Some code for a variation on this problem. Using the above code got me my click events as needed, but I was then stuck trying to work out which button had been clicked. My scenario is I have a dynamic amount of tab pages. On each tab page are (all dynamically created) 2 charts, 2 DGVs and a pair of radio buttons. Each control has a unique name relative to the tab, but there could be 20 radio buttons with the same name if I had 20 tab pages. The radio buttons switch between which of the 2 graphs and DGVs you get to see. Here is the code for when one of the radio buttons gets checked (There's a nearly identical block that swaps the charts and DGVs back):
Private Sub radioFit_Components_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
If sender.name = "radioFit_Components" And sender.visible Then
If sender.checked Then
For Each ctrl As Control In TabControl1.SelectedTab.Controls
Select Case ctrl.Name
Case "embChartSSE_Components"
ctrl.BringToFront()
Case "embChartSSE_Fit_Curve"
ctrl.SendToBack()
Case "dgvFit_Components"
ctrl.BringToFront()
End Select
Next
End If
End If
End Sub
This code will fire for any of the tab pages and swap the charts and DGVs over on any of the tab pages. The sender.visible check is to stop the code firing when the form is being created.
For future visitors - use this for range: ($A$1:$A$10)
Example
=COUNTIF($G$6:$G$9;J6)>0
SQL Server by default uses the mdy
date format and so the below works:
SELECT convert(datetime, '07/23/2009', 111)
and this does not work:
SELECT convert(datetime, '23/07/2009', 111)
I myself have been struggling to come up with a single query that can handle both date formats: mdy
and dmy
.
However, you should be ok with the third date format - ymd
.
this is what I added in my .bashrc file and worked.
export PATH="$PATH:/home/myUsername/.composer/vendor/bin"
Just thought I'd throw this out there as well.
I haven't been able to test it in older browsers, but it works in the latest of the top 3. :)
Element.prototype.getOffsetTop = function() {

};
Element.prototype.getOffset = function() {
return {'left':this.getOffsetLeft(),'top':this.getOffsetTop()};
};
I had a similar problem. I had to add the same android sdk that i used before again and it worked.
You could possibly set a cookie at an expiration date of a month or something and then reassign the cookie every time the user visits the website again
I can handle this way:
select to_number(to_char(sysdate,'MI')) - to_number(to_char(*YOUR_DATA_VALUE*,'MI')),max(exp_time) from ...
Or if you want to the hour just change the MI;
select to_number(to_char(sysdate,'HH24')) - to_number(to_char(*YOUR_DATA_VALUE*,'HH24')),max(exp_time) from ...
the others don't work for me. Good luck.
this will work for all sort of youtube url :
if url could be
youtube.com/?v=_RCIP6OrQrE
youtube.com/v/_RCIP6OrQrE
youtube.com/watch?v=_RCIP6OrQrE
youtube.com/watch?v=_RCIP6OrQrE&feature=whatever&this=that
Pattern p = Pattern.compile("http.*\\?v=([a-zA-Z0-9_\\-]+)(?:&.)*");
String url = "http://www.youtube.com/watch?v=_RCIP6OrQrE";
Matcher m = p.matcher(url.trim()); //trim to remove leading and trailing space if any
if (m.matches()) {
url = m.group(1);
}
System.out.println(url);
this will extract video id from your url

To see the devices I was interested in, I had replace Win32_USBHub
by Win32_PnPEntity
in Adel Hazzah's code, based on this post. This works for me:
namespace ConsoleApplication1
{
using System;
using System.Collections.Generic;
using System.Management; // need to add System.Management to your project references.
class Program
{
static void Main(string[] args)
{
var usbDevices = GetUSBDevices();
foreach (var usbDevice in usbDevices)
{
Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}",
usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description);
}
Console.Read();
}
static List<USBDeviceInfo> GetUSBDevices()
{
List<USBDeviceInfo> devices = new List<USBDeviceInfo>();
ManagementObjectCollection collection;
using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_PnPEntity"))
collection = searcher.Get();
foreach (var device in collection)
{
devices.Add(new USBDeviceInfo(
(string)device.GetPropertyValue("DeviceID"),
(string)device.GetPropertyValue("PNPDeviceID"),
(string)device.GetPropertyValue("Description")
));
}
collection.Dispose();
return devices;
}
}
class USBDeviceInfo
{
public USBDeviceInfo(string deviceID, string pnpDeviceID, string description)
{
this.DeviceID = deviceID;
this.PnpDeviceID = pnpDeviceID;
this.Description = description;
}
public string DeviceID { get; private set; }
public string PnpDeviceID { get; private set; }
public string Description { get; private set; }
}
}
The "bind" operation is basically saying, "use this local UDP port for sending and receiving data. In other words, it allocates that UDP port for exclusive use for your application. (Same holds true for TCP sockets).
When you bind to "0.0.0.0" (INADDR_ANY
), you are basically telling the TCP/IP layer to use all available adapters for listening and to choose the best adapter for sending. This is standard practice for most socket code. The only time you wouldn't specify 0 for the IP address is when you want to send/receive on a specific network adapter.
Similarly if you specify a port value of 0 during bind, the OS will assign a randomly available port number for that socket. So I would expect for UDP multicast, you bind to INADDR_ANY on a specific port number where multicast traffic is expected to be sent to.
The "join multicast group" operation (IP_ADD_MEMBERSHIP
) is needed because it basically tells your network adapter to listen not only for ethernet frames where the destination MAC address is your own, it also tells the ethernet adapter (NIC) to listen for IP multicast traffic as well for the corresponding multicast ethernet address. Each multicast IP maps to a multicast ethernet address. When you use a socket to send to a specific multicast IP, the destination MAC address on the ethernet frame is set to the corresponding multicast MAC address for the multicast IP. When you join a multicast group, you are configuring the NIC to listen for traffic sent to that same MAC address (in addition to its own).
Without the hardware support, multicast wouldn't be any more efficient than plain broadcast IP messages. The join operation also tells your router/gateway to forward multicast traffic from other networks. (Anyone remember MBONE?)
If you join a multicast group, all the multicast traffic for all ports on that IP address will be received by the NIC. Only the traffic destined for your binded listening port will get passed up the TCP/IP stack to your app. In regards to why ports are specified during a multicast subscription - it's because multicast IP is just that - IP only. "ports" are a property of the upper protocols (UDP and TCP).
You can read more about how multicast IP addresses map to multicast ethernet addresses at various sites. The Wikipedia article is about as good as it gets:
The IANA owns the OUI MAC address 01:00:5e, therefore multicast packets are delivered by using the Ethernet MAC address range 01:00:5e:00:00:00 - 01:00:5e:7f:ff:ff. This is 23 bits of available address space. The first octet (01) includes the broadcast/multicast bit. The lower 23 bits of the 28-bit multicast IP address are mapped into the 23 bits of available Ethernet address space.
Methods 1 and 2 work in Python 2 or 3, and they work on ragged, rectangular 2D lists. That means the inner lists do not need to have the same lengths as each other (ragged) or as the outer lists (rectangular). The other methods, well, it's complicated.
import itertools
import six
list_list = [[1,2,3], [4,5,6, 6.1, 6.2, 6.3], [7,8,9]]
map()
, zip_longest()
>>> list(map(list, six.moves.zip_longest(*list_list, fillvalue='-')))
[[1, 4, 7], [2, 5, 8], [3, 6, 9], ['-', 6.1, '-'], ['-', 6.2, '-'], ['-', 6.3, '-']]
six.moves.zip_longest()
becomes
itertools.izip_longest()
in Python 2itertools.zip_longest()
in Python 3The default fillvalue is None
. Thanks to @jena's answer, where map()
is changing the inner tuples to lists. Here it is turning iterators into lists. Thanks to @Oregano's and @badp's comments.
In Python 3, pass the result through list()
to get the same 2D list as method 2.
zip_longest()
>>> [list(row) for row in six.moves.zip_longest(*list_list, fillvalue='-')]
[[1, 4, 7], [2, 5, 8], [3, 6, 9], ['-', 6.1, '-'], ['-', 6.2, '-'], ['-', 6.3, '-']]
The @inspectorG4dget alternative.
map()
of map()
— broken in Python 3.6>>> map(list, map(None, *list_list))
[[1, 4, 7], [2, 5, 8], [3, 6, 9], [None, 6.1, None], [None, 6.2, None], [None, 6.3, None]]
This extraordinarily compact @SiggyF second alternative works with ragged 2D lists, unlike his first code which uses numpy to transpose and pass through ragged lists. But None has to be the fill value. (No, the None passed to the inner map() is not the fill value. It means there is no function to process each column. The columns are just passed through to the outer map() which converts them from tuples to lists.)
Somewhere in Python 3, map()
stopped putting up with all this abuse: the first parameter cannot be None, and ragged iterators are just truncated to the shortest. The other methods still work because this only applies to the inner map().
map()
of map()
revisited>>> list(map(list, map(lambda *args: args, *list_list)))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]] // Python 2.7
[[1, 4, 7], [2, 5, 8], [3, 6, 9], [None, 6.1, None], [None, 6.2, None], [None, 6.3, None]] // 3.6+
Alas the ragged rows do NOT become ragged columns in Python 3, they are just truncated. Boo hoo progress.

Don't use the Android Virtual Device with too low configuration. Let it be medium.
In vi
...
:set list
to see line-endings.
:set nolist
to go back to normal.
While I don't think you can see \n
or \r\n

:set ff
Alternatively, from bash
you can use od -t c <filename>
or just od -c <filename>
to display the returns.

