To avoid any ambiguity, use the utilities methods from SwingUtilities :
SwingUtilities.isLeftMouseButton(MouseEvent anEvent)
SwingUtilities.isRightMouseButton(MouseEvent anEvent)
SwingUtilities.isMiddleMouseButton(MouseEvent anEvent)
If you're using a Unix like OS (Linux, OSX, etc) then you can use a combination of find
and egrep
to search for require statements containing your package name:
find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni 'name-of-package' {} \;
If you search for the entire require('name-of-package')
statement, remember to use the correct type of quotation marks:
find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni 'require("name-of-package")' {} \;
or
find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni "require('name-of-package')" {} \;
The downside is that it's not fully automatic, i.e. it doesn't extract package names from package.json
and check them. You need to do this for each package yourself. Since package.json
is just JSON this could be remedied by writing a small script that uses child_process.exec
to run this command for each dependency. And make it a module. And add it to the NPM repo...
Is there anything wrong with
new Dictionary<KeyValuePair<object, object>, object>?
There's no "direct" way of doing so but you can specify the pattern twice as in: a[^a]*a
that match up to the second "a".
The alternative is to use your programming language (perl? C#? ...) to match the first occurence and then the second one.
EDIT: I've seen other responded using the "non-greedy" operators which might be a good way to go, assuming you have them in your regex library!
I tried almost all the listed solutions, none worked for me until I restarted the machine and then mysql server restarted when I issued the command "service mysql restart".
A programmer solution:
const int RADIUS = 64;
const int MATRIX_SIZE = RADIUS * 2;
bool matrix[MATRIX_SIZE][MATRIX_SIZE] = {0};
struct Point { int x; int y; };
Point lookupTable[MATRIX_SIZE * MATRIX_SIZE];
void init()
{
int numberOfOnBits = 0;
for (int x = 0 ; x < MATRIX_SIZE ; ++x)
{
for (int y = 0 ; y < MATRIX_SIZE ; ++y)
{
if (x * x + y * y < RADIUS * RADIUS)
{
matrix[x][y] = true;
loopUpTable[numberOfOnBits].x = x;
loopUpTable[numberOfOnBits].y = y;
++numberOfOnBits;
} // if
} // for
} // for
} // ()
Point choose()
{
int randomIndex = randomInt(numberOfBits);
return loopUpTable[randomIndex];
} // ()
The bitmap is only necessary for the explanation of the logic. This is the code without the bitmap:
const int RADIUS = 64;
const int MATRIX_SIZE = RADIUS * 2;
struct Point { int x; int y; };
Point lookupTable[MATRIX_SIZE * MATRIX_SIZE];
void init()
{
int numberOfOnBits = 0;
for (int x = 0 ; x < MATRIX_SIZE ; ++x)
{
for (int y = 0 ; y < MATRIX_SIZE ; ++y)
{
if (x * x + y * y < RADIUS * RADIUS)
{
loopUpTable[numberOfOnBits].x = x;
loopUpTable[numberOfOnBits].y = y;
++numberOfOnBits;
} // if
} // for
} // for
} // ()
Point choose()
{
int randomIndex = randomInt(numberOfBits);
return loopUpTable[randomIndex];
} // ()
You should find them by default in a folder like /etc/my.cnf
, maybe also depends on versions. From MySQL Configuration File:
Interestingly, the scope of this file can be set according to its location. The settings will be considered global to all MySQL servers if stored in /etc/my.cnf. It will be global to a specific server if located in the directory where the MySQL databases are stored (/usr/local/mysql/data for a binary installation, or /usr/local/var for a source installation). Finally, its scope could be limited to a specific user if located in the home directory of the MySQL user (~/.my.cnf). Keep in mind that even if MySQL does locate a my.cnf file in /etc/my.cnf (global to all MySQL servers on that machine), it will continue its search for a server-specific file, and then a user-specific file. You can think of the final configuration settings as being the result of the /etc/my.cnf, mysql-data-dir/my.cnf, and ~/.my.cnf files.
There are a few switches to package managers to list specific files.
RPM Sytems:
There are switches to rpm
command, -q
for query, and -c
or --configfiles
to list config files. There is also -l
or --list
The --configfiles
one didn't quiet work for me, but --list
did list a few .cnf
files held by mysql-server
rpm -q --list mysql-server
DEB Systems:
Also with limited success: dpkg --listfiles mysql-server
Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.
I just tested (should have done that first), and something like ng-show="!a && b"
worked as expected.
To be agnostic, drop back and punt.
Select a.name as a_name, r.name as r_name
from ApplicationsResource ar, Applications a, Resources r
where a.id = ar.app_id
and r.id = ar.resource_id
order by r.name, a.name;
Now user your server programming language to concatenate a_names while r_name is the same as the last time.
I'm not a WCF expert but I'm wondering if you aren't running into a DDOS protection on IIS. I know from experience that if you run a bunch of simultaneous connections from a single client to a server at some point the server stops responding to the calls as it suspects a DDOS attack. It will also hold the connections open until they time-out in order to slow the client down in his attacks.
Multiple connection coming from different machines/IP's should not be a problem however.

I usually do:
import datetime

Even if i do not recommend putting Laravel on the root folder there are some cases when it could not be avoided; for those cases the above methods do not work for assets so i made a quick fix changing the htaccess: after copying server.php to index.php edit the .htaccess file like so:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
### fix file rewrites on root path ###
#select file url
RewriteCond %{REQUEST_URI} ^(.*)$
#if file exists in /public/<filename>
RewriteCond %{DOCUMENT_ROOT}/public/$1 -f
#redirect to /public/<filename>
RewriteRule ^(.*)$ public/$1 [L]
###############
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
#RewriteCond %{REQUEST_FILENAME} -d # comment this rules or the user will read non-public file and folders!
#RewriteCond %{REQUEST_FILENAME} -f #
RewriteRule ^ index.php [L]
</IfModule>
This was a quick fix i had to make so anyone is welcome to upgrade it.
A clustered index is essentially a sorted copy of the data in the indexed columns.
The main advantage of a clustered index is that when your query (seek) locates the data in the index then no additional IO is needed to retrieve that data.
The overhead of maintaining a clustered index, especially in a frequently updated table, can lead to poor performance and for that reason it may be preferable to create a non-clustered index.

I found another solution for new Sonar versions where JaCoCo's binary report format (*.exec) was deprecated and the preferred format is XML (SonarJava 5.12 and higher). The solution is very simple and similar to the previous solution with *.exec reports in parent directory from this topic: https://stackoverflow.com/a/15535970/4448263.
Assuming that our project structure is:
moduleC - aggregate project's pom
|- moduleA - some classes without tests
|- moduleB - some classes depending from moduleA and tests for classes in both modules: moduleA and moduleB
You need following maven build plugin configuration in aggregate project's pom:
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.5</version>
<executions>
<execution>
<id>prepare-and-report</id>
<goals>
<goal>prepare-agent</goal>
<goal>report</goal>
</goals>
</execution>
<execution>
<id>report-aggregate</id>
<phase>verify</phase>
<goals>
<goal>report-aggregate</goal>
</goals>
<configuration>
<outputDirectory>${project.basedir}/../target/site/jacoco-aggregate</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
Then build project with maven:
mvn clean verify
And for Sonar you should set property in administration GUI:
sonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml,../target/site/jacoco-aggregate/jacoco.xml
or using command line:
mvn sonar:sonar -Dsonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml,../target/site/jacoco-aggregate/jacoco.xml
Description
This creates binary reports for each module in default directories: target/jacoco.exec
. Then creates XML reports for each module in default directories: target/site/jacoco/jacoco.xml
. Then creates an aggregate report for each module in custom directory ${project.basedir}/../target/site/jacoco-aggregate/
that is relative to parent directory for each module. For moduleA and moduleB this will be common path moduleC/target/site/jacoco-aggregate/
.
As moduleB depends on moduleA, moduleB will be built last and its report will be used as an aggregate coverage report in Sonar for both modules A and B.
In addition to the aggregate report, we need a normal module report as JaCoCo aggregate reports contain coverage data only for dependencies.
Together, these two types of reports providing full coverage data for Sonar.
There is one little restriction: you should be able to write a report in the project's parent directory (should have permission). Or you can set property jacoco.skip=true
in root project's pom.xml (moduleC) and jacoco.skip=false
in modules with classes and tests (moduleA and moduleB).
If you are working on the mongo shell, Please refer this : Answer from Tyler Brock
I wrote the answer if you are using mongodb using node.js
You don't need to convert the id into an ObjectId
. Just use :
db.collection.findById('4ecbe7f9e8c1c9092c000027');
this collection method will automatically convert id into ObjectId.
On the other hand :
db.collection.findOne({"_id":'4ecbe7f9e8c1c9092c000027'})
doesn't work as expected. You've manually convert id into ObjectId
.
That can be done like this :
let id = '58c85d1b7932a14c7a0a320d';
let o_id = new ObjectId(id); // id as a string is passed
db.collection.findOne({"_id":o_id});
Instead of return false, you could try event.preventDefault(); like this:
$(function() {
$('#registerform').submit(function(event) {
event.preventDefault();
$(this).submit();
});
});
The one mahesh posted is not working because the attribute name is missing:
So instead of
<input id="list" class="required" />
You can use:
<input id="list" name="list" class="required" />
As well as updating the manifest, update the module's build.gradle
file too (it's listed in the project pane just below the manifest - if there's no minSdkVersion
key in it, you're looking at the wrong one, as there's a couple). A rebuild and things should be fine...
to create date from any string use:
$date = DateTime::createFromFormat('d-m-y H:i', '01-01-01 01:00');
echo $date->format('Y-m-d H:i');
Update MVC 5.1 now supports the below approach directly, so it works for built in editor too. http://www.asp.net/mvc/overview/releases/mvc51-release-notes#new-features (It's either a case of Great mind thinking alike or they read my answer :)
End Update
If your using your own editor template or with MVC 5.1 which now supports the below approach directly for built in editors.
@Html.EditorFor(modelItem => item.YourProperty,
new { htmlAttributes = new { @class="verificationStatusSelect", style = "Width:50px" } })
then in your template (not required for simple types in MVC 5.1)
@Html.TextBoxFor(m => m, ViewData["htmlAttributes"])
As long as Event_ID is Integer, do this:
INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, (Event_ID + 155)
FROM Table
WHERE Event_ID = "120"
you can open your trigger with sp_helptext yourtriggername
C# has a static constructor for this purpose.
static class YourClass
{
static YourClass()
{
// perform initialization here
}
}
From MSDN:
A static constructor is used to initialize any static data, or to perform a particular action that needs to be performed once only. It is called automatically before the first instance is created or any static members are referenced

