Why?: When Wordpress editing your re-write rules, so make sure your HTTPS rule should not be removed! so this is no conflict with native Wordpress rules.
<IfModule mod_rewrite.c>
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) https://%{SERVER_NAME}/$1 [R,L]
</IfModule>
# BEGIN WordPress
<IfModule mod_rewrite.c>
#Your our Wordpress rewrite rules...
</IfModule>
# END WordPress
Note: You have to change WordPress Address & Site Address urls to https://
in General Settings also (wp-admin/options-general.php
)
I know that are are a lot of solution for this issue. The best and the easiest solution is to add .htaccess file in the root directory.
I tried the answers that we provided for this issue however I faced some issues with auth:api guard in Laravel.
Here's the updated solution:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ ^$1 [N]
RewriteCond %{REQUEST_URI} (\.\w+$) [NC]
RewriteRule ^(.*)$ public/$1
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ server.php
</IfModule>
Create the .htaccess file in your root directory and add this code. And everything goes right
I was facing the same issue. I tried below solution : 1. deleted create table code from Up() and related code from Down() method 2. Run update-database command in Package Manager Consol
this solved my problem
Your function has a couple of smallint
parameters.
But in the call, you are using numeric literals that are presumed to be type integer
.
A string literal or string constant ('123'
) is not typed immediately. It remains type "unknown" until assigned or cast explicitly.
However, a numeric literal or numeric constant is typed immediately. Per documentation:
A numeric constant that contains neither a decimal point nor an exponent is initially presumed to be type
integer
if its value fits in typeinteger
(32 bits); otherwise it is presumed to be typebigint
if its value fits in typebigint
(64 bits); otherwise it is taken to be typenumeric
. Constants that contain decimal points and/or exponents are always initially presumed to be typenumeric
.
More explanation and links in this related answer:
Add explicit casts for the smallint
parameters or quote them.
CREATE OR REPLACE FUNCTION f_typetest(smallint)
RETURNS bool AS 'SELECT TRUE' LANGUAGE sql;
Incorrect call:
SELECT * FROM f_typetest(1);
Correct calls:
SELECT * FROM f_typetest('1');
SELECT * FROM f_typetest(smallint '1');
SELECT * FROM f_typetest(1::int2);
SELECT * FROM f_typetest('1'::int2);

Don't get confused with other option the snippet below I am using and will be useful for you too. Put the below htacces in your root.
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ public/ [L]
RewriteRule (.*) public/$1 [L]
</IfModule>
Go to your public directory and put another htaccess file with the code snippet below
<IfModule mod_rewrite.c>
RewriteEngine On
# Removes index.php from ExpressionEngine URLs
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [PT,L]
</IfModule>
Its working... !!!
Laravel Uses below .htaccess
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
My setup was a little different using XAMPP. in httpd-xampp.conf I had to make the following change.
Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
AllowOverride AuthConfig
Require local
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>
change to
Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
AllowOverride AuthConfig
#makes it so I can config the database from anywhere
#change the line below
Require all granted
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>
I need to state that I'm brand new at this so I'm just hacking around but this is how I got it working.
First edit the file /etc/httpd/conf.d/phpMyAdmin.conf and add the additional line to the directory settings:
<Directory /usr/share/phpMyAdmin/>
order deny,allow
deny from all
allow from 127.0.0.1
allow from 192.168.1.0/15
</Directory>
If you wanted to allow access to everybody then you could just change it to:
<Directory /usr/share/phpMyAdmin/>
order allow,deny
allow from all
</Directory>
Allow in all sections of the file.
A restart (service httpd restart) is enough to pick this up.
I found this after 2 days rigorous research, (find it here) and worked just right for me.
You're getting into looping most likely due to these rules:
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
Just comment it out and try again in a new browser.
Check this answer: Set CORS header in Tomcat
Note that you need Tomcat 7.0.41 or higher.
To know where the current instance of Tomcat is located try this:
System.out.println(System.getProperty("catalina.base"));
You'll see the path in the console view.
Then look for /conf/web.xml on that folder, open it and add the lines of the above link.
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
Require all granted
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</LocationMatch>
Good luck!!!!
Try changing Deny from all
to Allow from all
in your conf and see if that helps.
In addition to Permission problems in storage and cache folder and php version issues, there could be another reasons to display blank page without any error message.
For example, I had a redeclare error message without any log and with blank white page. There was a conflict between my own helper function and a vendor function.
I suggest as a starting point, run artisan
commands. for example:
php artisan cache:clear
If there was a problem, it will prompted in terminal and you've got a Clue and you can google for the solution.
I ran into a similar problem today (but with mod_wsgi
). It might be an Apache 2.2-to-2.4 problem. A comprehensive list of changes can be found here.
For me, it helped to add an additional <Directory>
-entry for every path the error-log was complaining about and filling the section with Require all granted
.
So in your case you could try
<Directory /usr/lib/cgi-bin/php5-fcgi>
Require all granted
Options FollowSymLinks
</Directory>
and I had to move my configuration file from folder conf.d
to folder sites-enabled
.
All in all, that did the trick for me, but I don't guarantee it works in your case as well.
When you use Apache with mod_php apache is enforced in prefork
mode, and not worker
. As, even if php5 is known to support multi-thread, it is also known that some php5 libraries are not behaving very well in multithreaded environments (so you would have a locale call on one thread altering locale on other php threads, for example).
So, if php is not running in cgi way like with php-fpm you have mod_php inside apache and apache in prefork mode. On your tests you have simply commented the prefork settings and increased the worker settings, what you now have is default values for prefork settings and some altered values for the shared ones :
StartServers 20
MinSpareServers 5
MaxSpareServers 10
MaxClients 1024
MaxRequestsPerChild 0
This means you ask apache to start with 20 process, but you tell it that, if there is more than 10 process doing nothing it should reduce this number of children, to stay between 5 and 10 process available. The increase/decrease speed of apache is 1 per minute. So soon you will fall back to the classical situation where you have a fairly low number of free available apache processes (average 2). The average is low because usually you have something like 5 available process, but as soon as the traffic grows they're all used, so there's no process available as apache is very slow in creating new forks. This is certainly increased by the fact your PHP requests seems to be quite long, they do not finish early and the apache forks are not released soon enough to treat another request.
See on the last graphic the small amount of green before the red peak? If you could graph this on a 1 minute basis instead of 5 minutes you would see that this green amount was not big enough to take the incoming traffic without any error message.
Now you set 1024
MaxClients
. I guess the cacti graph are not taken after this configuration modification, because with such modification, when no more process are available, apache would continue to fork new children, with a limit of 1024 busy children. Take something like 20MB of RAM per child (or maybe you have a big memory_limit in PHP and allows something like 64MB or 256MB and theses PHP requests are really using more RAM), maybe a DB server... your server is now slowing down because you have only 768MB of RAM. Maybe when apache is trying to initiate the first 20 children you already reach the available RAM limit.
So. a classical way of handling that is to check the amount of memory used by an apache fork (make some top commands while it is running), then find how many parallel request you can handle with this amount of RAM (that mean parallel apache children in prefork mode). Let's say it's 12, for example. Put this number in apache mpm settings this way:
<IfModule prefork.c>
StartServers 12
MinSpareServers 12
MaxSpareServers 12
MaxClients 12
MaxRequestsPerChild 300
</IfModule>
That means you do not move the number of fork while traffic increase or decrease, because you always want to use all the RAM and be ready for traffic peaks. The 300
means you recyclate each fork after 300 requests, it's better than 0, it means you will not have potential memory leaks issues. MaxClients is set to 12 25 or 50 which is more than 12 to handle the (removed this strange sentende, I can't remember why I said that, if more than 12 requests are incoming the next one will be pushed in the Backlog queue, but you should set MaxClient to your targeted number of processes).ListenBacklog
queue, which can enqueue some requests, you may take a bigger queue, but you would get some timeouts maybe
And yes, that means you cannot handle more than 12 parallel requests.
If you want to handle more requests:
If your problem is really traffic peaks, solutions could be available with caches, like a proxy-cache server. If the problem is a random slowness in PHP then... it's an application problem, do you do some HTTP query to another site from PHP, for example?
And finally, as stated by @Jan Vlcinsky you could try nginx, where php will only be available as php-fpm. If you cannot buy RAM and must handle a big traffic that's definitively desserve a test.
Update: About internal dummy connections (if it's your problem, but maybe not).
Check this link and this previous answer. This is 'normal', but if you do not have a simple virtualhost theses requests are maybe hitting your main heavy application, generating slow http queries and preventing regular users to acces your apache processes. They are generated on graceful reload or children managment.
If you do not have a simple basic "It works" default Virtualhost prevent theses requests on your application by some rewrites:
RewriteCond %{HTTP_USER_AGENT} ^.*internal\ dummy\ connection.*$ [NC]
RewriteRule .* - [F,L]
Update:
Having only one Virtualhost does not protect you from internal dummy connections, it is worst, you are sure now that theses connections are made on your unique Virtualhost. So you should really avoid side effects on your application by using the rewrite rules.
Reading your cacti graphics, it seems your apache is not in prefork mode bug in worker mode. Run httpd -l
or apache2 -l
on debian, and check if you have worker.c or prefork.c. If you are in worker mode you may encounter some PHP problems in your application, but you should check the worker settings, here is an example:
<IfModule worker.c>
StartServers 3
MaxClients 500
MinSpareThreads 75
MaxSpareThreads 250
ThreadsPerChild 25
MaxRequestsPerChild 300
</IfModule>
You start 3 processes, each containing 25 threads (so 3*25=75 parallel requests available by default), you allow 75 threads doing nothing, as soon as one thread is used a new process is forked, adding 25 more threads. And when you have more than 250 threads doing nothing (10 processes) some process are killed. You must adjust theses settings with your memory. Here you allow 500 parallel process (that's 20 process of 25 threads). Your usage is maybe more:
<IfModule worker.c>
StartServers 2
MaxClients 250
MinSpareThreads 50
MaxSpareThreads 150
ThreadsPerChild 25
MaxRequestsPerChild 300
</IfModule>
The docs explicitly says that java.sql.Date
will throw:
IllegalArgumentException
- if the date given is not in the JDBC date escape format (yyyy-[m]m-[d]d
)
Also you shouldn't need to convert a date to a String
then to a sql.date
, this seems superfluous (and bug-prone!). Instead you could:
java.sql.Date sqlDate := new java.sql.Date(now.getTime());
prs.setDate(2, sqlDate);
prs.setDate(3, sqlDate);
In case someone is using php7 under a Linux environment
Make sure you enable php7
sudo a2enmod php7
Restart the mysql service and Apache
sudo systemctl restart mysql
sudo systemctl restart apache2
Try
<IfModule mod_rewrite.so>
...
...
...
</IfModule>
instead of <IfModule mod_rewrite.c>
cache:true
only works with GET and HEAD request.
You could roll your own solution as you said with something along these lines :
var localCache = {
data: {},
remove: function (url) {
delete localCache.data[url];
},
exist: function (url) {
return localCache.data.hasOwnProperty(url) && localCache.data[url] !== null;
},
get: function (url) {
console.log('Getting in cache for url' + url);
return localCache.data[url];
},
set: function (url, cachedData, callback) {
localCache.remove(url);
localCache.data[url] = cachedData;
if ($.isFunction(callback)) callback(cachedData);
}
};
$(function () {
var url = '/echo/jsonp/';
$('#ajaxButton').click(function (e) {
$.ajax({
url: url,
data: {
test: 'value'
},
cache: true,
beforeSend: function () {
if (localCache.exist(url)) {
doSomething(localCache.get(url));
return false;
}
return true;
},
complete: function (jqXHR, textStatus) {
localCache.set(url, jqXHR, doSomething);
}
});
});
});
function doSomething(data) {
console.log(data);
}
EDIT: as this post becomes popular, here is an even better answer for those who want to manage timeout cache and you also don't have to bother with all the mess in the $.ajax() as I use $.ajaxPrefilter(). Now just setting {cache: true}
is enough to handle the cache correctly :
var localCache = {
/**
* timeout for cache in millis
* @type {number}
*/
timeout: 30000,
/**
* @type {{_: number, data: {}}}
**/
data: {},
remove: function (url) {
delete localCache.data[url];
},
exist: function (url) {
return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
},
get: function (url) {
console.log('Getting in cache for url' + url);
return localCache.data[url].data;
},
set: function (url, cachedData, callback) {
localCache.remove(url);
localCache.data[url] = {
_: new Date().getTime(),
data: cachedData
};
if ($.isFunction(callback)) callback(cachedData);
}
};
$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
if (options.cache) {
var complete = originalOptions.complete || $.noop,
url = originalOptions.url;
//remove jQuery cache as we have our own localCache
options.cache = false;
options.beforeSend = function () {
if (localCache.exist(url)) {
complete(localCache.get(url));
return false;
}
return true;
};
options.complete = function (data, textStatus) {
localCache.set(url, data, complete);
};
}
});
$(function () {
var url = '/echo/jsonp/';
$('#ajaxButton').click(function (e) {
$.ajax({
url: url,
data: {
test: 'value'
},
cache: true,
complete: doSomething
});
});
});
function doSomething(data) {
console.log(data);
}
And the fiddle here CAREFUL, not working with $.Deferred
Here is a working but flawed implementation working with deferred:
var localCache = {
/**
* timeout for cache in millis
* @type {number}
*/
timeout: 30000,
/**
* @type {{_: number, data: {}}}
**/
data: {},
remove: function (url) {
delete localCache.data[url];
},
exist: function (url) {
return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
},
get: function (url) {
console.log('Getting in cache for url' + url);
return localCache.data[url].data;
},
set: function (url, cachedData, callback) {
localCache.remove(url);
localCache.data[url] = {
_: new Date().getTime(),
data: cachedData
};
if ($.isFunction(callback)) callback(cachedData);
}
};
$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
if (options.cache) {
//Here is our identifier for the cache. Maybe have a better, safer ID (it depends on the object string representation here) ?
// on $.ajax call we could also set an ID in originalOptions
var id = originalOptions.url+ JSON.stringify(originalOptions.data);
options.cache = false;
options.beforeSend = function () {
if (!localCache.exist(id)) {
jqXHR.promise().done(function (data, textStatus) {
localCache.set(id, data);
});
}
return true;
};
}
});
$.ajaxTransport("+*", function (options, originalOptions, jqXHR, headers, completeCallback) {
//same here, careful because options.url has already been through jQuery processing
var id = originalOptions.url+ JSON.stringify(originalOptions.data);
options.cache = false;
if (localCache.exist(id)) {
return {
send: function (headers, completeCallback) {
completeCallback(200, "OK", localCache.get(id));
},
abort: function () {
/* abort code, nothing needed here I guess... */
}
};
}
});
$(function () {
var url = '/echo/jsonp/';
$('#ajaxButton').click(function (e) {
$.ajax({
url: url,
data: {
test: 'value'
},
cache: true
}).done(function (data, status, jq) {
console.debug({
data: data,
status: status,
jqXHR: jq
});
});
});
});
Fiddle HERE Some issues, our cache ID is dependent of the json2 lib JSON object representation.
Use Console view (F12) or FireBug to view some logs generated by the cache.
Since there is no php.ini file in your /public_html directory......create a new file as phpinfo.php in /public_html directory
-Type this code in phpinfo.php and save it:
<?php
phpinfo();
?>
-Then type yourdomain.com/phpinfo.php...you will see all the details of your configuration
-To edit that config, create another file as php.ini in /public_html directory and paste this code:
memory_limit=512M
post_max_size=200M
upload_max_filesize=200M
-And then refresh yourdomain.com/phpinfo.php and see the changes,it will be done.
//Just add
RewriteBase /
//after
RewriteEngine On
//and you are done....
//so it should be

