The Tkinter library in the Python standard library is an interactive tool which you can import. Basically, you can create buttons and boxes and popups and stuff that appear as windows which you manipulate with code.
If you use Tkinter, do not use time.sleep()
, because it will muck up your program. This happened to me. Instead, use root.after()
and replace the values for however many seconds, with a milliseconds. For example, time.sleep(1)
is equivalent to root.after(1000)
in Tkinter.
Otherwise, time.sleep()
, which many answers have pointed out, which is the way to go.
Write this code :
void delay(int x)
{ int i=0,j=0;
for(i=0;i<x;i++){for(j=0;j<200000;j++){}}
}
int main()
{
int i,num;
while(1) {
delay(500);
printf("Host name");
printf("\n");}
}
I used the answer of Steve Mallory, but I am affraid the timer never or at least sometimes does not go to 86400 nor 0 (zero) sharp (MS Access 2013). So I modified the code. I changed the midnight condition to "If Timer >= 86399 Then" and added the break of the loop "Exit Do" as follows:
Public Function Pause(NumberOfSeconds As Variant)
On Error GoTo Error_GoTo
Dim PauseTime As Variant
Dim Start As Variant
Dim Elapsed As Variant
PauseTime = NumberOfSeconds
Start = Timer
Elapsed = 0
Do While Timer < Start + PauseTime
Elapsed = Elapsed + 1
If Timer >= 86399
' Crossing midnight
' PauseTime = PauseTime - Elapsed
' Start = 0
' Elapsed = 0
Exit Do
End If
DoEvents
Loop
Exit_GoTo:
On Error GoTo 0
Exit Function
Error_GoTo:
Debug.Print Err.Number, Err.Description, Erl
GoTo Exit_GoTo
End Function
Node is asynchronous by nature, and that's what's great about it, so you really shouldn't be blocking the thread, but as this seems to be for a project controlling LED's, I'll post a workaraound anyway, even if it's not a very good one and shouldn't be used (seriously).
A while loop will block the thread, so you can create your own sleep function
function sleep(time, callback) {
var stop = new Date().getTime();
while(new Date().getTime() < stop + time) {
;
}
callback();
}
to be used as
sleep(1000, function() {
// executes after one second, and blocks the thread
});
I think this is the only way to block the thread (in principle), keeping it busy in a loop, as Node doesn't have any blocking functionality built in, as it would sorta defeat the purpose of the async behaviour.
As you can see, the response is still HTTP/1.1 200 OK
. To indicate a redirect, you need to send back a 302 status code:
response.setStatus(HttpServletResponse.SC_FOUND); // SC_FOUND = 302
I still like Source Insight a lot, but I'm hesitant to recommend it anymore as I'm not sure anybody's still maintaining it. They released a very minor update back in March but haven't had a major release in years. And there seems to be no web community presence. It's a shame because I still like its auto-completion-friendly file open and symbol browsing panels (as well as syntax formatting) better than anything else I've ever used.
I test this code and
$db=new PDO('mysql:host=localhost;dbname=cwDB','root','',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$sql="select * from products ";
$stmt=$db->prepare($sql);
$stmt->execute();
while($result=$stmt->fetch(PDO::FETCH_ASSOC)){
$id=$result['id'];
}
Try this:
jsonResponse = json.loads(response.decode('utf-8'))
if you are using oracle 10g expree Edition then:
1. for loading class use
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
2. for connecting to database use
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:username/password@localhost:1521:xe");
curl --anyauth
Tells curl to figure out authentication method by itself, and use the most secure one the remote site claims to support. This is done by first doing a request and checking the response- headers, thus possibly inducing an extra network round-trip. This is used instead of setting a specific authentication method, which you can do with --basic, --digest, --ntlm, and --negotiate.
gcc is a rich and complex "orchestrating" program that calls many other programs to perform its duties. For the specific purpose of seeing where #include "goo"
and #include <zap>
will search on your system, I recommend:
$ touch a.c
$ gcc -v -E a.c
...
#include "..." search starts here:
#include <...> search starts here:
/usr/local/include
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include
/usr/include
/System/Library/Frameworks (framework directory)
/Library/Frameworks (framework directory)
End of search list.
# 1 "a.c"
This is one way to see the search lists for included files, including (if any) directories into which #include "..."
will look but #include <...>
won't. This specific list I'm showing is actually on Mac OS X (aka Darwin) but the commands I recommend will show you the search lists (as well as interesting configuration details that I've replaced with ...
here;-) on any system on which gcc runs properly.
Here I get only three specific columns from mainDataTable and use the filter
DataTable checkedParams = mainDataTable.Select("checked = true").CopyToDataTable()
.DefaultView.ToTable(false, "lagerID", "reservePeriod", "discount");
HTML 5 with Webforms 2 provides an <input type="range">
which will make the browser generate a native slider for you. Unfortunately all browsers doesn't have support for this, however google has implemented all Webforms 2 controls with js. IIRC the js is intelligent enough to know if the browser has implemented the control, and triggers only if there is no native implementation.
From my point of view it should be considered best practice to use the browsers native controls when possible.
Add the following style to your h3
elements:
word-wrap: break-word;
This will cause the long URLs in them to wrap. The default setting for word-wrap is normal
, which will wrap only at a limited set of split tokens (e.g. whitespaces, hyphens), which are not present in a URL.
input[type=text]
{
height: 15px;
line-height: 15px;
}
this is correct way to set vertical-middle position.
You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.
This is what I use to have VB
wait for process to complete before continuing.
I did not write this and do not take credit.
It was offered in some other open forum and works very well for me:
The following declarations are needed for the RunShell
subroutine:
Option Explicit
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Private Declare Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Const PROCESS_QUERY_INFORMATION = &H400
Private Const STATUS_PENDING = &H103&
'then in your subroutine where you need to shell:
RunShell (path and filename or command, as quoted text)
I have a similar situation but I want a consistent way to be able to use DateTime.Parse from the filename as well, so I went with
DateTime.Now.ToString("s").Replace(":", ".") // <-- 2016-10-25T16.50.35
When I want to parse, I can simply reverse the Replace call. This way I don't have to type in any yymmdd stuff or guess what formats DateTime.Parse allows.
Here's how you can do it with Java 8's Streams:
mySet.stream().sorted().collect(Collectors.toList());
or with a custom comparator:
mySet.stream().sorted(myComparator).collect(Collectors.toList());
If you are willing (and able) to implement partitioning, that is an effective technique for removing large quantities of data with little run-time overhead. Not cost-effective for a once-off exercise, though.
I got a very simple answer , 100% sure it works:
boolean Touched=false; // this a a global variable
public void changetouchvalue()
{
Touched=true;
}
// this code is written just before onItemSelectedListener
spinner.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
System.out.println("Real touch felt.");
changetouchvalue();
return false;
}
});
//inside your spinner.SetonItemSelectedListener , you have a function named OnItemSelected iside that function write the following code
if(Touched)
{
// the code u want to do in touch event
}
A good answer already, but there are a couple of other ways to do this:
unique(c[c%in%a[a%in%b]])
or,
tst <- c(unique(a),unique(b),unique(c))
tst <- tst[duplicated(tst)]
tst[duplicated(tst)]
You can obviously omit the unique
calls if you know that there are no repeated values within a
, b
or c
.
If you guys are generating your stylesheets with LESS/SASS and are importing Bootstrap there, I've found that overriding the @navbar-height variable lets your set the height of the navbar, which is originally defined in the variables.less file.

Something like this could be used, and still maintaining meanings of return
(to return control signals) and echo
(to return information) and logging statements (to print debug/info messages).

In here, I'm redirecting debug messages to separate file, that is watched by tail, and if there is any changes then printing the change, trap
is used to make sure that background process always ends.
This behavior can also be achieved using redirection to /dev/stderr
, But difference can be seen at the time of piping output of one command to input of other command.

