Since Node v11.0.0 fs promises are available natively without promisify
:
const fs = require('fs').promises;
async function loadMonoCounter() {
const data = await fs.readFile("monolitic.txt", "binary");
return new Buffer(data);
}
This also works....sometimes you may want to construct the definition of the parameters outside of the actual EXEC call.
DECLARE @Parmdef nvarchar (500)
DECLARE @SQL nvarchar (max)
DECLARE @xTxt1 nvarchar (100) = 'test1'
DECLARE @xTxt2 nvarchar (500) = 'test2'
SET @parmdef = '@text1 nvarchar (100), @text2 nvarchar (500)'
SET @SQL = 'PRINT @text1 + '' '' + @text2'
EXEC sp_executeSQL @SQL, @Parmdef, @xTxt1, @xTxt2
To avoid syntax errors, be sure to always put BEGIN
and END
after an IF
clause, eg:
IF (@A!= @SA)
BEGIN
--do stuff
END
IF (@C!= @SC)
BEGIN
--do stuff
END
... and so on. This should work as expected. Imagine BEGIN
and END
keyword as the opening and closing bracket, respectively.
try using:
RAISERROR('your message here!!!',0,1) WITH NOWAIT
you could also try switching to "Results to Text" it is just a few icons to the right of "Execute" on the default tool bar.
With both of the above in place, and you still you do not see the messages, make sure you are running the same server/database/owner version of the procedure that you are editing. Make sure you are hitting the RAISERROR command, make it the first command inside the procedure.
If all else fails, you could create a table:
create table temp_log (RowID int identity(1,1) primary key not null
, MessageValue varchar(255))
then:
INSERT INTO temp_log VALUES ('Your message here')
then after running the procedure (provided no rollbacks) just select
the table.
CASE
isn't used for flow control... for this, you would need to use IF
...
But, there's a set-based solution to this problem instead of the procedural approach:
UPDATE tblEmployee
SET
InOffice = CASE WHEN @NewStatus = 'InOffice' THEN -1 ELSE InOffice END,
OutOffice = CASE WHEN @NewStatus = 'OutOffice' THEN -1 ELSE OutOffice END,
Home = CASE WHEN @NewStatus = 'Home' THEN -1 ELSE Home END
WHERE EmpID = @EmpID
Note that the ELSE
will preserves the original value if the @NewStatus
condition isn't met.
A SELECT INTO
statement creates the table for you. There is no need for the CREATE TABLE
statement before hand.
What is happening is that you create #ivmy_cash_temp1
in your CREATE
statement, then the DB tries to create it for you when you do a SELECT INTO
. This causes an error as it is trying to create a table that you have already created.
Either eliminate the CREATE TABLE
statement or alter your query that fills it to use INSERT INTO SELECT
format.
If you need a unique ID added to your new row then it's best to use SELECT INTO
... since IDENTITY()
only works with this syntax.
If you have the table definition to have an IDENTITY column e.g. IDENTITY(1,1) then don't include MyId in your INSERT INTO statement. The point of IDENTITY is it gives it the next unused value as the primary key value.
insert into MYDB.dbo.MainTable (MyFirstName, MyLastName, MyAddress, MyPort)
values(@myFirstName, @myLastName, @myAddress, @myPort)
There is then no need to pass the @MyId parameter into your stored procedure either. So change it to:
CREATE PROCEDURE [dbo].[sp_Test]
@myFirstName nvarchar(50)
,@myLastName nvarchar(50)
,@myAddress nvarchar(MAX)
,@myPort int
AS
If you want to know what the ID of the newly inserted record is add
SELECT @@IDENTITY
to the end of your procedure. e.g. http://msdn.microsoft.com/en-us/library/ms187342.aspx
You will then be able to pick this up in which ever way you are calling it be it SQL or .NET.
P.s. a better way to show you table definision would have been to script the table and paste the text into your stackoverflow browser window because your screen shot is missing the column properties part where IDENTITY is set via the GUI. To do that right click the table 'Script Table as' --> 'CREATE to' --> Clipboard. You can also do File or New Query Editor Window (all self explanitory) experient and see what you get.
Try this
DataSet ds = new DataSet("TimeRanges");
using(SqlConnection conn = new SqlConnection("ConnectionString"))
{
SqlCommand sqlComm = new SqlCommand("Procedure1", conn);
sqlComm.Parameters.AddWithValue("@Start", StartTime);
sqlComm.Parameters.AddWithValue("@Finish", FinishTime);
sqlComm.Parameters.AddWithValue("@TimeRange", TimeRange);
sqlComm.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = sqlComm;
da.Fill(ds);
}
fyi The code I ended up with:
IF UPDATE (QtyToRepair)
begin
INSERT INTO tmpQtyToRepairChanges (OrderNo, PartNumber, ModifiedDate, ModifiedUser, ModifiedHost, QtyToRepairOld, QtyToRepairNew)
SELECT S.OrderNo, S.PartNumber, GETDATE(), SUSER_NAME(), HOST_NAME(), D.QtyToRepair, I.QtyToRepair FROM SCHEDULE S
INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber
WHERE I.QtyToRepair <> D.QtyToRepair
end
Just use
If @searchType is null means 'return the whole table' then use
WHERE p.[Type] = @SearchType OR @SearchType is NULL
If @searchType is an empty string means 'return the whole table' then use
WHERE p.[Type] = @SearchType OR @SearchType = ''
If @searchType is null or an empty string means 'return the whole table' then use
WHERE p.[Type] = @SearchType OR Coalesce(@SearchType,'') = ''
In this part of your SP:
IF @DateFirst <> '' and @DateLast <> ''
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + @DateFirst
+ ' and convert (Date,DateLog) <=''' + @DateLast
you are trying to concatenate strings and datetimes.
As the datetime
type has higher priority than varchar
/nvarchar
, the +
operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= '''
and others) to datetime or numeric values. And fails.
That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.
To amend the situation, you need to add explicit casting of your datetime variables to strings:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst)
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)
You'll also need to add closing single quotes:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst) + ''''
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''
Simply call test2
from test1
like:
EXEC test2 @newId, @prod, @desc;
Make sure to get @id
using SCOPE_IDENTITY(), which gets the last identity value inserted into an identity column in the same scope:
SELECT @newId = SCOPE_IDENTITY()
Here is the syntax to create a trigger:
CREATE TRIGGER trigger_name
ON { table | view }
[ WITH ENCRYPTION ]
{
{ { FOR | AFTER | INSTEAD OF } { [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] }
[ WITH APPEND ]
[ NOT FOR REPLICATION ]
AS
[ { IF UPDATE ( column )
[ { AND | OR } UPDATE ( column ) ]
[ ...n ]
| IF ( COLUMNS_UPDATED ( ) { bitwise_operator } updated_bitmask )
{ comparison_operator } column_bitmask [ ...n ]
} ]
sql_statement [ ...n ]
}
}
If you want to use On Update you only can do it with the IF UPDATE ( column )
section. That's not possible to do what you are asking.
There are a few misunderstandings in the discussion above.
First, you can always ROLLBACK a transaction... no matter what the state of the transaction. So you only have to check the XACT_STATE before a COMMIT, not before a rollback.
As far as the error in the code, you will want to put the transaction inside the TRY. Then in your CATCH, the first thing you should do is the following:
IF @@TRANCOUNT > 0
ROLLBACK TRANSACTION @transaction
Then, after the statement above, then you can send an email or whatever is needed. (FYI: If you send the email BEFORE the rollback, then you will definitely get the "cannot... write to log file" error.)
This issue was from last year, so I hope you have resolved this by now :-) Remus pointed you in the right direction.
As a rule of thumb... the TRY will immediately jump to the CATCH when there is an error. Then, when you're in the CATCH, you can use the XACT_STATE to decide whether you can commit. But if you always want to ROLLBACK in the catch, then you don't need to check the state at all.
I know this is old, but i stumbled on it with Google.
If you have a return value in your stored procedure say "Return 1" - not using output parameters.
You can do the following - "@RETURN_VALUE" is silently added to every command object. NO NEED TO EXPLICITLY ADD
cmd.ExecuteNonQuery();
rtn = (int)cmd.Parameters["@RETURN_VALUE"].Value;
You pass an undefined rAgent_IP parameter in EXEC instead of the local variable @rAgent_IP.
Still, this trigger will fail if you perform a multi-record INSERT statement.
Try this.
ALTER PROCEDURE [dbo].[sp_ClientNotes_update]
@id uniqueidentifier,
@ordering smallint = NULL,
@title nvarchar(20) = NULL,
@content text = NULL
AS
BEGIN
SET NOCOUNT ON;
UPDATE tbl_ClientNotes
SET ordering=ISNULL(@ordering,ordering),
title=ISNULL(@title,title),
content=ISNULL(@content, content)
WHERE id=@id
END
It might also be worth adding an extra part to the WHERE
clause, if you use transactional replication then it will send another update to the subscriber if all are NULL, to prevent this.
WHERE id=@id AND (@ordering IS NOT NULL OR
@title IS NOT NULL OR
@content IS NOT NULL)
I realize this is a very old thread, but it was very helpful when I had to put together some system documentation for several different servers that were hosting different versions of Sql Server. I ended up creating 4 stored procedures which I am posting here for the benefit of the community. We use Dynamics NAV so the two stored procedures with NAV in the name split the Nav company out of the table name. Enjoy...

