You can use method getDate():
$('#calendar').datepicker({
dateFormat: 'yy-m-d',
inline: true,
onSelect: function(dateText, inst) {
var date = $(this).datepicker('getDate'),
day = date.getDate(),
month = date.getMonth() + 1,
year = date.getFullYear();
alert(day + '-' + month + '-' + year);
}
});
If you are using EF6 (Entity Framework 6+), this has changed for database calls to SQL.
See: http://msdn.microsoft.com/en-us/data/dn456843.aspx
use context.Database.BeginTransaction.
using (var context = new BloggingContext()) { using (var dbContextTransaction = context.Database.BeginTransaction()) { try { context.Database.ExecuteSqlCommand( @"UPDATE Blogs SET Rating = 5" + " WHERE Name LIKE '%Entity Framework%'" ); var query = context.Posts.Where(p => p.Blog.Rating >= 5); foreach (var post in query) { post.Title += "[Cool Blog]"; } context.SaveChanges(); dbContextTransaction.Commit(); } catch (Exception) { dbContextTransaction.Rollback(); //Required according to MSDN article throw; //Not in MSDN article, but recommended so the exception still bubbles up } } }
Not sure you resolved this issue or not, but this is how I do it and it works on Android:
If you are looking to just repopulate the fields with the values that were posted in them, then just echo the post value back into the field, like so:
<input type="text" name="myField1" value="<?php echo isset($_POST['myField1']) ? $_POST['myField1'] : '' ?>" />
I think every process you make start executing the line you create so something like this...
pid=fork() at line 6. fork function returns 2 values
you have 2 pids, first pid=0 for child and pid>0 for parent
so you can use if to separate
.
/*
sleep(int time) to see clearly
<0 fail
=0 child
>0 parent
*/
int main(int argc, char** argv) {
pid_t childpid1, childpid2;
printf("pid = process identification\n");
printf("ppid = parent process identification\n");
childpid1 = fork();
if (childpid1 == -1) {
printf("Fork error !\n");
}
if (childpid1 == 0) {
sleep(1);
printf("child[1] --> pid = %d and ppid = %d\n",
getpid(), getppid());
} else {
childpid2 = fork();
if (childpid2 == 0) {
sleep(2);
printf("child[2] --> pid = %d and ppid = %d\n",
getpid(), getppid());
} else {
sleep(3);
printf("parent --> pid = %d\n", getpid());
}
}
return 0;
}
//pid = process identification
//ppid = parent process identification
//child[1] --> pid = 2399 and ppid = 2398
//child[2] --> pid = 2400 and ppid = 2398
//parent --> pid = 2398
WARNING: Using
Access-Control-Allow-Origin: *
can make your API/website vulnerable to cross-site request forgery (CSRF) attacks. Make certain you understand the risks before using this code.
It's very simple to solve if you are using PHP. Just add the following script in the beginning of your PHP page which handles the request:
<?php header('Access-Control-Allow-Origin: *'); ?>
If you are using Node-red you have to allow CORS in the node-red/settings.js
file by un-commenting the following lines:
// The following property can be used to configure cross-origin resource sharing
// in the HTTP nodes.
// See https://github.com/troygoode/node-cors#configuration-options for
// details on its contents. The following is a basic permissive set of options:
httpNodeCors: {
origin: "*",
methods: "GET,PUT,POST,DELETE"
},
If you are using Flask same as the question; you have first to install flask-cors
$ pip install -U flask-cors
Then include the Flask cors in your application.
from flask_cors import CORS
A simple application will look like:
from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app)
@app.route("/")
def helloWorld():
return "Hello, cross-origin-world!"
For more details, you can check the Flask documentation.
For problems where it seems to be an error on a line you think is correct, you can often remove/comment the line where the error appears to be and, if the error moves to the next line, there are two possibilities.
Either both lines have a problem or the previous line has a problem which is being carried forward. The most likely case is the second option (even more so if you remove another line and it moves again).
For example, the following Python program twisty_passages.py
:
xyzzy = (1 +
plugh = 7
generates the error:
File "twisty_passages.py", line 2
plugh = 7
^
SyntaxError: invalid syntax
despite the problem clearly being on line 1.
In your particular case, that is the problem. The parentheses in the line before your error line is unmatched, as per the following snippet:
# open parentheses: 1 2 3
# v v v
fi2=0.460*scipy.sqrt(1-(Tr-0.566)**2/(0.434**2)+0.494
# ^ ^
# close parentheses: 1 2
Depending on what you're trying to achieve, the solution may be as simple as just adding another closing parenthesis at the end, to close off the sqrt
function.
I can't say for certain since I don't recognise the expression off the top of my head. Hardly surprising if (assuming PSAT is the enzyme, and the use of the typeMolecule
identifier) it's to do with molecular biology - I seem to recall failing Biology consistently in my youth :-)
In addition to the string operations (MOVS/INS/STOS/CMPS/SCASB/W/D/Q etc.) mentioned in the other answers, I wanted to add that there are also more "modern" x86 assembly instructions that implicitly use at least EDI/RDI:
The SSE2 MASKMOVDQU
(and the upcoming AVX VMASKMOVDQU
) instruction selectively write bytes from an XMM register to memory pointed to by EDI/RDI.
The problem appears to be internal bubbling within the <video>
element ... so when you click on the "Play" button the code triggers and then the play button itself get triggered :(
I couldn't find a simple (reliable) way to stop the click bubbling through (logic tells me there should be a way, but... it escapes me right now)
Anyway, the solution I found to this was to put a transparent <div>
over the video sized to fit down to where the controls appear... so if you click on the div then your script controls play/pause but if the user clicks on the controls themselves then the <video>
element handles that for you.
The sample below was sized for my video so you may need to juggle sizes of the relative <div>
s but it should get you started
<div id="vOverlay" style="position:relative; width:600px; height:300px; z-index:2;"></div>
<video style="position:relative; top:-300px; z-index:1;width:600px;height:340px;" width="600" height="409" id=videoPlayer controls="controls">
<source src="video.mp4" type="video/mp4">
</video>
<script>
var v = document.getElementById('videoPlayer');
var vv = document.getElementById('vOverlay');
<!-- Auto play, Half volume -->
v.play()
v.volume = 0.5;
v.firstChild.nodeValue = "Play";
<!-- Play, Pause -->
vv.addEventListener('click',function(e){
if (!v.paused) {
console.log("pause playback");
v.pause();
v.firstChild.nodeValue = 'Pause';
} else {
console.log("start playback")
v.play();
v.firstChild.nodeValue = 'Play';
}
});
</script>
Yes it's the exact same thing in Python 2:
d.values()
In Python 3 (where dict.values
returns a view of the dictionary’s values instead):
list(d.values())
local_action
runs the command on the local server, not on the servers you specify in hosts
parameter.
Change your "Execute the script" task to
- name: Execute the script
command: sh /home/test_user/test.sh
and it should do it.
You don't need to repeat sudo in the command line because you have defined it already in the playbook.
According to Ansible Intro to Playbooks user
parameter was renamed to remote_user
in Ansible 1.4 so you should change it, too
remote_user: test_user
So, the playbook will become:
---
- name: Transfer and execute a script.
hosts: server
remote_user: test_user
sudo: yes
tasks:
- name: Transfer the script
copy: src=test.sh dest=/home/test_user mode=0777
- name: Execute the script
command: sh /home/test_user/test.sh
In my case, the problem occurred when writing in Kotlin and using IDEA 2020.3. Despite proper entries in build.gradle.kts. It turned out that the problem was when generating test functions by IDEA IDE (Alt + Insert). It generates the following code:
@Test
internal fun name () {
TODO ("Not yet implemented")
}
And the problem will be fixed after removing the "internal" modifier:
@Test
fun name () {
TODO ("Not yet implemented")
}
A nice solution that I've found is to do on UI something like:
<div *ngIf="isDataLoaded">
...Your page...
</div
Only when: isDataLoaded is true the page is rendered.
I prefer the following code to wait for 2 seconds.
for(int i=0; i<2 && driver.findElements(By.id("textbox")).size()==0 ; i++){
Thread.sleep(1000);
}
There're several NuGet packages which can help with formatting. In some cases the capabilities of string.Format
are enough, but you may want to auto-size columns based on content, at least.
ConsoleTableExt is a simple library which allows formatting tables, including tables without grid lines. (A more popular package ConsoleTables doesn't seem to support borderless tables.) Here's an example of formatting a list of objects with columns sized based on their content:
ConsoleTableBuilder
.From(orders
.Select(o => new object[] {
o.CustomerName,
o.Sales,
o.Fee,
o.Value70,
o.Value30
})
.ToList())
.WithColumn(
"Customer",
"Sales",
"Fee",
"70% value",
"30% value")
.WithFormat(ConsoleTableBuilderFormat.Minimal)
.WithOptions(new ConsoleTableBuilderOption { DividerString = "" })
.ExportAndWriteLine();
If you need more features than that, any console formatting can be achieved with CsConsoleFormat.† For example, here's formatting of a list of objects as a grid with fixed column width of 10, like in the other answers using string.Format
:
ConsoleRenderer.RenderDocument(
new Document { Color = ConsoleColor.Gray }
.AddChildren(
new Grid { Stroke = LineThickness.None }
.AddColumns(10, 10, 10, 10, 10)
.AddChildren(
new Div("Customer"),
new Div("Sales"),
new Div("Fee"),
new Div("70% value"),
new Div("30% value"),
orders.Select(o => new object[] {
new Div().AddChildren(o.CustomerName),
new Div().AddChildren(o.Sales),
new Div().AddChildren(o.Fee),
new Div().AddChildren(o.Value70),
new Div().AddChildren(o.Value30)
})
)
));
It may look more complicated than pure string.Format
, but now it can be customized. For example:
If you want to auto-size columns based on content, replace AddColumns(10, 10, 10, 10, 10)
with AddColumns(-1, -1, -1, -1, -1)
(-1
is a shortcut to GridLength.Auto
, you have more sizing options, including percentage of console window's width).
If you want to align number columns to the right, add { Align = Right }
to a cell's initializer.
If you want to color a column, add { Color = Yellow }
to a cell's initializer.
You can change border styles and more.
† CsConsoleFormat was developed by me.
you can do so by using the :before
or :after
pseudo. read more about it here http://astronautweb.co/snippet/font-awesome/
change your code to this
.lb-prev:hover {
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=100);
opacity: 1;
text-decoration: none;
}
.lb-prev:before {
font-family: FontAwesome;
content: "\f053";
font-size: 30px;
}
do the same for the other icons. you might want to adjust the color and height of the icons too. anyway here is the fiddle hope this helps
Download and extract for .tar.gz
:
const https = require("https");
const tar = require("tar");
https.get("https://url.to/your.tar.gz", function(response) {

strip: 1,
C: "some-dir"
})
);
});
The answer anhic gave can be very inefficient if you have a large database and the attribute name is present only in some of the documents.
To improve efficiency you can add a $match to the aggregation.
db.collection.aggregate(
{"$match": {"name" :{ "$ne" : null } } },
{"$group" : {"_id": "$name", "count": { "$sum": 1 } } },
{"$match": {"count" : {"$gt": 1} } },
{"$project": {"name" : "$_id", "_id" : 0} }
)
Say I need to delete an index filebeat-7.6.2-2020.04.30-000001
and I performed it using a curl DELETE option (curl -X DELETE "localhost:9200/filebeat-7.6.2-2020.04.30-000001?pretty"
) and results in an authentication problem as below;
{
"error" : {
"type" : "security_exception",
"reason" : "missing authentication credentials for REST request [/filebeat-7.6.2-2020.04.30-000001?pretty]"
},
"status" : 401
}
Here you should authenticate the curl request using the username and password you have provided for Elasticsearch. Try then
curl -X DELETE -u myelasticuser:myelasticpassword "localhost:9200/filebeat-7.6.2-2020.04.30-000001?pretty"
will results in { "acknowledged" : true }.
newlist = oldlist[::10]
This picks out every 10th element of the list.
You forgot to seek:
str.CopyTo(data);
data.Seek(0, SeekOrigin.Begin); // <-- missing line
byte[] buf = new byte[data.Length];
data.Read(buf, 0, buf.Length);

