Javascripts .call()
and .apply()
methods allow you to set the context for a function.
var myfunc = function(){
alert(this.name);
};
var obj_a = {
name: "FOO"
};
var obj_b = {
name: "BAR!!"
};
Now you can call:
myfunc.call(obj_a);
Which would alert FOO
. The other way around, passing obj_b
would alert BAR!!
. The difference between .call()
and .apply()
is that .call()
takes a comma separated list if you're passing arguments to your function and .apply()
needs an array.
myfunc.call(obj_a, 1, 2, 3);
myfunc.apply(obj_a, [1, 2, 3]);
Therefore, you can easily write a function hook
by using the apply()
method. For instance, we want to add a feature to jQuerys .css()
method. We can store the original function reference, overwrite the function with custom code and call the stored function.
var _css = $.fn.css;
$.fn.css = function(){
alert('hooked!');
_css.apply(this, arguments);
};
Since the magic arguments
object is an array like object, we can just pass it to apply()
. That way we guarantee, that all parameters are passed through to the original function.
If you have your MySQL server up and running, then you just need a client to connect to it and start practicing. One is the mysql-client
, which is a command-line tool, or you can use phpMyAdmin
, which is a web-based tool.

You've got several options:
x
ecute permissions on that directory.x
ecute permissions.
chmod(1)
to change the permissions orsetfacl(1)
command to add an access control list entry for your user account. (This also requires mounting the filesystem with the acl
option; see mount(8)
and fstab(5)
for details on the mount parameter.)It's impossible to suggest the correct approach without knowing more about the problem; why are the directory permissions set the way they are? Why do you need access to that directory?
From the Java EE documentation:
public abstract boolean unique
(Optional) Whether the property is a unique key. This is a shortcut for the UniqueConstraint annotation at the table level and is useful for when the unique key constraint is only a single field. This constraint applies in addition to any constraint entailed by primary key mapping and to constraints specified at the table level.
See doc
You can fake it like this:
-- with column headings
select column1, column2 from some_table;
-- without column headings
select column1 as '', column2 as '' from some_table;
This will give the canonical path (will resolve symlinks): realpath FILENAME
If you want canonical path to the symlink itself, then: realpath -s FILENAME
You can use this magic Spring Test annotation :
@TestPropertySource(properties = { "my.spring.property=20" })
see org.springframework.test.context.TestPropertySource
For example, this is the test class :
@ContextConfiguration(classes = { MyTestClass.Config.class })
@TestPropertySource(properties = { "my.spring.property=20" })
public class MyTestClass {
public static class Config {
@Bean
MyClass getMyClass() {
return new MyClass ();
}
}
@Resource
private MyClass myClass ;
@Test
public void myTest() {
...
And this is the class with the property :
@Component
public class MyClass {
@Value("${my.spring.property}")
private int mySpringProperty;
...
above answers In simple words,
you have to register under @NgModule
's
declarations: [
AppComponent, YourNewComponentHere
]
of app.module.ts
do not forget to import
that component.
If the class implements comparable, you could also do
int compRes = a.compareTo(b);
if(compRes < 0 || compRes > 0)
System.out.println("not equal");
else
System.out.println("equal);
doesn't use a !
, though not particularly useful, or readable....
You could use a PowerShell command. Stick this in your batch script and it'll create a shortcut to %~f0
in %userprofile%\Start Menu\Programs\Startup
:
powershell "$s=(New-Object -COM WScript.Shell).CreateShortcut('%userprofile%\Start Menu\Programs\Startup\%~n0.lnk');$s.TargetPath='%~f0';$s.Save()"
If you prefer not to use PowerShell, you could use mklink
to make a symbolic link. Syntax:
mklink saveShortcutAs targetOfShortcut
See mklink /?
in a console window for full syntax, and this web page for further information.
In your batch script, do:
mklink "%userprofile%\Start Menu\Programs\Startup\%~nx0" "%~f0"
The shortcut created isn't a traditional .lnk file, but it should work the same nevertheless. Be advised that this will only work if the .bat file is run from the same drive as your startup folder. Also, apparently admin rights are required to create symbolic links.
The solution is to set the default value in your .elem. But this annimation work fine with -moz but not yet implement in -webkit

I have a dataset in my app and I went to set changes (deleting a row) to it but ds.tabales["TableName"]
is read only. Then I found this solution.
It's a wpf C#
app,
try {
var results = from row in ds.Tables["TableName"].AsEnumerable() where row.Field<string>("Personalid") == "47" select row;
foreach (DataRow row in results) {
ds.Tables["TableName"].Rows.Remove(row);
}
}
In JUnit 4, another option for you may be to create an annotation to denote that the test needs to meet your custom criteria, then extend the default runner with your own and using reflection, base your decision on the custom criteria. It may look something like this:
public class CustomRunner extends BlockJUnit4ClassRunner {
public CTRunner(Class<?> klass) throws initializationError {
super(klass);
}
@Override
protected boolean isIgnored(FrameworkMethod child) {
if(shouldIgnore()) {
return true;
}
return super.isIgnored(child);
}
private boolean shouldIgnore(class) {
/* some custom criteria */
}
}
savefig
has its own parameter for facecolor

I think an even easier way than the accepted answer is to set them globally just once, instead of putting facecolor=fig.get_facecolor()
every time:
plt.rcParams['axes.facecolor']='red'
plt.rcParams['savefig.facecolor']='red'
This works perfectly for me

For some reason none of the answers worked for me so I had to override the restoreState method without calling super in my fragmentStatePagerAdapter. Code:
private class MyAdapter extends FragmentStatePagerAdapter {
// [Rest of implementation]
@Override

}
Actually this will give you repeated indices np.random.random_integers(0, len(df), N)
where N

Update March, 26th 2012, release date of Notepad++ 6.0:
OMG, it actually does work now!!!
Original answer 2008 (Notepad++ 4.x) - 2009-2010-2011 (Notepad++ 5.x)
Actually no, it does not seem to work with regexp...
But if you have Notepad++ 5.x, you can use the 'extended' search mode and look for \r\n
. That does find all your CRLF
.
(I realize this is the same answer than the others, but again, 'extended mode' is only available with Notepad++ 4.9, 5.x and more)
Since April 2009, you have a wiki article on the Notepad++ site on this topic:
"How To Replace Line Ends, thus changing the line layout".
(mentioned by georgiecasey in his/her answer below)
Some relevant extracts includes the following search processes:
Simple search (Ctrl+F), Search Mode =
Normal
You can select an
EOL
in the editing window.
- Just move the cursor to the end of the line, and type Shift+Right Arrow.
- or, to select
EOL
with the mouse, start just at the line end and drag to the start of the next line; dragging to the right of theEOL
won't work. You can manually copy theEOL
and paste it into the field for Unix files (LF
-only).Simple search (Ctrl+F), Search Mode = Extended
The "Extended" option shows
\n
and\r
as characters that could be matched.
As with the Normal search mode, Notepad++ is looking for the exact character.
Searching for\r
in a UNIX-format file will not find anything, but searching for\n
will. Similarly, a Macintosh-format file will contain\r
but not\n
.Simple search (Ctrl+F), Search Mode = Regular expression
Regular expressions use the characters
^
and$
to anchor the match string to the beginning or end of the line. For instance, searching forreturn;$
will find occurrences of "return;" that occur with no subsequent text on that same line. The anchor characters work identically in all file formats.
The '.' dot metacharacter does not match line endings.[Tested in Notepad++ 5.8.5]: a regular expression search with an explicit
\r
or\n
does not work (contrary to the Scintilla documentation).
Neither does a search on an explicit (pasted) LF, or on the (invisible) EOL characters placed in the field when an EOL is selected. Advanced search (Ctrl+R) without regexpCtrl+M will insert something that matches newlines. They will be replaced by the replace string.
I recommend this method as the most reliable, unless you really need to use regex.
As an example, to remove every second newline in a double spaced file, enter Ctrl+M twice in the search string box, and once in the replace string box.Advanced search (Ctrl+R) with Regexp.
Neither Ctrl+M,
$
nor\r\n
are matched.
The same wiki also mentions the Hex editor alternative:
- Type the new string at the beginning of the document.
- Then select to view the document in Hex mode.
- Select one of the new lines and hit Ctrl+H.
- While you have the Replace dialog box up, select on the background the new replacement string and Ctrl+C copy it to paste it in the Replace with text input.
- Then Replace or Replace All as you wish.
Note: the character selected for new line usually appears as
0a
.
It may have a different value if the file is in Windows Format. In that case you can always go toEdit -> EOL Conversion -> Convert to Unix Format
, and after the replacement switch it back andEdit -> EOL Conversion -> Convert to Windows Format
.

