Programs & Examples On #Smallcaps

You could always write a simple program in Python or something to create an include file that has simple #define statements with a build number, time, and date. You would then need to run this program before doing a build.

If you like I'll write one and post source here.

If you are lucky, your build tool (IDE or whatever) might have the ability to run an external command, and then you could have the external tool rewrite the include file automatically with each build.

EDIT: Here's a Python program. This writes a file called build_num.h and has an integer build number that starts at 1 and increments each time this program is run; it also writes #define values for the year, month, date, hours, minutes and seconds of the time this program is run. It also has a #define for major and minor parts of the version number, plus the full VERSION and COMPLETE_VERSION that you wanted. (I wasn't sure what you wanted for the date and time numbers, so I went for just concatenated digits from the date and time. You can change this easily.)

Each time you run it, it reads in the build_num.h file, and parses it for the build number; if the build_num.h file does not exist, it starts the build number at 1. Likewise it parses out major and minor version numbers, and if the file does not exist defaults those to version 0.1.

import time

FNAME = "build_num.h"

build_num = None
version_major = None
version_minor = None

DEF_BUILD_NUM = "#define BUILD_NUM "
DEF_VERSION_MAJOR = "#define VERSION_MAJOR "
DEF_VERSION_MINOR = "#define VERSION_MINOR "

def get_int(s_marker, line):
    _, _, s = line.partition(s_marker) # we want the part after the marker
    return int(s)

try:
    with open(FNAME) as f:
        for line in f:
            if DEF_BUILD_NUM in line:
                build_num = get_int(DEF_BUILD_NUM, line)
                build_num += 1
            elif DEF_VERSION_MAJOR in line:
                version_major = get_int(DEF_VERSION_MAJOR, line)
            elif DEF_VERSION_MINOR in line:
                version_minor = get_int(DEF_VERSION_MINOR, line)
except IOError:
    build_num = 1
    version_major = 0
    version_minor = 1

assert None not in (build_num, version_major, version_minor)


with open(FNAME, 'w') as f:
    f.write("#ifndef BUILD_NUM_H\n")
    f.write("#define BUILD_NUM_H\n")
    f.write("\n")
    f.write(DEF_BUILD_NUM + "%d\n" % build_num)
    f.write("\n")
    t = time.localtime()
    f.write("#define BUILD_YEAR %d\n" % t.tm_year)
    f.write("#define BUILD_MONTH %d\n" % t.tm_mon)
    f.write("#define BUILD_DATE %d\n" % t.tm_mday)
    f.write("#define BUILD_HOUR %d\n" % t.tm_hour)
    f.write("#define BUILD_MIN %d\n" % t.tm_min)
    f.write("#define BUILD_SEC %d\n" % t.tm_sec)
    f.write("\n")
    f.write("#define VERSION_MAJOR %d\n" % version_major)
    f.write("#define VERSION_MINOR %d\n" % version_minor)
    f.write("\n")
    f.write("#define VERSION \"%d.%d\"\n" % (version_major, version_minor))
    s = "%d.%d.%04d%02d%02d.%02d%02d%02d" % (version_major, version_minor,
            t.tm_year, t.tm_mon, t.tm_mday, t.tm_hour, t.tm_min, t.tm_sec)
    f.write("#define COMPLETE_VERSION \"%s\"\n" % s)
    f.write("\n")
    f.write("#endif // BUILD_NUM_H\n")

I made all the defines just be integers, but since they are simple integers you can use the standard stringizing tricks to build a string out of them if you like. Also you can trivially extend it to build additional pre-defined strings.

This program should run fine under Python 2.6 or later, including any Python 3.x version. You could run it under an old Python with a few changes, like not using .partition() to parse the string.

After opening the file, list comprehension can do this in one line:

fh=open('filename')
newlist = [line.rstrip() for line in fh.readlines()]
fh.close()

Just remember to close your file afterwards.

1) Create a handler in the fragment that you want to update.

public static Handler sUpdateHandler;

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ...

        sUpdateHandler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                super.handleMessage(msg);
                // call you update method here.
            }
        };
    }

2) In the Activity/Fragment/Dialog, wherever you want the update call to be fired, get the reference to that handler and send a message (telling your fragment to update)

// Check if the fragment is visible by checking if the handler is null or not.
Handler handler = TaskTabCompletedFragment.sUpdateHandler;
if (handler != null) {
    handler.obtainMessage().sendToTarget();
}

<router-view :key="$route.params.slug" />

just use key with your any params its auto reload children..

The Memory Management Programming Guide from the iOS Reference Library has basics of assign, copy, and retain with analogies and examples.

copy Makes a copy of an object, and returns it with retain count of 1. If you copy an object, you own the copy. This applies to any method that contains the word copy where “copy” refers to the object being returned.

retain Increases the retain count of an object by 1. Takes ownership of an object.

release Decreases the retain count of an object by 1. Relinquishes ownership of an object.

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download

Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.

JDK vs OpenJDK

You need not store the diff in a 3rd file and then read from in. Instead you make use of the Runtime.exec

Process p = Runtime.getRuntime().exec("diff fileA fileB");
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
while ((s = stdInput.readLine()) != null) {
        System.out.println(s);
}

The slowdown is not necessarily the same with any compiler.

I haven't used Delphi or Kylix but back in the MS-DOS days, a Turbo Pascal program would compile almost instantaneously, while the equivalent Turbo C++ program would just crawl.

The two main differences were a very strong module system and a syntax that allowed single-pass compilation.

It's certainly possible that compilation speed just hasn't been a priority for C++ compiler developers, but there are also some inherent complications in the C/C++ syntax that make it more difficult to process. (I'm not an expert on C, but Walter Bright is, and after building various commercial C/C++ compilers, he created the D language. One of his changes was to enforce a context-free grammar to make the language easier to parse.)

Also, you'll notice that generally Makefiles are set up so that every file is compiled separately in C, so if 10 source files all use the same include file, that include file is processed 10 times.

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null, though, otherwise it acts like new DateTime() - I really don't like that.

PHP 5.x.x does not support overloading this is why PHP is not fully OOP.

I hope this still helps someone as many people might get to this article. If you need a computed column, why not just expose your desired columns in a view ? Don't just save data or overload the performance with triggers... simply expose the data you need already formatted/calculated in a view.

Hope this helps...

Another way to address this annoyance is to create your own CSS class that does not set the !important at the end of rule, like this:

.hideMe {
    display: none;
}

and used like so :

<div id="header-mask" class="hideMe"></div>

and now jQuery hiding works

$('#header-mask').show();

self.paddingView.layer.masksToBounds = false
self.paddingView.layer.shadowOffset = CGSize(width: -15, height: 10)
self.paddingView.layer.shadowRadius = 5
self.paddingView.layer.shadowOpacity = 0.5

In case above-accepted answer did not work, try below solution. You can use it for port 8080 or for any other ports.

sudo lsof -i tcp:3000 

Replace 3000 with whichever port you want. Run below command to kill that process.

sudo kill -9 PID

PID is process ID you want to kill.

Below is the output of commands on mac Terminal.

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

Using Pygrok, you can define abstracted extensions to the Regular Expression syntax.

The custom patterns can be included in your regex in the format %{PATTERN_NAME}.

You can also create a label for that pattern, by separating with a colon: %s{PATTERN_NAME:matched_string}. If the pattern matches, the value will be returned as part of the resulting dictionary (e.g. result.get('matched_string'))

For example:

from pygrok import Grok

input_string = 'monkey 2010-07-10 love banana'
date_pattern = '%{YEAR:year}-%{MONTHNUM:month}-%{MONTHDAY:day}'

grok = Grok(date_pattern)
print(grok.match(input_string))

The resulting value will be a dictionary:

{'month': '07', 'day': '10', 'year': '2010'}

If the date_pattern does not exist in the input_string, the return value will be None. By contrast, if your pattern does not have any labels, it will return an empty dictionary {}

I am not sure what the problem is, but I am pretty sure this will fix it.

for (i=0; i<arrChecks.length; i++)
    {
        var attribute = arrChecks[i].getAttribute("xid")
        if (attribute == elementName)
        {
            if (arrChecks[i].checked == 0)  
            {
                arrChecks[i].checked = 1;
            } else {
                arrChecks[i].checked = 0;
            }

        } else {
            arrChecks[i].checked = 0;
        }
    }

Sometimes you inherit brittle code that is already expecting magic values in a lot of places. Everyone is correct, you should use NULL if possible. However, as a shortcut to make sure every reference to that value is the same, I like to put "constants" (for lack of a better name) in SQL in a scaler function and then call that function when I need the value. That way if I ever want to update them all to be something else, I can do so easily. Or if I want to change the default value moving forward, I only have one place to update it.

The following code creates the function and a table using it for the default DateTime value. Then inserts and select from the table without specifying the value for Modified. Then cleans up after itself. I hope this helps.

-- CREATE FUNCTION
CREATE FUNCTION dbo.DateTime_MinValue ( )
RETURNS DATETIME
AS 
    BEGIN
        DECLARE @dateTime_min DATETIME ;
        SET @dateTime_min = '1/1/1753 12:00:00 AM'
        RETURN @dateTime_min ;
    END ;
GO


-- CREATE TABLE USING FUNCTION FOR DEFAULT
CREATE TABLE TestTable
(
  TestTableId INT IDENTITY(1, 1)
                  PRIMARY KEY CLUSTERED ,
  Value VARCHAR(50) ,
  Modified DATETIME DEFAULT dbo.DateTime_MinValue()
) ;


-- INSERT VALUE INTO TABLE
INSERT  INTO TestTable
        ( Value )
VALUES  ( 'Value' ) ;


-- SELECT FROM TABLE
SELECT  TestTableId ,
        VALUE ,
        Modified
FROM    TestTable ;


-- CLEANUP YOUR DB
DROP TABLE TestTable ;
DROP FUNCTION dbo.DateTime_MinValue ;

In SQL Server you can do this:

SELECT *
FROM (
SELECT ROW_NUMBER()
OVER(PARTITION BY customer
ORDER BY total DESC) AS StRank, *
FROM Purchases) n
WHERE StRank = 1

Explaination:Here Group by is done on the basis of customer and then order it by total then each such group is given serial number as StRank and we are taking out first 1 customer whose StRank is 1

@John Woo's accepted answer has some caveats which you should be aware of:

1. Default language setting of a session is controlled from default language setting of the user login instead which you have used to create the session. SQL Server instance level setting doesn't affect the default language of the session.
2. Changing default language setting at SQL Server instance level doesn't affects the default language setting of the existing SQL Server logins. It is meant to be inherited only by the new user logins that you create after changing the instance level setting.