The standard algorithm is to use pointers to the start / end, and walk them inward until they meet or cross in the middle. Swap as you go.
Reverse ASCII string, i.e. a 0-terminated array where every character fits in 1 char
. (Or other non-multibyte character sets).
void strrev(char *head)
{
if (!head) return;
char *tail = head;
while(*tail) ++tail; // find the 0 terminator, like head+strlen
--tail; // tail points to the last real char
// head still points to the first
for( ; head < tail; ++head, --tail) {
// walk pointers inwards until they meet or cross in the middle
char h = *head, t = *tail;
*head = t; // swapping as we go
*tail = h;
}
}
// test program that reverses its args
#include <stdio.h>
int main(int argc, char **argv)
{
do {
printf("%s ", argv[argc-1]);
strrev(argv[argc-1]);
printf("%s\n", argv[argc-1]);
} while(--argc);
return 0;
}
The same algorithm works for integer arrays with known length, just use tail = start + length - 1
instead of the end-finding loop.
(Editor's note: this answer originally used XOR-swap for this simple version, too. Fixed for the benefit of future readers of this popular question. XOR-swap is highly not recommended; hard to read and making your code compile less efficiently. You can see on the Godbolt compiler explorer how much more complicated the asm loop body is when xor-swap is compiled for x86-64 with gcc -O3.)
(This is XOR-swap thing. Take care to note that you must avoid swapping with self, because if *p
and *q
are the same location you'll zero it with a^a==0. XOR-swap depends on having two distinct locations, using them each as temporary storage.)
Editor's note: you can replace SWP with a safe inline function using a tmp variable.
#include <bits/types.h>
#include <stdio.h>
#define SWP(x,y) (x^=y, y^=x, x^=y)
void strrev(char *p)
{
char *q = p;
while(q && *q) ++q; /* find eos */
for(--q; p < q; ++p, --q) SWP(*p, *q);
}
void strrev_utf8(char *p)
{
char *q = p;
strrev(p); /* call base case */
/* Ok, now fix bass-ackwards UTF chars. */
while(q && *q) ++q; /* find eos */
while(p < --q)
switch( (*q & 0xF0) >> 4 ) {
case 0xF: /* U+010000-U+10FFFF: four bytes. */
SWP(*(q-0), *(q-3));
SWP(*(q-1), *(q-2));
q -= 3;
break;
case 0xE: /* U+000800-U+00FFFF: three bytes. */
SWP(*(q-0), *(q-2));
q -= 2;
break;
case 0xC: /* fall-through */
case 0xD: /* U+000080-U+0007FF: two bytes. */
SWP(*(q-0), *(q-1));
q--;
break;
}
}
int main(int argc, char **argv)
{
do {
printf("%s ", argv[argc-1]);
strrev_utf8(argv[argc-1]);
printf("%s\n", argv[argc-1]);
} while(--argc);
return 0;
}

$ ./strrev Räksmörgås ¦¦¦?????

Räksmörgås sågrömskäR
./strrev verrts/.
Note: The linked Jenkins issue has since been solved.
As mention in JENKINS-26133 it was not possible to get shell output as a variable. As a workaround suggested using of writ-read from temporary file. So, your example would have looked like:
sh "echo foo > result";
def output=readFile('result').trim()
echo "output=$output";

No need to close the file according to the docs if you use with:
It is good practice to use the with keyword when dealing with file objects. This has the advantage that the file is properly closed after its suite finishes, even if an exception is raised on the way. It is also much shorter than writing equivalent try-finally blocks:
>>> with open('workfile', 'r') as f:
... read_data = f.read()
>>> f.closed
True

declare @float as float(10)
declare @Decimal as decimal(10)
declare @Inetger as int
set @float =10.7
set @Decimal =10.7
set @Inetger=@Decimal
print @Inetger
in float when set value to integer print 10 but in decimal 11
no you're just using it wrong. your is_number? has an argument. you called it without the argument
you should be doing is_number?(mystring)
I have the same error after attempting to update Android Development Toolkit (ADT) plugin for Eclipse 3.5.
I haven't figured out what caused this but I re-installed (unziped Eclipse) to fix it.
Personally, I'd code it as tinyint and:
Reasons:
It will take on average 8 bytes to store text, 1 byte for tinyint. Over millions of rows, this will make a difference.
What about collation? Is "Daily" the same as "DAILY"? It takes resources to do this kind of comparison.
Finally, what if you want to add "Biweekly" or "Hourly"? This requires a schema change when you could just add new rows to a lookup table.
Why answer a 6 year old question ?
One the most fundamental concepts working with any programming language is how to navigate from one (window, form or page) to another. Also while doing this navigation the developer often wants to pass data from one (window, form or page) and display or use the data passed
While most of the answers here provide good to excellent examples how to accomplish this we thought we would kick it up a notch or two or three
We said three because we will navigate between three (window, form or page) and use the concept of static variables to pass data around the (window, form or page)
We will also include some decision making code while we navigate

it should be checked but after that wamp require restart all services
As per 'dtb' you need to use HttpStatusCode, but following 'zeldi' you need to be extra careful with code responses >= 400.
This has worked for me:
HttpWebResponse response = null;
HttpStatusCode statusCode;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException we)
{
response = (HttpWebResponse)we.Response;
}
statusCode = response.StatusCode;
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
sResponse = reader.ReadToEnd();
Console.WriteLine(sResponse);
Console.WriteLine("Response Code: " + (int)statusCode + " - " + statusCode.ToString());
If the number matches than I am checking it's occur first time or not with help of "indexOf()" if the number matches first time then print and save into in a string so, that when the next time same number matches then it's won't print because due to "indexOf()" condition will be false.

select Max(Salary) as SecondHighestSalary from Employee where Salary not in (select max(Salary) from Employee)
One small point of emphasis I'll add to all the excellent answers given previously:
Probably the biggest thing you can do to avoid using Select is to as much as possible, use named ranges (combined with meaningful variable names) in your VBA code. This point was mentioned above, but it was glossed over a bit; however, it deserves special attention.
Here are a couple of additional reasons to make liberal use of named ranges, though I am sure I could think of more.
Example:
Dim Months As Range
Dim MonthlySales As Range
Set Months = Range("Months")
' E.g, "Months" might be a named range referring to A1:A12
Set MonthlySales = Range("MonthlySales")
' E.g, "Monthly Sales" might be a named range referring to B1:B12
Dim Month As Range
For Each Month in Months
Debug.Print MonthlySales(Month.Row)
Next Month
It is pretty obvious what the named ranges Months
and MonthlySales
contain, and what the procedure is doing.
Why is this important? Partially because it is easier for other people to understand it, but even if you are the only person who will ever see or use your code, you should still use named ranges and good variable names because you will forget what you meant to do with it a year later, and you will waste 30 minutes just figuring out what your code is doing.
Consider, if the above example had been written like this:
Dim rng1 As Range
Dim rng2 As Range
Set rng1 = Range("A1:A12")
Set rng2 = Range("B1:B12")
Dim rng3 As Range
For Each rng3 in rng1
Debug.Print rng2(rng3.Row)
Next rng3
This code will work just fine at first - that is until you or a future user decides "gee wiz, I think I'm going to add a new column with the year in Column A
!", or put an expenses column between the months and sales columns, or add a header to each column. Now, your code is broken. And because you used terrible variable names, it will take you a lot more time to figure out how to fix it than it should take.
If you had used named ranges to begin with, the Months
and Sales
columns could be moved around all you like, and your code would continue working just fine.
It is true that this calculation does not make sense in a strict mathematical perspective, however if we are checking financial data it is still a useful metric. The formula could be the following:
if(lastyear>0,(thisyear/lastyear-1),((thisyear+abs(lastyear)/abs(lastyear))
let's verify the formula empirically with simple numbers:
thisyear=50 lastyear=25 growth=100%
makes sense
thisyear=25 lastyear=50 growth=-50%
makes sense
thisyear=-25 lastyear=25 growth=-200%
makes sense
thisyear=50 lastyear=-25 growth=300%
makes sense
thisyear=-50 lastyear=-25 growth=-100%
makes sense
thisyear=-25 lastyear=-50 growth=50%
makes sense
again, it might not be mathematically correct, but if you need meaningful numbers (maybe to plug them in graphs or other formulas) it's a good alternative to N/A, especially when using N/A could screw all subsequent calculations.
If you wish to use 2 subdomains to other ports, you can use Minecraft's proxy server (it means BungeeCord, Waterfall, Travertine...), and bind subdomain to specifiend in config.yml server. To do that you have to setup your servers in BungeeCord's config:
servers:
pvp:
motd: 'A Minecraft Server PVP'
address: localhost:25566
restricted: false
skyblock:
motd: 'A Minecraft Server SkyBlock'
address: localhost:25567
restricted: false
Remember! Ports must be diffrent than default Minecraft's port (it means 25565), because we will use this port to our proxy. sub1.domain.com and sub2.domain.com we have to bind to server where you have these servers. Now, we have to bind subdomains in your Bungee server:
listeners:
forced_hosts:
sub1.domain.com: pvp
sub2.domain.com: skyblock
domain.com: pvp // You can bind other domains to same servers.
Remember to change force_default_server to true, and change host to 0.0.0.0:25565 Example of BungeeCord's config.yml with some servers: https://pastebin.com/tA9ktZ6f Now you can connect to your pvp server on sub1.domain.com and connect to skyblock on sub2.domain.com. Don't worry, BungeeCord takes only 0,5GB of RAM for 500 players.
Consider that the variable is a box and the value it points to is the "thing" inside the box:
1. Pass by reference : function shares the same box and thereby the thing inside also.
2. Pass by value : function creates a new box, a replica of the old one, including a copy of whatever thing is inside it. Eg. Java - functions create a copy of the box and the thing inside it which can be: a primitive / a reference to an object. (note that the copied reference in the new box and the original both still point to the same object, here the reference IS the thing inside the box, not the object it is pointing to)
3. Pass by object-reference: the function creates a box, but it encloses the same thing the initial box was enclosing. So in Python:
a) if the thing inside said box is mutable, changes made will reflect back in the original box (eg. lists)
b) if the thing is immutable (like python strings and numeric types), then the box inside the function will hold the same thing UNTIL you try to change its value. Once changed, the thing in the function's box is a totally new thing compared to the original one. Hence id() for that box will now give the identity of the new thing it encloses.
You should not throw an ArithmeticException. Since the error is in the supplied arguments, throw an IllegalArgumentException
. As the documentation says:
Thrown to indicate that a method has been passed an illegal or inappropriate argument.
Which is exactly what is going on here.
if (divisor == 0) {
throw new IllegalArgumentException("Argument 'divisor' is 0");
}
Since maps v2 is deprecated, you are probably interested in v3 maps: https://developers.google.com/maps/documentation/javascript/markers#simple_icons
For v2 maps:
http://code.google.com/apis/maps/documentation/overlays.html#Icons_overview
You would have one set of logic do all the 'regular' pins, and another that does the 'special' pin(s) using the new marker defined.
I assume from db
that this is LINQ-to-SQL / Entity Framework / similar (not LINQ-to-Objects);
Generally, you do better with the conditional syntax ( a ? b : c) - however, I don't know if it will work with your different queries like that (after all, how would your write the TSQL?).
For a trivial example of the type of thing you can do:
select new {p.PriceID, Type = p.Price > 0 ? "debit" : "credit" };
You can do much richer things, but I really doubt you can pick the table in the conditional. You're welcome to try, of course...
laravel have own function skip
for offset
and take
for limit
. just like below example of laravel query :-
Article::where([['user_id','=',auth()->user()->id]])
->where([['title','LIKE',"%".$text_val."%"]])
->orderBy('id','DESC')
->skip(0)
->take(2)
->get();
SKINDER, your code does not use column name. Correct script is:
declare @table_name nvarchar(256)
declare @col_name nvarchar(256)
declare @Command nvarchar(1000)
set @table_name = N'users'
set @col_name = N'login'
select @Command = 'ALTER TABLE ' + @table_name + ' drop constraint ' + d.name
from sys.tables t
join sys.indexes d on d.object_id = t.object_id and d.type=2 and d.is_unique=1
join sys.index_columns ic on d.index_id=ic.index_id and ic.object_id=t.object_id
join sys.columns c on ic.column_id = c.column_id and c.object_id=t.object_id
where t.name = @table_name and c.name=@col_name
print @Command
--execute (@Command)
Python is very sensitive to indentation, with the code below I got the same error:
except IntegrityError as e:
if 'unique constraint' in e.args:
return render(request, "calender.html")
The correct indentation is:
except IntegrityError as e:
if 'unique constraint' in e.args:
return render(request, "calender.html")
You need xlutils.copy
. Try something like this:
from xlutils.copy import copy
w = copy('book1.xls')
w.get_sheet(0).write(0,0,"foo")
w.save('book2.xls')
Keep in mind you can't overwrite cells by default as noted in this question.
The code return(val);
in a function returns the value of val
to the caller of the function. Or, to quote MDN web docs, it...
...ends function execution and specifies a value to be returned to the function caller. (Source: MDN Web Docs:
return
.)
return false;
then is useful in event handlers, because this will value is used by the event-handler to determine further action. return false;
cancels events that normally take place with a handler, while return true;
lets those events to occur. To quote MDN web docs again...
The return value from the handler determines if the event is canceled. (Source: MDN Web Docs: DOM OnEvent Handlers.)
You should also use Event.preventDefault();
and Event.stopPropagation();
.
Event.preventDefault();
: To stop the default link-clicking behavior.The Event interface's preventDefault() method tells the user agent that if the event does not get explicitly handled, its default action should not be taken as it normally would be. (Source: MDN Webdocs.)
Event.stopPropagation();
: To stop the event from clicking a link within the containing parent's DOM (i.e., if two links overlapped visually in the UI).The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. (Source: MDN Webdocs.)
In this demo, we cancel an onclick
function of a link and prevent the link from being clicked with return false;
, preventDefault()
, and stopPropagation()
.
StackOverflow Demo...
document.getElementById('my-link').addEventListener('click', function(e) {
console.log('Click happened for: ' + e.target.id);
e.preventDefault();
e.stopPropagation();
return false;
});

