import re
htmlString = '</dd><dt> Fine, thank you. </dt><dd> Molt bé, gràcies. (<i>mohl behh, GRAH-syuhs</i>)'
SearchStr = '(\<\/dd\>\<dt\>)+ ([\w+\,\.\s]+)([\&\#\d\;]+)(\<\/dt\>\<dd\>)+ ([\w\,\s\w\s\w\?\!\.]+) (\(\<i\>)([\w\s\,\-]+)(\<\/i\>\))'
Result = re.search(SearchStr.decode('utf-8'), htmlString.decode('utf-8'), re.I | re.U)
print Result.groups()
Works that way. The expression contains non-latin characters, so it usually fails. You've got to decode into Unicode and use re.U (Unicode) flag.
I'm a beginner too and I faced that issue a couple of times myself.
Additional to Vasil's answer: If you have the values given as a Scala collection, you can write
val list = List(1,2,3,4,5)
val arr = Array[Int](list:_*)
println(arr.mkString)
But usually the toArray method is more handy:
val list = List(1,2,3,4,5)
val arr = list.toArray
println(arr.mkString)

echo $search_array[20120504];

An array type is denoted as T[n]
where T
is the element type and n
is a positive size, the number of elements in the array. The array type is a product type of the element type and the size. If one or both of those ingredients differ, you get a distinct type:
#include <type_traits>
static_assert(!std::is_same<int[8], float[8]>::value, "distinct element type");
static_assert(!std::is_same<int[8], int[9]>::value, "distinct size");
Note that the size is part of the type, that is, array types of different size are incompatible types that have absolutely nothing to do with each other. sizeof(T[n])
is equivalent to n * sizeof(T)
.
The only "connection" between T[n]
and T[m]
is that both types can implicitly be converted to T*
, and the result of this conversion is a pointer to the first element of the array. That is, anywhere a T*
is required, you can provide a T[n]
, and the compiler will silently provide that pointer:
+---+---+---+---+---+---+---+---+
the_actual_array: | | | | | | | | | int[8]
+---+---+---+---+---+---+---+---+
^
|
|
|
| pointer_to_the_first_element int*
This conversion is known as "array-to-pointer decay", and it is a major source of confusion. The size of the array is lost in this process, since it is no longer part of the type (T*
). Pro: Forgetting the size of an array on the type level allows a pointer to point to the first element of an array of any size. Con: Given a pointer to the first (or any other) element of an array, there is no way to detect how large that array is or where exactly the pointer points to relative to the bounds of the array. Pointers are extremely stupid.
The compiler will silently generate a pointer to the first element of an array whenever it is deemed useful, that is, whenever an operation would fail on an array but succeed on a pointer. This conversion from array to pointer is trivial, since the resulting pointer value is simply the address of the array. Note that the pointer is not stored as part of the array itself (or anywhere else in memory). An array is not a pointer.
static_assert(!std::is_same<int[8], int*>::value, "an array is not a pointer");
One important context in which an array does not decay into a pointer to its first element is when the &
operator is applied to it. In that case, the &
operator yields a pointer to the entire array, not just a pointer to its first element. Although in that case the values (the addresses) are the same, a pointer to the first element of an array and a pointer to the entire array are completely distinct types:
static_assert(!std::is_same<int*, int(*)[8]>::value, "distinct element type");
The following ASCII art explains this distinction:
+-----------------------------------+
| +---+---+---+---+---+---+---+---+ |
+---> | | | | | | | | | | | int[8]
| | +---+---+---+---+---+---+---+---+ |
| +---^-------------------------------+
| |
| |
| |
| | pointer_to_the_first_element int*
|
| pointer_to_the_entire_array int(*)[8]
Note how the pointer to the first element only points to a single integer (depicted as a small box), whereas the pointer to the entire array points to an array of 8 integers (depicted as a large box).
The same situation arises in classes and is maybe more obvious. A pointer to an object and a pointer to its first data member have the same value (the same address), yet they are completely distinct types.
If you are unfamiliar with the C declarator syntax, the parenthesis in the type int(*)[8]
are essential:
int(*)[8]
is a pointer to an array of 8 integers.int*[8]
is an array of 8 pointers, each element of type int*
.C++ provides two syntactic variations to access individual elements of an array. Neither of them is superior to the other, and you should familiarize yourself with both.
Given a pointer p
to the first element of an array, the expression p+i
yields a pointer to the i-th element of the array. By dereferencing that pointer afterwards, one can access individual elements:
std::cout << *(x+3) << ", " << *(x+7) << std::endl;
If x
denotes an array, then array-to-pointer decay will kick in, because adding an array and an integer is meaningless (there is no plus operation on arrays), but adding a pointer and an integer makes sense:
+---+---+---+---+---+---+---+---+
x: | | | | | | | | | int[8]
+---+---+---+---+---+---+---+---+
^ ^ ^
| | |
| | |
| | |
x+0 | x+3 | x+7 | int*
(Note that the implicitly generated pointer has no name, so I wrote x+0
in order to identify it.)
If, on the other hand, x
denotes a pointer to the first (or any other) element of an array, then array-to-pointer decay is not necessary, because the pointer on which i
is going to be added already exists:
+---+---+---+---+---+---+---+---+
| | | | | | | | | int[8]
+---+---+---+---+---+---+---+---+
^ ^ ^
| | |
| | |
+-|-+ | |
x: | | | x+3 | x+7 | int*
+---+
Note that in the depicted case, x
is a pointer variable (discernible by the small box next to x
), but it could just as well be the result of a function returning a pointer (or any other expression of type T*
).
Since the syntax *(x+i)
is a bit clumsy, C++ provides the alternative syntax x[i]
:
std::cout << x[3] << ", " << x[7] << std::endl;
Due to the fact that addition is commutative, the following code does exactly the same:
std::cout << 3[x] << ", " << 7[x] << std::endl;
The definition of the indexing operator leads to the following interesting equivalence:
&x[i] == &*(x+i) == x+i
However, &x[0]
is generally not equivalent to x
. The former is a pointer, the latter an array. Only when the context triggers array-to-pointer decay can x
and &x[0]
be used interchangeably. For example:
T* p = &array[0]; // rewritten as &*(array+0), decay happens due to the addition
T* q = array; // decay happens due to the assignment
On the first line, the compiler detects an assignment from a pointer to a pointer, which trivially succeeds. On the second line, it detects an assignment from an array to a pointer. Since this is meaningless (but pointer to pointer assignment makes sense), array-to-pointer decay kicks in as usual.
An array of type T[n]
has n
elements, indexed from 0
to n-1
; there is no element n
. And yet, to support half-open ranges (where the beginning is inclusive and the end is exclusive), C++ allows the computation of a pointer to the (non-existent) n-th element, but it is illegal to dereference that pointer:
+---+---+---+---+---+---+---+---+....
x: | | | | | | | | | . int[8]
+---+---+---+---+---+---+---+---+....
^ ^
| |
| |
| |
x+0 | x+8 | int*
For example, if you want to sort an array, both of the following would work equally well:
std::sort(x + 0, x + n);
std::sort(&x[0], &x[0] + n);
Note that it is illegal to provide &x[n]
as the second argument since this is equivalent to &*(x+n)
, and the sub-expression *(x+n)
technically invokes undefined behavior in C++ (but not in C99).
Also note that you could simply provide x
as the first argument. That is a little too terse for my taste, and it also makes template argument deduction a bit harder for the compiler, because in that case the first argument is an array but the second argument is a pointer. (Again, array-to-pointer decay kicks in.)
I think you want to refresh the fragment contents upon db update
If so, detach the fragment and reattach it
// Reload current fragment
Fragment frg = null;
frg = getSupportFragmentManager().findFragmentByTag("Your_Fragment_TAG");
final FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.detach(frg);
ft.attach(frg);
ft.commit();
Your_Fragment_TAG is the name you gave your fragment when you created it
This code is for support library.
If you're not supporting older devices, just use getFragmentManager instead of getSupportFragmentManager
[EDIT]
This method requires the Fragment to have a tag.
In case you don't have it, then @Hammer's method is what you need.
You should be able to use the /quiet
or /qn
options with msiexec
to perform a silent install.
MSI packages export public properties, which you can set with the PROPERTY=value
syntax on the end of the msiexec
parameters.
For example, this command installs a package with no UI and no reboot, with a log and two properties:
msiexec /i c:\path\to\package.msi /quiet /qn /norestart /log c:\path\to\install.log PROPERTY1=value1 PROPERTY2=value2
You can read the options for msiexec
by just running it with no options from Start -> Run.
I sometimes do a mysqldump and pipe the output into another mysql command to import it into a different database.
mysqldump --add-drop-table -u wordpress -p wordpress | mysql -u wordpress -p wordpress_backup
string[] files =
Directory.GetFiles(txtPath.Text, "*ProfileHandler.cs", SearchOption.AllDirectories);
That last parameter effects exactly what you're referring to. Set it to AllDirectories for every file including in subfolders, and set it to TopDirectoryOnly if you only want to search in the directory given and not subfolders.

