I received this same issue on SpringSource Tools ver 2.8.0.RELEASE. I had to do Maven -> Update Maven Dependencies and check the option for "Force Update of Snapshot/Releases".
While looking at the same problem, I found an example
<style type="text/css">
#topright {
position: absolute;
right: 0;
top: 0;
display: block;
height: 125px;
width: 125px;
background: url(TRbanner.gif) no-repeat;
text-indent: -999em;
text-decoration: none;
}
</style>
<a id="topright" href="#" title="TopRight">Top Right Link Text</a>
The trick here is to create a small, (I used GIMP) a PNG (or GIF) that has a transparent background, (and then just delete the opposite bottom corner.)
First, it's usually better to be explicit about your intent. So if you know the string ends in .rtf
, and you want to remove that .rtf
, you can just use var2=${var%.rtf}
. One potentially-useful aspect of this approach is that if the string doesn't end in .rtf
, it is not changed at all; var2
will contain an unmodified copy of var
.
If you want to remove a filename suffix but don't know or care exactly what it is, you can use var2=${var%.*}
to remove everything starting with the last .
. Or, if you only want to keep everything up to but not including the first .
, you can use var2=${var%%.*}
. Those options have the same result if there's only one .
, but if there might be more than one, you get to pick which end of the string to work from. On the other hand, if there's no .
in the string at all, var2
will again be an unchanged copy of var
.
If you really want to always remove a specific number of characters, here are some options.
You tagged this bash
specifically, so we'll start with bash builtins. The one which has worked the longest is the same suffix-removal syntax I used above: to remove four characters, use var2=${var%????}
. Or to remove four characters only if the first one is a dot, use var2=${var%.???}
, which is like var2=${var%.*}
but only removes the suffix if the part after the dot is exactly three characters. As you can see, to count characters this way, you need one question mark per unknown character removed, so this approach gets unwieldy for larger substring lengths.
An option in newer shell versions is substring extraction: var2=${var:0:${#var}-4}
. Here you can put any number in place of the 4
to remove a different number of characters. The ${#var}
is replaced by the length of the string, so this is actually asking to extract and keep (length - 4) characters starting with the first one (at index 0). With this approach, you lose the option to make the change only if the string matches a pattern; no matter what the actual value of the string is, the copy will include all but its last four characters.
Bash lets you leave the start index out; it defaults to 0, so you can shorten that to just var2=${var::${#var}-4}
. In fact, newer versions of bash (specifically 4+, which means the one that ships with MacOS won't work) recognize negative lengths as end indexes counting back from the end of the string, so you can get rid of the string-length expression, too: var2=${var::-4}
.
If you're not actually using bash but some other POSIX-type shell, the pattern-based suffix removal with %
will still work – even in plain old dash, where the index-based substring extraction won't. Ksh and zsh do both support substring extraction, but require the explicit 0 start index; zsh also supports the negative end index, while ksh requires the length expression. Note that zsh, which indexes arrays starting at 1, nonetheless indexes strings starting at 0 if you use this bash-compatible syntax; but you can also treat parameters as arrays of characters, in which case it uses a 1-based count and expects a start and inclusive end position in brackets: var2=$var[1,-5]
.
Instead of using built-in shell parameter expansion, you can of course run some utility program to modify the string and capture its output with command substitution. There are several commands that will work; one is var2=$(sed 's/.\{4\}$//' <<<"$var")
.
This question is confusing. A regular object, {}
doesn't have a length
property unless you're intending to make your own function constructor which generates custom objects which do have it ( in which case you didn't specify ).
Meaning, you have to get the "length" by a for..in
statement on the object, since length
is not set, and increment a counter.
I'm confused as to why you need the length
. Are you manually setting 0
on the object, or are you relying on custom string keys? eg obj['foo'] = 'bar';
. If the latter, again, why the need for length?
Edit #1: Why can't you just do this?
list = [ {name:'john'}, {name:'bob'} ];
Then iterate over list? The length
is already set.
JTextField
allows us to getText()
and setText()
these are used to get and set the contents of the text field, for example.
text = texfield.getText();
hope this helps
I like to create a boolean
and then use that in a logical if
.
//kick unvalidated users to the login page
var onLoginPage = (window.location.href.indexOf("login") > -1);
if (!onLoginPage) {
console.log('redirected to login page');
window.location = "/login";
} else {
console.log('already on the login page');
}
If you don't wish to use compact on close (eg, because the front-end mdb is a robot program that runs continually), and you don't want to create a separate mdb just for compacting, consider using a cmd file.
I let my robot.mdb check its own size:
FileLen(CurrentDb.Name))
If its size exceeds 1 GB, it creates a cmd file like this ...
Dim f As Integer
Dim Folder As String
Dim Access As String
'select Access in the correct PF directory (my robot.mdb runs in 32-bit MSAccess, on 32-bit and 64-bit machines)
If Dir("C:\Program Files (x86)\Microsoft Office\Office\MSACCESS.EXE") > "" Then
Access = """C:\Program Files (x86)\Microsoft Office\Office\MSACCESS.EXE"""
Else
Access = """C:\Program Files\Microsoft Office\Office\MSACCESS.EXE"""
End If
Folder = ExtractFileDir(CurrentDb.Name)
f = FreeFile
Open Folder & "comrep.cmd" For Output As f
'wait until robot.mdb closes (ldb file is gone), then compact robot.mdb
Print #f, ":checkldb1"
Print #f, "if exist " & Folder & "robot.ldb goto checkldb1"
Print #f, Access & " " & Folder & "robot.mdb /compact"
'wait until the robot mdb closes, then start it
Print #f, ":checkldb2"
Print #f, "if exist " & Folder & "robot.ldb goto checkldb2"
Print #f, Access & " " & Folder & "robot.mdb"
Close f
... launches the cmd file ...
Shell ExtractFileDir(CurrentDb.Name) & "comrep.cmd"
... and shuts down ...
DoCmd.Quit
Next, the cmd file compacts and restarts robot.mdb.
just use
file:///
works in IE, Firefox and Chrome as far as I can tell.

The documentation libraries phpdoc and Doxygen perform a kind of code analysis. Doxygen, for example, can be configured to render nice inheritance graphs with Graphviz.
Another option is xhprof, which is similar to Xdebug, but lighter, making it suitable for production servers. The tool includes a PHP-based interface.
it simple way in xml:
android:maxLength="@{length}"
for setting it programmatically you can use the following function
public static void setMaxLengthOfEditText(EditText editText, int length) {
InputFilter[] filters = editText.getFilters();
List arrayList = new ArrayList();
int i2 = 0;
if (filters != null && filters.length > 0) {
int filtersSize = filters.length;
int i3 = 0;
while (i2 < filtersSize) {
Object obj = filters[i2];
if (obj instanceof LengthFilter) {
arrayList.add(new LengthFilter(length));
i3 = 1;
} else {
arrayList.add(obj);
}
i2++;
}
i2 = i3;
}
if (i2 == 0) {
arrayList.add(new LengthFilter(length));
}
if (!arrayList.isEmpty()) {
editText.setFilters((InputFilter[]) arrayList.toArray(new InputFilter[arrayList.size()]));
}
}
If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json
Json(someDictionaryObj, JsonRequestBehavior.AllowGet);
Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5
as for your web request...it seems ok at first glance..
I would use something like this..
public void WebRequestinJson(string url, string postData)
{
StreamWriter requestWriter;
var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;
webRequest.ContentType = "application/json";
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
}
}
May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.
If you type this command:
echo cd d:/some/path >> ~/.bashrc
Appends the line cd d:/some/path
to .bashrc
. The >>
creates a file if it doesn’t exist and then appends.
Make sure if all the spring jar file's version in your build path and the version mentioned in the xml file are same.
south
plugin:Like T.T suggested in his answer, my previous answer was for south
migration plugin, when Django hasn't any schema migration features.
Now (works in Django 1.9+):
You can try this!
python manage.py makemigrations python manage.py migrate --run-syncdb
south
migrations pluginAs I can see you done it all in wrong order, to fix it up your should complete this checklist (I assume you can't delete sqlite3 database file to start over):
- Grab any SQLite GUI tool (i.e. http://sqliteadmin.orbmu2k.de/)
- Change your model definition to match database definition (best approach is to comment new fields)
- Delete
migrations
folder in your model- Delete rows in
south_migrationhistory
table whereapp_name
match your application name (probablyhomework
)- Invoke:
./manage.py schemamigration <app_name> --initial
- Create tables by
./manage.py migrate <app_name> --fake
(--fake
will skip SQL execute because table already exists in your database)- Make changes to your app's model
- Invoke
./manage.py schemamigration <app_name> --auto
- Then apply changes to database:
./manage.py migrate <app_name>
Steps 7,8,9 repeat whenever your model needs any changes.
<div style="cursor: pointer;" onclick="theFunction()">
is the simplest thing that works.
Of course in the final solution you should separate the markup from styling (css) and behavior (javascript) - read on it on a list apart for good practices on not just solving this particular problem but in markup design in general.
You're declaring a virtual
function and not defining it:
virtual void calculateCredits();
Either define it or declare it as:
virtual void calculateCredits() = 0;
Or simply:
virtual void calculateCredits() { };

According to the source code located here, starting at line 850, PostgreSQL doesn't explicitly limit the number of arguments.
The following is a code comment from line 870:
/*
* We try to generate a ScalarArrayOpExpr from IN/NOT IN, but this is only
* possible if the inputs are all scalars (no RowExprs) and there is a
* suitable array type available. If not, we fall back to a boolean
* condition tree with multiple copies of the lefthand expression.
* Also, any IN-list items that contain Vars are handled as separate
* boolean conditions, because that gives the planner more scope for
* optimization on such clauses.
*
* First step: transform all the inputs, and detect whether any are
* RowExprs or contain Vars.