return event;
},

SO @NotNull just is a tag...If you want to validate it, then you must use something like hibernate validator jsr 303
ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
Validator validator = validatorFactory.getValidator();

>>> print(re.escape('www.stackoverflow.com'))
www\.stackoverflow\.com
Repeating it here:
re.escape(string)
Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.
As of Python 3.7 re.escape()
was changed to escape only characters which are meaningful to regex operations.
Another option, once inside the GDB shell, before running the program, you can do
(gdb) set args file1 file2
and inspect it with:
(gdb) show args
This is fast & works for whatever length.
public static String prefixZeros(String value, int len) {
char[] t = new char[len];
int l = value.length();
int k = len-l;
for(int i=0;i<k;i++) { t[i]='0'; }
value.getChars(0, l, t, k);
return new String(t);
}
In SQL Server, it does not seem possible without using ordering in the query. This is what I have used.
SELECT *
FROM
(
SELECT TOP 5 *
FROM [MyTable]
ORDER BY Id DESC /*Primary Key*/
) AS T
ORDER BY T.Id ASC; /*Primary Key*/
The same idea as Tatu(thanks I'll need it soon in our project), but with a regular expression.
Which may be quicker for large dataset.

If ANSI_NULLS is set to "ON" and if we apply = , <> on NULL column value while writing select statement then it will not return any result.
Example
create table #tempTable (sn int, ename varchar(50))
insert into #tempTable
values (1, 'Manoj'), (2, 'Pankaj'), (3, NULL), (4, 'Lokesh'), (5, 'Gopal')
SET ANSI_NULLS ON
select * from #tempTable where ename is NULL -- (1 row(s) affected)
select * from #tempTable where ename = NULL -- (0 row(s) affected)
select * from #tempTable where ename is not NULL -- (4 row(s) affected)
select * from #tempTable where ename <> NULL -- (0 row(s) affected)
SET ANSI_NULLS OFF
select * from #tempTable where ename is NULL -- (1 row(s) affected)
select * from #tempTable where ename = NULL -- (1 row(s) affected)
select * from #tempTable where ename is not NULL -- (4 row(s) affected)
select * from #tempTable where ename <> NULL -- (4 row(s) affected)
I got this issue when I used an ajax call to retrieve data from the database. When the controller returned the array it converted it to a boolean. The problem was that I had "invalid characters" like ú (u with accent).
This is powerful and tested unset($gradearray);//re-set the array
It seems to me all existing answers on this page are wrong, including the one marked as correct. That stems from the fact that the question is ambiguously worded.
Summary: If you want to execute the command "exactly once for each line of input," passing the entire line (without newline) to the command as a single argument, then this is the best UNIX-compatible way to do it:
... | tr '\n' '\0' | xargs -0 -n1 ...
If you are using GNU xargs
and don't need to be compatible with all other UNIX's (FreeBSD, Mac OS X, etc.) then you can use the GNU-specific option -d
:
... | xargs -d\\n -n1 ...
Now for the long explanation…
There are two issues to take into account when using xargs:
To test xargs' behavior, we need an utility that shows how many times it's being executed and with how many arguments. I don't know if there is a standard utility to do that, but we can code it quite easily in bash:
#!/bin/bash
echo -n "-> "; for a in "$@"; do echo -n "\"$a\" "; done; echo
Assuming you save it as show
in your current directory and make it executable, here is how it works:
$ ./show one two 'three and four'
-> "one" "two" "three and four"
Now, if the original question is really about point 2. above (as I think it is, after reading it a few times over) and it is to be read like this (changes in bold):
How can I make xargs execute the command exactly once for each argument of input given? Its default behavior is to chunk the input into arguments and execute the command as few times as possible, passing multiple arguments to each instance.
then the answer is -n 1
.
Let's compare xargs' default behavior, which splits the input around whitespace and calls the command as few times as possible:
$ echo one two 'three and four' | xargs ./show
-> "one" "two" "three" "and" "four"
and its behavior with -n 1
:
$ echo one two 'three and four' | xargs -n 1 ./show
-> "one"
-> "two"
-> "three"
-> "and"
-> "four"
If, on the other hand, the original question was about point 1. input splitting and it was to be read like this (many people coming here seem to think that's the case, or are confusing the two issues):
How can I make xargs execute the command with exactly one argument for each line of input given? Its default behavior is to chunk the lines around whitespace.
then the answer is more subtle.
One would think that -L 1
could be of help, but it turns out it doesn't change argument parsing. It only executes the command once for each input line, with as many arguments as were there on that input line:
$ echo $'one\ntwo\nthree and four' | xargs -L 1 ./show
-> "one"
-> "two"
-> "three" "and" "four"
Not only that, but if a line ends with whitespace, it is appended to the next:
$ echo $'one \ntwo\nthree and four' | xargs -L 1 ./show
-> "one" "two"
-> "three" "and" "four"
Clearly, -L
is not about changing the way xargs splits the input into arguments.
The only argument that does so in a cross-platform fashion (excluding GNU extensions) is -0
, which splits the input around NUL bytes.
Then, it's just a matter of translating newlines to NUL with the help of tr
:
$ echo $'one \ntwo\nthree and four' | tr '\n' '\0' | xargs -0 ./show
-> "one " "two" "three and four"
Now the argument parsing looks all right, including the trailing whitespace.
Finally, if you combine this technique with -n 1
, you get exactly one command execution per input line, whatever input you have, which may be yet another way to look at the original question (possibly the most intuitive, given the title):
$ echo $'one \ntwo\nthree and four' | tr '\n' '\0' | xargs -0 -n1 ./show
-> "one "
-> "two"
-> "three and four"
As mentioned above, if you are using GNU xargs
you can replace the tr
with the GNU-specific option -d
:
$ echo $'one \ntwo\nthree and four' | xargs -d\\n -n1 ./show
-> "one "
-> "two"
-> "three and four"
The following is my solutions which works ( 5 steps )
Step1: Add an observer to catch which UITEXTFIELD or UITEXTVIEW ShoudBeginEditing ( where object is inited or ViewDidLoad.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(updateActiveField:)
name:@"UPDATE_ACTIVE_FIELD" object:nil];
Step2: Post a notification when ..ShouldBeginEditing with OBJECT of UITEXTFIELD or UITEXTVIEW
-(BOOL)textViewShouldBeginEditing:(UITextView *)textView {
[[NSNotificationCenter defaultCenter] postNotificationName:@"UPDATE_ACTIVE_FIELD"
object:textView];
return YES;
}
Step3: The method that (Step1 calles ) assigns the current UITEXTFIELD or UITEXTVIEW
-(void) updateActiveField: (id) sender {
activeField = [sender object];
}
Step4: Add Keyboard observer UIKeyboardWillShowNotification ( same place as Step1 )
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWasShown:)
name:UIKeyboardDidShowNotification object:nil];
and method:
// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
_currentEdgeInsets = self.layoutPanel.contentInset; // store current insets to restore them later
self.layoutPanel.contentInset = contentInsets;
self.layoutPanel.scrollIndicatorInsets = contentInsets;
// If active text field is hidden by keyboard, scroll it so it's visible
CGRect aRect = self.view.frame;
aRect.size.height -= kbSize.height;
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
CGPoint p = [activeField convertPoint:activeField.bounds.origin toView:window];
if (!CGRectContainsPoint(aRect, p) ) {
CGPoint scrollPoint = CGPointMake(0.0, activeField.frame.origin.y +kbSize.height);
[self.layoutPanel setContentOffset:scrollPoint animated:YES];
self.layoutPanel.scrollEnabled = NO;
}
}
Step5: Add Keyboard observer UIKeyboardWillHideNotification ( same place as step 1 )
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillBeHidden:)
name:UIKeyboardWillHideNotification object:nil];
and method:
// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
self.layoutPanel.contentInset = _currentEdgeInsets;
self.layoutPanel.scrollIndicatorInsets = _currentEdgeInsets;
self.layoutPanel.scrollEnabled = YES;
}
Remember to remove observers!
You can use either this in the onCreate() method of the activity
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
or paste this code in the Activity tags in AndroidManifest.xml
android:windowSoftInputMode="stateVisible"
EDIT
As pointed out by @Kwame , the below code does validate the url even if the
.com
or.co
etc are not present.also pointed out by @Blaise, URLs like https://www.google is a valid URL and you need to do a DNS check for checking if it resolves or not, separately.
This is simple and works:
So min_attr
contains the basic set of strings that needs to be present to define the validity of a URL,
i.e http://
part and google.com
part.
urlparse.scheme
stores http://
and
urlparse.netloc
store the domain name google.com
from urlparse import urlparse
def url_check(url):
min_attr = ('scheme' , 'netloc')
try:
result = urlparse(url)
if all([result.scheme, result.netloc]):
return True
else:
return False
except:
return False
all()
returns true if all the variables inside it return true.
So if result.scheme
and result.netloc
is present i.e. has some value then the URL is valid and hence returns True
.

