According to the official documentation on sitemaps.org it needs to be a full URL:
You can specify the location of the Sitemap using a robots.txt file. To do this, simply add the following line including the full URL to the sitemap:
Sitemap: http://www.example.com/sitemap.xml
It must be because of commit is ahead of your current push.
git pull origin "name of branch you want to push"
git rebase
If git rebase is successful, then good. Otherwise, you have resolve all merge conflicts locally and keep it continuing until rebase with remote is successful.

Your code was compiled with Java 8.
Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.
Hope this helps...
Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable
Type in command line
echo %JAVA_HOME%
and
java -version
To verify whether your installation was done successfully.
This problem generally occurs in Windows when your "Java Runtime Environment" registry entry is missing or mismatched with the installed JDK. The mismatch can be due to multiple JDKs.
Steps to resolve:
Open the Run window:
Press windows+R
Open registry window:
Type regedit
and enter.
Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\
If Java Runtime Environment is not present inside JavaSoft, then create a new Key and give the name Java Runtime Environment.
For Java Runtime Environment create "CurrentVersion" String Key and give appropriate version as value:
Create a new subkey of 1.8.
For 1.8 create a String Key with name JavaHome with the value of JRE home:

I cannot comment on @Michael Blackburn, but I guess you got the downvote because the GroupBy is not necessary in this case.
Use it like:
var lookupOfCustomObjects = listOfCustomObjects.ToLookup(o=>o.PropertyName);
var listWithAllCustomObjectsWithPropertyName = lookupOfCustomObjects[propertyName]
Additionally, I've seen this perform way better than when using GroupBy().ToDictionary().
The most readable way is
x = 10 if a > b else 11
but you can use and
and or
, too:
x = a > b and 10 or 11
The "Zen of Python" says that "readability counts", though, so go for the first way.
Also, the and-or trick will fail if you put a variable instead of 10
and it evaluates to False
.
However, if more than the assignment depends on this condition, it will be more readable to write it as you have:
if A[i] > B[j]:
x = A[i]
i += 1
else:
x = A[j]
j += 1
unless you put i
and j
in a container. But if you show us why you need it, it may well turn out that you don't.
What ever attribute is added to the button/anchor/link to disable it, bootstrap is just adding style to it and user will still be able to click it while there is still onclick event. So my simple solution is to check if it is disabled and remove/add onclick event:
if (!('#button').hasAttr('disabled'))
$('#button').attr('onclick', 'someFunction();');
else
$('#button').removeattr('onclick');
The best practice would be to create a module separately which has only one method whose task we be to give a logger handler to the the calling method. Save this file as m_logger.py
import logger, logging
def getlogger():
# logger
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
# create console handler and set level to debug
#ch = logging.StreamHandler()
ch = logging.FileHandler(r'log.txt')
ch.setLevel(logging.DEBUG)
# create formatter
formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
# add formatter to ch
ch.setFormatter(formatter)
# add ch to logger
logger.addHandler(ch)
return logger
Now call the getlogger() method whenever logger handler is needed.
from m_logger import getlogger
logger = getlogger()
logger.info('My mssg')
Here's an alternative regular expression:
^(?=(.{4})*$)[A-Za-z0-9+/]*={0,2}$
It satisfies the following conditions:
(?=^(.{4})*$)
[A-Za-z0-9+/]*
={0,2}
In my case I was trying to delete entries that were saved in .git/packed-refs
. You can edit this plain text file and delete entries from it that git br -D
doesn't know how to touch (At least in ver 1.7.9.5).
I found this solution here: https://stackoverflow.com/a/11050880/1695680
I think you have to write each object to an own File or you have to split the one when reading it. You may also try to serialize your list and retrieve that when deserializing.
Using the --mirror
option seems to copy the remote
tracking branches properly.
However, it sets up the repository as a bare repository, so you have to turn it back into a normal repository afterwards.
git clone --mirror path/to/original path/to/dest/.git
cd path/to/dest
git config --bool core.bare false
git checkout anybranch
Reference: Git FAQ: How do I clone a repository with all remotely tracked branches?
At its simplest:
#include <iostream>
using namespace std;
class A {
public:
A( int x ) : n( x ){}
void print() { cout << n << endl; }
private:
int n;
};
void func( A p ) {
p.print();
}
int main () {
A a;
func ( a );
}
Of course, you should probably be using references to pass the object, but I suspect you haven't got to them yet.
If the class uses as a parameterized type, it can declare an array of type T[], but it cannot directly instantiate such an array. Instead, a common approach is to instantiate an array of type Object[], and then make a narrowing cast to type T[], as shown in the following:
public class Portfolio<T> {
T[] data;
public Portfolio(int capacity) {
data = new T[capacity]; // illegal; compiler error
data = (T[]) new Object[capacity]; // legal, but compiler warning
}
public T get(int index) { return data[index]; }
public void set(int index, T element) { data[index] = element; }
}
I would use Pandas with col number
f = pd.read_csv("test.csv", usecols=[0,1,3,4])
f.to_csv("test.csv", index=False)
If none of the answers helps, you might need to adjust the project properties. Check this other StackOverflow answer on how to do that:
You can associate directly the function object window.destroy
to the command
attribute of your button
:
button = Button (frame, text="Good-bye.", command=window.destroy)
This way you will not need the function close_window
to close the window for you.
To resolve this problem set value for apc.shm_size as integer Locate your apc.ini file (In my system apc.ini file location /etc/php5/conf.d/apc.ini) and set: apc.shm_size = 1000
I have also noticed that cordova has a "serve" command that Phonegap doesn't. This command launches a local server on port 8000. This is handy for running your app in Chrome and using the Ripple emulator.
I tried almost all of above but did not work for me ... The following did

I've made a proof-of-concept solution using jQuery.
I've now got this code in a Mercurial bitbucket repository. The main file is tables.html
.
I'm aware of one issue with this: if the table contains anchors, and if you open the URL with the specified anchor in a browser, when the page loads, the row with the anchor will probably be obscured by the floating header.
Update 2017-12-11: I see this doesn't work with current Firefox (57) and Chrome (63). Not sure when and why this stopped working, or how to fix it. But now, I think the accepted answer by Hendy Irawan is superior.
JavaScript With Selenium WebDriver
Selenium is one of the most popular automated testing suites. Selenium is designed in a way to support and encourage automation testing of functional aspects of web based applications and a wide range of browsers and platforms.
public static WebDriver driver;
public static void main(String[] args) {
driver = new FirefoxDriver(); // This opens a window
String url = "----";
/*driver.findElement(By.id("username")).sendKeys("yashwanth.m");
driver.findElement(By.name("j_password")).sendKeys("yashwanth@123");*/
JavascriptExecutor jse = (JavascriptExecutor) driver;
if (jse instanceof WebDriver) {
//Launching the browser application
jse.executeScript("window.location = \'"+url+"\'");
jse.executeScript("document.getElementById('username').value = \"yash\";");
// Tag having name then
driver.findElement(By.xpath(".//input[@name='j_password']")).sendKeys("admin");
//Opend Site and click on some links. then you can apply go(-1)--> back forword(-1)--> front.
//Refresheing the web-site. driver.navigate().refresh();
jse.executeScript("window.history.go(0)");
jse.executeScript("window.history.go(-2)");
jse.executeScript("window.history.forward(-2)");
String title = (String)jse.executeScript("return document.title");
System.out.println(" Title Of site : "+title);
String domain = (String)jse.executeScript("return document.domain");
System.out.println("Web Site Domain-Name : "+domain);
// To get all NodeList[1052] document.querySelectorAll('*'); or document.all
jse.executeAsyncScript("document.getElementsByTagName('*')");
String error=(String) jse.executeScript("return window.jsErrors");
System.out.println("Windowerrors : "+error);
System.out.println("To Find the input tag position from top");
ArrayList<?> al = (ArrayList<?>) jse.executeScript(
"var source = [];"+
"var inputs = document.getElementsByTagName('input');"+
"for(var i = 0; i < inputs.length; i++) { " +
" source[i] = inputs[i].offsetParent.offsetTop" + //" inputs[i].type = 'radio';"
"}"+
"return source"
);//inputs[i].offsetParent.offsetTop inputs[i].type
System.out.println("next");
System.out.println("array : "+al);
// (CTRL + a) to access keyboard keys. org.openqa.selenium.Keys
Keys k = null;
String selectAll = Keys.chord(Keys.CONTROL, "a");
WebElement body = driver.findElement(By.tagName("body"));
body.sendKeys(selectAll);
// Search for text in Site. Gets all ViewSource content and checks their.
if (driver.getPageSource().contains("login")) {
System.out.println("Text present in Web Site");
}
Long clent_height = (Long) jse.executeScript("return document.body.clientHeight");
System.out.println("Client Body Height : "+clent_height);
// using selenium we con only execute script but not JS-functions.
}
driver.quit(); // to close browser
}
To Execute User-Functions, Writing JS in to a file and reading as String and executing it to easily use.
Scanner sc = new Scanner(new FileInputStream(new File("JsFile.txt")));
String js_TxtFile = "";
while (sc.hasNext()) {
String[] s = sc.next().split("\r\n");
for (int i = 0; i < s.length; i++) {
js_TxtFile += s[i];
js_TxtFile += " ";
}
}
String title = (String) jse.executeScript(js_TxtFile);
System.out.println("Title : "+title);
document.title & document.getElementById() is a property/method available in Browsers.

