational to a @Repository need to use same basic methods however they should use different interfaces that extends this abstract interface due to @Autowired.
(I call this XXXSpec interface)
No.
The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.
You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).
RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.
Hence:
Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"
Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".
Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"
Means "This is a PNG image. Please save it as a file, preferably named picture.png".
Content-Type: image/png
Content-Disposition: inline; filename="picture.png"
Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".
Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).
You just use the method
public Object put(Object key, Object value)
if the key was already present in the Map then the previous value is returned.
Never use .onclick(), or similar attributes from a userscript! (It's also poor practice in a regular web page).
The reason is that userscripts operate in a sandbox ("isolated world"), and onclick operates in the target-page scope and cannot see any functions your script creates.
Always use addEventListener()Doc (or an equivalent library function, like jQuery .on()).
So instead of code like:
something.outerHTML += '<input onclick="resetEmotes()" id="btnsave" ...>'
You would use:
something.outerHTML += '<input id="btnsave" ...>'
document.getElementById ("btnsave").addEventListener ("click", resetEmotes, false);
For the loop, you can't pass data to an event listener like that See the doc. Plus every time you change innerHTML like that, you destroy the previous event listeners!
Without refactoring your code much, you can pass data with data attributes. So use code like this:
for (i = 0; i < EmoteURLLines.length; i++) {
if (checkIMG (EmoteURLLines[i])) {
localStorage.setItem ("nameEmotes", JSON.stringify (EmoteNameLines));
localStorage.setItem ("urlEmotes", JSON.stringify (EmoteURLLines));
localStorage.setItem ("usageEmotes", JSON.stringify (EmoteUsageLines));
if (i == 0) {
console.log (resetSlot ());
}
emoteTab[2].innerHTML += '<span style="cursor:pointer;" id="'
+ EmoteNameLines[i]
+ '" data-usage="' + EmoteUsageLines[i] + '">'
+ '<img src="' + EmoteURLLines[i] + '" /></span>'
;
} else {
alert ("The maximum emote (" + EmoteNameLines[i] + ") size is (36x36)");
}
}
//-- Only add events when innerHTML overwrites are done.
var targetSpans = emoteTab[2].querySelectorAll ("span[data-usage]");
for (var J in targetSpans) {
targetSpans[J].addEventListener ("click", appendEmote, false);
}
Where appendEmote is like:
function appendEmote (zEvent) {
//-- this and the parameter are special in event handlers. see the linked doc.
var emoteUsage = this.getAttribute ("data-usage");
shoutdata.value += emoteUsage;
}
.outerHTML or .innerHTML, you trash any event handlers on the affected nodes. If you use this method beware of that fact.Let's assume that you have a List<String> strings that you want the first item from.
There are several ways to do that:
Java (pre-8):
String firstElement = null;
if (!strings.isEmpty() && strings.size() > 0) {
firstElement = strings.get(0);
}
Java 8:
Optional<String> firstElement = strings.stream().findFirst();
Guava
String firstElement = Iterables.getFirst(strings, null);
Apache commons (4+)
String firstElement = (String) IteratorUtils.get(strings, 0);
Apache commons (before 4)
String firstElement = (String) CollectionUtils.get(strings, 0);
Followed by or encapsulated within the appropriate checks or try-catch blocks.
Kotlin:
In Kotlin both Arrays and most of the Collections (eg: List) have a first method call.
So your code would look something like this
for a List:
val stringsList: List<String?> = listOf("a", "b", null)
val first: String? = stringsList.first()
for an Array:
val stringArray: Array<String?> = arrayOf("a", "b", null)
val first: String? = stringArray.first()
Followed by or encapsulated within the appropriate checks or try-catch blocks.
Kotlin also includes safer ways to do that for kotlin.collections, for example firstOrNull or getOrElse, or getOrDefault when using JRE8
If I understand your question correctly, you are asking how you can create class level constants (static - in C++ parlance) such that you don't a) replicate the overhead in every instance, and b have to recompute what is otherwise constant.
