If you want to split only by newlines, you can use str.splitlines():
Example:
>>> data = """a,b,c
... d,e,f
... g,h,i
... j,k,l"""
>>> data
'a,b,c\nd,e,f\ng,h,i\nj,k,l'
>>> data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
With str.split() your case also works:
>>> data = """a,b,c
... d,e,f
... g,h,i
... j,k,l"""
>>> data
'a,b,c\nd,e,f\ng,h,i\nj,k,l'
>>> data.split()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
However if you have spaces (or tabs) it will fail:
>>> data = """
... a, eqw, qwe
... v, ewr, err
... """
>>> data
'\na, eqw, qwe\nv, ewr, err\n'
>>> data.split()
['a,', 'eqw,', 'qwe', 'v,', 'ewr,', 'err']
With @Lob
I always end up with a LONGTEXT
in MySQL.
To get TEXT
I declare it that way (JPA 2.0):
@Column(columnDefinition = "TEXT")
private String text
Find this better, because I can directly choose which Text-Type the column will have in database.
For columnDefinition
it is also good to read this.
EDIT: Please pay attention to Adam Siemions comment and check the database engine you are using, before applying columnDefinition = "TEXT"
.
Have a look at these pages. They contain many open source CSV parsers. JSaPar is one of them.
I'd try adding a keypress
Event
handler upon keydown
. E.g:
window.onkeydown = function() {
// evaluate key and call respective handler
window.onkeypress = function() {
// evaluate key and call respective handler
}
}
window.onkeyup = function() {
window.onkeypress = void(0) ;
}
This is just meant to illustrate a pattern; I won't go into detail here (especially not into browser specific level2+ Event
registration).
Post back please whether this helps or not.
The keyword extends
can be used for interfaces and classes only.
If you just want to declare a type that has additional properties, you can use intersection type:
type UserEvent = Event & {UserId: string}
UPDATE for TypeScript 2.2, it's now possible to have an interface that extends object-like type, if the type satisfies some restrictions:
type Event = {
name: string;
dateCreated: string;
type: string;
}
interface UserEvent extends Event {
UserId: string;
}
It does not work the other way round - UserEvent
must be declared as interface, not a type
if you want to use extends
syntax.
And it's still impossible to use extend
with arbitrary types - for example, it does not work if Event
is a type parameter without any constraints.
If you are running your code against a sqlserver database then
use this command
string sqlTrunc = "TRUNCATE TABLE " + yourTableName
SqlCommand cmd = new SqlCommand(sqlTrunc, conn);
cmd.ExecuteNonQuery();
this will be the fastest method and will delete everything from your table and reset the identity counter to zero.
The TRUNCATE keyword is supported also by other RDBMS.
5 years later:
Looking back at this answer I need to add something. The answer above is good only if you are absolutely sure about the source of the value in the yourTableName variable. This means that you shouldn't get this value from your user because he can type anything and this leads to Sql Injection problems well described in this famous comic strip. Always present your user a choice between hard coded names (tables or other symbolic values) using a non editable UI.

CASE WHEN LastName IS NULL THEN FirstName
WHEN LastName IS NOT NULL THEN LastName + ', ' + FirstName

I use someting like that: (Xamarin and C# code)
LinearLayout linLayout= new LinearLayout(this);
linLayout.SetGravity(GravityFlags.Center);
TextView txtView= new TextView(this);
linLayout.AddView(txtView);
the SetGravity puts my textView in the center of the layout. So SetGravity layout property refer to layout content
You can, use:

Bash is a Command Line Interface that was created over twenty-seven years ago by Brian Fox as a free software replacement for the Bourne Shell. A shell is a specific kind of Command Line Interface. Bash is "open source" which means that anyone can read the code and suggest changes. Since its beginning, it has been supported by a large community of engineers who have worked to make it an incredible tool. Bash is the default shell for Linux and Mac. For these reasons, Bash is the most used and widely distributed shell.
Windows has a different Command Line Interface, called Command Prompt. While this has many of the same features as Bash, Bash is much more popular. Because of the strength of the open source community and the tools they provide, mastering Bash is a better investment than mastering Command Prompt.
To use Bash on a Windows computer, we need to download and install a program called Git Bash. Git Bash (Is the Bash for windows) allows us to easily access Bash as well as another tool called Git, inside the Windows environment.
plot "data.txt" using 1:2 with lines
works for me. Do you actually have blank lines in your data file? That will cause an empty plot. Can you see a plot without data? Like plot x*x. If not, then your terminal might not be set up correctly.
Short answer: Not likely.
Long answer: Your compiler has an optimizer in it that knows how to multiply as quickly as your target processor architecture is capable. Your best bet is to tell the compiler your intent clearly (i.e. i*2 rather than i << 1) and let it decide what the fastest assembly/machine code sequence is. It's even possible that the processor itself has implemented the multiply instruction as a sequence of shifts & adds in microcode.
Bottom line--don't spend a lot of time worrying about this. If you mean to shift, shift. If you mean to multiply, multiply. Do what is semantically clearest--your coworkers will thank you later. Or, more likely, curse you later if you do otherwise.

With .Net Core it is now very easy:
Build the project Locate the .exe file in your favorite file explorer.
You could use the between function to get all records between 2010-08-03 00:00:00:000 AND 2010-08-03 23:59:59:000
It is CMD + P (or CTRL + P) by default. However the keyboard bindings may differ according to your preferences.
To know your bindings go to the "Keyboard Shortcuts" settings and search for "Go to File"
With AutoEventWireup
which is turned on by default on a page you can just add methods prepended with **Page_***event* and have ASP.NET connect to the events for you.
In the case of Unload the method signature is:
protected void Page_Unload(object sender, EventArgs e)
For details see the MSDN article.
I would check your alpha channel on your gradient colors. For me, when I was testing my code out I had the alpha channel set wrong on the colors and it did not work for me. Once I got the alpha channel set it all worked!
As explained, it is not possible. If you want to use a method of the subclass, evaluate the possibility to add the method to the superclass (may be empty) and call from the subclasses getting the behaviour you want (subclass) thanks to polymorphism. So when you call d.method() the call will succeed withoug casting, but in case the object will be not a dog, there will not be a problem
Noone here said anything about the one that comes with C++0x. If you are using a compiler and the STL that supports C++0x you could just use that instead of having another lib in your project.
UPDATE 2: A fork of this plugin has been merged with the main Eclipse Platform. You should find it pre-installed in the future Eclipse releases ;)
UPDATE: I released a new version, it's a little bit darker, now pretty everything that can be currently modified has been aligned to the theme colors. Have fun!
Here is a screenshot:
if you may like, I uploaded on github a dark theme I made some months ago to avoid blinding my eyes when spending many hours on the editor.. I made it because with all the others themes some Eclipse parts remains ugly and unstyled.
You can find it here: http://guari.github.io/eclipse-ui-theme/
With my Eclipse configurations works quite ok, if you'll find some elements that remains unstyled you can submit an issue or suggest a change and I'll try to correct it if it's possible ;) (remind that currently, CSS styling support in Eclipse it's uncomplete and sometimes buggy..)
typeOf is a C# keyword that is used when you have the name of the class. It is calculated at compile time and thus cannot be used on an instance, which is created at runtime. GetType is a method of the object class that can be used on an instance.
There is an easy, out of the box implementation: the HTML 5 input type="date"
and the other date-related input types.
Okay, you can't style the controls that much and it doesn't work on every browser, but still it can be a very good option in the long term if all modern browsers support it and don't want to include heavy libraries that don't always work that good on mobile devices.

