Easier update:
Use field.selectionStart
example in this answer.
Thanks to @commonSenseCode for pointing this out.
Old answer:
Found this solution. Not jquery based but there is no problem to integrate it to jquery:
/*
** Returns the caret (cursor) position of the specified text field (oField).
** Return value range is 0-oField.value.length.
*/
function doGetCaretPosition (oField) {
// Initialize
var iCaretPos = 0;
// IE Support
if (document.selection) {
// Set focus on the element
oField.focus();
// To get cursor position, get empty selection range
var oSel = document.selection.createRange();
// Move selection start to 0 position
oSel.moveStart('character', -oField.value.length);
// The caret position is selection length
iCaretPos = oSel.text.length;
}
// Firefox support
else if (oField.selectionStart || oField.selectionStart == '0')
iCaretPos = oField.selectionDirection=='backward' ? oField.selectionStart : oField.selectionEnd;
// Return results
return iCaretPos;
}
I was just working through this problem, and none of these solutions would work for me. I couldn't use the EmptyDataTemplate
property because I was creating my GridView
dynamically with custom fields which provide filters in the headers. I couldn't use the example almny posted because I'm using ObjectDataSource
s instead of DataSet
or DataTable
. However, I found this answer posted on another StackOverflow question, which links to this elegant solution that I was able to make work for my particular situation. It involves overriding the CreateChildControls
method of the GridView
to create the same header row that would have been created had there been real data. I thought it worth posting here, where it's likely to be found by other people in a similar fix.
As of Jquery 3.0 and above .bind has been deprecated and they prefer using .on instead. As @Blazemonger answered earlier that it may be removed and its for sure that it will be removed. For the older versions .bind would also call .on internally and there is no difference between them. Please also see the api for more detail.
In the simplest terms, git pull
does a git fetch
followed by a git merge
.
You can do a git fetch
at any time to update your remote-tracking branches under refs/remotes/<remote>/
.
This operation never changes any of your own local branches under refs/heads
, and is safe to do without changing your working copy. I have even heard of people running git fetch
periodically in a cron job in the background (although I wouldn't recommend doing this).
A git pull
is what you would do to bring a local branch up-to-date with its remote version, while also updating your other remote-tracking branches.
From the Git documentation for git pull:
In its default mode,
git pull
is shorthand forgit fetch
followed bygit merge FETCH_HEAD
.
Set the property RetainSameConnection
on the Connection Manager
to True
so that temporary table created in one Control Flow task can be retained in another task.
Here is a sample SSIS package written in SSIS 2008 R2
that illustrates using temporary tables.
Create a stored procedure that will create a temporary table named ##tmpStateProvince
and populate with few records. The sample SSIS package will first call the stored procedure and then will fetch the temporary table data to populate the records into another database table. The sample package will use the database named Sora
Use the below create stored procedure script.
USE Sora;
GO
CREATE PROCEDURE dbo.PopulateTempTable
AS
BEGIN
SET NOCOUNT ON;
IF OBJECT_ID('TempDB..##tmpStateProvince') IS NOT NULL
DROP TABLE ##tmpStateProvince;
CREATE TABLE ##tmpStateProvince
(
CountryCode nvarchar(3) NOT NULL
, StateCode nvarchar(3) NOT NULL
, Name nvarchar(30) NOT NULL
);
INSERT INTO ##tmpStateProvince
(CountryCode, StateCode, Name)
VALUES
('CA', 'AB', 'Alberta'),
('US', 'CA', 'California'),
('DE', 'HH', 'Hamburg'),
('FR', '86', 'Vienne'),
('AU', 'SA', 'South Australia'),
('VI', 'VI', 'Virgin Islands');
END
GO
Create a table named dbo.StateProvince
that will be used as the destination table to populate the records from temporary table. Use the below create table script to create the destination table.
USE Sora;
GO
CREATE TABLE dbo.StateProvince
(
StateProvinceID int IDENTITY(1,1) NOT NULL
, CountryCode nvarchar(3) NOT NULL
, StateCode nvarchar(3) NOT NULL
, Name nvarchar(30) NOT NULL
CONSTRAINT [PK_StateProvinceID] PRIMARY KEY CLUSTERED
([StateProvinceID] ASC)
) ON [PRIMARY];

Quite simply:
git rm --cached <file>
makes git stop tracking the file completely (leaving it in the filesystem, unlike plain git rm
*)git reset HEAD <file>
unstages any modifications made to the file since the last commit (but doesn't revert them in the filesystem, contrary to what the command name might suggest**). The file remains under revision control.If the file wasn't in revision control before (i.e. you're unstaging a file that you had just git add
ed for the first time), then the two commands have the same effect, hence the appearance of these being "two ways of doing something".
* Keep in mind the caveat @DrewT mentions in his answer, regarding git rm --cached
of a file that was previously committed to the repository. In the context of this question, of a file just added and not committed yet, there's nothing to worry about.
** I was scared for an embarrassingly long time to use the git reset command because of its name -- and still today I often look up the syntax to make sure I don't screw up. (update: I finally took the time to summarize the usage of git reset
in a tldr page, so now I have a better mental model of how it works, and a quick reference for when I forget some detail.)
Here's how I solved that problem:
int pHeight = picture.getHeight();
int pWidth = picture.getWidth();
int vWidth = preview.getWidth();
preview.getLayoutParams().height = (int)(vWidth*((double)pHeight/pWidth));
preview - imageView with width setted to "match_parent" and scaleType to "cropCenter"
picture - Bitmap object to set in imageView src.
That's works pretty well for me.
You could also simply link both cells, and have an =Cell formula in each column like, =Sheet2!A2
in Sheet 1 A2 and =Sheet2!B2
in Sheet 1 B2, and drag it down, and then sort those two columns the way you want.
This would be better if your unique items change also, then all you would do is sort and be done.
You have to get back out of the Iframe with the following code:
driver.switchTo().frame(driver.findElement(By.id("frameId")));
//do your stuff
driver.switchTo().defaultContent();
hope that helps
For a Table:
SELECT
TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
REFERENCED_TABLE_SCHEMA = '<database>' AND
REFERENCED_TABLE_NAME = '<table>';
For a Column:
SELECT
TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
REFERENCED_TABLE_SCHEMA = '<database>' AND
REFERENCED_TABLE_NAME = '<table>' AND
REFERENCED_COLUMN_NAME = '<column>';
Basically, we changed REFERENCED_TABLE_NAME with REFERENCED_COLUMN_NAME in the where clause.
Use this:
SELECT * FROM Table WHERE Column LIKE '%[0-9]%'
There is a fairly simple answer with powershell.
Import-PfxCertificate -Password $secure_pw -CertStoreLocation Cert:\LocalMachine\Root -FilePath certs.pfx
The trick is making a "secure" password...
$plaintext_pw = 'PASSWORD';
$secure_pw = ConvertTo-SecureString $plaintext_pw -AsPlainText -Force;
Import-PfxCertificate -Password $secure_pw -CertStoreLocation Cert:\LocalMachine\Root -FilePath certs.pfx;
We could type our variable with an explicit return type:
const script: HTMLScriptElement = document.getElementsByName(id).item(0);
Or assert as (needed with TSX):
const script = document.getElementsByName(id).item(0) as HTMLScriptElement;
Or in simpler cases assert with angle-bracket syntax.
A type assertion is like a type cast in other languages, but performs no special checking or restructuring of data. It has no runtime impact, and is used purely by the compiler.
Documentation:
For use in a /etc/hosts
file as a simple ad blocking technique to cause a domain to fail to resolve, the 0.0.0.0 address has been widely used because it causes the request to immediately fail without even trying, because it's not a valid or routable address. This is in comparison to using 127.0.0.1 in that place, where it will at least check to see if your own computer is listening on the requested port 80 before failing with 'connection refused.' Either of those addresses being used in the hosts file for the domain will stop any requests from being attempted over the actual network, but 0.0.0.0 has gained favor because it's more 'optimal' for the above reason. "127" IPs will attempt to hit your own computer, and any other IP will cause a request to be sent to the router to try to route it, but for 0.0.0.0 there's nowhere to even send a request to.
All that being said, having any IP listed in your hosts file for the domain to be blocked is sufficient, and you wouldn't need or want to also put an ipv6 address in your hosts file unless -- possibly -- you don't have ipv4 enabled at all. I'd be really surprised if that was the case, though. And still though, I think having the host appear in /etc/hosts with a bad ipv4 address when you don't have ipv4 enabled would still give you the result you are looking for which is for it to fail, instead of looking up the real DNS of say, adserver-example.com and getting back either a v4 or v6 IP.

I think that the correct form to insert a value on a specify row is:
UPDATE table SET column = value WHERE columnid = 1
it works, and is similar if you write on Microsoft SQL Server
INSERT INTO table(column) VALUES (130) WHERE id = 1;
on mysql you have to Update the table.
If you want the remainder of your division problem, just use the actual remainder rules, just like in mathematics. Granted this won't give you a decimal output.
valone = 8
valtwo = 3
x = valone / valtwo
r = valone - (valtwo * x)
print "Answer: %s with a remainder of %s" % (x, r)
If you want to make this in a calculator format, just substitute valone = 8
with valone = int(input("Value One"))
. Do the same with valtwo = 3
, but different vairables obviously.
If you have a checkbox in your html something like:
<input id="conducted" type = "checkbox" name="party" value="0">
and you want to add an EventListener to this checkbox using javascript, in your associated js file, you can do as follows:
checkbox = document.getElementById('conducted');
checkbox.addEventListener('change', e => {
if(e.target.checked){
//do something
}
});

