I was having problems here (i.e. sending form-data whilst uploading a file) until I used the following:
files = {'file': (filename, open(filepath, 'rb'), 'text/xml'),
'Content-Disposition': 'form-data; name="file"; filename="' + filename + '"',
'Content-Type': 'text/xml'}
That's the input that ended up working for me. In Chrome Dev Tools -> Network tab, I clicked the request I was interested in. In the Headers tab, there's a Form Data section, and it showed both the Content-Disposition and the Content-Type headers being set there.
I did NOT need to set headers in the actual requests.post() command for this to succeed (including them actually caused it to fail)
I solve this problem from a different perspective.
I think if the server sends JSON data with Content-Type: text/html
header. It doesn't mean the server guy intended to send you some html but accidentally changed to JSON. It does mean the server guy just doesn't care about what the Content-Type
header is. So if the server guy doesn't care as the client side you better ignore the Content-Type
header as well. To ignore the Content-Type
header check in AFNetworking
manager.responseSerializer.acceptableContentTypes = nil;
In this way the AFJSONResponseSerializer
(the default one) will serialize the JSON data without checking Content-Type
in response header.
The Expires entity-header field gives the date/time after which the response is considered stale.The Cache-control:maxage field gives the age value (in seconds) bigger than which response is consider stale.
Althought above header field give a mechanism to client to decide whether to send request to the server. In some condition, the client send a request to sever and the age value of response is bigger then the maxage value ,dose it means server needs to send the resource to client? Maybe the resource never changed.
In order to resolve this problem, HTTP1.1 gives last-modifided head. The server gives the last modified date of the response to client. When the client need this resource, it will send If-Modified-Since head field to server. If this date is before the modified date of the resouce, the server will sends the resource to client and gives 200 code.Otherwise,it will returns 304 code to client and this means client can use the resource it cached.
Try to look at http.get and response headers.
var http = require("http");
var options = {
host: 'stackoverflow.com',
port: 80,
path: '/'
};
http.get(options, function(res) {
console.log("Got response: " + res.statusCode);
for(var item in res.headers) {
console.log(item + ": " + res.headers[item]);
}
}).on('error', function(e) {
console.log("Got error: " + e.message);
});
I found solution for Spring 3.1. with using @ResponseBody annotation. Here is example of controller using Json output:
@RequestMapping(value = "/getDealers", method = RequestMethod.GET,
produces = "application/json; charset=utf-8")
@ResponseBody
public String sendMobileData() {
}
You can use "Empty Img Element".
Empty Img Element - document.createElement("img")
[HTML Code]
<div id="hello" draggable="true">Drag!!!</div>
[JavaScript Code]
var block = document.querySelector('#hello');
block.addEventListener('dragstart', function(e){
var img = document.createElement("img");
e.dataTransfer.setDragImage(img, 0, 0);
})
I come across this issue myself and I performed the steps below to reuse my ExceptionController
that is annotated with @ControllerAdvise
for Exceptions
thrown in a registered Filter.
There are obviously many ways to handle exception but, in my case, I wanted the exception to be handled by my ExceptionController
because I am stubborn and also because I don't want to copy/paste the same code (i.e. I have some processing/logging code in ExceptionController
). I would like to return the beautiful JSON
response just like the rest of the exceptions thrown not from a Filter.
{
"status": 400,
"message": "some exception thrown when executing the request"
}
Anyway, I managed to make use of my ExceptionHandler
and I had to do a little bit of extra as shown below in steps:
Steps
@ControllerAdvise
i.e. MyExceptionControllerSample code
//sample Filter, to be added in web.xml
public MyFilterThatThrowException implements Filter {
//Spring Controller annotated with @ControllerAdvise which has handlers
//for exceptions
private MyExceptionController myExceptionController;
@Override
public void destroy() {
// TODO Auto-generated method stub
}
@Override
public void init(FilterConfig arg0) throws ServletException {
//Manually get an instance of MyExceptionController
ApplicationContext ctx = WebApplicationContextUtils
.getRequiredWebApplicationContext(arg0.getServletContext());
//MyExceptionHanlder is now accessible because I loaded it manually
this.myExceptionController = ctx.getBean(MyExceptionController.class);
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
try {
//code that throws exception
} catch(Exception ex) {
//MyObject is whatever the output of the below method
MyObject errorDTO = myExceptionController.handleMyException(req, ex);
//set the response object
res.setStatus(errorDTO .getStatus());
res.setContentType("application/json");
//pass down the actual obj that exception handler normally send
ObjectMapper mapper = new ObjectMapper();
PrintWriter out = res.getWriter();
out.print(mapper.writeValueAsString(errorDTO ));
out.flush();
return;
}
//proceed normally otherwise
chain.doFilter(request, response);
}
}
And now the sample Spring Controller that handles Exception
in normal cases (i.e. exceptions that are not usually thrown in Filter level, the one we want to use for exceptions thrown in a Filter)
//sample SpringController
@ControllerAdvice
public class ExceptionController extends ResponseEntityExceptionHandler {
//sample handler
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
@ExceptionHandler(SQLException.class)
public @ResponseBody MyObject handleSQLException(HttpServletRequest request,
Exception ex){
ErrorDTO response = new ErrorDTO (400, "some exception thrown when "
+ "executing the request.");
return response;
}
//other handlers
}
Sharing the solution with those who wish to use ExceptionController
for Exceptions
thrown in a Filter.
First you should try with Proguard (This clean all code unused)
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
Assuming
source data range is A1:B100.
query cell is D1 (here you will input Police or Fire).
result cell is E1
Formula in E1 = VLOOKUP(D1, A1:B100, 2, FALSE)
use a simple formula: WHO.WHAT = VALUE
where,
WHO is the element in the storyboard you want to make changes to for eg. label
WHAT is the property of that element you wish to change for eg. text
VALUE is the change that you wish to be displayed
for eg. if I want to change the text from story text to You see a fork in the road in the label as shown in screenshot 1
In this case, our WHO is the label (element in the storyboard), WHAT is the text (property of element) and VALUE will be You see a fork in the road
so our final code will be as follows: Final code
screenshot 1 changes to screenshot 2 once the above code is executed.
I hope this solution helps you solve your issue. Thank you!
From ES2016 you can also use slightly better / easier / more elegant method (case-sensitive):
if (referrer.includes("Ral")) { ... }
or (case-insensitive):
if (referrer.toLowerCase().includes(someString.toLowerCase())) { ... }
Here is some comparison of .indexOf()
and .includes()
:
https://dev.to/adroitcoder/includes-vs-indexof-in-javascript
for (Tweet : tweets){ ...
should really be
for(Tweet tweet: tweets){...
Redirect standard error. For instance, if you're using bash on a unix machine, you can redirect standard error to /dev/null like this:
find . 2>/dev/null >files_and_folders
You can simply specify a series of images like this:
\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}
This will produce three slides with the images A to C in exactly the same position.
>>> t
[1, 3, 6]
>>> [j-i for i, j in zip(t[:-1], t[1:])] # or use itertools.izip in py2k
[2, 3]
I used 10.0.2.2 successfully on my home machine, but at work, it did not work. After hours of fooling around, I created a new emulator instance using the Android Virtual Device (AVD) manager, and finally the 10.0.2.2 worked.
I don't know what was wrong with the other emulator instance (the platform was the same), but if you find 10.0.2.2 does not work, try creating a new emulator instance.
For people with only one IP address and multiple sites on one server, you can configure IIS to listen on a port other than 80
, e.g 8080
by setting the TCP port in the properties of each of its sites (including the default one).
In Apache, enable mod_proxy
and mod_proxy_http
, then add a catch-all VirtualHost (after all others) so that requests Apache isn't explicitly handling get "forwarded" on to IIS.
<VirtualHost *:80>
ServerName foo.bar
ServerAlias *
ProxyPreserveHost On
ProxyPass / http://127.0.0.1:8080/
</VirtualHost>
Now you can have Apache serve some sites and IIS serve others, with no visible difference to the user.
Edit: your IIS sites must not include their port number in any URLs within their responses, including headers.
And for those of you who are here because you want to remove all gems with a certain prefix (ahem I'm looking at you aws-sdk!) you can run something like this:
gem list --no-version | grep "aws-sdk-" | xargs gem uninstall -aIx
Obviously put in your query instead of aws-sdk-
. You need the -I
in there to ignore dependencies.
Adopted form Ando's earlier answer
Using Jquery
$('<form/>', { action: url, method: 'POST' }).append(
$('<input>', {type: 'hidden', id: 'id_field_1', name: 'name_field_1', value: val_field_1}),
$('<input>', {type: 'hidden', id: 'id_field_2', name: 'name_field_2', value: val_field_2}),
).appendTo('body').submit();
The answer is NEVER! (unless you really know what you're doing)
9/10 times the solution can be resolved with a proper understanding of encoding/decoding.
1/10 people have an incorrectly defined locale or environment and need to set:
PYTHONIOENCODING="UTF-8"
in their environment to fix console printing problems.
(struck through to avoid re-use) changes the default encoding/decoding used whenever Python 2.x needs to convert a Unicode() to a str() (and vice-versa) and the encoding is not given. I.e:sys.setdefaultencoding("utf-8")
str(u"\u20AC")
unicode("€")
"{}".format(u"\u20AC")
In Python 2.x, the default encoding is set to ASCII and the above examples will fail with:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 0: ordinal not in range(128)
(My console is configured as UTF-8, so "€" = '\xe2\x82\xac'
, hence exception on \xe2
)
or
UnicodeEncodeError: 'ascii' codec can't encode character u'\u20ac' in position 0: ordinal not in range(128)
will allow these to work for me, but won't necessarily work for people who don't use UTF-8. The default of ASCII ensures that assumptions of encoding are not baked into codesys.setdefaultencoding("utf-8")
also has a side effect of appearing to fix sys.setdefaultencoding("utf-8")
sys.stdout.encoding
, used when printing characters to the console. Python uses the user's locale (Linux/OS X/Un*x) or codepage (Windows) to set this. Occasionally, a user's locale is broken and just requires PYTHONIOENCODING
to fix the console encoding.
Example:
$ export LANG=en_GB.gibberish
$ python
>>> import sys
>>> sys.stdout.encoding
'ANSI_X3.4-1968'
>>> print u"\u20AC"
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\u20ac' in position 0: ordinal not in range(128)
>>> exit()
$ PYTHONIOENCODING=UTF-8 python
>>> import sys
>>> sys.stdout.encoding
'UTF-8'
>>> print u"\u20AC"
€
People have been developing against Python 2.x for 16 years on the understanding that the default encoding is ASCII. UnicodeError
exception handling methods have been written to handle string to Unicode conversions on strings that are found to contain non-ASCII.
From https://anonbadger.wordpress.com/2015/06/16/why-sys-setdefaultencoding-will-break-code/
def welcome_message(byte_string):
try:
return u"%s runs your business" % byte_string
except UnicodeError:
return u"%s runs your business" % unicode(byte_string,
encoding=detect_encoding(byte_string))
print(welcome_message(u"Angstrom (Å®)".encode("latin-1"))
Previous to setting defaultencoding this code would be unable to decode the “Å” in the ascii encoding and then would enter the exception handler to guess the encoding and properly turn it into unicode. Printing: Angstrom (Å®) runs your business. Once you’ve set the defaultencoding to utf-8 the code will find that the byte_string can be interpreted as utf-8 and so it will mangle the data and return this instead: Angstrom (U) runs your business.
Changing what should be a constant will have dramatic effects on modules you depend upon. It's better to just fix the data coming in and out of your code.
While the setting of defaultencoding to UTF-8 isn't the root cause in the following example, it shows how problems are masked and how, when the input encoding changes, the code breaks in an unobvious way: UnicodeDecodeError: 'utf8' codec can't decode byte 0x80 in position 3131: invalid start byte
What is Looper?
Looper is a class which is used to execute the Messages(Runnables) in a queue. Normal threads have no such queue, e.g. simple thread does not have any queue. It executes once and after method execution finishes, the thread will not run another Message(Runnable).
Where we can use Looper class?
If someone wants to execute multiple messages(Runnables) then he should use the Looper class which is responsible for creating a queue in the thread. For example, while writing an application that downloads files from the internet, we can use Looper class to put files to be downloaded in the queue.
How it works?
There is prepare()
method to prepare the Looper. Then you can use loop()
method to create a message loop in the current thread and now your Looper is ready to execute the requests in the queue until you quit the loop.
Here is the code by which you can prepare the Looper.
class LooperThread extends Thread {
public Handler mHandler;
@Override
public void run() {
Looper.prepare();
mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
// process incoming messages here
}
};
Looper.loop();
}
}
Our development image only has the Tomcat service installation on it, so setting the environment variables, etc., didn't have any effect. If you need to do this through the Tomcat Windows service, there are a few things you'll need to be aware of:

A catch-all jQuery custom event based on an extension of it's core methods like it was proposed by different people in this thread:
(function() {
var ev = new $.Event('event.css.jquery'),
css = $.fn.css,
show = $.fn.show,
hide = $.fn.hide;
// extends css()
$.fn.css = function() {
css.apply(this, arguments);
$(this).trigger(ev);
};
// extends show()
$.fn.show = function() {
show.apply(this, arguments);
$(this).trigger(ev);
};
// extends hide()
$.fn.hide = function() {
hide.apply(this, arguments);
$(this).trigger(ev);
};
})();
An external library then, uses sth like $('selector').css('property', value)
.
As we don't want to alter the library's code but we DO want to extend it's behavior we do sth like:
$('#element').on('event.css.jquery', function(e) {
// ...more code here...
});
Example: user clicks on a panel that is built by a library. The library shows/hides elements based on user interaction. We want to add a sensor that shows that sth has been hidden/shown because of that interaction and should be called after the library's function.
Another example: jsfiddle.

The error raised here is in importing the python module. This can be solved by adding the python site-packages folder to the environment variable $PYTHONPATH on OS X. So we can add the following command to the .bash_profile file:
export PYTHONPATH="$PYTHONPATH:/usr/local/lib/pythonx.x/site-packages/"
*replace x.x with the python version you are using
Errors and exceptions in PowerShell are structured objects. The error message you see printed on the console is actually a formatted message with information from several elements of the error/exception object. You can (re-)construct it yourself like this:
$formatstring = "{0} : {1}`n{2}`n" +
" + CategoryInfo : {3}`n" +
" + FullyQualifiedErrorId : {4}`n"
$fields = $_.InvocationInfo.MyCommand.Name,
$_.ErrorDetails.Message,
$_.InvocationInfo.PositionMessage,
$_.CategoryInfo.ToString(),
$_.FullyQualifiedErrorId
$formatstring -f $fields
If you just want the error message displayed in your catch
block you can simply echo the current object variable (which holds the error at that point):
try {
...
} catch {
$_
}
If you need colored output use Write-Host
with a formatted string as described above:
try {
...
} catch {
...
Write-Host -Foreground Red -Background Black ($formatstring -f $fields)
}
With that said, usually you don't want to just display the error message as-is in an exception handler (otherwise the -ErrorAction Stop
would be pointless). The structured error/exception objects provide you with additional information that you can use for better error control. For instance you have $_.Exception.HResult
with the actual error number. $_.ScriptStackTrace
and $_.Exception.StackTrace
, so you can display stacktraces when debugging. $_.Exception.InnerException
gives you access to nested exceptions that often contain additional information about the error (top level PowerShell errors can be somewhat generic). You can unroll these nested exceptions with something like this:
$e = $_.Exception
$msg = $e.Message
while ($e.InnerException) {
$e = $e.InnerException
$msg += "`n" + $e.Message
}
$msg
In your case the information you want to extract seems to be in $_.ErrorDetails.Message
. It's not quite clear to me if you have an object or a JSON string there, but you should be able to get information about the types and values of the members of $_.ErrorDetails
by running
$_.ErrorDetails | Get-Member
$_.ErrorDetails | Format-List *
If $_.ErrorDetails.Message
is an object you should be able to obtain the message string like this:
$_.ErrorDetails.Message.message
otherwise you need to convert the JSON string to an object first:
$_.ErrorDetails.Message | ConvertFrom-Json | Select-Object -Expand message
Depending what kind of error you're handling, exceptions of particular types might also include more specific information about the problem at hand. In your case for instance you have a WebException
which in addition to the error message ($_.Exception.Message
) contains the actual response from the server:
PS C:\> $e.Exception | Get-Member TypeName: System.Net.WebException Name MemberType Definition ---- ---------- ---------- Equals Method bool Equals(System.Object obj), bool _Exception.E... GetBaseException Method System.Exception GetBaseException(), System.Excep... GetHashCode Method int GetHashCode(), int _Exception.GetHashCode() GetObjectData Method void GetObjectData(System.Runtime.Serialization.S... GetType Method type GetType(), type _Exception.GetType() ToString Method string ToString(), string _Exception.ToString() Data Property System.Collections.IDictionary Data {get;} HelpLink Property string HelpLink {get;set;} HResult Property int HResult {get;} InnerException Property System.Exception InnerException {get;} Message Property string Message {get;} Response Property System.Net.WebResponse Response {get;} Source Property string Source {get;set;} StackTrace Property string StackTrace {get;} Status Property System.Net.WebExceptionStatus Status {get;} TargetSite Property System.Reflection.MethodBase TargetSite {get;}
which provides you with information like this:
PS C:\> $e.Exception.Response IsMutuallyAuthenticated : False Cookies : {} Headers : {Keep-Alive, Connection, Content-Length, Content-T...} SupportsHeaders : True ContentLength : 198 ContentEncoding : ContentType : text/html; charset=iso-8859-1 CharacterSet : iso-8859-1 Server : Apache/2.4.10 LastModified : 17.07.2016 14:39:29 StatusCode : NotFound StatusDescription : Not Found ProtocolVersion : 1.1 ResponseUri : http://www.example.com/ Method : POST IsFromCache : False
Since not all exceptions have the exact same set of properties you may want to use specific handlers for particular exceptions:
try {
...
} catch [System.ArgumentException] {
# handle argument exceptions
} catch [System.Net.WebException] {
# handle web exceptions
} catch {
# handle all other exceptions
}
If you have operations that need to be done regardless of whether an error occured or not (cleanup tasks like closing a socket or a database connection) you can put them in a finally
block after the exception handling:
try {
...
} catch {
...
} finally {
# cleanup operations go here
}
My full example is here, but I will provide a summary below.
Layout
Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).
Make the swift file the xib file's owner.
Add the following code to the .swift file and hook up the outlets and actions from the .xib file.
import UIKit
class ResuableCustomView: UIView {
let nibName = "ReusableCustomView"
var contentView: UIView?
@IBOutlet weak var label: UILabel!
@IBAction func buttonTap(_ sender: UIButton) {
label.text = "Hi"
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
guard let view = loadViewFromNib() else { return }
view.frame = self.bounds
self.addSubview(view)
contentView = view
}
func loadViewFromNib() -> UIView? {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: nibName, bundle: bundle)
return nib.instantiate(withOwner: self, options: nil).first as? UIView
}
}
Use it
Use your custom view anywhere in your storyboard. Just add a UIView
and set the class name to your custom class name.
For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.
MyCustomClass.swift
MyCustomClass.xib
File's Owner
of the .xib file to be your custom class (MyCustomClass
)class
value (under the identity Inspector
) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.Assistant Editor
.
Connections Inspector
you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass
), but rather reference File's Owner
. Since File's Owner
is specified to be your custom class, the outlets will hook up and work propery. NibLoadable
protocol referenced below.
.swift
file name is different from your .xib
file name, then set the nibName
property to be the name of your .xib
file.required init?(coder aDecoder: NSCoder)
and override init(frame: CGRect)
to call setupFromNib()
like the example below.MyCustomClass
).Here is the protocol you will want to reference:
public protocol NibLoadable {
static var nibName: String { get }
}
public extension NibLoadable where Self: UIView {
public static var nibName: String {
return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
}
public static var nib: UINib {
let bundle = Bundle(for: Self.self)
return UINib(nibName: Self.nibName, bundle: bundle)
}
func setupFromNib() {
guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
addSubview(view)
view.translatesAutoresizingMaskIntoConstraints = false
view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
}
}
And here is an example of MyCustomClass
that implements the protocol (with the .xib file being named MyCustomClass.xib
):
@IBDesignable
class MyCustomClass: UIView, NibLoadable {
@IBOutlet weak var myLabel: UILabel!
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setupFromNib()
}
override init(frame: CGRect) {
super.init(frame: frame)
setupFromNib()
}
}
NOTE: If you miss the Gotcha and set the class
value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS
error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder)
method which then calls Self.nib.instantiate
and calls the init
again.
Local storage: It keeps store the user information data without expiration date this data will not be deleted when user closed the browser windows it will be available for day, week, month and year.
In Local storage can store 5-10mb offline data.
//Set the value in a local storage object
localStorage.setItem('name', myName);
//Get the value from storage object
localStorage.getItem('name');
//Delete the value from local storage object
localStorage.removeItem(name);//Delete specifice obeject from local storege
localStorage.clear();//Delete all from local storege
Session Storage: It is same like local storage date except it will delete all windows when browser windows closed by a web user.
In Session storage can store upto 5 mb data
//set the value to a object in session storege
sessionStorage.myNameInSession = "Krishna";
Session: A session is a global variable stored on the server. Each session is assigned a unique id which is used to retrieve stored values.
Cookies: Cookies are data, stored in small text files as name-value pairs, on your computer. Once a cookie has been set, all page requests that follow return the cookie name and value.