For a typical XAMPP install on windows you probably have the php_sockets.dll in your C:\xampp\php\ext directory. All you got to do is go to php.ini in the C:\xampp\php directory and change the ;extension=php_sockets.dll
to extension=php_sockets.dll
.
Under Rails, arrays and hashes in Ruby have built-in to_json functions. I would use JSON just because it is very readable within a web browser, e.g. Google Chrome.
That being said if you are concerned about it looking too "tech looking" you should probably write your own function that replaces the curly braces and square braces in your hashes and arrays with white-space and other characters.
Look up the gsub function for a very good way to do it. Keep playing around with different characters and different amounts of whitespace until you find something that looks appealing. http://ruby-doc.org/core-1.9.3/String.html#method-i-gsub
Another iteration on the SetCscope() function above. That sets cscope pre-path to get matches without being on the dir where "cscope.out" is:
function s:FindFile(file)
let curdir = getcwd()
let found = curdir
while !filereadable(a:file) && found != "/"
cd ..
let found = getcwd()
endwhile
execute "cd " . curdir
return found
endfunction
if has('cscope')
let $CSCOPE_DIR=s:FindFile("cscope.out")
let $CSCOPE_DB=$CSCOPE_DIR."/cscope.out"
if filereadable($CSCOPE_DB)
cscope add $CSCOPE_DB $CSCOPE_DIR
endif
command -nargs=0 Cscope !cscope -ub -R &
endif
You can always do something like this:
update mytable t
set SomeColumn = c.ComputedValue
from (select *, 42 as ComputedValue from mytable where id = 1) c
where t.id = c.id
You can now also use with statement inside update
update mytable t
set SomeColumn = c.ComputedValue
from (with abc as (select *, 43 as ComputedValue_new from mytable where id = 1
select *, 42 as ComputedValue, abc.ComputedValue_new from mytable n1
inner join abc on n1.id=abc.id) c
where t.id = c.id

// Inputs
boolean filteredFile = false;
// Ouput
final ArrayList<File> output = new ArrayList<File> ();

Common sense works here: os
is a module, and os.path
is a module, too. So just import the module you want to use:
If you want to use functionalities in the os
module, then import os
.
If you want to use functionalities in the os.path
module, then import os.path
.
If you want to use functionalities in both modules, then import both modules:
import os
import os.path
For reference:
Lib/idlelib/rpc.py uses os
and imports os
.
Lib/idlelib/idle.py uses os.path
and imports os.path
.
Lib/ensurepip/init.py uses both and imports both.
Note: If you're using AngularJS, then in addition to changing the step value, you may have to set ng-model-options="{updateOn: 'blur change'}"
on the html input.
The reason for this is in order to have the validators run less often, as they are preventing the user from entering a decimal point. This way, the user can type in a decimal point and the validators go into effect after the user blurs.
Using the following 1 line command for changing many files name in linux using phrase specificity:
find -type f -name '*.jpg' | rename 's/holiday/honeymoon/'
For all files with the extension ".jpg", if they contain the string "holiday", replace it with "honeymoon". For instance, this command would rename the file "ourholiday001.jpg" to "ourhoneymoon001.jpg".
This example also illustrates how to use the find command to send a list of files (-type f) with the extension .jpg (-name '*.jpg') to rename via a pipe (|). rename then reads its file list from standard input.
Page_Load happens after ViewState and PostData is sent into all of your server side controls by ASP.NET controls being created on the page. Page_Init is the event fired prior to ViewState and PostData being reinstated. Page_Load is where you typically do any page wide initilization. Page_PreRender is the last event you have a chance to handle prior to the page's state being rendered into HTML. Page_Load is the more typical event to work with.

If using Subdomains, for example like "pt.mydomain.com" to set portuguese for example, using Application_AcquireRequestState won't work, because it's not called on subsequent cache requests.
To solve this, I suggest an implementation like this:
Add the VaryByCustom parameter to the OutPutCache like this:
[OutputCache(Duration = 10000, VaryByCustom = "lang")]
public ActionResult Contact()
{
return View("Contact");
}
In global.asax.cs, get the culture from the host using a function call:
protected void Application_AcquireRequestState(object sender, EventArgs e)
{
System.Threading.Thread.CurrentThread.CurrentUICulture = GetCultureFromHost();
}
Add the GetCultureFromHost function to global.asax.cs:
private CultureInfo GetCultureFromHost()
{
CultureInfo ci = new CultureInfo("en-US"); // en-US
string host = Request.Url.Host.ToLower();
if (host.Equals("mydomain.com"))
{
ci = new CultureInfo("en-US");
}
else if (host.StartsWith("pt."))
{
ci = new CultureInfo("pt");
}
else if (host.StartsWith("de."))
{
ci = new CultureInfo("de");
}
else if (host.StartsWith("da."))
{
ci = new CultureInfo("da");
}
return ci;
}
And finally override the GetVaryByCustomString(...) to also use this function:

The function Application_AcquireRequestState is called on non-cached calls, which allows the content to get generated and cached. GetVaryByCustomString is called on cached calls to check if the content is available in cache, and in this case we examine the incoming host domain value, again, instead of relying on just the current culture info, which could have changed for the new request (because we are using subdomains).

Could you give some detail of the problem you are facing? Then we might have a chance of helping you. Otherwise we would just be guessing what the problem is you are having.
It may be because of the installation of Cors nuget packages.
If you facing the problem after installing and enabaling cors from nuget , then you may try reinstalling web Api.
From the package manager, run Update-Package Microsoft.AspNet.WebApi -reinstall
You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.
There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).
This is no longer up-to-date!
Push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:
git config --global push.default matching
To squelch this message and adopt the new behavior now, use:
git config --global push.default simple
When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.
Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.
Using the -clean
option is the way to go, as mentioned by the other answers.
Make sure that you remove it from your .ini
or shortcut after you've fixed the problem. It causes Eclipse to reevaluate all of the plugins everytime it starts and can dramatically increase startup time, depending on how many Eclipse plugins you have installed.
\b matches a word boundary. I think you can use ^$ for empty string.
It's easy to believe that deleting the whole Subversion repository requires "informing" Subversion that you're going to delete the repository. But Subversion only cares about managing a repository once it's created, not whether the repository exists or not ( if that makes sense ). It goes like this: the Subversion tools and commands are not adversely affected by just deleting your repository directory with the regular operating system utilities (like rm -R). A repository directory is not the same thing as an installed program directory, where deleting a program without uninstalling it might leave behind erratic config files or other dependencies. A repository is 100% self-contained in its directory, and deleting it is harmless (besides losing your project history). You just clean the slate to create a new Subversion repository and import your next project.

Hoping to help anyone. :)
The key information is written in @Sam's answer but not really salient, so let's make it clear.
The line which appears even without -v
switch:
ssh: connect to host (some host or IP address) port 22: Bad file number
is actually irrelevant.
If you focus on it you'll waste your time as it is not a hint about what the actual problem is, just an effect of running git's ssh on Windows. It's not even a sign that the git or ssh install or configuration is wrong. Really, ignore it.
The very same command on Linux produced instead this message for me, which gave an actual hint about the problem:
ssh: connect to host (some host or IP address) port 22: Connection timed out
Focus on lines being added with -v
on command line. In my case it was:
debug1: connect to address (some host or IP address) port 22: Attempt to connect timed out without establishing a connection
My problem was a typo in the IP address, but yours may be different.
If someone can prove that "bad file number" only appears when the actual reason is "connection time out" then it makes some sense to address why connection could time out.
Until that, "bad file number" is only a generic error message and this question is fully answered by saying "ignore it and look for other error messages".
EDIT: Qwertie mentioned that the error message is indeed generic, as it can happen on "Connection refused" also. This confirms the analysis.
Please don't clutter this question with general hints and answer, they have nothing to do with the actual topic (and title) of this question which is "Git SSH error: “Connect to host: Bad file number”". If using -v
you have more informative message that deserve their own question, then open another question, then you can make a link to it.
Correct attribute value for Asp.Net MVC Core to prevent browser caching (including Internet Explorer 11) is:
[ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]
as described in Microsoft documentation:
Response caching in ASP.NET Core - NoStore and Location.None
The simplest way to do this is to add the .config
file in the deployment section on your unit test.
To do so, open the .testrunconfig
file from your Solution Items. In the Deployment section, add the output .config
files from your project's build directory (presumably bin\Debug
).
Anything listed in the deployment section will be copied into the test project's working folder before the tests are run, so your config-dependent code will run fine.
Edit: I forgot to add, this will not work in all situations, so you may need to include a startup script that renames the output .config
to match the unit test's name.

Took the following code from php manual for get_browser.
$browser = get_browser(null, true);
print_r($browser);
The $browser

The documentation for START_STICKY
and START_NOT_STICKY
is quite straightforward.
If this service's process is killed while it is started (after returning from
onStartCommand(Intent, int, int))
, then leave it in the started state but don't retain this delivered intent. Later the system will try to re-create the service. Because it is in the started state, it will guarantee to callonStartCommand(Intent, int, int)
after creating the new service instance; if there are not any pending start commands to be delivered to the service, it will be called with a null intent object, so you must take care to check for this.This mode makes sense for things that will be explicitly started and stopped to run for arbitrary periods of time, such as a service performing background music playback.
Example: Local Service Sample
If this service's process is killed while it is started (after returning from
onStartCommand(Intent, int, int))
, and there are no new start intents to deliver to it, then take the service out of the started state and don't recreate until a future explicit call toContext.startService(Intent)
. The service will not receive aonStartCommand(Intent, int, int)
call with anull
Intent because it will not be re-started if there are no pending Intents to deliver.This mode makes sense for things that want to do some work as a result of being started, but can be stopped when under memory pressure and will explicit start themselves again later to do more work. An example of such a service would be one that polls for data from a server: it could schedule an alarm to poll every
N
minutes by having the alarm start its service. When itsonStartCommand(Intent, int, int)
is called from the alarm, it schedules a new alarm for N minutes later, and spawns a thread to do its networking. If its process is killed while doing that check, the service will not be restarted until the alarm goes off.
Example: ServiceStartArguments.java
Here is the simple one line fix without css.

