If it's a server socket, you should call listen()
on your socket, and then getsockname()
to find the port number on which it is listening:
struct sockaddr_in sin;
socklen_t len = sizeof(sin);
if (getsockname(sock, (struct sockaddr *)&sin, &len) == -1)
perror("getsockname");
else
printf("port number %d\n", ntohs(sin.sin_port));
As for the IP address, if you use INADDR_ANY
then the server socket can accept connections to any of the machine's IP addresses and the server socket itself does not have a specific IP address. For example if your machine has two IP addresses then you might get two incoming connections on this server socket, each with a different local IP address. You can use getsockname()
on the socket for a specific connection (which you get from accept()
) in order to find out which local IP address is being used on that connection.
You are having this problem because you are attempting to console log app.address() before the connection has been made. You just have to be sure to console log after the connection is made, i.e. in a callback or after an event signaling that the connection has been made.
Fortunately, the 'listening' event is emitted by the server after the connection is made so just do this:
var express = require('express');
var http = require('http');
var app = express();
var server = http.createServer(app);
app.get('/', function(req, res) {
res.send("Hello World!");
});
server.listen(3000, 'localhost');
server.on('listening', function() {
console.log('Express server started on port %s at %s', server.address().port, server.address().address);
});
This works just fine in nodejs v0.6+ and Express v3.0+.
I also needed what you've been searching for and did some research.
I found JSC3D (https://code.google.com/p/jsc3d/). It's a project written entirely in Javascript and uses the HTML canvas. It has been tested for Opera, Chrome, Firefox, Safari, IE9 and more.
Then you have services as p3d.in and Sketchfab that give you a nice reader to view 3D models on a web page: they use HTML5 and WebGL. They both have a free version.
I think another way is to use recursion. Here is my code:
def gcd(a, b):
if a > b:
c = a - b
gcd(b, c)
elif a < b:
c = b - a
gcd(a, c)
else:
return a
From your example it seems reasonable to assume that the siteIP
column is determined by the siteName
column (that is, each site has only one siteIP
). If this is indeed the case, then there is a simple solution using group by
:
select
sites.siteName,
sites.siteIP,
max(history.date)
from sites
inner join history on
sites.siteName=history.siteName
group by
sites.siteName,
sites.siteIP
order by
sites.siteName;
However, if my assumption is not correct (that is, it is possible for a site to have multiple siteIP
), then it is not clear from you question which siteIP
you want the query to return in the second column. If just any siteIP
, then the following query will do:
select
sites.siteName,
min(sites.siteIP),
max(history.date)
from sites
inner join history on
sites.siteName=history.siteName
group by
sites.siteName
order by
sites.siteName;
You could quickly read it in, and increment a counter, just use a loop to increment, doing nothing with the text.
brew switch libfoo mycopy
You can use brew switch
to switch between versions of the same package, if it's installed as versioned subdirectories under Cellar/<packagename>/
This will list versions installed ( for example I had Cellar/sdl2/2.0.3
, I've compiled into Cellar/sdl2/2.0.4
)
brew info sdl2
Then to switch between them
brew switch sdl2 2.0.4
brew info
Info now shows *
next to the 2.0.4
To install under Cellar/<packagename>/<version>
from source you can do for example
cd ~/somewhere/src/foo-2.0.4
./configure --prefix $(brew --Cellar)/foo/2.0.4
make
check where it gets installed with
make install -n
if all looks correct
make install
Then from cd $(brew --Cellar)
do the switch between version.
I'm using brew version 0.9.5
Your actual code may return an error based on the format of the file path

Given a floating point value, we can round it trivially with printf:
# round $1 to $2 decimal places
round() {
printf "%.{$2:-0}f" "$1"
}
Then,
# do some math, bc style
math() {
echo "$*" | bc -l
}
$ echo "Pi, to five decimal places, is $(round $(math "4*a(1)") 5)"
Pi, to five decimal places, is 3.14159
Or, to use the original request:
$ echo "3/2, rounded to the nearest integer, is $(round $(math "3/2") 0)"
3/2, rounded to the nearest integer, is 2
I'm Daniel Stenberg.
I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.
I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.
Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.
Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.
Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.
At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.
Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.
Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?
Yes. So insanely much.
But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.
We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.
Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.
Yeah. For real.
Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.
But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.
curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.
I needed to use element.attr('form')
instead of element.form
.
I use Firefox on Fedora 12.
I've seen this same problem when my application depended on a referenced assembly that was not present on the deployment machine. I'm not sure what you mean by "referencing DotNetBar out of the install directory" - make sure it's set to CopyLocal=true in your project, or exists at the same full path on both your development and production machine.
You can use this code:
<Button
android:id="@+id/img_sublist_carat"
android:layout_width="70dp"
android:layout_height="68dp"
android:layout_centerVertical="true"
android:layout_marginLeft="625dp"
android:contentDescription=""
android:background="@drawable/img_sublist_carat_selector"
android:visibility="visible" />
(Selector File) img_sublist_carat_selector.xml:
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="@drawable/img_sublist_carat_highlight" />
<item android:state_pressed="true"
android:drawable="@drawable/img_sublist_carat_highlight" />
<item android:drawable="@drawable/img_sublist_carat_normal" />
</selector>
2020 solution:
I wrote a PHP function which uses the Vimeo Oembed API.
/**
* Get Vimeo.com video thumbnail URL
*
* Set the referer parameter if your video is domain restricted.
*
* @param int $videoid Video id
* @param URL $referer Your website domain
* @return bool/string Thumbnail URL or false if can't access the video
*/
function get_vimeo_thumbnail_url( $videoid, $referer=null ){
// if referer set, create context
$ctx = null;
if( isset($referer) ){
$ctxa = array(
'http' => array(
'header' => array("Referer: $referer\r\n"),
'request_fulluri' => true,
),
);
$ctx = stream_context_create($ctxa);
}
$resp = @file_get_contents("https://vimeo.com/api/oembed.json?url=https://vimeo.com/$videoid", False, $ctx);
$resp = json_decode($resp, true);
return $resp["thumbnail_url"]??false;
}
Usage:
echo get_vimeo_thumbnail_url("1084537");
If you just want to know about your screen width, you can just search for "smallest screen width" in your developer options. You can even edit it.
Your @POST
method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:
@XmlRootElement
public class MyJaxBean {
@XmlElement public String param1;
@XmlElement public String param2;
}
Then your @POST
method would look like the following:
@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
System.out.println("param1 = " + input.param1);
System.out.println("param2 = " + input.param2);
}
This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input
in this case. The actual message would look something like:
POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com
{"param1":"hello","param2":"world"}
Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.
HTML <FORM>
The parameters would be annotated using @FormParam:
@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
@FormParam("param2") String param2) {
...
}
The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:
POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25
param1=hello¶m2=world
The content is URL encoded in this case.
If you do not know the names of the FormParam's you can do the following:
@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
...
}
HTTP Headers
You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:
@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
@HeaderParam("param2") String param2) {
...
}
Here's what the HTTP message would look like. Note that this POST does not have a body.
POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world
I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.
HTTP Query Parameters
This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.
@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
@QueryParam("param2") String param2) {
...
}
Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:
POST /create?param1=hello¶m2=world HTTP/1.1
Content-Length: 0
Host: www.example.com
You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.
HTTP Path Parameters
Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:
@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
@PathParam("param2") String param2) {
...
}
The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.
POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com
This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.
As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM
-based HTML pages, then use @FormParam
. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer
implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM
encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.
Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.
Another difference is when async
function returns just Task
instead of Task<T>
then you cannot use
GetFooAsync(...).Result;
Whereas
GetFooAsync(...).GetAwaiter().GetResult();
still works.
I know the example code in the question is for the case Task<T>
, however the question is asked generally.
If what interests you is bitwise operations look here for a brief tutorial : http://weblogs.asp.net/alessandro/archive/2007/10/02/bitwise-operators-in-c-or-xor-and-amp-amp-not.aspx .bitwise operation perform the same operations like the ones exemplified above they just work with binary representation (the operation applies to each individual bit of the value)
If you want logical operation answers are already given.
You need to do two things:
The code:
dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))
library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
geom_ribbon(alpha = 0.35, linetype=0)+
geom_line(aes(linetype=model), size = 1) +
geom_point(aes(shape=model), size=4) +
theme(legend.position=c(.6,0.8)) +
theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
scale_linetype_discrete("Model 1") +
scale_shape_discrete("Model 1") +
scale_colour_discrete("Model 1")
However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
geom_ribbon(alpha=0.2, colour=NA)+
geom_line() +
geom_point() +
facet_wrap(~model)
This should do the job:
diff -rq dir1 dir2
Options explained (via diff(1) man page):
-r
- Recursively compare any subdirectories found.-q
- Output only whether files differ.
$("div.clickable").click(
function(event)
{
window.location = $(this).attr("url");
event.preventDefault();
});
Both the right answer. HTML5 follows strict rules and in HTML5 we can close all the tags. So, it depends on you to use HTML5 or HTML and follow an appropriate answer.
<img src='stackoverflow.png'>
<img src='stackoverflow.png' />
The second property is more appropriate.
Maven

Technically they function the same if you’re using SQL Server AKA T-SQL. If you're using it in stored procedures there is no performance reason to use one over the other. It then comes down to personal preference. I prefer to use <> as it is ANSI compliant.