RewriteRule ^ index.php [QSA,L]
you have to use the 'prop' function :
.prop('checked', true);
Before jQuery 1.6 (see user2063626's answer):
.attr('checked','checked')
I had the same problem. All I did to fix the issue was to modify my htacces file like this:
<IfModule mod_rewrite.c>

RewriteCond %{HTTP_HOST} ^mywebsite.com [NC]
RewriteRule ^(.*)$ http://www.mywebsite.com/$1 [L,R=301]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteRule ^index.php/(.*)$ [L]
</IfModule>
Michals answer worked for me, albeit with one small modification:
Problem:
when you have a single site security certificate, a browser that tries to access your page without https:// www. (or whichever domain your certificate covers) will display an ugly red warning screen before it even gets to receive the redirect to the safe and correct https page.
Solution
First use the redirect to the www (or whichever domain is covered by your certificate) and only then do the https redirect. This will ensure that your users are not confronted with any error because your browser sees a certificate that doesn't cover the current url.
#First rewrite any request to the wrong domain to use the correct one (here www.)
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
#Now, rewrite to HTTPS:
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
If your host not at pvn or dedicated, it's dificult to restart server.
Better solution from me, just edit your CSS file (at another domain or your subdomain) that call font eot, woff etc to your origin (your-domain or www yourdomain). it will solve your problem.
I mean, edit relative url on css to absolute url origin domain
I used http://jafty.com/blog/enable-mod_rewrite-on-apache-ec2-linux-server/ to determine that after upgrading to PHP 5.6 (from 4.9.13) it also update the http (Apache) and I needed to edit the /etc/httpd/conf/httpd.conf file, I quote...
Basically, you’ll be adding All insted of None to AllowOverride, you do not want to edit the main directory configuration, you want to edit the one that looks like this:
<Directory “/var/www/html”>
Not:
<Directory />
Then restart Apache with:
sudo service httpd restart
NOTE - in my tiredness I did change a different Directory element and it made no difference, so ensure you do it for /var/www/html
The article also explains how to check mod-rewrite is enabled.

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.
Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.
The best documentation you'll find on the topic is the virtual host documentation in the apache manual.
There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.
The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost
line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost
entry for each port.
Assuming you're starting from scratch, this is much simpler than it may seem.
If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.
NameVirtualHost *:80
If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost
directive, and it will be removed in a future version.
Now your vhost definitions:
<VirtualHost *:80>
DocumentRoot "/home/user/site1/"
ServerName site1
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "/home/user/site2/"
ServerName site2
</VirtualHost>
You can run as many sites as you want on the same port. The ServerName
being different is enough to tell Apache which vhost to use. Also, the ServerName
directive is always the domain/hostname and should never include a path.
If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81
In your .htaccess you can add:
PHP 5.x
<IfModule mod_php5.c>
php_value memory_limit 64M
</IfModule>
PHP 7.x
<IfModule mod_php7.c>
php_value memory_limit 64M
</IfModule>
If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.
If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

If you are using MAMP Pro the way to fix this is by checking the Indexes

In MAMP Pro v3.0.3 this is what that looks like:
I experienced a similar issue. None of the suggestions above helped me, though.
Eventually I realized that the Wordpress MySQL-user on my production environment had not been assigned sufficient privileges.
I am using xampp 1.7.3. Using inspiration from here: xampp 1.7.3 upgrade broken virtual hosts access forbidden

Here is what I add in httpd.conf:
<Directory "D:/CofeeShop">
AllowOverride All
Options All

And here is what I add in httpd-vhosts.conf
<VirtualHost *:8001>

I also add Listen 8001
in httpd.conf to complete my setting.
Hope it helps
The other option for using PHP scripts sans extension is
Options +MultiViews
Or even just following in the directories .htaccess
:
DefaultType application/x-httpd-php
The latter allows having all filenames without extension script
being treated as PHP scripts. While MultiViews makes the webserver look for alternatives, when just the basename is provided (there's a performance hit with that however).
You can set "access plus 1 seconds" and that way it will refresh the next time the user enters the site. Keep the setting for one month.
I was having the exact problem, I solved it by clicking custom structure, then adding /index.php/%postname%/
and it works
Hope this saves someone the stress that I went through finding what the heck was wrong with it.
First we need to check if we have enabled mod_headers.c and mod_expires.c.
sudo apache2 -l
If we don't have it, we need to enable them
sudo a2enmod headers
Then we need to restart apache
sudo apache2 restart
At last, add the rules on .htaccess (seen on other answers), for example