The language has evolved - as every reader knows, but as I test this in Xcode 6.3.1, the solution is:
import Swift
class MyClass {
static let testStr = "test"
static let testStrLen = count(testStr)
init() {
println("There are \(MyClass.testStrLen) characters in \(MyClass.testStr)")
}
}
let a = MyClass()
// -> There are 4 characters in test
I don't know if the static is strictly necessary as the compiler surely only adds only one entry per const variable into the static section of the binary, but it does affect syntax and access. By using static, you can refer to it even when you don't have an instance: MyClass.testStrLen.
You are actually ignoring exception in your code. But I suggest you to reconsider.
Here is a quote from Coding Crimes: Ignoring Exceptions
For a start, the exception should be logged at the very least, not just written out to the console. Also, in most cases, the exception should be thrown back to the caller for them to deal with. If it doesn't need to be thrown back to the caller, then the exception should be handled. And some comments would be nice too.
The usual excuse for this type of code is "I didn't have time", but there is a ripple effect when code is left in this state. Chances are that most of this type of code will never get out in the final production. Code reviews or static analysis tools should catch this error pattern. But that's no excuse, all this does is add time to the maintainance and debugging of the software.
Even if you are ignoring it I suggest you to use specific exception names instead of superclass name. ie., Use NullPointerException instead of Exception in your catch clause.
SELECT resultAfter you run a SELECT: Query > Export Results...
In the Navigator, right click on the table > Table Data Export Wizard
All columns and rows are included by default, so click on Next.
Select File Path, type, Field Separator (by default it is ;, not ,!!!) and click on Next.
Click Next > Next > Finish and the file is created in the specified location
I solved that problem.
I was implementing an OSI Layer (slider window, Level 2) for a network simulation in C++ (Eclipse Juno). I had frames (template <class T>) and its states (state pattern, forward declaration).
The solution is as follows:
In the *.cpp file, you must include the Header file that you forward, i.e.
ifndef STATE_H_
#define STATE_H_
#include <stdlib.h>
#include "Frame.h"
template <class T>
class LinkFrame;
using namespace std;
template <class T>
class State {
protected:
LinkFrame<int> *myFrame;
}
Its cpp:
#include "State.h"
#include "Frame.h"
#include "LinkFrame.h"
template <class T>
bool State<T>::replace(Frame<T> *f){
And... another class.
Faced the same issue post Firefox update to 29.0.1, this is also listed out here https://bugzilla.mozilla.org/show_bug.cgi?id=947728
Solutions:
They(Mozilla guys) have fixed this by introducing support for "-moz-appearance" for <input type="number">.
You just need to have a style associated with your input field with "-moz-appearance:textfield;".
I prefer the CSS way E.g.:-
.input-mini{
-moz-appearance:textfield;}
Or
You can do it inline as well:
<input type="number" style="-moz-appearance: textfield">
var index = ctx.Items.FirstOrDefault(item => Equals(item.Value, Settings.Default.Format_Encoding));
ctx.SelectedIndex = ctx.Items.IndexOf(index);
OR
foreach (var listItem in ctx.Items)
listItem.Selected = Equals(listItem.Value as Encoding, Settings.Default.Format_Encoding);
Should work.. especially when using extended RAD controls in which FindByText/Value doesn't even exist!
If you need to download only text file into String you can use this simple way, Swift 5:
let list = try? String(contentsOf: URL(string: "https://example.com/file.txt")!)
In case you want non optional result or error handling:
do {
let list = try String(contentsOf: URL(string: "https://example.com/file.txt")!)
}
catch {
// Handle error here
}
You should know that network operations may take some time, to prevent it from running in main thread and locking your UI, you may want to execute the code asynchronously, for example:
DispatchQueue.global().async {
let list = try? String(contentsOf: URL(string: "https://example.com/file.txt")!)
}
Our web app requires a fixed header. We are fortunate in that we only have to support the latest browsers, but Safari's behavior in this area caused us a real problem.
The best fix, as others have pointed out, is to write our own scrolling code. However, we can't justify that effort to fix a problem that occurs only on iOS. It makes more sense to hope that Apple may fix this problem, especially since, as QuirksMode suggests, Apple now stands alone in their interpretation of "position:fixed".
http://www.quirksmode.org/blog/archives/2013/12/position_fixed_1.html
What worked for us is to toggle between "position:fixed" and "position:absolute" depending on whether the user has zoomed. This replaces our "floating" header with predictable behavior, which is important for usability. When zoomed, the behavior is not what we want, but the user can easily work around this by reversing the zoom.