In regards to @bmasterswizzle
's BRILLIANT answer - more specifically - to @DanRamos

I am NOT quite sure I understand the alteration to the prompt at the end, or...
dd of=/dev/null <&4 & # continuously reads from buffer and dumps to null
but WHATEVER. it works. link light: green?. loves it.
I had the same problem and none of the above answers worked. If you go into the settings (CTRL + ALT + s) and search for project interpreter you will see all of the installed packages. Click the + button at the top right and search for xlrd, then click install package at the bottom left.
I had already done the "pip install xlrd" command from the file location of my python.exe before this, so you may need to do that as well. (you can find the file location by searching it in windows search bar and right click -> open file location, then type cmd into the file explorer address bar)
For iOS 10+, you can use this method for knowing when your notification is clicked irrespective of the state of the app.
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
//Notification clicked
completionHandler()
}
You can use eval(jsonString) if you trust the data in the string, otherwise you'll need to parse it properly - check json.org for some code samples.
// Our initial array
$arr = array("blue", "green", "red", "yellow", "green", "orange", "yellow", "indigo", "red");
print_r($arr);
// Remove the elements who's values are yellow or red
$arr = array_diff($arr, array("yellow", "red"));
print_r($arr);
This is the output from the code above:
Array
(
[0] => blue
[1] => green
[2] => red
[3] => yellow
[4] => green
[5] => orange
[6] => yellow
[7] => indigo
[8] => red
)
Array
(
[0] => blue
[1] => green
[4] => green
[5] => orange
[7] => indigo
)
Now, array_values() will reindex a numerical array nicely, but it will remove all key strings from the array and replace them with numbers. If you need to preserve the key names (strings), or reindex the array if all keys are numerical, use array_merge():
$arr = array_merge(array_diff($arr, array("yellow", "red")));
print_r($arr);
Outputs
Array
(
[0] => blue
[1] => green
[2] => green
[3] => orange
[4] => indigo
)
Your target domain might refuse to send you information. This can work as a filter based on browser agent or any other header information. This is a defense against bots, crawlers or any unwanted applications.
If you are using MVC then it would be more appropriate to use RedirectResult instead of using Response.Redirect.
public ActionResult Index() {
return new RedirectResult("http://www.website.com");
}

You don't have to register an actual BroadcastReceiver as Android's BatteryManager is using a sticky Intent:
IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = registerReceiver(null, ifilter);
int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
float batteryPct = level / (float)scale;
return (int)(batteryPct*100);

If PHP fails, a message will be prompted with the error (missing dll for example).
There's no need for Prototype here: JavaScript has for..in
loops. If you're not sure that no one messed with Object.prototype
, check hasOwnProperty()
as well, ie
for(var prop in obj) {

doSomethingWith(obj[prop]);
}

A SQLite UDF in PHP/PDO for the REGEXP
keyword that mimics the behavior in MySQL:
$pdo->sqliteCreateFunction('regexp',
function ($pattern, $data, $delimiter = '~', $modifiers = 'isuS')
{
if (isset($pattern, $data) === true)
{
return (preg_match(sprintf('%1$s%2$s%1$s%3$s', $delimiter, $pattern, $modifiers), $data) > 0);
}
return null;
}
);
The u
modifier is not implemented in MySQL, but I find it useful to have it by default. Examples:
SELECT * FROM "table" WHERE "name" REGEXP 'sql(ite)*';
SELECT * FROM "table" WHERE regexp('sql(ite)*', "name", '#', 's');
If either $data
or $pattern
is NULL, the result is NULL - just like in MySQL.
here's it, it WORKS 100%
char* appending(char *cArr, const char c)

Easier way:
#required_number = 18
required_number=input("Insert a number: ")
while required_number != 18
print("Oops! Something is wrong")
required_number=input("Try again: ")
if required_number == '18'
print("That's right!")

You can change the separator either by setting a locale or using the DecimalFormatSymbols.
If you want the grouping separator to be a point, you can use an european locale:
NumberFormat nf = NumberFormat.getNumberInstance(Locale.GERMAN);
DecimalFormat df = (DecimalFormat)nf;
Alternatively you can use the DecimalFormatSymbols class to change the symbols that appear in the formatted numbers produced by the format method. These symbols include the decimal separator, the grouping separator, the minus sign, and the percent sign, among others:
DecimalFormatSymbols otherSymbols = new DecimalFormatSymbols(currentLocale);
otherSymbols.setDecimalSeparator(',');
otherSymbols.setGroupingSeparator('.');
DecimalFormat df = new DecimalFormat(formatString, otherSymbols);
currentLocale can be obtained from Locale.getDefault() i.e.:
Locale currentLocale = Locale.getDefault();
Swift version of @onegray's answer
protocol RequestsNavigationPopVerification {
var confirmationTitle: String { get }
var confirmationMessage: String { get }
}
extension RequestsNavigationPopVerification where Self: UIViewController {
var confirmationTitle: String {
return "Go back?"
}
var confirmationMessage: String {
return "Are you sure?"
}
}
final class NavigationController: UINavigationController {
func navigationBar(navigationBar: UINavigationBar, shouldPopItem item: UINavigationItem) -> Bool {
guard let requestsPopConfirm = topViewController as? RequestsNavigationPopVerification else {
popViewControllerAnimated(true)
return true
}
let alertController = UIAlertController(title: requestsPopConfirm.confirmationTitle, message: requestsPopConfirm.confirmationMessage, preferredStyle: .Alert)
alertController.addAction(UIAlertAction(title: "Cancel", style: .Cancel) { _ in
dispatch_async(dispatch_get_main_queue(), {
let dimmed = navigationBar.subviews.flatMap { $0.alpha < 1 ? $0 : nil }
UIView.animateWithDuration(0.25) {
dimmed.forEach { $0.alpha = 1 }
}
})
return
})
alertController.addAction(UIAlertAction(title: "Go back", style: .Default) { _ in
dispatch_async(dispatch_get_main_queue(), {
self.popViewControllerAnimated(true)
})
})
presentViewController(alertController, animated: true, completion: nil)
return false
}
}
Now in any controller, just conform to RequestsNavigationPopVerification
and this behaviour is adopted by default.
It is Safari specific, at least at time of writing, being introduced in Safari 9.0. From the "What's new in Safari?" documentation for Safari 9.0:
Viewport Changes
Viewport meta tags using
"width=device-width"
cause the page to scale down to fit content that overflows the viewport bounds. You can override this behavior by adding"shrink-to-fit=no"
to your meta tag as shown below. The added value will prevent the page from scaling to fit the viewport.
<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">
In short, adding this to the viewport meta tag restores pre-Safari 9.0 behaviour.
Here's a worked visual example which shows the difference upon loading the page in the two configurations.
The red section is the width of the viewport and the blue section is positioned outside the initial viewport (eg left: 100vw
). Note how in the first example the page is zoomed to fit when shrink-to-fit=no
is omitted (thus showing the out-of-viewport content) and the blue content remains off screen in the latter example.
The code for this example can be found at https://codepen.io/davidjb/pen/ENGqpv.
Solved for SSMS 2016.
Had a similar problem, but Intellisense was not in Edit menu.
What seemed to fix it was turning Intellisens on and off, right click on the SQL editor and click 'Intellisense Enabled'. Right click again on 'Intellisense Enabled' to turn it back on again. Ctr Q, I also does this.
This solved the problem, and also I know get the Intellisense on the Edit menu.
If you can compute a unique integer for each element in the array, like this:
tab='0123456789abcdefghijklmnopqrstuvwxyz'
# build the reversed ordinal map
for ((i = 0; i < ${#tab}; i++)); do
declare -g ord_${tab:i:1}=$i
done
function sexy_int() {
local sum=0
local i ch ref
for ((i = 0; i < ${#1}; i++)); do
ch="${1:i:1}"
ref="ord_$ch"
(( sum += ${!ref} ))
done
return $sum
}
sexy_int hello
echo "hello -> $?"
sexy_int world
echo "world -> $?"
then, you can use these integers as array indexes, because Bash always use sparse array, so no need to worry about unused indexes:
array=(a c b f 3 5)
for el in "${array[@]}"; do
sexy_int "$el"
sorted[$?]="$el"
done
echo "${sorted[@]}"
You could use ng-init in an outer div:
<div ng-init="param='value';">
<div ng-controller="BasketController" >
<label>param: {{value}}</label>
</div>
</div>
The parameter will then be available in your controller's scope:
function BasketController($scope) {
console.log($scope.param);
}
Another solution is to make a runtime hook, which will copy(or move) your data (files/folders) to the directory at which the executable is stored. The hook is a simple python file that can almost do anything, just before the execution of your app. In order to set it, you should use the --runtime-hook=my_hook.py
option of pyinstaller. So, in case your data is an images folder, you should run the command:
pyinstaller.py --onefile -F --add-data=images;images --runtime-hook=cp_images_hook.py main.py
The cp_images_hook.py could be something like this:
import sys
import os
import shutil
path = getattr(sys, '_MEIPASS', os.getcwd())
full_path = path+"\\images"
try:
shutil.move(full_path, ".\\images")
except:
print("Cannot create 'images' folder. Already exists.")
Before every execution the images folder is moved to the current directory (from the _MEIPASS folder), so the executable will always have access to it. In that way there is no need to modify your project's code.
You can take advantage of the runtime-hook mechanism and change the current directory, which is not a good practice according to some developers, but it works fine.
The hook code can be found below:
import sys
import os
path = getattr(sys, '_MEIPASS', os.getcwd())
os.chdir(path)
Instead of extrapolating off the ends, you could return the extents of the y_list
. Most of the time your application is well behaved, and the Interpolate[x]
will be in the x_list
. The (presumably) linear affects of extrapolating off the ends may mislead you to believe that your data is well behaved.
Returning a non-linear result (bounded by the contents of x_list
and y_list
) your program's behavior may alert you to an issue for values greatly outside x_list
. (Linear behavior goes bananas when given non-linear inputs!)
Returning the extents of the y_list
for Interpolate[x]
outside of x_list
also means you know the range of your output value. If you extrapolate based on x
much, much less than x_list[0]
or x
much, much greater than x_list[-1]
, your return result could be outside of the range of values you expected.
def __getitem__(self, x):
if x <= self.x_list[0]:
return self.y_list[0]
elif x >= self.x_list[-1]:
return self.y_list[-1]
else:
i = bisect_left(self.x_list, x) - 1
return self.y_list[i] + self.slopes[i] * (x - self.x_list[i])
For me the code:
<form (submit)="addTodo()">_x000D_
<input type="text" [(ngModel)]="text">_x000D_
</form>
_x000D_
throws error, but I added name attribute to input:
<form (submit)="addTodo()">_x000D_
<input type="text" [(ngModel)]="text" name="text">_x000D_
</form>
_x000D_
and it started to work.
You should use a callback parameter:
function Typer(callback)
{
var srcText = 'EXAMPLE ';
var i = 0;
var result = srcText[i];
var interval = setInterval(function() {
if(i == srcText.length - 1) {
clearInterval(interval);
callback();
return;
}
i++;
result += srcText[i].replace("\n", "<br />");
$("#message").html(result);
},
100);
return true;
}
function playBGM () {
alert("Play BGM function");
$('#bgm').get(0).play();
}
Typer(function () {
playBGM();
});
// or one-liner: Typer(playBGM);
So, you pass a function as parameter (callback
) that will be called in that if
before return
.
Also, this is a good article about callbacks.