The msi
file extension is mapped to msiexec (same way typing a .txt filename on a command prompt launches Notepad/default .txt
file handler to display the file).
Thus typing in a filename with an .msi extension really runs msiexec with the MSI file as argument and takes the default action, install. For that reason, uninstalling requires you to invoke msiexec with uninstall switch to unstall it.
While doing "figure(1), figure(2),..." will solve the problem in most cases, it will not solve them in all cases. Suppose you have a bunch of MATLAB figures on your desktop and how many you have open varies from time to time before you run your code. Using the answers provided, you will overwrite these figures, which you may not want. The easy workaround is to just use the command "figure" before you plot.
Example: you have five figures on your desktop from a previous script you ran and you use
figure(1);
plot(...)
figure(2);
plot(...)
You just plotted over the figures on your desktop. However the code
figure;
plot(...)
figure;
plot(...)
just created figures 6 and 7 with your desired plots and left your previous plots 1-5 alone.
You can use TestSuite
and custom TestCase
classes.
import unittest
class CustomTest(unittest.TestCase):
def __init__(self, name, a, b):
super().__init__()
self.name = name
self.a = a
self.b = b
def runTest(self):
print("test", self.name)
self.assertEqual(self.a, self.b)
if __name__ == '__main__':
suite = unittest.TestSuite()
suite.addTest(CustomTest("Foo", 1337, 1337))
suite.addTest(CustomTest("Bar", 0xDEAD, 0xC0DE))
unittest.TextTestRunner().run(suite)
no, there is no way to make array length dynamic in java. you can use ArrayList
or other List
implementations instead.
def closest(list, Number):
aux = []
for valor in list:
aux.append(abs(Number-valor))
return aux.index(min(aux))
This code will give you the index of the closest number of Number in the list.
The solution given by KennyTM is the best overall, but in the cases you cannot use it (like brython), this function will do the work

If you have created a new Github account and you want to push commits with your new account instead of your previous account then the .gitconfig must be updated, otherwise, you will push with the already owned Github account to the new account.
In order to fix this, you have to navigate to your home directory and open the .gitconfig with an editor. The editor can be vim, notepad++, or even notepad.
Once you have the .gitconfig open, just modify the "name" with your new Github account username that you want to push with.
<form method="POST">
<button name="data" onclick="getData()">Click</button>

If you are drawing on the Graphics of the Control than you should do something draw on the Bitmap everything you are drawing on the canvas, but have in mind that Bitmap needs to be the exact size of the control you are drawing on:
Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width,myControl.ClientRectangle.Height);
Graphics gBmp = Graphics.FromImage(bmp);
gBmp.DrawEverything(); //this is your code for drawing
gBmp.Dispose();
bmp.Save("image.png", ImageFormat.Png);
Or you can use a DrawToBitmap
method of the Control. Something like this:
Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width, myControl.ClientRectangle.Height);
myControl.DrawToBitmap(bmp,new Rectangle(0,0,bmp.Width,bmp.Height));
bmp.Save("image.png", ImageFormat.Png);

what about having the image be something selected by the user? Use a input:file tag and then after they select the image, show it on the clientside webpage? That is doable for most things. Right now i am trying to get it working for IE, but as with all microsoft products, it is a cluster fork().
That's desired behavior, you should define the model in the controller, not in the view.

<input type="text" ng-model="rootFolders">
</div>
function Main($scope) {
$scope.rootFolders = 'bob';
}
Use Hosts Commander. It's simple and powerful. Translated description (from russian) here.
hosts add another.dev 192.168.1.1 # Remote host

hosts disable localhost
...and many others...
Usage:
hosts - run hosts command interpreter
hosts <command> <params> - execute hosts command
Commands:
add <host> <aliases> <addr> # <comment> - add new host
set <host|mask> <addr> # <comment> - set ip and comment for host
rem <host|mask> - remove host
on <host|mask> - enable host
off <host|mask> - disable host
view [all] <mask> - display enabled and visible, or all hosts
hide <host|mask> - hide host from 'hosts view'
show <host|mask> - show host in 'hosts view'
print - display raw hosts file
format - format host rows
clean - format and remove all comments
rollback - rollback last operation
backup - backup hosts file
restore - restore hosts file from backup
recreate - empty hosts file
open - open hosts file in notepad
To install within your Docker container you can run command
docker exec apt-get update && apt-get install -y vim
But this will be limited to the container in which vim is installed. To make it available to all the containers, edit the Dockerfile and add
RUN apt-get update && apt-get install -y vim
or you can also extend the image in the new Dockerfile and add above command. Eg.
FROM < image name >
RUN apt-get update && apt-get install -y vim
Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....
Ok. So finally I was able to log the post data and return a 200. It's kind of a hacky solution that I'm not too proud of which basically overrides the natural behavior for error_page, but my inexperience of nginx plus timelines lead me to this solution:
location /bk {
if ($request_method != POST) {
return 405;
}
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_redirect off;
proxy_pass $scheme://127.0.0.1:$server_port/success;
log_format my_tracking $request_body;
access_log /mnt/logs/nginx/my_tracking.access.log my_tracking;
}
location /success {
return 200;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/www/nginx-default;
log_format my_tracking $request_body;
access_log /mnt/logs/nginx/my_tracking.access.log my_tracking_2;
}
Now according to that config, it would seem that the proxy pass would return a 200 all the time. Occasionally I would get 500 but when I threw in an error_log to see what was going on, all of my request_body data was in there and I couldn't see a problem. So I caught that and wrote to the same log. Since nginx doesn't like the same name for the tracking variable, I just used my_tracking_2 and wrote to the same log as when it returns a 200. Definitely not the most elegant solution and I welcome any better solution. I've seen the post module, but in my scenario, I couldn't recompile from source.

R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat
.
y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab: , newline:
## , unicode point: €
Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1
To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.
grepl("\\[", "a[b")
## [1] TRUE
To match backslashes, you need to double escape, resulting in four backslashes.
grepl("\\\\", c("a\\b", "a\nb"))
## [1] TRUE FALSE
The rebus
package contains constants for each of the special characters to save you mistyping slashes.
library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"
For more examples see:
?SpecialCharacters
Your problem can be solved this way:
library(rebus)
grepl(OPEN_BRACKET, "a[b")
You can also wrap the special characters in square brackets to form a character class.
grepl("[?]", "a?b")
## [1] TRUE
Two of the special characters have special meaning inside character classes: \
and ^
.
Backslash still needs to be escaped even if it is inside a character class.
grepl("[\\\\]", c("a\\b", "a\nb"))
## [1] TRUE FALSE
Caret only needs to be escaped if it is directly after the opening square bracket.
grepl("[ ^]", "a^b") # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b")
## [1] TRUE
rebus
also lets you form a character class.
char_class("?")
## <regex> [?]
If you want to match all punctuation, you can use the [:punct:]
character class.
grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE
stringi
maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.
stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1] TRUE TRUE TRUE TRUE TRUE FALSE FALSE
You can also use the cross-platform syntax for accessing a UGC.
stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1] TRUE TRUE TRUE TRUE TRUE FALSE FALSE
Placing characters between \\Q
and \\E
makes the regular expression engine treat them literally rather than as regular expressions.
grepl("\\Q.\\E", "a.b")
## [1] TRUE
rebus
lets you write literal blocks of regular expressions.
literal(".")
## <regex> \Q.\E
Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:
grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")
A similar option in Sublime Text is the built in Edit->Line->Reindent
. You can put this code in Preferences -> Key Bindings User
:
{ "keys": ["alt+shift+f"], "command": "reindent"}
I use alt+shift+f because I'm a Netbeans user.
To format your code, select all by pressing ctrl+a and "your key combination". Excuse me for my bad english.
Or if you don't want to select all before formatting, add an argument to the command instead:
{ "keys": ["alt+shift+f"], "command": "reindent", "args": {"single_line": false} }

-moz-device-pixel-ratio
Gives the number of device pixels per CSS pixel.
this is almost self-explaining. the number describes the ratio of how much "real" pixels (physical pixerls of the screen) are used to display one "virtual" pixel (size set in CSS).