The stackLevel
depends on depth you call this method. You can try from 0 to a large number to see what difference.
If stackLevel
is legal, you will get string like java.lang.Thread.getStackTrace(Thread.java:1536)
public static String getCodeLocationInfo(int stackLevel) {
StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace();
if (stackLevel < 0 || stackLevel >= stackTraceElements.length) {
return "Stack Level Out Of StackTrace Bounds";
}
StackTraceElement stackTraceElement = stackTraceElements[stackLevel];
String fullClassName = stackTraceElement.getClassName();
String methodName = stackTraceElement.getMethodName();
String fileName = stackTraceElement.getFileName();
int lineNumber = stackTraceElement.getLineNumber();
return String.format("%s.%s(%s:%s)", fullClassName, methodName, fileName, lineNumber);
}
The shortcuts I use in Visual Studio for multiline (aka box) select are Shift + Alt + up/down/left/right
To create this in Visual Studio Code you can add these keybindings to the keybindings.json file (menu File → Preferences → Keyboard shortcuts).
{ "key": "shift+alt+down", "command": "editor.action.insertCursorBelow",
"when": "editorTextFocus" },
{ "key": "shift+alt+up", "command": "editor.action.insertCursorAbove",
"when": "editorTextFocus" },
{ "key": "shift+alt+right", "command": "cursorRightSelect",
"when": "editorTextFocus" },
{ "key": "shift+alt+left", "command": "cursorLeftSelect",
"when": "editorTextFocus" }
In selection formula try this
Date(Year({datetimefield}), Month({datetimefield}), Day({datetimefield}))
For those using Telerik as mentioned by Ovar, make sure you wrap your javascript in
<telerik:RadScriptBlock ID="radSript1" runat="server">
<script type="text/javascript">
//Your javascript
</script>
</telerik>
Since Telerik doesn't recognize <%# %> when looking for an element and <%= %> will give you an error if your javascript code isn't wrapped.

Update 2019
I tried easy_install at first but it doesn't install packages in a clean and intuitive way. Also when it comes time to remove packages it left a lot of artifacts that needed to be cleaned up.
sudo yum install epel-release
sudo yum install python34-pip
pip install package
Was the solution that worked for me, it installs "pip3" as pip on the system. It also uses standard rpm structure so it clean in its removal. I am not sure what process you would need to take if you want both python2 and python3 package manager on your system.
Swift 4 • iOS 11.2.1 or later
extension ISO8601DateFormatter {
convenience init(_ formatOptions: Options) {
self.init()
self.formatOptions = formatOptions
}
}
extension Formatter {
static let iso8601withFractionalSeconds = ISO8601DateFormatter([.withInternetDateTime, .withFractionalSeconds])
}
extension Date {
var iso8601withFractionalSeconds: String { return Formatter.iso8601withFractionalSeconds.string(from: self) }
}
extension String {
var iso8601withFractionalSeconds: Date? { return Formatter.iso8601withFractionalSeconds.date(from: self) }

Codable Protocol
If you need to encode and decode this format when working with Codable protocol you can create your own custom date encoding/decoding strategies:
extension JSONDecoder.DateDecodingStrategy {
static let iso8601withFractionalSeconds = custom {
let container = try $0.singleValueContainer()
let string = try container.decode(String.self)
guard let date = Formatter.iso8601withFractionalSeconds.date(from: string) else {
throw DecodingError.dataCorruptedError(in: container,
debugDescription: "Invalid date: " + string)
}
return date
}
}
and the encoding strategy
extension JSONEncoder.DateEncodingStrategy {
static let iso8601withFractionalSeconds = custom {
var container = $1.singleValueContainer()
try container.encode(Formatter.iso8601withFractionalSeconds.string(from: $0))
}
}
Playground Testing
let dates = [Date()] // ["Feb 8, 2019 at 9:48 PM"]
encoding
let encoder = JSONEncoder()
encoder.dateEncodingStrategy = .iso8601withFractionalSeconds
let data = try! encoder.encode(dates)
print(String(data: data, encoding: .utf8)!)
decoding
let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .iso8601withFractionalSeconds
let decodedDates = try! decoder.decode([Date].self, from: data) // ["Feb 8, 2019 at 9:48 PM"]

In Python 3.8+ you can do
import hashlib
with open("your_filename.png", "rb") as f:
file_hash = hashlib.md5()
while chunk := f.read(8192):
file_hash.update(chunk)
print(file_hash.digest())
print(file_hash.hexdigest()) # to get a printable str instead of bytes
On Python 3.7 and below:
with open("your_filename.png", "rb") as f:
file_hash = hashlib.md5()
chunk = f.read(8192)
while chunk:
file_hash.update(chunk)
chunk = f.read(8192)
print(file_hash.hexdigest())
This reads the file 8192 (or 2¹³) bytes at a time instead of all at once with f.read()
to use less memory.
Consider using hashlib.blake2b
instead of md5
(just replace md5
with blake2b
in the above snippets). It's cryptographically secure and faster than MD5.
I use classnames when there is a fair amount of logic required for deciding the classes to (not) use. An overly simple example:
...
var liClasses = classNames({
'main-class': true,
'activeClass': self.state.focused === index
});
return (<li className={liClasses}>{data.name}</li>);
...
That said, if you don't want to include a dependency then there are better answers below.
we can easily stop the set interval by calling clear interval
var count = 0 , i = 5;
var vary = function intervalFunc() {
count++;
console.log(count);
console.log('hello boy');
if (count == 10) {
clearInterval(this);
}
}
setInterval(vary, 1500);
Adding this intent filter to one of the activities declared in app manifest fixed this for me.
<activity

</intent-filter>

Since most of us like oneliners:
Convert.ToBase64String(File.ReadAllBytes(imageFilepath));
If you need it as Base64 byte array:
Encoding.ASCII.GetBytes(Convert.ToBase64String(File.ReadAllBytes(imageFilepath)));
To sum it all up, the correct answer is :
select * from db where Date >= '20100401' (Format of date yyyymmdd)
This will avoid any problem with other language systems and will use the index.
If you want to use a class:
from datetime import datetime,timedelta
class MyThread():
def __init__(self, name, timeLimit):
self.name = name
self.timeLimit = timeLimit
def run(self):
# get the start time
startTime = datetime.now()
while True:
# stop if the time limit is reached :
if((datetime.now()-startTime)>self.timeLimit):
break
print('A')
mt = MyThread('aThread',timedelta(microseconds=20000))
mt.run()
MY PREFERRED METHOD is using fopen,fwrite and fclose [it will cost less CPU]
$f=fopen('myfile.txt','w');
fwrite($f,'new content');
fclose($f);
Warning for those using file_put_contents
It'll affect a lot in performance, for example [on the same class/situation] file_get_contents too: if you have a BIG FILE, it'll read the whole content in one shot and that operation could take a long waiting time

# df_new = df.withColumn(i, [do-something])
print i

How are you running the application? Are you just hitting the website or are you building and running from within Visual Studio? If you are building and running you may want to tell it to use the local IIS web server. This would make sure it is using the App Pool you have set up to run with v4.0/integrated.
I am guessing that it is using the Visual Studio Development Server when running. This server is probably trying to run with the 2.0 framework. This then causes your error to be thrown.
Edit: To note, I normally just build my website application and then I attach to process w3wp when I want to debug. I do not use the publishing tool. Of course this means my local working directory is within the web root.

Then run:

The problem you have found is that view
is different from your UIView
. 'view' refers to the entire view. For example your home screen is a view.
You need to clearly separate the entire 'view' your 'UIView' and your 'UILabel'
You can accomplish this by going to your storyboard, clicking on the item, Identity Inspector, and changing the Restoration ID
.
Now to access each item in your code using the restoration ID

If you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward. If you started with a concrete type and you decided to change to another one, even if it uses the same interface, you're going to break someone else's code unless you started off with an interface or abstract base type.
In your /etc/nginx/nginx.conf
file you have:
include /etc/nginx/site-enabled/*;
And probably the path you are using is:
/etc/nginx/sites-enabled/default
Notice the missing s in site.
Those who installed node.js via the package manager can just run:
sudo apt-get purge nodejs
Optionally if you have installed it by adding the official NodeSource repository as stated in Installing Node.js via package manager, do:
sudo rm /etc/apt/sources.list.d/nodesource.list
If you want to clean up npm cache as well:
rm -rf ~/.npm
It is bad practice to try to remove things manually, as it can mess up the package manager, and the operating system itself. This answer is completely safe to follow

Alternatively you can do either of the following lines. Also O(n) but only one iteration
a.each_with_object(Hash.new(0).merge dup: []){|x,h| h[:dup] << x if (h[x] += 1) == 2}[:dup]
a.inject(Hash.new(0).merge dup: []){|h,x| h[:dup] << x if (h[x] += 1) == 2;h}[:dup]
For those using frameworks that compress, bundle, and minify files, make sure you define each dependency explicitly as these frameworks tend to rename your variables. That happened to me while using ASP.NET BundleConfig.cs
to bundle my app scripts together.
Before
app.config(function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'list.html',
controller: 'ListController'
}).
when('/items/:itemId', {
templateUrl: 'details.html',
controller: 'DetailsController'
}).
otherwise({
redirectTo: '/'
});
});
After
app.config(["$routeProvider", function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'list.html',
controller: 'ListController'
}).
when('/items/:itemId', {
templateUrl: 'details.html',
controller: 'DetailsController'
}).
otherwise({
redirectTo: '/'
});
}]);

You can use standard looping constructs or iterator/listiterator for the same :
List<Integer> list = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8);
double sum = 0;
Iterator<Integer> iter1 = list.iterator();
while (iter1.hasNext()) {
sum += iter1.next();
}
double average = sum / list.size();
System.out.println("Average = " + average);
If using Java 8, you could use Stream or IntSream operations for the same :
OptionalDouble avg = list.stream().mapToInt(Integer::intValue).average();
System.out.println("Average = " + avg.getAsDouble());

