I found solution in this post: https://stackoverflow.com/questions/11883378/class-memcache-not-found-php#=
I found the working dll files for PHP 5.4.4
I don't knowhow stable they are but they work for sure. Credits goes to this link.

It is the 2.2.5.0 version, I noticed after compiling it (for PHP 5.4.4).
Please note that it is not 2.2.6 but works. I also mirrored them in my own FTP. Mirror links:

This is 2013. Forget about the 2009 comments. Likewise, if you are running serious traffic loads, do not even contemplate how to make-do with a windows based memcache. When dealing with a very large scale (500+ front end web servers) and 20+ back end database servers and replicants (mysql & mssql mix), a farm of memcached servers (12 servers in group) supports multiple high volume OLTP applications answering 25K ~ 40K mc->get calls per-second. These calls are those that do NOT have to reach a database.
IMHO, this use of memcached provided SERIOUS $$$,$$$savings on CAPEX for new DB servers & licences as well as on support contracts for large commercial designs.
Try this tag on the pages that use the ActiveX control:

Well I have successfully created my own working answer.

as well as
<script>
function phoneno(){

I am trying to detect the chrome and safari browser using jquery or javascript.
Use jQuery.browser
I thought we are not supposed to use jQuery.browser.
That's because detecting browsers is a bad idea. It is still the best way to detect the browser (when jQuery is involved) if you really intend to do that.
You can set href
attribute to javascript:void(0)
.disabled {_x000D_
/* Disabled link style */_x000D_
color: black;_x000D_
}
_x000D_
<a class="disabled" href="javascript:void(0)">LINK</a>

Avoid non-standard compiler extensions and implement it as a completely type-safe macro in pure standard C (ISO 9899:2011).
Solution
#define GENERIC_MAX(x, y) ((x) > (y) ? (x) : (y))
#define ENSURE_int(i) _Generic((i), int: (i))
#define ENSURE_float(f) _Generic((f), float: (f))
#define MAX(type, x, y) \
(type)GENERIC_MAX(ENSURE_##type(x), ENSURE_##type(y))
Usage
MAX(int, 2, 3)
Explanation
The macro MAX creates another macro based on the type
parameter. This control macro, if implemented for the given type, is used to check that both parameters are of the correct type. If the type
is not supported, there will be a compiler error.
If either x or y is not of the correct type, there will be a compiler error in the ENSURE_
macros. More such macros can be added if more types are supported. I've assumed that only arithmetic types (integers, floats, pointers etc) will be used and not structs or arrays etc.
If all types are correct, the GENERIC_MAX macro will be called. Extra parenthesis are needed around each macro parameter, as the usual standard precaution when writing C macros.
Then there's the usual problems with implicit type promotions in C. The ?:
operator balances the 2nd and 3rd operand against each other. For example, the result of GENERIC_MAX(my_char1, my_char2)
would be an int
. To prevent the macro from doing such potentially dangerous type promotions, a final type cast to the intended type was used.
Rationale
We want both parameters to the macro to be of the same type. If one of them is of a different type, the macro is no longer type safe, because an operator like ?:
will yield implicit type promotions. And because it does, we also always need to cast the final result back to the intended type as explained above.
A macro with just one parameter could have been written in a much simpler way. But with 2 or more parameters, there is a need to include an extra type parameter. Because something like this is unfortunately impossible:
// this won't work
#define MAX(x, y) \
_Generic((x), \
int: GENERIC_MAX(x, ENSURE_int(y)) \
float: GENERIC_MAX(x, ENSURE_float(y)) \
)
The problem is that if the above macro is called as MAX(1, 2)
with two int
, it will still try to macro-expand all possible scenarios of the _Generic
association list. So the ENSURE_float
macro will get expanded too, even though it isn't relevant for int
. And since that macro intentionally only contains the float
type, the code won't compile.
To solve this, I created the macro name during the pre-processor phase instead, with the ## operator, so that no macro gets accidentally expanded.
Examples
#include <stdio.h>
#define GENERIC_MAX(x, y) ((x) > (y) ? (x) : (y))
#define ENSURE_int(i) _Generic((i), int: (i))
#define ENSURE_float(f) _Generic((f), float: (f))
#define MAX(type, x, y) \
(type)GENERIC_MAX(ENSURE_##type(x), ENSURE_##type(y))
int main (void)
{
int ia = 1, ib = 2;
float fa = 3.0f, fb = 4.0f;
double da = 5.0, db = 6.0;
printf("%d\n", MAX(int, ia, ib)); // ok
printf("%f\n", MAX(float, fa, fb)); // ok
//printf("%d\n", MAX(int, ia, fa)); compiler error, one of the types is wrong
//printf("%f\n", MAX(float, fa, ib)); compiler error, one of the types is wrong
//printf("%f\n", MAX(double, fa, fb)); compiler error, the specified type is wrong
//printf("%f\n", MAX(float, da, db)); compiler error, one of the types is wrong
//printf("%d\n", MAX(unsigned int, ia, ib)); // wont get away with this either
//printf("%d\n", MAX(int32_t, ia, ib)); // wont get away with this either
return 0;
}
Actually what u did is also not wrong your declaration is right . With your declaration JVM will create a ArrayList of integer arrays i.e each entry in arraylist correspond to an integer array hence your add function should pass a integer array as a parameter.
For Ex:
list.add(new Integer[3]);
In this way first entry of ArrayList is an integer array which can hold at max 3 values.
Try this for multiple CSS styles:
$(this).css({
"background-color": 'red',
"color" : "white"
});
Another option,especially useful if you have many items you need to pivot is to let mysql build the query for you:
SELECT
GROUP_CONCAT(DISTINCT
CONCAT(
'ifnull(SUM(case when itemname = ''',
itemname,
''' then itemvalue end),0) AS `',
itemname, '`'
)
) INTO @sql
FROM
history;
SET @sql = CONCAT('SELECT hostid, ', @sql, '
FROM history
GROUP BY hostid');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
FIDDLE Added some extra values to see it working
GROUP_CONCAT
has a default value of 1000 so if you have a really big query change this parameter before running it
SET SESSION group_concat_max_len = 1000000;
Test:
DROP TABLE IF EXISTS history;
CREATE TABLE history
(hostid INT,
itemname VARCHAR(5),
itemvalue INT);
INSERT INTO history VALUES(1,'A',10),(1,'B',3),(2,'A',9),
(2,'C',40),(2,'D',5),
(3,'A',14),(3,'B',67),(3,'D',8);
hostid A B C D
1 10 3 0 0
2 9 0 40 5
3 14 67 0 8

You can use .present? which comes included with ActiveSupport.
@city = @user.city.present?
# etc ...
You could even write it like this
def show
%w(city state bio contact twitter mail).each do |attr|
instance_variable_set "@#{attr}", @user[attr].present?
end
end
It's worth noting that if you want to test if something is blank, you can use .blank?
(this is the opposite of .present?
)
Also, don't use foo == nil
. Use foo.nil?
instead.
You need to understand the content in M2E_plugin_execution_not_covered and follow the steps mentioned below:
<ignore/>
under <action>
tags.eg: for write-project-properties error, add this snippet under the <pluginExecutions>
section of the lifecycle-mapping-metadata.xml file:
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<versionRange>1.0-alpha-2</versionRange>
<goals>
<goal>write-project-properties</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore />
</action>
</pluginExecution>
You should see no errors in the future for any project.
I got this error because I renamed my View (and POST action).
Finally I found that I forgot to rename BOTH GET and POST actions to new name.
Solution : Rename both GET and POST actions to match the View name.
Moved from the closed topic
del /s d:\test\archive*.txt
This should get you all of your text files
Alternatively,
I modified a script I already wrote to look for certain files to move them, this one should go and find files and delete them. It allows you to just choose to which folder by a selection screen.
Please test this on your system before using it though.

If you change the

to the folder you want you won't get prompted for the folder. *Remember when putting the base path in, the format does not include a '\' on the end. e.g. d:\test c:\temp

Problem is not about your main function. Check out for
javac -d . -cp ./apache-log4j-1.2.16/log4j-1.2.16.jar:./vensim.jar SpatialModel.java VensimHelper.java VensimException.java VensimContextRepository.java
output and run it.
@Test(expected = Exception.class)
Tells Junit that exception is the expected result so test will be passed (marked as green) when exception is thrown.
For
@Test
Junit will consider test as failed if exception is thrown, provided it's an unchecked exception. If the exception is checked it won't compile and you will need to use other methods. This link might help.
If using latest Git,
git merge --abort
else this will do the job in older git versions

For a string of length 1 you can simply perform isdigit()
or isalpha()
If your string length is greater than 1, you can make a function something like..
def isinteger(a):
try:
int(a)
return True
except ValueError:
return False
Due to https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html#option_mysqldump_lock-tables :
Some options, such as --opt (which is enabled by default), automatically enable --lock-tables. If you want to override this, use --skip-lock-tables at the end of the option list.
You could try this
=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),FALSE, TRUE)
-or-
=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),"FALSE", "File found in row " & MATCH(<single column I value>,<entire column E range>,0))
you could replace <single column I value>
and <entire column E range>
with named ranged. That'd probably be the easiest.
Just drag that formula all the way down the length of your I column in whatever column you want.
I generally use a small jQuery snippet globally to open any external links in a new tab / window. I've added the selector for a form for my own site and it works fine so far:
// URL target
$('a[href*="//"]:not([href*="'+ location.hostname +'"]),form[action*="//"]:not([href*="'+ location.hostname +'"]').attr('target','_blank');
mark the java folder as source root.It will solve.
You can also pass in a variable and/or object if you wanted to.
var str1:String = "John"
var str2:String = "Bob"
var myArray = ["Steve", "Bill", "Linus", "Bret"]
//add to the end of the array with append
myArray.append(str1)
myArray.append(str2)
To add them to the front:
//use 'insert' instead of append
myArray.insert(str1, atIndex:0)
myArray.insert(str2, atIndex:0)
//Swift 3
myArray.insert(str1, at: 0)
myArray.insert(str2, at: 0)
As others have already stated, you can no longer use '+=' as of xCode 6.1
Since the soft keyboard is part of the OS, more often than not, you won't be able to hide it - also, on iOS, hiding the keyboard drops focus from the element.
However, if you use the onFocus
attribute on the input, and then blur()
the text input immediately, the keyboard will hide itself and the onFocus
event can set a variable to define which text input was focused last.
Then alter your on-page keyboard to only alter the last-focused (check using the variable) text input, rather than simulating a key press.
When looking at an input with a type of number, you'll notice the spinner buttons (up/down) on the right-hand side of the input field. These spinners aren't always desirable, thus the code below removes such styling to render an input that resembles that of an input with a type of text.
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
}

Why Lists Can't Be Dictionary Keys
Newcomers to Python often wonder why, while the language includes both a tuple and a list type, tuples are usable as a dictionary keys, while lists are not. This was a deliberate design decision, and can best be explained by first understanding how Python dictionaries work.
Source & more info: http://wiki.python.org/moin/DictionaryKeys
The most obvious to me would be:
np.any(my_array[:, 0] == value)
You can also use string.match().
var string1 = "aBc";
var match = string1.match(/AbC/i);
if(match) {
}
\b
matches at word boundaries (without actually matching any characters), so the following should do what you want:

Here's a working plunker.
The cleanest solution is to use Auto Layout. I lowered Content Compression Resistance Priority of my UIButton
and set the image (not Background Image) via Interface Builder. After that I added a couple of constraints that define size of my button (quite complex in my case) and it worked like a charm.
For anyone reading who wants ONLY the time in the output, you can pass options to JavaScript's Date::toLocaleString() method. Example:
var date = new Date("February 04, 2011 19:00:00");_x000D_
var options = {_x000D_
hour: 'numeric',_x000D_
minute: 'numeric',_x000D_
hour12: true_x000D_
};_x000D_
var timeString = date.toLocaleString('en-US', options);_x000D_
console.log(timeString);
_x000D_
timeString will be set to:
8:00 AM
Add "second: 'numeric'" to your options if you want seconds too. For all option see this.
Naïve approach:
a = "A long string with a . in the middle ending with ."
fchar = '.'
rchar = '. -'
a[::-1].replace(fchar, rchar[::-1], 1)[::-1]
Out[2]: 'A long string with a . in the middle ending with . -'
Aditya Sihag's answer with a single rfind
:
pos = a.rfind('.')
a[:pos] + '. -' + a[pos+1:]
If no table with such name exists, DROP
fails with error while DROP IF EXISTS
just does nothing.
This is useful if you create/modifi your database with a script; this way you do not have to ensure manually that previous versions of the table are deleted. You just do a DROP IF EXISTS
and forget about it.
Of course, your current DB engine may not support this option, it is hard to tell more about the error with the information you provide.
you could use this
curl_setopt($curl->curl, CURLOPT_SSL_VERIFYPEER, false);
As of C++20, yes.
As of C++17, you can use string_view
:
constexpr std::string_view sv = "hello, world";
A string_view
is a string
-like object that acts as an immutable, non-owning reference to any sequence of char
objects.
Try using rowMeans
:
z$mean=rowMeans(z[,c("x", "y")], na.rm=TRUE)
w x y mean
1 5 1 1 1
2 6 2 2 2
3 7 3 3 3
4 8 4 NA 4
In PHP, you'll need to either use the multibyte functions, or turn on mbstring.func_overload. That way things like strlen will work if you have characters that take more than one byte.
You'll also need to identify the character set of your responses. You can either use AddDefaultCharset, as above, or write PHP code that returns the header. (Or you can add a META tag to your HTML documents.)
You can insert an image that looks like a button. Then attach a script to the image.

answers above are good enough to show how to build the library, but how to collect the headers are still tricky. here I share the little script I use to copy the necessary headers.
SOURCE

DST
is the second param, which is the include directory
holds the collected headers. (eg. in cmake, include_directories(./collected_headers_here)
).

SOURCE=$1
DST=$2

echo "-- source dir is $SOURCE"

mkdir $DST

mkdir -p $DST/tensorflow
cp -r $SOURCE/tensorflow/core $DST/tensorflow
cp -r $SOURCE/tensorflow/cc $DST/tensorflow
cp -r $SOURCE/tensorflow/c $DST/tensorflow
# 2. copy the generated code, put them back to
# the right directories along side the source code
if [[ -e $SOURCE/bazel-genfiles/tensorflow ]];then
prefix="$SOURCE/bazel-genfiles/tensorflow"
from=$(expr $(echo -n $prefix | wc -m) + 1)
# eg. compiled protobuf files
find $SOURCE/bazel-genfiles/tensorflow -type f | while read line;do
#echo "procese file --> $line"
line_len=$(echo -n $line | wc -m)

# In the tf source code, you can see #include "third_party/...", so you need it
cp -r $SOURCE/third_party $DST

A somewhat different approach (at least on Android) is to use the IntDef annotation to combine a set of int constants
@IntDef({NOTAX, SALESTAX, IMPORTEDTAX})
@interface TAX {}
int NOTAX = 0;
int SALESTAX = 10;
int IMPORTEDTAX = 5;
Use as function parameter:
void computeTax(@TAX int taxPercentage){...}
or in a variable declaration:
@TAX int currentTax = IMPORTEDTAX;
By default Entity Framework uses lazy-loading for navigation properties. That's why these properties should be marked as virtual - EF creates proxy class for your entity and overrides navigation properties to allow lazy-loading. E.g. if you have this entity:
public class MemberLoan
{
public string LoandProviderCode { get; set; }
public virtual Membership Membership { get; set; }
}
Entity Framework will return proxy inherited from this entity and provide DbContext instance to this proxy in order to allow lazy loading of membership later:
public class MemberLoanProxy : MemberLoan
{
private CosisEntities db;
private int membershipId;
private Membership membership;
public override Membership Membership
{
get
{
if (membership == null)
membership = db.Memberships.Find(membershipId);
return membership;
}
set { membership = value; }
}
}
So, entity has instance of DbContext which was used for loading entity. That's your problem. You have using
block around CosisEntities usage. Which disposes context before entities are returned. When some code later tries to use lazy-loaded navigation property, it fails, because context is disposed at that moment.
To fix this behavior you can use eager loading of navigation properties which you will need later:
IQueryable<MemberLoan> query = db.MemberLoans.Include(m => m.Membership);
That will pre-load all memberships and lazy-loading will not be used. For details see Loading Related Entities article on MSDN.
You missed some breaks there:
switch (searchType)
{
case "SearchBooks":
Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
break;
case "SearchAuthors":
Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
break;
}
Without them, the compiler thinks you're trying to execute the lines below case "SearchAuthors":
immediately after the lines under case "SearchBooks":
have been executed, which isn't allowed in C#.
By adding the break
statements at the end of each case, the program exits each case after it's done, for whichever value of searchType
.
There's no way this could influence anything in Java, since there's no (direct non-API) way to map some bytes directly into an int in Java.
Every API that does this or something similar defines the behaviour pretty precisely, so you should look up the documentation of that API.
Different IIS web servers can process different amounts of data in the 'header', according to this (now deleted) article; http://classicasp.aspfaq.com/forms/what-is-the-limit-on-form/post-parameters.html;
Note that there is no limit on the number of FORM elements you can pass via POST, but only on the aggregate size of all name/value pairs. While GET is limited to as low as 1024 characters, POST data is limited to 2 MB on IIS 4.0, and 128 KB on IIS 5.0. Each name/value is limited to 1024 characters, as imposed by the SGML spec. Of course this does not apply to files uploaded using enctype='multipart/form-data' ... I have had no problems uploading files in the 90 - 100 MB range using IIS 5.0, aside from having to increase the server.scriptTimeout value as well as my patience!
In most regex dialects there are a set of convenient character summaries you can use for this kind of thing - these are good ones to remember:
\w
- Matches any word character.
\W
- Matches any nonword character.
\s
- Matches any white-space character.
\S
- Matches anything but white-space characters.
\d
- Matches any digit.
\D
- Matches anything except digits.
A search for "Regex Cheatsheets" should reward you with a whole lot of useful summaries.

By encasing the input type="button" within a hyperlink element, you can simply declare the target property as so:

<input type="button" class="button" value="Open" />
</a>
The 'target="_blank"' is the property which makes the browser open the link within a new tab. This attribute has other properties, See: http://www.w3schools.com/tags/att_a_target.asp for further details.
Since the 'value=""' attribute on buttons will write the contained string to the button, a span is not necessary.
Instead of writing:
<element></element>
for most HTML elements you can simply close them with a trailing slash, like so:
<element />
Oh, and finally... a 'button' element has a refresh trigger within it, so I use an 'input type[button]' to avoid triggering the form.
Good Luck Programmers.
Due to StackOverflow's policy I had to change the domain in the example: https://meta.stackexchange.com/questions/208963/why-are-certain-example-urls-like-http-site-com-and-http-mysite-com-blocke
test = data.frame(C=c(0,2,4, 7, 8), A=c(4,2,4, 7, 8), B=c(1, 3, 8,3,2))
Using the simple following function replacement can be performed (but only if data frame does not have many columns):
test <- test[, c("A", "B", "C")]
for others:
test <- test[, c("B", "A", "C")]
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
//to prevent double click
button.setOnClickListener(null);
}
});
This is the simpler and flexible way I found (based on @prunge answer)
Optional<User> user = users.stream()
.filter(user -> user.getId() == 1)
.reduce((a, b) -> {
throw new IllegalStateException("Multiple elements: " + a + ", " + b);
})
This way you obtain:
Optional.empty()
if not presentYou should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3
(and uses it as default), so switch back to a value of 2
which can be read by Python 2.
Check the protocol
parameter in pickle.dump
. Your resulting code will look like this.
pickle.dump(your_object, your_file, protocol=2)
There is no protocol
parameter in pickle.load
because pickle
can determine the protocol from the file.
In case you are targeting Win32 platforms or NT kernel mode, you should have a look at cfix.
<input class="messageCheckbox" type="checkbox" onchange="getValue(this.value)" value="3" name="mailId[]">
<input class="messageCheckbox" type="checkbox" onchange="getValue(this.value)" value="1" name="mailId[]">
function getValue(value){
alert(value);
}
finally solved my problem.
I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.
This is a great question (+1) and the answers were almost helpful ;) Sorry guys, but I had a heck of a time slogging through this, though both Gonso & AVeryDev gave good hints. Hopefully, this answer will help others.
MyVC
is the view controller holding all this stuff.
MySubview
is the view that we want to load from a xib
MySubView
that is the right size & shape & positioned where you want it.In MyVC.h, have
IBOutlet MySubview *mySubView
// ...
@property (nonatomic, retain) MySubview *mySubview;
In MyVC.m, @synthesize mySubView;
and don't forget to release it in dealloc
.
UIView *view
(may be unnecessary, but worked for me.) Synthesize & release it in .mMySubview
, and link the view property to your view.IBOutlet
's as desiredBack in MyVC.m, have
NSArray *xibviews = [[NSBundle mainBundle] loadNibNamed: @"MySubview" owner: mySubview options: NULL];
MySubview *msView = [xibviews objectAtIndex: 0];
msView.frame = mySubview.frame;
UIView *oldView = mySubview;
// Too simple: [self.view insertSubview: msView aboveSubview: mySubview];
[[mySubview superview] insertSubview: msView aboveSubview: mySubview]; // allows nesting
self.mySubview = msView;
[oldCBView removeFromSuperview];
The tricky bit for me was: the hints in the other answers loaded my view from the xib, but did NOT replace the view in MyVC (duh!) -- I had to swap that out on my own.
Also, to get access to mySubview
's methods, the view
property in the .xib file must be set to MySubview
. Otherwise, it comes back as a plain-old UIView
.
If there's a way to load mySubview
directly from its own xib, that'd rock, but this got me where I needed to be.
Accepted answer doesn't work with "use strict" as the "with" statement throws an error. So instead:
$.post(url, function (data) {
var w = window.open('about:blank', 'windowname');
w.document.write(data);
w.document.close();
});
Also, make sure 'windowname' doesn't have any spaces in it because that will fail in IE :)
I have two demos, one with jQuery
and one without. Neither use date functions and are about as simple as it gets.
function startTimer(duration, display) {_x000D_
var timer = duration, minutes, seconds;_x000D_

}_x000D_
_x000D_
window.onload = function () {_x000D_
var fiveMinutes = 60 * 5,_x000D_

startTimer(fiveMinutes, display);_x000D_
};