Here's a one-liner using Maven:
mvn dependency:get -Dartifact=mysql:mysql-connector-java:5.1.38
Then, with default settings, it's available in:
$HOME/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar
Just replace the version number if you need a different one.
I like this trick:
echo ${RANDOM:0:1} # random number between 1 and 9
echo ${RANDOM:0:2} # random number between 1 and 99

Use .unshift()
to add to the beginning of an array.
TheArray.unshift(TheNewObject);
See MDN for doc on unshift()
and here for doc on other array methods.
FYI, just like there's .push()
and .pop()
for the end of the array, there's .shift()
and .unshift()
for the beginning of the array.
You can use the str.split
method: string.split('__')
>>> "MATCHES__STRING".split("__")
['MATCHES', 'STRING']
There are numerous ways to store credentials while still using boto3.resource(). I'm using the AWS CLI method myself. It works perfectly.
There were (at time of posting) one or two little typos in the accepted answer above, so here's the cleaned up version. In this example I'm stopping the CPU profiler when receiving Ctrl+C.
// capture ctrl+c and stop CPU profiler
c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
go func() {
for sig := range c {
log.Printf("captured %v, stopping profiler and exiting..", sig)
pprof.StopCPUProfile()
os.Exit(1)
}
}()
With ES6 arrow functions it will be like this:
//Let's say we have these cars
let cars = [ { brand: 'Porsche', top_speed: 260 },
{ brand: 'Benz', top_speed: 110 },
{ brand: 'Fiat', top_speed: 90 },
{ brand: 'Aston Martin', top_speed: 70 } ]
Array.prototype.sort()
can accept a comparator function (here I used arrow notation, but ordinary functions work the same):
let sortedByBrand = [...cars].sort((first, second) => first.brand > second.brand)
// [ { brand: 'Aston Martin', top_speed: 70 },
// { brand: 'Benz', top_speed: 110 },
// { brand: 'Fiat', top_speed: 90 },
// { brand: 'Porsche', top_speed: 260 } ]
The above approach copies the contents of cars array into a new one and sorts it alphabetically based on brand names. Similarly, you can pass a different function:
let sortedBySpeed =[...cars].sort((first, second) => first.top_speed > second.top_speed)
//[ { brand: 'Aston Martin', top_speed: 70 },
// { brand: 'Fiat', top_speed: 90 },
// { brand: 'Benz', top_speed: 110 },
// { brand: 'Porsche', top_speed: 260 } ]
If you don't mind mutating the orginal array cars.sort(comparatorFunction)
will do the trick.

from the S3 API, per the docs the contents of your file are located in the Body
property, which you can see from your sample output. You should have code that looks something like the following
const aws = require('aws-sdk');
const s3 = new aws.S3(); // Pass in opts to S3 if necessary
var getParams = {
Bucket: 'abc', // your bucket name,
Key: 'abc.txt' // path to the object you're looking for
}
s3.getObject(getParams, function(err, data) {
// Handle any error and exit
if (err)
return err;
// No error happened
// Convert Body from a Buffer to a String
let objectData = data.Body.toString('utf-8'); // Use the encoding necessary
});
You may not need to create a new buffer from the data.Body
object but if you need you can use the sample above to achieve that.
byte[] byteArray = rs.getBytes("columnname");
Bitmap bm = BitmapFactory.decodeByteArray(byteArray, 0 ,byteArray.length);
In layman terms we can say that Persistence Context is an environment where entities are managed, i.e it syncs "Entity" with the database.
final ListView lv = (ListView) findViewById(R.id.ListView01);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));
}
});
I hope this fixes your problem.
I wrote this one today while trying to recreate _.sortBy
in TypeScript, and thought I would leave it for anyone in need.
// ** Credits for getKeyValue at the bottom **
export const getKeyValue = <T extends {}, U extends keyof T>(key: U) => (obj: T) => obj[key]
export const sortBy = <T extends {}>(index: string, list: T[]): T[] => {
return list.sort((a, b): number => {
const _a = getKeyValue<keyof T, T>(index)(a)
const _b = getKeyValue<keyof T, T>(index)(b)
if (_a < _b) return -1
if (_a > _b) return 1
return 0
})
}
It expects an array of generic type T, hence the cast for <T extends {}>
, as well as typing the parameter and function return type with T[]
const x = [{ label: 'anything' }, { label: 'goes'}]
const sorted = sortBy('label', x)
** getByKey

RABL is probably the nicest solution to this that I've seen if you're looking for a cleaner alternative to ERb syntax. json_builder and argonaut, which are other solutions, both seem somewhat outdated and won't work with Rails 3.1 without some patching.
RABL is available via a gem or check out the GitHub repository; good examples too
You can define the drawables that are used for the background, and the switcher part like this:
<Switch
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:thumb="@drawable/switch_thumb"
android:track="@drawable/switch_bg" />
Now you need to create a selector that defines the different states for the switcher drawable. Here the copies from the Android sources:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:drawable="@drawable/switch_thumb_disabled_holo_light" />
<item android:state_pressed="true" android:drawable="@drawable/switch_thumb_pressed_holo_light" />
<item android:state_checked="true" android:drawable="@drawable/switch_thumb_activated_holo_light" />
<item android:drawable="@drawable/switch_thumb_holo_light" />
</selector>
This defines the thumb drawable, the image that is moved over the background. There are four ninepatch images used for the slider:
The deactivated version (xhdpi version that Android is using)
The pressed slider:
The activated slider (on state):
The default version (off state):
There are also three different states for the background that are defined in the following selector:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:drawable="@drawable/switch_bg_disabled_holo_dark" />
<item android:state_focused="true" android:drawable="@drawable/switch_bg_focused_holo_dark" />
<item android:drawable="@drawable/switch_bg_holo_dark" />
</selector>
The deactivated version:
The focused version:
And the default version:
To have a styled switch just create this two selectors, set them to your Switch View and then change the seven images to your desired style.
Your command line should have a -d/--data inserted before the string you want to send in the PUT, and you want to set the Content-Type and not Accept.
curl -H 'Content-Type: application/json' -X PUT -d '[JSON]' \

Using the exact JSON data from the question, the full command line would become:
curl -H 'Content-Type: application/json' -X PUT \
-d '{"tags":["tag1","tag2"],
"question":"Which band?",
"answers":[{"id":"a0","answer":"Answer1"},
{"id":"a1","answer":"answer2"}]}' \

This is the best explanation with code in PHP I have found so far:
http://code.tutsplus.com/tutorials/managing-cron-jobs-with-php--net-19428
In short:
Although the syntax of scheduling a new job may seem daunting at first glance, it's actually relatively simple to understand once you break it down. A cron job will always have five columns each of which represent a chronological 'operator' followed by the full path and command to execute:
* * * * * home/path/to/command/the_command.sh
Each of the chronological columns has a specific relevance to the schedule of the task. They are as follows:
Minutes represents the minutes of a given hour, 0-59 respectively.
Hours represents the hours of a given day, 0-23 respectively.
Days represents the days of a given month, 1-31 respectively.
Months represents the months of a given year, 1-12 respectively.
Day of the Week represents the day of the week, Sunday through Saturday, numerically, as 0-6 respectively.
So, for example, if one wanted to schedule a task for 12am on the first day of every month it would look something like this:
0 0 1 * * home/path/to/command/the_command.sh
If we wanted to schedule a task to run every Saturday at 8:30am we'd write it as follows:
30 8 * * 6 home/path/to/command/the_command.sh
There are also a number of operators which can be used to customize the schedule even further:
Commas is used to create a comma separated list of values for any of the cron columns.
Dashes is used to specify a range of values.
Asterisksis used to specify 'all' or 'every' value

At least for the GitHub Flavoured Markdown, you can give the illusion by making all the non-header row entries bold with the regular __
or **
formatting:
|Regular | text | in header | turns bold |
|-|-|-|-|
| __So__ | __bold__ | __all__ | __table entries__ |
| __and__ | __it looks__ | __like a__ | __"headerless table"__ |
This command did it for me:
zip -r Target.zip Source -x "*.DS_Store"
Target.zip
is the zip file to create. Source
is the source file/folder to zip up. And the _x
parameter specifies the file/folder to not include. If the above doesn't work for whatever reason, try this instead:
zip -r Target.zip Source -x "*.DS_Store" -x "__MACOSX"
I dont understand the frustrations. Why not just make a broadcastreceiver that filters for this intent:
android.provider.Telephony.MMS_RECEIVED
I checked a little further and you might need system level access to get this (rooted phone).
EDIT: The solution below is only for HTML "fragments" since html,head and body are removed. I guess the solution for this question is DOMParser's parseFromString() method.
For HTML fragments, the solutions listed here works for most HTML, however for certain cases it won't work.
For example try parsing <td>Test</td>
. This one won't work on the div.innerHTML solution nor DOMParser.prototype.parseFromString nor range.createContextualFragment solution. The td tag goes missing and only the text remains.
Only jQuery handles that case well.
So the future solution (MS Edge 13+) is to use template tag:
function parseHTML(html) {
var t = document.createElement('template');
t.innerHTML = html;
return t.content.cloneNode(true);
}
var documentFragment = parseHTML('<td>Test</td>');
For older browsers I have extracted jQuery's parseHTML() method into an independent gist - https://gist.github.com/Munawwar/6e6362dbdf77c7865a99