// On iOS, "position: fixed;" is not supported when zoomed, so toggle "position: absolute;".
header = document.createElement( "HEADER" );
document.body.appendChild( header );
if( navigator.userAgent.match( /iPad/i ) || navigator.userAgent.match( /iPhone/i )) {
addEventListener( document.body, function( event ) {
var zoomLevel = (( Math.abs( window.orientation ) === 90 ) ? screen.height : screen.width ) / window.innerWidth;
header.style.position = ( zoomLevel > 1 ) ? "absolute" : "fixed";
});
}
Not directly. But you can use extensions such as LESS to help you achieve the same.
It is majorly because of weak connection between mysql client and remote mysql server.
In my case it is because of flaky VPN connection.
have a look at vsnprintf as this will do what ya want http://www.cplusplus.com/reference/clibrary/cstdio/vsprintf/
you will have to init the va_list arg array first, then call it.
Example from that link: /* vsprintf example */
#include <stdio.h>
#include <stdarg.h>
void Error (char * format, ...)
{
char buffer[256];
va_list args;
va_start (args, format);
vsnprintf (buffer, 255, format, args);
//do something with the error
va_end (args);
}
Tried the following code, worked OK on IE6 on WinXP Pro SP3.
function Resize(imgId)
{
var img = document.getElementById(imgId);
var w = img.width, h = img.height;
w /= 2; h /= 2;
img.width = w; img.height = h;
}
Also OK in FF3 and Opera 9.26.
For IE: window.close(); and self.close(); should work fine.
If you want just open the IE browser and type
javascript:self.close() and hit enter, it should ask you for a prompt.
Note: this method doesn't work for Chrome or Firefox.
For nested structures of different depth, i.e. {node: {leaf: 4}, leaf: 1}, this will work (using lodash or underscore):
function getMaxValue(d){
if(typeof d === "number") {
return d;
} else if(typeof d === "object") {
return _.max(_.map(_.keys(d), function(key) {
return getMaxValue(d[key]);
}));
} else {
return false;
}
}
The second one is fastest. Using strlen will be close if the string is indeed empty, but strlen will always iterate through every character of the string, so if it is not empty, it will do much more work than you need it to.
As James mentioned, the third option wipes the string out before checking, so the check will always succeed but it will be meaningless.
If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):
bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
bbox = mtransforms.Bbox.union(bboxes)
bottom = bbox.y0
x, y = self.label.get_position()
self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))
You can set the label position independently of the ticks by using:
ax.xaxis.set_label_coords(x0, y0)
that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.
Make one or both of the terms a floating point number, like so:
4.0/100.0
Alternatively, turn on the feature that will be default in Python 3.0, 'true division', that does what you want. At the top of your module or script, do:
from __future__ import division
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
For Https
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^(.*)$ http%1://www.%{HTTP_HOST}/$1 [R=301,L]
It seems like you have it worked out, but for others looking for this answer, an easy way to do this is by printing to stderr. You can do that like this:
from __future__ import print_function # In python 2.7
import sys
@app.route('/button/')
def button_clicked():
print('Hello world!', file=sys.stderr)
return redirect('/')
Flask will display things printed to stderr in the console. For other ways of printing to stderr, see this stackoverflow post

I know the struggle man! But I recently had it pretty much working with Workerman. If you have not stumbled upon this php framework then you better check this out!
Well, Workerman is an asynchronous event driven PHP framework for easily building fast, scalable network applications. (I just copied and pasted that from their website hahahah http://www.workerman.net/en/)
The easy way to explain this is that when it comes web socket programming all you really need to have is to have 2 files in your server or local server (wherever you are working at).
server.php (source code which will respond to all the client's request)
client.php/client.html (source code which will do the requesting stuffs)
So basically, you right the code first on you server.php and start the server. Normally, as I am using windows which adds more of the struggle, I run the server through this command --> php server.php start
Well if you are using xampp. Here's one way to do it. Go to wherever you want to put your files. In our case, we're going to the put the files in
C:/xampp/htdocs/websocket/server.php
C:/xampp/htdocs/websocket/client.php or client.html
Assuming that you already have those files in your local server. Open your Git Bash or Command Line or Terminal or whichever you are using and download the php libraries here.
https://github.com/walkor/Workerman
https://github.com/walkor/phpsocket.io
I usually download it via composer and just autoload those files in my php scripts.