I wound up writing my own command-line tool to take care of this. It's similar to cut
, except it knows what to do with quoted fields, etc. This tool, paired with @Jimothy's answer, allows me to get a headerless CSV from a remote MySQL server I have no filesystem access to onto my local machine with this command:
$ mysql -N -e "select people, places from things" | csvm -i '\t' -o ','

In addition to what has been said, prior to returning your error code, fire off an assert or similar diagnostic when an error is returned, as it will make tracing a lot easier. The way I do this is to have a customised assert that still gets compiled in at release but only gets fired when the software is in diagnostics mode, with an option to silently report to a log file or pause on screen.
I personally return error codes as negative integers with no_error as zero , but it does leave you with the possible following bug
if (MyFunc())
DoSomething();
An alternative is have a failure always returned as zero, and use a LastError() function to provide details of the actual error.
Try setting a property in each pom to find the main project directory.
In the parent:
<properties>
<main.basedir>${project.basedir}</main.basedir>
</properties>
In the children:
<properties>
<main.basedir>${project.parent.basedir}</main.basedir>
</properties>
In the grandchildren:
<properties>
<main.basedir>${project.parent.parent.basedir}</main.basedir>
</properties>
you can use ssl for your host there is free project for ssl like letsencrypt https://letsencrypt.org/
If you only need the dynamic properties for JSON serialization/deserialization, eg if your API accepts a JSON object with different fields depending on context, then you can use the JsonExtensionData
attribute available in Newtonsoft.Json or System.Text.Json.
Example:
public class Pet
{
public string Name { get; set; }
public string Type { get; set; }
[JsonExtensionData]
public IDictionary<string, object> AdditionalData { get; set; }
}
Then you can deserialize JSON:
public class Program
{
public static void Main()
{
var bingo = JsonConvert.DeserializeObject<Pet>("{\"Name\": \"Bingo\", \"Type\": \"Dog\", \"Legs\": 4 }");
Console.WriteLine(bingo.AdditionalData["Legs"]); // 4
var tweety = JsonConvert.DeserializeObject<Pet>("{\"Name\": \"Tweety Pie\", \"Type\": \"Bird\", \"CanFly\": true }");
Console.WriteLine(tweety.AdditionalData["CanFly"]); // True
tweety.AdditionalData["Color"] = "#ffff00";
Console.WriteLine(JsonConvert.SerializeObject(tweety)); // {"Name":"Tweety Pie","Type":"Bird","CanFly":true,"Color":"#ffff00"}
}
}
It sets the distance of the inset between the content view and the enclosing scroll view.
Obj-C
aScrollView.contentInset = UIEdgeInsetsMake(0, 0, 0, 7.0);
Swift 5.0
aScrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 7.0)
Here's a good iOS Reference Library article on scroll views that has an informative screenshot (fig 1-3) - I'll replicate it via text here:
_|?_cW_?_|_?_
| |
---------------
|content| ?
? |content| contentInset.top
cH |content|
? |content| contentInset.bottom
|content| ?
---------------
_|_______|___
?
(cH = contentSize.height; cW = contentSize.width)
The scroll view encloses the content view plus whatever padding is provided by the specified content insets.
Your other option would be to to add this to the end of your declaration:
where T : class
where T: IList
That way it will allow you to return null.
In the shell, you can't execute more than one statement at a time:
>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement
You need to execute them one by one:
>>> x = 5
>>> y = 6
>>>
When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

if (stripos($str,$arr_value) !== false) return true; //if $arr_value is found in $str return true
}
return false; //else return false
}
how to use
$owned_urls = array('website1.com', 'website2.com', 'website3.com');
//this example should return FOUND
$string = 'my domain name is website3.com';
if (array_in_string($string, $owned_urls)) {

}
else {
echo "second: Match not found<br>";

stripos function is not very strict. it's not case sensitive or it can match a part of a word http://php.net/manual/ro/function.stripos.php
if you want that search to be case sensitive use strpos http://php.net/manual/ro/function.strpos.php

I eventually tracked this down to the Anonymous Authentication Credentials. I don't know what had changed, because this application used to work, but anyway, this is what I did: Click on the Application -> Authentication. Make sure Anonymous Authentication is enabled (it was, in my case), but also click on Edit... and change the anonymous user identity to "Application pool identity" not "Specific user". Making this change worked for me.

Use ng-click
in place of onclick
. and its as simple as that:
<a href="www.mysite.com" ng-click="return theFunction();">Item</a>
<script type="text/javascript">
function theFunction () {
// return true or false, depending on whether you want to allow
// the`href` property to follow through or not
}
</script>
select method > right click > References > Workspace/Project (your preferred context )
or
(Ctrl+Shift+G)
This will show you a Search view containing the hierarchy of class and method which using this method.
If you want to want to treat 1,2 and 2,1 as the same pair, then this will give you the unique list on MS-SQL:

FROM pairs

I didn't find the suggestion to use UIButton
in the answers above. So I will try to prove that this is a good choice.
button.contentEdgeInsets = UIEdgeInsets(top: 0, left: 8, bottom: 0, right: 8)
In my situation using UIButton
was the best solution because:
UIView
as a container for UILabel
(i.e. I wanted to simplify math calculations for Autolayout in my cell)NSParagraphStyle
(because tailIndent
works incorrect with Autolayout – width of UILabel
is smaller than expected)UITextView
(because of possible side effects)UILabel
(less code fewer bugs)That's why using the contentEdgeInsets
from UIButton
in my situation became the easiest way to add text margins.
Hope this will help someone.
If you give your table a unique id, its easier:
<div id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a"
onmouseup="checkMultipleSelection(this,event);">
<table id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table"
cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td style="width:50px; text-align:left;">09:15 AM</td>
<td style="width:50px; text-align:left;">Item001</td>
<td style="width:50px; text-align:left;">10</td>
<td style="width:50px; text-align:left;">Address1</td>
<td style="width:50px; text-align:left;">46545465</td>
<td style="width:50px; text-align:left;">ref1</td>
</tr>
</table>
</div>
var multiselect =
document.getElementById(
'ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table'
).rows[0].cells,
timeXaddr = [multiselect[0].innerHTML, multiselect[2].innerHTML];
//=> timeXaddr now an array containing ['09:15 AM', 'Address1'];
Use ssh for that purpose. Generate keys without using a password and place it to .authorized_keys at the remote machine. Create the script to be run remotely, copy it to the other machine and then just run it remotely using ssh.
I used this approach many times with a big success. Also note that it is much more secure than telnet.
If the to-be-updated component is not inside the same NamingContainer

<p:ajax process="@this" update="count :subTotal"/>
To be sure, check the client ID of the subTotal
component in the generated HTML for the actual value. If it's inside for example a h:form
as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.
<p:ajax process="@this" update="count :formId:subTotal"/>
Space separation of IDs is more recommended as <f:ajax>
doesn't support comma separation and starters would otherwise get confused.
In case that you're interested in specific lines, use a result-array:
declare RESULT=($(./myscript)) # (..) = array
echo "First line: ${RESULT[0]}"
echo "Second line: ${RESULT[1]}"
echo "N-th line: ${RESULT[N]}"
Another alternative is to nest conditions
<ng-container *ngIf="foo === 1;else second"></ng-container>
<ng-template #second>
<ng-container *ngIf="foo === 2;else third"></ng-container>
</ng-template>
<ng-template #third></ng-template>
Use -I
in grep.
Example: grep SEARCH_ME -Irs ~/logs
.
Take a look at the java.text.MessageFormat
class, MessageFormat takes a set of objects, formats them, then inserts the formatted strings into the pattern at the appropriate places.
Object[] params = new Object[]{"hello", "!"};
String msg = MessageFormat.format("{0} world {1}", params);
Do not use floats to store fixed-point, accuracy-required data. This example shows how to convert a float to NVARCHAR(50) properly, while also showing why it is a bad idea to use floats for precision data.
create table #f ([Column_Name] float)
insert #f select 9072351234
insert #f select 907235123400000000000
select
cast([Column_Name] as nvarchar(50)),
--cast([Column_Name] as int), Arithmetic overflow
--cast([Column_Name] as bigint), Arithmetic overflow
CAST(LTRIM(STR([Column_Name],50)) AS NVARCHAR(50))
from #f
Output
9.07235e+009 9072351234
9.07235e+020 907235123400000010000
You may notice that the 2nd output ends with '10000' even though the data we tried to store in the table ends with '00000'. It is because float
datatype has a fixed number of significant figures supported, which doesn't extend that far.
I use this function datetime_to_local_timezone()
, which seems overly convoluted but I found no simpler version of a function that converts a datetime
instance to the local time zone, as configured in the operating system, with the UTC offset that was in effect at that time:
import time, datetime
def datetime_to_local_timezone(dt):
epoch = dt.timestamp() # Get POSIX timestamp of the specified datetime.
st_time = time.localtime(epoch) # Get struct_time for the timestamp. This will be created using the system's locale and it's time zone information.
tz = datetime.timezone(datetime.timedelta(seconds = st_time.tm_gmtoff)) # Create a timezone object with the computed offset in the struct_time.
return dt.astimezone(tz) # Move the datetime instance to the new time zone.
utc = datetime.timezone(datetime.timedelta())
dt1 = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, utc) # DST was in effect
dt2 = datetime.datetime(2009, 1, 10, 18, 44, 59, 193982, utc) # DST was not in effect
print(dt1)
print(datetime_to_local_timezone(dt1))
print(dt2)
print(datetime_to_local_timezone(dt2))
This example prints four dates. For two moments in time, one in January and one in July 2009, each, it prints the timestamp once in UTC and once in the local time zone. Here, where CET (UTC+01:00) is used in the winter and CEST (UTC+02:00) is used in the summer, it prints the following:
2009-07-10 18:44:59.193982+00:00
2009-07-10 20:44:59.193982+02:00
2009-01-10 18:44:59.193982+00:00
2009-01-10 19:44:59.193982+01:00