You can use margin-top: -50% to move the text all the way to the top of the div.
margin-top: -50%;
Since C++11, there's a safe alternative to new[]
and delete[]
which is zero-overhead unlike std::vector
:
std::unique_ptr<int[]> array(new int[size]);
In C++14:
auto array = std::make_unique<int[]>(size);
Both of the above rely on the same header file, #include <memory>
With Validation
In this example I used two controls,ddl
and txtbox
, have a happy coding
asp:ScriptManager ID="script1" runat="server" /asp:ScriptManager
asp:UpdatePanel ID="Panel1" runat="server"
ContentTemplate
// ASP BUTTON
asp:Button ID="btnSave" runat="server" Text="Save" class="btn btn-success" OnClientClick="return Valid()" OnClick="btnSave_Click"
/ContentTemplate
/asp:UpdatePanel
<script type="text/javascript">
function Valid() {
if ($("#ctl00_ContentPlaceHolder1_YOUR CONTROL NAME").val() == 0) {
alert("Please select YOUR TEXT");
$("#ctl00_ContentPlaceHolder1_YOUR CONTROL NAME").focus();
return false;
}
if ($("#ctl00_ContentPlaceHolder1_YOUR CONTROL NAME").val().length == 0) {
alert("Please Type YOUR TEXT");
$("ctl00_ContentPlaceHolder1_YOUR CONTROL NAME").focus();
return false;
}
return true;
}
</script>
For Bootstrap 4 I find the following very handy because:
It is the combination of col and col-auto which does the magic. So you don't have to define a col width (like col-2,...)
<div class="row">
<div class="col">Left</div>
<div class="col-auto">Right</div>
</div>
Ideal for aligning words, icons, buttons,... to the right.
An example to have this responsive on small devices:
<div class="row">
<div class="col">Left</div>
<div class="col-12 col-sm-auto">Right (Left on small)</div>
</div>

When taking Distinct we have to cast into IEnumerable too. If list is model means, need to write code like this
IEnumerable<T> ids = list.Select(x => x).Distinct();
From Go 1.5 there's the "vendor experiment" that helps you manage dependencies. As of Go 1.6 this is no longer an experiment. Theres also some other options on the Go wiki..
Edit: as mentioned in this answer gopkg.in is a good option for pinning github-depdencies pre-1.5.
Google changed their policies last month regarding auto-play inside Chrome. Please see this announcement.
They do, however, allow auto-play if you are embedding a video and it is muted. You can add the muted
property and it should allow the video to start playing.

<source src="movie.mp4" type="video/mp4">
<source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.

self._should_continue = False
self.is_running = False
self.seconds = seconds

def _handle_target(self):
self.is_running = True
self.target()
self.is_running = False
self._start_timer()
def _start_timer(self):
if self._should_continue: # Code could have been running when cancel was called.
self.thread = Timer(self.seconds, self._handle_target)
self.thread.start()
def start(self):
if not self._should_continue and not self.is_running:
self._should_continue = True
self._start_timer()
else:
print("Timer already started or running, please wait if you're restarting.")
def cancel(self):
if self.thread is not None:
self._should_continue = False # Just in case thread is running and cancel fails.

else:
print("Timer never started or failed to initialize.")

Use StringBuilder
class. It is more efficient at what you are trying to do.
Calling Exception.ToString()
gives you more information than just using the Exception.Message
property. However, even this still leaves out lots of information, including:
Data
collection property found on all exceptions.There are times when you want to capture this extra information. The code below handles the above scenarios. It also writes out the properties of the exceptions in a nice order. It's using C# 7 but should be very easy for you to convert to older versions if necessary. See also this related answer.

Most people will be using this code for logging. Consider using Serilog with my Serilog.Exceptions NuGet package which also logs all properties of an exception but does it faster and without reflection in the majority of cases. Serilog is a very advanced logging framework which is all the rage at the time of writing.
You can use the Ben.Demystifier NuGet package to get human readable stack traces for your exceptions or the serilog-enrichers-demystify NuGet package if you are using Serilog.
What I do is put a config.php file in my root directory. This file is included by all PHP files in my project. In that config.php file, I then do the following;
define( 'ROOT_DIR', dirname(__FILE__) );
Then in all files, I know what the root of my project is and can do stuff like this
require_once( ROOT_DIR.'/include/functions.php' );
Sorry, no bonus points for getting outside of the public directory ;) This also has the unfortunate side affect that you still need a relative path for finding config.php, but it makes the rest of your includes much easier.
How can I get the value from the map, which is passed as a reference to a function?
Well, you can pass it as a reference. The standard reference wrapper that is.
typedef std::map<std::string, std::string> MAP;
// create your map reference type
using map_ref_t = std::reference_wrapper<MAP>;
// use it
void function(map_ref_t map_r)
{
// get to the map from inside the
// std::reference_wrapper
// see the alternatives behind that link
MAP & the_map = map_r;
// take the value from the map
// by reference
auto & value_r = the_map["key"];
// change it, "in place"
value_r = "new!";
}
And the test.
void test_ref_to_map() {
MAP valueMap;
valueMap["key"] = "value";
// pass it by reference
function(valueMap);
// check that the value has changed
assert( "new!" == valueMap["key"] );
}
I think this is nice and simple. Enjoy ...

maybe you want to take a look java.util.Stack
class.
it has push, pop methods. and implemented List interface.
for shift/unshift, you can reference @Jon's answer.
however, something of ArrayList you may want to care about , arrayList is not synchronized. but Stack is. (sub-class of Vector). If you have thread-safe requirement, Stack may be better than ArrayList.
Element.scrollHeight
is a property, not a function, as noted here. As noted here, the scrollHeight property is only supported after IE8. If you need it to work before that, temporarily set the CSS overflow
and height
to auto
, which will cause the div to take the maximum height it needs. Then get the height, and change the properties back to what they were before.
This can be done easily and cleanly with float
.
Demo: jsfiddle.net/KcdpW
HTML:
<ul>
<li>Item 1 <span class="right">(1)</span></li>
<li>Item 2 <span class="right">(2)</span></li>
</ul>?
CSS:
ul {
width: 10em
}
.right {
float: right
}?
overflow: hidden; /* Hide scrollbars */
now go to add file .css in project and include file
For those using the Symfony framework, the phpseclib can also be used to connect via SSH. It can be installed using composer:

$ssh = new SSH2('hostname or ip');
if (!$ssh->login('username', 'password')) {
// Login failed, do something
}
$return_value = $ssh->exec('command');

modify list of host names for your system:
C:\Windows\System32\drivers\etc\hosts
Make sure that you have the following entry:
127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem
(you may need to change modify permission to modify this file)
This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.

Had the same issue today. I added the user to:
Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Log on as a batch job
But was still getting the error. I found this post, and it turns out there's also this setting that I had to remove the user from (not sure how it got in there):
Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Deny log on as a batch job
So just be aware that you may need to check both policies for the user.

webpack
is not only in your node-modules/webpack/bin/
directory, it's also linked in node_modules/.bin
.
You have the npm bin
command to get the folder where npm will install executables.
You can use the scripts
property of your package.json
to use webpack from this directory which will be exported.
"scripts": {
"scriptName": "webpack --config etc..."
}
For example:
"scripts": {
"build": "webpack --config webpack.config.js"
}
You can then run it with:
npm run build
Or even with arguments:
npm run build -- <args>
This allow you to have you webpack.config.js
in the root folder of your project without having webpack globally installed or having your webpack configuration in the node_modules
folder.
This isn't really possible without tricks. Here is a way that works by replacing the text with an image of text.
.pvw-title{
text-indent: -9999px;
background-image: url(text_image.png)
}
This type of thing is typically done with JavaScript. Here is how it can be done with jQuery:
$('.pvw-title').text('new text');
It means that you should not share an iterator object among multiple threads. Creating multiple iterators and using them concurrently in separate threads is fine.
Updated package.json:
"build": {
"appId": "com.my-website.my-app",
"productName": "MyApp",
"copyright": "Copyright © 2019 ${author}",
"mac": {
"icon": "./public/icons/mac/icon.icns", <---------- set Mac Icons
"category": "public.app-category.utilities"
},
"win": {
"icon": "./public/icons/png/256x256.png" <---------- set Win Icon
},
"files": [
"./build/**/*",
"./dist/**/*",
"./node_modules/**/*",
"./public/**/*", <---------- need for get access to icons
"*.js"
],
"directories": {
"buildResources": "public" <---------- folder where placed icons
}
},
After build application you can see icons. This solution don't show icons in developer mode.
I don't setup icons in new BrowserWindow()
.
Just a tip:
In Visual Studio to comment a text, you can highlight the text you want to comment, and then use Ctrl + K followed by Ctrl + C. To uncomment, you can use Ctrl + K followed by Ctrl + U.
QRGen is a good library that creates a layer on top of ZXing and makes QR Code generation in Java a piece of cake.
Potatoswatter's answer is all right, but I prefer to use find
or lower_bound
instead. lower_bound
is especially useful because the iterator returned can subsequently be used for a hinted insertion, should you wish to insert something with the same key.
map<K, V>::iterator iter(my_map.lower_bound(key));
if (iter == my_map.end() || key < iter->first) { // not found
// ...
my_map.insert(iter, make_pair(key, value)); // hinted insertion
} else {
// ... use iter->second here
}
If you haven't restarted your SQL database Server after you make login changes, then make sure you do that. Start
->Programs
->Microsoft SQL Server
-> Configuration tools
-> SQL Server configuration manager
-> Restart Server
.
It looks like you only added the user to the server. You need to add them to the database too. Either open the database/Security/User/Add New User or open the server/Security/Logins/Properties/User Mapping.
From Python 3.0 changelog;
The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.
From the Python 3 email documentation it can be seen that io.StringIO
should be used instead:
from io import StringIO
from email.generator import Generator
fp = StringIO()
g = Generator(fp, mangle_from_=True, maxheaderlen=60)
g.flatten(msg)
text = fp.getvalue()
Reference: https://docs.python.org/3/library/io.html
You cannot use properties that are not mapped to a database column in a Where
expression. You must build the expression based on mapped properties, like:
var date = DateTime.Now.AddYears(-from);
result = result.Where(p => date >= p.DOB);
// you don't need `AsQueryable()` here because result is an `IQueryable` anyway
As a replacement for your not mapped Age
property you can extract this expression into a static method like so:
public class clsProfileDate
{
// ...
public DateTime DOB { get; set; } // property mapped to DB table column
public static Expression<Func<clsProfileDate, bool>> IsOlderThan(int age)
{
var date = DateTime.Now.AddYears(-age);
return p => date >= p.DOB;
}
}
And then use it this way:
result = result.Where(clsProfileDate.IsOlderThan(from));
ping (ICMP protocol) and ssh are two different protocols.
It could be that ssh service is not running or not installed
firewall restriction (local to server like iptables or even sshd config lock down ) or (external firewall that protects incomming traffic to network hosting 111.111.111.111)
First check is to see if ssh port is up
nc -v -w 1 111.111.111.111 -z 22
if it succeeds then ssh should communicate if not then it will never work until restriction is lifted or ssh is started
why not simply
public Date(){
data = new int[]{0,0,0};
}
the reason you got the error is because int[] data = ...
declares a new variable and hides the field data
however it should be noted that the contents of the array are already initialized to 0 (the default value of int
)
See debug_print_backtrace
. I guess you can call flush
afterwards if you want.
If you specify image as well as build, then Compose names the built image with the webapp and optional tag specified in image:
build: ./dir
image: webapp:tag
This results in an image named webapp
and tagged tag
, built from ./dir
.