var title = getTitle();
return title;
function getTitle() {

I had the same problem with PHP. I solved it by changing "localhost" to "127.0.0.1" in database connection parameters like someone suggested here: https://serverfault.com/a/444338/62739 . I think it may work for you too, give it a try.
This won't be secure, and it's simple to explain why:
If you hash the password on the client side and use that token instead of the password, then an attacker will be unlikely to find out what the password is.
But, the attacker doesn't need to find out what the password is, because your server isn't expecting the password any more - it's expecting the token. And the attacker does know the token because it's being sent over unencrypted HTTP!
Now, it might be possible to hack together some kind of challenge/response form of encryption which means that the same password will produce a different token each request. However, this will require that the password is stored in a decryptable format on the server, something which isn't ideal, but might be a suitable compromise.
And finally, do you really want to require users to have javascript turned on before they can log into your website?
In any case, SSL is neither an expensive or especially difficult to set up solution any more
Since I'm disturbed by the verbosity of some of the new NUnit patterns, I use something like this to create code that is cleaner for me personally:
public void AssertBusinessRuleException(TestDelegate code, string expectedMessage)
{
var ex = Assert.Throws<BusinessRuleException>(code);
Assert.AreEqual(ex.Message, expectedMessage);
}
public void AssertException<T>(TestDelegate code, string expectedMessage) where T:Exception
{
var ex = Assert.Throws<T>(code);
Assert.AreEqual(ex.Message, expectedMessage);
}
The usage is then:
AssertBusinessRuleException(() => user.MakeUserActive(), "Actual exception message");
The EASIEST way to change WITHOUT modifying the underlying data is:
as_labeller
function adding the back tick mark for each of the default values:# Necessary to put RH% into the facet labels
hum.names <- as_labeller(
c(`50` = "RH% 50", `60` = "RH% 60",`70` = "RH% 70",
`80` = "RH% 80",`90` = "RH% 90", `100` = "RH% 100"))
ggplot(dataframe, aes(x = Temperature.C, y = fit)) +
geom_line() +
facet_wrap(~Humidity.RH., nrow = 2, labeller = hum.names)
#mydiv:before {
content: url("data:image/svg+xml; utf8, <svg.. code here</svg>");
display:block;
width:22px;
height:10px;
margin:10px 5px 0 10px;
}
make sure your svg doesn't contain double quotes, and uriencode any # symbols.

Look at the exception:
No qualifying bean of type [edu.java.spring.ws.dao.UserDao] found for dependency
This means that there's no bean available to fulfill that dependency. Yes, you have an implementation of the interface, but you haven't created a bean for that implementation. You have two options:
UserDaoImpl
with @Component
or @Repository
, and let the component scan do the work for you, exactly as you have done with UserService
.UserBoImpl
.Remember that if you create the bean explicitly you need to put the definition before the component scan. In this case the order is important.
Applying the BoxCox transformation to data, without the need of any underlying model, can be done currently using the package geoR. Specifically, you can use the function boxcoxfit() for finding the best parameter and then predict the transformed variables using the function BCtransform().
I have written my own that you can use. This one works has sqlite, is thread safe and is in C++ for UNIX.
You should be able to pick it apart and use the C compatible code.

{
id = mo["ProcessorId"].ToString();
break;
}

To speed up this procedure, make sure you don't use SELECT *
, but only select what you really need. Use SELECT *
only during development when you try to find out what you need to use, because then the query will take much longer to complete.

In CSS3 paged media this is possible using position: running()
and content: element()
.
Example from the CSS Generated Content for Paged Media Module draft:
@top-center {
content: element(heading);
}
.runner {
position: running(heading);
}
.runner can be any element and heading
is an arbitrary name for the slot.
EDIT: to clarify, there is basically no browser support so this was mostly meant to be for future reference/in addition to the 'practical answers' given already.
There is another (faster?) way to find where your app data is without Terminal:
If you are fortunate enough to be running Python 3.4+, you can use pathlib
:
from pathlib import Path
path = Path(dir, subdir, filename) # returns a path of the system's path flavour
or, equivalently,
path = Path(dir) / subdir / filename
Error 127
means one of two things:
$PATH
, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.file -L
on /bin/sh
(to get your default/native format) and on the compiler itself (to see what format it is).if the problem is (2), then you can solve it in a few diff ways:
If you'd like to initialize the array to values other than 0, with gcc
you can do:
int array[1024] = { [ 0 ... 1023 ] = -1 };
This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99
to compile your code.
Sol-1:
select
StartTime
, EndTime
, CONVERT(NVARCHAR,(EndTime-StartTime), 108) as TimeDiff
from
[YourTable]
Sol-2:
select
StartTime
, EndTime
, DATEDIFF(hh, StartTime, EndTime)
, DATEDIFF(mi, StartTime, EndTime) % 60
from
[YourTable]
Sol-3:
select
DATEPART(hour,[EndTime]-[StartTime])
, DATEPART(minute,[EndTime]-[StartTime])
from

Datepart works the best
Ctrl-w followed by H, J, K or L (capital) will move the current window to the far left
, bottom
, top
or right
respectively like normal cursor navigation.
The lower case equivalents move focus instead of moving the window.
Some time ago I have made a small lib find-and
, which is available on npm, for working with nested objects in a lodash manner. There's the returnFound
function which returns the found object, or an object array if there's more than one object found.
E.g.,
const findAnd = require('find-and');
const a = [
{
'title': "some title",
'channel_id':'123we',
'options': [
{
'channel_id':'abc',
'image':'http://asdasd.com/all-inclusive-block-img.jpg',
'title':'All-Inclusive',
'options':[
{
'channel_id':'dsa2',
'title':'Some Recommends',
'options':[
{
'image':'http://www.asdasd.com',
'title':'Sandals',
'id':'1',
'content':{},
},
],
},
],
},
],
},
];
findAnd.returnFound(a, {id: '1'});
returns
{
'image':'http://www.asdasd.com',
'title':'Sandals',
'id':'1',
'content':{},
}
You can use php in the style sheet. Just remember to set header("Content-type: text/css") in the style.php (or whatever then name is) file
With most .net unit testing frameworks you can put an [ExpectedException] attribute on the test method. However this can't tell you that the exception happened at the point you expected it to. That's where xunit.net can help.
With xunit you have Assert.Throws, so you can do things like this:
[Fact]
public void CantDecrementBasketLineQuantityBelowZero()
{
var o = new Basket();
var p = new Product {Id = 1, NetPrice = 23.45m};
o.AddProduct(p, 1);
Assert.Throws<BusinessException>(() => o.SetProductQuantity(p, -3));
}
[Fact] is the xunit equivalent of [TestMethod]
Seems based on benchmarks at JSPerf that using +=
is the fastest method, though not necessarily in every browser.
For building strings in the DOM, it seems to be better to concatenate the string first and then add to the DOM, rather then iteratively add it to the dom. You should benchmark your own case though.
(Thanks @zAlbee for correction)
Try this query.. It uses the Analytic function SUM:
SELECT * FROM
(
SELECT SUM(1) OVER(PARTITION BY ctn_no) cnt, A.*
FROM table1 a
WHERE s_ind ='Y'
)
WHERE cnt > 2
Am not sure why you are identifying a record as a duplicate if the ctn_no repeats more than 2 times. FOr me it repeats more than once it is a duplicate. In this case change the las part of the query to WHERE cnt > 1
ant-contrib is evil; write a custom ant task.
ant-contrib is evil because it tries to convert ant from a declarative style to an imperative style. But xml makes a crap programming language.
By contrast a custom ant task allows you to write in a real language (Java), with a real IDE, where you can write unit tests to make sure you have the behavior you want, and then make a clean declaration in your build script about the behavior you want.
This rant only matters if you care about writing maintainable ant scripts. If you don't care about maintainability by all means do whatever works. :)

After many false starts and dead ends, I'm finally able to deploy website code with just "git push remote" thanks to this article.
The author's post-update script is only one line long and his solution doesn't require .htaccess configuration to hide the Git repo as some others do.
A couple of stumbling blocks if you're deploying this on an Amazon EC2 instance;
1) If you use sudo to create the bare destination repository, you have to change the owner of the repo to ec2-user or the push will fail. (Try "chown ec2-user:ec2-user repo.")
2) The push will fail if you don't pre-configure the location of your amazon-private-key.pem, either in /etc/ssh/ssh_config as an IdentityFile parameter or in ~/.ssh/config using the "[Host] - HostName - IdentityFile - User" layout described here...
...HOWEVER if Host is configured in ~/.ssh/config and different than HostName the Git push will fail. (That's probably a Git bug)
You need
@ManagedBean(name="userBean")
Make sure you have getUser()

Make sure that User

at the end with echo
Explanation:
I've found that (at Chrome 56, OSX) the favicon state appears to be cached for the browser lifetime, so if a favicon isn't being loaded, it won't be until after restarting Chrome. It appears that it doesn't show up in the "application" tab in dev tools and isn't cleared by a hard reload or 'Clear site data'.
The old school way ;)
public static void openit(string x) {
System.Diagnostics.Process.Start("cmd", "/C start" + " " + x);
}
Use: openit("www.google.com");
Two important pitfalls
which were ignored by other answers so far:
Trailing newline removal from command expansion
This is a problem for the:
value="$(cat config.txt)"
type solutions, but not for read
based solutions.
Command expansion removes trailing newlines:
S="$(printf "a\n")"
printf "$S" | od -tx1
Outputs:
0000000 61
0000001
This breaks the naive method of reading from files:
FILE="$(mktemp)"
printf "a\n\n" > "$FILE"
S="$(<"$FILE")"
printf "$S" | od -tx1
rm "$FILE"
POSIX workaround: append an extra char to the command expansion and remove it later:
S="$(cat $FILE; printf a)"
S="${S%a}"
printf "$S" | od -tx1
Outputs:
0000000 61 0a 0a
0000003
Almost POSIX workaround: ASCII encode. See below.
NUL character removal
There is no sane Bash way to store NUL characters in variables.
This affects both expansion and read
solutions, and I don't know any good workaround for it.
Example:
printf "a\0b" | od -tx1
S="$(printf "a\0b")"
printf "$S" | od -tx1
Outputs:
0000000 61 00 62
0000003
0000000 61 62
0000002
Ha, our NUL is gone!
Workarounds:
ASCII encode. See below.
use bash extension $""
literals:
S=$"a\0b"
printf "$S" | od -tx1
Only works for literals, so not useful for reading from files.
Workaround for the pitfalls
Store an uuencode base64 encoded version of the file in the variable, and decode before every usage:
FILE="$(mktemp)"
printf "a\0\n" > "$FILE"
S="$(uuencode -m "$FILE" /dev/stdout)"
uudecode -o /dev/stdout <(printf "$S") | od -tx1
rm "$FILE"
Output:
0000000 61 00 0a
0000003
uuencode and udecode are POSIX 7 but not in Ubuntu 12.04 by default (sharutils
package)... I don't see a POSIX 7 alternative for the bash process <()
substitution extension except writing to another file...
Of course, this is slow and inconvenient, so I guess the real answer is: don't use Bash if the input file may contain NUL characters.
I did all things necessary to add bundling to an MVC 3 web (I'm new to the existing solution). Styles.Render
didn't work for me. I finally discovered I was simply missing a colon. In a master page: <%: Styles.Render("~/Content/Css") %>
I'm still confused about why (on the same page) <% Html.RenderPartial("LogOnUserControl"); %>
works without the colon.