If you are getting this instead:
Error: Template parse errors:
There is no directive with "exportAs" set to "ngModel"
Which was reported as a bug in github, then likely it is not a bug since you might:
[(ngModel)]]=
), ORformControlName
, with the ngModel
directive. This "has been deprecated in Angular v6 and will be removed in Angular v7", since this mixes both form strategies, making it:
seem like the actual
ngModel
directive is being used, but in fact it's an input/output property namedngModel
on the reactive form directive that simply approximates (some of) its behavior. Specifically, it allows getting/setting the value and intercepting value events. However, some ofngModel
's other features - like delaying updates withngModel
Options or exporting the directive - simply don't work (...)this pattern mixes template-driven and reactive forms strategies, which we generally don't recommend because it doesn't take advantage of the full benefits of either strategy. (...)
To update your code before v7, you'll want to decide whether to stick with reactive form directives (and get/set values using reactive forms patterns) or switch over to template-driven directives.
When you have an input like this:
<input formControlName="first" [(ngModel)]="value">
It will show a warning about mixed form strategies in the browser's console:
It looks like you're using
ngModel
on the same form field asformControlName
.
However, if you add the ngModel
as a value in a reference variable, example:
<input formControlName="first" #firstIn="ngModel" [(ngModel)]="value">
The error above is then triggered and no warning about strategy mixing is shown.
Getting the anchor point of a div/table (left) = $("#whatever").offset().left;
- ok!
Getting the anchor point of a div/table (right)
you can use the code below.
$("#whatever").width();
There are two reasons you might get this message:
%FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i
. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.table_ages <- subset(infert, select=c("age"))
summary(table_ages)
# age
# Min. :21.00
# 1st Qu.:28.00
# Median :31.00
# Mean :31.50
# 3rd Qu.:35.25
# Max. :44.00
This is probably what they're looking for. summary(...)
applied to a numeric returns the min, max, mean, median, and 25th and 75th percentile of the data.
Note that
summary(infert$age)
# Min. 1st Qu. Median Mean 3rd Qu. Max.
# 21.00 28.00 31.00 31.50 35.25 44.00
The numbers are the same but the format is different. This is because table_ages
is a data frame with one column (ages), whereas infert$age
is a numeric vector. Try typing summary(infert)
.
Wouldn't it be nice to just type debug
in front of any command to be able to debug it with gdb
on shell level?
Below it this function. It even works with following:
"$program" "$@" < <(in) 1> >(out) 2> >(two) 3> >(three)
This is a call where you cannot control anything, everything is variable, can contain spaces, linefeeds and shell metacharacters. In this example, in
, out
, two
, and three
are arbitrary other commands which consume or produce data which must not be harmed.
Following bash
function invokes gdb
nearly cleanly in such an environment [Gist]:
debug()
{
1000<&0 1001>&1 1002>&2 \
0</dev/tty 1>/dev/tty 2>&0 \
/usr/bin/gdb -q -nx -nw \
-ex 'set exec-wrapper /bin/bash -c "exec 0<&1000 1>&1001 2>&1002 \"\$@\"" exec' \
-ex r \
--args "$@";
}
Example on how to apply this: Just type debug
in front:
Before:
p=($'\n' $'I\'am\'evil' " yay ")
"b u g" "${p[@]}" < <(in) 1> >(out) 2> >(two) 3> >(three)
After:
p=($'\n' $'I\'am\'evil' " yay ")
debug "b u g" "${p[@]}" < <(in) 1> >(out) 2> >(two) 3> >(three)
That's it. Now it's an absolute no-brainer to debug with gdb
. Except for a few details or more:
gdb
does not quit automatically and hence keeps the IO redirection open until you exit gdb
. But I call this a feature.
You cannot easily pass argv0
to the program like with exec -a arg0 command args
. Following should do this trick: After exec-wrapper
change "exec
to "exec -a \"\${DEBUG_ARG0:-\$1}\"
.
There are FDs above 1000 open, which are normally closed. If this is a problem, change 0<&1000 1>&1001 2>&1002
to read 0<&1000 1>&1001 2>&1002 1000<&- 1001>&- 1002>&-
You cannot run two debuggers in parallel. There also might be issues, if some other command consumes /dev/tty
(or STDIN). To fix that, replace /dev/tty
with "${DEBUGTTY:-/dev/tty}"
. In some other TTY type tty; sleep inf
and then use the printed TTY (i. E. /dev/pts/60
) for debugging, as in DEBUGTTY=/dev/pts/60 debug command arg..
. That's the Power of Shell, get used to it!
Function explained:
1000<&0 1001>&1 1002>&2
moves away the first 3 FDs
0</dev/tty 1>/dev/tty 2>&0
restores the first 3 FDs to point to your current TTY. So you can control gdb
./usr/bin/gdb -q -nx -nw
runs gdb
invokes gdb
on shell-ex 'set exec-wrapper /bin/bash -c "exec 0<&1000 1>&1001 2>&1002 \"\$@\""
creates a startup wrapper, which restores the first 3 FDs which were saved to 1000 and above-ex r
starts the program using the exec-wrapper
--args "$@"
passes the arguments as givenWasn't that easy?
After placing the jar file in desired location, you need to add the jar file by right click on
Project --> properties --> Java Build Path --> Libraries --> Add Jar.
You can have it embedded (build action set to Resource
) as well, this is how to retrieve it from there:
private static UnmanagedMemoryStream GetResourceStream(string resName)
{
var assembly = Assembly.GetExecutingAssembly();
var strResources = assembly.GetName().Name + ".g.resources";
var rStream = assembly.GetManifestResourceStream(strResources);
var resourceReader = new ResourceReader(rStream);
var items = resourceReader.OfType<DictionaryEntry>();
var stream = items.First(x => (x.Key as string) == resName.ToLower()).Value;
return (UnmanagedMemoryStream)stream;
}
private void Button1_Click(object sender, RoutedEventArgs e)
{
string resName = "Test.txt";
var file = GetResourceStream(resName);
using (var reader = new StreamReader(file))
{
var line = reader.ReadLine();
MessageBox.Show(line);
}
}
(Some code taken from this answer by Charles)

You should run your code in a following manner in order get your output,
python file_name.py user_name
You need to create a Bundle and then use putSerializable:
List<Thumbnail> all_thumbs = new ArrayList<Thumbnail>();
all_thumbs.add(new Thumbnail(string,bitmap));
Intent intent = new Intent(getApplicationContext(),SomeClass.class);
Bundle extras = new Bundle();
extras.putSerializable("value",all_thumbs);
intent.putExtras(extras);
You can use inspect.cleandoc
to nicely format your printed SQL statement.
This works very well with your option 2.
Note: the print("-"*40)
is only to demonstrate the superflous blank lines if you do not use cleandoc.
from inspect import cleandoc
def query():
sql = """
select field1, field2, field3, field4
from table
where condition1=1
and condition2=2
"""
print("-"*40)
print(sql)
print("-"*40)
print(cleandoc(sql))
print("-"*40)
query()
Output:
----------------------------------------
select field1, field2, field3, field4
from table
where condition1=1
and condition2=2
----------------------------------------
select field1, field2, field3, field4
from table
where condition1=1
and condition2=2
----------------------------------------
From the docs:
inspect.cleandoc(doc)
Clean up indentation from docstrings that are indented to line up with blocks of code.
All leading whitespace is removed from the first line. Any leading whitespace that can be uniformly removed from the second line onwards is removed. Empty lines at the beginning and end are subsequently removed. Also, all tabs are expanded to spaces.
Simplest way is probably as follows - you basically need to construct a new array that is one element smaller, then copy the elements you want to keep to the right positions.
int n=oldArray.length-1;
String[] newArray=new String[n];
System.arraycopy(oldArray,1,newArray,0,n);
Note that if you find yourself doing this kind of operation frequently, it could be a sign that you should actually be using a different kind of data structure, e.g. a linked list. Constructing a new array every time is an O(n) operation, which could get expensive if your array is large. A linked list would give you O(1) removal of the first element.
An alternative idea is not to remove the first item at all, but just increment an integer that points to the first index that is in use. Users of the array will need to take this offset into account, but this can be an efficient approach. The Java String class actually uses this method internally when creating substrings.
This will change inputs, select etc to the old style grey not sure if you can manipulate after that:

Or you can use like this. This may be faster.

What I have done if all I want to do is see that some string was logged (as opposed to verifying exact log statements which is just too brittle) is to redirect StdOut to a buffer, do a contains, then reset StdOut:
PrintStream original = System.out;
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
System.setOut(new PrintStream(buffer));
// Do something that logs
assertTrue(buffer.toString().contains(myMessage));
System.setOut(original);
Use the where
command. The first result in the list is the one that will execute.
C:\> where notepad C:\Windows\System32\notepad.exe C:\Windows\notepad.exe
According to this blog post, where.exe
is included with Windows Server 2003 and later, so this should just work with Vista, Win 7, et al.
On Linux, the equivalent is the which
command, e.g. which ssh
.
I did a quick solution because I was short of time and it worked ok. Although I think the better option is use an Exception Filter, maybe my solution can help in the case that a simple solution is needed.
I did the following. In the controller method I returned a JsonResult with a property "Success" inside the Data:
[HttpPut]
public JsonResult UpdateEmployeeConfig(EmployeConfig employeToSave)
{
if (!ModelState.IsValid)
{
return new JsonResult
{
Data = new { ErrorMessage = "Model is not valid", Success = false },
ContentEncoding = System.Text.Encoding.UTF8,
JsonRequestBehavior = JsonRequestBehavior.DenyGet
};
}
try
{
MyDbContext db = new MyDbContext();
db.Entry(employeToSave).State = EntityState.Modified;
db.SaveChanges();
DTO.EmployeConfig user = (DTO.EmployeConfig)Session["EmployeLoggin"];
if (employeToSave.Id == user.Id)
{
user.Company = employeToSave.Company;
user.Language = employeToSave.Language;
user.Money = employeToSave.Money;
user.CostCenter = employeToSave.CostCenter;
Session["EmployeLoggin"] = user;
}
}
catch (Exception ex)
{
return new JsonResult
{
Data = new { ErrorMessage = ex.Message, Success = false },
ContentEncoding = System.Text.Encoding.UTF8,
JsonRequestBehavior = JsonRequestBehavior.DenyGet
};
}
return new JsonResult() { Data = new { Success = true }, };
}
Later in the ajax call I just asked for this property to know if I had an exception:
$.ajax({
url: 'UpdateEmployeeConfig',
type: 'PUT',
data: JSON.stringify(EmployeConfig),
contentType: "application/json;charset=utf-8",
success: function (data) {
if (data.Success) {
//This is for the example. Please do something prettier for the user, :)
alert('All was really ok');
}
else {
alert('Oups.. we had errors: ' + data.ErrorMessage);
}
},
error: function (request, status, error) {
alert('oh, errors here. The call to the server is not working.')
}
});
Hope this helps. Happy code! :P
Convert the number into a string, match the number up to the second decimal place:
function calc(theform) {_x000D_
var num = theform.original.value, rounded = theform.rounded_x000D_
var with2Decimals = num.toString().match(/^-?\d+(?:\.\d{0,2})?/)[0]_x000D_
rounded.value = with2Decimals_x000D_
}
_x000D_
<form onsubmit="return calc(this)">_x000D_
Original number: <input name="original" type="text" onkeyup="calc(form)" onchange="calc(form)" />_x000D_
<br />"Rounded" number: <input name="rounded" type="text" placeholder="readonly" readonly>_x000D_
</form>