I found this problem continued even when setting the BODY MARGIN to zero.
However it turns out there is an easy fix. All you need to do is give your HEADER tag a 1px border, aswell as setting the BODY MARGIN to zero, as shown below.
body { margin:0px; }
header { border:1px black solid; }
If you have any H1, H2, tags within your HEADER you will also need to set the MARGIN for these tags to zero, this will get rid of any extra space which may show up.
Not sure why this works, but I use Chrome browser. Obviously you can also change the colour of the border to match your header colour.
I'm not a fan of using modules when they are not needed. This job only requires simple math, so here is my simple function to do the job:
def ipToInt(ip):
o = map(int, ip.split('.'))
res = (16777216 * o[0]) + (65536 * o[1]) + (256 * o[2]) + o[3]
return res
def isIpInSubnet(ip, ipNetwork, maskLength):
ipInt = ipToInt(ip)#my test ip, in int form
maskLengthFromRight = 32 - maskLength
ipNetworkInt = ipToInt(ipNetwork) #convert the ip network into integer form
binString = "{0:b}".format(ipNetworkInt) #convert that into into binary (string format)
chopAmount = 0 #find out how much of that int I need to cut off
for i in range(maskLengthFromRight):
if i < len(binString):
chopAmount += int(binString[len(binString)-1-i]) * 2**i
minVal = ipNetworkInt-chopAmount
maxVal = minVal+2**maskLengthFromRight -1
return minVal <= ipInt and ipInt <= maxVal
Then to use it:
>>> print isIpInSubnet('66.151.97.0', '66.151.97.192',24)
True
>>> print isIpInSubnet('66.151.97.193', '66.151.97.192',29)
True
>>> print isIpInSubnet('66.151.96.0', '66.151.97.192',24)
False
>>> print isIpInSubnet('66.151.97.0', '66.151.97.192',29)
That's it, this is much faster than the solutions above with the included modules.
For TSQL I like to encapsulate case statements in an outer apply. This prevents me from having to have the case statement written twice, allows reference to the case statement by alias in future joins and avoids the need for positional references.
select oa.day,
model.name,
attempt.type,
oa.result
COUNT(*) MyCount
FROM attempt attempt, prod_hw_id prod_hw_id, model model
WHERE time >= '2013-11-06 00:00:00'
AND time < '2013-11-07 00:00:00'
AND attempt.hard_id = prod_hw_id.hard_id
AND prod_hw_id.model_id = model.model_id
OUTER APPLY (
SELECT CURRENT_DATE-1 AS day,
CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END result
) oa
group by oa.day,
model.name,
attempt.type,
oa.result
order by model.name, attempt.type, oa.result;
I made this for my simple text editor.

When is something considered so obscene as to be something that can be regulated despite the 1st Amendment guarantee to free speech? According to Justice Potter Stewart, "I know it when I see it." The same holds here.
I hate making hard and fast rules like this because the answer changes not only depending on the size and scope of your project, but I think it changes even down to the module level. Depending on what your method is doing, or what the class is supposed to represent, it's quite possible that 2 arguments is too many and is a symptom of too much coupling.
I would suggest that by asking the question in the first place, and qualifying your question as much as you did, that you really know all of this. The best solution here is not to rely on a hard and fast number, but instead look towards design reviews and code reviews among your peers to identify areas where you have low cohesion and tight coupling.
Never be afraid to show your colleagues your work. If you are afraid to, that's probably the bigger sign that something is wrong with your code, and that you already know it.
A regular expression can be used to offer more control over the whitespace characters that are combined.
To match unicode whitespace:
import re
_RE_COMBINE_WHITESPACE = re.compile(r"\s+")
my_str = _RE_COMBINE_WHITESPACE.sub(" ", my_str).strip()
To match ASCII whitespace only:
import re
_RE_COMBINE_WHITESPACE = re.compile(r"(?a:\s+)")
_RE_STRIP_WHITESPACE = re.compile(r"(?a:^\s+|\s+$)")
my_str = _RE_COMBINE_WHITESPACE.sub(" ", my_str)
my_str = _RE_STRIP_WHITESPACE.sub("", my_str)
Matching only ASCII whitespace is sometimes essential for keeping control characters such as x0b, x0c, x1c, x1d, x1e, x1f.
About \s
:
For Unicode (str) patterns: Matches Unicode whitespace characters (which includes [ \t\n\r\f\v], and also many other characters, for example the non-breaking spaces mandated by typography rules in many languages). If the ASCII flag is used, only [ \t\n\r\f\v] is matched.
About re.ASCII
:
Make \w, \W, \b, \B, \d, \D, \s and \S perform ASCII-only matching instead of full Unicode matching. This is only meaningful for Unicode patterns, and is ignored for byte patterns. Corresponds to the inline flag (?a).
strip()
will remote any leading and trailing whitespaces.
catch (Exception ex) { ... }
WILL catch RuntimeException.
Whatever you put in catch block will be caught as well as the subclasses of it.
Caution:
np.array_split
doesn't work with numpy-1.9.0. I checked out: It works with 1.8.1.
Error:
Dataframe has no 'size' attribute
If you have an array of a known type or is a subclass of Object[] you can cast the array first.
Object array = new ????[n];
Object[] array2 = (Object[]) array;
System.out.println(array2.length);
or
Object array = new char[n];
char[] array2 = (char[]) array;
System.out.println(array2.length);
However if you have no idea what type of array it is you can use Array.getLength(Object);
System.out.println(Array.getLength(new boolean[4]);
System.out.println(Array.getLength(new int[5]);
System.out.println(Array.getLength(new String[6]);
You should be using it like so
<?php
$dbhost = 'localhost';
$dbname = 'pdo';
$dbusername = 'root';
$dbpassword = '845625';
$link = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbusername, $dbpassword);
$statement = $link->prepare('INSERT INTO testtable (name, lastname, age)
VALUES (:fname, :sname, :age)');
$statement->execute([
'fname' => 'Bob',
'sname' => 'Desaunois',
'age' => '18',
]);
Prepared statements are used to sanitize your input, and to do that you can use :foo
without any single quotes within the SQL to bind variables, and then in the execute()
function you pass in an associative array of the variables you defined in the SQL statement.
You may also use ?
instead of :foo
and then pass in an array of just the values to input like so;
$statement = $link->prepare('INSERT INTO testtable (name, lastname, age)
VALUES (?, ?, ?)');
$statement->execute(['Bob', 'Desaunois', '18']);
Both ways have their advantages and disadvantages. I personally prefer to bind the parameter names as it's easier for me to read.

IGNORING_ARRAY_ORDER - ignores order in arrays

Updated with the theme()
function, ggsave()
and the code for the legend background:
df <- data.frame(y = d, x = 1, group = rep(c("gr1", "gr2"), 50))
p <- ggplot(df) +
stat_boxplot(aes(x = x, y = y, color = group),
fill = "transparent" # for the inside of the boxplot
)
Fastest way is using using rect
, as all the rectangle elements inherit from rect:
p <- p +
theme(
rect = element_rect(fill = "transparent") # all rectangles
)
p
More controlled way is to use options of theme
:
p <- p +
theme(
panel.background = element_rect(fill = "transparent"), # bg of the panel
plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
panel.grid.major = element_blank(), # get rid of major grid
panel.grid.minor = element_blank(), # get rid of minor grid
legend.background = element_rect(fill = "transparent"), # get rid of legend bg
legend.box.background = element_rect(fill = "transparent") # get rid of legend panel bg
)
p
To save (this last step is important):
ggsave(p, filename = "tr_tst2.png", bg = "transparent")
A version without error-handling:

End Function
This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.
change it to:
$(function () {
var specialElementHandlers = {
'#editor': function (element,renderer) {
return true;
}
};
$('#cmd').click(function () {
var doc = new jsPDF();
doc.fromHTML(
$('#target').html(), 15, 15,
{ 'width': 170, 'elementHandlers': specialElementHandlers },
function(){ doc.save('sample-file.pdf'); }
);
});
});
and it will work.
Any kind of wrapper is good.
With Java 8+, use either an AtomicInteger
:
AtomicInteger ordinal = new AtomicInteger(0);
list.forEach(s -> {
s.setOrdinal(ordinal.getAndIncrement());
});
... or an array:
int[] ordinal = { 0 };
list.forEach(s -> {
s.setOrdinal(ordinal[0]++);
});
With Java 10+:
var wrapper = new Object(){ int ordinal = 0; };
list.forEach(s -> {
s.setOrdinal(wrapper.ordinal++);
});
Note: be very careful if you use a parallel stream. You might not end up with the expected result. Other solutions like Stuart's might be more adapted for those cases.
int
Of course, this is still valid for types other than int
. You only need to change the wrapping type to an AtomicReference
or an array of that type. For instance, if you use a String
, just do the following:
AtomicReference<String> value = new AtomicReference<>();
list.forEach(s -> {
value.set("blah");
});
Use an array:
String[] value = { null };
list.forEach(s-> {
value[0] = "blah";
});
Or with Java 10+:
var wrapper = new Object(){ String value; };
list.forEach(s->{
wrapper.value = "blah";
});
Here's the cleaned up ARC version, based on @elsurudo's code:
- (id)fetchSSIDInfo {
NSArray *ifs = (__bridge_transfer NSArray *)CNCopySupportedInterfaces();
NSLog(@"Supported interfaces: %@", ifs);
NSDictionary *info;
for (NSString *ifnam in ifs) {
info = (__bridge_transfer NSDictionary *)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
NSLog(@"%@ => %@", ifnam, info);
if (info && [info count]) { break; }
}
return info;
}
Include input type="file"
element on your HTML page and on the click event of your button trigger the click event of input type file element using trigger function of jQuery
The code will look like:
<input type="file" id="imgupload" style="display:none"/>
<button id="OpenImgUpload">Image Upload</button>
And on the button's click event write the jQuery code like :
$('#OpenImgUpload').click(function(){ $('#imgupload').trigger('click'); });
This will open File Upload Dialog box on your button click event..
On a Windows machine you can use PortQry from Microsoft to check whether an application is already listening on a specific port using the following command:
portqry -n 11.22.33.44 -p tcp -e 80
Using linear algebra, there exist algorithms that achieve better complexity than the naive O(n3). Solvay Strassen algorithm achieves a complexity of O(n2.807) by reducing the number of multiplications required for each 2x2 sub-matrix from 8 to 7.
The fastest known matrix multiplication algorithm is Coppersmith-Winograd algorithm with a complexity of O(n2.3737). Unless the matrix is huge, these algorithms do not result in a vast difference in computation time. In practice, it is easier and faster to use parallel algorithms for matrix multiplication.
Have you tried using JavaScriptSerializer
?
There's also DataContractJsonSerializer
This can also be done in the GUI. Here's an example adding a multi-column unique constraint to an existing table.
Click OK in each window and you're done.