It doesn't. Somewhere in your print stylesheet, you must have this section of code:
a[href]::after {
content: " (" attr(href) ")"
}
The only other possibility is you have an extension doing it for you.
Autocommit OFF ...
MySQL
set autocommit=0;
It sets the autommit off for the current session.
You execute your statement, see what it has changed, and then rollback if it's wrong or commit if it's what you expected !
EDIT: The benefit of using transactions instead of running select query is that you can check the resulting set easierly.
http://php.net/ereg_replace says:
Note: As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension.
Thus, preg_replace is in every way better choice. Note there are some differences in pattern syntax though.
I also hit this error…
The installation msi will try to create a new task in the Windows Task scheduler to remind you to give customer feedback. This install step executes regardless of whether you do or do not click the check box to participate in customer feedback. In many corporate environments (including mine) creating new windows tasks is denied to all but domain administrators. As a result, running as a local admin is not sufficient and the entire installation fails when adding the task returns “access denied”. This shows up in the install log as a 1603.
The only workaround we could find was to manually pull all the files out of the msi, remove the “add schedule task” from the install script, and then create a new msi. After that one line change, it worked fine.
You can simply go for: df.describe() that will provide you with all the relevant details you need, but to find the min, max or average value of a particular column (say 'weights' in your case), use:
df['weights'].mean(): For average value
df['weights'].max(): For maximum value
df['weights'].min(): For minimum value
You can do it like this:
In your main view controller:
func showModal() {
let modalViewController = ModalViewController()
modalViewController.modalPresentationStyle = .overCurrentContext
presentViewController(modalViewController, animated: true, completion: nil)
}
In your modal view controller:
class ModalViewController: UIViewController {
override func viewDidLoad() {
view.backgroundColor = UIColor.clearColor()
view.opaque = false
}
}
If you are working with a storyboard:
Just add a Storyboard Segue with Kind
set to Present Modally
to your modal view controller and on this view controller set the following values:
As Crashalot pointed out in his comment: Make sure the segue only uses Default
for both Presentation
and Transition
. Using Current Context
for Presentation
makes the modal turn black instead of remaining transparent.
Faster solution:
private boolean isPackageInstalled(String packagename, PackageManager packageManager) {
try {
packageManager.getPackageGids(packagename);
return true;
} catch (NameNotFoundException e) {
return false;
}
}
getPackageGids
is less expensive from getPackageInfo
, so it work faster.

I have 2.0 and found the above to help; however, the selecting of a static did not highlight the cell for some reason. I followed these steps:
Now your column headers should repeat on each page.
This is an old question, but I feel the urge to extend the answers with a solution I didn't see here.
You can fake the Microsoft assemly (System.Net.Http) and then use ShinsContext during the test.
Depends on your implementation and test, I would suggest to implement all the desired acting where you call a method on the HttpClient and want to fake the returned value. Using ShimHttpClient.AllInstances will fake your implementation in all the instances created during your test. For example, if you want to fake the GetAsync() method, do the following:
[TestMethod]
public void FakeHttpClient()
{
using (ShimsContext.Create())
{
System.Net.Http.Fakes.ShimHttpClient.AllInstances.GetAsyncString = (c, requestUri) =>
{
//Return a service unavailable response
var httpResponseMessage = new HttpResponseMessage(HttpStatusCode.ServiceUnavailable);
var task = Task.FromResult(httpResponseMessage);
return task;
};
//your implementation will use the fake method(s) automatically
var client = new Connection(_httpClient);
client.doSomething();
}
}
I would suggest using the String.Compare method. Using that method you can also control whether to to have it perform case-sensitive comparisons or not.
Sample:
Dim str1 As String = "String one"
Dim str2 As String = str1
Dim str3 As String = "String three"
Dim str4 As String = str3
If String.Compare(str1, str2) = 0 And String.Compare(str3, str4) = 0 Then
MessageBox.Show("str1 = str2 And str3 = str4")
Else
MessageBox.Show("Else")
End If
Edit: if you want to perform a case-insensitive search you can use the StringComparison parameter:
If String.Compare(str1, str2, StringComparison.InvariantCultureIgnoreCase) = 0 And String.Compare(str3, str4, StringComparison.InvariantCultureIgnoreCase) = 0 Then
We were having the same issues on our jenkins slaves (linux machine) and tried all the options above.
The only thing helped is setting the argument
chrome_options.add_argument('--headless')
But when we investigated further, noticed that XVFB screen doesn't started property and thats causing this error. After we fix XVFB screen, it resolved the issue.
You did not include jquery library. In jsfiddle its already there. Just include this line in your head section.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
There is a simple and very common technique by using 2 background images: a crisp and a blurry one. You set the crisp image as a background for the body and the blurry one as a background image for your container. The blurry image must be set to fixed positioning and the alignment is 100% perfect. I used it before and it works.
body {
background: url(yourCrispImage.jpg) no-repeat;
}
#container {
background: url(yourBlurryImage.jpg) no-repeat fixed;
}
You can see a working example at the following fiddle: http://jsfiddle.net/jTUjT/5/. Try to resize the browser and see that the alignment never fails.
If only CSS element()
was supported by other browsers other than Mozilla's -moz-element()
you could create great effects. See this demo with Mozilla.
You can still use the Authorization header with OAuth 2.0. There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.
It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1
E.g.:
GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer mF_9.B5f-4.1JqM
Where mF_9.B5f-4.1JqM is your OAuth access token.
for me following line is working for me , I put it in the css of my body ( where image is in same folder in which my css and .html files ) :
background: url('test.jpg');
Other thing that you must care about is , be careful about image extension , be sure that your image has .jpeg or .jpg extension. Thanks
If none of the answers worked for you. You might be in the wrong "Window". I was in "Package explorer" and switching to "Project Explorer" showed me the folders.
You can actually release your Excel Application object cleanly, but you do have to take care.
The advice to maintain a named reference for absolutely every COM object you access and then explicitly release it via Marshal.FinalReleaseComObject()
is correct in theory, but, unfortunately, very difficult to manage in practice. If one ever slips anywhere and uses "two dots", or iterates cells via a for each
loop, or any other similar kind of command, then you'll have unreferenced COM objects and risk a hang. In this case, there would be no way to find the cause in the code; you would have to review all your code by eye and hopefully find the cause, a task that could be nearly impossible for a large project.
The good news is that you do not actually have to maintain a named variable reference to every COM object you use. Instead, call GC.Collect()
and then GC.WaitForPendingFinalizers()
to release all the (usually minor) objects to which you do not hold a reference, and then explicitly release the objects to which you do hold a named variable reference.
You should also release your named references in reverse order of importance: range objects first, then worksheets, workbooks, and then finally your Excel Application object.
For example, assuming that you had a Range object variable named xlRng
, a Worksheet variable named xlSheet
, a Workbook variable named xlBook
and an Excel Application variable named xlApp
, then your cleanup code could look something like the following:
// Cleanup
GC.Collect();
GC.WaitForPendingFinalizers();
Marshal.FinalReleaseComObject(xlRng);
Marshal.FinalReleaseComObject(xlSheet);
xlBook.Close(Type.Missing, Type.Missing, Type.Missing);
Marshal.FinalReleaseComObject(xlBook);
xlApp.Quit();
Marshal.FinalReleaseComObject(xlApp);
In most code examples you'll see for cleaning up COM objects from .NET, the GC.Collect()
and GC.WaitForPendingFinalizers()
calls are made TWICE as in:
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
This should not be required, however, unless you are using Visual Studio Tools for Office (VSTO), which uses finalizers that cause an entire graph of objects to be promoted in the finalization queue. Such objects would not be released until the next garbage collection. However, if you are not using VSTO, you should be able to call GC.Collect()
and GC.WaitForPendingFinalizers()
just once.
I know that explicitly calling GC.Collect()
is a no-no (and certainly doing it twice sounds very painful), but there is no way around it, to be honest. Through normal operations you will generate hidden objects to which you hold no reference that you, therefore, cannot release through any other means other than calling GC.Collect()
.
This is a complex topic, but this really is all there is to it. Once you establish this template for your cleanup procedure you can code normally, without the need for wrappers, etc. :-)
I have a tutorial on this here:
Automating Office Programs with VB.Net / COM Interop
It's written for VB.NET, but don't be put off by that, the principles are exactly the same as when using C#.
This error occurred for me when using window.location.reload()