A partial solution is to wrap the material form field in a custom component and implement the ControlValueAccessor
interface on it. Besides content projection the effect is pretty much the same.
See full example on Stackblitz.
I used FormControl
(reactive forms) inside CustomInputComponent
but FormGroup
or FormArray
should work too if you need a more complex form element.
app.component.html
<form [formGroup]="form" (ngSubmit)="onSubmit()">
<mat-form-field appearance="outline" floatLabel="always" color="primary">
<mat-label>First name</mat-label>
<input matInput placeholder="First name" formControlName="firstName" required>
<mat-hint>Fill in first name.</mat-hint>
<mat-error *ngIf="firstNameControl.invalid && (firstNameControl.dirty || firstNameControl.touched)">
<span *ngIf="firstNameControl.hasError('required')">
You must fill in the first name.
</span>
</mat-error>
</mat-form-field>
<custom-input
formControlName="lastName"
[errorMessages]="errorMessagesForCustomInput"
[hint]="'Fill in last name.'"
[label]="'Last name'"
[isRequired]="true"
[placeholder]="'Last name'"
[validators]="validatorsForCustomInput">
</custom-input>
<button mat-flat-button
color="primary"
type="submit"
[disabled]="form.invalid || form.pending">
Submit
</button>
</form>
custom-input.component.html
<mat-form-field appearance="outline" floatLabel="always" color="primary">
<mat-label>{{ label }}</mat-label>
<input
matInput
[placeholder]="placeholder"
[required]="isRequired"
[formControl]="customControl"
(blur)="onTouched()"
(input)="onChange($event.target.value)">
<mat-hint>{{ hint }}</mat-hint>
<mat-error *ngIf="customControl.invalid && (customControl.dirty || customControl.touched)">
<ng-container *ngFor="let error of errorMessages">
<span *ngFor="let item of error | keyvalue">
<span *ngIf="customControl.hasError(item.key)">
{{ item.value }}
</span>
</span>
</ng-container>
</mat-error>
</mat-form-field>
Try this:
var frm = document.getElementById('search-theme-form') || null;
if(frm) {
frm.action = 'whatever_you_need.ext'
}
If you want a built-in solution for a full comparison with arbitrary dict structures, @Maxx's answer is a good start.

