If you are running macOS X and run platform.system()
you get darwin
because macOS X is built on Apple's Darwin OS. Darwin is the kernel of macOS X and is essentially macOS X without the GUI.
Use osenv.home()
. It's maintained by isaacs and I believe is used by npm itself.
Adding to the other great answers, we can use the Python logging
library's debug()
, info()
, warning()
, error()
, and critical()
methods. Quoting from the docs for Python 3.7.4,
There are three keyword arguments in kwargs which are inspected: exc_info which, if it does not evaluate as false, causes exception information to be added to the logging message.
What this means is, you can use the Python logging
library to output a debug()
, or other type of message, and the logging
library will include the stack trace in its output. With this in mind, we can do the following:
import logging
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
def f():
a = { 'foo': None }
# the following line will raise KeyError
b = a['bar']
def g():
f()
try:
g()
except Exception as e:
logger.error(str(e), exc_info=True)
And it will output:
'bar'
Traceback (most recent call last):
File "<ipython-input-2-8ae09e08766b>", line 18, in <module>
g()
File "<ipython-input-2-8ae09e08766b>", line 14, in g
f()
File "<ipython-input-2-8ae09e08766b>", line 10, in f
b = a['bar']
KeyError: 'bar'
First follow this procedure:
Log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:
a@A:~> ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/a/.ssh/id_rsa):
Created directory '/home/a/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A
Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine):
a@A:~> ssh b@B mkdir -p .ssh
b@B's password:
Finally append a's new public key to b@B:.ssh/authorized_keys and enter b's password one last time:
a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
b@B's password:
From now on you can log into B as b from A as a without password:
a@A:~> ssh b@B
then this will work without entering a password
ssh b@B "cd /some/directory; program-to-execute &"
@qbzenker provided the most idiomatic method IMO

You must use an integer value for the CURLOPT_SSLVERSION
value, not a string as listed above
Try this:
curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 6); //Integer NOT string TLS v1.2

After spending many hours searching I found a very simple method, I found no example and so I share mine here which works with images. (mine was a .gif)
Summary:
It returns a BitmapFrame which ImageSource "destinations" seem to like.
Use:
doGetImageSourceFromResource ("[YourAssemblyNameHere]", "[YourResourceNameHere]");
Method:
static internal ImageSource doGetImageSourceFromResource(string psAssemblyName, string psResourceName)
{
Uri oUri = new Uri("pack://application:,,,/" +psAssemblyName +";component/" +psResourceName, UriKind.RelativeOrAbsolute);
return BitmapFrame.Create(oUri);
}
Learnings:
From my experiences the pack string is not the issue, check your streams and especially if reading it the first time has set the pointer to the end of the file and you need to re-set it to zero before reading again.
I hope this saves you the many hours I wish this piece had for me!
Most probably, you want something like this:
$("#list li").click(function() {
var selected = $(this).html();
alert(selected);
});
You can't expect ObjectInputStream
to automagically convert text into objects. The hexadecimal 54657374
is "Test"
as text. You must be sending it directly as bytes.
If you are trying to get an index based on a predicate, try this:
If you only care about the first index:
OptionalInt index = IntStream.range(0, list.size())
.filter(i -> list.get(i) == 3)
.findFirst();
Or if you want to find multiple indexes:
IntStream.range(0, list.size())
.filter(i -> list.get(i) == 3)
.collect(Collectors.toList());
Add .orElse(-1);
in case you want to return a value if it doesn't find it.
if re.match(regex, content):
blah..
You could also use re.search
depending on how you want it to match.
What do you actually want to achieve? What your code does is it tries to connect to a server located at 192.168.1.104:4000
. Is this the address of a server that sends the messages (because this looks like a client-side code)? If I run fake server locally:
$ nc -l 4000
...and change socket address to localhost:4000
, it will work and try to read something from nc
-created server.
ServerSocket
and listen on it:ServerSocket serverSocket = new ServerSocket(4000);
Socket socket = serverSocket.accept();
The second line will block until some other piece of software connects to your machine on port 4000. Then you can read from the returned socket. Look at this tutorial, this is actually a very broad topic (threading, protocols...)
They are user-defined signals, so they aren't triggered by any particular action. You can explicitly send them programmatically:
#include <signal.h>
kill(pid, SIGUSR1);
where pid
is the process id of the receiving process. At the receiving end, you can register a signal handler for them:
#include <signal.h>
void my_handler(int signum)
{
if (signum == SIGUSR1)
{
printf("Received SIGUSR1!\n");
}
}
signal(SIGUSR1, my_handler);
=(A1/86400)+25569
...and the format of the cell should be date.
#####
you probably don't have a real Unix time. Check your
timestamps in https://www.epochconverter.com/. Try to divide your input by 10, 100, 1000 or 10000**A1
with the cell containing the timestamp ;-pUnix system represent a point in time as a number. Specifically the number of seconds* since a zero-time called the Unix epoch which is 1/1/1970 00:00 UTC/GMT
. This number of seconds is called "Unix timestamp" or "Unix time" or "POSIX time" or just "timestamp" and sometimes (confusingly) "Unix epoch".
In the case of Excel they chose a different zero-time and step (because who wouldn't like variety in technical details?). So Excel counts days
since 24 hours before 1/1/0000 UTC/GMT
. So 25569 corresponds to 1/1/1970 00:00 UTC/GMT
and 25570 to 2/1/1970 00:00
.
Now please note that we have 86400 seconds per day (24 hours x60 minutes each x60 seconds) and you can understand what this formula does: A1/86400
converts seconds to days and +25569
adjusts for the offset between what is time-zero for Unix and what is time-zero for Excel.
By the way DATE(1970,1,1)
will helpfully return 25569 for you in case you forget all this so a more "self-documenting" way to write our formula is:
=A1/(24*60*60) + DATE(1970,1,1)
P.S.: All these were already present in other answers and comments just not laid out as I like them and I don't feel it's OK to edit the hell out of another answer.
*: that's almost correct because you should not count leap seconds
**: E.g. in the case of this question the number was number of milliseconds since the the Unix epoch.
You could probably write your own custom implementation of click/dblclick to have it wait for an extra click. I don't see anything in the core jQuery functions that would help you achieve this.
Quote from .dblclick() at the jQuery site
It is inadvisable to bind handlers to both the click and dblclick events for the same element. The sequence of events triggered varies from browser to browser, with some receiving two click events before the dblclick and others only one. Double-click sensitivity (maximum time between clicks that is detected as a double click) can vary by operating system and browser, and is often user-configurable.
In android gradle 0.4.0 you can just do:
println System.env.HOME
classpath com.android.tools.build:gradle-experimental:0.4.0
Use the following code to prepend a contentless first-child to the unintentionally moving div:
.parent:before
{content: '';position: relative;height: 0px;width: 0px;overflow: hidden;white-space: pre;}
The advantage of this method is that you do not need to change the CSS of any existing element, and therefore has minimal impact on design. Next to this, the element that is added is a pseudo-element, which is not in the DOM-tree.
Support for pseudo-elements is wide-spread: Firefox 3+, Safari 3+, Chrome 3+, Opera 10+, and IE 8+. This will work in any modern browser (be careful with the newer ::before
, which is not supported in IE8).
If the first child of an element has a margin-top
, the parent will adjust its position as a way of collapsing redundant margins. Why? It's just like that.
Given the following problem:
<style type="text/css">
div {position: relative;}
.parent {background-color: #ccc;}
.child {margin-top: 40px;}
</style>
<div class="parent"><!--This div moves 40px too-->
<div class="child">Hello world!</div>
</div>
You can fix it by adding a child with content, such as a simple space. But we all hate to add spaces for what is a design-only issue. Therefore, use the white-space
property to fake content.
<style type="text/css">
div {position: relative;}
.parent {background-color: #ccc;}
.child {margin-top: 40px;}
.fix {position: relative;white-space: pre;height: 0px;width: 0px;overflow: hidden;}
</style>
<div class="parent"><!--This div won't move anymore-->
<div class="fix"></div>
<div class="child">Hello world!</div>
</div>
Where position: relative;
ensures correct positioning of the fix. And white-space: pre;
makes you not having to add any content - like a white space - to the fix. And height: 0px;width: 0px;overflow: hidden;
makes sure you'll never see the fix.
You might need to add line-height: 0px;
or max-height: 0px;
to ensure the height is actually zero in ancient IE browsers (I'm unsure). And optionally you could add <!--dummy-->
to it in old IE browsers, if it does not work.
In short, you can do all this with only CSS (which removes the need to add an actual child to the HTML DOM-tree):
<style type="text/css">
div {position: relative;}
.parent {background-color: #ccc;}
.child {margin-top: 40px;}
.parent:before {content: '';position: relative;height: 0px;width: 0px;overflow: hidden;white-space: pre;}
</style>
<div class="parent"><!--This div won't move anymore-->
<div class="child">Hello world!</div>
</div>

date.setTime(date.getTime() + (days*24*60*60*1000));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + (value || "") + expires + "; path=/";
}
function getCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function eraseCookie(name) {
document.cookie = name +'=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;';