OCR which stands for Optical Character Recognition is a computer vision technique used to identify the different types of handwritten digits that are used in common mathematics. To perform OCR in OpenCV we will use the KNN algorithm which detects the nearest k neighbors of a particular data point and then classifies that data point based on the class type detected for n neighbors.
Data Used
This data contains 5000 handwritten digits where there are 500 digits for every type of digit. Each digit is of 20×20 pixel dimensions. We will split the data such that 250 digits are for training and 250 digits are for testing for every class.
Below is the implementation.
import numpy as np import cv2 # Read the image image = cv2.imread( 'digits.png' ) # gray scale conversion gray_img = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) # We will divide the image # into 5000 small dimensions # of size 20x20 divisions = list (np.hsplit(i, 100 ) for i in np.vsplit(gray_img, 50 )) # Convert into Numpy array # of size (50,100,20,20) NP_array = np.array(divisions) # Preparing train_data # and test_data. # Size will be (2500,20x20) train_data = NP_array[:,: 50 ].reshape( - 1 , 400 ).astype(np.float32) # Size will be (2500,20x20) test_data = NP_array[:, 50 : 100 ].reshape( - 1 , 400 ).astype(np.float32) # Create 10 different labels # for each type of digit k = np.arange( 10 ) train_labels = np.repeat(k, 250 )[:,np.newaxis] test_labels = np.repeat(k, 250 )[:,np.newaxis] # Initiate kNN classifier knn = cv2.ml.KNearest_create() # perform training of data knn.train(train_data, cv2.ml.ROW_SAMPLE, train_labels) # obtain the output from the # classifier by specifying the # number of neighbors. ret, output ,neighbours, distance = knn.findNearest(test_data, k = 3 ) # Check the performance and # accuracy of the classifier. # Compare the output with test_labels # to find out how many are wrong. matched = output = = test_labels correct_OP = np.count_nonzero(matched) #Calculate the accuracy. accuracy = (correct_OP * 100.0 ) / (output.size) # Display accuracy. print (accuracy) |

Well, I decided to workout myself on my question to solve the above problem. What I wanted is to implement a simple OCR using KNearest or SVM features in OpenCV. And below is what I did and how. (it is just for learning how to use KNearest for simple OCR purposes).
1) My first question was about letter_recognition.data
file that comes with OpenCV samples. I wanted to know what is inside that file.
It contains a letter, along with 16 features of that letter.
And this SOF
helped me to find it. These 16 features are explained in the paper Letter Recognition Using Holland-Style Adaptive Classifiers
.
(Although I didn't understand some of the features at the end)
2) Since I knew, without understanding all those features, it is difficult to do that method. I tried some other papers, but all were a little difficult for a beginner.
So I just decided to take all the pixel values as my features. (I was not worried about accuracy or performance, I just wanted it to work, at least with the least accuracy)
I took the below image for my training data:
(I know the amount of training data is less. But, since all letters are of the same font and size, I decided to try on this).
To prepare the data for training, I made a small code in OpenCV. It does the following things:
key press manually
. This time we press the digit key ourselves corresponding to the letter in the box..txt
files.At the end of the manual classification of digits, all the digits in the training data (train.png
) are labeled manually by ourselves, image will look like below:
Below is the code I used for the above purpose (of course, not so clean):
import sys
import numpy as np
import cv2
im = cv2.imread('pitrain.png')
im3 = im.copy()
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray,(5,5),0)
thresh = cv2.adaptiveThreshold(blur,255,1,1,11,2)
################# Now finding Contours ###################
contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)
samples = np.empty((0,100))
responses = []
keys = [i for i in range(48,58)]
for cnt in contours:
if cv2.contourArea(cnt)>50:
[x,y,w,h] = cv2.boundingRect(cnt)
if h>28:
cv2.rectangle(im,(x,y),(x+w,y+h),(0,0,255),2)
roi = thresh[y:y+h,x:x+w]
roismall = cv2.resize(roi,(10,10))
cv2.imshow('norm',im)
key = cv2.waitKey(0)
if key == 27: # (escape to quit)
sys.exit()
elif key in keys:
responses.append(int(chr(key)))
sample = roismall.reshape((1,100))
samples = np.append(samples,sample,0)
responses = np.array(responses,np.float32)
responses = responses.reshape((responses.size,1))
print "training complete"
np.savetxt('generalsamples.data',samples)
np.savetxt('generalresponses.data',responses)
Now we enter in to training and testing part.
For the testing part, I used the below image, which has the same type of letters I used for the training phase.
For training we do as follows:
.txt
files we already saved earlierFor testing purposes, we do as follows:
I included last two steps (training and testing) in single code below:
import cv2
import numpy as np
####### training part ###############
samples = np.loadtxt('generalsamples.data',np.float32)
responses = np.loadtxt('generalresponses.data',np.float32)
responses = responses.reshape((responses.size,1))
model = cv2.KNearest()
model.train(samples,responses)
############################# testing part #########################
im = cv2.imread('pi.png')
out = np.zeros(im.shape,np.uint8)
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
thresh = cv2.adaptiveThreshold(gray,255,1,1,11,2)
contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)
for cnt in contours:
if cv2.contourArea(cnt)>50:
[x,y,w,h] = cv2.boundingRect(cnt)
if h>28:
cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
roi = thresh[y:y+h,x:x+w]
roismall = cv2.resize(roi,(10,10))
roismall = roismall.reshape((1,100))
roismall = np.float32(roismall)
retval, results, neigh_resp, dists = model.find_nearest(roismall, k = 1)
string = str(int((results[0][0])))
cv2.putText(out,string,(x,y+h),0,1,(0,255,0))
cv2.imshow('im',im)
cv2.imshow('out',out)
cv2.waitKey(0)
And it worked, below is the result I got:
Here it worked with 100% accuracy. I assume this is because all the digits are of the same kind and the same size.
But anyway, this is a good start to go for beginners (I hope so).
There is an ActiveState recipe which implements a basic scanf http://code.activestate.com/recipes/502213-simple-scanf-implementation/

# import msvcrt
import getch
def getPass():
passwor = ''
while True:
x = getch.getch()
# x = msvcrt.getch().decode("utf-8")
if x == '\r' or x == '\n':
break
print('*', end='', flush=True)
passwor +=x
return passwor
print("\nout=", getPass())
msvcrt us only for windows, but getch from PyPI should work for both (I only tested with linux). You can also comment/uncomment the two lines to make it work for windows.
preparedStatement.setNull(index, java.sql.Types.NULL);
that should work for any type. Though in some cases failure happens on the server-side, like: for SQL:
COALESCE(?, CURRENT_TIMESTAMP)
Oracle 18XE
fails with the wrong type: expected DATE
, got STRING
-- that is a perfectly valid failure;
Bottom line: it is good to know the type if you call .setNull()