I would use a decimal with the proper precision for your data.
I had also the similar issue in godaddy hosting. But after putting ob_start(); at the beginning of the php page from where page was redirecting, it was working fine.
Please find the example of the fix:
fileName:index.php
<?php
ob_start();
...
header('Location: page1.php');
...
ob_end_flush();
?>
I Had the same problem, in my case, was because i was returned a digit:
def __str__(self):
return self.code
str is waiting for a str, not another.
now work good with:
def __str__(self):
return self.name
where name is a STRING.
If you plan on integrating app functionality with a website, I'd highly recommend the GWT + PhoneGap model:
http://blog.daniel-kurka.de/2012/02/mgwt-and-phonegap-talk-at-webmontag-in.html http://turbomanage.wordpress.com/2010/09/24/gwt-phonegap-native-mobile-apps-quickly/
Here's my two cents from my own experience: We use the same Java POJOs for our Hibernate database, our REST API, our website, and our iPhone app. The workflow is simple and beautiful:
Database ---1---> REST API ---2---> iPhone App / Website
There is another benefit to this approach as well - any Java code that can be compiled with GWT and any JavaScript library become available for use in your iPhone app.
Replace all the spaces in the String with empty character.
String lineWithoutSpaces = line.replaceAll("\\s+","");
There is no way to configure an exclusion to the proxy settings, but a colleague of mine had an create solution for that particular problem. He installed a local proxy server called cntlm. That server supports ntlm authentication and exclusions to the general proxy settings. A perfect match.
After doing some testing, i came up with this solution, let me know in case it helps.
Add this below 2 conditions in your query and it will find the records which don't contain numeric data
and REGEXP_LIKE(<column_name>, '\D') -- this selects non numeric data
and not REGEXP_LIKE(column_name,'^[-]{1}\d{1}') -- this filters out negative(-) values
Applying s_ to variables and methods which were deemed "safety critical" for software that was part of a control system. Couple this with the other rule about putting m_ on the front of member variables and you'd get something ridiculous like "s_m_blah()", which is darn annoying to write and not very readable in my opinion. In the end some 'safety expert' was supposed to gain insight by looking at the code and determining something from it by using those "s_" - in practice, they didn't know c++ too well so they couldn't do much other than make reports on the number of identifiers that we'd marked as 'safety critical'. Utter nonsense...

Since an ounce of experience is worth a ton of theory, I tried a little test program for MULTILINE
:
#define MULTILINE(...) #__VA_ARGS__
const char *mstr[] =
{
MULTILINE(1, 2, 3), // "1, 2, 3"
MULTILINE(1,2,3), // "1,2,3"
MULTILINE(1 , 2 , 3), // "1 , 2 , 3"
MULTILINE( 1 , 2 , 3 ), // "1 , 2 , 3"
MULTILINE((1, 2, 3)), // "(1, 2, 3)"
MULTILINE(1
2
3), // "1 2 3"
MULTILINE(1\n2\n3\n), // "1\n2\n3\n"
MULTILINE(1\n
2\n
3\n), // "1\n 2\n 3\n"
MULTILINE(1, "2" \3) // "1, \"2\" \3"
};
Compile this fragment with cpp -P -std=c++11 filename
to reproduce.
The trick behind #__VA_ARGS__
is that __VA_ARGS__
does not process the comma separator. So you can pass it to the stringizing operator. Leading and trailing spaces are trimmed, and spaces (including newlines) between words are compressed to a single space then. Parentheses need to be balanced. I think these shortcomings explain why the designers of C++11, despite #__VA_ARGS__
, saw the need for raw string literals.
It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.
In your case the variable can be declared like this:
<variable name="total" class="java.lang.Integer" calculation="Sum">
<variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>
The working example.

There are cases where you don't want to use v-model
. If you have two inputs, and each depend on each other, you might have circular referential issues. Common use cases is if you're building an accounting calculator.
In these cases, it's not a good idea to use either watchers or computed properties.
Instead, take your v-model
and split it as above answer indicates
<input
:value="something"
@input="something = $event.target.value"
>
In practice, if you are decoupling your logic this way, you'll probably be calling a method.
This is what it would look like in a real world scenario:
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>_x000D_
_x000D_
<div id="app">_x000D_
<input :value="extendedCost" @input="_onInputExtendedCost" />_x000D_
<p> {{ extendedCost }}_x000D_
</div>_x000D_
_x000D_
<script>_x000D_
var app = new Vue({_x000D_

You would use the read.csv
function; for example:
dat = read.csv("spam.csv", header = TRUE)
You can also reference this tutorial for more details.
Note: make sure the .csv
file to read is in your working directory (using getwd()
) or specify the right path to file. If you want, you can set the current directory using setwd
.
Maybe I misunderstand the question but if you want to convert the groupby back to a dataframe you can use .to_frame(). I wanted to reset the index when I did this so I included that part as well.
example code unrelated to question
df = df['TIME'].groupby(df['Name']).min()
df = df.to_frame()
df = df.reset_index(level=['Name',"TIME"])
I second Dipaks' answer, but often just the text-indent is enough as you may/maynot be positioning the ul for better layout control.

You are probably trying to create a foreign key in some table which exists with the same name in previously existing tables. Use the following format to name your foreign key
tablename_columnname_fk
Yes, it's possible, e.g. using the implicit conversion from RAW to BLOB:
insert into blob_fun values(1, hextoraw('453d7a34'));
453d7a34
is a string of hexadecimal values, which is first explicitly converted to the RAW data type and then inserted into the BLOB column. The result is a BLOB value of 4 bytes.
WMI is the best solution if the machine you are connecting to is a windows machine, but if you are looking at a linux, mac, or other type of network adapter, then you will need to use something else. Here are some options:
Heres a sample of item #3. This seems to be the best option if WMI isn't a viable solution:
using System.Runtime.InteropServices;
...
[DllImport("iphlpapi.dll", ExactSpelling = true)]
public static extern int SendARP(int DestIP, int SrcIP, byte[] pMacAddr, ref uint PhyAddrLen);
...
private string GetMacUsingARP(string IPAddr)
{
IPAddress IP = IPAddress.Parse(IPAddr);
byte[] macAddr = new byte[6];
uint macAddrLen = (uint)macAddr.Length;
if (SendARP((int)IP.Address, 0, macAddr, ref macAddrLen) != 0)
throw new Exception("ARP command failed");
string[] str = new string[(int)macAddrLen];
for (int i = 0; i < macAddrLen; i++)
str[i] = macAddr[i].ToString("x2");
return string.Join(":", str);
}
To give credit where it is due, this is the basis for that code: http://www.pinvoke.net/default.aspx/iphlpapi.sendarp#
You can't but you can do it anyway like this. I needed this for jQuery-File-Upload
import json
# get this object
from flask import Response
#example data:
js = [ { "name" : filename, "size" : st.st_size ,
"url" : url_for('show', filename=filename)} ]
#then do this
return Response(json.dumps(js), mimetype='application/json')
They are called the Positional Parameters.
3.4.1 Positional Parameters
A positional parameter is a parameter denoted by one or more digits, other than the single digit 0. Positional parameters are assigned from the shell’s arguments when it is invoked, and may be reassigned using the set builtin command. Positional parameter N may be referenced as ${N}, or as $N when N consists of a single digit. Positional parameters may not be assigned to with assignment statements. The set and shift builtins are used to set and unset them (see Shell Builtin Commands). The positional parameters are temporarily replaced when a shell function is executed (see Shell Functions).
When a positional parameter consisting of more than a single digit is expanded, it must be enclosed in braces.
//
syntaxregex.test(string)
, not string.test(regex)
So
jQuery(function () {
$(".mail").keyup(function () {
var VAL = this.value;
var email = new RegExp('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$');
if (email.test(VAL)) {
alert('Great, you entered an E-Mail-address');
}
});
});
Here is the working sample fiddle
Just remove additional \r\n and "|" from your reg ex.
The built-in getopts
can't do this. There is an external getopt(1) program that can do this, but you only get it on Linux from the util-linux package. It comes with an example script getopt-parse.bash.
There is also a getopts_long
written as a shell function.
parse_cols
is deprecated, use usecols
instead
that is:
df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")
You could do something this way:
$(document.body).find('*').each(function() {
if($(this).hasClass('lollypops')){ //class replacing..many ways to do this :)
$(this).removeClass('lollypops');
$(this).addClass('marshmellows');
}
var tmp = $(this).children().remove(); //removing and saving children to a tmp obj
var text = $(this).text(); //getting just current node text
text = text.replace(/lollypops/g, "marshmellows"); //replacing every lollypops occurence with marshmellows
$(this).text(text); //setting text
$(this).append(tmp); //re-append 'foundlings'
});