I also ran into the same challanged and ended up at this page. Although I am 11 years too late to answers the question, I thought maybe it could be still usefull for others. I found the answer of davidxxx
with Logback and the ListAppander very usefull. I used the same configuration for multiple projects, however it was not so fun to copy/paste it and maintaining all the version when I needed to changes something. I thought it would be better to make a library out of it and contribute back to the community. It works with SLFJ4, Log4j, Log4j2, Java Util Logging And with Lombok annotations. Please have a look here: LogCaptor
Example situation:
public class FooService {
private static final Logger LOGGER = LoggerFactory.getLogger(FooService.class);
public void sayHello() {
LOGGER.info("Keyboard not responding. Press any key to continue...");
LOGGER.warn("Congratulations, you are pregnant!");
}
}
Example unit test with usage of LogCaptor:
public class FooServiceTest {
private LogCaptor logCaptor = LogCaptor.forClass(FooService.class);
@Test
public void logInfoAndWarnMessages() {
String expectedInfoMessage = "Keyboard not responding. Press any key to continue...";
String expectedWarnMessage = "Congratulations, you are pregnant!";
FooService fooService = new FooService();
fooService.sayHello();
List<String> infoLogMessages = logCaptor.getInfoLogs();
List<String> warnLogMessages = logCaptor.getWarnLogs();
List<String> allLogMessages = logCaptor.getLogs();
assertThat(infoLogMessages).containsExactly(expectedInfoMessage);
assertThat(warnLogMessages).containsExactly(expectedWarnMessage);
assertThat(allLogMessages).containsExactly(expectedWarnMessage, expectedInfoMessage);
}
}
I wasn't quite sure if I should post this here, because it could also be seen as a way to promote "my library" but I thought it could be helpful for developers who have the same challenges.
To post JSON with jQuery in JavaScript, use JSON.stringify
to dump the data, and set the content type to application/json
.
var value_data = [1, 2, 3, 4];
$.ajax({
type: 'POST',
url: '/process',
data: JSON.stringify(value_data),
contentType: 'application/json',
success: function (response_data) {
alert("success");
}
});
Parse it in Flask with request.get_json()
.
data = request.get_json()
Try this:
<div class='content'>
@Html.Raw(HttpUtility.HtmlDecode(Model.Content))
</div>
border-radius: 50%;
will turn all elements into a circle, regardless of size. At least, as long as the height
and width
of the target are the same, otherwise it will turn into an oval.
#target{_x000D_
width: 100px;_x000D_
height: 100px;_x000D_
background-color: #aaa;_x000D_
border-radius: 50%;_x000D_
}
_x000D_
<div id="target"></div>
_x000D_
Note: browser prefixes are not needed anymore for border-radius
Alternatively, you can use clip-path: circle();
to turn an element into a circle as well. Even if the element has a greater width
than height
(or the other way around), it will still become a circle, and not an oval.
#target{_x000D_
width: 200px;_x000D_
height: 100px;_x000D_
background-color: #aaa;_x000D_
clip-path: circle();_x000D_
}
_x000D_
<div id="target"></div>
_x000D_
Note: clip-path is not (yet) supported by all browsers
You can place text inside of the circle, simply by writing the text inside of the tags of the target,
like so:
<div>text</div>
If you want to center text in the circle, you can do the following:
#target{_x000D_
width: 100px;_x000D_
height: 100px;_x000D_
background-color: #aaa;_x000D_
border-radius: 50%;_x000D_
_x000D_
display: flex;_x000D_
align-items: center;_x000D_
}_x000D_
_x000D_
#text{_x000D_
width: 100%;_x000D_
text-align: center;_x000D_
}
_x000D_
<div id="target">_x000D_
<div id="text">text</div>_x000D_
</div>
_x000D_
Cloud is a marketing term, with the bare minimum feature relating to fast automated provisioning of new servers. HA, utility billing, etc are all features people can lump on top to define it to their own liking.
Grid [Computing] is an extension of clusters where multiple loosely coupled systems are used to solve a single problem. They tend to be multi-tenant, sharing some likeness to Clouds, but tend to rely heavily upon custom frameworks that manage the interop between grid nodes.
Cluster hosting is a specialization of clusters where a load balancer is used to direct incoming traffic to one of many worker nodes. It predates grid computing and doesn't rely on a homogenous abstraction of the underlying nodes as much as Grid computing. A web farm tends to have very specialized machines dedicated to each component type and is far more optimized for that specific task.
For pure hosting, Grid computing is the wrong tool. If you have no idea what your traffic shape is, then a Cloud would be useful. For predictable usage that changes at a reasonable pace, then a traditional cluster is fine and the most efficient.
It does what you ask, SELECT 1 FROM table
will SELECT
(return) a 1
for every row in that table, if there were 3 rows in the table you would get
1

Take a look at Count(*) vs Count(1) which may be the issue you were described.
Short answer:
ALTER SCHEMA new_schema TRANSFER old_schema.table_name
I can confirm that the data in the table remains intact, which is probably quite important :)
Long answer as per MSDN docs,
ALTER SCHEMA schema_name
TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]
If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.
This is a quick solution in case you want to convert more columns of your pandas.DataFrame
from float to integer considering also the case that you can have NaN values.
cols = ['col_1', 'col_2', 'col_3', 'col_4']
for col in cols:
df[col] = df[col].apply(lambda x: int(x) if x == x else "")
I tried with else x)
and else None)
, but the result is still having the float number, so I used else ""
.
$ python -c "import os.path; print os.path.relpath('/foo/bar', '/foo/baz/foo')"
gives:
../../bar
You could also sidestep nested cursor issues, general cursor issues, and global variable issues by avoiding the cursors entirely.
declare @rowid int
declare @rowid2 int
declare @id int
declare @type varchar(10)
declare @rows int
declare @rows2 int
declare @outer table (rowid int identity(1,1), id int, type varchar(100))
declare @inner table (rowid int identity(1,1), clientid int, whatever int)
insert into @outer (id, type)
Select id, type from sometable
select @rows = count(1) from @outer
while (@rows > 0)
Begin
select top 1 @rowid = rowid, @id = id, @type = type
from @outer
insert into @innner (clientid, whatever )
select clientid whatever from contacts where contactid = @id
select @rows2 = count(1) from @inner
while (@rows2 > 0)
Begin
select top 1 /* stuff you want into some variables */
/* Other statements you want to execute */
delete from @inner where rowid = @rowid2
select @rows2 = count(1) from @inner
End
delete from @outer where rowid = @rowid
select @rows = count(1) from @outer
End

EDIT : It is not bleeding edge anymore : http://blog.docker.com/2016/02/docker-1-10/
Original Answer
I battled with it the whole night.
If you're not afraid of bleeding edge, the latest version of Docker engine and Docker compose both implement libnetwork.
With the right config file (that need to be put in version 2), you will create services that will all see each other. And, bonus, you can scale them with docker-compose as well (you can scale any service you want that doesn't bind port on the host)
Here is an example file
version: "2"
services:
router:
build: services/router/
ports:
- "8080:8080"
auth:
build: services/auth/
todo:
build: services/todo/
data:
build: services/data/
And the reference for this new version of compose file: https://github.com/docker/compose/blob/1.6.0-rc1/docs/networking.md
TypeError: Cannot read property 'then' of undefined when calling a Django service using AngularJS.
If you are calling a Python service, the code will look like below:
this.updateTalentSupplier=function(supplierObj){
var promise = $http({
method: 'POST',
url: bbConfig.BWS+'updateTalentSupplier/',
data:supplierObj,
withCredentials: false,
contentType:'application/json',
dataType:'json'
});
return promise; //Promise is returned
}
We are using MongoDB as the database(I know it doesn't matter. But if someone is searching with MongoDB + Python (Django) + AngularJS the result should come.
There also other ways to use the composer autoload features. Ways that can be useful to load packages without namespaces or packages that come with a custom autoload function.
For example if you want to include a single file that contains an autoload function as well you can use the "files" directive as follows:
"autoload": {
"psr-0": {
"": "src/",
"SymfonyStandard": "app/"
},
"files": ["vendor/wordnik/wordnik-php/wordnik/Swagger.php"]
},
And inside the Swagger.php
file we got:
function swagger_autoloader($className) {
$currentDir = dirname(__FILE__);
if (file_exists($currentDir . '/' . $className . '.php')) {
include $currentDir . '/' . $className . '.php';
} elseif (file_exists($currentDir . '/models/' . $className . '.php')) {
include $currentDir . '/models/' . $className . '.php';
}
}
spl_autoload_register('swagger_autoloader');
https://getcomposer.org/doc/04-schema.md#files
Otherwise you may want to use a classmap reference:
{
"autoload": {
"classmap": ["src/", "lib/", "Something.php"]
}
}
https://getcomposer.org/doc/04-schema.md#classmap
Note: during your tests remember to launch the composer dump-autoload
command or you won't see any change!
./composer.phar dump-autoload
Happy autoloading =)

Have a max int and set it to the first value in the array. Then in a for loop iterate through the whole array and see if the max int is larger than the int at the current index.
int max = array.get(0);
for (int i = 1; i < array.length; i++) {
if (array.get(i) > max) {
max = array.get(i);
}
}
Here is example:
You have a.bat:
@echo off
if exist b.bat goto RUNB
goto END
:RUNB
b.bat
:END
and b.bat called conditionally from a.bat:
@echo off
echo "This is b.bat"

Using requests and json makes it simple.
json.loads
functionRequests module provides you useful function to loop for success and failure.
if(Response.ok)
: will help help you determine if your API call is successful (Response code - 200)
Response.raise_for_status()
will help you fetch the http code that is returned from the API.
Below is a sample code for making such API calls. Also can be found in github. The code assumes that the API makes use of digest authentication. You can either skip this or use other appropriate authentication modules to authenticate the client invoking the API.
#Python 2.7.6
#RestfulClient.py
import requests
from requests.auth import HTTPDigestAuth
import json
# Replace with the correct URL
url = "http://api_url"
# It is a good practice not to hardcode the credentials. So ask the user to enter credentials at runtime
myResponse = requests.get(url,auth=HTTPDigestAuth(raw_input("username: "), raw_input("Password: ")), verify=True)
#print (myResponse.status_code)
# For successful API call, response code will be 200 (OK)
if(myResponse.ok):
# Loading the response data into a dict variable
# json.loads takes in only binary or string variables so using content to fetch binary content
# Loads (Load String) takes a Json file and converts into python data structure (dict or list, depending on JSON)
jData = json.loads(myResponse.content)
print("The response contains {0} properties".format(len(jData)))
print("\n")
for key in jData:
print key + " : " + jData[key]
else:
# If response code is not ok (200), print the resulting http error code with description
myResponse.raise_for_status()
This will make exactly what you were expecting:
Objective-C:
[myButton.titleLabel setTextAlignment:UITextAlignmentCenter];
For iOS 6 or higher it's
[myButton.titleLabel setTextAlignment: NSTextAlignmentCenter];

myButton.titleLabel?.textAlignment = NSTextAlignment.Center
Swift 4.x and above
myButton.titleLabel?.textAlignment = .center

I'm not sure what you're trying to do, but here's something to consider: c();
won't do anything. c
is an instance of the class checkbox
and not a method to be called. So consider this:
public class FirstWindow extends JFrame { public FirstWindow() { checkbox c = new checkbox(); c.yourMethod(yourParameters); // call the method you made in checkbox } } public class checkbox extends JFrame { public checkbox(yourParameters) { // this is the constructor method used to initialize instance variables } public void yourMethod() // doesn't have to be void { // put your code here } }
Is your server configured for client authentication? If so you need to pass the client certificate while connecting with the server.