For cases when we need to check from our own service/background-thread whether our app is in foreground or not. This is how I implemented it, and it works fine for me:
public class TestApplication extends Application implements Application.ActivityLifecycleCallbacks {
public static WeakReference<Activity> foregroundActivityRef = null;
@Override
public void onActivityStarted(Activity activity) {
foregroundActivityRef = new WeakReference<>(activity);
}
@Override
public void onActivityStopped(Activity activity) {
if (foregroundActivityRef != null && foregroundActivityRef.get() == activity) {
foregroundActivityRef = null;
}
}
// IMPLEMENT OTHER CALLBACK METHODS
}
Now to check from other classes, whether app is in foreground or not, simply call:
if(TestApplication.foregroundActivityRef!=null){
// APP IS IN FOREGROUND!
// We can also get the activity that is currently visible!
}
Update (as pointed out by SHS):
Do not forget to register for the callbacks in your Application class's onCreate
method.
@Override
public void onCreate() {
...
registerActivityLifecycleCallbacks(this);
}
You can use list ?? Enumerable.Empty<Friend>()
, or have FindFriends
return Enumerable.Empty<Friend>()
>>> import os
>>> os.path.splitext("1.1.1.1.1.jpg")
('1.1.1.1.1', '.jpg')
This issue can be solved by login into Ubuntu box using below command:

This function will let you specify the number of decimal places to show:
func doubleToString(number:Double, numberOfDecimalPlaces:Int) -> String {
return String(format:"%."+numberOfDecimalPlaces.description+"f", number)
}
Usage:
let numberString = doubleToStringDecimalPlacesWithDouble(number: x, numberOfDecimalPlaces: 2)
File f = new File(Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/FoderName");
if (!f.exists()) {
f.mkdirs();
}
Don't forget that if the list is small and the indexes don't change, as in your example, sometimes the best thing is to use sequence unpacking:
_,a1,a2,_,_,a3,_ = a
The performance is much better and you can also save one line of code:
%timeit _,a1,b1,_,_,c1,_ = a
10000000 loops, best of 3: 154 ns per loop
%timeit itemgetter(*b)(a)
1000000 loops, best of 3: 753 ns per loop
%timeit [ a[i] for i in b]
1000000 loops, best of 3: 777 ns per loop
%timeit map(a.__getitem__, b)
1000000 loops, best of 3: 1.42 µs per loop
UICollectionView implementation is quite interesting. You can use the simple source code and watch a video tutorial using these links :
https://github.com/Ady901/Demo02CollectionView.git
https://www.youtube.com/watch?v=5SrgvZF67Yw
extension ViewController : UICollectionViewDataSource {
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 2
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return nameArr.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "DummyCollectionCell", for: indexPath) as! DummyCollectionCell
cell.titleLabel.text = nameArr[indexPath.row]
cell.userImageView.backgroundColor = .blue
return cell
}
}
extension ViewController : UICollectionViewDelegate {
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let alert = UIAlertController(title: "Hi", message: "\(nameArr[indexPath.row])", preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .default, handler: nil)
alert.addAction(action)
self.present(alert, animated: true, completion: nil)
}
}
Use a format string to round up to two decimal places and convert the double
to a String
:
let currentRatio = Double (rxCurrentTextField.text!)! / Double (txCurrentTextField.text!)!
railRatioLabelField.text! = String(format: "%.2f", currentRatio)
Example:
let myDouble = 3.141
let doubleStr = String(format: "%.2f", myDouble) // "3.14"
If you want to round up your last decimal place, you could do something like this (thanks Phoen1xUK):
let myDouble = 3.141
let doubleStr = String(format: "%.2f", ceil(myDouble*100)/100) // "3.15"
to show which conda env a notebook is using just type in a cell:
!conda info
if you have grep, a more direct way:
!conda info | grep 'active env'
Create a public integer in the General Declaration.
Then in your function you can increase its value each time. See example (function to save attachements of an email as CSV).
Public Numerator As Integer
Public Sub saveAttachtoDisk(itm As Outlook.MailItem)
Dim objAtt As Outlook.Attachment
Dim saveFolder As String
Dim FileName As String
saveFolder = "c:\temp\"
For Each objAtt In itm.Attachments
FileName = objAtt.DisplayName & "_" & Numerator & "_" & Format(Now, "yyyy-mm-dd H-mm-ss") & ".CSV"
objAtt.SaveAsFile saveFolder & "\" & FileName
Numerator = Numerator + 1
Set objAtt = Nothing
Next
End Sub
Try using the ISO string
var isodate = new Date().toISOString()