I wasn't able to use the 403 method because I wanted the maintenance page and page images in a sub folder on my server, so used the following approach to redirect to a 'maintenance page' for everyone but a single IP*
RewriteEngine on
RewriteCond %{REMOTE_ADDR} !**.**.**.*
RewriteRule !^maintenance/ http://www.website.co.uk/maintenance/ [R=302,L]
click: WAMP icon->Apache->Apache modules->chose rewrite_module
and do restart for all services.
Oh, I hate % design for this too....
You may convert dividend to unsigned in a way like:
unsigned int offset = (-INT_MIN) - (-INT_MIN)%divider
result = (offset + dividend) % divider
where offset is closest to (-INT_MIN) multiple of module, so adding and subtracting it will not change modulo. Note that it have unsigned type and result will be integer. Unfortunately it cannot correctly convert values INT_MIN...(-offset-1) as they cause arifmetic overflow. But this method have advandage of only single additional arithmetic per operation (and no conditionals) when working with constant divider, so it is usable in DSP-like applications.
There's special case, where divider is 2N (integer power of two), for which modulo can be calculated using simple arithmetic and bitwise logic as
dividend&(divider-1)
for example
x mod 2 = x & 1
x mod 4 = x & 3
x mod 8 = x & 7
x mod 16 = x & 15
More common and less tricky way is to get modulo using this function (works only with positive divider):
int mod(int x, int y) {
int r = x%y;
return r<0?r+y:r;
}
This just correct result if it is negative.
Also you may trick:
(p%q + q)%q
It is very short but use two %-s which are commonly slow.
Check this following steps
2.
change the MaxClients directive. it is now on 256.
I thought the regular modulus operator would work for this in java, but it can't be hard to code. Just divide the numerator by the denominator, and take the integer portion of the result. Multiply that by the denominator, and subtract the result from the numerator.
x = n / d
xint = Integer portion of x
result = n - d * xint
I had the same problem, but nothing above worked...try a really simple solution...
Back up your .htaccess file. Delete it from your root directory. Then try accessing those directories. Its likely that whatever rewrite conditions you had in your file were causing those access issues. The index page should be picked up automatically on most hosts. :P
This is intended behavior.
When you make an HTTP request, the server normally returns code 200 OK
. If you set If-Modified-Since
, the server may return 304 Not modified
(and the response will not have the content). This is supposed to be your cue that the page has not been modified.
The authors of the class have foolishly decided that 304
should be treated as an error and throw an exception. Now you have to clean up after them by catching the exception every time you try to use If-Modified-Since
.
legend
and/or colors
to some vertical lines, then use this:import matplotlib.pyplot as plt
# x coordinates for the lines
xcoords = [0.1, 0.3, 0.5]
# colors for the lines
colors = ['r','k','b']
for xc,c in zip(xcoords,colors):
plt.axvline(x=xc, label='line at x = {}'.format(xc), c=c)
plt.legend()
plt.show()
Results:
You did forget to include stdafx.h
in your source (as I cannot see it your code). If you didn't, then make sure #include "stdafx.h"
is the first line in your .cpp
file, otherwise you will see the same error even if you've included "stdafx.h"
in your source file (but not in the very beginning of the file).
The suggested technique above in Dave's answer is certainly a good design practice, and yes ultimately the required permission must be set in the AndroidManifest.xml file to access the external storage.
However, the Mono-esque way to add most (if not all, not sure) "manifest options" is through the attributes of the class implementing the activity (or service).
The Visual Studio Mono plugin automatically generates the manifest, so its best not to manually tamper with it (I'm sure there are cases where there is no other option).
For example:
[Activity(Label="MonoDroid App", MainLauncher=true, Permission="android.permission.WRITE_EXTERNAL_STORAGE")]
public class MonoActivity : Activity
{
protected override void OnCreate(Bundle bindle)
{
base.OnCreate(bindle);
}
}
The process handle will be signaled if it exits.
So the following will work (error handling removed for brevity):
BOOL IsProcessRunning(DWORD pid)
{
HANDLE process = OpenProcess(SYNCHRONIZE, FALSE, pid);
DWORD ret = WaitForSingleObject(process, 0);
CloseHandle(process);
return ret == WAIT_TIMEOUT;
}
Note that process ID's can be recycled - it's better to cache the handle that is returned from the CreateProcess call.
You can also use the threadpool API's (SetThreadpoolWait on Vista+, RegisterWaitForSingleObject on older platforms) to receive a callback when the process exits.
EDIT: I missed the "want to do something to the process" part of the original question. You can use this technique if it is ok to have potentially stale data for some small window or if you want to fail an operation without even attempting it. You will still have to handle the case where the action fails because the process has exited.
A couple of years late to the party, but I had a requirement to do this for both past and future dates, so I combined Jeff's and Vincent's into this. It's a ternarytastic extravaganza! :)

Here is a custom function I have made, to make the things clear for you, related to get the data of an order ID. You will see all the different RAW outputs you can get and how to get the data you need…
Using print_r()
function (or var_dump()
function too) allow to output the raw data of an object or an array.
So first I output this data to show the object or the array hierarchy. Then I use different syntax depending on the type of that variable (string, array or object) to output the specific data needed.
IMPORTANT: With
$order
object you can use most ofWC_order
orWC_Abstract_Order
methods (using the object syntax)…
Here is the code:
function get_order_details($order_id){
// 1) Get the Order object
$order = wc_get_order( $order_id );
// OUTPUT
echo '<h3>RAW OUTPUT OF THE ORDER OBJECT: </h3>';
print_r($order);

echo 'And so on ……… <br><br>';
echo '- - - - - - - - - - - - - <br><br>';
}
echo '- - - - - - E N D - - - - - <br><br>';
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Usage (if your order ID is 159 for example):
get_order_details(159);
This code is tested and works.

You could use Narrative JavaScript, a compiler that will transforms your code into a state machine, effectively allowing you to emulate threading. It does so by adding a "yielding" operator (notated as '->') to the language that allows you to write asynchronous code in a single, linear code block.

From SQL 2008 you can use DATE datatype so you can simply do:
SELECT CONVERT(DATE,GETDATE())
OR
Select * from [User] U
where CONVERT(DATE,U.DateCreated) = '2014-02-07'
You can, in Firefox it works, add the attribute target="_newtab" to the anchor to force the opening of a new tab.
<a href="some url" target="_newtab">content of the anchor</a>
In javascript you can use
window.open('page.html','_newtab');
Said that, I partially agree with Sam. You shouldn't force user to open new pages or new tab without showing them a hint on what is going to happen before they click on the link.
Let me know if it works on other browser too (I don't have a chance to try it on other browser than Firefox at the moment).

I thought it went without saying, but connecting to a database with Java requires a JDBC driver. You'll need the MySQL JDBC driver.
Maybe you can connect using a socket over TCP/IP. Check out the MySQL docs.

From msdn:
The order of the returned file names is not guaranteed; use the Sort() method if a specific sort order is required.
The Sort() method is the standard Array.Sort(), which takes in IComparables (among other overloads), so if you sort by creation date, it will handle localization based on the machine settings.
My WPF project referenced 3 custom dlls. I updated one of them, deleted the reference and added the reference to the new dll. It also showed the correct version number in the properties of the reference. It was rebuilding without an error.
But when the application was running, the failure "The located assembly's manifest .." occured, mentioning the old version.
After searching for a solution for hours and reading couple of threads like this, I remembered the other dlls. One of the other dlls was referencing the old version, and that's why the failure occured. After rebuilding the 2nd dll and recreating both references in my WPF project, the failure was gone.
Don't forget to check your other dlls!

I see that BigDecimal has an inflate() method on equals() method. What does inflate() do actually?
Basically, inflate()
calls BigInteger.valueOf(intCompact)
if necessary, i.e. it creates the unscaled value that is stored as a BigInteger
from long intCompact
. If you don't need that BigInteger
and the unscaled value fits into a long
BigDecimal
seems to try to save space as long as possible.
You can use the encoded flag on the @Path

, however, so you still can't pass in dynamic query strings.One problem is that you are using count
to refer both to the position in the word that you are checking, and the number of char
you have seen, and you are using char
to refer both to the input character you are checking, and the current character in the string. Use separate variables instead.
Also, move the return
statement outside the loop; otherwise you will always return after checking the first character.
Finally, you only need one loop to iterate over the string. Get rid of the outer while
loop and you will not need to track the position in the string.
Taking these suggestions, your code would look like this:
def count_letters(word, char):
count = 0
for c in word:
if char == c:
count += 1
return count
You can use:
var tomorrow = new Date();
tomorrow.setDate(new Date().getDate()+1);
For example, since there are 30 days in April, the following code will output May 1:
var day = new Date('Apr 30, 2000');
console.log(day); // Apr 30 2000
var nextDay = new Date(day);
nextDay.setDate(day.getDate() + 1);
console.log(nextDay); // May 01 2000

This assumes your field length will never exceed 100, but you can make it smarter to account for that if necessary by employing the LEN()

Of course! Just use the ALTER TABLE...
syntax.
Example
ALTER TABLE YourTable
ADD Foo INT NULL /*Adds a new int column existing rows will be
given a NULL value for the new column*/
Or
ALTER TABLE YourTable
ADD Bar INT NOT NULL DEFAULT(0) /*Adds a new int column existing rows will
be given the value zero*/
In SQL Server 2008 the first one is a metadata only change. The second will update all rows.
In SQL Server 2012+ Enterprise edition the second one is a metadata only change too.
The entire shortcut list can be found here: http://iphonehuston.blogspot.com/2009/08/shortcuts-for-xcode.html

While this does not answer the question asked, it answers a related question that many people have had:
x <-c(1,2,3)
y <-c(100,200,300)
x_name <- "cond"
y_name <- "rating"
df <- data.frame(x,y)
names(df) <- c(x_name,y_name)
print(df)
cond rating
1 1 100
2 2 200
3 3 300
Declare @string varchar(1000)
DECLARE @SearchString varchar(100)
Set @string = 'as as df df as as as'
SET @SearchString = 'as'
select ((len(@string) - len(replace(@string, @SearchString, ''))) -(len(@string) -
len(replace(@string, @SearchString, ''))) % 2) / len(@SearchString)
Use forward slashes. See explanation here
Nil Coalescing Operator can be used as well.
rowName = rowName != nil ?rowName!.stringFromCamelCase():""
If you have a numpy array you can do this:
import numpy as np
from matplotlib import pyplot as plt
data = np.array([
[1, 2],
[2, 3],
[3, 6],
])
x, y = data.T
plt.scatter(x,y)
plt.show()
For those of us using ASP.NET MVC 4 - this may be helpful.
First, I added a BundleConfig class in the App_Start folder.
Here’s my code that I used to create it:
using System.Web.Optimization;
public class BundleConfig
{
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/SiteMaster.css"));
}
}
Second, I registered the BundleConfig class in the Global.asax file:
protected void Application_Start()
{
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
Third, I added style helpers to the my CSS file:
/* Styles for validation helpers */
.field-validation-error {
color: red;
font-weight: bold;
}
.field-validation-valid {
display: none;
}
input.input-validation-error {
border: 1px solid #e80c4d;
}
input[type="checkbox"].input-validation-error {
border: 0 none;
}
.validation-summary-errors {
color: #e80c4d;
font-weight: bold;
font-size: 1.1em;
}
.validation-summary-valid {
display: none;
}
Finally I used this syntax in any View:
@Styles.Render("~/Content/css")
I once saw a macro package that would alias every C keyword to let you effectively program in Klingon. That's right, Klingon. (Un)fortunately, the project was abandoned and taken down several years ago.
SQLite out-of-the-box is not really feature-full regarding concurrency. You will get into trouble if you have hundreds of web requests hitting the same SQLite database.
You should definitely go with MySQL or PostgreSQL.
If it is for a single-person project, SQLite will be easier to setup though.
Follow up to accepted answer.
You need something other than CTRL-D to designate the end if using this in a script. Try this instead:
cat << EOF >> filename
This is text entered via the keyboard or via a script.
EOF
This will append text to the stated file (not including "EOF").
It utilizes a here document (or heredoc).
However if you need sudo to append to the stated file, you will run into trouble utilizing a heredoc due to I/O redirection if you're typing directly on the command line.
This variation will work when you are typing directly on the command line:
sudo sh -c 'cat << EOF >> filename
This is text entered via the keyboard.
EOF'
Or you can use tee
instead to avoid the command line sudo issue seen when using the heredoc with cat:
tee -a filename << EOF
This is text entered via the keyboard or via a script.
EOF
I also made a fairly simple function. You call on it by: get("yourgetname");
and get whatever there was. (now that i wrote it i noticed it will give you %26 if you had a & in your value..)
function get(name){
var url = window.location.search;
var num = url.search(name);
var namel = name.length;
var frontlength = namel+num+1; //length of everything before the value
var front = url.substring(0, frontlength);
url = url.replace(front, "");
num = url.search("&");
if(num>=0) return url.substr(0,num);
if(num<0) return url;
}
To use both is a nice answer; it's not a question of either or.
The advantage of using both is that the CSS will hide the element immediately when the page loads. The jQuery .hide will flash the element for a quarter of a second then hide it.
In the case when we want to have the element not shown when the page loads we can use CSS and set display:none & use the jQuery .hide(). If we plan to toggle the element we can use jQuery toggle.
From my experience, the problem not with EF, but with ORM approach itself.
In general all ORMs suffers from N+1 problem not optimized queries and etc. My best guess would be to track down queries that causes performance degradation and try to tune-up ORM tool, or rewrite that parts with SPROC.
I used used fadeIn animation to replace new image for old one
ObjectAnimator.ofFloat(imageView, View.ALPHA, 0.2f, 1.0f).setDuration(1000).start();