The toFixed
method fails in some cases unlike toString
, so be very careful with it.
$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
ADD COLUMN `ping_status` INT(1) NOT NULL
AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";
I believe you need to have ADD COLUMN
and use AFTER
, not BEFORE
.
In case you want to place column at the beginning of a table, use the FIRST
statement:
$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
ADD COLUMN `ping_status` INT(1) NOT NULL
FIRST";
Here is why the original expression didn't work.
From man bash:
Brace expansion is performed before any other expansions, and any characters special to other expansions are preserved in the result. It is strictly textual. Bash does not apply any syntactic interpretation to the context of the expansion or the text between the braces.
So, brace expansion is something done early as a purely textual macro operation, before parameter expansion.
Shells are highly optimized hybrids between macro processors and more formal programming languages. In order to optimize the typical use cases, the language is made rather more complex and some limitations are accepted.
Recommendation
I would suggest sticking with Posix1 features. This means using for i in <list>; do
, if the list is already known, otherwise, use while
or seq
, as in:
#!/bin/sh
limit=4
i=1; while [ $i -le $limit ]; do
echo $i
i=$(($i + 1))
done
# Or -----------------------
for i in $(seq 1 $limit); do
echo $i
done

It doesn't sound like a good idea to use send message. I think you should try to work around the problem that the DLLs can't reference each other...
It's very easy to write that yourself, and that way you have more control over things.. As the other answers say, TypeScript is not aimed at adding runtime types or functionality.
Map:
class Map<T> {
private items: { [key: string]: T };
constructor() {
this.items = {};
}
add(key: string, value: T): void {
this.items[key] = value;
}
has(key: string): boolean {
return key in this.items;
}
get(key: string): T {
return this.items[key];
}
}
List:
class List<T> {
private items: Array<T>;
constructor() {
this.items = [];
}
size(): number {
return this.items.length;
}
add(value: T): void {
this.items.push(value);
}
get(index: number): T {
return this.items[index];
}
}
I haven't tested (or even tried to compile) this code, but it should give you a starting point.. you can of course then change what ever you want and add the functionality that YOU need...
As for your "special needs" from the List, I see no reason why to implement a linked list, since the javascript array lets you add and remove items.
Here's a modified version of the List to handle the get prev/next from the element itself:
class ListItem<T> {
private list: List<T>;
private index: number;
public value: T;
constructor(list: List<T>, value: T, index: number) {
this.list = list;
this.index = index;
this.value = value;
}
prev(): ListItem<T> {
return this.list.get(this.index - 1);
}
next(): ListItem<T> {
return this.list.get(this.index + 1);
}
}
class List<T> {
private items: Array<ListItem<T>>;
constructor() {
this.items = [];
}
size(): number {
return this.items.length;
}
add(value: T): void {
this.items.push(new ListItem<T>(this, value, this.size()));
}
get(index: number): ListItem<T> {
return this.items[index];
}
}
Here too you're looking at untested code..
Hope this helps.
Javascript has a native Map object so there's no need to create your own:
let map = new Map();
map.set("key1", "value1");
console.log(map.get("key1")); // value1
36, and the GUID will only use 0-9A-F (hexidecimal!).
12345678-1234-1234-1234-123456789012
That's 36 characters in any GUID--they are of constant length. You can read a bit more about the intricacies of GUIDs here.
You will need two more in length if you want to store the braces.
Note: 36 is the string length with the dashes in between. They are actually 16-byte numbers.
That's something controlled by your terminal, not by printf
.
printf
simply sends a \t
to the output stream (which can be a tty, a file etc), it doesn't send a number of spaces.
A local action will run once for each remote host (in parallel). If you want a unique file per host, make sure to put the inventory_hostname as part of the file name.
- local_action: copy content={{ foo_result }} dest=/path/to/destination/{{ inventory_hostname }}file
If you instead want a single file with all host's information, one way is to have a serial task (don't want to append in parallel) and then append to the file with a module (lineinfile is capable, or could pipe with a shell command)
- hosts: web_servers
serial: 1
tasks:
- local_action: lineinfile line={{ foo_result }} path=/path/to/destination/file
Alternatively, you can add a second play/role/task to the playbook which runs against only local host. Then access the variable from each of the hosts where the registration command ran inside a template Access Other Hosts Variables Docs Template Module Docs

RenderPartial takes another parameter that is simply a ViewDataDictionary. You're almost there, just call it like this:
Html.RenderPartial(

Note that this will override the default ViewData that all your other Views have by default. If you are adding anything to ViewData, it will not be in this new dictionary that you're passing to your partial view.

})
You can try this:
long diff = LocalDateTime.now().atZone(ZoneOffset.UTC).toInstant().toEpochMilli();
Add Validate Connection=true to your connection string.
Look at this blog to find more about.
DETAILS: After OracleConnection.Close() the real database connection does not terminate. The connection object is put back in connection pool. The use of connection pool is implicit by ODP.NET. If you create a new connection you get one of the pool. If this connection is "yet open" the OracleConnection.Open() method does not really creates a new connection. If the real connection is broken (for any reason) you get a failure on first select, update, insert or delete.
With Validate Connection the real connection is validated in Open() method.
There are a number of different ways... I will give you an example of one using prepared statements:
$prep = array();
foreach($insData as $k => $v ) {
$prep[':'.$k] = $v;
}
$sth = $db->prepare("INSERT INTO table ( " . implode(', ',array_keys($insData)) . ") VALUES (" . implode(', ',array_keys($prep)) . ")");
$res = $sth->execute($prep);
I'm cheating here and assuming the keys in your first array are the column names in the SQL table. I'm also assuming you have PDO available. More can be found at http://php.net/manual/en/book.pdo.php
For the accepted answer when you try to hide any view inside stack view, the constraint works not correct.
Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x618000086e50 UIView:0x7fc11c4051c0.height == 120 (active)>",
"<NSLayoutConstraint:0x610000084fb0 'UISV-hiding' UIView:0x7fc11c4051c0.height == 0 (active)>"
)
Reason is when hide the view
in stackView
it will set the height to 0 to animate it.
Solution change the constraint priority
as below.
import UIKit
class ViewController: UIViewController {
let stackView = UIStackView()
let a = UIView()
let b = UIView()
override func viewDidLoad() {
super.viewDidLoad()
a.backgroundColor = UIColor.red
a.widthAnchor.constraint(equalToConstant: 200).isActive = true
let aHeight = a.heightAnchor.constraint(equalToConstant: 120)
aHeight.isActive = true
aHeight.priority = 999
let bHeight = b.heightAnchor.constraint(equalToConstant: 120)
bHeight.isActive = true
bHeight.priority = 999
b.backgroundColor = UIColor.green
b.widthAnchor.constraint(equalToConstant: 200).isActive = true
view.addSubview(stackView)
stackView.backgroundColor = UIColor.blue
stackView.addArrangedSubview(a)
stackView.addArrangedSubview(b)
stackView.axis = .vertical
stackView.distribution = .equalSpacing
stackView.translatesAutoresizingMaskIntoConstraints = false
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.

Is there a reason you couldn't select your results and right click and choose Advanced Copy -> Advanced Copy? I'm on a Mac and this is how I always copy results to the clipboard for pasting.
Gosh, NO!!! You're asking for a world of hurt if you store formatted dates in SQL Server. Always store your dates and times and one of the SQL Server "date/time" datatypes (DATETIME, DATE, TIME, DATETIME2, whatever). Let the front end code resolve the method of display and only store formatted dates when you're building a staging table to build a file from. If you absolutely must display ISO date/time formats from SQL Server, only do it at display time. I can't emphasize enough... do NOT store formatted dates/times in SQL Server.
{Edit}. The reasons for this are many but the most obvious are that, even with a nice ISO format (which is sortable), all future date calculations and searches (search for all rows in a given month, for example) will require at least an implicit conversion (which takes extra time) and if the stored formatted date isn't the format that you currently need, you'll need to first convert it to a date and then to the format you want.
The same holds true for front end code. If you store a formatted date (which is text), it requires the same gyrations to display the local date format defined either by windows or the app.
My recommendation is to always store the date/time as a DATETIME or other temporal datatype and only format the date at display time.
One way usefull when you work with images, but can be used as workaround otherwise:

position: relative;
}
#par {
width: 100%;
background-color:red;
}
#image {
width: 100%;
visibility: hidden;
}
#myContent {
position:absolute;
}
</style>
<div id="someContainer">
<div id="par">
<div id="myContent">