And also check this one. This is really important! You need this javascript libary in order for you client.php or client.html to communicate with the server.php when you run it.
https://github.com/walkor/phpsocket.io/tree/master/examples/chat/public/socket.io-client
I just copy and pasted that socket.io-client folder on the same level as my server.php and my client.php
Here is the server.php sourcecode
<?php
require __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
use PHPSocketIO\SocketIO;
// listen port 2021 for socket.io client
$io = new SocketIO(2021);
$io->on('connection', function($socket)use($io){
$socket->on('send message', function($msg)use($io){
$io->emit('new message', $msg);
});
});
Worker::runAll();
And here is the client.php or client.html sourcecode
<!DOCTYPE html>
<html>
<head>
<title>Chat</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div id="chat-messages" style="overflow-y: scroll; height: 100px; "></div>
<input type="text" class="message">
</body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="socket.io-client/socket.io.js"></script>
<script>
var socket = io.connect("ws://127.0.0.1:2021");
$('.message').on('change', function(){
socket.emit('send message', $(this).val());
$(this).val('');
});
socket.on('new message', function(data){
$('#chat-messages').append('<p>' + data +'</p>');
});
</script>
</html>
Once again, open your command line or git bash or terminal where you put your server.php file. So in our case, that is C:/xampp/htdocs/websocket/ and typed in php server.php start and press enter.
Then go to you browser and type http://localhost/websocket/client.php to visit your site. Then just type anything to that textbox and you will see a basic php websocket on the go!
You just need to remember. In web socket programming, it just needs a server and a client. Run the server code first and the open the client code. And there you have it! Hope this helps!
It is not advised to call ViewDidLoad or ViewWillAppear by yourself.
In the ViewDidLoad include a loadData() function to prepare the data. This is executed in the initial run.
When you want to reload, call loadData() again to get the data from model. In a tableView call reloadData() or in a regular view setNeedsDisplay().
//Multiple selection:
private void clbsec(CheckedListBox clb, string text)
{
for (int i = 0; i < clb.Items.Count; i++)
{
if(text == clb.Items[i].ToString())
{
clb.SetItemChecked(i, true);
}
}
}
using ==>
clbsec(checkedListBox1,"michael");
or
clbsec(checkedListBox1,textBox1.Text);
or
clbsec(checkedListBox1,dataGridView1.CurrentCell.Value.toString());
You can use fstat() to get the file's inode by struct stat. Then, using readdir() you can compare the inode you found with those that exist (struct dirent) in a directory (assuming that you know the directory, otherwise you'll have to search the whole filesystem) and find the corresponding file name. Nasty?
Gradle wrapper needs to be built. Try running gradle wrapper --gradle-version 2.13 Remember to change 2.13 to your gradle version number. After running this command, you should see new scripts added to your project folder. You should be able to run the wrapper with ./gradlew build to build your code. Please refer to this guid for more information https://spring.io/guides/gs/gradle/.
document.getElementById('Id').value='new value';
https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById
May be your dependencies not build correctly. Check compilation issue in project.
Clean and rebuild project.
For maven project:
mvn clean install
For gradle projects:
gradle clean build or gradlew clean build
If you want to test explicitly for valid JSON (as opposed to the absence of the returned value false), then you can use a parsing approach as described here.
resolve.alias should work exactly the way you described, so I'm providing this as an answer to help mitigate any confusion that may result from the suggestion in the original question that it does not work.
a resolve configuration like the one below will give you the desired results:
// used to resolve absolute path to project's root directory (where web pack.config.js should be located)
var path = require( 'path' );
...
{
...
resolve: {
// add alias for application code directory
alias:{
mydir: path.resolve( __dirname, 'path', 'to', 'mydir' )
},
extensions: [ '', '.js' ]
}
}
require( 'mydir/myfile.js' ) will work as expected. If it does not, there must be some other issue.
If you have multiple modules that you want to add to the search path, resolve.root makes sense, but if you just want to be able to reference components within your application code without relative paths, alias seems to be the most straight-forward and explicit.