I guess pretty much the same rules that apply to relation databases should apply here. And after so many decades there is still no agreement whether RDBMS tables should be named singular or plural...
MongoDB speaks JavaScript, so utilize JS naming conventions of camelCase.
MongoDB official documentation mentions you may use underscores, also built-in identifier is named _id
(but this may be be to indicate that _id
is intended to be private, internal, never displayed or edited.
The listed return type of the method is Task<string>
. You're trying to return a string
. They are not the same, nor is there an implicit conversion from string to Task<string>
, hence the error.
You're likely confusing this with an async
method in which the return value is automatically wrapped in a Task
by the compiler. Currently that method is not an async method. You almost certainly meant to do this:
private async Task<string> methodAsync()
{
await Task.Delay(10000);
return "Hello";
}
There are two key changes. First, the method is marked as async
, which means the return type is wrapped in a Task
, making the method compile. Next, we don't want to do a blocking wait. As a general rule, when using the await
model always avoid blocking waits when you can. Task.Delay
is a task that will be completed after the specified number of milliseconds. By await
-ing that task we are effectively performing a non-blocking wait for that time (in actuality the remainder of the method is a continuation of that task).
If you prefer a 4.0 way of doing it, without using await
, you can do this:
private Task<string> methodAsync()
{
return Task.Delay(10000)
.ContinueWith(t => "Hello");
}
The first version will compile down to something that is more or less like this, but it will have some extra boilerplate code in their for supporting error handling and other functionality of await
we aren't leveraging here.
If your Thread.Sleep(10000)
is really meant to just be a placeholder for some long running method, as opposed to just a way of waiting for a while, then you'll need to ensure that the work is done in another thread, instead of the current context. The easiest way of doing that is through Task.Run
:
private Task<string> methodAsync()
{
return Task.Run(()=>
{
SomeLongRunningMethod();
return "Hello";
});
}
Or more likely:
private Task<string> methodAsync()
{
return Task.Run(()=>
{
return SomeLongRunningMethodThatReturnsAString();
});
}
This Should work Making it Round to 2 Point
int a=53214
parseFloat(Math.round(a* 100) / 100).toFixed(2);
Just a reminder on adding columns. If one of the values is NULL the total of those columns becomes NULL. Thus why some posters have recommended coalesce with the second parameter being 0
I know this was an older posting but wanted to add this for completeness.
Looks like you forgot the @ in variable declaration. Also I remember having problems with SET
in MySql a long time ago.
Try
DECLARE @FOO varchar(7);
DECLARE @oldFOO varchar(7);
SELECT @FOO = '138';
SELECT @oldFOO = CONCAT('0', @FOO);
update mypermits
set person = @FOO
where person = @oldFOO;
You can use below code if object has attibutes under it.
String getCommonSeperatedString(List<ActionObject> actionObjects) {
StringBuffer sb = new StringBuffer();
for (ActionObject actionObject : actionObjects){
sb.append(actionObject.Id).append(",");
}
sb.deleteCharAt(sb.lastIndexOf(","));
return sb.toString();
}
You need spaces around the operator =~
i="test" if [[ $i =~ "200[78]" ]]; then echo "OK" else echo "not OK" fi
You can add header "Content-Type: text/html; charset=UTF-8" to your message body.
$headers = "Content-Type: text/html; charset=UTF-8";
If you use native mail()
function $headers array will be the 4th parameter
mail($to, $subject, $message, $headers)
If you user PEAR Mail::factory() code will be:
$smtp = Mail::factory('smtp', $params);
$mail = $smtp->send($to, $headers, $body);
You can try
$string = "this is the test for string." ;
$string = str_replace(' ', '_', $string);
$string = substr($string,0,10);
var_dump($string);
Output
this_is_th
The latest version of SSPI (bundled with Windows 7) has an implementation of TLS 1.2, which can be found in schannel.dll
To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
If you care for it to be in the same order as before you can use a common table expression for that:
;WITH CTE AS (
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
)
SELECT *
FROM CTE
ORDER BY MySortColumn
This worked best.
(from p in Context.person_account_portfolio
where p.person_id == personId select p).ToList()
.ForEach(x => x.is_default = false);
Context.SaveChanges();
Running:
npm install
from inside your app directory (i.e. where package.json is located) will install the dependencies for your app, rather than install it as a module, as described here. These will be placed in ./node_modules relative to your package.json file (it's actually slightly more complex than this, so check the npm docs here).
You are free to move the node_modules dir to the parent dir of your app if you want, because node's 'require' mechanism understands this. However, if you want to update your app's dependencies with install/update, npm will not see the relocated 'node_modules' and will instead create a new dir, again relative to package.json.
To prevent this, just create a symlink to the relocated node_modules from your app dir:
ln -s ../node_modules node_modules
This should work for you:
var date1 = new Date(year, month, day, hour, minute, seconds);
I had to create date form a string so I have done it like this:
var d = '2013-07-20 16:57:27';
var date1 = new Date(d.substr(0, 4), d.substr(5, 2), d.substr(8, 2), d.substr(11, 2), d.substr(14, 2), d.substr(17, 2));
Remember that the months in javascript are from 0 to 11, so you should reduce the month value by 1, like this:
var d = '2013-07-20 16:57:27';
var date1 = new Date(d.substr(0, 4), d.substr(5, 2) - 1, d.substr(8, 2), d.substr(11, 2), d.substr(14, 2), d.substr(17, 2));
From the Object.toString
docs:
Returns a string representation of the object. In general, the
toString
method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.The
toString
method for classObject
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
Example:
String[] mystr ={"a","b","c"};
System.out.println("mystr.toString: " + mystr.toString());
output:- mystr.toString: [Ljava.lang.String;@13aaa14a
You can use javaagent to modify the java class bytes ,add the monitor codes dynamically.there is some open source tools on the github that can do this for you.
If you want to do it by yourself, just implements the javaagent,use javassist to modify the methods you want to monitor,and the monitor code before your method return.it's clean and you can monitor systems that you even don't have source code.
Ctrl+Space should do it.
While Matt B's may be true in one sense, it may help to think of Java multidimensional array without thinking about geometeric matrices at all. Java multi-dim arrays are simply arrays of arrays, and each element of the first-"dimension" can be of different size from the other elements, or in fact can actually store a null "sub"-array. See comments under this question
NOTE: When using fgets(), the last character in the array will be '\n' at times when you use fgets() for small inputs in CLI (command line interpreter) , as you end the string with 'Enter'. So when you print the string the compiler will always go to the next line when printing the string. If you want the input string to have null terminated string like behavior, use this simple hack.
#include<stdio.h>
int main()
{
int i,size;
char a[100];
fgets(a,100,stdin);;
size = strlen(a);
a[size-1]='\0';
return 0;
}
Update: Updated with help from other users.
Ugg! This turned out to simply be a Java version issue for me. I got the handshake error using JRE 1.6 and everything worked perfectly using JRE 1.8.0_144.
Here is an example which answers the question of returning the parameters of a class. Moreover, it still respects the chain of inheritance, i.e. only the parameters of the class itself are returned. The function get_params
is added as a simple example, but other functionalities can be added thanks to the inspect module.
import inspect
class Parent:
@classmethod
def get_params(my_class):
return list(inspect.signature(my_class).parameters.keys())
class OtherParent:
def __init__(self, a, b, c):
pass
class Child(Parent, OtherParent):
def __init__(self, x, y, z):
pass
print(Child.get_params())
>>['x', 'y', 'z']
Try like this
<script>
$(document).ready(function(){
$("#order_ship_date").datepicker({
changeMonth:true,
changeYear:true,
dateFormat:"yy-mm-dd",
minDate: +2,
});
});
</script>
html code is given below
<input id="order_ship_date" type="text" class="input" style="width:80px;" />
There are various alternative answers at this previous question - which admittedly was targeting an integer array as the source, but received generalised answers.
If the same error is on appcompat
implementation 'com.android.support:appcompat-v7:27.0.1'
then adding design
solved it.
implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'
For me, adding
implementation 'de.mrmaffen:vlc-android-sdk:2.0.6'
was including appcompat-v7:23.1.1
in
.idea/libraries
without vlc
, appcompat
alone is enough.
String input = "hello I'm a java dev" +