In case anyone else comes across this problem, if you have already laid the page out, I would recommend using media queries to set up your print page. You can then simply attach a print function to your html button and in your component call window.print();
component.html:
<div class="doNotPrint">
Header is here.
</div>
<div>
all my beautiful print-related material is here.
</div>
<div class="doNotPrint">
my footer is here.
<button (click)="onPrint()">Print</button>
</div>
component.ts:
onPrint(){
window.print();
}
component.css:
@media print{
.doNotPrint{display:none !important;}
}
You can optionally also add other elements / sections you do not wish to print in the media query.
You can change the document margins and all in the print query as well, which makes it quite powerful. There are many articles online. Here is one that seems comprehensive: https://www.sitepoint.com/create-a-customized-print-stylesheet-in-minutes/ It also means you don't have to create a separate script to create a 'print version' of the page or use lots of javascript.
if you guys want to make a non-overflow scrollview or listview, just but it on a RelativeLayout with a topview and bottomview on top and bottom for it:

android:layout_above="@+id/topview"
android:layout_below="@+id/bottomview" >
This question comes in top of Google search when you find "golang current time format" so, for all the people that want to use another format, remember that you can always call to:
t := time.Now()
t.Year()
t.Month()
t.Day()
t.Hour()
t.Minute()
t.Second()
For example, to get current date time as "YYYY-MM-DDTHH:MM:SS" (for example 2019-01-22T12:40:55) you can use these methods with fmt.Sprintf:
t := time.Now()
formatted := fmt.Sprintf("%d-%02d-%02dT%02d:%02d:%02d",
t.Year(), t.Month(), t.Day(),
t.Hour(), t.Minute(), t.Second())
As always, remember that docs are the best source of learning: https://golang.org/pkg/time/
Another possible way:
open my $fh, '<', "filename";
read $fh, my $string, -s $fh;
close $fh;
Definition and Usage
The tag defines a division or a section in an HTML document.
The tag is used to group block-elements to format them with styles. http://www.w3schools.com/tags/tag_div.asp
Also DIV - MDN
The HTML element (or HTML Document Division Element) is the generic container for flow content, which does not inherently represent anything. It can be used to group elements for styling purposes (using the class or id attributes), or because they share attribute values, such as lang. It should be used only when no other semantic element (such as or ) is appropriate.
You can use div inside form, if you are talking about using div instead of table, then google about Tableless web design

Then in the parent of my testng unit test class I created a method:
protected TestAppender testAppender;
@BeforeClass
public void setupLogsForTesting() {
Logger root = (Logger)LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
testAppender = (TestAppender)root.getAppender("TEST");
if (testAppender != null) {
testAppender.clear();
}
}
I have a logback-test.xml file defined in src/test/resources and I added a test appender:
<appender name="TEST" class="com.intuit.icn.TestAppender">
<encoder>
<pattern>%m%n</pattern>
</encoder>
</appender>
and added this appender to the root appender:
<root>
<level value="error" />
<appender-ref ref="STDOUT" />
<appender-ref ref="TEST" />
</root>
Now in my test classes that extend from my parent test class I can get the appender and get the last message logged and verify the message, the level, the throwable.
ILoggingEvent lastEvent = testAppender.getLastEvent();
assertEquals(lastEvent.getMessage(), "...");
assertEquals(lastEvent.getLevel(), Level.WARN);
assertEquals(lastEvent.getThrowableProxy().getMessage(), "...");
Your question is underspecified. Strictly, that example is a syntax error. However, mbstowcs
is probably what you're looking for.
It is a C-library function and operates on buffers, but here's an easy-to-use idiom, courtesy of Mooing Duck:
std::wstring ws(s.size(), L' '); // Overestimate number of code points.
ws.resize(::mbstowcs_s(&ws[0], ws.size(), s.c_str(), s.size())); // Shrink to fit.
You're looking for RAISERROR
.
From MSDN:
Generates an error message and initiates error processing for the session. RAISERROR can either reference a user-defined message stored in the sys.messages catalog view or build a message dynamically. The message is returned as a server error message to the calling application or to an associated CATCH block of a TRY…CATCH construct.
CodeProject has a good article that also describes in-depth the details of how it works and how to use it.
As Ben said, you are POSTing your request ( HttpMethod.Post specified in your code )
The querystring (get) parameters included in your url probably will not do anything.
Try this:
string url = "http://myserver/method";
string content = "param1=1¶m2=2";
HttpClientHandler handler = new HttpClientHandler();
HttpClient httpClient = new HttpClient(handler);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
HttpResponseMessage response = await httpClient.SendAsync(request,content);

Once you have the file-loader configured in the webpack.config, whenever you use import/require it tests the path against all loaders, and in case there is a match it passes the contents through that loader. In your case, it matched
{
test: /\.(jpe?g|png|gif|svg)$/i,
loader: "file-loader?name=/public/icons/[name].[ext]"
}
// For newer versions of Webpack it should be
{
test: /\.(jpe?g|png|gif|svg)$/i,
loader: 'file-loader',
options: {
name: '/public/icons/[name].[ext]'
}
}
and therefore you see the image emitted to
dist/public/icons/imageview_item_normal.png
which is the wanted behavior.
The reason you are also getting the hash file name, is because you are adding an additional inline file-loader. You are importing the image as:
'file!../../public/icons/imageview_item_normal.png'.
Prefixing with file!
, passes the file into the file-loader again, and this time it doesn't have the name configuration.
So your import should really just be:
import img from '../../public/icons/imageview_item_normal.png'
Update
As noted by @cgatian, if you actually want to use an inline file-loader, ignoring the webpack global configuration, you can prefix the import with two exclamation marks (!!):
import '!!file!../../public/icons/imageview_item_normal.png'.
After importing the png, the img
variable only holds the path the file-loader "knows about", which is public/icons/[name].[ext]
(aka "file-loader? name=/public/icons/[name].[ext]"
). Your output dir "dist" is unknown.
You could solve this in two ways:
publicPath
property to your output config, that points to your output directory (in your case ./dist).Example:
output: {
path: PATHS.build,
filename: 'app.bundle.js',
publicPath: PATHS.build
},
Just change the following values at "eclipse.ini" file to the following:
-Xms1024m
-Xmx2048m
Note:
You need to have
#include <string>
in the header file too.The forward declaration on it's own doesn't do enough.
Also strongly consider header guards for your header files to avoid possible future problems as your project grows. So at the top do something like:
#ifndef THE_FILE_NAME_H
#define THE_FILE_NAME_H
/* header goes in here */
#endif
This will prevent the header file from being #included multiple times, if you don't have such a guard then you can have issues with multiple declarations.

If you are using Django Framework, it has such a property to cache a view or response of API's
using @cache_page(time)
and there can be other options as well.
Example:
@cache_page(60 * 15, cache="special_cache")
def my_view(request):
...
More details can be found here.
how about:
scope.$watch(function() {
return {
a: thing-one,
b: thing-two,
c: red-fish,
d: blue-fish
};
}, listener...);
A possible reason for an empty $_POST
is that the request is not POST
, or not POST
anymore... It may have started out as post, but encountered a 301
or 302
redirect somewhere, which is switched to GET
!
Inspect $_SERVER['REQUEST_METHOD']
to check if this is the case.

