The ISO 8601 time format does not store a time zone name, only the corresponding UTC offset is preserved.
To convert a file ctime to an ISO 8601 time string while preserving the UTC offset in Python 3:
>>> import os
>>> from datetime import datetime, timezone
>>> ts = os.path.getctime(some_file)
>>> dt = datetime.fromtimestamp(ts, timezone.utc)
>>> dt.astimezone().isoformat()
'2015-11-27T00:29:06.839600-05:00'
The code assumes that your local timezone is Eastern Time Zone (ET) and that your system provides a correct UTC offset for the given POSIX timestamp (ts
), i.e., Python has access to a historical timezone database on your system or the time zone had the same rules at a given date.
If you need a portable solution; use the pytz
module that provides access to the tz database:
>>> import os
>>> from datetime import datetime
>>> import pytz # pip install pytz
>>> ts = os.path.getctime(some_file)
>>> dt = datetime.fromtimestamp(ts, pytz.timezone('America/New_York'))
>>> dt.isoformat()
'2015-11-27T00:29:06.839600-05:00'
The result is the same in this case.
If you need the time zone name/abbreviation/zone id, store it separately.
>>> dt.astimezone().strftime('%Y-%m-%d %H:%M:%S%z (%Z)')
'2015-11-27 00:29:06-0500 (EST)'
Note: no, :
in the UTC offset and EST
timezone abbreviation is not part of the ISO 8601 time format. It is not unique.
Different libraries/different versions of the same library may use different time zone rules for the same date/timezone. If it is a future date then the rules might be unknown yet. In other words, the same UTC time may correspond to a different local time depending on what rules you use -- saving a time in ISO 8601 format preserves UTC time and the local time that corresponds to the current time zone rules in use on your platform. You might need to recalculate the local time on a different platform if it has different rules.
Use g++ -std=c++11 -o <output_file_name> <file_to_be_compiled>
Since this must have an input element as a parent, you could just use
<input type="text" ng-model="foo" ng-change="myOnChangeFunction()">
Alternatively, you could use the ngModelController
and add a function to $formatters
, which executes functions on input change. See http://docs.angularjs.org/api/ng.directive:ngModel.NgModelController
.directive("myDirective", function() {
return {
restrict: 'A',
require: 'ngModel',
link: function(scope, element, attr, ngModel) {
ngModel.$formatters.push(function(value) {
// Do stuff here, and return the formatted value.
});
};
};
If you need to write line by line from string builder
StringBuilder sb = new StringBuilder();
sb.AppendLine("New Line!");
using (var sw = new StreamWriter(@"C:\MyDir\MyNewTextFile.txt", true))
{
sw.Write(sb.ToString());
}
If you need to write all text as single line from string builder
StringBuilder sb = new StringBuilder();
sb.Append("New Text line!");
using (var sw = new StreamWriter(@"C:\MyDir\MyNewTextFile.txt", true))
{
sw.Write(sb.ToString());
}

Go into Xcode 12 preferences Click locations Select Xcode 12 for Developer tools/command line tools Install cocoapods for Xcode 12: sudo gem install cocoapods
You have 4 columns A,B,C,D
Here is a better way to select the columns you need for the new dataframe:-
df2 = df1[['A','D']]
if you wish to use column numbers instead, use:-
df2 = df1[[0,3]]
There isn't a good example of this yet, but you can do it yourself using the native tools for each platform:

To get cookies expire time, use this simple method.
<?php
//#############PART 1#############
//expiration time (a*b*c*d) <- change D corresponding to number of days for cookie expiration
$time = time()+(60*60*24*365);
$timeMemo = (string)$time;
//sets cookie with expiration time defined above
setcookie("testCookie", "" . $timeMemo . "", $time);
//#############PART 2#############
//this function will convert seconds to days.
function secToDays($sec){
return ($sec / 60 / 60 / 24);
}
//checks if cookie is set and prints out expiration time in days
if(isset($_COOKIE['testCookie'])){
echo "Cookie is set<br />";
if(round(secToDays((intval($_COOKIE['testCookie']) - time())),1) < 1){
echo "Cookie will expire today.";
}else{
echo "Cookie will expire in " . round(secToDays((intval($_COOKIE['testCookie']) - time())),1) . " day(s)";
}
}else{
echo "not set...";
}
?>
You need to keep Part 1 and Part 2 in different files, otherwise you will get the same expire date everytime.
You can use the MAX aggregate, it would still work. MAX of one value = that value..
In this case, you could also self join 5 times on customerid, filter by dbColumnName per table reference. It may work out better.
SELECT COUNT(job_id) FROM jobs WHERE posted_date < NOW()-30;
Now()
returns the current Date and Time.

string[] strarr = {"ram","mohan","sita"};
#include <string>
std::string strarr = { "ram", "mohan", "sita" };
or
const char* strarr[] = { "ram", "mohan", "sita" };
foreach(string str in strarr) { listbox.items.add(str); }
for (int i = 0; i < sizeof strarr / sizeof *strarr; ++i)
listbox.items.add(strarr[i]);
Note: you can also put the strings into a std::vector rather than an array:
std::vector<std::string> strvec;
strvec.push_back("ram");
strvec.push_back("mohan");
strvec.push_back("sita");
for (std::vector<std::string>::const_iterator i = strvec.begin(); i != strvec.end(); ++i)

A bit shorter answer since PHP >= 5.3.0:
$csvFile = file('../somefile.csv');
$data = [];
foreach ($csvFile as $line) {
$data[] = str_getcsv($line);
}
This is only possible with setting a http response header by the server side code. Namely;
Content-Disposition: attachment; filename=fname.ext
I just had to update legacy Weblogic 8 app to use a data-source instead of hard-coded JDBC string. Datasource JNDI name on the configuration tab in the Weblogic admin showed: "weblogic.jdbc.ESdatasource", below are two ways that worked:
Context ctx = new InitialContext();
DataSource dataSource;
try {
dataSource = (DataSource) ctx.lookup("weblogic.jdbc.ESdatasource");
response.getWriter().println("A " +dataSource);
}catch(Exception e) {
response.getWriter().println("A " + e.getMessage() + e.getCause());
}
//or
try {
dataSource = (DataSource) ctx.lookup("weblogic/jdbc/ESdatasource");
response.getWriter().println("F "+dataSource);
}catch(Exception e) {
response.getWriter().println("F " + e.getMessage() + e.getCause());
}
//use your datasource
conn = datasource.getConnection();
That's all folks. No passwords and initial context factory needed from the inside of Weblogic app.
Other possible way is:
echo "text" | tee -a filename >/dev/null
The -a
will append at the end of the file.
If needing sudo
, use:
echo "text" | sudo tee -a filename >/dev/null
Check your entitlements against your app bundle id. It is probable it is not the same.
The way this still do not work is when I export for testing in my device but in Release mode.
That work to me.
Edit:
Are you trying to do sth like this? See: http://twitter.github.com/bootstrap/javascript.html#tabs
See the working example: http://jsfiddle.net/U6aKT/
<a href="#id">go to id</a>
<div style="margin-top:2000px;"></div>
<a id="id">id</a>
As a further useful solution for those of you on Windows 7 and above - if you use:
C:\Program Files\Java>mklink /D jdk8 jdk1.8.0_25
you get a Symbolic Link
folder that can be adjusted whenever a new JDK comes out.
All you need to do then is set your
netbeans_jdkhome="C:\Program Files\Java\jdk8"
(in both locations for Netbeans 8) and you never have to edit the config again. Just tweak the symlink each time your JDK is updated.
JWTs can be either signed, encrypted or both. If a token is signed, but not encrypted, everyone can read its contents, but when you don't know the private key, you can't change it. Otherwise, the receiver will notice that the signature won't match anymore.
Answer to your comment: I'm not sure if I understand your comment the right way. Just to be sure: do you know and understand digital signatures? I'll just briefly explain one variant (HMAC, which is symmetrical, but there are many others).
Let's assume Alice wants to send a JWT to Bob. They both know some shared secret. Mallory doesn't know that secret, but wants to interfere and change the JWT. To prevent that, Alice calculates Hash(payload + secret)
and appends this as signature.
When receiving the message, Bob can also calculate Hash(payload + secret)
to check whether the signature matches.
If however, Mallory changes something in the content, she isn't able to calculate the matching signature (which would be Hash(newContent + secret)
). She doesn't know the secret and has no way of finding it out.
This means if she changes something, the signature won't match anymore, and Bob will simply not accept the JWT anymore.
Let's suppose, I send another person the message {"id":1}
and sign it with Hash(content + secret)
. (+ is just concatenation here). I use the SHA256 Hash function, and the signature I get is: 330e7b0775561c6e95797d4dd306a150046e239986f0a1373230fda0235bda8c
. Now it's your turn: play the role of Mallory and try to sign the message {"id":2}
. You can't because you don't know which secret I used. If I suppose that the recipient knows the secret, he CAN calculate the signature of any message and check if it's correct.
Here's a trick if you want constants and don't care their values:
Just define empty classes.
e.g:
class RED:
pass
class BLUE:
pass
You have to workaround this via static application context accessor approach:
@Component
public class StaticContextAccessor {
private static StaticContextAccessor instance;
@Autowired
private ApplicationContext applicationContext;
@PostConstruct
public void registerInstance() {
instance = this;
}
public static <T> T getBean(Class<T> clazz) {
return instance.applicationContext.getBean(clazz);
}
}
Then you can access bean instances in a static manner.
public class Boo {
public static void randomMethod() {
StaticContextAccessor.getBean(Foo.class).doStuff();
}
}
Maybe I read the problem wrong, but I believe you already have inserted the course 11 records and simply need to update those that meet the criteria you listed with course 6's data.
If this is the case, you'll want to use an UPDATE
...FROM
statement:
UPDATE MyTable
SET
complete = 1,
complete_date = newdata.complete_date,
post_score = newdata.post_score
FROM
(
SELECT
userID,
complete_date,
post_score
FROM MyTable
WHERE
courseID = 6
AND complete = 1
AND complete_date > '8/1/2008'
) newdata
WHERE
CourseID = 11
AND userID = newdata.userID
This works perfectly for me try this just put ?rel=0&autoplay=1 in the end of link