From your code, it looks like provider
is a variant or some other variable, and not an object.
Is Nothing
is for objects only, yet later you say it's a value that should either be NULL or NOT NULL, which would be handled by IsNull
.
Try using:
If Not IsNull(provider) Then
url = url & "&provider=" & provider
End if
Alternately, if that doesn't work, try:
If provider <> "" Then
url = url & "&provider=" & provider
End if
Here is another way of converting a xml to pandas data frame. For example i have parsing xml from a string but this logic holds good from reading file as well.
import pandas as pd
import xml.etree.ElementTree as ET
xml_str = '<?xml version="1.0" encoding="utf-8"?>\n<response>\n <head>\n <code>\n 200\n </code>\n </head>\n <body>\n <data id="0" name="All Categories" t="2018052600" tg="1" type="category"/>\n <data id="13" name="RealEstate.com.au [H]" t="2018052600" tg="1" type="publication"/>\n </body>\n</response>'
etree = ET.fromstring(xml_str)
dfcols = ['id', 'name']
df = pd.DataFrame(columns=dfcols)
for i in etree.iter(tag='data'):
df = df.append(
pd.Series([i.get('id'), i.get('name')], index=dfcols),
ignore_index=True)
df.head()
I had the same problem. I checked netstat, other processes running, firewall and changed httpd.conf, stopped antivirus, But all my efforts were in vain. :(
So finally the solution was to stop the IIS. And it worked :)
I guess IIS and apache cant work together. If anybody know any work around let us know.
You can try this:
Calendar sDate = Calendar.getInstance();
Calendar eDate = Calendar.getInstance();
sDate.setTime(startDate.getTime());
eDate.setTime(endDate.getTime());
int difInMonths = sDate.get(Calendar.MONTH) - eDate.get(Calendar.MONTH);
I think this should work. I used something similar for my project and it worked for what I needed (year diff). You get a Calendar
from a Date
and just get the month's diff.
Contrary to what cularis said there can be both in the parameter map.
The best way I see is to proxy the parameterMap and for each parameter retrieval check if queryString contains "&?<parameterName>=".
Note that parameterName needs to be URL encoded before this check can be made, as Qerub pointed out.
That saves you the parsing and still gives you only URL parameters.
The new
keyword is used in javascript to create a object from a constructor function. The new
keyword has to be placed before the constructor function call and will do the following things:
this
keyword to the newly created object and executes the constructor functionfunction Dog (age) {
this.age = age;
}
const doggie = new Dog(12);
console.log(doggie);
console.log(Object.getPrototypeOf(doggie) === Dog.prototype) // true
_x000D_
What exactly happens:
const doggie
says: We need memory for declaring a variable.=
says: We are going to initialize this variable with the expression after the =
new Dog(12)
. The JS engine sees the new keyword, creates a new object and sets the prototype to Dog.prototypethis
value set to the new object. In this step is where the age is assigned to the new created doggie object.Working with large models were very slow before the SP1, (have not tried it after the SP1, but it is said that is a snap now).
I still Design my tables first, then an in-house built tool generates the POCOs for me, so it takes the burden of doing repetitive tasks for each poco object.
when you are using source control systems, you can easily follow the history of your POCOs, it is not that easy with designer generated code.
I have a base for my POCO, which makes a lot of things quite easy.
I have views for all of my tables, each base view brings basic info for my foreign keys and my view POCOs derive from my POCO classes, which is quite usefull again.
And finally I dont like designers.
It is worth mentioning that there is also: database scoped global temporary tables(currently supported only by Azure SQL Database).
Global temporary tables for SQL Server (initiated with ## table name) are stored in tempdb and shared among all users’ sessions across the whole SQL Server instance.
Azure SQL Database supports global temporary tables that are also stored in tempdb and scoped to the database level. This means that global temporary tables are shared for all users’ sessions within the same Azure SQL Database. User sessions from other databases cannot access global temporary tables.
-- Session A creates a global temp table ##test in Azure SQL Database testdb1 -- and adds 1 row CREATE TABLE ##test ( a int, b int); INSERT INTO ##test values (1,1); -- Session B connects to Azure SQL Database testdb1 -- and can access table ##test created by session A SELECT * FROM ##test ---Results 1,1 -- Session C connects to another database in Azure SQL Database testdb2 -- and wants to access ##test created in testdb1. -- This select fails due to the database scope for the global temp tables SELECT * FROM ##test ---Results Msg 208, Level 16, State 0, Line 1 Invalid object name '##test'
ALTER DATABASE SCOPED CONFIGURATION
GLOBAL_TEMPORARY_TABLE_AUTODROP = { ON | OFF }
APPLIES TO: Azure SQL Database (feature is in public preview)
Allows setting the auto-drop functionality for global temporary tables. The default is ON, which means that the global temporary tables are automatically dropped when not in use by any session. When set to OFF, global temporary tables need to be explicitly dropped using a DROP TABLE statement or will be automatically dropped on server restart.
With Azure SQL Database single databases and elastic pools, this option can be set in the individual user databases of the SQL Database server. In SQL Server and Azure SQL Database managed instance, this option is set in TempDB and the setting of the individual user databases has no effect.
Even if the question is marked answered
, I would like to add some points
to it.
Set the DropDownStyle
property of the combobox to DropDownList
works for sure.
BUT what if the drop down list is longer, the user will have to scroll it to the desired item as he has no access to keyboard.
Private Sub cbostate_Validating(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles cbostate.Validating
If cbostate.SelectedValue Is Nothing AndAlso cbostate.Text <> String.Empty Then
e.Cancel = True
MsgBox("Invalid State")
End If
End Sub
I did it like this. I wanted to restrict the user entering 'random values' instead of 'state' but keeping he should be able to type and search states.
This validating event
occurs when the control loses focus
. So if user enters wrong value
in combobox
, It will not allow user
to do anything on the form, perhaps it will not even allow to change the focus from the combobox
If you are using this to get a LINQ to SQL which I do and wanted for my Visual Developer, 1) get the free Visual WEB Developer, use that to connect to SQL Server instance, create your LINQ interface, then copy the generated files into your Vis-Dev project (I don't use VD because it sounds funny). Include only the *.dbml files. The Vis-Dev environment will take a second or two to recognize the supporting files. It is a little extra step but for sure better than doing it by hand or giving up on it altogether or EVEN WORSE, paying for it. Mooo ha ha haha.

I know you are using Datepicker, but for some people who are just using HTML5 input date like me, there is an example how you can do the same: JSFiddle Link
$('#start_date').change(function(){
var start_date = $(this).val();
$('#end_date').prop({
min: start_date
});
});
/* prop() method works since jquery 1.6, if you are using a previus version, you can use attr() method.*/
java.util.Stack
inherits the synchronization overhead of java.util.Vector
, which is usually not justified.
It inherits a lot more than that, though. The fact that java.util.Stack extends java.util.Vector
is a mistake in object-oriented design. Purists will note that it also offers a lot of methods beyond the operations traditionally associated with a stack (namely: push, pop, peek, size). It's also possible to do search
, elementAt
, setElementAt
, remove
, and many other random-access operations. It's basically up to the user to refrain from using the non-stack operations of Stack
.
For these performance and OOP design reasons, the JavaDoc for java.util.Stack
recommends ArrayDeque
as the natural replacement. (A deque is more than a stack, but at least it's restricted to manipulating the two ends, rather than offering random access to everything.)
FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.
Some references:
Though you can use any other client that allows automation.
You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).
Combine WinSCP scripting capabilities with Windows Scheduler:
A typical WinSCP script for upload (with SFTP) looks like:
open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close
With FTP, just replace the sftp://
with the ftp://
and remove the -hostkey="..."
switch.
Similarly for download: How to schedule an automatic FTP download on Windows?
WinSCP can even generate a script from an imported FileZilla session.
For details, see the guide to FileZilla automation.
(I'm the author of WinSCP)
Another option, if you are using SFTP, is the psftp.exe
client from PuTTY suite.
In the first step, it will work fine as the value of a
will be 1 and that of b
will be 2 but as 2+1 will be returned and in the next step the value of b
will be the return value from step 1 i.e 3
and so b.x
will be undefined...and undefined + anyNumber will be NaN and that is why you are getting that result.
arr.reduce(function(a,b){return a + b.x},0);
I have read the many comments on this page that complain that using a dom parser is unnecessary overhead. Well, it may be more expensive than a mere regex call, but the OP has stated that there is no control over the order of the attributes in the img tags. This fact leads to unnecessary regex pattern convolution. Beyond that, using a dom parser provides the additional benefits of readability, maintainability, and dom-awareness (regex is not dom-aware).
I love regex and I answer lots of regex questions, but when dealing with valid HTML there is seldom a good reason to regex over a parser.
In the demonstration below, see how easy and clean DOMDocument handles img tag attributes in any order with a mixture of quoting (and no quoting at all). Also notice that tags without a targeted attribute are not disruptive at all -- an empty string is provided as a value.
Code: (Demo)
$test = <<<HTML
<img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny" />
<img src='/image/pricklycactus.jpg' title='Roger the cactus' alt='a big green prickly cactus' />
<p>This is irrelevant text.</p>
<img alt="an annoying white cockatoo" title="Polly the cockatoo" src="/image/noisycockatoo.jpg">
<img title=something src=somethingelse>
HTML;
libxml_use_internal_errors(true); // silences/forgives complaints from the parser (remove to see what is generated)
$dom = new DOMDocument();
$dom->loadHTML($test);
foreach ($dom->getElementsByTagName('img') as $i => $img) {
echo "IMG#{$i}:\n";
echo "\tsrc = " , $img->getAttribute('src') , "\n";
echo "\ttitle = " , $img->getAttribute('title') , "\n";
echo "\talt = " , $img->getAttribute('alt') , "\n";
echo "---\n";
}
Output:
IMG#0:
src = /image/fluffybunny.jpg
title = Harvey the bunny
alt = a cute little fluffy bunny
---
IMG#1:
src = /image/pricklycactus.jpg
title = Roger the cactus
alt = a big green prickly cactus

Using this technique in professional code will leave you with a clean script, fewer hiccups to contend with, and fewer colleagues that wish you worked somewhere else.
HTML/CSS Approach
If you are looking for an option that does not require much JavaScript (and and all the problems that come with it, such as rapid scroll event calls), it is possible to gain the same behavior by adding a wrapper <div>
and a couple of styles. I noticed much smoother scrolling (no elements lagging behind) when I used the following approach:
HTML
<div id="wrapper">
<div id="fixed">
[Fixed Content]
</div><!-- /fixed -->
<div id="scroller">
[Scrolling Content]
</div><!-- /scroller -->
</div><!-- /wrapper -->
CSS
#wrapper { position: relative; }
#fixed { position: fixed; top: 0; right: 0; }
#scroller { height: 100px; overflow: auto; }
JS
//Compensate for the scrollbar (otherwise #fixed will be positioned over it).
$(function() {
//Determine the difference in widths between
//the wrapper and the scroller. This value is
//the width of the scroll bar (if any).
var offset = $('#wrapper').width() - $('#scroller').get(0).clientWidth;
//Set the right offset
$('#fixed').css('right', offset + 'px');?
});
Of course, this approach could be modified for scrolling regions that gain/lose content during runtime (which would result in addition/removal of scrollbars).
You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -
, like script.ps1 -server http://devserver
Then you handle them in param
section in the beginning of the file.
You can also assign default values to your params, read them from console if not available or stop script execution:
param (
[string]$server = "http://defaultserver",
[Parameter(Mandatory=$true)][string]$username,
[string]$password = $( Read-Host "Input password, please" )
)
Inside the script you can simply
write-output $server
since all parameters become variables available in script scope.
In this example, the $server
gets a default value if the script is called without it, script stops if you omit the -username
parameter and asks for terminal input if -password
is omitted.
Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.
The keyword for that is [switch]
parameter type:
param (
[string]$server = "http://defaultserver",
[string]$password = $( Read-Host "Input password, please" ),
[switch]$force = $false
)
Inside the script then you would work with it like this:
if ($force) {
//deletes a file or does something "bad"
}
Now, when calling the script you'd set the switch/flag parameter like this:
.\yourscript.ps1 -server "http://otherserver" -force
If you explicitly want to state that the flag is not set, there is a special syntax for that
.\yourscript.ps1 -server "http://otherserver" -force:$false