List<int> right = new List<int>();
int pivotIndex = list.Count / 2;
int pivot = list[pivotIndex]; //arbitrary
for (int i = 0; i < list.Count && i != pivotIndex; i++)
{
int currentEl = list[i];
if (currentEl < pivot)
left.Add(currentEl);
else
right.Add(currentEl);
}
if (k == left.Count + 1)
return pivot;
if (left.Count < k)
return kthElInUnsortedList(right, k - left.Count - 1);
else

rebellion's answer above won't actually work, because to CSS, 'background-position' is actually shorthand for 'background-position-x' and 'background-position-y' so the correct version of his code would be:
$(document).ready(function(){
$('#submenu li').hover(function(){
$('#carousel').css('background-position-x', newValueX);
$('#carousel').css('background-position-y', newValue);
}, function(){
$('#carousel').css('background-position-x', oldValueX);
$('#carousel').css('background-position-y', oldValueY);
});
});
It took about 4 hours of banging my head against it to come to that aggravating realization.
you need to run something like this
GRANT Execute ON [dbo].fnc_whatEver TO [domain\user]
This worked for me Angular cli 6.x:

constructor(private artistService: ArtistService, private router: Router) { }
selectRow(id: number): void{

}
Just use if

string cat = "cat";
string human = "human";
cout << cat.compare(human) << endl;
This code will give -1 as a result. This is due to the first non-matching character of the compared string 'h' is lower or appears after 'c' in alphabetical order, even though the compared string, 'human' is longer than 'cat'.
I find the return value described in cplusplus.com is more accurate which are-:
0 : They compare equal
<0 : Either the value of the first character that does not match is lower in the compared string, or all compared characters match but the compared string is shorter.
more than 0 : Either the value of the first character that does not match is greater in the compared string, or all compared characters match but the compared string is longer.
Moreover, IMO cppreference.com's description is simpler and so far best describe to my own experience.
negative value if
*this
appears before the character sequence specified by the arguments, in lexicographical orderzero if both character sequences compare equivalent
positive value if
*this
appears after the character sequence specified by the arguments, in lexicographical order
You might need to uninstall antivirus (in my case I had to get rid of Avast).

The percentage setting does not take into account the original image size. From w3schools :
In HTML 4.01, the width could be defined in pixels or in % of the containing element. In HTML5, the value must be in pixels.
Also, good practice advice from the same source :
Tip: Downsizing a large image with the height and width attributes forces a user to download the large image (even if it looks small on the page). To avoid this, rescale the image with a program before using it on a page.

Be aware of the "date=iso
" format: it isn't exactly ISO 8601.
See commit "466fb67" from Beat Bolli (bbolli
), for Git 2.2.0 (November 2014)
Git's "ISO" date format does not really conform to the ISO 8601 standard due to small differences, and it cannot be parsed by ISO 8601-only parsers, e.g. those of XML toolchains.
The output from "
--date=iso
" deviates from ISO 8601 in these ways:
- a space instead of the
T
date/time delimiter- a space between time and time zone
- no colon between hours and minutes of the time zone
Add a strict ISO 8601 date format for displaying committer and author dates.
Use the '%aI
' and '%cI
' format specifiers and add '--date=iso-strict
' or '--date=iso8601-strict
' date format names.
See this thread for discussion.
Remember that your img is not really a DOM element but a javascript expression.
This is a JSX attribute expression. Put curly braces around the src string expression and it will work. See http://facebook.github.io/react/docs/jsx-in-depth.html#attribute-expressions
In javascript, the class attribute is reference using className. See the note in this section: http://facebook.github.io/react/docs/jsx-in-depth.html#react-composite-components
/** @jsx React.DOM */
var Hello = React.createClass({
render: function() {
return <div><img src={'http://placehold.it/400x20&text=slide1'} alt="boohoo" className="img-responsive"/><span>Hello {this.props.name}</span></div>;
}
});
React.renderComponent(<Hello name="World" />, document.body);
The m2e plugin generate project configuration every time when you update project (Maven->Update Project ... That action overrides facets setting configured manually in Eclipse. Therefore you have to configure it on pom level. By setting properties in pom file you can tell m2e plugin what to do.
Enable/Disable the JAX-RS/JPA/JSF Configurators at the pom.xml level The optional JAX-RS, JPA and JSF configurators can be enabled or disabled at a workspace level from Window > Preferences > Maven > Java EE Integration. Now, you can have a finer grain control on these configurators directly from your pom.xml properties :
Adding false in your pom properties section will disable the JAX-RS configurator Adding false in your pom properties section will disable the JPA configurator Adding false in your pom properties section will disable the JSF configurator The pom settings always override the workspace preferences. So if you have, for instance the JPA configurator disabled at the workspace level, using true will enable it on your project anyway. (http://wiki.eclipse.org/M2E-WTP/New_and_Noteworthy/1.0.0)
It's the identifier for your current session in PHP. If you delete it, you won't be able to access/make use of session variables. I'd suggest you keep it.
You can't put a div
directly inside a table
, like this:
<!-- INVALID -->
<table>
<div>
Hello World

</table>
Putting a div
inside a td
or th
element is fine, however:
<!-- VALID -->
<table>
<tr>
<td>
<div>
Hello World
</div>
</td>
</tr>
</table>
Simply put:
t1.join()
returns after t1
is completed.
It doesn't do anything to thread t1
, except wait for it to finish.
Naturally, code following
t1.join()
will be executed only after
t1.join()
returns.

The return value from $mail refers only to whether or not your server's mailing system accepted the message for delivery, and does not and can not in any way know whether or not you are providing valid arguments. For example, the return value would be false if sendmail failed to load (e.g. if it wasn't installed properly), but would return true if sendmail loaded properly but the recipient address doesn't exist.
I confirm this because after some failed attempts to use mail()
in my PHP scripts, it turns that sendmail
was not installed on my machine, however the php.ini variable sendmail_path
was /usr/sbin/sendmail -t -i
1- I installed sendmail from my package manager shell> dnf install sendmail
2- I started it shell> service sendmail start
3- Now if any PHP mail()
function fails I find the errors of the sendmail