Just take out the fade
class from the modal div.
Specifically, change:
<div class="modal fade hide">
to:
<div class="modal hide">
UPDATE: For bootstrap3, the hide
class is not needed.
Shouldn't it be just the .list-group
? See below,
<ul class="list-group">
<li class="list-group-item active">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>

I was having a similar issue like yours, except that I wanted a specific subset of 'ancestry'. Hong Ning's query was a good start, except it will return combined records containing duplicates and/or extra ancestries (e.g. it would also return someone with ancestries ('England', 'France', 'Germany', 'Netherlands') and ('England', 'France', 'England'). Supposing you'd want just the three and only the three, you'd need the following query:
SELECT Src.user_id
FROM yourtable Src
WHERE ancestry in ('England', 'France', 'Germany')
AND EXISTS (
SELECT user_id
FROM dbo.yourtable
WHERE user_id = Src.user_id
GROUP BY user_id
HAVING COUNT(DISTINCT ancestry) = 3
)
GROUP BY user_id
HAVING COUNT(DISTINCT ancestry) = 3
I recommend to read this entire article, but here is the most relevant section that addresses your question:
Rollback and Error Handling is Difficult
In my articles on Error and Transaction Handling in SQL Server, I suggest that > you should always have an error handler like
BEGIN CATCH
IF @@trancount > 0 ROLLBACK TRANSACTION
EXEC error_handler_sp
RETURN 55555
END CATCH
The idea is that even if you do not start a transaction in the procedure, you should always include a ROLLBACK, because if you were not able to fulfil your contract, the transaction is not valid.
Unfortunately, this does not work well with INSERT-EXEC. If the called procedure executes a ROLLBACK statement, this happens:
Msg 3915, Level 16, State 0, Procedure SalesByStore, Line 9 Cannot use the ROLLBACK statement within an INSERT-EXEC statement.
The execution of the stored procedure is aborted. If there is no CATCH handler anywhere, the entire batch is aborted, and the transaction is rolled back. If the INSERT-EXEC is inside TRY-CATCH, that CATCH handler will fire, but the transaction is doomed, that is, you must roll it back. The net effect is that the rollback is achieved as requested, but the original error message that triggered the rollback is lost. That may seem like a small thing, but it makes troubleshooting much more difficult, because when you see this error, all you know is that something went wrong, but you don't know what.
There are several Reflection APIs which return classes but these may only be accessed if a Class has already been obtained either directly or indirectly.
Class.getSuperclass() Returns the super class for the given class. Class c = javax.swing.JButton.class.getSuperclass(); The super class of javax.swing.JButton is javax.swing.AbstractButton. Class.getClasses()
Returns all the public classes, interfaces, and enums that are members of the class including inherited members.
Class<?>[] c = Character.class.getClasses();
Character contains two member classes Character.Subset and
Character.UnicodeBlock.Class.getDeclaredClasses() Returns all of the classes interfaces, and enums that are explicitly declared in this class. Class<?>[] c = Character.class.getDeclaredClasses(); Character contains two public member classes Character.Subset and Character.UnicodeBlock and one private class
Character.CharacterCache.
Class.getDeclaringClass() java.lang.reflect.Field.getDeclaringClass() java.lang.reflect.Method.getDeclaringClass() java.lang.reflect.Constructor.getDeclaringClass() Returns the Class in which these members were declared. Anonymous Class Declarations will not have a declaring class but will
have an enclosing class.
import java.lang.reflect.Field; Field f = System.class.getField("out"); Class c = f.getDeclaringClass(); The field out is declared in System. public class MyClass { static Object o = new Object() { public void m() {} }; static Class<c> = o.getClass().getEnclosingClass(); } The declaring class of the anonymous class defined by o is null. Class.getEnclosingClass() Returns the immediately enclosing class of the class. Class c = Thread.State.class().getEnclosingClass(); The enclosing class of the enum Thread.State is Thread. public class MyClass { static Object o = new Object() { public void m() {} }; static Class<c> = o.getClass().getEnclosingClass(); } The anonymous class defined by o is enclosed by MyClass.
Suggestions:
true
would allow appending text into the File if it exists. println(...)
on your PrintWriter, writing your new text into the file.close()
of the PrintWriter should be in the try's finally block.e.g.,
PrintWriter pw = null;
try {
File file = new File("fubars.txt");
FileWriter fw = new FileWriter(file, true);
pw = new PrintWriter(fw);
pw.println("Fubars rule!");
} catch (IOException e) {
e.printStackTrace();
} finally {
if (pw != null) {
pw.close();
}
}
Easy, no?