LATERAL
join?The feature was introduced with PostgreSQL 9.3.
Quoting the manual:
Subqueries appearing in
FROM
can be preceded by the key wordLATERAL
. This allows them to reference columns provided by precedingFROM
items. (WithoutLATERAL
, each subquery is evaluated independently and so cannot cross-reference any otherFROM
item.)Table functions appearing in
FROM
can also be preceded by the key wordLATERAL
, but for functions the key word is optional; the function's arguments can contain references to columns provided by precedingFROM
items in any case.
Basic code examples are given there.
A LATERAL
join is more like a correlated subquery, not a plain subquery, in that expressions to the right of a LATERAL
join are evaluated once for each row left of it - just like a correlated subquery - while a plain subquery (table expression) is evaluated once only. (The query planner has ways to optimize performance for either, though.)
Related answer with code examples for both side by side, solving the same problem:
For returning more than one column, a LATERAL
join is typically simpler, cleaner and faster.
Also, remember that the equivalent of a correlated subquery is LEFT JOIN LATERAL ... ON true
:
There are things that a LATERAL
join can do, but a (correlated) subquery cannot (easily). A correlated subquery can only return a single value, not multiple columns and not multiple rows - with the exception of bare function calls (which multiply result rows if they return multiple rows). But even certain set-returning functions are only allowed in the FROM
clause. Like unnest()
with multiple parameters in Postgres 9.4 or later. The manual:
This is only allowed in the
FROM
clause;
So this works, but cannot (easily) be replaced with a subquery:
CREATE TABLE tbl (a1 int[], a2 int[]);
SELECT * FROM tbl, unnest(a1, a2) u(elem1, elem2); -- implicit LATERAL
The comma (,
) in the FROM
clause is short notation for CROSS JOIN
.
LATERAL
is assumed automatically for table functions.
About the special case of UNNEST( array_expression [, ... ] )
:
SELECT
listYou can also use set-returning functions like unnest()
in the SELECT
list directly. This used to exhibit surprising behavior with more than one such function in the same SELECT
list up to Postgres 9.6. But it has finally been sanitized with Postgres 10 and is a valid alternative now (even if not standard SQL). See:
Building on above example:
SELECT *, unnest(a1) AS elem1, unnest(a2) AS elem2
FROM tbl;
Comparison:
dbfiddle for pg 9.6 here
dbfiddle for pg 10 here
For the
INNER
andOUTER
join types, a join condition must be specified, namely exactly one ofNATURAL
,ON
join_condition, orUSING
(join_column [, ...]). See below for the meaning.
ForCROSS JOIN
, none of these clauses can appear.
So these two queries are valid (even if not particularly useful):
SELECT *
FROM tbl t
LEFT JOIN LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t ON TRUE;
SELECT *
FROM tbl t, LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t;
While this one is not:
SELECT *
FROM tbl t
LEFT JOIN LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t;
That's why Andomar's code example is correct (the CROSS JOIN
does not require a join condition) and Attila's is was not.
Have you read about the nohup command?
The DataTable has a collection .Rows
of DataRow elements.
Each DataRow corresponds to one row in your database, and contains a collection of columns.
In order to access a single value, do something like this:
foreach(DataRow row in YourDataTable.Rows)
{
string name = row["name"].ToString();
string description = row["description"].ToString();
string icoFileName = row["iconFile"].ToString();
string installScript = row["installScript"].ToString();
}
The provided examples, using csv
modules, are great! Besides, you can always simply write to a text file using formatted strings, like the following tentative example:
l = [[1, 2], [2, 3], [4, 5]]
out = open('out.csv', 'w')
for row in l:
for column in row:
out.write('%d;' % column)
out.write('\n')
out.close()
I used ;
as separator, because it works best with Excell (one of your requirements).
Hope it helps!
You just add one additional row before you execute the loop. This row contains your CSV file header name.
schema = ['a','b','c','b']
row = 4
generators = ['A','B','C','D']
with open('test.csv','wb') as csvfile:
writer = csv.writer(csvfile, delimiter=delimiter)
# Gives the header name row into csv
writer.writerow([g for g in schema])
#Data add in csv file
for x in xrange(rows):
writer.writerow([g() for g in generators])
I try to avoid floating elements unless the design really needs it. Because you have floated the <li>
they are out of normal flow.
If you add .navigation { text-align:center; }
and change .navigation li { float: left; }
to .navigation li { display: inline-block; }
then entire navigation will be centred.
One caveat to this approach is that display: inline-block;
is not supported in IE6 and needs a workaround to make it work in IE7.
Arrays are not very dynamic in VBScript. You'll have to use the ReDim Preserve statement to grow the existing array so it can accommodate an extra item:
ReDim Preserve yourArray(UBound(yourArray) + 1)
yourArray(UBound(yourArray)) = "Watermelons"
Or maybe
background: transparent !important;
color: #ffffff;
Check out DLRadioButton. You can add and customize radio buttons directly from the Interface Builder. Also works with Swift
perfectly.
Update: version 1.3.2
added square buttons, also improved performance.
Update: version 1.4.4
added multiple selection option, can be used as checkbox as well.
Update: version 1.4.7
added RTL language support.
Use the starts with selector
$('input[name^="pages_title"]').each(function() {
alert($(this).val());
});
Note: In agreement with @epascarello that the better solution is to add a class to the elements and reference that class.
People are confusing about what closure is. Closure is not the inner function. the meaning of closure is act of closing. So inner function is closing over a nonlocal variable which is called free variable.
def counter_in(initial_value=0):
# initial_value is the free variable
def inc(increment=1):
nonlocal initial_value
initial_value += increment
return print(initial_value)
return inc
when you call counter_in()
this will return inc
function which has a free variable initial_value
. So we created a CLOSURE. people call inc
as closure function and I think this is confusing people, people think "ok inner functions are closures". in reality inc
is not a closure, since it is part of the closure, to make life easy, they call it closure function.
myClosingOverFunc=counter_in(2)
this returns inc
function which is closing over the free variable initial_value
. when you invoke myClosingOverFunc
myClosingOverFunc()
it will print 2.
when python sees that a closure sytem exists, it creates a new obj called CELL. this will store only the name of the free variable which is initial_value
in this case. This Cell obj will point to another object which stores the value of the initial_value
.
in our example, initial_value
in outer function and inner function will point to this cell object, and this cell object will be point to the value of the initial_value
.
variable initial_value =====>> CELL ==========>> value of initial_value
So when you call counter_in
its scope is gone, but it does not matter. because variable initial_value
is directly referencing the CELL Obj. and it indirectly references the value of initial_value
. That is why even though scope of outer function is gone, inner function will still have access to the free variable
let's say I want to write a function, which takes in a function as an arg and returns how many times this function is called.
def counter(fn):
# since cnt is a free var, python will create a cell and this cell will point to the value of cnt
# every time cnt changes, cell will be pointing to the new value
cnt = 0
def inner(*args, **kwargs):
# we cannot modidy cnt with out nonlocal
nonlocal cnt
cnt += 1
print(f'{fn.__name__} has been called {cnt} times')
# we are calling fn indirectly via the closue inner
return fn(*args, **kwargs)
return inner
in this example cnt
is our free variable and inner
+ cnt
create CLOSURE. when python sees this it will create a CELL Obj and cnt
will always directly reference this cell obj and CELL will reference the another obj in the memory which stores the value of cnt
. initially cnt=0.
cnt ======>>>> CELL =============> 0
when you invoke the inner function wih passing a parameter counter(myFunc)()
this will increase the cnt by 1. so our referencing schema will change as follow:
cnt ======>>>> CELL =============> 1 #first counter(myFunc)()
cnt ======>>>> CELL =============> 2 #second counter(myFunc)()
cnt ======>>>> CELL =============> 3 #third counter(myFunc)()
this is only one instance of closure. You can create multiple instances of closure with passing another function
counter(differentFunc)()
this will create a different CELL obj from the above. We just have created another closure instance.
cnt ======>> difCELL ========> 1 #first counter(differentFunc)()
cnt ======>> difCELL ========> 2 #secon counter(differentFunc)()
cnt ======>> difCELL ========> 3 #third counter(differentFunc)()
Version 1 is preferable because it is shorter and the compiler will in fact turn it into version 2 - no performance difference whatsoever.
More importantly given we have only 3 properties it might not make a difference, but at what point do you switch from concat to builder?
At the point where you're concatenating in a loop - that's usually when the compiler can't substitute StringBuilder
by itself.
Mike Nereson has this to say on his blog at:
http://blog.codehangover.com/load-multiple-contexts-into-spring/
There are a couple of ways to do this.
1. web.xml contextConfigLocation
Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.
<context-param> <param-name> contextConfigLocation </param-name> <param-value> applicationContext1.xml applicationContext2.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
The above uses carriage returns. Alternatively, yo could just put in a space.
<context-param> <param-name> contextConfigLocation </param-name> <param-value> applicationContext1.xml applicationContext2.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
2. applicationContext.xml import resource
Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.
In
applicationContext.xml
you might have…<!-- hibernate configuration and mappings --> <import resource="applicationContext-hibernate.xml"/> <!-- ldap --> <import resource="applicationContext-ldap.xml"/> <!-- aspects --> <import resource="applicationContext-aspects.xml"/>
Which strategy should you use?
1. I always prefer to load up via web.xml.
Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay
loosely coupled
, so that in the future I can extract a package or vertical layer and move it to its own module.2. If you are loading contexts into a
non-web application
, I would use theimport
resource.
The -m
option is probably what you're looking for:
grep -m 10 PATTERN [FILE]
From man grep
:
-m NUM, --max-count=NUM
Stop reading a file after NUM matching lines. If the input is
standard input from a regular file, and NUM matching lines are
output, grep ensures that the standard input is positioned to
just after the last matching line before exiting, regardless of
the presence of trailing context lines. This enables a calling
process to resume a search.
Note: grep stops reading the file once the specified number of matches have been found!
The following is the more generic solution. It essentially does the same thing (in O(N) order) but on any IEnumberable types and can mixed with types whose property selectors could return null.
public static class LinqExtensions
{
public static T MinBy<T>(this IEnumerable<T> source, Func<T, IComparable> selector)
{
if (source == null)
{
throw new ArgumentNullException(nameof(source));
}
if (selector == null)
{
throw new ArgumentNullException(nameof(selector));
}
return source.Aggregate((min, cur) =>
{
if (min == null)
{
return cur;
}
var minComparer = selector(min);
if (minComparer == null)
{
return cur;
}
var curComparer = selector(cur);
if (curComparer == null)
{
return min;
}
return minComparer.CompareTo(curComparer) > 0 ? cur : min;
});
}
}
Tests:
var nullableInts = new int?[] {5, null, 1, 4, 0, 3, null, 1};
Assert.AreEqual(0, nullableInts.MinBy(i => i));//should pass
I wish I had an answer but I only have Part of one. And I cannot take credit for it but the way to get it is below.
This is a more serious issue than it is being given credit for from the sound of the replies. Everyone is automatically assuming that the content that needs protection is for public consumption. This is not always the case. Sometimes there are legal or contractual reasons that require the site owner to take all possible measures to prevent downloading the file. The most obvious one I can think of has already brought up. The “Action Option Bar” presented by the browser to on almost any file you can left click.
Adobe DRM does nothing about that and worse, Adobe Acrobat cannot even have its own abilities to “Save” blocked as part of the “DRM” protection. This option comes up even in Reader no matter what other security selections you have chosen.
In our case, Adobe Acrobat was purchased solely to provide some degree of protection for their own format. It is hard to believe that Adobe will let you prevent printing, prevent editing, prevent even opening without a password or you can really go all out and use a certificate for your encryption. Yet they have no options to prevent saving at any point, anywhere. Instead offering the consolation of telling you “Don’t worry: The copy they download without your permission will also have the same DRM on it as well”. Unfortunately that was not the sole purpose of the purchase and half a solution is no “solution” at all. There are probably 100 programs that are actually sold just to remove the DRM from Adobe documents and even if not, the point was that the client specified that no downloads be allowed even by users who had access to the private site. Therefore the need to prevent the download to start with is not so hard to understand. While conversion to FLASH may give you the download protection, you lose all the rest. Unless I can find a way to prevent opening, saving etc for a Flash File. Next, is it possible to password protect a Flash file from opening when clicked on?
The “partial fix” that I was finally able to get to work as needed still only disables all the “right click” functions but it does include a nice “Warning Box” where I can explain that the User has already agreed NOT to download, print, save and so on just to have access to the page. I am not sure if I could post the code here or whether it is acceptable to paste links either but a Google search for "Maximus right click" will take you to it. And it was one of several examples, it just happened to be the one I could implement the easiest and worked better than the others. Credit where credit is due.
Another option I was given by someone was a product called “Flipping Book”. And the user above suggestions for “Atalasoft” ( I had already found that and have sent a request for more information). Hopefully it will be “The Solution” and I can implement it in time to help. It seems to me that this is a place where there is an obvious need for a one-step packaged solution and usually "The Laws of Nature" take care of such an Imbalance in short order. Yet my research has taken me through many years of posters all asking for the same thing. Looks like someone would be able to make a nice living off a “simple” way to add a little more "protection" to “PDFs” (or other documents, images etc) for the people who obviously are in need of it. If I find it, and it works, I'm buying it. :>)
I wish I had skills as a programmer because I have some pretty good ideas of ways to implement such a product, unfortunately, I do not know how to put these ideas into practical use.
versionCode
A positive integer used as an internal version number. This number is used only to determine whether one version is more recent than another, with higher numbers indicating more recent versions. This is not the version number shown to users; that number is set by the versionName
setting, below. The Android system uses the versionCode
value to protect against downgrades by preventing users from installing an APK with a lower versionCode
than the version currently installed on their device.
The value is a positive integer so that other apps can programmatically evaluate it, for example to check an upgrade or downgrade relationship. You can set the value to any positive integer you want, however you should make sure that each successive release of your app uses a greater value. You cannot upload an APK to the Play Store with a versionCode
you have already used for a previous version.
versionName
A string used as the version number shown to users. This setting can be specified as a raw string or as a reference to a string resource.
The value is a string so that you can describe the app version as a .. string, or as any other type of absolute or relative version identifier. The versionName
has no purpose other than to be displayed to users.
The obvious answer would be to generate different ids, a separate id for each text box, something like
[int i=0]
<% Using Html.BeginForm()%>
<% For Each item In Model.MyRecords%>
[i++]
<%=Html.TextBox("my_date[i]")%> <br/>
<% Next%>
<% End Using%>
I don't know ASP.net so I just added some general C-like syntax code within square brackets. Translating it to actual ASP.net code shouldn't be a problem.
Then, you have to find a way to generate as many
$('#my_date[i]').datepicker();
as items in your Model.MyRecords
. Again, within square brackets is your counter, so your jQuery function would be something like:
<script type="text/javascript">
$(function() {
$('#my_date1').datepicker();
$('#my_date2').datepicker();
$('#my_date3').datepicker();
...
});
</script>
I recommend CsvHelper from Nuget.
PS: Regarding other more upvoted answers, I'm sorry but adding a reference to Microsoft.VisualBasic
is:
The correct statement should be :
SELECT
student.firstname,
student.lastname,
exam.name,
exam.date,
grade.grade
FROM grade
INNER JOIN student
ON student.studentId = grade.fk_studentId
INNER JOIN exam
ON exam.examId = grade.fk_examId
ORDER BY exam.date
A table is refered to other on the basis of the foreign key relationship defined. You should refer the ids properly if you wish the data to show as queried. So you should refer the id's to the proper foreign keys in the table rather than just on the id which doesn't define a proper relation
Be carreful of the know bug with SwitchCompat
It's a bug with corrupt file in drawable-hdpi on AppCompat https://code.google.com/p/android/issues/detail?id=78262
To fix it, juste override it with this 2 files https://github.com/lopespm/quick-fix-switchcompat-resources Add it on your directory drawable-hdpi
XML
<android.support.v7.widget.SwitchCompat
android:id="@+id/dev_switch_show_dev_only"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
And nothing was necessary on Java
ex.split(',', 2).last
The 2 at the end says: split into 2 pieces, not more.
normally split will cut the value into as many pieces as it can, using a second value you can limit how many pieces you will get. Using ex.split(',', 2)
will give you:
["test1", "test2, test3, test4, test5"]
as an array, instead of:
["test1", "test2", "test3", "test4", "test5"]
Use explode() or preg_split() function to split the string in php with given delimiter
// Use preg_split() function
$string = "123,456,78,000";
$str_arr = preg_split ("/\,/", $string);
print_r($str_arr);
// use of explode
$string = "123,46,78,000";
$str_arr = explode (",", $string);
print_r($str_arr);
I believe spaces must be encoded as:
%20
when used inside URL path component+
when used inside URL query string component or form data (see 17.13.4 Form content types)The following example shows the correct use of rawurlencode
and urlencode
:
echo "http://example.com"
. "/category/" . rawurlencode("latest songs")
. "/search?q=" . urlencode("lady gaga");
Output:
http://example.com/category/latest%20songs/search?q=lady+gaga
What happens if you encode path and query string components the other way round? For the following example:
http://example.com/category/latest+songs/search?q=lady%20gaga
latest+songs
instead of latest songs
q
will contain lady gaga
Factory: The factory you actually create an object inside of the factory and return it.
service: The service you just have a standard function that uses the this keyword to define function.
provider: The provider there’s a $get you define and it can be used to get the object that returns the data.
I am not sure there is a way to do it automatically without javascript.
What you need is something which runs on the browser side to submit your form back to the server when they user makes a selection - hence, javascript.
Also, ensure you have an alternate means (i.e. a submit button) for those who have javascript turned off.
A good example: Combo-Box Viewer
I had even a more sophisticated combo-box yesterday, with this dhtmlxCombo , using ajax to retrieve pertinent values amongst large quantity of data.
Prefix the call with Module2 (ex. Module2.IDLE
). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.
Use cron with find to delete files older than given threshold. For example to delete files that haven't been accessed for at least a week.
find .session/ -atime +7 -exec rm {} \;
netstat -ano
That will show you the PID of the process that is listening on port 80.
After that, open the Task Manager -> Processes tab. From the View -> Select Columns
menu, enable the PID
column, and you will see the name of the process listening on port 80.
I wrote the following function in order to determine if an multidimensional array partially contains a certain value.
function findKeyValue ($array, $needle, $value, $found = false){
foreach ($array as $key => $item){
// Navigate through the array completely.
if (is_array($item)){
$found = $this->findKeyValue($item, $needle, $value, $found);
}
// If the item is a node, verify if the value of the node contains
// the given search parameter. E.G.: 'value' <=> 'This contains the value'
if ( ! empty($key) && $key == $needle && strpos($item, $value) !== false){
return true;
}
}
return $found;
}
Call the function like this:
$this->findKeyValue($array, $key, $value);
The "JavaScript" way:
var lang = navigator.language || navigator.userLanguage; //no ?s necessary
Really you should be doing language detection on the server, but if it's absolutely necessary to know/use via JavaScript, it can be gotten.
I have found a solution with Powershell script that will do it for me.
The script at first stop all containers than remove all containers and then remove images that are named by the user.
Look here http://www.devcode4.com/article/powershell-remove-docker-containers-and-images
To check for the existence of images, exif_imagetype
should be preferred over getimagesize
, as it is much faster.
To suppress the E_NOTICE
, just prepend the error control operator (@
).
if (@exif_imagetype($filename)) {
// Image exist
}
As a bonus, with the returned value (IMAGETYPE_XXX
) from exif_imagetype
we could also get the mime-type or file-extension with image_type_to_mime_type
/ image_type_to_extension
.
I found this worked for me.
import numpy as np
import pandas as pd
df1 = pd.DataFrame({
"Name" : ["Alice", "Bob", "Mallory", "Mallory", "Bob" , "Mallory"] ,
"City" : ["Seattle", "Seattle", "Portland", "Seattle", "Seattle", "Portland"]})
df1['City_count'] = 1
df1['Name_count'] = 1
df1.groupby(['Name', 'City'], as_index=False).count()
You can expand it and have a visulization
T(n) = T(n-1) + T(n-2) <
T(n-1) + T(n-1)
= 2*T(n-1)
= 2*2*T(n-2)
= 2*2*2*T(n-3)
....
= 2^i*T(n-i)
...
==> O(2^n)
If your data has the names grouped as shown then you can use this formula in D2 copied down to get a total against the last entry for each name
=IF((A2=A3)*(B2=B3),"",SUM(C$2:C2)-SUM(D$1:D1))