There is a problem with all those solutions floating around using multipliers. Both kkyy and Christoph's solutions are wrong unfortunately.
Please test your code for number 551.175 with 2 decimal places - it will round to 551.17 while it should be 551.18 ! But if you test for ex. 451.175 it will be ok - 451.18. So it's difficult to spot this error at a first glance.
The problem is with multiplying: try 551.175 * 100 = 55117.49999999999 (ups!)
So my idea is to treat it with toFixed() before using Math.round();
function roundFix(number, precision)
{
var multi = Math.pow(10, precision);
return Math.round( (number * multi).toFixed(precision + 1) ) / multi;
}
Please see http://msdn.microsoft.com/en-us/library/aa260631(v=SQL.80).aspx In SQL server a timestamp is not the same as a DateTime column. This is used to uniquely identify a row in a database, not just a table but the entire database. This can be used for optimistic concurrency. for example UPDATE [Job] SET [Name]=@Name, [XCustomData]=@XCustomData WHERE ([ModifiedTimeStamp]=@Original_ModifiedTimeStamp AND [GUID]=@Original_GUID
the ModifiedTimeStamp ensures that you are updating the original data and will fail if another update has occurred to the row.
There isn't much actually in my .vimrc (even if it has 850 lines). Mostly settings and a few common and simple mappings that I was too lazy to extract into plugins.
If you mean "template-files" by "auto-classes", I'm using a template-expander plugin -- on this same site, you'll find the ftplugins I've defined for C&C++ editing, some may be adapted to C# I guess.
Regarding the refactoring aspect, there is a tip dedicated to this subject on http://vim.wikia.com ; IIRC the example code is for C#. It inspired me a refactoring plugin that still needs of lot of work (it needs to be refactored actually).
You should have a look at the archives of vim mailing-list, specially the subjects about using vim as an effective IDE. Don't forget to have a look at :make, tags, ...
HTH,
Did you download the script from internet?
Then remove NTFS stream from the file using sysinternal's streams.exe on command line.
cmd> streams.exe .\my.ps1
Now try to run the script again.
I believe you can do this using a Unicode encoding, but I doubt this is what you really want.
The ==
is the unicode value 2A76 so I belive you can do this:
char c = '\u2A76';
I can't test this at the moment but I'd be interested to know if that works for you.
You will need to dig around for the others. Here is a unicode table if you want to look:
I do some quick tests and have the following findings:
1) if using SynchronousQueue:
After the threads reach the maximum size, any new work will be rejected with the exception like below.
Exception in thread "main" java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.FutureTask@3fee733d rejected from java.util.concurrent.ThreadPoolExecutor@5acf9800[Running, pool size = 3, active threads = 3, queued tasks = 0, completed tasks = 0]
at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2047)
2) if using LinkedBlockingQueue:
The threads never increase from minimum size to maximum size, meaning the thread pool is fixed size as the minimum size.
No, you can't use underscore in subdomain but hypen (dash). i.e my-subdomain.agahost.com is acceptable and my_subdomain.agahost.com would not be acceptable.
A little example for JUnit 5 Jupiter, the "RunWith" was removed you now need to use the Extensions using the "@ExtendWith" Annotation.
@ExtendWith(MockitoExtension.class)
class FooTest {
@InjectMocks
ClassUnderTest test = new ClassUnderTest();
@Spy
SomeInject bla = new SomeInject();
}
If you need to hit the database, you need to hit the web server again (for the most part).
What you can do is use AJAX, which makes a request to another script on your site to retrieve data, gets the data, and then updates the input fields you want.
AJAX calls can be made in jquery with the $.ajax() function call, so this will happen
User's browser enters input that fires a trigger that makes an AJAX call
$('input .callAjax').bind('change', function() {
$.ajax({ url: 'script/ajax',
type: json
data: $foo,
success: function(data) {
$('input .targetAjax').val(data.newValue);
});
);
Now you will need to point that AJAX call at script (sounds like you're working PHP) that will do the query you want and send back data.
You will probably want to use the JSON object call so you can pass back a javascript object, that will be easier to use than return XML etc.
The php function json_encode($phpobj); will be useful.
rows = int(input())
cols = int(input())
matrix = []
for i in range(rows):
row = []
for j in range(cols):
row.append(0)
matrix.append(row)
print(matrix)
Why such a long code, that too in Python
you ask?
Long back when I was not comfortable with Python, I saw the single line answers for writing 2D matrix and told myself I am not going to use 2-D matrix in Python again. (Those single lines were pretty scary and It didn't give me any information on what Python was doing. Also note that I am not aware of these shorthands.)
Anyways, here's the code for a beginner whose coming from C, CPP and Java background
Note to Python Lovers and Experts: Please do not down vote just because I wrote a detailed code.
Component
import { Component, ElementRef, ViewChild, AfterViewInit} from '@angular/core';
...
@ViewChild('input1', {static: false}) inputEl: ElementRef;
ngAfterViewInit() {
setTimeout(() => this.inputEl.nativeElement.focus());
}
HTML
<input type="text" #input1>
You could also use a LEFT JOIN and IS NULL condition:
SELECT
mac,
creation_date
FROM
logs
LEFT JOIN consols ON logs.mac = consols.mac
WHERE
logs_type_id=11
AND
consols.mac IS NULL;
An index on the "mac" columns might improve performance.
you may consider this example
//Form1 Window
//EventHandler
Form1 frm2 = new Form1();
{
frm2.Show(this); //this will show Form2
frm1.Hide(); //this Form will hide
}
Use window.open()
:
var win = window.open('http://stackoverflow.com/', '_blank');
if (win) {
//Browser has allowed it to be opened
win.focus();
} else {
//Browser has blocked it
alert('Please allow popups for this website');
}
Depending on the browsers implementation this will work
There is nothing you can do to make it open in a window rather than a tab.
Here is the solution I found: On the project tree "app", right click mouse button to get the context menu. Select "open module setting", on the tree "app" - "properties" tab, select the existing "build tools version" you have. The gradle will start to build.
For UTC:
string unixTimestamp = Convert.ToString((int)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);
For local system:
string unixTimestamp = Convert.ToString((int)DateTime.Now.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);
2 possible reasons:
It's fine just to cast your int to Foo:
int i = 1;
Foo f = (Foo)i;
If you try to cast a value that's not defined it will still work. The only harm that may come from this is in how you use the value later on.
If you really want to make sure your value is defined in the enum, you can use Enum.IsDefined:
int i = 1;
if (Enum.IsDefined(typeof(Foo), i))
{
Foo f = (Foo)i;
}
else
{
// Throw exception, etc.
}
However, using IsDefined costs more than just casting. Which you use depends on your implemenation. You might consider restricting user input, or handling a default case when you use the enum.
Also note that you don't have to specify that your enum inherits from int; this is the default behavior.
Padding by definition is a positive integer (including 0).
Negative padding would cause the border to collapse into the content (see the box-model page on w3) - this would make the content area smaller than the content, which doesn't make sense.
Pure JavaScript answer:
document.querySelector('.menu').classList.contains('active');
Might help someone someday.
Run your script with .
. myscript.sh
This will run the script in the current shell environment.
export
governs which variables will be available to new processes, so if you say
FOO=1
export BAR=2
./runScript.sh
then $BAR
will be available in the environment of runScript.sh
, but $FOO
will not.
With POST you can also do multipart mime encoding which means you can attach files as well. Also if you are using post variables across navigation of pages, the user will get a warning asking if they want to resubmit the post parameter. Typically they look the same in an HTTP request, but you should just stick to POST if you need to "POST" something TO a server and "GET" if you need to GET something FROM a server as that's the way they were intended.
Why not just use a regular for loop?
for(int i = 0; i < 50 && i < listView.Items.Count; i++)
{
ListViewItem lvi = listView.Items[i];
}
Updated to resolve bug pointed out by Ruben and Pragmatrix.
Properties prop = new Properties();
prop.load(...); // FileInputStream
prop.setProperty("key", "value");
prop.store(...); // FileOutputStream
You can use the eq method or selector:
$('ul').find('li').eq(index).css({'background-color':'#343434'});
Using Python 2, calling .lower()
on each string or Unicode object...
string1.lower() == string2.lower()
...will work most of the time, but indeed doesn't work in the situations @tchrist has described.
Assume we have a file called unicode.txt
containing the two strings S?s?f??
and S?S?F?S
. With Python 2:
>>> utf8_bytes = open("unicode.txt", 'r').read()
>>> print repr(utf8_bytes)
'\xce\xa3\xce\xaf\xcf\x83\xcf\x85\xcf\x86\xce\xbf\xcf\x82\n\xce\xa3\xce\x8a\xce\xa3\xce\xa5\xce\xa6\xce\x9f\xce\xa3\n'
>>> u = utf8_bytes.decode('utf8')
>>> print u
S?s?f??
S?S?F?S
>>> first, second = u.splitlines()
>>> print first.lower()
s?s?f??
>>> print second.lower()
s?s?f?s
>>> first.lower() == second.lower()
False
>>> first.upper() == second.upper()
True
The S character has two lowercase forms, ? and s, and .lower()
won't help compare them case-insensitively.
However, as of Python 3, all three forms will resolve to ?, and calling lower() on both strings will work correctly:
>>> s = open('unicode.txt', encoding='utf8').read()
>>> print(s)
S?s?f??
S?S?F?S
>>> first, second = s.splitlines()
>>> print(first.lower())
s?s?f??
>>> print(second.lower())
s?s?f??
>>> first.lower() == second.lower()
True
>>> first.upper() == second.upper()
True
So if you care about edge-cases like the three sigmas in Greek, use Python 3.
(For reference, Python 2.7.3 and Python 3.3.0b1 are shown in the interpreter printouts above.)
I was getting this error while trying to show DatePicker
from Fragment
.
I changed
val datePickerDialog = DatePickerDialog(activity!!.applicationContext, ...)
to
val datePickerDialog = DatePickerDialog(requireContext(), ...)
and it worked just fine.
Just look at the docs:
require_relative
complements the builtin methodrequire
by allowing you to load a file that is relative to the file containing therequire_relative
statement.For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:
require_relative "data/customer_data_1"
The NameVirtualHost option would be a good option.
On macOS:
Cmd + 1
On Windows, probably
Ctrl + (/) near right shift key
I had the same problem. my problem was that the version of the dependency had conflict with the elasticsearch version. check the version in ip:9200 and use the dependency version that match it
The simplest way of doing this would be to add
include_directories(${CMAKE_SOURCE_DIR}/inc)
link_directories(${CMAKE_SOURCE_DIR}/lib)
add_executable(foo ${FOO_SRCS})
target_link_libraries(foo bar) # libbar.so is found in ${CMAKE_SOURCE_DIR}/lib
The modern CMake version that doesn't add the -I and -L
flags to every compiler invocation would be to use imported libraries:
add_library(bar SHARED IMPORTED) # or STATIC instead of SHARED
set_target_properties(bar PROPERTIES
IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/lib/libbar.so"
INTERFACE_INCLUDE_DIRECTORIES "${CMAKE_SOURCE_DIR}/include/libbar"
)
set(FOO_SRCS "foo.cpp")
add_executable(foo ${FOO_SRCS})
target_link_libraries(foo bar) # also adds the required include path
If setting the INTERFACE_INCLUDE_DIRECTORIES
doesn't add the path, older versions of CMake also allow you to use target_include_directories(bar PUBLIC /path/to/include)
. However, this no longer works with CMake 3.6 or newer.
If you're trying to just count how many of your cells in a range are not blank try this:
=COUNTA(range)
Example: (assume that it starts from A1 downwards):
---------
Something
---------
Something
---------
---------
Something
---------
---------
Something
---------
=COUNTA(A1:A6)
returns 4
since there are two blank cells in there.
This is not right. Here's how you should use Runtime.exec()
. You might also try its more modern cousin, ProcessBuilder
:
Dividing the app into blueprints is a great idea. However, if this isn't enough, and if you want to then divide the Blueprint itself into multiple py files, this is also possible using the regular Python module import system, and then looping through all the routes that get imported from the other files.
I created a Gist with the code for doing this:
https://gist.github.com/Jaza/61f879f577bc9d06029e
As far as I'm aware, this is the only feasible way to divide up a Blueprint at the moment. It's not possible to create "sub-blueprints" in Flask, although there's an issue open with a lot of discussion about this:
https://github.com/mitsuhiko/flask/issues/593
Also, even if it were possible (and it's probably do-able using some of the snippets from that issue thread), sub-blueprints may be too restrictive for your use case anyway - e.g. if you don't want all the routes in a sub-module to have the same URL sub-prefix.
There were too many projects in my solution to go through and individually update so I fixed this by:
As of Angular 6+, this is handled slightly differently than in previous versions. As @BeetleJuice mentions in the answer above, paramMap
is new interface for getting route params, but the execution is a bit different in more recent versions of Angular. Assuming this is in a component:
private _entityId: number;
constructor(private _route: ActivatedRoute) {
// ...
}
ngOnInit() {
// For a static snapshot of the route...
this._entityId = this._route.snapshot.paramMap.get('id');
// For subscribing to the observable paramMap...
this._route.paramMap.pipe(
switchMap((params: ParamMap) => this._entityId = params.get('id'))
);
// Or as an alternative, with slightly different execution...
this._route.paramMap.subscribe((params: ParamMap) => {
this._entityId = params.get('id');
});
}
I prefer to use both because then on direct page load I can get the ID param, and also if navigating between related entities the subscription will update properly.
In the past months, I used a "preview" version of Android Studio. I tried to switch back to the "stable" releases for the software updates but it wasn't enough and I got this famous error you talk of.
Uninstalling my Android Studio 2.2.preview and installing latest stable Android Studio (2.1) fixed it for me :)
The way I would do similar thing is:
@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
@Profile ("client_app_profile_name")
public class ClientAppConfiguration {
//it can be left blank
}
Write similar one for the server app (without excludes).
Last step is to disable Auto Configuration from main spring boot class:
@SpringBootApplication
public class SomeApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SomeApplication.class);
}
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SomeApplication.class);
}
}
Change: @SpringBootApplication
into:
@Configuration
@ComponentScan
This should do the job. Now, the dependencies that I excluded in the example might be incomplete. They were enough for me, but im not sure if its all to completely disable database related libraries. Check the list below to be sure:
Hope that helps
When using TypeScript, the default tab width is always two regardless of what it says in the toolbar. You have to set "prettier.tabWidth" in your user settings to change it.
Ctrl + P, Type ? user settings, add:
"prettier.tabWidth": 4
Just remove

<deny users="?"/>
</authorization>

when iserting into t-sql
this fails:
select CONVERT(datetime,'2019-09-13 09:04:35.823312',21)
this works:
select CONVERT(datetime,'2019-09-13 09:04:35.823',21)
easy way:
regexp = re.compile(r'\.(\d{6})')
def to_splunk_iso(dt):
"""Converts the datetime object to Splunk isoformat string."""
# 6-digits string.
microseconds = regexp.search(dt).group(1)
return regexp.sub('.%d' % round(float(microseconds) / 1000), dt)
Another way is to use TRANSLATE:
TRANSLATE (col_name, 'x'||CHR(10)||CHR(13), 'x')
The 'x' is any character that you don't want translated to null, because TRANSLATE doesn't work right if the 3rd parameter is null.
I wrote this and placed it in a test/utils
module in my project. For cases when its not a class, just plan ol' dict, this will traverse both objects and ensure
Its big... its not sexy... but oh boi does it work!
def assertObjectsEqual(obj_a, obj_b):
def _assert(a, b):
if a == b:
return
raise AssertionError(f'{a} !== {b} inside assertObjectsEqual')
def _check(a, b):
if a is None or b is None:
_assert(a, b)
for k,v in a.items():
if isinstance(v, dict):
assertObjectsEqual(v, b[k])
else:
_assert(v, b[k])
# Asserting both directions is more work
# but it ensures no dangling values on
# on either object
_check(obj_a, obj_b)
_check(obj_b, obj_a)
You can clean it up a little by removing the _assert
and just using plain ol' assert
but then the message you get when it fails is very unhelpful.