In a single inheritance case (when you subclass one class only), your new class inherits methods of the base class. This includes __init__
. So if you don't define it in your class, you will get the one from the base.
Things start being complicated if you introduce multiple inheritance (subclassing more than one class at a time). This is because if more than one base class has __init__
, your class will inherit the first one only.
In such cases, you should really use super
if you can, I'll explain why. But not always you can. The problem is that all your base classes must also use it (and their base classes as well -- the whole tree).
If that is the case, then this will also work correctly (in Python 3 but you could rework it into Python 2 -- it also has super
):
class A:
def __init__(self):
print('A')
super().__init__()
class B:
def __init__(self):
print('B')
super().__init__()
class C(A, B):
pass
C()
#prints:
#A
#B
Notice how both base classes use super
even though they don't have their own base classes.
What super
does is: it calls the method from the next class in MRO (method resolution order). The MRO for C
is: (C, A, B, object)
. You can print C.__mro__
to see it.
So, C
inherits __init__
from A
and super
in A.__init__
calls B.__init__
(B
follows A
in MRO).
So by doing nothing in C
, you end up calling both, which is what you want.
Now if you were not using super
, you would end up inheriting A.__init__
(as before) but this time there's nothing that would call B.__init__
for you.
class A:
def __init__(self):
print('A')
class B:
def __init__(self):
print('B')
class C(A, B):
pass
C()
#prints:
#A
To fix that you have to define C.__init__
:
class C(A, B):
def __init__(self):
A.__init__(self)
B.__init__(self)
The problem with that is that in more complicated MI trees, __init__
methods of some classes may end up being called more than once whereas super/MRO guarantee that they're called just once.
In Oracle we can use below.
SELECT * FROM TABLE_A WHERE ASCIISTR(COLUMN_A) <> COLUMN_A;
You can use .attr() as a part of however you plan to toggle it:
$("button").attr("aria-expanded","true");
What about this simple code, works for me and on Windows 7

You've not shown how you're creating the string 2016-01-12T23:00:00.000Z
, but I assume via .format()
.
Anyway, .set()
is using your local time zone, but the Z
in the time string indicates zero time, otherwise known as UTC.
https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators
So I assume your local timezone is 23 hours from UTC?
saikumar's answer showed how to load the time in as UTC, but the other option is to use a .format()
call that outputs using your local timezone, rather than UTC.

Easyest solution I found: I had some < span > tags with :hover css rules in them. I switched for < a href="javascript:void(0)" > and voilà. The hover styles in iOS started working.
Another way is to call the dir()
function (see https://docs.python.org/2/library/functions.html#dir).
a = Animal()
dir(a)
>>>
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__',
'__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__',
'__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__',
'__weakref__', 'age', 'color', 'kids', 'legs', 'name', 'smell']
Note, that dir()
tries to reach any attribute that is possible to reach.
Then you can access the attributes e.g. by filtering with double underscores:
attributes = [attr for attr in dir(a)
if not attr.startswith('__')]
This is just an example of what is possible to do with dir()
, please check the other answers for proper way of doing this.
Use del /F /Q
to force deletion of read-only files (/F
) and directories and not ask to confirm (/Q
) when deleting via wildcard.
If you want to ONLY count the documents with sent_at
defined with a value of null
(don't count the documents with sent_at
not set):
db.emails.count({sent_at: { $type: 10 }})
$('#mytextbox').keydown(function (e) {
if (e.keyCode == 13) {
if (e.altKey) {
alert("alt is pressed");
}
}
});
if you press alt + enter, you will see the alert.
I had a similar issue where I would try to call reverse('admin_index')
and was constantly getting django.core.urlresolvers.NoReverseMatch
errors.
Turns out I had the old format admin urls in my urls.py file.
I had this in my urlpatterns:
(r'^admin/(.*)', admin.site.root),
which gets the admin screens working but is the deprecated way of doing it. I needed to change it to this:
(r'^admin/', include(admin.site.urls) ),
Once I did that, all the goodness that was promised in the Reversing Admin URLs docs started working.
Use element.outerHTML to get full representation of element, including outer tags and attributes.
Adding C:\Users\DELL\AppData\Roaming\npm
to System Variable Path
worked for me. Please find your appropriate file path to 'npm'
Also, check if you have added your angular-cli\bin
path to the path variable.
A mutable variable is one whose value may change in place, whereas in an immutable variable change of value will not happen in place. Modifying an immutable variable will rebuild the same variable.
git diff master...feature
shows all the new commits of your current (possibly multi-commit) feature branch.
man git-diff
documents that:
git diff A...B
is the same as:
git diff $(git merge-base A B) B
but the ...
is easier to type and remember.
As mentioned by Dave, the special case of HEAD
can be omitted. So:
git diff master...HEAD
is the same as:
git diff master...
which is enough if the current branch is feature
.
Finally, remember that order matters! Doing git diff feature...master
will show changes that are on master
not on feature
.
I wish more git commands would support that syntax, but I don't think they do. And some even have different semantics for ...
: What are the differences between double-dot ".." and triple-dot "..." in Git commit ranges?
In XML a line break is a normal character. You can do this:
<xml>
<text>some text
with
three lines</text>
</xml>
and the contents of <text>
will be
some text with three lines
If this does not work for you, you are doing something wrong. Special "workarounds" like encoding the line break are unnecessary. Stuff like \n
won't work, on the other hand, because XML has no escape sequences*.
* Note that 

is the character entity that represents a line break in serialized XML. "XML has no escape sequences" means the situation when you interact with a DOM document, setting node values through the DOM API.
This is where neither 

nor things like \n
will work, but an actual newline character will. How this character ends up in the serialized document (i.e. "file") is up to the API and should not concern you.
Since you seem to wonder where your line breaks go in HTML: Take a look into your source code, there they are. HTML ignores line breaks in source code. Use <br>
tags to force line breaks on screen.
Here is a JavaScript function that inserts <br>
into a multi-line string:
function nl2br(s) { return s.split(/\r?\n/).join("<br>"); }
Alternatively you can force line breaks at new line characters with CSS:
div.lines {
white-space: pre-line;
}
int result = 0;
bool isValidInt = int.TryParse("1234", out result);
//isValidInt should be true
//result is the integer 1234
Of course, you can check against other number types, like decimal
or double
.
If you just want to check string equality, use the == operator. Determining whether two strings are equal is simpler than finding an ordering (which is what compare() gives,) so it might be better performance-wise in your case to use the equality operator.
Longer answer: The API provides a method to check for string equality and a method to check string ordering. You want string equality, so use the equality operator (so that your expectations and those of the library implementors align.) If performance is important then you might like to test both methods and find the fastest.
If you are using IBM RAD, then ensure the to remove any j2ee.jar in your projects build path -> libraries tab, and then click on "add external jar" and select the j2ee.jar that is shipped with RAD.
Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct()
. Otherwise you get one user multiple times:
users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()
Facelets is a XML based view technology which uses XHTML+XML to generate HTML output. XML has five special characters which has special treatment by the XML parser:
<
the start of a tag.>
the end of a tag."
the start and end of an attribute value.'
the alternative start and end of an attribute value.&
the start of an entity (which ends with ;
).In case of <
, the XML parser is implicitly looking for the tag name and the end tag >
. However, in your particular case, you were using <
as a JavaScript operator, not as an XML entity. This totally explains the XML parsing error you got:
The content of elements must consist of well-formed character data or markup.
In essence, you're writing JavaScript code in the wrong place, a XML document instead of a JS file, so you should be escaping all XML special characters accordingly. The <
must be escaped as <
.
So, essentially, the
for (var i = 0; i < length; i++) {
must become
for (var i = 0; i < length; i++) {
to make it XML-valid.
However, this makes the JavaScript code harder to read and maintain. As stated in Mozilla Developer Network's excellent document Writing JavaScript for XHTML, you should be placing the JavaScript code in a character data (CDATA) block. Thus, in JSF terms, that would be:
<h:outputScript>
<![CDATA[
// ...
]]>
</h:outputScript>
The XML parser will interpret the block's contents as "plain vanilla" character data and not as XML and hence interpret the XML special characters "as-is".
But, much better is to just put the JS code in its own JS file which you include by <script src>
, or in JSF terms, the <h:outputScript>
.
<h:outputScript name="functions.js" target="head" />
This way you don't need to worry about XML-special characters in your JS code. Additional advantage is that this gives the browser the opportunity to cache the JS file so that average response size is smaller.
I might be a bit late to answer this but this will be useful for new people looking for this answer.
The answers above are good, but to have a perfect video background you have to check at the aspect ratio as the video might cut or the canvas around get deformed when resizing the screen or using it on different screen sizes.
I got into this issue not long ago and I found the solution using media queries.
Here is a tutorial that I wrote on how to create a Fullscreen Video Background with only CSS
I will add the code here as well:

I hope you find it useful.
just run mongod in terminal on the base folder if everything has been set up like installing mongo db and the client for it like mongoose. After running the command run the project file that you are working on and then the error shouldn't appear.
You may be able to use the aggregate
(or agg
) function to concatenate the values. (Untested code)
df.groupby('A')['B'].agg(lambda col: ''.join(col))
Yes that is valid syntax but it may well not do what you want.
Execution will continue after your RAISERROR
except if you add a RETURN
. So you will need to add a block with BEGIN ... END
to hold the two statements.
Also I'm not sure why you plumped for severity 15. That usually indicates a syntax error.
Finally I'd simplify the conditions using IN
CREATE PROCEDURE [dbo].[AddApplicationUser] (@TenantId BIGINT,
@UserType TINYINT,
@UserName NVARCHAR(100),
@Password NVARCHAR(100))
AS
BEGIN
IF ( @TenantId IS NULL
AND @UserType IN ( 0, 1 ) )
BEGIN
RAISERROR('The value for @TenantID should not be null',15,1);
RETURN;
END
END
The windows.load function is useful if you want to do something when everything is loaded.
$(window).load(function(){
// full load
});
But you can also use the .load function on any other element. So if you have one particularly large image and you want to do something when that loads but the rest of your page loading code when the dom has loaded you could do:
$(function(){
// Dom loaded code
$('#largeImage').load({
// Image loaded code
});
});
Also the jquery .load function is pretty much the same as a normal .onload.
Can anyone tell me the advantage of the synchronized method over the synchronized block with an example? Thanks.
There is not a clear advantage of using synchronized method over the block.
Perhaps the only one ( but I wouldn't call it an advantage ) is you don't need to include the object reference this
.
Method:
public synchronized void method() { // blocks "this" from here....
...
...
...
} // to here
Block:
public void method() {
synchronized( this ) { // blocks "this" from here ....
....
....
....
} // to here...
}
See? No advantage at all.
Blocks do have advantages over methods though, mostly in flexibility because you can use another object as lock whereas syncing the method would lock the entire object.
Compare:
// locks the whole object
...
private synchronized void someInputRelatedWork() {
...
}
private synchronized void someOutputRelatedWork() {
...
}
vs.
// Using specific locks
Object inputLock = new Object();
Object outputLock = new Object();
private void someInputRelatedWork() {
synchronized(inputLock) {
...
}
}
private void someOutputRelatedWork() {
synchronized(outputLock) {
...
}
}
Also if the method grows you can still keep the synchronized section separated:
private void method() {
... code here
... code here
... code here
synchronized( lock ) {
... very few lines of code here
}
... code here
... code here
... code here
... code here
}
May be i did not fully understand the problem, but, centering all view inside a ConstraintLayout seems very simple. This is what I used:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">
Last two lines did the trick!
Try this:
printf '\n%s\n' 'I want this on a new line!'
That allows you to separate the formatting from the actual text. You can use multiple placeholders and multiple arguments.
quantity=38; price=142.15; description='advanced widget'
$ printf '%8d%10.2f %s\n' "$quantity" "$price" "$description"
38 142.15 advanced widget
This is probably simpler than you're thinking:
int w = WIDTH_PX, h = HEIGHT_PX;
Bitmap.Config conf = Bitmap.Config.ARGB_8888; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);
// ready to draw on that bitmap through that canvas
Here's a series of tutorials I've found on the topic: Drawing with Canvas Series
The function :getargc
below may be what you're looking for.
@echo off
setlocal enableextensions enabledelayedexpansion
call :getargc argc %*
echo Count is %argc%
echo Args are %*
endlocal
goto :eof
:getargc
set getargc_v0=%1
set /a "%getargc_v0% = 0"
:getargc_l0
if not x%2x==xx (
shift
set /a "%getargc_v0% = %getargc_v0% + 1"
goto :getargc_l0
)
set getargc_v0=
goto :eof
It basically iterates once over the list (which is local to the function so the shifts won't affect the list back in the main program), counting them until it runs out.
It also uses a nifty trick, passing the name of the return variable to be set by the function.
The main program just illustrates how to call it and echos the arguments afterwards to ensure that they're untouched:
C:\Here> xx.cmd 1 2 3 4 5
Count is 5
Args are 1 2 3 4 5
C:\Here> xx.cmd 1 2 3 4 5 6 7 8 9 10 11
Count is 11
Args are 1 2 3 4 5 6 7 8 9 10 11
C:\Here> xx.cmd 1
Count is 1
Args are 1
C:\Here> xx.cmd
Count is 0
Args are
C:\Here> xx.cmd 1 2 "3 4 5"
Count is 3
Args are 1 2 "3 4 5"
You can also do like this,
(for %i in (a b "c d") do @echo %~i)
The output will be,
a
b
c d
Note that when this is put in a batch file, '%' shall be doubled.
(for %%i in (a b "c d") do @echo %%~i)
You can manually insert http header to request:
HttpGet request = new HttpGet(...);
request.setHeader("Authorization", "Basic "+Base64.encodeBytes("login:password".getBytes()));
First, give permission for execution:-
chmod +x script_name
sh script_name
bash script_name
./script_name
NOTE:-you can check if the file is executable or not by using 'ls -a'
Or much easier use SciPy
from scipy import ndimage
#rotation angle in degree
rotated = ndimage.rotate(image_to_rotate, 45)
see here for more usage info.
From the manual page:
-P prefix
--directory-prefix=prefix
Set directory prefix to prefix. The directory prefix is the
directory where all other files and sub-directories will be
saved to, i.e. the top of the retrieval tree. The default
is . (the current directory).
So you need to add -P /tmp/cron_test/
(short form) or --directory-prefix=/tmp/cron_test/
(long form) to your command. Also note that if the directory does not exist it will get created.
<ul>
<li style="color:#ddd;"><span style="color:#000;">List Item</span></li>