I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application
Excerpt from the linked page:
Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:
Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.
Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the
Include
method.Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace
Collection(x => x.Courses)
withReference(x => x.Administrator)
.) Typically you'd use explicit loading only when you've turned lazy loading off.Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.
I do it like this, even though it looks like a hack it works every time:
ls_of_things = ['apple', 'car', 'truck', 'bike', 'banana']
first = 0
last = len(ls_of_things)
for items in ls_of_things:
if first == 0
first = first + 1
pass
elif first == last - 1:
break
else:
do_stuff
first = first + 1
pass
I'm adding an answer with the same direction as the accepted answer but with small (important) differences and adding more details.
Consider the configuration below:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": ["s3:ListBucket"],
"Resource": ["arn:aws:s3:::<Bucket-Name>"]
},
{
"Effect": "Allow",
"Action": [
"s3:PutObject",
"s3:DeleteObject"
],
"Resource": ["arn:aws:s3:::<Bucket-Name>/*"]
}
]
}
The policy grants programmatic write-delete access and is separated into two parts:
The ListBucket
action provides permissions on the bucket level and the other PutObject/DeleteObject
actions require permissions on the objects inside the bucket.
The first Resource element specifies arn:aws:s3:::<Bucket-Name>
for the ListBucket
action so that applications can list all objects in the bucket.
The second Resource element specifies arn:aws:s3:::<Bucket-Name>/*
for the PutObject
, and DeletObject
actions so that applications can write or delete any objects in the bucket.
The separation into two different 'arns' is important from security reasons in order to specify bucket-level and object-level fine grained permissions.
Notice that if I would have specified just GetObject
in the 2nd block what would happen is that in cases of programmatic access I would receive an error like:
Upload failed: <file-name> to <bucket-name>:<path-in-bucket> An error occurred (AccessDenied) when calling the PutObject operation: Access Denied
.
When you first read the body, you have to store it so once you're done with it, you can set a new io.ReadCloser
as the request body constructed from the original data. So when you advance in the chain, the next handler can read the same body.
One option is to read the whole body using ioutil.ReadAll()
, which gives you the body as a byte slice.
You may use bytes.NewBuffer()
to obtain an io.Reader
from a byte slice.
The last missing piece is to make the io.Reader
an io.ReadCloser
, because bytes.Buffer
does not have a Close()
method. For this you may use ioutil.NopCloser()
which wraps an io.Reader
, and returns an io.ReadCloser
, whose added Close()
method will be a no-op (does nothing).
Note that you may even modify the contents of the byte slice you use to create the "new" body. You have full control over it.
Care must be taken though, as there might be other HTTP fields like content-length and checksums which may become invalid if you modify only the data. If subsequent handlers check those, you would also need to modify those too!
If you also want to read the response body, then you have to wrap the http.ResponseWriter
you get, and pass the wrapper on the chain. This wrapper may cache the data sent out, which you can inspect either after, on on-the-fly (as the subsequent handlers write to it).
Here's a simple ResponseWriter
wrapper, which just caches the data, so it'll be available after the subsequent handler returns:
type MyResponseWriter struct {
http.ResponseWriter
buf *bytes.Buffer
}
func (mrw *MyResponseWriter) Write(p []byte) (int, error) {
return mrw.buf.Write(p)
}
Note that MyResponseWriter.Write()
just writes the data to a buffer. You may also choose to inspect it on-the-fly (in the Write()
method) and write the data immediately to the wrapped / embedded ResponseWriter
. You may even modify the data. You have full control.
Care must be taken again though, as the subsequent handlers may also send HTTP response headers related to the response data –such as length or checksums– which may also become invalid if you alter the response data.
Putting the pieces together, here's a full working example:
func loginmw(handler http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
body, err := ioutil.ReadAll(r.Body)
if err != nil {
log.Printf("Error reading body: %v", err)
http.Error(w, "can't read body", http.StatusBadRequest)
return
}
// Work / inspect body. You may even modify it!
// And now set a new body, which will simulate the same data we read:
r.Body = ioutil.NopCloser(bytes.NewBuffer(body))
// Create a response wrapper:
mrw := &MyResponseWriter{
ResponseWriter: w,
buf: &bytes.Buffer{},
}
// Call next handler, passing the response wrapper:
handler.ServeHTTP(mrw, r)
// Now inspect response, and finally send it out:
// (You can also modify it before sending it out!)
if _, err := io.Copy(w, mrw.buf); err != nil {
log.Printf("Failed to send out response: %v", err)
}
})
}
The official documentation provides the answer to this question! you can find it here.
{
"query": { "match_all": {} },
"size": 1
}
You simply replace size (1) with the number of results you want to see!
substring(field, 1,3) will work on your examples.
select substring(field, 1,3) from table
Also, if the alphabetic part is of variable length, you can do this to extract the alphabetic part:
select substring(field, 1, PATINDEX('%[1234567890]%', field) -1)
from table
where PATINDEX('%[1234567890]%', field) > 0
A static variable can get an initial value only one time. This means that if you have code such as "static int a=0
" in a sample function, and this code is executed in a first call of this function, but not executed in a subsequent call of the function; variable (a) will still have its current value (for example, a current value of 5), because the static variable gets an initial value only one time.
A constant variable has its value constant in whole of the code. For example, if you set the constant variable like "const int a=5
", then this value for "a" will be constant in whole of your program.
For a search routine you should look to use Find
, AutoFilter
or variant array approaches. Range loops are nomally too slow, worse again if they use Select
The code below will look for the strText variable in a user selected range, it then adds any matches to a range variable rng2
which you can then further process
Option Explicit
Const strText As String = "%"
Sub ColSearch_DelRows()
Dim rng1 As Range
Dim rng2 As Range
Dim rng3 As Range
Dim cel1 As Range
Dim cel2 As Range
Dim strFirstAddress As String
Dim lAppCalc As Long
'Get working range from user
On Error Resume Next
Set rng1 = Application.InputBox("Please select range to search for " & strText, "User range selection", Selection.Address(0, 0), , , , , 8)
On Error GoTo 0
If rng1 Is Nothing Then Exit Sub
With Application
lAppCalc = .Calculation
.ScreenUpdating = False
.Calculation = xlCalculationManual
End With
Set cel1 = rng1.Find(strText, , xlValues, xlPart, xlByRows, , False)
'A range variable - rng2 - is used to store the range of cells that contain the string being searched for
If Not cel1 Is Nothing Then
Set rng2 = cel1
strFirstAddress = cel1.Address
Do
Set cel1 = rng1.FindNext(cel1)
Set rng2 = Union(rng2, cel1)
Loop While strFirstAddress <> cel1.Address
End If
If Not rng2 Is Nothing Then
For Each cel2 In rng2
Debug.Print cel2.Address & " contained " & strText
Next
Else
MsgBox "No " & strText
End If
With Application
.ScreenUpdating = True
.Calculation = lAppCalc
End With
End Sub
Following worked for me in JSON config file:
"scripts": {
"start": "webpack-dev-server --host 127.0.0.1 --port 80 ./js/index.js"
},
I have created an Asset helper of my own.
First I defined the asset types and path in app/config/assets.php
:
return array(
/*
|--------------------------------------------------------------------------
| Assets paths
|--------------------------------------------------------------------------
|
| Location of all application assets, relative to the public folder,
| may be used together with absolute paths or with URLs.
|
*/
'images' => '/storage/images',
'css' => '/assets/css',
'img' => '/assets/img',
'js' => '/assets/js'
);
Then the actual Asset
class:
class Asset
{
private static function getUrl($type, $file)
{
return URL::to(Config::get('assets.' . $type) . '/' . $file);
}
public static function css($file)
{
return self::getUrl('css', $file);
}
public static function img($file)
{
return self::getUrl('img', $file);
}
public static function js($file)
{
return self::getUrl('js', $file);
}
}
So in my view I can do this to show an image:
{{ HTML::image(Asset::img('logo.png'), "My logo")) }}
Or like this to implement a Java script:
{{ HTML::script(Asset::js('my_script.js')) }}
A sort of block comment uses an if statement:
if(FALSE) {
all your code
}
It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).
Just go to follow link domain.com/wp-admin/about.php
setprecision(n)
applies to the entire number, not the fractional part. You need to use the fixed-point format to make it apply to the fractional part: setiosflags(ios::fixed)
Using lodash _.values(object)
_.values({"id": 1, "second": "abcd"})
[ 1, 'abcd' ]
lodash
includes a whole bunch of other functions to work with arrays, objects, collections, strings, and more that you wish were built into JavaScript (and actually seem to slowly be making their way into the language).
Use index=False
.
df.to_csv('your.csv', index=False)
You can use this function
function getParmFromUrl(url, parm) {
var re = new RegExp(".*[?&]" + parm + "=([^&]+)(&|$)");
var match = url.match(re);
return(match ? match[1] : "");
}
The reason I used a +
instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.
word[Aa]\s+word[Bb]\s+word[Cc]
will match:
wordA wordB wordC
worda wordb wordc
wordA wordb wordC
The words, in this expression, will have to be specific, and also in order (a, b, then c)
%timeit
is an ipython magic function, which can be used to time a particular piece of code (A single execution statement, or a single method).
From the docs:
%timeit
Time execution of a Python statement or expression Usage, in line mode: %timeit [-n<N> -r<R> [-t|-c] -q -p<P> -o] statement
To use it, for example if we want to find out whether using xrange
is any faster than using range
, you can simply do:
In [1]: %timeit for _ in range(1000): True
10000 loops, best of 3: 37.8 µs per loop
In [2]: %timeit for _ in xrange(1000): True
10000 loops, best of 3: 29.6 µs per loop
And you will get the timings for them.
The major advantage of %timeit
are:
that you don't have to import timeit.timeit
from the standard library, and run the code multiple times to figure out which is the better approach.
%timeit will automatically calculate number of runs required for your code based on a total of 2 seconds execution window.
You can also make use of current console variables without passing the whole code snippet as in case of timeit.timeit
to built the variable that is built in an another environment that timeit works.
I believe because cases must be constant values, the switch statement does the equivelent of a goto, so based on the value of the variable it jumps to the right case, whereas in the if/then statement it must evaluate each expression.
You can use Apache Commons StringUtils. It offers methods for padding strings:
StringUtils.leftPad(Integer.toBinaryString(1), 16, '0');
Short story: The 0
tells the parser it's dealing with a constant (and not an identifier/reserved word). Something is still needed to specify the number base: the x
is an arbitrary choice.
Long story: In the 60's, the prevalent programming number systems were decimal and octal — mainframes had 12, 24 or 36 bits per byte, which is nicely divisible by 3 = log2(8).
The BCPL language used the syntax 8 1234
for octal numbers. When Ken Thompson created B from BCPL, he used the 0
prefix instead. This is great because
0
is the same in both bases),00005 == 05
), and#123
).When C was created from B, the need for hexadecimal numbers arose (the PDP-11 had 16-bit words) and all of the points above were still valid. Since octals were still needed for other machines, 0x
was arbitrarily chosen (00
was probably ruled out as awkward).
C# is a descendant of C, so it inherits the syntax.
I had the same problem as I like using the Try-method-pattern which basically seems to be incompatible to the async-await-paradigm...
Important to me is that I can call the Try-method within a single if-clause and do not have to pre-define the out-variables before, but can do it in-line like in the following example:
if (TryReceive(out string msg))
{
// use msg
}
So I came up with the following solution:
Define a helper struct:
public struct AsyncOut<T, OUT>
{
private readonly T returnValue;
private readonly OUT result;
public AsyncOut(T returnValue, OUT result)
{
this.returnValue = returnValue;
this.result = result;
}
public T Out(out OUT result)
{
result = this.result;
return returnValue;
}
public T ReturnValue => returnValue;
public static implicit operator AsyncOut<T, OUT>((T returnValue ,OUT result) tuple) =>
new AsyncOut<T, OUT>(tuple.returnValue, tuple.result);
}
Define async Try-method like this:
public async Task<AsyncOut<bool, string>> TryReceiveAsync()
{
string message;
bool success;
// ...
return (success, message);
}
Call the async Try-method like this:
if ((await TryReceiveAsync()).Out(out string msg))
{
// use msg
}
For multiple out parameters you can define additional structs (e.g. AsyncOut<T,OUT1, OUT2>) or you can return a tuple.
this function help you to get parameter from URL in JS
function getQuery(q) {
return (window.location.search.match(new RegExp('[?&]' + q + '=([^&]+)')) || [, null])[1];
}
Could not get this to work until I put Authorization in single quotes:
axios.get(URL, { headers: { 'Authorization': AuthStr } })
string s2 = s1.Replace(",", ",\n") + ",....";
By the time the image is loaded, the renderer has already drawn the scene, hence it is too late. The solution is to change
texture = THREE.ImageUtils.loadTexture('crate.gif'),
into
texture = THREE.ImageUtils.loadTexture('crate.gif', {}, function() {
renderer.render(scene);
}),
The sequence being iterated in a foreach loop might not support indexing or know such a concept it just needs to implement a method called GetEnumerator that returns an object that as a minimum has the interface of IEnumerator though implmenting it is not required. If you know that what you iterate does support indexing and you need the index then I suggest to use a for
loop instead.
An example class that can be used in foreach
:
class Foo {
public iterator GetEnumerator() {
return new iterator();
}
public class iterator {
public Bar Current {
get{magic}
}
public bool MoveNext() {
incantation
}
}
}
Difference between String and the other two classes is that String is immutable and the other two are mutable classes.
But why we have two classes for same purpose?
Reason is that StringBuffer
is Thread safe and StringBuilder
is not.
StringBuilder
is a new class on StringBuffer Api