_x000D_
function startTimer(duration, display) {
var timer = duration, minutes, seconds;
setInterval(function () {
minutes = parseInt(timer / 60, 10);
seconds = parseInt(timer % 60, 10);
minutes = minutes < 10 ? "0" + minutes : minutes;
seconds = seconds < 10 ? "0" + seconds : seconds;
display.text(minutes + ":" + seconds);
if (--timer < 0) {
timer = duration;
}
}, 1000);
}
jQuery(function ($) {
var fiveMinutes = 60 * 5,
display = $('#time');
startTimer(fiveMinutes, display);
});
However if you want a more accurate timer that is only slightly more complicated:
function startTimer(duration, display) {_x000D_
var start = Date.now(),_x000D_
diff,_x000D_
minutes,_x000D_
seconds;_x000D_
function timer() {_x000D_
// get the number of seconds that have elapsed since _x000D_
// startTimer() was called_x000D_
diff = duration - (((Date.now() - start) / 1000) | 0);_x000D_
_x000D_
// does the same job as parseInt truncates the float_x000D_
minutes = (diff / 60) | 0;_x000D_
seconds = (diff % 60) | 0;_x000D_
_x000D_
minutes = minutes < 10 ? "0" + minutes : minutes;_x000D_
seconds = seconds < 10 ? "0" + seconds : seconds;_x000D_
_x000D_
display.textContent = minutes + ":" + seconds; _x000D_
_x000D_
if (diff <= 0) {_x000D_
// add one second so that the count down starts at the full duration_x000D_
// example 05:00 not 04:59_x000D_
start = Date.now() + 1000;_x000D_
}_x000D_
};_x000D_
// we don't want to wait a full second before the timer starts_x000D_
timer();_x000D_
setInterval(timer, 1000);_x000D_
}_x000D_
_x000D_
window.onload = function () {_x000D_
var fiveMinutes = 60 * 5,_x000D_
display = document.querySelector('#time');_x000D_
startTimer(fiveMinutes, display);_x000D_
};
_x000D_
<body>_x000D_
<div>Registration closes in <span id="time"></span> minutes!</div>_x000D_
</body>
_x000D_
Now that we have made a few pretty simple timers we can start to think about re-usability and separating concerns. We can do this by asking "what should a count down timer do?"
So with these things in mind lets write a better (but still very simple) CountDownTimer
function CountDownTimer(duration, granularity) {
this.duration = duration;
this.granularity = granularity || 1000;
this.tickFtns = [];
this.running = false;
}
CountDownTimer.prototype.start = function() {
if (this.running) {
return;
}
this.running = true;
var start = Date.now(),
that = this,
diff, obj;
(function timer() {
diff = that.duration - (((Date.now() - start) / 1000) | 0);
if (diff > 0) {
setTimeout(timer, that.granularity);
} else {
diff = 0;
that.running = false;
}
obj = CountDownTimer.parse(diff);
that.tickFtns.forEach(function(ftn) {
ftn.call(this, obj.minutes, obj.seconds);
}, that);
}());
};
CountDownTimer.prototype.onTick = function(ftn) {
if (typeof ftn === 'function') {
this.tickFtns.push(ftn);
}
return this;
};
CountDownTimer.prototype.expired = function() {
return !this.running;
};
CountDownTimer.parse = function(seconds) {
return {
'minutes': (seconds / 60) | 0,
'seconds': (seconds % 60) | 0
};
};
So why is this implementation better than the others? Here are some examples of what you can do with it. Note that all but the first example can't be achieved by the startTimer
functions.
An example that displays the time in XX:XX format and restarts after reaching 00:00
An example that displays the time in two different formats
An example that has two different timers and only one restarts
An example that starts the count down timer when a button is pressed
This, from the masters themselves (K&R, 2nd ed., pg. 106):
// strcmp: return < 0 if s < t, 0 if s == t, > 0 if s > t
int strcmp(char *s, char *t)
{
int i;
for (i = 0; s[i] == t[i]; i++)
if (s[i] == '\0')
return 0;
return s[i] - t[i];
}
This can be done in a much simpler manner now.
$tmpName = $_FILES['csv']['tmp_name'];
$csvAsArray = array_map('str_getcsv', file($tmpName));
This will return you a parsed array of your CSV data. Then you can just loop through it using a foreach statement.
You can use tabindex="-1"
.
The W3C HTML5 specification supports negative tabindex
values:
If the value is a negative integer
The user agent must set the element's tabindex focus flag, but should not allow the element to be reached using sequential focus navigation.
Watch out though that this is a HTML5 feature and might not work with old browsers.
To be W3C HTML 4.01 standard (from 1999) compliant, tabindex would need to be positive.
Sample usage below in pure HTML.
<input />_x000D_
<input tabindex="-1" placeholder="NoTabIndex" />_x000D_
<input />
_x000D_
Another way is to use FIXED
function, you can specify the number of decimal places but it defaults to 2 if the places aren't specified, i.e.
=FIXED(E5,2)
or just
=FIXED(E5)
You can solve the problem with the global solution, but firstly I want to describe the solution for each project individually, cause of trustfully compatibility with most of Git clients and other implemented Git environments:
Go to the following location:
Local/repo/location/.git/
open "config" file there, and set your parameters like the example (add to the end of the file):
[user]
name = YOUR-NAME
email = YOUR-EMAIL-ADDRESS
Open a command line and type:
git config --global user.email "[email protected]"
git config --global user.name "YOUR NAME"
Placing code in a using block ensures that the objects are disposed (though not necessarily collected) as soon as control leaves the block.
LinkedHashSet
's constructors invoke the following base class constructor:
HashSet(int initialCapacity, float loadFactor, boolean dummy) {
map = new LinkedHashMap<E, Object>(initialCapacity, loadFactor);
}
As you can see, the internal map is a LinkedHashMap
. If you look inside LinkedHashMap
, you'll discover the following field:
private transient Entry<K, V> header;
This is the linked list in question.
Installation code chunks for vanilla Sublime may change in the future.
This link would be the safest place to install plugin support to Sublime Text 2.
For Sublime Text 3 this link works has the code.
There is now a new way of addressing this issue - if you remove position: relative from the container which needs to have the overflow-y visible, you can have overflow-y visible and overflow-x hidden, and vice versa (have overflow-x visible and overflow-y hidden, just make sure the container with the visible property is not relatively positioned).

You do not need to use ORDER BY
in inner query after WHERE
clause because you have already used it in ROW_NUMBER() OVER (ORDER BY VRDATE DESC)
.
SELECT
*
FROM (
SELECT
Stockmain.VRNOA,
item.description as item_description,
party.name as party_name,
stockmain.vrdate,
stockdetail.qty,
stockdetail.rate,
stockdetail.amount,
ROW_NUMBER() OVER (ORDER BY VRDATE DESC) AS RowNum --< ORDER BY
FROM StockMain
INNER JOIN StockDetail
ON StockMain.stid = StockDetail.stid
INNER JOIN party
ON party.party_id = stockmain.party_id
INNER JOIN item
ON item.item_id = stockdetail.item_id
WHERE stockmain.etype='purchase'
) AS MyDerivedTable
WHERE
MyDerivedTable.RowNum BETWEEN 1 and 5
EDIT: this solution is now in the original answer too.
The accepted answer is not quite correct. You should not be using the position() function since it is relative to the parent. If you are doing global positioning(in most cases?) you should only add the offset top with the outerheight like so:
var actualBottom = $(selector).offset().top + $(selector).outerHeight(true);
The docs http://api.jquery.com/offset/
I'm reluctant to add yet another answer, but I've had to beg, borrow and steal from the others to get what I want, which is a complete list of all the FK relationships on tables in a given schema, INCLUDING FKs to tables in other schemas. The two crucial recordsets are information_schema.KEY_COLUMN_USAGE and information_schema.referential_constraints. If an attribute you want is missing, just uncomment the KCU., RC. to see what's available
SELECT DISTINCT KCU.TABLE_NAME, KCU.COLUMN_NAME, REFERENCED_TABLE_SCHEMA, KCU.REFERENCED_TABLE_NAME, KCU.REFERENCED_COLUMN_NAME, UPDATE_RULE, DELETE_RULE #, KCU.*, RC.*
FROM information_schema.KEY_COLUMN_USAGE KCU
INNER JOIN information_schema.referential_constraints RC ON KCU.CONSTRAINT_NAME = RC.CONSTRAINT_NAME
WHERE TABLE_SCHEMA = (your schema name)
AND KCU.REFERENCED_TABLE_NAME IS NOT NULL
ORDER BY KCU.TABLE_NAME, KCU.COLUMN_NAME;
Apache Commons Lang's replaceEach method may come in handy dependeding on your specific needs. You can easily use it to replace placeholders by name with this single method call:
StringUtils.replaceEach("There's an incorrect value '%(value)' in column # %(column)",
new String[] { "%(value)", "%(column)" }, new String[] { x, y });
Given some input text, this will replace all occurrences of the placeholders in the first string array with the corresponding values in the second one.
List<String> myStringList = new List<string>(); foreach (string s in myStringArray) { if (!myStringList.Contains(s)) { myStringList.Add(s); } }
This is O(n^2), which won't matter for a short list which is going to be stuffed into a combo, but could be rapidly be a problem on a big collection.
Lots of reads in every query, fewer regular writes
Both databases perform well on reads where the hot data set fits in memory. Both also emphasize join-less data models (and encourage denormalization instead), and both provide indexes on documents or rows, although MongoDB's indexes are currently more flexible.
Cassandra's storage engine provides constant-time writes no matter how big your data set grows. Writes are more problematic in MongoDB, partly because of the b-tree based storage engine, but more because of the multi-granularity locking it does.
For analytics, MongoDB provides a custom map/reduce implementation; Cassandra provides native Hadoop support, including for Hive (a SQL data warehouse built on Hadoop map/reduce) and Pig (a Hadoop-specific analysis language that many think is a better fit for map/reduce workloads than SQL). Cassandra also supports use of Spark.
Not worried about "massive" scalability
If you're looking at a single server, MongoDB is probably a better fit. For those more concerned about scaling, Cassandra's no-single-point-of-failure architecture will be easier to set up and more reliable. (MongoDB's global write lock tends to become more painful, too.) Cassandra also gives a lot more control over how your replication works, including support for multiple data centers.
More concerned about simple setup, maintenance and code
Both are trivial to set up, with reasonable out-of-the-box defaults for a single server. Cassandra is simpler to set up in a multi-server configuration since there are no special-role nodes to worry about.
If you're presently using JSON blobs, MongoDB is an insanely good match for your use case, given that it uses BSON to store the data. You'll be able to have richer and more queryable data than you would in your present database. This would be the most significant win for Mongo.
The workarounds above (thanks!) don't properly address the problem of getting back the objects provided to the deferred's resolve()
method because jQuery calls the done()
and fail()
callbacks with individual parameters, not an array. That means we have to use the arguments
pseudo-array to get all the resolved/rejected objects returned by the array of deferreds, which is ugly:
$.when.apply($,deferreds).then(function() {
var objects=arguments; // The array of resolved objects as a pseudo-array
...
};
Since we passed in an array of deferreds, it would be nice to get back an array of results. It would also be nice to get back an actual array instead of a pseudo-array so we can use methods like Array.sort()
.
Here is a solution inspired by when.js's when.all()
method that addresses these problems:
// Put somewhere in your scripting environment
if (typeof jQuery.when.all === 'undefined') {
jQuery.when.all = function (deferreds) {
return $.Deferred(function (def) {
$.when.apply(jQuery, deferreds).then(
function () {
def.resolveWith(this, [Array.prototype.slice.call(arguments)]);
},
function () {
def.rejectWith(this, [Array.prototype.slice.call(arguments)]);
});
});
}
}
Now you can simply pass in an array of deferreds/promises and get back an array of resolved/rejected objects in your callback, like so:
$.when.all(deferreds).then(function(objects) {
console.log("Resolved objects:", objects);
});
don't know windows 8 but you can probably set the default prog for a specific extension, for example on windows 7 you do right click => open with, then you select the prog you want and select 'use this prog as default', or you can remove your old version of python from your path and add the one of the anaconda
In Linux, this information is available in the /proc file system. I'm not a big fan of the text file format used, as each Linux distribution seems to customize at least one important file. A quick look as the source to 'ps' reveals the mess.

