d2101 | train | What Conrad said, you need to send the file in smaller sizes, depending on what kind pf PPC you have. That could be as small as few mb, and then write to either a storage card or the main memory.
I personaly use FTP to transfer "big" files ( Ranging in the hundreds of mb ) to transfer to my PPC, but im sure you can use any other solution you may desire. But you need to research the limits of your target PPC, they often have limited memory,storage and CPU.
There is also a built in http downloader class in the .net compact framework you can use. | unknown | |
d2102 | train | Try this:
select src.id ID_wo_fresh, tgt.id ID_w_fresh, src.title
from tbl src
inner join tbl tgt on src.title= replace(replace(tgt.title,' (fresh)',''),' (Fresh)','')
and src.id <> tgt.id
This will return the ID of product without 'fresh' or 'Fresh' in the name, the ID with 'fresh' or 'Fresh' in the name and the name itself. Note that this will exclude rows which don't find a match i.e. only have the name with or without suffix, but not both. To show for all rows, use left join instead. | unknown | |

d2105 | train | Okay so to have a negative margin you can use translateX, translateY or TranslationZ.
in xml like so:
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World!"
android:translationX="-60dp"
android:translationY="-90dp"
android:translationZ="-420dp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
or programmatically like so:
View view = ...;
view.setTranslationX(-60);
view.setTranslationY(-90);
view.setTranslationZ(-420);
Then in order to slowly bring it in from right to left you can use the animate() method like so:
View view = ...;
view.animate().setDuration(1000).translationX(-600).start();
A: There is a problem with setting the width of the button using app:layout_constraintWidth_percent when the ImageView has a negative margin. The problem should go away if you can set a definite width to the button (instead of 0dp).
The problem should also resolve if you set app:layout_constraintWidth_percent to a value such that the text of the button shows completely on one line.
Here is a simplified layout to demonstrate this issue. The ConstraintLayout has two views that are simply constrained to the parent to appear in vertical center of the layout. These two views have no dependencies on each other. In addition, the ImageView has a top margin of -250dp, so it should appear above the layout's vertical center.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/holo_green_light">
<ImageView
android:id="@+id/redRectangle"
android:layout_width="100dp"
android:layout_height="30dp"
android:layout_marginTop="-250dp"
android:layout_marginEnd="16dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:srcCompat="@drawable/red_rectangle" />
<Button
android:id="@+id/button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Button"
android:textSize="18sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_default="percent"
app:layout_constraintWidth_percent="0.12" />
</androidx.constraintlayout.widget.ConstraintLayout>
Here is what happens then the width of the ImageView is changed from 0dp to a non-zero value of 1dp. When the width is set to 0dp, the negative margin seems to be ignored. It is only when the width is set to a non-zero value that the ImageView is correctly placed.
Changing the width of the button should have no effect on the placement of the ImageView; however, the button only appears in the proper position when the button has a non-zero width.
Here is what happens when the app:layout_constraintWidth_percent is increased so that the word "Button" is not cutoff.
Again, the placement of the ImageView should be independent of the width of the button. Instead, the button only appears in the correct position when the app:layout_constraintWidth_percent is set such that the word "Button" is not cutoff.
This is only an issue with negative margins. Positive margins work as expected.
This is a strange problem, so you may want to use one of the other solutions mentioned.

d2106 | train | You can disable/suppress the warnings for imports as suggested in this answer: How to disable pylint warnings and messages on Visual Studio Code?
Use --disable=reportMissingImports to disable only this kind of warnings. You can find the list of Warnings here.
This comes with the downside that VS Code won't underline other packages (e.g. pandas) if it's not installed in the environment.
A: First, you have to check whether you have selected the correct interpreter.(Ctrl+Shift+P then type Python:Select Interpreter).
When you confirm that there is no problem, but there are still errors. If you want to disable the reminder, you can add the following codes to your settings.json:
"python.analysis.diagnosticSeverityOverrides": {
"reportMissingImports": "none"

d2108 | train | What does URL look like? jQuery figures out it's a JSONP request by adding ?callback= or ?foo= to the url. Request.JSONP instead uses an option callbackKey.
There's no method option for JSONP (in any library), since it's just injecting a script tag.
var myRequest = new Request.JSONP({
url: url,
callbackKey: 'callback'
onComplete: function(data){}
}).send();
I have a feeling, however, you aren't using JSONP, but rather XHR with JSON. If that's the case, use Request.JSON, not Request.JSONP.
Edit
Since it sounds, from the comments on this answer, that you're not using JSONP, just do this:
new Request.JSON({
url: url,
method: 'get',
onSuccess: function (data){
console.log(data)
}
}).send()
Edit 2
To change the request headers just add them as an option:
new Request.JSON({
headers: {
'X-Requested-With': 'XMLHttpRequest',
'Accept': 'text/javascript, text/html, application/xml, text/xml, */*'
},
url: url,
method: 'get',
onSuccess: function (data){
console.log(data)
}
}).send()
A: You had a syntax error in your code.
var myRequest = new Request.JSONP({
url: url,
method: 'get',
onComplete: function(data){}
});
myRequest.send();
Also, the response should be wrapped with callback function, example: http://jsfiddle.net/zalun/yVbYQ/
A: Your ajax call should be like this
$.ajax({
type: "GET",
url: "http://localhost:17370/SampleService.asmx/HelloWorld",
data: "{}",
crossDomain: true,
contentType: "application/json; charset=utf-8",
dataType: "jsonp",
async:false,
success:function(data,status){
alert(data);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Error Occured!" + " | " +
XMLHttpRequest + " | " + textStatus + " | " +
errorThrown);
}
});