A generator is effectively a function that returns (data) before it is finished, but it pauses at that point, and you can resume the function at that point.
>>> def myGenerator():
... yield 'These'
... yield 'words'
... yield 'come'
... yield 'one'
... yield 'at'
... yield 'a'
... yield 'time'
>>> myGeneratorInstance = myGenerator()
>>> next(myGeneratorInstance)
These
>>> next(myGeneratorInstance)
words
and so on. The (or one) benefit of generators is that because they deal with data one piece at a time, you can deal with large amounts of data; with lists, excessive memory requirements could become a problem. Generators, just like lists, are iterable, so they can be used in the same ways:
>>> for word in myGeneratorInstance:
... print word
These
words
come
one
at
a
time
Note that generators provide another way to deal with infinity, for example
>>> from time import gmtime, strftime
>>> def myGen():
... while True:
... yield strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime())
>>> myGeneratorInstance = myGen()
>>> next(myGeneratorInstance)
Thu, 28 Jun 2001 14:17:15 +0000
>>> next(myGeneratorInstance)
Thu, 28 Jun 2001 14:18:02 +0000
The generator encapsulates an infinite loop, but this isn't a problem because you only get each answer every time you ask for it.

The trick is to use useradd
instead of its interactive wrapper adduser
.
I usually create users with:
RUN useradd -ms /bin/bash newuser
which creates a home directory for the user and ensures that bash is the default shell.
You can then add:
USER newuser
WORKDIR /home/newuser
to your dockerfile. Every command afterwards as well as interactive sessions will be executed as user newuser
:
docker run -t -i image
newuser@131b7ad86360:~$
You might have to give newuser
the permissions to execute the programs you intend to run before invoking the user command.
Using non-privileged users inside containers is a good idea for security reasons. It also has a few drawbacks. Most importantly, people deriving images from your image will have to switch back to root before they can execute commands with superuser privileges.
You need to do a while loop to get the result from the SQL query, like this:
require_once('db.php');
$sql="SELECT * FROM modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )
FROM modul1open) ORDER BY idM1O LIMIT 1";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
// If you want to display all results from the query at once:
print_r($row);
// If you want to display the results one by one
echo $row['column1'];
echo $row['column2']; // etc..
}
Also I would strongly recommend not using mysql_* since it's deprecated. Instead use the mysqli
or PDO
extension. You can read more about that here.
Why not try FROM_UNIXTIME(unix_timestamp, format)
?
In rails 4 you need to make the changes below:
config.assets.compile = true
config.assets.precompile = ['*.js', '*.css', '*.css.erb']
This works with me. use following command to pre-compile assets
RAILS_ENV=production bundle exec rake assets:precompile
Best of luck!
Here's a solution that doesn't require creating a function or listing all instances of characters to replace. It uses a recursive WITH statement in combination with a PATINDEX to find unwanted chars. It will replace all unwanted chars in a column - up to 100 unique bad characters contained in any given string. (E.G. "ABC123DEF234" would contain 4 bad characters 1, 2, 3 and 4) The 100 limit is the maximum number of recursions allowed in a WITH statement, but this doesn't impose a limit on the number of rows to process, which is only limited by the memory available.
If you don't want DISTINCT results, you can remove the two options from the code.
-- Create some test data:
SELECT * INTO #testData
FROM (VALUES ('ABC DEF,K.l(p)'),('123H,J,234'),('ABCD EFG')) as t(TXT)
-- Actual query:
-- Remove non-alpha chars: '%[^A-Z]%'
-- Remove non-alphanumeric chars: '%[^A-Z0-9]%'
DECLARE @BadCharacterPattern VARCHAR(250) = '%[^A-Z]%';
WITH recurMain as (
SELECT DISTINCT CAST(TXT AS VARCHAR(250)) AS TXT, PATINDEX(@BadCharacterPattern, TXT) AS BadCharIndex
FROM #testData
UNION ALL
SELECT CAST(TXT AS VARCHAR(250)) AS TXT, PATINDEX(@BadCharacterPattern, TXT) AS BadCharIndex
FROM (
SELECT
CASE WHEN BadCharIndex > 0
THEN REPLACE(TXT, SUBSTRING(TXT, BadCharIndex, 1), '')
ELSE TXT
END AS TXT
FROM recurMain
WHERE BadCharIndex > 0
) badCharFinder
)
SELECT DISTINCT TXT
FROM recurMain
WHERE BadCharIndex = 0;

Option 1- From Studio
In Android Studio, go to File > Project Structure. Then select the "project" tab on the left.
Your Gradle version will be displayed here.
Option 2- gradle-wrapper.properties
If you are using the Gradle wrapper, then your project will have a gradle/wrapper/gradle-wrapper.properties
folder.
This file should contain a line like this:
distributionUrl=https\://services.gradle.org/distributions/gradle-2.2.1-all.zip
This determines which version of Gradle you are using. In this case, gradle-2.2.1-all.zip
means I am using Gradle 2.2.1.
Option 3- Local Gradle distribution
If you are using a version of Gradle installed on your system instead of the wrapper, you can run gradle --version
to check.
write the below style into same html file head section or write into a .css file
<style type="text/css">
.submit input
{
color: #000;
background: #ffa20f;
border: 2px outset #d7b9c9
}
</style>
<input type="submit" class="submit"/>
.submit - in css . means class , so i created submit class with set of attributes
and applied that class to the submit tag, using class attribute

There is indeed no 64 bit version of Jet - and no plans (apparently) to produce one.
You might be able to use the ACE 64 bit driver: http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23734
However, you may be able to switch the project to 32bit in the Express version (I haven't tried and don't have 2008 installed in any flavour anymore)
Maybe it's time to scrap Access databases altogether, bite the bullet and go for SQL server instead?
This is an example for a RelativeLayout:
RelativeLayout relativeLayout=(RelativeLayout)vi.findViewById(R.id.RelativeLayoutLeft);
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
relativeLayout.setLayoutParams(params);
With another kind of layout (example LinearLayout) you just simply has to change RelativeLayout for LinearLayout.
Building on Jeremy Bader and David West's excellent answers, a Swift 3 extension:
extension String {
func withBoldText(boldPartsOfString: Array<NSString>, font: UIFont!, boldFont: UIFont!) -> NSAttributedString {
let nonBoldFontAttribute = [NSFontAttributeName:font!]
let boldFontAttribute = [NSFontAttributeName:boldFont!]
let boldString = NSMutableAttributedString(string: self as String, attributes:nonBoldFontAttribute)
for i in 0 ..< boldPartsOfString.count {
boldString.addAttributes(boldFontAttribute, range: (self as NSString).range(of: boldPartsOfString[i] as String))
}
return boldString
}
}
Usage:
let label = UILabel()
let font = UIFont(name: "AvenirNext-Italic", size: 24)!
let boldFont = UIFont(name: "AvenirNext-BoldItalic", size: 24)!
label.attributedText = "Make sure your face is\nbrightly and evenly lit".withBoldText(
boldPartsOfString: ["brightly", "evenly"], font: font, boldFont: boldFont)
void NumericTextBoxInput(object sender, TextCompositionEventArgs e)
{
TextBox txt = (TextBox)sender;
var regex = new Regex(@"^[0-9]*(?:\.[0-9]{0,1})?$");
string str = txt.Text + e.Text.ToString();
int cntPrc = 0;
if (str.Contains('.'))
{
string[] tokens = str.Split('.');
if (tokens.Count() > 0)
{
string result = tokens[1];
char[] prc = result.ToCharArray();
cntPrc = prc.Count();
}
}
if (regex.IsMatch(e.Text) && !(e.Text == "." && ((TextBox)sender).Text.Contains(e.Text)) && (cntPrc < 3))
{
e.Handled = false;
}
else
{
e.Handled = true;
}
}
If you want to test the index to see if it works, here is the syntax:
SELECT *
FROM Table WITH(INDEX(Index_Name))
The WITH statement will force the index to be used.
You need to make sure and have the following:
#include <windows.h>
and not this:
#include "windows.h"
If that's not the problem, then check RichieHindle's response.

You will not be able to find out the password he chose. However, you may create a new user or set a new password to the existing user.
Usually, you can login as the postgres user:
Open a Terminal and do sudo su postgres
.
Now, after entering your admin password, you are able to launch psql
and do
CREATE USER yourname WITH SUPERUSER PASSWORD 'yourpassword';
This creates a new admin user. If you want to list the existing users, you could also do
\du
to list all users and then
ALTER USER yourusername WITH PASSWORD 'yournewpass';
Interfaces are not part of the ES6 but classes are.
If you really need them, you should look at TypeScript which support them.