An important advantage of alias is that it gives you the opportunity to namespace your requires which can add clarity to your code; just like it is easy to see from other requires what module is being referenced, alias allows you to write descriptive requires that make it obvious you're requiring internal modules, e.g. require( 'my-project/component' ). resolve.root just plops you into the desired directory without giving you the opportunity to namespace it further.
You can use closures to pass parameters:
iframe.document.addEventListener('click', function(event) {clic(this.id);}, false);
However, I recommend that you use a better approach to access your frame (I can only assume that you are using the DOM0 way of accessing frame windows by their name - something that is only kept around for backwards compatibility):
document.getElementById("myFrame").contentDocument.addEventListener(...);
You can use the extract_html field of the summary REST endpoint for this: e.g. https://en.wikipedia.org/api/rest_v1/page/summary/Cat.
Note: This aims to simply the content a bit by removing most of the pronunciations, mainly in parentheses in some cases.
Using Socket.IO 1.x:
Get array of the connected clients:
io.engine === io.eio // => true
Object.keys(io.engine.clients) // => [ 'US8AxrUrrDF_G7ZUAAAA', 'Ov2Ca24Olkhf2NHbAAAB' ]
Object.keys(io.eio.clients) // => [ 'US8AxrUrrDF_G7ZUAAAA', 'Ov2Ca24Olkhf2NHbAAAB' ]
Get the number of connected clients:
io.engine.clientsCount // => 2
io.eio.clientsCount // => 2
It's just a variable name, and it's conventional in python to use _ for throwaway variables. It just indicates that the loop variable isn't actually used.

You can completely control the execution of javascript functions (and pass variables between them) using custom jQuery events....I was told that this wasn't possible all over these forums, but I got something working that does exactly that (even using an ajax call).
Here's the answer (IMPORTANT: it's not the checked answer but rather the answer by me "Emile"):
How to get a variable returned across multiple functions - Javascript/jQuery
You should inspect full trace very carefully,
I've a server socket application and fixed a java.net.SocketException: Connection reset case.
In my case it happens while reading from a clientSocket Socket object which is closed its connection because of some reason. (Network lost,firewall or application crash or intended close)
Actually I was re-establishing connection when I got an error while reading from this Socket object.
Socket clientSocket = ServerSocket.accept();
is = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
int readed = is.read(); // WHERE ERROR STARTS !!!
The interesting thing is for my JAVA Socket if a client connects to my ServerSocket and close its connection without sending anything is.read() is being called repeatedly.It seems because of being in an infinite while loop for reading from this socket you try to read from a closed connection.
If you use something like below for read operation;
while(true)
{
Receive();
}
Then you get a stackTrace something like below on and on
java.net.SocketException: Socket is closed
at java.net.ServerSocket.accept(ServerSocket.java:494)
What I did is just closing ServerSocket and renewing my connection and waiting for further incoming client connections
String Receive() throws Exception
{
try {
int readed = is.read();
....
}catch(Exception e)
{
tryReConnect();
logit(); //etc
}
//...
}
This reestablises my connection for unknown client socket losts
private void tryReConnect()
{
try
{
ServerSocket.close();
//empty my old lost connection and let it get by garbage col. immediately
clientSocket=null;
System.gc();
//Wait a new client Socket connection and address this to my local variable
clientSocket= ServerSocket.accept(); // Waiting for another Connection
System.out.println("Connection established...");
}catch (Exception e) {
String message="ReConnect not successful "+e.getMessage();
logit();//etc...
}
}
I couldn't find another way because as you see from below image you can't understand whether connection is lost or not without a try and catch ,because everything seems right . I got this snapshot while I was getting Connection reset continuously.
If I wish to submit a http get request using System.Net.HttpClient there seems to be no api to add parameters, is this correct?
Yes.
Is there any simple api available to build the query string that doesn't involve building a name value collection and url encoding those and then finally concatenating them?
Sure:
var query = HttpUtility.ParseQueryString(string.Empty);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
string queryString = query.ToString();
will give you the expected result:
foo=bar%3c%3e%26-baz&bar=bazinga
You might also find the UriBuilder class useful:
var builder = new UriBuilder("http://example.com");
builder.Port = -1;
var query = HttpUtility.ParseQueryString(builder.Query);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
builder.Query = query.ToString();
string url = builder.ToString();
will give you the expected result:
http://example.com/?foo=bar%3c%3e%26-baz&bar=bazinga
that you could more than safely feed to your HttpClient.GetAsync method.