Very simple answer to this use this: \d*
for i=1,#target do
game.Players.target[i].Character:BreakJoints()
end
Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:
game.Players.target.1.Character:BreakJoints()
Which is completely incorrect.
c = game.Players:GetChildren()
Never use "Players:GetChildren()", it is not guaranteed to return only players.
Instead use:
c = Game.Players:GetPlayers()
if msg:lower()=="me" then
table.insert(people, source)
return people
Here you add the player's name in the list "people", where you in the other places adds the player object.
Fixed code:
local Admins = {"FakeNameHereSoNoStalkers"}
function Kill(Players)
for i,Player in ipairs(Players) do
if Player.Character then
Player.Character:BreakJoints()
end
end
end
function IsAdmin(Player)
for i,AdminName in ipairs(Admins) do
if Player.Name:lower() == AdminName:lower() then return true end
end
return false
end
function GetPlayers(Player,Msg)
local Targets = {}
local Players = Game.Players:GetPlayers()
if Msg:lower() == "me" then
Targets = { Player }
elseif Msg:lower() == "all" then
Targets = Players
elseif Msg:lower() == "others" then
for i,Plr in ipairs(Players) do
if Plr ~= Player then
table.insert(Targets,Plr)
end
end
else
for i,Plr in ipairs(Players) do
if Plr.Name:lower():sub(1,Msg:len()) == Msg then
table.insert(Targets,Plr)
end
end
end
return Targets
end
Game.Players.PlayerAdded:connect(function(Player)
if IsAdmin(Player) then
Player.Chatted:connect(function(Msg)
if Msg:lower():sub(1,6) == ":kill " then
Kill(GetPlayers(Player,Msg:sub(7)))
end
end)
end
end)
Now that Firefox Quantum 57 is out with substantial — and potentially breaking — improvements to Gecko collectively known as Stylo or Quantum CSS, you may find yourself in a situation where you have to distinguish between legacy versions of Firefox and Firefox Quantum.
From my answer here:
You can use
@supports
with acalc(0s)
expression in conjunction with@-moz-document
to test for Stylo — Gecko does not support time values incalc()
expressions but Stylo does:@-moz-document url-prefix() { @supports (animation: calc(0s)) { /* Stylo */ } }
Here's a proof-of-concept:
_x000D__x000D__x000D__x000D__x000D_body::before {_x000D_ content: 'Not Fx';_x000D_ }_x000D_ _x000D_ @-moz-document url-prefix() {_x000D_ body::before {_x000D_ content: 'Fx legacy';_x000D_ }_x000D_ _x000D_ @supports (animation: calc(0s)) {_x000D_ body::before {_x000D_ content: 'Fx Quantum';_x000D_ }_x000D_ }_x000D_ }
Targeting legacy versions of Firefox is a little tricky — if you're only interested in versions that support
@supports
, which is Fx 22 and up,@supports not (animation: calc(0s))
is all you need:@-moz-document url-prefix() { @supports not (animation: calc(0s)) { /* Gecko */ } }
... but if you need to support even older versions, you'll need to make use of the cascade, as demonstrated in the proof-of-concept above.
This is late, but worthwhile if it helps someone as I did not see it in Instagram's documentation.
To perform GET on https://api.instagram.com/v1/users/<user-id>/media/recent/
(at present time of writing) you actually do not need OAuth access token.
You can perform https://api.instagram.com/v1/users/[USER ID]/media/recent/?client_id=[CLIENT ID]
[CLIENT ID] would be valid client id registered in app through manage clients (not related to user whatsoever).
You can get [USER ID] from username by performing GET users search request:
https://api.instagram.com/v1/users/search?q=[USERNAME]&client_id=[CLIENT ID]
for (int i = 0; i < a.length; i++) {
for (int k = 0; k < a.length; k++) {
if (a[i] != a[k]) {
System.out.println(a[i] + " not the same with " + a[k + 1] + "\n");
}
}
}
You can start from k=1 & keep "a.length-1" in outer for loop, in order to reduce two comparisions,but that doesnt make any significant difference.
It's limited in that you can't put statements in there. You can only put values(or things that return/evaluate to values), to return
This works ('a' is a static int within class Blah)
Blah.a=Blah.a<5?1:8;
(round brackets are impicitly between the equals and the question mark).
This doesn't work.
Blah.a = Blah.a < 4 ? Console.WriteLine("asdf") : Console.WriteLine("34er");
or
Blah.a = Blah.a < 4 ? MessageBox.Show("asdf") : MessageBox.Show("34er");
So you can only use the c# ternary operator for returning values. So it's not quite like a shortened form of an if. Javascript and perhaps some other languages let you put statements in there.
You shall pass a this
pointer to tell the function which object to work on because it relies on that as opposed to a static
member function.
If your margin is set on the body, then setting the background color of the html tag should color the margin area
html { background-color: black; }
body { margin:50px; background-color: white; }
Or as dmackerman suggestions, set a margin of 0, but a border of the size you want the margin to be and set the border-color
Try: Controls("Check Box 1") = True
You can use the following code:
String in = "i have a male cat. the color of male cat is Black";
int i = 0;
Pattern p = Pattern.compile("male cat");
Matcher m = p.matcher( in );
while (m.find()) {
i++;
}
System.out.println(i); // Prints 2
It matches "male cat"
.
while(m.find())
indicates, do whatever is given inside the loop while m
finds a match.
And I'm incrementing the value of i
by i++
, so obviously, this gives number of male cat
a string has got.
you can use the Utility mettod. Arrays.deeptoString();
public static void main(String[] args) {
int twoD[][] = new int[4][];
twoD[0] = new int[1];
twoD[1] = new int[2];
twoD[2] = new int[3];
twoD[3] = new int[4];
System.out.println(Arrays.deepToString(twoD));
}
The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.
The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.
The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.
Edit: Also worth a look - kashif's comment about json-streamer
and Henrik Heino's comment about bigjson
.
For those who rooted the Android device with Magisk, you can install adb_root from https://github.com/evdenis/adb_root. Then adb root