It worked for me now!
Thank goodness I found this. The following is extremely important:
<meta http-equiv="X-UA-Compatible" content="IE=9" >
Without this, none of the reports I'd been generating would work post IE9 install despite having worked great in IE8. They would show up properly in a web browser control, but there would be missing letters, jacked up white space, etc, when I called .Print(). They were just basic HTML that should be capable of being rendered even in Mosaic. heh Not sure why the IE7 compatibility mode was going haywire. Notably, you could .Print() the same page 5 times and have it be missing different letters each time. It would even carry over into PDF output, so it's definitely the browser.
I was able to solve the issue by granting complete s3 access to Lambda from policies. Make a new role for Lambda and attach the policy with complete S3 Access to it.
Hope this will help.
One-liner:
if (!dir.exists(output_dir)) {dir.create(output_dir)}
Example:
dateDIR <- as.character(Sys.Date())
outputDIR <- file.path(outD, dateDIR)
if (!dir.exists(outputDIR)) {dir.create(outputDIR)}
You can add a style directly to the select element:
<select name="foo" style="width: 200px">
So this select item will be 200 pixels wide.
Alternatively you can apply a class or id to the element and reference it in a stylesheet
Since you are disabling it in the first place, the way to enable it is to set its disabled
property as false
.
To change its disabled
property in Javascript, you use this:
var btn = document.getElementById("Button");
btn.disabled = false;
And obviously to disable it again, you'd use true
instead.
Since you also tagged the question with jQuery, you could use the .prop
method. Something like:
var btn = $("#Button");
btn.prop("disabled", true); // Or `false`
This is in the newer versions of jQuery. The older way to do this is to add or remove an attribute like so:
var btn = $("#Button");
btn.attr("disabled", "disabled");
// or
btn.removeAttr("disabled");
The mere presence of the disabled
property disables the element, so you cannot set its value as "false". Even the following should disable the element
<input type="button" value="Submit" disabled="" />
You need to either remove the attribute completely or set its property.
You can change the comment character to something besides # like this:
git config --global core.commentchar "@"
Since you are having trouble adjusting the height you might be able to use this. http://jsfiddle.net/uf9bx/1/
img{
width: 100%;
height: 100%;
max-height: 300px;
}
I'm not sure exactly what size or location you are putting your images but maybe this will help!
There several different ways to do it. But You can use the following approach:
List<DataRow> RowsToDelete = new List<DataRow>();
for (int i = 0; i < drr.Length; i++)
{
if(condition to delete the row)
{
RowsToDelete.Add(drr[i]);
}
}
foreach(var dr in RowsToDelete)
{
drr.Rows.Remove(dr);
}
Our server calls stored procs from Java like so - works on both SQL Server 2000 & 2008:
String SPsql = "EXEC <sp_name> ?,?"; // for stored proc taking 2 parameters
Connection con = SmartPoolFactory.getConnection(); // java.sql.Connection
PreparedStatement ps = con.prepareStatement(SPsql);
ps.setEscapeProcessing(true);
ps.setQueryTimeout(<timeout value>);
ps.setString(1, <param1>);
ps.setString(2, <param2>);
ResultSet rs = ps.executeQuery();
You can do
JLabel l = new JLabel("<html><p>Hello World! blah blah blah</p></html>", SwingConstants.CENTER);
and it will automatically wrap it where appropriate.
If you're looking for a way of applying the "static" keyword to a class, like you can in C# for example, then you won't be able to without using Managed C++.
But the looks of your sample, you just need to create a public static method on your BitParser object. Like so:
BitParser.h
class BitParser
{
public:
static bool getBitAt(int buffer, int bitIndex);
// ...lots of great stuff
private:
// Disallow creating an instance of this object
BitParser() {}
};
BitParser.cpp
bool BitParser::getBitAt(int buffer, int bitIndex)
{
bool isBitSet = false;
// .. determine if bit is set
return isBitSet;
}
You can use this code to call the method in the same way as your example code.
Hope that helps! Cheers.
Hmm, from the examples you gave it seems like "$_SERVER['REQUEST_URI']" and the explode() function could help you. You could use explode to break up the URL following the domain name into an array, separating it at each forward-slash.
As a very basic example, something like this could be implemented:
$crumbs = explode("/",$_SERVER["REQUEST_URI"]);
foreach($crumbs as $crumb){
echo ucfirst(str_replace(array(".php","_"),array(""," "),$crumb) . ' ');
}
SIGTERM is used to restart Apache (provided that it's setup in init to auto-restart): http://httpd.apache.org/docs/2.2/stopping.html
The entries you see in the logs are almost certainly there because your provider used SIGTERM for that purpose. If it's truly crashing, not even serving static content, then that sounds like some sort of a thread/connection exhaustion issue. Perhaps a DoS that holds connections open?
Should definitely be something for your provider to investigate.
Lots of great answers here but they might be superseded by this CMake support in Visual Studio (Oct 5 2016)
I did it a different way to what I was wanting to do...gave me the result I needed. I chose not to submit the form, rather just get the value of the text field and use it in the javascript and then reset the text field. Sorry if I bothered anyone with this question.
Basically just did this:
var search = document.getElementById('search').value;
document.getElementById('search').value = "";
Had the same bug. Actually worked in case the traffic was sent using some proxy (fiddler in my case). Updated .NET framework from 4.5.2 to >=4.6 and now everything works fine. The actual request was:
new WebClient().DownloadData("URL");
The exception was:
SocketException: An existing connection was forcibly closed by the remote host
The answer is no. Keep in mind that in both cases, mdDate.Kind = DateTimeKind.Unspecified
.
Therefore it may be better to do the following:
DateTime myDate = new DateTime(1, 1, 1, 0, 0, 0, DateTimeKind.Utc);
The myDate.Kind
property is readonly, so it cannot be changed after the constructor is called.
I think you missed a equal sign at:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);
Change to:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null);
The attributes
property contains them all:
$(this).each(function() {
$.each(this.attributes, function() {
// this.attributes is not a plain object, but an array
// of attribute nodes, which contain both the name and value
if(this.specified) {
console.log(this.name, this.value);
}
});
});
What you can also do is extending .attr
so that you can call it like .attr()
to get a plain object of all attributes:
(function(old) {
$.fn.attr = function() {
if(arguments.length === 0) {
if(this.length === 0) {
return null;
}
var obj = {};
$.each(this[0].attributes, function() {
if(this.specified) {
obj[this.name] = this.value;
}
});
return obj;
}
return old.apply(this, arguments);
};
})($.fn.attr);
Usage:
var $div = $("<div data-a='1' id='b'>");
$div.attr(); // { "data-a": "1", "id": "b" }
So, after a while of searching, and finding out that strtol is quite slow, I've coded my own function. It only works for uppercase on letters, but adding lowercase functionality ain't a problem.
int hexToInt(PCHAR _hex, int offset = 0, int size = 6)
{
int _result = 0;
DWORD _resultPtr = reinterpret_cast<DWORD>(&_result);
for(int i=0;i<size;i+=2)
{
int _multiplierFirstValue = 0, _addonSecondValue = 0;
char _firstChar = _hex[offset + i];
if(_firstChar >= 0x30 && _firstChar <= 0x39)
_multiplierFirstValue = _firstChar - 0x30;
else if(_firstChar >= 0x41 && _firstChar <= 0x46)
_multiplierFirstValue = 10 + (_firstChar - 0x41);
char _secndChar = _hex[offset + i + 1];
if(_secndChar >= 0x30 && _secndChar <= 0x39)
_addonSecondValue = _secndChar - 0x30;
else if(_secndChar >= 0x41 && _secndChar <= 0x46)
_addonSecondValue = 10 + (_secndChar - 0x41);
*(BYTE *)(_resultPtr + (size / 2) - (i / 2) - 1) = (BYTE)(_multiplierFirstValue * 16 + _addonSecondValue);
}
return _result;
}
Usage:
char *someHex = "#CCFF00FF";
int hexDevalue = hexToInt(someHex, 1, 8);
1 because the hex we want to convert starts at offset 1, and 8 because it's the hex length.

strtol ~ 0.4400s
hexToInt ~ 0.1100s

Then go to php folder directory, Suppose your php folder is in xampp folder on your c drive. Your command would then be:
cd c:\xampp\php
After that, check your version:
php -v
This should give the following output:

Simplest way,
Controller:
[HttpGet("empId={empId}&startDate={startDate}&endDate={endDate}")]
public IEnumerable<Validate> Get(int empId, string startDate, string endDate){}
Postman Request:
{router}/empId=1&startDate=2020-20-20&endDate=2020-20-20
Learning point: Request exact pattern will be accepted by the Controller.
You could escape the % in %20 like so:
print "Hello%%20World%s" %"!"
or you could try using the string formatting routines instead, like:
print "Hello%20World{0}".format("!")
If you are using IIS server by chance. you can set below headers in the HTTP request headers option.
Access-Control-Allow-Origin:*
Access-Control-Allow-Methods: 'HEAD, GET, POST, PUT, PATCH, DELETE'
Access-Control-Allow-Headers: 'Origin, Content-Type, X-Auth-Token';
with this all post, get etc., will work fine.
Lets say, you're running test for creating todo. You can always run that specific todo spec code using the file crete_spec.rb file as below.

Editing rspec spec/features/todos/edit_spec.rb
Deleting rspec spec/features/todos/destroy_spec.rb
If you want to run all the specs in one single short.

If you want to be able to have a SELECT without problems of the parent id having to be lower than child id, a function could be used. It supports also multiple children (as a tree should do) and the tree can have multiple heads. It also ensure to break if a loop exists in the data.
I wanted to use dynamic SQL to be able to pass the table/columns names, but functions in MySQL don't support this.

You are probably using Windows, so new line is CR + LF
(carriage return + line feed). So solution would be:

<?xml-stylesheet type="text/xsl" href="dummy.xsl"?>
<item>
<summary>Tootsie roll tiramisu macaroon wafer carrot cake. Danish topping sugar plum tart bonbon caramels cake.

For Linux there is only LF
and for Mac OS only CR
.
In question there showed Linux way.
Prior to standardization there was ioctl(
...FIONBIO
...)
and fcntl(
...O_NDELAY
...)
, but these behaved inconsistently between systems, and even within the same system. For example, it was common for FIONBIO
to work on sockets and O_NDELAY
to work on ttys, with a lot of inconsistency for things like pipes, fifos, and devices. And if you didn't know what kind of file descriptor you had, you'd have to set both to be sure. But in addition, a non-blocking read with no data available was also indicated inconsistently; depending on the OS and the type of file descriptor the read may return 0, or -1 with errno EAGAIN, or -1 with errno EWOULDBLOCK. Even today, setting FIONBIO
or O_NDELAY
on Solaris causes a read with no data to return 0 on a tty or pipe, or -1 with errno EAGAIN on a socket. However 0 is ambiguous since it is also returned for EOF.
POSIX addressed this with the introduction of O_NONBLOCK
, which has standardized behavior across different systems and file descriptor types. Because existing systems usually want to avoid any changes to behavior which might break backward compatibility, POSIX defined a new flag rather than mandating specific behavior for one of the others. Some systems like Linux treat all 3 the same, and also define EAGAIN and EWOULDBLOCK to the same value, but systems wishing to maintain some other legacy behavior for backward compatibility can do so when the older mechanisms are used.
New programs should use fcntl(
...O_NONBLOCK
...)
, as standardized by POSIX.
Adding to this question if you ever have more than one columns to remap in a data dataframe:
def remap(data,dict_labels):
"""
This function take in a dictionnary of labels : dict_labels
and replace the values (previously labelencode) into the string.
ex: dict_labels = {{'col1':{1:'A',2:'B'}}
"""
for field,values in dict_labels.items():
print("I am remapping %s"%field)
data.replace({field:values},inplace=True)
print("DONE")
return data
Hope it can be useful to someone.
Cheers
Here's another one:
people = []
1.times do
info = gets.chomp
unless info.empty?
people += [Person.new(info)]
redo
end
end
Yes - absolutely. Looking up a class via reflection is, by magnitude, more expensive.
Quoting Java's documentation on reflection:
Because reflection involves types that are dynamically resolved, certain Java virtual machine optimizations can not be performed. Consequently, reflective operations have slower performance than their non-reflective counterparts, and should be avoided in sections of code which are called frequently in performance-sensitive applications.
Here's a simple test I hacked up in 5 minutes on my machine, running Sun JRE 6u10:
public class Main {
public static void main(String[] args) throws Exception
{
doRegular();
doReflection();
}
public static void doRegular() throws Exception
{
long start = System.currentTimeMillis();
for (int i=0; i<1000000; i++)
{
A a = new A();
a.doSomeThing();
}
System.out.println(System.currentTimeMillis() - start);
}
public static void doReflection() throws Exception
{
long start = System.currentTimeMillis();
for (int i=0; i<1000000; i++)
{
A a = (A) Class.forName("misc.A").newInstance();
a.doSomeThing();
}
System.out.println(System.currentTimeMillis() - start);
}
}
With these results:
35 // no reflection
465 // using reflection
Bear in mind the lookup and the instantiation are done together, and in some cases the lookup can be refactored away, but this is just a basic example.
Even if you just instantiate, you still get a performance hit:
30 // no reflection
47 // reflection using one lookup, only instantiating
Again, YMMV.

There are two reasons you might get this message:
%FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i
. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.var val = $("#checkboxId").is(":checked");
First convert the value in a string to iterate it, Them each value can be convert to a Integer value = 12345
l = [ int(item) for item in str(value) ]
Your code gets the DirectorySecurity
for a given directory, and handles an exception (due to your not having access to the security info) correctly. However, in your sample you don't actually interrogate the returned object to see what access is allowed - and I think you need to add this in.
In Python one would usually use lists for this purpose. Lists can be nested arbitrarily, thus allowing the creation of a 2D array. Not every sublist needs to be the same size, so that solves your other problem. Have a look at the examples I linked to.

