It just looks for the presence of the .git directory in the solution folder. Delete that folder, possibly hidden, and Visual Studio will no longer consider it a git project.

Building on @user3114046's answer:
x <- data.frame(q=1,w=2,e=3)
x
# q w e
#1 1 2 3
names(x)[match(oldnames,names(x))] <- newnames
x
# A w B
#1 1 2 3
This won't be reliant on a specific ordering of columns in the x

From ScottGu's blog:
Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:
The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:
Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).
Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.
This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.
Also see this.
In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".
Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.
Wikipedia
There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.
For fine-grained timing on OS X, you should use mach_absolute_time( )
declared in <mach/mach_time.h>
:
#include <mach/mach_time.h>
#include <stdint.h>
// Do some stuff to setup for timing
const uint64_t startTime = mach_absolute_time();
// Do some stuff that you want to time
const uint64_t endTime = mach_absolute_time();
// Time elapsed in Mach time units.
const uint64_t elapsedMTU = endTime - startTime;
// Get information for converting from MTU to nanoseconds
mach_timebase_info_data_t info;
if (mach_timebase_info(&info))
handleErrorConditionIfYoureBeingCareful();
// Get elapsed time in nanoseconds:
const double elapsedNS = (double)elapsedMTU * (double)info.numer / (double)info.denom;
Of course the usual caveats about fine-grained measurements apply; you're probably best off invoking the routine under test many times, and averaging/taking a minimum/some other form of processing.
Additionally, please note that you may find it more useful to profile your application running using a tool like Shark. This won't give you exact timing information, but it will tell you what percentage of the application's time is being spent where, which is often more useful (but not always).

on windows I made the iis development certificate trusted by using MMC (start > run > mmc), then add the certificate snapin, choosing "local computer" and accepting the defaults. Once that certificate snapip is added expand the local computer certificate tree to look under Personal, select the localhost certificate, right click > all task > export. accept all defaults in the exporting wizard.
Once that file is saved, expand trusted certificates and begin to import the cert you just exported. https://localhost
is now trusted in chrome having no security warnings.
I used this guide resolution #2 from the MSDN blog, the op also shared a link in his question about that also should using MMC but this worked for me. resolution #2

On Linux, you can download the Docker Compose binary from the Compose repository release page on GitHub. Follow the instructions from the link, which involve running the curl command in your terminal to download the binaries. These step-by-step instructions are also included below.
1:Run this command to download the current stable release of Docker Compose:
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
To install a different version of Compose, substitute 1.26.2 with the version of Compose you want to use.
2:Apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
Note: If the command docker-compose fails after installation, check your path. You can also create a symbolic link to /usr/bin or any other directory in your path.

Here is nice documentation on APIs,
https://developer.chrome.com/apps/notifications
And, official video explanation by Google,
The constructor of unique_ptr<T>
accepts a raw pointer to an object of type T
(so, it accepts a T*
).
In the first example:
unique_ptr<int> uptr (new int(3));
The pointer is the result of a new
expression, while in the second example:
unique_ptr<double> uptr2 (pd);
The pointer is stored in the pd
variable.
Conceptually, nothing changes (you are constructing a unique_ptr
from a raw pointer), but the second approach is potentially more dangerous, since it would allow you, for instance, to do:
unique_ptr<double> uptr2 (pd);
// ...
unique_ptr<double> uptr3 (pd);
Thus having two unique pointers that effectively encapsulate the same object (thus violating the semantics of a unique pointer).
This is why the first form for creating a unique pointer is better, when possible. Notice, that in C++14 we will be able to do:
unique_ptr<int> p = make_unique<int>(42);
Which is both clearer and safer. Now concerning this doubt of yours:
What is also not clear to me, is how pointers, declared in this way will be different from the pointers declared in a "normal" way.
Smart pointers are supposed to model object ownership, and automatically take care of destroying the pointed object when the last (smart, owning) pointer to that object falls out of scope.
This way you do not have to remember doing delete
on objects allocated dynamically - the destructor of the smart pointer will do that for you - nor to worry about whether you won't dereference a (dangling) pointer to an object that has been destroyed already:
{
unique_ptr<int> p = make_unique<int>(42);
// Going out of scope...
}
// I did not leak my integer here! The destructor of unique_ptr called delete
Now unique_ptr
is a smart pointer that models unique ownership, meaning that at any time in your program there shall be only one (owning) pointer to the pointed object - that's why unique_ptr
is non-copyable.
As long as you use smart pointers in a way that does not break the implicit contract they require you to comply with, you will have the guarantee that no memory will be leaked, and the proper ownership policy for your object will be enforced. Raw pointers do not give you this guarantee.
You can use parents() to get all parents with the given selector.
Description: Get the ancestors of each element in the current set of matched elements, optionally filtered by a selector.
But parent() will get just the first parent of the element.
Description: Get the parent of each element in the current set of matched elements, optionally filtered by a selector.
And there is .parentsUntil() which I think will be the best.
Description: Get the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector.

From the Fragment
documentation:
Often you will want one Fragment to communicate with another, for example to change the content based on a user event. All Fragment-to-Fragment communication is done through the associated Activity. Two Fragments should never communicate directly.
So I suggest you have look on the basic fragment training docs in the documentation. They're pretty comprehensive with an example and a walk-through guide.
Funny you brought this up, I just had the exact same problem. I solved it eventually, but I'm still unsure as to what caused it.
Try checking your bin/pip
and bin/activate
scripts. In bin/pip
, look at the shebang. Is it correct? If not, correct it. Then on line ~42
in your bin/activate
, check to see if your virtualenv path is right. It'll look something like this
VIRTUAL_ENV="/Users/me/path/to/virtual/environment"
If it's wrong, correct it, deactivate
, then . bin/activate
, and if our mutual problem had the same cause, it should work. If it still doesn't, you're on the right track, anyway. I went through the same problem solving routine as you did, which pip
ing over and over, following the stack trace, etc.
Make absolutely sure that
/Users/kristof/VirtualEnvs/testpy3/bin/pip3
is what you want, and not referring to another similarly-named test project (I had that problem, and have no idea how it started. My suspicion is running multiple virtualenvs at the same time).
If none of this works, a temporary solution may be to, as Joe Holloway said,
Just run the virtualenv's pip with its full path (i.e. don't rely on searching the executable path) and you don't even need to activate the environment. It will do the right thing.
Perhaps not ideal, but it ought to work in a pinch.
Link to my original question:
I have the answer to this problem from the BlackBerry SDK side of things: For some reason, no matter how many times I changed the options in the compiler, the actual underlying settings file did not change.
Have a look in the .settings folder of your project for a file called org.eclipse.jdt.core.prefs.
In there you can modify the settings manually:
org.eclipse.jdt.core.compiler.debug.lineNumber=generate
edit: Further to this, I have noticed that sometimes I can ignore the alert Eclipse gives, and it will still stop at the required place... curioser and curioser... I put this into the bucket of things we learn to deal with when working as dev.
As Karim said, cross domain ajax doesn't work unless the server allows for it. In this case Google does not, BUT, there is a simple trick to get around this in many cases. Just have your local server pass the content retrieved through HTTP or HTTPS.
For example, if you were using PHP, you could:
Create the file web_root/ajax_responders/google.php with:
<?php
echo file_get_contents('http://www.google.de');
?>
And then alter your code to connect to that instead of to Google's domain directly in the javascript:
var response = $.ajax({ type: "GET",
url: "/ajax_responders/google.php",
async: false
}).responseText;
alert(response);
You can use something like this
<div class="row">
<div class="col-xs-2">
<select id="info_type" class="form-control">
<option>College</option>
<option>Exam</option>
</select>
</div>
</div>

General interface that represents binding results. Extends the interface for error registration capabilities, allowing for a Validator to be applied, and adds binding-specific analysis and model building.