I had the same error. It turns out that the cause was that the back end method was expecting different json data. In my Ajax call i had something like this:
$.ajax({
async: false,
type: "POST",
url: "http://13.82.13.196/api.aspx/PostAjax",
data: '{"url":"test"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
});
Now in my WebMethod, inside my C# backend code i had declared my endpoint like this:
public static string PostAjax(AjaxSettings settings)
Where AjaxSettings was declared:
public class AjaxSettings
{
public string url { get; set; }
}
The problem then was that the mapping between my ajax call and my back-end endpoint was not the same. As soon as i changed my ajax call to the following, it all worked well!
var data ='{"url":"test"}';
$.ajax({
async: false,
type: "POST",
url: "http://13.82.13.196/api.aspx/PostAjax",
data: '{"settings":'+data+'}',
contentType: "application/json; charset=utf-8",
dataType: "json"
});
I had to change the data variable inside the Ajax call in order to match the method signature exactly.
Can be done via slicing too
package main
import "fmt"
func main() {

NOTE: This solution only works for ASCII characters.
There are a couple of options there. The sample code is in Java, but a port to other languages should be straightforward.
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = (WebElement) ((JavascriptExecutor) driver).executeScript(
"return arguments[0].parentNode;", myElement);
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = myElement.findElement(By.xpath("./.."));
WebElement
Note: As you can see, for the JavaScript version you'll need the driver
. If you don't have direct access to it, you can retrieve it from the WebElement
using:
WebDriver driver = ((WrapsDriver) myElement).getWrappedDriver();
Make another div and add both 'dummy' and 'img-container' inside the div
Do HTML and CSS like follows
html , body {height:100%;}_x000D_
.responsive-container { height:100%; display:table; text-align:center; width:100%;}_x000D_
.inner-container {display:table-cell; vertical-align:middle;}
_x000D_
<div class="responsive-container">_x000D_
<div class="inner-container">_x000D_
<div class="dummy">Sample</div>_x000D_
<div class="img-container">_x000D_
Image tag_x000D_
</div>_x000D_
</div> _x000D_
</div>
_x000D_
Instead of 100% for the 'responsive-container' you can give the height that you want.,

The answers are missing a specific time of day timer here is on the next hour:
NSCalendarUnit allUnits = NSCalendarUnitYear | NSCalendarUnitMonth |
NSCalendarUnitDay | NSCalendarUnitHour |
NSCalendarUnitMinute | NSCalendarUnitSecond;
NSCalendar *calendar = [[ NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *weekdayComponents = [calendar components: allUnits
fromDate: [ NSDate date ] ];
[ weekdayComponents setHour: weekdayComponents.hour + 1 ];
[ weekdayComponents setMinute: 0 ];
[ weekdayComponents setSecond: 0 ];
NSDate *nextTime = [ calendar dateFromComponents: weekdayComponents ];
refreshTimer = [[ NSTimer alloc ] initWithFireDate: nextTime
interval: 0.0
target: self
selector: @selector( doRefresh )
userInfo: nil repeats: NO ];
[[NSRunLoop currentRunLoop] addTimer: refreshTimer forMode: NSDefaultRunLoopMode];
Of course, substitute "doRefresh" with your class's desired method
try to create the calendar object once and make the allUnits a static for efficiency.
adding one to hour component works just fine, no need for a midnight test (link)

An excellent 2014 IBM research paper “An Updated Performance Comparison of Virtual Machines and Linux Containers” by Felter et al. provides a comparison between bare metal, KVM, and Docker containers. The general result is: Docker is nearly identical to native performance and faster than KVM in every category.
The exception to this is Docker’s NAT — if you use port mapping (e.g., docker run -p 8080:8080
), then you can expect a minor hit in latency, as shown below. However, you can now use the host network stack (e.g., docker run --net=host
) when launching a Docker container, which will perform identically to the Native column (as shown in the Redis latency results lower down).
They also ran latency tests on a few specific services, such as Redis. You can see that above 20 client threads, highest latency overhead goes Docker NAT, then KVM, then a rough tie between Docker host/native.
Just because it’s a really useful paper, here are some other figures. Please download it for full access.

Now looking at CPU overhead:
Now some examples of memory (read the paper for details, memory can be extra tricky):

What does const
mean
First, realize that the semantics of a "const" keyword means different things to different people:
final
semantics - reference variable itself cannot be reassigned to point to another instance (memory location), but the instance itself is modifiableconst
pointer/reference semantics - means this reference cannot be used to modify the instance (e.g. cannot assign to instance variables, cannot invoke mutable methods) - affects the reference variable only, so a non-const reference pointing to the same instance could modify the instanceWhy or Why Not const
Second, if you really want to dig into some of the "pro" vs "con" arguments, see the discussion under this request for enhancement (RFE) "bug". This RFE requests a "readable-only reference"-type "const" feature. Opened in 1999 and then closed/rejected by Sun in 2005, the "const" topic was vigorously debated:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4211070
While there are a lot of good arguments on both sides, some of the oft-cited (but not necessarily compelling or clear-cut) reasons against const
include:
const
mean above)Before anyone tries to debate me about whether these are good or bad reasons, note that these are not my reasons. They are simply the "gist" of some of the reasons I gleaned from skimming the RFE discussion. I don't necessarily agree with them myself - I'm simply trying to cite why some people (not me) may feel a const
keyword may not be a good idea. Personally, I'd love more "const" semantics to be introduced to the language in an unambiguous manner.
If you need to have the number of unique values as an additional column in the data frame containing your values (a column which may represent sample size for example), plyr provides a neat way:
data_frame <- data.frame(v = rep(c(1,2, 2, 2), 25))
library("plyr")
data_frame <- ddply(data_frame, .(v), transform, n = length(v))
An alternative way is to use DateTime.DaysInMonth
to get the number of days in the current month as suggested by @Jade
Since we know the first day of the month will always 1
we can use it as default for the first day with the current Month & year as current.year,current.Month,1
.
var now = DateTime.Now; // get the current DateTime
//Get the number of days in the current month
int daysInMonth = DateTime.DaysInMonth (now.Year, now.Month);
//First day of the month is always 1
var firstDay = new DateTime(now.Year,now.Month,1);
//Last day will be similar to the number of days calculated above
var lastDay = new DateTime(now.Year,now.Month,daysInMonth);
//So
rdpStartDate.SelectedDate = firstDay;
rdpEndDate.SelectedDate = lastDay;
A very simple way to provide default values to your params: params[:foo] ||= 'default value'
Do I need to double the size of the .box div to 400px by 400px to match the new high res background image
No, but you do need to set the background-size
property to match the original dimensions:
@media (-webkit-min-device-pixel-ratio: 2),
(min-resolution: 192dpi) {
.box{
background:url('images/[email protected]') no-repeat top left;
background-size: 200px 200px;
}
}
EDIT
To add a little more to this answer, here is the retina detection query I tend to use:
@media
only screen and (-webkit-min-device-pixel-ratio: 2),
only screen and ( min--moz-device-pixel-ratio: 2),
only screen and ( -o-min-device-pixel-ratio: 2/1),
only screen and ( min-device-pixel-ratio: 2),
only screen and ( min-resolution: 192dpi),
only screen and ( min-resolution: 2dppx) {
}
NB. This min--moz-device-pixel-ratio:
is not a typo. It is a well documented bug in certain versions of Firefox and should be written like this in order to support older versions (prior to Firefox 16).
- Source
As @LiamNewmarch mentioned in the comments below, you can include the background-size
in your shorthand background

or whatever you are using and start coding.PMost likely because Notification Center is a relatively new feature, Apple didn't necessarily want to push a whole new paradigm for clearing notifications. So instead, they multi-purposed [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
to clear said notifications. It might seem a bit weird, and Apple might provide a more intuitive way to do this in the future, but for the time being it's the official way.
Myself, I use this snippet:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
which never fails to clear all of the app's notifications from Notification Center.

This creates a "jump" due to variable heights... to solve that, try something like this: Select the tallest image of a list
Or use media-query to set your own fixed height.
I agree with previous comment that might be best to consider a different approach. My suggest would be write a console application and use the windows scheduler:
This will:
I've written some code that provides "LINQ to HTML" functionality. I thought I would share it here. It is based on Majestic 12. It takes the Majestic-12 results and produces LINQ XML elements. At that point you can use all your LINQ to XML tools against the HTML. As an example:
IEnumerable<XNode> auctionNodes = Majestic12ToXml.Majestic12ToXml.ConvertNodesToXml(byteArrayOfAuctionHtml);
foreach (XElement anchorTag in auctionNodes.OfType<XElement>().DescendantsAndSelf("a")) {
if (anchorTag.Attribute("href") == null)
continue;
Console.WriteLine(anchorTag.Attribute("href").Value);
}
I wanted to use Majestic-12 because I know it has a lot of built-in knowledge with regards to HTML that is found in the wild. What I've found though is that to map the Majestic-12 results to something that LINQ will accept as XML requires additional work. The code I'm including does a lot of this cleansing, but as you use this you will find pages that are rejected. You'll need to fix up the code to address that. When an exception is thrown, check exception.Data["source"] as it is likely set to the HTML tag that caused the exception. Handling the HTML in a nice manner is at times not trivial...
So now that expectations are realistically low, here's the code :)

