Another possible cause of similar issue could be wrong processorArchitecture
in the cx_freeze manifest, trying to load x86 common controls dll in x64 process - should be fixed by this patch:
Try this:
keys=pygame.key.get_pressed()
if keys[K_LEFT]:
if count == 10:
location-=1
count=0
else:
count +=1
if location==-1:
location=0
if keys[K_RIGHT]:
if count == 10:
location+=1
count=0
else:
count +=1
if location==5:
location=4
This will mean you only move 1/10 of the time. If it still moves to fast you could try increasing the value you set "count" too.
If you scale 1600x900
to 1280x720
you have
scale_x = 1280.0/1600
scale_y = 720.0/900
Then you can use it to find button size, and button position
button_width = 300 * scale_x
button_height = 300 * scale_y
button_x = 1440 * scale_x
button_y = 860 * scale_y
If you scale 1280x720
to 1600x900
you have
scale_x = 1600.0/1280
scale_y = 900.0/720
and rest is the same.
I add .0
to value to make float
- otherwise scale_x
, scale_y
will be rounded to integer
- in this example to 0

I am a quite newbie to python and I was having same issue. (windows x64 os) I have solved, doing below steps
Yes. It is possible to draw text in pygame:
# initialize font; must be called after 'pygame.init()' to avoid 'Font not Initialized' error
myfont = pygame.font.SysFont("monospace", 15)
# render text
label = myfont.render("Some text!", 1, (255,255,0))
screen.blit(label, (100, 100))
When displaying I sometimes make a new file called Funk. This will have the font, size etc. This is the code for the class:
import pygame
def text_to_screen(screen, text, x, y, size = 50,
color = (200, 000, 000), font_type = 'data/fonts/orecrusherexpand.ttf'):
try:
text = str(text)
font = pygame.font.Font(font_type, size)
text = font.render(text, True, color)
screen.blit(text, (x, y))
except Exception, e:
print 'Font Error, saw it coming'
raise e
Then when that has been imported when I want to display text taht updates E.G score I do:
Funk.text_to_screen(screen, 'Text {0}'.format(score), xpos, ypos)
If it is just normal text that isn't being updated:
Funk.text_to_screen(screen, 'Text', xpos, ypos)
You may notice {0} on the first example. That is because when .format(whatever) is used that is what will be updated. If you have something like Score then target score you'd do {0} for score then {1} for target score then .format(score, targetscore)
The pygame documentation for mouse events is here. You can either use the pygame.mouse.get_pressed
method in collaboration with the pygame.mouse.get_pos
(if needed). But please use the mouse click event via a main event loop. The reason why the event loop is better is due to "short clicks". You may not notice these on normal machines, but computers that use tap-clicks on trackpads have excessively small click periods. Using the mouse events will prevent this.
EDIT:
To perform pixel perfect collisions use pygame.sprite.collide_rect()
found on their docs for sprites.
here's how:
import pygame
screen=pygame.display.set_mode([640, 480])
screen.fill([255, 255, 255])
red=255
blue=0
green=0
left=50
top=50
width=90
height=90
filled=0
pygame.draw.rect(screen, [red, blue, green], [left, top, width, height], filled)
pygame.display.flip()
running=True
while running:
for event in pygame.event.get():
if event.type==pygame.QUIT:
running=False
pygame.quit()
You can use send_keys
to simulate an END
(or PAGE_DOWN
) key press (which normally scroll the page):
from selenium.webdriver.common.keys import Keys
html = driver.find_element_by_tag_name('html')
html.send_keys(Keys.END)

The reply by Phil Sacre was correct however the session shouldn't be used just for the hell of it. You should only use this for values which really need to live for the lifetime of the session, such as a user login. It's common to see people overuse the session and run into more issues, especially when dealing with a collection or when users return to a page they previously visited only to find they have values still remaining from a previous visit. A smart program minimizes the scope of variables as much as possible, a bad one uses session too much.
Try to use a for each
for ( Direction direction : Direction.values()){
System.out.println(direction.toString());
}
You simply forgot to supply an argument to -i

Of course that means you don't want your files to be backed up; otherwise supply your extension of choice, like -i .bak

Your code looks great, the only thing i see is that you did not include the collapsed class in your button selector. http://www.bootply.com/cpHugxg2f8 Note: Requires JavaScript plugin If JavaScript is disabled and the viewport is narrow enough that the navbar collapses, it will be impossible to expand the navbar and view the content within the .navbar-collapse.

Use this:
if(typeof(String.prototype.trim) === "undefined")
{
String.prototype.trim = function()
{
return String(this).replace(/^\s+|\s+$/g, '');
};
}
The trim function will now be available as a first-class function on your strings. For example:
" dog".trim() === "dog" //true
EDIT: Took J-P's suggestion to combine the regex patterns into one. Also added the global modifier per Christoph's suggestion.
Took Matthew Crumley's idea about sniffing on the trim function prior to recreating it. This is done in case the version of JavaScript used on the client is more recent and therefore has its own, native trim function.

As stated in the question:
To align flex items along the main axis there is one property:
justify-content
To align flex items along the cross axis there are three properties:
align-content
,align-items
andalign-self
.
The question then asks:
Why are there no
justify-items
andjustify-self
properties?
One answer may be: Because they're not necessary.
The flexbox specification provides two methods for aligning flex items along the main axis:
justify-content
keyword property, andauto
marginsjustify-content
The justify-content
property aligns flex items along the main axis of the flex container.
It is applied to the flex container but only affects flex items.
There are five alignment options:
flex-start
~ Flex items are packed toward the start of the line.
flex-end
~ Flex items are packed toward the end of the line.
center
~ Flex items are packed toward the center of the line.
space-between
~ Flex items are evenly spaced, with the first item aligned to one edge of the container and the last item aligned to the opposite edge. The edges used by the first and last items depends on flex-direction
and writing mode (ltr
or rtl
).
space-around
~ Same as space-between
except with half-size spaces on both ends.
With auto
margins, flex items can be centered, spaced away or packed into sub-groups.
Unlike justify-content
, which is applied to the flex container, auto
margins go on flex items.
They work by consuming all free space in the specified direction.
Scenario from the question:
making a group of flex items align-right (
justify-content: flex-end
) but have the first item align left (justify-self: flex-start
)Consider a header section with a group of nav items and a logo. With
justify-self
the logo could be aligned left while the nav items stay far right, and the whole thing adjusts smoothly ("flexes") to different screen sizes.
Other useful scenarios:
Scenario from the question:
- placing a flex item in a corner
.box { align-self: flex-end; justify-self: flex-end; }
margin: auto
is an alternative to justify-content: center
and align-items: center
.
Instead of this code on the flex container:
.container {
justify-content: center;
align-items: center;
}
You can use this on the flex item:
.box56 {
margin: auto;
}
This alternative is useful when centering a flex item that overflows the container.
A flex container aligns flex items by distributing free space.
Hence, in order to create equal balance, so that a middle item can be centered in the container with a single item alongside, a counterbalance must be introduced.
In the examples below, invisible third flex items (boxes 61 & 68) are introduced to balance out the "real" items (box 63 & 66).
Of course, this method is nothing great in terms of semantics.
Alternatively, you can use a pseudo-element instead of an actual DOM element. Or you can use absolute positioning. All three methods are covered here: Center and bottom-align flex items
NOTE: The examples above will only work – in terms of true centering – when the outermost items are equal height/width. When flex items are different lengths, see next example.
Scenario from the question:
in a row of three flex items, affix the middle item to the center of the container (
justify-content: center
) and align the adjacent items to the container edges (justify-self: flex-start
andjustify-self: flex-end
).Note that values
space-around
andspace-between
onjustify-content
property will not keep the middle item centered in relation to the container if the adjacent items have different widths (see demo).
As noted, unless all flex items are of equal width or height (depending on flex-direction
), the middle item cannot be truly centered. This problem makes a strong case for a justify-self
property (designed to handle the task, of course).