What exactly do you mean by "starts my php script"? What kind of PHP script? One to generate an HTML response for an end-user, or one that simply performs some kind of data processing task? If you are familiar with using the tag and how it interacts with PHP, then you should only need to POST to your target PHP script using an button of type "submit". If you are not familiar with forms, take a look here.

A .o object file file (also .obj on Windows) contains compiled object code (that is, machine code produced by your C or C++ compiler), together with the names of the functions and other objects the file contains. Object files are processed by the linker to produce the final executable. If your build process has not produced these files, there is probably something wrong with your makefile/project files.

It's best to use whatever one reads better - there's in all practical effect 0 difference between performance.
In this case I think the last statement reads better than the first if statement, but careful not to overuse the ternary operator - sometimes it can really make things a lot less clear.
You need to use ==
or ===
for comparison. =
assigns a new value.
Besides that, using ==
is pointless when dealing with booleans only. Just use if(foo)
instead of if(foo == true)

With a named URL you could do:
(r'^login/', login_view, name='login'),

For those who use ASP.NET Identity 2.1 and have changed the primary key from the default string
to either int
or Guid
, if you're still getting
EntityType 'xxxxUserLogin' has no key defined. Define the key for this EntityType.
EntityType 'xxxxUserRole' has no key defined. Define the key for this EntityType.
you probably just forgot to specify the new key type on IdentityDbContext
:
public class AppIdentityDbContext : IdentityDbContext<
AppUser, AppRole, int, AppUserLogin, AppUserRole, AppUserClaim>
{
public AppIdentityDbContext()

{
}
......
}
If you just have
public class AppIdentityDbContext : IdentityDbContext
{
......
}
or even
public class AppIdentityDbContext : IdentityDbContext<AppUser>
{
......
}
you will get that 'no key defined' error when you are trying to add migrations or update the database.

For completeness, I think the best way, if possible, is to use server redirects, so send a 301 status code. This is easy to do via .htaccess

In most of the cases it’s only a need for the transpiler/bundler, which might not be configured to work with JSX files, but with JS! So you are forced to use JS files instead of JSX.
And since react is just a library for javascript, it makes no difference for you to choose between JSX or JS. They’re completely interchangeable!
In some cases users/developers might also choose JSX over JS, because of code highlighting, but the most of the newer editors are also viewing the react syntax correctly in JS files.

Otherwise, you can use:

There's a subset of Google Analytics js library called ga-lite that you can cache however you want.

I'd probably split the long statement up into multiple shorter statements so that the program logic is separated from the definition of the long string:
>>> def fun():
... format_string = '{0} Here is a really long ' \
... 'sentence with {1}'
... print format_string.format(3, 5)
If the string is only just too long and you choose a short variable name then by doing this you might even avoid having to split the string:
>>> def fun():
... s = '{0} Here is a really long sentence with {1}'
... print s.format(3, 5)
String literals and constants are interned by default.
That is, "foo" == "foo"
(declared by the String literals), but new String("foo") != new String("foo")
.
Full Example (Python 3):
For Python 2.x look into Note below
import re
mylist = ["dog", "cat", "wildcat", "thundercat", "cow", "hooo"]
r = re.compile(".*cat")
newlist = list(filter(r.match, mylist)) # Read Note
print(newlist)
Prints:
['cat', 'wildcat', 'thundercat']
Note:
For Python 2.x developers, filter
returns a list already. In Python 3.x filter
was changed to return an iterator so it has to be converted to list
(in order to see it printed out nicely).
OnClientClick="SomeMethod()"
event of that BUTTON, it return by default "true
" so after that function it do postback
for solution use
//use this code in BUTTON ==> OnClientClick="return SomeMethod();"
//and your function like this
<script type="text/javascript">
function SomeMethod(){
// put your code here
return false;
}
</script>
To preserve newlines use |
, for example:
|
This is a very long sentence
that spans several lines in the YAML
but which will be rendered as a string
with newlines preserved.
is translated to "This is a very long sentence?\n that spans several lines in the YAML?\n but which will be rendered as a string?\n with newlines preserved.\n"
If you don't have a modifiable lvalue of an iterator, or it is desired to get a copy of a given iterator (leaving the original one unchanged), then C++11 comes with new helper functions - std::next
/ std::prev
:
std::next(iter, 2); // returns a copy of iter incremented by 2
std::next(std::begin(v), 2); // returns a copy of begin(v) incremented by 2
std::prev(iter, 2); // returns a copy of iter decremented by 2

What do you get when you do puts lines
? That will give you a clue.
By default File.open
opens the file in text mode, so your \r\n
characters will be automatically converted to \n
. Maybe that's the reason lines
are always equal to lines2
. To prevent Ruby from parsing the line ends use the rb
mode:
C:\> copy con lala.txt a file with many lines ^Z C:\> irb irb(main):001:0> text = File.open('lala.txt').read => "a\nfile\nwith\nmany\nlines\n" irb(main):002:0> bin = File.open('lala.txt', 'rb').read => "a\r\nfile\r\nwith\r\nmany\r\nlines\r\n" irb(main):003:0>
But from your question and code I see you simply need to open the file with the default modifier. You don't need any conversion and may use the shorter File.read
.
The code you have is a white with low opacity.
If something white with a low opacity is above something black, you end up with a lighter shade of gray. Above red? Lighter red, etc. That is how opacity works.
Here is a simple demo.
If you want it to look 'more white', make it less opaque:
background:rgba(255,255,255, 0.9);
By now there are 4 different ways to document objects as parameters/types. Each has its own uses. Only 3 of them can be used to document return values, though.
For objects with a known set of properties (Variant A)
/**
* @param {{a: number, b: string, c}} myObj description
*/
This syntax is ideal for objects that are used only as parameters for this function and don't require further description of each property.
It can be used for @returns
as well.
For objects with a known set of properties (Variant B)
Very useful is the parameters with properties syntax:
/**
* @param {Object} myObj description
* @param {number} myObj.a description
* @param {string} myObj.b description
* @param {} myObj.c description
*/
This syntax is ideal for objects that are used only as parameters for this function and that require further description of each property.
This can not be used for @returns
.
For objects that will be used at more than one point in source
In this case a @typedef comes in very handy. You can define the type at one point in your source and use it as a type for @param
or @returns
or other JSDoc tags that can make use of a type.
/**
* @typedef {Object} Person
* @property {string} name how the person is called
* @property {number} age how many years the person lived
*/
You can then use this in a @param
tag:
/**
* @param {Person} p - Description of p
*/
Or in a @returns
:
/**
* @returns {Person} Description
*/
For objects whose values are all the same type
/**
* @param {Object.<string, number>} dict
*/
The first type (string) documents the type of the keys which in JavaScript is always a string or at least will always be coerced to a string. The second type (number) is the type of the value; this can be any type.
This syntax can be used for @returns
as well.
Resources
Useful information about documenting types can be found here:
https://jsdoc.app/tags-type.html
PS:
to document an optional value you can use []
:
/**
* @param {number} [opt_number] this number is optional
*/
or:
/**
* @param {number|undefined} opt_number this number is optional
*/
You can use 'dict comprehension'
my_dict = {row[0]: row[1] for row in df.values}
You can simply go Netbeans, in the design view, go to JFrame
property, choose icon image property, Choose Set Form's iconImage
property using: "Custom code" and then in the Form.SetIconImage()
function put the following code:
Toolkit.getDefaultToolkit().getImage(name_of_your_JFrame.class.getResource("image.png"))
Do not forget to import:
import java.awt.Toolkit;
in the source code!
If you want to obfuscate, use this:
System.out.println( 1 & Boolean.hashCode( true ) >> 1 ); // 1
System.out.println( 1 & Boolean.hashCode( false ) >> 1 ); // 0
In more recent versions of SQL Server Management studio, you can now right click on a database and 'Take Database Offline'. This gives you the option to Drop All Active Connections to the database.