I was compiling in x64, just use x86 and it will solve the problem
According to Nodejs Official Page, you can install&update new node version on windows using Chocolatey or Scoop
Using(Chocolatey):
cinst nodejs
# or for full install with npm
cinst nodejs.install
Using(Scoop):
scoop install nodejs
Also you can download the Windows Installer directly from the nodejs.org web site
Something like Decimal(19,4)
usually works pretty well in most cases. You can adjust the scale and precision to fit the needs of the numbers you need to store. Even in SQL Server, I tend not to use "money
" as it's non-standard.
For a popup javascript is required. Put this in your header:
<script>
function myFunction()
{
alert("I am an alert box!"); // this is the message in ""
}
</script>
And this in your body:
<input type="button" onclick="myFunction()" value="Show alert box">
When the button is pressed a box pops up with the message set in the header.
This can be put in any html or php file without the php tags.
-----EDIT-----
To display it using php try this:
<?php echo '<script>myfunction()</script>'; ?>
It may not be 100% correct but the principle is the same.
To display different messages you can either create lots of functions or you can pass a variable in to the function when you call it.
You need to have the testng.jar
under classpath.
try C:\projectfred> java -cp "path-tojar/testng.jar:path_to_yourtest_classes" org.testng.TestNG testng.xml
Update:
Under linux I ran this command and it would be some thing similar on Windows either
test/bin# java -cp ".:../lib/*" org.testng.TestNG testng.xml
Directory structure:
/bin - All my test packages are under bin including testng.xml
/src - All source files are under src
/lib - All libraries required for the execution of tests are under this.
Once I compile all sources they go under bin directory. So, in the classpath I need to specify contents of bin directory and all the libraries like testng.xml, loggers etc over here. Also copy testng.xml to bin folder if you dont want to specify the full path where the testng.xml is available.
/bin
-- testng.xml
-- testclasses
-- Properties files if any.
/lib
-- testng.jar
-- log4j.jar
Update
:
Go to the folder MyProject
and type run the java command like the way shown below:-
java -cp ".: C:\Program Files\jbdevstudio4\studio\plugins\*" org.testng.TestNG testng.xml
I believe the testng.xml file is under C:\Users\me\workspace\MyProject
if not please give the full path for testng.xml
file
I think that Alex Martelli's answer is definitely the most elegant way to do this, but just wanted to add a way to satisfy your want for a super awesome dictionary.filter(f)
method in a Pythonic sort of way:
class FilterDict(dict):
def __init__(self, input_dict):
for key, value in input_dict.iteritems():
self[key] = value
def filter(self, criteria):
for key, value in self.items():
if (criteria(value)):
self.pop(key)
my_dict = FilterDict( {'a':(3,4), 'b':(1,2), 'c':(5,5), 'd':(3,3)} )
my_dict.filter(lambda x: x[0] < 5 and x[1] < 5)
Basically we create a class that inherits from dict
, but adds the filter method. We do need to use .items()
for the the filtering, since using .iteritems()
while destructively iterating will raise exception.
I assume you don't want to rebind the event, but call the handler.
You can use trigger()
to trigger events:
$('#billing_state_id').trigger('change');
If your handler doesn't rely on the event context and you don't want to trigger other handlers for the event, you could also name the function:
function someFunction() {
//do stuff
}
$(document).ready(function(){
//Load City by State
$('#billing_state_id').live('change', someFunction);
$('#click_me').live('click', function() {
//do something
someFunction();
});
});
Also note that live()
is deprecated, on()
is the new hotness.
You can do this by comparing each field using the NULL-safe equals operator <=>
and then negating the result using NOT
.
The complete trigger would become:
DROP TRIGGER IF EXISTS `my_trigger_name`;
DELIMITER $$
CREATE TRIGGER `my_trigger_name` AFTER UPDATE ON `my_table_name` FOR EACH ROW
BEGIN
/*Add any fields you want to compare here*/
IF !(OLD.a <=> NEW.a AND OLD.b <=> NEW.b) THEN
INSERT INTO `my_other_table` (
`a`,
`b`
) VALUES (
NEW.`a`,
NEW.`b`
);
END IF;
END;$$
DELIMITER ;
(Based on a different answer of mine.)
Without using BeanUtils or Apache Commons
public static <T1 extends Object, T2 extends Object> void copy(T1
origEntity, T2 destEntity) throws IllegalAccessException, NoSuchFieldException {
Field[] fields = origEntity.getClass().getDeclaredFields();
for (Field field : fields){
origFields.set(destEntity, field.get(origEntity));
}
}
Faced with the same issue, supporting older devices via the deprecated camera API and needing the new Camera2 API for both current devices and moving into the future; I ran into the same issues -- and have not found a 3rd party library that bridges the 2 APIs, likely because they are very different, I turned to basic OOP principals.
The 2 APIs are markedly different making interchanging them problematic for client objects expecting the interfaces presented in the old API. The new API has different objects with different methods, built using a different architecture. Got love for Google, but ragnabbit! that's frustrating.
So I created an interface focussing on only the camera functionality my app needs, and created a simple wrapper for both APIs that implements that interface. That way my camera activity doesn't have to care about which platform its running on...
I also set up a Singleton to manage the API(s); instancing the older API's wrapper with my interface for older Android OS devices, and the new API's wrapper class for newer devices using the new API. The singleton has typical code to get the API level and then instances the correct object.
The same interface is used by both wrapper classes, so it doesn't matter if the App runs on Jellybean or Marshmallow--as long as the interface provides my app with what it needs from either Camera API, using the same method signatures; the camera runs in the App the same way for both newer and older versions of Android.
The Singleton can also do some related things not tied to the APIs--like detecting that there is indeed a camera on the device, and saving to the media library.
I hope the idea helps you out.
Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.
The function 'sum(if(col = value, 1,0)) as value ' is used. You can choose from different functions like MAX(if()) etc.
delimiter //
create procedure myPivot(
in tableA varchar(255),
in columnA varchar(255),
in tableB varchar(255),
in columnB varchar(255)
)
begin
set @sql = NULL;
set @sql = CONCAT('select group_concat(distinct concat(
\'SUM(IF(',
columnA,
' = \'\'\',',
columnA,
',\'\'\', 1, 0)) AS \'\'\',',
columnA,
',\'\'\'\') separator \', \') from ',
tableA, ' into @sql');
-- select @sql;
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
-- select @sql;
SET @sql = CONCAT('SELECT p.',
columnB,
', ',
@sql,
' FROM ', tableB, ' p GROUP BY p.',
columnB,'');
-- select @sql;
/* */
PREPARE stmt FROM @sql;
EXECUTE stmt;
/* */
DEALLOCATE PREPARE stmt;
end//
delimiter ;
Usually, we define classes for this.
class XClass( object ):
def __init__( self ):
self.myAttr= None
x= XClass()
x.myAttr= 'magic'
x.myAttr
However, you can, to an extent, do this with the setattr
and getattr
built-in functions. However, they don't work on instances of object
directly.
>>> a= object()
>>> setattr( a, 'hi', 'mom' )
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'object' object has no attribute 'hi'
They do, however, work on all kinds of simple classes.
class YClass( object ):
pass
y= YClass()
setattr( y, 'myAttr', 'magic' )
y.myAttr
You are trying access a non-static class in a static way. Change Builder
to static class Builder
and it should work.
The example usage you give fails because there is no instance of Builder
present. A static class for all practical purposes is always instantiated. If you don't make it static, you'd need to say:
Widget = new Widget.Builder(10).setparm1(1).setparm2(3).build();
Because you would need to construct a new Builder
every time.
In my opinion that is easiest and fastest way:
$ npm -v
4.2.0
$ npm install -g npm@latest-3
...
$ npm -v
3.10.10
let is functional as its essentially a Proc. Also its cached.
One gotcha I found right away with let... In a Spec block that is evaluating a change.
let(:object) {FactoryGirl.create :object}
expect {
post :destroy, id: review.id
}.to change(Object, :count).by(-1)
You'll need to be sure to call let
outside of your expect block. i.e. you're calling FactoryGirl.create
in your let block. I usually do this by verifying the object is persisted.
object.persisted?.should eq true
Otherwise when the let
block is called the first time a change in the database will actually happen due to the lazy instantiation.
Update
Just adding a note. Be careful playing code golf or in this case rspec golf with this answer.
In this case, I just have to call some method to which the object responds. So I invoke the _.persisted?
_ method on the object as its truthy. All I'm trying to do is instantiate the object. You could call empty? or nil? too. The point isn't the test but bringing the object ot life by calling it.
So you can't refactor
object.persisted?.should eq true
to be
object.should be_persisted
as the object hasn't been instantiated... its lazy. :)
Update 2
leverage the let! syntax for instant object creation, which should avoid this issue altogether. Note though it will defeat a lot of the purpose of the laziness of the non banged let.
Also in some instances you might actually want to leverage the subject syntax instead of let as it may give you additional options.
subject(:object) {FactoryGirl.create :object}
@Adam Rosenfield's solution, although correct, could be implemented with a more lightweight circular_buffer
structure that does not invlove count
and capacity
.
The structure could only hold the following 4 pointers:
buffer
: Points to the start of the buffer in memory.buffer_end
: Points to the end of the buffer in memory.head
: Points to the end of stored data.tail
: Points to the start of stored data.We could keep the sz
attribute to allow the parametrisation of the unit of storage.
Both the count
and the capacity
values should be derive-able using the above pointers.
capacity
is straight forward, as it can be derived by dividing the distance between the buffer_end
pointer and the buffer
pointer by the unit of storage sz
(snippet below is pseudocode):
capacity = (buffer_end - buffer) / sz
For count though, things get a bit more complicated. For example, there is no way to determine whether the buffer is empty or full, in the scenario of head
and tail
pointing to the same location.
To tackle that, the buffer should allocate memory for an additional element. For example, if the desired capacity of our circular buffer is 10 * sz
, then we need to allocate 11 * sz
.
Capacity formula will then become (snippet below is pseudocode):
capacity_bytes = buffer_end - buffer - sz
capacity = capacity_bytes / sz
This extra element semantic allows us to construct conditions that evaluate whether the buffer is empty or full.
In order for the buffer to be empty, the head
pointer points to the same location as the tail
pointer:
head == tail
If the above evaluates to true, the buffer is empty.
In order for the buffer to be full, the head
pointer should be 1 element behind the tail
pointer. Thus, the space needed to cover in order to jump from the head
location to the tail
location should be equal to 1 * sz
.
tail
is larger that head
:tail - head == sz
If the above evaluates to true, the buffer is full.
head
is larger that tail
:buffer_end - head
returns the space to jump from the head
to the end of the buffer.tail - buffer
returns the space needed to jump from the start of the buffer to the `tail.head
to the tail
1 * sz
(buffer_end - head) + (tail - buffer) == sz
=> buffer_end - buffer - head + tail == sz
=> buffer_end - buffer - sz == head - tail
=> head - tail == buffer_end - buffer - sz
=> head - tail == capacity_bytes
If the above evaluates to true, the buffer is full.
Modifying @Adam Rosenfield's to use the above circular_buffer
structure:
#include <string.h>
#define CB_SUCCESS 0 /* CB operation was successful */
#define CB_MEMORY_ERROR 1 /* Failed to allocate memory */
#define CB_OVERFLOW_ERROR 2 /* CB is full. Cannot push more items. */
#define CB_EMPTY_ERROR 3 /* CB is empty. Cannot pop more items. */
typedef struct circular_buffer {
void *buffer;
void *buffer_end;
size_t sz;
void *head;
void *tail;
} circular_buffer;
int cb_init(circular_buffer *cb, size_t capacity, size_t sz) {
const int incremented_capacity = capacity + 1; // Add extra element to evaluate count
cb->buffer = malloc(incremented_capacity * sz);
if (cb->buffer == NULL)
return CB_MEMORY_ERROR;
cb->buffer_end = (char *)cb->buffer + incremented_capacity * sz;
cb->sz = sz;
cb->head = cb->buffer;
cb->tail = cb->buffer;
return CB_SUCCESS;
}
int cb_free(circular_buffer *cb) {
free(cb->buffer);
return CB_SUCCESS;
}
const int _cb_length(circular_buffer *cb) {
return (char *)cb->buffer_end - (char *)cb->buffer;
}
int cb_push_back(circular_buffer *cb, const void *item) {
const int buffer_length = _cb_length(cb);
const int capacity_length = buffer_length - cb->sz;
if ((char *)cb->tail - (char *)cb->head == cb->sz ||
(char *)cb->head - (char *)cb->tail == capacity_length)
return CB_OVERFLOW_ERROR;
memcpy(cb->head, item, cb->sz);
cb->head = (char*)cb->head + cb->sz;
if(cb->head == cb->buffer_end)
cb->head = cb->buffer;
return CB_SUCCESS;
}
int cb_pop_front(circular_buffer *cb, void *item) {
if (cb->head == cb->tail)
return CB_EMPTY_ERROR;
memcpy(item, cb->tail, cb->sz);
cb->tail = (char*)cb->tail + cb->sz;
if(cb->tail == cb->buffer_end)
cb->tail = cb->buffer;
return CB_SUCCESS;
}
Count character occurrences in a string is easy:
#include <bits/stdc++.h>
using namespace std;
int main()
{
string s="Sakib Hossain";
int cou=count(s.begin(),s.end(),'a');
cout<<cou;
}
If you set the the index than the dictionary will result in unique key value pairs
encoder=LabelEncoder()
df['airline_enc']=encoder.fit_transform(df['airline'])
dictAirline= df[['airline_enc','airline']].set_index('airline_enc').to_dict()
You could use Jobcopy Builder plugin
Your data type is DECIMAL with decimal places, say DECIMAL(10,2). The values in your database are 12, 15, 18, and 20.
12 is the same as 12.0 and 12.00 and 12.000 . It is up to the tool you are using to select the data with, how to display the numbers. Yours either defaults to two digits for decimals or it takes the places from your data definition.
If you only want integers in your column, then change its data type to INT. It makes no sense to use DECIMAL then.
If you want integers and decimals in that column then stay with the DECIMAL type. If you don't like the way you are shown the values, then format them in your application. It's up to that client program to decide for instance if to display point or comma for the decimal separator. (The database can be used from different locations.)
Also don't rely on any database or session settings like a decimal separator being a point and not a comma and then use REPLACE on it. That can work for one person and not for the other.
Using https sounds best option here (certificates are not that expensive nowadays). However if http is a requirement, you may use some encription - encript it on server side and decript in users browser (send key separately).
We have used that while implementing safevia.net - encription is done on clients (sender/receiver) sides, so users data are not available on network nor server layer.
You need to call newTest
to make the functions declared inside that method “visible” (see Functions within functions). But that are then just normal functions and no methods.
Try using TempData
:
public ActionResult Create(FormCollection collection) {
...
TempData["notice"] = "Successfully registered";
return RedirectToAction("Index");
...
}
Then, in your Index view, or master page, etc., you can do this:
<% if (TempData["notice"] != null) { %>
<p><%= Html.Encode(TempData["notice"]) %></p>
<% } %>
Or, in a Razor view:
@if (TempData["notice"] != null) {
<p>@TempData["notice"]</p>
}
Quote from MSDN (page no longer exists as of 2014, archived copy here):
An action method can store data in the controller's TempDataDictionary object before it calls the controller's RedirectToAction method to invoke the next action. The TempData property value is stored in session state. Any action method that is called after the TempDataDictionary value is set can get values from the object and then process or display them. The value of TempData persists until it is read or until the session times out. Persisting TempData in this way enables scenarios such as redirection, because the values in TempData are available beyond a single request.
Because QuerySets implement the Python __or__
operator (|
), or union, it just works. As you'd expect, the |
binary operator returns a QuerySet
so order_by()
, .distinct()
, and other queryset filters can be tacked on to the end.
combined_queryset = User.objects.filter(income__gte=5000) | User.objects.filter(income__isnull=True)
ordered_queryset = combined_queryset.order_by('-income')
Update 2019-06-20: This is now fully documented in the Django 2.1 QuerySet API reference. More historic discussion can be found in DjangoProject ticket #21333.
Use the CSS property white-space: nowrap and overflow: hidden on your td.
Just saw your comment, not sure what I was thinking, I've done this so many times I forgot how I do it. This is approach that works well in most browsers for me... rather than trying to constrain the td, I use a div inside the td that will handle the overflow instance. This has a nice side effect of being able to add your padding, margins, background colors, etc. to your div rather than trying to style the td.
<html>
<head>
<style>
.hideextra { white-space: nowrap; overflow: hidden; text-overflow:ellipsis; }
</style>
</head>
<body>
<table style="width: 300px">
<tr>
<td>Column 1</td><td>Column 2</td>
</tr>
<tr>
<td>
<div class="hideextra" style="width:200px">
this is the text in column one which wraps</div></td>
<td>
<div class="hideextra" style="width:100px">
this is the column two test</div></td>
</tr>
</table>
</body>
</html>
As a bonus, IE will place an ellipsis in the case of an overflow using the browser-specific text-overflow:ellipsis style. There is a way to do the same in FireFox automatically too, but I have not tested it myself.
I started using this truncation code by Justin Maxwell for several months now which works properly in FireFox too.
You can simply set the window state
this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
I've used this function several times:
public static bool IsNumeric(object Expression)
{
double retNum;
bool isNum = Double.TryParse(Convert.ToString(Expression), System.Globalization.NumberStyles.Any, System.Globalization.NumberFormatInfo.InvariantInfo, out retNum);
return isNum;
}
But you can also use;
bool b1 = Microsoft.VisualBasic.Information.IsNumeric("1"); //true
bool b2 = Microsoft.VisualBasic.Information.IsNumeric("1aa"); // false