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
</p>
</div>
<img src="yourImage" id="image"/>
</div>
</div>
</html>
To use replace yourImage with your image url. You use image with width / height ratio you desire.
div id="myContent" is here as example of workaround where myContent will overlay over image.
This works like: Parent div will adopt to the height of image, image height will adopt to width of parent. However image is hidden.
It is not that complicated actually. Relevant Qt widgets are in matplotlib.backends.backend_qt4agg
. FigureCanvasQTAgg
and NavigationToolbar2QT
are usually what you need. These are regular Qt widgets. You treat them as any other widget. Below is a very simple example with a Figure

from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as NavigationToolbar
from matplotlib.figure import Figure
import random
class Window(QtGui.QDialog):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
# a figure instance to plot on
self.figure = Figure()
# this is the Canvas Widget that displays the `figure`
# it takes the `figure` instance as a parameter to __init__
self.canvas = FigureCanvas(self.figure)
# this is the Navigation widget
# it takes the Canvas widget and a parent
self.toolbar = NavigationToolbar(self.canvas, self)
# Just some button connected to `plot` method
self.button = QtGui.QPushButton('Plot')
self.button.clicked.connect(self.plot)
# set the layout
layout = QtGui.QVBoxLayout()
layout.addWidget(self.toolbar)
layout.addWidget(self.canvas)
layout.addWidget(self.button)
self.setLayout(layout)
def plot(self):
''' plot some random stuff '''
# random data
data = [random.random() for i in range(10)]
# create an axis
ax = self.figure.add_subplot(111)
# discards the old graph
ax.clear()
# plot data
ax.plot(data, '*-')
# refresh canvas
self.canvas.draw()
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
main = Window()
main.show()
sys.exit(app.exec_())
Edit:
Updated to reflect comments and API changes.
NavigationToolbar2QTAgg

A ReentrantLock is unstructured, unlike synchronized
constructs -- i.e. you don't need to use a block structure for locking and can even hold a lock across methods. An example:
private ReentrantLock lock;
public void foo() {
...
lock.lock();
...
}
public void bar() {
...
lock.unlock();
...
}
Such flow is impossible to represent via a single monitor in a synchronized
construct.
Aside from that, ReentrantLock
supports lock polling and interruptible lock waits that support time-out. ReentrantLock
also has support for configurable fairness policy, allowing more flexible thread scheduling.
The constructor for this class accepts an optional fairness parameter. When set
true
, under contention, locks favor granting access to the longest-waiting thread. Otherwise this lock does not guarantee any particular access order. Programs using fair locks accessed by many threads may display lower overall throughput (i.e., are slower; often much slower) than those using the default setting, but have smaller variances in times to obtain locks and guarantee lack of starvation. Note however, that fairness of locks does not guarantee fairness of thread scheduling. Thus, one of many threads using a fair lock may obtain it multiple times in succession while other active threads are not progressing and not currently holding the lock. Also note that the untimedtryLock
method does not honor the fairness setting. It will succeed if the lock is available even if other threads are waiting.
ReentrantLock
may also be more scalable, performing much better under higher contention. You can read more about this here.
This claim has been contested, however; see the following comment:
In the reentrant lock test, a new lock is created each time, thus there is no exclusive locking and the resulting data is invalid. Also, the IBM link offers no source code for the underlying benchmark so its impossible to characterize whether the test was even conducted correctly.
When should you use ReentrantLock
s? According to that developerWorks article...
The answer is pretty simple -- use it when you actually need something it provides that
synchronized
doesn't, like timed lock waits, interruptible lock waits, non-block-structured locks, multiple condition variables, or lock polling.ReentrantLock
also has scalability benefits, and you should use it if you actually have a situation that exhibits high contention, but remember that the vast majority ofsynchronized
blocks hardly ever exhibit any contention, let alone high contention. I would advise developing with synchronization until synchronization has proven to be inadequate, rather than simply assuming "the performance will be better" if you useReentrantLock
. Remember, these are advanced tools for advanced users. (And truly advanced users tend to prefer the simplest tools they can find until they're convinced the simple tools are inadequate.) As always, make it right first, and then worry about whether or not you have to make it faster.
One final aspect that's gonna become more relevant in the near future has to do with Java 15 and Project Loom. In the (new) world of virtual threads, the underlying scheduler would be able to work much better with ReentrantLock
than it's able to do with synchronized
, that's true at least in the initial Java 15 release but may be optimized later.
In the current Loom implementation, a virtual thread can be pinned in two situations: when there is a native frame on the stack — when Java code calls into native code (JNI) that then calls back into Java — and when inside a
synchronized
block or method. In those cases, blocking the virtual thread will block the physical thread that carries it. Once the native call completes or the monitor released (thesynchronized
block/method is exited) the thread is unpinned.
If you have a common I/O operation guarded by a
synchronized
, replace the monitor with aReentrantLock
to let your application benefit fully from Loom’s scalability boost even before we fix pinning by monitors (or, better yet, use the higher-performanceStampedLock
if you can).
JVM, JRE, JDK - these are all the backbone of Java language. Each component work separately. JDK and JRE physically exist but JVM is an abstract machine that means it does not physically exist.
JVM is the subsystem of JDK and JRE which is used to check the intermediate code known as "bytecode". It first loads the "class file" (having .c extension) generated by the Java compiler (javac) through JVM subsystem classloader and classified memory location (class area, stack, heap and pc registers) according to their use. Then it checks all the bytecode to ensure that it is returned in Java and all memory accessibility access by the network. The interpreter's work starts after that where it checks the whole program line by line. The results are finally shown in the console/browser/application through JRE (Java Runtime Environment) which runtime facilities.
JRE is also a subsystem of JDK which provides runtime facilities like JVM, classes, executable files like .jar file, etc.
JDK stands for Java Development Kit. It contains all necessary components used in Java programming such as class, method, swing, AWT, package, Java (interpreter), javac (compiler), appletviewer (applet application viewer), etc. To conclude, it contains every file required for developing applications, whether standalone or web-based.
For me CSS solutions didn't work. But setting the width programmatically does the job. On iframe load set the width programmatically:

Simply call list
on the generator.
lst = list(gen)
lst
Be aware that this affects the generator which will not return any further items.
You also cannot directly call list
in IPython, as it conflicts with a command for listing lines of code.
Tested on this file:
def gen():
yield 1
yield 2
yield 3
yield 4
yield 5
import ipdb
ipdb.set_trace()
g1 = gen()
text = "aha" + "bebe"
mylst = range(10, 20)
which when run:
$ python code.py
> /home/javl/sandbox/so/debug/code.py(10)<module>()
9
---> 10 g1 = gen()
11
ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
11

Exiting Debugger.
There are debugger commands p

that will print

9
---> 10 g1 = gen()
11
ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
11
---> 12 text = "aha" + "bebe"
13
ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c
There is also an exec
command, called by prefixing your expression with !
, which forces debugger to take your expression as Python one.
ipdb> !list(g1)
[]
For more details see help p
, help pp
and help exec
when in debugger.
ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the