d2109 | train | Look at WTSSendMessage():
Displays a message box on the client desktop of a specified Remote Desktop Services session. | unknown | |
d2110 | train | It's quite simple. They allow you to write
push @hashes, { ... };
f(config => { ... });
instead of
my %hash = ( ... );
push @hashes, \%hash;
my %config = ( ... );
f(config => \%config);
(If you want to know the purpose of references, that's another story entirely.)
A: Anything "anonymous" is a data structure that used in a way where it does not get a name.
Your question has confused everyone else on this page, because your example shows you giving a name to the hash you created, thus it is no longer anonymous.
For example - if you have a subroutine and you want to return a hash, you could write this code:-
return {'hello'=>123};
since it has no name there - it is anonymous. Read on to unwind the extra confusion other people have added on this page by introducing references, which are not the same thing.
This is another anonymous hash (an empty one):
{}
This is an anonymous hash with something in it:
{'foo'=>123}
This is an anonymous (empty) array:
[]
This is an anonymous array with something in it:
['foo',123]
Most of the time when people use these things, they are really trying to magically put them inside of other data structures, without the bother of giving them a waste-of-time temporary name when they do this.
For example - you might want to have a hash in the middle of an array!
@array=(1,2,{foo=>3});
that array has 3 elements - the last element is a hash! ($array[2]->{foo} is 3)
perl -e '@array=(1,2,{foo=>1});use Data::Dumper;print Data::Dumper->Dump([\@array],["\@array"]);'
$@array = [
1,
2,
{
'foo' => 1
}
];
Sometimes you want to don't want to pass around an entire data structure, instead, you just want to use a pointer or reference to the data structure. In perl, you can do this by adding a "\" in front of a variable;
%hashcopy=%myhash; # this duplicates the hash
$myhash{test}=2; # does not affect %hashcopy
$hashpointer=\%myhash; # this gives us a different way to access the same hash
$hashpointer->{test}=2;# changes %myhash
$$hashpointer{test}=2; # identical to above (notice double $$)
If you're crazy, you can even have references to anonymous hashes:
perl -e 'print [],\[],{},\{}'
ARRAY(0x10eed48)REF(0x110b7a8)HASH(0x10eee38)REF(0x110b808)
and sometimes perl is clever enough to know you really meant reference, even when you didn't specifically say so, like my first "return" example:
perl -e 'sub tst{ return {foo=>bar}; }; $var=&tst();use Data::Dumper;print Data::Dumper->Dump([\$var],["\$var"]);'
$var = \{
'foo' => 'bar'
};
or:-
perl -e 'sub tst{ return {foo=>bar}; }; $var=&tst(); print "$$var{foo}\n$var->{foo}\n"'
bar
bar
A: It is a reference to a hash that can be stored in a scalar variable. It is exactly like a regular hash, except that the curly brackets {...} creates a reference to a hash.
Note the usage of different parentheses in these examples:
%hash = ( foo => "bar" ); # regular hash
$hash = { foo => "bar" }; # reference to anonymous (unnamed) hash
$href = \%hash; # reference to named hash %hash
This is useful to be able to do, if you for example want to pass a hash as an argument to a subroutine:
foo(\%hash, $arg1, $arg2);
sub foo {
my ($hash, @args) = @_;
...
}
And it is a way to create a multilevel hash:
my %hash = ( foo => { bar => "baz" } ); # $hash{foo}{bar} is now "baz"
A: You use an anonymous hash when you need reference to a hash and a named hash is inconvenient or unnecessary. For instance, if you wanted to pass a hash to a subroutine, you could write
my %hash = (a => 1, b => 2);
mysub(\%hash);
but if there is no need to access the hash through its name %hash you could equivalently write
mysub( {a => 1, b => 2} );
This comes in handy wherever you need a reference to a hash, and particularly when you are building nested data structures. Instead of
my %person1 = ( age => 34, position => 'captain' );
my %person2 = ( age => 28, position => 'boatswain' );
my %person3 = ( age => 18, position => 'cabin boy' );
my %crew = (
bill => \%person1,
ben => \%person2,
weed => \%person3,
);
you can write just
my %crew = (
bill => { age => 34, position => 'captain' },
ben => { age => 28, position => 'boatswain' },
weed => { age => 18, position => 'cabin boy' },
);
and to add a member,
$crew{jess} = { age => 4, position => "ship's cat" };
is a lot neater than
my %newperson = ( age => 4, position => "ship's cat" );
$crew{jess} = \%newperson;
and of course, even if a hash is created with a name, if its reference is passed elsewhere then there may be no way of using that original name, so it must be treated as anonymous. For instance in
my $crew_member = $crew{bill}
$crew_member is now effectively a reference to an anonymous hash, regardless of how the data was originally constructed. Even if the data is (in some scope) still accessible as %person1 there is no general way of knowing that, and the data can be accessed only by its reference. | unknown | |

A: Hey, if your array is sorted, u can use the Collections.binarySearch() or Arrays.binarySearch() method to guide u at what index to make the insertion.

A: There's an easier, built-in way to do this.

