You can not ask for instance during configuration phase - you can ask only for providers.
var app = angular.module('modx', []);
// configure stuff
app.config(function($routeProvider, $locationProvider) {
// you can inject any provider here
});
// run blocks
app.run(function($rootScope) {
// you can inject any instance here
});
See http://docs.angularjs.org/guide/module for more info.
ImageArtist is a pure gd wrapper authored by me, this enables you to do complex image manipulations insanely easy, for your question solution can be done using very few steps using this powerful library.
here is a sample code.
$img1 = new Image("./cover.jpg");
$img2 = new Image("./box.png");
$img2->merge($img1,9,9);
$img2->save("./merged.png",IMAGETYPE_PNG);
This is how my result looks like.

Works for jekyll or more specifically kramdown, which is a superset of markdown, as part of Jekyll's (default) configuration. But not for plain markdown. ^_^
What files are you importing into the files getting the R error?
My understanding of the R file are that they are automatically generated reference lists to all attributes within the Android app. Therefore, you can't change it yourself.
Are you using Eclipse to build this project? Were the older projects getting these errors made before updating Eclipse? What are the references that are getting errors?
Check to make sure that you've not imported another R file from other copied code in another app.
Slightly off topic, but for those of you that want to modify the built-in colors of the Dark/Light themes you can use this little tool I wrote for Visual Studio 2012.

Hope this helps!
This is what I did for the instagram API. converted timestamp with date method by multiplying by 1000. and then added all entity individually like (year, months, etc)
created the custom month list name and mapped with getMonth()
method which returns the index of the month.
convertStampDate(unixtimestamp){
// Unixtimestamp
// Months array
var months_arr = ['January','February','March','April','May','June','July','August','September','October','November','December'];
// Convert timestamp to milliseconds
var date = new Date(unixtimestamp*1000);
// Year
var year = date.getFullYear();
// Month
var month = months_arr[date.getMonth()];
// Day
var day = date.getDate();
// Hours
var hours = date.getHours();
// Minutes
var minutes = "0" + date.getMinutes();
// Seconds
var seconds = "0" + date.getSeconds();
// Display date time in MM-dd-yyyy h:m:s format
var fulldate = month+' '+day+'-'+year+' '+hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);
// filtered fate
var convdataTime = month+' '+day;
return convdataTime;
}
Call with stamp argument
convertStampDate('1382086394000')
and thats it.
On the Mac you can store the passphrase for your private ssh key in your Keychain, which makes the use of it transparent. If you're logged in, it is available, when you are logged out your root user cannot use it. Removing the passphrase is a bad idea because anyone with the file can use it.
ssh-keygen -K

You could use apache common library's StringUtils to do this.

You could use AJAX to send a POST request if you don't want forms.
Using jquery $.post method it is pretty simple:
$.post('/foo.php', { key1: 'value1', key2: 'value2' }, function(result) {
alert('successfully posted key1=value1&key2=value2 to foo.php');
});
There is a package random_word could implement this request very conveniently:
$ pip install random-word
from random_word import RandomWords
r = RandomWords()
# Return a single random word
r.get_random_word()
# Return list of Random words
r.get_random_words()
# Return Word of the day
r.word_of_the_day()
The original variables you listed can be declared and assigned to the same value in a short line of code using destructuring assignment. The keywords let
, const
, and var
can all be used for this type of assignment.
let [moveUp, moveDown, moveLeft, moveRight, mouseDown, touchDown] = Array(6).fill(false);
Use Python:
#!/bin/bash
# home/victoria/test.sh
START=$(date +"%s") ## seconds since Epoch
for i in $(seq 1 10)
do
sleep 1.5
END=$(date +"%s") ## integer
TIME=$((END - START)) ## integer
AVG_TIME=$(python -c "print(float($TIME/$i))") ## int to float
printf 'i: %i | elapsed time: %0.1f sec | avg. time: %0.3f\n' $i $TIME $AVG_TIME
((i++)) ## increment $i
done
Output
$ ./test.sh
i: 1 | elapsed time: 1.0 sec | avg. time: 1.000
i: 2 | elapsed time: 3.0 sec | avg. time: 1.500
i: 3 | elapsed time: 5.0 sec | avg. time: 1.667
i: 4 | elapsed time: 6.0 sec | avg. time: 1.500
i: 5 | elapsed time: 8.0 sec | avg. time: 1.600

You can remove the duplicated values and keep the list order of insertion with one line of code, Python 3.8.2
mylist = ['b', 'b', 'a', 'd', 'd', 'c'] results = list({value:"" for value in mylist}) print(results) >>> ['b', 'a', 'd', 'c'] results = list(dict.fromkeys(mylist)) print(results) >>> ['b', 'a', 'd', 'c']

There's a relatively new way of doing transparency, it's called HEXA (HEX + Alpha). It takes in 8 digits instead of 6. The last pair is Alpha. So the pattern of pairs is #RRGGBBAA. Having 4 digits also works: #RGBA
I am not sure about its browser support for now but, you can check the DRAFT Docs for more information.
§ 4.2. The RGB hexadecimal notations: #RRGGBB
The syntax of a
<hex-color>
is a<hash-token>
token whose value consists of 3, 4, 6, or 8 hexadecimal digits. In other words, a hex color is written as a hash character, "#", followed by some number of digits0-9
or lettersa-f
(the case of the letters doesn’t matter -#00ff00
is identical to#00FF00
).8 digits
The first 6 digits are interpreted identically to the 6-digit notation. The last pair of digits, interpreted as a hexadecimal number, specifies the alpha channel of the color, where
00
represents a fully transparent color andff
represent a fully opaque color.Example 3
In other words,#0000ffcc
represents the same color asrgba(0, 0, 100%, 80%)
(a slightly-transparent blue).4 digits
This is a shorter variant of the 8-digit notation, "expanded" in the same way as the 3-digit notation is. The first digit, interpreted as a hexadecimal number, specifies the red channel of the color, where
0
represents the minimum value andf
represents the maximum. The next three digits represent the green, blue, and alpha channels, respectively.
For the most part, Chrome and Firefox have started supporting this:
1.) Never use MESH COLLIDER. Use combination of box and capsule collider.
2.) Check constraints in RigidBody. If you tick Freeze Position X than it will pass through the object on the X axis. (Same for y axis).
If you only need the first row from each group we can do with drop_duplicates
, Notice the function default method keep='first'
.
df.drop_duplicates('id')
Out[1027]:
id value
0 1 first
3 2 first
5 3 first
9 4 second
11 5 first
12 6 first
15 7 fourth
At first glance your original attempt seems pretty close. I'm assuming that clockDate is a DateTime fields so try this:
IF (NOT EXISTS(SELECT * FROM Clock WHERE cast(clockDate as date) = '08/10/2012')
AND userName = 'test')
BEGIN
INSERT INTO Clock(clockDate, userName, breakOut)
VALUES(GetDate(), 'test', GetDate())
END
ELSE
BEGIN
UPDATE Clock
SET breakOut = GetDate()
WHERE Cast(clockDate AS Date) = '08/10/2012' AND userName = 'test'
END
Note that getdate gives you the current date. If you are trying to compare to a date (without the time) you need to cast or the time element will cause the compare to fail.
If clockDate is NOT datetime field (just date), then the SQL engine will do it for you - no need to cast on a set/insert statement.
IF (NOT EXISTS(SELECT * FROM Clock WHERE clockDate = '08/10/2012')
AND userName = 'test')
BEGIN
INSERT INTO Clock(clockDate, userName, breakOut)
VALUES(GetDate(), 'test', GetDate())
END
ELSE
BEGIN
UPDATE Clock
SET breakOut = GetDate()
WHERE clockDate = '08/10/2012' AND userName = 'test'
END
As others have pointed out, the merge statement is another way to tackle this same logic. However, in some cases, especially with large data sets, the merge statement can be prohibitively slow, causing a lot of tran log activity. So knowing how to logic it out as shown above is still a valid technique.
There's no way of calling (eg) printf without knowing how many arguments you're passing to it, unless you want to get into naughty and non-portable tricks.
The generally used solution is to always provide an alternate form of vararg functions, so printf
has vprintf
which takes a va_list
in place of the ...
. The ...
versions are just wrappers around the va_list
versions.

Adding to the answer given by @insomniac. You can create a Map
to put the parameter for RequestBody
including image.
Code for Interface
public interface ApiInterface {
@Multipart
@POST("/api/Accounts/editaccount")
Call<User> editUser (@Header("Authorization") String authorization, @PartMap Map<String, RequestBody> map);
}
Code for Java class
File file = new File(imageUri.getPath());
RequestBody fbody = RequestBody.create(MediaType.parse("image/*"), file);
RequestBody name = RequestBody.create(MediaType.parse("text/plain"), firstNameField.getText().toString());
RequestBody id = RequestBody.create(MediaType.parse("text/plain"), AZUtils.getUserId(this));
Map<String, RequestBody> map = new HashMap<>();
map.put("file\"; filename=\"pp.png\" ", fbody);
map.put("FirstName", name);
map.put("Id", id);
Call<User> call = client.editUser(AZUtils.getToken(this), map);
call.enqueue(new Callback<User>() {
@Override
public void onResponse(retrofit.Response<User> response, Retrofit retrofit)
{
AZUtils.printObject(response.body());
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
}
});
Access-Engine does not support
SELECT count(DISTINCT....) FROM ...
You have to do it like this:
SELECT count(*)
FROM
(SELECT DISTINCT Name FROM table1)
Its a little workaround... you're counting a DISTINCT selection.
I have noticed these differences:
A. We iterate the list in different way, foreach can be used for IEnumerable and while loop for IEnumerator.
B. IEnumerator can remember the current index when we pass from one method to another (it start working with current index) but IEnumerable can't remember the index and it reset the index to beginning. More in this video https://www.youtube.com/watch?v=jd3yUjGc9M0
SQL Server uses the TCP port 1433. This is probably blocked either by the VPN tunnel or by a firewall on the server.
I have this method for deserializing an XML and converting the type:
public <T> Object deserialize(String xml, Class objClass ,TypeReference<T> typeReference ) throws IOException {
XmlMapper xmlMapper = new XmlMapper();
Object obj = xmlMapper.readValue(xml,objClass);
return xmlMapper.convertValue(obj,typeReference );
}
and this is the call:
List<POJO> pojos = (List<POJO>) MyUtilClass.deserialize(xml, ArrayList.class,new TypeReference< List< POJO >>(){ });
The pattern you want is something like (see it on rubular.com):
^[a-zA-Z0-9_.-]*$
Explanation:
^
is the beginning of the line anchor$
is the end of the line anchor[...]
is a character class definition*
is "zero-or-more" repetitionNote that the literal dash -
is the last character in the character class definition, otherwise it has a different meaning (i.e. range). The .
also has a different meaning outside character class definitions, but inside, it's just a literal .
Here's a snippet to show how you can use this pattern:
<?php
$arr = array(
'screen123.css',
'screen-new-file.css',
'screen_new.js',
'screen new file.css'
);
foreach ($arr as $s) {
if (preg_match('/^[\w.-]*$/', $s)) {
print "$s is a match\n";
} else {
print "$s is NO match!!!\n";
};
}
?>
The above prints (as seen on ideone.com):
screen123.css is a match
screen-new-file.css is a match
screen_new.js is a match
screen new file.css is NO match!!!
Note that the pattern is slightly different, using \w
instead. This is the character class for "word character".
This seems to follow your specification, but note that this will match things like .....
, etc, which may or may not be what you desire. If you can be more specific what pattern you want to match, the regex will be slightly more complicated.
The above regex also matches the empty string. If you need at least one character, then use +
(one-or-more) instead of *
(zero-or-more) for repetition.
In any case, you can further clarify your specification (always helps when asking regex question), but hopefully you can also learn how to write the pattern yourself given the above information.
All answers are great, and I encourage to use those methods with this one to improve build speed.
After release of android 2.2 on September 2016, Android released experimental build cache feature to speed up gradle
build performance, which is now official from Android Studio 2.3 Canary. (Official Release note)
It introduces a new build cache feature, which is enable by default, can speed up build times (including full builds, incremental builds, and instant run) by storing and reusing files/directories that were created in previous builds of the same or different Android project.
How to use:
Add following line in your gradle.properties
file
android.enableBuildCache = true
# Set to true or false to enable or disable the build cache. If this parameter is not set, the build cache is enable by default.
Clean the cache:
There is a new Gradle task called cleanBuildCache
for you to more easily clean the build cache. You can use it by typing the following in your terminal:
./gradlew cleanBuildCache
OR You can clean the cache for Android studio 2.2 by deleting all the files store at location
C:\Users\<username>\.android\build-cache
That is not possible with a normal query since the in