There are mentions of it in this post but no one explicitly addresses it, so maybe this will save people some time. If you are like me and have multiple classes extending one root class which extends ActionBarActivity, it may not be immediately obvious that trying to set that activity to a NoTitleBar/NoActionBar will throw an error, specifically:
"You need to use a Theme.AppCompat theme (or descendant) with this activity"
You can fix this changing the extends to Activity.
Just to add to the other answers: In case you don't like the onload
callback approach, you can "promisify" it like so:

Another option is to use the cor.test function, instead of lm:
> x <- c(44.4, 45.9, 41.9, 53.3, 44.7, 44.1, 50.7, 45.2, 60.1)
> y <- c( 2.6, 3.1, 2.5, 5.0, 3.6, 4.0, 5.2, 2.8, 3.8)
> mycor = cor.test(x,y)
> mylm = lm(x~y)
# r and rsquared:
> cor.test(x,y)$estimate ** 2
cor
0.3262484
> summary(lm(x~y))$r.squared
[1] 0.3262484
# P.value
> lmp(lm(x~y)) # Using the lmp function defined in Chase's answer
[1] 0.1081731
> cor.test(x,y)$p.value
[1] 0.1081731
For anyone looking for the short versions:
var memoryStream = new MemoryStream(File.ReadAllBytes("1.dat"));
File.WriteAllBytes("1.dat", memoryStream.ToArray());
This query will use index if you have it for signup_date
field
SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d')
FROM users
WHERE signup_date >= CURDATE() && signup_date < (CURDATE() + INTERVAL 1 DAY)
This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:
SELECT
s.Name AS SchemaName,
t.NAME AS TableName,
p.rows AS RowCounts,
SUM(a.total_pages) * 8 AS TotalSpaceKB,
SUM(a.used_pages) * 8 AS UsedSpaceKB,
(SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM
sys.tables t
INNER JOIN
sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN
sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN
sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN
sys.allocation_units a ON p.partition_id = a.container_id
WHERE
t.NAME NOT LIKE 'dt%' -- filter out system tables for diagramming
AND t.is_ms_shipped = 0
AND i.OBJECT_ID > 255
GROUP BY
t.Name, s.Name, p.Rows
ORDER BY
s.Name, t.Name
If you want to separate table space from index space, you need to use AND i.index_id IN (0,1)
for the table space (index_id = 0
is the heap space, index_id = 1
is the size of the clustered index = data pages) and AND i.index_id > 1
for the index-only space
With the upcoming release of iOS 7 you will notice that the "standard" icon radius has been increased. So try to do what Apple and I suggested with this answer.
It appears that for a 120px icon the formula that best represents its shape on iOS 7 is the following superellipse:
|x/120|^5 + |y/120|^5 = 1
Obviously you can change the 120
number with the desired icon size to get the corresponding function.
Original
You should provide an image that has 90° corners (it’s important to avoid cropping the corners of your icon—iOS does that for you when it applies the corner-rounding mask) (Apple Documentation)
The best approach is not rounding the corners of your icons at all. If you set your icon as a square icon, iOS will automatically overlay the icon with a predefined mask that will set the appropriate rounded corners.
If you manually set rounded corners for your icons, they will probably look broken in this or that device, because the rounding mask happens to slightly change from an iOS version to another. Sometimes your icons will be slightly larger, sometimes (sigh) slightly smaller. Using a square icon will free you from this burden, and you will be sure to have an always up-to-date and good looking icon for your app.
This approach is valid for each icon size (iPhone/iPod/iPad/retina), and also for the iTunes artwork. I followed this approach a couple of times, and if you want I can post you a link to an app that uses native square icons.
Edit
To better understand this answer, please refer to the official Apple documentation about iOS icons. In this page it is clearly stated that a square icon will automatically get these things when displayed on an iOS device:
So, you can achieve whatever effect you want just drawing a plain square icon and filling content in it. The final corner radius will be something similar to what the other answers here are saying, but this will never be guaranteed, since those numbers are not part of the official Apple documentation on iOS. They ask you to draw square icons, so ... why not?
As explained above by @kris, depending on the region configurations of MS Excel it won't interpret the comma as the separator character. In my case I had to change it to semi-colon
The window.navigator.platform property is not spoofed when the userAgent string is changed. I tested on my Mac if I change the userAgent to iPhone or Chrome Windows, navigator.platform remains MacIntel.
The property is also read-only
I could came up with the following table
Mac Computers
Mac68K
Macintosh 68K system.
MacPPC
Macintosh PowerPC system.
MacIntel
Macintosh Intel system.iOS Devices
iPhone
iPhone.
iPod
iPod Touch.
iPad

Modern macs returns navigator.platform == "MacIntel"
but to give some "future proof" don't use exact matching, hopefully they will change to something like MacARM
or MacQuantum
in future.
var isMac = navigator.platform.toUpperCase().indexOf('MAC')>=0;

Look here for the answer by TheMattster. I implemented it and it worked like a charm. In a nutshell, his solution suggests to add the COM dll as a resource to the project (so now it compiles into the project's dll), and upon the first run write it to a file (i.e. the dll file I wanted there in the first place).
The following is taken from his answer.
Step 1) Add the DLL as a resource (below as "Resources.DllFile"). To do this open project properties, select the resources tab, select "add existing file" and add the DLL as a resource.
Step 2) Add the name of the DLL as a string resource (below as "Resources.DllName").
Step 3) Add this code to your main form-load:
if (!File.Exists(Properties.Resources.DllName))
{
var outStream = new StreamWriter(Properties.Resources.DllName, false);
var binStream = new BinaryWriter(outStream.BaseStream);
binStream.Write(Properties.Resources.DllFile);
binStream.Close();
}
My problem was that not only I had to use the COM dll in my project, I also had to deploy it with my app using ClickOnce, and without being able to add reference to it in my project the above solution is practically the only one that worked.
As I know jsPDF is not working with CSS and the same issue I was facing.
To solve this issue, I used Html2Canvas. Just Add HTML2Canvas JS and then use pdf.addHTML()
instead of pdf.fromHTML()
.
Here's my code (no other code):
var pdf = new jsPDF('p', 'pt', 'letter');
pdf.addHTML($('#ElementYouWantToConvertToPdf')[0], function () {
pdf.save('Test.pdf');
});
Best of Luck!
Edit: Refer to this line in case you didn't find .addHTML()

Just happened to me after upgrading to Android Studio 3.1. The Offline Work checkbox was unchecked, so no luck there.

If you want it to display the content of the file live, and update when the file is altered, just use this script:
@echo off
:start
cls
type myfile.txt
goto start
That will repeat forever until you close the cmd window.
In My case, I am running a local Django backend in IP 127.0.0.1:8000

I prefer the first version to start a java application just because it has less pitfalls ("welcome to classpath hell"). The second one requires an executable jar file and the classpath for that application has to be defined inside the jar's manifest (all other classpath declaration will be silently ignored...). So with the second version you'd have to look into the jar, read the manifest and try to find out if the classpath entries are valid from where the jar is stored... That's avoidable.
I don't expect any performance advantages or disadvantages for either version. It's just telling the jvm which class to use for the main thread and where it can find the libraries.
Either attribute can be applied to View's (visual control) horizontal or vertical size. It's used to set a View or Layouts size based on either it's contents or the size of it's parent layout rather than explicitly specifying a dimension.
fill_parent
(deprecated and renamed MATCH_PARENT
in API Level 8 and higher)
Setting the layout of a widget to fill_parent will force it to expand to take up as much space as is available within the layout element it's been placed in. It's roughly equivalent of setting the dockstyle of a Windows Form Control to Fill
.
Setting a top level layout or control to fill_parent will force it to take up the whole screen.
wrap_content
Setting a View's size to wrap_content will force it to expand only far enough to contain the values (or child controls) it contains. For controls -- like text boxes (TextView) or images (ImageView) -- this will wrap the text or image being shown. For layout elements it will resize the layout to fit the controls / layouts added as its children.
It's roughly the equivalent of setting a Windows Form Control's Autosize
property to True.

I know this is a rather old post but I have another slightly simpler solution. You could create another class within and make it abstract. Next make an Abstract method name it whatever you like. In the original class make a method that takes the new class as a parameter, in this method call the abstract method. It will look something like this.
public class Demo {
public Demo(/.../){
}
public void view(Action a){
a.preform();
}
/**
* The Action Class is for making the Demo
* View Custom Code
*/
public abstract class Action {
public Action(/.../){
}
abstract void preform();
}
}
Now you can do something like this to call a method from within the class.
/...
Demo d = new Demo;
Action a = new Action() {
@Override
void preform() {
//Custom Method Code Goes Here
}
};
/.../
d.view(a)
Like I said I know its old but this way I think is a little easier. Hope it helps.
in my problem I want the text of anchor <a>text</a>
inside my view to be based on some value
and that text is retrieved form App string Resources
so, this @()
is the solution
<a href='#'>
@(Model.ID == 0 ? Resource_en.Back : Resource_en.Department_View_DescartChanges)
</a>
if the text is not from App string Resources
use this
@(Model.ID == 0 ? "Back" :"Descart Changes")
In Excel, the substring function is called MID function, and indexOf is called FIND for case-sensitive location and SEARCH function for non-case-sensitive location. For the first portion of your text parsing the LEFT function may also be useful.
See all the text functions here: Text Functions (reference).