Using jQuery, easiest way to get array of keys from object is following:
$.map(obj, function(element,index) {return index})
In your case, it will return this array: ["alfa", "beta"]
In my experience the plugins worked with http but not with the latest httpClient. Also, configuring the CORS respsonse headers on the server wasn't really an option. So, I created a proxy.conf.json file to act as a proxy server.
Read more about this here: https://github.com/angular/angular-cli/blob/master/docs/documentation/stories/proxy.md
below is my prox.conf.json file
{
"/posts": {
"target": "https://example.com",
"secure": true,
"pathRewrite": {
"^/posts": ""
},
"changeOrigin": true
}
}
I placed the proxy.conf.json file right next the the package.json file in the same directory
then I modified the start command in the package.json file like below
"start": "ng serve --proxy-config proxy.conf.json"
now, the http call from my app component is as follows
return this._http.get('/posts/pictures?method=GetPictures')
.subscribe((returnedStuff) => {
console.log(returnedStuff);
});
Lastly to run my app, I'd have to use npm start or ng serve --proxy-config proxy.conf.json
It depends on how and where you declared your array list. If it is an instance variable in the same class like your AnalyseArray() method you don't have to pass it along. The method will know the list and you can simply use the A in whatever purpose you need.
If they don't know each other, e.g. beeing a local variable or declared in a different class, define that your AnalyseArray() method needs an ArrayList parameter
public void AnalyseArray(ArrayList<Integer> theList){}
and then work with theList inside that method. But don't forget to actually pass it on when calling the method.AnalyseArray(A);
PS: Some maybe helpful Information to Variables and parameters.
Using system("pause");
is Ungood Practice™ because
It's completely unnecessary.
To keep the program's console window open at the end when you run it from Visual Studio, use Ctrl+F5 to run it without debugging, or else place a breakpoint at the last right brace }
of main
. So, no problem in Visual Studio. And of course no problem at all when you run it from the command line.
It's problematic & annoying
when you run the program from the command line. For interactive execution you have to press a key at the end to no purpose whatsoever. And for use in automation of some task that pause
is very much undesired!
It's not portable.
Unix-land has no standard pause
command.
The pause
command is an internal cmd.exe
command and can't be overridden, as is erroneously claimed in at least one other answer. I.e. it's not a security risk, and the claim that AV programs diagnose it as such is as dubious as the claim of overriding the command (after all, a C++ program invoking system
is in position to do itself all that the command interpreter can do, and more). Also, while this way of pausing is extremely inefficient by the usual standards of C++ programming, that doesn't matter at all at the end of a novice's program.
So, the claims in the horde of answers before this are not correct, and the main reason you shouldn't use system("pause")
or any other wait command at the end of your main
, is the first point above: it's completely unnecessary, it serves absolutely no purpose, it's just very silly.
You don't show the code for display_data
, but here's what you need to do:
print "$%0.02f" %amount
This is a format specifier for the variable amount
.
Since this is beginner topic, I won't get into floating point rounding error, but it's good to be aware that it exists.
string input = "this is a test";
string[] afterSplit = input.Split();
foreach (var word in afterSplit)
Console.WriteLine(word);
Result:
this
is
a
test
For complex splitting you could use a regex creating a match collection.
In addition to the Eclipse solutions and the tool mentioned in another answer, consider flip. It can 'flip' either way between normal and Windows linebreaks, and does nice things like preserve the file's timestamp and other stats.
You can use it like this to solve your problem:
find . -type f -not -path './.git/*' -exec flip -u {} \;
(I put in a clause to ignore your .git directory, in case you use git, but since flip ignores binary files by default, you mightn't need this.)
Usage:
control.InvokeIfRequired(c => c.Visible = false);
return control.InvokeIfRequired(c => {
c.Visible = value
return c.Visible;
});
Code:
using System;
using System.ComponentModel;
namespace Extensions
{
public static class SynchronizeInvokeExtensions
{
public static void InvokeIfRequired<T>(this T obj, Action<T> action)
where T : ISynchronizeInvoke
{
if (obj.InvokeRequired)
{
obj.Invoke(action, new object[] { obj });
}
else
{
action(obj);
}
}
public static TOut InvokeIfRequired<TIn, TOut>(this TIn obj, Func<TIn, TOut> func)
where TIn : ISynchronizeInvoke
{
return obj.InvokeRequired
? (TOut)obj.Invoke(func, new object[] { obj })
: func(obj);
}
}
}
Can also use groupby() with no need to join and stack().
Use above example data:
import pandas as pd
import numpy as np
df = pd.DataFrame({'ItemQty': {0: 3, 1: 25},
'Seatblocks': {0: '2:218:10:4,6', 1: '1:13:36:1,12 1:13:37:1,13'},

There's a BeyondCompare plugin as well. It opens the 2 files in a BeyondCompare
window. Pretty convenient to open files from the sublime window.
You will need BC3 installation present in the system. After installing the plugin, you will have to provide the path to the installation.
Example:
{
//Define a custom path to beyond compare
"beyond_compare_path": "G:/Softwares/Beyond Compare 3/BCompare.exe"
}
Based on this page:
l = list(...)
if item in l:
l.remove(item) # checks if the item to be moved is present in the list
l.insert(new_index,item)
something like this:
public int PowerRating
{
get { return base.PowerRating; } // if power inherits from meter...
}
Two options:
VLOOKUP
function in its own cell: =VLOOKUP(A1, B:B, 1, 0)
(in say, C1), then formula referencing C1: =IF( C1 > 10, C1 - 10, C1 )
Function MyFunc(a1, a2, a3, a4)
Dim v as Variant
v = Application.WorksheetFunction.VLookup(a1, a2, a3, a4)
If v > 10 Then
MyFunc = v - 10
Else
MyFunc = v
End If
End Function
I guess problem is in width attributes in table and td remove 'px' for example
<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">
Should be
<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">
In, Swift 3.0 you have set date object for this way.
extension Date
{
init(dateString:String) {
let dateStringFormatter = DateFormatter()
dateStringFormatter.dateFormat = "yyyy-MM-dd"
dateStringFormatter.locale = Locale(identifier: "en_US_POSIX")
let d = dateStringFormatter.date(from: dateString)!
self(timeInterval:0, since:d)
}
}

In your concrete example the problem is that you don't use this construct correctly:
@JsonSubTypes({ @JsonSubTypes.Type(value = MyAbstractClass.class, name = "MyAbstractClass") })
@JsonSubTypes.Type
should contain the actual non-abstract subtypes of your abstract class.
Therefore if you have:
abstract class Parent
and the concrete subclasses
Ch1 extends Parent
and
Ch2 extends Parent
Then your annotation should look like:
@JsonSubTypes({
@JsonSubTypes.Type(value = Ch1.class, name = "ch1"),
@JsonSubTypes.Type(value = Ch2.class, name = "ch2")
})
Here name
should match the value of your 'discriminator':
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.WRAPPER_OBJECT,
property = "type")
in the property
field, here it is equal to type
. So type
will be the key and the value you set in name
will be the value.
Therefore, when the json string comes if it has this form:
{
"type": "ch1",
"other":"fields"
}
Jackson will automatically convert this to a Ch1
class.
If you send this:
{
"type": "ch2",
"other":"fields"
}
You would get a Ch2
instance.
Its 2020 and lots of you will come here looking for a similar solution but with Hooks ( They are great! ) and with latest approaches in terms of code cleanliness and syntax.
So as previous answers had stated, the best approach to this kind of problem is to hold the state outside of child component fieldEditor
.
You could do that in multiple ways.
The most "complex" is with global context (state) that both parent and children could access and modify. Its a great solution when components are very deep in the tree hierarchy and so its costly to send props in each level.
In this case I think its not worth it, and more simple approach will bring us the results we want, just using the powerful React.useState()
.
As said we will deal with changes and store the data of our child component fieldEditor
in our parent fieldForm
. To do that
we will send a reference to the function that will deal and apply the changes to the fieldForm
state, you could do that with:
function FieldForm({ fields }) {
const [fieldsValues, setFieldsValues] = React.useState({});
const handleChange = (event, fieldId) => {
let newFields = { ...fieldsValues };
newFields[fieldId] = event.target.value;
setFieldsValues(newFields);
};
return (
<div>
{fields.map(field => (
<FieldEditor
key={field}
id={field}
handleChange={handleChange}
value={fieldsValues[field]}
/>
))}
<div>{JSON.stringify(fieldsValues)}</div>
</div>
);
}
Note that React.useState({})
will return an array with position 0 being the value specified on call (Empty object in this case), and position 1 being the reference to the function
that modifies the value.
Now with the child component, FieldEditor
, you don't even need to create a function with a return statement, a lean constant with an arrow function
will do!
const FieldEditor = ({ id, value, handleChange }) => (
<div className="field-editor">
<input onChange={event => handleChange(event, id)} value={value} />
</div>
);
Aaaaand we are done, nothing more, with just these two slime functional components we have our end goal "access" our child FieldEditor
value and show it off in our parent.
You could check the accepted answer from 5 years ago and see how Hooks made React code leaner (By a lot!).
Hope my answer helps you learn and understand more about Hooks, and if you want to check a working example here it is.
Here's an alternative in case you need to save the value to a variable:
var _t = $('#c_b :checkbox:checked').map(function() {
return $(this).val();
});
$('#t').append(_t.join(','));
(map() returns an array, which I find handier than the text in textarea).
SQL Server (2005, 2000, 7.0) does not have any flexible, or even non-flexible, way of taking an arbitrarily structured datetime in string format and converting it to the datetime data type.
By "arbitrarily", I mean "a form that the person who wrote it, though perhaps not you or I or someone on the other side of the planet, would consider to be intuitive and completely obvious." Frankly, I'm not sure there is any such algorithm.
I landed here with the same issue, then figured it out on my own. This weird character was appearing with my HTML.
The issue is most likely your code editor. I use Espresso and sometimes run into issues like this.
To fix it, simply highlight the affected code, then go to the menu and click "convert to numeric entities". You'll see the numeric value of this character appear; simply delete it and it's gone forever.
This is array initializer syntax, and it can only be used on the right-hand-side when declaring a variable of array type. Example:
int[] x = {1,2,3,4};
String y = {"a","b","c"};
If you're not on the RHS of a variable declaration, use an array constructor instead:
int[] x;
x = new int[]{1,2,3,4};
String y;
y = new String[]{"a","b","c"};
These declarations have the exact same effect: a new array is allocated and constructed with the specified contents.
In your case, it might actually be clearer (less repetitive, but a bit less concise) to specify the table programmatically:
double[][] m = new double[4][4];
for(int i=0; i<4; i++) {
for(int j=0; j<4; j++) {
m[i][j] = i*j;
}
}
For PHP 8 or newer, use the str_starts_with
function:
str_starts_with('http://www.google.com', 'http')
You can use the method SelectTab
.
There are 3 versions:
public void SelectTab(int index);
public void SelectTab(string tabPageName);
public void SelectTab(TabPage tabPage);
Add multiple lines : use @
string query = @"SELECT foo, bar
FROM table
WHERE id = 42";
Add String Values to the middle : use $
string text ="beer";
string query = $"SELECT foo {text} bar ";
Multiple line string Add Values to the middle: use $@
string text ="Customer";
string query = $@"SELECT foo, bar
FROM {text}Table
WHERE id = 42";
Working with jQuery 1.10.2, this pulses a dropdown twice and changes the text to an error. It also stores the values for the changed attributes to reinstate them.
// shows the user an error has occurred
$("#myDropdown").fadeOut(700, function(){
var text = $(this).find("option:selected").text();
var background = $(this).css( "background" );
$(this).css('background', 'red');
$(this).find("option:selected").text("Error Occurred");
$(this).fadeIn(700, function(){
$(this).fadeOut(700, function(){
$(this).fadeIn(700, function(){
$(this).fadeOut(700, function(){
$(this).find("option:selected").text(text);
$(this).css("background", background);
$(this).fadeIn(700);
})
})
})
})
});
Done via callbacks - to ensure no animations are missed.
Another minimalist Python solution without using numpy:
[0 if i < 0 else i for i in a]
No need to define any extra functions.
a = [1, 2, 3, -4, -5.23, 6]
[0 if i < 0 else i for i in a]
yields:
[1, 2, 3, 0, 0, 6]
There are 3 ways:
You can find examples from here.
Buffers can be used for taking a string or piece of data and doing base64 encoding of the result. For example:
> console.log(Buffer.from("Hello World").toString('base64'));
SGVsbG8gV29ybGQ=
> console.log(Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('ascii'))
Hello World
Buffers are a global object, so no require is needed. Buffers created with strings can take an optional encoding parameter to specify what encoding the string is in. The available toString
and Buffer
constructor encodings are as follows:
'ascii' - for 7 bit ASCII data only. This encoding method is very fast, and will strip the high bit if set.
'utf8' - Multi byte encoded Unicode characters. Many web pages and other document formats use UTF-8.
'ucs2' - 2-bytes, little endian encoded Unicode characters. It can encode only BMP(Basic Multilingual Plane, U+0000 - U+FFFF).
'base64' - Base64 string encoding.
'binary' - A way of encoding raw binary data into strings by using only the first 8 bits of each character. This encoding method is deprecated and should be avoided in favor of Buffer objects where possible. This encoding will be removed in future versions of Node.
The answers above were all assuming your Python distribution would have some third-party libraries in order to achieve the "one liner python ftpd" goal, but that is not the case of what @zio was asking. Also, SimpleHTTPServer involves web broswer for downloading files, it's not quick enough.
Python can't do ftpd by itself, but you can use netcat, nc
:
nc
is basically a built-in tool from any UNIX-like systems (even embedded systems), so it's perfect for "quick and temporary way to transfer files".
Step 1, on the receiver side, run:
nc -l 12345 | tar -xf -
this will listen on port 12345, waiting for data.
Step 2, on the sender side:
tar -cf - ALL_FILES_YOU_WANT_TO_SEND ... | nc $RECEIVER_IP 12345
You can also put pv
in the middle to monitor the progress of transferring:
tar -cf - ALL_FILES_YOU_WANT_TO_SEND ...| pv | nc $RECEIVER_IP 12345