<ResourceDictionary>
<Path x:Shared="False" x:Key="N44" Width="20" Height="80" Stretch="Fill" Fill="#FF000000" Data="..."/>
</ResourceDictionary>
</UserControl.Resources>
A: I've since found that I had missed an important part of the documentation from MSDN:
Shareable Types and UIElement Types:
A resource dictionary is a technique for
defining shareable types and values of
these types in XAML. Not all types or
values are suitable for usage from a
ResourceDictionary. For more
information on which types are
considered shareable in Silverlight,
see Resource Dictionaries.
In particular, all UIElement derived
types are not shareable unless they
come from templates and application of
a template on a specific control
instance. Excluding the template case,
a UIElement is expected to only exist
in one place in an object tree once
instantiated, and having a UIElement
be shareable would potentially violate
this principle.
Which I will summarise as, that's not the way it works because it’s not creating a new instance each time I execute that code – it’s only creating a reference to the object – which is why it works once but not multiple times.
So after a bit more reading I’ve come up with 3 potential ways for a resolution to my problem.
1) Use a technique to create a deep copy to a new object. Example from other StackOverflow Question - Deep cloning objects
2) Store the XAML in strings within the application and then use the XAML reader to create instances of the Paths:
System.Windows.Shapes.Path newPath = (System.Windows.Shapes.Path)System.Windows.Markup.XamlReader.Parse("<Path xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' Width='20' Height='80' Stretch='Fill' Fill='#FF000000' Data='M 20,25.2941L 20,29.4118L 15.9091,29.4118L 15.9091,40L 12.2727,40L 12.2727,29.4118L 2.54313e-006,29.4118L 2.54313e-006,25.6985L 13.4872,7.62939e-006L 15.9091,7.62939e-006L 15.9091,25.2941L 20,25.2941 Z M 12.2727,25.2941L 12.2727,5.28493L 2.09517,25.2941L 12.2727,25.2941 Z M 20,65.2941L 20,69.4118L 15.9091,69.4118L 15.9091,80L 12.2727,80L 12.2727,69.4118L -5.08626e-006,69.4118L -5.08626e-006,65.6985L 13.4872,40L 15.9091,40L 15.9091,65.2941L 20,65.2941 Z M 12.2727,65.2941L 12.2727,45.2849L 2.09517,65.2941L 12.2727,65.2941 Z ' HorizontalAlignment='Left' VerticalAlignment='Top' Margin='140,60,0,0'/>");
LayoutRoot.Children.Add(newPath);
3) Only store the Path data in the Resource Dictionary. Create a new instance of a Path in code, apply the Path data to the new Path and then add the other properties I am interested in manually.
The XAML - The Path data is stored as a StreamGeometry:
<UserControl.Resources>
<ResourceDictionary>
<StreamGeometry x:Key="N44">M 20,25.2941L 20,29.4118L 15.9091,29.4118L 15.9091,40L 12.2727,40L 12.2727,29.4118L 2.54313e-006,29.4118L 2.54313e-006,25.6985L 13.4872,7.62939e-006L 15.9091,7.62939e-006L 15.9091,25.2941L 20,25.2941 Z M 12.2727,25.2941L 12.2727,5.28493L 2.09517,25.2941L 12.2727,25.2941 Z M 20,65.2941L 20,69.4118L 15.9091,69.4118L 15.9091,80L 12.2727,80L 12.2727,69.4118L -5.08626e-006,69.4118L -5.08626e-006,65.6985L 13.4872,40L 15.9091,40L 15.9091,65.2941L 20,65.2941 Z M 12.2727,65.2941L 12.2727,45.2849L 2.09517,65.2941L 12.2727,65.2941 Z</StreamGeometry>
</ResourceDictionary>
</UserControl.Resources>

d2115 | train | Do not mix db thinking with PHP code design.. Regulary the property should be set to the object itself rather then to its id. Like this:

But there are reasons when it might make sense to just have to id of the contact.

Then it might be useful to only have the id as class property and fetch the contact if required. (Known as 'lazy loading').

It looks like you're not getting past the try statement (good use of a try/except to handle Exceptions!) so the issue I think lies in the way you're indexing the items (d) in data. Think about it: if data didn't exist (meaning you didn't initialize it in your code for your program to use), how can you try to index it later on? Also, it's weird that you're not getting a NameError as I don't see data defined anywhere unless you cropped out where it was defined earlier (unless my eyes are tricking me).
General Programming principles:
*
*Iterable Objects: String, List, Dictionary, etc...
*Non-iterable Objects: Integer, Float, Boolean, etc... (depending on programming language)
Iterable data types are ones that you can index using bracket notation ([]) so in any case, you'll need to know the types of your variables and then use the correct "processes" to work with them. Since you are indexing items in data, the data type of data therefore, needs to be an iterable too.
In general, an IndexError means that you've tried to access/index an item in a list for example but that item didn't exist. Therefore, I think that trying to string AND index an item in an object that doesn't exist is giving you that error.
Here's what I think would help:
If I could see where you have data defined, I would be able to tell you where you may be going wrong, but for now, I can only recommend you going back to see whether you've indexed an item in d in data that doesn't exist.
An example (I will assume data is a list for clarity):
>>> data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
>>> data[0] # index a list in d in data
[1, 2, 3]
>>> data[0][1]
2
# If you try to access an index in data that doesn't exist:
>>> data[3]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IndexError: list index out of range
I probably over-explained by now, so I'll just end this here. The above implementation was to give you an idea of how to access a list in a list correctly and when it isn't properly done what can happen. Hope this is clear! | unknown | |
d2127 | train | Have a look at the COLLECT AQL command, it can return the count of documents that contain duplicate values, such as your id key.
ArangoDB AQL - COLLECT
You can use LET a lot in AQL to help break down a query into smaller steps, and work with the output in future queries.
It may be possible to also collapse it all into one query, but this technique helps break it down.
LET duplicates = (
FOR d IN myCollection
COLLECT id = d.id WITH COUNT INTO count
FILTER count > 1
RETURN {
id: id,
count: count
}
)
FOR d IN duplicates
FOR m IN myCollection
FILTER d.id == m.id
RETURN m
This will return:

"_id": "myCollection/416140",
"_rev": "_au4sAfS--_",

d2130 | train | You can use function annotations for Python3:
def return_locals_rpc_decorator(fun):
def decorated_fun(*args, **kw):
local_args = fun(*args, **kw)
print(local_args)
fun_parameters = fun.__annotations__
final_parameters = {a:list(args)[int(b[-1])-1] for a, b in fun_parameters.items() if a != 'return'}
return final_parameters
return decorated_fun
@return_locals_rpc_decorator
def my_funct(a:"val1", b:"val2", c:"val3") -> int:
return a + b + c
print(my_funct(10, 20, 30))
Output:
60
{'a': 10, 'b': 20, 'c': 30}
In this way, you are using the wrapper function decorated_fun to access the decorated function's parameters and further information specified by the annotation. I changed the parameter descriptions in the annotations so that each string value would end in a digit that could be used to index args. However, if you do not want to change the parameter descriptions in the annotations, you can sort via ending character.
Edit: the code in the body of my_funct is executed when called in the wrapper function (decorated_fun), since the args, declared in the scope of decorated_fun is passed to and unpacked in local_args. | unknown | |
d2131 | train | ns = []
while not ns or ns[-1] != -9999:
ns.append(int(input("Please, enter number {}(-9999 to end"))))
A: ns = list(iter(lambda:int(input("Enter Number:")),-9999))
is a cool way to do it
iter can take a sentinal value to wait for as a second argument, if you use a function for the first argument
as an aside with your positive and negatives .... it seems it will ignore zeros (which may be intentional)...
A: This code will loop while you add numbers to your list and stop when you enter -9999. It will then throw the -9999 away so you can get on with your averaging. It's not compact, but it works and it's simple.
numbers = []

