keytool
comes with the JDK installation (in the bin
folder):
keytool -importcert -file "your.cer" -keystore your.jks -alias "<anything>"
This will create a new keystore and add just your certificate to it.
So, you can't convert a certificate to a keystore: you add a certificate to a keystore.
Great question.
It can be achieved via an extension:
I got this error because I declared a variable (above the ConfigureServices method) of type that was my context. I had:

Not sure what I was thinking. I know it's legal to do this if your passing in a parameter to the Configure method.
You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save
(or the before_validation
) callback. Here's an example of the relevant code for a model like yours:
class Place < ActiveRecord::Base before_save do |place| place.city = place.city.downcase.titleize place.country = place.country.downcase.titleize end end
You can also check out the Ruby on Rails guide for more info.
To answer you question more directly, something like this would work:
<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>
This just means if f.object.city
exists, display the titlecase
version of it, and if it doesn't display a blank string.
The body hasn't been defined at this point yet. In general, you want to create all elements before you execute javascript that uses these elements. In this case you have some javascript in the head
section that uses body
. Not cool.
You want to wrap this code in a window.onload
handler or place it after the <body>
tag (as mentioned by e-bacho 2.0).
<head>
<title>Javascript Tests</title>
<script type="text/javascript">
window.onload = function() {
var mySpan = document.createElement("span");
mySpan.innerHTML = "This is my span!";
mySpan.style.color = "red";
document.body.appendChild(mySpan);
alert("Why does the span change after this alert? Not before?");
}
</script>
</head>
Operator overloading is used in Java for the concatenation of the String type:
String concat = "one" + "two";
However, you cannot define your own operator overloads.
Depending on what sort of risks you will accept and how well you know and trust the data, you can use simplistic variable interpolation.
$: x="
this
is
variably indented
stuff
"
$: echo "$x" # preserves the newlines and spacing
this
is
variably indented
stuff
$: echo $x # no quotes, stacks it "neatly" with minimal spacing
this is variably indented stuff
Note that the search query is now case sensitive.
When using
SELECT * FROM table WHERE `first_name` LIKE '%$search_term%'
It will match both "Larry" and "larry". With this concat_ws, it will suddenly become case sensitive!
This can be fixed by using the following query:
SELECT * FROM table WHERE UPPER(CONCAT_WS(' ', `first_name`, `last_name`) LIKE UPPER('%$search_term%')
Edit: Note that this only works on non-binary elements. See also mynameispaulie's answer.
Commonly used in UIsegmentedControl, "error" appear when compiling in 64bits instead of 32bits, easy way for not pass it to a new variable is to use this tips, add (int):

instead of :
[_monChiffre setUnite:[_valUnites selectedSegmentIndex]];
<form action="javascript:completeAndRedirect();">

Changing action to point at your function would solve the problem, in a different way.
select max(Salary) from Employee
where Salary
not in (Select top4 salary from Employee);
because answer is as follows
max(5,6,7,8)
so 5th highest record will be displayed, first four will not be considered
Safari is blocking any call to window.open() which is made inside an async call.
The solution that I found to this problem is to call window.open before making an asnyc call and set the location when the promise resolves.
var windowReference = window.open();
myService.getUrl().then(function(url) {
windowReference.location = url;
});
As APC rightly pointed out, your start_date column appears to be a TIMESTAMP but it could be a TIMESTAMP WITH LOCAL TIMEZONE or TIMESTAMP WITH TIMEZONE datatype too. These could well influence any queries you were doing on the data if your database server was in a different timezone to yourself. However, let's keep this simple and assume you are in the same timezone as your server. First, to give you the confidence, check that the start_date is a TIMESTAMP data type.
Use the SQLPlus DESCRIBE command (or the equivalent in your IDE) to verify this column is a TIMESTAMP data type.
eg
DESCRIBE mytable
Should report :
Name Null? Type
----------- ----- ------------
NAME VARHAR2(20)
START_DATE TIMESTAMP
If it is reported as a Type = TIMESTAMP then you can query your date ranges with simplest TO_TIMESTAMP date conversion, one which requires no argument (or picture).
We use TO_TIMESTAMP to ensure that any index on the START_DATE column is considered by the optimizer. APC's answer also noted that a function based index could have been created on this column and that would influence the SQL predicate but we cannot comment on that in this query. If you want to know how to find out what indexes have been applied to table, post another question and we can answer that separately.
So, assuming there is an index on start_date, which is a TIMESTAMP datatype and you want the optimizer to consider it, your SQL would be :
select * from mytable where start_date between to_timestamp('15-JAN-10') AND to_timestamp('17-JAN-10')+.9999999
+.999999999 is very close to but isn't quite 1 so the conversion of 17-JAN-10 will be as close to midnight on that day as possible, therefore you query returns both rows.
The database will see the BETWEEN as from 15-JAN-10 00:00:00:0000000 to 17-JAN-10 23:59:59:99999 and will therefore include all dates from 15th,16th and 17th Jan 2010 whatever the time component of the timestamp.
Hope that helps.

If you get an error saying "Cannot Bulk load file because you don't have access right"
First make sure the path and file name you have given are correct.
then try giving the bulkadmin role to the user. To do so follow the steps :- In Object Explorer -> Security -> Logins -> Select the user (right click) -> Properties -> Server Roles -> check the bulkadmin checkbox -> OK.
This worked for me.
You don't have any example code but I assume you want to do something like this?
@View({
directives: [NgClass],
styles: [`
.${TodoModel.COMPLETED} {
text-decoration: line-through;
}
.${TodoModel.STARTED} {
color: green;
}
`],
template: `<div>
<span [ng-class]="todo.status" >{{todo.title}}</span>
<button (click)="todo.toggle()" >Toggle status</button>
</div>`
})
You assign ng-class
to a variable which is dynamic (a property of a model called TodoModel
as you can guess).
todo.toggle()
is changing the value of todo.status
and there for the class of the input is changing.
This is an example for class name but actually you could do the same think for css properties.
I hope this is what you meant.
This example is taken for the great egghead tutorial here.
I'm not sure, but i believe the speed of one or the other changes depending on the programming language you're using.
I usually prefer to use switch. That way the code is simplear to read.
As other users have mentioned, enumerate
is a generator that adds an incremental index next to each item of an iterable.
So if you have a list say l = ["test_1", "test_2", "test_3"]
, the list(enumerate(l))
will give you something like this: [(0, 'test_1'), (1, 'test_2'), (2, 'test_3')]
.
Now, when this is useful? A possible use case is when you want to iterate over items, and you want to skip a specific item that you only know its index in the list but not its value (because its value is not known at the time).
for index, value in enumerate(joint_values):
if index == 3:
continue
# Do something with the other `value`
So your code reads better because you could also do a regular for loop with range
but then to access the items you need to index them (i.e., joint_values[i]
).
Although another user mentioned an implementation of enumerate
using zip
, I think a more pure (but slightly more complex) way without using itertools
is the following:
def enumerate(l, start=0):
return zip(range(start, len(l) + start), l)
Example:
l = ["test_1", "test_2", "test_3"]
enumerate(l)
enumerate(l, 10)
Output:
[(0, 'test_1'), (1, 'test_2'), (2, 'test_3')]
[(10, 'test_1'), (11, 'test_2'), (12, 'test_3')]
As mentioned in the comments, this approach with range will not work with arbitrary iterables as the original enumerate
function does.
Use character classes. A character class beginning with caret will match anything not in the class.

I simply added 5 "SPACE"s between clone
and the url

I think this thread may be helpful: http://forums.macosxhints.com/archive/index.php/t-70973.html
To paraphrase, you can rename it with the .command extension or create an AppleScript to run the shell.
With typescript we can leverage type aliases, like so:
type KeyboardEvent = {
target: HTMLInputElement,
key: string,
};
const onKeyPress = (e: KeyboardEvent) => {
if ('Enter' === e.key) { // Enter keyboard was pressed!
submit(e.target.value);
e.target.value = '';
return;
}
// continue handle onKeyPress input events...
};
A surprisingly fast approach is to use set
:
a = ['a', 'b', 'c']
str = "a123"
if set(a) & set(str):
print("some of the strings found in str")
else:
print("no strings found in str")
This works if a
does not contain any multiple-character values (in which case use any
as listed above). If so, it's simpler to specify a
as a string: a = 'abc'
.
One possibility is to delete to cookie you are looking for the expiration date from and rewrite it. Then you'll know the expiration date.