</div>_x000D_
_x000D_
<p>The middle box will be truly centered only if adjacent boxes are equal width.</p>
_x000D_
Here are two methods for solving this problem:
Solution #1: Absolute Positioning
The flexbox spec allows for absolute positioning of flex items. This allows for the middle item to be perfectly centered regardless of the size of its siblings.
Just keep in mind that, like all absolutely positioned elements, the items are removed from the document flow. This means they don't take up space in the container and can overlap their siblings.
In the examples below, the middle item is centered with absolute positioning and the outer items remain in-flow. But the same layout can be achieved in reverse fashion: Center the middle item with justify-content: center
and absolutely position the outer items.
Solution #2: Nested Flex Containers (no absolute positioning)
.container {_x000D_
display: flex;_x000D_
}_x000D_
.box {_x000D_
flex: 1;_x000D_
display: flex;_x000D_
justify-content: center;_x000D_
}_x000D_
.box71 > span { margin-right: auto; }_x000D_
.box73 > span { margin-left: auto; }_x000D_
_x000D_
/* non-essential */_x000D_
.box {_x000D_
align-items: center;_x000D_
border: 1px solid #ccc;_x000D_
background-color: lightgreen;_x000D_
height: 40px;_x000D_
}
_x000D_
<div class="container">_x000D_
<div class="box box71"><span>71 short</span></div>_x000D_
<div class="box box72"><span>72 centered</span></div>_x000D_
<div class="box box73"><span>73 loooooooooooooooong</span></div>_x000D_
</div>
_x000D_
Here's how it works:
.container
) is a flex container..box
) is now a flex item..box
item is given flex: 1
in order to distribute container space equally.justify-content: center
.span
element is a centered flex item.auto
margins to shift the outer span
s left and right.You could also forgo justify-content
and use auto
margins exclusively.
But justify-content
can work here because auto
margins always have priority. From the spec:
8.1. Aligning with
auto
marginsPrior to alignment via
justify-content
andalign-self
, any positive free space is distributed to auto margins in that dimension.
justify-content: space-same (concept)
Going back to justify-content
for a minute, here's an idea for one more option.
space-same
~ A hybrid of space-between
and space-around
. Flex items are evenly spaced (like space-between
), except instead of half-size spaces on both ends (like space-around
), there are full-size spaces on both ends.This layout can be achieved with ::before
and ::after
pseudo-elements on the flex container.
(credit: @oriol for the code, and @crl for the label)
UPDATE: Browsers have begun implementing space-evenly
, which accomplishes the above. See this post for details: Equal space between flex items

Clearly HttpContext.Current
is not null
only if you access it in a thread that handles incoming requests. That's why it works "when i use this code in another class of a page".
It won't work in the scheduling related class because relevant code is not executed on a valid thread, but a background thread, which has no HTTP context associated with.
Overall, don't use Application["Setting"]
to store global stuffs, as they are not global as you discovered.
If you need to pass certain information down to business logic layer, pass as arguments to the related methods. Don't let your business logic layer access things like HttpContext
or Application["Settings"]
, as that violates the principles of isolation and decoupling.
Update:
Due to the introduction of async/await
it is more often that such issues happen, so you might consider the following tip,
In general, you should only call HttpContext.Current
in only a few scenarios (within an HTTP module for example). In all other cases, you should use
Page.Context
https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.page.context?view=netframework-4.7.2 Controller.HttpContext
https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.controller.httpcontext?view=aspnet-mvc-5.2instead of HttpContext.Current
.
For this the System.Timers.Timer
works best
// Create a timer
myTimer = new System.Timers.Timer();
// Tell the timer what to do when it elapses
myTimer.Elapsed += new ElapsedEventHandler(myEvent);
// Set it to go off every five seconds
myTimer.Interval = 5000;
// And start it
myTimer.Enabled = true;
// Implement a call with the right signature for events going off
private void myEvent(object source, ElapsedEventArgs e) { }
See Timer Class (.NET 4.6 and 4.5) for details

I had to find another solution because none of the provided solutions actually met my requirements, for the following reasons:
Query strings: You may not want to use query strings because the URLs could be shared by your users, and sometimes the query parameters do not make sense for a different user. For example, an error such as ?error=sessionExpired
should never be displayed to another user by accident.
req.session: You may not want to use req.session
because you need the express-session dependency for this, which includes setting up a session store (such as MongoDB), which you may not need at all, or maybe you are already using a custom session store solution.
next(): You may not want to use next()
or next("router")
because this essentially just renders your new page under the original URL, it's not really a redirect to the new URL, more like a forward/rewrite, which may not be acceptable.
So this is my fourth solution that doesn't suffer from any of the previous issues. Basically it involves using a temporary cookie, for which you will have to first install cookie-parser. Obviously this means it will only work where cookies are enabled, and with a limited amount of data.
Implementation example:
var cookieParser = require("cookie-parser");
app.use(cookieParser());
app.get("/", function(req, res) {
var context = req.cookies["context"];
res.clearCookie("context", { httpOnly: true });
res.render("home.jade", context); // Here context is just a string, you will have to provide a valid context for your template engine
});
app.post("/category", function(req, res) {
res.cookie("context", "myContext", { httpOnly: true });
res.redirect("/");
}
You can parse a string into an integer with int.parse()
. For example:
var myInt = int.parse('12345');
assert(myInt is int);
print(myInt); // 12345
Note that int.parse()
accepts 0x
prefixed strings. Otherwise the input is treated as base-10.
You can parse a string into a double with double.parse()
. For example:
var myDouble = double.parse('123.45');
assert(myDouble is double);
print(myDouble); // 123.45
parse()
will throw FormatException if it cannot parse the input.

create two or more div's you want and give them a definite width like 100px for each then float it left or right
then warp these two div's in another div and give it the width of 200px. to this div apply margin auto. boom it works pretty well. check the above example.

Note that you can omit .slideContainer { overflow-x: scroll; }
(which browsers may or may not support when you read this), and you'll get a scrollbar on the window instead of on this container.
The key here is display: inline-block
. This has decent cross-browser support nowadays, but as usual, it's worth testing in all target browsers to be sure.
We can pass string value to main method as argument without using commandline argument concept in java through Netbean
package MainClass;
import java.util.Scanner;
public class CmdLineArgDemo {
static{
Scanner readData = new Scanner(System.in);
System.out.println("Enter any string :");
String str = readData.nextLine();
String [] str1 = str.split(" ");
// System.out.println(str1.length);
CmdLineArgDemo.main(str1);
}
public static void main(String [] args){
for(int i = 0 ; i<args.length;i++) {
System.out.print(args[i]+" ");
}
}
}
Enter any string :

