You can add one of the Java path to PATH variable using the following command.
export PATH=$PATH:/usr/java/jre1.6.0_24/bin/
You can add this line to .bashrc file in your home directory. Adding this to .bashrc will ensure everytime you open bash it will be PATH variable is updated.
Use fabs() instead of abs(), it's the same but for floats instead of integers.
Maybe it helps others, myself I had
session_regenerate_id(false);
I removed it and all ok!
after login was ok... ouch!
onMeasure()
is your opportunity to tell Android how big you want your custom view to be dependent the layout constraints provided by the parent; it is also your custom view's opportunity to learn what those layout constraints are (in case you want to behave differently in a match_parent
situation than a wrap_content
situation). These constraints are packaged up into the MeasureSpec
values that are passed into the method. Here is a rough correlation of the mode values:
layout_width
or layout_height
value was set to a specific value. You should probably make your view this size. This can also get triggered when match_parent
is used, to set the size exactly to the parent view (this is layout dependent in the framework).layout_width
or layout_height
value was set to match_parent
or wrap_content
where a maximum size is needed (this is layout dependent in the framework), and the size of the parent dimension is the value. You should not be any larger than this size.layout_width
or layout_height
value was set to wrap_content
with no restrictions. You can be whatever size you would like. Some layouts also use this callback to figure out your desired size before determine what specs to actually pass you again in a second measure request.The contract that exists with onMeasure()
is that setMeasuredDimension()
MUST be called at the end with the size you would like the view to be. This method is called by all the framework implementations, including the default implementation found in View
, which is why it is safe to call super
instead if that fits your use case.
Granted, because the framework does apply a default implementation, it may not be necessary for you to override this method, but you may see clipping in cases where the view space is smaller than your content if you do not, and if you lay out your custom view with wrap_content
in both directions, your view may not show up at all because the framework doesn't know how large it is!
Generally, if you are overriding View
and not another existing widget, it is probably a good idea to provide an implementation, even if it is as simple as something like this:
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int desiredWidth = 100;
int desiredHeight = 100;
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthSize = MeasureSpec.getSize(widthMeasureSpec);
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightSize = MeasureSpec.getSize(heightMeasureSpec);
int width;
int height;
//Measure Width
if (widthMode == MeasureSpec.EXACTLY) {
//Must be this size
width = widthSize;
} else if (widthMode == MeasureSpec.AT_MOST) {
//Can't be bigger than...
width = Math.min(desiredWidth, widthSize);
} else {
//Be whatever you want
width = desiredWidth;
}
//Measure Height
if (heightMode == MeasureSpec.EXACTLY) {
//Must be this size
height = heightSize;
} else if (heightMode == MeasureSpec.AT_MOST) {
//Can't be bigger than...
height = Math.min(desiredHeight, heightSize);
} else {
//Be whatever you want
height = desiredHeight;
}
//MUST CALL THIS
setMeasuredDimension(width, height);
}
Hope that Helps.
Since Java 7 you can do the same with Files.newBufferedWriter
a little more succinctly:
Path logFile = Paths.get("/tmp/example.txt");
try (BufferedWriter writer = Files.newBufferedWriter(logFile, StandardCharsets.UTF_8)) {
writer.write("Hello World!");
// ...
}
The dword ptr
part is called a size directive. This page explains them, but it wasn't possible to direct-link to the correct section.
Basically, it means "the size of the target operand is 32 bits", so this will bitwise-AND the 32-bit value at the address computed by taking the contents of the ebp
register and subtracting four with 0.
See the first answer to Accessing a matrix element in the "Mat" object (not the CvMat object) in OpenCV C++
Then just loop over all the elements in cout << M.at<double>(0,0);
rather than just 0,0
Or better still with the C++ interface:
cv::Mat M;
cout << "M = " << endl << " " << M << endl << endl;
The answer of Uttam didnt work for me. I just got null when I do:
Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);
In my case, bitmapdata only has the buffer of the pixels, so it is imposible for the function decodeByteArray to guess which the width, the height and the color bits use. So I tried this and it worked:
//Create bitmap with width, height, and 4 bytes color (RGBA)
Bitmap bmp = Bitmap.createBitmap(imageWidth, imageHeight, Bitmap.Config.ARGB_8888);
ByteBuffer buffer = ByteBuffer.wrap(bitmapdata);
bmp.copyPixelsFromBuffer(buffer);
Check https://developer.android.com/reference/android/graphics/Bitmap.Config.html for different color options

Three ways to pass model data to partial view (there may be more)
This is view page
Method One Populate at view
@{
PartialViewTestSOl.Models.CountryModel ctry1 = new PartialViewTestSOl.Models.CountryModel();
ctry1.CountryName="India";
ctry1.ID=1;
PartialViewTestSOl.Models.CountryModel ctry2 = new PartialViewTestSOl.Models.CountryModel();
ctry2.CountryName="Africa";
ctry2.ID=2;
List<PartialViewTestSOl.Models.CountryModel> CountryList = new List<PartialViewTestSOl.Models.CountryModel>();
CountryList.Add(ctry1);
CountryList.Add(ctry2);
}
@{
Html.RenderPartial("~/Views/PartialViewTest.cshtml",CountryList );
}
Method Two Pass Through ViewBag
@{
var country = (List<PartialViewTestSOl.Models.CountryModel>)ViewBag.CountryList;
Html.RenderPartial("~/Views/PartialViewTest.cshtml",country );
}
Method Three pass through model
@{
Html.RenderPartial("~/Views/PartialViewTest.cshtml",Model.country );
}
Without the need to edit any registry keys, the Productivity Power Tools extension (available for all versions of visual studio) provides guideline functionality.
Once installed just right click while in the editor window and choose the add guide line option. Note that the guideline will always be placed on the column where your editing cursor is currently at, regardless of where you right click in the editor window.
To turn off go to options and find Productivity Power Tools
and in that section turn off Column Guides
. A reboot will be necessary.
I just got "not a working copy", and for me the reason was the Automouter on Unix. Just a fresh "cd /path/to/work/directory" did the trick.
I've had issues with using SELECT last_insert_rowid()
in a multithreaded environment. If another thread inserts into another table that has an autoinc, last_insert_rowid will return the autoinc value from the new table.
Here's where they state that in the doco:
If a separate thread performs a new INSERT on the same database connection while the sqlite3_last_insert_rowid() function is running and thus changes the last insert rowid, then the value returned by sqlite3_last_insert_rowid() is unpredictable and might not equal either the old or the new last insert rowid.
That's from sqlite.org doco
I got this message when I tried to git clone
a repo that was not mine. The fix was to fork and then clone.
Use the format()
method for objects of class "yearmon"
. Here is your example date (properly created!)
date1 <- as.yearmon("Mar 2012", "%b %Y")
Then we can extract the date parts as required:
> format(date1, "%b") ## Month, char, abbreviated
[1] "Mar"
> format(date1, "%Y") ## Year with century
[1] "2012"
> format(date1, "%m") ## numeric month
[1] "03"
These are returned as characters. Where appropriate, wrap in as.numeric()
if you want the year or numeric month as a numeric variable, e.g.
> as.numeric(format(date1, "%m"))
[1] 3
> as.numeric(format(date1, "%Y"))
[1] 2012
See ?yearmon
and ?strftime
for details - the latter explains the placeholder characters you can use.
I had this problem too and couldn't solve it without using VBA.
In my case I had a table with numbers that I wanted to be formatted and a corresponding table next to it with the desired formatting values.
i.e. While column F contains the values I want to format, the desired formatting for each cell is captured in column Z, expressed as "RED", "AMBER" or "GREEN."
Quick solution below. Manually select the range to which to apply the conditional formatting and then run the macro.
Sub ConditionalFormatting()
For Each Cell In Selection.Cells
With Cell
'clean
.FormatConditions.Delete
'green rule
.FormatConditions.Add Type:=xlExpression, Formula1:= _
"=$Z" & Cell.Row & "=""GREEN"""
.FormatConditions(.FormatConditions.Count).SetFirstPriority
With .FormatConditions(1).Font
.Color = -11489280
.TintAndShade = 0
End With
.FormatConditions(1).StopIfTrue = False
'amber rule
.FormatConditions.Add Type:=xlExpression, Formula1:= _
"=$Z" & Cell.Row & "=""AMBER"""
.FormatConditions(.FormatConditions.Count).SetFirstPriority
With .FormatConditions(1).Font
.ThemeColor = xlThemeColorAccent6
.TintAndShade = -0.249946592608417
End With
.FormatConditions(1).StopIfTrue = False
'red rule

.TintAndShade = 0
End With
.FormatConditions(1).StopIfTrue = False

If you have an access to that domain/iframe that is loaded, then you can use window.postMessage to communicate between iframe and the main window.