In short:
static_cast<>()
gives you a compile time checking ability, C-Style
cast doesn't.static_cast<>()
is more readable and can be spotted easily
anywhere inside a C++ source code, C_Style cast is'nt.More Explanation:
The static cast performs conversions between compatible types. It is similar to the C-style cast, but is more restrictive. For example, the C-style cast would allow an integer pointer to point to a char.
char c = 10; // 1 byte
int *p = (int*)&c; // 4 bytes
Since this results in a 4-byte pointer ( a pointer to 4-byte datatype) pointing to 1 byte of allocated memory, writing to this pointer will either cause a run-time error or will overwrite some adjacent memory.
*p = 5; // run-time error: stack corruption
In contrast to the C-style cast, the static cast will allow the compiler to check that the pointer and pointee data types are compatible, which allows the programmer to catch this incorrect pointer assignment during compilation.
int *q = static_cast<int*>(&c); // compile-time error

Your code works for me. Here is my test case:
mysql> CREATE TABLE carmake (country ENUM('Canada', 'United States'));
Query OK, 0 rows affected (0.00 sec)
mysql> SHOW CREATE TABLE carmake;
+---------+-------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+---------+-------------------------------------------------------------------------------------------------------------------------+
| carmake | CREATE TABLE `carmake` (
`country` enum('Canada','United States') default NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |
+---------+-------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
mysql> ALTER TABLE carmake CHANGE country country ENUM('Sweden','Malaysia');
Query OK, 0 rows affected (0.53 sec)
Records: 0 Duplicates: 0 Warnings: 0
mysql> SHOW CREATE TABLE carmake;
+---------+--------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+---------+--------------------------------------------------------------------------------------------------------------------+
| carmake | CREATE TABLE `carmake` (
`country` enum('Sweden','Malaysia') default NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |
+---------+--------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
What error are you seeing?
FWIW this would also work:
ALTER TABLE carmake MODIFY COLUMN country ENUM('Sweden','Malaysia');
I would actually recommend a country table rather than enum column. You may have hundreds of countries which would make for a rather large and awkward enum.
EDIT: Now that I can see your error message:
ERROR 1265 (01000): Data truncated for column 'country' at row 1.
I suspect you have some values in your country column that do not appear in your ENUM
. What is the output of the following command?
SELECT DISTINCT country FROM carmake;
ANOTHER EDIT: What is the output of the following command?
SHOW VARIABLES LIKE 'sql_mode';
Is it STRICT_TRANS_TABLES
or STRICT_ALL_TABLES
? That could lead to an error, rather than the usual warning MySQL would give you in this situation.
YET ANOTHER EDIT: Ok, I now see that you definitely have values in the table that are not in the new ENUM
. The new ENUM
definition only allows 'Sweden'
and 'Malaysia'
. The table has 'USA'
, 'India'
and several others.
LAST EDIT (MAYBE): I think you're trying to do this:
ALTER TABLE carmake CHANGE country country ENUM('Italy', 'Germany', 'England', 'USA', 'France', 'South Korea', 'Australia', 'Spain', 'Czech Republic', 'Sweden', 'Malaysia') DEFAULT NULL;
If you have a list view you can do this:
Define a select list:
@{
var Acciones = new SelectList(new[]
{
new SelectListItem { Text = "Modificar", Value =
Url.Action("Edit", "Countries")},
new SelectListItem { Text = "Detallar", Value =
Url.Action("Details", "Countries") },
new SelectListItem { Text = "Eliminar", Value =
Url.Action("Delete", "Countries") },
}, "Value", "Text");
}
Use the defined SelectList, creating a diferent id for each record (remember that id of each element must be unique in a view), and finally call a javascript function for onchange event (include parameters in example url and record key):
@Html.DropDownList("ddAcciones", Acciones, "Acciones", new { id =
item.CountryID, @onchange = "RealizarAccion(this.value ,id)" })
onchange function can be something as:
@section Scripts {
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<script type="text/javascript">
function RealizarAccion(accion, country)
{
var url = accion + '/' + country;
if (url != null && url != '') {
window.location.href = url ;
}
}
</script>
@Scripts.Render("~/bundles/jqueryval")
}
It depends which version of C# you're using, from version 3.0 onwards you can use...
List<string> nameslist = new List<string> { "one", "two", "three" };
The easiest way to match both
^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$
and
^[0-9]{3}-[0-9]{3}-[0-9]{4}$
is to use alternation ((...|...)
): specify them as two mostly-separate options:
^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$
By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234
, not (123)123-1234
. So you might want to write:
^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$
(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)
After browsing search engines for a few hours I came across a site with a great ERD example here: http://www.exploredatabase.com/2016/07/description-about-weak-entity-sets-in-DBMS.html
I've recreated the ERD. Unfortunately they did not specify the primary key of the weak entity.
If the building could only have one and only one apartment, then it seems the partial discriminator room number would not be created (i.e. discarded).
It echoes the data used in your request for any of these types:
If you have to check it out manually you can do int a = s.charAt(0)
If the value of a is between 65 to 90 it is upper case.
As the others have stated, the difference is that <b>
and <i>
hardcode font styles, whereas <strong>
and <em>
dictate semantic meaning, with the font style (or speaking browser intonation, or what-have-you) to be determined at the time the text is rendered (or spoken).
You can think of this as a difference between a “physical” font style and a “logical” style, if you will. At some later time, you may wish to change the way <strong>
and <em>
text are displayed, say, by altering properties in a style sheet to add color and size changes, or even to use different font faces entirely. If you've used “logical” markup instead of hardcoded “physical” markup, then you can simply change the display properties in one place each in your style sheet, and then all of the pages that reference that style sheet get changed automatically, without ever having to edit them.
Pretty slick, huh?
This is also the rationale behind defining sub-styles (referenced using the style=
property in text tags) for paragraphs, table cells, header text, captions, etc., and using <div>
tags. You can define physical representation for your logical styles in the style sheet, and the changes are automatically reflected in the web pages that reference that style sheet. Want a different representation for source code? Redefine the font, size, weight, spacing, etc. for your "code" style.
If you use XHTML, you can even define your own semantic tags, and your style sheet would do the conversions to physical font styles and layouts for you.
First of all, parent-child scope relation does matter. You have two possibilities to emit some event:
$broadcast
-- dispatches the event downwards to all child scopes,$emit
-- dispatches the event upwards through the scope hierarchy.I don't know anything about your controllers (scopes) relation, but there are several options:
If scope of firstCtrl
is parent of the secondCtrl
scope, your code should
work by replacing $emit
by $broadcast
in firstCtrl
:
function firstCtrl($scope)
{
$scope.$broadcast('someEvent', [1,2,3]);
}
function secondCtrl($scope)
{
$scope.$on('someEvent', function(event, mass) { console.log(mass); });
}
In case there is no parent-child relation between your scopes you
can inject $rootScope
into the controller and broadcast the event
to all child scopes (i.e. also secondCtrl
).
function firstCtrl($rootScope)
{
$rootScope.$broadcast('someEvent', [1,2,3]);
}
Finally, when you need to dispatch the event from child controller
to scopes upwards you can use $scope.$emit
. If scope of firstCtrl
is parent of the secondCtrl
scope:
function firstCtrl($scope)
{
$scope.$on('someEvent', function(event, data) { console.log(data); });
}
function secondCtrl($scope)
{
$scope.$emit('someEvent', [1,2,3]);
}
Static variable doesn't link with object of the class. It can be accessed using classname. All object of the class will share static variable.
By making function as static, It will restrict the access of that function within that file.
Indeed, if you sorted out the iterator then buffering could now be your problem. You could tell the python in the sub-process not to buffer its output.
proc = subprocess.Popen(['python','fake_utility.py'],stdout=subprocess.PIPE)
becomes
proc = subprocess.Popen(['python','-u', 'fake_utility.py'],stdout=subprocess.PIPE)
I have needed this when calling python from within python.
Something along these lines worked for me. Starting with a bit of code taken from Joe, this method modifies the window width to automatically fit a legend to the right of the figure.
import matplotlib.pyplot as plt
import numpy as np
plt.ion()
x = np.arange(10)
fig = plt.figure()
ax = plt.subplot(111)
for i in xrange(5):
ax.plot(x, i * x, label='$y = %ix$'%i)
# Put a legend to the right of the current axis
leg = ax.legend(loc='center left', bbox_to_anchor=(1, 0.5))
plt.draw()
# Get the ax dimensions.
box = ax.get_position()
xlocs = (box.x0,box.x1)
ylocs = (box.y0,box.y1)
# Get the figure size in inches and the dpi.
w, h = fig.get_size_inches()
dpi = fig.get_dpi()
# Get the legend size, calculate new window width and change the figure size.
legWidth = leg.get_window_extent().width
winWidthNew = w*dpi+legWidth
fig.set_size_inches(winWidthNew/dpi,h)
# Adjust the window size to fit the figure.
mgr = plt.get_current_fig_manager()
mgr.window.wm_geometry("%ix%i"%(winWidthNew,mgr.window.winfo_height()))
# Rescale the ax to keep its original size.
factor = w*dpi/winWidthNew
x0 = xlocs[0]*factor
x1 = xlocs[1]*factor
width = box.width*factor
ax.set_position([x0,ylocs[0],x1-x0,ylocs[1]-ylocs[0]])
plt.draw()
To create a test case template:
"New" -> "JUnit Test Case" -> Select "Class under test" -> Select "Available methods". I think the wizard is quite easy for you.
It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.
<input id="myFileInput" type="file" accept="image/*;capture=camera">
var myInput = document.getElementById('myFileInput');
function sendPic() {
var file = myInput.files[0];
// Send file here either by adding it to a `FormData` object
// and sending that via XHR, or by simply passing the file into
// the `send` method of an XHR instance.
}
myInput.addEventListener('change', sendPic, false);
Pass Today as value as mentioned below in $viewQuery property :