$("#table tr").click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
var value=$(this).find('td:first').html();
alert(value);
});
$('.ok').on('click', function(e){
alert($("#table tr.selected td:first").html());
});
Demo:
In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as
save page as
filename : any_name.html
save as type : webpage complete.
Then you will get any_name.html
and any_name folder
.
Using the builtin Date.parse
function which accepts input in ISO8601 format and directly returns the desired integer return value:
var dates_as_int = dates.map(Date.parse);
Jar mismatch comes when you use library projects in your application and both projects are using same jar with different version so just check all library projects attached in your application. if some mismatch exist then remove it.
if above process is not working then just do remove project dependency from build path and again add library projects and build the application.
I'm surprised nobody mentioned the use of sibling combinators, which are supported by IE7 and later:
tr + tr /* CSS2, adjacent sibling */
tr ~ tr /* CSS3, general sibling */
They both function in exactly the same way (in the context of HTML tables anyway) as:
tr:not(:first-child)
In case you don't want to use API 21 as the target API, and thus you don' t want to use the Material Theme, you have to use an older revision belonging to API 19 >
compile "com.android.support:appcompat-v7:19.0.+"
This also helps solving your problem, it only depends on what you want to achieve.
to make your code look better when viewing source
$variable = 'foo';
echo "this is my php variable $variable \n";
echo "this is another php echo here $variable\n";
your code when view source will look like, with nice line returns thanks to \n
this is my php variable foo
this is another php echo here foo
If you want to remove the specific position element in a list, like the 2th, 3th and 7th. you can't use
del my_list[2]
del my_list[3]
del my_list[7]
Since after you delete the second element, the third element you delete actually is the fourth element in the original list. You can filter the 2th, 3th and 7th element in the original list and get a new list, like below:
new list = [j for i, j in enumerate(my_list) if i not in [2, 3, 7]]
As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.
Sample implementation using WatiN:
class FacebookUser
{
public string Name { get; set; }
public long Id { get; set; }
}
public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
var users = new List<FacebookUser>();
Settings.Instance.MakeNewIeInstanceVisible = false;
using (var browser = new IE("https://www.facebook.com"))
{
try
{
browser.TextField(Find.ByName("email")).Value = email;
browser.TextField(Find.ByName("pass")).Value = password;
browser.Form(Find.ById("login_form")).Submit();
browser.WaitForComplete();
}
catch (ElementNotFoundException)
{
// We're already logged in
}
browser.GoTo("https://www.facebook.com/friends");
var watch = new Stopwatch();
watch.Start();
Link previousLastLink = null;
while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
{
var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).LastOrDefault();
if (lastLink == null || previousLastLink == lastLink)
{
break;
}
var ieElement = lastLink.NativeElement as IEElement;
if (ieElement != null)
{
var htmlElement = ieElement.AsHtmlElement;
htmlElement.scrollIntoView();
browser.WaitForComplete();
}
previousLastLink = lastLink;
}
var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).ToList();
var idRegex = new Regex("id=(?<id>([0-9]+))");
foreach (var link in links)
{
string hovercard = link.GetAttributeValue("data-hovercard");
var match = idRegex.Match(hovercard);
long id = 0;
if (match.Success)
{
id = long.Parse(match.Groups["id"].Value);
}
users.Add(new FacebookUser
{
Name = link.Text,
Id = id
});
}
}
return users;
}
Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.
Here is my Approach based on DarKalimHero's Suggestion by selecting only on Explorer.exe processes
Function Get-RdpSessions
{
param(
[string]$computername
)
$processinfo = Get-WmiObject -Query "select * from win32_process where name='explorer.exe'" -ComputerName $computername
$processinfo | ForEach-Object { $_.GetOwner().User } | Sort-Object -Unique | ForEach-Object { New-Object psobject -Property @{Computer=$computername;LoggedOn=$_} } | Select-Object Computer,LoggedOn
}
This works:
$('body').append($("<script>alert('Hi!');<\/script>")[0]);
It seems like jQuery is doing something clever with scripts so you need to append the html element rather than jQuery object.
In EF Core, I use the following statements to rename tables and columns:
As for renaming tables:
protected override void Up(MigrationBuilder migrationBuilder)
{
migrationBuilder.RenameTable(name: "OldTableName", schema: "dbo", newName: "NewTableName", newSchema: "dbo");
}
protected override void Down(MigrationBuilder migrationBuilder)
{
migrationBuilder.RenameTable(name: "NewTableName", schema: "dbo", newName: "OldTableName", newSchema: "dbo");
}
As for renaming columns:
protected override void Up(MigrationBuilder migrationBuilder)
{
migrationBuilder.RenameColumn(name: "OldColumnName", table: "TableName", newName: "NewColumnName", schema: "dbo");
}
protected override void Down(MigrationBuilder migrationBuilder)
{
migrationBuilder.RenameColumn(name: "NewColumnName", table: "TableName", newName: "OldColumnName", schema: "dbo");
}
one more variant, but almost the same as Gumbos solution:
var isDebug = function(){
return window.location.href.search("[?&]debug=") != -1;
};
The "Pythonic" way to check if a string is empty is:
import random
variable = random.choice(l)
if variable:
# got a non-empty string
else:
# got an empty string
You didn't say what you needed this list for. If something used as a blacklist for password checks is enough cracklib might be good for you. It contains over 1.5M words.
JavaScript is a dynamic language. You could just add it to the object itself.
var marker = new google.maps.Marker(markerOptions);
marker.metadata = {type: "point", id: 1};
Also, because all v3 objects extend MVCObject()
. You can use:
marker.setValues({type: "point", id: 1});
// or
marker.set("type", "point");
marker.set("id", 1);
var val = marker.get("id");

The official mongo
image has merged a PR to include the functionality to databases and admin users at startup.
The database initialisation will run scripts in /docker-entrypoint-initdb.d/
when there is nothing populated in the /data/db
directory.
The mongo
container image provides the /docker-entrypoint-initdb.d/
path to deploy custom .js
or .sh
setup scripts that will be run once on database initialisation. .js
scripts will be run against test
by default or MONGO_INITDB_DATABASE
if defined in the environment.
COPY mysetup.sh /docker-entrypoint-initdb.d/
or
COPY mysetup.js /docker-entrypoint-initdb.d/
A simple initialisation mongo shell javascript file that demonstrates setting up the container
collection with data, logging and how to exit with an error (for result checking).
let error = true
let res = [
db.container.drop(),
db.container.createIndex({ myfield: 1 }, { unique: true }),
db.container.createIndex({ thatfield: 1 }),
db.container.createIndex({ thatfield: 1 }),
db.container.insert({ myfield: 'hello', thatfield: 'testing' }),
db.container.insert({ myfield: 'hello2', thatfield: 'testing' }),
db.container.insert({ myfield: 'hello3', thatfield: 'testing' }),
db.container.insert({ myfield: 'hello3', thatfield: 'testing' })
]
printjson(res)
if (error) {
print('Error, exiting')
quit(1)
}
The environment variables to control "root" user setup are
MONGO_INITDB_ROOT_USERNAME
MONGO_INITDB_ROOT_PASSWORD
Example
docker run -d \
-e MONGO_INITDB_ROOT_USERNAME=admin \
-e MONGO_INITDB_ROOT_PASSWORD=password \
mongod
or Dockerfile
FROM docker.io/mongo
ENV MONGO_INITDB_ROOT_USERNAME admin
ENV MONGO_INITDB_ROOT_PASSWORD password
You don't need to use --auth
on the command line as the docker entrypoint.sh
script adds this in when it detects the environment variables exist.
$sth = mysqli_query($conn, "SELECT ...");
$rows = array();
while($r = mysqli_fetch_assoc($sth)) {
$rows[] = $r;
}
print json_encode($rows);
The function json_encode
needs PHP >= 5.2 and the php-json package - as mentioned here
NOTE: mysql
is deprecated as of PHP 5.5.0, use mysqli
extension instead http://php.net/manual/en/migration55.deprecated.php.
First I recommand you can try use print and observe the action:
for i in range(0, 5, 1):
print i
the result:
0
1
2
3
4
You can understand the function principle.
In fact, range
scan range is from 0
to 5-1
.
It equals 0 <= i < 5
When you really understand for-loop in python, I think its time we get back to business. Let's focus your problem.
You want to use a DECREMENT for-loop in python. I suggest a for-loop tutorial for example.
for i in range(5, 0, -1):
print i
the result:
5
4
3
2
1
Thus it can be seen, it equals 5 >= i > 0
You want to implement your java code in python:
for (int index = last-1; index >= posn; index--)
It should code this:
for i in range(last-1, posn-1, -1)
This should solve your problem:
select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);
Give a look also as this SQL Fiddle for test.
1. SQL or Structured Query Language was developed by IBM for their product "System R".
Later ANSI made it as a Standard on which all Query Languages are based upon and have extended this to create their own DataBase Query Language suits. The first standard was SQL-86 and latest being SQL:2016
2. T-SQL or Transact-SQL was developed by Sybase and later co-owned by Microsoft SQL Server.
3. PL/SQL or Procedural Language/SQL was Oracle Database, known as "Relation Software" that time.
I've documented this in my blog post.
JMeter's built-in proxy may be used to record all HTTP request/response information.
Firefox "Live HTTP headers" plugin may be used to see what is happening on the browser side when sending/receiving request.
Firefox "Tamper data" plugin may be useful when you need to intercept and modify request.
In Python I have been using the Flask-CORS
library with great success. It makes dealing with CORS super easy and painless. I added some code from the library's documentation below.
Installing:
$ pip install -U flask-cors
Simple example that allows CORS for all domains on all routes:
from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app)
@app.route("/")
def helloWorld():
return "Hello, cross-origin-world!"
For more specific examples see the documentation. I have used the simple example above to get around the CORS issue in an ionic application I am building that has to access a separate flask server.
I used to use the PGP disk encryption product on a laptop (and ran NTFS compressed on top of that!). It didn't seem to have much effect if the amount of disk to be read was small; and most software sources aren't huge by disk standards.
You have lots of RAM and pretty fast processors. I spent most of my time thinking, typing or debugging.
I wouldn't worry very much about it.
JsonConvert
is from the namespace Newtonsoft.Json
, not System.ServiceModel.Web
Use NuGet
to download the package
"Project" -> "Manage NuGet packages" -> "Search for "newtonsoft json". -> click "install".
The key is the contentSize.
This is often missing and not indicated when adding a UIScrollView.
Select the UIScrollView and select the Identity Inspector.
Add a contentSize
keyPath as a size
to the scrollView in the Identity Inspector and setting it to (320, 1000).
Scroll away.
Something like this would work
/^\d{2}$/
div {_x000D_
display: table-cell;_x000D_
vertical-align: middle;_x000D_
height: 50px;_x000D_
border: 1px solid red;_x000D_
}
_x000D_
<div>_x000D_
<label for='name'>Name:</label>_x000D_
<input type='text' id='name' />_x000D_
</div>
_x000D_
The advantages of this method is that you can change the height of the div
, change the height of the text field and change the font size and everything will always stay in the middle.
<head>
<script>
function myFunction() {
var x;
var r = confirm("Do you want to clear data?");
if (r == true) {
x = "Your Data is Cleared";
window.location.href = "firstpage.php";
}
else {
x = "You pressed Cancel!";
}
document.getElementById("demo").innerHTML = x;
}
</script>
</head>
<body>
<button onclick="myFunction()">Retest</button>
<p id="demo"></p>
</body>
</html>
This will redirect to new php page.
If you are mocking the behavior (with something like doNothing()
) there should really be no need to call to verify*()
. That said, here's my stab at re-writing your test method:
@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
public void testProcessOrder() {
//Variables
InternalService is = new InternalService();
Order order = mock(Order.class);
//Mock Behavior
when(order.isSuccessful()).thenReturn(true);
mockStatic(Internalutils.class);
doNothing().when(InternalUtils.class); //This is the preferred way
//to mock static void methods.
InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
//Execute
is.processOrder(order);
//Verify
verifyStatic(InternalUtils.class); //Similar to how you mock static methods
//this is how you verify them.
InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
}
}
I grouped into four sections to better highlight what is going on:
I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.
This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.
Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.
This is when you call any method starting with verify
or assert
. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.
This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.
I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:
You can use cut with a delimiter like this:
with space delim:
cut -d " " -f1-100,1000-1005 infile.csv > outfile.csv
with tab delim:
cut -d$'\t' -f1-100,1000-1005 infile.csv > outfile.csv
I gave you the version of cut in which you can extract a list of intervals...
Hope it helps!
easy one
("^ (?=.* [0-9]) (?=.* [a-z]) (?=.* [A-Z]) (?=.* [\\W_])[\\S]{8,10}$")
(?= anything ) ->means positive looks forward in all input string and make sure for this condition is written .sample(?=.*[0-9])-> means ensure one digit number is written in the all string.if not written return false .
(?! anything ) ->(vise versa) means negative looks forward if condition is written return false.
close meaning ^(condition)(condition)(condition)(condition)[\S]{8,10}$
From this page:
Make oldconfig takes the .config and runs it through the rules of the Kconfig files and produces a .config which is consistant with the Kconfig rules. If there are CONFIG values which are missing, the make oldconfig will ask for them.
If the .config is already consistant with the rules found in Kconfig, then make oldconfig is essentially a no-op.
If you were to run make oldconfig, and then run make oldconfig a second time, the second time won't cause any additional changes to be made.
depending on your tastes, an alternative to nico's answer:
d<-lapply(mylist, write, file=" ... ", append=T);
It works if id value and name value are different:
<input type="password" class="form-control"name="password" id="mainpassword">
password: { required: true, } ,
cpassword: {required: true, equalTo: '#mainpassword' },
# /home/{user}/.gemrc