There's a truly horrifying amount of ancient code out there in the wild, much of it in the form of common CPAN modules. I've found I have to be fairly careful enabling Unicode if I use external modules that might be affected by it, and am still trying to identify and fix some Unicode-related failures in several Perl scripts I use regularly (in particular, iTiVo fails badly on anything that's not 7-bit ASCII due to transcoding issues).

Take a look at Beaker:
To access field or method of an object use dot .
:
user = User()
print user.fullName
If a name of the field will be defined at run time, use buildin getattr
function:
field_name = "fullName"
print getattr(user, field_name) # prints content of user.fullName
You can use the return
statement inside a stored procedure to return an integer status code (and only of integer type). By convention a return value of zero is used for success.
If no return
is explicitly set, then the stored procedure returns zero.
CREATE PROCEDURE GetImmediateManager
@employeeID INT,
@managerID INT OUTPUT
AS
BEGIN
SELECT @managerID = ManagerID
FROM HumanResources.Employee
WHERE EmployeeID = @employeeID
if @@rowcount = 0 -- manager not found?
return 1;
END
And you call it this way:
DECLARE @return_status int;
DECLARE @managerID int;
EXEC @return_status = GetImmediateManager 2, @managerID output;
if @return_status = 1
print N'Immediate manager not found!';
else
print N'ManagerID is ' + @managerID;
go
You should use the return value for status codes only. To return data, you should use output parameters.
If you want to return a dataset, then use an output parameter of type cursor
.
$('myObject').css({'background-image': 'url(imgUrl)',});
What do you get when you do puts lines
? That will give you a clue.
By default File.open
opens the file in text mode, so your \r\n
characters will be automatically converted to \n
. Maybe that's the reason lines
are always equal to lines2
. To prevent Ruby from parsing the line ends use the rb
mode:
C:\> copy con lala.txt a file with many lines ^Z C:\> irb irb(main):001:0> text = File.open('lala.txt').read => "a\nfile\nwith\nmany\nlines\n" irb(main):002:0> bin = File.open('lala.txt', 'rb').read => "a\r\nfile\r\nwith\r\nmany\r\nlines\r\n" irb(main):003:0>
But from your question and code I see you simply need to open the file with the default modifier. You don't need any conversion and may use the shorter File.read
.

From the documentation. The develop
will not install the package but it will create a .egg-link
in the deployment directory back to the project source code directory.
So it's like installing but instead of copying to the site-packages
it adds a symbolic link (the .egg-link
acts as a multiplatform symbolic link).
That way you can edit the source code and see the changes directly without having to reinstall every time that you make a little change. This is useful when you are the developer of that project hence the name develop
. If you are just installing someone else's package you should use install
You can use HTML5 Websockets to introduce your own push messages. From Wikipedia:
"For the client side, WebSocket was to be implemented in Firefox 4, Google Chrome 4, Opera 11, and Safari 5, as well as the mobile version of Safari in iOS 4.2. Also the BlackBerry Browser in OS7 supports WebSockets."
To do this, you need your own provider server to push the messages to the clients.
If you want to use APN (Apple Push Notification) or C2DM (Cloud to Device Message), you must have a native application which must be downloaded through the online store.
No.
The content-type should be whatever it is known to be, if you know it. application/octet-stream
is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.
You can combine the use of Content-Disposition
with other content-types, such as image/png
or even text/html
to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html
but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).
RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline
to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename
part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.
Hence:
Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"
Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".
Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"
Means "This is a PNG image. Please save it as a file, preferably named picture.png".
Content-Type: image/png
Content-Disposition: inline; filename="picture.png"
Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".
Of those browsers that recognise inline
some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.

When i had the same problem, i stoped my mongo server and started it again with command
mongod --repair
Before running repair operation you should check do you have enough free space on your HDD (min - is the size of your database)
There's another way to fix above error. Try this, it fixed it for me. Open Terminal and run:
cd ~
mv .itmstransporter/ .old_itmstransporter/
"/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"
Three above code line will update iTMSTransporter, then you can try uploading in XCode again.

Finally I have found the solution by using the following code:
$('body').on('click', '#upload', function(e){
e.preventDefault();
var formData = new FormData($(this).parents('form')[0]);
$.ajax({
url: 'upload.php',
type: 'POST',
xhr: function() {
var myXhr = $.ajaxSettings.xhr();
return myXhr;
},
success: function (data) {
alert("Data Uploaded: "+data);
},
data: formData,
cache: false,
contentType: false,
processData: false
});
return false;
});
You can build even a tag type, for example 1.2.3-alpha43
, using wildcards:
Refspec: +refs/tags/*:refs/remotes/origin/tags/*
Branch specifier: origin/tags/1.2.3-alpha*
You can also tick "Build when a change is pushed to GitHub" to trigger the push, but you have to add "create" action to the webhook
See ?merge
:
the name "row.names" or the number 0 specifies the row names.
Example:
R> de <- merge(d, e, by=0, all=TRUE) # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0 # replace NA values
R> de

You need to
#include <string>
<iostream>
declares cout
, cin
, not string
.
Solr currently checks for a "pure negative" query and inserts *:*
(which matches all documents) so that it works correctly.
-foo
is transformed by solr into (*:* -foo)
The big caveat is that Solr only checks to see if the top level query is a pure negative query!
So this means that a query like bar OR (-foo)
is not changed since the pure negative query is in a sub-clause of the top level query. You need to transform this query yourself into bar OR (*:* -foo)
You may check the solr query explanation to verify the query transformation:
?q=-title:foo&debug=query
is transformed to
(+(-title:foo +MatchAllDocsQuery(*:*))
The solution can be boiled down to this:
var el=$('#follow-scroll');
var elpos=el.offset().top;
$(window).scroll(function () {
var y=$(this).scrollTop();
if(y<elpos){el.stop().animate({'top':0},500);}
else{el.stop().animate({'top':y-elpos},500);}
});
I have changed the assignment of el
because finding a single element by class is not a great habit to get in to; if you only want one element find it by id, if you want to iterate over a collection of elements then find them by class.

I had accidentally added a space character on the end of the name. Many hours of trying things before I finally noticed it. It's always something simple after you figure it out.
They provide the capability to extend existing types by adding new methods with no modifications necessary to the type. Calling methods from objects of the extended type within an application using instance method syntax is known as ‘‘extending’’ methods. Extension methods are not instance members on the type. The key point to remember is that extension methods, defined as static methods, are in scope only when the namespace is explicitly imported into your application source code via the using directive. Even though extension methods are defined as static methods, they are still called using instance syntax.
Check the full example here http://www.dotnetreaders.com/articles/Extension_methods_in_C-sharp.net,Methods_in_C_-sharp/201
Example:
class Extension
{
static void Main(string[] args)
{
string s = "sudhakar";
Console.WriteLine(s.GetWordCount());
Console.ReadLine();
}
}
public static class MyMathExtension
{
public static int GetWordCount(this System.String mystring)
{
return mystring.Length;
}
}
Looks like someone else found it: What are the default font characteristics in Android ?
There someone discovered the default text size, for TextViews (which use TextAppearance.Small) it's 14sp.
// The string must contain at least one special character, escaping reserved RegEx characters to avoid conflict
const hasSpecial = password => {
const specialReg = new RegExp(
'^(?=.*[!@#$%^&*"\\[\\]\\{\\}<>/\\(\\)=\\\\\\-_´+`~\\:;,\\.€\\|])',
);
return specialReg.test(password);