I don't mention basics like syntax highlighting as I expect these by default.
This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.
PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?
We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments
Here are some links you can read what Java supports
Encrypting/decrypting a data stream.
This example demonstrates how to encrypt (using a symmetric encryption algorithm such as AES, Blowfish, RC2, 3DES, etc) a large amount of data. The data is passed in chunks to one of the encrypt methods: EncryptBytes, EncryptString, EncryptBytesENC, or EncryptStringENC. (The method name indicates the type of input (string or byte array) and the return type (encoded string or byte array). The FirstChunk and LastChunk properties are used to indicate whether a chunk is the first, middle, or last in a stream to be encrypted. By default, both FirstChunk and LastChunk equal true -- meaning that the data passed is the entire amount.
Nick Vogt at H3XED posted this syntax: https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080
Take this link and replace the expression "VIDEOID" with the (shortened/shared) ID of the video.
Exapmple for ID: i3jNECZ3ybk looks like this: ... /v/i3jNECZ3ybk?version=3&vq=hd1080
What you get as a result is the standalone 1080p video but not in the Tube environment.
In my case, the emulator was working with Oreo and lower, but not with Pie, and everything I tried seemed to have no effect. What finally worked was updating the emulator to latest (version 28).
The biggest clue is the rows are all being returned on one line. This indicates line terminators are being ignored or are not present.
You can specify the line terminator for csv_reader. If you are on a mac the lines created will end with \r
rather than the linux standard \n
or better still the suspenders and belt approach of windows with \r\n
.
pandas.read_csv(filename, sep='\t', lineterminator='\r')
You could also open all your data using the codecs package. This may increase robustness at the expense of document loading speed.
import codecs
doc = codecs.open('document','rU','UTF-16') #open for reading with "universal" type set
df = pandas.read_csv(doc, sep='\t')
The proper way to do it is using the ng-options
directive. The HTML would look like this.
<select ng-model="selectedTestAccount"
ng-options="item.Id as item.Name for item in testAccounts">
<option value="">Select Account</option>
</select>
JavaScript:
angular.module('test', []).controller('DemoCtrl', function ($scope, $http) {
$scope.selectedTestAccount = null;
$scope.testAccounts = [];
$http({
method: 'GET',
url: '/Admin/GetTestAccounts',
data: { applicationId: 3 }
}).success(function (result) {
$scope.testAccounts = result;
});
});
You'll also need to ensure angular is run on your html and that your module is loaded.
<html ng-app="test">
<body ng-controller="DemoCtrl">
....
</body>
</html>
Do the simple things first.
Check that part of your solution is not locked by a running process.
For instance, I ran "InstallUtil ' on my windows service(which I normally unit test from a console).
This locked some of my dlls in the bin folder of the windows service project. When I did a rebuild I got the exception in this issue.
I stopped the windows service, rebuilt and it succeeded.
Check Windows Task Manager for your Application, before doing any of the advance steps in this issue.
So when you hear footsteps, think horses not zebras! (from medical student friend)
For ListView item image you can set ImageView.setVisibility(View.INVISIBLE)
or ImageView.setImageBitmap(null)
in list adapter for "no image" case.
I would recommend taking a look at jQuery UI autocomplete widget. They handled most of the cases there since their code base is more mature than most ones out there.
Below is a link to a demo page so you can verify it works. http://jqueryui.com/demos/autocomplete/#default
You will get the most benefit from reading the source and seeing how they solved it. You can find it here: https://github.com/jquery/jquery-ui/blob/master/ui/jquery.ui.autocomplete.js.
Basically they do it all, they bind to input, keydown, keyup, keypress, focus and blur
. Then they have special handling for all sorts of keys like page up, page down, up arrow key and down arrow key
. A timer is used before getting the contents of the textbox. When a user types a key that does not correspond to a command (up key, down key and so on) there is a timer that explorers the content after about 300 milliseconds. It looks like this in the code:
// switch statement in the
switch( event.keyCode ) {
//...
case keyCode.ENTER:
case keyCode.NUMPAD_ENTER:
// when menu is open and has focus
if ( this.menu.active ) {
// #6055 - Opera still allows the keypress to occur
// which causes forms to submit
suppressKeyPress = true;
event.preventDefault();
this.menu.select( event );
}
break;
default:
suppressKeyPressRepeat = true;
// search timeout should be triggered before the input value is changed
this._searchTimeout( event );
break;
}
// ...
// ...
_searchTimeout: function( event ) {
clearTimeout( this.searching );
this.searching = this._delay(function() { // * essentially a warpper for a setTimeout call *
// only search if the value has changed
if ( this.term !== this._value() ) { // * _value is a wrapper to get the value *
this.selectedItem = null;
this.search( null, event );
}
}, this.options.delay );
},
The reason to use a timer is so that the UI gets a chance to be updated. When Javascript is running the UI cannot be updated, therefore the call to the delay function. This works well for other situations such as keeping focus on the textbox (used by that code).
So you can either use the widget or copy the code into your own widget if you are not using jQuery UI (or in my case developing a custom widget).
Swift 3
I had this keep coming up as a newbie and found that present loads modal views that can be dismissed but switching to root controller is best if you don't need to show a modal.
I was using this
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard?.instantiateViewController(withIdentifier: "MainAppStoryboard") as! TabbarController
present(vc, animated: false, completion: nil)
Using this instead with my tabController:
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let view = storyboard.instantiateViewController(withIdentifier: "MainAppStoryboard") as UIViewController
let appDelegate = UIApplication.shared.delegate as! AppDelegate
//show window
appDelegate.window?.rootViewController = view
Just adjust to a view controller if you need to switch between multiple storyboard screens.
Or just in GlobalConstants.swift:
import Foundation
let someNotification = "aaaaNotification"
As said before, List
provides functionality to add elements in a clean way, to do the same with arrays, you have to resize them to accomodate extra elements, see code below:
int[] arr = new int[2];
arr[0] = 1;
arr[1] = 2;
//without this line we'd get a exception
Array.Resize(ref arr, 3);
arr[2] = 3;
Regarding your idea with loop:
elements of an array are set to their default values when array is initialized. So your approach would be good, if you want to fill "blanks" in array holding reference types (which have default value null
).
But it wouldn't work with value types, as they are initialized with 0
!
Yes. You Can.
You can increase your heap memory to 75% of physical memory (6 GB Heap) or higher.
Since You are using 64bit you can increase your heap size to your desired amount. In Case you are using 32bit it is limited to 4GB.
$ java -Xms512m -Xmx6144m JavaApplication
Sets you with initial heap size to 512mb and maximum heapsize to 6GB.
Hope it Helps.. :)
Try entering the url inside the function
$location.url('http://www.google.com')
The key is to give the anchor links a display property of "block" and a width property of 100%.
Making list-items clickable (example):
HTML:
<ul>
<li><a href="">link1</a></li>
<li><a href="">link2</a></li>
<li><a href="">link3</a></li>
</ul>
CSS:
ul {
list-style-type: none;
margin: 0;
padding: 0;
}
ul li a {
display: block;
width: 100%;
text-decoration: none;
padding: 5px;
}
ul li a:hover {
background-color: #ccc;
}
Just put the following code on the top of the page
@{

}
If you need to fetch an object's property dynamically, use the getattr() function: getattr(user, "fullName")
- or to elaborate:
user = User()
property = "fullName"
name = getattr(user, property)
Otherwise just use user.fullName
.
If you want to also allow alphanumeric characters which don't belong to the ascii characters set, like for instance german umlaut's, you can consider using the following solution:
String value = "your value";
// this could be placed as a static final constant, so the compiling is only done once
Pattern pattern = Pattern.compile("[^\\w]", Pattern.UNICODE_CHARACTER_CLASS);
value = pattern.matcher(value).replaceAll("");
Please note that the usage of the UNICODE_CHARACTER_CLASS flag could have an impose on performance penalty (see javadoc of this flag)
My take:
#!/usr/bin/env python3
import pkg_resources
dists = [str(d).replace(" ","==") for d in pkg_resources.working_set]
for i in dists:
print(i)
Full answer to the original question that was talking about a possible different path on local and remote is below
git fetch origin
git diff master -- [local-path] origin/master -- [remote-path]
Assuming the local path is docs/file1.txt and remote path is docs2/file1.txt, use git diff master -- docs/file1.txt origin/master -- docs2/file1.txt
This is adapted from GitHub help page here and Code-Apprentice answer above
I think it's better to always use ApplicationContext, unless you're in a mobile environment like someone else said already. ApplicationContext has more functionality and you definitely want to use the PostProcessors such as RequiredAnnotationBeanPostProcessor, AutowiredAnnotationBeanPostProcessor and CommonAnnotationBeanPostProcessor, which will help you simplify your Spring configuration files, and you can use annotations such as @Required, @PostConstruct, @Resource, etc in your beans.
Even if you don't use all the stuff ApplicationContext offers, it's better to use it anyway, and then later if you decide to use some resource stuff such as messages or post processors, or the other schema to add transactional advices and such, you will already have an ApplicationContext and won't need to change any code.
If you're writing a standalone app, load the ApplicationContext in your main method, using a ClassPathXmlApplicationContext, and get the main bean and invoke its run() (or whatever method) to start your app. If you're writing a web app, use the ContextLoaderListener in web.xml so that it creates the ApplicationContext and you can later get it from the ServletContext, regardless of whether you're using JSP, JSF, JSTL, struts, Tapestry, etc.
Also, remember you can use multiple Spring configuration files and you can either create the ApplicationContext by listing all the files in the constructor (or listing them in the context-param for the ContextLoaderListener), or you can just load a main config file which has import statements. You can import a Spring configuration file into another Spring configuration file by using <import resource="otherfile.xml" /> which is very useful when you programmatically create the ApplicationContext in the main method and load only one Spring config file.
Update:
You can actually "break" by throwing an error inside and catching it outside: something like this:
try{
_([1,2,3]).each(function(v){
if (v==2) throw new Error('break');
});
}catch(e){
if(e.message === 'break'){
//break successful
}
}
This obviously has some implications regarding any other exceptions that your code trigger in the loop, so use with caution!
using System.Text.RegularExpressions;
string str = Regex.Replace(HttpUtility.HtmlDecode(HTMLString), "<.*?>", string.Empty);
I had the same problem and I found out that if you add the URL param ?v=3
you won't get the warning message anymore:
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3"></script>
As pointed out in the comments by @Zia Ul Rehman Mughal
Turns out specifying this means you are referring to old frozen version 3.0 not the latest version. Frozen old versions are not updated with bug fixes or anything. But this is good to mention though. https://developers.google.com/maps/documentation/javascript/versions#the-frozen-version
This solution doesn't work anymore.
I have tried for several times after I set git buffer, as I mentioned in the question, it seems work now.
So if you met this error, run this command:
git config --global http.postBuffer 2M
and then try again for some times.
Reference:
You can loop through all directories including hidden directrories (beginning with a dot) with:
for file in */ .*/ ; do echo "$file is a directory"; done
note: using the list */ .*/
works in zsh only if there exist at least one hidden directory in the folder. In bash it will show also .
and ..
Another possibility for bash to include hidden directories would be to use:
shopt -s dotglob;
for file in */ ; do echo "$file is a directory"; done
If you want to exclude symlinks:
for file in */ ; do
if [[ -d "$file" && ! -L "$file" ]]; then
echo "$file is a directory";
fi;
done
To output only the trailing directory name (A,B,C as questioned) in each solution use this within the loops:
file="${file%/}" # strip trailing slash
file="${file##*/}" # strip path and leading slash
echo "$file is the directoryname without slashes"
mkdir /tmp/A /tmp/B /tmp/C "/tmp/ dir with spaces"
for file in /tmp/*/ ; do file="${file%/}"; echo "${file##*/}"; done
What you need is properly a service:
.factory('DataLayer', ['$http',
function($http) {
var factory = {};
var locations;
factory.getLocations = function(success) {
if(locations){
success(locations);
return;
}
$http.get('locations/locations.json').success(function(data) {
locations = data;
success(locations);
});
};
return factory;
}
]);
The locations
would be cached in the service which worked as singleton model. This is the right way to fetch data.
Use this service DataLayer
in your controller and directive is ok as following:
appControllers.controller('dummyCtrl', function ($scope, DataLayer) {
DataLayer.getLocations(function(data){
$scope.locations = data;
});
});
.directive('map', function(DataLayer) {
return {
restrict: 'E',
replace: true,
template: '<div></div>',
link: function(scope, element, attrs) {
DataLayer.getLocations(function(data) {
angular.forEach(data, function(location, key){
//do something
});
});
}
};
});
If you are writing a function, which is always preferred, you should propagate the error like this:
function() {
if some_command; then
echo worked
else
return $?
fi
}
This will propagate the error to the caller, so that he can do things like function && next
as expected.
If you have constant URL
I recommend use simplified http-request built on apache http.
You can build your client as following:
private filan static HttpRequest<YourResponseType> httpRequest =
HttpRequestBuilder.createGet(yourUri,YourResponseType)
.build();
public void send(){
ResponseHendler<YourResponseType> rh =
httpRequest.execute(param1, value1, param2, value2);
handler.ifSuccess(this::whenSuccess).otherwise(this::whenNotSuccess);
}
public void whenSuccess(ResponseHendler<YourResponseType> rh){
rh.ifHasContent(content -> // your code);
}
public void whenSuccess(ResponseHendler<YourResponseType> rh){
LOGGER.error("Status code: " + rh.getStatusCode() + ", Error msg: " + rh.getErrorText());
}
Note: There are many useful methods to manipulate your response.
I'm not sure what you're trying to do: If you added the file via
svn add myfile
you only told svn to put this file into your repository when you do your next commit. There's no change to the repository before you type an
svn commit
If you delete the file before the commit, svn
has it in its records (because you added it) but cannot send it to the repository because the file no longer exist.
So either you want to save the file in the repository and then delete it from your working copy: In this case try to get your file back (from the trash?), do the commit and delete the file afterwards via
svn delete myfile
svn commit
If you want to undo the add
and just throw the file away, you can to an
svn revert myfile
which tells svn
(in this case) to undo the add-Operation.
EDIT
Sorry, I wasn't aware that you're using the "Versions" GUI client for Max OSX. So either try a revert on the containing directory using the GUI or jump into the cold water and fire up your hidden Mac command shell :-) (it's called "Terminal" in the german OSX, no idea how to bring it up in the english version...)
All of this can easily be acheived in the xaml by adding the following code in the grid
<Grid>
<Grid.Background>
<ImageBrush ImageSource="/MyProject;component/Images/bg.png"/>
</Grid.Background>
</Grid>
Left for you to do, is adding a folder to the solution called 'Images' and adding an existing file to your new 'Images' folder, in this case called 'bg.png'
Try -
var monthNames = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
var newDate = new Date(form.startDate.value);
var formattedDate = monthNames[newDate.getMonth()] + ' ' + newDate.getFullYear();
To diagnose better, you can capture the standard output and standard error streams of the external program, in order to see what output was generated and why it might not be running as expected.
Look up:
If you set each of those to true, then you can later call process.StandardOutput.ReadToEnd()
and process.StandardError.ReadToEnd()
to get the output into string variables, which you can easily inspect under the debugger, or output to trace or your log file.
I think this will do:
$('#'+div_id+' .widget-head > span').text("new dialog title");
Isn't this the normal way to free the memory associated with an object?
This is a common way of managing dynamically allocated memory, but it's not a good way to do so. This sort of code is brittle because it is not exception-safe: if an exception is thrown between when you create the object and when you delete it, you will leak that object.
It is far better to use a smart pointer container, which you can use to get scope-bound resource management (it's more commonly called resource acquisition is initialization, or RAII).
As an example of automatic resource management:
void test()
{
std::auto_ptr<Object1> obj1(new Object1);
} // The object is automatically deleted when the scope ends.
Depending on your use case, auto_ptr
might not provide the semantics you need. In that case, you can consider using shared_ptr
.
As for why your program crashes when you delete the object, you have not given sufficient code for anyone to be able to answer that question with any certainty.
Sounds like you just need a UINavigationController
setup?
You can get the AppDelegate
anywhere in the program via
YourAppDelegateName* blah = (YourAppDelegateName*)[[UIApplication sharedApplication]delegate];
In your app delegate you should have your navigation controller setup, either via IB or in code.
In code, assuming you've created your 'House overview' viewcontroller already it would be something like this in your AppDelegate
didFinishLaunchingWithOptions
...
self.m_window = [[[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds] autorelease];
self.m_navigationController = [[[UINavigationController alloc]initWithRootViewController:homeViewController]autorelease];
[m_window addSubview:self.m_navigationController.view];
After this you just need a viewcontroller per 'room' and invoke the following when a button click event is picked up...
YourAppDelegateName* blah = (YourAppDelegateName*)[[UIApplication sharedApplication]delegate];
[blah.m_navigationController pushViewController:newRoomViewController animated:YES];
I've not tested the above code so forgive any syntax errors but hope the pseudo code is of help...
I thought I'd try code this up for fun:
graph = {
'1': ['2', '3', '4'],