I figured out how to use multiple left outer joins in VB.NET using LINQ to SQL:
Dim db As New ContractDataContext()
Dim query = From o In db.Orders _
Group Join v In db.Vendors _
On v.VendorNumber Equals o.VendorNumber _
Into ov = Group _
From x In ov.DefaultIfEmpty() _
Group Join s In db.Status _
On s.Id Equals o.StatusId Into os = Group _
From y In os.DefaultIfEmpty() _
Where o.OrderNumber >= 100000 And o.OrderNumber <= 200000 _
Select Vendor_Name = x.Name, _
Order_Number = o.OrderNumber, _
Status_Name = y.StatusName
gg=G
will reindent the entire file and removes most if not all the tabs I get in files from co-workers.
In Java there is nothing at language level similar to ref. In Java there is only passing by value semantic
For the sake of curiosity you can implement a ref-like semantic in Java simply wrapping your objects in a mutable class:
public class Ref<T> {
private T value;
public Ref(T value) {
this.value = value;
}
public T get() {
return value;
}
public void set(T anotherValue) {
value = anotherValue;
}
@Override
public String toString() {
return value.toString();
}
@Override
public boolean equals(Object obj) {
return value.equals(obj);
}
@Override
public int hashCode() {
return value.hashCode();
}
}
testcase:
public void changeRef(Ref<String> ref) {
ref.set("bbb");
}
// ...
Ref<String> ref = new Ref<String>("aaa");
changeRef(ref);
System.out.println(ref); // prints "bbb"

I used this to check if all the text boxes had numeric values:
if(!$.isNumeric($('input:text').val())) {
alert("All the text boxes must have numeric values!");
return false;
}
or for one:
$.isNumeric($("txtBox").val());
Available with jQuery 1.7.
This will select empty text inputs with an id that starts with "txt":
$(':text[value=""][id^=txt]')

I liked the solution from Ruidge, but I needed more control from XML. So I changed it to Kotlin and added attributes.
1) Copy the Kotlin class:
import android.content.Context
import android.graphics.*
import android.util.AttributeSet
import android.view.View
class DashedDividerView : View {
constructor(context: Context) : this(context, null, 0)
constructor(context: Context, attributeSet: AttributeSet) : this(context, attributeSet, 0)
companion object {
const val DIRECTION_VERTICAL = 0
const val DIRECTION_HORIZONTAL = 1
}
private var dGap = 5.25f
private var dWidth = 5.25f
private var dColor = Color.parseColor("#EE0606")
private var direction = DIRECTION_HORIZONTAL
private val paint = Paint()
private val path = Path()
constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int) : super(
context,
attrs,
defStyleAttr
) {
val typedArray = context.obtainStyledAttributes(
attrs,
R.styleable.DashedDividerView,
defStyleAttr,
R.style.DashedDividerDefault
)
dGap = typedArray.getDimension(R.styleable.DashedDividerView_dividerDashGap, dGap)
dWidth = typedArray.getDimension(R.styleable.DashedDividerView_dividerDashWidth, dWidth)
dColor = typedArray.getColor(R.styleable.DashedDividerView_dividerDashColor, dColor)
direction =
typedArray.getInt(R.styleable.DashedDividerView_dividerDirection, DIRECTION_HORIZONTAL)
paint.color = dColor
paint.style = Paint.Style.STROKE
paint.pathEffect = DashPathEffect(floatArrayOf(dWidth, dGap), 0f)
paint.strokeWidth = dWidth
typedArray.recycle()
}
override fun onDraw(canvas: Canvas) {
super.onDraw(canvas)
path.moveTo(0f, 0f)
if (direction == DIRECTION_HORIZONTAL) {
path.lineTo(measuredWidth.toFloat(), 0f)
} else {
path.lineTo(0f, measuredHeight.toFloat())
}
canvas.drawPath(path, paint)
}
}
2) Create an attr file in the /res directory and add this
<declare-styleable name="DashedDividerView">
<attr name="dividerDashGap" format="dimension" />
<attr name="dividerDashWidth" format="dimension" />
<attr name="dividerDashColor" format="reference|color" />
<attr name="dividerDirection" format="enum">
<enum name="vertical" value="0" />
<enum name="horizontal" value="1" />
</attr>
</declare-styleable>
3) Add a style to the styles file
<style name="DashedDividerDefault">
<item name="dividerDashGap">2dp</item>
<item name="dividerDashWidth">2dp</item>
<!-- or any color -->
<item name="dividerDashColor">#EE0606</item>
<item name="dividerDirection">horizontal</item>
</style>
4) Now you can use the default style
<!-- here will be your path to the class -->
<com.your.package.app.DashedDividerView
android:layout_width="match_parent"
android:layout_height="2dp"
/>
or set attributes in XML
<com.your.package.app.DashedDividerView
android:layout_width="match_parent"
android:layout_height="2dp"
app:dividerDirection="horizontal"
app:dividerDashGap="2dp"
app:dividerDashWidth="2dp"
app:dividerDashColor="@color/light_gray"/>
Comparator
provides a way for you to provide custom comparison logic for types that you have no control over.
Comparable
allows you to specify how objects that you are implementing get compared.
Obviously, if you don't have control over a class (or you want to provide multiple ways to compare objects that you do have control over) then use Comparator
.
Otherwise you can use Comparable
.
Please try with this
$pattern = "/My name is '\(.*\)' and im fine/";
Typically you'll need cookies to log into a site, which means cookielib, urllib and urllib2. Here's a class which I wrote back when I was playing Facebook web games:
import cookielib
import urllib
import urllib2
# set these to whatever your fb account is
fb_username = "[email protected]"
fb_password = "secretpassword"
class WebGamePlayer(object):
def __init__(self, login, password):
""" Start up... """
self.login = login
self.password = password
self.cj = cookielib.CookieJar()
self.opener = urllib2.build_opener(
urllib2.HTTPRedirectHandler(),
urllib2.HTTPHandler(debuglevel=0),
urllib2.HTTPSHandler(debuglevel=0),
urllib2.HTTPCookieProcessor(self.cj)
)
self.opener.addheaders = [
('User-agent', ('Mozilla/4.0 (compatible; MSIE 6.0; '
'Windows NT 5.2; .NET CLR 1.1.4322)'))
]
# need this twice - once to set cookies, once to log in...
self.loginToFacebook()
self.loginToFacebook()
def loginToFacebook(self):
"""
Handle login. This should populate our cookie jar.
"""
login_data = urllib.urlencode({
'email' : self.login,
'pass' : self.password,
})
response = self.opener.open("https://login.facebook.com/login.php", login_data)
return ''.join(response.readlines())
You won't necessarily need the HTTPS or Redirect handlers, but they don't hurt, and it makes the opener much more robust. You also might not need cookies, but it's hard to tell just from the form that you've posted. I suspect that you might, purely from the 'Remember me' input that's been commented out.
I needed to convert a single column of strings of form nn.n% to float. I needed to remove the % from the element in each row. The attend data frame has two columns.
attend.iloc[:,1:2]=attend.iloc[:,1:2].applymap(lambda x: float(x[:-1]))
Its an extenstion to the original answer. In my case it takes a dataframe and applies a function to each value in a specific column. The function removes the last character and converts the remaining string to float.
It's easy. Here is the full code.
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("Your URL")
driver.set_window_size(480, 320)
Make sure chrome driver is in your system path.
Try the cex
argument:
?par
cex
You can do it with templates (or SFINAE (Substitution Failure Is Not An Error)). Example:
#include <iostream>
class base
{
public:
virtual ~base() = default;
};
template <
class type,
class = decltype(
static_cast<base*>(static_cast<type*>(0))
)
>
bool check(type)
{
return true;
}
bool check(...)
{
return false;
}
class child : public base
{
public:
virtual ~child() = default;
};
class grandchild : public child {};
int main()
{
std::cout << std::boolalpha;
std::cout << "base: " << check(base()) << '\n';
std::cout << "child: " << check(child()) << '\n';
std::cout << "grandchild: " << check(grandchild()) << '\n';
std::cout << "int: " << check(int()) << '\n';
std::cout << std::flush;
}
Output:
base: true
child: true
grandchild: true
int: false
The docs give a fair indicator of what's required., however requests
allow us to skip a few steps:
You only need to install the security
package extras (thanks @admdrew for pointing it out)
$ pip install requests[security]
or, install them directly:
$ pip install pyopenssl ndg-httpsclient pyasn1
Requests will then automatically inject pyopenssl
into urllib3
If you're on ubuntu, you may run into trouble installing pyopenssl
, you'll need these dependencies:
$ apt-get install libffi-dev libssl-dev
In case you're looking for a more modern way to check to see if a service is running (this will not work for just any old process), then systemctl might be what you're looking for.
Here's the basic command:
systemctl show --property=ActiveState your_service_here
Which will yield very simple output (one of the following two lines will appear depending on whether the service is running or not running):
ActiveState=active
ActiveState=inactive
And if you'd like to know all of the properties you can get:
systemctl show --all your_service_here
If you prefer that alphabetized:
systemctl show --all your_service_here | sort
And the full code to act on it:
service=$1
result=`systemctl show --property=ActiveState $service`
if [[ "$result" == 'ActiveState=active' ]]; then
echo "$service is running" # Do something here
else
echo "$service is not running" # Do something else here
fi
Another solution for the original question, esp. useful if you want to remove only SOME of the older files in a folder, would be smth like this:
find . -name "*.sess" -mtime +100
and so on.. Quotes block shell wildcards, thus allowing you to "find" millions of files :)
$mysql -u root --host=127.0.0.1 -p
mysql>use mysql
mysql>GRANT ALL ON *.* to root@'%' IDENTIFIED BY 'redhat@123';
mysql>FLUSH PRIVILEGES;
mysql> SELECT host FROM mysql.user WHERE User = 'root';
Here is a jQuery solution that I'm using.
$("#slideshow button").click(function(){
var val = $(this).val();
console.log(val);
});
<div id="slideshow">
<img src="image1.jpg">
<button class="left" value="back">❮</button>
<button class="right" value="next">❯</button>
</div>
See this question: JADE + EXPRESS: Iterating over object in inline JS code (client-side)?
I'm having the same problem. Jade does not pass local variables in (or do any templating at all) to javascript scripts, it simply passes the entire block in as literal text. If you use the local variables 'address' and 'port' in your Jade file above the script tag they should show up.
Possible solutions are listed in the question I linked to above, but you can either: - pass every line in as unescaped text (!= at the beginning of every line), and simply put "-" before every line of javascript that uses a local variable, or: - Pass variables in through a dom element and access through JQuery (ugly)
Is there no better way? It seems the creators of Jade do not want multiline javascript support, as shown by this thread in GitHub: https://github.com/visionmedia/jade/pull/405
Do this instead:
values = [[1,2,3],[4,5]]
for x in values:
if len(x) == 3:
print(x)
Ok, first of all, use the str() function in python to turn 'number' into a string
number = 9876543210 #declaring and assigning
number = str(number) #converting
Then get the index, 0 = 1, 4 = 3 in index notation, use int() to turn it back into a number
print(int(number[3])) #printing the int format of the string "number"'s index of 3 or '6'
if you like it in the short form
print(int(str(9876543210)[3])) #condensed code lol, also no more variable 'number'
If you only want to remove it from one screen in react-native-navigation
then:
<Stack.Navigator>
<Stack.Screen
name="Login"
component={Login}
options= {{headerShown: false}} />
</Stack.Navigator>
I think you may need to stringify the data using JSON.stringify.
var data = JSON.stringify({
'StrContactDetails': Details,
'IsPrimary':true
});
$.ajax({
type: "POST",
url: @url.Action("Dhp","SaveEmergencyContact"),
data: data,
success: function(){},
contentType: 'application/json'
});
So the controller method would look like,
public ActionResult SaveEmergencyContact(string StrContactDetails, bool IsPrimary)
I usually just remove all quotes from my variables with:
set var=%var:"=%
And then apply them again wherever I need them e.g.:
echo "%var%"
You probably have a forward declaration of the class, but haven't included the header:
#include <sstream>
//...
QString Stats_Manager::convertInt(int num)
{
std::stringstream ss; // <-- also note namespace qualification
ss << num;
return ss.str();
}
In Java, there are no multi-dimension arrays. There are arrays of arrays. So:
int[][] array = new int[2][3];
It actually consists of two arrays, each has three elements.
If you really want to have named parameters plus have your objects be instances of your class, you can do the following:
class bar {
constructor (options?: {length: number; height: number;}) {
if (options) {
this.length = options.length;
this.height = options.height;
}
}
length: number;
height: number;
}
class foo {
bars: bar[] = new Array();
}
var ham = new foo();
ham.bars = [
new bar({length: 4, height: 2}),
new bar({length: 1, height: 3})
];
Also here's the related item on typescript issue tracker.
You can use this command-line parser (which you could put into a bash alias if you like), using modules built into the Perl core:
perl -MData::Dumper -MJSON::PP=from_json -ne'print Dumper(from_json($_))'
button:hover is just when you move the cursor over the button.
Try button:active instead...will work for other elements as well
button:active{_x000D_
color: red;_x000D_
}
_x000D_
Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".
/// <summary>
/// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not
/// let the JsonProperty control everything.
/// </summary>
/// <typeparam name="T"></typeparam>
public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
{
private Dictionary<string, string> PropertyMappings { get; set; }
public IgnoreJsonPropertyResolver()
{
this.PropertyMappings = new Dictionary<string, string>();
var properties = ReflectionHelper<T>.GetGetProperties(false)();
foreach (var propertyInfo in properties)
{
var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
if (jsonProperty != null)
{
PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
}
}
}
protected override string ResolvePropertyName(string propertyName)
{
string resolvedName = null;
var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
}
}
Usage:
var settings = new JsonSerializerSettings();
settings.DateFormatString = "YYYY-MM-DD";
settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
var model = new PlanViewModel() {Amount = 100};
var strModel = JsonConvert.SerializeObject(model,settings);
Model:
public class PlanViewModel
{
/// <summary>
/// The customer is charged an amount over an interval for the subscription.
/// </summary>
[JsonProperty(PropertyName = "RecurringPrice")]
public double Amount { get; set; }
/// <summary>
/// Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
/// months or years depending on the value for interval_unit.
/// </summary>
public int Interval { get; set; } = 1;
/// <summary>
/// Number of free trial days that can be granted when a customer is subscribed to this plan.
/// </summary>
public int TrialPeriod { get; set; } = 30;
/// <summary>
/// This indicates a one-time fee charged upfront while creating a subscription for this plan.
/// </summary>
[JsonProperty(PropertyName = "SetupFee")]
public double SetupAmount { get; set; } = 0;
/// <summary>
/// String representing the type id, usually a lookup value, for the record.
/// </summary>
[JsonProperty(PropertyName = "TypeId")]
public string Type { get; set; }
/// <summary>
/// Billing Frequency
/// </summary>
[JsonProperty(PropertyName = "BillingFrequency")]
public string Period { get; set; }
/// <summary>
/// String representing the type id, usually a lookup value, for the record.
/// </summary>
[JsonProperty(PropertyName = "PlanUseType")]
public string Purpose { get; set; }
}
Below is a fully functional example of what I believe you're trying to do (with a functional snippet).
Based on your question, you seem to be modifying 1 property in state
for all of your elements. That's why when you click on one, all of them are being changed.
In particular, notice that the state tracks an index of which element is active. When MyClickable
is clicked, it tells the Container
its index, Container
updates the state
, and subsequently the isActive
property of the appropriate MyClickable
s.
class Container extends React.Component {_x000D_