exec('select * from DBTable where id IN ' + @myList)

Perhaps appending DateTime.Now.Ticks
instead, is a tiny bit faster since you won't be creating 3 strings and the ticks value will always be unique also.
I don't fully understand what was the problem with the "update current of cursor" but it is solved by using the fetch statement twice for the inner cursor:
FETCH NEXT FROM INNER_CURSOR
WHILE (@@FETCH_STATUS <> -1)
BEGIN
UPDATE CONTACTS
SET INDEX_NO = @COUNTER
WHERE CURRENT OF INNER_CURSOR
SET @COUNTER = @COUNTER + 1
FETCH NEXT FROM INNER_CURSOR
FETCH NEXT FROM INNER_CURSOR
END
Just use order allow,deny
instead and remove the deny from all
line.
if you're using NSNotificationCenter for updating your view, don't forget to send it from the main thread by calling dispatch_async
:
dispatch_async(dispatch_get_main_queue(),^{
[[NSNotificationCenter defaultCenter] postNotificationName:@"my_notification" object:nil];
});
The connector section has the parameter
maxPostSize
The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).
Another Limit is:
maxHttpHeaderSize The maximum size of the request and response HTTP header, specified in bytes. If not specified, this attribute is set to 4096 (4 KB).

Is JSTL's join()
, what you searched for?
<c:set var="myVar" value="${fn:join(myParams.items, ' ')}" />
The compiler looks for each symbol being used in the current translation unit is previously declared or not in the current unit. It is just a matter of style providing all method signatures at the beginning of a source file while definitions are provided later. The significant use of it is when you use a pointer to a class as member variable of another class.
//foo.h
class bar; // This is useful
class foo
{
bar* obj; // Pointer or even a reference.
};
// foo.cpp
#include "bar.h"
#include "foo.h"
So, use forward-declarations in classes when ever possible. If your program just has functions( with ho header files), then providing prototypes at the beginning is just a matter of style. This would be anyhow the case had if the header file was present in a normal program with header that has only functions.
Actually I am preferring to use NEW_BROKER
,it is working fine on all cases:
ALTER DATABASE [dbname] SET NEW_BROKER WITH ROLLBACK IMMEDIATE;
A simple (but not very fast) method to calculate the square root of X:
squareroot(x)
if x<0 then Error
a = 1
b = x
while (abs(a-b)>ErrorMargin)
a = (a+b)/2
b = x/a
endwhile
return a;
Example: squareroot(70000)
a b
1 70000
35001 2
17502 4
8753 8
4381 16
2199 32
1116 63
590 119
355 197
276 254
265 264
As you can see it defines an upper and a lower boundary for the square root and narrows the boundary until its size is acceptable.
There are more efficient methods but this one illustrates the process and is easy to understand.
Just beware to set the Errormargin to 1 if using integers else you have an endless loop.
Another reason to use merge is when using custom viewgroups in ListViews or GridViews. Instead of using the viewHolder pattern in a list adapter, you can use a custom view. The custom view would inflate an xml whose root is a merge tag. Code for adapter:
public class GridViewAdapter extends BaseAdapter {
// ... typical Adapter class methods
@Override
public View getView(int position, View convertView, ViewGroup parent) {
WallpaperView wallpaperView;
if (convertView == null)
wallpaperView = new WallpaperView(activity);
else
wallpaperView = (WallpaperView) convertView;
wallpaperView.loadWallpaper(wallpapers.get(position), imageWidth);
return wallpaperView;
}
}
here is the custom viewgroup:
public class WallpaperView extends RelativeLayout {
public WallpaperView(Context context) {
super(context);
init(context);
}
// ... typical constructors
private void init(Context context) {
View.inflate(context, R.layout.wallpaper_item, this);
imageLoader = AppController.getInstance().getImageLoader();
imagePlaceHolder = (ImageView) findViewById(R.id.imgLoader2);
thumbnail = (NetworkImageView) findViewById(R.id.thumbnail2);
thumbnail.setScaleType(ImageView.ScaleType.CENTER_CROP);
}
public void loadWallpaper(Wallpaper wallpaper, int imageWidth) {
// ...some logic that sets the views
}
}
and here is the XML:
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:id="@+id/imgLoader"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_centerInParent="true"
android:src="@drawable/ico_loader" />
<com.android.volley.toolbox.NetworkImageView
android:id="@+id/thumbnail"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</merge>
DISCLAIMER: This solution is not 100% accurate in terms of determining the minimal width.
I was also figuring out how to measure text on a canvas. After reading the great post from mice i had some problems on how to measure multiline text. There is no obvious way from these contributions but after some research i cam across the StaticLayout class. It allows you to measure multiline text (text with "\n") and configure much more properties of your text via the associated Paint.
Here is a snippet showing how to measure multiline text:
private StaticLayout measure( TextPaint textPaint, String text, Integer wrapWidth ) {
int boundedWidth = Integer.MAX_VALUE;
if (wrapWidth != null && wrapWidth > 0 ) {
boundedWidth = wrapWidth;
}
StaticLayout layout = new StaticLayout( text, textPaint, boundedWidth, Alignment.ALIGN_NORMAL, 1.0f, 0.0f, false );
return layout;
}
The wrapwitdh is able to determin if you want to limit your multiline text to a certain width.
Since the StaticLayout.getWidth() only returns this boundedWidth you have to take another step to get the maximum width required by your multiline text. You are able to determine each lines width and the max width is the highest line width of course:
private float getMaxLineWidth( StaticLayout layout ) {
float maxLine = 0.0f;
int lineCount = layout.getLineCount();
for( int i = 0; i < lineCount; i++ ) {
if( layout.getLineWidth( i ) > maxLine ) {
maxLine = layout.getLineWidth( i );
}
}
return maxLine;
}
Use a Scanner
and pass in the delimiter and the original string:
result = new Scanner(result).useDelimiter("\n").next();
This solution works aswell. If there is no Facebook installed, it just runs the normal share-dialog. If there is and you are not logged in, it goes to the login screen. If you are logged in, it will open the share dialog and put in the "Share url" from the Intent Extra.
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "Share url");
intent.setType("text/plain");
List<ResolveInfo> matches = getMainFragmentActivity().getPackageManager().queryIntentActivities(intent, 0);
for (ResolveInfo info : matches) {
if (info.activityInfo.packageName.toLowerCase().contains("facebook")) {
intent.setPackage(info.activityInfo.packageName);
}
}
startActivity(intent);
You can use newer OpenCV python interface (if I'm not mistaken it is available since OpenCV 2.2). It natively uses numpy arrays:
import cv2
im = cv2.imread("abc.tiff",mode='RGB')
print type(im)
result:
<type 'numpy.ndarray'>
By specifying the column as VARCHAR(500)
you've set an explicit 500 character limit. You might not have done this yourself explicitly, but Django has done it for you somewhere. Telling you where is hard when you haven't shown your model, the full error text, or the query that produced the error.
If you don't want one, use an unqualified VARCHAR
, or use the TEXT
type.
varchar
and text
are limited in length only by the system limits on column size - about 1GB - and by your memory. However, adding a length-qualifier to varchar
sets a smaller limit manually. All of the following are largely equivalent:
column_name VARCHAR(500)
column_name VARCHAR CHECK (length(column_name) <= 500)
column_name TEXT CHECK (length(column_name) <= 500)
The only differences are in how database metadata is reported and which SQLSTATE is raised when the constraint is violated.
The length constraint is not generally obeyed in prepared statement parameters, function calls, etc, as shown:
regress=> \x
Expanded display is on.
regress=> PREPARE t2(varchar(500)) AS SELECT $1;
PREPARE
regress=> EXECUTE t2( repeat('x',601) );
-[ RECORD 1 ]-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
?column? | xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
and in explicit casts it result in truncation:
regress=> SELECT repeat('x',501)::varchar(1);
-[ RECORD 1 ]
repeat | x
so I think you are using a VARCHAR(500)
column, and you're looking at the wrong table or wrong instance of the database.
If you are using Linearlayout. its params should be "wrap_content" to add dynamic data in your layout xml. if you use match or fill parent then you cannot see the output.
It Should be like this.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
</LinearLayout>

You need to overload operator <<
for mystruct
class
Something like :-
friend ostream& operator << (ostream& os, const mystruct& m)
{
os << m.m_a <<" " << m.m_b << endl;
return os ;
}
See here
Most guides I've seen suggest that you should use
if A:
unless you have a reason to be more specific.
There are some slight differences. There are values other than None that return False, for example empty lists, or 0, so have a think about what it is you're really testing for.
to work this with unicode or fontawesome, you should add a span with class like below, because input tag not support pseudo classes like :after. this is not a direct solution