model.paramOne="${model.paramOne}";
model.paramTwo="${model.paramTwo}";
model.paramThree="${model.paramThree}";
</script>
Note that you can't asssign using var model = ${model}
as it will assign a java object reference. So to access this in external JS:
$(document).ready(function() {
alert(model.paramOne);
});
There's no difference, ==
is a synonym for =
(for the C/C++ people, I assume). See here, for example.
You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.
You can call a stored procedure using the following syntax:
$result = mysql_query('CALL getNodeChildren(2)');
I had missed another tiny detail: I forgot the brackets "(100)" behind NVARCHAR.
I tried this command to display the list of files in the directory.
dir /s /b > List.txt
In the file it displays the list below.
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppMgr.dll
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppSDK.dll
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Plantronics
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\SennheiserJabberPlugin.dll
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco\lucpcisco.dll
What is want to do is only to display sub-directory not the full directory path.
Just like this:
Cisco Jabber\XmppMgr.dll Cisco Jabber\XmppSDK.dll
Cisco Jabber\accessories\JabraJabberPlugin.dll
Cisco Jabber\accessories\Logitech
Cisco Jabber\accessories\Plantronics
Cisco Jabber\accessories\SennheiserJabberPlugin.dll
It doesn't seem like you can access this in browser. The search input is a Webkit HTML wrapper for the Cocoa NSSearchField. The cancel button seems to be contained within the browser client code with no external reference available from the wrapper.
Sources:
Looks like you'll have to figure it out through mouse position on click with something like:
$('input[type=search]').bind('click', function(e) {
var $earch = $(this);
var offset = $earch.offset();
if (e.pageX > offset.left + $earch.width() - 16) { // X button 16px wide?
// your code here
}
});
With Angular CLI, you can use the following command:
ng build --prod
It generates a dist folder with all you need to deploy the application.
If you have no practice with web servers, I recommend you to use Angular to Cloud. You just need to compress the dist folder as zip file and upload it in the platform.
always use 'r' to get a raw string when you want to avoid escape.
test_file=open(r'c:\Python27\test.txt','r')
shuffle(names)
is an in-place operation. Drop the assignment.
This function returns None
and that's why you have the error:
TypeError: object of type 'NoneType' has no len()
It is easier to break the quicksort into three sections doing this
It is only slightly more inefficent than one long function but is alot easier to understand.
Code follows:
/* This selects what the data type in the array to be sorted is */
#define DATATYPE long
/* This is the swap function .. your job is to swap data in x & y .. how depends on
data type .. the example works for normal numerical data types .. like long I chose
above */
void swap (DATATYPE *x, DATATYPE *y){
DATATYPE Temp;
Temp = *x; // Hold current x value
*x = *y; // Transfer y to x
*y = Temp; // Set y to the held old x value
};
/* This is the partition code */
int partition (DATATYPE list[], int l, int h){
int i;
int p; // pivot element index
int firsthigh; // divider position for pivot element
// Random pivot example shown for median p = (l+h)/2 would be used
p = l + (short)(rand() % (int)(h - l + 1)); // Random partition point
swap(&list[p], &list[h]); // Swap the values
firsthigh = l; // Hold first high value
for (i = l; i < h; i++)
if(list[i] < list[h]) { // Value at i is less than h
swap(&list[i], &list[firsthigh]); // So swap the value
firsthigh++; // Incement first high
}
swap(&list[h], &list[firsthigh]); // Swap h and first high values
return(firsthigh); // Return first high
};
/* Finally the body sort */
void quicksort(DATATYPE list[], int l, int h){
int p; // index of partition
if ((h - l) > 0) {
p = partition(list, l, h); // Partition list
quicksort(list, l, p - 1); // Sort lower partion
quicksort(list, p + 1, h); // Sort upper partition
};
};
In Android Studio, above Version 3.6, There is a new location to toggle Gradle's offline mode To enable or disable Gradle's offline mode.
To enable or disable Gradle's offline mode, select View > Tool Windows > Gradle
from the menu. In the top bar of the Gradle window, click Toggle Offline Mode
(near settings icon).
It's a little bit confusing on the icon, anyway offline mode is enabled when the toggle button is highlighted. :)
Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount()
in a React class.
For you edit, you may want to try something like this:
class Component extends React.Component {
constructor(props) {
super(props);
this.onAddBucket = this.onAddBucket.bind(this);
}
componentWillMount() {
this.setState({
buckets: {},
})
}
componentDidMount() {
this.onAddBucket();
}
onAddBucket() {
let self = this;
let getToken = localStorage.getItem('myToken');
var apiBaseUrl = "...";
let input = {
"name" : this.state.fields["bucket_name"]
}
axios.defaults.headers.common['Authorization'] = getToken;
axios.post(apiBaseUrl+'...',input)
.then(function (response) {
if (response.data.status == 200) {
this.setState({
buckets: this.state.buckets.concat(response.data.buckets),
});
} else {
alert(response.data.message);
}
})
.catch(function (error) {
console.log(error);
});
}
render() {
return (
{this.state.bucket}
);
}
}
When onMeasure
is called the view gets its measured width/height. After this, you can call layout.getMeasuredHeight()
.
Pretty good documentation is provided on the MongoDB website
Install MongoDB
Determine which MongoDB build you need.
There are three builds of MongoDB for Windows:
MongoDB for Windows Server 2008 R2 edition (i.e. 2008R2) runs only on Windows Server 2008 R2, Windows 7 64-bit, and newer versions of Windows. This build takes advantage of recent enhancements to the Windows Platform and cannot operate on older versions of Windows.
MongoDB for Windows 64-bit runs on any 64-bit version of Windows newer than Windows XP, including Windows Server 2008 R2 and Windows 7 64-bit.
MongoDB for Windows 32-bit runs on any 32-bit version of Windows newer than Windows XP. 32-bit versions of MongoDB are only intended for older systems and for use in testing and development systems. 32-bit versions of MongoDB only support databases smaller than 2GB.
To find which version of Windows you are running, enter the following command in the Command Prompt:
wmic os get osarchitecture
Download MongoDB for Windows.
Download the latest production release of MongoDB from the MongoDB downloads page. Ensure you download the correct version of MongoDB for your Windows system. The 64-bit versions of MongoDB does not work with 32-bit Windows.
Install the downloaded file.
In Windows Explorer, locate the downloaded MongoDB msi file, which typically is located in the default Downloads folder. Double-click the msi file. A set of screens will appear to guide you through the installation process.
Move the MongoDB folder to another location (optional).
To move the MongoDB folder, you must issue the move command as an Administrator. For example, to move the folder to C:\mongodb:
Select Start Menu > All Programs > Accessories.
Right-click Command Prompt and select Run as Administrator from the popup menu.
Issue the following commands:
cd \ move C:\mongodb-win32-* C:\mongodb
MongoDB is self-contained and does not have any other system dependencies. You can run MongoDB from any folder you choose. You may install MongoDB in any folder (e.g.
D:\test\mongodb
)Run MongoDB
Warning:
Do not make
mongod.exe
visible on public networks without running in “Secure Mode” with the auth setting. MongoDB is designed to be run in trusted environments, and the database does not enable “Secure Mode” by default.
Set up the MongoDB environment.
MongoDB requires a data directory to store all data. MongoDB’s default data directory path is \data\db. Create this folder using the following commands from a Command Prompt:
md \data\db
You can specify an alternate path for data files using the
--dbpath
option tomongod.exe
, for example:C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
If your path includes spaces, enclose the entire path in double quotes, for example:
C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
Start MongoDB.
To start MongoDB, run
mongod.exe
. For example, from the Command Prompt:C:\Program Files\MongoDB\bin\mongod.exe
This starts the main MongoDB database process. The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.
Depending on the security level of your system, Windows may pop up a Security Alert dialog box about blocking “some features” of C:\Program Files\MongoDB\bin\mongod.exe from communicating on networks. All users should select Private Networks, such as my home or work network and click Allow access. For additional information on security and MongoDB, please see the Security Documentation.
Connect to MongoDB.
To connect to MongoDB through the mongo.exe shell, open another Command Prompt. When connecting, specify the data directory if necessary. This step provides several example connection commands.
If your MongoDB installation uses the default data directory, connect without specifying the data directory:
C:\mongodb\bin\mongo.exe
If you installation uses a different data directory, specify the directory when connecting, as in this example:
C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
If your path includes spaces, enclose the entire path in double quotes. For example:
C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
If you want to develop applications using .NET, see the documentation of C# and MongoDB for more information.
Begin using MongoDB.
To begin using MongoDB, see Getting Started with MongoDB. Also consider the Production Notes document before deploying MongoDB in a production environment.
Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.
Configure a Windows Service for MongoDB
Note:
There is a known issue for MongoDB 2.6.0, SERVER-13515, which prevents the use of the instructions in this section. For MongoDB 2.6.0, use Manually Create a Windows Service for MongoDB to create a Windows Service for MongoDB instead.
Configure directories and files.
Create a configuration file and a directory path for MongoDB log output (logpath):
Create a specific directory for MongoDB log files:
md "C:\Program Files\MongoDB\log"
In the Command Prompt, create a configuration file for the logpath option for MongoDB:
echo logpath=C:\Program Files\MongoDB\log\mongo.log > "C:\Program Files\MongoDB\mongod.cfg"
Run the MongoDB service.
Run all of the following commands in Command Prompt with “Administrative Privileges:”
Install the MongoDB service. For
--install
to succeed, you must specify the logpath run-time option."C:\Program Files\MongoDB\bin\mongod.exe" --config "C:\Program Files\MongoDB\mongod.cfg" --install
Modify the path to the mongod.cfg file as needed.
To use an alternate dbpath, specify the path in the configuration file (e.g. C:\Program Files\MongoDB\mongod.cfg) or on the command line with the --dbpath option.
If the dbpath directory does not exist, mongod.exe will not start. The default value for dbpath is
\data\db
.If needed, you can install services for multiple instances of mongod.exe or mongos.exe. Install each service with a unique
--serviceName
and--serviceDisplayName
. Use multiple instances only when sufficient system resources exist and your system design requires it.Stop or remove the MongoDB service as needed.
To stop the MongoDB service use the following command:
net stop MongoDB
To remove the MongoDB service use the following command:
"C:\Program Files\MongoDB\bin\mongod.exe" --remove
Manually Create a Windows Service for MongoDB
The following procedure assumes you have installed MongoDB using the MSI installer, with the default path C:\Program Files\MongoDB 2.6 Standard.
If you have installed in an alternative directory, you will need to adjust the paths as appropriate.
Open an Administrator command prompt.
Windows 7 / Vista / Server 2008 (and R2)
Press Win + R, then type
cmd
, then press Ctrl + Shift + Enter.Windows 8
Press Win + X, then press A.
Execute the remaining steps from the Administrator command prompt.
Create directories.
Create directories for your database and log files:
mkdir c:\data\db mkdir c:\data\log
Create a configuration file.
Create a configuration file. This file can include any of the configuration options for mongod, but must include a valid setting for logpath:
The following creates a configuration file, specifying both the logpath and the dbpath settings in the configuration file:
echo logpath=c:\data\log\mongod.log> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg" echo dbpath=c:\data\db>> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg"
Create the MongoDB service.
Create the MongoDB service.
sc.exe create MongoDB binPath= "\"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe\" --service --config=\"C:\Program Files\MongoDB 2.6 Standard\mongod.cfg\"" DisplayName= "MongoDB 2.6 Standard" start= "auto"
sc.exe
requires a space between “=
” and the configuration values (eg “binPath=
”), and a “” to escape double quotes.If successfully created, the following log message will display:
[SC] CreateService SUCCESS
Start the MongoDB service.
net start MongoDB
Stop or remove the MongoDB service as needed.
To stop the MongoDB service, use the following command:
net stop MongoDB
To remove the MongoDB service, first stop the service and then run the following command:
sc.exe delete MongoDB
You can call the scp
bash command (it copies files over SSH) with subprocess.run
:
import subprocess
subprocess.run(["scp", FILE, "USER@SERVER:PATH"])
#e.g. subprocess.run(["scp", "foo.bar", "[email protected]:/path/to/foo.bar"])
If you're creating the file that you want to send in the same Python program, you'll want to call subprocess.run
command outside the with
block you're using to open the file (or call .close()
on the file first if you're not using a with
block), so you know it's flushed to disk from Python.
You need to generate (on the source machine) and install (on the destination machine) an ssh key beforehand so that the scp automatically gets authenticated with your public ssh key (in other words, so your script doesn't ask for a password).