So, there is an intermediate level between your SQL Server instance and the session which you can use to control the default language setting for session - login level.

SQL Server Instance level setting -> User login level setting -> Query Session level setting

This can help you in case you want to set default language of all new sessions belonging to some specific user only.

Simply change the default language setting of the target user login as per this link and you are all set. You can also do it from SQL Server Management Studio (SSMS) UI. Below you can see the default language setting in properties window of sa user in SQL Server:

Note: Also, it is important to know that changing the setting doesn't affect the default language of already active sessions from that user login. It will affect only the new sessions created after changing the setting.

After trying most of the solutions posted here, none of which worked, it turned out to be the parental controls on our home network. Turning these parental controls off solved the problem.

According to Fixture finalization / executing teardown code, the current best practice for setup and teardown is to use yield instead of return:

import pytest

@pytest.fixture()
def resource():
    print("setup")
    yield "resource"
    print("teardown")

class TestResource:
    def test_that_depends_on_resource(self, resource):
        print("testing {}".format(resource))

Running it results in

$ py.test --capture=no pytest_yield.py
=== test session starts ===
platform darwin -- Python 2.7.10, pytest-3.0.2, py-1.4.31, pluggy-0.3.1
collected 1 items

pytest_yield.py setup
testing resource
.teardown


=== 1 passed in 0.01 seconds ===

Another way to write teardown code is by accepting a request-context object into your fixture function and calling its request.addfinalizer method with a function that performs the teardown one or multiple times:

import pytest

@pytest.fixture()
def resource(request):
    print("setup")

    def teardown():
        print("teardown")
    request.addfinalizer(teardown)
    
    return "resource"

class TestResource:
    def test_that_depends_on_resource(self, resource):
        print("testing {}".format(resource))

I managed to do it by using the following code.

@Html.TextBoxFor(model => model.EndTime, new { type = "time" })

You could always try doing a ulimit -n 2048. This will only reset the limit for your current shell and the number you specify must not exceed the hard limit

Each operating system has a different hard limit setup in a configuration file. For instance, the hard open file limit on Solaris can be set on boot from /etc/system.

set rlim_fd_max = 166384
set rlim_fd_cur = 8192

On OS X, this same data must be set in /etc/sysctl.conf.

kern.maxfilesperproc=166384
kern.maxfiles=8192

Under Linux, these settings are often in /etc/security/limits.conf.

There are two kinds of limits:

• soft limits are simply the currently enforced limits
• hard limits mark the maximum value which cannot be exceeded by setting a soft limit

Soft limits could be set by any user while hard limits are changeable only by root. Limits are a property of a process. They are inherited when a child process is created so system-wide limits should be set during the system initialization in init scripts and user limits should be set during user login for example by using pam_limits.

There are often defaults set when the machine boots. So, even though you may reset your ulimit in an individual shell, you may find that it resets back to the previous value on reboot. You may want to grep your boot scripts for the existence ulimit commands if you want to change the default.

And a PHP example, multiple matching lines will be displayed:

<?php
$file = 'somefile.txt';
$searchfor = 'name';

// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');

// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
// escape special characters in the query
$pattern = preg_quote($searchfor, '/');
// finalise the regular expression, matching the whole line
$pattern = "/^.*$pattern.*\$/m";
// search, and store all matching occurences in $matches
if(preg_match_all($pattern, $contents, $matches)){
   echo "Found matches:\n";
   echo implode("\n", $matches[0]);
}
else{
   echo "No matches found";
}

Use ApacheCommonUtils to generate a random long within a given range, and then create Date out of that long.

Example:

import org.apache.commons.math.random.RandomData;

import org.apache.commons.math.random.RandomDataImpl;

public Date nextDate(Date min, Date max) {

RandomData randomData = new RandomDataImpl();

return new Date(randomData.nextLong(min.getTime(), max.getTime()));

}

You are using the incorrect overload of ActionLink. Try this

<%= Html.ActionLink("Create New Part", "CreateParts", "PartList", new { parentPartId = 0 }, null)%>

str.replace is the wrong function for what you want to do (apart from it being used incorrectly). You want to replace any character of a set with a space, not the whole set with a single space (the latter is what replace does). You can use translate like this:

removeSpecialChars = z.translate ({ord(c): " " for c in "!@#$%^&*()[]{};:,./<>?\|`~-=_+"})

This creates a mapping which maps every character in your list of special characters to a space, then calls translate() on the string, replacing every single character in the set of special characters with a space.

The GNU assembler (gas) and NASM are both good choices. However, they have some differences, the big one being the order you put operations and their operands.

gas uses AT&T syntax (guide: https://stackoverflow.com/tags/att/info):

mnemonic    source, destination

nasm uses Intel style (guide: https://stackoverflow.com/tags/intel-syntax/info):

mnemonic    destination, source

Either one will probably do what you need. GAS also has an Intel-syntax mode, which is a lot like MASM, not NASM.

For me I had issues with history and location... As the accepted answer using window before history and location (i.e) window.history and window.location solved mine

Starting with ggplot2 2.2.0 you can add a secondary axis like this (taken from the ggplot2 2.2.0 announcement):

ggplot(mpg, aes(displ, hwy)) + 
  geom_point() + 
  scale_y_continuous(
    "mpg (US)", 
    sec.axis = sec_axis(~ . * 1.20, name = "mpg (UK)")
  )

You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.

$("button").click(function() {
    var $btn = $(this);
    $btn.button('loading');
    // simulating a timeout
    setTimeout(function () {
        $btn.button('reset');
    }, 1000);
});

Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.

Delete all documents from a collection in cmd:

In advance of my questions being answered, this is how I'd go about it:

Minimize the number of statements and the work they do issued in relative terms.

All scenarios assume you have a table of IDs (PURGE_IDS) to delete from TABLE_1, TABLE_2, etc.

Consider Using CREATE TABLE AS SELECT for really large deletes

If there's no concurrent activity, and you're deleting 30+ % of the rows in one or more of the tables, don't delete; perform a create table as select with the rows you wish to keep, and swap the new table out for the old table. INSERT /*+ APPEND */ ... NOLOGGING is surprisingly cheap if you can afford it. Even if you do have some concurrent activity, you may be able to use Online Table Redefinition to rebuild the table in-place.

Don't run DELETE statements you know won't delete any rows

If an ID value exists in at most one of the six tables, then keep track of which IDs you've deleted - and don't try to delete those IDs from any of the other tables.

CREATE TABLE TABLE1_PURGE NOLOGGING
AS 
SELECT ID FROM PURGE_IDS INNER JOIN TABLE_1 ON PURGE_IDS.ID = TABLE_1.ID;

DELETE FROM TABLE1 WHERE ID IN (SELECT ID FROM TABLE1_PURGE);

DELETE FROM PURGE_IDS WHERE ID IN (SELECT ID FROM TABLE1_PURGE);

DROP TABLE TABLE1_PURGE;

and repeat.

Manage Concurrency if you have to

Another way is to use PL/SQL looping over the tables, issuing a rowcount-limited delete statement. This is most likely appropriate if there's significant insert/update/delete concurrent load against the tables you're running the deletes against.

declare
  l_sql varchar2(4000);
begin
  for i in (select table_name from all_tables 
             where table_name in ('TABLE_1', 'TABLE_2', ...)
             order by table_name);
  loop
    l_sql := 'delete from ' || i.table_name || 
             ' where id in (select id from purge_ids) ' || 
             '   and rownum <= 1000000';
    loop
      commit;
      execute immediate l_sql;
      exit when sql%rowcount <> 1000000;  -- if we delete less than 1,000,000
    end loop;                             -- no more rows need to be deleted!
  end loop;
  commit;
end;

You can plot multiple subplots of multiple pandas data frames using matplotlib with a simple trick of making a list of all data frame. Then using the for loop for plotting subplots.

Working code:

import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
# dataframe sample data
df1 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df2 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df3 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df4 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df5 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df6 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
#define number of rows and columns for subplots
nrow=3
ncol=2
# make a list of all dataframes 
df_list = [df1 ,df2, df3, df4, df5, df6]
fig, axes = plt.subplots(nrow, ncol)
# plot counter
count=0
for r in range(nrow):
    for c in range(ncol):
        df_list[count].plot(ax=axes[r,c])
        count=+1

Using this code you can plot subplots in any configuration. You need to just define number of rows nrow and number of columns ncol. Also, you need to make list of data frames df_list which you wanted to plot.

The msysgit FAQ on Git cannot create a filedirectory with a long path doesn't seem up to date, as it still links to old msysgit ticket #110. However, according to later ticket #122 the problem has been fixed in msysgit 1.9, thus:

1. Update to msysgit 1.9 (or later)
2. Launch Git Bash
3. Go to your Git repository which 'suffers' of long paths issue
4. Enable long paths support with git config core.longpaths true

So far, it's worked for me very well.

Be aware of important notice in comment on the ticket #122

don't come back here and complain that it breaks Windows Explorer, cmd.exe, bash or whatever tools you're using.

In the interactive console, it's easy to do:

data_all2.columns.tolist()

Or this within a script:

print(data_all2.columns.tolist())

using (var cmd = new SqlCommand("SELECT EmpName FROM [Employee] WHERE EmpID = @id", con))

put [] around table name ;)

There is a more straightforward way to disable scrolling (technically it is more rather interception of a scrolling event and ending it when a condition is met), using just standard functionality. RecyclerView has the method called addOnScrollListener(OnScrollListener listener), and using just this you can stop it from scrolling, just so:

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
        super.onScrollStateChanged(recyclerView, newState);
        if (viewModel.isItemSelected) {
            recyclerView.stopScroll();
        }
    }
});

Use case: Let's say that you want to disable scrolling when you click on one of the items within RecyclerView so you could perform some actions with it, without being distracted by accidentally scrolling to another item, and when you are done with it, just click on the item again to enable scrolling. For that, you would want to attach OnClickListener to every item within RecyclerView, so when you click on an item, it would toggle isItemSelected from false to true. This way when you try to scroll, RecyclerView will automatically call method onScrollStateChanged and since isItemSelected set to true, it will stop immediately, before RecyclerView got the chance, well... to scroll.