d2132 | train | When you write an image that contains one or more partitions, you also write the partition table, which is expected to be at some offset or your memory by u-boot (according to this post it must be 0x60000000). So if you write your image again somewhere else, u-boot will still refer to the partition table from your first writing operation, which itself contains the memory address of your first 4 partitions. Your second partition table is somewhere else on the disk, but u-boot doesn't know.
You can try to repair the partition table using the testdisk command line utility. It will scan the whole disk and hopefully it will find that there is 8 partitions in total, and create a new partition table at 0x60000000 that refers to all of them. | unknown | |

Or, probably even simpler, something like this:

d2134 | train | Re-query with same filters as in 1 in Z Thread.
Return results in Main Thread.
Okay so this is completely unnecessary because you can create a RealmQuery and store a field reference to the RealmResults, add a RealmChangeListener to it, and when you insert into Realm on the background thread, it will automatically update the RealmResults and call the RealmChangeListener.
So you don't need to "re-query with same filters in Z thread" (because Realm's findAllSortedAsync() already queries on a background thread), and you don't need to manually return results in main thread because findAllSortedAsync() already does that.
Solution: use Realm's notification system (and async query API). Read the docs: https://realm.io/docs/java/latest/#notifications | unknown | |

select v.*, case when w.lot# is null then 0 else 1 end flag
from vehicle v
left join whishlist w on w.userid = @user and w.lot# = v.lot_
You can easily integrate this query in your stored procedure and add the row-limiting clause.
A: I recommend using EXISTS:
SELECT v.*,
(CASE WHEN EXISTS (SELECT 1
FROM wishlist wl
WHERE v.lot# = wl.lot_ AND
wl.userid = @user
)
THEN 1 ELSE 0
END) as Flag
FROM vehicle1 v

FETCH NEXT 10 ROWS ONLY;
I think it better captures the logic that you want. I also suspect that it might work better with ORDER BY and FETCH. | unknown | |
d2137 | train | You can use Awk, provided you force the use of the C locale:
LC_CTYPE=C awk '! /[^[:alnum:][:space:][:punct:]]/' my_file
The environment variable LC_TYPE=C (or LC_ALL=C) force the use of the C locale for character classification. It changes the meaning of the character classes ([:alnum:], [:space:], etc.) to match only ASCII characters.
The /[^[:alnum:][:space:][:punct:]]/ regex match lines with any non ASCII character. The ! before the regex invert the condition. So only lines without any non ASCII characters will match. Then as no action is given, the default action is used for matching lines (print).
EDIT: This can also be done with grep:
LC_CTYPE=C grep -v '[^[:alnum:][:space:][:punct:]]' my_file
A: With GNU grep, which supports perl compatible regular expressions, you can use:
grep -P '^[[:ascii:]]+$' file
A: You can use egrep -v to return only lines not matching the pattern and use something like [^ a-zA-Z0-9.,;:-'"?!] as pattern (include more punctuation as needed).
Hm, thinking about it, a double negation (-v and the inverted character class) is probably not that good. Another way might be ^[ a-zA-Z0-9.,;:-'"?!]*$.
You can also just filter for ASCII:
egrep -v "[^ -~]" foo.txt

d2140 | train | You can use the CursorMoved and CursorMovedI autocommands to set the desired textwidth (or any other setting) based on the line the cursor is currently on:
augroup gitsetup
autocmd!
" Only set these commands up for git commits
autocmd FileType gitcommit
\ autocmd CursorMoved,CursorMovedI *
\ let &l:textwidth = line('.') == 1 ? 50 : 72
augroup end
The basic logic is simple: let &l:textwidth = line('.') == 1 ? 50 : 72, although the nested autocommands make it look rather funky. You could extract some of it out to a script-local function (fun! s:setup_git()) and call that, if you prefer.
The &:l syntax is the same as setlocal, by the way (but with setlocal we can't use an expression such as on the right-hand-side, only a simple string).
Some related questions:
*
*Line number specific text-width setting.
*Set paste mode when at beginning of line but auto-indent mode when anywhere else on the line?
Note that the default gitcommit.vim syntax file already stops highlighting the first line after 50 characters. From /usr/share/vim/vim80/syntax/gitcommit.vim:
syn match gitcommitSummary "^.\{0,50\}" contained containedin=gitcommitFirstLine nextgroup=gitcommitOverflow contains=@Spell
[..]
hi def link gitcommitSummary Keyword
Only the first 50 lines get highlighted as a "Keyword" (light brown in my colour scheme), after that no highlighting is applied.
If also has:
syn match gitcommitOverflow ".*" contained contains=@Spell
[..]
"hi def link gitcommitOverflow Error
Notice how it's commented out, probably because it's a bit too opinionated. You can easily add this to your vimrc though:
augroup gitsetup
autocmd!
" Only set these commands up for git commits
autocmd FileType gitcommit
\ hi def link gitcommitOverflow Error
\| autocmd CursorMoved,CursorMovedI *
\ let &l:textwidth = line('.') == 1 ? 50 : 72
augroup end
Which will make everything after 50 characters show up as an error (you could, if you want, also use less obtrusive colours by choosing a different highlight group). | unknown | |

if course_a == course_b:
# Do something
When comparing two lists, you call list.__eq__ method instead. If this list contains your Courses objects (btw, you should use singular form, as it is single Course), they will be compared using your defined __eq__ method.
This means, that you can just compare [course_a, course_b] == [course_a, course_c] and it should work as you intented.