You can use
start "" "%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"
or
start "" /D "%USERPROFILE%\Desktop\BGInfo" bginfo.exe dc_bginfo.bgi
or
"%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"
or
cd /D "%USERPROFILE%\Desktop\BGInfo"
bginfo.exe dc_bginfo.bgi
Help on commands start and cd is output by executing in a command prompt window help start
or start /?
and help cd
or cd /?
.
But I do not understand why you need a batch file at all for starting the application with the additional parameter. Create a shortcut (*.lnk) on your desktop for this application. Then right click on the shortcut, left click on Properties and append after a space character "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"
as parameter.
Use the EXECUTABLE_OUTPUT_PATH
CMake variable to set the needed path. For details, refer to the online CMake documentation:

This can be done with MySQL, although it's highly unintuitive:
CREATE PROCEDURE p25 (OUT return_val INT)
BEGIN
DECLARE a,b INT;
DECLARE cur_1 CURSOR FOR SELECT s1 FROM t;
DECLARE CONTINUE HANDLER FOR NOT FOUND
SET b = 1;
OPEN cur_1;
REPEAT
FETCH cur_1 INTO a;
UNTIL b = 1
END REPEAT;
CLOSE cur_1;
SET return_val = a;
END;//

I wrote the following procedure for concatenation of several array:
static public byte[] concat(byte[]... bufs) {
if (bufs.length == 0)
return null;
if (bufs.length == 1)
return bufs[0];
for (int i = 0; i < bufs.length - 1; i++) {
byte[] res = Arrays.copyOf(bufs[i], bufs[i].length+bufs[i + 1].length);
System.arraycopy(bufs[i + 1], 0, res, bufs[i].length, bufs[i + 1].length);
bufs[i + 1] = res;
}
return bufs[bufs.length - 1];
}
It uses Arrays.copyOf
My workaround had been using Perl:
find . -type f -print0 | xargs -0 perl -pi -e 's/was/now/g'
Statically typed languages type-check at compile time and the type can NOT change. (Don't get cute with type-casting comments, a new variable/reference is created).
Dynamically typed languages type-check at run-time and the type of an variable CAN be changed at run-time.
try out like this
body {
background: #fff url("!--MIZO-PRO--!") no-repeat center 15px top 15px/100px;
}
/* 100px is the background size */
In Xcode 4 and possibly before, in the run script build phase there is an option "Show enviroment variables in build phase". If selected this will show then on a olive green background in the build log.
Try this
select count(*) from table where cast(col as double) is null;
In simple terms, inside a then
handler function:
A) When x
is a value (number, string, etc):
return x
is equivalent to return Promise.resolve(x)
throw x
is equivalent to return Promise.reject(x)
B) When x
is a Promise that is already settled (not pending anymore):
return x
is equivalent to return Promise.resolve(x)
, if the Promise was already resolved.return x
is equivalent to return Promise.reject(x)
, if the Promise was already rejected.C) When x
is a Promise that is pending:
return x
will return a pending Promise, and it will be evaluated on the subsequent then
. Read more on this topic on the Promise.prototype.then() docs.
As all of the other answers have already said, it's part of ES2015 arrow function syntax. More specifically, it's not an operator, it's a punctuator token that separates the parameters from the body: ArrowFunction : ArrowParameters => ConciseBody
. E.g. (params) => { /* body */ }
.
You can use a character class:
/[^\s\\]/
matches anything that is not a whitespace character nor a \
. Here's another example:
[abc]
means "match a
, b
or c
"; [^abc]
means "match any character except a
, b
or c
".
Maybe you find this simpler