Based on @chris-dolphin 's answer but using helper function:
// Creates svg element, returned as jQuery object
function $s(elem) {
return $(document.createElementNS('http://www.w3.org/2000/svg', elem));
}
var $svg = $s("svg");
var $circle = $s("circle").attr({...});
$svg.append($circle);
Use an array for this.
var markers = [];
for (var i = 0; i < coords.length; ++i) {
markers[i] = "some stuff";
}
Int32.parse(string)--->
Int32.Parse (string s) method converts the string representation of a number to its 32-bit signed integer equivalent. When s is a null reference, it will throw ArgumentNullException. If s is other than integer value, it will throw FormatException. When s represents a number less than MinValue or greater than MaxValue, it will throw OverflowException. For example:
string s1 = "1234";
string s2 = "1234.65";
string s3 = null;
string s4 = "123456789123456789123456789123456789123456789";
result = Int32.Parse(s1); //1234
result = Int32.Parse(s2); //FormatException
result = Int32.Parse(s3); //ArgumentNullException
result = Int32.Parse(s4); //OverflowException
Convert.ToInt32(string) --> Convert.ToInt32(string s) method converts the specified string representation of 32-bit signed integer equivalent. This calls in turn Int32.Parse () method. When s is a null reference, it will return 0 rather than throw ArgumentNullException. If s is other than integer value, it will throw FormatException. When s represents a number less than MinValue or greater than MaxValue, it will throw OverflowException.
For example:
result = Convert.ToInt32(s1); // 1234
result = Convert.ToInt32(s2); // FormatException
result = Convert.ToInt32(s3); // 0
result = Convert.ToInt32(s4); // OverflowException
iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.
Python 3 handles strings a bit different. Originally there was just one type for
strings: str
. When unicode gained traction in the '90s the new unicode
type
was added to handle Unicode without breaking pre-existing code1. This is
effectively the same as str
but with multibyte support.
In Python 3 there are two different types:
bytes
type. This is just a sequence of bytes, Python doesn't know
anything about how to interpret this as characters.str
type. This is also a sequence of bytes, but Python knows how to
interpret those bytes as characters.unicode
type was dropped. str
now supports unicode.In Python 2 implicitly assuming an encoding could cause a lot of problems; you
could end up using the wrong encoding, or the data may not have an encoding at
all (e.g. it’s a PNG image).
Explicitly telling Python which encoding to use (or explicitly telling it to
guess) is often a lot better and much more in line with the "Python philosophy"
of "explicit is better than implicit".
This change is incompatible with Python 2 as many return values have changed,
leading to subtle problems like this one; it's probably the main reason why
Python 3 adoption has been so slow. Since Python doesn't have static typing2
it's impossible to change this automatically with a script (such as the bundled
2to3
).
str
to bytes
with bytes('h€llo', 'utf-8')
; this should
produce b'H\xe2\x82\xacllo'
. Note how one character was converted to three
bytes.bytes
to str
with b'H\xe2\x82\xacllo'.decode('utf-8')
.Of course, UTF-8 may not be the correct character set in your case, so be sure to use the correct one.
In your specific piece of code, nextline
is of type bytes
, not str
,
reading stdout
and stdin
from subprocess
changed in Python 3 from str
to
bytes
. This is because Python can't be sure which encoding this uses. It
probably uses the same as sys.stdin.encoding
(the encoding of your system),
but it can't be sure.
You need to replace:
sys.stdout.write(nextline)
with:
sys.stdout.write(nextline.decode('utf-8'))
or maybe:
sys.stdout.write(nextline.decode(sys.stdout.encoding))
You will also need to modify if nextline == ''
to if nextline == b''
since:
>>> '' == b''
False
Also see the Python 3 ChangeLog, PEP 358, and PEP 3112.
1 There are some neat tricks you can do with ASCII that you can't do with multibyte character sets; the most famous example is the "xor with space to switch case" (e.g. chr(ord('a') ^ ord(' ')) == 'A'
) and "set 6th bit to make a control character" (e.g. ord('\t') + ord('@') == ord('I')
). ASCII was designed in a time when manipulating individual bits was an operation with a non-negligible performance impact.
2 Yes, you can use function annotations, but it's a comparatively new feature and little used.
After closing and reopening VS, this should resolve.
This is how I configure it on my server:

The server (that the POST request is sent to) needs to include the Content-Type header in its response.
Here's a list of typical headers to include, including one custom "X_ACCESS_TOKEN" header:
"X-ACCESS_TOKEN", "Access-Control-Allow-Origin", "Authorization", "Origin", "x-requested-with", "Content-Type", "Content-Range", "Content-Disposition", "Content-Description"
That's what your http server guy needs to configure for the web server that you're sending your requests to.
You may also want to ask your server guy to expose the "Content-Length" header.
He'll recognize this as a Cross-Origin Resource Sharing (CORS) request and should understand the implications of making those server configurations.

if len(driver.find_elements_by_id('blah')) > 0: #pay attention: find_element*s*

They would start by hiding the defining a structure that would hold members necessary for the implementation. Then providing a group of functions that would manipulate the contents of the structure.
Something like this:
typedef struct vec
{
unsigned char* _mem;
unsigned long _elems;
unsigned long _elemsize;
unsigned long _capelems;
unsigned long _reserve;
};
vec* vec_new(unsigned long elemsize)
{
vec* pvec = (vec*)malloc(sizeof(vec));
pvec->_reserve = 10;
pvec->_capelems = pvec->_reserve;
pvec->_elemsize = elemsize;
pvec->_elems = 0;
pvec->_mem = (unsigned char*)malloc(pvec->_capelems * pvec->_elemsize);
return pvec;
}
void vec_delete(vec* pvec)
{
free(pvec->_mem);
free(pvec);
}
void vec_grow(vec* pvec)
{
unsigned char* mem = (unsigned char*)malloc((pvec->_capelems + pvec->_reserve) * pvec->_elemsize);
memcpy(mem, pvec->_mem, pvec->_elems * pvec->_elemsize);
free(pvec->_mem);
pvec->_mem = mem;
pvec->_capelems += pvec->_reserve;
}
void vec_push_back(vec* pvec, void* data, unsigned long elemsize)
{
assert(elemsize == pvec->_elemsize);
if (pvec->_elems == pvec->_capelems) {
vec_grow(pvec);
}
memcpy(pvec->_mem + (pvec->_elems * pvec->_elemsize), (unsigned char*)data, pvec->_elemsize);
pvec->_elems++;
}
unsigned long vec_length(vec* pvec)
{
return pvec->_elems;
}
void* vec_get(vec* pvec, unsigned long index)
{
assert(index < pvec->_elems);
return (void*)(pvec->_mem + (index * pvec->_elemsize));
}
void vec_copy_item(vec* pvec, void* dest, unsigned long index)
{
memcpy(dest, vec_get(pvec, index), pvec->_elemsize);
}
void playwithvec()
{
vec* pvec = vec_new(sizeof(int));
for (int val = 0; val < 1000; val += 10) {
vec_push_back(pvec, &val, sizeof(val));
}
for (unsigned long index = (int)vec_length(pvec) - 1; (int)index >= 0; index--) {
int val;
vec_copy_item(pvec, &val, index);
printf("vec(%d) = %d\n", index, val);
}
vec_delete(pvec);
}
Further to this they would achieve encapsulation by using void* in the place of vec* for the function group, and actually hide the structure definition from the user by defining it within the C module containing the group of functions rather than the header. Also they would hide the functions that you would consider to be private, by leaving them out from the header and simply prototyping them only in the C module.
The full list is:
DB, DW, DD, DQ, DT, DDQ, and DO (used to declare initialized data in the output file.)
See: http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html
They can be invoked in a wide range of ways: (Note: for Visual-Studio - use "h" instead of "0x" syntax - eg: not 0x55 but 55h instead):
db 0x55 ; just the byte 0x55
db 0x55,0x56,0x57 ; three bytes in succession
db 'a',0x55 ; character constants are OK
db 'hello',13,10,'$' ; so are string constants
dw 0x1234 ; 0x34 0x12
dw 'A' ; 0x41 0x00 (it's just a number)

You need to store the psftp script (lines from open
to bye
) into a separate file and pass that to psftp
using -b
switch:
cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"
Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b
EDIT: For username+password: As you cannot use psftp
commands in a batch file, for the same reason, you cannot specify the username and the password as psftp
commands. These are inputs to the open
command. While you can specify the username with the open
command (open <user>@<IP>
), you cannot specify the password this way. This can be done on a psftp
command line only. Then it's probably cleaner to do all on the command-line:
cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>
And remove the open
, <user>
and <PW>
lines from your script.txt
.
Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw
What you are doing atm is that you run psftp
without any parameter or commands. Once you exit it (like by typing bye
), your batch file continues trying to run open
command (and others), what Windows shell obviously does not understand.
If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:
(
echo cd ...
echo lcd ...
echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>
I user for searching the size of motorcycle :
For example : Data = "Tire cycle size 70 / 90 - 16"
i can search with "70 90 16"
$searchTerms = preg_split("/[\s,-\/?!]+/", $itemName);
foreach ($searchTerms as $term) {
$term = trim($term);
if (!empty($term)) {
$searchTermBits[] = "name LIKE '%$term%'";
}
}
$query = "SELECT * FROM item WHERE " .implode(' AND ', $searchTermBits);
This solution maps / to commenting and ? to uncommenting (comment toggling using the single mapping is too complex to implement properly). It takes comment strings from VIM's builtin commentstring
option which is populated from files like /usr/share/vim/vim*/ftplugin/*.vim
if filetype plugin on
is declared.
filetype plugin on
autocmd FileType * let b:comment = split(&commentstring, '%s', 1)
autocmd FileType * execute "map <silent> <Leader>/ :normal 0i" . b:comment[0] . "<C-O>$" . b:comment[1] . "<C-O>0<CR>"
autocmd FileType * execute "map <silent> <Leader>? :normal $" . repeat('x', strlen(b:comment[1])) . "0" . strlen(b:comment[0]) . "x<CR>"
firstarray
and secondarray
are converted to a pointer to int, when passed to printarray()
.
printarray(int arg[], ...)
is equivalent to printarray(int *arg, ...)
However, this is not specific to C++. C has the same rules for passing array names to a function.
@Alex aw that's a bummer. What if in your iframe

Definitely a hack, but it might work for Firefox. Although I wonder if the load event would fire too soon in that case.