d2152 | train | You're problem is that you are doing this on the wrong end of things -- you should be filtering all user input of potentially hostile content when you receive it.
The first rule of thumb when doing this is "always whitelist, never blacklist". Rather than allowing any and all attributes in your user-generated HTML, simply keep a list of allowed attributes and strip away all others when you receive the HTML (possibly on the client side -- definitely on the server side.)
Oh, and HTML is not a regular language. You'll want to use an HTML parser, not a regular expression for this task.
A: .unbind will only unbind events attached using jQuery. You can get rid of inline event handler code by setting them to null, e.g.:
$("preventjs *").removeAttr("onclick").removeAttr("onmouseover");
Demo.
EDIT: Here's an evil solution, you can remove all attributes starting with "on":
$("preventjs *").each(function() {
var attribs = this.attributes;
var that = this;
$.each(attribs, function(i, attrib) {
if(attrib.name.indexOf("on") === 0) {
$(that).removeAttr(attrib.name);
}
});
});
Demo.
A: The problem is that you've inline handlers. unbind cannot remove inline handlers.
<p onclick="alert('evil stuff'...
^^^^
To remove inline handlers, use removeAttr
$("preventjs").find("*").removeAttr('onclick');
$("preventjs").find("*").removeAttr('onmouseover');
A: You can unbind the events individually:
$('p').each(function(){ this.onclick = this.onmouseover = undefined; });
If you want to unbind other events like mouseout you have to add them to that list:
$('p').each(function(){ this.onclick =
this.onmouseover =
this.onmouseout = undefined; });
Of course you'll want to use a selector other than $('p'), I just didn't want to put your other one because preventjs is not an HTML tag | unknown | |

Add a destructor to the Contained class:

This will ensure whenever your contained object goes out of scope, it will automatically delete the data pointer it has. So if you do
//delete first element
rooms.erase(rooms.begin());
data ptr of that object will automatically be deleted.
Using smart pointers
Use std::unique_ptr<T>.
class Contained {

Using smart pointers i.e., (unique_ptr, shared_ptr) ensures your pointer will automatically delete when no one is owning it. Since you can not copy unique_ptr but only move it, you should define a move constructor and move assignment operator on the Contained class.
Contained::Contained(Contained&& other)

d2156 | train | There is probably no good reason to have a method accepting only GString as input or output. GString is meant to be used interchangeably as a regular String, but with embedded values which are evaluated lazily.
Consider redefining the method as:
void foo (String baa)
void foo (CharSequence baa) //more flexible
This way the method accepts both String and GString (GString parameter is automagically converted to String as needed). The second version even accepts StringBuffer/Builder/etc.
If you absolutely need to keep the GString signature (because it's a third party API, etc.), consider creating a wrapper method which accepts String and does the conversion internally. Something like this:
void fooWrapper (String baa) {
foo(baa + "${''}")
}
A: You can create overloaded methods or you can use generics; something as below:
foo("Hello from foo GString ${X}")
foo("Hello from foo")
MyClass.foo("Hello from foo GString ${X}")
MyClass.foo("Hello from foo")
// method with GString as parameter
void foo(GString g) {

// overloading method with String as parameter

d2157 | train | You need to re-write all of the members/methods in the interface and add the abstract keyword to them, so in your case:
interface baseInter {
name: string;
test();
}
abstract class abs implements baseInter {
abstract name: string;
abstract test();
}
(code in playground)
There was a suggestion for it: Missing property declaration in abstract class implementing interfaces but it was declined for this reason:
Although, the convenience of not writing the declaration would be
nice, the possible confusion/complexity arising from this change would
not warrant it. by examine the declaration, it is not clear which
members appear on the type, is it all properties, methods, or
properties with call signatures; would they be considered abstract?
optional?
A: You can get what you want with a slight trick that defeats the compile-time errors:
interface baseInter {
name : string;
test();
}
interface abs extends baseInter {}
abstract class abs implements baseInter{
}
This trick takes advantage of Typescript's Declaration Merging, and was originally presented here and posted on a related SO question here.
A: Interfaces are used for defining a contract regarding the shape of an object.
Use constructor to pass in properties to the class
interface BaseInter {
name : string;
test(): boolean;
}
abstract class Abs implements BaseInter {
constructor(public name: string) {}
test(): boolean {

Which means a sublist starts with 'z' and must end with 'x', yes? In that case the itertools.groupby solution I posted will not work exactly. The way it's written now it will generate a new sublist that starts and ends with either 'z' or 'x'. Let me know if this really matters or not.
A: st.replace("z", "[").replace("x", "]") | unknown | |
d2159 | train | In your controller add pagination library, logic create offset & limit, and load view of listing like wise... (Place normal pagination code here)
Write this jquery code on your view to load different pages :
<script>
$(function(){
$("#pagination-div-id a").click(function(){
$.ajax({
type: "POST",
url: $(this).attr("href"),
data:"q=<?php echo $searchString; ?>",
success: function(res){
$("#containerid").html(res);
}
});
return false;
});