Try the following code to verify whether the file exist. You can create a user function and use it in your stored procedure. modify it as you need:
Set NOCOUNT ON
DECLARE @Filename NVARCHAR(50)
DECLARE @fileFullPath NVARCHAR(100)
SELECT @Filename = N'LogiSetup.log'
SELECT @fileFullPath = N'C:\LogiSetup.log'
create table #dir
(output varchar(2000))
DECLARE @cmd NVARCHAR(100)
SELECT @cmd = 'dir ' + @fileFullPath
insert into #dir
exec master.dbo.xp_cmdshell @cmd
--Select * from #dir
-- This is risky, as the fle path itself might contain the filename
if exists (Select * from #dir where output like '%'+ @Filename +'%')
begin
Print 'File found'
--Add code you want to run if file exists
end
else
begin
Print 'No File Found'
--Add code you want to run if file does not exists
end
drop table #dir
If you have converted your form from plain HTML to twig, be sure you didn't miss deleting a closing </form>
tag. Silly mistake, but as I discovered it's a possible cause for this problem.
When I got this error, I couldn't figure it out at first. I'm using form_start()
and form_end()
to generate the form, so I shouldn't have to explicitly add the token with form_row(form._token)
, or use form_rest()
to get it. It should have already been added automatically by form_end()
.
The problem was, the view I was working with was one that I had converted from plain HTML to twig, and I had missed deleting the closing </form>
tag, so instead of :
{{ form_end(form) }}
I had:
</form>
{{ form_end(form) }}
That actually seems like something that might throw an error, but apparently it doesn't, so when form_end()
outputs form_rest()
, the form is already closed. The actual generated page source of the form was like this:
<form>
<!-- all my form fields... -->
</form>
<input type="hidden" id="item__token" name="item[_token]" value="SQAOs1xIAL8REI0evGMjOsatLbo6uDzqBjVFfyD0PE4" />
</form>
Obviously the solution is to delete the extra closing tag and maybe drink some more coffee.
To extend @Dave's answer...if planRec.approved_by is already a string
this.approved_by = planRec.approved_by ?? "";
Also you are trying to set value2 using Set keyword, which is not required. You can directly use rng.value2 = 1
below test code for ref.
Sub test()
Dim rng As Range
Set rng = Range("A1")
rng.Value2 = 1
End Sub
When already given posts answer the question, I made a small change by adding the column name on which the max() function is applied for better code readability.
df.groupby('A', as_index=False)['B'].max()
Using this to push it to the remote upstream branch solved this issue for me:
git push <remote> master:origin/master
The remote had no access to the upstream repo so this was a good way to get the latest changes into that remote
From similar question DB2 - find and compare the lentgh of the value in a table field - add RTRIM since LENGTH will return length of column definition. This should be correct:
select * from table where length(RTRIM(fieldName))=10
UPDATE 27.5.2019: maybe on older db2 versions the LENGTH function returned the length of column definition. On db2 10.5 I have tried the function and it returns data length, not column definition length:
select fieldname
, length(fieldName) len_only
, length(RTRIM(fieldName)) len_rtrim
from (values (cast('1234567890 ' as varchar(30)) ))
as tab(fieldName)
FIELDNAME LEN_ONLY LEN_RTRIM
------------------------------ ----------- -----------
1234567890 12 10
One can test this by using this term:
where length(fieldName)!=length(rtrim(fieldName))
KEY
is normally a synonym for INDEX
. The key attribute PRIMARY KEY
can also be specified as just KEY
when given in a column definition. This was implemented for compatibility with other database systems.
column_definition:
data_type [NOT NULL | NULL] [DEFAULT default_value]
[AUTO_INCREMENT] [UNIQUE [KEY] | [PRIMARY] KEY]
...

%>%
is similar to pipe in Unix. For example, in
a <- combined_data_set %>% group_by(Outlet_Identifier) %>% tally()
the output of combined_data_set
will go into group_by
and its output will go into tally
, then the final output is assigned to a
.
This gives you handy and easy way to use functions in series without creating variables and storing intermediate values.
A few words on "what is makeinfo" -- other answers cover "how do I get it" well.
The section "Creating an Info File" of the Texinfo manual states that
makeinfo
is a program that converts a Texinfo file into an Info file, HTML file, or plain text.
The Texinfo home page explains that Texinfo itself "is the official documentation format of the GNU project" and that it "uses a single source file to produce output in a number of formats, both online and printed (dvi, html, info, pdf, xml, etc.)".
To sum up: Texinfo is a documentation source file format and makeinfo
is the program that turns source files in Texinfo format into the desired output.
Thanks, finally got an solution to not put utf8::encode all over code. To synthesize and complete for other cases, like write and read files in utf8 and also works with LoadFile of an YAML file in utf8
use utf8;
use open ':encoding(utf8)';
binmode(STDOUT, ":utf8");
open(FH, ">test.txt");
print FH "something éá";
use YAML qw(LoadFile Dump);
my $PUBS = LoadFile("cache.yaml");
my $f = "2917";
my $ref = $PUBS->{$f};
print "$f \"".$ref->{name}."\" ". $ref->{primary_uri}." ";
where cache.yaml is:
---
2917:
id: 2917
name: Semanário
primary_uri: 2917.xml
You could write a function template back
that delegates to the member function for ordinary containers and a normal function that implements the missing functionality for strings:
template <typename C>
typename C::reference back(C& container)
{
return container.back();
}
template <typename C>
typename C::const_reference back(const C& container)
{
return container.back();
}
char& back(std::string& str)
{
return *(str.end() - 1);
}
char back(const std::string& str)
{
return *(str.end() - 1);
}
Then you can just say back(foo)
without worrying whether foo
is a string or a vector.
I'll answer this question in Go because Go does not have a rich a lot of collections in its standard library.
Since a stack is really easy to implement I thought I'd try and use two stacks to accomplish a double ended queue. To better understand how I arrived at my answer I've split the implementation in two parts, the first part is hopefully easier to understand but it's incomplete.
type IntQueue struct {
front []int
back []int
}
func (q *IntQueue) PushFront(v int) {
q.front = append(q.front, v)
}
func (q *IntQueue) Front() int {
if len(q.front) > 0 {
return q.front[len(q.front)-1]
} else {
return q.back[0]
}
}
func (q *IntQueue) PopFront() {
if len(q.front) > 0 {
q.front = q.front[:len(q.front)-1]
} else {
q.back = q.back[1:]
}
}
func (q *IntQueue) PushBack(v int) {
q.back = append(q.back, v)
}
func (q *IntQueue) Back() int {
if len(q.back) > 0 {
return q.back[len(q.back)-1]
} else {
return q.front[0]
}
}
func (q *IntQueue) PopBack() {
if len(q.back) > 0 {
q.back = q.back[:len(q.back)-1]
} else {
q.front = q.front[1:]
}
}
It's basically two stacks where we allow the bottom of the stacks to be manipulated by each other. I've also used the STL naming conventions, where the traditional push, pop, peek operations of a stack have a front/back prefix whether they refer to the front or back of the queue.
The issue with the above code is that it doesn't use memory very efficiently. Actually, it grows endlessly until you run out of space. That's really bad. The fix for this is to simply reuse the bottom of the stack space whenever possible. We have to introduce an offset to track this since a slice in Go cannot grow in the front once shrunk.
type IntQueue struct {
front []int
frontOffset int
back []int
backOffset int
}
func (q *IntQueue) PushFront(v int) {
if q.backOffset > 0 {
i := q.backOffset - 1
q.back[i] = v
q.backOffset = i
} else {
q.front = append(q.front, v)
}
}
func (q *IntQueue) Front() int {
if len(q.front) > 0 {
return q.front[len(q.front)-1]
} else {
return q.back[q.backOffset]
}
}
func (q *IntQueue) PopFront() {
if len(q.front) > 0 {
q.front = q.front[:len(q.front)-1]
} else {
if len(q.back) > 0 {
q.backOffset++
} else {
panic("Cannot pop front of empty queue.")
}
}
}
func (q *IntQueue) PushBack(v int) {
if q.frontOffset > 0 {
i := q.frontOffset - 1
q.front[i] = v
q.frontOffset = i
} else {
q.back = append(q.back, v)
}
}
func (q *IntQueue) Back() int {
if len(q.back) > 0 {
return q.back[len(q.back)-1]
} else {
return q.front[q.frontOffset]
}
}
func (q *IntQueue) PopBack() {
if len(q.back) > 0 {
q.back = q.back[:len(q.back)-1]
} else {
if len(q.front) > 0 {
q.frontOffset++
} else {
panic("Cannot pop back of empty queue.")
}
}
}
It's a lot of small functions but of the 6 functions 3 of them are just mirrors of the other.
Add the code, inside the method
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject:AnyObject]?) -> Bool {
application.statusBarHidden = true
return true
}
DONE! Run your app and no more status bar!

There! The debate is settled!
It could be something like that:
var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];
var arrays = [], size = 3;
while (a.length > 0)
arrays.push(a.splice(0, size));
console.log(arrays);

See splice Array's method.
It's necessary because, more or less, when we import a project from git, it's not a maven project, so the maven dependencies are not in the build path.
Here's what I have done to turn a general project to a maven project.
general project-->java project right click the project, properties->project facets, click "java". This step will turn a general project into java project.
java project --> maven project right click project, configure-->convert to maven project At this moment, maven dependencies lib are still not in the build path. project properties, build path, add library, add maven dependencies lib
And wait a few seconds, when the dependencies are loaded, the project is ready!
I resolved this problem by renaming the DLL. The DLL had been manually renamed when it was uploaded to its shared location (a version number was appended to the file name). Removing the version number from the downloaded file resolved the issue.
There is an unnecessary hashtag; change the code to this:
var e = document.getElementById("ticket_category_clone").value;
You can't force the String arrays to have a specific size. You can do this:
private List<String[]> addresses = new ArrayList<String[]>();
but an array of any size can be added to this list.
However, as others have mentioned, the correct thing to do here is to create a separate class representing addresses. Then you would have something like:
private List<Address> addresses = new ArrayList<Address>();

: If you need to update a GUI component from a non-GUI thread, you can use that to put your update in a queue and it will be handled by the GUI thread as soon as possible.Task
implements the Worker
interface which is used when you need to run a long task outside the GUI thread (to avoid freezing your application) but still need to interact with the GUI at some stage.If you are familiar with Swing, the former is equivalent to SwingUtilities.invokeLater
and the latter to the concept of SwingWorker
.
The javadoc of Task gives many examples which should clarify how they can be used. You can also refer to the tutorial on concurrency.