first install moment via npm
npm install moment --save
Then import moment in the component that you want to use it
import * as moment from 'moment';
lastly configure moment in systemjs.config.js "map" and "packages"
// map tells the System loader where to look for things
var map = {
....
'moment': 'node_modules/moment'
};
// packages tells the System loader how to load when no filename and/or no extension
var packages = {
...
'moment': { main:'moment', defaultExtension: 'js'}
};

You can just copy the job and delete the old one. If it doesn't matter that you lost the old build logs.
The answer is right in the MYSQL manual itself.
"DELETE FROM `table_name` WHERE `time_col` < ADDDATE(NOW(), INTERVAL -1 HOUR)"
$('html, body').animate({scrollTop:1200},'50');
You can do this!
function setValToAssessment(id)
{
$.getJSON("<?= URL.$param->module."/".$param->controller?>/setvalue",{id: id}, function(response)
{
var form = $('<form></form>').attr("id",'hiddenForm' ).attr("name", 'hiddenForm');
$.each(response,function(key,value){

I like google gson library.
When you don't know structure of json. You can use
JsonElement root = new JsonParser().parse(jsonString);
and then you can work with json. e.g. how to get "value1" from your gson:
String value1 = root.getAsJsonObject().get("data").getAsJsonObject().get("field1").getAsString();
The reason is that your are defining your imageSegment
outside of a function in your source code (static variable).
In such cases, the initialization cannot include execution of code, like calling a function or allocation a class. Initializer must be a constant whose value is known at compile time.
You can then initialize your static variable inside of your init
method (if you postpone its declaration to init).
Scanner scan = new Scanner(System.in);
int i = scan.nextInt();
Double d = scan.nextDouble();
String newStr = "";
Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
while( charScanner.hasNext() ) {
String c = charScanner.next();
if (c.equalsIgnoreCase("\r")) {
break;
}
else {
newStr += c;
}
}
System.out.println("String: " + newStr);
System.out.println("Int: " + i);
System.out.println("Double: " + d);
This code works fine
Common reasons for the error:
=
) instead of equality (==
/===
)foo() = 42
instead of passing arguments (foo(42)
) getFoo() = 42
instead of getFoo().theAnswer = 42
or array indexing getArray() = 42
instead of getArray()[0]= 42
In this particular case you want to use ==
(or better ===
- What exactly is Type Coercion in Javascript?) to check for equality (like if(one === "rock" && two === "rock")
, but it the actual reason you are getting the error is trickier.
The reason for the error is Operator precedence. In particular we are looking for &&
(precedence 6) and =
(precedence 3).
Let's put braces in the expression according to priority - &&
is higher than =
so it is executed first similar how one would do 3+4*5+6
as 3+(4*5)+6
:
if(one= ("rock" && two) = "rock"){...
Now we have expression similar to multiple assignments like a = b = 42
which due to right-to-left associativity executed as a = (b = 42)
. So adding more braces:
if(one= ( ("rock" && two) = "rock" ) ){...
Finally we arrived to actual problem: ("rock" && two)
can't be evaluated to l-value that can be assigned to (in this particular case it will be value of two
as truthy).
Note that if you'd use braces to match perceived priority surrounding each "equality" with braces you get no errors. Obviously that also producing different result than you'd expect - changes value of both variables and than do &&
on two strings "rock" && "rock"
resulting in "rock"
(which in turn is truthy) all the time due to behavior of logial &&:
if((one = "rock") && (two = "rock"))
{
// always executed, both one and two are set to "rock"
...
}
For even more details on the error and other cases when it can happen - see specification:
LeftHandSideExpression = AssignmentExpression
...

This should happen automatically, so long as cms, admin and chart are all parts of the repository.
A likely issue is that each of these plugins is a git submodule.
Run git help submodule
for more information.
EDIT
For doing this in bash:
cd plugins
for f in cms admin chart
do
cd $f && git pull origin master && cd ..
done
You can close files not csv.writer object, it should be:
f = open(fileName, "wb")
writer = csv.writer(f)
String[] entries = "first*second*third".split("*");
writer.writerows(entries)
f.close()
Try this following program for 2d array in java:
public class ArrayTwo2 {
public static void main(String[] args) throws IOException,NumberFormatException{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
int[][] a;
int sum=0;
a=new int[3][2];
System.out.println("Enter array with 5 elements");
for(int i=0;i<a.length;i++)
{
for(int j=0;j<a[0].length;j++)
{
a[i][j]=Integer.parseInt(br.readLine());
}
}
for(int i=0;i<a.length;i++)
{
for(int j=0;j<a[0].length;j++)
{
System.out.print(a[i][j]+" ");
sum=sum+a[i][j];
}
System.out.println();
//System.out.println("Array Sum: "+sum);
sum=0;
}
}
}
var myColumnDefs = new Array();
for (var i = 0; i < oFullResponse.results.length; i++) {
myColumnDefs.push({key:oFullResponse.results[i].label, sortable:true, resizeable:true});
}
You can test this function
function html2text($Document) {
$Rules = array ('@<script[^>]*?>.*?</script>@si',