The Visual Studio Build tools are a different download than the IDE. They appear to be a pretty small subset, and they're called Build Tools for Visual Studio 2019 (download).
You can use the GUI to do the installation, or you can script the installation of msbuild:
vs_buildtools.exe --add Microsoft.VisualStudio.Workload.MSBuildTools --quiet
Microsoft.VisualStudio.Workload.MSBuildTools is a "wrapper" ID for the three subcomponents you need:
You can find documentation about the other available CLI switches here.
The build tools installation is much quicker than the full IDE. In my test, it took 5-10 seconds. With --quiet
there is no progress indicator other than a brief cursor change. If the installation was successful, you should be able to see the build tools in %programfiles(x86)%\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin
.
If you don't see them there, try running without --quiet
to see any error messages that may occur during installation.
You can automatically encode into Json, your complex entity with:
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer;
use Symfony\Component\Serializer\Encoder\JsonEncoder;
$serializer = new Serializer(array(new GetSetMethodNormalizer()), array('json' => new
JsonEncoder()));
$json = $serializer->serialize($entity, 'json');
If you want to use an array, you have to keep a counter which contains the number of cars in the garage. Better use an ArrayList
instead of array:
List<Car> garage = new ArrayList<Car>();
garage.add(redCar);
You can set background color of view to the UIColor with alpha, and not affect view.alpha
:
view.backgroundColor = UIColor(white: 1, alpha: 0.5)
or
view.backgroundColor = UIColor.red.withAlphaComponent(0.5)
Here are examples of output from each of the format specifiers:
N: cd26ccf675d64521884f1693c62ed303
D: cd26ccf6-75d6-4521-884f-1693c62ed303
B: {cd26ccf6-75d6-4521-884f-1693c62ed303}
P: (cd26ccf6-75d6-4521-884f-1693c62ed303)
X: {0xcd26ccf6,0x75d6,0x4521,{0x88,0x4f,0x16,0x93,0xc6,0x2e,0xd3,0x03}}
The default is D
.
Simplified update query using JOIN-ing multiple tables.
UPDATE
first_table ft
JOIN second_table st ON st.some_id = ft.some_id
JOIN third_table tt ON tt.some_id = st.some_id
.....
SET
ft.some_column = some_value
WHERE ft.some_column = 123456 AND st.some_column = 123456
Note - first_table, second_table, third_table and some_column like 123456 are demo table names, column names and ids. Replace them with the valid names.
1.THE USE OF {}:
It initialize the array with the values { }
2.The difference between String array=new String[]; and String array=new String[]{};
String array=new String[]; and String array=new String[]{}; both are invalid statement in java.
It will gives you an error that you are trying to assign String array to String datatype. More specifically error is like this Type mismatch: cannot convert from String[] to String
3.String array=new String[10]{}; got error why?
Wrong because you are defining an array of length 10 ([10]), then defining an array of length String[10]{} 0
For the official CLI client "psql" see here. And "pgAdmin3" 1.10 (still in beta) has "pgScript".
Late to the party, but I think it is a useful answer.
flatMap
would be the shortest way to do it.
Stream.of(objects).flatMap(o->(o instanceof Client)?Stream.of((Client)o):Stream.empty())
If o
is a Client
then create a Stream with a single element, otherwise use the empty stream. These streams will then be flattened into a Stream<Client>
.
you can do:
var = 1
if type(var) == int:
print('your variable is an integer')
or:
var2 = 'this is variable #2'
if type(var2) == str:
print('your variable is a string')
else:
print('your variable IS NOT a string')
hope this helps!
Dir[File.join(__dir__, "/app/**/*.rb")].each do |file|
require file
end
This will work recursively on your local machine and a remote (Like Heroku) which does not use relative paths.
The following is what I use to get the time without having to format. Some people don't like the split method, but it is useful here:
from time import ctime
print ctime().split()[3]
It will print in HH:MM:SS format.
You can look for the four underscore in this way:
create table #test
( t varchar(50) );
insert into #test values
( 'abc_1_2_3_4.gif'),
('zzz_12_3_3_45.gif');
declare @t varchar(50);
declare @t_aux varchar(50);
declare @t1 int;
declare @t2 int;
declare @t3 int;
declare @t4 int;
DECLARE t_cursor CURSOR
FOR SELECT t FROM #test
OPEN t_cursor
FETCH NEXT FROM t_cursor into @t;?
set @t1 = charindex( '_', @t )
set @t2 = charindex( '_', @t , @t1+1)
set @t3 = charindex( '_', @t , @t2+1)
set @t4 = charindex( '_', @t , @t3+1)
select @t1, @t2, t3, t4
--do a loop to iterate over all table
you can test it here.
Or in this simple way:
select
charindex( '_', t ) as first,
charindex( '_', t, charindex( '_', t ) + 1 ) as second,
...
from
#test
You have to call the function you want to be called on load (i.e., load of the document/page). For example, the function you want to load when document or page load is called "yourFunction". This can be done by calling the function on load event of the document. Please see the code below for more detail.
Try the code below:
<script src="js/jquery-1.11.0.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
yourFunction();
});
function yourFunction(){
//some code
}
</script>
Combining Giampaolo Rodolà's answer for POSIX and mine for Windows I got this:

It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null
.
Given your statement:
img1.ImageUrl = ConfigurationManager
.AppSettings
.Get("Url")
.Replace("###", randomString)
+ Server.UrlEncode(
((System.Web.UI.MobileControls.Form)Page
.FindControl("mobileForm"))
.Title);
I'm guessing either the call to AppSettings.Get("Url")
is returning null because the value isn't found or the call to Page.FindControl("mobileForm")
is returning null because the control isn't found.
You could easily break this out into multiple statements to solve the problem:
var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
as System.Web.UI.MobileControls.Form;
if(configUrl != null && mobileFormControl != null)
{
img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}
This code will verify the json independently of param object order.
var isEqualsJson = (obj1,obj2)=>{
keys1 = Object.keys(obj1);
keys2 = Object.keys(obj2);
//return true when the two json has same length and all the properties has same value key by key
return keys1.length === keys2.length && Object.keys(obj1).every(key=>obj1[key]==obj2[key]);
}
var obj1 = {a:1,b:2,c:3};
var obj2 = {a:1,b:2,c:3};
console.log("json is equals: "+ isEqualsJson(obj1,obj2));
alert("json is equals: "+ isEqualsJson(obj1,obj2));

Solved! The call build job: project, parameters: params
fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List

$(this).css('background-image', 'url(images/tabs3.png)');
});
}):
If you're debugging something and just want to see what's in there for your the print_f function formats the output nicely.
Saty described the differences between them. For your practice, you can use datetime
in order to keep the output of NOW()
.
For example:
CREATE TABLE Orders
(
OrderId int NOT NULL,
ProductName varchar(50) NOT NULL,
OrderDate datetime NOT NULL DEFAULT NOW(),
PRIMARY KEY (OrderId)
)
You can read more at w3schools.
I was looking for this same answer and I couldn't find anything that did exactly what I wanted so I created my own and posted it here:
http://seekieran.com/2011/03/jquery-scrolling-box/
Working Demo: http://jsbin.com/azoji3
Here is the important code:
function ScrollDown(){
//var topVal = $('.up').parents(".container").find(".content").css("top").replace(/[^-\d\.]/g, '');
var topVal = $(".content").css("top").replace(/[^-\d\.]/g, '');
topVal = parseInt(topVal);
console.log($(".content").height()+ " " + topVal);
if(Math.abs(topVal) < ($(".content").height() - $(".container").height() + 60)){ //This is to limit the bottom of the scrolling - add extra to compensate for issues
$('.up').parents(".container").find(".content").stop().animate({"top":topVal - 20 + 'px'},'slow');
if (mouseisdown)
setTimeout(ScrollDown, 400);
}
Recursion to make it happen:
$('.dn').mousedown(function(event) {
mouseisdown = true;
ScrollDown();
}).mouseup(function(event) {
mouseisdown = false;
});
Thanks to Jonathan Sampson for some code to start but it didn't work initially so I have heavily modified it. Any suggestions to improve it would be great here in either the comments or comments on the blog.
A lot of these answers don't bother to consider that the date is naive to begin with
To be correct, you need to make the naive date a timezone aware datetime first
import datetime
import pytz
# naive datetime
d = datetime.datetime.strptime('01/12/2011', '%d/%m/%Y')
>>> datetime.datetime(2011, 12, 1, 0, 0)
# add proper timezone
pst = pytz.timezone('America/Los_Angeles')
d = pst.localize(d)
>>> datetime.datetime(2011, 12, 1, 0, 0,
tzinfo=<DstTzInfo 'America/Los_Angeles' PST-1 day, 16:00:00 STD>)
# convert to UTC timezone
utc = pytz.UTC
d = d.astimezone(utc)
>>> datetime.datetime(2011, 12, 1, 8, 0, tzinfo=<UTC>)
# epoch is the beginning of time in the UTC timestamp world
epoch = datetime.datetime(1970,1,1,0,0,0,tzinfo=pytz.UTC)
>>> datetime.datetime(1970, 1, 1, 0, 0, tzinfo=<UTC>)
# get the total second difference
ts = (d - epoch).total_seconds()
>>> 1322726400.0
Also:
Be careful, using pytz
for tzinfo
in a datetime.datetime
DOESN'T WORK for many timezones. See datetime with pytz timezone. Different offset depending on how tzinfo is set
# Don't do this:
d = datetime.datetime(2011, 12, 1,0,0,0, tzinfo=pytz.timezone('America/Los_Angeles'))
>>> datetime.datetime(2011, 1, 12, 0, 0,
tzinfo=<DstTzInfo 'America/Los_Angeles' LMT-1 day, 16:07:00 STD>)
# tzinfo in not PST but LMT here, with a 7min offset !!!
# when converting to UTC:
d = d.astimezone(pytz.UTC)
>>> datetime.datetime(2011, 1, 12, 7, 53, tzinfo=<UTC>)
# you end up with an offset
As of Excel 2019 you could do this. The "Error" at the end is the default.
SWITCH(LEFT(A1,1), "A", "Pick Up", "B", "Collect", "C", "Prepaid", "Error")
The route()
method, which is called when you do ['route' => 'someroute']
in a form opening, wants what's called a named route. You give a route a name like this:
Route::patch('/preferences/{id}',[
'as' => 'user.preferences.update',
'uses' => 'UserController@update'
]);
That is, you make the second argument of the route into an array, where you specify both the route name (the as
), and also what to do when the route is hit (the uses
).
Then, when you open the form, you call the route:
{!! Form::model(Auth::user(), [
'method' => 'PATCH',
'route' => ['user.preferences.update', Auth::user()->id]
]) !!}
Now, for a route without parameters, you could just do 'route' => 'routename'
, but since you have a parameter, you make an array instead and supply the parameters in order.
All that said, since you appear to be updating the current user's preferences, I would advise you to let the handling controller check the id of the currently logged-in user, and base the updating on that - there's no need to send in the id in the url and the route unless your users should need to update the preferences of other users as well. :)
On modern browsers you can use the built in Intl.NumberFormat to detect the browser's number formatting and normalize the input to match.
function parseNumber(value, locales = navigator.languages) {
const example = Intl.NumberFormat(locales).format('1.1');
const cleanPattern = new RegExp(`[^-+0-9${ example.charAt( 1 ) }]`, 'g');
const cleaned = value.replace(cleanPattern, '');
const normalized = cleaned.replace(example.charAt(1), '.');
return parseFloat(normalized);
}
const corpus = {
'1.123': {
expected: 1.123,
locale: 'en-US'
},
'1,123': {
expected: 1123,
locale: 'en-US'
},
'2.123': {
expected: 2123,
locale: 'fr-FR'
},
'2,123': {
expected: 2.123,
locale: 'fr-FR'
},
}
for (const candidate in corpus) {
const {
locale,
expected
} = corpus[candidate];
const parsed = parseNumber(candidate, locale);