This is an html5 error like has been said, you can still have the button as a submit (if you want to cover both javascript and non javascript users) using it like:
<button type="submit" onclick="return false"> Register </button>
This way you will cancel the submit but still do whatever you are doing in jquery or javascript function`s and do the submit for users who dont have javascript.

Not sure what kind of text box you are refering to. However, I'm not sure if you can do this in a text box on a user form.
A text box on a sheet you can though.
Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Text = "R2=" & variable
Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Characters(2, 1).Font.Superscript = msoTrue
And same thing for an excel cell
Sheets("Sheet1").Range("A1").Characters(2, 1).Font.Superscript = True
If this isn't what you're after you will need to provide more information in your question.
EDIT: posted this after the comment sorry
var request = require('request');
request.post('http://localhost/test2.php',

If you are using VideoView or heavy weight widgets in your childviews keep your RecyclerView with height wrap_content
inside a NestedScrollView with height match_parent
Then scrolling will work smooth as perfectly as you want it.
FYI,
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:nestedScrollingEnabled="false"
android:layout_height="wrap_content"
android:clipToPadding="false" />
</android.support.v4.widget.NestedScrollView>
Thanks Micro this was from your hint!

This works for me without throwing an exception:

import java.util.Date;
public class Sandbox {
public static void main(String[] args) throws ParseException {
SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
Date parsed = format.parse("20110210");
java.sql.Date sql = new java.sql.Date(parsed.getTime());
}
}
You either missed @Entity on class definition or you have explicit component scan path and this path does not contain your class

I would support the idea of creating a ftp group that will have the rights to upload. However, i don't think it is necessary to give 775 permission. 7 stands for read, write, execute. Normally you want to allow certain groups to read and write, but depending on the case, execute may not be necessary.

Also from Java doc:
java.lang
Class Process
Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.
Fail to clear the buffer of input stream (which pipes to the output stream of subprocess) from Process may lead to a subprocess blocking.
Try this:
Process process = Runtime.getRuntime().exec("tasklist");
BufferedReader reader =
new BufferedReader(new InputStreamReader(process.getInputStream()));
while ((reader.readLine()) != null) {}
process.waitFor();
Destructors provide an implicit way of freeing unmanaged resources encapsulated in your class, they get called when the GC gets around to it and they implicitly call the Finalize method of the base class. If you're using a lot of unmanaged resources it is better to provide an explicit way of freeing those resources via the IDisposable interface. See the C# programming guide: http://msdn.microsoft.com/en-us/library/66x5fx1b.aspx
Using a data attribute on an HTML element avoids having to use inline scripting, which in turn means you can use stricter CSP rules for increased security.
Specify a data attribute like so:
<div id="mydiv" data-geocode='{{ geocode|tojson }}'>...</div>
Then access it in a static JavaScript file like so:
// Raw JavaScript
var geocode = JSON.parse(document.getElementById("mydiv").dataset.geocode);
// jQuery
var geocode = JSON.parse($("#mydiv").data("geocode"));
Better Approach:
<script type="text/javascript">
$('#btn').click(function() {
var id = $(this).attr('id');
alert(id);
});
</script>
<input id="btn" type="button" value="click" />
But, if you REALLY need to do the click handler inline, this will work:
<script type="text/javascript">
function display(el) {
var id = $(el).attr('id');
alert(id);
}
</script>
<input id="btn" type="button" value="click" OnClick="display(this);" />
I check for both Wi-fi and Mobile internet as follows...
private boolean haveNetworkConnection() {
boolean haveConnectedWifi = false;
boolean haveConnectedMobile = false;
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] netInfo = cm.getAllNetworkInfo();
for (NetworkInfo ni : netInfo) {
if (ni.getTypeName().equalsIgnoreCase("WIFI"))
if (ni.isConnected())
haveConnectedWifi = true;
if (ni.getTypeName().equalsIgnoreCase("MOBILE"))
if (ni.isConnected())
haveConnectedMobile = true;
}
return haveConnectedWifi || haveConnectedMobile;
}
Obviously, It could easily be modified to check for individual specific connection types, e.g., if your app needs the potentially higher speeds of Wi-fi to work correctly etc.
Now you can do in swift the following thing which allows you to regain a little bit of the objective-c if nil else
if textfieldDate.text?.isEmpty ?? true {
}
I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.
public abstract class ExternalScript extends Script {
private String source;
public void setSource(String file) {
source = file;
}
public String getSource() {
return source;
}
}
Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:
Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.
Simply use _.uniqBy(). It creates duplicate-free version of an array.
This is a new way and available from 4.0.0 version.
_.uniqBy(data, 'id');
or
_.uniqBy(data, obj => obj.id);
Does this work?

Also, what version of php are you using?
If you are using beeline
to connect to hive, then !dbinfo
will give all the underlying database details and in the output getDatabaseProductVersion
will have the hive database version.
Sample output:

begin
x := myfunc(myargs);
end;
Alternatively:
select myfunc(myargs) from dual;
getView()
method in Adapter is for generating item's view of a ListView
, Gallery
,...
LayoutInflater
is used to get the View object which you define in a layout xml (the root object, normally a LinearLayout
,
FrameLayout
, or RelativeLayout
)
convertView
is for recycling. Let's say you have a listview which can only display 10 items at a time, and currently it is
displaying item 1 -> item 10. When you scroll down one item, the
item 1 will be out of screen, and item 11 will be displayed. To
generate View for item 11, the getView() method will be called, and
convertView
here is the view of item 1 (which is not neccessary
anymore). So instead create a new View object for item 11 (which is
costly), why not re-use convertView
? => we just check convertView
is
null or not, if null create new view, else re-use convertView
.
parentView
is the ListView or Gallery... which contains the item's view which getView()
generates.
Note: you don't call this method directly, just need to implement it to tell the parent view how to generate the item's view.
To work off the answer above (https://stackoverflow.com/a/44860918/2011818), you can also send the objects inline the "To" inside the Link object.
<Route path="/foo/:fooId" component={foo} / >
<Link to={{pathname:/foo/newb, sampleParam: "Hello", sampleParam2: "World!" }}> CLICK HERE </Link>
this.props.match.params.fooId //newb
this.props.location.sampleParam //"Hello"
this.props.location.sampleParam2 //"World!"
Above mentioned answers are correct but what if you are doing a heavy process after losing the focus from the relevant component. For that, I came with a solution with two flags where the focus out event process will only take place when losing the focus from relevant component only.
isFocusInsideComponent = false;
isComponentClicked = false;
@HostListener('click')
clickInside() {
this.isFocusInsideComponent = true;
this.isComponentClicked = true;
}
@HostListener('document:click')
clickout() {
if (!this.isFocusInsideComponent && this.isComponentClicked) {
// do the heavy process
this.isComponentClicked = false;
}
this.isFocusInsideComponent = false;
}
Hope this will help you. Correct me If have missed anything.
Adding placeholder attributes from code-behind:
txtFilterTerm.Attributes.Add("placeholder", "Filter" + Filter.Name);
Or
txtFilterTerm.Attributes["placeholder"] = "Filter" + Filter.Name;
Adding placeholder attributes from aspx Page
<asp:TextBox type="text" runat="server" id="txtFilterTerm" placeholder="Filter" />
Or
<input type="text" id="txtFilterTerm" placeholder="Filter"/>
If you only have access to the view object, then you can get the parameters defined in the URL path this way:
view.kwargs.get('url_param')
If you only have access to the request object, use the following:
request.resolver_match.kwargs.get('url_param')
Tested on Django 3.
Just a quick chime in here to hopefully help others... Especially with the newer version (since this is 2 years old)...
Instead of having some static fields defined in JS, you can also use the data-rule-*
attributes. You can use built-in rules as well as custom rules.
See http://jqueryvalidation.org/documentation/#link-list-of-built-in-validation-methods for built-in rules.
Example:
<p><label>Email: <input type="text" name="email" id="email" data-rule-email="true" required></label></p>
<p><label>Confirm Email: <input type="text" name="email" id="email_confirm" data-rule-email="true" data-rule-equalTo="#email" required></label></p>
Note the data-rule-*
attributes.
the mysqli_query
excepts 2 parameters , first variable is mysqli_connect
equivalent variable , second one is the query you have provided
$name1 = mysqli_connect(localhost,tdoylex1_dork,dorkk,tdoylex1_dork);
$name2 = mysqli_query($name1,"SELECT name FROM users ORDER BY RAND() LIMIT 1");
The method argument specifies the parameter of the smooth statistic. You can see stat_smooth
for the list of all possible arguments to the method argument.