You need to treat a table valued udf like a table, eg JOIN it
select Emp_Id
from Employee E JOIN dbo.Splitfn(@Id,',') CSV ON E.Emp_Id = CSV.items
T-SQL doesn't support arrays that I'm aware of.
What's your table structure? You could probably design a query that does this instead:
select
month,
sum(sales)
from sales_table
group by month
order by month
Ok now I've done my research, here is the deal:
In TDS protocol, SET NOCOUNT ON
only saves 9-bytes per query while the text "SET NOCOUNT ON" itself is a whopping 14 bytes. I used to think that 123 row(s) affected
was returned from server in plain text in a separate network packet but that's not the case. It's in fact a small structure called DONE_IN_PROC
embedded in the response. It's not a separate network packet so no roundtrips are wasted.
I think you can stick to default counting behavior almost always without worrying about the performance. There are some cases though, where calculating the number of rows beforehand would impact the performance, such as a forward-only cursor. In that case NOCOUNT might be a necessity. Other than that, there is absolutely no need to follow "use NOCOUNT wherever possible" motto.
Here is a very detailed analysis about insignificance of SET NOCOUNT
setting: http://daleburnett.com/2014/01/everything-ever-wanted-know-set-nocount/
YES YOU CAN.
In your stored procedure, you fill the table @tbRetour
.
At the very end of your stored procedure, you write:
SELECT * FROM @tbRetour
To execute the stored procedure, you write:
USE [...]
GO
DECLARE @return_value int
EXEC @return_value = [dbo].[getEnregistrementWithDetails]
@id_enregistrement_entete = '(guid)'
GO
This is exactly what the OUTPUT
clause in SQL Server 2005 onwards is excellent for.
EXAMPLE
CREATE TABLE [dbo].[test_table](
[LockId] [int] IDENTITY(1,1) NOT NULL,
[StartTime] [datetime] NULL,
[EndTime] [datetime] NULL,
PRIMARY KEY CLUSTERED
(
[LockId] ASC
) ON [PRIMARY]
) ON [PRIMARY]
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 07','2009 JUL 07')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 08','2009 JUL 08')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 09','2009 JUL 09')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 10','2009 JUL 10')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 11','2009 JUL 11')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 12','2009 JUL 12')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 13','2009 JUL 13')
UPDATE test_table
SET StartTime = '2011 JUL 01'
OUTPUT INSERTED.* -- INSERTED reflect the value after the UPDATE, INSERT, or MERGE statement is completed
WHERE
StartTime > '2009 JUL 09'
Results in the following being returned
LockId StartTime EndTime
-------------------------------------------------------
4 2011-07-01 00:00:00.000 2009-07-10 00:00:00.000
5 2011-07-01 00:00:00.000 2009-07-11 00:00:00.000
6 2011-07-01 00:00:00.000 2009-07-12 00:00:00.000
7 2011-07-01 00:00:00.000 2009-07-13 00:00:00.000
In your particular case, since you cannot use aggregate functions with OUTPUT
, you need to capture the output of INSERTED.*
in a table variable or temporary table and count the records. For example,
DECLARE @temp TABLE (
[LockId] [int],
[StartTime] [datetime] NULL,
[EndTime] [datetime] NULL
)
UPDATE test_table
SET StartTime = '2011 JUL 01'
OUTPUT INSERTED.* INTO @temp
WHERE
StartTime > '2009 JUL 09'
-- now get the count of affected records
SELECT COUNT(*) FROM @temp
Your where clause should have worked. I am at a loss as to why it didn't. Let me show you how I would have figured out the problem with the where clause as it might help you for the future.
When I create triggers, I start at the query window by creating a temp table called #inserted (and or #deleted) with all the columns of the table. Then I popultae it with typical values (Always multiple records and I try to hit the test cases in the values)
Then I write my triggers logic and I can test without it actually being in a trigger. In a case like your where clause not doing what was expected, I could easily test by commenting out the insert to see what the select was returning. I would then probably be easily able to see what the problem was. I assure you that where clasues do work in triggers if they are written correctly.
Once I know that the code works properly for all the cases, I global replace #inserted with inserted and add the create trigger code around it and voila, a tested trigger.
AS I said in a comment, I have a concern that the solution you picked will not work properly in a multiple record insert or update. Triggers should always be written to account for that as you cannot predict if and when they will happen (and they do happen eventually to pretty much every table.)
While they are not the same thing, in one sense DISTINCT
implies a GROUP BY
, because every DISTINCT
could be re-written using GROUP BY
instead. With that in mind, it doesn't make sense to order by something that's not in the aggregate group.
For example, if you have a table like this:
col1 col2 ---- ---- 1 1 1 2 2 1 2 2 2 3 3 1
and then try to query it like this:
SELECT DISTINCT col1 FROM [table] WHERE col2 > 2 ORDER BY col1, col2
That would make no sense, because there could end up being multiple col2
values per row. Which one should it use for the order? Of course, in this query you know the results wouldn't be that way, but the database server can't know that in advance.
Now, your case is a little different. You included all the columns from the order by
clause in the select
clause, and therefore it would seem at first glance that they were all grouped. However, some of those columns were included in a calculated field. When you do that in combination with distinct, the distinct
directive can only be applied to the final results of the calculation: it doesn't know anything about the source of the calculation any more.
This means the server doesn't really know it can count on those columns any more. It knows that they were used, but it doesn't know if the calculation operation might cause an effect similar to my first simple example above.
So now you need to do something else to tell the server that the columns are okay to use for ordering. There are several ways to do that, but this approach should work okay:
SELECT rsc.RadioServiceCodeId,
rsc.RadioServiceCode + ' - ' + rsc.RadioService as RadioService
FROM sbi_l_radioservicecodes rsc
INNER JOIN sbi_l_radioservicecodegroups rscg
ON rsc.radioservicecodeid = rscg.radioservicecodeid
WHERE rscg.radioservicegroupid IN
(SELECT val FROM dbo.fnParseArray(@RadioServiceGroup,','))
OR @RadioServiceGroup IS NULL
GROUP BY rsc.RadioServiceCode,rsc.RadioServiceCodeId,rsc.RadioService
ORDER BY rsc.RadioServiceCode,rsc.RadioServiceCodeId,rsc.RadioService
Yet, another really simple solution is this one:
html, body {
height: 100%;
width: 100%;
margin: 0;
display: table;
}
footer {
background-color: grey;
display: table-row;
height: 0;
}
The trick is to use a display:table
for the whole document and display:table-row
with height:0
for the footer.
Since the footer is the only body child that has a display as table-row
, it is rendered at the bottom of the page.

?By placing the div
before the h1
and floating it to the right
, you get the desired effect.
Some notes of my experience converting Mercurial to Git.
Using hg-fast-export failed and I needed --force as noted above. Next I got this error:
error: cannot lock ref 'refs/heads/stable': 'refs/heads/stable/sub-branch-name' exists; cannot create 'refs/heads/stable'
Upon completion of the hg-fast-export I ended up with an amputated repo. I think that this repo had a good few orphaned branches and that hg-fast-export needs a somewhat idealised repo. This all seemed a bit rough around the edges, so I moved on to Kiln Harmony (http://blog.fogcreek.com/announcing-kiln-harmony-the-future-of-dvcs/)
Kiln Harmony does not appear to exist on a free tier account as suggested above. I could choose between Git-only and Mercurial-only repos and there is no option to switch. I raised a support ticket and will share the result if they reply.
The Hg-Git mercurial plugin (http://hg-git.github.io/) did work for me. FYI on Mac OSX I installed hg-git via macports as follows:
.hgrc needs these lines:
[ui]
username = Name Surname <[email protected]>
[extensions]
hgext.bookmarks =
hggit =
I then had success with:
hg push git+ssh://[email protected]:myaccount/myrepo.git
All the above are blunt instruments and I only pushed ahead because it took enough time to get the team to use git properly.
Upon first pushing the project per (3) I ended up with all new changes missing. This is because this line of code must be viewed as a guide only:
$ hg bookmark -r default master # make a bookmark of master for default, so a ref gets created
The theory is that the default branch can be deemed to be master when pushing to git, and in my case I inherited a repo where they used 'stable' as the equivalent of master. Moreover, I also discovered that the tip of the repo was a hotfix not yet merged with the 'stable' branch.
Without properly understanding both Mercurial and the repo to be converted, you are probably better off not doing the conversion.
I did the following in order to get the repo ready for a second conversion attempt:
hg update -C stable
hg merge stable/hotfix-feature
hg ci -m "Merge with stable branch"
hg push git+ssh://[email protected]:myaccount/myrepo.git
After this I had a verifiably equivalent project in git, however all the orphaned branches I mentioned earlier are gone. I don't think that is too serious, but I may well live to regret this as an oversight. Therefore my final thought is to keep the original anyway.
Edit: If you just want the latest commit in git, this is simpler than the above merge:
hg book -r tip master
hg push git+ssh://[email protected]:myaccount/myrepo.git
Using Guava (r07) you can do this:
for(char c : Lists.charactersOf(someString)) { ... }
This has the convenience of using foreach while not copying the string to a new array. Lists.charactersOf
returns a view of the string as a List
.
Enclose your text in

UTF-8 is not a character set, it's an encoding. The character set for UTF-8 is Unicode. If you want to store Unicode text you use the nvarchar
data type.
If the database would use UTF-8 to store text, you would still not get the text out as encoded UTF-8 data, you would get it out as decoded text.
You can easily store UTF-8 encoded text in the database, but then you don't store it as text, you store it as binary data (varbinary
).

EDIT:
This answer will not work for Python3 and will give a RuntimeError
.
RuntimeError: dictionary changed size during iteration.
This happens because mydict.keys()
returns an iterator not a list.
As pointed out in comments simply convert mydict.keys()
to a list by list(mydict.keys())
and it should work.
A simple test in the console shows you cannot modify a dictionary while iterating over it:
>>> mydict = {'one': 1, 'two': 2, 'three': 3, 'four': 4}
>>> for k, v in mydict.iteritems():
... if k == 'two':
... del mydict[k]
...
------------------------------------------------------------
Traceback (most recent call last):
File "<ipython console>", line 1, in <module>
RuntimeError: dictionary changed size during iteration
As stated in delnan's answer, deleting entries causes problems when the iterator tries to move onto the next entry. Instead, use the keys()
method to get a list of the keys and work with that:
>>> for k in mydict.keys():
... if k == 'two':
... del mydict[k]
...
>>> mydict
{'four': 4, 'three': 3, 'one': 1}
If you need to delete based on the items value, use the items()
method instead:
>>> for k, v in mydict.items():
... if v == 3:
... del mydict[k]
...
>>> mydict
{'four': 4, 'one': 1}
For ASP.NET5, i.e. ASPNETCORE, you can do the following in configure
:
app.UseRequestLocalization(new RequestLocalizationOptions
{
DefaultRequestCulture = new RequestCulture(new CultureInfo("en-gb")),
SupportedCultures = new List<CultureInfo>
{
new CultureInfo("en-gb")
},
SupportedUICultures = new List<CultureInfo>
{
new CultureInfo("en-gb")
}
});
Here's a series of blog posts that gives more information.
1) Download new PHP from the official site (better some zip). Old php
directory rename to php_old
and create again php
directory and put there unzipped files.
In php.ini
connect needed modules if you used something that was turned off by default (like Memcached etc.), but doesn't forget to add corresponding .dll
files.
2) In my case, I had to update Apache. So repeat the same steps: download the new package, rename directories, create new apache
directory and put their new files.
Now you can try to restart apache running apache_start.bat
from xampp
folder (better run this bat, than restart apache service from Windows services window, cause in this case in console you'll see all errors if there will be some, including lines in config where you'll have problem). If you updated Apache and run this file, in the list of services you'll see Apache2.2, but in description you can get another version (in my case that was Apache/2.4.7).
In case of Apache update you can get some problems, so mind:
after you replace the whole directory, you may need to configure you apache/conf/httpd.conf
file (copy virtual hosts from old config, set up DocumentRoots, permissions for directories, all paths, extend the list of index files (by default apache has only index.html
so other index files will be just ignored and Apache will just list the site root directory in browser), configure you logs etc.)
connect modules you need (if you used something that was not turned on by default like mod_rewrite etc.)
an example
$ echo "something" | mailx -s "subject" [email protected]
to send attachment
$ uuencode file file | mailx -s "subject" [email protected]
and to send attachment AND write the message body
$ (echo "something\n" ; uuencode file file) | mailx -s "subject" [email protected]
I know the answers were correct at the time of asking the question - but since people (like me this minute) still happen to find them wondering why their WildFly 10 was behaving differently, I'd like to give an update for the current Hibernate 5.x version:
In the Hibernate 5.2 User Guide it is stated in chapter 11.2. Applying fetch strategies:
The Hibernate recommendation is to statically mark all associations lazy and to use dynamic fetching strategies for eagerness. This is unfortunately at odds with the JPA specification which defines that all one-to-one and many-to-one associations should be eagerly fetched by default. Hibernate, as a JPA provider, honors that default.
So Hibernate as well behaves like Ashish Agarwal stated above for JPA:
OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER
(see JPA 2.1 Spec)
I just wanted to supplement MajesticRa's recommendation of OxyPlot, and point out how OxyPlot can be used for a variety of plotting cases. The software is free and Open-Source, very polished, and allows for a variety of uses beyon normal 2D mapping.
I've been using OxyPlot for an unorthodox project, where I display (in WPF/C#) a map (Robotic Occupancy Grid) which I could overlay with LineSeries (Path Traveled) and PointSeries (Way Points). Using the OxyPlot ImageAnnotation feature I am able to display 60Hz Video within my OxyPlot, by periodically updating the ImageAnnotation on its own thread, while mapping Series of points overtop the video. The background video and points are even scalable and translatable.
Hopefully this is helpful for other looking to display plots overtop of images and videos.
For me, the perfect example for threading is monitoring asynchronous events. Look at this code.
# thread_test.py
import threading
import time
class Monitor(threading.Thread):
def __init__(self, mon):
threading.Thread.__init__(self)
self.mon = mon
def run(self):
while True:
if self.mon[0] == 2:
print "Mon = 2"
self.mon[0] = 3;
You can play with this code by opening an IPython session and doing something like:
>>> from thread_test import Monitor
>>> a = [0]
>>> mon = Monitor(a)
>>> mon.start()
>>> a[0] = 2
Mon = 2
>>>a[0] = 2
Mon = 2
Wait a few minutes
>>> a[0] = 2
Mon = 2
use quick tip using top command in linux/unix
$ top
and then hit Shift+m (i.e. write a capital M
).
From man top
SORTING of task window
For compatibility, this top supports most of the former top sort keys.
Since this is primarily a service to former top users, these commands do
not appear on any help screen.
command sorted-field supported
A start time (non-display) No
M %MEM Yes
N PID Yes
P %CPU Yes
T TIME+ Yes
Or alternatively: hit Shift + f , then choose the display to order by memory usage by hitting key n then press Enter. You will see active process ordered by memory usage
Here are some useful links:
The 2nd column is the keyCode and the html column shows how it will displayed. You can test it here.
On Linux/Unix (note: Mac OS is a Unix) use top
and press M (Shift+M) to sort processes by memory usage.
On Windows use the Task Manager.
You CAN include a modal within a form. In the Bootstrap documentation it recommends the modal to be a "top level" element, but it still works within a form.
You create a form, and then the modal "save" button will be a button of type="submit" to submit the form from within the modal.
<form asp-action="AddUsersToRole" method="POST" class="mb-3">
@await Html.PartialAsync("~/Views/Users/_SelectList.cshtml", Model.Users)
<div class="modal fade" id="role-select-modal" tabindex="-1" role="dialog" aria-labelledby="role-select-modal" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Select a Role</h5>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Add Users to Role</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
</div>
</div>
</div>
</div>
</form>
You can post (or GET) your form data to any URL. By default it is the serving page URL, but you can change it by setting the form action
. You do not have to use ajax.
Are you sure you want to use __getattribute__
? What are you actually trying to achieve?
The easiest way to do what you ask is:
class D(object):
def __init__(self):
self.test = 20
self.test2 = 21
test = 0
or:
class D(object):
def __init__(self):
self.test = 20
self.test2 = 21
@property
def test(self):
return 0
Edit:
Note that an instance of D
would have different values of test
in each case. In the first case d.test
would be 20, in the second it would be 0. I'll leave it to you to work out why.
Edit2:
Greg pointed out that example 2 will fail because the property is read only and the __init__
method tried to set it to 20. A more complete example for that would be:
class D(object):
def __init__(self):
self.test = 20
self.test2 = 21
_test = 0
def get_test(self):
return self._test
def set_test(self, value):
self._test = value
test = property(get_test, set_test)
Obviously, as a class this is almost entirely useless, but it gives you an idea to move on from.
Please use dataset
var article = document.querySelector('#electriccars'),
data = article.dataset;
// data.columns -> "3"
// data.indexnumber -> "12314"
// data.parent -> "cars"
so in your case for setting data:
getElementById('item1').dataset.icon = "base2.gif";
In the event that you need to do this with JSON:
=CONCATENATE("'{""service"": { ""field"": "&A2&"}}'")
I encountered the same problem in the code and What I did is I found out all the changes I have made from the last correct compilation. And I have observed one function declaration was without ";" and also it was passing a value and I have declared it to pass nothing "void". this method will surely solve the problem for many.