First, you really need to keep in mind that it's never impossible to reverse-engineer something. Everything is hackable. A smart developer using a smart IDE can already get far enough.
Well, you can find here a list. ProGuard is pretty good. I've used it myself, but only to "minify" Java code.
i have resolved same issue
"This action could not be completed. Try Again (-22421)"
using following steps...
issue
”This action could not be completed. Try Again (-22421)”
has been Resolved in Xcode 9. Now, we can upload app through Xcode Organizer also.
From https://idlebox.net/2010/apidocs/gdb-7.0.zip/gdb_9.html
The values of arguments that were not saved in their stack frames are shown as `value optimized out'.
Im guessing you compiled with -O(somevalue) and are accessing variables a,b,c in a function where optimization has occurred.
From Twitter Bootstrap documentation:
.col-sm-*
,.col-md-*
,.col-lg-*
.This is probably the shortest and easiest to reason about:
$states = array('az' => 'Arizona', 'al' => 'Alabama');
array_map(function ($short, $long) {
return array(
'short' => $short,
'long' => $long
);
}, array_keys($states), $states);
// produces:
array(
array('short' => 'az', 'long' => 'Arizona'),
array('short' => 'al', 'long' => 'Alabama')
)
The following code is what I'm using:
var altKeyDownCount = 0;
window.onkeydown = function (e) {
if (!e) e = window.event;
if (e.altKey) {
altKeyDownCount++;
if (30 < altKeyDownCount) {
$('.key').removeClass('hidden');
altKeyDownCount = 0;
}
return false;
}
}
window.onkeyup = function (e) {
if (!e) e = window.event;
altKeyDownCount = 0;
$('.key').addClass('hidden');
}
When the user keeps holding down the Alt key for some time (about 2 seconds), a group of labels (class='key hidden') appears. When the Alt key is released, the labels disappear. jQuery and Bootstrap are both used.
DBCC FREEPROCCACHE;
Use this to clear the plan cache carefully. Freeing the plan cache causes, for example, a stored procedure to be recompiled instead of reused from the cache. This can cause a sudden, temporary decrease in query performance.

The static code block can be used to instantiate or initialize class variables (as opposed to object variables). So declaring "a" static means that is only one shared by all Test objects, and the static code block initializes "a" only once, when the Test class is first loaded, no matter how many Test objects are created.