Here is how removed special characters.
I simply applied regex
Dim strPattern As String: strPattern = "[^a-zA-Z0-9]" 'The regex pattern to find special characters
Dim strReplace As String: strReplace = "" 'The replacement for the special characters
Set regEx = CreateObject("vbscript.regexp") 'Initialize the regex object
Dim GCID As String: GCID = "Text #N/A" 'The text to be stripped of special characters
' Configure the regex object
With regEx
.Global = True
.MultiLine = True
.IgnoreCase = False
.Pattern = strPattern
End With
' Perform the regex replacement
GCID = regEx.Replace(GCID, strReplace)
if you're using React I found 'react-moment'
library more easy to handle for Front-End related tasks, just import <Moment>
component and add unix
prop:
import Moment from 'react-moment'
// get date variable
const {date} = this.props
<Moment unix>{date}</Moment>
Please note that IDEs like IntelliJ IDEA tend to start their own adb-server.
Even manually killing the server and running an new instance with sudo won't help here until you make your IDE kill the server itself.

exciton80... I was having a problem with your code not recursing through usercontrols. It was hitting the Grid root and throwing an error. I believe this fixes it for me:
public static object[] FindControls(this FrameworkElement f, Type childType, int maxDepth)
{
return RecursiveFindControls(f, childType, 1, maxDepth);
}
private static object[] RecursiveFindControls(object o, Type childType, int depth, int maxDepth = 0)
{
List<object> list = new List<object>();
var attrs = o.GetType().GetCustomAttributes(typeof(ContentPropertyAttribute), true);
if (attrs != null && attrs.Length > 0)
{
string childrenProperty = (attrs[0] as ContentPropertyAttribute).Name;
if (String.Equals(childrenProperty, "Content") || String.Equals(childrenProperty, "Children"))
{
var collection = o.GetType().GetProperty(childrenProperty).GetValue(o, null);
if (collection is System.Windows.Controls.UIElementCollection) // snelson 6/6/11
{
foreach (var c in (IEnumerable)collection)
{
if (c.GetType().FullName == childType.FullName)
list.Add(c);
if (maxDepth == 0 || depth < maxDepth)
list.AddRange(RecursiveFindControls(
c, childType, depth + 1, maxDepth));
}
}
else if (collection != null && collection.GetType().BaseType.Name == "Panel") // snelson 6/6/11; added because was skipping control (e.g., System.Windows.Controls.Grid)
{
if (maxDepth == 0 || depth < maxDepth)
list.AddRange(RecursiveFindControls(
collection, childType, depth + 1, maxDepth));
}
}
}
return list.ToArray();
}
Perform rotation using transform: rotate(xdeg)
and also apply overflow: hidden
to the parent component to avoid overlapping effect
.div-parent {
overflow: hidden
}
.div-child {
transform: rotate(270deg);
}
Assuming you also want to check if the item is not null
if (array.Length > 25 && array[25] != null)
{
//it exists
}
If earlier working project crashing suddenly with mentioned error you can try following solution.
This worked for me.
No, there is no way to access the element by index in JavaScript objects.
One solution to this if you have access to the source of this JSON, would be to change each element to a JSON object and stick the key inside of that object like this:
var obj = [
{"key":"set1", "data":[1, 2, 3]},
{"key":"set2", "data":[4, 5, 6, 7, 8]},
{"key":"set3", "data":[9, 10, 11, 12]}
];
You would then be able to access the elements numerically:
for(var i = 0; i < obj.length; i++) {
var k = obj[i]['key'];
var data = obj[i]['data'];
//do something with k or data...
}
Another strange behavior in my case I have a table without any primary key.EF itself creates composite primary key using all columns i.e.:
<Key>
<PropertyRef Name="ID" />
<PropertyRef Name="No" />
<PropertyRef Name="Code" />
</Key>
And whenever I do any update operation it throws this exception:
The property 'Code' is part of the object's key information and cannot be modified.
Solution: remove table from EF diagram and go to your DB add primary key on table that is creating problem and re-add table to EF diagram it's all now it will have single key i.e.
<Key>
<PropertyRef Name="ID" />
</Key>
As everyone else has said. No, you can't. However even though people have said many times over the years that you should use multiple interfaces they haven't really gone into how. Hopefully this will help.
Say you have class Foo
and class Bar
that you both want to try extending into a class FooBar
. Of course, as you said, you can't do:
public class FooBar extends Foo, Bar
People have gone into the reasons for this to some extent already. Instead, write interfaces
for both Foo
and Bar
covering all of their public methods. E.g.
public interface FooInterface {
public void methodA();
public int methodB();
//...
}
public interface BarInterface {
public int methodC(int i);
//...
}
And now make Foo
and Bar
implement the relative interfaces:
public class Foo implements FooInterface { /*...*/ }
public class Bar implements BarInterface { /*...*/ }
Now, with class FooBar
, you can implement both FooInterface
and BarInterface
while keeping a Foo
and Bar
object and just passing the methods straight through:
public class FooBar implements FooInterface, BarInterface {
Foo myFoo;
Bar myBar;
// You can have the FooBar constructor require the arguments for both
// the Foo and the Bar constructors
public FooBar(int x, int y, int z){
myFoo = new Foo(x);
myBar = new Bar(y, z);
}
// Or have the Foo and Bar objects passed right in
public FooBar(Foo newFoo, Bar newBar){
myFoo = newFoo;
myBar = newBar;
}
public void methodA(){
myFoo.methodA();
}
public int methodB(){
return myFoo.methodB();
}
public int methodC(int i){
return myBar.methodC(i);
}
//...
}
The bonus for this method, is that the FooBar
object fits the moulds of both FooInterface
and BarInterface
. That means this is perfectly fine:
FooInterface testFoo;
testFoo = new FooBar(a, b, c);
testFoo = new Foo(a);
BarInterface testBar;
testBar = new FooBar(a, b, c);
testBar = new Bar(b, c);
Hope this clarifies how to use interfaces instead of multiple extensions. Even if I am a few years late.
If you revise your regular expression like this:
drupal-6.14/(?=sites(?!/all|/default)).*
^^
...then it will match all inputs that contain drupal-6.14/
followed by sites
followed by anything other than /all
or /default
. For example:
drupal-6.14/sites/foo
drupal-6.14/sites/bar
drupal-6.14/sitesfoo42
drupal-6.14/sitesall
Changing ?=
to ?!
to match your original regex simply negates those matches:
drupal-6.14/(?!sites(?!/all|/default)).*
^^
So, this simply means that drupal-6.14/
now cannot be followed by sites
followed by anything other than /all
or /default
. So now, these inputs will satisfy the regex:
drupal-6.14/sites/all
drupal-6.14/sites/default
drupal-6.14/sites/all42
But, what may not be obvious from some of the other answers (and possibly your question) is that your regex will also permit other inputs where drupal-6.14/
is followed by anything other than sites
as well. For example:
drupal-6.14/foo
drupal-6.14/xsites
Conclusion: So, your regex basically says to include all subdirectories of drupal-6.14
except those subdirectories of sites
whose name begins with anything other than all
or default
.

You can use usort function to create own sorting rules
This code snippet is working properly
Yes it is possible depending on what css you have, you simply just declare the same thing with a different background like this
ul li {
background: none !important;
}
ul li{
background: blue !important;
}
But you have to make sure the declaration comes after the first one seeing as it is cascading.
You can also create a style tag in jQuery like this
$('head').append('<style> #an-element li { background: inherit !important;} </style>');
You cannot see any changes because it's not inheriting any background but it is overwriting the background: none;
The libs above are simple BOM detectors which of course only work if there is a BOM in the beginning of the file. Take a look at http://jchardet.sourceforge.net/ which does scans the text
The answer that accepts empty string:
/^[a-zA-Z]*$/.test('something')
the *
means 0 or more occurrences of the preceding item.
git rev-parse --abbrev-ref HEAD
The problem is caused by your #grid
having a width:1140px
.
You need to set a min-width:1140px
on the body
.
This will stop the body
from getting smaller than the #grid
. Remove width:100%
as block level elements take up the available width by default. Live example: http://jsfiddle.net/tw16/LX8R3/
html, body{
margin:0;
padding:0;
min-width: 1140px; /* this is the important part*/
}
#grid-container{
background:#f8f8f8 url(../images/grid-container-bg.gif) repeat-x top left;
}
#grid{
width:1140px;
margin:0px auto;
}
Perhaps your character array needs to be constant. Since you're initializing your array with characters from a constant string, your array needs to be constant. Try this:
#define S "ABCD"
const char a[] = { S[0], S[1], S[2], S[3] };
Uninstall Python 3.7 for Windows, and only install Python 3.6.0 then you will have no problem or receive the error message:
import tensorflow as tf ModuleNotFoundError: No module named 'tensorflow'
del
statement does not delete an instance, it merely deletes a name.When you do del i
, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.
If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.
If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.
>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst # memory is released
>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst # memory release now
Similarly, with dictionaries of arrays one can:
var dict1 = [String:[Int]]()
var dict2 = [String:[Int]]()
dict1["key"] = [1,2,3]
dict2["key"] = [4,5,6]
dict1["key"] = dict1["key"]! + dict2["key"]!
print(dict1["key"]!)
and you can iterate over dict1 and add dict2 if the "key" matches
Just use the formula
120 = (HOUR(A8)*3600+MINUTE(A8)*60+SECOND(A8))/60
Use:
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
The option you should use is iDisplayLength:
$('#adminProducts').dataTable({
'iDisplayLength': 100
});
$('#table').DataTable({
"lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});
It will Load by default all entries.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
If you want to load by default 25 not all do this.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
});

Note: It seems this is not the preferred solution because of how the extra line was being added on a Windows system. As stated in the python document:
If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.
Windows is one such platform where that makes a difference. While changing the line terminator as I described below may have fixed the problem, the problem could be avoided altogether by opening the file in binary mode. One might say this solution is more "elegent". "Fiddling" with the line terminator would have likely resulted in unportable code between systems in this case, where opening a file in binary mode on a unix system results in no effect. ie. it results in cross system compatible code.
From Python Docs:
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.
Original:
As part of optional paramaters for the csv.writer if you are getting extra blank lines you may have to change the lineterminator (info here). Example below adapated from the python page csv docs. Change it from '\n' to whatever it should be. As this is just a stab in the dark at the problem this may or may not work, but it's my best guess.
>>> import csv
>>> spamWriter = csv.writer(open('eggs.csv', 'w'), lineterminator='\n')
>>> spamWriter.writerow(['Spam'] * 5 + ['Baked Beans'])
>>> spamWriter.writerow(['Spam', 'Lovely Spam', 'Wonderful Spam'])
Nvm Nvm is a script-based node version manager. You can install it easily with a curl and bash one-liner as described in the documentation. It's also available on Homebrew.
Assuming you have successfully installed nvm. The following will install the latest version of node.
nvm install node --reinstall-packages-from=node
The last option installs all global npm packages over to your new version. This way packages like mocha and node-inspector keep working.
N
N is an npm-based node version manager. You can install it by installing first some version of node and then running npm install -g n
.
Assuming you have successfully installed n. The following will install the latest version of node.
sudo n latest
Homebrew Homebrew is one of the two popular package managers for Mac. Assuming you have previously installed node with brew install node. You can get up-to-date with formulae and upgrade to the latest Node.js version with the following.
1 brew update
2 brew upgrade node
MacPorts MacPorts is the another package manager for Mac. The following will update the local ports tree to get access to updated versions. Then it will install the latest version of Node.js. This works even if you have previous version of the package installed.
1 sudo port selfupdate
2 sudo port install nodejs-devel
You can use java.util.Arrays:
String res = Arrays.toString(array);
System.out.println(res);
Output:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
If only certain files need access to the modules in lib, just add a require statement to the files that need it. For example, if one model needs to access one module, add:
require 'mymodule'
at the top of the model.rb file.