This is not something you can do in a foolproof way. One possibility would be to examine every character in the file to ensure that it doesn't contain any characters in the ranges 0x00 - 0x1f
or 0x7f -0x9f
but, as I said, this may be true for any number of files, including at least one other variant of ISO8859.
Another possibility is to look for specific words in the file in all of the languages supported and see if you can find them.
So, for example, find the equivalent of the English "and", "but", "to", "of" and so on in all the supported languages of 8859-1 and see if they have a large number of occurrences within the file.
I'm not talking about literal translation such as:
English French
------- ------
of de, du
and et
the le, la, les
although that's possible. I'm talking about common words in the target language (for all I know, Icelandic has no word for "and" - you'd probably have to use their word for "fish" [sorry that's a little stereotypical, I didn't mean any offense, just illustrating a point]).
Just in case...
If you are using SoapUI Mock Service (as the Server), calling it from a C# WCF:
WCF --> SoapUI MockService
And in this case you are getting the same error:
The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8).
Edit your Mock Response at SoapUI and add a Header to it:
In my scenario, this fix the problem.
In PHP 5.5+, you can do
function limit($iterable, $limit) {
foreach ($iterable as $key => $value) {
if (!$limit--) break;
yield $key => $value;
}
}
foreach (limit($arr, 10) as $key => $value) {
// do stuff
}
Generators rock.
The correct way from hibernate doc:
Session s = HibernateUtil.getSessionFactory().openSession();
Transaction tx = null;
try {
tx = s.beginTransaction();
// here get object
List<Employee> list = s.createCriteria(Employee.class).list();
tx.commit();
} catch (HibernateException ex) {
if (tx != null) {
tx.rollback();
}
Logger.getLogger("con").info("Exception: " + ex.getMessage());
ex.printStackTrace(System.err);
} finally {
s.close();
}
HibernateUtil code (can find at Google):
public class HibernateUtil {
private static final SessionFactory tmrSessionFactory;
private static final Ejb3Configuration tmrEjb3Config;
private static final EntityManagerFactory tmrEntityManagerFactory;
static {
try {
tmrSessionFactory = new Configuration().configure("tmr.cfg.xml").buildSessionFactory();
tmrEjb3Config = new Ejb3Configuration().configure("tmr.cfg.xml");
tmrEntityManagerFactory = tmrEjb3Config.buildEntityManagerFactory();
} catch (HibernateException ex) {
Logger.getLogger("app").log(Level.WARN, ex.getMessage());
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return tmrSessionFactory;
}
/* getters and setters here */
}
The syntax for using an alias in an update statement on SQL Server is as follows:
UPDATE Q
SET Q.TITLE = 'TEST'
FROM HOLD_TABLE Q
WHERE Q.ID = 101;
The alias should not be necessary here though.
If you're using brew
like me and wasted a lot of time searching for the infamous kafka-logs
folder, fear no more. (and please do let me know if that works for you and multiple different versions of Homebrew, Kafka etc :) )
You're probably going to find it under:
/usr/local/var/lib/kafka-logs
(this is also helpful for basically every app you install through brew)
1) brew services list
kafka started matbhz /Users/matbhz/Library/LaunchAgents/homebrew.mxcl.kafka.plist
2) Open and read that plist
you found above
3) Find the line defining server.properties
location open it, in my case:
/usr/local/etc/kafka/server.properties
4) Look for the log.dirs
line:
log.dirs=/usr/local/var/lib/kafka-logs
5) Go to that location and delete the logs for the topics you wish
6) Restart Kafka with brew services restart kafka
If you use bootstrap 4, you can hide element that way
className={this.state.hideElement ? "invisible" : "visible"}
Smoke testing is about checking if the requirements are satisfied or not. Smoke testing is a general health check up.
Sanity testing is about checking if a particular module is completely working or not. Sanity testing is specialized in particular health check up.
@Wayne Burkett's answer is good. If you wanted to also extract the alpha value to get an rgba color, we could do this:
var r = p[0], g = p[1], b = p[2], a = p[3] / 255;
var rgba = "rgb(" + r + "," + g + "," + b + "," + a + ")";
I divided the alpha value by 255 because the ImageData object stores it as an integer between 0 - 255, but most applications (for example, CanvasRenderingContext2D.fillRect()
) require colors to be in valid CSS format, where the alpha value is between 0 and 1.
(Also remember that if you extract a transparent color and then draw it back onto the canvas, it will overlay whatever color is there previously. So if you drew the color rgba(0,0,0,0.1)
over the same spot 10 times, it would be black.)
You can use a function with COALESCE.
CREATE FUNCTION [dbo].[GetAliasesById]
(
@userID int
)
RETURNS varchar(max)
AS
BEGIN
declare @output varchar(max)
select @output = COALESCE(@output + ', ', '') + alias
from UserAliases
where userid = @userID
return @output
END
GO
SELECT UserID, dbo.GetAliasesByID(UserID)
FROM UserAliases
GROUP BY UserID
GO
You can use RETURN
to stop execution of a stored procedure immediately. Quote taken from Books Online:
Exits unconditionally from a query or procedure. RETURN is immediate and complete and can be used at any point to exit from a procedure, batch, or statement block. Statements that follow RETURN are not executed.
Out of paranoia, I tried yor example and it does output the PRINTs and does stop execution immediately.
log in as root user:
sudo su
password:
then go and do what you want to do in var/www
The built-in string constructor will automatically call obj.__str__
:
''.join(map(str,list))