Comments on each piece of your DTD below. Refer to official spec for more info.
<!
DOCTYPE ----------------------------------------- correct
templates --------------------------------------- correct Name matches root element.
PUBLIC ------------------------------------------ correct Accessing external subset via URL.
"//UNKNOWN/" ------------------------------------ invalid? Seems useless, wrong, out-of-place.
Safely replaceable by DTD URL in next line.
"http://fast-code.sourceforge.net/template.dtd" - invalid URL is currently broken.

Simple Explanation:
An extremely basic DTD will look like the second line here:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE nameOfYourRootElement>
<nameOfYourRootElement>
</nameOfYourRootElement>
Detailed Explanation:
DTDs serve to establish agreed upon data formats and validate the receipt of such data. They define the structure of an XML document, including:
E.g.
<!DOCTYPE nameOfYourRootElement
[
<!ELEMENT nameOfYourRootElement (nameOfChildElement1,nameOfChildElement2)>
<!ELEMENT nameOfChildElement1 (#PCDATA)>
<!ELEMENT nameOfChildElement2 (#PCDATA)>
<!ENTITY nbsp " ">
<!ENTITY author "Your Author Name">
]>
Meaning of above lines...
Line 1) Root element defined as "nameOfYourRootElement"
Line 2) Start of element definitions
Line 3) Root element children defined as "nameOfYourRootElement1" and "nameOfYourRootElement2"
Line 4) Child element, which is defined as data type #PCDATA
Line 5) Child element, which is defined as data type #PCDATA
Line 6) Expand instances of
to  
when document is parsed by XML parser
Line 7) Expand instances of &author;
to Your Author Name
when document is parsed by XML parser
Line 8) End of definitions
<p>Which one true?</p>
<select id="sel">
<option>-</option>
<option>A</option>
<option>B</option>
<option>C</option>
</select>
( display just first option of all options)
document.getElementById("sel").options.length=1;
The new Array method .filter() would work well for this:
var filteredArray = array.filter(function (element) {
return element.id === 0;
});
jQuery can also do this with .grep()
edit: it is worth mentioning that both of these functions just iterate under the hood, there won't be a noticeable performance difference between them and rolling your own filter function, but why re-invent the wheel.
To my knowledge the only way to achieve this in a native select would be to use the unicode representations of the font. You'll have to apply the glyphicon font to the select and as such can't mix it with other fonts. However, glyphicons include regular characters, so you can add text. Unfortunately setting the font for individual options doesn't seem to be possible.
<select class="form-control glyphicon">
<option value="">− − − Hello</option>
<option value="glyphicon-list-alt"> Text</option>
</select>
Here's a list of the icons with their unicode:
Load - Test S/W at max Load. Stress - Beyond the Load of S/W.Or To determine the breaking point of s/w.
Try initializing the ks
variable inside your submit function.
(function($){
$(document).ready(function(){
$('#data').submit(function(e){
var ks = $('#keywords').val().split("\n");
e.preventDefault();
alert(ks[0]);
$.each(ks, function(k){
alert(k);
});
});
});
})(jQuery);
In case you want to have a separator in the name between levels, this function works well.
def flattenHierarchicalCol(col,sep = '_'):
if not type(col) is tuple:
return col
else:
new_col = ''
for leveli,level in enumerate(col):
if not level == '':
if not leveli == 0:
new_col += sep
new_col += level
return new_col
df.columns = df.columns.map(flattenHierarchicalCol)
It's always problematic and often misleading to try and translate constructs and concepts between languages. Casting is no exception. Particularly because Java is a dynamic language and C++ is somewhat different.
All casting in Java, no matter how you do it, is done at runtime. Type information is held at runtime. C++ is a bit more of a mix. You can cast a struct in C++ to another and it's merely a reinterpretation of the bytes that represent those structs. Java doesn't work that way.
Also generics in Java and C++ are vastly different. Don't concern yourself overly with how you do C++ things in Java. You need to learn how to do things the Java way.
Use the .readline()
method (Python 2 docs, Python 3 docs):
with open('myfile.txt') as f:
first_line = f.readline()
Some notes:
f.readline()
will contain a trailing newline. You may wish to use f.readline().strip()
instead to remove the newline.with
statement automatically closes the file again when the block ends.with
statement only works in Python 2.5 and up, and in Python 2.5 you need to use from __future__ import with_statement
Like this:
#include <vector>
// ...
std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));
(Pre-C++11 you need to leave whitespace between the angled brackets.)
There are various data structures which are optimized for adding elements at the first index. Mind though, that if you convert your collection to one of these, the conversation will probably need a time and space complexity of O(n)
The JDK includes the Deque
structure which offers methods like addFirst(e)
and offerFirst(e)
Deque<String> deque = new LinkedList<>();
deque.add("two");
deque.add("one");
deque.addFirst("three");
//prints "three", "two", "one"
Space and time complexity of insertion is with LinkedList
constant (O(1)
). See the Big-O cheatsheet.
A very easy but inefficient method is to use reverse:
Collections.reverse(list);
list.add(elementForTop);
Collections.reverse(list);
If you use Java 8 streams, this answer might interest you.
O(n)
O(1)
Looking at the JDK implementation this has a O(n)
time complexity so only suitable for very small lists.
Looking for EventHandling, ActionListener?
or code?
JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
textfield.setText("");
//textfield.setText(null); //or use this
}
});

You could format the dates before you add them to your array. That is how I did. I used AngularJS
//convert the date to a standard format
var dt = new Date(date);
//take only the date and month and push them to your label array
$rootScope.charts.mainChart.labels.push(dt.getDate() + "-" + (dt.getMonth() + 1));
Use this array in your chart presentation
All answers posted so far are giving the right solutions, however no one answer was able to properly explain the underlying cause of the concrete problem.
Facelets is a XML based view technology which uses XHTML+XML to generate HTML output. XML has five special characters which has special treatment by the XML parser:
<
the start of a tag.>
the end of a tag."
the start and end of an attribute value.'
the alternative start and end of an attribute value.&
the start of an entity (which ends with ;
).In case of &
which is not followed by #
(e.g.  
,  
, etc), the XML parser is implicitly looking for one of the five predefined entity names lt
, gt
, amp
, quot
and apos
, or any manually defined entity name. However, in your particular case, you was using &
as a JavaScript operator, not as an XML entity. This totally explains the XML parsing error you got:
The entity name must immediately follow the '&' in the entity reference
In essence, you're writing JavaScript code in the wrong place, a XML document instead of a JS file, so you should be escaping all XML special characters accordingly. The &
must be escaped as &
.
So, in your particular case, the
if (Modernizr.canvas && Modernizr.localstorage &&
must become
if (Modernizr.canvas && Modernizr.localstorage &&
to make it XML-valid.
However, this makes the JavaScript code harder to read and maintain. As stated in Mozilla Developer Network's excellent document Writing JavaScript for XHTML, you should be placing the JavaScript code in a character data (CDATA) block. Thus, in JSF terms, that would be:
<h:outputScript>
<![CDATA[
// ...
]]>
</h:outputScript>
The XML parser will interpret the block's contents as "plain vanilla" character data and not as XML and hence interpret the XML special characters "as-is".
But, much better is to just put the JS code in its own JS file which you include by <script src>
, or in JSF terms, the <h:outputScript>
.
<h:outputScript name="onload.js" target="body" />
(note the target="body"
; this way JSF will automatically render the <script>
at the very end of <body>
, regardless of where <h:outputScript>
itself is located, hereby achieving the same effect as with window.onload
and $(document).ready()
; so you don't need to use those anymore in that script)
This way you don't need to worry about XML-special characters in your JS code. As an additional bonus, this gives you the opportunity to let the browser cache the JS file so that total response size is smaller.
Make sure the outermost div has the following CSS properties:
.outer {
/* ... */
height: auto;
overflow: hidden;
/* ... */
}
From your previous comments you said a -journal file was present.
This could mean that you have opened and (EXCLUSIVE?) transaction and have not yet committed the data. Did your program or some other process leave the -journal behind??
Restarting the sqlite process will look at the journal file and clean up any uncommitted actions and remove the -journal file.
This is not an Array. Better declare it like this:
var assoc_pagine = {};
assoc_pagine["home"]=0;
assoc_pagine["about"]=1;
assoc_pagine["work"]=2;
or
var assoc_pagine = {
home:0,
about:1,
work:2
};
To check if an object contains some label you simply do something like this:
if('work' in assoc_pagine){
// do your thing
};
In addition to Varun Achar's answer, this is the Java 8 variant I came up with, that uses java.time.LocalDate and ZonedDateTime instead of the old java.util.Date classes.
public class LocalDateDeserializer extends JsonDeserializer<LocalDate> {
@Override
public LocalDate deserialize(JsonParser jsonparser, DeserializationContext deserializationcontext) throws IOException {
String string = jsonparser.getText();
if(string.length() > 20) {
ZonedDateTime zonedDateTime = ZonedDateTime.parse(string);
return zonedDateTime.toLocalDate();
}
return LocalDate.parse(string);
}
}
Should be noted that strip()
method would trim any leading and trailing whitespace characters from the string (if there is no passed-in argument). If you want to trim space character(s), while keeping the others (like newline), this answer might be helpful:
sample = ' some string\n'
sample_modified = sample.strip(' ')
print(sample_modified) # will print 'some string\n'
strip([chars])
: You can pass in optional characters to strip([chars])
method. Python will look for occurrences of these characters and trim the given string accordingly.
If Table variable has large data, then instead of table variable(@table) create temp table (#table).table variable doesn't allow to create index after insert.
CREATE TABLE #Table(C1 int,
C2 NVarchar(100) , C3 varchar(100)
UNIQUE CLUSTERED (c1)
);
Create table with unique clustered index
Insert data into Temp "#Table" table
Create non clustered indexes.
CREATE NONCLUSTERED INDEX IX1 ON #Table (C2,C3);
What about creating an Extension Method like this....
public static string ReplaceTHAT(this string s)
{
return s.Replace("\n\r", "");
}
And then when you want to replace that wherever you want you can do this.
s.ReplaceTHAT();
Best Regards!
Putting on my gravedigger hat...
The best way I've found to address this is at compile time. Since you're the one setting prefix anyway might as well tell the executable explicitly where to find its shared libraries. Unlike OpenSSL and other software packages, Python doesn't give you nice configure directives to handle alternate library paths (not everyone is root you know...) In the simplest case all you need is the following:
./configure --enable-shared \
--prefix=/usr/local \
LDFLAGS="-Wl,--rpath=/usr/local/lib"
Or if you prefer the non-linux version:
./configure --enable-shared \
--prefix=/usr/local \
LDFLAGS="-R/usr/local/lib"
The "rpath
" flag tells python it has runtime libraries it needs in that particular path. You can take this idea further to handle dependencies installed to a different location than the standard system locations. For example, on my systems since I don't have root access and need to make almost completely self-contained Python installs, my configure line looks like this:
./configure --enable-shared \
--with-system-ffi \
--with-system-expat \
--enable-unicode=ucs4 \
--prefix=/apps/python-${PYTHON_VERSION} \
LDFLAGS="-L/apps/python-${PYTHON_VERSION}/extlib/lib -Wl,--rpath=/apps/python-${PYTHON_VERSION}/lib -Wl,--rpath=/apps/python-${PYTHON_VERSION}/extlib/lib" \
CPPFLAGS="-I/apps/python-${PYTHON_VERSION}/extlib/include"
In this case I am compiling the libraries that python uses (like ffi
, readline
, etc) into an extlib
directory within the python directory tree itself. This way I can tar the python-${PYTHON_VERSION} directory and land it anywhere and it will "work" (provided you don't run into libc
or libm
conflicts). This also helps when trying to run multiple versions of Python on the same box, as you don't need to keep changing your LD_LIBRARY_PATH
or worry about picking up the wrong version of the Python library.
Edit: Forgot to mention, the compile will complain if you don't set the PYTHONPATH
environment variable to what you use as your prefix and fail to compile some modules, e.g., to extend the above example, set the PYTHONPATH
to the prefix used in the above example with export PYTHONPATH=/apps/python-${PYTHON_VERSION}
...
You can use the JSON.stringify function with unformatted JSON. It outputs it in a formatted way.
JSON.stringify({ foo: "sample", bar: "sample" }, null, 4)
This turns
{ "foo": "sample", "bar": "sample" }
into
{
"foo": "sample",
"bar": "sample"
}
Now the data is a readable format you can use the Google Code Prettify script as suggested by @A. Levy to colour code it.
It is worth adding that IE7 and older browsers do not support the JSON.stringify method.
In my case, the database was related to an old Sharepoint install. Stopping and disabling related services in the server manager "unhung" the take offline action, which had been running for 40 minutes, and it completed immediately.
You may wish to check if any services are currently utilizing the database.
Seeing as Guava gets a mention, I thought I would also suggest Eclipse Collections (formerly known as GS Collections).
The following examples all return a List
with a single item.
Lists.mutable.of("Just one item");
Lists.mutable.with("Or use with");
Lists.immutable.of("Maybe it must be immutable?");
Lists.immutable.with("And use with if you want");
There are similar methods for other collections.
You've already done it correctly by using a DateTime
parameter with the value from the DateTime
, so it should already work. Forget about ToString()
- since that isn't used here.
If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).
I have a table and the date-times in it are in the format:
2011-07-01 15:17:33.357
Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281
. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