Since many answers here explained well ::
behaviour, additionally I would like to clarify that ::
operator doesnt need to have exactly same signature as the referring Functional Interface if it is used for instance variables. Lets assume we need a BinaryOperator which has type of TestObject. In traditional way its implemented like this:
BinaryOperator<TestObject> binary = new BinaryOperator<TestObject>() {
@Override
public TestObject apply(TestObject t, TestObject u) {
return t;
}
};
As you see in anonymous implementation it requires two TestObject argument and returns a TestObject object as well. To satisfy this condition by using ::
operator we can start with a static method:
public class TestObject {
public static final TestObject testStatic(TestObject t, TestObject t2){
return t;
}
}
and then call:
BinaryOperator<TestObject> binary = TestObject::testStatic;
Ok it compiled fine. What about if we need an instance method? Lets update TestObject with instance method:
public class TestObject {
public final TestObject testInstance(TestObject t, TestObject t2){
return t;
}
public static final TestObject testStatic(TestObject t, TestObject t2){
return t;
}
}
Now we can access instance as below:
TestObject testObject = new TestObject();
BinaryOperator<TestObject> binary = testObject::testInstance;
This code compiles fine, but below one not:
BinaryOperator<TestObject> binary = TestObject::testInstance;
My eclipse tell me "Cannot make a static reference to the non-static method testInstance(TestObject, TestObject) from the type TestObject ..."
Fair enough its an instance method, but if we overload testInstance
as below:
public class TestObject {
public final TestObject testInstance(TestObject t){
return t;
}
public final TestObject testInstance(TestObject t, TestObject t2){
return t;
}
public static final TestObject testStatic(TestObject t, TestObject t2){
return t;
}
}
And call:
BinaryOperator<TestObject> binary = TestObject::testInstance;
The code will just compile fine. Because it will call testInstance
with single parameter instead of double one. Ok so what happened our two parameter? Lets printout and see:
public class TestObject {
public TestObject() {
System.out.println(this.hashCode());
}
public final TestObject testInstance(TestObject t){
System.out.println("Test instance called. this.hashCode:"
+ this.hashCode());
System.out.println("Given parameter hashCode:" + t.hashCode());
return t;
}
public final TestObject testInstance(TestObject t, TestObject t2){
return t;
}
public static final TestObject testStatic(TestObject t, TestObject t2){
return t;
}
}
Which will output:
1418481495
303563356
Test instance called. this.hashCode:1418481495
Given parameter hashCode:303563356
Ok so JVM is smart enough to call param1.testInstance(param2). Can we use testInstance
from another resource but not TestObject, i.e.:
public class TestUtil {
public final TestObject testInstance(TestObject t){
return t;
}
}
And call:
BinaryOperator<TestObject> binary = TestUtil::testInstance;
It will just not compile and compiler will tell: "The type TestUtil does not define testInstance(TestObject, TestObject)". So compiler will look for a static reference if it is not the same type. Ok what about polymorphism? If we remove final modifiers and add our SubTestObject class:
public class SubTestObject extends TestObject {
public final TestObject testInstance(TestObject t){
return t;
}
}
And call:
BinaryOperator<TestObject> binary = SubTestObject::testInstance;
It will not compile as well, compiler will still look for static reference. But below code will compile fine since it is passing is-a test:
public class TestObject {
public SubTestObject testInstance(Object t){
return (SubTestObject) t;
}
}
BinaryOperator<TestObject> binary = TestObject::testInstance;

Here is a complete example that has been tested with Python 2.7.5 on CentOS 7.
#!/usr/bin/python
import sys, socket
def main(args):
ip = args[1]
port = int(args[2])
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
file = 'sample.csv'
fp = open(file, 'r')
for line in fp:
sock.sendto(line.encode('utf-8'), (ip, port))
fp.close()
main(sys.argv)
The program reads a file, sample.csv
from the current directory and sends each line in a separate UDP packet. If the program it were saved in a file named send-udp
then one could run it by doing something like:
$ python send-udp 192.168.1.2 30088
You can use .replace
. For example:
>>> df = pd.DataFrame({'col2': {0: 'a', 1: 2, 2: np.nan}, 'col1': {0: 'w', 1: 1, 2: 2}})
>>> di = {1: "A", 2: "B"}
>>> df
col1 col2
0 w a
1 1 2
2 2 NaN
>>> df.replace({"col1": di})
col1 col2
0 w a
1 A 2
2 B NaN
or directly on the Series
, i.e. df["col1"].replace(di, inplace=True)
.

I"m guessing i'm getting this error because the string is trying to substring a Null value. But wouldn't the ".length() > 0" part eliminate that issue?
No, calling itemdescription.length() when itemdescription is null would not generate a StringIndexOutOfBoundsException, but rather a NullPointerException since you would essentially be trying to call a method on null.
As others have indicated, StringIndexOutOfBoundsException indicates that itemdescription is not at least 38 characters long. You probably want to handle both conditions (I assuming you want to truncate):
final String value;
if (itemdescription == null || itemdescription.length() <= 0) {
value = "_";
} else if (itemdescription.length() <= 38) {
value = itemdescription;
} else {
value = itemdescription.substring(0, 38);
}
pstmt2.setString(3, value);
Might be a good place for a utility function if you do that a lot...
In REST, each HTTP verbs has its place and meaning.
For example,
GET is to get the 'resource(s)' that is pointed to in the URL.
POST is to instructure the backend to 'create' a resource of the 'type' pointed to in the URL. You can supplement the POST operation with parameters or additional data in the body of the POST call.
In you case, since you are interested in 'getting' the info using query, thus it should be a GET operation instead of a POST operation.
This wiki may help to further clarify things.
Hope this help!

Mirko Froehlich's answer worked for me, except when i wanted to use custom colors. The trick is to specify UI color with Hue, saturation and brightness instead of RGB.
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = myView.bounds;
UIColor *startColour = [UIColor colorWithHue:.580555 saturation:0.31 brightness:0.90 alpha:1.0];
UIColor *endColour = [UIColor colorWithHue:.58333 saturation:0.50 brightness:0.62 alpha:1.0];
gradient.colors = [NSArray arrayWithObjects:(id)[startColour CGColor], (id)[endColour CGColor], nil];
[myView.layer insertSublayer:gradient atIndex:0];
To get the Hue, Saturation and Brightness of a color, use the in built xcode color picker and go to the HSB tab. Hue is measured in degrees in this view, so divide the value by 360 to get the value you will want to enter in code.

I had similar issue where i had to save the contents of the dataframe to a csv file of name which i defined. df.write("csv").save("<my-path>")
was creating directory than file. So have to come up with the following solutions.
Most of the code is taken from the following dataframe-to-csv with little modifications to the logic.
def saveDfToCsv(df: DataFrame, tsvOutput: String, sep: String = ",", header: Boolean = false): Unit = {
val tmpParquetDir = "Posts.tmp.parquet"
df.repartition(1).write.
format("com.databricks.spark.csv").
option("header", header.toString).
option("delimiter", sep).
save(tmpParquetDir)
val dir = new File(tmpParquetDir)
val newFileRgex = tmpParquetDir + File.separatorChar + ".part-00000.*.csv"
val tmpTsfFile = dir.listFiles.filter(_.toPath.toString.matches(newFileRgex))(0).toString
(new File(tmpTsvFile)).renameTo(new File(tsvOutput))
dir.listFiles.foreach( f => f.delete )
dir.delete
}

DELETE DUP
FROM
(
SELECT ROW_NUMBER() OVER (PARTITION BY Clientid ORDER BY Clientid ) AS Val
FROM ClientMaster
) DUP
WHERE DUP.Val > 1
Explanation
Use an inner query to construct a view over the table which includes a field based on Row_Number()
, partitioned by those columns you wish to be unique.
Delete from the results of this inner query, selecting anything which does not have a row number of 1; i.e. the duplicates; not the original.
The order by
clause of the row_number window function is needed for a valid syntax; you can put any column name here. If you wish to change which of the results is treated as a duplicate (e.g. keep the earliest or most recent, etc), then the column(s) used here do matter; i.e. you want to specify the order such that the record you wish to keep will come first in the result.
Three ways based on the same simple instruction:
a). Results as easy as locate (1):
android:focusableInTouchMode="true"
among the configuration of any precedent element in the layout, example:
if your whole layout is composed of:
<ImageView>
<EditTextView>
<EditTextView>
<EditTextView>
then you can write the (1) among ImageView parameters and this will grab android's attention to the ImageView instead of the EditText.
b). In case you have another precedent element than an ImageView you may need to add (2) to (1) as:
android:focusable="true"
c). you can also simply create an empty element at the top of your view elements:
<LinearLayout
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="0px"
android:layout_height="0px" />
This alternative until this point results as the simplest of all I've seen. Hope it helps...
Download Git on Msys. Then:

The documentation for the Python 3 CSV module provides this example:
with open('example.csv', newline='') as csvfile:
dialect = csv.Sniffer().sniff(csvfile.read(1024))
csvfile.seek(0)
reader = csv.reader(csvfile, dialect)
# ... process CSV file contents here ...
The Sniffer
will try to auto-detect many things about the CSV file. You need to explicitly call its has_header()
method to determine whether the file has a header line. If it does, then skip the first row when iterating the CSV rows. You can do it like this:
if sniffer.has_header():
for header_row in reader:
break
for data_row in reader:
# do something with the row
Similar to above, using filter
from dplyr
:
filter(df, fct %in% vc)
You almost never want to use Read Uncommited
since it's not really ACID
compliant. Read Commmited
is a good default starting place. Repeatable Read
is probably only needed in reporting, rollup or aggregation scenarios. Note that many DBs, postgres included don't actually support Repeatable Read, you have to use Serializable
instead. Serializable
is useful for things that you know have to happen completely independently of anything else; think of it like synchronized
in Java. Serializable goes hand in hand with REQUIRES_NEW
propagation.
I use REQUIRES
for all functions that run UPDATE or DELETE queries as well as "service" level functions. For DAO level functions that only run SELECTs, I use SUPPORTS
which will participate in a TX if one is already started (i.e. being called from a service function).