All you will have to do is
class BatchCollection(dict):
def __init__(self, *args, **kwargs):
dict.__init__(*args, **kwargs)
OR
class BatchCollection(dict):
def __init__(self, inpt={}):
super(BatchCollection, self).__init__(inpt)
A sample usage for my personal use
### EXAMPLE
class BatchCollection(dict):
def __init__(self, inpt={}):
dict.__init__(*args, **kwargs)
def __setitem__(self, key, item):
if (isinstance(key, tuple) and len(key) == 2
and isinstance(item, collections.Iterable)):
# self.__dict__[key] = item
super(BatchCollection, self).__setitem__(key, item)
else:
raise Exception(
"Valid key should be a tuple (database_name, table_name) "
"and value should be iterable")
Note: tested only in python3
You can Simply Change Background Color of a View:
var body : some View{
VStack{
Color.blue.edgesIgnoringSafeArea(.all)
}
}
and You can also use ZStack :
var body : some View{
ZStack{
Color.blue.edgesIgnoringSafeArea(.all)
}
}
As far as I can see from the implementation at https://github.com/angular/angular/blob/master/packages/common/http/src/params.ts
You must provide values separately - You are not able to avoid your loop.
There is also a constructor which takes a string as a parameter, but it is in form param=value¶m2=value2
so there is no deal for You (in both cases you will finish with looping your object).
You can always report an issue/feature request to angular, what I strongly advise: https://github.com/angular/angular/issues
PS: Remember about difference between set
and append
methods ;)
Try:
jQuery("#availability option:selected").val();
Or to get the text of the option, use text()
:
jQuery("#availability option:selected").text();
More Info:
Check out enaml-native which takes the react-native concept and applies it to python.
It lets users build apps with native Android widgets and provides APIs to use android and java libraries from python.
It also integrates with android-studio and shares a few of react's nice dev features like code reloading and remote debugging.
Call SYS_CONTEXT
to get the current schema. From Ask Tom "How to get current schema:
select sys_context( 'userenv', 'current_schema' ) from dual;
From JQuery Documentation
The jqXHR objects returned by $.ajax()
as of jQuery 1.5 implement the Promise interface, giving them all the properties, methods, and behavior of a Promise (see Deferred object for more information). These methods take one or more function arguments that are called when the $.ajax()
request terminates. This allows you to assign multiple callbacks on a single request, and even to assign callbacks after the request may have completed. (If the request is already complete, the callback is fired immediately.) Available Promise methods of the jqXHR object include:
jqXHR.done(function( data, textStatus, jqXHR ) {});
An alternative construct to the success callback option, refer to deferred.done()
for implementation details.
jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {});
An alternative construct to the error callback option, the .fail()
method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.
jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { });
(added in jQuery 1.6)
An alternative construct to the complete callback option, the .always()
method replaces the deprecated .complete()
method.
In response to a successful request, the function's arguments are the same as those of .done()
: data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail()
: the jqXHR object, textStatus, and errorThrown. Refer to deferred.always()
for implementation details.
jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {});
Incorporates the functionality of the .done()
and .fail()
methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then()
for implementation details.
Deprecation Notice: The
jqXHR.success()
,jqXHR.error()
, andjqXHR.complete()
callbacks are removed as of jQuery 3.0. You can usejqXHR.done()
,jqXHR.fail()
, andjqXHR.always()
instead.
Use substring
http://php.net/manual/en/function.substr.php
$foo = substr("abcde",0, 3) . "...";
Please show us more parts of the script and tell us what commands you had to individually execute and want to simply.
Meanwhile you have to use double quotes not single quote to expand variables:
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
Semicolons at the end of a single command are also unnecessary.
So far:
#!/bin/sh
echo "Perform Operation in su mode"
export ARCH=arm
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...
For su
you can run it with:
su -c 'sh /path/to/script.sh'
Note: The OP was not explicitly asking for steps on how to create export variables in an interactive shell using a shell script. He only asked his script to be assessed at most. He didn't mention details on how his script would be used. It could have been by using .
or source
from the interactive shell. It could have been a standalone scipt, or it could have been source
'd from another script. Environment variables are not specific to interactive shells. This answer solved his problem.
Python 3.6 gives us f-strings, which are a delight:
var1 = "foo"
var2 = "bar"
var3 = f"{var1}{var2}"
print(var3) # prints foobar
You can do most anything inside the curly braces
print(f"1 + 1 == {1 + 1}") # prints 1 + 1 == 2
Use @RequestParam
@RequestMapping(value="user", method = RequestMethod.GET)
public @ResponseBody Item getItem(@RequestParam("data") String itemid){
Item i = itemDao.findOne(itemid);
String itemName = i.getItemName();
String price = i.getPrice();
return i;
}
You can handle the keydown event of your TextBox
control.
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyCode==Keys.Enter)
buttonSearch_Click(sender,e);
}
It works even when the button Visible
property is set to false
In Java x ^ y
is an XOR
operation.
I know this is an old question, but I've just had the same frustrating issue for a couple of hours and wanted to share my solution. In my case the option "Managements Tools" wasn't available in the installation menu either. It wasn't just greyed out as disabled or already installed, but instead just missing, it wasn't anywhere on the menu.
So what finally worked for me was to use the Web Platform Installer 4.0, and check this for installation: Products > Database > "Sql Server 2008 R2 Management Objects". Once this is done, you can relaunch the installation and "Management Tools" will appear like previous answers stated.
Note there could also be a "Sql Server 2012 Shared Management Objects", but I think this is for different purposes.
Hope this saves someone the couple of hours I wasted into this.
The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.
From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/
the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.
var wordOccurrences = words
.GroupBy(w => w)
.Select(intermediate => new
{
Word = intermediate.Key,
Frequency = intermediate.Sum(w => 1)
})
.Where(w => w.Frequency > 10)
.OrderBy(w => w.Frequency);
For the distributed portion, you could check out DryadLINQ: http://research.microsoft.com/en-us/projects/dryadlinq/default.aspx
Using dplyr you can:
df <- df %>% dplyr:: select(grep("ABC", names(df)), grep("XYZ", names(df)))
As per MSDN
Create MD5:
public static string CreateMD5(string input)
{
// Use input string to calculate MD5 hash
using (System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create())
{
byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
byte[] hashBytes = md5.ComputeHash(inputBytes);
// Convert the byte array to hexadecimal string
StringBuilder sb = new StringBuilder();
for (int i = 0; i < hashBytes.Length; i++)
{
sb.Append(hashBytes[i].ToString("X2"));
}
return sb.ToString();
}
}
Simply execute
CKEDITOR.instances[elementId].getData();
with element id = id
of element assigned the editor.
You have to loop through the array and printf()
each element:
for(int i=0;i<10;++i) {
printf("%.2f ", foo[i]);
}
printf("\n");
I was using the $('div').attr('style', '');
technique and it wasn't working in IE8.
I outputted the style attribute using alert()
and it was not stripping out inline styles.
.removeAttr
ended up doing the trick in IE8.
You're comparing strings. JavaScript compares the ASCII code for each character of the string.
To see why you get false, look at the charCodes:
"1300".charCodeAt(0);
49
"999".charCodeAt(0);
57
The comparison is false because, when comparing the strings, the character codes for 1 is not greater than that of 9.
The fix is to treat the strings as numbers. You can use a number of methods:
parseInt(string, radix)
parseInt("1300", 10);
> 1300 - notice the lack of quotes
+"1300"
> 1300
Number("1300")
> 1300
A void*
pointer is used when you want to indicate a pointer to a hunk of memory without specifying the type. C's malloc
returns such a pointer, expecting you to cast it to a particular type immediately. It really isn't useful until you cast it to another pointer type. You're expected to know which type to cast it to, the compiler has no reflection capability to know what the underlying type should be.
First convert this structure to a "dictionary" object:
dict = {}
json.forEach(function(x) {
dict[x.code] = x.name
})
and then simply
countryName = dict[countryCode]
For a list of countries this doesn't matter much, but for larger lists this method guarantees the instant lookup, while the naive searching will depend on the list size.
You will not only have to use an asp.net page but
If using the Entity Framework or LinqToSql (if using partial classes) move the data into a separate project, the report designer cannot see the classes.
Move the reports to another project/dll, VS10 has bugs were asp.net projects cannot see object datasources in web apps. Then stream the reports from the dll into your mvc projects aspx page.
This applies for mvc and webform projects. Using sql reports in the local mode is not a pleasent development experience. Also watch your webserver memory if exporting large reports. The reportviewer/export is very poorly designed.
You do not need to create data frame from vector of strings, if you want to replace some characters in it. Regular expressions is good choice for it as it has been already mentioned by @Andrie and @Dirk Eddelbuettel.
Pay attention, if you want to replace special characters, like dots, you should employ full regular expression syntax, as shown in example below:
ctr_names <- c("Czech.Republic","New.Zealand","Great.Britain")
gsub("[.]", " ", ctr_names)
this will produce
[1] "Czech Republic" "New Zealand" "Great Britain"
If you really want to speed up your code, what about that?
for( var i=0,j=null; j=array[i++]; foo(j) );
it's kinda of having the while logic within the for statement and it's less redundant. Also firefox has Array.forEach and Array.filter
You could execute the .sql
file as a script in the SQL Developer worksheet. Either use the Run Script icon, or simply press F5.
For example,
@path\script.sql;
Remember, you need to put @
as shown above.
But, if you have exported the database using database export utility of SQL Developer, then you should use the Import utility. Follow the steps mentioned here Importing and Exporting using the Oracle SQL Developer 3.0
Just provide dot (.) at the end of command including one space.
example:
command: docker build -t "blink:v1" .
Here you can see "blink:v1" then a space then dot(.)
Thats it.
Have you tried the json module? JSON format is very similar to python dictionary. And it's human readable/writable:
>>> import json
>>> d = {"one":1, "two":2}
>>> json.dump(d, open("text.txt",'w'))
This code dumps to a text file
$ cat text.txt
{"two": 2, "one": 1}
Also you can load from a JSON file:
>>> d2 = json.load(open("text.txt"))
>>> print d2
{u'two': 2, u'one': 1}
There is a simplier way, create a form and post it, this runs the risk of resetting the page if the return mime type is something that a browser would open, but for csv and such it's perfect
Example requires underscore and jquery
var postData = {
filename:filename,
filecontent:filecontent
};
var fakeFormHtmlFragment = "<form style='display: none;' method='POST' action='"+SAVEAS_PHP_MODE_URL+"'>";
_.each(postData, function(postValue, postKey){
var escapedKey = postKey.replace("\\", "\\\\").replace("'", "\'");
var escapedValue = postValue.replace("\\", "\\\\").replace("'", "\'");
fakeFormHtmlFragment += "<input type='hidden' name='"+escapedKey+"' value='"+escapedValue+"'>";
});
fakeFormHtmlFragment += "</form>";
$fakeFormDom = $(fakeFormHtmlFragment);
$("body").append($fakeFormDom);
$fakeFormDom.submit();
For things like html, text and such, make sure the mimetype is some thing like application/octet-stream
php code
<?php
/**
* get HTTP POST variable which is a string ?foo=bar
* @param string $param
* @param bool $required
* @return string
*/
function getHTTPPostString ($param, $required = false) {
if(!isset($_POST[$param])) {
if($required) {
echo "required POST param '$param' missing";
exit 1;
} else {
return "";
}
}
return trim($_POST[$param]);
}
$filename = getHTTPPostString("filename", true);
$filecontent = getHTTPPostString("filecontent", true);
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename\"");
echo $filecontent;