For CPU utilization, you have to do a little work. Linux makes available overall CPU utilization since system start; this probably isn't what you are interested in. If you want to know what the CPU utilization was for the last second, or 10 seconds, then you need to query the information and calculate it yourself.
The information is available in /proc/stat, which is documented pretty well at http://www.linuxhowtos.org/System/procstat.htm; here is what it looks like on my 4-core box:
Anderson cxc # more /proc/stat
cpu 2329889 0 2364567 1063530460 9034 9463 96111 0

First, you need to determine how many CPUs (or processors, or processing cores) are available in the system. To do this, count the number of 'cpuN' entries, where N starts at 0 and increments. Don't count the 'cpu' line, which is a combination of the cpuN lines. In my example, you can see cpu0 through cpu3, for a total of 4 processors. From now on, you can ignore cpu0..cpu3, and focus only on the 'cpu' line.
Next, you need to know that the fourth number in these lines is a measure of idle time, and thus the fourth number on the 'cpu' line is the total idle time for all processors since boot time. This time is measured in Linux "jiffies", which are 1/100 of a second each.
But you don't care about the total idle time; you care about the idle time in a given period, e.g., the last second. Do calculate that, you need to read this file twice, 1 second apart.Then you can do a diff of the fourth value of the line. For example, if you take a sample and get:
cpu 2330047 0 2365006 1063853632 9035 9463 96114 0
Then one second later you get this sample:
cpu 2330047 0 2365007 1063854028 9035 9463 96114 0
Subtract the two numbers, and you get a diff of 396, which means that your CPU had been idle for 3.96 seconds out of the last 1.00 second. The trick, of course, is that you need to divide by the number of processors. 3.96 / 4 = 0.99, and there is your idle percentage; 99% idle, and 1% busy.
In my code, I have a ring buffer of 360 entries, and I read this file every second. That lets me quickly calculate the CPU utilization for 1 second, 10 seconds, etc., all the way up to 1 hour.
For the process-specific information, you have to look in /proc/pid; if you don't care abut your pid, you can look in /proc/self.
CPU used by your process is available in /proc/self/stat. This is an odd-looking file consisting of a single line; for example:
19340 (whatever) S 19115 19115 3084 34816 19115 4202752 118200 607 0 0 770 384 2
7 20 0 77 0 266764385 692477952 105074 4294967295 134512640 146462952 321468364
8 3214683328 4294960144 0 2147221247 268439552 1276 4294967295 0 0 17 0 0 0 0
The important data here are the 13th and 14th tokens (0 and 770 here). The 13th token is the number of jiffies that the process has executed in user mode, and the 14th is the number of jiffies that the process has executed in kernel mode. Add the two together, and you have its total CPU utilization.
Again, you will have to sample this file periodically, and calculate the diff, in order to determine the process's CPU usage over time.
Edit: remember that when you calculate your process's CPU utilization, you have to take into account 1) the number of threads in your process, and 2) the number of processors in the system. For example, if your single-threaded process is using only 25% of the CPU, that could be good or bad. Good on a single-processor system, but bad on a 4-processor system; this means that your process is running constantly, and using 100% of the CPU cycles available to it.
For the process-specific memory information, you ahve to look at /proc/self/status, which looks like this:
Name: whatever
State: S (sleeping)

The only item I'm not sure about is Swapspace currently used by my process. I don't know if this is available.
I wonder why you find as solution the "white-space" with "nowrap" or "pre", it is not doing the correct behaviour: you force your text in a single line! The text should break lines, but not break words as default. This is caused by some css attributes: word-wrap, overflow-wrap, word-break, and hyphens. So you can have either:
word-break: break-all;
word-wrap: break-word;
overflow-wrap: break-word;
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;
So the solution is remove them, or override them with "unset" or "normal":
word-break: unset;
word-wrap: unset;
overflow-wrap: unset;
-webkit-hyphens: unset;
-moz-hyphens: unset;
-ms-hyphens: unset;
hyphens: unset;
UPDATE: i provide also proof with JSfiddle: https://jsfiddle.net/azozp8rr/
Simply call the ordinal()
method on an enum value, to retrieve its corresponding number. There's no need to declare an addition attribute with its value, each enumerated value gets its own number by default, assigned starting from zero, incrementing by one for each value in the same order they were declared.
You shouldn't depend on the int
value of an enum
, only on its actual value. Enums in Java are a different kind of monster and are not like enums in C, where you depend on their integer code.
Regarding the example you provided in the question, Font.PLAIN
works because that's just an integer constant of the Font class. If you absolutely need a (possibly changing) numeric code, then an enum
is not the right tool for the job, better stick to numeric constants.

Take this example:
original = dict(a=1, b=2, c=dict(d=4, e=5))
new = original.copy()
Now let's change a value in the 'shallow' (first) level:
new['a'] = 10
# new = {'a': 10, 'b': 2, 'c': {'d': 4, 'e': 5}}
# original = {'a': 1, 'b': 2, 'c': {'d': 4, 'e': 5}}
# no change in original, since ['a'] is an immutable integer
Now let's change a value one level deeper:
new['c']['d'] = 40
# new = {'a': 10, 'b': 2, 'c': {'d': 40, 'e': 5}}
# original = {'a': 1, 'b': 2, 'c': {'d': 40, 'e': 5}}
# new['c'] points to the same original['d'] mutable dictionary, so it will be changed

If boolean() is not available (the tool I'm using does not) one way to achieve it is:
//SELECT[@id='xpto']/OPTION[not(not(@selected))]
In this case, within the /OPTION, one of the options is the selected one. The "selected" does not have a value... it just exists, while the other OPTION do not have "selected". This achieves the objective.
parseDouble
returns a primitive double containing the value of the string:
Returns a new double initialized to the value represented by the specified String, as performed by the valueOf method of class Double.
valueOf
returns a Double instance, if already cached, you'll get the same cached instance.
Returns a Double instance representing the specified double value. If a new Double instance is not required, this method should generally be used in preference to the constructor Double(double), as this method is likely to yield significantly better space and time performance by caching frequently requested values.
To avoid the overhead of creating a new Double object instance, you should normally use valueOf

In the spirit of functional programming
You're so close it's crazy.
if($(this).attr("name"))
There's no hasAttr but hitting an attribute by name will just return undefined if it doesn't exist.
This is why the below works. If you remove the name attribute from #heading the second alert will fire.
Update: As per the comments, the below will ONLY work if the attribute is present AND is set to something not if the attribute is there but empty
<script type="text/javascript">
$(document).ready(function()
{
if ($("#heading").attr("name"))
alert('Look, this is showing because it\'s not undefined');
else
alert('This would be called if it were undefined or is there but empty');
});
</script>
<h1 id="heading" name="bob">Welcome!</h1>
I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:
.ui-helper-center {
text-align: center;
}
And then add the ui-helper-center
class to the table cells for which you wish to control the alignment:
<td class="ui-helper-center">Content</td>
EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.
See Gabe's answer for how to include the CSS rule into your page.