The get
method of the HashMap
is returning an Object
, but the variable current
is expected to take a ArrayList
:
ArrayList current = new ArrayList();
// ...
current = dictMap.get(dictCode);
For the above code to work, the Object
must be cast to an ArrayList
:
ArrayList current = new ArrayList();
// ...
current = (ArrayList)dictMap.get(dictCode);
However, probably the better way would be to use generic collection objects in the first place:
HashMap<String, ArrayList<Object>> dictMap =
new HashMap<String, ArrayList<Object>>();
// Populate the HashMap.
ArrayList<Object> current = new ArrayList<Object>();
if(dictMap.containsKey(dictCode)) {
current = dictMap.get(dictCode);
}
The above code is assuming that the ArrayList
has a list of Object
s, and that should be changed as necessary.
For more information on generics, The Java Tutorials has a lesson on generics.
you can use Array.select or Array.index to do that.
Previous answers advise using the tarfile
Python module for creating a .tar.gz
file in Python. That's obviously a good and Python-style solution, but it has serious drawback in speed of the archiving. This question mentions that tarfile
is approximately two times slower than the tar
utility in Linux. According to my experience this estimation is pretty correct.
So for faster archiving you can use the tar
command using subprocess
module:
subprocess.call(['tar', '-czf', output_filename, file_to_archive])
The json is kind of odd, it's like the students are properties of the "GetQuestion" object, it should be easy to be a List.....
About the libraries you could use are.
And there could be many more, but that are what I've used
About the json I don't now maybe something like this
public class GetQuestions
{
public List<Student> Questions { get; set; }
}
public class Student
{
public string Code { get; set; }
public string Questions { get; set; }
}
void Main()
{
var gq = new GetQuestions
{
Questions = new List<Student>
{
new Student {Code = "s1", Questions = "Q1,Q2"},
new Student {Code = "s2", Questions = "Q1,Q2,Q3"},
new Student {Code = "s3", Questions = "Q1,Q2,Q4"},
new Student {Code = "s4", Questions = "Q1,Q2,Q5"},
}
};
//Using Newtonsoft.json. Dump is an extension method of [Linqpad][4]
JsonConvert.SerializeObject(gq).Dump();
}
and the result is this
{
"Questions":[
{"Code":"s1","Questions":"Q1,Q2"},
{"Code":"s2","Questions":"Q1,Q2,Q3"},
{"Code":"s3","Questions":"Q1,Q2,Q4"},
{"Code":"s4","Questions":"Q1,Q2,Q5"}
]
}
Yes I know the json is different, but the json that you want with dictionary.
void Main()
{
var f = new Foo
{
GetQuestions = new Dictionary<string, string>
{
{"s1", "Q1,Q2"},
{"s2", "Q1,Q2,Q3"},
{"s3", "Q1,Q2,Q4"},
{"s4", "Q1,Q2,Q4,Q6"},
}
};
JsonConvert.SerializeObject(f).Dump();
}
class Foo
{
public Dictionary<string, string> GetQuestions { get; set; }
}
And with Dictionary is as you want it.....
{
"GetQuestions":
{
"s1":"Q1,Q2",
"s2":"Q1,Q2,Q3",
"s3":"Q1,Q2,Q4",
"s4":"Q1,Q2,Q4,Q6"
}
}
The MemoryError
exception that you are seeing is the direct result of running out of available RAM. This could be caused by either the 2GB per program limit imposed by Windows (32bit programs), or lack of available RAM on your computer. (This link is to a previous question).
You should be able to extend the 2GB by using 64bit copy of Python, provided you are using a 64bit copy of windows.
The IndexError
would be caused because Python hit the MemoryError
exception before calculating the entire array. Again this is a memory issue.
To get around this problem you could try to use a 64bit copy of Python or better still find a way to write you results to file. To this end look at numpy's memory mapped arrays.
You should be able to run you entire set of calculation into one of these arrays as the actual data will be written disk, and only a small portion of it held in memory.
I'll just throw in a JS (ES6) answer, in case someone is looking for it:
Array.from(document.querySelectorAll(".myClass:not(#myId)")).forEach((el,i) => {
doSomething(el);
}
Update (this may have been possible when I posted the original answer, but adding this now anyway):
document.querySelectorAll(".myClass:not(#myId)").forEach((el,i) => {
doSomething(el);
});
This gets rid of the Array.from
usage.
document.querySelectorAll
returns a NodeList
.
Read here to know more about how to iterate on it (and other things): https://developer.mozilla.org/en-US/docs/Web/API/NodeList
int [] SouceArray1 = new int[] {2,1,3};
int [] SourceArray2 = new int[] {4,5,6};
int [] targetArray = new int [SouceArray1.Length + SourceArray2.Length];
SouceArray1.CopyTo(targetArray,0);
SourceArray2.CopyTo(targetArray,SouceArray1.Length) ;
foreach (int i in targetArray) Console.WriteLine(i + " ");
Using the above code two Arrays can be easily merged.
Another way:
Checkout the branch you want to revert, then reset your local working copy back to the commit that you want to be the latest one on the remote server (everything after it will go bye-bye). To do this, in SourceTree, I right-clicked on the and selected "Reset BRANCHNAME to this commit".
Then navigate to your repository's local directory and run this command:
git -c diff.mnemonicprefix=false -c core.quotepath=false push -v -f -- tags REPOSITORY_NAME BRANCHNAME:BRANCHNAME
This will erase all commits after the current one in your local repository but only for that one branch.
It depends on the scenario. If you only want to compute the age of a person, then use a function since you want to implement a single specific behaviour.
But if you want to create an object, that contains the date of birth of a person (and possibly other data), allows to modify it, then computing the age could be one of many operations related to the person and it would be sensible to use a class instead.
Classes provide a way to merge together some data and related operations. If you have only one operation on the data then using a function and passing the data as argument you will obtain an equivalent behaviour, with less complex code.
Note that a class of the kind:
class A(object):
def __init__(self, ...):
#initialize
def a_single_method(self, ...):
#do stuff
isn't really a class, it is only a (complicated)function. A legitimate class should always have at least two methods(without counting __init__
).
Remove a file with .dat extension in workspace/.metadata/.plugins/org.eclipse.wst.jsdt.core/ and then close eand open eclipse, maybe you cannot close eclipse, force it, with pkill -f eclipse if you are on linux or similar.
This solution avoid to import all of existents projects.
Are you referring to the favicon?
Upload a 16x16px ico to your site, and link it in your head
section.
<link rel="shortcut icon" href="/favicon.ico" />
There are a multitude of sites that help you convert images into .ico format too. This is just the first one I saw on Google. http://www.favicon.cc/
Create a class and give it an __init__
method:
class Student:
def __init__(self, name, age, major):
self.name = name
self.age = age
self.major = major
def is_old(self):
return self.age > 100
Now, you can initialize an instance of the Student
class:
>>> s = Student('John', 88, None)
>>> s.name
'John'
>>> s.age
88
Although I'm not sure why you need a make_student
student function if it does the same thing as Student.__init__
.
We can also read by the name.
Say we have saved the value with name 'user' like this
localStorage.setItem('user', user_Detail);
Then we can read it by using
localStorage.getItem('user');
I used it and it is working smooth, no need to do the for loop
You should also consider that in some Opera versions onload is fired several times and add some hooks:
// fixing Opera 9.26, 10.00
if (doc.readyState && doc.readyState != 'complete') {
// Opera fires load event multiple times
// Even when the DOM is not ready yet
// this fix should not affect other browsers
return;
}
// fixing Opera 9.64
if (doc.body && doc.body.innerHTML == "false") {
// In Opera 9.64 event was fired second time
// when body.innerHTML changed from false
// to server response approx. after 1 sec
return;
}

Maybe you forgot to first create a table migrations:

Also there is a very userful package Generators, which makes a lot of work for you https://github.com/JeffreyWay/Laravel-4-Generators#views
Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming
Update March 2013
Git 1.8.2 added the possibility to track branches.
"
git submodule
" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).
# add submodule to track master branch
git submodule add -b master [URL to Git repo];
# update your submodule
git submodule update --remote
If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".
Also see Vogella's tutorial on submodules for general information on submodules.
Note:
git submodule add -b . [URL to Git repo];
^^^
A special value of
.
is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.
See commit b928922727d6691a3bdc28160f93f25712c565f6:
submodule add
: If --branch
is given, record it in .gitmodules
This allows you to easily record a
submodule.<name>.branch
option in.gitmodules
when you add a new submodule. With this patch,
$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>
reduces to
$ git submodule add -b <branch> <repository> [<path>]
This means that future calls to
$ git submodule update --remote ...
will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):
A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log
within that submodule.
So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:
gitslave (that you already looked at) seems to be the best fit, including for the commit operation.
It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).
Other alternatives are detailed here.
If you do not need the serialized text to be human readable, you can use pickle
.
import pickle
s = set([1,2,3])
serialized_s = pickle.dumps(s)
print "serialized:"
print serialized_s
deserialized_s = pickle.loads(serialized_s)
print "deserialized:"
print deserialized_s
Result:
serialized:
c__builtin__
set
p0
((lp1
I1
aI2
aI3
atp2
Rp3
.
deserialized:
set([1, 2, 3])
With the desing support library v23 you can set programmatically the color and the height.
Just use for the height:
TabLayout.setSelectedTabIndicatorHeight(int height)
Here the official javadoc.
Just use for the color:
TabLayout.setSelectedTabIndicatorColor(int color)
Here the official javadoc.
Here you can find the info in the Google Tracker.
You can use display: inline-block
.
If you want to completely destroy the target, you have a couple of options. First you can remove the object from the DOM as described above...
console.log($target); // jQuery object
$target.remove(); // remove target from the DOM
console.log($target); // $target still exists
Option 1 - Then replace target with an empty jQuery object (jQuery 1.4+)
$target = $();
console.log($target); // empty jQuery object
Option 2 - Or delete the property entirely (will cause an error if you reference it elsewhere)
delete $target;
console.log($target); // error: $target is not defined
More reading: info about empty jQuery object, and info about delete
Another way to do this:
first_value = df['Btime'].values[0]
This way seems to be faster than using .iloc
:
In [1]: %timeit -n 1000 df['Btime'].values[20]
5.82 µs ± 142 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each)
In [2]: %timeit -n 1000 df['Btime'].iloc[20]
29.2 µs ± 1.28 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
Use os.environ[str(DEBUSSY)]
for both reading and writing (http://docs.python.org/library/os.html#os.environ).
As for reading, you have to parse the number from the string yourself of course.
In essence, while your SQL looks perfectly reasonable, Jet has never supported the SQL standard syntax for UPDATE
. Instead, it uses its own proprietary syntax (different again from SQL Server's proprietary UPDATE
syntax) which is very limited. Often, the only workarounds "Operation must use an updatable query" are very painful. Seriously consider switching to a more capable SQL product.
For some more details about your specific problems and some possible workarounds, see Update Query Based on Totals Query Fails.
It’s a chicken-and-egg problem. You won’t be able to do it because you need to load the assets to display the progress bar widget, by which time your page will be either fully or partially downloaded. Also, you need to know the total size of the page prior to the user requesting in order to calculate a percentage.
It’s more hassle than it’s worth.
Jon Tan has done this with his site - http://jontangerine.com/ Everything including images has been declared in ems. Everything. This is how the desired effect is achieved. Text zoom and screen zoom yield almost the exact same result.
My own humble (case sensitive) solution:
uint8_t strContains(char* string, char* toFind)
{
uint8_t slen = strlen(string);
uint8_t tFlen = strlen(toFind);
uint8_t found = 0;
if( slen >= tFlen )
{
for(uint8_t s=0, t=0; s<slen; s++)
{
do{
if( string[s] == toFind[t] )
{
if( ++found == tFlen ) return 1;
s++;
t++;
}
else { s -= found; found=0; t=0; }
}while(found);
}
return 0;
}
else return -1;
}
Results
strContains("this is my sample example", "th") // 1
strContains("this is my sample example", "sample") // 1
strContains("this is my sample example", "xam") // 1
strContains("this is my sample example", "ple") // 1
strContains("this is my sample example", "ssample") // 0
strContains("this is my sample example", "samplee") // 0
strContains("this is my sample example", "") // 0
strContains("str", "longer sentence") // -1
strContains("ssssssample", "sample") // 1
strContains("sample", "sample") // 1