String fixedInput = input.replaceAll("(java|job|senior)", "<b>$1</b>");
If you've exported the environment variable:
export demoPath=/usr/local/demo
you can simply refer to it by name in the makefile
(make
imports all the environment variables you have set):
DEMOPATH = ${demoPath} # Or $(demoPath) if you prefer.
If you've not exported the environment variable, it is not accessible until you do export it, or unless you pass it explicitly on the command line:
make DEMOPATH="${demoPath}" …
If you are using a C shell derivative, substitute setenv demoPath /usr/local/demo
for the export
command.
When encoding query values, either form, plus or percent-20, is valid; however, since the bandwidth of the internet isn't infinite, you should use plus, since it's two fewer bytes.
In component.ts add this function
_keyUp(event: any) {
const pattern = /[0-9\+\-\ ]/;
let inputChar = String.fromCharCode(event.key);
if (!pattern.test(inputChar)) {
// invalid character, prevent input
event.preventDefault();
}
}
In your template use the following
<input(keyup)="_keyUp($event)">
This will catch the input before angular2 catches the event.
In shell you can use cal -j YYYY
which prints the julian day of the year, If the last julian day is 366, then it is a leap year.
$ function check_leap_year
{
year=$1
if [ `cal -j $year | awk 'NF>0' | awk 'END { print $NF } '` -eq 366 ];
then
echo "$year -> Leap Year";
else
echo "$year -> Normal Year" ;
fi
}
$ check_leap_year 1900
1900 -> Normal Year
$ check_leap_year 2000
2000 -> Leap Year
$ check_leap_year 2001
2001 -> Normal Year
$ check_leap_year 2020
2020 -> Leap Year
$
Using awk, you can do
$ awk -v year=1900 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
365
$ awk -v year=2000 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
366
$ awk -v year=2001 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
365
$ awk -v year=2020 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
366
$
You can get the actual height of called layout with this code:
public int getLayoutSize() {
// Get the layout id
final LinearLayout root = (LinearLayout) findViewById(R.id.mainroot);
final AtomicInteger layoutHeight = new AtomicInteger();
root.post(new Runnable() {
public void run() {
Rect rect = new Rect();
Window win = getWindow(); // Get the Window
win.getDecorView().getWindowVisibleDisplayFrame(rect);
// Get the height of Status Bar
int statusBarHeight = rect.top;
// Get the height occupied by the decoration contents
int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();
// Calculate titleBarHeight by deducting statusBarHeight from contentViewTop
int titleBarHeight = contentViewTop - statusBarHeight;
Log.i("MY", "titleHeight = " + titleBarHeight + " statusHeight = " + statusBarHeight + " contentViewTop = " + contentViewTop);
// By now we got the height of titleBar & statusBar
// Now lets get the screen size
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int screenHeight = metrics.heightPixels;
int screenWidth = metrics.widthPixels;
Log.i("MY", "Actual Screen Height = " + screenHeight + " Width = " + screenWidth);
// Now calculate the height that our layout can be set
// If you know that your application doesn't have statusBar added, then don't add here also. Same applies to application bar also
layoutHeight.set(screenHeight - (titleBarHeight + statusBarHeight));
Log.i("MY", "Layout Height = " + layoutHeight);
// Lastly, set the height of the layout
FrameLayout.LayoutParams rootParams = (FrameLayout.LayoutParams)root.getLayoutParams();
rootParams.height = layoutHeight.get();
root.setLayoutParams(rootParams);
}
});
return layoutHeight.get();
}
Method 4 is my preferred method. The short circuit of the && operator makes the code the most readable. Method 3, Catching NullPointerException, is frowned upon most of the time when a simple null check would suffice.
Based on the answer of massimo virgilio, I've also managed to do it with slf4j-log4j using introspection. HTH.
Logger LOG = LoggerFactory.getLogger(MyOwnClass.class);
org.apache.logging.slf4j.Log4jLogger LOGGER = (org.apache.logging.slf4j.Log4jLogger) LOG;
try {
Class loggerIntrospected = LOGGER.getClass();
Field fields[] = loggerIntrospected.getDeclaredFields();
for (int i = 0; i < fields.length; i++) {
String fieldName = fields[i].getName();
if (fieldName.equals("logger")) {
fields[i].setAccessible(true);
org.apache.logging.log4j.core.Logger loggerImpl = (org.apache.logging.log4j.core.Logger) fields[i].get(LOGGER);
loggerImpl.setLevel(Level.DEBUG);
}
}
} catch (Exception e) {
System.out.println("ERROR :" + e.getMessage());
}
From the answer of @Vicent, I already restore MySQL database as below:
Step 1. Shutdown Mysql server
Step 2. Copy database in your database folder (in linux, the default location is /var/lib/mysql). Keep same name of the database, and same name of database in mysql mode.
sudo cp -rf /mnt/ubuntu_426/var/lib/mysql/database1 /var/lib/mysql/
Step 3: Change own and change mode the folder:
sudo chown -R mysql:mysql /var/lib/mysql/database1
sudo chmod -R 660 /var/lib/mysql/database1
sudo chown mysql:mysql /var/lib/mysql/database1
sudo chmod 700 /var/lib/mysql/database1
Step 4: Copy ibdata1 in your database folder
sudo cp /mnt/ubuntu_426/var/lib/mysql/ibdata1 /var/lib/mysql/
sudo chown mysql:mysql /var/lib/mysql/ibdata1
Step 5: copy ib_logfile0 and ib_logfile1 files in your database folder.
sudo cp /mnt/ubuntu_426/var/lib/mysql/ib_logfile0 /var/lib/mysql/
sudo cp /mnt/ubuntu_426/var/lib/mysql/ib_logfile1 /var/lib/mysql/
Remember change own and change root of those files:
sudo chown -R mysql:mysql /var/lib/mysql/ib_logfile0
sudo chown -R mysql:mysql /var/lib/mysql/ib_logfile1
or
sudo chown -R mysql:mysql /var/lib/mysql
Step 6 (Optional): My site has configuration to store files in a specific location, then I copy those to corresponding location, exactly.
Step 7: Start your Mysql server. Everything come back and enjoy it.
That is it.

Actually, I believe you want to use the __getattr__
special method instead.
Quote from the Python docs:
__getattr__( self, name)
Called when an attribute lookup has not found the attribute in the usual places (i.e. it is not an instance attribute nor is it found in the class tree for self). name is the attribute name. This method should return the (computed) attribute value or raise an AttributeError exception.
Note that if the attribute is found through the normal mechanism,__getattr__()
is not called. (This is an intentional asymmetry between__getattr__()
and__setattr__()
.) This is done both for efficiency reasons and because otherwise__setattr__()
would have no way to access other attributes of the instance. Note that at least for instance variables, you can fake total control by not inserting any values in the instance attribute dictionary (but instead inserting them in another object). See the__getattribute__()
method below for a way to actually get total control in new-style classes.
Note: for this to work, the instance should not have a test
attribute, so the line self.test=20
should be removed.
I wanted to throw this up for good measure. I think the way @micahtan posted is preferred.
typeof(MyProgram).Name
use like this:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dedline);
WebView myWebView = (WebView) findViewById(R.id.webView1);
myWebView.setWebViewClient(new WebViewClient());
myWebView.loadUrl("https://google.com");
}
Setup JAVA_OPTS as a system variable with the following content:
JAVA_OPTS="-Xms256m -Xmx512m"
After that in a command prompt run the following commands:
SET JAVA_OPTS="-Xms256m -Xmx512m"
This can be explained as follows:
These values should be changed according to application requirements.
EDIT:
You can also try adding it through the Environment Properties menu which can be found at:
EDIT 2:
JAVA_OPTS is a system variable that stores various settings/configurations for your local Java Virtual Machine. By having JAVA_OPTS set as a system variable all applications running on top of the JVM will take their settings from this parameter.
To setup a system variable you have to complete the steps listed above from 1 to 4.
Quite a bit late, but a duplicate answer that doesn't require altering the padding or adding extra divs can be found here: Have an issue with box-shadow Inset bottom only. It says, "Use a negative value for the fourth length which defines the spread distance. This is often overlooked, but supported by all major browsers"
From the answerer's fiddle:
box-shadow: inset 0 -10px 10px -10px #000000;
A slightly less verbose way of declaring named enumerations:
object WeekDay extends Enumeration("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat") {
type WeekDay = Value
val Sun, Mon, Tue, Wed, Thu, Fri, Sat = Value
}
WeekDay.valueOf("Wed") // returns Some(Wed)
WeekDay.Fri.toString // returns Fri
Of course the problem here is that you will need to keep the ordering of the names and vals in sync which is easier to do if name and val are declared on the same line.
This is a generic sorter. Called with the switch below.
dvm.PagePermissions is a property on my ViewModel of type List T in this case T is a EF6 model class called page_permission.
dvm.UserNameSortDir is a string property on the viewmodel that holds the next sort direction. The one that is actaully used in the view.
switch (sortColumn)
{
case "user_name":
dvm.PagePermissions = Sort(dvm.PagePermissions, p => p.user_name, ref sortDir);
dvm.UserNameSortDir = sortDir;
break;
case "role_name":
dvm.PagePermissions = Sort(dvm.PagePermissions, p => p.role_name, ref sortDir);
dvm.RoleNameSortDir = sortDir;
break;
case "page_name":
dvm.PagePermissions = Sort(dvm.PagePermissions, p => p.page_name, ref sortDir);
dvm.PageNameSortDir = sortDir;
break;
}
public List<T> Sort<T,TKey>(List<T> list, Func<T, TKey> sorter, ref string direction)
{
if (direction == "asc")
{
list = list.OrderBy(sorter).ToList();
direction = "desc";
}
else
{
list = list.OrderByDescending(sorter).ToList();
direction = "asc";
}
return list;
}
Try this
function recursive_array_search($needle,$haystack) {
foreach($haystack as $key=>$value) {
$current_key=$key;
if($needle==$value['uid'] OR (is_array($value) && recursive_array_search($needle,$value) !== false)) {
return $current_key;
}
}
return false;

This seems to work:

I go this from "XSLT 2.0 and XPath 2.0 Programmer's Reference, 4th Edition" by Michael Kay.
There is also a note in the "Abbreviated Syntax" section of the XML Path Language specification http://www.w3.org/TR/xpath/#path-abbrev that provided a clue.
It's simplest:
awk '{print $--NF}'
The reason the original $NF--
didn't work is because the expression is evaluated before the decrement, whereas my prefix decrement is performed before evaluation.
Just to complement m59's correct answer, here is a working jsfiddle:
<body ng-app='myApp'>
<div>
<button my-directive>Click Me!</button>
</div>
<h1>{{2+3}}</h1>
</body>
You can also do the following:
CREATE TABLE #TEMPTABLE
(
Column1 type1,
Column2 type2,
Column3 type3
)
INSERT INTO #TEMPTABLE
SELECT ...
SELECT *
FROM #TEMPTABLE ...
DROP TABLE #TEMPTABLE
An alternative to coord_flip()
is to use the ggstance
package.
The advantage is that it makes it easier to combine the graphs with other graph types and you can, maybe more importantly, set fixed scale ratios for your coordinate system.

if you don't need variable, you can define text in
translations/messages.en.yaml :
CiteExampleHtmlCode: "<b> my static text </b>"
then use it with twig:
templates/about/index.html.twig
… {{ 'CiteExampleHtmlCode' }}
or if you need multilangages like me:
… {{ 'CiteExampleHtmlCode' | trans }}
Let's have a look of https://symfony.com/doc/current/translation.html for more information about translations use.
This one worked for me.
public void RestrictNumbersOnly(TextField tf){
tf.textProperty().addListener(new ChangeListener<String>() {

tf.setText(oldValue);
}
}
});
}
Try following code snippet.
double myVal = 0;
String myVar = "Not Numeric Type";
if (Double.TryParse(myVar , out myNum)) {
// it is a number
} else {
// it is not a number

The other answers suggesting checking out the other branch, then committing to it, only work if the checkout is possible given the local modifications. If not, you're in the most common use case for git stash
:
git stash
git checkout other-branch
git stash pop
The first stash
hides away your changes (basically making a temporary commit), and the subsequent stash pop
re-applies them. This lets Git use its merge capabilities.
If, when you try to pop the stash, you run into merge conflicts... the next steps depend on what those conflicts are. If all the stashed changes indeed belong on that other branch, you're simply going to have to sort through them - it's a consequence of having made your changes on the wrong branch.
On the other hand, if you've really messed up, and your work tree has a mix of changes for the two branches, and the conflicts are just in the ones you want to commit back on the original branch, you can save some work. As usual, there are a lot of ways to do this. Here's one, starting from after you pop and see the conflicts:
# Unstage everything (warning: this leaves files with conflicts in your tree)
git reset
# Add the things you *do* want to commit here
git add -p # or maybe git add -i
git commit
# The stash still exists; pop only throws it away if it applied cleanly
git checkout original-branch
git stash pop
# Add the changes meant for this branch
git add -p
git commit
# And throw away the rest
git reset --hard
Alternatively, if you realize ahead of the time that this is going to happen, simply commit the things that belong on the current branch. You can always come back and amend that commit:
git add -p
git commit
git stash
git checkout other-branch
git stash pop
And of course, remember that this all took a bit of work, and avoid it next time, perhaps by putting your current branch name in your prompt by adding $(__git_ps1)
to your PS1 environment variable in your bashrc file. (See for example the Git in Bash documentation.)
Restarting Visual Studio solved the problem for me.
If you could reload this, you might be able to use dtypes argument.
pd.read_csv(..., dtype={'COL_NAME':'str'})
You may try the following:
System.Globalization.CultureInfo cultureinfo =
new System.Globalization.CultureInfo("nl-NL");
DateTime dt = DateTime.Parse(date, cultureinfo);
If your key is NOT guaranteed to be unique for all elements in the list, you should convert it to a Map<String, List<Choice>>
instead of a Map<String, Choice>
Map<String, List<Choice>> result =
choices.stream().collect(Collectors.groupingBy(Choice::getName));
Try the below code:
[Route("/test")]
[HttpPost]
public async Task Test()
{
using (var reader = new StreamReader(Request.Body, Encoding.UTF8))
{
var textFromBody = await reader.ReadToEndAsync();
}
}
Since security.disable option is banned from usage there is still a way to achieve it from pure config without touching any class flies (for me it creates convenience with environments manipulation and possibility to activate it with ENV variable) if you use Boot
spring.autoconfigure.exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
I had the same issue and resolved it by adding the following line in the dependencies of the project-level build.gradle:

For those, who are wondering how to get FontAwesome icons to drupal input, you have to decode_entities first like so:
$form['submit'] = array(
'#type' => 'submit',
'#value' => decode_entities(''), // code for FontAwesome trash icon
// etc.
);
What is happening is that stock_list.toArray()
is creating an Object[]
rather than a String[]
and hence the typecast is failing1.
The correct code would be:
String [] stockArr = stockList.toArray(new String[stockList.size()]);
or even
String [] stockArr = stockList.toArray(new String[0]);
For more details, refer to the javadocs for the two overloads of List.toArray
.
The latter version uses the zero-length array to determine the type of the result array. (Surprisingly, it is faster to do this than to preallocate ... at least, for recent Java releases. See https://stackoverflow.com/a/4042464/139985 for details.)
From a technical perspective, the reason for this API behavior / design is that an implementation of the List<T>.toArray()
method has no information of what the <T>
is at runtime. All it knows is that the raw element type is Object
. By contrast, in the other case, the array parameter gives the base type of the array. (If the supplied array is big enough to hold the list elements, it is used. Otherwise a new array of the same type and a larger size is allocated and returned as the result.)
1 - In Java, an Object[]
is not assignment compatible with a String[]
. If it was, then you could do this:
Object[] objects = new Object[]{new Cat("fluffy")};
Dog[] dogs = (Dog[]) objects;
Dog d = dogs[0]; // Huh???
This is clearly nonsense, and that is why array types are not generally assignment compatible.
Yeah in simulator. Some times it wont recognise the selector there is a bug it seems. Even i faced not for your code , then i just changed the action name (selector). It works
let buttonPuzzle:UIButton = UIButton(frame: CGRectMake(100, 400, 100, 50))
buttonPuzzle.backgroundColor = UIColor.greenColor()
buttonPuzzle.setTitle("Puzzle", forState: UIControlState.Normal)
buttonPuzzle.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
buttonPuzzle.tag = 22;
self.view.addSubview(buttonPuzzle)
An example selector function is here:
func buttonAction(sender:UIButton!) {
var btnsendtag:UIButton = sender
if btnsendtag.tag == 22 {
//println("Button tapped tag 22")
}
}
Packaging an artifact as POM means that it has a very simple lifecycle
package -> install -> deploy
http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html
This is useful if you are deploying a pom.xml file or a project that doesn't fit with the other packaging types.
We use pom packaging for many of our projects and bind extra phases and goals as appropriate.
For example some of our applications use:
prepare-package -> test -> package -> install -> deploy
When you mvn install the application it should add it to your locally .m2 repository. To publish elsewhere you will need to set up correct distribution management information. You may also need to use the maven builder helper plugin, if artifacts aren't automatically attached to by Maven.

To answer your question, Hibernate is an implementation of the JPA standard. Hibernate has its own quirks of operation, but as per the Hibernate docs
By default, Hibernate uses lazy select fetching for collections and lazy proxy fetching for single-valued associations. These defaults make sense for most associations in the majority of applications.
So Hibernate will always load any object using a lazy fetching strategy, no matter what type of relationship you have declared. It will use a lazy proxy (which should be uninitialized but not null) for a single object in a one-to-one or many-to-one relationship, and a null collection that it will hydrate with values when you attempt to access it.
It should be understood that Hibernate will only attempt to fill these objects with values when you attempt to access the object, unless you specify fetchType.EAGER
.
All implementation for topViewController here are not fully supporting cases when you have UINavigationController
or UITabBarController
, for those two you need a bit different handling:
For UITabBarController
and UINavigationController
you need a different implementation.
Here is code I'm using to get topMostViewController:
protocol TopUIViewController {
func topUIViewController() -> UIViewController?
}
extension UIWindow : TopUIViewController {
func topUIViewController() -> UIViewController? {
if let rootViewController = self.rootViewController {
return self.recursiveTopUIViewController(from: rootViewController)
}
return nil
}
private func recursiveTopUIViewController(from: UIViewController?) -> UIViewController? {
if let topVC = from?.topUIViewController() { return recursiveTopUIViewController(from: topVC) ?? from }
return from
}
}
extension UIViewController : TopUIViewController {
@objc open func topUIViewController() -> UIViewController? {
return self.presentedViewController
}
}
extension UINavigationController {
override open func topUIViewController() -> UIViewController? {
return self.visibleViewController
}
}
extension UITabBarController {
override open func topUIViewController() -> UIViewController? {
return self.selectedViewController ?? presentedViewController
}
}

Here is a quick start to get the gears turning...
ParkingLot is a class.
ParkingSpace is a class.
ParkingSpace has an Entrance.
Entrance has a location or more specifically, distance from Entrance.
ParkingLotSign is a class.
ParkingLot has a ParkingLotSign.
ParkingLot has a finite number of ParkingSpaces.
HandicappedParkingSpace is a subclass of ParkingSpace.
RegularParkingSpace is a subclass of ParkingSpace.
CompactParkingSpace is a subclass of ParkingSpace.
ParkingLot keeps array of ParkingSpaces, and a separate array of vacant ParkingSpaces in order of distance from its Entrance.
ParkingLotSign can be told to display "full", or "empty", or "blank/normal/partially occupied" by calling .Full(), .Empty() or .Normal()
Parker is a class.
Parker can Park().
Parker can Unpark().
Valet is a subclass of Parker that can call ParkingLot.FindVacantSpaceNearestEntrance(), which returns a ParkingSpace.
Parker has a ParkingSpace.
Parker can call ParkingSpace.Take() and ParkingSpace.Vacate().
Parker calls Entrance.Entering() and Entrance.Exiting() and ParkingSpace notifies ParkingLot when it is taken or vacated so that ParkingLot can determine if it is full or not. If it is newly full or newly empty or newly not full or empty, it should change the ParkingLotSign.Full() or ParkingLotSign.Empty() or ParkingLotSign.Normal().
HandicappedParker could be a subclass of Parker and CompactParker a subclass of Parker and RegularParker a subclass of Parker. (might be overkill, actually.)
In this solution, it is possible that Parker should be renamed to be Car.
In my case my column was a datetime it kept giving me all records. What I did is to include time, see below example
SELECT * FROM my_table where start_date > '2011-01-01 01:01:01';
The following code allows you to get the entire stackTrace with a String
format, without using APIs like log4J or even java.util.Logger
:
catch (Exception e) {
StackTraceElement[] stack = e.getStackTrace();
String exception = "";
for (StackTraceElement s : stack) {
exception = exception + s.toString() + "\n\t\t";
}
System.out.println(exception);
// then you can send the exception string to a external file.
}

If you have no concrete implementations of the class and the methods aren't static
whats the point of testing them? If you have a concrete class then you'll be testing those methods as part of the concrete class's public API.
I know what you are thinking "I don't want to test these methods over and over thats the reason I created the abstract class", but my counter argument to that is that the point of unit tests is to allow developers to make changes, run the tests, and analyze the results. Part of those changes could include overriding your abstract class's methods, both protected
and public
, which could result in fundamental behavioral changes. Depending on the nature of those changes it could affect how your application runs in unexpected, possibly negative ways. If you have a good unit testing suite problems arising from these types changes should be apparent at development time.

You should set responseType: ResponseContentType.Blob
in your GET-Request settings, because so you can get your image as blob and convert it later da base64-encoded source. You code above is not good. If you would like to do this correctly, then create separate service to get images from API. Beacuse it ism't good to call HTTP-Request in components.
Here is an working example:
Create image.service.ts
and put following code:
Angular 4:
getImage(imageUrl: string): Observable<File> {
return this.http
.get(imageUrl, { responseType: ResponseContentType.Blob })
.map((res: Response) => res.blob());
}
Angular 5+:
getImage(imageUrl: string): Observable<Blob> {
return this.httpClient.get(imageUrl, { responseType: 'blob' });
}
Important: Since Angular 5+ you should use the new HttpClient
.
The new HttpClient
returns JSON by default. If you need other response type, so you can specify that by setting responseType: 'blob'
. Read more about that here.
Now you need to create some function in your image.component.ts
to get image and show it in html.
For creating an image from Blob you need to use JavaScript's FileReader
.
Here is function which creates new FileReader
and listen to FileReader's load-Event. As result this function returns base64-encoded image, which you can use in img src-attribute:
imageToShow: any;
createImageFromBlob(image: Blob) {
let reader = new FileReader();
reader.addEventListener("load", () => {
this.imageToShow = reader.result;
}, false);
if (image) {
reader.readAsDataURL(image);
}
}
Now you should use your created ImageService
to get image from api. You should to subscribe to data and give this data to createImageFromBlob
-function. Here is an example function:
getImageFromService() {
this.isImageLoading = true;
this.imageService.getImage(yourImageUrl).subscribe(data => {
this.createImageFromBlob(data);
this.isImageLoading = false;
}, error => {
this.isImageLoading = false;
console.log(error);
});
}
Now you can use your imageToShow
-variable in HTML template like this:
<img [src]="imageToShow"
alt="Place image title"
*ngIf="!isImageLoading; else noImageFound">
<ng-template #noImageFound>
<img src="fallbackImage.png" alt="Fallbackimage">
</ng-template>
I hope this description is clear to understand and you can use it in your project.
See the working example for Angular 5+ here.
Toad for MySQL by Quest is free for non-commercial use. I really like the interface and it's quite powerful if you have several databases to work with (for example development, test and production servers).
From the website:
Toad® for MySQL is a freeware development tool that enables you to rapidly create and execute queries, automate database object management, and develop SQL code more efficiently. It provides utilities to compare, extract, and search for objects; manage projects; import/export data; and administer the database. Toad for MySQL dramatically increases productivity and provides access to an active user community.
You could use sum
function to achieve that as @EdChum mentioned in the comment:
df['C'] = df[['A', 'B']].sum(axis=1)
In [245]: df
Out[245]:
A B C
0 1 4 5
1 2 6 8
2 3 9 12
Keep it simple
dataGridView1.Columns.Add("newColumnName", "Column Name in Text");
To add rows
dataGridView1.Rows.Add("Value for column#1"); // [,"column 2",...]
If you want to append to the file, open it with 'a'
. If you want to seek through the file to find the place where you should insert the line, use 'r+'
. (docs)
If you want to keep the keys of the initial array and also add an array that has keys, then use the function below:
function insertArrayAtPosition( $array, $insert, $position ) {
/*
$array : The initial array i want to modify
$insert : the new array i want to add, eg array('key' => 'value') or array('value')
$position : the position where the new array will be inserted into. Please mind that arrays start at 0
*/
return array_slice($array, 0, $position, TRUE) + $insert + array_slice($array, $position, NULL, TRUE);
}
Call example:
$array = insertArrayAtPosition($array, array('key' => 'Value'), 3);
After using pngcheck and resave all my image files to *.png, the problem still.
Finally, I found the issue is about *.9.png files. Open and check all your 9-Patch files, make sure that all files have black lines as below, if don't have, just click the white place and add it, then save it.
Instead of "w"
use "a"
(append) mode with open
function:
with open("games.txt", "a") as text_file:
In case of image stacks, I find it easier to use scikit-image
to read, and matplotlib
to show or save. I have handled 16-bit TIFF image stacks with the following code.
from skimage import io
import matplotlib.pyplot as plt
# read the image stack
img = io.imread('a_image.tif')
# show the image
plt.imshow(mol,cmap='gray')
plt.axis('off')
# save the image
plt.savefig('output.tif', transparent=True, dpi=300, bbox_inches="tight", pad_inches=0.0)
If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing.
var canvas = document.getElementById("myCanvas");
var canvasWidth = canvas.width;
var canvasHeight = canvas.height;
var ctx = canvas.getContext("2d");
var canvasData = ctx.getImageData(0, 0, canvasWidth, canvasHeight);
// That's how you define the value of a pixel //
function drawPixel (x, y, r, g, b, a) {
var index = (x + y * canvasWidth) * 4;
canvasData.data[index + 0] = r;
canvasData.data[index + 1] = g;
canvasData.data[index + 2] = b;
canvasData.data[index + 3] = a;
}
// That's how you update the canvas, so that your //
// modification are taken in consideration //
function updateCanvas() {
ctx.putImageData(canvasData, 0, 0);
}
Then, you can use it in this way :
drawPixel(1, 1, 255, 0, 0, 255);
drawPixel(1, 2, 255, 0, 0, 255);
drawPixel(1, 3, 255, 0, 0, 255);
updateCanvas();