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)
From RFC 2818 (Section 3.1):
If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.
[...]
In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.
Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).
If you're using keytool
, as of Java 7, keytool
has an option to include a Subject Alternative Name (see the table in the documentation for -ext
): you could use -ext san=dns:www.example.com
or -ext san=ip:10.0.0.1
.
EDIT:
You can request a SAN in OpenSSL by changing openssl.cnf
(it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF
environment variable).
Set the following options (find the appropriate sections within brackets first):
[req]
req_extensions = v3_req
[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com
There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html
The expression between the <%= %> is evaluated before the c:if tag is evaluated. So, supposing that |request.isUserInRole| returns |true|, your example would be evaluated to this first:
<c:if test="true">
<li>user</li>
</c:if>
and then the c:if tag would be executed.
Simple:
if ( $name eq 'tom' && $password eq '123!'
|| $name eq 'frank' && $password eq '321!'
) {
(use the high-precedence &&
and ||
in expressions, reserving and
and or
for flow control, to avoid common precedence errors)
Better:
my %password = (
'tom' => '123!',
'frank' => '321!',
);
if ( exists $password{$name} && $password eq $password{$name} ) {
That error kicks in when you have forgot to include the jQuery library in your page or there is conflict between libraries - for example you be using any other javascript library on your page.
Take a look at this for more info:
Since everybody visiting here is suffering the same thing, I want to share my solution that nobody else has tried before (in this question anyways). I can assure you that it is working, even on a stopped breakpoint which confirms this method.
The issue is to call Service.startForeground(id, notification)
from the service itself, right? Android Framework unfortunately does not guarantee to call Service.startForeground(id, notification)
within Service.onCreate()
in 5 seconds but throws the exception anyway, so I've come up with this way.
Context.startForegroundService()
Context.startForegroundService()
from the service connection and immediately call Service.startForeground()
inside the service connection.Context.bindService()
method inside a try-catch because in some occasions the call can throw an exception, in which case you need to rely on calling Context.startForegroundService()
directly and hope it will not fail. An example can be a broadcast receiver context, however getting application context does not throw an exception in that case, but using the context directly does.This even works when I'm waiting on a breakpoint after binding the service and before triggering the "startForeground" call. Waiting between 3-4 seconds do not trigger the exception while after 5 seconds it throws the exception. (If the device cannot execute two lines of code in 5 seconds, then it's time to throw that in the trash.)
So, start with creating a service connection.
// Create the service connection.
ServiceConnection connection = new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName name, IBinder service)
{
// The binder of the service that returns the instance that is created.
MyService.LocalBinder binder = (MyService.LocalBinder) service;
// The getter method to acquire the service.
MyService myService = binder.getService();
// getServiceIntent(context) returns the relative service intent
context.startForegroundService(getServiceIntent(context));
// This is the key: Without waiting Android Framework to call this method
// inside Service.onCreate(), immediately call here to post the notification.
myService.startForeground(myNotificationId, MyService.getNotification());
// Release the connection to prevent leaks.
context.unbindService(this);
}
@Override
public void onBindingDied(ComponentName name)
{
Log.w(TAG, "Binding has dead.");
}
@Override
public void onNullBinding(ComponentName name)
{
Log.w(TAG, "Bind was null.");
}
@Override
public void onServiceDisconnected(ComponentName name)
{
Log.w(TAG, "Service is disconnected..");
}
};
Inside your service, create a binder that returns the instance of your service.
public class MyService extends Service
{
public class LocalBinder extends Binder
{
public MyService getService()
{
return MyService.this;
}
}
// Create the instance on the service.
private final LocalBinder binder = new LocalBinder();
// Return this instance from onBind method.
// You may also return new LocalBinder() which is
// basically the same thing.
@Nullable
@Override
public IBinder onBind(Intent intent)
{
return binder;
}
}
Then, try to bind the service from that context. If it succeeds, it will call ServiceConnection.onServiceConnected()
method from the service connection that you're using. Then, handle the logic in the code that's shown above. An example code would look like this:
// Try to bind the service
try
{
context.bindService(getServiceIntent(context), connection,
Context.BIND_AUTO_CREATE);
}
catch (RuntimeException ignored)
{
// This is probably a broadcast receiver context even though we are calling getApplicationContext().
// Just call startForegroundService instead since we cannot bind a service to a
// broadcast receiver context. The service also have to call startForeground in
// this case.
context.startForegroundService(getServiceIntent(context));
}
It seems to be working on the applications that I develop, so it should work when you try as well.
you could try using Pandas to retrieve information and get it as dataframe
import pyodbc as cnn
import pandas as pd
cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=SQLSRV01;DATABASE=DATABASE;UID=USER;PWD=PASSWORD')
# Copy to Clipboard for paste in Excel sheet
def copia (argumento):
df=pd.DataFrame(argumento)
df.to_clipboard(index=False,header=True)
tableResult = pd.read_sql("SELECT * FROM YOURTABLE", cnxn)
# Copy to Clipboard
copia(tableResult)
# Or create a Excel file with the results
df=pd.DataFrame(tableResult)
df.to_excel("FileExample.xlsx",sheet_name='Results')
I hope this helps! Cheers!
At least on text inputs, it appears that onChange
is listening for input events:
var event = new Event('input', { bubbles: true });
element.dispatchEvent(event);
I've had this problem after installing the genymotion (another android amulator) plugin. A closer inspection reveled that gradle needs SDK tools version 19.1.0 in order to run (I had 19.0.3 previously).
To fix it, I had to edit build.gradle
and under android
I changed to: buildToolsVersion 19.1.0
Then I had to rebuild again, and the error was gone.
Completely reset?
Delete the .git
directory locally.
Recreate the git repostory:
$ cd (project-directory)
$ git init
$ (add some files)
$ git add .
$ git commit -m 'Initial commit'
Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.
$ git remote add origin <url>
$ git push --force --set-upstream origin master
Sometimes you will get lots of compiler outputs with many warnings and no line of output that says "error: you did something wrong here" but there was still an error. An example of this is a missing header file - the compiler says something like "no such file" but not "error: no such file", then it exits with non-zero exit code some time later (perhaps after many more warnings). Make will bomb out with an error message in these cases!
I didn't use it myself but heard of a simple tool (not a text editor) for this so it is definitely possible without setting up a programming environment (by installing octave or python).
A quick search hints that it was possible with total commander. (A lightweight tool with an easy point and click interface)
I would not be surprised if this still works, but I can't guarantee it.
using sql server 2005, this works for me:
select dateadd(dd,-1,dateadd(mm,datediff(mm,0,YOUR_DATE)+1,0))
Basically, you get the number of months from the beginning of (SQL Server) time for YOUR_DATE. Then add one to it to get the sequence number of the next month. Then you add this number of months to 0 to get a date that is the first day of the next month. From this you then subtract a day to get to the last day of YOUR_DATE.
Html code
<div id="coloredBy">

javascript code
document.getElementById("coloredBy").style.color = colorCode; // red or #ffffff
I think this is very easy to use
The Resource Override extension allows you to do exactly that:
In the case if "Copy Local" is already True, I find it sometimes to work if you remove the files where it has been published to and publish again.
For example if you're using IIS, remove the websites and the contents of the directory to which they are published to, and publish again.
There might be older versions of files at the destination, so to ensure you aren't using older versions, delete everything before publishing again.
I didn't want to have to have the YouTube app present on the device so I used this tutorial:
http://www.viralandroid.com/2015/09/how-to-embed-youtube-video-in-android-webview.html
...to produce this code in my app:
WebView mWebView;
@Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.video_webview);
mWebView=(WebView)findViewById(R.id.videoview);
//build your own src link with your video ID
String videoStr = "<html><body>Promo video<br><iframe width=\"420\" height=\"315\" src=\"https://www.youtube.com/embed/47yJ2XCRLZs\" frameborder=\"0\" allowfullscreen></iframe></body></html>";
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
WebSettings ws = mWebView.getSettings();
ws.setJavaScriptEnabled(true);
mWebView.loadData(videoStr, "text/html", "utf-8");
}
//video_webview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_marginRight="0dp"
android:background="#000000"

android:orientation="vertical" >
<WebView
android:id="@+id/videoview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
This worked just how I wanted it. It doesn't autoplay but the video streams within my app. Worth noting that some restricted videos won't play when embedded.