Please have a look at the Spring Data JPA - Reference Documentation, section 5.3. Query Methods, especially at section 5.3.2. Query Creation, in "Table 3. Supported keywords inside method names" (links as of 2019-05-03).
I think it has exactly what you need and same query as you stated should work...
Same thing you'd expect from normal modulo .. e.g. 7 % 4 = 3
, 7.3 % 4.0 = 3.3
Beware of floating point accuracy issues.
You all seem to love complication. Just click on column(to select entire column), press and hold CTRL and click on cells that you want to exclude(C1 to C5 in you case). Now you have selected entire column C (right to the end of sheet) without starting cells. All you have to do now is to rightclick and "Define Name" for your selection(ex. asdf ). In formula you use SUM(asdf). And now you're done. Good luck
Allways find the easyest way ;)

this solved my issue.hope it helps you too. Best Regards.
The simplest CMakeLists.txt I distilled from answers in this thread and some trial and error is:
project(test CXX C)
cmake_minimum_required(VERSION 2.6.2)
#include folder contains current project's header filed
include_directories("include")
#test folder contains test files
set (PROJECT_SOURCE_DIR test)
add_executable(hex2base64 ${PROJECT_SOURCE_DIR}/hex2base64.cpp)
# Link test executable against gtest nothing else required
target_link_libraries(hex2base64 gtest pthread)
Gtest should already be installed on your system.
The InnoDB engine does not store deleted data. As you insert and delete rows, unused space is left allocated within the InnoDB storage files. Over time, the overall space will not decrease, but over time the 'deleted and freed' space will be automatically reused by the DB server.
You can further tune and manage the space used by the engine through an manual re-org of the tables. To do this, dump the data in the affected tables using mysqldump, drop the tables, restart the mysql service, and then recreate the tables from the dump files.
You could move the common parts to another configuration file and include
from both server contexts. This should work:
server {
listen 80;
server_name server1.example;
...
include /etc/nginx/include.d/your-common-stuff.conf;
}
server {
listen 80;
server_name another-one.example;
...
include /etc/nginx/include.d/your-common-stuff.conf;
}
Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled
(normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org
's configuration file is /etc/nginx/sites-enabled
and it looks like this:
server {
listen 80 default_server;
listen [2a01:4f8:120:3105::101:1]:80 default_server;
include /etc/nginx/include.d/all-common;
include /etc/nginx/include.d/bunkus.org-common;
include /etc/nginx/include.d/bunkus.org-80;
}
server {
listen 443 default_server;
listen [2a01:4f8:120:3105::101:1]:443 default_server;
include /etc/nginx/include.d/all-common;
include /etc/nginx/include.d/ssl-common;
include /etc/nginx/include.d/bunkus.org-common;

You can use Eclipse DDMS perspective to see connected devices and browse through files, you can also pull and push files to the device. You can also do a bunch of stuff using DDMS, this link explains a little bit more of DDMS uses.
EDIT:
If you just want to copy a database you can locate the database on eclipse DDMS file explorer, select it and then pull the database from the device to your computer.
What I do is to recognize everything, and when I have the text, I take out all the characters except numbers
//This replaces all except numbers from 0 to 9
recognizedText = recognizedText.replaceAll("[^0-9]+", " ");
This works pretty well for me.
You might be looking for a List
? Either LinkedList
or ArrayList
are good classes to take a look at. You can then call toArray()
to get the list as an array.
You can convert a number to a string with n decimal places using the SPRINTF command:
>> x = 1.23; >> sprintf('%0.6f', x) ans = 1.230000 >> x = 1.23456789; >> sprintf('%0.6f', x) ans = 1.234568

409 Conflict
could be an acceptable solution.
According to: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.
The doc continues with an example:
Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.
In my case, I would like to PUT a string, that must be unique, to a database via an API. Before adding it to the database, I am checking that it is not already in the database.
If it is, I will return "Error: The string is already in the database", 409
.
I believe this is what the OP wanted: an error code suitable for when the data does not pass the server's criteria.
Wget currently only supports x-www-form-urlencoded data. --post-file
is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example
.
--post-data
and --post-file
work the same way: the only difference is that --post-data
allows you to specify the data in the command line, while --post-file
allows you to specify the path of the file that contain the data to send.
Here's the documentation:
--post-data=string
--post-file=file
Use POST as the method for all HTTP requests and send the specified data
in the request body. --post-data sends string as data, whereas
--post-file sends the contents of file. Other than that, they work in
exactly the same way. In particular, they both expect content of the
form "key1=value1&key2=value2", with percent-encoding for special
characters; the only difference is that one expects its content as a
command-line parameter and the other accepts its content from a file. In
particular, --post-file is not for transmitting files as form
attachments: those must appear as "key=value" data (with appropriate
percent-coding) just like everything else. Wget does not currently
support "multipart/form-data" for transmitting POST data; only
"application/x-www-form-urlencoded". Only one of --post-data and
--post-file should be specified.
Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.
Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN
.
wget --post-data 'user=foo&password=bar' http://example.com/auth.php
Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.
We are using an inhouse developed solution that is basicly a procedure with arguments of what you want included in the comparision (SP's, Full SP code, table structure, defaults, indices, triggers.. etc)
Depending on your needs and budget, it might be a good way to go for you as well.
It is quite easily developed as well, then we just redirect output of procedure to textfiles and do text comparisions between the files.
One good thing about it is that its possible to save the output in source control.
/B
there is another way, if you are using a container like Tomcat :
String textPath = "http://localhost:8080/NameOfWebapp/resources/images/file.txt";
how about using limit 0,1
for mysql optimisation
and about your code:
$DBH = new PDO( "connection string goes here" );
$STH - $DBH -> prepare( "select figure from table1" );
$STH -> execute();
$result = $STH ->fetch(PDO::FETCH_ASSOC)
echo $result["figure"];
$DBH = null;
Like you have mentioned, The default -Xmxsize
(Maximum HeapSize) depends on your system configuration.
Java8 client
takes Larger of 1/64th of your physical memory for your Xmssize
(Minimum HeapSize) and Smaller of 1/4th of your physical memory for your -Xmxsize
(Maximum HeapSize).
Which means if you have a physical memory of 8GB RAM, you will have Xmssize
as Larger of 8*(1/6) and Smaller of -Xmxsize
as 8*(1/4).
You can Check your default HeapSize with
In Windows:
java -XX:+PrintFlagsFinal -version | findstr /i "HeapSize PermSize ThreadStackSize"
In Linux:
java -XX:+PrintFlagsFinal -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'
These default values can also be overrided to your desired amount.
Just as a side note, <button>
will implicitly submit, which can cause problems if you want to use a button in a form without it submitting. Thus, another reason to use <input type="button">
(or <button type="button">
)
Edit - more details
Without a type, button
implicitly receives type of submit
. It does not matter how many submit buttons or inputs there are in the form, any one of them which is explicitly or implicitly typed as submit, when clicked, will submit the form.
There are 3 supported types for a button
submit || "submits the form when clicked (default)"
reset || "resets the fields in the form when clicked"
button || "clickable, but without any event handler until one is assigned"
In a recent application that I made, I used the inverted colors. With the r,g and b values in hand, just calculate (in this example, the color range varies from 0 to 255) :
r = 127-(r-127) and so on.
If you want to access the data in instance B from the instance A. Then this is the query, you can edit your respective credential.
CREATE DATABASE LINK dblink_passport

After executing this query access table
SELECT * FROM tablename@dblink_passport;

First add Dimension component:
import { AppRegistry, Text, View,Dimensions } from 'react-native';
Second define Variables:
var height = Dimensions.get('window').height;
var width = Dimensions.get('window').width;
Third put it in your stylesheet:
textOutputView: {
flexDirection:'row',
paddingTop:20,
borderWidth:1,
borderColor:'red',
height:height*0.25,
backgroundColor:'darkgrey',
justifyContent:'flex-end'
}
Actually in this example I wanted to make responsive view and wanted to view only 0.25 of the screen view so I multiplied it with 0.25, if you wanted 100% of the screen don't multiply it with any thing like this:
textOutputView: {
flexDirection:'row',
paddingTop:20,
borderWidth:1,
borderColor:'red',
height:height,
backgroundColor:'darkgrey',
justifyContent:'flex-end'
}
Yes, Ctrl + Shift + A is the most useful one. It's a meta shortcut
This: "\0"
is a string, not a character. A character uses single quotes, like '\0'

Since the question was first asked, there has been a change to that answer from a flat out "no" to a "kind of"
http://github.com/facebook/hiphop-php/wiki
Hip Hop for PHP was a compiler that took PHP code and turned it into highly optimized C++ Apparently, some functions are not supported (for example 'explode')
I found this question while looking for more information on how to implement HipHop and thought I'd speak up :)
Since 2013 Facebook no longer use it, however, and it has been discontinued in favour of HHVM, which is not a compiler: https://en.wikipedia.org/wiki/HipHop_for_PHP
Complementing the answer from @Nishant,the best way to return the activity result is:
Intent returnIntent = getIntent();
returnIntent.putExtra("result",result);
setResult(RESULT_OK,returnIntent);
finish();
I was having problem with
new Intent();
Then I found out that the correct way is using
getIntent();
to get the current intent

TomcatURLStreamHandlerFactory.register();
This will register handlers for "war" and "classpath" protocols.