Not a very good solution but one way is to redirect from the ROOT app to YourWebApp. For this you need to modify the ROOT index.html.

</html>
OR

Arrays have an implicit member variable holding the length:
for(int i=0; i<myArray.length; i++) {
System.out.println(myArray[i]);
}
Alternatively if using >=java5, use a for each loop:
for(Object o : myArray) {
System.out.println(o);
}
To make a custom "browse button" solution simply try making a hidden browse button, a custom button or element and some Jquery. This way I'm not modifying the actual "browse button" which is dependent on each browser/version. Here's an example.
HTML:
<div id="import" type="file">My Custom Button</div>
<input id="browser" class="hideMe" type="file"></input>
CSS:
#import {
margin: 0em 0em 0em .2em;
content: 'Import Settings';
display: inline-block;
border: 1px solid;
border-color: #ddd #bbb #999;
border-radius: 3px;
padding: 5px 8px;
outline: none;
white-space: nowrap;
-webkit-user-select: none;
cursor: pointer;
font-weight: 700;
font: bold 12px/1.2 Arial,sans-serif !important;
/* fallback */
background-color: #f9f9f9;
/* Safari 4-5, Chrome 1-9 */
background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#C2C1C1), to(#2F2727));
}
.hideMe{
display: none;
}
JS:
$("#import").click(function() {
$("#browser").trigger("click");
$('#browser').change(function() {
alert($("#browser").val());
});
});
I realize this question is old, but it recently popped up in a search I just ran, so I thought I'd post an alternative to the above answer.
If you are looking to generate create
scripts programmatically in .Net, I would highly recommend looking into Server Management Objects (SMO) or Distributed Management Objects (DMO) -- depending on which version of SQL Server you are using (the former is 2005+, the latter 2000). Using these libraries, scripting a table is as easy as:
Server server = new Server(".");
Database northwind = server.Databases["Northwind"];
Table categories = northwind.Tables["Categories"];
StringCollection script = categories.Script();
string[] scriptArray = new string[script.Count];
script.CopyTo(scriptArray, 0);
Here is a blog post with more information.
As of the 0.17.0 release, the sort
method was deprecated in favor of sort_values
. sort
was completely removed in the 0.20.0 release. The arguments (and results) remain the same:
df.sort_values(['a', 'b'], ascending=[True, False])
You can use the ascending argument of sort
:
df.sort(['a', 'b'], ascending=[True, False])
For example:
In [11]: df1 = pd.DataFrame(np.random.randint(1, 5, (10,2)), columns=['a','b'])
In [12]: df1.sort(['a', 'b'], ascending=[True, False])
Out[12]:
a b
2 1 4
7 1 3
1 1 2
3 1 2
4 3 2
6 4 4
0 4 3
9 4 3
5 4 1
8 4 1
As commented by @renadeen
Sort isn't in place by default! So you should assign result of the sort method to a variable or add inplace=True to method call.
that is, if you want to reuse df1 as a sorted DataFrame:
df1 = df1.sort(['a', 'b'], ascending=[True, False])
or
df1.sort(['a', 'b'], ascending=[True, False], inplace=True)
I think that it is the Environment error,you should try setting : DJANGO_SETTINGS_MODULE='correctly_settings'
I'd just like to add to Jon's example. To get a reference to your own assembly, you can use:
Assembly myAssembly = Assembly.GetExecutingAssembly();
System.Reflection
namespace.
If you want to examine an assembly that you have no reference to, you can use either of these:
Assembly assembly = Assembly.ReflectionOnlyLoad(fullAssemblyName);
Assembly assembly = Assembly.ReflectionOnlyLoadFrom(fileName);
If you intend to instantiate your type once you've found it:
Assembly assembly = Assembly.Load(fullAssemblyName);
Assembly assembly = Assembly.LoadFrom(fileName);
See the Assembly class documentation for more information.
Once you have the reference to the Assembly
object, you can use assembly.GetTypes()
like Jon already demonstrated.
For example:
you can use:
df %>% filter(!is.na(a))
to remove the NA in column a.
adb uninstall <package_name>
can be used to uninstall an app via your PC. If you want this to happen automatically every time you launch your app via Android Studio, you can do this:
adb
in Program: and uninstall <your-package-name>
in Parameters:.
Make sure that the new item is selected when you click Ok in the popup window.Note: If you do not have adb in your PATH environment variable, give the full path to adb in Program: field (eg /home/user/android/sdk/platform-tools/adb).
Android MediaPlayer doesn't support streaming of MP3 natively until 2.2. In older versions of the OS it appears to only stream 3GP natively. You can try the pocketjourney code, although it's old (there's a new version here) and I had trouble making it sticky — it would stutter whenever it refilled the buffer.
The NPR News app for Android is open source and uses a local proxy server to handle MP3 streaming in versions of the OS before 2.2. You can see the relevant code in lines 199-216 (r94) here: http://code.google.com/p/npr-android-app/source/browse/Npr/src/org/npr/android/news/PlaybackService.java?r=7cf2352b5c3c0fbcdc18a5a8c67d836577e7e8e3
And this is the StreamProxy class: http://code.google.com/p/npr-android-app/source/browse/Npr/src/org/npr/android/news/StreamProxy.java?r=e4984187f45c39a54ea6c88f71197762dbe10e72
The NPR app is also still getting the "error (-38, 0)" sometimes while streaming. This may be a threading issue or a network change issue. Check the issue tracker for updates.
You need to have
#include <string>
in the header file too.The forward declaration on it's own doesn't do enough.
Also strongly consider header guards for your header files to avoid possible future problems as your project grows. So at the top do something like:
#ifndef THE_FILE_NAME_H
#define THE_FILE_NAME_H
/* header goes in here */
#endif
This will prevent the header file from being #included multiple times, if you don't have such a guard then you can have issues with multiple declarations.
If you want to know if a property exists in an instance of a class that you have defined, simply combine property_exists()
with isset()
.
public function hasProperty($property)
{
return property_exists($this, $property) && isset($this->$property);
}
You can achieve this by controlling the formatting of the old/new/unchanged lines in GNU diff
output:
diff --new-line-format="" --unchanged-line-format="" file1 file2
The input files should be sorted for this to work. With bash
(and zsh
) you can sort in-place with process substitution <( )
:
diff --new-line-format="" --unchanged-line-format="" <(sort file1) <(sort file2)
In the above new and unchanged lines are suppressed, so only changed (i.e. removed lines in your case) are output. You may also use a few diff
options that other solutions don't offer, such as -i
to ignore case, or various whitespace options (-E
, -b
, -v
etc) for less strict matching.
Explanation
The options --new-line-format
, --old-line-format
and --unchanged-line-format
let you control the way diff
formats the differences, similar to printf
format specifiers. These options format new (added), old (removed) and unchanged lines respectively. Setting one to empty "" prevents output of that kind of line.
If you are familiar with unified diff format, you can partly recreate it with:
diff --old-line-format="-%L" --unchanged-line-format=" %L" \
--new-line-format="+%L" file1 file2
The %L
specifier is the line in question, and we prefix each with "+" "-" or " ", like diff -u
(note that it only outputs differences, it lacks the ---
+++
and @@
lines at the top of each grouped change).
You can also use this to do other useful things like number each line with %dn
.
The diff
method (along with other suggestions comm
and join
) only produce the expected output with sorted input, though you can use <(sort ...)
to sort in place. Here's a simple awk
(nawk) script (inspired by the scripts linked-to in Konsolebox's answer) which accepts arbitrarily ordered input files, and outputs the missing lines in the order they occur in file1.
# output lines in file1 that are not in file2
BEGIN { FS="" } # preserve whitespace
(NR==FNR) { ll1[FNR]=$0; nl1=FNR; } # file1, index by lineno
(NR!=FNR) { ss2[$0]++; } # file2, index by string
END {
for (ll=1; ll<=nl1; ll++) if (!(ll1[ll] in ss2)) print ll1[ll]
}
This stores the entire contents of file1 line by line in a line-number indexed array ll1[]
, and the entire contents of file2 line by line in a line-content indexed associative array ss2[]
. After both files are read, iterate over ll1
and use the in
operator to determine if the line in file1 is present in file2. (This will have have different output to the diff
method if there are duplicates.)
In the event that the files are sufficiently large that storing them both causes a memory problem, you can trade CPU for memory by storing only file1 and deleting matches along the way as file2 is read.
BEGIN { FS="" }
(NR==FNR) { # file1, index by lineno and string
ll1[FNR]=$0; ss1[$0]=FNR; nl1=FNR;
}
(NR!=FNR) { # file2
if ($0 in ss1) { delete ll1[ss1[$0]]; delete ss1[$0]; }
}
END {
for (ll=1; ll<=nl1; ll++) if (ll in ll1) print ll1[ll]
}
The above stores the entire contents of file1 in two arrays, one indexed by line number ll1[]
, one indexed by line content ss1[]
. Then as file2 is read, each matching line is deleted from ll1[]
and ss1[]
. At the end the remaining lines from file1 are output, preserving the original order.
In this case, with the problem as stated, you can also divide and conquer using GNU split
(filtering is a GNU extension), repeated runs with chunks of file1 and reading file2 completely each time:
split -l 20000 --filter='gawk -f linesnotin.awk - file2' < file1
Note the use and placement of -
meaning stdin
on the gawk
command line. This is provided by split
from file1 in chunks of 20000 line per-invocation.
For users on non-GNU systems, there is almost certainly a GNU coreutils package you can obtain, including on OSX as part of the Apple Xcode tools which provides GNU diff
, awk
, though only a POSIX/BSD split
rather than a GNU version.
There is a another way also
<div id="loadhtml"></div>
step 3: in Any Controller
var htmlcontent = $('#loadhtml ');
htmlcontent.load('/Pages/Common/contact.html')
$compile(htmlcontent.contents())($scope);
This Will Load a html page in Current page
This is just for my reference as what I was trying to achieve can be accomplished by this.
In the module.js
We can do something like this
module.exports = function ( firstArg, secondArg ) {
function firstFunction ( ) { ... }
function secondFunction ( ) { ... }
function thirdFunction ( ) { ... }
return { firstFunction: firstFunction, secondFunction: secondFunction,
thirdFunction: thirdFunction };
}
In the main.js
var name = require('module')(firstArg, secondArg);
To create an option that needs no value, set the action
[docs] of it to 'store_const'
, 'store_true'
or 'store_false'
.
Example:
parser.add_argument('-s', '--simulate', action='store_true')
Faced to this issue after a long time since question asked here. when checking material-ui code I found it's now accessible through inputRef
property.
...
<CssTextField
inputRef={(c) => {this.myRefs.username = c}}
label="Username"
placeholder="xxxxxxx"
margin="normal"
className={classes.textField}
variant="outlined"
fullWidth
/>
...
Then Access value like this.
onSaveUser = () => {
console.log('Saving user');
console.log(this.myRefs.username.value);
}
I had the same problem while trying to read the data from the request body. In my case which occurs randomly only to the mobile-based client devices. So I have increased the connectionUploadTimeout