d2161 | train | You should try using Application Gateway V2, its a lot faster to create. updates are almost instantaneous (well, at least compared to V1). But I believe V1 is using windows VM's underneath, so it creates a set of vms for you, then it configures them. Each update would be a "sliding window" update, with 1 vm being recreated at a time.
As far as I know.
A: Application Gateway is a layer 7 load balancer which, as far as I understand, is a Windows VM (or collection of Windows VMs, depending on selected size) under the covers, which take some time to come up and be configured. In my experience, this time is usually around 15-30 minutes, depending on region and local time of day, capacity, etc.
Azure Load balancers on the other hand are layer 4 load balancers, which typically take in the order of 1-2 minutes to come up.
A: So, yes talking about the load balancer if you say it normally takes less than a minute to get deployed. But coming onto the Application gateway yeah it takes 15-20 minutes every time the reason being:
*
*Configuration Settings: Microsoft has the set of the vacant load balancers ready at their backend and when they receive a request to deploy a particular load balancer in any region, they just assign it an IP as requested by the user and it gets deployed within a minute. But coming onto the Application gateway, azure need to start deploying the load balancer [App Gateway in this case] from the scratch, need to attach it to the VNET so deployed and making it ready for the backend pools IP Address configuration and all, which basically take time about [15-20 minutes]. Now, Azure has brought up the V2 of the Application Gateway, a lot faster to create usually 5 minutes. And also talking about updates they are also really quick and instantaneous.
*Subscriptions: Secondly, the reason that it takes time is subscription. Suppose, you have the MSDN, free subscription in your Azure account. And another individual sitting at any different place is using the enterprise applications subscription [basically a pay as you go] in his azure account. Now, both of you raise a request to deploy an Application gateway in the same region at the same time then, Microsoft will give the person request with the enterprise subscription the higher priority than your free subscription request. Which is another reason that it results in a delay. As I am using the enterprise edition so it takes 2 minutes for a VM to deploy which gets deployed in 5-6 minutes if using the free subscription!

A: -(void) ViewDidLoad {
[super ViewDidLoad];
parser = [Parser alloc] init];
You Reallocated and reinitialised parser, is there any part of the code that you are reloading data? If not your data store will be empty.
A: My suggestions:
*
*Please check, if your tableView's delegate and dataSource are set up correctly. I haven't seen that in your code.
*Please check, what cell class is registered to your table view. I mean, you need to use tableView's registerClass:forCellReuseIdentifier: or registerNib:forCellReuseIdentifier: somewhere.
Anyway, I'm used to work with GUI without IB or storyboards (so, I'm doing everything programmatically), so it's possible that you don't need to do that.
Good luck.
A: I have similar issue before. the cause of my problem is that my view controller get released after I scroll my table view, can you please check if you have same cause?
A: Try to do the below:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString * MyIdentifier = @"ArticleCell";
ArticleCell *cell = [tableView dequeueReusableCellWithIdentifier: MyIdentifier];
Article *article = [parser items][indexPath.row];
cell.title.text = article.title;
cell.date.text = article.date;
return cell;
}
A: The problem is that the identifier used should be static string
So declare an identifier which is statisc and assign it
static NSString *cellId = @"cellIdentifier";
ArticleCell *cell = [tableView dequeueReusableCellWithIdentifier: cellId];
Also make sure the storyboard cell has the same identifier value.ie here 'cellIdentifier'
A: Check what happens with [[parser items] count] when you scroll. My guess is that it decreases which decrease the row count in your table.
I may be wrong here because I don't know what's Parser (probably your custom class?) but in case if it is used to parse HTTP response, perhaps item count decreases when the parsing has been done?
To check parser item count, add the following to your tableView:cellForRowAtIndexPath:
NSLog(@"Parser item count: %d", parser.items.count); | unknown | |
d2164 | train | It's a bug in the Blink & Webkit implementations. From the spec: "audioprocess events are only dispatched if the ScriptProcessorNode has at least one input or one output connected." It doesn't need both.

d2166 | train | As for best practices, "avoid triggers like the plague" is the best advice I could give you.
What I've done in a similar situation is to add a column that indicates that a row is now archived. I used a datetime column called ArchivedDt. Normal queries exclude this column like:

d2167 | train | Windows stores list of all fonts in registry: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts".

d2168 | train | Store the value from first selectmenu, then look for it in the second one. Select it using
.prop('selected', true); and then call .selectmenu('refresh').
Demo

$(document).on('change', '#ddl1', function () {
var selected = $(this).val();
$('#ddl2 option[value="' + selected + '"]').prop('selected', true);
$('#ddl2').selectmenu('refresh');
});
});
I used pageinit which is equivalent to .ready(). It is a special event for jQM.
A: Have you checked that the change function is actually being called. Is the script you provide the entire contents of the script tag?
The function will not be bound to the event until it is loaded, using the $(document).ready(); will bind the event to the control.
$(document).ready(function() {

d2169 | train | You are getting two errors of
You must bind Parsley on an existing element.
but those errors are not related to the code you posted.
In your ...js/site.js you have the following code:
$(document).ready(function() {
$('.slider').flexslider({controlNav: false,slideshowSpeed: 3000,directionNav: true});
$('input').iCheck({checkboxClass: 'icheckbox_square-yellow',radioClass: 'iradio_square-yellow',increaseArea: '20%'});
$('#newsletter_signup').parsley();
$('#request_a_quote').parsley();
$('#contact').parsley();
var form = $('#newsletter_signup');
(...)
You are binding parsley to three elements with the following ids: newsletter_signup, request_a_quote and contact.
The thing is, in the current page you only have the element newsletter_signup. If you do a console.log($('#request_a_quote')) you will see an empty object.
So, to fix your issue, you need to remove the code that binds parsley to non-existent elements. Or you could change your code in order to bind parsley only if the element exist. Something like this:
$(document).ready(function() {
$('.slider').flexslider({controlNav: false,slideshowSpeed: 3000,directionNav: true});
$('input').iCheck({checkboxClass: 'icheckbox_square-yellow',radioClass: 'iradio_square-yellow',increaseArea: '20%'});

extraction results in the value too large or too small to fit in
value, std::numeric_limits::max() or std::numeric_limits::min()

FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_ERROR, "Senha não informada!","Preencha a senha e tente novamente!"));
return null;
}
this is what you have to add return null; so that it will stay in the same page and show up the message, As you are trying to navigate to the login page once agin after getting the error also, it will simply navigate rather than showing error messages.
as well try to modify in the xhtml as suggested below:
and in your xhtml:
<p:growl id="growlLoginValidationStatus" showDetail="true" sticky="false" autoUpdate="true" life="4000" redisplay="false" showSummary="true" globalOnly="false" />
and remove your <p:message/> tag and make ajax as false in your command button.
try this, if still not able to show the message, let me know in comment