Replace the components in the square brackets as necessary.
Often the order of the processing does not matter. GNU Parallel is made for this situation:
grep xyz abc.txt | parallel echo do stuff to {}
If you processing is more like:
grep xyz abc.txt | myprogram_reading_from_stdin
and myprogram
is slow then you can run:
grep xyz abc.txt | parallel --pipe myprogram_reading_from_stdin
string str = @"Data Source=HARIHARAN-PC\SQLEXPRESS;Initial Catalog=master;Integrated Security=True" ;
The Collection#filter
method really does eager load all members.
Filtering at the SQL level will be added in doctrine 2.3.
Usually String.Format("format", object) is preferable to object.ToString("format"). Therefore,
String.Format("{0:00000}", 15);
is preferable to,
Key = i.ToString("000000");
An activity populates the ActionBar in its onCreateOptionsMenu()
method.
Instead of using setcustomview()
, just override onCreateOptionsMenu
like this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
return true;
}
If an actions in the ActionBar is selected, the onOptionsItemSelected()
method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menuitem1:
Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
break;
case R.id.menuitem2:
Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
break;
}
return true;
}
JSONArray jsonArray = new JSONArray();
for (loop) {
JSONObject jsonObj= new JSONObject();
jsonObj.put("srcOfPhoto", srcOfPhoto);
jsonObj.put("username", "name"+count);
jsonObj.put("userid", "userid"+count);
jsonArray.put(jsonObj.valueToString());
}
JSONObject parameters = new JSONObject();
parameters.put("action", "remove");
parameters.put("datatable", jsonArray );
parameters.put(Constant.MSG_TYPE , Constant.SUCCESS);
Why were you using an Hashmap if what you wanted was to put it into a JSONObject?
EDIT: As per http://www.json.org/javadoc/org/json/JSONArray.html
EDIT2: On the JSONObject method used, I'm following the code available at: https://github.com/stleary/JSON-java/blob/master/JSONObject.java#L2327 , that method is not deprecated.
We're storing a string representation of the JSONObject, not the JSONObject itself
It is very possible to have multiple versions of glibc on the same system (we do that every day).
However, you need to know that glibc consists of many pieces (200+ shared libraries) which all must match. One of the pieces is ld-linux.so.2, and it must match libc.so.6, or you'll see the errors you are seeing.
The absolute path to ld-linux.so.2 is hard-coded into the executable at link time, and can not be easily changed after the link is done (Update: can be done with patchelf; see this answer below).
To build an executable that will work with the new glibc, do this:
g++ main.o -o myapp ... \
-Wl,--rpath=/path/to/newglibc \
-Wl,--dynamic-linker=/path/to/newglibc/ld-linux.so.2
The -rpath
linker option will make the runtime loader search for libraries in /path/to/newglibc
(so you wouldn't have to set LD_LIBRARY_PATH
before running it), and the -dynamic-linker
option will "bake" path to correct ld-linux.so.2
into the application.
If you can't relink the myapp
application (e.g. because it is a third-party binary), not all is lost, but it gets trickier. One solution is to set a proper chroot
environment for it. Another possibility is to use rtldi and a binary editor. Update: or you can use patchelf.
You should consider to specify SMTP configuration data in config file and do not overwrite them in a code - see SMTP configuration data at http://www.systemnetmail.com/faq/4.1.aspx

the case above is for a new project. I hit upon this error while editing a fork of a well established library.
the typedef was included in the file I was editing but the struct wasn't.
The end result being that I was attempting to edit the struct in the wrong place.
If you run into this in a similar way look for other places where the struct is edited and try it there.
I used to use a custom Makefile that compiled all the files in current directory, but I had to copy it in every directory I needed it, everytime.
So I created my own tool - Universal Compiler which made the process much easier when compile many files.
<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>
That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em'
as the measurement, you may want to use other units, like 'px'
.
EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:
In your HTML page, containing the <p>
tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:
<head>
<style type="text/css">
p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>
So above, all <p>
elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:
<head>
<style type="text/css">
.container p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<div class="container">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</div>
<p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>
In the example above, only the <p>
element inside the div, whose class name is 'container', will have the styles applied - and not the <p>
element outside the container.
In addition to the above, you can collect your styles together and remove the style element from the <head>
tag, replacing it with a <link>
tag, which points to an external CSS file. This external file is where you'd now put your <p>
tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.
Be Careful registering an order with the: X=$(Command)
This one is still executed Even before being called. To check and confirm this, you cand do:
echo test;
X=$(for ((c=0; c<=5; c++)); do
sleep 2;
done);
echo note the 5 seconds elapsed
Include coffee-script in package.json with the specific version required in each project, typically like this:
"dependencies":{
"coffee-script": ">= 1.2.0"
Then run npm install to install dependencies in each project. This will install the specified version of coffee-script which will be accessible locally to each project.
In Place of using this
MsgBox(json.SelectToken("Venue").SelectToken("ID"))
You can also use
MsgBox(json.SelectToken("Venue.ID"))
You have to specify the format (fmt
) of you data in savetxt
, in this case as a string (%s
):
num.savetxt('test.txt', DAT, delimiter=" ", fmt="%s")
The default format is a float, that is the reason it was expecting a float instead of a string and explains the error message.
A single inlined code would be enough for this task. This worked for me effortlessly.
For #android devlopers out there.
String strValue=Objects.requireNonNull(getIntent().getExtras()).getString("string_Key");
res = request.GET['paymentid']
will raise a KeyError
if paymentid
is not in the GET data.
Your sample php code checks to see if paymentid
is in the POST data, and sets $payID
to '' otherwise:
$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''
The equivalent in python is to use the get()
method with a default argument:
payment_id = request.POST.get('payment_id', '')
while debugging, this is what I see in the
response.GET: <QueryDict: {}>
,request.POST: <QueryDict: {}>
It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.
Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.
Rollback normally won't work on these delete functions and surely a backup only can save you.
If there is no backup then there is no way to restore it as delete queries ran on PuTTY,Derby using .sql files are auto committed once you fire the delete query.
Ok Got it, I downloaded a custom concatenation function and then just referenced its cells
Code
Function concat(useThis As Range, Optional delim As String) As String
' this function will concatenate a range of cells and return one string
' useful when you have a rather large range of cells that you need to add up
Dim retVal, dlm As String
retVal = ""
If delim = Null Then
dlm = ""
Else
dlm = delim
End If
For Each cell In useThis
if cstr(cell.value)<>"" and cstr(cell.value)<>" " then
retVal = retVal & cstr(cell.Value) & dlm
end if
Next
If dlm <> "" Then
retVal = Left(retVal, Len(retVal) - Len(dlm))
End If
concat = retVal
End Function
Using source or $0 will not give you the real path of your script. You could use the process id of the script to retrieve its real path
ls -l /proc/$$/fd |
grep "255 ->" |
sed -e 's/^.\+-> //'
I am using this script and it has always served me well :)
Easiest way:
byte[] buffer;
using (Stream stream = new IO.FileStream("file.pdf"))
{
buffer = new byte[stream.Length - 1];
stream.Read(buffer, 0, buffer.Length);
}
using (Stream stream = new IO.FileStream("newFile.pdf"))
{
stream.Write(buffer, 0, buffer.Length);
}
Or something along these lines...
i just place one image in " d drive-->Data-->IMG". The image name is x.jpg
:
And on c# code type
ImageBrush myBrush = new ImageBrush();
myBrush.ImageSource = new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), "D:\\Data\\IMG\\x.jpg"));
(please put double slash in between path)
this.Background = myBrush;
finally i got the background..