activeIndex: null_x000D_

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable
elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.
// New render method for `Container`
render() {
const clickables = [
{ name: "a" },
{ name: "b" },
{ name: "c" },
]
return <div>
{ clickables.map(function(clickable, i) {
return <MyClickable key={ clickable.name }
name={ clickable.name }
index={ i }
isActive={ this.state.activeIndex === i }
onClick={ this.handleClick }
/>
} )
}
</div>
}
To add a very important note on what Mark S. has mentioned in his post. In the specific SQL Script that has been mentioned in the question you can NEVER mention two different file groups for storing your data rows and the index data structure.
The reason why is due to the fact that the index being created in this case is a clustered Index on your primary key column. The clustered index data and the data rows of your table can NEVER be on different file groups.
So in case you have two file groups on your database e.g. PRIMARY and SECONDARY then below mentioned script will store your row data and clustered index data both on PRIMARY file group itself even though I've mentioned a different file group ([SECONDARY]
) for the table data. More interestingly the script runs successfully as well (when I was expecting it to give an error as I had given two different file groups :P). SQL Server does the trick behind the scene silently and smartly.
CREATE TABLE [dbo].[be_Categories](
[CategoryID] [uniqueidentifier] ROWGUIDCOL NOT NULL CONSTRAINT [DF_be_Categories_CategoryID] DEFAULT (newid()),
[CategoryName] [nvarchar](50) NULL,
[Description] [nvarchar](200) NULL,
[ParentID] [uniqueidentifier] NULL,
CONSTRAINT [PK_be_Categories] PRIMARY KEY CLUSTERED
(
[CategoryID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [SECONDARY]
GO
NOTE: Your index can reside on a different file group ONLY if the index being created is non-clustered in nature.
The below script which creates a non-clustered index will get created on [SECONDARY]
file group instead when the table data already resides on [PRIMARY]
file group:
CREATE NONCLUSTERED INDEX [IX_Categories] ON [dbo].[be_Categories]
(
[CategoryName] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [Secondary]
GO
You can get more information on how storing non-clustered indexes on a different file group can help your queries perform better. Here is one such link.
You probably want to use "eq" instead of "==". If you worry about some edge cases you may also want to check for undefined:
if (not defined $str) {
# this variable is undefined
}
If you have given same text name for both of your Id and Name properties you can give like document.getElementByName('frmMain')[index]
other wise object required error will come.And if you have only one table in your page you can use document.getElementBytag('table')[index]
.
EDIT:
You can replace the index according to your form, if its first form place 0 for index.
If you look at the output you receive from print()
and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b
):
b'{\n "note":"This file .....
If you fetch the URL using a tool such as curl -v
, you will see that the content type is
Content-Type: application/json; charset=utf-8
So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.
Change the last line of code to this:
info = json.loads(js.decode("utf-8"))
I tried:
import os
os.path.abspath(os.path.join(os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe()))), os.pardir))
If you use form.close() in your form and set the FormClosing Event of your form and either use form.close() in this Event ,you fall in unlimited loop and Argument out of range happened and the solution is that change the form.close() with form.dispose() in Event of FormClosing. I hope this little tip help you!!!
There's a strong chance that the privileges to select from table1 have been granted to a role, and the role has been granted to you. Privileges granted to a role are not available to PL/SQL written by a user, even if the user has been granted the role.
You see this a lot for users that have been granted the dba role on objects owned by sys. A user with dba role will be able to, say, SELECT * from V$SESSION
, but will not be able to write a function that includes SELECT * FROM V$SESSION
.
The fix is to grant explicit permissions on the object in question to the user directly, for example, in the case above, the SYS user has to GRANT SELECT ON V_$SESSION TO MyUser;
Here is a working example and you have to consider that every constructor with more fields should mark the extra fields as optional
.
class LocalError {
message?: string;
status?: string;
details?: Map<string, string>;
constructor(message: string);
constructor(message?: string, status?: string);
constructor(message?: string, status?: string, details?: Map<string, string>) {
this.message = message;
this.status = status;
this.details = details;
}
}
If your list has fields/properties and you want to use a specific value (e.g. FirstName), then you can do this:
string combindedString = string.Join( ",", myList.Select(t=>t.FirstName).ToArray() );
You need change instantiateItem's mFragments element getItemPosition.
if (mFragments.size() > position) {
Fragment f = mFragments.get(position);
if (f != null) {
int newPosition = getItemPosition(f);
if (newPosition == POSITION_UNCHANGED) {
return f;
} else if (newPosition == POSITION_NONE) {
mFragments.set(position, null);
} else {
mFragments.set(newPosition, f);
}
}
}
Based AndroidX FragmentStatePagerAdapter.java, because mFragments
's elements position do not change when calling notifyDataSetChanged().
You can run this project to confirm how to work. https://github.com/cuichanghao/infivt
The r
makes the string a raw string, which doesn't process escape characters (however, since there are none in the string, it is actually not needed here).
Also, re.match
matches from the beginning of the string. In other words, it looks for an exact match between the string and the pattern. To match stuff that could be anywhere in the string, use re.search
. See a demonstration below:
>>> import re
>>> line = 'This,is,a,sample,string'
>>> re.match("sample", line)
>>> re.search("sample", line)
<_sre.SRE_Match object at 0x021D32C0>
>>>
The essence is this:
This works for me:
var new_item = $('<p>hello</p>').hide();
parent.append(new_item);
new_item.show('normal');
or:
$('<p>hello</p>').hide().appendTo(parent).show('normal');
Another way:
Checkout the branch you want to revert, then reset your local working copy back to the commit that you want to be the latest one on the remote server (everything after it will go bye-bye). To do this, in SourceTree, I right-clicked on the and selected "Reset BRANCHNAME to this commit".
Then navigate to your repository's local directory and run this command:
git -c diff.mnemonicprefix=false -c core.quotepath=false push -v -f -- tags REPOSITORY_NAME BRANCHNAME:BRANCHNAME
This will erase all commits after the current one in your local repository but only for that one branch.
There are essentially three kinds of 'function calls':
Python is a PASS-BY-OBJECT-REFERENCE programming language.
Firstly, it is important to understand that a variable, and the value of the variable (the object) are two seperate things. The variable 'points to' the object. The variable is not the object. Again:
THE VARIABLE IS NOT THE OBJECT
Example: in the following line of code:
>>> x = []
[]
is the empty list, x
is a variable that points to the empty list, but x
itself is not the empty list.
Consider the variable (x
, in the above case) as a box, and 'the value' of the variable ([]
) as the object inside the box.
PASS BY OBJECT REFERENCE (Case in python):
Here, "Object references are passed by value."
def append_one(li):
li.append(1)
x = [0]
append_one(x)
print x
Here, the statement x = [0]
makes a variable x
(box) that points towards the object [0]
.
On the function being called, a new box li
is created. The contents of li
are the SAME as the contents of the box x
. Both the boxes contain the same object. That is, both the variables point to the same object in memory. Hence, any change to the object pointed at by li
will also be reflected by the object pointed at by x
.
In conclusion, the output of the above program will be:
[0, 1]
Note:
If the variable li
is reassigned in the function, then li
will point to a separate object in memory. x
however, will continue pointing to the same object in memory it was pointing to earlier.
Example:
def append_one(li):
li = [0, 1]
x = [0]
append_one(x)
print x
The output of the program will be:
[0]
PASS BY REFERENCE:
The box from the calling function is passed on to the called function. Implicitly, the contents of the box (the value of the variable) is passed on to the called function. Hence, any change to the contents of the box in the called function will be reflected in the calling function.
PASS BY VALUE:
A new box is created in the called function, and copies of contents of the box from the calling function is stored into the new boxes.
Hope this helps.
Another possible issue might be that the meta values contain non US-ASCII characters. For me it helped to UrlEncode the values when adding them to the putRequest:
request.Metadata.Add(AmzMetaPrefix + "artist", HttpUtility.UrlEncode(song.Artist));
request.Metadata.Add(AmzMetaPrefix + "title", HttpUtility.UrlEncode(song.Title));
While some of those code-snippets are short and working, they aren't trivial to follow and understand.
As i am not a fan of "copy-paste" from stack-overflow, i would like developers to understand the code they are push into they software, hope you'll find the below useful.
DEMO: Resizing images with JS and HTML Canvas Demo fiddler.
You may find 3 different methods to do this resize, that will help you understand how the code is working and why.
https://jsfiddle.net/1b68eLdr/93089/
Full code of both demo, and TypeScript method that you may want to use in your code, can be found in the GitHub project.
https://github.com/eyalc4/ts-image-resizer
This is the final code:
export class ImageTools {
base64ResizedImage: string = null;
constructor() {
}
ResizeImage(base64image: string, width: number = 1080, height: number = 1080) {
let img = new Image();
img.src = base64image;
img.onload = () => {
// Check if the image require resize at all
if(img.height <= height && img.width <= width) {
this.base64ResizedImage = base64image;
// TODO: Call method to do something with the resize image
}
else {
// Make sure the width and height preserve the original aspect ratio and adjust if needed
if(img.height > img.width) {
width = Math.floor(height * (img.width / img.height));
}
else {
height = Math.floor(width * (img.height / img.width));
}
let resizingCanvas: HTMLCanvasElement = document.createElement('canvas');
let resizingCanvasContext = resizingCanvas.getContext("2d");
// Start with original image size
resizingCanvas.width = img.width;
resizingCanvas.height = img.height;
// Draw the original image on the (temp) resizing canvas
resizingCanvasContext.drawImage(img, 0, 0, resizingCanvas.width, resizingCanvas.height);
let curImageDimensions = {
width: Math.floor(img.width),
height: Math.floor(img.height)
};
let halfImageDimensions = {
width: null,
height: null
};
// Quickly reduce the dize by 50% each time in few iterations until the size is less then
// 2x time the target size - the motivation for it, is to reduce the aliasing that would have been
// created with direct reduction of very big image to small image
while (curImageDimensions.width * 0.5 > width) {
// Reduce the resizing canvas by half and refresh the image
halfImageDimensions.width = Math.floor(curImageDimensions.width * 0.5);
halfImageDimensions.height = Math.floor(curImageDimensions.height * 0.5);
resizingCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
0, 0, halfImageDimensions.width, halfImageDimensions.height);
curImageDimensions.width = halfImageDimensions.width;
curImageDimensions.height = halfImageDimensions.height;
}
// Now do final resize for the resizingCanvas to meet the dimension requirments
// directly to the output canvas, that will output the final image
let outputCanvas: HTMLCanvasElement = document.createElement('canvas');
let outputCanvasContext = outputCanvas.getContext("2d");
outputCanvas.width = width;
outputCanvas.height = height;
outputCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
0, 0, width, height);
// output the canvas pixels as an image. params: format, quality
this.base64ResizedImage = outputCanvas.toDataURL('image/jpeg', 0.85);
// TODO: Call method to do something with the resize image
}
};