The problem is you are not in the correct directory. A simple fix in Jupyter is to do the following command:
Here is an example command to use in Jupyter:
%%bash
cd /home/ec2-user/ml_volume/GitHub_BMM
git show
Note you need to do the commands in the same cell.
The error message means that any method that calls showfile()
must either declare that it, in turn, throws IOException
, or the call must be inside a try
block that catches IOException
. When you call showfile()
, you do neither of these; for example, your filecontent
constructor neither declares IOException
nor contains a try
block.
The intent is that some method, somewhere, should contain a try
block, and catch and handle this exception. The compiler is trying to force you to handle the exception somewhere.
By the way, this code is (sorry to be so blunt) horrible. You don't close any of the files you open, the BufferedReader
always points to the first file, even though you seem to be trying to make it point to another, the loops contain off-by-one errors that will cause various exceptions, etc. When you do get this to compile, it will not work as you expect. I think you need to slow down a little.
It will definitely cost you more space & bandwidth if you want to use base64 encoded images. However if your site has a lot of small images you can decrease the page loading time by encoding your images to base64 and placing them into html. In this way, the client browser wont need to make a lot of connections to the images, but will have them in html.
Having a large Answer table, in and of itself, is not a problem. As long as the indexes and constraints are well defined you should be fine. Your second schema looks good to me.
The answer of ADTC works fine, but I've find another solution, so I post it here if someone wants something different.
I think ADTC's solution is better, but mine's also works.
Here is the other solution I found
select p.name
from person p
where instr(p.name,chr(8211)) > 0; --contains the character chr(8211)
--at least 1 time
Thank you.
Try adding the drive letter:
include_path='.;c:\xampplite\php\pear\PEAR'
also verify that PEAR.php is actually there, it might be in \php\ instead:
include_path='.;c:\xampplite\php'
you compiled your code using maven compile and then used maven test to run it worked fine. Now if you changed something in your code and then without compiling you are running it, you will get this error.
Solution: Again compile it and then run test. For me it worked this way.
Use Curses or ANSI escape sequences. Before you start spouting escape sequences, you should check that stdout is a tty. You can do this with sys.stdout.isatty()
. Here's a function pulled from a project of mine that prints output in red or green, depending on the status, using ANSI escape sequences:
def hilite(string, status, bold):
attr = []
if status:
# green
attr.append('32')
else:
# red
attr.append('31')
if bold:
attr.append('1')
return '\x1b[%sm%s\x1b[0m' % (';'.join(attr), string)
This works for me on the device (not simulator). Make sure you add the systemconfiguration framework.
#import <SystemConfiguration/CaptiveNetwork.h>
+ (NSString *)currentWifiSSID {
// Does not work on the simulator.
NSString *ssid = nil;
NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
for (NSString *ifnam in ifs) {
NSDictionary *info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
if (info[@"SSID"]) {
ssid = info[@"SSID"];
}
}
return ssid;
}
If
should be if
. Your program should look like this:
answer = raw_input("Is the information correct? Enter Y for yes or N for no")
if answer.upper() == 'Y':
print("this will do the calculation")
else:
exit()
Note also that the indentation is important, because it marks a block in Python.
I've been in similar situations. Have you tried running cleanup from the root of your workspace? I know sometimes a cleanup from a child directory (where the problem lies) doesn't work, and cleanup from the root of the workspace does.
If that still fails, since you had deleted a child dir somewhere. Try deleting 1 level higher from the child dir as well (assuming that is not the root), and re-trying update and cleanup.
If cleanup attempts aren't succeeding at any level then the answer is unfortunately checkout a new working copy.
In new jQuery 1.5 you can use:
$.ajax({
type: "GET",
url: "http://localhost:99000/Services.svc/ReturnPersons",
dataType: "jsonp",
success: readData(data),
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
})
From the Official documentation,
For example, to set the background color to orange:
<meta name="theme-color" content="#db5945">
In addition, Chrome will show beautiful high-res favicons when they’re provided. Chrome for Android picks the highest res icon that you provide, and we recommend providing a 192×192px PNG file. For example:
<link rel="icon" sizes="192x192" href="nice-highres.png">
Have a look at the examples below for a clearer understanding of the differences between the different operators:
> # Floating Division:
> 5/2
[1] 2.5
>
> # Integer Division:
> 5%/%2
[1] 2
>
> # Remainder:
> 5%%2
[1] 1
Before the days of jQuery you would use:
document.getElementById('findmebyid');
If this one line will save you an entire jQuery library, it might be worth while using it instead.
For those concerned about performance: Beginning your selector with an ID is always best as it uses native function document.getElementById.
// Fast:
$( "#container div.robotarm" );
// Super-fast:
$( "#container" ).find( "div.robotarm" );
The easiest solution is this( do these as root)
sudo su root
cd /etc
mkdir node
yum install wget
wget https://nodejs.org/dist/v9.0.0/node-v9.0.0-linux-x64.tar.gz
tar -xvf node-v9.0.0-linux-x64.tar.gz
cd node-v9.0.0-linux-x64/bin
./node -v
ln -s /etc/node-v9.0.0-linux-x64/bin/node node
If you are using Mongoose,
try {
const data = await GPSDatas.aggregate([
{
$match: { createdAt : { $gt: new Date() }
},
{
$sort: { createdAt: 1 }
}
])
console.log(data)
} catch(error) {
console.log(error)

On modern Windows this driver isn't available by default anymore, but you can download as Microsoft Access Database Engine 2010 Redistributable on the MS site. If your app is 32 bits be sure to download and install the 32 bits variant because to my knowledge the 32 and 64 bit variant cannot coexist.
Depending on how your app locates its db driver, that might be all that's needed. However, if you use an UDL file there's one extra step - you need to edit that file. Unfortunately, on a 64bits machine the wizard used to edit UDL files is 64 bits by default, it won't see the JET driver and just slap whatever driver it finds first in the UDL file. There are 2 ways to solve this issue:
C:\Windows\syswow64\rundll32.exe "C:\Program Files (x86)\Common Files\System\Ole DB\oledb32.dll",OpenDSLFile C:\path\to\your.udl
. Note that I could use this technique on a Win7 64 Pro, but it didn't work on a Server 2008R2 (could be my mistake, just mentioning)[oledb]
; Everything after this line is an OLE DB initstring
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Path\To\The\database.mdb;Persist Security Info=False
That should allow your app to start correctly.
This gist will do most of the work for you showing a menu when there are multiple devices connected:
$ adb $(android-select-device) shell
1) 02783201431feeee device 3) emulator-5554
2) 3832380FA5F30000 device 4) emulator-5556
Select the device to use, <Q> to quit:
To avoid typing you can just create an alias that included the device selection as explained here.
As per the HTML you have provided:
<tr>
<td>abc</td>
<td> </td>
</tr>
To locate the node with the string
you can use either of the following xpath based solutions:
Using text()
:
"//td[text()='\u00A0']"
Using contains()
:
"//td[contains(., '\u00A0')]"
However, ideally you may like to avoid the NO-BREAK SPACE character and use either of the following Locator Strategies:
Using the parent <tr>
node and following-sibling
:
"//tr//following-sibling::td[2]"
Using starts-with()
:
"//tr//td[last()]"
Using the preceeding <td>
node and following
node and
following-sibling`:
"//td[text()='abc']//following::td[1]"
You can find a relevant detailed discussion in:
I've investigated A LOT on how to properly manage 404s in MVC (specifically MVC3), and this, IMHO is the best solution I've come up with:
In global.asax:
public class MvcApplication : HttpApplication
{
protected void Application_EndRequest()
{
if (Context.Response.StatusCode == 404)
{
Response.Clear();
var rd = new RouteData();
rd.DataTokens["area"] = "AreaName"; // In case controller is in another area
rd.Values["controller"] = "Errors";
rd.Values["action"] = "NotFound";
IController c = new ErrorsController();
c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));
}
}
}
ErrorsController:
public sealed class ErrorsController : Controller
{
public ActionResult NotFound()
{
ActionResult result;
object model = Request.Url.PathAndQuery;
if (!Request.IsAjaxRequest())
result = View(model);
else
result = PartialView("_NotFound", model);
return result;
}
}
Edit:
If you're using IoC (e.g. AutoFac), you should create your controller using:
var rc = new RequestContext(new HttpContextWrapper(Context), rd);
var c = ControllerBuilder.Current.GetControllerFactory().CreateController(rc, "Errors");
c.Execute(rc);
Instead of
IController c = new ErrorsController();
c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));
(Optional)
Explanation:
There are 6 scenarios that I can think of where an ASP.NET MVC3 apps can generate 404s.
Generated by ASP.NET:
Generated by ASP.NET MVC:
Scenario 2: URL matches a route, but specifies a controller that doesn't exist.
Scenario 3: URL matches a route, but specifies an action that doesn't exist.
Manually generated:
Scenario 4: An action returns an HttpNotFoundResult by using the method HttpNotFound().
Scenario 5: An action throws an HttpException with the status code 404.
Scenario 6: An actions manually modifies the Response.StatusCode property to 404.
Objectives
(A) Show a custom 404 error page to the user.
(B) Maintain the 404 status code on the client response (specially important for SEO).
(C) Send the response directly, without involving a 302 redirection.