The innerHtml is a property of HTML-Elements, which allows you to set it’s html-content programatically. There is also a innerText property which defines the content as plain text.
The [attributeName]="value"
box bracket , surrounding the attribute defines an Angular input-binding. That means, that the value of the property (in your case innerHtml) is bound to the given expression, when the expression-result changes, the property value changes too.
So basically [innerHtml]
allows you to bind and dynamically change the html-conent of the given HTML-Element.
select right(rtrim('94342KMR'),3)
This will fetch the last 3 right string.
select substring(rtrim('94342KMR'),1,len('94342KMR')-3)
This will fetch the remaining Characters.
Class.forName() gives you the class object, which is useful for reflection. The methods that this object has are defined by Java, not by the programmer writing the class. They are the same for every class. Calling newInstance() on that gives you an instance of that class (i.e. calling Class.forName("ExampleClass").newInstance()
it is equivalent to calling new ExampleClass()
), on which you can call the methods that the class defines, access the visible fields etc.
In SQL, anything you evaluate / compute with NULL
results into UNKNOWN
This is why SELECT * FROM MyTable WHERE MyColumn != NULL
or SELECT * FROM MyTable WHERE MyColumn <> NULL
gives you 0 results.
To provide a check for NULL
values, isNull function is provided.
Moreover, you can use the IS
operator as you used in the third query.
Hope this helps.
PermGen space is replaced by MetaSpace in Java 8. The PermSize and MaxPermSize JVM arguments are ignored and a warning is issued if present at start-up.
Most allocations for the class metadata are now allocated out of native memory. * The classes that were used to describe class metadata have been removed.
Main difference between old PermGen and new MetaSpace is, you don't have to mandatory define upper limit of memory usage. You can keep MetaSpace space limit unbounded. Thus when memory usage increases you will not get OutOfMemoryError error. Instead the reserved native memory is increased to full-fill the increase memory usage.
You can define the max limit of space for MetaSpace, and then it will throw OutOfMemoryError : Metadata space. Thus it is important to define this limit cautiously, so that we can avoid memory waste.
As Ben said, you are POSTing your request ( HttpMethod.Post specified in your code )
The querystring (get) parameters included in your url probably will not do anything.
Try this:
string url = "http://myserver/method";
string content = "param1=1¶m2=2";
HttpClientHandler handler = new HttpClientHandler();
HttpClient httpClient = new HttpClient(handler);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
HttpResponseMessage response = await httpClient.SendAsync(request,content);

With Android O the behaviour of the ANDROID_ID will change. The ANDROID_ID will be different per app per user on the phone.
Taken from: https://android-developers.googleblog.com/2017/04/changes-to-device-identifiers-in.html
Android ID
In O, Android ID (Settings.Secure.ANDROID_ID or SSAID) has a different value for each app and each user on the device. Developers requiring a device-scoped identifier, should instead use a resettable identifier, such as Advertising ID, giving users more control. Advertising ID also provides a user-facing setting to limit ad tracking.
Additionally in Android O:
You can try my suggestion for a work around in Doug's approach.
But if you want to stick with your logic though, you can try this:
Option Explicit
Sub GetUnique()
Dim rng As Range
Dim myarray, myunique
Dim i As Integer
ReDim myunique(1)
With ThisWorkbook.Sheets("Sheet1")
Set rng = .Range(.Range("A1"), .Range("A" & .Rows.Count).End(xlUp))
myarray = Application.Transpose(rng)
For i = LBound(myarray) To UBound(myarray)
If IsError(Application.Match(myarray(i), myunique, 0)) Then
myunique(UBound(myunique)) = myarray(i)
ReDim Preserve myunique(UBound(myunique) + 1)
End If
Next

This uses array instead of range.
It also uses Match
function instead of a nested For Loop
.
I didn't have the time to check the time difference though.
So I leave the testing to you.
int lastInt = integerList[integerList.Count-1];
<h1 style="text-align: left; float: left;">Text 1</h1>
<h2 style="text-align: right; float: right; display: inline;">Text 2</h2>
<hr style="clear: both;" />
Hope this helps!
You can do this with .htaccess:

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName
to be the name of the file you wish to open.
Private Const TargetWBName As String = "myworkbook.xlsx"
'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
WorkbookOpen = False
On Error GoTo WorkBookNotOpen
If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
WorkbookOpen = True
Exit Function
End If
WorkBookNotOpen:
End Function
Private Sub Workbook_Open()
'Check if our target workbook is open
If WorkbookOpen(TargetWBName) = False Then
'set calculation to manual
Application.Calculation = xlCalculationManual
Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
DoEvents
Me.Close False
End If
End Sub
Set the constant 'TargetWBName' to be the name of the workbook that you wish to open.
This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself.
*NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True
after Me.Close
A lot of people come to this page with the goal of finding the webpack config and files in order to add their own configuration to them. Another way to achieve this without running npm run eject
is to use react-app-rewired. This allows you to overwrite your webpack config file without ejecting.
It's also worth noting that ActiveX controls only work in Windows, whereas Form Controls will work on both Windows and MacOS versions of Excel.
Also i'd like to add that if one's trying to apply shadow in a TouchableHighlight Component in which child has borderRadius, the parent element (TouchableHighlight) also need the radius set in order to elevation prop work on Android.
There's an Abstract Class Dictionary
http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html
However this requires implementation.
Java gives us a nice implementation called a Hashtable

The question does not make clear what exactly you want to achieve.
List has the append
method, which appends its argument to the list:
>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.append(list_two)
>>> list_one
[1, 2, 3, [4, 5, 6]]
There's also the extend
method, which appends items from the list you pass as an argument:
>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.extend(list_two)
>>> list_one
[1, 2, 3, 4, 5, 6]
And of course, there's the insert
method which acts similarly to append
but allows you to specify the insertion point:
>>> list_one.insert(2, list_two)
>>> list_one
[1, 2, [4, 5, 6], 3, 4, 5, 6]
To extend a list at a specific insertion point you can use list slicing (thanks, @florisla):
>>> l = [1, 2, 3, 4, 5]
>>> l[2:2] = ['a', 'b', 'c']
>>> l
[1, 2, 'a', 'b', 'c', 3, 4, 5]
List slicing is quite flexible as it allows to replace a range of entries in a list with a range of entries from another list:
>>> l = [1, 2, 3, 4, 5]
>>> l[2:4] = ['a', 'b', 'c'][1:3]
>>> l
[1, 2, 'b', 'c', 5]
What even is ‘children’?
The React docs say that you can use
props.children
on components that represent ‘generic boxes’ and that don’t know their children ahead of time. For me, that didn’t really clear things up. I’m sure for some, that definition makes perfect sense but it didn’t for me.My simple explanation of what
this.props.children
does is that it is used to display whatever you include between the opening and closing tags when invoking a component.A simple example:
Here’s an example of a stateless function that is used to create a component. Again, since this is a function, there is no
this
keyword so just useprops.children
const Picture = (props) => {
return (
<div>
<img src={props.src}/>
{props.children}
</div>
)
}
This component contains an
<img>
that is receiving someprops
and then it is displaying{props.children}
.Whenever this component is invoked
{props.children}
will also be displayed and this is just a reference to what is between the opening and closing tags of the component.
//App.js
render () {
return (
<div className='container'>
<Picture key={picture.id} src={picture.src}>
//what is placed here is passed as props.children
</Picture>
</div>
)
}
Instead of invoking the component with a self-closing tag
<Picture />
if you invoke it will full opening and closing tags<Picture> </Picture>
you can then place more code between it.This de-couples the
<Picture>
component from its content and makes it more reusable.
Reference: A quick intro to React’s props.children
fill_parent
(deprecated) = match_parent
The border of the child view expands to match the border of the parent view.
wrap_content
The border of the child view wraps snugly around its own content.
Here are some images to make things more clear. The green and red are TextViews
. The white is a LinearLayout
showing through.
Every View
(a TextView
, an ImageView
, a Button
, etc.) needs to set the width
and the height
of the view. In the xml layout file, that might look like this:
android:layout_width="wrap_content"
android:layout_height="match_parent"
Besides setting the width and height to match_parent
or wrap_content
, you could also set them to some absolute value:
android:layout_width="100dp"
android:layout_height="200dp"
Generally that is not as good, though, because it is not as flexible for different sized devices. After you have understood wrap_content
and match_parent
, the next thing to learn is layout_weight
.

The explanation in this answer assumes there is no margin or padding. But even if there is, the basic concept is still the same. The view border/spacing is just adjusted by the value of the margin or padding.
why not just use a button instead of submit. clicking the button will let you construct a proper url for your browser to redirect to.
$("#button").click(function() {
var url = 'site.com/process.php?';
$('form input').each(function() {
url += 'key=' + $(this).val() + "&";
});
// handle removal of last &.
window.location.replace(url);
});
Many correct answers have been given here, but I'm adding this one to emphasize one point which caused some rushed attempts to fail before: exclude-dir
takes a pattern, not a path to a directory.
Say your search is:
grep -r myobject
And you notice that your output is cluttered with results from the src/other/objects-folder
. This command will not give you the intended result:
grep -r myobject --exclude-dir=src/other/objects-folder
And you may wonder why exclude-dir
isn't working! To actually exclude results from the objects-folder
, simply do this:
grep -r myobject --exclude-dir=objects-folder
In other words, just use the folder name, not the path. Obvious once you know it.
From the man page:
--exclude-dir=GLOB
Skip any command-line directory with a name suffix that matches the pattern GLOB. When searching recursively, skip any subdirectory whose base name matches GLOB. Ignore any redundant trailing slashes in GLOB.
The answer is weaved amongst the various posts here, I'll so my best, but it looks like a really simple and obvious reason.
1) is that there usually is a "user" variable in the udev rule some thing like USER="your_user" probably right after the GROUP="plugdev"
2) You need to use the correct SYSFS{idVendor}==”####" and SYSFS{idProduct}=="####" values for your device/s. If you have devices from more than one manufacture, say like one from Samsung and one from HTC, then you need to have an entry(rule) for each vendor, not an entry for each device but for each different vendor you will use, so you need an entry for HTC and Samsung. It looks like you have your entry for Samsung now you need another. Remember the USER="your_user". Use 'lsusb' like Robert Seimer suggests to find the idVendor and idProduct, they are usually some numbers and letters in this format X#X#:#X#X I think the first one is the idVendor and the second idProduct but your going to need to do this for each brand of phone/tablet you have.
3) I havent figured out how 51-adb.rules and 99-adb.rules are different or why.
4) maybe try adding "plugdev" group to your user with "usermod -a -G plugdev your_user", Try that at your own risk, though I don't thinks it anyriskier than launching a gui as root but I believe if necessary you should at least use "gksudo eclipse" instead.
I hope that helped clearify some things, the udev rules syntax is a bit of a mystery to me aswell, but from what I hear it can be different for different systems so try some things out, one ate a time, and note what change works.
Prior to PHP 5.4:
$myArray = array();