For me, this seems to work (Using IPv6 rather than IPv4) I don't know if this is different for some websites but for mine this works.
Google will eventually block your IP when you exceed a certain amount of requests.

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.
In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.
Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.
There is no way to do it in one line with assignment as value.
var a = b = 0;
makes b global. A correct way (without leaking variables) is the slightly longer:
var a = 0, b = a;
which is useful in the case:
var a = <someLargeExpressionHere>, b = a, c = a, d = a;
If you need to return an IHttpActionResult and want to return the error code plus a message, use:
return ResponseMessage(Request.CreateErrorResponse(HttpStatusCode.NotModified, "Error message here"));
you should try:
request.url
It suppose to work always, even on localhost (just did it).
I had another approach like: setting the launchMode
of my activity to singleTop
and without calling finish()
, just startActivity(getIntent())
will do the job. Just have to care about the new data both in onCreate()
and onNewIntent
. With Sush's way, the application may blink like AMAN SINGH said. But AMAN SINGH's approach will still create a new activity which is somehow, unnecessary, even if he fixed the 'blink' problem, I think.
Too late for this question, but if someone looking for a solution, here it is.
It won't work if your file InputStream.Position is set to the end of the stream. My additional lines:
Stream stream = file.InputStream;
stream.Position = 0;
Here is your code for add data into both tableView:
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var table1Text: UITextField!
@IBOutlet weak var table2Text: UITextField!
@IBOutlet weak var table1: UITableView!
@IBOutlet weak var table2: UITableView!
var table1Data = ["a"]
var table2Data = ["1"]
override func viewDidLoad() {
super.viewDidLoad()
}
@IBAction func addData(sender: AnyObject) {
//add your data into tables array from textField
table1Data.append(table1Text.text)
table2Data.append(table2Text.text)
dispatch_async(dispatch_get_main_queue(), { () -> Void in
//reload your tableView
self.table1.reloadData()
self.table2.reloadData()
})
table1Text.resignFirstResponder()
table2Text.resignFirstResponder()
}
//delegate methods
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == table1 {
return table1Data.count
}else if tableView == table2 {
return table2Data.count
}
return Int()
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView == table1 {
let cell = table1.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = table1Data[row]
return cell
}else if tableView == table2 {
let cell = table2.dequeueReusableCellWithIdentifier("Cell1", forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = table2Data[row]
return cell
}
return UITableViewCell()
}
}
And your result will be:
Unlike some browsers, Java follows the HTTPS specification strictly when it comes to the server identity verification (RFC 2818, Section 3.1) and IP addresses.
When using a host name, it's possible to fall back to the Common Name in the Subject DN of the server certificate, instead of using the Subject Alternative Name.
When using an IP address, there must be a Subject Alternative Name entry (of type IP address, not DNS name) in the certificate.
You'll find more details about the specification and how to generate such a certificate in this answer.
Strings, by C
definition, are terminated by '\0'
. You have no "C strings"
in your program.
Your program reads characters (buffered till ENTER) from the standard input (the keyboard) and writes them back to the standard output (the screen). It does this no matter how many characters you type or for how long you do this.
To stop the program you have to indicate that the standard input has no more data (huh?? how can a keyboard have no more data?).
You simply press Ctrl+D (Unix) or Ctrl+Z (Windows) to pretend the file has reached its end.
Ctrl+D (or Ctrl+Z) are not really characters in the C
sense of the word.
If you run your program with input redirection, the EOF
is the actual end of file, not a make belief one
./a.out < source.c
Try This :
<input type="text" onkeypress = "return isDigit(event,this.value);"/>
function isDigit(evt, txt) {
var charCode = (evt.which) ? evt.which : event.keyCode
var c = String.fromCharCode(charCode);
if (txt.indexOf(c) > 0 && charCode == 46) {
return false;
}
else if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57)) {
return false;
}
return true;
}
Call this function from input textbox on onkeypress event
The Java compiler assumes that your input is UTF-8 encoded, either because you specified it to be or because it's your platform default encoding.
However, the data in your .java
files is not actually encoded in UTF-8. The problem is probably the ¬
character. Make sure your editor (or IDE) of choice actually safes its file in UTF-8 encoding.
I just want to add to all great answers above,
that if you write a library it's a good practice to use ConfigureAwait(false)
and get better performance, as said here.
So this snippet seems to be better:
public static async Task DoWork()
{
int[] ids = new[] { 1, 2, 3, 4, 5 };
await Task.WhenAll(ids.Select(i => DoSomething(1, i))).ConfigureAwait(false);
}

I reached the point that I set, up to max_iter=1200000
on my LinearSVC
classifier, but still the "ConvergenceWarning" was still present. I fix the issue by just setting dual=False
and leaving max_iter
to its default.
With LogisticRegression(solver='lbfgs')
classifier, you should increase max_iter
. Mine have reached max_iter=7600
before the "ConvergenceWarning" disappears when training with large dataset's features.
I think you want to change the setting called "DropDownStyle" to be "DropDownList".
The "IIS APPPOOL\AppPoolName" will work, but as mentioned previously, it does not appear to be a valid AD name so when you search for it in the "Select User or Group" dialog box, it won't show up (actually, it will find it, but it will think its an actual system account, and it will try to treat it as such...which won't work, and will give you the error message about it not being found).
How I've gotten it to work is:
As long as the AppPool name actually exists, the login should now be created.
You should use the HasValue
property:
SomeProperty.HasValue
For example:
if (SomeProperty.HasValue)
{
// Do Something
}
else
{
// Do Something Else
}
FYI
public Nullable<System.Guid> SomeProperty { get; set; }
is equivalent to:
public System.Guid? SomeProperty { get; set; }