[self.view addSubview:imageview];
you can also try it this way
var data = 22;
if (Number.isInteger(data)) {
console.log("integer");
}else{
console.log("not an integer");
}
or
if (data === parseInt(data, 10)){
console.log("integer");
}else{
console.log("not an integer");
}
val aList = List( 1,2,3,4,5 )
val res3 = for ( al <- aList if al > 3 ) yield al + 1
val res4 = aList.filter(_ > 3).map(_ + 1)
println( res3 )
println( res4 )
These two pieces of code are equivalent.
val res3 = for (al <- aList) yield al + 1 > 3
val res4 = aList.map( _+ 1 > 3 )
println( res3 )
println( res4 )
These two pieces of code are also equivalent.
Map is as flexible as yield and vice-versa.
You can do this in Interface Builder.

did not have to uninstall Java JDK - just ran installer over my existing install. Not sure what was wrong but this fixed my issue with Eclipse not starting.
May I offer an alternative?
No scripting whatsoever, only standardized css styles and a little bit of creativity. Short answer - masking parts of the existing browser scrollbar, which means you retain all of it's functionality.
.scroll_content {
position: relative;
width: 400px;
height: 414px;
top: -17px;
padding: 20px 10px 20px 10px;
overflow-y: auto;
}

To create a test case template:
"New" -> "JUnit Test Case" -> Select "Class under test" -> Select "Available methods". I think the wizard is quite easy for you.
You can use a modulus to get the remainder. Though @cnicutar's answer seems cleaner/more direct.
Answer 1 worked perfectly for me. I tested it on a new MID 10' tablet. Here are the lines I added in the .inf file and it installed without a problem:
;Google MID
%SingleAdbInterface% = USB_INSTALL, USB\Vid_18d1&Pid_0003&MI_01
%CompositeAdbInterface% = USB_INSTALL, USB\Vid_18d1&Pid_0003&Rev_0230&MI_01
Grepping the URL before and after might give you some peace of mind:
svn info | grep URL
URL: svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
Relative URL: (...doesn't matter...)
And checking on your version (to be >1.7) to ensure, svn relocate
is the right thing to use:
svn --version
Lastly, adding to the above, if your repository url change also involves a change of protocol you might need to state the before and after url (also see here)
svn relocate svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
https://svngate.mycompany.org/svn/repos/trunk/DataPortal
All in one single line of course.Thereafter, get the good feeling, that all went smoothly:
svn info | grep URL:
If you feel like it, a bit more of self-assurance, the new svn repo URL is connected and working:
svn status --show-updates
svn diff

I tried the example that you have provided and the only difference is that you have True and False values switched as @bdparrish
had pointed out. Here is a working example of making an SSRS Texbox visible or hidden based on the number of rows present in a dataset. This example uses SSRS 2008 R2
.
Step-by-step process: SSRS 2008 R2
In this example, the report has a dataset named Items
and has textbox to show row counts. It also has another textbox which will be visible only if the dataset Items has rows.
Right-click on the textbox that should be visible/hidden based on an expression and select Text Box Properties...
. Refer screenshot #1.
On the Text Box Properties
dialog, click on Visibility
from the left section. Refer screenshot #2.
Select Show or hide based on an epxression
.
Click on the expression button fx
.
Enter the expression =IIf(CountRows("Items") = 0 , True, False)
. Note that this expression is to hide the Textbox (Hidden).
Click OK twice to close the dialogs.
Screenshot #3 shows data in the SQL Server table dbo.Items
, which is the source for the report data set Items
. The table contains 3 rows. Screenshot #4 shows the sample report execution against the data.
Screenshot #5 shows data in the SQL Server table dbo.Items
, which is the source for the report data set Items
. The table contains no data. Screenshot #6 shows the sample report execution against the data.
Hope that helps.

I use the following script for repairing malformed sqlite files:
#!/bin/bash
cat <( sqlite3 "$1" .dump | grep "^ROLLBACK" -v ) <( echo "COMMIT;" ) | sqlite3 "fix_$1"
Most of the time when a sqlite database is malformed it is still possible to make a dump. This dump is basically a lot of SQL statements that rebuild the database.
Some rows might be missing from the dump (probably becasue they are corrupted). If this is the case the INSERT statements of the missing rows will be replaced with some comments and the script will end with a ROLLBACK TRANSACTION.
So what we do here is we make the dump (malformed rows are excluded) and we replace the ROLLBACK with a COMMIT so that the entire dump script will be committed in stead of rolled back.
This method saved my life a couple of 100 times already \o/
You can try using like this

@@identity
function returns the last identity created in the same session.scope_identity()
function returns the last identity created in the same session and the same scope.ident_current(name)
returns the last identity created for a specific table or view in any session.identity()
function is not used to get an identity, it's used to create an identity in a select...into
query.The session is the database connection. The scope is the current query or the current stored procedure.
A situation where the scope_identity()
and the @@identity
functions differ, is if you have a trigger on the table. If you have a query that inserts a record, causing the trigger to insert another record somewhere, the scope_identity()
function will return the identity created by the query, while the @@identity
function will return the identity created by the trigger.
So, normally you would use the scope_identity()
function.
After watching the DevBytes video (by Roman Nurik) and reading the very last line in the docs, which says:
Note: If you like the auto-hiding behavior of IMMERSIVE_STICKY but need to show your own UI controls as well, just use IMMERSIVE combined with Handler.postDelayed() or something similar to re-enter immersive mode after a few seconds.
the answer, radu122 gave, worked for me. Just setup a handler and your will be good to go.
Here is the code which works for me:
@Override
protected void onResume() {
super.onResume();
executeDelayed();
}
private void executeDelayed() {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
// execute after 500ms
hideNavBar();
}
}, 500);
}
private void hideNavBar() {
if (Build.VERSION.SDK_INT >= 19) {
View v = getWindow().getDecorView();
v.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
Google says "after a few seconds" - but I want to provide this functionality as soon as possible. Maybe I will change the value later, if I have to, I will update this answer.

Question is about merging two images, however in this specified case you shouldn't do that. You should put Content Image (ie. cover) into <img />
tag, and Style Image into CSS, why?
So use a very simple code:
<div class="cover">
<img src="/content/images/covers/movin-mountains.png" alt="Moving mountains by Pneuma" width="100" height="100" />
</div>
.cover {
padding: 10px;
padding-right: 100px;