As of python 3.5+:
@functools.wraps(f)
def g():
pass
Is an alias for g = functools.update_wrapper(g, f)
. It does exactly three things:
__module__
, __name__
, __qualname__
, __doc__
, and __annotations__
attributes of f
on g
. This default list is in WRAPPER_ASSIGNMENTS
, you can see it in the functools source.__dict__
of g
with all elements from f.__dict__
. (see WRAPPER_UPDATES
in the source)__wrapped__=f
attribute on g
The consequence is that g
appears as having the same name, docstring, module name, and signature than f
. The only problem is that concerning the signature this is not actually true: it is just that inspect.signature
follows wrapper chains by default. You can check it by using inspect.signature(g, follow_wrapped=False)
as explained in the doc. This has annoying consequences:
Signature.bind()
.Now there is a bit of confusion between functools.wraps
and decorators, because a very frequent use case for developing decorators is to wrap functions. But both are completely independent concepts. If you're interested in understanding the difference, I implemented helper libraries for both: decopatch to write decorators easily, and makefun to provide a signature-preserving replacement for @wraps
. Note that makefun
relies on the same proven trick than the famous decorator
library.
All of the current answers are addressing the symptom (shared memory pool exhaustion), and not the problem, which is likely not using bind variables in your sql \ JDBC queries, even when it does not seem necessary to do so. Passing queries without bind variables causes Oracle to "hard parse" the query each time, determining its plan of execution, etc.
https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::p11_question_id:528893984337
Some snippets from the above link:
"Java supports bind variables, your developers must start using prepared statements and bind inputs into it. If you want your system to ultimately scale beyond say about 3 or 4 users -- you will do this right now (fix the code). It is not something to think about, it is something you MUST do. A side effect of this - your shared pool problems will pretty much disappear. That is the root cause. "
"The way the Oracle shared pool (a very important shared memory data structure) operates is predicated on developers using bind variables."
" Bind variables are SO MASSIVELY important -- I cannot in any way shape or form OVERSTATE their importance. "
Many of these answers mention how to share the project on Git, which is easy, you just share the code on git, but one thing to take note of is that there is no apparent "project file" that the end user can double click on. Instead you have to use Import->General->Existing project and select the whole folder
$(window).keypress(function(event) {
if (!(event.which == 115 && event.ctrlKey) && !(event.which == 19)) return true;
alert("Ctrl-S pressed");
event.preventDefault();
return false;
});
Key codes can differ between browsers, so you may need to check for more than just 115.
In this approach only one statement is executed when the UPDATE is successful.
-- For each row in source
BEGIN TRAN
UPDATE target
SET <target_columns> = <source_values>
WHERE <target_expression>
IF (@@ROWCOUNT = 0)
INSERT target (<target_columns>)
VALUES (<source_values>)
COMMIT
Inaccessible logs: Security
A new event source needs to have a unique name across all logs including Security (which needs admin privilege when it's being read).
So your app will need admin privilege to create a source. But that's probably an overkill.
I wrote this powershell script to create the event source at will. Save it as *.ps1
and run it with any privilege and it will elevate itself.
# CHECK OR RUN AS ADMIN
If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{
$arguments = "& '" + $myinvocation.mycommand.definition + "'"
Start-Process powershell -Verb runAs -ArgumentList $arguments
Break
}
# CHECK FOR EXISTENCE OR CREATE
$source = "My Service Event Source";
$logname = "Application";
if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
[System.Diagnostics.EventLog]::CreateEventSource($source, $logname);
Write-Host $source -f white -nonewline; Write-Host " successfully added." -f green;
}
else
{
Write-Host $source -f white -nonewline; Write-Host " already exists.";
}
# DONE
Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');
Make sure that the value of the column is really NULL and not an empty string or 0.
You are mixing mysqli and mysql extensions, which will not work.
You need to use
$myConnection= mysqli_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysqli_select_db($myConnection, "mrmagicadam") or die ("no database");
mysqli
has many improvements over the original mysql
extension, so it is recommended that you use mysqli
.
I'm using db2 7.1 and SQuirrel. This is the only query that worked for me.

Switch to an older openssl package
brew switch openssl 1.0.2s

You need to wrap the forward slash to avoid cross browser issues or //commenting out.
str = 'this/that and/if';
var newstr = str.replace(/[/]/g, 'ForwardSlash');

please, be sure your connected to a ubuntu server, I Had the same problem but I was connected to other distro, check the AMI value in your details instance, it should be something like
AMI: ubuntu/images/ebs/ubuntu-precise-12.04-amd64-server-20130411.1
hope it helps
You have a scope problem indeed, because statement
is a local method variable defined here:
protected void createContents() {
...
Statement statement = null; // local variable
...
btnInsert.addMouseListener(new MouseAdapter() { // anonymous inner class
@Override
public void mouseDown(MouseEvent e) {
...
try {
statement.executeUpdate(query); // local variable out of scope here
} catch (SQLException e1) {
e1.printStackTrace();
}
...
});
}
When you try to access this variable inside mouseDown()
method you are trying to access a local variable from within an anonymous inner class and the scope is not enough. So it definitely must be final
(which given your code is not possible) or declared as a class member so the inner class can access this statement
variable.
Sources:
Make statement
a class member instead of a local variable:
public class A1 { // Note Java Code Convention, also class name should be meaningful
private Statement statement;
...
}
Define another final variable and use this one instead, as suggested by @HotLicks:
protected void createContents() {
...
Statement statement = null;
try {
statement = connect.createStatement();
final Statement innerStatement = statement;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
...
}
Reconsider your approach. If statement
variable won't be used until btnInsert
button is pressed then it doesn't make sense to create a connection before this actually happens. You could use all local variables like this:
btnInsert.addMouseListener(new MouseAdapter() {
@Override
public void mouseDown(MouseEvent e) {
try {
Class.forName("com.mysql.jdbc.Driver");
try (Connection connect = DriverManager.getConnection(...);
Statement statement = connect.createStatement()) {
// execute the statement here
} catch (SQLException ex) {
ex.printStackTrace();
}
} catch (ClassNotFoundException ex) {
e.printStackTrace();
}
});
I use this function to calculate cpu usage. Hope it can help you.

+ Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);
try {
Thread.sleep(360);
} catch (Exception e) {}
reader.seek(0);
load = reader.readLine();
reader.close();
toks = load.split(" +");
long idle2 = Long.parseLong(toks[4]);
long cpu2 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
+ Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);
return (float)(cpu2 - cpu1) / ((cpu2 + idle2) - (cpu1 + idle1));
} catch (IOException ex) {
ex.printStackTrace();
}
return 0;
}