The original form is nearly perfect, you just have to omit prereq after CASE:
SELECT
CASE
WHEN prereq IS NULL THEN ' '
ELSE prereq
END AS prereq
FROM test;
Try to execute
mvn -U clean
or Run > Maven Clean and Maven > Update snapshots from project context menu in eclipse
You can change the format using the date() and the strtotime().
$date = '9/18/2019';
echo date('d-m-y',strtotime($date));
Result:
18-09-19
We can change the format by changing the ( d-m-y ).
I had the same problem. As Kristopher Johnson said, I referenced google-play-services_lib, but it didn't work. I added google_play_services_lib.jar (look at your SDK/google folder) under project properties/java build path/libraries/android dependencies and error vanished.
you can use this option for call soap with wdsl :
$opts = array(
'http' => array(
'user_agent' => 'PHPSoapClient'
)
);
$context = stream_context_create($opts);
$soapClientOptions = array(
'stream_context' => $context,
'cache_wsdl' => WSDL_CACHE_NONE
);
$wsdlUrl = 'your wsdl url';
$soapClient = new SoapClient($wsdlUrl, $soapClientOptions);
$result = $soapClient->VerifyTransaction($refNum, $MerchantCode);
The bug is probably somewhere else in your code, because it should work fine:
>>> 3 not in [2, 3, 4]
False
>>> 3 not in [4, 5, 6]
True
Or with tuples:
>>> (2, 3) not in [(2, 3), (5, 6), (9, 1)]
False
>>> (2, 3) not in [(2, 7), (7, 3), "hi"]
True
As @kgr mentioned, MySQL 8.0.11 made some changes to the authentication method.
I've opened a phpMyAdmin bug report about this: https://github.com/phpmyadmin/phpmyadmin/issues/14220.
MySQL 8.0.4-rc was working fine for me, and I kind of think it's ridiculous for MySQL to make such a change in a patch level release.
I tried this to easily use another port:
PORT=80 npm run dev
You can do it using FullscreenVideoView
class. Its a small library project. It's video progress dialog is build in. it's gradle is :
compile 'com.github.rtoshiro.fullscreenvideoview:fullscreenvideoview:1.1.0'
your VideoView xml is like this
<com.github.rtoshiro.view.video.FullscreenVideoLayout
android:id="@+id/videoview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
In your activity , initialize it using this way:
FullscreenVideoLayout videoLayout;
videoLayout = (FullscreenVideoLayout) findViewById(R.id.videoview);
videoLayout.setActivity(this);
Uri videoUri = Uri.parse("YOUR_VIDEO_URL");
try {
videoLayout.setVideoURI(videoUri);
} catch (IOException e) {
e.printStackTrace();
}
That's it. Happy coding :)
If want to know more then visit here
Edit: gradle path has been updated. compile it now
compile 'com.github.rtoshiro.fullscreenvideoview:fullscreenvideoview:1.1.2'
First make your template into a jQuery object:
var template = $("<li><div class='bar'>bla</div></li>");
Then set the attributes and append it to the DOM.
template.find('li').attr('id','1234');
$(document.body).append(template);
Note that it however makes no sense at all to add a li directly to the DOM since li should always be children of ul or ol. Also it is better to not make jQuery parse raw HTML. Instead create a li, set its attributes. Create a div and set it's attributes. Insert the div into the li and then append the li to the DOM.
here is the answer for IE 8
AND IT WORKS for alpha to work in IE8 you have to use position atribute for that element like
position:relative or other.
From Unix.SE: A simple command-line utility called gpustat
now exists: https://github.com/wookayin/gpustat.
It is free software (MIT license) and is packaged in pypi. It is a wrapper of nvidia-smi
.
Just replace it:
<li><a href="" data-toggle="modal" data-target="#modalRegister">Register</a></li>
Instead of:
<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>
Simple way to dump a Python data (e.g. dictionary) to a pickle file.
import pickle
your_dictionary = {}
pickle.dump(your_dictionary, open('pickle_file_name.p', 'wb'))
You can add it:
var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);
...but I wouldn't be surprised if by the time that ran, the browser had already made its decisions about how to render the page.
The real answer here has to be to output the correct tag from the server in the first place. (Sadly, you can't just not have the tag if you need to support IE. :-| )
Don't know much VB.NET syntax but here's and idea
Dim source As New Bitmap("C:\image.png")
Dim target As New Bitmap(size.Width, size.Height, PixelFormat.Format24bppRgb)
Using graphics As Graphics = Graphics.FromImage(target)
graphics.DrawImage(source, new Size(48, 48))
End Using
Unfortunately if you're looking to apply UIPopoverController
in iOS9, you'll get a deprecated class warning. Instead you need to set your desired view's UIModalPresentationPopover
property to achieve the same result.
Popover
In a horizontally regular environment, a presentation style where the content is displayed in a popover view. The background content is dimmed and taps outside the popover cause the popover to be dismissed. If you do not want taps to dismiss the popover, you can assign one or more views to the passthroughViews property of the associated UIPopoverPresentationController object, which you can get from the popoverPresentationController property.
In a horizontally compact environment, this option behaves the same as UIModalPresentationFullScreen.
Available in iOS 8.0 and later.
Reference: https://developer.apple.com/documentation/uikit/uiviewcontroller/1621355-modalpresentationstyle
Mark Byers' answer is excellent, but I would just add the following:
The OutputDataReceived
and ErrorDataReceived
delegates need to be removed before the outputWaitHandle
and errorWaitHandle
get disposed. If the process continues to output data after the timeout has been exceeded and then terminates, the outputWaitHandle
and errorWaitHandle
variables will be accessed after being disposed.
(FYI I had to add this caveat as an answer as I couldn't comment on his post.)
I know this is old, but I needed an answer and non of these but alpesh's answer worked for me and wanted to share with people that might had the same problem.
<script>
function confirmDelete(url) {
if (confirm("Are you sure you want to delete this?")) {
window.open(url);
} else {
false;
}
}
</script>
Normal version:
<input type="button" name="delete" value="Delete" onClick="confirmDelete('delete.php?id=123&title=Hello')">
My PHP version:
$deleteUrl = "delete.php?id=" .$id. "&title=" .$title;
echo "<input type=\"button\" name=\"delete\" value=\"Delete\" onClick=\"confirmDelete('" .$deleteUrl. "')\"/>";
This might not be the correct way of doing it publicly but this worked for me on a private site. :)
you should change like this:
private string getValue(float price)
{
if(price >0)
return "debit";
return "credit";
}
//Get value like this
select new {p.PriceID, Type = getValue(p.Price)};
Which of these three approaches is most suited for the task?
Depends on the task :-) To match exactly all Latin characters and their accented versions, the Unicode ranges probably provide the best solution. They might be extended to all non-whitespace characters, which could be done using the \S
character class.
I'm forcing a field in a UI to match the format:
last_name, first_name
(last [comma space] first)
The most basic problem I'm seeing here are not diacritics, but whitespaces. There are a few names that consist of multiple words, e.g. for titles. So you should go with the most generic, that is allowing everything but the comma that distinguishes first from last name:
/[^,]+,\s[^,]+/
But your second solution with the .
character class is just as fine, you only might need to care about multiple commata then.
$('#next').click(function(){
if($('p:last').hasClass('active'){
$('.active').removeClass();
}else{
$('.active').addClass();
}
});
Go to view all content of the site (http://yourdmain.sharepoint/sitename/_layouts/viewlsts.aspx). Select the document library "Pages" (the "Pages" library are named based on the language you created the site in. I.E. in norwegian the library is named "Sider"). Download the default.aspx to you computer and fix it (remove the web part and the <%Register tag). Save it and upload it back to the library (remember to check in the file).
EDIT:
ahh.. you are not using a publishing site template. Go to site action -> site settings. Under "site administration" select the menu "content and structure" you should now see your default.aspx page. But you cant do much with it...(delete, copy or move)
workaround: Enable publishing feature to the root web. Add the fixed default.aspx file to the Pages library and change the welcome page to this. Disable the publishing feature (this will delete all other list create from this feature but not the Pages library since one page is in use.). You will now have a new default.aspx page for the root web but the url is changed from sitename/default.aspx to sitename/Pages/default.aspx.
workaround II Use a feature to change the default.aspx file. The solution is explained here: http://wssguy.com/blogs/dan/archive/2008/10/29/how-to-change-the-default-page-of-a-sharepoint-site-using-a-feature.aspx
If using babel-preset-stage-2
then just have to start the script with --require babel-polyfill
.
In my case this error was thrown by Mocha
tests.
Following fixed the issue
mocha \"server/tests/**/*.test.js\" --compilers js:babel-register --require babel-polyfill
You can sort the dataFrame by count and then remove duplicates. I think it's easier:
df.sort_values('count', ascending=False).drop_duplicates(['Sp','Mt'])
I have published a WPF Auto Complete Text Box in WPF at CodePlex.com. You can download and try it from https://wpfautocomplete.codeplex.com/.
I happened to encounter a similar kind of issue after setting up local internal JFrog Docker Private Registry on Amazon Linux.
THE followings I did to solve the issue:
Added "--insecure-registry xx.xx.xx.xx:8081" by modifying the OPTIONS variable in the /etc/sysconfig/docker file:
OPTIONS="--default-ulimit nofile=1024:40961 --insecure-registry hostname:8081"
Then restarted the docker.
I was then able to login to the local docker registry using:
docker login -u admin -p password hostname:8081

I know it's to late, but I have a lightweight (398 bytes) script that returns if a key is being pressed: https://github.com/brunoinds/isKeyPressed
if (KeyPressing.isKeyPressed(13)){ //Pass the keyCode integer as parameter
console.log('The Enter key is being pressed!')
}else{
console.log('The Enter key is NOT being pressed!')

