this may be old, but for those looking for answer you can use this...
public void stopHandler() {
handler.removeMessages(0);

Adding an answer that exclusively uses the pandas library to read in a .csv file and save as a .xlsx file. This example makes use of pandas.read_csv
(Link to docs) and pandas.dataframe.to_excel
(Link to docs).
The fully reproducible example uses numpy to generate random numbers only, and this can be removed if you would like to use your own .csv file.
import pandas as pd
import numpy as np
# Creating a dataframe and saving as test.csv in current directory
df = pd.DataFrame(np.random.randn(100000, 3), columns=list('ABC'))
df.to_csv('test.csv', index = False)
# Reading in test.csv and saving as test.xlsx
df_new = pd.read_csv('test.csv')
writer = pd.ExcelWriter('test.xlsx')
df_new.to_excel(writer, index = False)
writer.save()
also check this out, for example we wanna count t
echo "test" | awk -v RS='t' 'END{print NR-1}'
or in python
python -c 'print "this is for test".count("t")'
or even better, we can make our script dynamic with awk
echo 'test' | awk '{for (i=1 ; i<=NF ; i++) array[$i]++ } END{ for (char in array) print char,array[char]}' FS=""
in this case output is like this :
e 1
s 1
t 2
Enums are the recommended way to provide easy-to-remember names for a defined set of contants (optionally with some limited behaviour too).
You should use enums where otherwise you would use multiple static integer constants (eg. public static int ROLE_ADMIN = 0
or BLOOD_TYPE_AB = 2
)
The main advantages of using enums instead of these are type safety, compile type warnings/errors when trying to use wrong values and providing a namespace for related "constants". Additionally they are easier to use within an IDE since it helps code completion too.
Simply do:
grouped_df = df.groupby('A')
for key, item in grouped_df:
print(grouped_df.get_group(key), "\n\n")
This also works,
grouped_df = df.groupby('A')
gb = grouped_df.groups
for key, values in gb.iteritems():
print(df.ix[values], "\n\n")
For selective key grouping: Insert the keys you want inside the key_list_from_gb
, in following, using gb.keys()
: For Example,
gb = grouped_df.groups
gb.keys()
key_list_from_gb = [key1, key2, key3]
for key, values in gb.items():
if key in key_list_from_gb:
print(df.ix[values], "\n")
If $_SERVER['HTTP_REFERER']
variable doesn't seems to work, then you can either use Google Analytics or AddThis Analytics.
Morgan :- Morgan is a middleware which will help us to identify the clients who are accessing our application. Basically a logger.
To Use Morgan, We need to follow below steps :-
npm install --save morgan
This will add morgan to json.package file
var morgan = require('morgan');
3> // create a write stream (in append mode)
var accessLogStream = fs.createWriteStream(
path.join(__dirname, 'access.log'), {flags: 'a'}
);
// setup the logger
app.use(morgan('combined', {stream: accessLogStream}));
Note: Make sure you do not plumb above blindly make sure you have every conditions where you need .
Above will automatically create a access.log file to your root once user will access your app.
I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray()
According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.
This will work for you:
$phpExcel = new PHPExcel();
$styleArray = array(
'font' => array(
'bold' => true,
'color' => array('rgb' => 'FF0000'),
'size' => 15,
'name' => 'Verdana'
));
$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);
To apply font style to complete excel document:
$styleArray = array(
'font' => array(
'bold' => true,
'color' => array('rgb' => 'FF0000'),
'size' => 15,
'name' => 'Verdana'
));
$phpExcel->getDefaultStyle()
->applyFromArray($styleArray);
If you want to fetch + merge, run
git pull
if you want simply to fetch :
git fetch
Try this:
SELECT s.NAME + '.' + t.NAME AS TableName
FROM sys.tables t
INNER JOIN sys.schemas s
ON t.schema_id = s.schema_id
it will display the schema+table name for all tables in the current database.
Here is a version that will list every table in every database on the current server. it allows a search parameter to be used on any part or parts of the server+database+schema+table names:
SET NOCOUNT ON
DECLARE @AllTables table (CompleteTableName nvarchar(4000))
DECLARE @Search nvarchar(4000)
,@SQL nvarchar(4000)
SET @Search=null --all rows
SET @SQL='select @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id WHERE @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name LIKE ''%'+ISNULL(@SEARCH,'')+'%'''
INSERT INTO @AllTables (CompleteTableName)
EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY 1
set @Search to NULL for all tables, set it to things like 'dbo.users' or 'users' or '.master.dbo' or even include wildcards like '.master.%.u', etc.
If anyone came here from python-graphql client looking for a solution to pass an object as variable here's what I used:
query = """
{{
pairs(block: {block} first: 200, orderBy: trackedReserveETH, orderDirection: desc) {{
id
txCount
reserveUSD
trackedReserveETH
volumeUSD
}}
}}
""".format(block=''.join(['{number: ', str(block), '}']))
query = gql(query)
Make sure to escape all curly braces like I did: "{{", "}}"
If you don't mind processing them immediately, I like to do this:
for i in $(echo $IN | tr ";" "\n")
do
# process
done
You could use this kind of loop to initialize an array, but there's probably an easier way to do it. Hope this helps, though.
Unfortunately, that's not an Angular2 error, that's an error your browser is running into (i.e. outside of your app).
That CORS header will have to be added to that endpoint on the server before you can make ANY requests.
In IntelliJ Idea 2019 you can find scope "Problems" under the "Project" view. Default scope is "Project".
As of Xcode 10+, and according to the WWDC 2018 session 223, "Embracing Algorithms," a good method going forward will be mutating func removeAll(where predicate: (Element) throws -> Bool) rethrows
Apple's example:
var phrase = "The rain in Spain stays mainly in the plain."
let vowels: Set<Character> = ["a", "e", "i", "o", "u"]
phrase.removeAll(where: { vowels.contains($0) })
// phrase == "Th rn n Spn stys mnly n th pln."
So in the OP's example, removing animals[2], "chimps":
var animals = ["cats", "dogs", "chimps", "moose"]
animals.removeAll(where: { $0 == "chimps" } )
// or animals.removeAll { $0 == "chimps" }
This method may be preferred because it scales well (linear vs quadratic), is readable and clean. Keep in mind that it only works in Xcode 10+, and as of writing this is in Beta.
The String#replaceAll()
interprets the argument as a regular expression. The \
is an escape character in both String
and regex
. You need to double-escape it for regex:
string.replaceAll("\\\\", "\\\\\\\\");
But you don't necessarily need regex for this, simply because you want an exact character-by-character replacement and you don't need patterns here. So String#replace()
should suffice:
string.replace("\\", "\\\\");
Update: as per the comments, you appear to want to use the string in JavaScript context. You'd perhaps better use StringEscapeUtils#escapeEcmaScript()
instead to cover more characters.
I had the same problem, and found that the solution was to add the android:tools to the first node. In my case it is a LineraLayout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
Another option could be using automapper: You will be converting to any type from your anonymous returned object as long public properties matches. The key points are, returning object, use linq and autommaper. (or use similar idea returning serialized json, etc. or use reflection..)

using System.Reflection;
using AutoMapper;

I know I'm late on this (it's been two years since the question was asked) but I accomplished this by intercepting the back button press. Rather than checking for specific activities, I just look at the count and if it's less than 3 it simply sends the app to the back (pausing the app and returning the user to whatever was running before launch). I check for less than three because I only have one intro screen. Also, I check the count because my app allows the user to navigate back to the home screen through the menu, so this allows them to back up through other screens like normal if there are activities other than the intro screen on the stack.
//We want the home screen to behave like the bottom of the activity stack so we do not return to the initial screen
//unless the application has been killed. Users can toggle the session mode with a menu item at all other times.
@Override
public void onBackPressed() {
//Check the activity stack and see if it's more than two deep (initial screen and home screen)
//If it's more than two deep, then let the app proccess the press
ActivityManager am = (ActivityManager)this.getSystemService(Activity.ACTIVITY_SERVICE);
List<RunningTaskInfo> tasks = am.getRunningTasks(3); //3 because we have to give it something. This is an arbitrary number
int activityCount = tasks.get(0).numActivities;
if (activityCount < 3)
{
moveTaskToBack(true);
}
else
{
super.onBackPressed();
}
}
I know this question is a couple years old, but I am surprised to find that no one suggested:
text-align: center;
this is a more universal property than justify-content, and is definitely not unique to grid, but I find that when dealing with text, which is what this question specifically asks about, that it aligns text to the center with-out affecting the space between grid items, or the vertical centering. It centers text horizontally where its stands on its vertical axis. I also find it to remove a layer of complexity that justify-content and align-items adds. justify-content and align-items affects the entire grid item or items, text-align centers the text without affecting the container it is in. Hope this helps.
@andresh For me locationChangeSuccess worked instead of routeChangeSuccess.
//Go back to the previous stage with this back() call
var history = [];
$rootScope.$on('$locationChangeSuccess', function() {
history.push($location.$$path);
});
$rootScope.back = function () {
var prevUrl = history.length > 1 ? history.splice(-2)[0] : "/";
$location.path(prevUrl);
history = []; //Delete history array after going back
};
I am using large data sets exported to a python file in the form
XVals1 = [.........]
XVals2 = [.........]
Each list is of identical length. I use
>>> a1 = np.array(SV.XVals1)
>>> a2 = np.array(SV.XVals2)
Then
>>> A = np.matrix([a1,a2])
use this code to redirect the page
echo "<script>alert('There are no fields to generate a report');document.location='admin/ahm/panel'</script>";
Yor $.post
has no data. You need to pass the form data. You can use serialize()
to post the form data. Try this
$("#post-btn").click(function(){
$.post("process.php", $('#reg-form').serialize() ,function(data){
alert(data);
});
});
Assuming you are calling this in an Activity class
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image);
The first parameter, Resources, is required. It is normally obtainable in any Context (and subclasses like Activity).
I believe the way to do this is $location.url('/RouteTo/Login');
Edit for Clarity
Say my route for my login view was /Login
, I would say $location.url('/Login')
to navigate to that route.
For locations outside of the Angular app (i.e. no route defined), plain old JavaScript will serve:
window.location = "http://www.my-domain.com/login"
This worked:
$("#theSelectId").prepend("<option value='' selected='selected'></option>");
Firebug Output:
<select id="theSelectId">
<option selected="selected" value=""/>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
You could also use .prependTo
if you wanted to reverse the order:
?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