Python treats \
in literal string in a special way.
This is so you can type '\n'
to mean newline or '\t'
to mean tab
Since '\&'
doesn't mean anything special to Python, instead of causing an error, the Python lexical analyser implicitly adds the extra \
for you.
Really it is better to use \\&
or r'\&'
instead of '\&'
The r
here means raw string and means that \
isn't treated specially unless it is right before the quote character at the start of the string.
In the interactive console, Python uses repr
to display the result, so that is why you see the double '\'. If you print
your string or use len(string)
you will see that it is really only the 2 characters
Some examples
>>> 'Here\'s a backslash: \\'
"Here's a backslash: \\"
>>> print 'Here\'s a backslash: \\'
Here's a backslash: \
>>> 'Here\'s a backslash: \\. Here\'s a double quote: ".'
'Here\'s a backslash: \\. Here\'s a double quote: ".'
>>> print 'Here\'s a backslash: \\. Here\'s a double quote: ".'
Here's a backslash: \. Here's a double quote ".
To Clarify the point Peter makes in his comment see this link
Unlike Standard C, all unrecognized escape sequences are left in the string unchanged, i.e., the backslash is left in the string. (This behavior is useful when debugging: if an escape sequence is mistyped, the resulting output is more easily recognized as broken.) It is also important to note that the escape sequences marked as “(Unicode only)” in the table above fall into the category of unrecognized escapes for non-Unicode string literals.
To hide warnings, you can also do
{r, warning=FALSE}
You can filter
an array with a closure:
var myList = [1, 2, 3, 4]
var filtered = myList.filter { $0 == 3 } // <= returns [3]
And you can count an array:
filtered.count // <= returns 1
So you can determine if an array includes your element by combining these:
myList.filter { $0 == 3 }.count > 0 // <= returns true if the array includes 3
If you want to find the position, I don't see fancy way, but you can certainly do it like this:
var found: Int? // <= will hold the index if it was found, or else will be nil
for i in (0..x.count) {
if x[i] == 3 {
found = i
}
}
EDIT
While we're at it, for a fun exercise let's extend Array
to have a find
method:
extension Array {
func find(includedElement: T -> Bool) -> Int? {
for (idx, element) in enumerate(self) {
if includedElement(element) {
return idx
}
}
return nil
}
}
Now we can do this:
myList.find { $0 == 3 }
// returns the index position of 3 or nil if not found
I want to add the important hint that converting a project like this can have side effects which are noticeable when you have a larger project. This is due the fact that Intellij Idea (2017) takes some important settings only from the pom.xml then which can lead to some confusion, following sections are affected at least:
All these points need review and adjusting but after this it works like charm.
Further more unfortunately there is no sufficient pom.xml template created, I have added an example which might help to solve most problems.

Make sure Qt5Core.dll is in the same directory with your application executable.
I had a similar issue in Qt5 with a console application: if I start the application from Qt Creator, the output text is visible, if I open cmd.exe and start the same application there, no output is visible. Very strange!
I solved it by copying Qt5Core.dll to the directory with the application executable.
Here is my tiny console application:
#include <QCoreApplication>
#include <QDebug>
int main(int argc, char *argv[])
{
int x=343;
QString str("Hello World");
qDebug()<< str << x<<"lalalaa";
QTextStream out(stdout);
out << "aldfjals alsdfajs...";
}
If the OPENROWSET is causing you issues, there is another way from 2012 onwards; make use of sys.dm_exec_describe_first_result_set_for_object, as mentioned here: Retrieve column names and types of a stored procedure?
First, create this stored procedure to generate the SQL for the temporary table:
CREATE PROCEDURE dbo.usp_GetStoredProcTableDefinition(
@ProcedureName nvarchar(128),
@TableName nvarchar(128),
@SQL nvarchar(max) OUTPUT
)
AS
SET @SQL = 'CREATE TABLE ' + @tableName + ' ('
SELECT @SQL = @SQL + '['+name +'] '+ system_type_name +'' + ','
FROM sys.dm_exec_describe_first_result_set_for_object
(
OBJECT_ID(@ProcedureName),
NULL
);
--Remove trailing comma
SET @SQL = SUBSTRING(@SQL,0,LEN(@SQL))
SET @SQL = @SQL +')'
To use the procedure, call it in the following way:
DECLARE @SQL NVARCHAR(MAX)
exec dbo.usp_GetStoredProcTableDefinition
@ProcedureName='dbo.usp_YourProcedure',
@TableName='##YourGlobalTempTable',@SQL = @SQL OUTPUT
INSERT INTO ##YourGlobalTempTable
EXEC [dbo].usp_YourProcedure
select * from ##YourGlobalTempTable
Note that I'm using a global temporary table. That's because using EXEC to run the dynamic SQL creates its own session, so an ordinary temporary table would be out of scope to any subsequent code. If a global temporary table is a problem, you can use an ordinary temporary table, but any subsequent SQL would need to be dynamic, that is, also executed by the EXEC statement.
In using toolbar you should extends AppCompatActivity and
import android.support.v7.widget.Toolbar
You need to separate the arguments from the file path:
powershell.exe -noexit "& 'D:\Work\SQLExecutor.ps1 ' -gettedServerName 'MY-PC'"
Another option that may ease the syntax using the File parameter and positional parameters:
powershell.exe -noexit -file "D:\Work\SQLExecutor.ps1" "MY-PC"
Something like this?
>>> st = "hello world"
>>> ' '.join(format(ord(x), 'b') for x in st)
'1101000 1100101 1101100 1101100 1101111 100000 1110111 1101111 1110010 1101100 1100100'
#using `bytearray`
>>> ' '.join(format(x, 'b') for x in bytearray(st, 'utf-8'))
'1101000 1100101 1101100 1101100 1101111 100000 1110111 1101111 1110010 1101100 1100100'
You cannot use || operators in between 2 case. But you can use multiple case values without using a break between them. The program will then jump to the respective case and then it will look for code to execute until it finds a "break". As a result these cases will share the same code.
switch(value)
{
case 0:
case 1:
// do stuff for if case 0 || case 1
break;
// other cases
default:
break;
}
Another possible solution that works for me is something like -
cat a.txt | xargs bash -c 'command1 $@; command2 $@' bash
Note the 'bash' at the end - I assume it is passed as argv[0] to bash. Without it in this syntax the first parameter to each command is lost. It may be any word.
Example:
cat a.txt | xargs -n 5 bash -c 'echo -n `date +%Y%m%d-%H%M%S:` ; echo " data: " $@; echo "data again: " $@' bash
Annotate your field (or getter) with @Temporal(TemporalType.TIMESTAMP)
, like this:
public class MyEntity {
...
@Temporal(TemporalType.TIMESTAMP)
private java.util.Date myDate;
...
}
That should do the trick.
Did you try passwd -d root
? Most likely, this will do what you want.
You can also manually edit /etc/shadow
: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to
root:$X$SK5xfLB1ZW:0:0...
There, delete the second field (everything between the first and second colon):
root::0:0...
Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)
root:*:0:0...
Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d
, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd
, and use mkpasswd
to create the second field for the /etc/shadow.)
In case anyone's interested in the Method syntax, if you have a navigation property, it's way easy:
db.Services.Where(s=>s.ServiceAssignment.LocationId == 1);
If you don't, unless there's some Join()
override I'm unaware of, I think it looks pretty gnarly (and I'm a Method syntax purist):
db.Services.Join(db.ServiceAssignments,
s => s.Id,
sa => sa.ServiceId,
(s, sa) => new {service = s, asgnmt = sa})
.Where(ssa => ssa.asgnmt.LocationId == 1)
.Select(ssa => ssa.service);