You can even set a interval to check if the key is being pressed:
setInterval(() => {
if (KeyPressing.isKeyPressed(13)){
console.log('The Enter key is being pressed!')
}else{
console.log('The Enter key is NOT being pressed!')
}
}, 1000) //Update data every 1000ms (1 second)
I found a solution that doesn't need to access directly the pixel data and loop through it to perform the downsampling. Depending on the size of the image this can be very resource intensive, and it would be better to use the browser's internal algorithms.
The drawImage() function is using a linear-interpolation, nearest-neighbor resampling method. That works well when you are not resizing down more than half the original size.
If you loop to only resize max one half at a time, the results would be quite good, and much faster than accessing pixel data.
This function downsample to half at a time until reaching the desired size:
function resize_image( src, dst, type, quality ) {
var tmp = new Image(),
canvas, context, cW, cH;
type = type || 'image/jpeg';
quality = quality || 0.92;
cW = src.naturalWidth;
cH = src.naturalHeight;
tmp.src = src.src;
tmp.onload = function() {
canvas = document.createElement( 'canvas' );
cW /= 2;
cH /= 2;
if ( cW < src.width ) cW = src.width;
if ( cH < src.height ) cH = src.height;
canvas.width = cW;
canvas.height = cH;
context = canvas.getContext( '2d' );
context.drawImage( tmp, 0, 0, cW, cH );
dst.src = canvas.toDataURL( type, quality );
if ( cW <= src.width || cH <= src.height )
return;
tmp.src = dst.src;
}
}
// The images sent as parameters can be in the DOM or be image objects
resize_image( $( '#original' )[0], $( '#smaller' )[0] );
Please follow the below steps.

It's broken in the exact same way decimal (base-10) notation is broken, just for base-2.
To understand, think about representing 1/3 as a decimal value. It's impossible to do exactly! In the same way, 1/10 (decimal 0.1) cannot be represented exactly in base 2 (binary) as a "decimal" value; a repeating pattern after the decimal point goes on forever. The value is not exact, and therefore you can't do exact math with it using normal floating point methods.
Historical Note: This was written at the time of PHP4. This is what we call "legacy code" now.
I have left this answer for historical purposes - but some of the methods are now deprecated, DES encryption method is not a recommended practice, etc.
I have not updated this code for two reasons: 1) I no longer work with encryption methods by hand in PHP, and 2) this code still serves the purpose it was intended for: to demonstrate the minimum, simplistic concept of how encryption can work in PHP.
If you find a similarly simplistic, "PHP encryption for dummies" kind of source that can get people started in 10-20 lines of code or less, let me know in comments.
Beyond that, please enjoy this Classic Episode of early-era PHP4 minimalistic encryption answer.
Ideally you have - or can get - access to the mcrypt PHP library, as its certainly popular and very useful a variety of tasks. Here's a run down of the different kinds of encryption and some example code: Encryption Techniques in PHP
//Listing 3: Encrypting Data Using the mcrypt_ecb Function
<?php
echo("<h3> Symmetric Encryption </h3>");
$key_value = "KEYVALUE";
$plain_text = "PLAINTEXT";
$encrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $plain_text, MCRYPT_ENCRYPT);
echo ("<p><b> Text after encryption : </b>");
echo ( $encrypted_text );
$decrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $encrypted_text, MCRYPT_DECRYPT);
echo ("<p><b> Text after decryption : </b>");
echo ( $decrypted_text );
?>
A few warnings:
1) Never use reversible, or "symmetric" encryption when a one-way hash will do.
2) If the data is truly sensitive, like credit card or social security numbers, stop; you need more than any simple chunk of code will provide, but rather you need a crypto library designed for this purpose and a significant amount of time to research the methods necessary. Further, the software crypto is probably <10% of security of sensitive data. It's like rewiring a nuclear power station - accept that the task is dangerous and difficult and beyond your knowledge if that's the case. The financial penalties can be immense, so better to use a service and ship responsibility to them.
3) Any sort of easily implementable encryption, as listed here, can reasonably protect mildly important information that you want to keep from prying eyes or limit exposure in the case of accidental/intentional leak. But seeing as how the key is stored in plain text on the web server, if they can get the data they can get the decryption key.
Be that as it may, have fun :)
When we code empty in essence could mean any one of the following given the circumstances;
In real life situation as OP stated we may wish to test them all or at times we may only wish to test for limited set of conditions.
Generally if(!a){return true;}
serves its purpose most of the time however it will not cover wider set of conditions.
Another hack that has made its round is return (!value || value == undefined || value == "" || value.length == 0);
But what if we need control on whole process?
There is no simple whiplash solution in native core JavaScript it has to be adopted. Considering we drop support for legacy IE11 (to be honest even windows has so should we) below solution born out of frustration works in all modern browsers;
function empty (a,b=[])
{if(!Array.isArray(b)) return;
var conditions=[null,'0','0.0',false,undefined,''].filter(x => !b.includes(x));
if(conditions.includes(a)|| (typeof a === 'string' && conditions.includes(a.toString().trim())))
{return true;};
return false;};`
Logic behind the solution is function has two parameters a and b, a is value we need to check, b is a array with set conditions we need to exclude from predefined conditions as listed above. Default value of b is set to an empty array [].
First run of function is to check if b is an array or not, if not then early exit the function.
next step is to compute array difference from [null,'0','0.0',false,undefined,'']
and from array b. if b is an empty array predefined conditions will stand else it will remove matching values.
conditions = [predefined set] - [to be excluded set] filter function does exactly that make use of it. Now that we have conditions in array set all we need to do is check if value is in conditions array. includes function does exactly that no need to write nasty loops of your own let JS engine do the heavy lifting.
Gotcha if we are to convert a into string for comparison then 0 and 0.0 would run fine however Null and Undefined would through error blocking whole script. We need edge case solution. Below simple || covers the edge case if first condition is not satisfied. Running another early check through include makes early exit if not met.
if(conditions.includes(a)|| (['string', 'number'].includes(typeof a) && conditions.includes(a.toString().trim())))
trim() function will cover for wider white spaces and tabs only value and will only come into play in edge case scenario.
Play ground
function empty (a,b=[]){
if(!Array.isArray(b)) return;
conditions=[null,'0','0.0',false,undefined,''].filter(x => !b.includes(x));
if(conditions.includes(a)||
(['string', 'number'].includes(typeof a) && conditions.includes(a.toString().trim()))){
return true;
}
return false;
}
console.log('1 '+empty());
console.log('2 '+empty(''));
console.log('3 '+empty(' '));
console.log('4 '+empty(0));
console.log('5 '+empty('0'));
console.log('6 '+empty(0.0));
console.log('7 '+empty('0.0'));
console.log('8 '+empty(false));
console.log('9 '+empty(null));
console.log('10 '+empty(null,[null]));
console.log('11 dont check 0 as number '+empty(0,['0']));
console.log('12 dont check 0 as string '+empty('0',['0']));
console.log('13 as number for false as value'+empty(false,[false]));
_x000D_
Lets make it complex - what if our value to compare is array its self and can be as deeply nested it can be. what if we are to check if any value in array is empty, it can be an edge business case.
function empty (a,b=[]){
if(!Array.isArray(b)) return;
conditions=[null,'0','0.0',false,undefined,''].filter(x => !b.includes(x));
if(Array.isArray(a) && a.length > 0){
for (i = 0; i < a.length; i++) { if (empty(a[i],b))return true;}
}
if(conditions.includes(a)||
(['string', 'number'].includes(typeof a) && conditions.includes(a.toString().trim()))){
return true;
}
return false;
}
console.log('checking for all values '+empty([1,[0]]));
console.log('excluding for 0 from condition '+empty([1,[0]], ['0']));

Since many of these answers are old here is how to install mysqli for Easyapache 4.
If you try and search for mysqli under your PHP extensions in WHM you are not going to find it. The way to know which extension you need to install mysqli you will need to run this command in terminal
repoquery -q --whatprovides 'ea-php70-php-mysqli' | sort -V | tail -1
Should return something like
ea-php70-php-mysqlnd-0:7.0.33-1.1.4.cpanel.x86_64
All you really need from this is mysqlnd copy it
To install mysqli using EachApache4:
You're trying to assign three separate string literals to a single string variable. A valid string variable would be 'John, Sarah, George'
. If you want embedded single quotes between the double quotes, you have to escape them.
Also, your actual SELECT
won't work, because SQL databases won't parse the string variable out into individual literal values. You need to use dynamic SQL instead, and then execute that dynamic SQL statement. (Search this site for dynamic SQL
, with the database engine you're using as the topic (as in [sqlserver] dynamic SQL
), and you should get several examples.)
Here is an example to move the mysqld tmpdir from /tmp to /run/mysqld which already exists on Ubuntu 13.04 and is a tmpfs (memory/ram):

tmpdir = /run/mysqld
Then:
sudo service mysql restart
Verify:

There is in fact a way to do this using Visual block mode. Simply pressing $A
in Visual block mode appends to the end of all lines in the selection. The appended text will appear on all lines as soon as you press Esc.
So this is a possible solution:
vip<C-V>$A,<Esc>
That is, in Normal mode, Visual select a paragraph vip
, switch to Visual block mode CTRLV, append to all lines $A
a comma ,
, then press Esc to confirm.
The documentation is at :h v_b_A
. There is even an illustration of how it works in the examples section: :h v_b_A_example
.
Since some resources are exhausted after one read, I thought why not combine the checks and the reads, instead of the traditional separate check, then read.
First we have one for the simpler check-for-null inline extension:
public static System.Collections.Generic.IEnumerable<T> ThrowOnNull<T>(this System.Collections.Generic.IEnumerable<T> source, string paramName = null) => source ?? throw new System.ArgumentNullException(paramName ?? nameof(source));
var first = source.ThrowOnNull().First();
Then we have the little more involved (well, at least the way I wrote it) check-for-null-and-empty inline extension:
public static System.Collections.Generic.IEnumerable<T> ThrowOnNullOrEmpty<T>(this System.Collections.Generic.IEnumerable<T> source, string paramName = null)
{
using (var e = source.ThrowOnNull(paramName).GetEnumerator())
{
if (!e.MoveNext())
{
throw new System.ArgumentException(@"The sequence is empty.", paramName ?? nameof(source));
}
do
{
yield return e.Current;
}
while (e.MoveNext());
}
}
var first = source.ThrowOnNullOrEmpty().First();
You can of course still call both without continuing the call chain. Also, I included the paramName, so that the caller may include an alternate name for the error if it's not "source" being checked, e.g. "nameof(target)".
To answer your extra question
:
You can set which rows should be repeated on every page using:
$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5);
Now, row 1, 2, 3, 4 and 5 will be repeated.
code:
// Create Directory if not exist then Copy a file.
public static void copyFile_Directory(String origin, String destDir, String destination) throws IOException {
Path FROM = Paths.get(origin);
Path TO = Paths.get(destination);
File directory = new File(String.valueOf(destDir));
if (!directory.exists()) {
directory.mkdir();
}
//overwrite the destination file if it exists, and copy
// the file attributes, including the rwx permissions
CopyOption[] options = new CopyOption[]{
StandardCopyOption.REPLACE_EXISTING,
StandardCopyOption.COPY_ATTRIBUTES
};
Files.copy(FROM, TO, options);
}
My few cents. The forward-slash in the package name (laravel*/*laravel) is matter. If you put back-slash you will get package not found stability error.
I assume I have import datetime
before running each of the lines of code below
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
prints "01/25/13"
.
If you can't live with the leading zero, try this:
dt = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print '{0}/{1}/{2:02}'.format(dt.month, dt.day, dt.year % 100)
This prints "1/25/13"
.
EDIT: This may not work on every platform:
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')

The hjpotter92 answer works well enough in certain cases, but I found the iframe content often got bottom-clipped in Firefox & IE, while fine in Chrome.
The following works well for me and fixes the clipping problem. The code was found at http://www.dyn-web.com/tutorials/iframes/height/. I have made a slight modification to take the onload attribute out of the HTML. Place the following code after the <iframe>
HTML and before the closing </body>
tag:
<script type="text/javascript">
function getDocHeight(doc) {
doc = doc || document;
// stackoverflow.com/questions/1145850/
var body = doc.body, html = doc.documentElement;
var height = Math.max( body.scrollHeight, body.offsetHeight,
html.clientHeight, html.scrollHeight, html.offsetHeight );
return height;
}
function setIframeHeight(id) {
var ifrm = document.getElementById(id);
var doc = ifrm.contentDocument? ifrm.contentDocument:
ifrm.contentWindow.document;
ifrm.style.visibility = 'hidden';
ifrm.style.height = "10px"; // reset to minimal height ...
// IE opt. for bing/msn needs a bit added or scrollbar appears
ifrm.style.height = getDocHeight( doc ) + 4 + "px";
ifrm.style.visibility = 'visible';
}
document.getElementById('ifrm').onload = function() { // Adjust the Id accordingly
setIframeHeight(this.id);
}
</script>
Your iframe HTML:
<iframe id="ifrm" src="some-iframe-content.html"></iframe>
Note if you prefer to include the Javascript in the <head>
of the document then you can revert to using an inline onload
attribute in the iframe
HTML, as in the dyn-web web page.
in my case it was IISExpress pointing to the same port as IIS to solve it go to
C:\Users\Your-User-Name\Documents\IISExpress\config\applicationhost.config
and search for the port, you will find <site>...</site>
tag that you need to remove or comment it
When starting the JVM, two parameters can be adjusted to suit your memory needs :
-Xms<size>
specifies the initial Java heap size and
-Xmx<size>
the maximum Java heap size.
I use the CONCATENATE
method to take the values of a column and wrap quotes around them with columns in between in order to quickly populate the WHERE IN ()
clause of a SQL statement.
I always just type =CONCATENATE("'",B2,"'",",")
and then select that and drag it down, which creates =CONCATENATE("'",B3,"'",",")
, =CONCATENATE("'",B4,"'",",")
, etc. then highlight that whole column, copy paste to a plain text editor and paste back if needed, thus stripping the row separation. It works, but again, just as a one time deal, this is not a good solution for someone who needs this all the time.

Note that dnx
has a different cache for feeding HTTP results:

CACHE http://192.168.148.21/api/odata/
Which you can clear with
dnu clear-http-cache
Now we just need to find out what the command will be on the new dotnet

In your example parts of your passed-in URL are not URL encoded (for example the colon should be %3A, the forward slashes should be %2F). It looks like you have encoded the parameters to your parameter URL, but not the parameter URL itself. Try encoding it as well. You can use encodeURIComponent
.
class MyParent:
def sayHi():
print('Mamma says hi')
from path.to.MyParent import MyParent
class ChildClass(MyParent):
pass
An instance of ChildClass
will then inherit the sayHi()
method.
Try to set web project's server propery as Local IIS if it is IIS Express. Be sure if project url is right and create virual directory.

add display:block;
and it'll work. Images are inline by default
To clarify, the default width for a block
element is auto
, which of course fills the entire available width of the containing element.
By setting the margin to auto
, the browser assigns half the remaining space to margin-left
and the other half to margin-right
.
Although a bit late, I've come across this question while searching the solution for the same problem, so I hope it can be of any help...
Found myself in the same darkness than you. Just found this article, which explains some new hints introduced in NetBeans 7.4, including this one:
https://blogs.oracle.com/netbeansphp/entry/improve_your_code_with_new
The reason why it has been added is because superglobals usually are filled with user input, which shouldn't ever be blindly trusted. Instead, some kind of filtering should be done, and that's what the hint suggests. Filter the superglobal value in case it has some poisoned content.
For instance, where I had:
$_SERVER['SERVER_NAME']
I've put instead:
filter_input(INPUT_SERVER, 'SERVER_NAME', FILTER_SANITIZE_STRING)
You have the filter_input and filters doc here:
for me setting the Dimensions to use % is what worked for me

My solution - solved it for Angular 5 with Material View
The connection is through the
formArrayName="notification"
(change)="updateChkbxArray(n.id, $event.checked, 'notification')"
This way it can work for multiple checkboxes arrays in one form. Just set the name of the controls array to connect each time.
constructor(_x000D_
private fb: FormBuilder,_x000D_
private http: Http,_x000D_
private codeTableService: CodeTablesService) {_x000D_
_x000D_
this.codeTableService.getnotifications().subscribe(response => {_x000D_
this.notifications = response;_x000D_
})_x000D_
..._x000D_
}_x000D_
_x000D_
_x000D_
createForm() {_x000D_
this.form = this.fb.group({_x000D_
notification: this.fb.array([])..._x000D_
});_x000D_
}_x000D_
_x000D_
ngOnInit() {_x000D_
this.createForm();_x000D_
}_x000D_
_x000D_
updateChkbxArray(id, isChecked, key) {_x000D_
const chkArray = < FormArray > this.form.get(key);_x000D_
if (isChecked) {_x000D_
chkArray.push(new FormControl(id));_x000D_
} else {_x000D_
let idx = chkArray.controls.findIndex(x => x.value == id);_x000D_
chkArray.removeAt(idx);_x000D_
}_x000D_
}
_x000D_
<div class="col-md-12">_x000D_
<section class="checkbox-section text-center" *ngIf="notifications && notifications.length > 0">_x000D_
<label class="example-margin">Notifications to send:</label>_x000D_
<p *ngFor="let n of notifications; let i = index" formArrayName="notification">_x000D_
<mat-checkbox class="checkbox-margin" (change)="updateChkbxArray(n.id, $event.checked, 'notification')" value="n.id">{{n.description}}</mat-checkbox>_x000D_
</p>_x000D_
</section>_x000D_
</div>
_x000D_
At the end you are getting to save the form with array of original records id's to save/update.
Will be happy to have any remarks for improvement.
There are many problems associated with this, as other have seemed to partially address:
Whether the properties others have mentioned are internal or not, you can still obtain information from them via reflection if permission allows.
var x = obj.GetType().GetProperty("Name", BindingFlags.NonPublic | BindingFlags.Instance);
You could pinvoke Win32 code for Snapshot or you can use WMI which is slower.
HANDLE CreateToolhelp32Snapshot(
DWORD dwFlags,
DWORD th32ProcessID
);
Another option would be to OpenProcess / CloseProcess, but you will still run into the same issues with exceptions being thrown same as before.
For WMI - OnNewEvent.Properties["?"]:
I realize this is a very old thread, but it was very helpful when I had to put together some system documentation for several different servers that were hosting different versions of Sql Server. I ended up creating 4 stored procedures which I am posting here for the benefit of the community. We use Dynamics NAV so the two stored procedures with NAV in the name split the Nav company out of the table name. Enjoy...