$viewTitle = "Program Events" #Title property
#Add the column names from the ViewField property to a string collection
$viewFields = New-Object System.Collections.Specialized.StringCollection
$viewFields.Add("Event Date") > $null
$viewFields.Add("Title") > $null
#Query property
$viewQuery = "<Where><Geq><FieldRef Name='EventDate' /><Value IncludeTimeValue='TRUE' Type='DateTime'><Today/></Value></Geq></Where><OrderBy><FieldRef Name='EventDate' Ascending='True' /></OrderBy>"
#RowLimit property
$viewRowLimit = 30
#Paged property
$viewPaged = $true
#DefaultView property
$viewDefaultView = $false
#Create the view in the destination list
$newview = $list.Views.Add($viewTitle, $viewFields, $viewQuery, $viewRowLimit, $viewPaged, $viewDefaultView)
Write-Host ("View '" + $newview.Title + "' created in list '" + $list.Title + "' on site " + $web.Url)

You have to be sure to use UIPickerViewDataSource and UIPickerViewDelegate protocols or it will throw an AppDelegate error as of swift 3
Also please take note of the change in syntax:
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int
is now:
public func numberOfComponents(in pickerView: UIPickerView) -> Int
The following below worked for me.
import UIkit
class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
@IBOutlet weak var textBox: UITextField!
@IBOutlet weak var dropDown: UIPickerView!
var list = ["1", "2", "3"]
public func numberOfComponents(in pickerView: UIPickerView) -> Int{
return 1
}
public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{
return list.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
self.view.endEditing(true)
return list[row]
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
self.textBox.text = self.list[row]
self.dropDown.isHidden = true
}
func textFieldDidBeginEditing(_ textField: UITextField) {
if textField == self.textBox {
self.dropDown.isHidden = false
//if you don't want the users to se the keyboard type:
textField.endEditing(true)
}
}
}
I've used node-cron and agenda.
node-cron is a very simple library, which provide very basic and easy to understand api like crontab. It doesn't need any config and just works.
var cronJob = require('cron').CronJob;
var myJob = new cronJob('00 30 11 * * 1-5', function(){...});
myJob.start();
agenda is very powerful and fit for much more complex services. Think about ifttt, you have to run millions of tasks. agenda would be the best choice.
Note: You need Mongodb to use Agenda
var Agenda = require("Agenda");
var agenda = new Agenda({db: { address: 'localhost:27017/agenda-example'}});
agenda.every('*/3 * * * *', 'delete old users');
agenda.start();
This was an old question, but existing answers ignore the serious issue of throwing away any custom attributes when you regenerate the model. I am adding a more detailed answer to cover the current options available.
[DisplayName("Name goes here")]
attribute to the data model class. The downside is that this is thrown away whenever you regenerate the data models.Html.LabelFor
. e.g. @Html.LabelFor(model => model.SomekingStatus, "My New Label", new { @class = "control-label"})
Reference: https://msdn.microsoft.com/en-us/library/system.web.mvc.html.labelextensions.labelfor(v=vs.118).aspx The downside to this is that you must repeat the label in every view.Microsoft allows for decorating properties on an Entity Framework class, without modifying the existing class! This by having meta-data classes that attach to your database classes (effectively a sideways extension of your EF class). This allow attributes to be added to the associated class and not to the class itself so the changes are not lost when you regenerate the data models.
For example, if your data class is MyModel
with a SomekingStatus
property, you could do it like this:
First declare a partial class of the same name (and using the same namespace), which allows you to add a class attribute without being overridden:
[MetadataType(typeof(MyModelMetaData))]
public partial class MyModel
{
}
All generated data model classes are partial classes, which allow you to add extra properties and methods by simply creating more classes of the same name (this is very handy and I often use it e.g. to provide formatted string versions of other field types in the model).
Step 2: add a metatadata class referenced by your new partial class:
public class MyModelMetaData
{
// Apply DisplayNameAttribute (or any other attributes)
[DisplayName("My New Label")]
public string SomekingStatus;
}
[required]
etc) so you may need to duplicate those in the Meta-data class.Only for using as a value:
x = 3 if a==2 else 0
or
return 3 if a==2 else 0
Every time I have run into this issue was when attempting to attach a database that is in a different directory from the default database directory that is setup in SQL server.
I would highly recommend that instead of jacking with permissions on various directories and accounts that you simply move your data file into the directory that sql server expects to find it.

It's not Twitter bootstrap specific, it is a normal HTML5 component and you can specify the range with the min
and max
attributes (in your case only the first attribute). For example:
<div> _x000D_
<input type="number" id="replyNumber" min="0" data-bind="value:replyNumber" />_x000D_
</div>
_x000D_
I'm not sure if only integers are allowed by default in the control or not, but else you can specify the step
attribute:
<div> _x000D_
<input type="number" id="replyNumber" min="0" step="1" data-bind="value:replyNumber" />_x000D_
</div>
_x000D_
Now only numbers higher (and equal to) zero can be used and there is a step of 1, which means the values are 0, 1, 2, 3, 4, ... .
BE AWARE: Not all browsers support the HTML5 features, so it's recommended to have some kind of JavaScript fallback (and in your back-end too) if you really want to use the constraints.
For a list of browsers that support it, you can look at caniuse.com.
pep8 was recently added to PyPi.
It is now super easy to check your code against pep8.

Angular6 using the renderer2 without any variables and a clean template:
template:
<div (click)="toggleClass($event,'testClass')"></div>
in ts:
toggleClass(event: any, class: string) {
const hasClass = event.target.classList.contains(class);
if(hasClass) {
this.renderer.removeClass(event.target, class);
} else {
this.renderer.addClass(event.target, class);
}
}
One could put this in a directive too ;)
Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:
The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.
What about:
tail -n +347340107 filename | head -n 100
I didn't test it, but I think that would work.
What about
Game.status[0][0] or Game.status[0]["0"] ?
Does one of these work?
PS: What you have in your question is a Javascript Object, not JSON. JSON is the 'string' version of a Javascript Object.
This is indeed rather odd.
If aSourceDictionary
were a dictionary, I don't believe it is possible for your code to fail in the manner you describe.
This leads to two hypotheses:
The code you're actually running is not identical to the code in your question (perhaps an earlier or later version?)
aSourceDictionary
is in fact not a dictionary, but is some other structure (for example, a list).
If you have been making commits on your main branch while you coded, but you now want to move those commits to a different branch, this is a quick way:
Copy your current history onto a new branch, bringing along any uncommitted changes too:
git checkout -b <new-feature-branch>
Now force the original "messy" branch to roll back: (without switching to it)
git branch -f <previous-branch> <earlier-commit-id>
For example:
git branch -f master origin/master
or if you had made 4 commits:
git branch -f master HEAD~4
Warning: git branch -f master origin/master
will reset the tracking information for that branch. So if you have configured your master
branch to push to somewhere other than origin/master
then that configuration will be lost.
Warning: If you rebase after branching, there is a danger that some commits may be lost, which is described here. The only way to avoid that is to create a new history using cherry-pick. That link describes the safest fool-proof method, although less convenient. (If you have uncommitted changes, you may need to git stash
at the start and git stash pop
at the end.)
Laravel now supports this feature out-of-the-box! (I believe since 5.5 or earlier).
Add a __construct()
method to your Controller
as shown below:
public function __construct()
{
$this->middleware('auth');
}
After login, your users will then be redirected to the page they intended to visit initially.
You can also add Laravel's email verification feature as required by your application logic:
public function __construct()
{
$this->middleware(['auth', 'verified']);
}
The documentation contains a very brief example:
It's also possible to choose which controller's methods the middleware applies to by using except
or only
options.
Example with except
:
public function __construct()
{
$this->middleware('auth', ['except' => ['index', 'show']]);
}
Example with only
:
public function __construct()
{
$this->middleware('auth', ['only' => ['index', 'show']]);
}
More information about except
and only
middleware options:
If all of the matrices are going to be the same size (i.e. 500x800), then you can just make a 3D array:
nUnknown; % The number of unknown arrays
myArray = zeros(500,800,nUnknown);
To access one array, you would use the following syntax:
subMatrix = myArray(:,:,3); % Gets the third matrix
You can add more matrices to myArray in a couple of ways:
myArray = cat(3,myArray,zeros(500,800));
% OR
myArray(:,:,nUnknown+1) = zeros(500,800);
If each matrix is not going to be the same size, you would need to use cell arrays like Hosam suggested.
EDIT: I missed the part about running out of memory. I'm guessing your nUnknown is fairly large. You may have to switch the data type of the matrices (single or even a uintXX type if you are using integers). You can do this in the call to zeros:
myArray = zeros(500,800,nUnknown,'single');
With Spring Boot
its not necessary to have any config file like persistence.xml
. You can configure with annotations
Just configure your DB config for JPA in the
spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@DB...
spring.datasource.username=username
spring.datasource.password=pass
spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true
Then you can use CrudRepository
provided by Spring where you have standard CRUD
transaction methods. There you can also implement your own SQL's
like JPQL
.
@Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}
And if you still need to use the Entity Manager
you can create another class.
public class ObjectRepositoryImpl implements ObjectCustomMethods{
@PersistenceContext
private EntityManager em;
}
This should be in your pom.xml

Hi the getOptimalPreview() that is here didn't worked for me so I want to share my version:
private Camera.Size getOptimalPreviewSize(List<Camera.Size> sizes, int w, int h) {
if (sizes==null) return null;
Camera.Size optimalSize = null;
double ratio = (double)h/w;
double minDiff = Double.MAX_VALUE;
double newDiff;
for (Camera.Size size : sizes) {
newDiff = Math.abs((double)size.width/size.height - ratio);
if (newDiff < minDiff) {
optimalSize = size;
minDiff = newDiff;
}
}
return optimalSize;
}
Here is how to build a function that returns a result set that can be queried as if it were a table:
SQL> create type emp_obj is object (empno number, ename varchar2(10));
2 /
Type created.
SQL> create type emp_tab is table of emp_obj;
2 /
Type created.
SQL> create or replace function all_emps return emp_tab
2 is
3 l_emp_tab emp_tab := emp_tab();
4 n integer := 0;
5 begin
6 for r in (select empno, ename from emp)
7 loop
8 l_emp_tab.extend;
9 n := n + 1;
10 l_emp_tab(n) := emp_obj(r.empno, r.ename);
11 end loop;
12 return l_emp_tab;
13 end;
14 /
Function created.
SQL> select * from table (all_emps);