You can use for loop to untar multiple .tar.gz files to another folder. The following code will take /destination/folder/path as an argument to the script and untar all .tar.gz files present at the current location in /destination/folder/path.
if [ $# -ne 1 ];
then
echo "invalid argument/s"
echo "Usage: ./script-file-name.sh /target/directory"
exit 0

for file in *.tar.gz
do
tar -zxvf "$file" --directory $1
done

There is a ToUnixTimeMilliseconds for DateTimeOffset in System
You can write similar method for DateTime:
public static long ToUnixTimeSeconds(this DateTime value)
{
return value.Ticks / 10000000L - 62135596800L;
}
10000000L - converting ticks to seconds
62135596800L - converting 01.01.01 to 01.01.1978

UPDATE 2019: As other answers are bit outdated, I'll add updated one here. In latest version there's no need to map the chrome folder to filesystem.
So, suppose I have a web folder containing HTML,CSS,JS files in desktop which i want to be updated when I make changes in chrome:=
1) You'd need a running local server like node etc, alternatively this vscode extension creates the server for you: live server VSCode extension, install it, run the server.
2) load the html page in chrome from running local server.
3) Open devTools->Sources->Filesystem->Add folder to workspace
4) Add the folder which is used in running local server. No additional mapping is required in latest chrome! Ta-da!
More on it Edit Files With Workspaces
Note that the changes made on the styles tab will NOT reflect on the filesystem files.
Instead you need to go to devtools->source->your_folder and then make your changes there and reload the page to see the effect.

You'll need the cookie plugin, which provides several additional signatures to the cookie function.
$.cookie('cookie_name', 'cookie_value')
stores a transient cookie (only exists within this session's scope, while $.cookie('cookie_name', 'cookie_value', 'cookie_expiration")
creates a cookie that will last across sessions - see http://www.stilbuero.de/2006/09/17/cookie-plugin-for-jquery/ for more information on the JQuery cookie plugin.
If you want to set cookies that are used for the entire site, you'll need to use JavaScript like this:
document.cookie = "name=value; expires=date; domain=domain; path=path; secure"
There are the slideDown, slideUp, and slideToggle functions native to jquery 1.3+, and they work quite nicely...
https://api.jquery.com/category/effects/
You can use slideDown just like this:
$("test").slideDown("slow");
And if you want to combine effects and really go nuts I'd take a look at the animate function which allows you to specify a number of CSS properties to shape tween or morph into. Pretty fancy stuff, that.
No you cannot. The only thing you can do is to insert content. Like so:
p:after {
content: "yo";
}
If you don't want to build your server side, like only developing on a client side (web app or a mobile app) , you could choose an Implicit Authentication .
As the document saying , first make a https request with
Fill in your CLIENT-ID and REDIRECT-URL you designated.
Then that's going to the log in page , but the most important thing is how to get the access token after the user correctly logging in.
After the user click the log in button with both correct account and password, the web page will redirect to the url you designated followed by a new access token.
I'm not familiar with javascript , but in Android studio , that's an easy way to add a listener which listen to the event the web page override the url to the new url (redirect event) , then it will pass the redirect url string to you , so you can easily split it to get the access-token like:
String access_token = url.split("=")[1];
Means to break the url into the string array in each "=" character , then the access token obviously exists at [1].
I found this in some other answer but eventually worked for me when I added the two answers.

If every input asks the same question, you should use a for
loop and an array of inputs:
Scanner dd = new Scanner(System.in);
int[] vars = new int[3];
for(int i = 0; i < vars.length; i++) {
System.out.println("Enter next var: ");
vars[i] = dd.nextInt();
}
Or as Chip suggested, you can parse the input from one line:
Scanner in = new Scanner(System.in);
int[] vars = new int[3];
System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
vars[i] = in.nextInt();
You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

if (httpWorkerRequestField != null)

var knownRequestHeadersField = httpWorkerRequest.GetType().GetField("_knownRequestHeaders", BindingFlags.Instance | BindingFlags.NonPublic);
if (knownRequestHeadersField != null)

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.
Here's how to do it for Internet Explorer:
function copy (str)
{
//for IE ONLY!
window.clipboardData.setData('Text',str);
}
I received the error Domain=NSURLErrorDomain Code=-1011 when using Parse, and providing the wrong clientKey. As soon as I corrected that, it began working.
My approach:
define a default constraint on the ModDate
column with a value of GETDATE()
- this handles the INSERT
case
have a AFTER UPDATE
trigger to update the ModDate
column
Something like:
CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
UPDATE dbo.TimeEntry
SET ModDate = GETDATE()
WHERE ID IN (SELECT DISTINCT ID FROM Inserted)
Here is another answer using Spring MVC's standaloneSetup. Using this way you can either autowire the controller class or Mock it.

}
@Test
public void contextLoads() {

}
This error is caused because your charset is wrong.
Set charset after open tag:
header('Content-Type: text/html; charset=utf-8');
And set charset utf8 in your database :
mysql_query("SET NAMES 'utf8'");
Other way is using of built-in method start timer & event TimerEvent.
Header:

I tore my hair out over this one too. Your code only works if the user has granted an extended permission for that which is not ideal.
In a nutshell, if you turn on the OAuth 2.0
for Canvas advanced option, Facebook will send a $_REQUEST['signed_request']
along with every page requested within your tab app. If you parse that signed_request you can get some info about the user including if they've liked the page or not.
function parsePageSignedRequest() {
if (isset($_REQUEST['signed_request'])) {
$encoded_sig = null;
$payload = null;
list($encoded_sig, $payload) = explode('.', $_REQUEST['signed_request'], 2);
$sig = base64_decode(strtr($encoded_sig, '-_', '+/'));
$data = json_decode(base64_decode(strtr($payload, '-_', '+/'), true));
return $data;
}
return false;
}
if($signed_request = parsePageSignedRequest()) {
if($signed_request->page->liked) {
echo "This content is for Fans only!";
} else {
echo "Please click on the Like button to view this tab!";
}
}
You can create a delay using the following example
setInterval(function(){alert("Hello")},3000);
Replace 3000 with # of milliseconds
You can place the content of what you want executed inside the function.
For Skin remove No Skin and add some skin into it
Usually we have the need to control the width of the dropdown menu; specially that's essential when the dropdown menu holds a form, e.g. login form --- then the dropdown menu and its items should be wide enough for ease of inputing username/email and password.
Besides, when the screen is smaller than 768px or when the window (containing the dropdown menu) is zoomed down to smaller than 768px, Bootstrap 3 responsively scales the dropdown menu to the whole width of the screen/window. We need to keep this reponsive action.
Hence, the following css class could do that:
@media (min-width: 768px) {
.dropdown-menu {
width: 300px !important; /* change the number to whatever that you need */
}
}
(I had used it in my web app.)

Ok, it seems that some versions of PHP have a limitation of length of GET params:
Please note that PHP setups with the suhosin patch installed will have a default limit of 512 characters for get parameters. Although bad practice, most browsers (including IE) supports URLs up to around 2000 characters, while Apache has a default of 8000.
To add support for long parameters with suhosin, add
suhosin.get.max_value_length = <limit>

There are some free tools that make these kind of search, for example, this one works fine and source code is available: https://sites.google.com/site/freejansoft/dbsearch
You'll need the Oracle ODBC driver and a DSN to use this tool.
As a refinement of simplest solution, and if you can’t or don’t want to install Powershell, just run:
dir /s /b | sort /r /+261 > out.txt
or (faster):
dir /s /b | sort /r /+261 /o out.txt
And lines longer than 260 will get to the top of listing. Note that you must add 1 to SORT column parameter (/+n).
var people =
[{"name": 'a75',"item1": "false","item2":"false"},
{"name": 'z32',"item1": "true","item2": "false"},
{"name": 'e77',"item1": "false","item2": "false"}];
function mycomparator(a,b) { return parseInt(a.name) - parseInt(b.name); }
people.sort(mycomparator);
something along the lines of this maybe (or as we used to say, this should work).
Something like this might help:
SET Today=%Date:~10,4%%Date:~4,2%%Date:~7,2%
mkdir C:\Test\Backup-%Today%
move C:\Test\Log\*.* C:\Test\Backup-%Today%\
SET Today=
The important part is the first line. It takes the output of the internal DATE
value and parses it into an environmental variable named Today
, in the format CCYYMMDD
, as in '20110407`.
The %Date:~10,4%
says to extract a *substring of the Date
environmental variable 'Thu 04/07/2011' (built in - type echo %Date%
at a command prompt) starting at position 10 for 4 characters (2011
). It then concatenates another substring of Date:
starting at position 4 for 2 chars (04
), and then concats two additional characters starting at position 7 (07
).
*The substring value starting points are 0-based.
You may need to adjust these values depending on the date format in your locale, but this should give you a starting point.
If EditText Field is been covered by the KeyBoard Use the following code:
EditText= findViewById(R.id.edittext)
EditText?.getParent()?.requestChildFocus(EditText,EditText)
If you want the Cursor to be in the Focused EditText than use EditText.requestFocus()
after the EditText?.getParent()?.requestChildFocus(EditText,EditText)
which helps to get the focus and Cursor in the Focused EditText.
It is a bad idea to select * from anything, period. This is why SSMS adds every field name, even if there are hundreds, instead of select *. It is extremely inefficient regardless of how large the table is. If you don't know what the fields are, its still more efficient to pull them out of the INFORMATION_SCHEMA database than it is to select *.
A better query would be:
SELECT
COLUMN_NAME,
Case
When DATA_TYPE In ('varchar', 'char', 'nchar', 'nvarchar', 'binary')
Then convert(varchar(MAX), CHARACTER_MAXIMUM_LENGTH)
When DATA_TYPE In ('numeric', 'int', 'smallint', 'bigint', 'tinyint')
Then convert(varchar(MAX), NUMERIC_PRECISION)
When DATA_TYPE = 'bit'
Then convert(varchar(MAX), 1)
When DATA_TYPE IN ('decimal', 'float')
Then convert(varchar(MAX), Concat(Concat(NUMERIC_PRECISION, ', '), NUMERIC_SCALE))
When DATA_TYPE IN ('date', 'datetime', 'smalldatetime', 'time', 'timestamp')
Then ''
End As DATALEN,