Since the user can go into the OS menu and select paste using their mouse, there is no safe event that will trigger this for you. The only way I found that always works is to have a setInterval that checks if the input value has changed:
var inp = $('#input'),
val = saved = inp.val(),
tid = setInterval(function() {
val = inp.val();
if ( saved != val ) {
console.log('#input has changed');
saved = val;
},50);
You can also set this up using a jQuery special event.
I prefer doing a "PAD" to the data. MySql calls it LPAD, but you can work your way around to doing the same thing in SQL Server.
ORDER BY REPLACE(STR(ColName, 3), SPACE(1), '0')
This formula will provide leading zeroes based on the Column's length of 3. This functionality is very useful in other situations outside of ORDER BY, so that is why I wanted to provide this option.
Results: 1 becomes 001, and 10 becomes 010, while 100 remains the same.
you can try like that. try: self.assertRaises(None,function,arg1, arg2) except: pass if you don't put code inside try block it will through exception' AssertionError: None not raised " and test case will be failed. Test case will be pass if put inside try block which is expected behaviour.
1.
Type t = typeof(obj1);
if (t == typeof(int))
This is illegal, because typeof only works on types, not on variables. I assume obj1 is a variable. So, in this way typeof is static, and does its work at compile time instead of runtime.
2.
if (obj1.GetType() == typeof(int))
This is true if obj1 is exactly of type int. If obj1 derives from int, the if condition will be false.
3.
if (obj1 is int)
This is true if obj1 is an int, or if it derives from a class called int, or if it implements an interface called int.
There are three different setups that providing a stack to run an application on (This will help us to recognize what a container is and what makes it so much powerful than other solutions):
1) Traditional Servers(bare metal)
2) Virtual machines (VMs)
3) Containers
1) Traditional server stack consist of a physical server that runs an operating system and your application.
Advantages:
Utilization of raw resources
Isolation
Disadvantages:
2) The VM stack consist of a physical server which runs an operating system and a hypervisor that manages your virtual machine, shared resources, and networking interface. Each Vm runs a Guest Operating System, an application or set of applications.
Advantages:
Disadvantages:
3) The Container Setup, the key difference with other stack is container-based virtualization uses the kernel of the host OS to rum multiple isolated guest instances. These guest instances are called as containers. The host can be either a physical server or VM.
Advantages:
Disadvantages:
By comparing the container setup with its predecessors, we can conclude that containerization is the fastest, most resource effective, and most secure setup we know to date. Containers are isolated instances that run your application. Docker spin up the container in a way, layers get run time memory with default storage drivers(Overlay drivers) those run within seconds and copy-on-write layer created on top of it once we commit into the container, that powers the execution of containers. In case of VM's that will take around a minute to load everything into the virtualize environment. These lightweight instances can be replaced, rebuild, and moved around easily. This allows us to mirror the production and development environment and is tremendous help in CI/CD processes. The advantages containers can provide are so compelling that they're definitely here to stay.

Additionally,I have found this on google and I wanted to share this to those who are still searching for answers. (for global)
I think you have to be using user32.dll
protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
if (m.Msg == 0x0312)

/* Note that the three lines below are not needed if you only want to register one hotkey.
* The below lines are useful in case you want to register multiple keys, which you can use a switch with the id as argument, or if you want to know which key/modifier was pressed for some particular reason. */
Keys key = (Keys)(((int)m.LParam >> 16) & 0xFFFF); // The key of the hotkey that was pressed.
KeyModifier modifier = (KeyModifier)((int)m.LParam & 0xFFFF); // The modifier of the hotkey that was pressed.
int id = m.WParam.ToInt32(); // The id of the hotkey that was pressed.

This is the most up-to-date solution without error suppression:
if (!is_dir('path/to/directory')) {
mkdir('path/to/directory');
}
If your image is too large (and you can't/don't want to just made the image smaller), a combination of the first two answers works great.
addButton.imageView?.contentMode = .scaleAspectFit
addButton.imageEdgeInsets = UIEdgeInsetsMake(15.0, 15.0, 15.0, 5.0)
Unless you get the image insets just right, the image will be skewed without changing the contentMode.