You can use ExecutorService.invokeAll
method, It will execute all task and wait till all threads finished their task.
Here is complete javadoc
You can also user overloaded version of this method to specify the timeout.
Here is sample code with ExecutorService.invokeAll
public class Test {
public static void main(String[] args) throws InterruptedException, ExecutionException {
ExecutorService service = Executors.newFixedThreadPool(3);
List<Callable<String>> taskList = new ArrayList<>();
taskList.add(new Task1());
taskList.add(new Task2());
List<Future<String>> results = service.invokeAll(taskList);
for (Future<String> f : results) {
System.out.println(f.get());
}
}
}
class Task1 implements Callable<String> {
@Override
public String call() throws Exception {
try {
Thread.sleep(2000);
return "Task 1 done";
} catch (Exception e) {
e.printStackTrace();
return " error in task1";
}
}
}
class Task2 implements Callable<String> {
@Override
public String call() throws Exception {
try {
Thread.sleep(3000);
return "Task 2 done";
} catch (Exception e) {
e.printStackTrace();
return " error in task2";
}
}
}
The problem is that you forgot to import os. Add this line of code:
import os
And everything should be fine. Hope this helps!
If you are using a version of enthought python (EPD) you might want to go directly to your site-packages and reinstall numpy. Then try to install pandas with pip. You will have to modify your installation prefix for that.
If the problem persists (as it did with me) try downloading pandas tar ball, unpack it in your site packages and run setup.py install
from your pandas directory.
If you got your dependencies right you can import pandas and check it imports smoothly.
This is not as complicated as some of the other answers make it.
Just use auto layout to add constraints to pin the left and top sides of the label.
After that it will automatically resize.
No need to set sizeToFit
when using auto layout. My complete code for the example project is here:
import UIKit
class ViewController: UIViewController {
@IBOutlet weak var myLabel: UILabel!
@IBAction func changeTextButtonTapped(sender: UIButton) {
myLabel.text = "my name is really long i want it to fit in this box"
}
}
myLabel.preferredMaxLayoutWidth = 150 // or whatever
in code. (I also pinned my button to the bottom of the label so that it would move down when the label height increased.)UITableViewCell
then see this answer.Here is the snippet of getting the attribute value of "lang" with XPath and VTD-XML.
import com.ximpleware.*;
public class getAttrVal {
public static void main(String s[]) throws VTDException{
VTDGen vg = new VTDGen();
if (!vg.parseFile("input.xml", false)){
return ;
}
VTDNav vn = vg.getNav();
AutoPilot ap = new AutoPilot(vn);
ap.selectXPath("/bookstore/book/title/@lang");
System.out.println(" lang's value is ===>"+ap.evalXPathToString());
}
}
if re.match(regex, content):
blah..
You could also use re.search
depending on how you want it to match.
Install the 2007 version, it seems that if you install the version opposite to the version of Office you are using you can make it work.

You can call $setUnion
on a single array, which also filters dupes:
{ $project: {Package: 1, deps: {'$setUnion': '$deps.Package'}}}
One can also bind a function with ng-change
event listener, if they need to run a bit more complex logic.
<div ng-app="myApp" ng-controller="myCtrl">
<input type='text' ng-model='name' ng-change='change()'>
<br/> <span>changed {{counter}} times </span>
</div>
...
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.name = 'Australia';
$scope.counter = 0;
$scope.change = function() {
$scope.counter++;
};
});
It's an X(HT)ML thing. When you use symbols like <
and >
within the JavaScript, e.g. for comparing two integers, this would have to be parsed like XML, thus they would mark as a beginning or end of a tag.
The CDATA means that the following lines (everything up unto the ]]>
is not XML and thus should not be parsed that way.
Instead of comparing the dates directly, compare the getTime() value of the date. The getTime() function returns the number of milliseconds since Jan 1, 1970 as an integer-- should be trivial to determine if one integer falls between two other integers.
Something like
if((check.getTime() <= to.getTime() && check.getTime() >= from.getTime())) alert("date contained");
Don't delete them!!! Until..........
Find a version on your git, svn or copy folder that works.
Delete them and then recover all .pyc.
That's work for me.
flask.Flask.run
accepts additional keyword arguments (**options
) that it forwards to werkzeug.serving.run_simple
- two of those arguments are threaded
(a boolean) and processes
(which you can set to a number greater than one to have werkzeug spawn more than one process to handle requests).
threaded
defaults to True
as of Flask 1.0, so for the latest versions of Flask, the default development server will be able to serve multiple clients simultaneously by default. For older versions of Flask, you can explicitly pass threaded=True
to enable this behaviour.
For example, you can do
if __name__ == '__main__':
app.run(threaded=True)
to handle multiple clients using threads in a way compatible with old Flask versions, or
if __name__ == '__main__':
app.run(threaded=False, processes=3)
to tell Werkzeug to spawn three processes to handle incoming requests, or just
if __name__ == '__main__':
app.run()
to handle multiple clients using threads if you know that you will be using Flask 1.0 or later.
That being said, Werkzeug's serving.run_simple
wraps the standard library's wsgiref
package - and that package contains a reference implementation of WSGI, not a production-ready web server. If you are going to use Flask in production (assuming that "production" is not a low-traffic internal application with no more than 10 concurrent users) make sure to stand it up behind a real web server (see the section of Flask's docs entitled Deployment Options for some suggested methods).
Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount()
in a React class.
For you edit, you may want to try something like this:
class Component extends React.Component {
constructor(props) {
super(props);
this.onAddBucket = this.onAddBucket.bind(this);
}
componentWillMount() {
this.setState({
buckets: {},
})
}
componentDidMount() {
this.onAddBucket();
}
onAddBucket() {
let self = this;
let getToken = localStorage.getItem('myToken');
var apiBaseUrl = "...";
let input = {
"name" : this.state.fields["bucket_name"]
}
axios.defaults.headers.common['Authorization'] = getToken;
axios.post(apiBaseUrl+'...',input)
.then(function (response) {
if (response.data.status == 200) {
this.setState({
buckets: this.state.buckets.concat(response.data.buckets),
});
} else {
alert(response.data.message);
}
})
.catch(function (error) {
console.log(error);
});
}
render() {
return (
{this.state.bucket}
);
}
}
Start the console (Windows XP), Run -> type cmd, and move to the platform-tools folder of SDK directory.
In case anyone wondering how to run cmd
in platform-tools
folder of SDK directory, if you are running a new enough version of Windows, follow the steps:
platform-tools
through Windows Explorer.shift
right click and you will find the option "Open Command window here".Hope it helps
The main difference between that and cron is that an exception will kill the daemon for good. You might want to wrap with an exception catcher and logger.

sp_help table_name
(or sp_columns table_name

Yes, all you need to do is call finish() in any Activity you would like to close.
You can't call a Javascript function from the CodeBehind, because the CodeBehind file contains the code that executes server side on the web server. Javascript code executes in the web browser on the client side.
If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.
The original code is from Sabry Suleiman.
Made it a bit prettier:
function is_session_started() {
if ( php_sapi_name() === 'cli' )
return false;
return version_compare( phpversion(), '5.4.0', '>=' )
? session_status() === PHP_SESSION_ACTIVE
: session_id() !== '';
}
First condition checks the Server API in use. If Command Line Interface is used, the function returns false.
Then we return the boolean result depending on the PHP version in use.
In ancient history you simply needed to check session_id()
. If it's an empty string, then session is not started. Otherwise it is.
Since 5.4 to at least the current 8.0 the norm is to check session_status()
. If it's not PHP_SESSION_ACTIVE
, then either the session isn't started yet (PHP_SESSION_NONE
) or sessions are not available altogether (PHP_SESSION_DISABLED
).
Link your custom.css file as the last entry below the bootstrap.css. Custom.css style definitions will override bootstrap.css

I see in your code that you are trying to pass an ARRAY to POST action. In that case follow below working code -
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
function submitForm() {
var roles = ["role1", "role2", "role3"];
jQuery.ajax({
type: "POST",
url: "@Url.Action("AddUser")",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(roles),
success: function (data) { alert(data); },
failure: function (errMsg) {
alert(errMsg);
}
});
}
</script>
<input type="button" value="Click" onclick="submitForm()"/>
And the controller action is going to be -
public ActionResult AddUser(List<String> Roles)
{
return null;
}
Then when you click on the button -
Check this link.. It will definitely solve your problem.. There are plenty of solutions to make cross domain GET Ajax calls BUT POST REQUEST FOR CROSS DOMAIN IS SOLVED HERE. It took me 3 days to figure it out.

If you are trying to get extra data in fragments then you can try using:
Place data using:
Bundle args = new Bundle();
args.putInt(DummySectionFragment.ARG_SECTION_NUMBER);
Get data using:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
getArguments().getInt(ARG_SECTION_NUMBER);
getArguments().getString(ARG_SECTION_STRING);
getArguments().getBoolean(ARG_SECTION_BOOL);
getArguments().getChar(ARG_SECTION_CHAR);
getArguments().getByte(ARG_SECTION_DATA);
}
The code you've already tried:
document.getElementById("gift-close").click();
...should work as long as the element actually exists in the DOM at the time you run it. Some possible ways to ensure that include:
onload
handler for the window. http://jsfiddle.net/LKNYg/So:
$(document).ready(function() {
document.getElementById("gift-close").click();
// OR
$("#gift-close")[0].click();
});

It's wonderful to finally have this solved without using a hack.
an additional note:
if you have already added a remote ($git remote add origin ... ) and need to change that particular remote then do a remote remove first ($ git remote rm origin), before re-adding the new and improved repo URL (where "origin" was the name for the remote repo).
so to use the original example :
$ git remote add origin https://github.com/WEMP/project-slideshow.git
$ git remote rm origin
$ git remote add origin https://[email protected]/WEMP/project-slideshow.git
you mentioned "entire line" , so i assumed mystring is the entire line.
if "token" in mystring:
print(mystring)
however if you want to just get "token qwerty",
>>> mystring="""
... qwertyuiop
... asdfghjkl
...
... zxcvbnm
... token qwerty
...
... asdfghjklñ
... """
>>> for item in mystring.split("\n"):
... if "token" in item:
... print (item.strip())
...
token qwerty
Try this,
int dialogButton = JOptionPane.YES_NO_OPTION;
int dialogResult = JOptionPane.showConfirmDialog(this, "Your Message", "Title on Box", dialogButton);
if(dialogResult == 0) {
System.out.println("Yes option");
} else {
System.out.println("No Option");
}
If the schema of id is not of type ObjectId you cannot operate with function : findbyId()

This is like FlappySock's answer, but I added a callback to it because I didn't like the layout and how the Boolean was getting returned. In the comments of that answer from Nick Miller:
In my experience, if the end point can be reached, but there is no server on the endpoint able to receive the connection, then AsyncWaitHandle.WaitOne will be signaled, but the socket will remain unconnected
So to me, it seems relying on what is returned can be dangerous - I prefer to use socket.Connected
. I set a nullable Boolean and update it in the callback function. I also found it doesn't always finish reporting the result before returning to the main function - I handle for that, too, and make it wait for the result using the timeout:
private static bool? areWeConnected = null;
private static bool checkSocket(string svrAddress, int port)
{
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse(svrAddress), port);
Socket socket = new Socket(endPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
int timeout = 5000; // int.Parse(ConfigurationManager.AppSettings["socketTimeout"].ToString());
int ctr = 0;
IAsyncResult ar = socket.BeginConnect(endPoint, Connect_Callback, socket);
ar.AsyncWaitHandle.WaitOne( timeout, true );
// Sometimes it returns here as null before it's done checking the connection
// No idea why, since .WaitOne() should block that, but it does happen
while (areWeConnected == null && ctr < timeout)
{
Thread.Sleep(100);
ctr += 100;
} // Given 100ms between checks, it allows 50 checks
// for a 5 second timeout before we give up and return false, below
if (areWeConnected == true)
{
return true;
}
else
{
return false;
}
}
private static void Connect_Callback(IAsyncResult ar)
{
areWeConnected = null;
try
{
Socket socket = (Socket)ar.AsyncState;
areWeConnected = socket.Connected;
socket.EndConnect(ar);
}
catch (Exception ex)
{
areWeConnected = false;
// log exception
}
}