People that have troubled with this before even tried to create their own libraries (see http://aboutcode.net/2011/02/26/handling-not-found-with-asp-net-mvc3.html). But the previous solution seems to cover all the scenarios without the complexity of using an external library.
I don't have gnome-terminal installed but you should be able to do this by using a DBUS call on the command-line using dbus-send.
length of string ==how many bits that string having, size==size of those bits, In strings both are same if the editor allocates size of character is 1 byte
I know this isn't exactly how you want to do this, but it could be a start:
SELECT *
FROM (SELECT *, DATEPART(yy, column_dateTime) as Year,
DATEPART(mm, column_dateTime) as Month,
DATEPART(dd, column_dateTime) as Day
FROM table1)
WHERE Year = '2008'
AND Month = '8'
AND Day = '14'

is set in each except block, so that behaviour is complemented in the no-error case in else
.
Of course, I'm describing this as a pattern that may turn up in your own code someday. In this specific case, you just set inconsistency_type
to 0 before the try
block anyway.
When using WebAPI, you should just return the Object rather than specifically returning Json, as the API will either return JSON or XML depending on the request.
I am not sure why your WebAPI is returning an ActionResult, but I would change the code to something like;
public IEnumerable<ListItems> GetAllNotificationSettings()
{
var result = new List<ListItems>();
// Filling the list with data here...
// Then I return the list
return result;
}
This will result in JSON if you are calling it from some AJAX code.
P.S
WebAPI is supposed to be RESTful, so your Controller should be called ListItemController
and your Method should just be called Get
. But that is for another day.
I think that I remember looking at a performance comparison between int.TryParse and int.Parse Regex and char.IsNumber and char.IsNumber was fastest. At any rate, whatever the performance, here's one more way to do it.
bool isNumeric = true;
foreach (char c in "12345")
{
if (!Char.IsNumber(c))
{
isNumeric = false;
break;
}
}
I hope you got your answer regarding which is default constructor. But I am giving below statements to correct the comments given.
Java does not initialize any local variable to any default value. So if you are creating an Object of a class it will call default constructor and provide default values to Object.
Default constructor provides the default values to the object like 0, null etc. depending on the type.
Please refer below link for more details.
If the .project
and .classpath
are already committed, then they need to be removed from the index (but not the disk)
git rm --cached .project
git rm --cached .classpath
Then the .gitignore
would work (and that file can be added and shared through clones).
For instance, this gitignore.io/api/eclipse
file will then work, which does include:
# Eclipse Core
.project
# JDT-specific (Eclipse Java Development Tools)
.classpath
Note that you could use a "Template Directory" when cloning (make sure your users have an environment variable $GIT_TEMPLATE_DIR
set to a shared folder accessible by all).
That template folder can contain an info/exclude
file, with ignore rules that you want enforced for all repos, including the new ones (git init
) that any user would use.
When you change the index, you need to commit the change and push it.
Then the file is removed from the repository. So the newbies cannot checkout the files.classpath
and.project
from the repo.
The most succinct way to do this is:
Get-WmiObject -Class win32_computersystem -Property *
You can run something like this:
sqlcmd -S MyServer -d myDB -E -Q "select col1, col2, col3 from SomeTable"
-o "MyData.csv" -h-1 -s"," -w 700
-h-1
removes column name headers from the result-s","
sets the column seperator to , -w 700
sets the row width to 700 chars (this will need to be as wide as the longest row or it will wrap to the next line)Open the file for 'append' rather than 'write'.
with open('file.txt', 'a') as file:
file.write('input')
Jerking happens when the parent div ".collapse" has padding.
Padding goes on the child div, not the parent. jQuery is animating the height, not the padding.
Example:
<div class="form-group">
<a for="collapseOne" data-toggle="collapse" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">+ addInfo</a>
<div class="collapse" id="collapseOne" style="padding: 0;">
<textarea class="form-control" rows="4" style="padding: 20px;"></textarea>
</div>
</div>
<div class="form-group">
<a for="collapseTwo" data-toggle="collapse" href="#collapseTwo" aria-expanded="true" aria-controls="collapseOne">+ subtitle</a>
<input type="text" class="form-control collapse" id="collapseTwo">
</div>
Hope this helps.
The data itself is one or more lucene indices, since you can have multiple shards. What you also need to backup is the cluster state, which contains all sorts of information regarding the cluster, the available indices, their mappings, the shards they are composed of etc.
It's all within the data
directory though, you can just copy it. Its structure is pretty intuitive. Right before copying it's better to disable automatic flush (in order to backup a consistent view of the index and avoiding writes on it while copying files), issue a manual flush, disable allocation as well. Remember to copy the directory from all nodes.
Also, next major version of elasticsearch is going to provide a new snapshot/restore api that will allow you to perform incremental snapshots and restore them too via api. Here is the related github issue: https://github.com/elasticsearch/elasticsearch/issues/3826.
This is now possible with move_to_end(key, last=True)
>>> d = OrderedDict.fromkeys('abcde')
>>> d.move_to_end('b')
>>> ''.join(d.keys())
'acdeb'
>>> d.move_to_end('b', last=False)
>>> ''.join(d.keys())
'bacde'

A SELECT INTO
statement will throw an error if it returns anything other than 1 row. If it returns 0 rows, you'll get a no_data_found
exception. If it returns more than 1 row, you'll get a too_many_rows
exception. Unless you know that there will always be exactly 1 employee with a salary greater than 3000, you do not want a SELECT INTO
statement here.
Most likely, you want to use a cursor to iterate over (potentially) multiple rows of data (I'm also assuming that you intended to do a proper join between the two tables rather than doing a Cartesian product so I'm assuming that there is a departmentID
column in both tables)
BEGIN
FOR rec IN (SELECT EMPLOYEE.EMPID,
EMPLOYEE.ENAME,
EMPLOYEE.DESIGNATION,
EMPLOYEE.SALARY,
DEPARTMENT.DEPT_NAME
FROM EMPLOYEE,
DEPARTMENT
WHERE employee.departmentID = department.departmentID
AND EMPLOYEE.SALARY > 3000)
LOOP
DBMS_OUTPUT.PUT_LINE ('Employee Nnumber: ' || rec.EMPID);
DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Name: ' || rec.ENAME);
DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Designation: ' || rec.DESIGNATION);
DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Salary: ' || rec.SALARY);
DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Department: ' || rec.DEPT_NAME);
END LOOP;
END;
I'm assuming that you are just learning PL/SQL as well. In real code, you'd never use dbms_output
like this and would not depend on anyone seeing data that you write to the dbms_output
buffer.
Vue2: if you only want to detect change on input blur (e.g. after press enter or click somewhere else) do (more info here)
<input @change="foo" v-model... >
If you wanna detect single character changes (during user typing) use
<input @keydown="foo" v-model... >
You can also use @keyup
and @input
events. If you wanna to pass additional parameters use in template e.g. @keyDown="foo($event, param1, param2)"

This worked for me:
cp <path_to>/libstdc++.so.6 $PWD
./<executable>
This tidbit came from @kerin (comment provided above):
you might check out http://stackoverflow.com/questions/13636513/linking-libstdc-statically-any-gotchas
From that link:
If you put the newer libstdc++.so in the same directory as the executable it will be found at run-time, problem solved.
The error I was getting mentioned that libstdc++.so.6 was coming from /usr/lib64/, but this is not the library I linked against! The message looked like:
<executing_binary>: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by <executing_binary>)
I did verify that LD_LIBRARY_PATH had the directory (and that it was the first path). For some reason at runtime it was still looking at /usr/lib64/libstdc++.so.6.
I took the advice from the article above and copied the libstdc++.so.6 from where I linked into the directory with my executable, ran from there, and it worked!
One important difference is that both String.split() and Scanner can produce empty strings but StringTokenizer never does it.
For example:
String str = "ab cd ef";
StringTokenizer st = new StringTokenizer(str, " ");
for (int i = 0; st.hasMoreTokens(); i++) System.out.println("#" + i + ": " + st.nextToken());
String[] split = str.split(" ");
for (int i = 0; i < split.length; i++) System.out.println("#" + i + ": " + split[i]);
Scanner sc = new Scanner(str).useDelimiter(" ");
for (int i = 0; sc.hasNext(); i++) System.out.println("#" + i + ": " + sc.next());
Output:
//StringTokenizer
#0: ab
#1: cd
#2: ef
//String.split()
#0: ab
#1: cd
#2:
#3: ef
//Scanner
#0: ab
#1: cd
#2:
#3: ef
This is because the delimiter for String.split() and Scanner.useDelimiter() is not just a string, but a regular expression. We can replace the delimiter " " with " +" in the example above to make them behave like StringTokenizer.
The following program will add the python executable path and the subdir Scripts (which is where e.g. pip and easy_install are installed) to your environment. It finds the path to the python executable from the registry key binding the .py extension. It will remove old python paths in your environment. Works with XP (and probably Vista) as well. It only uses modules that come with the basic windows installer.

The most likely explanations for that error are:
CreateProcess
requires you to provide an executable file. If you wish to be able to open any file with its associated application then you need ShellExecute
rather than CreateProcess
.Reading down to the bottom of the code, I can see that the problem is number 1.

I missed the following line in my application.js
//= require jquery_ujs
I replaced it and its working..
======= UPDATED =========
After 5 years, I am back with Same error, now I have brand new Rails 5.1.6, and I found this post again. Just like circle of life.
Now what was the issue is: Rails 5.1 removed support for jquery and jquery_ujs by default, and added
//= require rails-ujs in application.js
It does the following things:
But why is it not including the csrf token for ajax request? If anyone know about this in detail just comment me. I appreciate that.
Anyway I added the following in my custom js file to make it work (Thanks for other answers to help me reach this code):

$.ajaxSetup({
headers: {
'X-CSRF-Token': Rails.csrfToken()
}

If you are still recieving the InvalidKeyException when running my AES encryption program with 256 bit keys, but not with 128 bit keys, it is because you have not installed the new policy JAR files correctly, and has nothing to do with BouncyCastle (which is also restrained by those policy files). Try uninstalling, then re-installing java and then replaceing the old jar's with the new unlimited strength ones. Other than that, I'm out of ideas, best of luck.
You can see the policy files themselves if you open up the lib/security/local_policy.jar and US_export_policy.jar files in winzip and look at the conatined *.policy files in notepad and make sure they look like this:
default_local.policy:
// Country-specific policy file for countries with no limits on crypto strength.
grant {
// There is no restriction to any algorithms.
permission javax.crypto.CryptoAllPermission;
};
default_US_export.policy:
// Manufacturing policy file.
grant {
// There is no restriction to any algorithms.
permission javax.crypto.CryptoAllPermission;
};
The disadvantages of document.write mainly depends on these 3 factors:
a) Implementation
The document.write() is mostly used to write content to the screen as soon as that content is needed. This means it happens anywhere, either in a JavaScript file or inside a script tag within an HTML file. With the script tag being placed anywhere within such an HTML file, it is a bad idea to have document.write() statements inside script blocks that are intertwined with HTML inside a web page.
b) Rendering
Well designed code in general will take any dynamically generated content, store it in memory, keep manipulating it as it passes through the code before it finally gets spit out to the screen. So to reiterate the last point in the preceding section, rendering content in-place may render faster than other content that may be relied upon, but it may not be available to the other code that in turn requires the content to be rendered for processing. To solve this dilemma we need to get rid of the document.write() and implement it the right way.
c) Impossible Manipulation
Once it's written it's done and over with. We cannot go back to manipulate it without tapping into the DOM.
In your JSON format, it do not have starting JSON object
Like :
{
"info" : <!-- this is starting JSON object -->
{
"caller":"getPoiById",
"results":
{
"indexForPhone":0,
"indexForEmail":"NULL",
.
.
}
}
}
Above Json starts with info
as JSON object. So while executing :
JSONObject json = new JSONObject(result); // create JSON obj from string
JSONObject json2 = json.getJSONObject("info"); // this will return correct
Now, we can access result
field :
JSONObject jsonResult = json2.getJSONObject("results");
test = json2.getString("name"); // returns "Marina Rasche Werft GmbH & Co. KG"
I think this was missing and so the problem was solved while we use JSONTokener
like answer of yours.
Your answer is very fine. Just i think i add this information so i answered