This has changed for Visual Studio 2012 (I know the original question says VS2010, but the title will still hit on searches).
When you create a VS2012 MVC project, the system.web.mvc is placed in the packages folder which is peer to the solution. This will be referenced in the web project by default and you can find the exact path there).
If you want to reference this in a secondary project (say a supporting .dll with filters or other attributes), then you can reference it from there.
System wide C++ change on Ubuntu:

For Oracle SQL Developer I was able to calculate the difference in years using the below line of SQL. This was to get Years that were within 0 to 10 years difference. You can do a case like shown in some of the other responses to handle your ifs as well. Happy Coding!
TRUNC((MONTHS_BETWEEN(<DATE_ONE>, <DATE_TWO>) * 31) / 365) > 0 and TRUNC((MONTHS_BETWEEN(<DATE_ONE>, <DATE_TWO>) * 31) / 365) < 10
when(dao.doSearch(dto)).thenReturn(inspectionsSummaryList);//got error in this line
verify(dao).doSearchInspections(dto);
The when
here configures your mock to do something. However, you donot use this mock in any way anymore after this line (apart from doing a verify
). Mockito warns you that the when
line therefore is pointless. Perhaps you made a logic error?
Did you try -v
(or --verbose
) option for git commit
? It adds the diff of the commit in the message editor.
Can also see here on how to turn on MSDTC from the Control Panel's services.msc.
On the server where the trigger resides, you need to turn the MSDTC service on. You can this by clicking START > SETTINGS > CONTROL PANEL > ADMINISTRATIVE TOOLS > SERVICES. Find the service called 'Distributed Transaction Coordinator' and RIGHT CLICK (on it and select) > Start.
Old way:
SELECT DATE_COLUMN + 1 is adding a day
SELECT DATE_COLUMN + N /24 to add hour(s) - N being number of hours
SELECT DATE_COLUMN + N /1440 to add minute(s) - N being number of minutes
SELECT DATE_COLUMN + N /86400 to add second(s) - N being number of seconds
Using INTERVAL:
SELECT DATE_COLUMN + INTERVAL 'N' HOUR or MINUTE or SECOND - N being a number of hours or minutes or seconds.

Regarding your Update.
The concept of CRUD I believe has caused some confusion regarding API design. CRUD is a general low level concept for basic operations to perform on data, and HTTP verbs are just request methods (created 21 years ago) that may or may not map to a CRUD operation. In fact, try to find the presence of the CRUD acronym in the HTTP 1.0/1.1 specification.
A very well explained guide that applies a pragmatic convention can be found in the Google cloud platform API documentation. It describes the concepts behind the creation of a resource based API, one that emphasizes a big amount of resources over operations, and includes the use cases that you are describing. Although is a just a convention design for their product, I think it makes a lot of sense.
The base concept here (and one that produces a lot of confusion) is the mapping between "methods" and HTTP verbs. One thing is to define what "operations" (methods) your API will do over which types of resources (for example, get a list of customers, or send an email), and another are the HTTP verbs. There must be a definition of both, the methods and the verbs that you plan to use and a mapping between them.
It also says that, when an operation does not map exactly with a standard method (List
, Get
, Create
, Update
, Delete
in this case), one may use "Custom methods", like BatchGet
, which retrieves several objects based on several object id input, or SendEmail
.
For displaying Toast use the following code:
Toast toast = new Toast(getApplicationContext());

You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.
You can get the Java EE Edition of eclipse with has it pre-installed.
To create and run your first servlet:
doGet()
method.That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.
It is correct that set nowrap will allow you to paste in a long line without vi/vim adding newlines, but then the line is not visually wrapped for easy reading. It is instead just one long line that you have to scroll through.
To have the line visually wrap but not have newline characters inserted into it, have set wrap (which is probably default so not needed to set) and set textwidth=0.
On some systems the setting of textwidth=0 is default. If you don't find that to be the case, add set textwidth=0 to your .exrc file so that it becomes your user's default for all vi/vim sessions.
You need to use the __getitem__
method.
class MyClass:
def __getitem__(self, key):
return key * 2
myobj = MyClass()
myobj[3] #Output: 6
And if you're going to be setting values you'll need to implement the __setitem__
method too, otherwise this will happen:
>>> myobj[5] = 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: MyClass instance has no attribute '__setitem__'
I've used a few CSS hacks and targeted Chrome/Safari/Firefox/IE individually, as each browser renders selects a bit differently. I've tested on all browsers except IE.
For Safari/Chrome, set the height
and line-height
you want for your <select />
.
For Firefox, we're going to kill Firefox's default padding and border, then set our own. Set padding to whatever you like.
For IE 8+, just like Chrome, we've set the height
and line-height
properties. These two media queries
can be combined. But I kept it separate for demo purposes. So you can see what I'm doing.
Please note, for the height/line-height
property to work in Chrome/Safari OSX, you must set the background
to a custom value. I changed the color in my example.
Here's a jsFiddle of the below: http://jsfiddle.net/URgCB/4/
For the non-hack route, why not use a custom select plug-in via jQuery? Check out this: http://codepen.io/wallaceerick/pen/ctsCz
HTML:
<select>
<option>Here's one option</option>
<option>here's another option</option>
</select>
CSS:
@media screen and (-webkit-min-device-pixel-ratio:0) { /*safari and chrome*/
select {
height:30px;
line-height:30px;
background:#f4f4f4;
}
}
select::-moz-focus-inner { /*Remove button padding in FF*/
border: 0;
padding: 0;
}
@-moz-document url-prefix() { /* targets Firefox only */
select {
padding: 15px 0!important;
}
}
@media screen\0 { /* IE Hacks: targets IE 8, 9 and 10 */
select {
height:30px;
line-height:30px;
}
}
I've not looked into this but shooting from the hip I'd say that they dropped command line support in the portable. The reason people don't do much command line stuff in portable applications is that the OS (windows in your case) requires that executables be added to the %path% inclusion list.
If that requirement is not met using command line utilities is rather tedious.
7z -a .
would be
d:\portable\z7\z7 -a c:\to\archive\folder*.*
Typing that out for everything is why GUI's make sense with things like portable apps it (the app) can remember it's own location and handle that stuff for you and if you can't run it you know it's not attached.
If you really want the portable app to contain that though you can always install the full version and pull the required 7z.exe out and put it into the portable folder making sure it's in with the required dll's.
You'll have to set your path when you hit the shell after making sure it's attached.
http://www.redfernplace.com/software-projects/patheditor/ -- a good path editor (down) usefull if you have lots of path information 20+ get's hard to read.
http://www.softpedia.com/get/System/System-Miscellaneous/Path-Editor.shtml -- alternet source for path editor
It's not advisable to modify your system path for temproary "portable" drives though manualy do that by:
set path=%path%;"d:\portable\z7\";
when you run dos cmd.exe or http://sourceforge.net/p/conemu/home/Home/
The other answers address other problems better I'm not going to try..