There's also a shorthand ternary operator and it looks like this:
(expression1) ?: expression2 will return expression1 if it evaluates to true or expression2 otherwise.
Example:
$a = 'Apples';
echo ($a ?: 'Oranges') . ' are great!';
will return
Apples are great!
Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.

Nothing to do just "Reset to Default" your firewall setting it will start working.
I read many solutions but nothing worked properly, so at last I reset firewall settings which worked.
Try this
#include <stdio.h>
struct context;
struct funcptrs{
void (*func0)(struct context *ctx);
void (*func1)(void);
};
struct context{
struct funcptrs fps;
};
void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }
void getContext(struct context *con){
con->fps.func0 = func0;
con->fps.func1 = func1;
}
int main(int argc, char *argv[]){
struct context c;
c.fps.func0 = func0;
c.fps.func1 = func1;
getContext(&c);
c.fps.func0(&c);
getchar();
return 0;
}
I have used jQuery AJAX to make AJAX requests.
Check the following code:

success: function(msg){
$('#output').append(msg);
}
});
});
});

If this is just a one-off exercise, as an easier alternative, you could apply filters to your source data, and then copy and paste the filtered rows into your new worksheet?
A very simple way is to add the image as a background to a DIV then load an empty transparent gif set to the same size as the DIV in the foreground. that keeps the less determined out. They cant get the background without viewing the code and copying the URL and right clicking just downloads the transparent gif.
The easiest way to for-each every char
in a String
is to use toCharArray()
:
for (char ch: "xyz".toCharArray()) {
}
This gives you the conciseness of for-each construct, but unfortunately String
(which is immutable) must perform a defensive copy to generate the char[]
(which is mutable), so there is some cost penalty.
From the documentation:
[
toCharArray()
returns] a newly allocated character array whose length is the length of this string and whose contents are initialized to contain the character sequence represented by this string.
There are more verbose ways of iterating over characters in an array (regular for loop, CharacterIterator
, etc) but if you're willing to pay the cost toCharArray()
for-each is the most concise.
I don't believe Eclipse has a JavaScript debugger - those breakpoints are for Java code (I'm guessing you are editing a JSP file?)
Use Firebug to debug Javascript code, it's an excellent add-on that all web developers should have in their toolbox.

There is no such thing as C# 3.5 - the cause of confusion here is that the C# 3.0 is present in .NET 3.5. The language and framework are versioned independently, however - as is the CLR, which is at version 2.0 for .NET 2.0 through 3.5, .NET 4 introducing CLR 4.0, service packs notwithstanding. The CLR in .NET 4.5 has various improvements, but the versioning is unclear: in some places it may be referred to as CLR 4.5 (this MSDN page used to refer to it that way, for example), but the Environment.Version
property still reports 4.0.xxx.
As of May 3, 2017, the C# Language Team created a history of C# versions and features on their GitHub repository: Features Added in C# Language Versions. There is also a page that tracks upcoming and recently implemented language features.

I ran into a similar situation where I had events binded to the mouseenter/mouseleave/click states of an element, yet on an iPhone, the user had to double click the element to first trigger the mouseenter event, then again to fire the click event.
I resolved this using a similar method as above, but I made use of the jQuery $.browser plugin (for jQuery 1.9>) and added a .trigger event to the mouseenter binding event, as follows:
// mouseenter event
$('.element').on( "mouseenter", function() {
// insert mouseenter events below
// double click fix for iOS and mouseenter events
if ($.browser.iphone || $.browser.ipad) $(this).trigger('click');
});
// mouseleave event
$('.element').on( "mouseleave", function() {
// insert mouseout events below
});
// onclick event
$('.element').on( "click", function() {
// insert click events below
});
The .trigger prevents the need to double click the element by firing the .click event handler upon mouseenter (or initial click) of the element when viewed on iPhones or iPads. Might not be the most elegant solution, but it works great in my case and utilizes a plugin that I already had in place, and required me to add a single line of code to get my existing events working under these devices.
You can get the jQuery $.browser plugin here: https://github.com/gabceb/jquery-browser-plugin
memset
requires you to import the header string.h
file. So just add the following header
#include <string.h>
...
Be careful, the solution proposed with $a = array_combine($a, $a);
will not work for numeric values.
I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384)
to be the keys as well as the values however PHP manual states:
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
So I solved it like this:
foreach($array as $key => $val) {
$new_array[$val]=$val;
}
@DSchmdit answer worked for me. I would like to add on that. So my requirement was to filter a file based on some configurations stored in the table. The file is first retrieved and collected as list of dtos. I receive the configurations from the db and store it as another list. This is how I made the filtering work with streams
List<FPRSDeferralModel> modelList = Files
.lines(Paths.get("src/main/resources/rootFiles/XXXXX.txt")).parallel().parallel()
.map(line -> {
FileModel fileModel= new FileModel();
line = line.trim();
if (line != null && !line.isEmpty()) {
System.out.println("line" + line);
fileModel.setPlanId(Long.parseLong(line.substring(0, 5)));
fileModel.setDivisionList(line.substring(15, 30));
fileModel.setRegionList(line.substring(31, 50));
Map<String, String> newMap = new HashedMap<>();
newMap.put("other", line.substring(51, 80));
fileModel.setOtherDetailsMap(newMap);
}
return fileModel;
}).collect(Collectors.toList());
for (FileModel model : modelList) {
System.out.println("model:" + model);
}
DbConfigModelList respList = populate();
System.out.println("after populate");
List<DbConfig> respModelList = respList.getFeedbackResponseList();
Predicate<FileModel> somePre = s -> respModelList.stream().anyMatch(respitem -> {
System.out.println("sinde respitem:"+respitem.getPrimaryConfig().getPlanId());
System.out.println("s.getPlanid()"+s.getPlanId());
System.out.println("s.getPlanId() == respitem.getPrimaryConfig().getPlanId():"+
(s.getPlanId().compareTo(respitem.getPrimaryConfig().getPlanId())));
return s.getPlanId().compareTo(respitem.getPrimaryConfig().getPlanId()) == 0
&& (s.getSsnId() != null);
});
final List<FileModel> finalList = modelList.stream().parallel().filter(somePre).collect(Collectors.toList());
finalList.stream().forEach(item -> {
System.out.println("filtered item is:"+item);
});
The details are in the implementation of filter predicates. This proves much more perfomant over iterating over loops and filtering out
You can insert into a varbinary(max) field using T-SQL within SQL Server Management Studio and in particular using the OPENROWSET commmand.
For example:
INSERT Production.ProductPhoto
(
ThumbnailPhoto,
ThumbnailPhotoFilePath,
LargePhoto,
LargePhotoFilePath
)
SELECT ThumbnailPhoto.*, null, null, N'tricycle_pink.gif'
FROM OPENROWSET
(BULK 'c:\images\tricycle.jpg', SINGLE_BLOB) ThumbnailPhoto
Take a look at the following documentation for a good example/walkthrough
Working With Large Value Types
Note that the file path in this case is relative to the targeted SQL server and not your client running this command.
I very often use classes, rather than functions, for my decorators. I was having some trouble with this because an object won't have all the same attributes that are expected of a function. For example, an object won't have the attribute __name__
. I had a specific issue with this that was pretty hard to trace where Django was reporting the error "object has no attribute '__name__
'". Unfortunately, for class-style decorators, I don't believe that @wrap will do the job. I have instead created a base decorator class like so:
class DecBase(object):
func = None
def __init__(self, func):
self.__func = func
def __getattribute__(self, name):
if name == "func":
return super(DecBase, self).__getattribute__(name)
return self.func.__getattribute__(name)
def __setattr__(self, name, value):
if name == "func":
return super(DecBase, self).__setattr__(name, value)
return self.func.__setattr__(name, value)
This class proxies all the attribute calls over to the function that is being decorated. So, you can now create a simple decorator that checks that 2 arguments are specified like so:
class process_login(DecBase):
def __call__(self, *args):
if len(args) != 2:
raise Exception("You can only specify two arguments")
return self.func(*args)
I had the same error message after running out of drive space. When I realized somehow the php file was corrupted, I copied the content and created a new file (I´m using Sublime Text for editing), and it solved my problem
WHERE AND SELECT Condition In Array Format Laravel
use DB;
$conditions = array(
array('email', '=', '[email protected]')
);
$selected = array('id','name','email','mobile','created');
$result = DB::table('users')->select($selected)->where($conditions)->get();
You can destroy all things that was created same way except little thing change. For controller,
rails d controller_name (d stands for destroy)
For Model
rails d model_name
you just put d(destroy)
instead of g(generate)
in your migration.
You can work out the columns that are only in one DataFrame and use this to select a subset of columns in the merge.
cols_to_use = df2.columns.difference(df.columns)
Then perform the merge (note this is an index object but it has a handy tolist()
method).
dfNew = merge(df, df2[cols_to_use], left_index=True, right_index=True, how='outer')
This will avoid any columns clashing in the merge.
In addition to other answers, I recomend this online opensource service jsonschema2pojo.org for quick generating Java classes from json or json schema for GSON, Jackson 1.x or Jackson 2.x. For example, if you have:
{
"pageInfo": {
"pageName": "abc",
"pagePic": "http://example.com/content.jpg"
}
"posts": [
{
"post_id": "123456789012_123456789012",
"actor_id": 1234567890,
"picOfPersonWhoPosted": "http://example.com/photo.jpg",
"nameOfPersonWhoPosted": "Jane Doe",
"message": "Sounds cool. Can't wait to see it!",
"likesCount": 2,
"comments": [],
"timeOfPost": 1234567890
}
]
}
The jsonschema2pojo.org for GSON generated:
@Generated("org.jsonschema2pojo")
public class Container {
@SerializedName("pageInfo")
@Expose
public PageInfo pageInfo;
@SerializedName("posts")
@Expose