$myArray = [];
You can use angular2 directives. Plunkr
import { Directive, ElementRef, HostListener, Input } from '@angular/core';
@Directive({
selector: '[OnlyNumber]'
})
export class OnlyNumber {
constructor(private el: ElementRef) { }
@Input() OnlyNumber: boolean;
@HostListener('keydown', ['$event']) onKeyDown(event) {
let e = <KeyboardEvent> event;
if (this.OnlyNumber) {
if ([46, 8, 9, 27, 13, 110, 190].indexOf(e.keyCode) !== -1 ||
// Allow: Ctrl+A
(e.keyCode === 65 && (e.ctrlKey || e.metaKey)) ||
// Allow: Ctrl+C
(e.keyCode === 67 && (e.ctrlKey || e.metaKey)) ||
// Allow: Ctrl+V
(e.keyCode === 86 && (e.ctrlKey || e.metaKey)) ||
// Allow: Ctrl+X
(e.keyCode === 88 && (e.ctrlKey || e.metaKey)) ||
// Allow: home, end, left, right
(e.keyCode >= 35 && e.keyCode <= 39)) {
// let it happen, don't do anything
return;
}
// Ensure that it is a number and stop the keypress
if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
e.preventDefault();
}
}
}
}
and you need to write the directive name in your input as an attribute
<input OnlyNumber="true" />
don't forget to write your directive in declarations array of your module.
By using regex you would still need functional keys
export class OnlyNumber {
regexStr = '^[0-9]*$';
constructor(private el: ElementRef) { }
@Input() OnlyNumber: boolean;
@HostListener('keydown', ['$event']) onKeyDown(event) {
let e = <KeyboardEvent> event;
if (this.OnlyNumber) {
if ([46, 8, 9, 27, 13, 110, 190].indexOf(e.keyCode) !== -1 ||
// Allow: Ctrl+A
(e.keyCode == 65 && e.ctrlKey === true) ||
// Allow: Ctrl+C
(e.keyCode == 67 && e.ctrlKey === true) ||
// Allow: Ctrl+V
(e.keyCode == 86 && e.ctrlKey === true) ||
// Allow: Ctrl+X
(e.keyCode == 88 && e.ctrlKey === true) ||
// Allow: home, end, left, right
(e.keyCode >= 35 && e.keyCode <= 39)) {
// let it happen, don't do anything
return;
}
let ch = String.fromCharCode(e.keyCode);
let regEx = new RegExp(this.regexStr);
if(regEx.test(ch))
return;
else
e.preventDefault();
}
}
}
CharSequence is an interface and String is its one of the implementations other than StringBuilder, StringBuffer and many other.
So, just as you use InterfaceName i = new ItsImplementation()
, you can use CharSequence cs = new String("string")
or simply CharSequence cs = "string";
Foreach loop:
- Iterations takes place sequentially, one by one
- foreach loop is run from a single Thread.
- foreach loop is defined in every framework of .NET
- Execution of slow processes can be slower, as they're run serially
- Process 2 can't start until 1 is done. Process 3 can't start until 2 & 1 are done...
- Execution of quick processes can be faster, as there is no threading overhead
Parallel.ForEach:
- Execution takes place in parallel way.
- Parallel.ForEach uses multiple Threads.
- Parallel.ForEach is defined in .Net 4.0 and above frameworks.
- Execution of slow processes can be faster, as they can be run in parallel
- Processes 1, 2, & 3 may run concurrently (see reused threads in example, below)
- Execution of quick processes can be slower, because of additional threading overhead
The following example clearly demonstrates the difference between traditional foreach loop and
Parallel.ForEach() Example
using System;
using System.Diagnostics;
using System.Threading;
using System.Threading.Tasks;
namespace ParallelForEachExample
{
class Program
{
static void Main()
{
string[] colors = {
"1. Red",
"2. Green",
"3. Blue",
"4. Yellow",
"5. White",
"6. Black",
"7. Violet",
"8. Brown",
"9. Orange",
"10. Pink"
};
Console.WriteLine("Traditional foreach loop\n");
//start the stopwatch for "for" loop
var sw = Stopwatch.StartNew();
foreach (string color in colors)
{
Console.WriteLine("{0}, Thread Id= {1}", color, Thread.CurrentThread.ManagedThreadId);
Thread.Sleep(10);
}
Console.WriteLine("foreach loop execution time = {0} seconds\n", sw.Elapsed.TotalSeconds);
Console.WriteLine("Using Parallel.ForEach");
//start the stopwatch for "Parallel.ForEach"
sw = Stopwatch.StartNew();
Parallel.ForEach(colors, color =>
{
Console.WriteLine("{0}, Thread Id= {1}", color, Thread.CurrentThread.ManagedThreadId);
Thread.Sleep(10);
}
);
Console.WriteLine("Parallel.ForEach() execution time = {0} seconds", sw.Elapsed.TotalSeconds);
Console.Read();
}
}
}
Output
Traditional foreach loop
1. Red, Thread Id= 10
2. Green, Thread Id= 10
3. Blue, Thread Id= 10
4. Yellow, Thread Id= 10
5. White, Thread Id= 10
6. Black, Thread Id= 10
7. Violet, Thread Id= 10
8. Brown, Thread Id= 10
9. Orange, Thread Id= 10
10. Pink, Thread Id= 10
foreach loop execution time = 0.1054376 seconds
Using Parallel.ForEach example
1. Red, Thread Id= 10
3. Blue, Thread Id= 11
4. Yellow, Thread Id= 11
2. Green, Thread Id= 10
5. White, Thread Id= 12
7. Violet, Thread Id= 14
9. Orange, Thread Id= 13
6. Black, Thread Id= 11
8. Brown, Thread Id= 10
10. Pink, Thread Id= 12
Parallel.ForEach() execution time = 0.055976 seconds
An easy and usable way to solve this problem
getGetSuppor(filter): Observale<any[]> {

private toQueryString(query): string {
var parts = [];
for (var property in query) {

If your close button is going to be text, this works very well for me:
#close {
position: fixed;
width: 70%; /* the width of the parent */
text-align: right;
}
#close span {
cursor: pointer;
}
Then your HTML
can just be:
<div id="close"><span id="x">X</span></div>
I just came across this question and thought on contributing with a solution that does not use regex.
In my case I use a helper method:
public boolean notNumber(String input){
boolean notNumber = false;
try {
// must not start with a number
@SuppressWarnings("unused")
double checker = Double.valueOf(input.substring(0,1));
}
catch (Exception e) {
notNumber = true;
}
return notNumber;
}
Probably an overkill, but I try to avoid regex whenever I can.
To revert a migration:
python manage.py migrate <APP_NAME> <MIGRATION_NUMBER_PREFIX>
MIGRATION_NUMBER_PREFIX
is the number prefix of the migration you want to revert to, for instance 0001
to go to 0001_initial.py
migration. then you can delete that migration.
You can use
zero
as your migration number to revert all migrations of an app.
Here is an example how to make C code completly unaware about what is actually used of HW for running the app. The main.c does the setup and then the free layer can be implemented on any compiler/arch. I think it is quite neat for abstracting C code a bit, so it does not get to be to spesific.
Adding a complete compilable example here.
/* free.h */
#ifndef _FREE_H_
#define _FREE_H_
#include <stdio.h>
#include <string.h>
typedef unsigned char ubyte;
typedef void (*F_ParameterlessFunction)() ;
typedef void (*F_CommandFunction)(ubyte byte) ;
void F_SetupLowerLayer (
F_ParameterlessFunction initRequest,
F_CommandFunction sending_command,
F_CommandFunction *receiving_command);
#endif
/* free.c */
static F_ParameterlessFunction Init_Lower_Layer = NULL;
static F_CommandFunction Send_Command = NULL;
static ubyte init = 0;
void recieve_value(ubyte my_input)
{
if(init == 0)
{
Init_Lower_Layer();
init = 1;
}
printf("Receiving 0x%02x\n",my_input);
Send_Command(++my_input);
}
void F_SetupLowerLayer (
F_ParameterlessFunction initRequest,
F_CommandFunction sending_command,
F_CommandFunction *receiving_command)
{
Init_Lower_Layer = initRequest;
Send_Command = sending_command;
*receiving_command = &recieve_value;
}
/* main.c */
int my_hw_do_init()
{
printf("Doing HW init\n");
return 0;
}
int my_hw_do_sending(ubyte send_this)
{
printf("doing HW sending 0x%02x\n",send_this);
return 0;
}
F_CommandFunction my_hw_send_to_read = NULL;
int main (void)
{
ubyte rx = 0x40;
F_SetupLowerLayer(my_hw_do_init,my_hw_do_sending,&my_hw_send_to_read);
my_hw_send_to_read(rx);
getchar();
return 0;

You would have to watch the DOM node changes. There is an API called MutationObserver
, but it looks like the support for it is very limited. This SO answer has a link to the status of the API, but it seems like there is no support for it in IE or Opera so far.
One way you could get around this problem is to have the part of the code that modifies the data-select-content-val
attribute dispatch an event that you can listen to.
For example, see: http://jsbin.com/arucuc/3/edit on how to tie it together.
The code here is
$(function() {
// Here you register for the event and do whatever you need to do.
$(document).on('data-attribute-changed', function() {
var data = $('#contains-data').data('mydata');
alert('Data changed to: ' + data);
});
$('#button').click(function() {
$('#contains-data').data('mydata', 'foo');
// Whenever you change the attribute you will user the .trigger
// method. The name of the event is arbitrary
$(document).trigger('data-attribute-changed');
});
$('#getbutton').click(function() {
var data = $('#contains-data').data('mydata');
alert('Data is: ' + data);
});
});
You can analyze the core dump file using the "gdb" command.
gdb - The GNU Debugger
syntax:
# gdb executable-file core-file
example: # gdb out.txt core.xxx
if this is a windows box, the simplest thing to do is to stop the servers, add skip-grant-tables to the mysql configuration file, and restart the server.
once you've fixed your permission problems, repeat the above but remove the skip-grant-tables option.
if you don't know where your configuration file is, then log in to mysql send SHOW VARIABLES LIKE '%config%'
and one of the rows returned will tell you where your configuration file is.
Set the Screen orientation to portrait in Manifest file under the activity Tag.
Well, the selected answer is not the most correct one because it will fail outside UTC. Depending on the timezone (list) there could be time adjustments creating days "without" 24 hours, and this will make the calculation (60*60*24) fail.
Here it is an example of it:
date_default_timezone_set('europe/lisbon');
$time1 = strtotime('2016-03-27');
$time2 = strtotime('2016-03-29');
echo floor( ($time2-$time1) /(60*60*24));
^-- the output will be **1**
So the correct solution will be using DateTime
date_default_timezone_set('europe/lisbon');
$date1 = new DateTime("2016-03-27");
$date2 = new DateTime("2016-03-29");
echo $date2->diff($date1)->format("%a");
^-- the output will be **2**

With 'Enter' is better use ReadLine() or Read(2), because key 'Enter' generate 2 symbols. If user enter any text next Pause() also wil be skipped even with Read(2). So ReadLine() is better:
Sub Pause()
WScript.Echo ("Press Enter to continue")
z = WScript.StdIn.ReadLine()
End Sub

How to add 1 year to a date and then subtract 1 day from it in asp.net c#
Convert.ToDateTime(txtDate.Value.Trim()).AddYears(1).AddDays(-1);
i know thats a old question but make sure if you are working with references the proper supporting engine is defined. set innodb engine for both tables and same data type for the reference columns
$table->engine = 'InnoDB';
If you can't change the datatype on the table itself to use varchar(max), then change your query to this:
SELECT *
FROM [Village]
WHERE CONVERT(VARCHAR(MAX), [CastleType]) = 'foo'
If you try joining C on a field from B before joining B, i.e.:
SELECT A.x,
A.y,
A.z
FROM A
INNER JOIN C
on B.x = C.x
INNER JOIN B
on A.x = B.x
your query will fail, so in this case the order matters.