Many ways to skin this cat. I put a simple function in each table's package...
function exists( id_in in yourTable.id%type ) return boolean is
res boolean := false;
begin
for c1 in ( select 1 from yourTable where id = id_in and rownum = 1 ) loop
res := true;
exit; -- only care about one record, so exit.
end loop;
return( res );
end exists;
Makes your checks really clean...
IF pkg.exists(someId) THEN
...
ELSE

END IF;
Cern's ROOT produces some pretty nice stuff, I use it to display Neural Network data a lot.
I believe some of the respondents of this question have missed the broader implication of the fold
function as an abstract tool. Yes, sum
can do the same thing for a list of integers, but this is a trivial case. fold
is more generic. It is useful when you have a sequence of data structures of varying shape and want to cleanly express an aggregation. So instead of having to build up a for
loop with an aggregate variable and manually recompute it each time, a fold
function (or the Python version, which reduce
appears to correspond to) allows the programmer to express the intent of the aggregation much more plainly by simply providing two things:
/<b>(.*?)<\/b>/g
Add g
(global) flag after:
/<b>(.*?)<\/b>/g.exec(str)
//^-----here it is
However if you want to get all matched elements, then you need something like this:
var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";
var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"]
If an element has attributes, regexp will be:
/<b [^>]+>(.*?)<\/b>/g.exec(str)
The difference is pretty subtle and if you dont pay much attention then you will keep it using in a wrong way.
Best way to understand the difference between orElse()
and orElseGet()
is that orElse()
will always be executed if the Optional<T>
is null or not, But orElseGet()
will only be executed when Optional<T>
is null.
The dictionary meaning of orElse is :- execute the part when something is not present, but here it contradicts, see the below example:
Optional<String> nonEmptyOptional = Optional.of("Vishwa Ratna");
String value = nonEmptyOptional.orElse(iAmStillExecuted());
public static String iAmStillExecuted(){
System.out.println("nonEmptyOptional is not NULL,still I am being executed");
return "I got executed";
}
Output: nonEmptyOptional is not NULL,still I am being executed
Optional<String> emptyOptional = Optional.ofNullable(null);
String value = emptyOptional.orElse(iAmStillExecuted());
public static String iAmStillExecuted(){
System.out.println("emptyOptional is NULL, I am being executed, it is normal as
per dictionary");
return "I got executed";
}
Output: emptyOptional is NULL, I am being executed, it is normal as per dictionary
For
orElseGet()
, The method goes as per dictionary meaning, TheorElseGet()
part will be executed only when the Optional is null.
Benchmarks:
+--------------------+------+-----+------------+-------------+-------+
| Benchmark | Mode | Cnt | Score | Error | Units |
+--------------------+------+-----+------------+-------------+-------+
| orElseBenchmark | avgt | 20 | 60934.425 | ± 15115.599 | ns/op |
+--------------------+------+-----+------------+-------------+-------+
| orElseGetBenchmark | avgt | 20 | 3.798 | ± 0.030 | ns/op |
+--------------------+------+-----+------------+-------------+-------+
Remarks:
orElseGet()
has clearly outperformedorElse()
for our particular example.
Hope it clears the doubts of people like me who wants the very basic ground example :)
In C, int
, char
, long
, etc. are all integers.
They typically have different memory sizes and thus different ranges as in INT_MIN
to INT_MAX
. char
and arrays of char
are often used to store characters and strings. Integers are stored in many types: int
being the most popular for a balance of speed, size and range.
ASCII is by far the most popular character encoding, but others exist. The ASCII code for an 'A' is 65, 'a' is 97, '\n' is 10, etc. ASCII data is most often stored in a char
variable. If the C environment is using ASCII encoding, the following all store the same value into the integer variable.
int i1 = 'a';
int i2 = 97;
char c1 = 'a';
char c2 = 97;
To convert an int
to a char
, simple assign:
int i3 = 'b';
int i4 = i3;
char c3;
char c4;
c3 = i3;
// To avoid a potential compiler warning, use a cast `char`.
c4 = (char) i4;
This warning comes up because int
typically has a greater range than char
and so some loss-of-information may occur. By using the cast (char)
, the potential loss of info is explicitly directed.
To print the value of an integer:
printf("<%c>\n", c3); // prints <b>
// Printing a `char` as an integer is less common but do-able
printf("<%d>\n", c3); // prints <98>
// Printing an `int` as a character is less common but do-able.
// The value is converted to an `unsigned char` and then printed.
printf("<%c>\n", i3); // prints <b>
printf("<%d>\n", i3); // prints <98>
There are additional issues about printing such as using %hhu
or casting when printing an unsigned char
, but leave that for later. There is a lot to printf()
.
return false
from within a jQuery event handler is effectively the same as calling both e.preventDefault
and e.stopPropagation
on the passed jQuery.Event object.
e.preventDefault()
will prevent the default event from occuring, e.stopPropagation()
will prevent the event from bubbling up and return false
will do both. Note that this behaviour differs from normal (non-jQuery) event handlers, in which, notably, return false
does not stop the event from bubbling up.
Source: John Resig
Any benefit to using event.preventDefault() over "return false" to cancel out an href click?
Better way is to use Queue class: http://docs.python.org/library/queue.html
Look at the good example code in the bottom of documentation page:
def worker():
while True:
item = q.get()
do_work(item)
q.task_done()
q = Queue()
for i in range(num_worker_threads):
t = Thread(target=worker)
t.daemon = True
t.start()
for item in source():
q.put(item)
q.join() # block until all tasks are done
I would start with upgrade of CMAKE version.
You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries
INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)
note that lib1
is expanded to liblib1.so
(on Linux), so use ln to create appropriate links in case you do not have them
Having read the above answers i found that for my situation the following fixed the issue.
This threw the error
myButton.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
MyDialogue dialog = new MyDialogue(getApplicationContext());
dialog.show();
}
});
Based on the previous answers that suggested the context was the wrong one, i changed the getApplicationContext() to retrieve the context from the View passed in to the buttons onClick method.
myButton.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
MyDialogue dialog = new MyDialogue(v.getContext());
dialog.show();
}
});
I don't fully understand the workings of Java so i could be wrong, but I'm guessing that for my specific situation the cause could have been related to the fact that the above snippet was defined in an Abstract Activity class; inherited and used by many Activities, perhaps that contributed to the fact that getApplicationContext() doesn't return a valid context?? (Just a guess).
You can access the Axes instance (ax
) with plt.gca()
. In this case, you can use
plt.gca().legend()
You can do this either by using the label=
keyword in each of your plt.plot()
calls or by assigning your labels as a tuple or list within legend
, as in this working example:
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(-0.75,1,100)
y0 = np.exp(2 + 3*x - 7*x**3)
y1 = 7-4*np.sin(4*x)
plt.plot(x,y0,x,y1)
plt.gca().legend(('y0','y1'))
plt.show()
However, if you need to access the Axes instance more that once, I do recommend saving it to the variable ax
with
ax = plt.gca()
and then calling ax
instead of plt.gca()
.
Just use the -jrm
option to remove the file and directory
structures
zip -jrm /path/to/file.zip /path/to/file
The file extension tells you how the image is saved. Some of those formats just save the bits as they are, some compress the image in different ways, including lossless and lossy methods. The Web can tell you, although I know some of the patient responders will outline them here.
The web favors gif, jpg, and png, mostly. JPEG is the same (or very close) to jpg.
you may also place the followinng
<a href='javascript:alert("hello world!");'>Click me</a>
to your html-code, and when you click on 'Click me' hyperlink, javascript will appear in url-bar and Alert dialog will show
Since security.disable option is banned from usage there is still a way to achieve it from pure config without touching any class flies (for me it creates convenience with environments manipulation and possibility to activate it with ENV variable) if you use Boot
spring.autoconfigure.exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
You don't want git revert
. That undoes a previous commit. You want git checkout
to get git's version of the file from master.
git checkout -- filename.txt
In general, when you want to perform a git operation on a single file, use -- filename

Git introduced a new command git restore
in version 2.23.0
. Therefore, if you have git version 2.23.0+
, you can simply git restore filename.txt
- which does the same thing as git checkout -- filename.txt
. The docs for this command do note that it is currently experimental.
Setting Up the database
public class DatabaseHelper extends SQLiteOpenHelper {
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "database_name";
// Table Names
private static final String DB_TABLE = "table_image";
// column names
private static final String KEY_NAME = "image_name";
private static final String KEY_IMAGE = "image_data";
// Table create statement
private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+
KEY_NAME + " TEXT," +
KEY_IMAGE + " BLOB);";
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
// creating table
db.execSQL(CREATE_TABLE_IMAGE);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// on upgrade drop older tables
db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);
// create new table
onCreate(db);
}
}
Insert in the Database:
public void addEntry( String name, byte[] image) throws SQLiteException{
SQLiteDatabase database = this.getWritableDatabase();
ContentValues cv = new ContentValues();
cv.put(KEY_NAME, name);
cv.put(KEY_IMAGE, image);
database.insert( DB_TABLE, null, cv );
}
Retrieving data:
byte[] image = cursor.getBlob(1);
Note:
Below is an Utility class which I hope could help you:
public class DbBitmapUtility {
// convert from bitmap to byte array
public static byte[] getBytes(Bitmap bitmap) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0, stream);
return stream.toByteArray();
}
// convert from byte array to bitmap
public static Bitmap getImage(byte[] image) {
return BitmapFactory.decodeByteArray(image, 0, image.length);
}
}