As Javier says:
And if you wanted to see it in action I've created a demo sheet and you can see the code if you take a copy.
The chosen answer works in this case.
But the question was about finding the element based on radiogroup and dynamic id, and the answer can also leave the displayed radio button unaffected.
This line does selects exactly what was asked for while showing the change on screen as well.
$('input:radio[name=cols][id='+ newcol +']').click();
This declaration:
double F[1000][1000000];
would occupy 8 * 1000 * 1000000 bytes on a typical x86 system. This is about 7.45 GB. Chances are your system is running out of memory when trying to execute your code, which results in a segmentation fault.
Use the set -e
builtin:
#!/bin/bash
set -e
# Any subsequent(*) commands which fail will cause the shell script to exit immediately
Alternatively, you can pass -e
on the command line:
bash -e my_script.sh
You can also disable this behavior with set +e
.
You may also want to employ all or some of the the -e
-u
-x
and -o pipefail
options like so:
set -euxo pipefail
-e
exits on error, -u
errors on undefined variables, and -o (for option) pipefail
exits on command pipe failures. Some gotchas and workarounds are documented well here.
(*) Note:
The shell does not exit if the command that fails is part of the command list immediately following a while or until keyword, part of the test following the if or elif reserved words, part of any command executed in a && or || list except the command following the final && or ||, any command in a pipeline but the last, or if the command's return value is being inverted with !
(from man bash
)
I wrote an example for a custom Timestamp.class
serialization/deserialization, but you could use it for what ever you want.
When creating the object mapper do something like this:
public class JsonUtils {
public static ObjectMapper objectMapper = null;
static {
objectMapper = new ObjectMapper();
SimpleModule s = new SimpleModule();
s.addSerializer(Timestamp.class, new TimestampSerializerTypeHandler());
s.addDeserializer(Timestamp.class, new TimestampDeserializerTypeHandler());
objectMapper.registerModule(s);
};
}
for example in java ee
you could initialize it with this:
import java.time.LocalDateTime;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.module.SimpleModule;
@Provider
public class JacksonConfig implements ContextResolver<ObjectMapper> {
private final ObjectMapper objectMapper;
public JacksonConfig() {
objectMapper = new ObjectMapper();
SimpleModule s = new SimpleModule();
s.addSerializer(Timestamp.class, new TimestampSerializerTypeHandler());
s.addDeserializer(Timestamp.class, new TimestampDeserializerTypeHandler());
objectMapper.registerModule(s);
};
@Override
public ObjectMapper getContext(Class<?> type) {
return objectMapper;
}
}
where the serializer should be something like this:
import java.io.IOException;
import java.sql.Timestamp;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
public class TimestampSerializerTypeHandler extends JsonSerializer<Timestamp> {
@Override
public void serialize(Timestamp value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException {
String stringValue = value.toString();
if(stringValue != null && !stringValue.isEmpty() && !stringValue.equals("null")) {
jgen.writeString(stringValue);
} else {
jgen.writeNull();
}
}
@Override
public Class<Timestamp> handledType() {
return Timestamp.class;
}
}
and deserializer something like this:
import java.io.IOException;
import java.sql.Timestamp;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonDeserializer;
import com.fasterxml.jackson.databind.SerializerProvider;
public class TimestampDeserializerTypeHandler extends JsonDeserializer<Timestamp> {
@Override
public Timestamp deserialize(JsonParser jp, DeserializationContext ds) throws IOException, JsonProcessingException {
SqlTimestampConverter s = new SqlTimestampConverter();
String value = jp.getValueAsString();
if(value != null && !value.isEmpty() && !value.equals("null"))
return (Timestamp) s.convert(Timestamp.class, value);
return null;
}
@Override
public Class<Timestamp> handledType() {
return Timestamp.class;
}
}
Here's the method I use (for similar things, not just title):
<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title><!--TITLE--></title>
</head>
<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer
// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
?>
PHP usually works be executing any bits of code and printing all output directly to the browser. If you say "echo 'Some text here.';"
, that string will get sent the browser and is emptied from memory.
What output buffering does is say "Print all output to a buffer. Hold onto it. Don't send ANYTHING to the browser until I tell you to."
So what this does is it buffers all your pages' HTML into the buffer, then at the very end, after the tag, it uses ob_get_contents () to get the contents of the buffer (which is usually all your page's HTML source code which would have been sent the browser already) and puts that into a string.
ob_end_clean () empties the buffer and frees some memory. We don't need the source code anymore because we just stored it in $pageContents.
Then, lastly, I do a simple find & replace on your page's source code ($pageContents) for any instances of '' and replace them to whatever the $pageTitle variable was set to. Of course, it will then replace <title><!--TITLE--></title>
with Your Page's Title. After that, I echo the $pageContents, just like the browser would have.
It effectively holds onto output so you can manipulate it before sending it to the browser.
Hopefully my comments are clear enough. Look up ob_start () in the php manual ( http://php.net/ob_start ) if you want to know exactly how that works (and you should) :)
To correctly save the instance state of Fragment
you should do the following:
1. In the fragment, save instance state by overriding onSaveInstanceState()
and restore in onActivityCreated()
:
class MyFragment extends Fragment {
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
...
if (savedInstanceState != null) {
//Restore the fragment's state here
}
}
...
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//Save the fragment's state here
}
}
2. And important point, in the activity, you have to save the fragment's instance in onSaveInstanceState()
and restore in onCreate()
.
class MyActivity extends Activity {
private MyFragment
public void onCreate(Bundle savedInstanceState) {
...
if (savedInstanceState != null) {
//Restore the fragment's instance
mMyFragment = getSupportFragmentManager().getFragment(savedInstanceState, "myFragmentName");
...
}
...
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//Save the fragment's instance
getSupportFragmentManager().putFragment(outState, "myFragmentName", mMyFragment);
}
}
Hope this helps.
You should put javascript tag in your html file.
because browser load your webpage according to html flow, you should put your javascript file<script src="javascript/game.js">
after the <canvas>
element tag. otherwise,if you put your javascript in the header of html.Browser load script first but it doesn't find the canvas. So your canvas doesn't work.
None of these methods work in special cases like using a symbolic link to the exe, they will return the location of the link not the actual exe.
So can use QueryFullProcessImageName to get around that:
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
using System.Diagnostics;
internal static class NativeMethods
{
[DllImport("kernel32.dll", SetLastError = true)]
internal static extern bool QueryFullProcessImageName([In]IntPtr hProcess, [In]int dwFlags, [Out]StringBuilder lpExeName, ref int lpdwSize);
[DllImport("kernel32.dll", SetLastError = true)]
internal static extern IntPtr OpenProcess(
UInt32 dwDesiredAccess,
[MarshalAs(UnmanagedType.Bool)]
Boolean bInheritHandle,
Int32 dwProcessId
);
}
public static class utils
{
private const UInt32 PROCESS_QUERY_INFORMATION = 0x400;
private const UInt32 PROCESS_VM_READ = 0x010;
public static string getfolder()
{
Int32 pid = Process.GetCurrentProcess().Id;
int capacity = 2000;
StringBuilder sb = new StringBuilder(capacity);
IntPtr proc;
if ((proc = NativeMethods.OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, false, pid)) == IntPtr.Zero)
return "";
NativeMethods.QueryFullProcessImageName(proc, 0, sb, ref capacity);
string fullPath = sb.ToString(0, capacity);
return Path.GetDirectoryName(fullPath) + @"\";
}
}
This site says to try:
import datetime as dt
start="09:35:23"
end="10:23:00"
start_dt = dt.datetime.strptime(start, '%H:%M:%S')
end_dt = dt.datetime.strptime(end, '%H:%M:%S')
diff = (end_dt - start_dt)
diff.seconds/60
This forum uses time.mktime()
Old:
maxrss states the maximum available memory for the process. 0 means that no limit is put upon the process. What you probably want is unshared data usage
ru_idrss
.
New: It seems that the above does not actually work, as the kernel does not fill most of the values. What does work is to get the information from proc. Instead of parsing it oneself though, it is easier to use libproc (part of procps) as follows:
// getrusage.c
#include <stdio.h>
#include <proc/readproc.h>
int main() {
struct proc_t usage;
look_up_our_self(&usage);
printf("usage: %lu\n", usage.vsize);
}
Compile with "gcc -o getrusage getrusage.c -lproc
"
Following this resource page, if the length of x is varying, we can use:
', '.join(['%.2f']*len(x))
to create a place holder for each element from the list x
. Here is the example:
x = [1/3.0, 1/6.0, 0.678]
s = ("elements in the list are ["+', '.join(['%.2f']*len(x))+"]") % tuple(x)
print s
>>> elements in the list are [0.33, 0.17, 0.68]
I know this is an old thread, but I landed here when my row deletes were blocked by foreign key constraints. In my case, my table design permitted "NULL" values in the constrained column. In the rows to be deleted, I changed the constrained column value to "NULL" (which does not violate the Foreign Key Constraint) and then deleted all the rows.
You may use this in shell:
wget -r --no-parent http://abc.tamu.edu/projects/tzivi/repository/revisions/2/raw/tzivi/
The Parameters are:
-r //recursive Download
and
--no-parent // Don´t download something from the parent directory
If you don't want to download the entire content, you may use:
-l1 just download the directory (tzivi in your case)
-l2 download the directory and all level 1 subfolders ('tzivi/something' but not 'tivizi/somthing/foo')
And so on. If you insert no -l
option, wget
will use -l 5
automatically.
If you insert a -l 0
you´ll download the whole Internet, because wget
will follow every link it finds.
Here is what made the error disappear for me:
Close eclipse, open up a terminal window and run:
$ mvn clean eclipse:clean eclipse:eclipse
Are you using Maven? If so,
To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.
And then clean
Edit 1:
If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.
Edit 2:
You can also try going into the folder where you have all your projects and delete the .metadata
for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.
View.INVISIBLE->The View is invisible but it will occupy some space in layout
View.GONE->The View is not visible and it will not occupy any space in layout
This is another way and is good to use with some text editors that are unable to correctly highlight every intricate code you create:
read -r -d '' str < <(cat somefile.txt)
echo "${#str}"
echo "$str"
All you need to do is bind touchstart on a parent. Something like this will work:
$('body').on('touchstart', function() {});
You don't need to do anything in the function, leave it empty. This will be enough to get hovers on touch, so a touch behaves more like :hover and less like :active. iOS magic.
Right now there is no view:clear command. For laravel 4 this can probably help you: https://gist.github.com/cjonstrup/8228165
Disabling caching can be done by skipping blade. View caching is done because blade compiling each time is a waste of time.
Try using Web API HttpClient
static async Task RunAsync()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://domain.com/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// HTTP POST
var obj = new MyObject() { Str = "MyString"};
response = await client.PostAsJsonAsync("POST URL GOES HERE?", obj );
if (response.IsSuccessStatusCode)
{
response.//.. Contains the returned content.
}
}
}