Nice question, a while ago I've experimented a bit with this, but haven't used it a lot because it's still not bulletproof. I divided the plot area into a 32x32 grid and calculated a 'potential field' for the best position of a label for each line according the following rules:
The code was something like this:
import matplotlib.pyplot as plt
import numpy as np
from scipy import ndimage
def my_legend(axis = None):
if axis == None:
axis = plt.gca()
N = 32
Nlines = len(axis.lines)
print Nlines
xmin, xmax = axis.get_xlim()
ymin, ymax = axis.get_ylim()
# the 'point of presence' matrix
pop = np.zeros((Nlines, N, N), dtype=np.float)
for l in range(Nlines):
# get xy data and scale it to the NxN squares
xy = axis.lines[l].get_xydata()
xy = (xy - [xmin,ymin]) / ([xmax-xmin, ymax-ymin]) * N
xy = xy.astype(np.int32)
# mask stuff outside plot
mask = (xy[:,0] >= 0) & (xy[:,0] < N) & (xy[:,1] >= 0) & (xy[:,1] < N)
xy = xy[mask]
# add to pop
for p in xy:
pop[l][tuple(p)] = 1.0
# find whitespace, nice place for labels
ws = 1.0 - (np.sum(pop, axis=0) > 0) * 1.0
# don't use the borders
ws[:,0] = 0
ws[:,N-1] = 0
ws[0,:] = 0
ws[N-1,:] = 0
# blur the pop's
for l in range(Nlines):
pop[l] = ndimage.gaussian_filter(pop[l], sigma=N/5)
for l in range(Nlines):
# positive weights for current line, negative weight for others....
w = -0.3 * np.ones(Nlines, dtype=np.float)
w[l] = 0.5
# calculate a field
p = ws + np.sum(w[:, np.newaxis, np.newaxis] * pop, axis=0)
plt.figure()
plt.imshow(p, interpolation='nearest')
plt.title(axis.lines[l].get_label())
pos = np.argmax(p) # note, argmax flattens the array first
best_x, best_y = (pos / N, pos % N)
x = xmin + (xmax-xmin) * best_x / N
y = ymin + (ymax-ymin) * best_y / N
axis.text(x, y, axis.lines[l].get_label(),
horizontalalignment='center',
verticalalignment='center')
plt.close('all')
x = np.linspace(0, 1, 101)
y1 = np.sin(x * np.pi / 2)
y2 = np.cos(x * np.pi / 2)
y3 = x * x
plt.plot(x, y1, 'b', label='blue')
plt.plot(x, y2, 'r', label='red')
plt.plot(x, y3, 'g', label='green')
my_legend()
plt.show()
And the resulting plot:
since you set your itemsource to your collection, your textbox is tied to each individual item in that collection. the selected item property is useful in this scenario if you were trying to do a master-detail form, having 2 listboxes. you would bind the second listbox's itemsource to the child collection of rules. in otherwords the selected item alerts outside controls that your source has changed, internal controls(those inside your datatemplate already are aware of the change.
and to answer your question yes in most circumstances setting the itemsource is the same as setting the datacontext of the control.
Open:
Start Menu
-> Programs
-> Microsoft Visual Studio 2010
-> Visual Studio Tools
-> Visual Studio Command Prompt (2010)
Run in command prompt:
aspnet_regiis -i
Make sure it is run at administrator, check that the title starts with Administrator
:
You can find if the textbox is disabled using is
method by passing :disabled
selector to it. Try this.
if($('textbox').is(':disabled')){
//textbox is disabled
}
Go to %appdata%\Notepad++ folder.
The macro definitions are held in shortcuts.xml inside the <Macros>
tag. You can copy the whole file, or copy the tag and paste it into shortcuts.xml at the other location.
In the latter case, be sure to use another editor, since N++ overwrites shortcuts.xml on exit.
One more thing... If you already ignored those files through Eclipse (with Team -> Ignored resources) you have to undo these settings so the files are controlled by Subclipse again and "Add to svn:ignore" option reappears
olivierg's answer worked for me and is the best solution if creating a custom Dialog class is the route you want to go. However, it bothered me that I couldn't use the AlertDialog class. I wanted to be able to use the default system AlertDialog style. Creating a custom dialog class would not have this style.
So I found a solution (hack) that will work without having to create a custom class, you can use the existing builders.
The AlertDialog puts a View above your content view as a placeholder for the title. If you find the view and set the height to 0, the space goes away.
I have tested this on 2.3 and 3.0 so far, it is possible it doesn't work on every version yet.
Here are two helper methods for doing it:
/**
* Show a Dialog with the extra title/top padding collapsed.
*
* @param customView The custom view that you added to the dialog
* @param dialog The dialog to display without top spacing
* @param show Whether or not to call dialog.show() at the end.
*/
public static void showDialogWithNoTopSpace(final View customView, final Dialog dialog, boolean show) {
// Now we setup a listener to detect as soon as the dialog has shown.
customView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
// Check if your view has been laid out yet
if (customView.getHeight() > 0) {
// If it has been, we will search the view hierarchy for the view that is responsible for the extra space.
LinearLayout dialogLayout = findDialogLinearLayout(customView);
if (dialogLayout == null) {
// Could find it. Unexpected.
} else {
// Found it, now remove the height of the title area
View child = dialogLayout.getChildAt(0);
if (child != customView) {
// remove height
LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) child.getLayoutParams();
lp.height = 0;
child.setLayoutParams(lp);
} else {
// Could find it. Unexpected.
}
}
// Done with the listener
customView.getViewTreeObserver().removeGlobalOnLayoutListener(this);
}
}
});
// Show the dialog
if (show)
dialog.show();
}
/**
* Searches parents for a LinearLayout
*
* @param view to search the search from
* @return the first parent view that is a LinearLayout or null if none was found
*/
public static LinearLayout findDialogLinearLayout(View view) {
ViewParent parent = (ViewParent) view.getParent();
if (parent != null) {
if (parent instanceof LinearLayout) {
// Found it
return (LinearLayout) parent;
} else if (parent instanceof View) {
// Keep looking
return findDialogLinearLayout((View) parent);
}
}
// Couldn't find it
return null;
}
Here is an example of how it is used:
Dialog dialog = new AlertDialog.Builder(this)
.setView(yourCustomView)
.create();
showDialogWithNoTopSpace(yourCustomView, dialog, true);
If you are using this with a DialogFragment, override the DialogFragment's onCreateDialog
method. Then create and return your dialog like the first example above. The only change is that you should pass false as the 3rd parameter (show) so that it doesn't call show() on the dialog. The DialogFragment will handle that later.
Example:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = new AlertDialog.Builder(getContext())
.setView(yourCustomView)
.create();
showDialogWithNoTopSpace(yourCustomView, dialog, false);
return dialog;
}
As I test this further I'll be sure to update with any additional tweaks needed.
Use UIAppearance
protocol. Example for setting a font - create a category to extend UILabel
:
@interface UILabel (FontAppearance)
@property (nonatomic, copy) UIFont * appearanceFont UI_APPEARANCE_SELECTOR;
@end
@implementation UILabel (FontAppearance)
-(void)setAppearanceFont:(UIFont *)font {
if (font)
[self setFont:font];
}
-(UIFont *)appearanceFont {
return self.font;
}
@end
And its usage:
UILabel * appearanceLabel = [UILabel appearanceWhenContainedIn:UIAlertController.class, nil];
[appearanceLabel setAppearanceFont:[UIFont boldSystemFontOfSize:10]]; //for example
Tested and working with style UIAlertControllerStyleActionSheet
, but I guess it will work with UIAlertControllerStyleAlert
too.
P.S. Better check for class availability instead of iOS version:
if ([UIAlertController class]) {
// UIAlertController code (iOS 8)
} else {
// UIAlertView code (pre iOS 8)
}
It only works till 4000 byte, What if the clob is bigger than 4000 bytes then we use this
declare
v_clob_size clob;
begin
v_clob_size:= (DBMS_LOB.getlength(v_clob)) / 1024 / 1024;
DBMS_OUTPUT.put_line('CLOB Size ' || v_clob_size);
end;
or
select (DBMS_LOB.getlength(your_column_name))/1024/1024 from your_table
As ping
works, but telnet
to port 80
does not, the HTTP port 80
is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?).
You need to add some code to your python program, that handles the proxy, like described here:
I also tried this style for ionic hybrid app background. this is also having style for background blur effect.
.bg-image {
position: absolute;
background: url(../img/bglogin.jpg) no-repeat;
height: 100%;
width: 100%;
background-size: cover;
bottom: 0px;
margin: 0 auto;
background-position: 50%;
-webkit-filter: blur(5px);
-moz-filter: blur(5px);
-o-filter: blur(5px);
-ms-filter: blur(5px);
filter: blur(5px);
}
you can use ng-keydown , ng-keyup , ng-press such as this .
to triger a function :
<input type="text" ng-keypress="function()"/>
or if you have one condion such as when he press escape (27 is the key code for escape)
<form ng-keydown=" event.which=== 27?cancelSplit():0">
....
</form>
this works fine for me

This problem is beacouse your proyect is named serial.py and the library imported is name serial too , change the name and thats all.
Using dplyr:
library(dplyr)
# exclude ID column then get mean
DF %>%
transmute(ID,
Mean = rowMeans(select(., -ID)))
Or
# select the columns to include in mean
DF %>%
transmute(ID,
Mean = rowMeans(select(., C1:C3)))
# ID Mean
# 1 A 3.666667
# 2 B 4.333333
# 3 C 3.333333
# 4 D 4.666667
# 5 E 4.333333
In Addition to the above answers, there probably should be noted that there is a legacy way to implement the initialization. There is an interface called Initializable from the fxml library.
import javafx.fxml.Initializable;
class MyController implements Initializable {
@FXML private TableView<MyModel> tableView;
@Override
public void initialize(URL location, ResourceBundle resources) {
tableView.getItems().addAll(getDataFromSource());
}
}
Parameters:
location - The location used to resolve relative paths for the root object, or null if the location is not known.
resources - The resources used to localize the root object, or null if the root object was not localized.
And the note of the docs why the simple way of using @FXML public void initialize()
works:
NOTE
This interface has been superseded by automatic injection of location and resources properties into the controller. FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller. It is recommended that the injection approach be used whenever possible.

The same happened for me with eslint
module. EsLinter throw Parsing error: Invalid left-hand side in assignment expression
for await in second if statement.
if (condition_one) {
let result = await myFunction()
}
if (condition_two) {
let result = await myFunction() // eslint parsing error
}
As strange as it sounds what fixed this error was to add ; semicolon at the end of line where await occurred.
if (condition_one) {
let result = await myFunction();
}
if (condition_two) {
let result = await myFunction();
}
How do I loop through rows with a data reader in C#?
IDataReader.Read()
advances the reader to the next row in the resultset.
while(reader.Read()){
/* do whatever you'd like to do for each row. */
}
So, for each iteration of your loop, you'd do another loop, 0 to reader.FieldCount
, and call reader.GetValue(i)
for each field.
The bigger question is what kind of structure do you want to use to hold that data?
A true opposite to display: none
there is not (yet).
But display: unset
is very close and works in most cases.
From MDN (Mozilla Developer Network):
The unset CSS keyword is the combination of the initial and inherit keywords. Like these two other CSS-wide keywords, it can be applied to any CSS property, including the CSS shorthand all. This keyword resets the property to its inherited value if it inherits from its parent or to its initial value if not. In other words, it behaves like the inherit keyword in the first case and like the initial keyword in the second case.
Note also that display: revert
is currently being developed. See MDN for details.
if (android.os.Build.VERSION.SDK_INT >= 21) {
storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position], context.getTheme()));
} else {
storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position]));
}
This now works as they've made a release in version 23.2, as stated in this post. Quoting the official blogpost
This release brings an exciting new feature to the LayoutManager API: auto-measurement! This allows a RecyclerView to size itself based on the size of its contents. This means that previously unavailable scenarios, such as using WRAP_CONTENT for a dimension of the RecyclerView, are now possible. You’ll find all built in LayoutManagers now support auto-measurement.
Here's what worked for me:
#div {
display: flex;
justify-content: center;
}
#table {
align-self: center;
}
And this aligned it vertically and horizontally.
To specify more than one namespace to provide prefixes, use something like:
@javax.xml.bind.annotation.XmlSchema(
namespace = "urn:oecd:ties:cbc:v1",
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
xmlns ={@XmlNs(prefix="cbc", namespaceURI="urn:oecd:ties:cbc:v1"),
@XmlNs(prefix="iso", namespaceURI="urn:oecd:ties:isocbctypes:v1"),
@XmlNs(prefix="stf", namespaceURI="urn:oecd:ties:stf:v4")})

extending accepted answer with jquery
what if you want to add more canvas?, this jquery.each answer it
responsiveCanvas(); //first init
$(window).resize(function(){
responsiveCanvas(); //every resizing
stage.update(); //update the canvas, stage is object of easeljs
});
function responsiveCanvas(target){
$(canvas).each(function(e){
var parentWidth = $(this).parent().outerWidth();
var parentHeight = $(this).parent().outerHeight();
$(this).attr('width', parentWidth);
$(this).attr('height', parentHeight);
console.log(parentWidth);
})
}
it will do all the job for you
why we dont set the width
or the height
via css or style? because it will stretch your canvas instead of make it into expecting size
I'll take a stab at it:
/^[a-z](?:_?[a-z0-9]+)*$/i
Explained:
/
^ # match beginning of string
[a-z] # match a letter for the first char
(?: # start non-capture group
_? # match 0 or 1 '_'
[a-z0-9]+ # match a letter or number, 1 or more times
)* # end non-capture group, match whole group 0 or more times
$ # match end of string
/i # case insensitive flag
The non-capture group takes care of a) not allowing two _
's (it forces at least one letter or number per group) and b) only allowing the last char to be a letter or number.
Some test strings:
"a": match
"_": fail
"zz": match
"a0": match
"A_": fail
"a0_b": match
"a__b": fail
"a_1_c": match
This is not possible if you can't change your code. But I like dependency injection and Mockito supports it:
public class First {
@Resource
Second second;
public First() {
second = new Second();
}
public String doSecond() {
return second.doSecond();
}
}
Your test:
@RunWith(MockitoJUnitRunner.class)
public class YourTest {
@Mock
Second second;
@InjectMocks
First first = new First();
public void testFirst(){
when(second.doSecond()).thenReturn("Stubbed Second");
assertEquals("Stubbed Second", first.doSecond());
}
}
This is very nice and easy.
I believe that in the book class all \part and \chapter are set to start on a recto page.
from book.cls:
\newcommand\part{%
\if@openright
\cleardoublepage
\else
\clearpage
\fi
\thispagestyle{plain}%
\if@twocolumn
\onecolumn
\@tempswatrue
\else
\@tempswafalse
\fi
\null\vfil
\secdef\@part\@spart}
you should be able to renew that command, and something similar for the \chapter.
If you only care about modern browsers, a fixed header can be achieved much easier by using CSS transforms. Sounds odd, but works great:
document.getElementById("wrap").addEventListener("scroll", function(){
var translate = "translate(0,"+this.scrollTop+"px)";
this.querySelector("thead").style.transform = translate;
});
Support for CSS transforms is widely available except for Internet Explorer 8-.
Here is the full example for reference:
document.getElementById("wrap").addEventListener("scroll",function(){_x000D_
var translate = "translate(0,"+this.scrollTop+"px)";_x000D_
this.querySelector("thead").style.transform = translate;_x000D_
});