Iterating over two dimensions means you'll need to check over two dimensions.
assuming you're starting with:
var myArray = [
[1,1,1,1,1],
[1,1,1,1,1],
[1,1,1,1,1]
]; //don't forget your semi-colons
You want to expand this two-dimensional array to become:
var myArray = [
[1,1,1,1,1,0,0],
[1,1,1,1,1,0,0],
[1,1,1,1,1,0,0],
[0,0,0,0,0,0,0],
[0,0,0,0,0,0,0],
[0,0,0,0,0,0,0],
];
Which means you need to understand what the difference is.
Start with the outer array:
var myArray = [
[...],
[...],
[...]
];
If you want to make this array longer, you need to check that it's the correct length, and add more inner arrays to make up the difference:
var i,
rows,
myArray;
rows = 8;
myArray = [...]; //see first example above
for (i = 0; i < rows; i += 1) {
//check if the index exists in the outer array
if (!(i in myArray)) {
//if it doesn't exist, we need another array to fill
myArray.push([]);
}
}
The next step requires iterating over every column in every array, we'll build on the original code:
var i,
j,
row,
rows,
cols,
myArray;
rows = 8;
cols = 7; //adding columns in this time
myArray = [...]; //see first example above
for (i = 0; i < rows; i += 1) {
//check if the index exists in the outer array (row)
if (!(i in myArray)) {
//if it doesn't exist, we need another array to fill
myArray[i] = [];
}
row = myArray[i];
for (j = 0; j < cols; j += 1) {
//check if the index exists in the inner array (column)
if (!(i in row)) {
//if it doesn't exist, we need to fill it with `0`
row[j] = 0;
}
}
}
I compared how the following three options perform:
import random, datetime
myDict = {}
for i in range( 10000000 ):
myDict[ i ] = random.randint( 0, 10000000 )
# OPTION 1
start = datetime.datetime.now()
sorted = []
for i in myDict:
sorted.append( ( i, myDict[ i ] ) )
sorted.sort( key = lambda x: x[1] )
print( sorted[0][0] )
end = datetime.datetime.now()
print( end - start )
# OPTION 2
start = datetime.datetime.now()
myDict_values = list( myDict.values() )
myDict_keys = list( myDict.keys() )
min_value = min( myDict_values )
print( myDict_keys[ myDict_values.index( min_value ) ] )
end = datetime.datetime.now()
print( end - start )
# OPTION 3
start = datetime.datetime.now()
print( min( myDict, key=myDict.get ) )
end = datetime.datetime.now()
print( end - start )
Sample output:
#option 1
236230
0:00:14.136808
#option 2
236230
0:00:00.458026
#option 3

Here's my version of @Piotr Czapla's method:
def md5sum(filename):
md5 = hashlib.md5()

for chunk in iter(lambda: f.read(128 * md5.block_size), b''):
md5.update(chunk)
return md5.hexdigest()
I have found that in all browsers I test, the fastest way is to actually fillRect with white, or whataever color you would like. I have a very large monitor and in full screen mode the clearRect is agonizingly slow, but the fillRect is reasonable.
context.fillStyle = "#ffffff";
context.fillRect(0,0,canvas.width, canvas.height);
The drawback is that the canvas is no longer transparent.

The NVARCHAR2 datatype was introduced by Oracle for databases that want to use Unicode for some columns while keeping another character set for the rest of the database (which uses VARCHAR2). The NVARCHAR2 is a Unicode-only datatype.
One reason you may want to use NVARCHAR2 might be that your DB uses a non-Unicode character set and you still want to be able to store Unicode data for some columns without changing the primary character set. Another reason might be that you want to use two Unicode character set (AL32UTF8 for data that comes mostly from western Europe, AL16UTF16 for data that comes mostly from Asia for example) because different character sets won't store the same data equally efficiently.
Both columns in your example (Unicode VARCHAR2(10 CHAR)
and NVARCHAR2(10)
) would be able to store the same data, however the byte storage will be different. Some strings may be stored more efficiently in one or the other.
Note also that some features won't work with NVARCHAR2, see this SO question:
For tables you must loop that:
for tbl in `psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" YOUR_DB` ; do psql -U postgres -c "alter table \"$tbl\" owner to NEW_USER" YOUR_DB ; done
Are you sure it needs to be an array? You may be able to use respond_to?(method)
so your code would work for similar things that aren't necessarily arrays (maybe some other enumberable thing). If you do actually need an array
, then the post describing the Array#kind\_of?
method is best.
['hello'].respond_to?('each')
no.
BufferedReader.close()
closes the stream according to javadoc for BufferedReader and InputStreamReader
as well as
FileReader.close()
does.
You can use that:
let s: string = "true";
let b: boolean = Boolean(s);
to do it we have to know the three components
firing the Event
responding to the Event
the Event itself
a. Event
b .EventArgs
c. EventArgs enumeration
now lets create Event that fired when a function is called
but I my order of solving this problem like this: I'm using the class before I create it
the place responsible for responding to the Event
NetLog.OnMessageFired += delegate(object o, MessageEventArgs args)
{
// when the Event Happened I want to Update the UI
// this is WPF Window (WPF Project)
this.Dispatcher.Invoke(() =>
{
LabelFileName.Content = args.ItemUri;
LabelOperation.Content = args.Operation;
LabelStatus.Content = args.Status;
});
};
NetLog is a static class I will Explain it later
the next step is
the place responsible for firing the Event
//this is the sender object, MessageEventArgs Is a class I want to create it and Operation and Status are Event enums
NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Started));
downloadFile = service.DownloadFile(item.Uri);
NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Finished));
the third step
I warped The Event within a class called NetLog
public sealed class NetLog
{
public delegate void MessageEventHandler(object sender, MessageEventArgs args);
public static event MessageEventHandler OnMessageFired;
public static void FireMessage(Object obj,MessageEventArgs eventArgs)
{
if (OnMessageFired != null)
{
OnMessageFired(obj, eventArgs);
}
}
}
public class MessageEventArgs : EventArgs
{
public string ItemUri { get; private set; }
public Operation Operation { get; private set; }
public Status Status { get; private set; }
public MessageEventArgs(string itemUri, Operation operation, Status status)
{
ItemUri = itemUri;
Operation = operation;
Status = status;
}
}
public enum Operation
{
Upload,Download
}
public enum Status
{
Started,Finished
}
this class now contain the Event
, EventArgs
and EventArgs Enums
and the function
responsible for firing the event
sorry for this long answer
LinkedHashMap
is precisely what you're looking for.
It is exactly like HashMap
, except that when you iterate over it, it presents the items in the insertion order.
A portable way of doing this is using a custom function (to handle browser differences) like this one.
Then setup a handler for the onload
at the end of your <body>
tag, as jessegavin wrote:
window.onload = function() {
document.getElementById("myinputbox").focus();
}
class Materials:
Shaded, Shiny, Transparent, Matte = range(4)
>>> print Materials.Matte

The answer from @Emiliano is excellent. You can also pass named parameters like so:
powershell.exe -Command 'G:\Karan\PowerShell_Scripts\START_DEV.ps1' -NamedParam1 "SomeDataA" -NamedParam2 "SomeData2"
Note the parameters are outside the command call, and you'll use:
[parameter(Mandatory=$false)]
[string]$NamedParam1,
[parameter(Mandatory=$false)]
[string]$NamedParam2
Select Case parameter
Case "userID"
' does something here.
Case "packageID"
' does something here.
Case "mvrType"
If otherFactor Then
' does something here.
End If
Case Else
' does some processing...
Exit Select
End Select
Is there a reason for the goto? If it doesn't meet the if criterion, it will simply not perform the function and go to the next case.
When you install anaconda on windows now, it doesn't automatically add Python or Conda.
If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt
Next, you can add Python and Conda to your path by using the setx command in your command prompt.
Next close that command prompt and open a new one. Congrats you can now use conda and python