The ugly truth of the matter is that if you are asking this question you will probably not be able to design and implement a secure system.
Let me illustrate my point: Imagine you are building a web application and you need to store some session data. You could assign each user a session ID and store the session data on the server in a hash map mapping session ID to session data. But then you have to deal with this pesky state on the server and if at some point you need more than one server things will get messy. So instead you have the idea to store the session data in a cookie on the client side. You will encrypt it of course so the user cannot read and manipulate the data. So what mode should you use? Coming here you read the top answer (sorry for singling you out myforwik). The first one covered - ECB - is not for you, you want to encrypt more than one block, the next one - CBC - sounds good and you don't need the parallelism of CTR, you don't need random access, so no XTS and patents are a PITA, so no OCB. Using your crypto library you realize that you need some padding because you can only encrypt multiples of the block size. You choose PKCS7 because it was defined in some serious cryptography standards. After reading somewhere that CBC is provably secure if used with a random IV and a secure block cipher, you rest at ease even though you are storing your sensitive data on the client side.
Years later after your service has indeed grown to significant size, an IT security specialist contacts you in a responsible disclosure. She's telling you that she can decrypt all your cookies using a padding oracle attack, because your code produces an error page if the padding is somehow broken.
This is not a hypothetical scenario: Microsoft had this exact flaw in ASP.NET until a few years ago.
The problem is there are a lot of pitfalls regarding cryptography and it is extremely easy to build a system that looks secure for the layman but is trivial to break for a knowledgeable attacker.
For live connections use TLS (be sure to check the hostname of the certificate and the issuer chain). If you can't use TLS, look for the highest level API your system has to offer for your task and be sure you understand the guarantees it offers and more important what it does not guarantee. For the example above a framework like Play offers client side storage facilities, it does not invalidate the stored data after some time, though, and if you changed the client side state, an attacker can restore a previous state without you noticing.
If there is no high level abstraction available use a high level crypto library. A prominent example is NaCl and a portable implementation with many language bindings is Sodium. Using such a library you do not have to care about encryption modes etc. but you have to be even more careful about the usage details than with a higher level abstraction, like never using a nonce twice. For custom protocol building (say you want something like TLS, but not over TCP or UDP) there are frameworks like Noise and associated implementations that do most of the heavy lifting for you, but their flexibility also means there is a lot of room for error, if you don't understand in depth what all the components do.
If for some reason you cannot use a high level crypto library, for example because you need to interact with existing system in a specific way, there is no way around educating yourself thoroughly. I recommend reading Cryptography Engineering by Ferguson, Kohno and Schneier. Please don't fool yourself into believing you can build a secure system without the necessary background. Cryptography is extremely subtle and it's nigh impossible to test the security of a system.
To prevent padding oracle attacks and changes to the ciphertext, one can compute a message authentication code (MAC) on the ciphertext and only decrypt it if it has not been tampered with. This is called encrypt-then-mac and should be preferred to any other order. Except for very few use cases authenticity is as important as confidentiality (the latter of which is the aim of encryption). Authenticated encryption schemes (with associated data (AEAD)) combine the two part process of encryption and authentication into one block cipher mode that also produces an authentication tag in the process. In most cases this results in speed improvement.
Considering the importance of authentication I would recommend the following two block cipher modes for most use cases (except for disk encryption purposes): If the data is authenticated by an asymmetric signature use CBC, otherwise use GCM.
you can make guid variable to accept null first using ? operator then you use Guid.Empty or typecast it to null using (Guid?)null;
eg:
Guid? id = Guid.Empty;
or
Guid? id = (Guid?)null;
Just remember, if the field you want to make nullable is part of a primary key, you can't. Primary Keys cannot have null fields.
Use the following code:
if(json.isNull()!= null){ //returns true only if json is not null
}
I may be missing part of the question, but I believe you can simply do this:
$('.testimonial').each((index, element) => {
if (/* Condition */) {
// Do Something
}
});
This uses jQuery's each method: https://learn.jquery.com/using-jquery-core/iterating/

You should not use jQuery in Angular. While it is possible (see other answers for this question), it is discouraged. Why?
Angular holds an own representation of the DOM in its memory and doesn't use query-selectors (functions like document.getElementById(id)
) like jQuery. Instead all the DOM-manipulation is done by Renderer2 (and Angular-directives like *ngFor and *ngIf accessing that Renderer2 in the background/framework-code). If you manipulate DOM with jQuery yourself you will sooner or later...
If you really want to include jQuery (for duck-taping some prototype that you will 100% definitively throw away), I recommend to at least include it in your package.json with npm install --save jquery
instead of getting it from google's CDN.
TLDR: For learning how to manipulate the DOM in the Angular way please go through the official tour-of heroes tutorial first: https://angular.io/tutorial/toh-pt2 If you need to access elements higher up in the DOM hierarchy (parent or
document body
) or for some other reason directives like*ngIf
,*ngFor
, custom directives, pipes and other angular utilities like[style.background]
,[class.myOwnCustomClass]
don't satisfy your needs, use Renderer2: https://www.concretepage.com/angular-2/angular-4-renderer2-example
For my plot (a sns factorplot) the proposed answer didn't works fine.
Thus I use

Logging has different levels such as :
Trace – A fine-grained debug message, typically capturing the flow through the application.
Debug- A general debugging event should be logged under this.
ALL – All events could be logged.
INFO- An informational purpose, information written in plain english.
Warn- An event that might possible lead to an error.
Error- An error in the application, possibly recoverable.
Logging captured with debug level is information helpful to developers as well as other personnel, so it captures in broad range. If your code doesn't have exception or errors then you should be alright to use DEBUG level of logging, otherwise you should carefully choose options.
git rev-parse --show-toplevel
could be enough if executed within a git repo.
From git rev-parse
man page:
--show-toplevel
Show the absolute path of the top-level directory.
For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":
git rev-parse --git-dir
That would give the path of the .git
directory.
The OP mentions:
git rev-parse --show-prefix
which returns the local path under the git repo root. (empty if you are at the git repo root)
Note: for simply checking if one is in a git repo, I find the following command quite expressive:
git rev-parse --is-inside-work-tree
And yes, if you need to check if you are in a .git
git-dir folder:
git rev-parse --is-inside-git-dir
Try this code
ArrayList<String> list = new ArrayList<String>();
JSONArray jsonArray = (JSONArray)jsonObject;
int len = jsonArray.length();
if (jsonArray != null) {
for (int i=0;i<len;i++){
list.add(jsonArray.get(i).toString());
}
}
//Remove the element from arraylist
list.remove(position);
//Recreate JSON Array
JSONArray jsArray = new JSONArray(list);
Edit:
Using ArrayList
will add "\"
to the key and values. So, use JSONArray
itself
JSONArray list = new JSONArray();
JSONArray jsonArray = new JSONArray(jsonstring);
int len = jsonArray.length();
if (jsonArray != null) {
for (int i=0;i<len;i++)
{
//Excluding the item at position
if (i != position)
{
list.put(jsonArray.get(i));
}
}
}
It seems like this issue is not occurring with a specific configuration or node version. We experienced it a couple of times when redeploying and suspect the npm servers to cause this issue.
Retrying a couple of times did solve the issue eventually.
UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

This answer is actually taken from Scott Allen's course titled ASP.NET MVC 5 Fundamentals. I thought I'd share because I think it is slightly simpler and more intuitive than any of the answers here already. Also note according to Scott Allen and other trainings I've done, find method is an optimized way to retrieve a resource from database that can use caching if it already has been retrieved. In this code, collection refers to a DBSet of objects. Object can be any generic object type.
var object = context.collection.Find(id);
context.collection.Remove(object);
context.SaveChanges();
You said:
I want them to always come out as Tanzanian time and not in the local times that various collaborator are in.
If this is the case, then you should not use UTC. All you need to do is to use a DATETIME
type in MySQL instead of a TIMESTAMP
type.
MySQL converts
TIMESTAMP
values from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. (This does not occur for other types such asDATETIME
.)
If you are already using a DATETIME
type, then you must be not setting it by the local time to begin with. You'll need to focus less on the database, and more on your application code - which you didn't show here. The problem, and the solution, will vary drastically depending on language, so be sure to tag the question with the appropriate language of your application code.
You can modify the path on the config.xml
file in the default directory
<projectNamingStrategy class="jenkins.model.ProjectNamingStrategy$DefaultProjectNamingStrategy"/>
<workspaceDir>D:/Workspace/${ITEM_FULL_NAME}</workspaceDir>
<buildsDir>D:/Logs/${ITEM_ROOTDIR}/Build</buildsDir>
Since other solutions are old and either poorly-working or not working at all, I've modified NestedScrollView
, which is stable, modern and it has all you expect from a scroll view. Except for horizontal scrolling.
Here's the repo: https://github.com/ultimate-deej/TwoWayNestedScrollView
I've made no changes, no "improvements" to the original NestedScrollView
expect for what was absolutely necessary.
The code is based on androidx.core:core:1.3.0
, which is the latest stable version at the time of writing.
All of the following works:
NestedScrollView
)If you're currently on the branch you want to rename:
git branch -m new_name
Or else:
git branch -m old_name new_name
You can check with:
git branch -a
As you can see, only the local name changed Now, to change the name also in the remote you must do:
git push origin :old_name
This removes the branch, then upload it with the new name:
git push origin new_name
Our tests were bogus because mine had a typo.
zeroPad = function (num, count) {
return ((num / Math.pow(10, count)) + '').substr(2);
};
Paul's is the fastest, but I think .substr is faster than .slice even if it is one character more ;)
You first create the filter with fspecial and then convolve the image with the filter using imfilter (which works on multidimensional images as in the example).
You specify sigma
and hsize
in fspecial
.
%%# Read an image
I = imread('peppers.png');
%# Create the gaussian filter with hsize = [5 5] and sigma = 2
G = fspecial('gaussian',[5 5],2);
%# Filter it
Ig = imfilter(I,G,'same');
%# Display
imshow(Ig)
os.system
is equivalent to Unix system
command, while subprocess
was a helper module created to provide many of the facilities provided by the Popen
commands with an easier and controllable interface. Those were designed similar to the Unix Popen command.
system()
executes a command specified in command by calling/bin/sh -c command
, and returns after the command has been completed
Whereas:
The
popen()
function opens a process by creating a pipe, forking, and invoking the shell.
If you are thinking which one to use, then use subprocess
definitely because you have all the facilities for execution, plus additional control over the process.
I have a trouble may proof gradlew clean is not equal to ADT build clean. And Now I am struggling to get it fixed.
Here is what I got: I set a configProductID=11111 from my gradle.properties, from my build.gradle, I add
resValue "string", "ProductID", configProductID
If I do a build clean from ADT, the resource R.string.ProductID can be generated. Then I can do bellow command successfully.
gradlew assembleDebug
But, as I am trying to setup build server, I don't want help from ADT IDE, so I need to avoid using ADT build clean. Here comes my problem. Now I change my resource name from "ProductID" to "myProductID", I do:
gradlew clean
I get error