Another solution:
Based on the document, Boolean object will return true if the value is not 0, undefined, null, etc. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean
If value is omitted or is 0, -0, null, false, NaN, undefined, or the empty string (""), the object has an initial value of false.
So
if(Boolean(val)) { //executable... }
This selects all DIVs with an ID containing 'foo' and that are visible
$("div:visible[id*='foo']");
With google-drive-ftp-adapter I have been able to access the My Drive area of Google Drive with the FileZilla FTP client. However, I have not been able to access the Shared with me area.
You can configure which Google account credentials it uses by changing the account property in the configuration.properties file from default to the desired Google account name. See the instructions at http://www.andresoviedo.org/google-drive-ftp-adapter/
There are some great answers here. But recent changes to how Swift implements weak references should change everyone's weak self vs. unowned self usage decisions. Previously, if you needed the best performance using unowned self was superior to weak self, as long as you could be certain that self would never be nil, because accessing unowned self is much faster than accessing weak self.
But Mike Ash has documented how Swift has updated the implementation of weak vars to use side-tables and how this substantially improves weak self performance.
https://mikeash.com/pyblog/friday-qa-2017-09-22-swift-4-weak-references.html
Now that there isn't a significant performance penalty to weak self, I believe we should default to using it going forward. The benefit of weak self is that it's an optional, which makes it far easier to write more correct code, it's basically the reason Swift is such a great language. You may think you know which situations are safe for the use of unowned self, but my experience reviewing lots of other developers code is, most don't. I've fixed lots of crashes where unowned self was deallocated, usually in situations where a background thread completes after a controller is deallocated.
Bugs and crashes are the most time-consuming, painful and expensive parts of programming. Do your best to write correct code and avoid them. I recommend making it a rule to never force unwrap optionals and never use unowned self instead of weak self. You won't lose anything missing the times force unwrapping and unowned self actually are safe. But you'll gain a lot from eliminating hard to find and debug crashes and bugs.
If you want to have bare run
command in gdb
to execute your program with redirections and arguments, you can use set args
:
% gdb ./a.out
(gdb) set args arg1 arg2 <file
(gdb) run
I was unable to achieve the same behaviour with --args
parameter, gdb
fiercely escapes the redirections, i.e.
% gdb --args echo 1 2 "<file"
(gdb) show args
Argument list to give program being debugged when it is started is "1 2 \<file".
(gdb) run
...
1 2 <file
...
This one actually redirects the input of gdb itself, not what we really want here
% gdb --args echo 1 2 <file
zsh: no such file or directory: file
You mean something like this?
<?php
$jsonurl = "http://search.twitter.com/trends.json";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);
foreach ( $json_output->trends as $trend )
{
echo "{$trend->name}\n";
}
EDIT: This answer no longer holds true. CSS is well supportedand Javascript (read: JScript) is now pretty much required for any web experience, and few folks disable javascript.
The original answer, as my opinion in 2009.
Off the top of my head:
With CSS, you may have issues with browser support.
With JScript, people can disable jscript (thats what I do).
I believe the preferred method is to do content in HTML, Layout with CSS, and anything dynamic in JScript. So in this instance, you would probably want to take the CSS approach.
Here is a compact, object oriented, recursive implementation:
class BTreeNode(object):
def __init__(self, data):
self.data = data
self.rChild = None
self.lChild = None
def __str__(self):
return (self.lChild.__str__() + '<-' if self.lChild != None else '') + self.data.__str__() + ('->' + self.rChild.__str__() if self.rChild != None else '')
def insert(self, btreeNode):
if self.data > btreeNode.data: #insert left
if self.lChild == None:
self.lChild = btreeNode
else:
self.lChild.insert(btreeNode)
else: #insert right
if self.rChild == None:
self.rChild = btreeNode
else:
self.rChild.insert(btreeNode)
def main():
btreeRoot = BTreeNode(5)
print 'inserted %s:' %5, btreeRoot
btreeRoot.insert(BTreeNode(7))
print 'inserted %s:' %7, btreeRoot
btreeRoot.insert(BTreeNode(3))
print 'inserted %s:' %3, btreeRoot
btreeRoot.insert(BTreeNode(1))
print 'inserted %s:' %1, btreeRoot
btreeRoot.insert(BTreeNode(2))
print 'inserted %s:' %2, btreeRoot
btreeRoot.insert(BTreeNode(4))
print 'inserted %s:' %4, btreeRoot
btreeRoot.insert(BTreeNode(6))
print 'inserted %s:' %6, btreeRoot
The output of the above main() is:
inserted 5: 5
inserted 7: 5->7
inserted 3: 3<-5->7
inserted 1: 1<-3<-5->7
inserted 2: 1->2<-3<-5->7
inserted 4: 1->2<-3->4<-5->7
inserted 6: 1->2<-3->4<-5->6<-7
The optimal solution is probably one that does not include an additional database read operation prior to saving the model instance, nor any further django-library. This is why laffuste's solutions is preferable. In the context of an admin site, one can simply override the save_model
-method, and invoke the form's has_changed
method there, just as in Sion's answer above. You arrive at something like this, drawing on Sion's example setting but using changed_data
to get every possible change:
class ModelAdmin(admin.ModelAdmin):
fields=['name','mode']
def save_model(self, request, obj, form, change):
form.changed_data #output could be ['name']
#do somethin the changed name value...
#call the super method
super(self,ModelAdmin).save_model(request, obj, form, change)
save_model
:https://docs.djangoproject.com/en/1.10/ref/contrib/admin/#django.contrib.admin.ModelAdmin.save_model
changed_data
-method for a Field:https://docs.djangoproject.com/en/1.10/ref/forms/api/#django.forms.Form.changed_data
You are copying all files to a single file called TEST_BACKUP_FOLDER
try this:
md TEST_BACKUP_FOLDER
copy "\\My_Servers_IP\Shared Drive\FolderName\*" TEST_BACKUP_FOLDER
As discussed here, there really isn't such a thing as an HTTP connection and what httplib refers to as the HTTPConnection is really the underlying TCP connection which doesn't really know much about your requests at all. Requests abstracts that away and you won't ever see it.
The newest version of Requests does in fact keep the TCP connection alive after your request.. If you do want your TCP connections to close, you can just configure the requests to not use keep-alive.
s = requests.session()
s.config['keep_alive'] = False
Sometimes you still need to use FirstOrDefault if you have to do different tests. If the Key component of your dictionnary is nullable, you can do this:
thisTag = _tags.FirstOrDefault(t => t.Key.SubString(1,1) == 'a');
if(thisTag.Key != null) { ... }
Using FirstOrDefault, the returned KeyValuePair's key and value will both be null if no match is found.
for Title Bar
requestWindowFeature(Window.FEATURE_NO_TITLE);
for fullscreen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Place this after
super.onCreate(savedInstanceState);
but before
setContentView(R.layout.xml);
This worked for me.try this
In my case onChange event was typed as React.ChangeEvent:
onChange={ (e: React.ChangeEvent<HTMLSelectElement>) => {
console.warn('onChange TextInput value: ' + e.target.value);
}
}
You can just go for String
replace method.-
line1 = line1.replace("\"", "");
For Selenium Remote Control with Java:
selenium.keyPress("elementID", "\13");
For Selenium WebDriver (a.k.a. Selenium 2) with Java:
driver.findElement(By.id("elementID")).sendKeys(Keys.ENTER);
Or,
driver.findElement(By.id("elementID")).sendKeys(Keys.RETURN);
Another way to press Enter in WebDriver is by using the Actions class:
Actions action = new Actions(driver);
action.sendKeys(driver.findElement(By.id("elementID")), Keys.ENTER).build().perform();
You can use something called Dash: Offline API Documentation
for Mac. For Windows and Linux you have an alternative called Zeal
.
Both of them are very similar. And you can get offline documentation for most of the APIs out there like Java, android, Angular, HTML5 etc .. almost everything.
I have also written a post on How to install Zeal on Ubuntu 14.04
You can also do this
<input type="hidden" name="text" value="{% url 'dashboard' %}" />
Solution without creating Service, using $rootScope:
To share properties across app Controllers you can use Angular $rootScope. This is another option to share data, putting it so that people know about it.
The preferred way to share some functionality across Controllers is Services, to read or change a global property you can use $rootscope.
var app = angular.module('mymodule',[]);
app.controller('Ctrl1', ['$scope','$rootScope',
function($scope, $rootScope) {
$rootScope.showBanner = true;
}]);
app.controller('Ctrl2', ['$scope','$rootScope',
function($scope, $rootScope) {
$rootScope.showBanner = false;
}]);
Using $rootScope in a template (Access properties with $root):
<div ng-controller="Ctrl1">
<div class="banner" ng-show="$root.showBanner"> </div>
</div>
Assuming your df.index is sorted you can use:
df.loc[df.index.max() + 1] = None
It handles well different indexes and column types.
[EDIT] it works with pd.DatetimeIndex if there is a constant frequency, otherwise we must specify the new index exactly e.g:
df.loc[df.index.max() + pd.Timedelta(milliseconds=1)] = None
long example:
df = pd.DataFrame([[pd.Timestamp(12432423), 23, 'text_field']],
columns=["timestamp", "speed", "text"],
index=pd.DatetimeIndex(start='2111-11-11',freq='ms', periods=1))
df.info()
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 1 entries, 2111-11-11 to 2111-11-11
Freq: L
Data columns (total 3 columns):
timestamp 1 non-null datetime64[ns]
speed 1 non-null int64
text 1 non-null object
dtypes: datetime64[ns](1), int64(1), object(1)
memory usage: 32.0+ bytes
df.loc[df.index.max() + 1] = None
df.info()
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2 entries, 2111-11-11 00:00:00 to 2111-11-11 00:00:00.001000
Data columns (total 3 columns):
timestamp 1 non-null datetime64[ns]
speed 1 non-null float64
text 1 non-null object
dtypes: datetime64[ns](1), float64(1), object(1)
memory usage: 64.0+ bytes
df.head()

This did the trick for me. It captures all the stdout output from the subprocess(For python 3.8):
from subprocess import check_output, STDOUT
cmd = "Your Command goes here"
try:
cmd_stdout = check_output(cmd, stderr=STDOUT, shell=True).decode()
except Exception as e:
print(e.output.decode()) # print out the stdout messages up to the exception
print(e) # To print out the exception message
Table structure...very basic:
create table tabla(ID int, Stuff varchar (50));
insert into tabla values(1, '32.43');
insert into tabla values(2, '43.33');
insert into tabla values(3, '23.22');
Query:
SELECT SUM(cast(Stuff as decimal(4,2))) as result FROM tabla
Or, try this:
SELECT SUM(cast(isnull(Stuff,0) as decimal(12,2))) as result FROM tabla
Working on SQLServer 2008
Having <thead>
and <tbody>
with the same numbers of <th>
and <td>
solved my problem.
Since you are copying tha same data to all rows, you don't actually need to loop at all. Try this:
Sub ARRAYER()
Dim Number_of_Sims As Long
Dim rng As Range
Application.Calculation = xlCalculationManual
Application.ScreenUpdating = False
Number_of_Sims = 100000
Set rng = Range("C4:G4")
rng.Offset(1, 0).Resize(Number_of_Sims) = rng.Value
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
End Sub
This thread is a bit older but here something I just came across:
Try this code:
$date = new DateTime();
$arr = ['date' => $date];
echo $date->format('Ymd') . '<br>';
mytest($arr);
echo $date->format('Ymd') . '<br>';
function mytest($params = []) {
if (isset($params['date'])) {
$params['date']->add(new DateInterval('P1D'));
}
}
http://codepad.viper-7.com/gwPYMw
Note there is no amp for the $params parameter and still it changes the value of $arr['date']. This doesn't really match with all the other explanations here and what I thought until now.
If I clone the $params['date'] object, the 2nd outputted date stays the same. If I just set it to a string it doesn't effect the output either.
In MySQL, certain words like SELECT
, INSERT
, DELETE
etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.
As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):
Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.
...
If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.
...
The identifier quote character is the backtick ("
`
"):
A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.
You have two options.
The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.
Doing this has a couple of advantages:
It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.
The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.
Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.
If renaming the table or column isn't possible, wrap the offending identifier in backticks (`
) as described in the earlier quote from 10.2 Schema Object Names.
An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):
mysql> CREATE TABLE interval (begin INT, end INT); ERROR 1064 (42000): You have an error in your SQL syntax. near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT); Query OK, 0 rows affected (0.01 sec)
Similarly, the query from the question can be fixed by wrapping the keyword key
in backticks, as shown below:
INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)"; ^ ^
BalusC gave a good description about the problem but it lacks a good end to end code that users can pick and test it for themselves.
Best practice is to always store date-time in UTC timezone in DB. Sql timestamp type does not have timezone info.
When writing datetime value to sql db
//Convert the time into UTC and build Timestamp object.
Timestamp ts = Timestamp.valueOf(LocalDateTime.now(ZoneId.of("UTC")));
//use setTimestamp on preparedstatement
preparedStatement.setTimestamp(1, ts);
When reading the value back from DB into java,
Then, change it to your desired timezone. Here I am changing it to Toronto timezone.
ResultSet resultSet = preparedStatement.executeQuery();
resultSet.next();
Timestamp timestamp = resultSet.getTimestamp(1);
ZonedDateTime timeInUTC = timestamp.toLocalDateTime().atZone(ZoneId.of("UTC"));
LocalDateTime timeInToronto = LocalDateTime.ofInstant(timeInUTC.toInstant(), ZoneId.of("America/Toronto"));
You can SSH in to docker container as root by using
docker exec -it --user root <container_id> /bin/bash
Then change root password using this
passwd root
Make sure sudo is installed check by entering
sudo
if it is not installed install it
apt-get install sudo
If you want to give sudo permissions for user dev you can add user dev to sudo group
usermod -aG sudo dev
Now you'll be able to run sudo level commands from your dev user while inside the container or else you can switch to root inside the container by using the password you set earlier.
To test it login as user dev and list the contents of root directory which is normally only accessible to the root user.
sudo ls -la /root
Enter password for dev
If your user is in the proper group and you entered the password correctly, the command that you issued with sudo should run with root privileges.