Note: for better usability, try to use GestureListener instead of OnClickListener to prevent accidental clicks.

This website has a concise tutorial on how to use SQL Server Management Studio. As you will see you can open a "Query Window", paste your script and run it. It does not allow you to execute scripts by using the file path. However, you can do this easily by using the command line (cmd.exe):

sqlcmd -S .\SQLExpress -i SqlScript.sql

Where SqlScript.sql is the script file name located at the current directory. See this Microsoft page for more examples

I solved this problem by changing the maven setting.xml and repository

Swift 2.2 || Xcode 7.3

I got Amazing results!! with AlamofireImage swift library

It provides multiple features like:

• Asynchronously download
• Auto Purging Image Cache if memory warnings happen for the app
• Image URL caching
• Image Caching
• Avoid Duplicate Downloads

and very easy to implement for your app

Step.1 Install pods

Alamofire 3.3.x

pod 'Alamofire'

AlamofireImage 2.4.x

pod 'AlamofireImage'

Step.2 import and Use

import Alamofire
import AlamofireImage

let downloadURL = NSURL(string: "http://cdn.sstatic.net/Sites/stackoverflow/company/Img/photos/big/6.jpg?v=f4b7c5fee820")!
imageView.af_setImageWithURL(downloadURL)

that's it!! it will take care everything

Great thanks to Alamofire guys, for making iDevelopers life easy ;)

If you want to send your data inside the body, then you have to make a POST or PUT instead of GET.

For me, it looks like you're trying to send the query with uri parameters, which is not related to GET, you can also put these parameters on POST, PUT and so on.

The query is an optional part, separated by a question mark ("?"), that contains additional identification information that is not hierarchical in nature. The query string syntax is not generically defined, but it is commonly organized as a sequence of = pairs, with the pairs separated by a semicolon or an ampersand.

For example:

curl http://server:5050/a/c/getName?param0=foo&param1=bar

show user

to get connected user

 select instance_name from v$instance

to get instance or set in sqlplus

set sqlprompt "_USER'@'_CONNECT_IDENTIFIER> "

All of the current answers are wrong in some cases as they do not consider that timezones change their offset relative to UTC. So in some cases adding 24h is different from adding a calendar day.

Proposed solution

The following solution works for Samoa and keeps the local time constant.

    """
    Add a day to the current day.

    This takes care of historic offset changes and DST.

    Parameters
    ----------
    today : timezone-aware datetime object

    Returns
    -------
    tomorrow : timezone-aware datetime object
    """
    today_utc = today.astimezone(datetime.timezone.utc)
    tz = today.tzinfo
    tomorrow_utc = today_utc + datetime.timedelta(days=1)
    tomorrow_utc_tz = tomorrow_utc.astimezone(tz)
    tomorrow_utc_tz = tomorrow_utc_tz.replace(hour=today.hour,

Adding current working solution for 'FLAG_FULLSCREEN' is deprecated

Add the following to your theme in themes.xml

<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>

Worked perfectly for me.

The public keyword is used only when declaring a class method.

Since you're declaring a simple function and not a class you need to remove public from your code.

One option is to use lapply and class. For example:

> foo <- data.frame(c("a", "b"), c(1, 2))
> names(foo) <- c("SomeFactor", "SomeNumeric")
> lapply(foo, class)
$SomeFactor
[1] "factor"

$SomeNumeric
[1] "numeric"

Another option is str:

> str(foo)
'data.frame':   2 obs. of  2 variables:
 $ SomeFactor : Factor w/ 2 levels "a","b": 1 2
 $ SomeNumeric: num  1 2

Since at the time of installing of any module it mainly put corresponding .pm files in respective directories. So if you want to remove module only for some testing purpose or temporarily best is to find the path where module is stored using perldoc -l <MODULE> and then simply move the module from there to some other location. This approach can also be tried as a more permanent solution but i am not aware of any negative consequences as i do it mainly for testing.

You can use the :checkbox and :checked pseudo-selectors and the .class selector, with that you will make sure that you are getting the right elements, only checked checkboxes with the class you specify.

Then you can easily use the Traversing/map method to get an array of values:

var values = $('input:checkbox:checked.group1').map(function () {
  return this.value;
}).get(); // ["18", "55", "10"]

Just create a single view Model with all the needed information in it, normaly what I do is create a model for every view so I can be specific on every view, either that or make a parent model and inherit it. OR make a model which includes both the views.

Personally I would just add them into one model but thats the way I do it:

public class xViewModel
{
    public int PersonID { get; set; }
    public string PersonName { get; set; }
    public int OrderID { get; set; }
    public int TotalSum { get; set; }
}

@model project.Models.Home.xViewModel

@using(Html.BeginForm())
{
    @Html.EditorFor(x => x.PersonID)
    @Html.EditorFor(x => x.PersonName)
    @Html.EditorFor(x => x.OrderID)
    @Html.EditorFor(x => x.TotalSum)
}

If you want to print multiple rows, you can iterate through the result by using a cursor. e.g. print all names from sys.database_principals

DECLARE @name nvarchar(128)

DECLARE cur CURSOR FOR
SELECT name FROM sys.database_principals

OPEN cur

FETCH NEXT FROM cur INTO @name;
WHILE @@FETCH_STATUS = 0
BEGIN   
PRINT @name
FETCH NEXT FROM cur INTO @name;
END

CLOSE cur;
DEALLOCATE cur;

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

To Add a Function To a new Button on your Form: (and avoid using macro to call function)

After you created your Function (Function MyFunctionName()) and you are in form design view:

1. Add a new button (I don't think you can reassign an old button - not sure though).

2. When the button Wizard window opens up click Cancel.

3. Go to the Button properties Event Tab - On Click - field.

4. At that fields drop down menu select: Event Procedure.

5. Now click on button beside drop down menu that has ... in it and you will be taken to a new Private Sub in the forms Visual Basic window.

6. In that Private Sub type: Call MyFunctionName
   It should look something like this:

   Private Sub Command23_Click()
   
       Call MyFunctionName
   
   End Sub
   

7. Then just save it.

I had this same problem and it turns out I had a '\' instead of a '/' in the xml tag. It still gave the same error but just due to a syntax problem.

To restore a single database:

1. Backup the 'users' database
$ mongodump --db users

2. Restore the 'users' database to a new database called 'users2'
$ mongorestore --db users2 dump/users

To restore all databases:

1. Backup all databases
$ mongodump

2. Restore all databases
$ mongorestore dump

Please rather try:

$JAVA_HOME/bin/java -version

Maven uses $JAVA_HOME for classpath resolution of JRE libs. To be sure to use a certain JDK, set it explicitly before compiling, for example:

export JAVA_HOME=/usr/java/jdk1.7.0_51

Isn't there a version < 1.7 and you're using Maven 3.3.1? In this case the reason is a new prerequisite: https://issues.apache.org/jira/browse/MNG-5780

you can use:

intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

The first problem is that your query string is wrong:

I think this: "INSERT INTO employee(hans,germany) values(?,?)" should be like this: "INSERT INTO employee(name,country) values(?,?)"

The other problem is that you have a parameterized PreparedStatement and you don't set the parameters before running it.

You should add these to your code:

String inserting = "INSERT INTO employee(name,country) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1,"hans"); // <----- this
ps.setString(2,"germany");// <---- and this
ps.executeUpdate();

Brief summary of Microsoft gadget development:

What are they written in? Windows Vista/Seven gadgets are developed in a mix of XML, HTML, CSS, and some IE scripting language. It is also possible to use C# with the latest release of Script#.

How are they packaged/deployed? The actual gadgets are stored in *.gadget files, which are simply the text source files listed above compressed into a single zip file.

Useful references for gadget development:

where do I start? Good introductory references to Windows Vista/Seven gadget development:

• Developing Gadgets for the Windows Sidebar
• Vista Gadgets Introductory tutorial from I-Programmer
• Authoring Sidebar Gadgets in C#
• Developing a Gadget for Windows Sidebar Part 1: The Basics Official MSDN tutorial.

If you are willing to use offline resources, this book appears to be an excellent resource:

• Creating Vista Gadgets: Using HTML, CSS and JavaScript with Examples in RSS, Ajax, ActiveX (COM) and Silverlight
• blog related to book: http://www.innovatewithgadgets.com/

What do I need to know? Some other useful references; not necessarily instructional

• Windows Sidebar (Official MSDN documentation)
• related Stack Overflow question: C# tutorial to write gadgets

Update: Well, this has proven to be a popular answer~ Sharing my own recent experience with Windows 7 gadget development:

Perhaps the easiest way to get started with Windows 7 gadget development is to modify a gadget that has already been developed. I recently did this myself because I wanted a larger clock gadget. Unable to find any, I tinkered with a copy of the standard Windows clock gadget until it was twice as large. I recommend starting with the clock gadget because it is fairly small and well-written. Here is the process I used:

1. Locate the gadget you wish to modify. They are located in several different places. Search for folders named *.gadget. Example: C:\Program Files\Windows Sidebar\Gadgets\Clock.Gadget\
2. Make a copy of this folder (installed gadgets are not wrapped in zip files.)
3. Rename some key parts:
   1. The folder name
   2. The name inside the gadget.xml file. It looks like:<name>Clock</name> This is the name that will be displayed in the "Gadgets Gallery" window.
4. Zip up the entire *.gadget directory.
5. Change the file extension from "zip" to "gadget" (Probably just need to remove the ".zip" extension.)
6. Install your new copy of the gadget by double clicking the new *.gadget file. You can now add your gadget like any other gadget (right click desktop->Gadgets)
7. Locate where this gadget is installed (probably to %LOCALAPPDATA%\Microsoft\Windows Sidebar\)
8. Modify the files in this directory. The gadget is very similar to a web page: HTML, CSS, JS, and image files. The gadget.xml file specifies which file is opened as the "index" page for the gadget.
9. After you save the changes, view the results by installing a new instance of the gadget. You can also debug the JavaScript (The rest of that article is pretty informative, too).