Converting is easy, setting date and time is a little tricky. Here's an example:
Calendar cal = Calendar.getInstance();
cal.set(Calendar.YEAR, 2000);
cal.set(Calendar.MONTH, 0);
cal.set(Calendar.DAY_OF_MONTH, 1);
cal.set(Calendar.HOUR_OF_DAY, 1);
cal.set(Calendar.MINUTE, 1);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
stmt.setDate(1, new java.sql.Date(cal.getTimeInMillis()));
Also, you do not have to use nested CASEs. You can use several WHEN-THEN lines and the ELSE line is also optional eventhough I recomend it
CASE
WHEN [condition.1] THEN [expression.1]
WHEN [condition.2] THEN [expression.2]
...
WHEN [condition.n] THEN [expression.n]
ELSE [expression]
END
put this in your php page.
ini_set("error_reporting", E_ALL & ~E_DEPRECATED);
In httpd.conf file you need to remove #
#LoadModule rewrite_module modules/mod_rewrite.so
after removing # line will look like this:
LoadModule rewrite_module modules/mod_rewrite.so
And Apache restart

You can do this with a list comprehension:
T2 = [[int(column) for column in row] for row in T1]
The inner list comprehension ([int(column) for column in row]
) builds a list
of int
s from a sequence of int
-able objects, like decimal strings, in row
. The outer list comprehension ([... for row in T1])
) builds a list of the results of the inner list comprehension applied to each item in T1
.
The code snippet will fail if any of the rows contain objects that can't be converted by int
. You'll need a smarter function if you want to process rows containing non-decimal strings.
If you know the structure of the rows, you can replace the inner list comprehension with a call to a function of the row. Eg.
T2 = [parse_a_row_of_T1(row) for row in T1]
this may not be accurate but its close enough for me
long size = 0;
object o = new object();
using (Stream s = new MemoryStream()) {
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(s, o);
size = s.Length;
}
Since you are not interested in keeping any data, drop the entire database and create a new one.
While I agree that this should not be a comment, but a docstring as most (all?) answers suggest, I want to add numpydoc (a docstring style guide).
If you do it like this, you can (1) automatically generate documentation and (2) people recognize this and have an easier time to read your code.
// String to Utf8 ByteBuffer
function strToUTF8(str){
return Uint8Array.from(encodeURIComponent(str).replace(/%(..)/g,(m,v)=>{return String.fromCodePoint(parseInt(v,16))}), c=>c.codePointAt(0))
}
// Utf8 ByteArray to string
function UTF8toStr(ba){
return decodeURIComponent(ba.reduce((p,c)=>{return p+'%'+c.toString(16),''}))
}
On top of what Jimmy said, you can also make the select generic by using Convert.ChangeType
along with the necessary null checks:
public T GetColumnValue<T>(DataRow row, string columnName)
{
T value = default(T);
if (row.Table.Columns.Contains(columnName) && row[columnName] != null && !String.IsNullOrWhiteSpace(row[columnName].ToString()))
{
value = (T)Convert.ChangeType(row[columnName].ToString(), typeof(T));
}
return value;
}
Um, lots.
There are several parameters here. The specific VM, plus there are usually run-time parameters on the VM as well. That's somewhat driven by the operating system: what support does the underlying OS have for threads and what limitations does it put on them? If the VM actually uses OS-level threads at all, the good old red thread/green thread thing.
What "support" means is another question. If you write a Java program that is just something like
class DieLikeADog {
public static void main(String[] argv){
for(;;){
new Thread(new SomeRunaable).start();
}
}
}
(and don't complain about little syntax details, I'm on my first cup of coffee) then you should certainly expect to get hundreds or thousands of threads running. But creating a Thread is relatively expensive, and scheduler overhead can get intense; it's unclear that you could have those threads do anything useful.
Okay, couldn't resist. Here's my little test program, with a couple embellishments:
public class DieLikeADog {
private static Object s = new Object();
private static int count = 0;
public static void main(String[] argv){
for(;;){
new Thread(new Runnable(){
public void run(){
synchronized(s){
count += 1;
System.err.println("New thread #"+count);
}
for(;;){
try {
Thread.sleep(1000);
} catch (Exception e){
System.err.println(e);
}
}
}
}).start();
}
}
}

Use this Command
if(JButton.getModel().isArmed()){

}
Answer is short. But it worked for me. Use the variable name of your button instead of "JButton".
Based on my little knowledge of Oracle... a USER and a SCHEMA are somewhat similar. But there is also a major difference. A USER can be called a SCHEMA if the "USER" owns any object, otherwise ... it will only remain a "USER". Once the USER owns at least one object then by virtue of all of your definitions above.... the USER can now be called a SCHEMA.
You can run npx webpack

In medicine there are four genders: male, female, indeterminate, and unknown. You mightn't need all four but you certainly need 1, 2, and 4. It's not appropriate to have a default value for this datatype. Even less to treat it as a Boolean with 'is' and 'isn't' states.

With no path it serves the current folder.
By default it serves index.html

and you can serve https.
Actually there is no c3 in the sample code in the original question. So the if would be more properly
if (c1 && c2) {
//sequence 1
} else if (!c1 && !c2) {
// sequence 3
}
You could search for:
<li><a href="#">[^\n]+
And replace with:
$0</a>
Where $0
is the whole match. The exact semantics will depend on the language are you using though.

if(typeof next== 'object' && next!= null){
collection[index++]= item +
':{ '+ lookdeep(next).join(', ')+'}';
}
else collection[index++]= [item+':'+String(next)];

}
return collection;
}

};
var lookdeepSample= 'O={'+ lookdeep(O).join(',\n')+'}';
/* returned value: (String)

For Linux, "ps aux | grep kafka" see if kafka properties are shown in the results. E.g. /path/to/kafka/server.properties
On Ubuntu, placed your id_rsa

Now everything should jive with the SCM Sync Plugin.
Usually, git creates a hidden directory in project's root directory (.git/)
When you're working on a CMS, its possible you install modules/plugins carrying .git/ directory with git's metadata for the specific module/plugin
Quickest solution is to find all .git directories and keep only your root git metadata directory. If you do so, git will not consider those modules as project submodules.
This is what I prefer to use:
<script type="text/javascript">
$(document).ready(function () {
$("#fieldID").focus();
});
</script>
Simply restarting Visual Studio worked for me.
It is also worth noting that this:

If you don't mind messing with z-index, but you want to avoid adding extra div for overlay, you can use the following approach
/* make sure ::before is positioned relative to .foo */
.foo { position: relative; }
/* overlay */
.foo::before {
content: '';
display: block;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: rgba(0,0,0,0.5);
z-index: 0;
}
/* make sure all elements inside .foo placed above overlay element */
.foo > * { z-index: 1; }