You can stringify the JSON Object with JSON.stringify(jsonObject) and receive it on controller as String.
In the Controller, you can use the javax.json to convert and manipulate this.
Download and add the .jar to the project libs and import the JsonObject.
To create an json object, you can use
JsonObjectBuilder job = Json.createObjectBuilder();
job.add("header1", foo1);
job.add("header2", foo2);
JsonObject json = job.build();
To read it from String, you can use
JsonReader jr = Json.createReader(new StringReader(jsonString));
JsonObject json = jsonReader.readObject();
jsonReader.close();
Another option would be to add engine='python'
to the command pandas.read_csv(filename, sep='\t', engine='python')
gettimeofday will return time accurate to microseconds within the resolution of the system clock. You might also want to check out the High Res Timers project on SourceForge.
Sorry this is too late but maybe useful

I, like @D.E. White, came here for similar but different reasons than the original question. The original question asks for the last 365 days. @samjudson's answer provides that. @D.E. White's answer returns results for the prior calendar year.
My query is a bit different in that it works for the prior year up to and including the current date:
SELECT .... FROM .... WHERE year(date) > year(DATEADD(year, -2, GETDATE()))
For example, on Feb 17, 2017 this query returns results from 1/1/2016 to 2/17/2017
Another solution is the one described here at the end of this post by "enlian": http://springinpractice.com/2013/10/07/handling-json-error-object-responses-with-springs-resttemplate
try{
restTemplate.exchange(...)
} catch(HttpStatusCodeException e){
String errorpayload = e.getResponseBodyAsString();
//do whatever you want
} catch(RestClientException e){
//no response payload, tell the user sth else
}
I have opened a (trivial) bug for this at m2e. Vote for it if you want the warning message to be gone for good...
as noted here, this is what worked best for me:
sudo apt-get install python3 python3-pip python3-setuptools
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
Using ES6 the javascript becomes a little cleaner
handleFiles(input) {
const file = input.target.files[0];
const reader = new FileReader();
reader.onload = (event) => {
const file = event.target.result;
const allLines = file.split(/\r\n|\n/);
// Reading line by line
allLines.forEach((line) => {
console.log(line);
});
};
reader.onerror = (event) => {
alert(event.target.error.name);
};
reader.readAsText(file);
}
Perform three steps:
Go to "WorkBench Preferences" --> Choose "SQL Editor" Under "Query Results": check "Treat BINARY/VARBINARY as nonbinary character string"
Restart MySQL WorkBench.
Now select SELECT SUBSTRING(BLOB<COLUMN_NAME>,1,2500) FROM <Table_name>;
You can with regular expressions Input Patterns (check browser compatibility)
<input id="password" name="password" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Must have at least 6 characters' : ''); if(this.checkValidity()) form.password_two.pattern = this.value;" placeholder="Password" required>
<input id="password_two" name="password_two" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Please enter the same Password as above' : '');" placeholder="Verify Password" required>
Below is an other approach that was useful for me

To elaborate on @Bakuriu's answer above, I've found that this enables me to catch a runtime warning in a similar fashion to how I would catch an error warning, printing out the warning nicely:
import warnings
with warnings.catch_warnings():
warnings.filterwarnings('error')
try:
answer = 1 / 0
except Warning as e:
print('error found:', e)
You will probably be able to play around with placing of the warnings.catch_warnings() placement depending on how big of an umbrella you want to cast with catching errors this way.
JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.
var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
//red
textBox.style.backgroundColor = "#FF0000";
}
else
{
//green
textBox.style.backgroundColor = "#00FF00";
}
const setTimeoutAsync = (cb, delay) =>
new Promise((resolve) => {
setTimeout(() => {
resolve(cb());
}, delay);
});
We can pass custom 'cb fxn' like this one
I know this is an old post BUT I have been having problems getting WAMP server seen on my windows 7 pro network for days, tried all of the solutions offered (including changing windows system files) but still not working. finally in pure desperation I put everything on the system back as it was and installed WAMP Server on a different drive (E:\WAMP ) in my case. The result was it worked perfectly first time with no editing configs or messing with the system. Other users may wish to try this before reaching the 'tear your hair out stage', it certainly saved my sanity or what I have left of it I hope this helps someone Dave
You need a back inserter to copy into vectors:
std::copy(str.c_str(), str.c_str()+str.length(), back_inserter(data));
Not an answer to the original question, but an example to the how-to-make-reusable and working custom renderers without breaking MVC :-)
// WRONG
public class DataWrapper {
final Data data;
final String description;
public DataWrapper(Object data, String description) {
this.data = data;
this.description = description;
}
....
@Override
public String toString() {
return description;
}
}
// usage
myModel.add(new DataWrapper(data1, data1.getName());
It is wrong in a MVC environment, because it is mixing data and view: now the model doesn't contain the data but a wrapper which is introduced for view reasons. That's breaking separation of concerns and encapsulation (every class interacting with the model needs to be aware of the wrapped data).
The driving forces for breaking of rules were:
As in Swing a custom renderer is the small coin designed to accomodate for custom visual representation, a default manager which can't cope is ... broken. Tweaking design just to accommodate for such a crappy default is the wrong way round, kind of upside-down. The correct is, to implement a coping manager.
While re-use is fine, doing so at the price of breaking the basic architecture is not a good bargin.
We have a problem in the presentation realm, let's solve it in the presentation realm with the elements designed to solve exactly that problem. As you might have guessed, SwingX already has such a solution :-)
In SwingX, the provider of a string representation is called StringValue, and all default renderers take such a StringValue to configure themselves:
StringValue sv = new StringValue() {
@Override
public String getString(Object value) {
if (value instanceof Data) {
return ((Data) value).getSomeProperty();
}
return TO_STRING.getString(value);
}
};
DefaultListRenderer renderer = new DefaultListRenderer(sv);
As the defaultRenderer is-a StringValue (implemented to delegate to the given), a well-behaved implementation of KeySelectionManager now can delegate to the renderer to find the appropriate item:
public BetterKeySelectionManager implements KeySelectionManager {
@Override
public int selectionForKey(char ch, ComboBoxModel model) {
....
if (getCellRenderer() instance of StringValue) {
String text = ((StringValue) getCellRenderer()).getString(model.getElementAt(row));
....
}
}
}
Outlined the approach because it is easily implementable even without using SwingX, simply define implement something similar and use it:
All except the string provider is reusable as-is (that is exactly one implemenation of the custom renderer and the keySelectionManager). There can be general implementations of the string provider, f.i. those formatting value or using bean properties via reflection. And all without breaking basic rules :-)
How to change multiple "dogsss" to "dollsss":
$('#id1 p').each(function() {
var text = $(this).text();
// Use global flag i.e. g in the regex to replace all occurrences
$(this).text(text.replace(/dog/g, 'doll'));
});

I'm not a fan of dynamic SQL but it does have its uses for exploratory queries like this.
None of the answers here solved my issue (as at February 2020), so I raised an issue at https://issues.apache.org/jira/browse/NETBEANS-3903 and Netbeans fixed the issue!
They're working on a pull request so the fix will be in a future .dmg installer soon, but in the meantime you can copy a file referenced in the bug and replace one in your netbeans modules folder.
Tip - if you right click on Applications > Netbeans and choose Show Package Contents then you can find and replace the file org-netbeans-modules-tomcat5.jar that they refer to in your Netbeans folder, e.g. within /Applications/NetBeans/Apache NetBeans 11.2.app/Contents/Resources/NetBeans/netbeans/enterprise/modules
You can also use DBMS_METADATA:
select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY', 'PADCAMPAIGN')

Programmatically in Swift 5 with Xcode 10.2
Building on top of @La masse's solution, but using autolayout to support rotation
Set anchors for the view's position (left, top, centerY, centerX, etc). You can also set the width anchor or set the frame.width dynamically with the UIScreen extension provided (to support rotation)
label = UILabel()
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
self.view.addSubview(label)
// SET AUTOLAYOUT ANCHORS
label.translatesAutoresizingMaskIntoConstraints = false
label.leftAnchor.constraint(equalTo: self.view.leftAnchor, constant: 20).isActive = true
label.rightAnchor.constraint(equalTo: self.view.rightAnchor, constant: -20).isActive = true
label.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 20).isActive = true
// OPTIONALLY, YOU CAN USE THIS INSTEAD OF THE WIDTH ANCHOR (OR LEFT/RIGHT)
// label.frame.size = CGSize(width: UIScreen.absoluteWidth() - 40.0, height: 0)
label.text = "YOUR LONG TEXT GOES HERE"
label.sizeToFit()
If setting frame.width dynamically using UIScreen:
extension UIScreen { // OPTIONAL IF USING A DYNAMIC FRAME WIDTH
class func absoluteWidth() -> CGFloat {
var width: CGFloat
if UIScreen.main.bounds.width > UIScreen.main.bounds.height {
width = self.main.bounds.height // Landscape
} else {
width = self.main.bounds.width // Portrait
}
return width
}
}
First create UIImageView then add image in UIImageView .
var imageView : UIImageView
imageView = UIImageView(frame:CGRectMake(10, 50, 100, 300));
imageView.image = UIImage(named:"image.jpg")
self.view.addSubview(imageView)
As detailed out in the bookdown documentation, you could also use a paged table
mtcars %>% tbl_df %>% rmarkdown::paged_table()
This will paginate the data and allows to browse all rows and columns (unless configured to cap the rows). Example:
Try this:
INSERT INTO test_table (SELECT null,txt FROM test_table)
Every time you run this query, This will insert all the rows again with new ids. values in your table and will increase exponentially.
I used a table with two columns i.e id and txt and id is auto increment.
I think this should work .. :)
<input type="checkbox" name="Days[]" value="Daily">Daily<br>