In my case, if I remove the the contentType
, I get the Internal Server Error.
This is what I got working after multiple attempts:
var request = $.ajax({
type: 'POST',
url: '/ControllerName/ActionName' ,
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({ projId: 1, userId:1 }), //hard-coded value used for simplicity
dataType: 'json'
});
request.done(function(msg) {
alert(msg);
});
request.fail(function (jqXHR, textStatus, errorThrown) {
alert("Request failed: " + jqXHR.responseStart +"-" + textStatus + "-" + errorThrown);
});
And this is the controller code:
public JsonResult ActionName(int projId, int userId)
{
var obj = new ClassName();
var result = obj.MethodName(projId, userId); // variable used for readability
return Json(result, JsonRequestBehavior.AllowGet);
}
Please note, the case of ASP.NET is little different, we have to apply JSON.stringify()
to the data as mentioned in the update of this answer.
Character only takes one value dude! like: char y = 'h'; and maybe you typed like char y = 'hello'; or smthg. good luck. for the question asked above the answer is pretty simple u have to use DOUBLE QUOTES to give a string value. easy enough;)
DDL is Data Definition Language : Specification notation for defining the database schema. It works on Schema level.
DDL commands are:
create,drop,alter,rename
For example:
create table account (
account_number char(10),
balance integer);
DML is Data Manipulation Language .It is used for accessing and manipulating the data.
DML commands are:
select,insert,delete,update,call
For example :
update account set balance = 1000 where account_number = 01;
I've tried a few times to get the ajax form submit working nicely, but always met with either complete failure or too many compromises. Here's an example of page that uses the jQuery Form plug-in inside of a MVC page to update a list of projects (using a partially rendered control) as the user types in an input box:
<div class="searchBar">
<form action="<%= Url.Action ("SearchByName") %>" method="get" class="searchSubmitForm">
<label for="projectName">Search:</label>
<%= Html.TextBox ("projectName") %>
<input class="submit" type="submit" value="Search" />
</form>
</div>
<div id="projectList">
<% Html.RenderPartial ("ProjectList", Model); %>
</div>
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery("#projectName").keyup(function() {
jQuery(".searchSubmitForm").submit();
});
jQuery(".searchSubmitForm").submit(function() {
var options = {
target : '#projectList'
}
jQuery(this).ajaxSubmit(options);
return false;
});
// We remove the submit button here - good Javascript depreciation technique
jQuery(".submit").remove();
});
</script>
And on the controller side:
public ActionResult SearchByName (string projectName)
{
var service = Factory.GetService<IProjectService> ();
var result = service.GetProjects (projectName);
if (Request.IsAjaxRequest ())
return PartialView ("ProjectList", result);
else
{
TempData["Result"] = result;
TempData["SearchCriteria"] = projectName;
return RedirectToAction ("Index");
}
}
public ActionResult Index ()
{
IQueryable<Project> projects;
if (TempData["Result"] != null)
projects = (IQueryable<Project>)TempData["Result"];
else
{
var service = Factory.GetService<IProjectService> ();

You can either use onclick inside the button to ensure the event is preserved, or else attach the button click handler by finding the button after it is inserted. The test.html()
call will not serialize the event.
You can use the following function:
function format(number, decimals = 2, decimalSeparator = '.', thousandsSeparator = ',') {_x000D_
const roundedNumber = number.toFixed(decimals);_x000D_
let integerPart = '',_x000D_
fractionalPart = '';_x000D_
if (decimals == 0) {_x000D_
integerPart = roundedNumber;_x000D_
decimalSeparator = '';_x000D_
} else {_x000D_
let numberParts = roundedNumber.split('.');_x000D_
integerPart = numberParts[0];_x000D_
fractionalPart = numberParts[1];_x000D_
}_x000D_
integerPart = integerPart.replace(/(\d)(?=(\d{3})+(?!\d))/g, `$1${thousandsSeparator}`);_x000D_
return `${integerPart}${decimalSeparator}${fractionalPart}`;_x000D_
}_x000D_
_x000D_
// Use Example_x000D_
_x000D_
let min = 1556454.0001;_x000D_
let max = 15556982.9999;_x000D_
_x000D_
console.time('number format');_x000D_
for (let i = 0; i < 15; i++) {_x000D_
let randomNumber = Math.random() * (max - min) + min;_x000D_
let formated = format(randomNumber, 4, ',', '.'); // formated number_x000D_
_x000D_
console.log('number: ', randomNumber, '; formated: ', formated);_x000D_
}_x000D_
console.timeEnd('number format');
_x000D_
You cannot do that, see this question's answers.
You may use std:vector
instead.
These functions work well
private void setActionbarTextColor(ActionBar actBar, int color) {
String title = actBar.getTitle().toString();
Spannable spannablerTitle = new SpannableString(title);
spannablerTitle.setSpan(new ForegroundColorSpan(color), 0, spannablerTitle.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
actBar.setTitle(spannablerTitle);
}
then to use it just feed it your action bar and the new color i.e.
ActionBar actionBar = getActionBar(); // Or getSupportActionBar() if using appCompat
int red = Color.RED
setActionbarTextColor(actionBar, red);
You can use an extension function like this:
private fun ActionBar.setTitleColor(color: Int) {
val text = SpannableString(title ?: "")
text.setSpan(ForegroundColorSpan(color),0,text.length, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
title = text
}
And then apply to your ActionBar
with
actionBar?.setTitleColor(Color.RED)
wait
releases the lock and sleep
doesn't. A thread in waiting state is eligible for waking up as soon as notify
or notifyAll
is called. But in case of sleep
the thread keeps the lock and it'll only be eligible once the sleep time is over.
function Do-SendKeys {
param (
$SENDKEYS,
$WINDOWTITLE
)
$wshell = New-Object -ComObject wscript.shell;
IF ($WINDOWTITLE) {$wshell.AppActivate($WINDOWTITLE)}
Sleep 1
IF ($SENDKEYS) {$wshell.SendKeys($SENDKEYS)}
}
Do-SendKeys -WINDOWTITLE Print -SENDKEYS '{TAB}{TAB}'
Do-SendKeys -WINDOWTITLE Print
Do-SendKeys -SENDKEYS '%{f4}'
You need to allocate a block of memory and use it as an array as:
int *arr = malloc (sizeof (int) * n); /* n is the length of the array */
int i;
for (i=0; i<n; i++)
{
arr[i] = 0;
}
If you need to initialize the array with zeros you can also use the memset
function from C standard library (declared in string.h
).
memset (arr, 0, sizeof (int) * n);
Here 0
is the constant with which every locatoin of the array will be set. Note that the last argument is the number of bytes to be set the the constant. Because each location of the array stores an integer therefore we need to pass the total number of bytes as this parameter.
Also if you want to clear the array to zeros, then you may want to use calloc
instead of malloc
. calloc
will return the memory block after setting the allocated byte locations to zero.
After you have finished, free the memory block free (arr)
.
EDIT1
Note that if you want to assign a particular integer in locations of an integer array using memset
then it will be a problem. This is because memset
will interpret the array as a byte array and assign the byte you have given, to every byte of the array. So if you want to store say 11243 in each location then it will not be possible.
EDIT2
Also note why every time setting an int array to 0 with memset
may not work: Why does "memset(arr, -1, sizeof(arr)/sizeof(int))" not clear an integer array to -1? as pointed out by @Shafik Yaghmour
Why this error?
You broke the one definition rule and hence the linking error.
Suggested Solutions:
If you need the same named variable in the two cpp files then You need to use Nameless namespace(Anonymous Namespace) to avoid the error.
namespace
{
int k;
}
If you need to share the same variable across multiple files then you need to use extern
.
A.h
extern int k;
A.cpp
#include "A.h"
int k = 0;
B.cpp
#include "A.h"
//Use `k` anywhere in the file
Well, even the SELECT COUNT(*) FROM Table
will be fairly inefficient, especially on large tables, since SQL Server really can't do anything but do a full table scan (clustered index scan).
Sometimes, it's good enough to know an approximate number of rows from the database, and in such a case, a statement like this might suffice:
SELECT
SUM(used_page_count) * 8 AS SizeKB,
SUM(row_count) AS [RowCount],
OBJECT_NAME(OBJECT_ID) AS TableName
FROM
sys.dm_db_partition_stats
WHERE
OBJECT_ID = OBJECT_ID('YourTableNameHere')
AND (index_id = 0 OR index_id = 1)
GROUP BY
OBJECT_ID
This will inspect the dynamic management view and extract the number of rows and the table size from it, given a specific table. It does so by summing up the entries for the heap (index_id = 0) or the clustered index (index_id = 1).
It's quick, it's easy to use, but it's not guaranteed to be 100% accurate or up to date. But in many cases, this is "good enough" (and put much less burden on the server).
Maybe that would work for you, too? Of course, to use it in EF, you'd have to wrap this up in a stored proc or use a straight "Execute SQL query" call.

On the server, try:
netstat -an
and look to see if tcp port 22
is opened (use findstr
in Windows or grep
in Unix).
I experienced this error when I was installing Android Studio with too little memory to install everything needed. It didn't help freeing up memory or installing Android SDK my self. Re-installing Android studio with sufficient memory, made the download start when I first opened up Android Studio.
Not sure if it was because I'm working against SQL 2000 or not but I had to do this to get it to work.
string sql = "DECLARE @ID int; " +
"INSERT INTO [MyTable] ([Stuff]) VALUES (@Stuff); " +
"SET @ID = SCOPE_IDENTITY(); " +
"SELECT @ID";
var id = connection.Query<int>(sql, new { Stuff = mystuff}).Single();
In addition to the above answers, I would say for columns having no single word name, you may use:-
df[df['Product ID'].str.contains("foo") == True]
Hope this helps.

You can add more than 1 element in one shot to array using array_push,
e.g. array_push($array_name, $element1, $element2,...)
Where $element1, $element2,... are elements to be added to array.
But if you want to add only one element at one time, then other method (i.e. using $array_name[]) should be preferred.
ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations. This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. (Read More)
ExecuteScalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. It’s very fast to retrieve single values from database. (Read More)
ExecuteReader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last. (Read More)
you can press gg to locate your curser to the start of the file,then press yG to copy all the content from the start to end(G located) to buffer.good luck!
create resource layout file list_item.xml
<?xml version="1.0" encoding="utf-8"?>

and initialise adaptor like this
adapter = new ArrayAdapter<String>(this, R.layout.list_item,R.id.item_text,data_array);
I am afraid the daemon module mentioned by @Dustin didn't work for me. Instead I installed python-daemon and used the following code:
# filename myDaemon.py
import sys
import daemon
sys.path.append('/home/ubuntu/samplemodule') # till __init__.py
from samplemodule import moduleclass
with daemon.DaemonContext():
moduleclass.do_running() # I have do_running() function and whatever I was doing in __main__() in module.py I copied in it.
Running is easy
> python myDaemon.py
just for completeness here is samplemodule directory content
>ls samplemodule
__init__.py __init__.pyc moduleclass.py
The content of moduleclass.py can be
class moduleclass():
...
def do_running():
m = moduleclass()
# do whatever daemon is required to do.
It should be mentioned that it is an option to completely leave authentication issues to the front controller, e.g. an Apache Webserver and evaluate the HttpServletRequest.getRemoteUser() instead, which is the JAVA representation for the REMOTE_USER environment variable. This allows also sophisticated log in designs such as Shibboleth authentication. Filtering Requests to a servlet container through a web server is a good design for production environments, often mod_jk is used to do so.