If you are not familiar how to insert and retrieve into a database, go through this tutorial.
There are three method to pass value in php.
These three method are used for different purpose.For example if we want to receive our value on next page then we can use 'post' ($_POST) method as:-
$a=$_POST['field-name'];
If we require the value of variable on more than one page than we can use session variable as:-
$a=$_SESSION['field-name];
Before using this Syntax for creating SESSION variable we first have to add this tag at the very beginning of our php page
session_start();
GET method are generally used to print data on same page which used to take input from user. Its syntax is as:
$a=$_GET['field-name'];
POST method are generally consume more secure than GET because when we use Get method than it can display the data in URL bar.If the data is more sensitive data like password then it can be inggeris.
Since Apache library is deprecated, for those who want to use HttpURLConncetion
, I wrote this class to send Get and Post Request with the help of this answer:
public class WebService {
static final String COOKIES_HEADER = "Set-Cookie";
static final String COOKIE = "Cookie";
static CookieManager msCookieManager = new CookieManager();
private static int responseCode;
public static String sendPost(String requestURL, String urlParameters) {

String response = "";

url = new URL(requestURL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(15000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json; charset=utf-8");
if (msCookieManager.getCookieStore().getCookies().size() > 0) {
//While joining the Cookies, use ',' or ';' as needed. Most of the server are using ';'
conn.setRequestProperty(COOKIE ,
TextUtils.join(";", msCookieManager.getCookieStore().getCookies()));
}
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
if (urlParameters != null) {
writer.write(urlParameters);
}
writer.flush();
writer.close();
os.close();
Map<String, List<String>> headerFields = conn.getHeaderFields();
List<String> cookiesHeader = headerFields.get(COOKIES_HEADER);
if (cookiesHeader != null) {
for (String cookie : cookiesHeader) {
msCookieManager.getCookieStore().add(null, HttpCookie.parse(cookie).get(0));
}
}
setResponseCode(conn.getResponseCode());
if (getResponseCode() == HttpsURLConnection.HTTP_OK) {
String line;
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = br.readLine()) != null) {
response += line;
}
} else {
response = "";
}
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
// HTTP GET request
public static String sendGet(String url) throws Exception {
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// optional default is GET
con.setRequestMethod("GET");
//add request header
con.setRequestProperty("User-Agent", "Mozilla");

}
}
int responseCode = con.getResponseCode();
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}

return response.toString();

Not really - the background image is bounded by the element it's applied to, and the overflow properties only apply to the content (i.e. markup) within an element.
You can add another div into your footer div and apply the background image to that, though, and have that overflow instead.
Another good approach not mentioned in other posts is to use PropertyOverrideConfigurer in case you just want to override properties of some beans.
For example if you want to override the datasource for testing (i.e. use an in-memory database) in another xml config, you just need to use <context:property-override ..."/>
in new config and a .properties
file containing key-values taking the format beanName.property=newvalue
overriding the main props.
application-mainConfig.xml:
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource"
p:driverClassName="org.postgresql.Driver"
p:url="jdbc:postgresql://localhost:5432/MyAppDB"
p:username="myusername"
p:password="mypassword"
destroy-method="close" />
application-testConfig.xml:
<import resource="classpath:path/to/file/application-mainConfig.xml"/>
<!-- override bean props -->
<context:property-override location="classpath:path/to/file/beanOverride.properties"/>
beanOverride.properties:
dataSource.driverClassName=org.h2.Driver
dataSource.url=jdbc:h2:mem:MyTestDB
If you want to filter only items that are less than 7 days old then you just use
Filter
Created
is greater than or equal to
[Today]-7
Note - the screenshot is incorrect.
[Today] is fully supported in view filters in 2007 and onwards (just keep the spaces out!) and you only need to muck around with calculated columns in 2003.
I won't write your code but what you looking for is something like a jquery dialog
take a look here
$(function() {
$( "#dialog-confirm" ).dialog({
resizable: false,
height:140,
modal: true,
buttons: {
"Delete all items": function() {
$( this ).dialog( "close" );
},
Cancel: function() {
$( this ).dialog( "close" );
}
}
});
});
<div id="dialog-confirm" title="Empty the recycle bin?">
<p>
<span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>
These items will be permanently deleted and cannot be recovered. Are you sure?
</p>
</div>
In my case I did put Podfile.lock & Manifest.lock in source control, but I forgot to add Pods-Project.debug(release).xcconfig files to source control (by mistakenly adding *.xcconfig to .gitignore), then I got the same compile errors with exactly the same reason, PODS_ROOT is not being set.
So if the goal is that after cloning the repo, the project can immediately build and run, without having CocoaPods installed on the machine, you either add entire Pods directory in source control or add Podfile.lock, Manifest.lock, project's xcconfig files and Pods xcconfig files to source control.
I didn't put the private .xcconfig that merges the build settings with the default CocoaPods configuration to source control.
If you use array_merge
, this will reindex the keys. The manual states:
Values in the input array with numeric keys will be renumbered with incrementing keys starting from zero in the result array.
http://php.net/manual/en/function.array-merge.php
This is where i found the original answer.
http://board.phpbuilder.com/showthread.php?10299961-Reset-index-on-array-after-unset()
Note: This solution works only with Github Desktop GUI.
By using Github Desktop GUI it is very simple.
Move the folder onto another location (to out of the project folder) temporarily.
Edit your .gitignore
file and remove the folder entry which would be remove master repository on the github page.
Commit and Sync the project folder.
Re-move the folder into the project folder
Re-edit .gitignore
file.
That's all.
You also need to include the Log4J JAR file in the classpath.
Note that slf4j-log4j12-1.6.4.jar
is only an adapter to make it possible to use Log4J via the SLF4J API. It does not contain the actual implementation of Log4J.
If having the directory already exist is not a problem for you, you could just redirect stderr for that command, getting rid of the error message:
-mkdir $(OBJDIR) 2>/dev/null
Make sure to also add "C:\Python27\Scripts" to your path. pip.exe should be in that folder. Then you can just run:
C:\> pip install modulename
You can implement a system that handles the type checks automatically, using a wrapper in your function.
With this approach, you can build a complete
declarative type check system
that will manage for you the type checks . If you are interested in taking a more in depth look at this concept, check the Functyped library
The following implementation illustrates the main idea, in a simplistic, but operative way :
/*_x000D_
* checkType() : Test the type of the value. If succeds return true, _x000D_
* if fails, throw an Error_x000D_
*/_x000D_
function checkType(value,type, i){_x000D_
// perform the appropiate test to the passed _x000D_
// value according to the provided type_x000D_
switch(type){_x000D_
case Boolean : _x000D_
if(typeof value === 'boolean') return true;_x000D_
break;_x000D_
case String : _x000D_
if(typeof value === 'string') return true;_x000D_
break;_x000D_
case Number : _x000D_
if(typeof value === 'number') return true;_x000D_
break;_x000D_
default :_x000D_
throw new Error(`TypeError : Unknown type provided in argument ${i+1}`);_x000D_
}_x000D_
// test didn't succeed , throw error_x000D_
throw new Error(`TypeError : Expecting a ${type.name} in argument ${i+1}`);_x000D_
}_x000D_
_x000D_
_x000D_
/*_x000D_
* typedFunction() : Constructor that returns a wrapper_x000D_
* to handle each function call, performing automatic _x000D_
* arguments type checking_x000D_
*/_x000D_
function typedFunction( parameterTypes, func ){_x000D_
// types definitions and function parameters _x000D_
// count must match_x000D_
if(parameterTypes.length !== func.length) throw new Error(`Function has ${func.length} arguments, but type definition has ${parameterTypes.length}`);_x000D_
// return the wrapper..._x000D_
return function(...args){_x000D_
// provided arguments count must match types_x000D_
// definitions count_x000D_
if(parameterTypes.length !== args.length) throw new Error(`Function expects ${func.length} arguments, instead ${args.length} found.`);_x000D_
// iterate each argument value, and perform a_x000D_
// type check against it, using the type definitions_x000D_
// provided in the construction stage_x000D_
for(let i=0; i<args.length;i++) checkType( args[i], parameterTypes[i] , i)_x000D_
// if no error has been thrown, type check succeed_x000D_
// execute function!_x000D_
return func(...args);_x000D_
}_x000D_
}_x000D_
_x000D_
// Play time! _x000D_
// Declare a function that expects 2 Numbers_x000D_
let myFunc = typedFunction( [ Number, Number ], (a,b)=>{_x000D_
return a+b;_x000D_
});_x000D_
_x000D_
// call the function, with an invalid second argument_x000D_
myFunc(123, '456')_x000D_
// ERROR! Uncaught Error: TypeError : Expecting a Number in argument 2
_x000D_
You could use the Fisher-Yates Shuffle (code adapted from this site):
function shuffle(array) {
let counter = array.length;
// While there are elements in the array
while (counter > 0) {
// Pick a random index
let index = Math.floor(Math.random() * counter);
// Decrease counter by 1
counter--;
// And swap the last element with it
let temp = array[counter];
array[counter] = array[index];
array[index] = temp;
}
return array;
}
One way to do it would be:
//
and before the Code text. Notice the vertical blue line in the below image( that will appear once the selection is made, then you can insert any number of characters in between them)
I couldn't find a direct way to do that. The interesting thing is that it is mentioned in the C# Coding Conventions (C# Programming Guide) under Commenting Conventions.
Insert one space between the comment delimiter (//) and the comment text
But the default implementation of commenting in visual studio doesn't insert any space

In Notepad++, you can use the Mark tab in the Find dialogue to Bookmark all lines matching your query which can be regex or normal (wildcard).
Then use Search > Bookmark > Remove Bookmarked Lines.

I had the same error, but don't know why it appeared. After searching solution I migrated project to AndroidX (Refactor -> Migrate to AndroidX...) and then manually changed whole classes imports etc. and in layout files too (RecyclerViews, ConstraintLayouts, Toolbars etc.). I changed also compileSdkVersion and targetSdkVersion to 28 version and whole project/application works fine.

What I would do is create a Boolean outside your function that starts out as FALSE and gets set to TRUE when you attach the event. This would serve as some sort of flag for you before you attach the event again. Here's an example of the idea.
// initial load
var attached = false;
// this will only execute code once
doSomething = function()
{
if (!attached)
{
attached = true;
//code
}
}
//attach your function with change event
window.onload = function()
{
var txtbox = document.getElementById('textboxID');
if (window.addEventListener)
{
txtbox.addEventListener('change', doSomething, false);
}
else if(window.attachEvent)
{
txtbox.attachEvent('onchange', doSomething);
}
}
I encountered this while using Heroku on Ubuntu, and here's how I fixed it:
Add the PostgreSQL apt repository as described at "Linux downloads (Ubuntu) ". (There are similar pages for other operating systems.)
Upgrade to the latest version (9.3 for me) with:
sudo apt-get install postgresql
Recreate the symbolic link in /usr/bin
with:
sudo ln -s /usr/lib/postgresql/9.3/bin/pg_dump /usr/bin/pg_dump --force
The version number in the /usr/lib/postgresql/...
path above should match the server version
number in the error you received. So if your error says, pg_dump: server version: 9.9
, then link to /usr/lib/postgresql/9.9/...
.
I had a same issue recently with Anaconda with Python 3.7.
I solved this problem by downgrading python version to 3.6:
conda install python=3.6
and then by updating all the packages:
conda update --all
For Ubuntu xampp,
Go to /opt/lampp/etc/extra/
and open httpd-xampp.conf file and add below lines to get remote access,
Order allow,deny
Require all granted
Allow from all
in /opt/lampp/phpmyadmin section.
And restart lampp using, /opt/lampp/lampp restart
I faced this issue too. I was using jquery.poptrox.min.js
for image popping and zooming and I received an error which said:
“Uncaught TypeError: a.indexOf is not a function” error.
This is because indexOf
was not supported in 3.3.1/jquery.min.js
so a simple fix to this is to change it to an old version 2.1.0/jquery.min.js
.
This fixed it for me.

Maybe using Where() before First() can help you, as my problem has been solved in this case.
var documentRow = _dsACL.Documents.Where(o => o.ID == id).FirstOrDefault();
From the respective W3 specifications —which happen to be pretty unclear due to a lack of context— one can deduce the following:
word-break: break-all
is for breaking up foreign, non-CJK (say Western) words in CJK (Chinese, Japanese or Korean) character writings.word-wrap: break-word
is for word breaking in a non-mixed (let us say solely Western) language.At least, these were W3's intentions. What actually happened was a major cock-up with browser incompatibilities as a result. Here is an excellent write-up of the various problems involved.
The following code snippet may serve as a summary of how to achieve word wrapping using CSS in a cross browser environment:
-ms-word-break: break-all;
word-break: break-all;
/* Non standard for webkit */
word-break: break-word;
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;
Leave your email.php code the same, but replace this JavaScript code:
var name = $("#form_name").val();
var email = $("#form_email").val();
var text = $("#msg_text").val();
var dataString = 'name='+ name + '&email=' + email + '&text=' + text;
$.ajax({
type: "POST",
url: "email.php",
data: dataString,
success: function(){
$('.success').fadeIn(1000);
}
});
with this:
$.ajax({
type: "POST",
url: "email.php",
data: $(form).serialize(),
success: function(){
$('.success').fadeIn(1000);
}
});
So that your form input names match up.
You can extract a private key from a keystore with Java6 and OpenSSL. This all depends on the fact that both Java and OpenSSL support PKCS#12-formatted keystores. To do the extraction, you first use keytool
to convert to the standard format. Make sure you use the same password for both files (private key password, not the keystore password) or you will get odd failures later on in the second step.
keytool -importkeystore -srckeystore keystore.jks \
-destkeystore intermediate.p12 -deststoretype PKCS12
Next, use OpenSSL to do the extraction to PEM:
openssl pkcs12 -in intermediate.p12 -out extracted.pem -nodes
You should be able to handle that PEM file easily enough; it's plain text with an encoded unencrypted private key and certificate(s) inside it (in a pretty obvious format).
When you do this, take care to keep the files created secure. They contain secret credentials. Nothing will warn you if you fail to secure them correctly. The easiest method for securing them is to do all of this in a directory which doesn't have any access rights for anyone other than the user. And never put your password on the command line or in environment variables; it's too easy for other users to grab.
SELECT
t.A,
t.B,
t.C,
ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS number
FROM tableZ AS t
See working example at SQLFiddle
Of course, you may want to define the row-numbering order – if so, just swap OVER (ORDER BY (SELECT 1))
for, e.g., OVER (ORDER BY t.C)
, like in a normal ORDER BY
clause.
After two weeks of searching and trying, the following instructions works in
Eclipse Java EE IDE for Web Developers.
Version: Oxygen.3a Release (4.7.3a) Build id: 20180405-1200
as follows:
openFile
--launcher.appendVmargs
-vmargs
-javaagent:/opt/eclipse-spring/lombok.jar
-Dosgi.requiredJavaVersion=1.8
......
In build.gradle dependencies, add lombok.jar from file as follows
compileOnly files('/opt/eclipse-spring/lombok.jar')
And yippee, I have a great day coding with lombok.

Another way would be to use pandas "DateOffset" class
link:-https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.tseries.offsets.DateOffset.html
Using ASGM's code(above in the answers):
from datetime import datetime
import pandas as pd
your_date_string = "April 1, 2012"
format_string = "%B %d, %Y"
datetime_object = datetime.strptime(your_date_string, format_string).date()
new_date = datetime_object + pd.DateOffset(years=1)
new_date.date()
It will return the datetime object with the added year.
Something like this:-
datetime.date(2013, 4, 1)
URL construction is tricky because different parts of the URL have different rules for what characters are allowed: for example, the plus sign is reserved in the query component of a URL because it represents a space, but in the path component of the URL, a plus sign has no special meaning and spaces are encoded as "%20".
RFC 2396 explains (in section 2.4.2) that a complete URL is always in its encoded form: you take the strings for the individual components (scheme, authority, path, etc.), encode each according to its own rules, and then combine them into the complete URL string. Trying to build a complete unencoded URL string and then encode it separately leads to subtle bugs, like spaces in the path being incorrectly changed to plus signs (which an RFC-compliant server will interpret as real plus signs, not encoded spaces).
In Java, the correct way to build a URL is with the URI
class. Use one of the multi-argument constructors that takes the URL components as separate strings, and it'll escape each component correctly according to that component's rules. The toASCIIString()
method gives you a properly-escaped and encoded string that you can send to a server. To decode a URL, construct a URI
object using the single-string constructor and then use the accessor methods (such as getPath()
) to retrieve the decoded components.
Don't use the URLEncoder
class! Despite the name, that class actually does HTML form encoding, not URL encoding. It's not correct to concatenate unencoded strings to make an "unencoded" URL and then pass it through a URLEncoder
. Doing so will result in problems (particularly the aforementioned one regarding spaces and plus signs in the path).
For dynamically center
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
Try this:
par(adj = 0)
plot(1, 1, main = "Title")
or equivalent:
plot(1, 1, main = "Title", adj = 0)
adj = 0
produces left-justified text, 0.5 (the default) centered text and 1 right-justified text. Any value in [0, 1]
is allowed.
However, the issue is that this will also change the position of the label of the x-axis and y-axis.
What I usually do is:
if (cond1 == 'val1' and cond2 == 'val2' and
cond3 == 'val3' and cond4 == 'val4'
):
do_something
this way the closing brace and colon visually mark the end of our condition.
less than o(n) solution will be=>
function(array,k)
var map = {};
for element in array
map(element) = true;
if(map(k-element))
return {k,element}
The problem is what happens when you get NumberFormatexception
thrown? You print it and return nothing.
Note: You don't need to catch and throw an Exception back. Usually it is done to wrap it or print stack trace and ignore for example.
catch(RangeException e) {
throw e;
}
One quick and easy way:
function paintSvgToCanvas(uSvg, uCanvas) {
var pbx = document.createElement('img');
pbx.style.width = uSvg.style.width;
pbx.style.height = uSvg.style.height;
pbx.src = 'data:image/svg+xml;base64,' + window.btoa(uSvg.outerHTML);
uCanvas.getContext('2d').drawImage(pbx, 0, 0);
}
Each time I do a build it auto-increments the least-significant digit.
I don't have any idea how to update the others, but you should at least be seeing that already...
input.name()
needs to be inside a function; classes contain declarations, not random code.
You can use the DateTime.Add() method to add the time to the date.
DateTime date = DateTime.Now;
TimeSpan time = new TimeSpan(36, 0, 0, 0);
DateTime combined = date.Add(time);
Console.WriteLine("{0:dddd}", combined);
You can also create your timespan by parsing a String, if that is what you need to do.
Alternatively, you could look at using other controls. You didn't mention if you are using winforms, wpf or asp.net, but there are various date and time picker controls that support selection of both date and time.
public char lastChar(String s) {
if (s == "" || s == null)
return ' ';
char lc = s.charAt(s.length() - 1);
return lc;
}
for nested arrays you can use:
$data = [
'name[0]' = 'value 1',
'name[1]' = 'value 2',
'name[2]' = 'value 3',
'id' = 'value 4',
....
];
Some JavaScript engines keep keys in insertion order. V8, for instance, keeps all keys in insertion order except for keys that can be parsed as unsigned 32-bit integers.
This means that if you run either of the following:
var animals = {};
animals['dog'] = true;
animals['bear'] = true;
animals['monkey'] = true;
for (var animal in animals) {
if (animals.hasOwnProperty(animal)) {
$('<li>').text(animal).appendTo('#animals');
}
}
var animals = JSON.parse('{ "dog": true, "bear": true, "monkey": true }');
for (var animal in animals) {
$('<li>').text(animal).appendTo('#animals');
}
You'll consistently get dog, bear, and monkey in that order, on Chrome, which uses V8. Node.js also uses V8. This will hold true even if you have thousands of items. YMMV with other JavaScript engines.
Another option is to use the xorshift128plus algorithm:
func xorshift128plus(seed0 : UInt64, _ seed1 : UInt64) -> () -> UInt64 {
var state0 : UInt64 = seed0
var state1 : UInt64 = seed1
if state0 == 0 && state1 == 0 {
state0 = 1 // both state variables cannot be 0
}
func rand() -> UInt64 {
var s1 : UInt64 = state0
let s0 : UInt64 = state1
state0 = s0
s1 ^= s1 << 23
s1 ^= s1 >> 17
s1 ^= s0
s1 ^= s0 >> 26
state1 = s1
return UInt64.addWithOverflow(state0, state1).0
}
return rand
}
This algorithm has a period of 2^128 - 1 and passes all the tests of the BigCrush test suite. Note that while this is a high-quality pseudo-random number generator with a long period, it is not a cryptographically secure random number generator.
You could seed it from the current time or any other random source of entropy. For example, if you had a function called urand64()
that read a UInt64
from /dev/urandom
, you could use it like this:
let rand = xorshift128plus(urand64(), urand64())
for _ in 1...10 {
print(rand())
}
I would like to add to what @Visionscaper says at the top:
Third --> First --> object --> Second --> object
In this case the interpreter doesnt filter out the object class because its duplicated, rather its because Second appears in a head position and doesnt appear in the tail position in a hierarchy subset. While object only appears in tail positions and is not considered a strong position in C3 algorithm to determine priority.
The linearisation(mro) of a class C, L(C), is the
Linearised Merge is done by selecting the common classes that appears as the head of lists and not the tail since order matters(will become clear below)
The linearisation of Third can be computed as follows:
L(O) := [O] // the linearization(mro) of O(object), because O has no parents
L(First) := [First] + merge(L(O), [O])
= [First] + merge([O], [O])
= [First, O]
// Similarly,
L(Second) := [Second, O]
L(Third) := [Third] + merge(L(First), L(Second), [First, Second])
= [Third] + merge([First, O], [Second, O], [First, Second])
// class First is a good candidate for the first merge step, because it only appears as the head of the first and last lists
// class O is not a good candidate for the next merge step, because it also appears in the tails of list 1 and 2,
= [Third, First] + merge([O], [Second, O], [Second])
// class Second is a good candidate for the second merge step, because it appears as the head of the list 2 and 3
= [Third, First, Second] + merge([O], [O])
= [Third, First, Second, O]
Thus for a super() implementation in the following code:
class First(object):
def __init__(self):
super(First, self).__init__()
print "first"
class Second(object):
def __init__(self):
super(Second, self).__init__()
print "second"
class Third(First, Second):
def __init__(self):
super(Third, self).__init__()
print "that's it"
it becomes obvious how this method will be resolved
Third.__init__() ---> First.__init__() ---> Second.__init__() --->
Object.__init__() ---> returns ---> Second.__init__() -
prints "second" - returns ---> First.__init__() -
prints "first" - returns ---> Third.__init__() - prints "that's it"

That's because Bootstrap by default sets the width of the legend
element to 100%. You can fix this by changing your legend.scheduler-border
to also use:
legend.scheduler-border {
width:inherit; /* Or auto */
padding:0 10px; /* To give a bit of padding on the left and right */
border-bottom:none;
}
You'll also need to ensure your custom stylesheet is being added after Bootstrap to prevent Bootstrap overriding your styling - although your styles here should have higher specificity.
You may also want to add margin-bottom:0;
to it as well to reduce the gap between the legend and the divider.

You don't define the vector, url
, before trying to subset it. url
is also a function in the base package, so url[i]
is attempting to subset that function... which doesn't make sense.
You probably defined url
in your prior R session, but forgot to copy that code to your script.

You're thinking too DOM, it's a hard as hell habit to break. Vue recommends you approach it data first.
It's kind of hard to tell in your exact situation but I'd probably use a v-for
and make an array of finds
to push to as I need more.
Here's how I'd set up my instance:
new Vue({
el: '#app',
data: {
finds: []
},
methods: {
addFind: function () {
this.finds.push({ value: '' });
}
}
});
And here's how I'd set up my template:
<div id="app">
<h1>Finds</h1>
<div v-for="(find, index) in finds">
<input v-model="find.value" :key="index">
</div>
<button @click="addFind">
New Find
</button>
</div>
Although, I'd try to use something besides an index
for the key
.
Here's a demo of the above: https://jsfiddle.net/crswll/24txy506/9/
There are two solutions posted on that page. The one with lower votes I would recommend if possible.
If you are using HTML5 then it is perfectly valid to put a div
inside of a
. As long as the div doesn't also contain some other specific elements like other link tags.
<a href="Music.html">
<div id="music" class="nav">
Music I Like
</div>
</a>
The solution you are confused about actually makes the link as big as its container div. To make it work in your example you just need to add position: relative
to your div. You also have a small syntax error which is that you have given the span a class instead of an id. You also need to put your span inside the link because that is what the user is clicking on. I don't think you need the z-index
at all from that example.
div { position: relative; }
.hyperspan {
position:absolute;
width:100%;
height:100%;
left:0;
top:0;
}
<div id="music" class="nav">Music I Like
<a href="http://www.google.com">
<span class="hyperspan"></span>
</a>
</div>
When you give absolute
positioning to an element it bases its location and size after the first parent it finds that is relatively positioned. If none, then it uses the document. By adding relative
to the parent div you tell the span to only be as big as that.
I know this is a little old but I wanted to add an updated answer with f-strings which were introduced in Python version 3.6:

Assuming you question is about REST webservices design and more precisely concerning success/error.
I think there are 3 different types of design.
Use only HTTP Status code to indicate if there was an error and try to limit yourself to the standard ones (usually it should suffice).
Use HTTP Status + json body (even if it is an error). Define a uniform structure for errors (ex: code, message, reason, type, etc) and use it for errors, if it is a success then just return the expected json response.
Forget the http status (ex: always status 200), always use json and add at the root of the response a boolean responseValid and a error object (code,message,etc) that will be populated if it is an error otherwise the other fields (success) are populated.
Pros: The client deals only with the body of the response that is a json string and ignores the status(?).
Cons: The less standard.
It's up to you to choose :)
Depending on the API I would choose 2 or 3 (I prefer 2 for json rest apis). Another thing I have experienced in designing REST Api is the importance of documentation for each resource (url): the parameters, the body, the response, the headers etc + examples.
I would also recommend you to use jersey (jax-rs implementation) + genson (java/json databinding library). You only have to drop genson + jersey in your classpath and json is automatically supported.
EDIT:
Solution 2 is the hardest to implement but the advantage is that you can nicely handle exceptions and not only business errors, initial effort is more important but you win on the long term.
Solution 3 is the easy to implement on both, server side and client but it's not so nice as you will have to encapsulate the objects you want to return in a response object containing also the responseValid + error.

Good news, so the OP's original use case of mapping pairs retrieved from a database with unique string ids as keys and numeric values as values into a built-in Python v3.6+ dict, should now respect the insert order.
If say the resulting two column table expressions from a database query like:
SELECT a_key, a_value FROM a_table ORDER BY a_value;
would be stored in two Python tuples, k_seq and v_seq (aligned by numerical index and with the same length of course), then:
k_seq = ('foo', 'bar', 'baz')
v_seq = (0, 1, 42)
ordered_map = dict(zip(k_seq, v_seq))
Allow to output later as:
for k, v in ordered_map.items():
print(k, v)
yielding in this case (for the new Python 3.6+ built-in dict!):
foo 0
bar 1
baz 42
in the same ordering per value of v.
Where in the Python 3.5 install on my machine it currently yields:
bar 1
foo 0
baz 42
As proposed in 2012 by Raymond Hettinger (cf. mail on python-dev with subject "More compact dictionaries with faster iteration") and now (in 2016) announced in a mail by Victor Stinner to python-dev with subject "Python 3.6 dict becomes compact and gets a private version; and keywords become ordered" due to the fix/implementation of issue 27350 "Compact and ordered dict" in Python 3.6 we will now be able, to use a built-in dict to maintain insert order!!
Hopefully this will lead to a thin layer OrderedDict implementation as a first step. As @JimFasarakis-Hilliard indicated, some see use cases for the OrderedDict type also in the future. I think the Python community at large will carefully inspect, if this will stand the test of time, and what the next steps will be.
Time to rethink our coding habits to not miss the possibilities opened by stable ordering of:
The first because it eases dispatch in the implementation of functions and methods in some cases.
The second as it encourages to more easily use dict
s as intermediate storage in processing pipelines.
Raymond Hettinger kindly provided documentation explaining "The Tech Behind Python 3.6 Dictionaries" - from his San Francisco Python Meetup Group presentation 2016-DEC-08.
And maybe quite some Stack Overflow high decorated question and answer pages will receive variants of this information and many high quality answers will require a per version update too.
As @ajcr rightfully notes: "The order-preserving aspect of this new implementation is considered an implementation detail and should not be relied upon." (from the whatsnew36) not nit picking, but the citation was cut a bit pessimistic ;-). It continues as " (this may change in the future, but it is desired to have this new dict implementation in the language for a few releases before changing the language spec to mandate order-preserving semantics for all current and future Python implementations; this also helps preserve backwards-compatibility with older versions of the language where random iteration order is still in effect, e.g. Python 3.5)."
So as in some human languages (e.g. German), usage shapes the language, and the will now has been declared ... in whatsnew36.
In a mail to the python-dev list, Guido van Rossum declared:
Make it so. "Dict keeps insertion order" is the ruling. Thanks!
So, the version 3.6 CPython side-effect of dict insertion ordering is now becoming part of the language spec (and not anymore only an implementation detail). That mail thread also surfaced some distinguishing design goals for collections.OrderedDict
as reminded by Raymond Hettinger during discussion.

If you use a "text variable" tk.StringVar()
, you can just set()
that.
No need to use the Entry delete and insert. Moreover, those functions don't work when the Entry is disabled or readonly! The text variable method, however, does work under those conditions as well.
import Tkinter as tk
...
entryText = tk.StringVar()
entry = tk.Entry( master, textvariable=entryText )
entryText.set( "Hello World" )
Erm, why would you want to? Leave PHP on the backend and NodeJS/Sockets to do its non-blocking thing.
Here is something to get you started: http://groups.google.com/group/socket_io/browse_thread/thread/74a76896d2b72ccc
Personally I have express running with an endpoint that is listening expressly for interaction from PHP.
For example, if I have sent a user an email, I want socket.io to display a real-time notification to the user.
Want interaction from socket.io to php, well you can just do something like this:
var http = require('http'),
host = WWW_HOST,
clen = 'userid=' + userid,
site = http.createClient(80, host),
request = site.request("POST", "/modules/nodeim/includes/signonuser.inc.php",
{'host':host,'Content-Length':clen.length,'Content-Type':'application/x-www-form-urlencoded'});
request.write('userid=' + userid);
request.end();
Seriously, PHP is great for doing server side stuff and let it be with the connections it has no place in this domain now. Why do anything long-polling when you have websockets or flashsockets.
for( int i = 1; i * i <= num; i++ )
{
/* upto sqrt is because every divisor after sqrt
is also found when the number is divided by i.
EXAMPLE like if number is 90 when it is divided by 5
then you can also see that 90/5 = 18
where 18 also divides the number.
But when number is a perfect square
then num / i == i therefore only i is the factor
*/
You can use a light weight webserver to serve the file.
For example,
1. install Node
2. install the "http-server" (or similar) package
3. Run the http-server package ( "http-server -c-1") from the folder where the script file is located
4. Load the script from chrome console (run the following script on chrome console
var ele = document.createElement("script");
var scriptPath = "http://localhost:8080/{scriptfilename}.js" //verify the script path
ele.setAttribute("src",scriptPath);
document.head.appendChild(ele)
I use __dict__
Example:
class MyObj(object):
def __init__(self):
self.name = 'Chuck Norris'
self.phone = '+6661'
obj = MyObj()
print(obj.__dict__)
# Output:
# {'phone': '+6661', 'name': 'Chuck Norris'}
You need to specify the minimum width of the field.
String.format("%" + numberOfSpaces + "s", "");
Why do you want to generate a String of spaces of a certain length.
If you want a column of this length with values then you can do:
String.format("%" + numberOfSpaces + "s", "Hello");
which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

GRANT pg_read_server_files TO my_user WITH ADMIN OPTION;
var iframe = document.getElementById('iframeId');
var innerDoc = (iframe.contentDocument) ? iframe.contentDocument : iframe.contentWindow.document;
You could more simply write:
var iframe = document.getElementById('iframeId');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
and the first valid inner doc will be returned.
Once you get the inner doc, you can just access its internals the same way as you would access any element on your current page. (innerDoc.getElementById
...etc.)
IMPORTANT: Make sure that the iframe is on the same domain, otherwise you can't get access to its internals. That would be cross-site scripting.
If you are looking for a way to do this without inheritance:
extension UILabel {
func underline() {
if let textString = self.text {
let attributedString = NSMutableAttributedString(string: textString)
attributedString.addAttribute(NSAttributedString.Key.underlineStyle,
value: NSUnderlineStyle.single.rawValue,
range: NSRange(location: 0, length: attributedString.length))
attributedText = attributedString
}
}
}
// in swift 4 - switch NSUnderlineStyleAttributeName with NSAttributedStringKey.underlineStyle
extension UILabel {
func underline() {
if let textString = self.text {
let attributedString = NSMutableAttributedString(string: textString)
attributedString.addAttribute(NSUnderlineStyleAttributeName, value: NSUnderlineStyle.styleSingle.rawValue, range: NSRange(location: 0, length: attributedString.length))
attributedText = attributedString
}
}
}
extension UIButton {
func underline() {
let attributedString = NSMutableAttributedString(string: (self.titleLabel?.text!)!)
attributedString.addAttribute(NSUnderlineStyleAttributeName, value: NSUnderlineStyle.styleSingle.rawValue, range: NSRange(location: 0, length: (self.titleLabel?.text!.characters.count)!))
self.setAttributedTitle(attributedString, for: .normal)
}
}
Is not recommended but.... you can use componentWillMount from your app class to add your global variables trough it... a bit like so:
componentWillMount: function () {
window.MyVars = {
ajax: require('../helpers/ajax.jsx'),
utils: require('../helpers/utils.jsx')
};
}
still consider this a hack... but it will get your job done
btw componentWillMount executes once before rendering, see more here: https://reactjs.org/docs/react-component.html#mounting-componentwillmount
To check a remote SSH server prior to the first connection, you can give a look at www.server-stats.net/ssh/ to see all SHH keys for the server, as well as from when the key is known.
That's not like an SSL certificate, but definitely a must-do before connecting to any SSH server for the first time.
Subsetting the data and combining them back is unnecessary. So are loops since those operations are vectorized. From your previous edit, I'm guessing you are doing all of this to make bubble plots. If that is correct, perhaps the example below will help you. If this is way off, I can just delete the answer.
library(ggplot2)
# let's look at the included dataset named trees.
# ?trees for a description
data(trees)
ggplot(trees,aes(Height,Volume)) + geom_point(aes(size=Girth))
# Great, now how do we color the bubbles by groups?
# For this example, I'll divide Volume into three groups: lo, med, high
trees$set[trees$Volume<=22.7]="lo"
trees$set[trees$Volume>22.7 & trees$Volume<=45.4]="med"
trees$set[trees$Volume>45.4]="high"
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth))
# Instead of just circles scaled by Girth, let's also change the symbol
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=set))
# Now let's choose a specific symbol for each set. Full list of symbols at ?pch
trees$symbol[trees$Volume<=22.7]=1
trees$symbol[trees$Volume>22.7 & trees$Volume<=45.4]=2
trees$symbol[trees$Volume>45.4]=3
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=symbol))
The key here is to unlist the row first.
colnames(DF) <- as.character(unlist(DF[1,]))
DF = DF[-1, ]
Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:
type: "GET",
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
},
success: function (data) {
alert(data);
});
The const
qualifier means that the methods can be called on any value of foobar
. The difference comes when you consider calling a non-const method on a const object. Consider if your foobar
type had the following extra method declaration:
class foobar {
...
const char* bar();
}
The method bar()
is non-const and can only be accessed from non-const values.
void func1(const foobar& fb1, foobar& fb2) {
const char* v1 = fb1.bar(); // won't compile
const char* v2 = fb2.bar(); // works
}
The idea behind const
though is to mark methods which will not alter the internal state of the class. This is a powerful concept but is not actually enforceable in C++. It's more of a promise than a guarantee. And one that is often broken and easily broken.
foobar& fbNonConst = const_cast<foobar&>(fb1);
A little bit modified answer of @cope360:
create table test (a int, b int, c int, constraint pk_test primary key(c, a, b));
select i.relname as index_name,
ix.indisunique as is_unique,
a.attname as column_name,
from pg_class c
inner join pg_index ix on c.oid=ix.indrelid
inner join pg_class i on ix.indexrelid=i.oid
inner join pg_attribute a on a.attrelid=c.oid and a.attnum=any(ix.indkey)
where c.oid='public.test'::regclass::oid
order by array_position(ix.indkey, a.attnum) asc;
This will show the index columns in correct order:
index_name is_unique column_name
pk_test true c
pk_test true a
pk_test true b
Use ElasticDump