sounds like the 'first line' you're talking of is your table-header - so you realy should think of using thead
and tbody
in your markup (click here) which would result in 'better' markup (semantically correct, useful for things like screenreaders) and easier, cross-browser-friendly possibilitys for css-selection (table thead ... { ... }
)
This is what worked for me, for my case it was a post for login request :
var client = new RestClient("http://www.example.com/1/2");
var request = new RestRequest();
request.Method = Method.POST;
request.AddHeader("Accept", "application/json");
request.Parameters.Clear();
request.AddParameter("application/json", body , ParameterType.RequestBody);
var response = client.Execute(request);
var content = response.Content; // raw content as string
body :
{
"userId":"[email protected]" ,
"password":"welcome"
}
You don't need any date-specific functions for this, it's just string manipulation:
var parts = fecha2.value.split('-');
var newdate = parts[1]+'-'+parts[2]+'-'+(parseInt(parts[0], 10)%100);
New Function and apply() together works also
var a=new Function('alert(1);')
a.apply(null)

If the file is only numerical values separated by tabs, try using the csv library: http://docs.python.org/library/csv.html (you can set the delimiter to '\t')
If you have a textual file in which every line represents a row in a matrix and has integers separated by spaces\tabs, wrapped by a 'arrayname = [...]' syntax, you should do something like:
import re
f = open("your-filename", 'rb')
result_matrix = []
for line in f.readlines():
match = re.match(r'\s*\w+\s+\=\s+\[(.*?)\]\s*', line)
if match is None:
pass # line syntax is wrong - ignore the line
values_as_strings = match.group(1).split()
result_matrix.append(map(int, values_as_strings))
during train test split you might have done a mistake
x_train,x_test,y_train,y_test=sklearn.model_selection.train_test_split(X,Y,test_size)

x_train,y_train,x_test,y_test=sklearn.model_selection.train_test_split(X,Y,test_size)

A string
is a sequence of characters. So it makes sense to have an empty string
, which is just an empty sequence of characters.
But DateTime
is just a single value, so it's doesn't make sense to talk about an “empty” DateTime
.
If you want to represent the concept of “no value”, that's represented as null
in .Net. And if you want to use that with value types, you need to explicitly make them nullable. That means either using Nullable<DateTime>
, or the equivalent DateTime?
.
DateTime
(just like all value types) also has a default value, that's assigned to uninitialized fields and you can also get it by new DateTime()
or default(DateTime)
. But you probably don't want to use it, since it represents valid date: 1.1.0001 0:00:00.
SELECT column1 FROM table WHERE ISNUMERIC(column1) = 1
Note, as Damien_The_Unbeliever has pointed out, this will include any valid numeric type.
To filter out columns containing non-digit characters (and empty strings), you could use
SELECT column1 FROM table WHERE column1 not like '%[^0-9]%' and column1 != ''
You can use C++20 std::format
or the fmt::format
function from the {fmt} library, std::format
is based on:
#include <fmt/core.h>
int main()
std::string s = fmt::format("{:.2f}", 3.14159265359); // s == "3.14"
}
where 2
is a precision.
Compatibility with older browsers can be a drag, so be adviced.
If that is not a problem then go ahead. Run the snippet. Go to full page view and resize. Center will resize itself with no changes to the left or right divs.
Change left and right values to meet your requirement.
Thank you.
Hope this helps.

This can't be done with pure HTML.
However if you have access to PHP on the Apache server (you tagged the post "apache") it can be done easilly - se the PHP glob function. If not - you might try Server Side Include - it's an Apache thing, and I don't know much about it.
try something using a for loop
for i in `egrep -lR "YOURSEARCH" .` ; do echo $i; sed 's/f/k/' <$i >/tmp/`basename $i`; mv /tmp/`basename $i` $i; done
not pretty, but should do.
Another option would be to go with:
nmap <C-d> mzyyp`z
gives you the advantage of preserving the cursor position.
I create wrapper for this case:
func addDefaultHeaders(fn http.HandlerFunc) http.HandlerFunc {
return func(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Access-Control-Allow-Origin", "*")
fn(w, r)
}
}
I was designing a html email and had a similar problem. But having every cell with the fixed width is not what I want. I'd like to have the equal spacing between the contents of the columns, like the following
|---something---|---a very long thing---|---short---|
After a lot of trial and error, I came up with the following
<style>
.content {padding: 0 20px;}
</style>
table width="400"
tr
td
a.content something
td
a.content a very long thing
td
a.content short
Issues of concern:
Outlook 2007/2010/2013 don't support padding. Having the width of the table set will allow the widths of the columns to automatically set. This way, though the contents will not have equal spacing. They at least have some spacing between them.
Automatic width setting for table columns will not give equal spacing between the contents The padding added for the contents will force the equal spacing.
Data type "int" cannot be more than 10 digits, additionally the "Len()" function works on ints, so there's no need to convert the int to a string before calling the len() function.
Lastly, you are not taking into account the case where the size of your int > the total number of digits you want it padded to (@intLen).
Therefore, a more concise / correct solution is:
CREATE FUNCTION rf_f_CIntToChar(@intVal Int, @intLen Int) RETURNS nvarchar(10)
AS
BEGIN
IF @intlen > 20 SET @intlen = 20
IF @intlen < LEN(@intVal) RETURN RIGHT(CONVERT(nvarchar(10), @intVal), @intlen)
RETURN REPLICATE('0', @intLen - LEN(@intVal)) + CONVERT(nvarchar(10), @intVal)
END
First of all, you really should be including the position on absolutely positioned elements or you will come across odd and confusing behavior; you probably want to add top: 0; left: 0
to the CSS for both of your absolutely positioned elements. You'll also want to have position: relative
on .container_row
if you want the absolutely positioned elements to be positioned with respect to their parent rather than the document's body:
If the element has 'position: absolute', the containing block is established by the nearest ancestor with a 'position' of 'absolute', 'relative' or 'fixed' ...
Your problem is that position: absolute
removes elements from the normal flow:
It is removed from the normal flow entirely (it has no impact on later siblings). An absolutely positioned box establishes a new containing block for normal flow children and absolutely (but not fixed) positioned descendants. However, the contents of an absolutely positioned element do not flow around any other boxes.
This means that absolutely positioned elements have no effect whatsoever on their parent element's size and your first <div class="container_row">
will have a height of zero.
So you can't do what you're trying to do with absolutely positioned elements unless you know how tall they're going to be (or, equivalently, you can specify their height). If you can specify the heights then you can put the same heights on the .container_row
and everything will line up; you could also put a margin-top
on the second .container_row
to leave room for the absolutely positioned elements. For example:
You might be do that its works 100% .

Don't use the word "click" as the function name. It's a reserved keyword in JavaScript. In the bellow code I’ve used "hello" function instead of "click"
<html>
<head>
<title>Space Clicker</title>
</head>
<body>
<script type="text/javascript">
var clicks = 0;
function hello() {
clicks += 1;
document.getElementById("clicks").innerHTML = clicks;
};
</script>
<button type="button" onclick="hello()">Click me</button>
<p>Clicks: <a id="clicks">0</a></p>
</body></html>
All the code is client side, I hope you fine this helpful:
First thing there are 3 functions we will use:
function setCookie(c_name, value, exdays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
document.cookie = c_name + "=" + c_value;
}
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
x = x.replace(/^\s+|\s+$/g, "");
if (x == c_name) {
return unescape(y);
}
}
}
function DeleteCookie(name) {
document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
}
Now we will start with the page load:
$(window).load(function () {
//if IsRefresh cookie exists
var IsRefresh = getCookie("IsRefresh");
if (IsRefresh != null && IsRefresh != "") {
//cookie exists then you refreshed this page(F5, reload button or right click and reload)
//SOME CODE
DeleteCookie("IsRefresh");
}
else {
//cookie doesnt exists then you landed on this page
//SOME CODE
setCookie("IsRefresh", "true", 1);
}
})
As a DBA, You must schedule the backup of MySQL Database in case of any issues so that you can recover your databases from the current backup.