I have solved the issue by using UINavigationController when presenting. In MainVC, when presenting VC1
let vc1 = VC1()
let navigationVC = UINavigationController(rootViewController: vc1)
self.present(navigationVC, animated: true, completion: nil)
In VC1, when I would like to show VC2 and dismiss VC1 in same time (just one animation), I can have a push animation by
let vc2 = VC2()
self.navigationController?.setViewControllers([vc2], animated: true)
And in VC2, when close the view controller, as usual we can use:
self.dismiss(animated: true, completion: nil)
You can accomplish this (if I understand what you are trying to do) using dynamic SQL.
The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.
So you can use something like this approach:
SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue
+ ' AS fld1 FROM tbl' + @KeyValue
EXEC (@stmt)
First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:
'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'
At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE
(or EXEC
for short).
The old-school sp_executesql
procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.
FOLLOWUP
EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.
Consider what would happen if @KeyValue
contained the string:
'1 AS foo; DROP TABLE students; -- '
The string we would produce as a SQL statement would be:
'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'
When we EXECUTE that string as a SQL statement:
INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...
And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)
One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'
. If an illegal character is found, then reject the value, and exit without executing any SQL.
It's because the name
column on the bar
table does not have the UNIQUE constraint.
So imagine you have 2 rows on the bar
table that contain the name 'ams'
and you insert a row on baz
with 'ams'
on bar_fk
, which row on bar
would it be referring since there are two rows matching?
You can create with javascript some css-rules
, which you can later use in your styles: http://jsfiddle.net/ARTsinn/vKbda/
var addRule = (function (sheet) {
if(!sheet) return;
return function (selector, styles) {
if (sheet.insertRule) return sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
if (sheet.addRule) return sheet.addRule(selector, styles);
}
}(document.styleSheets[document.styleSheets.length - 1]));
var i = 101;
while (i--) {
addRule("[data-width='" + i + "%']", "width:" + i + "%");
}
This creates 100 pseudo-selectors like this:
[data-width='1%'] { width: 1%; }
[data-width='2%'] { width: 2%; }
[data-width='3%'] { width: 3%; }
...
[data-width='100%'] { width: 100%; }
Note: This is a bit offtopic, and not really what you (or someone) wants, but maybe helpful.
Another alternative is using SDKMAN! See https://wimdeblauwe.wordpress.com/2018/09/26/switching-between-jdk-8-and-11-using-sdkman/
First install SDKMAN: https://sdkman.io/install and then...
sdk install java 8.0.181-oracle
sdk install java 11.0.0-open
To switch:
sdk use java 8.0.181-oracle
sdk use java 11.0.0-open
To set a default:
sdk default java 8.0.181-oracle
sdk default java 11.0.0-open
Each Entry object represents key-value pair. Field next refers to other Entry object if a bucket has more than 1 Entry.
Sometimes it might happen that hashCodes for 2 different objects are the same. In this case 2 objects will be saved in one bucket and will be presented as LinkedList. The entry point is more recently added object. This object refers to other object with next field and so one. Last entry refers to null. When you create HashMap with default constructor
Array is gets created with size 16 and default 0.75 load balance.
If you're trying to stop someone from updating the checkbox so it appears disabled then just use JQuery
$('input[type=checkbox]').click(false);
You can then style the checkbox.
The include relationship allows one use case to include the steps of another use case.
For example, suppose you have an Amazon Account and you want to check on an order, well it is impossible to check on the order without first logging into your account. So the flow of events would like so...
The extend relationship is used to add an extra step to the flow of a use case, that is usually an optional step...
Imagine that we are still talking about your amazon account. Lets assume the base case is Order and the extension use case is Amazon Prime. The user can choose to just order the item regularly, or, the user has the option to select Amazon Prime which ensure his order will arrive faster at higher cost.
However, note that the user does not have to select Amazon Prime, this is just an option, they can choose to ignore this use case.
The usual code (below) does not work for me:
$('#myModal').on('shown.bs.modal', function () {
$('#myInput').focus()
})
I found the solution:
$('body').on('shown.bs.modal', '#myModal', function () {
$('input:visible:enabled:first', this).focus();
})
What you want to do is -
strtemp = ";".join(l)
The first line adds a ;
to the end of MySpace
so that while splitting, it does not give out MySpaceApple
This will join l into one string and then you can just-
l1 = strtemp.split(";")
This works because strtemp is a string which has .split()
String is an Object and can be null
null means that the String Object was not instantiated
"" is an actual value of the instantiated Object String like "aaa"
Here is a link that might clarify that point http://download.oracle.com/javase/tutorial/java/concepts/object.html
Noticing that user 42-'s perfect approach {
* "do while" = "repeat until not"
* The code equivalence:
do while (condition) # in other language
..statements..
endo
repeat{ # in R
..statements..
if(! condition){ break } # Negation is crucial here!
}
} did not receive enough attention from the others, I'll emphasize and bring forward his approach via a concrete example. If one does not negate the condition in do-while (via !
or by taking negation), then distorted situations (1. value persistence 2. infinite loop) exist depending on the course of the code.
In Gauss:
proc(0)=printvalues(y);
DO WHILE y < 5;
y+1;
y=y+1;
ENDO;
ENDP;
printvalues(0); @ run selected code via F4 to get the following @
1.0000000
2.0000000
3.0000000
4.0000000
5.0000000
In R:
printvalues <- function(y) {
repeat {
y=y+1;
print(y)
if (! (y < 5) ) {break} # Negation is crucial here!
}
}
printvalues(0)
# [1] 1
# [1] 2
# [1] 3
# [1] 4
# [1] 5
I still insist that without the negation of the condition in do-while, Salcedo's answer is wrong. One can check this via removing negation symbol in the above code.
With POD you can also write
Snapshot s = {};
You shouldn't use memset in C++, memset has the drawback that if there is a non-POD in the struct it will destroy it.
or like this:
struct init
{
template <typename T>
operator T * ()
{
return new T();
}
};
Snapshot* s = init();
use min-height
instead of height
Use int.TryParse instead to get rid of the try-catch block:
if (!int.TryParse(Request.QueryString["id"], out id))
{
// error case
}
UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
animatedImageView.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"image1.gif"],
[UIImage imageNamed:@"image2.gif"],
[UIImage imageNamed:@"image3.gif"],
[UIImage imageNamed:@"image4.gif"], nil];
animatedImageView.animationDuration = 1.0f;
animatedImageView.animationRepeatCount = 0;
[animatedImageView startAnimating];
[self.view addSubview: animatedImageView];
You can load more than one gif images.
You can split your gif using the following ImageMagick command:
convert +adjoin loading.gif out%d.gif
How about this:
public T[] CloneCopy(T[] array, int startIndex, int endIndex) where T : ICloneable
{
T[] retArray = new T[endIndex - startIndex];
for (int i = startIndex; i < endIndex; i++)
{
array[i - startIndex] = array[i].Clone();
}
return retArray;
}
You then need to implement the ICloneable interface on all of the classes you need to use this on but that should do it.
Sometimes it would be nice to have operator overloading, friend classes and multiple inheritance.
However I still think it was a good decision. If Java would have had operator overloading then we could never be sure of operator meanings without looking through source code. At present that's not necessary. And I think your example of using methods instead of operator overloading is also quite readable. If you want to make things more clear you could always add a comment above hairy statements.

If you make document dependent on DOCTYPE
(e.g. use named entities) then it will stop being standalone, thus standalone="yes"
won't be allowed in XML declaration.
However standalone XML can be used anywhere, while non-standalone is problematic for XML parsers that don't load externals.
I don't see how this declaration could be a problem, other than for interoperability with software that doesn't support XML, but some horrible regex soup.
I follow all recommendations and all requirements. I install my self signed root CA on my iPhone. I make it trusted. I put certificate signed with this root CA on my local development server and I still get certificated error on safari iOS. Working on all other platforms.
HTML :
<div id="myDiv">
<form id="myForm">

</div>
jQuery :
var chbx='<input type="checkbox" id="Mumbai" name="Mumbai" value="Mumbai" />Mumbai<br /> <input type="checkbox" id=" Delhi" name=" Delhi" value=" Delhi" /> Delhi<br/><input type="checkbox" id=" Bangalore" name=" Bangalore" value=" Bangalore"/>Bangalore<br />';
$("#myDiv form#myForm").html(chbx);
//to insert dynamically created form
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");
Note: The following only works for the next line of code, and only due to a coincidence.
With Lodash,
require('lodash');
_.isArray([]); // true
No var _ = require('lodash')

A somewhat different approach using ggplot2:
dat <- read.table(text = "A B C D E F G
1 480 780 431 295 670 360 190
2 720 350 377 255 340 615 345
3 460 480 179 560 60 735 1260
4 220 240 876 789 820 100 75", header = TRUE)
library(reshape2)
dat$row <- seq_len(nrow(dat))
dat2 <- melt(dat, id.vars = "row")
library(ggplot2)
ggplot(dat2, aes(x = variable, y = value, fill = row)) +
geom_bar(stat = "identity") +
xlab("\nType") +
ylab("Time\n") +
guides(fill = FALSE) +
theme_bw()
this gives:
When you want to include a legend, delete the guides(fill = FALSE)
line.
Try below block of code, its working for me.
char *p = "0x820";
uint16_t intVal;
sscanf(p, "%x", &intVal);
printf("value x: %x - %d", intVal, intVal);
Output is:
value x: 820 - 2080
You can check Observable represented by Rxjs, lets you return more than one value.

Works on Win7.
<sup>
and <sub>
tags work and are your only good solution for arbitrary text. Other solutions include:
Unicode
If the superscript (or subscript) you need is of a mathematical nature, Unicode may well have you covered.
I've compiled a list of all the Unicode super and subscript characters I could identify in this gist. Some of the more common/useful ones are:
°
SUPERSCRIPT ZERO (U+2070)¹
SUPERSCRIPT ONE (U+00B9)²
SUPERSCRIPT TWO (U+00B2)³
SUPERSCRIPT THREE (U+00B3)n
SUPERSCRIPT LATIN SMALL LETTER N (U+207F)People also often reach for <sup>
and <sub>
tags in an attempt to render specific symbols like these:
™
TRADE MARK SIGN (U+2122)®
REGISTERED SIGN (U+00AE)?
SERVICE MARK (U+2120)Assuming your editor supports Unicode, you can copy and paste the characters above directly into your document.
Alternatively, you could use the hex values above in an HTML character escape. Eg, ²
instead of ²
. This works with GitHub (and should work anywhere else your Markdown is rendered to HTML) but is less readable when presented as raw text/Markdown.
Images
If your requirements are especially unusual, you can always just inline an image. The GitHub supported syntax is:
![Alt text goes here, if you'd like](path/to/image.png)
You can use a full path (eg. starting with https://
or http://
) but it's often easier to use a relative path, which will load the image from the repo, relative to the Markdown document.
If you happen to know LaTeX (or want to learn it) you could do just about any text manipulation imaginable and render it to an image. Sites like Quicklatex make this quite easy.
Why not graph the percentage complete. If you include the last date as a 100% complete value you can force the chart to show the linear trend as well as the actual data. This should give you a reasonable idea of whether you are above or below the line.
I would include a screenshot but not enough rep. Here is a link to one I prepared earlier. Burn Down Chart.
You can use literal quoting:
stmt := q'[insert into MY_TBL (Col) values('ER0002')]';
Documentation for literals can be found here.
Alternatively, you can use two quotes to denote a single quote:
stmt := 'insert into MY_TBL (Col) values(''ER0002'')';
The literal quoting mechanism with the Q syntax is more flexible and readable, IMO.
If you don't want to use SMO, for example because you need to be cross-platform, you can also use the ScriptSplitter class from SubText.
Here's the implementation in C# & VB.NET
Usage:
string strSQL = @"
SELECT * FROM INFORMATION_SCHEMA.columns
GO
SELECT * FROM INFORMATION_SCHEMA.views
";
foreach(string Script in new Subtext.Scripting.ScriptSplitter(strSQL ))
{
Console.WriteLine(Script);
}
If you have problems with multiline c-style comments, remove the comments with regex:
static string RemoveCstyleComments(string strInput)
{
string strPattern = @"/[*][\w\d\s]+[*]/";
//strPattern = @"/\*.*?\*/"; // Doesn't work
//strPattern = "/\\*.*?\\*/"; // Doesn't work
//strPattern = @"/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/ "; // Doesn't work
//strPattern = @"/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/ "; // Doesn't work
// http://stackoverflow.com/questions/462843/improving-fixing-a-regex-for-c-style-block-comments
strPattern = @"/\*(?>(?:(?>[^*]+)|\*(?!/))*)\*/"; // Works !
string strOutput = System.Text.RegularExpressions.Regex.Replace(strInput, strPattern, string.Empty, System.Text.RegularExpressions.RegexOptions.Multiline);
Console.WriteLine(strOutput);
return strOutput;
} // End Function RemoveCstyleComments