I would create a user control which holds a Label and a Text Box in it and simply create instances of that user control 'n' times. If you want to know a better way to do it and use properties to get access to the values of Label and Text Box from the user control, please let me know.
Simple way to do it would be:
int n = 4; // Or whatever value - n has to be global so that the event handler can access it
private void btnDisplay_Click(object sender, EventArgs e)
{
TextBox[] textBoxes = new TextBox[n];
Label[] labels = new Label[n];
for (int i = 0; i < n; i++)
{
textBoxes[i] = new TextBox();
// Here you can modify the value of the textbox which is at textBoxes[i]
labels[i] = new Label();
// Here you can modify the value of the label which is at labels[i]
}
// This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
for (int i = 0; i < n; i++)
{
this.Controls.Add(textBoxes[i]);
this.Controls.Add(labels[i]);
}
}
The code above assumes that you have a button btnDisplay
and it has a onClick
event assigned to btnDisplay_Click
event handler. You also need to know the value of n and need a way of figuring out where to place all controls. Controls should have a width and height specified as well.
To do it using a User Control simply do this.
Okay, first of all go and create a new user control and put a text box and label in it.
Lets say they are called txtSomeTextBox
and lblSomeLabel
. In the code behind add this code:
public string GetTextBoxValue()
{
return this.txtSomeTextBox.Text;
}
public string GetLabelValue()
{
return this.lblSomeLabel.Text;
}
public void SetTextBoxValue(string newText)
{
this.txtSomeTextBox.Text = newText;
}
public void SetLabelValue(string newText)
{
this.lblSomeLabel.Text = newText;
}
Now the code to generate the user control will look like this (MyUserControl is the name you have give to your user control):
private void btnDisplay_Click(object sender, EventArgs e)
{
MyUserControl[] controls = new MyUserControl[n];
for (int i = 0; i < n; i++)
{
controls[i] = new MyUserControl();
controls[i].setTextBoxValue("some value to display in text");
controls[i].setLabelValue("some value to display in label");
// Now if you write controls[i].getTextBoxValue() it will return "some value to display in text" and controls[i].getLabelValue() will return "some value to display in label". These value will also be displayed in the user control.
}
// This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
for (int i = 0; i < n; i++)
{
this.Controls.Add(controls[i]);
}
}
Of course you can create more methods in the usercontrol to access properties and set them. Or simply if you have to access a lot, just put in these two variables and you can access the textbox and label directly:
public TextBox myTextBox;
public Label myLabel;
In the constructor of the user control do this:
myTextBox = this.txtSomeTextBox;
myLabel = this.lblSomeLabel;
Then in your program if you want to modify the text value of either just do this.
control[i].myTextBox.Text = "some random text"; // Same applies to myLabel
Hope it helped :)
You should do something like this to help you debug
$sql = "insert into blah values ('$myVar')";
echo $sql;
You will probably find that the single quote is escaped with a backslash in the working query. This might have been done automatically by PHP via the magic_quotes_gpc setting, or maybe you did it yourself in some other part of the code (addslashes and stripslashes might be functions to look for).

For NetBeans 8+ on Windows 10 there's a definitive bug with duplicate classes error which is being solved by cleaning the cache at
C:\Users\<user>\AppData\Local\NetBeans\Cache
.
If you want a full-featured, yet succinct approach to handling real-world data structures which are often nested, and can even contain cycles, I recommend looking at the remap utility from the boltons utility package.
After pip install boltons
or copying iterutils.py into your project, just do:
from boltons.iterutils import remap
drop_falsey = lambda path, key, value: bool(value)
clean = remap(metadata, visit=drop_falsey)
This page has many more examples, including ones working with much larger objects from Github's API.
It's pure-Python, so it works everywhere, and is fully tested in Python 2.7 and 3.3+. Best of all, I wrote it for exactly cases like this, so if you find a case it doesn't handle, you can bug me to fix it right here.
~/In_ProjectDirectory $ g++ coordin_main.cpp coordin_func.cpp coordin.h
~/In_ProjectDirectory $ ./a.out
... Worked!!
Using Linux Mint with Geany IDE
When I saved each file to the same directory, one file was not saved correctly within the directory; the coordin.h file. So, rechecked and it was saved there as coordin.h, and not incorrectly as -> coordin.h.gch. The little stuff. Arg!!
You can get a columns value by doing this
rows["ColumnName"]
You will also have to cast to the appropriate type.
output += (string)rows["ColumnName"]

As per current versions, Android doesn't ask for permission to interact with the internet but you can add the below code which will help for users using older versions Just add these in AndroidManifest
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
c_str() converts a C++ string into a C-style string which is essentially a null terminated array of bytes. You use it when you want to pass a C++ string into a function that expects a C-style string (e.g. a lot of the Win32 API, POSIX style functions, etc).
Since jQuery.get is just a shorthand for jQuery.ajax, another way would be to use the latter one's context
option, as stated in the documentation:
The
this
reference within all callbacks is the object in the context option passed to$.ajax
in the settings; if context is not specified, this is a reference to the Ajax settings themselves.
So you would use
$.ajax('http://www.example.org', {
dataType: 'xml',
data: {'a':1,'b':2,'c':3},
context: {
url: 'http://www.example.org'
}
}).done(function(xml) {alert(this.url});
Python 2.5 includes an uuid implementation which (in at least one version) needs the mac address. You can import the mac finding function into your own code easily:
from uuid import getnode as get_mac
mac = get_mac()
The return value is the mac address as 48 bit integer.

First Suggestion:
Create a Javascript Variable that will reference the button clicked. Lets call it buttonIndex
<input type="submit" onclick="buttonIndex=0;" name="save" value="Save" />
<input type="submit" onclick="buttonIndex=1;" name="saveAndAdd" value="Save and add another" />
Now, you can access that value. 0 means the save button was clicked, 1 means the saveAndAdd Button was clicked.
Second Suggestion
The way I would handle this is to create two JS functions that handle each of the two buttons.
First, make sure your form has a valid ID. For this example, I'll say the ID is "myForm"
change
<input type="submit" name="save" value="Save" />
<input type="submit" name="saveAndAdd" value="Save and add another" />
to
<input type="submit" onclick="submitFunc();return(false);" name="save" value="Save" />
<input type="submit" onclick="submitAndAddFunc();return(false);" name="saveAndAdd" value="Save and add
the return(false) will prevent your form submission from actually processing, and call your custom functions, where you can submit the form later on.
Then your functions will work something like this...
function submitFunc(){
// Do some asyncrhnous stuff, that will later on submit the form
if (okToSubmit) {
document.getElementById('myForm').submit();
}
}
function submitAndAddFunc(){
// Do some asyncrhnous stuff, that will later on submit the form
if (okToSubmit) {
document.getElementById('myForm').submit();
}
}
I had same question and I found this answer on this website.
And I changed it just a little bit (the curl_close at last line)
$username = 'myuser';
$password = 'mypass';
$loginUrl = 'http://www.example.com/login/';
//init curl
$ch = curl_init();
//Set the URL to work with
curl_setopt($ch, CURLOPT_URL, $loginUrl);
// ENABLE HTTP POST
curl_setopt($ch, CURLOPT_POST, 1);
//Set the post parameters
curl_setopt($ch, CURLOPT_POSTFIELDS, 'user='.$username.'&pass='.$password);
//Handle cookies for the login
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
//Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL
//not to print out the results of its query.
//Instead, it will return the results as a string return value
//from curl_exec() instead of the usual true/false.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//execute the request (the login)
$store = curl_exec($ch);
//the login is now done and you can continue to get the
//protected content.
//set the URL to the protected file
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/protected/download.zip');
//execute the request
$content = curl_exec($ch);
curl_close($ch);
//save the data to disk
file_put_contents('~/download.zip', $content);
I think this was what you were looking for.Am I right?
And one useful related question. About how to keep a session alive in cUrl: https://stackoverflow.com/a/13020494/2226796
If you want to get the strings separated by the ,
you can use
string b = a.Split(',')[0];
In the sense you mean — no, you cannot.
You can declare a va_arg
function like
void my_func(char* format, ...);
, but you'll need to pass some kind of information about number of variables and their types in the first argument — like printf()
does.
I think this solution uses less code and is easy to understand even for newbie.
For string field in struct, you can use pointer and reassigning the string to that pointer will be straightforward and simpler.
Define definition of struct:
typedef struct {
int number;
char *name;
char *address;
char *birthdate;
char gender;
} Patient;
Initialize variable with type of that struct:
Patient patient;
patient.number = 12345;
patient.address = "123/123 some road Rd.";
patient.birthdate = "2020/12/12";
patient.gender = "M";
It is that simple. Hope this answer helps many developers.
You should use html():
$(document).ready(function(){
$("#date").html('<span>'+$("#date").text().substring(0, 2) + '</span><br />'+$("#date").text().substring(3));
});
You need to escape the .
as "0\.49"
.
A .
is a regex meta-character to match any character(except newline). To match a literal period, you need to escape it.
.circle {
border-radius: 50%;
width: 500px;
height: 500px;
background: red;
}
<div class="circle"></div>