You can use awk
with a system
call readlink
to get the equivalent of an ls
output with full symlink paths. For example:
ls | awk '{printf("%s ->", $1); system("readlink -f " $1)}'
Will display e.g.
thin_repair ->/home/user/workspace/boot/usr/bin/pdata_tools
thin_restore ->/home/user/workspace/boot/usr/bin/pdata_tools
thin_rmap ->/home/user/workspace/boot/usr/bin/pdata_tools

touch ->/home/user/workspace/boot/usr/bin/busybox
true ->/home/user/workspace/boot/usr/bin/busybox
emulator -writable-system
For people using an Emulator: Another possibility is that you need to start the emulator with -writable-system. That was the only thing that worked for me when using the standard emulator packaged with android studio with a 4.1 image. Check here: https://stackoverflow.com/a/41332316/4962858
You can use the printf
method, like so:
System.out.printf("%.2f", val);
In short, the %.2f
syntax tells Java to return your variable (val
) with 2 decimal places (.2
) in decimal representation of a floating-point number (f
) from the start of the format specifier (%
).
There are other conversion characters you can use besides f
:
d
: decimal integero
: octal integere
: floating-point in scientific notationHere is the code to read the excel data by column.
public ArrayList<String> extractExcelContentByColumnIndex(int columnIndex){
ArrayList<String> columndata = null;

File f = new File("sample.xlsx")
FileInputStream ios = new FileInputStream(f);
XSSFWorkbook workbook = new XSSFWorkbook(ios);
XSSFSheet sheet = workbook.getSheetAt(0);
Iterator<Row> rowIterator = sheet.iterator();
columndata = new ArrayList<>();
while (rowIterator.hasNext()) {
Row row = rowIterator.next();
Iterator<Cell> cellIterator = row.cellIterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
if(row.getRowNum() > 0){ //To filter column headings
if(cell.getColumnIndex() == columnIndex){// To match column index
switch (cell.getCellType()) {
case Cell.CELL_TYPE_NUMERIC:
columndata.add(cell.getNumericCellValue()+"");
break;
case Cell.CELL_TYPE_STRING:
columndata.add(cell.getStringCellValue());
break;
}
}
}
}
}
ios.close();
System.out.println(columndata);
} catch (Exception e) {
e.printStackTrace();
}
return columndata;
}
update:
I found the terms of use from Google Map:
Section 10.5
No caching or storage. You will not pre-fetch, cache, index, or store any Content to be used outside the Service, except that you may store limited amounts of Content solely for the purpose of improving the performance of your Maps API Implementation due to network latency (and not for the purpose of preventing Google from accurately tracking usage), and only if such storage: is temporary (and in no event more than 30 calendar days); is secure; does not manipulate or aggregate any part of the Content or Service; and does not modify attribution in any way.
It means we can cache for limited time actually
You can load an XML document into an XMLType, then query it, e.g.:
DECLARE
x XMLType := XMLType(
'<?xml version="1.0" ?>

<Address>
<State>California</State>
<City>Los angeles</City>
</Address>
</row>
<row>

I am reproducing the same issue and it's really annoying. I've found these useful:

You can try the Class Based View called RedirectView
from django.views.generic.base import RedirectView
urlpatterns = patterns('',
url(r'^$', 'macmonster.views.home'),
#url(r'^macmon_home$', 'macmonster.views.home'),
url(r'^macmon_output/$', 'macmonster.views.output'),
url(r'^macmon_about/$', 'macmonster.views.about'),
url(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
)
Notice how as url
in the <url_to_home_view>
you need to actually specify the url.
permanent=False
will return HTTP 302, while permanent=True
will return HTTP 301.
Alternatively you can use django.shortcuts.redirect
Update for Django 2+ versions
With Django 2+, url()
is deprecated and replaced by re_path()
. Usage is exactly the same as url()
with regular expressions. For replacements without the need of regular expression, use path()
.
from django.urls import re_path
re_path(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
You add your ActionListener
twice to button
. So correct your code for button2
to
JButton button2 = new JButton("hello agin2");
panel.add(button2);
button2.addActionListener (new Action2());//note the button2 here instead of button
Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater
For reading full response in Angular you should add the observe option:
{ observe: 'response' }
return this.http.get(`${environment.serverUrl}/api/posts/${postId}/comments/?page=${page}&size=${size}`, { observe: 'response' });
To my knowledge the only difference is the scope of the effects as Strommy said. NOLOCK hint on a table and the READ UNCOMMITTED on the session.
As to problems that can occur, it's all about consistency. If you care then be aware that you could get what is called dirty reads which could influence other data being manipulated on incorrect information.
I personally don't think I have seen any problems from this but that may be more due to how I use nolock. You need to be aware that there are scenarios where it will be OK to use. Scenarios where you are mostly adding new data to a table but have another process that comes in behind to check for a data scenario. That will probably be OK since the major flow doesn't include going back and updating rows during a read.
Also I believe that these days you should look into Multi-version Concurrency Control. I believe they added it in 2005 and it helps stop the writers from blocking readers by giving readers a snapshot of the database to use. I'll include a link and leave further research to the reader:
I'm using Android Studio 3.0.1

Section 2 of RFC 2368 says that the body
field is supposed to be in text/plain
format, so you can't do HTML.
However even if you use plain text it's possible that some modern mail clients would render a URL as a clickable link anyway, though.
I encountered this issue and the cause was due to Kaspersky Protection plugin on the browser. If you are encountering this, try to disable your plugins and see if that fixes your issue.
Strictly stated you must check all of the following: defined, not empty AND not None.
For "normal" variables it makes a difference if defined and set or not set. See foo
and bar
in the example below. Both are defined but only foo
is set.
On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz
and xyz.msg
in the example below:
cat > test.yml <<EOF
- hosts: 127.0.0.1
vars:
foo: "" # foo is defined and foo == '' and foo != None
bar: # bar is defined and bar != '' and bar == None
tasks:
- debug:
msg : ""
register: xyz # xyz is defined and xyz != '' and xyz != None
# xyz.msg is defined and xyz.msg == '' and xyz.msg != None
- debug:
msg: "foo is defined and foo == '' and foo != None"
when: foo is defined and foo == '' and foo != None
- debug:
msg: "bar is defined and bar != '' and bar == None"
when: bar is defined and bar != '' and bar == None
- debug:
msg: "xyz is defined and xyz != '' and xyz != None"
when: xyz is defined and xyz != '' and xyz != None
- debug:

when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
- debug:

In WPF an image is typically loaded from a Stream or an Uri.
BitmapImage supports both and an Uri can even be passed as constructor argument:
var uri = new Uri("http://...");
var bitmap = new BitmapImage(uri);
If the image file is located in a local folder, you would have to use a file://
Uri. You could create such a Uri from a path like this:
var path = Path.Combine(Environment.CurrentDirectory, "Bilder", "sas.png");
var uri = new Uri(path);
If the image file is an assembly resource, the Uri must follow the the Pack Uri scheme:
var uri = new Uri("pack://application:,,,/Bilder/sas.png");
In this case the Visual Studio Build Action for sas.png
would have to be Resource
.
Once you have created a BitmapImage
and also have an Image control like in this XAML
<Image Name="image1" />
you would simply assign the BitmapImage to the Source
property of that Image control:
image1.Source = bitmap;
I put together a short function that allows for a little more flexibility when inserting a row:
def insert_row(idx, df, df_insert):
dfA = df.iloc[:idx, ]
dfB = df.iloc[idx:, ]
df = dfA.append(df_insert).append(dfB).reset_index(drop = True)
return df
which could be further shortened to:
def insert_row(idx, df, df_insert):
return df.iloc[:idx, ].append(df_insert).append(df.iloc[idx:, ]).reset_index(drop = True)
Then you could use something like:
df = insert_row(2, df, df_new)
where 2
is the index position in df
where you want to insert df_new
.
you cannot assign null to a var type.
If you assign null the compiler cannot find the variable you wanted in var place.
throws error: Cannot assign <null> to an implicitly-typed local variable
you can try this:
var dummy =(string)null;
Here compiler can find the type you want so no problem
You can assign some empty values.
var dummy = string.Empty;
or
var dummy = 0;

The error "Directory 'blah/.svn' containing working copy admin area is missing" occurred when I attempted to add the directory to the repository, but did not have enough filesystem privileges to do so. The directory was not already in the repository, but it was claiming to be under version control after the failed add.
Checking out a copy of the parent directory to another location, and replacing the .svn folder in the parent dir of the working copy allowed me to add and commit the new directory successfully (after fixing the file permissions, of course).
Executing Linq queries can generate extra threads. When I try to execute code that uses Linq query collection in the immediate window it often refuses to run because not enough threads are available to the debugger.
As others have said, for threads to exit when they are finished is perfectly normal.
You can delete the browser cache by setting these headers:
<?php
header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
?>
When the executable ends (exits) it returns a value to the shell that ran it. exit(0)
usually indicates that all is well, whilst exit(1)
indicates that something has gone amiss.

In case you decide to use dangerous code that is subject to breakage, this extension function will fetch a key from a Dictionary<K,V>
according to its internal indexing (which for Mono and .NET currently appears to be in the same order as you get by enumerating the Keys
property).
It is much preferable to use Linq: dict.Keys.ElementAt(i)
, but that function will iterate O(N); the following is O(1) but with a reflection performance penalty.
using System;
using System.Collections.Generic;
using System.Reflection;
public static class Extensions
{
public static TKey KeyByIndex<TKey,TValue>(this Dictionary<TKey, TValue> dict, int idx)
{
Type type = typeof(Dictionary<TKey, TValue>);
FieldInfo info = type.GetField("entries", BindingFlags.NonPublic | BindingFlags.Instance);
if (info != null)
{
// .NET
Object element = ((Array)info.GetValue(dict)).GetValue(idx);
return (TKey)element.GetType().GetField("key", BindingFlags.Public | BindingFlags.Instance).GetValue(element);
}
// Mono:
info = type.GetField("keySlots", BindingFlags.NonPublic | BindingFlags.Instance);
return (TKey)((Array)info.GetValue(dict)).GetValue(idx);
}
};
The problem is that certain third party libraries require file pathnames rather than input streams. Most of the answers don't address this issue.
In this case, one workaround is to copy the resource contents into a temporary file. The following example uses jUnit's TemporaryFolder
.
private List<String> decomposePath(String path){
List<String> reversed = Lists.newArrayList();
File currFile = new File(path);
while(currFile != null){
reversed.add(currFile.getName());
currFile = currFile.getParentFile();
}
return Lists.reverse(reversed);
}
private String writeResourceToFile(String resourceName) throws IOException {
ClassLoader loader = getClass().getClassLoader();
InputStream configStream = loader.getResourceAsStream(resourceName);
List<String> pathComponents = decomposePath(resourceName);
folder.newFolder(pathComponents.subList(0, pathComponents.size() - 1).toArray(new String[0]));
File tmpFile = folder.newFile(resourceName);
Files.copy(configStream, tmpFile.toPath(), REPLACE_EXISTING);
return tmpFile.getAbsolutePath();
}
Items drawn to the canvas are persistent. create_rectangle
returns an item id that you need to keep track of. If you don't remove old items your program will eventually slow down.
From Fredrik Lundh's An Introduction to Tkinter:
Note that items added to the canvas are kept until you remove them. If you want to change the drawing, you can either use methods like
coords
,itemconfig
, andmove
to modify the items, or usedelete
to remove them.

You're calling writer.close();
after you've done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method.
public void writeToFile(){
String file_text= pedStatusText + " " + gatesStatus + " " + DrawBridgeStatusText;
try {
writer.write(file_text);
writer.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
And add a method cleanUp
to close the stream.
public void cleanUp() {
writer.close();
}
This means that you have the responsibility to make sure that you're calling cleanUp
when you're done writing to the file. Failure to do this will result in memory leaks and resource locking.
EDIT: You can create a new stream each time you want to write to the file, by moving writer
into the writeToFile()
method..
public void writeToFile() {
FileWriter writer = new FileWriter("status.txt", true);
// ... Write to the file.
writer.close();
}
This Works
function saveBase64AsFile(base64, fileName) {
var link = document.createElement("a");
document.body.appendChild(link);
link.setAttribute("type", "hidden");
link.href = "data:text/plain;base64," + base64;
link.download = fileName;
link.click();
document.body.removeChild(link);
}
Based on the answer above but with some changes