this is a sample database with an integrated test suite, used to test your applications and database servers
According to launchpad.net the database has moved to github.
The database contains about 300,000 employee records with 2.8 million salary entries. The export data is 167 MB, which is not huge, but heavy enough to be non-trivial for testing.
The data was generated, and as such there are inconsistencies and subtle problems. Rather than removing them, we decided to leave the contents untouched, and use these issues as data cleaning exercises.
Here I am providing a negative example where your want to avoid when converting floating number to strings.
float num=99.463;
float tmp1=round(num*1000);
float tmp2=tmp1/1000;
cout << tmp1 << " " << tmp2 << " " << to_string(tmp2) << endl;
You get
99463 99.463 99.462997
Note: the num variable can be any value close to 99.463, you will get the same print out. The point is to avoid the convenient c++11 "to_string" function. It took me a while to get out this trap. The best way is the stringstream and sprintf methods (C language). C++11 or newer should provided a second parameter as the number of digits after the floating point to show. Right now the default is 6. I am positing this so that others won't wast time on this subject.
I wrote my first version, please let me know if you find any bug that needs to be fixed. You can control the exact behavior with the iomanipulator. My function is for showing the number of digits after the decimal point.
string ftos(float f, int nd) {
ostringstream ostr;
int tens = stoi("1" + string(nd, '0'));
ostr << round(f*tens)/tens;
return ostr.str();
}
Please search the site before asking questions next time: how to concatenate two dictionaries to create a new one in Python?
The easiest way to do it is to simply use your example code, but using the items() member of each dictionary. So, the code would be:
dic0 = {'dic0': 0}
dic1 = {'dic1': 1}
dic2 = dict(dic0.items() + dic1.items())
I tested this in IDLE and it works fine. However, the previous question on this topic states that this method is slow and chews up memory. There are several other ways recommended there, so please see that if memory usage is important.
#for python 3
A = [0,1,2,3,4,5]
l = len(A)/2
B = A[:int(l)]
C = A[int(l):]
Ensure that Enhanced session mode settings are enabled on the Hyper-V host.
Start Hyper-V Manager, and in the Actions section, select "Hyper-V Settings".
Make sure that enhanced session mode is allowed in the Server section. Then, make sure that the enhanced session mode is available in the User section.
Enable Hyper-V Guest Services for your virtual machine
Right-click on Virtual Machine > Settings. Select the Integration Services in the left-lower corner of the menu. Check Guest Service and click OK.
Start a virtual machine and click Show Options in the pop-up windows.
Or click "Edit Session Settings..." in the Actions panel on the right
It may only appear when you're (able to get) connected to it. If it doesn't appear try Starting and then Connecting to the VM while paying close attention to the panel in the Hyper-V Manager.
View local resources. Then, select the "More..." menu.
From there, you can choose which devices to share. Removable drives are especially useful for file sharing.
Choose to "Save my settings for future connections to this virtual machine".
Click Connect. Drive sharing is now complete, and you will see the shared drive in this PC > Network Locations section of Windows Explorer after using the enhanced session mode to sigh to the VM. You should now be able to copy files from a physical machine and paste them into a virtual machine, and vice versa.

I bumped into this too and found a solution.
First on how I got into this problem. I have a project which builds in x86. Then I used the Configuration Manager to add x64, and I hit this problem.
By looking at BuildLog.htm
carefully, I saw both of these listed as linker options:
/MACHINE:X64
/machine:X86
I could not find anywhere in the Property Pages dialog where I could change this, so I opened up the .vcproj
file and looked for the appropriate line and changed it to:
AdditionalOptions=" /STACK:10000000 /machine:x64 /debug"
and problem solved.
A simple jquery solution for those who don't need a pure css solution:
$(".letter").hover(function() {_x000D_
$(this).closest("#word").toggleClass("hovered")_x000D_
});
_x000D_
.hovered {_x000D_
background-color: lightblue;_x000D_
}_x000D_
_x000D_
.letter {_x000D_
margin: 20px;_x000D_
background: lightgray;_x000D_
}_x000D_

Use either of the Map
implementations bundled with Java 6 and later that implement NavigableMap
(the successor to SortedMap
):
TreeMap
if running single-threaded, or if the map is to be read-only across threads after first being populated. ConcurrentSkipListMap
if manipulating the map across threads.NavigableMap
FYI, the SortedMap
interface was succeeded by the NavigableMap
interface.
You would only need to use SortedMap
if using 3rd-party implementations that have not yet declared their support of NavigableMap
. Of the maps bundled with Java, both of the implementations that implement SortedMap
also implement NavigableMap
.
s SortedMap the best answer? TreeMap?
As others mentioned, SortedMap
is an interface while TreeMap
is one of multiple implementations of that interface (and of the more recent NavigableMap
.
Having an interface allows you to write code that uses the map without breaking if you later decide to switch between implementations.
NavigableMap< Employee , Project > currentAssignments = new TreeSet<>() ;
currentAssignments.put( alice , writeAdCopyProject ) ;
currentAssignments.put( bob , setUpNewVendorsProject ) ;
This code still works if later change implementations. Perhaps you later need a map that supports concurrency for use across threads. Change that declaration to:
NavigableMap< Employee , Project > currentAssignments = new ConcurrentSkipListMap<>() ;
…and the rest of your code using that map continues to work.
There are ten implementations of Map
bundled with Java 11. And more implementations provided by 3rd parties such as Google Guava.
Here is a graphic table I made highlighting the various features of each. Notice that two of the bundled implementations keep the keys in sorted order by examining the key’s content. Also, EnumMap
keeps its keys in the order of the objects defined on that enum. Lastly, the LinkedHashMap
remembers original insertion order.
The ready event is always execute at the only html page is loaded to the browser and the functions are executed.... But the load event is executed at the time of all the page contents are loaded to the browser for the page..... we can use $ or jQuery when we use the noconflict() method in jquery scripts...
7 years old post, but I was not able to understand top few posts, because they are complex. So, I wrote my own solution:
function strEndsWith(str, endwith)
{
var lastIndex = url.lastIndexOf(endsWith);
var result = false;
if (lastIndex > 0 && (lastIndex + "registerc".length) == url.length)
{
result = true;
}
return result;
}
var testArray = ['a','b','c','d','d','e','a','b','c','f','g','h','h','h','e','a'];
var newArr = [];
testArray.forEach((item) => {
newArr[item] = testArray.filter((el) => {
return el === item;
}).length;
})
console.log(newArr);
Concatenating strings in awk can be accomplished by the print command AWK manual page, and you can do complicated combination. Here I was trying to change the 16 char to A and used string concatenation:
echo CTCTCTGAAATCACTGAGCAGGAGAAAGATT | awk -v w=15 -v BA=A '{OFS=""; print substr($0, 1, w), BA, substr($0,w+2)}'
Output: CTCTCTGAAATCACTAAGCAGGAGAAAGATT
I used the substr function to extract a portion of the input (STDIN). I passed some external parameters (here I am using hard-coded values) that are usually shell variable. In the context of shell programming, you can write -v w=$width -v BA=$my_charval. The key is the OFS which stands for Output Field Separate in awk. Print function take a list of values and write them to the STDOUT and glue them with the OFS. This is analogous to the perl join function.
It looks that in awk, string can be concatenated by printing variable next to each other:
echo xxx | awk -v a="aaa" -v b="bbb" '{ print a b $1 "string literal"}'
# will produce: aaabbbxxxstring literal
Just use
int listCount = data.size();
That tells you how many lists there are (assuming none are null). If you want to find out how many strings there are, you'll need to iterate:
int total = 0;
for (List<String> sublist : data) {
// TODO: Null checking
total += sublist.size();
}
// total is now the total number of strings
Stumbled across this today in a search for answers and I thought I'd add my version to the list (No pun intended). It utlises the null conditional operator of c#6.0
IEnumerable<Item> collection = GetTheCollection();
var index = collection
.Select((item,idx) => new { Item = item, Index = idx })
//or .FirstOrDefault(_ => _.Item.Prop == something)
.FirstOrDefault(_ => _.Item == itemToFind)?.Index ?? -1;
I've done some 'racing of the old horses' (testing) and for large collections (~100,000), worst case scenario that item you want is at the end, this is 2x faster than doing ToList().FindIndex()
. If the Item you want is in the middle its ~4x faster.
For smaller collections (~10,000) it seems to be only marginally faster
Heres how I tested it https://gist.github.com/insulind/16310945247fcf13ba186a45734f254e
I recommend you to use an unordered list for your image gallery.
You should use my code unless you want the image to gain instantly 50% opacity after you hover out. You will have a smoother transition.
#photos li {
opacity: .5;
transition: opacity .5s ease-out;
-moz-transition: opacity .5s ease-out;
-webkit-transition: opacity .5s ease-out;
-o-transition: opacity .5s ease-out;
}
#photos li:hover {
opacity: 1;
}
if you want to call click event:
SomeButton.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));
And if you want the button looks like it is pressed:
typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(SomeButton, new object[] { true });
and unpressed after that:
typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(SomeButton, new object[] { false });
or use the ToggleButton
This also works:
this.getCurrentFocus()
It gets the view so I can use it.
This works for me (Ubuntu 13.10 Desktop to an Ubuntu 14.04 Server) :-
sudo umount -f /mnt/my_share
Mounted with
sudo mount -t cifs -o username=me,password=mine //192.168.0.111/serv_share /mnt/my_share
where serv_share is that set up and pointed to in the smb.conf file.
Check out the language reference:

Both of these classes are smart pointers, which means that they automatically (in most cases) will deallocate the object that they point at when that object can no longer be referenced. The difference between the two is how many different pointers of each type can refer to a resource.
When using unique_ptr
, there can be at most one unique_ptr
pointing at any one resource. When that unique_ptr
is destroyed, the resource is automatically reclaimed. Because there can only be one unique_ptr
to any resource, any attempt to make a copy of a unique_ptr
will cause a compile-time error. For example, this code is illegal:
unique_ptr<T> myPtr(new T); // Okay
unique_ptr<T> myOtherPtr = myPtr; // Error: Can't copy unique_ptr
However, unique_ptr
can be moved using the new move semantics:
unique_ptr<T> myPtr(new T); // Okay
unique_ptr<T> myOtherPtr = std::move(myPtr); // Okay, resource now stored in myOtherPtr
Similarly, you can do something like this:
unique_ptr<T> MyFunction() {
unique_ptr<T> myPtr(/* ... */);
/* ... */
return myPtr;
}
This idiom means "I'm returning a managed resource to you. If you don't explicitly capture the return value, then the resource will be cleaned up. If you do, then you now have exclusive ownership of that resource." In this way, you can think of unique_ptr
as a safer, better replacement for auto_ptr
.
shared_ptr
, on the other hand, allows for multiple pointers to point at a given resource. When the very last shared_ptr
to a resource is destroyed, the resource will be deallocated. For example, this code is perfectly legal:
shared_ptr<T> myPtr(new T); // Okay
shared_ptr<T> myOtherPtr = myPtr; // Sure! Now have two pointers to the resource.
Internally, shared_ptr
uses reference counting to track how many pointers refer to a resource, so you need to be careful not to introduce any reference cycles.
In short:
unique_ptr
when you want a single pointer to an object that will be reclaimed when that single pointer is destroyed.shared_ptr
when you want multiple pointers to the same resource.Hope this helps!
Five problems:
"$(...)"
to get the output of a command as text.[
is a command. Put a space between it and the arguments.echo
.rm "$folderToBeMoved"
Pseudo code, something like:
CASE
When CHARINDEX('lactulose', dbo.Table.Column) > 0 Then 'BP Medication'
ELSE ''
END AS 'Medication Type'
This does not care where the keyword is found in the list and avoids depending on formatting of spaces and commas.
Type the kill -l command on your shell
you will found that at 9th number [ 9) SIGKILL ], so one can use either kill -9 or kill -SIGKILL
SIGKILL is sure kill signal, It can not be dis-positioned, ignore or handle. It always work with its default behaviour, which is to kill the process.
This might be useful:
objectMapper.writeValue(new File("c:\\employee.json"), employee);
// display to console
Object json = objectMapper.readValue(
objectMapper.writeValueAsString(employee), Object.class);
System.out.println(objectMapper.writerWithDefaultPrettyPrinter()
.writeValueAsString(json));
var bordT = $('img').outerWidth() - $('img').innerWidth();
var paddT = $('img').innerWidth() - $('img').width();
var margT = $('img').outerWidth(true) - $('img').outerWidth();
var formattedBord = bordT + 'px';
var formattedPadd = paddT + 'px';
var formattedMarg = margT + 'px';
Check the jQuery API docs for information on each:
Here's the edited jsFiddle showing the result.
You can perform the same type of operations for the Height to get its margin, border, and padding.
window.open($('#myanchor').attr('href'));
$('#myanchor')[0].click();
The easiest might be:
Array(1, 2, 3) :+ 4
Actually, Array can be implcitly transformed in a WrappedArray
You don't need to have static

If you want to set required to true
$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',true);
});
if you want to set required to false
$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',false);
});
I think there could be no form elements by name 'month' or 'op'. Can you verify if the HTML source (of the page which results in error when submitted) indeed has html elements by he above names
I had the same issue but in this case microsoft-ace-oledb-12-0-provider was already installed on my machine and working fine for other application developed.
The difference between those application and the one with I had the problem was the Old Applications were running on "Local IIS" whereas the one with error was on "IIS Express(running from Visual Studio"). So what I did was-
- Right Click on Project Name.
- Go to Properties
- Go to Web Tab on the right.
- Under Servers select Local IIS and click on Create Virtual Directory button.
- Run the application again and it worked.
For anyone who found out that best answer don't work.
Try to use:
$( "#aioConceptName option:selected" ).attr("value");
Works for me in recent projects so it is worth to look on it.
When we first moved over to Vista with Oracle 10g, we experienced this issue when we installed the Oracle client on our Vista boxes, even when we were running with admin privileges during install.
Oracle brought out a new version of the 10g client (10.2.0.3) that was Vista compatible.
I do believe that this was after 11g was released, so it is possible that there is a 'Vista compatible' version for 11g also.
i agree with alf's answer,but little modification to it is,, to use,
try
{
control_name.Click -= event_Click;
main_browser.Document.Click += Document_Click;
}
catch(Exception exce)
{
main_browser.Document.Click += Document_Click;
}
If you want to allow the user to browse for a file, you need to have an input type="file"
The closest you could get to your requirement would be to place the input type="file"
on the page and hide it. Then, trigger the click event of the input when the button is clicked:
#myFileInput {
display:none;
}
<input type="file" id="myFileInput" />
<input type="button"
onclick="document.getElementById('myFileInput').click()"
value="Select a File" />
Here's a working fiddle.
Note: I would not recommend this approach. The input type="file"
is the mechanism that users are accustomed to using for uploading a file.
It says already we are running the services with port no 4200 please use another port instead of 4200. Below command is to solve the problem
ng serve --port 4300
This is an example of one way of writing an extension method (note: I wouldn't use this for very large arrays; another data structure would be more appropriate...):
namespace StringExtensionMethods
{
public static class StringExtension
{
public static bool Contains(this string[] stringarray, string pat)
{
bool result = false;
foreach (string s in stringarray)
{
if (s == pat)
{
result = true;
break;
}
}
return result;
}
}
}
Your code is OK. Note though that if you return a pointer to an array, and that array goes out of scope, you should not use that pointer anymore. Example:
int* test (void)
{
int out[5];
return out;
}
The above will never work, because out
does not exist anymore when test()
returns. The returned pointer must not be used anymore. If you do use it, you will be reading/writing to memory you shouldn't.
In your original code, the arr
array goes out of scope when main()
returns. Obviously that's no problem, since returning from main()
also means that your program is terminating.
If you want something that will stick around and cannot go out of scope, you should allocate it with new
:
int* test (void)
{
int* out = new int[5];
return out;
}
The returned pointer will always be valid. Remember do delete it again when you're done with it though, using delete[]
:
int* array = test();
// ...
// Done with the array.
delete[] array;
Deleting it is the only way to reclaim the memory it uses.
First, you have to download a font type...for example: https://www.wfonts.com/font/microsoft-sans-serif.
After that, use this code to draw the text:
from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw
img = Image.open("filename.jpg")
draw = ImageDraw.Draw(img)
font = ImageFont.truetype(r'filepath\..\sans-serif.ttf', 16)
draw.text((0, 0),"Draw This Text",(0,0,0),font=font) # this will draw text with Blackcolor and 16 size
img.save('sample-out.jpg')
This is iteration using block approach:
NSDictionary *dict = @{@"key1":@1, @"key2":@2, @"key3":@3};
[dict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
NSLog(@"%@->%@",key,obj);
// Set stop to YES when you wanted to break the iteration.
}];
With autocompletion is very fast to set, and you do not have to worry about writing iteration envelope.
Never construct BigDecimals from floats or doubles. Construct them from ints or strings. floats and doubles loose precision.
This code works as expected (I just changed the type from double to String):
public static void main(String[] args) {
String doubleVal = "1.745";
String doubleVal1 = "0.745";
BigDecimal bdTest = new BigDecimal( doubleVal);
BigDecimal bdTest1 = new BigDecimal( doubleVal1 );
bdTest = bdTest.setScale(2, BigDecimal.ROUND_HALF_UP);
bdTest1 = bdTest1.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("bdTest:"+bdTest); //1.75
System.out.println("bdTest1:"+bdTest1);//0.75, no problem
}
For me what works here is to using a version manager such as pyenv, which I strongly recommend to get your project environments and package versions well managed and separate from that of the operative system.
I had this same error after an OS update, but was easily fixed with pyenv install 3.7-dev
(the version I use).
If you truly want to discard the commits you've made locally, i.e. never have them in the history again, you're not asking how to pull - pull means merge, and you don't need to merge. All you need do is this:
# fetch from the default remote, origin
git fetch
# reset your current branch (master) to origin's master
git reset --hard origin/master
I'd personally recommend creating a backup branch at your current HEAD first, so that if you realize this was a bad idea, you haven't lost track of it.
If on the other hand, you want to keep those commits and make it look as though you merged with origin, and cause the merge to keep the versions from origin only, you can use the ours
merge strategy:
# fetch from the default remote, origin
git fetch
# create a branch at your current master
git branch old-master
# reset to origin's master
git reset --hard origin/master
# merge your old master, keeping "our" (origin/master's) content
git merge -s ours old-master
MySQL recently changed they way they store the DECIMAL type. In the past they stored the characters (or nybbles) for each digit comprising an ASCII (or nybble) representation of a number - vs - a two's complement integer, or some derivative thereof.
The current storage format for DECIMAL is a series of 1,2,3,or 4-byte integers whose bits are concatenated to create a two's complement number with an implied decimal point, defined by you, and stored in the DB schema when you declare the column and specify it's DECIMAL size and decimal point position.
By way of example, if you take a 32-bit int you can store any number from 0 - 4,294,967,295. That will only reliably cover 999,999,999, so if you threw out 2 bits and used (1<<30 -1) you'd give up nothing. Covering all 9-digit numbers with only 4 bytes is more efficient than covering 4 digits in 32 bits using 4 ASCII characters, or 8 nybble digits. (a nybble is 4-bits, allowing values 0-15, more than is needed for 0-9, but you can't eliminate that waste by going to 3 bits, because that only covers values 0-7)
The example used on the MySQL online docs uses DECIMAL(18,9) as an example. This is 9 digits ahead of and 9 digits behind the implied decimal point, which as explained above requires the following storage.
As 18 8-bit chars: 144 bits
As 18 4-bit nybbles: 72 bits
As 2 32-bit integers: 64 bits
Currently DECIMAL supports a max of 65 digits, as DECIMAL(M,D) where the largest value for M allowed is 65, and the largest value of D allowed is 30.
So as not to require chunks of 9 digits at a time, integers smaller than 32-bits are used to add digits using 1,2 and 3 byte integers. For some reason that defies logic, signed, instead of unsigned ints were used, and in so doing, 1 bit gets thrown out, resulting in the following storage capabilities. For 1,2 and 4 byte ints the lost bit doesn't matter, but for the 3-byte int it's a disaster because an entire digit is lost due to the loss of that single bit.
With an 7-bit int: 0 - 99
With a 15-bit int: 0 - 9,999
With a 23-bit int: 0 - 999,999 (0 - 9,999,999 with a 24-bit int)
1,2,3 and 4-byte integers are concatenated together to form a "bit pool" DECIMAL uses to represent the number precisely as a two's complement integer. The decimal point is NOT stored, it is implied.
This means that no ASCII to int conversions are required of the DB engine to convert the "number" into something the CPU recognizes as a number. No rounding, no conversion errors, it's a real number the CPU can manipulate.
Calculations on this arbitrarily large integer must be done in software, as there is no hardware support for this kind of number, but these libraries are very old and highly optimized, having been written 50 years ago to support IBM 370 Fortran arbitrary precision floating point data. They're still a lot slower than fixed-sized integer algebra done with CPU integer hardware, or floating point calculations done on the FPU.
In terms of storage efficiency, because the exponent of a float is attached to each and every float, specifying implicitly where the decimal point is, it is massively redundant, and therefore inefficient for DB work. In a DB you already know where the decimal point is to go up front, and every row in the table that has a value for a DECIMAL column need only look at the 1 & only specification of where that decimal point is to be placed, stored in the schema as the arguments to a DECIMAL(M,D) as the implication of the M and the D values.
The many remarks found here about which format is to be used for various kinds of applications are correct, so I won't belabor the point. I took the time to write this here because whoever is maintaining the linked MySQL online documentation doesn't understand any of the above and after rounds of increasingly frustrating attempts to explain it to them I gave up. A good indication of how poorly they understood what they were writing is the very muddled and almost indecipherable presentation of the subject matter.
As a final thought, if you have need of high-precision floating point computation, there've been tremendous advances in floating point code in the last 20 years, and hardware support for 96-bit and Quadruple Precision float are right around the corner, but there are good arbitrary precision libraries out there if manipulation of the stored value is important.
In Swift 2 you can do it in this way:
var dictionary: NSDictionary = ...
/* NSDictionary to NSData */
let data = NSKeyedArchiver.archivedDataWithRootObject(dictionary)
/* NSData to NSDictionary */
let unarchivedDictionary = NSKeyedUnarchiver.unarchiveObjectWithData(data!) as! NSDictionary
In Swift 3:
/* NSDictionary to NSData */
let data = NSKeyedArchiver.archivedData(withRootObject: dictionary)
/* NSData to NSDictionary */
let unarchivedDictionary = NSKeyedUnarchiver.unarchiveObject(with: data)
It's better to try to simulate a webbrowser by yourself.You don't have to stick with Chrome or IE or else thing.
If you're using Python,you can try package pyQt4 which helps you to simulate a webbrowser. By doing this,there will not be any security reasons and you can set the webbrowser to show in full screen mode automatically.
In Xcode 6.1.1
extension String {
var length : Int { return self.utf16Count }
}
I think that brainiacs will change this on every minor version.
I know this is question is a year old, but here's some pretty simple code (mostly from this tutorial) that's working well for me:
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet weak var imageView: UIImageView!
var imagePicker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
self.imagePicker.delegate = self
}
@IBAction func loadImageButtonTapped(sender: AnyObject) {
print("hey!")
self.imagePicker.allowsEditing = false
self.imagePicker.sourceType = .SavedPhotosAlbum
self.presentViewController(imagePicker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
self.imageView.contentMode = .ScaleAspectFit
self.imageView.image = pickedImage
}
dismissViewControllerAnimated(true, completion: nil)
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
self.imagePicker = UIImagePickerController()
dismissViewControllerAnimated(true, completion: nil)
}