<h:form id="login" >
<p:commandButton value="Login" update="loginForm"

d2181 | train | From Mule-3.6 on wards, we have HTTP Listener Connector, using which you can pass URI parameters.
You can access the URI parameters using the below MEL
#[message.inboundProperties.'http.uri.params'.id] provided your URI should be like this: http://localhost:8086/idnum/{id}
A: You need to put the id as a message inbound parameter as following .. In Mule flow you need to do the following :-
<flow name="test">
<http:inbound-endpoint exchange-pattern="request-response"
host="localhost" port="8086"
path="idnum" doc:name="HTTP"/>
<!-- storing id in variable myId -->
<set-variable variableName="myId"
value="#[message.inboundProperties['id']]"
doc:name="Variable"/>
<!-- Print the variable in console -->
<logger level="INFO" message="My id :- #[flowVars['myId']]"/>
</flow>
Now in browser access
http://localhost:8086/idnum/?id=4583948364094
Now you can store it in a variable in Mule and you can see it in a logger like:
My id :- 4583948364094 | unknown | |

Do this:

A: Instead of replacing the current form, append the new lines generated by your PHP script. So you need to use $('#contact_form_div').append(data); instead of $('#contact_form_div').html(data);.
After you change that, you can use the num parameter to specify the number of rows to be added.
A: Don't ask for the whole form on every request. Keep the page you have now to do the first load of the form when you load the page.
Then, make a php page that outputs a single row of results, request it via ajax as you have done, then append the result to the current html of the page.
A: replace this:
$('#contact_form_div').html(data);
with this :
$('#contact_form_div').append(data);

d2188 | train | I actually ran into a very similar issue last night when I was working with a Xamarin.Forms application in Xamarin Studio. I had recently updated the Xamarin.Forms and Xamarin.Android.Support.v4 packages in my Android project when it started happening. I believe what I did to get it to work again (I tried a number of things so I'm not exactly sure which one actually fixed it) was to go into my Android project and delete the references to both Xamarin.Forms and Xamarin.Android.Supoort.v4. Then I went into "Manage NuGet Packages" and I added the official Xamarin.Forms library. Since the Xamarin.Android.Support.v4 package is a dependency it pulled that down for me as well.

d2190 | train | For the A problem, you could count the number of white pixels in each column and each row. The columns/rows with the highest number of white pixels are where the borders of your rectangle are. (Assuming that the rectangle sides are parallel to the sides of the image)
For B and C the hint is to start with
Bitmap aImage; // Initialize with your images
using (Graphics g = Graphics.FromImage(aImage))
{
// Do stuff
}
And then you can find and overload of Graphics.DrawImage to scale and draw your images atop of each other.
To count the number of pixels you can use the GetPixel method.
// Sketchy code
// Calculate each column in sum[x]
[x,y] = b.Size;
for(x ...)
for(y ..)
if (aImage.GetPixel(x, y) == Color.White)
sum[x]++;
A: Here is a snippet on draing an image over another image. (No credit i took it from here)
Bitmap bmp = Bitmap.FromFile(initialFileName);
// This draws another image as an overlay on top of bmp in memory.
// There are additional forms of DrawImage; there are ways to fully specify the
// source and destination rectangles. Here, we just draw the overlay at position (0,0).
using (Graphics g = Graphics.FromImage(bmp))
{
g.DrawImage(Bitmap.FromFile(overlayFileName), 0, 0);
}
bmp.Save(saveAsFileName, System.Drawing.Imaging.ImageFormat.Png);

d2191 | train | For the newer versions of React Native you have to import Bundle and place your own onCreate Method like this:
// Added Bundle to use onCreate which is needed for our Fabrics workaround
import android.os.Bundle;
..........
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Fabrics
Fabric.with(this, new Crashlytics());
}
Not sure if this is good or not since they have removed the onCreate but it works for me
A: I got it working in some way, but it may not be the perfect solution...
1: Add fabric/crashlytics into your app/build.gradle - File
(I didn´t have the buildscript in my app/build.gradle so i just included it. But i am not sure if this is good....)
buildscript {
repositories {
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
// The Fabric Gradle plugin uses an open ended version to react
// quickly to Android tooling updates
classpath 'io.fabric.tools:gradle:1.+'
}
}
// Add this directly under: apply plugin: "com.android.application"
apply plugin: 'io.fabric'
// and this directly under: apply from: "react.gradle"
repositories {
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
// Last but not least add Crashlytics Kit into dependencies
compile('com.crashlytics.sdk.android:crashlytics:2.5.5@aar') {
transitive = true
}
2: The most important, because it is nowhere mentioned (or i didn´t find it anywhere), import Crashlytics and Fabric into MainActivity:
import com.crashlytics.android.Crashlytics;
import io.fabric.sdk.android.Fabric;
3: In your onCreate - method add:
// Fabrics
Fabric.with(this, new Crashlytics());
When you´ve done this, you will at least get Crashreports which are caused by native Code (Java Code). Crashes which are caused through JS - Syntax or similar wont be notified. There you will get the known RedBox :P
Good luck!
A: Try this : https://fabric.io/kits/android/crashlytics/install

If so, you can either replace the new line character in item2 or try to substring the content.
A: To remove any unwanted characters from the input strings, you can trim them, or do a character replacement. For example, to remove CR/LF from the end of strings (untested, from memory);
numb = numbtxt.Text.TrimEnd( {vbCr, vbLf, vbCrLf, Environment.Newline} )
or to remove all occurrences;
year = yeartxt.Text.Replace(vbCrLf, String.Empty)

d2196 | train | The name of the parameter jdbcTemplateOne has no bearing on the injection. So both parameters are asking for the same thing. There are multiple templates thus Micronaut doesn't know which one to inject.
In your factory you can create a template for each datasource with
@EachBean(DataSource.class)
JdbcTemplate jdbcTemplateOne(DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
Then the named qualifier of the datasource will transfer to the template. That means in your example you could inject @Named("database2") JdbcTemplate jdbcTemplate.
Alternatively you can add @Named qualifiers to the factory methods and then inject the jdbc templates with those qualifiers.
A: Change your repository constructor like below
@Inject
public CodeSetRepository(@Named("database2") JdbcTemplate jdbcTemplateOne) {
this.jdbcTemplateOne = jdbcTemplateOne;