I used to add files beyond symlinks for quite some time now. This used to work just fine, without making any special arrangements. Since I updated to Git 1.6.1, this does not work any more.
You may be able to switch to Git 1.6.0 to make this work. I hope that a future version of Git will have a flag to git-add
allowing it to follow symlinks again.
I won't be explaining how the floats work here (in detail), as this question generally focuses on Why use clear: both;
OR what does clear: both;
exactly do...
I'll keep this answer simple, and to the point, and will explain to you graphically why clear: both;
is required or what it does...
Generally designers float the elements, left or to the right, which creates an empty space on the other side which allows other elements to take up the remaining space.
Elements are floated when the designer needs 2 block level elements side by side. For example say we want to design a basic website which has a layout like below...

Note: You might have to add header
, footer
, aside
, section
(and other HTML5 elements) as display: block;
in your stylesheet for explicitly mentioning that the elements are block level elements.
I have a basic layout, 1 header, 1 side bar, 1 content area and 1 footer.
No floats for header
, next comes the aside
tag which I'll be using for my website sidebar, so I'll be floating the element to left.
Note: By default, block level element takes up document 100% width, but when floated left or right, it will resize according to the content it holds.
So as you note, the left floated div
leaves the space to its right unused, which will allow the div
after it to shift in the remaining space.
div
's will render one after the other if they are NOT floateddiv
will shift beside each other if floated left or rightOk, so this is how block level elements behave when floated left or right, so now why is clear: both;
required and why?
So if you note in the layout demo - in case you forgot, here it is..
I am using a class called .clear
and it holds a property called clear
with a value of both
. So lets see why it needs both
.
I've floated aside
and section
elements to the left, so assume a scenario, where we have a pool, where header
is solid land, aside
and section
are floating in the pool and footer is solid land again, something like this..
So the blue water has no idea what the area of the floated elements are, they can be bigger than the pool or smaller, so here comes a common issue which troubles 90% of CSS beginners: why the background of a container element is not stretched when it holds floated elements. It's because the container element is a POOL here and the POOL has no idea how many objects are floating, or what the length or breadth of the floated elements are, so it simply won't stretch.
(Refer [Clearfix] section of this answer for neat way to do this. I am using an empty div
example intentionally for explanation purpose)
I've provided 3 examples above, 1st is the normal document flow where red
background will just render as expected since the container doesn't hold any floated objects.
In the second example, when the object is floated to left, the container element (POOL) won't know the dimensions of the floated elements and hence it won't stretch to the floated elements height.
After using clear: both;
, the container element will be stretched to its floated element dimensions.
Another reason the clear: both;
is used is to prevent the element to shift up in the remaining space.
Say you want 2 elements side by side and another element below them... So you will float 2 elements to left and you want the other below them.
div
Floated left resulting in section
moving into remaining spacediv
cleared so that the section
tag will render below the floated div
s Last but not the least, the footer
tag will be rendered after floated elements as I've used the clear
class before declaring my footer
tags, which ensures that all the floated elements (left/right) are cleared up to that point.
Coming to clearfix which is related to floats. As already specified by @Elky, the way we are clearing these floats is not a clean way to do it as we are using an empty div
element which is not a div
element is meant for. Hence here comes the clearfix.
Think of it as a virtual element which will create an empty element for you before your parent element ends. This will self clear your wrapper element holding floated elements. This element won't exist in your DOM literally but will do the job.
To self clear any wrapper element having floated elements, we can use
.wrapper_having_floated_elements:after { /* Imaginary class name */
content: "";
clear: both;
display: table;
}
Note the :after
pseudo element used by me for that class
. That will create a virtual element for the wrapper element just before it closes itself. If we look in the dom you can see how it shows up in the Document tree.
So if you see, it is rendered after the floated child div
where we clear the floats which is nothing but equivalent to have an empty div
element with clear: both;
property which we are using for this too. Now why display: table;
and content
is out of this answers scope but you can learn more about pseudo element here.
Note that this will also work in IE8 as IE8 supports :after
pseudo.
Most of the developers float their content left or right on their pages, probably divs holding logo, sidebar, content etc., these divs are floated left or right, leaving the rest of the space unused and hence if you place other containers, it will float too in the remaining space, so in order to prevent that clear: both;
is used, it clears all the elements floated left or right.
------------------ ----------------------------------
div1(Floated Left) Other div takes up the space here
------------------ ----------------------------------
Now what if you want to make the other div render below div1
, so you'll use clear: both;
so it will ensure you clear all floats, left or right
------------------
div1(Floated Left)
------------------
<div style="clear: both;"><!--This <div> acts as a separator--></div>
----------------------------------
Other div renders here now
----------------------------------
If you have to make a lot of "id" lookups and it should be really fast you should use a second array containing all the "ids" as keys:
$lookup_array=array();
foreach($my_array as $arr){
$lookup_array[$arr['id']]=1;
}
Now you can check for an existing id very fast, for example:
echo (isset($lookup_array[152]))?'yes':'no';
firstOrCreate() checks for all the arguments to be present before it finds a match.
If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) like
$user = User::firstOrCreate([
'email' => '[email protected]'
], [
'firstName' => 'abcd',
'lastName' => 'efgh',
'veristyName'=>'xyz',
]);
Then it check only the email
This:
lst = [8 for i in range(9)]
creates a list, elements are initialized 8
but this:
lst = [0] * 7
would create 7 lists which have one element
You can always use the definition of xor to compute it from other logical operations:
(a and not b) or (not a and b)
But this is a little too verbose for me, and isn't particularly clear at first glance. Another way to do it is:
bool(a) ^ bool(b)
The xor operator on two booleans is logical xor (unlike on ints, where it's bitwise). Which makes sense, since bool
is just a subclass of int
, but is implemented to only have the values 0
and 1
. And logical xor is equivalent to bitwise xor when the domain is restricted to 0
and 1
.
So the logical_xor
function would be implemented like:
def logical_xor(str1, str2):
return bool(str1) ^ bool(str2)

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Good luck with your implementation.
The Babel docs describe this pretty concisely:
Babel includes a polyfill that includes a custom regenerator runtime and core.js.
This will emulate a full ES6 environment. This polyfill is automatically loaded when using babel-node and babel/register.
Make sure you require it at the entry-point to your application, before anything else is called. If you're using a tool like webpack, that becomes pretty simple (you can tell webpack to include it in the bundle).
If you're using a tool like gulp-babel
or babel-loader
, you need to also install the babel
package itself to use the polyfill.
Also note that for modules that affect the global scope (polyfills and the like), you can use a terse import to avoid having unused variables in your module:
import 'babel/polyfill';
Epydoc is a tool to generate API documentation from Python source code. It also generates UML class diagrams, using Graphviz in fancy ways. Here is an example of diagram generated from the source code of Epydoc itself.
Because Epydoc performs both object introspection and source parsing it can gather more informations respect to static code analysers such as Doxygen: it can inspect a fair amount of dynamically generated classes and functions, but can also use comments or unassigned strings as a documentation source, e.g. for variables and class public attributes.
The shortest one I could come up with is:
chmod -R a=r,u+w,a+X /foo
which works on GNU/Linux, and I believe on Posix in general (from my reading of: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/chmod.html).
What this does is:
Importantly, the step 1 permission clears all execute bits, so step 3 only adds back execute bits for directories (never files). In addition, all three steps happen before a directory is recursed into (so this is not equivalent to e.g.
chmod -R a=r /foo
chmod -R u+w /foo
chmod -R a+X /foo
since the a=r removes x from directories, so then chmod can't recurse into them.)
You can use lookups in Ansible in order to get the contents of a file, e.g.
user_data: "{{ lookup('file', user_data_file) }}"
Caveat: This lookup will work with local files, not remote files.
Here's a complete example from the docs:
- hosts: all
vars:
contents: "{{ lookup('file', '/etc/foo.txt') }}"
tasks:
- debug: msg="the value of foo.txt is {{ contents }}"
&& and || are short circuit operators operating on scalars. & and | operate on arrays, and use short-circuiting only in the context of if
or while
loop expressions.
You Can use https://github.com/Flipboard/FLAnimatedImage
#import "FLAnimatedImage.h"
NSData *dt=[NSData dataWithContentsOfFile:path];
imageView1 = [[FLAnimatedImageView alloc] init];
FLAnimatedImage *image1 = [FLAnimatedImage animatedImageWithGIFData:dt];
imageView1.animatedImage = image1;
imageView1.frame = CGRectMake(0, 5, 168, 80);
[self.view addSubview:imageView1];
Ok, I know there is an accepted answer but… for more special cases you also could use this one:
array_map(function($n) { echo $n['filename']; echo $n['filepath'];},$array);
Or in a more un-complex way:
function printItem($n){
echo $n['filename'];
echo $n['filepath'];
}
array_map('printItem', $array);
This will allow you to manipulate the data in an easier way.
SET path of JRE as well
jre is nothing but responsible for execute the program
PATH Variable value:
C:\Program Files\Java\jdk1.8.0\bin;C:\Program Files\Java\jre\bin;.;
The return
there is returning from the lambda expression rather than from the containing method. Instead of forEach
you need to filter
the stream:
players.stream().filter(player -> player.getName().contains(name))
.findFirst().orElse(null);
Here filter
restricts the stream to those items that match the predicate, and findFirst
then returns an Optional
with the first matching entry.
This looks less efficient than the for-loop approach, but in fact findFirst()
can short-circuit - it doesn't generate the entire filtered stream and then extract one element from it, rather it filters only as many elements as it needs to in order to find the first matching one. You could also use findAny()
instead of findFirst()
if you don't necessarily care about getting the first matching player from the (ordered) stream but simply any matching item. This allows for better efficiency when there's parallelism involved.
If the list contains unhashable items, you can use Alex Martelli's solution but with a list instead of a set, though it's slower for larger inputs: O(N^2).
def has_duplicates(iterable):
seen = []
for x in iterable:
if x in seen:
return True
seen.append(x)