22.7 usec: itemgetter(87, 342, 217, 998, 500)(myBigList)
24.6 usec: list( myBigList[i] for i in [87, 342, 217, 998, 500] )
Note that in Python 3, the 1st was changed to be the same as the 4th.
Another option would be to start out with a numpy.array
which allows indexing via a list or a numpy.array
:
>>> import numpy
>>> myBigList = numpy.array(range(1000))
>>> myBigList[(87, 342, 217, 998, 500)]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IndexError: invalid index
>>> myBigList[[87, 342, 217, 998, 500]]
array([ 87, 342, 217, 998, 500])
>>> myBigList[numpy.array([87, 342, 217, 998, 500])]
array([ 87, 342, 217, 998, 500])
The tuple
doesn't work the same way as those are slices.
Just on this, and I'm surprised it hasn't been mentioned yet, is to get the correct IP addresses of those sites that are nestled behind the likes of CloudFlare infrastructure. It will break your IP addresses, and give them all the same value. Fortunately they have some server headers available too. Instead of me rewriting what's already been written, have a look here for a more concise answer, and yes, I went through this process a long while ago too. https://stackoverflow.com/a/14985633/1190051
It looks as if you are using the URL.toString
result as the argument to the FileReader
constructor. URL.toString
is a bit broken, and instead you should generally use url.toURI().toString()
. In any case, the string is not a file path.
Instead, you should either:
URL
to ServicesLoader
and let it call openStream
or similar.Class.getResourceAsStream
and just pass the stream over, possibly inside an InputSource
. (Remember to check for nulls as the API is a bit messy.)Scannotation and Reflections use class path scanning approach:
Reflections reflections = new Reflections("my.package");
Set<Class<? extends Object>> classes = reflections.getSubTypesOf(Object.class);
Another approach is to use Java Pluggable Annotation Processing API to write annotation processor which will collect all annotated classes at compile time and build the index file for runtime use. This mechanism is implemented in ClassIndex library:
Iterable<Class> classes = ClassIndex.getPackageClasses("my.package");
This answer extends on Jayson's excellent answer with some more opinionated guidance on the best approach for your use case:
Managing versions manually is probably the worst option. If you decide to manually switch versions, you can use this Bash code instead of Jayson's verbose code (code snippet from the homebrew-openjdk README:
jdk() {
version=$1
export JAVA_HOME=$(/usr/libexec/java_home -v"$version");
java -version
}
Jayson's answer provides the basic commands for SDKMAN and jenv. Here's more info on SDKMAN and more info on jenv if you'd like more background on these tools.
this solved it to me:
sudo apt-get update
sudo apt-get install libglfw3
sudo apt-get install libglfw3-dev
taken from https://github.com/glfw/glfw/issues/808
If you want to go beyond binary evaluation and keep your CSS out of your controller you can implement a simple filter that evaluates the input against a map object:
angular.module('myApp.filters, [])
.filter('switch', function () {
return function (input, map) {
return map[input] || '';
};
});
This allows you to write your markup like this:
<div ng-class="muppets.star|switch:{'Kermit':'green', 'Miss Piggy': 'pink', 'Animal': 'loud'}">
...
</div>
I had the same issue when I used a DockerFile. My Docker is based on the php:5.5-apache image.
I got that error when executing the command "RUN docker-php-ext-install soap"
I have solved it by adding the following command to my DockerFile
"RUN apt-get update && apt-get install -y libxml2-dev"
pip install --download
is deprecated. Starting from version 8.0.0 you should use pip download
command:
pip download <package-name>
Use the command line, not the Python shell (DOS, PowerShell in Windows).
C:\Program Files\Python2.7\Scripts> pip install XYZ
If you installed Python into your PATH using the latest installers, you don't need to be in that folder to run pip
Terminal in Mac or Linux
$ pip install XYZ
Also check this article. Supposedly Microsoft released their Enterprise Library (v4.0) from their patterns and practices where they cover the validation subject but god knows why they didn't included validation for WPF, so the blog post I'm directing you to, explains what the author did to adapt it. Hope this helps!
Your question is very poorly worded. Your code (sort of) already does what you want. What exactly are you confused about? x.numpy()
answer the original title of your question:
Pytorch tensor to numpy array
you need improve your question starting with your title.
Anyway, just in case this is useful to others. You might need to call detach for your code to work. e.g.
RuntimeError: Can't call numpy() on Variable that requires grad.
So call .detach()
. Sample code:
# creating data and running through a nn and saving it
import torch
import torch.nn as nn
from pathlib import Path
from collections import OrderedDict
import numpy as np
path = Path('~/data/tmp/').expanduser()
path.mkdir(parents=True, exist_ok=True)
num_samples = 3
Din, Dout = 1, 1
lb, ub = -1, 1
x = torch.torch.distributions.Uniform(low=lb, high=ub).sample((num_samples, Din))
f = nn.Sequential(OrderedDict([
('f1', nn.Linear(Din,Dout)),
('out', nn.SELU())
]))
y = f(x)
# save data
y.numpy()
x_np, y_np = x.detach().cpu().numpy(), y.detach().cpu().numpy()
np.savez(path / 'db', x=x_np, y=y_np)
print(x_np)
cpu goes after detach. See: https://discuss.pytorch.org/t/should-it-really-be-necessary-to-do-var-detach-cpu-numpy/35489/5
Also I won't make any comments on the slicking since that is off topic and that should not be the focus of your question. See this:
You can also use START WITH
to start a sequence from a particular point, although setval accomplishes the same thing, as in Euler's answer, eg,
SELECT MAX(a) + 1 FROM foo;
CREATE SEQUENCE foo_a_seq START WITH 12345; -- replace 12345 with max above
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq');
$this->db->like()
automatically adds the %s and escapes the string. So all you need is
$this->db->like('title', $query);
$res = $this->db->get('film');
Very simple example and it always works.

params.width = ViewGroup.LayoutParams.MATCH_PARENT;
} else {
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
params.width = ViewGroup.LayoutParams.WRAP_CONTENT;
}

});
}
All the answer explain the problem really good.
However, I would like to add another information.
I faced the same problem at the moment I wanted the output of a function to be a vector.
In this situation, the common solution is to declare the output as an argument of the function itself. This way, the alloc
of the variable and the physical space necessary to store the information are managed outside the function. Pseudocode to explain the classical solution is:
void function(int input, int* output){
//...
output[0] = something;
output[1] = somethig_else;
//...
return;
}
In this case, the example code within the question should be changed in:
void foo(int x, char* a){
if(x < 0){
char b = "blah";
//...
strcpy(a, b);
//..
return;
}
//..
}
Try writing the following batch file and executing it:
Echo one
cmd
Echo two
cmd
Echo three
cmd
Only the first two lines get executed. But if you type "exit" at the command prompt, the next two lines are processed. It's a shell loading another.
To be sure that this is not what is happening in your script, just type "exit" when the first command ends.
HTH!
Try this:
CSS
.style1{
background-color:red;
color:white;
font-size:44px;
}
HTML
<div id="foo">hello world!</div>
<img src="zoom.png" onclick="myFunction()" />
Javascript
function myFunction()
{
document.getElementById('foo').setAttribute("class", "style1");
}
to Print JSON parsed object just type
console.log( JSON.stringify(data, null, " ") );
and you will get output very clear
Why don't you build a DataTable
first then assign it to the DataGridView
as DataSource
:
DataTable table4DataSource=new DataTable();
table4DataSource.Columns.Add("col00");
table4DataSource.Columns.Add("col01");
table4DataSource.Columns.Add("col02");
...
(add your rows, manually, in a circle or via a DataReader
from a database table)
(assign the datasource)
dtGrdViewGrid.DataSource = table4DataSource;
and then use:
(dtGrdViewGrid.DataSource as DataTable).DefaultView.RowFilter = "col00 = '" + textBoxSearch.Text+ "'";
dtGrdViewGrid.Refresh();
You can even put this piece of code within your textbox_textchange
event and your filtered values will be showing as you write.
If you want to circumvent this problem you could also use the shelve. Then you would create files that would be the size of your machines capacity to handle, and only put them on the RAM when necessary, basically writing to the HD and pulling the information back in pieces so you can process it.
Create binary file and check if information is already in it if yes make a local variable to hold it else write some data you deem necessary.
Data = shelve.open('File01')
for i in range(0,100):
Matrix_Shelve = 'Matrix' + str(i)
if Matrix_Shelve in Data:
Matrix_local = Data[Matrix_Shelve]
else:
Data[Matrix_Selve] = 'somenthingforlater'
Hope it doesn't sound too arcaic.
Avoid the for loopfor XY in xy:
Instead read up how the numpy arrays are indexed and handled.
Also try and avoid .txt files if you are dealing with matrices. Try to use .csv or .npy files, and use Pandas dataframework to load them just for clarity.
First of all, the best answer for the literal question is
Hash === @some_var
But the question really should have been answered by showing how to do duck-typing here. That depends a bit on what kind of duck you need.
@some_var.respond_to?(:each_pair)
or
@some_var.respond_to?(:has_key?)
or even
@some_var.respond_to?(:to_hash)
may be right depending on the application.
You could use setInterval
for this.
<script type="text/javascript">
function myFunction () {
console.log('Executed!');
}
var interval = setInterval(function () { myFunction(); }, 60000);
</script>
Disable the timer by setting clearInterval(interval)
.

Since the event object "evt" is not passed from the parameter, is it still possible to obtain this object?
No, not reliably. IE and some other browsers make it available as window.event
(not $(window.event)
), but that's non-standard and not supported by all browsers (famously, Firefox does not).
You're better off passing the event object into the function:
<a href="#" onclick="myFunc(event, 1,2,3)">click</a>
That works even on non-IE browsers because they execute the code in a context that has an event
variable (and works on IE because event
resolves to window.event
). I've tried it in IE6+, Firefox, Chrome, Safari, and Opera. Example: http://jsbin.com/iwifu4
But your best bet is to use modern event handling:
HTML:
<a href="#">click</a>
JavaScript using jQuery (since you're using jQuery):
$("selector_for_the_anchor").click(function(event) {
// Call `myFunc`
myFunc(1, 2, 3);
// Use `event` here at the event handler level, for instance
event.stopPropagation();
});
...or if you really want to pass event
into myFunc
:
$("selector_for_the_anchor").click(function(event) {
myFunc(event, 1, 2, 3);
});
The selector can be anything that identifies the anchor. You have a very rich set to choose from (nearly all of CSS3, plus some). You could add an id
or class
to the anchor, but again, you have other choices. If you can use where it is in the document rather than adding something artificial, great.
So that you don't mess up other permissions already on the file, use the flag +
, such as via
sudo chmod -R o+rw /var/www
You can use dirname
:
os.path.dirname(path)
Return the directory name of pathname path. This is the first element of the pair returned by passing path to the function split().
And given the full path, then you can split normally to get the last portion of the path. For example, by using basename
:
os.path.basename(path)
Return the base name of pathname path. This is the second element of the pair returned by passing path to the function split(). Note that the result of this function is different from the Unix basename program; where basename for '/foo/bar/' returns 'bar', the basename() function returns an empty string ('').
All together:
>>> import os
>>> path=os.path.dirname("C:/folder1/folder2/filename.xml")
>>> path
'C:/folder1/folder2'
>>> os.path.basename(path)
'folder2'
Sometimes sorting the whole data ahead is very time consuming. We can groupby first and doing topk for each group:
g = df.groupby(['id']).apply(lambda x: x.nlargest(topk,['value'])).reset_index(drop=True)

The minimal-ui viewport property is no longer supported in iOS 8. However, the minimal-ui itself is not gone. User can enter the minimal-ui with a "touch-drag down" gesture.
There are several pre-conditions and obstacles to manage the view state, e.g. for minimal-ui to work, there has to be enough content to enable user to scroll; for minimal-ui to persist, window scroll must be offset on page load and after orientation change. However, there is no way of calculating the dimensions of the minimal-ui using the screen
variable, and thus no way of telling when user is in the minimal-ui in advance.
These observations is a result of research as part of developing Brim – view manager for iOS 8. The end implementation works in the following way:
When page is loaded, Brim will create a treadmill element. Treadmill element is used to give user space to scroll. Presence of the treadmill element ensures that user can enter the minimal-ui view and that it continues to persist if user reloads the page or changes device orientation. It is invisible to the user the entire time. This element has ID
brim-treadmill
.Upon loading the page or after changing the orientation, Brim is using Scream to detect if page is in the minimal-ui view (page that has been previously in minimal-ui and has been reloaded will remain in the minimal-ui if content height is greater than the viewport height).
When page is in the minimal-ui, Brim will disable scrolling of the document (it does this in a safe way that does not affect the contents of the main element). Disabling document scrolling prevents accidentally leaving the minimal-ui when scrolling upwards. As per the original iOS 7.1 spec, tapping the top bar brings back the rest of the chrome.
The end result looks like this:
For the sake of documentation, and in case you prefer to write your own implementation, it is worth noting that you cannot use Scream to detect if device is in minimal-ui straight after the orientationchange event because window
dimensions do not reflect the new orientation until the rotation animation has ended. You have to attach a listener to the orientationchangeend event.
Scream and orientationchangeend have been developed as part of this project.
I'm using contentEditable
to allow rich text editing in my app. I don't know how it slips through, but when an image is inserted, and then resized (by dragging the anchors on its side), it generates something like this:
<img style="width:55px;height:55px" width="100" height="100" src="pic.gif" border=0/>
(subsequent testing shown that inserted images did not contain this "rogue" style attr+param).
When rendered by the browser (IE7), the width and height in the style overrides the img width/height param (so the image is shown like how I wanted it.. resized to 55px x 55px. So everything went well so it seems.
When I output the page to a ms-word document via setting the mime type application/msword or pasting the browser rendering to msword document, all the images reverted back to its default size. I finally found out that msword is discarding the style and using the img width and height tag (which has the value of the original image size).
Took me a while to found this out. Anyway... I've coded a javascript function to traverse all tags and "transferring" the img style.width and style.height values into the img.width and img.height, then clearing both the values in style, before I proceed saving this piece of html/richtext data into the database.
cheers.
opps.. my answer is.. no. leave both attributes directly under img, rather than style.
This worked for me:
ul.dropdown-menu > li {
max-width: 144px;
}
in Chromium and Firefox.
A simple map builder is trivial to write:
public class Maps {
public static <Q,W> MapWrapper<Q,W> map(Q q, W w) {
return new MapWrapper<Q, W>(q, w);
}
public static final class MapWrapper<Q,W> {
private final HashMap<Q,W> map;
public MapWrapper(Q q, W w) {
map = new HashMap<Q, W>();
map.put(q, w);
}
public MapWrapper<Q,W> map(Q q, W w) {
map.put(q, w);
return this;
}
public Map<Q,W> getMap() {
return map;
}
}
public static void main(String[] args) {
Map<String, Integer> map = Maps.map("one", 1).map("two", 2).map("three", 3).getMap();
for (Map.Entry<String, Integer> entry : map.entrySet()) {
System.out.println(entry.getKey() + " = " + entry.getValue());
}
}
}
Server-side functions are on the server-side, client-side functions reside on the client.
What you can do is you have to set hidden form variable and submit the form, then on page use Page_Load
handler you can access value of variable and call the server method.
For sending the output to another file (I'm leaving out error checking to focus on the important details):
if (fork() == 0)
{
// child
int fd = open(file, O_RDWR | O_CREAT, S_IRUSR | S_IWUSR);
dup2(fd, 1); // make stdout go to file
dup2(fd, 2); // make stderr go to file - you may choose to not do this
// or perhaps send stderr to another file
close(fd); // fd no longer needed - the dup'ed handles are sufficient
exec(...);
}
For sending the output to a pipe so you can then read the output into a buffer:
int pipefd[2];
pipe(pipefd);
if (fork() == 0)
{
close(pipefd[0]); // close reading end in the child
dup2(pipefd[1], 1); // send stdout to the pipe
dup2(pipefd[1], 2); // send stderr to the pipe
close(pipefd[1]); // this descriptor is no longer needed
exec(...);
}
else
{
// parent
char buffer[1024];
close(pipefd[1]); // close the write end of the pipe in the parent
while (read(pipefd[0], buffer, sizeof(buffer)) != 0)
{
}
}
Depending on what listeners you attach, trace output can go to the debug window, the console, a file, database, or all at once. The possibilities are literally endless, as implementing your own TraceListener is extremely simple.
Below, I have written an answer for n
equals to 5, but you can apply same approach to draw DFAs for any value of n
and 'any positional number system' e.g binary, ternary...
First lean the term 'Complete DFA', A DFA defined on complete domain in d:Q × S?Q is called 'Complete DFA'. In other words we can say; in transition diagram of complete DFA there is no missing edge (e.g. from each state in Q there is one outgoing edge present for every language symbol in S). Note: Sometime we define partial DFA as d ? Q × S?Q (Read: How does “d:Q × S?Q” read in the definition of a DFA).
Step-1: When you divide a number ? by n
then reminder can be either 0, 1, ..., (n - 2) or (n - 1). If remainder is 0
that means ? is divisible by n
otherwise not. So, in my DFA there will be a state qr that would be corresponding to a remainder value r
, where 0 <= r <= (n - 1)
, and total number of states in DFA is n
.
After processing a number string ? over S, the end state is qr implies that ? % n => r (% reminder operator).
In any automata, the purpose of a state is like memory element. A state in an atomata stores some information like fan's switch that can tell whether the fan is in 'off' or in 'on' state. For n = 5, five states in DFA corresponding to five reminder information as follows:
Using above information, we can start drawing transition diagram TD of five states as follows:
Figure-1
So, 5 states for 5 remainder values. After processing a string ? if end-state becomes q0 that means decimal equivalent of input string is divisible by 5. In above figure q0 is marked final state as two concentric circle.
Additionally, I have defined a transition rule d:(q0, 0)?q0 as a self loop for symbol '0'
at state q0, this is because decimal equivalent of any string consist of only '0'
is 0 and 0 is a divisible by n
.
Step-2: TD above is incomplete; and can only process strings of '0'
s. Now add some more edges so that it can process subsequent number's strings. Check table below, shows new transition rules those can be added next step:
+-------------------------------------+ ¦Number¦Binary¦Remainder(%5)¦End-state¦ +------+------+-------------+---------¦ ¦One ¦1 ¦1 ¦q1 ¦ +------+------+-------------+---------¦ ¦Two ¦10 ¦2 ¦q2 ¦ +------+------+-------------+---------¦ ¦Three ¦11 ¦3 ¦q3 ¦ +------+------+-------------+---------¦ ¦Four ¦100 ¦4 ¦q4 ¦ +-------------------------------------+
'1'
there should be a transition rule d:(q0, 1)?q1 '10'
, end-state should be q2, and to process '10'
, we just need to add one more transition rule d:(q1, 0)?q2'11'
, end-state is q3, and we need to add a transition rule d:(q1, 1)?q3'100'
, end-state is q4. TD already processes prefix string '10'
and we just need to add a new transition rule d:(q2, 0)?q4Figure-2
Step-3: Five = 101
Above transition diagram in figure-2 is still incomplete and there are many missing edges, for an example no transition is defined for d:(q2, 1)-?. And the rule should be present to process strings like '101'
.
Because '101'
= 5 is divisible by 5, and to accept '101'
I will add d:(q2, 1)?q0 in above figure-2.
Path: ?(q0)-1?(q1)-0?(q2)-1?(q0)
with this new rule, transition diagram becomes as follows:
Figure-3
Below in each step I pick next subsequent binary number to add a missing edge until I get TD as a 'complete DFA'.
Step-4: Six = 110.
We can process '11'
in present TD in figure-3 as: ?(q0)-11?(q3) -0?(?). Because 6 % 5 = 1 this means to add one rule d:(q3, 0)?q1.

Figure-12
Total number of edges in transition diagram figure-12 are 15 = Q × S = 5 * 3 (a complete DFA). And this DFA can accept all strings consist over {0, 1, 2} those decimal equivalent is divisible by 5.
If you notice at each step, in table there are three entries because at each step I add all possible outgoing edge from a state to make a complete DFA (and I add an edge so that qr state gets for remainder is r
)!
To add further, remember union of two regular languages are also a regular. If you need to design a DFA that accepts binary strings those decimal equivalent is either divisible by 3 or 5, then draw two separate DFAs for divisible by 3 and 5 then union both DFAs to construct target DFA (for 1 <= n <= 10 your have to union 10 DFAs).
If you are asked to draw DFA that accepts binary strings such that decimal equivalent is divisible by 5 and 3 both then you are looking for DFA of divisible by 15 ( but what about 6 and 8?).
Note: DFAs drawn with this technique will be minimized DFA only when there is no common factor between number n
and base e.g. there is no between 5 and 2 in first example, or between 5 and 3 in second example, hence both DFAs constructed above are minimized DFAs. If you are interested to read further about possible mini states for number n
and base b
read paper: Divisibility and State Complexity.
below I have added a Python script, I written it for fun while learning Python library pygraphviz. I am adding it I hope it can be helpful for someone in someway.
So we can apply above trick to draw DFA to recognize number strings in any base 'b'
those are divisible a given number 'n'
. In that DFA total number of states will be n
(for n
remainders) and number of edges should be equal to 'b' * 'n' — that is complete DFA: 'b' = number of symbols in language of DFA and 'n' = number of states.
Using above trick, below I have written a Python Script to Draw DFA for input base
and number
. In script, function divided_by_N
populates DFA's transition rules in base * number
steps. In each step-num, I convert num
into number string num_s
using function baseN()
. To avoid processing each number string, I have used a temporary data-structure lookup_table
. In each step, end-state for number string num_s
is evaluated and stored in lookup_table
to use in next step.
For transition graph of DFA, I have written a function draw_transition_graph
using Pygraphviz library (very easy to use). To use this script you need to install graphviz
. To add colorful edges in transition diagram, I randomly generates color codes for each symbol get_color_dict
function.

In C++ you can access fields or methods, using different operators, depending on it's type:
Note that :: should be used with a class name rather than a class instance, since static fields or methods are common to all instances of a class.
class AClass{
public:
static int static_field;
int instance_field;
static void static_method();
void method();
};
then you access this way:
AClass instance;
AClass *pointer = new AClass();
instance.instance_field; //access instance_field through a reference to AClass
instance.method();
pointer->instance_field; //access instance_field through a pointer to AClass
pointer->method();
AClass::static_field;
AClass::static_method();
Bas Brekelmans's answer is very elegant in its simplicity. But, I found that for an actual application a little more is needed such as:
The class here handles these limitations: http://www.codeproject.com/Articles/31315/Getting-User-Input-With-Dialogs-Part-1
I just downloaded source and copied InputBox.cs into my project.
Surprised there isn't something even better though... My only real complaint is it caption text doesn't support newlines in it since it uses a label control.
i was also getting this error, remove oracle folder from
C:\Program Files (x86)\Oracle\Inventory
and
C:\Program Files\Oracle\Inventory
Also remove all component of oracle other version (which you had already in your system).
Go to services and remove all oracle component and delete old client from
C:\app\username\product\11.2.0\client_1\
You can have more than one statement when still return:
[]() -> your_type {return (
your_statement,
even_more_statement = just_add_comma,
return_value);}
You can easily store a lat/lon decimal number in an unsigned integer field, instead of splitting them up in a integer and decimal part and storing those separately as somewhat suggested here using the following conversion algorithm:
as a stored mysql function:
CREATE DEFINER=`r`@`l` FUNCTION `PositionSmallToFloat`(s INT)
RETURNS decimal(10,7)
DETERMINISTIC
RETURN if( ((s > 0) && (s >> 31)) , (-(0x7FFFFFFF -
(s & 0x7FFFFFFF))) / 600000, s / 600000)
and back
CREATE DEFINER=`r`@`l` FUNCTION `PositionFloatToSmall`(s DECIMAL(10,7))
RETURNS int(10)
DETERMINISTIC
RETURN s * 600000
That needs to be stored in an unsigned int(10), this works in mysql as well as in sqlite which is typeless.
through experience, I find that this works really fast, if all you need to to is store coordinates and retrieve those to do some math with.
in php those 2 functions look like
function LatitudeSmallToFloat($LatitudeSmall){
if(($LatitudeSmall>0)&&($LatitudeSmall>>31))
$LatitudeSmall=-(0x7FFFFFFF-($LatitudeSmall&0x7FFFFFFF))-1;
return (float)$LatitudeSmall/(float)600000;
}
and back again:
function LatitudeFloatToSmall($LatitudeFloat){
$Latitude=round((float)$LatitudeFloat*(float)600000);
if($Latitude<0) $Latitude+=0xFFFFFFFF;
return $Latitude;
}
This has some added advantage as well in term of creating for example memcached unique keys with integers. (ex: to cache a geocode result). Hope this adds value to the discussion.
Another application could be when you are without GIS extensions and simply want to keep a few million of those lat/lon pairs, you can use partitions on those fields in mysql to benefit from the fact they are integers:
Create Table: CREATE TABLE `Locations` (
`lat` int(10) unsigned NOT NULL,
`lon` int(10) unsigned NOT NULL,
`location` text,
PRIMARY KEY (`lat`,`lon`) USING BTREE,
KEY `index_location` (`locationText`(30))
) ENGINE=InnoDB DEFAULT CHARSET=utf8
/*!50100 PARTITION BY KEY ()
PARTITIONS 100 */
Try to use this , it works perfectly for me
//
varb = new List<object>();
// Example
varb.Add(new[] { float.Parse(GridView1.Rows[1].Cells[2].Text )});
// JSON + Serializ
public string Json()
{
return (new JavaScriptSerializer()).Serialize(varb);
}
// Jquery SIDE
var datasets = {
"Products": {
label: "Products",
data: <%= getJson() %>
}
Have a look at the strcat function.
In particular, you could try this:
const char* name = "hello";
const char* extension = ".txt";
char* name_with_extension;
name_with_extension = malloc(strlen(name)+1+4); /* make space for the new string (should check the return value ...) */
strcpy(name_with_extension, name); /* copy name into the new var */
strcat(name_with_extension, extension); /* add the extension */
public static class Helper
{
public static string AsJsonList<T>(List<T> tt)
{
return new JavaScriptSerializer().Serialize(tt);
}
public static string AsJson<T>(T t)
{
return new JavaScriptSerializer().Serialize(t);
}
public static List<T> AsObjectList<T>(string tt)
{
return new JavaScriptSerializer().Deserialize<List<T>>(tt);
}
public static T AsObject<T>(string t)
{
return new JavaScriptSerializer().Deserialize<T>(t);
}
}
Couldn't your query just be written as:
SELECT u1.name as UserName from Message m1, User u1
WHERE u1.uid = m1.UserFromID GROUP BY u1.name HAVING count(m1.UserFromId)>3
That should also help with the known speed issues with subqueries in MySQL
If you want to find the folder in a platform independent way, you should query the registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Cache
You need to call tf.global_variables_initializer()
on you session, like

sess.run(init)

onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).
Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.
In your onCreate:
yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar);
yourSeekBar.setOnSeekBarChangeListener(new yourListener());
Your listener:
private class yourListener implements SeekBar.OnSeekBarChangeListener {
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// Log the progress
Log.d("DEBUG", "Progress is: "+progress);
//set textView's text
yourTextView.setText(""+progress);
}
public void onStartTrackingTouch(SeekBar seekBar) {}
public void onStopTrackingTouch(SeekBar seekBar) {}
}
Please share some code and the Log results for furter help.

For CentOS 6, PHP 5.3.3 is the latest version of PHP available through the official CentOS package repository. Keep in mind, even though PHP 5.3.3 was released July 22, 2010, the official CentOS 6 PHP package was updated November 24, 2013. Why? Critical bug fixes are backported. See this question for more information: "Why are outdated packages installed by yum on CentOS? (specifically PHP 5.1) How to fix?"
If you'd like to use a more recent version of PHP, Les RPM de Remi offers CentOS PHP packages via a repository that you can add to the yum package manager. To add it as a yum repository, follow the site's instructions.
Note: Questions of this variety are probably better suited for Server Fault.
It's been a while, but last time I had something similar:
ROLLBACK TRAN
or trying to
COMMIT
what had allready been done free'd everything up so I was able to clear things out and start again.
you could do so:
<button onclick="location.href='page'">
you could change the action attribute of the form on click the button:
<button class="float-left submit-button" onclick='myFun()'>Home</button>
<script>
myFun(){
$('form').attr('action','new path');
}
</script>
In the bash shell, try cat -v <filename>
. This should display carriage-returns for windows files.
(This worked for me in rxvt via Cygwin on Windows XP).
Editor's note: cat -v
visualizes \r
(CR) chars. as ^M
. Thus, line-ending \r\n
sequences will display as ^M
at the end of each output line. cat -e
will additionally visualize \n
, namely as $
. (cat -et
will additionally visualize tab chars. as ^I
.)
They are both basically same, there is no difference in performance of any sort, the recommended one however is the first case as it is more readable.
int[] array = new int[10];
FROM JLS:
The [] may appear as part of the type at the beginning of the declaration, or as part of the declarator for a particular variable, or both.
I had the same problem. A simple 'Clean Solution' in VS cleared the error, but it was a temporary solution.
You can create an array containing the numbers 0 to 5 and shuffle those. Then use the result as a mapping of "oldIndex -> newIndex" and apply this mapping to both your original arrays.
You can also give weight separately like this ,
LayoutParams lp1 = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
lp1.weight=1;
I'm particularly fond of this date picker built for Mootools: http://electricprism.com/aeron/calendar/
It's lovely right out of the box.
This can be done without terminal, directly from IDE. Netbeans, for example.

using the above looping leads to Exception

To avoid this Follow the below code to remove all the elements from SparseArray
using normal loops

for(int i=0; i<sparseArray.size(); i++){
int key = sparseArray.keyAt(i);
Log.d("Element at "+key, " is "+sparseArray.get(key));

The simplest way is to make String
conform to Error
:
extension String: Error {}
Then you can just throw a string:
throw "Some Error"
To make the string itself be the localizedString
of the error you can instead extend LocalizedError
:
extension String: LocalizedError {
public var errorDescription: String? { return self }
}
Similar to the above solutions I used @Input()
in a directive and able to pass multiple arrays of values in the directive.
selector: '[selectorHere]',
@Input() options: any = {};
Input.html
<input selectorHere [options]="selectorArray" />
Array from TS file
selectorArray= {
align: 'left',
prefix: '$',
thousands: ',',
decimal: '.',
precision: 2
};

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("viewController")

Prerequisite
Assign a Storyboard ID to your view controller.
IB > Show the Identity inspector > Identity > Storyboard ID
Swift (legacy)
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("viewController") as? UIViewController
self.navigationController!.pushViewController(vc!, animated: true)
Edit: Swift 2 suggested in a comment by Fred A.
if you want to use without any navigationController you have to use like following :
let Storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = Storyboard.instantiateViewController(withIdentifier: "viewController")
present(vc , animated: true , completion: nil)
They are the same concepts, apart from the NULL value returned.

Satisfies all your requirements if you use the trick told below
/^(\+\d{1,3}[- ]?)?\d{10}$/
^
start of line+
followed by \d+
followed by a
or -
which are optional.0
s do not follow.\d+
10 times.DEMO Added m
ultiline flag in demo to check for all cases
P.S. You really need to specify which language you use so as to use an if
condition something like below:
// true if above regex is satisfied and (&&) it does not (`!`) match `0`s `5` or more times
if(number.match(/^(\+\d{1,3}[- ]?)?\d{10}$/) && ! (number.match(/0{5,}/)) )
you can pull it out of the flow by setting position:absolute
on it, but you'll have different display issues to deal with. Or you can explicitly set the width to > 960.
A Date
object has no format, it is a representation. The date can be presented by a String
with the format you like.
E.g. "yyyy-MM-dd
", "yy-MMM-dd
", "dd-MMM-yy
" and etc.
To acheive this you can get the use of the SimpleDateFormat
Try this,
String inputString = "19/05/2009"; // i.e. (dd/MM/yyyy) format
SimpleDateFormat fromUser = new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat myFormat = new SimpleDateFormat("yyyy-MM-dd");
try {
Date dateFromUser = fromUser.parse(inputString); // Parse it to the exisitng date pattern and return Date type
String dateMyFormat = myFormat.format(dateFromUser); // format it to the date pattern you prefer
System.out.println(dateMyFormat); // outputs : 2009-05-19
} catch (ParseException e) {
e.printStackTrace();
}
This outputs : 2009-05-19
To change the color of button programmatically
Button b1;
//colorAccent is the resource made in the color.xml file , you can change it.
b1.setBackgroundResource(R.color.colorAccent);
You just need to install jaxb har files and include in the classpath. this works in java 11 to 12 latest.
To those who are looking for the fix i made some gist in github hope this help. and the links are provided also.

You can combine attribute selectors this way:
$("[attr1=val][attr2=val]")...
so that an element has to satisfy both conditions. Of course you can use this for more than two. Also, don't do [type=checkbox]
. jQuery has a selector for that, namely :checkbox
so the end result is:
$("input:checkbox[name=ProductCode]")...
Attribute selectors are slow however so the recommended approach is to use ID and class selectors where possible. You could change your markup to:
<input type="checkbox" class="ProductCode" name="ProductCode"value="396P4">
<input type="checkbox" class="ProductCode" name="ProductCode"value="401P4">
<input type="checkbox" class="ProductCode" name="ProductCode"value="F460129">
allowing you to use the much faster selector of:
$("input.ProductCode")...
The simple answer is to turn off async
. But that's the wrong thing to do. The correct answer is to re-think how you write the rest of your code.
Instead of writing this:
function functABC(){
$.ajax({
url: 'myPage.php',
data: {id: id},
success: function(data) {
return data;
}
});
}
function foo () {
var response = functABC();
some_result = bar(response);
// and other stuff and
return some_result;
}
You should write it like this:
function functABC(callback){
$.ajax({
url: 'myPage.php',
data: {id: id},
success: callback
});
}
function foo (callback) {
functABC(function(data){
var response = data;
some_result = bar(response);
// and other stuff and
callback(some_result);
})
}
That is, instead of returning result, pass in code of what needs to be done as callbacks. As I've shown, callbacks can be nested to as many levels as you have function calls.
A quick explanation of why I say it's wrong to turn off async:
Turning off async will freeze the browser while waiting for the ajax call. The user cannot click on anything, cannot scroll and in the worst case, if the user is low on memory, sometimes when the user drags the window off the screen and drags it in again he will see empty spaces because the browser is frozen and cannot redraw. For single threaded browsers like IE7 it's even worse: all websites freeze! Users who experience this may think you site is buggy. If you really don't want to do it asynchronously then just do your processing in the back end and refresh the whole page. It would at least feel not buggy.
==
is the correct operator to compare strings in Go. However, the strings that you read from STDIN with reader.ReadString
do not contain "a"
, but "a\n"
(if you look closely, you'll see the extra line break in your example output).
You can use the strings.TrimRight
function to remove trailing whitespaces from your input:
if strings.TrimRight(input, "\n") == "a" {
// ...

While editing the code (because mild OCD), I noticed that weather is also a list. You should probably consider something like
echo $data[0]->weather[0]->weatherIconUrl[0]->value;
to make sure you are using the weatherIconUrl for the correct date instance.
Assuming Java (JDK + JRE) is installed in your system, do the following steps:
C:>echo %path%
C:\Program Files (x86)\Java\jdk1.6.0_27\bin;%CATALINA_HOME%\bin;
C:>echo %classpath%
C:\Program Files (x86)\Java\jdk1.6.0_27\lib\tools.jar;
C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\lib\servlet-api.jar;
C:>echo %CATALINA_HOME%
C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0;
C:>echo %JAVA_HOME%
C:\Program Files (x86)\Java\jdk1.6.0_27;
Now you can test whether Tomcat is setup correctly, by typing the following commands in your command prompt:
C:/>javap javax.servlet.ServletException
C:/>javap javax.servlet.http.HttpServletRequest
It should show a bunch of classes
Now start Tomcat service by double clicking on 'Tomcat7.exe' under 'C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\bin'.
All you need to do is use size() to get the last value of the Arraylist. For ex. if you ArrayList of integers, then to get last value you will have to
int lastValue = arrList.get(arrList.size()-1);
Remember, elements in an Arraylist can be accessed using index values. Therefore, ArrayLists are generally used to search items.
I was successfully able to detect overlapping regions in images captured from adjacent webcams using the technique presented in this paper. My covariance matrix was composed of Sobel, canny and SUSAN aspect/edge detection outputs, as well as the original greyscale pixels.

Here is a clean, clear JavaScript function. It will escape text such as "a few < many" into "a few < many".
function escapeHtmlEntities (str) {
if (typeof jQuery !== 'undefined') {
// Create an empty div to use as a container,
// then put the raw text in and get the HTML
// equivalent out.
return jQuery('<div/>').text(str).html();
}
// No jQuery, so use string replace.
return str
.replace(/&/g, '&')
.replace(/>/g, '>')
.replace(/</g, '<')
.replace(/"/g, '"')
.replace(/'/g, ''');
}

Here you go:
data = []
table = soup.find('table', attrs={'class':'lineItemsTable'})
table_body = table.find('tbody')
rows = table_body.find_all('tr')
for row in rows:
cols = row.find_all('td')
cols = [ele.text.strip() for ele in cols]
data.append([ele for ele in cols if ele]) # Get rid of empty values

Couple of things to note:
Use the WebClient
class in System.Net
:
var json = new WebClient().DownloadString("url");
Keep in mind that WebClient
is IDisposable
, so you would probably add a using
statement to this in production code. This would look like:
using (WebClient wc = new WebClient())
{
var json = wc.DownloadString("url");
}
The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n
, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n
on input, and conversely on output.
From the C99 standard (the N869 draft document), §7.19.2/2,
A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.
And in §7.19.3/2
Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.
About use of fseek
, in §7.19.9.2/4:
For a text stream, either
offset
shall be zero, oroffset
shall be a value returned by an earlier successful call to theftell
function on a stream associated with the same file andwhence
shall beSEEK_SET
.
About use of ftell
, in §17.19.9.4:
The
ftell
function obtains the current value of the file position indicator for the stream pointed to bystream
. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by thefseek
function for returning the file position indicator for the stream to its position at the time of theftell
call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.
I think that’s the most important, but there are some more details.

I am new to retrofit and I am enjoying it. So here is a simple way to understand it for those that might want to query with more than one query: The ? and & are automatically added for you.
Interface:
public interface IService {
String BASE_URL = "https://api.test.com/";
String API_KEY = "SFSDF24242353434";
@GET("Search") //i.e https://api.test.com/Search?
Call<Products> getProducts(@Query("one") String one, @Query("two") String two,
@Query("key") String key)
}
It will be called this way. Considering you did the rest of the code already.
Call<Results> call = service.productList("Whatever", "here", IService.API_KEY);
For example, when a query is returned, it will look like this.
//-> https://api.test.com/Search?one=Whatever&two=here&key=SFSDF24242353434

Here you can get the date based on the Client Timezone (Browser).
moment(new Date().getTime()).zone(new Date().toString().match(/([-\+][0-9]+)\s/)[1]).format('YYYY-MM-DD HH:mm:ss')
The regex basically gets you the offset value.

Addition to Mark Byers answer :
Sometimes you also want to insert Hardcoded details else there may be Unique constraint fail etc. So use following in such situation where you override some values of the columns.
INSERT INTO matrimony_domain_details (domain, type, logo_path)
SELECT 'www.example.com', type, logo_path
FROM matrimony_domain_details
WHERE id = 367
Here domain value is added by me me in Hardcoded way to get rid from Unique constraint.
I solved this exception by changing the target sdk
version from 19 onwards kitkat version AndroidManifest.xml.
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
Steps I used to resolve it:
your version
Now, you should be able to add to server on right click "Add and Remove".
Note: Additionally, when on clear/run, you get an error for multiple instances, open server.xml and ensure that it contains a single instance of each application and not multiple.
For what you are wanting to do, you should use the enumerated()
method on your Array:
for (index, element) in list.enumerated() {
print("\(index) - \(element)")
}
Set the tagName as an explicit attribute:
for(var i=0,els=document.querySelectorAll('*'); i<els.length;
els[i].setAttribute('tagName',els[i++].tagName) );
I needed this myself, for an XML Document, with Nested Tags ending in _Sequence
. See JaredMcAteer answer for more details.
document.querySelectorAll('[tagName$="_Sequence"]')
I didn't say it would be pretty :)
PS: I would recommend to use tag_name
over tagName, so you do not run into interferences when reading 'computer generated', implicit DOM attributes.
I don't know of any good libraries for this, but whatever you do, make sure that you err in the direction of letting stuff through. I've dealt with systems that wouldn't allow me to use "mpassell" as a username, because it contains "ass" as a substring. That's a great way to alienate users!
DELETE FROM konta WHERE taken <> '';
Instead of checking for Build.VERSION.SDK_INT >= Build.VERSION_CODES.O
as many answers suggest, there is a slightly simpler way -
Add the following line to the application
section of AndroidManifest.xml file as explained in the Set Up a Firebase Cloud Messaging Client App on Android doc:
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="@string/default_notification_channel_id" />
Then add a line with a channel name to the values/strings.xml file:
<string name="default_notification_channel_id">default</string>
After that you will be able to use the new version of NotificationCompat.Builder constructor with 2 parameters (since the old constructor with 1 parameter has been deprecated in Android Oreo):
private void sendNotification(String title, String body) {
Intent i = new Intent(this, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pi = PendingIntent.getActivity(this,
0 /* Request code */,
i,
PendingIntent.FLAG_ONE_SHOT);
Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this,
getString(R.string.default_notification_channel_id))
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(body)
.setAutoCancel(true)
.setSound(sound)
.setContentIntent(pi);
NotificationManager manager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(0, builder.build());
}
You could use Javascript's substring method. For example:
var list = ["bird1", "bird2", "pig1"]
for (var i = 0; i < list.length; i++) {
if (list[i].substring(0,4) == "bird") {
console.log(list[i]);
}
}
Which outputs:
bird1
bird2
Basically, you're checking each item in the array to see if the first four letters are 'bird'. This does assume that 'bird' will always be at the front of the string.
So let's say your getting a pathname from a URL :
Let's say your at bird1?=letsfly - you could use this code to check the URL:
var listOfUrls = [
"bird1?=letsfly",
"bird",
"pigs?=dontfly",
]
for (var i = 0; i < list.length; i++) {
if (listOfUrls[i].substring(0,4) === 'bird') {
// do something
}
}
The above would match the first to URL's, but not the third (not the pig). You could easily swap out url.substring(0,4)
with a regex, or even another javascript method like .contains()
Using the .contains()
method might be a little more secure. You won't need to know which part of the URL 'bird' is at. For instance:
var url = 'www.example.com/bird?=fly'
if (url.contains('bird')) {
// this is true
// do something
}
I solved this issue by doing like that:
insert into my_table(my_field_0, ..., my_field_n) values(my_value_0, ..., my_value_n)
If you want to detect the status of navigation bar wether it is hidden/shown. You can simply use following code to detect -
if self.navigationController?.isNavigationBarHidden{
print("Show navigation bar")
} else {
print("hide navigation bar")
}
You can use your original script to set the variables, but you need to call it the following way (with stand-alone dot):
. ./minientrega.sh
Also there might be an issue with cat | while read
approach. I would recommend to use the approach while read line; do .... done < $FILE
.
Here is a working example:
> cat test.conf
VARIABLE_TMP1=some_value
> cat run_test.sh
#/bin/bash
while read line; do export "$line";
done < test.conf
echo "done"
> . ./run_test.sh
done
> echo $VARIABLE_TMP1
some_value
I know this is a dated question but I have the shortest solution of the ones listed here and thought I would share since I think its easier to understand.
This version does not require any hard coded logic for edge cases such as 4(IV),9(IX),40(XL),900(CM), etc. as the others do. This also means it can handle larger numbers greater than the maximum roman scale could (3999). For example if "T" became a new symbol you could add it to the beginning of the romanLookup object and it would keep the same algorithmic affect; or course assuming the "no more than 3 of the same symbol in a row" rule applies.
I have tested this against a data set from 1-3999 and it works flawlessly.
function convertToRoman(num) {
//create key:value pairs
var romanLookup = {M:1000, D:500, C:100, L:50, X:10, V:5, I:1};
var roman = [];
var romanKeys = Object.keys(romanLookup);
var curValue;
var index;
var count = 1;
for(var numeral in romanLookup){
curValue = romanLookup[numeral];
index = romanKeys.indexOf(numeral);
while(num >= curValue){
if(count < 4){
//push up to 3 of the same numeral
roman.push(numeral);
} else {
//else we had to push four, so we need to convert the numerals
//to the next highest denomination "coloring-up in poker speak"
//Note: We need to check previous index because it might be part of the current number.
//Example:(9) would attempt (VIIII) so we would need to remove the V as well as the I's
//otherwise removing just the last three III would be incorrect, because the swap
//would give us (VIX) instead of the correct answer (IX)
if(roman.indexOf(romanKeys[index - 1]) > -1){
//remove the previous numeral we worked with
//and everything after it since we will replace them
roman.splice(roman.indexOf(romanKeys[index - 1]));
//push the current numeral and the one that appeared two iterations ago;
//think (IX) where we skip (V)
roman.push(romanKeys[index], romanKeys[index - 2]);
} else {
//else Example:(4) would attemt (IIII) so remove three I's and replace with a V
//to get the correct answer of (IV)
//remove the last 3 numerals which are all the same
roman.splice(-3);
//push the current numeral and the one that appeared right before it; think (IV)
roman.push(romanKeys[index], romanKeys[index - 1]);
}
}
//reduce our number by the value we already converted to a numeral
num -= curValue;
count++;
}
count = 1;
}
return roman.join("");
}
convertToRoman(36);
Rob's solution is the right one--use @require
with the jQuery library and be sure to reinstall your script so the directive gets processed.
One thing I think is worth adding is that you can use jQuery normally once you have included it in your script, except for AJAX methods. By default jQuery looks for XMLHttpRequest, which doesn't exist in the Greasemonkey context. I wrote about a workaround where you create a wrapper for GM_xmlhttpRequest (the Greasemonkey version of XHR) and use jQuery's ajaxSetup()
to specify your wrapped version as the default. Once you do this, you can use $.get
and $.post
as usual.
You may also have problems with jQuery's $.getJSON
because it loads JSONP using <script>
tags. This leads to errors because jQuery defines the callback function in the scope of the Greasemonkey window, and the loaded scripts looks for the callback in the scope of the main window. Your best bet is to use $.get
instead and parse the result with JSON.parse()
.
To add to @DennisWilliamson comment above:
@VaibhavBajpai: Try this: response=$(curl --write-out \n%{http_code} --silent --output - servername) - the last line in the result will be the response code
You can then parse the response code from the response using something like the following, where X can signify a regex to mark the end of the response (using a json example here)
X='*\}'
code=$(echo ${response##$X})
See Substring Removal: http://tldp.org/LDP/abs/html/string-manipulation.html
In order to escape single- and double-quotes, you have to double them up:
$value = 'This is a quote, "I said, 'Hi'"';
$value = str_replace( "'", "''", $value );
$value = str_replace( '"', '""', $value );
$query = "INSERT INTO TableName ( TextFieldName ) VALUES ( '$value' ) ";
etc...

In Addition to Lokesh Tiwar's answer
For release builds add the following in the gradle:
android {
defaultConfig{
//Goes here
}
signingConfigs {
release {
storeFile file("PATH TO THE KEY_STORE FILE")
storePassword "PASSWORD"
keyAlias "ALIAS_NAME"
keyPassword "KEY_PASSWORD"
}
}
buildTypes {
release {
zipAlignEnabled true
minifyEnabled false
signingConfig signingConfigs.release
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
Now running the signingReport as in Lokesh's Answer would show the SHA 1 and MD5 keys for the release builds as well.
The getcode() method (Added in python2.6) returns the HTTP status code that was sent with the response, or None if the URL is no HTTP URL.

In my case, after downloading the assembly and adding the reference to the project, I solved this by 'unblocking' the DLL before adding the reference to the project.
Using Windows explorer, browse to the DLL location, right-click on the DLL and then select 'properties'. You'll find an 'unblock' button on one of the tabs and then you can add the reference and the assembly will load correctly.
One advantage you get with the approach mentioned by @Tom is that you don't have to create any constructors in the SomeManager, and hence limiting the clients to instantiate it.
@RunWith(MockitoJUnitRunner.class)
public class SomeManagerTest {
@InjectMocks
private SomeManager someManager;
@Mock
private SomeDependency someDependency; // this will be injected into someManager
//You don't need to instantiate the SomeManager with default contructor at all
//SomeManager someManager = new SomeManager();
//Or SomeManager someManager = new SomeManager(someDependency);
//tests...
}
Whether its a good practice or not depends on your application design.
You can using the socket module to simply check if a port is open or not.
It would look something like this.
import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
print "Port is open"
else:
print "Port is not open"
sock.close()
No, it's the other way around. It's because you use the virtual machine that the Java program gets independend.
The virtual machine is not independent, you have to install one that is specifically made for your type of system. The virtual machine creates an independent platform on top of the operating system.
You can do it without regex
input.Split(new string[] {"key :"},StringSplitOptions.None)[1]
.Split('-')[0]
.Trim();

Almost all answers assume the ID column is ordered (and perhaps auto incremented). There are situations, however, when the ID column is not ordered, hence the ORDER BY statement makes no sense.
The last inserted ID might not always be the highest ID, it is just the last (unique) entry.
One possible solution for such a situation is to create a row id on the fly:
SET @r = 0;
SELECT * FROM (SELECT *, (@r := @r + 1) AS r_id FROM uat3187) AS tmp
ORDER BY r_id DESC LIMIT 1;
HTML is intended for structuring data, not controlling layout. CSS is intended to control layout. You'll also find that many designers frown on using <table>
for layouts for this very same reason.
Use versions:set
from the versions-maven plugin:
mvn versions:set -DnewVersion=2.50.1-SNAPSHOT
It will adjust all pom versions, parent versions and dependency versions in a multi-module project.
If you made a mistake, do
mvn versions:revert
afterwards, or
mvn versions:commit
if you're happy with the results.
Note: this solution assumes that all modules use the aggregate pom as parent pom also, a scenario that was considered standard at the time of this answer. If that is not the case, go for Garret Wilson's answer.
Very simple:
var dt=new Date("2011/11/30");

I made the steps 1, 2, 3 and the 7. and I put the folder with the class files in the project build path (right click, properties, java build path, libraries, add class folder, create new folder, advanced>>, link to folder in the file system, browse,...) then restart eclipse.
you could do something like (below)
var query = from p in context.T1
join q in context.T2
on
new { p.Col1, p.Col2 }
equals
new { q.Col1, q.Col2 }
select new {p...., q......};

r = read
w = write
x = execute (traverse for directories)
Or like this
class Movie
{
public string FilmName { get; set; }
public string Genre { get; set; }
}
...
var listofGenres = new List<string> { "action", "comedy" };
var Movies = new List<Movie> {new Movie {Genre="action", FilmName="Film1"},
new Movie {Genre="comedy", FilmName="Film2"},
new Movie {Genre="comedy", FilmName="Film3"},
new Movie {Genre="tragedy", FilmName="Film4"}};
var movies = Movies.Join(listofGenres, x => x.Genre, y => y, (x, y) => x).ToList();
This is the easy way to handle timestamp insertion
$data = array('created_on' => date('Y-m-d H:i:s'));
You must write
<img src="theSource" style="width:30px;height:30px;" />
Inline styling will always take precedence over CSS styling. The width and height attributes are being overridden by your stylesheet, so you need to switch to this format.
After doing much R&D on this issue I got the Solution,
In my case I am using Service that will run every 2 second and with the runonUIThread, I was wondering the problem was there but not at all. The next issue that I found is that I am using large Image in may App and thats the problem.
I removed the Images and set new Images.
Conclusion :- Look into your code is there any raw file that you are using is of big size.
A possible very simple fix that worked for me. After deleting any database references and connections you find in server/serverobject explorer, right click the App_Data folder (didn't show any objects within the application for me) and select open. Once open put all the database/etc. files in a backup folder or if you have the guts just delete them. Run your application and it should recreate everything from scratch.
Use the PlaceHolder control as a container to store server controls that are dynamically added to the Web page. The PlaceHolder control does not produce any visible output and is used only as a container for other controls on the Web page. You can use the Control.Controls
collection to add, insert, or remove a control in the PlaceHolder control.
The Panel control is a container for other controls. It is especially useful when you want to generate controls programmatically, hide/show a group of controls, or localize a group of controls.
The Direction
property is useful for localizing a Panel control's content to display text for languages that are written from right to left, such as Arabic or Hebrew.
The Panel control provides several properties that allow you to customize the behavior and display of its contents. Use the BackImageUr
l property to display a custom image for the Panel control. Use the ScrollBars
property to specify scroll bars for the control.
Small differences when rendering HTML: a PlaceHolder control will render nothing, but Panel control will render as a <div>
.

Developed this method:
You NEED a table that has an unique value that can be ordered.
If you want rows 10,000 to 25,000 and your Table has 40,000 rows, first you need to get the starting point and total rows:
int start = 40000 - 10000;
int total = 25000 - 10000;
And then pass these by code to the query:
SELECT * FROM
(SELECT * FROM schema.mytable
ORDER BY userId DESC fetch first {start} rows only ) AS mini
ORDER BY mini.userId ASC fetch first {total} rows only

try this
String json="{'abridged_cast':[{'name':'JeffBridges','id':'162655890','characters':['JackPrescott']},{'name':'CharlesGrodin','id':'162662571','characters':['FredWilson']},{'name':'JessicaLange','id':'162653068','characters':['Dwan']},{'name':'JohnRandolph','id':'162691889','characters':['Capt.Ross']},{'name':'ReneAuberjonois','id':'162718328','characters':['Bagley']}]}";
JSONObject jsonResponse;
try {
ArrayList<String> temp = new ArrayList<String>();
jsonResponse = new JSONObject(json);
JSONArray movies = jsonResponse.getJSONArray("abridged_cast");
for(int i=0;i<movies.length();i++){
JSONObject movie = movies.getJSONObject(i);
JSONArray characters = movie.getJSONArray("characters");
for(int j=0;j<characters.length();j++){
temp.add(characters.getString(j));
}
}
Toast.makeText(this, "Json: "+temp, Toast.LENGTH_LONG).show();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
checked it :)
To know the usage of the specific directory in GB's or TB's in linux the command is,
df -h /dir/inner_dir/
or
df -sh /dir/inner_dir/
and to know the usage of the specific directory in bits in linux the command is,
df-k /dir/inner_dir/

Whether to open the URL in a new tab or a new window, is actually controlled by the user's browser preferences. There is no way to override it in JavaScript.
window.open()
behaves differently depending on how it is being used. If it is called as a direct result of a user action, let us say a button click, it should work fine and open a new tab (or window):
const button = document.querySelector('#openTab');
// add click event listener
button.addEventListener('click', () => {
// open a new tab
const tab = window.open('https://attacomsian.com', '_blank');
});
However, if you try to open a new tab from an AJAX request callback, the browser will block it as it was not a direct user action.
To bypass the popup blocker and open a new tab from a callback, here is a little hack:
const button = document.querySelector('#openTab');
// add click event listener
button.addEventListener('click', () => {
// open an empty window
const tab = window.open('about:blank');
// make an API call
fetch('/api/validate')
.then(res => res.json())
.then(json => {
// TODO: do something with JSON response
// update the actual URL
tab.location = 'https://attacomsian.com';
tab.focus();
})
.catch(err => {
// close the empty window
tab.close();
});
});