I'm a fan of gitk
's graphical UI to visualize git repos. You can view the last item stashed with:
gitk stash
You can also use view any of your stashed changes (as listed by git stash list
). For example:
gitk stash@{2}
In the below screenshot, you can see the stash as a commit in the upper-left, when and where it came from in commit history, the list of files modified on the bottom right, and the line-by-line diff in the lower-left. All while the stash is still tucked away.
Requires Newtonsoft Json.Net
A little late, but I came up with this. It gives you just the keys and then you can use those on the dynamic:
public List<string> GetPropertyKeysForDynamic(dynamic dynamicToGetPropertiesFor)
{
JObject attributesAsJObject = dynamicToGetPropertiesFor;
Dictionary<string, object> values = attributesAsJObject.ToObject<Dictionary<string, object>>();
List<string> toReturn = new List<string>();
foreach (string key in values.Keys)
{
toReturn.Add(key);
}
return toReturn;
}
Then you simply foreach like this:
foreach(string propertyName in GetPropertyKeysForDynamic(dynamicToGetPropertiesFor))
{
dynamic/object/string propertyValue = dynamicToGetPropertiesFor[propertyName];
// And
dynamicToGetPropertiesFor[propertyName] = "Your Value"; // Or an object value
}
Choosing to get the value as a string or some other object, or do another dynamic and use the lookup again.

In C++11 you can. A note beforehand: Don't new
the array, there's no need for that.
First, string[] strArray
is a syntax error, that should either be string* strArray
or string strArray[]
. And I assume that it's just for the sake of the example that you don't pass any size parameter.
#include <string>
void foo(std::string* strArray, unsigned size){
// do stuff...
}
template<class T>
using alias = T;
int main(){
foo(alias<std::string[]>{"hi", "there"}, 2);
}
Note that it would be better if you didn't need to pass the array size as an extra parameter, and thankfully there is a way: Templates!
template<unsigned N>
void foo(int const (&arr)[N]){
// ...
}
Note that this will only match stack arrays, like int x[5] = ...
. Or temporary ones, created by the use of alias
above.
int main(){
foo(alias<int[]>{1, 2, 3});
}
There is no problem to do sudo python setup.py install, if you're sure it's what you want to do.
The difference is that it will use the site-packages directory of your OS as a destination for .py files to be copied.
so, if you want pip to be accessible os wide, that's probably the way to go. I do not say that others way are bad, but this is probably fair enough.
Have you tried adding the verbose (-v

The best answer I have ever seen is How to run 32-bit applications on Ubuntu 64-bit?
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo ./adb
You can intercept the key press events, cancel the lowercase ones, and append their uppercase versions to the input:
window.onload = function () {
var input = document.getElementById("test");
input.onkeypress = function () {
// So that things work both on Firefox and Internet Explorer.
var evt = arguments[0] || event;
var char = String.fromCharCode(evt.which || evt.keyCode);
// Is it a lowercase character?
if (/[a-z]/.test(char)) {
// Append its uppercase version
input.value += char.toUpperCase();
// Cancel the original event
evt.cancelBubble = true;
return false;
}
}
};
This works in both Firefox and Internet Explorer. You can see it in action here.
Outside of using pl/pgsql or other pl/* language as suggested, this is the only other possibility I could think of.

Instanceof works if you don't depend on specific classes, but also keep in mind that you can have nulls in the list, so obj.getClass() will fail, but instanceof always returns false on null.
This has nothing to do with a malformed upload. The HTTP error clearly specifies 401 unauthorized, and tells you the CSRF token is invalid. Try sending a valid CSRF token with the upload.

I'd suggest you do two things:
>>
in your shell script to append contents to particular file. The filename can be fixed or using some pattern.The solution provided by @dex worked for me. But I want to add something else that also worked for me: Use
let UserSchema = new Schema({
username: {
type: String
},
events: [{
type: ObjectId,
ref: 'Event' // Reference to some EventSchema
}]
})
if what you want to create is an Array reference. But if what you want is an Object reference, which is what I think you might be looking for anyway, remove the brackets from the value prop, like this:
let UserSchema = new Schema({
username: {
type: String
},
events: {
type: ObjectId,
ref: 'Event' // Reference to some EventSchema
}
})
Look at the 2 snippets well. In the second case, the value prop of key events does not have brackets over the object def.
select right(convert(varchar(20),getdate(),100),7)
All of the above solutions recognize a string like "http://www.google.com/path,www.yahoo.com/path" as valid. This solution always works as it should

You can try this:-

SET @PreviousStartdate = '01/01/2010'
There are a few ways of passing data around to different routes. The most correct answer is, of course, query strings. You'll need to ensure that the values are properly encodeURIComponent and decodeURIComponent.
app.get('/category', function(req, res) {
var string = encodeURIComponent('something that would break');
res.redirect('/?valid=' + string);
});
You can snag that in your other route by getting the parameters sent by using req.query
.
app.get('/', function(req, res) {
var passedVariable = req.query.valid;
// Do something with variable
});
For more dynamic way you can use the url
core module to generate the query string for you:
const url = require('url');
app.get('/category', function(req, res) {
res.redirect(url.format({
pathname:"/",
query: {
"a": 1,
"b": 2,
"valid":"your string here"
}
}));
});
So if you want to redirect all req query string variables you can simply do
res.redirect(url.format({
pathname:"/",
query:req.query,
});
});
And if you are using Node >= 7.x you can also use the querystring
core module
const querystring = require('querystring');
app.get('/category', function(req, res) {
const query = querystring.stringify({
"a": 1,
"b": 2,
"valid":"your string here"
});
res.redirect('/?' + query);
});
Another way of doing it is by setting something up in the session. You can read how to set it up here, but to set and access variables is something like this:
app.get('/category', function(req, res) {
req.session.valid = true;
res.redirect('/');
});
And later on after the redirect...
app.get('/', function(req, res) {
var passedVariable = req.session.valid;
req.session.valid = null; // resets session variable
// Do something
});
There is also the option of using an old feature of Express, req.flash
. Doing so in newer versions of Express will require you to use another library. Essentially it allows you to set up variables that will show up and reset the next time you go to a page. It's handy for showing errors to users, but again it's been removed by default. EDIT: Found a library that adds this functionality.
Hopefully that will give you a general idea how to pass information around in an Express application.
For Windows:
mvn deploy:deploy-file -DgroupId=joda-time -DartifactId=joda-time -Dversion=2.7 -Dpackaging=jar -Dfile=joda-time-2.7.jar
-DgeneratePom=true -DrepositoryId=[Your ID] -Durl=[YourURL]
The sender is the control that the action is for (say OnClick, it's the button).
The EventArgs are arguments that the implementor of this event may find useful. With OnClick it contains nothing good, but in some events, like say in a GridView 'SelectedIndexChanged', it will contain the new index, or some other useful data.
What Chris is saying is you can do this:
protected void someButton_Click (object sender, EventArgs ea)
{
Button someButton = sender as Button;
if(someButton != null)
{
someButton.Text = "I was clicked!";
}
}
Having some experience of this, you can indeed use C++ code for your "core" code, but you have to use objective-C for anything iPhone specific.
Don't try to force Objective-C to act like C++. At first it will seem to you this is possible, but the resulting code really won't work well with Cocoa, and you will get very confused as to what is going on. Take the time to learn properly, without any C++ around, how to build GUIs and iPhone applications, then link in your C++ base.
Seems like the accepted answer does not work anymore. I found the correct method from another post: https://stackoverflow.com/a/46811403/6368026
Now you should use:
http://www.youtube.com/embed/videoseries?list=USERID And the USERID is your youtube user id with 'UU' appended.
For example, if your user id is TlQ5niAIDsLdEHpQKQsupg then you should put UUTlQ5niAIDsLdEHpQKQsupg. If you only have the channel id (which you can find in your channel URL) then just replace the first two characters (UC) with UU.
So in the end you would have an URL like this:
http://www.youtube.com/embed/videoseries?list=UUTlQ5niAIDsLdEHpQKQsupg
Follow these steps:
cd..