When trying to generate a random password you are trying to :
First generate a cryptographically secure set of random bytes
Second is turning those random bytes into a printable string
Now, there are multiple way to generate random bytes in php like :
$length = 32;
//PHP 7+
$bytes= random_bytes($length);
//PHP < 7
$bytes= openssl_random_pseudo_bytes($length);
Then you want to turn these random bytes into a printable string :
You can use bin2hex :
$string = bin2hex($bytes);
or base64_encode :
$string = base64_encode($bytes);
However, note that you do not control the length of the string if you use base64. You can use bin2hex to do that, using 32 bytes will turn into a 64 char string. But it will only work like so in an EVEN string.
So basically you can just do :
$length = 32;
if(PHP_VERSION>=7){
$bytes= random_bytes($length);
}else{
$bytes= openssl_random_pseudo_bytes($length);
}
$string = bin2hex($bytes);
What type of granularity are you looking for? You can typically get by with:
$http.get(url).then(
//success function
function(results) {
//do something w/results.data
},
//error function
function(err) {
//handle error
}
);
I've found that "finally" and "catch" are better off when chaining multiple promises.
Option 1 :
org.apache.commons.lang3.LocaleUtils.toLocale("en_US")
Option 2 :
Locale.forLanguageTag("en-US")
Please note Option 1 is "underscore" between language and country , and Option 2 is "dash".
How to find out what this MySQL Error is trying to say:
#1064 - You have an error in your SQL syntax;
This error has no clues in it. You have to double check all of these items to see where your mistake is:
!@#$%^&*()-_=+[]{}\|;:'",<>/?
select
, into
, or countless others. Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.
I am not sure I got you but this might be what you are looking for:
SELECT i.invoiceid, sum(case when i.amount is not null then i.amount else 0 end), sum(case when i.amount is not null then i.amount else 0 end) - sum(case when p.amount is not null then p.amount else 0 end) AS amountdue
FROM invoices i
LEFT JOIN invoicepayments ip ON i.invoiceid = ip.invoiceid
LEFT JOIN payments p ON ip.paymentid = p.paymentid
LEFT JOIN customers c ON p.customerid = c.customerid
WHERE c.customernumber = '100'
GROUP BY i.invoiceid
This would get you the amounts sums in case there are multiple payment rows for each invoice

For references and the future, one should read the doc here https://dev.mysql.com/doc/mysql-secure-deployment-guide/5.7/en/secure-deployment-password-validation.html
Then you should edit your mysqld.cnf
file, for instance :
vim /etc/mysql/mysql.conf.d/mysqld.cnf
Then, add in the [mysqld] part, the following :
plugin-load-add=validate_password.so
validate_password_policy=LOW
Basically, if you edit your default, it will looks like :
[mysqld]
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
plugin-load-add=validate_password.so
validate_password_policy=LOW
Then, you can restart:
systemctl restart mysql
If you forget the plugin-load-add=validate_password.so
part, you will it an error at restart.

'OR 1=1
is an attempt to make a query succeed no matter what
The /*
is an attempt to start a multiline comment so the rest of the query is ignored.
An example would be
SELECT userid
FROM users
WHERE username = ''OR 1=1/*'
AND password = ''
AND domain = ''
As you can see if you were to populate the username field without escaping the '
no matter what credentials the user passes in the query would return all userids in the system likely granting access to the attacker (possibly admin access if admin is your first user). You will also notice the remainder of the query would be commented out because of the /*
including the real '
.
The fact that you can see the value in your database means that it was escaped and that particular attack did not succeed. However, you should investigate if any other attempts were made.
Assuming you mean the HTML type RGB codes (called Hex codes, such as #FFCC66), use the ColorTranslator class:
System.Drawing.Color col = System.Drawing.ColorTranslator.FromHtml("#FFCC66");
If, however you are using an ARGB hex code, you can use the ColorConverter class from the System.Windows.Media namespace:
Color col = ColorConverter.ConvertFromString("#FFDFD991") as Color;
//or = (Color) ColorConverter.ConvertFromString("#FFCC66") ;

Generally, I agree with @kgrittn's advice. Go for it.
But to address your basic question about concat()
: The new function concat()
is useful if you need to deal with null values - and null has neither been ruled out in your question nor in the one you refer to.
If you can rule out null values, the good old (SQL standard) concatenation operator ||
is still the best choice, and @luis' answer is just fine:
SELECT col_a || col_b;
If either of your columns can be null, the result would be null in that case. You could defend with COALESCE
:
SELECT COALESCE(col_a, '') || COALESCE(col_b, '');
But that get tedious quickly with more arguments. That's where concat()
comes in, which never returns null, not even if all arguments are null. Per documentation:
NULL arguments are ignored.
SELECT concat(col_a, col_b);
The remaining corner case for both alternatives is where all input columns are null in which case we still get an empty string ''
, but one might want null instead (at least I would). One possible way:
SELECT CASE
WHEN col_a IS NULL THEN col_b
WHEN col_b IS NULL THEN col_a
ELSE col_a || col_b
END;
This gets more complex with more columns quickly. Again, use concat()
but add a check for the special condition:
SELECT CASE WHEN (col_a, col_b) IS NULL THEN NULL
ELSE concat(col_a, col_b) END;
How does this work?
(col_a, col_b)
is shorthand notation for a row type expression ROW (col_a, col_b)
. And a row type is only null if all columns are null. Detailed explanation:
Also, use concat_ws()
to add separators between elements (ws
for "with separator").
An expression like the one in Kevin's answer:
SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;
is tedious to prepare for null values in PostgreSQL 8.3 (without concat()
). One way (of many):
SELECT COALESCE(
CASE
WHEN $1.zipcode IS NULL THEN $1.city
WHEN $1.city IS NULL THEN $1.zipcode
ELSE $1.zipcode || ' - ' || $1.city
END, '')
|| COALESCE(', ' || $1.state, '');
STABLE
concat()
and concat_ws()
are STABLE
functions, not IMMUTABLE
because they can invoke datatype output functions (like timestamptz_out
) that depend on locale settings.
Explanation by Tom Lane.
This prohibits their direct use in index expressions. If you know that the result is actually immutable in your case, you can work around this with an IMMUTABLE
function wrapper. Example here:
if you're goal is to reset EVERYTHING then @Björn's answer should be your goal but applied as:
* {
padding: initial;
}
if this is loaded after your original reset.css should have the same weight and will rely on each browser's default padding as initial value.