Why would you bother? Load your CSV into Excel like this:
$csv = Join-Path $env:TEMP "process.csv"
$xls = Join-Path $env:TEMP "process.xlsx"
$xl = New-Object -COM "Excel.Application"
$xl.Visible = $true
$wb = $xl.Workbooks.OpenText($csv)
$wb.SaveAs($xls, 51)
You just need to make sure that the CSV export uses the delimiter defined in your regional settings. Override with -Delimiter
if need be.
Edit: A more general solution that should preserve the values from the CSV as plain text. Code for iterating over the CSV columns taken from here.
$csv = Join-Path $env:TEMP "input.csv"
$xls = Join-Path $env:TEMP "output.xlsx"
$xl = New-Object -COM "Excel.Application"
$xl.Visible = $true
$wb = $xl.Workbooks.Add()
$ws = $wb.Sheets.Item(1)
$ws.Cells.NumberFormat = "@"
$i = 1
Import-Csv $csv | ForEach-Object {
$j = 1
foreach ($prop in $_.PSObject.Properties) {
if ($i -eq 1) {
$ws.Cells.Item($i, $j++).Value = $prop.Name
} else {
$ws.Cells.Item($i, $j++).Value = $prop.Value
}
}
$i++
}
$wb.SaveAs($xls, 51)
$wb.Close()
$xl.Quit()
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($xl)
Obviously this second approach won't perform too well, because it's processing each cell individually.
>>> d = {'1': 'one', '3': 'three', '2': 'two', '5': 'five', '4': 'four'}

Out of curiosity, some comparative timing:

EDIT: And in case you wonder why... the reason is that each of the above returns a different type of object, which may or may not be well suited for lookup operations:

>>> type(d.values())
<type 'list'>

Because of the condition in while
, the loop might never break:
while (entry != null) {
// If entry never becomes null here, loop will never break.
}
Instead of the null
check there, you can try this:
ZipEntry entry = null;
while ((entry = zip.getNextEntry()) != null) {
// Rest of your code
}
You can only use just the name of the type (with its namespace, of course) if the type is in mscorlib
or the calling assembly. Otherwise, you've got to include the assembly name as well:
Type type = Type.GetType("Namespace.MyClass, MyAssembly");
If the assembly is strongly named, you've got to include all that information too. See the documentation for Type.GetType(string)
for more information.
Alternatively, if you have a reference to the assembly already (e.g. through a well-known type) you can use Assembly.GetType
:
Assembly asm = typeof(SomeKnownType).Assembly;
Type type = asm.GetType(namespaceQualifiedTypeName);
GraphQL query format was designed in order to allow:
However, according to GraphQL documentation, you may create fragments in order to make selection sets more reusable:
# Only most used selection properties
fragment UserDetails on User {
id,
username
}
Then you could query all user details by:
FetchUsers {
users() {
...UserDetails
}
}
You can also add additional fields alongside your fragment:
FetchUserById($id: ID!) {
users(id: $id) {
...UserDetails
count
}
}

In javascript a key value array is stored as an object. There are such things as arrays in javascript, but they are also somewhat considered objects still, check this guys answer - Why can I add named properties to an array as if it were an object?
Arrays are typically seen using square bracket syntax, and objects ("key=>value" arrays) using curly bracket syntax, though you can access and set object properties using square bracket syntax as Alexey Romanov has shown.
Arrays in javascript are typically used only with numeric, auto incremented keys, but javascript objects can hold named key value pairs, functions and even other objects as well.
Simple Array eg.
$(document).ready(function(){
var countries = ['Canada','Us','France','Italy'];
console.log('I am from '+countries[0]);
$.each(countries, function(key, value) {
console.log(key, value);
});
});
Output -
0 "Canada"
1 "Us"
2 "France"
3 "Italy"
We see above that we can loop a numerical array using the jQuery.each function and access info outside of the loop using square brackets with numerical keys.
Simple Object (json)
$(document).ready(function(){
var person = {
name: "James",
occupation: "programmer",
height: {
feet: 6,
inches: 1
},
}
console.log("My name is "+person.name+" and I am a "+person.height.feet+" ft "+person.height.inches+" "+person.occupation);
$.each(person, function(key, value) {
console.log(key, value);
});
});
Output -
My name is James and I am a 6 ft 1 programmer
name James
occupation programmer
height Object {feet: 6, inches: 1}
In a language like php this would be considered a multidimensional array with key value pairs, or an array within an array. I'm assuming because you asked about how to loop through a key value array you would want to know how to get an object (key=>value array) like the person object above to have, let's say, more than one person.
Well, now that we know javascript arrays are used typically for numeric indexing and objects more flexibly for associative indexing, we will use them together to create an array of objects that we can loop through, like so -
JSON array (array of objects) -
$(document).ready(function(){
var people = [
{
name: "James",
occupation: "programmer",
height: {
feet: 6,
inches: 1
}
}, {
name: "Peter",
occupation: "designer",
height: {
feet: 4,
inches: 10
}
}, {
name: "Joshua",
occupation: "CEO",
height: {
feet: 5,
inches: 11
}
}
];
console.log("My name is "+people[2].name+" and I am a "+people[2].height.feet+" ft "+people[2].height.inches+" "+people[2].occupation+"\n");
$.each(people, function(key, person) {
console.log("My name is "+person.name+" and I am a "+person.height.feet+" ft "+person.height.inches+" "+person.occupation+"\n");
});
});
Output -
My name is Joshua and I am a 5 ft 11 CEO
My name is James and I am a 6 ft 1 programmer
My name is Peter and I am a 4 ft 10 designer
My name is Joshua and I am a 5 ft 11 CEO
Note that outside the loop I have to use the square bracket syntax with a numeric key because this is now an numerically indexed array of objects, and of course inside the loop the numeric key is implied.
Simplest and best:
i = 0
while not there_is_reason_to_break(i):
# some code here
i += 1
It may be tempting to choose the closest analogy to the C code possible in Python:
from itertools import count
for i in count():
if thereIsAReasonToBreak(i):
break
But beware, modifying i
will not affect the flow of the loop as it would in C. Therefore, using a while
loop is actually a more appropriate choice for porting that C code to Python.
You test k = M
instead of k == M
.
Maybe it is what you want to do, in this case, write if (match == 0 && (k = M))
A minor addition to the answers already posted: object files not compiled to be position independent are relocatable; they contain relocation table entries.
These entries allow the loader (that bit of code that loads a program into memory) to rewrite the absolute addresses to adjust for the actual load address in the virtual address space.
An operating system will try to share a single copy of a "shared object library" loaded into memory with all the programs that are linked to that same shared object library.
Since the code address space (unlike sections of the data space) need not be contiguous, and because most programs that link to a specific library have a fairly fixed library dependency tree, this succeeds most of the time. In those rare cases where there is a discrepancy, yes, it may be necessary to have two or more copies of a shared object library in memory.
Obviously, any attempt to randomize the load address of a library between programs and/or program instances (so as to reduce the possibility of creating an exploitable pattern) will make such cases common, not rare, so where a system has enabled this capability, one should make every attempt to compile all shared object libraries to be position independent.
Since calls into these libraries from the body of the main program will also be made relocatable, this makes it much less likely that a shared library will have to be copied.
It's one end of a communication channel, so often this would be represented as the URL of a server or service.
Surprised to see no one mentioned more capable, interactive and easier to use alternatives.
Just two lines and you get:
interactivity,
smooth scale,
colors based on whole dataframe instead of individual columns,
column names & row indices on axes,
zooming in,
panning,
built-in one-click ability to save it as a PNG format,
auto-scaling,
comparison on hovering,
bubbles showing values so heatmap still looks good and you can see values wherever you want:
import plotly.express as px
fig = px.imshow(df.corr())
fig.show()
All the same functionality with a tad much hassle. But still worth it if you do not want to opt-in for plotly and still want all these things:
from bokeh.plotting import figure, show, output_notebook
from bokeh.models import ColumnDataSource, LinearColorMapper
from bokeh.transform import transform
output_notebook()
colors = ['#d7191c', '#fdae61', '#ffffbf', '#a6d96a', '#1a9641']
TOOLS = "hover,save,pan,box_zoom,reset,wheel_zoom"
data = df.corr().stack().rename("value").reset_index()
p = figure(x_range=list(df.columns), y_range=list(df.index), tools=TOOLS, toolbar_location='below',
tooltips=[('Row, Column', '@level_0 x @level_1'), ('value', '@value')], height = 500, width = 500)
p.rect(x="level_1", y="level_0", width=1, height=1,

fill_color={'field': 'value', 'transform': LinearColorMapper(palette=colors, low=data.value.min(), high=data.value.max())},