I like to use double quotes around strings that are used for interpolation or that are natural language messages, and single quotes for small symbol-like strings, but will break the rules if the strings contain quotes, or if I forget. I use triple double quotes for docstrings and raw string literals for regular expressions even if they aren't needed.
For example:
LIGHT_MESSAGES = {
'English': "There are %(number_of_lights)s lights.",
'Pirate': "Arr! Thar be %(number_of_lights)s lights."
}
def lights_message(language, number_of_lights):
"""Return a language-appropriate string reporting the light count."""
return LIGHT_MESSAGES[language] % locals()
def is_pirate(message):
"""Return True if the given message sounds piratical."""
return re.search(r"(?i)(arr|avast|yohoho)!", message) is not None
Have a look at the Python tutorial on tuples:
A special problem is the construction of tuples containing 0 or 1 items: the syntax has some extra quirks to accommodate these. Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses). Ugly, but effective. For example:
>>> empty = () >>> singleton = 'hello', # <-- note trailing comma >>> len(empty) 0 >>> len(singleton) 1 >>> singleton ('hello',)
If you put just a pair of parentheses around your string object, they will only turn that expression into an parenthesized expression (emphasis added):
A parenthesized expression list yields whatever that expression list yields: if the list contains at least one comma, it yields a tuple; otherwise, it yields the single expression that makes up the expression list.
An empty pair of parentheses yields an empty tuple object. Since tuples are immutable, the rules for literals apply (i.e., two occurrences of the empty tuple may or may not yield the same object).
Note that tuples are not formed by the parentheses, but rather by use of the comma operator. The exception is the empty tuple, for which parentheses are required — allowing unparenthesized “nothing” in expressions would cause ambiguities and allow common typos to pass uncaught.
That is (assuming Python 2.7),
a = 'Quattro TT'
print tuple(a) # <-- you create a tuple from a sequence
# (which is a string)
print tuple([a]) # <-- you create a tuple from a sequence
# (which is a list containing a string)
print tuple(list(a)) # <-- you create a tuple from a sequence
# (which you create from a string)
print (a,) # <-- you create a tuple containing the string
print (a) # <-- it's just the string wrapped in parentheses
The output is as expected:
('Q', 'u', 'a', 't', 't', 'r', 'o', ' ', 'T', 'T')
('Quattro TT',)
('Q', 'u', 'a', 't', 't', 'r', 'o', ' ', 'T', 'T')
('Quattro TT',)
Quattro TT
To add some notes on the print statement. When you try to create a single-element tuple as part of a print statement in Python 2.7 (as in print (a,)
) you need to use the parenthesized form, because the trailing comma of print a,
would else be considered part of the print statement and thus cause the newline to be suppressed from the output and not a tuple being created:
A '\n' character is written at the end, unless the print statement ends with a comma.
In Python 3.x most of the above usages in the examples would actually raise SyntaxError
, because in Python 3 print
turns into a function (you need to add an extra pair of parentheses).
But especially this may cause confusion:
print (a,) # <-- this prints a tuple containing `a` in Python 2.x
# but only `a` in Python 3.x
In addition to bchhun's great answer, if you want absoulte positioning, you can do this
var options = {
placement: function (context, source) {
setTimeout(function () {
$(context).css('top',(source.getBoundingClientRect().top+ 500) + 'px')
},0)
return "top";
},
trigger: "click"
};
$(".infopoint").popover(options);
Assuming it actually is a symlink,
$ rm -d symlink
It should figure it out, but since it can't we enable the latent code that was intended for another case that no longer exists but happens to do the right thing here.
You need to stringify the object.
fs.writeFileSync('../data/phraseFreqs.json', JSON.stringify(output));
The link you gave does actually describe the differences, but it's buried at the bottom of the page:
http://www.cplusplus.com/reference/cstdio/fopen/
Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.
The conversion could be to normalize \r\n
to \n
(or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.
You can use Intent
Intent mIntent = new Intent(FirstActivity.this, SecondActivity.class);
mIntent.putExtra("data", data);
startActivity(mIntent);
Another way could be using singleton pattern also:
public class DataHolder {
private static DataHolder dataHolder;
private List<Model> dataList;
public void setDataList(List<Model>dataList) {
this.dataList = dataList;
}
public List<Model> getDataList() {
return dataList;
}
public synchronized static DataHolder getInstance() {
if (dataHolder == null) {
dataHolder = new DataHolder();
}
return dataHolder;
}
}
From your FirstActivity
private List<Model> dataList = new ArrayList<>();
DataHolder.getInstance().setDataList(dataList);
On SecondActivity
private List<Model> dataList = DataHolder.getInstance().getDataList();
After a quick google:
__STDC__
and __STDC_VERSION__
, see here
& <-- verifies both operands
&& <-- stops evaluating if the first operand evaluates to false since the result will be false
(x != 0) & (1/x > 1)
<-- this means evaluate (x != 0)
then evaluate (1/x > 1)
then do the &. the problem is that for x=0 this will throw an exception.
(x != 0) && (1/x > 1)
<-- this means evaluate (x != 0)
and only if this is true then evaluate (1/x > 1)
so if you have x=0 then this is perfectly safe and won't throw any exception if (x != 0) evaluates to false the whole thing directly evaluates to false without evaluating the (1/x > 1)
.
EDIT:
exprA | exprB
<-- this means evaluate exprA
then evaluate exprB
then do the |
.
exprA || exprB
<-- this means evaluate exprA
and only if this is false
then evaluate exprB
and do the ||
.
Here is a simpler method (hack) that gives you back the setdefaultencoding()
function that was deleted from sys
:
import sys
# sys.setdefaultencoding() does not exist, here!
reload(sys) # Reload does the trick!
sys.setdefaultencoding('UTF8')
(Note for Python 3.4+: reload()
is in the importlib
library.)
This is not a safe thing to do, though: this is obviously a hack, since sys.setdefaultencoding()
is purposely removed from sys
when Python starts. Reenabling it and changing the default encoding can break code that relies on ASCII being the default (this code can be third-party, which would generally make fixing it impossible or dangerous).
XmlTextWriter xmlw = new XmlTextWriter(@"C:\WINDOWS\Temp\exm.xml",System.Text.Encoding.UTF8);
xmlw.WriteStartDocument();
xmlw.WriteStartElement("examtimes");
xmlw.WriteStartElement("Starttime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Changetime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Endtime");
xmlw.WriteString(DateTime.Now.AddHours(1).ToString());
xmlw.WriteEndElement();
xmlw.WriteEndElement();
xmlw.WriteEndDocument();
xmlw.Close();
XmlDocument doc = new XmlDocument();
doc.Load(@"C:\WINDOWS\Temp\exm.xml");
XmlNode root = doc.DocumentElement["Starttime"];
root.FirstChild.InnerText = "First";
XmlNode root1 = doc.DocumentElement["Changetime"];
root1.FirstChild.InnerText = "Second";
doc.Save(@"C:\WINDOWS\Temp\exm.xml");
Try this. It's C# code.
A useful application for : is if you're only interested in using parameter expansions for their side-effects rather than actually passing their result to a command. In that case you use the PE as an argument to either : or false depending upon whether you want an exit status of 0 or 1. An example might be : "${var:=$1}"
. Since :
is a builtin it should be pretty fast.
You need to load the URL Helper in order to use base_url()
. In your controller, do:
$this->load->helper('url');
Then in your view you can do:
echo base_url();
I can assure you that raw speed ultimately lies in the non-standard use of Indexes for blazing speed using large tables.
Using C# 6.0 (which allows expression bodied functions and null propagation), for LINQ to Objects, it can be done in a single line like this (also checking for null):
public static bool ContainsInsensitive(this string str, string value) => str?.IndexOf(value, StringComparison.OrdinalIgnoreCase) >= 0;
I´ve had the same problem with pages that:
To solve the problem (using php), I used utf8_encode()
or htmlentities()
on the source data. Both worked, I have used them in different projects.
Remember that when you use an instead trigger, it will not commit the insert unless you specifically tell it to in the trigger. Instead of really means do this instead of what you normally do, so none of the normal insert actions would happen.
if( strpos( $url, "#" ) === false ) echo "NO HASH !";
else echo "HASH IS: #".explode( "#", $url )[1]; // arrays are indexed from 0
Or in "old" PHP you must pre-store the exploded to access the array:
$exploded_url = explode( "#", $url ); $exploded_url[1];
var forms = document.getElementsByTagName('form'); //get all forms on the site
for (var i = 0; i < forms.length; i++) { //to each form...
forms[i].addEventListener( // add a "listener"
'submit', // for an on-submit "event"
function () { //add a submit pre-processing function:
var input_name = "fragment"; // name form will use to send the fragment
// Try search whether we already done this or not
// in current form, find every <input ... name="fragment" ...>
var hiddens = form.querySelectorAll('[name="' + input_name + '"]');
if (hiddens.length < 1) { // if not there yet
//create an extra input element
var hidden = document.createElement("input");
//set it to hidden so it doesn't break view
hidden.setAttribute('type', 'hidden');
//set a name to get by it in PHP
hidden.setAttribute('name', input_name);
this.appendChild(hidden); //append it to the current form
} else {
var hidden = hiddens[0]; // use an existing one if already there
}
//set a value of #HASH - EVERY TIME, so we get the MOST RECENT #hash :)
hidden.setAttribute('value', window.location.hash);
}
);
}
Depending on your form
's method
attribute you get this hash in PHP by:
$_GET['fragment']
or $_POST['fragment']
Possible returns: 1. ""
[empty string] (no hash) 2. whole hash INCLUDING the #
[hash] sign (because we've used the window.location.hash
in JavaScript which just works that way :) )
...(not while considering regular HTTP requests)...
...Hope this helped :)
I thought I had misunderstood but I was right. In this scenario, it will be ActiveWorkbook.Path
But the main issue was not here. The problem was with these 2 lines of code
strFile = Dir(strPath & "*.csv")
Which should have written as
strFile = Dir(strPath & "\*.csv")
and
With .QueryTables.Add(Connection:="TEXT;" & strPath & strFile, _
Which should have written as
With .QueryTables.Add(Connection:="TEXT;" & strPath & "\" & strFile, _
This warning comes when you don't add a key to your list items.As per react js Docs -
Keys help React identify which items have changed, are added, or are removed. Keys should be given to the elements inside the array to give the elements a stable identity:
const numbers = [1, 2, 3, 4, 5];
const listItems = numbers.map((number) =>
<li key={number.toString()}>
{number}
</li>
);
The best way to pick a key is to use a string that uniquely identifies a list item among its siblings. Most often you would use IDs from your data as keys:
const todoItems = todos.map((todo) =>
<li key={todo.id}>
{todo.text}
</li>
);
When you don’t have stable IDs for rendered items, you may use the item index as a key as a last resort
const todoItems = todos.map((todo, index) =>
// Only do this if items have no stable IDs
<li key={index}>
{todo.text}
</li>

Blowfish is not a hashing algorithm. It's an encryption algorithm. What that means is that you can encrypt something using blowfish, and then later on you can decrypt it back to plain text.
SHA512 is a hashing algorithm. That means that (in theory) once you hash the input you can't get the original input back again.
They're 2 different things, designed to be used for different tasks. There is no 'correct' answer to "is blowfish better than SHA512?" You might as well ask "are apples better than kangaroos?"