This answer is provided for future reference to all those that bump into this problem. Solution consists of two things:
ModelStateException
that gets thrown when validation fails on the server (model state reports validation errors when we use data annotations and use strong typed controller action parameters)HandleModelStateExceptionAttribute
that catches custom exception and returns HTTP error status with model state error in the bodyThis provides the optimal infrastructure for jQuery Ajax calls to use their full potential with success
and error
handlers.
$.ajax({
type: "POST",
url: "some/url",
success: function(data, status, xhr) {
// handle success
},
error: function(xhr, status, error) {
// handle error
}
});
[HandleModelStateException]
public ActionResult Create(User user)
{
if (!this.ModelState.IsValid)
{
throw new ModelStateException(this.ModelState);
}
// create new user because validation was successful
}
The whole problem is detailed in this blog post where you can find all the code to run this in your application.
I found the problem. It was the hibernate3.jar. I don't know why it was not well extracted from the .zip, maybe corrupt. A good way to check if jars are corrupt or not is navigating through their tree structure in "Project Explorer" in Eclipse: if you can't expand a jar node probably it's corrupt. I've seen that having corrupt packages it's frequent when you drag and drop them to the "Project Explorer". Maybe it's better to move and copy them in the OS environment! Thankyou all.
For a Maven project using NetBeans 8.x:
An example name/value pair might resemble:
javax.persistence.jdbc.password=PASSWORD
Then run your project:
main(...)
.The command line parameters should appear in the Run window.
Note that to obtain the value form with the program, use System.getProperty()
.
Additional actions for Test file, Run project, and other ways to run the application can have arguments defined. Repeat the steps above for the different actions to accomplish this task.
If you are doing this in more than one place in your application it would make sense to use a client-side JSON database because creating custom search functions is messy and less maintainable than the alternative.
Check out ForerunnerDB which provides you with a very powerful client-side JSON database system and includes a very simple query language to help you do exactly what you are looking for:
// Create a new instance of ForerunnerDB and then ask for a database
var fdb = new ForerunnerDB(),
db = fdb.db('myTestDatabase'),
coll;
// Create our new collection (like a MySQL table) and change the default
// primary key from "_id" to "id"
coll = db.collection('myCollection', {primaryKey: 'id'});
// Insert our records into the collection
coll.insert([
{"name":"my Name","id":12,"type":"car owner"},
{"name":"my Name2","id":13,"type":"car owner2"},
{"name":"my Name4","id":14,"type":"car owner3"},
{"name":"my Name4","id":15,"type":"car owner5"}
]);
// Search the collection for the string "my nam" as a case insensitive
// regular expression - this search will match all records because every
// name field has the text "my Nam" in it
var searchResultArray = coll.find({
name: /my nam/i
});
console.log(searchResultArray);
/* Outputs
[
{"name":"my Name","id":12,"type":"car owner"},
{"name":"my Name2","id":13,"type":"car owner2"},
{"name":"my Name4","id":14,"type":"car owner3"},
{"name":"my Name4","id":15,"type":"car owner5"}
]

Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.
[Update] As mentioned by @Aftershock in the comments, util.pump
is gone and was replaced with a method on the Stream prototype called pipe
; the code below reflects this.
var http = require('http'),
fileSystem = require('fs'),
path = require('path');
http.createServer(function(request, response) {
var filePath = path.join(__dirname, 'myfile.mp3');
var stat = fileSystem.statSync(filePath);
response.writeHead(200, {
'Content-Type': 'audio/mpeg',
'Content-Length': stat.size
});
var readStream = fileSystem.createReadStream(filePath);
// We replaced all the event handlers with a simple call to readStream.pipe()
readStream.pipe(response);
})
.listen(2000);

Try
$ git diff --stat --color master..branchName
This will give you more info about each change, while still using the same number of lines.
You can also flip the branches to get an even clearer picture of the difference if you were to merge the other way:

Please see my project of the cross-browser filter of value of the text input element on your web page using JavaScript language: Input Key Filter . You can filter the value as an integer number, a float number, or write a custom filter, such as a phone number filter. See an example of code of input an integer number:

It is well defined behaviour. You cannot get the old value for a mutated object. That's because both the newVal
and oldVal
refer to the same object. Vue will not keep an old copy of an object that you mutated.
Had you replaced the object with another one, Vue would have provided you with correct references.

A good way to add external JARs to your Android project or any Java project is:
libs
in your project's root folderlibs
folderNow right click on the Jar file and then select Build Path > Add to Build Path, which will create a folder called 'Referenced Libraries' within your project
By doing this, you will not lose your libraries that are being referenced on your hard drive whenever you transfer your project to another computer.
For Android Studio
Please Note : If you are using 3rd party libraries then it is better to use transitive dependencies where Gradle script automatically downloads the JAR and the dependency JAR when gradle script run.
Ex : compile 'com.google.android.gms:play-services-ads:9.4.0'

I agree with the points dnmckee mentions, plus:
I created a custom view that is at 100%. Use the dropdowns then click to view page layout to go back to a smaller view.
Try this:

var_dump($arr);
// will print
// array(0) { }

Where specific formatting is required, you should write your own routine or use a library function that does what you need. The basic ECMAScript functionality is usually insufficient for displaying formatted numbers.
A thorough explanation of rounding and formatting is here: http://www.merlyn.demon.co.uk/js-round.htm#RiJ
As a general rule, rounding and formatting should only be peformed as a last step before output. Doing so earlier may introduce unexpectedly large errors and destroy the formatting.

You can use df.index
to access the index object and then get the values in a list using df.index.tolist()
. Similarly, you can use df['col'].tolist()

Although Objective-C does indeed appear to be "insane" initially, I encourage you to stick with it. Once you have an "a-ha" moment, suddenly it all starts to make sense. For me it took about 2 weeks of focused Objective-C concentration to really understand the Cocoa frameworks, the language, and how it all fits together. But once I really "got" it, it was very very exciting.
It sounds cliché, but it's true. Stick it out.
Of course, if you're bringing in C++ libraries or existing C++ code, you can use those modules with Objective-C/Objective-C++.

I know its been a while since this question but I had the exact problem and solved it by disabling SMTP_BLOCK on csf.conf (we use CSF for a firewall).
To disable just edit csf.conf and disable SMTP_BLOCK like so:
###############################################################################
# SECTION:SMTP Settings
###############################################################################
# Block outgoing SMTP except for root, exim and mailman (forces scripts/users
# to use the exim/sendmail binary instead of sockets access). This replaces the
# protection as WHM > Tweak Settings > SMTP Tweaks
#
# This option uses the iptables ipt_owner/xt_owner module and must be loaded
# for it to work. It may not be available on some VPS platforms
#
# Note: Run /etc/csf/csftest.pl to check whether this option will function on
# this server
# SMTP_BLOCK = "1" --> this will cause phpmailer Connection timed out (110)
SMTP_BLOCK = "0"
Here if you are referring to my previous answers Here is an Update. 1. Compile would be removed from the dependencies after 2018.
a new version build Gradle is available.
Use the above-noted stuff it will help you to resolve the errors. It is needed for the developers who are working after March 2018. Also, maven update might be needed. All above answers will not work on the Android Studio 3.1. Hence Above code block is needed to be changed if you are using 3.1. See also I replaced compile by implementation.
Call me simple but I just declared a Variant and split the responsetext from my REST GET on the quote comma quote between each item, then got the value I wanted by looking for the last quote with InStrRev. I'm sure that's not as elegant as some of the other suggestions but it works for me.
varLines = Split(.responsetext, """,""")
strType = Mid(varLines(8), InStrRev(varLines(8), """") + 1)
Yaml and Json are the simplest and most commonly used file formats to store settings/config. PyYaml can be used to parse yaml. Json is already part of python from 2.5. Yaml is a superset of Json. Json will solve most uses cases except multi line strings where escaping is required. Yaml takes care of these cases too.
>>> import json
>>> config = {'handler' : 'adminhandler.py', 'timeoutsec' : 5 }
>>> json.dump(config, open('/tmp/config.json', 'w'))
>>> json.load(open('/tmp/config.json'))
{u'handler': u'adminhandler.py', u'timeoutsec': 5}
Yes, use -E -dM
options instead of -c.
Example (outputs them to stdout):
gcc -dM -E - < /dev/null
For C++
g++ -dM -E -x c++ - < /dev/null
From the gcc manual:
Instead of the normal output, generate a list of `#define' directives for all the macros defined during the execution of the preprocessor, including predefined macros. This gives you a way of finding out what is predefined in your version of the preprocessor. Assuming you have no file foo.h, the command
touch foo.h; cpp -dM foo.h
will show all the predefined macros.
If you use -dM without the -E option, -dM is interpreted as a synonym for -fdump-rtl-mach.
Expanding a bit on the answers from @Guru and @Ronnis, you can hide the sequence and make it look more like an auto-increment using a trigger, and have a procedure that does the insert for you and returns the generated ID as an out parameter.
create table batch(batchid number,
batchname varchar2(30),
batchtype char(1),
source char(1),
intarea number)
/
create sequence batch_seq start with 1
/
create trigger batch_bi
before insert on batch
for each row
begin
select batch_seq.nextval into :new.batchid from dual;
end;
/
create procedure insert_batch(v_batchname batch.batchname%TYPE,
v_batchtype batch.batchtype%TYPE,
v_source batch.source%TYPE,
v_intarea batch.intarea%TYPE,
v_batchid out batch.batchid%TYPE)
as
begin
insert into batch(batchname, batchtype, source, intarea)
values(v_batchname, v_batchtype, v_source, v_intarea)
returning batchid into v_batchid;
end;
/
You can then call the procedure instead of doing a plain insert, e.g. from an anoymous block:
declare
l_batchid batch.batchid%TYPE;
begin
insert_batch(v_batchname => 'Batch 1',
v_batchtype => 'A',
v_source => 'Z',
v_intarea => 1,
v_batchid => l_batchid);
dbms_output.put_line('Generated id: ' || l_batchid);
insert_batch(v_batchname => 'Batch 99',
v_batchtype => 'B',
v_source => 'Y',
v_intarea => 9,
v_batchid => l_batchid);
dbms_output.put_line('Generated id: ' || l_batchid);
end;
/
Generated id: 1
Generated id: 2
You can make the call without an explicit anonymous block, e.g. from SQL*Plus:
variable l_batchid number;
exec insert_batch('Batch 21', 'C', 'X', 7, :l_batchid);
... and use the bind variable :l_batchid
to refer to the generated value afterwards:
print l_batchid;
insert into some_table values(:l_batch_id, ...);