Sergey is correct, but if you need to get a response from your home-spun dialog(s) for evaluation in the same block of code that invoked it, you should use .showAndWait(), not .show(). Here's my rendition of a couple of the dialog types that are provided in Swing's OptionPane:
public class FXOptionPane {
public enum Response { NO, YES, CANCEL };
private static Response buttonSelected = Response.CANCEL;
private static ImageView icon = new ImageView();
static class Dialog extends Stage {
public Dialog( String title, Stage owner, Scene scene, String iconFile ) {
setTitle( title );
initStyle( StageStyle.UTILITY );
initModality( Modality.APPLICATION_MODAL );
initOwner( owner );
setResizable( false );
setScene( scene );
icon.setImage( new Image( getClass().getResourceAsStream( iconFile ) ) );
}
public void showDialog() {
sizeToScene();
centerOnScreen();
showAndWait();
}
}
static class Message extends Text {
public Message( String msg ) {
super( msg );
setWrappingWidth( 250 );
}
}
public static Response showConfirmDialog( Stage owner, String message, String title ) {
VBox vb = new VBox();
Scene scene = new Scene( vb );
final Dialog dial = new Dialog( title, owner, scene, "res/Confirm.png" );
vb.setPadding( new Inset(10,10,10,10) );
vb.setSpacing( 10 );
Button yesButton = new Button( "Yes" );
yesButton.setOnAction( new EventHandler<ActionEvent>() {
@Override public void handle( ActionEvent e ) {
dial.close();
buttonSelected = Response.YES;
}
} );
Button noButton = new Button( "No" );
noButton.setOnAction( new EventHandler<ActionEvent>() {
@Override public void handle( ActionEvent e ) {
dial.close();
buttonSelected = Response.NO;
}
} );
BorderPane bp = new BorderPane();
HBox buttons = new HBox();
buttons.setAlignment( Pos.CENTER );
buttons.setSpacing( 10 );
buttons.getChildren().addAll( yesButton, noButton );
bp.setCenter( buttons );
HBox msg = new HBox();
msg.setSpacing( 5 );
msg.getChildren().addAll( icon, new Message( message ) );
vb.getChildren().addAll( msg, bp );
dial.showDialog();
return buttonSelected;
}
public static void showMessageDialog( Stage owner, String message, String title ) {
showMessageDialog( owner, new Message( message ), title );
}
public static void showMessageDialog( Stage owner, Node message, String title ) {
VBox vb = new VBox();
Scene scene = new Scene( vb );
final Dialog dial = new Dialog( title, owner, scene, "res/Info.png" );
vb.setPadding( new Inset(10,10,10,10) );
vb.setSpacing( 10 );
Button okButton = new Button( "OK" );
okButton.setAlignment( Pos.CENTER );
okButton.setOnAction( new EventHandler<ActionEvent>() {
@Override public void handle( ActionEvent e ) {
dial.close();
}
} );
BorderPane bp = new BorderPane();
bp.setCenter( okButton );
HBox msg = new HBox();
msg.setSpacing( 5 );
msg.getChildren().addAll( icon, message );
vb.getChildren().addAll( msg, bp );
dial.showDialog();
}
}
If you want no index, read file using:
import pandas as pd
df = pd.read_csv('file.csv', index_col=0)
save it using
df.to_csv('file.csv', index=False)
In this way we can pass an array to a function, here this print function will print the contents of the array.
public class PassArrayToFunc {
public static void print(char [] arr) {
for(int i = 0 ; i<arr.length;i++) {
System.out.println(arr[i]);
}
}
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
char [] array = scan.next().toCharArray();
print(array);
scan.close();
}
}
public IList<Splitting> get(Guid companyId, long customrId) {
var res=from c in Customers_data_source
where c.CustomerId = customrId && c.CompanyID == companyId
from s in Splittings_data_srouce
where s.CustomerID = c.CustomerID
select s;
return res.ToList();
}
Check your project's properties. On the "Application" tab, select your Program
class as the Startup object:
Validation (HTML5): Attribute 'name' is not a valid attribute of element 'label'.
For now I just switched registry URL from https to http. Like this:
npm config set registry="http://registry.npmjs.org/"
As pointed in a reply already, the current answer is wrong, because the GROUP BY arbitrarily selects the record from the window.
If one is using MySQL 5.6, or MySQL 5.7 with ONLY_FULL_GROUP_BY
, the correct (deterministic) query is:
SELECT incomingEmails.*
FROM (
SELECT fromEmail, MAX(timestamp) `timestamp`
FROM incomingEmails
GROUP BY fromEmail
) filtered_incomingEmails
JOIN incomingEmails USING (fromEmail, timestamp)
GROUP BY fromEmail, timestamp
In order for the query to run efficiently, proper indexing is required.
Note that for simplification purposes, I've removed the LOWER()
, which in most cases, won't be used.
If you want to escape the data use
{{ $html }}
If don't want to escape the data use
{!! $html !!}
But till Laravel-4 you can use
{{ HTML::link('/auth/logout', 'Sign Out', array('class' => 'btn btn-default btn-flat')) }}
When comes to Laravel-5
{!! HTML::link('/auth/logout', 'Sign Out', array('class' => 'btn btn-default btn-flat')) !!}
You can also do this with the PHP function
{{ html_entity_decode($data) }}
go through the PHP document for the parameters of this function
And if you want to vary the speed and include callbacks simply add them like this :
jQuery.fn.extend({
slideRightShow: function(speed,callback) {
return this.each(function() {
$(this).show('slide', {direction: 'right'}, speed, callback);
});
},
slideLeftHide: function(speed,callback) {
return this.each(function() {
$(this).hide('slide', {direction: 'left'}, speed, callback);
});
},
slideRightHide: function(speed,callback) {
return this.each(function() {
$(this).hide('slide', {direction: 'right'}, speed, callback);
});
},
slideLeftShow: function(speed,callback) {
return this.each(function() {
$(this).show('slide', {direction: 'left'}, speed, callback);
});
}
});
CURDATE()
will give current date while NOW()
will give full date time.
Run the queries, and you will find out whats the difference between them.
SELECT NOW(); -- You will get 2010-12-09 17:10:18
SELECT CURDATE(); -- You will get 2010-12-09
This is extremely easy to do in Sass! Don't delve into JavaScript for this. The & selector in sass does exactly this.
http://thesassway.com/intermediate/referencing-parent-selectors-using-ampersand
The first thing I will try - determine if your code with alerts is actually rendered. I see some server "if" code in what you posted, so may be condition to render javascript is not satisfied. So, on the page you working on, right-click -> view source. Try to find the js code there. Please tell us if you found the code on the page.

, see below example!#selector(name)
.private
or public
doesn't matter; you can use private.override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)

let menuButton = UIBarButtonItem(image: menuButtonImage, style: .plain, target: self, action: #selector(didTapMenuButton))

ECMAScript 2021 brings Object.fromEntries
which does exactly the requirement:
const array = [ [ 'cardType', 'iDEBIT' ],
[ 'txnAmount', '17.64' ],
[ 'txnId', '20181' ],
[ 'txnType', 'Purchase' ],
[ 'txnDate', '2015/08/13 21:50:04' ],
[ 'respCode', '0' ],
[ 'isoCode', '0' ],
[ 'authCode', '' ],
[ 'acquirerInvoice', '0' ],
[ 'message', '' ],
[ 'isComplete', 'true' ],
[ 'isTimeout', 'false' ] ];
const obj = Object.fromEntries(array);
console.log(obj);
_x000D_
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/fromEntries
This will do it:
const array = [ [ 'cardType', 'iDEBIT' ],
[ 'txnAmount', '17.64' ],
[ 'txnId', '20181' ],
[ 'txnType', 'Purchase' ],
[ 'txnDate', '2015/08/13 21:50:04' ],
[ 'respCode', '0' ],
[ 'isoCode', '0' ],
[ 'authCode', '' ],
[ 'acquirerInvoice', '0' ],
[ 'message', '' ],
[ 'isComplete', 'true' ],
[ 'isTimeout', 'false' ] ];
var obj = {};
array.forEach(function(data){
obj[data[0]] = data[1]
});
console.log(obj);

place all files in one folder. place a .htaccess file in that folder and give it the value deny all. then in index.php thats placed outside of the folder have it echo out the right pages based on user input or event
You can use System.IO.Path.GetFileName
to do this.
E.g.,
string[] files = Directory.GetFiles(dir);
foreach(string file in files)
Console.WriteLine(Path.GetFileName(file));
While you could use FileInfo
, it is much more heavyweight than the approach you are already using (just retrieving file paths). So I would suggest you stick with GetFiles
unless you need the additional functionality of the FileInfo
class.
What are CN, OU, DC?
From RFC2253 (UTF-8 String Representation of Distinguished Names):
String X.500 AttributeType ------------------------------ CN commonName L localityName ST stateOrProvinceName O organizationName OU organizationalUnitName C countryName STREET streetAddress DC domainComponent UID userid
What does the string from that query mean?
The string ("CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
) is a path from an hierarchical structure (DIT = Directory Information Tree) and should be read from right (root) to left (leaf).
It is a DN (Distinguished Name) (a series of comma-separated key/value pairs used to identify entries uniquely in the directory hierarchy). The DN is actually the entry's fully qualified name.
Here you can see an example where I added some more possible entries.
The actual path is represented using green.
The following paths represent DNs (and their value depends on what you want to get after the query is run):
"DC=gp,DC=gl,DC=google,DC=com"
"OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
"OU=People,DC=gp,DC=gl,DC=google,DC=com"
"OU=Groups,DC=gp,DC=gl,DC=google,DC=com"
"CN=QA-Romania,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
"CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
"CN=Diana Anton,OU=People,DC=gp,DC=gl,DC=google,DC=com"