Had the same error. My problem was caused from shifting around my project directory, and failing to adjust the path to my static files on the server to reflect the new path (i.e. was ./src/public

You should only need to do a single join:
SELECT e.Grade, v.Score, e.CaseNum, e.FileNum, e.ActivityNum
FROM Evaluation e
INNER JOIN Value v ON e.CaseNum = v.CaseNum AND e.FileNum = v.FileNum AND e.ActivityNum = v.ActivityNum
$('#saveBtn').off('click').on('click',function(){
saveQuestion(id)
});
Since the problem is the non-trivial destructor so if the destructor is removed from the std::string
, it's possible to define a constexpr
instance of that type. Like this
struct constexpr_str {
char const* str;
std::size_t size;
// can only construct from a char[] literal
template <std::size_t N>
constexpr constexpr_str(char const (&s)[N])
: str(s)
, size(N - 1) // not count the trailing nul
{}
};
int main()
{
constexpr constexpr_str s("constString");
// its .size is a constexpr
std::array<int, s.size> a;
return 0;
}
Use something like this:
page1.php
<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>
Any other PHP page:
<?php
session_start();
echo $_SESSION['myValue'];
?>
A few notes to keep in mind though: You need to call session_start()
BEFORE any output, HTML, echos - even whitespace.
You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.
The setting of the variable itself can be done in one of a number of ways:
$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];
And if you want to check if the variable is set before getting a potential error, use something like this:
if(!empty($_SESSION['myValue'])
{
echo $_SESSION['myValue'];
}
else
{
echo "Session not set yet.";
}
Use the class URLEncoder:
URLEncoder.encode(String s, String enc)
Where :
s - String to be translated.
enc - The name of a supported character encoding.
Standard charsets:
US-ASCII Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set ISO-8859-1 ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1
UTF-8 Eight-bit UCS Transformation Format
UTF-16BE Sixteen-bit UCS Transformation Format, big-endian byte order
UTF-16LE Sixteen-bit UCS Transformation Format, little-endian byte order
UTF-16 Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark
Example:
import java.net.URLEncoder;
String stringEncoded = URLEncoder.encode(
"This text must be encoded! aeiou áéíóú ñ, peace!", "UTF-8");
Mongo sends the complete document as a callbackobject so you can simply get it from there only.
for example
collection.save(function(err,room){
var newRoomId = room._id;
});
You may also delete gradle file, if you don't use gradle any where else:

I use the following code to write files on my web directory.
write_file.html
<form action="file.php"method="post">
<textarea name="code">Code goes here</textarea>
<input type="submit"value="submit">
</form>
write_file.php
<?php
// strip slashes before putting the form data into target file
$cd = stripslashes($_POST['code']);
// Show the msg, if the code string is empty
if (empty($cd))
echo "Nothing to write";
// if the code string is not empty then open the target file and put form data in it
else
{
$file = fopen("demo.php", "w");
echo fwrite($file, $cd);
// show a success msg
echo "data successfully entered";
fclose($file);
}
?>
This is a working script. be sure to change the url in form action and the target file in fopen() function if you want to use it on your site.
Good luck.
Wikipedia's answer for "lexicographic order" seems perfectly explicit in cookbook style to me. It cites a 14th century origin for the algorithm!
I've just written a quick implementation in Java of Wikipedia's algorithm as a check and it was no trouble. But what you have in your Q as an example is NOT "list all permutations", but "a LIST of all permutations", so wikipedia won't be a lot of help to you. You need a language in which lists of permutations are feasibly constructed. And believe me, lists a few billion long are not usually handled in imperative languages. You really want a non-strict functional programming language, in which lists are a first-class object, to get out stuff while not bringing the machine close to heat death of the Universe.
That's easy. In standard Haskell or any modern FP language:
-- perms of a list
perms :: [a] -> [ [a] ]
perms (a:as) = [bs ++ a:cs | perm <- perms as, (bs,cs) <- splits perm]
perms [] = [ [] ]
and
-- ways of splitting a list into two parts
splits :: [a] -> [ ([a],[a]) ]
splits [] = [ ([],[]) ]
splits (a:as) = ([],a:as) : [(a:bs,cs) | (bs,cs) <- splits as]
For .net core 2.1 console application, the following approaches worked for me:
1 - from CLI (after building the application and navigating to debug or release folders based on the build type specified):
dotnet appName.dll
2 - from Visual Studio
R.C solution and click publish
'Target location' -> 'configure' ->
'Deployment Mode' = 'Self-Contained'
'Target Runtime' = 'win-x64 or win-x86 depending on the OS'

As an alternative to using git config --global http.proxy address:port
, you can set the proxy on the command line:
git -c "http.proxy=address:port" clone https://...
The advantage is the proxy is not persistently set. Under Bash you might set an alias:
alias git-proxy='git -c "http.proxy=address:port"'
I removed the float from the second div to make it work.
Maybe it would be better if you would read your excel file from PHP, and then either save it to a DB or do some processing on it.

Sorry for posting to such an old thread -- but as someone who also shares a passion for pythonic 'best', I thought I'd share our solution.
The solution is to build SQL statements using python's String Literal Concatenation (http://docs.python.org/), which could be qualified a somewhere between Option 2 and Option 4
Code Sample:
sql = ("SELECT field1, field2, field3, field4 "
"FROM table "
"WHERE condition1=1 "
"AND condition2=2;")
Works as well with f-strings:
fields = "field1, field2, field3, field4"
table = "table"
conditions = "condition1=1 AND condition2=2"
sql = (f"SELECT {fields} "
f"FROM {table} "
f"WHERE {conditions};")
A boolean
cannot be null
in java.
A Boolean
, however, can be null
.
If a boolean
is not assigned a value (say a member of a class) then it will be false
by default.
With PowerShell you can solve the problem neatly by piping Invoke-Sqlcmd into Export-Csv.
#Requires -Module SqlServer
Invoke-Sqlcmd -Query "SELECT * FROM DimDate;" `
-Database AdventureWorksDW2012 `
-Server localhost |
Export-Csv -NoTypeInformation `
-Path "DimDate.csv" `
-Encoding UTF8
SQL Server 2016 includes the SqlServer module, which contains the Invoke-Sqlcmd
cmdlet, which you'll have even if you just install SSMS 2016. Prior to that, SQL Server 2012 included the old SQLPS module, which would change the current directory to SQLSERVER:\
when the module was first used (among other bugs) so for it, you'll need to change the #Requires
line above to:
Push-Location $PWD
Import-Module -Name SQLPS
# dummy query to catch initial surprise directory change
Invoke-Sqlcmd -Query "SELECT 1" `
-Database AdventureWorksDW2012 `
-Server localhost |Out-Null
Pop-Location
# actual Invoke-Sqlcmd |Export-Csv pipeline
To adapt the example for SQL Server 2008 and 2008 R2, remove the #Requires
line entirely and use the sqlps.exe utility instead of the standard PowerShell host.
Invoke-Sqlcmd is the PowerShell equivalent of sqlcmd.exe. Instead of text it outputs System.Data.DataRow objects.
The -Query
parameter works like the -Q
parameter of sqlcmd.exe. Pass it a SQL query that describes the data you want to export.
The -Database
parameter works like the -d
parameter of sqlcmd.exe. Pass it the name of the database that contains the data to be exported.
The -Server
parameter works like the -S
parameter of sqlcmd.exe. Pass it the name of the server that contains the data to be exported.
Export-CSV is a PowerShell cmdlet that serializes generic objects to CSV. It ships with PowerShell.
The -NoTypeInformation
parameter suppresses extra output that is not part of the CSV format. By default the cmdlet writes a header with type information. It lets you know the type of the object when you deserialize it later with Import-Csv
, but it confuses tools that expect standard CSV.
The -Path
parameter works like the -o
parameter of sqlcmd.exe. A full path for this value is safest if you are stuck using the old SQLPS module.
The -Encoding
parameter works like the -f
or -u
parameters of sqlcmd.exe. By default Export-Csv outputs only ASCII characters and replaces all others with question marks. Use UTF8 instead to preserve all characters and stay compatible with most other tools.
The main advantage of this solution over sqlcmd.exe or bcp.exe is that you don't have to hack the command to output valid CSV. The Export-Csv cmdlet handles it all for you.
The main disadvantage is that Invoke-Sqlcmd
reads the whole result set before passing it along the pipeline. Make sure you have enough memory for the whole result set you want to export.
It may not work smoothly for billions of rows. If that's a problem, you could try the other tools, or roll your own efficient version of Invoke-Sqlcmd
using System.Data.SqlClient.SqlDataReader class.