It is a common misconception that time (a measurable 4th dimension) is different over the world. Timestamp as a moment in time is unique. Date however is influenced how we "see" time but actually it is "time of day".
An example: two people look at the clock at the same moment. The timestamp is the same, right? But one of them is in London and sees 12:00 noon (GMT, timezone offset is 0), and the other is in Belgrade and sees 14:00 (CET, Central Europe, daylight saving now, offset is +2).
Their perception is different but the moment is the same.
You can find more details in this answer.
OK, it's not a duplicate of this question but it is pointless since you are confusing the terms "Timestamp = moment in time (objective)" and "Date[Time] = time of day (subjective)".
Let's look at your original question code broken down like this:
// Get the "original" value from database.
Timestamp momentFromDB = rs.getTimestamp("anytimestampcolumn");
// Turn it into a Joda DateTime with time zone.
DateTime dt = new DateTime(momentFromDB, DateTimeZone.forID("anytimezone"));
// And then turn it back into a timestamp but "with time zone".
Timestamp ts = new Timestamp(dt.getMillis());
I haven't run this code but I am certain it will print true
and the same number of milliseconds each time:
System.out.println("momentFromDB == dt : " + (momentFromDB.getTime() == dt.getTimeInMillis());
System.out.println("momentFromDB == ts : " + (momentFromDB.getTime() == ts.getTime()));
System.out.println("dt == ts : " + (dt.getTimeInMillis() == ts.getTime()));
System.out.println("momentFromDB [ms] : " + momentFromDB.getTime());
System.out.println("ts [ms] : " + ts.getTime());
System.out.println("dt [ms] : " + dt.getTimeInMillis());
But as you said yourself printing them out as strings will result in "different" time because DateTime
applies the time zone. That's why "time" is stored and transferred as Timestamp
objects (which basically wraps a long
) and displayed or entered as Date[Time]
.
In your own answer you are artificially adding an offset and creating a "wrong" time.
If you use that timestamp to create another DateTime
and print it out it will be offset twice.
// Turn it back into a Joda DateTime with time zone.
DateTime dt = new DateTime(ts, DateTimeZone.forID("anytimezone"));
P.S. If you have the time go through the very complex Joda Time source code to see how it holds the time (millis) and how it prints it.

NSParameterAssert(label != nil);
// create instances of NSLayoutManager, NSTextContainer and NSTextStorage
NSLayoutManager *layoutManager = [[NSLayoutManager alloc] init];
NSTextStorage *textStorage = [[NSTextStorage alloc] initWithAttributedString:label.attributedText];
// configure layoutManager and textStorage
[textStorage addLayoutManager:layoutManager];
// configure textContainer for the label
NSTextContainer *textContainer = [[NSTextContainer alloc] initWithSize:CGSizeMake(label.frame.size.width, label.frame.size.height)];
textContainer.lineFragmentPadding = 0.0;
textContainer.lineBreakMode = label.lineBreakMode;
textContainer.maximumNumberOfLines = label.numberOfLines;
// find the tapped character location and compare it to the specified range
CGPoint locationOfTouchInLabel = [gesture locationInView:label];
[layoutManager addTextContainer:textContainer]; //(move here, not sure it that matter that calling this line after textContainer is set
NSInteger indexOfCharacter = [layoutManager characterIndexForPoint:locationOfTouchInLabel

Showing the above explanations in action in a simple console program:

Console.WriteLine("Press any key to exit...");
Console.ReadLine();
}
public async static void TestAsyncAwaitMethods()
{
await LongRunningMethod();
}
public static async Task<int> LongRunningMethod()
{
Console.WriteLine("Starting Long Running method...");
await Task.Delay(5000);
Console.WriteLine("End Long Running method...");
return 1;
}
}
And the output is:
Starting Long Running method...
Press any key to exit...
End Long Running method...
Thus,
TestAsyncAwaitMethods
. That immediately returns without halting the current thread and we immediately see 'Press any key to exit' messageLongRunningMethod
is running in the background. Once its completed, another thread from Threadpool picks up this context and displays the final messageThus, not thread is blocked.
For anyone using Node, I found a nice and simple solution with ES6 imports and the cookie
module!
First install the cookie module (and save as a dependency):
npm install --save cookie
Then import and use:
import cookie from 'cookie';
let parsed = cookie.parse(document.cookie);
if('cookie1' in parsed)
console.log(parsed.cookie1);
Run this Command
alter user myuser with superuser;
If you want to see the permission to a user run following command

Try also with '--quit' option, which allows you to abort the current operation and further clear the sequencer state.
--quit Forget about the current operation in progress. Can be used to clear the sequencer state after a failed cherry-pick or revert.
--abort Cancel the operation and return to the pre-sequence state.
use help to see the original doc with more details, $ git help cherry-pick
I would avoid 'git reset --hard HEAD' that is too harsh and you might ended up doing some manual work.

Update:
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The HTML was a control for entering a date and time (hour, minute, second, and fraction of a second) as well as a timezone. This feature has been removed from WHATWG HTML, and is no longer supported in browsers.
Instead, browsers are implementing (and developers are encouraged to use) the datetime-local input type.
Why is HTML5 input type datetime removed from browsers already supporting it?