You have to leave Python 2.4 installed on RHEL/Centos; otherwise, tools start breaking. You can do a dual-install, though; I talk about this here:
The post is about 2.6, but applies equally to 2.7.
MySQLi stands for MySQL improved. It's an object-oriented interface to the MySQL bindings which makes things easier to use. It also offers support for prepared statements (which are very useful). If you're on PHP 5 use MySQLi.
The only correct answer to this question is that you need to set the parents to a proper width (in this case FILL_PARENT
, WRAP_CONTENT
) and use android:layout_weight=1
for the textview that needs to be wrapped.
SingleLine
is on by default so that won't make any changes.
A width
set to 0px will work but is not a good solution.
Some example (in a tableview this time), using xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<TableLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:stretchColumns="*"
android:id="@+id/tableLayout1">
<TableRow android:id="@+id/tableRow1" android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:text="test1" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="0" />
<TextView android:layout_weight="1"
android:text="test2 very long text that needs to be wrapped properly using layout_weight property and ignoring singleline since that is set by default..."
android:layout_width="fill_parent" android:layout_height="wrap_content" />
</TableRow>
</TableLayout>
</LinearLayout>
If you want to set this in code you're looking for the layout_weight as a third parameter as in this example where it is set to 1:
row.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView label = new TextView(getApplicationContext());
label.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT, 1f));
Nearly everyone gives how directly, let me show the evolvement:
you can use the instance methods of Array:
// general form of closure
images.sortInPlace({ (image1: imageFile, image2: imageFile) -> Bool in return image1.fileID > image2.fileID })
// types of closure's parameters and return value can be inferred by Swift, so they are omitted along with the return arrow (->)
images.sortInPlace({ image1, image2 in return image1.fileID > image2.fileID })
// Single-expression closures can implicitly return the result of their single expression by omitting the "return" keyword
images.sortInPlace({ image1, image2 in image1.fileID > image2.fileID })
// closure's argument list along with "in" keyword can be omitted, $0, $1, $2, and so on are used to refer the closure's first, second, third arguments and so on
images.sortInPlace({ $0.fileID > $1.fileID })
// the simplification of the closure is the same
images = images.sort({ (image1: imageFile, image2: imageFile) -> Bool in return image1.fileID > image2.fileID })
images = images.sort({ image1, image2 in return image1.fileID > image2.fileID })
images = images.sort({ image1, image2 in image1.fileID > image2.fileID })
images = images.sort({ $0.fileID > $1.fileID })
For elaborate explanation about the working principle of sort, see The Sorted Function.
The most efficient is to create a buffer of the correct size and then read the file into the buffer.
#include <fstream>
#include <vector>
int main()
{
std::ifstream file("Plop");
if (file)
{
/*
* Get the size of the file
*/
file.seekg(0,std::ios::end);
std::streampos length = file.tellg();
file.seekg(0,std::ios::beg);
/*
* Use a vector as the buffer.
* It is exception safe and will be tidied up correctly.
* This constructor creates a buffer of the correct length.
* Because char is a POD data type it is not initialized.
*
* Then read the whole file into the buffer.
*/
std::vector<char> buffer(length);
file.read(&buffer[0],length);
}
}
Very short answer: you are looking for your property in the scope of a particular class loader instead of you target class. This should work:
File file = new File(getClass().getResource("jsonschema.json").getFile());
JsonNode mySchema = JsonLoader.fromFile(file);
Also, see this:
P.S. there can be an issue if the project has been compiled on one machine and after that has been launched on another or you run your app in Docker. In this case, paths to your resource folder can be invalid. In this case it would be better to determine paths to your resources at runtime:
ClassPathResource res = new ClassPathResource("jsonschema.json");
File file = new File(res.getPath());
JsonNode mySchema = JsonLoader.fromFile(file);
Update from 2020
On top of that if you want to read resource file as a String in your tests, for example, you can use these static utils methods:
public static String getResourceFileAsString(String fileName) {
InputStream is = getResourceFileAsInputStream(fileName);
if (is != null) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
return (String)reader.lines().collect(Collectors.joining(System.lineSeparator()));
} else {
throw new RuntimeException("resource not found");
}
}
public static InputStream getResourceFileAsInputStream(String fileName) {
ClassLoader classLoader = {CurrentClass}.class.getClassLoader();
return classLoader.getResourceAsStream(fileName);
}
Example of usage:
String soapXML = getResourceFileAsString("some_folder_in_resources/SOPA_request.xml");
If you are given this format it takes like a link to another page or another link.partial view majorly used for renduring the html files from one place to another.
var googleResponse = $('#g-recaptcha-response').val();
if(googleResponse=='')
{
$("#texterr").html("<span>Please check reCaptcha to continue.</span>");
return false;
}
This is how I do it, basically str.replace(/[\""]/g, '\\"')
.
var display = document.getElementById('output');_x000D_
var str = 'class="whatever-foo__input" id="node-key"';_x000D_
display.innerHTML = str.replace(/[\""]/g, '\\"');_x000D_
_x000D_
//will return class=\"whatever-foo__input\" id=\"node-key\"
_x000D_
<span id="output"></span>

I always use this:
// Lock form
this.MaximumSize = this.Size;

jbeard4 solution worked beautifully.
I'm using Raphael SketchPad to create an SVG. Link to the files in step 1.
For a Save button (id of svg is "editor", id of canvas is "canvas"):
$("#editor_save").click(function() {
// the canvg call that takes the svg xml and converts it to a canvas
canvg('canvas', $("#editor").html());
// the canvas calls to output a png
var canvas = document.getElementById("canvas");
var img = canvas.toDataURL("image/png");
// do what you want with the base64, write to screen, post to server, etc...
});
I followed approach as shown in code below to return a dictionary. Created a class and declared dictionary as global and created a function to add value corresponding to some keys in dictionary.

You can use the Execute Package Utility to change your datasource, before running the package.
You can run your package using DTEXEC, and change your connection by passing in a /CONNECTION parameter. Probably save it as a batch so next time you don't need to type the whole thing and just change the datasource as required.
You can use the SSIS XML package configuration file. Here is a walk through.
You can save your configrations in a database table.

With the new definition of aside, it’s crucial to remain aware of its context. >When used within an article element, the contents should be specifically related >to that article (e.g., a glossary). When used outside of an article element, the >contents should be related to the site (e.g., a blogroll, groups of additional >navigation, and even advertising if that content is related to the page).
You're looking for is called an IDENTITY column:
create table student (
sid integer not null GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1)

A sequence is another option for doing this, but you need to determine which one is proper for your particular situation. Read this for more information comparing sequences to identity columns.
java.net.URLEncoder.encode(String s, String encoding)
can help too. It follows the HTML form encoding application/x-www-form-urlencoded
.
URLEncoder.encode(query, "UTF-8");
On the other hand, Percent-encoding (also known as URL encoding) encodes space with %20
. Colon is a reserved character, so :
will still remain a colon, after encoding.
I solved that problem by doing this:
You can use
LEFT(column, length)
or
SUBSTRING(column, start index, length)
This simple piece of code can check for deeply nested variable / value existence without having to check each variable along the way...
var getValue = function( s, context ){
return Function.call( context || null, 'return ' + s )();
}
Ex. - a deeply nested array of objects:
a = [
{
b : [
{
a : 1,
b : [
{
c : 1,
d : 2 // we want to check for this
}
]
}
]
}
]
Instead of :
if(a && a[0] && a[0].b && a[0].b[0] && a[0].b[0].b && a[0].b[0].b[0] && a[0].b[0].b[0].d && a[0].b[0].b[0].d == 2 ) // true
We can now :
if( getValue('a[0].b[0].b[0].d') == 2 ) // true
Cheers!

//pop the elements from the array
objs.pop();
return objs;
}
}
let pushObj = new PushObjects();

Make some invisible HTML tags like <label>, <p>, <input>
etc. and name its id, and the class name is a pattern so that you can retrieve it later.
Let you have two lists maintenance_next[] and maintenance_block_time[] of the same length, and you want to pass these two list's data to javascript using the flask. So you take some invisible label tag and set its tag name is a pattern of list's index and set its class name as value at index.
{% for i in range(maintenance_next|length): %}_x000D_
<label id="maintenance_next_{{i}}" name="{{maintenance_next[i]}}" style="display: none;"></label>_x000D_
<label id="maintenance_block_time_{{i}}" name="{{maintenance_block_time[i]}}" style="display: none;"></label>_x000D_
{% endfor%}
_x000D_
Now you can retrieve the data in javascript using some javascript operation like below -
<script>_x000D_
var total_len = {{ total_len }};_x000D_
_x000D_
for (var i = 0; i < total_len; i++) {_x000D_
var tm1 = document.getElementById("maintenance_next_" + i).getAttribute("name");_x000D_
var tm2 = document.getElementById("maintenance_block_time_" + i).getAttribute("name");_x000D_
_x000D_
//Do what you need to do with tm1 and tm2._x000D_
_x000D_
console.log(tm1);_x000D_
console.log(tm2);_x000D_
}_x000D_
</script>

Modules are by no means deprecated and are used heavily in the VB language. It's the only way for instance to implement an extension method in VB.Net.
There is one huge difference between Modules and Classes with Static Members. Any method defined on a Module is globally accessible as long as the Module is available in the current namespace. In effect a Module allows you to define global methods. This is something that a class with only shared members cannot do.
Here's a quick example that I use a lot when writing VB code that interops with raw COM interfaces.
Module Interop
Public Function Succeeded(ByVal hr as Integer) As Boolean
...
End Function
Public Function Failed(ByVal hr As Integer) As Boolean
...
End Function
End Module
Class SomeClass
Sub Foo()
Dim hr = CallSomeHrMethod()
if Succeeded(hr) then
..
End If
End Sub
End Class
As Gerben suggested, just change:
order deny,allow
deny from all
to
order allow,deny

You have to put your main queue dispatching in the block that runs the computation. For example (here I create a dispatch queue and don't use a global one):
dispatch_queue_t queue = dispatch_queue_create("com.example.MyQueue", NULL);
dispatch_async(queue, ^{
// Do some computation here.
// Update UI after computation.
dispatch_async(dispatch_get_main_queue(), ^{
// Update the UI on the main thread.
});
});
Of course, if you create a queue don't forget to dispatch_release

Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection
Dim source_file() As String
Dim i As Integer
queue.Add fso.GetFolder(source) 'obviously replace
Do While queue.Count > 0
Set oFolder = queue(1)
queue.Remove 1 'dequeue
'...insert any folder processing code here...
For Each oSubfolder In oFolder.SubFolders
queue.Add oSubfolder 'enqueue
Next oSubfolder
For Each oFile In oFolder.Files
'...insert any file processing code here...
'Debug.Print oFile
i = i + 1
ReDim Preserve source_file(i)
source_file(i) = oFile
Next oFile
Loop
GetDirectoryName = source_file
End Function
And here you can call function:
Sub test()
Dim s
For Each s In GetDirectoryName("C:\New folder")
Debug.Print s
Next
End Sub
You can get the current page, post, or custom post type with the global variable $post
:
echo $post->post_title
Note: In a function or class you'll need to specify global $post;
prior to trying to use $post
.
If you have loops on your page, make sure you end each loop with wp_reset_postdata();
to set $post
back to the default item being displayed (the page).
Note, the 'post_title' variable is also available for any custom loop / query... including menu items and media attachments... everything in WordPress is a 'post'.
Here's an elegant array formula (which I found here http://www.excel-easy.com/examples/count-unique-values.html) that does the trick nicely:
Type
=SUM(1/COUNTIF(List,List))
and confirm with CTRL-SHIFT-ENTER
datediff(to_date(String timestamp), to_date(String timestamp))
For example:
SELECT datediff(to_date('2019-08-03'), to_date('2019-08-01')) <= 2;
You can use JavaScript's encodeURIComponent
:
encodeURIComponent('select * from table where i()')
giving
'select%20*%20from%20table%20where%20i()'
Sliding the space bar only works if you gave more then one input language selected.
In that case the space bar will also indicate the selected language and show arrows to indicate Sliding will change selection.
This is easy fast and changes the dictionary at the same time.
First response seems the mist accurate.

When importing to Eclipse project, I accidentally did:
BAD: Import...
>> General
>> Existing Proejcts into Workspace
when I should have done instead:
GOOD: Import...
>> Android
>> Existing Android Code Into Workspace
Removing the project imported with first method, and then re-importing it with the second method solved the problem for me.
(Others have written similar answers but I didn't get it until the explicit comparison.)

CSS Flexbox is well supported these days. Go here for a good tutorial on flexbox.
This works fine in all newer browsers:
#container {_x000D_
display: flex;_x000D_
flex-wrap: wrap;_x000D_
justify-content: center;_x000D_
}_x000D_
_x000D_
.block {_x000D_
width: 150px;_x000D_
height: 150px;_x000D_
background-color: #cccccc;_x000D_
margin: 10px; _x000D_
}
_x000D_
<div id="container">_x000D_
<div class="block">1</div> _x000D_
<div class="block">2</div> _x000D_
<div class="block">3</div> _x000D_
<div class="block">4</div> _x000D_
<div class="block">5</div> _x000D_
</div>
_x000D_
Some may ask why not use display: inline-block? For simple things it is fine, but if you got complex code within the blocks, the layout may not be correctly centered anymore. Flexbox is more stable than float left.
When you execute a method (i.e. function assigned to an object), inside it you can use this
variable to refer to this object, for example:
var obj = {_x000D_
someProperty: true,_x000D_
someMethod: function() {_x000D_
console.log(this.someProperty);_x000D_
}_x000D_
};_x000D_
obj.someMethod(); // logs true
_x000D_
If you assign a method from one object to another, its this
variable refers to the new object, for example:
var obj = {_x000D_
someProperty: true,_x000D_
someMethod: function() {_x000D_
console.log(this.someProperty);_x000D_
}_x000D_
};_x000D_
_x000D_
var anotherObj = {_x000D_
someProperty: false,_x000D_
someMethod: obj.someMethod_x000D_
};_x000D_
_x000D_
anotherObj.someMethod(); // logs false
_x000D_
The same thing happens when you assign requestAnimationFrame
method of window
to another object. Native functions, such as this, has build-in protection from executing it in other context.
There is a Function.prototype.call()
function, which allows you to call a function in another context. You just have to pass it (the object which will be used as context) as a first parameter to this method. For example alert.call({})
gives TypeError: Illegal invocation
. However, alert.call(window)
works fine, because now alert
is executed in its original scope.
If you use .call()
with your object like that:
support.animationFrame.call(window, function() {});
it works fine, because requestAnimationFrame
is executed in scope of window
instead of your object.
However, using .call()
every time you want to call this method, isn't very elegant solution. Instead, you can use Function.prototype.bind()
. It has similar effect to .call()
, but instead of calling the function, it creates a new function which will always be called in specified context. For example:
window.someProperty = true;_x000D_
var obj = {_x000D_
someProperty: false,_x000D_
someMethod: function() {_x000D_
console.log(this.someProperty);_x000D_
}_x000D_
};_x000D_
_x000D_
var someMethodInWindowContext = obj.someMethod.bind(window);_x000D_
someMethodInWindowContext(); // logs true
_x000D_
The only downside of Function.prototype.bind()
is that it's a part of ECMAScript 5, which is not supported in IE <= 8. Fortunately, there is a polyfill on MDN.
As you probably already figured out, you can use .bind()
to always execute requestAnimationFrame
in context of window
. Your code could look like this:
var support = {
animationFrame: (window.requestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.msRequestAnimationFrame ||
window.oRequestAnimationFrame).bind(window)
};
Then you can simply use support.animationFrame(function() {});
.
Using suggestions from answers on this page and this other one (ANT_HOME is set incorrectly or ant could not be located), the ultimate fix was the following:
Adding a ANT_HOME environment variable that points to the ROOT directory of your Apache ant directory location. (Not the bin sub-dir!)
Adding a JAVA_HOME environment variable that points to the ROOT directory of your Java JDK (or SDK) directory location. (NOT your JRE and not the bin sub-dir!)
Appended %ANT_HOME%\bin;%JAVA_HOME%\bin to the PATH environment variable.
Make sure you close any command window(s) that were open prior to the changes above. Only command windows opened after the changes will have the updated environment variables.
You need to create both a URL
object and a URLConnection
object. The following code will test both the format of the URL and whether a connection can be established:
try {
URL url = new URL("http://www.yoursite.com/");
URLConnection conn = url.openConnection();
conn.connect();
} catch (MalformedURLException e) {
// the URL is not in a valid form
} catch (IOException e) {
// the connection couldn't be established
}
Chrome since ~Sep/Oct 2014 makes fonts subject to the same CORS checks as Firefox has done https://code.google.com/p/chromium/issues/detail?id=286681. There is a discussion on this in https://groups.google.com/a/chromium.org/forum/?fromgroups=#!topic/blink-dev/TT9D5-Zfnzw
Given that for fonts the browser may do a preflight check, then your S3 policy needs the cors request header as well. You can check your page in say Safari (which at present doesn't do CORS checking for fonts) and Firefox (that does) to double check this is the problem described.
See Stack overflow answer on Amazon S3 CORS (Cross-Origin Resource Sharing) and Firefox cross-domain font loading for the Amazon S3 CORS details.
NB in general because this used to apply to Firefox only, so it may help to search for Firefox rather than Chrome.
Java versions before version 7 allow for these three combinations of try-catch-finally...
try - catch
try - catch - finally
try - finally
finally
block will be always executed no matter of what's going on in the try
or/and catch
block. so if there is no catch
block, the exception won't be handled here.
However, you will still need an exception handler somewhere in your code - unless you want your application to crash completely of course. It depends on the architecture of your application exactly where that handler is.
- Java try block must be followed by either catch or finally block.
- For each try block there can be zero or more catch blocks, but only one finally block.
- The finally block will not be executed if program exits(either by calling System.exit() or by causing a fatal error that causes the process to abort).
If you compile with optimizations enabled, then many variables will be removed; for example:
SomeType value = GetValue();
DoSomething(value);
here the local variable value
would typically get removed, keeping the value on the stack instead - a bit like as if you had written:
DoSomething(GetValue());
Also, if a return value isn't used at all, then it will be dropped via "pop" (rather than stored in a local via "stloc", and again; the local will not exist).
Because of this, in such a build the debugger can't get the current value of value
because it doesn't exist - it only exists for the brief instant between GetValue()
and DoSomething(...)
.
So; if you want to debug... don't use a release build! or at least, disable optimizations while you debug.