I don't see df.write.saveAsTable(...)
deprecated in Spark 2.0 documentation. It has worked for us on Amazon EMR. We were perfectly able to read data from S3 into a dataframe, process it, create a table from the result and read it with MicroStrategy.
Vinays answer has also worked though.
You can use
document.getElementById("parentID").appendChild(/*..your content created using DOM methods..*/)
or
document.getElementById("parentID").innerHTML+= "new content"
If you don't want to use custom views or special layouts, you can use 9-patch to make the (X) button .
Example: http://postimg.org/image/tssjmt97p/ (I don't have enough points to post images on StackOverflow)
The intersection of the right and bottom black pixels represent the content area. Anything outside of that area is padding. So to detect that the user clicked on the x you can set a OnTouchListener like so:
editText.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
if (motionEvent.getAction() == MotionEvent.ACTION_UP){
if (motionEvent.getX()>(view.getWidth()-view.getPaddingRight())){
((EditText)view).setText("");
}
}
return false;
}
});
According to your needs this solution can work better in some cases. I prefer to keep my xml less complicated. This also helps if you want to have an icon on the left, as you can simply include it in the 9 patch.

I believe the intent was to rename System32, but so many applications hard-coded for that path, that it wasn't feasible to remove it.
SysWoW64 wasn't intended for the dlls of 64-bit systems, it's actually something like "Windows on Windows64", meaning the bits you need to run 32bit apps on a 64bit windows.
This article explains a bit:
"Windows x64 has a directory System32 that contains 64-bit DLLs (sic!). Thus native processes with a bitness of 64 find “their” DLLs where they expect them: in the System32 folder. A second directory, SysWOW64, contains the 32-bit DLLs. The file system redirector does the magic of hiding the real System32 directory for 32-bit processes and showing SysWOW64 under the name of System32."
Edit: If you're talking about an installer, you really should not hard-code the path to the system folder. Instead, let Windows take care of it for you based on whether or not your installer is running on the emulation layer.
you can add a download attribute to the anchor element.
sample:
<a download="abcd.cer"
href="data:application/stream;base64,MIIDhTC......">down</a>
with
statementDifferentiating between exceptions that occur in a with
statement is tricky because they can originate in different places. Exceptions can be raised from either of the following places (or functions called therein):
ContextManager.__init__
ContextManager.__enter__
with
ContextManager.__exit__
For more details see the documentation about Context Manager Types.
If we want to distinguish between these different cases, just wrapping the with
into a try .. except
is not sufficient. Consider the following example (using ValueError
as an example but of course it could be substituted with any other exception type):
try:
with ContextManager():
BLOCK
except ValueError as err:
print(err)
Here the except
will catch exceptions originating in all of the four different places and thus does not allow to distinguish between them. If we move the instantiation of the context manager object outside the with
, we can distinguish between __init__
and BLOCK / __enter__ / __exit__
:
try:
mgr = ContextManager()
except ValueError as err:
print('__init__ raised:', err)
else:
try:
with mgr:
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except ValueError as err:
# At this point we still cannot distinguish between exceptions raised from
# __enter__, BLOCK, __exit__ (also BLOCK since we didn't catch ValueError in the body)
pass
Effectively this just helped with the __init__
part but we can add an extra sentinel variable to check whether the body of the with
started to execute (i.e. differentiating between __enter__
and the others):
try:
mgr = ContextManager() # __init__ could raise
except ValueError as err:
print('__init__ raised:', err)
else:
try:
entered_body = False
with mgr:
entered_body = True # __enter__ did not raise at this point
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except ValueError as err:
if not entered_body:
print('__enter__ raised:', err)
else:
# At this point we know the exception came either from BLOCK or from __exit__
pass
The tricky part is to differentiate between exceptions originating from BLOCK
and __exit__
because an exception that escapes the body of the with
will be passed to __exit__
which can decide how to handle it (see the docs). If however __exit__
raises itself, the original exception will be replaced by the new one. To deal with these cases we can add a general except
clause in the body of the with
to store any potential exception that would have otherwise escaped unnoticed and compare it with the one caught in the outermost except
later on - if they are the same this means the origin was BLOCK
or otherwise it was __exit__
(in case __exit__
suppresses the exception by returning a true value the outermost except
will simply not be executed).
try:
mgr = ContextManager() # __init__ could raise
except ValueError as err:
print('__init__ raised:', err)
else:
entered_body = exc_escaped_from_body = False
try:
with mgr:
entered_body = True # __enter__ did not raise at this point
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except Exception as err: # this exception would normally escape without notice
# we store this exception to check in the outer `except` clause
# whether it is the same (otherwise it comes from __exit__)
exc_escaped_from_body = err
raise # re-raise since we didn't intend to handle it, just needed to store it
except ValueError as err:
if not entered_body:
print('__enter__ raised:', err)
elif err is exc_escaped_from_body:
print('BLOCK raised:', err)
else:
print('__exit__ raised:', err)
PEP 343 -- The "with" Statement specifies an equivalent "non-with" version of the with
statement. Here we can readily wrap the various parts with try ... except
and thus differentiate between the different potential error sources:
import sys
try:
mgr = ContextManager()
except ValueError as err:
print('__init__ raised:', err)
else:
try:
value = type(mgr).__enter__(mgr)
except ValueError as err:
print('__enter__ raised:', err)
else:
exit = type(mgr).__exit__
exc = True
try:
try:
BLOCK
except TypeError:
pass
except:
exc = False
try:
exit_val = exit(mgr, *sys.exc_info())
except ValueError as err:
print('__exit__ raised:', err)
else:
if not exit_val:
raise
except ValueError as err:
print('BLOCK raised:', err)
finally:
if exc:
try:
exit(mgr, None, None, None)
except ValueError as err:
print('__exit__ raised:', err)
The need for such special exception handling should be quite rare and normally wrapping the whole with
in a try ... except
block will be sufficient. Especially if the various error sources are indicated by different (custom) exception types (the context managers need to be designed accordingly) we can readily distinguish between them. For example:
try:
with ContextManager():
BLOCK
except InitError: # raised from __init__
...
except AcquireResourceError: # raised from __enter__
...
except ValueError: # raised from BLOCK
...
except ReleaseResourceError: # raised from __exit__
...

In case .empty() doesn't work for you, which is for me
function SetDropDownToEmpty()

}
$(document).ready(
SetDropDownToEmpty() ;

The reason why your X-axis plots frequencies only till 500 Hz is your command statement 'f = Fs/2*linspace(0,1,NFFT/2+1);'. Your Fs is 1000. So when you divide it by 2 & then multiply by values ranging from 0 to 1, it returns a vector of length NFFT/2+1. This vector consists of equally spaced frequency values, ranging from 0 to Fs/2 (i.e. 500 Hz). Since you plot using 'plot(f,2*abs(Y(1:NFFT/2+1)))' command, your X-axis limit is 500 Hz.
I'm not sure about Tomcat 7, but with Tomcat 6... once you start Tomcat:
By going into the bin directory and starting startup.bat
(win) or startup.sh
(Unix/osx) it will spin up a local instance of the server running usually on port 8080 by default. Then by going to http://localhost:8080/ and seeing that it is running, there is a link to the manager. If that page is not there, you can try loading the manager by going directly to manager/html, and that will load the Host Manager gui.
http://localhost:8080/manager/html
Make sure Tomcat is running first and that 8080 is the right port. These are just the defaults that tomcat usually runs with.
To login you need to edit the conf/tomcat-users.xml, and create a Manager GUI role
<role rolename="manager-gui"/>
and add that to a user
<user username="admin" password="password" roles="manager-gui"/>
Then when you go to Manager GUI app at http://localhost:8080/manager/html it will prompt you for a username/password, which you added to that config file.
If using ActiveAdmin don't forget that there is also a permit_params in the model register block:
ActiveAdmin.register Api::V1::Person do
permit_params :name, :address, :etc
end
These need to be set along with those in the controller:
def api_v1_person_params
params.require(:api_v1_person).permit(:name, :address, :etc)
end
Otherwise you will get the error:
ActiveModel::ForbiddenAttributesError