.NET 4+
IList<string> strings = new List<string>{"1","2","testing"};
string joined = string.Join(",", strings);
Detail & Pre .Net 4.0 Solutions
IEnumerable<string>
can be converted into a string array very easily with LINQ (.NET 3.5):
IEnumerable<string> strings = ...;
string[] array = strings.ToArray();
It's easy enough to write the equivalent helper method if you need to:
public static T[] ToArray(IEnumerable<T> source)
{
return new List<T>(source).ToArray();
}
Then call it like this:
IEnumerable<string> strings = ...;
string[] array = Helpers.ToArray(strings);
You can then call string.Join
. Of course, you don't have to use a helper method:
// C# 3 and .NET 3.5 way:
string joined = string.Join(",", strings.ToArray());
// C# 2 and .NET 2.0 way:
string joined = string.Join(",", new List<string>(strings).ToArray());
The latter is a bit of a mouthful though :)
This is likely to be the simplest way to do it, and quite performant as well - there are other questions about exactly what the performance is like, including (but not limited to) this one.
As of .NET 4.0, there are more overloads available in string.Join
, so you can actually just write:
string joined = string.Join(",", strings);
Much simpler :)
It just associates a semaphore with every object, and uses that.
The easiest way I've found to place objects on the left is using FlowLayout.

Use a different function, like VLOOKUP:
=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", VLOOKUP(A1,B:C,2,FALSE))
Another way would be adding __getitem__, __setitem__ function
def __getitem__(self, key):
return getattr(self, key)
You can use self[key] to access now.
This worked for me, no splicing or anything required:

</div>
JavaScript
var columnsPerRow = 4;
$scope.rows = function() {
return new Array(columnsPerRow);
};
$scope.indexInRange = function(columnIndex,rowIndex) {
return columnIndex >= (rowIndex * columnsPerRow) && columnIndex < (rowIndex * columnsPerRow) + columnsPerRow;
};

Maybe with Dispatch
:
from win32com.client import Dispatch
zk = Dispatch("zkemkeeper.ZKEM")
Where zkemkeeper is a registered DLL file on the system... After that, you can access functions just by calling them:
zk.Connect_Net(IP_address, port)
For methods which may fail, that is you specify boolean as return type, I would use the prefix try
:
if (tryCreateFreshSnapshot())
{
// ...
}
For all other cases use prefixes like is..
has..
was..
can..
allows..
..
Python is garbage-collected, so if you reduce the size of your list, it will reclaim memory. You can also use the "del" statement to get rid of a variable completely:

If you want to analyze a file uploaded by the user, the Flask quickstart shows how to get files from users and access them. Get the file from request.files
and pass it to the summary function.
from flask import request, jsonify
from werkzeug import secure_filename

def summary():
if request.method == 'POST':
csv = request.files['data']
return jsonify(
summary=make_summary(csv),
csv_name=secure_filename(csv.filename)
)
return render_template('submit_data.html')
Replace the 'data'
key for request.files
with the name of the file input in your HTML form.

. For example, pip
makes it easy to clone your site-packages by building a requirements file and then installing it with a single command on each side. Or to convert your requirements file to a local repo to use for in-house development. And so on.The only good reason that I know of to use easy_install
in 2015 is the special case of using Apple's pre-installed Python versions with OS X 10.5-10.8. Since 10.5, Apple has included easy_install
, but as of 10.10 they still don't include pip
. With 10.9+, you should still just use get-pip.py
, but for 10.5-10.8, this has some problems, so it's easier to sudo easy_install pip
. (In general, easy_install pip
is a bad idea; it's only for OS X 10.5-10.8 that you want to do this.) Also, 10.5-10.8 include readline
in a way that easy_install
knows how to kludge around but pip
doesn't, so you also want to sudo easy_install readline
if you want to upgrade that.

I hope you see this example helpful as it was for me along with the other answers.
That format requires you to use either:
CASE ebv.db_no
WHEN 22978 THEN 'WECS 9500'
WHEN 23218 THEN 'WECS 9500'
WHEN 23219 THEN 'WECS 9500'
ELSE 'WECS 9520'
END as wecs_system
Otherwise, use:
CASE
WHEN ebv.db_no IN (22978, 23218, 23219) THEN 'WECS 9500'
ELSE 'WECS 9520'
END as wecs_system
This should do it
For large files:
filenames = ['file1.txt', 'file2.txt', ...]
with open('path/to/output/file', 'w') as outfile:
for fname in filenames:
with open(fname) as infile:
for line in infile:
outfile.write(line)
For small files:
filenames = ['file1.txt', 'file2.txt', ...]
with open('path/to/output/file', 'w') as outfile:
for fname in filenames:
with open(fname) as infile:
outfile.write(infile.read())
… and another interesting one that I thought of:
filenames = ['file1.txt', 'file2.txt', ...]
with open('path/to/output/file', 'w') as outfile:
for line in itertools.chain.from_iterable(itertools.imap(open, filnames)):
outfile.write(line)
Sadly, this last method leaves a few open file descriptors, which the GC should take care of anyway. I just thought it was interesting
In order to use word-wrap: break-word
, you need to set a width (in px). For example:
div {
width: 250px;
word-wrap: break-word;
}
word-wrap is a CSS3 property, but it should work in all browsers, including IE 5.5-9.
This alternative also provides a back function.
The template:
<a ng-click='back()'>Back</a>
The module:
myModule.run(function ($rootScope, $location) {
var history = [];
$rootScope.$on('$routeChangeSuccess', function() {
history.push($location.$$path);
});
$rootScope.back = function () {
var prevUrl = history.length > 1 ? history.splice(-2)[0] : "/";
$location.path(prevUrl);
};
});
I believe your problem is that you are passing testFunct a string, and not a function object, (is that even possible?)
ScheduledThreadPoolExecutor
has this ability, but it's quite heavyweight.
Timer
also has this ability but opens several thread even if used only once.
Here's a simple implementation with a test (signature close to Android's Handler.postDelayed()):
public class JavaUtil {
public static void postDelayed(final Runnable runnable, final long delayMillis) {
final long requested = System.currentTimeMillis();
new Thread(new Runnable() {
@Override
public void run() {
// The while is just to ignore interruption.
while (true) {
try {
long leftToSleep = requested + delayMillis - System.currentTimeMillis();
if (leftToSleep > 0) {
Thread.sleep(leftToSleep);
}
break;
} catch (InterruptedException ignored) {
}
}
runnable.run();
}
}).start();
}
}
Test:
@Test
public void testRunsOnlyOnce() throws InterruptedException {
long delay = 100;
int num = 0;
final AtomicInteger numAtomic = new AtomicInteger(num);
JavaUtil.postDelayed(new Runnable() {
@Override
public void run() {
numAtomic.incrementAndGet();
}
}, delay);
Assert.assertEquals(num, numAtomic.get());
Thread.sleep(delay + 10);
Assert.assertEquals(num + 1, numAtomic.get());
Thread.sleep(delay * 2);
Assert.assertEquals(num + 1, numAtomic.get());
}
You can use the -B
and -A
to print lines before and after the match.
grep -i -B 10 'error' data
Will print the 10 lines before the match, including the matching line itself.
In my case, stopping Proxifier fixed it. I added a rule to route any connections from vpnkit.exe
as Direct

Because the case [2] document.myForm.foo
is a dialect from Internet Exploere.
So instead of it, I prefer document.forms.myForm.elements.foo
or document.forms["myForm"].elements["foo"]
.
With Winforms you can use Form.BackColor to do this.
From within the Form's code:
BackColor = Color.LightPink;
If you mean a WPF Window you can use the Background property.
From within the Window's code:
Background = Brushes.LightPink;