It's generally considered best-practice to only catch the errors you are interested in. In the case of shutil.rmtree
it's probably OSError
:
>>> shutil.rmtree("/fake/dir")
Traceback (most recent call last):
[...]
OSError: [Errno 2] No such file or directory: '/fake/dir'
If you want to silently ignore that error, you would do:
try:
shutil.rmtree(path)
except OSError:
pass
Why? Say you (somehow) accidently pass the function an integer instead of a string, like:
shutil.rmtree(2)
It will give the error "TypeError: coercing to Unicode: need string or buffer, int found" - you probably don't want to ignore that, which can be difficult to debug.
If you definitely want to ignore all errors, catch Exception
rather than a bare except:
statement. Again, why?
Not specifying an exception catches every exception, including the SystemExit
exception which for example sys.exit()
uses:
>>> try:
... sys.exit(1)
... except:
... pass
...
>>>
Compare this to the following, which correctly exits:
>>> try:
... sys.exit(1)
... except Exception:
... pass
...
shell:~$
If you want to write ever better behaving code, the OSError
exception can represent various errors, but in the example above we only want to ignore Errno 2
, so we could be even more specific:
import errno
try:
shutil.rmtree(path)
except OSError as e:
if e.errno != errno.ENOENT:
# ignore "No such file or directory", but re-raise other errors
raise
The following solution works for ASP.NET 5 (vNext) and it uses QueryHelpers class to build a URI with parameters.
public Uri GetUri()
{
var location = _config.Get("http://iberia.com");
Dictionary<string, string> values = GetDictionaryParameters();
var uri = Microsoft.AspNetCore.WebUtilities.QueryHelpers.AddQueryString(location, values);
return new Uri(uri);
}
private Dictionary<string,string> GetDictionaryParameters()
{
Dictionary<string, string> values = new Dictionary<string, string>
{
{ "param1", "value1" },
{ "param2", "value2"},
{ "param3", "value3"}
};
return values;
}
The result URI would have http://iberia.com?param1=value1¶m2=value2¶m3=value3
The way you describe is the way I've always done it. Since it's totally generic, you can always break that functionality out into a mixin class and inherit it in classes where you want that functionality.
class CommonEqualityMixin(object):
def __eq__(self, other):
return (isinstance(other, self.__class__)
and self.__dict__ == other.__dict__)
def __ne__(self, other):
return not self.__eq__(other)
class Foo(CommonEqualityMixin):
def __init__(self, item):
self.item = item
Dividing two integers will result in an integer (whole number) result.
You need to cast one number as a float, or add a decimal to one of the numbers, like a/350.0.
Another option is to use DecimalFormat to format your numeric String. Here is one other way to do the job without having to use String.format if you are stuck in the pre 1.5 world:
static String intToString(int num, int digits) {
assert digits > 0 : "Invalid number of digits";
// create variable length array of zeros
char[] zeros = new char[digits];
Arrays.fill(zeros, '0');
// format number as String
DecimalFormat df = new DecimalFormat(String.valueOf(zeros));
return df.format(num);
}
How about creating an ArrayList of a set amount of Integers?
The below method returns an ArrayList of a set amount of Integers.
public static ArrayList<Integer> createRandomList(int sizeParameter)
{
// An ArrayList that method returns
ArrayList<Integer> setIntegerList = new ArrayList<Integer>(sizeParameter);
// Random Object helper
Random randomHelper = new Random();
for (int x = 0; x < sizeParameter; x++)
{
setIntegerList.add(randomHelper.nextInt());
} // End of the for loop
return setIntegerList;
}
Usually I use jaxb or XMLBeans if I need to create objects serializable to XML. Now, I can see that XStream might be very useful as it's nonintrusive and has really simple api. I'll play with it soon and probably use it. The only drawback I noticed is that I can't create object's id on my own for cross referencing.
@Barak Schiller
Thanks for posting link to XStream!
Try this first, you may be passing a Null Model:
@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
<label for="Image">Change picture</label>
}
else
{
<label for="Image">Add picture</label>
}
Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.
<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>
Paolo's general idea (i.e. effectively changing some part of the request uri) is your best bet. However, I'd suggest using a more static value such as a version number that you update when you have changed your script file so that you can still get the performance gains of caching.
So either something like this:
<script src="/my/js/file.js?version=2.1.3" ></script>
or maybe
<script src="/my/js/file.2.1.3.js" ></script>
I prefer the first option because it means you can maintain the one file instead of having to constantly rename it (which for example maintains consistent version history in your source control). Of course either one (as I've described them) would involve updating your include statements each time, so you may want to come up with a dynamic way of doing it, such as replacing a fixed value with a dynamic one every time you deploy (using Ant or whatever).
I had the same problem and it was really annoying each time with the terminal. I run the command to the terminal and it was fixed

process.stderr
Instead use:
console.error
For anyone who is wonder why process.stdout.write('\033[0G');
wasn't doing anything it's because stdout
is buffered and you need to wait for drain
event (more info).
If write returns false
it will fire a drain
event.
The following configs works on Cent OS 6 or earlier
As stated above first have to disable selinux.
Step 1 nano /etc/sysconfig/selinux
Make sure the file has this configurations
SELINUX=disabled
SELINUXTYPE=targeted
Then restart the system
Step 2
iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT
Step 3
sudo service iptables save
For Cent OS 7
step 1
firewall-cmd --zone=public --permanent --add-port=8080/tcp
Step 2
firewall-cmd --reload

ECMAScript 6 introduced the let and const keywords. These keywords can be used in place of the var keyword. Contrary to the var keyword, the let and const keywords support the declaration of local scope inside block statements.
var x = 10
let y = 10
const z = 10
{
x = 20
let y = 20
const z = 20
{
x = 30
// x is in the global scope because of the 'var' keyword
let y = 30
// y is in the local scope because of the 'let' keyword
const z = 30
// z is in the local scope because of the 'const' keyword
console.log(x) // 30
console.log(y) // 30
console.log(z) // 30
}
console.log(x) // 30
console.log(y) // 20
console.log(z) // 20
}
console.log(x) // 30
console.log(y) // 10
console.log(z) // 10
My answer is WRT python 2.6.2.
import commands
status, output = commands.getstatusoutput("curl -H \"Content-Type:application/json\" -k -u (few other parameters required) -X GET https://example.org -s")
print output
I apologize for not providing the required parameters 'coz it's confidential.
I had the same problem. It turned out that I didn't specify a default page and I didn't have any page that is named after the default page convention (default.html, defult.aspx etc). As a result, ASP.NET doesn't allow the user to browse the directory (not a problem in Visual Studio built-in web server that allows you to view the directory) and shows the error message. To fix it, I added one default page in Web.Config and it worked.
<system.webServer>
<defaultDocument>
<files>
<add value="myDefault.aspx"/>
</files>
</defaultDocument>
</system.webServer>
Looking at your requirement, there is alternate solution as well. It seems you know the dimensions in dp at compile time, so you can add a dimen entry in the resources. Then you can query the dimen entry and it will be automatically converted to pixels in this call:
final float inPixels= mActivity.getResources().getDimension(R.dimen.dimen_entry_in_dp);
And your dimens.xml will have:
<dimen name="dimen_entry_in_dp">72dp</dimen>
Extending this idea, you can simply store the value of 1dp or 1sp as a dimen entry and query the value and use it as a multiplier. Using this approach you will insulate the code from the math stuff and rely on the library to perform the calculations.
I think the problem is not in sub-query but in WHERE clause of outer query. When you use
WHERE account_code between 503100 and 503105
SQL server will try to convert every value in your Account_code field to integer to test it in provided condition. Obviously it will fail to do so if there will be non-integer characters in some rows.
As written by Dave Butenhof himself:
"The biggest of all the big problems with recursive mutexes is that they encourage you to completely lose track of your locking scheme and scope. This is deadly. Evil. It's the "thread eater". You hold locks for the absolutely shortest possible time. Period. Always. If you're calling something with a lock held simply because you don't know it's held, or because you don't know whether the callee needs the mutex, then you're holding it too long. You're aiming a shotgun at your application and pulling the trigger. You presumably started using threads to get concurrency; but you've just PREVENTED concurrency."
Instead of a button, put a link and navigate it to another page
<a href="logout.php">Logout</a>
Then in logout.php
page, use
session_start();
session_destroy();
header('Location: login.php');
exit;
with pages as (
SELECT object_id, SUM (reserved_page_count) as reserved_pages, SUM (used_page_count) as used_pages,
SUM (case
when (index_id < 2) then (in_row_data_page_count + lob_used_page_count + row_overflow_used_page_count)
else lob_used_page_count + row_overflow_used_page_count
end) as pages
FROM sys.dm_db_partition_stats
group by object_id
), extra as (
SELECT p.object_id, sum(reserved_page_count) as reserved_pages, sum(used_page_count) as used_pages
FROM sys.dm_db_partition_stats p, sys.internal_tables it
WHERE it.internal_type IN (202,204,211,212,213,214,215,216) AND p.object_id = it.object_id
group by p.object_id
)
SELECT object_schema_name(p.object_id) + '.' + object_name(p.object_id) as TableName, (p.reserved_pages + isnull(e.reserved_pages, 0)) * 8 as reserved_kb,
pages * 8 as data_kb,
(CASE WHEN p.used_pages + isnull(e.used_pages, 0) > pages THEN (p.used_pages + isnull(e.used_pages, 0) - pages) ELSE 0 END) * 8 as index_kb,
(CASE WHEN p.reserved_pages + isnull(e.reserved_pages, 0) > p.used_pages + isnull(e.used_pages, 0) THEN (p.reserved_pages + isnull(e.reserved_pages, 0) - p.used_pages + isnull(e.used_pages, 0)) else 0 end) * 8 as unused_kb

left outer join extra e on p.object_id = e.object_id
Takes into account internal tables, such as those used for XML storage.
Edit: If you divide the data_kb
and index_kb
values by 1024.0, you will get the numbers you see in the GUI.
For MinGW this worked for me:
Properties
C/C++ General
- Paths and Symbols
- Includes
- GNU C++
- Include directories
Add...
Variables...
MINGW_HOME
and click OK
Apply
and OK
You should now see several MinGW paths in Includes in your project explorer.
The errors may not disappear instantly, you may need to refresh/build your project.
If you are using Cygwin, there could be an equivalent variable present.

You can still use EditorFor. Just pass the style/whichever html attribute as ViewData.
@Html.EditorFor(model => model.YourProperty, new { style = "Width:50px" })
Because EditorFor uses templates to render, you could override the default template for your property and simply pass the style attribute as ViewData.
So your EditorTemplate would like the following:
@inherits System.Web.Mvc.WebViewPage<object>
@Html.TextBoxFor(m => m, new { @class = "text ui-widget-content", style=ViewData["style"] })
FILE=test
while read CMD; do
echo "$CMD"
done < "$FILE"
A redirection with < "$FILE"
has a few advantages over cat "$FILE" | while ...
. It avoids a useless use of cat, saving an unnecessary child process. It also avoids a common pitfall where the loop runs in a subshell. In bash, commands in a |
pipeline run in subshells, which means variable assignments are lost after the loop ends. Redirection with <
doesn't have that problem, so you could use $CMD
after the loop or modify other variables inside the loop. It also, again, avoids unnecessary child processes.
There are some additional improvements that could be made:
IFS=
so that read
won't trim leading and trailing whitespace from each line.-r
to read to prevent from backslashes from being interpreted as escape sequences.CMD
and FILE
. The bash convention is only environmental and internal shell variables are uppercase.printf
in place of echo
which is safer if $cmd
is a string like -n
, which echo
would interpret as a flag.file=test
while IFS= read -r cmd; do
printf '%s\n' "$cmd"
done < "$file"
I set the following beforeShow event handler (in the options parameter) to achieve this functionality.
beforeShow: function(i) { if ($(i).attr('readonly')) { return false; } }
jQuery has the following signature for the .on()
method: .on( events [, selector ] [, data ], handler )
Events could be anyone of the ones listed on this reference:
https://developer.mozilla.org/en-US/docs/Web/Events
Though, they are not all supported by every browser.
Mozilla states the following about the input event:
The DOM input event is fired synchronously when the value of an or element is changed. Additionally, it fires on contenteditable editors when its contents are changed.

(Firstly read the other answers which has explained the for
in the <label></label>
tags.
Well, both the tops answers are correct, but for my challenge, it was when you have several radio boxes, you should select for them a common name like name="r1"
but with different ids id="r1_1" ... id="r1_2"
So this way the answer is more clear and removes the conflicts between name and ids as well.
You need different ids for different options of the radio box.
<input type="radio" name="r1" id="r1_1" />_x000D_
_x000D_
<label for="r1_1">button text one</label>_x000D_
<br/>_x000D_
<input type="radio" name="r1" id="r1_2" />_x000D_
_x000D_
<label for="r1_2">button text two</label>_x000D_
<br/>_x000D_
<input type="radio" name="r1" id="r1_3" />_x000D_
_x000D_
<label for="r1_3">button text three</label>
_x000D_
If you need one liner then maybe this would help:
reduce(lambda x, y: x + y if y[0] not in x else x, map(lambda x: [x],lst))
... should work but correct me if i'm wrong