d2197 | train | You can order the group before selecting the first record:
var qryLatestInterview = from rows in dt.AsEnumerable()
group rows by new
{
PositionID = rows["msbf_acc_cd"],
CandidateID = rows["msbf_fac_tp"],
} into grp
select grp.OrderBy(x=> x["msbf_fac_dt"]).First();
A: If I understand correctly, you want to get recent facilitated record from this list, you could do ordering after grouping and take first record.
dt.AsEnumerable()
.GroupBy(row => new
{
PositionID = rows["msbf_acc_cd"],
CandidateID = rows["msbf_fac_tp"]
})
.Select(x=>x.OrderByDescending(o=>o["msbf_fac_dt"]>).FirstOrDefault()
.ToList(); | unknown | |
d2198 | train | Assuming the plans are stored in a table named plan_table in a column named execution_plan you can use the following:
select replace(substring(execution_plan from '\(cost=[0-9]+'), '(cost=', '')
from plan_table;
The substring(...) returns the first occurrence of (cost= and the replace is then used to remove that prefix.
A: I get successful and the solution, the obcjetive was get the value 27726324.41, the Expression Regular final developted is:
select substring('Aggregate (cost=27726324.40..27726324.41 Rows' from '[.]Y*([0-9]+.?[0-9]{2})')
RESULT 27726324.41

d2199 | train | I believe your goal is as follows.
*
*From I want the user to click the button "Open in Google Sheet" and open the CSV as a spreadsheet., you want to retrieve the text value from the textarea tab and create a Google Spreadsheet using the text value, and then, want to open the Google Spreadsheet.
In order to achieve your goal, how about the following flow?
*
*Retrieve the text value from the textarea tab.
*Send the text value to Web Apps created by Google Apps Script.
*At Web Apps, a new Google Spreadsheet is created and the text value is put to the sheet.
*In order to open the created Spreadsheet, change the permission of the Spreadsheet. In this case, it is publicly shared as the read-only. This is the sample situation.
*Return the URL of the Spreadsheet.
When this flow is reflected in the script, it becomes as follows.
Usage:
1. Create a new project of Google Apps Script.
Sample script of Web Apps is a Google Apps Script. So please create a project of Google Apps Script.
If you want to directly create it, please access https://script.new/. In this case, if you are not logged in to Google, the log-in screen is opened. So please log in to Google. By this, the script editor of Google Apps Script is opened.
2. Sample script.
Please copy and paste the following script to the created Google Apps Script project and save it. This script is used for Web Apps. In this sample, the value is sent as the POST request.
function doPost(e) {
const csv = Utilities.parseCsv(e.postData.contents);
const ss = SpreadsheetApp.create("sample");
ss.getSheets()[0].getRange(1, 1, csv.length, csv[0].length).setValues(csv);
DriveApp.getFileById(ss.getId()).setSharing(DriveApp.Access.ANYONE_WITH_LINK, DriveApp.Permission.VIEW);
return ContentService.createTextOutput(ss.getUrl());
}
3. Deploy Web Apps.
The detailed information can be seen at the official document.
*
*On the script editor, at the top right of the script editor, please click "click Deploy" -> "New deployment".
*Please click "Select type" -> "Web App".
*Please input the information about the Web App in the fields under "Deployment configuration".
*Please select "Me" for "Execute as".
*
*This is the importance of this workaround.
*Please select "Anyone" for "Who has access".
*
*In this case, the user is not required to use the access token. So please use this as a test case.
*Of course, you can also access to your Web Apps using the access token. Please check this report.
*Please click "Deploy" button.
*Copy the URL of the Web App. It's like https://script.google.com/macros/s/###/exec.
*
*When you modified the Google Apps Script, please modify the deployment as a new version. By this, the modified script is reflected in Web Apps. Please be careful this.
*You can see the detail of this in the report of "Redeploying Web Apps without Changing URL of Web Apps for new IDE".
4. Testing.
As the test of this Web Apps, I modified your script as follows. Before you use this script, please set the URL of your Web Apps to url. When you open this HTML and click the button, a new Spreadsheet including the text value in the textarea tab is opened with new window as the read-only.
<textarea id="sampletext" value="f">id,value
2,alpha
3,beta
14,test</textarea>
<button onclick="sample()">Open in Google Sheet</button>
<script>
function sample() {
const url = "https://script.google.com/macros/s/###/exec"; // Please set the URL of your Web Apps.
fetch(url, { method: "POST", body: document.getElementById("sampletext").value })
.then((res) => res.text())
.then((url) => window.open(url, "_blank"));
}
</script>
Note:
*
*When you modified the Google Apps Script, please modify the deployment as a new version. By this, the modified script is reflected in Web Apps. Please be careful this.
*You can see the detail of this in the report of "Redeploying Web Apps without Changing URL of Web Apps for new IDE".
*My proposed script is a simple script. So please modify it for your actual situation.

d2200 | train | You can do the same with the PHP cURL extension. You just need to set the options through curl_setopt, so you would do something like this
$url = "http://www.google.com/trends/topcharts/trendingchart";
$fields = "ajax=1&cid=actors&geo=US&date=201310";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
Now you have the response of the website in $data and you can do whatever you want with it.
You can find the PHP cURL documentation on http://php.net/curl
A: Try this
// Complete url with paramters
$url = "http://www.google.com/trends/topcharts/trendingchart?ajax=1&cid=actors&geo=US&date=201310";
// Init session
$ch = curl_init();
// Set options
curl_setopt($ch, CURLOPT_URL, $url);
// Set option to return the result instead of echoing it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Execute session
$data = curl_exec($ch);
// Close session
curl_close($ch);
// Dump json decoded result
var_dump(json_decode($data, true)); | unknown |