You state in the comments that the returned JSON is this:
{
"dstOffset" : 3600,
"rawOffset" : 36000,
"status" : "OK",
"timeZoneId" : "Australia/Hobart",
"timeZoneName" : "Australian Eastern Daylight Time"
}
You're telling Gson that you have an array of Post
objects:
List<Post> postsList = Arrays.asList(gson.fromJson(reader,
Post[].class));
You don't. The JSON represents exactly one Post
object, and Gson is telling you that.
Change your code to be:
Post post = gson.fromJson(reader, Post.class);
BSD's
for i in $(seq 1 254); do (ping -c1 -W5 192.168.1.$i >/dev/null && echo "192.168.1.$i" &) ;done
This is one way.
List<int> list = new List<int>{ 1, 2, 3, 4, 5 };
This is another way.
List<int> list2 = new List<int>();
list2.Add(1);
list2.Add(2);
Same goes with strings.
Eg:
List<string> list3 = new List<string> { "Hello", "World" };
I'm going on a bit of an assumption here, but I'm assuming the logic inside the procedure gets split up via task. And you cant have nullable parameters as @Yuck suggested because of the dynamics of the parameters?
So going by my assumption
If TaskName = "Path1" Then Something
If TaskName = "Path2" Then Something Else
My initial thought is, if you have separate functions with business-logic you need to create, and you can determine that you have say 5-10 different scenarios, rather write individual stored procedures as needed, instead of trying one huge one solution fits all approach. Might get a bit messy to maintain.
But if you must...
Why not try dynamic SQL, as suggested by @E.J Brennan (Forgive me, i haven't touched SQL in a while so my syntax might be rusty) That being said i don't know if its the best approach, but could this could possibly meet your needs?
CREATE PROCEDURE GetTaskEvents
@TaskName varchar(50)
@Values varchar(200)
AS
BEGIN
DECLARE @SQL VARCHAR(MAX)
IF @TaskName = 'Something'
BEGIN
@SQL = 'INSERT INTO.....' + CHAR(13)
@SQL += @Values + CHAR(13)
END
IF @TaskName = 'Something Else'
BEGIN
@SQL = 'DELETE SOMETHING WHERE' + CHAR(13)
@SQL += @Values + CHAR(13)
END
PRINT(@SQL)
EXEC(@SQL)
END
(The CHAR(13) adds a new line.. an old habbit i picked up somewhere, used to help debugging/reading dynamic procedures when running SQL profiler.)
protected void UpdateButton_Click(object sender, EventArgs e)
{
var values = string.Format("Name={0}&Family={1}&Id={2}", NameToUpdateTextBox.Text, FamilyToUpdateTextBox.Text, IdToUpdateTextBox.Text);
var bytes = Encoding.ASCII.GetBytes(values);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(string.Format("http://localhost:51436/api/employees"));
request.Method = "PUT";
request.ContentType = "application/x-www-form-urlencoded";
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(bytes, 0, bytes.Length);
}
var response = (HttpWebResponse) request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
UpdateResponseLabel.Text = "Update completed";
else
UpdateResponseLabel.Text = "Error in update";
}
This works for me. It also works for lower version too. Add this to your syles.xml
<style name="ProgressBarTheme" parent="ThemeOverlay.AppCompat.Light">
<item name="colorAccent">@color/colorPrimary</item>
</style>
And use it like this in xml
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:theme="@style/ProgressBarTheme"
/>
Simple Insert/Select sp's work great until the row count exceeds 1 mil. I've watched tempdb file explode trying to insert/select 20 mil + rows. The simplest solution is SSIS setting the batch row size buffer to 5000 and commit size buffer to 1000.
To get the number of days the easiest way would be:
SELECT EXTRACT(DAY FROM NOW() - '2014-08-02 08:10:56');
As far as I know it would return the same as:
SELECT (EXTRACT(epoch FROM (SELECT (NOW() - '2014-08-02 08:10:56')))/86400)::int;
Use =IF(H15+G16-F16=0,"",H15+G16-F16)
I just lowered the height to 28px on the .login-icon [class*='icon-'] Here's the fiddle: http://jsfiddle.net/mZHg7/

vertical-align: baseline;
}
var x = {
a: (window.secreta = 5),
b: (window.secretb = 6),
c: window.secreta + window.secretb
};
This is almost identical to @slicedtoad's answer, but doesn't use a function.
Please use dataset
var article = document.querySelector('#electriccars'),
data = article.dataset;
// data.columns -> "3"
// data.indexnumber -> "12314"
// data.parent -> "cars"
so in your case for setting data:
getElementById('item1').dataset.icon = "base2.gif";
Just use git reset
without the --hard
flag:
git reset HEAD~1
PS: On Unix based systems you can use HEAD^
which is equal to HEAD~1
. On Windows HEAD^
will not work because ^
signals a line continuation. So your command prompt will just ask you More?
.
Run eclipse.exe file as an Administrator. It worked for me
First of all: you should always import mockito static, this way the code will be much more readable (and intuitive):
import static org.mockito.Mockito.*;
There are actually many ways to achieve this, however it's (arguably) cleaner to use the
verify(yourMock, times(0)).someMethod();
method all over your tests, when on other Tests you use it to assert a certain amount of executions like this:
verify(yourMock, times(5)).someMethod();
Alternatives are:
verify(yourMock, never()).someMethod();
Alternatively - when you really want to make sure a certain mocked Object is actually NOT called at all - you can use:
verifyZeroInteractions(yourMock)
A shorter example
private static final Charset UTF_8 = Charset.forName("UTF-8");
String text = "Hello World!";
byte[] bytes = text.getBytes(UTF_8);
System.out.println("bytes= "+Arrays.toString(bytes));
System.out.println("text again= "+new String(bytes, UTF_8));
prints
bytes= [72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33]
text again= Hello World!
You can do something like
for(var k in result) {
console.log(k, result[k]);
}
which loops over all the keys in the returned json and prints the values. However, if you have a nested structure, you will need to use
typeof result[k] === "object"
to determine if you have to loop over the nested objects. Most APIs I have used, the developers know the structure of what is being returned, so this is unnecessary. However, I suppose it's possible that this expectation is not good for all cases.
The pipe character |
has a special meaning in regular expressions. a|b
means "match either a

". If you want to match a literal |
character, you need to escape it:
... | Select-String -Pattern 'H\|159' -NotMatch | ...
Found solution on css-tricks
const element = document.getElementById('img')
element.classList.remove('classname'); // reset animation
void element.offsetWidth; // trigger reflow
element.classList.add('classname'); // start animation
I am also a beginner and I've just managed to crack this using two nested for loops.
I looked at the answers here and tbh they're a bit advanced for me so I thought I'd share mine to help all the other newbies out there.
P.S. It's for a Whack-A-Mole game hence why the array is called 'moleGrid'.
public static void printGrid() {
for (int i = 0; i < moleGrid.length; i++) {
for (int j = 0; j < moleGrid[0].length; j++) {
if (j == 0 || j % (moleGrid.length - 1) != 0) {
System.out.print(moleGrid[i][j]);
}
else {
System.out.println(moleGrid[i][j]);
}
}
}
}
Hope it helps!

GDB Dashboard
https://github.com/cyrus-and/gdb-dashboard
This GDB configuration uses the official GDB Python API to show us whatever we want whenever GDB stops after for example next
, much like TUI.
However I have found that this implementation is a more robust and configurable alternative to the built-in GDB TUI mode as explained at: gdb split view with code
For example, we can configure GDB Dashboard to show disassembly, source, registers and stack with:
dashboard -layout source assembly registers stack
Here is what it looks like if you enable all available views instead:

It's not an ideal solution but here's a quick and dirty example that shows how you could store login info in the PHP code:
<?php
session_start();
$userinfo = array(
'user1'=>'password1',
'user2'=>'password2'
);
if(isset($_GET['logout'])) {
$_SESSION['username'] = '';
header('Location: ' . $_SERVER['PHP_SELF']);
}
if(isset($_POST['username'])) {
if($userinfo[$_POST['username']] == $_POST['password']) {
$_SESSION['username'] = $_POST['username'];