You can think of an iframe as an embedded browser window that you can put on an HTML page to show another URL inside it. This URL can be totally distinct from your web site/app.
You can put an iframe in any HTML page, so you could put one inside a contentplaceholder in a webform that has a Masterpage and it will appear with whatever URL you load into it (via Javascript, or C# if you turn your iframe into a server-side control (runat='server'
) on the final HTML page that your webform produces when requested.
And you can load a URL into your iframe that is a .aspx
page.
But - iframes have nothing to do with the ASP.net mechanism. They are HTML elements that can be made to run server-side, but they are essentially 'dumb' and unmanaged/unconnected to the ASP.Net mechanisms - don't confuse a Contentplaceholder with an iframe.
Incidentally, the use of iframes is still contentious - do you really need to use one? Can you afford the negative trade-offs associated with them e.g. lack of navigation history ...?
Answers so far helped me come up with mine. I'm wary of UTC vs local time; ticks should always be UTC IMO.
public class Time
{
public static void Timestamps()
{
OutputTimestamp();
Thread.Sleep(1000);
OutputTimestamp();
}
private static void OutputTimestamp()
{
var timestamp = DateTime.UtcNow.Ticks;
var localTicks = DateTime.Now.Ticks;
var localTime = new DateTime(timestamp, DateTimeKind.Utc).ToLocalTime();
Console.Out.WriteLine("Timestamp = {0}. Local ticks = {1}. Local time = {2}.", timestamp, localTicks, localTime);
}
}
Output:
Timestamp = 636988286338754530. Local ticks = 636988034338754530. Local time = 2019-07-15 4:03:53 PM.
Timestamp = 636988286348878736. Local ticks = 636988034348878736. Local time = 2019-07-15 4:03:54 PM.
I know no-one is asking for a jQuery solution here, but might be worth mentioning that with jQuery you can just ask for:$('#selectorid').val()
Using the default instance (i.e., MSSQLSERVER, use the DOT (.))
<add name="CONNECTION_STRING_NAME" connectionString="Data Source=.;Initial Catalog=DATABASE_NAME;Integrated Security=True;" />
The reason is your base class is not public-ed, then Mockito cannot intercept it due to visibility, if you change base class as public, or @Override in sub class (as public), then Mockito can mock it correctly.
public class BaseService{
public boolean foo(){
return true;
}
}
public ChildService extends BaseService{
}
@Test
@Mock ChildService childService;
public void testSave() {
Mockito.when(childService.foo()).thenReturn(false);
// When
assertFalse(childService.foo());
}
Some given answers don't have in consideration the current day!
Here it is my proposal.
$var = "2010-01-21 00:00:00.0"
$given_date = new \DateTime($var);
if ($given_date == new \DateTime('today')) {
//today
}
if ($given_date < new \DateTime('today')) {
//past
}
if ($given_date > new \DateTime('today')) {
//future
}
Content-Type:application/json
When you define any POST request method input parameter that should be annotated as [FromBody]
, e.g.:
[HttpPost]
public HttpResponseMessage Post([FromBody]ActivityResult ar)
{
return new HttpResponseMessage(HttpStatusCode.OK);
}
Any JSON input data must be raw data.
You can always use a background image to do it too. I tend to vote for this option 100% of the time as the only other perfect solution is the Jquery option.
As with using the outer div with a background color you'll end up having to have the content in both divs reaching the same height.
For Java 8 and above, it's easy:
when(mock.process(Matchers.anyList()));
For Java 7 and below, the compiler needs a bit of help. Use anyListOf(Class<T> clazz)
:
when(mock.process(Matchers.anyListOf(Bar.class)));
You can use this
File dir=new File(TestMain.class.getClassLoader().getResource("filename").getPath());
iReports Custom Fields for columns (sum, average, etc)
Right-Click on Variables and click Create Variable
Click on the new variable
a. Notice the properties on the right
Rename the variable accordingly
Change the Value Class Name to the correct Data Type
a. You can search by clicking the 3 dots
Select the correct type of calculation
Change the Expression
a. Click the little icon
b. Select the column you are looking to do the calculation for
c. Click finish
Set Initial Value Expression to 0
Set the increment type to none
Set the Reset Type (usually report)
Drag a new Text Field to stage (Usually in Last Page Footer, or Column Footer)
Select the new variable
Click finish
Yes, there is (see link in Matt Hamilton's comment), but it would be easier and better to use .NET's IO classes. You can use File.ReadAllBytes to read the files and then File.WriteAllBytes to write the "embedded" version.
I was getting this on an asp.net 2.0 iis7 Windows2008 site. Same code on iis6 worked fine. It was causing an issue for me because it was messing up the login process. User would login and get a 302 to default.asxp, which would get through page_load, but not as far as pre-render before iis7 would send a 302 back to login.aspx without the auth cookie. I started playing with app pool settings, and for some reason 'enable 32 bit applications' seems to have fixed it. No idea why, since this site isn't doing anything special that should require any 32 bit drivers. We have some sites that still use Access that require 32bit, but not our straight SQL sites like this one.
In pyspark,SparkSql syntax:
where column_n like 'xyz%'
might not work.
Use:
where column_n RLIKE '^xyz'
This works perfectly fine.
If you have set public access for bucket and if it is still not working, edit bucker policy and paste following:
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"s3:PutObject",
"s3:PutObjectAcl",
"s3:GetObject",
"s3:GetObjectAcl",
"s3:DeleteObject"
],
"Resource": [
"arn:aws:s3:::yourbucketnamehere",
"arn:aws:s3:::yourbucketnamehere/*"
],
"Effect": "Allow",
"Principal": "*"
}
]
}
I had this same problem and solved it by adding an event handler for the play action in addition to the click action. I hide the controls while playing to avoid the pause button issue.
var v = document.getElementById('videoID');
v.addEventListener(
'play',
function() {
v.play();
},
false);
v.onclick = function() {
if (v.paused) {
v.play();
v.controls=null;
} else {
v.pause();
v.controls="controls";
}
};
Seeking still acts funny though, but at least the confusion with the play control is gone. Hope this helps.
Anyone have a solution to that?
You can template a struct as well as a class. However you can't template a typedef. So template<typename T> struct array {...};
works, but template<typename T> typedef struct {...} array;
does not. Note that there is no need for the typedef trick in C++ (you can use structs without the struct
modifier just fine in C++).
For exe files, I suppose the differences are nearly unimportant.
But to start an exe you don't even need CALL
.
When starting another batch it's a big difference,
as CALL
will start it in the same window and the called batch has access to the same variable context.
So it can also change variables which affects the caller.
START
will create a new cmd.exe for the called batch and without /b it will open a new window.
As it's a new context, variables can't be shared.
Using start /wait <prog>
- Changes of environment variables are lost when the <prog>
ends
- The caller waits until the <prog>
is finished
Using call <prog>
- For exe it can be ommited, because it's equal to just starting <prog>
- For an exe-prog the caller batch waits or starts the exe asynchronous, but the behaviour depends on the exe itself.
- For batch files, the caller batch continues, when the called <batch-file>
finishes, WITHOUT call the control will not return to the caller batch
Using CALL
can change the parameters (for batch and exe files), but only when they contain carets or percent signs.
call myProg param1 param^^2 "param^3" %%path%%
Will be expanded to (from within an batch file)
myProg param1 param2 param^^3 <content of path>
Here's a simple helper function that I created modeled after the above answers, tailored to a Babel environment:
import { isEmpty } from 'lodash'
export default function unflattenEntities(entities, parent = {id: null}, tree = []) {
let children = entities.filter( entity => entity.parent_id == parent.id)
if (!isEmpty( children )) {
if ( parent.id == null ) {
tree = children
} else {
parent['children'] = children
}
children.map( child => unflattenEntities( entities, child ) )
}
return tree
}
If there is an on-screen keyboard, focusing a text field that is near the bottom of the viewport will cause Safari to scroll the text field into view. There might be some way to exploit this phenomenon to detect the presence of the keyboard (having a tiny text field at the bottom of the page which gains focus momentarily, or something like that).
I would write the code like this:
def search_book(request):
form = SearchForm(request.POST or None)
if request.method == "POST" and form.is_valid():
stitle = form.cleaned_data['title']
sauthor = form.cleaned_data['author']
scategory = form.cleaned_data['category']
return HttpResponseRedirect('/thanks/')
return render_to_response("books/create.html", {
"form": form,
}, context_instance=RequestContext(request))
Pretty much like the documentation.
Number of a columns in the result set you can get with code (as DB is used PostgreSQL):
//load the driver for PostgreSQL Class.forName("org.postgresql.Driver"); String url = "jdbc:postgresql://localhost/test"; Properties props = new Properties(); props.setProperty("user","mydbuser"); props.setProperty("password","mydbpass"); Connection conn = DriverManager.getConnection(url, props); //create statement Statement stat = conn.createStatement(); //obtain a result set ResultSet rs = stat.executeQuery("SELECT c1, c2, c3, c4, c5 FROM MY_TABLE"); //from result set give metadata ResultSetMetaData rsmd = rs.getMetaData(); //columns count from metadata object int numOfCols = rsmd.getColumnCount();
But you can get more meta-informations about columns:
for(int i = 1; i <= numOfCols; i++)
{
System.out.println(rsmd.getColumnName(i));
}
And at least but not least, you can get some info not just about table but about DB too, how to do it you can find here and here.
Putting a @
in front of a string enables you to use special characters such as a backslash or double-quotes without having to use special codes or escape characters.
So you can write:
string path = @"C:\My path\";
instead of:
string path = "C:\\My path\\";
@FXML
ImageView image;
@Override
public void initialize(URL url, ResourceBundle rb) {
image.setImage(new Image ("/about.jpg"));
}
Creating a Guava BiMap and getting its inverted value is not so trivial.
A simple example:
import com.google.common.collect.BiMap;
import com.google.common.collect.HashBiMap;
public class BiMapTest {
public static void main(String[] args) {
BiMap<String, String> biMap = HashBiMap.create();
biMap.put("k1", "v1");
biMap.put("k2", "v2");
System.out.println("k1 = " + biMap.get("k1"));
System.out.println("v2 = " + biMap.inverse().get("v2"));
}
}
If the commit you want to revert is a merged commit (has been merged already), then you should either -m 1
or -m 2
option as shown below. This will let git know which parent commit of the merged commit to use. More details can be found HERE.
git revert <commit> -m 1
git revert <commit> -m 2
Usually what you choose will depend on which methods you need access to. In general - IEnumerable<>
(MSDN: http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.aspx) for a list of objects that only needs to be iterated through, ICollection<>
(MSDN: http://msdn.microsoft.com/en-us/library/92t2ye13.aspx) for a list of objects that needs to be iterated through and modified, List<>
for a list of objects that needs to be iterated through, modified, sorted, etc (See here for a full list: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx).
From a more specific standpoint, lazy loading comes in to play with choosing the type. By default, navigation properties in Entity Framework come with change tracking and are proxies. In order for the dynamic proxy to be created as a navigation property, the virtual type must implement ICollection
.
A navigation property that represents the "many" end of a relationship must return a type that implements ICollection, where T is the type of the object at the other end of the relationship. -Requirements for Creating POCO ProxiesMSDN
I'll add that arrays are very low-level constructs in C++ and you should try to stay away from them as much as possible when "learning the ropes" -- even Bjarne Stroustrup recommends this (he's the designer of C++).
Vectors come very close to the same performance as arrays, but with a great many conveniences and safety features. You'll probably start using arrays when interfacing with API's that deal with raw arrays, or when building your own collections.
The answer by @chepner will copy all the sub-directories irrespective of the fact if it contains the file or not. If you need to exclude the sub-directories that dont contain the file and still retain the directory structure, use
rsync -zarv --prune-empty-dirs --include "*/" --include="*.sh" --exclude="*" "$from" "$to"
foreach( $codes as $code and $names as $name ) { }
That is not valid.
You probably want something like this...
foreach( $codes as $index => $code ) {
echo '<option value="' . $code . '">' . $names[$index] . '</option>';
}
Alternatively, it'd be much easier to make the codes the key of your $names
array...
$names = array(
'tn' => 'Tunisia',
'us' => 'United States',
...
);
You can use the unzip
command.
SQL NULL's special, and you have to do WHERE field IS NULL
, as NULL cannot be equal to anything,
including itself (ie: NULL = NULL is always false).
You should assign string value to environment variable.
os.environ["DEBUSSY"] = "1"
If you want to read or print the environment variable just use
print os.environ["DEBUSSY"]
This changes will be effective only for the current process where it was assigned, it will no change the value permanently. The child processes will automatically inherit the environment of the parent process.
That is my code, dont forget = object: if don't put don't works