Following answer can help in this and other similar situations like synchronous AJAX call -
Working example
waitForMe().then(function(intentsArr){
console.log('Finally, I can execute!!!');
},
function(err){
console.log('This is error message.');
})
function waitForMe(){
// Returns promise
console.log('Inside waitForMe');
return new Promise(function(resolve, reject){
if(true){ // Try changing to 'false'
setTimeout(function(){
console.log('waitForMe\'s function succeeded');
resolve();
}, 2500);
}
else{
setTimeout(function(){
console.log('waitForMe\'s else block failed');
resolve();
}, 2500);
}
});
}
Also check if the resource-name contains any illegal characters (for me it was a "-" in my-image)
Perhaps you can try adding this in your imports:
import 'rxjs/add/operator/catch';
You can also do:
return this.http.request(request)
.map(res => res.json())
.subscribe(
data => console.log(data),
err => console.log(err),
() => console.log('yay')
);
Per comments:
EXCEPTION: TypeError: Observable_1.Observable.throw is not a function
Similarly, for that, you can use:
import 'rxjs/add/observable/throw';
If it's really important that you have the correct date and time; it's best to have a service on your server (which you of course have running in UTC) that returns the time. You can then create a new Date on the client and compare the values and if necessary adjust all dates with the offset from the server time.
Why do this? I've had bug reports that was hard to reproduce because I could not find the error messages in the server log, until I noticed that the bug report was mailed two days after I'd received it. You can probably trust the browser to correctly handle time-zone conversion when being sent a UTC timestamp, but you obviously cannot trust the users to have their system clock correctly set. (If the users have their timezone incorrectly set too, there is not really any solution; other than printing the current server time in "local" time)
A simple way of "binarize" an image is to compare to a threshold: For example you can compare all elements in a matrix against a value with opencv in c++
cv::Mat img = cv::imread("image.jpg", CV_LOAD_IMAGE_GRAYSCALE);
cv::Mat bw = img > 128;
In this way, all pixels in the matrix greater than 128 now are white, and these less than 128 or equals will be black
Optionally, and for me gave good results is to apply blur
cv::blur( bw, bw, cv::Size(3,3) );
Later you can save it as said before with:
cv::imwrite("image_bw.jpg", bw);
Having the .htaccess file on the root folder, add this line. Make sure to delete all other useless rules you tried before:

Or try:

You use 'git pull' to keep your branches separate. I will use the actual repository and branch names to help since 'lbranch' and 'rbranch' are tough to decipher.
Let's use:
You, or any colleague, can run this to pull only your branch, no matter how many branches there are:
git init
git pull [email protected]:myteam/tlc daves_branch:refs/remotes/origin/daves_branch
Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin
not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors
at your server side.
You can fetch request using mode: 'cors'
. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.
So in both condition you need to configure cors
in your server or you need to use custom proxy server.
As an ArrayList
that line would be
import java.util.ArrayList;
...
ArrayList<Card> hand = new ArrayList<Card>();
To use the ArrayList
you have do
hand.get(i); //gets the element at position i
hand.add(obj); //adds the obj to the end of the list
hand.remove(i); //removes the element at position i
hand.add(i, obj); //adds the obj at the specified index
hand.set(i, obj); //overwrites the object at i with the new obj

Using OpenSSL's EVP interface (the following is for OpenSSL 1.1):
#include <iomanip>
#include <iostream>
#include <sstream>
#include <string>
#include <openssl/evp.h>
bool computeHash(const std::string& unhashed, std::string& hashed)
{
bool success = false;
EVP_MD_CTX* context = EVP_MD_CTX_new();
if(context != NULL)
{
if(EVP_DigestInit_ex(context, EVP_sha256(), NULL))
{
if(EVP_DigestUpdate(context, unhashed.c_str(), unhashed.length()))
{
unsigned char hash[EVP_MAX_MD_SIZE];
unsigned int lengthOfHash = 0;
if(EVP_DigestFinal_ex(context, hash, &lengthOfHash))
{
std::stringstream ss;
for(unsigned int i = 0; i < lengthOfHash; ++i)
{
ss << std::hex << std::setw(2) << std::setfill('0') << (int)hash[i];
}
hashed = ss.str();
success = true;
}
}
}
EVP_MD_CTX_free(context);
}
return success;
}
int main(int, char**)
{
std::string pw1 = "password1", pw1hashed;
std::string pw2 = "password2", pw2hashed;
std::string pw3 = "password3", pw3hashed;
std::string pw4 = "password4", pw4hashed;
hashPassword(pw1, pw1hashed);
hashPassword(pw2, pw2hashed);
hashPassword(pw3, pw3hashed);
hashPassword(pw4, pw4hashed);
std::cout << pw1hashed << std::endl;
std::cout << pw2hashed << std::endl;
std::cout << pw3hashed << std::endl;
std::cout << pw4hashed << std::endl;
return 0;
}
The advantage of this higher level interface is that you simply need to swap out the EVP_sha256()
call with another digest's function, e.g. EVP_sha512()
, to use a different digest. So it adds some flexibility.

I ended up with a combination of Roberts and chirags answers:
((EditText)findViewById(R.id.search_field)).setOnEditorActionListener(
new EditText.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// Identifier of the action. This will be either the identifier you supplied,
// or EditorInfo.IME_NULL if being called due to the enter key being pressed.
if (actionId == EditorInfo.IME_ACTION_SEARCH
|| actionId == EditorInfo.IME_ACTION_DONE
|| event.getAction() == KeyEvent.ACTION_DOWN
&& event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
onSearchAction(v);
return true;
}
// Return true if you have consumed the action, else false.
return false;
}
});
Update: The above code would some times activate the callback twice. Instead I've opted for the following code, which I got from the Google chat clients:
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// If triggered by an enter key, this is the event; otherwise, this is null.
if (event != null) {
// if shift key is down, then we want to insert the '\n' char in the TextView;
// otherwise, the default action is to send the message.
if (!event.isShiftPressed()) {
if (isPreparedForSending()) {
confirmSendMessageIfNeeded();
}
return true;
}
return false;
}
if (isPreparedForSending()) {
confirmSendMessageIfNeeded();
}
return true;

You can do a serialization-based deep clone using org.apache.commons.lang3.SerializationUtils.clone(T)
in Apache Commons Lang, but be careful—the performance is abysmal.
In general, it is best practice to write your own clone methods for each class of an object in the object graph needing cloning.
Eclipse by default does not know about your external Maven installation and uses the embedded one. Therefore in order for Eclipse to use your global settings you need to set it in menu Settings ? Maven ? Installations.

In your current window xaml.cs
file, call the below code:

Built-in toLocaleDateString()
does the job, but it will remove the leading 0s for the day and month, so we will get something like "1/9/1970", which is not perfect in my opinion. To get a proper format MM/DD/YYYY
we can use something like:
new Date(dateString).toLocaleDateString('en-US', {
day: '2-digit',
month: '2-digit',
year: 'numeric',
})
I don't believe there is a direct supported way. However, if you are desparate, then under navigation options, select to show system objects. Then in your table list, system tables will appear. Two tables are of interest here: MSysIMEXspecs and MSysIMEXColumns. You'll be able edit import and export information. Good luck!
I faced difficulties using "window.URL" with Opera Browser as it would result to "undefined". Also, with window.URL, the PDF document never opened in Internet Explorer and Microsoft Edge (it would remain waiting forever). I came up with the following solution that works in IE, Edge, Firefox, Chrome and Opera (have not tested with Safari):
$http.post(postUrl, data, {responseType: 'arraybuffer'})
.success(success).error(failed);
function success(data) {
openPDF(data.data, "myPDFdoc.pdf");
};
function failed(error) {...};
function openPDF(resData, fileName) {
var ieEDGE = navigator.userAgent.match(/Edge/g);
var ie = navigator.userAgent.match(/.NET/g); // IE 11+
var oldIE = navigator.userAgent.match(/MSIE/g);
var blob = new window.Blob([resData], { type: 'application/pdf' });
if (ie || oldIE || ieEDGE) {
window.navigator.msSaveBlob(blob, fileName);
}
else {
var reader = new window.FileReader();
reader.onloadend = function () {
window.location.href = reader.result;
};
reader.readAsDataURL(blob);
}
}
Let me know if it helped! :)
If you have still problems, try deactivating ("Clear") SOCKS
see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=281384 "I believe the reason for this is because it uses the SOCKS proxy instead of the HTTP proxy if SOCKS is configured."
Seems based on benchmarks at JSPerf that using +=
is the fastest method, though not necessarily in every browser.
For building strings in the DOM, it seems to be better to concatenate the string first and then add to the DOM, rather then iteratively add it to the dom. You should benchmark your own case though.