Based on @AlecRust idea, I did an implementation of png text service.

}
Note: if you don't use the universe framework, you will need to replace this line:
$rgbColors = ConvertTool::convertHexColorToRgb($hexColor);
With this code:
$rgbColors = sscanf($hexColor, "%02x%02x%02x");
In which case your hex color must be exactly 6 chars long (don't put the hash symbol (#) in front of it).
Note: in the end, I did not use this service, because I found that the font was ugly and worse: it was not possible to select the text. But for the sake of this discussion I thought this code was worth sharing...
You want xdebug I think. Install it on the server, turn it on, pump the output through kcachegrind (for linux) or wincachegrind (for windows) and it'll show you a few pretty charts that detail the exact timings, counts and memory usage (but you'll need another extension for that).
It rocks, seriously :D
The docs show you are now able to add:
"env": {
"jest/globals": true
}
To your .eslintrc
which will add all the jest related things to your environment, eliminating the linter errors/warnings.
Division is performed using the /
operator:
result = a / b;
Modulo division is done using the %
operator:
result = a % b;
this code works on my proyect and i can select the listview item and checkbox
<?xml version="1.0" encoding="utf-8"?>

Just to add to the accepted answer, as I found it doesn't work well if the array contents are someting like:
RUN_COMMANDS=(
"command1 param1... paramN"
"command2 param1... paramN"
)
In this case, each member of the array gets split, so the array the function sees is equivalent to:
RUN_COMMANDS=(
"command1"
"param1"
...
"command2"
...
)
To get this case to work, the way I found is to pass the variable name to the function, then use eval:
function () {
eval 'COMMANDS=( "${'"$1"'[@]}" )'
for COMMAND in "${COMMANDS[@]}"; do
echo $COMMAND
done
}
function RUN_COMMANDS
Just my 2©
You can use the re
module for regexes, but regexes are probably overkill for what you want. I might try something like
z.write(article[:article.index("</html>") + 7]
This is much cleaner, and should be much faster than a regex based solution.
If for some reason you can't put your resources files in App_GlobalResources, then you can open resources files directly using ResXResourceReader or an XML Reader.
Here's sample code for using the ResXResourceReader:
public static string GetResourceString(string ResourceName, string strKey)
{
//Figure out the path to where your resource files are located.
//In this example, I'm figuring out the path to where a SharePoint feature directory is relative to a custom SharePoint layouts subdirectory.
string currentDirectory = Path.GetDirectoryName(HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ServerVariables["SCRIPT_NAME"]));
string featureDirectory = Path.GetFullPath(currentDirectory + "\\..\\..\\..\\FEATURES\\FEATURENAME\\Resources");
//Look for files containing the name
List<string> resourceFileNameList = new List<string>();
DirectoryInfo resourceDir = new DirectoryInfo(featureDirectory);
var resourceFiles = resourceDir.GetFiles();
foreach (FileInfo fi in resourceFiles)
{
if (fi.Name.Length > ResourceName.Length+1 && fi.Name.ToLower().Substring(0,ResourceName.Length + 1) == ResourceName.ToLower()+".")
{
resourceFileNameList.Add(fi.Name);
}
}
if (resourceFileNameList.Count <= 0)
{ return ""; }
//Get the current culture
string strCulture = CultureInfo.CurrentCulture.Name;
string[] cultureStrings = strCulture.Split('-');
string strLanguageString = cultureStrings[0];
string strResourceFileName="";
string strDefaultFileName = resourceFileNameList[0];
foreach (string resFileName in resourceFileNameList)
{
if (resFileName.ToLower() == ResourceName.ToLower() + ".resx")
{
strDefaultFileName = resFileName;
}
if (resFileName.ToLower() == ResourceName.ToLower() + "."+strCulture.ToLower() + ".resx")
{
strResourceFileName = resFileName;
break;
}
else if (resFileName.ToLower() == ResourceName.ToLower() + "." + strLanguageString.ToLower() + ".resx")
{
strResourceFileName = resFileName;
break;
}
}
if (strResourceFileName == "")
{
strResourceFileName = strDefaultFileName;
}
//Use resx resource reader to read the file in.
//https://msdn.microsoft.com/en-us/library/system.resources.resxresourcereader.aspx
ResXResourceReader rsxr = new ResXResourceReader(featureDirectory + "\\"+ strResourceFileName);
//IDictionaryEnumerator idenumerator = rsxr.GetEnumerator();
foreach (DictionaryEntry d in rsxr)
{
if (d.Key.ToString().ToLower() == strKey.ToLower())
{
return d.Value.ToString();
}
}
return "";
}
Sample usage:
SELECT
Getdate=GETDATE()
,SysDateTimeOffset=SYSDATETIMEOFFSET()
,SWITCHOFFSET=SWITCHOFFSET(SYSDATETIMEOFFSET(),0)
,GetutcDate=GETUTCDATE()
GO
Returns:
Getdate SysDateTimeOffset SWITCHOFFSET GetutcDate

Assuming your setup is something like: ln -s /mnt/bar ~/foo
, then you should be able to do a rm foo
with no problem. If you can't, make sure you are the owner of the foo
and have permission to write/execute the file. Removing foo
will not touch bar
, unless you do it recursively.
If you already added all libraries and it still doesn't work use:
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@drawable/ic_add"
/>
instead of:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@drawable/ic_add"
/>
And all will work fine :)
Test with a setTimeout, that worked for me and I could submit my form, refers to this answer https://stackoverflow.com/a/779785/5510314
$(document).ready(function () {
$("#btnSubmit").click(function () {
setTimeout(function () { disableButton(); }, 0);
});
function disableButton() {
$("#btnSubmit").prop('disabled', true);
}
});
With something like this:
String mDrawableName = "myappicon";
int resID = getResources().getIdentifier(mDrawableName , "drawable", getPackageName());
Couldn't get anyone of these working so will add my one just in-case it helps.
public class MyEditTextDatePicker implements OnClickListener, OnDateSetListener {
EditText _editText;
private int _day;
private int _month;
private int _birthYear;
private Context _context;
public MyEditTextDatePicker(Context context, int editTextViewID)
{
Activity act = (Activity)context;
this._editText = (EditText)act.findViewById(editTextViewID);
this._editText.setOnClickListener(this);
this._context = context;
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
_birthYear = year;
_month = monthOfYear;
_day = dayOfMonth;
updateDisplay();
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
DatePickerDialog dialog = new DatePickerDialog(_context, this,
calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}
// updates the date in the birth date EditText
private void updateDisplay() {
_editText.setText(new StringBuilder()
// Month is 0 based so add 1
.append(_day).append("/").append(_month + 1).append("/").append(_birthYear).append(" "));
}
}
Also something that isn't mentioned in the others. Make sure you put the following on EditText xml.
android:focusable="false"
Otherwise like in my case the Keyboard will keep popping up. Hope this helps someone
As others have pointed out, params
values can come from the query string of a GET request, or the form data of a POST request, but there's also a third place they can come from: The path of the URL.
As you might know, Rails uses something called routes to direct requests to their corresponding controller actions. These routes may contain segments that are extracted from the URL and put into params
. For example, if you have a route like this:
match 'products/:id', ...
Then a request to a URL like http://example.com/products/42
will set params[:id]
to 42
.

I've recently found even more interesting way to create any ValueNode
or ContainerNode
(Jackson v2.3).
ObjectNode node = JsonNodeFactory.instance.objectNode();
We can use an optional merger function also in case of same key collision. For example, If two or more persons have the same getLast() value, we can specify how to merge the values. If we not do this, we could get IllegalStateException. Here is the example to achieve this...
Map<String, Person> map =
roster
.stream()
.collect(
Collectors.toMap(p -> p.getLast(),
p -> p,
(person1, person2) -> person1+";"+person2)
);
String.prototype.replaceAll = function(character,replaceChar){
var word = this.valueOf();
while(word.indexOf(character) != -1)
word = word.replace(character,replaceChar);
return word;
}
I would recommend the following solutions:
without lib fun:
value = (value*value)/value
(The above does not actually work.)
with lib fun:
value = Math.abs(value);
In symfony 4 (probably 3.3 also, but only real-tested in 4) you can inject the Security
service via auto-wiring in the controller like this:
<?php
use Symfony\Component\Security\Core\Security;
class SomeClass
{
/**
* @var Security
*/
private $security;
public function __construct(Security $security)
{
$this->security = $security;
}
public function privatePage() : Response
{
$user = $this->security->getUser(); // null or UserInterface, if logged in
// ... do whatever you want with $user
}
}
As @ktolis says, you first have to configure your /app/config/security.yml
.
Then with
$user = $this->get('security.token_storage')->getToken()->getUser();
$user->getUsername();
should be enougth!
$user
is your User Object! You don't need to query it again.
Find out the way to set up your providers in security.yml
from Sf2 Documentation and try again.
Best luck!
You can use virtualenv
# Use this to create your temporary python "install"
# (Assuming that is the correct path to the python interpreter you want to use.)
virtualenv -p /usr/bin/python2.7 --distribute temp-python
# Type this command when you want to use your temporary python.
# While you are using your temporary python you will also have access to a temporary pip,
# which will keep all packages installed with it separate from your main python install.
# A shorter version of this command would be ". temp-python/bin/activate"
source temp-python/bin/activate
# When you no longer wish to use you temporary python type
deactivate
Enjoy!
The reliable way to do this is just like you showed $MyInvocation.MyCommand.Path
.
Using relative paths will be based on $pwd, in PowerShell, the current directory for an application, or the current working directory for a .NET API.
PowerShell v3+:
Use the automatic variable $PSScriptRoot
.
& and | provide the same outcome as the && and || operators. The difference is that they always evaluate both sides of the expression where as && and || stop evaluating if the first condition is enough to determine the outcome.