I know you are long past getting a solution. So, this is for others that come along to see how other people are solving the same common problem-- like me.

The examples in the question and answers indicates the use of jQuery and I am using the .change listener/handler/whatever to see if my textarea changes. This should take care of manual text changes, automated text changes, etc. to trigger the

//pseudocode
$(document).ready(function () {
    $('#textarea').change(function () {
        if ($.trim($('#textarea').val()).length < 1) {

            $('#output').html('Someway your box is being reported as empty... sadness.');

        } else {

            $('#output').html('Your users managed to put something in the box!');
            //No guarantee it isn't mindless gibberish, sorry.

        }
    });
});

Seems to work on all the browsers I use. http://jsfiddle.net/Q3LW6/. Message shows when textarea loses focus.

Newer, more thorough example: https://jsfiddle.net/BradChesney79/tjj6338a/

Uses and reports .change(), .blur(), .keydown(), .keyup(), .mousedown(), .mouseup(), .click(), mouseleave(), and .setInterval().

You have two issues in your code.. First you need reference to capture the element on click. Try adding another parameter to your function to reference this. Also active class is for li element initially while you are tryin to add it to "a" element in the function. try this..

<div class="row" style="padding-left:21px;">
 <ul class="nav nav-tabs" style="padding-left:40px;">
      <li class="active filter"><a href="#month" onclick="Data('month',this)">This Month</a></li>
      <li class="filter"><a href="#year" onclick="Data('year',this)">Year</a></li>
      <li class="filter"><a href="#last60"  onclick="Data('last60',this)">60 Days</a></li>
      <li class="filter"><a href="#last90"  onclick="Data('last90',this)">90 Days</a></li>
    </ul> 

</div>

<script>
  function Data(string,element)
    { 
      //1. get some data from server according to month year etc.,
      //2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
      $('.filter').removeClass('active');

      $(element).parent().addClass('active') ;

    } 
</script>

Most easy way: sort files with sort(1) and then use diff(1).

Forgot to take out a non-alloc'd pointer from dealloc. I was getting the exc_bad_access on my rootView of a UINavigationController, but only sometimes. I assumed the problem was in the rootView because it was crashing halfway through its viewDidAppear{}. It turned out to only happen after I popped the view with the bad dealloc{} release, and that was it!

"EXC_BAD_ACCESS" [Switching to process 330] No memory available to program now: unsafe to call malloc

I thought it was a problem where I was trying to alloc... not where I was trying to release a non-alloc, D'oh!

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

Right. Better to use a function:

CREATE OR REPLACE FUNCTION yyyymm() RETURNS text
    LANGUAGE 'plpgsql' AS $$
DECLARE
    retval text;
    m integer;
BEGIN
    retval := EXTRACT(year from current_timestamp);
    m := EXTRACT(month from current_timestamp);
    IF m < 10 THEN retval := retval || '0'; END IF;
    RETURN retval || m;
END $$;

SELECT yyyymm();

DROP TABLE foo;
CREATE TABLE foo (
    key             int PRIMARY KEY,
    colname text DEFAULT yyyymm()
    );
INSERT INTO foo (key) VALUES (0);
SELECT * FROM FOO;

This gives me

 key | colname 
-----+---------
   0 | 200905

Make sure you run createlang plpgsql from the Unix command line, if necessary.

Not sure if this is correct in any sense but this seems to work for me.

someHeader.h
inline int someVar;

I don't have linking/multiple definition issues and it "just works"... ;- )

It's quite handy for "quick" tests... Try to avoid global vars tho, because every says so... ;- )

A numpy-only solution for any number of classes that doesn't require looping:

import numpy as np

classes = 3
true = np.random.randint(0, classes, 50)
pred = np.random.randint(0, classes, 50)

np.bincount(true * classes + pred).reshape((classes, classes))

(Posted on behalf of the OP).

I believe I figured it out.

In my case, I added [class*="col-"] {padding: 0 7.5px;};.

Then added .row {margin: 0 -7.5px;}.

This works pretty well, except there is 1px margin on both sides. So I just make .row {margin: 0 -7.5px;} to .row {margin: 0 -8.5px;}, then it works perfectly.

I have no idea why there is a 1px margin. Maybe someone can explain it?

See the sample I created:

Demo
Code

I don't believe that the framework itself has this class. Maybe a third-party library...

But why not create a Period value-object class to handle this complexity? That way you can ensure other constraints, like validating start vs end datetimes. Something like:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Whatever.Domain.Timing {
    public class Period {
        public DateTime StartDateTime {get; private set;}
        public DateTime EndDateTime {get; private set;}

        public Period(DateTime StartDateTime, DateTime EndDateTime) {
            if (StartDateTime > EndDateTime)
                throw new InvalidPeriodException("End DateTime Must Be Greater Than Start DateTime!");
            this.StartDateTime = StartDateTime;
            this.EndDateTime = EndDateTime;
        }


        public bool Overlaps(Period anotherPeriod){
            return (this.StartDateTime < anotherPeriod.EndDateTime && anotherPeriod.StartDateTime < this.EndDateTime)
        }

        public TimeSpan GetDuration(){
            return EndDateTime - StartDateTime;
        }

    }

    public class InvalidPeriodException : Exception {
        public InvalidPeriodException(string Message) : base(Message) { }    
    }
}

That way you will be able to individually compare each period...

Per documentation, android:weightSum defines the maximum weight sum, and is calculated as the sum of the layout_weight of all the children if not specified explicitly.

Let's consider an example with a LinearLayout with horizontal orientation and 3 ImageViews inside it. Now we want these ImageViews always to take equal space. To acheive this, you can set the layout_weight of each ImageView to 1 and the weightSum will be calculated to be equal to 3 as shown in the comment.

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    <!-- android:weightSum="3" -->
    android:orientation="horizontal"
    android:layout_gravity="center">

   <ImageView
       android:layout_height="wrap_content"       
       android:layout_weight="1"
       android:layout_width="0dp"/>
  .....

weightSum is useful for having the layout rendered correctly for any device, which will not happen if you set width and height directly.

Here's how to change the dosbox.conf file in Linux to increase the size of the window. I actually DID what follows, so I can say it works (in 32-bit PCLinuxOS fullmontyKDE, anyway). The question's answer is in the .conf file itself.

You find this file in Linux at /home/(username)/.dosbox . In Konqueror or Dolphin, you must first check 'Hidden files' or you won't see the folder. Open it with KWrite superuser or your fav editor.

1. Save the file with another name like 'dosbox-0.74original.conf' to preserve the original file in case you need to restore it.
2. Search on 'resolution' and carefully read what the conf file says about changing it. There are essentially two variables: resolution and output. You want to leave fullresolution alone for now. Your question was about WINDOW, not full. So look for windowresolution, see what the comments in conf file say you can do. The best suggestion is to use a bigger-window resolution like 900x800 (which is what I used on a 1366x768 screen), but NOT the actual resolution of your machine (which would make the window fullscreen, and you said you didn't want that). Be specific, replacing the 'windowresolution=original' with 'windowresolution=900x800' or other dimensions. On my screen, that doubled the window size just as it does with the max Font tab in Windows Properties (for the exe file; as you'll see below the ==== marks, 32-bit Windows doesn't need Dosbox).

Then, search on 'output', and as the instruction in the conf file warns, if and only if you have 'hardware scaling', change the default 'output=surface' to something else; he then lists the optional other settings. I changed it to 'output=overlay'. There's one other setting to test: aspect. Search the file for 'aspect', and change the 'false' to 'true' if you want an even bigger window. When I did this, the window took up over half of the screen. With 'false' left alone, I had a somewhat smaller window (I use widescreen monitors, whether laptop or desktop, maybe that's why).

So after you've made the changes, save the file with the original name of dosbox-0.74.conf . Then, type dosbox at the command line or create a Launcher (in KDE, this is a right click on the desktop) with the command dosbox. You still have to go through the mount command (i.e., mount c~ c:\123 if that's the location and file you'll execute). I'm sure there's a way to make a script, but haven't yet learned how to do that.

Both your examples are equivalent. However, the first one is less obvious and more "hacky", while the second one clearly states your intention.

int (*pointer)[280];
pointer = tab1;

pointer points to an 1D array of 280 integers. In your assignment, you actually assign the first row of tab1. This works since you can implicitly cast arrays to pointers (to the first element).

When you are using pointer[5][12], C treats pointer as an array of arrays (pointer[5] is of type int[280]), so there is another implicit cast here (at least semantically).

In your second example, you explicitly create a pointer to a 2D array:

int (*pointer)[100][280];
pointer = &tab1;

The semantics are clearer here: *pointer is a 2D array, so you need to access it using (*pointer)[i][j].

Both solutions use the same amount of memory (1 pointer) and will most likely run equally fast. Under the hood, both pointers will even point to the same memory location (the first element of the tab1 array), and it is possible that your compiler will even generate the same code.

The first solution is "more advanced" since one needs quite a deep understanding on how arrays and pointers work in C to understand what is going on. The second one is more explicit.

I think this should do the trick:

<table border="1px" align="center">

According to http://w3schools.com/tags/tag_table.asp this is deprecated, but try it. If it does not work, go for styles, as mentioned on the site.

It is as easy as specifying a padding bottom the same size as the width in percent. So if you have a width of 50%, just use this example below

id or class{
    width: 50%;
    padding-bottom: 50%;
}

Here is a jsfiddle http://jsfiddle.net/kJL3u/2/

Edited version with responsive text: http://jsfiddle.net/kJL3u/394

Set-ExecutionPolicy Unrestricted -Scope CurrentUser

This will set the execution policy for the current user (stored in HKEY_CURRENT_USER) rather than the local machine (HKEY_LOCAL_MACHINE). This is useful if you don't have administrative control over the computer.