Based on @vdegenne 's answer... how to strip:
Single trailing slash:
theString.replace(/\/$/, '');
Single or consecutive trailing slashes:
theString.replace(/\/+$/g, '');
Single leading slash:
theString.replace(/^\//, '');
Single or consecutive leading slashes:
theString.replace(/^\/+/g, '');
Single leading and trailing slashes:
theString.replace(/^\/|\/$/g, '')
Single or consecutive leading and trailing slashes:
theString.replace(/^\/+|\/+$/g, '')
To handle both slashes and backslashes, replace instances of \/
with [\\/]
You can do this with JQueryUI:
$('a').mouseenter(function(){
$(this).animate({
color: '#ff0000'
}, 1000);
}).mouseout(function(){
$(this).animate({
color: '#000000'
}, 1000);
});
Briefly, with more detail below,
window
is the execution context and global object for that context's JavaScriptdocument
contains the DOM, initialized by parsing HTMLscreen
describes the physical display's full screenSee W3C and Mozilla references for details about these objects. The most basic relationship among the three is that each browser tab has its own window
, and a window
has window.document
and window.screen
properties. The browser tab's window
is the global context, so document
and screen
refer to window.document
and window.screen
. More details about the three objects are below, following Flanagan's JavaScript: Definitive Guide.
window
Each browser tab has its own top-level window
object. Each <iframe>
(and deprecated <frame>
) element has its own window
object too, nested within a parent window. Each of these windows gets its own separate global object. window.window
always refers to window
, but window.parent
and window.top
might refer to enclosing windows, giving access to other execution contexts. In addition to document
and screen
described below, window
properties include
setTimeout()
and setInterval()
binding event handlers to a timerlocation
giving the current URLhistory
with methods back()
and forward()
giving the tab's mutable historynavigator
describing the browser softwaredocument
Each window
object has a document
object to be rendered. These objects get confused in part because HTML elements are added to the global object when assigned a unique id. E.g., in the HTML snippet
<body>
<p id="holyCow"> This is the first paragraph.</p>
</body>
the paragraph element can be referenced by any of the following:
window.holyCow
or window["holyCow"]
document.getElementById("holyCow")
document.querySelector("#holyCow")
document.body.firstChild
document.body.children[0]
screen
The window
object also has a screen
object with properties describing the physical display:
screen properties width
and height
are the full screen
screen properties availWidth
and availHeight
omit the toolbar
The portion of a screen displaying the rendered document is the viewport in JavaScript, which is potentially confusing because we call an application's portion of the screen a window when talking about interactions with the operating system. The getBoundingClientRect()
method of any document
element will return an object with top
, left
, bottom
, and right
properties describing the location of the element in the viewport.
For date:
#!/usr/bin/ruby -w
date = Time.new
#set 'date' equal to the current date/time.
date = date.day.to_s + "/" + date.month.to_s + "/" + date.year.to_s
#Without this it will output 2015-01-10 11:33:05 +0000; this formats it to display DD/MM/YYYY
puts date
#output the date
The above will display, for example, 10/01/15
And for time
time = Time.new
#set 'time' equal to the current time.
time = time.hour.to_s + ":" + time.min.to_s
#Without this it will output 2015-01-10 11:33:05 +0000; this formats it to display hour and minute
puts time
#output the time
The above will display, for example, 11:33
Then to put it together, add to the end:
puts date + " " + time
- It is a very easy to use method in C++11.
- We can use std::chrono::high_resolution_clock from header
- We can write a method to print the method execution time in a much readable form.
For example, to find the all the prime numbers between 1 and 100 million, it takes approximately 1 minute and 40 seconds. So the execution time get printed as:
Execution Time: 1 Minutes, 40 Seconds, 715 MicroSeconds, 715000 NanoSeconds
The code is here:
#include <iostream>
#include <chrono>
using namespace std;
using namespace std::chrono;
typedef high_resolution_clock Clock;
typedef Clock::time_point ClockTime;
void findPrime(long n, string file);
void printExecutionTime(ClockTime start_time, ClockTime end_time);
int main()
{
long n = long(1E+8); // N = 100 million
ClockTime start_time = Clock::now();
// Write all the prime numbers from 1 to N to the file "prime.txt"
findPrime(n, "C:\\prime.txt");
ClockTime end_time = Clock::now();
printExecutionTime(start_time, end_time);
}
void printExecutionTime(ClockTime start_time, ClockTime end_time)
{
auto execution_time_ns = duration_cast<nanoseconds>(end_time - start_time).count();
auto execution_time_ms = duration_cast<microseconds>(end_time - start_time).count();
auto execution_time_sec = duration_cast<seconds>(end_time - start_time).count();
auto execution_time_min = duration_cast<minutes>(end_time - start_time).count();
auto execution_time_hour = duration_cast<hours>(end_time - start_time).count();
cout << "\nExecution Time: ";
if(execution_time_hour > 0)
cout << "" << execution_time_hour << " Hours, ";
if(execution_time_min > 0)
cout << "" << execution_time_min % 60 << " Minutes, ";
if(execution_time_sec > 0)
cout << "" << execution_time_sec % 60 << " Seconds, ";
if(execution_time_ms > 0)
cout << "" << execution_time_ms % long(1E+3) << " MicroSeconds, ";
if(execution_time_ns > 0)
cout << "" << execution_time_ns % long(1E+6) << " NanoSeconds, ";
}
This will be possible with setiosflags(ios::showpoint).
dict((el,0) for el in a)
will work well.
Python 2.7 and above also support dict comprehensions. That syntax is {el:0 for el in a}
.
I just discovered that:
new File("/sdcard/").listFiles()
returns null if you do not have:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
set in your AndroidManifest.xml file.
If you are using base graphics (i.e. not lattice/ grid graphics), then you can mimic MATLAB's hold on feature by using the points/lines/polygons functions to add additional details to your plots without starting a new plot. In the case of a multiplot layout, you can use par(mfg=...)
to pick which plot you add things to.
I can't comment on the post that is the closest #5717133, but below is the way I figured out how to get @tom-gullen regex working.
/^(https?:\/\/)?((([a-z\d]([a-z\d-]*[a-z\d])*)\.)+[a-z]{2,}|((\d{1,3}\.){3}\d{1,3}))(\:\d+)?(\/[-a-z\d%_.~+]*)*(\?[;&a-z\d%_.~+=-]*)?(\#[-a-z\d_]*)?$/i
This will work:
>>> t = [1,1,2,2,3,3,4,5]
>>> print list(set(t))
[1,2,3,4,5]
However, if you have used "list" or "set" as a variable name you will get the:
TypeError: 'set' object is not callable
eg:
>>> set = [1,1,2,2,3,3,4,5]
>>> print list(set(set))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable
Same error will occur if you have used "list" as a variable name.
My personal opinion is to use what makes sense in the context. Personally I almost never use for
for array traversal. I use it for other types of iteration, but foreach
is just too easy... The time difference is going to be minimal in most cases.
The big thing to watch for is:
for ($i = 0; $i < count($array); $i++) {
That's an expensive loop, since it calls count on every single iteration. So long as you're not doing that, I don't think it really matters...
As for the reference making a difference, PHP uses copy-on-write, so if you don't write to the array, there will be relatively little overhead while looping. However, if you start modifying the array within the array, that's where you'll start seeing differences between them (since one will need to copy the entire array, and the reference can just modify inline)...
As for the iterators, foreach
is equivalent to:
$it->rewind();
while ($it->valid()) {
$key = $it->key(); // If using the $key => $value syntax
$value = $it->current();
// Contents of loop in here
$it->next();
}
As far as there being faster ways to iterate, it really depends on the problem. But I really need to ask, why? I understand wanting to make things more efficient, but I think you're wasting your time for a micro-optimization. Remember, Premature Optimization Is The Root Of All Evil
...
Edit: Based upon the comment, I decided to do a quick benchmark run...
$a = array();
for ($i = 0; $i < 10000; $i++) {
$a[] = $i;
}
$start = microtime(true);
foreach ($a as $k => $v) {
$a[$k] = $v + 1;
}
echo "Completed in ", microtime(true) - $start, " Seconds\n";
$start = microtime(true);
foreach ($a as $k => &$v) {
$v = $v + 1;
}
echo "Completed in ", microtime(true) - $start, " Seconds\n";
$start = microtime(true);
foreach ($a as $k => $v) {}
echo "Completed in ", microtime(true) - $start, " Seconds\n";
$start = microtime(true);
foreach ($a as $k => &$v) {}
echo "Completed in ", microtime(true) - $start, " Seconds\n";
And the results:
Completed in 0.0073502063751221 Seconds
Completed in 0.0019769668579102 Seconds
Completed in 0.0011849403381348 Seconds
Completed in 0.00111985206604 Seconds
So if you're modifying the array in the loop, it's several times faster to use references...
And the overhead for just the reference is actually less than copying the array (this is on 5.3.2)... So it appears (on 5.3.2 at least) as if references are significantly faster...
You can join to the same table on the fields that would be duplicated and then anti-join on the id field. Select the id field from the first table alias (tn1) and then use the array_agg function on the id field of the second table alias. Finally, for the array_agg function to work properly, you will group the results by the tn1.id field. This will produce a result set that contains the the id of a record and an array of all the id's that fit the join conditions.
select tn1.id,
array_agg(tn2.id) as duplicate_entries,
from table_name tn1 join table_name tn2 on
tn1.year = tn2.year
and tn1.sid = tn2.sid
and tn1.user_id = tn2.user_id
and tn1.cid = tn2.cid
and tn1.id <> tn2.id
group by tn1.id;
Obviously, id's that will be in the duplicate_entries array for one id, will also have their own entries in the result set. You will have to use this result set to decide which id you want to become the source of 'truth.' The one record that shouldn't get deleted. Maybe you could do something like this:
with dupe_set as (
select tn1.id,
array_agg(tn2.id) as duplicate_entries,
from table_name tn1 join table_name tn2 on
tn1.year = tn2.year
and tn1.sid = tn2.sid
and tn1.user_id = tn2.user_id
and tn1.cid = tn2.cid
and tn1.id <> tn2.id
group by tn1.id
order by tn1.id asc)
select ds.id from dupe_set ds where not exists
(select de from unnest(ds.duplicate_entries) as de where de < ds.id)
Selects the lowest number ID's that have duplicates (assuming the ID is increasing int PK). These would be the ID's that you would keep around.
There is no show
event in js - you need to bind your button either to the click
event:
$('#id').on('click', function (e) {
//your awesome code here
})
Mind that if your button is inside a form
, you may prefer to bind the whole form to the submit
event.
There's no single method to do that. Use this:
@SuppressWarnings("unchecked")
public static <T extends Comparable> List<T> asSortedList(Collection<T> collection) {
T[] array = collection.toArray(
(T[])new Comparable[collection.size()]);
Arrays.sort(array);
return Arrays.asList(array);
}
My problem was that I had setup an @ManyToOne
relationship. Maybe if the answers above don't fix your problem you might want to check the relationship that was mentioned in the error message.
Forget everything. Just use the appcompat library downloaded using the Android Studio. It has all the missing definitions. No matter whether you are using in Eclipse or not.
Why not use the following: (from Draw custom Back button on iPhone Navigation Bar)
// Add left
UINavigationItem *previousItem = [[UINavigationItem alloc] initWithTitle:@"Back title"];
UINavigationItem *currentItem = [[UINavigationItem alloc] initWithTitle:@"Main Title"];
[self.navigationController.navigationBar setItems:[NSArray arrayWithObjects:previousItem, currentItem, nil] animated:YES];
// set the delegate to self
[self.navigationController.navigationBar setDelegate:self];
x86
means Intel 80x86 compatible. This used to include the 8086, a 16-bit only processor. Nowadays it roughly means any CPU with a 32-bit Intel compatible instruction set (usually anything from Pentium onwards). Never read x32
being used.
x64
means a CPU that is x86
compatible but has a 64-bit mode as well (most often the 64-bit instruction set as introduced by AMD is meant; Intel's idea of a 64-bit mode was totally stupid and luckily Intel admitted that and is now using AMDs variant).
So most of the time you can simplify it this way: x86
is Intel compatible in 32-bit mode, x64
is Intel compatible in 64-bit mode.
I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:
1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)
2: Run your formula
3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank
4: Replace All
Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.
Use this snippet
import os
import requests
url = 'http://host:port/endpoint'
with open(path_img, 'rb') as img:
name_img= os.path.basename(path_img)
files= {'image': (name_img,img,'multipart/form-data',{'Expires': '0'}) }
with requests.Session() as s:
r = s.post(url,files=files)
print(r.status_code)
Are you looking for this?
ContactNumbers = new List<ContactNumber>(){ new ContactNumber("555-5555"),
new ContactNumber("555-1234"),
new ContactNumber("555-5678") };
static __attribute__ ((noinline)) void foo()
{
}
This is what worked for me.
This is how it should be done in typescript:
(new Date()).valueOf() - (new Date("2013-02-20T12:01:04.753Z")).valueOf()
Better readability:
var eventStartTime = new Date(event.startTime);
var eventEndTime = new Date(event.endTime);
var duration = eventEndTime.valueOf() - eventStartTime.valueOf();
This will work:
for i in range(len(a)):
a[i] -= 13
There is a shorter alternative to the previous answer. SVG Elements can also be grouped by nesting svg elements:
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
<svg x="10">
<rect x="10" y="10" height="100" width="100" style="stroke:#ff0000;fill: #0000ff"/>
</svg>
<svg x="200">
<rect x="10" y="10" height="100" width="100" style="stroke:#009900;fill: #00cc00"/>
</svg>
</svg>
The two rectangles are identical (apart from the colors), but the parent svg elements have different x values.