You should not make an ajax call, just put the src of the img element as the url of the image.
This would be useful if you use GET instead of POST
<script type="text/javascript" >
$(document).ready( function() {
$('.div_imagetranscrits').html('<img src="get_image_probes_via_ajax.pl?id_project=xxx" />')
} );
</script>
If you want to POST to that image and do it the way you do (trying to parse the contents of the image on the client side, you could try something like this: http://en.wikipedia.org/wiki/Data_URI_scheme
You'll need to encode the data
to base64, then you could put data:[<MIME-type>][;charset=<encoding>][;base64],<data>
into the img src
as example:
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot img" />
To encode to base64:
Use the following function
window.scrollTo(xpos, ypos)
Here xpos is Required. The coordinate to scroll to, along the x-axis (horizontal), in pixels
ypos is also Required. The coordinate to scroll to, along the y-axis (vertical), in pixels
There should be three pages here:
I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.
I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.
You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST
submission on step 1 (and 2 if applicable).
Can add disable like below and can get data on submit. something like this .. DEMO
Html
<input type="hidden" name="email" value="email" />
<input type="text" id="dis" class="disable" value="email" name="email" >
JS
$("#dis").attr('disabled','disabled');
CSS
.disable { opacity : .35; background-color:lightgray; border:1px solid gray;}
Your using
declaration is in game.cpp
, not game.h
where you actually declare string variables. You intended to put using namespace std;
into the header, above the lines that use string
, which would let those lines find the string
type defined in the std
namespace.
As others have pointed out, this is not good practice in headers -- everyone who includes that header will also involuntarily hit the using
line and import std
into their namespace; the right solution is to change those lines to use std::string
instead
I found an answer which worked for me and can be found in the following link:
I wrote a simple function to check for a insensitive value in an array the code is below.
function:
function in_array_insensitive($needle, $haystack) {
$needle = strtolower($needle);
foreach($haystack as $k => $v) {
$haystack[$k] = strtolower($v);
}
return in_array($needle, $haystack);
}
how to use:
$array = array('one', 'two', 'three', 'four');
var_dump(in_array_insensitive('fOUr', $array));
So to make your expression work, changing &&
for -a
will do the trick.
It is correct like this:
if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
then ....
or like
if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
then ....
or even
if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
then ....
You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.
The existing JSON replacements where too much for me, so I wrote my own function. This seems to work, but I might have missed several edge cases (that don't occur in my project). And will probably not work for any pre-existing objects, only for self-made data.
function simpleJSONstringify(obj) {
var prop, str, val,
isArray = obj instanceof Array;
if (typeof obj !== "object") return false;
str = isArray ? "[" : "{";
function quote(str) {
if (typeof str !== "string") str = str.toString();
return str.match(/^\".*\"$/) ? str : '"' + str.replace(/"/g, '\\"') + '"'
}
for (prop in obj) {
if (!isArray) {
// quote property
str += quote(prop) + ": ";
}
// quote value
val = obj[prop];
str += typeof val === "object" ? simpleJSONstringify(val) : quote(val);
str += ", ";
}
// Remove last colon, close bracket
str = str.substr(0, str.length - 2) + ( isArray ? "]" : "}" );
return str;
}
Note: The solution here needs to be done at application design stage. It would be difficult to engineer this in later.
Use a hidden field to pass around the session identifier.
For this to work each page must include a form:
<form method="post" action="/handler">
<input type="hidden" name="sessionId" value="123456890123456890ABCDEF01" />
<input type="hidden" name="action" value="" />
</form>
Every action on your side, including navigation, POSTs the form back (setting the action
as appropriate). For "unsafe" requests, you could include another parameter, say containing a JSON value of the data to be submitted:
<input type="hidden" name="action" value="completeCheckout" />
<input type="hidden" name="data" value='{ "cardNumber" : "4111111111111111", ... ' />
As there are no cookies, each tab will be independent and will have no knowledge of other sessions in the same browser.
Lots of advantages, particularly when it comes to security:

$unionWith
combines records from the given collection within documents already in the aggregation pipeline. After the 2 union stages, we thus have all users, books and movies records within the pipeline.
We then $group
records by $user
and accumulate items using the $accumulator
operator allowing custom accumulations of documents as they get grouped:
accumulateArgs
.init
defines the state that will be accumulated as we group elements.accumulate
function allows performing a custom action with a record being grouped in order to build the accumulated state. For instance, if the item being grouped has the book
field defined, then we update the books
part of the state.merge
is used to merge two internal states. It's only used for aggregations running on sharded clusters or when the operation exceeds memory limits.This is what you need in the CSS:
html, body {
height: 100%;
width: 100%;
margin: 0;

You info.plist must looks like this:
If the object is actually a Boolean
instance, then just cast it:
boolean di = (Boolean) someObject;
The explicit cast will do the conversion to Boolean
, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:
boolean di = ((Boolean) someObject).booleanValue();
If someObject
doesn't refer to a Boolean value though, what do you want the code to do?
Customizing the background of a table view cell eventually becomes and "all or nothing" approach. It's very difficult to change the color or image used for the background of a content cell in a way that doesn't look strange.
The reason is that the cell actually spans the width of the view. The rounded corners are just part of its drawing style and the content view sits in this area.
If you change the color of the content cell you will end up with white bits visible at the corners. If you change the color of the entire cell, you will have a block of color spanning the width of the view.
You can definitely customize a cell, but it's not quite as easy as you may think at first.

Here is a sample query for a table having a foreign key relationship to the same table with a query parameter.
SET @x = -1;
SELECT id, categoryName
FROM Catergory WHERE IF(@x > 0,category_ParentId = @x,category_ParentId IS NOT NULL);
@x
can be changed.
If you wish to have a progress bar without adding some code PACE can be an awesome tool for you.
Just include pace.js and a CSS theme of your choice, and you get a beautiful progress indicator for your page load and AJAX navigation. Best thing with PACE is the auto detection of progress.
It contains various themes and color schemes as well.
Worth a try.
A violation like that means that there's something seriously wrong with the code, and it's unreliable. I can see that a program might want to try to save the user's data in a way that one hopes won't write over previous data, in the hope that the user's data isn't already corrupted, but there is by definition no standard method of dealing with undefined behavior.
Use -o
, which means "or":
find Documents \( -name "*.py" -o -name "*.html" \)
You'd need to build that command line programmatically, which isn't that easy.
Are you using bash (or Cygwin on Windows)? If you are, you should be able to do this:
ls **/*.py **/*.html
which might be easier to build programmatically.
try this...
$('.testimonial').each(function(){

Removing the '^' did it for me. I'm looking at a varchar field and when I included the ^ it excluded all of my non-numerics which is exactly what I didn't want. So, by removing ^ I only got non-numeric values back.
Sometimes passing parameters in the main method causes this problem eg. public static void main(String[] args,int a)
. If you declare the variable outside the main method, it might help :)
i was trying trying to GRANT read-only privileges to a particular table to a user called walters-ro. So when i ran the sql command # GRANT SELECT ON table_name TO walters-ro; --- i got the following error..`syntax error at or near “-”
The solution to this was basically putting the user_name into double quotes since there is a dash(-) between the name.
# GRANT SELECT ON table_name TO "walters-ro";
That solved the problem.
The reason your URL is being rewritten to file///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf
is because you specified http://file://
The http://
at the beginning is the protocol being used, and your browser is stripping out the second colon (:) because it is invalid.
Note
If you link to something like
<a href="file:///K:/yourfile.pdf">yourfile.pdf</a>
The above represents a link to a file called k:/yourfile.pdf
on the k: drive on the machine on which you are viewing the URL.
You can do this, for example the below creates a link to C:\temp\test.pdf
<a href="file:///C:/Temp/test.pdf">test.pdf</a>
By specifying file:// you are indicating that this is a local resource. This resource is NOT on the internet.
Most people do not have a K:/ drive.
But, if this is what you are trying to achieve, that's fine, but this is not how a "typical" link on a web page works, and you shouldn't being doing this unless everyone who is going to access your link has access to the (same?) K:/drive (this might be the case with a shared network drive).
You could try
<a href="file:///K:/AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
Note that http://file:///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf
is a malformed
Quotes, but I prefer them on the just the value:
url: "http://www.example.com/"
Putting them across the whole line looks like it might cause problems.
Once I found what format it was looking for in the connection string, it worked just fine like this with Oracle.ManagedDataAccess. Without having to mess around with anything separately.

If you have upgraded your PHP version, make sure that the old PHP version configuration in your .htaccess has been deleted. For more info, check this https://www.hostgator.com/help/article/php-configuration-plugin
Try this:
// MockHttpSession Setup
var session = new MockHttpSession();
// MockHttpRequest Setup - mock AJAX request
var httpRequest = new Mock<HttpRequestBase>();
// Setup this part of the HTTP request for AJAX calls
httpRequest.Setup(req => req["X-Requested-With"]).Returns("XMLHttpRequest");
// MockHttpContextBase Setup - mock request, cache, and session
var httpContext = new Mock<HttpContextBase>();
httpContext.Setup(ctx => ctx.Request).Returns(httpRequest.Object);
httpContext.Setup(ctx => ctx.Cache).Returns(HttpRuntime.Cache);
httpContext.Setup(ctx => ctx.Session).Returns(session);
// MockHttpContext for cache
var contextRequest = new HttpRequest("", "http://localhost/", "");
var contextResponse = new HttpResponse(new StringWriter());
HttpContext.Current = new HttpContext(contextRequest, contextResponse);
// MockControllerContext Setup
var context = new Mock<ControllerContext>();
context.Setup(ctx => ctx.HttpContext).Returns(httpContext.Object);
//TODO: Create new controller here
// Set controller's ControllerContext to context.Object
And Add the class:
public class MockHttpSession : HttpSessionStateBase
{
Dictionary<string, object> _sessionDictionary = new Dictionary<string, object>();
public override object this[string name]
{
get
{
return _sessionDictionary.ContainsKey(name) ? _sessionDictionary[name] : null;
}
set
{
_sessionDictionary[name] = value;
}
}
public override void Abandon()
{
var keys = new List<string>();
foreach (var kvp in _sessionDictionary)
{
keys.Add(kvp.Key);
}
foreach (var key in keys)
{
_sessionDictionary.Remove(key);
}
}
public override void Clear()
{
var keys = new List<string>();
foreach (var kvp in _sessionDictionary)
{
keys.Add(kvp.Key);
}
foreach(var key in keys)
{
_sessionDictionary.Remove(key);
}
}
}
This will allow you to test with both session and cache.