For those looking for a dynamic solution to embed Matplotlib in PyQt5 (even plot data using drag and drop). In PyQt5 you need to use super on the main window class to accept the drops. The dropevent function can be used to get the filename and rest is simple:
def dropEvent(self,e):
"""
This function will enable the drop file directly on to the
main window. The file location will be stored in the self.filename
"""
if e.mimeData().hasUrls:
e.setDropAction(QtCore.Qt.CopyAction)
e.accept()
for url in e.mimeData().urls():
if op_sys == 'Darwin':
fname = str(NSURL.URLWithString_(str(url.toString())).filePathURL().path())
else:
fname = str(url.toLocalFile())
self.filename = fname
print("GOT ADDRESS:",self.filename)
self.readData()
else:
e.ignore() # just like above functions
For starters the reference complete code gives this output:
You can create an std::string
#include <string>
#include <vector>
int main(int argc, char *argv[])
{
// check if there is more than one argument and use the second one
// (the first argument is the executable)
if (argc > 1)
{
std::string arg1(argv[1]);
// do stuff with arg1
}
// Or, copy all arguments into a container of strings
std::vector<std::string> allArgs(argv, argv + argc);
}
Relative : Relative to it’s current position, but can be moved. Or A RELATIVE positioned element is positioned relative to ITSELF.
Absolute : An ABSOLUTE positioned element is positioned relative to IT'S CLOSEST POSITIONED PARENT. if one is present, then it works like fixed.....relative to the window.
<div style="position:relative"> <!--2nd parent div-->
<div> <!--1st parent div-->
<div style="position:absolute;left:10px;....."> <!--Middle div-->
Md. Arif
</div>
</div>
</div>
Here, 2nd parent div
position is relative so the middle div
will changes it's position with respect to 2nd parent div
. If 1st parent div
position would relative then the Middle div
would changes it's position with respect to 1st parent div
. Details
Not saying this is the best approach, but it seems to work for me.
The full code may be found at: Example code at: https://github.com/dbleicher/recyclerview-grid-quickreturn
First off, add the expanded area to your cell/item layout, and make the enclosing cell layout animateLayoutChanges="true". This will ensure that the expand/collapse is animated:
<LinearLayout
android:id="@+id/llCardBack"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@android:color/white"
android:animateLayoutChanges="true"
android:padding="4dp"
android:orientation="vertical">
<TextView
android:id="@+id/tvTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|fill_horizontal"
android:padding="10dp"
android:gravity="center"
android:background="@android:color/holo_green_dark"
android:text="This is a long title to show wrapping of text in the view."
android:textColor="@android:color/white"
android:textSize="16sp" />
<TextView
android:id="@+id/tvSubTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|fill_horizontal"
android:background="@android:color/holo_purple"
android:padding="6dp"
android:text="My subtitle..."
android:textColor="@android:color/white"
android:textSize="12sp" />
<LinearLayout
android:id="@+id/llExpandArea"
android:visibility="gone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="6dp"
android:text="Item One" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="6dp"
android:text="Item Two" />
</LinearLayout>
</LinearLayout>
Then, make your RV Adapter class implement View.OnClickListener so that you can act on the item being clicked. Add an int field to hold the position of the one expanded view, and initialize it to a negative value:
private int expandedPosition = -1;
Finally, implement your ViewHolder, onBindViewHolder() methods and override the onClick() method. You will expand the view in onBindViewHolder if it's position is equal to "expandedPosition", and hide it if not. You set the value of expandedPosition in the onClick listener:
@Override
public void onBindViewHolder(RVAdapter.ViewHolder holder, int position) {
int colorIndex = randy.nextInt(bgColors.length);
holder.tvTitle.setText(mDataset.get(position));
holder.tvTitle.setBackgroundColor(bgColors[colorIndex]);
holder.tvSubTitle.setBackgroundColor(sbgColors[colorIndex]);
if (position == expandedPosition) {
holder.llExpandArea.setVisibility(View.VISIBLE);
} else {
holder.llExpandArea.setVisibility(View.GONE);
}
}
@Override
public void onClick(View view) {
ViewHolder holder = (ViewHolder) view.getTag();
String theString = mDataset.get(holder.getPosition());
// Check for an expanded view, collapse if you find one
if (expandedPosition >= 0) {
int prev = expandedPosition;
notifyItemChanged(prev);
}
// Set the current position to "expanded"
expandedPosition = holder.getPosition();
notifyItemChanged(expandedPosition);
Toast.makeText(mContext, "Clicked: "+theString, Toast.LENGTH_SHORT).show();
}
/**
* Create a ViewHolder to represent your cell layout
* and data element structure
*/
public static class ViewHolder extends RecyclerView.ViewHolder {
TextView tvTitle;
TextView tvSubTitle;
LinearLayout llExpandArea;
public ViewHolder(View itemView) {
super(itemView);
tvTitle = (TextView) itemView.findViewById(R.id.tvTitle);
tvSubTitle = (TextView) itemView.findViewById(R.id.tvSubTitle);
llExpandArea = (LinearLayout) itemView.findViewById(R.id.llExpandArea);
}
}
This should expand only one item at a time, using the system-default animation for the layout change. At least it works for me. Hope it helps.
double
.*gasp*
Because it can represent any 15 digit number with no constraints on where the decimal point is. All for a measly 8 bytes!
So it can represent:
0.123456789012345
123456789012345.0
...and anything in between.
This is useful because we're dealing with global currencies, and double
can store the various numbers of decimal places we'll likely encounter.
A single double
field can represent 999,999,999,999,999s in Japanese yens, 9,999,999,999,999.99s in US dollars and even 9,999,999.99999999s in bitcoins
If you try doing the same with decimal
, you need decimal(30, 15)
which costs 14 bytes.
Of course, using double
isn't without caveats.
However, it's not loss of accuracy as some tend to point out. Even though double
itself may not be internally exact to the base 10 system, we can make it exact by rounding the value we pull from the database to its significant decimal places. If needed that is. (e.g. If it's going to be outputted, and base 10 representation is required.)
The caveats are, any time we perform arithmetic with it, we need to normalize the result (by rounding it to its significant decimal places) before:
Another kind of caveat is, unlike decimal(m, d)
where the database will prevent programs from inserting a number with more than m
digits, no such validations exists with double
. A program could insert a user inputted value of 20 digits and it'll end up being silently recorded as an inaccurate amount.
Many frameworks (that you might already be using) have date formatting that you may not be aware of. jQueryUI was already mentioned, but other frameworks such as Kendo UI (Globalization), Yahoo UI (Util) and AngularJS have them as well.
// 11/6/2000
kendo.toString(new Date(value), "d")
// Monday, November 06, 2000
kendo.toString(new Date(2000, 10, 6), "D")
hi,that maybe the project's problem,
chose the project and setting you eclipse:
project -> clean...
It means not to output the respective command. Compare the following two batch files:
@echo foo
and
echo foo
The former has only foo
as output while the latter prints
H:\Stuff>echo foo
foo
(here, at least). As can be seen the command that is run is visible, too.
echo off
will turn this off for the complete batch file. However, the echo off
call itself would still be visible. Which is why you see @echo off
in the beginning of batch files. Turn off command echoing and don't echo the command turning it off.
Removing that line (or commenting it out) is often a helpful debugging tool in more complex batch files as you can see what is run prior to an error message.
From bash command line, run:
$ python -c "import nltk; nltk.download('punkt')"
Assuming staff_id + date form a uk, this is another method:
SELECT STAFF_ID, SITE_ID, PAY_LEVEL
FROM TABLE t
WHERE END_ENROLLMENT_DATE is null
AND DATE = (SELECT MAX(DATE)
FROM TABLE
WHERE staff_id = t.staff_id
AND DATE <= SYSDATE)
Here is a similiar thing that I would like to share,
while you're working on Visual Studio you could get an error like:
'scanf': function or variable may be unsafe. Consider using
scanf_s
instead. To disable deprecation, use_CRT_SECURE_NO_WARNINGS
To prevent this, you should write it in the following format
A single character may be read as follows:
char c;
scanf_s("%c", &c, 1);
When multiple characters for non-null terminated strings are read, integers are used as the width specification and the buffer size.
char c[4];
scanf_s("%4c", &c, _countof(c));
Take care with some of the examples; $0 may include some leading path as well as the name of the program. Eg save this two line script as ./mytry.sh and the execute it.
#!/bin/bash
echo "parameter 0 --> $0" ; exit 0
Output:
parameter 0 --> ./mytry.sh
This is on a current (year 2016) version of Bash, via Slackware 14.2
You can use app.run(debug=True)
for the Werkzeug Debugger edit as mentioned below, and I should have known.
Using find
's -regex
argument:
find . -regex '.*/Robert\.\(h\|cpp\)$'
Or just using -name
:
find . -name 'Robert.*' -a \( -name '*.cpp' -o -name '*.h' \)
Try out df.apply() if you've a small/medium dataframe,
df['c2'] = df.apply(lambda x: 10 if x['c1'] == 'Value' else x['c1'], axis = 1)
Else, follow the slicing techniques mentioned in the above comments if you've got a big dataframe.
When dealing with passing values from local db to server and vice versa, I was having too much trouble with ?'s and !'s and what not.
So I made a Swift3.0 utility to handle null cases and i can almost totally avoid ?'s and !'s in the code.
func str(_ string: String?) -> String {
return (string != nil ? string! : "")
}
Ex:-
Before :
let myDictionary: [String: String] =
["title": (dbObject?.title != nil ? dbObject?.title! : "")]
After :
let myDictionary: [String: String] =
["title": str(dbObject.title)]
and when its required to check for a valid string,
if !str(dbObject.title).isEmpty {
//do stuff
}
This saved me having to go through the trouble of adding and removing numerous ?'s and !'s after writing code that reasonably make sense.
React uses event delegation with a single event listener on document for events that bubble, like 'click' in this example, which means stopping propagation is not possible; the real event has already propagated by the time you interact with it in React. stopPropagation on React's synthetic event is possible because React handles propagation of synthetic events internally.
stopPropagation: function(e){
e.stopPropagation();
e.nativeEvent.stopImmediatePropagation();
}
Using standard git diff command (also good for scripting):
git diff --name-only <sha>^ <sha>
If you want also the status of the changed files:
git diff --name-status <sha>^ <sha>
This works well with merge commits.
If you have used Powershell commands to set the Proxy on windows machine doing the below helped me.
To unset the proxy use: 1. Open powershell 2. Enter the following:
[Environment]::SetEnvironmentVariable(“HTTP_PROXY”, $null, [EnvironmentVariableTarget]::Machine)
[Environment]::SetEnvironmentVariable(“HTTPS_PROXY”, $null, [EnvironmentVariableTarget]::Machine)
To set the proxy again use: 1. Open powershell 2. Enter the following:
[Environment]::SetEnvironmentVariable(“HTTP_PROXY”, “http://yourproxy.com:yourportnumber”, [EnvironmentVariableTarget]::Machine)
[Environment]::SetEnvironmentVariable(“HTTPS_PROXY”, “http://yourproxy.com:yourportnumber”, [EnvironmentVariableTarget]::Machine)
Try the following commands to search the string inside all previous tracked files:
git log --patch | less +/searching_string
or
git rev-list --all | GIT_PAGER=cat xargs git grep 'search_string'
which needs to be run from the parent directory where you'd like to do the searching.
$(function() { $( "#draggable" ).draggable({ containment: "window" }); });
of this code does not display. Full code and Demo: http://www.limitsizbilgi.com/div-tasima-surukle-birak-div-drag-and-drop-jquery.html
In order to limit the element inside its parent:

Use
git clone --depth=1 --branch=master git://someserver/somerepo dirformynewrepo
rm -rf ./dirformynewrepo/.git
dirformynewrepo
not a Git repository any more.Here are a couple of ways to do that:
I'd suggest, provide a popup asking the user if s/he wants to go full screen and then call this javascript accordingly.
You can do it with java.nio.charset.Charset.
import java.nio.charset.Charset;
public class StringUtils {
public static boolean isPureAscii(String v) {
return Charset.forName("US-ASCII").newEncoder().canEncode(v);
// or "ISO-8859-1" for ISO Latin 1
// or StandardCharsets.US_ASCII with JDK1.7+
}
public static void main (String args[])
throws Exception {
String test = "Réal";
System.out.println(test + " isPureAscii() : " + StringUtils.isPureAscii(test));
test = "Real";
System.out.println(test + " isPureAscii() : " + StringUtils.isPureAscii(test));
/*
* output :
* Réal isPureAscii() : false
* Real isPureAscii() : true
*/
}
}
I had to do it on DOM ready
$( document ).ready(function () { // this has to be done after the document has been rendered
$("[data-toggle='tooltip']").tooltip({html: true}); // enable bootstrap 3 tooltips
$('[data-toggle="popover"]').popover({
trigger: 'hover',
'placement': 'top',
'show': true
});
});
And change my load orders to be:
I'm using python 3.4, requests 2.19.1:
'urllib3' is the logger to get now (no longer 'requests.packages.urllib3'). Basic logging will still happen without setting http.client.HTTPConnection.debuglevel
I suggest you try JMapper Framework.
It is a Java bean to Java bean mapper, allows you to perform the passage of data dynamically with annotations and / or XML.
With JMapper you can:
Lift-json is at version 2.6 and it works really well (and is also very well supported, the maintainer is always ready to fix any bugs users may find. You can find examples using it on the github repository
The maintainer (Joni Freeman) is always reachable on the Lift mailing list. There are also other users on the mailing list who are very helpful as well.
As @Alexey points out, if you want to use the library with other Scala version, say 2.11.x
, change scalaVersion
and use %%
as follows:
scalaVersion := "2.11.5"
"net.liftweb" %% "lift-json" % "2.6"
You can check the liftweb.net site to find out the latest version as time goes by.
this would probably call for a many-to-many relation ship as follows
public class Person{
private Long personId;
@manytomany
private Set skills;
//Getters and setters
}
public class Skill{
private Long skillId;
private String skillName;
@manyToMany(MappedBy="skills,targetClass="Person")
private Set persons; // (people would not be a good convenion)
//Getters and setters
}
you may need to define a joinTable + JoinColumn but it will possible work also without...
Yes, you can get it from the File
object by using File.toPath()
. Keep in mind that this is only for Java 7+. Java versions 6 and below do not have it.
you can define a route in web.php
Route::get('/clear/route', 'ConfigController@clearRoute');
and make ConfigController.php like this
class ConfigController extends Controller
{
public function clearRoute()
{
\Artisan::call('route:clear');
}
}
and go to that route on server example http://your-domain/clear/route
It is possible to write to an excel file without opening it using the Microsoft.Jet.OLEDB.4.0
and OleDb
. Using OleDb
, it behaves as if you were writing to a table using sql.
Here is the code I used to create and write to an new excel file. No extra references are needed
var connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\SomePath\ExcelWorkBook.xls;Extended Properties=Excel 8.0";
using (var excelConnection = new OleDbConnection(connectionString))
{
// The excel file does not need to exist, opening the connection will create the
// excel file for you
if (excelConnection.State != ConnectionState.Open) { excelConnection.Open(); }
// data is an object so it works with DBNull.Value
object propertyOneValue = "cool!";
object propertyTwoValue = "testing";
var sqlText = "CREATE TABLE YourTableNameHere ([PropertyOne] VARCHAR(100), [PropertyTwo] INT)";
// Executing this command will create the worksheet inside of the workbook
// the table name will be the new worksheet name
using (var command = new OleDbCommand(sqlText, excelConnection)) { command.ExecuteNonQuery(); }
// Add (insert) data to the worksheet
var commandText = $"Insert Into YourTableNameHere ([PropertyOne], [PropertyTwo]) Values (@PropertyOne, @PropertyTwo)";
using (var command = new OleDbCommand(commandText, excelConnection))
{
// We need to allow for nulls just like we would with
// sql, if your data is null a DBNull.Value should be used
// instead of null
command.Parameters.AddWithValue("@PropertyOne", propertyOneValue ?? DBNull.Value);
command.Parameters.AddWithValue("@PropertyTwo", propertyTwoValue ?? DBNull.Value);
command.ExecuteNonQuery();
}
}
I was looking for the answer too and my intention was to clean every non-alpha and there shouldn't have more than one space.
So, I modified Alex's answer to this, and this is working for me
preg_replace('/[^a-z|\s+]+/i', ' ', $name)
The regex above turned sy8ed sirajul7_islam
to sy ed sirajul islam
Explanation: regex will check NOT ANY from a to z in case insensitive way or more than one white spaces, and it will be converted to a single space.
My initial solution was to resolve the above errors by installing ruby-devel
, patch
and rubygems
.
My issue was a bit different as bcrypt 3.1.11 still had issues compiling and installing on Fedora 23. I needed additional packages. So after ensuring I had the above installed, I was still having issues:
gcc: error: conftest.c: No such file or directory
gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory
From here I had to do the following:
I ensured that I wasn't lacking any C compiler tools sudo dnf group install "C Development Tools and Libraries"
Then I ran sudo dnf install redhat-rpm-config
to resolve the gcc issue listed above.
You can find a write up here on Fedore Project. You may also find answers to other needs as well.
First of all, you lack parentheses to call GetType. What you see is the MethodInfo describing the GetType method on [DayOfWeek]. To actually call GetType, you should do:
$a.GetType();
$b.GetType();
You should see that $a
is a [DayOfWeek], and $b
is a custom object generated by the Select-Object cmdlet to capture only the DayOfWeek property of a data object. Hence, it's an object with a DayOfWeek property only:
C:\> $b.DayOfWeek -eq $a
True
If you go to your android-sdk/tools
folder I think you'll find a message :
The adb tool has moved to platform-tools/
If you don't see this directory in your SDK, launch the SDK and AVD Manager (execute the android tool) and install "Android SDK Platform-tools"
Please also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.
So you should also add C:/android-sdk/platform-tools
to you environment path. Also after you modify the PATH
variable make sure that you start a new CommandPrompt
window.
Make sure you're function is wrapped in a closure, complete with the extra () at the end:
(function(){
var app = angular.module('myApp', []);
})();
With support for C++11 initializer lists it is very easy:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
using Strings = vector<string>;
void foo( Strings const& strings )
{
for( string const& s : strings ) { cout << s << endl; }
}
auto main() -> int
{
foo( Strings{ "hi", "there" } );
}
Lacking that (e.g. for Visual C++ 10.0) you can do things like this:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
typedef vector<string> Strings;
void foo( Strings const& strings )
{
for( auto it = begin( strings ); it != end( strings ); ++it )
{
cout << *it << endl;
}
}
template< class Elem >
vector<Elem>& r( vector<Elem>&& o ) { return o; }
template< class Elem, class Arg >
vector<Elem>& operator<<( vector<Elem>& v, Arg const& a )
{
v.push_back( a );
return v;
}
int main()
{
foo( r( Strings() ) << "hi" << "there" );
}
You can even use this one. worked well for me
$("#registerform").attr("action", "register.php?btnsubmit=Save")
$('#registerform').submit();
this will submit btnsubmit =Save as GET value to register.php form.
You can do one of the following:
<?php
$data = 'My data';
function menugen() {
global $data;
echo "[" . $data . "]";
}
menugen();
Or
<?php
$data = 'My data';
function menugen() {
echo "[" . $GLOBALS['data'] . "]";
}
menugen();
That being said, overuse of globals can lead to some poor code. It is usually better to pass in what you need. For example, instead of referencing a global database object you should pass in a handle to the database and act upon that. This is called dependency injection. It makes your life a lot easier when you implement automated testing (which you should).
I still use the <center> tag sometimes because nothing in CSS works as well. Examples of trying to use a <div> trick and failing:
<div style="text-align: center;">This div is centered, but it's a simple example.</div>_x000D_
<br />_x000D_
<div style="text-align: center;"><table border="1"><tr><td><div style="text-align: center;"> didn't center correctly.</td></tr></table></div>_x000D_
<br />_x000D_
<div style="text-align: center;margin-left:auto;margin-right:auto"><table border="1"><tr><td><div style="text-align: center;margin-left:auto;margin-right:auto"> still didn't center either</td></tr></table></div>_x000D_
<br />_x000D_
<center><table border="1"><tr><td>Actually Centered with <center> tag</td></tr></table></center>
_x000D_
<center> gets results. To use CSS instead, you sometimes have to put CSS in several places and mess with it to get it to center right. To answer your question, CSS has become a religion with believers and followers who shunned <center> <b> <i> <u> as blasphemy, unholy, and much too simple for the sake of their own job security. And if they try to take your <table> away from you, ask them what the CSS equivalent of the colspan or rowspan attribute is.
It is not the abstract or bookish truth, but the lived truth that counts.

Use angular.copy when assigning value of object or array to another variable and that object
value should not be changed.

See the example code and demo at the bottom of the jquery documentation page:

Is the Config/setup.php
file actually in /test/content/home/
or is in your document root? it is best to make all references relative to your document root.
include $_SERVER['DOCUMENT_ROOT'] . "Config/setup.php";
Your current code assumes that the location of setup.php
is in /text/content/home/Config/setup.php
, is this correct?
You can do exactly that via the various sizeWithFont:
methods in NSString UIKit Additions. In your case the simplest variant should suffice (since you don't have multi-line labels):
NSString *someString = @"Hello World";
UIFont *yourFont = // [UIFont ...]
CGSize stringBoundingBox = [someString sizeWithFont:yourFont];
There are several variations of this method, eg. some consider line break modes or maximum sizes.
Unlike the other answers that use a formatter, you can also just add an "0" text in front of each number inside of the loop, like this:
for myInt in 1...3 {
println("0" + "\(myInt)")
}
But formatter is often better when you have to add suppose a designated amount of 0s for each seperate number. If you only need to add one 0, though, then it's really just your pick.
You can import a bunch of .java files to your existing project without creating a new project. Here are the steps:
Check the following webpage for more information: http://people.cs.uchicago.edu/~kaharris/10200/tutorials/eclipse/Step_04.html
maybe your mysql-server didn't started
you can try

Perhaps your Apache is bounded to localhost only. Look in your apache configuration file for:
Listen 127.0.0.1:80
If you found it, replace it for:
Listen 80
Shutting down "some system process" may be tricky... you should rather edit the [Apache folder]/conf/httpd.conf as mentioned by @Sergey Maksimenko and if you want to configure virtual host, use the new port in [Apache folder]/conf/extra/httpd-vhosts.conf (I used 4900 instead of 80 and 4901 instead of 443 in [Apache folder]/conf/httpd-ssl.conf). And remember to use the port when accessing page on localhost (or your virtualhost), for example: localhost:4900/index.html
For a <br>
on each line, use
<textarea wrap="physical"></textarea>
You will get \n
s in the value of the textarea. Then, use the nl2br()
function to create <br>
s, or you can explode() it for <br>
or \n
.
Hope this helps

In case if you are not aware of the number and name of columns in dataframe then this method can be handy:
column_list = []
df_column = pd.read_excel(file_name, 'Sheet1').columns
for i in df_column:
column_list.append(i)
converter = {col: str for col in column_list}
df_actual = pd.read_excel(file_name, converters=converter)
where column_list is the list of your column names.
It's always dangerous to have NULL
in the IN
list - it often behaves as expected for the IN
but not for the NOT IN
:
IF 1 NOT IN (1, 2, 3, NULL) PRINT '1 NOT IN (1, 2, 3, NULL)'
IF 1 NOT IN (2, 3, NULL) PRINT '1 NOT IN (2, 3, NULL)'
IF 1 NOT IN (2, 3) PRINT '1 NOT IN (2, 3)' -- Prints
IF 1 IN (1, 2, 3, NULL) PRINT '1 IN (1, 2, 3, NULL)' -- Prints
IF 1 IN (2, 3, NULL) PRINT '1 IN (2, 3, NULL)'
IF 1 IN (2, 3) PRINT '1 IN (2, 3)'

I've been thinking over this and experimenting with height of the elements: html, body and div. Finally I came up with the code:
<!DOCTYPE html>_x000D_
<html>_x000D_
<head>_x000D_
<meta charset="utf-8" />_x000D_
<title>Height question</title>_x000D_
<style>_x000D_
html {height: 50%; border: solid red 3px; }_x000D_
body {height: 70vh; border: solid green 3px; padding: 12pt; }_x000D_
div {height: 90vh; border: solid blue 3px; padding: 24pt; }_x000D_
_x000D_
</style>_x000D_
</head>_x000D_
<body>_x000D_
_x000D_
<div id="container">_x000D_
<p><html> is red</p>_x000D_
<p><body> is green</p>_x000D_
<p><div> is blue</p>_x000D_
</div>_x000D_
_x000D_
</body>_x000D_
</html>
_x000D_
With my browser (Firefox 65@mint 64), all three elements are of 1) different height, 2) every one is longer, than the previous (html is 50%, body is 70vh, and div 90vh). I also checked the styles without the height with respect to the html and body tags. Worked fine, too.