My version of the answer is actually very similar to the @Stefan Haustein. I found the answer on Android Developer page Retrieving File Information; the information here is even more condensed on this specific topic than on Storage Access Framework guide site. In the result from the query the column index containing file name is OpenableColumns.DISPLAY_NAME
. None of other answers/solutions for column indexes worked for me. Below is the sample function:
/**
* @param uri uri of file.
* @param contentResolver access to server app.
* @return the name of the file.
*/
def extractFileName(uri: Uri, contentResolver: ContentResolver): Option[String] = {
var fileName: Option[String] = None
if (uri.getScheme.equals("file")) {
fileName = Option(uri.getLastPathSegment)
} else if (uri.getScheme.equals("content")) {
var cursor: Cursor = null
try {
// Query the server app to get the file's display name and size.
cursor = contentResolver.query(uri, null, null, null, null)
// Get the column indexes of the data in the Cursor,
// move to the first row in the Cursor, get the data.
if (cursor != null && cursor.moveToFirst()) {
val nameIndex = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME)
fileName = Option(cursor.getString(nameIndex))
}
} finally {
if (cursor != null) {
cursor.close()
}
}
}
fileName
}
jQuery $.extend(obj1, obj2)
would merge 2 objects for you, but you should really be using an array.
var alertsObj = {

2: {app:'helloagain',message:'another message'}
};
var alertArr = [
{app:'helloworld','message'},
{app:'helloagain',message:'another message'}
];
var newAlert = {app:'new',message:'message'};
$.extend(alertsObj, newAlert);
alertArr.push(newAlert);

Simple one liner that I didn't found in answers:
Date date = Date.from(ZonedDateTime.parse("2010-01-01T12:00:00+01:00").toInstant());
Date doesn't contain timezone, it will be stored in UTC, but will be properly converted to your JVM timezone even during simple output with System.out.println(date)
.

As in your example, the fit_start_time
is not later than the fit_end_time
.
Try it the other way round:
var fit_start_time = $("#fit_start_time").val(); //2013-09-5
var fit_end_time = $("#fit_end_time").val(); //2013-09-10
if(Date.parse(fit_start_time) <= Date.parse(fit_end_time)){
alert("Please select a different End Date.");
}
Update
Your code implies that you want to see the alert
with the current variables you have. If this is the case then the above code is correct. If you're intention (as per the implication of the alert message
) is to make sure their fit_start_time
variable is a date that is before the fit_end_time
, then your original code is fine, but the data you're getting from the jQuery .val()
methods is not parsing correctly. It would help if you gave us the actual HTML which the selector is sniffing at.

I'm assuming you mean that 'use' means read, but what i'll explain for the read case can be basically reversed for the write case.
so you end up with a byte[]. this could represent any kind of data which may need special types of conversions (character, encrypted, etc). let's pretend you want to write this data as is to a file.
firstly you could create a ByteArrayInputStream which is basically a mechanism to supply the bytes to something in sequence.
then you could create a FileOutputStream for the file you want to create. there are many types of InputStreams and OutputStreams for different data sources and destinations.
lastly you would write the InputStream to the OutputStream. in this case, the array of bytes would be sent in sequence to the FileOutputStream for writing. For this i recommend using IOUtils
byte[] bytes = ...;//
ByteArrayInputStream in = new ByteArrayInputStream(bytes);
FileOutputStream out = new FileOutputStream(new File(...));
IOUtils.copy(in, out);
IOUtils.closeQuietly(in);
IOUtils.closeQuietly(out);
and in reverse
FileInputStream in = new FileInputStream(new File(...));
ByteArrayOutputStream out = new ByteArrayOutputStream();
IOUtils.copy(in, out);
IOUtils.closeQuietly(in);
IOUtils.closeQuietly(out);
byte[] bytes = out.toByteArray();
if you use the above code snippets you'll need to handle exceptions and i recommend you do the 'closes' in a finally block.
Can you change the if condition to this:
if (!is.na(comments[l])) print(comments[l]);
You can only check for NA values with is.na().
If all your divs start with editDialog as you stated, then you can use the following selector:
$("div[id^='editDialog']")
Or you could use a class selector instead if it's easier for you
<div id="editDialog-0" class="editDialog">...</div>
$(".editDialog")
Like it has been already mentioned, you are reading the file in binary mode and then creating a list of bytes. In your following for loop you are comparing string to bytes and that is where the code is failing.
Decoding the bytes while adding to the list should work. The changed code should look as follows:
with open(fname, 'rb') as f:
lines = [x.decode('utf8').strip() for x in f.readlines()]
The bytes type was introduced in Python 3 and that is why your code worked in Python 2. In Python 2 there was no data type for bytes:
>>> s=bytes('hello')
>>> type(s)
<type 'str'>
You must add your keyListener to every component that you need. Only the component with the focus will send these events. For instance, if you have only one TextBox in your JFrame, that TextBox has the focus. So you must add a KeyListener to this component as well.
The process is the same:
myComponent.addKeyListener(new KeyListener ...);
Note: Some components aren't focusable like JLabel.
For setting them to focusable you need to:
myComponent.setFocusable(true);
To make the code clear that you are intending to get the first row, CodeIgniter now allows you to use:
if ($query->num_rows() > 0) {
return $query->first_row();
}
To retrieve the first row.
This should help.
Integer startIn = null;
// (optional below but a good practice, to prevent errors.)
boolean dontContinue = false;
try {
Integer.parseInt (startField.getText());
} catch (NumberFormatException e){
e.printStackTrace();
}
// in java = assigns a boolean in if statements oddly.
// Thus double equal must be used. So if startIn is null, display the message
if (startIn == null) {
JOptionPane.showMessageDialog(null,
"You must enter a number between 0-16.","Input Error",
JOptionPane.ERROR_MESSAGE);
}
// (again optional)
if (dontContinue == true) {
//Do-some-error-fix
}
The code of exchange is below:
public <T> ResponseEntity<T> exchange(String url, HttpMethod method,
HttpEntity<?> requestEntity, Class<T> responseType, Object... uriVariables) throws RestClientException
Exception RestClientException
has HttpClientErrorException
and HttpStatusCodeException
exception.
So in RestTemplete
there may occure HttpClientErrorException
and HttpStatusCodeException
exception.
In exception object you can get exact error message using this way: exception.getResponseBodyAsString()
Here is the example code:
public Object callToRestService(HttpMethod httpMethod, String url, Object requestObject, Class<?> responseObject) {
printLog( "Url : " + url);
printLog( "callToRestService Request : " + new GsonBuilder().setPrettyPrinting().create().toJson(requestObject));
try {
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<Object> entity = new HttpEntity<>(requestObject, requestHeaders);
long start = System.currentTimeMillis();
ResponseEntity<?> responseEntity = restTemplate.exchange(url, httpMethod, entity, responseObject);
printLog( "callToRestService Status : " + responseEntity.getStatusCodeValue());
printLog( "callToRestService Body : " + new GsonBuilder().setPrettyPrinting().create().toJson(responseEntity.getBody()));
long elapsedTime = System.currentTimeMillis() - start;
printLog( "callToRestService Execution time: " + elapsedTime + " Milliseconds)");
if (responseEntity.getStatusCodeValue() == 200 && responseEntity.getBody() != null) {
return responseEntity.getBody();
}
} catch (HttpClientErrorException exception) {
printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
//Handle exception here
}catch (HttpStatusCodeException exception) {
printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
//Handle exception here
}
return null;
}
Here is the code description:
In this method you have to pass request and response class. This method will automatically parse response as requested object.
First of All you have to add message converter.
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
Then you have to add requestHeader
.
Here is the code:
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<Object> entity = new HttpEntity<>(requestObject, requestHeaders);
Finally, you have to call exchange method:
ResponseEntity<?> responseEntity = restTemplate.exchange(url, httpMethod, entity, responseObject);
For prety printing i used Gson library.
here is the gradle : compile 'com.google.code.gson:gson:2.4'
You can just call the bellow code to get response:
ResponseObject response=new RestExample().callToRestService(HttpMethod.POST,"URL_HERE",new RequestObject(),ResponseObject.class);
Here is the full working code:
import com.google.gson.GsonBuilder;
import org.springframework.http.*;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.client.HttpClientErrorException;
import org.springframework.web.client.HttpStatusCodeException;
import org.springframework.web.client.RestTemplate;
public class RestExample {
public RestExample() {
}
public Object callToRestService(HttpMethod httpMethod, String url, Object requestObject, Class<?> responseObject) {
printLog( "Url : " + url);
printLog( "callToRestService Request : " + new GsonBuilder().setPrettyPrinting().create().toJson(requestObject));
try {
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<Object> entity = new HttpEntity<>(requestObject, requestHeaders);
long start = System.currentTimeMillis();
ResponseEntity<?> responseEntity = restTemplate.exchange(url, httpMethod, entity, responseObject);
printLog( "callToRestService Status : " + responseEntity.getStatusCodeValue());
printLog( "callToRestService Body : " + new GsonBuilder().setPrettyPrinting().create().toJson(responseEntity.getBody()));
long elapsedTime = System.currentTimeMillis() - start;
printLog( "callToRestService Execution time: " + elapsedTime + " Milliseconds)");
if (responseEntity.getStatusCodeValue() == 200 && responseEntity.getBody() != null) {
return responseEntity.getBody();
}
} catch (HttpClientErrorException exception) {
printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
//Handle exception here
}catch (HttpStatusCodeException exception) {
printLog( "callToRestService Error :" + exception.getResponseBodyAsString());
//Handle exception here
}
return null;
}
private void printLog(String message){
System.out.println(message);
}
}
Thanks :)
i think it's pretty easy. just use this css
.content {
width: 100%;
height:(what u wanna give);
float: left;
position: fixed;
overflow: auto;
overflow-y: auto;
overflow-x: none;
}
after this just give this class to ur div just like -
<div class="content">your stuff goes in...</div>
function extractSummary(iCalContent) {
var rx = /\nSUMMARY:(.*)\n/g;
var arr = rx.exec(iCalContent);
return arr[1];
}
You need these changes:
Put the *
inside the parenthesis as
suggested above. Otherwise your matching
group will contain only one
character.
Get rid of the ^
and $
. With the global option they match on start and end of the full string, rather than on start and end of lines. Match on explicit newlines instead.
I suppose you want the matching group (what's
inside the parenthesis) rather than
the full array? arr[0]
is
the full match ("\nSUMMARY:..."
) and
the next indexes contain the group
matches.
String.match(regexp) is supposed to return an array with the matches. In my browser it doesn't (Safari on Mac returns only the full match, not the groups), but Regexp.exec(string) works.
Figured it out. The VM's in cloud engine don't come with a root password setup by default so you'll first need to change the password using
sudo passwd
If you do everything correctly, it should do something like this:
user@server[~]# sudo passwd
Changing password for user root.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
from random import randint
x = [randint(0, 9) for p in range(0, 10)]
This generates 10 pseudorandom integers in range 0 to 9 inclusive.
[Ljava.lang.Object;
is the name for Object[].class
, the java.lang.Class
representing the class of array of Object
.
The naming scheme is documented in Class.getName()
:
If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).
If this class object represents a primitive type or
void
, then the name returned is the Java language keyword corresponding to the primitive type orvoid
.If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more
'['
characters representing the depth of the array nesting. The encoding of element type names is as follows:Element Type Encoding boolean Z byte B char C double D float F int I long J short S class or interface Lclassname;
Yours is the last on that list. Here are some examples:
// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx
The reason why the toString()
method on arrays returns String
in this format is because arrays do not @Override
the method inherited from Object
, which is specified as follows:
The
toString
method for classObject
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:getClass().getName() + '@' + Integer.toHexString(hashCode())
Note: you can not rely on the toString()
of any arbitrary object to follow the above specification, since they can (and usually do) @Override
it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass()
on it (a final
method inherited from Object
) and then reflecting on the returned Class
object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).
toString
for arraysjava.util.Arrays
provides toString
overloads for primitive arrays and Object[]
. There is also deepToString
that you may want to use for nested arrays.
Here are some examples:
int[] nums = { 1, 2, 3 };
System.out.println(nums);
// [I@xxxxx
System.out.println(Arrays.toString(nums));
// [1, 2, 3]
int[][] table = {
{ 1, },
{ 2, 3, },
{ 4, 5, 6, },
};
System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]
System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]
There are also Arrays.equals
and Arrays.deepEquals
that perform array equality comparison by their elements, among many other array-related utility methods.