cd Program Files\Python38\Scripts

folder.pip install packagename.whl
You can write your python version instead of "38"
In an SQL query, if the inner query executes for every row of the outer query. If the inner query is executed for once and the result is consumed by the outer query, then it is called as non co-related query.
Create file .flaskenv
in the project root directory.
The parameters in this file are typically:
FLASK_APP=app.py
FLASK_ENV=development
FLASK_RUN_HOST=[dev-host-ip]
FLASK_RUN_PORT=5000
If you have a virtual environment, activate it and do a pip install python-dotenv
.
This package is going to use the .flaskenv
file, and declarations inside it will be automatically imported across terminal sessions.
Then you can do flask run

h:commandButton vs h:button
What’s the difference between h:commandButton|h:commandLink and h:button|h:link ?
The latter two components were introduced in 2.0
to enable bookmarkable
JSF pages, when used in concert with the View Parameters feature.
There are 3 main differences between h:button|h:link and h:commandButton|h:commandLink.
First,
h:button|h:link
causes the browser to issue an HTTP GET request, whileh:commandButton|h:commandLink
does a form POST. This means that any components in the page that have values entered by the user, such as text fields, checkboxes, etc., will not automatically be submitted to the server when usingh:button|h:link
. To cause values to be submitted withh:button|h:link
, extra action has to be taken, using the “View Parameters” feature.The second main difference between the two kinds of components is that
h:button|h:link
has an outcome attribute to describe where to go next whileh:commandButton|h:commandLink
uses an action attribute for this purpose. This is because the former does not result in an ActionEvent in the event system, while the latter does.Finally, and most important to the complete understanding of this feature, the
h:button|h:link
components cause the navigation system to be asked to derive the outcome during the rendering of the page, and the answer to this question is encoded in the markup of the page. In contrast, theh:commandButton|h:commandLink
components cause the navigation system to be asked to derive the outcome on the POSTBACK from the page. This is a difference in timing. Rendering always happens before POSTBACK.
When working with async functions or observables provided by 3rd party libraries, for example Cloud firestore, I've found functions the waitFor
method shown below (TypeScript, but you get the idea...) to be helpful when you need to wait on some process to complete, but you don't want to have to embed callbacks within callbacks within callbacks nor risk an infinite loop.
This method is sort of similar to a while (!condition)
sleep loop, but
yields asynchronously and performs a test on the completion condition at regular intervals till true or timeout.
export const sleep = (ms: number) => {
return new Promise(resolve => setTimeout(resolve, ms))
}
/**
* Wait until the condition tested in a function returns true, or until
* a timeout is exceeded.
* @param interval The frenequency with which the boolean function contained in condition is called.
* @param timeout The maximum time to allow for booleanFunction to return true
* @param booleanFunction: A completion function to evaluate after each interval. waitFor will return true as soon as the completion function returns true.
*/
export const waitFor = async function (interval: number, timeout: number,
booleanFunction: Function): Promise<boolean> {
let elapsed = 1;
if (booleanFunction()) return true;
while (elapsed < timeout) {
elapsed += interval;
await sleep(interval);
if (booleanFunction()) {
return true;
}
}
return false;
}
The say you have a long running process on your backend you want to complete before some other task is undertaken. For example if you have a function that totals a list of accounts, but you want to refresh the accounts from the backend before you calculate, you can do something like this:
async recalcAccountTotals() : number {
this.accountService.refresh(); //start the async process.
if (this.accounts.dirty) {
let updateResult = await waitFor(100,2000,()=> {return !(this.accounts.dirty)})
}
if(!updateResult) {
console.error("Account refresh timed out, recalc aborted");
return NaN;
}
return ... //calculate the account total.
}
all of these steered me to the correct result, but I wound up doing
DateTime.now.mjd - DateTime.parse("01-01-1995").mjd

I implemented a solution using a function that filters a combobox (<select>
) based on custom data- attributes. This solution supports:
<option>
to show when the filter would leave the select empty.<option>
elements without the data-filter attribute are left untouched.Tested with jQuery 2.1.4 and Firefox, Chrome, Safari and IE 10+.
This is the example HTML:
<select id="myCombobox">
<option data-filter="1" value="AAA">Option 1</option>
<option data-filter="1" value="BBB">Option 2</option>
<option data-filter="2" value="CCC">Option 3</option>
<option data-filter="2" value="DDD">Option 4</option>
<option data-filter="3" value="EEE">Option 5</option>
<option data-filter="3" value="FFF">Option 6</option>
<option data-filter-emptyvalue disabled>No Options</option>
</select>
The jQuery code for the filtering:
function filterCombobox(selectObject, filterValue, autoSelect) {
var fullData = selectObject.data("filterdata-values");
var emptyValue = selectObject.data("filterdata-emptyvalue");
// Initialize if first time.
if (!fullData) {
fullData = selectObject.find("option[data-filter]").detach();
selectObject.data("filterdata-values", fullData);
emptyValue = selectObject.find("option[data-filter-emptyvalue]").detach();
selectObject.data("filterdata-emptyvalue", emptyValue);
selectObject.addClass("filtered");
}
else {
// Remove elements from DOM
selectObject.find("option[data-filter]").remove();
selectObject.find("option[data-filter-emptyvalue]").remove();
}
// Get filtered elements.
var toEnable = fullData.filter("option[data-filter][data-filter='" + filterValue + "']");
// Attach elements to DOM
selectObject.append(toEnable);
// If toEnable is empty, show empty option.
if (toEnable.length == 0) {
selectObject.append(emptyValue);
}
// Select First Occurrence
if (autoSelect) {
var obj = selectObject.find("option[selected]");
selectObject.val(obj.length == 0 ? toEnable.val() : obj.val());
}
}
To use it, you just call the function with the value you want to keep.
filterCombobox($("#myCombobox"), 2, true);
Then the resulting select will be:
<select id="myCombobox">
<option data-filter="2" value="CCC">Option 3</option>
<option data-filter="2" value="DDD">Option 4</option>
</select>
The original elements are stored by the data() function, so subsequent calls will add and remove the correct elements.
I had an identical problem, which I solved by restarting my Python editor and shell. I had installed pywin32
but the new modules were not picked up until the restarts.
If you've already done that, do a search in your Python installation for win32api
and you should find win32api.pyd
under ${PYTHON_HOME}\Lib\site-packages\win32
.
According to the documentation for 3.4, It is preferred to use attributes with attr()
method.
$('<div></div>').attr(
{
id: 'some dynanmic|static id',
"class": 'some dynanmic|static class'
}
).click(function() {
$( "span", this ).addClass( "bar" ); // example from the docs
});
I write these 2 functions to make my life easier:
function scrollToTop(elem, parent, speed) {
var scrollOffset = parent.scrollTop() + elem.offset().top;
parent.animate({scrollTop:scrollOffset}, speed);
// parent.scrollTop(scrollOffset, speed);
}
function scrollToCenter(elem, parent, speed) {
var elOffset = elem.offset().top;
var elHeight = elem.height();
var parentViewTop = parent.offset().top;
var parentHeight = parent.innerHeight();
var offset;
if (elHeight >= parentHeight) {
offset = elOffset;
} else {
margin = (parentHeight - elHeight)/2;
offset = elOffset - margin;
}
var scrollOffset = parent.scrollTop() + offset - parentViewTop;
parent.animate({scrollTop:scrollOffset}, speed);
// parent.scrollTop(scrollOffset, speed);
}
And use them:
scrollToTop($innerListItem, $parentDiv, 200);
// or
scrollToCenter($innerListItem, $parentDiv, 200);
Use the ampersand just like you would from the shell.
#!/usr/bin/bash
function_to_fork() {
...
}
function_to_fork &
# ... execution continues in parent process ...
What I was doing wrong so I got this error is I wasn't instantiating dynamic layout and adding childs to it so got this error
This is an old thread, but I thought I would mention, of your phone has root, you can view it directly on your phone using the root explorer app. You don't even have to extract it to see.
As mentioned in the above answers, yes file must be used maybe by other java processes, simple way to get rid-off this is, just kill all java processes then execute git pull
I did this, it works for me.
For windows kill all java processes:
taskkill /F /IM java.exe
For Linux kill all java processes:
kill -9 `pidof java`

This is for Visual Studio 2015 and I had already made a repository on Github.com
If you already have your repository URL copy it and then in visual studio:
Singleton classes in TypeScript are generally an anti-pattern. You can simply use namespaces instead.
class Singleton {
/* ... lots of singleton logic ... */
public someMethod() { ... }
}
// Using
var x = Singleton.getInstance();
x.someMethod();
export namespace Singleton {
export function someMethod() { ... }
}
// Usage
import { SingletonInstance } from "path/to/Singleton";
SingletonInstance.someMethod();
var x = SingletonInstance; // If you need to alias it for some reason
You can also use list subsetting to select the element you want to convert. It would be useful if your list had more than 1 element.
as.numeric(a[[1]])
It should be like this.
In your Component
computed: {
...mapGetters({
nameFromStore: 'name'
}),
name: {
get(){
return this.nameFromStore
},
set(newName){
return newName
}
}
}
In your store
export const store = new Vuex.Store({
state:{
name : "Stackoverflow"
},
getters: {
name: (state) => {
return state.name;
}
}
}
Simply check if there is a protocol (delineated by "://") and add "http://" if there isn't.
if (false === strpos($url, '://')) {
$url = 'http://' . $url;
}
Note: This may be a simple and straightforward solution, but Jack's answer using parse_url
is almost as simple and much more robust. You should probably use that one.
I was getting the same messages while I was running just msbuild from powershell.
dotnet msbuild "./project.csproj"

Apart from what others have mentioned, I would like to add that, Linting will run through your source code to find
- formatting discrepancy
- non-adherence to coding standards and conventions
- pinpointing possible logical errors in your program
Running a Lint program over your source code, helps to ensure that source code is legible, readable, less polluted and easier to maintain.
By specifying the positions we can achieve this,
.div1 {
width:300px;
height: auto;
background-color: grey;
border:1px solid;
position:relative;
overflow:auto;
}
.div2 {
width:150px;
height:auto;
background-color: #F4A460;
float:left;
}
.div3 {
width:150px;
height:100%;
position:absolute;
right:0px;
background-color: #FFFFE0;
float:right;
}
but it is not possible to achieve this using float.
For MySQL, please find the below query:
select * from (select PartID, max(Pricedate) max_pricedate from MyPrices group bu partid) as a
inner join MyParts b on
(a.partid = b.partid and a.max_pricedate = b.pricedate)
Inside the subquery it fetches max pricedate for every partyid of MyPrices then, inner joining with MyParts using partid and the max_pricedate
I researched a lot of information about how to open new tab and stay on the same tab. I have found one small trick to do it. Lets assume you have url which you need to open - newUrl and old url - currentUrl, which you need to stay on after new tab opened. JS code will look something like next:
// init urls
let newUrl = 'http://example.com';
let currentUrl = window.location.href;
// open window with url of current page, you will be automatically moved
// by browser to a new opened tab. It will look like your page is reloaded
// and you will stay on same page but with new page opened
window.open(currentUrl , '_blank');
// on your current tab will be opened new url
location.href = newUrl;
EDIT
As of today with flexbox, you could