UPDATE: I have created a video on sending multipart/form-data requests to explain this better.
Actually, Postman can do this. Here is a screenshot
Newer version : Screenshot captured from postman chrome extension

Make sure you check the comment from @maxkoryukov
Be careful with explicit Content-Type header. Better - do not set it's value, the Postman is smart enough to fill this header for you. BUT, if you want to set the Content-Type: multipart/form-data - do not forget about boundary field.
Here is what you need to do -
Download openSSl from Code Extract it. create a folder- OpenSSL in C:/ and copy the extracted code here.
detect debug.keystore file path. If u didn't find, then do a search in C:/ and use the Path in the command in next step.
detect your keytool.exe path and go to that dir/ in command prompt and run this command in 1 line-
$ keytool -exportcert -alias androiddebugkey -keystore "C:\Documents and Settings\Administrator.android\debug.keystore" | "C:\OpenSSL\bin\openssl" sha1 -binary |"C:\OpenSSL\bin\openssl" base64
it will ask for password, put android that's all. u will get a key-hash

As usual in Angular, you can rely on dependency injection:
import { DatePipe } from '@angular/common';
class MyService {
constructor(private datePipe: DatePipe) {}
transformDate(date) {
return this.datePipe.transform(date, 'yyyy-MM-dd');
}
}
Add DatePipe
to your providers list in your module; if you forget to do this you'll get an error no provider for DatePipe
:
providers: [DatePipe,...]
Update Angular 6: Angular 6 now offers pretty much every formatting functions used by the pipes publicly. For example, you can now use the formatDate
function directly.
import { formatDate } from '@angular/common';
class MyService {
constructor(@Inject(LOCALE_ID) private locale: string) {}
transformDate(date) {
return formatDate(date, 'yyyy-MM-dd', this.locale);
}
}
Before Angular 5: Be warned though that the DatePipe
was relying on the Intl API until version 5, which is not supported by all browsers (check the compatibility table).
If you're using older Angular versions, you should add the Intl
polyfill to your project to avoid any problem.

Just define the target page in the action
attribute of the <form>
containing the submit button.
So, in page1.jsp
:
<form action="page2.jsp">
<input type="submit">
</form>
Unrelated to the problem, a JSP is not the best place to do business stuff, if you need to do any. Consider learning servlets.
None of these suggestions above worked for me as-is. I had to use the following to center a checkbox with the label text displayed to the right of the box:
<style>
.checkboxes {
display: flex;
justify-content: center;
align-items: center;
vertical-align: middle;
word-wrap: break-word;
}
</style>
<label for="checkbox1" class="checkboxes"><input type="checkbox" id="checkbox1" name="checked" value="yes" class="checkboxes"/>
Check the box.</label>
The simplest way to get tooltips in most browsers is to set some text in the title attribute.
eg.
<img src="myimage.jpg" alt="a cat" title="My cat sat on a table" />
produces (hover your mouse over the image):
a cat http://www.imagechicken.com/uploads/1275939952008633500.jpg
Title attributes can be applied to most HTML elements.

We render the PDF file pages as PNG files on the server using JPedal (a java library). That, combined with some javascript, gives us high control over visualization and navigation.
I think you have to include jQuery to use responseJSON
.
Without jQuery, you could try with responseText and try like eval("("+req.responseText+")");
UPDATE:Please read the comment regarding eval
, you can test with eval, but don't use it in working extension.
OR
use json_parse : it does not use eval

Invoke-WebRequest can download HTTP, HTTPS, and FTP links.
$source = 'ftp://Blah.com/somefile.txt'
$target = 'C:\Users\someuser\Desktop\BlahFiles\somefile.txt'
$password = Microsoft.PowerShell.Security\ConvertTo-SecureString -String 'mypassword' -AsPlainText -Force
$credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList myuserid, $password
# Download
Invoke-WebRequest -Uri $source -OutFile $target -Credential $credential -UseBasicParsing
Since the cmdlet uses IE parsing you may need the -UseBasicParsing switch. Test to make sure.
You need to call srand()
once, to randomize the seed, and then call rand()
in your loop:
#include <stdlib.h>
#include <time.h>
#define size 10
srand(time(NULL)); // randomize seed
for(i=0;i<size;i++)
Arr[i] = rand()%size;
Using the out keyword with a return type of bool, can sometimes reduce code bloat and increase readability. (Primarily when the extra info in the out param is often ignored.) For instance:
var result = DoThing();
if (result.Success)
{
result = DoOtherThing()
if (result.Success)
{
result = DoFinalThing()
if (result.Success)
{
success = true;
}
}
}
vs:
var result;
if (DoThing(out result))
{
if (DoOtherThing(out result))
{
if (DoFinalThing(out result))
{
success = true;
}
}
}

apparently, the GET and/or the POST variable(s) do(es) not exist. simply test if "isset". (pseudocode):
if(isset($_GET['action'];)) {$action = $_GET['action'];} else { RECOVER FROM ERROR CODE }
Yes, there is a difference. Continue

Using two datasources you need their own transaction managers.
@Configuration
public class MySqlDBConfig {
@Bean
@Primary
@ConfigurationProperties(prefix="datasource.test.mysql")
public DataSource mysqlDataSource(){
return DataSourceBuilder
.create()
.build();
}
@Bean("mysqlTx")
public DataSourceTransactionManager mysqlTx() {
return new DataSourceTransactionManager(mysqlDataSource());
}
// same for another DS
}
And then use it accordingly within @Transaction
@Transactional("mysqlTx")
@Repository
public interface UserMysqlDao extends CrudRepository<UserMysql, Integer>{
public UserMysql findByName(String name);
}
In addition to the existing answer it is possible to set a default option as follows:
echo off
ECHO A current build of Test Harness exists.
set delBuild=n
set /p delBuild=Delete preexisting build [y/n] (default - %delBuild%)?:
This allows users to simply hit "Enter" if they want to enter the default.
You can also initialize the list with an array directly:
List<int> mylist= new List<int>(new int[]{6, 1, -5, 4, -2, -3, 9});
If you use the WebStorm Javascript IDE, you can just open your project from WebStorm in your browser. WebStorm will automatically start a server and you won't get any of these errors anymore, because you are now accessing the files with the allowed/supported protocols (HTTP).
Pretty strange, it should work out of the box as the ".modal-backdrop" class is defined top-level in the css.

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.
So, you should use ready in a bit different way
$.ready(function() {
createGrid();
});
This is in case when you dont use AJAX to load your div