Erase the "pch.h"/"stdafx.h" field in "Precompiled Header File" for the EOF error at the end of the build for the project.
Then you can feel free to delete the pch./stdafx. files in your project
Width value doesn't take into account border or padding:
http://www.htmldog.com/reference/cssproperties/width/
You get 2px of padding in each side, plus 1px of border in each side.
100% + 2*(2px +1px) = 100% + 6px, which is more than the 100% child-content the parent td has.
You have the option of:
box-sizing: border-box;
as per @pricco's answer;Use Jquery functions
<Button id="myPselector" data-id="1234">HI</Button>
console.log($("#myPselector").attr('data-id'));
You can append array of Data at the end of custom state:
const [vehicleData, setVehicleData] = React.useState<any[]>([]);
setVehicleData(old => [...old, ...newArrayData]);
For example, In below, you appear an example of axios:
useEffect(() => {
const fetchData = async () => {
const result = await axios(
{
url: `http://localhost:4000/api/vehicle?page=${page + 1}&pageSize=10`,
method: 'get',
}
);
setVehicleData(old => [...old, ...result.data.data]);
};
fetchData();
}, [page]);
You have to put a g
at the end, it stands for "global":
echo dog dog dos | sed -r 's:dog:log:g'

I wrote a similar answer to a similar question on Stack Overflow, but here is part of that answer.
The new version of Android Studio (2.1) has support for Java 8 features. Here is an extract from the Android Developers blogspot post:
... Android Studio 2.1 release includes support for the new Jack compiler and support for Java 8.
...
To use Java 8 language features when developing with the N Developer Preview, you need to use the Jack compiler. The New Project Wizard [File? New? Project] generates the correct configurations for projects targeting the N.
Android does not support Java 1.8 yet (it only supports up to 1.7), so you cannot use Java 8 features like lambdas.
This answer gives more detail on Android Studio's compatibility; it states:
If you want to use lambdas, one of the major features of Java 8 in Android, you can use gradle-retrolamba
If you want to know more about using gradle-retrolambda
, this answer gives a lot of detail on doing that.
If you want to cancel pending requests on stateChangeStart with ui-router, you can use something like this:
// in service
var deferred = $q.defer();
var scope = this;
$http.get(URL, {timeout : deferred.promise, cancel : deferred}).success(function(data){
//do something
deferred.resolve(dataUsage);
}).error(function(){
deferred.reject();
});
return deferred.promise;
// in UIrouter config
$rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
//To cancel pending request when change state
angular.forEach($http.pendingRequests, function(request) {
if (request.cancel && request.timeout) {
request.cancel.resolve();
}
});
});