You can use http://www.jsonlint.com/ to edit your json
online if you don't have Notepad++.
You can read it from the input stream:
public ActionResult ManagePhotos(ManagePhotos model)
{
if (ModelState.IsValid)
{
byte[] image = new byte[model.File.ContentLength];
model.File.InputStream.Read(image, 0, image.Length);
// TODO: Do something with the byte array here
}
...
}
And if you intend to directly save the file to the disk you could use the model.File.SaveAs
method. You might find the following blog post useful.
Is this on the client side of things??
If so, you need to create an instance of WsHttpBinding, and an EndpointAddress, and then pass those two to the proxy client constructor that takes these two as parameters.
// using System.ServiceModel;
WSHttpBinding binding = new WSHttpBinding();
EndpointAddress endpoint = new EndpointAddress(new Uri("http://localhost:9000/MyService"));
MyServiceClient client = new MyServiceClient(binding, endpoint);
If it's on the server side of things, you'll need to programmatically create your own instance of ServiceHost, and add the appropriate service endpoints to it.
ServiceHost svcHost = new ServiceHost(typeof(MyService), null);
svcHost.AddServiceEndpoint(typeof(IMyService),
new WSHttpBinding(),
"http://localhost:9000/MyService");
Of course you can have multiple of those service endpoints added to your service host. Once you're done, you need to open the service host by calling the .Open() method.
If you want to be able to dynamically - at runtime - pick which configuration to use, you could define multiple configurations, each with a unique name, and then call the appropriate constructor (for your service host, or your proxy client) with the configuration name you wish to use.
E.g. you could easily have:
<endpoint address="http://mydomain/MyService.svc"
binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IASRService"
contract="ASRService.IASRService"
name="WSHttpBinding_IASRService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="https://mydomain/MyService2.svc"
binding="wsHttpBinding" bindingConfiguration="SecureHttpBinding_IASRService"
contract="ASRService.IASRService"
name="SecureWSHttpBinding_IASRService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="net.tcp://mydomain/MyService3.svc"
binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IASRService"
contract="ASRService.IASRService"
name="NetTcpBinding_IASRService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
(three different names, different parameters by specifying different bindingConfigurations) and then just pick the right one to instantiate your server (or client proxy).
But in both cases - server and client - you have to pick before actually creating the service host or the proxy client. Once created, these are immutable - you cannot tweak them once they're up and running.

For those who prefer using the Task Scheduler, it's possible to schedule a task to run after a restart / shutdown has been initiated by setting the task to run after event 1074 in the System log in the Event Viewer has been logged. However, it's only good for very short task, which will run as long as the system is restarting / shutting down, which is usually only a few seconds.
Begin the task: On an event
Log: System
Source: USER32
EventID: 1074
schtasks /create /tn "taskname" /tr "task file" /sc onevent /ec system /mo *[system/eventid=1074]
Comment: the /ec option is available from Windows Vista and above. (thank you @t2d)
Please note that the task status can be:
The operation being requested was not performed because the user has not logged on to the network. The specified service does not exist. (0x800704DD)
However, it doesn't mean that it didn't run.
Here is the method by using explode
:
$text = explode('_', '233718_This_is_a_string', 2)[1]; // Returns This_is_a_string
or:
$text = @end((explode('_', '233718_This_is_a_string', 2)));
By specifying 2
for the limit
parameter in explode()
, it returns array with 2 maximum elements separated by the string delimiter. Returning 2nd element ([1]
), will give the rest of string.
Here is another one-liner by using strpos
(as suggested by @flu):
$needle = '233718_This_is_a_string';
$text = substr($needle, (strpos($needle, '_') ?: -1) + 1); // Returns This_is_a_string
This will work with either an array, an object or a variable and also escapes the special characters that may break your JS :
function debugToConsole($msg) {
echo "<script>console.log(".json_encode($msg).")</script>";
}
Edit : Added json_encode
to the echo
statement. This will prevent your script from breaking if there are quotes in your $msg
variable.
use this function to get a standard array back of the type you are after...
return get_object_vars($booking);
You can use either:
ActiveCell.Interior.ColorIndex = 28
or
ActiveCell.Interior.Color = RGB(255,0,0)

I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:

SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";

After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}
if you are using rabbitMQ, use this in terminal:
sudo rabbitmqctl list_queues
it will print list of queues with number of pending tasks. for example:
Listing queues ...

celeryev.faa4da32-a225-4f6c-be3b-d8814856d1b6 0
the number in right column is number of tasks in the queue. in above, celery queue has 166 pending task.
In Python, to represent the absence of a value, you can use the None
value types.NoneType.None

Use:
navigateUpTo(new Intent(this, MainActivity.class));
It works starting from API level 16 (4.1), I believe.
To compare entire revisions, it's simply:
svn diff -r 8979:11390
If you want to compare the last committed state against your currently saved working files, you can use convenience keywords:
svn diff -r PREV:HEAD
(Note, without anything specified afterwards, all files in the specified revisions are compared.)
You can compare a specific file if you add the file path afterwards:
svn diff -r 8979:HEAD /path/to/my/file.php
(When trying to find out how to use kdiff3 from WSL git I ended up here and got the final pieces, so I'll post my solution for anyone else also stumbling in here while trying to find that answer)
With Windows update 1903 it is a lot easier; just use wslpath and there is no need to share TMP from Windows to WSL since the Windows side now has access to the WSL filesystem via \wsl$:
[merge]
renormalize = true
guitool = kdiff3
[diff]
tool = kdiff3
[difftool]
prompt = false
[difftool "kdiff3"]
# Unix style paths must be converted to windows path style
cmd = kdiff3.exe \"`wslpath -w $LOCAL`\" \"`wslpath -w $REMOTE`\"
trustExitCode = false
[mergetool]
keepBackup = false
prompt = false
[mergetool "kdiff3"]
path = kdiff3.exe
trustExitCode = false
Steps for using kdiff3 installed on Windows 10 as diff/merge tool for git in WSL:
# If TMP is passed via WSLENV then use it as TMPDIR
[[ ! -z "$WSLENV" && ! -z "$TMP" ]] && export TMPDIR=$TMP
[merge]
renormalize = true
guitool = kdiff3
[diff]
tool = kdiff3
[difftool]
prompt = false
[difftool "kdiff3"]
#path = kdiff3.exe
# Unix style paths must be converted to windows path style by changing '/mnt/c/' or '/c/' to 'c:/'
cmd = kdiff3.exe \"`echo $LOCAL | sed 's_^\\(/mnt\\)\\?/\\([a-z]\\)/_\\2:/_'`\" \"`echo $REMOTE | sed 's_^\\(/mnt\\)\\?/\\([a-z]\\)/_\\2:/_'`\"
trustExitCode = false
[mergetool]
keepBackup = false
prompt = false
[mergetool "kdiff3"]
path = kdiff3.exe
trustExitCode = false
I use Iesi.Collections http://www.codeproject.com/KB/recipes/sets.aspx
It's used in lot of OSS projects, I first came across it in NHibernate
Below solution may help you.
var unmanagedDownloadcountwithfilter = from count in unmanagedDownloadCount.Where(d =>d.downloaddate >= startDate && d.downloaddate <= endDate)
group count by count.unmanagedassetregistryid into grouped
where grouped.Count() > request.Download
select new
{
UnmanagedAssetRegistryID = grouped.Key,
Count = grouped.Count()
};
If you know x
and y
are both strings, using ===
is not strictly necessary, but is still good practice.
Assuming both variables actually are strings, both operators will function identically. However, TS often allows you to pass an object that meets all the requirements of string
rather than an actual string, which may complicate things.
Given the possibility of confusion or changes in the future, your linter is probably correct in demanding ===
. Just go with that.
CSS Level 3 specifies the unset
property value. From MDN:
The unset CSS keyword is the combination of the initial and inherit keywords. Like these two other CSS-wide keywords, it can be applied to any CSS property, including the CSS shorthand all. This keyword resets the property to its inherited value if it inherits from its parent or to its initial value if not. In other words, it behaves like the inherit keyword in the first case and like the initial keyword in the second case.
Unfortunately this value is currently not supported in all browsers, including IE, Safari and Opera. I suggest using transparent
for the time being.
Web applications require more memory, presumably because you have no choice but to compile into a single assembly. I just converted a large legacy site to a web application and have issues with running out of memory, both at compile time with the error message as below :
Unexpected error writing metadata to file '' --
Not enough storage is available to complete this operation.
error, and at runtime with this error message as below :
Exception information:
Exception type: HttpException
Exception message: Exception of type 'System.OutOfMemoryException' was thrown.
at System.Web.Compilation.BuildManager.ReportTopLevelCompilationException()
My recommendation for converting larger sites on memory-constrained legacy hardware is, to choose the option to revert back to the web site model. Even after an initial success problem might creep up later.
A C# version of Miroslav Zadravec's code
for (int i = 0; i < dataGridView1.Columns.Count-1; i++)
{
dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
}
dataGridView1.Columns[dataGridView1.Columns.Count - 1].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
int colw = dataGridView1.Columns[i].Width;
dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
dataGridView1.Columns[i].Width = colw;
}

Here is a work around. You can use filter instead of find; but filter returns an array of matching objects. find
only returns the first match inside an array. So, why not use filter as following;
data.filter(function (x) {
return x.Id === e
})[0];
I had the same problem, and the solution ended up being adding my local machine's IP to the list of inbound rules in the active security group. In the inbound dialog below, enter 22 in the port range, your local IP/32 in the source field, and leave 'custom tcp rule' in the dropdown.
You can do it for any Java char using the one liner here:
System.out.println( "\\u" + Integer.toHexString('÷' | 0x10000).substring(1) );
But it's only going to work for the Unicode characters up to Unicode 3.0, which is why I precised you could do it for any Java char.
Because Java was designed way before Unicode 3.1 came and hence Java's char primitive is inadequate to represent Unicode 3.1 and up: there's not a "one Unicode character to one Java char" mapping anymore (instead a monstrous hack is used).
So you really have to check your requirements here: do you need to support Java char or any possible Unicode character?
From the PHP online documentation:
To explicitly convert a value to boolean, use the (bool) or (boolean) casts.
However, in most cases the cast is unncecessary, since a value will be automatically converted if an operator, function or control structure requires a boolean argument.
When converting to boolean, the following values are considered FALSE:
FALSE
itself 0.0
(zero) "0"
NULL
(including unset variables) TRUE
(including any resource). So, in most cases, it's the same.
On the other hand, the ===
and the ==
are not the same thing. Regularly, you just need the "equals" operator. To clarify:
$a == $b //Equal. TRUE if $a is equal to $b.
$a === $b //Identical. TRUE if $a is equal to $b, and they are of the same type.
For more information, check the "Comparison Operators" page in the PHP online docs.
Hope this helps.
There are many options:
rspec spec # All specs
rspec spec/models # All specs in the models directory
rspec spec/models/a_model_spec.rb # All specs in the some_model model spec
rspec spec/models/a_model_spec.rb:nn # Run the spec that includes line 'nn'
rspec -e"text from a test" # Runs specs that match the text
rspec spec --tag focus # Runs specs that have :focus => true
rspec spec --tag focus:special # Run specs that have :focus => special
rspec spec --tag focus ~skip # Run tests except those with :focus => true
You could do:
svn revert -R .
This will not delete any new file not under version control. But you can easily write a shell script to do that like:
for file in `svn status|grep "^ *?"|sed -e 's/^ *? *//'`; do rm $file ; done