Here's my solution, suitable for use in a PS1, or for automatically labeling a release
If you are checked out at a branch, you get the branch name.
If you are in a just init'd git project, you just get '@'
If you are headless, you get a nice human name relative to some branch or tag, with an '@' preceding the name.
If you are headless and not an ancestor of some branch or tag you just get the short SHA1.
function we_are_in_git_work_tree {
git rev-parse --is-inside-work-tree &> /dev/null
}
function parse_git_branch {
if we_are_in_git_work_tree
then
local BR=$(git rev-parse --symbolic-full-name --abbrev-ref HEAD 2> /dev/null)
if [ "$BR" == HEAD ]
then
local NM=$(git name-rev --name-only HEAD 2> /dev/null)
if [ "$NM" != undefined ]
then echo -n "@$NM"
else git rev-parse --short HEAD 2> /dev/null
fi
else
echo -n $BR
fi
fi
}
You can remove the if we_are_in_git_work_tree
bit if you like; I just use it in another function in my PS1 which you can view in full here: PS1 line with git current branch and colors
2014 answer: classList.toggle()
is the standard and supported by most browsers.
Older browsers can use use classlist.js for classList.toggle():
var menu = document.querySelector('.menu') // Using a class instead, see note below.
menu.classList.toggle('hidden-phone');
As an aside, you shouldn't be using IDs (they leak globals into the JS window
object).
My situation was that I have a bare repo that the team pushes to, and a clone of that sitting right next to it. This set of lines in a Makefile work correctly for me:
git reset --hard
git remote update --prune
git pull --rebase --all
git cherry-pick -n remotes/origin/$(BRANCH)
By keeping the master of the bare repo up to date, we are able to cherry-pick a proposed change published to the bare repo. We also have a (more complicated) way to cherry-pick multiple braches for consolidated review and testing.
If "knows nothing" means "can't be used as a remote", then this doesn't help, but this SO question came up as I was googling around to come up with this workflow so I thought I'd contribute back.
Step 1 : Login in Bitbucket
Step 2 : Select Your Repository in Repositories list.
Step 3 : Select branches in left hand side menu.
Step4 : Cursor point on branch click on three dots (...) Select Delete (See in Bellow Image)
My understanding of marshalling is different to the other answers.
Serialization:
To Produce or rehydrate a wire-format version of an object graph utilizing a convention.
Marshalling:
To Produce or rehydrate a wire-format version of an object graph by utilizing a mapping file, so that the results can be customized. The tool may start by adhering to a convention, but the important difference is the ability to customize results.
Contract First Development:
Marshalling is important within the context of contract first development.
I had the same issue and I needed an algorithm using a config file. In This way you can use multiple fields define by a configuration file (simulate just by a List<String) config)
public static void test() {
// Associate your configName with your Comparator
Map<String, Comparator<DocumentDto>> map = new HashMap<>();
map.put("id", new IdSort());
map.put("createUser", new DocumentUserSort());
map.put("documentType", new DocumentTypeSort());
/**
In your config.yml file, you'll have something like
sortlist:
- documentType
- createUser
- id
*/
List<String> config = new ArrayList<>();
config.add("documentType");
config.add("createUser");
config.add("id");
List<Comparator<DocumentDto>> sorts = new ArrayList<>();
for (String comparator : config) {
sorts.add(map.get(comparator));
}
// Begin creation of the list
DocumentDto d1 = new DocumentDto();
d1.setDocumentType(new DocumentTypeDto());
d1.getDocumentType().setCode("A");
d1.setId(1);
d1.setCreateUser("Djory");
DocumentDto d2 = new DocumentDto();
d2.setDocumentType(new DocumentTypeDto());
d2.getDocumentType().setCode("A");
d2.setId(2);
d2.setCreateUser("Alex");
DocumentDto d3 = new DocumentDto();
d3.setDocumentType(new DocumentTypeDto());
d3.getDocumentType().setCode("A");
d3.setId(3);
d3.setCreateUser("Djory");
DocumentDto d4 = new DocumentDto();
d4.setDocumentType(new DocumentTypeDto());
d4.getDocumentType().setCode("A");
d4.setId(4);
d4.setCreateUser("Alex");
DocumentDto d5 = new DocumentDto();
d5.setDocumentType(new DocumentTypeDto());
d5.getDocumentType().setCode("D");
d5.setId(5);
d5.setCreateUser("Djory");
DocumentDto d6 = new DocumentDto();
d6.setDocumentType(new DocumentTypeDto());
d6.getDocumentType().setCode("B");
d6.setId(6);
d6.setCreateUser("Alex");
DocumentDto d7 = new DocumentDto();
d7.setDocumentType(new DocumentTypeDto());
d7.getDocumentType().setCode("B");
d7.setId(7);
d7.setCreateUser("Alex");
List<DocumentDto> documents = new ArrayList<>();
documents.add(d1);
documents.add(d2);
documents.add(d3);
documents.add(d4);
documents.add(d5);
documents.add(d6);
documents.add(d7);
// End creation of the list
// The Sort
Stream<DocumentDto> docStream = documents.stream();
// we need to reverse this list in order to sort by documentType first because stream are pull-based, last sorted() will have the priority
Collections.reverse(sorts);
for(Comparator<DocumentDto> entitySort : sorts){
docStream = docStream.sorted(entitySort);
}
documents = docStream.collect(Collectors.toList());
// documents has been sorted has you configured
// in case of equality second sort will be used.
System.out.println(documents);
}
Comparator objects are really simple.
public class IdSort implements Comparator<DocumentDto> {
@Override
public int compare(DocumentDto o1, DocumentDto o2) {
return o1.getId().compareTo(o2.getId());
}
}
public class DocumentUserSort implements Comparator<DocumentDto> {
@Override
public int compare(DocumentDto o1, DocumentDto o2) {
return o1.getCreateUser().compareTo(o2.getCreateUser());
}
}
public class DocumentTypeSort implements Comparator<DocumentDto> {
@Override
public int compare(DocumentDto o1, DocumentDto o2) {
return o1.getDocumentType().getCode().compareTo(o2.getDocumentType().getCode());
}
}
Conclusion : this method isn't has efficient but you can create generic sort using a file configuration in this way.
Setup JAVA_OPTS as a system variable with the following content:
JAVA_OPTS="-Xms256m -Xmx512m"
After that in a command prompt run the following commands:
SET JAVA_OPTS="-Xms256m -Xmx512m"
This can be explained as follows:
These values should be changed according to application requirements.
EDIT:
You can also try adding it through the Environment Properties menu which can be found at:
EDIT 2:
JAVA_OPTS is a system variable that stores various settings/configurations for your local Java Virtual Machine. By having JAVA_OPTS set as a system variable all applications running on top of the JVM will take their settings from this parameter.
To setup a system variable you have to complete the steps listed above from 1 to 4.
Five Ways to Wire Up an Event Listener is a great article overviewing the various ways to set up a single event listener. Let me expand that here for multiple listeners.
public class main extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//attach an instance of HandleClick to the Button
HandleClick handleClick = new HandleClick();
findViewById(R.id.button1).setOnClickListener(handleClick);
findViewById(R.id.button2).setOnClickListener(handleClick);
}
private class HandleClick implements OnClickListener{
public void onClick(View view) {
switch(view.getId()) {
case R.id.button1:
// do stuff
break;
case R.id.button2:
// do stuff
break;
}
}
}
}
public class main extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViewById(R.id.button1).setOnClickListener(handleClick);
findViewById(R.id.button2).setOnClickListener(handleClick);
}
private OnClickListener handleClick = new OnClickListener() {
public void onClick(View view) {
switch (view.getId()) {
case R.id.button1:
// do stuff
break;
case R.id.button2:
// do stuff
break;
}
}
};
}
public class main extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
public void onClick(View view) {

});
findViewById(R.id.button2).setOnClickListener(new OnClickListener() {

And in xml:
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="HandleClick" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="HandleClick" />
Using TinyMCE editor, the only way I was able to remove all borders was to use border:hidden
in the style like this:
<style>
table, tr {border:hidden;}
td, th {border:hidden;}
</style>
And in the HTML like this:
<table style="border:hidden;"</table>