If your looking for something a little more native, you can use getGnuWin32 to install all of the unix command line tools that have been ported. That plus winBash gives you most of a working unix environment. Add console2 for a better terminal emulator and you almost can't tell your on windows!
Cygwin is a better toolkit overall, but I have found myself running into suprise problems because of the divide between it and windows. None of these solutions are as good as a native linux system though.
You may want to look into using virtualbox to create a linux VM with your distro of choice. Set it up to share a folder with the host os, and you can use a true linux development environment, and share with windows. Just watch out for those EOL markers, they get ya every time.
n = [[1, 2, 3], [4, 5, 6, 7, 8, 9]]
def flatten(lists):
results = []
for numbers in lists:
for numbers2 in numbers:
results.append(numbers2)
return results
print flatten(n)
Output: n = [1,2,3,4,5,6,7,8,9]
why not simply
new Date (timestamp);
A date is a date, the formatting of it is a different matter.

You can create your own user defined functions in a module within Excel such as (from memory, so may need some debugging, and the syntax may vary among Excel versions as well):
Public Function ZeroToBlank (x As Integer) As String
If x = 0 then
ZeroToBlank = ""
Else
ZeroToBlank = CStr(x)
End If
End Function
You can then simply insert =ZeroToBlank (Index (a,b,c))
into your cell.
There's a nice tutorial on just this subject here.
The basic steps are:
Tools -> Macro -> Visual Basic Editor
.Insert -> Module
.=ZeroToBlank (<<whatever>>)
<<whatever>>
is the value you wish to use blank for if it's zero.Note that there may be minor variations depending on which version of Excel you have. My version of Excel is 2002 which admittedly is pretty old, but it still does everything I need of it.
Now (on Boostrap 3 and 4) its simply :
.carousel-inner img {
margin: auto;
}
You can do it best in one pass.
largest and largest2 are set to INT_MIN on entry. Then step through the array. If largest is smaller than the number, largest2 becomes largest, then largest becomes the new number (or smaller than or equal if you want to allow duplicates). If largest is greater then the new number, test largest2.
Note that this algorithm scales to finding the top three or four in an array, before it become too cumbersome and it's better to just sort.
Given a dataset
df <- data.frame( sex = c('M', 'M', 'F', 'F', 'M'),
occupation = c('analyst', 'dentist', 'dentist', 'analyst', 'cook') )
you can subset rows
df[df$sex == 'M',] # To get all males
df[df$occupation == 'analyst',] # All analysts
etc.
If you want to get number of rows, just call the function nrow
such as
nrow(df[df$sex == 'M',])
build it with string.Join
instead:
var parameters = sl.SelProds.Select(x=>"productID="+x.prodID).ToArray();
paramstr = string.Join("&", parameters);
string.Join
takes a seperator ("&"
) and and array of strings (parameters
), and inserts the seperator between each element of the array.
instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0;
once your window has scrolled pass a certain height:
jQuery
$(window).scroll(function(){
if ($(this).scrollTop() > 135) {
$('#task_flyout').addClass('fixed');
} else {
$('#task_flyout').removeClass('fixed');
}
});
css
.fixed {position:fixed; top:0; left:0;}
I have a simple approach, because i have some heavy validations and masks in my forms. So, i used jquery to get my value again and fire the event "change" to validations:
$('#myidelement').val('123');
$('#myidelement').trigger( "change");
You can try joda-time.
There appear to be two problems.
I think you want the following regex @"([^a-zA-Z0-9\s])+"
You can compare an array like the below mentioned if the array has some values
it('should check if the array are equal', function() {
var mockArr = [1, 2, 3];
expect(mockArr ).toEqual([1, 2, 3]);
});
But if the array that is returned from some function has more than 1 elements and all are zero then verify by using
expect(mockArray[0]).toBe(0);
For my case, I was trying to execute procedure code in MySQL, and due to some issue with server in which Server can't figure out where to end the statement I was getting Error Code 1064. So I wrapped the procedure with custom DELIMITER and it worked fine.
For example, Before it was:
DROP PROCEDURE IF EXISTS getStats;
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
/*Procedure Code Here*/
END;
After putting DELIMITER it was like this:
DROP PROCEDURE IF EXISTS getStats;
DELIMITER $$
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
/*Procedure Code Here*/
END;
$$
DELIMITER ;

Transforming object to array with plain JavaScript's(ECMAScript-2016
) Object.values
:
var obj = {_x000D_
22: {name:"John", id:22, friends:[5,31,55], works:{books:[], films:[]}},_x000D_
12: {name:"Ivan", id:12, friends:[2,44,12], works:{books:[], films:[]}}_x000D_

_x000D_
var values = Object.values(obj)_x000D_
_x000D_
console.log(values);
_x000D_
If you also want to keep the keys use Object.entries
and Array#map
like this:
var obj = {_x000D_
22: {name:"John", id:22, friends:[5,31,55], works:{books:[], films:[]}},_x000D_
12: {name:"Ivan", id:12, friends:[2,44,12], works:{books:[], films:[]}}_x000D_

Instead of downloading curl, down libcurl.
curl is just the application, libcurl is what you need for your C++ program
In Java:
String regex = "[^-\\s]";
System.out.println("-".matches(regex)); // prints "false"
System.out.println(" ".matches(regex)); // prints "false"
System.out.println("+".matches(regex)); // prints "true"
The regex [^-\s]
works as expected. [^\s-]
also works.
The hyphen can be included right after the opening bracket, or right before the closing bracket, or right after the negating caret.
Use
System.getProperty("java.class.path")
see http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html
You can also split it into it's elements easily
String classpath = System.getProperty("java.class.path");
String[] classpathEntries = classpath.split(File.pathSeparator);
import os, signal
def check_kill_process(pstring):
for line in os.popen("ps ax | grep " + pstring + " | grep -v grep"):
fields = line.split()
pid = fields[0]
os.kill(int(pid), signal.SIGKILL)
There is a package for this called split.
cabal install split
Use it like this:
ghci> import Data.List.Split
ghci> splitOn "," "my,comma,separated,list"
["my","comma","separated","list"]
It comes with a lot of other functions for splitting on matching delimiters or having several delimiters.
I created this test case: http://jsfiddle.net/ccQnK/1/ , I used the Javascript replace function with regular expressions to get the results that you want.
$(document).ready(function() {

alert(myContent.replace(/(<([^>]+)>)/ig,""));
});
You need to use something like this:
OracleCommand oraCommand = new OracleCommand("SELECT fullname FROM sup_sys.user_profile
WHERE domain_user_name = :userName", db);
More can be found in this MSDN article: http://msdn.microsoft.com/en-us/library/system.data.oracleclient.oraclecommand.parameters%28v=vs.100%29.aspx
It is advised you use the : character instead of @ for Oracle.

All of these are kinds of indices.
primary: must be unique, is an index, is (likely) the physical index, can be only one per table.
unique: as it says. You can't have more than one row with a tuple of this value. Note that since a unique key can be over more than one column, this doesn't necessarily mean that each individual column in the index is unique, but that each combination of values across these columns is unique.
index: if it's not primary or unique, it doesn't constrain values inserted into the table, but it does allow them to be looked up more efficiently.
fulltext: a more specialized form of indexing that allows full text search. Think of it as (essentially) creating an "index" for each "word" in the specified column.

Array.prototype.filter.call(
document.getElementsByTagName('span'),
function(el) {return el.getAttribute('property') == 'v.name';}
);
In future
Array.prototype.filter.call(
document.getElementsByTagName('span'),
(el) => el.getAttribute('property') == 'v.name'
)
Intro
The call() method calls a function with a given this value and arguments provided individually.
The filter() method creates a new array with all elements that pass the test implemented by the provided function.
Given this html markup
<span property="a">apple - no match</span>
<span property="v:name">onion - match</span>
<span property="b">root - match</span>
<span property="v:name">tomato - match</span>
<br />
<button onclick="findSpan()">find span</button>
you can use this javascript
function findSpan(){
var spans = document.getElementsByTagName('span');
var spansV = Array.prototype.filter.call(
spans,
function(el) {return el.getAttribute('property') == 'v:name';}
);
return spansV;
}

This worked for me inside package.json as an npm script but it does seem to take to long grabbing the packages even though I have them as dev dependancies. It also seems too long.
"babel": "npx -p @babel/cli -p @babel/core babel --version"
What end up solving it was much simpler but funny too
npm install
I thought I ran that already but I guess somethings needed to be rebuilt. Then just:
"babel": "babel --version"
Try vi with the -b option, this will show special end of line characters (I typically use it to see windows line endings in a txt file on a unix OS)
But if you want a scripted solution obviously vi wont work so you can try the -f or -e options with grep and pipe the result into sed or awk. From grep man page:
Matcher Selection -E, --extended-regexp Interpret PATTERN as an extended regular expression (ERE, see below). (-E is specified by POSIX.)
-F, --fixed-strings
Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched. (-F is specified
by POSIX.)