C# is a language, .NET is an application framework. The .NET libraries can run on the CLR and thus any language which can run on the CLR can also use the .NET libraries.
If you are familiar with Java, this is similar... Java is a language built on top of the JVM... though any of the pre-assembled Java libraries can be used by another language built on top of the JVM.
In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:
.ball {
animation: bounce 1s infinite alternate;
-webkit-animation: bounce 1s infinite alternate;
}
@keyframes bounce {
from {
margin-top: 0;
}
to {
margin-top: -15px;
}
}
It's really useful for ArgumentException
and its derivatives:
public string DoSomething(string input)
{
if(input == null)
{
throw new ArgumentNullException(nameof(input));
}
...
Now if someone refactors the name of the input
parameter the exception will be kept up to date too.
It is also useful in some places where previously reflection had to be used to get the names of properties or parameters.
In your example nameof(T)
gets the name of the type parameter - this can be useful too:
throw new ArgumentException(nameof(T), $"Type {typeof(T)} does not support this method.");
Another use of nameof
is for enums - usually if you want the string name of an enum you use .ToString()
:
enum MyEnum { ... FooBar = 7 ... }
Console.WriteLine(MyEnum.FooBar.ToString());
> "FooBar"
This is actually relatively slow as .Net holds the enum value (i.e. 7
) and finds the name at run time.
Instead use nameof
:
Console.WriteLine(nameof(MyEnum.FooBar))
> "FooBar"
Now .Net replaces the enum name with a string at compile time.
Yet another use is for things like INotifyPropertyChanged
and logging - in both cases you want the name of the member that you're calling to be passed to another method:
// Property with notify of change
public int Foo
{
get { return this.foo; }
set
{
this.foo = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(this.Foo));
}
}
Or...
// Write a log, audit or trace for the method called
void DoSomething(... params ...)
{
Log(nameof(DoSomething), "Message....");
}
The error tells you that there is an error but you don´t catch it. This is how you can catch it:
getAllPosts().then(response => {
console.log(response);
}).catch(e => {
console.log(e);
});
You can also just put a console.log(reponse)
at the beginning of your API callback function, there is definitely an error message from the Graph API in it.
More information: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch
Or with async/await:
//some async function
try {
let response = await getAllPosts();
} catch(e) {
console.log(e);
}
There's a rather crude way of doing this, but be careful because first, this relies on python interpreter process identifying themselves as python, and second, it has the concomitant effect of also killing any other processes identified by that name.
In short, you can kill all python interpreters by typing this into your shell (make sure you read the caveats above!):
ps aux | grep python | grep -v "grep python" | awk '{print $2}' | xargs kill -9
To break this down, this is how it works. The first bit, ps aux | grep python | grep -v "grep python"
, gets the list of all processes calling themselves python, with the grep -v making sure that the grep command you just ran isn't also included in the output. Next, we use awk to get the second column of the output, which has the process ID's. Finally, these processes are all (rather unceremoniously) killed by supplying each of them with kill -9
.
I made some extensions for easy enum usage. Maybe someone can use it...
public static class EnumExtensions
{
/// <summary>
/// Gets all items for an enum value.
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="value">The value.</param>
/// <returns></returns>

{
foreach (object item in Enum.GetValues(typeof(T)))
{
yield return (T)item;
}
}
/// <summary>

/// </example>
public static IEnumerable<T> GetAllSelectedItems<T>(this Enum value)
{
int valueAsInt = Convert.ToInt32(value, CultureInfo.InvariantCulture);
foreach (object item in Enum.GetValues(typeof(T)))
{
int itemAsInt = Convert.ToInt32(item, CultureInfo.InvariantCulture);
if (itemAsInt == (valueAsInt & itemAsInt))
{
yield return (T)item;
}
}
}
/// <summary>

public static bool Contains<T>(this Enum value, T request)
{
int valueAsInt = Convert.ToInt32(value, CultureInfo.InvariantCulture);
int requestAsInt = Convert.ToInt32(request, CultureInfo.InvariantCulture);
if (requestAsInt == (valueAsInt & requestAsInt))
{
return true;
}
return false;
}
}
The enum itself must be decorated with the FlagsAttribute:
[Flags]
public enum EnumExample
{
ValueA = 1,
ValueB = 2,
ValueC = 4,
ValueD = 8,
Combi = ValueA | ValueB
}

Example
find <path> -name *FileName*
From manual:
find -name pattern
Base of file name (the path with the leading directories removed) matches shell pattern pattern. Because the leading directories are removed, the file names considered for a match with -name will never include a slash, so "-name a/b" will never match anything (you probably need to use -path instead). The metacharacters ("*", "?", and "[]") match a "." at the start of the base name (this is a change in find- utils-4.2.2; see section STANDARDS CONFORMANCE below). To ignore a directory and the files under it, use -prune; see an example in the description of -path. Braces are not recognised as being special, despite the fact that some shells including Bash imbue braces with a special meaning in shell patterns. The filename matching is performed with the use of the fnmatch(3) library function. Don't forget to enclose the pattern in quotes in order to protect it from expansion by the shell.
There is a lot of confusion about Repositories and Projects. In the past both terms were used pretty much interchangeably by the users and the GitHub's very own documentation. This is reflected by some of the answers and comments here that explain the subtle differences between those terms and when the one was preferred over the other. The difference were always subtle, e.g. like the issue tracker being part of the project but not part of the repository which might be thought of as a strictly git thing etc.
Currently repos and projects refer to a different kinds of entities that have separate APIs:
Since then it is no longer correct to call the repo a project or vice versa. Note that it is often confused in the official documentation and it is unfortunate that a term that was already widely used has been chosen as the name of the new entity but this is the case and we have to live with that.
The consequence is that repos and projects are usually confused and every time you read about GitHub projects you have to wonder if it's really about the projects or about repos. Had they chosen some other name or an abbreviation like "proj" then we could know that what is discussed is the new type of entity, a precise object with concrete properties, or a general speaking repo-like projectish kind of thingy.
The term that is usually unambiguous is "project board".
The first endpoint in the documentation of the Projects API:
is described as: List repository projects. It means that a repository can have many projects. So those two cannot mean the same thing. It includes Response if projects are disabled:
{
"message": "Projects are disabled for this repo",
"documentation_url": "https://developer.github.com/v3"
}
which means that some repos can have projects disabled. Again, those cannot be the same thing when a repo can have projects disabled.
There are some other interesting endpoints:
POST /repos/:owner/:repo/projects
POST /orgs/:org/projects
but there is no:
POST /users/:user/projects
Which leads us to another difference:
1. Repositories can belong to users or organizations
2. Projects can belong to repositories or organizations
or, more importantly:
1. Projects can belong to repositories but not the other way around
2. Projects can belong to organizations but not to users
3. Repositories can belong to organizations and to users

I know it's confusing. I tried to explain it as precisely as I could.
The recommended way is to create your own component, such as MyAppText. MyAppText would be a simple component that renders a Text component using your universal style and can pass through other props, etc.

Copying a folder or file from a server with a port defined to another server or local machine
scp -r -P port user@IP_address:/home/file/pathDirectory .
**Note:** The last . on the command directs it to copy everything in that folder to your directory of preference
For Excel POI:
sheetName.autoSizeColumn(cellnum);
You also have CSS Grid and CSS Flex, both can give you columns that keep their position and size ratios depending on screen size, and flex can also easily rearrange the columns if screen size is too small so they can maintain a minimum width nicely.
See these guides for full details:
Grid:
.container {
display: grid | inline-grid;
}
Flex:
.container {

You can already do this with module-level variables. Modules are the same no matter what module they're being imported from. So you can make the variable a module-level variable in whatever module it makes sense to put it in, and access it or assign to it from other modules. It would be better to call a function to set the variable's value, or to make it a property of some singleton object. That way if you end up needing to run some code when the variable's changed, you can do so without breaking your module's external interface.
It's not usually a great way to do things — using globals seldom is — but I think this is the cleanest way to do it.
You likely need to re-start VNC on both ends. i.e. when you say "restarted VNC", you probably just mean the client. But what about the other end? You likely need to re-start that end too. The root cause is likely a conflict. Many apps spy on the clipboard when they shouldn't. And many apps are not forgiving when they go to open the clipboard and can't. Robust ones will retry, others will simply not anticipate a failure and then they get fouled up and need to be restarted. Could be VNC, or it could be another app that's "listening" to the clipboard viewer chain, where it is obligated to pass along notifications to the other apps in the chain. If the notifications aren't sent, then VNC may not even know that there has been a clipboard update.
Use String.equalsIgnoreCase()
.
Use the Java API reference to find answers like these:
This page has a table of string constants including vbCrLf
vbCrLf
| Chr(13) & Chr(10) | Carriage return–linefeed combination
The first parameter is the String to encode; the second is the name of the character encoding to use (e.g., UTF-8).
Maybe try something like:
import matplotlib.pyplot as plt
import numpy
from scipy import stats
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = stats.kde.gaussian_kde(data)
x = numpy.arange(0., 8, .1)
plt.plot(x, density(x))
plt.show()
You can easily replace gaussian_kde()
by a different kernel density estimate.
There is a builtin function all
:
all (x > limit for x in my_list)
Being limit the value greater than which all numbers must be.
You are not changing the value of line. It should be something like this.
import java.io.BufferedReader;
import java.io.FileReader;
public class InsertValuesIntoTestDb {
@SuppressWarnings("rawtypes")
public static void main(String[] args) throws Exception {
String splitBy = ",";
BufferedReader br = new BufferedReader(new FileReader("test.csv"));
while((line = br.readLine()) != null){
String[] b = line.split(splitBy);
System.out.println(b[0]);
}
br.close();
}
}
readLine returns each line and only returns null when there is nothing left. The above code sets line and then checks if it is null.
There's a nice article with code on this topic on MSDN. I'm assuming that setting the Style property to ProgressBarStyle.Marquee is not appropriate (or is that what you are trying to control?? -- I don't think it is possible to stop/start this animation although you can control the speed as @Paul indicates).