I have tried all solution. The -lopencv_core -lopencv_imgproc -lopencv_highgui
in comments solved my problem. And know my command line looks like this in geany:
g++ -lopencv_core -lopencv_imgproc -lopencv_highgui -o "%e" "%f"
When I build:
g++ -lopencv_core -lopencv_imgproc -lopencv_highgui -o "opencv" "opencv.cpp" (in directory: /home/fedora/Desktop/Implementations)
The headers are:
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
Another way to validate is like this.
var $radio = $('input:radio[name="nameRadioButton"]');
$radio.addClass("validate[required]");
I hope my example will help you
Give this a shot:
has_many :jobs, foreign_key: "user_id", class_name: "Task"
Note, that :as
is used for polymorphic associations.
While some of these solutions may work, none of them follow best practices. Many assign global variables and you may find yourself making calls to multiple parent variables or functions, leading to a cluttered, vulnerable namespace.
To avoid this, use a module pattern. In the parent window:
var myThing = {
var i = 0;
myFunction : function () {
// do something
}
};
var newThing = Object.create(myThing);
Then, in the iframe:
function myIframeFunction () {
parent.myThing.myFunction();
alert(parent.myThing.i);
};
This is similar to patterns described in the Inheritance chapter of Crockford's seminal text, "Javascript: The Good Parts." You can also learn more at w3's page for Javascript's best practices. https://www.w3.org/wiki/JavaScript_best_practices#Avoid_globals
Did you override equals and hashCode in the Block class?
EDIT:
I assumed you mean it doesn't work at runtime... did you mean that or at compile time? If compile time what is the error message? If it crashes at runtime what is the stack trace? If it compiles and runs but doesn't work right then the equals and hashCode are the likely issue.

Use the following to inject Hibernate with Spring in your unit tests:
@Bean
public LocalSessionFactoryBean getLocalSessionFactoryBean() {
LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();
localSessionFactoryBean.setConfigLocation(new ClassPathResource("hibernate.cfg.xml"));
localSessionFactoryBean.setPackagesToScan("com.example.yourpackage.model");
return localSessionFactoryBean;
}
If you don't have the hibernate.cfg.xml
present in your src/test/resources
folder it will automatically fall back to the one in your src/main/resources
folder.
This question is some years old but i came via a duplicate to it. I want to suggest a more general solution too. If you know you always have a fixed number of ancestors you can use some self joins as already suggested in the answers. If you want a generic approach go on reading.
What you need here is called Quotient in relational Algebra. The Quotient is more or less the reversal of the Cartesian Product (or Cross Join in SQL).
Let's say your ancestor set A
is (i use a table notation here, i think this is better for understanding)
ancestry
-----------
'England'
'France'
'Germany'
and your user set U
is
user_id
--------
1
2
3
The cartesian product C=AxU
is then:
user_id | ancestry
---------+-----------
1 | 'England'
1 | 'France'
1 | 'Germany'
2 | 'England'
2 | 'France'
2 | 'Germany'
3 | 'England'
3 | 'France'
3 | 'Germany'
If you calculate the set quotient U=C/A
then you get
user_id
--------
1
2
3
If you redo the cartesian product UXA
you will get C
again. But note that for a set T
, (T/A)xA
will not necessarily reproduce T
. For example, if T
is
user_id | ancestry
---------+-----------
1 | 'England'
1 | 'France'
1 | 'Germany'
2 | 'England'
2 | 'France'
then (T/A)
is
user_id
--------
1
(T/A)xA
will then be
user_id | ancestry
---------+------------
1 | 'England'
1 | 'France'
1 | 'Germany'
Note that the records for user_id=2
have been eliminated by the Quotient and Cartesian Product operations.
Your question is: Which user_id has ancestors from all countries in your ancestor set? In other words you want U=T/A
where T
is your original set (or your table).
To implement the quotient in SQL you have to do 4 steps:
So let's do it step by step. I will use TSQL syntax (Microsoft SQL server) but it should easily be adaptable to other DBMS. As a name for the table (user_id, ancestry)
i choose ancestor
CREATE TABLE ancestry_set (ancestry nvarchar(25))
INSERT INTO ancestry_set (ancestry) VALUES ('England')
INSERT INTO ancestry_set (ancestry) VALUES ('France')
INSERT INTO ancestry_set (ancestry) VALUES ('Germany')
CREATE TABLE ancestor ([user_id] int, ancestry nvarchar(25))
INSERT INTO ancestor ([user_id],ancestry) VALUES (1,'England')
INSERT INTO ancestor ([user_id],ancestry) VALUES(1,'Ireland')
INSERT INTO ancestor ([user_id],ancestry) VALUES(2,'France')
INSERT INTO ancestor ([user_id],ancestry) VALUES(3,'Germany')
INSERT INTO ancestor ([user_id],ancestry) VALUES(3,'Poland')
INSERT INTO ancestor ([user_id],ancestry) VALUES(4,'England')
INSERT INTO ancestor ([user_id],ancestry) VALUES(4,'France')
INSERT INTO ancestor ([user_id],ancestry) VALUES(4,'Germany')
INSERT INTO ancestor ([user_id],ancestry) VALUES(5,'France')
INSERT INTO ancestor ([user_id],ancestry) VALUES(5,'Germany')
1) Create the Cartesian Product of your ancestry set and the set of all user_ids.
SELECT a.[user_id],s.ancestry
FROM ancestor a, ancestry_set s
GROUP BY a.[user_id],s.ancestry
2) Find all records in the Cartesian Product which have no partner in the original set (Left Join) and
3) Extract the user_ids from the resultset of 2)
SELECT DISTINCT cp.[user_id]
FROM (SELECT a.[user_id],s.ancestry
FROM ancestor a, ancestry_set s
GROUP BY a.[user_id],s.ancestry) cp
LEFT JOIN ancestor a ON cp.[user_id]=a.[user_id] AND cp.ancestry=a.ancestry
WHERE a.[user_id] is null
4) Return all user_ids from the original set which are not included in the result set of 3)
SELECT DISTINCT [user_id]
FROM ancestor
WHERE [user_id] NOT IN (
SELECT DISTINCT cp.[user_id]
FROM (SELECT a.[user_id],s.ancestry
FROM ancestor a, ancestry_set s
GROUP BY a.[user_id],s.ancestry) cp
LEFT JOIN ancestor a ON cp.[user_id]=a.[user_id] AND cp.ancestry=a.ancestry
WHERE a.[user_id] is null
)
If you want to match anything after a word stop an not only at the start of the line you may use : \bstop.*\b
- word followed by line
Or if you want to match the word in the string use \bstop[a-zA-Z]*
- only the words starting with stop
Or the start of lines with stop ^stop[a-zA-Z]*
for the word only - first word only
The whole line ^stop.*
- first line of the string only
And if you want to match every string starting with stop including newlines use : /^stop.*/s
- multiline string starting with stop

window.pack();

Much like setState in Class components created by extending React.Component
or React.PureComponent
, the state update using the updater provided by useState
hook is also asynchronous, and will not be reflected immediately.
Also, the main issue here is not just the asynchronous nature but the fact that state values are used by functions based on their current closures, and state updates will reflect in the next re-render by which the existing closures are not affected, but new ones are created. Now in the current state, the values within hooks are obtained by existing closures, and when a re-render happens, the closures are updated based on whether the function is recreated again or not.
Even if you add a setTimeout
the function, though the timeout will run after some time by which the re-render would have happened, the setTimeout
will still use the value from its previous closure and not the updated one.
setMovies(result);
console.log(movies) // movies here will not be updated
If you want to perform an action on state update, you need to use the useEffect hook, much like using componentDidUpdate
in class components since the setter returned by useState doesn't have a callback pattern
useEffect(() => {
// action on update of movies
}, [movies]);
As far as the syntax to update state is concerned, setMovies(result)
will replace the previous movies
value in the state with those available from the async request.
However, if you want to merge the response with the previously existing values, you must use the callback syntax of state updation along with the correct use of spread syntax like
setMovies(prevMovies => ([...prevMovies, ...result]));

the fast way if the property is not in the model :
document.set( key,value, { strict: false });
Note that the performance of Enum.Parse()
is awful, because it is implemented via reflection. (The same is true of Enum.ToString
, which goes the other way.)
If you need to convert strings to Enums in performance-sensitive code, your best bet is to create a Dictionary<String,YourEnum>
at startup and use that to do your conversions.

In my case, it was an accidental double escaping.