If you need more than one location, you need more than one task. One copy task can copy only from one location (including multiple files) to another one on the node.
- copy: src=/file1 dest=/destination/file1
- copy: src=/file2 dest=/destination/file2
# copy each file over that matches the given pattern
- copy: src={{ item }} dest=/destination/
with_fileglob:
- /files/*
Love VonC's answer. Here's an easy version of it for beginners.
There is a git remote called origin
which I am sure you are all aware of. Basically, you can add as many remotes to a git repo as you want. So, what we can do is introduce a new remote which is the original repo not the fork. I like to call it original
Let's add original repo's to our fork as a remote.
git remote add original https://git-repo/original/original.git
Now let's fetch the original repo to make sure we have the latest coded
git fetch original
As, VonC suggested, make sure we are on the master.
git checkout master
Now to bring our fork up to speed with the latest code on original repo, all we have to do is hard reset our master branch in accordance with the original remote.
git reset --hard original/master
And you are done :)
Have you tried Autodia yet? Last time I tried it it wasn't perfect, but it was good enough.
The solutions above didn't really work in my case. I couldn't use ArgumentCaptor as the method was called several times and I needed to validate each one. A simple Matcher with "argThat" did the trick easily.
Custom Matcher
// custom matcher
private class PolygonMatcher extends ArgumentMatcher<PolygonOptions> {
private int fillColor;
public PolygonMatcher(int fillColor) {
this.fillColor = fillColor;
}
@Override
public boolean matches(Object argument) {
if (!(argument instanceof PolygonOptions)) return false;
PolygonOptions arg = (PolygonOptions)argument;
return Color.red(arg.getFillColor()) == Color.red(fillColor)
&& Color.green(arg.getFillColor()) == Color.green(fillColor)
&& Color.blue(arg.getFillColor()) == Color.blue(fillColor);
}
}
Test Runner
// do setup work setup
// 3 light green polygons
int green = getContext().getResources().getColor(R.color.dmb_rx_bucket1);
verify(map, times(3)).addPolygon(argThat(new PolygonMatcher(green)));
// 1 medium yellow polygons
int yellow = getContext().getResources().getColor(R.color.dmb_rx_bucket4);
verify(map, times(1)).addPolygon(argThat(new PolygonMatcher(yellow)));
// 3 red polygons
int orange = getContext().getResources().getColor(R.color.dmb_rx_bucket5);
verify(map, times(3)).addPolygon(argThat(new PolygonMatcher(orange)));
// 2 red polygons
int red = getContext().getResources().getColor(R.color.dmb_rx_bucket7);
verify(map, times(2)).addPolygon(argThat(new PolygonMatcher(red)));
The default console handler is attached to the root logger, which is a parent of all other loggers including yours. So I see two ways to solve your problem:
If this is only affects this particular class of yours, the simplest solution would be to disable passing the logs up to the parent logger:
logger.setUseParentHandlers(false);
If you want to change this behaviour for your whole app, you could remove the default console handler from the root logger altogether before adding your own handlers:
Logger globalLogger = Logger.getLogger("global");
Handler[] handlers = globalLogger.getHandlers();
for(Handler handler : handlers) {
globalLogger.removeHandler(handler);
}
Note: if you want to use the same log handlers in other classes too, the best way is to move the log configuration into a config file in the long run.
I know people say you shouldn't use regular expressions to parse HTML, but in this case I find it perfectly fine.
$string = '<img border="0" src="/images/image.jpg" alt="Image" width="100" height="100" />';
preg_match('/<img(.*)src(.*)=(.*)"(.*)"/U', $string, $result);
$foo = array_pop($result);
string hex = "#FFFFFF";
Color _color = System.Drawing.ColorTranslator.FromHtml(hex);
Note: the hash is important!
An activity populates the ActionBar in its onCreateOptionsMenu()
method.
Instead of using setcustomview()
, just override onCreateOptionsMenu
like this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
return true;
}
If an actions in the ActionBar is selected, the onOptionsItemSelected()
method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menuitem1:
Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
break;
case R.id.menuitem2:
Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
break;
}
return true;
}
There are many scenarios where you want to commit a directory to your Git repo but without the files in it, for example the logs
, cache
, uploads
directories etc.
So what I always do is to add a .gitignore
file in those directories with the following content:
*
!.gitignore
With this .gitignore
file, Git will not track any files in those directories yet still allow me to add the .gitignore
file and hence the directory itself to the repo.
Running the command prompt or Powershell ISE as an administrator fixed this for me.
I also was not happy with the Internet checking options available (Why is this not a native API?!?!)
My own issue was with 100% packet loss -- when a device is connected to the router, but the router is not connected to the Internet. Reachability and others will hang for ages. I created a utility singleton class to deal with that by adding an asynch time-out. It works fine in my app. Hope it helps. Here's the link on github:
A general purpose way is to coerce the collation to DATABASE_DEFAULT. This removes hardcoding the collation name which could change.
It's also useful for temp table and table variables, and where you may not know the server collation (eg you are a vendor placing your system on the customer's server)
select
sone_field collate DATABASE_DEFAULT
from
table_1
inner join
table_2 on table_1.field collate DATABASE_DEFAULT = table_2.field
where whatever
In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as
save page as
filename : any_name.html
save as type : webpage complete.
Then you will get any_name.html
and any_name folder
.
If you are looking to create an instant messenger for Android, this code should get you started somewhere.
Excerpt from the source :
This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.
EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.
There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!
*UPDATE : * Scringo services will be closed down on 15 February, 2015.
To expand on the answer by bradtgmurray, you may want to make one exception to the pure virtual method list of your interface by adding a virtual destructor. This allows you to pass pointer ownership to another party without exposing the concrete derived class. The destructor doesn't have to do anything, because the interface doesn't have any concrete members. It might seem contradictory to define a function as both virtual and inline, but trust me - it isn't.
class IDemo
{
public:
virtual ~IDemo() {}
virtual void OverrideMe() = 0;
};
class Parent
{
public:
virtual ~Parent();
};
class Child : public Parent, public IDemo
{
public:
virtual void OverrideMe()
{
//do stuff
}
};
You don't have to include a body for the virtual destructor - it turns out some compilers have trouble optimizing an empty destructor and you're better off using the default.
Font.PLAIN is not an enum. It is just an int
. If you need to take the value out of an enum, you can't avoid calling a method or using a .value
, because enums are actually objects of its own type, not primitives.
If you truly only need an int
, and you are already to accept that type-safety is lost the user may pass invalid values to your API, you may define those constants as int
also:
public final class DownloadType {
public static final int AUDIO = 0;
public static final int VIDEO = 1;
public static final int AUDIO_AND_VIDEO = 2;
// If you have only static members and want to simulate a static
// class in Java, then you can make the constructor private.
private DownloadType() {}
}
By the way, the value
field is actually redundant because there is also an .ordinal()
method, so you could define the enum
as:
enum DownloadType { AUDIO, VIDEO, AUDIO_AND_VIDEO }
and get the "value" using
DownloadType.AUDIO_AND_VIDEO.ordinal()
Edit: Corrected the code.. static class
is not allowed in Java. See this SO answer with explanation and details on how to define static classes in Java.
public class Arr {
public static void main(String[] args) {
// TODO Auto-generated method stub
int a[] = {1,2,3};
//let a[] is your original array
System.out.println(a[0] + " " + a[1] + " " + a[2]);
int b[];
//let b[] is your temporary array with size greater than a[]
//I have took 5
b = new int[5];
//now assign all a[] values to b[]
for(int i = 0 ; i < a.length ; i ++)
b[i] = a[i];
//add next index values to b
b[3] = 4;
b[4] = 5;
//now assign b[] to a[]
a = b;
//now you can heck that size of an original array increased
System.out.println(a[0] + " " + a[1] + " " + a[2] + " " + a[3] + " "
+ a[4]);
}
}
Output for the above code is:
1 2 3
1 2 3 4 5
var svg = d3.select("body")
.append("svg")
.style("width", 200)
.style("height", 100)
Firstly, as @l33tnerd said, f.close
should be outside the for loop.
Secondly, you are only calling readline
once, before the loop. That only reads the first line. The trick is that in Python, files act as iterators, so you can iterate over the file without having to call any methods on it, and that will give you one line per iteration:
if data.find('!masters') != -1:
f = open('masters.txt')
for line in f:
print line,
sck.send('PRIVMSG ' + chan + " " + line)
f.close()
Finally, you were referring to the variable lines
inside the loop; I assume you meant to refer to line
.
Edit: Oh and you need to indent the contents of the if
statement.
@Gajus Kuizinas and @CodeHater are correct. Here i am just giving an example. While we are working with ng-if, if the assigned value is false then the whole html elements will be removed from DOM. and if assigned value is true, then the html elements will be visible on the DOM. And the scope will be different compared to the parent scope. But in case of ng-show, it wil just show and hide the elements based on the assigned value. But it always stays in the DOM. Only the visibility changes as per the assigned value.
http://plnkr.co/edit/3G0V9ivUzzc8kpLb1OQn?p=preview
Hope this example will help you in understanding the scopes. Try giving false values to ng-show and ng-if and check the DOM in console. Try entering the values in the input boxes and observe the difference.
<!DOCTYPE html>
<input type="text" ng-model="data">
<div ng-show="true">
<br/>ng-show=true :: <br/><input type="text" ng-model="data">
</div>
<div ng-if="true">
<br/>ng-if=true :: <br/><input type="text" ng-model="data">
</div>
{{data}}
try this.
^(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)\d\d$

To execute more Maven builds from one script you shall use the Windows call function in the following way:
call mvn install:install-file -DgroupId=gdata -DartifactId=base -Dversion=1.0 -Dfile=gdata-base-1.0.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=gdata -DartifactId=blogger -Dversion=2.0 -Dfile=gdata-blogger-2.0.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=gdata -DartifactId=blogger-meta -Dversion=2.0 -Dfile=gdata-blogger-meta-2.0.jar -Dpackaging=jar -DgeneratePom=true
The best way to do this is to set display: inline;
. Note, however, that in inline display, you lose access to some layout properties, such as manual height and vertical margins, but this doesn't appear to be a problem for your page.

If you have an ES2015 environment (as of this writing: io.js, IE11, Chrome, Firefox, WebKit nightly), then the following will work, and will be fast (viz. O(n)):
function hasDuplicates(array) {
return (new Set(array)).size !== array.length;
}
If you only need string values in the array, the following will work:
function hasDuplicates(array) {
var valuesSoFar = Object.create(null);
for (var i = 0; i < array.length; ++i) {
var value = array[i];
if (value in valuesSoFar) {
return true;
}
valuesSoFar[value] = true;
}
return false;
}
We use a "hash table" valuesSoFar
whose keys are the values we've seen in the array so far. We do a lookup using in
to see if that value has been spotted already; if so, we bail out of the loop and return true
.
If you need a function that works for more than just string values, the following will work, but isn't as performant; it's O(n2) instead of O(n).
function hasDuplicates(array) {
var valuesSoFar = [];
for (var i = 0; i < array.length; ++i) {
var value = array[i];
if (valuesSoFar.indexOf(value) !== -1) {
return true;
}
valuesSoFar.push(value);
}
return false;
}
The difference is simply that we use an array instead of a hash table for valuesSoFar
, since JavaScript "hash tables" (i.e. objects) only have string keys. This means we lose the O(1) lookup time of in
, instead getting an O(n) lookup time of indexOf
.
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
If you want to use the same function on different events the following code block can be used
$('input').on('keyup blur focus', function () {
//function block
})
for ($s=65; $s<=90; $s++) {
//echo chr($s);
$objPHPExcel->getActiveSheet()->getColumnDimension(chr($s))->setAutoSize(true);
}
The children of a row-flexbox container automatically fill the container's vertical space.

There's some joking, and misleading comments, even partially incorrect information in the answers here. I'd like to try to improve on them:
First, as some have pointed out, you have a bug in your code that relates to the question:
if ($status = 'clear' AND $pRent == 0)
should be (note the ==
instead of =
in the first part):
if ($status == 'clear' AND $pRent == 0)
which in this case is functionally equivalent to
if ($status == 'clear' && $pRent == 0)
Second, note that these operators (and or && ||
) are short-circuit operators. That means if the answer can be determined with certainty from the first expression, the second one is never evaluated. Again this doesn't matter for your debugged line above, but it is extremely important when you are combining these operators with assignments, because
Third, the real difference between and or
and && ||
is their operator precedence. Specifically the importance is that && ||
have higher precedence than the assignment operators (= += -= *= **= /= .= %= &= |= ^= <<= >>=
) while and or
have lower precendence than the assignment operators. Thus in a statement that combines the use of assignment and logical evaluation it matters which one you choose.
Modified examples from PHP's page on logical operators:
$e = false || true;
will evaluate to true
and assign that value to $e
, because ||
has higher operator precedence than =
, and therefore it essentially evaluates like this:
$e = (false || true);
however
$e = false or true;
will assign false
to $e
(and then perform the or
operation and evaluate true
) because =
has higher operator precedence than or
, essentially evaluating like this:
($e = false) or true;
The fact that this ambiguity even exists makes a lot of programmers just always use && ||
and then everything works clearly as one would expect in a language like C, ie. logical operations first, then assignment.
Some languages like Perl use this kind of construct frequently in a format similar to this:
$connection = database_connect($parameters) or die("Unable to connect to DB.");
This would theoretically assign the database connection to $connection
, or if that failed (and we're assuming here the function would return something that evalues to false
in that case), it will end the script with an error message. Because of short-circuiting, if the database connection succeeds, the die()
is never evaluated.
Some languages that allow for this construct straight out forbid assignments in conditional/logical statements (like Python) to remove the amiguity the other way round.
PHP went with allowing both, so you just have to learn about your two options once and then code how you'd like, but hopefully you'll be consistent one way or another.
Whenever in doubt, just throw in an extra set of parenthesis, which removes all ambiguity. These will always be the same:
$e = (false || true);
$e = (false or true);
Armed with all that knowledge, I prefer using and or
because I feel that it makes the code more readable. I just have a rule not to combine assignments with logical evaluations. But at that point it's just a preference, and consistency matters a lot more here than which side you choose.
A matrix is really just a vector with a dim
attribute (for the dimensions). So you can add dimensions to vec
using the dim()
function and vec
will then be a matrix:
vec <- 1:49
dim(vec) <- c(7, 7) ## (rows, cols)
vec
> vec <- 1:49
> dim(vec) <- c(7, 7) ## (rows, cols)
> vec

First of all you need to differentiate between the MySQL as Server, MySQL as Client and the Ruby bindings to MySQL.
I'm not familiar with Mac, but for *nix OS you need to install MySQL through your package manager. To get the Ruby bindings installed with
gem install mysql
you need the development headers of ruby (in Ubuntu it is the package ruby-dev) and the development headers of the MySQL-Client (currently libmysqlclient16-dev
in Ubuntu). I don't know if they are named different on Mac, but after you got those installed the Ruby bindings should install without any error.
CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.
Using WIN + Q worked for me. Just q alone gave me "command not found" and eventually it jumped back into the git diff insanity.
.NET is not very helpful, but you can try the following algorithm:
Here is the call:
