Before you install Jenkins you should install JDK:
apt install openjdk-8-jre
After this install Jenkins:
apt-get install jenkins
And check Jenkins status (should be 'active'):
systemctl status jenkins.service
Remember that the insertion order isn't respected in a map generally speaking. Try this :
/**
* Get the first element of a map. A map doesn't guarantee the insertion order
* @param map
* @param <E>
* @param <K>
* @return
*/
public static <E,K> K getFirstKeyValue(Map<E,K> map){
K value = null;
if(map != null && map.size() > 0){
Map.Entry<E,K> entry = map.entrySet().iterator().next();
if(entry != null)
value = entry.getValue();
}
return value;
}
I use this only when I am sure that that map.size() == 1
.
Depends exactly what you mean by create but some other ones are:
This should work:
start "" "c:\program files\php\php.exe" D:\mydocs\mp\index.php param1 param2
The start
command interprets the first argument as a window title if it contains spaces. In this case, that means start
considers your whole argument a title and sees no command. Passing ""
(an empty title) as the first argument to start
fixes the problem.

What I did is first check what are the running processes by
SELECT * FROM pg_stat_activity WHERE state = 'active';
Find the process you want to kill, then type:
SELECT pg_cancel_backend(<pid of the process>)
This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.
If the process cannot be killed, try:
SELECT pg_terminate_backend(<pid of the process>)
The function combn is in the standard utils package (i.e. already installed)
choose is also already available in the Special {base}
You can use TimerTask for Cronjobs.
Main.java
public class Main{
public static void main(String[] args){
Timer t = new Timer();
MyTask mTask = new MyTask();
// This task is scheduled to run every 10 seconds
t.scheduleAtFixedRate(mTask, 0, 10000);
}
}
MyTask.java
class MyTask extends TimerTask{
public MyTask(){
//Some stuffs
}
@Override
public void run() {
System.out.println("Hi see you after 10 seconds");
}
}
Alternative You can also use ScheduledExecutorService.
The easiest way it to use a regular expression:
Regular Expression for alphanumeric and underscores
Using regular expressions in .net:
http://www.regular-expressions.info/dotnet.html
var regexItem = new Regex("^[a-zA-Z0-9 ]*$");
if(regexItem.IsMatch(YOUR_STRING)){..}
Well there's the Network Connections preference page; you can add proxies there. I don't know much about it; I don't know if the Maven integration plugins will use the proxies defined there.
You can find it at Window...Preferences, then General...Network Connections.
They are lists because you type them as lists in the dictionary:
bikes = {
# Bike designed for children"
"Trike": ["Trike", 20, 100],
# Bike designed for everyone"
"Kruzer": ["Kruzer", 50, 165]
}
You should use the bike-class instead:
bikes = {
# Bike designed for children"
"Trike": Bike("Trike", 20, 100),
# Bike designed for everyone"
"Kruzer": Bike("Kruzer", 50, 165)
}
This will allow you to get the cost of the bikes with bike.cost as you were trying to.
for bike in bikes.values():
profit = bike.cost * margin
print(bike.name + " : " + str(profit))
This will now print:
Kruzer : 33.0
Trike : 20.0
Prevent saving changes that require table re-creation

- OK.
After saving, repeat the proceudure to re-tick the box. This safe-guards against accidental data loss.
Further explanation
By default SQL Server Management Studio prevents the dropping of tables, because when a table is dropped its data contents are lost.*
When altering a column's datatype in the table Design view, when saving the changes the database drops the table internally and then re-creates a new one.
*Your specific circumstances will not pose a consequence since your table is empty. I provide this explanation entirely to improve your understanding of the procedure.

ISO 8601 format (2018-12-23T12:34:56
) is more readable than UNIX timestamp. However on some OSs you cannot have :
in the filenames. Therefore I recommend using something like this instead:
2018-12-23_12-34-56
You can use the following command to get the timestamp in this format:
TIMESTAMP=`date +%Y-%m-%d_%H-%M-%S`
This is the format I have seen many applications use. Another nice thing about this is that if your file names start with this, you can sort them alphabetically and they would be sorted by date.
For a Windows solution I've found that disabling and re-enabling the Arduino in Device Manager, then restarting the Arduino IDE does the trick without fail (no unplugging necessary). Why this error occurs in the first place is beyond me. Perhaps the corresponding method for Linux will fix your problem.
Slightly related (not really), I had an issue with an AVR board a while back which was fixed by setting the device to a new COM port in the driver settings. Again, however you linux bunnies do it, I'm sure it'll be cookies and cream.
Cheers brother,
In MySQL, certain words like SELECT
, INSERT
, DELETE
etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.
As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):
Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.
...
If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.
...
The identifier quote character is the backtick ("
`
"):
A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.
You have two options.
The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.
Doing this has a couple of advantages:
It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.
The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.
Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.
If renaming the table or column isn't possible, wrap the offending identifier in backticks (`
) as described in the earlier quote from 10.2 Schema Object Names.
An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):
mysql> CREATE TABLE interval (begin INT, end INT); ERROR 1064 (42000): You have an error in your SQL syntax. near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT); Query OK, 0 rows affected (0.01 sec)
Similarly, the query from the question can be fixed by wrapping the keyword key
in backticks, as shown below:
INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)"; ^ ^

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:
The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?
This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.
In other words, the feature is missing to remove the temptation to use the feature insecurely.
The And
operator will check all conditions in the statement before continuing, whereas the Andalso operator will stop if it knows the condition is false. For example:
if x = 5 And y = 7
Checks if x is equal to 5, and if y is equal to 7, then continues if both are true.
if x = 5 AndAlso y = 7
Checks if x is equal to 5. If it's not, it doesn't check if y is 7, because it knows that the condition is false already. (This is called short-circuiting.)
Generally people use the short-circuiting method if there's a reason to explicitly not check the second part if the first part is not true, such as if it would throw an exception if checked. For example:
If Not Object Is Nothing AndAlso Object.Load()
If that used And
instead of AndAlso
, it would still try to Object.Load()
even if it were nothing
, which would throw an exception.
I got same problem, I tried all above, noting solved my problem. Luckely, I solved the problem this way:
echo $SHELL
Output
/bin/zsh
OR
/bin/bash
If it showing "bash" in output. You have to add env properties in .bashrc file (.bash_profile i did not tried, you can try) or else
It is showing 'zsh' in output. You have to add env properties in .zshrc file, if not exist already you create one no issue.
The CSS :active
state means the active state of the clicked link - the moment when you clicked on it, but not released the mouse button yet, for example. It doesn't know which page you're on and can't apply any styles to the menu items.
To fix your problem you have to create a class and add it manually to the current page's menu:
a.active { color: #f00 }
<ul>
<li><a href="index.php" class="active">HOME</a></li>
<li><a href="two.php">PORTFOLIO</a></li>
<li><a href="three.php">ABOUT</a></li>
<li><a href="four.php">CONTACT</a></li>
<li><a href="five.php">SHOP</a></li>
</ul>
When you import a module (or a member of it) for the first time, the code inside the module is executed sequentially like any other code; e.g., it is not treated any differently that the body of a function. An import
is just a command like any other (assignment, a function call, def
, class
). Assuming your imports occur at the top of the script, then here's what's happening:
World
from world
, the world
script gets executed.world
script imports Field
, which causes the entities.field
script to get executed.entities.post
script because you tried to import Post
entities.post
script causes physics
module to be executed because it tries to import PostBody
physics
tries to import Post
from entities.post
entities.post
module exists in memory yet, but it really doesn't matter. Either the module is not in memory, or the module doesn't yet have a Post
member because it hasn't finished executing to define Post
Post
is not there to be importedSo no, it's not "working further up in the call stack". This is a stack trace of where the error occurred, which means it errored out trying to import Post
in that class. You shouldn't use circular imports. At best, it has negligible benefit (typically, no benefit), and it causes problems like this. It burdens any developer maintaining it, forcing them to walk on egg shells to avoid breaking it. Refactor your module organization.
It's a ProgressDialog, with setIndeterminate(true).
From http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog
ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "",
"Loading. Please wait...", true);
An indeterminate progress bar doesn't actually show a bar, it shows a spinning activity circle thing. I'm sure you know what I mean :)
In C++ (without error checking):
std::string blob = ...; // assume blob is in the string
std::string query = "INSERT INTO foo (blob_column) VALUES (?);";
sqlite3_stmt *stmt;
sqlite3_prepare_v2(db, query, query.size(), &stmt, nullptr);
sqlite3_bind_blob(stmt, 1, blob.data(), blob.size(),
SQLITE_TRANSIENT);
That can be SQLITE_STATIC
if the query will be executed before blob
gets destructed.
Of course you can, say for example, you want to use the DescriptionAttribue
on your enum
values:
using System.ComponentModel.DataAnnotations;
public enum Duration
{
[Description("Eight hours")]
Day,
[Description("Five days")]
Week,
[Description("Twenty-one days")]
Month
}
Now you want to be able to do something like:
Duration duration = Duration.Week;
var description = duration.GetDescription(); // will return "Five days"
Your extension method GetDescription()
can be written as follows:
using System.ComponentModel;
using System.Reflection;
public static string GetDescription(this Enum value)
{
FieldInfo fieldInfo = value.GetType().GetField(value.ToString());
if (fieldInfo == null) return null;
var attribute = (DescriptionAttribute)fieldInfo.GetCustomAttribute(typeof(DescriptionAttribute));
return attribute.Description;
}
.parent { text-align: center; }
.parent > .child { margin: 0 auto; width: 900px; }
For strings containing   I've had to double-decode the string. First decode would turn it into the second pass would correctly decode it to the expected character.
You can use the following code;
var example: String = "Hello World \r\n This is a new line"

You have to pass the CancellationToken
to the Task, which will periodically monitors the token to see whether cancellation is requested.
// CancellationTokenSource provides the token and have authority to cancel the token
CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();
CancellationToken token = cancellationTokenSource.Token;
// Task need to be cancelled with CancellationToken
Task task = Task.Run(async () => {
while(!token.IsCancellationRequested) {
Console.Write("*");
await Task.Delay(1000);
}
}, token);
Console.WriteLine("Press enter to stop the task");
Console.ReadLine();
cancellationTokenSource.Cancel();
In this case, the operation will end when cancellation is requested and the Task
will have a RanToCompletion
state. If you want to be acknowledged that your task has been cancelled, you have to use ThrowIfCancellationRequested
to throw an OperationCanceledException
exception.
Task task = Task.Run(async () =>
{
while (!token.IsCancellationRequested) {
Console.Write("*");
await Task.Delay(1000);
}
token.ThrowIfCancellationRequested();
}, token)
.ContinueWith(t =>
{
t.Exception?.Handle(e => true);
Console.WriteLine("You have canceled the task");
},TaskContinuationOptions.OnlyOnCanceled);
Console.WriteLine("Press enter to stop the task");
Console.ReadLine();
cancellationTokenSource.Cancel();
task.Wait();
Hope this helps to understand better.
The simple version is 0x is a prefix denoting a hexadecimal number, source.
So the value you're computing is after the prefix, in this case 10.
But that is not the number 10. The most significant bit 1
denotes the hex value while 0
denotes the units.
So the simple math you would do is
0x10
1 * 16 + 0 = 16
Note - you use 16 because hex is base 16.
Another example:
0xF7
15 * 16 + 7 = 247
You can get a list of values by searching for a hex table. For instance in this chart notice F corresponds with 15.
This is the simplest and fastest way, for allowing the Number input only.

You can also pass events down into child components with something like this:
<CustomComponent
@keyup.enter="handleKeyUp"
/>
...
<template>
<div>
<input
type="text"
v-on="$listeners"
>
</div>
</template>
<script>
export default {
name: 'CustomComponent',
mounted() {
console.log('listeners', this.$listeners)
},
}
</script>
That works well if you have a pass-through component and want the listeners to go onto a specific element.

Please login as the user "ec2-user" rather than the user "root".
To Answer your question: now AWS make cloning real easy see Launch instance from your Existing Instance

There is a fourth option in addition to the ones in mfulton26's answer.
By using the ?.
operator it is possible to call methods as well as fields without dealing with let
or using local variables.
Some code for context:
var factory: ServerSocketFactory = SSLServerSocketFactory.getDefault();
socket = factory.createServerSocket(port)
socket.close()//smartcast impossible
socket?.close()//Smartcast possible. And works when called
It works with methods, fields and all the other things I tried to get it to work.
So in order to solve the issue, instead of having to use manual casts or using local variables, you can use ?.
to call the methods.
For reference, this was tested in Kotlin 1.1.4-3
, but also tested in 1.1.51
and 1.1.60
. There's no guarantee it works on other versions, it could be a new feature.
Using the ?.
operator can't be used in your case since it's a passed variable that's the problem. The Elvis operator can be used as an alternative, and it's probably the one that requires the least amount of code. Instead of using continue
though, return
could also be used.
Using manual casting could also be an option, but this isn't null safe:
queue.add(left as Node);
Meaning if left has changed on a different thread, the program will crash.
I simply closed the htc sync application completely and tried again. It worked as it was supposed to.
deleteRequest: function (url, Id, bolDeleteReq, callback, errorCallback) {
$.ajax({
url: urlCall,
type: 'DELETE',
data: {"Id": Id, "bolDeleteReq" : bolDeleteReq},
success: callback || $.noop,
error: errorCallback || $.noop
});
}
Note: the use of headers
was introduced in JQuery 1.5.:
A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.
You need to import moment() the function and Moment the class separately in TS.
I found a note in the typescript docs here.
/*~ Note that ES6 modules cannot directly export callable functions
*~ This file should be imported using the CommonJS-style:
*~ import x = require('someLibrary');
So the code to import moment js into typescript actually looks like this:
import { Moment } from 'moment'
....
let moment = require('moment');
...
interface SomeTime {
aMoment: Moment,
}
...
fn() {
...
someTime.aMoment = moment(...);
...
}
i downloaded paramiko full source code from pypi and did
python setup.py install
it worked flawlessly
all default pythondev / openssl /libffi packages are already present in rhel.
downloading rpms have rpm mismatch and more trouble
I agree with other posters that Xcode as a developing environment should include an easy way to debug variables. Well, good news, there IS one!
After searching and not finding a simple answer/tutorial on how to debug variables in Xcode I went to explore with Xcode itself and found this (at least for me) very useful discovery.
In the main screen of Xcode make sure to see the bottom Debug Area by clicking the upper-right corner button showed in the screenshot.
Now set a Breakpoint – the line in your code where you want your program to pause, by clicking the border of your Code Area.
Now in the Debug Area look for this buttons and click the one in the middle. You will notice your area is now divided in two.
Now run your application.
When the first Breakpoint is reached during the execution of your program you will see on the left side all your variables available at that breakpoint.
You can expand the left arrows on the variable for a greater detail. And even use the search field to isolate that variable you want and see it change on real time as you "Step into" the scope of the Breakpoint.
On the right side of your Debug Area you can send to print the variables as you desire using the mouse's right-button click over the desired variable.
As you can see, that contextual menu is full of very interesting debugging options. Such as Watch that has been already suggested with typed commands or even Edit Value… that changes the runtime value of your variable!
Use a Page Viewer webpart and switch from Web Page to Folder. You can the specify the folder you want to display in the Link.
in my case i updated the build.gradle
file and make the classpath
to latest version from 3.5.2
to 3.6.3
dependencies {
classpath("com.android.tools.build:gradle:3.6.3")
}
I know the question was asked 7 years and 9 months ago
but many posted solutions doesn't seem to work, for example using an <iframe>
works only with FireFox
and doesn't work with Chrome
.
Best solution:
The best working solution to open a file download pop-up in JavaScript
is to use a HTML
link element, with no need to append the link element to the document.body
as stated in other answers.
You can use the following function:
function downloadFile(filePath){
var link=document.createElement('a');
link.href = filePath;
link.download = filePath.substr(filePath.lastIndexOf('/') + 1);
link.click();
}
In my application, I am using it this way:
downloadFile('report/xls/myCustomReport.xlsx');
Working Demo:
function downloadFile(filePath) {_x000D_
var link = document.createElement('a');_x000D_
link.href = filePath;_x000D_
link.download = filePath.substr(filePath.lastIndexOf('/') + 1);_x000D_
link.click();_x000D_
}_x000D_
_x000D_
downloadFile("http://www.adobe.com/content/dam/Adobe/en/accessibility/pdfs/accessing-pdf-sr.pdf");
_x000D_
Note:
link.download
attribute so the browser doesn't
open the file in a new tab and fires the download pop-up.Generally, I agree with @kgrittn's advice. Go for it.
But to address your basic question about concat()
: The new function concat()
is useful if you need to deal with null values - and null has neither been ruled out in your question nor in the one you refer to.
If you can rule out null values, the good old (SQL standard) concatenation operator ||
is still the best choice, and @luis' answer is just fine:
SELECT col_a || col_b;
If either of your columns can be null, the result would be null in that case. You could defend with COALESCE
:
SELECT COALESCE(col_a, '') || COALESCE(col_b, '');
But that get tedious quickly with more arguments. That's where concat()
comes in, which never returns null, not even if all arguments are null. Per documentation:
NULL arguments are ignored.
SELECT concat(col_a, col_b);
The remaining corner case for both alternatives is where all input columns are null in which case we still get an empty string ''
, but one might want null instead (at least I would). One possible way:
SELECT CASE
WHEN col_a IS NULL THEN col_b
WHEN col_b IS NULL THEN col_a
ELSE col_a || col_b
END;
This gets more complex with more columns quickly. Again, use concat()
but add a check for the special condition:
SELECT CASE WHEN (col_a, col_b) IS NULL THEN NULL
ELSE concat(col_a, col_b) END;
How does this work?
(col_a, col_b)
is shorthand notation for a row type expression ROW (col_a, col_b)
. And a row type is only null if all columns are null. Detailed explanation:
Also, use concat_ws()
to add separators between elements (ws
for "with separator").
An expression like the one in Kevin's answer:
SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;
is tedious to prepare for null values in PostgreSQL 8.3 (without concat()
). One way (of many):
SELECT COALESCE(
CASE
WHEN $1.zipcode IS NULL THEN $1.city
WHEN $1.city IS NULL THEN $1.zipcode
ELSE $1.zipcode || ' - ' || $1.city
END, '')
|| COALESCE(', ' || $1.state, '');
STABLE
concat()
and concat_ws()
are STABLE
functions, not IMMUTABLE
because they can invoke datatype output functions (like timestamptz_out
) that depend on locale settings.
Explanation by Tom Lane.
This prohibits their direct use in index expressions. If you know that the result is actually immutable in your case, you can work around this with an IMMUTABLE
function wrapper. Example here:
Please follow the following steps.
Enable offline mode : Please check below print screen.
Enable Instant Run : Please check below print screen.

First, create an angular filter using LoDash:
angular.module('myApp').filter('times', function(){
return function(value){
return _.times(value || 0);
}
});
The LoDash times function is capable of handling null, undefined, 0, numbers, and string representation of numbers.
Then, use it in your HTML as this:
<span ng-repeat="i in 5 | times">
<!--DO STUFF-->
</span>
or
<span ng-repeat="i in myVar | times">
<!--DO STUFF-->
</span>
I don't understand the first two answers. I think they must be version-dependent. I cannot reproduce them on MySQLdb 1.2.3, which comes with Ubuntu 14.04LTS. Let's try them. First, we verify that MySQL doesn't accept double-apostrophes:
mysql> select * from methods limit 1;
+----------+--------------------+------------+
| MethodID | MethodDescription | MethodLink |
+----------+--------------------+------------+
| 32 | Autonomous Sensing | NULL |
+----------+--------------------+------------+
1 row in set (0.01 sec)
mysql> select * from methods where MethodID = ''32'';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '9999'' ' at line 1
Nope. Let's try the example that Mandatory posted using the query constructor inside /usr/lib/python2.7/dist-packages/MySQLdb/cursors.py
where I opened "con" as a connection to my database.
>>> search = "test"
>>> "SELECT * FROM records WHERE email LIKE '%s'" % con.literal(search)
"SELECT * FROM records WHERE email LIKE ''test''"
>>>
Nope, the double apostrophes cause it to fail. Let's try Mike Graham's first comment, where he suggests leaving off the apostrophes quoting the %s:
>>> "SELECT * FROM records WHERE email LIKE %s" % con.literal(search)
"SELECT * FROM records WHERE email LIKE 'test'"
>>>
Yep, that will work, but Mike's second comment and the documentation says that the argument to execute (processed by con.literal) must be a tuple (search,)
or a list [search]
. You can try them, but you'll find no difference from the output above.
The best answer is ksg97031's.

In my case, program was not waiting because I was using watcher
command to auto run the program. Manually running the program go run main.go
resulted in "Enter text" and eventually printing to console.
fmt.Print("Enter text: ")
var input string
fmt.Scanln(&input)
fmt.Print(input)
The code you have posted doesn't include a call to mysql_fetch_array()
. However, what is most likely going wrong is that you are issuing a query that returns an error message, in which case the return value from the query function is false
, and attempting to call mysql_fetch_array()
on it doesn't work (because boolean false
is not a mysql result object).
If you look at the documentation for str.split
:
If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns [].
In other words, if you're trying to figure out what to pass to split
to get '\n\tName: Jane Smith'
to ['Name:', 'Jane', 'Smith']
, just pass nothing (or None).
This almost solves your whole problem. There are two parts left.
First, you've only got two fields, the second of which can contain spaces. So, you only want one split, not as many as possible. So:
s.split(None, 1)
Next, you've still got those pesky colons. But you don't need to split on them. At least given the data you've shown us, the colon always appears at the end of the first field, with no space before and always space after, so you can just remove it:
key, value = s.split(None, 1)
key = key[:-1]
There are a million other ways to do this, of course; this is just the one that seems closest to what you were already trying.
In "References", import DAO 3.6 object reference.
private sub showTableData
dim db as dao.database
dim rs as dao.recordset
set db = currentDb
set rs = db.OpenRecordSet("myTable") 'myTable is a MS-Access table created previously
'populate the table
rs.movelast
rs.movefirst
do while not rs.EOF
debug.print(rs!myField) 'myField is a field name in table myTable
rs.movenext 'press Ctrl+G to see debuG window beneath
loop
msgbox("End of Table")
end sub
You can interate data objects like queries and filtered tables in different ways:
Trhough query:
private sub showQueryData
dim db as dao.database
dim rs as dao.recordset
dim sqlStr as string
sqlStr = "SELECT * FROM customers as c WHERE c.country='Brazil'"
set db = currentDb
set rs = db.openRecordset(sqlStr)
rs.movefirst
do while not rs.EOF
debug.print("cust ID: " & rs!id & " cust name: " & rs!name)
rs.movenext
loop
msgbox("End of customers from Brazil")
end sub
You should also look for "Filter" property of the recordset object to filter only the desired records and then interact with them in the same way (see VB6 Help in MS-Access code window), or create a "QueryDef" object to run a query and use it as a recordset too (a little bit more tricky). Tell me if you want another aproach.
I hope I've helped.
Once you have selected the highest value, which is "12" in my example, you can then declare it as integer and increment your value:
$FileList = "1", "2", "11"
$foldername = [int]$FileList[2] + 1
$foldername
from datetime import timedelta
datetime.datetime.now() - datetime.timedelta(0, 900)
Actually 900 is in seconds. Which is equal to 15 minutes. `15*60 = 900`
It depends by the encoding rules followed by your server.
Apple offer this class method, but it don't report wich kind of RCF protocol it follows.
var escapedString = originalString.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!
Following this useful tool you should guarantee the encoding of these chars for your parameters:
In other words, speaking about URL encoding, you should following the RFC 1738 protocol.
And Swift don't cover the encoding of the + char for example, but it works well with these three @ : ? chars.
So, to correctly encoding each your parameter , the .urlHostAllowed
option is not enough, you should add also the special chars as for example:
encodedParameter = parameter.replacingOccurrences(of: "+", with: "%2B")
Hope this helps someone who become crazy to search these informations.
There's a strong chance that the privileges to select from table1 have been granted to a role, and the role has been granted to you. Privileges granted to a role are not available to PL/SQL written by a user, even if the user has been granted the role.
You see this a lot for users that have been granted the dba role on objects owned by sys. A user with dba role will be able to, say, SELECT * from V$SESSION
, but will not be able to write a function that includes SELECT * FROM V$SESSION
.
The fix is to grant explicit permissions on the object in question to the user directly, for example, in the case above, the SYS user has to GRANT SELECT ON V_$SESSION TO MyUser;
Needs to be:
if (document.forms[0].elements["checkAddress"].checked == true)
Assuming you have one form, otherwise use the form name.
As a side note, don't call the element and the function in the same name it can cause weird conflicts.
I find it easier to access it by doing the following:
for (int i = 0; i < Table.Rows.Count-1; i++) //Looping through rows
{
var myValue = Table.Rows[i]["MyFieldName"]; //Getting my field value
}
At the Android 28(Android P)
startActivity
if ((intent.getFlags() & Intent.FLAG_ACTIVITY_NEW_TASK) == 0
&& (targetSdkVersion < Build.VERSION_CODES.N
|| targetSdkVersion >= Build.VERSION_CODES.P)
&& (options == null
|| ActivityOptions.fromBundle(options).getLaunchTaskId() == -1)) {
throw new AndroidRuntimeException(
"Calling startActivity() from outside of an Activity "
+ " context requires the FLAG_ACTIVITY_NEW_TASK flag."
+ " Is this really what you want?");
}
So the best way is add FLAG_ACTIVITY_NEW_TASK
Intent intent = new Intent(context, XXXActivity.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
context.startActivity(intent);
Simplified way (Used only on small arrays because of performance issues. In large arrays you have to make the filter manually via code):
See: https://angular.io/guide/pipes#appendix-no-filterpipe-or-orderbypipe
@Pipe({
name: 'filter'
})
@Injectable()
export class FilterPipe implements PipeTransform {
transform(items: any[], field : string, value : string): any[] {
if (!items) return [];
if (!value || value.length == 0) return items;
return items.filter(it =>
it[field].toLowerCase().indexOf(value.toLowerCase()) !=-1);
}
}
Usage:
<li *ngFor="let it of its | filter : 'name' : 'value or variable'">{{it}}</li>
If you use a variable as a second argument, don't use quotes.
modified_string = string.gsub(/\s+/, ' ').strip
If you include the additional methods file, here's the current file for 1.7: http://ajax.microsoft.com/ajax/jquery.validate/1.7/additional-methods.js
You can use the lettersonly
rule :) The additional methods are part of the zip you download, you can always find the latest here.
Here's an example:
$("form").validate({
rules: {
myField: { lettersonly: true }
}
});
It's worth noting, each additional method is independent, you can include that specific one, just place this before your .validate()
call:
jQuery.validator.addMethod("lettersonly", function(value, element) {
return this.optional(element) || /^[a-z]+$/i.test(value);
}, "Letters only please");
If Color
is something that is specific to just Car
s then that is the way you would limit its scope. If you are going to have another Color
enum that other classes use then you might as well make it global (or at least outside Car
).
It makes no difference. If there is a global one then the local one is still used anyway as it is closer to the current scope. Note that if you define those function outside of the class definition then you'll need to explicitly specify Car::Color
in the function's interface.

If you organize your test cases, that is, follow the same organization like the actual code and also use relative imports for modules in the same package, you can also use the following command format:
python -m unittest mypkg.tests.test_module.TestClass.test_method
# In your case, this would be:
python -m unittest testMyCase.MyCase.testItIsHot

This is not a elegant method, is a very 'low level' implementation of a simple state machine (bitfield state machine), possibly the most anti pythonic mode to resolve this, however re module also implements a too complex state machine to resolve this simple task, so i think this is a good solution.

This is a cheat, but you can do this, send the value to sever side as a parameter
<script>
var myVar = "hello"
window.location.href = window.location.href.replace(/[\?#].*|$/, "?param=" + myVar); //Send the variable to the server side

And from the server side, retrieve the parameter
string myVar = Request.QueryString["param"];
Session["SessionName"] = myVar;

I too was struggling with nested views in Angular.
Once I got a hold of ui-router I knew I was never going back to angular default routing functionality.
Here is an example application that uses multiple levels of views nesting
app.config(function ($stateProvider, $urlRouterProvider,$httpProvider) {
// navigate to view1 view by default
$urlRouterProvider.otherwise("/view1");
$stateProvider
.state('view1', {
url: '/view1',
templateUrl: 'partials/view1.html',
controller: 'view1.MainController'
})
.state('view1.nestedViews', {
url: '/view1',
views: {
'childView1': { templateUrl: 'partials/view1.childView1.html' , controller: 'childView1Ctrl'},
'childView2': { templateUrl: 'partials/view1.childView2.html', controller: 'childView2Ctrl' },
'childView3': { templateUrl: 'partials/view1.childView3.html', controller: 'childView3Ctrl' }
}
})
.state('view2', {
url: '/view2',
})
.state('view3', {
url: '/view3',
})
.state('view4', {
url: '/view4',
});
});
As it can be seen there are 4 main views (view1,view2,view3,view4) and view1 has 3 child views.
This is how I do this in order to work with LINQ.
DateTime date_time_to_compare = DateTime.Now;
//Compare only date parts
context.YourObject.FirstOrDefault(r =>
EntityFunctions.TruncateTime(r.date) == EntityFunctions.TruncateTime(date_to_compare));
If you only use dtOne.Date == dtTwo.Date
it wont work with LINQ (Error: The specified type member 'Date' is not supported in LINQ to Entities)
String text="hello";
StringBuffer sb=new StringBuffer();
char[] ch=text.toCharArray();
for(int i=0;i<ch.length;i++){
if(i==0){
sb.append(Character.toUpperCase(ch[i]));
}
else{
sb.append(ch[i]);
}
}
text=sb.toString();
System.out.println(text);
}
You are incorrectly using the super
and this
keyword. Here is an example of how they work:
class Animal {
public name: string;
constructor(name: string) {
this.name = name;
}
move(meters: number) {
console.log(this.name + " moved " + meters + "m.");
}
}
class Horse extends Animal {
move() {
console.log(super.name + " is Galloping...");
console.log(this.name + " is Galloping...");
super.move(45);
}
}
var tom: Animal = new Horse("Tommy the Palomino");
Animal.prototype.name = 'horseee';
tom.move(34);
// Outputs:
// horseee is Galloping...
// Tommy the Palomino is Galloping...
// Tommy the Palomino moved 45m.
Explanation:
super.name
, this refers to the prototype chain of the object tom
, not the object tom
self. Because we have added a name property on the Animal.prototype
, horseee will be outputted.this.name
, the this
keyword refers to the the tom object itself. move
method of the Animal base class. This method is called from Horse class move method with the syntax super.move(45);
. Using the super
keyword in this context will look for a move
method on the prototype chain which is found on the Animal prototype.Remember TS still uses prototypes under the hood and the class
and extends
keywords are just syntactic sugar over prototypical inheritance.
Did you try:

The object-fit CSS property sets how the content of a replaced element, such as an img or video, should be resized to fit its container.
Magically, object fit also works on a canvas element. No JavaScript needed, and the canvas doesn't stretch, automatically fills to proportion.
canvas {
width: 100%;
object-fit: contain;
}
You can also do:
tree | grep filename
This pipes the output of the tree command to grep for a search. This will only tell you whether the file exists though.
In one of my usecase, I had the scenario of reading a string value preceded by a couple of integer values. I had to use a "for / while loop" to read the values. And none of the above suggestions worked in this case.
Using input.next()
instead of input.nextLine()
fixed the issue. Hope this might be helpful for those dealing with similar scenario.
These are the steps necessary to use OpenCV with Android Studio 1.2:
sdk/java
in the directory you extracted beforeopencv
compileSdkVersion
and buildToolsVersion
to versions you have on your machineAdd compile project(':opencv')
to your app build.gradle
dependencies {
...
compile project(':opencv')
}
Press Sync Project with Gradle Files
you can give some id to the columns and name it uniquely.
Same problem happened to me. So if the service returns the response as a JSON string you have to deserialize the string first, then you will be able to deserialize the object type from it properly:
string json= string.Empty;
using (var streamReader = new StreamReader(response.GetResponseStream(), true))
{
json= new JavaScriptSerializer().Deserialize<string>(streamReader.ReadToEnd());
}
//To deserialize to your object type...
MyType myType;
using (var memoryStream = new MemoryStream())
{
byte[] jsonBytes = Encoding.UTF8.GetBytes(@json);
memoryStream.Write(jsonBytes, 0, jsonBytes.Length);
memoryStream.Seek(0, SeekOrigin.Begin);
using (var jsonReader = JsonReaderWriterFactory.CreateJsonReader(memoryStream, Encoding.UTF8, XmlDictionaryReaderQuotas.Max, null))
{
var serializer = new DataContractJsonSerializer(typeof(MyType));
myType = (MyType)serializer.ReadObject(jsonReader);
}
}

Do this:
date('Y-m-d', strtotime('dd/mm/yyyy'));
But make sure 'dd/mm/yyyy' is the actual date.
If you would like to use a formula, the TRIM
function will do exactly what you're looking for:
+----+------------+---------------------+
| | A | B |
+----+------------+---------------------+
| 1 | =TRIM(B1) | value to trim here |
+----+------------+---------------------+
So to do the whole column...
1) Insert a column
2) Insert TRIM
function pointed at cell you are trying to correct.
3) Copy formula down the page
4) Copy inserted column
5) Paste as "Values"
Should be good to go from there...
Try this backgroundColor: '#00000000'
it will set background color to transparent, it follows #rrggbbaa hex codes
Open up your DevTools and press F1 to access the settings. Look for the console section and check the checkbox for "Log XMLHttpRequests".
Now all of your ajax and other similar requests will be logged in the console.
I prefer this method because it usually allows me to see everything that I'm looking for in the console without having to go to the network tab.
In c# following code insert data into datatable on specified position
DataTable dt = new DataTable();
dt.Columns.Add("SL");
dt.Columns.Add("Amount");
dt.rows.add(1, 1000)
dt.rows.add(2, 2000)
dt.Rows.InsertAt(dt.NewRow(), 3);
var rowPosition = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("SL")] = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("Amount")] = 3000;
In case you have to keep PYTHONPATH for both python2 and python3, you can write alias statements to set the proper PYTHONPATH in your bash_profile:
Hardcode your PYTHONPATH2, and PYTHONPATH3 variables in your ~/.bash_profile, and add the following aliases at the end of it:
alias python='export PYTHONPATH=${PYTHONPATH2};python'
alias python3='export PYTHONPATH=${PYTHONPATH3};python3'
My python
(refers to python2) as I use python2 more often.
Little addition to Jason's answer:
ToShortDateString()
is culture-sensitive.From MSDN:
The string returned by the ToShortDateString method is culture-sensitive. It reflects the pattern defined by the current culture's DateTimeFormatInfo object. For example, for the en-US culture, the standard short date pattern is "M/d/yyyy"; for the de-DE culture, it is "dd.MM.yyyy"; for the ja-JP culture, it is "yyyy/M/d". The specific format string on a particular computer can also be customized so that it differs from the standard short date format string.
That's mean it's better to use the ToString()
method and define format explicitly (as Jason said). Although if this string appeas in UI the ToShortDateString()
is a good solution because it returns string which is familiar to a user.
DateTime.Today
.How about:
void rmdup(int *array, int length)
{
int *current , *end = array + length - 1;
for ( current = array + 1; array < end; array++, current = array + 1 )
{
while ( current <= end )
{
if ( *current == *array )
{
*current = *end--;
}
else
{
current++;
}
}
}
}
Should be O(n^2) or less.
I used a BoxLayout
and set its second parameter as BoxLayout.Y_AXIS
and it worked for me:
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
Your values
object is obviously an Object[]
containing a String[]
containing the values.
String[] stringValues = (String[])values[0];
Turning off my VPN resolved the issue.
The answer above did not work for me (python 3.6, Anaconda, pandas 0.20.3). It worked with
conda install -c anaconda pandas
Unfortunately I do not know how to help with Eclipse.
First make sure that abc.xml
is being copied to your output directory. Then you should use getResourceAsStream()
:
InputStream inputStream =
Thread.currentThread().getContextClassLoader().getResourceAsStream("test/resources/abc.xml");
Once you have the InputStream, you just need to convert it into a string. This resource spells it out: http://www.kodejava.org/examples/266.html. However, I'll excerpt the relevent code:
public String convertStreamToString(InputStream is) throws IOException {
if (is != null) {
Writer writer = new StringWriter();
char[] buffer = new char[1024];
try {
Reader reader = new BufferedReader(
new InputStreamReader(is, "UTF-8"));
int n;
while ((n = reader.read(buffer)) != -1) {
writer.write(buffer, 0, n);
}
} finally {
is.close();
}
return writer.toString();
} else {
return "";
}
}
A multidimensional array creates a nice linear memory layout while a jagged array implies several extra levels of indirection.
Looking up the value jagged[3][6]
in a jagged array var jagged = new int[10][5]
works like this: Look up the element at index 3 (which is an array) and look up the element at index 6 in that array (which is a value). For each dimension in this case, there's an additional look up (this is an expensive memory access pattern).
A multidimensional array is laid out linearly in memory, the actual value is found by multiplying together the indexes. However, given the array var mult = new int[10,30]
, the Length
property of that multidimensional array returns the total number of elements i.e. 10 * 30 = 300.
The Rank
property of a jagged array is always 1, but a multidimensional array can have any rank. The GetLength
method of any array can be used to get the length of each dimension. For the multidimensional array in this example mult.GetLength(1)
returns 30.
Indexing the multidimensional array is faster. e.g. given the multidimensional array in this example mult[1,7]
= 30 * 1 + 7 = 37, get the element at that index 37. This is a better memory access pattern because only one memory location is involved, which is the base address of the array.
A multidimensional array therefore allocates a continuous memory block, while a jagged array does not have to be square, e.g. jagged[1].Length
does not have to equal jagged[2].Length
, which would be true for any multidimensional array.
Performance wise, multidimensional arrays should be faster. A lot faster, but due to a really bad CLR implementation they are not.

The first row are timings of jagged arrays, the second shows multidimensional arrays and the third, well that's how it should be. The program is shown below, FYI this was tested running mono. (The windows timings are vastly different, mostly due to the CLR implementation variations).
On windows, the timings of the jagged arrays are greatly superior, about the same as my own interpretation of what multidimensional array look up should be like, see 'Single()'. Sadly the windows JIT-compiler is really stupid, and this unfortunately makes these performance discussions difficult, there are too many inconsistencies.
These are the timings I got on windows, same deal here, the first row are jagged arrays, second multidimensional and third my own implementation of multidimensional, note how much slower this is on windows compared to mono.

Following up on Mat's answer (use Cygwin), here are some detailed instructions for : installing gcc on Windows The packages you want are gcc, gdb and make. Cygwin installer lets you install additional packages if you need them.
It appears to be a known issue.

Many IN queries can be re-written as (left outer) joins and an IS (NOT) NULL of some sort. for example
SELECT * FROM FOO WHERE ID IN (SELECT ID FROM FOO2)
can be re-written as
SELECT FOO.* FROM FOO JOIN FOO2 ON FOO.ID=FOO2.ID
or
SELECT * FROM FOO WHERE ID NOT IN (SELECT ID FROM FOO2)
can be
SELECT FOO.* FROM FOO
LEFT OUTER JOIN FOO2
ON FOO.ID=FOO2.ID WHERE FOO.ID IS NULL
The following complete example will read an existing server.xml
file from the current directory, append a new Server and re-write the file to server.xml
. It does not work without an existing .xml file, so you will need to modify the code to handle that case.
import java.util.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;
public class AddXmlNode {
public static void main(String[] args) throws Exception {
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse("server.xml");
Element root = document.getDocumentElement();
Collection<Server> servers = new ArrayList<Server>();
servers.add(new Server());
for (Server server : servers) {
// server elements
Element newServer = document.createElement("server");
Element name = document.createElement("name");
name.appendChild(document.createTextNode(server.getName()));
newServer.appendChild(name);
Element port = document.createElement("port");
port.appendChild(document.createTextNode(Integer.toString(server.getPort())));
newServer.appendChild(port);
root.appendChild(newServer);
}
DOMSource source = new DOMSource(document);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
StreamResult result = new StreamResult("server.xml");
transformer.transform(source, result);
}
public static class Server {
public String getName() { return "foo"; }
public Integer getPort() { return 12345; }
}
}
Example server.xml file:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Servers>
<server>
<name>something</name>
<port>port</port>
</server>
</Servers>
The main change to your code is not creating a new "root" element. The above example just uses the current root node from the existing server.xml
and then just appends a new Server element and re-writes the file.
General rule is that you want packages from require-dev section only in development (dev) environments, for example local environment.
Packages in require-dev section are packages which help you debug app, run tests etc.
At staging and production environment you probably want only packages from require section.
But anyway you can run composer install --no-dev and composer update --no-dev on any environment, command will install only packages from required section not from require-dev, but probably you want to run this only at staging and production environments not on local.
Theoretically you can put all packages in require section and nothing will happened, but you don't want developing packages at production environment because of the following reasons :
Some good candidates for require-dev are :
"filp/whoops": "^2.0",
"fzaninotto/faker": "^1.4",
"mockery/mockery": "^1.0",
"nunomaduro/collision": "^2.0",
"phpunit/phpunit": "^7.0"
you can see what above packages are doing and you will see why you don't need them on production.
See more here : https://getcomposer.org/doc/04-schema.md
Not an OP direct response, but I thought I would jimmy in here responding to the the OP's ERROR messsage, which may point you in another direction entirely!
All these answers are referring to an overall ORDER BY once the record set has been retrieved and you sort the lot.
What if you want to ORDER BY each portion of the UNION independantly, and still have them "joined" in the same SELECT?
SELECT pass1.* FROM
(SELECT TOP 1000 tblA.ID, tblA.CustomerName
FROM TABLE_A AS tblA ORDER BY 2) AS pass1
UNION ALL
SELECT pass2.* FROM
(SELECT TOP 1000 tblB.ID, tblB.CustomerName
FROM TABLE_B AS tblB ORDER BY 2) AS pass2
Note the TOP 1000 is an arbitary number. Use a big enough number to capture all of the data you require.
Boost.Regex is very good and is slated to become part of the C++0x standard (it's already in TR1).
Personally, I find Boost.Xpressive much nicer to work with. It is a header-only library and it has some nice features such as static regexes (regexes compiled at compile time).
Update: If you're using a C++11 compliant compiler (gcc 4.8 is NOT!), use std::regex unless you have good reason to use something else.
https://github.com/networknt/jsontoken
This is a fork of original google jsontoken
It has not been updated since Sep 11, 2012 and depends on some old packages.
What I have done:
Convert from Joda time to Java 8 time. So it requires Java 8.
Covert Json parser from Gson to Jackson as I don't want to include two Json parsers to my projects.
Remove google collections from dependency list as it is stopped long time ago.
Fix thread safe issue with Java Mac.doFinal call.
All existing unit tests passed along with some newly added test cases.
Here is a sample to generate token and verify the token. For more information, please check https://github.com/networknt/light source code for usage.
I am the author of both jsontoken and Omni-Channel Application Framework.
I copied and pasted this into my .vimrc file:
" size of a hard tabstop
set tabstop=4
" always uses spaces instead of tab characters
set expandtab
" size of an "indent"
set shiftwidth=4
The first 2 settings mean that when I press Tab I get 4 spaces.
The third setting means that when I do V>
(i.e. visual and indent) I also get 4 spaces.
Not as comprehensive as the accepted answer but it might help people who just want something to copy and paste.
When you make the call to gcc it should say
g++ -Wall -I/home/alwin/Development/Calculator/ -L/opt/lib main.cpp -lcalc -o calculator
not -libcalc.so
I have a similar problem with auto-generated makes.
You can create a soft link from your compile directory to the library directory. Then the library becomes "local".
cd /compile/directory
ln -s /path/to/libcalc.so libcalc.so
after I add the property:
<prop key="hibernate.current_session_context_class">thread</prop>
I get the exception like:
org.hibernate.HibernateException: createQuery is not valid without active transaction
org.hibernate.HibernateException: save is not valid without active transaction.
so I think setting that property is not a good solution.
finally I solve "No Hibernate Session bound to thread" problem :
1.<!-- <prop key="hibernate.current_session_context_class">thread</prop> -->
2.add <tx:annotation-driven />
to servlet-context.xml or dispatcher-servlet.xml
3.add @Transactional after @Service and @Repository
Just do the following for Version 44.0.2403.155 dev-m
Privacy -->Content settings -->Do not allow any site to run JavaScript
Problem Solved
// suppose that we have a test.txt at E:\
string filePath = @"E:\test.txt";
if (!File.Exists(filePath))
{
return;
}
// combine the arguments together
// it doesn't matter if there is a space after ','
string argument = "/select, \"" + filePath +"\"";
System.Diagnostics.Process.Start("explorer.exe", argument);

Use "
instead of "
to escape it.
web.config is an XML file so you should use XML escaping.
connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"
See this forum thread.
Update:
"
should work, but as it doesn't, have you tried some of the other string escape sequences for .NET? \"
and ""
?
Update 2:
Try single quotes for the connectionString:
connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'
Or:
connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'
Update 3:
From MSDN (SqlConnection.ConnectionString Property):
To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks.
So:
connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"
The issue is not with web.config, but the format of the connection string. In a connection string, if you have a "
in a value (of the key-value pair), you need to enclose the value in '
. So, while Password=somepass"word
does not work, Password='somepass"word'
does.

"Gets the CultureInfo that represents the culture installed with the operating system."
To set it as default language for thread use :

Just a note: for Anaconda install packages command:
I should like to take a step back and a modern look at this 10 years old question. The classes mentioned, Date
and XMLGregorianCalendar
, are old now. I challenge the use of them and offer alternatives.
Date
was always poorly designed and is more than 20 years old. This is simple: don’t use it.XMLGregorianCalendar
is old too and has an old-fashioned design. As I understand it, it was used for producing dates and times in XML format for XML documents. Like 2009-05-07T19:05:45.678+02:00
or 2009-05-07T17:05:45.678Z
. These formats agree well enough with ISO 8601 that the classes of java.time, the modern Java date and time API, can produce them, which we prefer.For many (most?) purposes the modern replacement for a Date
will be an Instant
. An Instant
is a point in time (just as a Date
is).
Instant yourInstant = // ...
System.out.println(yourInstant);
An example output from this snippet:
2009-05-07T17:05:45.678Z
It’s the same as the latter of my example XMLGregorianCalendar
strings above. As most of you know, it comes from Instant.toString
being implicitly called by System.out.println
. With java.time, in many cases we don’t need the conversions that in the old days we made between Date
, Calendar
, XMLGregorianCalendar
and other classes (in some cases we do need conversions, though, I am showing you a couple in the next section).
Neither a Date
nor in Instant
has got a time zone nor a UTC offset. The previously accepted and still highest voted answer by Ben Noland uses the JVMs current default time zone for selecting the offset of the XMLGregorianCalendar
. To include an offset in a modern object we use an OffsetDateTime
. For example:
ZoneId zone = ZoneId.of("America/Asuncion");
OffsetDateTime dateTime = yourInstant.atZone(zone).toOffsetDateTime();
System.out.println(dateTime);
2009-05-07T13:05:45.678-04:00
Again this conforms with XML format. If you want to use the current JVM time zone setting again, set zone
to ZoneId.systemDefault()
.
There are more ways to convert Instant
to XMLGregorianCalendar
. I will present a couple, each with its pros and cons. First, just as an XMLGregorianCalendar
produces a string like 2009-05-07T17:05:45.678Z
, it can also be built from such a string:
String dateTimeString = yourInstant.toString();
XMLGregorianCalendar date2
= DatatypeFactory.newInstance().newXMLGregorianCalendar(dateTimeString);
System.out.println(date2);
2009-05-07T17:05:45.678Z
Pro: it’s short and I don’t think it gives any surprises. Con: To me it feels like a waste formatting the instant into a string and parsing it back.
ZonedDateTime dateTime = yourInstant.atZone(zone);
GregorianCalendar c = GregorianCalendar.from(dateTime);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);
System.out.println(date2);
2009-05-07T13:05:45.678-04:00
Pro: It’s the official conversion. Controlling the offset comes naturally. Con: It goes through more steps and is therefore longer.
If you got an old-fashioned Date
object from a legacy API that you cannot afford to change just now, convert it to Instant
:
Instant i = yourDate.toInstant();
System.out.println(i);
Output is the same as before:
2009-05-07T17:05:45.678Z
If you want to control the offset, convert further to an OffsetDateTime
in the same way as above.
If you’ve got an old-fashioned Date
and absolutely need an old-fashioned XMLGregorianCalendar
, just use the answer by Ben Noland.
I was struggling with this, my app was installing but not complete (almost 60% I can say) in iOS8, but in iOS7.1 it was working as expected. The error message popped was:
"Cannot install at this time".
Finally Zillan's link helped me to get apple documentation. So, check:
ax.init.itunes.apple.com
is not getting blocked by your firewall/proxy (Just type this address in safari, a blank page must load). As soon as I changed the proxy it installed completely. Hope it will help someone.
I have come to point out the answer nobody seems to see here. You can fullfill all requests you have made with pure CSS and it's very simple. Just use Media Queries. Media queries can check the orientation of the user's screen, or viewport. Then you can style your images depending on the orientation.
Just set your default CSS on your images like so:
img {
width:auto;
height:auto;
max-width:100%;
max-height:100%;
}
Then use some media queries to check your orientation and that's it!
@media (orientation: landscape) { img { height:100%; } }
@media (orientation: portrait) { img { width:100%; } }
You will always get an image that scales to fit the screen, never loses aspect ratio, never scales larger than the screen, never clips or overflows.
To learn more about these media queries, you can read MDN's specs.
To center your image horizontally and vertically, just use the flex box model. Use a parent div
set to 100% width and height, like so:
div.parent {
display:flex;
position:fixed;
left:0px;
top:0px;
width:100%;
height:100%;
justify-content:center;
align-items:center;
}
With the parent div's display
set to flex
, the element is now ready to use the flex box model. The justify-content
property sets the horizontal alignment of the flex items. The align-items
property sets the vertical alignment of the flex items.
I too had wanted these exact requirements and had scoured the web for a pure CSS solution. Since none of the answers here fulfilled all of your requirements, either with workarounds or settling upon sacrificing a requirement or two, this solution really is the most straightforward for your goals; as it fulfills all of your requirements with pure CSS.
EDIT: The accepted answer will only appear to work if your images are large. Try using small images and you will see that they can never be larger than their original size.
I thought perf stat

CPU7 195 cpu-migrations (100.00%)
The left column is the specific CPU index and the right most column is the usage of the CPU. If you don't specify the --no-aggr
option, the result will aggregated together. The --pid=pid
option will help if you want to monitor a running process.
Try -a --per-core
or -a perf-socket
too, which will present more classified information.
More about usage of perf stat
can be seen in this tutorial: perf cpu statistic, also perf help stat
will help on the meaning of the options.
Here is a solution that doesn't use a loop and uses the Android API only:
InputStream inputStreamObject = PositionKeeperRequestTest.class.getResourceAsStream(jsonFileName);
byte[] data = new byte[inputStreamObject.available()];
if(inputStreamObject.read(data) == data.length) {
JSONObject jsonObject = new JSONObject(new String(data));
}
How just spotted here the problem is that you have to wait that the programs that you run from your script finish their jobs.
If in your script you run program in background you can try something more.
In general a call to sync
before you exit allows to flush file system buffers and can help a little.
If in the script you start some programs in background (&
), you can wait that they finish before you exit from the script. To have an idea about how it can function you can see below
#!/bin/bash
#... some stuffs ...
program_1 & # here you start a program 1 in background
PID_PROGRAM_1=${!} # here you remember its PID
#... some other stuffs ...
program_2 & # here you start a program 2 in background
wait ${!} # You wait it finish not really useful here
#... some other stuffs ...
daemon_1 & # We will not wait it will finish
program_3 & # here you start a program 1 in background
PID_PROGRAM_3=${!} # here you remember its PID
#... last other stuffs ...
sync
wait $PID_PROGRAM_1
wait $PID_PROGRAM_3 # program 2 is just ended
# ...
Since wait
works with jobs as well as with PID
numbers a lazy solution should be to put at the end of the script
for job in `jobs -p`
do
wait $job
done
More difficult is the situation if you run something that run something else in background because you have to search and wait (if it is the case) the end of all the child process: for example if you run a daemon probably it is not the case to wait it finishes :-).
Note:
wait ${!} means "wait till the last background process is completed" where $!
is the PID of the last background process. So to put wait ${!}
just after program_2 &
is equivalent to execute directly program_2
without sending it in background with &
From the help of wait
:
Syntax
wait [n ...]
Key
n A process ID or a job specification
I think the short answer is no. For a more generic case in n
dimensions, I came up with this:
# For 2-dimensional data, 4 values
a = np.array([[0, 1, 2], [3, 2, 1]])
z = np.zeros(list(a.shape) + [4])
z[list(np.indices(z.shape[:-1])) + [a]] = 1
I am wondering if there is a better solution -- I don't like that I have to create those lists in the last two lines. Anyway, I did some measurements with timeit
and it seems that the numpy
-based (indices
/arange
) and the iterative versions perform about the same.

I've had the same exact problem in that I installed Anaconda because a python script I want to use relies on pandas, and that after so doing, python still returned the same comment that "pandas module is missing" or something to that effect.
When I typed "python" to see which python was being called, I found it was still accessing the older version of python 2.7, even though when I installed Anaconda the installer asked (and I agreed) that it would make its python the default python on my machine (PC running Windows 7).
I tried to find if there is a CONFIG.SYS file on the PC, but gave up after searching in various places (If anyone knows, please tell me). I got around the problem by writing a one-line batch script named python2.bat that called the Anaconda2 version of python, which then worked. However, it would clearly be better to change the CONFIG.SYS or whatever the PC uses to decide which version of python to call.
As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.
To answer your specific questions:
echo date('Y-m-d H:i:s.') . gettimeofday()['usec'];
output:
2016-11-19 15:12:34.346351
If you use webpack devServer the simplest way is to set disableHostCheck, check webpack doc like this
devServer: {
contentBase: path.join(__dirname, './dist'),
compress: true,
host: 'localhost',
// host: '0.0.0.0',
port: 8080,
disableHostCheck: true //for ngrok
},
Try using:
conda install python-graphviz
The graphviz executable sit on a different path from your conda directory, if you use pip install graphviz
.
There is the question whether we want to differentiate between cases:
"phone" : "" = the value is empty
"phone" : null = the value for "phone" was not set yet
If we want differentiate I would use null for this. Otherwise we would need to add a new field like "isAssigned" or so. This is an old Database issue.
To expand on a few of the answers here, yes you could remove the following block from your .csproj file:
<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
and this fixes the issue, however in my case, I noticed that I had additional references to the .NET.Compilers and .CodeDom.Providers with different versions:
<Error Condition="!Exists('..\packages\Microsoft.Net.Compilers.1.0.0
<Error Condition="!Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\
<Error Condition="!Exists('..\packages\Microsoft.Net.Compilers.2.0.1
<Error Condition="!Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.3\
When my packages.config only referenced the following:
<package id="Microsoft.Net.Compilers" version="2.0.1"
<package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="1.0.3"
Removing the 1.0.0 items from the .csproj file fixed the issue.
REST stands for REpresentational State Transfer and goes a little something like this:
We have a bunch of uniquely addressable 'entities' that we want made available via a web application. Those entities each have some identifier and can be accessed in various formats. REST defines a bunch of stuff about what GET, POST, etc mean for these purposes.
the basic idea with REST is that you can attach a bunch of 'renderers' to different entities so that they can be available in different formats easily using the same HTTP verbs and url formats.
For more clarification on what RESTful means and how it is used google rails. Rails is a RESTful framework so there's loads of good information available in its docs and associated blog posts. Worth a read even if you arent keen to use the framework. For example: http://www.sitepoint.com/restful-rails-part-i/
RESTless means not restful. If you have a web app that does not adhere to RESTful principles then it is not RESTful
this prototype:
int execlp(const char *file, const char *arg, ...);
Says that execlp ìs a variable argument function. It takes 2 const char *
. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char *
- all these are C strings (and the last argument must be a NULL pointer)
So, the file
argument is the path name of an executable file to be executed. arg
is the string we want to appear as argv[0]
in the executable. By convention, argv[0]
is just the file name of the executable, normally it's set to the same as file
.
The ...
are now the additional arguments to give to the executable.
Say you run this from a commandline/shell:
$ ls
That'd be execlp("ls", "ls", (char *)NULL);
Or if you run
$ ls -l /
That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);
So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);
Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:
$ ls -l /bin/??
Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.
What you want to run is:
$ /bin/sh -c "ls -l /bin/??"
This becomes
execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);
Side note:
The /bin/??
is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did
execlp("ls","ls", "-l", "/bin/??", (char *)NULL);
Probably nothing would happen (unless there's a file actually named /bin/??
) as there's no shell that interprets and expands /bin/??

I have been trying out the different packages including the function:
install.packages ("prettyR")
library (prettyR)
delimit.table (Corrvar,"Name the csv.csv")
## Corrvar
is a name of an object from an output I had on scaled variables to run a regression.
However I tried this same code for an output from another analysis (occupancy models model selection output) and it did not work. And after many attempts and exploration I:
In the "Data" vignette, click on "Text to column"
Select Delimited option, click next
Tick space box in "Separator", click next
Click Finalize (End)
Your output now should be in a form you can manipulate easy in excel. So perhaps not the fanciest option but it does the trick if you just want to explore your data in another way.
PS. If the labels in excel are not the exact one it is because Im translating the lables from my spanish excel.
To use sed
on MacOS, do this:
sed -i.bak $'s/\r//' <filename>
Explanation: The $'STRING'
syntax here pertains to the bash shell. Macs don't treat \r
as special character. By quoting the command string in $''
you're telling the shell to replace \r
with the actual \r
character specified in the ANSI-C standard.
That would only happen if PostCode
is missing a space.
You could add conditionality such that all of PostCode
is retrieved should a space not be found as follows
select SUBSTRING(PostCode, 1 ,
case when CHARINDEX(' ', PostCode ) = 0 then LEN(PostCode)
else CHARINDEX(' ', PostCode) -1 end)
What you may want to do is include a script on all pages that does the following ... 1. find the youtube-iframe : searching for it by width and height by title or by finding www.youtube.com in its source. You can do that by ... - looping through the window.frames by a for-in loop and then filter out by the properties
inject jscript in the iframe of the current page adding the onYoutubePlayerReady must-include-function http://shazwazza.com/post/Injecting-JavaScript-into-other-frames.aspx
Add the event listeners etc..
Hope this helps
If you are using Gradle add this:
dependencies {
...
compile "org.slf4j:slf4j-simple:1.7.9"
...
}
You can do in this way:
Integer i = 1;
new BigInteger("" + i);
I had something similar happen to me just recently. I updated my iPhone to 8.1.3, and started getting the 'application could not be verified' error message from Xcode on an app that installed just fine on the same iOS device from the same Mac just a few days ago.
I deleted the app from the device, restarted Xcode, and the app subsequently installed on the device just fine without any error message. Not sure if deleting the app was the fix, or the problem was due to "the phase of the moon".
For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:
"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
<sheets>
<sheet name="MySheet1" sheetId="1" r:id="rId1" />
<sheet name="MySheet2" sheetId="2" r:id="rId2" />
</sheets>
</workbook>
The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" ?>
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
<sheetData>
<row r="1">
<c r="A1">
<v>100</v>
</c>
</row>
</sheetData>
</worksheet>
"
Detection of cell encodings:
RandomStringUtils has a provision to create a string from given input size. Cant comment on the speed, but its a one liner.
RandomStringUtils.random(5,"\t");
creates an output
\t\t\t\t\t
preferable if you dont want to see \0 in your code.
If there are large number of lines you want to comment out then it will be better if you can make multi line comments rather than commenting out every line.
See this post by Rob van der Woude on comment blocks:
The batch language doesn't have comment blocks, though there are ways to accomplish the effect.
GOTO EndComment1 This line is comment. And so is this line. And this one... :EndComment1
You can use
GOTO
Label and :Label for making block comments.Or, If the comment block appears at the end of the batch file, you can write
EXIT
at end of code and then any number of comments for your understanding.@ECHO OFF REM Do something • • REM End of code; use GOTO:EOF instead of EXIT for Windows NT and later EXIT Start of comment block at end of batch file This line is comment. And so is this line. And this one...
Just use dynamic
as the argument:
var list = new List<dynamic>();
I highly doubt it. You might want to use DTS/SSIS to do this as Levi says. One think that you might want to do is start the process without actually importing the data. Just do enough to get the basic table structures together. Then you are going to want to change around the resulting table structure, because whatever structure tat will likely be created will be shaky at best.
You might also have to take this a step further and create a staging area that takes in all the data first n a string (varchar) form. Then you can create a script that does validation and conversion to get it into the "real" database, because the two databases don't always work well together, especially when dealing with dates.
Try using a single quote instead of double quotes along with -g
Following scenario worked for me
curl -g -d '{"collection":[{"NumberOfParcels":1,"Weight":1,"Length":1,"Width":1,"Height":1}]}" -H "Accept: application/json" -H "Content-Type: application/json" --user [email protected]:123456 -X POST https://yoururl.com
WITH
curl -g -d "{'collection':[{'NumberOfParcels':1,'Weight':1,'Length':1,'Width':1,'Height':1}]}" -H "Accept: application/json" -H "Content-Type: application/json" --user [email protected]:123456 -X POST https://yoururl.com
This especially resolved my error curl command error : bad url colon is first character
It's time I post an answer about RVO, me too...
If you return an object by value, the compiler often optimizes this so it doesn't get constructed twice, since it's superfluous to construct it in the function as a temporary and then copy it. This is called return value optimization: the created object will be moved instead of being copied.
I know this question is old but the accepted answer does not work anymore and since this is the fist link on google search i'll tell how i solved this problem.
for eclipse using ubuntu:
go to Window->Preferences->Ant->Runtime->Select Ant_Home_Entries and click on add external jars then find in file explorer where your jdk is (default is in /usr/lib/jvm/) and in the lib folder of your jdk you will find the tool.jar. select this one and click apply.
try to build your project and things should work!
note: i hadn't used ant for a long time but needed it for ycsb couchbase workload generator (http://www.couchbase.com/wiki/display/couchbase/Load+Generator+Setup) if anyone is/was stuck on this.
Use Column.DefaultCellStyle.Format property or set it in designer
You have to disable or enable the individual elements. This is how I did it:
$(':input').keydown(function(e){
var allowTab = true;
var id = $(this).attr('name');
// insert your form fields here -- (:'') is required after
var inputArr = {username:'', email:'', password:'', address:''}
// allow or disable the fields in inputArr by changing true / false
if(id in inputArr) allowTab = false;
if(e.keyCode==9 && allowTab==false) e.preventDefault();
});
resolve the url like this href="<%=ResolveUrl("~/favicon.ico")%>"
Those are probably timestamps in seconds and not in milliseconds which is required for the java new Date(long) constructor. Just multiply them by 1000 and you should be allright.
For my answer, it is worth remembering that the TPL (Task-Parallel-Library), Task
class and TaskStatus
enumeration were introduced prior to the async-await keywords and the async-await keywords were not the original motivation of the TPL.
In the context of methods marked as async
, the resulting Task
is not a Task
representing the execution of the method, but a Task
for the continuation of the method.
This is only able to make use of a few possible states:
I understand that Running
could appear to have been a better default than WaitingForActivation
, however this could be misleading, as the majority of the time, an async method being executed is not actually running (i.e. it may be await
-ing something else). The other option may have been to add a new value to TaskStatus
, however this could have been a breaking change for existing applications and libraries.
All of this is very different to when making use of Task.Run
which is a part of the original TPL, this is able to make use of all the possible values of the TaskStatus
enumeration.
If you wish to keep track of the status of an async method, take a look at the IProgress(T)
interface, this will allow you to report the ongoing progress. This blog post, Async in 4.5: Enabling Progress and Cancellation in Async APIs will provide further information on the use of the IProgress(T)
interface.
If you are using Netty and want to use a map with primitive int type keys, you can use its IntObjectHashMap

With Olivier's solution, during update statements you may run into:
com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'created' cannot be null
To solve this, add updatable=false to the @Column annotation of "created" attribute:
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "created", nullable = false, updatable=false)
private Date created;
You could use toPrecision() and toFixed() methods of Number type. Check this link How can I format numbers as money in JavaScript?

Java 8 Collection has a nice method called removeIf that makes things easier and safer. From the API docs:
default boolean removeIf(Predicate<? super E> filter)
Removes all of the elements of this collection that satisfy the given predicate.
Errors or runtime exceptions thrown during iteration or by the predicate
are relayed to the caller.
Interesting note:
The default implementation traverses all elements of the collection using its iterator().
Each matching element is removed using Iterator.remove().
Yes. As the session ID is either transported over the URL (document.location.href
) or via a cookie (document.cookie
), you could check both for the presence of a session ID.
Within the dplyr world, try:
select(iris,contains("Sepal"))
See the Selection section in ?select
for numerous other helpers like starts_with

I used ADAL.NET/ Microsoft Identity Platform to achieve this. The advantage of using it was that we get a nice wrapper around the code to acquire AccessToken
and we get additional features like Token Cache
out-of-the-box. From the documentation:
Why use ADAL.NET ?
ADAL.NET V3 (Active Directory Authentication Library for .NET) enables developers of .NET applications to acquire tokens in order to call secured Web APIs. These Web APIs can be the Microsoft Graph, or 3rd party Web APIs.
Here is the code snippet:
// Import Nuget package: Microsoft.Identity.Client
public class AuthenticationService
{
private readonly List<string> _scopes;
private readonly IConfidentialClientApplication _app;
public AuthenticationService(AuthenticationConfiguration authentication)
{
_app = ConfidentialClientApplicationBuilder
.Create(authentication.ClientId)
.WithClientSecret(authentication.ClientSecret)
.WithAuthority(authentication.Authority)
.Build();
_scopes = new List<string> {$"{authentication.Audience}/.default"};
}
public async Task<string> GetAccessToken()
{
var authenticationResult = await _app.AcquireTokenForClient(_scopes)
.ExecuteAsync();
return authenticationResult.AccessToken;
}
}
Usually, only the endpoint that issues an 'active close' should go into TIME_WAIT state. So, if possible, have your clients issue the active close which will leave the TIME_WAIT on the client and NOT on the server.
See here: http://www.serverframework.com/asynchronousevents/2011/01/time-wait-and-its-design-implications-for-protocols-and-scalable-servers.html and http://www.isi.edu/touch/pubs/infocomm99/infocomm99-web/ for details (the later also explains why it's not always possible due to protocol design that doesn't take TIME_WAIT into consideration).
The key is to give the anchor links a display property of "block" and a width property of 100%.
Making list-items clickable (example):
HTML:
<ul>
<li><a href="">link1</a></li>
<li><a href="">link2</a></li>
<li><a href="">link3</a></li>
</ul>
CSS:
ul {
list-style-type: none;
margin: 0;
padding: 0;
}
ul li a {
display: block;
width: 100%;
text-decoration: none;
padding: 5px;
}
ul li a:hover {
background-color: #ccc;
}
You could hack your own, not relying on jQuery plugins... though you'd need to keep track externally (in JS) of selected items since the transition would remove the selected state info:
<head>
<script type='text/javascript' src='http://code.jquery.com/jquery-1.4.4.min.js'></script>
<script type='text/javascript'>
$(window).load(function(){
$('#transactionType').focusin(function(){
$('#transactionType').attr('multiple', true);
});
$('#transactionType').focusout(function(){
$('#transactionType').attr('multiple', false);
});
});>
</script>
</head>
<body>
<select id="transactionType">
<option value="ALLOC">ALLOC</option>
<option value="LOAD1">LOAD1</option>
<option value="LOAD2">LOAD2</option>
</select>
</body>
TypeA[] array = (TypeA[]) a.toArray();
After i iterations the first i elements are ordered.
In each iteration the next element is bubbled through the sorted section until it reaches the right spot:
sorted | unsorted
1 3 5 8 | 4 6 7 9 2
1 3 4 5 8 | 6 7 9 2
The 4 is bubbled into the sorted section
Pseudocode:
for i in 1 to n
for j in i downto 2
if array[j - 1] > array[j]
swap(array[j - 1], array[j])
else
break
After i iterations the last i elements are the biggest, and ordered.
In each iteration, sift through the unsorted section to find the maximum.
unsorted | biggest
3 1 5 4 2 | 6 7 8 9
1 3 4 2 | 5 6 7 8 9
The 5 is bubbled out of the unsorted section
Pseudocode:
for i in 1 to n
for j in 1 to n - i
if array[j] > array[j + 1]
swap(array[j], array[j + 1])
Note that typical implementations terminate early if no swaps are made during one of the iterations of the outer loop (since that means the array is sorted).
In insertion sort elements are bubbled into the sorted section, while in bubble sort the maximums are bubbled out of the unsorted section.
You're getting that error because the default value current_time
is not valid for the type DATETIME
. That's what it says, and that's whats going on.
The only field you can use current_time
on is a timestamp.
Based on the very helpful answer by joran I was able to come up with this solution for a stable color scale for a boolean factor (TRUE
, FALSE
).
boolColors <- as.character(c("TRUE"="#5aae61", "FALSE"="#7b3294"))
boolScale <- scale_colour_manual(name="myboolean", values=boolColors)
ggplot(myDataFrame, aes(date, duration)) +
geom_point(aes(colour = myboolean)) +
boolScale
Since ColorBrewer isn't very helpful with binary color scales, the two needed colors are defined manually.
Here myboolean
is the name of the column in myDataFrame
holding the TRUE/FALSE factor. date
and duration
are the column names to be mapped to the x and y axis of the plot in this example.

I know this is old, but, in running into a vendor that inconsistently uses 5 different date formats in their APIs (and test servers with a variety of PHP versions from the 5's through the latest 7's), I decided to write a universal converter that works with a myriad of PHP versions.
This converter will take virtually any input, including any standard datetime format (including with or without milliseconds) and any Epoch Time representation (including with or without milliseconds) and convert it to virtually any other format.
To call it:
$TheDateTimeIWant=convertAnyDateTome_toMyDateTime([thedateIhave],[theformatIwant]);
Sending null for the format will make the function return the datetime in Epoch/Unix Time. Otherwise, send any format string that date() supports, as well as with ".u" for milliseconds (I handle milliseconds as well, even though date() returns zeros).
Here's the code:
<?php
function convertAnyDateTime_toMyDateTime($dttm,$dtFormat)
{
if (!isset($dttm))
{
return "";
}
$timepieces = array();
if (is_numeric($dttm))
{
$rettime=$dttm;
}
else
{
$rettime=strtotime($dttm);
if (strpos($dttm,".")>0 and strpos($dttm,"-",strpos($dttm,"."))>0)
{
$rettime=$rettime.substr($dttm,strpos($dttm,"."),strpos($dttm,"-",strpos($dttm,"."))-strpos($dttm,"."));
$timepieces[1]="";
}
else if (strpos($dttm,".")>0 and strpos($dttm,"-",strpos($dttm,"."))==0)
{
preg_match('/([0-9]+)([^0-9]+)/',substr($dttm,strpos($dttm,"."))." ",$timepieces);
$rettime=$rettime.".".$timepieces[1];
}
}
if (isset($dtFormat))
{
// RETURN as ANY date format sent
if (strpos($dtFormat,".u")>0) // Deal with milliseconds
{
$rettime=date($dtFormat,$rettime);
$rettime=substr($rettime,0,strripos($rettime,".")+1).$timepieces[1];
}
else // NO milliseconds wanted
{
$rettime=date($dtFormat,$rettime);
}
}
else
{
// RETURN Epoch Time (do nothing, we already built Epoch Time)
}
return $rettime;
}
?>
Here's some sample calls - you will note it also handles any time zone data (though as noted above, any non GMT time is returned in your time zone).

The only thing not in this version is the ability to select the time zone you want the returned datetime to be in. Originally, I wrote this to change any datetime to Epoch Time, so, I didn't need time zone support. It's trivial to add though.
This is expected.
Refer to Javadocs for split
.
Splits this string around matches of the given regular expression.
This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
You cannot expect to parse a date with a SimpleDateFormat that is set up with a different format.
To parse your "Thu Jun 18 20:56:02 EDT 2009" date string you need a SimpleDateFormat like this (roughly):
SimpleDateFormat parser=new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
Use this to parse the string into a Date, and then your other SimpleDateFormat to turn that Date into the format you want.
String input = "Thu Jun 18 20:56:02 EDT 2009";
SimpleDateFormat parser = new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
Date date = parser.parse(input);
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String formattedDate = formatter.format(date);

Since the Length
property of System.String
is an Int32
, I would guess that that the maximum length would be 2,147,483,647 chars (max Int32
size). If it allowed longer you couldn't check the Length since that would fail.
Responsive text alignment has been added in Bootstrap V4:
https://getbootstrap.com/docs/4.0/utilities/text/#text-alignment
For left, right, and center alignment, responsive classes are available that use the same viewport width breakpoints as the grid system.
<p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>
JSON.stringify
returns a String
. So, for example:
var data = [
{ id: 1, name: "bob" },
{ id: 2, name: "john" },
{ id: 3, name: "jake" },
];
JSON.stringify(data)
will return the equivalent of:
"[{\"id\":1,\"name\":\"bob\"},{\"id\":2,\"name\":\"john\"},{\"id\":3,\"name\":\"jake\"}]"
as a String
value.
So when you have
<% for(var i=0; i<JSON.stringify(data).length; i++) {%>
what that ends up looking like is:
<% for(var i=0; i<"[{\"id\":1,\"name\":\"bob\"},{\"id\":2,\"name\":\"john\"},{\"id\":3,\"name\":\"jake\"}]".length; i++) {%>
which is probably not what you want. What you probably do want is something like this:
<table>
<% for(var i=0; i < data.length; i++) { %>
<tr>
<td><%= data[i].id %></td>
<td><%= data[i].name %></td>
</tr>
<% } %>
</table>
This will output the following table (using the example data
from above):
<table>
<tr>
<td>1</td>
<td>bob</td>
</tr>
<tr>
<td>2</td>
<td>john</td>
</tr>
<tr>
<td>3</td>
<td>jake</td>
</tr>
</table>
Assuming you're currently on the branch you want to rename:
git branch -m newname
This is documented in the manual for git-branch
, which you can view using
man git-branch
or
git help branch
Specifically, the command is
git branch (-m | -M) [<oldbranch>] <newbranch>
where the parameters are:
<oldbranch>
The name of an existing branch to rename.
<newbranch>
The new name for an existing branch. The same restrictions as for <branchname> apply.
<oldbranch>
is optional, if you want to rename the current branch.
Json stands for JavaScript Object Notation really all json is are javascript objects so your array is in json form already. To write it out in a div you could do a bunch of things one of the easiest I think would be:
objectDiv.innerHTML = filter;
where objectDiv is the div you want selected from the DOM using jquery. If you wanted to list parts of the array out you could access them since it is a javascript object like so:
objectDiv.innerHTML = filter.dvals.valueToDisplay; //brand or count depending.
edit: anything you want to be a string but is not currently (which is rare javascript treats almost everything as a string) just use the toString()
function built in. so line above if you needed it would be filter.dvals.valueToDisplay.toString();
second edit to clarify: this answer is in response to the OP's comments and not completely to his original question.