The following functions (modified BFS with a recursive path-finding function between two nodes) will do the job for an acyclic graph:
from collections import defaultdict
# modified BFS
def find_all_parents(G, s):
Q = [s]
parents = defaultdict(set)
while len(Q) != 0:
v = Q[0]
Q.pop(0)
for w in G.get(v, []):
parents[w].add(v)
Q.append(w)
return parents
# recursive path-finding function (assumes that there exists a path in G from a to b)
def find_all_paths(parents, a, b):
return [a] if a == b else [y + b for x in list(parents[b]) for y in find_all_paths(parents, a, x)]
For example, with the following graph (DAG) G
given by
G = {'A':['B','C'], 'B':['D'], 'C':['D', 'F'], 'D':['E', 'F'], 'E':['F']}
if we want to find all paths between the nodes 'A'
and 'F'
(using the above-defined functions as find_all_paths(find_all_parents(G, 'A'), 'A', 'F')
), it will return the following paths:
Take a look at the Python tutorial section 4.7.3 and 4.7.4. It talks about passing tuples as arguments.
I would also consider using named parameters (and passing a dictionary) instead of using a tuple and passing a sequence. I find the use of positional arguments to be a bad practice when the positions are not intuitive or there are multiple parameters.
According to documentation you're correct (http://php.net/manual/en/pdo.connections.php):
The connection remains active for the lifetime of that PDO object. To close the connection, you need to destroy the object by ensuring that all remaining references to it are deleted--you do this by assigning NULL to the variable that holds the object. If you don't do this explicitly, PHP will automatically close the connection when your script ends.
Note that if you initialise the PDO object as a persistent connection it will not automatically close the connection.
there is a limited alternative you can use

class std_int_vector: public std::vectror<int> {}
A::A() : vector(new std_int_vector()) {}

the method modify()
that you called in the last is called in global context
if you want to override modify()
you first have to inherit A
or B
.
Maybe you're trying to do this:
In this case C
inherits A
function A() {
this.modify = function() {
alert("in A");
}
}
function B() {
this.modify = function() {
alert("in B");
}
}
C = function() {
this.modify = function() {
alert("in C");
};
C.prototype.modify(); // you can call this method where you need to call modify of the parent class
}
C.prototype = new A();
This below code just show the very basic use of delegate concept .. you name the variable and class as per your requirement.
First you need to declare a protocol:
Let's call it MyFirstControllerDelegate.h
@protocol MyFirstControllerDelegate
- (void) FunctionOne: (MyDataOne*) dataOne;
- (void) FunctionTwo: (MyDatatwo*) dataTwo;
@end
Import MyFirstControllerDelegate.h file and confirm your FirstController with protocol MyFirstControllerDelegate
#import "MyFirstControllerDelegate.h"
@interface FirstController : UIViewController<MyFirstControllerDelegate>
{
}
@end
In the implementation file, you need to implement both functions of protocol:
@implementation FirstController
- (void) FunctionOne: (MyDataOne*) dataOne
{
//Put your finction code here
}
- (void) FunctionTwo: (MyDatatwo*) dataTwo
{
//Put your finction code here
}
//Call below function from your code
-(void) CreateSecondController
{
SecondController *mySecondController = [SecondController alloc] initWithSomeData:.];
//..... push second controller into navigation stack
mySecondController.delegate = self ;
[mySecondController release];
}
@end
in your SecondController:
@interface SecondController:<UIViewController>
{
id <MyFirstControllerDelegate> delegate;
}
@property (nonatomic,assign) id <MyFirstControllerDelegate> delegate;
@end
In the implementation file of SecondController.
@implementation SecondController
@synthesize delegate;
//Call below two function on self.
-(void) SendOneDataToFirstController
{
[delegate FunctionOne:myDataOne];
}
-(void) SendSecondDataToFirstController
{
[delegate FunctionTwo:myDataSecond];
}
@end
Here is the wiki article on delegate.
My problem was in web.xml
file. In one <servlet-mapping>
there was an error inside <url-pattern>
: I forgot to add /
before url.
Marked answer work!! but Not in my case there's more then one datepicker and only want to implement on particular datepicker
So I use instance of dp and find datepicker Div and add hide class
Here's Code
<style>
.hide-day-calender .ui-datepicker-calendar{
display:none;
}
</style>
<script>
$('#dpMonthYear').datepicker({
changeMonth: true,
changeYear: true,
showButtonPanel: true,
dateFormat: 'MM yy',
onClose: function (dateText, inst) {
$(this).datepicker('setDate', new Date(inst.selectedYear, inst.selectedMonth, 1));
},
beforeShow: function (elem,dp) {
$(dp.dpDiv).addClass('hide-day-calender'); //here a change
}
});
</script>
Note: You can not target
.ui-datepicker-calendar
and set css, because it will constantly rendering while selection/changes
In the case where the problem is that System.loadLibrary cannot find the DLL in question, one common misconception (reinforced by Java's error message) is that the system property java.library.path is the answer. If you set the system property java.library.path to the directory where your DLL is located, then System.loadLibrary will indeed find your DLL. However, if your DLL in turn depends on other DLLs, as is often the case, then java.library.path cannot help, because the loading of the dependent DLLs is managed entirely by the operating system, which knows nothing of java.library.path. Thus, it is almost always better to bypass java.library.path and simply add your DLL's directory to LD_LIBRARY_PATH (Linux), DYLD_LIBRARY_PATH (MacOS), or Path (Windows) prior to starting the JVM.
(Note: I am using the term "DLL" in the generic sense of DLL or shared library.)

Just copy and paste the code above in your text editor, change the few variables accordingly and VOILA! I wrote an article about this and I've done it many times. See a demo here.
I think you need separately date parts like (day, Month, Year)
DateTime today = DateTime.Today;
Will not work for your case. You can get date separately so you don't need variable today
to be as a DateTime
Type, so lets just give today
variable int
Type because the day is only int. So today is 10 March 2020 then the result of
int today = DateTime.Today.Day;
int month = DateTime.Today.Month;
int year = DateTime.Today.Year;
MessageBox.Show(today.ToString()+ " - this is day. "+month.ToString()+ " - this is month. " + year.ToString() + " - this is year");
would be "10 - this is day. 3 - this is month. 2020 - this is year"

let vc = self.storyboard!.instantiateViewController(withIdentifier: "CVIdentifier")
self.present(vc, animated: true, completion: nil)
For urls (as it seems to be a part of the topic by the given example), one can do something like this:
import os
url = 'http://www.stackoverflow.com'
name,ext = os.path.splitext(url)
print (name, ext)
#Or:
ext = '.'+url.split('.')[-1]
name = url[:-len(ext)]
print (name, ext)
Both will output:
('http://www.stackoverflow', '.com')
This can also be combined with str.endswith(suffix)
if you need to just split ".com", or anything specific.
You can actually achieve the same effect as a background image with the img tag. You just have to set its z-index lower than everything else, set position:absolute and use a transparent background for every box in the foreground.
var collections = db.getCollectionNames();
for(var i = 0; i< collections.length; i++){
print('Collection: ' + collections[i]); // print the name of each collection
db.getCollection(collections[i]).find().forEach(printjson); //and then print the json of each of its elements
}
I think this script might get what you want. It prints the name of each collection and then prints its elements in json.
The easiest way is to convert to a date:
SELECT *
FROM dbo.LogRequests
WHERE cast(dateX as date) = '2014-05-09';
Often, such expressions preclude the use of an index. However, according to various sources on the web, the above is sargable (meaning it will use an index), such as this and this.
I would be inclined to use the following, just out of habit:
SELECT *
FROM dbo.LogRequests
WHERE dateX >= '2014-05-09' and dateX < '2014-05-10';
I was able to fix this by installing the typings
module.
npm install -g typings
typings install
(Using ng 2.0.0-rc.1)
If you still have the serial console open, it will reserve the serial port. Close it, and try again.
\r
can do the work here for you.
sed
can perform text transformations on input stream from a file or from a pipeline. Example:
echo 'C:\foo\bar.xml' | sed 's/\\/\//g'
gets
C:/foo/bar.xml
You can't refer to a property of an object before you have initialized that object; use an external variable.
var key1 = "it";
var obj = {
key1 : key1,
key2 : key1 + " works!"
};
Also, this is not a "JSON object"; it is a Javascript object. JSON is a method of representing an object with a string (which happens to be valid Javascript code).
It's very simple.
The checkbox field is like an input text. If you don't write anything in the field, it will say the field doesn't exist.
<form method="post">
<input type="checkbox" name="check">This is how it works!<br>
<button type="submit" name="submit">Submit</button>
</form>
<?php
if(isset($_POST['submit'])) {
if(!isset($_POST['check'])) {
echo "Not selected!";
}else{
echo "Selected!";
}
}
?>