you can also do this:

new_section = "Sec_%s" % section
This allows you not only append, but also insert wherever in the string:

I would definitely use html markers to achieve this. Just surround your text with <p></p>
or <font></font>
and add the desired attributes. See the following example:
<p style="font-family: times, serif; font-size:11pt; font-style:italic">
Why did we use these specific parameters during the calculation of the fingerprints?
</p>
This will produce the following output
compared to
This would work with Jupyter Notebook as well as Typora, but I'm not sure if it is universal.
Lastly, be aware that the html marker overrides the font styling used by Markdown.
I recently had some issues with a VirtualHost. I used a2ensite
to enable a host but before running a restart (which would kill the server on fail) I ran
apache2ctl -S
Which gives you some info about what's going on with your virtual hosts. It's not perfect, but it helps.
You can make the application fully compatible with the date and time that is used by MySql. When the application runs at runtime provide this code. First Go to the Application Events. In the list of tools

I think below query will be helpful to split FirstName and LastName from FullName even if there is only FirstName. For example: 'Philip John' can be split into Philip and John. But if there is only Philip, because of the charIndex of Space is 0, it will only give you ''.
Try the below one.
declare @FullName varchar(100)='Philp John'
Select
LTRIM(RTRIM(SUBSTRING(@FullName, 0, CHARINDEX(' ', @FullName+' ')))) As FirstName
, LTRIM(RTRIM(SUBSTRING(@FullName, CHARINDEX(' ', @FullName+' ')+1, 8000)))As LastName
Hope this will help you. :)

In C++ the stack memory is where local variables get stored/constructed. The stack is also used to hold parameters passed to functions.
The stack is very much like the std::stack class: you push parameters onto it and then call a function. The function then knows that the parameters it expects can be found on the end of the stack. Likewise, the function can push locals onto the stack and pop them off it before returning from the function. (caveat - compiler optimizations and calling conventions all mean things aren't this simple)
The stack is really best understood from a low level and I'd recommend Art of Assembly - Passing Parameters on the Stack. Rarely, if ever, would you consider any sort of manual stack manipulation from C++.
Generally speaking, the stack is preferred as it is usually in the CPU cache, so operations involving objects stored on it tend to be faster. However the stack is a limited resource, and shouldn't be used for anything large. Running out of stack memory is called a Stack buffer overflow. It's a serious thing to encounter, but you really shouldn't come across one unless you have a crazy recursive function or something similar.
Heap memory is much as rskar says. In general, C++ objects allocated with new, or blocks of memory allocated with the likes of malloc end up on the heap. Heap memory almost always must be manually freed, though you should really use a smart pointer class or similar to avoid needing to remember to do so. Running out of heap memory can (will?) result in a std::bad_alloc.
.c_str()
returns a const char*
. If you need a mutable version, you will need to produce a copy yourself.
Here is a way to do this. (Personally I would not do it this way, but thought it was a fun way to do it for an example)
function intDivide(numerator, denominator) {
return parseInt((numerator/denominator).toString().split(".")[0]);
}
let x = intDivide(4,5);
let y = intDivide(5,5);
let z = intDivide(6,5);
console.log(x);
console.log(y);
console.log(z);

You can use pure Python to do it:
import json
list = [1, 2, (3, 4)] # Note that the 3rd element is a tuple (3, 4)
json.dumps(list) # '[1, 2, [3, 4]]'
Do not use regular expressions to parse HTML.
But if you ever need to find all regexp matches in a string, use the findall
function.
import re
line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
matches = re.findall('<form>(.*?)</form>', line, re.DOTALL)
print(matches)
# Output: ['Form 1', 'Form 2']
There is a difference in performance.
Simply put HS256
is about 1 order of magnitude faster than RS256
for verification but about 2 orders of magnitude faster than RS256
for issuing (signing).
640,251 91,464.3 ops/s
86,123 12,303.3 ops/s (RS256 verify)
7,046 1,006.5 ops/s (RS256 sign)

exec('wget http://<url to the php script>')
worked for me.
It enable me to integrate two php files that were designed as web pages and run them as code to do work without affecting the calling page
# Problem: Given c1 and c2:
c1 = [1, 6, 7, 10, 13, 28, 32, 41, 58, 63]
c2 = [[13, 17, 18, 21, 32], [7, 11, 13, 14, 28], [1, 5, 6, 8, 15, 16]]
# how do you get c3 to be [[13, 32], [7, 13, 28], [1, 6]] ?
Here's one way to set c3
that doesn't involve sets:
c3 = []
for sublist in c2:
c3.append([val for val in c1 if val in sublist])
But if you prefer to use just one line, you can do this:
c3 = [[val for val in c1 if val in sublist] for sublist in c2]
It's a list comprehension inside a list comprehension, which is a little unusual, but I think you shouldn't have too much trouble following it.
Primary keys are for uniquely identifying rows. This is done by comparing all parts of a key to the input.
Per definition, NULL cannot be part of a successful comparison. Even a comparison to itself (NULL = NULL
) will fail. This means a key containing NULL would not work.
Additonally, NULL is allowed in a foreign key, to mark an optional relationship.(*) Allowing it in the PK as well would break this.
(*)A word of caution: Having nullable foreign keys is not clean relational database design.
If there are two entities A
and B
where A
can optionally be related to B
, the clean solution is to create a resolution table (let's say AB
). That table would link A
with B
: If there is a relationship then it would contain a record, if there isn't then it would not.
setTimeout
is a kind of Thread, it holds a operation for a given time and execute.
setTimeout(function,time_in_mills);
in here the first argument should be a function type; as an example if you want to print your name after 3 seconds, your code should be something like below.
setTimeout(function(){console.log('your name')},3000);
Key point to remember is, what ever you want to do by using the setTimeout
method, do it inside a function. If you want to call some other method by parsing some parameters, your code should look like below:
setTimeout(function(){yourOtherMethod(parameter);},3000);
Use String.Format with alignment values.
For example:
String.Format("|{0,5}|{1,5}|{2,5}|{3,5}|", arg0, arg1, arg2, arg3);
To create one formatted row.
public static Map <String, String> parseQueryString (final URL url)

final StringTokenizer parts = new StringTokenizer (pair, "=");
final String name = URLDecoder.decode (parts.nextToken (), "ISO-8859-1");
final String value = URLDecoder.decode (parts.nextToken (), "ISO-8859-1");
qps.put (name, value);

Add a label=

y1 = np.sin(x)
y2 = np.cos(x)
plt.plot(x, y1, "-b", label="sine")
plt.plot(x, y2, "-r", label="cosine")
plt.legend(loc="upper left")
plt.ylim(-1.5, 2.0)
plt.show()

In the end I decided to use the format YYYYMMDD
in all CSV files, which doesn't convert to date in Excel, but can be read by all our applications correctly.
I'm not sure this is a right way but I solved it by adding display: inline-block;
to the wrapper div.
#wrapper{
display: inline-block;
/*border: 1px black solid;*/
width: 75%;
min-width: 800px;
}
.content{
text-align: justify;
float: right;
width: 90%;
}
.lbar{
text-align: justify;
float: left;
width: 10%;
}
I see that this is answered already, but I believe I have a simple jQuery solution ( jQuery is not even really needed; I just enjoy using it ):
I suggest counting the line breaks in the textarea
text and setting the rows
attribute of the textarea
accordingly.
var text = jQuery('#your_textarea').val(),
// look for any "\n" occurences
matches = text.match(/\n/g),
breaks = matches ? matches.length : 2;
jQuery('#your_textarea').attr('rows',breaks + 2);
I will provide with a more elegant and robust way as follows, using unpacking:
def mark_last(iterable):
try:
*init, last = iterable
except ValueError: # if iterable is empty
return
for e in init:
yield e, True
yield last, False
Test:
for a, b in mark_last([1, 2, 3]):
print(a, b)
The result is:
1 True
2 True
3 False

}
DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);
assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.
The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.
As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.
If you need to parse other formats, you can check out the Standard DateTime Format Strings.