PS: sorry for the necro but I figured it needed a more direct answer to why (even if it's just speculative).
I edit Mark Rajcok's focusMe directive to work for multiple focus in one element.
HTML:
<input focus-me="myInputFocus" type="text">
in AngularJs Controller:
$scope.myInputFocus= true;
AngulaJS Directive:
app.directive('focusMe', function ($timeout, $parse) {
return {
link: function (scope, element, attrs) {
var model = $parse(attrs.focusMe);
scope.$watch(model, function (value) {
if (value === true) {
$timeout(function () {
scope.$apply(model.assign(scope, false));
element[0].focus();
}, 30);
}
});
}
};
});
I solved it by creating a user in MySQL for the container's ip:
$ sudo mysql<br>
mysql> create user 'username'@'172.17.0.2' identified by 'password';<br>
Query OK, 0 rows affected (0.00 sec)
mysql> grant all privileges on database_name.* to 'username'@'172.17.0.2' with grant option;<br>
Query OK, 0 rows affected (0.00 sec)
$ sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
<br>bind-address = 172.17.0.1
$ sudo systemctl restart mysql.service
Then on container: jdbc:mysql://<b>172.17.0.1</b>:3306/database_name
This is already in :
Age from Date of Birth using JQuery
or alternatively u can use Date.parse() as in
var date1 = new Date("10/25/2011");
var date2 = new Date("09/03/2010");
var date3 = new Date(Date.parse(date1) - Date.parse(date2));
In your case you need map, since there is only 1 input and 1 output.
map - supplied function simply accepts an item and returns an item which will be emitted further (only once) down.
flatMap - supplied function accepts an item then returns an "Observable", meaning each item of the new "Observable" will be emitted separately further down.
May be code will clear things up for you:
Observable.just("item1").map( str -> {
System.out.println("inside the map " + str);
return str;
}).subscribe(System.out::println);
Observable.just("item2").flatMap( str -> {
System.out.println("inside the flatMap " + str);
return Observable.just(str + "+", str + "++" , str + "+++");
}).subscribe(System.out::println);
Output:
inside the map item1
item1
inside the flatMap item2
item2+
item2++
item2+++
Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.
Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:
/link/mybackend/?field1=value1&field2=value2&field3=value3
and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET
.
So your urlconf would be:
url(r'^link/(?P<backend>\w+?)/$', my_function)
and the view would look like:
def my_function(request, backend):
data = request.GET
and the reverse would be (after importing urllib
):
return "%s?%s" % (redirect('my_function', args=(backend,)),
urllib.urlencode(form.cleaned_data))
Edited after comment
The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.
If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.
That said, if all you want to do is store the data, then just put it in the session:
request.session['temp_data'] = form.cleaned_data
You have to specify the projectBaseDir
if the module name doesn't match you module directory.
Since both your module are located in ".", you can simply add the following to your sonar-project properties:
module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.
Sonar will handle your modules as components of the project:
EDIT
If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions
:
module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*
module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*
Using the Reflection in Java you can access all the private/public
fields and methods of one class to another .But as per the Oracle documentation in the section drawbacks they recommended that :
"Since reflection allows code to perform operations that would be illegal in non-reflective code, such as accessing private fields and methods, the use of reflection can result in unexpected side-effects, which may render code dysfunctional and may destroy portability. Reflective code breaks abstractions and therefore may change behavior with upgrades of the platform"
here is following code snapts to demonstrate basic concepts of Reflection
Reflection1.java
public class Reflection1{
private int i = 10;
public void methoda()
{
System.out.println("method1");
}
public void methodb()
{
System.out.println("method2");
}
public void methodc()
{
System.out.println("method3");
}
}
Reflection2.java
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class Reflection2{
public static void main(String ar[]) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException
{
Method[] mthd = Reflection1.class.getMethods(); // for axis the methods
Field[] fld = Reflection1.class.getDeclaredFields(); // for axis the fields
// Loop for get all the methods in class
for(Method mthd1:mthd)
{
System.out.println("method :"+mthd1.getName());
System.out.println("parametes :"+mthd1.getReturnType());
}
// Loop for get all the Field in class
for(Field fld1:fld)
{
fld1.setAccessible(true);
System.out.println("field :"+fld1.getName());
System.out.println("type :"+fld1.getType());
System.out.println("value :"+fld1.getInt(new Reflaction1()));
}
}
}
Hope it will help.
Last-Modified : The last modified date for the requested object
If-Modified-Since : Allows a 304 Not Modified to be returned if last modified date is unchanged.
ETag : An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned.
If-None-Match : Allows a 304 Not Modified to be returned if ETag is unchanged.
the browser store cache with a date(Last-Modified) or id(ETag), when you need to request the URL again, the browser send request message with the header:
the server will return 304 when the if statement is False, and browser will use cache.
I found a much simpler alternative way to generating soap message. Given a Person Object:
import com.fasterxml.jackson.annotation.JsonInclude;
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Person {
private String name;
private int age;
private String address; //setter and getters below
}
Below is a simple Soap Message Generator:
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
@Slf4j
public class SoapGenerator {
protected static final ObjectMapper XML_MAPPER = new XmlMapper()
.enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL)
.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
.registerModule(new JavaTimeModule());
private static final String SOAP_BODY_OPEN = "<soap:Body>";
private static final String SOAP_BODY_CLOSE = "</soap:Body>";
private static final String SOAP_ENVELOPE_OPEN = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
private static final String SOAP_ENVELOPE_CLOSE = "</soap:Envelope>";
public static String soapWrap(String xml) {
return SOAP_ENVELOPE_OPEN + SOAP_BODY_OPEN + xml + SOAP_BODY_CLOSE + SOAP_ENVELOPE_CLOSE;
}
public static String soapUnwrap(String xml) {
return StringUtils.substringBetween(xml, SOAP_BODY_OPEN, SOAP_BODY_CLOSE);
}
}
You can use by:
public static void main(String[] args) throws Exception{
Person p = new Person();
p.setName("Test");
p.setAge(12);
String xml = SoapGenerator.soapWrap(XML_MAPPER.writeValueAsString(p));
log.info("Generated String");
log.info(xml);
}
Already answered above, but here's another approach you could take. I can't find the original post I adapted this from, but here's the code for the sake of your question. As noted above, the flatMap() function is what you'd be looking to utilize with Java 8. You can throw it in a utility class and just call "RandomUtils.combine(list1, list2, ...);" and you'd get a single List with all values. Just be careful with the wildcard - you could change this if you want a less generic method. You can also modify it for Sets - you just have to take care when using flatMap() on Sets to avoid data loss from equals/hashCode methods due to the nature of the Set interface.
Edit - If you use a generic method like this for the Set interface, and you happen to use Lombok, make sure you understand how Lombok handles equals/hashCode generation.
/**
* Combines multiple lists into a single list containing all elements of
* every list.
*
* @param <T> - The type of the lists.
* @param lists - The group of List implementations to combine
* @return a single List<?> containing all elements of the passed in lists.
*/
public static <T> List<?> combine(final List<?>... lists) {
return Stream.of(lists).flatMap(List::stream).collect(Collectors.toList());
}
Here is a pitfall to avoid. In case you need to access your variable $name within a function, you need to say "global $name;" at the beginning of that function. You need to repeat this for each function in the same file.
include('front.inc');
global $name;
function foo() {
echo $name;
}
function bar() {
echo $name;
}
foo();
bar();
will only show errors. The correct way to do that would be:
include('front.inc');
function foo() {
global $name;
echo $name;
}
function bar() {
global $name;
echo $name;
}
foo();
bar();
To retrieve the height of the ActionBar in XML, just use
?android:attr/actionBarSize
or if you're an ActionBarSherlock or AppCompat user, use this
?attr/actionBarSize
If you need this value at runtime, use this
final TypedArray styledAttributes = getContext().getTheme().obtainStyledAttributes(
new int[] { android.R.attr.actionBarSize });
mActionBarSize = (int) styledAttributes.getDimension(0, 0);
styledAttributes.recycle();
If you need to understand where this is defined:
Enter "#!/bin/sh"
before script.
Then save it as script.sh
for example.
copy it to $HOME/bin
or $HOME/usr/bin
The directory can be different on different linux distros but they end with 'bin'
and are in home directory
cd $HOME/bin
or $HOME/usr/bin
Type chmod 700 script.sh
And you can run it just by typing run.sh
on terminal.
If it not work, try chmod +x run.sh
instead of chmod 700 run.sh
You can try this
SELECT tbl.* FROM (SELECT * FROM table ORDER BY timestamp DESC) as tbl
GROUP BY tbl.m_id
An improvement on Theodor Zoulias's nice multi-core Parallel.ForEach implementation:
public static ulong SumToUlongPar(this uint[] arrayToSum, int startIndex, int length, int degreeOfParallelism = 0)
{
var concurrentSums = new ConcurrentBag<ulong>();
int maxDegreeOfPar = degreeOfParallelism <= 0 ? Environment.ProcessorCount : degreeOfParallelism;
var options = new ParallelOptions() { MaxDegreeOfParallelism = maxDegreeOfPar };
Parallel.ForEach(Partitioner.Create(startIndex, startIndex + length), options, range =>
{
ulong localSum = 0;
for (int i = range.Item1; i < range.Item2; i++)
localSum += arrayToSum[i];
concurrentSums.Add(localSum);
});
ulong sum = 0;
var sumsArray = concurrentSums.ToArray();
for (int i = 0; i < sumsArray.Length; i++)
sum += sumsArray[i];
return sum;
}
which works for unsigned integer data types, since C# only support Interlocked.Add() for int and long. The above implementation can also be easily modified to support other integer and floating-point data types to do summation in parallel using multiple cores of the CPU. It is used in the HPCsharp nuget package.
I think so.. it's possible to 'bind' custom events, like(from: http://docs.jquery.com/Events/bind#typedatafn):
$("p").bind("myCustomEvent", function(e, myName, myValue){
$(this).text(myName + ", hi there!");
$("span").stop().css("opacity", 1)
.text("myName = " + myName)
.fadeIn(30).fadeOut(1000);
});
$("button").click(function () {
$("p").trigger("myCustomEvent", [ "John" ]);
});
I disabled all installed extensions in Chrome - works for me. I have now clear console without errors.
I stumbled across this attempting to solve the same issue. The installation I am working with uses JBOSS and Hibernate, so I had to do this a different way. For the basic case, you should be able to add zeroDateTimeBehavior=convertToNull
to your connection URI as per this configuration properties page.
I found other suggestions across the land referring to putting that parameter in your hibernate config:
In hibernate.cfg.xml:
<property name="hibernate.connection.zeroDateTimeBehavior">convertToNull</property>
In hibernate.properties:
hibernate.connection.zeroDateTimeBehavior=convertToNull
But I had to put it in my mysql-ds.xml file for JBOSS as:
<connection-property name="zeroDateTimeBehavior">convertToNull</connection-property>
Hope this helps someone. :)
I'm doing it like this:
Models are ViewScoped
converter:
@Named
@ViewScoped
public class ViewScopedFacesConverter implements Converter, Serializable
{
private static final long serialVersionUID = 1L;
private Map<String, Object> converterMap;
@PostConstruct
void postConstruct(){
converterMap = new HashMap<>();
}
@Override
public String getAsString(FacesContext context, UIComponent component, Object object) {
String selectItemValue = String.valueOf( object.hashCode() );
converterMap.put( selectItemValue, object );
return selectItemValue;
}
@Override
public Object getAsObject(FacesContext context, UIComponent component, String selectItemValue){
return converterMap.get(selectItemValue);
}
}
and bind to component with:
<f:converter binding="#{viewScopedFacesConverter}" />
If you will use entity id rather than hashCode you can hit a collision- if you have few lists on one page for different entities (classes) with the same id
This code
var title = news.title;
var link = news.link;
arr.push({title : link});
is not doing what you think it does. What gets pushed is a new object with a single member named "title" and with link
as the value ... the actual title
value is not used.
To save an object with two fields you have to do something like
arr.push({title:title, link:link});
or with recent Javascript advances you can use the shortcut
arr.push({title, link}); // Note: comma "," and not colon ":"
If instead you want the key of the object to be the content of the variable title
you can use
arr.push({[title]: link}); // Note that title has been wrapped in brackets
You could use php to echo the browser name as a body
class, e.g.
<body class="mozilla">
Then, your conditional CSS would look like
.ie #container { top: 5px;}
.mozilla #container { top: 5px;}
.chrome #container { top: 5px;}
Either in SQL or in report code (as per adolf garlic's function suggestion)
At this moment in time, I'd do it in the report. I have very few reports against a busy OLTP server and an underwhelmed report server. If I had a different mix I'd do it in SQL.
Either way is acceptable...