ALTER TABLE table_name MODIFY column_name new_column_datatype [constraints]
CHANGE
.MODIFY
. You cannot change the name of the column using this statement.Hope, I explained well in detail.
It's just that you already have an object with Object.new
but you still don't have an object when using the constructor syntax.
Create a function that addresses all the whitespace possibilites and enable only those that seem appropriate:
SELECT dbo.ShowWhiteSpace(myfield) from mytable
Uncomment only those whitespace cases you want to test for:
CREATE FUNCTION dbo.ShowWhiteSpace (@str varchar(8000))
RETURNS varchar(8000)
AS
BEGIN
DECLARE @ShowWhiteSpace varchar(8000);
SET @ShowWhiteSpace = @str
SET @ShowWhiteSpace = REPLACE( @ShowWhiteSpace, CHAR(32), '[?]')
SET @ShowWhiteSpace = REPLACE( @ShowWhiteSpace, CHAR(13), '[CR]')

As a partial answer, here's a few points about colspan="0"
, which was mentioned in the question.
colspan="0"
doesn't work in any browser whatsoever. W3Schools is wrong (as usual). HTML 4 said that colspan="0"
should cause a column to span the whole table, but nobody implemented this and it was removed from the spec after HTML 4.
All major browsers treat it as equivalent to colspan="1"
.
Here's a demo showing this; try it on any browser you like.
td {_x000D_
border: 1px solid black;_x000D_
}
_x000D_
<table>_x000D_
<tr>_x000D_
<td>ay</td>_x000D_
<td>bee</td>_x000D_
<td>see</td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td colspan="0">colspan="0"</td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td colspan="1">colspan="1"</td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td colspan="3">colspan="3"</td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td colspan="1000">colspan="1000"</td>_x000D_
</tr>_x000D_
</table>
_x000D_
The HTML 4 spec (now old and outdated, but current back when this question was asked) did indeed say that colspan="0"
should be treated as spanning all columns:
The value zero ("0") means that the cell spans all columns from the current column to the last column of the column group (COLGROUP) in which the cell is defined.
However, most browsers never implemented this.
HTML 5.0 (made a candidate recommendation back in 2012), the WhatWG HTML living standard (the dominant standard today), and the latest W3 HTML 5 spec all do not contain the wording quoted from HTML 4 above, and unanimously agree that a colspan
of 0 is not allowed, with this wording which appears in all three specs:
The
td
andth
elements may have acolspan
content attribute specified, whose value must be a valid non-negative integer greater than zero ...
Sources:
The following claims from the W3Schools page linked to in the question are - at least nowadays - completely false:
Only Firefox supports colspan="0", which has a special meaning ... [It] tells the browser to span the cell to the last column of the column group (colgroup)
and
Differences Between HTML 4.01 and HTML5
NONE.
If you're not already aware that W3Schools is generally held in contempt by web developers for its frequent inaccuracies, consider this a lesson in why.

I think you need to run that .msi to install the dlls. After I ran that .msi I can go to (VS 2012) Add References > Assemblies > Extensions and all of the Microsoft.Office.Interop dlls are there.
On my computer the dlls are found in "c:\Program Files(x86)\Microsoft Visual Studio 12.0\Visual Studio Tools for Office\PIA" so you could check in a similar/equivalent directory on yours just to make sure they're not there?
Old Timer Favorite (it still works):
List<String> list;
for(int i = list.size() - 1; i >= 0; --i)
{
if(list.get(i).contains("bad"))
{
list.remove(i);
}
}
Benefits:
var $list = $('#divname input[id^="q17_"]'); // get all input controls with id q17_
// once you have $list you can do whatever you want
var ControlCnt = $list.length;
// Now loop through list of controls
$list.each( function() {
var id = $(this).prop("id"); // get id
var cbx = '';
if ($(this).is(':checkbox') || $(this).is(':radio')) {
// Need to see if this control is checked
}
else {
// Nope, not a checked control - so do something else
}
});
For the replacement portion, Python uses \1
the way sed and vi do, not $1
the way Perl, Java, and Javascript (amongst others) do. Furthermore, because \1
interpolates in regular strings as the character U+0001, you need to use a raw string or \escape it.

If you want to know if the object physically contains the property @gnarf's answer using hasOwnProperty
will do the work.
If you're want to know if the property exists anywhere, either on the object itself or up in the prototype chain, you can use the in
operator.
if ('prop' in obj) {
// ...
}
Eg.:
var obj = {};
'toString' in obj == true; // inherited from Object.prototype
obj.hasOwnProperty('toString') == false; // doesn't contains it physically
(Referring to Bootstrap 3), To hide the modal use: $('#modal').modal('hide')
. But the reason the backdrop hung around (for me) was because I was destroying the DOM for the modal before 'hide' finished.
To resolve this, I chained the hidden event with the DOM removal. In my case: this.render()
var $modal = $('#modal');
//when hidden
$modal.on('hidden.bs.modal', function(e) {
return this.render(); //DOM destroyer
});
$modal.modal('hide'); //start hiding
Here are two methods:
<script type="text/javascript">
var s="http://localhost/dms/mduserSecurity/UIL/index.php?menu=true&submenu
=true&pcode=1235";
var st=s.substring(0, s.indexOf("?"));
alert(st);
alert(s.replace(/\?.*/,''));
</script>
Or, you could try changing the parameter type to string, then convert the string to an integer in the method. I am new to MVC, but I believe you need nullable objects in your parameter list, how else will the controller indicate that no such parameter was provided? So...
public ActionResult ViewNextItem(string id)...
Your second version is less efficient because it creates an extra string object when there is simply no need to do so.
Immutability means that your first version behaves the way you expect and is thus the approach to be preferred.

I usually use the excellent Gucharmap to look up Unicode characters. It's installed on all recent Linux installations with Gnome under the name "Character Map". I don't know of any equivalent tools for Windows or Mac OS X, but its homepage lists a few.
First of all, both cases calls a constructor. If you write
Example *example = new Example();
then you are creating an object, call the constructor and retrieve a pointer to it.
If you write
Example example;
The only difference is that you are getting the object and not a pointer to it. The constructor called in this case is the same as above, the default (no argument) constructor.
As for the singleton question, you must simple invoke your static method by writing:
Example *e = Singleton::getExample();

The metacharacter \b
is an anchor like the caret and the dollar sign. It matches at a position that is called a "word boundary". This match is zero-length.
There are three different positions that qualify as word boundaries:
Simply put: \b
allows you to perform a "whole words only" search using a regular expression in the form of \bword\b
. A "word character" is a character that can be used to form words. All characters that are not "word characters" are "non-word characters".
In all flavors, the characters [a-zA-Z0-9_]
are word characters. These are also matched by the short-hand character class \w
. Flavors showing "ascii" for word boundaries in the flavor comparison recognize only these as word characters.
\w
stands for "word character", usually [A-Za-z0-9_]
. Notice the inclusion of the underscore and digits.
\B
is the negated version of \b
. \B
matches at every position where \b
does not. Effectively, \B
matches at any position between two word characters as well as at any position between two non-word characters.
\W
is short for [^\w]
, the negated version of \w
.
I tried so many solutions on here that didn't work for me, only displaying some of the ports. But the following displayed All of them and their information.
using (var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE Caption like '%(COM%'"))
{
var portnames = SerialPort.GetPortNames();
var ports = searcher.Get().Cast<ManagementBaseObject>().ToList().Select(p => p["Caption"].ToString());
var portList = portnames.Select(n => n + " - " + ports.FirstOrDefault(s => s.Contains(n))).ToList();
foreach(string s in portList)
{
Console.WriteLine(s);
}
}
}
This worked for me after i tryed many solutions:
For some reason the adb process didn't restart itself after installing new packages. Manualy killing adb.exe and attempt to import the project another time solved this problem for me.
Now try to run git commands on terminal.
It might ask you to do a two-step verification the first time, just follow the steps and you're done!
Easiest solution is to create the column using the correct data type: DATE
For example:
Create table:
create table test_date (mydate date);
Insert row:
insert into test_date values (to_date('01-01-2011','dd-mm-yyyy'));
To get the month and year, do as follows:
select to_char(mydate, 'MM-YYYY') from test_date;
Your result will be as follows: 01-2011
Another cool function to use is "EXTRACT"
select extract(year from mydate) from test_date;
This will return: 2011
Besides the box-shadow, transform and border options mentioned in other answers, WebKit browsers currently also obey -webkit-text-fill-color to set the colour of the "time elapsed" numbers, but since there is no way to set their background (which might vary with platform, e.g. inverted high-contrast modes on some operating systems), you would be advised to set -webkit-text-fill-color to the value "initial" if you've used it elsewhere and the audio element is inheriting this, otherwise some users might find those numbers unreadable.
Simple vba macro for opening utf-8 text and csv files
Sub OpenTextFile()
filetoopen = Application.GetOpenFilename("Text Files (*.txt;*.csv), *.txt;*.csv")
If filetoopen = Null Or filetoopen = Empty Then Exit Sub
Workbooks.OpenText Filename:=filetoopen, _
Origin:=65001, DataType:=xlDelimited, Comma:=True
End Sub
Origin:=65001 is UTF-8. Comma:True for .csv files distributed in colums

Try the JavaScript in operator.
if ('key' in myObj)
And the inverse.
if (!('key' in myObj))
Be careful! The in
operator matches all object keys, including those in the object's prototype chain.
Use myObj.hasOwnProperty('key')
to check an object's own keys and will only return true
if key
is available on myObj
directly:
myObj.hasOwnProperty('key')
Unless you have a specific reason to use the in
operator, using myObj.hasOwnProperty('key')
produces the result most code is looking for.

I think your return string data is very long. so the JSON format has been corrupted. You should change the max size for JSON data in this way :
Open the Web.Config file and paste these lines into the configuration section
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="50000000"/>
</webServices>
</scripting>
</system.web.extensions>
In Python3 I came up with type (f) == type (lambda x:x)
which yields True
if f
is a function and False
if it is not. But I think I prefer isinstance (f, types.FunctionType)
, which feels less ad hoc. I wanted to do type (f) is function
, but that doesn't work.

Recommendation:
when you have more than one condition with and
and or
is better separate with ()
to avoid verification problems
<c:if test="${(not validID) and (addressIso == 'US' or addressIso == 'BR')}">
Use sorted TreeMap
:
Map<String, Float> map = new TreeMap<>(yourMap);
It will automatically put entries sorted by keys. I think natural String
ordering will be fine in your case.
Note that HashMap
due to lookup optimizations does not preserve order.