A tab is a tab. How many spaces it consumes is a display issue, and depends on the settings of your shell.
If you want to control the width of your data, then you could use the width
sub-specifiers in the printf
format string. Eg. :
printf("%5d", 2);
It's not a complete solution (if the value is longer than 5 characters, it will not be truncated), but might be ok for your needs.
If you want complete control, you'll probably have to implement it yourself.
Your code looks correct. Try logging in through your browser and if you are able to access your account come back and try your code again. Just make sure that you have typed your username and password correct

It also can be done using CSS and without tables or floats or fixed lengths by changing the content direction to rtl
and then back to ltr
, but the labels must go after each input.
To avoid this markup reordering, just set the label's text in a data-*
attribute and show it using an ::after
pseudo-element. I think it becomes much clearer.
Here is an example setting the label's text in a custom attribute called data-text
and showing them using the ::after
pseudo-element, so we don't mess with markup while changing direction
to rtl
and ltr
:
form
{
display: inline-block;
background-color: gold;
padding: 6px;
}
label{
display: block;
direction: rtl;
}
input{
direction: ltr;
}
label::after{
content: attr(data-text);
}
_x000D_
<form>
<label data-text="First Name">
<input type="text" />
</label>
<label data-text="Last Name">
<input type="text" />
</label>
<label data-text="E-mail">
<input type="text" />
</label>
</form>

You have to be careful while changing factors to numeric. Here is a line of code that would change a set of columns from factor to numeric. I am assuming here that the columns to be changed to numeric are 1, 3, 4 and 5 respectively. You could change it accordingly
cols = c(1, 3, 4, 5);
df[,cols] = apply(df[,cols], 2, function(x) as.numeric(as.character(x)));
Before you run a select query, run this:
SET SERVEROUT ON SIZE 6000
SELECT XMLAGG(XMLELEMENT(E,SUPLR_SUPLR_ID||',')).EXTRACT('//text()') "SUPPLIER"
FROM SUPPLIERS;
Read about request objects that your views receive: https://docs.djangoproject.com/en/dev/ref/request-response/#httprequest-objects
Also your hidden field needs a reliable name and then a value:
<input type="hidden" name="title" value="{{ source.title }}">
Then in a view:
request.POST.get("title", "")
I found that the first solution in the accepted answer to be problematic for cases where the newline character is still required. The easiest solution to the problem was doing this:
numpy.savetxt(filename, [a], delimiter='\t')
What does your text file look like?? Each line a record?
You'll have to check out the BULK INSERT statement - that should look something like:
BULK INSERT dbo.YourTableName
FROM 'D:\directory\YourFileName.csv'
WITH
(
CODEPAGE = '1252',
FIELDTERMINATOR = ';',
CHECK_CONSTRAINTS
)
Here, in my case, I'm importing a CSV file - but you should be able to import a text file just as well.
From the MSDN docs - here's a sample that hopefully works for a text file with one field per row:
BULK INSERT dbo.temp
FROM 'c:\temp\file.txt'
WITH
(
ROWTERMINATOR ='\n'
)
Seems to work just fine in my test environment :-)
I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.
If your request is XML Request use XML(text/xml).
If your request is JSON Request use JSON(application/json)
I know what you're trying to do, but why not simply do this:
$('div').addClass('hover');
The class is already defined in your CSS...
As for you original question, this has been asked before and it is not possible unfortunately. e.g. http://forum.jquery.com/topic/jquery-triggering-css-pseudo-selectors-like-hover
However, your desired functionality may be possible if your Stylesheet is defined in Javascript. see: http://www.4pmp.com/2009/11/dynamic-css-pseudo-class-styles-with-jquery/
Hope this helps!

I'd use RestSharp - https://github.com/restsharp/RestSharp
Create class to deserialize to:
public class MyObject {
public string Id { get; set; }
public string Text { get; set; }
...
}
And the code to get that object:
RestClient client = new RestClient("http://whatever.com");
RestRequest request = new RestRequest("path/to/object");
request.AddParameter("id", "123");
// The above code will make a request URL of
// "http://whatever.com/path/to/object?id=123"
// You can pick and choose what you need
var response = client.Execute<MyObject>(request);
MyObject obj = response.Data;
Check out http://restsharp.org/ to get started.
LocalDateTime.parse(
"2016-01-23 12:34".replace( " " , "T" )
)
.atZone( ZoneId.of( "Asia/Karachi" ) )
.plusMinutes( 10 )
Use the excellent java.time classes for date-time work. These classes supplant the troublesome old date-time classes such as java.util.Date
and java.util.Calendar
.
The java.time classes use standard ISO 8601 formats by default for parsing/generating strings of date-time values. To make your input string comply, replace the SPACE in the middle with a T
.
String input = "2016-01-23 12:34" ;
String inputModified = input.replace( " " , "T" );
LocalDateTime
Parse your input string as a LocalDateTime
as it lacks any info about time zone or offset-from-UTC.
LocalDateTime ldt = LocalDateTime.parse( inputModified );
Add ten minutes.
LocalDateTime ldtLater = ldt.plusMinutes( 10 );
ldt.toString(): 2016-01-23T12:34
ldtLater.toString(): 2016-01-23T12:44
That LocalDateTime
has no time zone, so it does not represent a point on the timeline. Apply a time zone to translate to an actual moment. Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
, or Asia/Karachi
. Never use the 3-4 letter abbreviation such as EST
or IST
or PKT
as they are not true time zones, not standardized, and not even unique(!).
ZonedDateTime
If you know the intended time zone for this value, apply a ZoneId
to get a ZonedDateTime
.
ZoneId z = ZoneId.of( "Asia/Karachi" );
ZonedDateTime zdt = ldt.atZone( z );
zdt.toString(): 2016-01-23T12:44+05:00[Asia/Karachi]
Think about whether to add those ten minutes before or after adding a time zone. You may get a very different result because of anomalies such as Daylight Saving Time (DST) that shift the wall-clock time.
Whether you should add the 10 minutes before or after adding the zone depends on the meaning of your business scenario and rules.
Tip: When you intend a specific moment on the timeline, always keep the time zone information. Do not lose that info, as done with your input data. Is the value 12:34
meant to be noon in Pakistan or noon in France or noon in Québec? If you meant noon in Pakistan, say so by including at least the offset-from-UTC (+05:00
), and better still, the name of the time zone (Asia/Karachi
).
Instant
If you want the same moment as seen through the lens of UTC, extract an Instant
. The Instant
class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).
Instant instant = zdt.toInstant();
Avoid the troublesome old date-time classes whenever possible. But if you must, you can convert. Call new methods added to the old classes.
java.util.Date utilDate = java.util.Date.from( instant );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to java.time.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
Edit: Now compatible with MSVC, C++ and non-GNU compilers (see end).
The question was "most efficient way." The OP doesn't specify platform, he could be compiling for a RISC based ATMEL chip with 256 bytes of flash storage for his code.
For the record, and for those (like me), who appreciate the difference between "the easiest way" and the "most efficient way", and who enjoy learning...

It requires no external libraries, and it should be blindingly fast. It handles uppercase, lowercase, invalid characters, odd-sized hex input (eg: 0xfff), and the maximum size is limited only by the compiler.
For non-GCC or C++ compilers or compilers that will not accept the fancy hextable declaration.
Replace the first statement with this (longer, but more conforming) version:

I'm not expert enough in the inner workings of Postgres to know why your query with the double condition in the WHERE
clause be not working. But one way to get around this would be to use a UNION
of the two queries which you know do work:
SELECT * FROM table_name WHERE boolean_column IS NULL
UNION
SELECT * FROM table_name WHERE boolean_column = FALSE
You could also try using COALESCE
:
SELECT * FROM table_name WHERE COALESCE(boolean_column, FALSE) = FALSE
This second query will replace all NULL
values with FALSE
and then compare against FALSE
in the WHERE
condition.
You can do something like that in ES6.
new Array(10).fill().map((e,i) => {
return {idx: i}
});
Do you want iteration? itertools.combinations. Common usage:
>>> import itertools
>>> itertools.combinations('abcd',2)
<itertools.combinations object at 0x01348F30>
>>> list(itertools.combinations('abcd',2))
[('a', 'b'), ('a', 'c'), ('a', 'd'), ('b', 'c'), ('b', 'd'), ('c', 'd')]
>>> [''.join(x) for x in itertools.combinations('abcd',2)]
['ab', 'ac', 'ad', 'bc', 'bd', 'cd']
If you just need to compute the formula, use math.factorial:
import math
def nCr(n,r):
f = math.factorial
return f(n) / f(r) / f(n-r)
if __name__ == '__main__':
print nCr(4,2)
In Python 3, use the integer division //
instead of /
to avoid overflows:
return f(n) // f(r) // f(n-r)

Maybe you can run this regex first to see if the line is all caps:
^[A-Z \d\W]+$
That will match only if it's a line like THING P1 MUST CONNECT TO X2.
Otherwise, you should be able to pull out the individual uppercase phrases with this:
[A-Z][A-Z\d]+
That should match "P1" and "J236" in The thing P1 must connect to the J236 thing in the Foo position.
This works well for me. It uses an array so you aren't looping through each cell. Runs much faster over large worksheet sections.