I have posted my answer to another post with the same question with this one.
From Apple iOS7 transition Guide, https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/TransitionGuide/AppearanceCustomization.html#//apple_ref/doc/uid/TP40013174-CH15-SW1
Specifically automaticallyAdjustsScrollViewInsets=YES
and set self.edgesForExtendedLayout = UIRectEdgeNone
works for me when I don't want to the overlap and I have a tableviewcontroller
.
If you are using Spring as Back-End server and especially using Spring Security then i found a solution by putting http.cors();
in the configure
method. The method looks like that:
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests() // authorize
.anyRequest().authenticated() // all requests are authenticated
.and()
.httpBasic();
http.cors();
}
You can easily increase your VM's RAM by modifying the memory property of config.vm.provider section in your vagrant file.
config.vm.provider "virtualbox" do |vb|
vb.memory = "4096"
end
This allocates about 4GB of RAM to your VM. You can change this according to your requirement. For example, following setting would allocate 2GB of RAM to your VM.
config.vm.provider "virtualbox" do |vb|
vb.memory = "2048"
end
Try removing the config.vm.customize ["modifyvm", :id, "--memory", 1024]
in your file, and adding the above code.
For the network configuration, try modifying the config.vm.network :hostonly, "199.188.44.20"
in your file toconfig.vm.network "private_network", ip: "199.188.44.20"
var date = new Date('2012.08.10');
var unixTimeStamp = Math.floor(date.getTime() / 1000);
In this case it's important to return only a whole number (so a simple division won't do), and also to only return actually elapsed seconds (that's why this code uses Math.floor()
and not Math.round()
).
Just check the bootstrap. CSS and search for the class panel-heading and copy the default code.
Copy the default CSS to your personal CSS but vive it a diference classname like my-panel-header for example.
Edit the css Code from the new clones class created.
Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.
git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67
Then, abort the rebase again.
If you use maven, add the following to your pom.xml file:
<plugin>
<!-- Build an executable JAR -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<mainClass>com.path.to.YourMainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
Then you can run mvn package
. The jar file will be located under in the target directory.
After trying a few of these answers and finding they don't scale well with multiple links (for example the accepted answer requires a line of jquery for every link you have), I came across a way that requires minimal code to get working, and it also appears to work perfectly, at least on Chrome.
You add this line to activate it:
$('[data-toggle="popover"]').popover();
And these settings to your anchor links:
data-toggle="popover" data-trigger="hover"
See it in action here, I'm using the same imports as the accepted answer so it should work fine on older projects.
You can get rid of the first line. You don't need import java.lang.*;
Just change your 5th line to:
public static void main(String [] args) throws Exception
earl's answer gives you the solution, but I thought I'd add what the problem is that's causing your IllegalStateException
. You're calling group(1)
without having first called a matching operation (such as find()
). This isn't needed if you're just using $1
since the replaceAll()
is the matching operation.
It's hard to say without knowing the whole context of the problem, but I would not override __iter__
.
I would implement __what_goes_here__
on the class.
as_dict(self:
d = {...whatever you need...}
return d
File SongsTableSeeder.php should be in database/seeds directory or in its subdirectory.
You need to run:
composer dump-autoload
and then:
php artisan db:seed
or:
php artisan db:seed --class=SongsTableSeeder
Just after your Page_Load add this:
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
Note that I don't do anything in the function.
EDIT: Tim answered the same thing. :) You can also find the answer Here
Use this command, (go to java < jdk < bin path in cmd prompt)
$ jarsigner -verify -verbose -certs my_application.apk
If you see "CN=Android Debug", this means the .apk was signed with the debug key generated by the Android SDK (means it is unsigned), otherwise you will find something for CN. For more details see: http://developer.android.com/guide/publishing/app-signing.html
Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.
The relevant paragraph:
Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.
This makes lots of sense.
For your specific question.. the o
in the <o:p>
means "Office namespace" so anything following the o:
in a tag means "I'm part of Office namespace" - in case of <o:p>
it just means paragraph, the equivalent of the ordinary <p>
tag.
I assume that every HTML tag has its Office "equivalent" and they have more.

I love FLOSS Weekly. Another Twit Podcast where Leo and Randal Schwartz interview open source geeks. My favorite was their interview with Dan Ingalls (Smalltalk/Squeak fame). I also enjoyed their interview of Richard Hipp (SQLite).
They are very similar. Some may argue that @import is more maintainable. However, each @import will cost you a new HTTP request in the same fashion as using the "link" method. So in the context of speed it is no faster. And as "duskwuff" said, it doesn't load simultaneously which is a downfall.
You need to initialize it first:
p = Pump().getPumps()
I've used the following script with great success on numerous servers:
pid=`jps -v | grep $INSTALLATION | awk '{print $1}'`
echo $INSTALLATION found at PID $pid
while [ -e /proc/$pid ]; do sleep 0.1; done
notes:
$INSTALLATION
contains enough of the process path that's it's totally unambiguousThis script is actually used to shut down a running instance of tomcat, which I want to shut down (and wait for) at the command line, so launching it as a child process simply isn't an option for me.
I have a case scenario and I tried all the answers from above, but always new image was created on top of the old one. The solution that worked for me is:
imageView.setImageResource(R.drawable.image);
Intent intent = new Intent(YourCurrentActivity.this, YourActivityName.class);
intent.putExtra("NAme","John");
intent.putExtra("Id",1);
startActivity(intent);
You can retrieve it in another activity. Two ways:
int id = getIntent.getIntExtra("id", /* defaltvalue */ 2);
The second way is:
Intent i = getIntent();
String name = i.getStringExtra("name");
Below works for first tr
of the table under thead
table thead tr:first-child {
background: #f2f2f2;
}
And this works for the first tr
of thead
and tbody
both:
table thead tbody tr:first-child {
background: #f2f2f2;
}
I use this it works for me
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), 1);
On submitting, you would get an array as if created like this:
$_POST['topdiameter'] = array( 'first value', 'second value' );
$_POST['bottomdiameter'] = array( 'first value', 'second value' );
However, I would suggest changing your form names to this format instead:
name="diameters[0][top]"
name="diameters[0][bottom]"
name="diameters[1][top]"
name="diameters[1][bottom]"
...
Using that format, it's much easier to loop through the values.
if ( isset( $_POST['diameters'] ) )
{
echo '<table>';
foreach ( $_POST['diameters'] as $diam )
{
// here you have access to $diam['top'] and $diam['bottom']
echo '<tr>';
echo ' <td>', $diam['top'], '</td>';
echo ' <td>', $diam['bottom'], '</td>';
echo '</tr>';
}
echo '</table>';
}
I don't know exactly what you want to use this for, so I'm not sure if this would work for you, but I just did the following and it worked for my use case:
const newObj ={...obj, [key]: undefined}
delete this line:
jsonp: 'jsonp_callback',
Or replace this line:
url: 'http://url.of.my.server/submit?callback=json_callback',
because currently you are asking jQuery to create a random callback function name with callback=?
and then telling jQuery that you want to use jsonp_callback
instead.
You would need to create a generic class named MyProp. Then, you will need to add implicit or explicit cast operators so you can get and set the value as if it were the type specified in the generic type parameter. These cast operators can do the extra work that you need.
Use:
struct arg_struct *args = malloc(sizeof(struct arg_struct));
And pass this arguments like this:
pthread_create(&tr, NULL, print_the_arguments, (void *)args);
Don't forget free args! ;)
If you are using the requests lib:
import requests
...
params = {'tag': 'python'}
requests.get(url, params=params)
I had the same problem, and xmltable helped me:
SELECT id, trim(COLUMN_VALUE) text FROM t, xmltable(('"' || REPLACE(text, ',', '","') || '"'))
To summarize a few items here: There are some pixel-by-pixel options that, while being simple just aren't fast.
@Luis' comment linking to: (archived) https://web.archive.org/web/20110827032809/http://www.switchonthecode.com/tutorials/csharp-tutorial-convert-a-color-image-to-grayscale is superb.
He runs through three different options and includes timings for each.
An alternative approach is to use numpy.resize()
as in:
In [37]: shp = (50,100,25)
In [38]: arr = np.random.random_sample(shp)
In [45]: resized_arr = np.resize(arr, (np.prod(shp[:2]), shp[-1]))
In [46]: resized_arr.shape
Out[46]: (5000, 25)
# sanity check with other solutions
In [47]: resized = np.reshape(arr, (-1, shp[-1]))
In [48]: np.allclose(resized_arr, resized)
Out[48]: True
You have to install grunt in your project folder
create your package.json
$ npm init
install grunt for this project, this will be installed under node_modules/
. --save-dev will add this module to devDependency in your package.json
$ npm install grunt --save-dev
then create gruntfile.js and run
$ grunt
You can use ng-include
directive.
Try something like this:
emanuel.directive('hymn', function() {
return {
restrict: 'E',
link: function(scope, element, attrs) {
scope.getContentUrl = function() {
return 'content/excerpts/hymn-' + attrs.ver + '.html';
}
},
template: '<div ng-include="getContentUrl()"></div>'
}
});
UPD. for watching ver
attribute
emanuel.directive('hymn', function() {
return {
restrict: 'E',
link: function(scope, element, attrs) {
scope.contentUrl = 'content/excerpts/hymn-' + attrs.ver + '.html';
attrs.$observe("ver",function(v){
scope.contentUrl = 'content/excerpts/hymn-' + v + '.html';
});
},
template: '<div ng-include="contentUrl"></div>'
}
});
If the jre is installed on your machine properly then look for keytool in jre or in jre/bin
to find where jre is installed, use this
sudo find / -name jre
Then look for keytool in path_to_jre or in path_to_jre/bin
cd to keytool location
then run ./keytool
Make sure to add the the path to $PATH by
export PATH=$PATH:location_to_keytool
To make sure you got it right after this, run
where keytool
for future edit you bash or zshrc file and source it
So to make your expression work, changing &&
for -a
will do the trick.
It is correct like this:
if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
then ....
or like
if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
then ....
or even
if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
then ....
You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.
You have to go to Control Panel>Programs>Turn Windows features on or off. Then, check "Telnet Client" and save the changes. You might have to wait about a few minutes before the change could take effect.
Yes. Internally it is implemented as open hashing based on a primitive polynomial over Z/2 (source).
Use DateTime.Today as opposed to DateTime.Now (which is what Get-Date returns) because Today is just the date with 00:00 as the time, and now is the moment in time down to the millisecond. (from masenkablast)