You could also use a regular expression:
/[?&]q=/.test(location.search)
toFixed() method formats a number using fixed-point notation. Read MDN Web Docs for full reference.
var fval = 4;
console.log(fval.toFixed(2)); // prints 4.00
Backup a single table with its data from a database in sql server 2008
SELECT * INTO [dbo].[tbl_NewTable]
FROM [dbo].[tbl_OldTable]
The error is because there is some non-ascii character in the dictionary and it can't be encoded/decoded. One simple way to avoid this error is to encode such strings with encode() function as follows (if a is the string with non-ascii character):
a.encode('utf-8').strip()
Execute: sudo gedit ~/.bashrc add
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export JAVA_HOME
PATH=$PATH:$JAVA_HOME
export PATH
export ANDROID_HOME=~/Android/Sdk
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
and
source ~/.bashrc
Just to correct and slightly extend Scott Wilson answer.
You can use data.table's setnames function on data.frames too.
Do not expect speed up of the operation but you can expect the setnames to be more efficient for memory consumption as it updates column names by reference. This can be tracked with address function, see below.
library(data.table)
set.seed(123)
n = 1e8
df = data.frame(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(df)
#[1] "0x208f9f00"
colnames(df) <- c("good", "better")
address(df)
#[1] "0x208fa1d8"
rm(df)
dt = data.table(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(dt)
#[1] "0x535c830"
setnames(dt, c("good", "better"))
address(dt)
#[1] "0x535c830"
rm(dt)
So if you are hitting your memory limits you may consider to use this one instead.
You can disable and re-enable the foreign key constraints before and after deleting:
alter table MyOtherTable nocheck constraint all
delete from MyTable
alter table MyOtherTable check constraint all
I just ran into the same issue for Ubuntu 13.04. These commands removed Postgres 9.1:
sudo apt-get purge postgresql
sudo apt-get autoremove postgresql
It occurs to me that perhaps only the second command is necessary, but from there I was able to install Postgres 9.2 (sudo apt-get install postgresql-9.2).
Standard class java.util.ArrayList is resizable array, growing when new elements added.
You can use Extend to add new objects to an existing one.
Here is an example using HTML:
<input type="button" value="click me" onclick="this.style.color='#000000';
this.style.backgroundColor = '#ffffff'" />
And here is an example using JavaScript:
document.getElementById("button").bgcolor="#Insert Color Here";
Another option could be to use Linq and aggregate random chars into a stringbuilder.
var chars = "abcdefghijklmnopqrstuvwxyz123456789".ToArray();
string pw = Enumerable.Range(0, passwordLength)
.Aggregate(
new StringBuilder(),
(sb, n) => sb.Append((chars[random.Next(chars.Length)])),
sb => sb.ToString());
It's a value type large enough to store a memory address as used in native or unsafe code, but not directly usable as a memory address in safe managed code.
You can use IntPtr.Size to find out whether you're running in a 32-bit or 64-bit process, as it will be 4 or 8 bytes respectively.
If all that you need is details of User, for Spring Version 4.x you can use @AuthenticationPrincipal and @EnableWebSecurity tag provided by Spring as shown below.
Security Configuration Class:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
...
}
Controller method:
@RequestMapping("/messages/inbox")
public ModelAndView findMessagesForUser(@AuthenticationPrincipal User user) {
...
}
There is an assertNotEquals in JUnit 4.11: https://github.com/junit-team/junit/blob/master/doc/ReleaseNotes4.11.md#improvements-to-assert-and-assume
import static org.junit.Assert.assertNotEquals;
If Java is installed on the target machine, there is no need to create an .exe file. A .jar file should be sufficient.
The stdout of the process started by the docker container is available through the docker logs $containerid command (use -f to keep it going forever). Another option would be to stream the logs directly through the docker remote API.
For accessing log files (only if you must, consider logging to stdout or other standard solution like syslogd) your only real-time option is to configure a volume (like Marcus Hughes suggests) so the logs are stored outside the container and available for processing from the host or another container.
If you do not need real-time access to the logs, you can export the files (in tar format) with docker export
To make the code portable to any system, I would use:
public static String newline = System.getProperty("line.separator");
This is important because different OSs use different notations for newline: Windows uses "\r\n", Classic Mac uses "\r", and Mac and Linux both use "\n".
Commentors - please correct me if I'm wrong on this...
In a case where the table isnt of fixed size, below line worked for me:
style="width:110px; word-break: break-all;"
You can also use this lightweight npm package called absorb
It is 27 lines of code, 1kb and uses recursion to perform deep object merges.
var absorb = require('absorb');
var obj1, obj2;
obj1 = { foo: 123, bar: 456 };
obj2 = { bar: 123, key: 'value' }
absorb(obj1, obj2);
console.log(obj1); // Output: { foo: 123, bar: 123, key: 'value' }
You can also use it to make a clone or only transfer values if they don't exist in the source object, how to do this is detailed in the link provided.
Just complementing @yuchaozh answer above that helped me solve it. (I don't have rep to comment)
Run this to know which java version you have
ls /Library/Java/JavaVirtualMachines/
You'll get an output like:
jdk1.8.0_111.jdk
Replace with your Java version and run this command to export the correct path.
export JAVA_HOME="/Library/Java/JavaVirtualMachines/<YOUR_JAVA_VERSION>/Contents/Home"

Only methods with WebGet can be accessed from browser IE ; you can access other http verbs by just typing address
You can either try Restful service startup kit of codeples or use fiddler to test your other http verbs
One example, if you need to reference/join the same data set multiple times you can do so by defining a CTE. Therefore, it can be a form of code re-use.
An example of self referencing is recursion: Recursive Queries Using CTE
For exciting Microsoft definitions Taken from Books Online:
A CTE can be used to:
Create a recursive query. For more information, see Recursive Queries Using Common Table Expressions.
Substitute for a view when the general use of a view is not required; that is, you do not have to store the definition in metadata.
Enable grouping by a column that is derived from a scalar subselect, or a function that is either not deterministic or has external access.
Reference the resulting table multiple times in the same statement.
Using query-string module is the recommended one when you need a module to parse your query string in ease.
componentWillMount() {
var query = queryString.parse(this.props.location.search);
if (query.token) {
window.localStorage.setItem("jwt", query.token);
store.dispatch(push("/"));
}
}
Here, I am redirecting back to my client from Node.js server after successful Google-Passport authentication, which is redirecting back with token as query param.
I am parsing it with query-string module, saving it and updating the query params in the url with push from react-router-redux.
Following are few libraries to create PDF with Java:
I have used iText for genarating PDF's with a little bit of pain in the past.
Or you can try using FOP: FOP is an XSL formatter written in Java. It is used in conjunction with an XSLT transformation engine to format XML documents into PDF.
You can create a custom link as described here using a small jQuery script
$('.linkPinIt').click(function(){
var url = $(this).attr('href');
var media = $(this).attr('data-image');
var desc = $(this).attr('data-desc');
window.open("//www.pinterest.com/pin/create/button/"+
"?url="+url+
"&media="+media+
"&description="+desc,"_blank","top=0,right=0,width=750,height=320");
return false;
});
this will work for all links with class linkPinItwhich have the image and the description stored in the HTML 5 data attributes data-image and data-desc
<a href="https%3A%2F%2Fwww.flickr.com%2Fphotos%2Fkentbrew%2F6851755809%2F"
data-image="https%3A%2F%2Fc4.staticflickr.com%2F8%2F7027%2F6851755809_df5b2051c9_b.jpg"
data-desc="Title for Pinterest Photo" class="linkPinIt">

</a>

In my case, I'm using j-hipster and I had to do ./mvnw clean to overcome this warning.
In Jan2018 the only solution worked for me:
<?php
if (ob_get_level() == 0) ob_start();
for ($i = 0; $i<10; $i++){
echo "<br> Line to show.";
echo str_pad('',4096)."\n";
ob_flush();
flush();
sleep(2);
}
echo "Done.";
ob_end_flush();
?>
IIF is the same as CASE WHEN <Condition> THEN <true part> ELSE <false part> END. The query plan will be the same. It is, perhaps, "syntactical sugar" as initially implemented.
CASE is portable across all SQL platforms whereas IIF is SQL SERVER 2012+ specific.