My keyboard is a Latin Apple MacBook Pro, which is called Spanish - ISO. I tried the changing keyboard distribution to U.S. solution... this works but with this solution I have to switch keyboards every time I want to comment which... sucks.
So I tried ctrl
+ -
and it works. The -
is where the /
is located in an english keyboard but doing Cmd
+ -
only changes the Chrome's zoom so I tried Ctrl which isn't as used as Cmd in macOS.
My takeaway with this would be: if I have more shortcut problems I might try the original shortcut but using the key where the U.S. keyboard would have it.
In VueJS you can loop through an array like this : const array1 = ['a', 'b', 'c'];
Array.from(array1).forEach(element =>
console.log(element)
);
in my case I want to loop through files and add their types to another array:
Array.from(files).forEach((file) => {
if(this.mediaTypes.image.includes(file.type)) {
this.media.images.push(file)
console.log(this.media.images)
}
}
You want:
dir > a.txt 2>&1
The syntax 2>&1
will redirect 2
(stderr) to 1
(stdout). You can also hide messages by redirecting to NUL
, more explanation and examples on MSDN.
You can use the:
setBackgroundDrawable(null);
method.And following is the doc:
/**
* Set the background to a given Drawable, or remove the background. If the
* background has padding, this View's padding is set to the background's
* padding. However, when a background is removed, this View's padding isn't
* touched. If setting the padding is desired, please use
* {@link #setPadding(int, int, int, int)}.
*
* @param d The Drawable to use as the background, or null to remove the
* background
*/
Can't change the default browser, but try this (found online a while ago). Add a bookmark in Safari called "Open in Chrome" with the following.
javascript:location.href=%22googlechrome%22+location.href.substring(4);
Will open the current page in Chrome. Not as convenient, but maybe someone will find it useful.
Works for me.
treeViewMain.SelectedNode = treeViewMain.Nodes.Find(searchNode, true)[0];
where searchNode is the name of the node. I'm personally using a combo "Node + Panel" where Node name is Node + and the same tag is also set on panel of choice. With this command + scan of panels by tag i'm usually able to work a treeview+panel full menu set.
You need to use the reserve function to set an initial allocated size or do it in the initial constructor.
vector<CustomClass *> content(20000);
or
vector<CustomClass *> content;
...
content.reserve(20000);
When you reserve()
elements, the vector
will allocate enough space for (at least?) that many elements. The elements do not exist in the vector
, but the memory is ready to be used. This will then possibly speed up push_back()
because the memory is already allocated.
I changed a couple of pngs and the build number in the gradle and now I get this. No amount of cleaning and restarting helped. Disabling Instant Run fixed it for me. YMMV
I struggled for days. I tried all the different configurations suggested in this thread. None of them works. Finally, I find only the important configuration is the prepare-agent goal. But you have to put it in the right phase. I saw so many examples put it in the "pre-integration-test", that's a misleading, as it will only be executed after unit test. So the unit test won't be instrumented.
The right config should just use the default phase, (don't specify the phase explicitly). And usually, you don't need to mass around maven-surefire-plugin.

Htmlparser2 by FB55 seems to be a good alternative.
another nice recursive way to generate HTML from a nested JSON object (currently not supporting arrays):
// generate HTML code for an object
var make_table = function(json, css_class='tbl_calss', tabs=1){
// helper to tabulate the HTML tags. will return '\t\t\t' for num_of_tabs=3
var tab = function(num_of_tabs){
var s = '';
for (var i=0; i<num_of_tabs; i++){
s += '\t';
}
//console.log('tabbing done. tabs=' + tabs)
return s;
}
// recursive function that returns a fixed block of <td>......</td>.
var generate_td = function(json){
if (!(typeof(json) == 'object')){
// for primitive data - direct wrap in <td>...</td>
return tab(tabs) + '<td>'+json+'</td>\n';
}else{
// recursive call for objects to open a new sub-table inside the <td>...</td>
// (object[key] may be also an object)
var s = tab(++tabs)+'<td>\n';
s += tab(++tabs)+'<table class="'+css_class+'">\n';
for (var k in json){
s += tab(++tabs)+'<tr>\n';
s += tab(++tabs)+'<td>' + k + '</td>\n';
s += generate_td(json[k]);
s += tab(--tabs)+'</tr>' + tab(--tabs) + '\n';
}
// close the <td>...</td> external block
s += tab(tabs--)+'</table>\n';
s += tab(tabs--)+'</td>\n';
return s;
}
}
// construct the complete HTML code
var html_code = '' ;
html_code += tab(++tabs)+'<table class="'+css_class+'">\n';
html_code += tab(++tabs)+'<tr>\n';
html_code += generate_td(json);
html_code += tab(tabs--)+'</tr>\n';
html_code += tab(tabs--)+'</table>\n';
return html_code;
}
The <context:annotation-config>
tag tells Spring to scan the codebase for automatically resolving dependency requirements of the classes containing @Autowired annotation.
Spring 2.5 also adds support for JSR-250 annotations such as @Resource, @PostConstruct, and @PreDestroy.Use of these annotations also requires that certain BeanPostProcessors be registered within the Spring container. As always, these can be registered as individual bean definitions, but they can also be implicitly registered by including <context:annotation-config>
tag in spring configuration.
Taken from Spring documentation of Annotation Based Configuration
Spring provides the capability of automatically detecting 'stereotyped' classes and registering corresponding BeanDefinitions with the ApplicationContext.
According to javadoc of org.springframework.stereotype:
Stereotypes are Annotations denoting the roles of types or methods in the overall architecture (at a conceptual, rather than implementation, level). Example: @Controller @Service @Repository etc. These are intended for use by tools and aspects (making an ideal target for pointcuts).
To autodetect such 'stereotype' classes, <context:component-scan>
tag is required.
The <context:component-scan>
tag also tells Spring to scan the code for injectable beans under the package (and all its subpackages) specified.
To print a schema, I use jade and do an export to a file of the database then bring it into word to format and print
Similar to Julien's answer above, I had success with the following:
fig, ax = plt.subplots(figsize=(10,4))
for key, grp in df.groupby(['ticker']):
ax.plot(grp['Date'], grp['adj_close'], label=key)
ax.legend()
plt.show()
This solution might be more relevant if you want more control in matlab.
Solution inspired by: https://stackoverflow.com/a/52526454/10521959
To summarise solutions from a couple of questions/answers:
If you want to get the current scroll offset use:
$(document).scrollTop()
To set the scroll offset use:
$('html,body').scrollTop(x)
To animate the scroll use use:
$('html,body').animate({scrollTop: x});
Dir.foreach("/home/mydir") do |fname|
puts fname
end
If someone is still getting errors after applying the accepted solution, it could be possibly because you have a separate module file for the component in which you want to use the ngModel property in input tag. In that case, apply the accepted solution in the component's module.ts file as well.
I've simply added
jQuery.browser = {
msie: false,
version: 0
};
after jquery script, because I don't care about IE anymore.