My guess is that the webpage is listening to mousedown rather than click (which is bad for accessibility because when a user uses the keyboard, only focus and click are fired, not mousedown). So you should simulate mousedown, click, and mouseup (which, by the way, is what the iPhone, iPod Touch, and iPad do on tap events).
To simulate the mouse events, you can use this snippet for browsers that support DOM 2 Events. For a more foolproof simulation, fill in the mouse position using initMouseEvent
instead.
// DOM 2 Events
var dispatchMouseEvent = function(target, var_args) {
var e = document.createEvent("MouseEvents");
// If you need clientX, clientY, etc., you can call
// initMouseEvent instead of initEvent
e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
dispatchMouseEvent(element, 'mouseover', true, true);
dispatchMouseEvent(element, 'mousedown', true, true);
dispatchMouseEvent(element, 'click', true, true);
dispatchMouseEvent(element, 'mouseup', true, true);
When you fire a simulated click event, the browser will actually fire the default action (e.g. navigate to the link's href, or submit a form).
In IE, the equivalent snippet is this (unverified since I don't have IE). I don't think you can give the event handler mouse positions.
// IE 5.5+
element.fireEvent("onmouseover");
element.fireEvent("onmousedown");
element.fireEvent("onclick"); // or element.click()
element.fireEvent("onmouseup");
You can simulate keydown and keypress events, but unfortunately in Chrome they only fire the event handlers and don't perform any of the default actions. I think this is because the DOM 3 Events working draft describes this funky order of key events:
This means that you have to (while combing the HTML5 and DOM 3 Events drafts) simulate a large amount of what the browser would otherwise do. I hate it when I have to do that. For example, this is roughly how to simulate a key press on an input or textarea.
// DOM 3 Events
var dispatchKeyboardEvent = function(target, initKeyboradEvent_args) {
var e = document.createEvent("KeyboardEvents");
e.initKeyboardEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
var dispatchTextEvent = function(target, initTextEvent_args) {
var e = document.createEvent("TextEvent");
e.initTextEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
var dispatchSimpleEvent = function(target, type, canBubble, cancelable) {
var e = document.createEvent("Event");
e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
var canceled = !dispatchKeyboardEvent(element,
'keydown', true, true, // type, bubbles, cancelable
null, // window
'h', // key
0, // location: 0=standard, 1=left, 2=right, 3=numpad, 4=mobile, 5=joystick
''); // space-sparated Shift, Control, Alt, etc.
dispatchKeyboardEvent(
element, 'keypress', true, true, null, 'h', 0, '');
if (!canceled) {
if (dispatchTextEvent(element, 'textInput', true, true, null, 'h', 0)) {
element.value += 'h';
dispatchSimpleEvent(element, 'input', false, false);
// not supported in Chrome yet
// if (element.form) element.form.dispatchFormInput();
dispatchSimpleEvent(element, 'change', false, false);
// not supported in Chrome yet
// if (element.form) element.form.dispatchFormChange();
}
}
dispatchKeyboardEvent(
element, 'keyup', true, true, null, 'h', 0, '');
I don't think it is possible to simulate key events in IE.
Just press Ctrl + Shift + R and see...
In SQL Server Management Studio, Ctrl+Shift+R refreshes the local cache.
To get the maximum value of a column across a set of rows:
SELECT MAX(column1) FROM table; -- expect one result
To get the maximum value of a set of columns, literals, or variables for each row:
SELECT GREATEST(column1, 1, 0, @val) FROM table; -- expect many results
Unless you are writing very small files, you should probably use templates.
Example:
- name: copy upstart script
template:
src: myCompany-service.conf.j2
dest: "/etc/init/myCompany-service.conf"
According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.
Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.
Use the HorizontalAlignment and VerticalAlignment layout properties. They control how an element uses the space it has inside its parent when more room is available than it required by the element.
The width of a StackPanel, for example, will be as wide as the widest element it contains. So, all narrower elements have a bit of excess space. The alignment properties control what the child element does with the extra space.
The default value for both properties is Stretch, so the child element is stretched to fill all available space. Additional options include Left, Center and Right for HorizontalAlignment and Top, Center and Bottom for VerticalAlignment.
If you're dealing with a Java character array (such as password characters that you read from the console), you can convert it to a JRuby string with the following Ruby code:
# GIST: "pw_from_console.rb" under "https://gist.github.com/drhuffman12"
jconsole = Java::java.lang.System.console()
password = jconsole.readPassword()
ruby_string = ''
password.to_a.each {|c| ruby_string << c.chr}
# .. do something with 'password' variable ..

Use the function String.Contains();
an example call,
abs.Contains("s"); // to look for lower case s
here is more from MSDN.
I found this solution which solved the problem for me: Removing all entries in your *.csproj
that fall into:
<manifestcertificatethumbprint>...</manifestcertificatethumbprint>
<manifestkeyfile>...</manifestkeyfile>
<generatemanifests>...</generatemanifests>
<signmanifests>...</signmanifests>
In my case I had a panda Series where the values are tuples of characters:
Out[67]
0 (H, H, H, H)
1 (H, H, H, T)
2 (H, H, T, H)
3 (H, H, T, T)
4 (H, T, H, H)
Therefore I could use indexing to filter the series, but to create the index I needed apply
. My condition is "find all tuples which have exactly one 'H'".
series_of_tuples[series_of_tuples.apply(lambda x: x.count('H')==1)]
I admit it is not "chainable", (i.e. notice I repeat series_of_tuples
twice; you must store any temporary series into a variable so you can call apply(...) on it).
There may also be other methods (besides .apply(...)
) which can operate elementwise to produce a Boolean index.
Many other answers (including accepted answer) using the chainable functions like:
.compress()
.where()
.loc[]
[]
These accept callables (lambdas) which are applied to the Series, not to the individual values in those series!
Therefore my Series of tuples behaved strangely when I tried to use my above condition / callable / lambda, with any of the chainable functions, like .loc[]
:
series_of_tuples.loc[lambda x: x.count('H')==1]
Produces the error:
KeyError: 'Level H must be same as name (None)'
I was very confused, but it seems to be using the Series.count series_of_tuples.count(...)
function , which is not what I wanted.
I admit that an alternative data structure may be better:
This creates a series of strings (i.e. by concatenating the tuple; joining the characters in the tuple on a single string)
series_of_tuples.apply(''.join)
So I can then use the chainable Series.str.count
series_of_tuples.apply(''.join).str.count('H')==1

I had the same problem. I googled it for two days. At last I accidentally noticed that the problem was access modifier of the constructor of the Controller.
I didn’t put the public
key word behind the Controller’s constructor.
public class MyController : ApiController
{
private readonly IMyClass _myClass;
public MyController(IMyClass myClass)
{
_myClass = myClass;
}
}
I add this experience as another answer maybe someone else made a similar mistake.
Add your C:\WinPython-64bit-3.4.4.1\python_***\Scripts folder to your system PATH variable by doing the following:
Click Environment Variables. ...
In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. ...
SOAP - "Simple Object Access Protocol"
SOAP is a method of transferring messages, or small amounts of information, over the Internet. SOAP messages are formatted in XML and are typically sent using HTTP (hypertext transfer protocol).
Rest - Representational state transfer
Rest is a simple way of sending and receiving data between client and server and it doesn't have very many standards defined. You can send and receive data as JSON, XML or even plain text. It's light weighted compared to SOAP.
Place the body of your loop after the while
and before the test. The actual body of the while
loop should be a no-op.
while
check_if_file_present
#do other stuff
(( current_time <= cutoff ))
do
:
done
Instead of the colon, you can use continue
if you find that more readable. You can also insert a command that will only run between iterations (not before first or after last), such as echo "Retrying in five seconds"; sleep 5
. Or print delimiters between values:
i=1; while printf '%d' "$((i++))"; (( i <= 4)); do printf ','; done; printf '\n'
I changed the test to use double parentheses since you appear to be comparing integers. Inside double square brackets, comparison operators such as <=
are lexical and will give the wrong result when comparing 2 and 10, for example. Those operators don't work inside single square brackets.

UPDATE: Since I wrote this, the input event has gotten a decent level of support. It is still not 100% in IE9, so you will have to wait a bit until IE9 is fully phased out. In light of my answer to this question, however, input is more than a decent replacement for the method I've presented, so I recommend switching.
Use keyup
event
var inp = document.getElementById('myinput');_x000D_
var chars = document.getElementById('chars');_x000D_
inp.onkeyup = function() {_x000D_
chars.innerHTML = inp.value.length;_x000D_
}
_x000D_
<input id="myinput"><span id="chars">0</span>
_x000D_
Just a note for those that suggest keydown. That won't work. The keydown fires before character is added to the input box or textarea, so the length of the value would be wrong (one step behind). Therefore, the only solution that works is keyup, which fires after the character is added.
You might be able to achieve your goal by using it in a function, and then examining the function's source with toString()
:
var whatsMyName;
// Just do something with the whatsMyName variable, no matter what
function func() {var v = whatsMyName;}
// Now that we're using whatsMyName in a function, we could get the source code of the function as a string:
var source = func.toString();
// Then extract the variable name from the function source:
var result = /var v = (.[^;]*)/.exec(source);
alert(result[1]); // Should alert 'whatsMyName';
Here is some one liner xpath 1.0 expressions for IndexOf( $text, $searchString ):
If you need the position of the FIRST character of the sought string, or 0 if it is not present:
contains($text,$searchString)*(1 + string-length(substring-before($text,$searchString)))
If you need the position of the first character AFTER the found string, or 0 if it is not present:
contains($text,$searchString)*(1 + string-length(substring-before($text,$searchString)) + string-length($searchString))
Alternatively if you need the position of the first character AFTER the found string, or length+1 if it is not present:
1 + string-length($right) - string-length(substring-after($right,$searchString))
That should cover most cases that you need.
Note: The multiplication by contains( ... ) causes the true or false result of the contains( ... ) function to be converted to 1 or 0, which elegantly provides the "0 when not found" part of the logic.