An other example would be on the "created_on" column where you want to let the database handle the date creation

Add-Content is default ASCII and add new line however Add-Content brings locked files issues too.

html, body {
    height: 100%;
    width: 100%;
}

html {
    display: table;
    margin: auto;
}

body {
    padding-top: 50px;
    display: table-cell;
}

div {
    margin: auto;
}

This will center align objects and then also center align the items within them to center align multiple objects with different widths.

We just ran into this ourselves when running dotnet ef database update using ASP.Net Core 2.1; looks like relative paths aren't supported with AttachDbFileName.

System.Data.SqlClient.SqlException (0x80131904): Cannot attach the file '.\OurDbName.mdf' as database 'OurDbName'.

Just wanted to express that here for other people who might be bumping into this. The "fix" is use absolute paths.

Incorrect:

SELECT * FROM customers WHERE name LIKE '%Bob Smith%';

Instead:

select count(*)
from rearp.customers c
where c.name  LIKE '%Bob smith.8%';

select count will just query (totals)

C will link the db.table to the names row you need this to index

LIKE should be obvs

8 will call all references in DB 8 or less (not really needed but i like neatness)

The way I solved this was using flexbox. By using flexbox to layout the contents of your container div, you can have flexbox automatically distribute free space to an item above the one you want to have "stick to the bottom".

For example, say this is your container div with some other block elements inside it, and that the blue box (third one down) is a paragraph and the purple box (last one) is the one you want to have "stick to the bottom".

By setting this layout up with flexbox, you can set flex-grow: 1; on just the paragraph (blue box) and, if it is the only thing with flex-grow: 1;, it will be allocated ALL of the remaining space, pushing the element(s) after it to the bottom of the container like this:

(apologies for the terrible, quick-and-dirty graphics)

Add a div with ID imgDiv and make your script

 document.getElementById('imgDiv').innerHTML='<img src=\'http://webpage.com/images/'+document.getElementById('imagename').value +'.png\'>'

I tried to stay as close to your original as tp not overwhelm you with jQuery and such

Your old ugly style is automatically compiled by JAVAC 1.6 as :

StringBuilder sb = new StringBuilder("What do you get if you multiply ");
sb.append(varSix);
sb.append(" by ");
sb.append(varNine);
sb.append("?");
String s =  sb.toString();

So there is absolutely no difference between this and using a StringBuilder.

String.format is a lot more heavyweight since it creates a new Formatter, parses your input format string, creates a StringBuilder, append everything to it and calls toString().

this is command for composer update please try this...

In case you don't want to pollute your model with annotations and want to perform some custom operations, you could use mixins.

ObjectMapper mapper = new ObjectMapper();
SimpleModule simpleModule = new SimpleModule();
simpleModule.setMixInAnnotation(Person.class, PersonMixin.class);
mapper.registerModule(simpleModule);

Override age:

public abstract class PersonMixin {
    @JsonSerialize(using = PersonAgeSerializer.class)
    public String age;
}

Do whatever you need with the age:

public class PersonAgeSerializer extends JsonSerializer<Integer> {
    @Override
    public void serialize(Integer integer, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
        jsonGenerator.writeString(String.valueOf(integer * 52) + " months");
    }
}

Use numpy.apply_along_axis(). Assuming your matrix is 2D, you can use like:

import numpy as np
mymatrix = np.matrix([[11,12,13],
                      [21,22,23],
                      [31,32,33]])
def myfunction( x ):
    return sum(x)

print np.apply_along_axis( myfunction, axis=1, arr=mymatrix )
#[36 66 96]

I created a bin directory at the project_dir level, then created a release/debug directory inside the bin folder, which solved the problem for me.

If you want to delete any commit then you might need to use git rebase command

git rebase -i HEAD~2

it will show you last 2 commit messages, if you delete the commit message and save that file deleted commit will automatically disappear...

No need array_push function.if you want to add multiple item it works fine. simply try this and it worked for me

class line_details {
   var $commission_one=array();
   foreach($_SESSION['commission'] as $key=>$data){
          $row=  explode('-', $key);
          $this->commission_one[$row['0']]= $row['1'];            
   }

}

I know its an old post but I found a nice solution with PoweShell where you can find SQL instances installed on local or a remote machine including the version and also be extend get other properties.

$MachineName = ‘.’ # Default local computer Replace . with server name for a remote computer

$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey(‘LocalMachine’, $MachineName)
$regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Microsoft SQL Server\\Instance Names\\SQL" )
$values = $regkey.GetValueNames()
$values | ForEach-Object {$value = $_ ; $inst = $regKey.GetValue($value); 
              $path = "SOFTWARE\\Microsoft\\Microsoft SQL Server\\"+$inst+"\\MSSQLServer\\"+"CurrentVersion";
              #write-host $path; 
              $version = $reg.OpenSubKey($path).GetValue("CurrentVersion");
                          write-host "Instance" $value;
              write-host  "Version" $version}

Use padding on the cells and border-spacing on the table. The former will give you cellpadding while the latter will give you cellspacing.

table { border-spacing: 5px; } /* cellspacing */

th, td { padding: 5px; } /* cellpadding */

The answer is no. When the parser reaches the first return statement, it will direct control back to the calling function - your second return statement will never be executed.

There are two possible result rearrangements (following example by @eumiro). Einops package provides a powerful notation to describe such operations non-ambigously

# this version corresponds to eumiro's answer
>> einops.rearrange(a, '(x y) z -> z y x', x=3)

        [ 4, 10, 16]],

       [[ 1,  7, 13],
        [ 3,  9, 15],
        [ 5, 11, 17]]])

# this has the same shape, but order of elements is different (note that each paer was trasnposed)
>> einops.rearrange(a, '(x y) z -> z x y', x=3)

array([[[ 0,  2,  4],
        [ 6,  8, 10],

Path is a new feature of Django 2.0. Explained here : https://docs.djangoproject.com/en/2.0/releases/2.0/#whats-new-2-0

Look like more pythonic way, and enable to not use regular expression in argument you pass to view... you can ue int() function for exemple.

If the HTMLElement is input[type='button'], input[type='submit'], etc.

<input id="ShowButton" type="button" value="Show">
<input id="ShowButton" type="submit" value="Show">

change it using this code:

document.querySelector('#ShowButton').value = 'Hide';

If, the HTMLElement is button[type='button'], button[type='submit'], etc:

<button id="ShowButton" type="button">Show</button>
<button id="ShowButton" type="submit">Show</button>

change it using any of these methods,

document.querySelector('#ShowButton').innerHTML = 'Hide';
document.querySelector('#ShowButton').innerText = 'Hide';
document.querySelector('#ShowButton').textContent = 'Hide';

Please note that

• input is an empty tag and cannot have innerHTML, innerText or textContent
• button is a container tag and can have innerHTML, innerText or textContent

Ignore this answer if you ain't using asp.net-web-forms, asp.net-ajax and rad-grid

You must use value instead of innerHTML.

Try this.

document.getElementById("ShowButton").value= "Hide Filter";

And since you are running the button at server the ID may get mangled in the framework. I so, try

document.getElementById('<%=ShowButton.ClientID %>').value= "Hide Filter";

Another better way to do this is like this.

On markup, change your onclick attribute like this. onclick="showFilterItem(this)"

Now use it like this

function showFilterItem(objButton) {
    if (filterstatus == 0) {
        filterstatus = 1;
        $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
        objButton.value = "Hide Filter";
    }
    else {
        filterstatus = 0;
        $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
        objButton.value = "Show filter";
    }
}

map creates a new list by applying a function to every element of the source:

xs = [1, 2, 3]

# all of those are equivalent — the output is [2, 4, 6]
# 1. map
ys = map(lambda x: x * 2, xs)
# 2. list comprehension
ys = [x * 2 for x in xs]
# 3. explicit loop
ys = []
for x in xs:
    ys.append(x * 2)

n-ary map is equivalent to zipping input iterables together and then applying the transformation function on every element of that intermediate zipped list. It's not a Cartesian product:

xs = [1, 2, 3]
ys = [2, 4, 6]

def f(x, y):
    return (x * 2, y // 2)

# output: [(2, 1), (4, 2), (6, 3)]
# 1. map
zs = map(f, xs, ys)
# 2. list comp
zs = [f(x, y) for x, y in zip(xs, ys)]
# 3. explicit loop
zs = []
for x, y in zip(xs, ys):
    zs.append(f(x, y))

I've used zip here, but map behaviour actually differs slightly when iterables aren't the same size — as noted in its documentation, it extends iterables to contain None.

Listen to @milkplusvellocet, I'd recommend you to implement the Comparable interface to your class as well.

Just contributing to the answers of others:

String.compareTo() will tell you how different a string is from another.

e.g. System.out.println( "Test".compareTo("Tesu") ); will print -1 and System.out.println( "Test".compareTo("Tesa") ); will print 19

and nerdy and geeky one-line solution to this task would be:

return this.lastName.equals(s.getLastName()) ? this.lastName.compareTo(s.getLastName()) : this.firstName.compareTo(s.getFirstName());

Explanation:

this.lastName.equals(s.getLastName()) checks whether lastnames are the same or not this.lastName.compareTo(s.getLastName()) if yes, then returns comparison of last name. this.firstName.compareTo(s.getFirstName()) if not, returns the comparison of first name.

I spent about one day to configure the new gmaps API (Google Maps Android API v2) on the Android emulator. None of the methods of those I found on the Internet was working correctly for me. But still I did it. Here is how:

1. Create a new emulator with the following configuration:

On the other versions I could not configure because of various errors when I installed the necessary applications.

2) Start the emulator and install the following applications:

• GoogleLoginService.apk
• GoogleServicesFramework.apk
• Phonesky.apk

You can do this with following commands:

2.1) adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock0 /system
2.2) adb shell chmod 777 /system/app
2.3-2.5) adb push Each_of_the_3_apk_files.apk /system/app/

Links to download APK files. I have copied them from my rooted Android device.

• GoogleLoginService.apk
• GoogleServicesFramework.apk
• Phonesky.apk

3) Install Google Play Services and Google Maps on the emulator. I have an error 491, if I install them from Google Play store. I uploaded the apps to the emulator and run the installation locally. (You can use adb to install this). Links to the apps:

• Google Maps
• Google Play services

4) I successfully run a demo sample on the emulator after these steps. Here is a screenshot:

After some experimentation I came up with this implementation:

$('.detect-change')
    .on('change cut paste', function(e) {
        console.log("Change detected.");
        contentModified = true;
    })
    .keypress(function(e) {
        if (e.which !== 0 && e.altKey == false && e.ctrlKey == false && e.metaKey == false) {
            console.log("Change detected.");
            contentModified = true;
        }
    });

Handles changes to any kind of input and select as well as textareas ignoring arrow keys and things like ctrl, cmd, function keys, etc.

Note: I've only tried this in FF since it's for a FF add-on.

A way to do this without Linq & Lambdas

string source = "a,b, b, c";
string[] items = source.Split(new char[] { ',', ' ' }, StringSplitOptions.RemoveEmptyEntries);

From the Python for android site:

Python for android is a project to create your own Python distribution including the modules you want, and create an apk including python, libs, and your application.

Notice that sapply with "[" can be used to extract either the first or second items in those lists so:

before$type_1 <- sapply(strsplit(as.character(before$type),'_and_'), "[", 1)
before$type_2 <- sapply(strsplit(as.character(before$type),'_and_'), "[", 2)
before$type <- NULL

And here's a gsub method:

before$type_1 <- gsub("_and_.+$", "", before$type)
before$type_2 <- gsub("^.+_and_", "", before$type)
before$type <- NULL

In my circumstances the error was due to the fact the listener did not have the db's service registered. I solved this by registering the services. Example:

My descriptor in tnsnames.ora:

LOCALDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = LOCALDB)
    )
  )

So, I proceed to register the service in the listener.ora manually:

SID_LIST_LISTENER =
    (SID_DESC =
      (GLOBAL_DBNAME = LOCALDB)
      (ORACLE_HOME = C:\Oracle\product\11.2.0\dbhome_1)
      (SID_NAME = LOCALDB)
    )

Finally, restart the listener by command:

> lsnrctl stop
> lsnrctl start

Done!

JOIN

When using JOIN against an entity associations, JPA will generate a JOIN between the parent entity and the child entity tables in the generated SQL statement.

So, taking your example, when executing this JPQL query:

FROM Employee emp
JOIN emp.department dep

Hibernate is going to generate the following SQL statement:

SELECT emp.*
FROM employee emp
JOIN department dep ON emp.department_id = dep.id

Note that the SQL SELECT clause contains only the employee table columns, and not the department ones. To fetch the department table columns, we need to use JOIN FETCH instead of JOIN.

JOIN FETCH

So, compared to JOIN, the JOIN FETCH allows you to project the joining table columns in the SELECT clause of the generated SQL statement.

So, in your example, when executing this JPQL query:

FROM Employee emp
JOIN FETCH emp.department dep

Hibernate is going to generate the following SQL statement:

SELECT emp.*, dept.*
FROM employee emp
JOIN department dep ON emp.department_id = dep.id

Note that, this time, the department table columns are selected as well, not just the ones associated with the entity listed in the FROM JPQL clause.

Also, JOIN FETCH is a great way to address the LazyInitializationException when using Hibernate as you can initialize entity associations using the FetchType.LAZY fetching strategy along with the main entity you are fetching.

This is an improvement over the accepted answer.

    String passphrase = "My passphrase";
    String encrypted = encrypt(passphrase, plaintext);
    String decrypted = decrypt(passphrase, encrypted);

private static Cipher getCipher() throws NoSuchPaddingException, NoSuchAlgorithmException {
    return Cipher.getInstance("AES/CBC/PKCS5PADDING");
}

public static String encrypt(String passphrase, String value) throws GeneralSecurityException {
    byte[] initVector = new byte[16];
    SecureRandom.getInstanceStrong().nextBytes(initVector);
    Cipher cipher = getCipher();
    cipher.init(Cipher.ENCRYPT_MODE, getKeySpec(passphrase), new IvParameterSpec(initVector));
    byte[] encrypted = cipher.doFinal(value.getBytes());
    return DatatypeConverter.printBase64Binary(initVector) +
            DatatypeConverter.printBase64Binary(encrypted);
}

public static String decrypt(String passphrase, String encrypted) throws GeneralSecurityException {
    byte[] initVector = DatatypeConverter.parseBase64Binary(encrypted.substring(0, 24));
    Cipher cipher = getCipher();
    cipher.init(Cipher.DECRYPT_MODE, getKeySpec(passphrase), new IvParameterSpec(initVector));
    byte[] original = cipher.doFinal(DatatypeConverter.parseBase64Binary(encrypted.substring(24)));
    return new String(original);
}

In your build.gradle file add the following

implementation ("com.facebook.react:react-native:0.51.0") {

Path.GetDirectoryName(filename);

This will return "C:\MyDirectory" in your case

With less you can set it up like this;

.table tbody tr {
    &.error > td { background-color: red !important; }
    &.error:hover > td { background-color: yellow !important; }
    &.success > td { background-color: green !important; }
    &.success:hover > td { background-color: yellow !important; }
    ...
}

That did the trick for me.

To see the full code(query) written in stored procedure/ functions, Use below Command:

sp_helptext procedure/function_name

for function name and procedure name don't add prefix 'dbo.' or 'sys.'.

don't add brackets at the end of procedure or function name and also don't pass the parameters.

use sp_helptext keyword and then just pass the procedure/ function name.

use below command to see full code written for Procedure:

sp_helptext ProcedureName

use below command to see full code written for function:

You cannot test for string[] in the general case but you can test for Array quite easily the same as in JavaScript https://stackoverflow.com/a/767492/390330

If you specifically want for string array you can do something like:

if (Array.isArray(value)) {
   var somethingIsNotString = false;
   value.forEach(function(item){
      if(typeof item !== 'string'){
         somethingIsNotString = true;
      }
   })
   if(!somethingIsNotString && value.length > 0){
      console.log('string[]!');
   }
}

You might also try an elseif.

x <- 1
if (x ==1){
    print('same')
} else if (x > 1){
    print('bigger')
} else {
    print('smaller')
}

Something like this:

unsigned int getConsoleInput(char **pStrBfr) //pass in pointer to char pointer, returns size of buffer
{
    char * strbfr;
    int c;
    unsigned int i;
    i = 0;
    strbfr = (char*)malloc(sizeof(char));
    if(strbfr==NULL) goto error;
    while( (c = getchar()) != '\n' && c != EOF )
    {
        strbfr[i] = (char)c;
        i++;
        strbfr = (void*)realloc((void*)strbfr,sizeof(char)*(i+1));
        //on realloc error, NULL is returned but original buffer is unchanged
        //NOTE: the buffer WILL NOT be NULL terminated since last
        //chracter came from console
        if(strbfr==NULL) goto error;
    }
    strbfr[i] = '\0';
    *pStrBfr = strbfr; //successfully returns pointer to NULL terminated buffer
    return i + 1; 
    error:
    *pStrBfr = strbfr;
    return i + 1;
}

The best way to do, I think, is to handle it like the MSDN said on http://msdn.microsoft.com/en-us/library/system.windows.forms.control.previewkeydown.aspx

But handle it, how you really need it. My way (in the example below) is to catch every KeyDown ;-)

    /// <summary>
    /// onPreviewKeyDown
    /// </summary>
    /// <param name="e"></param>
    protected override void OnPreviewKeyDown(PreviewKeyDownEventArgs e)
    {
        e.IsInputKey = true;
    }

    /// <summary>
    /// onKeyDown
    /// </summary>
    /// <param name="e"></param>
    protected override void OnKeyDown(KeyEventArgs e)
    {
        Input.SetFlag(e.KeyCode);
        e.Handled = true;
    }

    /// <summary>
    /// onKeyUp
    /// </summary>
    /// <param name="e"></param>
    protected override void OnKeyUp(KeyEventArgs e)
    {
        Input.RemoveFlag(e.KeyCode);
        e.Handled = true;
    }

Anyone can use underscore _ (its Okay)

No one should use hypen - (its Bad practice)

No one should use capital letters inside package names (Bad practice)

NOTE: Here "Bad Practice" is meant for technically you are allowed to use that, but conventionally its not in good manners to write.

char array[10];
sprintf(array, "%f", 3.123);

sprintf: (from MSDN)

You can concat the data in this way:

InfoDF = pd.DataFrame()
tempDF = pd.DataFrame(rows,columns=['id','min_date'])

InfoDF = pd.concat([InfoDF,tempDF])

You can't do this with jQuery, visible="false" in asp.net means the control isn't rendered into the page. If you want the control to go to the client, you need to do style="display: none;" so it's actually in the HTML, otherwise there's literally nothing for the client to show, since the element wasn't in the HTML your server sent.

If you remove the visible attribute and add the style attribute you can then use jQuery to show it, like this:

$("#elementID").show();

Old Answer (before patrick's catch)

To change visibility, you need to use .css(), like this:

$("#elem").css('visibility', 'visible');

Unless you need to have the element occupy page space though, use display: none; instead of visibility: hidden; in your CSS, then just do:

$("#elem").show();

The .show() and .hide() functions deal with display instead of visibility, like most of the jQuery functions :)

ideal solution but not supported in IE

tr:not(:first-child) {css}

second solution would be to style all tr's and then override with css for first-child:

tr {css}
tr:first-child {override css above}

Thankfully, with C++11 there is also the more pleasing approach of using raw string literals.

printf("She said \"time flies like an arrow, but fruit flies like a banana\".");

Becomes:

printf(R"(She said "time flies like an arrow, but fruit flies like a banana".)");

With respect to the addition of brackets after the opening quote, and before the closing quote, note that they can be almost any combination of up to 16 characters, helping avoid the situation where the combination is present in the string itself. Specifically:

any member of the basic source character set except: space, the left parenthesis (, the right parenthesis ), the backslash , and the control characters representing horizontal tab, vertical tab, form feed, and newline" (N3936 §2.14.5 [lex.string] grammar) and "at most 16 characters" (§2.14.5/2)

How much clearer it makes this short strings might be debatable, but when used on longer formatted strings like HTML or JSON, it's unquestionably far clearer.

I also faced the similar problem with JSON output format. This code worked for me with the above JSON format.

package com.test.ameba;

import java.util.List;

public class OutputRanges {
    public List<Range> OutputRanges;
    public String Message;
    public String Entity;

    /**

     */
    public List<Range> getOutputRanges() {
        return OutputRanges;
    }

    /**
     * @param outputRanges the outputRanges to set
     */
    public void setOutputRanges(List<Range> outputRanges) {
        OutputRanges = outputRanges;
    }

    /**
     * @return the message
     */
    public String getMessage() {
        return Message;
    }

    /**
     * @param message the message to set
     */
    public void setMessage(String message) {
        Message = message;
    }

    /**
     * @return the entity
     */
    public String getEntity() {
        return Entity;
    }

    /**
     * @param entity the entity to set
     */
    public void setEntity(String entity) {
        Entity = entity;
    }
}

package com.test;


public class Range {
    public String Name;
    /**

    public String getName() {
        return Name;
    }
    /**

    public void setName(String name) {
        Name = name;
    }

    public Object[] Value;
    /**
     * @return the value
     */
    public Object[] getValue() {
        return Value;
    }

You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file.

Instead of

move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);

Use

$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);

Changed to reflect your question, will product a random number based on the current time and append the extension from the originally uploaded file.

It is possible to use the convert function here, but 36 characters are enough to hold the unique identifier value:

convert(nvarchar(36), requestID) as requestID

Spaces are simply replaced by "%20" like :

http://www.example.com/my%20beautiful%20page

Most terse version I can think of

Len(Trim(TextBox1.Value)) = 0

If you need to do this multiple times, wrap it in a function

Public Function HasContent(text_box as Object) as Boolean
    HasContent = (Len(Trim(text_box.Value)) > 0)
End Function

Usage

If HasContent(TextBox1) Then

I have created Delayed component using Hooks and TypeScript

import React, { useState, useEffect } from 'react';

type Props = {
  children: React.ReactNode;
  waitBeforeShow?: number;
};

const Delayed = ({ children, waitBeforeShow = 500 }: Props) => {
  const [isShown, setIsShown] = useState(false);

  useEffect(() => {
    setTimeout(() => {
      setIsShown(true);
    }, waitBeforeShow);
  }, [waitBeforeShow]);

  return isShown ? children : null;
};

export default Delayed;

Just wrap another component into Delayed

export function LoadingScreen = () => {
  return (
    <Delayed>
      <div />
    </Delayed>
  );
};

In the example you gave, the method will never throw an IOException, therefore the declaration is wrong (but valid). My guess is that the original method threw the IOException, but it was then updated to handle the exception within but the declaration was not changed.

If the user name that is in the connection string has access to more then one database you have to specify the database you want the connection string to connect to. If your user has only one database available then you are correct that it doesn't matter. But it is good practice to put this in your connection string.

I have found that if I save my query(spool_script_file.sql) and call it using this

@c:\client\queries\spool_script_file.sql as script(F5)

My output now is just the results with out the commands at the top.

I found this solution on the oracle forums.

This is probably not a direct answer to what you're asking, but when I need to transfer files over a SSH session I use WinSCP, which is an excellent file transfer program over SCP or SFTP. Of course this assumes you're on Windows.

A slight more difficult answer that uses ControlTemplate and has an animation effect (adapted from https://docs.microsoft.com/en-us/dotnet/framework/wpf/controls/customizing-the-appearance-of-an-existing-control)

In your resource dictionary define a control template for your button like this one:

<ControlTemplate TargetType="Button" x:Key="testButtonTemplate2">
    <Border Name="RootElement">
        <Border.Background>
            <SolidColorBrush x:Name="BorderBrush" Color="Black"/>
        </Border.Background>

        <Grid Margin="4" >
            <Grid.Background>
                <SolidColorBrush x:Name="ButtonBackground" Color="Aquamarine"/>
            </Grid.Background>
            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="4,5,4,4"/>
        </Grid>
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="CommonStates">
                <VisualState x:Name="Normal"/>
                <VisualState x:Name="MouseOver">
                    <Storyboard>
                        <ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
                    </Storyboard>
                </VisualState>
                <VisualState x:Name="Pressed">
                    <Storyboard>
                        <ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
                    </Storyboard>
                </VisualState>
            </VisualStateGroup>
        </VisualStateManager.VisualStateGroups>
    </Border>
</ControlTemplate>

in your XAML you can use the template above for your button as below:

Define your button

<Button Template="{StaticResource testButtonTemplate2}" 
HorizontalAlignment="Center" VerticalAlignment="Center" 
Foreground="White">My button</Button>

I think this will be better one.

The nature and even existence of file extensions is platform-dependent (some obscure platforms don't even have them, remember) -- in other systems they're only conventional (UNIX and its ilk), while in still others they have definite semantics and in some cases specific limits on length or character content (Windows, etc.).

Since the maintainers have asked that you use ".yaml", that's as close to an "official" ruling as you can get, but the habit of 8.3 is hard to get out of (and, appallingly, still occasionally relevant in 2013).

Make your variable nullable. Like:

Color? color = null;

or

Nullable<Color> color = null;

As help to anybody that had the same problem as me, I accidentally mistyped the implementation type instead of the interface e.g.

instead of

Well, goto, but that is ugly, and not always possible. You can also place the loops into a method (or an anon-method) and use return to exit back to the main code.

    // goto
    for (int i = 0; i < 100; i++)
    {
        for (int j = 0; j < 100; j++)
        {
            goto Foo; // yeuck!
        }
    }
Foo:
    Console.WriteLine("Hi");

vs:

// anon-method
Action work = delegate
{
    for (int x = 0; x < 100; x++)
    {
        for (int y = 0; y < 100; y++)
        {
            return; // exits anon-method
        }
    }
};
work(); // execute anon-method
Console.WriteLine("Hi");

Note that in C# 7 we should get "local functions", which (syntax tbd etc) means it should work something like:

// local function (declared **inside** another method)
void Work()
{
    for (int x = 0; x < 100; x++)
    {
        for (int y = 0; y < 100; y++)
        {
            return; // exits local function
        }
    }
};
Work(); // execute local function
Console.WriteLine("Hi");

Use String.substring(beginIndex, endIndex)

str.substring(0, str.length() - 2);

The substring begins at the specified beginIndex and extends to the character at index (endIndex - 1)

Prerequisites to execute this command -

1. pip (recursive acronym of Pip Installs Packages) is a package management system used to install and manage software packages written in Python. Many packages can be found in the Python Package Index (PyPI).

   sudo apt-get install python-pip

2. Install Virtual Environment. Used to create virtual environment, to install packages and dependencies of multiple projects isolated from each other.

   sudo pip install virtualenv

3. Install virtual environment wrapper About virtual env wrapper

   sudo pip install virtualenvwrapper

After Installing prerequisites you need to bring virtual environment wrapper into action to create virtual environment. Following are the steps -

1. set virtual environment directory in path variable- export WORKON_HOME=(directory you need to save envs)

2. source /usr/local/bin/virtualenvwrapper.sh -p $WORKON_HOME

As mentioned by @Mike, source `which virtualenvwrapper.sh` or which virtualenvwrapper.sh can used to locate virtualenvwrapper.sh file.

It's best to put above two lines in ~/.bashrc to avoid executing the above commands every time you open new shell. That's all you need to create environment using mkvirtualenv

Points to keep in mind -

• Under Ubuntu, you may need install virtualenv and virtualenvwrapper as root. Simply prefix the command above with sudo.
• Depending on the process used to install virtualenv, the path to virtualenvwrapper.sh may vary. Find the appropriate path by running $ find /usr -name virtualenvwrapper.sh. Adjust the line in your .bash_profile or .bashrc script accordingly.

For modern docker engines use this command :

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

and for older engines use :

docker inspect --format '{{ .NetworkSettings.IPAddress }}' container_name_or_id

For your problem, an Exists filter would probably perform the fastest.

open your /etc/paths file, put /usr/local/bin on top of /usr/bin

$ sudo vi /etc/paths
/usr/local/bin
/usr/local/sbin
/usr/bin
/bin
/usr/sbin
/sbin

and Restart the terminal, @mmel

How easy :)

date("F j, Y", strtotime( '-1 days' ) );

Example:

echo date("Y-m-j H:i:s", strtotime( '-1 days' ) ); // 2018-07-18 07:02:43

Output:

Sql Data Reader  100 times table load speed 1000 rows: 2031 milliseconds
100 rows:
Sql Data Adapter 100 times table fill speed 100 rows: 125 milliseconds

10 rows:
Sql Data Adapter 100 times table fill speed 10 rows: 32 milliseconds
Sql Data Reader  100 times table load speed 10 rows: 93 milliseconds

For performance issues, using the SqlDataAdapter.Fill method is far more efficient. So unless you want to shoot yourself in the foot use that. It works faster for small and large data sets.

int(limit) returns the value converted into an integer, and doesn't change it in place as you call the function (which is what you are expecting it to).

Do this instead:

limit = int(limit)

if 'limit' in user_data :
    limit = int(user_data['limit'])

You could add [asc] or [desc] at the end of the order by to get the earliest or latest records

For example, this will give you the latest records first

ORDER BY stamp DESC

Append the LIMIT clause after ORDER BY

You can use some functional programming approach, transforming data:

['12','34','35','231'].map{|i| "'#{i}'"}.join(",")

Dude I know totally how you feel, but don't forget about inline styling. It is almost the super saiyan of the CSS specificity

So it should look something like this for you,

<span class="icon-bar" style="background-color: black !important;">
</span>
<span class="icon-bar" style="background-color: black !important;">
</span>
<span class="icon-bar" style="background-color: black !important;">
</span>

Using a pure javascript, you can handle the reference to the object that dispatched the event.

function (event) {
    console.log(event.target.value);
}

You are missimg @ModelAttribute annotation for UserProfessionalForm professionalForm parameter in forgotPassword method.

@RequestMapping(value = "proffessional", method = RequestMethod.POST)
public @ResponseBody
String forgotPassword(@ModelAttribute UserProfessionalForm professionalForm,
        BindingResult result, Model model) {

    UserProfileVO userProfileVO = new UserProfileVO();
    userProfileVO.setUser(sessionData.getUser());
    userService.saveUserProfile(userProfileVO);
    model.addAttribute("professional", professionalForm);
    return "Your Professional Details Updated";
}

Try this,

x in mylist is better and more readable than x in mylist[:] and your len(x) should be equal to 3.

>>> mylist = [[1,2,3],[4,5,6,7],[8,9,10]]
>>> for x in mylist:
...      if len(x)==3:
...        print x
...
[1, 2, 3]
[8, 9, 10]

or if you need more pythonic use list-comprehensions

>>> [x for x in mylist if len(x)==3]
[[1, 2, 3], [8, 9, 10]]
>>>

you should use this code:

$json = json_encode(array_map('utf8_encode', $arr))

array_map function converts special characters in UTF8 standard

JAR stands for Java ARchive. It's a file format based on the popular ZIP file format and is used for aggregating many files into one. Although JAR can be used as a general archiving tool, the primary motivation for its development was so that Java applets and their requisite components (.class files, images and sounds) can be downloaded to a browser in a single HTTP transaction, rather than opening a new connection for each piece. This greatly improves the speed with which an applet can be loaded onto a web page and begin functioning. The JAR format also supports compression, which reduces the size of the file and improves download time still further. Additionally, individual entries in a JAR file may be digitally signed by the applet author to authenticate their origin.

Use count(d.ertek) or count(d.id) instead of count(d). This can be happen when you have composite primary key at your entity.

If you closed the project, you can open it again easily by going to the top bar (alt) > ?Project > Open Project Top menu > Project > Open Project You will get a menu where you can open closed projects that can be preventing you from opening these projects through the File menu. The window that lets you open any closed projects after you go through the menu listed previously

The code snippet in the linked proposed duplicate reads user input.

ECHO A current build of Test Harness exists.
set /p delBuild=Delete preexisting build [y/n]?: 

The user can type as many letters as they want, and it will go into the delBuild variable.

Yes you could use an <input type="hidden" /> and set the value of that hidden field in your javascript code so it gets posted with your other form data.

Sven Marnach excellent solution is directly translatable into ElementTree which is part of recent Python distributions:

from xml.etree import ElementTree as ET

s = """<table>
  <tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
  <tr><td>a</td><td>b</td><td>c</td></tr>
  <tr><td>d</td><td>e</td><td>f</td></tr>
  <tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""

table = ET.XML(s)
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
    values = [col.text for col in row]
    print(dict(zip(headers, values)))

same output as Sven Marnach's answer...

A typographical error in the string describing the database driver can also produce the error.

A string specified as:

"jdbc:mysql//localhost:3307/dbname,"usrname","password"

can result in a "no suitable driver found" error. The colon following "mysql" is missing in this example.

The correct driver string would be:

jdbc:mysql://localhost:3307/dbname,"usrname","password"

This link has solution of how to get it working. Removing "pom.xml" from the "Profiles:" line and then click "Run".

The key difference: NSMutableDictionary can be modified in place, NSDictionary cannot. This is true for all the other NSMutable* classes in Cocoa. NSMutableDictionary is a subclass of NSDictionary, so everything you can do with NSDictionary you can do with both. However, NSMutableDictionary also adds complementary methods to modify things in place, such as the method setObject:forKey:.

You can convert between the two like this:

NSMutableDictionary *mutable = [[dict mutableCopy] autorelease];
NSDictionary *dict = [[mutable copy] autorelease]; 

Presumably you want to store data by writing it to a file. NSDictionary has a method to do this (which also works with NSMutableDictionary):

BOOL success = [dict writeToFile:@"/file/path" atomically:YES];

To read a dictionary from a file, there's a corresponding method:

NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:@"/file/path"];

If you want to read the file as an NSMutableDictionary, simply use:

NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:@"/file/path"];

Use this function. It works like a charm. replace "|" with the char to explode/split and the values 1,2,3,etc are based on the number of entries in the data-set: Value_ONE|Value_TWO|Value_THREE.

SUBSTRING_INDEX(SUBSTRING_INDEX(`tblNAME`.`tblFIELD`, '|', 1), '|', -1) AS PSI,
SUBSTRING_INDEX(SUBSTRING_INDEX(`tblNAME`.`tblFIELD`, '|', 2), '|', -1) AS GPM,
SUBSTRING_INDEX(SUBSTRING_INDEX(`tblNAME`.`tblFIELD`, '|', 3), '|', -1) AS LIQUID

I hope this helps.

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

And this gives the total:

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0

If you need more detail, run:

sp_who2 'Active'

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)

This can be done without specifying the columns in the INSERT INTO part if you are supplying values for all columns in the SELECT part.

Let's say table1 has two columns. This query should work:

INSERT INTO table1
SELECT  col1, col2
FROM    table2

This WOULD NOT work (value for col2 is not specified):

INSERT INTO table1
SELECT  col1
FROM    table2

I'm using MS SQL Server. I don't know how other RDMS work.

Your solutions are correct but unnecessary complicated. You can use pure javascript filter function. This is your model:

     $scope.fishes = [{category:'freshwater', id:'1', name: 'trout', more:'false'},  {category:'freshwater', id:'2', name:'bass', more:'false'}];

And this is your function:

     $scope.showdetails = function(fish_id){
         var found = $scope.fishes.filter({id : fish_id});
         return found;
     };

You can also use expression:

     $scope.showdetails = function(fish_id){
         var found = $scope.fishes.filter(function(fish){ return fish.id === fish_id });
         return found;
     };

How do I print out my $ids and $nIds?

print "$ids\n";
print "$nIds\n";

I tried simply print $ids, but Perl complains.

Complains about what? Uninitialised value? Perhaps your loop was never entered due to an error opening the file. Be sure to check if open returned an error, and make sure you are using use strict; use warnings;.

my ($ids, $nIds) is a list, right? With two elements?

It's a (very special) function call. $ids,$nIds is a list with two elements.

For that ratio of read/writes I would guess InnoDB will perform better. Since you are fine with dirty reads, you might (if you afford) replicate to a slave and let all your reads go to the slave. Also, consider inserting in bulk, rather than one record at a time.

First change the array to a string by using implode() function. E.g $number=array(1,2,3,4,5,...); $stringofnumber=implode("|",$number); then pass the string to a session. e.g $_SESSION['string']=$stringofnumber; so when you go to the page where you want to use the array, just explode your string. e.g $number=explode("|", $_SESSION['string']); finally number is your array but remember to start array on the of each page.

I was able to achieve this with the following :

Swift 3

override func didMoveToParentViewController(parent: UIViewController?) {
   super.didMoveToParentViewController(parent)

   if parent == nil {
      println("Back Button pressed.")
      delegate?.goingBack()
   }           
}

Swift 4

override func didMove(toParent parent: UIViewController?) {
    super.didMove(toParent: parent)

    if parent == nil {
        debugPrint("Back Button pressed.")
    }
}

No need of custom back button.

It happens that I'm just starting to learn coding and I needed something similar as you have just asked in SQLite (I´m using [SQLiteStudio] (3.1.1)).

It happens that you must define the column's 'Constraint' as 'Not Null' then entering your desired definition using 'Default' 'Constraint' or it will not work (I don't know if this is an SQLite or the program requirment).

Here is the code I used:

CREATE TABLE <MY_TABLE> (
<MY_TABLE_KEY>       INTEGER    UNIQUE
                                PRIMARY KEY,
<MY_TABLE_SERIAL>    TEXT       DEFAULT (<MY_VALUE>) 
                                NOT NULL
<THE_REST_COLUMNS>
);

for linux (bash) following code works for me:

System.out.print("\033[31mERROR  \033[0m");

the \033[31m will switch the color to red and \033[0m will switch it back to normal.

From Wikipedia (I think that would make a really good answer for the interviewer :P)

Threads differ from traditional multitasking operating system processes in that:

• processes are typically independent, while threads exist as subsets of a process
• processes carry considerable state information, whereas multiple threads within a process share state as well as memory and other resources
• processes have separate address spaces, whereas threads share their address space
• processes interact only through system-provided inter-process communication mechanisms.
• Context switching between threads in the same process is typically faster than context switching between processes.

Usually it happen in TochableHighlight. Anyway error mean that you must used single element inside the whatever component.

Solution : You can use single view inside parent and anything can be used inside that View. See the attached picture

It depends on how correct you want to be. \n will usually do the job. If you really want to get it right, you look up the newline character in the os package. (It's actually called linesep.)

Note: when writing to files using the Python API, do not use the os.linesep. Just use \n; Python automatically translates that to the proper newline character for your platform.

The apps UI only works for panels.

The best you can do is to draw a button yourself and put that into your spreadsheet. Than you can add a macro to it.

Go into "Insert > Drawing...", Draw a button and add it to the spreadsheet. Than click it and click "assign Macro...", then insert the name of the function you wish to execute there. The function must be defined in a script in the spreadsheet.

Alternatively you can also draw the button somewhere else and insert it as an image.

No, not exactly. But it can inherit from a class and implement one or more interfaces.

Clear terminology is important when discussing concepts like this. One of the things that you'll see mark out Jon Skeet's writing, for example, both here and in print, is that he is always precise in the way he decribes things.

Here's a simple example that simply returns the last line without need to sort anything from any column:

"SELECT * FROM TableName ORDER BY rowid DESC LIMIT 1;"       

The answer is simpler than people are making it.

There's no technical advantage either way, and "x is not y" is what everybody else uses, which makes it the clear winner. It doesn't matter that it "looks more like English" or not; everyone uses it, which means every user of Python--even Chinese users, whose language Python looks nothing like--will understand it at a glance, where the slightly less common syntax will take a couple extra brain cycles to parse.

Don't be different just for the sake of being different, at least in this field.

For the record, the spring.jpa.hibernate.ddl-auto property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto.

The values create, create-drop, validate, and update basically influence how the schema tool management will manipulate the database schema at startup.

For example, the update operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.

The update operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.

Typically in test case scenarios, you'll likely use create-drop so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.

In development, it's often common to see developers use update to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.

In production, it's often highly recommended you use none or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.