Search for LISTEN directive in the apache config files (httpd.conf, apache2.conf, listen.conf,...) and if you see localhost, or 127.0.0.1, then you need to overwrite with your public ip.
Here is the solution for your query.
a=["first","middle","last"] # A sample list
print(a[0]) #prints the first item in the list because the index of the list always starts from 0.
print(a[-1]) #prints the last item in the list.
print(a[-2]) #prints the last second item in the list.
Output:
>>> first
>>> last
>>> middle
Just do
NSString* newString=[NSString stringWithFormat:@"first part of string (%@) third part of string", @"foo"];
This gives you
@"first part of string (foo) third part of string"
The only way that works for me (extracted from here):
chmod a+x name_of_file.bin
Then run it by writing
./name_of_file.bin
If you get a permission error you might have to launch your application with root privileges:
sudo ./name_of_file.bin
As others said, you may run your external program without xterm. However, if you want to run it in a terminal window, e.g. to let the user interact with it, xterm allows you to specify the program to run as parameter.
xterm -e any command
In Java code this becomes:
String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Runtime.getRuntime().exec(command);
Or, using ProcessBuilder:
String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Process proc = new ProcessBuilder(command).start();
Note: pandas.stats
has been removed with 0.20.0
It's possible to do this with pandas.stats.ols
:
>>> from pandas.stats.api import ols
>>> df = pd.DataFrame({"A": [10,20,30,40,50], "B": [20, 30, 10, 40, 50], "C": [32, 234, 23, 23, 42523]})
>>> res = ols(y=df['A'], x=df[['B','C']])
>>> res

It's a syntactically valid request, but not a satisfiable request. If you look further in that section you see:
If a syntactically valid byte-range-set includes at least one byte- range-spec whose first-byte-pos is less than the current length of the entity-body, or at least one suffix-byte-range-spec with a non- zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable. If the byte-range-set is unsatisfiable, the server SHOULD return a response with a status of 416 (Requested range not satisfiable). Otherwise, the server SHOULD return a response with a status of 206 (Partial Content) containing the satisfiable ranges of the entity-body.
So I think in your example, the server should return a 416 since it's not a valid byte range for that file.
Hi a small correction in the above script.. above script skipping the first character when displaying the output.
function stripSlashes(x)
{
var y = "";
for(i = 0; i < x.length; i++)
{
if(x.charAt(i) == "/")
{
y += "";
}
else
{
y+= x.charAt(i);
}
}
return y;
}
SQL Server:
select * from table
except
select top N * from table
Oracle up to 11.2:
select * from table
minus
select * from table where rownum <= N
with TableWithNum as (
select t.*, rownum as Num
from Table t
)
select * from TableWithNum where Num > N
Oracle 12.1 and later (following standard ANSI SQL)
select *
from table
order by some_column
offset x rows
fetch first y rows only
They may meet your needs more or less.
There is no direct way to do what you want by SQL. However, it is not a design flaw, in my opinion.
SQL is not supposed to be used like this.
In relational databases, a table represents a relation, which is a set by definition. A set contains unordered elements.
Also, don't rely on the physical order of the records. The row order is not guaranteed by the RDBMS.
If the ordering of the records is important, you'd better add a column such as `Num' to the table, and use the following query. This is more natural.
select *
from Table
where Num > N
order by Num
First Create Procedure as Below:
CREATE DEFINER=`root`@`%` PROCEDURE `sp_split`(str nvarchar(6500), dilimiter varchar(15), tmp_name varchar(50))
BEGIN
declare end_index int;
declare part nvarchar(6500);
declare remain_len int;
set end_index = INSTR(str, dilimiter);
while(end_index != 0) do
/* Split a part */
set part = SUBSTRING(str, 1, end_index - 1);
/* insert record to temp table */
call `sp_split_insert`(tmp_name, part);
set remain_len = length(str) - end_index;
set str = substring(str, end_index + 1, remain_len);
set end_index = INSTR(str, dilimiter);
end while;
if(length(str) > 0) then
/* insert record to temp table */
call `sp_split_insert`(tmp_name, str);
end if;
END
After that create procedure as below:
CREATE DEFINER=`root`@`%` PROCEDURE `sp_split_insert`(tb_name varchar(255), tb_value nvarchar(6500))
BEGIN
SET @sql = CONCAT('Insert Into ', tb_name,'(item) Values(?)');
PREPARE s1 from @sql;
SET @paramA = tb_value;
EXECUTE s1 USING @paramA;
END
How call test
CREATE DEFINER=`root`@`%` PROCEDURE `test_split`(test_text nvarchar(255))
BEGIN
create temporary table if not exists tb_search
(
item nvarchar(6500)
);
call sp_split(test_split, ',', 'tb_search');
select * from tb_search where length(trim(item)) > 0;
drop table tb_search;
END
call `test_split`('Apple,Banana,Mengo');
Execute dump query in terminal then it will work
mysql -u root -p <Database_Name> > <path of the input file>
I too faced similar problem and problem was basically that I had opened multiple running terminals in powershell. So make sure you Ctrl+c all others.
I solved my problem completely different to any of the solutions in here:
Each of my tests made a call to a function which in turn called itself meaning it'd not terminate:
public GoogleIntent CreateIntent(BotPath botpath)
{
return CreateIntent(botpath);
}
I do this with a one liner:
val bitmap = MediaStore.Images.Media.getBitmap(contentResolver, uri)
Which in the onActivityResult looks like:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (resultCode == Activity.RESULT_OK && requestCode == REQUEST_CODE_IMAGE_PICKER ) {
data?.data?.let { imgUri: Uri ->
val bitmap = MediaStore.Images.Media.getBitmap(contentResolver, imgUri)
}
}
}
If there are spaces in the phone2 field from inadvertant data entry, you can ignore those records with the IFNULL and TRIM functions:
SELECT phone, phone2
FROM jewishyellow.users
WHERE phone LIKE '813%'
AND TRIM(IFNULL(phone2,'')) <> '';
I hope this will help you:
final TextView t1=new TextView(this);
t1.setText("Hello Android");
final SeekBar sk=(SeekBar) findViewById(R.id.seekBar1);
sk.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {
// TODO Auto-generated method stub
t1.setTextSize(progress);
Toast.makeText(getApplicationContext(), String.valueOf(progress),Toast.LENGTH_LONG).show();
}
});
Have a look at Managing Hierarchical Data in MySQL. It discusses two approaches for storing and managing hierarchical (tree-like) data in a relational database.
The first approach is the adjacency list model, which is what you essentially describe: having a foreign key that refers to the table itself. While this approach is simple, it can be very inefficient for certain queries, like building the whole tree.
The second approach discussed in the article is the nested set model. This approach is far more efficient and flexible. Refer to the article for detailed explanation and example queries.
A developer recently added subtitle support to VideoView.
When the MediaPlayer
starts playing a music (or other source), it checks if there is a SubtitleController and shows this message if it's not set.
It doesn't seem to care about if the source you want to play is a music or video. Not sure why he did that.
Short answer: Don't care about this "Exception".
Edit :
Still present in Lollipop,
If MediaPlayer
is only used to play audio files and you really want to remove these errors in the logcat, the code bellow set an empty SubtitleController
to the MediaPlayer
.
It should not be used in production environment and may have some side effects.
static MediaPlayer getMediaPlayer(Context context){
MediaPlayer mediaplayer = new MediaPlayer();
if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.KITKAT) {
return mediaplayer;
}
try {
Class<?> cMediaTimeProvider = Class.forName( "android.media.MediaTimeProvider" );
Class<?> cSubtitleController = Class.forName( "android.media.SubtitleController" );
Class<?> iSubtitleControllerAnchor = Class.forName( "android.media.SubtitleController$Anchor" );
Class<?> iSubtitleControllerListener = Class.forName( "android.media.SubtitleController$Listener" );
Constructor constructor = cSubtitleController.getConstructor(new Class[]{Context.class, cMediaTimeProvider, iSubtitleControllerListener});
Object subtitleInstance = constructor.newInstance(context, null, null);
Field f = cSubtitleController.getDeclaredField("mHandler");
f.setAccessible(true);
try {
f.set(subtitleInstance, new Handler());
}
catch (IllegalAccessException e) {return mediaplayer;}
finally {
f.setAccessible(false);
}
Method setsubtitleanchor = mediaplayer.getClass().getMethod("setSubtitleAnchor", cSubtitleController, iSubtitleControllerAnchor);
setsubtitleanchor.invoke(mediaplayer, subtitleInstance, null);
//Log.e("", "subtitle is setted :p");
} catch (Exception e) {}
return mediaplayer;
}
This code is trying to do the following from the hidden API
SubtitleController sc = new SubtitleController(context, null, null);
sc.mHandler = new Handler();
mediaplayer.setSubtitleAnchor(sc, null)