This is something of a generic solution:
<div class="outer">
<div class="inner">
Some content...
</div>
</div>
<style>
.outer {
overflow: hidden;
}
.inner {
margin-right: -16px;
overflow-y: scroll;
overflow-x: hidden;
}
</style>
The scroll bar is hidden by the parent div.
This requires you to use overflow:hidden in the parent div.
to convert to lower case is equivalent to rise bit 0x60 if you restrict yourself to ASCII:
for(char *p = pstr; *p; ++p)
*p = *p > 0x40 && *p < 0x5b ? *p | 0x60 : *p;
Here's my favorite bit arithmetic macro, which works for any type of unsigned integer array from unsigned char
up to size_t
(which is the biggest type that should be efficient to work with):
#define BITOP(a,b,op) \
((a)[(size_t)(b)/(8*sizeof *(a))] op ((size_t)1<<((size_t)(b)%(8*sizeof *(a)))))
To set a bit:
BITOP(array, bit, |=);
To clear a bit:
BITOP(array, bit, &=~);
To toggle a bit:
BITOP(array, bit, ^=);
To test a bit:
if (BITOP(array, bit, &)) ...
etc.
Folks above hit the right notes for storage, though if you also need to consider any PII data that needs to be stored then you can also stash into the keychain using something like https://github.com/oblador/react-native-keychain since ASyncStorage is unencrypted. It can be applied as part of the persist configuration in something like redux-persist.
Which operating system?
For windows machines, if you're writing a server to scale well, and therefore using I/O Completion Ports and async I/O, then the main limitation is the amount of non-paged pool that you're using for each active connection. This translates directly into a limit based on the amount of memory that your machine has installed (non-paged pool is a finite, fixed size amount that is based on the total memory installed).
For connections that don't see much traffic you can reduce make them more efficient by posting 'zero byte reads' which don't use non-paged pool and don't affect the locked pages limit (another potentially limited resource that may prevent you having lots of socket connections open).
Apart from that, well, you will need to profile but I've managed to get more than 70,000 concurrent connections on a modestly specified (760MB memory) server; see here http://www.lenholgate.com/blog/2005/11/windows-tcpip-server-performance.html for more details.
Obviously if you're using a less efficient architecture such as 'thread per connection' or 'select' then you should expect to achieve less impressive figures; but, IMHO, there's simply no reason to select such architectures for windows socket servers.
Edit: see here http://blogs.technet.com/markrussinovich/archive/2009/03/26/3211216.aspx; the way that the amount of non-paged pool is calculated has changed in Vista and Server 2008 and there's now much more available.
If you're using Hive 11 or better you can use the INSERT
statement with the LOCAL
keyword.
Example:
insert overwrite local directory '/home/carter/staging' row format delimited fields terminated by ',' select * from hugetable;
Note that this may create multiple files and you may want to concatenate them on the client side after it's done exporting.
Using this approach means you don't need to worry about the format of the source tables, can export based on arbitrary SQL query, and can select your own delimiters and output formats.
While LIKE
is suitable for this case, a more general purpose solution is to use instr
, which doesn't require characters in the search string to be escaped. Note: instr
is available starting from Sqlite 3.7.15.
SELECT *
FROM TABLE
WHERE instr(column, 'cats') > 0;
Also, keep in mind that LIKE
is case-insensitive, whereas instr
is case-sensitive.

Two slices can be concatenated using append
method in the standard golang library. Which is similar to the variadic
function operation. So we need to use ...
package main
import (
"fmt"
)
func main() {
x := []int{1, 2, 3}
y := []int{4, 5, 6}
z := append([]int{}, append(x, y...)...)
fmt.Println(z)
}
output of the above code is: [1 2 3 4 5 6]
"2.7.0_bf4fda703454".split("_")
gives a list of strings:
In [1]: "2.7.0_bf4fda703454".split("_")
Out[1]: ['2.7.0', 'bf4fda703454']
This splits the string at every underscore. If you want it to stop after the first split, use "2.7.0_bf4fda703454".split("_", 1)
.
If you know for a fact that the string contains an underscore, you can even unpack the LHS and RHS into separate variables:
In [8]: lhs, rhs = "2.7.0_bf4fda703454".split("_", 1)
In [9]: lhs
Out[9]: '2.7.0'
In [10]: rhs
Out[10]: 'bf4fda703454'
An alternative is to use partition()
. The usage is similar to the last example, except that it returns three components instead of two. The principal advantage is that this method doesn't fail if the string doesn't contain the separator.
As an alternative to using clip you could also use {border-radius: 0.0001px}
on a parent element. It works not only with absolute/fixed positioned elements.

I'm surprised that no one mentioned matplot
. It's pretty convenient in case you don't need to plot each line in separate axes.
Just one command:
matplot(y = data, type = 'l', lty = 1)
Use ?matplot
to see all the options.
To add the legend, you can set color palette and then add it:
mypalette = rainbow(ncol(data))
matplot(y = data, type = 'l', lty = 1, col = mypalette)
legend(legend = colnames(data), x = "topright", y = "topright", lty = 1, lwd = 2, col = mypalette)

For me the better solution was the following. Since the initiative of closing the connection was done by the server, the setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
had no effect and the TIME_WAIT was avoiding a new connection on the same port with error:
[Errno 10048]: Address already in use. Only one usage of each socket address (protocol/IP address/port) is normally permitted
I finally used the solution to let the OS choose the port itself, then another port is used if the precedent is still in TIME_WAIT.
I replaced:
self._socket.bind((guest, port))
with:
self._socket.bind((guest, 0))
As it was indicated in the python socket documentation of a tcp address:
If supplied, source_address must be a 2-tuple (host, port) for the socket to bind to as its source address before connecting. If host or port are ‘’ or 0 respectively the OS default behavior will be used.
Another solution with .loc:
df = pd.DataFrame({'col': ['a', 0]})
df.loc[df.index, 'col'] = 'string' + df['col'].astype(str)
This is not as quick as solutions above (>1ms per loop slower) but may be useful in case you need conditional change, like:
mask = (df['col'] == 0)
df.loc[mask, 'col'] = 'string' + df['col'].astype(str)
You need to pass the variable into the function:
$data = 'My data';
function menugen($data)
{
echo $data;
}
This is to ensure some other site can't do nasty tricks to try to steal your data. For example, by replacing the array constructor, then including this JSON URL via a <script>
tag, a malicious third-party site could steal the data from the JSON response. By putting a while(1);
at the start, the script will hang instead.
A same-site request using XHR and a separate JSON parser, on the other hand, can easily ignore the while(1);
prefix.
try this :

If you have problems with fetch --all
then track your remote branch:
git checkout --track origin/%branchname%
The main difference is that sorted(some_list)
returns a new list
:
a = [3, 2, 1]
print sorted(a) # new list
print a # is not modified
and some_list.sort()
, sorts the list in place:
a = [3, 2, 1]
print a.sort() # in place
print a # it's modified
Note that since a.sort()
doesn't return anything, print a.sort()
will print None
.
Can a list original positions be retrieved after list.sort()?
No, because it modifies the original list.
Where you say you're changing the value of the first element;
x = Integer.valueOf(9);
You're changing x
to point to an entirely new Integer, but never using it again. You're not changing the collection in any way.
Since you're working with ArrayList, you can use ListIterator if you want an iterator that allows you to change the elements, this is the snippet of your code that would need to be changed;
//initialize the Iterator
ListIterator<Integer> i = a.listIterator();//changed the value of frist element in List
if(i.hasNext()) {
i.next();
i.set(Integer.valueOf(9)); // Change the element the iterator is currently at
}// New iterator, and print all the elements
Iterator iter = a.iterator();
while(iter.hasNext())
System.out.print(iter.next());>> 912345678
Sadly the same cannot be extended to other collections like Set<T>. Implementation details (a HashSet for example being implemented as a hash table and changing the object could change the hash value and therefore the iteration order) makes Set<T> a "add new/remove only" type of data structure, and changing the content at all while iterating over it is not safe.
Arrays.asList
is the handy function available in Java to convert an array variable to List or Collection. For better under standing consider the below example:
package com.stackoverflow.works;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class Wetland {
private String name;
private List<String> species = new ArrayList<String>();
public Wetland(String name, String[] speciesArr) {
this.name = name;
this.species = Arrays.asList(speciesArr);
}
public void display() {

In Laravel 5.1, I used: File: app\Providers\AppServiceProvider.php
public function boot()
{
if ($this->isSecure()) {
\URL::forceSchema('https');
}
}
public function isSecure()
{
$isSecure = false;
if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') {
$isSecure = true;
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https' || !empty($_SERVER['HTTP_X_FORWARDED_SSL']) && $_SERVER['HTTP_X_FORWARDED_SSL'] == 'on') {
$isSecure = true;
}
return $isSecure;

NOTE: use forceSchema
, NOT forceScheme
You need to decode data from input string into unicode, before using it, to avoid encoding problems.
field.text = data.decode("utf8")
Try something like:
CREATE FUNCTION ColumnExists(@TableName varchar(100), @ColumnName varchar(100))
RETURNS varchar(1) AS
BEGIN
DECLARE @Result varchar(1);
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.Columns WHERE TABLE_NAME = @TableName AND COLUMN_NAME = @ColumnName)
BEGIN
SET @Result = 'T'
END
ELSE
BEGIN
SET @Result = 'F'
END
RETURN @Result;
END
GO
GRANT EXECUTE ON [ColumnExists] TO [whoever]
GO
Then use it like this:
IF ColumnExists('xxx', 'yyyy') = 'F'
BEGIN
ALTER TABLE xxx
ADD yyyyy varChar(10) NOT NULL
END
GO
It should work on both SQL Server 2000 & SQL Server 2005. Not sure about SQL Server 2008, but don't see why not.
Create an array to store the objects:
ArrayList<MyObject> list = new ArrayList<MyObject>();
In a single step:
list.add(new MyObject (1, 2, 3)); //Create a new object and adding it to list.
or
MyObject myObject = new MyObject (1, 2, 3); //Create a new object.
list.add(myObject); // Adding it to the list.
If your Local branch and remote branch is the same name then you can just do it:
git push origin branchName
When your local and remote branch name is different then you can just do it:
git push origin localBranchName:remoteBranchName
Try this
$_SERVER['HTTP_CF_CONNECTING_IP'];
instead of
$_SERVER["REMOTE_ADDR"];
Find a better use for myself: I usually test if a variant is empty, and all of the above methods fail with the test. I found that you can actually set a variant to empty:
Dim aTable As Variant
If IsEmpty(aTable) Then
'This is true
End If
ReDim aTable(2)
If IsEmpty(aTable) Then
'This is False
End If
ReDim aTable(2)
aTable = Empty
If IsEmpty(aTable) Then
'This is true
End If
ReDim aTable(2)
Erase aTable
If IsEmpty(aTable) Then
'This is False
End If
this way i get the behaviour i want
First of all it is not recommended to have php files with functions in design folder. You should create a new module or extend (copy from core to local a helper and add function onto that class) and do not change files from app/code/core.
To answer to your question you can use:
require(Mage::getBaseDir('design').'/frontend/default/mytheme/myfunc.php');
Best practice (as a start) will be to create in /app/code/local/Mage/Core/Helper/Extra.php a php file:
<?php
class Mage_Core_Helper_Extra extends Mage_Core_Helper_Abstract
{
public function getSomething()
{
return 'Someting';
}
}
And to use it in phtml files use:
$this->helper('core/extra')->getSomething();
Or in all the places:
Mage::helper('core/extra')->getSomething();
Found one solution for WIFI (works for Android 4.3, 4.4):
Actually, you have to use the anchor # to play with this. If you reverse engineer the Gmail url system, you'll find
https://mail.google.com/mail/u/0/#inbox
https://mail.google.com/mail/u/0/#inbox?compose=new
Everything after # is the part your want to load in your page, then you just have to chose where to load it.
By the way, using document.location by adding a #something won't refresh your page.
your fadeIn()
function calls the fadeOut()
function, which calls the fadeIn()
function again. the recursion is in the JS.
Check this one out, too:
$(document).ready(function() {
if($("input:radio[name='yourRadioGroupName'][value='yourvalue']").is(":checked")) {
//its checked
}
});
Date
is Comparable
so just create list of List<Date>
and sort it using Collections.sort()
. And use Collections.reverseOrder()
to get comparator in reverse ordering
.
From Java Doc
Returns a comparator that imposes the reverse ordering of the specified comparator. If the specified comparator is null, this method is equivalent to reverseOrder() (in other words, it returns a comparator that imposes the reverse of the natural ordering on a collection of objects that implement the Comparable interface).
The solution is inspired from the below solution by @marco. I have also updated his answer with these datails.
The problem here is about lazy loading of the sub-objects, where Jackson only finds hibernate proxies, instead of full blown objects.
So we are left with two options - Suppress the exception, like done above in most voted answer here, or make sure that the LazyLoad objects are loaded.
If you choose to go with latter option, solution would be to use jackson-datatype library, and configure the library to initialize lazy-load dependencies prior to the serialization.
I added a new config class to do that.
@Configuration
public class JacksonConfig extends WebMvcConfigurerAdapter {
@Bean
@Primary
public MappingJackson2HttpMessageConverter jacksonMessageConverter(){
MappingJackson2HttpMessageConverter messageConverter = new MappingJackson2HttpMessageConverter();
ObjectMapper mapper = new ObjectMapper();
Hibernate5Module module = new Hibernate5Module();
module.enable(Hibernate5Module.Feature.FORCE_LAZY_LOADING);
mapper.registerModule(module);
messageConverter.setObjectMapper(mapper);
return messageConverter;
}
}
@Primary
makes sure that no other Jackson config is used for initializing any other beans. @Bean
is as usual. module.enable(Hibernate5Module.Feature.FORCE_LAZY_LOADING);
is to enable Lazy loading of the dependencies.
Caution - Please watch for its performance impact. sometimes EAGER fetch helps, but even if you make it eager, you are still going to need this code, because proxy objects still exist for all other Mappings except @OneToOne
PS : As a general comment, I would discourage the practice of sending whole data object back in the Json response, One should be using Dto's for this communication, and use some mapper like mapstruct to map them. This saves you from accidental security loopholes, as well as above exception.
With Linq
var newList = GlobalStrings.Append(localStrings)
Warning
If you run PowerShell from a cmd.exe window created by Powershell, the 2nd instance no longer waits for jobs to complete.
cmd> PowerShell
PS> Start-Process cmd.exe -Wait
Now from the new cmd window, run PowerShell again and within it start a 2nd cmd window: cmd2> PowerShell
PS> Start-Process cmd.exe -Wait
PS>
The 2nd instance of PowerShell no longer honors the -Wait request and ALL background process/jobs return 'Completed' status even thou they are still running !
I discovered this when my C# Explorer program is used to open a cmd.exe window and PS is run from that window, it also ignores the -Wait request. It appears that any PowerShell which is a 'win32 job' of cmd.exe fails to honor the wait request.
I ran into this with PowerShell version 3.0 on windows 7/x64
There are two setting.xml in windows.
%MAVEN_HOME%\conf\
%userprofile%\.m2\
If %userprofile%\.m2\setting.xml
takes effect, maven will not access %MAVEN_HOME%\conf\setting.xml
.

Contrary to what pointy says, the blur()
method does exist and is a part of the w3c standard. The following exaple will work in every modern browser (including IE):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Javascript test</title>
<script type="text/javascript" language="javascript">
window.onload = function()
{
var field = document.getElementById("field");
var link = document.getElementById("link");
var output = document.getElementById("output");
field.onfocus = function() { output.innerHTML += "<br/>field.onfocus()"; };
field.onblur = function() { output.innerHTML += "<br/>field.onblur()"; };
link.onmouseover = function() { field.blur(); };
};
</script>
</head>
<body>
<form name="MyForm">
<input type="text" name="field" id="field" />
<a href="javascript:void(0);" id="link">Blur field on hover</a>
<div id="output"></div>
</form>
</body>
</html>
Note that I used link.onmouseover
instead of link.onclick
, because otherwise the click itself would have removed the focus.
I would like to point out that none of the T-SQL on this page will work precisely because none of them join to the syssessions table to get only the current session and therefore could include false positives.
See this for reference: What does it mean to have jobs with a null stop date?
You can also validate this by analyzing the sp_help_jobactivity procedure in msdb.
I realize that this is an old message on SO, but I found this message only partially helpful because of the problem.
SELECT
job.name,
job.job_id,
job.originating_server,
activity.run_requested_date,
DATEDIFF( SECOND, activity.run_requested_date, GETDATE() ) as Elapsed
FROM
msdb.dbo.sysjobs_view job
JOIN
msdb.dbo.sysjobactivity activity
ON
job.job_id = activity.job_id
JOIN
msdb.dbo.syssessions sess
ON
sess.session_id = activity.session_id
JOIN
(
SELECT
MAX( agent_start_date ) AS max_agent_start_date
FROM
msdb.dbo.syssessions
) sess_max
ON
sess.agent_start_date = sess_max.max_agent_start_date
WHERE
run_requested_date IS NOT NULL AND stop_execution_date IS NULL
You could also do something as follow
public enum DAY {MON, TUES, WED, THU, FRI, SAT, SUN};
EnumSet.allOf(DAY.class).stream().map(e -> e.name()).collect(Collectors.toList())
or
EnumSet.allOf(DAY.class).stream().map(DAY::name).collect(Collectors.toList())
The main reason why I stumbled across this question is that I wanted to write a generic validator that validates whether a given string enum name is valid for a given enum type (Sharing in case anyone finds useful).
For the validation, I had to use Apache's EnumUtils
library since the type of enum is not known at compile time.
@SuppressWarnings({ "unchecked", "rawtypes" })
public static void isValidEnumsValid(Class clazz, Set<String> enumNames) {
Set<String> notAllowedNames = enumNames.stream()
.filter(enumName -> !EnumUtils.isValidEnum(clazz, enumName))
.collect(Collectors.toSet());
if (notAllowedNames.size() > 0) {
String validEnumNames = (String) EnumUtils.getEnumMap(clazz).keySet().stream()
.collect(Collectors.joining(", "));
throw new IllegalArgumentException("The requested values '" + notAllowedNames.stream()
.collect(Collectors.joining(",")) + "' are not valid. Please select one more (case-sensitive) "
+ "of the following : " + validEnumNames);
}
}
I was too lazy to write an enum annotation validator as shown in here https://stackoverflow.com/a/51109419/1225551
Windows is obviously not written in C# (!)
Simply see the source code of Windows and you'll see...
Swift 5:
When deal with collectionView. Reloading only 1 item or several items with animation. I try some different animation options when changing cell image, no difference, so I don't indicate animation name here.
UIView.animate(withDuration: 1.0) { [weak self] in
guard let self = self else { return print("gotchya!") }
self.collectionView.reloadItems(at: [indexPath])
}
A better use of jAndy's answer to implement a polling function that polls every interval
seconds, and ends after timeout
seconds.
function pollFunc(fn, timeout, interval) {
var startTime = (new Date()).getTime();
interval = interval || 1000;
(function p() {
fn();
if (((new Date).getTime() - startTime ) <= timeout) {
setTimeout(p, interval);
}
})();
}
pollFunc(sendHeartBeat, 60000, 1000);
UPDATE
As per the comment, updating it for the ability of the passed function to stop the polling:
function pollFunc(fn, timeout, interval) {
var startTime = (new Date()).getTime();
interval = interval || 1000,
canPoll = true;
(function p() {
canPoll = ((new Date).getTime() - startTime ) <= timeout;
if (!fn() && canPoll) { // ensures the function exucutes
setTimeout(p, interval);
}
})();
}
pollFunc(sendHeartBeat, 60000, 1000);
function sendHeartBeat(params) {
...
...
if (receivedData) {
// no need to execute further
return true; // or false, change the IIFE inside condition accordingly.
}
}
ICYMI: Included on the new features for C# 7.0 enumerated here, "discards" is now allowed as out parameters in the form of a _, to let you ignore out parameters you don’t care about:
p.GetCoordinates(out var x, out _); // I only care about x
P.S. if you're also confused with the part "out var x", read the new feature about "Out Variables" on the link as well.
Tony is a pure genius. However to achieve even better auto-completion try setting the triggers to this:
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz =.(!+-*/~,[{@#$%^&
(specifically aranged in order of usage for faster performance :)