There are several you can use/try:
You are placing your result in the RETURN
value instead of in the passed @r
value.
From MSDN
(RETURN) Is the integer value that is returned. Stored procedures can return an integer value to a calling procedure or an application.
ALTER procedure S_Comp(@str1 varchar(20),@r varchar(100) out) as
declare @str2 varchar(100)
set @str2 ='welcome to sql server. Sql server is a product of Microsoft'
if(PATINDEX('%'+@str1 +'%',@str2)>0)
SELECT @r = @str1+' present in the string'
else
SELECT @r = @str1+' not present'
DECLARE @r VARCHAR(100)
EXEC S_Comp 'Test', @r OUTPUT
SELECT @r
load_tests is a little known mechanism introduced in 2.7 to dynamically create a TestSuite. With it, you can easily create parametrized tests.
For example:
import unittest
class GeneralTestCase(unittest.TestCase):
def __init__(self, methodName, param1=None, param2=None):
super(GeneralTestCase, self).__init__(methodName)
self.param1 = param1
self.param2 = param2
def runTest(self):
pass # Test that depends on param 1 and 2.
def load_tests(loader, tests, pattern):
test_cases = unittest.TestSuite()
for p1, p2 in [(1, 2), (3, 4)]:
test_cases.addTest(GeneralTestCase('runTest', p1, p2))
return test_cases
That code will run all the TestCases in the TestSuite returned by load_tests. No other tests are automatically run by the discovery mechanism.
Alternatively, you can also use inheritance as shown in this ticket: http://bugs.python.org/msg151444
Correct final syntax for [Mr. C]s answer.
With the release of VS2017RC and its C#7 support it works this way:
switch(message)
{
case string a when a.Contains("test2"): return "no";
case string b when b.Contains("test"): return "yes";
}
You should take care of the case ordering as the first match will be picked. That's why "test2" is placed prior to test.
The whole point of using a mapping technology like Jackson is that you can use Objects (you don't have to parse the JSON yourself).
Define a Java class that resembles the JSON you will be expecting.
e.g. this JSON:
{
"foo" : ["abc","one","two","three"],
"bar" : "true",
"baz" : "1"
}
could be mapped to this class:
public class Fizzle{
private List<String> foo;
private boolean bar;
private int baz;
// getters and setters omitted
}
Now if you have a Controller method like this:
@RequestMapping("somepath")
@ResponseBody
public Fozzle doSomeThing(@RequestBody Fizzle input){
return new Fozzle(input);
}
and you pass in the JSON from above, Jackson will automatically create a Fizzle object for you, and it will serialize a JSON view of the returned Object out to the response with mime type application/json
.
For a full working example see this previous answer of mine.
Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.
You've got:
//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]
Which translates into:
Get me all the elements that have an ID
that contains ctl00_btnAircraftMapCell
. Out of these elements, get any child elements that have a title
that contains Select Seat
.
What you actually want is:
//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]
Which translates into:
Get me all the anchor elements that have both: an id
that contains ctl00_btnAircraftMapCell
and a title
that contains Select Seat
.
To expand on Sparr's answer
Initialization and assignment are two distinct operations that happen to use the same operator ("=") here.
Think of it like this:
Imagine that there are 2 functions, called InitializeObject
, and AssignObject
. When the compiler sees thing = value
, it looks at the context and calls one InitializeObject
if you're making a new thing
. If you're not, it instead calls AssignObject
.
Normally this is fine as InitializeObject
and AssignObject
usually behave the same way. Except when dealing with char arrays (and a few other edge cases) in which case they behave differently. Why do this? Well that's a whole other post involving the stack vs the heap and so on and so forth.
PS: As an aside, thinking of it in this way will also help you understand copy constructors and other such things if you ever venture into C++
Hi I feel str_getcsv
— Parse a CSV string into an array is the best option for you.
You need to upload the file to sever
parse the file using str_getcsv.
run through the array and align as per u need in your website.
jQuery UI extends the jQuery native toggleClass
to take a second optional parameter: duration
toggleClass( class, [duration] )
For a simple two- (or one) liner this code can be:
checkboxes = document.getElementsByName("NameOfCheckboxes");
selectedCboxes = Array.prototype.slice.call(checkboxes).filter(ch => ch.checked==true);
Here the Array.prototype.slice.call()
part converts the object NodeList of all the checkboxes holding that name ("NameOfCheckboxes") into a new array, on which you then use the filter method. You can then also, for example, extract the values of the checkboxes by adding a .map(ch => ch.value)
on the end of line 2.
The => is javascript's arrow function notation.
This is what I use, but it is slow on large text files.
get-content $pathToFile | % { $_ -replace $stringToReplace, $replaceWith } | set-content $pathToFile
If you are going to be replacing strings in large text files and speed is a concern, look into using System.IO.StreamReader and System.IO.StreamWriter.
try
{
$reader = [System.IO.StreamReader] $pathToFile
$data = $reader.ReadToEnd()
$reader.close()
}
finally
{
if ($reader -ne $null)
{
$reader.dispose()
}
}
$data = $data -replace $stringToReplace, $replaceWith
try
{
$writer = [System.IO.StreamWriter] $pathToFile
$writer.write($data)
$writer.close()
}
finally
{
if ($writer -ne $null)
{
$writer.dispose()
}
}
(The code above has not been tested.)
There is probably a more elegant way to use StreamReader and StreamWriter for replacing text in a document, but that should give you a good starting point.
No, there is no difference. But I prefer using int[] array
as it is more readable.

Update:
I have added this link to my other answer how to use JWT authentication for ASP.NET Web API here for anyone interested in JWT.
We have managed to apply HMAC authentication to secure Web API, and it worked okay. HMAC authentication uses a secret key for each consumer which both consumer and server both know to hmac hash a message, HMAC256 should be used. Most of the cases, hashed password of the consumer is used as a secret key.
The message normally is built from data in the HTTP request, or even customized data which is added to HTTP header, the message might include:
Under the hood, HMAC authentication would be:
Consumer sends a HTTP request to web server, after building the signature (output of hmac hash), the template of HTTP request:
User-Agent: {agent}
Host: {host}
Timestamp: {timestamp}
Authentication: {username}:{signature}
Example for GET request:
GET /webapi.hmac/api/values

Please note that form data and query string should be in order, so the code on the server get query string and form data to build the correct message.
When HTTP request comes to the server, an authentication action filter is implemented to parse the request to get information: HTTP verb, timestamp, uri, form data and query string, then based on these to build signature (use hmac hash) with the secret key (hashed password) on the server.
The secret key is got from the database with the username on the request.
Then server code compares the signature on the request with the signature built; if equal, authentication is passed, otherwise, it failed.
The code to build signature:
private static string ComputeHash(string hashedPassword, string message)
{
var key = Encoding.UTF8.GetBytes(hashedPassword.ToUpper());
string hashString;
using (var hmac = new HMACSHA256(key))
{
var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(message));
hashString = Convert.ToBase64String(hash);
}
return hashString;
}
So, how to prevent replay attack?
Add constraint for the timestamp, something like:
servertime - X minutes|seconds <= timestamp <= servertime + X minutes|seconds
(servertime: time of request coming to server)
And, cache the signature of the request in memory (use MemoryCache, should keep in the limit of time). If the next request comes with the same signature with the previous request, it will be rejected.
The demo code is put as here: https://github.com/cuongle/Hmac.WebApi
Put 0 as default in SQL or add 0 into your area of table
I needed to do something like this really fast really simple, from searching for ideas i finally built this template. The idea is receive the weighted values in a form of a json from the api, which here is simulated by the dict.
Then translate it into a list in which each value repeats proportionally to it's weight, and just use random.choice to select a value from the list.
I tried it running with 10, 100 and 1000 iterations. The distribution seems pretty solid.
def weighted_choice(weighted_dict):
"""Input example: dict(apples=60, oranges=30, pineapples=10)"""
weight_list = []
for key in weighted_dict.keys():
weight_list += [key] * weighted_dict[key]
return random.choice(weight_list)
You don't want to delete if you're wanting to leave the row itself intact. You want to update the row, and change the column value.
The general form for this would be an UPDATE
statement:
UPDATE <table name>
SET
ColumnA = <NULL, or '', or whatever else is suitable for the new value for the column>
WHERE
ColumnA = <bad value> /* or any other search conditions */
I ran a test that just added 1 to the number instead of rand(). Results (on an x86-64) were:
There is GitPython. Haven’t heard of it before and internally, it relies on having the git executables somewhere; additionally, they might have plenty of bugs. But it could be worth a try.
How to clone:
import git
git.Git("/your/directory/to/clone").clone("git://gitorious.org/git-python/mainline.git")
(It’s not nice and I don’t know if it is the supported way to do it, but it worked.)
Define the parent with display: table
and the element itself with vertical-align: middle
and display: table-cell
.
In [1]: class test(object):
def __init__(self):
self.pants = 'pants'
@property
def p(self):
return self.pants
@p.setter
def p(self, value):
self.pants = value * 2
....:
In [2]: t = test()
In [3]: t.p
Out[3]: 'pants'
In [4]: t.p = 10
In [5]: t.p

You can use pandas library to read the JSON file.
import pandas as pd
df = pd.read_json('strings.json',lines=True)
print(df)
Along with forEach
method that accepts a lambda expression we have also got stream APIs, in Java 8.
Iterate over entries (Using forEach and Streams):
sample.forEach((k,v) -> System.out.println(k + "=" + v));
sample.entrySet().stream().forEachOrdered((entry) -> {
Object currentKey = entry.getKey();
Object currentValue = entry.getValue();
System.out.println(currentKey + "=" + currentValue);
});
sample.entrySet().parallelStream().forEach((entry) -> {
Object currentKey = entry.getKey();
Object currentValue = entry.getValue();
System.out.println(currentKey + "=" + currentValue);
});
The advantage with streams is they can be parallelized easily and can be useful when we have multiple CPUs at disposal. We simply need to use parallelStream()
in place of stream()
above. With parallel streams it makes more sense to use forEach
as forEachOrdered
would make no difference in performance. If we want to iterate over keys we can use sample.keySet()
and for values sample.values()
.
Why forEachOrdered
and not forEach
with streams ?
Streams also provide forEach
method but the behaviour of forEach
is explicitly nondeterministic where as the forEachOrdered
performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach
does not guarantee that the order would be kept. Also check this for more.

In my case the error occurred inside a Fragment
on this line:
Intent intent = new Intent(getActivity(), SecondaryActivity.class);
It happened when I double clicked on an item which triggered the code above so two SecondaryActivity.class
activities were launched at the same time, one on top of the other. I closed the top SecondaryActivity.class
activity by pressing back button which triggered a call to getActivity()
in the SecondaryActivity.class
which came to foreground. The call to getActivity()
returned null
.
It's some kind of weird Android bug so it usually should not happen.
You can block the clicks after the user clicked once.
<ul id="unOrderedList">
<li value="2">Whatever</li>
.
.
$('#unOrderedList li').click(function(){
var value = $(this).attr('value');
alert(value);
});
Your looking for the attribute "value" inside the "li" tag
There's a relatively new way of doing transparency, it's called HEXA (HEX + Alpha). It takes in 8 digits instead of 6. The last pair is Alpha. So the pattern of pairs is #RRGGBBAA. Having 4 digits also works: #RGBA
I am not sure about its browser support for now but, you can check the DRAFT Docs for more information.
§ 4.2. The RGB hexadecimal notations: #RRGGBB
The syntax of a
<hex-color>
is a<hash-token>
token whose value consists of 3, 4, 6, or 8 hexadecimal digits. In other words, a hex color is written as a hash character, "#", followed by some number of digits0-9
or lettersa-f
(the case of the letters doesn’t matter -#00ff00
is identical to#00FF00
).8 digits
The first 6 digits are interpreted identically to the 6-digit notation. The last pair of digits, interpreted as a hexadecimal number, specifies the alpha channel of the color, where
00
represents a fully transparent color andff
represent a fully opaque color.Example 3
In other words,#0000ffcc
represents the same color asrgba(0, 0, 100%, 80%)
(a slightly-transparent blue).4 digits
This is a shorter variant of the 8-digit notation, "expanded" in the same way as the 3-digit notation is. The first digit, interpreted as a hexadecimal number, specifies the red channel of the color, where
0
represents the minimum value andf
represents the maximum. The next three digits represent the green, blue, and alpha channels, respectively.
For the most part, Chrome and Firefox have started supporting this:

TL:DR; return promises from you actions only when necessary, but DRY chaining the same actions.
For a long time I also though that returning actions contradicts the Vuex cycle of uni-directional data flow.
But, there are EDGE CASES where returning a promise from your actions might be "necessary".
Imagine a situation where an action can be triggered from 2 different components, and each handles the failure case differently. In that case, one would need to pass the caller component as a parameter to set different flags in the store.
Dumb example
Page where the user can edit the username in navbar and in /profile page (which contains the navbar). Both trigger an action "change username", which is asynchronous. If the promise fails, the page should only display an error in the component the user was trying to change the username from.
Of course it is a dumb example, but I don't see a way to solve this issue without duplicating code and making the same call in 2 different actions.
Built a modal popup example using syarul's jsFiddle link. Here is the updated fiddle.
Created an angular directive called modal and used in html. Explanation:-
HTML
<div ng-controller="MainCtrl" class="container">
<button ng-click="toggleModal('Success')" class="btn btn-default">Success</button>
<button ng-click="toggleModal('Remove')" class="btn btn-default">Remove</button>
<button ng-click="toggleModal('Deny')" class="btn btn-default">Deny</button>
<button ng-click="toggleModal('Cancel')" class="btn btn-default">Cancel</button>
<modal visible="showModal">
Any additional data / buttons
</modal>
</div>
On button click toggleModal() function is called with the button message as parameter. This function toggles the visibility of popup. Any tags that you put inside will show up in the popup as content since ng-transclude is placed on modal-body in the directive template.
JS
var mymodal = angular.module('mymodal', []);
mymodal.controller('MainCtrl', function ($scope) {
$scope.showModal = false;
$scope.buttonClicked = "";
$scope.toggleModal = function(btnClicked){
$scope.buttonClicked = btnClicked;
$scope.showModal = !$scope.showModal;
};
});
mymodal.directive('modal', function () {
return {
template: '<div class="modal fade">' +
'<div class="modal-dialog">' +
'<div class="modal-content">' +
'<div class="modal-header">' +
'<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>' +
'<h4 class="modal-title">{{ buttonClicked }} clicked!!</h4>' +
'</div>' +
'<div class="modal-body" ng-transclude></div>' +
'</div>' +
'</div>' +
'</div>',
restrict: 'E',
transclude: true,
replace:true,
scope:true,
link: function postLink(scope, element, attrs) {
scope.title = attrs.title;
scope.$watch(attrs.visible, function(value){
if(value == true)
$(element).modal('show');
else
$(element).modal('hide');
});
$(element).on('shown.bs.modal', function(){
scope.$apply(function(){
scope.$parent[attrs.visible] = true;
});
});
$(element).on('hidden.bs.modal', function(){
scope.$apply(function(){
scope.$parent[attrs.visible] = false;
});
});
}
};
});

UPDATE 2 restrict : 'E' : directive to be used as an HTML tag (element). Example in our case is

Other values are 'A' for attribute
<div modal>
'C' for class (not preferable in our case because modal is already a class in bootstrap.css)
<div class="modal">
Boris Smus's article High DPI Images for Variable Pixel Densities has a more accurate definition of device pixel ratio: the number of device pixels per CSS pixel is a good approximation, but not the whole story.
Note that you can get the DPR used by a device with window.devicePixelRatio
.
I had some problems with andy's code, but it gave me some great ideas. First problem was that we should pop off any jqXHR objects that successfully complete. I also had to modify the abortAll function. Here is my final working code:
$.xhrPool = [];
$.xhrPool.abortAll = function() {
$(this).each(function(idx, jqXHR) {
jqXHR.abort();
});
};
$.ajaxSetup({
beforeSend: function(jqXHR) {
$.xhrPool.push(jqXHR);
}
});
$(document).ajaxComplete(function() {
$.xhrPool.pop();
});
I didn't like the ajaxComplete() way of doing things. No matter how I tried to configure .ajaxSetup it did not work.
"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.
Check that you don't send ANY content before calling session_start
. Better yet, just make session_start
the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).
You check if it's null
in C# like this:
if(MyObject != null) {
//do something
}
If you want to check against default (tough to understand the question on the info given) check:
if(MyObject != default(MyObject)) {
//do something
}
A proper way to search for a substring is to use position
function instead of like
expression, which requires escaping %
, _
and an escape character (\
by default):
SELECT id FROM TAG_TABLE WHERE position(tag_name in 'aaaaaaaaaaa')>0;
we have also dismiss our dialog on onPause
method or onDestroy
method
@Override
protected void onPause() {
super.onPause();
dialog.dismiss();
}
@Override
protected void onDestroy() {
super.onDestroy();
dialog.dismiss();
}
Use media queries. Your CSS code would be:
@media screen and (max-width: 1024px) {
.yourClass {
display: none !important;
}
}
You also could use simpler regex designed for your case like (.*)\/(([^\?\n\r])*)
where $2
match what you want.
str(n).zfill(width)
will work with string
s, int
s, float
s... and is Python 2.x and 3.x compatible:
>>> n = 3
>>> str(n).zfill(5)
'00003'
>>> n = '3'
>>> str(n).zfill(5)
'00003'
>>> n = '3.0'
>>> str(n).zfill(5)
'003.0'
I was also looking for this, but didn't want to impersonate a user to simply acquire a path!
user_path=$(grep $username /etc/passwd|cut -f6 -d":");
Now in your script, you can refer to $user_path
in most cases would be /home/username
Assumes: You have previously set $username
with the value of the intended users username.

That's because you're getting the numeric value associated with the class. For example if you have two classes cats and dogs, Keras will associate them numeric values 0 and 1. To get the mapping between your classes and their associated numeric value, you can use
>>> classes = train_generator.class_indices
>>> print(classes)
{'cats': 0, 'dogs': 1}
Now you know the mapping between your classes and indices. So now what you can do is
if classes[0][0] == 1:
prediction = 'dog'
else:
prediction = 'cat'
For chrome, I have used something like this and it worked out for me.
Within the body tag,
<body style="-webkit-print-color-adjust: exact;"> </body>
Or for a particular element, let's say if you have table and you want to fill a td i.e a cell,
<table><tr><td style="-webkit-print-color-adjust: exact;"></tr></table>
.find(:all, where: "value LIKE product_%", params: { limit: 20, page: 1 })

Its very simple to send emails on localhost or local server
Note: I am using the test mail server software on Windows 7 64bit with Xampp installed
Just download test mail server tool and install according to the instruction given on its website Test Mail Server Tool
Now you need to change only two lines under php.ini
file
[mail function]
and remove semi colon which is before ;smtp = localhost
sendmail_path = "C:\xampp\mailtodisk\mailtodisk.exe"
You don't need to change anything else, but if you still not getting emails than check for the SMTP port
, the port number must be same.
The above method is for default settings provided by the Xampp software.
In case above-accepted answer did not work, try below solution. You can use it for port 8080 or for any other ports.
sudo lsof -i tcp:3000
Replace 3000 with whichever port you want. Run below command to kill that process.
sudo kill -9 PID
PID is process ID you want to kill.
Below is the output of commands on mac Terminal.
There's no difference at all, VanillaJS
is just a way to refer to native (non-extended and standards-based) JavaScript. Generally speaking it's a term of contrast when using libraries and frameworks like jQuery and React. Website www.vanilla-js.com lays emphasis on it as a joke, by talking 'bout VanillaJS
as though it were a fast, lightweight, and cross-platform framework. That muddies the waters! Thus, it can be a little philosophical question: "how many things do I compile to Vanilla JavaScript
without being VanillaJS
themselves?" So, a mere guideline for that is: if you can write the code and run it in any current web-browser without additional tools or so called compile steps, it might be VanillaJS
.
Create a dictionary, then iterate over the result and stuff the rows in the dictionary. Note that if you encounter a row with a duplicate date, you will have to decide what to do (raise an exception, replace the previous row, discard the later row, etc...)
Here's test.csv:
Date,Foo,Bar
123,456,789
abc,def,ghi
and the corresponding program:
import csv
reader = csv.reader(open('test.csv'))
result = {}
for row in reader:
key = row[0]
if key in result:
# implement your duplicate row handling here
pass
result[key] = row[1:]
print(result)
yields:
{'Date': ['Foo', 'Bar'], '123': ['456', '789'], 'abc': ['def', 'ghi']}
or, with DictReader:
import csv
reader = csv.DictReader(open('test.csv'))
result = {}
for row in reader:
key = row.pop('Date')
if key in result:
# implement your duplicate row handling here
pass
result[key] = row
print(result)
results in:
{'123': {'Foo': '456', 'Bar': '789'}, 'abc': {'Foo': 'def', 'Bar': 'ghi'}}
Or perhaps you want to map the column headings to a list of values for that column:
import csv
reader = csv.DictReader(open('test.csv'))
result = {}
for row in reader:
for column, value in row.items(): # consider .iteritems() for Python 2
result.setdefault(column, []).append(value)
print(result)
That yields:
{'Date': ['123', 'abc'], 'Foo': ['456', 'def'], 'Bar': ['789', 'ghi']}
Try doing this :
recipients="[email protected],[email protected],[email protected]"
And another approach, using shell here-doc :
/usr/sbin/sendmail "$recipients" <<EOF
subject:$subject
from:$from
Example Message
EOF
Be sure to separate the headers from the body with a blank line as per RFC 822.
For Android 10 there is background restrictions.
For android 10 and all version of android follow this steps to start an app after a restart or turn on mobile
Add this two permission in Android Manifest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
Add this in your application tag

You can use delegate_to
to run commands on your Ansible host (admin host), from where you are running your Ansible play. For example:
Delete a file if it already exists on Ansible host:
- name: Remove file if already exists
file:
path: /tmp/logfile.log
state: absent
mode: "u+rw,g-wx,o-rwx"
delegate_to: 127.0.0.1
Create a new file on Ansible host :
- name: Create log file
file:
path: /tmp/logfile.log
state: touch
mode: "u+rw,g-wx,o-rwx"
delegate_to: 127.0.0.1

folder into data
folder. This worked for me. This Answer seems to be
bit helpful while declaring the large numbe of variable in the function
Laravel 5.7.*
For Example
public function index()
{
$activePost = Post::where('status','=','active')->get()->count();
$inActivePost = Post::where('status','=','inactive')->get()->count();
$yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();
$todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();
return view('dashboard.index')->with('activePost',$activePost)->with('inActivePost',$inActivePost )->with('yesterdayPostActive',$yesterdayPostActive )->with('todayPostActive',$todayPostActive );
}
When you see the last line of the returns it not looking good
When You Project is Getting Larger its not good
So
public function index()
{
$activePost = Post::where('status','=','active')->get()->count();
$inActivePost = Post::where('status','=','inactive')->get()->count();
$yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();
$todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();
$viewShareVars = ['activePost','inActivePost','yesterdayPostActive','todayPostActive'];
return view('dashboard.index',compact($viewShareVars));
}
As You see all the variables as declared as array of $viewShareVars
and Accessed in View
But My Function Becomes very Larger so i have decided to make the line as very simple
public function index()
{
$activePost = Post::where('status','=','active')->get()->count();
$inActivePost = Post::where('status','=','inactive')->get()->count();
$yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();
$todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();
$viewShareVars = array_keys(get_defined_vars());
return view('dashboard.index',compact($viewShareVars));
}
the native php function get_defined_vars()
get all the defined variables from the function
and array_keys
will grab the variable names
so in your view you can access all the declared variable inside the function
as {{$todayPostActive}}
The problem was that I needed to have both minGW and MSYS installed and added to PATH.
The problem is now fixed.
Use .length
to count number of characters, and $.trim()

It makes sense that constructors complete their execution in order of derivation. Because a superclass has no knowledge of any subclass, any initialization it needs to perform is separate from and possibly prerequisite to any initialization performed by the subclass. Therefore, it must complete its execution first.
A simple demonstration:
class A {
A() {
System.out.println("Inside A's constructor.");
}
}
class B extends A {
B() {
System.out.println("Inside B's constructor.");
}
}
class C extends B {
C() {
System.out.println("Inside C's constructor.");
}
}
class CallingCons {
public static void main(String args[]) {
C c = new C();
}
}
The output from this program is:
Inside A's constructor
Inside B's constructor
Inside C's constructor
I am using EF Core with ASP.NET Core V2.2.6. @Richard Logwood's answer was great and it solved my problem, but I needed a different syntax.
So, For those using EF Core with ASP.NET Core V2.2.6 +...
instead of
Update-Database <Name of last good migration>
I had to use:
dotnet ef database update <Name of last good migration>
And instead of
Remove-Migration
I had to use:
dotnet ef migrations remove
For --help
i had to use :
dotnet ef migrations --help
Usage: dotnet ef migrations [options] [command]
Options:
-h|--help Show help information
-v|--verbose Show verbose output.
--no-color Don't colorize output.
--prefix-output Prefix output with level.
Commands:
add Adds a new migration.
list Lists available migrations.
remove Removes the last migration.
script Generates a SQL script from migrations.
Use "migrations [command] --help" for more information about a command.
This let me role back to the stage where my DB worked as expected, and start from beginning.
The top answers led to a bug in my code where on the first of the month it would set a future date in the current month. Here is what I did,
curDate = new Date(); // Took current date as an example
prvDate = new Date(0); // Date set to epoch 0
prvDate.setUTCMilliseconds((curDate - (5 * 24 * 60 * 60 * 1000))); //Set epoch time
Set is used for setting object references, as opposed to assigning a value.
$content = '';
for($rowth=0; $rowth<=100; $rowth++){
$content .= $selenium->getTable("tblReports.{$rowth}.0") . "\n";
//$content .= $selenium->getTable("tblReports.{$rowth}.1") . "\n";
$content .= $selenium->getTable("tblReports.{$rowth}.2") . " ";
$content .= $selenium->getTable("tblReports.{$rowth}.3") . " ";
$content .= $selenium->getTable("tblReports.{$rowth}.4") . " ";
$content .= $selenium->getTable("tblReports.{$rowth}.5") . " ";
$content .= $selenium->getTable("tblReports.{$rowth}.6") . "\n";
}
This can be achieved by
<input type="file" accept="image/*" />
But this is not a good way. you have to code on the server side to check the file an image or not.
Check if image file is an actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
}
else {
echo "File is not an image.";
$uploadOk = 0;
}
}

To address the original question regarding performance, it comes down to index utilization. When a simple table scan occurs, "LIKE" and "=" are identical. When indexes are involved, it depends on how the LIKE clause is formed. More specifically, what is the location of the wildcard(s)?
Consider the following:
CREATE TABLE test(
txt_col varchar(10) NOT NULL
)
go
insert test (txt_col)
select CONVERT(varchar(10), row_number() over (order by (select 1))) r
from master..spt_values a, master..spt_values b
go
CREATE INDEX IX_test_data
ON test (txt_col);
go
--Turn on Show Execution Plan
set statistics io on
--A LIKE Clause with a wildcard at the beginning
DBCC DROPCLEANBUFFERS
SELECT txt_Col from test where txt_col like '%10000'
--Results in
--Table 'test'. Scan count 3, logical reads 15404, physical reads 2, read-ahead reads 15416, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
--Index SCAN is 85% of Query Cost
--A LIKE Clause with a wildcard in the middle
DBCC DROPCLEANBUFFERS
SELECT txt_Col from test where txt_col like '1%99'
--Results in
--Table 'test'. Scan count 1, logical reads 3023, physical reads 3, read-ahead reads 3018, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
--Index Seek is 100% of Query Cost for test data, but it may result in a Table Scan depending on table size/structure
--A LIKE Clause with no wildcards
DBCC DROPCLEANBUFFERS
SELECT txt_Col from test where txt_col like '10000'
--Results in
--Table 'test'. Scan count 1, logical reads 3, physical reads 2, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
--Index Seek is 100% of Query Cost
GO
--an "=" clause = does Index Seek same as above
DBCC DROPCLEANBUFFERS
SELECT txt_Col from test where txt_col = '10000'
--Results in
--Table 'test'. Scan count 1, logical reads 3, physical reads 2, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
--Index Seek is 100% of Query Cost
GO
DROP TABLE test
There may be also negligible difference in the creation of the query plan when using "=" vs "LIKE".
I have programmed a module wich is able to hash big files with different algorithms.
pip3 install py_essentials
Use the module like this:
from py_essentials import hashing as hs
hash = hs.fileChecksum("path/to/the/file.txt", "sha256")
Besides using Start-Process -Wait
, piping the output of an executable will make Powershell wait. Depending on the need, I will typically pipe to Out-Null
, Out-Default
, Out-String
or Out-String -Stream
. Here is a long list of some other output options.
# Saving output as a string to a variable.
$output = ping.exe example.com | Out-String
# Filtering the output.
ping stackoverflow.com | where { $_ -match '^reply' }
# Using Start-Process affords the most control.
Start-Process -Wait SomeExecutable.com
I do miss the CMD/Bash style operators that you referenced (&, &&, ||). It seems we have to be more verbose with Powershell.
.index.tolist()
is another function which you can get the index as a list:

Out[1391]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

Integer.TryParse(txtPrice.Text, decPrice)
decPrice = Convert.ToInt32(txtPrice.Text)

Thanks to the fantastic answer from Glenn, I used ImageMagik's "mogrify *.png" functionality. However, I had images buried in sub-folders, so I used this simple Python script to apply this to all images in all sub-folders and thought it might help others:
import os
import subprocess
def system_call(args, cwd="."):
print("Running '{}' in '{}'".format(str(args), cwd))
subprocess.call(args, cwd=cwd)
pass
def fix_image_files(root=os.curdir):
for path, dirs, files in os.walk(os.path.abspath(root)):
# sys.stdout.write('.')
for dir in dirs:
system_call("mogrify *.png", "{}".format(os.path.join(path, dir)))
fix_image_files(os.curdir)
I realize this is stale for a while and an answer had been selected, but how about the alternative to allow the foreign key to be NULL and then choose ON DELETE SET NULL.
Basically, your table should be changed like so:
ALTER TABLE 'bericht'
DROP FOREIGN KEY 'your_foreign_key';
ALTER TABLE 'bericht'
ADD CONSTRAINT 'your_foreign_key' FOREIGN KEY ('column_foreign_key') REFERENCES 'other_table' ('column_parent_key') ON UPDATE CASCADE ON DELETE SET NULL;
Personally I would recommend using both "ON UPDATE CASCADE" as well as "ON DELETE SET NULL" to avoid unnecessary complications, however your set up may dictate a different approach.
Hope this helps.
as @fabrizio-valencia said use lower case. in windows if you export mysql database (phpmyadmin) the tables name will converted to lower case and this lead to all sort of problems. see Are table names in MySQL case sensitive?
Technically the answer of zlovelady is preferable, but as I had only to remove items from the navigation, the approach of unsetting the not-needed navigation items in the template was the fastest/easiest way for me:
Just duplicate
app/design/frontend/base/default/template/customer/account/navigation
to
app/design/frontend/YOUR_THEME/default/template/customer/account/navigation
and unset the unneeded navigation items before the get rendered, e.g.:
<?php $_links = $this->getLinks(); ?>
<?php
unset($_links['recurring_profiles']);
?>
Unlike other source control systems like SVN or CVS, git stores all of its metadata in a single directory, rather than in every subdirectory of the project. So just delete .git
from the root (or use a script like git-export) and you should be fine.
For multicolumn listbox extract data from any column of selected row by
listboxControl.List(listboxControl.ListIndex,col_num)
where col_num is required column ( 0 for first column)
AssemblyVersion
pretty much stays internal to .NET, while AssemblyFileVersion
is what Windows sees. If you go to the properties of an assembly sitting in a directory and switch to the version tab, the AssemblyFileVersion
is what you'll see up top. If you sort files by version, this is what's used by Explorer.
The AssemblyInformationalVersion
maps to the "Product Version" and is meant to be purely "human-used".
AssemblyVersion
is certainly the most important, but I wouldn't skip AssemblyFileVersion
, either. If you don't provide AssemblyInformationalVersion
, the compiler adds it for you by stripping off the "revision" piece of your version number and leaving the major.minor.build.
There is no Javascript API to send ping frames or receive pong frames. This is either supported by your browser, or not. There is also no API to enable, configure or detect whether the browser supports and is using ping/pong frames. There was discussion about creating a Javascript ping/pong API for this. There is a possibility that pings may be configurable/detectable in the future, but it is unlikely that Javascript will be able to directly send and receive ping/pong frames.
However, if you control both the client and server code, then you can easily add ping/pong support at a higher level. You will need some sort of message type header/metadata in your message if you don't have that already, but that's pretty simple. Unless you are planning on sending pings hundreds of times per second or have thousands of simultaneous clients, the overhead is going to be pretty minimal to do it yourself.
According to http://www.php.net/manual/en/function.is-numeric.php, is_numeric alows something like "+0123.45e6" or "0xFF". I think this not what you expect.
preg_match can be slow, and you can have something like 0000 or 0051.
I prefer using ctype_digit (works only with strings, it's ok with $_GET).
<?php
$id = $_GET['id'];
if (ctype_digit($id)) {
echo 'ok';
} else {
echo 'nok';
}
?>
you can find your answer in the combination of these two pages in the API:
ref is used to register a reference to an element or a child component. The reference will be registered under the parent component’s $refs object. If used on a plain DOM element, the reference will be that element
An object that holds child components that have ref registered.
You can also have something like this:
class Entity {
id: number;
constructor(id: number) {
this.id = id;
}
clone(): this {
return new (this.constructor as typeof Entity)(this.id) as this;
}
}
class Customer extends Entity {
name: string;
constructor(id: number, name: string) {
super(id);
this.name = name;
}
clone(): this {
return new (this.constructor as typeof Customer)(this.id, this.name) as this;
}
}
Just make sure that you override the clone
method in all Entity
subclasses otherwise you'll end up with partial clones.
The return type of this
will always match the type of the instance.
If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide()
, with additional arguments, as follows:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this).hide('slide',{direction:'right'},1000);
});
});
Without using jQuery UI, you could achieve your aim just using animate()
:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this)
.animate(
{
'margin-left':'1000px'
// to move it towards the right and, probably, off-screen.
},1000,
function(){
$(this).slideUp('fast');
// once it's finished moving to the right, just
// removes the the element from the display, you could use
// `remove()` instead, or whatever.
}
);
});
});
If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js
$foobar = new foobar;
put the class foobar in $foobar, not the object. To get the object, you need to add parenthesis: $foobar = new foobar();
Your error is simply that you call a method on a class, so there is no $this
since $this
only exists in objects.
As mentioned by tripleee in the question comments , use moreutils ifne
(if input not empty).
In this case we want ifne -n
which negates the test:
ls -A /tmp/empty | ifne -n command-to-run-if-empty-input
The advantage of this over many of the another answers when the output of the initial command is non-empty. ifne
will start writing it to STDOUT straight away, rather than buffering the entire output then writing it later, which is important if the initial output is slowly generated or extremely long and would overflow the maximum length of a shell variable.
There are a few utils in moreutils that arguably should be in coreutils -- they're worth checking out if you spend a lot of time living in a shell.
In particular interest to the OP may be dirempty/exists
tool which at the time of writing is still under consideration, and has been for some time (it could probably use a bump).
Here ngOnChanges will trigger always when your input property changes:
ngOnChanges(changes: SimpleChanges): void {
console.log(changes.categoryId.currentValue)
}
You can use the Distinct
method to return an IEnumerable<T>
of distinct items:
var uniqueItems = yourList.Distinct();
And if you need the sequence of unique items returned as a List<T>
, you can add a call to ToList
:
var uniqueItemsList = yourList.Distinct().ToList();
I have managed to achieve this using this XML code only. It might be the case that eclipse does not render the height to show it expanding to fit; however, when you actually run this on a device, it properly renders and provides the desired result. (well at least for me)

android:layout_height="wrap_content">

tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.
If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.
You can do it in a shorthand as:
_.uniq(foo, 'a')
Sorry my previous answer was wrong. If you are trying to take total elapsed time between time and timeout in the format Y-m-d H:i:s format, take diff between timeout and time in using DateTime object and format it as '%y-%m-%d %H:%i:%s'.
This happens if you initialized a new github repo with README
and/or LICENSE
file
git remote add origin [//your github url]
//pull those changes
git pull origin master
// or optionally, 'git pull origin master --allow-unrelated-histories' if you have initialized repo in github and also committed locally
//now, push your work to your new repo
git push origin master
Now you will be able to push your repository to github. Basically, you have to merge those new initialized files with your work. git pull
fetches and merges for you. You can also fetch and merge if that suits you.
For this you can use CSS3 background-size
property. Write like this:
#div2{
background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
-moz-background-size:100% 100%;
-webkit-background-size:100% 100%;
background-size:100% 100%;
height:180px;
width:200px;
border: 1px solid red;
}

To add to Jason's answer:
You can speed the process up (which might be helpful for very large exponents) using the binary expansion of the exponent. First calculate 5, 5^2, 5^4, 5^8 mod 221 - you do this by repeated squaring:
5^1 = 5(mod 221)
5^2 = 5^2 (mod 221) = 25(mod 221)
5^4 = (5^2)^2 = 25^2(mod 221) = 625 (mod 221) = 183(mod221)
5^8 = (5^4)^2 = 183^2(mod 221) = 33489 (mod 221) = 118(mod 221)
5^16 = (5^8)^2 = 118^2(mod 221) = 13924 (mod 221) = 1(mod 221)
5^32 = (5^16)^2 = 1^2(mod 221) = 1(mod 221)
Now we can write
55 = 1 + 2 + 4 + 16 + 32
so 5^55 = 5^1 * 5^2 * 5^4 * 5^16 * 5^32
= 5 * 25 * 625 * 1 * 1 (mod 221)
= 125 * 625 (mod 221)
= 125 * 183 (mod 183) - because 625 = 183 (mod 221)
= 22875 ( mod 221)
= 112 (mod 221)
You can see how for very large exponents this will be much faster (I believe it's log as opposed to linear in b, but not certain.)
actually I walked the same path a couple of month ago. there is no perfect answer to the question (that was asked here a couple of time) but there is one more sophisticated then the sqrt(r-r) etc answer and more easy to implent directly with RGB without moving to all kind of alternate color spaces. I found this formula here which is a low cost approximation of the quite complicated real formula (by the CIE which is the W3C of color, since this is a not finished quest, you can find older and simpler color difference equations there). good luck
Edit: For posterity, here's the relevant C code:
typedef struct {
unsigned char r, g, b;
} RGB;
double ColourDistance(RGB e1, RGB e2)
{
long rmean = ( (long)e1.r + (long)e2.r ) / 2;
long r = (long)e1.r - (long)e2.r;
long g = (long)e1.g - (long)e2.g;
long b = (long)e1.b - (long)e2.b;
return sqrt((((512+rmean)*r*r)>>8) + 4*g*g + (((767-rmean)*b*b)>>8));
}
using :<line number>
you can navigate to any line, thus :1
takes you to the first line.
You can just go with:
if(!$strings{$string}) ....
An internal table data is stored in the warehouse folder, whereas an external table data is stored at the location you mentioned in table creation.
So when you delete an internal table, it deletes the schema as well as the data under the warehouse folder, but for an external table it's only the schema that you will loose.
So when you want an external table back you again after deleting it, can create a table with the same schema again and point it to the original data location. Hope it is clear now.

This question has some good answers about different persistence methods in Hibernate. To answer your question directly, with save() the insert statement is executed immediately regardless of transaction state. It returns the inserted key so you can do something like this:
long newKey = session.save(myObj);
So use save() if you need an identifier assigned to the persistent instance immediately.
With persist(), the insert statement is executed in a transaction, not necessarily immediately. This is preferable in most cases.
Use persist() if you don't need the insert to happen out-of-sequence with the transaction and you don't need the inserted key returned.
I wanted a function that would join tables without requiring you to define the columns using an anonymous type selector, but had a hard time finding any. I ended up having to make my own. Hopefully this will help anyone in the future who searches for this:
private DataTable JoinDataTables(DataTable t1, DataTable t2, params Func<DataRow, DataRow, bool>[] joinOn)
{
DataTable result = new DataTable();
foreach (DataColumn col in t1.Columns)
{
if (result.Columns[col.ColumnName] == null)
result.Columns.Add(col.ColumnName, col.DataType);
}
foreach (DataColumn col in t2.Columns)
{
if (result.Columns[col.ColumnName] == null)
result.Columns.Add(col.ColumnName, col.DataType);
}
foreach (DataRow row1 in t1.Rows)
{
var joinRows = t2.AsEnumerable().Where(row2 =>
{
foreach (var parameter in joinOn)
{
if (!parameter(row1, row2)) return false;
}
return true;
});
foreach (DataRow fromRow in joinRows)
{
DataRow insertRow = result.NewRow();
foreach (DataColumn col1 in t1.Columns)
{
insertRow[col1.ColumnName] = row1[col1.ColumnName];
}
foreach (DataColumn col2 in t2.Columns)
{
insertRow[col2.ColumnName] = fromRow[col2.ColumnName];
}
result.Rows.Add(insertRow);
}
}
return result;
}
An example of how you might use this:
var test = JoinDataTables(transactionInfo, transactionItems,
(row1, row2) =>
row1.Field<int>("TransactionID") == row2.Field<int>("TransactionID"));
One caveat: This is certainly not optimized, so be mindful when getting to row counts above 20k. If you know that one table will be larger than the other, try to put the smaller one first and the larger one second.
You cannot use Set Transaction Isolation Level Read Uncommitted in a View (you can only have one script in there in fact), so you would have to use (nolock) if dirty rows should be included.
Another thing use "", there is a difference between "\r\n" and '\r\n'.
I know that this is an old question, but the ignore-unresolvable
property was not working for me and I didn't know why.
The problem was that I needed an external resource (something like location="file:${CATALINA_HOME}/conf/db-override.properties"
) and the ignore-unresolvable="true"
does not do the job in this case.
What one needs to do for ignoring a missing external resource is:
ignore-resource-not-found="true"

The steps to apply a theme are fairly simple. To really understand how everything works together, you'll need to understand what the ASP.NET MVC 5 template is providing out of the box and how you can customize it for your needs.
Note: If you have a basic understanding of how the MVC 5 template works, scroll down to the theming section.
This walk-through goes over how to create an MVC 5 project and what's going on under the hood. See all the features of MVC 5 Template in this blog.
Create a new project. Under Templates Choose Web > ASP.NET Web Application. Enter a name for your project and click OK.
On the next wizard, choose MVC and click OK. This will apply the MVC 5 template.
The MVC 5 template creates an MVC application that uses Bootstrap to provide responsive design and theming features. Under the hood, the template includes a bootstrap 3.* nuget package that installs 4 files: bootstrap.css
, bootstrap.min.css
, bootstrap.js
, and bootstrap.min.js
.
Bootstrap is bundled in your application by using the Web Optimization feature. Inspect Views/Shared/_Layout.cshtml
and look for
@Styles.Render("~/Content/css")
and
@Scripts.Render("~/bundles/bootstrap")
These two paths refer to bundles set up in App_Start/BundleConfig.cs
:
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js",
"~/Scripts/respond.js"));
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css"));
This is what makes it possible to run your application without any configuring up front. Try running your project now.
This walk-through covers how to apply bootstrap themes in an MVC 5 project
css
of the theme you'd like to apply. For this example, I'll be using Bootswatch's Flatly. Include the downloaded flatly.bootstrap.css
and flatly.bootstrap.min.css
in the Content
folder (be sure to Include in Project as well).Open App_Start/BundleConfig.cs
and change the following:
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css"));
to include your new theme:
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/flatly.bootstrap.css",
"~/Content/site.css"));
If you're using the default _Layout.cshtml
included in the MVC 5 template, you can skip to step 4. If not, as a bare minimum, include these two line in your layout along with your Bootstrap HTML template:
In your <head>
:
@Styles.Render("~/Content/css")
Last line before closing </body>
:
@Scripts.Render("~/bundles/bootstrap")
Try running your project now. You should see your newly created application now using your theme.
Check out this awesome 30 day walk-through guide by James Chambers for more information, tutorials, tips and tricks on how to use Twitter Bootstrap with ASP.NET MVC 5.
if (select == "") {
alert("Please select a selection");
return false;
That should work for you. It just did for me.
I had the same problem. It might differ depending on how You put the data to the db, but try what worked for me:
$str = json_encode($data);
$str = addslashes($str);
Do this before saving data to db.
I doubt css understands left
by itself. You need to use it specifying position. You are using .css() correctly
position: relative/absolute/whatever;
left: 900px;
heres a fiddle of it working
and without the position here's what you get
Change your if statement to be like this - with quotes around -900px
var n = $("items").css("left");
if(n == '-900px'){
$(".items span").fadeOut("slow");
}
